                          SECOND SUPPLEMENTAL AGREEMENT


            SECOND SUPPLEMENTAL AGREEMENT dated as of the 15th day of March,
1995, between THE BANK OF NEW YORK as trustee under the will of Harold D. Uris,
deceased, having an office at 48 Wall Street, New York, New York 10286
(hereinafter called "Landlord"), and COLGATE-PALMOLIVE COMPANY, a Delaware
corporation, having an office at 300 Park Avenue, New York, New York 10022
(hereinafter called "Tenant").

                              W I T N E S S E T H:

      WHEREAS:

            A. Landlord and Tenant have heretofore entered into a certain lease
dated August 15, 1978 (such lease, as the same has been amended by First
Supplemental Agreement dated as of January 1, 1989 and as may hereafter be
amended, is hereinafter collectively called the "Lease"), with respect to entire
Floors through 2-18, inclusive, 22 and 25 in their entirety, together with a
portion of space in the ground floor receiving area comprised of approximately
161 square feet (hereinafter called the "Premises") in the building (hereinafter
called the "Building") known as 300 Park Avenue, New York, New York for a term
(the "Initial Term") ending on June 30, 2000 (the "Term Expiration Date"), or on
such earlier date upon which said term may expire or be terminated pursuant to 
any conditions of limitation or other provisions of the Lease or pursuant to 
law;

            B.    The parties hereto desire further to modify certain
provisions of the Lease with respect to the Initial Term thereof, on
terms and conditions more particularly hereinafter set forth in this
Agreement; and

            C. Tenant desires to extend the term of the Lease beyond the Term
Expiration Date for the entire portion of the Premises less the Optional Space
(hereinafter defined), and Landlord has agreed so to extend the term of the
Lease, provided certain provisions of the Lease in effect during the Initial
Term shall be modified for the period of the New Lease Term (hereinafter
defined) on terms and conditions more particularly hereinafter set forth.

            D. Tenant desires the right to elect, upon notice more particularly
described herein, to extend the term of the Lease to all or a portion of the
Optional Space, and Landlord has agreed to grant such right on terms and
conditions more particularly described herein.

            NOW, THEREFORE, in consideration of the premises and mutual
covenants hereinafter contained, the parties hereto hereby modify the Lease as
follows:

            1. All terms defined in the Lease shall, unless otherwise defined
herein, have the same meaning ascribed to them in the Lease.

            2. Effective as of the date hereof, the term granted by the Lease
with respect to the Premises less the Optional Space is hereby extended (the
"New Lease Term") upon and subject to the covenants, agreements, terms,
provisions and conditions of the Lease (and subject to the modifications thereof
herein contained) so that the extended term shall commence on July 1, 2000 (the
"New Lease Commencement Date" and expire on June 30, 2010 (the "New Lease
Expiration Date") or on such earlier date upon which said term (as so extended)
may expire or be terminated pursuant to any of the conditions of limitation or
other provisions of the Lease or pursuant to law, all (except as otherwise may
be provided in this Second Supplemental Agreement) with the same force and
effect as if said term (as so extended) were the term initially granted by the
Lease but, unless herein otherwise expressly provided, nothing herein contained
shall operate to extend the period for which the term of the Lease may be
further renewed, or extended, pursuant to any option granted to Tenant thereby.

            Landlord and Tenant agree that for all purposes of this Lease in the
New Lease Term exclusively, the term "Premises" shall be deemed to refer to the
Premises together with so much of the Optional Space, if any, as shall be the
subject of Tenant's Option Notice (hereinafter defined), as if such Optional
Space had been the subject of the term extension herein granted.

            3. Effective as of the date hereof and for the remainder of the
term, Section 3.04 is hereby modified by (i) the deletion of the phrase "a
receiving television aerial on the roof of the Building" in the third line of
said Subsection, and the insertion of the words, "Microwave dish of dimensions,
placement on the roof of the Building and wiring configuration connected to the
Premises as shall be satisfactory in all respects to Landlord in the exercise of
its reasonable discretion, at the sole cost and expense of Tenant" in lieu
thereof, (ii) the deletion of the phrase "occupying space above the first floor"
in the tenth line of said Subsection and (iii) the addition of the following
phrase after the phrase "vending machines," in the eighth line of said
Subsection: "and a mailroom, a word processing center, a reproduction and
copying facility (each of which shall be exclusively for Tenant's use,
notwithstanding any other provision of this Lease to the contrary contained)."


            In addition to the foregoing, effective as of the date hereof and
for the remainder of the term, Section 3.04 is hereby modified by the addition
of the following as the final sentence of such section:

                 "In the event Tenant shall elect to place a microwave dish on
            the roof, Tenant's placement and operation therefor shall be without
            charge to Landlord; however, Tenant shall have the exclusive
            obligation to pay any and all charges, fees or taxes of any kind
            imposed from time to time by any governmental authority in
            connection with the placement or operation of a microwave dish. In
            addition, in the event such installation and operation shall subject
            the Building to any special assessment or increase in real property
            taxes, Tenant shall have the exclusive obligation to pay such
            assessment or tax increase. Tenant covenants and agrees to remove
            the installed apparatus and any related equipment or wiring upon the
            expiration or sooner termination of the Lease or the discontinuance
            of use of the microwave dish, which ever occurs first."

            4. Effective as of the date hereof and for the remainder of the term
of the Lease, Section 3.05(a) is hereby modified by the addition of the
following provisions at the end of such subsection:

                 In the event that Tenant elects to install an information desk
            in the lobby of the Building pursuant to Tenant's right under this
            Section 3.05(a), nothing herein contained shall be deemed to cause
            Landlord to be in breach of Tenant's aforesaid right and license
            with respect to the information lobby desk in the event that the
            preparation, undertaking and completion of the Base Building
            Improvements (hereinafter defined) shall require the relocation or
            reconfiguration of the information lobby desk or the temporary
            cessation of operations thereof in connection with the completion of
            such renovations. Landlord's approval as to the size, format,
            location, signage or promotional material erected at Tenant's
            information lobby desk shall be required, which approval shall not
            be unreasonably withheld or delayed. To the 
            extent reasonably possible, Landlord shall confine all work
            involving Tenant's lobby information desk (if installed) and the
            lobby information desk currently serving the Premises, to times
            other than from 8:00 a.m. to 6:00 p.m. on business days, provided
            that Landlord's compliance herewith shall not result in excessive
            cost increases or unreasonable delays in completion of lobby
            renovation work. Landlord shall perform such repairs, alterations or
            renovations to the information desks with all due diligence and
            otherwise take such action as may be necessary to minimize the
            period during which use of the lobby information desks are
            interrupted or interfered with and shall make such renovations in
            conformance with the plans for the Base Building Improvements.

                  Subject to the provisions hereof, Landlord covenants to
            maintain and continue to operate the information desk currently
            installed in the lobby of the Building through the remainder of the 
            term of the Lease.

                  Tenant shall have an irrevocable right and license during the
            term of this Lease to install, maintain and remove, at Tenant's
            expense, a bank of its corporate phones serving the Premises in the
            lobby of the Building at a location and design selected by Tenant,
            and reasonably acceptable to Landlord."

            5. Effective as of the date hereof and for the remainder of the
term, Section 11.01 is hereby deleted and the following provision shall be
substituted in its place and stead:

                  "Section 11.01. Except as otherwise expressly provided in this
            Lease, any bills, statements, consents, notices, demands, requests,
            default notices or other communications given or required to be
            given under this Lease shall be in writing and shall be deemed
            sufficiently given or rendered if delivered by hand (against a
            signed receipt) or if sent by express, registered or certified mail
            (return receipt requested), or by Federal Express or other
            nationally recognized delivery service, addressed:


            if to Tenant (a) at Tenant's address set forth in this Lease, Attn:
            Real Estate Vice President and Attn: Office of General Counsel, or
            (b) at any place where Tenant or any agent or employee of Tenant may
            be found if mailed subsequent to Tenant's vacating, deserting,
            abandoning or surrendering the Premises, in each case with a copy to
            Skadden, Arps, Slate, Meagher & Flom, 919 Third Avenue, New York,
            New York 10022, Attn: Wallace L. Schwartz, Esq., or

            if to Landlord (x) at Landlord's address set forth in this Lease,

            10112, Attn: Arthur J. Mahon, Esq. and Attn: Joseph J. Onufrak, Esq.
            and (z) each mortgagee and ground lessor of Landlord which shall
            have requested same, by notice given in accordance with the
            provisions of this Article at the address designated by such
            mortgagee or ground lessor, or to such other address(es) as
            Landlord, Tenant or any mortgagee or ground lessor of Landlord may
            designate as its new addresses for such purpose by notice given to
            the other in accordance with the provisions of this Article. Any
            such bill, statement, consent, notice, demand, request or other
            communication shall be deemed to have been rendered or given on the
            date when it shall have been hand delivered (against a signed
            receipt) or three (3) business days from when it shall have been
            mailed as provided in this Article.

            6.    (i)  Effective as of the date hereof and for
the remainder of the term, Section 17.02(c) shall be deemed
modified by adding thereto the following sentences at the end
of such section:

                 "Subject to the provisions of Section 17.12, nothing herein
            contained shall be construed to authorize Tenant to assume any
            responsibility or to grant to Tenant any right to perform window
            cleaning services in the Premises. In the event Tenant shall elect
            to assume certain cleaning services in the Initial Term,
            notwithstanding the equitable adjustment of the fixed rent provided
            herein for the cleaning of the Premises, Tenant shall continue to be
            obligated to pay the Tenant's Proportionate Share of the cost of
            services provided by the cleaning services contractor for the common
            areas of the Building, which payment is made by Tenant as additional
            rent pursuant to Section 26.05 of the Lease.

                  In the event Tenant shall elect to assume certain cleaning
            services during the New Lease Term, and continuing through the
            remainder of the term, then in addition to the equitable adjustment
            to the fixed rent provided herein, for all calculations of Tenant's
            payments of Operating Expenses with respect to periods after the
            effective date of the termination of Landlord's cleaning services,
            Landlord's cost of such cleaning services with respect to the
            Premises (exclusive of window cleaning, common area cleaning and any
            and all other services rendered by the cleaning contractor other
            than the cleaning of the Premises) shall be excluded from Operating
            Expenses both for the Base Year and for each Operational Year (or
            partial Operational Year) after the date of such termination (taking
            into account any differences in services rendered under the cleaning
            contract for the Base Year and the Operational Years thereafter).
            Landlord agrees to grant Tenant reasonable access to Landlord's
            books and records for the purpose of verifying the adjustment made
            to Operating Expenses resulting from the termination of cleaning
            services, and to have and make copies of any and all bills and
            vouchers relating thereto."

