7.    REVIEW PERIOD.

      A.  PROPERTY DUE DILIGENCE SCHEDULE.  Buyer acknowledges that it has
completed and approved its local market reviews and studies.  Buyer shall
have until 5:00 p.m., eastern standard time, on December 15, 1997 (the
"Review Period"), time being of the essence, to complete its other reviews
and inspections of the Property, which reviews and inspections may include
an analysis of, but not limited to (i) the tenant leases, contracts, survey
and title documents affecting the Property, (ii) using non-invasive tests
and observations, the environmental and physical condition of the Property
and the Property's compliance with applicable law and (iii) the financial
condition of the Property.  On or before the end of the Review Period (time
being of the essence), Buyer either (x) will notify Sellers and Escrow
Agent in writing that Buyer elects to proceed with this transaction or (y)
will notify Sellers and Escrow Agent in writing that Buyer for any reason
whatsoever is not interested in purchasing the Property, whereupon in the
case of the failure to receive the notice in clause (x) on or before the
end of the Review Period or the receipt of the notice in clause (y) on or
before the end of the Review Period, the Escrow Agent shall immediately
return the Deposit to Buyer and except as otherwise provided herein neither
party shall have any further rights or obligations hereunder.  If Buyer
fails to deliver such notice to  Sellers prior to the expiration of the
Review Period time being of essence, then Buyer shall conclusively be
deemed to have terminated this Agreement and such failure to notify shall
have the same force and effect as if actual written notice to terminate
this Agreement were received by Sellers.  Buyer acknowledges that Sellers
have informed it of certain existing environmental conditions at the
Property, including without limitation the matters set forth in that
certain project report numbered T-1775 (the "Report"), dated June 30, 1997,
prepared by TETHYS Consultants, Inc., of Harrisburg Pennsylvania and
certain incidents of oil spillage, Buyer understands that, if Buyer elects
to proceed, Buyer shall assume and indemnify Sellers from and against all
loss, cost, damage, liability and expense, including, without limitation,
reasonable attorneys' fees and disbursements, arising from or relating to
the remediation (or a request for remediation by any governmental
authority) of the matters contained in such Report or with respect to such
oil spillage incidents (and any other environmental matters of which Buyer
has received written notice prior to the expiration of the Review Period or
any other environmental matters arising after the Closing), provided,
however, that if Sellers (as opposed to a third party) shall notify Buyer
of any such additional environmental matters later than December 12, 1997,
then the Review Period shall be extended until December 17, 1997 and the
Closing shall occur within four (4) business days thereafter, as designated
by Buyer (time being of the essence as to such dates), provided, however,
that either party may adjourn the Closing by notice to the other party for
not more than three (3) business days thereafter for any reason whatsoever,
time being of the essence as to Buyer's obligation to close by such date.
Buyer covenants that it will diligently perform and prosecute to completion
as soon as reasonably practicable following the Closing, at its sole cost
and expense, all work necessary to remedy the environmental conditions set
forth in the Report or in connection with the aforesaid oil spillage
incidents in accordance with applicable laws and regulations and to deliver
documentary evidence of such compliance to Sellers, in form reasonably
satisfactory to Sellers and Sellers' consultants. Buyer will commence its
due diligence promptly upon the receipt of a fully executed counterpart of
this Agreement and diligently work toward its completion.  Buyer hereby
waives any and all rights of contribution or other rights or remedies
against Sellers under the Comprehensive Environmental Response Compensation
and Liability Act or any other applicable environmental laws, rules or
regulations.  Buyer shall promptly notify Sellers if at any time during the
Review Period Buyer determines that Buyer is not interested in purchasing
Property.  If Buyer shall determine to not proceed with this transaction as
aforesaid, then upon written request of Sellers, Buyer shall promptly
provide Sellers with complete copies of all materials arising from Buyer's


<PAGE>


due diligence activities other than Buyer's internally generated analyses,
reports and memoranda.  Buyer agrees to indemnify and hold harmless Sellers
from and against all loss, cost, damage, expense or other liability
resulting from the conduct of Buyer's inspections, tests, investigations or
other due diligence, which indemnity shall survive the termination of this
Agreement.

      B.  INSPECTION.   Subject to the rights of tenants, employees
(including without limitation Tenant's employees and employees of Service
Providers (hereinafter defined)) and workers at the Property, Sellers shall
permit Buyer reasonable access to the Property and appropriate documents in
order to complete its due diligence inspections and reviews.  All
inspections and reviews will be conducted at reasonable times agreed upon
in advance by Sellers and Buyer, and at Sellers' election, Sellers may have
a representative present at such inspections and reviews.  Buyer will
conduct its inspections and reviews in such a manner so as not to cause any
damage, interruption, loss, cost or expense to, or claims against Sellers
or the Property, and Buyer will indemnify, defend and hold Sellers,
tenants, licensees, any of the respective direct or indirect partners of
Sellers, any of their respective advisors, shareholders, officers,
directors, trustees, beneficiaries, employees, agents and contractors and
the Property harmless from and against any such damage, interruption, loss,
cost or expense or claim.   During the Review Period, Buyer shall not
interview or discuss any matter with the union or non-union employees of
Sellers, the Service Providers or the property management company at the
Property (other than, upon prior notice to Sellers and the senior property
manager on site).  Additionally, during the Review Period  Buyer shall not
interview or discuss any matter with Tenants at the Property, provided,
however, that Buyer, with Sellers' representative present, may interview
MCI Telecommunications Corporation ("MCI"), Market Data, Entex Information
Services, Inc. and Compass Group USA, Inc. (such tenants are hereinafter
referred to as the "Major Tenants") regarding their respective tenancies
and the condition of the Property.  Sellers, upon reasonable prior notice,
shall reasonably cooperate with Buyer in conducting such interviews.  Buyer
shall make no invasive tests of the Property or any part thereof without
the Sellers' express written consent in each instance (which consent shall
not be unreasonably withheld).

