this  lease,  including  payment  of rent as a monthly  rate equal to double the
amount due during the first month of the last year of  occupancy  before the end
of the expired term,  plus any  escalations  or additional  rent provided for in
this lease.

         17.  Landlord  covenants and agrees with Tenant that upon Tenant paying

covenants and conditions on Tenant's part to be observed and  performed,  Tenant
may  peaceably and quietly  enjoy the Demised  Premises  during the term of this
lease  without  hindrance  or  molestation  by  anyone  claiming  by or  through
Landlord, subject,  nevertheless, to the terms, covenants and conditions of this
lease including, but not limited to Article 22.

                                      SIGNS

the Rules and  Regulations  set forth on Schedule D annexed hereto and made part
hereof,  and with such further  reasonable  Rules and Regulations as Landlord at
any time may make and  communicate  in writing to Tenant  which,  in  Landlord's
judgement shall be necessary for the reputation,  safety,  care of appearance of
the Building  and the land  allocated  to it or the  preservation  of good order
therein,  or the operation or  maintenance  of the Building,  and such land, its
equipment,  or the more useful occupancy of the comfort of the tenants or others

said Rules and  Regulations,  or the breach of any  covenant or condition in any
lease by any other tenant in the  Building.  Landlord  agrees to apply the Rules
and Regulations in a nondiscriminating manner.

                            RIGHT TO SUBLET OR ASSIGN

         20. (A) The Tenant  covenants  that it shall not assign  this lease nor
sublet the  Demised  Premises  or any part  thereof  without  the prior  written
consent of  Landlord  in each  instance,  except on the  conditions  hereinafter
stated.  The Tenant may assign  this Lease or sublet the Demised  Premises  with
Landlord's  written  consent,  which  consent  Landlord  covenants  will  not be
unreasonably withheld, or delay consent beyond fifteen (15) days, providing:

             (i) That  such  assignment  or  sublease  is for a use  which is in
compliance  with the then existing  zoning  regulations  and the  Certificate of
Occupancy;

                                      -10-




             (ii) That at the time of such assignment or subletting, there is no
default under the material terms of this lease on the Tenant's part;

             (iii) That in the event of an  assignment,  the assignee  assume in
writing the performance of all of the terms and obligations of the within lease;

             (iv) That a duplicate  original of said  assignment  or sublease be
delivered by  registered  mail to the  Landlord at the address  herein set forth
within ten (10) days from the said assignment or sublease and within ninety (90)
days of the date that Tenant first  advises  Landlord of the name and address of
the proposed  subtenant or assignee as required,  pursuant to  subparagraph  (B)
hereof;

             (v) Such assignment or subletting shall not,  however,  release the
within Tenant from its liability for the full and faithful performance of all of
the terms and conditions of this lease;

             (vi) If this lease be assigned,  or if the Demised  Premises or any
part thereof be under let or occupied by anybody other than Tenant, Landlord may
after default by Tenant collect rent from the assignee, undertenant or occupant,
and apply the net amount collected to the rent herein reserved;

             (B)  Notwithstanding  anything  contained in this Article 20 to the
contrary,  no  assignment or  underletting  shall be made by Tenant in any event
until  Tenant  has  offered  to  terminate  this lease as of the last day of any
calendar  month during the term hereof and to vacate and  surrender  the Demised
Premises  to  Landlord  on the date  fixed in the notice  served by Tenant  upon
Landlord  (which date shall be prior to the date of such proposed  assignment or
the commencement date of such proposed lease). Simultaneously with said offer to
terminate this lease, Tenant shall advise the Landlord,  in writing, of the name
and  address of the  proposed  assignee  or  subtenant,  a  reasonably  detailed
statement of the proposed  subtenant/assignee's  business,  reasonably  detailed
financial  references,  and all the  terms,  covenants,  and  conditions  of the
proposed sublease or assignment. Landlord shall, within fifteen (15) days either
accept or reject  Tenant's offer to terminate this lease.  In the event Landlord
rejects  the offer to  terminate,  the  provisions  of  Subsection  (A) shall be
applicable.

             (C) Tenant may, without the consent of Landlord,  assign this lease
to an affiliated (i.e. a corporation 20% or more of whose capital stock is owned
by the same stockholders  owning 20% of Tenant's capital stock or more),  parent
or subsidiary  corporation  of Tenant or to a  corporation  to which it sells or
assigns  all  or  substantially  all of  its  assets  or  with  which  it may be
consolidated  or  merged,   provided  such  purchasing,   consolidated,   merged
affiliated  or  subsidiary  corporation  shall,  in writing  assume and agree to
perform all of the  obligations  of Tenant under this lease and it shall deliver
such  assumption with a copy of such assignment to Landlord within ten (10) days
thereafter, and provided further that Tenant shall not be released or discharged
from any liability under his lease by reason of such assignment.

                  (D)  Whenever  Tenant  shall claim  under this  Article or any
other part of this lease that Landlord has unreasonably  withheld or delayed its
consent to some request of Tenant,  provided  the  Landlord  does not act in bad
faith,  Tenant  shall  have no claim  for  damages  by  reason  of such  alleged
withholding  or delay,

                                      -11-




and Tenant's sole remedy thereof shall be a right to obtain specific performance
or injunction but in no event with recovery of damages.

                          LANDLORD'S ACCESS TO PREMISES

         21. (A)  Landlord or  Landlord's  agents  shall have the right to enter
and/or pass through the Demised  Premises at all reasonable  times on reasonable
notice, except in an emergency,  to examine the same, and to show them to ground
lessors, prospective purchasers or lessees or mortgagees of the Building, and to
make such repairs,  improvements  or additions as Landlord may deem necessary or
desirable  and  Landlord  shall be  allowed to take all  material  into and upon
and/or through said Demised Premises that may be required  therefor.  During the
year prior to the  expiration  of the Term of this lease,  or any renewal  term,
Landlord may exhibit the Demised  Premises to prospective  tenants or purchasers
at all  reasonable  hours and without  unreasonably  interfering  with  Tenant's
business.  If Tenant shall not be personally present to open and permit an entry
into said premises at any time,  in an  emergency,  when for any reason an entry
therein shall be necessary or  permissible,  Landlord or  Landlord's  agents may
enter the same by a master key or forcibly,  without rendering  Landlord or such
agent liable therefor (if during such entry Landlord or Landlord's  agents shall
accord reasonable care to Tenant's property).

             (B) Landlord  shall also have the right at any time,  to change the
arrangement and/or location of entrances or passageways, doors and doorways, and
corridors,  elevators,  stairs,  toilets, or other public parts of the Building,
provided,  however, that Landlord shall make no change in the arrangement and/or
location of entrances or passageways or other public parts of the Building which
will adversely  affect in any material  manner Tenant's use and enjoyment of the
Demised  Premises.  Landlord shall also have the right, at any time, to name the
Building,  including,  but not limited to, appropriate signs and/or lettering on
any or all  entrances  to the  Building,  and to  change  the  name,  number  or
designation by which the Building is commonly known.

             (C) Neither  this lease nor any use by Tenant shall give Tenant any
right or easement to the use of any door or passage or concourse connecting with
any other building or to any public conveniences,  and the use of such doors and
passages  and  concourse  and  of  such  conveniences  may be  regulated  and/or
discontinued  at any time and from time to time by  Landlord  without  notice to
Tenant, provided the same does not interfere with Tenant's access to Premises.

             (D) The reasonable  exercise by Landlord or its agents of any right
reserved  to  Landlord  in this  Article  shall  not  constitute  an  actual  or
constructive  eviction,  in whole or in part, or entitle Tenant to any abatement
or diminution of rent, or relieve Tenant from any of its obligations  under this
lease, or impose any liability upon Landlord,  or its agents, or upon any lessor
under any ground or underlying lease, by reason of inconvenience or annoyance to
Tenant,  or  injury to or  interruption  of  Tenant's  business,  or  otherwise,
provided  the same  does  not  substantially  interfere  with  Tenant's  use and
occupancy of the Premises.

                                      -12-




                                  SUBORDINATION

         22. (A) This lease and all rights of Tenant  hereunder  are,  and shall
be,  subject  and  subordinate  in all  respects  to all  ground  leases  and/or
underlying  leases and to all first mortgages and building loan agreements which
may now or hereafter be placed on or affect such leases and/or the Real Property
of which the  Demised  Premises  form a part,  or any part or parts of such Real
Property, and/or Landlord's interest or estate therein, and to each advance made
and/or  hereafter  to be made  under any such  mortgages,  and to all  renewals,
modifications,  consolidations,  replacements  and  extensions  thereof  and all
substitutions  therefor.  This Section A shall be self-operative  and no further
instrument  of  subordination  shall  be  required.   In  confirmation  of  such
subordination,  Tenant shall execute and deliver  promptly any certificate  that
Landlord  and/or any mortgagee  and/or the lessor under any ground or underlying
lease and/or their respective  successors in interest may request, at no cost to
Tenant.