                  (ii) Effective as of the date of substantial completion of the
            Base Building Improvements as contemplated under the Retrofit Report
            (as such terms are hereinafter defined), and for the remainder of
            the term of the Lease, Section 17.03 shall be deemed modified by the
            deletion of the following sentences:

                  "Landlord represents that the air conditioning systems
            referred to in this Section 17.03 is capable of providing interior
            conditions of 78 degrees F. dry bulb and 50 percent relative
            humidity when outside conditions are 95 degrees F. dry bulb and 75
            degrees F. wet bulb, and 70 degrees F. dry bulb (minimum) when
            outside conditions are 0 degrees F. dry bulb; with fresh air
            provided in a quantity not less than .35 cubic feet per minute per
            square foot of Tenant's floor area. The foregoing specifications are
            based upon an average occupancy of not more than one person per 100
            square feet, and upon a combined lighting and standard electrical
            load not to exceed 4 watts per square foot"; and by adding thereto
            the following sentence in its place and stead, "Landlord represents
            and warrants that the systems providing heating, ventilation and air
            conditioning to the Premises shall, at all times, meet the
            specifications set forth on Schedule 17.03 attached hereto and made
            a part hereof (the "HVAC Schedule")."


                  (iii) Effective as of the date hereof and for the remainder of
            the term of the Lease, Section 17.06 is hereby deleted and the
            following provision shall be substituted in its place and stead:

                  "Section 17.06. As used in this Lease, the term holidays shall
            mean all days observed as holidays by such unions as are actually
            representing any Building employees who are actually performing the
            applicable building services referred to herein. Notwithstanding
            anything contained in this Section 17.06 or in this Lease to the
            contrary, Tenant agrees that (1) the holidays set forth on Schedule
            17.06 attached hereto are the correct observed holidays and (2)
            Landlord shall not be obligated to perform cleaning services in the
            Building on holidays as stated in the building service union
            agreements."

                  (iv) Effective as of the date hereof and for the remainder of
            the term of the Lease, whenever the terms "reasonable charge(s),"
            "Landlord's cost," "cost to Landlord" and terms of similar import
            and meaning are used in Article 17 in connection with charges for
            certain services provided by Landlord to Tenant, Landlord covenants
            that the calculation of such "cost" or "charge" shall be determined
            in a manner consistent with the methodology utilized by Landlord, or
            any agent of Landlord providing any such service, prior to the date
            hereof, provided that notwithstanding the foregoing provisions,
            nothing herein contained shall be deemed to deny to Landlord the
            right to reasonably amend or modify such calculations or
            methodology, from time to time in conformity with then-current
            industry standards, accounting practices or tax-reporting or
            tax-rule procedures or under a Requirement of Law. Landlord does not
            know of any such amendment or modification to be made as of the date
            hereof. Notwithstanding the foregoing, effective as of the date of
            substantial completion of the applicable elements of the Base
            Building Renovations, the calculation of such "costs" or "charges"
            shall be adjusted to reflect, as applicable, the cessation of
            certain Landlord services or equipment theretofore provided to
            Tenant (such cessation being the result of the Base Building
            Improvements).

            7. (i) Effective as of the date hereof and for the remainder of the
term of the Lease, the following provisions shall be added to Article 24 of the
Lease:

                  "Section 24.08. (a) Tenant shall, immediately upon the
            completion of the portion of the Base Building Improvements relating
            to the "buss duct riser" and installation of separate meters and all
            wiring in connection therewith in the Premises, at its sole cost and
            expense, contract for the supplying of such electric energy with a
            public utility company of its choice. Landlord shall cooperate with
            Tenant in all reasonable respects to facilitate and authorize such
            direct metering. Landlord shall permit the use of its wires, risers,
            conduits, feeders and switchboards, to the extent presently
            available, suitable and of supplying such electric energy; provided,
            however, that Tenant, at Tenant's cost and expense, shall furnish
            and install at a location in the Building selected by Tenant, and
            reasonably acceptable to Landlord, and maintain and keep in good
            repair any necessary metering equipment used in connection with
            measuring Tenant's consumption of electric energy so supplied to
            Tenant by said public utility. Upon notice from Tenant of the
            effective installation of the "buss duct riser" and Tenant's
            metering equipment and the transfer of direct access to electric
            energy by Tenant, as part of the cost of the Base Building
            Improvements, Landlord shall arrange to discontinue the furnishing
            of electric energy to the Premises other than any areas on each
            floor of the Premises which are not subject to Tenant's direct
            metering.


                  (b) From the date hereof throughout the Initial Term, the New
            Lease Term or the New Lease Renewal Term, until the occurrence of
            the date (the "New Electric Date") of the effective installation of
            Tenant's metering equipment and the transfer of direct access to
            electric energy by Tenant, Tenant shall continue to pay the Adjusted
            Electric Rent Inclusion Factor per annum, together with all
            subsequent adjustments thereto. In the event Tenant shall give
            notice of its election directly to meter its Premises (which notice
            shall specify those areas of the Premises to be metered), Landlord
            and Tenant shall cause an electrical survey to be undertaken by a
            professional surveyor mutually satisfactory to Landlord and Tenant
            and at their shared expense. The results of such survey, upon
            acceptance by both parties hereto, shall be utilized to establish
            calculation of Landlord's annual cost of electrical service supplied
            to any areas of each floor in the Premises which are not subject to
            Tenant's direct metering, as established by survey ("Landlord's
            Electric Factor").

                  In the Initial Term, upon the occurrence of the New Electric
            Date (i) Tenant shall pay to Landlord, monthly, as additional rent
            hereunder, an amount equal to one-twelfth of Landlord's Electric
            Factor, (ii) the fixed rent payable under the Lease shall be
            decreased on a per square foot basis (based on the current
            calculation of 481,924 for the rentable square footage of the
            Premises) by an amount equal to the then Adjusted Electric Rent
            Inclusion Factor, and (iii) Tenant shall have no further obligation
            to pay the Adjusted Electric Rent Inclusion Factor (other than such
            amounts as may be due in respect of the period prior to the New
            Electric Date).


                  In the New Lease Term (for any period subsequent to the New
            Electric Date), Tenant shall pay to Landlord, monthly, as additional
            rent hereunder, an amount equal to one-twelfth of (i) Landlord's
            Electric Factor and (ii) 50% of Tenant's Proportionate Share of the
            Applicable Common Area Electric Cost (as hereinafter defined).

                  As promptly as possible, Landlord and Tenant shall cause an
            electrical survey to be undertaken by a professional surveyor
            mutually satisfactory to Landlord and Tenant and at their shared
            expense. The results of such survey, upon acceptance by both parties
            hereto, shall be utilized to establish calculation of the annual
            cost, on a per square footage basis based on the square footage to
            take effect on the New Lease Commencement Date, in 1994 of
            electrical service supplied by Landlord to the common areas of the
            Building (the "Base Common Area Electric"). The "Applicable Common
            Area Electric Cost" for any Operational Year shall equal the sum of
            (1) the Base Common Area Electric and (2) the appropriate adjustment
            thereto to reflect (x) any material alteration or material addition
            to or reduction in the common area equipment and machinery, (y) any
            material increase or decrease of the usage of electricity in the
            common areas, and (z) any increase or decrease in Landlord's costs
            or expenses for, or in connection with, the furnishing by it of
            electricity to the common areas of the Building which shall be due
            to any change in the rates charged by the public utility or to any
            change in taxes based on the amounts charged by the public utility.

                  For purposes hereof, common area charges shall not include
            charges for electricity provided to vacant leaseable areas of the
            Building, or provided for the exclusive use of another occupant of
            the Building, or which are reimbursable by tenants as overtime
            charges, rent inclusion or otherwise.

                  Landlord shall furnish Tenant each Operational Year with a
            written detailed statement, in accordance with Section 26.05 (of the
            Reinstated Escalation Rent Clause, as defined in Paragraph 18
            hereof), showing the calculation of the Applicable Common Area
            Electric Cost, and Tenant shall have the right to dispute such
            statement in accordance with Section 26.07 (of the Reinstated
            Escalation Rent Clause, as defined in Paragraph 18 hereof). Landlord
            and Tenant shall have the right to resurvey from time to time in
            accordance with the provisions hereof.

                  (c) Effective as of the New Electric Date and for the
            remainder of the term of the Lease, Landlord covenants that it will
            not for itself, and will not permit any tenant in the Building, to
            "tap-in" or direct existing or increased electric capacity from the
            risers serving the Premises to any other premises or space.

                  (d) In the event Tenant's direct metering shall be installed
            in the Optional Space or any portion thereof, Tenant shall, if
            Tenant shall vacate such space pursuant to Section 11 hereof, pay
            the cost of reconnection of metering of such space to Landlord's
            meter(s).

            (ii) At the commencement of the New Lease Term, Article 24 shall be
deemed modified by the deletion of any and all references to a "Rent Inclusion
Factor" or "Adjusted Rent Inclusion Factor." Upon the occurrence of the New
Electric Date, Section 24.04. of the Lease shall be deemed modified by deleting
from the last line of said Section the words, "including a reasonable ampere
charge."

            (iii) Upon the occurrence of the New Electric Date, or if such date
shall not have occurred in the Initial Term, in the period of the New Lease
Term, Section 24.05 of the Lease shall be deemed deleted in its entirety and the
following provision shall be substituted in its place and stead:

            "Section 24.05. Tenant agrees to advise Landlord in writing of any
            material alteration or material addition to the electrical equipment
            or appliances in the Premises and any material change in the periods
            of use of the lighting fixtures and Tenant's business machines and
            equipment."


            8. Effective as of the date hereof and for the remainder of the term
of the Lease, Sections 25.01, 25.02 and 25.03 shall be deemed deleted and the
following provisions substituted in their place and stead:

            "Section 25.01. (a) Tenant shall have the right to sublet all
            or any portion of the Premises for such period of time (to end not
            later than one day prior to the New Lease Expiration Date, as the
            same may be extended pursuant to Article 38 hereof) and at such
            rental as Tenant may elect, and except as otherwise expressly set
            forth herein, subject to the provisions of this Article 25.

