               THIS AGREEMENT, made as of the 10th day of January, 1995, by
     and between THE PORT AUTHORITY OF NEW YORK AND NEW JERSEY (hereinafter

               WITNESSETH, That:

               The Port Authority and the  Lessee, for and in consideration
     of the rents, covenants and agreements hereinafter contained, mutually
     covenant and agree as follows:


     Section 1.     Letting

               The  Port Authority hereby lets to the Lessee and the Lessee

     with  the  fixtures,  improvements  and other  property  of  the  Port
     Authority located or to be  located therein or thereon, and the  space
     as shown in  diagonal hatching on  the sketch annexed  hereto, made  a
     part hereof  and marked  "Exhibit A-1",  together  with the  fixtures,
     improvements and other property of the Port Authority located or to be
     located  therein or  thereon, the  spaces, fixtures,  improvements and
     other property of the Port Authority shown on Exhibit A and Exhibit A-
     1 being hereinafter collectively  referred to as the "premises".   The
     Port Authority and  the Lessee hereby  acknowledge that the  aforesaid
     premises constitutes non-residential real property.

     Section 2.     Term

               (a)  The  term of  the letting  of the  premises under  this
     Agreement shall commence at  12:01 o'clock A.M. on the  earlier of the
     following dates:  (i) the two hundred fourteenth (214th) day following
     the Prior Entry Date, as such term is defined in paragraph (c) of this
     Section, or (ii) such date as the Lessee commences business operations
     in the premises.  The term  of the letting shall expire, unless sooner
     terminated,  or unless  extended, at  11:59 o'clock  P.M., on  the day
     preceding the  fifteenth (15th)  anniversary of the  Rent Commencement
     Date,  as  such  term is  defined  in  the Section  of  this Agreement
     entitled "Basic Rental".

                    (b)  If  on  March  22,   1995  the  premises  are  not
     available or ready for  the commencement therein by the  Lessee of its
     proposed construction and finishing work pursuant to and in accordance
     with  the  provisions  of  the  Section  of  this  Agreement  entitled
     "Lessee's  Finishing Work"  by  reason  of  the  fact  that  the  Port
     Authority  has  not  then  completed  those  provisions  of  the "Port

                                        1


     Authority  Work", as  such  term is  defined in  the  Section of  this
     Agreement entitled  "Port Authority  Work", which  are required  to be
     completed  on or  prior to  the  Prior Entry  Date or  by reason  of a
     casualty  of the  type  described in  the  Section of  this  Agreement
     entitled "Casualty",  then the Port  Authority may postpone  the Prior
     Entry  Date  for the  premises and  the  Port Authority  shall  not be
     subject  to any  liability for  such postponement  or failure  to give
     possession  of the  premises  on  such  date  except  as  provided  in
     paragraph  (d) below.    No  such  postponement  or  failure  to  give
     possession of the premises on March 22, 1995 shall affect the validity
     of  this  Agreement  or  the  obligations  of  the  Lessee  hereunder.
     However, in  such event, the  Prior Entry  Date shall not  occur until
     possession  thereof is tendered by  the Port Authority  to the Lessee;
     tender shall be made by  notice given at least five (5) days  prior to
     the effective date of the tender.   In the event that notice of tender
     of the premises is not given for possession thereof to  commence on or
     prior to  March 21, 1996 for  the reasons set forth  in this paragraph
     (b), then  the letting of the  premises under this Agreement  shall be
     deemed  cancelled, and each party does release and discharge the other
     from any and all claims and demands  in any way related to the letting
     of the premises based on this Agreement, or a breach or alleged breach
     thereof.  

                    (c)  For purposes of this Agreement "Prior  Entry Date"
     shall  mean March 22, 1995, as such  date may be postponed pursuant to
     the  provisions of paragraph  (b) above of  this Section.   The Lessee
     shall be permitted entry into the premises on the Prior Entry Date for
     the  purpose of performing its  construction and installation work and
     the Lessee's use of the premises during the period commencing with the
     Prior   Entry  Date  and  continuing  up  to  the  day  preceding  the
     commencement  date of the term of the  letting shall be subject to and
     in  accordance with  all the  terms and  conditions of  this Agreement
     except those relating to payment of rental and rights of user.

                    (d)  In the  event that the  Prior Entry Date  does not
     occur on or before April 1, 1995 due to the Port Authority's inability
     to complete those  portions of the Port Authority  Work which the Port
     Authority has agreed to complete  prior to the Prior Entry  Date, then
     the  two hundred seventy-one  (271) day  period from  the commencement
     date  of  the  term  of  the   letting  used  to  determine  the  Rent
     Commencement Date shall be increased by the sum of the following:  (i)
     one (1) day for each of the first sixty (60) excess days plus (ii) one
     and three quarter  days (1 ) for  each excess day,  if any, after  the
     first  sixty (60)  excess days.   For  purposes of this  paragraph (d)
     "excess days"  shall be the  number of  days in the  period commencing
     April 2, 1995  and ending on  the day preceding  the Prior Entry  Date
     less the number of days in  the period subsequent to execution of this
     Agreement  by  the  parties hereto  that  the  Port  Authority or  its
     contractor  is prevented  from performing such  portions of  such Port
     Authority Work by forces and conditions beyond the control of the Port
     Authority.

     Section 3.     Rights of User by the Lessee

                    The  Lessee shall  use the  premises for  the following
     purposes only and purposes incidental thereto and for no other purpose
     whatsoever:  as clerical, executive and administrative offices for the
     Lessee's business of providing reinsurance services to firms providing

                                        2


     insurance services to entities engaged in world trade and commerce and
     such  other  type or  types of  business or  operations engaged  in or
     previously engaged by other  office tenants at the World  Trade Center
     whose  eligibility  and  qualifications  are determined  by  the  Port
     Authority  under the  provisions  of  Chapter 5  of  Title 17  of  the
     Unconsolidated Law of the State  of New York strictly on the  basis of
     their functions, activities and services in  world trade and commerce.
     In the event the Port Authority transfers fee title to the World Trade
     Center or to the building  in which the premises are located  to other
     than a governmental or quasi governmental entity, then notwithstanding
     the foregoing  sentence the  Lessee from  and effective  the effective
     date of such transfer may use the premises for general office purposes
     consistent with the operation of a first class office building.

                         (iii)During  the  period from  and after
               the  tenth   (10th)   anniversary  of   the   Rent
               Commencement  Date through the balance of the term
               of the  letting under this Agreement,  at the rate

                                        3


               through  the balance  of the  term of  the letting
               under this Agreement.

                    (b)  If the Rent Commencement  Date shall be other than
     the  first day  of a calendar  month, the installment  of basic rental
     payable  on the  Rent Commencement  Date shall  be the  amount  of the
     monthly installment stated  in subparagraph (a)(i),  above, multiplied
     by  a fraction the numerator of which shall  be the number of days the
     letting  was in  effect  in  the  calendar month  in  which  the  Rent
     Commencement  Date  fell and  the denominator  of  which shall  be the
     number  of  days in  that  calendar  month and  if  the expiration  or
     termination date of the letting is other than the last day of a month,
     the basic rental for the portion of the month during which the letting
     is effective shall be the amount of the applicable monthly installment
     similarly prorated.  If  any basic rental  increase is effective on  a
     day other  than the  first  day of  a calendar  month  there shall  be
     payable in advance  on the  effective date of  the rental increase  an
     installment  of  rental equal  to  one-twelfth  of  the annual  rental
     increase multiplied by a fraction, the numerator of which shall be the
     number of days  from and including  the effective date  of the  rental
     increase to  the end of  the month  in which the  rental increase  was
     effective and the denominator of which shall be the number  of days in
     that month.

                    (c)  For  purposes of this Agreement "Rent Commencement
     Date" shall mean the  two hundred seventy  first (271st) day from  the
     commencement  date of  the term  of the  letting  as such  two hundred
     seventy-one (271) day  period may  be increased by  the provisions  of
     paragraph (d) of the Section of this Agreement entitled "Term" and the
     provisions of the Section of this Agreement  entitled "Construction by
     the Lessee".

                    (d)  The basic rental for  the premises set forth above
     in this Section shall be subject to adjustment during the  term of the
     letting  of the premises in accordance with the provisions of Schedule
     A attached to this Agreement and hereby made a part hereof.

     having  jurisdiction over the operations of the Lessee at the premises
     or at the World Trade Center which may be necessary for the conduct of
     its  operations.  The Lessee  shall promptly observe,  comply with and
     execute  the provisions of any and all present and future governmental
     laws, rules and regulations, requirements, orders and directions which
     may pertain or  apply to the operations of the  Lessee on the premises

     subject  to the provisions of  the Section of  this Agreement entitled
     "Construction  by   the  Lessee",  make  any   and  all  improvements,
     alterations or repairs  of the premises  that may be  required at  any
     time  hereafter by any such  present or future  law, rule, regulation,
     requirement,   order   or  direction,   provided   such  improvements,
     alterations  or  repairs are  not  required  generally throughout  the
     building  in  which  the  premises  are  located unless  such  general
     requirement results from the  Lessee's particular manner of use  of or

                                        4


     its  particular operations  in the  premises which  are not  common to
     other tenants in the building in  which the premises are located.  The
     provisions of  this Section are not to be construed as a submission by
     the  Port Authority to the application to itself of such requirements,
     or any of them.


     Section 6.     Rules and Regulations

                    The  Lessee covenants  and agrees  to observe  and obey
     (and   to   compel   its   officers,   members,   employees,   agents,
     representatives,  contractors, customers,  guests, invitees  and those
     doing business with it to observe and  obey) the Rules and Regulations
     of the Port Authority (a copy of which is attached hereto, hereby made
     a part  hereof  and marked  "Exhibit  R") for  the  government of  the
     conduct  and  operations of  the Lessee,  and such  further reasonable
     rules  and regulations (including  amendments and supplements thereto)
     as may  from time to time and throughout the letting be promulgated by
     the  Port Authority for reasons  of safety, health  or preservation of
     property, or for the maintenance of the good and orderly appearance of
     the premises and the World  Trade Center or for the safe  or efficient
     operation of the World  Trade Center, provided, however, that  in case
     of  any  conflict  or inconsistency  between  the  provisions  of this
     Agreement and any of the Rules and Regulations, the provisions of this
     Agreement  shall control.  The  Port Authority agrees  that, except in
     cases of  emergency, it will give  notice to the Lessee  of every such
     further rule  or regulation adopted by  it at least  fifteen (15) days
     before the Lessee  shall be  required to comply  therewith.  The  Port
     Authority shall not  enforce any of the Rules and  Regulations in such
     manner as to discriminate against the Lessee.

     Section 7.     Responsibilities of the Lessee

                    (a)    The Lessee  shall conduct  its operations  in an
     orderly  and proper  manner and  so  as not  to annoy,  disturb or  be
     offensive to  others at the  World Trade Center, and  the Lessee shall
     control  the  conduct of  its  officers,  members, employees,  agents,
     representatives,  contractors, customers,  guests, invitees  and those
     doing  business with  it.   Upon  objection  from the  Port  Authority
     concerning the conduct of  any such the Lessee shall  immediately take
     all steps necessary to cure or remove the cause of the objection.

                    (b)  The Lessee shall not knowingly commit or knowingly
     continue any  nuisance on  the premises,  or do or  permit to  be done
     anything which may result in the  creation or commission of a nuisance
     on the premises, and the Lessee shall not knowingly cause or knowingly
     permit or  continue to be  caused or  produced upon  the premises,  to
     permeate the same  or to  emanate therefrom, any  unusual, noxious  or
     objectionable smokes, gases, vapors, odors or objectionable noises.

                    (c)   The Lessee shall not use or connect any equipment
     or  engage in any  activity or  operation in  the premises  which will
     cause or tend to cause an  overloading of the capacity of any existing
     or  future utility,  mechanical,  electrical, communication  or  other
     systems,  or  portion thereof,  serving  the premises,  nor  shall the
     Lessee do or  permit to be done anything which  may interfere with the
     effectiveness  or  accessibility  of  existing   and  future  utility,
     mechanical,  electrical, communication  or other  systems  or portions

                                        5


     thereof  on the  premises  or elsewhere  at  the World  Trade  Center.
     Nothing  in  this  paragraph (c)  shall  be  construed  to impose  any
     liability  on the  Lessee for  unknowingly overloading  the electrical
     system,  which  such overloading  results  from  the Port  Authority's
     failure to  supply electricity  in accordance with  the specifications
     set forth in Schedule D.

                    (d)  The Lessee shall not overload any  floor, roadway,
     passageway, pavement or  other surface or any wall,  partition, column
     or  other supporting member, or  any elevator or  other conveyance, in
     the premises  or at  the World Trade  Center and without  limiting any
     other provision of this Agreement, the Lessee shall repair, replace or
     rebuild  any such damaged by  overloading.  The  Port Authority hereby
     represents  that the  floor  load for  the  premises is  as stated  in
     Schedule D, attached hereto and hereby made a part hereof.  Subject to
     the provisions of the Section of this Agreement entitled "Construction
     by the  Lessee", the Lessee  at its cost  and expense may  perform the
     work necessary to reinforce the existing floor load in the premises.

                    (e)   Except as hereinafter provided  in this paragraph
     (e), the Lessee shall  not install, maintain or operate  or permit the
     installation, maintenance or operation on the premises of any  vending
     machine  or service  designed  to dispense  or  sell food,  beverages,
     tobacco products or merchandise  of any kind, whether or  not included
     in the above categories, or any  restaurant, cafeteria, kitchen, stand
     or  other establishment  for  the preparation,  dispensing or  sale of
     food,  beverages, tobacco or  tobacco products, or  merchandise of any
     kind or any equipment or device for  the furnishing to the public of a
     service  of  any  kind,   including  without  limitation  thereto  any
     telephone  pay-stations.  Subject to  all the terms  and provisions of
     this Agreement,  and notwithstanding  the provisions of  the preceding
     sentence of this paragraph (e) and  Rule 20, the Lessee may install an
     eating facility in  the premises pursuant to  an approved construction
     application  as  provided in  the Section  of this  Agreement entitled
     "Construction by the Lessee" and may operate such eating facility with
     its  own employees,  or  arrange  for  the  operation  thereof  by  an
     independent  contractor or operator selected  by the Lessee unless the
     Port  Authority  reasonably determines  that  the  said contractor  or
     operator  will adversely affect  or interfere  with operations  at the
     Facility or will cause or contribute  to the causing of labor problems
     or  disturbances thereat,  and the  Lessee may  install food  and non-
     alcoholic beverage  vending machines  or arrange for  the installation
     and  operation  of  such machines,  subject  to  the Port  Authority's
     reasonable approval  of the type  and method of  installation thereof,
     and the Lessee may use an independent contractor, operator or supplier
     for such machines  selected by  the Lessee unless  the Port  Authority
     reasonably determines that said  contractor, operator or supplier will
     adversely  affect or interfere with operations at the Facility or will
     cause or contribute to  the causing of labor problems  or disturbances
     thereat, provided that such eating facility and vending machines shall
     be installed and  operated solely  for use by  the Lessee's  officers,
     members, employees, contractors, customers, guests, and invitees.  The
     Lessee's agreement with any contractor, operator or supplier of eating
     facilities or vending machines shall permit cancellation by the Lessee
     on  short term  notice in  the event  the Port Authority  notifies the
     Lessee  that such contractor, operator  or supplier fails  to meet the
     standards  described  in this  paragraph.   In  the event  any  of the
     aforesaid installations  shall require modifications or alterations to

                                        6


     building systems or equipment  (including heating, ventilating or air-
     conditioning systems),  and whether such modifications or installation
     thereof are  performed by the  Lessee or  by the  Port Authority,  the
     Lessee shall be responsible for the cost of any such modifications  or
     alterations, and no such alteration or modification shall be commenced
     until  the Lessee  has received  an approved  construction application
     therefor.  The Port Authority reserves the right from time  to time to
     make  additional  reasonable charges  to the  Lessee  for any  and all
     utilities or  other  building services  used  in connection  with  any
     eating facilities or  any of the aforesaid machines, provided, however
     that  the provisions  of  this sentence  shall  not be  applicable  to
     utilities  and  building  services  for  which  a  charge  or  fee  is
     specifically  provided  for  in  this  Agreement  or  for  which  this
     Agreement specifically states  that there  will be no  charge or  fee.
     The Lessee covenants and  agrees that upon notification from  the Port
     Authority that objectionable  odors emanate from  the premises as  the
     result  of  the operation  of any  eating  facility equipment  or food
     vending  machines  in  the  premises  (whether  through  the  building
     heating, ventilating  or air-conditioning systems  or otherwise),  the
     Lessee will  immediately take  all necessary  steps to  eliminate such
     odors, or  if such  odors cannot  be  so eliminated,  the Lessee  will
     discontinue use of such  eating facility or food vending  machines and
     shall  not resume the use  or operation thereof  until written consent
     therefor  has been obtained from  the Port Authority.   Nothing herein
     shall be deemed to permit the operation on the premises  of any public
     food or other merchandise or vending operation or service of any kind.

                    (f)  The Lessee shall not use or make any reference, by
     advertising or otherwise, to the names "World Trade Center" (except to
     designate   the  Lessee's  business   address  and  then   only  in  a
     conventional manner  and without  emphasis  or display  and except  in
     connection with any contemplated  subletting or assignment), "The Port
     Authority  of  New  York and  New  Jersey",  "Port  Authority" or  any
     simulation or abbreviation of  any such names, or any  emblem, picture
     or reproduction of the World Trade Center, for any purpose whatsoever.
     Upon notice  from  the Port  Authority  the Lessee  shall  immediately
     discontinue any such use or reference.

                    (g)  The Lessee recognizes that the  Port Authority has
     undertaken the planning, construction and operation of the World Trade
     Center as a facility of commerce pursuant to concurrent legislation of
     the  State of New  York, Chapter 209,  Laws of New  York, 1962 and the
     State  of  New Jersey,  Chapter  8, Laws  of  New Jersey,  1962.   The
     purpose, character and scope of the Lessee's occupancy,  operation and
     usage of  the premises as described  in the Section of  this Agreement
     entitled "Rights of User by the Lessee"  are of primary importance and
     inducement  to the Port Authority  in entering into  this Agreement of
     lease  with  the  Lessee.   The  Lessee has  represented  to  the Port
     Authority that all its occupancy, operation and usage, throughout  the
     term  of the letting hereunder, will be  in strict accordance with and
     subject  to the  provisions and  requirements of  the Section  of this
     Agreement  entitled  "Rights  of User  by  the  Lessee"  and the  Port
     Authority has  relied on such  representations in  entering into  this
     Agreement.  Without affecting the Lessee's liability for any breach of
     this  representation and its obligations  hereunder, in the event that
     the Lessee has not complied with  all the requirements of this Section
     and the Section  of this  Agreement entitled  "Rights of  User by  the
     Lessee",  within a period of ten (10)  days after notice from the Port

                                        7


     Authority of such non-compliance,  the Port Authority may by  five (5)
     days' notice  terminate this Agreement  and the letting  hereunder and
     the same shall be and operate as a conditional limitation and have the
     same effect  as  if it  were  specifically included  as  a ground  for
     termination  under paragraph  (a)  of the  Section  of this  Agreement
     entitled "Termination".


     Section 8.     Maintenance and Repair

                    (a)  Except  to the  extent of such  items of  cleaning
     service as  may be supplied  by the  Port Authority as  stated in  the
     Section  of  this Agreement  entitled  "Services  and Utilities",  the
     Lessee shall  at all times  keep the premises  in a clean  and orderly
     condition and  appearance, together  with all fixtures,  equipment and
     personal  property  of  the Lessee  located  in  or  on the  premises,
     including without  limitation thereto the interior  surface of windows
     and both sides of all entrance doors.

                    (b)   The  Lessee  shall repair,  replace, rebuild  and
     paint  all  or any  part  of  the premises  which  may  be damaged  or
     destroyed  by the  acts  or  omissions  of the  Lessee's  contractors,
     customers, guests,  invitees or other  persons who are  doing business
     with the Lessee or who  are on or at  the premises or the World  Trade
     Center  with the  consent of  the Lessee  (such damage  or destruction
     occurring while such contractors, customers, guests, invitees or other
     persons are  at the premises or  the World Trade  Center in connection
     with business being transacted  with the Lessee or are at the premises
     or the  World Trade  Center with  the consent of  the Lessee)  and the
     Lessee shall repair, replace, rebuild and paint all or any part of the
     World Trade Center,  including the  premises which may  be damaged  or
     destroyed  by the  acts  or omissions  of  the Lessee,  its  officers,
     members, employees, agents and representatives.

                    (c)  The Lessee  shall take good care of  the premises,
     including  therein,  without  limitation  thereto,  walls, partitions,
     floors, ceilings,  doors  and  exteriors of  columns,  and  all  parts
     thereof,  and  all  equipment and  fixtures,  and  shall  do all  non-
     structural  preventive   maintenance  and  make  all   necessary  non-
     structural repairs, replacements, rebuilding and painting necessary to
     keep the premises in good condition befitting office  space in a first
     class  office building  and to  keep any  improvements, additions  and
     fixtures  made or  installed during  the term of  the letting  in good
     condition befitting office space in a first class office building.

                    (d)  In  the event the Lessee  fails to commence so  to
     make or do  any repair, replacements, rebuilding  or painting required
     by this Agreement within a  period of ten (10) days after  notice from
     the Port  Authority so  to  do, or  fails  diligently to  continue  to
     completion the repair, replacement,  rebuilding or painting of all  of
     the  premises required to be repaired, replaced, rebuilt or painted by
     the Lessee under the terms of this Agreement,  the Port Authority may,
     at its  option, and  in addition  to any other  remedies which  may be
     available to  it, repair, replace, rebuild or paint all or any part of
     the  premises  included in  the  said  notice,  the  Port  Authority's
     reasonable cost  thereof to  be paid  by the Lessee  on demand.   This
     option or  the exercise thereof shall not be deemed to create or imply
     any obligation or duty to the Lessee or others.

                                        8


                    (e)   The Port Authority agrees that during the term of
     the letting hereunder it  will maintain and operate those  portions of
     the Facility affecting the premises and those portions of the Facility
     utilized  by the Lessee  for access to  the premises and  will provide
     services  to the premises and will maintain the systems providing such
     services to the premises  all substantially in the  manner and at  the
     level existing  on the  date of  this Agreement.   The  Port Authority
     further agrees to maintain the  public areas in the building of  which
     the  premises are  a part,  to clean  the exterior  of windows  in the
     premises and to make  structural repairs to the exterior  walls, floor
     slab and structural building supporting members in the premises to the
     extent necessary to keep  the premises in a reasonably  good condition
     for the operations of  the Lessee under this Agreement,  provided that
     nothing herein shall relieve  the Lessee from the requirements  of the
     Section of this Agreement entitled "Governmental Requirements".

     Section 9.     Casualty

                    (a)   In  the event  that, as  a result  of a  casualty
     insurable  under the New York  standard form of  fire insurance policy
     and  extended coverage endorsement, the premises or areas at the World
     Trade Center other  than the  premises are damaged  (such areas  other
     than the premises as may be damaged hereinafter in this Section called
     the  "damaged areas") without the  fault of the  Lessee, its officers,
     members, employees,  customers, guests, invitees or  other persons who
     are doing business with the Lessee or who are on the premises with the
     Lessee's consent, so as  to render the premises untenantable  in whole
     or part, then 

                         (1)    if  the   Port  Authority  finds  that  the
               necessary repairs or rebuilding  can be completed within two
               hundred  seventy  (270) days  after  the  occurrence of  the
               damage, the Port Authority shall  repair or rebuild with due
               diligence,  and the  rental  hereunder shall  be abated,  as
               hereinafter  provided  in  the  Section  of  this  Agreement
               entitled "Abatement of Rental", only for the period from the
               occurrence  of the damage to the earlier of (i) fifteen (15)
               days from the notification of  the completion of the repairs
               or  rebuilding   or  (ii)   the  commencement   of  business
               operations  by  the  Lessee  in  the  damaged  areas  of the
               premises; or

                         (2)  if the Port Authority finds that such repairs
               or rebuilding cannot be completed within two hundred seventy
               (270) days after the occurrence of the damage, then the Port
               Authority  shall  have  options:  (i) to  proceed  with  due
               diligence to  repair or to  rebuild the premises  or damaged
               areas as necessary in which event the rental hereunder shall
               be  abated  as provided  in  the Section  of  this Agreement
               entitled "Abatement  of Rental" only for the period from the
               occurrence  of the damage to the earlier of (x) fifteen (15)
               days from notification of  the completion of the  repairs or
               rebuilding or (y) the commencement of business operations by
               the  Lessee in the damaged areas of the premises; or (ii) to
               terminate the letting as to the entire premises.

                    (b)  In the event of damage to the  premises or damaged
     areas under  circumstances described in paragraph (a)  of this Section

                                        9


     9, the Port Authority within thirty  (30) days after the occurrence of
     the damage will furnish to the Lessee in writing a good faith estimate
     of the time required to complete the repairs or  rebuilding, such good
     faith estimate to be arrived at by the Port Authority after consulting
     with its  Chief Engineer.  In  the event the  Port Authority estimates
     that  the repairs or rebuilding cannot be completed within two hundred
     seventy  (270) days  after the  occurrence of  the damage,  then, upon
     written notice to the Port Authority within twenty (20) days following
     its  receipt of the Port  Authority's estimate, the  Lessee shall have
     the right  to terminate the  letting as to  the entire premises  under
     this Agreement, provided  that prior to or  contemporaneously with the
     exercise of such  right to  terminate this Agreement  and the  letting
     hereunder,  a responsible officer of  the Lessee shall  certify to the
     Port  Authority that on an economic and operational basis the premises
     cannot be used by the Lessee for the operations described in Section 3
     of this Agreement prior  to the substantial completion of  the repairs
     or rebuilding  and provided  further that  the Lessee  is not under  a
     notice of  termination from the Port  Authority either on the  date of
     the giving of  its notice to  the Port Authority  or on the  effective
     date thereof.  Termination  pursuant to this paragraph (b)  shall have
     the same force and effect as if the termination date were the original
     expiration date provided in this Agreement.

                    (c)  If damage  to the premises or  damaged areas under
     circumstances described in  paragraph (a) of  Section 9 occurs  during
     the period which constitutes the last two (2) years of the term of the
     letting,  the provisions of this Section 9 shall be applicable, except
     that  for  the purpose  of applying  such  provisions the  two hundred
     seventy (270) day periods referred to  in paragraphs (a) and (b) above
     of this Section 9 shall  in each instance be deemed changed  to ninety
     (90) days.

                    (d)  The  parties do hereby stipulate  that neither the
     provisions of Section 227 of the Real Property Law of the State of New
     York nor those  of any other similar statute shall  extend or apply to
     this Agreement.

                    (e)  The Lessee shall give the Port Authority immediate
     notice in  case of any fire,  accident or casualty in  the premises or
     elsewhere in the World Trade Center if the occurrence elsewhere in the
     World Trade Center is known to and involves  the Lessee, its officers,
     members,  employees, agents, representatives, contractors, or is known
     to any  of them  and involves  customers,  guests or  invitees of  the
     Lessee.

                    (f)  In the event  of a partial or total destruction of
     the  premises, the Lessee shall as  soon as practicable remove any and
     all of  its property and all  debris from the premises  or the portion
     thereof destroyed and if the  Lessee does not promptly so  remove, the
     Port  Authority may discard the same after  giving the Lessee five (5)
     days' prior  notice of such or  may remove the Lessee's  property to a
     public warehouse for deposit or retain the same  in its own possession
     and at  its discretion may sell  the same at either  public auction or
     private  sale, the  proceeds of  which shall be  applied first  to the
     expenses of removal, storage and sale, second to any sums  owed by the
     Lessee to the Port Authority, with any balance remaining to be paid to
     the Lessee; if  the expenses of such  removal, storage and sale  shall
     exceed  the proceeds of sale, the Lessee  shall pay such excess to the

                                       10


     Port  Authority  upon  demand.     Notwithstanding  anything  in  this
     Agreement to the contrary,  the Lessee's restoration obligations under
     this  Agreement  which  would   otherwise  apply  upon  expiration  or
     termination of this Agreement shall not be applicable upon termination
     of  this Agreement  pursuant  to  this Section  9  to the  portion  or
     portions of the premises damaged  under the circumstances described in
     paragraph (a)  above except  to the  extent that  the Lessee  shall be
     required to remove all of its trade fixtures,  equipment and any other
     personalty from such damaged portion or portions of the premises.

                    (g)  The provisions of paragraph  (a) of this Section 9
     shall also  be applicable to  damage to  the premises and  the damaged
     areas  caused by  the  fault of  the  Lessee, its  officers,  members,
     employees, customers, guests, invitees and other persons who are doing
     business with the Lessee, or who are on the premises with the Lessee's
     consent, but notwithstanding such  application or any action  taken by
     the Port Authority  or the  Lessee pursuant to  paragraph (a) of  this
     Section 9,  including without limitation, termination  of the letting,
     the Lessee's obligation to  repair and rebuild under paragraph  (b) of
     Section 8 shall continue in full force and effect except to the extent
     released pursuant to the  provisions of the Section of  this Agreement
     entitled "Liability  Insurance".   In  connection with  damage to  the
     premises or the damaged areas which is due to the fault of the Lessee,
     its officers,  employees, customers,  invitees or other  persons doing
     business  with the  Lessee,  the Lessee  shall not  be entitled  to an
     abatement  of rentals  unless and  only  to the  extent that  the Port
     Authority actually receives proceeds of rental insurance in connection
     with  such damage, it being  understood that the  Port Authority shall
     not be obligated to maintain or procure such insurance.

     Section 10.    Indemnity

                    (a)    The Lessee shall indemnify and hold harmless the
     Port Authority, its Commissioners, officers, agents and employees from
     (and shall reimburse the Port Authority for the Port Authority's costs
     or expenses including reasonable  legal expenses and the costs  to the
     Port Authority of  its in-house legal  counsel incurred in  connection
     with the defense of) all claims and demands of third persons including
     but not  limited to  those for  death, for  personal injuries, or  for
     property  damages, arising  out  of  any  default  of  the  Lessee  in
     performing  or observing any term  or provision of  this Agreement, or
     out of the use or occupancy of the premises by the Lessee or by others
     with its  consent, or  out of  any of  the acts  or  omissions of  the
     Lessee,  its officers,  members,  employees, agents,  representatives,
     contractors,  customers, guests,  invitees and  other persons  who are
     doing business with  the Lessee or  who are at  the premises with  the
     Lessee's consent where such acts or omissions are on  the premises, or
     arising out  of any  acts or omissions  of the  Lessee, its  officers,
     members,  employees, agents  and  representatives where  such acts  or
     omissions are elsewhere at the World Trade Center.

                    (b)     If so  directed, the  Lessee shall  at its  own
     expense defend any  suit based upon any such claim  or demand (even if
     such suit, claim or demand is groundless, false or fraudulent), and in
     handling  such  it  shall   not,  without  obtaining  express  advance
     permission from the General  Counsel of the Port Authority,  raise any
     defense involving in any way the jurisdiction of the tribunal over the
     person of the Port Authority, the immunity of the  Port Authority, its

                                       11


     Commissioners, officers, agents or employees,  the governmental nature
     of  the Port  Authority or  the provision  of any  statutes respecting
     suits against the Port Authority.