      C.  CONFIDENTIALITY.  Except to the extent required by Buyer's legal
or other regulatory requirements, prior to Closing, Buyer (for itself and
its agents, legal or financial advisors, or prospective lenders) agrees to
keep all information obtained by or on behalf of Buyer with respect to the
Property, Sellers and any tenant leases or in connection with Buyer's due
diligence, in confidence, and not to disclose any such information to any
person, governmental entity or other entity other than Buyer or its agents,
legal or financial advisors, or prospective lenders, without Sellers' prior
written consent in each instance, it being understood that in cases where
disclosure is required by legal or regulatory requirements applicable to
Buyer, Buyer will describe the Property in general terms and not disclose
or reference information that could be used to identify the specific
location of the Property or the identity of the Sellers or any partner of
any Seller.  Buyer agrees that it shall not directly or indirectly engage
in or authorize any discussions with MCI, or any affiliate thereof,
regarding the purchase and/or sale of the Property or any portion thereof,
provided, however, that Buyer may interview MCI solely for the purposes
specified in paragraph B above in accordance therewith.  Sellers shall
refrain from negotiating with any other prospective buyer of all or any
portion of the Property (other than MCI) until November 26, 1997.

hereof, Buyer agrees to accept the Property "as is", in its present
condition, subject to reasonable use, wear, tear and natural deterioration
between the date hereof and the Closing Date, and further agrees that
Sellers shall not be liable for any latent or patent defects in the
Property or bound in any manner by guarantees, promises, projections,

            (ii)  Except as and solely to the extent otherwise provided
herein, Buyer hereby acknowledges and agrees that it shall not be entitled
to, and shall not, rely on Sellers, its agents, employees or
representatives, and Sellers hereby disclaim any representations or
warranties of any kind, either express or implied, either under common law,
by statute, or otherwise, as to (a) the quality, nature, adequacy or
physical condition of the Property including, but not limited to, any
structural elements, foundation, roof, appurtenances, access, landscaping,
parking facilities or any electrical, mechanical, heating, ventilating and

            (iii) Buyer acknowledges and agrees that Sellers have not made,

compliance of past owners and operators of the Property, with respect to
any past, present or future environmental laws or land use laws, rules,
regulations, orders or requirements.

            (iv)  Buyer acknowledges and agrees that by the expiration of
the Review Period, Buyer will have had an adequate opportunity to make such
legal, factual and other inquiries and investigations as Buyer deems
necessary, desirable or appropriate with respect to the Property.  Such
inquiries and investigations of Buyer shall be deemed to include an
environmental audit of the Property, an inspection of the physical
components and general condition of all portions of the Property, such
state of facts as an accurate survey and inspection would show, the present
and future zoning and land use ordinances, resolutions and regulations of
the city, town, county and state where the Property is located and the
value and marketability of the Property.

      E.    TENANT PURCHASE RIGHTS. Buyer acknowledges and understands that
its rights to purchase and hold title to the Property hereunder are subject
to (a) the continuing rights of MCI Telecommunications Corporation ("MCI")
and MCI International ("MCI International") to acquire certain portions of
the Property pursuant to the terms of their respective Leases at the
Property, and (b) New York Telephone's continuing right to acquire a
portion of Phase III pursuant to the terms of its lease at the Property.
Sellers represent to Buyer that they have previously delivered the right of
first refusal notices required by the terms of the MCI Lease.  Buyer
acknowledges that it has reviewed the terms of the MCI International Lease,
has determined that the transaction contemplated by this Agreement is not
subject to the purchase right contained therein and agrees not to raise an
objection to title on account of such purchase right.  If MCI shall
exercise its right to purchase any portion of the Property, then thereafter
neither Buyer nor Sellers shall have any further rights or obligations
hereunder (except for those matters which expressly survive the termination
hereof) and the Deposit immediately will be returned to Buyer. As a
condition precedent to Buyer's obligation to close on the Closing Date, REP
II shall deliver to Buyer and to Buyer's title insurance companies copies
of the notices which REP II caused to be delivered to MCI pursuant to MCI's
right of first refusal, which copies shall be certified as true and correct
by the general partners of REP II, which certification shall include the
date such notices were sent by REP II and the method(s) of delivery thereof
and that to the best of REP II's knowledge such notices substantially
comply with the right of first refusal notice requirements of the MCI
lease.  It shall be a condition of Closing that Buyer's Title Insurance
Company agree to omit or issue affirmative insurance that the instant
transaction is not subject to the MCI right of first refusal, provided
however that in no event shall any Seller pay any additional premium for
such omission or affirmative insurance.  In lieu of the Sellers' compliance
with the preceding two sentences, Sellers may deliver to Buyer a written
notice from MCI stating to the effect that MCI has received notice of the
instant transaction and is not exercising MCI's right of first refusal in
connection therewith, whereupon the provisions of the preceding two
sentences shall be deemed satisfied and Buyer shall raise no objection to
title based upon the MCI right of first refusal.

      F.    SURVIVAL.   The provisions of this Paragraph 7 shall survive
the termination of this Agreement and the Closing.

8.    APPORTIONMENTS AND PAYMENTS.

      A.    The following are to be apportioned between Sellers and Buyer
as of the Closing Date and the net amount thereof shall either be paid by
Buyer to Sellers (with such amount to be paid to Sellers by Buyer's good
certified or official bank check, payable to the order of Sellers, or wire
transfer of immediately available funds), or credited by Sellers against
the Balance of the Purchase Price, as the case may be, at the Closing:

            (i)    real property taxes;

             (ii)       water charges;

             (iii)      sewer taxes and rents;

             (iv)  annual permit, license and inspection fees, if any, on
the basis of the fiscal year for which levied, if rights thereunder with
respect thereto are transferable to Buyer;

             (v)        fuel, steam and all other utilities;

             (vi)  fixed, additional and escalation rents (including,
without limitation, common area maintenance payments) payable under any
Leases (as hereinafter defined) between Sellers and space tenants
(collectively the "Rent"), if, as and when collected;

            (vii) interest and permitted administrative charges, if any, on
tenants' security deposits;

             (viii) supplies on hand in the Property in unopened cartons,
at Sellers' cost;

             (ix) wages, vacation pay, pension and welfare benefits and
other fringe benefits of all persons employed at the Property;

            (x) amounts payable under any Contracts (as hereinafter
defined) assumed by Buyer; and

             (xi) all other items customarily apportioned in connection
with similar conveyances in the County of Westchester, State of New York.

      B.    If the Closing Date shall occur before the real property taxes,
water rates and charges and sewer taxes and rents are finally fixed, the
apportionments thereof made at the Closing shall be upon the basis of the
tax or water rates for the preceding year applied to the latest assessed
valuation, but after the real property taxes, water rates and charges and
sewer taxes and rents are finally fixed, Sellers and Buyer shall make a
recalculation of the apportionment of same, and Sellers or Buyer, as the
case may be, shall make an appropriate payment to the other based on such
recalculation.

      C.    Sellers shall arrange for a final reading of all master utility
meters (covering steam, gas, electricity and water and the derivative sewer
charges based on meters).  Sellers and Buyer shall jointly execute a letter
to each of such utility companies advising such utility companies of the
termination of Sellers' responsibility for such charges for utilities
furnished to the Property from and after the Closing Date.  If a bill is
obtained from any of such utility companies before the Closing Date,
Sellers shall pay such bill on or before the Closing and deliver proof of
payment thereof to Buyer.  If such bill shall not have been obtained before
the Closing, Sellers shall pay all such utility, water and sewer charges as
evidenced by the last bill or bills relating to the period prior to the
Closing Date and Buyer shall pay all such utility charges relating to the
period after the Closing Date.  Any bill which shall be rendered which
shall cover a period both before and after the Closing Date shall be
apportioned between Buyer and Sellers as of the Closing Date.  An amount
equal to all security deposits, prepayments or credits accrued with Service


<PAGE>


Providers under the assigned Contracts, or with utilities, water and sewer
companies or other parties relating to the Property shall be paid to
Sellers by Buyer at the Closing, provided that if such security deposits,
prepayments or credits shall not be transferable to Buyer, Buyer shall
cooperate with Sellers' efforts to collect and enjoy such amounts.