                  (b) Landlord covenants not to unreasonably withhold or delay
            its consent to a proposed subletting by Tenant of all or any portion
            of the Premises to the proposed subtenant on such terms as may be
            set forth in Tenant's notice to Landlord ("Tenant's Notice")
            requesting such consent, accompanied by a copy of the proposed
            sublease and any documents ancillary thereto. Within thirty (30)
            days of delivery of Tenant's Notice to Landlord, Landlord shall
            notify Tenant in writing of its decision regarding consent to the
            proposed subletting; provided, however, that Landlord shall not in
            any event be obligated to consent to any such proposed subletting
            unless:

                       (i) in the reasonable judgment of Landlord the proposed
                  subtenant is of a character and engaged in a business as are
                  in keeping with the standards of a first class office building
                  of comparable age and location;

                       (ii) in the reasonable judgment of Landlord the purposes
                  for which the proposed subtenant intends to use the portion of
                  the sublet premises are in keeping with the standards of a
                  first class office building of comparable age and location, it
                  being understood and agreed that any such written consent to a
                  subletting shall specify the purposes for which the subtenant
                  intends to use the sublet premises and the use of such
                  premises for such specified purposes shall not be deemed to be
                  a violation of this Lease;

                       (iii) such subletting will result in there being not more
                  than four occupants (including Tenant) per floor of the
                  Premises, except that there shall be no more than three
                  occupants (including Tenant) per floor on the eighteenth
                  (18th) and twenty-second (22nd) floors of the Premises and not
                  more than two occupants (including Tenant) on the twenty-fifth
                  (25th) floor of the Premises; notwithstanding any provisions
                  hereof to the contrary, any subdivision of a floor by Tenant
                  shall be made, at Tenant's expense, in compliance with
                  then-current applicable law, including, without limitation,
                  with respect to compartmentalization or sprinklering;

                       (iv) the space to be sublet shall be regular in shape, if
                  reasonable, with appropriate means of ingress and egress and
                  suitable for normal renting purposes;

                       (v) the proposed subtenant shall not be a government or
                  any subdivision or agency thereof nor then be a tenant or
                  subtenant of Landlord or an occupant of any part of the
                  Building;

                       (vi) Tenant shall reimburse Landlord for any reasonable
                  expenses that may be incurred by Landlord in connection with
                  said sublease, including, without limitation, the costs of
                  making reasonable investigations, if necessary, as to the
                  acceptability of a proposed subtenant and reasonable legal
                  expenses incurred in connection with the granting of any
                  requested consent to subletting (it being the intention of the
                  parties hereto that the calculation of Landlord's expenses
                  relating to this Article 25 shall be determined in a manner
                  consistent with the methodology utilized by Landlord and
                  Landlord's agent prior to the date hereof, provided that
                  notwithstanding the foregoing provisions, nothing herein
                  contained shall be deemed to deny to Landlord the right
                  reasonably to amend or modify such calculations or
                  methodology, from time to time, in conformity with
                  then-current industry standards, accounting practices or
                  tax-reporting or tax-rule procedures or under a Requirement of
                  Law. Landlord does not know of any such amendment or
                  modification to be made as of the date hereof;

                       (vii) in the event the subletting rental rate shall be
                  less than the rental rates then being charged under leases
                  being entered into by Landlord for comparable space in the
                  Building and for a comparable term, Tenant and any director,
                  officer or senior administrative personnel shall (a) not
                  publicly advertise (which restriction shall not apply to
                  private solicitations and broker listings but shall apply to
                  advertisement of the final terms of an executed sublease under
                  any and all circumstances) the economic terms of any proposed
                  sublease and (b) not disclose without the prior consent of
                  Landlord, unless required to disclose pursuant to any
                  Requirement of Law or court order, and shall keep
                  confidential, any such economic terms with respect to an
                  executed sublease and (c) require that the subtenant and real
                  estate broker(s), if any, agree to the same in writing;


                      (viii) such consent shall be evidenced by the delivery
                  of, and shall be subject to the covenants, agreements, terms,
                  provisions and conditions of, a "Consent to Sublease" duly
                  executed by Landlord, Tenant and the subtenant in the form
                  annexed hereto as Exhibit 25.01(b)(viii); and

                       (ix) Tenant and Landlord hereby agree that any subtenant
                  of Tenant shall have the one-time right, as to each particular
                  portion of such sublet premises, to assign the sublease or
                  under-sublet the space so sublet or any part thereof;
                  provided, however, that any such assignment or subletting
                  shall comply with the provisions of this Article 25 and
                  provided further that Landlord's consent to the subtenant's
                  assignment or sublet shall not constitute a waiver of the
                  requirement of obtaining Landlord's consent to any further
                  assignment or sublease.

            Within ten (10) Business Days after request by Tenant therefor,
Landlord shall deliver a non-disturbance, subordination and attornment agreement
(the "Landlord Non-Disturbance Agreement") to any subtenant that is occupying at
least 15,000 square feet (or at least one full floor of the Building, if less
than 15,000 square feet) of the Premises from Tenant in compliance with this
Lease. Landlord further agrees that to the extent that Landlord is required to
deliver a Landlord Non-Disturbance Agreement in favor of any subtenant of
Tenant, Landlord shall request and make a good faith, reasonable effort to
obtain, without cost to Landlord, from the holder of any ground lease or
mortgage covering the Building a similar form of non-disturbance agreement (the
"Lender Non-Disturbance Agreement") in favor of such subtenant. In the event a
cost shall be imposed by such ground lessor or lender as a condition of issuance
of such non-disturbance agreement, Landlord shall promptly so notify Tenant and
Tenant may elect, but shall not be so obligated, to pay such costs provided that
the Tenant's election not to pay such costs shall excuse Landlord from any
further obligation with respect to obtaining such non-disturbance agreement.
Tenant shall reimburse Landlord for all reasonable costs, including reasonable
attorneys' fees and disbursements, incurred by Landlord in preparing or
obtaining the documentation required by this paragraph, except with respect to a
lessor or mortgagee (exclusive of the trustee of Landlord on the date of
execution of this Agreement) which is an affiliate of Landlord.

                       All covenants, agreements, terms, provisions and
            conditions of any such "Consent to Sublease" so executed by
            Landlord, Tenant and the subtenant shall be 
            deemed to be covenants, agreements, terms, provisions and conditions
            of this Lease and the violation by Tenant or the subtenant of any
            covenant, agreement, term, provision or condition of such "Consent
            to Sublease" (other than a breach of the covenants set forth in
            (vii)(a) and (b) above by a party other than Tenant or any director,
            officer or senior administrative personnel of Tenant (it being
            understood that Tenant will make such a breach by the subtenant a
            default under the provisions of such sublease and shall diligently
            prosecute any breach of such provision)) shall entitle Landlord to
            all the rights and remedies provided for in this Lease or by law in
            the case of any violation of a covenant, agreement, term, provision
            or condition of this Lease.

            Section 25.02. Tenant shall be entitled to receive and retain
            all profits and proceeds under one or more subleases then in effect
            with respect to space in the Premises not in excess of 100,000
            square feet at any given time during the term of 
            the Lease. In the event Tenant shall enter into one or more
            subleases for space in the Premises such that the square footage of
            the subleases then in effect at any given point in time exceeds
            100,000, if the aggregate amount payable as rent (including as rent,
            without limitation, all amounts payable on account of changes in
            Taxes, operating costs, maintenance costs, labor rates or porters'
            wages, indexes or other formula contained in the sublease) with
            respect to any period of time by a subtenant under a sublease of any
            part of the Premises shall be in excess of the Tenant's Basic Cost
            (as hereinafter defined) for such part of the Premises, then,
            promptly after the collection by Tenant of such amounts so payable
            over such term under such sublease, Tenant will pay to the Landlord,
            as additional rent hereunder, an amount equal to 50% of the excess
            of such amounts so collected for such period over Tenant's Basic
            Cost for such part of the Premises, payable in monthly installments.
            The term "Tenant's Basic Cost," as used herein with respect to any 
            part of the Premises which is sublet, shall mean the cumulative sum

            not theretofore off-set against amounts so collected of (i) fixed
            rent at the Applicable Rental Rate (as hereinafter defined) for each
            square foot of the rentable area of such part of the Premises, (ii)
            the amount in additional rents or adjustments to rent (including as
            rent, without limitation, all amounts payable on account of changes
            in Taxes, operating costs, maintenance costs, labor rates or
            porter's wages, indexes or other formula contained in the sublease,
            and amounts payable in respect of the amortization of the cost of
            the Base Building Improvements) payable by Tenant to Landlord for
            such period with respect to such part of the Premises pursuant to
            Article 26 hereof (provided, however, that with respect to fixed
            rents and additional rents payable pursuant to clauses (i) and (ii)
            hereof in respect of any period of free rent or rent abatement under
            the sublease, such amounts shall be only the amounts, if any,
            applicable to such periods as a result of the amortization on a
            straight line basis over the term for which such part of the
            Premises is so sublet), (iii) the amount, if any, applicable to such
            period as a result of the amortization on a straight line basis over
            the term for which such part of the Premises is so sublet for any
            brokerage commissions; internal costs of funds allocation with
            respect to Tenant's reasonable and documented out-of-pocket
            expenses, including Tenant allowances and work letters, provided the
            same shall be expensed at then-applicable rates for Tenant's
            commercial paper (the "Applicable Rate"); reasonable legal fees and
            disbursements paid by Tenant and not reimbursed by the subtenant;
            commercially reasonable marketing and advertising fees and expenses;
            all costs paid to Landlord in connection with the execution of such
            sublease; the amount, if any, of any transfer tax, gains tax or
            other similar tax paid by Tenant as a result of such subletting
            provided the same is required to be paid by Tenant by operation of
            law and (iv) the amount, if any, applicable to such period as a
            result of the amortization on a straight line basis over the term
            for which such part of the Premises is so sublet of the cost of any
            so-called "tenant improvements" theretofore made by Tenant which are
            part of the Premises so sublet, and any actual and documented costs
            incurred by Tenant in making changes in the layout and finish of
            such part of the Premises (including, without limitation, reasonable
            architectural and engineering and demolition costs) in connection
            with such subletting, but only to the extent that such costs are not
            reimbursed by such subtenant through payments other than payments of
            fixed rent.


                  The term "Applicable Rental Rate" as used in this Article
            shall be deemed to mean $13.50 per square foot per annum during the
            period commencing on the date hereof and ending on June 30, 2000;
            $26.375 per square foot per annum during the period commencing on
            July 1, 2000 and expiring on June 30, 2005 and $31.00 per square
            foot per annum thereafter.