     Section 11.    Ingress and Egress

                    The Lessee solely  for itself, its  officers, employees
     and such business invitees as  are at the premises in connection  with
     the transaction of the regular business of the Lessee, shall  have the
     right  of ingress and egress between the premises and the City streets
     outside  the World  Trade Center.   Such  right shall be  exercised by
     means of  such  corridors, lobbies,  public  areas and  pedestrian  or
     vehicular  ways, and by means  of such elevators,  escalators or other
     facilities for movement of persons or property, to be  used subject to
     all the provisions of this Agreement and in common with others  having
     rights of passage and movement  within the World Trade Center,  as may
     from  time to time be designated by  the Port Authority for the use of
     the public.  The use of any such facility, way or other area  shall be
     subject to the rules and  regulations of the Port Authority which  are
     now in effect  or which may hereafter be promulgated  for the safe and
     efficient operation of  the World  Trade Center.   The Port  Authority
     may,  at any time, temporarily  or permanently close,  move, change or
     limit  the use  of,  or consent  to or  request  the closing,  moving,
     changing or  limitation of the use  of, any such facility,  way or any
     other area  at or near  the World Trade Center  presently or hereafter
     used as such, so long as  a reasonably comparable means of ingress and
     egress as  provided above remains available to the Lessee.  The Lessee
     shall  not do or permit anything to  be done which will interfere with
     the  free access  and  passage  of others  to  space  adjacent to  the
     premises or in any areas, streets, ways, facilities and walks near the
     premises.

     Section 12.    Construction by the Lessee

                    (a)  Except as expressly  provided in this  Section 12,
     the Lessee  shall not  erect any structures,  make any  modifications,
     alterations, additions,  improvements, repairs  or replacements or  do
     any construction work on or  to the premises, or install  any fixtures
     in  or on the premises  (other than trade  fixtures, removable without
     injury to the premises  and other than purely decorative  changes such
     as  painting, the Lessee  to notify the  Port Authority  not less than
     five (5) business days prior to making any decorative changes  and the
     Lessee  shall  not  commence or  continue  such  changes  if the  Port
     Authority  advises the Lessee that such changes are not decorative and
     require  the prior approval of  the Port Authority)  without the prior
     consent  of the  Port Authority,  and in  the event  any construction,
     improvement, alteration, modification, addition, repair or replacement
     is made or done with or without such consent and unless the consent of
     the Port  Authority shall expressly provide otherwise,  the same shall
     immediately become the property  of the Port Authority and  any change
     or removal of same by the  Lessee, except for trade fixtures removable
     without injury  to  the premises,  either during  the term  or at  the
     expiration thereof shall  be in  accordance with and  pursuant to  the
     terms  of this  Section.   Notwithstanding the  foregoing, immediately
     upon notice  from the  Port Authority  given at  any  time during  the
     letting, the  Lessee shall remove  or change any  of the same  made or
     done by  it without the Port  Authority's consent, and in  the case of
     any of  the same made or  done with the Port  Authority's consent, the

                                       12


     Lessee if so required by notice  from the Port Authority, shall remove
     and  restore  the following  improvements  and  installations made  or
     installed  by  the  Lessee  in  the  premises   immediately  upon  the
     expiration or termination of the letting, or immediately upon  receipt
     of such  notice as  may be  given within thirty  (30) days  after such
     expiration   or  termination:     modular   furniture,  computer   and
     telecommunications   equipment   and  wiring,   all   standard  office
     equipment, inventories, removable fixtures and other personal property
     of the Lessee or for  which the Lessee is responsible, and  the Lessee
     shall repair  any damage  caused  by any  of such  removal  work.   In
     addition, immediately upon expiration or termination of the letting or
     immediately upon receipt  of notice from the Port Authority  as may be
     given within thirty  (30) days after  such expiration or  termination,
     the  Lessee shall  be  required to  restore all  floor slabs  or other
     vertical  penetrations  and  to  restore  all  other  structural  work
     performed by  the Lessee  to the  condition existing at  the time  the
     premises were made available  to the Lessee, including the  removal of
     all stairwells  installed in the premises by the Lessee.  In the event
     the  Lessee removes electrical or  plumbing fixtures, the Lessee shall
     be required to  cap all  altered electrical and  plumbing lines  flush
     with  walls, floors and ceilings but nothing in this sentence shall be
     construed  as  an obligation  of the  Lessee  to remove  electrical or
     plumbing fixtures  unless such obligation is imposed elsewhere in this
     Section.    Nothing herein  shall be  deemed to  affect or  impair the
     Lessee's  maintenance and  repair obligations  set forth  elsewhere in
     this  Agreement.    With  respect  to  any  modifications,  additions,
     alterations, improvements, installations or  construction made or done
     by the Port Authority at the request  of the Lessee either prior to or
     during  the term  of  the  letting, the  Lessee  shall  have the  same
     obligations as provided above with respect to that made or done by the
     Lessee with the Port Authority's consent.

                    (b)  The  Lessee has thoroughly  examined and inspected
     the premises and agrees, except for  the work described in the Section
     of this Agreement entitled "Port Authority Work", to take the premises
     in its  "as is" condition  on the  date of  this Agreement,  provided,
     however that if  there is a latent condition  existing in the premises
     on the Prior Entry Date requiring structural work, which condition was
     not  known  by  the  Lessee  at the  time  of  its  execution  of this
     Agreement,   then  the   Lessee  shall   notify  the   Port  Authority
     expeditiously  upon  its  discovery of  such  condition  and  the Port
     Authority, at its  cost and expense,  will correct same.   The  Lessee
     acknowledges  that  it  has  not  relied upon  any  representation  or
     statement of  the Port Authority  or of  its Commissioners,  officers,
     agents or  employees as  to the  suitability of  the premises  for the
     operations  permitted thereon by this  Agreement.  The Port Authority,
     except  for  the  work described  in  the  Section  of this  Agreement
     entitled "Port Authority Work", shall have no obligation hereunder for
     finishing  work or preparation of  the premises for  the Lessee's use.
     The Lessee, subject to the provisions of paragraph (g) of this Section
     12, agrees  to perform at its  sole cost and expense  all construction
     and installation work that it  may require to finish off and  decorate
     the premises.  Without  limiting the generality of the  foregoing, the
     Lessee  acknowledges that  facilities  for heat,  ventilation and  air
     cooling have heretofore been  installed in the premises pursuant  to a
     certain  design   configuration  and  the  Port   Authority  makes  no
     representations that  such heat, ventilation and  air-cooling shall be
     adequate for  the Lessee's needs  and in the  event any  alteration to

                                       13


     such facilities shall be required the cost of the same  shall be borne
     by the Lessee.   Nothing in the preceding sentence shall  be construed
     to relieve the Port Authority from providing heat, ventilation and air
     cooling  in accordance with the specifications set forth in Schedule D
     attached hereto.

                    (c)  With  respect  to all  modifications, alterations,
     additions, improvements,  repairs, replacements or  other construction
     or installation work  proposed to be  performed in or on  the premises
     (hereinafter referred to as  the "construction and installation work")
     the Lessee  shall submit  to the  Port Authority  for  its approval  a
     construction application for the premises in the  form attached hereto
     as Exhibit TAA  setting forth in detail  and by appropriate plans  and
     specifications the construction and  installation work proposed by the
     Lessee to finish off and  decorate the premises and the manner  of and
     time  periods  for   performing  the  same.     No  construction   and
     installation work shall  be commenced  by the Lessee  in the  premises
     until the  construction application and plans  and specifications have
     been  approved by  the Port  Authority.   In the  event of  any incon-
     sistency between the provisions of this Agreement and the construction
     application, the provisions of this Agreement shall control.  The data
     to be supplied  by the Lessee shall  describe in detail  the fixtures,
     equipment and  systems, if any, to  be installed by the  Lessee or, if
     already  installed, to be modified  by the Lessee  including those for
     the  emission, handling  and distribution  of heat,  air conditioning,
     domestic hot and cold water and electrical and other systems and shall
     show the  proposed method of tying in the same to the utility lines or
     connections  provided by  the  Port Authority  either  on or  off  the
     premises.  The Lessee shall install all electrical distribution equip-
     ment  required,  including  but  not  limited  to,  service  switches,
     excluding  the disconnect switches,  current transformer cabinets and,
     if the consumption  and demand for electricity by the  Lessee is to be
     metered,  meter  pans  suitable  for  the  installation  by  the  Port
     Authority  of an  electric  meter or  meters,  the Port  Authority  to
     provide and install such meter or meters at its sole cost and expense.
     The Lessee shall be responsible at its sole expense  for retaining all
     architectural,  engineering  and   other  technical  consultants   and
     services as may be reasonably  required by the Port Authority  and for
     developing,  completing and  submitting  detailed  plans and  specifi-
     cations for the work.  The plans and specifications to be submitted by
     the Lessee  to the Port Authority  shall bear the seal  of a qualified
     architect or professional  engineer and shall be  in sufficient detail
     for  a contractor  to perform  the work.   If  the Lessee's  plans and
     specifications shall satisfy and be in conformance with the applicable
     requirements of the Port Authority's Tenant Construction Review Manual
     issued by the Port Authority Engineering Department dated March, 1984,
     revised  March, 1990,  together with  Amendment No.  1 dated  October,
     1990, (and as  the same may be  further amended prior to the  date the
     Lessee submits  its plans and specifications) the  Port Authority will
     approve  same.  In the event the  Lessee disputes an interpretation or
     application by  the Port  Authority of  any of  the provisions  of the
     Construction  Manual with respect  to any work to  be performed by the
     Lessee  pursuant  to this  Section  12, then  and  in such  event such
     dispute shall  be diligently  resolved by the  Port Authority's  Chief
     Engineer.    In the  event  that  the Lessee  in  connection with  the
     performance  of the  initial construction  and finishing  work in  the
     premises shall give  to the Port Authority  not less than twenty  (20)
     business  days' notice of the date  that the Lessee intends to deliver

                                       14


     its construction application  and plans and specifications to the Port
     Authority  and the  Lessee  shall actually  deliver such  construction
     application and plans and specifications to the Port Authority on such
     date and  such construction  application and plans  and specifications
     shall cover  all of  the initial  construction  and installation  work
     necessary to finish off and  decorate the premises (hereinafter called
     the "Pre-Appointment  Process"), then  the Port Authority  will review
     the same and forward its  comments thereon to the Lessee within  seven
     (7)   business  days  after  the  Port  Authority's  receipt  of  such
     construction  application and  plans and  specifications and  the Port
     Authority will  review and comment  on any resubmission  of corrected,
     modified or amended plans and specifications within seven (7) business
     days after the Port Authority's receipt thereof.  All comments made by
     the Port  Authority to the  Lessee pursuant to  this Section  shall be
     made in writing and all comments by the Port Authority with respect to
     the Lessee's plans and specifications shall  be made with specificity.
     If the total  of the number of business days  actually required by the
     Port  Authority for review of all submissions and resubmissions of the
     Lessee's construction application and plans and specifications for the
     initial  construction and  finishing work  during the  Pre-Appointment
     Process  should be in  excess of the  total of the  number of business
     days  allocated for the Pre-Appointment Process to all such reviews of
     the  Lessee's   submissions  and   resubmissions  of  its   plans  and
     specifications  as provided  above, then  the two  hundred seventy-one
     (271) day period from the commencement date of the term of the letting
     used to determine the Rent Commencement Date shall be increased by one
     (1) day  for each of  such excess  business days.   The Lessee  hereby
     agrees that such increase  in the number of days from the commencement
     date of  the letting to the  Rent Commencement Date shall  be the sole
     remedy available to the Lessee in the event  the Port Authority fails,
     within the  time provided herein for the  Port Authority to respond to
     the   Lessee's  submission   or  resubmission   of  its   construction
     application and  plans and specifications  during the  Pre-Appointment
     Process.   In  the event the  Lessee does  not elect to  use the "Pre-
     Appointment  Process",  then  the  Port  Authority  shall  review  the
     construction application and all plans and specifications submitted by
     the Lessee for the initial work and will forward its  comments on same
     within fifteen (15) business  days after its receipt of  the aforesaid
     submission,  provided  such  construction application  and  plans  and
     specifications cover all of  the initial construction and installation
     work necessary to  finish off  and decorate the  premises (unless  the
     estimated amount of the work to be performed by the Lessee as shown on
     the construction application is  in excess of $3,000,000.00,  in which
     case  the Port Authority will  so respond within  twenty (20) business
     days after such submission by the  Lessee) and will review and comment
     on  any resubmissions  within twelve  (12) business  days  (unless the
     estimated amount of the work to be performed by the Lessee as shown on
     the construction  application is greater than  $3,000,000.00, in which
     case the Port Authority will so respond in  14 business days).  If the
     total of the  number of  business days actually  required by the  Port
     Authority for the review  of all submissions and resubmissions  of the
     Lessee's plans and  specifications for  the initial work  shall be  in
     excess of  the total of the  number of business days  allocated to all
     reviews of the  Lessee's submissions and resubmissions as  provided in
     the preceding  sentence, then  the two  hundred seventy-one (271)  day
     period from the  commencement date of the term of  the letting used to
     determine the Rent Commencement Date shall be increased by one (1) day
     for each of such excess business days.  The Lessee  hereby agrees that

                                       15


     such increase in the number of days from the commencement  date of the
     letting  to  the  Rent Commencement  Date  shall  be  the sole  remedy
     available  to the Lessee in the  event the Port Authority fails within
     the time  provided  for above  in  this paragraph  to  respond to  the
     Lessee's  submission or resubmission.  The Lessee shall not engage any
     contractor or permit  the use  of any subcontractor  unless and  until
     each  such contractor or subcontractor shall have been approved by the
     Port Authority.  The Port Authority hereby approves the AJ Contracting
     Company,  Inc. as the Lessee's general contractor.  The Port Authority
     further agrees that within  five (5) business days after  a request is
     made  by the  Lessee,  it will  notify  the Lessee  as  to whether  it
     approves  or disapproves any  contractor or subcontractor  as to which
     the Lessee seeks Port Authority approval.  If the Port Authority shall
     fail to notify the Lessee in writing within such five (5) business day
     period  that   such  contractor   or  subcontractor  is   approved  or
     disapproved, such contractor or subcontractor shall  be deemed to have
     been approved by the  Port Authority for performance  of the work  for
     which  such contractor  or subcontractor  was  submitted.   The Lessee
     shall  include in each such contract or subcontract such provisions as
     the  Port  Authority  may  reasonably approve  or  reasonably  require
     including,  without  limitation  thereto,  provisions  regarding labor
     harmony.  The  Lessee hereby assumes the risk of loss or damage to all
     of the  construction and  installation work  prior  to the  completion
     thereof.  If such loss or damage shall occur prior to the delivery  by
     the  Port Authority's  Assistant Director  Physical Facilities,  World
     Trade Department, of the certificate of substantial completion  to the
     Lessee  and  the  Port  Authority  as  hereinafter  provided  in  this
     paragraph  (c), the Lessee, subject to the provisions of paragraph (f)
     of the Section of this Agreement entitled "Liability Insurance", shall
     forthwith  repair,   replace  and  make  good   the  construction  and
     installation  work and the property of the Port Authority without cost
     or  expense to the Port Authority.  If such loss or damage shall occur
     subsequent  to delivery  of such  certificate, the  provisions of  the
     Section  of this  Agreement entitled  "Casualty" shall  be applicable.
     The  Lessee shall  itself and  shall also  require its  contractors to
     indemnify  and hold  harmless the  Port Authority,  its Commissioners,
     officers,  agents  and employees  from  and  against  all  claims  and
     demands, just or unjust, of  third persons (including employees, offi-
     cers, and agents of  the Port Authority) arising  or alleged to  arise
     out of the performance  of the construction and installation  work and
     for all expenses, including  without limitation thereto legal expenses
     (including  the  costs to  the Port  Authority  of its  in-house legal
     counsel), incurred  by it and  by them in  the defense, settlement  or
     satisfaction thereof, including without limitation thereto, claims and
     demands  for death, for personal injury or for property damage, direct
     or consequential, whether they arise from the acts or omissions of the
     Lessee, of any contractors of the Lessee, of the Port Authority, or of
     third  persons,  or from  acts  of  God or  of  the  public enemy,  or
     otherwise,  excepting  only  claims  and  demands  which  result  from
     affirmative   willful   acts  done   by   the   Port  Authority,   its
     Commissioners,  officers, agents  and  employees with  respect to  the
     construction and installation work, provided, however, that the Lessee
     shall  not  be required  to indemnify  the  Port Authority  where such
     indemnity  would be precluded pursuant to the provisions of Section 5-
     322.1  of  the General  Obligations  Law  of the  State  of New  York.
     Notwithstanding the provisions of the foregoing sentence, with respect
     to the  Additional Lessee Work, as such term is defined in the Section
     of  this Agreement  entitled "Port  Authority Work;  Additional Lessee

                                       16


     Work",  the  Lessee's  indemnification  obligations therein  shall  be
     limited to claims  and demands arising or alleged to  arise out of the
     negligent  acts of the Lessee, its officers and employees, but nothing
     herein  shall limit  the indemnification  obligations of  the Lessee's
     contractor as stated  aforesaid.   The Lessee shall,  and shall  cause
     each  of its contractors and subcontractors to, obtain and maintain in
     force  such  insurance   coverage,  including  without   limitation  a
     contractual liability endorsement covering the  obligations assumed by
     the Lessee in the three preceding sentences.  All work to be performed
     by  the  Lessee  hereunder  shall  be  in  accordance  with  the  said
     construction application  and final plans and  specifications approved
     by the Port Authority, except that all aspects of the construction and
     installation work which affect life safety shall be performed strictly
     in accordance  with the construction  application and final  plans and
     specifications approved  by the  Port Authority,  shall be  subject to
     inspection by the Port Authority  during the progress of the  work and
     after  the completion thereof and the Lessee  shall redo or replace at
     its  own expense  any  work  not done  in  accordance  therewith.   In
     connection therewith the Lessee agrees not to install ceiling tiles in
     the  premises or  otherwise  cover  up  the  ceiling  until  the  Port
     Authority  has inspected any ceiling  work performed by  the Lessee in
     the premises and the Port Authority agrees to inspect any ceiling work
     performed  by  the Lessee  within five  (5)  business days  after such
     request is made  by the Lessee.   Upon  substantial completion of  the
     initial  construction  and installation  work to  be performed  by the
     Lessee  pursuant  to the  construction  application  the Lessee  shall
     deliver to the Port  Authority a certificate by an  authorized officer
     of  the Lessee and a  certificate by the  Lessee's qualified architect
     and/or professional  engineer, each  certifying that the  initial con-
     struction and installation work has been performed  in accordance with
     the construction  application and  the final plans  and specifications
     approved by the  Port Authority  (or strictly in  accordance with  the
     plans and specifications approved by the Port Authority in the case of
     life-safety  matters)  and the  provisions  of this  Agreement  and in
     compliance with the Port Authority's Tenant Construction Review Manual
     and   all  applicable   governmental  laws,   ordinances,  enactments,
     resolutions,  rules, regulations  and  orders.    Notwithstanding  the
     foregoing,  with  respect  to  the  certification  set  forth  in  the
     preceding  sentence,  the  Lessee  may notify  the  Port  Authority in
     writing  that   the  certification   of  the  Lessee's   architect  or
     professional  engineer shall also be deemed to be the certification of
     the Lessee with the same force and effect as if given directly  by the
     Lessee.  The Port Authority shall inspect the initial construction and
     installation work and within fifteen (15) business days  after receipt
     of  such certification (or within ten (10) business days after receipt
     of  a  resubmission  of  such  certification),  the  Port  Authority's
     Assistant Director, Physical Facilities, World Trade Department, shall
     do  either  of  the following  (i)  if  the  initial construction  and
     installation work has been substantially completed as certified by the
     Lessee  and such  architect  and/or engineer,  the Assistant  Director
     shall so certify to the  Port Authority and to the Lessee,  subject to
     the  condition  that  all   risks  thereafter  with  respect   to  the
     construction  and  installation  work  covered  by  such  construction
     application  and any liability therefor for negligence or other reason
     shall be  borne by the Lessee, or (ii) notify  the Lessee and the Port
     Authority that the  work has  not been substantially  completed as  so
     certified  by the Lessee  and its architect  or professional engineer,
     such notification to specifically state the objections with respect to

                                       17


     such  certification.    For  purposes  of  this  Section  "substantial
     completion" shall  mean completion of  all non life-safety  working in
     accordance  with  the approved  plans  and  specifications except  for
     minor,  insubstantial "punch  list" items and  completion of  all work
     relating to life-safety strictly in accordance with the approved plans
     and  specifications.   If the  total of  the number  of  business days
     actually required by the Port Authority's Assistant Director, Physical
     Facilities, World  Trade Department, to respond  to all certifications
     and recertifications of  the Lessee and its architect  or professional
     engineer  with respect to the initial work  should be in excess of the
     total of the number of business  days allocated, then the two  hundred
     seventy-one (271) day period from the commencement date of the letting
     used to determine the Rent Commencement Date shall be increased by the
     number of  such excess  business days.   The Lessee  shall not  use or
     permit  the  use  of  any  portion  of  the  premises  in  which   the
     construction and  installation work is being  performed for conducting
     its business operations until such certification is received from said
     Assistant  Director, Physical Facilities, and the Lessee shall not use
     or  permit  the use  of  such portion  of  the premises  even  if such
     certification  is   received  with  respect   to  a  portion   of  the
     construction   and  installation  work  if  said  Assistant  Director,
     Physical  Facilities,  states  in  any such  certification  that  such
     portion  of the premises cannot be used until other specified portions
     of  the  construction  and  installation work  are  completed.    Upon
     completion  of the  initial  work the  Lessee  shall supply  the  Port
     Authority with "as built" drawings in form and number requested by the
     Port Authority.

                    (d)  The  Lessee  shall be  solely responsible  for the
     plans  and specifications  used  by  it,  except  for  the  plans  and
     specifications  prepared by  the Port Authority  and furnished  to the
     Lessee  for the performance of  the Lessee's Additional  Work, and for
     the  adequacy and sufficiency of such plans and specifications and all
     the improvements  depicted thereon  or covered thereby,  regardless of
     the consent thereto or  approval thereof by the Port Authority  or the
     incorporation   therein   of  any   Port  Authority   requirements  or
     recommendations.   The  Port Authority  shall have  no  obligations or
     liabilities in connection  with the performance of  the work performed
     by the  Lessee or on its  behalf or the contracts  for the performance
     thereof  entered into  by  the Lessee.    Any warranties  extended  or
     available to the Lessee in connection with the aforesaid work shall be
     for the benefit of the Port Authority as well as the Lessee.

                    (e)  Title  to  and  property in  the  construction and
     installation work and to all fixtures, equipment and systems installed
     pursuant  to this Section and  any replacements thereof  shall vest in
     the Port Authority upon  the construction, installation or replacement
     thereof  and  the  Lessee   shall  execute  such  necessary  documents
     confirming the same as the Port Authority may require.

                    (f)  Without limiting  or affecting  any other term  or
     provision of this  Agreement, the Lessee  shall be solely  responsible
     for the  design, adequacy and  operation of  all utility,  mechanical,
     electrical,  communications and other systems made or installed by the
     Lessee in the  premises and  shall do all  preventive maintenance  and
     make all repairs,  replacements and rebuilding necessary  to keep such
     systems and  all other improvements, additions  and fixtures, finishes
     and  decorations made  or installed  by the  Lessee (whether  the same

                                       18


     involves  structural  or   non-structural  work)  in  good   condition
     befitting a tenancy in a first  class office building.  The Lessee has
     advised  the  Port  Authority  that  it  may  elect  as  part  of  its
     construction  and finishing work to reinforce the floor located in the
     portion of  the premises shown on Exhibit A attached to this Agreement
     and to perform  poke throughs  and install drains  therein.  The  Port
     Authority  will  cooperate with  the Lessee  to  gain access  to space
     located on the 22nd floor of  the South Tower Building for the purpose
     of enabling the  Lessee to  perform such reinforcement  work, but  the
     Lessee  understands that the Port  Authority is offering no assurances
     that such tenant  currently in occupancy on said 22nd floor will grant
     access to  the Lessee or on what terms and conditions such access will
     be  granted and the Lessee  further understands and  agrees that there
     will be no  liability to the Port Authority if  such tenant refuses to
     grant access.  If such  access is so granted the Lessee  hereby agrees
     to  indemnify  the Port  Authority from  and  against all  claims made
     against the  Port Authority arising  or resulting from  performance of
     such  reinforcement work  by the  Lessee.   In the  event that  during
     performance of such work the Lessee discovers the presence of asbestos
     or asbestos-containing materials in the ceiling of the said 22nd floor
     space, then the Lessee shall immediately notify the Port Authority who
     will  diligently  remove  same  at  its  cost  and  expense  and  will
     refireproof,  if necessary,  the ceiling  area containing  asbestos or
     asbestos-containing   materials,  provided   that  such   asbestos  or
     asbestos-containing materials were not placed therein by the Lessee or
     its  contractor.   The Lessee  shall not  commence performance  of any
     reinforcement  work unless and  until the Port  Authority has approved
     the Lessee's construction application and plans and specification with
     respect to same.

                    (g)  The Port Authority in connection with the Lessee's
     initial construction  and installation work performed  in the premises
     will pay to the Lessee an amount  equal to the lesser of (1) the  cost
     of such initial  construction and installation  work performed in  the
     premises  or (2)  the  sum of  Three  Million Six  Hundred  Forty-four
     Thousand Five Hundred Forty-six  Dollars and No Cents ($3,644,546.00),
     such  lesser amount  being hereinafter  referred to  as  the "Lessee's
     Finishing Allowance."  "Cost" as used herein shall mean the sum of (i)
     direct  labor and material costs  and contract costs  for the purchase
     and installation of fixtures, equipment, mill work and other finishing
     and decorating work, including  the cost of purchase and  installation
     of  modular  partition  systems  and  other  employee  work  stations,
     telecommunications equipment and wiring, to the extent all of same are
     actually installed  in,  affixed  or  annexed to  the  premises,  (ii)
     construction    management,   engineering,    architectural,   project
     consulting,  planning and  design  and similar  professional fees  and
     expenses  which, taken together, do not exceed thirty percent (30%) of
     the total  of the aforesaid costs set forth in clause (i) above, (iii)
     moving and relocation  expenses incurred by  the Lessee in  connection
     with the relocation to the premises of its property and equipment from
     its current space at 110  William Street, New York, New York  and from
     the space currently leased by Unity Fire and General Insurance Company
     (a wholly  owned subsidiary of the Lessee)  from the Port Authority on
     the 29th floor of the  South Tower Building at the World  Trade Center
     and (iv) utility,  freight elevator and standby labor charges incurred
     during  construction,  inspection,  filing,  sign off  and  all  other
     charges and fees imposed by the Port Authority in connection with such
     work.  In no event whatsoever shall "cost", as defined and computed in

                                       19


     this paragraph, include any expenses, outlays or charges whatsoever by
     or for the  account of the Lessee  for or in connection  with any work
     performed by the Lessee pursuant to paragraphs (c), (d) and (e) of the
     Section  of the  Agreement entitled  "Port Authority  Work; Additional
     Lessee  Work",  or in  connection with  equipment  or fixtures  or the
     making  of any finishing or  decorating work unless  such are actually
     and completely  installed in and  or made  to the premises,  nor shall
     "cost"  include the  cost  of any  equipment, fixtures  or improvement
     which  is   secured  by   liens,  mortgages,  other   encumbrances  or
     conditional bills of sale,  nor shall "cost" include any  payment made
     to organizations which  are owned by or  in common ownership  with the
     Lessee.  The  Lessee's Finishing Allowance will be paid  to the Lessee
     as follows:   not more  than once  each calendar  month following  the
     calendar month  in which  the Lessee  commences  the construction  and
     installation work in the  premises pursuant to the provisions  of this
     Section  12,  the  Lessee shall  deliver  a  certificate  to the  Port
     Authority signed  by a designated  representative of the  Lessee which
     shall certify  the amount of the payments made by the Lessee which are
     properly   includible  in   the  Lessee's   cost  of   performing  the
     construction  and  installation  work during  the  preceding  calendar
     month,  each  such  certificate  to  set  forth the  total  cumulative
     payments  constituting the Lessee's cost  made by the  Lessee from the
     commencement  of the construction and installation work to the date of
     the  certificate  and   each  such  certificate  also   to  contain  a
     certification  by the Lessee or  at the Lessee's  option, the Lessee's
     architect   or   professional   engineer   (provided   that   if  such
     certification is  made by such architect or engineer, then it shall be
     with the same force and effect as if such certification  had been made
     directly  by the  Lessee  itself) that  the  portion of  the  Lessee's
     construction and installation work performed  by the Lessee since  the
     last  such  certificate  and  covered  by  such  certificate  has been
     performed  in  accordance with  the terms  of  this Agreement  and the
     Construction Application.  Within  30 days after the delivery  of each
     such certificate  by the Lessee, the  Port Authority shall pay  to the
     Lessee the  amount constituting the  Lessee's cost  of performing  the
     construction and installation work  and paid by the Lessee  during the
     preceding calendar month,  less ten  percent (10%) of  the portion  of
     such cost attributable to clause (i) above (but only less five percent
     (5%) thereof subsequent  to the  date that the  Lessee's architect  or
     engineer certifies to the  Port Authority that at least  fifty percent
     (50%) of the  entire finishing  and installation work  proposed to  be
     performed  by the Lessee has been installed in the premises), provided
     that  the total of such  periodic payments made  by the Port Authority
     shall  not exceed the Lessee's Finishing  Allowance.  Upon substantial
     completion of the  construction and installation work in  the premises
     to  the  satisfaction  of  the Port  Authority's  Assistant  Director,
     Physical  Facilities, World  Trade  Department, and  his certification
     thereof to the Port  Authority and to  the Lessee, the Port  Authority
     will pay to  the Lessee the  amount so certified  by the Lessee  which
     shall equal the  total of the ten percent (10%)  and five percent (5%)
     deductions made in connection with all previous periodic payments less
     the  amount  of  the  Port  Authority's   periodic  payments  which  a
     preliminary determination  of the Lessee's cost  discloses exceeds the
     Lessee's  Finishing  Allowance  and  less  a  retainage  amount,  such
     retainage amount to  be equal to one  hundred fifty percent  (150%) of
     the amount reasonably established by the Port Authority as the cost of
     fully  completing such work but  nothing herein shall  be construed to
     relieve the Lessee  of its obligation  to expeditiously complete  such

                                       20


     work, such payment to be made within 30 days after such certification.
     Also, upon  full completion of  all the construction  and installation
     work to  be performed by the Lessee pursuant to the provisions of this
     Section  12, the  Lessee shall  supply  to the  Port Authority  a full
     statement   of   the  cost   thereof,   certified   by  a   designated
     representative  of the Lessee.  After examination and approval of such
     certified statement and after such further  examination of the records
     and  books of  account of  the  Lessee relating  to the  costs of  the
     construction  and installation  work as  the  Port Authority  may deem
     reasonable,  the Port  Authority  to promptly  examine such  certified
     statement and such books and records, the Port Authority will promptly
     finally determine the cost of  the construction and installation  work
     performed in the  premises and if  such final determination  discloses
     that  a part of the  Lessee's Finishing Allowance  remains unpaid, the
     Port  Authority will pay  the same to  the Lessee within  fifteen (15)
     days after such  final determination, and  if the final  determination
     discloses  that  the  payments  previously made  exceed  the  Lessee's
     Finishing  Allowance, the Lessee shall repay to the Port Authority the
     amount of such excess within  fifteen (15) days after notice from  the
     Port Authority  of the amount  thereof.  The  Lessee prior to  a final
     determination  of cost shall permit the Port Authority, by its agents,
     employees  and  representatives  at  all  reasonable  times  and  upon
     reasonable  prior notice, to examine  and audit the  records and other
     documentation of the Lessee which pertain to and will substantiate the
     cost.   The Port Authority  agrees that it will  not impose a fee upon
     the Lessee during the Lessee's initial move into the premises for  the
     use  of freight elevators  solely to relocate  the Lessee's furniture,
     equipment,  trade  fixtures and  other  items of  personalty  into the
     premises from  its current space  at 110  William Street and  from the
     Unity space at the Facility.

