                                OPTION AGREEMENT

                  OPTION AGREEMENT dated February 21, 1998, between ACTV, Inc.,
a Delaware corporation (the "Corporation") and David Reese (the "Employee").

                  The Corporation desires to grant to the Employee the right and
option to purchase up to 856,000 shares (the "Option Shares") of Common Stock
(the "Common Stock"), of the Corporation, on the terms and subject to the
conditions hereinafter set forth.

                  NOW, THEREFORE, in consideration of the receipt of $1.00 and
other good and valuable consideration, the receipt of which is hereby
acknowledged, the parties hereby agree as follows:

                  SECTION 1. OPTION TO PURCHASE COMMON STOCK.

                           a. Subject to Section 5 hereof, the Corporation
hereby grants to the Employee an option (the "Option") to purchase from the
Corporation 856,000 Option Shares, at a purchase price of $1.60 per Option Share
(the "Option Price"). The Employee's right and option to purchase the Option
Shares shall vest annually commencing January 1, 2000 until January 1, 2002,
with respect to installments of 285,334 in 2000 and 285,333 in 2001 and 2002
Option Shares at the Option Price, so long as the Employee is employed by the
Corporation. Said right shall be cumulative so that as of January 1, 2002,
Optionee shall have the fully vested right to purchase 856,000 Option Shares. In
the event that the Employee's employment with the Corporation terminates prior
to January 1 of 2001 and 2002, the Employee shall not have the right or option
to purchase any part of the installment of 285,333 Option Shares that would have
otherwise vested on such January 1. With respect to the Option, the "Option
Period" shall commence on the date hereof and terminate on December 31, 2006.

                           b. The Option may be exercised by the Employee by
delivery to the Corporation, at any time commencing one year from the date
hereof, of a written notice (the "Option Notice"), which Option Notice shall
state the Employee's intention to exercise the Option, the date on which the
Employee proposes to purchase the Option Shares (the "Closing Date") and the
number of Option Shares to be purchased on the Closing Date, which Closing Date
shall be no later than 30 days nor earlier than 10 days following the date of
the Option Notice. Upon receipt by the Corporation of an Option Notice from the
Employee, the Employee shall be obligated to purchase that number of Option
Shares to be purchased on the Closing Date set forth in the Option Notice.

                           c. The purchase and sale of Option Shares acquired
pursuant to the terms of this Option Agreement shall be made on the Closing Date
at the offices of the Corporation. Delivery of the Stock certificate or other
instrument registered in the name of the Employee, evidencing the Option Shares
being purchased on the Closing

<PAGE>

Date, shall be made by the Corporation to the holder of this Option on the
Closing Date against the delivery to the Corporation of a check in the full
amount of the aggregate purchase price therefor.

                  SECTION 2. REPRESENTATIONS AND WARRANTIES OF THE HOLDER. The
Employee hereby represents and warrants to the Corporation that in the event the
Employee acquires any Option Shares, such Option Shares will be acquired for his
own account, for investment and not with a view to the distribution thereof. The
Employee understands that except as set forth in Section 6 hereof, the Option
Shares will not be registered under the Securities Act of 1933, as amended (the
"Securities Act"), by reason of their issuance in a transaction exempt from the
registration requirements of the Securities Act pursuant to Section 4 (2)
thereof and that they must be held indefinitely unless a subsequent disposition
thereof is registered under the Securities Act or the transaction is except from
registration.

                  SECTION 3. REORGANIZATION; MERGERS; SALES; ETC. If, at any
time during the Option Period, there shall be any capital reorganization,
reclassification of Common Stock (other than a change in par value or from par
value to nor par value or from no par value to par value or as a result of a
stock dividend or subdivision, split-up or combination of shares), the
consolidation or merger of the Corporation with or into another corporation or
of the sale of all or substantially all the properties and assets of the
Corporation as an entirety to any other corporation or person, the unexercised
and fully vested portion of this Option shall, after such reorganization,
reclassification, consolidation, merger or sale, be exercisable for the kind and
number of shares of stock or other securities or property of the Corporation or
of the corporation resulting from such consolidation or surviving such merger or
to which such properties and assets shall have been sold to which the Employee
would have been entitled if the Employee had held shares of Common Stock
issuable upon the exercise hereof immediately prior to such reorganization,
reclassification, consolidation, merger or sale. The provisions of this Section
3 shall similarly apply to successive reorganizations, reclassifications,
consolidations, mergers and sales.

                  SECTION 4. ADJUSTMENT OF OPTION SHARES AND OPTION PRICE.

                           a. The number of Option Shares subject to this Option
during the Option Period shall be cumulative as to all prior dates of
calculation and shall be adjusted for any stock dividend, subdivision, split-up
or combination of Common Stock.

                           b. If, at any time through December 31, 2001 of the
Option Period, the Corporation issues any previously unissued Common Stock over
and beyond the number shares outstanding February 21, 1998, then the number of
shares subject to the Option shall be adjusted such that the holder thereof
shall have the right to exercise the Option for the same percentage of the
issued and outstanding Common Stock of the

<PAGE>

Corporation as he held option shares on February 21, 1998.

                           c. The Option Price shall be subject to adjustment
from time to time as follows:

                               (1) If, at any time during the Option Period, the
number of shares of Common Stock outstanding is increased by a stock dividend
payable in shares of Common Stock or by a subdivision or split-up of shares of
Common Stock, then, immediately following the record date fixed for the
determination of holders of shares of Common Stock entitled to receive such
stock dividend, subdivision or split-up, the Option Price shall be appropriately
decreased so that the number of shares of Common Stock issuable upon the
exercise hereof shall be increased in proportion to such increase in outstanding
shares.

                               (2) If, at any time during the Option Period, the
number of shares of Common Stock outstanding is decreased by a combination of
outstanding shares of Common Stock, then, immediately following the record date
for such combination, the Option Price shall be appropriately increased so that
the number of shares of Common Stock issuable upon the exercise hereof shall be
decreased in proportion to such decrease in outstanding shares.

                  SECTION 5. TERMINATION OF THE OPTIONS.

                           a. TERMINATION OF OPTIONS IN GENERAL. Subject to
subsections (b) - (c) of this Section, the Option granted hereby shall terminate
and the Option shall no longer be exercisable after the earlier of December 31,
2006 or one year after the date of termination of employment, except in the case
of death or disability.

                           b. OPTION RIGHTS UPON DISABILITY. If an Employee
becomes disabled while employed by the Corporation or any affiliate or
subsidiary, the Board of Directors or the Stock Option Committee of the
Corporation, will allow the Option to be fully exercised, to the extent that the
Employee was entitled to exercise the Option at the date of his disability.

                           c. DEATH OF THE OPTIONEE. In the event that an
Employee shall die while he is an employee of the Corporation and prior to his
complete exercise of the Option, the Option may be exercised in whole or in part
only: (i) by the Employee's estate or on behalf of such person or persons to
whom the Employee's rights pass under his Will or by the laws of descent and
distribution, (ii) to the extent that the Employee was entitled to exercise the
Option at the date of his death, and (iii) prior to the expiration of the term
of the Option.

                  SECTION 6. PIGGYBACK REGISTRATION.

                           a. If, at any time commencing January 1, 2000 and
expiring December 31, 2006, the Corporation proposes to register any of its
securities under the Securities Act (other than in connection with a merger or
pursuant to Form S-8 or other comparable Form) it will give written notice by
registered mail, at least thirty (30) days prior to the filing of such
registration statement, to the Employee of its intention to do so. If the
Employee notifies the Corporation within ten (10) days after receipt of any such
notice of his desire to include any Option Shares, owned by him (on a fully
vested basis) in such proposed registration statement, the Corporation shall
afford the Employee the opportunity to have any of his Option Shares registered
under such registration statement, the Corporation shall afford the Employee the
opportunity to have any of his Option Shares registered under such registration
statement; provided that (i) such inclusion does not pose any significant legal
problem and (ii) if such registration statement is filed pursuant to an
underwritten public offering, the underwriter approves such inclusion.

                           b. Notwithstanding the provisions of this Section 6,
the Corporation shall have the right at any time after it shall have given
written notice pursuant to this Section 6 (irrespective of whether a written
request for inclusion of any Option Shares shall have been made) to elect not to
file any such proposed registration statement, or to withdraw the same after the
filing but prior to the effective date thereof.

                           c. Employee will cooperate with the Corporation in
all respects in connection with this Agreement, including, timely supplying all
information reasonably requested by the Corporation and executing and returning
all documents reasonably requested in connection with the registration and sale
of the Option Shares. In addition, Employee will comply with all applicable
provisions of state and federal securities laws, including rule 10b-6 and will
not, during the course of a distribution, purchase any of the securities being
distributed.

                           d. All expenses incurred in any registration of the
Option Shares under this Agreement shall be paid by the Corporation, including,
without limitation, printing expenses, fees and disbursements of counsel for the
Corporation, expenses of any audits to which the Corporation shall agree or
which shall be necessary to comply with governmental requirements in connection
with any such registration, all registration and filing fees for the Option
Shares under federal and state securities laws, and expenses of complying with
the securities or blue sky laws of any jurisdictions; provided, however, the
Corporation shall not be liable for (a) any discounts or commissions to any
underwriter; (b) any stock transfer taxes incurred with respect to Option Shares
sold in the offering or (c) the fees and expenses of counsel for Employee,
provided that the Corporation will pay, the costs and expenses of Employee's
counsel when the Corporation's counsel is representing all selling security
holders.

            LEASE (this "Lease"), dated as of December 1, 1999, between 225
FOURTH, LLC ("Landlord"), a Delaware limited liability company whose address is
c/o Orda Management Corporation, 225 Park Avenue South, New York, New York 10003
and ACTV, Inc. ("Tenant"), a Delaware corporation whose address is 1270 Sixth
Avenue, New York, New York prior to the commencement of the Term, and thereafter
Tenant's address shall be that of the Building.

                              W I T N E S S E T H

            WHEREAS, Landlord is willing to lease to Tenant and Tenant is
willing to hire from Landlord, on the terms hereinafter set forth, certain space
in the office building located at Block 874, Lot 1 in New York, New York and
commonly known as 225 Park Avenue South, New York, New York (the "Building A")
and in the office building located at Block 874, Lot 4 in New York, New York and
commonly known as 233 Park Avenue South (the "Building B"; collectively Building
A and Building B are referred to as the "Building") on the land more
particularly described in Exhibit A (the "Land"; the Land and the Buildings and
all plazas, sidewalks and curbs adjacent thereto are collectively called the
"Project").

            NOW, THEREFORE, Landlord and Tenant agree as follows:

                                   ARTICLE 1

                              Premises; Term; Use

            1.01 Demise. (a) Landlord hereby leases to Tenant and Tenant hereby
hires from Landlord, subject to the terms and conditions of this Lease, the
entire 19th floor (the "19th Floor") and the 19th Floor Mezzanine (the "19th
Floor Mezzanine"; together with the 19th Floor, the "Original Premises" or the
"Premises") substantially as shown on the plan annexed as Exhibit B. Landlord
and Tenant agree that the 19th Floor is conclusively deemed to contain 19,713
rentable square feet; the 19th Floor Mezzanine is conclusively deemed to contain
2,022 square feet; and the Original Premises is conclusively deemed to contain
21,735 rentable square feet.

            (b) Tenant acknowledges that the 19th Floor Mezzanine shall be
demised as storage space; provided, however, that if Tenant, at Tenant's cost
and expense, obtains a Certificate of Occupancy for the 19th Floor Mezzanine for
a use other than storage space, and Tenant, at Tenant's cost and expense, brings
the 19th Floor Mezzanine into compliance with any and all applicable Laws
(hereinafter defined), including, without limitation, ADA (hereinafter defined),
then Landlord shall permit Tenant to use the 19th Floor Mezzanine for any use
that is lawfully permitted under the amended Certificate of Occupancy. Any
representations and warranties made by Landlord in this Lease shall not apply to
the 19th Floor Mezzanine. Tenant shall have the exclusive right to use the
staircase located within the Premises for access from the 19th Floor to the 19th
Floor Mezzanine.

            (c) Landlord shall provide Tenant with temporary office space, as
set forth in Section 1.06(a) herein, until the Possession Date.

                                      -1-

<PAGE>

            1.02 Term. (a) The term of this Lease (the "Term") shall commence on
the Possession Date and shall end, unless sooner terminated as herein provided,
on the last day of the calendar month in which occurs the fifteenth (15)
anniversary of the Rent Commencement Date (such date, as the same may be
extended pursuant to Article 9, is called the "Expiration Date").

            (b) Landlord represents to Tenant that, as of the date of this
Lease, the Original Premises are subject to a lease agreement with the City
University of New York, and Tenant acknowledges that this Lease shall not be
effective with respect to the Original Premises (as opposed to First Temporary
Space and Second Temporary Space) unless and until Landlord receives a signed
termination agreement, approved by all necessary parties, from the City
University of New York. Landlord agrees to provide Tenant with a copy of the
executed termination agreement after Landlord's receipt of such agreement,
provided that Landlord's failure to deliver a copy of such agreement shall not
impair the validity of this Lease nor impose any liability therefore on
Landlord. If Landlord has not received a signed termination agreement, approved
by all necessary parties, from the City University of New York on or before
December 31, 1999, Tenant shall have the right to terminate this Lease on or
before February 15, 2000 by sending written notice to Landlord setting forth a
termination date, which shall be not less than 30 days nor more than 90 days
from the date of Tenant's notice.

            1.03 Possession Date. (a) "Possession Date" shall mean the day on
which Landlord's Initial Work (as defined below) is substantially completed in
accordance with Section 1.03(c). Landlord shall use reasonable efforts to
substantially complete Landlord's Initial Work on or before February 1, 2001. If
Landlord's Initial Work is substantially completed prior to February 1, 2001,
such date of substantial completion shall be the Possession Date. In the event
that the Possession Date does not occur on or before February 1, 2001, then the
Landlord shall provide Tenant with additional temporary office space, as
provided in Section 1.06(b) herein. Landlord shall advise Tenant of the date
Landlord's Initial Work is substantially completed and Landlord and Tenant shall
promptly confirm the Possession Date, the Rent Commencement Date and the
Expiration Date by a separate instrument to be prepared by Landlord; provided,
that the failure to execute and deliver such instrument shall not affect the
determination of such dates in accordance with this Lease. Tenant shall have the
right to dispute the determination of the Possession Date by submitting such
dispute to binding arbitration before the American Arbitration Association in
the City of New York, County of New York; provided that Tenant has not commenced
Tenant's Initial Improvements in the Premises or otherwise taken exclusive
possession of the Premises prior to Landlord's proposed Possession Date. Pending
the resolution of any dispute as to the Possession Date, Tenant shall pay Rent
based upon Landlord's determination.

                  (b) Landlord shall provide Tenant with written notice upon
Landlord obtaining vacant possession of the Original Premises from The City
University of New York, the tenant in possession of the space as of the date of
this Lease. Landlord also shall provide Tenant with 5 business days' written
notice of the anticipated date of completion of Landlord's Initial Work;
provided, that failure to deliver the Premises to Tenant on the anticipated date
of completion of Landlord's Initial Work shall not impair the validity of this
Lease nor shall it delay the Possession Date under this Lease.

                                      -2-

<PAGE>

                  (c) Landlord's Initial Work shall be deemed to have been
substantially completed on the date upon which Landlord's Initial Work has been
completed, except for (A) minor details or adjustments, (B) items which, in
accordance with good construction practice, should be performed after completion
of Tenant's Initial Improvements and (C) any part of Landlord's Initial Work
that is not completed due to Tenant Delay; provided, that in each case Landlord
shall nevertheless remain obligated to complete Landlord's Initial Work. If
Tenant takes exclusive possession of the Original Premises for the performance
of Tenant's Initial Work or for any other reason, Landlord's Initial Work shall
be deemed to be substantially complete. For purposes of this Section 1.03,
Tenant shall be deemed to have taken exclusive possession of the Original
Premises, notwithstanding the fact that Landlord may be performing the work
described in items (A), (B) and (C) of this Section 1.03(c) in the Original
Premises at such time as Tenant commences performance of Tenant's Initial Work.

                  (d) If for any reason Landlord shall be unable to deliver
possession of the Original Premises to Tenant on any date specified in this
Lease for such delivery, Landlord shall have no liability to Tenant therefor and
the validity of this Lease shall not be impaired, nor shall the Term be
extended, by reason thereof. This Section 1.03 shall be an express provision to
the contrary for purposes of Section 223-a of the New York Real Property Law and
any other law of like import now or hereafter in effect. Nothing contained
herein shall be deemed to diminish Tenant's rights under Section 1.06(e) of this
Lease.

                  (e) In no event shall the Possession Date occur prior to July
1, 2000.

            1.04 Tenant Delay. "Tenant Delay" means any delay which Landlord may
encounter in the performance of Landlord's obligations under this Lease solely
by reason of any act or omission of any nature of Tenant, its agents or
Contractors, including, without limitation, delays due to changes in or
additions to Landlord's Initial Work requested by Tenant, delays by Tenant in
submission of information or giving authorizations or approvals or delays due to
the postponement of any Landlord's Initial Work at the request of Tenant. Tenant
shall pay to Landlord any costs or expenses incurred by Landlord by reason of
any Tenant Delay.

            1.05 Use. The Premises shall be used and occupied by Tenant (and its
permitted subtenants) solely as general and executive offices (including such
ancillary uses in connection therewith as shall be reasonably required by Tenant
in the operation of its business which may include, but shall not be limited to,
a lunchroom and a kitchen, incidental to the use of the Premises as general and
executive offices and each exclusively for the use of Tenant's employees);
provided, that in no event shall the Premises be used for any of the following:
(a) a banking, trust company, or safe deposit business, (b) a savings bank, a
savings and loan association, or a loan company, (c) the sale of travelers'
checks and/or foreign exchange, (d) a stock brokerage office or for stock
brokerage purposes, (e) a restaurant, bar or for the sale of food or beverages,
(f) photographic reproductions and/or offset printing, (g) an employment or
travel agency or airline ticket counter, (h) a school or classroom, (i) medical
or psychiatric offices, (j) conduct of an auction, (k) gambling activities, (l)

organization, or (o) offices of any tax exempt entity within the meaning of
Section 168(h)(2) of the Internal Revenue Code of 1986, as amended, or any
successor or substitute statute, or rule or regulation applicable thereto. The
Premises shall not be used for any purpose which would tend to lower the
character of the Building, create unreasonable or excessive elevator or floor
loads, impair or interfere with any of the Building operations or the proper and
economic heating, ventilation, air-conditioning, cleaning or other servicing of
the Building, constitute a public or private nuisance, interfere with, annoy or
disturb any other tenant or Landlord, or impair the appearance of the Building.

            1.06 Temporary Space. (a) Landlord hereby leases to Tenant and
Tenant hereby hires from Landlord, subject to the terms and conditions of this
Lease, the entire 10th floor of Building B (the "First Temporary Space")

agree that the First Temporary Space is conclusively deemed to contain 12,217
rentable square feet. Tenant shall occupy the First Temporary Space beginning on
December 1, l999 ("First Temporary Space Occupancy Date"), and unless Tenant
shall have exercised its option to lease the First Temporary Space for the Term
of this Lease in accordance with Section 1.08 hereof, such occupancy of the
First Temporary Space shall end two (2) weeks after substantial completion of
Tenant's Initial Improvements, but, in no event, shall such occupancy extend
beyond one hundred eighty (180) days after the Possession Date (the "Temporary
Space Vacancy Date").

                  (b) In the event that the Possession Date shall not occur on
or before February 1, 2001, Landlord shall lease to Tenant and Tenant shall hire
from Landlord, subject to the terms and conditions of this Lease, additional
space suitable for the uses permitted under this Lease of at least 8,000 square
feet but no more than 12,000 square feet (the "Second Temporary Space" together
with the First Temporary Space, the "Temporary Space") in either (i) Building A
or (ii) Building B. Tenant shall occupy the Second Temporary Space beginning on
February 1, 2001, and such occupancy of the Second Temporary Space shall end,
unless sooner terminated as provided in this Lease, on the Temporary Space
Vacancy Date. Tenant shall have the right to reject the Second Temporary Space
offered by Landlord by notice to Landlord given within five (5) Business Days
after Landlord has designated such space, provided that, if Tenant so rejects
such Second Temporary Space, Landlord shall have no further obligation under
this Section 1.06(b) to provide additional temporary space to Tenant.

                  (c) The fixed rent for the First Temporary Space shall be at
an annual rate of $32.00 per rentable square foot of the First Temporary Space
for the period commencing on the First Temporary Space Occupancy Date and,
subject to Article 10 hereof, ending on the Temporary Space Vacancy Date. The
fixed rent for the Second Temporary Space shall be at an annual rate of $32.00

Section 2.03, other than any Tax Payments described in Section 2.04 and any
expense escalations described in Section 2.10, as are applicable to the
occupancy of both the First Temporary Space and the Second Temporary Space.

                  (e) Notwithstanding the foregoing, if Landlord does not
deliver the Original Premises to Tenant on or prior to September 30, 2001,
Tenant shall have the right to terminate this Lease by sending written notice (a
"Termination Notice") to Landlord at least thirty (30) days prior to Tenant's
desired termination date, which date shall be no later than 270 days after the
date of the Termination Notice (the "Termination Date"). If Tenant has not
delivered a Termination Notice and the Original Premises have not been delivered
to Tenant on or prior to December 31, 2001, either Tenant or Landlord shall have
the right to terminate this Lease by delivering a Termination Notice to the
other party; provided that Landlord shall only have the right to terminate this
Lease in accordance with this Section 1.06(e) if Landlord has made a reasonable
effort to deliver the Original Premises to Tenant as required under this Lease.
If Tenant delivers a Termination Notice pursuant to the preceding sentence, such
Termination Notice shall set forth a Termination Date, which date shall be not
less than 30 days nor more than 270 days from the date of the Termination

sentence, Tenant, within ten (10) Business Days thereafter, shall deliver to
Landlord a separate notice setting forth a Termination Date, which shall be not
less than 30 days nor more than 270 days from the date of the Termination Notice
delivered by Landlord. If Tenant has exercised the Expansion Option in
accordance with Article 10 of this Lease, then, subject to the provisions set
forth in this Section 1.06(e), (i) Landlord's right to terminate this Lease
provided hereunder shall be limited to terminating this Lease solely with
respect to the Original Premises and (ii) Tenant may elect to terminate this
Lease solely with respect to the Original Premises, provided that Tenant
notifies Landlord of such election in Tenant's Termination Notice. In the event
of such an election, this Lease shall remain in full force and effect with
respect to the Expansion Space.

            1.07 Additional 19th Floor Space. Landlord hereby notifies Tenant
that Landlord may elect to remove the unused, existing elevator shafts on the
19th Floor shown on Exhibit B-2 attached hereto and made a part hereof (the
"Additional 19th Floor Space") provided that if Landlord elects to remove such
elevator shafts, such removal shall be completed on or before the Possession
Date herein. Landlord shall notify Tenant on or before April 1, 2000 of
Landlord's intent to exercise its rights under this Section 1.07. In the event
that Landlord elects to remove such elevator shafts, the area previously
occupied by the Additional 19th Floor Space shall become part of the Original
Premises. Upon notice from Landlord to Tenant that Landlord will deliver the
Additional 19th Floor Space to Tenant on the Possession Date, and effective on

            2.03 Additional Charges. "Additional Charges" means Tax Payments and
all other sums of money, other than Fixed Rent, at any time payable by Tenant
under this Lease, all of which Additional Charges shall be deemed to be rent.