             (B) Without  limitation of any of the provisions of this lease,  in
the event that any  mortgagee  or its assigns  shall  succeed to the interest of
Landlord or of any  successor-Landlord  and/or shall have become  lessee under a
new ground or  underlying  lease,  then, at the option of such  mortgagee,  this
lease shall nevertheless  continue in full force and effect and Tenant shall and
does hereby  agree to attorn to such  mortgage  or its assigns and to  recognize
such mortgagee or its respective assigns as its Landlord.

             (C) Tenant  shall,  at any time and from time to time upon not less
that five days' prior notice by Landlord,  execute,  acknowledge  and deliver to
Landlord a statement in writing  certifying that this lease is unmodified and in
full force and effect (or if there have been modifications,  that the same is in
full force and effect as modified and stating the modification) and the dates to
which the Rent,  additional rent and other charges have been paid in advance, if
any,  and  stating  whether or not to the best  knowledge  of the signer of such
certificate  Landlord is in default in performance  of any covenant,  agreement,
term, provision or condition contained in this lease, and if so, specifying each
such default of which the signer may have knowledge,  it being intended that any
such statement  delivered  pursuant hereto may be relied upon by any prospective
purchaser or lessee of said real property or any interest or estate therein, any
mortgagee or prospective  mortgagee  thereof or any prospective  assignee of any
mortgage  thereof.  If, in connection with obtaining  financing for the Building
and  the  land  allocated  to it,  a  banking,  insurance  or  other  recognized
institutional  lender shall request reasonable  modifications in this lease as a
condition to such financing,  Tenant will not  unreasonably  withhold,  delay or
defer its consent thereof,  provided that such modifications do not increase the
obligations  of Tenant  hereunder or materially  adversely  affect the leasehold
interest hereby created.

             (D) The Tenant  covenants and agrees that if by reason of a default
under any  underlying  lease  (including an  underlying  lease through which the
Landlord  derives its leasehold  estate of the Landlord in the  premises),  such
underlying  lease and the  leasehold  estate  of the  Landlord  in the  premises
demised hereby is terminated,  providing notice has been given to the Tenant and
leasehold

                                      -13-





mortgagee,  the  Tenant  will  attorn  to the then  holder  of the  reversionary
interest in the premises demised by this Lease or to anyone who shall succeed to
the interest of the Landlord or to the lessee of a new underlying  lease entered
into pursuant to the  provisions of such  underlying  lease,  and will recognize
such  holder  and/or  such lessee as the  Tenant's  landlord of this Lease.  The
Tenant  agrees to execute and deliver,  at any time and from time to time,  upon
the request of the  Landlord or of the lessor under any such  underlying  lease,
any  instrument   which  may  be  necessary  or  appropriate  to  evidence  such
attornment.  The Tenant  further  waives the provision of any statute or rule of
law now or  hereafter in effect which may give or purport to give the Tenant any
right of election to  terminate  this Lease or to  surrender  possession  of the
premises  hereby in the event any  proceeding is brought by the lessor under any
underlying  lease to  terminate  the same,  and agrees that unless and until any
such lessor,  in connection with any such  proceeding,  shall elect to terminate
this  Lease and the  rights of the Tenant  hereunder,  this  Lease  shall not be
affected in any way whatsoever by any such proceeding,  shall elect to terminate
this  Lease and the  rights of the Tenant  hereunder,  this  Lease  shall not be
affected in any way whatsoever by any such proceeding.  Nothing herein contained
shall diminish any rights derived by reason of Nondisturbance Agreements granted
to Tenant by lessor under the terms of their underlying lease.

             (E) Landlord agrees to use good efforts to obtain a nondisturbance,
subordination and attornment agreement from its mortgagee. Tenant agrees to sign
said agreement on the form of the mortgagee.

                       PROPERTY LOSS, DAMAGE REIMBURSEMENT

         23. (A)  Landlord  or its agents  shall not be liable for any damage to
property of Tenant or of others entrusted to employees of the Building,  nor for
the loss of or damage to any property of Tenant by theft or otherwise.  Landlord
or its  agents  shall not be liable  for any  injury  or  damage to  persons  or
property  resulting  from  fire,   explosion,   falling  plaster,   steam,  gas,
electricity,  electrical disturbance, water, rain or snow or leaks from any part
of the  Building or from the pipes,  appliances  or  plumbing  works or from the
roof,  street or  subsurface  or from any other  place or by  dampness or by any
other cause of whatsoever  nature,  unless caused by or due to the negligence of
Landlord, its agents, servants or employees; nor shall Landlord or its agents be
liable for any such damage caused by other tenants or persons in the Building or
caused by  operations in  construction  of any private,  public or  quasi-public
work; nor shall Landlord be liable for any latent defect in the Demised Premises
or in the  Building.  If at any time any  windows of the  Demised  premises  are
temporarily  closed or  darkened  incident  to or for the  purpose  of  repairs,
replacements,  maintenance  and/or  cleaning in, on, to or about the Building or
any part or parts  thereof,  Landlord  shall  liable for any  damage  Tenant may
sustain  thereby and Tenant shall not be entitled to any  compensation  therefor
nor  abatement  of rent  shall  the same  release  Tenant  from its  obligations
hereunder nor  constitute  an eviction.  Tenant shall  reimburse and  compensate
Landlord as additional  rent for all  expenditures  made by, or damages or fines
sustained or incurred by Landlord due to non-performance or non-compliance  with
or breach or failure to observe any term,  covenants  or condition of this lease
upon  Tenant's part to be kept,  observed,  performed or complied  with.  Tenant
shall give  immediate  notice to  Landlord in case of fire or  accidents  in the
Demised  Premises or in the Building or of defects therein or in any fixtures or
equipment.

                                      -14-




                               TENANT'S INDEMNITY

              (B) Except  for any claim  that may be  covered  by any  insurance
provided by the Tenant to  Landlord,  as provided in Article  25(D) or any other
insurance provided by Tenant,  Tenant shall indemnify and save harmless Landlord
against  and from any and all claims by or on behalf of any  person or  persons,
firm  or  firms,  corporation  or  corporations  arising  from  the  conduct  or
management of or from any work or thing  whatsoever done (other than by Landlord
or its  contractors  or the agents or employees of either) in and on the Demised
Premises  during the term of this  lease and  during the period of time,  if any
prior to the specified  commencement date that Tenant may have been given access
to the  Demised  Premises  for the  purpose  of making  installations,  and will
further indemnify and save harmless Landlord against and from any and all claims
arising from any  condition  of the Demised  Premises due to or arising from any
act or  omissions  or  negligence  of Tenant or any of its agents,  contractors,
servants,  employees,  licensees  or  invitees  and  against and from all costs,
expenses,  and liabilities  incurred in connection with any such claim or claims
or action or proceeding brought thereon; and in case any action or proceeding be
brought against Landlord by reason of any such claim,  Tenant,  upon notice from
Landlord,  agrees that Tenant, at Tenant's  expense,  will resist or defend such
action or proceeding and will employ counsel therefor reasonably satisfactory to
Landlord.

                      DESTRUCTION -- FIRE OR OTHER CASUALTY

         24. (A) If the Premises or any part thereof shall be damaged by fire or
other  casualty  and Tenant gives prompt  notice  thereof to Landlord,  Landlord
shall proceed with  reasonable  diligence to repair or cause to be repaired such
damage. The Rent shall be abated to the extent that the Premises shall have been
rendered  untenantable,  such  abatement  to be from the date of such  damage or
destruction to the date the Premises shall be substantially repaired or rebuilt,
in  proportion  which  the  area  of  the  part  of  the  Premises  so  rendered
untenantable bears to the total area of the Premises.

              (B) If the Premises  shall be totally  damaged or rendered  wholly
untenantable  by fire or other  casualty,  and Landlord has not terminated  this
lease  pursuant of  Subsection  (C) and Landlord has not completed the making of
the required repairs and restored and rebuilt the Premises and/or access thereto
within  nine (9) months from the date of such  damage or  destruction,  and such
additional  time after such date (but in no event to exceed six (6) months),  as
shall equal the aggregate  period  Landlord may have been delayed in doing so by
unavoidable  delays or  adjustment  of  insurance,  Tenant  may serve  notice on
Landlord of its intention to terminate  this lease,  and within thirty (30) days
thereafter  Landlord shall not have completed the making of the required repairs
and  restored  and  rebuilt the  Premises,  this lease  shall  terminate  on the
expiration of such thirty (30) day period as if such  termination  date were the
Expiration  Date, and the Rent and additional rent shall be refunded by Landlord
to Tenant.

                                      -15-





              (C) If the premises  shall be totally  damaged or rendered  wholly
untenantable by fire or other casualty or if the Building shall be so damaged by
fire or other  casualty that  substantial  alteration or  reconstruction  of the
Building shall, in Landlord's  opinion, be required (whether or not the Premises
shall been damaged by such fire or other  casualty),  then in any of such events
Landlord may, at its option, terminate this lease and the Term and estate hereby
granted,  by giving  Tenant thirty (30) days notice of said  termination  within
thirty (30) days after the date of such damage. In the event that such notice of
termination  shall be given,  this lease and the term and estate hereby granted,
shall  terminate as of the date provided in such notice of termination  (whether
or not the Term shall have  commenced)  with the same effect as if that were the
Expiration Date, and the Rent and additional rent shall be apportioned as of the
date of the fire or destruction or sooner  termination,  and any prepaid portion
of Rent and additional  rent for any period after such date shall be refunded by
Landlord to Tenant.

