may  perform  Tests  and  Studies  and  may  inspect  the  physical   (including
environmental)  and  financial  condition  of the  Premises,  including  but not

this  Agreement,  Purchaser  shall be entitled to the return of the Deposit with
interest  earned  thereon,  and  this  Agreement  shall be null and void and the

notification  of its  intention  to conduct  any such  inspection  and that such
inspection  shall  not  unreasonably   impede  the  normal  day-to-day  business
operation of the  Premises.  Such right of  inspection  and the exercise of such
right  shall  not  constitute  a  waiver  by  Purchaser  of  the  breach  of any
representation  or warranty of Seller  which might have been  disclosed  by such
inspection.

                  Seller agrees to permit  Purchaser access to the Premises upon
prior notice to Seller for the purpose of performing  the Tests and Studies.  To
assist  Purchaser  in the  performance  of its Tests  and  Studies,  Seller  has

environmental   reports  (including,   without  limitation,   all  Environmental
Documents),  surveys, title materials and engineering and architectural data and
the like relating to the Premises  that are in Seller's  possession or under its

Purchaser.  In the event any  additional  materials or  information  come within

necessary in order for Purchaser to perform the same. Purchaser shall repair and

substantially the same condition as existed prior to such disturbance.

Payment") by a bank,  certified or cashier's check on the Closing Date or by the

         5.       MATTERS TO WHICH THIS SALE IS SUBJECT

                  The  Premises  are sold and are to be conveyed  subject to the
following (collectively the "Permitted Encumbrances"):

                  (a) The liens of real estate taxes,  personal  property taxes,
water charges, and sewer charges provided same are not due and payable;

                  (b) The rights of the Tenant, as tenant only;

                  (c)  Those  restrictions,  covenants,  agreements,  easements,
matters  and  things  affecting  title to the  Premises  and  more  particularly
described  in  Exhibit  "D"  annexed  hereto and by this  reference  made a part
hereof;

                  (d) Any and all  laws,  statutes,  ordinances,  codes,  rules,
regulations,  requirements,  or  executive  mandates  as the same may be amended
subsequent  to the date  hereof  affecting  the  Premises  adopted by the United
States, the State of New Jersey, the Township of Basking Ridge and any and every
other Governmental Authority having jurisdiction thereof;

                  (e) The state of facts shown on that certain  survey  prepared
by Couvrette  Associates  Inc.  and dated August 8, 1988 and revised  August 25,
1988 and any other  state of facts  which a recent  and  accurate  survey of the
Premises  would  actually  show,  provided  same  do not  impair  the use of the
Premises as an office  building and do not render title  uninsurable at standard
rates; and

                  (f) Those Service Contracts which are assumed by Purchaser, at
its option, at Closing.

         6.       ADJUSTMENTS

                  (a) The following items with respect to the Premises are to be
apportioned as of midnight on the date preceding the Closing:

                           (i)  Rents   payable   by  the  Tenant  as  and  when
collected.  All monies received from the Tenant from and after the Closing shall
belong to Purchaser and shall be applied by Purchaser to current rents and other
charges due under the Lease.  After  application of such monies to current rents
and charges,  Purchaser agrees to remit to Seller any excess amounts paid by the
Tenant to the extent that the Tenant was in arrears in the payment of rent prior
to the Closing,  not in excess of one (1) month's rent.  The  provisions of this
subsection 6(a) shall survive the Closing Date.

                           (ii) Amounts payable under the Service Contracts,  to
the extent Purchaser assumes such Service Contracts at Closing.

                           (iii)  Real  estate  taxes due and  payable  over the
calendar year. If the Closing Date shall occur before the tax rate is fixed, the
apportionment  of real estate  taxes shall be upon the basis of the tax rate for
the preceding year applied to the latest  assessed  valuation.  If subsequent to
the Closing Date, real estate taxes (by reason of change in either assessment or
rate or for any other reason) for the Premises should be determined to be higher
or lower than those that are apportioned,  a new computation  shall be made, and
Seller agrees to pay Purchaser any increase shown by such recomputation and vice
versa. The provisions of this Subsection 6(a)(v) shall survive the Closing Date.

                  (b)  Except  as  otherwise  provided  in this  Agreement,  the
adjustments  shall be made in  accordance  with the  customs in respect to title
closings in the State of New Jersey.

                  (c)  Any  errors  in  calculations  or  adjustments  shall  be
corrected or adjusted as soon as practicable after the Closing.


