accept such check for payment without prejudice to the Landlord's right to
recover the balance of such rent or pursue any other remedy in this lease
provided.

the sources from which they are usually obtained for said building, or any cause

              without the Landlord's consent which shall not be unreasonably
              withheld; provided, however, that in the event of any such
              assignment, subletting, or permitted action by the Tenant, the
              Tenant shall continue until the end of the term hereof to be fully

       (o) To permit the Landlord at any time or times to decorate common areas,
       and to make, at its own expense, repairs, alterations, additions and
       improvements, structural or otherwise, in or to said building or any part
       thereof, and during such operations to take into and through said
       premises or any part of the building all materials required and to close
       or temporarily suspend operation of the entrances, doors, corridors,
       elevators or other facilities, Landlord agreeing, however, that it will
       carry out such work in a manner which will cause the Tenant a minimum
       inconvenience and business interruption;

       (p) Not to install any vending machines or food service equipment in the
       demised premises without first obtaining the Landlord's prior written
       approval, which approval shall not be unreasonably withheld; except for

       be interpreted as meaning that the Tenant has any authority or power to
       permit any lien of any nature or description to attach to or be placed
       upon the Landlord's title or interest in the building, the premises, or
       any portion thereof;

       Tenant of any portion of the Lease;

       (u) That acceptance by the Landlord of a lesser sum than the base rent,
       supplemental rent or other fees or charges then due shall not be deemed

       other fees or charges due, nor shall any endorsement or statement on any
       check or any letter accompanying any check or payment as rent or other
       payments be deemed an accord and satisfaction and the Landlord may accept
       such check or payment without prejudice to Landlord's right to recover
       the balance of such installment or pursue any other remedy in this Lease.
       The delivery of keys to any employee thereof shall not operate as a
       termination of this Lease or a surrender of the premises;

       incurred in enforcing any obligation of this Lease which has not been
       complied with;

       (w) That without limitation of anything elsewhere herein contained, the
       Landlord


                                       6
<PAGE>

       may;

              (i) designate and change the name and street address of the
              building; provided, however, that the Landlord shall first give
              reasonable notice thereof to the Tenant;

              (ii) retain and use in appropriate instances keys to all doors
              within and into the premises and to change the locks to the
              premises if the Landlord deems it advisable and provides Tenant
              with reasonable advance notice and keys to such new locks. No lock
              shall be changed by the Tenant without prior written consent of
              the Landlord;

              (iii) enter upon the premises and exercise any and all of the
              Landlord's rights without being deemed guilty of an eviction or
              disturbance of the Tenant's use or possession and without being
              liable in any manner to the Tenant;

       (x) That the Tenant shall not remove any of its fixtures from the
       premises at any time that the Tenant is in default under any of the terms
       of this Lease (except for white boards and bulletin boards);

       (y) In the event the Tenant wishes to provide outside services for the
       demised premises over and above those services to be provided by the
       Landlord as set forth herein, the Tenant shall first obtain the prior
       written approval of the Landlord for the installation and/or utilization
       of such services, which approval shall not be unreasonably withheld or
       delayed. "Outside services" shall include but shall not be limited to
       cleaning and moving services, security services, catering services and
       the like. In the event the Landlord approves the installation and/or
       utilization of such services, such installation and utilization shall be
       at the Tenant's sole cost, risk and expense.

                           ARTICLE VII - SUBORDINATION

       7.01 The Tenant agrees that, at the election of the Landlord, that this
Lease shall be subject and subordinate to the lien of any mortgage which may now
hereafter be placed on, encumber, or affect the real property of which the
premises are a part and to all renewals, modifications, consolidations, and
replacements. When requested to do so by the Landlord, the Tenant agrees to
execute, acknowledge, and deliver to the Landlord an instrument, in proper form
for recording, wherein the Tenant agrees to and does subordinate this Lease to
the lien of the mortgages above mentioned.

       The Landlord agrees to use its best efforts to promptly obtain from each
and every mortgagee of the premises a non-disturbance agreement whereby the
mortgagee shall agree that, should the mortgagee assume the management
responsibility for the premises, the mortgagee will permit the Tenant to
continue to operate under this Lease.

                ARTICLE VIII - CASUALTY DAMAGE AND EMINENT DOMAIN

       8.01 If at any time during the lease term the premises shall be damaged
or destroyed by


                                       7
<PAGE>

fire or other casualty, then the Landlord shall have the election to terminate
this Lease or to repair and reconstruct the premises to the condition thereof
immediately prior to such damage or destruction. Unless such fire or other
casualty shall have been caused by the negligence of the Tenant, its agents,
employees, or invites, rent shall abate proportionately during the period and to
the extent that the premises are unfit for the use by the Tenant in the ordinary
conduct of its permitted uses hereunder. If the Landlord has elected to repair
and restore the premises, this Lease shall continue in full force and effect and

Lease, then the terms of this Lease including all provisions for rent and other

holdover provision shall not preclude the Landlord from recovering any other
damages which it incurs as a result of Tenant's failure to vacate the premises
at the termination of this Lease.
