the fair and reasonable rental value of the demised premises for the same
period, In the computation of such damages the difference between any
installment of rent becoming due hereunder after the date of termination and the
fair and reasonable rental value of the demised premises for the period for
which such installment was payable shall be discounted to the date of
termination at the rate of four percent (4%) per annum. If such premises or any
part thereof, before presentation of proof of such liquidated damages to any
court, commission or tribunal, the amount of rent reserved upon such reletting
shall be deemed to be the fair and reasonable rental value for the part or the
whole of the premises so re-let during the term of the re-letting. Nothing
herein contained shall limit or prejudice the right of the Owner to prove for
and obtain as liquidated damages by reason of such termination, an amount equal
to the maximum allowed by any statute or rule of law in effect at the time when,
and governing the proceedings in which, such damages are to be proved, whether
or not such amount be greater, equal to, or less than the amount or the
difference referred to above.

of the Tenant shall also pay Owner as liquidated damages for the failure of
Tenant to observe and perform said Tenant's covenants herein contained, any
deficiency between the rent hereby reserved and / or covenanted to be paid and
the net amount, if any, of the rents collected on account of the lease or leases
of the demised premises for each month of the period which would otherwise have

receive any excess, if any, of such net rents collected over the sums payable by

if re-entry, summary proceedings and other remedies were not herein provided

from any other remedy, in law or in equity. Tenant hereby expressly waives any
and all rights of redemption granted by or under any present or future laws in

Tenant in the covenant to pay rent hereunder, makes any expenditures or incurs
any obligations for the payment of money, including but not limited to
attorney's fees, in instituting, prosecuting or defending any action or
proceeding, then Tenant will reimburse Owner for such sums so paid or
obligations incurred with interest and costs. The foregoing expenses incurred by
reason of Tenant's default shall be deemed to be additional rent hereunder and
shall be paid by Tenant to Owner within five (5) days of rendition of any bill
or statement to Tenant therefore. If Tenant's lease term shall have expired at
the time of making of such expenditures or incurring of such obligations, such
sums shall be recoverable by Owner as damages.

Building Alterations & Management:

20.  Owner shall have the right at any time without the same constituting an
eviction and without incurring liability to Tenant therefore to change the
arrangement and / or location of public entrances, passageways, doors, doorways,
corridors, elevators, stairs, toilets or other public parts of the building and
to change the name, number or designation by which the building may be known.
There shall be no allowance to Tenant for diminution of rental value and no
liability on the part of Owner by reason of inconvenience, annoyance or injury
to business arising from Owner or other Tenants making any repairs in the
building or any such alterations, additions and improvements. Furthermore,
Tenant shall not have any claim against Owner by reason of Owner's imposition of
such controls of the manner of access to the building by Tenant's social or
business visitors as the Owner may deem necessary for the security of the
building and its occupants.

No Representation by Owner:

21.  Neither Owner nor Owner's agents have made any representations or promises
with respect to the physical condition of the building, the land upon which it
is erected or the demised premises, the rents, leases, expenses of operation or
any other matter or thing affecting or related to the premises except as herein
expressly set forth and no rights, easements or licenses are acquired by Tenant
by implication or otherwise except as expressly set forth in the provisions of
this lease, Tenant has

                                      -9-
<PAGE>

inspected the building and the demised premises and is thoroughly acquainted
with their condition and agrees to take the same "as is" and acknowledges that
the taking of possession of the demised premises by Tenant shall be conclusive
evidence that the said premises and the building of which the same form a part
were in good and satisfactory condition at the time such possession was so
taken, except as to latent defects. All understandings and agreements heretofore
made between the parties hereto are merged in this contract, which alone fully
and completely expresses the agreement between Owner and Tenant and any
executory agreement hereafter made shall be ineffective to change, modify,
discharge or effect an abandonment of it in whole or in part, unless such
executory agreement is in writing and signed by the party against whom
enforcement of the change, modification, discharge or abandonment is sought.