         7.       ESTOPPEL CERTIFICATE

                  (a)  Promptly  following  delivery by Purchaser to Seller of a
notice that it is not terminating this Agreement as it is otherwise permitted so
to do  pursuant  to Section 3,  Seller  shall  deliver to the Tenant an estoppel
certificate  in the form annexed  hereto as Exhibit "E" for Tenant's  execution,
completed  to reflect  the  Tenant's  particular  Lease  status  (the  "Estoppel
Certificate").  Seller  agrees to use its best  efforts to obtain  the  Estoppel
Certificate  within  the  thirty  (30) day period set forth in the Lease for the
Tenant to respond to a request for delivery of an estoppel  certificate.  Seller
shall be entitled to extend the Closing Date, by written notice to Purchaser, to
obtain the  Estoppel  Certificate  if same is not obtained by the date first set
forth in this Agreement for the Closing; provided,  however, Seller shall not be
entitled to extend the Closing past the outside date for Tenant to so respond to
Seller's request.

                  (b)  As a  condition  to  Closing,  Seller  shall  deliver  to
Purchaser  the  Estoppel  Certificate,  or  in  the  alternative,  the  estoppel
certificate required under the Lease, in either event executed by the Tenant and
describing  no  adverse  conditions  or  information  which  renders  untrue  or
incorrect any representation or warranty made by Seller herein.

Policy  shall  contain   endorsements   insuring  that  (i)  the  covenants  and

standard  printed  policy and survey  exceptions.  Seller  shall be obligated to
expend up to the Purchase Price to cause title to the Premises to be conveyed to
Purchaser in the manner required under this Agreement.

                  (b)  If,  at the  Closing,  Seller  is  unable  to  convey  to
Purchaser  insurable title to the Premises subject to and in accordance with the
provisions  of this  Agreement,  Seller shall be entitled,  upon written  notice
delivered to Purchaser at or prior to the Closing, to reasonable adjournments of
the Closing  Date one or more times,  for a period or periods not to exceed,  in
the  aggregate,  thirty (30) days,  to enable  Seller to convey such title or to
fulfill such obligations. If Seller does not so elect to adjourn the Closing, or
if at the  adjourned  date  Seller is still  unable to  convey  insurable  title
subject to, and in  accordance  with the  provisions  of, this  Agreement,  then
Purchaser  may, at its option,  (a) terminate  this  Agreement by written notice
delivered as provided in Section 23 hereof, in which event the sole liability of
Seller shall be to direct the Title  Company to refund the Deposit with interest
thereon  to  Purchaser,  and to refund to  Purchaser  all  charges  made for (i)
examining the title, (ii) any appropriate  additional municipal searches made in
accordance with this Agreement,  and (iii) survey and survey inspection charges;
or (b) accept title to the Premises  subject to such  defect(s),  in which event
such defect(s)  shall become  Permitted  Encumbrance(s).  Upon such refund being
made to Purchaser in  accordance  with clause (a) of the  immediately  preceding
sentence,  then this Agreement shall automatically become void and of no further
force or effect,  and neither party shall have any  obligations of any nature to
the other hereunder or by reason hereof,  except obligations which,  pursuant to
the  provisions  of  this  Agreement,   are  expressly  stated  to  survive  the
termination  of this  Agreement.  If Seller  elects to  adjourn  the  Closing as
provided above,  this Agreement shall remain in effect for the period or periods
of adjournments, in accordance with its terms.

                  (c) Upon notice to Seller,  Purchaser  shall have the right to
cause one or more title  insurance  companies,  whether or not through  abstract
agencies, to insure Purchaser's title to the Premises on a co-insurance basis or
to change title companies, so long as in each instance, said company and agency,
to the extent applicable,  is a duly licensed title insurance company authorized
to conduct business in the State of New Jersey.


         18.      CASUALTY LOSS

                  (a) If prior to the Closing  Date any part of the  Premises is
damaged as the result of fire or other casualty and the estimated cost of repair
of the damage exceeds $50,000.00,  Purchaser shall have the option to either (i)
accept  title to the  Premises  without  any  abatement  of the  Purchase  Price
whatsoever,  in which event on the Closing  Date all of the  insurance  proceeds
shall be assigned by Seller to Purchaser and any moneys theretofore  received by
Seller in  connection  with such  fire or other  casualty  shall be paid over to
Purchaser,  or (ii) cancel this  Agreement  and the  Deposit  together  with all
interest earned thereon shall be returned to Purchaser by the Escrow Agent,  and
upon such return neither party shall have any further liability or obligation to
the other.  In the event that the  damages  shall not  exceed  $50,000.00,  this
Agreement shall remain in full force and effect, the insurance proceeds shall be
assigned by Seller to Purchaser  and all sums  received by Seller in  connection
therewith shall be paid over to Purchaser.  Seller shall maintain or cause to be
maintained insurance on the Premises in accordance with the terms and conditions
of the Lease.