            Section 25.03. Except as Tenant is otherwise permitted herein
            so to do without the prior consent of Landlord, Tenant covenants and
            agrees, for Tenant and its successors, assigns and legal
            representatives, that neither this Lease nor the term and estate
            hereby granted, nor any part hereof or thereof, will be assigned,
            mortgaged, pledged, encumbered or otherwise transferred (whether
            voluntarily, involuntarily, by operation of law, or otherwise), and
            that neither the Premises, nor any part thereof (other than Tenant's
            personalty), will be encumbered in any manner by reason of any act
            or omission on the part of Tenant, or will be used or occupied, or
            utilized for desk space or for mailing privileges or as a
            concession, by anyone other than Tenant, its parent, 
            subsidiaries and affiliates, or their agents and affiliates for any
            purpose other than as hereinbefore set forth, or for which the
            Building or Premises are being used by Tenant at the time the Lease
            or this Second Supplemental Agreement is executed or at the time of
            any proposed sublease, without the prior written consent of Landlord
            in every case, provided, however, the assignment or transfer of this
            Lease, and the term and estate hereby granted, to any corporation
            into which Tenant is merged or with which Tenant is consolidated or
            to which all or substantially all of Tenant's assets are assigned or
            otherwise transferred, or any parent, subsidiary or affiliate
            thereof or of Tenant (such corporation being hereinafter in this
            Article 25 called "Related Entity") without the prior written
            consent of Landlord shall not be deemed to be prohibited hereby.
            Tenant may also sublease all or any portion of the Premises to a
            Related Entity without the consent of Landlord. Any assignment or
            subletting described above may only be made upon the express
            conditions that (1) Tenant shall promptly thereafter deliver to
            Landlord (a) an agreement executed by such assignee in form and
            substance reasonably satisfactory to Landlord whereby such assignee
            shall assume and agree to perform and to be jointly and severally
            bound by and upon, all the covenants, agreements, terms, provisions
            and conditions set forth in this Lease on the part of Tenant to be
            performed, and whereby such assignee shall expressly agree that the
            provisions of this Article 25 shall, notwithstanding such assignment
            or transfer, continue to be binding upon it with respect to all
            future assignments and transfers, or (b) a sublease agreement in
            form and substance reasonably satisfactory to Landlord, duly
            executed by Tenant and the subtenant, and (2) Landlord's consent to
            the assignment or sublet shall not constitute a waiver of the
            requirement of obtaining Landlord's consent to any further
            assignment or subletting."


            Furthermore, effective as of the date hereof, and for the remainder
of the term of the Lease, Section 25.06 shall be deemed modified by adding the
phrase, "and, provided, further, that so long as the Building directory is
maintained on a computerized basis, Landlord shall list all of the names of
Tenant that Tenant requests listed on the Building directory" following the
phrase "Lease by Tenant" in the sixth line of such Section.

            9. Effective as of the date hereof and for the remainder of the term
of the Lease, Article 32 is hereby modified by the addition of the following
provision:

            "Section 32.02. Landlord and Tenant shall, simultaneously with
            the execution of this Second Supplemental Agreement, join in the
            execution of a Supplemental Memorandum of Lease in proper form for
            recording in the Office of the City Register of the City of New
            York, County of New York, setting forth the existence of certain of
            the terms of this Second Supplemental Agreement, including the
            extension of the term of the Lease contained herein, and shall take
            such further action as may be necessary to effect such recording."


            10. Effective as of the New Lease Commencement Date and for the
remainder of the term of the Lease, the Lease is hereby modified by the addition
of Article 38, as follows:

                                   "Article 38

                                 OPTION TO RENEW

                 Section 38.01(a) So long as (x) Tenant shall not then be in
            default in the payment of fixed rent or in breach of any material
            provision of this Lease beyond any applicable period of grace (after
            notice, if any, required under this Lease), on the date of Tenant's
            Initial Notice (hereinafter defined) of exercise of the option
            herein contained and (y) on such date, Tenant or any subsidiary,

            "Renewal Option"), namely, for the period commencing on July 1, 2010
            and expiring on June 30, 2015 (the "New Lease Renewal Term") upon
            the following terms and conditions: (i) Such extensions and renewal
            to be subject to and upon all of the covenants, agreements, terms,
            provisions and conditions of this Lease, except that during the New
            Lease Renewal Term the fixed rent payable shall be equal to the sum
            which is 90% of the Fair Market Rental Value (as hereinafter
            defined) (the "Renewal Rent") determined in accordance with the
            provisions of this Article.

                  (ii) On or before January 1, 2009, Tenant shall notify
            Landlord whether it desires to proceed with a determination of the
            Renewal Rent as set forth herein with a view to extending the term
            of the Lease ("Tenant's Initial Notice"). The Renewal Option may be
            exercised with respect to either (i) the entire Premises or (ii)
            such portions of the Premises which comprise no less than 400,000
            contiguous (or, to the extent portions of such space are not then
            contiguous, the closest non-contiguous) rentable square feet of
            space in the Building then occupied by Tenant (the "Renewal Space").

                  (iii) On or before February 1, 2009, Landlord shall notify
            Tenant of the amount that Landlord estimates to be the "Fair Market
            Rental Value" and the Renewal Rent ("Rent Notice") of the Premises
            for such New Lease Renewal Term, assuming that such space is then
            free and clear of all leases and tenancies and is available in the
            then rental market for comparable first class office buildings in
            midtown Manhattan, taking into account all then relevant factors
            including, without limitation, giving effect to the relative credit
            worthiness of Tenant and the relative size of the premises demised
            to Tenant, adjustments for Landlord's then-customary workletter
            allowance, free rental concessions, and waiver of brokerage
            commissions and other cost-savings then applicable to commercial
            leases of the type and nature of this Lease (the "Fair Market Rental
            Value").


                  If Tenant does not dispute the Fair Market Rental Value and
            Renewal Rent set forth in the Rent Notice within thirty (30) days
            thereafter (as to which date time is of the essence), such Renewal
            Rent shall become the fixed rent for the New Lease Renewal Term. If
            Landlord shall fail timely to send a Rent Notice to Tenant, or if
            Tenant disputes the amount in Rent Notice, Tenant shall notify
            Landlord of Tenant's estimate of the Fair Market Rental Value and
            the Renewal Rent ("Tenant's Dispute Notice"). Upon Landlord's
            receipt of Tenant's determination, if Landlord accepts Tenant's
            determination, then Tenant's determination shall be the Renewal Rent
            for the Renewal Space. If Landlord and Tenant cannot agree on the
            Renewal Rent within twenty (20) days after the receipt of Tenant's
            Dispute Notice, during which time the parties may notify one another
            of modifications of their respective estimates of the Renewal Rent,
            then the fixed rent shall be determined by arbitration pursuant to
            the next paragraph hereof.

                  Notwithstanding the provisions of Article 29 of this Lease,
            the parties hereto shall attempt to agree on a single arbitrator
            (the "Referee"). The Referee must be a real estate broker licensed
            by the State of New York who is a member of the Real Estate Board of
            New York, Inc. (or a successor organization) and either a Senior
            Commercial Appraiser of the Society of Real Estate Appraisers or a
            member of the American Institute of Real Estate Appraisers (or a
            successor organization), and in any event with at least ten (10)
            years of experience in the leasing of office space in major office
            buildings in the Borough of Manhattan, in the City of New York. If
            the parties hereto cannot agree on the appointment of the Referee
            within fifteen (15) days after their failure to agree on the Renewal
            Rent, then the parties shall immediately thereafter request the
            American Arbitration Association ("AAA") or any successor
            organization to appoint a Referee meeting the foregoing
            requirements. If the AAA shall refuse to appoint such Referee or
            fail to do so within 10 days of the request, or if the AAA or any
            successor organization shall then no longer be in existence, either
            party hereto, on behalf of both, may apply to the Supreme Court in
            the County of New York for the appointment of such Referee, and the
            other party shall not raise any objection as to the Court's full
            power and jurisdiction to entertain the application and make such
            appointment. Within ten (10) days after the selection of the
            Referee, the parties shall submit to the Referee their respective
            last estimate of the Fair Market Rental Value and the Renewal Rent.
            During the twenty (20) days following the selection of the Referee,
            the parties may submit to the Referee such evidence as they may deem
            relevant. Within twenty (20) days following such twenty (20) day
            period, the Referee shall select one of the estimates to be the Fair
            Market Rental Value. The Referee's decision shall be final.

                  (iv) Within forty-five (45) days of the determination of the
            Renewal Rent, but in no event later than June 30, 2009, Tenant shall
            notify Landlord (the "Final Renewal Notice") whether it elects to
            renew the term of this Lease and if it so elects to renew the term
            of this Lease, upon receipt by Landlord of the Final Renewal Notice,
            this Lease shall be deemed renewed with respect to the portion of
            the Premises designated in Tenant's Initial Notice and Landlord and
            Tenant shall promptly execute and deliver an amendment to this Lease
            specifying the Renewal Rent and the term thereof.

                  Tenant shall have no further right to extend or renew the term
            hereof for any period subsequent to the expiration of the New Lease
            Renewal Term.

            11. Effective as of the date hereof and during the term of the Lease
expiring on the Term Expiration Date, the Lease is hereby modified by the 
addition of the following provisions:


                                   "Article 39


                                 OPTIONAL SPACE

                  Section 39.01. At any time, but only on a single date, Tenant
            may elect to extend the term of the Lease with respect to certain
            portions of up to 78,027 rentable square feet of the Premises (the
            "Optional Space") by giving to Landlord not less than twelve (12)
            months prior written notice on or before July 1, 1999 (which date
            shall be extended, if necessary, to the date which is ten (10) days
            after delivery to Tenant of a reminder notice of Tenant's option
            hereunder), provided, however, that the Optional Space which shall
            be the subject of such expansion shall be comprised of one or more
            full floors of space in the Building and shall consist of any
            combination of (a) the 17th, 18th, 22nd and 25th floors, (b) the
            17th, 18th and 22nd floors, (c) the 17th and 18th floors or (d) the
            17th floor.

                  Upon the timely exercise of the foregoing option with respect
            to the Optional Space, the term granted under the Lease (unless the
            same shall have expired sooner pursuant to any of the other
            conditions of limitation or provisions of this Lease or pursuant to
            law) shall be deemed extended from June 30, 2000 upon and subject to
            the covenants, agreements, terms, provisions and conditions of the
            Lease (and subject to the modifications thereof herein contained) so
            that said term shall expire on the New Lease Expiration Date or on
            such earlier date upon which said term (as so extended) may expire
            or be terminated pursuant to any of the conditions of limitation or
            other provisions of the Lease or pursuant to law, all (except as
            otherwise may be provided in this Second Supplemental Agreement)
            with the same force and effect as if said term (as so extended) were
            the term initially granted by the Lease but, unless herein otherwise
            expressly provided, nothing herein contained shall operate to extend
            the period for which the term of the Lease may be further renewed,
            or extended, pursuant to any option granted to Tenant thereby.

                  In the event Tenant shall not timely give notice of its
            election to extend the term of the Lease for the Optional Space,
            Tenant shall terminate its occupancy of the Optional Space not later
            than July 1, 2000 (as to which date time is of the essence). If
            Tenant shall not timely exercise its option with respect to the
            Optional Space, the option herein contained shall thereafter be void
            and of no further force and effect.