              (D)  Landlord  shall  not  be  liable  for  any  inconvenience  or
annoyance  to Tenant or injury to the  business of Tenant  resulting  in any way
from such damage by fire or other casualty or the repair thereof.  Landlord will
not carry insurance of any kind on Tenant's property,  and Landlord shall not be
obligated to repair any damage thereto or replace the same.

              (E) This lease shall be considered an express agreement  governing
any case of damage to or destruction of the Building or any part thereof by fire
or other casualty,  and Section 227 of the Real Property Law of the State of New
York providing for such a contingency in the absence of such express  agreement,
and any  other  law of like  import  nor or  hereafter  enacted,  shall  have no
application in such case.

              (F)  Notwithstanding  anything to the contrary elsewhere contained
herein,  if the Premises or the building  containing  the same are so damaged or
rendered  untenantable  by fire or  other  casualty  that the  Landlord,  in the
Landlord's good faith estimate,  cannot complete repairs or rebuild the Premises
to a condition to restore  possession  of the same so that the Tenant may resume
its  business  therein  within one  hundred  twenty  (120) days of the damage or
destruction,  then the  Tenant is hereby  given an option to cancel  this  lease
without  penalty,  within  fifteen (15) days of receipt of Landlord's  Notice by
written notice to Landlord.  The Landlord shall deliver the aforesaid good faith
estimate of repairs or rebuilding  time within thirty (30) days from the date of
damage or destruction.

                                    INSURANCE

       25.    (A) Tenant shall not do anything,  or suffer or permit anything to
do done in or about  the  Premises  which  shall  (a)  subject  Landlord  to any
liability  or  responsibility  for injury to any person or property by reason of
any  activity  being  conducted in the Premises or (b) cause any increase in the
fire insurance  rates  applicable to the Building or equipment or other property
located therein at the beginning of the Term or at any time thereafter.  Tenant,
at  Tenant's  expense,  shall  comply  with all rules,  orders,  regulations  or
requirements  of the New York Board of Fire  Underwriters  and the New York Fire
Insurance Rating Organization or any similar body.

              (B) If,  by  reason  of any  act or  omission  on the  part of the
Tenant,  the rate of fire  insurance  with extended  coverage on the Building or
equipment  or other  property of  Landlord or another  tenant or occupant of the
Building  shall be higher than it otherwise  would be,  Tenant  shall  reimburse
Landlord and all such other tenants or occupants on demand, for that part of the
premises  for fire  insurance  and extended  coverage  paid by Landlord and such
other tenants or occupants because of an act or omission on the part of Tenant.

                                      -16-




              (C) In the event that any dispute  should arise  between  Landlord
and Tenant concerning  insurance rates, a schedule or make up or insurance rates
for the  Building or the  Premises,  as the case may be,  issued by the New York
Fire Insurance  Rating  Organization or other similar body making rates for fire
insurance and extended coverage for the Premises concerned,  shall be conclusive
evidence of the facts therein stated and of the several items and charges in the
fire insurance rates with extended coverage then applicable to such Premises.

              (D) Tenant shall  obtain and keep in full force and effect  during
Term,  at its own  cost  and  expense,  (a)  Public  Liability  Insurance,  such
insurance  to afford  protection  in an amount  of not less than  Three  Million
($3,000, 000) Dollars for injury or death arising out of any one occurrence, and
Five Hundred  Thousand  ($500,000)  Dollars for damage to  property,  protecting
Landlord  and Tenant as named  insureds  against any and all claim for  personal
injury,  death or property damage occurring in, upon,  adjacent to, or connected
with the Premises or any part thereof;  and (b) insurance against loss or damage
by fire,  and such other risks and hazards as are  insurable  under  present and
future  standard  forms of fire and extended  coverage  insurance  policies,  to
Tenant's property for the full insurable value thereof,  protecting Landlord and
Tenant as named insured.

              (E)  Said  insurance  is to  be  written  in  form  and  substance
reasonably  satisfactory to Landlord by a good and solvent  insurance company of
recognized standing,  admitted to do business in the State of New York and rated
as "good" in Bests Insurance Rating Manual.  Tenant shall procure,  maintain and
place such insurance and pay all premiums and charges  therefor and upon failure
to do so Landlord  may, but shall not be  obligated  to,  procure,  maintain and
place such insurance or make such payments,  and in such event the Tenant agrees
to pay the amount thereof,  plus interest at the legal rate then prevailing,  to
Landlord  on  demand  and said  sum  shall be in each  instance  collectible  as
Additional  Rent on the first day of the month  following the date of payment by
Landlord.  Tenant  shall cause to be included in all such  insurance  policies a
provision to the effect that the same will be non-cancellable except upon twenty
(20) days written  notice to  Landlord.  On the  Commencement  Date the original
insurance policies or appropriate certificates shall be deposited with Landlord.
Any renewals,  replacements or endorsements thereto shall also be deposited with
Landlord to the end that said insurance shall be in full force and effect during
the Term.

              (F) Each party  agrees to use its best  efforts to include in each
of its  insurance  policies  (insuring  the  Building  and  Landlord's  property
therein, in the case of Landlord, and insuring Tenant's property, in the case of
Tenant,  against loss, damage or destruction by fire or other casualty) a waiver
of the insurer's right of subrogation against the other party, or if such waiver
should be  unobtainable  or  unenforceable  (a) an express  agreement  that such
policy shall not be  invalidated  if the assured waives or has waived before the
casualty  the right of  recovery  against any party  responsible  for a casualty
covered by the policy,  or (b) any other form of  permission  for the release of
covered by the policy, or (b) any other form of permission or the release of the
other party,  or (c) the inclusion of the other party as an additional 

                                      -17-





insured,  but not a party to whom any loss  shall be  payable.  If such  waiver,
agreement or permission shall not be, or shall cease to be,  obtainable  without
additional  charge or at all, the insured  party shall so notify the other party
promptly after learning thereof. In such case, if the other party shall agree in
writing to pay the insurer's additional charge therefor, such waiver,  agreement
or permission shall be included in the policy, or the other party shall be named
as an additional  assured in the policy,  but not a party to whom any loss shall
be payable. Each such policy which shall so name a party hereto as an additional
assured shall contain, if obtainable,  agreements by the insurer that the policy
will not be  cancelled  without a least  twenty  (20) days prior  notice to both
assured  and that the act or omission of one  assured  will not  invalidate  the
policy as to the other assured.

              (G) As long as Landlord's  fire  insurance  policies then in force
include  the  waiver of  subrogation  or  agreement  or  permission  to  release
liability  referred  to in  Subsection  (F) or name the Tenant as an  additional
assured, Landlord hereby waives (a) any obligation on the part of Tenant to make
repairs to the Premises  necessitated  or occasioned  by fire or other  casualty
that is an  insured  risk  under such  policies,  and (b) any right of  recovery
against Tenant, any other permitted  occupant of the Premises,  and any of their
servants,  employees, agents or contractors,  for any loss occasioned by fire or
other casualty that is an insured risk under such policies. In the event that at
any time  Landlord's  fire insurance  carriers shall not include such or similar
provisions in Landlord's fire insurance  policies,  the waivers set forth in the
foregoing sentence shall be deemed of no further force or effect.

             (H) As long as  Tenant's  fire  insurance  policies  then in  force
include  the  waiver of  subrogation  or  agreement  or  permission  to  release
liability  referred to in Subsection  (F), or name the Landlord as an additional
assured Tenant hereby waives (and agrees to cause any other permitted  occupants
of the Premises to execute and deliver to Landlord written instruments  waiving)
any right of recovery  against  Landlord,  any other tenants or occupants of the
Building, and any servants,  employees,  agents or contractors of Landlord or of
any such other  tenants or occupants,  for any loss  occasioned by fire or other
casualty  which is an insured risk under such polices.  In the event that at any
time  Tenant's  fire  insurance  carriers  shall  not  include  such or  similar
provisions  in Tenant's  fire  insurance  policies,  the waiver set forth in the
foregoing sentence shall, upon notice given by Tenant to Landlord,  be deemed of
no further  force or effect with respect to any insured  risks under such policy
from and after the giving of such notice.  During any period while the foregoing
waiver  of right of  recovery  is in  effect,  Tenant,  or any  other  permitted
occupant of the Premises,  as the case maybe,  shall look solely to the proceeds
of such policies to compensate  Tenant or such other  permitted  occupant of the
Premises,  as the case may be,shall look solely to the proceeds of such policies
to compensate Tenant or such other permitted occupant for any loss occasioned by
fire or other casualty which is an insured risk under such policies.