      D.    The amount of any unpaid taxes, assessments, water rates and
charges and sewer taxes and rents which Sellers are obligated to pay and
discharge, with interest and penalties thereon to the second business day
after the Closing Date, may, at the option of Sellers, be allowed to Buyer
out of the Balance of the Purchase Price, provided that official bills
therefor, with interest and penalties thereon, are furnished by Sellers at
the Closing.  If there are any other liens or encumbrances which Sellers
are obligated to pay and discharge, Sellers may use any remaining portion
of the Balance of the Purchase Price to satisfy the same, provided that
Sellers shall deliver to Buyer, at the Closing, instruments in recordable
form sufficient to satisfy such liens and encumbrances of record, together
with a check for the cost of recording or filing said instruments.  Buyer,
if request is made at least three (3) business days prior to the Closing,
agrees to provide Sellers at the Closing, with separate certified and/or
official bank checks, payable as directed by Sellers, to facilitate the
satisfaction of any of the aforesaid taxes, assessments, water rates and
charges, sewer taxes and rents, liens and encumbrances.

      E.    If Sellers receive Rent payments from tenants at the Property
after the Closing Date which are for any period subsequent to the Closing
Date, Sellers shall remit to Buyer the amount of such Rent.  If any past-
due Rent is owing as of the Closing Date, or if any Rent for the period
prior to the Closing Date shall have accrued although the same is not then
due and payable, Buyer agrees that the first monies received by Buyer from
tenants owing such past-due or accrued Rent, in an amount not exceeding one
month's Rent shall be received by Buyer, as trustee for Sellers, on account
or in payment of, such past-due or accrued Rent, and Buyer shall forthwith
remit to Sellers the amount of such past-due or accrued Rent out of such
first monies received by Buyer (the "General Rule").  Buyer acknowledges
that MCI International currently owes Sellers approximately $141,691.15 for
certain items of additional rental under its Lease and for certain sidewalk
repair work performed at the Property.  If Sellers shall not have been paid
such amounts from MCI International prior to Closing, then Buyer shall
forthwith remit to Sellers, out of the first monies received by Buyer from
MCI International an amount equal to the lesser of (i) $141,691.15 or (ii)
the amount of one month's fixed and escalation Rent under the MCI
International Lease, it being understood that Sellers shall not receive
monies under the General Rule in payment of said $141,691.15 by MCI
International to the extent that Sellers have been paid monies on account
of such $141,691.15 under this sentence.  Buyer agrees that Sellers shall
be entitled to retain any monies paid by J.B. Hanauer & Co. ("Hanauer") in
connection with the release of such tenant from its obligations under its
Lease or otherwise.   Nothing herein contained shall preclude Sellers from
asserting separate and independent claims against such tenants, but only if
each such claim to be asserted exceeds $5,000.00, including, but not
limited to, the institution of such actions as Sellers shall deem necessary
or advisable for the purpose of collecting such past due rentals, the right
(but not the obligation) to do any of which is hereby reserved by Sellers.
Buyer shall cooperate with Sellers to collect any Rents (including, without
limitation, escalation additional rents) owing to Sellers in accordance
herewith.



<PAGE>


      F.    Subject to the provisions of subparagraph E above, to the
extent that Rent cannot be determined on the Closing Date, or is collected
after the Closing Date for any period prior thereto, the amount of such
Rent for the period ending on the Closing Date, and all accountings showing
the calculations thereof, shall be paid and furnished to Sellers by Buyer
if, as and when received after the Closing Date.  The portion of the Rent
consisting of additional rent and escalation rent shall be apportioned on a
calendar year or fiscal year basis (depending upon which is appropriate
under each Lease) so that the amount thereof under any of the Leases to
which Sellers shall be entitled shall be an amount which bears the same
ratio to the total additional and escalation rents due thereunder for the
current period as the number of days in said period which shall have
elapsed prior to the Closing Date bears to the total number of days in said
period. In furtherance thereof, Buyer shall pay to Sellers all escalation
additional Rent (i.e., tax, operating expense and other escalation
additional Rent) payable under the Leases which relate to the period from
January 1, 1997 through the actual Closing Date as and when collected by
Buyer.  Escalation additional Rent for calendar year 1997 shall be billed
by Buyer on or about April 1, 1998, and Buyer shall pay to Sellers any
portion thereof to which Sellers are entitled as aforesaid, as and when
collected by Buyer.  Sellers agree to make available for Buyer's
examination, all records, statements and accounts bearing on or relating to
Rent and, on the Closing Date, to furnish Buyer with a comprehensive and
complete statement of prepaid Rent and uncollected Rent.  Subsequent to the
Closing and until all apportionments shall have been finally determined,
Buyer agrees to make available for Sellers' examination, all records,
statements and accounts bearing on or relating to Rent.  Any prepaid Rents
received by Sellers on or before the Closing Date covering any period of
time subsequent thereto shall be credited to Buyer at the Closing.

      G.    At the Closing, Sellers shall deliver to Buyer a good certified
or official bank check, payable to the order of Buyer (or grant Buyer a
credit against the Balance of the Purchase Price due at Closing), in the
aggregate amount of any security deposits held under any Leases between
Sellers and space tenants, together with any accrued interest earned
thereon and credited to Sellers' security deposit account (adjusted
pursuant to Paragraph 8(A) hereof).  Buyer shall execute a receipt for the
amount of all security deposits so paid over.  If any tenant of the
Property having a security deposit is in default under the terms of its
Lease and either (x) notices of default and termination of such tenant's
Lease shall have been duly given or (y) such estoppel certificate executed
by the tenant acknowledges that the security deposit held by the landlord
under the Lease has been reduced by reason of the tenant's default or fails
to state a claim that the landlord is in default of such tenant's Lease by
reason of such reduction in the security deposit, Sellers may retain so
much of the security deposited by such tenant and the interest accrued
thereon as shall be sufficient to cover Sellers' loss by reason of such
tenant's default.

