executors, administrators, legal representatives, successors and
assigns, hereby covenant as follows:

prompt notice of any defective condition in the premises for which Owner
may be responsible hereunder. 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 others making repairs, alterations, additions or improvements
in or to any portion of the building or the demised premises or in and to
the fixtures, appurtenances or equipment thereof. It is specifically
agreed that Tenant shall not be entitled to any setoff or reduction of

or body having or asserting jurisdiction.

Requirements of Law, Fire Insurance, Floor Loads:

any similar body which shall impose any violation, order or duty upon
Owner or Tenant with respect to the demised premises, whether or not
arising out of Tenant's use or manner of use thereof, (including
Tenant's permitted use) or, with respect to the building if arising out
of Tenant's



use or manner of use of the premises or the building (including the use
permitted under the lease). Nothing herein shall require Tenant to make
structural repairs or alternations unless Tenant has, by its manner of use of
the demised premises or method of operation therein, violated any such laws,
ordinances, orders, rules, regulations or requirements with respect thereto.
Tenant may, after securing Owner to Owner's satisfaction against all damages,
interest, penalties and expenses, including, but no limited to, reasonable
attorney's fees, by cash deposit or by surety bond in an amount and in a
company satisfactory to Owner, contest and appeal any such laws, ordinances,
orders, rules, regulations or requirements with respect thereto. Tenant may,
after securing Owner to Owner's satisfaction against all damages, interest,
penalties and expenses, including, but not limited to, reasonable attorney
fee's, by cash deposit or by surety bond in any amount and in a company
satisfactory to Owner, contest and appeal any such laws, ordinances, orders,
rules, regulations or requirements provided same is done with all reasonable
promptness and provided such appeal shall not subject Owner to prosecution
for a criminal offense or constitute a default under any lease or mortgage
under which Owner may be obligated, or cause the demised premises or any part
thereof to be condemned to vacated. Tenant shall not do or permit any act or
thing to be done in or to the demised premises which is contrary to law, or

form a part, or which shall or might subject owner to any liability or
responsibility to any person or for property damage. Tenant shall not keep
anything in the demised premises except as now or hereafter permitted by the
Fire Department, Board of Fire Underwriters, Fire Insurance Rating

manner and such quantity so as not to increase the rate for fire insurance
applicable to the building, or use the premises in a manner which increase
that insurance rate for the building or any property located therein over
that in effect prior to the commencement of Tenant's occupancy. Tenant shall
pay all costs, expenses, fines, penalties, or damages, which may be imposed
upon Owner by reason of Tenant's failure to comply with the provisions of
this article and if by reason of such failure the fire insurance rate shall,
at the beginning of this lease or at any time thereafter, by additional rent
hereunder, for the portion of all fire insurance premiums thereafter paid by
Owner which shall be been charged because of such failure by Tenant. In any
action or proceeding wherein Owner and Tenant are parties, a schedule or
"make-up" of rate for the building or demised premises issued by the New York
Fire Insurance Exchange, or other body making fire insurance rates applicable
to said premises shall be conclusive evidence of the facts therein stated and
of the several items and charges in the fire insurance rates then applicable
to said premises. Tenant shall not place load upon any floor of the demised
premises exceeding the floor load per square foot area which it was designed
to carry and which is allowed by law. Owner reserves the right to prescribe
the weight and position of all safes, business machines and mechanical
equipment. Such installations shall be placed and maintained by Tenant, at
Tenant's expense, in settings sufficient, in Owner's judgement, to absorb and
prevent vibration, noise and annoyance.

extensions of any such underlying leases and mortgages. This clause shall be
self-operative and no further instrument of subordination shall be required
by any ground or underlying lessor or by any mortgagee, affecting any lease
or the real property of which the demised premises are a part. In
confirmation of such subordination, Tenant shall execute promptly any
certificate that Owner may request.

