                   900 THIRD AVENUE OFFICE BUILDING

                          NEW YORK, NEW YORK
                   --------------------------------


ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.  On November 2, 1999, 900
Third Avenue Associates ("JMB/900"), a joint venture between Carlyle Real
Estate Limited Partnership - XV (the "Partnership") and Carlyle Real Estate
Limited Partnership - XIV ("Carlyle - XIV"), an affiliated partnership
sponsored by the Corporate General Partner of the Partnership, through
Progress Partners, sold the land, building and related improvements of the
900 Third Avenue office building (the "Property"), located in New York, New
York.  As a result of the acquisition of the interests of the former
venture partners in Progress Partners earlier this year, JMB/900 owns,
directly or indirectly, substantially all of the interests in Progress
Partners.  The purchaser of the Property, Paramount Group, Inc., a Delaware
corporation, is not affiliated with the Partnership or its General Partners
and the sale price was determined by arm's length negotiations. The
Property is an approximate 560,000 square foot office building, and as of
the date of sale was approximately 98% occupied.

     The sale price was approximately $163,000,000.  Upon closing,
Progress Partners received cash of approximately $61,700,000 (net of
closing costs but before prorations). The cash received is also net of the
repayment of the mortgage loan secured by the Property of approximately
$87,000,000, a prepayment penalty of approximately $5,800,000 and the final
payment of approximately $2,500,000 to the former venture partners pursuant
to a settlement agreement in which JMB/900 purchased all of the former
venture partners' interests in Progress Partners.  Additionally, in
connection with the sale of the Property, Progress Partners received the
balance (approximately $16,100,000) in an escrow account that had been
controlled by the mortgage lender for the payment of real estate taxes and
re-leasing costs for the Property.  The Property was classified as held for
sale as of July 1, 1998 and therefore has not been subject to continued
depreciation from such date for financial reporting purposes. As a result
of this sale, JMB/900 expects to recognize a gain of approximately
$55,000,000 and $78,000,000 for financial reporting and Federal income tax
purposes, respectively. The Partnership's share of such items is expected
to be approximately $36,700,000 and $52,000,000, respectively.
Additionally, as a result of this transaction, JMB/900 expects to recognize
extraordinary losses of approximately $5,900,000 (of which the
Partnership's share is approximately $4,000,000) for financial reporting
purposes.  As is customary in such transactions, Progress Partners has
agreed to certain representations, warranties and covenants with stipulated
survival periods, which expire on September 15, 2000. Although it is not
expected, Progress Partners may ultimately have some liability under such
representations, warranties and covenants, which are limited to actual
damages and shall in no event, exceed $2,000,000. As required by the sale
agreement, Progress Partners has placed this amount into escrow.

     The terms of the JMB/900 venture agreement generally provide that
sale proceeds will be allocated or distributed, as the case may be, 66.67%
to the Partnership and 33.33% to Carlyle - XIV.

     The Partnership Agreement of the Partnership provides that subject to
certain conditions, the General Partners shall receive as a distribution
from the proceeds from the sale of a real property up to 3% of the selling
price, and that the remaining proceeds (after expenses and retained working
capital) be distributed 85% to the Limited Partners and 15% to the General
Partners. However, prior to such distributions being made, the Limited
Partners are entitled to receive 99% of net sale or refinancing proceeds
and the General Partners shall receive 1% until the Limited Partners have
received (i) cash distributions of sale or refinancing proceeds in an
amount equal to the Limited Partners' aggregate initial capital investment
in the Partnership and (ii) cumulative cash distributions from the
Partnership's operations which, when combined with the sale or refinancing
proceeds previously distributed, equal a 6% annual return on the Limited
Partners' average adjusted capital investment for each year (their initial


<PAGE>


capital investment reduced by sale or refinancing proceeds previously
distributed) commencing with the third fiscal quarter of 1986. Since the
Limited Partners have not yet received, and are not expected to receive,
the amounts stipulated in items (i) and (ii) above, the General Partners
are not expected to receive any share of the proceeds from this sale of
this Property.


