Item 2.  Acquisition or Disposition of Assets

Pursuant  to a Purchase and Sale Agreement dated as
of  April
4, 2000, as amended (the "Agreement"), Taxter
Park Associates ("TPA")  sold  the land and
buildings which  comprise  Taxter Corporate  Park
(the  "Property")  on  May  23,  2000  to  a
subsidiary of Mack-Cali Realty Corporation (the
"Purchaser"), an unaffiliated party, for a
negotiated sale price of $42.725 million.  In
connection with the sale, TPA acquired  from  DW
Taxter  Special  Corp., an affiliate,  and
conveyed  to  the Purchaser   certain  interests
in  the  Property,  including interests  that
the affiliate had acquired  from  KLM  Royal
Dutch  Airlines, for $6.75 million, in February
1999. Of  the $42.725  million,  TPA will remit
$6.75 million of  the  sale proceeds to the
affiliate in connection with the transaction.

TPA  is  owned 14.8% by Dean Witter Realty Income
Partnership II,  L.P.  (the  "Partnership"),
40.6% by Dean Witter  Realty
Income   Partnership   IV,   L.P.,   an   affiliated
public partnership,   and  44.6%  by  Dean  Witter
Realty   Income Partnership III, L.P., an affiliated
public partnership.
The  purchase price was paid in cash at closing.  At
closing, the   Partnership   received   approximately
$4.9   million representing its 14.8% share of the cash
received by TPA, net of  its  share  of  TPA's closing
costs, the  amount  of  the obligation owed to the
affiliate and other deductions.

Item 7.  Financial Statements and Exhibits

(b)  Pro Forma Financial Information

On  a  pro forma basis, if the sale of the Property had
been consummated  on  January 31, 2000, the Partnership's
Balance Sheet  as  of  such date would have reflected an
increase  in cash  and cash equivalents from $1.4 million
to $6.3 million, the  elimination  of  the $2.3 million
investment  in  joint venture,  and  an  increase in
partner's  capital  from  $3.6 million to $6.2 million.

For  the  Income Statement for the quarter ended January
31, 2000,  if  the  Property was sold on November  1,
1999,  the equity  in earnings of joint venture of
approximately $48,000 would  have  been eliminated and
the Partnership  would  have incurred  a  net  loss of
approximately  $34,000  ($0.17  per limited partnership
unit).

For the Income Statement for the year ended October 31,
1999, if  the Property was sold on November 1, 1998, the
equity  in earnings  of  joint venture of approximately
$239,000  would have  been  eliminated and  net income
would  have  decreased from approximately $4,861,000
($27.29 per limited partnership unit)   to  approximately
$4,622,000  ($26.08  per   limited
partnership unit).

The  pro  forma adjustments to the Income Statements
exclude the Partnership's share of the non-recurring gain
on the sale of the Property.

     Rent  payable  by  it for the month  in  which  the
     Closing occurs (whether or not it is in arrears for
     such month on the Closing Date), any Rents received
     by  the  Purchaser or the Seller from  such  tenant
     after  the Closing shall be applied to amounts  due
     and  payable  by such tenant during  the  following
     periods   in  the  following  order  of   priority:
     (i)  first,  to  the  month in  which  the  Closing
     occurred, (ii) second, to

     <PAGE>

     the  current month, and (iii) third, to the  months
     in  which any arrearages exist, paying off the most
     recent  arrears  first.  If Rents  or  any  portion
     thereof  received  by the Seller or  the  Purchaser
     after  the Closing are due and payable to the other
     party by reason of this allocation, the appropriate
     sum,  less  a proportionate share of any reasonable
     attorneys' fees and costs and expenses expended  in
     connection  with the collection thereof,  shall  be
     promptly paid to the other party (to the extent not
     collected  from  or  reimbursed  by  tenants).   At

     schedule of any Rents in arrears as of the  Closing

increases, utility,  sewer or water charges
or other  charges, however characterized

Rents  are collected by  the  Purchaser from
a  tenant  after the Closing Date,  then
the Purchaser  shall promptly apply such
sums  received from  such  tenant during the
following periods  in the following order of
priority:  (i) first, to the month  in which
the Closing occurred, (ii)  second, to  the
current  month, and (iii)  third,  to  the
months  in  which any arrearages exist,
paying  off the most recent arrears first.
If Additional Rents or  any  portion thereof
received by the Seller  or the Purchaser
after the Closing are due and payable to
the  other party by reason of this
allocation, the appropriate sum, less a
proportionate share  of any                     reasonable
attorneys'  fees  and  costs  and
expenses expended in connection with the
collection thereof, shall be promptly paid
to the other  party (to the extent not
collected from or reimbursed  by tenants).
At the Closing, Seller shall deliver  to
Purchaser  a  list  of Additional  Rent
billed  to tenants for the calendar  year in
which the Closing occurs  (both  on  a
monthly  basis  and  in                 the
aggregate), the basis for which the monthly
amounts are being billed and the amounts
incurred by Seller on account of the
components of Additional Rent for such
calendar  year.  Upon the  reconciliation
by Purchaser   of  the  Additional  Rents
billed                                          to
Tenants, and the amounts actually incurred
for such calendar year, Seller and Purchaser
shall be liable for overpayments of
Additional Rents, and shall  be entitled to
payments from Tenants, as the case  may be,
on a pro-rata

<PAGE>

     basis  based  upon  each  party's
period                                          of
ownership during such calendar year.  To the
extent Seller is liable for an overpayment,
it shall  make such  overpayment to
Purchaser within  thirty  (30) days  after
request, for further  distribution  by
Purchaser to the tenants, as applicable.
      3.2.3.  Collection After the Closing.

     After  the Closing, the Seller shall
continue to  have  the  right, in its own
name,  to  demand payment of and to collect
Rent and Additional  Rent arrearages owed to
the Seller by any tenant,  which right
shall include, without limitation, the right
to   continue   or   commence  legal
actions                                         or
proceedings against any tenant; provided,
however, Seller  shall be limited to a
contract  action  for recover  of monies
only, and under no circumstances shall
Seller be permitted to bring an  action  for
eviction,  ouster  or removal  of  any
tenant  the Purchaser  agrees to cooperate
with the Seller  for all reasonable respects
and at no

<PAGE>

cost  or  expense to Purchaser, in
connection  with such  efforts by the Seller
to collect  such  Rents
     and Additional Rents and to take all steps,
     whether before  or  after  the  Closing  Date,
     as  may  be reasonably necessary to carry out the
     intention  of the  foregoing, including, without
     limitation,  the delivery  to  the  Seller,  upon
     demand,  of any
     relevant books and records (including any  Rent
     or Additional  Rent  statements, receipted  bills
     and copies  of  tenant checks used in payment  of
     such Rent or Additional Rent), the execution of
     any  and all
     consents   or   other  documents,         and
     the
     undertaking of any act reasonably necessary for
     the collection  of such Rents and Additional
     Rents  by the
     Seller.   If  for  any  fiscal  period  which
     includes  the  Adjustment Date tenants  are
     paying Additional  Rent based upon estimates
     prepared  by the
     Seller,  such  Additional  Rents   shall
     be
     reapportioned  when  the actual  expenses  for
     the fiscal period are known.
     3.3.  Water.
     If  there  is  a  water meter on the Property,
the Seller  shall furnish a reading to a date not more
than thirty  (30)  days prior to the Closing  Date,
and  the unfixed  water  charges and sewer rent,  if
any,  based thereon for the intervening time shall be
apportioned on the basis of such last reading.
     3.4.  Utilities.

     The  Seller  will  use all commercially
reasonable efforts  to  obtain  final  cut-off
readings  of  fuel, telephone,  electricity, and gas
to be made  as  of  the Adjustment  Date.  The Seller
shall pay the bills  based on  such  readings promptly
after the same are rendered. If  arrangements  cannot
be made for  any  such  cut-off reading,  the  parties
shall apportion the  charges  for such services on the
basis of the bill therefor for  the most recent
billing period prior to the Adjustment Date, and  when
final bills are rendered for the period  which
includes  the  Adjustment Date the Seller and
Purchaser shall promptly readjust the apportionments
in accordance with such final bills.
     3.5.  Post-Closing Adjustments.