            2.04 Tax Payments. (a) "Base Tax Amount" means the Taxes (excluding
any amounts described in Section 2.04(b)(iii)) payable for the calendar year
2001 (the "Base Tax Year"). If the Base Tax Amount shall be reduced, for any
reason, such lesser amount shall be the Base Tax Amount used to compute Tenant's
Tax Share (as defined below) of any increase in Taxes for each Tax Year.

                  (b) "Taxes" means (i) the real estate taxes, sewer rents,
water frontage charges, vault taxes, assessments and special assessments levied,
assessed or imposed upon or with respect to Building A by any federal, state,
municipal or other government or governmental body or authority, (ii) all taxes
assessed or imposed with respect to the rentals payable under this Lease other
than general income and gross receipts taxes; provided, that any such tax shall
exclude Commercial Rent or Occupancy Taxes imposed pursuant to Title 11, Chapter
7 of the New York City Administrative Code so long as such tax is required to be
paid by tenants directly to the taxing authority and (iii) any expenses incurred
by Landlord in contesting such taxes or assessments and/or the assessed value of
the Project, which expenses shall be allocated to the Tax Year to which such
expenses relate (provided that, such expenses shall not be allocated until
Landlord receives the benefit, if any, of such a contest). If at any time the
method of taxation shall be altered so that in lieu of or as an addition to or
as a substitute for, the whole or any part of such real estate taxes,
assessments and special assessments now imposed on real estate, there shall be
levied, assessed or imposed (x) a tax, assessment, levy, imposition, fee or
charge wholly or partially as a capital levy or otherwise on the rents received
therefrom, or (y) any other additional or substitute tax, assessment, levy,
imposition, fee or charge, including, without limitation, business improvement
district and transportation taxes, fees and assessments, then all such taxes,
assessments, levies, impositions, fees or charges or the part thereof so
measured or based shall be included in "Taxes". If the owner, or lessee under a
Superior Lease, of all or any part of the Building and/or the Land is an entity
exempt from the payment of taxes described in clauses (i) and (ii), there shall
be included in "Taxes" the taxes described in clauses (i) and (ii)

                                      -7-

<PAGE>

which would be so levied, assessed or imposed if such owner or lessee were not
so exempt and such taxes shall be deemed to have been paid by Landlord on the
dates on which such taxes otherwise would have been payable if such owner or
lessee were not so exempt. Except as permitted in this Section 2.04(b), "Taxes"
shall not include any franchise, estate, income, capital stock or transfer tax.

                  (c) "Tax Year" means each period of 12 months, commencing on
the first day of July of each such period, in which occurs any part of the Term,
or such other period of 12 months occurring during the Term as hereafter may be
adopted as the fiscal year for real estate tax purposes of the City of New York.

                  (d) "Tenant's Tax Share" means 4.1879%. The parties hereto
agree that the rentable square foot area of the 19th Floor shall be deemed to be
19,713 rentable square feet and, solely for the purpose of calculating Tenant's
Tax Share, the rentable square foot area of Building A shall be deemed to be
470,717 rentable square feet. The Tenant's Tax Share has been determined by
dividing the rentable square foot area of the 19th Floor by the rentable square
foot area of Building A.

                  (e) If Taxes for any Tax Year, including the Tax Year in which
the Rent Commencement Date occurs, shall exceed the Base Tax Amount, Tenant
shall pay to Landlord (each, a "Tax Payment") Tenant's Tax Share of the amount
by which Taxes for such Tax Year are greater than the Base Tax Amount. Landlord
shall give Tenant a statement showing the computation of Tenant's Tax Share,
which statement shall cover only those Taxes which Landlord is then required to
pay to the taxing authority and such statement shall be accompanied by copies of
the applicable tax bills or other evidence showing the Taxes or tax assessments.
If there shall be any increase or decrease in the Taxes for any Tax Year, the
Tax Payment for such Tax Year shall be appropriately adjusted and paid or
refunded, as the case may be, in accordance herewith.

                  (f) If Landlord shall receive a refund of Taxes for any Tax
Year, Landlord shall pay to Tenant Tenant's Share of the net refund (after
deducting from such refund the costs and expenses of obtaining the same,
including, without limitation, appraisal, accounting and legal fees, to the
extent that such costs and expenses were not included in the Taxes for such Tax
Year); provided, that (i) Tenant shall not be eligible to receive such payment
if Tenant is in default of any payment of Fixed Rent beyond any applicable
notice and grace period under the Lease beyond any notice and grace period, if
applicable, and (ii) such payment to Tenant shall in no event exceed Tenant's
Tax Payment paid for such Tax Year.

                  (g) If the Taxes comprising the Base Tax Amount are reduced as
a result of an appropriate proceeding or otherwise, the Taxes as so reduced
shall for all purposes be deemed to be the Base Tax Amount and Landlord shall
notify Tenant of the amount by which the Tax Payments previously made were less
than the Tax Payments required to be made under this Section 2.04, and Tenant
shall pay the deficiency within 10 days after demand therefor.

                  (h) Landlord represents (i) that to its knowledge, without due
inquiry, there is no abatement(s) or exemption(s) of Taxes applicable to the
Building as of the date of the

                                      -8-

<PAGE>

Lease and (ii) Landlord has no actual knowledge of any pending abatement(s) or
exemption(s) for the Base Tax Year. A filing for certiorari for the Base Tax
Year shall not be deemed a violation of this provision. In the event there shall
be abatement(s) or exemption(s) in effect for the Base Tax Year, such
exemption(s)/abatement(s) shall not be taken into account in calculating the
Base Tax Amount.

            2.05 [INTENTIONALLY OMITTED]

            2.06 Tax Provisions. (a) In any case provided in Section 2.04 in
which Tenant is entitled to a refund, Landlord may, in lieu of making such
refund, credit against future installments of Rent any amounts to which Tenant
shall be entitled. Nothing in this Article 2 shall be construed so as to result
in a decrease in the Fixed Rent. If this Lease shall expire before any such
credit shall have been fully applied, then (provided Tenant is not in monetary
default beyond any applicable notice and grace period under this Lease) Landlord
shall refund to Tenant the unapplied balance of such credit.

                  (b) Landlord's failure to render or delay in rendering any
statement with respect to any Tax Payment or installment thereof shall not
prejudice Landlord's right to thereafter render such a statement, nor shall the
rendering of an incorrect statement for any Tax Payment or installment thereof
prejudice Landlord's right to thereafter render a corrected statement therefor.

                  (c) Landlord and Tenant confirm that the computations under
this Article 2 are intended to constitute a formula for agreed rental escalation
and may or may not constitute an actual reimbursement to Landlord for Taxes. If
the Building shall be condominiumized, then Tenant's Tax Payments shall, if
necessary, be equitably adjusted such that Tenant shall thereafter continue to
pay the same share of the Taxes of the Building as Tenant would pay in the
absence of such condominimization. If the size of either Building A or Building
B shall be increased due to a recalculation of the rentable square footage of
Building A or Building B or for any other reason, Tenant's Tax Share shall be
recalculated to reflect the ratio of the rentable square feet in the Premises to
the revised number of rentable square feet in Building A or Building B, as
appropriate.

                  (d) Each Tax Payment in respect of a Tax Year, which begins
prior to the Possession Date or ends after the expiration or earlier termination
of this Lease, and any tax refund pursuant to Section 2.04(f), shall be prorated
to correspond to that portion of such Tax Year occurring within the Term.

            2.07 Electric Charges. (a) Landlord shall supply the Original
Premises with electric service equal to at least six (6) watts demand load per
square foot of rentable space for lighting and receptacles, and six (6) watts
demand load per square foot of rentable space for air conditioning, and shall
cause Tenant's electric energy usage to be measured on a submetering basis. If
the electric service supplied to the Original Premises is supplied by more than
one (1) submeter, then the readings will be accumulated through a totalizing
meter and billed on a coincident demand basis as if billed through a single
meter. Landlord shall, at Landlord's expense, purchase and install the
submeter(s). Tenant shall pay Landlord, as additional rent, within ten (10) days
of receipt of its next rent bill, for the kw hours and kw demand used by Tenant
at the service classification under which the public utility bills Landlord
commensurate with the rate for

                                      -9-

<PAGE>

the usage as shown on Tenant's meters, plus five (5%) percent thereof for
providing, reading and billing the submetering service; provided, that at no
point will Tenant be entitled to time-of-day rates. Landlord shall have the sole
right to select the provider of electricity for the Building.

                  (b) If it shall become unlawful for Landlord to submeter
Tenant's electric energy usage, such usage shall thereafter be paid for and
measured as follows:

                        (i) Tenant agrees to pay for its electric usage as
additional rent (hereinafter referred to as the "Additional Rent for
Electricity"). The Additional Rent for Electricity shall be determined initially
by a survey of the Premises made by an electrical consultant or electrical
engineer chosen by Landlord. The survey so made will determine the number of kw
hours and kw demand based on the electrical equipment and fixtures in the
Premises and the period of use thereof, and based thereon will determine the
value, expressed in dollars per year, of Tenant's electric energy usage. The
rate Tenant shall pay will be the service classification under which the public
utility bills Landlord commensurate with the rate for usage as shown by the
survey, plus five (5%) percent of such amount for Landlord's administrative
costs; provided, that at no point will Tenant be entitled to time-of-day rates.
The Additional Rent for Electricity so determined, as adjusted from time to time
pursuant to subparagraphs (ii), (iii) and (iv), shall be paid by Tenant in equal
monthly installments in advance on the first day of each month during the Term,
without any set off or deduction of any kind.

                        (ii) If the public utility rate schedule for the supply
of electric current to the Building shall be increased or decreased subsequent
to the date of the survey referred to above, or if there shall be an increase or
decrease in the fuel adjustment or taxes, or if additional taxes, surcharges, or
charges of any kind shall be imposed upon the sale or furnishing of such
electric current, the Additional Rent for Electricity shall be increased or
decreased by applying the changed rate, fuel adjustment and taxes to the kw
hours and kw demand shown on the electric survey then in effect.

                        (iii) If there shall be a change subsequent to the
initial survey, or any future survey, in the Premises, or in the number of hours
during which the Premises is used, or if Tenant's failure to maintain its
installations in good order and repair causes greater consumption of electric
current, or if Tenant uses electricity for purposes other than the use permitted
hereunder, or if Tenant adds any fixtures, machinery or equipment which
significantly increases its electricity usage, the Additional Rent for
Electricity, theretofore adjusted, shall be increased by applying to the
additional kw hours and kw demand furnished by Landlord the Service
Classification Rate under which the public utility bills Landlord commensurate
with the rate for the usage as shown by the survey, plus five (5%) percent of
such amount for Landlord's administrative costs (provided, that at no point will
Tenant be entitled to time-of-day rates). If Tenant's electricity usage shall
decrease due to the use of its electric fixtures or equipment for lesser periods
of time, or due to less or more efficient fixtures or equipment, the Additional
Rent for Electricity, theretofore adjusted, shall be decreased by applying the
Service Classification Rate aforesaid to the lesser kw hours and kw demand.

                        (iv) Landlord and Tenant shall each have the right from
time to time during the Term to have an electric rate consultant or electrical
engineer survey the electric

                                      -10-

<PAGE>

current consumed by Tenant in the Premises. If such consultant determines that
the value of the electric current furnished Tenant is more or less than the
Additional Rent for Electricity, as most recently adjusted, such annual amount
shall be further adjusted to equal the amount determined by said consultant. The
cost of the survey shall be borne by the party ordering the same.

                        (v) Landlord shall deliver a copy of the initial survey,
and a copy of any future survey made pursuant to this Section 2.07(b), to
Tenant, and Tenant shall have sixty (60) days within which it may protest the
findings contained therein. If Tenant fails to protest within the sixty (60) day
period, the findings contained in the survey shall be final. If Tenant protests
within the sixty (60) day period (by sending Landlord a notice in the manner
herein provided for the giving of notices), Tenant shall have a second survey
made by an electric engineer or electric rate consultant of its choice, and
deliver a copy thereof to Landlord within sixty (60) days of the date of the
protest. If Landlord's and Tenant's surveyors are unable to agree upon the
amount of electric energy consumed by Tenant, or the amount of any increase or
decrease, or an any other matter contained in the surveys, the determination of
the same shall be submitted to arbitration under the rules of the American
Arbitration Association then obtaining. The determination of the electric rate
consultant or engineer, or the American Arbitration Association if there is
disagreement and the determination is submitted to arbitration made pursuant to
this subparagraph, shall be binding on Landlord and Tenant. The parties hereto
shall, within ten (10) days from the date of any such determination, execute,
acknowledge and deliver to each other an agreement setting forth the adjusted
Additional Rent for Electricity, but such increase or decrease shall be
effective from the date of the increase or decrease (subparagraph (ii)), or
change (subparagraph (iii)), or new survey (subparagraph (iv)), whether or not
such agreement is executed, and notwithstanding the date of execution thereof.

                  (c) Landlord shall not in any way be liable or responsible to
Tenant, except where due to its negligence, for any loss, damage or expense
which Tenant may sustain or incur if during the Term, by reason of the act or
inaction of the public utility servicing the Building, either the quantity or
character of electrical energy is changed or is no longer available or suitable
for Tenant's requirements. Landlord shall not be obligated to increase the
existing electrical capacity of any portion of the Building's systems, nor to
provide any additional wiring or capacity to meet Tenant's requirements, other
than as set forth in Section 2.07(a). Tenant shall make no substantial
alteration or addition to the electrical equipment in the Premises as of the
commencement of the Term, nor increase the use of electricity in the Premises
without the prior written consent of the Landlord in each instance, which
consent Landlord agrees not to unreasonably withhold or delay. Subject to
Landlord's obligation set forth in Section 2.07(a) herein, Tenant covenants and
agrees that at all times its use of electric current shall never exceed the
capacity of the then existing feeders of the Building or the risers or wiring
installations, and further agrees that Tenant may not use any electrical
equipment which, in Landlord's opinion, reasonably exercised, will overload such
installations or interfere with the use thereof by any other tenants of the
Building.

            2.08 Manner of Payment. Tenant shall pay all Rent and all other sums
as the same shall become due and payable under this Lease either by wire
transfer of immediately available federal funds as directed by Landlord or by
check (subject to collection) drawn on a New York Clearing House Association
member bank, in each case at the times provided herein

                                      -11-

<PAGE>

without notice or demand and without setoff or counterclaim. All Rent shall be
paid in lawful. money of the United States to Landlord at its office or such
other place as Landlord may from time to time designate. If Tenant fails timely
to pay any Rent, Tenant shall pay interest thereon from the date when such Rent
became due to the date of Landlord's receipt thereof at the lesser of (i) 1 1/2%
per month or (ii) the maximum rate permitted by law. Any Additional Charges for
which no due date is specified in this Lease shall be due and payable on the
10th day after the date of Landlord's invoice therefor. All bills, invoices and
statements rendered to Tenant with respect to this Lease shall be binding and
conclusive on Tenant unless, within 60 days after receipt of same, Tenant
notifies Landlord that it is disputing same. Notwithstanding anything to the
contrary contained in this Lease, Rent shall be due and payable on the first day
of the month, and failure to pay such Rent on or prior to the first day of any
month shall be considered a default under this Lease and interest shall accrue
as provided in this Section 2.08 from and after the first day the Rent becomes
due and payable.

            2.09 Security. (a) Upon the execution of this Lease, Tenant has
delivered to Landlord, as security for the performance of Tenant's obligations
under this Lease, either (i) the sum of $400,000.00, in certified or official
bank check (the "Initial Security Deposit"), or (ii) an unconditional,
irrevocable letter of credit in the amount of $400,000.00 in a form and issued
by a bank reasonably satisfactory to Landlord (the "Initial Letter of Credit").
Within ten (10) days after notice from Landlord to Tenant that the Premises are
vacant and Landlord is in possession of the Premises, Tenant shall deliver to
Landlord, as further security for the performance of Tenant's obligations under
this Lease, either (i) the sum of $1,400,000.00, in certified or official bank
check (the "Additional Security Deposit" together with the Initial Security
Deposit, the "Security Deposit") or (ii) an unconditional, irrevocable letter of
credit in the amount of $1,400,000.00 in a form issued by a bank reasonably
satisfactory to Landlord (the "Additional Letter of Credit" together with the
Initial Letter of Credit, the "Letter of Credit"). The Letter of Credit shall
provide that it is assignable by Landlord without charge and shall either (A)
expire on the date which is 60 days after the expiration or earlier termination
of this Lease (the "LC Date") or (B) be automatically self-renewing until the LC
Date. If any Letter of Credit is not renewed at least 30 days prior to the
expiration thereof or if Tenant holds over in the Premises without the consent
of Landlord after the expiration or termination of this Lease, Landlord may draw
upon the Letter of Credit and hold the proceeds thereof as security for the
performance of Tenant's obligations under this Lease including, but not limited
to, damages under Section 6.05 hereof. Landlord may draw on the Security Deposit
or Letter of Credit (or the proceeds thereof) solely to remedy defaults by
Tenant, which are beyond any applicable notice and grace period, in the payment
or performance of any of Tenant's obligations under this Lease. If Landlord
shall have so drawn upon the Security Deposit or the Letter of Credit (or the
proceeds thereof), Tenant shall upon demand deposit with Landlord a sum equal to
the amount so drawn by Landlord. Landlord hereby agrees that a Letter of Credit
issued (i) in the form set forth in Exhibit I attached hereto and made a part
hereof and (ii) by Amalgamated Bank shall be deemed to be reasonably
satisfactory to Landlord. If Tenant delivers the Security Deposit to Landlord in
cash, then the Security Deposit shall be kept in an interest-bearing account
until applied in accordance with the terms of this Lease (it being understood
that Landlord shall not be liable for failure to obtain any specific level of
interest). Landlord shall pay such interest to Tenant, less a one (1%) percent
administrative fee, no more frequently than annually, upon the request of
Tenant.

                                      -12-

<PAGE>

                  (b) In the event that Tenant shall have prior to the
expiration of the Election Period elected to forego receipt of Landlord's
Contribution pursuant to Section 2.02(b) above, the amount of the Security
Deposit required hereunder shall be reduced by seven hundred thirty thousand
three hundred ninety-five ($730,395.00) dollars plus any amount added to
Landlord's Contribution resulting from the inclusion of the Additional 19th
Floor Space in accordance with Section 1.07 of this Lease.

                  (c) If, at any time, Tenant (i) completes a secondary public
offering of fifty million dollars ($50,000,000.00) or more (the "Minimum Equity
Amount") or (ii) otherwise receives an equity infusion of the Minimum Equity
Amount, which Minimum Equity Amount, by the terms of the documents governing the
same, can be used by Tenant as working capital, then the Security Deposit
required hereunder shall be reduced to one million dollars ($1,000,000.00).

                  (d) If, prior to the expiration of the Election Period, Tenant
has elected to forego receipt of Landlord's Contribution pursuant to Section
2.02(b) above, and if Tenant meets the requirements of Section 2.09(c) above,
then the Security Deposit hereunder shall be reduced to five hundred thousand
($500,000) dollars (the "Minimum Security Amount").

                  (e) If, from and after the Possession Date, (A) there is not a
monetary default beyond any applicable notice and grace period under this Lease
and (B) Tenant delivers to Landlord evidence that it has a NOI (as defined
below) of at least four million ($4,000,000.00) dollars and that the Tenant has
maintained a NAV (as defined below) of at least twenty million ($20,000,000.00)
dollars during the preceding twenty-four (24) month period, then the Security
Deposit shall be reduced to five hundred thousand ($500,000.00) dollars.

                  (f) If the Security Deposit has not otherwise been reduced to
the Minimum Security Amount, then:

                        (i) if, during the first five (5) years of the Term,
there have not occurred more than three (3) monetary defaults beyond any
applicable notice and grace period under this Lease, then upon the sixth (6th)
anniversary of the Rent Commencement Date, the Security Deposit shall be reduced
by four hundred thousand ($400,000) dollars; and

                        (ii) if, during the first ten (10) years of the Term,
there have not occurred more than six (6) monetary defaults beyond any
applicable notice and grace period, then upon the eleventh (11th) anniversary of
the Rent Commencement Date, the Security Deposit shall be reduced by four
hundred thousand, ($400,000) dollars; and

                  (g) If the Security Deposit is reduced pursuant to Section
2.09(f)(i) or (ii) above, and after the date of such reduction there occurs more
than three (3) monetary defaults, beyond any applicable notice and grace period,
within any five (5) year period, the Security Deposit required shall be
increased to the amount of such Security Deposit immediately prior to such
reduction and Tenant shall be required to deliver to Landlord as further
security for the performance of Tenant's obligations under this Lease, within
ten (10) days notice from Landlord and in accordance with the provisions of
Section 2.09(a) above, four hundred thousand ($400,000) dollars.

                                      -13-

<PAGE>

                  (h) As used herein the term "NOI" shall mean net income,
adjusted for non-cash charges, including, without limitation, depreciation,
amortization, and deferred income taxes. The term "NAV" shall mean total assets,
less total liabilities. Total assets shall not include (i) deferred charges,
(ii) intangibles (including, without limitation, patents, software development
costs or goodwill), or (iii) receivables from stockholders, officers, or
affiliates.

                  (i) Notwithstanding anything to the contrary contained in this
Section 2.09, in no event shall the Security Deposit be reduced to less than the
Minimum Security Amount.

                  (j) In the event that Tenant is entitled to a reduction in the
amount of the Security Deposit under Sections 2.09(c), (d), (e) or (f) above,
Landlord shall (1) if the Security Deposit was paid in cash, return the amount
of such reduction to Tenant by check or (2) if the Security Deposit was given in
the form of a Letter of Credit, exchange the existing Letter of Credit for a
Letter of Credit in the amount of the reduced Security Deposit. If, within
thirty (30) days after receiving notice from Tenant that Tenant is entitled to a
reduction in the Security Deposit, unless Landlord is disputing the same,
Landlord does not return the amount of the reduction to Tenant or, if
applicable, cooperate with Tenant in obtaining a new Letter of Credit for the
reduced amount of the Security Deposit, then Tenant shall be entitled to
interest, at the Interest Rate, on the amount of the reduction of the Security
Deposit. "Interest Rate" means the lesser of (i) the prime rate from time to
time announced by Citibank, N.A. (or, if Citibank, NA. shall not exist, such
other bank in New York, New York, as shall be designated by Landlord in a notice
to Tenant) to be in effect at its principal office in New York, New York plus 2%
or (ii) the maximum rate permitted by law.