End of Term:

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

Quiet Enjoyment:

23.  Owner covenants and agrees with Tenant that upon Tenant paying the rent and
additional rent and observing and performing all the terms, covenants and
conditions, on Tenant's part to be observed and performed, Tenant may peaceably
and quietly enjoy the premises hereby demised, subject, nevertheless, to the
terms and conditions of this lease including, but not limited to, Article 31
hereof and to the ground leases, underlying leases and mortgages hereinbefore
mentioned.

Failure to Give Possession:

24.  If Owner is unable to give possession of the demised premises on the date
of the commencement of the term hereof, because of the holding-over or retention
of possession of any tenant, undertenant or occupants or if the demised premises
are located in a building being constructed, because such building has not been
sufficiently completed to make the premises ready for occupancy or because of
the fact that a certificate of occupancy has not been procured or for any other
reason, Owner shall not be subject to any liability for failure to give
possession on said date and the validity of the lease shall not be impaired
under such circumstances, nor shall the same be construed in any wise to extend
the term of this lease, but the rent payable hereunder shall be abated (provided
Tenant is not responsible for Owner's inability to obtain possession) until
after Owner shall have given Tenant written notice that the premises are
substantially ready for Tenant's occupancy. If permission is given to Tenant to
enter into the possession of the demised premises or to occupy premises other
than the demised premises prior to the date specified as the commencement of the
term of this lease, Tenant covenants and agrees that such occupancy shall be
deemed to be under all the terms, covenants, conditions and provisions of this
lease, except as to the covenant to pay rent. The provisions of this article are
intended to constitute "an express provision to the contrary" within the meaning
of Section 223-a of the New York Real Property Law.

No Waiver:

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

Waiver of Trial by Jury:

26.  It is mutually agreed by and between Owner and Tenant that the respective
parties hereto shall and they hereby do waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties hereto against the
other (except for personal injury or property damage) on any matters whatsoever
arising out of or in any way connected with this lease, the relationship of
Owner and Tenant, Tenant's use of or occupancy of said premises, and any
emergency statutory or any other statutory remedy. It is further mutually agreed
that in the event Owner commences any summary proceeding for possession of the
premises, Tenant will not interpose any counterclaim of whatever nature or
description in any such proceeding including a counterclaim under Article 4.

Inability to Perform:

27.  This Lease and the obligation of Tenant to pay rent hereunder and perform
all of the other covenants and agreements hereunder on part of Tenant to be
performed shall in no wise be affected, impaired or excused because Owner is
unable to fulfill any of its obligations under this lease or to supply or is
delayed in supplying any service expressly or impliedly to be supplied or is
unable to make, or is delayed in making any repair, additions, alterations or
decorations or is unable to supply or is delayed in supplying any equipment or
fixtures if Owner is prevented or delayed from so doing by reason of strike or
labor troubles or any cause whatsoever including, but not limited to, government

agency or by reason of the conditions of supply and demand which have been or
are affected by war or other emergency.

     37.   The Landlord agrees that the Tenant may occupy the demised premises
free of base rent from the commencement date December 1, 2000 through December
31, 2000. The within rent concession shall apply to base rent, and shall include
the sprinkler, water and sewer for a total of $12,940.00. Moreover, the
concessions granted pursuant to this paragraph are intended to be amortized over
the term of this Lease, notwithstanding the fact that they are realized by the
Tenant at the inception of this Lease. In the event this Lease is terminated or
possession surrendered before the expiration date as a result of Tenant's
default hereunder, the full concession shall become immediately due and payable
and a debt to be charged against the Tenant as additional rent or otherwise,
along with any unamortized brokerage commission which has been paid by Landlord.

     Therefore, at the date of execution of this Lease, the Tenant shall pay to
Landlord, and Landlord acknowledges receipt of the following:

     January 1, 2001 Rent......................  $12,840.00
     January 1, 2001 Water and Sewer...........  $    70.00
     January 1, 2001 Sprinkler.................  $    30.00
     Proportionate share BID...................  $   201.50
     Security Deposit (last 4 months charges)..  $58,206.12
                                                 ----------
     Total upon signing of Lease...............  $71,347.62

     The security deposit will be held in an interest-bearing "lease security"
account in HSBC Bank USA.   Interest is to be paid annually to Tenant on or
about March 30 of each year, less a one (1%) percent administrative fee to be
retained by Landlord.  Landlord reserves the right to change the bank in which
the deposit is mentioned and shall notify Tenant of any such change.  Landlord
shall
<PAGE>

not be required to obtain an interest rate above that normally given by the bank
for ordinary lease security accounts.