     The  items  set forth in this Section  3  shall
be apportioned at the Closing by payment of the net
amount of  such apportionments to the Seller in the
manner  set forth herein for the

<PAGE>

payment  of  the Purchase Price if the net
apportionment is  in  favor  of the Seller or by a
credit against  the Purchase  Price if the net
apportionment is in favor  of the Purchaser.  However,
if any of the items subject  to apportionment  under
the foregoing  provisions  of  this Section  3 cannot
be apportioned at the Closing  because of  the
unavailability of the information necessary  to
compute   such  apportionment,  or  if  any  errors
or
omissions in computing apportionments at the Closing
are discovered  subsequent to the Closing,  then  such
item shall  be
reapportioned and such errors  and  omissions
corrected as soon as practicable after the Closing
Date and  the proper party reimbursed, which
obligation shall survive  the Closing for a period of
one year after  the Closing  Date.
Notwithstanding any  of  the  foregoing
provisions  of  this Section 3.5 to  the  contrary,
the
     Purchaser  and  the  Seller  agree  that  the
     one  year limitation set forth in this Section
     3.5 shall not apply to  the parties' obligations
     under Sections                              3.1
     and  3.2
     and  that such obligations shall survive the
     Closing for the  period  of the statute of
     limitations in connection with such claims.
          <PAGE>
          3.6.  Tax Certiorari.

          Seller hereby acknowledges that tax
     proceedings are currently  pending  for  a
     reduction  in  the  assessed valuation  of  the
     Property for fiscal tax  years  1997, 1998,  1999
     and 2000.  Seller hereby covenants  that  it
     shall not, in connection with the proceedings
     referenced in  the prior sentence, take any
     action which would have any affect on the
     assessed value of the Property for the fiscal
     tax  years  2000  and later  without  the  prior
     written  consent of Purchaser, such consent  not
     to  be unreasonably withheld or delayed.
     4.  Due Diligence Period.

     Notwithstanding  anything  to  the  contrary
contained herein,  the  Purchaser shall have a Thirty
(30)  day  period commencing on the date hereof (the
"Due Diligence Period") to examine  title to the
Property, to inspect the  physical  and financial
condition  of  the  Property  and  to  review  the
Property    Information   (including,   without
limitation,
environmental  reports).   Neither  the  Purchaser
nor  the
Purchaser's   Representatives   shall   contact    (i)    any
governmental  authority  or  any  of  the  Seller's
vendors, employees,  consultants or contractors prior
to  the  Closing without  first notifying the Seller,
or (ii) any of  Seller's tenants,  without  (a)
obtaining the Seller's  prior  written consent  in
each  instance,  which  consent  shall  not
be
reasonably withheld, conditioned or delayed and (b)
arranging and  scheduling each such meeting with
Seller's tenants  with Seller or Seller's on-site
Property manager.


          4.1.  Access to the Property.

          During the Due Diligence Period, the
     Purchaser  and the Purchaser's Representatives
     shall have the right  to enter  upon  the
     Property  for  the  sole  purpose
     of
     inspecting   the  Property  and  making  surveys,
soil
     borings,  engineering  tests and  other
     investigations, inspections  and tests
     (collectively, "Investigations"), provided  (i)
     the Purchaser shall give the  Seller  not less
     than  two (2) business days' prior written
     notice before  each  entry, (ii) the first  such
     notice  shall include  sufficient information to
     permit the Seller  to review  the  scope  of the
     proposed Investigations,  and (iii)   neither
     the  Purchaser  nor  the
     Purchaser's
     Representatives shall permit any borings,
     drillings  or invasive  samplings to be done on
     the  Property  without the   Seller's  prior
     written  consent,   not   to
     be
     unreasonably  withheld,  conditioned  or
delayed. Any
     entry upon the Property and all Investigations
     shall  be during  the  Seller's normal business
     hours and  at  the sole   risk  and  expense  of
     the  Purchaser  and                          the
     Purchaser's Representatives, and Purchaser shall
     use all commercially  reasonable  efforts  so  as
     to  minimize
     interference  with  the  day-to-day  operation
of   the
     Property.  The Purchaser shall:

               (a)    promptly  repair  any  damage
to   the
Property  resulting  from any such
Investigations, refill   and   regrade
any  holes  made                           in,   or
excavations  of, any portion of the
Property  used for  such Investigations
so that the Property shall be  in
substantially the same  condition  as
that which existed prior to such
Investigations;

     (b)  fully comply with all Laws
applicable  to the   Investigations
and  all   other   activities
undertaken in connection therewith;
<PAGE>
     (c)     permit   the   Seller   to
have       a
representative  present during  all
Investigations undertaken hereunder;

     (d)   take all commercially
reasonable actions
and    implement   all   commercially
reasonable protections  necessary to
ensure that  all  actions taken  in
connection with the Investigations,
and the equipment, materials, and
substances generated, used or brought
onto the Property pose no threat to the
safety or health of persons or the
environment, and  cause                         no  damage  to
the  Property  or  other
property of the Seller or other
persons;

     (e)   only  in  the  event this
Agreement  is
terminated, if requested by the Seller
in  writing, furnish  to the Seller, at
Seller's sole  cost  and expense,
copies of all surveys, soil test
results, engineering,  asbestos,
environmental  and   other studies  and
reports relating to the Investigations
which  the  Purchaser shall obtain with
respect  to
the Property;

     (f)   maintain  or cause to be
maintained,  at
the  Purchaser's expense, a policy of
comprehensive general  public liability
insurance with a combined single  limit
of  not  less  than  $1,000,000  per
occurrence  for bodily injury and
property  damage,
automobile liability coverage including
owned  and hired  vehicles  with a
combined  single  limit  of $1,000,000          per  occurrence
for bodily  injury  and
property  damage, and an excess
umbrella  liability policy for bodily
injury and property damage in the
minimum   amount   of  $3,000,000,
insuring  the
Purchaser  and the Seller and certain
of  Seller's Affiliates                         listed  on
Schedule  4,  as  additional
insureds,  against  any  injuries  or
damages    to
persons  or  property that may result
from  or  are related                      to   (i)  the
Purchaser's   and/or                       the
Purchaser's   Representatives'   entry
upon the
Property,   (ii)   any  Investigations
or   other
activities   conducted  thereon  by
Purchaser  or
Purchaser's Representatives, and (iii)
any and  all other activities
undertaken by the Purchaser and/or the
Purchaser's Representatives in
connection with the   Property,  and
deliver  evidence   of   such insurance
policy to the Seller at the  earlier
of ten  (10) days after the date of
this Agreement  or the first entry on
the Property;

     (g)  indemnify  the Seller  and
the  Seller's Affiliates                        and  hold the
Seller and  the  Seller's
Affiliates  harmless from and against
any  and  all
     claims, demands, causes of action, losses,
     damages, liabilities, costs and expenses
     (including  without limitation   reasonable
     attorneys'    fees                          and
     disbursements), suffered or incurred by the
     Seller or  any  of  the Seller's Affiliates to
     the  extent arising  out  of  or  in connection
     with  (i)  any negligent or reckless

     <PAGE>
     acts   or   omissions  of  the   Purchaser
     and/or Purchaser's   Representatives   during
     (A)  the
     Purchaser  and/or  the Purchaser's
     Representatives' entry  upon  the Property or (B)
     any Investigations or                       other
     activities  conducted  thereon  by  the
     Purchaser  or the Purchaser's Representatives,
     and (ii)  any  liens or encumbrances filed or
     recorded against  the  Property  as  a
     consequence  of  the Investigations  or  any
     other activities  conducted thereon   by   the
     Purchaser  or  the  Purchaser's Representatives.
     Notwithstanding the foregoing, in no  event shall
     Purchaser indemnify Seller for  any pre-existing
     conditions  or  findings,  including, without
     limitation,  any violation  of  Applicable
     Environmental Law or the existence of any
     Hazardous Substance   discovered   during   the
     course
     of
     Purchaser's due diligence activities; and

          (h)  not,  at any time, contact or
     communicate with  any  tenant of the Property
     for  any  reason whatsoever  without the prior
     written  approval  of the
     Seller,  not  to  be  unreasonably  withheld,
     conditioned   or   delayed,  which
     communications, whether  by  telephone, in
     writing  or  in  person, Seller or its designee
     shall have the right  to  be present at or
     otherwise participate in.