            2.10 Expense Escalation. (A) As used in this Lease:

                        (i) "Wage Rate" means the full minimum regular hourly
rate of wages including, without limitation, adjustments of every kind, but
specifically excluding fringe benefits, in effect as of January 1st of each year
(whether paid by Landlord or any contractor employed by Landlord) computed as
paid over a forty (40) hour week to Porters in Class A office buildings pursuant
to an Agreement between The Realty Advisory Board on Labor Relations,
Incorporated, or any successor thereto ("Realty Advisory Board"), and Local
32B-32J of the Building Service Employees International Union ("Local 32B-32J"),
AFL-CIO, or any successor thereto; and provided, however, that if there is no
such agreement in effect prescribing a wage rate for Porters, computations and
payments shall thereupon be made upon the basis of the regular hourly wage rate
actually payable to Porters by Landlord or by Landlord's service contractors
over a forty (40) hour week, in effect as of January 1st of each year, and
provided, however, that if in any year during the Term the regular employment of
Porters shall occur on days or during hours which overtime or other premium pay
rates are in effect pursuant to such Agreement, then the term "hourly rate of
wages" as used herein shall be deemed to mean the average hourly rate for the
hours in a calendar week during which Porters are regularly employed (e.g., if
pursuant to an agreement between Realty Advisory Board and the Local 32B-32J the
regular employment of Porters for forty hours during a calendar week is at a
regular hourly wage rate of $3.00 for the first thirty hours, and premium or
overtime hourly wage rate of $4.50 for the remaining ten hours, then the hourly
rate of wages under this Article during such period shall be

                                      -14-

<PAGE>

total weekly rate of $135.0O divided by the total number of regular hours of
employment, forty or $3.375).

                        (ii) "Base Wage Rate" means the Wage Rate in effect for
calendar year 2001.

                        (iii) The term "Porters" means that classification of
non-supervisory employees employed in and about the Building who devote a major
portion of their time to general cleaning, maintenance and miscellaneous
services essentially of a non-technical and non-mechanical nature and are the
type of employees who are presently included in the classification of "Class
A-Others" in the Commercial Building Agreement between the Realty Advisory Board
and Local 32B-32J.

                        (iv) "Multiplication Factor" shall mean the product
obtained by multiplying the area of the Original Premises (which, for the
purposes of this Article, the parties have agreed shall be 21,735 rentable
square feet, as the same may be increased or decreased pursuant to the express
provisions of this Lease) by one (1).

                  (B) If the Wage Rate for any calendar year during the Term
shall be greater than the Base Wage Rate, then Tenant shall pay, as additional
rent, an amount (the "Wage Increase Charge") equal to the product obtained by
multiplying the Multiplication Factor by the number of cents (including any
fraction of a cent) by which the Wage Rage is greater than the Base Wage Rate,
such payment to be made in equal monthly installments commencing with the first
monthly installments of fixed rent falling due on or after the effective date of
such increase in Wage Rate (payable retroactive from said effective date) and
continuing thereafter until a new adjustment shall have become effective in
accordance with the provisions of this Section. Landlord shall give Tenant
notice of each change in Wage Rate that will be effective to create or change
Tenant's obligation to pay the Wage Increase Charge pursuant to the provisions
of this Article, which notice shall contain Landlord's calculation of the Wage
Increase Charge payable resulting from such increase in Wage Rate. The Wage
Increase Charge shall be prorated, if necessary, to correspond with that portion
of a calendar year occurring within the Term. Such notice shall be served in
accordance with the terms of this Lease and shall be accompanied by such
information which shall be reasonably necessary for Tenant to evaluate the
accuracy thereof.

                  (C) Every notice given by Landlord pursuant to Paragraph B of
this Section shall be conclusive and binding upon Tenant unless (i) within
ninety (90) days after the receipt of such notice, Tenant shall notify (a
"Dispute Notice") Landlord that it disputes the correctness of the notice,
specifying the particular respects in which the notice is claimed to be
incorrect and (ii) if such dispute shall not have been settled by agreement,
Tenant shall submit the dispute to binding arbitration before the American
Arbitration Association in the City of New York, County of New York, within
sixty (60) days after the date of the Dispute Notice. If such dispute is
submitted to arbitration, the non-prevailing party shall, upon demand, reimburse
the prevailing party for any attorney's fees, disbursements and other costs
related to the arbitration. Pending the determination of such dispute, Tenant
shall pay the Wage Increase Charge in accordance with Landlord's notice without
prejudice to Tenant's position of such dispute. In the event such dispute shall
be determined in Tenant's favor, Landlord shall, on demand, pay Tenant

                                      -15-

<PAGE>

the amount so overpaid by Tenant plus interest at the Interest Rate, which such
interest shall be calculated from the date on which Tenant first paid the
disputed Wage Increase Charge.

                  (D) The Wage Rate is intended to be a substitute comparative
index of economic costs and inflationary pressures and does not necessarily
reflect the actual costs of wages or other expenses of operating the Building.
The Wage Rate shall be used whether or not the building is a Class A office
building, whether or not porters are employed in the Building and without regard
to whether such employees are members of the union referred to in Paragraph A of
this Section.

            3.01 Landlord Services. (a) Except as specifically provided
otherwise herein, from and after the date that Tenant first occupies the

with the following services (collectively, "Landlord Services"):

                        (i) (A) passenger elevator service to the 19th Floor,
with at least three (3) passenger elevators available at all times during
Business Hours on Business Days and at least one passenger elevator subject to
call at all other times, it being agreed that two of such passenger elevators
shall service floors 14 through 19 only and (B) freight elevator service to the
Premises and use of the loading dock on a first come-first served basis (i.e.,
no advance scheduling) from 8:00 am. to 5:00 p.m. on Business Days, and on a
reserved basis at all other times upon the payment of Landlord's actual cost for
the use of the freight elevator and loading dock including, without limitation,
the cost of an operator for the elevator; the use of all elevators shall be on a
nonexclusive basis;

                        (ii) reasonable quantities of hot and cold water to the

purposes only; if Tenant requires water for any other purpose, Landlord shall
furnish cold water at the Building core riser through a capped outlet to be
installed at Tenant's expense located on the floor on which the Premises is
located (within the core of the Building), and the cost of heating such water,
as well as the cost of piping and supplying such water to the Premises, shall be
paid by Tenant; Landlord may install and maintain, at Tenant's expense, meters
to measure Tenant's consumption of cold water and/or hot water for such other
purposes in which event Tenant shall reimburse Landlord for the quantities of
cold water and hot water shown on such meters (including Landlord's standard
charge for the production of such hot water, if produced by Landlord), on
demand;

                        (iii) electrical capacity equal to at least six (6)

<PAGE>

that Tenant shall be responsible for bringing such electrical capacity from the
electrical closet to the Premises); subject to Landlord's obligation to provide
the electrical capacity set forth herein, in no event shall Tenant's consumption
of electricity exceed the capacity of existing feeders to the Building or the
risers or wiring serving the Premises, nor shall Tenant be entitled to any
unallocated power available in the Building unless, in Landlord's judgment
(taking into account the then existing and future needs of other then existing
and future tenants, and other needs of the Building), the same is available and
necessary for Tenant's use; and

                        (iv) cleaning services in accordance with Exhibit E
attached hereto. Landlord shall not be required to perform any (A) extra

portions of the Premises used for preparation, serving or consumption of food or
beverages, training rooms, data processing or reproducing operations, private
lavatories or toilets or other special purposes requiring greater or more
difficult cleaning work than office areas, and Tenant shall retain Landlord's
cleaning staff or Landlord's cleaning contractor, as applicable, to perform such
cleaning at Tenant's expense. Landlord's cleaning staff or Landlord's cleaning
contractor, as applicable, shall have access to the Premises after 6:00 p.m. and
before 8:00 a.m. and shall have the right to use, without charge therefor, all
light, power and water in the Premises reasonably required to clean the
Premises.

                  (b) From and after the date that Tenant first occupies the
First Temporary Space, and if Tenant takes occupancy of the Second Temporary
Space as provided under Section 1.06(b), from and after the date that Tenant
first occupies the Second Temporary Space, Landlord shall furnish Tenant with:

                        (i) the Landlord Services described in Section 3.01(a)
above, and

                        (ii) heat, ventilation and air-conditioning to the
Temporary Space during Business Hours on Business Days; if Tenant shall require
heat, ventilation or air conditioning services at any other times, Landlord
shall furnish such service at a rate that reasonably reflects the actual cost to
Landlord of providing the service in question, which shall in no event be less
than $150.00 per hour, for a minimum of four (4) hours; provided that if other
tenants in Building B also have requested that Landlord provide such overtime
service, the cost of such overtime service shall be divided pro rata among all
tenants requesting such overtime service. Air-conditioning shall only be
available from May 1st through October 15th.

                        (iii) Landlord shall deliver to each floor of the
Temporary Space 30 tons of air conditioning per floor with adequate condenser
water (up to 30 tons) from Landlord's cooling towers to service such air
conditioning from May 15th through October 15th on Business Days during Business
Hours. Tenant shall have the right to install supplementary or

                                      -17-

<PAGE>

auxiliary air-cooled HVAC equipment to serve the Temporary Space, the
specifications and installation of which system shall be subject to Landlord's
approval. From May 1st through October 15th, if Tenant requires condenser water
from Landlord's cooling towers for more extended hours or on Non-Business Days
or on holidays, Landlord will furnish the same, at Tenant's expense, in an
amount equal to $150.00 per hour, for a minimum of four (4) hours; provided that
if other tenants in Building B also have requested that Landlord provide such
overtime service, the cost of such overtime service shall be divided pro rata
among all tenants requesting such overtime service.

                  (c) Tenant acknowledges that (i) the 19th Floor Mezzanine
shall be used as permitted under Section 1.01(b) herein and (ii) with the
exception of electricity and cleaning as described in Sections 3.01(a)(iii) and
(iv), the Landlord Services described in Section 3.01(a) above shall not be
provided to the 19th Floor Mezzanine.

                  (d) Landlord may stop or interrupt any Landlord Services,
electricity, or other service and may stop or interrupt the use of any Building
facilities and systems at such times as may be necessary and for as long as may
reasonably be required by reason of accidents, strikes, or the making of
repairs, alterations or improvements, or inability to secure a proper supply of
fuel, gas, steam, water, electricity, labor or supplies, or by reason of any
other cause beyond the reasonable control of Landlord. Landlord shall have no
liability to Tenant by reason of any stoppage or interruption of any Landlord
Service, electricity or other service or the use of any Building facilities and
systems for any reason. Landlord shall use reasonable diligence (which shall not
include incurring overtime charges) to make such repairs as may be required to
machinery or equipment within the Project to provide restoration of any Landlord
Services and, where the cessation or interruption of such Landlord Services has
occurred due to circumstances or conditions beyond the Project boundaries, to
cause the same to be restored by diligent application or request to the
provider.

                  (e) Without limiting any of Landlord's other rights and
remedies, if Tenant shall be in monetary default beyond any applicable notice
and grace period, Landlord shall not be obligated to furnish to the Premises any
overtime service outside of Business Hours on Business Days, and Landlord shall
have no liability to Tenant by reason of any failure to provide, or
discontinuance of, any such service.

                  (f) "Business Hours" means 8:00 a.m. to 6:00 p.m. "Business
Days" means all days except Saturday, Sundays, holidays as outlined in the Rules
and Regulations (as defined below) and any other days which are either (i)

service contract or operating engineers contract.

                  (g) "Rules and Regulations" means the rules and regulations
attached hereto as Exhibit C, as the same may be modified or amended from time
to time. If there is any conflict between the provisions of the Rules and
Regulations and the provisions of this Lease, the provisions of this Lease will
control. Landlord shall not discriminate against Tenant in the promulgation and
enforcement of the Rules and Regulations of the Building.

                  (h) Tenant acknowledges that (i) both the 19th Floor and the
19th Floor Mezzanine are serviced by independent heating/cooling units,
(specifically seven (7) ten-ton Carrier heating/cooling units and one (1)
five-ton Carrier heating/cooling unit) for the purposes of providing heat,
air-conditioning and ventilation to the 19th Floor and the 19th Floor Mezzanine
and (ii) Landlord shall not be obligated to otherwise provide heat,
air-conditioning and ventilation to the 19th Floor or the 19th Floor Mezzanine.

                  (i) Landlord agrees to continue to operate the Building to the
same standard that the Building is operated as of the date of this Lease.

                    Leasehold Improvements; Tenant Covenants

            4.01 Initial Improvements. (a) Landlord, at Landlord's expense,
shall perform or cause to be performed the initial work described on Exhibit F
("Landlord's Initial Work") in accordance with the provisions thereof. On the
Possession Date, Tenant shall accept the Original Premises in its "as is"
condition on such date; provided that Landlord's Initial Work shall be
substantially complete as required under Section 1.03 above. All other
improvements which do not constitute Landlord's Initial Work shall be performed
by Tenant at Tenant's expense in accordance with Section 4.02.

            (b) Tenant agrees to improve the Original Premises and, if Tenant
exercises Tenant's Expansion Option, the Expansion Space, in accordance with
detailed specifications and working drawings to be prepared by Tenant's
architect. The detailed specifications and working drawings are hereinafter
referred to as "Tenant's Plans", and the work shown by the Tenant's Plans is
hereinafter referred to as "Tenant's Initial Improvements".

            (c) Tenant shall proceed forthwith to cause Tenant's Plans to be
prepared by an architect licensed as such in the State of New York. Tenant's
Plans, including structural and mechanical drawings and specifications, shall be
prepared at Tenant's sole cost and expense. Tenant shall submit at least three
(3) full sets of Tenant's Plans to Landlord for Landlord's approval. Landlord
agrees to review Tenant's Plans and to approve the same or make written
exceptions thereto within thirty (30) days from the date of the submission of
the plans. Landlord agrees not to unreasonably withhold or delay its approval of
Tenant's Plans, and failure by Landlord to provide the written exceptions within
the thirty (30) day period aforesaid shall be deemed approval of Tenant's Plans.
If Landlord disapproves Tenant's Plans, Landlord shall provide Tenant with the
written exceptions to Tenant's Plans and Tenant shall revise them and re-submit
them to Landlord for approval. Landlord shall review the resubmitted Tenant's
Plans and shall approve the same or make written exceptions thereto within
fifteen (15) days from the date of the resubmission of the Plans. Upon approval
by Landlord of Tenant's Plans, Tenant shall submit the same to the New York City
Department of Buildings for approval, to the extent required by law, and for
issuance of a building permit to perform the Improvements, if required by

                                      -19-

<PAGE>

law. Tenant acknowledges that preparation of a Fire Protection Plan with respect
to the Premises may be a prerequisite to obtaining a sign-off on Tenant's
Initial Improvements, and Tenant agrees to prepare the same at its expense if
one is required. Landlord agrees, at Tenant's cost and expense, to cooperate
with Tenant and Tenant's architect and engineer in providing information needed
for the preparation of Tenant's Plans, the Fire Protection Plan, the application
for a building permit and all other permits required for the Improvements, and
to promptly execute all documents required to be signed by Landlord.

            (d) Tenant agrees to hire a reputable general contractor,
construction manager or subcontractors and materialmen (hereinafter
"Contractor(s)") from a list of contractors to be approved by Landlord (which
approval shall not be unreasonably withheld or delayed) to perform Tenant's
Initial Improvements in a good and workmanlike manner in accordance with (x) the
approved Tenant's Plans and any material amendments or additions thereto
approved by Tenant and Landlord and all municipal authorities having
jurisdiction, and (y) all provisions of Laws and any and all permits and other
requirements specified by any ordinance, law or public regulation. Tenant shall
cause the Contractor(s) to obtain and maintain throughout the work, Workers'
Compensation Insurance, New York State Disability Insurance and comprehensive
general liability insurance, including contractual liability coverage, in an
amount of not less thin $2 million combined single limit for bodily injury or
death for any one occurrence, and for property damage, plus a $5 million
umbrella policy. The liability coverage shall name Landlord and Orda Management
Corporation as additional insured parties, and Tenant shall deliver to Landlord
proper certificates of insurance confirming the coverages described above prior
to commencement of Tenant's Initial Improvements. If Tenant acts as its own
General Contractor or Construction Manager, Tenant shall obtain and maintain
such insurance. All Contractor(s) shall be members of a union affiliated with
the building trades in the City of New York that has jurisdiction over the
Building and Tenant's Initial Improvements.

            (e) Unless Tenant shall have elected to forego the same pursuant to
Section 2.02(b) above, Landlord agrees to contribute Thirty-Five ($35) Dollars
per rentable square foot of the 19th Floor and Twenty ($20) Dollars per rentable
square foot of the 19th Floor Mezzanine, for a total of $730,395.00 (subject to
any amount added to Landlord's Contribution resulting from the inclusion of the
Additional 19th Floor Space in accordance with Section 1.07 of this Lease),
toward the cost of the Tenant's Initial Improvements ("Landlord's
Contribution"). Landlord shall pay the Landlord's Contribution to Tenant's
Contractor(s) over the duration of the construction, no more frequently than
monthly, on receipt of a notice from Tenant of the names of the Contractor(s)
who performed work or supplied materials with respect to Tenant's Initial
Improvements, together with an Application and Certificate for Payment on AIA
Document G702 and G703, or similar form, duly executed by the Contractor(s) to
be paid, and Tenant's architect, who shall certify to Landlord (i) that the work
performed and materials delivered under said application generally conform to
Tenant's Plans, (ii) that the amount of such payment request approved by the
architect is justified by the work, (iii) the percentage of Tenant's Initial
Improvements completed by that date, (iv) that no less than 85% of the cost of
work to be paid from Landlord's Contribution (i.e., $620,835.75) has been
incurred in respect of hard costs and (v) that in said architect's opinion
adequate funds remain to complete Tenant's Initial Improvements. Landlord may
retain ten (10%) percent of each requested amount until ten (10) days after (w)
substantial completion of Tenant's Initial Improvements, (x) delivery to
Landlord

                                      -20-

<PAGE>

of waivers of mechanic's/materialmen's liens from all of Tenant's Contractor(s)
for amounts paid to date, and statements from the Contractor(s) stating the
balance owed, (y) receipt of invoices, requisitions, canceled checks or other
documentary evidence showing payment of the cost of Tenant's Initial
Improvements, and (z) receipt of two (2) sets of as-built drawings, or drawings
marked "Final", of the improved Premises. For each request for payment made by
Tenant, the amount of Landlord's Contribution to be paid to Tenant's
Contractor(s) shall be determined by multiplying the amount due to Tenant's
Contractors by the Pro Rata Share. "Pro Rata Share" shall mean the ratio of
Landlord's Contribution to the total estimated cost of Tenant's Initial
Improvements.

            (f) If Landlord fails to pay any portion of Landlord's Contribution
as provided in Section 4.01(e) above within thirty (30) days from receipt of a
notice from Tenant, Landlord shall pay to Tenant interest, at the Interest Rate,
on the unpaid amount.

            (g) All fees payable to municipal authorities by reason of Tenant's
Initial Improvements, and by reason of any hook-up into the Building's existing
fire alarm and communication systems, shall be part of, and not in addition to,
the Landlord's Contribution.

            (h) Tenant shall pay Orda Management Corporation, within ten (10)
days after being billed therefor, the reasonable actual out of pocket fees and
disbursements paid by Landlord to architects and engineers for reviewing
Tenant's Plans; provided, that, in no event shall the cost to Tenant exceed two
thousand five hundred ($2,500.00) dollars.

            (i) From the date of this Lease to the Possession Date, Landlord
shall, upon reasonable notice from Tenant, arrange for Tenant and Tenant's
architects to have reasonable access to the Premises during Business Hours and
on Business Days for the purpose of permitting Tenant's architects and other
consultants an opportunity to prepare plans for Tenant's Initial Work.

            (j) Tenant shall deliver to Landlord, within 30 days after the
completion of Tenant's Initial Improvements, five sets of "as-built" drawings
thereof prepared and certified by Tenant's architect. During the Term, Tenant
shall keep records of Tenant's Initial Improvements including plans and
specifications, copies of contracts, invoices, evidence of payment and all other
records customarily maintained in the real estate business relating to Tenant's
Initial Improvements and the cost of such improvements. Tenant shall, within 30
days after demand by Landlord, furnish to Landlord copies of such records.

            4.02 Alterations. (a) Tenant shall make no improvements, changes or
alterations in or to the Premises ("Alterations") without Landlord's prior
written approval. Provided Tenant is not in default under this Lease beyond any
applicable notice and/or cure period, Landlord shall not unreasonably withhold,
delay or condition its approval to any Alteration that is not a Material
Alteration. "Material Alteration" means an Alteration that (i) is not limited to
the interior of the Premises or which affects the exterior (including the
appearance) of the Building, (ii) is structural or affects the strength of the
Building, (iii) affects the usage or the proper functioning of any of the
Building systems, (iv) has a cost greater than $250,000

                                      -21-

<PAGE>

(v) requires the consent of any Superior Mortgagee or Superior Lessor and/or
(vi) requires a building permit.

                  (b) Tenant, in connection with any Alteration, shall comply
with the Rules and Regulations applicable thereto. Tenant shall not proceed with
any Alteration unless and until Landlord approves Tenant's plans and
specifications ("Alteration Plans") therefor in writing. Tenant shall submit at
least three (3) full sets of Tenant's plans and specifications to Landlord for
Landlord's approval. Landlord shall have thirty (30) days from the submission of
Tenant's Alteration Plans to approve or disapprove of such plans. If Landlord
fails to approve or disapprove Tenant's Alteration Plans during such period, the
same shall be deemed approved. Landlord shall notify Tenant of which fixtures,
equipment and improvements must be removed at the expiration of the Term when
notifying Tenant of its approval or disapproval of Tenant's Alteration Plans; if
Landlord does not so notify Tenant, then Landlord shall not require Tenant to
remove such fixtures, equipment and improvements at the expiration of the Term.
Any review or approval by Landlord of Tenant's Alteration Plans is solely for
Landlord's benefit, and without any representation or warranty to Tenant with
respect to the adequacy, correctness or efficiency thereof, its compliance with
Laws or otherwise.

                  (c) Tenant shall pay to Landlord upon demand Landlord's
reasonable out-of-pocket costs and expenses (including, without limitation, the
fees of any architect or engineer employed by Landlord or any Superior Lessor or
Superior Mortgagee for such purpose) for reviewing Tenant's Alteration Plans and
inspecting Alterations; provided, that in no event shall the cost to Tenant
exceed two thousand five hundred ($2,500.00) dollars.

                  (d) Before proceeding with any Alteration that will cost more
than $50,000 (exclusive of the costs of decorating work and items constituting
Tenant's Property), as estimated by a reputable contractor designated by
Landlord, Tenant shall furnish to Landlord one of the following (as selected by
Landlord): (i) a cash deposit, (ii) a performance bond and a labor and materials
payment bond (issued by a corporate surety licensed to do business in New York
reasonably satisfactory to Landlord) or (iii) an irrevocable, unconditional,
negotiable letter of credit, issued by a bank and in a form satisfactory to
Landlord; each to be equal to 125% of the cost of the Alteration, estimated as
set forth above. Any such letter of credit shall be for one year and shall be
renewed by Tenant each and every year until the Alteration in question is
completed and shall be delivered to Landlord not less than 30 days prior to the
expiration of the then current letter of credit, failing which Landlord may
present the then current letter of credit for payment. Upon (A) the completion
of the Alteration in accordance with the terms of this Section 4.02 and (B) the
submission to Landlord of (x) proof evidencing the payment in full for said
Alteration, (y) written unconditional lien waivers of mechanics' liens and other
liens on the Project from all Contractors performing said Alteration and (z) all
submissions required pursuant to Laws, the security deposited with Landlord (or
the balance of the proceeds thereof, if Landlord has drawn on the same) shall be
returned to Tenant. Upon Tenant's failure properly to perform, complete and
fully pay for any Alteration, as determined by Landlord, Landlord may, upon
notice to Tenant, draw on the security deposited under this Section 4.02(d) to
the extent Landlord deems necessary in connection with said Alteration, the
restoration and/or protection of the Premises or the Project and the payment of
any costs, damages or expenses resulting therefrom.