     Rent:  Method of Payment:   The rent is due, in the Landlord's office, on
     ------------------------
the First (1st) day of each and every month.   On the First (1st) day of each
month (or, if that is a non-business day, on the first business day thereafter),
a messenger from the Landlord will pick up the rent from the Tenant's premises.
Rent shall be paid in U.S. currency in good funds in cash or check drawn on a
bank with an office in New York City.

     Rent:  Late Payment:  Rent not received by the Landlord by 3:00 p.m. on the
     -------------------
Seventh (7th) calendar day of each month shall be deemed in default.  In
addition, in the event the full rent is not received by the owner by the Seventh
(7th) calendar day of each month, the Tenant shall pay a late charge equal to
four (4%) percent of the outstanding balance of unpaid rent and/or additional
rent due pursuant to this Lease.

     In the event any check given by Tenant to Landlord is dishonored by
Tenant's bank, for any reason, Tenant shall forthwith deliver a certified or
bank check to Landlord in the amount of the dishonored check together with any
applicable late payment charge, plus a charge of Twenty-five Dollars ($25), upon
receipt of which Landlord will return the dishonored check to Tenant.

     The charges herein set forth shall be deemed reimbursement to Landlord for
expenses incurred and lost income which may result from such late payments and
not as a penalty. The charges herein shall be in addition to and not in lieu of
any other rights of Landlord granted by this Lease or by law.

     38.  (a)  For the purpose of this Paragraph, it is agreed that the area
occupied by Tenant under this Lease represents 3.35% percent of the total
rentable area of the building, of which the demised premises are a part
(hereinafter referred to as the building); that the "lease year" shall mean the
twelve (12) month period commencing with the first day of the term and each
twelve (12) month period thereafter; that the "Base" tax year for determining
the increase in taxes and vault charges, shall be the tax year 2000/2001, the
"Base" year for determining all charges in subparagraph (b) below shall be
Calendar year 2000.

     (b) In addition to all other rent charges payable by Tenant under this
Lease, Tenant agrees to pay 3.35% percent of the amount of any increase in
Landlord's expense on the building for real estate taxes, common vault charges
and fuel charges imposed on the building (including the land thereunder) in any
subsequent year over the amount of the fuel costs and taxes, common vault
charges paid or required to be paid by Landlord for the Base tax year, by reason
of any increase in the assessed valuation or an increase in the tax rate, or
both, or by the levy, assessment or imposition of any new or additional real
estate tax or assessment on the building and/or appurtenances (including the
land thereunder) to the extent that same shall be in lieu of or in addition to
any of aforesaid taxes or assessments upon or against said building and/or
appurtenances (including the land thereunder) or by any increase in the vault
charges. The Tenant agrees to pay the amount of any such increase within twenty
(20) days following receipt of Landlord's bill for same. If any such increase
shall be applicable to less than a full lease year, the increase shall be pro-
rated. Landlord shall, at the time it sends Tenant a bill for the aforesaid tax
increase, enclose a copy of the most recent fuel bill and the most recent tax
and related bills from the City of New York and indicate how Landlord computes
Tenant's share of any tax increase.

                                      -2-
<PAGE>

     (c) In addition to the above, Tenant shall be responsible for Tenant's
proportionate share 3.35% of any Business Improvement District Charge (B.I.D.)
or tax imposed upon the building.

     (d) In no event shall the annual rent stated in this Lease (exclusive of
additional rent under this article) be reduced for any year below the amount
specified therefor in paragraph 36 for such year.

     39.  If electric current is supplied by Landlord and is submetered to the
Tenant who shall purchase same from Landlord or Landlord's agent at the same
base rate which Landlord pays to Consolidated Edison Company (Rate #4) plus
Twenty-five Percent (25%).