     Section 13.    Signs

                    Except with  the prior  consent of the  Port Authority,
     the  Lessee   shall  not  erect,   maintain  or  display   any  signs,
     advertising, posters or similar devices at or on the exterior parts of
     the premises  or in  the  premises so  as to  be  visible through  the
     windows,  glass walls or exterior  doors thereof.   The Port Authority
     hereby  agrees that  it will  not withhold  its approval  to  any sign
     submitted to  it for approval by the Lessee to the extent such sign is
     in  accordance with the Tenant  Construction Review Manual.   Upon the
     expiration or  termination of  the letting,  the Lessee  shall remove,
     obliterate or paint out, as the Port Authority may direct, any and all
     signs  and advertising, posters or similar  devices, and in connection
     therewith shall repair any damage resulting from such removal.

     Section 14.    Injury and Damage to Person or Property

                    The Port Authority shall not be liable to the Lessee or
     others  for any personal injury, death or property damage from falling
     material, water,  rain, hail,  snow, gas, steam,  dampness, explosion,
     smoke, radiation, and/or electricity,  whether the same may  leak into
     or fall, issue, or flow from any part of the premises or of  the World
     Trade  Center,  including  without  limitation  thereto  any  utility,
     mechanical,  electrical, communication  or other  systems therein,  or
     from any  other place or quarter  unless said damage, injury  or death
     shall be due to the  negligent acts or willful misconduct of  the Port
     Authority,  its employees  or agents.   Notwithstanding  the foregoing

                                       21


     provisions of this Section,  the Lessee covenants and agrees  that (a)
     any rights of the Lessee to make a claim against the Port Authority as
     contemplated herein  shall  be subject  to the  waiver of  subrogation
     provisions  set  forth  in  the  Section  of  this  Agreement entitled
     "Liability Insurance" and (b) in no event shall the Lessee be entitled
     to  make  a  claim  for consequential,  indirect  or  special  damages
     pursuant to this Section.

     Section 15.    Additional Rent and Charges

                    (a)  If  the Lessee shall fail or refuse to perform any
     of  its  obligations  under  this Agreement,  the  Port  Authority, in
     addition to all other  remedies available to it, shall have  the right
     (but shall  not be obligated to) to perform any of the same after five
     (5) days' notice to the  Lessee of its intention to perform  the same,
     and the expiration of any applicable grace period and the Lessee shall
     pay  the Port Authority's cost thereof on demand.  Notwithstanding the
     foregoing  the  Port  Authority need  not  give  prior  notice of  its
     intention to perform  any of the  same in case  of emergency.   If the
     Port  Authority  has  paid  any  sum  or  sums  or  has  incurred  any
     obligations, expense  or cost which  the Lessee has  agreed to pay  or
     reimburse the Port Authority for, or if the Port Authority is required
     or elects to pay any sum or sums or incurs any obligations, expense or
     cost  by reason of  the failure, neglect  or refusal of  the Lessee to
     perform or  fulfill any one  or more of  the conditions,  covenants or
     agreements contained  in this Agreement, or  as a result of  an act or
     omission  of the Lessee contrary to the said conditions, covenants and
     agreements, including any legal expense or cost in connection with any
     actions or proceeding brought by the Port Authority against the Lessee
     or by third parties against  the Port Authority, the Lessee agrees  to
     pay the sum or sums  so paid or the  expense and the Port  Authority's
     reasonable cost so incurred, including all interest costs, damages and
     penalties,  and the  same may  be  added to  any  installment of  rent
     thereafter due hereunder and each and every part of the  same shall be
     and become additional rent,  recoverable by the Port Authority  in the
     same manner and with like remedies as if  it were originally a part of
     the  basic  rental  as set  forth  in the  Section  of  this Agreement
     entitled "Basic Rental".

                    (b)   "Cost" or "costs"  of the Port  Authority in this
     Agreement shall mean and  include (1) payroll costs including  but not
     limited  to contributions  to the  retirement system,  or the  cost of
     participation in other pension plans or systems, insurance costs, sick
     leave  pay, holiday, vacation, authorized absence  pay or other fringe
     benefits;  (2)   cost  of  materials,  supplies   and  equipment  used
     (including rental  thereof); (3)  reasonable payments  to contractors;
     and (4) any other reasonable direct costs.

     Section 16.    Rights of Entry Reserved

                    (a)   The Port  Authority, by its  officers, employees,
     agents, representatives and  contractors shall have  the right at  all
     times  and  without  notice  during  an  emergency  and during  normal
     business  hours  and  upon  reasonable oral  notice  in  non-emergency
     situations  to enter upon the  premises for the  purpose of inspecting
     the  same,  for  observing  the  performance  by  the  Lessee  of  its
     obligations under this  Agreement, and  for the  doing of  any act  or


                                       22


     thing  which the Port Authority may be  obligated or have the right to
     do under this Agreement or otherwise.

                    (b)  Without limiting  the generality of the foregoing,
     the Port  Authority, by  its officers, employees,  representatives and
     contractors,  shall have  the  right, for  its  own benefit,  for  the
     benefit of the Lessee or for the  benefit of others at the World Trade
     Center, to maintain initially existing and future utility, mechanical,
     electrical, communication and other systems or portions thereof on the
     premises,  and to enter upon  the premises at  all times without prior
     notice during  emergency situations and  at all reasonable  times upon
     reasonable  oral   notice  to  make  such   repairs,  alterations  and
     replacements as may, in  the opinion of the Port Authority,  be deemed
     necessary or advisable and, from time to time, to construct or install
     over,  in,  under or  through the  premises  new lines,  pipes, mains,
     wires,  conduits, equipment and other such provided that to the extent
     feasible  same are  placed  within the  then existing  interior walls,
     floors, existing  columns or  ceilings or else  alongside thereof  and
     boxed in, and the finish  thereof to be consistent with that  existing
     before such work  and the Port  Authority agrees to  consult with  the
     Lessee as to the  most appropriate or feasible place  for construction
     or installation of any item, provided, however, the actual location of
     same  shall  be as  reasonably determined  by  the Port  Authority and
     provided further  that the Port  Authority during performance  of such
     work makes reasonable efforts  to minimize disruption to  the Lessee's
     operations; and to use  the premises for  access to other portions  of
     the World Trade  Center not otherwise conveniently accessible;  and to
     take all material into and upon the premises that may  be required for
     such repairs, alterations  and replacements;  provided, however,  that
     such repair, alteration, replacement, construction or access shall not
     unreasonably interfere with  the use  of the premises  by the  Lessee.
     The  Port  Authority  agrees to  store  only  those  materials in  the
     premises  as are  necessary  to perform  the  work described  in  this
     paragraph (b)  and the Port Authority  further agrees to clean  up the
     premises   to  the  Lessee's  reasonable  satisfaction  subsequent  to
     completion of  the work and  to repair any damage  resulting from such
     work.    The  Port Authority  agrees,  unless  there  is no  practical
     alternative, or unless  required by law, to  perform such maintenance,
     repair, alteration,  replacement, installation  or construction  so as
     not to effectuate a permanent material reduction of the usable footage
     in  the premises.   A material reduction of  the usable square footage
     shall have occurred  if the usable  square footage is reduced  by more
     than  twenty  (20)  usable square  feet,  and  in  the event  of  such
     permanent material  reduction, the  basic rental and  additional basic
     rental shall  be abated as provided  in the Section of  this Agreement
     entitled "Abatement of Rental".

                    (c)  In the event that any property of the Lessee shall
     obstruct  the access of the  Port Authority, its  employees, agents or
     contractors to  any of  the existing  or  future utility,  mechanical,
     electrical, communication  and other systems and  thus shall interfere
     with the inspection, maintenance,  repair or modification of  any such
     system, the  Lessee shall move such property  as requested by the Port
     Authority, in order that  the access may be had to  the system or part
     thereof for its inspection, maintenance, repair or modification.

                    (d)    Nothing  in  this  Section  shall  or  shall  be
     construed  to impose  upon the  Port Authority  any obligations  so to

                                       23


     construct or maintain or to make repairs, replacements, alterations or
     additions, or shall create any liability for any failure so to do, but
     nothing herein shall be  construed to relieve the Port  Authority from
     performance  of obligations  specifically  imposed  elsewhere in  this
     Agreement.   The Lessee  is  and shall  be  in exclusive  control  and
     possession of the  premises and  the Port Authority  shall not in  any
     event be  liable for any  injury or damage to  any property or  to any
     person happening on or about the premises nor for any injury or damage
     to the premises  nor to any  property of  the Lessee or  of any  other
     person  located therein or thereon (other than those occasioned by the
     negligent acts or willful misconduct of the Port Authority).

                    (e)  At  any time and from  time to time during  normal
     business hours within the six (6) months next preceding the expiration
     of  the  letting, the  Port Authority,  by  its agents  and employees,
     whether or not accompanied by prospective  lessees, occupiers or users
     of the premises, shall have the right, upon reasonable advance notice,
     to enter thereon  for the purpose of exhibiting and  viewing all parts
     of  the same.  The  Lessee shall have the right  to accompany the Port
     Authority at  all such  times  and the  Port Authority  agrees to  use
     reasonable efforts to minimize disruption to the Lessee's business.

                    (f)  The exercise of any or all of the foregoing rights
     by the Port Authority or others shall not be  or be construed to be an
     eviction of  the Lessee nor be  made the grounds for  any abatement of
     rental or any claim or demand for damages, consequential or otherwise.

     Section 17.    Condemnation

                    (a)   In  any action  or proceeding  instituted by  any
     governmental or other authorized agency or agencies for the taking for
     a public use of any interest in all or any part of the premises, or in
     case of  any deed, lease or  other conveyance in lieu  thereof (all of
     which are in  this Section referred to as "taking  or conveyance") the
     Lessee shall not be entitled to assert  any claim to any compensation,
     award or part thereof  made or to be  made therein or therefor  or any
     claim  to any  consideration  or  rental  or  any  part  thereof  paid
     therefor, or  to institute any action  or proceeding or  to assert any
     claim  against such agency or  agencies or against  the Port Authority
     for  or on  account of  any such  taking or  conveyance, except  for a
     possible claim to an award  for moving expenses or for trade  fixtures
     owned  and  installed  by the  Lessee,  provided  that  such claim  is
     independent of and in addition to any claim of the  Port Authority and
     provided further  that  the  Port  Authority's award  is  not  thereby
     reduced  or  otherwise adversely  affected,  it  being understood  and
     agreed between the Port Authority and the  Lessee that except for such
     claims the Port Authority shall be entitled to all the compensation or
     awards  made  or to  be made  or paid  and  all such  consideration or
     rentals, free  of any claim or right  of the Lessee.   No taking by or
     delivery to  any governmental authority under this paragraph (a) shall
     be or be construed to be an eviction of the Lessee or be the basis for
     any claim by the Lessee for damages, consequential or otherwise.

                    (b)   In  the event  of a taking  or conveyance  of the
     entire  premises by  any governmental  or other  authorized  agency or
     agencies, then the letting under this  Agreement shall, as of the date
     possession  is taken  from  the  Port  Authority  by  such  agency  or


                                       24


     agencies, cease  and determine in  the same  manner and with  the same
     effect as if the term of the letting had on that date expired.

                    (c)   In the  event of a  taking or  conveyance by  any
     governmental or other authorized agency  or agencies of a part  of the
     premises then the letting  as to such part only shall, as  of the date
     possession thereof is taken from the  Port Authority by such agency or
     agencies, cease and determine, and the rental thereafter to be paid by
     the Lessee  to the Port Authority  shall be abated as  provided in the
     Section  of this  Agreement entitled  "Abatement of  Rental"  from and
     after the date of such taking or conveyance.

                    (d)  In the event that the  taking or conveyance or the
     delivery by the Lessee or taking by the Port Authority pursuant to the
     Section of this  Agreement entitled  "Governmental Compliance"  covers
     fifty percent (50%) or more of the total usable area  of the premises,
     then  the Lessee  and the  Port Authority  shall each  have  an option
     exercisable  by notice given within thirty (30) days after such taking
     or conveyance, to terminate the  letting hereunder, as of the date  of
     such taking, and such termination shall be effective as if the date of
     such taking were the original date of expiration hereof.

                    (e)  In the  event that the taking or conveyance or the
     delivery by the Lessee or taking by the Port Authority pursuant to the
     Section of  this Agreement  entitled "Governmental  Compliance" covers
     ten percent (10%) or more of the total usable area of the premises but
     less  than  fifty  percent  (50%) of  the  total  usable  area of  the
     premises, the Lessee shall have the option exercisable by notice given
     to the  Port Authority within  thirty (30)  days after such  taking or
     delivery  to terminate this  Agreement and the  letting hereunder with
     respect to the  balance of  the premises provided,  however, that  the
     Lessee's  notice to the Port  Authority be accompanied  by a statement
     from a  responsible officer of the Lessee acting in good faith that on
     an  economic  and  operational  basis  the remaining  portion  of  the
     premises cannot be  used by the Lessee or is inadequate for use by the
     Lessee for the operations  described in the Section of  this Agreement
     entitled  "Rights of User by  the Lessee", and  provided, further that
     the Lessee shall not be in default under any term or provision of this
     Agreement  beyond  any  applicable  cure period,  or  under  notice of
     termination from the  Port Authority either on the date  of its giving
     of notice to the Port Authority, or on the effective date.

     Section 18.    Abatement of Rental

                    (a)   In the event  that the  Lessee shall at  any time
     become entitled to an abatement of rent, the basic rental set forth in
     the  Section  of  this  Agreement  entitled  "Basic  Rental"  and  the
     additional  basic  rental set  forth in  Schedule  A attached  to this
     Agreement shall be abated for the period the abatement is in effect by
     the same percentage that the area of the part of the premises the  use
     of which is denied to the Lessee is of the total area of the premises.

                    (b)   For the purposes  of this Section,  the number of
     square  feet contained  in  the premises  or  parts thereof  shall  be
     computed as follows:  By measuring  from the inside  surface of  outer
     building walls to the  surface of the public area side, or of the non-
     exclusive  area side,  as  the case  may  require, of  all  partitions
     separating the space measured from adjoining areas designated for  the

                                       25


     use  of the public or for use by the Lessee in common with others, and
     to  the  center  of  partitions separating  the  space  measured  from
     adjoining  space exclusively used by others; no deduction will be made
     for  columns, partitions,  pilasters or  projections necessary  to the
     building  and   contained  within  the  space   measured.    Permanent
     partitions  enclosing  elevator  shafts,  stairs,  fire-towers, vents,
     pipe-shafts, meter-closets, flues, stacks and any vertical shafts have
     the same relation to the space measured as do outer building walls.

                    (c)  In the  event that during the term  of the letting
     under this Agreement the  Lessee shall be partially evicted  and shall
     remain  in  possession of  the premises  or  the balance  thereof, the
     Lessee  agrees that notwithstanding it might have the right to suspend
     payment of the rent in the absence of this provision, it agrees to pay
     and will pay at the times and  in the manner herein provided, the full
     rent reserved less  only an abatement  thereof computed in  accordance
     with the above.


     Section 19.    Assignment and Sublease

                    (a)  Subject to the provisions  of this Section 19, the
     Lessee  expressly covenants  that  it shall  not  assign, mortgage  or
     encumber this Agreement nor  sublet, or suffer or permit  the premises
     or any  part thereof to be  used by others, without  the prior written
     consent  of  the  Port  Authority  in  each  instance.    A  merger or
     consolidation  shall not be deemed  a violation of  this paragraph (a)
     provided the conditions set  forth in paragraph (a)(5) of  the Section
     of this Agreement entitled "Termination" are met.

                    (b)  Notwithstanding the provisions of paragraph (a) of
     this  Section 19,  the  Lessee shall  have  the right  to  assign this
     agreement and the letting hereunder in  its entirety to, or to  sublet
     to or  to permit  the  use of  desk space  by a  Related Entity;  such
     assignment, subletting or desk  space use to continue only as  long as
     the  proposed assignee maintains the relationship of Related Entity to
     the  Lessee provided that any  such assignee, sublessee  or desk space
     user of  the premises shall use  the premises solely  for the purposes
     set forth in the Section of this Agreement entitled "Rights of User by
     the Lessee" and for no other  purpose whatsoever.  Any such assignment
     pursuant  to  this  paragraph (b)  shall  not  be  effective until  an
     agreement in  the form attached hereto as  Exhibit Y has been executed
     by the  Port Authority, the  Lessee and the  proposed assignee and  no
     such  subleasing pursuant  to  this paragraph  (b) shall  be effective
     until an agreement in the  form attached hereto as Exhibit X  has been
     executed by the Port Authority, the Lessee and the proposed subtenant.
     The  Lessee, and the assignee,  subtenant, or the  desk-space user, as
     the case may be, shall furnish to the Port Authority such information,
     data and documents as may be requested by the Port Authority from time
     to time to substantiate  the relationship between the Lessee  and such
     assignee,  subtenant or desk-space user.  The Port Authority agrees to
     execute the said agreement annexed hereto as Exhibit Y within ten (10)
     business days after receipt of (i) such agreement duly executed by the
     Lessee and the  proposed assignee and (ii) the  documents, information
     and  other  data referred  to  in the  immediately  preceding sentence
     establishing   the  requisite  relationship  between  the  Lessee  and
     proposed  assignee.   The Port  Authority with  respect to  a proposed
     subletting pursuant to this paragraph (b) shall execute the Consent to

                                       26


     Sublease Agreement, or  shall specify  to the Lessee  its reasons  for
     refusing  to  do so,  within a  period of  fifteen (15)  business days
     following  receipt by  the Port  Authority of  (i) a  written sublease
     agreement  fully executed by the  Lessee and a  proposed subtenant and
     (ii) any  other documents, information and data reasonably required by
     the Port Authority with  respect to such subletting.   In addition  to
     the foregoing, the Lessee, subject to the provisions of this paragraph
     (b)  shall have the  right to  assign this  Agreement and  the letting
     hereunder  to a  corporation  into  which  the  Lessee  is  merged  or
     consolidated,  provided the  requirements of  paragraph (a)(5)  of the
     Section  of this  Agreement  entitled "Termination"  are  met and  the
     Lessee shall  also have the right,  subject to the provisions  of this
     paragraph (b) to assign this Agreement and the letting hereunder to an
     entity  to which all or substantially  all of the Lessee's assets have
     been  transferred.   "Related  Entity" as  used  herein shall  mean  a
     corporation,  partnership  or  limited liability  company  which shall
     control, is controlled by  or is under common control with the Lessee.
     "Control", as used  herein, shall mean, in the case  of a corporation,
     legal or beneficial ownership  by one person, firm or  corporation, or
     by a group acting  in concert, of a majority of  the capital stock and
     voting  rights (with power to exercise such rights) of the corporation
     (provided,  however that in connection  with the proposed  use of desk
     space by a  single corporate entity not to exceed  3,000 usable square
     feet,  control  shall mean  ownership  of  not less  than  thirty-five
     percent (35%)  of the capital  stock and voting rights  (with power to
     exercise  such  rights)  of the  corporation  by the  Lessee  or  by a
     corporation  which directly or  indirectly controls or  is directly or
     indirectly  controlled  by the  Lessee or  by  a corporation  which is
     directly  or indirectly  controlled  by a  corporation which  directly
     controls the Lessee, and in the case of such indirect control, each of
     the entities  in the chain between the  Lessee and proposed desk space
     user  shall   directly  control  or  be  directly  controlled  by  the
     immediately adjacent  entity in  such chain),  and in  the  case of  a
     partnership  or limited liability company  it shall mean  the power to
     direct the management and policies of such entity, whether by legal or
     beneficial  ownership,  or  otherwise.    The  Port  Authority  hereby
     consents  to  the use  of  desk  space  in the  premises  by  Unistrat
     Corporation of America, a New York corporation, such use not to exceed
     1,000 usable square feet.

                    (c)  Notwithstanding the provisions of paragraph (a) of
     this Section  19 and in addition to  the rights contained in paragraph
     (b) of  this Section, the  Lessee may, after  the commencement of  the
     letting,  sublet  a  part  or  all  of  the  premises  (but  under  no
     circumstances  shall there be more  subtenants in the  premises at any
     one time pursuant to  the provisions of paragraph (b) of  this Section
     and this paragraph (c), collectively then the whole number obtained by
     dividing 9,000 into the  total number of  rentable square feet in  the
     premises) provided that all of the following conditions precedent  and
     requirements have been met or satisfied:  (1)  Each proposed subtenant
     shall, in the opinion of the Port Authority, be eligible, suitable and
     qualified as a World Trade Center tenant, it being understood that the
     Port  Authority in exercising such opinion will not declare a proposed
     subtenant to be  ineligible unsuitable  or unqualified to  be a  World
     Trade Center tenant  if such proposed subtenant  engages in a  type or
     types of business or operations engaged in or previously engaged in by
     other office tenants at  the World Trade Center whose  eligibility and
     qualifications  were  determined  by  the  Port  Authority  under  the

                                       27


     provisions  of Chapter 5 of Title 17  of the Unconsolidated Law of the
     State of New York strictly on the basis of their functions, activities
     and services in world trade  and commerce; (2)  The rental  payable by
     the  subtenant to  the Lessee  for or  in connection  with its  use or
     occupancy  of the  subleased space shall  be not less  than the rental
     charged  by the Port Authority  for comparable space  for a comparable
     term on the date  of such subletting; (3)  If  the rental rate (taking
     into account all concessions given by the Lessee and all consideration
     payable by the subtenant to  the Lessee for or in connection  with its
     use or occupancy  of the subleased  space) shall be  in excess of  the
     rental rate (taking  into account  all concessions given  by the  Port
     Authority) provided for in this Agreement for the term of the proposed
     subletting,  the Lessee  shall so  notify the  Port Authority  and the
     Lessee subject  to the deductions  set forth in paragraph  (f) of this
     Section 19, shall pay fifty  percent (50%) of such excess to  the Port
     Authority as  received; (4)  The  proposed subtenant is  not a current
     occupant of the World Trade Center and has not been in discussion with
     the Port Authority toward its current  or future occupancy of space in
     the  World Trade Center  within six (6)  months prior  to the Lessee's
     request to the  Port Authority to  enter into the Consent  to Sublease
     Agreement provided the restrictions in this subdivision  (4) shall not
     be applicable if  the proposed subtenant has been notified by the Port
     Authority that  it does not have  available at the World  Trade Center
     for the term sought by the proposed subtenant space comparable in size
     to that being sought by such proposed subtenant; and (5)   The Lessee,
     the  subtenant  and  the Port  Authority  have  executed  the form  of
     agreement entitled  "Consent to  Sublease Agreement", annexed  to this
     Agreement and marked "Exhibit X". 

                    (d)  Execution of  the  Consent to  Sublease  Agreement
     referred to in  paragraph (c) above  by the Port Authority  and return
     thereof to the Lessee  shall constitute the determination referred  to
     in subdivision (1) of paragraph (c)  above.  The Lessee and  subtenant
     shall present in  advance all  documents, information  and other  data
     which the  Port  Authority  may  reasonably require  relating  to  the
     matters covered in subdivisions (1), (2), (3) and (4) of paragraph (c)
     above and the  subtenant shall  supply during the  continuance of  any
     approved subletting such additional or current  documents, information
     or other data as the  Port Authority may from time to  time reasonably
     require.  The  Port Authority  with respect to  a proposed  subletting
     pursuant  to paragraph (c) above shall execute the Consent to Sublease
     Agreement or shall specify to the Lessee its reasons for failing to do
     so, within a period of fifteen (15) business days following receipt by
     the Port Authority of  (i) a written sublease agreement  duly executed
     by the Lessee  and a proposed subtenant and (ii)  any other documents,
     information and data  reasonably required by  the Port Authority  with
     respect to such proposed subletting.

                    (e)  If  the Lessee assigns, sells, conveys, transfers,
     mortgages, pledges or sublets or permits  the use of desk space in the
     premises in violation of paragraphs (a), (b) or (c) of this Section or
     if  the premises are  occupied by anybody  other than  the Lessee, the
     Port  Authority  may  upon  Lessee's  default  collect  rent from  any
     assignee, sublessee, desk-space user  or anyone who claims a  right to
     this  Agreement or  letting or  who occupies  the premises,  and shall
     apply  the net amount collected  to the basic  rental herein reserved;
     and no  such collection shall be deemed a waiver by the Port Authority
     of  the covenants  contained  in paragraphs  (a), (b)  or (c)  of this

                                       28


     Section nor an acceptance by the  Port Authority of any such assignee,
     sublessee,  desk-space user,  claimant or  occupant as  Lessee, nor  a
     release of the Lessee  by the Port Authority from  further performance
     by the  Lessee of  the covenants contained  herein.   The granting  of
     consent  by the Port Authority  to any assignment  or subletting shall
     not be  deemed to operate as a waiver of the requirement for obtaining
     the express prior  written consent of the Port Authority  to any other
     or subsequent assignment or subletting.

                    (f)  If, in connection with any subletting  pursuant to
     the  provisions of  paragraph  (c) hereof  consented  to by  the  Port
     Authority  as provided  herein, the  Lessee (1)  has paid  a brokerage
     commission or commissions (at the customary and usual rates prevailing
     in the City of New  York) to a real estate broker or  brokers licensed
     to do business in the State of New York, which brokerage commission or
     commissions  are  not  reimbursed  to  the Lessee  by  the  subtenant,
     provided such  brokerage commission  or commissions are  actually paid
     for   services  and  are  incurred  solely  in  connection  with  such
     subletting and would not have  been required to have been paid  except
     for such  subletting; or (2) has incurred  any cost for finishing such
     sublet space  to prepare  the same  for  such subtenant  which is  not
     reimbursed to the  Lessee by the  subtenant; or (3)  has granted to  a
     subtenant a basic rental concession for  or in connection with its use
     or occupancy  of the sublease space;  or (4) has incurred  a legal fee
     solely in  connection with the negotiation,  preparation and execution
     of  a  sublease in  connection with  subletting;  or (5)  has incurred
     advertising  and marketing  expenses  solely in  connection with  such
     subletting  or  (6) has  actually  incurred  an  interest  expense  in
     connection with such  subletting, such interest expense  to be allowed
     solely to the extent that the Lessee has  actually borrowed funds from
     a  third party lender and has actually  used such funds solely for the
     expenses incurred in items (1) through (5) herein; (the total of items
     (1), (2), (3), (4), (5)  and (6) being hereinafter referred to  as the
     "subleasing expenses"),  then the  Lessee shall divide  the subleasing
     expenses by the number  of calendar months and the  proportionate part
     of  any partial calendar month  comprising the term  of such sublease,
     and the amount resulting from such division shall be deducted from the
     amount of the rental  or other consideration payable by  the subtenant
     to the Lessee each month which is in excess of the rental rate payable
     by the Lessee to the Port  Authority applicable to the subleased space
     for that month, and fifty percent  (50%) of the balance of such excess
     of the  rental and other consideration shall  be payable by the Lessee
     to the  Port Authority  for  that month.   If  requested  by the  Port
     Authority,  the  Lessee shall  make available  from  time to  time for
     examination by  the  Port Authority  the  Lessee's books  and  records
     relating  to  the receipt  of sublease  rental  and to  the subleasing
     expenses.

                    (g)  In the event the Lessee intends to sublet all or a
     portion of the premises pursuant to the provisions of paragraph (c) of
     this Section 19, and the rental which the Lessee proposes to obtain in
     connection  with the proposed subletting is less than the rental being
     then  charged by  the  Port  Authority  for  comparable  space  for  a
     comparable term,  then notwithstanding the  provisions of  subdivision
     (2) of paragraph (c) of this Section, the Lessee shall  have the right
     to  submit to  the  Port Authority  a statement  of  its Intention  to
     Sublet.  The Intention to Sublet shall be a written statement executed
     by an authorized  officer of  the Lessee setting  forth the  following

                                       29


     information with respect to any future subletting then contemplated by
     the Lessee:

                         (1)  A  description  of  the portion  or
               portions of the premises which the Lessee  intends
               to sublet, including the number of rentable square
               feet  contained therein and the proposed effective
               date of such subletting;

                         (2)  The   amount   of   any   finishing
               allowance, payments to contractors  or the cost of
               any other  work  to be  offered by  the Lessee  to
               prepare the sublet premises for a subtenant;

                         (3)  Rent concessions, if any;

                         (4)  Relocation     contributions    per
               rentable square  foot which the Lessee  intends to
               offer a subtenant;

                         (5)  If the Lessee intends to  utilize a
               real estate broker in connection with any proposed
               subletting, then the  Lessee's good faith estimate
               of the amount of brokerage commissions which would
               be payable  by the  Lessee in connection  with any
               proposed subletting;

                         (6)  Legal    fees,    advertising   and
               marketing expenses and interest expenses which the
               Lessee estimates  in good  faith it will  incur in
               connection with the proposed subletting;

                         (7)  The    term    of   the    proposed
               subletting, it  being understood that the  term of
               any  proposed  subletting  shall  not  exceed  the
               remaining balance of the term of the letting under
               this Agreement less one (1) day.

                    (h)  In the  event the proposed term  of the subletting
     set forth  in the Intention to Sublet is for the entire balance of the
     term of the letting less one (1)  day, then the Port Authority may, by
     notice to the Lessee within twenty (20) business days after receipt of
     such Intention to Sublet,  terminate this Agreement as to  the portion
     of the  premises which the  Lessee intends to  sublet as set  forth in
     such Intention to Sublet,  such termination being hereinafter referred
     to  as  the   "Port  Authority  Termination".    Such  Port  Authority
     Termination  shall be effective as  of the proposed  effective date of
     the subletting  as set forth in  the Intention to Sublet  and from and
     after  the effective  date  of  such  termination  there  shall  be  a
     reduction  of the  annual  basic rental  and  additional basic  rental
     payable, such reduction to be determined as follows:  the annual basic
     rental for  each period set forth  in paragraph (a) of  the Section of
     this Agreement entitled "Rental"  shall be reduced by an  amount equal
     to the product  obtained by  multiplying the annual  basic rental  for
     that  period  by a  fraction,  the  numerator of  which  shall be  the
     aggregate  number of rentable square feet contained in such portion of
     the  premises (the  letting  of which  has  been terminated)  and  the
     denominator  of  which  shall  be  58,783  rentable  square  feet, and

                                       30


     rentable square feet  in the premises  used in calculating  additional
     basic rental pursuant to Schedule A  shall be reduced by the amount of
     rentable  square feet in such portion  of the premises (the letting of
     which shall have been terminated).  In the event the Port Authority is
     entitled to exercise a right of termination with respect to a proposed
     subletting  set forth  in  an Intention  to  Sublet pursuant  to  this
     paragraph (h), but fails  to exercise such right of  termination, then
     the provisions of subdivision (2) of paragraph (c)  of this Section 19
     shall not be applicable  with respect to such proposed  subletting set
     forth  in  such   Intention  to  Sublet  unless  the  actual  proposed
     subletting is in violation of paragraph  (k) below of this Section  19
     in which case the provisions of said subdivision (2) of said paragraph
     (c) shall remain applicable.