8.  Owner or its agents shall not be liable for any damage to property of
Tenant or of others entrusted to employees of the building, nor for loss of

nature, unless cause by or due to the negligence of Owner, its agents,
servants or employees. Owner or its agents will not be liable for any such
damage caused by other tenants or persons in, upon or about said building or
caused by operations in construction of any private, public or quasi-public

or incurred as a result of any breach by Tenant, Tenant's agents,

forth. (b) If the demised premises are partially damaged or rendered
partially unusable by fire or other casualty, the damages thereto shall be

be substantially completed, shall be apportioned from the day following the
casualty according to the part of the premises which is usable. (c) If the
demised premises are totally damaged or rendered wholly unusable by fire or
other casualty, then the rent shall be proportionately paid up to the time of

this lease shall expire as fully and completely as if such date were the date
set forth above for the termination of this lease and Tenant shall forthwith
quit, surrender and vacate the premises without prejudice however, to
Landlord's rights and remedies against Tenant under the lease provisions in
effect prior to such termination, and any rent owning shall be paid up to
such date and any payments of rent made by Tenant which were on account of
any period subsequent to such date shall be returned to Tenant. Unless Owner
shall serve a termination notice as provided for herein, Owner shall make the
repairs and restorations under the conditions of (b) and (c) hereof, with all
reasonable expedition, subject to delays due to adjustment of insurance
claims, labor troubles and causes beyond Owner's control. After any such
casualty, Tenant shall cooperate with Owner's restoration by removing from
the premises as promptly as reasonably possible, all of Tenant's salvageable
inventory and movable equipment, furniture, and other property. Tenant's
liability for rent shall resume five (5) days after written notice from
Owner hat the premises are substantially ready for Tenant's occupancy. (e)
Nothing contained hereinabove shall relieve Tenant from liability that may
exist as a result of damage from fire or other insurance in its favor before
making any claim against the other party for recovery for loss or damage
resulting from fire or casualty, and to the extent that such insurance is in
force and collectively and to the extent permitted by law, Owner and Tenant
each hereby releases and waives all right of recovery against the other or
any one claiming through or under each of them by way or subrogation or
otherwise. The foregoing release and waiver shall be in force only if both
releasors' insurance policies contain a clause providing that such a release
or waiver shall not invalidate the insurance. If, and to the extent, that
such waiver can be obtained only by the payment of additional premiums, then
the party benefitting from the waiver shall pay such premium within ten days
after written demand or shall be deemed to have agreed that the party
obtaining insurance overage shall be free of any further obligation under the
provisions hereof with respect to waiver of subrogation. Tenant acknowledges
that Owner will carry insurance on Tenant's furniture and/or furnishings or
any fixtures or equipment, improvements, or appurtenances removable by Tenant
and agrees that Owner will not be obligated to repair any damage thereto or
replace the same. (f) Tenant hereby waives the provisions of Section 227 of
the Real Property Law and agrees that the provisions of this article shall
govern and control in lieu thereof.

legal representatives, successors and assigns, expressly covenants that it
shall not assign, mortgage or encumber this agreement, nor underlet, or
others, without the prior written consent of Owner in each instance. Transfer
of the majority of the stock of corporate Tenant shall be deemed an
assignment. If this lease be assigned, or if the demised premises or any party
thereof be underlet or occupied by anybody other than the Tenant, Owner may,
after default by Tenant, collect rent from the assignee, under-tenant or
occupant as tenant or a release of Tenant from the further performance by
Tenant of covenants on the part of Tenant herein contained. The consent by
Owner to an assignment or underletting shall not in any wise be construed to
relieve Tenant from obtaining the express consent in writing of Owner to any
further assignment or underletting.