                                 EMINENT DOMAIN

        26.   (A) In the event that the whole of the Demised  Premises  shall be
lawfully  condemned or taken in any manner for any public or  quasi-public  use,
this lease and the Term and estate  hereby  granted  shall  forthwith  cease and
terminate  as of the date of vesting of title.  In the event that only a part of
the Demised  Premises  shall be so condemned or taken,  then effective as of the
date of  vesting  of  title,  the Rent  hereunder  shall be  abated in an amount
thereof  apportioned  according to the area of the Demised Premises so condemned
or taken. In the event that only a part of the Building shall be so condemned or
taken,  then (a) Landlord (whether or not the Demised Premised be affected) may,
at its option, terminate this lease and the Term and estate hereby granted as of
the date of such  vesting  of title  by  notifying  Tenant  in  writing  of such
termination  within sixty (60) days  following the date on which  Landlord shall
have received notice of vesting of title, and (b) if such condemnation or taking
shall be of a substantial  part of the Demised Premises or a substantial part of
the means of access  thereof,  Tenant shall have the right by delivery of notice
in writing to Landlord within sixty (60) days following the date on which Tenant
shall have received  notice of vesting of title to terminate  this lease and the
Term and estate  hereby  granted  as of the date of vesting of title,  or (c) if
neither  Landlord nor Tenant elect to terminate this lease,  as aforesaid,  this
lease shall be and remain unaffected by such condemnation or taking, except that
the Rent shall be and remain unaffected by such  condemnation or taking,  except
that the Rent shall be abated to the  extent,  if any,  hereinabove  provided in
this Article 26. In the event that only a part of the Demised  Premised shall be
so condemned or taken and this lease and the Term and estate hereby  granted are
not terminated as hereinbefore  provided  Landlord will at its expense,  restore
the remaining  portion of the Demised  Premises as nearly as  practicable to the
same condition as it was in prior to such condemnation or taking.

              (B) In the event of a termination in any of the cases  hereinabove
provided, this lease and the Term and estate granted shall expire as of the date
of such termination  with the same effect as if that were the date  hereinbefore
set for the expiration of the Term of this lease,  and the rent hereunder  shall
be apportioned as of such date.

              (C) In  the  event  of  any  condemnation  or  taking  hereinabove
mentioned  of all or a part of the  Building,  Landlord  shall  be  entitled  to
receive the entire award in the  condemnation  proceeding,  including  any award
made for the value of the  estate  vested by this  lease in  Tenant,  and Tenant
hereby  expressly  assigns to Landlord any and all right,  title and interest of
Tenant now or hereafter arising in or to any such award or any part thereof, and
Tenant  shall be  entitled  to receive no part of such  award,  except  that the
Tenant may file a claim for any taking of  nonmovable  fixtures  owned by Tenant
and for moving  expenses  incurred by Tenant.  It is  expressly  understood  and
agreed that the  provisions  of this Article 26 shall not be  applicable  to any
condemnation or taking for governmental occupancy for a limited period.


                                      -19-

                            NONLIABILITY OF LANDLORD

         27. (A) If Landlord or a successor in interest is an individual  (which
term as used herein includes aggregates of individuals,  such as joint ventures,
general or limited  partnerships or associations) such individual shall be under
no personal  liability with respect to any of the provisions of this Lease,  and
if  such  individual  hereto  is in  breach  or  default  with  respect  to  its
obligations  under this  lease,  Tenant  shall look solely to the equity of such
individual  in the land and Building of which the Demised  Premises  form a part
for the  satisfaction of Tenant's  remedies and in no event shall Tenant attempt
to secure any  personal  judgment  against  any  partner,  employee  or agent of
Landlord by reason of such default by Landlord.

                  (B) The word "Landlord" as used herein means only the owner in
fee for the time being of the land and Building (or the owners of a lease of the
Building or of the land and Building) of which the Premises form a part,  and in
the event of any sale of the  Building  and land of which the  Demised  Premises
form a part,  Landlord shall be and hereby is entirely freed and relieved of all
covenants  and  obligations  of  Landlord  hereunder  and it shall be deemed and
construed  without further  agreement between the parties or between the parties
and the purchaser of the Premises, that such purchaser has assumed and agreed to
carry out any and all covenants and obligations of Landlord hereunder.

                                     DEFAULT

         28. (A) Upon the occurrence, at any time prior to or during the Demised
Term,  of any one or more of the  following  events  (referred  to as "Events of
Default"):

                  (i) If Tenant  shall  default in the  payment  when due of any
installment of Rent or in the payment when due of any additional  rent, and such
default  shall  continue  for a period of (5) days after  notice by  Landlord to
Tenant of such default; or

                  (ii) If Tenant shall  materially  default in the observance or
performance of any term, covenant or condition of this lease on Tenant's part to
be observed or performed  (other than the  covenants for the payment of Rent and
additional  rent) and Tenant shall fail to remedy such  default  within ten (10)
days after  notice by Landlord to Tenant  specifying  such  default,  or if such
default is of such a nature that it cannot be  completely  remedied  within said
period of ten (10) days and Tenant shall not commence  within said period of ten
(10) days, or shall not thereafter diligently prosecute to completion, all steps
necessary to remedy such default; or

                  (iii) If Tenant shall file a voluntary  petition in bankruptcy
or insolvency,  or shall be adjudicated a bankrupt or become insolvent, or shall
file any petition or answer seeking any reorganization, arrangement,

                                      -20-

composition, readjustment,  liquidation, dissolution or similar relief under the
present  or any future  federal  bankruptcy  act or any other  present or future
applicable  federal,  state or other statute of law, or shall make an assignment
for the benefit of creditors  or shall seek or consent to or make an  assignment
for the benefit of  creditors  or shall seek or consent to or  acquiesce  in the
appointment  of any trustee,  receiver or  liquidator of Tenant or of all or any
part of Tenant's property; or

         (iv)  If,  within  sixty  (60)  days  after  the  commencement  of  any
proceeding  against  Tenant,  whether by the filing of a petition  or  otherwise
seeking any reorganization, arrangement, composition, readjustment, liquidation,
dissolution or similar relief under the present or any future federal bankruptcy
act or any other present or future applicable federal, state or other statute or
law, such  proceedings  shall not have been dismissed,  or if, within sixty (60)
days after the appointment or any trustee,  receiver or liquidator of Tenant, or
of all or any part of Tenant's property,  without the consent or acquiescence of
Tenant, such appointment shall not have been vacated or otherwise discharged, or
if any execution or attachment shall be issued against Tenant or any of Tenant's
property  pursuant to which the Demised  Premises  shall be taken or occupied or
attempted to be taken or occupied; or

         (v) If the Demised Premises shall become vacant,  deserted or abandoned
for a period of ten (10) consecutive days; or

         (vi) If Tenant's  interest in this lease shall  devolve upon or pass to
any  person,  whether by  operation  of law or  otherwise,  except as  expressly
permitted under Article 20.

Then , upon the occurrence,  at any time prior to or during the Demised Term, of
any one or more of such Events of Default,  Landlord, at any time thereafter, at
Landlord's  option, may give to Tenant a five (5) days' notice of termination of
this lease and, in the event such notice is given, this lease and the Term shall
come to an end and expire  (whether or not said term shall have  commenced) upon
the  expiration  of said  five(5)  days  with the same  effect as if the date of
expiration  of said five (5) days were the  Expiration  Date,  but Tenant  shall
remain liable for damages as provided in Article 30.

         (B) If, at any time (i) Tenant  shall be  comprised  of two (2) or more
persons,  or  (ii)  Tenant's  obligations  under  this  lease  shall  have  been
guaranteed by any person other than Tenant,  or (iii) Tenant's  interest in this
lease shall have been assigned,  the word "Tenant",  as used in subsection (iii)
and (iv) of section 28A,  shall be deemed to mean any one or more of the persons
primarily or secondarily  liable for Tenant's  obligations under this lease. Any
monies received by Landlord from or on behalf of Tenant during the pendency of

                                      -21-

any proceeding of the types referred to in said subsections (iii) and (iv) shall
be  deemed  paid as  compensation  for the use  and  occupation  of the  Demised
Premises and the  acceptance of any such  compensation  by Landlord shall not be
deemed an  acceptance  of Rent or a waiver on the part of Landlord of any rights
under section 28(A).

                             TERMINATION ON DEFAULT

         29.  (A) If  Tenant  shall  default  in  the  payment  when  due of any
installment of rent or in the payment when due of any  additional  rent and such
default shall  continue for a period of five (5)days after notice by Landlord to
Tenant of such  default,  or if this lease and the demised term shall expire and
come to an end as provided in Article 28:

                 (i) Landlord and its agents and servants may immediately, or at
any time  after  such  default  or after the date upon  which this lease and the
Demised Term shall expire and come to an end,  re-enter the Demised  Premises or
any part thereof,  without notice, either by summary proceedings or by any other
applicable action or proceeding,  or by force or otherwise (without being liable
to indictment,  prosecution or damages therefor),  and may repossess the Demised
Premises and dispossess  tenant and any other persons from the Demised  Premises
and remove any and all of their property and effects from the Demised  Premises;
and

               (ii) Landlord,  at Landlord's  option, may relet the whole or any
part or parts of the Demised  Premises from time to time,  either in the mane of
Landlord or otherwise,  to such tenant or tenants, for such term or terms ending
before, on or after the Expiration Date, at such rental or rentals and upon such
other  conditions,  which may  include  concessions  and free rent  periods,  as
Landlord,  in its  sole  discretion,  may  determine.  Landlord  shall  have  no
obligation  to relet the Demises  Premises  or any part  thereof and shall in no
event be liable for refusal or failure to relet the Demised Premises or any part
thereof,  or in the event of any such reletting,  and no such refusal or failure
shall operate to relieve  Tenant of any liability  under this lease or otherwise
to affect any such  liability;  Landlord,  at Landlord's  option,  may make such
repairs,  replacements,  alterations,  additions,  improvements,  decoration and
other physical changes in and to the Demised  Premises as Landlord,  in its sole
discretion,  considers  advisable  or  necessary  in  connection  with  any such
reletting or proposed reletting, without relieving Tenant of any liability under
this lease or otherwise affecting any such liability.