                    (i)  In  the  event  that  the  proposed  term  of  the
     subletting  set forth in the Intention to  Sublet is for a period less
     than the  entire  balance  of  the  term of  the  letting  under  this
     Agreement less  one (1) day, then the Port Authority may, by notice to
     the  Lessee within  twenty (20)  business days  after receipt  of such
     Intention to Sublet, sublet from the  Lessee for the term set forth in
     the Intention to Sublet  the portion of the premises  which the Lessee
     intends to  sublet as  set forth  in such  Intention  to Sublet,  such
     subletting  being  hereinafter  referred  to as  the  "Port  Authority
     Subletting".   Such Port Authority Subletting shall be effective as of
     the proposed  effective date of  the subletting  as set  forth in  the
     Intention to Sublet and shall expire on the expiration date set  forth
     in such Intention to Sublet or such earlier date as this Agreement and
     the  letting  hereunder  shall   terminate,  (such  subletting  to  be
     effectuated  by  the  Port  Authority's  notice  without  any  further
     document or agreement required  to be executed by the  parties hereto)
     and from  and after the effective date  of such subletting there shall
     be  a reduction of the annual basic rental and additional basic rental
     payable, such reduction to be determined as follows:  the annual basic
     rental for  each period set forth  in paragraph (a) of  the Section of
     this Agreement entitled "Rental"  shall be reduced by an  amount equal
     to the product  obtained by  multiplying the annual  basic rental  for
     that  period  by  a fraction,  the  numerator of  which  shall  be the
     aggregate  number of  rentable square  feet contained  in such  sublet
     portion  of the premises and the denominator  of which shall be 58,783
     rentable square feet, and rentable square feet in the premises used in
     calculating additional  basic rental pursuant  to Schedule A  shall be
     reduced by the amount of  rentable square feet in such portion  of the
     sublet premises.   In  the event  the  Port Authority  is entitled  to
     exercise a right to sublet with  respect to a proposed subletting  set
     forth in  an Intention to Sublet  pursuant to this paragraph  (i), but
     fails  to  exercise  such right  to  sublet,  then  the provisions  of
     subdivision  (2) of  paragraph  (c) of  this Section  19 shall  not be
     applicable  with respect to such proposed subletting set forth in such
     Intention  to Sublet  unless  the  actual  proposed subletting  is  in
     violation of paragraph (k) below of  this Section 19 in which case the
     provisions  of said subdivision (2) of said paragraph (c) shall remain
     applicable.  The Lessee shall have no rights  whatsoever to the sublet
     premises  during the  term of  any subleasing  hereunder and  shall be
     released from all lease obligations with respect to any portion of the
     premises sublet to the  Port Authority hereunder by the  Lessee during
     the term of  such subletting but nothing herein shall  be construed to
     relieve the  Lessee  from any  obligations under  this Agreement  with
     respect to such sublet space which has accrued prior  to the effective

                                       31


     date of such subletting.  Upon  the expiration date of such subletting
     all of the Lessee's  obligations under this Agreement with  respect to
     such  sublet space shall be applicable, including the payment of basic
     and additional basic rental, with the same force and effect as if such
     subletting had  never occurred.   In  the event that  the term  of the
     subletting  hereunder is  for a  term of  five (5)  years or  less the
     subleased  space  shall  be  made  available  to  the  Lessee  at  the
     expiration  of  the term  of the  sublease  in substantially  the same
     condition,  except  for  reasonable wear  and  tear,  as  it was  made
     available to the Port Authority on the commencement of the sublease to
     the Port Authority.   In the event that the term  of the subletting to
     the  Port Authority is  in excess of  five (5) years,  then the Lessee
     hereby agrees to  accept such sublet  space on  the expiration of  the
     sublease in its then "as is" condition except that  the Port Authority
     will  remove any structural improvements  made during the  term of the
     sublease, will remove  all personalty  therefrom and  will remove  all
     telecommunications wiring and cabling installed during the term of the
     sublease.   The  Port  Authority during  the  term of  any  subletting
     hereunder shall have the exclusive  right to use the sublet space  and
     without limiting the  foregoing may use  the sublet space for  its own
     benefit  or  may  lease the  same  to  third  parties, the  terms  and
     conditions of any third party arrangement to be in the sole discretion
     of  the Port  Authority.    The Lessee  agrees  to  vacate the  sublet
     premises and to  remove all of its  trade fixtures, equipment and  all
     other personalty from the premises on or before the  effective date of
     any subletting hereunder.  The Port Authority will not be obligated to
     provide  any utilities or services  to the sublet  premises during the
     period of the subletting  hereunder and will not  be obligated to  pay
     the Lessee any basic  rental or additional basic rental  in connection
     with the  portion  or portions  of  the premises  sublet to  the  Port
     Authority hereunder.

                    (j)  In the event the Port Authority exercises its Port
     Authority Termination option  pursuant to paragraph  (h) above, or  in
     the  event the Port Authority exercises  its Port Authority Subletting
     option pursuant  to paragraph (i)  above, the Lessee shall  pay to the
     Port  Authority  upon  the  effective  date  of  such  Port  Authority
     Termination or the  effective date of such  Port Authority Subletting,
     as the case may be, the following amounts:  (i) an amount equal to the
     then present value of  the difference between (x) the  amount obtained
     by multiplying the amount of basic rental payable by the Lessee to the
     Port Authority under this Agreement for the premises during the period
     from  the effective  date of  the Port  Authority Termination  or Port
     Authority Subletting, as the case may  be, through the balance of  the
     term of the letting under this Agreement in the case of Port Authority
     Termination or through the  balance of the term of the  Port Authority
     Subletting in the event of a Port Authority Subletting, by a fraction,
     the  numerator of which  shall be the  number of rentable  square feet
     contained in the portion of  the premises proposed to be  subleased as
     set forth  in the  Intention to  Sublet and  the denominator of  which
     shall be  the total number  of rentable  square feet contained  in the
     premises and (y) the  "Total Sublease Basic Rental Amount";  the Total
     Sublease  Basic  Rental  Amount  shall  be  the  product  obtained  by
     multiplying the number of  months from the effective date  of the Port
     Authority  Termination or  the effective  date of  the  Port Authority
     Subletting through the  balance of the term of the  letting under this
     Agreement in the  case of  Port Authority Termination  or through  the
     balance of the term of the Port Authority Subletting, as  the case may

                                       32


     be,  by  the average  monthly basic  rental  amount payable  under the
     proposed sublease described in the Intention to Sublet, such amount to
     be obtained by dividing the number of months in  the proposed sublease
     term described in the Intention to Sublet into the total basic  rental
     payable  under the  proposed  sublease for  the  entire term  of  such
     sublease, and  (ii) an amount  equal to  the sum of  the expenses  set
     forth in  subdivisions (2),  (3), (4),  (5) and  (6) of  paragraph (g)
     above of  this Section  19 which  have been or  which would  have been
     incurred  by  the  Lessee in  connection  with  such  subletting.   In
     determining the present  value of  basic rental for  purposes of  this
     paragraph  (j), an  interest rate  per annum  equal to the  prime rate
     established by Citibank, N.A.  at the time of the  determination shall
     be used.

                    (k)  In the event that the Port Authority shall fail to
     exercise its right to  terminate or sublet pursuant to  paragraphs (h)
     or (i)  above of this Section  19, as the  case may be,  within twenty
     (20)  business days after the Port Authority's receipt of an Intention
     to Sublet  from  the  Lessee, then  the  Lessee,  notwithstanding  the
     provisions of subdivision (2) of paragraph (c) of this Section 19, but
     subject  to the provisions of this paragraph (k), shall have the right
     to  sublet  the premises  or the  portions  thereof described  in said
     Intention  to Sublet pursuant to and in accordance with said paragraph
     (c) provided, however, that if the Lessee thereafter requests the Port
     Authority to enter  into a  Consent to Sublease  Agreement covering  a
     proposed sublease and the  number of rentable square feet  proposed to
     be sublet  is more than ten  percent (10%) larger or  smaller than the
     number of rentable square feet described in the Intention to Sublet or
     that the term  of the subletting is six (6)  months greater or shorter
     than  the term set forth  in the Intention to Sublet  or that on a per
     rentable square foot  basis the present  value of the  rental and  all
     other consideration  payable by the  proposed subtenant over  the term
     for the proposed  subletting less the present  value of any  free rent
     period  and  any  credits,  allowances  or payments  payable  to  such
     proposed  subtenant is  less  than eighty-nine  percent  (89%) of  the
     present value  on a per rentable  square foot basis of  the rental and
     all other consideration  which would have  been payable in  connection
     with  the  subletting covered  by the  Intention  to Sublet,  then the
     provisions  of subdivision (2) of  said paragraph (c)  shall be deemed
     applicable  and the Port Authority  without any liability  on its part
     may  refuse  to enter  into such  Consent  to Sublease  Agreement with
     respect to such proposed subletting.  In determining present value for
     purposes  of this paragraph (k),  an interest rate  per annum equal to
     the  prime rate  of  Citibank, N.A.  in  effect on  the  date of  such
     determination shall be  used.  Notwithstanding anything herein  to the
     contrary, if the Lessee  with respect to an Intention to  Sublet fails
     to request  the Port Authority  to enter  into a  Consent to  Sublease
     within two hundred seventy  (270) days after such Intention  to Sublet
     was submitted  to the Port Authority,  then it shall be  with the same
     force  and effect as if such Intention  to Sublet were never submitted
     to  the  Port  Authority and  the  provisions  of  subdivision (2)  of
     paragraph (c)  of  this Section  19  shall remain  in full  force  and
     effect.

     Section 20.    Termination

                    (a)  If any one or more  of the following events  shall
     occur, that is to say:

                                       33


                         (1)  The Lessee shall  become insolvent, or  shall
               take  the  benefit  of  any  present  or  future  insolvency
               statute, or shall make a general assignment  for the benefit
               of creditors, or file a voluntary petition in bankruptcy  or
               a  petition   or  answer  seeking  an   arrangement  or  its
               reorganization or the readjustment of its indebtedness under
               the  federal  bankruptcy  laws or  under  any  other law  or
               statute of the  United States  or of any  State thereof,  or
               consent  to  the  appointment  of a  receiver,  trustee,  or
               liquidator of all or substantially all its property; or

                         (2)  By  order or  decree  of a  court the  Lessee
               shall  be  adjudged  bankrupt  or  an  order  shall  be made
               approving  a petition filed by  any of the  creditors or, if
               the Lessee is a  corporation, by any of the  stockholders of
               the Lessee, seeking its  reorganization or the  readjustment
               of  its indebtedness  under the  federal bankruptcy  laws or
               under any  law or  statute of  the United  States or  of any
               State thereof; or

                         (3)  A  petition  under any  part  of the  federal
               bankruptcy  laws or  an action under  any present  or future
               insolvency law  or statute shall be filed against the Lessee
               and shall not be dismissed within ninety (90) days after the
               filing thereof; or

                         (4)  Except  as  specifically  permitted   in  the
               Section   of   this  Agreement   entitled   "Assignment  and
               Sublease", the  letting hereunder or the  interest or estate
               of the Lessee under this Agreement shall  be transferred to,
               pass to or devolve  upon, by operation of law  or otherwise,
               any other person, firm or corporation; or

                         (5)  The  Lessee, if a corporation, shall, without
               the prior consent of the Port Authority, become  a possessor
               or merged corporation in a merger, a constituent corporation
               in a consolidation, or  a corporation in dissolution, unless
               the corporation resulting from such merger  or consolidation
               has a financial  standing as  of the date  of the merger  or
               consolidation at least  as good  as that of  the Lessee,  by
               which is meant that  its ratio of current assets  to current
               liabilities  and its  net worth  shall each  be at  least as
               favorable as that of the Lessee; or 

                         (6)  The Lessee  is  a partnership,  and the  said
               partnership shall be dissolved  as the result of any  act or
               omission of its partners or any of them, or  by operation of
               law or the order or decree of any court having jurisdiction,
               or for any other reason whatsoever; or

                         (7)  By or pursuant to,  or under authority of any
               legislative act, resolution or rule, or  any order or decree
               of any  court or governmental  board, agency  or officer,  a
               receiver, trustee,  or liquidator shall  take possession  or
               control  of all  or substantially  all the  property  of the
               Lessee,  or  any execution  or  attachment  shall be  issued
               against  the  Lessee  or  any  of  its  property,  whereupon
               possession of  the premises shall be taken  by someone other

                                       34


               than the Lessee,  and any such  possession or control  shall
               continue in effect for a period of sixty (60) days; or

                         (8)  Any   lien  is  filed  against  the  premises
               because of  any act  or omission  of the Lessee  and is  not
               removed or  bonded within forty-five (45)  days after notice
               thereof from the Port Authority; or

                         (9)  If  this Agreement shall  require a guarantor
               of one  or  more  of the  Lessee's  obligations  under  this
               Agreement and  any of the events  described in subparagraphs
               (1), (2), (3) or (7) above shall occur to or with respect to
               the  guarantor (whether or not  they shall also  occur to or
               with respect to the Lessee); or

                         (10) The Lessee  shall fail duly and punctually to
               pay the  rentals  or  to  make any  other  payment  required
               hereunder  when due to  the Port Authority  and such failure
               shall continue for a period of ten (10)  days after the Port
               Authority shall have given  the Lessee a statement therefor;
               or

                         (11) The Lessee  shall fail  to keep, perform  and
               observe each and every other promise, covenant and agreement
               set  forth in  this  Agreement  on  its  part  to  be  kept,
               performed,  or  observed,  within  thirty  (30)  days  after
               receipt  of  notice  of  default thereunder  from  the  Port
               Authority   (except  where  fulfillment  of  its  obligation
               requires  activity over  a period  of time,  and the  Lessee
               shall have commenced to perform whatever may be required for
               fulfillment within thirty (30)  days after receipt of notice
               and   continues   diligently   such    performance   without
               interruption except for causes beyond its control); 

     then upon the  occurrence of any such event or  at any time thereafter
     during the continuance  thereof, the  Port Authority may  by five  (5)
     days'  notice terminate the letting,  such termination to be effective
     upon the date specified in such notice.  Such right of termination and
     the exercise thereof shall be and operate as a conditional limitation.

                    (b)  If any  of the events enumerated  in paragraph (a)
     of this  Section shall occur prior to the Prior Entry Date, the Lessee
     shall not be entitled to enter into possession of the premises and the
     Port Authority  upon the occurrence of  any such event or  at any time
     thereafter during  the continuance thereof by  twenty-four (24) hours'
     notice may cancel  the interest  of the Lessee  under this  Agreement,
     such  cancellation to  be effective  upon the  date specified  in such
     notice.

                    (c)  No acceptance by  the Port  Authority of  rentals,
     fees, charges or other payments  in whole or in part for any period or
     periods after a default in any of the  terms, covenants and conditions
     to be  performed, kept  or observed  by the Lessee  shall be  deemed a
     waiver of any right on the part of the Port Authority to terminate the
     letting.

                    (d)  No waiver by the Port  Authority or the Lessee  of
     any default  on the  part  of the  other party  to  this Agreement  in

                                       35


     performance of any of the terms,  covenants or conditions hereof to be
     performed, kept or observed by such  party shall be or be construed to
     be  a waiver  by the  Port  Authority or  the Lessee  of any  other or
     subsequent  default in performance of any of the said terms, covenants
     and conditions.

                    (e)  The rights of termination described above shall be
     in  addition to  any  other rights  of  termination provided  in  this
     Agreement and in  addition to any  rights and remedies  that the  Port
     Authority would have at law or in equity consequent upon any breach of
     this Agreement by the Lessee, and  the exercise by the Port  Authority
     of any  right of termination shall  be without prejudice to  any other
     such rights and remedies.

                    (f)  The  Lessee hereby  waives its  right to  trial by
     jury  in  any  summary proceeding  or  action  that  may hereafter  be
     instituted by the Port  Authority against the Lessee in respect of the
     premises or in any action that may be brought by the Port Authority to
     recover  rent, damages, or other  sums payable hereunder.   The Lessee
     shall  not  interpose  any  claims as  counterclaims  in  any  summary
     proceeding or action for non-payment of rental which may be brought by
     the Port Authority unless such claims would be deemed waived if not so
     interposed.

     Section 21.    Right of Re-entry

                    The Port Authority shall,  as an additional remedy upon
     the giving  of a notice of  termination as provided in  the Section of
     this Agreement entitled "Termination", have  the right to re-enter the
     premises and every part thereof upon the effective date of termination
     without  further notice  of  any  kind,  and  may  regain  and  resume
     possession  either with or without  the institution of  summary or any
     other  legal proceedings or otherwise.  Such re-entry, or regaining or
     resumption of possession,  however, shall  not in  any manner  affect,
     alter or diminish  any of  the obligations  of the  Lessee under  this
     Agreement,   and  shall  in  no  event  constitute  an  acceptance  of
     surrender.

     Section 22.    Survival of the Obligations of the Lessee

                    (a)   In  the event  that the  letting shall  have been
     terminated in accordance with  a notice of termination as  provided in
     the Section of this Agreement entitled  "Termination", or the interest
     of the  Lessee cancelled  pursuant thereto, or  in the event  that the
     Port Authority has  re-entered, regained or resumed possession  of the
     premises  in accordance  with the  provisions of  the Section  of this
     Agreement entitled  "Right of  Re-entry", all  the obligations  of the
     Lessee  under  this  Agreement   shall  survive  such  termination  or
     cancellation,  re-entry,  regaining or  resumption  of possession  and
     shall  remain in  full force  and  effect for  the full  term of  this
     Agreement,  and the amount or  amounts of damages  or deficiency shall
     become due and payable,  as more specifically stated in  paragraph (b)
     below, to the Port Authority  to the same extent, at the same  time or
     times and in the  same manner as if no  termination, cancellation, re-
     entry, regaining or resumption of possession had taken place.

                    (b)  Immediately  upon any termination or  cancellation
     pursuant to  the Section of this Agreement  entitled "Termination", or

                                       36


     upon any re-entry, regaining or resumption of possession in accordance
     with the Section of this Agreement entitled "Right of Re-entry", there
     shall become due and payable  by the Lessee to the Port  Authority, in
     addition to rental accrued prior to the effective date of termination,
     without notice or demand and as damages, the sum of the following:

                     (1)  subject to the provisions of paragraph (c) below,
               an  amount  equal to  the then  present  value of  all basic
               rental provided for  in this Agreement for the  entire term,
               following  the effective date  of termination, as originally
               fixed in the Section of  this Agreement entitled "Term" less
               the  amount thereof which may have been actually paid by the
               Lessee;

                     (2)   the  amount  of all  other unfulfilled  monetary
               obligations of  the Lessee  under this Agreement,  including
               without limitation thereto, all sums constituting additional
               rental  hereunder and the cost  to and expenses  of the Port
               Authority for fulfilling all other obligations of the Lessee
               which would  have accrued or  matured during the  balance of
               the term  or  on the  expiration  date originally  fixed  or
               within a stated time after expiration or termination; and

                     (3)  an amount  equal to the cost to and  the expenses
               of the  Port Authority  in connection with  the termination,
               cancellation,   regaining   possession  and   restoring  and
               reletting  the premises (provided that as to any costs which
               would have  been customarily incurred by  the Port Authority
               upon  the  original  expiration  date of  the  letting  with
               respect  to any  reletting, such  as  brokerage commissions,
               finishing allowances  and  rent concessions  the portion  of
               such  costs to be included herein shall be equivalent to the
               product obtained by multiplying such costs by a fraction the
               numerator  of which  shall be  the number  of months  in the
               letting hereunder  subsequent to  termination and up  to the
               original expiration  date and  the denominator shall  be the
               number of months  in the  term of any  such reletting),  the
               Port Authority's  legal  expenses and  costs  including  the
               costs to the Port Authority of its in-house counsel, and the
               Port  Authority's  cost  and    expenses  for  the  care and
               maintenance of  the premises  during any period  of vacancy,
               and any  brokerage fees  and commissions in  connection with
               any reletting.

                    (c)  The Port Authority may at any time bring an action
     to recover all the damages as set forth above not previously recovered
     in  separate actions, or it may  bring separate actions to recover the
     items of damages  set forth in subparagraphs (2)  and (3) of paragraph
     (b)  above and separate actions  periodically to recover  from time to
     time only such portion of the damages set forth in subparagraph (1) of
     paragraph (b) above as would  have accrued as rental up to the time of
     the  action if there had been no  termination or cancellation.  In any
     such action the Lessee shall be allowed a credit against  its survived
     damages  obligations equal  to the  amounts  which the  Port Authority
     shall  have actually received from  any tenant, licensee, permittee or
     other occupier of the premises or a part thereof during the period for
     which  damages  are sought,  and if  recovery is  sought for  a period
     subsequent to the  date of suit  a credit equal  to the market  rental

                                       37


     value  of the premises during  such period (discounted  to reflect the
     then present value thereof).   If at the time of  such action the Port
     Authority  pursuant  to  an  arms  length  transaction has  relet  the
     premises, the rental for the premises obtained through such  reletting
     shall be deemed to be  the market rental value  of the premises or  be
     deemed to  be the basis for computing such market rental value if less
     than the entire  premises were relet.   In no  event shall any  credit
     allowed  to the Lessee  against its damages for  any period exceed the
     then present  value of the basic rental  which would have been payable
     under   this  Agreement  during  such   period  if  a  termination  or
     cancellation had not  taken place.   In determining  present value  of
     rental an interest rate of 6% per annum shall be used.

     Section 23.    Reletting by the Port Authority

                    The  Port Authority,  upon termination  or cancellation
     pursuant  to the Section of this  Agreement entitled "Termination", or
     upon any re-entry,  regaining or resumption of possession  pursuant to
     the Section of this Agreement entitled "Right of Re-entry", may occupy
     the premises  or may relet the  premises, and shall have  the right to
     permit  any person, firm or corporation to enter upon the premises and
     use  the same.   The  Port Authority  may grant  free rental  or other
     concessions and such reletting may be  of part only of the premises or
     of the premises or a part thereof together with other space, and for a
     period of  time the same as or different  from the balance of the term
     hereunder  remaining, and on terms and conditions and for purposes the
     same as or different from those set forth in this Agreement.  The Port
     Authority shall also, upon termination or cancellation pursuant to the
     Section  of this  Agreement entitled  "Termination", or  upon its  re-
     entry, regaining or resumption of  possession pursuant to the  Section
     of  this Agreement  entitled "Right  of Re-entry",  have the  right to
     repair  or  to  make structural  or  other  changes  in the  premises,
     including  changes which alter the  character of the  premises and the
     suitability  thereof  for  the  purposes  of  the  Lessee  under  this
     Agreement,  without affecting, altering or diminishing the obligations
     of the Lessee hereunder.   In the event either of any  reletting or of
     any actual  use and occupancy by  the Port Authority or  a third party
     whose occupancy  is not  pursuant to  an arms-length  transaction (the
     mere right to use and occupy not being sufficient however) there shall
     be  credited to  the  account  of  the  Lessee  against  its  survived
     obligations hereunder  any net  amount remaining after  deducting from
     the amount actually  received from any lessee,  licensee, permittee or
     other  occupier as the rental or fee  for the use of the said premises
     or portion  thereof during the balance  of the letting as  the same is
     originally  stated in  this Agreement  (it being  understood, however,
     that in computing such net amount remaining  to the Port Authority any
     rent concessions or finishing allowances granted by the Port Authority
     or brokerage commissions paid by the Port Authority in connection with
     any reletting shall  be amortized  on a straight-line  basis over  the
     entire  term  of  the reletting),  or  from  the market  value  of the
     occupancy of such portion of  the premises as the Port Authority  or a
     third party occupying not  pursuant to an arms-length  transaction may
     during  such period actually use  and occupy, all  expenses, costs and
     disbursements incurred  or paid  by the Port  Authority in  connection
     therewith.  No such reletting or such use and occupancy shall be or be
     construed to be an acceptance of a surrender.



                                       38


     Section 24.    Waiver of Redemption

                    The  Lessee  hereby  waives   any  and  all  rights  of
     redemption, granted by or under any present or future law, arising  in
     the event it is evicted or dispossessed for any cause, or in the event
     the  Port Authority obtains or  retains possession of  the premises in
     any lawful manner.

     Section 25.    Remedies and Suits Against the Lessee

                    All remedies provided in this Agreement shall be deemed
     cumulative and  additional and  not in  lieu of  or exclusive  of each
     other or of any other remedy available to the Port Authority at law or
     in  equity.   In the  event of  a breach or  threatened breach  by the
     Lessee  of  any  term,  covenant,   condition  or  provision  of  this
     Agreement, the Port Authority  shall have the right of  injunction and
     the right to invoke any other remedy allowed by law or in equity as if
     termination,  re-entry, summary  proceedings  and  any other  specific
     remedies   including   without  limitation   thereto,   indemnity  and
     reimbursement,  were not  mentioned  herein, and  neither the  mention
     thereof nor the pursuance or exercise or failure to pursue or exercise
     any right or  remedy shall preclude the  pursuance or exercise  of any
     other right or remedy.


     Section 26.    Surrender

                    (a)  The Lessee  covenants  and  agrees  to  yield  and
     deliver  peaceably to the Port Authority possession of the premises on
     the date of the cessation of the letting, whether such cessation be by
     termination, expiration  or otherwise,  promptly and in  the condition
     required  by paragraph (a) of  the Section of  this Agreement entitled
     "Construction by the Lessee".

                    (b)  Unless the same  are required for  the performance
     by the Lessee of its obligations hereunder, the Lessee  shall have the
     right at any time during the letting to remove from the premises, and,
     on or before  the expiration  or earlier termination  of the  letting,
     shall so remove its equipment,  removable fixtures and other  personal
     property,   and  all  property  of  third  persons  for  which  it  is
     responsible, repairing all  damages caused  by such removal.   If  the
     Lessee shall fail to remove such property on or before the termination
     or expiration of the  letting, the Port Authority shall  have the same
     rights  with respect  to  such property  as  it has  in  the event  of
     casualty under paragraph (d) of the Section of this Agreement entitled
     "Casualty".

     Section 27.    Acceptance of Surrender of Lease

                    No  agreement of  surrender  or to  accept a  surrender
     shall be  valid unless and until  the same shall have  been reduced to
     writing  and signed by the duly authorized representatives of the Port
     Authority and of  the Lessee.   Except as expressly  provided in  this
     Section, neither  the doing of,  nor any  omission to do,  any act  or
     thing,  by  any of  the  officers,  agents or  employees  of the  Port
     Authority, shall be deemed an acceptance of a surrender of the letting
     or of this Agreement.  Without limiting  the foregoing, no employee or
     officer  of the Port Authority shall  be authorized to accept the keys

                                       39


     of  the premises prior to the expiration  date of the letting as fixed
     in the Section  of this Agreement entitled  "Term" and no delivery  of
     the  keys by  the  Lessee  shall  constitute  a  termination  of  this
     Agreement or acceptance of surrender.

     Section 28.    Brokerage

                    The  Lessee represents  and  warrants that  it has  not
     dealt or had  any contacts or  dealings with any broker  in connection
     with  the negotiation and execution  of this Agreement  or the letting
     hereunder  except  Edward   S.  Gordon  Company,  Inc.,   a  New  York
     corporation  having an office and  place of business  at 111 Broadway,
     New  York, New York 10006, and  that there is no  broker with whom the
     Lessee has dealt or  had contacts or  dealings with who  is or may  be
     entitled  to  be  paid a  commission  or fee  in  connection  with the
     negotiation and execution of  this Agreement or the  letting hereunder
     except Edward S. Gordon  Company, Inc.  The Lessee shall indemnify and
     save harmless  the Port Authority of  and from any and  all claims for
     commission, brokerage or fees which have been or which may  be made by
     any  and all persons, firms or corporations whatsoever for services in
     connection with the negotiation and execution of this Agreement or the
     letting hereunder with  whom the Lessee has  dealt or had  contacts or
     dealings with except for a claim  of Edward S. Gordon Company, Inc. if
     the said claim is made  in accordance with the terms of  the agreement
     between the Port Authority and Edward S. Gordon Company, Inc. dated as
     of January 10, 1995.

     Section 29.    Notices

                    (a)  Notices,   requests,  permissions,   consents  and
     approvals given  or required to be  given to or by  either party under
     this  Agreement, shall  not  be effective  unless  they are  given  in
     writing, and all  such notices  and requests shall  be (i)  personally
     delivered  to the party or a duly designated officer or representative
     of such party; or (ii) delivered  to the office of such party, officer
     or  representative during regular business hours; or (iii) if directed
     to the  Lessee, delivered at the  premises at any time  from and after
     the  date the Lessee commences business operations in the premises; or
     (iv)  forwarded to such party, officer or representative at the office
     or  residence address  by registered  or certified  mail.   The Lessee
     shall designate an office within the  Port of New York District and an
     officer or representative whose  regular place of business is  at such
     office.   Except  as may  be specifically  provided elsewhere  in this
     Agreement,  the  Port  Authority   hereby  designates  its   Executive
     Director, and the Lessee designates the person named as representative
     on   the  first   page  hereof   as  their   respective   officers  or
     representatives upon whom  notices and  requests may be  served.   The
     Port  Authority designates its office  at One World  Trade Center, New
     York, New  York 10048 as its  office where notice and  requests may be
     served.  The Lessee up until the date it commences business operations
     in the premises designates its office at 110 William Street, New York,
     New  York   10038 and from  and after  the date  it commences business
     operations in the premises designates its office at the address stated
     on  the first page hereof, as its respective offices where notices and
     requests  may be served.  It is  hereby understood and agreed that the
     Port Authority and  the Lessee by prior notice to  the other from time
     to  time  may  designate  officers  and  representatives  and  offices


                                       40


     different than  those  named  herein for  the  purposes  of  receiving
     notices and requests.

                    (b)  If any  notice is delivered, such  notice shall be
     deemed  to have been  given or made  on the date delivered  and if any
     notice is  mailed, such notice shall  be deemed to have  been given or
     made on the second day after the day the notice is so mailed.

     Section 30.    Payments

                    (a)  All  payments  required  of  the  Lessee  by  this
     Agreement shall  be  mailed to the Port  Authority of New York and New
     Jersey,  P. O. Box 17309, Newark, New  Jersey 07194, or to such office
     or address as may be substituted therefor.

                    (b)  No payment by  the Lessee or  receipt by the  Port
     Authority of a lesser rental amount than that which is due and payable
     under the  provisions of this  Agreement at  the time of  such payment
     shall  be deemed to be other than a payment on account of the earliest
     rental then  due, nor shall any endorsement  or statement on any check
     or in any letter accompanying any check or payment be deemed an accord
     and  satisfaction, and  the Port  Authority may  accept such  check or
     payment  without prejudicing  in  any way  its  right to  recover  the
     balance of  such rental or to pursue any other remedy provided in this
     Agreement or  by law.  No payment by  the Port Authority or receipt by
     the Lessee of a lesser amount than that which is due and payable under
     the provisions  of this Agreement at the time of such payment shall be
     or be  deemed to  be other than  a payment on  account, nor  shall any
     endorsement  or statement or any  check or in  any letter accompanying
     any  check or payment  be deemed an  accord and  satisfaction, and the
     Lessee may accept such check or payment without prejudicing in any way
     its right to recover  the balance of any such amount or  to pursue any
     other remedy provided in this Agreement or by law.