                  Upon Tenant's exercise of its option with respect to any
            portion of the Optional Space, or upon Tenant's failure to timely
            exercise such option, then, effective as of July 1, 2000, the fixed
            rent and additional rent and other charges hereunder shall be
            apportioned accordingly. Landlord and Tenant shall cooperate to
            complete and timely submit any and all returns and questionnaires
            relating to New York City and State real property transfer tax laws
            and any other applicable real property transfer or transfer gains
            tax laws (the taxes which are the subject of such laws are
            hereinafter collectively called "Transfer Taxes") in connection with
            any such option. The party upon whom such obligation to pay any
            Transfer Tax is imposed by law shall timely pay the appropriate
            Transfer Taxes and shall timely deliver evidence, reasonably
            acceptable to the other party, of such payment. Each party shall
            indemnify and hold the other party harmless from all losses,
            liabilities, interest, judgments, suits, demands, damages, costs and
            expenses (including reasonable attorneys' fees and disbursements
            incurred in the defense thereof) which may be incurred by reason of
            such party's failure to complete and timely submit any and all
            Transfer Tax returns and questionnaires and/or failure to timely pay
            any and all Transfer Taxes. The provisions of this paragraph shall
            survive the expiration of this Lease."


            12. Each party represents and warrants to the other party that
neither it nor any of its respective directors, officers, employees or agents
has acted so as to entitle any broker to a commission in connection with the
execution of this Second Supplemental Agreement or any of the transactions
contemplated hereby; provided, however, that the parties acknowledge that
Cushman & Wakefield, Inc., has acted as consultant to Landlord, and Goldman,
Sachs & Co. has acted as consultant to Tenant, and any compensation to be paid
to any such party shall be paid by its respective client pursuant to separate
agreements.

            Each party shall indemnify and hold the other party, and its
officers, directors, agents and employees harmless from and against all
liability, claims, suits, demands, judgments, costs, interest and expenses
(including reasonable counsel fees and disbursements incurred in the defense
thereof) to which the other party or any such officer, director, agent or
employee may be subject or suffer by reason of any claim made by any person,
firm or corporation for any commission, expense or other compensation as a
result of the execution and delivery of this Second Supplemental Agreement or
the exchange of the consideration provided herein if the aforementioned
representation and warranty of such party is inaccurate.

            13. (a)(i) Tenant acknowledges receipt of a certain report of Swanke
Hayden Connell/Edwards & Zuck entitled "Colgate Palmolive/300 Park Avenue/Lease
Attachment (the "Retrofit Report"), a copy of which is attached hereto as
Exhibit A and made a part hereof, which sets forth certain options to be made
available to Tenant with respect to proposed improvements to be undertaken by
Landlord related to, inter alia, the lobby, the elevators, the electrical, life
safety and heating, ventilation and air conditioning systems, restrooms and
roofs (the "Base Building Improvements") and "soft" costs including, without
limitation, fees for architects, engineers, special consultants and insurance
fees (collectively, the "Soft Costs"), together with all other proposed
improvements set forth in the Retrofit Report and related fees, costs and
charges, including, without limitation, documented fees and charges incurred by
Tenant either (a) prior to the date hereof, in the approximate sum of $80,000 or
(b) during the course of the Renovation Project in connection with the Base
Building Improvements. All such costs, fees and charges incurred by Tenant and
described in clauses (a) and (b) above (collectively, "Tenant Costs") shall be
reimbursed to Tenant on the closing of the Loan (as hereinafter defined). The
parties hereto acknowledge that the Retrofit Report provides 
outline specifications and performance criteria which broadly define the intent
of the parties with respect to the Base Building Improvements. The parties
further acknowledge that at the date of execution of this Second Supplemental
Agreement, based upon analysis of the Retrofit Report by both parties'
representatives, the reasonable estimated sum total of (a) the cost of the Base
Building Improvements, (including the Elevator Guaranteed Price and the
Guaranteed Price hereinafter defined), (b) the Soft Costs and (c) the Tenant
Costs, but excluding (1) the Costs of Financing (as hereinafter defined) and (2)
the Project Management Cost (as hereinafter defined), is in a range of not less
than $16,000,000 and not more than $18,000,000 (the "Improvements Sum"). In
addition to the foregoing, Landlord and Tenant have agreed to utilize a project
manager (the "Project Manager") in connection with Landlord's completion of the
Base Building Improvements. Landlord and Tenant agree that the selection for
project management services and the fees payable therefor (to the extent such
management fees or costs are not otherwise included as a normal Operating
Expense (the "Project Management Cost"), shall be competitively bid, shall not
exceed 3% of the Improvements Sum, and shall be governed in all respects by the
provisions hereof relating to the selection of the general contractor and other
project consultants. The parties hereto agree that the selection of the Project
Manager shall be completed prior to the date that the project architect,
engineers and other consultants shall begin their investigative work and design
relating to the Renovation Project.

            (ii) Landlord and Tenant acknowledge receipt of a schedule setting
forth each stage of the development and completion of the Base Building
Improvements captioned "300 Park Avenue Retrofit", prepared by Cushman &
Wakefield, Inc. (the "Approved Schedule"), and attached hereto as Exhibit B and
made a part hereof. Landlord and Tenant shall work diligently and shall
cooperate in all reasonable respects, in accordance with the provisions hereof,
to cause the Base Building Improvements to be completed in accordance with the
Approved Schedule.

            (b) Effective on the date hereof and throughout the term of this
Lease until the substantial completion of the Base Building Improvements,
Landlord shall have the right to conduct, in cooperation and consultation with
Tenant, and Tenant agrees to cooperate in all reasonable respects in connection
with any and all pre-design activities, building-system tests for field
conditions and any other investigations in and of the Premises and the Building
deemed necessary or useful by Landlord in connection with the 
renovation project (the "Renovation Project") contemplated hereunder and in the
Retrofit Report, provided that Landlord shall give reasonable prior notice to
Tenant and shall conduct all such activities, tests and investigations at
reasonable times and with reasonable efforts to minimize significant
interference in the operation of Tenant's business. Notwithstanding anything to
the contrary in this Section 13(b) contained, Landlord shall have completed all
building system and related tests required in connection with the Base Building
Improvements on or prior to October 21, 1996.


            (c) Tenant shall have the right, through one or more designated
representatives (but not more than two representatives shall be so designated at
any one time), to attend and receive periodic reports of such activities, tests
and investigations, to attend scheduled progress meetings (and promptly receive
copies of any minutes of such meetings), to request and obtain information from
Landlord from time to time with respect to the undertaking of the Base Building
Improvements and to receive, within five (5) business days of Landlord's
receipt, all pertinent third-party generated documentation, data, drawings and
reports in connection with the proposed Renovation Project, provided such right
shall be exercised by Tenant at all times in a commercially reasonable fashion,
and provided further that nothing herein contained shall be construed to afford
Tenant the right to receive or review any privileged or confidential internal
documentation generated (x) by Landlord with respect to its own business affairs
or with respect to its fiduciary duties to the Uris Trust or (y) between
Landlord and Cushman & Wakefield, Inc. in the latter's capacity as building
manager (except as provided in Section 26.08(b) of the Lease and Section 26.07
of the Reinstated Escalation Rent Clause, as defined in Paragraph 18 hereof).

            (d) (A) Landlord and Tenant hereby agree that (i) Swanke, Hayden
Connell shall be the architect on the Base Building Improvements, (ii) Edwards &
Zuck, P.C. shall be the mechanical and/or structural engineers thereon and (iii)
John A. Van Deusen & Associates shall be the consultant on the
elevator-renovation project. In the event that any of the parties listed above
or the project manager selected hereunder are dismissed or stop working on the
Base Building Improvements for any reason, within ten (10) days of such event,
Landlord shall submit in writing for Tenant's review and approval, in each
instance, the names of one or more proposed architects, mechanical and/or
structural engineers and any other consultants required to evaluate or design
the Base Building Improvements. Each submitted name shall be that of a competent
professional licensed in the State of New York, who shall, upon approval by
Tenant, be engaged solely by Landlord at Landlord's expense. In the event any
submission shall not be acceptable to Tenant in the exercise of its reasonable
judgment, Tenant shall so notify Landlord in writing within seven (7) days of
its receipt of Landlord's submission. Landlord shall promptly thereafter submit
alternate selections for Tenant's review and approval until such process shall
result in the selection of a replacement architect and/or engineer(s) acceptable
to both parties. Landlord and Tenant agree that only one set of architects,
engineers and other consultants shall be hired to work on the Renovation Project
and the selection of such firms shall be in accordance with the provisions
hereof.

            (B) Within ninety (90) days of the execution hereof, Landlord shall
submit in writing for Tenant's review and approval, in each instance, the names
of any other consultants in addition to those listed in Paragraph 13(d)(A)
hereto required to evaluate or design the Base Building Improvements. Each
submitted name shall be that of a competent professional licensed (if
applicable) in the State of New York who shall, upon approval by Tenant, be
engaged solely by Landlord at Landlord's expense. In the event any submission
shall not be acceptable to Tenant in the exercise of its reasonable judgment,
Tenant shall so notify Landlord in writing within seven (7) days of its receipt
of Landlord's submission. Landlord shall promptly thereafter submit alternate
selections for Tenant's review and approval until such process shall result in
the selection of an architect and/or engineer(s) acceptable to both parties. The
replacement of any such consultant shall be pursuant to the criteria set forth
in Paragraph 13(d)(A) hereof.

            (e) Tenant and Landlord covenant and agree to cooperate in reaching
an accord as to the scope, detail, and any other construction and fiscal details
with respect to the proposed renovations, if any, of the Building's lobby,
provided that the scope and detail thereof shall be substantially consistent
with the outline specifications set forth in the Retrofit Report. Tenant shall
have the exclusive right to determine the scope and detail of the other Base
Building Improvements (including elevator specifications), provided (i) the
scope and detail thereof shall be substantially consistent with the outline
specifications set forth in the Retrofit Report, (ii) such improvements shall in
no event include Building facade renovation of any type or nature, and (iii) the
proposed cost of the Base Building Improvements, exclusive of the lobby work
(giving effect to the actual and anticipated Soft Costs) shall not exceed the
sums budgeted therefor in the Retrofit Report as the Improvements Sum by more
than five percent (5%) (the "Maximum Permitted Amount"). Nothing herein
contained shall be construed to provide for more than $2,000,000 to be available
for lobby renovation work from the Improvements Sum. Tenant agrees to consult
with Landlord from time to time in the preparation of the design specifications.
Landlord and Tenant shall make a final determination of the scope and detail of
the renovations in the lobby at any time up to December 18, 1996. Tenant shall
(i) submit to Landlord its final determination of the scope and detail of the
elevator design specifications by written notice (the "Elevator Design Notice")
at any time from October 24, 1996 up to and including December 18, 1996 and (ii)
submit to Landlord its final determination of the scope and detail of the Base
Building Improvements (exclusive of the elevator specifications) by written
notice (the "Design Notice") at any time from December 4, 1996 up to and
including January 2, 1997.