                  (b) Seller  shall not settle any fire or casualty  loss claims
in connection  with the Premises  without  obtaining  Purchaser's  prior written
consent.

                  (c) Seller  hereby  agrees to furnish  Purchaser  with written
notification of any such fire or casualty within  twenty-four (24) hours of such
event.


         19.      CONDEMNATION

                  In the event of the institution of any proceedings,  judicial,
administrative or otherwise,  which shall relate to the proposed material taking
of any portion of the Premises by eminent  domain prior to the Closing  Date, or
in the event of the  material  taking of any portion of the  Premises by eminent
domain prior to the Closing Date,  Purchaser  shall have the right and option to
terminate  this  Agreement by giving the Seller written notice to such effect at
any time after its receipt of written  notification of any such occurrence.  Any
damage to or  destruction  of the  Premises  as a result of a taking by  eminent
domain  shall be  deemed  "material"  for  purposes  of this  Section  19 if the
estimate  of the damage,  which  estimate  shall be  performed  by an  insurance
adjustor and Purchaser's architect, shall exceed $50,000.00. Should Purchaser so
terminate  this  Agreement  in  accordance  with this  Section  19, the  Deposit
together with interest earned thereon shall immediately be returned to Purchaser
by the Escrow Agent and upon such return,  neither  party shall have any further
liability or obligations to the other. In the event Purchaser shall not elect to
cancel  this  Agreement,  Seller  shall  assign all  proceeds  of such taking to
Purchaser, and same shall be Purchaser's sole property, and Purchaser shall have
the sole right to settle any claim in connection with the Premises.


         20.      REMEDIES

                  (a) In the event  Purchaser  fails to perform  on the  Closing
Date,  Purchaser's sole liability and Seller's sole recourse shall be limited to
the  amount  of the  Deposit.  Seller  agrees  that  retention  of  the  Deposit
constitutes fixed and liquidated damages resulting from Purchaser's default, and
Seller waives any other claim, at law or in equity,  either against Purchaser or
against any person, known or unknown, disclosed or undisclosed.

                  (b) (i) If, after  complying with the terms of this Agreement,
Seller  shall be unable to convey the Premises in  accordance  with the terms of
this  Agreement,  the sole obligation and liability of Seller shall be to direct
the Escrow Agent to refund to Purchaser the Deposit,  and to pay Purchaser's net
cost of examining  title,  which cost is not to exceed the charges  fixed by the
local board of title  underwriters  and  actually to be paid by  Purchaser,  and
survey  charges  actually  to be paid by  Purchaser,  which  charges  for  title
examination and survey are not to exceed $5,000,  whereupon this Agreement shall
be deemed  cancelled and the parties hereto shall be released of all obligations
and liabilities under this Agreement,  except those that are expressly stated to
survive the cancellation or termination of this Agreement.

                           (ii)  In the  event  of any  default  on the  part of
Seller or  Seller's  failure  to comply  with any  representation,  warranty  or
agreement in any material respect, Purchaser shall be entitled to terminate this
Agreement upon notice to Seller, in which event the Deposit shall be returned by
Escrow Agent to Purchaser  and neither party shall  thereafter  have any further
obligations  under this Agreement;  to commence an action against Seller seeking
specific performance of Seller's obligations under this Agreement; to pursue all
of its remedies at law or in equity; or to do any or all of the above.

                  (c) The acceptance of the Deed by Purchaser  shall be deemed a
full performance and discharge of every agreement and obligation of Seller to be
performed  under this Agreement,  except those,  if any, which are  specifically
stated in this Agreement to survive the Closing.


         21.      ASSESSMENT

                  If, on the Closing  Date,  the  Premises  or any part  thereof
shall be or shall have been affected by an assessment or  assessments  which are
or may become payable in annual installments,  of which the first installment is
either  then a charge or lien or has been paid,  then for the  purposes  of this
Agreement all the unpaid  installments of any such  assessment,  including those
which are to become due and payable after the Closing  Date,  shall be deemed to
be due and  payable  and to be liens  upon the  Premises  and  shall be paid and
discharged by Seller on the Closing Date.