     Section 31.    Late Charges; Monetary and Non-Monetary Disputes

                    (a)  If  the  Lessee  should  fail to  pay  any  amount
     required  under  this  Agreement  when  due  to  the  Port  Authority,
     including without limitation any  payment of basic or other  rental or
     any payment of utility or other charges, then, in such event, the Port
     Authority may impose (by  statement, bill or otherwise) a  late charge
     with respect to  each such unpaid amount  for each late  charge period
     (hereinbelow  described)  during the  entirety  of  which such  amount
     remains unpaid, each such late charge not to exceed an amount equal to
     eight-tenths of one percent of such unpaid amount for each late charge
     period.  There shall be twenty-four late charge periods on a  calendar
     year basis; each late charge period shall be  for a period of at least
     fifteen (15) calendar days except one late charge period each calendar
     year may  be for  a period  of less  than fifteen  (but not less  than
     thirteen)  calendar  days.     Each  late  charge  shall   be  payable
     immediately  upon demand  made  at  any  time  therefor  by  the  Port
     Authority.   No  acceptance by  the Port Authority  of payment  of any
     unpaid amount  or of any unpaid  late charge amount shall  be deemed a
     waiver  of the  right of  the Port  Authority to  payment of  any late
     charge  or late charges payable  under the provisions  of this Section
     with respect to  such unpaid amount.   Each late  charge shall be  and

                                       41


     become  additional rent, recoverable by the Port Authority in the same
     manner and with like  remedies as if it were originally  a part of the
     rental  as set forth in the  Section of this Agreement entitled "Basic
     Rental".   Nothing in this Section is  intended to, or shall be deemed
     to, affect, alter, modify or diminish in any way (i) any rights of the
     Port Authority under this  Agreement, including without limitation the
     Port Authority's rights  set forth  in the Section  of this  Agreement
     entitled "Termination"  or (ii) any  obligations of  the Lessee  under
     this Agreement.  If the  precise amount of any payment required  to be
     made by the Lessee under this Agreement cannot be known to the Lessee,
     such payment shall  not be deemed due to the  Port Authority until ten
     (10) days after  the Port Authority notifies the Lessee  of the amount
     of  such payment.  In the event  that any late charge imposed pursuant
     to  this Section shall exceed a  legal maximum applicable to such late
     charge, then, in such event, each such late charge payable under  this
     Agreement shall be payable instead at such legal maximum.

                    (b)  In the event  that the Lessee shall in  good faith
     dispute  the amount of any charge or  other amount claimed by the Port
     Authority as due and payable to it by the Lessee under this Agreement,
     and the  Lessee within fifteen  (15) days after  notice from the  Port
     Authority  that such  amount  is due  and  payable notifies  the  Port
     Authority of the amount it is disputing and the reason it is disputing
     same, then the Lessee  may withhold solely the portion of  such charge
     or amount  in dispute (and shall  pay the remainder of  such charge or
     amount to  the Port Authority)  and for a  period of thirty  (30) days
     following such  notice, the failure of the Lessee to pay such withheld
     amount  shall not constitute a default, an  event of default or ground
     for  termination giving the Port Authority the right to terminate this
     Agreement and the letting  hereunder pursuant to paragraph (a)  of the
     Section of this Agreement entitled "Termination" or exercise any other
     rights  or remedies under this  Agreement, nor shall  a late charge be
     imposed  on any  such withheld  amount pursuant  to the  provisions of
     paragraph (a)  of this Section, in  each case so long  as the withheld
     amount shall be the subject of  a bona fide dispute between the Lessee
     and the Port Authority,  provided, that nothing in this  paragraph (b)
     shall permit or be deemed to permit the Lessee to dispute and withhold
     any payment  of basic rental or any portion  thereof or all or part of
     any other charge or amount,  the amount of which is specified  in this
     Agreement.  The  Lessee and the Port Authority will  promptly meet and
     make  good faith efforts  to resolve  any such  dispute, and  from and
     after the resolution of such  dispute, if any amount shall be  due and
     owing to the Port  Authority, the provisions of paragraph  (a) of this
     Section  (including, without  limitation, the  fifteen (15)  day grace
     period  permitted to  the Lessee  prior to  the imposition  of a  late
     charge)  shall  be applicable  thereto.   If the  Lessee and  the Port
     Authority shall be unable  to resolve such dispute within  thirty (30)
     days after the Lessee  notifies the Port  Authority of the reason  for
     the dispute, the Port Authority shall have the right to terminate this
     Agreement  and the  letting  hereunder or  exercise  any other  remedy
     available to it  under this Agreement or otherwise, whether  in law or
     in  equity.  The  Port Authority covenants  that if  the Lessee should
     serve an effective and timely Notice of Claim upon the  Port Authority
     with  respect to such dispute  pursuant to and  in accordance with the
     provisions of Section  7101 et. seq. of the Unconsolidated Laws of the
     State  of New  York,  within ten  (10) business  days  after the  Port
     Authority  shall have served upon the Lessee a notice terminating this
     Agreement  and  the  letting  hereunder,  then  and  subject  to   the

                                       42


     provisions of paragraph (c) below, the effective date set forth in the
     Port Authority's Notice of Termination shall be deemed postponed until
     five  (5) business days  after the claim  set forth in  such Notice of
     Claim or  any ensuing  legal action with  respect to  that dispute  is
     resolved,  and if  such resolution  determines that  the Lessee  is in
     default of the monetary  obligation disputed by the Lessee  under this
     Agreement,  the  Port  Authority   shall  not  commence  a  "holdover"
     proceeding or any other proceeding to evict the Lessee on the basis of
     such  dispute until  on  or after  the  day following  such  postponed
     effective date of  termination.  If  such resolution should  determine
     that the Lessee is not in default of said disputed monetary obligation
     under this  Agreement, or if the  Lessee shall have paid  the disputed
     monetary  obligation within such five (5) business day period, then in
     either  case such Notice of Termination shall be deemed withdrawn with
     the same force  and effect  as if  it had never  been served.   It  is
     expressly understood that nothing contained herein  shall be deemed to
     waive any rights of the Port Authority under the provisions of Section
     7101  et. seq. of  the Unconsolidated Laws  of the State  of New York.
     Any  such Notice of  Claim shall  be served  and prosecuted  solely in
     accordance  with  the  provisions of  Section  7101  et.  seq. of  the
     Unconsolidated  Laws of the State  of New York,  and the Lessee hereby
     covenants  and agrees that it shall diligently prosecute the Notice of
     Claim and  any ensuing legal  action with  respect to that  dispute to
     resolution.

                    (c)  If the Lessee should serve an effective and timely
     Notice  of Claim  upon the Port  Authority with respect  to a monetary
     dispute referred to  in paragraph  (b) above of  this Section 31,  the
     Port Authority notwithstanding  service of such Notice  of Claim shall
     have the right to request  by notice to the Lessee within  thirty (30)
     days after service of such notice of claim that such  monetary dispute
     be  resolved in  accordance  with the  Expedited Procedures  provision
     (Rules  53 through 57  in the May  1, 1992 edition)  of the Commercial
     Arbitration Rules of the  American Arbitration Association and  if the
     Port Authority  does so request arbitration,  then simultaneously upon
     receipt by the Lessee of the Port Authority's notice,  the said Notice
     of  Claim shall be deemed withdrawn by  the Lessee with the same force
     and effect as if it  had never been served  by the Lessee on the  Port
     Authority,  but the effective date  set forth in  the Port Authority's
     Notice  of Termination  referred to  in paragraph  (b) above  shall be
     deemed postponed until  five (5)  business days after  the dispute  is
     resolved by arbitration.  If such resolution by arbitration determines
     that the Lessee is  in default of the monetary  obligation disputed by
     the  Lessee  hereunder,  the  Port  Authority  shall  not  commence  a
     "holdover" proceeding or any  other proceeding to evict the  Lessee on
     the basis of  such dispute until  on or after  the day following  such
     postponed effective  date of termination.   If such  resolution should
     determine that the Lessee is not in default of such described monetary
     obligation under this Agreement, or if the Lessee within such five (5)
     business day  period shall have paid the disputed monetary obligation,
     then in each case such Notice of Termination shall be deemed withdrawn
     with the same force and  effect as if it  had never been served.   All
     costs of arbitration pursuant to this paragraph (c) shall be  borne by
     the  unsuccessful party (and if both parties are partially successful,
     such costs shall  be apportioned  between the Port  Authority and  the
     Lessee in inverse  proportion to the amount by which  such decision is
     favorable to each party).


                                       43


                    (d)  In the event  that the Port Authority shall send a
     notice to the Lessee claiming that it is in default of any of its non-
     monetary  obligations under  this  Agreement, other  than any  default
     which (i) affects life and safety, or (ii) affects any building system
     which directly affects other tenants in the Building, or (iii) affects
     the ability of  the Port  Authority to provide  essential services  to
     other tenants of the Building, and the Lessee, in good faith, disputes
     that it is in default  of such obligations, then, provided the  Lessee
     shall notify the  Port Authority of  the basis for the  dispute within
     ten  (10) business  days  after its  receipt  of the  notice,  and, if
     applicable and feasible, shall comply with or perform any non-disputed
     portions or aspects of such disputed obligation, then, for a period of
     twenty-five (25) days following such notice, the failure of the Lessee
     to comply with or perform the disputed obligation shall not constitute
     a default, an event  of default or  ground for termination giving  the
     Port Authority the right  to terminate this Agreement and  the letting
     hereunder pursuant to paragraph  (a) of the Section of  this Agreement
     entitled  "Termination" or exercise any other rights or remedies under
     this Agreement.  The Lessee and the Port  Authority will promptly meet
     and make  good faith efforts to  resolve any such dispute,  and if the
     Lessee  and the Port Authority shall be unable to resolve such dispute
     within  twenty-five (25)  days  after  the  Lessee notifies  the  Port
     Authority of the basis for the  dispute, the Port Authority shall have
     the right to  terminate this  Agreement and the  letting hereunder  or
     exercise  any other  right  or  remedy  available  to  it  under  this
     Agreement, or  otherwise,  whether in  law  or in  equity.   The  Port
     Authority covenants that if  the Lessee should serve an  effective and
     timely Notice of Claim  upon the Port Authority  with respect to  such
     dispute pursuant to and  in accordance with the provisions  of Section
     7101  et. seq. of  the Unconsolidated Laws  of the State  of New York,
     within  ten (10)  business days  after the  Port Authority  shall have
     served upon the  Lessee a  notice terminating this  Agreement and  the
     letting  hereunder,  the   effective  date  set  forth   in  the  Port
     Authority's Notice of Termination shall be  deemed postponed until ten
     (10) business days  after the claim set forth in  such Notice of Claim
     or any ensuing legal action with respect to that  dispute is resolved,
     and if such resolution determines that the Lessee is in default of the
     obligation  disputed by  the  Lessee under  this  Agreement, the  Port
     Authority shall  not  commence a  "holdover" proceeding  or any  other
     proceeding  to evict the Lessee on the  basis of such dispute until on
     or  after  the  day   following  such  postponed  effective  date   of
     termination,  and   the  postponement   of  such  effective   date  of
     termination shall continue as long as the Lessee commences to cure the
     default giving rise to the dispute  within said ten (10) business  day
     period and diligently  prosecutes said  cure to completion.   If  such
     resolution should determine that the Lessee is  not in default of said
     disputed  obligation under this Agreement, or if the Lessee shall have
     commenced to cure  the default giving rise to  the dispute within such
     ten (10)  business day  period  and shall  thereafter have  diligently
     prosecuted such cure to completion, then in either case such Notice of
     Termination shall be deemed  withdrawn with the same force  and effect
     as  if it  had never  been served.   It  is expressly  understood that
     nothing contained herein  shall be deemed  to waive any rights  of the
     Port  Authority under the provisions  of Section 7101  et. seq. of the
     Unconsolidated Laws of  the State of New  York, and the  Lessee hereby
     covenants  and agrees that it shall diligently prosecute the Notice of
     Claim and any  ensuing legal action  with respect  to that dispute  to
     resolution.

     other legal entity.

                    (c)  This Agreement does not constitute the Lessee, the

     failure, delay or interruption in performing its obligations hereunder
     due to causes or conditions beyond the control of  the Port Authority.

                    (c)  In  the  event that  any  failure  to provide  the
     Lessee with access to  the premises in accordance with the  Section of
     this Agreement entitled  "Ingress and Egress",  or to supply  elevator
     service to the premises,  or to supply  other services which the  Port
     Authority  has  agreed  to supply  pursuant  to  the  Section of  this
     Agreement entitled  "Services and  Utilities" or  the Section of  this
     Agreement entitled  "Additional Services"  (whether or not  excused by
     this  Section 37,  paragraph  (h) of  the  Section of  this  Agreement
     entitled "Services and Utilities" or other provisions hereof), renders
     uninhabitable  one  or  more portions  of  the  premises  so that  the
     Lessee's  operations  under the  Section  of  this Agreement  entitled
     "Rights  of User by the Lessee" cannot reasonably be conducted therein
     and such failure  of service is  not the  result of the  fault of  the
     Lessee, its officers, employees, agents or contractors, and the Lessee
     shall  give  notice  to the  Port  Authority of  such  fact  and shall
     thereafter vacate and not use the said portion of the premises for the
     Lessee's  operations  permitted  by  the  Section  of  this  Agreement
     entitled  "Rights  of User  by the  Lessee"  for five  (5) consecutive
     business days,  then thereafter,  while such vacant  and uninhabitable
     condition and non use shall continue, the Lessee shall be  entitled to
     an  abatement  of the  basic rental  and  the additional  basic rental
     hereunder (as provided for  in the Section of this  Agreement entitled
     "Abatement of  Rental") solely as  to the  portion of the  premises so
     rendered vacant, uninhabitable  and which is  unused provided that  if
     such  vacant  and uninhabitable  condition  and  non-use shall  as  to
     fifteen  percent (15%)  or more  of  the rentable  square feet  in the
     premises continue for two hundred seventy (270) consecutive days, then
     the Lessee shall have  the right to terminate  this agreement and  the
     letting  hereunder in its entirety  by giving thirty  (30) days' prior
     notice to the Port Authority provided such notice is given to the Port
     Authority no later than the thirtieth  (30th) day from the end of such
     two  hundred seventy (270) consecutive day period and provided further
     that such  non-use, vacant  and uninhabitable  condition does not  end
     prior to the  date the Lessee gives the Port  Authority such notice of
     termination.   Termination by the Lessee pursuant to the provisions of
     this paragraph (c) shall  be with the same force and effect  as if the

                                       47


     effective date of termination  stated in the Lessee's notice  were the
     date set forth in this Agreement as the expiration date of the letting
     hereunder.
      
     Section 38.    Premises

                    The Lessee acknowledges that it has not relied upon any
     representation   or   statement  of   the   Port   Authority  or   its
     Commissioners,  officers, employees or agents as to the suitability of
     the  premises for  the operations  permitted on  the premises  by this
     Agreement.  The Lessee agrees that  no portion of the premises will be
     used initially  or  at any  time  during the  letting  which is  in  a
     condition  unsafe  or  improper  for  the  conduct  of  the   Lessee's
     operations  hereunder so that there is possibility of injury or damage
     to life  or property.  For all purposes of this Agreement the premises
     hereunder (notwithstanding any statement  elsewhere in this  Agreement
     of any rule  for the measurement of the area  thereof) shall be deemed
     to include  all of the enclosing  partitions, and the interior  of the
     adjacent exterior building walls including glass therein.

     Section 39.    Governmental Compliance

                    In the event that all or any portion of the premises is
     required by the  Port Authority to comply  with any present or  future
     governmental law,  rule, regulation, requirement, order  or direction,
     the Port Authority  shall give the Lessee notice that  all or any such
     portion of  the premises is so  required and the  Lessee shall deliver
     all or  any such  portion  of the  premises so  required  on the  date
     specified in such  notice and, if the Lessee does  not so deliver, the
     Port Authority may take the same.  No such taking or delivery shall be
     or be construed to be  an eviction of the  Lessee or a breach of  this
     Agreement.   In  the  event that  the  Lessee has  received  a  notice
     hereunder it  shall deliver all or any such portion of the premises so
     required  in the  same condition  as that  required hereunder  for the
     delivery of  the premises  on the  cessation of the  letting.   In the
     event of  the taking or  delivery of all the  premises, this Agreement
     and the letting hereunder shall on the day of such  taking or delivery
     cease and expire as if that day were the date originally stated herein
     for the  expiration of this Agreement; and, in the event of the taking
     or delivery of any portion of the premises, then, from  and after such
     taking or delivery,  such portion of the premises shall  cease to be a
     part of  the premises hereunder.   There shall be an  abatement of the
     rental in the event of any such taking or delivery of a portion of the
     premises  as  provided  in  the  Section  of  this Agreement  entitled
     "Abatement of Rental".

     Section 40.    Services and Utilities

                    (a)  Subject to  all the  terms and provisions  of this
     Agreement, the  Port Authority will furnish  without additional charge
     to the Lessee the following:

                         (1)  During    normal    business   hours    heat,
               ventilation  and   air  cooling  in   accordance  with   the
               specifications  set forth  in  Schedule  D attached  hereto,
               subject to the provisions of paragraph (b) of the Section of

                                       48

               services in the portion of the premises shown on Exhibit A-1
               as described in Schedule B-1 attached hereto and hereby made
               a part hereof.

                         (3)  Passenger  elevator service  to the
               premises  on business days  during normal business
               hours, which  service  shall consist  of not  less
               than three  (3) elevator  cars available  from the
               lobby of the South Tower Building to each floor of
               the   premises  and  one  passenger  elevator  car
               available  from  the  lobby  of  the  South  Tower
               Building to each floor  of the premises during all
               other  times; one  freight  elevator  serving  the
               premises and  the  entire Building  in  which  the
               premises  are located  on call  on a  "first come,
               first served" basis on business days during normal
               business hours  and on a reservation  "first come,
               first served" basis during hours other than normal
               business hours;

                         (4)  Access to the premises 24 hours per
               day, 365 days per year throughout the term of this
               Agreement, subject to the Lessee's compliance with
               the  Rules and  Regulations, and  with such  other
               reasonable rules, regulations and procedures which
               may be imposed  by the Port Authority,  including,
               without  limitation,  regulations  and  procedures
               establishing reasonable security checks.

                    (b)  Unless  the premises  contain toilet  and washroom
     facilities,  the  Port  Authority shall,  without  additional  charge,
     furnish non-exclusive toilet and washroom facilities for the employees
     of the Lessee.  The  Port Authority agrees to furnish hot  and potable
     cold  water for sanitary purposes  in the public  bathrooms located in
     the  Lessee's premises  or located  of multitenanted  floors on  which
     portions of the Lessee's premises are located.

                    (c)  Subject   to  all   the   terms,  provisions   and
     conditions of  paragraphs (f), (g), (h) and (i) of this Section 40 and
     to  the extent  that  the Lessee's  consumption  does not  exceed  the
     capacity of  feeders, risers  or wiring in  the building of  which the
     premises  is a  part (it  being the  Lessee's sole  responsibility for
     designing and constructing distribution systems for the premises), the
     Port Authority  will supply to  the existing electric  closets serving
     the  premises on each floor  of the premises  for use by  the Lessee 7
     watts per rentable  square foot of  electrical capacity (exclusive  of
     electricity  required for  HVAC and  core facilities)  as follows:   3
     watts at  120/208 and 4  watts at  277/465 provided that  if the  Port
     Authority  pursuant  to its  comprehensive  plan for  the  World Trade
     Center  increases the  electrical  capacity to  10 watts  per rentable
     square foot  in the first zone  of the South Tower  Building, then the
     Port  Authority upon written request  from the Lessee  will provide 10
     watts  per rentable square foot  of electrical capacity  to the Lessee
     but nothing  herein  shall in  any  way be  construed  to in  any  way
     obligate the Port Authority to increase the electrical capacity in the

                                       49


     first zone of the South Tower Building or elsewhere at the World Trade
     Center.  Electricity furnished to the Lessee  shall be used solely for
     illumination by  which  is meant  the  energizing of  fluorescent  and
     incandescent  bulbs (to  be supplied,  paid for  and installed  by the
     Lessee)  and for the operation  of such office  machines and equipment
     (including  computers) as are customarily utilized in an office of the
     type  described in the Section  of this Agreement  entitled "Rights of
     User  by  the Lessee",  and  the  Lessee shall  pay  for  the same  in
     accordance with the following  provisions of this paragraph (c).   The
     quantity of all electricity  supplied to the Lessee shall  be measured
     by  a meter  or  meters to  be  furnished and  installed  by the  Port
     Authority  at  its  cost  and  expense  for  that  purpose  (it  being
     understood that the wiring and all other electrical work in connection
     with such  metering shall be performed  by the Lessee at  its cost and
     expense), and  in the event any  such meter fails to  record such, the
     quantity of  electricity so supplied during any period that a meter is
     out  of service  will be  considered to  be the  same as  the quantity
     supplied during a like period immediately before such interruption and
     if  there is no like period immediately before such interruption, then
     it  shall be  a like period  immediately after  such disruption.   The
     quantity  of such electricity  shall be paid  for by the  Lessee in an
     amount  equal  to 100%  of  the  rates (including  the  fuel or  other
     adjustment  factor, if  any)  which  the  Lessee,  under  the  service
     classification then applicable to the Lessee, would be required to pay
     for  the same quantity of electricity to  be used for the same purpose
     under the same conditions if the Lessee had purchased such electricity
     directly from  the  public  utility  company  supplying  the  same  to
     commercial  buildings in the vicinity of the  World Trade Center.  The
     Lessee shall pay the cost of such consumption and demand for each such
     billing  period to the  Port Authority  upon demand  therefor (billing
     period  hereunder to  be the same  as that  established by  the public
     utility company  supplying electricity to commercial  buildings in the
     vicinity  of the  World Trade  Center), and  the same shall  be deemed
     additional  rental  collectible  in  the  same manner  and  with  like
     remedies as if it were a  part of the basic rental reserved hereunder.
     Notwithstanding  that   the  Port  Authority  has   agreed  to  supply
     electricity  to the  Lessee,  the Port  Authority  shall be  under  no
     obligation to provide or  continue such service if the  Port Authority
     is  prevented   by  law,  agreement  or   otherwise  from  submetering
     electricity as hereinabove set forth or  elects not to so submeter the
     same,  provided that unless prevented  by law the  Port Authority will
     not  discontinue the  supply of  electricity to  the Lessee  unless it
     discontinues such supply to all non-governmental entities at the World
     Trade  Center whose  premises are  in excess  of one  hundred thousand
     (100,000) rentable square feet.  In  the event the Port Authority does
     so  discontinue the supply of  electricity, the Lessee  shall make all
     arrangements and conversions necessary to obtain electricity  directly
     from the public utility company supplying electricity in the vicinity.
     Also,  in  such  event,  the  Lessee  shall  perform  the construction
     necessary for  such conversion, and if despite such discontinuance the
     Port Authority was  not prevented by law  from submetering electricity
     as hereinabove set forth, then  the Port Authority shall grant to  the
     Lessee a credit  against its rental  payments next becoming due  in an
     amount  equal  to the  Lessee's  reasonable  cost  of performing  such
     necessary  construction  provided, however  that  if the  term  of the
     letting expires prior  to full  application of such  credit, then  the
     Port Authority will promptly pay the Lessee such portion of the credit
     as  has not been applied against rental.  If any lines or equipment of

                                       50


     the Port  Authority are with  the consent  of the Port  Authority used
     subsequent  to  such  conversion,  the  Port  Authority  may  make  an
     appropriate  charge  therefor to  the Lessee  based  on its  costs and
     expenses for the said lines and equipment.  

                    (d)  If the  Lessee, in accordance with  the Section of
     this  Agreement entitled  "Construction by  the Lessee"  or otherwise,
     erects any  partitions or makes  any improvements which  stop, hinder,
     obstruct or  interfere with the cooling  of the air or  the heating of
     the premises, or if the Lessee shall fail to close and keep closed the
     window  coverings  when the  sun  is  shining on  the  windows of  the
     premises,  then  no  such  action  by  the  Lessee  shall  impose  any
     obligations on  the Port Authority to install  facilities, fixtures or
     equipment for  air-cooling or for heating additional to those existing
     or presently contemplated  or to  increase the capacity  or output  of
     initially existing  facilities, equipment  or fixtures and  the Lessee
     shall not  in any  such event  be relieved of  any of  its obligations
     hereunder  because a  comfortable  temperature is  not maintained  but
     nothing herein shall be construed to relieve the Port Authority of its
     obligation  to  provide  heating,   ventilation  and  air  cooling  in
     accordance  with the  specifications  set forth  in  Schedule D.    No
     consent given by the Port Authority  to the erection of partitions  or
     the  making  of  any improvements  shall  be  or  be  deemed to  be  a
     representation  that the  work  consented to  will  not stop,  hinder,
     obstruct or interfere with either the cooling of the air or heating of
     the premises or any portion thereof.  It is hereby understood  further
     that  the installation  by the  Lessee of  any equipment  which itself
     requires air cooling  or which requires  additional quantities of  air
     cooling  at  the  portion of  the  premises  where  such equipment  is
     installed or the concentration in any portion of  the premises of such
     a number  of people  so  as to  require additional  quantities of  air
     cooling,  shall not  impose any  obligation on  the Port  Authority to
     install facilities, fixtures and  equipment for air cooling additional
     to those initially existing, or to  increase the capacity or output of
     initially existing  facilities, equipment  or fixtures and  the Lessee
     shall not  in any such  event be  relieved of any  of its  obligations
     hereunder.

                    (e)  The Lessee  shall keep  closed all  entrance doors
     and  all windows in the premises except  that doors may be opened when
     required for ingress or egress.  The Lessee  shall not otherwise waste
     or dissipate the air cooling or heating services.

                    (f)  If   any  federal,   state,  municipal   or  other
     governmental body, authority or agency or any public utility assesses,
     levies, imposes, makes  or increases any  charge, fee  or rent on  the
     Port Authority for any service, system or utility now or in the future
     supplied to  or available to the premises or to any occupants or users
     thereof  or to the structure or building  of which the premises form a
     part (including  but not limited to  any sewer rent or  charge for the
     use  of sewer systems),  the Lessee shall,  at the option  of the Port
     Authority exercised at any time and from time to time by notice to the
     Lessee, pay, in accordance with said notice, such charge, fee  or rent
     or  increase thereof  (or the  portion thereof  allocated by  the Port
     Authority to the premises or the Lessee's operations hereunder) either
     directly  to  the governmental  body, authority  or  agency or  to the
     public utility  or directly to the Port Authority.  No charge, fee, or
     rent or  increase shall be  imposed upon the  Lessee pursuant  to this

                                       51


     paragraph  (f) to  the extent  any such  is included  as an  Operating
     Expense for purposes of Schedule A.

                    (g)  The  Port  Authority  shall   have  the  right  to
     discontinue temporarily the supply  of any of the above  services when
     necessary or desirable in the reasonable opinion of the Port Authority
     in  order to make any repairs, alterations, changes or improvements in
     the premises or elsewhere in the World Trade  Center including but not
     limited to all systems for the supply of services.  The Port Authority
     will  give  reasonable  advance   notice,  when  practicable,  of  the
     anticipated   commencement,   duration   and  notice   of   any   such
     interruption.    The  Port  Authority  will  proceed  with  reasonable
     diligence to eliminate the interruption.

                    (h)  Subject to the provisions  of paragraph (c) of the
     Section of this Agreement entitled "Force Majeure", no failure, delay,
     interruption or reduction in any service or services shall be or shall
     be construed to be an eviction of the Lessee, shall be grounds for any
     diminution or  abatement of  the rentals  payable hereunder, or  shall
     constitute  grounds  for   any  claim  by  the   Lessee  for  damages,
     consequential  or otherwise, unless due  to the negligent  acts of the
     Port Authority, its employees or agents.

                    (i)  The Port Authority shall be under no obligation to
     supply any service  or services if  and to the  extent and during  any
     period that the  supplying of any such service or  services or the use
     of any component necessary therefor shall be prohibited or rationed by
     any federal,  state or  municipal law, rule,  regulation, requirement,
     order or  direction and if the  Port Authority deems it  in the public
     interest to comply therewith, even though such  law, rule, regulation,
     requirement,  order  or direction  may not  be  mandatory on  the Port
     Authority as a public agency.

                    (j)  (i)  In such kitchen facilities as may be referred
     to  in paragraph  (e)  of  the  Section  of  this  Agreement  entitled
     "Responsibilities  of  the Lessee"  and as  are  approved by  the Port
     Authority for installation  in the premises pursuant to the provisions
     of the Section of this Agreement entitled "Construction by the Lessee"
     and subject to the provisions  of paragraphs (f), (g), (h) and  (i) of
     this Section  41, the Port  Authority will  supply to the  Lessee cold
     water,  of the  character  furnished by  the  municipality or  utility
     company  supplying  the same  in  the vicinity  and  hot  water, at  a
     temperature of approximately 140 F,  both in reasonable quantities for
     use  by  the  Lessee  through  such fixtures  and  outlets  as  may be
     installed by the  Lessee pursuant to the provisions of  the Section of
     this Agreement  entitled  "Construction  by the  Lessee".    The  Port
     Authority will measure the quantities of such cold water and hot water
     supplied to the Lessee by meters to be installed by the Port Authority
     for the purpose.  The  Lessee shall pay to the Port  Authority for the
     cold and hot  water as billed by the Port Authority  from time to time
     at  the following rates:   (1) cold  water, at the  rate of Thirty-six
     Dollars and Sixty-eight Cents ($36.68) per thousand cubic feet and (2)
     hot  water  at the  rate of  Sixty-two  Dollars and  Seventy-one Cents
     ($62.71)  per  thousand  cubic feet;  the  charges  to  be subject  to
     increase  in rates charged the Port Authority as provided in paragraph
     (f) of this Section  40 and with respect to the charge for metered hot
     water  the  same shall  also  be subject  to increase  as  provided in
     subparagraph (ii) of  this paragraph (j)  below.  Notwithstanding  the

                                       52


     foregoing, the Port Authority will not impose a charge upon the Lessee
     for  cold and hot water  used in conjunction  with drinking fountains,
     dryer  units,  dishwashers,  kitchen  sinks, kitchen  ice  makers  and
     existing public restrooms located in the premises.

                         (ii) The charge for metered hot water provided for
     in subparagraph  (i) above of this  paragraph (j) shall be  subject to
     increase from  time to time as follows:   "Wage rate' as  used in this
     paragraph  shall mean the hourly straight time wage rate for Engineers
     as that  wage rate  is established  from  time to  time by  collective
     bargaining  agreement  between  the  Realty Advisory  Board  on  Labor
     Relations, Incorporated,  acting on behalf of  various building owners
     and Local 94 of  the International Union of Operating  Engineers, AFL-
     CIO,  and "basic  wage rate"  shall mean  the wage  rate in  effect on
     January 1, 1994.  From  and after each wage rate established  from and
     after  the commencement  date of the  letting, the Lessee  shall pay a
     charge for  metered hot water in  addition to the charge  set forth in
     subparagraph (i)  above,  such  additional  charge  to  be  an  amount
     computed by multiplying  the charge  for metered hot  water stated  in
     that  subparagraph  by the  percentage increase  in  the wage  rate so
     established over the basic  wage rate.  If either  the Realty Advisory
     Board  on  Labor   Relations,  Incorporated,  or   Local  94  of   the
     International Union  of Operating  Engineers, AFL-CIO, shall  cease to
     exist  or  a  collective  bargaining   agreement  shall  cease  to  be
     negotiated  between  the Realty  Advisory  Board  on Labor  Relations,
     Incorporated, and  Local 94 of  the International  Union of  Operating
     Engineers,  AFL-CIO, then  the  wage rate  to  be used  for  computing
     increases in  the said  charge shall  be the  wage rate for  Engineers
     established under  such collective  bargaining agreements as  the Port
     Authority shall select.  If  the job classification "Engineers"  shall
     be renamed  or abolished, then the Port  Authority will select the job
     classification  performing substantially  the same  labor function  as
     Engineers  and the  wage rate  of the  job classification  so selected
     shall be used in computing increases in the charge provided herein.