     Landlord shall not be liable to Tenant for any loss or damage or expense
which Tenant may sustain or incur if either the quantity or character of
electric service is changed or is no longer available or suitable for Tenant's
requirements as a result of causes beyond Landlord's reasonable control. Any
riser or risers to supply Tenant's electrical requirements, upon written request
of Tenant, and written approval of Landlord may be installed by Tenant, at the
sole cost and expense of Tenant, if, in Landlord's sole reasonable judgment, the
same are necessary and will not cause permanent damage or injury to the building
or demised premises or cause or create a dangerous or hazardous condition or
entail excessive or unreasonable alterations, repairs or expense or interfere
with or disturb other tenants or occupants. In addition to the installation of
such riser or risers, Tenant will also at the sole cost and expense of Tenant,
install all other equipment proper and necessary in connection therewith subject
to the aforesaid terms and conditions.  Tenant covenants and agrees that at all
times its use of electrical current shall never exceed the capacity of existing
feeders to the building or the risers or wiring installations.

     Bills shall be rendered at such times as Landlord may elect. In the event
that such bills are not paid within five (5) business days after they are
rendered, Landlord may, after five (5) business days written notice to Tenant in
accordance with paragraph 59, discontinue the service of electric current to the
demised premises.  Since Landlord is liable to Con Edison for payment of the
bills even in the event Tenant defaults, Landlord's election to employ this
remedy shall not be considered a breach of agreement and shall not entitle
Tenant to any offset of rent.

     Landlord may also discontinue the service of electric current to the
demised premises without cause upon thirty (30) days written notice to Tenant,
however, in such event, Landlord will continue to supply electric service until
Tenant has had a reasonable time to obtain same directly from the Utility. In
the event of discontinuance of electric service by the Landlord, as hereinabove
provided, Landlord shall have the option to install a meter at its sole cost and
expense and other appropriate wiring to insure that Tenant's electrical service
is not interrupted.  In such event Tenant shall not be released from any
liability under this Lease.  Such discontinuance shall not be deemed to be a
lessening of services within the meaning of any law, rule, or regulation now or
hereafter enacted, promulgated or issued. In the event of such discontinuance,
Tenant shall arrange to receive such service directly from said public utility
corporation.

     If any tax is imposed upon Landlord's receipt from the sale or resale of
electrical energy or gas or telephone service to the Tenant by any Federal,
State or Municipal Authority, Tenant covenants and agrees that, where permitted
by law, Tenant's pro rata share of such taxes shall be passed on to, and
included in the bill of, and paid by, Tenant to Landlord.

                                      -3-

     40.  It is understood and agreed that this Lease may not be assigned nor
may the demised premises be sub-leased without the Landlord's written consent.
Furthermore, it is understood and agreed that, unless Tenant is a publicly-
traded company, in the event Tenant sells, assigns, or transfers any ownership
of any shares of its stock to any person or entity without the prior written
consent of Landlord, whose consent shall not be unreasonably withheld and/or
delayed, same shall be deemed an unauthorized assignment. However, it is
understood and agreed that in the event Landlord consents to any such
assignment, sublet or transfer same shall not diminish Tenant's obligation to
perform all the terms, warranties, and covenants.  Such assignment shall not
                                                                         ---
relieve tenant of its obligations or duties hereunder.

     Notwithstanding the above, at Landlord's option, where Tenant proposes to
Sublet or Assign all of the Demised Premises, Landlord may elect to terminate
this Lease in lieu of giving consent, whereupon all obligations of the parties
shall terminate on all respects.  Landlord, if it so elects, shall exercise this
option within Twenty-One (21) days of receipt of a written request for
permission to Sublet or Assign from the Tenant received in accordance with
Paragraph 59 of this Lease.  Tenant has no reciprocal option to Terminate.  Upon
such Termination, the provisions of this lease applicable to the end of the term
shall be accelerated to the date the Tenant proposed such Sublet or Assignment
were to be effective.  In the event Landlord makes such election, Tenant shall
remain fully responsible for all terms of this Lease until the accelerated
Termination thereof.  Tenant shall further be responsible for all unamortized
brokerage commissions and rent concessions as per paragraph 37 in the event of
any accelerated termination of this Lease pursuant to this paragraph.