               (B)  Tenant,  on its own  behalf  and on  behalf  of all  persons
claiming through or under Tenant, including all creditors, does hereby waive any
and all rights which Tenant and all such persons might  otherwise have under any
present  or  future  law to redeem  the  Demised  Premises,  or to  re-enter  or
repossess the Demised Premises, or to restore the operation of this lease, after
(i) Tenant shall have been dispossessed by a judgment or by warrant of any court
or judge,

                                      -22-

or (ii) any re-entry by Landlord, or (iii) any expiration or termination of this
lease and the Demised term,  whether such  dispossess,  re-entry,  expiration or
termination  shall be by operation of law or pursuant to the  provisions of this
lease.  In the event of a breach or  threatened  breach by Tenant or any persons
claiming  through or under Tenant,  of any term,  covenants or condition of this
lease on  Tenant's  part to be observed or  performed,  Landlord  shall have the
right to enjoin such breach and the right to invoke any other remedy  allowed by
law or in equity as if re-entry,  summary proceedings and other special remedies
were not  provided  in this  lease for such  breach.  The  rights to invoke  the
remedies  hereinbefore set forth are cumulative and shall not preclude  Landlord
from invoking any other remedy allowed at law or in equity.

                                     DAMAGES

         30. (A) If this lease and the demised  term shall expire and come to an
end as  provided  in Article 28 or by or under any  summary  proceeding,  or any
other action or proceeding or if Landlord shall re-enter the Demised Premises as
provided  in  Article  29 or by or under any  summary  proceedings  or any other
action or proceeding, then, in any of said events:

                 (i) Tenant shall pay to Landlord all Rent,  additional rent and
other  charges  payable  under this lease by Tenant to Landlord to the date upon
which this lease and the Demised  Term shall have  expired and come to an end or
to the date of re-entry upon the Demised  Premises by Landlord,  as the case may
be; and

                  (ii)Tenant shall also be liable for and shall pay to Landlord,
as damages,  any deficiency  (referred to as "Deficiency")  between the rent and
additional rent reserved in this lease for the period which otherwise would have
constituted  the  unexpired  portion of the Demised Term and the net amount,  if
any, of rents collected under any reletting  effected pursuant to the provisions
of section  29(A) for any part of such period  (first  deducting  from the rents
collected under any such reletting all of Landlord's expenses in connection with
the termination of this lease or Landlord's  re-entry upon the Demised  Premises
and with such reletting  including,  but not limited to, all repossession costs,
brokerage  commissions  for the balance of the Demised Term,  for the balance of
the Demised Term, legal expenses,  attorney's  fees,  alteration costs and other
expenses  of  preparing  the  Demised  Premises  for such  reletting).  Any such
Deficiency shall be paid in monthly installments by tenant on the days specified
in this lease for payment of installments of Rent, Landlord shall be entitled to
recover form Tenant each monthly Deficiency as the same shall arise, and no suit
to collect the amount of the Deficiency for any month shall prejudice Landlord's
rights  to  collect  the  Deficiency  for  any  subsequent  month  by a  similar
proceeding; and

             (iii) At any time after the  Demised  Term shall have  expired  and
come to an end or Landlord shall have re-entered upon the Demised  Premises,  as
the case may be,  whether or not  Landlord  shall  have  collected  any  monthly
Deficiencies as aforesaid, Landlord shall be entitled to recover from Tenant,

                                      -23-



and Tenant shall pay to Landlord,  on demand,  as and for  liquidated and agreed
final damages,  a sum equal to the amount by which the rent and additional  Rent
reserved in this lease for the period which otherwise would have constituted the
unexpired  portion of the  Demised  Term  exceeds  the then fair and  reasonable
rental value of the Demised  Premises for the same period,  both  discounted  to
present  worth  at the  rate of  four  (4%)  per  cent  per  annum.  If,  before
presentation of proof of such liquidated  damages to any court,  commission,  or
tribunal,  the Demised Premises,  or any part thereof,  shall have been relet by
Landlord for the period which  otherwise  would have  constituted  the unexpired
portion of the Demised Term,  or any part  thereof,  the amount of Rent reserved
upon such reletting shall be deemed,  prima facie, to be the fair and reasonable
rental  value for the part of the whole of the Demised  Premises so relet during
the time of the reletting.

         (B) If the  demised  Premises,  or any  part  thereof,  shall  be relet
together with other space in the Building, the rents collected or reserved under
any such  reletting  and the expenses of any such  reletting  shall be equitably
apportioned  for the  purposes of this  Article 30.  Tenant shall in no event be
entitled to any rents  collected or payable under any reletting,  whether or not
such rents shall exceed the rent reserved in this lease. Solely for the purposes
of this Article, the term "Rent" as used in Section 30(A) shall mean the rent in
effect  immediately prior to the date upon which this lease and the Demised Term
shall have  expired and come to an end or the date of re-entry  upon the Demised
Premises by  Landlord,  as the case may be,  plus any  additional  rent  payable
pursuant to the provisions of Article 11 of the  Escalation  Year (as defined in
Article 11) immediately  preceding such event.  Nothing  contained in Article 28
and 29 of this  Lease  shall be  deemed to limit or  preclude  the  recovery  by
Landlord from Tenant of the maximum  amount allowed to be obtained as damages by
any statute or rule of law, or of any sums or damages to which  Landlord  may be
entitled in addition to the damages set forth in Section 30(A).

                                SUMS DUE LANDLORD

         31. In any case in which the Rent or additional rent is not paid within
ten (10) days of the day when same is due,  tenant shall pay a late charge equal
to 6 cent for each dollar so due,  and in addition  thereto,  the sum of $100.00
for  the  purpose  of  defraying  expenses  incident  to the  handling  of  such
delinquent account. The provisions for payment of late charges shall be forgiven
once in every calendar year.  Tenant further agrees that the late charge imposed
is fair and reasonable,  complies with all laws,  regulations and statutes,  and
constitutes an agreement between Landlord and Tenant as to the

                                      -24-

compensation for costs and  administrative  expenses incurred by Landlord due to
the late payment of rent to Landlord by tenant.  Tenant  further agrees that the
late charge assessed pursuant to this lease is not interest, and the late charge
assessed does not constitute a lender or borrower/creditor  relationship between
Landlord and Tenant.

                                    NO WAIVER

         32. No act or thing done by Landlord or  Landlord's  agents  during the
term hereby Demised shall be deemed an acceptance of a surrender of said demised
Premises,  and no  agreement to accept such  surrender  shall be valid unless in
writing signed by Landlord. No employee of Landlord or of Landlord's agent shall
have  any  power  to  accept  the  keys of said  Demised  Premises  prior to the
termination  of this lease.  The delivery of keys to any employee of Landlord or
of  Landlord's  agents  shall not  operate as a  termination  of this lease or a
surrender of the Demise Premises. In the event of Tenant at any time desiring to
have Landlord  underlet the demised Premises for Tenant's  account,  Landlord or
Landlord's agents are authorized to received said keys for such purposes without
releasing Tenant from any of the obligations under this lease, and Tenant hereby
relieves  Landlord  of any  liability  for loss of or damage  to any of  Tenants
effects in connections with such  underletting.  The failure of Landlord to seek
redress  for  violation  of, or to insist  upon the strict  performance  of, any
covenants  or  conditions  of this  lease,  or any of the Rules and  Regulations
annexed  hereto and made a part hereof or hereafter  adopted by Landlord,  shall
not  prevent a  subsequent  act,  which  would  have  originally  constituted  a
violation,  from having all the force and effect of an original  violation.  The
receipt by Landlord of rent with knowledge of the breach of any covenant of this
lease  shall not be deemed a waiver of such  breach.  The failure of Landlord to
enforce any of the Rules and Regulations  annexed hereto and made a part hereof,
or hereafter  adopted,  against  Tenant  and/or any other tenant in the Building
shall not be deemed a waiver of any such Rules and Regulations.  No provision of
this lease shall be deemed to have been waived by  Landlord,  unless such waiver
be in writing signed by Landlord. No payment by Tenant or receipt by Landlord of
a lesser  amount then the monthly Rent herein  stipulated  shall be deemed to be
other than on account of the earliest  stipulated Rent nor shall any endorsement
or  statement  on any check or any letter  accompanying  any check or payment as
Rent be deemed an accord and satisfaction, and Landlord may accept such check or
payment  without  prejudice to  Landlords'  right to recover the balance of such
Rent or pursue any other remedy in this lease provided.