         22.      CLOSING

                  The closing and  delivery  of the Deed (the  "Closing")  shall
take place at the offices of Pryor,  Cashman,  Sherman & Flynn, 410 Park Avenue,
New York,  New York 10022 on or about the Closing Date, but subject to extension
by Seller as provided in Section 7. Upon notice to Seller,  Purchaser  may elect
to  accelerate  the Closing Date to a date not less than five (5) days after the
date of Purchaser's notice.


         23.      NOTICE

                  All  notices,  demands,  requests,  or other  writings in this
Agreement provided to be given or made or sent, or which may be given or made or

         24.      ESCROW AGREEMENT

                  Upon the signing of this  Agreement by the parties,  Purchaser
shall  deliver  the  Deposit to the Escrow  Agent.  The  parties  agree that the
Deposit  shall be held by the  Escrow  Agent in escrow and  disposed  of only in
accordance with the provisions of this Section 24. The parties agree that if the
Deposit is cash,  such cash shall be invested in an assignable  interest-bearing
certificate  of deposit,  money  market  fund,  treasury  bill or other  similar
security  approved by Seller and Purchaser,  and all interest  accruing  thereon
shall be paid to Purchaser, except as otherwise provided herein.

                  (a) The Escrow  Agent will deliver the Deposit to Seller or to
Purchaser, as the case may be, under the following conditions:

                           (i) To Seller on the Closing Date;

                           (ii)  To  Seller  upon  receipt  of  written   demand
therefor, such demand stating that Purchaser has defaulted in the performance of
this  Agreement  and  specifically  setting  forth the  facts and  circumstances
underlying such default. The Escrow Agent shall not honor such demand until more
than five (5) days have elapsed after the Escrow Agent has mailed a copy of such
demand to Seller or Purchaser,  as the case may be, nor thereafter if the Escrow
Agent  shall  have  received  written  notice of  objection  from  Purchaser  in
accordance with the provisions of clause (b) of this Section 24; or

                           (iii) To  Purchaser  upon  receipt of written  demand
therefor,  such  demand  stating  that this  Agreement  has been  terminated  in
accordance  with  the  provisions   hereof,  or  Seller  has  defaulted  in  the
performance  of this  Agreement,  and  specifically  setting forth the facts and
circumstances  underlying the same. The Escrow Agent shall not honor such demand
until more than five (5) days have  elapsed  after the Escrow Agent has mailed a
copy of such demand to Seller or Purchaser,  as the case may be, nor thereafter,
if the Escrow Agent shall have  received  written  notice of objection  from the
other party in accordance with the provisions of clause (b) of this Section 24.

                  (b) Upon the  filing of a written  demand  for the  Deposit by
Purchaser or Seller,  pursuant to subclause  (ii) or (iii) of clause (a) of this
Section 24, the Escrow  Agent shall  promptly  mail a copy  thereof to the other
party.  The other  party  shall have the right to object to the  delivery of the
Deposit by filing  written notice of such objection with the Escrow Agent at any
time  within  five  (5) days  after  the  mailing  of such  copy to it,  but not
thereafter.  Such notice shall set forth the basis for objecting to the delivery
of the Deposit.  Upon receipt of such  notice,  the Escrow Agent shall  promptly
mail a copy thereof to the party who filed the written demand.

                  (c) In the event the  Escrow  Agent  shall have  received  the
notice of objection provided for in clause (b) above and within the time therein
prescribed,  the Escrow Agent shall  continue to hold the Deposit  until (i) the
Escrow Agent  receives  written  notice from Seller and Purchaser  directing the
disbursement  of said  Deposit,  in which  case,  the  Escrow  Agent  shall then
disburse said Deposit in accordance with said direction, or (ii) in the event of
litigation  between  Seller and  Purchaser,  the Escrow Agent shall  deliver the
Deposit to the Clerk of the Court in which said litigation is pending,  or (iii)
the Escrow  Agent takes such  affirmative  steps as the Escrow Agent may, in the
Escrow  Agent's  reasonable  opinion,  elect in order to  terminate  the  Escrow
Agent's duties  including,  but not limited to,  depositing the Deposit with the
Court and bringing an action for interpleader,  the costs thereof to be borne by
whichever of Seller or Purchaser is the losing party.