      H.    At the Closing, Sellers shall pay their own counsel fees, deed
stamps, transfer taxes and such other closing costs as are customarily paid
by a seller and Sellers shall execute and deliver any appropriate return or
form as may be required in connection therewith.  Buyer shall pay its
counsel fees, title insurance and survey costs, sales taxes (if any) and
such other closing costs as are customarily paid by a buyer and execute and
deliver any appropriate return or form as may be required in connection
therewith. In addition, any costs relating to Buyer's due diligence,
including, without limitation, those relating to appraisers, inspectors,
auditors and environmental or engineering consultants, shall be Buyer's
sole responsibility. Sellers shall have the option to grant to Buyer a
credit against the Balance of the Purchase Price, at the Closing, in an
amount equal to the amount of any deed stamps and transfer taxes payable by
Sellers.  If such adjustment is made by Sellers, Buyer agrees to pay the
amount of such deed stamps and transfer taxes.


<PAGE>


      I.    Fuel oil, if any, owned by Sellers and on the Property on the
date as of which adjustments shall be made, shall be adjusted at the cost
price thereof to Sellers, as reflected in Sellers's last bill, plus taxes
paid thereon.  The amount of fuel oil is to be estimated in writing by the
fuel company currently supplying fuel to the Property, as of a date which
is not more than three (3) business days prior to the Closing Date.

      J.    If, on the Closing Date, the Property or any part thereof shall
be affected by any assessments which are payable in installments, then
installments payable prior to the Closing Date shall be paid by Sellers
(subject to apportionment as provided for herein), and installments payable
after the Closing Date shall be paid by Buyer (subject to apportionment as
provided herein).  Any such installments payable by Buyer shall not be
objections to title whether or not the same constitute liens on the Closing
Date.

      K.    Sellers have instituted prior to the Closing Date tax reduction
proceedings seeking to reduce the assessed valuation of the Property (a
"tax reduction proceeding") for certain periods before and after the
Closing Date.  Subsequent to the Closing, Sellers shall be permitted to
continue such tax reduction proceedings, whether in the name of Sellers or
Buyer.  Any refund of taxes which results from a tax reduction proceeding
commenced by Sellers ("refund") shall be the sole property of Sellers,
except that Buyer shall be entitled to that portion of the refund (after
deduction from the full refund of all of Sellers' expenses incurred in
connection therewith, including without limitation attorneys' fees and
expenses) which is refundable to tenants under the Leases, and that portion
of such refund which relates to the period subsequent to the Closing.
Sellers shall have the right to settle any tax reduction proceeding without
Buyer's consent, except to the extent Buyer will be bound by any settlement
for any tax year following the Closing and for any tax reduction proceeding
relating solely to the tax year in which the Closing occurs, for which
Buyer's prior written consent shall be required, which consent Buyer agrees
not to unreasonably withhold or delay.  Buyer shall execute and deliver any
documents that may be reasonably required by Sellers in connection with
such tax reduction proceeding and any recovery had thereunder, all without
charge or expense to Sellers.

      L.    The parties hereto agree that any errors or omissions in
computing apportionments at the Closing shall be corrected promptly after
their discovery.  In furtherance thereof, the parties agree to recalculate
apportionments and make appropriate payments to each other on or about the
ninetieth (90) day following the Closing.

      M.    The parties hereto agree that Buyer's attorneys shall be "the
real estate reporting person" with respect to this transaction who is
responsible for the completion of form 1099S or such other successor form
as may be prescribed by the Internal Revenue Service and for fulfilling all
of the obligations and requirements of Section 6045(e) of the Internal
Revenue Code of 1986, as amended.

      N.    Sellers shall be responsible for paying $771,450 on account of
tenant improvement work in connection with Compass Group USA, Inc. Lease,
and $13,617 representing brokerage commission in connection with the
failure of MCI to exercise a right of termination in the MCI Lease.  In
addition, Sellers shall be responsible for all brokerage commissions which
were due and payable or which accrued prior to the date of Closing, it
being understood by way of example that if a lease is signed prior to the
Closing and the brokerage agreement provides for the payment of a $20,000
brokerage commission in two instalments of $10,000, the first instalment
payable before the Closing and the second instalment payable after the
Closing, the Sellers shall nevertheless be responsible for the payment of
both $10,000 instalments, unless the second instalment relates to
circumstances (such as the tenant's failure to terminate or exercise of an


<PAGE>


expansion or renewal right) which by their nature will not occur until
after the Closing in which latter case the Sellers shall pay the first
$10,000 instalment and the Buyer shall pay the second $10,000 instalment.
Notwithstanding the foregoing example, in all cases where a brokerage
commission is claimed with respect to a current or future Lease and the
right to earn the commission is or may be affected by events that occur or
fail to occur subsequent to the Closing, Buyer shall be responsible for all
such commissions.

      O.    The provisions of this Paragraph 8 shall survive the Closing
Date.

9.    CLOSING DOCUMENTS.

          A.      At the Closing, and upon payment by Buyer of the Balance
of the Purchase Price (plus any other sums which Buyer has agreed herein to
pay to Sellers at the Closing, but less any credits to which Buyer may be
entitled to hereunder), each Seller shall deliver to Buyer the following
with respect to the portion of the Property owned by such Seller:

            (i)   A bargain and sale deed (without covenants) from each
Seller (collectively, the "Deeds"), in proper statutory form for recording,
which shall be duly executed and acknowledged so as to convey to Buyer
title to that portion of the Property owned by each Seller, subject to the
Permitted Exceptions.  Specifically, subject to and in accordance with the
terms hereof, REP I shall convey title, to that portion of the Property
described on Exhibit "A-1" annexed hereto, REP II shall convey title to
that portion of the Property described on Exhibit "A-2" annexed hereto and
REP III shall convey title to that portion of the Property described on
Exhibit "A-3" annexed hereto;

            (ii)  An assignment and assumption of the Leases, in the form
attached hereto as Exhibit "C";

            (iii) An assignment and assumption of Contracts in the form
attached hereto as Exhibit "D".  Sellers, at Buyer's written request, shall
terminate by notice given at the Closing any Contracts (other than all
applicable brokerage or commission agreements with respect to tenants or
Leases at the Property, none of which shall be terminable by Buyer) which
Buyer elects not to assume, it being understood that Buyer shall be
responsible for and indemnify Sellers against any amounts due under such
terminated Contracts for the period subsequent to the Closing through the
effective date of termination, it being further understood that Buyer shall
notify Sellers as to which Contracts it elects not to assume by the Closing
Date;

            (iv)  Notices executed by Sellers addressed to all tenants in
the Buildings, advising them of the within sale, the assignment of their
respective Lease security deposit (including interest) (if held by such
Seller) and the assumption by Buyer of the obligations as landlord
thereunder, directing them to send Rent to Buyer or Buyer's managing agent,
and containing such other information as may be required in order to
relieve such Sellers from any liability to such tenants with respect to the
security deposits delivered to Buyer, which notices Buyer shall mail, at
Buyer's sole cost and expense, to each tenant by certified mail, return
receipt requested;