                                      -25-

         33. To the extent such waiver is permitted by law,  Landlord and Tenant
hereby waive trial by jury in any action,  proceeding or counterclaim brought by
Landlord or Tenant against the other on any matter whatsoever  arising out of or
in any way connected with this lease,  the  relationship of landlord and tenant,
the use or  occupancy of the Demised  Premises by Tenant or any person  claiming
through or under  Tenant,  any claim of injury or damage,  and any  emergency or
other statutory remedy.  The provisions of the foregoing  sentence shall survive
the  expiration  or any sooner  termination  of the  Demised  Term.  If Landlord
commences any summary  proceeding for  nonpayment of Rent,  Tenant agrees not to
interpose  any  counterclaim  of  whatever  nature  or  description  in any such
proceeding.

         Tenant hereby expressly waives any and all rights of redemption granted
by or under any present or future laws in the event of Tenant  being  evicted or
dispossessed for any cause, or in the event of Landlord's  obtaining  possession
of the  Demised  Premises,  by reason of the  violation  by Tenant of any of the
covenants and conditions of this Lease or otherwise.

                                BILL AND NOTICES

         34. Except as otherwise  expressly  provided in this lease,  any bills,
statements, notices, demands, requests or other communications given or required
to be given  under this lease  shall be  effective  only if rendered or given in
writing,  sent by  registered  or  certified  mail (return  receipt  requested),
addressed  (A) to Tenant  (i) at  Tenant's  address  set forth in this  lease if
mailed prior to Tenant's taking possession of the Demised  Premises,  or (ii) at
the Building if mailed  subsequent to Tenant's taking  possession of the Demised
Premises,  or (iii) at any place where Tenant or any agent or employee of Tenant
may be found if mailed subsequent to Tenant's vacating, deserting, abandoning or
surrendering the Demised Premises,  or (B) to Landlord at Landlord's address set
forth in this lease,  or (C) addressed to such other address as either  Landlord
or Tenant may  designate  as its new address for such purpose by notice given to
the other in accordance  with the  provisions  of this Article.  Any such bills,
statements,  notices,  demands, requests or other communications shall be deemed
to have been  rendered  or given on the date when it shall  have been  mailed as
provided in this Article.

                              INABILITY TO PERFORM

         35. (A) If, by reason of strikes or other labor disputes, fire or other
casualty (or reasonable delays in adjustments of insurance), accidents, orders

                                      -26-



or  regulations of any Federal,  State,  County or Municipal  authority,  or any
other cause  beyond  Landlord's  reasonable  control,  whether or not such other
cause shall be similar in nature to those hereinbefore  enumerated,  Landlord is
unable to furnish or is delayed in furnishing any utility or service required to
be furnished by Landlord  under the  provisions of this lease or any  collateral
instrument,  or is unable to  perform or make or is  delayed  in  performing  or
making  any  installations,  decorations,  repairs,  alterations,  additions  or
improvements,  whether or not required to be performed or made under this lease,
or under any  collateral  instrument,  or is unable to  fulfill or is delayed in
fulfilling  any  of  Landlord's  other  obligations  under  this  lease,  or any
collateral instrument,  no such inability or delay shall constitute an actual or
constructive eviction, in whole or in part or entitle Tenant to any abatement or
diminution of rent,  or relieve  Tenant from any of its  obligations  under this
lease,  or  impose  any  liability  upon  Landlord  or its  agents  by reason of
inconvenience  or annoyance to Tenant,  or injury to or interruption of Tenant's
business,  or  otherwise.  Notwithstanding  anything to the  contrary  elsewhere
contained  herein,  the Landlord  covenants that it will use its best efforts to
restore  service  to the  Premises  or  remedy  the  conditions  as  soon  as is
reasonably possible.

                             INTERRUPTION OF SERVICE

         (B)  Landlord  reserves  the  right  to stop  the  services  of the air
conditioning,  elevator,  plumbing,  electrical or other  mechanical  systems or
facilities in the building when necessary by reason of accident or emergency, or
for repairs, alterations,  replacements or improvements, which, in the judgement
of  Landlord  are  desirable  or  necessary,  until said  repairs,  alterations,
replacements or improvements shall have been completed.  Landlord agrees to give
Tenant reasonable notice of any interruption of service, except in an emergency.
The  exercise  of such  rights by  Landlord  shall not  constitute  an actual or
constructive  eviction,  in whole or in part, or entitle Tenant to any abatement
or diminution or rent, or relieve Tenant from any of its obligations  under this
lease,  or  impose  any  liability  upon  Landlord  or its  agents  by reason of
inconvenience  or annoyance to Tenant,  or injury to or interruption of Tenant's
business or otherwise.

                       CONDITIONS OF LANDLORD'S LIABILITY

         (C) (i) Tenant shall not be entitled to claim a  constructive  eviction
from the Demised  Premises  unless Tenant Shall have first notified  Landlord of
the  condition or  conditions  giving rise  thereto,  and if the  complaints  be
justified,  unless Landlord shall have failed to remedy such conditions within a
reasonable time after receipt of such notice.

              (ii) If Landlord shall be unable to give possession of the Demised
Premises on any date specified for the commencement of the term by

                                      -27-

reason of the fact that the  Premises  have not been  sufficiently  completed to
make the premises ready for occupancy,  or for any other reason,  Landlord shall
not be subject to any liability for the failure to give possession on said date,
nor shall  such  failure in any way  affect  the  validity  of this lease or the
obligations of Tenant hereunder.

                           TENANT'S TAKING POSSESSION

         (D) (i) Tenant by entering  into  occupancy  of the  Premises  shall be
conclusively  deemed  to  have  agreed  that  Landlord  up to the  time  of such
occupancy had performed all of its  obligations  hereunder and that the Premises
were in satisfactory  condition as of the date of such occupancy,  unless within
thirty  (30) days after such date  Tenant  shall  have given  written  notice to
Landlord specifying the respects in which the same were not in such condition.

                  (ii) If  Tenant  shall  use or  occupy  all or any part of the
Demised  Premises  for the  conduct of business  prior to the Term  Commencement
Date,  such use or  occupancy  shall be  deemed  to be under  all of the  terms,
covenants and  conditions of this lease,  including the covenant to pay rent for
the  period  from  the  commencement  of  said  use or  occupancy  to  the  Term
Commencement Date.

                  (iii) In the event  Landlord does not  substantially  complete
the  Premises  by March 30,  1992,  plus such  additional  time caused by Tenant
Delays,  Tenant  shall  have the  right to serve a  fifteen  (15) day  notice of
termination.  In the event the Premises are not  substantially  completed within
said  fifteen  (15) days,  this lease shall be null and void and  neither  party
shall have any further rights or obligations to the other.

                                ENTIRE AGREEMENT

         36. This lease  (including the Schedules and Exhibits  annexed  hereto)
contains the entire agreement between the parties and all prior negotiations and
agreements  are  merged  herein.   Neither  Landlord  nor  Landlord's  agent  or
representative  has made any  representations or statements,  or promises,  upon

representation  or promise as to the  fitness of the  Demised  Premises  for any
particular  use,  the  services to be  rendered  to the Demised  Premises or the
prospective amount of any item of additional rent. No oral or written statement,
representation or promise  whatsoever with respect to the foregoing or any other
matter made by  Landlord,  its agents or any  broker,  whether  contained  in an
affidavit, information circular, or otherwise shall be binding upon the Landlord
unless  expressly set forth in this lease. No rights,  easements or licenses are
or shall be acquired by Tenant by implication or otherwise  unless expressly set
forth in this lease. This lease may not be changed,  modified or discharged,  in
whole or in part,  orally  and no  executory  agreement  shall be  effective  to
change, modify or discharge,  in whole or in part, this lease or any obligations
under this lease,  unless such  agreement  is set forth in a written  instrument
executed by the party against whom  enforcement of the change,  modification  or
discharge is sought.  All references in this lease to the consent or approval of
Landlord shall be deemed to mean

                                      -28-

the written  consent of Landlord,  or the written  approval of Landlord,  as the
case may be, and no consent or approval of Landlord  shall be effective  for any
purpose  unless such  consent or  approval is set forth in a written  instrument
executed by Landlord.

         38. If  Tenant is a  partnership  (or is  comprised  of two (2) or more
persons,  individually  and as  co-partners  of a  partnership)  or if  Tenant's
interest in this lease shall be assigned to a partnership (or to two (2) or more
persons,  individually and as co-partners of a partnership)  pursuant to Article

of all of the terms,  covenants and conditions of this lease on Tenant's part to
be observed and performed  (but neither  Landlord's  failure to request any such
agreement nor the failure of any such new partner to execute or deliver any such
agreement to Landlord shall vitiate the  provisions of  subdivision  (d) of this
Section).

                                 RENEWAL OPTION

provided, to extend the term of this Lease for one period of five (5) years upon
the following terms and conditions:

                  (A) That at the time of the  exercise of such right the Tenant
shall  not be in  default  in the  performance  of  any of the  material  terms,
covenants or conditions  herein  contained  with respect to a matter as to which
notice of  default  has been  given  hereunder  and which has not been  remedied
within the time limited in this Lease.