     The  provisions of this Section 4.1  shall
survive the termination of this Agreement and the
Closing.
     4.2.  Purchaser's Termination Notice.

     Subject to the provisions of the last paragraph
of this Section 4.2, the Purchaser shall have the
right  to elect  to  terminate this Agreement  by
giving  written notice  (the "Purchaser's Termination
Notice")  of  such election to the Seller at any time
prior to 5:00 p.m. on the  last  day  of  the  Due
Diligence  Period  if  the Purchaser shall determine
(in the exercise of  its  sole and  exclusive
discretion) that Purchaser does not  wish to purchase
the Property.

     If  for any reason whatsoever the Seller shall
not have  received the Purchaser's Termination Notice
prior to  the  expiration  of  the Due Diligence
Period,  the Purchaser shall be deemed to have
irrevocably waived the right of termination granted
under this Section                              4.2,
and
such  right of termination shall be of no further
force or effect.
     4.3.  Estoppel Certificates.

     Promptly  after  execution  and  delivery  of
this Agreement,  the  Seller agrees to use  all
commercially reasonable  efforts  to obtain an
Estoppel  Certificate from  each tenant under a Lease
(as hereinafter  defined and  with  the  exception  of
the  Overlease)  dated  no earlier than thirty (30)
days prior to Closing,  but  in
     no  event shall it be deemed to be an obligation
     of  the Seller  under this Agreement to obtain
     executed Estoppel Certificates except for
     Estoppel Certificates  from  (i) all  tenants who
     lease space in excess of 10% of the net rentable
     area of
     <PAGE>
     each  of  the  Buildings, (ii)  one-half  of  all
     other tenants  at  the  Buildings,  and  (iii)
     the  following tenants:   (x) Nationwide
     Insurance; (y) Paging  Network and   (z)
     American  Home  Assurance.    The   Estoppel
     Certificates  shall  be in the form  annexed
     hereto  as Exhibit G and made a part hereof;
     provided, however,  if any  tenant is required or
     permitted under its Lease  to make  different
     statements in  a  certificate  of  such nature
     than are set forth in Exhibit G and Seller  first
     requests  that such tenant sign an Estoppel
     Certificate in  the form of Exhibit G and such
     tenant declines,  the Seller  may  modify  the
     Estoppel Certificate  for  such tenant  to set
     forth only the statements required  under such
     tenant's Lease to be made by such tenant in such
     a certificate.  If any tenant who is required  to
     deliver an  Estoppel  Certificate pursuant to
     this  Section  4.3 fails  to  deliver an Estoppel
     Certificate in  the  form required by this
     Agreement, Seller shall have the  right to
     substitute  in lieu thereof an estoppel
     certificate substantially in such form executed
     by Seller  and  such estoppel  certificate shall
     be treated for all  purposes as an Estoppel
     Certificate from such failing tenant.  In the
     event that after the Closing the Seller obtains
     and delivers  to the Purchaser an Estoppel
     Certificate  from any  tenant in the form
     required by this Section 4.3 for which the Seller
     has substituted an estoppel certificate executed
     by it at the Closing, then such Seller estoppel
     shall  be of no further force and effect and the
     Seller shall  thereafter  have no liability under
     such  Seller estoppel certificate.
     5.  Title.

     The  Seller shall convey and the Purchaser shall
accept title to the Property subject only to those
matters set forth on     Schedule   5   hereto
(collectively   the   "Permitted
Encumbrances").  The Purchaser has ordered at the
Purchaser's expense,  a  commitment for an owner's
fee  title  insurance policy  with respect to the
Property (the "Title Commitment") from  Commonwealth
Land Title Insurance Company  (the  "Title Company"),
together  with true and complete  copies  of  all
instruments giving rise to any defects or exceptions
to title to  the Property.  Purchaser shall instruct
the Title Company to  send  to  Seller's counsel a
copy of the Title Commitment and  all  related title
exception documents  to  Seller  upon receipt  of
same.  The Seller has delivered to the Purchaser, an
as-built  survey  which may, at  Purchaser's  option
and expense be updated, ("Survey") of the Land and
Buildings  and prepared  in  accordance  with the
"Minimum  Standard  Detail Requirements  for
ALTA/ACSM  Land  Title  Surveys"   jointly established
and adopted by ALTA and ACSM in 1992.
<PAGE>
          5.1.  Unacceptable Encumbrances.
          If  the Title Commitment or the Survey
     indicate the existence  of  any liens or
     encumbrances  (collectively, "Liens")  or other
     defects or exceptions in or to  title to  the
     Property other than the Permitted  Encumbrances
     (collectively, the "Unacceptable Encumbrances")
     subject
     to  which the Purchaser is unwilling to accept
     title and the Purchaser gives the Seller notice
     of the same within ten  (10)  business  days
     after  receipt  of  the  Title Commitment and the
     Survey, the Seller shall undertake to eliminate
     the  same (or to arrange for title  insurance
     insuring   against  enforcement  of  such
     Unacceptable Encumbrances against, or collection
     of the same out  of, the  Property)  subject to
     Section 5.2.   The  Purchaser hereby  waives  any
     right the  Purchaser  may  have  to advance  as
     objections to title or as grounds  for  the
     Purchaser's  refusal  to  close  this
     transaction     any
     Unacceptable  Encumbrance which the Purchaser
     does  not notify  the Seller of within such ten
     (10) business  day period  unless  (i)  such
     Unacceptable  Encumbrance  was first raised by
     the Title Company subsequent to the date of  the
     Title  Commitment and the Survey, respectively,
     and  (ii) the Purchaser shall notify the Seller
     of  the same  within  ten  (10) business days
     after  the  Title Company  first  notifies
     Purchaser of such  Unacceptable Encumbrance.
     The Seller, in its sole  discretion,  may adjourn
     the Closing one or more times for up  to  sixty
     (60)  days  in  the  aggregate  in  order  to
     eliminate Unacceptable Encumbrances.
   5.2.  Removal of Unacceptable Encumbrances.

          The  Seller  shall not be obligated  to
     bring  any action  or proceeding, to make any
     payments or otherwise to  incur any expense in
     order to eliminate Unacceptable Encumbrances not
     waived by the Purchaser or  to  arrange for title
     insurance insuring against enforcement of such
     Unacceptable Encumbrances against, or collection
     of  the same  out  of, the Property; except that
     the Seller,  at its  sole  cost  and  expense,
     shall  satisfy  and  cure Unacceptable
     Encumbrances which are (i) mortgages, UCC-1
     financing statements and past due real estate
     taxes  and assessments  secured by or affecting
     the  Property,  and (ii) judgments against the
     Seller or other Liens secured by  or  affecting
     the Property which judgments and other Liens  can
     be satisfied by payment of liquidated amounts not
     to  exceed $100,000 in the aggregate for  all
     such judgments and other Liens.  The Seller may
     eliminate any such  Unacceptable Encumbrance by
     the payment of amounts necessary  to  cause the
     removal thereof of  record,  by bonding  over
     such Unacceptable Encumbrance in a  manner
     reasonably satisfactory to the Purchaser or by
     arranging for  title  insurance  reasonably
     satisfactory  to  the Purchaser   insuring
     against   enforcement                          of
     such
     Unacceptable Encumbrance against, or collection
     of  the same out of, the Property.
<PAGE>
5.3  Options Upon Failure to Remove Unacceptable
Liens.