                    (k)  The Port Authority  shall have  no obligations  or
     responsibility  with respect  to the  performance of  any  services or
     providing, supplying or furnishing  to the Lessee of any  utilities or
     services whatsoever except as expressly provided in this Agreement.

     Section 41.    Liability Insurance

                    (a)  The Lessee shall not  do or permit to be  done any
     act or thing upon the premises or at the World Trade Center which will
     invalidate  or  conflict  with  any insurance  policies  covering  the
     premises  or any part thereof, or the  World Trade Center, or any part
     thereof, which, in the  reasonable opinion of the Port  Authority, may
     constitute an extra-hazardous condition, so  as to increase the  risks
     normally attendant upon the operations contemplated by the Section  of
     this Agreement entitled "Rights of User by the Lessee", and the Lessee
     shall  promptly observe, comply with and execute the provisions of any
     and all present and future rules and regulations, requirements, orders
     and directions  of the National  Fire Protection  Association and  the
     Insurance Services Office, Inc. and of any other board or organization
     exercising or which  may exercise similar functions, which may pertain
     or apply  to the  operations of  the Lessee on  the premises,  and the
     Lessee shall, subject to and in accordance  with the provisions of the
     Section of this Agreement entitled "Construction by the Lessee",  make

                                       53


     any  and all improvements, alterations or repairs of the premises that
     may be  required at any time  hereafter by any such  present or future
     rule,  regulation,  requirement,  order  or  direction, provided  such
     improvements,  alterations  or  repairs  are  not  required  generally
     throughout  the building in which the premises are located unless such
     general requirement results from the Lessee's particular manner of use
     of or its  particular operations in the premises which  are not common
     to  other tenants in  the building in which  the premises are located,
     and  if by reason of  any failure on the part  of the Lessee to comply
     with  the provisions  of  this Agreement  any  insurance rate  on  the
     premises or any part thereof or on the World Trade Center or any  part
     thereof, shall  at any time be higher than it otherwise would be, then
     the  Lessee shall pay to the Port  Authority, as an item of additional
     rental, that part of all insurance premiums paid by the Port Authority
     which shall have been charged because of such violation or failure  by
     the Lessee, but no such payment shall relieve the Lessee  of its other
     obligations under this paragraph.

                    (b)  (i)  The Lessee  in its own name  as assured shall
     secure and  keep in full force  and effect throughout the  term of the
     letting under this Agreement, at Lessee's sole cost and expense, (a) a
     policy  of  comprehensive  general  liability  insurance  including  a
     contractual liability endorsement for  such coverage as may reasonably
     be stipulated from  time to time  by the  Port Authority covering  the
     Lessee's operations hereunder which  shall be effective throughout the
     letting  under this  Agreement and  shall initially  be in  a combined
     single  limit of  not less  than $2,000,000  for liability  for bodily
     injury,  for wrongful death and  for property damage  arising from any
     one occurrence; and  (b) a fire or other casualty  policy insuring the
     full replacement value of all construction, installation and finishing
     work  performed by  the  Lessee  in  the  premises  and  the  Lessee's
     furniture, trade fixtures, equipment and other personal property, such
     insurance to include a replacement cost endorsement, with a deductible
     of no  more than $1,000 against loss  or damage by fire  and theft and
     such other risks or  hazards as are insurable under present  or future
     forms of "All Risk" insurance policies.

                         (ii) The  Port Authority shall  be included  as an
     additional  insured in any  policy of liability  insurance required by
     this Section.  The Lessee shall have the right to  insure and maintain
     the  insurance  coverages  set forth  in  this  Section  under blanket
     insurance policies covering  the premises and other  space occupied by
     Lessee, if  any,  so  long as  such  blanket policies  comply  in  all
     respects with  the insurance provisions  set forth in  this Agreement;
     provided that upon request, Lessee shall deliver to the Port Authority
     a  certificate  of Lessee's  insurer  evidencing the  portion  of such
     blanket policy of insurance allocated to the premises.

                         (iii)As to any insurance required by this Section,
     a  certified  copy  of each  of  the  policies  or  a  certificate  or
     certificates evidencing  the existence thereof (including all required
     endorsements and evidence  of the waivers  of subrogation required  by
     paragraph (c) of this Section), or binders, shall be delivered  to the
     Port  Authority within twenty (20) days prior to the commencement date
     of the  letting hereunder.  In  the event any binder  is delivered, it
     shall be replaced within  thirty (30) days by a  certificate including
     said  endorsements and such waiver of subrogation.  Within thirty (30)
     days  after request of the Port Authority  made at any time during the

                                       54


     term of  the letting under this  Agreement the Lessee shall  deliver a
     certified copy of the policy to the Port Authority.  Each such copy or
     certificate  shall contain endorsements that (a) the policy may not be
     cancelled, terminated, changed or modified without giving at least ten
     (10)  days written advance notice  thereof to the  Port Authority; (b)
     the insurer  shall not,  without obtaining express  advance permission
     from  the General  Counsel of  the Port  Authority, raise  any defense
     involving in any way the jurisdiction of the  tribunal over the person
     of  the  Port  Authority, the  immunity  of  the  Port Authority,  its
     Commissioners, officers, agents or employees, the  governmental nature
     of the Port  Authority or  the provisions of  any statutes  respecting
     suits  against  the Port  Authority; and  (c)  Lessee shall  be solely
     responsible for the payment  of premiums therefor notwithstanding that
     the  Port Authority  is  named as  an additional  insured.   A renewal
     certificate  shall be delivered to the Port Authority at least fifteen
     (15) days prior to the expiration date of each expiring policy, except
     for  any policy expiring after the date  of expiration of the letting,
     provided  that within  thirty  (30) days  after  request by  the  Port
     Authority  the Lessee shall deliver  a certified copy  of such renewal
     policy to  the Port  Authority.  If  at any time  any of  the policies
     shall be  or become unsatisfactory to the Port Authority as to form or
     substance, or if any of the carriers issuing such policies shall be or
     become unsatisfactory to the Port Authority, the Lessee shall promptly
     obtain a new and satisfactory policy in  replacement.  A carrier shall
     be deemed satisfactory to the Port Authority if it has and maintains a
     rating by  Best's Insurance Reports  or any  successor publication  of
     comparable standing  of "A" or better  or the then  equivalent of such
     rating.    The Port  Authority  will not  find  a policy  issued  by a
     satisfactory  carrier to  be unsatisfactory  as to  form or  substance
     unless   it  contains   an   exclusion  not   generally  included   in
     Comprehensive General  Liability policies which landlords  in the City
     of New York owning comparable first class office buildings at the time
     of such determination  require to be maintained  by tenants conducting
     operations similar to those conducted by the Lessee in the premises.

                    (c)  Each party shall include  in each of its insurance
     policies  covering  loss, damage  or  destruction  by  fire  or  other
     casualty (insuring  the World  Trade Center  and the  Port Authority's
     property  therein in the case of the  Port Authority, and insuring the
     Lessee's property required to be insured by Lessee under paragraph (b)
     above in the  case of the Lessee)  a waiver of the  insurer's right of
     subrogation  against  the other  party or,  if  such waiver  should be
     unobtainable  or unenforceable,  (i)  an express  agreement that  such
     policy  shall  not be  invalidated if  the  insured waives  before the
     casualty the right  of recovery  against any party  responsible for  a
     casualty  covered  by  such  policies,  or  (ii)  any  other  form  of
     permission for the release of the other party.  If any party hereto is
     unable  to  obtain  such   waiver,  agreement  or  permission  without
     additional charge, then  such party shall  be relieved from  providing
     such waiver, agreement or  permission unless the other party  shall so
     elect and shall pay the carrier's additional charge therefor.

                    (d)  Each party  hereby releases  the other  party with
     respect to any claim (including a claim for negligence) which it might
     otherwise have against the other party for loss, damage or destruction
     with   respect  to  its  property  (including  business  interruption)
     occurring during the term of the letting under this Agreement and with
     respect and to  the extent to  which it is  insured under a  policy or

                                       55


     policies  containing a waiver of  subrogation or permission to release
     liability as provided in paragraph (c) above.

                    (e)  Nothing contained  in said  paragraphs (c)  or (d)
     above of this Section shall be  deemed to impose upon either party any
     duty to  procure or maintain any of the kinds of insurance referred to
     therein except as  otherwise required in this Section.   If the Lessee
     shall  fail  to  maintain insurance  in  effect  as  required in  this
     Section, the release by the Lessee set forth in paragraph (d) above of
     this Section shall be in  full force and effect to the  same extent as
     if such required  insurance (containing a waiver  of subrogation) were
     in effect.  Notwithstanding anything to the contrary contained in this
     Agreement,  the carrying of insurance by the Lessee in compliance with
     this  Section shall not modify,  reduce, limit or  impair the Lessee's
     obligations and liability under the Section of this Agreement entitled
     "Indemnity".

                    (f)  At the  time of  the execution of  this Agreement,
     there  is  in  effect  a policy  of  insurance  under  which  the Port
     Authority  is  the insured  covering damage  to  the premises  and the
     Facility  having a deductible of  One Hundred Thousand  Dollars and No
     Cents  ($100,000.00)  and  containing  an endorsement  permitting  the
     release described in paragraph (c) above of this Section 41.  The Port
     Authority  does  not represent  or warrant  that  it will  continue to
     maintain such insurance, provided, however, that in the event that the
     Port  Authority shall no longer maintain  insurance covering damage to
     the  premises or the Facility, or shall maintain such insurance having
     a  higher  deductible amount,  in each  case  so long  as  the release
     described  in  said paragraph  (c)  above  shall remain  available  on
     commercially  reasonable  terms  to   owners  of  first-class   office
     buildings in the  City of New  York with more than  1,000,000 rentable
     square  feet, the obligation of the Lessee set forth in paragraphs (b)
     and (c) of  the Section  of this Agreement  entitled "Maintenance  and
     Repair" shall  be released to  the extent  that such loss  exceeds One
     Hundred  Thousand  Dollars  and   No  Cents  ($100,000.00),  it  being
     expressly  understood and  agreed that  the  maximum liability  of the
     Lessee  under such circumstances in the event of damage or destruction
     to  the Facility,  or  any portion  thereof,  shall be  $100,000  with
     respect  to  any single  occurrence.   Nothing  herein shall  limit or
     affect the Lessee's liability with respect to such $100,000 portion of
     such loss, and with respect to such $100,000 portion of such loss, the
     provisions  of paragraph (b) of the Section of this Agreement entitled
     "Maintenance  and Repair" and of this paragraph (f) shall control, and
     nothing  in  this paragraph  (f) shall  limit  or affect  the Lessee's
     liability  which  it may  otherwise  have  under  this Agreement  with
     respect to damage  not insurable under the  New York standard form  of
     fire  insurance policy  or  the New  York  standard form  of  extended
     coverage endorsement.

     will  submit  to  the   Port  Authority  in  writing  a   fixed  price
     (hereinafter called the "Public Corridor Price") for  which the Lessee
     will agree to perform such  Public Corridor Work.  The  Port Authority
     within ten (10) business  days after receipt of such price will advise
     the Lessee whether or not  it accepts the Lessee's price.  If the Port
     Authority  does not accept the Lessee's price, the Port Authority will

     the work described  in this paragraph (e), such payment  to be made in
     accordance with paragraph (f) below.

                    (f)  Upon  completion   of  the  work  by   the  Lessee
     described  in  paragraphs (c),  (d) and  (e)  above, the  Lessee shall
     deliver  to the Port Authority  a certificate signed  by an authorized
     officer  of  the  Lessee and  a  certificate  signed  by the  Lessee's
     architect  or  professional   engineer,  each   certifying  that   the
     construction  and installation work has been completed and in the case
     of the Public Bathroom Work and  Public Corridor Work that it has been
     performed strictly  in accordance with the  Contract Drawings provided
     by  the Port  Authority to the  Lessee covering  such work.   The Port
     Authority, within five (5) business  days thereafter shall inspect the
     particular  work as to which  the certification has  been given and if
     the  same has  been completed  as  certified by  the  Lessee and  such
     architect  or  engineer,  the  Port  Authority's  Assistant  Director,
     Physical Facilities, World  Trade Department, shall so  certify to the
     Port Authority and the Lessee subject to the condition  that all risks
     thereafter with respect to the construction and installation  work and
     any liability therefor for  negligence or other reason shall  be borne
     by Lessee.   The  Port Authority  within thirty  (30) days after  such
     certification by such  Assistant Director,  Physical Facilities,  will
     pay the  Lessee  the applicable  price pertaining  to such  particular
     work.   In  addition thereto and  solely in  connection with  the work
     which the Lessee  is to perform pursuant to paragraphs  (c) and (d) of
     this Section 42, in the event there are unforeseen conditions actually
     encountered  by  the  Lessee  in  performance   of  such  work,  which
     conditions were unknown to the Lessee  at the time of its execution of
     this Agreement and which could not have been reasonably anticipated by
     the  Lessee, and such unforeseen  conditions increase the  cost of the
     performance of such work, then in addition to the fixed price the Port
     Authority  is to pay  for such work,  the Port Authority  will pay the
     Lessee the Lessee's reasonable additional cost directly resulting from
     such unforeseen condition.  Notwithstanding anything in this paragraph
     (f) to the  contrary, with respect  to the certification set  forth in
     this  paragraph (f),  the  Lessee may  notify  the Port  Authority  in
     writing  that the certification of the  Lessee's architect or engineer
     shall also  be deemed to be  the certification of the  Lessee with the
     same force and effect as if given directly by the Lessee.

                    (g)  For purposes of this  Agreement the work described
     in subdivisions (ii) and (v)  of paragraph (a) and paragraphs  (e) and
     (i)  of this Section are collectively called  the "Landlord Work".  It
     is hereby  understood and agreed  that except  for the work  which the
     Lessee is  to  perform pursuant  to  paragraphs (c)  and (d)  of  this
     Section, the Lessee shall not be required to perform any  ADA required
     work outside the Lessee's premises.

                    (h)  The Port Authority hereby  agrees that it will not
     impose  upon the  Lessee any  utility or  freight elevator  charges or
     inspection, filing, sign-off  or other fees  or charges in  connection

                                       59


     with  the Lessee's  performance of  the Additional  Lessee Work.   For
     purposes of  this Agreement "Additional  Lessee Work" shall  mean that
     work which  the Lessee is  to perform pursuant to  paragraphs (c), (d)
     and (e) of this Section 42.

                    (i)  Except for  vinyl asbestos  tiles and  asbestos or
     asbestos-containing materials located within or behind the mullions on
     the interior of the exterior walls of the premises, the Port Authority
     hereby represents  that to  the  best of  its knowledge  there are  no
     asbestos  and asbestos-containing materials  located in  the premises.
     "Asbestos" or "asbestos containing-materials"  as used herein shall be
     as  defined  in  the  guidelines  established  by  the  United  States
     Environmental Protection Agency  ("USEPA") as set  forth in the  USEPA
     publication  entitled  "Guidance  for Controlling  Asbestos-Containing
     Materials in Building" (EPA 560/5-85-024, June 1985).  Notwithstanding
     the foregoing, in the  event that the asbestos  or asbestos-containing
     materials  are discovered  in the  premises prior  to the  Prior Entry
     Date, then  the Port Authority will remove or cause same to be removed
     from  the premises prior to  the Prior Entry Date.   In the event that
     asbestos  or  asbestos-containing  materials  are  discovered  in  the
     premises  subsequent  to  the  Prior  Entry  Date,   the  Lessee  will
     expeditiously notify the Port Authority of their existence and if such
     asbestos or asbestos-containing materials  were not installed  therein
     by  the Lessee or its  contractor, the Port  Authority will diligently
     remove or cause same to be removed and will make reasonable efforts to
     minimize disruption to the  Lessee's operations.  The Lessee  will not
     be entitled to any rental abatement during performance of such removal
     work occurring subsequent to  the commencement date of the term of the
     letting hereunder unless  the Lessee is unable to use  such portion of
     the premises during performance of  such work in which case the  basic
     rental  and additional basic rental  for such portion  of the premises
     shall  be abated in accordance  with the provisions  of the Section of
     this Agreement  entitled "Abatement  of Rental"  during the  period of
     such non use due  to such removal work.  In the  event that the Lessee
     prior to the commencement date of the term of the letting is unable to
     perform  construction  work in  all or  a  substantial portion  of the
     premises  during performance of such asbestos removal work by the Port
     Authority,  then the two hundred  fourteen (214) day  period in clause
     (i) of paragraph (a)  of the Section of this Agreement entitled "Term"
     shall be extended by one day for each day that the Lessee is unable to
     perform its construction work in  all or a substantial portion of  the
     premises due to the asbestos removal work being performed by  the Port
     Authority.  The Port  Authority hereby agrees to refireproof  any area
     in the premises, including any structural steel members located in the
     ceiling  area of the  Lessee's premises necessitated  by such asbestos
     removal work.   The Port Authority upon  completion of the removal  of
     asbestos  or  asbestos-containing  materials  from  the  premises will
     furnish  written certification  of same  to the  Lessee from  the Port
     Authority's  Assistant  Director,  Physical  Facilities,  World  Trade
     Department.  In no event will the Port Authority be required to remove
     asbestos or any asbestos-containing materials located within or behind
     the mullions on the interior of the exterior walls of the premises.

                                       60


                    (a)  If  the Lessee  no  later than  September 1,  1997
     shall notify the Port Authority in  writing that it desires to lease a
     single block  of additional space on the 24th floor of the South Tower
     Building  contiguous to  the Lessee's initial  premises on  said floor
     (hereinafter referred  to as the  "Additional Space I"),  and provided
     that the  Lessee  is not  then  in default  under  any of  the  terms,
     provisions,  covenants and  conditions  of this  Agreement beyond  the
     applicable cure period  therefor and  this Agreement is  then in  full
     force and effect, the Port Authority within twenty (20) days following
     the  date of the Lessee's notice will  notify the Lessee in writing of
     the  location  and  configuration  of the  Additional  Space  I  (such
     configuration  to  be  commercially  reasonable)  setting  forth   the
     commencement date of  the letting  thereof (June 1,  1998, subject  to
     postponement due to  causes or  conditions beyond the  control of  the
     Port Authority),  the exact number  of rentable square  feet contained
     therein (such number of rentable square feet to be no  less than 5,000
     nor more than  7,000 rentable  square feet as  determined by the  Port
     Authority, such determination of the number of rentable square feet to
     be determined by  the Port Authority  in the same  manner as the  Port
     Authority  determined  the rentable  square  footage  for the  initial
     premises)  and the annual basic rental rate therefore.  The letting of
     the Additional Space  I shall be on an "as is" basis with no finishing
     allowance provided that the  Port Authority prior to the  commencement
     date of  the letting of same  will provide in such  Additional Space I
     the  Landlord Work,  as such term  is defined  in the  Section of this
     Agreement entitled "Port Authority Work; Additional Lessee Work".   In
     addition  rental  for the  Additional Space  I  shall commence  on the
     ninetieth (90th) day from  the commencement date of the letting of the
     Additional Space I, as such commencement  date may be postponed due to
     causes  or  conditions  beyond  the  control  of the  Port  Authority.
     Thereupon,  the Lessee  shall have the  right, by  notice to  the Port
     Authority  subscribed  by  an authorized  officer  of  the  Lessee and
     delivered to the Port Authority within ten (10) days after its receipt
     of the Port Authority's notice:  

                         (i)  to  accept  the Additional  Space I
               unconditionally for the balance of the term of the
               letting hereunder  at  the basic  rental rate  set
               forth in the Port Authority's notice; or

                         (ii) to  accept  the Additional  Space I
               unconditionally for the balance of the term of the
               letting  hereunder but advising the Port Authority
               that  the  Lessee  has concluded  that  the annual
               basic rental rate specified by the  Port Authority
               in its notice  is not the  fair market rental  for
               the Additional Space I.  

     Within  thirty (30)  days  after  the later  of  the date  the  Lessee
     notifies  the  Port  Authority  that it  unconditionally  accepts  the
     Additional Space I in  accordance with subdivision (i), above,  or, in
     the  event that the annual basic rental  for the Additional Space I is
     determined  by  arbitration  in  accordance  with  the  provisions  of
     paragraph  (e) of this Section,  the date that  the arbitrators render
     their determination  of fair  market rental,  the Port Authority  will
     prepare  and tender  to  the Lessee  for  its execution  an  agreement
     supplementing this  Agreement  and providing  for the  letting of  the
     Additional  Space I.   The  agreement tendered  by the  Port Authority

                                       61


     shall contain an exhibit  depicting the Additional Space I,  shall set
     forth the annual basic  rental payable for the Additional Space  I and
     shall  include the  effective date  of the  letting of  the Additional
     Space  I.   The  Lessee shall  execute,  acknowledge and  deliver  the
     aforesaid agreement  to the  Port Authority  within  thirty (30)  days
     after delivery of same  to it.  The Supplemental Agreement prepared by
     the  Port Authority pursuant to  the provisions of  this paragraph (a)
     shall provide for  the letting of the Additional Space  I upon all the
     terms and conditions set forth in this Agreement except as modified by
     the provisions of this paragraph (a) and paragraph (e) below.   If the
     Lessee shall  fail to execute,  acknowledge and deliver  the agreement
     tendered to it by the Port Authority within the aforesaid time period,
     then  the Lessee  shall have no  further right  to or  interest in the
     Additional  Space I  the  letting of  which  is  covered by  the  said
     agreement, and the Port  Authority shall have  the right to lease  the
     same  to a third party on terms  and conditions more or less favorable
     than the terms and conditions which would have governed the letting to
     the  Lessee, all  as  the  Port  Authority  in  its  discretion  shall
     determine.   The Lessee  shall have  a single  option only  to include
     additional space in the premises pursuant to this paragraph (a).

                    (b)  If the Lessee  not later than  June 1, 2005  shall
     notify the Port  Authority in writing that it desires  to lease all of
     the space shown  in diagonal  hatching on the  sketch annexed  hereto,
     made a part hereof  and marked "Exhibit A-3" (hereinafter  referred to
     as  the "Additional Space  II"), and provided  that the Lessee  is not
     then  in default  under any  of the  terms, provisions,  covenants and
     conditions  of  this  Agreement  beyond  the  applicable  cure  period
     therefor and this Agreement is then in full force and effect, the Port
     Authority within twenty (20)  days following the date of  the Lessee's
     notice  will  notify the  Lessee  in writing  of  the exact  number of
     rentable  square feet  contained therein  and the annual  basic rental
     rate therefore.  The letting of the Additional Space II shall commence
     on March 1, 2006, subject to  postponement due to causes or conditions
     beyond the control of the Port Authority, and such letting shall be on
     an "as  is" basis with  no finishing allowance provided  that the Port
     Authority prior to  the commencement date of the  letting of same will
     provide in such Additional Space II the Landlord Work, as such term is
     defined in  the  Section of  this Agreement  entitled "Port  Authority
     Work;  Additional Lessee Work".  In addition rental for the Additional
     Space   II  will  commence  on  the  ninetieth  (90th)  day  from  the
     commencement date of the  letting of such space, as  such commencement
     date may be postponed  due to causes or conditions  beyond the control
     of the Port Authority.  Thereupon, the Lessee shall have the right, by
     notice  to the Port Authority  subscribed by an  authorized officer of
     the Lessee and  delivered to the Port  Authority within ten (10)  days
     after its receipt of the Port Authority's notice:  

                         (i)  to accept the  Additional Space  II
               unconditionally for the balance of the term of the
               letting at the basic rental  rate set forth in the
               Port Authority's notice; or

                         (ii) to accept the  Additional Space  II
               unconditionally for the balance of the term of the
               letting hereunder but  advising the Port Authority
               that  the  Lessee has  concluded  that  the annual
               basic rental  rate specified by the Port Authority

                                       62


               in its notice  is not the  fair market rental  for
               the Additional Space II.  

     Within  thirty  (30)  days after  the  later of  the  date  the Lessee
     notifies  the  Port  Authority  that it  unconditionally  accepts  the
     Additional  Space II in accordance with subdivision (i), above, or, in
     the event that the annual basic rental for the Additional  Space II is
     determined  by  arbitration  in  accordance  with  the  provisions  of
     paragraph  (e) of this Section,  the date that  the arbitrators render
     their determination  of fair  market rental,  the Port Authority  will
     prepare  and tender  to  the Lessee  for  its execution  an  agreement
     supplementing this  Agreement  and providing  for the  letting of  the
     Additional Space II.   The  agreement tendered by  the Port  Authority
     shall contain Exhibit A-3 depicting the Additional Space II, shall set
     forth the annual basic rental payable for the Additional Space II  and
     shall  include the  effective date  of the  letting of  the Additional
     Space II.  Any  Supplemental Agreement prepared by the  Port Authority
     pursuant to the provisions of this paragraph (b) shall provide for the
     letting of the Additional Space  II upon all the terms and  conditions
     set forth in  this Agreement except  as modified by the  provisions of
     this paragraph (a) and paragraph (e) below.  The Lessee shall execute,
     acknowledge and deliver the aforesaid agreement to the Port  Authority
     within thirty (30) days after  delivery of same to it.   If the Lessee
     shall fail to execute, acknowledge  and deliver the agreement tendered
     to it by the Port Authority within the aforesaid time period, then the
     Lessee shall have no  further right to  or interest in the  Additional
     Space II  the letting of which  is covered by the  said agreement, and
     the Port Authority shall  have the right to lease the  same to a third
     party on  terms and conditions more  or less favorable than  the terms
     and  conditions which would have  governed the letting  to the Lessee,
     all as the Port Authority in its discretion shall determine,  but such
     failure to  execute and  acknowledge such  agreement  within the  time
     period provided covering the Additional Space II shall not diminish or
     affect  the  Lessee's  rights under  paragraph  (a)  above to  include
     Additional Space  I in the premises.   The Lessee shall  have a single
     option  only to include additional  space in the  premises pursuant to
     this paragraph (b).

                    (c)  If  any  time  during  the  term  of  the  letting
     hereunder the Lessee shall  notify the Port Authority in  writing that
     it desires to lease a single block of space contiguous to its premises
     on the  24th floor of the South Tower Building  or located on the 22nd
     or 25th floors of the South Tower Building and provided  that the Port
     Authority  acting in good faith determines that such space will become
     available for leasing within  two hundred seventy (270) days  from the
     date of  the Lessee's  notice (hereinafter  referred to as  Additional
     Space  III) and  provided,  further that  the  Lessee is  not then  in
     default under any of the  terms, provisions, covenants and  conditions
     of  this Agreement beyond the applicable cure period therefor and this
     Agreement is then in  full force and effect, the Port Authority within
     twenty (20) business days after receipt of such notice from the Lessee
     will notify the Lessee in  writing of the availability for letting  of
     the Additional Space  III setting  forth the date  the Port  Authority
     expects  the Additional  Space  III to  be  ready for  occupancy,  the
     location  and   configuration  thereof   (such  configuration   to  be
     commercially  reasonable), the  exact number  of rentable  square feet
     contained therein and  the annual  basic rental rate  therefore.   The
     letting  of the Additional Space III shall be on an "as is" basis with

                                       63


     no finishing allowance to  be provided by the Port  Authority provided
     that the Port Authority prior to the  commencement date of the letting
     of  such space will provide in  such Additional Space III the Landlord
     Work,  as  such  term is  defined  in the  Section  of  this Agreement
     entitled "Port  Authority Work; Additional  Lessee Work".   Payment of
     rental for the  Additional Space  III will commence  on the  ninetieth
     (90th) day from the commencement date of the letting of  same, as such
     commencement  date may be postponed due to causes or conditions beyond
     the control  of the Port Authority.   Thereupon, the Lessee shall have
     the right, by notice to the Port Authority subscribed by an authorized
     officer of the Lessee and delivered  to the Port Authority within  ten
     (10) days after its receipt of the Port Authority's notice:  

                         (i)  to accept the Additional  Space III
               unconditionally for the balance of the term of the
               letting  hereunder at  the basic  rental  rate set
               forth in the Port Authority's notice; or

                         (ii) to accept the Additional  Space III
               unconditionally for the balance of the term of the
               letting hereunder but advising the  Port Authority
               that  the  Lessee has  concluded  that  the annual
               basic rental  rate specified by the Port Authority
               is not  the fair market rental  for the Additional
               Space III.  

     Within  thirty (30)  days  after  the later  of  the date  the  Lessee
     notifies  the  Port  Authority  that it  unconditionally  accepts  the
     Additional Space III in accordance with subdivision (i), above, or, in
     the event that the annual basic rental for the Additional Space III is
     determined  by  arbitration  in  accordance  with  the  provisions  of
     subdivision (ii), above,  and of  paragraph (e) of  this Section,  the
     date that  the arbitrators render  their determination of  fair market
     rental, the Port  Authority will prepare and tender to  the Lessee for
     its execution an agreement  supplementing this Agreement and providing
     for  the letting of the Additional  Space III.  The agreement tendered
     by  the  Port   Authority  shall  contain  an  exhibit  depicting  the
     Additional  Space III, shall set forth the annual basic rental payable
     for  the Additional Space III and shall  include the effective date of
     the letting of the  Additional Space III.  Any  Supplemental Agreement
     prepared  by the  Port Authority  pursuant to  the provisions  of this
     paragraph  (c) shall provide for  the letting of  the Additional Space
     III  upon all  the terms  and conditions set  forth in  this Agreement
     except  as  modified  by the  provisions  of  this  paragraph (c)  and
     paragraph  (e)  below.   The  Lessee  shall  execute, acknowledge  and
     deliver the aforesaid  agreement to the  Port Authority within  thirty
     (30) days after delivery of same to  it.  If the Lessee shall fail  to
     execute, acknowledge and deliver  the agreement tendered to it  by the
     Port Authority within the aforesaid time period, then the Lessee shall
     have no further  right to or interest in the  Additional Space III the
     letting  of which  is  covered by  the said  agreement,  and the  Port
     Authority shall have the right to lease  the same to a third party  on
     terms  and  conditions  more or  less  favorable  than  the terms  and
     conditions which would have governed the letting to the Lessee, all as
     the  Port Authority  in its  discretion shall  determine.   The Lessee
     expressly  understands  and agrees  that  the  Port Authority  in  its
     discretion exercised in good faith shall determine when any Additional
     Space III is available for leasing, and nothing contained herein shall

                                       64


     obligate or be  construed to obligate the Port Authority  to offer any
     space to the  Lessee other than in  its existing configuration nor  to
     terminate  the  letting or  otherwise end  the  occupancy of  a tenant
     currently in  possession of any space, including  the Additional Space
     III, prior to the scheduled expiration date of such letting, nor shall
     anything  herein be  deemed  to prevent  the  Port Authority,  without
     liability of  any kind to the  Lessee, from renewing or  extending any
     lease covering  any  space on  any of  the designated  floors or  from
     otherwise continuing in occupancy a tenant of any space located on any
     of the designated floors, nor shall anything herein be deemed to limit
     the  Port Authority's right to freely discuss and negotiate with third
     parties for the leasing  of any space, including the  Additional Space
     III.  The Lessee's right to notify the Port Authority  that it desires
     to  lease Additional  Space III  shall continue throughout  the entire
     term of the letting hereinabove  described irrespective of whether the
     Lessee shall have added Additional Space III to the premises or of the
     number  of times  the Lessee  shall have  notified the  Port Authority
     during such period provided however that the Lessee shall not have the
     right to notify the Port Authority of its desire to let any Additional
     Space III within three hundred sixty-five (365) days subsequent to the
     last  prior  such  notice sent  by  the  Lessee  with respect  to  any
     Additional Space III unless (i) the Port Authority in response to such
     last prior  notice determined that  the additional space  requested by
     the Lessee  was not available for  leasing or (ii) the  Lessee and the
     Port Authority pursuant to the last such prior notice  entered into an
     agreement providing for the  inclusion of Additional Space III  in the
     premises and in  either said  case the said  three hundred  sixty-five
     (365)-day  period shall be reduced to ninety  (90) days.  In the event
     that prior to  exercising its right to include Additional  Space II in
     the  premises pursuant to  paragraph (b),  above, the  Lessee includes
     Additional Space III  in the  premises pursuant to  the provisions  of
     this  paragraph (c), and such  Additional Space III  includes all or a
     portion of Additional  Space II, then for purposes of paragraph (b) of
     this  Section 43  Additional  Space II  as  defined therein  shall  be
     reduced by all or such portion thereof which may have become a part of
     the premises as Additional Space III pursuant to the provision of this
     paragraph (c).