                                      -30-

                  (B)  That  said  extension  shall  be  upon  the  same  terms,
covenants and conditions as in this lease provided,  except that (a) there shall
be no further  privilege or extension  for the term of this Lease beyond the one
period referred to above;  (b) during the said extension period the basic annual
rent shall be ninety (90%)  percent of the then market  rental being  charged by
Landlord for  comparable  space in the  Building,  but in no event less than the
Rent, plus escalations paid by Tenant in the last year of the term.

                  (C) Notwithstanding  anything in this paragraph "42" contained
to the  contrary,  the Tenant shall not be entitled to said  extension if at the
time of the  commencement  of the extended period the Tenant shall be in default
under any of the  material  terms,  covenants or  conditions  of this Lease with
respect to a matter as to which notice of default has been  hereunder  and which
has not been  remedied  within the time limited in this Lease,  or if this Lease
shall have terminated prior to the commencement of said period.

                  (D) The Tenant shall  exercise its rights to said extension of
the term of this Lease by notifying  the  Landlord of the  Tenant's  election to
exercise such right at least nine (9) months prior to the expiration of the term
of this Lease.  Upon the giving of any such  notice,  this Lease shall be deemed
extended for the specified  period,  subject to the provisions of this paragraph
"42" without execution of any further instrument.

                  (E) This option is personal to the Tenant  named  herein only.
In the event of an  assignment  of the lease to the Premises by the Tenant named
herein, this option shall be null and void and have no force and effect.

                  (F) This option shall be null and void in the event the option
for Additional Space or Second Additional Space, as Article "43" and "44".

                                ADDITIONAL SPACE

         43. A. After  January 1, 1996,  if the Lease shall be in full force and
effect and tenant shall not be in default beyond the applicable cure period,  in
the payment of Rent, Additional Rent or any other sums or charges provided to be
paid by  Tenant  under  this  Lease,  Tenant  shall  have  the  right  to  lease
approximately 12,00 square feet ("Additional Space") in place and instead of the
Premises under this Lease for a term to commence on "Substantial  Completion" of
the Additional  Space, and expire on the last day of the month which is ten (10)
years after  Substantial  Completion of the Additional  Space,  unless such term
shall  sooner  cease and  expire  pursuant  to any of the  terms,  covenants  or
conditions of this Lease or pursuant to law. Subject to the foregoing, the exact
location  and exact  size of the  Additional  Space  shall be at  Landlord  sole
discretion.  Such right to lease the Additional Space shall be exercised,  if at
all, by Tenant's  notice to Landlord  ("Tenant's  Notice") on or before December
31, 2001, and Tenant's  failure duly to give the Tenant's Notice shall be deemed
a waiver of such right to lease the Additional Space.

                                      -31-

         B. If  Tenant  shall  effectively  exercise  its  right  to  lease  the
Additional Space as set forth in Section A hereof,  then, effective on and after
"Substantial  Completion"  of all leasehold  improvements  within the Additional
Space, this Lease shall be amended as follows:

                  (i) the  Additional  Space shall be deemed to be the  Premises
demised under the Lease with the same force and effect as if originally  demised
under the Lease, and the terms "Premises", "premises", and "demised premises" as
used in the Lease shall be the Additional Space;

                  (ii) the Rent shall be an amount  equal to the  product of the
number of rentable square feet of Additional Space, multiplied by the per square
foot  rental  rate  being  paid  by  Tenant  to  Landlord  on  the  date  of the
Commencement  of the  Term  of the  Additional  Space;  and the  Rent  as  shall
thereafter be further subject to increase at the rate of $1.12 per year for each
year thereafter for the balance of the term; and

                  (iii)  Article (1A) shall be amended to reflect the new square
footage leased to Tenant and the Tenant's  proportionate share shall be adjusted
to the new proportion.

                  (iv)  Article 9 shall be amended to reflect  that new  parking
spaces shall be at the rate of four (4) spaces per 1,000 square feet of rentable
area of Additional Space.

         C. If  Tenant  shall  effectively  exercise  its  right  to  lease  the
Additional  Space,  as set forth in Section (A) of this  Article,  Tenant  shall
accept the  Additional  Space and  Landlord  shall  perform the work  therein in
accordance  with the  specifications  set forth in Schedule  "A".  All such work
shall be  substantially  completed  prior to the  commencement  of Rent for such
space.

         D. If Landlord is unable to give  possession of the  Additional  Space,
Landlord shall not be subject to any liability for failure to give possession on
said  date and the  validity  of the  Lease  shall  not be  impaired  under  any
circumstances, nor shall the same be construed in any wise to extend the term of
the Lease,  but the rent payable  hereunder  for the  Additional  Space shall be
abated  (provided  Tenant is not responsible for the delay) until after Landlord
shall  have  given  Tenant  written   notice  that  the   Additional   Space  is
substantially ready for Tenant's occupancy.

         E. The  provisions  of this  Article  are  intended to  constitute  "an
express  provision to the  contrary"  within the meaning of Section 223-a of the
New York Real Property Law.

         F. In the event  Tenant  exercises  its option  for  Second  Additional
Space,  pursuant to Article "44" of this Lease,  the  provisions of this Article
"43" shall be null and void.

                                      -32-

                             SECOND ADDITIONAL SPACE

     44. A.  Provided  the Lease  shall be in full  force and  effect and Tenant
shall not be in default beyond the applicable cure period in the payment of Rent
or Additional  Rent, or any other sums or charges  provided to be paid by Tenant
under this Lease  after  January 1, 1997,  Tenant  shall have the right to lease
approximately  24,000  square  feet  ("Second  Additional  Space")  in place and
instead of the Premises under this Lease for a term to commence on  "Substantial
Completion"  and  expire  on the last day of the month  which is ten (10)  years
after completion of the Second Additional  Space,  unless such term shall sooner
cease and expire  pursuant to any of the terms,  covenants or conditions of this
Lease or  pursuant  to law.  The exact  location  and exact  size of the  Second
Additional Space shall be at Landlord's sole discretion. Such right to lease the
Additional  Space shall be exercised,  if at all, by Tenant's notice to Landlord
("Tenant's Notice") prior to December 31, 2001 and Tenant's failure duly to give
the  Tenant's  Notice shall be deemed a waiver of such right to lease the Second
Additional Space.

     B. If Tenant  shall  effectively  exercise  its  right to lease the  Second
Additional Space as set forth in Section A hereof,  then, effective on and after
"Substantial  Completion"  of all leasehold  improvements  within the Additional
Space, this Lease shall be amended as follows:

       (i) the  Second  Additional  Space  shall be  deemed  to be the  Premises
   demised  under the Lease  with the same  force  and  effect as if  originally
   demised under the Lease, and the terms  "Premises",  "premises",  and demised
   premises" as used in the Lease shall be the Second Additional Space;

       (ii) the Rent  shall be an amount  equal to the  product of the number of
   rentable  square feet of Second  Additional  Space,  multiplied by the square
   foot  rental  rate  being  paid by  Tenant  to  Landlord  on the  date of the
   Commencement of the Term of the Second Additional Space and the Rent as shall
   thereafter  be further  subject to increase at the rate of $1.12 per year for
   each year thereafter for the balance of the term.

       (iii)  Article  (1A) shall be amended to reflect  the new square  footage
   leased to Tenant and the  Tenant's  proportionate  share shall be adjusted to
   the new proportion.

       (iv) Article 9 shall be amended to reflect that new parking  spaces shall
   be at the rate of four (4) spaces per 1,000  square feet of rentable  area of
   Second Additional Space.

     C. If Tenant  shall  effectively  exercise  its  right to lease the  Second
Additional  Space,  as set forth in Section (A) of this  Article,  Tenant  shall
accept the Second  Additional  Space and Landlord shall perform the work therein
in accordance with the  specifications  set forth in Schedule "A". All such work
shall be  substantially  completed  prior to the  commencement  of Rent for such
space.

     D. If Landlord is unable to give possession of the Second Additional Space,
Landlord shall not be subject to any liability for failure to give possession on
said  date and the  validity  of the  Lease  shall  not be  impaired  under  any
circumstances, nor shall the same be construed in any wise to extend the term of
the Lease, but the rent payable  hereunder for the Second Additional Space shall
be  abated  (provided  Tenant is not  responsible  for the  inability  to obtain
possession  or  complete  construction)  until after  Landlord  shall have given
Tenant written notice that the Second  Additional Space is  substantially  ready
for Tenant's occupancy.

     E. The  provisions of this Article are intended to  constitute  "an express
provision to the  contrary"  within the meaning of Section 223-a of the New York
Real Property Law.

     F. In the event Tenant exercises its option for Additional Space,  pursuant
to Article "43" of this Lease, the provisions of this Article "44" shall be null
and void.

                             THIRD ADDITIONAL SPACE

     45. A.  Provided  the Lease  shall be in full  force and  effect and Tenant
shall not be in default beyond the applicable cure period in the payment of Rent
or Additional  Rent, or any other sums or charges  provided to be paid by Tenant
under this Lease after  February 1, 1992,  Tenant  shall have the right to lease
approximately  5,017  square  feet  ("Third  Additional  Space")  for a term  to
commence  on  "Substantial  Completion"  and expire on the last day of the month
which is ten (10) years after completion of the Third Additional  Space,  unless
such term shall sooner cease and expire pursuant to any of the terms,  covenants
or  conditions  of this Lease or pursuant to law.  The exact  location and exact
size of the Third  Additional  Space shall be adjacent.  Such right to lease the
Additional  Space shall be exercised,  if at all, by Tenant's notice to Landlord
("Tenant's  Notice") prior to February 1, 1992 and Tenant's failure duly to give
the  Tenant's  Notice  shall be deemed a waiver of such right to lease the Third
Additional Space.