          If  the  Seller  is  unable  or  is  not
     otherwise obligated  (pursuant to Section 5.2)
     to  eliminate  all Unacceptable  Encumbrances not
     waived by the  Purchaser, or  to bond over in a
     manner reasonably satisfactory  to the  Purchaser
     any Unacceptable Encumbrances not  waived by  the
     Purchaser,  or to arrange for  title  insurance
     reasonably acceptable to the Purchaser insuring
     against enforcement  of such Unacceptable
     Encumbrances  against, or  collection of the same
     out of, the Property, and  to convey  title  in
     accordance with  the  terms  of  this Agreement
     on or before the Closing Date (whether or  not
     the  Closing  is adjourned as provided in Section
     5.1), the  Purchaser shall elect on the Closing
     Date,  as  its sole remedy for such inability of
     the Seller, either (i)
to  terminate  this  Agreement by notice
given  to  the Seller  pursuant  to Section
14.1, in  which  event  the provisions  of
Section 14.1 shall  apply,  or  (ii)  to
accept  title  subject to such Unacceptable
Encumbrances and  receive  no  credit
against, or reduction  of,  the Purchase
Price.
     5.3.  Use of Purchase Price.
     If  on  the Closing Date there may be
any Liens  or other   encumbrances  which
the  Seller  must  pay                                or
discharge in order to convey to the
Purchaser such title as is herein provided
to be conveyed, the Seller may use any
portion of the Purchase Price to satisfy the
same, provided:

          (a)  the Seller shall deliver to
     the Purchaser or  the  Title Company,
     at the Closing, instruments in
     recordable form and sufficient to
     satisfy  such Liens  (plus  penalties
     and interest,  if  any)  or other
     encumbrances of record together with
     the cost of recording or filing said
     instruments; or
          (b)  the Seller, having made
     arrangements with the  Title Company,
     shall deposit with said company
     sufficient moneys (plus penalties and
     interest,  if any)  acceptable  to
     said company  to  insure  the obtaining
     and the recording of such
     satisfactions. 5.4.  Franchise Taxes.
     Any  franchise  or corporate tax  open,
levied  or imposed against the Seller or
other owners in the  chain of  title  that
may be a Lien on the Closing Date  shall not
be an objection to title if the Title
Company omits same  from the title policy
issued pursuant to the Title Commitment  or
excepts same but insures  the  Purchaser
against collection thereof out of the
Property.
      5.5.  Transfer Taxes; Title Insurance
                    Premiums.

     At  the  Closing, the Seller shall pay
all transfer and                                      recording  taxes
(the  "Transfer  Tax  Payments")
imposed pursuant to the Laws of the State of
New York or any  other  governmental
authority  in  respect  of  the transactions
contemplated by this Agreement by  delivery
to  the  Title Company of sufficient funds
to  pay  such taxes  together  with  any
return  (the  "Transfer  Tax Returns")
required thereby which shall be duly
executed, and

<PAGE>

     acknowledged where necessary by the
Seller and  the Purchaser to the extent
required by applicable law.                           At
the  Closing,  the  premiums due the  Title
Company  to obtain title insurance policies
in the form contemplated by  the  Title
Commitment (as the same may  be  amended
pursuant  to this Agreement), the cost of
obtaining  the survey and other Closing-
related expenses shall be  paid in  the
manner  set forth on Schedule  6  hereto.            The
provisions  of  this Section 5.6 shall
survive  for  six months following the
Closing Date.
     5.6.  Bulk Sales.

     The Closing shall be consummated
without compliance with  bulk  sales laws.
If by reason of any  applicable bulk sales
law, any claims are asserted by creditors
of Seller  related  to periods prior to the
Closing,  such
     claims shall be the responsibility of Seller, and
     Seller shall  jointly and severally indemnify,
     defend and  hold harmless  Purchaser  (and  their

6. Representations and Warranties of the Seller.

     The  Seller represents and warrants to the
Purchaser  as follows:
          (a)   The  Seller  is  a duly  formed  and
validly
     existing general partnership organized under the
     laws of the State of New York and is qualified
     under the laws of the State of New York to
     conduct business therein.

          (b)   The  Seller has the full, legal right,
power
     and  authority to execute and deliver this
     Agreement and all  documents  now or hereafter to
     be executed  by  the Seller  pursuant  to  this
     Agreement (collectively,  the "Seller's
     Documents"),  to consummate  the  transaction
     contemplated  hereby,  and to  perform  its
     obligations hereunder and under the Seller's
     Documents.

     <PAGE>

          (c)   This Agreement and the Seller's
Documents  do
     not  and  will  not  contravene  any  provision
     of  the partnership   agreement  of  the
     Seller,   any   other agreements, documents or
     instruments to which the Seller is a party or may
     be bound, any judgment, order, decree, writ or
     injunction issued against the Seller, or, to the
     Seller's actual knowledge, any provision of any
     laws  or governmental ordinances, rules,
     regulations,  orders  or requirements
     (collectively, the "Laws")  applicable  to the
     Seller.   The  consummation  of  the
     transactions contemplated  hereby  will not
     result  in  a  breach  or constitute  a default
     or event of default by the  Seller under  any
     agreement to which the Seller or any  of  its
     assets  are  subject or bound and will not result
     in  a violation of any Laws applicable to the
     Seller.

          (d)   There  are  no leases, subleases,
tenancies,
     licenses  or other use or occupancy agreements
     affecting any  portion of the Property on the
     date hereof, or  any amendments  or modifications
     thereof, except  for  those items  listed in
     Schedule 7 annexed hereto  and  made  a part
     hereof (collectively, the "Leases").  The copies
     of the  Leases furnished by the Seller to the
     Purchaser are true  and  complete.  To the
     Seller's actual  knowledge, the  Leases  are in
     full force and effect,  without  any material
     default   by   the  Seller   and/or
     tenants
     thereunder.  To the Seller's actual knowledge,
     except as listed  on  Schedule  7, the Seller
     has  not  given  or received any notice of
     default which remains uncured  or unsatisfied,
     with respect to any of the Leases.   As  of the
     Closing  Date,  all of the leasing  commissions
     in connection with the Leases have been paid or
     satisfied.

          (e)  To the Seller's actual knowledge, there
     are no pending   actions,  suits,  labor
     disputes,  litigation proceedings or
     investigations to which the Seller  is  a party
     before any court or other governmental  authority
     with  respect  to the Property or Seller except
     as  set forth on Schedule 8 hereto.

     (f)   Except  as  disclosed on Schedule
9  hereto,
since  the date the Seller acquired legal
and beneficial title  to the Property (i) to
Seller's actual knowledge, neither  Seller
nor any third party has engaged  in  the
generation,  use,  manufacture, refinement,
production, transferring,  treatment,
storage  or  disposal  of  any Hazardous
Substance  (as hereinafter  defined)  on
the Property  in  violation of Applicable
Environmental  Law (as  hereinafter
defined), the cost  of  correction  or
remediation  of  which  would have  a
material  adverse effect  upon  the  value
of the Property,  and  (ii)  to Seller's
actual knowledge, neither Seller nor any
third party   has  received  any  written
notice     from   any
governmental  authority  having
jurisdiction  over  the Property,  nor  does
Seller have any knowledge,  of  any
violation of Applicable Environmental Law or
any  Permit with  respect to the Property
which requires  corrective action,  the cost
of which would have a material adverse
effect  upon  the value of the Property.
Disclosure  of any matter on Schedule 9
hereto shall not constitute any admission by
Seller that such matter was material  or  a
violation of Applicable Environmental Law.
As  used  in this  Agreement,  the term
"Hazardous  Substance"  shall mean  any
substance, chemical or waste that is
currently listed,  defined or referred to as
hazardous,  toxic  or dangerous  or  as  a
pollutant  or  contaminant   under
Applicable   Environmental  Law.   As   used   in   this
Agreement, the term "Applicable
Environmental Law" shall mean    the            Comprehensive
Environmental                                 Response,

Pollution  Control  Act, 33 U.S.C.  1251  et
seq.;  the Clean  Air  Act, 42 U.S.C.  7401
et seq.; and the  Toxic Substances  Control
Act, 15 U.S.C.   2601  et  seq.;  as the
foregoing have been amended from time to
time to the date  of this Agreement; and any
similar federal,  state and                    local  laws,
ordinances,  regulations,                      orders,
directives or requirements implementing such
statutes in effect   on  the  date  hereof
imposing  liability                            or
establishing  standards  of  conduct  for
environmental protection   or   in  any  way
related   to  Hazardous
Substances.

contracts,   union
contracts,  employment agreements  or  other
agreements affecting the Property or the
operation thereof,  except the Contracts as
defined in Section 8(c) below.  All  of the
Contracts  are  and will on  the  Closing
Date  be unmodified  and  to  Seller's
actual knowledge  in  full force and effect

any  of  the parties thereto, except those
Purchaser elects not to assume.  To Seller's
actual knowledge  all sums  presently  due
and payable by  Seller  under  the Contracts
have been fully paid and all sums which
become due  and payable between the date
hereof and the Closing Date  shall be fully
paid by Seller on the Closing  Date or,
with  respect to work being performed to
implement tenant   improvements,  any  lien
that   could   result therefrom  will have
been insured against by  the  Title Company.  Provided  that
Purchaser delivers  to  Seller
written notice of those Contracts Purchaser
shall assume at  Closing,  Seller  hereby
covenants  and  agrees  to
terminate  as  of the Closing Date those
Contracts  not being assumed by Purchaser.

receipt.