                    (d)  The  Lessee   at  any   time  during   the  period
     commencing  with  the Prior  Entry Date  and  continuing for  547 days
     thereafter  (hereinafter  in this  paragraph  (d)  called the  "Option
     Period") shall have the right to notify the Port Authority  in writing
     that it  desires to lease all  or any portion  (such portion to  be as
     designated  by the  Lessee but  such portion  to be contiguous  to the
     Lessee's then existing  premises, to  be no less  than 3,500  rentable
     square feet  and the balance of  the Additional Space IV  not taken by
     the Lessee  to be a  marketable configuration) of  the space  shown in
     diagonal hatching on the sketch attached hereto as Exhibit A-2 (all or
     any portion of  such space being  hereinafter called Additional  Space
     IV), provided  that the Lessee  at the time  of such notice  is not in
     default under any term, provision or covenant of this Agreement beyond
     the applicable grace  period therefor and  provided further that  this
     Agreement and the letting hereunder are then in full force and effect.
     In the event that the Lessee during the Option Period has not notified
     the Port Authority pursuant to the immediately preceding sentence that
     it desires to lease Additional Space  IV and in the further event that
     during  the Option Period  the Port  Authority receives  a non-binding
     bona fide proposal from a third party to lease all or a portion of the

                                       65


     Additional Space  IV (such portion to  be no less than  3,500 rentable
     square feet), then  prior to entering into  an agreement with a  third
     party covering the letting of all or a portion of the Additional Space
     IV, the  Port Authority  shall offer the  Additional Space  IV to  the
     Lessee by notice in writing  (it being understood that from  and after
     the  date of such notice the Lessee shall have no further right to add
     Additional Space IV to the premises  pursuant to the first sentence of
     this  paragraph  (d))  and  the Lessee  shall  have  the  right  to be
     exercised within thirty  (30) days after  the date of such  notice, to
     advise  the Port Authority whether it wishes to include the Additional
     Space IV  in the premises.   If the  Lessee shall timely  indicate its
     desire  to add  the Additional  Space IV  to the  premises under  this
     Agreement  either pursuant  to the  first or  second sentence  of this
     paragraph (d),  as the case  may be, the Port  Authority shall prepare
     and  tender to  the  Lessee for  its  execution an  agreement  further
     supplementing  this  Agreement and  providing for  the letting  of the
     Additional  Space IV hereunder.   The agreement shall  provide for the
     letting of Additional  Space IV on the terms and  conditions set forth
     in this Agreement, except as provided otherwise in this paragraph (d).
     The  Supplemental  Agreement  tendered  by the  Port  Authority  shall
     contain an exhibit depicting  the Additional Space IV and  a statement
     of  the number of rentable square feet comprising the Additional Space
     IV,  such calculation  of the  number of  rentable square  feet to  be
     determined  by  the Port  Authority  in the  same manner  as  the Port
     Authority  determined  the rentable  square  footage  for the  initial
     premises.   Such Supplemental Agreement for  the letting of Additional
     Space IV shall provide  for a commencement date occurring  two hundred
     ten (210)  days from the date  the premises are made  available to the
     Lessee  for  construction  purposes  (provided  that  if  the  period,
     hereinafter called the "Additional Space IV period", from the date the
     Additional Space IV is  made available for construction by  the Lessee
     through  the expiration date of the term of the letting, as determined
     in accordance with  the provisions  of the Section  of this  Agreement
     entitled "Term", contains less than one hundred ninety-six (196) whole
     calendar months, then the  aforesaid two hundred ten (210)  day amount
     shall be  replaced by the  product obtained  by multiplying  210 by  a
     fraction the numerator of which shall be the number of whole  calendar
     months in  the Additional Space IV period and the denominator of which
     shall be 196) or  such earlier date as  the Lessee commences  business
     operations  therein.   The rent commencement  date for  the Additional
     Space IV will be two hundred seventy (270)  days from the commencement
     date but if the period between the commencement date of the letting of
     the Additional Space IV and the expiration date of the  letting of the
     entire premises as set forth in the Section of this Agreement entitled
     "Term"  is  less  than  189  whole  calendar  months,  then  the  rent
     commencement  date  for Additional  Space  IV shall  be  the following
     number of days from the commencement date of the letting of same, such
     number of days to be obtained by multiplying two hundred seventy (270)
     by  a fraction  the numerator of  which shall  be the  number of whole
     calendar  months in  the  period from  the  commencement date  of  the
     letting of the Additional Space IV to the aforesaid expiration date of
     the  letting and  the denominator  of which  shall be  189.   The Port
     Authority will provide the Lessee a finishing allowance  equivalent to
     the product obtained by  multiplying $62.00 by the number  of rentable
     square feet  in the Additional Space  IV provided that if  the term of
     the letting  of Additional Space  IV is  less than 189  whole calendar
     months, then for purposes of  determining the finishing allowance  the
     said $62.00 shall be  replaced by the product obtained  by multiplying

                                       66


     $62.00 by a  fraction the numerator  of which shall  be the number  of
     whole calendar months in the period from  the commencement date of the
     letting  of Additional Space IV to  the expiration date of the letting
     of same and the  denominator of which shall  be 189.  The Lessee  will
     accept the Additional Space IV in  its "as is" condition, but the Port
     Authority will provide prior  to the date the  Additional Space IV  is
     made  available to  the  Lessee the  Landlord Work,  as  such term  is
     defined  in the  Section  of this  Agreement entitled  "Port Authority
     Work;  Additional Lessee Work".   The basic rental  for the Additional
     Space  shall be at the following annual per rentable square foot rates
     for the following periods:  for the period commencing with the payment
     of  basic rental  for Additional  Space IV  and continuing  up to  and
     including  the  day  preceding  the  fifth  anniversary  of  the  Rent
     Commencement Date  (as such term  is defined in  paragraph (c)  of the
     Section of  this Agreement entitled  "Basic Rental") the  Lessee shall
     pay basic rental  for the Additional  Space IV at  the annual rate  of
     $31.00  per rentable square foot;  for the period  commencing with the
     fifth  anniversary of the Rent  Commencement Date up  to and including
     the  day  preceding   the  tenth  (10th)   anniversary  of  the   Rent
     Commencement  Date,  the  Lessee  shall   pay  basic  rental  for  the
     Additional Space IV at  the annual rate of $33.75  per rentable square
     foot;  and for the period commencing with the tenth (10th) anniversary
     of the Rent  Commencement Date through the balance of  the term of the
     letting, the Lessee shall pay basic rental for the Additional Space IV
     at the annual rate of $36.50 per rentable square foot.  In addition to
     the basic  rental, the Lessee  commencing with  the rent  commencement
     date shall  pay additional basic rental for the Additional Space IV in
     accordance with the provisions of Schedule A attached hereto, the base
     dates and  amounts set forth in  said Schedule A to  remain unchanged.
     In  the event the Lessee does not  so advise the Port Authority of its
     desire to add Additional  Space IV within the time  period hereinabove
     specified  or  shall  fail to  execute,  acknowledge  and  deliver the
     agreement to the Port Authority within the time period hereinabove set
     forth, then the Lessee shall have no further right or  interest in the
     Additional  Space  IV pursuant  to this  paragraph  (d), and  the Port
     Authority shall have the right to lease the same to any third party on
     terms  and  conditions  more or  less  favorable  than  the terms  and
     conditions which would have governed the letting to the Lessee, all as
     the Port Authority  in its  discretion may determine.   If  Additional
     Space IV  shall become  a part  of the  premises under  this Agreement
     pursuant  to and in accordance  with the provisions  of this paragraph
     (d),  then  at  such  time  the Lessee  shall  have  no  right  to add
     Additional Space I to  the premises pursuant to paragraph  (a) of this
     Section 43 and  all rights and obligations  of the Port  Authority and
     the Lessee with respect to  Additional Space I shall be null  and void
     and of no further force or effect.  

                    (e)  In the event the  Lessee concludes that the annual
     basic  rental for  the  Additional  Space  I  specified  by  the  Port
     Authority pursuant to paragraph  (a), above, for the Additional  Space
     II specified by the Port Authority pursuant to paragraph (b) above, or
     the Additional Space III  pursuant to paragraph (c) above,  is greater
     than the  fair market rental for  any such space, the  Lessee shall so
     advise the Port  Authority and shall request arbitration  with respect
     thereto.  Such  arbitration shall be by  three arbitrators, one  to be
     appointed by the Port Authority, one to be appointed by the Lessee and
     the  third  to be  appointed  by the  arbitrators so  appointed.   The
     arbitration  shall be  pursuant  to the  then  rules of  the  American

                                       67


     Arbitration Association or any successor organization and the question
     to be answered by the arbitrators shall be:

                              "Is  the  annual basic  rental
                    established   by   the  Port   Authority
                    greater than the fair market  rental for
                    the Additional Space I or the Additional
                    Space II or the Additional Space III (as
                    the case may be)  for the balance of the
                    term of the letting under the Lease?" 

     If the arbitrators' decision is in the negative (or if the Lessee does
     not  contest the rental rate  after specification thereof  by the Port
     Authority) then from and after the first day for payment of rental for
     the Additional Space  I or the Additional Space  II, or the Additional
     Space  III, as  the case  may  be, the  Lessee shall  pay to  the Port
     Authority  such  annual  basic  rental  in  advance  in equal  monthly
     installments throughout the balance  of the term of the  letting under
     this Agreement.  If the decision of the arbitrators is that the annual
     basic rental specified by the Port Authority is greater than  the fair
     market rental for the  Additional Space I, the Additional  Space II or
     the Additional Space  III, as the case  may be, the  arbitrators shall
     thereupon determine the fair  market rental for the applicable  space,
     and in such event  from and after the first  day for payment of  basic
     rental for  the Additional Space  I, the  Additional Space  II or  the
     Additional Space III, as the case may be, the Lessee  shall pay to the
     Port  Authority in  advance in  equal  monthly installments  an annual
     basic rental  equal to  the fair  market rental  as determined by  the
     arbitrators.  In the event the  annual basic rental for the Additional
     Space I, the Additional Space  II or the Additional Space III,  as the
     case  may be, has not been determined  as herein provided prior to the
     commencement date  for payment thereof,  the Lessee shall  pay monthly
     installments  of annual basic rental  for the Additional  Space I, the
     Additional  Space II or the Additional Space  III, as the case may be,
     at the  annual per rentable  square foot rate  then in effect  for the
     initial  premises, and upon  determination of the  annual basic rental
     pursuant to the provisions  of this Section, the Lessee  shall, within
     thirty (30)  days thereafter, pay any amount due to the Port Authority
     arising out  of the  excess (if  any) of  the monthly installments  of
     annual  basic rental  as so determined  over the  monthly installments
     thereof  actually paid by the Lessee for such period, provided however
     that if the  sum of the  monthly installments of  annual basic  rental
     actually  paid by the Lessee for such  period are in excess of the sum
     of the monthly installments determined by arbitration to be payable by
     the Lessee for  such period,  the Port Authority  shall within  thirty
     (30) days thereafter, pay such excess to the Lessee and if such excess
     is  not so  paid within  thirty (30)  days, then  the Lessee  shall be
     entitled to  a credit for such excess to be applied against its rental
     obligations next  becoming due for any such space.  The Port Authority
     and the Lessee shall each bear the cost of the arbitrator appointed by
     them.  All other costs of  such arbitration, including but not limited
     to the cost  of the third  arbitrator, shall be  borne equally by  the
     Port Authority and the Lessee. 
      
                    (f)  In addition to the payment of basic rental for any
     Additional Space I,  Additional Space  II or Additional  Space III  as
     provided  herein, the Lessee  shall, from  and after  the commencement
     date for payment of rental therefor and continuing for  the balance of

                                       68


     the term of  the letting  under this Agreement,  pay additional  basic
     rental  for  the  Additional Space  I,  Additional  Space  II and  the
     Additional  Space III,  as  the case  may be,  in accordance  with the
     provisions of Schedule A  attached hereto, the base amounts  and dates
     set forth in said Schedule A to remain as  provided therein.  From and
     after the commencement of  the term of the  letting of the  Additional
     Space I, Additional Space  II and the Additional Space  III, paragraph
     (n)  of Section  1 of Schedule  A shall  be amended  to set  forth the
     number  of rentable square  feet constituting the  Additional Space I,
     Additional  Space II or the Additional Space  III, as the case may be,
     in addition to  the number  of rentable square  feet constituting  the
     balance of the premises, and the "Lessee's Proportionate Share" as set
     forth in  paragraph (j)  of  Section 1  of said  Schedule  A shall  be
     adjusted as provided in said paragraph.

                    (g)  For purposes  of this  Section 43, the  term "fair
     market rental" shall mean the rent that a willing tenant would pay and
     a  willing landlord  would accept  for comparable  space in  the World
     Trade  Center  (or  if there  is  no  comparable  space available  for
     comparison  at such  time then  such other  comparable space  in first
     class  office buildings  in the  vicinity of  the World  Trade Center)
     taking  into account  all  relevant factors  in connection  therewith,
     including,  but   not  limited  to,   landlord  work,  if   any,  rent
     concessions,  if any,  and finishing  allowances, if  any, then  being
     given by the Port Authority for space of comparable size, location and
     term in the  building in which the premises are  located (and if there
     is no  comparable space in the  building available at  such time, then
     the rent concessions,  if any,  landlord work, if  any, and  finishing
     allowances, if any, then being given by landlords for comparable space
     in  first class buildings  in the vicinity of  the World Trade Center)
     and the  fact that the Port Authority  will pay a brokerage commission
     in connection with  the letting  of such space,  perform the  Landlord
     Work in the  premises, will not offer  a finishing allowance  but will
     give a  ninety (90) day rent  concession.  Such determination  of fair
     market  rental  shall also  take into  account the  fact that  for any
     additional space hereunder the base dates and base years  set forth in
     Schedule A will remain unchanged as provided in paragraph (f) above.

                    (h)  Failure  of  the Lessee  to  exercise  any of  its
     options pursuant to any one of paragraphs (a), (b), (c) or (d) of this
     Section shall not affect the Lessee's right to add additional space to
     the premises pursuant to the other said paragraphs.



     Section 44.    Lessee's Right to Extend the Letting

                    (a)  The  Lessee shall  have the  right to  extend this
     Agreement and the term of the letting of the premises hereunder solely
     in its  entirety (including any  Additional Space I,  Additional Space
     II, Additional  Space III and Additional Space IV) for a five (5) year
     period effective upon the expiration  date of the term of the  letting
     hereunder, provided  that the Lessee shall  give unconditional written
     notice to the Port  Authority of its election to do  so not later than
     three  hundred sixty-five (365) days  prior to the  expiration date of
     the term of the  letting, and provided further that on the date of the
     giving of the said notice and on the effective date thereof the Lessee
     is  not in  default  in the  performance  or observance  of any  term,

                                       69


     provision or condition  of this Agreement and that the  Lessee has not
     been served with a notice of termination of this Agreement by the Port
     Authority and this Agreement is then in full force and effect.

                    (b)  In  the event  the Lessee  shall give to  the Port
     Authority  the notice  referred to  in paragraph  (a) above,  the Port
     Authority shall, not  later than  thirty (30) days  subsequent to  its
     receipt of such notice from  the Lessee, advise the Lessee in  writing
     of the Port Authority's determination of the annual basic rental to be
     payable  by the Lessee during the five (5)-year extension period which
     shall be equal to ninety-five percent (95%) of the fair market rental,
     as determined by the Port Authority, subject to the provisions of this
     paragraph (b).   In the  event the  Lessee concludes  that the  annual
     basic rental so stated in the Port Authority's notice  is greater than
     ninety-five percent (95%) of  the fair market rental for  the premises
     for the extension period,  the Lessee shall, within fifteen  (15) days
     after the date of  the Port Authority's said  notice, advise the  Port
     Authority  in writing that it has so concluded and request arbitration
     with respect thereto.  Such arbitration shall be by three arbitrators,
     one to be appointed by the Port  Authority, one to be appointed by the
     Lessee  and the third to be appointed by the arbitrators so appointed.
     The  arbitration shall be pursuant  to the then-rules  of the American
     Arbitration  Association or  by  any successor  organization, and  the
     question to be answered by the arbitrators shall be:

                         "Is the annual basic  rental established
               by the  Port  Authority greater  than  ninety-five
               percent (95%)  of the  fair market rental  for the
               premises for the extension period?"

                         If  the arbitrators' decision  is in  the negative
     (or if the Lessee does not contest the rental rate after specification
     thereof by the Port Authority)  then, from and after the first  day of
     the extended  term of the letting  hereunder, the Lessee shall  pay to
     the  Port Authority  such  annual basic  rental  for the  premises  in
     advance in equal monthly installments throughout the extension period.
     If  the decision of  the arbitrators is  that the annual  basic rental
     specified by  the Port Authority  is greater than  ninety-five percent
     (95%)  of the  fair  market  rental  for  the  extension  period,  the
     arbitrators shall  thereupon determine the fair market  rental for the
     extension period, and  in such event, from and after  the first day of
     the extended  term of the  letting the  Lessee shall pay  to the  Port
     Authority in advance  in equal  monthly installments  an annual  basic
     rental equal to the product of the fair market rental as determined by
     the arbitrators multiplied by ninety-five percent (95%).  In the event
     the annual basic  rental has  not been determined  as herein  provided
     prior  to the  commencement  of  the  extended  term  of  the  letting
     hereunder, the Lessee shall continue  to pay the monthly  installments
     of   basic  rental  at  the  rate  theretofore  in  effect,  and  upon
     determination of the annual basic rental pursuant to the provisions of
     this Section,  the Lessee shall,  within thirty (30)  days thereafter,
     pay any  amounts due to the  Port Authority arising out  of the excess
     (if any) of the monthly installments  of the annual basic rental as so
     determined  over the monthly installments thereof actually paid by the
     Lessee for  such period,  provided however,  that if  the  sum of  the
     monthly installments of the  annual basic rental actually paid  by the
     Lessee for  such  period are  in  excess of  the  sum of  the  monthly
     installments  as determined by arbitration to be payable by the Lessee

                                       70


     for  such  period,   the  Port  Authority,  within  thirty  (30)  days
     thereafter, shall pay  the amount of such excess to  the Lessee and if
     the  Port Authority fails to make  such payment within such period the
     Lessee shall be  entitled to a  credit for such  excess to be  applied
     against its rental obligations next becoming due under this Agreement.
     In addition to the  basic rental payable as provided in this paragraph
     (b), the Lessee shall, from and after the commencement of the extended
     term of the letting hereunder, continue to pay additional basic rental
     in accordance with the  provisions of Schedule A attached  hereto, the
     base  amounts  and  dates set  forth  in  said  Schedule A  to  remain
     unchanged.    The cost  of the  aforesaid  arbitration shall  be borne
     equally by the Port Authority and the Lessee.

                    (c)  For purposes  of this  Section 44, the  term "fair
     market rental" shall mean the rent that a willing tenant would pay and
     a  willing landlord  would accept  for comparable  space in  the World
     Trade  Center  (or  if there  is  no  comparable  space available  for
     comparison at such  time, then  such other comparable  space in  first
     class  office buildings  in the  vicinity of  the World  Trade Center)
     taking  into account  all  relevant factors  in connection  therewith,
     including,   but  not  limited   to,  landlord  work,   if  any,  rent
     concessions, if  any, and  finishing  allowances, if  any, then  being
     given by the Port Authority for space of comparable size, location and
     term in the building in  which the premises are located (and  if there
     is no  comparable space in  the building available at  such time, then
     the rent concessions,  if any,  landlord work, if  any, and  finishing
     allowances, if any, then being given by landlords for comparable space
     in first class buildings  in the vicinity of  the World Trade  Center)
     and the fact  that the Port Authority will pay  a brokerage commission
     in connection with such renewal  but will not perform any work  in the
     premises  nor give a finishing allowance or rent concession during the
     renewal   period,  but   such  determination   shall  not   take  into
     consideration the fact that the Port Authority will not incur a period
     during  which the  premises will  be vacant,  such factor  having been
     taken into  consideration in  specifying ninety-five percent  (95%) of
     the fair market rental as the rental; the determination of fair market
     rental shall  also take into account  the fact that the  base date and
     base years set forth in  Schedule A will remain unchanged  as provided
     in paragraph (b) above.





     Section 45.    No Gifts, Gratuities, Offers of Employment, etc.

                    (a)  During  the   term  of  the   letting  under  this
     Agreement, the Lessee shall not offer, give or agree to give  anything
     of  value either  to a  Port Authority  employee, agent,  job shopper,
     consultant, construction manager or  other person or firm representing
     the Port  Authority, or to a  member of the immediate  family (i.e., a
     spouse, child, parent, brother or sister) of any  of the foregoing, in
     connection with the performance  of duties involving transactions with
     the  Lessee on behalf of  the Port Authority  by such employee, agent,
     job shopper, consultant,  construction manager or other person or firm
     representing  the  Port Authority,  whether  or  not such  duties  are
     related  to this Agreement or any other Port Authority lease, contract


                                       71


     or matter.  Any such conduct shall be deemed a material breach of this
     Agreement.

                    (b)  As used herein, "anything  of value" shall include
     but not  be limited to any  (1) favors, such  as meals, entertainment,
     transportation (other than that contemplated  by this Agreement or any
     other Port Authority  lease or  contract), etc., which  might tend  to
     obligate  the Port  Authority employee  to the  Lessee, and  (2) gift,
     gratuity, money,  goods, equipment,  services, lodging, discounts  not
     available to  the general  public, offers  or promises of  employment,
     loans or the cancellation  thereof, preferential treatment or business
     opportunity.  Such term shall not include compensation contemplated by
     this Agreement or any other Port Authority lease or contract.

                    (c)  In addition, during the  term of the letting under
     this Agreement,  the Lessee shall not  make an offer  of employment or
     use confidential information  in a  manner proscribed by  the Code  of
     Ethics and Financial Disclosure dated  as of July 18, 1994 (a  copy of
     which is available upon request to the Office of the  Secretary of the
     Port Authority).

                    (d)  The Lessee shall  include the  provisions of  this
     Section in each sublease,  contract or subcontract entered into  under
     and pursuant to the provisions of this Agreement.

                    (e)  The  Lessee certifies  that  it has  not made  any
     offers or agreements, or given,  or agreed to give, anything  of value
     (as  defined in  paragraph (b)  of this  Section) or  taken  any other
     action  with respect to any Port Authority employee or former employee
     or immediate family member  of either which would constitute  a breach
     of ethical standards under the Code of Ethics and Financial Disclosure
     dated  as of  July 18,  1994,  referred to  in paragraph  (c) of  this
     Section, nor does the Lessee have any knowledge of any act on the part
     of  a  Port  Authority  employee  or former  Port  Authority  employee
     relating either directly or indirectly to the Lessee which constitutes
     a breach of the ethical standards set forth in said Code.

     Section 46.    Security Deposit or Letter of Credit

                    (a)  Upon the execution of this Agreement by the Lessee
     and delivery thereof to  the Port Authority, the Lessee  shall deposit
     with  the Port  Authority  (and shall  keep  deposited throughout  the
     letting  under this Agreement) the  sum of One  Hundred Fifty Thousand
     Dollars and  No Cents  ($150,000.00) either in  cash, or bonds  of the
     United States of  America, or of  the State of  New Jersey, or  of the
     State  of New  York, or  of The  Port Authority  of New  York and  New
     Jersey, having  a market value  of that  amount, as  security for  the
     full, faithful and prompt  performance of and compliance with,  on the
     part  of the  Lessee,  all of  the  terms, provisions,  covenants  and
     conditions  of this  Agreement  on its  part  to be  fulfilled,  kept,
     performed or observed.   Bonds qualifying for  deposit hereunder shall
     be in  bearer form but  if bonds  of that issue  were offered only  in
     registered form, then  the Lessee may  deposit such bond  or bonds  in
     registered form, provided,  however, that the Port Authority  shall be
     under no  obligation to  accept such deposit  of a bond  in registered
     form unless such  bond has been re-registered in the  name of the Port
     Authority  (the expense  of such  re-registration to  be borne  by the
     Lessee) in  a manner satisfactory  to the Port Authority.   The Lessee

                                       72


     may request  the Port  Authority to  accept a  registered bond  in the
     Lessee's name and if acceptable to the Port Authority the Lessee shall
     deposit  such bond together with a  bond power (and such other instru-
     ments or other documents  as the Port  Authority may require) in  form
     and substance  satisfactory to the Port  Authority.  In  the event the
     deposit is returned to  the Lessee any expenses  incurred by the  Port
     Authority in re-registering a bond to the name of the  Lessee shall be
     borne  by the  Lessee.   In  addition to  any and  all other  remedies
     available to  it, the  Port  Authority shall  have the  right, at  its
     option, at any time and from time to  time, with or without notice, to
     use the deposit or any part  thereof in whole or partial  satisfaction
     of any of its claims or demands against the Lessee.  There shall be no
     obligation  on the Port Authority  to exercise such  right and neither
     the existence  of such right  nor the  holding of  the deposit  itself
     shall cure any default or breach of  this Agreement on the part of the
     Lessee.   With respect to any bonds  deposited by the Lessee, the Port
     Authority shall have the right, in  order to satisfy any of its claims
     or demands against the Lessee, to  sell the same in whole or  in part,
     at any time  and from time  to time, with  or without prior  notice at
     public  or  private sale,  all as  determined  by the  Port Authority,
     together with the right to purchase the same at such sale  free of all
     claims, equities or  rights of redemption of  the Lessee.   The Lessee
     hereby waives all right to participate  therein and all right to prior
     notice or demand of the amount or amounts of the claims or demands  of
     the Port  Authority against the  Lessee.  The  proceeds of  every such
     sale shall  be applied by  the Port Authority  first to the  costs and
     expenses  of the  sale (including  but not  limited to  advertising or
     commission  expenses) and then to  the amounts due  the Port Authority
     from the  Lessee.   Any balance  remaining shall  be retained  in cash
     toward bringing  the deposit to the sum specified above.  In the event
     that the Port Authority shall at any time or times so use the deposit,
     or any  part thereof, or  if bonds shall  have been deposited  and the
     market  value thereof  shall have  declined below  the above-mentioned
     amount, the Lessee  shall, on demand of the Port  Authority and within
     two (2)  days thereafter, deposit  with the Port  Authority additional
     cash or bonds so as  to maintain the deposit at all times  to the full
     amount  stated  above in  this  paragraph  (a),  and  such  additional
     deposits  shall  be subject  to all  the  conditions of  this Section.
     After  the expiration or earlier termination of the letting under this
     Agreement  as  the  said letting  may  have  been  extended, and  upon
     condition that  the Lessee shall then  be in no wise  in default under
     any part of this Agreement, as this Agreement may have been amended or
     extended (or both), and  upon written request therefor by  the Lessee,
     the  Port Authority  will return  the deposit  to the Lessee  less the
     amount of any and  all unpaid claims and demands  (including estimated
     damages)  of the Port Authority by reason  of any default or breach by
     the Lessee of  this Agreement or any part thereof.   The Lessee agrees
     that  it will  not assign  or encumber  the deposit.   The  Lessee may
     collect or receive any interest or income earned on bonds and interest
     paid  on cash  deposited in  interest-bearing bank accounts,  less any
     part thereof  or amount which the  Port Authority has paid  or applied
     against the Lessee's  obligations under  this Agreement  or which  the
     Port Authority is or may hereafter be entitled or authorized by law to
     retain  or to  charge,  whether as  or  in lieu  of  an administrative
     expense, or  custodial charge,  or otherwise; provided,  however, that
     the Port Authority  shall not be obligated by this  provision to place
     or to keep cash deposited hereunder in interest-bearing bank accounts.


                                       73


                    (b)  In lieu of the security  deposit required pursuant
     to paragraph  (a) of this Section  the Lessee may deliver  to the Port
     Authority,  as security for all  obligations of the  Lessee under this
     Agreement,  a clean irrevocable letter  of credit issued  by a banking
     institution  satisfactory to  the Port  Authority and having  its main
     office within  the Port of  New York  District, in favor  of the  Port
     Authority in the  amount of One Hundred Fifty Thousand  Dollars and No
     Cents ($150,000.00).  The form and  terms of such letter of credit, as
     well as  the institution issuing it, shall be subject to the prior and
     continuing  approval of  the Port  Authority.   Such letter  of credit
     shall  provide that  it  shall continue  throughout  the term  of  the
     letting under this Agreement and for a period of not less than six (6)
     months thereafter; such continuance may be by provision for  automatic
     renewal  or by substitution of a subsequent satisfactory letter.  Upon
     notice of cancellation of  a letter of  credit the Lessee agrees  that
     unless,  by a  date twenty (20)  days prior  to the  effective date of
     cancellation,  the letter  of credit  is replaced  by security  in the
     amount  required in accordance with  paragraph (a) of  this Section or
     another  letter of credit satisfactory to the Port Authority, the Port
     Authority may draw  down the  full amount thereof  and thereafter  the
     Port Authority will hold  the same as security under  paragraph (a) of
     this Section.   Failure to provide  such letter of credit  at any time
     during the  term of the  letting which is  valid and available  to the
     Port  Authority,  including any  failure  of  any banking  institution
     issuing  any such  letter of  credit previously  accepted by  the Port
     Authority to  make one  or more  payments as may  be provided  in such
     letter of credit shall be  deemed to be a breach of this  Agreement on
     the part of the  Lessee.  Upon acceptance of such  letter of credit by
     the  Port Authority, and upon  request by the  Lessee made thereafter,
     the Port Authority will return  any security deposit theretofore  made
     under and  in accordance with the provisions  of paragraph (a) of this
     Section.   The  Lessee  shall have  the  same rights  to  receive such
     deposit during the existence of  a valid letter of credit as  it would
     have  to receive  such  deposit upon  expiration  of the  letting  and
     fulfillment of the obligations of the Lessee under this Agreement.  If
     the Port  Authority shall make  any drawing under  a letter  of credit
     held by the Port Authority hereunder, the Lessee on demand of the Port
     Authority and within two  (2) days thereafter, shall bring  the letter
     of credit back up to its full amount.

                    (c)  No action  by the  Port Authority pursuant  to the
     terms  of any letter  of credit, or  receipt by the  Port Authority of
     funds from any bank  issuing any such letter of credit, shall be or be
     deemed to be a waiver  of any default by the Lessee under the terms of
     this  Agreement  and all  remedies under  this  Agreement of  the Port
     Authority  consequent upon such default  shall not be  affected by the
     existence of or a recourse to any such letter of credit.