Electric Current:

12. Rates and conditions in respect to submetering or rent inclusion, as the
case may be, to be added in RIDER attached hereto. Tenant covenants and
agrees that at all times its use of electric current shall not exceed the
capacity of existing feeders to the building or the risers or wiring
installation and Tenant may not use an electrical equipment which, in
Owner's opinion, reasonably exercised, will overload such installations or
interfere with the use thereof by other tenants of the building. The change
at any time of the character of electric service shall in no wise make Owner
liable or responsible to Tenant, for any loss, damages or expenses which
Tenant may sustain.

Access to Premises:

13. Owner or Owner's agents shall have the right (but shall not be obligated)
to enter the demised premises in any emergency at any time, and, at other
reasonable times, to examine the same and to make such repairs, replacements
and improvements and Owner may elect to perform. Tenant shall permit Owner to
use and maintain and replace pipes and conduits in and through the demised

last six months of the term for the purpose of showing the same to
prospective tenants. If Tenant is not present to open and permit an entry
into the premises, Owner or Owner's agents may enter the same whenever such
entry may be necessary or permissible by master key or forcibly  and provided
reasonable care is exercised to safeguard Tenant's property, such entry shall
not render Owner or its agents liable therefor, nor in any event shall the
obligations of Tenant hereunder be affected. If during the last month of the
term Tenant shall have removed all or substantially all of Tenant's property
therefrom Owner may immediately enter, alter, renovate or redecorate the
demised premises without limitation or abatement of rent, or incurring

14.  No Vaults, vault space or area, whether or not enclosed or covered, not
within the property line of the building is leased hereunder, anything
contained in or indicated on any sketch, blue print or plan, or anything

building. All vaults and vault space and all such areas not within the
property line of the building, which Tenant may be permitted to use and/or
occupy, is to be used and/or occupied under a revocable license, and if any
such license be revoked, or if the amount of such space or area be diminished
or required by any federal, state or municipal authority or public utility,

any compensation or dimution or abatement of rent, nor shall such revocation,
dimution or requisition be deemed constructive or actual eviction. Any tax,
fee or charge of municipal authorities for such vault or area shall be paid
by Tenant.

OCCUPANCY:

violation o the certificate of occupancy issued for the building of which the

work, if any. In any event, Owner makes no representation as to the condition
of the premises and Tenant agrees to accept the same subject to violations,
whether or not of record.

BANKRUPTCY:

16. (a) Anything elsewhere in this lease to the contrary notwithstanding,
this lease may be cancelled by Owner by the sending of a written notice to
Tenant within a reasonable time after the happening of any one or more of the
following events: (1) the commencement of a case in bankruptcy or under the
laws of any state naming Tenant as the debtor; or (2) the making by Tenant of
an assignment or any other arrangement for the benefit of creditors under any
state statute. Neither Tenant nor any person claiming through or under
Tenant, or by reason of any statute or order of court, shall thereafter be
entitled to possession of the premises demised but shall forthwith quit and
surrender the premises. If this lease shall be assigned in accordance with
its terms, the provisions of this Article 16 shall be applicable only to the
party then owning Tenant's Interest in this lease.

    (b) it is stipulated and agreed that in the event of the termination of
this lease pursuant to (a) hereof, Owner shall forthwith, notwithstanding any
other provisions of this lease to the contrary, be entitled to recover from
Tenant as and for liquidated damages an amount equal to the difference
between the rent reserved hereunder for the unexpired portion of the term
demised and 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 be relet by the Owner for the unexpired term of said
lease, 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, ad 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 of the difference referred to above.