     In the event Tenant does sell, assign or transfer this Lease or sublet any
part of the demised premises with Landlord's consent as hereinbefore provided
for a sum in excess of the base rent as herein provided Landlord shall be
entitled to receive one-half ( 1/2) of any such excess base rent, net of any
expense which Tenant may incur in renting same, including, without limitation,
brokerage commissions, legal fees and the cost of Tenant's leasehold
improvements. Such excess shall be determined by dividing the rent (base and
additional) paid by Tenant by the number of square feet of the demised premises
in order to determine a rent per square foot. If the rent per square foot
pursuant to the sublease or lease assignment exceeds the rent per square foot
pursuant to this Lease less the aforementioned expenses, Landlord shall be
entitled to one-half ( 1/2) of such excess.

     In the event of an assignment to a subsidiary, parent, partner, affiliated
company or other alter-ego of Tenant, Tenant shall remain liable for the
performances of all obligations pursuant to this Lease.   Any such assignment
shall be permitted without Landlord's consent, except Landlord must be notified
in advance of such assignment and such assignment shall not relieve either the
Tenant or any Guarantor from its obligations hereunder.

     Any other assignment must be done in strict compliance with this paragraph.

     Under no circumstances shall the rent be below that which is reserved by
this Lease.

     41.  Tenant shall, at its sole cost and expense, provide and keep in full
force and effect for the benefit of Landlord and Tenant, a liability insurance
policy (naming Landlord as additional insured) in the amount of One Million
($1,000,000) Dollars for any one loss - Said policy shall be in standard form
written by good and solvent insurance companies reasonably satisfied to
Landlord, protecting Landlord and Tenant against any and all liabilities due to
or occasioned by negligence, occurrence, accident, or disaster on or about the
demised premises.

                                      -4-
<PAGE>

     42.  All certificates of insurance shall be delivered to and left in the
possession of Landlord prior to the commencement of this lease or the
commencement of any work performed in or on the demised premises whichever date
shall be earlier. Such insurance shall be reasonably satisfactory to Landlord
and shall contain a clause requiring notification in writing by Certified Mail,
Return Receipt Requested, on ten (10) business days notice to Landlord in the
event of cancellation thereof for any reason whatsoever.

     Said policies of insurance shall contain a provision waiving rights of
subrogation as against Landlord.

     43.  It is understood that in the event an insurance company providing
Landlord with insurance for the building in which the demised premises
constitutes a part shall at any time after the commencement of this lease
increase the annual premium for the amount of coverage then in place because of
Tenant's manner of use of the demised premises, other then for office space,
Tenant shall pay to Landlord as "Additional Rent", collectible in the same
manner and method as Rent is collected hereunder, One Hundred (100%) Percent of
such increase, due and payable on the first day of the first month subsequent to
Landlord's notification to Tenant that Landlord has received notification of
such increase.   This paragraph shall not apply to changes in insurance rates
due to the premises being occupied rather than vacant, but refers to any
increases due to Tenant's activities or use of the premises.

     44.  Intentionally Omitted.

     45.  The Landlord will provide steam heat to the premises between October
15 and May 15 and from 7:00 a.m. to 6:00 p.m., Monday through Friday, when the
outside temperature falls below 55F. On Saturday, Sunday, legal Holidays, and
between the hours of 5:00 p.m. to 7:00 a.m., the Landlord will provide heat only
if the outside temperature falls below 40F. In the event of a mechanical
breakdown of the heating equipment, the owner shall not be responsible for any
loss of income or damages sustained by the Tenant. The owner agrees to make
prompt repairs to the heating equipment, provided same is within the owner's
reasonable control.

     The Tenant may install a supplementary heating system, which is capable of
heating the entire demised premises when steam heat is not provided by the
owner. The Tenant's use of the supplementary heat shall be at the sole option,
control, and expense of the Tenant. The heating system shall be installed and
operated in accordance with any and all governmental laws and regulations
pertaining thereto. In the event the Tenant desires to use gas for said
supplementary heating system, the Tenant will first obtain a "blue card" and Con
Edison gas meter through the services of a licensed plumber.

     In no respect is Landlord required to maintain the premises at a specified
temperature and the Tenant agrees to accept such heat as is normally supplied in
office buildings.

     In no event shall the Landlord's failure to provide heat due to technical
problems be a cause for offset, diminution or suspension of Tenant's rental
obligations.  In no respect is Landlord required to maintain the premises at a
specified temperature.