<PAGE>

                  (e) Tenant shall obtain (and furnish copies to Landlord of)
all necessary governmental permits and certificates for the commencement and
prosecution of Alterations and for final approval thereof upon completion, and
shall cause Alterations to be performed in compliance therewith, and in
compliance with all Laws and with the Alteration Plans approved by Landlord.
Landlord agrees, at Tenant's cost and expense, to cooperate with Tenant and
Tenant's architect and engineer in providing information needed for the
preparation of Tenant's Alteration Plans, the application for a building permit,
if necessary, and the application for all other permits required for Tenant's
Alteration Plans, and to promptly execute all documents required to be signed by
Landlord. Alterations shall be diligently performed in a good and workmanlike
manner, using new materials and equipment at least equal in quality and class to
the then standards for the Building established by Landlord. Alterations shall
be performed by Contractors first approved by Landlord (which approval shall not
be unreasonably withheld or delayed); provided, that any Alterations in or to
the systems of the Building shall be performed only by the Contractor(s)
designated by Landlord. With respect to such Contractors for Building systems
(other than heat, ventilation and air conditioning, fire and safety), the
Contractor(s) designated by Landlord shall demonstrate to the reasonable
satisfaction of Tenant that the cost of the work in question is competitively
priced. The performance of any Alteration shall not be done in a manner which
would violate Landlord's union contracts affecting the Project, or create any
work stoppage, picketing, labor disruption, disharmony or dispute or any
interference with the business of Landlord or any tenant or occupant of the
Building. Tenant shall immediately stop the performance of any Alteration if
Landlord notifies Tenant that continuing such Alteration would violate
Landlord's union contracts affecting the Project, or create any work stoppage,
picketing, labor disruption, disharmony or dispute or any interference with the
business of Landlord or any tenant or occupant of the Building.

                  (f) Throughout the performance of Alterations, Tenant shall
carry worker's compensation insurance in statutory limits, "all risk" Builders
Risk coverage and general liability insurance, with completed operation
endorsement, for any occurrence in or about the Project, under which Landlord
and its agent and any Superior Lessor and Superior Mortgagee whose name and
address have been furnished to Tenant shall be named as parties insured, in such
limits as Landlord may reasonably require, with insurers reasonably satisfactory
to Landlord. Tenant shall furnish Landlord with evidence that such insurance is
in effect at or before the commencement of Alterations and, on request, at
reasonable intervals thereafter during the continuance of Alterations.

                  (g) Should any mechanics' or other liens be filed against any
portion of the Project by reason of the acts or omissions of, or because of a
claim against, Tenant or anyone claiming under or through Tenant, Tenant shall
cause the same to be canceled or discharged of record by bond or otherwise
within 30 days after notice from Landlord. If Tenant shall fail to cancel or
discharge said lien or liens within said 30 day period, Landlord may cancel or
discharge the same and, upon Landlord's demand, Tenant shall reimburse Landlord
for all costs incurred in canceling or discharging such liens, together with
interest thereon at the Interest Rate from the date incurred by Landlord to the
date of payment by Tenant, such reimbursement to be made within 10 days after
receipt by Tenant of a written statement from Landlord as to the amount of such
costs. Tenant shall indemnify and hold Landlord harmless from and against all
costs (including, without limitation, attorneys' fees and disbursements and
costs of suit), losses,

                                     - 23 -

<PAGE>

liabilities or causes of action arising out of or relating to any Alteration,
including, without limitation, any mechanics' or other liens asserted in
connection with such Alteration, unless such costs, losses, liabilities or
causes of action result solely from the willful negligence of Landlord or
Landlord's agents.

                  (h) Tenant shall deliver to Landlord, within 30 days after the
completion of an Alteration, five sets of "as-built" drawings thereof prepared
and certified by Tenant's architect. During the Term, Tenant shall keep records
of Material Alterations including plans and specifications, copies of contracts,
invoices, evidence of payment and all other records customarily maintained in
the real estate business relating to Alterations and the cost thereof and shall,
within 30 days after demand by Landlord, furnish to Landlord copies of such
records.

                  (i) All Alterations to and Fixtures installed by Tenant in the
Premises shall be fully paid for by Tenant in cash and shall not be subject to
conditional bills of sale, chattel mortgages, or other title retention
agreements.

                  (j) [INTENTIONALLY OMITTED]

            4.03 Landlord's and Tenant's Property. (a) All fixtures, equipment,
improvements and appurtenances attached to (so that any such fixtures,
equipment, improvements and appurtenances are incorporated into the Premises) or
built into the Premises, whether or not at the expense of Tenant (collectively,
"Fixtures"), shall be and remain a part of the Premises and shall not be removed
by Tenant. All Fixtures constituting Improvements and Betterments shall be the
property of Tenant during the Term and, upon expiration or earlier termination
of this Lease, shall become the property of Landlord. All Fixtures other than
Improvements and Betterments shall, upon installation, be the property of
Landlord. "Improvements and Betterments" means (i) all Fixtures, if any,
installed at the expense of Tenant, whether installed by Tenant or by Landlord
(i.e., excluding any Fixtures paid for by Landlord directly or by way of an
allowance) and (ii) all carpeting in the Premises.

                  (b) All movable partitions, business and trade fixtures,
machinery and equipment, and all furniture, furnishings and other articles of
movable personal property owned by Tenant and located in the Premises
(collectively, "Tenant's Property") shall be and shall remain the property of
Tenant and may be removed by Tenant at any time during the Term; provided, that
if any Tenant's Property is removed, Tenant shall repair any damage to the
Premises or to the Building resulting from the installation and/or removal
thereof. Notwithstanding the foregoing, any equipment or other property
identified in this Lease or in any leasehold improvement agreement as having
been paid for with any allowance or credit granted by Landlord to Tenant shall
not be considered Tenant's Property and shall be and remain a part of the
Premises, shall, upon the expiration or earlier termination of this Lease, be
the property of Landlord and shall not be removed by Tenant.

                  (c) At or before the Expiration Date, or within 15 days after
any earlier termination of this Lease, Tenant, at Tenant's expense, shall remove
Tenant's Property from the Premises (except such items thereof as Landlord shall
have expressly permitted to remain, which shall become the property of
Landlord), and Tenant shall repair any damage to the Premises or the

                                     - 24 -

Building resulting from any installation and/or removal of Tenant's Property.
Any items of Tenant's Property which remain in the Premises after the Expiration
Date, or more than 15 days after an earlier termination of this Lease, may, at
the option of Landlord, be deemed to have been abandoned, and may be retained by
Landlord as its property or disposed of by Landlord, without accountability, in
such manner as Landlord shall determine, at Tenant's expense.

                  (d) With respect to Tenant's Initial Improvements and Tenant's
Expansion Space Alterations, as well as any other Alterations made pursuant to
this Article 4 during the Term of this Lease, Landlord, by notice given to
Tenant at any time prior to the Expiration Date or not later than 30 days after
any earlier termination of this Lease, may require Tenant, notwithstanding
Section 4.03(a), to remove all or any Fixtures that do not constitute a standard
office installation, such as, by way of example only, kitchens, vaults, safes,
raised flooring and interior stairwells; provided, however, that the removal of
all or any Fixtures that constitute a standard office installation shall be
governed by Section 4.02(b) above. If Landlord shall give such notice, then
Tenant, at Tenant's expense, prior to the Expiration Date, or, in the case of an
earlier termination of this Lease, within 15 days after the giving of such
notice by Landlord, shall remove the same from the Premises, shall repair and
restore the Premises to the condition existing prior to installation thereof and
shall repair any damage to the Premises or to the Building due to such removal.

            4.04 Access and Changes to Building. (a) Landlord reserves the
right, at any time, to make changes in or to the Project as Landlord may deem
necessary or desirable, and Landlord shall have no liability to Tenant therefor,
provided any such change does not deprive Tenant of access to the Premises and
does not affect the nature of the Project. Landlord may install and maintain
pipes, fans, ducts, wires and conduits within or through the walls, floors or
ceilings of the Premises. In exercising its rights under this Section 4.04,
Landlord shall use reasonable efforts to minimize any interference with Tenant's
use of the Premises for the ordinary conduct of Tenant's business and Landlord
shall use reasonable efforts to cooperate with Tenant to minimize the visual
appearance of any such pipes, fans, ducts, wires and conduits placed in the
ceiling of the Original Premises. Tenant shall not have any easement or other
right in or to the use of any door or any passage or any concourse or any plaza
connecting the Building with any subway or any other building or to any public
conveniences, and the use of such doors, passages, concourses, plazas and
conveniences may, without notice to Tenant, be regulated or discontinued at any
time by Landlord.

                  (b) Except for the space within the inside surfaces of all
walls, hung ceilings, floors, windows and doors bounding the Premises, all of
the Building, including, without limitation, exterior Building walls, core
corridor walls and doors and any core corridor entrance, any terraces or roofs
adjacent to the Premises, and any space in or adjacent to the Premises used for
shafts, stacks, pipes, conduits, fan rooms, ducts, electric or other utilities,
sinks or other Building facilities, and the use thereof as well as access
thereto through the Premises, are reserved to Landlord and are not part of the
Premises. Landlord reserves the right to name the Building and to change the
name or address of the Building at any time and from time to time.

                  (c) Landlord shall have no liability to Tenant if at any time
any windows of the Premises are either temporarily darkened or obstructed by
reason of any repairs,

                                     - 25 -

<PAGE>

improvements, maintenance and/or cleaning in or about the Building (or
permanently darkened or obstructed if required by Law) or covered by any
translucent material for the purpose of energy conservation, or if any part of
the Building, other than the Premises, is temporarily or permanently closed or
inoperable.

                  (d) Landlord and persons authorized by Landlord shall have the
right, upon prior notice to Tenant (except in an emergency), to enter the
Premises (together with any necessary materials and/or equipment), to inspect or
perform such work as Landlord may reasonably deem necessary or to exhibit the
Premises to prospective purchasers or others or for any other purpose as
Landlord may deem necessary or desirable and, during Business Hours during the
last 18 months of the Term, to prospective tenants. Landlord shall have no
liability to Tenant by reason of any such entry. Landlord shall not be required
to make any improvements or repairs of any kind or character to the Premises
during the Term, except as otherwise set forth in this Lease.

            4.05 Repairs. Tenant shall keep the Premises (including, without
limitation, all Fixtures) in good condition and, upon expiration or earlier
termination of the Term, shall surrender the same to Landlord in the same
condition as when first occupied, reasonable wear and tear excepted. Tenant's
obligation shall include, without limitation, the obligation to repair all
damage caused by Tenant, its agents, employees, invitees and licensees to the
equipment and other installations in the Premises or anywhere in the Building.
Any maintenance, repair or replacement to the windows (including, without
limitation, any solar film attached thereto), the Building systems, the
Building's structural components or any areas outside the Premises and which is
Tenant's obligation to perform shall be performed by Landlord at Tenant's
expense. Tenant shall not commit or allow to be committed any waste or damage to
any portion of the Premises or the Building.

            4.06 Compliance with Laws. (a) Tenant shall comply with all laws,
ordinances, rules, orders and regulations (present, future, ordinary,
extraordinary, foreseen or unforeseen) of any governmental, public or
quasi-public authority and of the New York Board of Underwriters, the New York
Fire Insurance Rating Organization and any other entity performing similar
functions, at any time duly in force (collectively "Laws"), attributable to any
work, installation, occupancy, use or manner of use by Tenant of the Premises or
any part thereof. Nothing contained in this Section 4.06 shall require Tenant to
make any structural changes unless the same are necessitated by reason of the
use by Tenant of the Premises in a manner or for purposes other than normal and
customary ordinary office purposes. Tenant shall procure and maintain all
licenses and permits required for its business.

                  (b) Anything contained in this Lease to the contrary
notwithstanding, as part of Tenant's Initial Improvements, Tenant shall perform
all work and make all installations necessary in order to fully sprinkler the
Premises in compliance with the provisions of Local Law 5 of the New York City
Administrative Code, as approved January 18, 1973, as amended from time to time
(whether or not the Building is sprinklered or required to be sprinklered by
such law).

                  (c) Except to the extent the same is Tenant's responsibility
pursuant to Section 4.06(a) or (b) above or elsewhere in this Lease, Landlord
shall comply with all Laws applicable to the common areas of the Building
generally made available to tenants of the Building, but only if Tenant's use of
the Premises shall be materially and adversely affected by non-compliance
therewith, subject to Landlord's right to contest the applicability or legality
of such Laws.

                  (d) Solely with respect to the 19th Floor and the First
Temporary Space, Landlord hereby represents to Tenant that, as of the date of
this Lease, to its knowledge, without due inquiry, all base building systems,
including the elevator cab and elevator system upgrades and the renovation of
the building lobby, are in compliance with or are exempt from such compliance
under the Americans with Disabilities Act ("ADA").

                  (e) Solely with respect to the Original Premises and the First
Temporary Space, Landlord hereby represents to Tenant that, as of the date of
this Lease, to its knowledge, without due inquiry, the sprinkler system
servicing the Premises is in good-working order and is in compliance with the
provisions of Local Law 5 of the New York City Administrative Code, as approved
on January 18, 1973 and as amended from time to time and with the provisions of
any other applicable rules and regulations of the City of New York.

                  (f) Landlord hereby represents to Tenant that, as of the date
of this Lease, to its knowledge, without due inquiry, there are no Hazardous
Materials, as hereinafter defined, in the Original Premises or the First
Temporary Space. "Hazardous Materials," as used herein, shall mean any
flammables, explosives, radioactive materials, hazardous wastes, hazardous and
toxic substances or related materials, asbestos or any materials containing
asbestos, or any other substance or materials as defined by any Federal, state
or local environmental law, ordinance, rule or regulation, including, without
limitation, the Comprehensive Environmental Response Liability Act, as amended,
the Resource Conservation and Recovery Act, as amended, and in the regulations
adopted and publications promulgated pursuant to each of the foregoing, except
that the term "Hazardous Materials" shall not include any such materials in
amounts typically found in office buildings of a similar age and character as
Building A.

                  (g) Solely with respect to the 19th Floor and the First
Temporary Space, Landlord represents to Tenant that, as of the date of this
Lease, to its knowledge, without due inquiry, Landlord has not received any
notice of violations from the New York City Department of Buildings, which
violations, if present, would prevent Tenant from performing Tenant's Initial
Improvements or from operating in the 19th Floor or the First Temporary Space as
permitted under this Lease.

                  (h) Except to the extent the same is Tenant's responsibility
pursuant to Section 4.06(a) or (b) above or elsewhere in this Lease, Landlord
shall comply with all Laws in effect as of the Possession Date applicable to the
Original Premises prior to giving Tenant vacant possession of the Original
Premises.

            4.07 Tenant Advertising. Tenant shall not use, and shall cause each
of its Affiliates not to use, the name or likeness of the Building or the
Project in any advertising (by whatever medium) without Landlord's consent (not
to be unreasonably withheld or delayed).

            4.08 Right to Perform Tenant Covenants. If Tenant fails to perform
any of its obligations under this Lease, Landlord, any Superior Lessor or any
Superior Mortgagee (each, a "Curing Party") may perform the same at the expense
of Tenant (a) immediately and without notice in the case of emergency or in case
such failure interferes with the use of space by any other tenant in the
Building or with the efficient operation of the Building or may result in a
violation of any Law or in a cancellation of any insurance policy maintained by
Landlord and (b) in any other case if such failure continues beyond any
applicable grace period. If a Curing Party performs any of Tenant's obligations
under this Lease, Tenant shall pay to Landlord (as Additional Charges) the costs
thereof, together with interest at the Interest Rate from the date incurred by
the Curing Party until paid by Tenant, within 10 days after receipt by Tenant of
a statement as to the amounts of such costs. If the Curing Party effects such
cure by bonding any lien which Tenant is required to bond or otherwise
discharge, Tenant shall obtain and substitute a bond for the Curing Party's bond
and shall reimburse the Curing Party for the cost of the Curing Party's bond.

            4.09 Improvements to Temporary Space. (a) Landlord, at Landlord's
expense, has performed in the First Temporary Space the work described on
Exhibit G ("Landlord's Temporary Space Work") in accordance with the provisions
thereof. On the First Temporary Space Occupancy Date, Tenant shall accept the
First Temporary Space in its "as is" condition on such date. All other
improvements to the First Temporary Space which do not constitute Landlord's
Temporary Space Work shall be performed by Tenant at Tenant's expense in
accordance with Section 4.02 or, if applicable, in accordance with Section 1.08.

                  (b) If applicable, Landlord, at Landlord's expense, shall
perform or cause to be performed in the Second Temporary Space, Landlord's
Temporary Space Work in accordance with the provisions of Exhibit G. All initial
improvements to the Second Temporary Space which do not constitute Landlord's
Temporary Space Work shall be performed by Tenant at Tenant's expense in
accordance with Section 4.02.

                            Assignment and Subletting

            5.01 Assignment; Etc. (a) Subject to Section 5.02, and except as
expressly set forth otherwise in this Article 5, neither this Lease nor the term
and estate hereby granted, nor any part hereof or thereof shall be assigned,
mortgaged, pledged, encumbered or otherwise transferred voluntarily,
involuntarily, by operation of law or otherwise, and neither the Premises, nor
any part thereof shall be subleased, be licensed, be used or occupied by any
person or entity other than Tenant or be encumbered in any manner by reason of
any act or omission on the part of Tenant, and no rents or other sums receivable
by Tenant under any sublease of all or any part of

                                     - 28 -

<PAGE>

the Premises shall be assigned or otherwise encumbered, without the prior
consent of Landlord. The dissolution or direct or indirect transfer of control
of Tenant (however accomplished including, by way of example, the admission of
new partners or members or withdrawal of existing partners or members, or
transfers of interests in distributions of profits or losses of Tenant, issuance
of additional stock, redemption of stock, stock voting agreement, or change in
classes of stock) shall be deemed an assignment of this Lease regardless of
whether the transfer is made by one or more transactions, or whether one or more
persons or entities hold the controlling interest prior to the transfer or
afterwards. An agreement under which another person or entity becomes
responsible for all or a portion of Tenant's obligations under this Lease shall
be deemed an assignment of this Lease. No assignment or other transfer of this
Lease and the term and estate hereby granted, and no subletting of all or any
portion of the Premises shall relieve Tenant of its liability under this Lease
or of the obligation to obtain Landlord's prior consent to any further
assignment, other transfer or subletting. Any attempt to assign this Lease or
sublet all or any portion of the Premises in violation of this Article 5 shall
be null and void.

                  (b) Notwithstanding Section 5.01(a), without the consent of
Landlord, this Lease may be assigned to (i) an entity created by merger,
reorganization or recapitalization of or with Tenant or (ii) a purchaser of all
or substantially all of Tenant's assets; provided, in the case of both clause
(i) and clause (ii), that (A) Landlord shall have received a notice of such
assignment from Tenant, (B) the assignee assumes by written instrument
reasonably satisfactory to Landlord all of Tenant's obligations under this
Lease, (C) such assignment is for a valid business purpose and not to avoid any
obligations under this Lease, and (D) the assignee shall have, immediately after
giving effect to such assignment, a NAV that is at least equal to the greater of
(i) the NAV shown on Exhibit K attached hereto and made a part hereof or (ii)
the NAV of the Tenant named herein (i.e., ACTV, Inc.) at the time of such
assignment.

                  (c) Notwithstanding Section 5.01(a), without the consent of
Landlord, Tenant may assign this Lease or sublet all or any part of the Premises
to an Affiliate of Tenant; provided, that (i) Landlord shall have received a
notice of such assignment or sublease from Tenant; and (ii) in the case of any
such assignment. (A) the assignment is for a valid business purpose and not to
avoid any obligations under this Lease, and (B) the assignee assumes by written
instrument reasonably satisfactory to Landlord all of Tenant's obligations under
this Lease. "Affiliate" means, any person or entity which controls or is
controlled by Tenant. "Control" means ownership or voting control by Tenant,
directly or indirectly, of 51% or more of the voting stock, partnership
interests or other beneficial ownership interests of the entity in question. The
transfer of the outstanding capital stock of any corporate Tenant (by persons or
parties other than "insiders" within the meaning of the Securities Exchange Act
of 1934, as amended) through the "over-the-counter" market or any recognized
national securities exchange shall not be considered in the determination of
whether control has been transferred.

                  (d) Tenant represents to Landlord that, as of the date of this
Lease, the financial statement attached hereto as Exhibit K (the "Financial
Statement") is a true and correct statement of Tenant's NAV as of the date
thereof Simultaneously with the delivery of the Expansion Notice to Landlord in
accordance with Section 10.01, Tenant shall deliver a secretary's certificate to
Landlord attaching thereto a true and correct statement of Tenant's NAV dated no
earlier than sixty (60) days prior to the date of the Expansion Notice ("Updated
Financial

                                     - 29 -

<PAGE>

Statement"). If Tenant's NAV as set forth in the Updated Financial Statement is
not at least 60% of Tenant's NAV on the date set forth in the Financial
Statement, Landlord shall have the right to terminate this Lease upon notice to
Tenant given within thirty (30) days of receipt of Tenant's Updated Financial
Statement. Such notice shall set forth a date for termination of this Lease,
which date shall be no sooner than 90 days and no later than 120 days from the
date of such notice.

            5.02 Landlord's Option Right. (a) If Tenant desires to assign this
Lease or sublet all or a portion of the Premises (other than in accordance with
Sections 5.01(b) or 5.01(c)), Tenant shall give to Landlord notice ("Tenant's
Offer Notice") thereof, specifying (i) in the case of a proposed subletting, the
location of the space to be sublet and the terms of the subletting of such
space, (ii) (A) in the case of a proposed assignment, Tenant's good faith offer
of the consideration Tenant desires to receive or pay for such assignment or (B)
in the case of a proposed subletting, Tenant's good faith offer of the fixed
annual rent which Tenant desires to receive for such proposed subletting
(assuming that a subtenant will pay for Taxes, expense escalations and
electricity as described in Article 2 herein in the same manner, and utilizing
the same base year or base amount, as Tenant pays for such amounts under this
Lease) and (iii) the proposed assignment or sublease commencement date.

                  (b) Tenant's Offer Notice shall be deemed an offer from Tenant
to Landlord whereby Landlord (or Landlord's designee) may, at Landlord's option,
(i) sublease such space from Tenant or (ii) have this Lease assigned to it or
terminate this Lease (if the proposed transaction is an assignment or a sublease
of all or substantially all of the Premises or a sublease of a portion of the
Premises which, when aggregated with other subleases then in effect, covers all
or substantially all of the Premises). Said option may be exercised by Landlord
by notice to Tenant within 45 days after a Tenant's Offer Notice, together with
all information required pursuant to Section 5.02(a), has been given by Tenant
to Landlord.