DEFAULT:

17. (1) If Tenant defaults in fulfilling any of the covenants of this lease
other than the covenants for the payment of rent or additional rent; or if
the demised premises become vacant or deserted; or if any execution or
attachment shall be issued against Tenant or any of Tenant's property
whereupon the demised premises shall be taken or occupied by someone other
than Tenant; or if this lease be rejected under Section 235 of Title 11 of
the U.S. Code (bankruptcy code); or if Tenant shall fail to move into or take
possession of the premises within fifteen (15) days after the commencement of
the term of this lease, then, if any one or more of such events, upon Owner
serving a written five (5) days notice upon Tenant specifying the nature of
said default and upon the expiration of said five (5) days notice upon Tenant
specifying the nature of said default and upon the expiration of said (5)
days, if Tenant shall have failed to comply with or remedy such default, or
if the said default or omission complained of shall be of a nature that the
same cannot be completely cured or remedied within said five (5) day period,
and if Tenant shall not have diligently commenced curing such default within
such five (5) day period, and shall not thereafter with reasonable diligence
and in good faith, proceed to remedy or cure such default, then Owner may
serve a written three (3) days' notice of cancellation of this lease upon
Tenant, and upon the expiration of said three (3) days this lease and the
term thereunder shall end and expire as fully and completely as if the
expiration of such three (3) day period were the day herein definitely fixed
for the end and expiration of this lease and the term thereof and Tenant
shall then quit and surrender the demised premises to Owner but Tenant shall
remain liable as hereinafter provided.

    (2) If the notice provided for in (1) hereof shall have been given, and
the term shall expire as aforesaid; or if Tenant shall make default in the
payment of the rent reserved herein or any item of additional rent herein
mentioned or any part of either or in making any other payment herein
required then and in any of such events Owner may without notice, re-enter
the demised premises either by force or otherwise, and dispossess Tenant by
summary proceedings or otherwise, and the legal representative of Tenant or
other occupant of demised premises and remove their effects and hold the
premises as if this lease had not been made, and Tenant hereby waives the
service of notice of intention to re-enter or to institute legal proceedings
to the end. If Tenant shall make default hereunder prior to the date fixed as
the commencement of any renewal or extension of this lease, Owner may cancel
and terminate such renewal or extension agreement by written notice.

REMEDIES OF OWNER AND WAIVER OF REDEMPTION:

18. In case of any such default, re-entry, expiration and/or dispossess by
summary proceedings or otherwise, (a) the rent shall become due thereupon and
be paid up to the time of such re-entry, dispossess and/or expiration, (b)
Owner may re-let the premises or any part or parts thereof, either in the
name of Owner or otherwise for a term or terms, which may at Owner's option
be less than or exceed the period which would otherwise have constituted the
balance of the term of this lease and may grant concessions or free rent or
charge a higher rental than that in this lease, and/or (c) Tenant or the
legal representatives of 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 constituted the balance of the term of this
lease. The failure of Owner to re-let the premises or any part or parts
thereof shall not release or affect Tenant's liability for damages. In
computing such liquidated damages there shall be added to the said deficiency
such expenses as Owner may incur in connection with re-letting, such as legal
expenses, attorney's fees, brokerage, advertising and for keeping the demised
premises in good order or for preparing the same for re-letting. Any such
liquidated damages shall be paid in monthly installments by Tenant on the
rent day specified in this lease and any suit brought to collect the amount
of the deficient for any months shall not prejudice in any way the rights of
Owner to collect the deficiency for any subsequent month by a similar
proceeding. Owner, in putting the demised premises in good order or preparing
the same for re-rental may, at Owner's option, make such alterations,
repairs, replacements, and/or decorations in the demised premises as Owner,
in Owner's sole judgement, considers advisable and necessary for the purpose
of re-letting the demised premises, and the making of such alterations,
repairs, replacements, and/or decorations shall not operate or be construed
to release Tenant from liability hereunder as aforesaid. Owner shall in no
event be liable in any way whoever for failure to re-let the demised
premises, or in the event that the demised premises are re-let, for failure
to collect the rent thereof under such re-letting, and in no even shall
Tenant be entitled to receive any excess, if any, of such net rents collected
over the sums payable by Tenant to Owner hereunder. In the event of a breach
or threatened breach by Tenant of any of the covenants or provisions hereof,
Owner shall have the right of injunction and the right to invoke any remedy
allowed at law or in equity as if re-entry, summary proceedings and other
remedies were not herein provided for. Mention in this lease of any
particular remedy, shall not preclude Owner 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 the event of Owner
obtaining possession of demised premises, by reason of the violation by
Tenant of any of the covenants and conditions of this lease, or otherwise.