     (j)   To  Seller's  actual  knowledge,
Seller  has provided  Purchaser  with  (x)
all  reports,  including without
limitation,  the  Environmental  Documents,
in Seller's possession or under its control

which are or may be used by  Seller  in the

Personal  Property (collectively, and
together with  the Promotional   Materials,
the  "Books   and   Records").

Phase   I environmental reports in
connection with the Property in the

     (k)  Seller has no knowledge of any

     The  representations and warranties of
the  Seller set forth in this Section 6 (i)
shall be true,

<PAGE>

accurate  and correct in all material
respects upon  the execution  of this
Agreement and shall be deemed  to  be
repeated on and as of the Closing Date
(except  as  they relate  only to an earlier
date), and (ii) shall  remain operative  and
shall  survive  the  Closing                   and   the
execution and delivery of the Deed for a
period  of  six (6)  months  following the
Closing Date and  then  shall expire,  and
no action or claim based thereon  shall  be
commenced after such period.
     6.2.  Discovery of Untrue
Representation.
     If  at  or  prior to the Closing, (i)
the Purchaser shall  become  aware that any
of the representations  or warranties   made
herein  by  the  Seller  is   untrue,
inaccurate  or  incorrect in any  material
respect  and shall give the Seller notice
thereof at or prior to  the Closing,  or
(ii) the Seller shall notify the  Purchaser
that  a  representation or warranty made
herein  by  the Seller  is  untrue,
inaccurate or incorrect,  then  the Seller
may, in its sole discretion, elect by notice
to the  Purchaser to adjourn the Closing one
or more  times for  up to sixty (60) days in
the aggregate in order  to cure  or  correct
such untrue, inaccurate  or  incorrect
representation  or warranty.  If any such
representation or  warranty is not cured or
corrected by the Seller  on or  before the
Closing Date (whether or not the  Closing is
adjourned as provided above), then the
Purchaser, as its  sole  remedy  for such
inability of  Seller,  shall elect  either
(i)  to waive such misrepresentations  or
breaches  of  warranties and consummate the
transactions contemplated hereby without any
reduction of  or  credit against  the
Purchase Price, or (ii) to terminate  this
Agreement  by  notice given to Seller
pursuant  to  the provisions  of Section
14.1.  In the event  the  Closing occurs,      the   Purchaser
hereby   expressly   waives,
relinquishes and releases any right or
remedy  available to  it at law, in equity
or under this Agreement to make a   claim
against  the  Seller  for  damages  that
the Purchaser  may  incur, or to rescind
this Agreement  and the  transactions
contemplated hereby, as the result  of any
of the Seller's representations or
warranties being untrue,  inaccurate or
incorrect if the  Purchaser  knew that
such  representation  or  warranty  was
untrue, inaccurate  or incorrect at the time
of the Closing  and the Purchaser
nevertheless closes title hereunder.
     6.3.  Limited Nature of
Representations.

     The  Purchaser acknowledges that
neither the Seller nor  any  of the Seller's
Affiliates, nor any  of  their agents  or
representatives, nor  Broker  has  made  any
representations  or  held out  any
inducements  to  the Purchaser  other than
those specifically  set  forth  in this
Section   6  and  Section  11.    The          Purchaser
acknowledges that the Seller, pursuant to
the  terms  of this   Agreement,   has
afforded  the   Purchaser                      the
opportunity   for   full  and  complete
investigations, examinations  and
inspections of the Property  and  all
Property  Information.  The Purchaser
acknowledges  and agrees  that  (i) the
Property Information delivered  or made
available to the

<PAGE>

     Purchaser  and  the Purchaser's
Representatives  by the  Seller or the
Seller's Affiliates, or any of  their agents
or  representatives may have  been  prepared
by
     third  parties  and may not be the work product
of  the
     Seller  and/or  any  of  the Seller's
     Affiliates;  (ii) Seller  has advised that
     neither the Seller nor                     any
     of
     the   Seller's  Affiliates  has  made  any
     independent investigation  or verification of, or
     has any  knowledge of,  the  accuracy  or
     completeness  of,  the  Property Information
     (except that Seller represents that            it
     has
     provided  Purchaser  with true,  accurate  and
     complete copies of the Property Information in
     its possession  or control);  (iii) except as
     otherwise set  forth
     herein,
     the   Purchaser   is   relying   solely   on
its  own
     investigations,  examinations  and  inspections
of  the
     Property  and  those of the Purchaser's
     Representatives and   is                   not
     relying  in  any  way  on  the  Property
     Information  furnished  by the  Seller  or  any
of  the
     Seller's   Affiliates,  or  any  of  their
agents         or
     representatives; and (iv) the Seller expressly
     disclaims any  representations or warranties with
     respect    to  the
     accuracy  or  completeness of the  Property
     Information (except  that  Seller represents that
     it  has  provided Purchaser with true, accurate
     and complete copies of the Property Information
     in its possession or control), and, except  as
     otherwise  set forth herein,  the  Purchaser
     releases  the  Seller and the Seller's
     Affiliates,  and their  agents  and
     representatives, from  any  and  all liability
     with respect thereto.  The Purchaser or anyone
     claiming  by,  through  or under the  Purchaser,
     hereby fully  and  irrevocably  releases  the
     Seller  and  the Seller's Affiliates from any and
     all claims that it  may now  have or hereafter
     acquire against any of the Seller or       the
     Seller's  Affiliates  for  any  cost,   loss,
     liability,  damage, expense, action or cause of
action,
     whether  foreseen or unforeseen, arising from or
     related to  the presence of environmentally
     hazardous, toxic  or dangerous  substances, or
     any other conditions  (whether patent,  latent
     or otherwise) affecting  the  Property, except
     for  claims against the Seller  based  upon  any
     obligations  and  liabilities of  the  Seller
     expressly provided in this Agreement.

     The  provisions  of  this Section 6  shall
survive  the Closing.

     Purchaser,  or  any provision of any Laws
     applicable to the Purchaser.                         The
     consummation  of  the  transactions contemplated
     hereby will  not result in a breach or constitute
     a default  or event of default by the Purchaser

     not result in a violation of  any  Laws

10.1.  New Leases.

          Except  as  hereinafter provided  in  this
     Section 10.1,  the  Seller may modify, extend,
     renew, cancel  or permit  the  expiration of any
     Lease or enter  into  any proposed  Lease  of all

     Purchaser's consent; provided, however, that such
     Lease  is  on  Seller's standard  form  with
     such changes  as Seller deems appropriate in the
     exercise  of its  reasonable  discretion.  After
     the  execution  and delivery of this Agreement,
     the Seller shall not modify, extend,  renew or
     cancel (subject to Section  10.2)  any Lease  or
     enter into any proposed Lease of all  or  any
     portion  of  the Property without the Purchaser's

     after  receipt by the Purchaser of the Seller's
     notice, which  notice  shall set forth all the
     details  of  the transaction  sufficient  for
     Purchaser  to  make                           its

     relating to  such  existing or proposed Lease.
     If the  Purchaser fails to reply to the Seller's
     request for consent in  a notice  given  within
     such period or  if  the  Purchaser expressly
     denies its consent but fails to  provide  the
     Seller with the reasons for such denial, the
     Purchaser's consent shall be deemed to have been
     granted.
10.1.1.  New Lease Expenses.

