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 40.6% by Dean Witter Realty Income
Partnership IV,  L.P.  (the  "Partnership"), 44.6% by
Dean Witter  Realty Income   Partnership   III,  L.P.,
an   affiliated   public partnership,   and  14.8%  by
Dean  Witter   Realty   Income Partnership II, L.P., an
affiliated public partnership.
The  purchase price was paid in cash at closing.  At
closing, the   Partnership   received  approximately
$13.5   million representing its 40.6% 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  March  31, 2000, the  Partnership's
Balance Sheet  as  of  such date would have reflected an
increase  in cash and cash equivalents from $1.9 million
to $15.4 million, the  elimination  of  the $8.6 million
investment  in  joint venture  and  the $0.1 million
other assets, an  increase  in accounts payable and
accrued liabilities from $0.1 million to $0.2  million
and an increase in partner's capital from $10.5 million
to $15.2 million.

For  the  Income  Statement for the quarter ended  March
31, 2000,  if  the  Property was sold on January  1,
2000,   the equity in earnings of joint venture of
approximately $112,000 would  have  been eliminated and
the Partnership  would  have incurred  net  income  of
approximately  $10,000($0.03   per limited partnership
unit).

For  the  Income  Statement for the year ended  December
31, 1999, if the Property was sold on January 1, 1999,
the equity in  earnings  of  joint  venture would  have
decreased  from $470,000 to $147,000 and net income would
have decreased from approximately  $363,000 ($1.10 per
limited partnership  unit) to $40,000 ($0.15 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.

     (h)   personal property taxes, if any, on the basis
of the fiscal year for which assessed;

     (i)   all other revenues from the operation of  the

(including, without limitation, parking charges,  tenant
direct electrical reimbursements, HVAC overtime charges,

     (j)   New  Lease  Expenses as provided  in  Section

     (l)    such   other   items  as   are   customarily
apportioned  between  sellers  and  purchasers  of  real
properties of a type similar to the Property and located
in Westchester County, New York.
     3.1.  Taxes.

     If   the  amount  of  real  estate  taxes,  special
assessments  or  other taxes for the  Property  for  the
fiscal  year  during  which the Closing  occurs  is  not
finally  determined at the Adjustment Date,  such  taxes
shall be apportioned on the basis of the full amount  of
the  assessment  for such period (or the assessment  for
the  prior tax period if the assessment for the  current
tax  period  is  not then known) and the  rate  for  the
immediately  prior tax year, and shall be  reapportioned
as  soon as the new tax rate and valuation, if any,  has
been  finally determined.  If any taxes which have  been
apportioned shall subsequently be reduced by  abatement,
the amount of such abatement, less the cost of obtaining
the  same and after deduction of sums payable to tenants
under  Leases or expired or terminated Leases, shall  be
equitably apportioned between the parties hereto.
     3.2.  Rents.
          3.2.1.  Arrearages.

          If  on  the  Closing Date  any  tenant  is  in
     arrears in the payment of Rent or has not paid  the
     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
Closing,  Seller  shall  deliver  to  Purchaser   a
schedule of any Rents in arrears as of the  Closing
Date.
     3.2.2.  Additional Rents.
     If  any tenants are required to pay percentage
rent,  escalation  charges for real  estate  taxes,
parking charges, operating expenses and maintenance
escalation   charges,   cost-of-living   increases,
utility,  sewer or water charges or other  charges,
however characterized ("Additional Rents") and  any
Additional  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  respective  directors,
     officers, employees, affiliates, successors and assigns)
     from  and  against  all losses or liabilities,  if  any,
     based  upon, arising out of or otherwise in  respect  of
     the failure to comply with such bulk sales laws.
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,
Compensation  and  Liability Act ("CERCLA"),  42  U.S.C.
9601 et seq.; the Resource Conservation and Recovery Act
("RCRA"),   42   U.S.C.   6901,  et  seq.;   the   Water
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.