     46.  In order to properly service and maintain the sprinkler system for the
entire building, the Landlord must gain access to certain sprinkler valves
within Tenant's premises. The Tenant shall permit reasonable access by
Landlord's agents or employees to the valves during normal business

                                      -5-

services equipment, and labor required for any work performed by Tenant or
performed by Landlord on Tenant's behalf to the demised premises shall be
supplied by Tenant at Tenant's sole cost and expense, unless specifically
excepted herein. Furthermore, it is understood and agreed that Tenant shall make
no demands upon Landlord for the provision of any supplies, materials, services,
equipment, or labor, nor shall Tenant request from Landlord any form of
compensation for Tenant's expenditures, unless specifically provided for herein.

     49.  It is understood and agreed that any and all work done by Tenant to
the demised premises shall be in accordance with all laws, regulations, and
ordinances of all governmental or municipal agencies having jurisdiction
therein.

     50.  Tenant, and it assigns, shall indemnify and hold Landlord harmless
from and against all liabilities, obligations, damages, penalties, claims,
costs, and expenses, including reasonable attorneys' fees paid, suffered, or
incurred arising out of or from any occurrence, accident, or disaster in the
demised premises, or in and about or adjacent to the exterior of the building in
which the demised premises constitutes a part, causing injury or damage to any
person, entity, or property, due to, any neglectful act or neglect of Tenant,
its agents, servants, employees, customers, or visitors to comply with and
perform each and every requirement and provision of this lease on its part to be
performed or due or claimed to be due to any use made by Tenant of the demised
premises. The foregoing indemnity shall not apply to the extent that Landlord
shall be determined to be contributorily negligent in respect of any occurrence,
accident or disaster in or about the demised premises.

     51.  Tenant agrees to use its best efforts to maintain the demised premises
free of any violations that may be imposed by the Department of Buildings and/or
any other governmental or municipal agency having jurisdiction over the demised
premises, arising out of Tenant's manner of use of the demised premises
hereunder which affect Landlord's building.

     52.  It is understood and agreed that Tenant will only use the demised
premises for General Office use and for no other purpose. Tenant acknowledges
that any breach of the foregoing provision will cause Landlord substantial and
irreparable harm and damage. In addition to all other remedies available to
Landlord, it is understood and agreed that this Lease and the term hereof shall
end, expire, and terminate in the event such breach is not cured within ten (10)
business days after notice by Landlord to Tenant to cure said breach as served
pursuant to paragraph 59 hereof.  In the event such notice is given, Tenant
hereby agrees to vacate and surrender the demised premises to Landlord
forthwith.  If tenant fails to do so landlord may seek an eviction by summary

     53.  It is understood and agreed that in the event Tenant shall "Hold Over"
and fail to deliver the demised premises to Landlord vacant and in "Broom Clean"
condition at the expiration of this Lease, at the expiration of any extensions
of this Lease, or at any time Landlord shall gain legal possession of the
demised premises by reason of Court Order, Tenant's default, or for any other
rea-

                                      -6-
<PAGE>

son whatsoever, such "Holding Over" shall not be deemed to extend the term or to
renew this Lease, but such "Holding Over" thereafter shall continue upon the
covenants and conditions herein set forth except that the charge for the use and
occupancy of such "Holding Over" for each calendar month or part thereof (even
if such part shall be a small fraction of a calendar month) shall be at the rate
of 2 times the aggregate rent and additional rent payable hereunder during the
last month of Tenant's legal occupancy, which total sum Tenant agrees to pay
Landlord promptly upon demand, in full, without set-off or deduction. In the
event Tenant shall fail to pay Landlord such charge for "Holding Over" promptly
upon Landlord's demand, as provided for hereinabove, it is understood and agreed
that Landlord shall be entitled to interest calculated at a daily periodic rate
of .0411, an annual percentage rate of Fifteen (15%) percent. Neither the
billing nor the collection of use and occupancy charges in the above amount
shall be deemed a waiver of any right of Landlord to collect damages for
Tenant's failure to vacate the demised premises after the expiration or sooner
termination of this Lease. The foregoing shall survive the term of this Lease
and any renewals or extensions thereof.