<PAGE>


            (v)   As a condition to Closing, Sellers shall deliver executed
estoppel certificates, substantially in the form of the estoppel
certificate attached hereto as Exhibit "E" or in the form required by the
applicable lease with no material omissions therefrom or material changes
thereto or new provisions or statements added thereto, any of which are
materially adverse to the rights or interests of the landlord under the
lease of the tenant giving such certificate, from the Major Tenants
(including MCI and MCI International and their affiliates that have a Lease
to occupy space at the Property ) and from tenants occupying not less than
fifty percent (50%) of the balance of the leased space at the Property;
provided, however, that Sellers shall request estoppel certificates from
all tenants in the Building.  In the event an estoppel certificate
delivered by a tenant does not conform to the form of the estoppel
certificate attached hereto and if such non-conforming matter can be
remedied by the performance of work or the payment of money, Sellers shall
have the right but not the obligation to cure the non-conforming matter set
forth in such estoppel certificate, by either performing or causing to be
performed the work, paying the money, or by granting Buyer a credit against
the Purchase Price in an amount reasonably necessary to perform such work,
as reasonably determined by the parties.  Additionally, if Sellers shall be
unable to deliver an estoppel certificate for any tenant of the Building by
the Closing Date other than the Major Tenants, for which Sellers shall be
required to deliver an estoppel certificate, then Sellers shall have the
right but not the obligation to deliver to Buyer, in substitution for such
estoppel certificate, a certificate from Sellers (a "Sellers'
Certificate"), certifying as to the matters set forth in the form of the
estoppel certificate attached hereto as Exhibit "E" which shall survive the
Closing until November 15, 1998; provided, however, that if Sellers shall
deliver a partially completed estoppel certificate from a particular
tenant, then such Sellers' Certificate shall cover only those matters set
forth in the estoppel certificate which were not confirmed by the
respective tenant. If Sellers deliver an estoppel certificate for a
required tenant subsequent to the Closing Date, then such Sellers'
Certificate shall be deemed canceled to the extent of the matters confirmed
in such estoppel certificate, provided, however, that if the required
estoppel certificate shall have been fully completed, then the Sellers'
Certificate with respect thereto shall be canceled in full;

            (vi)  Original or certified copies of all Leases, amendments
and other documents relating thereto, rent records and related documents in
the possession or under the control of Sellers (which documents may be
delivered at the Property).  Such records shall include a schedule of all
cash security deposits, including any interest thereon, held by Sellers on
the Closing Date under the Leases together with appropriate instruments of
transfer or assignment with respect to any lease securities which are other
than cash and a schedule updating the Lease Schedule and setting forth all
arrears in rents and all prepayments of rents;

                  (vii)  Such affidavits and indemnities as the Title
Company may reasonably require in order to omit from its title insurance
policy all exceptions for (a) judgments, bankruptcies or other returns
against persons or entities whose names are the same as or similar to
Sellers' names; (b) parties in possession (other than tenants pursuant to
the Leases and other occupants under the Contracts); and (c) mechanics'
liens;

                  (viii) Sellers shall make all tenant files and records
including without limitation all tenant correspondence and billing for
escalations and files and records for the Buildings available to Buyer for
copying, which obligation shall survive the Closing;



<PAGE>


                  (ix)   Original (or photocopies, if originals are
unavailable to Sellers) of all site plans, surveys, soil and substrata
studies, architectural drawings, plans and specifications, engineering
plans and studies, floor plans, landscape plans and other plans or studies
of any kind in the possession or under the control of Sellers that relate
(a) to the Land, the Buildings, including without limitation as-built plans
for tenant improvements, or (b) otherwise to the Property.  Sellers shall
also deliver (i) original (or photocopies, if originals are unavailable to
Sellers) of all then effective assignable guaranties and warranties made by
any person for the benefit of Sellers and in the possession or under the
control of Sellers, with respect to the Property or any of its components,
together with an instrument in form and substance reasonably satisfactory
to Buyer assigning the same to Buyer, and (ii) all certificates, licenses,
permits, authorizations and approvals issued for or with respect to the
Property by governmental and quasi-governmental authorities having
jurisdiction, except that photocopies may by substituted if the originals
are posted at the Property.

                  (x)   All keys in Sellers' possession to all entrance
doors to, and any equipment and utility rooms located in, the Property
(appropriately tagged for identification); and

                  (xi)  An executed Affidavit of Non-Foreign Status,
certifying that each Seller is not a "foreign person" pursuant to Section
1445 of the Internal Revenue Code;

      B.    At the Closing, Buyer shall deliver to Sellers a duly executed
and acknowledged agreement in form and substance reasonably satisfactory to
Sellers whereby Buyer shall (i) assume all of Sellers' obligations under
the Leases (arising from and after the Closing), and (ii) agree to
indemnify Sellers against, and hold Sellers harmless from, any liability,
damages, claims, losses, costs and expenses (including attorneys' fees)
arising from or relating to (x) the Leases or the obligations or
responsibilities of the landlord thereunder with respect only to the period
subsequent to the Closing and the security deposits delivered under such
Leases (but only to the extent same have been delivered to Buyer) and (y)
the Pertinent Matters.

      C.    The parties acknowledge and agree that no portion of the
Purchase Price is for or allocated to any personal property (if any)
located at the Property.  However, if any governmental body deems any part
of the Purchase Price to have been paid for any personal property
transferred hereunder, then Buyer shall pay all such sales tax so payable,
which payment shall be made at the Closing.  The provisions of this
subparagraph shall survive the Closing.

10.   Title Insurance.

          A.     Buyer shall order from a reputable title insurance company
which is licensed to do business in the States of Connecticut and New York
(the "Title Company"), within five (5) days after the execution of this
Agreement, time being of the essence, a title report with respect to the
Property and request the Title Company to deliver to the Sellers a copy
thereof promptly upon receipt of the same, but, in all events, not later
than the expiration of the Review Period, time being of essence.  If such
title report discloses title defects or exceptions to title which are not
included within the Permitted Exceptions and if, by reason of such title
defects or exceptions, the Sellers shall be unable to convey title to the
Property in accordance with the provisions of this Agreement, then the
Sellers shall have the right, but not the obligation, to attempt to cause
the Title Company to omit such defects or exceptions from the title
insurance policy to be issued to the Buyer and, for such purpose, the
Sellers shall be entitled to one or more adjournments of the Closing for a
period not exceeding sixty (60) days in the aggregate.  If the Sellers
refuse or are unable to eliminate any such title defects or exceptions and
convey title to the Property in accordance with the terms of this Agreement