     <PAGE>

     (g)    There   are  no  service  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 without any default or claim of default
by  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.

     (h)    The   Licenses  include  all   certificates,
licenses,  permits and authorizations,  including  those
relating  to  any  environmental matters,  necessary  to
operate  and  occupy the Buildings  and  are  listed  on
Schedule  11.  Seller has not received any  notice  that
any  of the Permits and Licenses are subject to,  or  in
jeopardy  of,  revocation  or  non-renewal.   Seller  is
current  in the payment of any fees required to be  paid
for  the permits and licenses.  All permits and licenses

the  roads providing a means of ingress or egress to the
Property.   Seller  agrees to furnish Purchaser  with  a
copy  of  any such notice received within two  (2)  days
after receipt.

     (j)   To  Seller's  actual  knowledge,  Seller  has
provided  Purchaser  with  (x)  all  reports,  including

by  Seller  in the use and operation of the Property  or
Personal  Property (collectively, and together with  the
Promotional   Materials,  the  "Books   and   Records").
"Environmental  Documents"  shall  mean  all   Phase   I
environmental reports in connection with the Property in
the possession of Seller.
     (k)  Seller has no knowledge of any violations,  or
of  any  notices,  suits,  investigations  or  judgments
relating   to   any   violations   (including,   without
limitation, Environmental Laws), or any laws, ordinances
or regulations affecting the Property, or any violations
or conditions that may give rise thereto.

     (l)  To the Seller's knowledge, there are no tenant
improvement  obligations affecting the Property  on  the
date  hereof, except for those items listed in  Schedule
12 annexed hereto and made a part hereof.
     6.1.  Survival of Representations.

     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.
     7.  Representations and Warranties of the Purchaser.

     The  Purchaser represents and warrants to the Seller  as
follows:

          (a)   The  Purchaser is a duly formed  and  validly
     existing  corporation organized under the  laws  of  the
     State  of Delaware, and is qualified under the  laws  of
     the State of New York to conduct business therein on the
     date hereof.

     <PAGE>

          (b)   The  Purchaser  has the  full,  legal  right,
     power,  authority and financial ability to  execute  and

     to  perform  its  obligations hereunder  and  under  the
     Purchaser's Documents.

     Laws of the Purchaser, any judgment, order, decree, writ

     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 under any agreement to
     which the Purchaser or any of its assets are subject  or
     bound  and  will not result in a violation of  any  Laws
     applicable to the Purchaser.

          (d)    There   are   no  pending  actions,   suits,
     proceedings or investigations to which the Purchaser  is
     a party before any court or other governmental authority
     which  may  have  an adverse impact on the  transactions
     contemplated hereby.

     The  representations and warranties of the Purchaser set
forth in this Section 7 and elsewhere in this Agreement shall
be  true, accurate and correct in all material respects  upon
the  execution  of  this Agreement, shall  be  deemed  to  be

     Between the date hereof and the Closing Date, the Seller

and  maintain the Property in the ordinary course of business
and   use   commercially  reasonably  efforts  to  reasonably
preserve  for  Purchaser  the  relationships  of  Seller  and
Seller's  tenants, suppliers, managers, employees and  others
having on-going relationships with the Property.
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 or any portion of  the  Property
     without the 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  prior
     consent  in  each instance, which consent shall  not  be
     unreasonably withheld and shall be given or denied, with
     the  reasons for any such denial, within seven (7)  days
     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
     decision, including,

     the  Purchaser's consent to the proposed action 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.