     54.  It is understood and agreed that the demised premises is used

Tenant shall receive reasonable advance notice thereof and that Landlord and its
agents and employees and all such persons shall use their best efforts not to
unreasonably interfere with the conduct of Tenant's business and Tenant's
occupancy of the demised premises. Tenant's failure to comply with this
provision shall be deemed a substantial breach of this Lease and sufficient
grounds for the summary termination of this Lease. Landlord agrees that except
in the event of an emergency requiring immediate entry, it will give Tenant
reasonable notice if Landlord desires to inspect or otherwise gain access to the
demised premises, provided that Tenant shall receive reasonable advance notice
thereof and that Landlord and its agents and employees and all such persons
shall use their best efforts not to unreasonably interfere with the conduct of
Tenant's business and Tenant's occupancy of the demised premises.

     Furthermore, in the event Tenant shall fail to provide Landlord with access
as provided for hereinabove and in the event Landlord, in its sole and
reasonable discretion, shall deem it necessary to enter the demised premises
forcibly for any reason whatsoever, Landlord may forcibly enter the demised
premises without any liability to Tenant in the event of any emergency and
Landlord shall repair any damage caused by such forcible entry with whatever
workmen and with whatever materials and in whatever manner Landlord, in its
reasonable discretion, may deem advisable provided such repairs are done in a
workmen like manner.   Landlord shall use reasonable efforts not to damage the
demised premises and the property of Tenant located therein provided that Tenant
shall receive reasonable advance notice thereof and that Landlord and its agents
and employees and all such persons shall use their best efforts not to
unreasonably interfere with the conduct of Tenant's business and Tenant's
occupancy of the demised premises.

under this Lease, "AS IS" vacant and broom clean, in their present state and
condition, and Landlord will have no obligations to

     a)   Space is accepted "as is".

     Tenant's work:

     a)   Tenant is not under any obligation to do any interior improvements,

in accordance with the Tenant's obligation under this Lease.

     b)   Tenant assumes all responsibility for maintenance and repair of the
interior modular furniture system which is currently in the premises.  During

good condition, reasonable wear and tear excepted.  Tenant takes possession of
the system in its "as is" condition and Landlord is not required to make any

     57.  Tenant hereby expressly grants to Landlord an easement and shall

conduits, plumbing, vents and wires in, to and through the premises as and to
the extent that Landlord may now or hereafter deem to be necessary or
appropriate for the proper operation and maintenance of the building in which
the demised premises are located or to the extent necessary to accommodate the
requirements of other Tenants in the building. All such work shall be done, so
far as practicable, in such manner as to avoid unreasonable interference with
Tenant's use of the premises. Landlord shall grant Tenant access to the plumbing
and electrical systems in the building to the extent that it can so as to allow
the hookup of the Tenant's plumbing and electrical installations.

     58.  The parties represent that no broker was instrumental in consummating

Landlord and Tenant each agree to indemnify and to hold the other harmless
against any claims for brokerage commissions arising out of any conversations or
negotiations had by the indemnifying party with any broker regarding these
premises. This indemnity shall include any claim and any of the indemnified
party's expenses arising out of such claims, including, but not limited to,
attorneys' fees.

     60.  In the event of any conflict between the provisions of this rider and
the printed "Boilerplate" Lease, the provisions of this rider shall prevail.

     61.  The failure of any party to insist upon the strict performance of a
party to exercise any right, option or remedy hereby reserved shall not be
construed as a waiver for the future of any such provision, right, option or
remedy or as a waiver of a subsequent breach hereof. The consent or approval by
the Landlord of any act by Tenant requiring the Landlord's consent or approval
shall not be construed to waiver or render unnecessary the requirement for the
Landlord's consent or approval of any subsequent similar act by the Tenant. The
receipt and acceptance by the Landlord of rent or other payments, charges or
sums with knowledge of a breach of any provision of this Lease Agreement shall
not be deemed a waiver of such breach. No provision of this Lease Agreement
shall be deemed to have been waived unless such waiver shall be in writing
signed by the party to be charged. No payment by the Tenant or receipt by the
Landlord of a lesser amount than the rents, charges and other sums hereby
reserved shall be deemed to be other than on account of the earliest rents,
additional rents due hereunder, charges and other sums then unpaid, nor shall
any endorsement or statement on any check or any letter accompanying any check
or payment by Tenant be deemed an accord and satisfaction, and such rents,
charges and other sums shall remain due and Landlord may pursue any other remedy
in this Lease Agreement provided or by law permitted, and no waiver by Landlord
in favor of any other Tenant or occupant shall constitute a waiver in favor of
the Tenant herein. No agreement to accept a surrender of all or any part of
demised premises or this Lease Agreement shall be valid unless in writing and
signed by the Landlord and the Tenant. No delivery of keys shall operate as a
termination of this Lease Agreement or a surrender of the demised premises.