     B. If  Tenant  shall  effectively  exercise  its  right to lease  the Third
Additional Space as set forth in Section A hereof,  then, effective on and after
"Substantial  Completion"  of all leasehold  improvements  within the Additional
Space, this Lease shall be amended as follows:

       (i) the Third Additional Space shall be deemed to be the Premises demised
   under the Lease with the same force and effect as if originally demised under
   the Lease, and the terms  "Premises",  "premises",  and demised  premises" as
   used in the Lease shall be the Third Additional Space;

       (ii) the Rent  shall be an amount  equal to the  product of the number of
   rentable square feet of Third Additional Space, multiplied by the


                                      -34-


   square  foot  rental rate being paid by Tenant to Landlord on the date of the
   Commencement of the Term of the Third  Additional Space and the Rent as shall
   thereafter  be further  subject to increase at the rate of $1.12 per year for
   each year thereafter for the balance of the term.

       (iii)  Article  (1A) shall be amended to reflect  the new square  footage
   leased to Tenant and the  Tenant's  proportionate  share shall be adjusted to
   the new proportion.

       (iv) Article 9 shall be amended to reflect that new parking  spaces shall
   be at the rate of four (4) spaces per 1,000  square feet of rentable  area of
   Third Additional Space.

     C. If  Tenant  shall  effectively  exercise  its  right to lease  the Third
Additional  Space,  as set forth in Section (A) of this  Article,  Tenant  shall
accept the Third Additional Space and Landlord shall perform the work therein in
accordance  with the  specifications  set forth in Schedule  "A".  All such work
shall be  substantially  completed  prior to the  commencement  of Rent for such
space.

     D. If Landlord is unable to give possession of the Third Additional  Space,
Landlord shall not be subject to any liability for failure to give possession on
said  date and the  validity  of the  Lease  shall  not be  impaired  under  any
circumstances, nor shall the same be construed in any wise to extend the term of
the Lease,  but the rent payable  hereunder for the Third Additional Space shall
be  abated  (provided  Tenant is not  responsible  for the  inability  to obtain
possession  or  complete  construction)  until after  Landlord  shall have given
Tenant written notice that the Third Additional Space is substantially ready for
Tenant's occupancy.

     E. The  provisions of this Article are intended to  constitute  "an express
provision to the  contrary"  within the meaning of Section 223-a of the New York
Real Property Law.

     IN WITNESS WHEREOF, Landlord and Tenant have respectively signed and


                                      -35-

                                  SCHEDULE "C"

     1.  Landlord  shall provide at the rates  hereinafter  set forth and Tenant
shall purchase from Landlord "energy service" for Tenant's  requirements.  There
shall be the following categories of energy service:

     A) NORMAL  SERVICE:  NORMAL SERVICE is energy consumed during Working Hours
as defined in Article 6 whose power  demands do not exceed 4 watts per  rentable
square foot of the Demised Premises,  or part thereof, per Working Hour. Of this
amount,  two watts are allocated to Landlord  supplied  lighting.  Two watts are
allocated for Tenant's usual office equipment ("TENANT'S ALLOWABLE USE").

     B) EXCESS SERVICE: EXCESS SERVICE is energy demanded,  regardless of hours,
in excess of ALLOWABLE USE.

     C) OVERTIME SERVICE; OVERTIME SERVICE is energy consumed at all other hours
than WORKING HOURS ("OVERTIME HOURS").  For the purpose of OVERTIME SERVICE, the
Demised Premises may be separated into zones of use. The minimum  practical size
of these  zones is 2500  square  feet.  Zones less than 2500 square feet will be
billed at the rate applicable to 2500 square feet.

                                      -40-

     2. Charges for NORMAL SERVICE:  The charge for NORMAL SERVICE is payable at
the rate of $2.25 per annum per rentable square foot of the Demised Premises and
is subject to escalation as hereinafter provided. The charged for NORMAL SERVICE
is included in the monthly rent set forth in Article 3. Any escalation  shall be
payable as additional  rent.  After this, the charge to change  "WORKING  HOURS"
shall be $25.00 per zone.

     3. Charges for  OVERTIME  SERVICE:  Subject to  escalation  as  hereinafter
provided the Landlord's monthly charge for Tenant's OVERTIME SERVICE, payable in
addition  to any  additional  charges for NORMAL  SERVICE and EXCESS  SERVICE if
applicable, shall be derived as follows:

     A) Full Energy OVERTIME SERVICE:  An amount equal to the number of OVERTIME
HOURS in the month,  multiplied  by  rentable  square  feet of the zones in use,
multiplied by $.0022.

     B) OVERTIME  charges shall be increased by the same  percentage  the EXCESS
SERVICE (if applicable) exceeds the ALLOWABLE USE for NORMAL SERVICE.

     C)  Equipment  Energy:  Any energy use in the  Tenant's  space,  outside of
NORMAL SERVICE and OVERTIME  SERVICE,  shall be charged an amount equal to $1.28
per year,  multiplied by the  connected  watts (or part  thereof),  computed and
adjusted to the nearest 100th).

     These amounts shall be billed at least once every three months and shall be
payable during the month in which billed as additional rent

     4. Charges for EXCESS SERVICE:  The Landlord's monthly charges for Tenant's
EXCESS  SERVICE  payable in  addition  to any  charges  for NORMAL  SERVICE  and
OVERTIME  SERVICE,  if applicable,  shall be an amount  derived as follows:  The
excess above the TENANT'S  ALLOWABLE  USE shall be charged to tenant at the rate
of $0.625 per  square  foot per year,  for each  excess  watt (or part  thereof,
computed and adjusted to the nearest 100th).

                                      -41-

     5.  Escalation of Charges for NORMAL  SERVICE,  EXCESS SERVICE AND OVERTIME
SERVICE AND TWENTY-FOUR HOUR SERVICE: The rates referred to in this Schedule "C"
are based upon current rates promulgated by the utility company during the month
prior to the  "Commencement  Date." All of the rates, fuel and adjustment costs,
state and local  government  taxes, and all other component parts of the utility
company  charges  referred  to in this  Schedule  "C" are subject to increase to
reflect changes in rate or  classification  or other component parts of the bill
employed by the utility  company  providing  services  to the  building.  Tenant
agrees to pay such increase in utility company charges.  Landlord shall give due
notice to Tenant of any such  increase or change in charge.  Tenant shall not be
or  become  entitled  to a  reduction  in  rent,  additional  rent  or to  other
reimbursement  in the  event  it uses  less  energy  than  contemplated  by this
Schedule "C".

     6. Landlord's energy  management system will be conclusive  evidence of the
computation of Normal Service, Excess Service,  Overtime Service and Twenty-four
Hour Service.  However,  Landlord hereby reserves to itself the right, from time
to time, to cause a reputable electric  engineering  company (the "Engineer") to
make a survey of Tenant's  energy usage  requirements  to determine  whether the
Tenant's  Allowable Use limitation has been exceeded and, if so, to what extent.
If these  surveys  indicate  at the time  that the cost to  Landlord  by  reason
thereof, computed on an annual basis at rates which would be charged by a public
utility  company  servicing the Building for such purposes,  is in excess of the
initial cost similarly  computed,  then the additional rent provided for in this
Schedule  shall be increased as provided for herein,  commencing  with the first
day of the month  immediately  following the  computation of such survey and the
submission of a copy thereof to Tenant.

     7. Landlord shall have full and unrestricted access to all air-conditioning
and heating  equipment,  and to all other  utility  installations  servicing the
Building and the Demised  Premises.  Landlord  reserves the right temporarily to
interrupt,  curtail,  stop or suspend  air-conditioning and heating service, and
all other utility, or other services, because of Landlord's inability to obtain,
or difficulty or delay in obtaining,  labor or materials necessary therefor,  or
in order to comply with governmental  restrictions in connection  therewith,  or
for any other cause beyond  Landlord's  reasonable  control.  No  diminution  or
abatement of Basic Rent, Additional Rent, or other compensation shall or will be
claimed by Tenant,  nor shall  this  Lease or any of the  obligations  of Tenant
hereunder be affected or reduced by reason of such  interruptions,  stoppages or
curtailments,  the causes of which are herein  above  enumerated,  nor shall the
same give rise to a claim in Tenant's favor that such failure constitutes actual
or  constructive,  total or partial eviction from the Demised  Premises,  unless
such  interruptions,  stoppages or curtailments  have been due to the arbitrary,
willful or negligent act, or failure to act, of Landlord.

     8.  Telephone and service  shall be the  responsibility  of Tenant.  Tenant
shall make all  arrangements  for telephone  service with the company  supplying

                                      -42-

said service,  including the deposit  requirement for the furnishing of service.
Landlord  shall not be responsible  for any delays  occasioned by failure of the
telephone company to furnish service.