     <PAGE>

     10.4.1. Broker.

     The  Purchaser and the Seller represent and  warrant  to
each other that Insignia/ESG, Inc. (the "Broker") is the sole
broker  with  whom  they have dealt in  connection  with  the
Property  and the transactions described herein.  The  Seller
shall  be  liable  for,  and shall  indemnify  the  Purchaser
against, all brokerage commissions or other compensation  due
to  the Broker arising out of the transaction contemplated in
this Agreement, which compensation shall be paid subject  and
pursuant to a separate agreement between the Seller  and  the
Broker.   Each party hereto agrees to indemnify,  defend  and
hold  the other harmless from and against any and all claims,
causes  of  action,  losses,  costs,  expenses,  damages   or
liabilities,   including  reasonable  attorneys'   fees   and
disbursements,  which  the other may  sustain,  incur  or  be
exposed  to, by reason of any claim or claims by any  broker,
finder  or other person, except (in the case of the Purchaser
as indemnitor hereunder) the Broker, for fees, commissions or
other   compensation   arising  out   of   the   transactions
contemplated  in this Agreement if such claim or  claims  are
based in whole or in part on dealings or agreements with  the
indemnifying party.  The obligations and representations  and
warranties  contained in this Section 11  shall  survive  the
termination of this Agreement and the Closing.

11.  Casualty; Condemnation.
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.
11.3.  Termination.

          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.
15.  Notices.

objections, requests or other communications which the Seller

Representatives who need to know the Property Information for

by  the  Purchaser of the confidential nature of the Property
Information.  Purchaser shall be liable  for  any  breach  of
either or both of this Section 17 or Section 6.3 by Purchaser

Section  17  shall in no event apply to Property  Information
which is a matter of public record and shall not prevent  the
Purchaser  from  complying  with  Laws,  including,   without
limitation,  governmental  regulatory,  disclosure,  tax  and
reporting requirements.
16.1.  Press Releases.

          The  Purchaser and Seller, for the benefit of  each
     other, hereby agree that between the date hereof and the
     Closing  Date, they will not release or cause or  permit

     or  cause or permit to be announced or disclosed, in any

     this  Agreement or the transactions contemplated herein,
     without first obtaining the written consent of the other
     party  hereto. It is understood that the foregoing shall
     not  preclude either party from discussing the substance
     or any relevant details of the transactions contemplated
     in   this   Agreement   with  any  of   its   attorneys,
     accountants,   professional  consultants  or   potential
     lenders,  as  the case may be, or prevent  either  party
     hereto  from  complying  with Laws,  including,  without
     limitation, governmental regulatory, disclosure, tax and
     reporting requirements.
16.2.  Return of Property Information.

     Purchaser shall promptly deliver to the Seller a  letter
     signed  by  Purchaser certifying that  all  commercially
     reasonable  efforts  have  been  made  by  Purchaser  in
     connection  with the return to Seller of  all  originals

     Information  then in the possession of  Purchaser  after
     having   made  such  commercially  reasonable   efforts.
     Notwithstanding  anything  contained   herein   to   the
     contrary, in no event shall the Purchaser be entitled to
     receive  a  return  of the Downpayment  or  the  accrued
     interest thereon, if any, if and when otherwise entitled
     thereto  pursuant to this Agreement until such  time  as
     the  Purchaser  shall  have  performed  the  obligations
     contained in the preceding sentence.
16.3.  Property Information Defined.

          As  used  in  this  Agreement, the  term  "Property

     operation   thereof  or  the  sale  thereof  (including,
     without  limitation, Leases, Contracts and Licenses  and
     Environmental Documents) furnished by the Seller or  any
     of   the   Seller's  Affiliates,  or  their  agents   or

16.4.  Remedies.

          In  addition to any other remedies available to the
     Seller,  the  Seller  shall  have  the  right  to   seek

     This Agreement shall be binding upon and shall inure  to
the  benefit  of  the parties 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  Deed  shall  be  deemed   a
discharge  of all of the obligations of the Seller  hereunder
and   all   of   the  Seller's  representations,  warranties,
covenants  and agreements herein shall merge in the documents
and  agreements executed at the Closing and shall not survive
the Closing.
     21.  Limited Recourse.

that  it does not have and will not have any claims or causes

have  its  rights under this Agreement affected or diminished