                  (c) If Landlord exercises its option under Section 5.02(b)(ii)
to terminate this Lease, then this Lease shall terminate on the proposed
assignment or sublease commencement date specified in the applicable Tenant's
Offer Notice and all Rent shall be paid and apportioned to such date.

                  (d) If Landlord exercises its option under Section 5.02(b)(ii)
to have this Lease assigned to it (or its designee), then Tenant shall assign
this Lease to Landlord (or Landlord's designee) by an assignment in form and
substance reasonably satisfactory to Landlord, effective on the proposed
assignment or sublease commencement date specified in the applicable Tenant's
Offer Notice. Tenant shall not be entitled to consideration or payment from
Landlord (or Landlord's designee) in connection with any such assignment. If the
Tenant's Offer Notice provides that Tenant will pay any consideration or grant
any concessions in connection with the proposed assignment, then Tenant shall
pay such consideration and/or grant any such concessions to Landlord (or
Landlord's designee) on the date Tenant assigns this Lease to Landlord (or
Landlord's designee).

                  (f) If Landlord exercises its option under Section 5.02(b)(i)
to sublet the Premises, such sublease to Landlord or its designee (as subtenant)
shall be in form and substance reasonably satisfactory to Landlord at the lower
of (i) the rental rate per rentable square foot of Fixed Rent and Additional
Charges then payable pursuant to this Lease or (ii) the rental set forth in the
applicable Tenant's Offer Notice with respect to such sublet space, and shall be
for the term set forth in the applicable Tenant's Offer Notice, and:

                        (A) shall be subject to all of the terms and conditions
of this Lease except such as are irrelevant or inapplicable, and except as
otherwise expressly set forth to the contrary in this Section 5.02(f);

                        (B) shall be upon the same terms and conditions as those
contained in the applicable Tenant's Offer Notice and otherwise on the terms and
conditions of this Lease, except such as are irrelevant or inapplicable and
except as otherwise expressly set forth to the contrary in this Section 5.02(f);

                        (C) shall permit the sublessee, without Tenant's

consent, freely to assign such sublease or any interest therein or to sublet all
or any part of the space covered by such sublease and to make any and all
alterations and improvements in the space covered by such sublease;

                        (D) shall provide that any assignee or further subtenant
of Landlord or its designee may, at the election of Landlord, make alterations,
decorations and installations in such space or any part thereon any or all of
which may be removed, in whole or in part, by such assignee or subtenant, at its
option, prior to or upon the expiration or other termination of such sublease,
provided that such assignee or subtenant, at its expense, shall repair any
damage caused by such removal; and

                        (E) shall provide that (1) the parties to such sublease
expressly negate any intention that any estate created under such sublease be
merged with any other estate held by either of said parties, (2) any assignment
or subletting by Landlord or its designee (as the subtenant) may be for any
purpose or purposes that Landlord shall deem appropriate, (3) Landlord, at
Tenant's expense, may make such alterations as may be required or deemed
necessary by Landlord to demise separately the subleased space and to comply
with any Laws relating to such demise, and (4) at the expiration of the term of
such sublease, Tenant shall accept the space covered by such sublease in its
then existing condition, subject to the obligations of the sublessee to make
such repairs thereto as may be necessary to preserve such space in good order
and condition.

                  (g) If Landlord exercises its option under Section 5.02(b)(i)
to sublet the Premises (or to have the Premises sublet to its designee) or if
Landlord exercises its option under Section 5.02(b)(ii) to have this Lease
assigned to it (or its designee) then Tenant shall not have any liability
hereunder arising from, in connection with or relating to any default of such
sublessee or assignee including, without limitation, the failure by such
sublessee or assignee to pay any rent due thereunder (but such release of Tenant
shall not operate to relieve the assignee from any liability for which Tenant
should otherwise be liable).

                  (h) In the case of a proposed sublease, Tenant shall not
sublet any space to a third party at a rental which is less (on a per rentable
square foot basis) than the rental (on a per rentable square foot basis)
specified in Tenant's Offer Notice with respect to such space, without complying
once again with all of the provisions of this Section 5.02 and re-offering such
space to Landlord at such lower rental. In the case of a proposed assignment,
Tenant shall not assign this Lease to a third party where Tenant pays greater
consideration or grants a greater concession to such third party for such
assignment than the consideration offered to be paid or concession offered to be
granted to Landlord in Tenant's Offer Notice without complying once again with
all of the provisions of this Section 5.02 and re-offering to assign this Lease
to Landlord and pay such consideration or grant such concession to Landlord.

                  (i) If Landlord fails to respond to Tenant's Offer Notice
within the 45 days after such Tenant's Offer Notice, together with all
information required pursuant to Section 5.02(a), has been given by Tenant to
Landlord, Landlord shall be deemed to have declined Tenant's offer; provided,
that 15 days prior to the expiration of such 45 day period, Tenant shall send a
second notice to Landlord with the phrase "Failure to respond shall be deemed to
be a waiver of Landlord's Option Right under Section 5.02 of the Lease" in bold
lettering at the top of such notice.

                  (i) Landlord acknowledges and agrees that the foregoing
provisions of Section 5.02 shall not apply to an assignment subject to Section
5.01(b) and Section 5.01(c) above.

            5.03 Assignment and Subletting Procedures. (a) If Tenant delivers to
Landlord a Tenant's Offer Notice with respect to any proposed assignment of this
Lease or subletting of all or any portion of the Premises and Landlord does not
timely exercise any of its options under Section 5.02, and Tenant thereafter
desires to assign this Lease or sublet the Premises as specified in Tenant's
Offer Notice, Tenant shall notify Landlord (a "Transfer Notice") of such desire,
which notice shall be accompanied by (i) a copy of the proposed assignment or
sublease and all related agreements, the effective date of which shall be at
least 30 days after the giving of the Transfer Notice, (ii) a statement setting
forth in reasonable detail the identity of the proposed assignee or subtenant,
the nature of its business and its proposed use of the Premises, (iii) current
financial information with respect to the proposed assignee or subtenant,
including, without limitation, its most recent financial statement and (iv) such
other information as Landlord may reasonably request, and Landlord's consent to
the proposed assignment or sublease shall not be unreasonably withheld, delayed
or conditioned provided that:

                        (i) Such Transfer Notice shall be delivered to Landlord
within three months after the delivery to Landlord of the applicable Tenant's
Offer Notice.

                        (ii) In Landlord's reasonable judgment the proposed
assignee or subtenant will use the Premises in a manner that (A) is in keeping
with the then standards of the Building, (B) is limited to the use expressly
permitted under this Lease, and (C) will not violate any negative covenant then
in effect as to use contained in any other Lease of space in the Building.

                        (iii) The proposed assignee or subtenant is, in
Landlord's reasonable judgment, a reputable person or entity of good character
and with sufficient financial worth considering the responsibility involved.

                        (iv) Neither the proposed assignee or sublessee, nor any
Affiliate of such assignee or sublessee, is then an occupant of any part of the
Building.

                        (v) The proposed assignee or sublessee is not a person
with whom Landlord is then actively negotiating or has within the prior 3 months
negotiated to lease space in the Building.

                        (vi) The form of the proposed sublease shall be
reasonably satisfactory to Landlord and shall comply with the applicable
provisions of this Article 5.

                        (vii) There shall not be more than 1 subtenant of the
Original Premises and I subtenant of the Expansion Space and each such sublease
shall not be for less than 5,000 rentable square feet.

                        (viii) The aggregate rent to be paid by the proposed
subtenant is not less than the fair rental value of the sublet space as sublet
space (as reasonably determined by Landlord).

                        (ix) Tenant shall reimburse Landlord on demand for any
reasonable out-of-pocket costs incurred by Landlord in connection with said
assignment or sublease, including, without limitation, the costs of making
investigations as to the acceptability of the proposed assignee or subtenant,
and legal costs incurred in connection with the granting of any requested
consent.

                  If Landlord denies Landlord's consent to the proposed
assignment or sublease under this Section 5.03(a), Landlord shall specify the
reasons for such denial, provided, however, that Landlords' failure to so
specify such reasons shall not impose upon Landlord any obligation to consent to
such proposed assignment or sublease nor result in any liability to Landlord in
respect thereof.

                  (b) If Landlord consents to a proposed assignment or sublease
and Tenant fails to execute and deliver the assignment or sublease to which
Landlord consented within 45 days after the giving of such consent, then Tenant
shall again comply with this Article 5 before assigning this Lease or subletting
all or part of the Premises.

                  (c) If Landlord fails to respond to a Transfer Notice within
35 days after such Transfer Notice, together with all information required
pursuant to Section 5.03(a), has been given by Tenant to Landlord, Landlord
shall be deemed to have consented to such proposed assignment or subletting;
provided, that 5 days prior to the expiration of such 35 day period, Tenant
shall send a second notice to Landlord with the phrase "Failure to respond shall
be deemed consent to the assignment or subletting proposed in Tenant's Transfer
Notice" in bold lettering at the top of such notice.

                  (d) If Tenant delivers to Landlord a Transfer Notice, together
with all information required under Section 5.03(a) above, at the same time that
Tenant delivers Tenant's Offer Notice as required under Section 5.02 above, then
Landlord shall either (i) exercise its options under Section 5.02 or (ii)
approve or deny (and, in the case of a denial, specifying the reasons for such
denial; subject to the last sentence of subsection (a) above,) Tenant's request
to assign this Lease or sublet the Premises under the provisions of Section 5.03
within 45 days after Tenant's Offer Notice, together with all information
required pursuant to Section 5.02(a), and the Transfer Notice, together with all
information required pursuant to Section 5.03(a), have been given by Tenant to
Landlord. If Landlord fails to respond within 45 days after receiving Tenant's
Offer Notice, together with all information required pursuant to Section 5.02(a)
and the Transfer Notice, together with all information required pursuant to
Section 5.03(b), Landlord shall be deemed to have consented to such proposed
assignment or subletting; provided, that 15 days prior to the expiration of such
45 day period, Tenant shall send a second notice to Landlord with the phrase
"Failure to respond shall be deemed to be a waiver of Landlord's Option Right
under Section 5.02 of the Lease and consent to the assignment or subletting
proposed in Tenant's Transfer Notice (such Tenant's Office Notice and Transfer
Notice having been delivered simultaneously)" in bold lettering at the top of
such notice.

            5.04 General Provisions. (a) If this Lease is assigned, whether or
not in violation of this Lease, Landlord may collect rent from the assignee. If
the Premises or any part thereof are sublet or occupied by anybody other than
Tenant, whether or not in violation of this Lease, Landlord may, after default
by Tenant, and expiration of Tenant's time to cure such default, collect rent
from the subtenant or occupant. In either event, Landlord may apply the net
amount collected against Rent, but no such assignment, subletting, occupancy or
collection shall be deemed a waiver of any of the provisions of Section 5.01(a),
or the acceptance of the assignee, subtenant or occupant as tenant, or a release
of Tenant from the performance of Tenant's obligations under this Lease.

                  (b) No assignment or transfer shall be effective until the
assignee delivers to Landlord (i) evidence that the assignee, as Tenant
hereunder, has complied with the requirements of Sections 7.02 and 7.03, and
(ii) an agreement in form and substance satisfactory to Landlord whereby the
assignee assumes Tenant's obligations under this Lease.

                  (c) Notwithstanding any assignment or transfer, whether or not
in violation of this Lease, and notwithstanding the acceptance of any Rent by
Landlord from an assignee, transferee, or any other party, the original named
Tenant and each successor Tenant shall remain fully liable for the payment of
the Rent and the performance of all of Tenant's other obligations under this
Lease. The joint and several liability of Tenant and any immediate or remote
successor in interest of Tenant shall not be discharged, released or impaired in
any respect by any agreement made by Landlord extending the time to perform, or
otherwise modifying, any of the obligations of Tenant under this Lease, or by
any waiver or failure of Landlord to enforce any of the obligations of Tenant
under this Lease.

                  (d) Each subletting by Tenant shall be subject to the
following:

                                     - 34 -

<PAGE>

                        (i) No subletting shall be (x) for a term (including any
renewal or extension options contained in the sublease) ending later than one
day prior to the Expiration Date or (y) for less than (A) 5,000 rentable square
feet in the Original Premises and (B) 4,000 rentable square feet in the
Expansion Space except for subleases to Affiliates. Tenant shall not be
permitted to have more than one (1) subtenant of the Premises at any time;
provided, however, that if Tenant exercises Tenant's Expansion Option, Tenant
shall be permitted to have no more than one (1) subtenant in the Expansion Space
and no more than one (1) subtenant (other than Affiliates) in the Original
Premises at any time.

                        (ii) No sublease shall be valid, and no subtenant shall
take possession of the Premises or any part thereof, until there has been
delivered to Landlord, both (A) an executed counterpart of such sublease, and
(B) a certificate of insurance evidencing that (x) Landlord is an additional
insured under the insurance policies required to be maintained by occupants of
the Premises pursuant to Section 7.02, and (y) there is in full force and
effect, the insurance otherwise required by Section 7.02.

                        (iii) Each sublease shall provide that it is subject and
subordinate to this Lease, and that in the event of termination, reentry or
dispossess by Landlord under this Lease, Landlord may, at its option, take over
all of the right, title and interest of Tenant, as sublessor, under such
sublease, and such subtenant shall, at Landlord's option, attorn to Landlord
pursuant to the then executory provisions of such sublease, except that Landlord
shall not be liable for, subject to or bound by any item of the type that a
Successor Landlord is not so liable for, subject to or bound by in the case of
an attornment by Tenant to a Successor Landlord under Section 6.01(a).

                  (e) Each sublease shall provide that the subtenant may not
assign its rights thereunder or further sublet the space demised under the
sublease, in whole or in part, without complying with all of the terms and
conditions of this Article 5, including, without limitation, Section 5.05, which
for purposes of this Section 5.04(e) shall be deemed to be appropriately
modified to take into account that the transaction in question is an assignment
of the sublease or a further subletting of the space demised under the sublease,
as the case may be.

                  (f) Tenant shall not publicly advertise the availability of
the Premises or any portion thereof as sublet space or by way of an assignment
of this Lease, without first obtaining Landlord's consent, which consent shall
not be unreasonably withheld, conditioned or delayed, provided that Tenant shall
in no event advertise the rental rate or any description thereof.

            5.05 Assignment and Sublease Profits. (a) If the aggregate of the
amounts payable as fixed rent and as additional rent on account of Taxes and
electricity by a subtenant under a sublease of the Premises and the amount of
any Other Sublease Consideration payable to Tenant by such subtenant, whether
received in a lump-sum payment or otherwise, shall be in excess of Tenant's
Basic Cost therefor at that time then, promptly after the collection thereof,
Tenant shall pay to Landlord in monthly installments as and when collected, as
Additional Charges, 50% of such excess. Tenant shall deliver to Landlord within
60 days after the end of each calendar year and within 60 days after the
expiration or earlier termination of this Lease a statement specifying each
sublease in effect during such calendar year or partial calendar year, the

                                     - 35 -

<PAGE>

rentable area demised thereby, the term thereof and a computation in reasonable
detail showing the calculation of the amounts paid and payable by the subtenant
to Tenant, and by Tenant to Landlord, with respect to such sublease for the
period covered by such statement. "Tenant's Basic Cost" for sublet space at any
time means the sum of (i) the portion of the Fixed Rent (as escalated pursuant
to Section 2.10 of this Lease) and Tax Payments which is attributable to the
sublet space, plus (ii) the amount payable by Tenant on account of electricity
in respect of the sublet space, plus (iii) the amount of any costs reasonably
incurred by Tenant in making changes in the layout and finish of the sublet
space for the subtenant amortized on a straight-line basis over the term of the
sublease or of Tenant's cash contribution to the subtenant in lieu thereof plus
(iv) the amount of any reasonable brokerage commissions and reasonable legal
fees paid by Tenant in connection with the sublease amortized on a straight-line
basis over the term of the sublease. "Other Sublease Consideration" means all
sums paid for the furnishing of services by Tenant and the sale or rental of
Tenant's fixtures, leasehold improvements, equipment, furniture or other
personal property less, in the case of the sale thereof the then net unamortized
or undepreciated cost thereof determined on the basis of Tenant's federal income
tax returns.

                  (b) Upon any assignment of this Lease, Tenant shall pay to
Landlord 50% of the Assignment Consideration received by Tenant for such
assignment, after deducting therefrom customary and reasonable closing expenses.
"Assignment Consideration" means an amount equal to all sums and other
considerations paid to Tenant by the assignee for or by reason of such
assignment (including, without limitation, sums paid for the furnishing of
services by Tenant and the sale or rental of Tenant's fixtures, leasehold
improvements, equipment, furniture, furnishings or other personal property,
less, in the case of a sale thereof the then net unamortized or undepreciated
cost thereof determined on the basis of Tenant's federal income tax returns).

                  (c) This Section 5.05 shall not apply to any assignment or
subletting pursuant to Section 5.01(b) or (c) of this Lease.

                                    ARTICLE 6

                        Subordination; Default; Indemnity

            6.01 Subordination. (a) This Lease is subject and subordinate to
each mortgage (a "Superior Mortgage") and each underlying lease (a "Superior
Lease") which may now or hereafter affect all or any portion of the Project or
any interest therein; provided that the Superior Mortgagee under such Superior
Mortgage or Superior Lessor under such Superior Lease shall have executed and
delivered a non-disturbance and attornment agreement substantially to the effect
that so long as Tenant is not in default hereunder beyond any applicable notice
and grace periods, (i) this Lease will not be terminated or cut off nor shall
Tenant's possession hereunder be disturbed by enforcement of any rights given to
such Superior Mortgagee or Superior Lessor pursuant to such Superior Mortgage or
Superior Lease, and (ii) such Superior Mortgagee or Superior Lessor shall
recognize Tenant as the tenant under this Lease. The lessor under a Superior
Lease is called a "Superior Lessor" and the mortgagee under a Superior Mortgage
is called a "Superior Mortgagee". Tenant shall execute, acknowledge and deliver
any

                                     - 36 -

<PAGE>

instrument reasonably requested by Landlord, a Superior Lessor or Superior
Mortgagee to evidence such subordination, in a form substantially the same as
Exhibit H attached hereto but no such instrument shall be necessary to make such
subordination effective. Notwithstanding anything contained in this Section 6.01
to the contrary, if any Superior Mortgagee or Superior Lessee executes and
delivers a non-disturbance and attornment agreement either (i) in the form
herein described and such agreement is not in any material respect inconsistent
with the provisions of this Lease or (ii) in a form which is not in any material
respect less favorable to Tenant as the non-disturbance and attornment agreement
executed and delivered contemporaneously herewith by Tenant and the existing
Superior Mortgagee or Superior Lessor, as applicable, and Tenant either fails or
refuses to execute and deliver such agreement within 10 days after delivery of
such agreement to Tenant, then this Lease shall automatically and without
further act be deemed to be subject and subordinate to such Superior Mortgage or
Superior Lease and such non-disturbance and attornment agreement shall then be
deemed to be in effect with respect to such Superior Mortgage or Superior Lease.
Tenant acknowledges and agrees that simultaneously herewith Tenant and the
existing Superior Mortgagee and the existing Superior Lessor have executed and
exchanged non-disturbance and attornment agreements which satisfy the
requirements of this Section 6.01. Tenant shall execute any amendment of this
Lease requested by a Superior Mortgagee or a Superior Lessor, provided such
amendment shall not result in a material increase in Tenant's obligations under
this Lease or a material reduction in the benefits available to Tenant. In the
event of the enforcement by a Superior Mortgagee of the remedies provided for by
law or by such Superior Mortgage, or in the event of the termination or
expiration of a Superior Lease, Tenant, upon request of such Superior Mortgagee,
Superior Lessor or any person succeeding to the interest of such mortgagee or
lessor (each, a "Successor Landlord"), shall automatically become the tenant of
such Successor Landlord without change in the terms or provisions of this Lease
(it being understood that Tenant shall, if requested, enter into a new lease on
terms identical to those in this Lease); provided, that any Successor Landlord
shall not be (i) liable for any act, omission or default of any prior landlord
(including, without limitation, Landlord); (ii) liable for the return of any
monies paid to or on deposit with any prior landlord (including, without
limitation, Landlord), except to the extent such monies or deposits are
delivered to such Successor Landlord; (iii) subject to any offset, claims or
defense that Tenant might have against any prior landlord (including, without
limitation, Landlord); (iv) bound by any Rent which Tenant might have paid for
more than the current month to any prior landlord (including, without
limitation, Landlord) unless actually received by such Successor Landlord; (v)
bound by any covenant to perform or complete any construction in connection with
the Project or the Premises or to pay any sums to Tenant in connection
therewith; or (vi) bound by any waiver or forbearance under, or any amendment,
modification, abridgement, cancellation or surrender of, this Lease made without
the consent of such Successor Landlord. Upon request by such Successor Landlord,
Tenant shall execute and deliver an instrument or instruments, reasonably
requested by such Successor Landlord, confirming the attornment provided for
herein, but no such instrument shall be necessary to make such attornment
effective.

                  (b) Tenant shall give each Superior Mortgagee (including Aetna
Life Insurance Company ("Aetna"), Landlord's mortgagee as of the date of this
Lease) and each Superior Lessor a copy of any notice of default served upon
Landlord, provided that Tenant has been notified of the address of such
mortgagee or lessor. If Landlord fails to cure any default as

                                     - 37 -

<PAGE>

to which Tenant is obligated to give notice pursuant to the preceding sentence
within the time provided for in this Lease, then each such mortgagee or lessor
shall have an additional 30 days after receipt of such notice within which to
cure such default or if such default cannot be cured within that time, then such
additional time as may be necessary if within such 30 days, any such mortgagee
or lessor has commenced and is diligently pursuing the remedies necessary to
cure such default (including, without limitation, commencement of foreclosure
proceedings or eviction proceedings, if necessary to effect such cure), in which
event this Lease shall not be terminated and Tenant shall not exercise any other
rights or remedies under this Lease or otherwise while such remedies are being
so diligently pursued. Nothing herein shall be deemed to imply that Tenant has
any right to terminate this Lease or any other right or remedy, except as may be
otherwise expressly provided for in this Lease. The address for Aetna is 151
Farmington Avenue, Hartford, CT 06156-9624.

                  (c) Tenant acknowledges being advised by Landlord that
Landlord's mortgage with Aetna Life Insurance Company contains a provision that
Landlord may not waive any provision of any lease without Aetna's written
consent. This restriction shall be enforceable by Landlord or Aetna or any
future mortgagee whose mortgage contains such provision.

            6.02 Estoppel Certificate. Each party shall, at any time and from
time to time, within 20 days after written request by the other party, which
request shall specifically state the time period in which the other party must
respond, execute and deliver to the requesting party (or to such person or
entity as the requesting party may designate) a statement certifying that this
Lease is unmodified and in full force and effect (or if there have been
modifications, that the same is in full force and effect as modified and stating
the modifications), certifying the Possession Date, Expiration Date and the
dates to which the Fixed Rent and Additional Charges have been paid and stating
whether or not the other party is in default in performance of any of its
obligations under this Lease, and, if so, specifying each such default of which
such party has knowledge, it being intended that any such statement shall be
deemed a representation and warranty to be relied upon by the party to whom such
statement is addressed. The responding party also shall include or confirm in
any such statement such other information concerning this Lease as the other
party may reasonably request.