<PAGE>


by the Closing, as the same may be adjourned as aforesaid, then the Buyer,
as its sole and exclusive remedy, may elect by written notice to the
Sellers to either (i) reject title to the Property and terminate this
Agreement, or (ii) accept title to the Property subject to such defects or
exceptions without any abatement of the Purchase Price or liability on the
part of the Sellers.  If Buyer shall reject title under subsection (i)
above, then neither party shall have any liability whatsoever to the other
hereunder except that Buyer shall be entitled to a prompt refund of the
Deposit and the net cost of any title commitments and survey charges not
exceeding $15,000.00 in the aggregate. The existence of any condition to
which Buyer agrees to take subject under this Agreement shall not be deemed
or construed to render Sellers' title unmarketable, and notwithstanding
that such conditions may render title unmarketable, Buyer shall not have
the right to reject title by reason thereof, the Purchase Price shall not
in any respect be reduced, and Buyer shall not be entitled to damages
therefor.  Anything contained in this subparagraph to the contrary
notwithstanding, the Buyer shall accept such title to the Property as the
Title Company shall be willing to insure, subject only to the Permitted
Exceptions.   Notwithstanding anything to the contrary contained herein,
Sellers shall be obligated to remove any title exceptions for mortgages
made by Sellers, tax liens against Sellers or imposed upon the Property,
judgment liens against Sellers, or mechanics liens for work performed at
the request of Sellers and which in each case may be removed by the payment
of a liquidated sum and any title exception (other than the Permitted
Exceptions) created by Sellers' voluntary acts after the date hereof.

      B.    If a search of the title discloses judgments, bankruptcies or
other returns entered against any other person or entity having a name the
same as or similar to that of Sellers, Sellers shall, at the Closing,
deliver to Buyer affidavits showing that such judgments, bankruptcies or
other returns are not against Sellers.

      C.    Except as provided in paragraph A above, the Sellers do not
agree to undertake, and nothing herein contained shall be construed to
require Sellers to bring any action or proceeding or otherwise to incur any
expense whatsoever to render title to the Property either acceptable to
Buyer, insurable, or to be in accordance with the provisions of this
Agreement.

      D.    Except as provided in paragraph A above, the premium for
Buyer's title insurance policy to be issued by the Title Company pursuant
to the Commitment, and all related charges and survey costs incurred in
connection with the Commitment or such policy, shall be paid by Buyer.

11.   THE LEASES.

      A.     Buyer acknowledges that Buyer has examined the Leases set
forth on the lease schedule (the "Lease Schedule") annexed hereto as
Exhibit "F".  Sellers represent and warrant that, except as disclosed to
Buyer prior to the end of the Review Period, to the Sellers' actual
knowledge, (i) the Leases set forth on such Lease Schedule constitute all
of the agreements (other than any subleases and the Contracts) which relate
to, affect the occupancy of, or create and/or affect the rights to the
occupancy of, the Property or any portion thereof, and all amendments,
renewals, extensions and modifications thereof, (ii) except as set forth in
the Leases (and any subleases and Contracts), no person or firm has any
right to occupy any portion of the Property, (iii) all of the Leases are in
full force and effect and other than as set forth on the Lease Schedule,
none of them have been modified, amended or extended and no renewal or
expansion options have been granted to tenants except as specifically set
forth in the Leases, (iv) except for MCI, MCI International and New York
Telephone, no tenant has an option to purchase the Property or any part
thereof, (v) except as set forth therein, the rents set forth on the Lease
Schedule are being collected on a current basis and there are no arrearages


<PAGE>


in excess of one month, (vi) except as set forth in the Leases, no tenant
is entitled to rental concessions or abatements for any period subsequent
to the Closing Date, (vii) Sellers have not sent written notice to any
tenant of the Property claiming that such tenant is in default, which
default remains uncured, other than the unpaid Rent sums set forth on the
Lease Schedule, (viii) no action or proceeding instituted against Sellers
by any tenant of the Property is currently pending in any court, except
with respect to claims involving personal injury or property damage which
are covered by insurance and described on Exhibit "G", (ix) there are no
security deposits or prepaid rent in the nature of a security deposit other
than those set forth in the Lease Schedule or the Leases, (x) no rent has
been paid more than thirty (30) days in advance under any of the Leases,
(xi) all tenant improvement work required to be completed or paid for by
Sellers has been or prior to the Closing Date will be completed or paid
for, as the case may be, and (xii) except as set forth in the Leases and on
Exhibits F (Lease Schedules) and H (Contracts), there are no unpaid leasing
commissions or any liability therefor arising from options to expand or
renew contained in any of the Leases.

      B.    Except as is otherwise provided herein, Sellers agree that
Sellers will not make any modifications of the Leases which affect the
period subsequent to the Closing without the prior written consent of
Buyer, which consent Buyer agrees not to unreasonably withhold or delay.
Buyer acknowledges that Hanauer previously assigned its Lease to American
Progressive Life and Health Insurance Company of N.Y. by Assignment and
Assumption of Lease Agreement, dated September 29, 1997.  By Consent to
Assignment, dated October 8, 1997, REP II consented to such assignment.
Buyer agrees that REP II shall have the right to release  Hanauer from its
obligations under its Lease and the aforesaid Assignment and Consent and
REP II may receive any amounts payable in connection therewith.

      C.    The right and privilege is reserved to Sellers to institute
termination and eviction proceedings against any tenant prior to the
Closing based upon such tenant's failure to observe or perform any of its
obligations pursuant to its Lease, but notice thereof shall be given to the
attorneys for Buyer.  Sellers do not guarantee or undertake that any tenant
of the Property will be in occupancy on the Closing or that any of the
Leases will be in force or effect on the Closing.  Buyer agrees that the
vacating of any portion of the Property by any tenant, or the removal of
any tenant by eviction proceedings, or the termination of any of the
tenants' occupancies, by reason of defaults arising under the Lease or
otherwise, prior to the Closing, shall not give rise to any claim on the
part of Buyer or affect the obligations of Buyer hereunder in any manner
whatsoever.

      D.    If any of the rentable space in the Property is currently
vacant or becomes vacant between the date of this Agreement and the
Closing, the same shall not be relet, nor shall any extension or renewal of
any lease be made, nor shall any modification of the terms of any lease or
rental agreement be made (other than the Weston Insurance Brokerage, Inc.
Amendment of Lease) and Hanauer release, except with the prior written
consent of Buyer, which shall not be unreasonably withheld or delayed.

12.   ACCEPTANCE OF DEED; REPRESENTATIONS AND WARRANTIES.



      A.    The acceptance of the Deeds by Buyer shall be deemed to be an
acknowledgment by Buyer that Sellers have fully performed, discharged and
complied with all of Sellers' obligations, representations, warranties,
covenants and agreements hereunder, that Sellers are discharged therefrom
and that Sellers shall have no further liability with respect thereto,
except for (i) the post-closing adjustments (if any) required hereunder,
and (ii) those, if any, which are herein specifically stated to survive the
Closing.



<PAGE>


      B.    Sellers and Buyer represent and warrant to each other that the
execution, delivery and performance of this Agreement have been duly
authorized and, except as otherwise provided herein, no other action or
approval is required in order to enable each respective party to consummate
the transaction contemplated by this Agreement.