            Within ten (10) days of the delivery of the Elevator Design Notice,
Landlord shall submit in writing for Tenant's review and approval, the names of
at least three candidates for the selection of the elevator contractor. Each
submitted name shall be that of a competent professional licensed in the State
of New York. In the event any submissions shall be unacceptable to Tenant in the
exercise of its reasonable judgment, Tenant shall so notify Landlord in writing
within five (5) business days of its receipt of Landlord's submission. Landlord
shall thereafter promptly submit an alternate selection for Tenant's review and
approval. Tenant shall have five (5) business days after receipt of the new
submission to approve the selection or notify Landlord of its objection, after
which Landlord shall submit a new selection.

            Not later than ten (10) days after Tenant's approval of the panel of
the elevator contractors, Landlord shall coordinate the completion of the
elevator renovation specifications substantially consistent with the Retrofit
Report and in accordance with the Approved Schedule, and solicit requests for
proposals from the selected panel of candidates for a guaranteed maximum price
(the "Elevator Guaranteed Price") for the renovation of the elevators. The
requests for proposal shall be subject to the agreement of Landlord and Tenant
as to scope, detail and any other construction and fiscal details customarily
contained therein and must be substantially consistent with the Retrofit Report.
Landlord shall make copies of the requests for proposal and the candidates'
responses immediately available to Tenant. Landlord and Tenant shall promptly
interview and negotiate pricing and other terms with the candidates (unless any
candidate's bid shall exceed a sum which is 15% in excess of the budgeted sum
for a Elevator Guaranteed Price in which event Landlord reserves the right to
remove the candidate from the selection panel), in consultation with Tenant.
Notwithstanding any provisions to the contrary herein contained, Landlord shall
be obligated to select as the elevator contractor the lowest qualified bidder
among the panel (which bid shall not exceed the anticipated sum in the Budget
allocated to the cost of the elevator work); provided, however, that Tenant may
select a higher bidder at its sole discretion, provided further, that such
selection does not result in the Maximum Permitted Amount being exceeded. In the
event none of the candidates' Elevator Guaranteed Prices are acceptable to
Landlord and Tenant, Landlord and Tenant agree to cooperate to obtain such
additional requests for proposal, or to make such modifications in the Retrofit
Report as may be necessary to reduce the costs of the elevator renovations to
fit within that portion of the Budget (hereinafter defined) proposed for
elevator renovations under the Retrofit Report.

            (f) On or prior to February 18, 1997, Landlord shall submit for
Tenant's review and approval a set of construction documents, including
pertinent specifications (collectively, the "Plans") and a schedule of each
stage of development and completion of the Base Building Improvements
substantially in conformance with the Approved Schedule. Tenant shall have
twenty (20) days after receipt in which to accept the Plans or offer such
changes as it may deem suitable provided such revisions shall be consistent with
the Retrofit Report. Landlord and Tenant, through their representatives, shall
meet as the parties deem necessary to reach written agreement as to the Plans on
or prior to May 8, 1997. The Plans shall designate all work which is required to
be performed by Landlord, including, without limitation, all work necessary so
that the lobby and elevators shall comply with all applicable laws, rules,
codes, regulations or ordinances including, without limitation, the applicable
provisions of the Americans with Disabilities Act and Local Law #58. Landlord
and Tenant agree to cooperate in the preparation and modification of the Plans
in the event of unforeseen field conditions so as to designate work, materials
or installation which (i) are practicable and, where adjustments due to field
conditions warrant, consistent with the physical conditions in the Building or
(ii) do not impair Landlord's ability to perform any of Landlord's obligations
under the provisions of this Lease or any typical landlord obligations under any
other lease of space in the Building.


            (g) Simultaneously with the delivery of the Plans, Landlord shall
submit to Tenant a proposed budget for the estimated line-item costs and
expenses of supplying and installing all of the items set forth on the Plans
(the "Budget"). Tenant shall submit its acceptance of the Budget or notice of
any proposed revisions to the Budget within fifteen (15) days next following the
submission by Landlord of the Budget. In the event Tenant shall have proposed
reasonable revisions thereto, Landlord shall incorporate such proposals as
Landlord deems feasible and reasonable in the exercise of its reasonable
judgment and resubmit a revised Budget for Tenant's review and approval within
ten (10) business days after receipt of Tenant's revisions. Tenant shall have
five (5) business days thereafter to accept the revised Budget or propose final
revisions in writing, which may be accepted or declined by Landlord in the
exercise of its reasonable discretion.

            (h) Simultaneously with the delivery of the Plans, Landlord shall
submit in writing for Tenant's review and approval, the names of at least three
candidates for the selection as general contractor. Each submitted name shall be
that of a competent professional licensed in the State of New York. In the event
any submissions shall be unacceptable to Tenant in the exercise of its
reasonable judgment, Tenant shall so notify Landlord in writing within ten
business days of its receipt of Landlord's submission. Landlord shall thereafter
promptly submit an alternate selection for Tenant's review and approval. Tenant
shall have ten business days after receipt of the new submission to approve the
selection or notify Landlord of its objection, after which Landlord shall submit
a new selection. Failure by Tenant to respond timely to a submission shall be
deemed acceptance thereof; provided, however, that the submission to Tenant
shall contain a reference to this Section 13 and the notice in bold lettering,
"Failure to respond within ten (10) business days shall be deemed acceptance by
Tenant of the enclosed submission."

            Not later than ten (10) business days after Tenant's approval of the
Plans, Landlord shall coordinate the completion of construction drawings
consistent with the Plans and in accordance with the Approved Schedule, and
solicit requests for proposals from the selected panel of candidates for a
guaranteed maximum price (the "Guaranteed Price") for the completion of the Base
Building Improvements. The requests for proposal shall be subject to the
agreement of Landlord and Tenant as to scope, detail and any other 
construction and fiscal details customarily contained therein substantially
consistent with the Plans and in accordance with the form of contract prepared
by Landlord, with Tenant's reasonable approval, on terms and conditions
customarily then-prevailing for projects of the type and nature herein
contemplated (the "Construction Contract"). Landlord shall 
make copies of the requests for proposal and the candidates' responses
immediately available to Tenant. Landlord and Tenant shall promptly interview
and negotiate pricing and other terms with the candidates (unless any
candidate's bid shall exceed a sum which is 15% in excess of the Improvements
Sum in which event Landlord reserves the right to remove the candidate from the
selection panel), in consultation with Tenant. On or prior to June 16, 1997,
Landlord and Tenant shall select the general contractor. Notwithstanding any
provisions to the contrary herein contained, Landlord shall be obligated to
select as the general contractor the lowest qualified bidder among the panel
(which bid shall not exceed the anticipated sum in the Budget allocated to the
cost of the applicable Base Building Improvements), provided however, that
Tenant may select a higher bidder at its sole discretion, provided further that
such selection does not result in the Maximum Permitted Amount being exceeded.
Except as expressly hereinafter set forth, Landlord shall have the sole and
exclusive obligation to pay the costs and expenses of construction of the Base
Building Improvements in excess of the agreed Guaranteed Price and the Elevator
Guaranteed Price. Promptly after selection of a general contractor, Landlord and
Tenant shall complete negotiation of the terms and conditions of a construction
contract (the "Construction Contract") with the general contractor, subject to
Tenant's consent, which shall not be unreasonably withheld or delayed, Landlord
shall execute an agreement on terms and conditions customarily then-prevailing
for projects of the type and nature herein contemplated.


            (i) Tenant may at any time, by written order, request changes to the
scope or detail of the Plans ("Tenant Change"), provided that any such change
does not (i) affect the cost of the Base Building Improvements (unless Tenant
shall pay the incremental cost thereof, as hereinafter set forth), (ii) increase
the time period for substantial completion by Landlord of the Base Building
Improvements (unless Tenant shall pay the incremental cost thereof, as
hereinafter set forth), and (iii) violate the provisions of any financing or
commitment for financing theretofore entered into in accordance with the
provisions of this Agreement. Prior to the commencement of any Tenant Change,
Landlord shall provide Tenant with written documentation which will show in
reasonable detail the cost of such Tenant Change and any delay in the completion
of the Base Building Improvements which may occur due to such Tenant Change. Not
later than ten (10) business days after Tenant's receipt of such documentation,
Tenant will notify Landlord of its decision of whether or not to proceed with
any such Tenant Change. All such increases in cost will be added to the amount
of the Loan (hereinafter defined) unless it is no longer possible to modify
without cost the terms of such Loan as a result of documents or a commitment
theretofore entered into in accordance with the provisions of this Agreement; in
which event either (i) such increases shall be added to the amount of the Loan,
if possible, at Tenant's option and at Tenant's sole cost and expense, or (ii)
upon written demand by Landlord, accompanied by reasonable documentation of such
increase, Tenant shall pay, as additional rent, the increase to Landlord within
thirty (30) days of demand (as to which date time shall be of the essence). If
any such change request causes an increase in the Guaranteed Price (whether
prior to or subsequent to the execution of a Construction Contract), Tenant
shall have the sole and exclusive obligation to pay the cost of such increase.
In the event Tenant's change request shall cause a delay in the time for
Landlord's performance in connection with the Base Building Improvements, Tenant
agrees to extend (1) Landlord's time for performance hereunder, and (2) the
period in which Tenant shall be obligated to bear the exclusive cost of
amortization of the Loan, by an equivalent number of days confirmed promptly in
writing.

            It is the understanding of Landlord and Tenant that any savings in
the Improvements Sum, whether due to a Tenant Change or otherwise, which arises
during the course of the completion of Base Building Improvements and which
cannot reasonably be applied to offset any trade line imbalances under the
Budget, will be passed on to Tenant and the amount of any such savings shall be
credited against the principal balance of the Loan (as hereinafter defined).

            Landlord covenants, warrants and represents that, prior to the
commencement of the Base Building Improvements, the Building and the building
systems shall, at Landlord's sole expense (other than such matters or violations
as are being corrected as part of the Base Building Improvements), be in full
compliance with all Requirements applicable to the Building, the building
systems and the Premises, including, without limitation, all building and fire
codes, zoning requirements, asbestos laws, Environmental Laws and the ADA; it
being the intention of the parties that Landlord shall be responsible (other
than such matters or violations as are being corrected as part of the Base
Building Improvements) for any violations which would impair or delay the
ability to obtain any permits or certificates of occupancy relating to the
Project.

            Landlord covenants that it shall use best efforts in connection with
the interview of a general contractor to propose and facilitate the solicitation
of women and minority bidders at each phase of the Renovation Project for which
the bidding process will take place.

            (j) Upon approval of the Budget, Landlord shall monitor the issuance
by the general contractor of the bid packages for major building systems in
accordance with the Approved Schedule. Landlord, as well as the general
contractor, shall have the right to add vendors/subcontractors to the bid list.
Tenant shall be advised promptly of the status and result of each phase of the
bidding process. With respect to the installation of elevators, electrical
wiring, and HVAC systems, Landlord will request that the general contractor
solicit bids from Tenant's proposed specialty vendors, provided (a) they are
approved by Landlord, whose approval shall not be unreasonably withheld or
delayed and (b) none of their selection will interfere or cause any conflict
with any other subcontractors, mechanics or laborers engaged in the
construction, maintenance or operation of the Building by Landlord.