            6.03 Default. This Lease and the term and estate hereby granted are
subject to the limitation that:

                  (a) if Tenant defaults in the payment of any Rent, and such
default continues for 10 days in the event of a default in the payment of Base
Rent or 15 days in the event of a default in the payment of Additional Rent or
any other sums due hereunder after Landlord gives to Tenant a notice specifying
such default (provided, however, that Tenant acknowledges that Rent shall be due
and payable on the first day of the month, and failure to pay such Rent on or
prior to the first day of any month shall be considered a default under this
Lease and interest shall accrue thereon as provided in Section 2.08 of this
Lease from and after the first day the Rent becomes due and payable), or

                  (b) if Tenant defaults in the keeping, observance or
performance of any covenant or agreement (other than a default of the character
referred to in Section 6.03(a), (c),

                                     - 38 -

<PAGE>

(d), (e) or (f), and if such default continues and is not cured within 30 days
after Landlord gives to Tenant a notice specifying the same, or, in the case of
a default which for causes beyond Tenant's reasonable control cannot with due
diligence be cured within such period of 30 days, if Tenant shall not
immediately upon the receipt of such notice, (i) advise Landlord of Tenant's
intention duly to institute all steps necessary to cure such default and (ii)
institute and thereafter diligently prosecute to completion all steps necessary
to cure the same, or

                  (c) if this Lease or the estate hereby granted would, by
operation of law or otherwise, devolve upon or pass to any person or entity
other than Tenant, except as expressly permitted by Article 5, or

                  (d) if Tenant shall abandon the Premises (and the fact that
any of Tenant's Property remains in the Premises shall not be evidence that
Tenant has not abandoned the Premises), or

                  (e) if Tenant defaults under any other lease with Landlord or
under any other lease in a building managed by Orda Management Corporation which
default shall continue beyond any applicable grace period provided under such
other lease, or

                  (f) if a default of the kind set forth in Section 6.03(a) or
(b) shall occur and have been cured, and if a similar default shall occur more
than once within the next 365 days, whether or not such similar defaults are
cured within the applicable grace period, or

                  (g) if Tenant fails to deliver to Landlord any security
deposit or letter of credit within the time period required under Section 2.09
and, if applicable, Section 10.01, then, in any of such cases, in addition to
any other remedies available to Landlord at law or in equity, Landlord shall be
entitled to give to Tenant a notice of intention to end the Term at the
expiration of 5 days from the date of the giving of such notice, and, in the
event such notice is given, this Lease and the term and estate hereby granted
shall terminate upon the expiration of such 5 days with the same effect as if
the last of such 5 days were the Expiration Date, but Tenant shall remain liable
for damages as provided herein or pursuant to law.

            6.04 Re-entry by Landlord. If Tenant defaults in the payment of any
Rent and such default continues for 5 days, or if this Lease shall terminate as
in Section 6.03 provided, Landlord or Landlord's agents and servants may
immediately or at any time thereafter re-enter into or upon the Premises, or any
part thereof, without notice, either by summary dispossess proceedings or by any
suitable action or proceeding at law, or by legal force or otherwise, without
being liable to indictment, prosecution or damages therefor, and may repossess
the same, and may remove any persons therefrom, to the end that Landlord may
have, hold and enjoy the Premises. The words "re-enter" and "re-entering" as
used in this Lease are not restricted to their technical legal meanings. Upon
such termination or re-entry, Tenant shall pay to Landlord any Rent then due and
owing (in addition to any damages payable under Section 6.05).

                                     - 39 -

<PAGE>

            6.05 Damages. If this Lease is terminated under Section 6.03, or if
Landlord re-enters the Premises under Section 6.04, Tenant shall pay to Landlord
as damages, at the election of Landlord, either:

                  (a) a sum which, at the time of such termination or re-entry,
represents the then value of the excess, if any, of (1) the aggregate of the
Rent which, had this Lease not terminated, would have been payable hereunder by
Tenant for the period commencing on the day following the date of such
termination or re-entry to and including the Expiration Date over (2) the
aggregate fair rental value of the Premises for the same period (for the
purposes of this clause (a) the amount of Additional Charges which would have
been payable by Tenant under Sections 2.04 and 2.05 shall, for each calendar
year ending after such termination or re-entry, be deemed to be an amount equal
to the amount of such Additional Charges payable by Tenant for the calendar year
immediately preceding the calendar year in which such termination or re-entry
shall occur), or

                  (b) sums equal to the Rent that would have been payable by
Tenant through and including the Expiration Date had this Lease not terminated
or had Landlord not re-entered the Premises, payable upon the due dates therefor
specified in this Lease; provided, that if Landlord shall relet all or any part
of the Premises for all or any part of the period commencing on the day
following the date of such termination or re-entry to and including the
Expiration Date, Landlord shall credit Tenant with the net rents received by
Landlord from such reletting, such net rents to be determined by first deducting
from the gross rents as and when received by Landlord from such reletting the
expenses incurred or paid by Landlord in terminating this Lease and of
re-entering the Premises and of securing possession thereof, as well as the
expenses of reletting, including, without limitation, altering and preparing the
Premises for new tenants, brokers' commissions, legal fees and all other
expenses properly chargeable against the Premises and the rental therefrom in
connection with such reletting, it being understood that any such reletting may
be for a period equal to or shorter or longer than said period; provided,
further, that (i) in no event shall Tenant be entitled to receive any excess of
such net rents over the sums payable by Tenant to Landlord under this Lease,
(ii) in no event shall Tenant be entitled, in any suit for the collection of
damages pursuant to this Section 6.05(b), to a credit in respect of any net
rents from a reletting except to the extent that such net rents are actually
received by Landlord prior to the commencement of such suit, (iii) if the
Premises or any part thereof should be relet in combination with other space,
then proper apportionment on a square foot rentable area basis shall be made of
the rent received from such reletting and of the expenses of reletting and (iv)
Landlord shall have no obligation to so relet the Premises and Tenant hereby
waives any right Tenant may have, at law or in equity, to require Landlord to so
relet the Premises.

Suit or suits for the recovery of any damages payable hereunder by Tenant, or
any installments thereof may be brought by Landlord from time to time at its
election, and nothing contained herein shall require Landlord to postpone suit
until the date when the Term would have expired but for such termination or
re-entry.

            6.06 Other Remedies. Nothing contained in this Lease shall be
construed as limiting or precluding the recovery by Landlord against Tenant of
any sums or damages to which, in addition to the damages particularly provided
above, Landlord may lawfully be entitled by

                                     - 40 -

<PAGE>

reason of any default hereunder on the part of Tenant. Anything in this Lease to
the contrary notwithstanding, during the continuation of any default by Tenant,
Tenant shall not be entitled to exercise any rights or options, or to receive
any funds or proceeds being held, under or pursuant to this Lease.

            6.07 Right to Injunction. In the event of a breach or threatened
breach by Tenant of any of its obligations under this Lease, including, but not
limited to, holding over after the Expiration Date or the date of any earlier
termination of this Lease, Landlord shall also have the right of injunction and,
in the case of a threatened holdover, the right to bring a summary proceeding
for possession of the Premises on the Expiration Date or the date of any earlier
termination of this Lease. The specified remedies to which Landlord may resort
hereunder are cumulative and are not intended to be exclusive of any other
remedies or means of redress to which Landlord may lawfully be entitled, and
Landlord may invoke any remedy allowed at law or in equity as if specific
remedies were not herein provided for.

            6.08 Certain Waivers; Waiver of Trial by Jury. (a) Tenant waives and
surrenders all right and privilege that Tenant might have under or by reason of
any present or future law to redeem the Premises or to have a continuance of
this Lease after Tenant is dispossessed or ejected therefrom by Landlord, by
process of law or under the terms of this Lease or after any termination of this
Lease. Tenant also waives the provisions of any law relating to notice and/or
delay in levy of execution in case of any eviction or dispossession for
nonpayment of rent, and the provisions of any successor or other law of like
import.

            (b) Landlord and Tenant each waive trial by jury in any action in
connection with this Lease.

            6.09 No Waiver. Failure by either party to declare any default
immediately upon its occurrence or delay in taking any action in connection with
such default shall not waive such default but such party shall have the right to
declare any such default at any time thereafter. Any amounts paid by Tenant to
Landlord may be applied by Landlord, in Landlord's discretion, to any items then
owing by Tenant to Landlord under this Lease. Receipt by Landlord of a partial
payment shall not be deemed to be an accord and satisfaction (notwithstanding
any endorsement or statement on any check or any letter accompanying any check
or payment) nor shall such receipt constitute a waiver by Landlord of Tenant's
obligation to make full payment. No act or thing done by Landlord or its agents
shall be deemed an acceptance of a surrender of the Premises, and no agreement
to accept such surrender shall be valid unless in writing and signed by Landlord
and by each Superior Lessor and Superior Mortgagee whose lease or mortgage
provides that any such surrender may not be accepted without its consent.

            6.10 Holding Over. If Tenant holds over without the consent of
Landlord after expiration or termination of this Lease, Tenant shall (a) pay as
holdover rental during the holdover tenancy an amount equal to (x) 150% for the
first month of the holdover tenancy, (y) 175% for the second month of the
holdover tenancy and (z) 200% for the third month and any additional month(s) of
the holdover tenancy of the greater of (i) the fair market rental value of the
Premises for such month (as reasonably determined by Landlord) or (ii) the Rent
which Tenant was obligated to pay for the month immediately preceding the end of
the Term; and (b) be liable to

                                     - 41 -

<PAGE>

Landlord for and indemnify Landlord against (i) any payment or rent concession
which Landlord may be required to make to any tenant obtained by Landlord for
all or any part of the Premises (a "New Tenant") by reason of the late delivery
of space to the New Tenant as a result of Tenant's holding over or in order to
induce such New Tenant not to terminate its lease by reason of the holding over
by Tenant, (ii) the loss of the benefit of the bargain if any New Tenant shall
terminate its lease by reason of the holding over by Tenant and (iii) any claim
for damages by any New Tenant. No holding over by Tenant after the Term shall
operate to extend the Term. Notwithstanding the foregoing, the acceptance of any
rent paid by Tenant pursuant to this Section 6.10 shall not preclude Landlord
from commencing and prosecuting a holdover or summary eviction proceeding.

            6.11 Attorneys' Fees. If Landlord places the enforcement of this
Lease or any part thereof, or the collection of any Rent due or to become due
hereunder, or recovery of the possession of the Premises, in the hands of an
attorney, or files suit upon the same, or in the event any bankruptcy,
insolvency or other similar proceeding is commenced involving Tenant, and
Landlord prevails in such enforcement action, Tenant shall, upon demand,
reimburse Landlord for Landlord's reasonable attorneys' fees and disbursements
and court costs.

            6.12 Nonliability and Indemnification. (a) Neither Landlord, any
Superior Lessor or any Superior Mortgagee, nor any partner, director, officer,
shareholder, principal, agent, servant or employee of Landlord, any Superior
Lessor or any Superior Mortgagee (whether disclosed or undisclosed), shall be
liable to Tenant for (i) any loss, injury or damage to Tenant or to any other
person, or to its or their property, irrespective of the cause of such injury,
damage or loss, nor shall the aforesaid parties be liable for any loss of or
damage to property of Tenant or of others entrusted to employees of Landlord;
provided, that, except to the extent of the release of liability and waiver of
subrogation provided in Section 7.03 hereof, the foregoing shall not be deemed
to relieve Landlord of any liability to the extent resulting from the negligence
or the willful act or failure to act of Landlord, its agents, servants or
employees in the operation or maintenance of the Premises or the Building, (ii)
any loss, injury or damage described in clause (i) above caused by other tenants
or persons in, upon or about the Building, or caused by operations in
construction of any private, public or quasi-public work, or (iii) even if
negligent, consequential damages arising out of any loss of use of the Premises
or any equipment, facilities or other Tenant's Property therein.

                  (b) Tenant shall indemnify and hold harmless Landlord, all
Superior Lessors and all Superior Mortgagees and each of their respective
members, partners, directors, officers, shareholders, principals, agents and
employees (each, an "Indemnified Party"), from and against any and all claims
arising from or in connection with (i) the conduct or management of the Premises
or of any business therein, or any work or thing done, or any condition created,
in or about the Premises, (ii) any act, omission or negligence of Tenant or any
person claiming through or under Tenant or any of their respective members,
partners, directors, officers, agents, employees or Contractors, (iii) any
accident, injury or damage occurring in, at or upon the Premises, (iv) any
default by Tenant in the performance of Tenant's obligations under this Lease
and (v) any brokerage commission or similar compensation claimed to be due by
reason of any proposed subletting or assignment by Tenant (irrespective of the
exercise by Landlord of any of the options in Section 5.02(b); together with all
costs, expenses and liabilities incurred in

                                     - 42 -

<PAGE>

connection with each such claim or action or proceeding brought thereon,
including, without limitation, all attorneys' fees and disbursements; provided,
that the foregoing indemnity shall not apply to the extent such claim results
from the negligence (other than negligence to which the release of liability and
waiver of subrogation provided in Section 7.03 below applies) or willful
misconduct of the Indemnified Party. If any action or proceeding is brought
against any Indemnified Party by reason of any such claim, Tenant, upon notice
from such Indemnified Party shall resist and defend such action or proceeding
(by counsel reasonably satisfactory to such Indemnified Party).

            6.13 Protest of Landlord Charges. Except as otherwise set forth in
Section 2.10 of this Lease, Tenant shall have sixty (60) days from receipt of a
bill or other request from Landlord for payment of any charge, other than the
Fixed Rent, payable by Tenant under this Lease within which to protest the
correctness of such charge. If Tenant fails to make such protest, which shall be
made in the manner herein set forth for the giving of notices, within the sixty
(60) day period aforementioned, the charge set forth in such bill or other
request shall be deemed to have been accepted by Tenant and shall no longer be
contestable by Tenant, time being of the essence.

                                    ARTICLE 7

                        Insurance; Casualty; Condemnation

            7.01 Compliance with Insurance Standards. (a) Tenant shall not
violate, or permit the violation of, any condition imposed by any insurance
policy then issued in respect of the Project and shall not do, or permit
anything to be done, or keep or permit anything to be kept in the Premises,
which would subject Landlord, any Superior Lessor or any Superior Mortgagee to
any liability or responsibility for personal injury or death or property damage,
or which would increase any insurance rate in respect of the Project over the
rate which would otherwise then be in effect or which would result in insurance
companies of good standing refusing to insure the Project in amounts reasonably
satisfactory to Landlord, or which would result in the cancellation of or the
assertion of any defense by the insurer in whole or in part to claims under, any
policy of insurance in respect of the Project.

                  (b) If, by reason of any failure of Tenant to comply with this
Lease, the premiums on Landlord's insurance on the Project shall be higher than
they otherwise would be, Tenant shall reimburse Landlord, on demand, for that
part of such premiums attributable to such failure on the part of Tenant. A
schedule or "make up" of rates for the Project or the Premises, as the case may
be, issued by the New York Fire Insurance Rating Organization or other similar
body making rates for insurance for the Project or the Premises, as the case may
be, shall be conclusive evidence of the facts therein stated and of the several
items and charges in the insurance rate then applicable to the Project or the
Premises, as the case may be.

            7.02 Tenant's Insurance. Tenant shall maintain at all times during
the Term (a) "all risk" property insurance covering all present and future
Tenant's Property, Fixtures and

                                     - 43 -

<PAGE>

Tenant's Improvements and Betterments to a limit of not less than the full
replacement cost thereof, and (b) commercial general liability insurance,
including a contractual liability endorsement, and personal injury liability
coverage, in respect of the Premises and the conduct or operation of business
therein, with Landlord and its managing agent, if any, and each Superior Lessor
and Superior Mortgagee whose name and address shall have been furnished to
Tenant, as additional insureds, with limits of not less than $5,000,000 combined
single limit for bodily injury and property damage liability in any one
occurrence and (c) boiler and machinery insurance, if there is a boiler,
supplementary air conditioner or pressure object or similar equipment in the
Premises, with Landlord and its managing agent, if any, and each Superior Lessor
and Superior Mortgagee whose name and address shall have been furnished to
Tenant, as additional insureds, with limits of not less than $5,000,000 combined
single limit and (d) when Alterations are in process, the insurance specified in
Section 4.02(f) hereof. The limits of such insurance shall not limit the
liability of Tenant. Tenant shall deliver to Landlord and any other additional
insureds, at least 10 days prior to the Possession Date, such fully paid-for
policies or certificates of insurance, in form reasonably satisfactory to
Landlord issued by the insurance company or its authorized agent. Tenant shall
procure and pay for renewals of such insurance from time to time before the
expiration thereof; and Tenant shall deliver to Landlord and any other
additional insureds such renewal policy or a certificate thereof at least 30
days before the expiration of any existing policy. All such policies shall be
issued by companies of recognized responsibility licensed to do business in New
York State and rated by Best's Insurance Reports or any successor publication of
comparable standing as A-/VIII or better or the then equivalent of such rating,
and all such policies shall contain a provision whereby the same cannot be
canceled, allowed to lapse or modified unless Landlord and any additional
insureds are given at least 30 days' prior written notice of such cancellation,
lapse or modification. The proceeds of policies providing "all risk" property
insurance of Tenant's Fixtures and Improvements and Betterments shall be payable
to Landlord, Tenant and each Superior Lessor and Superior Mortgagee as their
interests may appear. Tenant shall cooperate with Landlord in connection with
the collection of any insurance monies that may be due in the event of loss and
Tenant shall execute and deliver to Landlord such proofs of loss and other
instruments which may be required to recover any such insurance monies. Landlord
may from time to time require that the amount of the insurance to be maintained
by Tenant under this Section 7.02 be increased, so that the amount thereof
adequately protects Landlord's interest.

            7.03 Subrogation Waiver. Landlord and Tenant shall each include in
each of its insurance policies (insuring the Building in case of Landlord, and
insuring Tenant's Property, Fixtures and Improvements and Betterments in the
case of Tenant, against loss, damage or destruction by fire or other casualty) a
waiver of the insurer's right of subrogation against the other party during the
Term or, if such waiver should be unobtainable or unenforceable, (a) an express
agreement that such policy shall not be invalidated if the assured waives the
right of recovery against any party responsible for a casualty covered by the
policy before the casualty or (b) any other form of permission for the release
of the other party. Each party hereby releases the other party with respect to
any claim (including a claim for negligence) which it might otherwise have
against the other party for loss, damage or destruction with respect to its
property occurring during the Term to the extent to which it is, or is required
to be, insured under a policy or policies containing a waiver of subrogation or
permission to release liability. Nothing contained in this

                                     - 44 -

<PAGE>

Section 7.03 shall be deemed to relieve either party of any duty imposed
elsewhere in this Lease to repair, restore or rebuild or to nullify any
abatement of rents provided for elsewhere in this Lease.

            7.04 Condemnation. (a) If there shall be a total taking of the
Building in condemnation proceedings or by any right of eminent domain, this
Lease and the term and estate hereby granted shall terminate as of the date of
taking of possession by the condemning authority and all Rent shall be prorated
and paid as of such termination date. If there shall be a taking of any material
(in Landlord's reasonable judgment) portion of the Land or the Building (whether
or not the Premises are affected by such taking), then Landlord may terminate
this Lease and the term and estate granted hereby by giving notice to Tenant
within 60 days after the date of taking of possession by the condemning
authority. If there shall be a taking of the Premises of such scope (but in no
event less than 25% thereof) that the untaken part of the Premises would in
Tenant's reasonable judgment be uneconomic to operate, then Tenant may terminate
this Lease and the term and estate granted hereby by giving notice to Landlord
within 60 days after the date of taking of possession by the condemning
authority. If either Landlord or Tenant shall give a termination notice as
aforesaid, then this Lease and the term and estate granted hereby shall
terminate as of the date of such notice and all Rent shall be prorated and paid
as of such termination date. In the event of a taking of the Premises which does
not result in the termination of this Lease (i) the term and estate hereby
granted with respect to the taken part of the Premises shall terminate as of the
date of taking of possession by the condemning authority and all Rent shall be
appropriately abated for the period from such date to the Expiration Date and
(ii) Landlord shall with reasonable diligence restore the remaining portion of
the Premises (exclusive of Tenant's Property) as nearly as practicable to its
condition prior to such taking.

                  (b) In the event of any taking of all or a part of the
Building, Landlord shall be entitled to receive the entire award in the
condemnation proceeding, including, without limitation, any award made for the
value of the estate vested by this Lease in Tenant or any value attributable to
the unexpired portion of the Term, and Tenant hereby assigns to Landlord any and
all right, title and interest of Tenant now or hereafter arising in or to any
such award or any part thereof, and Tenant shall be entitled to receive no part
of such award; provided, that nothing shall preclude Tenant from intervening in
any such condemnation proceeding to claim or receive from the condemning
authority any compensation to which Tenant may otherwise lawfully be entitled in
such case in respect of Tenant's Property or moving expenses, provided the same
does not include any value of the estate vested by this Lease in Tenant or of
the unexpired portion of the Term and does not reduce the amount available to
Landlord or materially delay the payment thereof.

                  (c) If all or any part of the Premises shall be taken for a
limited period, Tenant shall be entitled, except as hereinafter set forth, to
that portion of the award for such taking which represents compensation for the
use and occupancy of the Premises, for the taking of Tenant's Property and for
moving expenses, and Landlord shall be entitled to that portion which represents
reimbursement for the cost of restoration of the Premises. This Lease shall
remain unaffected by such taking and Tenant shall continue responsible for all
of its obligations under this Lease to the extent such obligations are not
affected by such taking and shall continue to pay in full all Rent when due. If
the period of temporary use or occupancy shall extend beyond

                                     - 45 -

<PAGE>

the Expiration Date, that part of the award which represents compensation for
the use and occupancy of the Premises shall be apportioned between Landlord and
Tenant as of the Expiration Date. Any award for temporary use and occupancy for
a period beyond the date to which the Rent has been paid shall be paid to, held
and applied by Landlord as a trust fund for payment of the Rent thereafter
becoming due.

                  (d) In the event of any taking which does not result in
termination of this Lease, (i) Landlord, whether or not any award shall be
sufficient therefor, shall proceed with reasonable diligence to repair the
remaining parts of the Building and the Premises (other than those parts of the
Premises which constitute Tenant's Property) to substantially their former
condition to the extent that the same may be feasible (subject to reasonable
changes which Landlord deems desirable) and so as to constitute a complete and
rentable Building and Premises and (ii) Tenant, whether or not any award shall
be sufficient therefor, shall proceed with reasonable diligence to repair the
remaining parts of the Premises which constitute Tenant's Property, to
substantially their former condition to the extent that the same may be
feasible, subject to reasonable changes which shall be deemed Alterations.