               If  after  the  date  of this
          Agreement,  the Seller,  pursuant to Section
          10.1, enters into  any Leases  or  any
          extension, renewal,  expansion  or
          modification  of any Leases (where such
          extension, renewal,  expansion or
          modification is not provided for  in  such
          Lease), or if tenant  exercises  any
          extension,  renewal, expansion or
          modification  of any  Leases (each, a "New
          Lease"), the Seller shall keep    accurate
          records   of    all
          expenses
          (collectively,  "New Lease Expenses")
          incurred  in connection with each New Lease,
          including,  without limitation,
          the   following:    (i)
          brokerage
          commissions  and  fees  relating  to  such
          leasing transaction,  (ii) expenses incurred
          for  repairs, improvements,   equipment,
          painting,   decorating, partitioning  and
          other  items  to   satisfy               the
          tenant's  requirements with regard to such
          leasing transaction,  (iii)  reimbursements
          to  the  tenant for  the cost of any of the
          items described in  the preceding clause
          (ii), (iv) legal fees for services in
          connection with the preparation of documents
          and other  services  rendered in  connection
          with  the effectuation of the leasing
          transaction,  (v)  rent concessions relating
          to the demised space  provided the tenant
          has the right to take possession of such
          demised  space  during  the  period  of
          such  rent concessions,  and  (vi) expenses
          incurred  for  the purpose               of
          satisfying   or   terminating            the
          obligations  of a tenant under a New Lease
          to  the landlord  under another lease
          (whether or not  such other lease covers
          space in the Property).
10.1.2.  Allocation of New Lease Expenses.

               The  New  Lease  Expenses for each  New
          Lease allocable  to  and payable by the
          Seller  shall  be determined  by multiplying
          the amount of  such  New Lease  Expenses  by
          a fraction,  the  numerator  of which shall
          be the number of days contained in that
          portion,  if  any, of the term of  such  New
          Lease commencing   on  the  date  on  which
          the   tenant thereunder  shall have
          commenced to pay fixed  rent ("Rent
          Commencement Date") and expiring on the date
          immediately  preceding the Closing  Date,
          and  the denominator of which shall be the
          total  number  of days contained in the
          period commencing on the Rent
          Commencement Date and expiring on the date
          of  the scheduled expiration of the term of
          such New Lease, without  provision for any
          optional  extensions  or renewals, and the
     <PAGE>
               remaining  balance of the New  Lease
          Expenses for  each  New  Lease  shall be
          allocable  to  and payable  by  the
          Purchaser  by  addition  to
          the
          Purchase  Price.   At  the Closing,  the
          Purchaser shall  reimburse  the  Seller  for
          all  New  Lease Expenses theretofore paid by
          the Seller, if any, in excess  of  the
          portion of the New Lease  Expenses allocated
          to the Seller pursuant to the provisions of
          the  preceding sentence.  For purposes of
          this Section 10.1.2, the Rent Commencement
          Date under  a renewal, extension, expansion
          or modification of  a Lease  shall be deemed
          to be (i) in the case  of  a renewal or
          extension (whether effective prior to or
          after  the  Closing, or in the form  of  an
          option exercisable  in the future), the
          first date  during such   renewal  or
          extension  period   after
          the
          originally scheduled expiration of the term
          of such Lease on which the tenant under such
          Lease which is renewed,  extended, expanded
          on or  modified  after the  date hereof
          commences to pay fixed rent,  (ii) in  the
          case  of  an expansion (whether  effective
          prior to or after the Closing, or in the
          form of an option  exercisable  in the
          future),  the  date  on which the tenant
          under such Lease commences to  pay fixed
          rent for the additional space, and (iii)  in
          the  case  of  a modification not also
          involving  a renewal, extension or expansion
          of such Lease,  the effective date of such
          modification agreement.  The provisions of
          this Section 10.1.2 shall survive the
          Closing.

     <PAGE>
10.2.  Termination of Existing Leases.

          Notwithstanding anything to the contrary
     contained in this Agreement, the Seller reserves
     the right, but is not  obligated, to institute
     summary proceedings against any  tenant  or
     terminate any Lease as a  result  of  a default
     by  the tenant thereunder prior to the  Closing
     Date  with the prior written consent of
     Purchaser,  such consent  not  to  be
     unreasonably withheld  or  delayed; provided,
     however,  that  such  consent  will  not   be
     required  with respect to leases with Resource
     Mortgage and   AAT   Communications.    The
     Seller   makes   no representations  and  assumes
     no  responsibility   with respect  to (i) the
     continued occupancy of the  Property or
     any  part  thereof  by  any  tenant  and  (ii)
     the
     fulfillment by any tenant of its obligations
     under  any Lease.
     The  removal  of a tenant  whether  by  summary
     proceedings or otherwise prior to the Closing
     Date shall not give rise to any claim on the part
     of the Purchaser, provided  Seller has obtained
     Purchaser's prior  written consent  (as  provided
     in the first  sentence  of  this Section 10.2)
     for such summary proceedings or otherwise, and
     provided further that no such consent from
     Purchaser shall  be  required with respect to
     leases with Resource Mortgage  and AAT
     Communications. Further, the Purchaser agrees
     that it shall not be grounds for the Purchaser's
     refusal to close this transaction that any tenant
     is  a
     holdover  tenant or in default under its Lease
     pursuant to  any  economic or non-economic terms
     of its Lease  on the  Closing  Date and the
     Purchaser shall accept  title subject  to such
     holding over or default without  credit against,
     or reduction of, the Purchase Price.  The terms
     of   this  Section  10.2  are  not  applicable
     to   the
     Overlease,   which   Purchaser   recognizes
     shall   be terminated  at  Closing  pursuant  to
     the  Termination, Assignment and Recognition
     Agreement.
10.3.  Contracts.

          Except  as  hereinafter provided  in  this
     Section 10.3,  the Seller may cancel, modify,
     extend,  renew  or permit the expiration of
     Contracts or enter into any new Contract without
     the Purchaser's prior consent but  only after
     giving   Purchaser   prior   notice   of    such
     cancellation,  modification, extension or
     renewal.  Any new  Contracts  entered into
     between the  date  of  this Agreement and the
     expiration of the Due Diligence Period will  be
     terminable at or prior to the Closing  without
     charge or penalty to Purchaser.  After the
     expiration of the  Due  Diligence Period, the
     Seller shall not modify, extend, renew or cancel
     (except as a result of a default by  the  other
     party thereunder or if the Purchaser  has given
     notice pursuant to Section 6(g) that a Contract
     is not  to be assumed) any Contracts, or enter
     into any new Contract without the Purchaser's
     prior consent  in  each instance,   which
     consent  shall  not  be  unreasonably withheld
     or  delayed,  and if withheld,  the  Purchaser
     shall

     <PAGE>
          promptly  give  the  Seller a  notice
     stating  the reasons therefor. If the Purchaser
     fails to reply within five  (5) days to the
     Seller's request for consent in  a notice  given
     pursuant to this Section 10.3  or  if  the
     Purchaser  expressly  denies its consent  but
     fails  to provide the Seller with the reasons for
     such denial, the Purchaser's  consent  shall  be
     deemed  to  have   been granted.
10.4.  Operation and Maintenance of Property.

          The  Seller  covenants and agrees that
     between  the date  hereof  and  the  Closing Date
     the  Seller  shall perform or observe the
     following:

               (a)  Seller shall not:
                    (i)   Enter  into any agreement
               requiring Seller  to  do work for any
               tenant  after  the Closing Date without
               first obtaining the prior written
               consent of Purchaser;
                    (ii)  Apply  any Security
               Deposits  with respect  to  any  tenant
               in occupancy  on  the Closing Date;
                    (iii)      Remove  any Personal
               Property located in or on the Property,
               except  as  may be  required for repair
               and replacement.                           All
               replacements shall be free and clear of
               liens and  encumbrances and shall be of
               quality  at least equal to the replaced
               items and shall be deemed included in
               this sale, without cost  or expense to
               Purchaser; or

                    (iv) Cause or permit the Property,
               or any interest  therein, to be
               alienated, mortgaged, licensed,
               encumbered   or   otherwise                 be
               transferred.

               (b)   Up  to  and including the Closing
          Date, Seller  agrees  to maintain and keep
          such  hazard, liability and casualty
          insurance policies  in  full force and
          effect in such amounts and covering  such
          risks  sufficiently to protect the Property
          and  to protect,  to  a reasonable and
          prudent extent,  the owner  of  the
          Property, in such  amounts  as  are required
          so as not to be deemed a co-insurer,  and
          for  actual  replacement cost,  against  any
          loss, damage, claim or liability.

               (c)  Seller shall cancel, at its sole
          cost and expense, those Contracts which
          Purchaser elects not to assume.