            (k) All Alterations shall be made and performed substantially in
accordance with the Plans, all Requirements, and with industry standards for
first-class non-institutional office buildings in midtown Manhattan. All
materials and equipment to be incorporated in the Building or the Premises as a
result of the Base Building Improvements, or a part thereof, shall be of first
quality and shall be uniformly applied on the same standard of performance on a
building-wide basis. The Base Building Improvements shall constitute a single
non-recurring obligation on the part of Landlord, subject to Landlord's
enforcement of any warranties and other post-completion matters related to the
Base Building Improvements. In the event this Lease is renewed or extended for a
further term by agreement or by operation of law, Landlord's obligation to
perform and complete the Base Building Improvements shall not apply to any such
renewal or extension. Nothing herein contained shall be construed as a tenant
improvement allowance or landlord's workletter, and no such allowance or
workletter shall be provided during the term of this Lease or in any renewal
period.


            (l) The Base Building Improvements shall be substantially completed
on or prior to August 7, 1998. For purposes hereof, the "Date of Substantial
Completion" of the Base Building Improvements shall be the date certified by the
Renovation Project's architect when construction is sufficiently complete, in
accordance with the Plans, so that Tenant can occupy or use the Base Building
Improvements, and the elevators which service the Premises, for the use for
which each is intended, as expressed in the Plans. Landlord shall proceed with
all due diligence through final completion of the Base Building Improvements and
all work shall be in substantial conformance with Section 6.01 of the Lease.
Landlord's obligations timely to commence construction and to complete the Base
Building Improvements in accordance with the Approved Schedule shall be deemed
extended by the equivalent number of days in which Landlord is unable to
commence or complete construction due to inability to obtain materials, or
strikes or other labor disputes, fire or other casualty (or reasonable delays in
adjustment of insurance), accidents, orders or regulations of any Federal,
State, County or Municipal authority, or by any other cause beyond Landlord's
reasonable control (exclusive of any delays beyond 60 days which are related to
the Loan) (individually, an "Unavoidable Delay" and collectively, "Unavoidable
Delays"), whether or not such cause shall be similar in nature to those herein
before enumerated, or by reason of Tenant's change request(s). Landlord agrees
to make a good faith effort to provide timely written notice to Tenant of the
occurrence of an Unavoidable Delay. Upon request by Tenant, which request shall
not be made more frequently than on a quarterly basis, Landlord shall provide
Tenant with a written statement setting forth all Unavoidable Delays through the
date of such statement. In the event of any dispute between Landlord and Tenant
as to whether or not Landlord or Tenant is in default hereunder, such dispute
shall be determined by arbitration in accordance with the provisions of Article
29. Except as expressly provided in this Paragraph 13, nothing herein contained
shall be construed to grant Tenant the right, license or privilege to make or
perform any Base Building Improvements, except with Landlord's prior written
consent detailing such right, license or privilege. Tenant acknowledges that the
Base Building Improvements which it anticipates shall be proposed in the Design
Notice will necessitate extensive electrical and HVAC alterations throughout the
Building, as well as cessation of operations of one or more elevators from time
to time and for an indeterminate period; provided, however, that Tenant shall
receive prior written notice of such cessation of operations, offering good
faith estimates of the duration thereof and further providing that Landlord
shall work diligently and use diligent efforts (including the reasonable use of
overtime consistent with the Budget) to interfere as little as possible with
Tenant's use of, and access to, the Premises. At any time during the renovation
period and after substantial completion of the Base Building Improvements, Land-
lord may enter, where necessary, the Premises to complete, with reasonable
diligence, unfinished details of the Base Building Improvements. With respect to
any building systems (including elevators) that exclusively serve the Premises,
Landlord convenants, at Tenant's request, to make a good faith effort to
schedule or reschedule such interruption to a reasonably acceptable date after
the date proposed by Landlord and to conduct all scheduled suspensions of
services (including for routine maintenance, system upgrades, etc.) initiated by
Landlord outside of normal business hours. Cessation of, or interference with,
electrical or HVAC service (except with respect to the change-over to the new
electric and HVAC systems, which events shall occur during non-business hours),
or the cessation of operations of the elevators, or entry by Landlord, its
agents, servants, employees, contractors or other construction consultants in
the Premises for such purpose in substantial compliance with the provisions
hereof shall not constitute an actual or constructive eviction, in whole or in
part, or entitle Tenant to any abatement or diminution of rent or relieve Tenant
of any of its obligations under this Lease, or impose any liability upon
Landlord or its agents by reason of inconvenience or annoyance to Tenant, or
injury to or interruption of Tenant's business or otherwise. Landlord hereby
agrees to use best efforts to establish commercially reasonable schedules for
all of the aforementioned operations to minimize the interference with Tenant's
business operations. Notwithstanding the foregoing, nothing herein contained
shall be construed to obligate Landlord to take any action or fail to take any
action which would constitute a breach of any of its obligations to any other
tenants or subtenants occupying the Building during the renovation period (as
such obligations exist on the date hereof). Landlord represents and warrants
that it has no knowledge of any obligations to any tenant which would prohibit
the undertaking and completion of the Renovation Project.


            (m) Prior to commencement of the Base Building Improvements,
Landlord shall furnish to Tenant duplicate certificates of worker's compensation
(covering all persons to be employed by Landlord, and Landlord's contractors and
subcontractors in connection with the Base Building Improvements) and
comprehensive public liability (including property damage coverage) insurance
and such other insurance in form, with such companies, for such periods and in
such amounts as are commercially reasonable for a project of scope of the
Renovation Project, naming Tenant as an additional insured.

            (n) If Landlord, upon written notice by Tenant, fails diligently and
in good faith to undertake, fulfill and perform any material obligation under
this Agreement exclusively with respect to the Renovation Project within twenty
(20) business days after such written request (or, in the case of an emergency
which threatens the health or safety of people or material damage to property,
reasonably promptly under the circumstances; or, in the case of matters
affecting the access to, or use of, the Premises in such a manner as would
constitute a constructive eviction, within five (5) days after such written
request), Tenant may perform or have the work performed to provide the services
specified in such request, to the extent the request is consistent with the
Retrofit Report, the Plans or the Budget, as the case may be, and charge the
reasonable expense thereof to Landlord. Bills for the same shall be paid by
Landlord within ten (10) days after being submitted, and if not so paid, Tenant
may offset the amounts against any fixed rent or additional rent then due and/or
becoming due thereafter unless Landlord has disputed the need for such
performance by Tenant or the cost thereof, in which event there shall be no
right of offset until the matter has been determined by a single arbitrator
under the Expedited Procedures provisions of the Commercial Arbitration Rules of
the AAA (the "AAA Rules") (presently Sections 53 through 57 of the AAA Rules
and, to the extent applicable, Section 19 thereof); provided, however, that with
respect to any such arbitration: (i) the list of arbitrators referred to in Rule
54 shall be returned within ten (10) business days from the date of mailing;
(ii) the parties shall notify the AAA, by telephone, within four (4) business
days of any objections to the arbitrator appointed and will have no right to
object if the arbitrator so appointed was on the list submitted by the AAA and
was not objected to in accordance with the Rule 54; (iii) the Notice of Hearing
referred to in Rule 55 shall be four (4) business days in advance of the
hearing; and (iv) the hearing shall be held within seven (7) business days after
the appointment of the arbitrator.


            14. Subject to adjustment pursuant to Section 39.01 of the Lease,
for the period commencing on July 1, 2000 and expiring on June 30, 2005,
notwithstanding any provision of Article I of this Lease to the contrary, the
fixed rent reserved under this Lease for the Premises shall be, by reason of
such extension of the term of the Lease in the First Renewal Period, the sum of
FIFTEEN MILLION NINE HUNDRED FIFTY-TWO THOUSAND SEVEN HUNDRED SIXTY and 00/100
($15,952,760.00) DOLLARS per annum. For the period commencing on July 1, 2005
and expiring on June 30, 2010, the fixed rent reserved under this Lease for the
Premises shall be, by reason of such extension of the term of the Lease, the sum
of EIGHTEEN MILLION SEVEN HUNDRED FIFTY THOUSAND ONE HUNDRED SIXTY-FOUR and
00/100 ($18,750,164.00) DOLLARS per annum. In all instances, such rent shall be
payable during the New Lease Term in equal monthly installments in advance on
the first day of each month and every calendar month during such term, plus such
additional rent and other charges as shall become due and payable hereunder,
which additional rent and other charges shall be payable as provided in this
Lease, all to be paid to Landlord at its office, or such other place as Landlord
may designate.

            15. (a) Effective on the New Lease Term Commencement Date and during
the remaining term of the Lease, Section 35.01 shall be deemed modified by
deleting the figure "two hundred thousand (200,000) square feet" and
substituting the figure "three hundred fifty thousand (350,000) square feet" in
its place and stead.

            (b)  Effective as of the date hereof and for the
remainder of the Lease, the Lease is hereby modified by the
addition of Section 35.06, as follows:

            "Section 35.06. In the event that Tenant and its subsidiaries,
affiliates and parent lease either (i) at least two hundred thousand (200,000)
square feet of rentable square feet in the Building and which premises shall be
Tenant's national or international headquarters, or (ii) at least the same as,
or more, rentable square feet in the Building (under square footage calculations
in effect with respect to this Lease on the date of execution of the Second
Supplemental Agreement) than any other tenant in the Building (all of conditions
(i) and (ii) collectively, the "Signage Conditions"), Landlord shall keep in
place and maintain, at Landlord's expense (provided that Tenant shall be
responsible for any repair), during the term of this lease, on a non-exclusive
basis, Tenant's signs (or signage of comparable size, location and quality)
currently in place on the facade of the Building (on the north and south sides
of the Park Avenue entrance) on the date hereof. Provided the Signage Conditions
shall have been met, the signage of no other tenant shall appear above Tenant's
signage or be of a larger size. Tenant expressly agrees that the privileges of
this Section 35.06 are granted by Landlord to Tenant and to its 
Related Entity exclusively, and no other assignee or subtenant, or further
assignee or subtenant thereof, shall have the right to claim benefit of the
privileges in this Section contained."