            7.05 Casualty. (a) If the Building or the Premises shall be
partially or totally damaged or destroyed by fire or other casualty (each, a
"Casualty") and if this Lease is not terminated as provided below, then (i)
Landlord shall repair and restore the Building and the Premises (excluding
Tenant's Improvements and Betterments, Fixtures and Tenant's Property) with
reasonable dispatch (but Landlord shall not be required to perform the same on
an overtime or premium pay basis) after notice to Landlord of the Casualty and
the collection of the insurance proceeds attributable to such Casualty and (ii)
Tenant shall repair and restore in accordance with Section 4.02 all Tenant's
Property, Fixtures and Improvements and Betterments with reasonable dispatch
after the Casualty.

                  (b) If all or part of the Premises shall be rendered
untenantable by reason of a Casualty, the Fixed Rent and the Additional Charges
under Sections 2.04 and 2.05 shall be abated in the proportion that the
untenantable area of the Premises bears to the total area of the Premises, for
the period from the date of the Casualty to the earlier of (i) the date the
Premises is made tenantable (provided, that if the Premises would have been
tenantable at an earlier date but for Tenant having failed to cooperate with
Landlord in effecting repairs or restoration or collecting insurance proceeds
(including, without limitation, by reason of Tenant failing to pay to Landlord
the amounts set forth in clauses (A) and (B) of Section 7.05(a)), then the
Premises shall be deemed to have been made tenantable on such earlier date and
the abatement shall cease) or (ii) the date Tenant or any subtenant reoccupies a
portion of the Premises (in which case the Fixed Rent and the Additional Charges
allocable to such reoccupied portion shall be payable by Tenant from the date of
such occupancy). Landlord's determination of the date the Premises is tenantable
shall be controlling unless Tenant disputes same by notice to Landlord within 10
days after such determination by Landlord, and pending resolution of such
dispute, Tenant shall pay Rent in accordance with Landlord's determination.
Notwithstanding the foregoing, (x) if by reason of any act or omission by
Tenant, any subtenant or any of their respective partners, directors, officers,
servants, employees, agents or Contractors, Landlord, any Superior Lessor or any
Superior Mortgagee shall be unable to collect all of the insurance proceeds
(including, without limitation, rent insurance proceeds) applicable to the
Casualty, or,

                                     - 46 -

<PAGE>

(y) if Tenant demolishes or otherwise alters the portion of the Premises
affected by any Casualty (other than as may be required by Laws, emergency
conditions or as part of Tenant's efforts to prevent further damage) without
Landlord's consent, then, without prejudice to any other remedies which may be
available against Tenant, there shall be no abatement of Rent. Nothing contained
in this Section 7.05 shall relieve Tenant from any liability that may exist as a
result of any Casualty.

                  (c) If by reason of a Casualty (i) the Building shall be
totally damaged or destroyed, (ii) the Building shall be so damaged or destroyed
(whether or not the Premises are damaged or destroyed) that repair or
restoration shall require more than 270 days or the expenditure of more than 20%
percent of the full insurable value of the Building (which, for purposes of this
Section 7.05(c), shall mean replacement cost less the cost of footings,
foundations and other structures below the street and first floors of the
Building) immediately prior to the Casualty or (iii) more than 30% of the
Premises shall be damaged or destroyed (as estimated in any such case by a
reputable contractor, architect or engineer designated by Landlord), then in any
such case Landlord may terminate this Lease by notice given to Tenant within 180
days after the Casualty.

                  (d) If (i) by reason of a Casualty the Building shall be so
damaged or destroyed that the Landlord's independent architect estimates that
repair or restoration shall require more than 270 days from the date of such
determination or (ii) if the Premises shall be rendered untenantable by reason
of a Casualty during the last 18 months of the Term of this Lease, then Tenant
may terminate this Lease by written notice given to Landlord within 60 days
after the Casualty.

                  (e) Landlord shall not carry any insurance on Tenant's
Property, Fixtures or on Tenant's Improvements and Betterments and shall not be
obligated to repair or replace Tenant's Property, Fixtures or Improvements and
Betterments. Tenant shall look solely to its insurance for recovery of any
damage to or loss of Tenant's Property, Fixtures or Tenant's Improvements and
Betterments. Tenant shall notify Landlord promptly of any Casualty in the
Premises.

                  (f) This Section 7.05 shall be deemed an express agreement
governing any damage or destruction of the Premises by fire or other casualty,
and Section 227 of the New York Real Property Law providing for such a
contingency in the absence of an express agreement, and any other law of like
import now or hereafter in force, shall have no application.

                                    ARTICLE 8

                            Miscellaneous Provisions

            8.01 Notice. All notices, demands, consents, approvals, advices,
waivers or other communications which may or are required to be given by either
party to the other under this Lease shall be in writing and shall be deemed to
have been given one Business Day after

                                     - 47 -

<PAGE>

deposit in the United States mail, certified or registered, postage prepaid,
return receipt requested, and addressed to the party to be notified at the
address for such party specified in the first paragraph of this Lease or to such
other place as the party to be notified may from time to time designate by at
least 5 days' notice to the notifying party (and, in the case of each notice to
Landlord, to (a) Landlord's address specified in the first paragraph of this
Lease, Attention: Mr. Morton F. Silver with a copy to (b) Fried, Frank, Harris,
Shriver & Jacobson, One New York Plaza, New York, New York 10004, Attention:
Jonathan L. Mechanic, Esq. and, in the case of each notice to Tenant, with a
copy to (x) McLaughlin and Stern, LLP, 260 Madison Avenue, 18th Floor, New York,
New York 10016, Attention: Henry Feuerstein. Notices from Landlord may be given
by Landlord's managing agent, if any, or by Landlord's attorney.

            8.02 Building Rules. Tenant shall comply with, and Tenant shall
cause its licensees, employees, Contractors, agents and invitees to comply with,
the rules of the Building set forth in the Rules and Regulations, as the same
may be reasonably modified or supplemented by Landlord from time to time for the
safety, care and cleanliness of the Premises and the Building and for
preservation of good order therein. Landlord shall not be obligated to enforce
the rules of the Building against Tenant or any other tenant of the Building or
any other party, and Landlord shall have no liability to Tenant by reason of the
violation by any tenant or other party of the rules of the Building; provided,
that Landlord shall not promulgate or enforce the rules of the Building in a
manner which discriminates against Tenant. If any rule of the Building shall
conflict with any provision of this Lease, such provision of this Lease shall
govern.

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

            8.04 Certain Definitions. (a) "Landlord" means only the owner, at
the time in question, of the Building or that portion of the Building of which
the Premises are a part, or of a lease of the Building or that portion of the
Building of which the Premises are a part, so that in the event of any transfer
or transfers of title to the Building or of Landlord's interest in a lease of
the Building or such portion of the Building, the transferor shall be and hereby
is relieved and freed of all obligations of Landlord under this Lease accruing
after such transfer, and it shall be deemed, without further agreement, that
such transferee has assumed all obligations of Landlord during the period it is
the holder of Landlord's interest under this Lease.

                  (b) "Landlord shall have no liability to Tenant" or words of
similar import mean that Tenant is not entitled to terminate this Lease, or to
claim actual or constructive eviction, partial, or total, or to receive any
abatement or diminution of Rent, or to be relieved in any manner or any of its
other obligations under this Lease, or to be compensated for loss or injury
suffered or to enforce any other right or kind of liability whatsoever against
Landlord under or with respect to this Lease or with respect to Tenant's use or
occupancy of the Premises.

            8.05 Quiet Enjoyment. Tenant shall and may peaceably and quietly
have, hold and enjoy the Premises, subject to the other terms of this Lease and
to Superior Leases and

                                     - 48 -

<PAGE>

Superior Mortgages, provided that Tenant pays the Fixed Rent and Additional
Charges to be paid by Tenant and performs all of Tenant's covenants and
agreements contained in this Lease.

            8.06 Limitation of Landlord's Liability. (a) Tenant shall look
solely to Landlord's interest in the Project for the recovery of any judgment
against Landlord, and no other property or assets of Landlord or Landlord's
members, partners, officers, directors, shareholders or principals, direct or
indirect, disclosed or undisclosed, shall be subject to levy, execution
attachment or other enforcement procedure for the satisfaction of any judgment
or Tenant's remedies under or with respect to this Lease, the relationship of
Landlord and Tenant hereunder, or Tenant's use and occupancy of the Premises, or
any other liability of Landlord to Tenant.

            (b) In the event of a transfer of title to the land and Building of
which the Premises is a part, or in the event of a lease of the Building of
which the Premises is a part, or of the land and Building, upon notification to
Tenant of such transfer or lease, the said transferor landlord named herein
shall be and hereby is entirely freed and relieved of all future covenants,
obligations and liabilities of Landlord hereunder, and it shall be deemed and
construed without further agreement between the parties or their successors in
interest, or between the parties and the transferee of title to or lessee of
said land and Building, that the transferee or lessee has assumed and agreed to
carry out all of the covenants and obligations of Landlord hereunder.

            8.07 Counterclaims. If Landlord commences any summary proceeding or
action for nonpayment of Rent or to recover possession of the Premises, Tenant
shall not interpose any counterclaim of any nature or description in any such
proceeding or action, unless Tenant's failure to interpose such counterclaim in
such proceeding or action would result in the waiver of Tenant's right to bring
such claim in a separate proceeding under applicable law.

            8.08 Survival. All obligations and liabilities of Landlord or Tenant
to the other which accrued before the expiration or other termination of this
Lease and all such obligations and liabilities which by their nature or under
the circumstances can only be, or by the provisions of this Lease may be,
performed after such expiration or other termination, shall survive the
expiration or other termination of this Lease. Without limiting the generality
of the foregoing, the rights and obligations of the parties with respect to any
indemnity under this Lease, and with respect to Tax Payments and any other
amounts payable under this Lease, shall survive the expiration or other
termination of this Lease.

            8.09 Certain Remedies. If Tenant requests Landlord's consent and
Landlord fails or refuses to give such consent, Tenant shall not be entitled to
any damages for any withholding by Landlord of its consent, it being intended
that Tenant's sole remedy shall be an action for specific performance or
injunction, and that such remedy shall be available only in those cases where
this Lease provides that Landlord shall not unreasonably withhold its consent.
No dispute relating to this Lease or the relationship of Landlord and Tenant
under this Lease shall be resolved by arbitration unless this Lease expressly
provides for such dispute to be resolved by arbitration.

applicable, Tenant shall remove any such signage from the Temporary Space and
shall repair and restore any area of the Temporary Space impacted by such
signage to the condition of such area as of the date of this Lease. If Tenant

                                    ARTICLE 9

                                  Renewal Right

            9.01 Renewal Right. (a) Provided that on the date Tenant exercises
the Renewal Option and at the commencement of the Renewal Term (i) this Lease
shall not have been terminated, (ii) Tenant shall not be in monetary default
beyond any applicable notice and grace period under this Lease and (iii) Tenant
named herein (i.e., ACTV, Inc.), an Affiliate or a permitted assignee of Tenant
shall occupy the entire Premises, Tenant shall have the option (the "Renewal
Option") to extend the term of this Lease for an additional five (5) year period
(the "Renewal Term"), to commence at the expiration of the initial Term.

            (b) The Renewal Option shall be exercised with respect to the entire
Premises only and shall be exercisable by Tenant giving notice to Landlord (the
"Renewal Notice") at least

                                     - 51 -

<PAGE>

18 months before the last day of the initial Term. Time is of the essence with
respect to the giving of the Renewal Notice.

            9.02 Renewal Rent and Other Terms. (a) The Renewal Term shall be
upon all of the terms and conditions set forth in this Lease, except that (i)
the Fixed Rent shall be as determined pursuant to the further provisions of this
Section 9.02; (ii) Tenant shall accept the Premises in its "as is" condition at
the commencement of the Renewal Term, and Landlord shall not be required to
perform Landlord's Initial Work or any other work, pay the Landlord's
Contribution or any other amount or render any services to make the Premises
ready for Tenant's use and occupancy or provide any abatement of Fixed Rent or
Additional Charges, in each case with respect to the Renewal Term; (iii) Tenant
shall have no option to renew this Lease beyond the expiration of the Renewal
Term; and (iv) the Base Tax Amount shall be the Taxes for the Tax Year ending
immediately before the commencement of the Renewal Term.

            (b) The annual Fixed Rent for the Premises for the Renewal Term
shall be the greater of (i) the Fair Market Rent or (ii) an amount (the "Annual
Rent") equal to the aggregate of (A) the Fixed Rent payable by Tenant for the 12
month period ending on the last day of the initial Term and (B) the Tax Payment
payable with respect to the Tax Year ending immediately before the commencement
of the Renewal Term (the greater of Fair Market Rent and Annual Rent is called
the "Rental Value"). "Fair Market Rent" means the fixed annual rent that a
willing lessee would pay and a willing lessor would accept for the Premises
during the Renewal Term, taking into account all relevant factors, including,
without limitation, market rents then being charged for comparable space in
other similar office buildings in the same area and all of the following which
shall be assumed: (X) the Landlord and prospective tenant are typically
motivated; (Y) the Landlord and prospective tenant are well informed and well
advised and each is acting in what it considers its own best interest; and (Z)
in the event the Premises have been destroyed or damaged by fire or other
casualty, they have been fully restored. The following shall have been presumed
to have been done: (A) a reasonable time under then-existing market conditions
has been allowed for exposure of the Premises on the open market; (B) the
prospective tenant has been given the benefit of customary rent concessions or
free rent periods than pertaining in the community for comparable space of a
similar size; (C) the Premises have been newly renovated to the prospective
tenant's specifications and are acceptable to the prospective tenant "as is;"
(D) the Premises have been let with vacant possession and subject to the
provisions of this Lease for a 5-year term; (E) the computation of the number of
rentable square feet contained in the Premises has been based on the measurement
standard then prevalent in the market for comparable space; and (F) a full
brokerage commission shall have been paid by Landlord on then market terms.
Notwithstanding that the factors enumerated above are to be assumed or presumed
to have already been given in the determination of Fair Market Rent, Landlord
shall not be obliged to give Tenant any of the foregoing benefits.

            (c) If Tenant timely exercises the Renewal Option, Landlord shall
notify Tenant (the "Rent Notice") at least 120 days before the last day of the
initial Term of Landlord's determination of the Fair Market Rent ("Landlord's
Determination"). If Landlord's Determination exceeds the Annual Rent, then
Tenant shall notify Landlord ("Tenant's Notice"), within 20 days after Tenant's
receipt of the Rent Notice, whether Tenant accepts or disputes Landlord's
Determination, and if Tenant disputes Landlord's Determination, Tenant's Notice
shall

                                     - 52 -

<PAGE>

set forth Tenant's determination of the Fair Market Rent (which shall not be
less than the Annual Rent). If Tenant fails to give Tenant's Notice within such
20 day period, Tenant shall be deemed to have accepted Landlord's Determination.

            (d) If Tenant timely disputes Landlord's Determination and Landlord
and Tenant fail to agree as to the Fair Market Rent within 20 days after the
giving of Tenant's Notice, then the Fair Market Rent shall be determined as
follows: Such dispute shall be resolved by arbitration conducted in accordance
with the Real Estate Valuation Arbitration Rules (Expedited Procedures) of the
AAA, except that the provisions of this Section 9.02(d) shall supersede any
conflicting or inconsistent provisions of said rules. The party requesting
arbitration shall do so by giving notice to that effect to the other party,
specifying in said notice the nature of the dispute, and that said dispute shall
be determined in the City of New York, by a panel of 3 arbitrators in accordance
with this Section 9.02(d). Landlord and Tenant shall each appoint their own
arbitrator within 7 days after the giving of notice by either party. If either
Landlord or Tenant shall fail timely to appoint an arbitrator, the appointed
arbitrator shall select the second arbitrator, who shall be impartial, within 7
days after such party's failure to appoint. Such two arbitrators shall have 7
days to appoint a third arbitrator who shall be impartial. If such arbitrators
fail to do so, then either Landlord or Tenant may request the AAA to appoint an
arbitrator who shall be impartial within 14 days of such request and both
parties shall be bound by any appointment so made within such 14-day period. If
no such third arbitrator shall have been appointed within such 14 days, either
Landlord or Tenant may apply to any court having jurisdiction to make such
appointment. The third arbitrator only shall subscribe and swear to an oath
fairly and impartially to determine such dispute. Within 14 days after the third
arbitrator has been appointed, each arbitrator shall render its determination of
the Fair Market Rent in writing and shall submit same to each of the other
arbitrators, and to Landlord and Tenant. If at least two of the three
arbitrators shall concur in their determination of the Fair Market Rent, their
determination shall be final and binding upon the parties. If the arbitrators
fail to concur, then the Fair Market Rent shall be equal to 50% of the sum of
the two determinations by the arbitrators closest in amount, and such amount
shall be final and binding upon the parties. The fees and expenses of any
arbitration pursuant to this Section 9.02(d) shall be borne by the parties
equally, but each party shall bear the expense of its own arbitrator, attorneys
and experts and the additional expenses of presenting its own proof The
arbitrators shall not have the power to add to, modify or change any of the
provisions of this Lease. Each arbitrator shall have at least 10 years'
experience in leasing and valuation of properties which are similar in character
to the Building. After a determination has been made of the Fair Market Rent,
the parties shall execute and deliver an instrument setting forth the Fair
Market Rent, but the failure to so execute and deliver any such instrument shall
not affect the determination of Fair Market Rent.

            (e) If Tenant disputes Landlord's Determination and if the final
determination of Fair Market Rent shall not be made on or before the first day
of the Renewal Term, then, pending such final determination, Tenant shall pay,
as Fixed Rent for the Renewal Term, an amount equal to the last month's Fixed
Rent payable under this Lease plus ten (10%) percent. If, based upon the final
determination of the Fair Market Rent, the Fixed Rent payments made by Tenant
for such portion of the Renewal Term were (i) less than the Rental Value payable
for the Renewal Term, Tenant shall pay to Landlord the amount of such deficiency
within 10 days after demand therefor or (ii) greater than the Rental Value
payable for the Renewal Term, Landlord

                                     - 53 -

<PAGE>

shall credit the amount of such excess against future installments of Fixed Rent
and/or Additional Charges payable by Tenant.

                                 Expansion Space

Expansion Option shall be exercisable by Tenant giving Landlord notice thereof
(the "Expansion Notice") on or before April 1, 2000 (time being of the essence).
If Tenant timely gives the Expansion Notice, on the ES Inclusion Date, the
Expansion Space shall become part of the Premises, upon all of the terms and
conditions set forth in this Lease, except that:

            (a) Fixed rent for the Expansion Space shall be (i) for the period
commencing on the ES Inclusion Date and ending on the day immediately preceding
the 5th anniversary of the ES Inclusion Date Three Hundred Ninety Thousand Nine
Hundred Forty-Four and 00/100 ($390,944.00) Dollars, payable in equal monthly

anniversary of the ES Inclusion Date and ending on the day immediately preceding
the 10th anniversary of the ES Inclusion Date, Four Hundred Twenty-Seven
Thousand Five Hundred Ninety-Five and 00/100 ($427,595.00) Dollars per annum,
payable in equal monthly installments of Thirty-Five Thousand Six Hundred

Expiration Date, Four Hundred Sixty-Four Thousand Two Hundred Forty-Six and
00/100 ($464,246.00) Dollars (an annual rate of $38.00 per rentable square foot
contained in the Expansion Space). Fixed Rent shall be payable by Tenant in
equal monthly installments in advance on the ES Inclusion Date and on the first
day of each calendar month thereafter. From and after the ES Inclusion Date, the
term "Fixed Rent" (as defined herein) shall include the fixed rent for the
Expansion Space;

            (b) From and after Tenant's exercise of the Expansion Option until
August 1, 2000 (the "ES Election Period"), and provided that Tenant delivers to
Landlord written evidence reasonably satisfactory to Landlord that Tenant's
Expansion Space Alterations (defined below) will cost a minimum of Fifteen ($15)
Dollars per rentable square foot, Tenant shall have the right to elect to forego
receipt of Landlord's Expansion Space Work Contribution pursuant to Section 10.0
1(e) hereunder and, in lieu thereof, receive a reduction in fixed rent for the
Expansion Space

                                     - 54 -

<PAGE>

of $1.81 per year per rentable square feet contained in the Expansion Space
(i.e., $22,112.77 per year with respect to the Expansion Space). Tenant shall
give Landlord such written notice on or prior to the expiration of the ES
Election Period. Time shall be of the essence with respect to the giving of such
notice;

            (c) Each of the provisions of Section 2.04 shall apply to the
Expansion Space except (i) the term "Building A" in Section 2.04(b)(i) shall be
replaced by "Building B" for the purpose of calculating Taxes with respect to
the Expansion Space and (ii) Tenant's Tax Share with respect to the Expansion
Space shall be 8.4999% ("Expansion Space Tax Share") and any reference with
respect to Tenant's Tax Share shall be deemed to refer to the Expansion Space
Tax Share when calculating the Taxes for the Expansion Space. The parties hereto
agree that the rentable square foot area of the Expansion Space shall be deemed
to be 12,217 rentable square feet and the rentable square foot area of Building
B shall be deemed to be 143,731 rentable square feet. The Expansion Space Tax
Share has been determined by dividing the rentable square foot area of the
Expansion Space by the rentable square foot area of Building B,

            (d) The Multiplication Factor shall be increased by 12,217 rentable
square feet;

            (e) Landlord agrees to contribute Fifteen ($15) Dollars per rentable
square foot of the Expansion Space for a total of $183,255 ("Expansion Space
Work Contribution"), toward the cost of the Tenant's Initial Improvements with
respect to the Expansion Space ("Expansion Space Alterations"). Landlord shall
pay the Expansion Space Work Contribution to Tenant's Contractor(s) over the
duration of the construction, no more frequently than monthly, on receipt of a
notice from Tenant of the names of the Contractor(s) who performed work or
supplied materials with respect to Tenant's Expansion Space Alterations,
together with an Application and Certificate for Payment on AIA Document G702
and G703, or similar form, duly executed by the Contractor(s) to be paid, and
Tenant's architect, who shall certify to Landlord (i) that the work performed
and materials delivered under said application generally conform to Tenant's
Plans, (ii) that the amount of such payment request approved by the architect is
justified by the work, (iii) the percentage of Tenant's Expansion Space
Alterations completed by that date, (iv) that no less than 85% of the cost of
work to be paid from the Expansion Space Work Contribution (i.e., $155,766.75)
has been incurred in respect of hard costs and (v) that in said architect's
opinion adequate funds remain to complete Tenant's Expansion Space Alterations.
Landlord may retain ten (10%) percent of each requested amount until ten (10)
days after (w) substantial completion of Tenant's Expansion Space Alterations,
(x) delivery to Landlord of waivers of mechanic's/materialmen's liens from all
of Tenant's Contractor(s) for amounts paid to date, and statements from the
Contractor(s) stating the balance owed, (y) receipt of invoices, requisitions,
canceled checks or other documentary evidence showing payment of the cost of
Tenant's Expansion Space Alterations, and (z) receipt of two (2) sets of
as-built drawings, or drawings marked "Final", of the improved Expansion Space.
For each request for payment made by Tenant, the amount of Expansion Space Work
Contribution to be paid to Tenant's Contractor(s) shall be determined by
multiplying the amount due to Tenant's Contractors by the Pro Rata Share. "Pro
Rata Share" shall mean the ratio of the Expansion Space Work Contribution to the
total estimated cost of Tenant's Expansion Space Alterations. Tenant shall
comply with all provisions of Section 4.01 in performing Tenant's Expansion
Space Alterations;

                                     - 55 -

<PAGE>

            (f) (i) In connection with the delivery of the Expansion Notice by
Tenant to Landlord, Tenant shall, simultaneously, deliver to Landlord, as
security for the performance of Tenant's obligations under this Lease, either
(a) the additional sum of $871,198.00, in certified or official bank check (the
"Expansion Space Security Deposit"), or (b) an unconditional, irrevocable letter
of credit in the amount of $871,198.00 in a form and issued by a bank reasonably
satisfactory to Landlord (the "Expansion Space Letter of Credit"). The Expansion
Space Letter of Credit shall provide that it is assignable by Landlord without
charge and shall either (x) expire on the LC Date (as defined herein) or (y) be
automatically self-renewing until the LC Date. If the Expansion Space Letter of
Credit is not renewed at least 30 days prior to the expiration thereof or if
Tenant holds over in the Premises without the consent of Landlord after the
expiration or termination of this Lease, Landlord may draw upon the Expansion
Space Letter of Credit and hold the proceeds thereof as security for the
performance of Tenant's obligations under this Lease. Landlord may draw on the
Expansion Space Security Deposit or Expansion Space Letter of Credit (or the
proceeds thereof) solely to remedy defaults by Tenant, which are beyond any
applicable notice and grace period, in the payment or performance of any of
Tenant's obligations under this Lease. If Landlord shall have so drawn upon the
Expansion Space Security Deposit or the Expansion Space Letter of Credit (or the
proceeds thereof), Tenant shall upon demand deposit with Landlord a sum equal to
the amount so drawn by Landlord. Landlord hereby agrees that a letter of credit
issued (i) in the form set forth in Exhibit I attached hereto and made a part
hereof and (ii) by Amalgamated Bank shall be deemed to be reasonably
satisfactory to Landlord. If Tenant delivers the Expansion Space Security
Deposit to Landlord in cash, then such Expansion Space Security Deposit shall be
kept in an interest-bearing account until applied in accordance with the terms
of this Lease (it being understood that Landlord shall not be liable for failure
to obtain any specific level of interest). Landlord shall pay such interest to
Tenant, less a one (1%) percent administrative fee, no more frequently than
annually, upon request of Tenant.