      C.    Each Seller as to its portion of the Property to its actual
knowledge hereby represents and warrants to Buyer that:

            (i)   Such Seller has full right, power and authority in
accordance with law to sell and convey its interest in the Property to
Buyer as provided herein, subject to the purchase rights set forth in
Paragraph 7 above.

            (ii)  Sellers know of no pending or threatened actions or
proceedings regarding condemnation of the Property or any part thereof.

            (iii) Except as set forth on Exhibit "G" annexed hereto,
pending tax certiorari proceedings, matters in the Report and the oil
spillage incidents referenced in Paragraph 7(A), there is no action, suit,
litigation, claim, administrative or governmental or quasi-governmental
investigation or proceeding pending against or relating to the Property.

            (iv)  Exhibit "H" annexed hereto lists all service,
maintenance, supply and management contracts (collectively, the
"Contracts") known to Sellers affecting the Property, and the information
set forth therein is accurate and complete as of the date hereof.  Except
as otherwise specifically set forth in Exhibit "H" or elsewhere in this
Agreement (1) all of the Contracts are in full force and effect and none of
them have been modified, amended or extended, (2) Sellers have not sent
written notice to, or received written notice from, any management company,
maintenance or service provider (collectively, the "Service Providers")
claiming default under any Contracts,  and (3) no action or proceeding
instituted by Sellers against any Service Providers or by any Service
Providers against Sellers is currently pending in any court.

            (v)   There are no employees of Seller employed at the Property
and no union contracts affecting the Property except as noted on Exhibit H
(Contracts).

            (vi)  As of the Closing Date, there will be no outstanding
rights of first refusal, rights of first offer, options or similar rights
to purchase all or any portion of the Property other than the respective
MCI, MCI International and New York Telephone's continuing options to
purchase a portion of the Property or portions thereof as set forth in its
lease, copies of which will be delivered to Buyer for its review during the
Review Period.

During the Review Period Sellers may notify Buyer of any matter that is the
subject of any Seller's representation or warranty (including, without
limitation, any matter related to brokerage or other Contracts and the
Leases), which noticed matter will be deemed an exception to such
representation or warranty and shall be deemed included in the appropriate
obligations to be assumed by Buyer, provided, however, that if Sellers (as
opposed to a third party) shall notify Buyer of any such additional matters
later than December 12, 1997, then the Review Period shall be extended
until December 17, 1997, and the Closing shall occur within four (4)
business days thereafter, as designated by Buyer (time being of the essence
as to such dates), provided, however, that either party may adjourn the
Closing by notice to the other party for not more than three (3) business
days thereafter for any reason whatsoever, time being of the essence as to
Buyer's obligation to close by such date



<PAGE>


      D.    Anything to the contrary contained in this Agreement
notwithstanding, the covenants, representations and warranties of each
Seller shall survive until November 15, 1998, whereupon all covenants,
representations and warranties of Sellers shall be deemed fully observed,
paid and performed, and Buyer shall have no further rights or remedies with
respect thereto, except for the breach of those covenants, representations
and warranties that are the subject of (x) a notice given on or before
November 15, 1998, from Buyer to Sellers in writing that describes with
specificity the nature of the breach and the damages arising therefrom, and
(y) litigation of the breach described in such notice that is duly
commenced on or before the fifteenth (15th) day) after the notice is given
pursuant to clause (x) and at all times prosecuted diligently thereafter,
as to which notice and litigation dates time shall be of the essence.

      E.    For purposes of this Agreement, all references to "knows,"
"known" or "knowledge" of any of the Sellers shall mean the actual
knowledge without further inquiry as of the date of the relevant
representation or warranty of the following individuals:

                  For REP I:  Douglas Welker or Thomas J. Collins,
                  For REP II: Douglas Welker or Thomas J. Collins, and
                  For REP III:      Thomas J. Collins,

it being understood that each Seller currently relies upon the knowledge of
such individuals as representatives of the general partner of each Seller
who are generally familiar with major current matters affecting the
Property owned by such Seller (other than matters known to the property
manager, the property engineer or other specialists entrusted with specific
matters or responsibilities concerning the Property, to the extent that (x)
the knowledge of such specialists has not been imparted to Messrs. Welker
or Collins in writing and (y) such writing is not disclosed to the Buyer
prior to the end of the Review Period).

13.   BROKER

      Buyer represents and warrants to Sellers that Buyer has had no
dealings with respect to this transaction with any real estate broker, firm
or salesman, or any other person or corporation, except Richard Ellis LLC,
Inc. (the "Broker"), and Sellers agree to pay the brokerage commission due
to the Broker in accordance with the terms of a separate written agreement
with said Broker.  Buyer agrees to indemnify Sellers against, and defend
Sellers and save Sellers harmless from and against any and all claims, and
Sellers' reasonable expenses related thereto (including attorneys' fees),
for brokerage commissions, fees or other compensation by any person, firm
or corporation (other than the Broker) who shall allege to have acted in
this transaction with Buyer or dealt with Buyer in connection herewith.
Sellers agree to indemnify Buyer against, and defend Buyer and save Buyer
harmless from any and all claims, and Buyer's reasonable expenses related
thereto (including reasonable attorneys' fees), for brokerage commissions,
fees or other compensation by any person, firm or corporation who shall
allege to have acted in this transaction with Sellers or dealt with Sellers
in connection herewith.  The provisions of this Paragraph shall survive the
Closing and any termination of this Agreement.

14.   CONDEMNATION AND DESTRUCTION.

      A.    If, prior to the Closing Date, all or any significant portion
of the Property is taken by eminent domain or is the subject of a pending
taking which has not been consummated (collectively, a "Taking"), Sellers
shall notify Buyer of such fact and Buyer shall have the option to
terminate this Agreement upon notice to Sellers given not later than ten
(10) business days after receipt of Sellers's notice, time being of the
essence.  If this Agreement is terminated, as aforesaid, then the Deposit


<PAGE>


shall be returned to Buyer, and thereupon neither party shall have any
further rights or obligations to the other hereunder except such
obligations as survive termination of this Agreement.  If Buyer elects not
to terminate this Agreement as aforesaid, or if an "insignificant portion"
(i.e., any Taking which does not materially interfere with access to the
Property and does not serve to decrease in any material respect the size of
any of the Buildings) of the Property is taken by eminent domain, there
shall be no abatement of the Purchase Price, but Sellers shall assign and
turn over at the Closing, and Buyer shall be entitled to receive and keep,
all awards for such taking by eminent domain.