     62.  Tenant agrees not to use or permit the demised premises to be used for
parties of any kind, except office parties, nor to permit the maintenance of any
pets or permit the demised premises to be used as residential space or living
quarters.

     63.  Tenant may install only such locks on the demised premises as are
approved by law, rule or ordinance for premises of the type designated in the
use clause of this lease and further agrees to see to it that all fire exits
remain unobstructed at all times. Tenant further agrees to enforce all laws,
rules or ordinances regulating permitted smoking areas in the demised premises.
Tenant shall be responsible for installation and the cost and expense of all
locks and security devices (i.e. alarms, etc.), and the maintenance thereof.
Landlord is not responsible for any damage or loss to tenant by theft,
vandalism, etc.  Tenant shall further be responsible to lock the elevator
security doors on the Third Floor and the elevator key switch in the lobby
whenever it is the last tenant to leave the floor at the end of the day.

     Tenant shall provide adequate fire extinguishers which shall be regularly
inspected at its sole cost and expense.

     64.  Landlord shall provide, at no cost to Tenant, two (2) keys to the

fifteen ($15) dollar deposit for each extra

key. In addition, Landlord shall give Tenant two (2) listings on the building
directory without charge. Up to two (2) additional listings may be had at
Twenty-Five ($25) Dollars per line.

     65.  Landlord and Tenant agree to give up the right to a trial by jury in
any court action, proceeding or counterclaim on any matters concerning this
Lease, the relationship of Tenant and Landlord or Tenant's use or occupancy of
the demised premises.

     66.  Tenant shall and hereby does waive its right and agrees not to
interpose any counterclaim or set off, of whatever nature or description, in any
proceeding or action that may be instituted by Landlord against Tenant to
recover rent, additional rent, other charges, possession, or for damages, or in
connection with any matters or claims whatsoever arising out of or in any way
connected with this Lease, or any renewal, extension, holdover, or modification
thereof, or the relationship of Landlord and Tenant, or Tenant's use of
occupancy of said premises.  This clause, as well as the "waiver of jury trial"
provision of this Lease, shall survive the expiration, early termination, or
cancellation of this Lease or the term thereof.  Nothing herein contained,
however, shall be construed as a waiver of Tenant's right to commence a separate
action on a bona fide claim against Landlord.

     67.  Notwithstanding anything to the contrary in this lease it is agreed
that any demand for rent may be made orally and no written notice of any kind
shall be necessary as a condition precedent to commencement of a non-payment
petition:

     68.  In any action or proceeding brought by Landlord for non-payment of
rent, additional rent and/or holdover, Landlord shall if it is the prevailing
party either by court decision or settlement, be entitled to recover the
reasonable legal fees incurred in the prosecution or defense of such action or
proceeding.

     69.  Tenant waives his right to bring any declaratory judgment or action
with respect to any provision of this Lease or with respect to any notice sent
pursuant to the provisions of this Lease, and expressly agrees not to seek any
injunctive relief which would stay, extend or toll any of the time limitations
of or provisions of this Lease, or any notice sent pursuant thereto.  Any breach
of this paragraph shall constitute a breach of a substantial obligation of this
tenancy and shall be grounds for immediate termination of this Lease.

     In the event Landlord shall default in any obligations of this Lease, the
Tenant's right of action under the terms of this Lease shall be limited to an
action for specific performance and Landlord shall not be liable to Tenant for
any damages arising from said breach.
