                              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
                              determination 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 premise, 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 role 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 of the difference referred to above.

                              demised premises shall be taken or occupied by

                              and agrees to take the same "as is" as of the date
                              hereof and acknowledges that the taking of
                              possession of the demised premises by Tenant shall
                              be conclusive evidence that the said premises 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
<PAGE>

                              completely expresses the agreement between Owner
                              and Tenant and any executory agreement hereunder
                              made shall be ineffective to change, modify,
                              discharge or effect an abandonment of its 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 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 premise hereby demised, subject,
                              nevertheless to the terms and conditions of this
                              lease including, but not limited to Article 31
                              hereof and to the ground lease underlying lease,
                              and: mortgages hereinbefore mentioned.

Failure to Give
Possession:                   24. If Owner is unable to give possession of the
                              Possession: 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 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 provision of
                              this lease except as to the covenant to pay rent.
                              The provisions of this
<PAGE>

                              article are intended to constitute "an express
                              provision to the contrary" within the meaning of
                              Section 223 -a of the New York Rent Property Law.
                              Notwithstanding the foregoing, Owner shall give
                              possession within 90 days after fully executed
                              copy of this lease is exchanged between the
                              parties, subject however, to the obligation of the
                              Tenant to perform, any work it is to perform in a
                              timely manner.

No Waiver:                    15. The failure of Owner or Tenant 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 of any covenant of this lease shall not be
                              deemed a waiver of such 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 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 or 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 an
                              summary proceeding for possession of the premises,
                              Tenant will not interpose any counterclaim of
                              whatever nature or description in any such
                              proceeding including a

Inability to
Perform:                      27. Except as otherwise set forth to the contrary

                              obligation of Tenant to pay rent have under and

                              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

                              or regulation of any department or subdivision