                  (ii) In the event that Tenant shall have, prior to the
expiration of the ES Election Period, elected to forego receipt of the Expansion
Space Work Contribution pursuant to Section 10.01(b) above, the amount of the
Expansion Space Security Deposit required hereunder shall be reduced by one
hundred eighty-three thousand two hundred fifty-five and 00/100 ($183,255.00)
dollars.

                  (iii) If, at any time, Tenant (1) completes a secondary public
offering of the Minimum Equity Amount or (2) otherwise receives an equity
infusion of the Minimum Equity Amount, which Minimum Equity Amount, by the terms
of the documents governing the same, can be used by Tenant as working capital,
then the Expansion Space Security Deposit required hereunder shall be reduced to
four hundred eighty-four thousand and 00/100 ($484,000.00) dollars;

                  (iv) If, prior to the expiration of the ES Election Period,
Tenant has elected to forego receipt of the Expansion Space Work Contribution
pursuant to Section 10.08(b) above, and if Tenant meets the requirements of
Section 10.08(f)(iii) above, then the Security Deposit shall be reduced to three
hundred nine thousand eight hundred seventy-two and 00/100 ($309,872.00) dollars
(the "ES Minimum Security Amount").

<PAGE>

                  (v) If, from and after the ES Inclusion Date, (1) there is not
a monetary default beyond any applicable notice and grace period under this
Lease and (2) Tenant delivers to Landlord evidence that it has a NOI of at least
four million ($4,000,000.00) dollars and that the Tenant has maintained a NAV of
at least twenty million ($20,000,000.00) dollars during the preceding
twenty-four (24) month period, then the Expansion Space Security Deposit shall
be reduced to three hundred nine thousand eight hundred seventy-two and 00/100
($309,872.00) dollars;

                  (vi) If the Expansion Space Security Deposit has not otherwise
been reduced to the ES Minimum Security Amount, then:

                        (a) if, during the first five (5) years of the Term,
there have not occurred more than three (3) monetary defaults beyond any
applicable notice and grace period under this Lease, then upon the sixth (6th)
anniversary of the ES Inclusion Date, the Security Deposit shall be reduced by
two hundred forty-seven thousand eight hundred ninety-seven and 00/100
($247,897.00) dollars; and

                        (b) if during the first ten (10) years of the Term,
there have not occurred more than six (6) monetary defaults beyond any
applicable notice and grace period, then upon the eleventh (11th) anniversary of
the ES Inclusion Date, the Security Deposit shall be reduced by two hundred
forty-seven thousand eight hundred ninety-seven and 00/100 ($247,897.00)
dollars;

                  (vii) If the Security Deposit is reduced pursuant to Section
1.08(a)(v)(D)(1) or (2) above, and after the date of such reduction there occurs
more than three (3) monetary defaults, beyond any applicable notice and grace
period, within any five (5) year period, the Security Deposit required shall be
increased to the amount of such Security Deposit immediately prior to such
reduction and Tenant shall be required to deliver to Landlord as further
security for the performance of Tenant's obligations under this Lease, within
ten (10) days notice from Landlord and in accordance with the provisions of
Section 1.08(a)(v)(A) above, two hundred forty-seven thousand eight hundred
ninety-seven ($247,897.00) dollars;

                  (viii) Notwithstanding anything to the contrary contained in
this Section 1.08(a)(vi), in no event shall the Expansion Space Security Deposit
be reduced to less than the ES Minimum Security Amount;

                  (ix) In the event that Tenant is entitled to a reduction in
the amount of the Expansion Space Security Deposit under Sections 1.08(a)(v)(B),
(C), or (D) above, Landlord shall (1) if the Expansion Space Security Deposit
was paid in cash, return the amount of such reduction to Tenant by check or (2)
if the Expansion Space Security Deposit was given in the form of a letter of
credit, exchange the existing Expansion Space Letter of Credit for a letter of
credit in the amount of the reduced Expansion Space Security Deposit. If, within
thirty (30) days after receiving notice from Tenant that Tenant is entitled to a
reduction in the Expansion Space Security Deposit, unless Landlord is disputing
the same, Landlord does not return the amount of the reduction to Tenant or, if
applicable, cooperate with Tenant in obtaining a new letter of credit for the
reduced amount of the Expansion Space Security Deposit, then Tenant shall be
entitled to

                                      -57-

<PAGE>

interest, at the Interest Rate, on the amount of the reduction of the Expansion
Space Security Deposit. "Interest Rate" means the lesser of (i) the prime rate
from time to time announced by Citibank, N.A. (or, if Citibank, N.A. shall not
exist, such other bank in New York, New York, as shall be designated by Landlord
in a notice to Tenant) to be in effect at its principal office in New York, New
York plus 2% or (ii) the maximum rate permitted by law; and

            10.02 ES Inclusion Date. (a) The "ES Inclusion Date" shall be the
Possession Date and, if the Possession Date shall not have occurred as a result
of the termination of this Lease with respect to the Original Premises in
accordance with Section 1.06(e) herein, then the ES Inclusion Date shall be the
date of the Termination Notice.

            (b) Promptly after the occurrence of the ES Inclusion Date, Landlord
and Tenant shall confirm the occurrence thereof and the inclusion of the
Expansion Space in the Premises by executing an instrument reasonably
satisfactory to Landlord and Tenant; provided, that failure by Landlord or
Tenant to execute such instrument shall not affect the inclusion of the
Expansion Space in the Premises in accordance with this Article 10.

            10.03 Services. If Tenant exercises the Expansion Option set forth
in this Article 10, Landlord shall provide the Expansion Space with the services
described in Section 3.01(b) herein throughout the Term of this Lease.

            10.04 Alternate Space. Notwithstanding anything to the contrary
contained herein, if Tenant gives to Landlord an Expansion Notice on or before
April 1, 2000 (time being of the essence), Landlord may notify Tenant within ten
(10) days of receiving Tenant's Expansion Notice that Landlord, at Landlord's
cost and expense, intends to move Tenant to alternate space, of at least an
equal number of rentable square feet as the First Temporary Space, in the
Building (the "Alternate Space"); provided, that Landlord has signed a lease for
two or more floors, one of which is the First Temporary Space. If, at the time
the Expansion Notice is given, Landlord is actively negotiating a lease for two
or more floors which lease shall encompass the First Temporary Space, Landlord
shall provide notice to Tenant that Landlord is actively negotiating such a
lease. Landlord shall within three (3) months from the date of the Expansion
Notice notify Tenant that Landlord intends to move Tenant to Alternate Space. If
Landlord so notifies Tenant that it intends to move Tenant from the Expansion
Space to Alternate Space, Tenant may withdraw its Expansion Notice if Tenant
determines not to accept the Alternate Space offered by Landlord. Tenant shall
so advise Landlord by written notice given to Landlord within ten (10) Business
Days of the date of Landlord's Notice. If Tenant accepts the Alternate Space
offered by Landlord, (i) Landlord shall, at Landlord's cost, move Tenant to the
Alternate Space and shall pay, in connection therewith, for the cost of
installing telecommunications equipment in the Alternate Space in an amount not
to exceed $10,000 and (ii) the term "Expansion Space" as used in this Article 10
shall for all purposes hereunder mean the Alternate Space. Landlord shall
coordinate any move to the Alternate Space with Tenant, but the timing of such
move shall be determined in Landlord's sole discretion.

                  c. subject to any offsets or defenses which Tenant might have
            against any prior landlord (including Landlord), other than as
            specifically provided for in the Lease, provided the foregoing shall
            not relieve Lender from any obligation of the Landlord under the
            Lease accruing or arising after Lender's succeeding to the interest
            of Landlord under the Lease; or

                  d. bound by any rent or additional rent which Tenant might
            have paid in advance for more than the current month to any prior
            landlord (including Landlord); or

                  e. bound by any amendment or modification of the Lease made
            without Lender's written approval or consent not to be unreasonably
            withheld; or

                  f. bound by any representation or warranty made by any prior
            landlord (including Landlord).

            5. This Agreement shall bind and inure to the benefit of the parties
hereto and their respective successors and assigns.

            6. Tenant agrees to give Lender, by certified mail, return receipt
requested, sent to Lender's address set forth above a copy of any notice of
default served upon Landlord. Tenant further agrees that if Landlord shall have
failed to cure such default within the time provided for in the Lease and Tenant
would have the right to terminate the Lease based on such default then the
Lender shall have an additional thirty (30) days within which to cure such
default before Tenant may terminate the Lease, or if such default cannot be
cured within that time, then such additional time as may be necessary to cure
such default shall be granted if within thirty (30) days Lender has commenced
and is diligently pursuing to cure such default, in which event the Lease shall
not be terminated while such remedies are being so diligently pursued.

            7. The liability of Lender for the performance of any obligation of
Landlord under the Lease shall be limited to Lender's interest in the Demised
Premises and the income and proceeds therefrom, and Tenant hereby agrees that
any judgment it may obtain against Lender as a result of Lender's failure, as
Landlord, to perform any of Landlord's obligations under the Lease shall be
enforceable solely against Lender's interest in the Demised Premises.

      In connection with the purchase of such notes, the investors received on
      January 14, 1998 a warrant that allowed them, among other rights, to
      exchange the warrant for such number of shares of our common stock, at the
      time of and giving effect to such exchange, equal to 5.5% of the fully
      diluted number of shares of common stock outstanding, after giving effect
      to the exercise or conversion of all then outstanding options, warrants
      and other rights to purchase or acquire shares of common stock.

      For accounting purposes, we allocated approximately $1.4 million to the
      value of the warrant, based on a valuation by an investment banker. The
      warrant was included outside of Consolidated Shareholders' Equity, due to
      its cash put feature and the notes were recorded at a value of proceeds
      received less the value attributed to the warrant. The difference between
      the recorded value of the notes and the principal is being amortized as
      additional interest expense over the life of the notes. The warrant was
      exchanged and exercised for our common stock during the first quarter of
      1999.

5.    Our balance sheet at December 31, 1998 also reflects a contra
      shareholders' equity amount of $199,900, related to a loan made by us in
      August 1995 to a shareholder. The loan was repaid during the first quarter
      of 1999.

6.    We made no cash payments of interest or income taxes during the nine
      months ended September 30, 1998. However, we made cash interest payments
      in July 1999 of $369,632, related to the $5 million original fair value
      notes.

7.    For the three and nine months ended September 30, 1999, we incurred
      executive compensation expense of $2.1 million and $3.6 million,
      respectively. Approximately $1.3 million of both the three and nine month
      totals was non-cash compensation attributable to the exchange of stock
      options for stock appreciation rights, as described above. An additional
      component of total compensation expense was approximately $780,000 and
      $2.3 million for the three and nine month periods, respectively, related
      to an incentive compensation provision that is based on changes in the
      market value of our common stock during the twelve-month period ended
      March 31,1999. We are accruing the total value of the award in four equal
      quarterly amounts, beginning March 31, 1999, since it is payable in
      quarterly installments that are contingent on continued employment by us
      of the executive receiving this compensation. We have paid approximately
      $1.7 million, or 75% of the award in the form of our unregistered common
      stock.

8.    We have developed proprietary and patented software technologies for two
      principal business segments, Individualized Television and HyperTV.
      Individualized Television software provides the tools needed to create
      live or pre-recorded television programming that individualizes what the
      viewer sees and hears. We have not yet recorded revenues related to
      Individualized Television, applications of which we expect to distribute
      both nationally and regionally in the U.S. HyperTV software enables the
      simultaneous delivery of television video and complementary web content.
      HyperTV is targeted at both the entertainment and education markets. Our
      presentation of the operating segments, Individualized Television and

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

Overview

      Since our inception, the primary focus of our operating activities has
been to develop patented, proprietary technologies that enable programmers and
advertisers to create individualized programming and programming enhancements
--first for television and later also for the emerging area of
television/Internet convergence. We call our technologies for the television and
television/Internet convergence markets Individualized Television and
HyperTV(TM), respectively.

      We derived all of our revenues for 1998 and for the nine months ended
September 30, 1999 from HyperTV, which is targeted at the entertainment and
education markets. We anticipate that the most significant portion of future
HyperTV revenues will be derived from the entertainment market, for which we
introduced a HyperTV application earlier this year. We subsequently entered into
HyperTV programming alliances for this market with The Box Music Network,
Showtime, and New Line Television. We expect the sources of revenue from the
entertainment market to be software licensing and program hosting fees, Internet
advertising and commerce, content creation fees, and data management services.

      With respect to Individualized Television, our business plan is to
generate future revenues from subscription fees, advertising and fees related to
advertising services. For national distribution of Individualized Television, we
have formed a joint venture, LMC IATV Events, LLC, with Liberty Digital, a
subsidiary of Liberty Media Corporation. LMC expects to license the rights to
produce individualized telecasts of marquee sports and other events. In November
1999, LMC IATV Events entered into an agreement with Viewer's Choice, LLC to
distribute individualized event programming on a pay-per-view basis to a
national audience. Viewers Choice is the premier distributor of pay-per-view
programming in the United States.

      For regional applications of Individualized Television, we intend to
launch a series of sports television networks in different regions of the United
States. Programming for our networks will be provided by FOX Sports Net, which
reaches 72 million homes through 19 regional networks across the country. FOX
Sports Net will supply us with its professional and college sports programming,
to which we will add Individualized Television enhancements produced by us. Our
license agreement with FOX Sports Net provides that we pay FOX a portion of the
net subscriber revenue we receive from cable operators. In addition, we must
bear the production costs of additional elements to produce an individualized
telecast.

      Having performed tests of Individualized Television during 1998 and 1999
through the Dallas cable system of AT&T Broadband & Internet Services (formerly
TCI Cable), we intend to launch our first network in the region served by FOX
Sports Net Southwest. FOX Sports Net Southwest programming reaches over 6
million subscriber homes in Texas, Arkansas, Louisiana, Oklahoma and parts of
New Mexico. We have an agreement with AT&T Broadband to distribute our southwest
regional network and to share subscription fee revenues with us. Since
individualized programming relies on software incorporated into digital cable
set-top terminals, AT&T Broadband will offer our network to those subscribers
who receive its digital cable service. We intend to enter into similar
distribution agreements with other cable operators who are deploying digital
service in their systems.

      We have had minimal revenues to date and have incurred significant
operating losses, net

preferred stock issued by a subsidiary of ours, which was accounted for as
minority interest. In addition, we paid $312,137 in preferred dividends during
the nine-month period ending September 30, 1998 in the form of our common stock.
The subsidiary preferred stock was retired in November 1998 in exchange for a
combination of our new preferred stock, common stock and warrants.

      Preferred Stock Dividends. For the nine-month period ended September 30,
1999, we paid $494,431 in preferred stock dividends, related to our Series B
preferred stock, compared to no such preferred dividend payments during the
comparable 1998 period. The Series B preferred stock, which was issued in
November 1998, was redeemed in full in May 1999.

      Net Loss Applicable to Common Shareholders. For the nine months ended
September 30, 1999, our net loss applicable to common shareholders was
$16,407,091 or $.47 per basic and diluted share, an increase of 66% over the net
loss of $9,869,022, or $.51 per basic and diluted share, incurred in the prior
year's comparable period. The increase during the more recent nine-month period
was the result of higher overall expenses, led by higher selling and
administrative and stock appreciation rights expenses, as described above.

Comparison of Nine-Month Periods Ended September 30, 1998 and September 30, 1997

      Revenues. During the nine-month period ended September 30, 1998, our
revenues decreased 31% to $1,058,560, from $1,534,295 in the nine-month period
ended September 30, 1997. Nearly all of our revenues in the more recent
nine-month period were derived from educational sales of HyperTV software,
computer servers, and related services, compared to the comparable 1997
nine-month period, when the majority of revenues were related to
television-based education hardware and content.

      Total Costs and Expenses. Cost of sales in the nine months ended September
30, 1998, was $168,934, a decrease of 61% over cost of sales of $434,287 in the
nine months ended September 30, 1997. The decrease was the result of the change
in the composition of products sold during the nine months ended September 30,
1998, as noted above, in favor of Internet products and services, which carry a
higher profit margin than our television-based education revenue sources. Total
costs and expenses, excluding cost of sales, in the nine months ended September
30, 1998, increased 63%, to $9,766,665, from $6,000,435 in the comparable period
in 1997. The increase was due to higher operating and selling and administrative
expenses associated with our regional network testing in Dallas; higher
depreciation and amortization expenses; and higher stock appreciation rights
expenses, the result of an increase in the market price of our common stock.
Depreciation and amortization expense for the nine months ended September 30,
1998, increased 440% to $810,984, from $150,210 for the nine months ended
September 30, 1997. This increase was due principally to higher depreciation
expenses related to our regional network's master control production facility
and to the amortization of software development costs in the more recent period.

      Interest Expense (Income) - Net. Interest income in the nine months ended
September 30, 1998, was $105,398, compared with $103,239 in the nine months
ended September 30, 1997. We incurred interest expense and accretions of
$718,220 in the nine months ended September 30, 1998, compared to no interest
expense during the comparable 1997 period. Interest expense is related to the $5
million principal value notes issued in January 1998 by a subsidiary of ours. We
chose to pay the interest due September 30, 1998 in kind rather than in cash.

outstanding preferred stock issued by our subsidiary, which was accounted for as
minority interest. The subsidiary preferred stock was retired in November 1998
in exchange for a combination of new ACTV, Inc. preferred stock, common stock,
and warrants.

      Net Loss Applicable to Common Shareholders. Our net loss applicable to
common shareholders for the three months ended September 30, 1999 decreased
approximately 11%, to $3,424,802, or $.08 per share, from $3,833,484, or $.16
per share, in the comparable 1998 period, principally due to higher sales, SARs
income and interest income that more than offset an increase in selling and
administrative expenses.

Comparison of Three-Month Periods Ended September 30, 1998 and September 30,
1997

      Revenues. During the three-month period ended September 30, 1998, our
revenues increased approximately 58%, to $301,900, from $191,400 in the
three-month period ended September 30, 1997. In the 1998 quarter, all of our
revenues derived from HyperTV sales, compared to the 1997 quarter, in which we
recorded revenues from both HyperTV sales and from television-based education
hardware and content.

      Total Costs and Expenses. Cost of sales in the three months ended
September 30, 1998 was $45,545, compared to corresponding 1997 quarter's cost of
sales of $78,847. The difference was due to the relatively higher gross margins
of our HyperTV products. Total costs and expenses, excluding cost of sales,
increased approximately 124% for the three months ended September 30, 1998, to
$3,758,462, from $1,681,306 for the three months ended September 30, 1997. The
increase was due principally to higher operating, selling and administrative
expenses and depreciation and amortization expense in the more recent period.
The increases were principally related to our Southwest regional network.
Depreciation and amortization expense increased 474% for the three months ended
September 30, 1998 to $296,721, from $51,722 in the comparable 1997 quarter.
This increase was due principally to higher depreciation expenses related to the
regional network's master control production facility.

      Interest Expense (Income) -- Net. Interest income for the three months
ended September 30, 1998 was $40,077, compared with $11,156 for the three months
ended September 30, 1997. The increase was due to higher average cash balances
during the more recent period. We incurred interest expense and accretions of
$254,243 in the 1998 quarterly period, compared to no interest expense during
the comparable 1997 period. Interest expense is related to the Notes issued in
January 1998 by a subsidiary of ours. We chose to pay the interest due September
30, 1998 in kind rather than in cash.

      Minority Interest -- Subsidiary Preferred Stock Dividends. For the three
months ended September 30, 1998 and the three months ended September 30, 1997,
respectively, we accrued $117,211 for dividends and $746,041 for dividends and
accretions, respectively, related to outstanding preferred stock issued by our
subsidiary, which was accounted for as minority interest. We paid $117,211 and
$746,041 in preferred dividends during the three-month periods ending September
30, 1998 and September 30, 1997, respectively, by issuing shares of our common
stock.

      Net Loss. Our net loss for the three months ended September 30, 1998
increased approximately 66%, to $3,833,484, or $.16 per share, from $2,303,598,
or $.17 per share, in the comparable 1997 period, principally due to higher
expenses associated with our regional network, as noted above.

Year 2000 compliance

      The year 2000 issue is the result of computer software that was written
with only two digits rather than four digits to represent the year in a date
field. Computer hardware and software applications that are date-sensitive may
interpret a date represented as "00" to be the year 1900 rather than the year
2000. The result could be system failure or miscalculations causing the
disruption of operations.

      We believe that our internal systems, relating to both computer hardware
and software, will function properly with respect to dates in the year 2000 and
beyond. In addition, we believe that our proprietary software either sold
directly to third parties or incorporated in products sold to third parties is
year 2000 compliant. Having performed an assessment of the potential year 2000
problem, we do not expect to incur significant costs related to year 2000
issues.

      However, there is general uncertainty regarding the year 2000 problem and
its effect on the overall business environment. We cannot determine at this time
whether the year 2000 problem will have a material impact on our operations or
financial condition as the result of significant disruptions to the U.S. economy
and/or business infrastructure.