            16. (a) Landlord has advised Tenant that Landlord expects to seek
construction loan financing (the "Loan") sufficient to cover (i) the undertaking
of the Improvements Sum, (ii) the Project Management Cost and (iii) the Costs of
Financing (as hereinafter defined). Landlord has advised Tenant that
simultaneously with securing the Loan, Landlord shall endeavor to obtain a
commitment for the refinancing of an existing loan on the Building and for the
costs of Tenant improvements proposed for the balance of the Building not leased
to Tenant (the "Additional Loan"). Landlord reserves the exclusive right to
solicit and select suitable financing arrangements for the Loan, on terms and
conditions and from a source (or sources) satisfactory to Landlord provided that
the Loan will be (X) an arm's-length transaction, with an institutional lender
on conventional terms in the marketplace for loans of the type and nature of the
Loan as contemplated hereunder, (y) self-liquidating over a term of maturity
equivalent to the remainder of the term of the Lease, and (z) with respect to
the aggregate of the Loan and the Additional Loan, in the aggregate will not
exceed 50% of the value of the Building. The Loan will be obtained in an amount
sufficient to cover (1) the Improvements Sum, (2) the Project Management Cost;
(3) any and all costs directly related to obtaining or facilitating the Loan,
including lender's due diligence costs and expenses; commitment or other
origination fees; closing and/or recording charges, mortgage taxes and fees, if
any; title insurance and related charges, if any, and reasonable counsel fees
and disbursements of the lender and Landlord related to the Loan, and (4) the
interest-carry cost in the period starting from the first draw down which
relates to the Base Building Improvements (including the drawdown for fees to be
paid in connection with the Loan) through the Date of Substantial Completion
(less any period for which Landlord has caused a delay which is not permitted
hereunder as an Unavoidable Delay) (all of the items described in clause (3) and



(4), collectively, the "Costs of Financing"). In no event shall Tenant be
required to reimburse Landlord for any of its "out-of-pocket" or other expenses
related to the financing other than on an amortized basis pursuant to Section
16.(b). Landlord shall be responsible for, and shall indemnify and hold Tenant
harmless from, the payment of (i) the principal and interest of all amounts in
excess of the aggregate of the Improvements Sum, the Project Management Cost and
the Costs of Financing, as such amounts are certified, to the best of their
knowledge, by Landlord and the Renovation Project's architect (as set forth in
Section 16(b) hereof), and (ii) any amounts financed by Landlord including,
without limitation, the Additional Loan, in excess of the Loan, (iii) all costs
directly related to, and the allocable share of all general costs related to,
the financing of such excess amounts and (iv) any incremental cost to any of the
foregoing resulting from the financing of such excess amounts. Landlord agrees
to deliver to Tenant copies of all term sheets, commitments and proposed
documentation from prospective financing sources promptly upon Landlord's
receipt of same. Landlord covenants to permit Tenant a reasonable opportunity to
review the terms of such financing prior to execution of a commitment letter.
Landlord agrees to deliver to Tenant a true and complete copy of all major
documentation evidencing the Loan promptly after closing, together with
reasonable substantiation of all Costs of Financing.

            (b) Effective on the Date of Substantial Completion of the Base
Building Improvements and for the remainder of the period commencing on that
date and expiring on the Term Expiration Date, Tenant agrees to pay in full, as
additional rent hereunder, together with Tenant's monthly installment of fixed
rent (accompanied by the lender's payment notices issued to Landlord), the
monthly installments of principal indebtedness due and payable under the Loan,
together with interest accrued thereon (collectively, the "Tenant's Loan
Payment"), on an amortization schedule sufficient to repay the principal
indebtedness on the Loan on the date immediately preceding June 30, 2010. Within
ten (10) Business Days after the Date of Substantial Completion, Landlord and
the Renovation Project's architect shall certify, to their best knowledge, to
Tenant the actual amounts incurred as the Improvements Sum (exclusive of any
costs as to which Landlord or Tenant are unilaterally obligated to pay for in
accordance with the provisions hereof), the Project Management Cost and the
Costs of Financing. In the event the final installment of the Tenant's Loan
Payment shall be due and payable on a date other than the Term Expiration Date,
such payment shall be prorated for the period commencing on the immediately
preceding payment date and expiring on the Term Expiration Date.

            (c) Effective on the New Lease Commencement Date and expiring on
June 30, 2010, Tenant agrees to pay, as additional rent hereunder, together with
Tenant's monthly installment of fixed rent (accompanied by such lender's payment
notices as described in the immediately preceding paragraph) the Tenant Share
(hereinafter defined) of Landlord's total monthly payments of principal and
interest (and penalties, if any shall be incurred by Landlord due to Tenant's
failure timely to make any prior Tenant's Loan Payment to Landlord), due and
payable on the Loan. For purposes of this paragraph, the term "Tenant Share"
shall be deemed to mean the percentage which is the quotient of the division of
(x) the rentable square footage of the Premises as of the New Lease Commencement
Date by (x) 717,370.


            In addition to the foregoing, Tenant also agrees to pay to Landlord,
to the extent not included in the Tenant Share of Landlord's monthly payment, a
sum (the "Accrued Interest") equal to the amount of interest accrued and unpaid
on the Loan for the period commencing on the first draw down relating to the
Base Building Improvements through the Date of Substantial Completion (less any
period for which Landlord has caused a delay which is not permitted hereunder as
an Unavoidable Delay). The Accrued Interest shall be paid to Landlord, in equal
monthly installments together with Tenant's monthly installment of Fixed Rent
each month following completion of construction and in each month thereafter
until paid in full, on an amortization schedule sufficient to repay the Accrued
Interest on June 30, 2010.

            (d) Landlord and Tenant agree mutually to cooperate to confirm in
writing dates of payment and the calculation of payments of the Tenant Share and
installment payments of Accrued Interest as these dates and amounts shall be
determinable following the closing of the Loan, the completion of Base Building
Improvements and the final documentation of calculation of the Accrued Sum, as
the case may be.

            17.   Effective as of the New Lease Commencement
Date and for the remainder of the term of the Lease:

            (a) Exhibit G, "Building Square Footage", is deemed deleted, and
Exhibit G-1, "Revised Building Square Footage," attached hereto, shall be
substituted in its place and stead, and any references in the Lease to "Exhibit
G" shall hereafter be deemed to refer to "Exhibit G-1."

            (b) Section 26.01.B. is deemed deleted and the
following shall be substituted in its place and stead:

            "B. Subject to adjustment pursuant to Section 39.01 of the
            Lease, for purposes of this Lease, the Premises shall be deemed to
            be 604,844 rentable square feet, and the Building above grade shall
            be deemed to be 717,370 rentable square feet, per Exhibit G-1, and
            Tenant's Proportionate Share shall be deemed to be 84.314% for the
            Premises. Such calculations have been agreed to by the parties and
            shall be binding on the parties hereto."

            (c) Section 26.02(c) shall be deemed modified by the addition of the
phrase "(including Tenant's Proportionate Share of the Base Building
Improvements") following the phrase "made for Tenant" in the penultimate line of
such section.

            18. Effective as of the New Lease Commencement Date and for the
remainder of the term of the Lease, (a) current Sections 26.04 through 26.08
shall be deleted from the Lease, and Sections 26.04 through 26.08 from the
original form of Lease dated August 15, 1978, between Landlord and Tenant
("Reinstated Escalation Rent Clause") shall be reinstated in their place and
stead, provided that the term "Base Year" shall be deemed to be amended to be
the calendar year 1994.

            (b) In connection with the reinstatement of the Reinstated
Escalation Rent Clause, Landlord agrees to grant Tenant reasonable access to
Landlord's books and records for the purpose of verifying Operating Expenses
incurred by Landlord, and to have and make copies of any and all bills and
vouchers relating thereto, subject to reimbursement by Tenant, pertaining to the
period from January 1, 1994 through the New Lease Commencement Date.

            (c) Notwithstanding anything to the contrary provided herein,
Operating Expenses, as calculated for the Base Year and for each Operational
Year, shall exclude (i) Landlord's Electric Factor, (ii) any costs for, or in
connection with, the furnishing of electricity to common areas of the Building,
and (iii) any costs for, or in connection with, the furnishing of services
provided by the cleaning contractor.

            (d) In all events whether or not Tenant shall elect to assume
certain services provided by the cleaning contractor pursuant to Section 17.02,
Tenant shall continue to be obligated to pay for window cleaning services and
the Tenant's Proportionate Share of common area charges for such services which
shall be charged separately from other Operating Expenses, provided that Tenant
shall not pay more for such common area and window cleaning services than if
Tenant were to pay the Tenant's Proportionate Share of such charges as an
Operating Expense. Landlord shall charge for such services and Tenant shall pay
the Tenant's Proportionate Share of expenses for such services in accordance
with the provisions of Article 26.



            19. Effective as of the New Lease Commencement Date and for the
remainder of the term of the Lease, the term "Base Tax" shall be modified so as
to be deemed to mean the Taxes for the Tax Year commencing on July 1, 1994 and
ending on June 30, 1995.

            20. This Second Supplemental Agreement is subject to (a) the receipt
by Landlord of the approval for this Agreement and (b) the receipt by Tenant of
a Lender Non-Disturbance Agreement on the Lender's standard form and on terms
and conditions typically offered by such Lender in similar commercial
transactions and on terms and conditions substantially in accordance with
applicable provisions of the Lease, in each instance from the holder of the
current first mortgage covering the Building (the "Lender"). Landlord covenants
promptly to submit this Second Supplemental Agreement for its mortgagee's
approval and to request a Lender Non-Disturbance Agreement from such mortgagee
and to cooperate with its mortgagee in responding to reasonable requests for
information with respect hereto. Landlord shall give prompt notice to Tenant of
its receipt of any such approval or disapproval, as the case may be. If such
approval is not obtained or is denied within thirty (30) days after the date
hereof, or if the Lender Non-Disturbance Agreement shall not be received by
Tenant within sixty (60) days after the date hereof, then upon five (5) days
written notice from Tenant, this Second Supplemental Agreement shall be void and
without any force or effect.

            21. This Second Supplemental Agreement shall be construed without
regard to any presumption or other rule requiring construction against the party
causing this Second Supplemental Agreement to be drafted.

            22. This Second Supplemental Agreement is executed by The Bank of
New York (successor to Irving Trust Company), Trustee under the Will of Harold
D. Uris, Deceased, not personally but solely as Trustee, as aforesaid, in the
exercise of the power and authority conferred upon and vested in it as such
Trustee. All the terms, provisions, stipulations, covenants and conditions to be
performed by The Bank of New York (successor to Irving Trust Company) are
undertaken by it solely as Trustee as aforesaid, and not individually and all
statements herein made are made on information and belief and are to be
construed accordingly, and no personal liability shall be asserted or be
enforceable against The Bank of New York (successor to Irving Trust Company) by
reason of any of the terms, provisions, stipulations, covenants and/or
statements contained in this Second Supplemental Agreement.

            23.   Except as modified hereby, the terms and
provisions of the Lease are ratified and confirmed.

            IN WITNESS WHEREOF, the parties hereto have executed this Second
Supplemental Agreement as of this 15th day of March, 1995 to be effective as of
the day and year first above written.



                                                THE BANK OF NEW YORK,
                                                Trustee under the Last Will and