               (d)   Seller  shall permit Purchaser
          and  its authorized representatives to
          inspect the Books and Records of its
          operations at all reasonable  times. All
          Books  and Records not conveyed  to
          Purchaser hereunder   shall  be  maintained
          for  Purchaser's inspection at Seller's
          address as set forth above.

               (e)    Seller   shall  promptly
notify    the
          Purchaser  of, and shall also promptly
          deliver  to the  Purchaser, a certified true
          and complete  copy of  any Notice the Seller
          may receive, on or before the  Closing Date,
          from any Governmental Authority, concerning
          a violation of Applicable Environmental Laws
          or discharge of Hazardous Substances.

arising  out   of   the   transactions contemplated

11.1.  Damage or Destruction.
          If  a  "material" part (as hereinafter
     defined)  of the  Property is damaged or
     destroyed by fire  or  other casualty, the Seller
     shall notify the Purchaser of  such fact  and
     the  Purchaser  shall  have  the  option             to
     terminate this Agreement upon notice to the
     Seller given not  later  than  ten  (10) days
     after  receipt  of  the Seller's notice.  If (i)
     the Purchaser does not elect to terminate this
     Agreement as to the damaged Property,  or (ii)
     there  is  damage  to  or  destruction
     of       an
     "immaterial" part ("immaterial" is herein deemed
     to  be any  damage  or destruction which is not
     "material",  as such  term is hereinafter
     defined) of the Property,  the Purchaser  shall
     close  title  as  provided   in   this Agreement
     and, at the Closing, the Seller shall,  unless
     the Seller has repaired such damage or
     destruction prior to  the  Closing,  (x)  pay
     over to  the  Purchaser  the proceeds  of any
     insurance collected by the Seller  plus any
     deductible less the amount of all costs incurred
     by the  Seller in connection with the repair of
     such damage or  destruction,  and  (y) assign and
     transfer  to  the Purchaser all right, title and
     interest of the Seller in and  to  any
     uncollected insurance proceeds  which  the Seller
     may be entitled to receive from such  damage  or
     destruction.  A "material" part of the Property
     shall be deemed to have been damaged or destroyed
     if the cost  of repair or replacement shall
     exceed $500,000.
11.2.  Condemnation.

          If,   prior  to  the  Closing  Date,  all
or   any
     "significant"  portion (as hereinafter defined)
     of  the Property is taken by eminent domain or
     condemnation  (or is  the  subject of a pending
     taking which has not  been consummated),  the
     Seller  shall  promptly  notify  the Purchaser of
     such fact and the Purchaser shall have  the
     option  to terminate this Agreement upon notice
     to  the Seller  given not later than ten (10)
     days after receipt of the Seller's notice.  If
     the Purchaser does not elect to  terminate  this
     Agreement, or if an  "insignificant" portion
     ("insignificant" is herein  deemed  to  be  any
     taking  which  is  not "significant", as  such
     term  is herein  defined)  of the Property is
     taken  by  eminent domain or condemnation, at the
     Closing the Seller  shall assign and turnover,
     and the Purchaser shall be entitled to  receive
     and keep, all awards or other proceeds  for such
     taking  by  eminent  domain  or  condemnation.
     A "significant"  portion  of the Property  means
     (i)  any portion  of  the  Buildings, (ii)  any
     portion  of  the parking areas, or (iii) any
     legally required driveway on the Land.

          If   the  Purchaser  effectively  terminates
     this Agreement  pursuant  to  Section  12.1  or
     12.2,   this Agreement  shall  be terminated and
     the  rights  of  the parties  shall  be the same
     as if notice of  termination were given pursuant
     to Section 14.1.  The provisions  of this
     Section 12 are intended to supercede  and
     replace any inconsistent or conflicting
     provisions set forth  in Section  5-1311 of the
     General Obligations  Law  of  the State of New
     York.

13.  Remedies.
13.1.  Seller's Inability to Perform.

          If  the  Closing fails to occur by  reason
     of  the Seller's inability to perform its
     obligations under this Agreement which has not
     been waived pursuant to  Section
     13.3,  then the Purchaser, as its sole remedy
     for  such inability of the Seller, may terminate
     this Agreement by notice  to  the  Seller.   If
     the  Purchaser  elects  to terminate this
     Agreement, then this Agreement  shall  be
     terminated  and  neither party shall  have  any
     further rights, obligations or liabilities
     hereunder other  than those  obligations, rights
     and liabilities which by  the terms   of   this
     Agreement  expressly                  survive the
     termination   of   this   Agreement   (the
"Surviving
     Obligations"),  and except that the Purchaser
     shall  be entitled  to  a  return  of  the
     Deposit  provided  the Purchaser is not otherwise
     in default hereunder.  Except as  set forth in
     this Section 14.1, the Purchaser hereby expressly
     waives, relinquishes and releases  any  other
     right  or  remedy available to it at law, in
     equity  or otherwise by reason of the Seller's
     inability to perform its obligations hereunder.
     Notwithstanding anything  to the  contrary
     herein,  if  the  Seller's  inability  to perform
     its obligations under this Agreement is a result
     of any action of, or failure to act by, the
     Purchaser or any  of  the Purchaser's
     Representatives, the  Purchaser shall  not  be
     relieved of its obligations  under  this
     Agreement  and  Purchaser shall not be entitled
     to  any right  or  remedy  provided  in  this
     Section  14.1  or elsewhere in this Agreement.
13.2.  Purchaser's Failure to Perform.

          In   the  event  of  a  default  hereunder
     by  the Purchaser or if the Closing fails to
     occur by reason  of the  Purchaser's  failure  or
     refusal  to  perform  its obligations  hereunder,
     then the  Seller  may  terminate this  Agreement
     by  notice to the  Purchaser.              If
     the
     Seller  elects  to terminate this Agreement,
     then  this Agreement shall be terminated and the
     Seller may  retain the  Deposit as liquidated
     damages for all loss,  damage and  expenses
     suffered by the Seller, it  being  agreed that
     the  Seller's damages are impossible to
     ascertain, and   neither  party  shall  have  any
     further  rights, obligations  or  liabilities
     hereunder, except  for  the Surviving
     Obligations.  Nothing contained herein  shall
     limit  or  restrict the Seller's ability to
     pursue  any rights  or  remedies it may have
     against  the  Purchaser with  respect to the
     Surviving Obligations.                Except  as
     set  forth  in  this  Section  14.2  and  the
     Surviving Obligations,                     the
     Seller  hereby  expressly
     waives,
     relinquishes  and  releases any other  right  or
     remedy available  to  them at law, in equity  or
     otherwise  by reason  of  the  Purchaser's
     default  hereunder  or  the Purchaser's
     failure   or  refusal                 to
     perform its
     obligations hereunder.  Notwithstanding anything
     to  the contrary  herein,  if  the Purchaser's
     default  or  the Purchaser's
     failure   or  refusal                 to
     perform its
     obligations  under this Agreement is  a  result
     of  any action  of, or failure to act by, the
     Seller or  any  of the  Seller's  Affiliates,
     the  Seller  shall  not                    be
     relieved of its obligations under this Agreement
     and the Seller  shall  not be entitled to any
     right  or  remedy provided  in  this  Section
     14.2 or  elsewhere  in  this Agreement.

     <PAGE>
13.3.  Seller's Failure to Perform.

          If  the  Closing fails to occur by  reason
     of  the Seller's  failure or refusal to perform
     its  obligations hereunder                 or
     due  to  the  willful  breach   of    any
     representation  or warranty set forth herein
     which  has not been waived by the Purchaser, then
     the Purchaser, as its  sole  remedy  hereunder,
     may  (i)  terminate  this Agreement by notice to
     the Seller or (ii) seek  specific performance
     from the Seller.  As a condition  precedent to
     the  Purchaser exercising any right it may  have
     to bring  an action for specific performance as
     the  result of  the  Seller's  failure or refusal
     to  perform  their obligations hereunder, the
     Purchaser must commence  such an  action  within
     ninety (90) days after the occurrence of  such
     default.  The Purchaser agrees that its failure
     to   timely   commence  such  an  action  for
     specific
     performance within such ninety (90) day period
     shall  be deemed  a waiver by it of its right to
     commence such  an action.    Notwithstanding
     anything  to  the
     contrary
     herein,  if  the Seller's failure or refusal to
     perform its  obligations under this Agreement is
     a result of any action of, or failure to act by,
     the Purchaser or any of the Purchaser's
     Representatives, the Purchaser shall not be
     relieved of its obligations under this Agreement
     and Purchaser  shall not be entitled to any right
     or  remedy provided  in  this  Section 14.3 or
     elsewhere  in  this Agreement.  Notwithstanding
     the above provisions, in the event  Seller
     voluntarily  transfers  or  conveys
     the
     Property  to a third-party purchaser during the
     pendency of  this  Agreement and prior to
     Closing, Purchaser  may bring a claim against
     Seller for money damages, provided that  such
     damages shall not, in any event  exceed  One
     Million Dollars ($1,000,000.00).