                  (d) The  Escrow  Agent  may act upon any  instrument  or other
writing  believed  by it in  good  faith  to be  genuine  and to be  signed  and
presented by the proper person and it shall not be liable in connection with the
performance  of any duties  imposed upon the Escrow Agent by the  provisions  of
this Agreement, except for damage caused by the Escrow Agent's own negligence or
willful  default.  The Escrow  Agent  shall  have no duties or  responsibilities
except  those set  forth  herein.  The  Escrow  Agent  shall not be bound by any
modification  of this  Agreement,  unless the same is in  writing  and signed by
Purchaser and Seller,  and, if the Escrow Agent's duties hereunder are affected,
unless the Escrow Agent shall have given prior written consent  thereto.  In the
event that the Escrow Agent shall be uncertain as to the Escrow  Agent's  duties
or rights  hereunder,  or shall receive  instructions  from  Purchaser or Seller
which, in the Escrow Agent's opinion, are in conflict with any of the provisions
hereof,  the  Escrow  Agent  shall be  entitled  to hold and apply  the  Deposit
pursuant  to clause  (c) above and may  decline  to take any other  action.  The
Escrow Agent shall not charge a fee for its services as escrow agent.


         25.      ASSIGNMENT.

                  Purchaser shall have the right, at its sole option,  to assign
its rights hereunder to an affiliate of Purchaser upon written notice to Seller.


         26.      ENVIRONMENTAL REPRESENTATIONS AND WARRANTIES;
                  COVENANTS; CONDITIONS.

         A. Seller  represents  and  warrants  that to its  knowledge  after due

portion of the Premises has ever been used by Seller, or any current occupant or
operator,  or any former owner,  occupant or operator to generate,  manufacture,
refine,  produce,  treat,  store,  handle,  dispose  of,  transfer,  process  or
transport Hazardous Materials,  whether or not any of those parties has received
notice or advice from any  Governmental  Authority  or other source with respect
thereto;  (d) no  portion  of the  Premises  is now,  or has ever been used as a
"Major  Facility,"  and  Seller has not used,  and does not  intend to use,  any

whatsoever  with  respect  to  Hazardous  Materials  on, at,  emanating  from or
affecting the Premises, Seller shall immediately notify Purchaser.

         B. Seller  represents  and  warrants  that to its  knowledge  after due
inquiry,  no lien has been attached to the Premises as a result of any action by
the  Commissioner of the NJDEP or its successor or its designee  pursuant to the
New  Jersey  Spill  Compensation  Fund as such term is  defined in the Spill Act
expending  monies  from  said fund to pay for  "cleanup  and  removal  costs" or
"natural  resources"  damages as a result of any  "discharge"  of any "hazardous
substances"  on or at the Premises,  as such terms are defined in the Spill Act.
Seller further represents, warrants, covenants and agrees that Seller has not in

not satisfied on or before the ISRA  Compliance  Date,  Purchaser shall have the
right to extend the ISRA  Compliance  Date or to terminate  this  Agreement,  in

the date of this Agreement,  and subsequently promptly upon receipt by Seller or
Seller's  representatives,  Seller shall deliver to Purchaser the following,  to
the extent not previously  delivered and within Seller"s  possession or control:
(i) all  Environmental  Documents  concerning  or  generated  by or on behalf of
predecessors in title or former occupants of the Premises  whether  currently or
hereafter existing;  (ii) all Environmental Documents concerning or generated by
or on behalf of Seller,  whether  currently  or  hereafter  existing;  (iii) all
Environmental  Documents  concerning  or generated by or on behalf of current or
future occupants of the Premises,  whether currently or hereafter existing;  and

         F. Seller shall notify  Purchaser in advance of all meetings  scheduled
between  Seller  or  Seller's  representatives  and  NJDEP  and  Purchaser,  and
Purchaser's  representatives shall have the right, without obligation, to attend
and participate in all such meetings.

         G. Seller shall indemnify,  defend and hold harmless Purchaser from and
against all claims, liabilities,  losses, damages, penalties and costs, foreseen
or unforeseen including, without limitation, counsel, engineering,  attorney and

Seller's obligation under this Section 26.

         H.  Seller  further  represents  and  warrants  the  following  to  its
knowledge, after due inquiry:

Seller issued pursuant to CERCLA.

                  (ii)  Seller has not  received a written  notice of  intention
concerning   the  Premises  to  commence   suit   pursuant  to  the  New  Jersey
Environmental  Rights Act,  N.J.S.A.  2A:35A-1 et seq.,  and, to its  knowledge,