     Section 47.    Additional Services

                    (a)  From and  after the commencement date  of the term
     of  the letting, the Port Authority will  furnish to the Lessee in the
     premises,  for  operation  of  the equipment  comprising  special  air
     cooling facilities installed by the Lessee, condenser water sufficient
     for a rated capacity of twenty-five tons, and the Lessee agrees to pay
     to the Port Authority for such condenser water an annual charge at the
     rate  of  One  Thousand  Ninety-one  Dollars  and  Ninety-seven  Cents
     ($1,091.97)  per ton  of the  rated cooling  capacity of  the Lessee's

                                       74


     equipment as determined by the Port Authority.  If the Lessee requires
     additional  quantities of condenser water  for use in  its air cooling
     equipment, and  provided the Port Authority  has additional quantities
     available  to furnish to the  Lessee, the Port  Authority will furnish
     the  same and  the Lessee  shall pay  to the  Port Authority  for such
     additional  condenser  water  an annual  charge  at  the  rate of  One
     Thousand Ninety-one Dollars and Ninety-seven Cents ($1,091.97) per ton
     of the rated cooling capacity of the Lessee's equipment requiring such
     additional  condenser water as determined  by the Port  Authority.  In
     the event of any changes made in the Lessee's air cooling equipment or
     the  installation  thereof,  the  Lessee  shall  supply  to  the  Port
     Authority such certifications of rated capacity as  the Port Authority
     shall reasonably  request, including certifications of  third parties.
     The annual charge for condenser water, together with the annual charge
     for  additional condenser  water, shall  be payable  by the  Lessee in
     advance in equal monthly installments and shall be payable at the same
     time,  in the same manner and shall  be recoverable with like remedies
     as  if  it  were  a  part of  the  basic  rental  reserved  under this
     Agreement.

                    (b)  The   charges  for   condenser  water   stated  in
     paragraph (a), above, shall be subject  to increase from time to  time
     as follows:   "Wage  rate" as  used in this  paragraph shall  mean the
     hourly straight time  wage rate  for Engineers  as that  wage rate  is
     established  from  time to  time  by  collective bargaining  agreement
     between the  Realty Advisory  Board on Labor  Relations, Incorporated,
     acting on  behalf of  various  building owners  and  Local 94  of  the
     International Union  of Operating Engineers, AFL-CIO,  and "basic wage
     rate" shall mean the wage rate in effect on January 1, 1994.  From and
     after each wage rate established  from and after January 1, 1994,  the
     Lessee  shall  pay  annual charges  in  addition  to  the charges  for
     condenser  water and  additional condenser  water stated  in paragraph
     (a), above, such additional charges for condenser water and additional
     condenser  water to be at an annual rate  per ton equal to Two Dollars
     and Fifty Cents ($2.50)  for each one percent (1%), or  major fraction
     thereof,  that the  wage rate  so established  exceeds the  basic wage
     rate.    If  either the  Realty  Advisory  Board  on Labor  Relations,
     Incorporated,  or Local  94 of  the International  Union of  Operating
     Engineers,  AFL-CIO, shall cease  to exist or  a collective bargaining
     agreement  shall cease  to be negotiated  between the  Realty Advisory
     Board  on   Labor  Relations,  Incorporated   and  Local  94   of  the
     International  Union of  Operating Engineers,  AFL-CIO, then  the wage
     rate  to be used for computing increases  in the said charges shall be
     the  wage  rate  for   Engineers  established  under  such  collective
     bargaining agreements as the Port Authority  shall select.  If the job
     classification  "Engineers" shall  be renamed  or abolished,  then the
     Port  Authority   will  select  the   job  classification   performing
     substantially  the same labor functions as Engineers and the wage rate
     of  the  job classification  so selected  shall  be used  in computing
     increases in the charges provided for herein.

                    (c)  The furnishing of  condenser water and  additional
     condenser water by the Port Authority as provided for herein  shall be
     subject  to all of the terms, provisions and conditions of the Section
     of  this  Agreement entitled  "Services  and  Utilities".    The  Port
     Authority's  sole  obligation under  this  Section  47 is  to  provide
     condenser  water  at  a  temperature not  exceeding  eighty-five  (85)
     degrees Fahrenheit at a  rate flow of approximately three  (3) gallons

                                       75


     per  minute for each ton of the  actual rated capacity of the Lessee's
     air-cooling  equipment.   Notwithstanding that  the Port  Authority is
     obligated to  furnish  condenser water  as provided  in paragraph  (a)
     hereof, the Port Authority shall have no responsibility whatsoever for
     conditioning or cooling the air in that area of the premises served by
     the  air cooling  equipment  installed  by  the  Lessee  nor  for  the
     maintenance  therein of  any specified  temperature or  comfort level.
     The Lessee shall and does  hereby release the Port Authority from  any
     and all liability  to the Lessee  arising out of the  Port Authority's
     failure  to   provide  condenser  water  which   meets  the  aforesaid
     specifications  except  that the  Port  Authority  shall remain  fully
     liable for all damage to equipment  and other property owned or leased
     by the Lessee, or  any subtenants or desk-space users of  the premises
     (excluding, however, loss of data and any loss of business or business
     interruption losses  resulting from such equipment  or property damage
     or  data loss)  and all  personal injury  arising as  a result  of the
     condenser  water which  the Port  Authority provides  to the  point of
     connection to the  Lessee's equipment being contaminated.   The Lessee
     shall  indemnify the  Port Authority  against any  and all  claims and
     demands, losses or  damages made by  third parties for  loss of  data,
     loss of business and business  interruption losses resulting from  any
     failure   to   provide   condenser   water   meeting   the   aforesaid
     specifications.  Nothing herein shall be construed to relieve the Port
     Authority  from  supplying  heat,   ventilation  and  air  cooling  in
     accordance  with  the  provisions of  the  Section  of this  Agreement
     entitled "Services and Utilities" and the specifications set  forth in
     Schedule D.

     Section 48.    Entire Agreement

                    This  Agreement consists  of  the following:   pages  1
     through 75, inclusive, plus Exhibits A, A-1, A-2, A-3, R, TAA, X and Y
     and Schedules A, B, B-1, D, E, F and I. 

                    It constitutes  the entire agreement of  the parties on
     the subject matter hereof and may not be changed, modified, discharged
     or extended except  by written  instrument duly executed  by the  Port
     Authority and the Lessee.   The Lessee agrees that  no representations
     or  warranties  shall  be  binding  upon  the  Port  Authority  unless
     expressed in writing in this Agreement.

     these presents as of the day and year first above written.

                                   SCHEDULE A


                 1. For the purposes of  this Schedule, the following terms
     shall have the respective meanings provided below:

                    (a)    The "annual  per  rentable square  foot  factor"
     referred to in this Schedule was initially fixed at $1.25  in the City
     Agreement (as hereinafter defined) and provision was made in paragraph
     7(3) of  the City Agreement for  changes therein from time  to time to
     reflect changes in the tax rate and changes in assessed valuations.

                    (b)    "Amortized  Expenses"  shall  mean   the  annual
     amortization of expenditures incurred by the Port Authority during the
     term of  the letting under  the Lease  (as hereinafter  defined) on  a
     straight-line  basis  over  a  depreciable  life  in  accordance  with
     generally  accepted accounting principles, consistently applied by the
     Port  Authority, (with  interest  calculated at  an  annual rate  (the
     "Applicable Rate") equal to  two (2) percentage points above  the last
     twelve  (12) month average of  the twenty-five (25)  bond Revenue Bond
     Index as  published each Friday  in the "Bond  Buyer" at the  time the
     Port  Authority makes such  expenditure) for any  equipment, device or
     capital  improvement   (i)  which may  be  required by  the  insurance
     carriers providing insurance coverage  on the Facility (as hereinafter
     defined) or on any part  thereof,  (ii) the  use or presence of  which

           


     equipment,  device or capital improvement  at the Facility will reduce
     the  premiums  charged  by   the  insurance  carriers  providing  such
     insurance coverage,  (iii) which is required by law  which first takes
     effect after  the execution  of the Lease  by the  parties thereto  or
     (iv)  which is reasonably designed  as a cost-saving  measure (and the
     annual   amortization  in   respect  of   which  bears   a  reasonable
     relationship  to the  amount of  actual savings)  in the  operation or
     maintenance of the Facility.  Notwithstanding the foregoing, Amortized
     Expenses  shall  exclude expenditures  for  any  equipment, device  or
     capital improvement  made  as  part of  the  planned  capital  upgrade
     program for the electrical, HVAC and elevator systems in the Facility.


                    (c)    "Base  Operating Year"  shall mean  the calendar
     year 1995.

                    (d)    "City   Agreement"   shall  mean   that  certain
     agreement between  the Port Authority and  the City of New  York dated
     1967, as it may have been or may hereafter be supplemented or amended.

                    (e)    "Escalation Year" shall mean each  calendar year
     subsequent to the  Base Operating Year which shall include any part of
     the term of the letting under the Lease.

                    (f)    "Estimate Statement" shall mean, with respect to
     any  Escalation Year, a written statement  setting forth in reasonable
     detail  the  Port  Authority's  estimates of  Operating  Expenses  (as
     hereinafter defined) and  additional basic rental under Paragraph 3 of
     this Schedule for such Escalation Year.


                              Page 1 of Schedule A

                    (g)    "Facility"  for  the purposes  of  this Schedule
     only, shall have the meaning set  forth in paragraph (b) of Section 36
     of  the Lease,  except  that there  shall  be excluded  therefrom  the
     following buildings commonly  known as Three World Trade Center (Vista
     Hotel International), Six World Trade  Center (U.S. Customs House) and
     Seven World Trade Center.

                    (h)    "Lease"  shall mean  the agreement  of lease  to
     which this Schedule is attached.

                    (i)    "Lessee's Proportionate Share"  shall mean  that
     fraction, the numerator of which is the number of Rentable Square Feet
     in the Premises and the denominator of which is the number of rentable
     square  feet in the Facility, exclusive  of the subgrade space and all
     retail space, which fraction  may be expressed  as a percentage.   The
     Lessee and the Port Authority agree that the number of rentable square
     feet  in the Facility, exclusive of the  subgrade space and all retail
     space, is 10,173,368  rentable square  feet.  Accordingly,  as of  the
     date hereof, the Lessee's Proportionate Share is Five Hundred Seventy-
     seven Thousandths of One percent (.577%), which Share consists of Four
     Hundred Forty-two Thousandths  of One percent (.442%) for  the portion
     of  the premises  shown on  Exhibit "A",  and One  Hundred Thirty-five
     Thousandths of One  percent (.135%)  for the portion  of the  premises
     shown in diagonal hatching  on Exhibit "A-1".  The Port  Authority and

           


     the Lessee hereby  expressly acknowledge and  agree that the  Lessee's
     Proportionate Share as set forth above is  the percentage as agreed by
     the Port  Authority and the Lessee and shall not be subject to change,
     redetermination  or remeasurement  whatsoever for  any reason,  except
     that such  percentage shall  be  subject to  change  by reason  of  an
     alteration  or  improvement  made  to the  Facility  which  physically
     increases or decreases the total number of rentable square feet in the
     Facility,  exclusive of the  subgrade space and all  retail space.  If
     the number of Rentable Square Feet in the Premises shall  be increased
     or  decreased, the Lessee's Proportionate  Share shall be increased or
     decreased to take into account such  change in the number of  Rentable
     Square Feet in  the Premises, measured on a consistent  basis with the
     manner in which  the number of  Rentable Square  Feet in the  Premises
     have  been measured  as of  the date  hereof.  In  no event  shall the
     Lessee's  Proportionate Share be increased by reason of the leasing by
     the Lessee of any subgrade space in the Facility.

                    (j)    "Operating Expenses"  shall  mean the  total  of
     Amortized  Expenses  and all  other  costs  and  expenses  (and  taxes
     thereon,  if  any), without  duplication, paid  or  incurred by  or on
     behalf  of  the  Port  Authority   with  respect  to  the   operation,
     maintenance,  repair,  marketing, promoting,  servicing,  cleaning and
     policing  of the  entire Facility,  including but  not limited  to all
     buildings  and structures, equipment,  systems, elevators, escalators,
     bridges,  truck docks,  generators, fuel  tanks, common  areas, public
     areas, passageways, lobbies and mezzanines, sidewalks, curbs,  plazas,
     concourses  and other areas adjacent to the Facility, and with respect
     to  the  utilities  and  services  provided  Tenants  (as  hereinafter
     defined),  sewer  and  water  rents,  rates  and  charges  and  annual
     management  fees equal to  three percent  (3%) of  the total  of basic

                 including  Tenants,  to   the  extent  such   amounts  are

                 facility or any

                              Page 3 of Schedule A

     cost of any work or services performed in any public or common area of

                       (12)   payments  for rented  equipment  the cost  of
                 which  would  constitute  a  capital  expenditure  if  the

                 be included in Amortized Expenses;

                       (13)   any  cost or  expense of  furnishing heating,
                 ventilating, air  cooling, cleaning or  other services  to
                 retail space located in the Facility; and

                       (14)   the  portion  of  the  cost of  any  work  or

                 performed for  any Port Authority facility  other than the
                 Facility.

     If, during  all or part of  the Base Operating Year  or any Escalation
     Year, the Port  Authority shall  not furnish any  particular items  of
     work  or services  (the cost  of which  would otherwise  constitute an

           


     Operating  Expense hereunder) to portions  of the Facility  due to the
     fact that:   (X) such portions are  not occupied or leased,   (Y) such
     item of work  or service is not required  or desired by the  Tenant of
     such  portion or   (Z) such Tenant  is itself obtaining  and providing
     such item of work or service without cost to the Port Authority, then,
     for the purposes of computing Operating Expenses, the additional costs
     and expenses for such items of work or services which would reasonably
     have been incurred during such Base Operating Year or Escalation Year,
     as the  case may be, by the Port Authority, calculated on a reasonable
     basis by the Port  Authority, shall be included as  Operating Expenses
     as if the  Port Authority had at its own  expense furnished such items
     of work or services to such portion of the Facility or to such Tenant.
     In  the event the Port Authority "grosses  up" any item as provided in
     the  preceding sentence,  the Estimated  Statement and  Port Authority
     Statement  (as  hereinafter defined)  shall  include  the "grossed-up"
     figures.

                    (k)    "Payments  in lieu  of  taxes"  shall mean  such
     payments  as the Port Authority has agreed to pay The City of New York
     under the City Agreement.

                    (l)    "Port   Authority   Statement"  shall   mean  an

     Authority  shall  make  the  computations of  Operating  Expenses  and
     additional basic rental set forth in such Port Authority Statement.

                    (m)    "Rentable Square Feet in the Premises"  shall be
     d e e m e d      t o      m e a n                                     
     58,783 square feet, and shall be deemed to consist of 44,973 square
     feet as shown on Exhibit A and 13,810 square feet as shown on Exhibit
     A-1.

                              Page 4 of Schedule A

                    (n)    "Tax Base"  shall mean  the annual  per rentable
     square foot factor finally  established to be the annual  per rentable
     square foot factor  to be used in computing payments  in lieu of taxes
     for  the tax year  beginning  July  1, 1994, provided  that "tax base"
     shall  initially mean $3.76, as  same may be  adjusted pursuant to the
     City Agreement.

                    (o)    "Tax  Year" shall  mean the  twelve-month period
     established by The  City of New York as a tax year for real estate tax
     purposes.

                    (p)    "Tax Statement" shall mean a statement furnished
     by the  Port Authority to the  Lessee and prepared in  accordance with
     the applicable provisions of this Schedule  A containing a computation
     of  additional  basic  rental due  pursuant  to  Paragraph  2 of  this
     Schedule for the applicable tax year.

                    (q)    "Taxes"  shall   mean  real  estate   taxes  and
     assessments  which  may be  imposed from  time to  time by  the United

           


     States of America, the State of New York or any  municipality or other
     governmental authority  upon the  Port Authority  with respect  to the
     buildings, structures, facilities or land at the World Trade Center or
     with  respect to  the rentals  or income  therefrom in  lieu of  or in
     addition to  any tax  or assessment  which would otherwise  be a  real
     estate  tax or assessment, and  "Taxes" shall include  any payments in
     lieu of  real estate  taxes or  assessments which  may be  agreed upon
     between  the Port  Authority  and any  of  the foregoing  governmental
     authorities, other  than  payments  in  lieu  of  taxes  described  in
     subparagraph  (k)  of this  paragraph.    The  Port  Authority  hereby
     represents that as  of the date of the Lease there  are no real estate
     taxes imposed on the World Trade Center.

                    (r)    "Tenants"  shall  mean all  lessees, permittees,
     licensees and all other Port Authority-approved users and occupiers of
     space in the Facility.

                 2. From and  after each July 1  following the commencement
     date  of  the  letting  under  the  Lease,  the Lessee  shall  pay  an
     additional basic rental under the Lease at the annual rate computed by
     multiplying the rentable  square feet  in the premises  by the  excess
     over the Tax Base of the total of:  (a) the annual per rentable square
     foot amount of Taxes  for the Tax Year  beginning on that July  1; and
     (b) the  annual per  rentable  square foot  factor  used in  computing
     payments in  lieu of taxes for the Tax  Year beginning on that July 1.
     If Taxes  become payable on  a basis other  than an annual  amount per
     rentable  square foot,  the  Port Authority  shall equitably  allocate
     those Taxes  to the rentable square  feet of space in  the World Trade
     Center and will notify the Lessee of the amount of such allocation.

                 3. (a)    In  addition  to  the  additional  basic  rental
     payable by  the Lessee under  Paragraph 2 of  this Schedule, for  each
     Escalation 

                              Page 5 of Schedule A
     Year following the commencement  date of the letting under  the Lease,
     the Lessee shall  pay to  the Port Authority  additional basic  rental
     which  shall be  equal  to the  Lessee's  Proportionate Share  of  the
     amount, if any, by  which Operating Expenses for that  Escalation Year
     exceed the Operating Expenses for the Base Operating Year.

                    (b)    The Port Authority shall furnish to the Lessee: 
     (1) a  statement  certified  by  the  Manager,  Finance  and  Business
     Planning,  World  Trade  Department,   setting  forth  in  detail  all
     Operating Expenses for the Base Operating Year (separately stating any
     "grossed-up"  figures  included  therein)   not  later  than  June  30
     following the end of the Base Operating Year, (2) with respect to each
     Escalation  Year  following  the  Base  Operating  Year,  an  Estimate
     Statement for  such Escalation Year and  (3) within 180 days after the
     end  of  each Escalation  Year, a  Port  Authority Statement  for such
     Escalation Year.

                    (c)    The  Port Authority's  failure to  render a  Tax
     Statement with respect to any  Tax Year or an Estimate Statement  or a
     Port Authority Statement with respect to any Escalation Year shall not
     prejudice  the  Port Authority's  right  thereafter  to render  a  Tax
     Statement, an Estimate Statement or a Port Authority Statement, as the

           


     case may  be, with respect thereto  or with respect to  any subsequent
     Tax  Year  or  Escalation Year,  nor  shall  the  rendering  of a  Tax
     Statement  for any  Tax  Year or  a Port  Authority Statement  for any
     Escalation  Year prejudice  the Port  Authority's right  thereafter to
     render  a corrected Tax Statement or Port Authority Statement for that
     Escalation Year.  Notwithstanding the foregoing, except as provided in
     the immediately succeeding sentence, the Port Authority shall not have
     the  right to deliver a Tax Statement with  respect to any Tax Year or
     an  Estimate Statement or a  Port Authority Statement  with respect to
     any  Escalation Year,  or  to make  any  corrections to  a  previously
     delivered  Tax   Statement,  Estimate  Statement  or   Port  Authority
     Statement,  which,  in  any  event,  shall  increase   the  amount  of
     additional basic rental  which is  payable by the  Lessee pursuant  to
     Paragraph 2  or 3  hereof, after  the date which  is the  second (2nd)
     anniversary of the expiration  of the Tax  Year or Escalation Year  in
     question.   In the  event that  any Tax Statement  shall be  incorrect
     based upon an error  or omission made by  the taxing authority,  which
     error  or omission is  subsequently corrected or  discovered (e.g., an
     underbilling by the taxing  authority which is subsequently corrected)
     or based  on a  change in  the facts  used to  calculate Taxes  or the
     annual  per rentable  square  foot factor  (such  as a  change  in the
     assessment of the Facility or of the other buildings used to determine
     the  annual per rentable square  foot factor), the  Port Authority may
     deliver  a revised or corrected Tax Statement beyond the expiration of
     such  two (2)  year period.   Except as  set forth  in the immediately
     preceding sentence,  if  the  Port  Authority shall  deliver  any  Tax
     Statement,  Estimate  Statement or  Port  Authority  Statement or  any
     correction to a  Tax Statement, Estimate  Statement or Port  Authority
     Statement after the expiration of such two (2) year period, the Lessee
     shall  have  no obligation  to pay  any  increased amount  which would
     otherwise  be due  in  accordance with  such  Statement and  the  Port
     Authority  shall have  no obligation  to refund  any amount  which the
     Lessee 

                              Page 6 of Schedule A
     may  have  paid in  excess of  that which  would  otherwise be  due in
     accordance  with  such  Statement.   Nothing  herein  contained  shall
     restrict the Port Authority from  issuing a revised Estimate Statement
     from  time to time and at  any time there is  an increase in Operating
     Expenses  during  any  Escalation  Year (each  such  revised  Estimate
     Statement to identify the same categories of Operating Expenses as the
     initial Estimate Statement for that Escalation Year).

                 4. If  the  imposition  or  allocation  of  Taxes  or  the
     establishment of an annual per rentable  square foot factor to be used
     in  computing  payments in  lieu  of taxes  for  any Tax  Year  or the
     delivery to the  Lessee of  an Estimate Statement  for any  Escalation
     Year  is  delayed  for  any   reason  whatsoever,  the  Lessee   shall
     nevertheless continue to pay the additional basic rental at the annual
     rate then in effect subject to retroactive adjustments at such time as
     the Taxes are imposed or allocated,  the said per rentable square foot
     factor shall have  been established or  such Estimate Statement  shall
     have  been delivered,  provided, that  in the  event that  no Estimate
     Statement for an Escalation Year is delivered prior to the delivery of
     the Port Authority Statement for the prior Escalation Year, the Lessee
     shall pay additional basic  rental under Paragraph 3 of  this Schedule
     at  the annual rate determined  in accordance with  the Port Authority

           


     Statement  for  such  prior  Escalation Year  subject  to  retroactive
     adjustment at the time the earliest of  the Estimate Statement or Port
     Authority  Statement  for  such  Escalation Year  shall  be  delivered
     subject to  the provisions of Paragraph  3 above.   If the sum  of the
     payments made by the Lessee  pursuant to an Estimate Statement  or the
     Port  Authority Statement  for the  prior Escalation  Year shall  have
     exceeded the amount which is ultimately determined to be payable based
     upon the Port Authority Statement for the Escalation Year in question,
     the Port  Authority shall refund such excess  amount to the Lessee and
     if such excess amount to be refunded is greater than ten percent (10%)
     of the amount which is ultimately determined to be payable pursuant to
     this Schedule  A for the  Escalation Year  in question, then  the Port
     Authority  within  twenty  (20)  days  after  such  excess  amount  is
     determined  shall refund  such  excess amount  together with  interest
     thereon  at the Applicable Rate, calculated from the date each payment
     was made by the Lessee until the date such amount is actually  paid by
     the  Port Authority  or credited,  as the  case may  be.  If  the Port
     Authority shall fail to make such  payment to the Lessee within twenty
     (20) days  after  such amount  shall have  been determined  to be  due
     hereunder,  the Lessee shall be  entitled to receive  a credit against
     its ensuing installments of basic  rental and additional basic  rental
     equal to such unpaid amount.

                 5. After imposition  and allocation  of Taxes for  any Tax
     Year  and the  establishment  for each  Tax  Year  of the  annual  per
     rentable  square foot  factor used  in computing  payments in  lieu of
     taxes and  at the time of  the delivery to the Lessee  of the Estimate
     Statement or Port  Authority Statement,  as the case  may be, for  any
     Escalation Year, the Port Authority will  set forth the annual rate or
     rates of additional basic rental payable by the Lessee under Paragraph
     2 or 3, above, and  will notify the Lessee  of the amounts thereof  in
     the Estimate Statement 

                              Page 7 of Schedule A
     or Port Authority  Statement, as the  case may  be.  Additional  basic
     rental accruing under  Paragraphs 2  and 3, above,  shall be  computed
     separately and shall be payable by the Lessee to the Port Authority in
     advance in monthly installments, each  installment being equal to 1/12
     of  the  annual rate  set forth  in  the Estimate  Statement,  or Port
     Authority Statement,  as the case may  be, except that if  at the time
     the  Port Authority gives notice  to the Lessee  under this Paragraph,
     additional basic  rental shall have accrued for  a period prior to the
     notice,  the Lessee shall pay such additional basic rental in full for
     such period,  within ten  days after such  notice.  If  the additional
     basic  rental   ultimately  determined  to  be   payable  pursuant  to
     Paragraphs  2  and 3  of  this  Schedule and  set  forth  in the  Port
     Authority  Statement   for  any  Escalation  Year   shall  exceed  the
     additional basic rental actually paid pursuant to this Paragraph 5 for
     that Escalation Year, then the Lessee shall pay such excess within ten
     days  after  delivery of  such Port  Authority  Statement, and  if the
     amounts  of such additional basic  rental actually paid  by the Lessee
     during such Escalation  Year exceed  the annual amounts  set forth  in
     such  Port Authority Statement as payable pursuant to Paragraphs 2 and
     3 of this Schedule, the Port Authority will pay the Lessee such excess
     amount within twenty (20)  days after delivery of such  Port Authority
     Statement and if  such amount is not paid within  such twenty (20) day
     period the Lessee shall be entitled to a credit in such amount against

           


     its  rental  obligations next  falling due  under  the Lease  and this
     Schedule A.

                 6. If  after an  amount of  additional basic  rental shall
     have been fixed under Paragraphs 2  or 3, above, for any period, Taxes
     are imposed or the amount  of Taxes or the annual per  rentable square
     foot factor in regard to payments in lieu of taxes  used for computing
     such  additional basic rental or  the Operating Expenses  set forth in
     the  Port  Authority Statement  for that  period  shall be  changed or
     adjusted, then  the additional  basic rental  payable for that  period
     shall be recomputed and from and after notification of the imposition,
     change  or adjustment, the Lessee  shall make payments  based upon the
     recomputed additional basic  rental and upon  demand the Lessee  shall
     pay any excess in  additional basic rental as recomputed  over amounts
     of  additional basic rental theretofore actually paid.  If such change
     or adjustment results in a reduction in the amount of additional basic
     rental for any period  prior to notification, the Port  Authority will
     within twenty (20)  days of  determination of such  reduction pay  the
     Lessee   the  excess  of  the   amounts  of  additional  basic  rental
     theretofore  actually  paid  over   the  additional  basic  rental  as
     recomputed  for that  period and  if such  amount is  not paid  to the
     Lessee within such period the Lessee shall be entitled to  a credit in
     such  amount to be applied against its rental obligations next falling
     due under the Lease and this Schedule A.

                 7. If any Escalation Year begins prior to the commencement
     of, or ends after the  expiration or earlier termination of,  the term
     of  the letting  under the  Lease, the  additional basic  rental under
     Paragraph  3 of  this Schedule  with respect  to such  Escalation Year
     shall  be  apportioned  by  multiplying the  additional  basic  rental
     determined under said Paragraph 3 for the entire Escalation Year  by a
     fraction the 

                              Page 8 of Schedule A
     numerator of which  shall be the  number of  days in the  term of  the
     letting  which fall within such Escalation Year and the denominator of
     which shall be  the total number of days in such  Escalation Year.  In
     the  event of a termination  of the Lease and  the term of the letting
     thereunder,  if  the additional  basic rental  set  forth in  the Port
     Authority Statement for the Escalation Year in which such  termination
     shall  be effective,  as so  apportioned, shall exceed  the additional
     basic  rental theretofore  actually  paid by  the  Lessee pursuant  to
     Paragraph 3 of this Schedule for that Escalation Year, then the Lessee
     shall  pay such  excess within  ten days  after delivery of  such Port
     Authority Statement and if the amounts of such additional basic rental
     actually paid by  the Lessee  during such Escalation  Year exceed  the
     annual  amount set  forth  in such  Port  Authority Statement,  as  so
     apportioned,  the Port Authority shall  pay such excess  to the Lessee
     with ten days  after the  delivery of such  Port Authority  Statement,
     provided that such excess shall be reduced by any other amount owed to
     the Port Authority by  the Lessee.  Notwithstanding the  foregoing, in
     the event that letting under  the Lease shall have been terminated  as
     provided in the  Section of  the Lease entitled  "Termination" or  the
     interest of the  Lessee cancelled  pursuant thereto, or  in the  event
     that the Port Authority has re-entered, regained or resumed possession
     of the  premises in accordance with  the provisions of the  Section of
     the  Lease entitled "Right of Re-entry", the rights and obligations of

           


     the  Port  Authority  and the  Lessee  under  the  provisions of  this
     Schedule with  respect to  additional basic  rental shall  survive the
     termination of the Lease  in accordance with the terms  and provisions
     of the Section  of the Lease entitled "Survival  of the Obligations of
     the Lessee" except that  for the purpose of calculating  damages under
     such Section the  additional basic  rental under Paragraph  3 of  this
     Schedule for  the balance of the  term of the letting  under the Lease
     shall  be deemed  to  be payable  at  the annual  rate  at which  such
     additional  basic rental was payable during the Escalation Year during
     which   such   termination,  cancellation,   re-entry,   regaining  or
     resumption of possession occurred.

                 8.   Any Port Authority Statement sent to the Lessee shall
     be  conclusively binding  upon the  Lessee unless,  within twenty-four
     (24) months  after such  Statement is sent,  the Lessee  shall send  a
     written notice  to the Port Authority objecting to such Statement.  If
     the Lessee within said  twenty-four (24) month period does  not object
     to  such Statement but requests additional information with respect to
     such Statement,  the Port  Authority will  make reasonable efforts  to
     furnish  such information and the Lessee will pay the reasonable costs
     of  the Port Authority in  furnishing such information  to the Lessee.
     If such notice  objecting to an  item or items  in the Port  Authority
     Statement  is sent  within  such twenty-four  (24)  month period,  the
     Lessee  (together   with  its  accountants),  may   examine  the  Port
     Authority's  books  and records  relating to  the costs  of operating,
     maintaining,  repairing,  servicing,  cleaning  and  policing  of  the
     Facility  to determine the  accuracy of the  Port Authority Statement.
     The Lessee  recognizes  the  confidential nature  of  such  books  and
     records  and  agrees  to  use  good  faith  efforts  to  maintain  the
     information obtained from such examination  in strict confidence.   If
     after such examination, the Lessee still 

                              Page 9 of Schedule A
     disputes such Port  Authority Statement,  either party  may refer  the
     decision of the issues raised to a  reputable firm of certified public
     accountants  which shall have no business relationship with either the
     Port  Authority  or the  Lessee, selected  by  the Port  Authority and
     acceptable to the Lessee, and the decision of the accountants shall be
     conclusively binding upon the parties.  The fees and expenses involved
     in such decision shall be borne by the unsuccessful party (and if both
     parties are  partially successful,  such fees  and  expenses shall  be
     apportioned  between the  Port  Authority and  the  Lessee in  inverse
     proportion to the amount  by which such decision is  favorable to each
     party).