<PAGE>
     14.  Escrow.
     The  Escrow  Agent  shall hold the Downpayment
and  all interest   accrued   thereon,  if  any
(collectively,
the
"Deposit") in escrow and shall dispose of the Deposit
only in accordance  with  the  provisions  of  that
certain   Escrow Agreement  of  even  date herewith by
and  among  the  Escrow Agent,  the Purchaser and the
Seller relating to the Property (the  "Escrow
Agreement") in the form of Exhibit  I  hereto.
Simultaneously  with  their execution and  delivery
of  this Agreement,  the  Purchaser and the Seller
shall  furnish  the Escrow  Agent with their true
Federal Taxpayer Identification Numbers so that the
Escrow Agent may file appropriate  income tax
information returns with respect to any interest
earned on  or  credited to the Deposit.  The party
entitled  to  the economic   benefit  of  the  Deposit
shall  be   the   party responsible for the payment of
any tax due on the interest on the Downpayment.

     The provisions of the Escrow Agreement shall
survive the termination of this Agreement and the
Closing.

     18.  Assignments.

     This Agreement shall be binding upon and

hereto and to their  respective heirs,
executors, administrators, successors  and
permitted assigns.  This Agreement may not be
assigned by the Purchaser except  to  an
affiliate of Purchaser (any  such  entity,  a
"Permitted  Assignee").   Any other assignment
or  attempted assignment  by  Purchaser  shall
constitute  a  default                                     by
Purchaser hereunder and shall be deemed null and
void and  of no  force and effect.  No assignment
of this Agreement  shall relieve  Purchaser from
its obligations under this Agreement. For
purposes of this Section 19, "affiliate" shall
mean  any other  person or entity that directly,
or indirectly  through one or more
intermediaries, controls, is controlled by or  is
under common control with the specified person or
entity.  As used  in  this  definition,
"control",  "controlled  by"  and "under common
control with" shall mean the power, directly or
indirectly, to direct or cause the direction of
management or policies  of  such  person
(whether  through  ownership                               of
securities  or  other partnership or ownership
interests,  by contract or otherwise); provided,
however, that in any event, any  person  which
owns directly, indirectly or  beneficially fifty-
one  percent  (51%) or more of  the  securities
having voting power for the election of directors
or other governing body  of a corporation or
fifty-one percent (51%) or more  of
the  general partnership interests or fifty-one
percent (51%) or  more  of  the  managing
membership  interests  or  other ownership           interests of any
other person will  be  deemed  to
control such person.
     19.  Entire Agreement, Amendments.
     All  prior  statements, understandings,
representations and  agreements  between the
parties, oral  or  written,  are superseded by
and merged in this Agreement, which alone fully
and  completely  expresses  the  agreement
between  them  in connection  with this
transaction and which is  entered  into after
full  investigation, neither party  relying  upon
any statement, understanding, representation or
agreement made by the  other  not  embodied in
this Agreement.  This  Agreement shall  be           given  a  fair  and
reasonable  construction                             in
accordance  with  the intentions of the parties
hereto,  and without  regard  to  or aid of
canons requiring  construction against  the
Seller  or the party drafting  this  Agreement.
This  Agreement  shall  not  be  altered,
amended,  changed, waived,  terminated or
otherwise modified in any  respect  or
particular,  and no consent or approval required
pursuant  to this  Agreement shall be effective,
unless the same shall  be in  writing  and signed
by or on behalf of the  party  to  be charged.
     20.  Merger.

     Except  as  otherwise  expressly  provided
herein,  the Purchaser's  acceptance  of  the

obligations of the Seller  hereunder
and   all   of   the  Seller's  representations,
warranties,
covenants  and agreements herein shall merge in

     22.  Miscellaneous.

State  of  New  York  without  reference  to
principles                                            of
conflicts of laws.
     23.  Time of the Essence.

24.  IRS Form 1099-S Designation.

     In   order   to   comply   with  information
reporting requirements of Section 6045(e) of the

the Treasury Regulations thereunder, the
parties  agree  (i)  to  execute  an  IRS  Form
1099-S Designation Agreement in the form attached
hereto as  Exhibit K  at  or prior to the Closing
to designate the Title Company as  the  party
who  shall be responsible for  reporting  the
contemplated  sale  of the Property to the
Internal  Revenue Service  (the "IRS") on IRS
Form 1099-S; (ii) to provide  the Title Company
with the information necessary to complete Form

<PAGE>

1099-S; (iii) that the Title Company shall not be
liable  for the   actions  taken  under  this
Section  25,  or  for  the consequences  of
those actions, except as they  may  be  the
result of gross negligence or willful misconduct
on the  part of  the Title Company; and (iv) that
the Title Company  shall be  indemnified  by  the
parties for any  costs  or  expenses incurred as
a result of the actions taken under this  Section
25,  except as they may be the result of gross

proceeding against the other relating to  this
Agreement or any default hereunder, then and in
that event the prevailing party in such action or
proceeding shall
be  entitled  to recover from the other party its
reasonable attorneys' fees which shall be deemed
to have accrued on  the commencement  of  such
action or  proceeding  and  shall                         be
payable whether or not such action is prosecuted
to judgment. The provisions of this Section 26
shall survive Closing.
26.  Counterparts.

     This Agreement may be executed by the
parties hereto                                            in
separate  counterparts, each of which when  so
executed  and delivered  shall  be  deemed  an
original,  but   all                                     such
counterparts shall together constitute but one
and  the  same instrument.
27.  Tax Free Exchange.

     Purchaser may consummate the purchase of the
Property as part  of  a  so  called like kind
exchange  (the  "Exchange") pursuant  to  1031 of
the Internal Revenue Code of  1986,                       as
amended  (the  "Code"), provided that: (i) the
Closing  shall not  be  delayed  or affected by
reason of the  Exchange  nor shall the
consummation or accomplishment of the Exchange be
a condition  precedent or condition subsequent
to  Purchaser's obligations under this Agreement;
(ii) Purchaser shall effect the  Exchange through
an assignment of this Agreement, or its rights
under  this  Agreement, to a qualified
intermediary; (iii)  Seller shall not be required
to take an assignment                                     of
the  purchase agreement for the relinquished
property  or                                             be
required  to  acquire or hold title to any real
property  for purposes  of  consummating the
Exchange; and  (iv)  Purchaser shall pay any
additional costs that would not otherwise  have
been  incurred  by  Purchaser or  Seller  had
Purchaser  not consummated its purchase through
the Exchange.  Seller  shall not  by  this
agreement or acquiescence to the Exchange  (1)
have  its  rights under this Agreement affected
or diminished in any manner or (2) be responsible
for compliance with or be deemed  to  have
warranted to Purchaser that the Exchange                  in
fact complies with 1031 of the Code.
28.  Termination of Overlease and Assignment of
KLM Lease.
At  Closing,  Seller,  KLM, Sublandlord and

party  to  this Agreement shall, from time to
time, execute, acknowledge  and deliver such
further instruments, and perform such additional
acts,  as the other party may reasonably request
in order      to
effectuate   the  Closing  contemplated  by  this
Agreement. Nothing contained in this Agreement
shall be deemed to create any  rights  or
obligations of partnership, joint venture                 or
similar association between Seller and Purchaser.

     2.    Due  Diligence  Period.  The  first  sentence  in
Section  4 of the Agreement shall be deleted in its entirety
and  the  following  sentence shall  be  inserted  in  place
thereof:

     "Notwithstanding  anything to  the  contrary  contained
herein,  the  Purchaser shall have a thirty-seven  (37)  day