      B.    If, prior to the Closing, a material part of any of the
Buildings is destroyed or damaged by fire or other casualty ("material"
being deemed to be any destruction greater than "immaterial", as defined
below, or permitting Tenants paying Rents of more than ten percent (10%) of
the aggregate Rents of the Property to terminate their leases), Sellers
shall notify Buyer of such fact and Buyer shall have the option to
terminate this Agreement upon notice to Sellers given not later than twenty
(20) days after receipt of Sellers's notice.  If this Agreement is
terminated as aforesaid, then the Deposit shall be returned to Buyer, and
thereupon neither party shall have any further rights or obligations to the
other hereunder except such obligations as survive the termination of this
Agreement.  If Buyer elects not to terminate this Agreement as aforesaid,
or if there is damage to or destruction of an "immaterial" part of any of
the Buildings by fire or other casualty, then Sellers shall assign and turn
over, and Buyer shall be entitled to receive and keep, all insurance
proceeds paid or to be paid, and relating to the damage to the Property
caused by such casualty (the "Proceeds"), which remain after payment or
reimbursement is made for the work (if any) performed by Sellers in
connection with such casualty together with a check for the deductible
amount under Sellers' insurance policy (if any), without further abatement
of the Purchase Price, provided, however, that in no event shall Sellers be
obligated to restore any portion of the Property that is damaged by
casualty.  Sellers agree to maintain in force and effect until the Closing
Date any existing casualty insurance coverage on the Property. Sellers
represent and warrant to Buyer that its existing casualty insurance covers
the Buildings for 100% of the replacement value thereof (less a reasonable
deductible).  An "immaterial" part of the Buildings shall be deemed to have
been damaged or destroyed if either (i) the cost of repair or replacement
shall be $2,500,000 or less, or (ii) the damage to the Buildings may be
repaired (without regard to the cost therefor) within the period expiring
one hundred twenty (120) days after the Closing Date as scheduled prior to
such casualty, as reasonably determined by a reputable architect who is
jointly selected by Sellers and Buyer.

15.   DEFAULTS.

      A.    If Sellers shall tender the Deeds in compliance with the
Sellers' obligations hereunder, and Buyer shall fail or refuse to close
title hereunder as required by the terms of this Agreement, then the Escrow
Agent shall deliver the Deposit to Sellers (pro rata in proportion to the
allocation of the Purchase Price set forth in Paragraph 2(C)), and the
Sellers shall be entitled to retain the Deposit, free of any claim thereto
of Buyer, as liquidated damages, as their sole and exclusive remedy
hereunder, and neither party shall have any further rights or obligations
to the other hereunder (other than those obligations which expressly
survive the closing or termination hereof). In connection with the
foregoing, the parties recognize that Sellers will incur expense in
connection with the transaction contemplated by this Agreement and that the
Property will be removed from the market; further, that it is extremely
difficult and impracticable to ascertain the extent of detriment to Sellers
caused by the breach by Buyer under this Agreement and the failure of the
consummation of the transaction contemplated by this Agreement or the
amount of compensation Sellers should receive as a result of Buyer's breach
or default.  In the event the sale of the Property shall not be consummated
on account of Buyer's default, then the retention of the Deposit shall be
Sellers' sole and exclusive remedy under this Agreement by reason of such
default.


<PAGE>


      B.    If the transaction herein provided shall not be closed by
reason of Sellers' default under this Agreement or the failure to satisfy
the conditions set forth in this Agreement or the termination of this
Agreement in accordance with the terms hereof, then the Deposit shall be
returned to Buyer, and neither party shall have any further obligation or
liability to the other; provided, however, if the transaction hereunder
shall fail to close solely by reason of a material or wilful default by
Sellers, Buyer shall have fully performed its obligations hereunder and
shall be ready, willing and able to close, then Buyer shall be entitled to
specifically enforce this Agreement; and provided further however, if
Sellers shall willfully take actions so as to attempt to prevent the
availability of a specific performance to Buyer, then Buyer shall, at its
option, in lieu of specific performance, be entitled to a return of the
Deposit and reimbursement of its actual out-of-pocket costs paid to third
parties in connection with the transactions hereunder (such reimbursement
not to exceed $50,000 in the aggregate).  Except as set forth above, no
other actions, for damages or otherwise, shall be permitted in connection
with any default by Sellers. Notwithstanding anything to the contrary
contained herein, if the closing of the transaction hereunder shall have
occurred (and Buyer shall not have waived, relinquished or released any
applicable rights in further limitation), the aggregate liability of
Sellers arising to or in connection with the representations, warranties,
indemnifications, covenants or other obligations (whether express or
implied) of Sellers under this Agreement (or any document executed or
delivered in connection herewith) shall not exceed $2,000,000.00, which
amount shall be maintained by Sellers in Sellers' names until November 15,
1998, at which time, if no claim has been asserted by Buyer against
Sellers, Sellers may distribute such funds.  If a claim has been timely
made such funds (up to the amount that might be necessary to satisfy such
claim) shall continue to be held by Sellers until resolution of the claim.

      C.    The liability of Sellers hereunder for damages or otherwise
shall be limited to Sellers' interest in the Property including, without
limitation, the proceeds of any insurance policies covering or relating to
the Property, any awards payable in connection with any condemnation of the
Property or any part thereof, and any other rights, privileges, licenses,
claims, causes of actions or other interests, sums or receivables
appurtenant to the Property.  Sellers shall have no personal liability
beyond Sellers' interest in the Property, and no other property or assets
of Sellers shall be subject to levy, execution or other enforcement
procedure for the satisfaction of Buyer's claims.  In no event shall
Sellers' officers, partners, trustees, directors, agents, employees or
shareholders have personal liability in connection with the transactions
hereunder or otherwise.  No constituent partner in or agent of Sellers, nor
any advisor, trustee, director, officer, employee, beneficiary,
shareholder, participant, representative or agent of any corporation or
trust that is or becomes a constituent partner in Sellers (including, but
not limited to, JMB Realty Corporation or London & Leeds Development
Corporation or any affiliates thereof) shall have any personal liability,
directly or indirectly, under or in connection with this Agreement or any
agreement made or entered into under or pursuant to the provisions of this
Agreement, or any amendment or amendments to any of the foregoing made at
any time or times, heretofore or hereafter, and Buyer and its successors
and assigns and, without limitation, all other persons and entities, shall
look solely to Sellers' interest in the Property for payment of any claim
or for any performance, and Buyer, on behalf of itself and its successors
and assigns, hereby waives any and all such personal liability.
Notwithstanding anything to the contrary contained in this Agreement,
neither the negative capital account of any constituent partner in Sellers,
nor any obligation of any constituent partner in Sellers to restore a
negative capital account or to contribute capital to Sellers (or any
constituent partner of Sellers), shall at any time be deemed to be the
property or an asset of Sellers or any constituent partner thereof, and
neither Buyer nor any of its successors or assigns shall have any right to
collect, enforce or proceed against or with respect to any such negative
capital account or partner's obligation to restore or contribute.

22.   ASSIGNMENT.

      Buyer may not assign Buyer's interest in this Agreement without the
prior written consent of Sellers, except that Sellers' consent shall not be

As used herein,  "Affiliate" shall mean any subsidiary corporation or