FEES AND EXPENSES:

19. If Tenant shall default in the observance or performance of any term or
covenant on Tenant's part to be observed or performed under or by virtue of
any of the terms or provisions in any article of this lease, then, unless
otherwise provided elsewhere in this lease, Owner may immediately or at any
time thereafter and without notice perform the obligation of Tenant
thereunder. If Owner, in connection with the foregoing or in connection with
any default by 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, 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 therefor. 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 AND MANAGEMENT:

20. Owner shall have the right at any time without the same constituting an
eviction and without incurring liability to Tenant therefor 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 REPRESENTATIONS 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, ???, 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 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
will be a legal holiday which case it will 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 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 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 the 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 of 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 of any covenant of this
lease shall not be deemed a waiver of such breach and no such provision of
this lease shall be deemed to have been waiver 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 of 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 of counter-claim 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 the 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 doing so by reason of
strike or labor troubles or any cause whatsoever including, but no limited
to, government preemption in connection with a National Emergency or by
reason of any rule, order or regulation of any department or subdivision
thereof of any government agency or by reason of the conditions of supply and
demand which have been or are affected by war or other emergency.

Bills and Notices:

28. Except as otherwise in this lease provided, a bill, statement, notice or
communications which Owner may desire or be required to give to Tenant, shall
be deemed sufficiently given or rendered if, in writing, delivered to Tenant
personally or sent by registered or certified mail addressed to Tenant at the
building of which the demised premises form a part or at the last known
residence address of business address of Tenant, and the time of the rendition
of such bill or statement and of the giving of such notice or communication
shall be deemed to be the time when the same is delivered to Tenant, mailed,
or left at the premises as herein provided. Any notice by Tenant to Owner
must be served by registered or certified mail addressed to Owner at the
address first hereinabove given or at such other address as Owner shall
designate by written notice.

Services Provided by Others:

29. As long as Tenant is not in default under any of the covenants of this
lease, Owner shall provide: (a) necessary elevator facilities on business
days from 8 a.m. to 6 p.m. and on Saturdays from 8 a.m. to 1 p.m. and have
one elevator subject to call at all other times; (b) heat to the demised
premises when and as required by law, on business days from 8 a.m. to 6 p.m.
and on Saturdays from 8 a.m. to 1 p.m.; (c) water for ordinary lavatory
purposes, but if Tenant uses or consumes water for any other purposes or in
unusual quantities (of which fact Owner shall be the sole judge). Owner may
install a water meter at Tenant's expense which order and repair to register
such water consumption and Tenant shall pay for water consumed as shown on
said meter as additional rent as and when bills are rendered; the premises
are to be kept clean by Tenant, which shall be done at Tenant's sole expense,
in a manner satisfactory to Owner and no one other than persons approved by
Owner shall be permitted to enter said premises of the building of which
they are a part for such purpose. Tenant shall pay Owner the cost of removal
of any of Tenant's refuse and rubbish from the building; Owner reserves the
right to stop services of the heating, elevators, plumbing, power systems or
other services, if any, when necessary by reason of accident or for repairs,
alterations, replacements or improvements necessary or desirable in the
judgement of Owner for as long as may be reasonably required by reason
thereof. If the building of which the demised premises are a part supplies
manually-operated elevator service, Owner at any time may substitute
automatic-controlled elevator service and upon ten days' written notice to
Tenant, proceed with alterations necessary therefor without in any wise
affecting this lease or the obligation of Tenant hereunder. The same shall be
done with a minimum of inconvenience to Tenant and Owner shall pursue the
alteration with due diligence.

security to a new Owner. Tenant forth covenants that it will not assign or

assignment or attempted encumbrance.