ITEM 7.    FINANCIAL STATEMENTS AND EXHIBITS

     (a)   Financial Statements. Not applicable

     (b)   Proforma financial information - Narrative

           As a result of the sale of the Property, after November 2,
1999, there will be no further rental income, interest income, mortgage and
other interest, property operating expenses, amortization of deferred
expenses and venture partners' share of venture operations in the
consolidated financial statements of the Partnership, which for the nine
months ended September 30, 1999 were approximately $17,609,000, $502,000,
$6,116,000, $7,409,000, $470,000 and ($2,105,000), respectively. Such
operating results reflect the classification of the Property as held for
sale as of July 1, 1998, and therefore the Property has not been subject to
continued depreciation from such date. Additionally, as a result of such
sale, there will be no further assets and liabilities related to the
Property, which at September 30, 1999 consisted of cash of approximately
$4,329,000, escrow deposits of approximately $14,255,000,  prepaid expenses
of approximately $1,349,000 and other current assets of approximately
$233,000, property held for sale or disposition of approximately
$97,472,000, deferred expenses of approximately $2,037,000,  accounts
payable of approximately $389,000, accrued interest payable of
approximately $677,000, note payable of approximately $2,500,000, long term
debt (including current portion) of approximately $86,708,000, tenant
security deposits of approximately $1,003,000 and venture partner's
subordinated equity in venture of approximately $10,548,000.

recourse by TIAA in favor of Buyer's Lender, all in exchange for payment
directed by Seller to TIAA at Closing of the outstanding principal amount

Balance") pursuant to TIAA's standard pay-off letter.  Buyer shall
cooperate with Seller in seeking to obtain the assignment and Seller hereby
agrees to execute and deliver a so-called "275 Affidavit" in connection
therewith.  In the event the TIAA Loan Documents are assigned to Buyer's
Lender in accordance with this subparagraph, then Buyer shall be entitled

of all sums directed by Seller to be paid to TIAA.  Buyer shall not be
required to pay the costs, if any, charged or required by TIAA to effect
such assignment, including, without limitation, any prepayment fees and
attorneys' fees and disbursements.  Following such assignment and pay-off,
Seller shall not in any way be liable to Buyer or Buyer's Lender for any
obligations and liabilities arising under or related in any way to the TIAA
Loan Documents, and either (i) Buyer's Lender shall acknowledge in writing
either concurrent with or prior to the assignment of the TIAA Loan
Documents that Seller has no liability thereunder following such
assignment, or (ii) the TIAA Loan Documents shall be expressly marked to
ensure that Seller has no liability thereunder following such assignment,
except for those obligations of Seller to TIAA (but not to any successors
or assigns or other third parties) which survive repayment and satisfaction
of the mortgage evidenced by the TIAA Loan Documents.  Seller shall be
under no obligation to make any covenants, representations or warranties to
Buyer or TIAA relating to such assignment.  If TIAA will not agree to
assign the TIAA Loan Documents to Buyer's Lender in the manner provided for
hereunder, or, notwithstanding anything herein to the contrary, Seller
elects for any reason not to cause such assignment, Buyer shall be entitled
to a credit (the "Mortgage Tax Credit") against the Purchase Price in the
amount of $2,365,000; provided that Buyer shall not be entitled to the
Mortgage Tax Credit if the primary reason TIAA will not agree to assign the
TIAA Loan Documents is due to Buyer or Buyer's Lender failure to either
execute customary documents relating to the mortgage assignment or accept
the Assignment Document in the form attached, including, without
limitation, conditioning Buyer's Lender's acceptance of the Assignment
Document on the execution or delivery of any other agreement,  undertaking,
representation or warranty by TIAA, Seller or any other third party, except
for the issuance of the Lender's Title Policy or Marked Up Commitment to
Buyer's Lender at Closing.

Buyer has the right to, and elects to, extend such initial Due Diligence
Period in accordance with Section 9 (d) below; such date to be selected by
Buyer upon not less than fifteen (15) days prior written notice to Seller,
provided that such date shall be a regular business day or (b) such other
date as may be agreed upon in writing by Buyer and Seller.  Buyer shall
have the right to adjourn the Closing Date for good and sufficient cause by
delivering written notice as required herein of such adjournment to Seller,
which notice shall specify the adjourned date on which Closing shall occur
and shall explain with reasonable specificity and detail such cause.  Buyer
shall be entitled to only one such adjournment.  If Buyer gives such notice
at least twenty-four (24) hours prior to the Closing Date, such adjournment
may be up to but shall not to exceed five (5) business days and if Buyer
gives such notice less than twenty-four hours prior to the Closing Date but
prior to 12:00 p.m. on the Closing Date, such adjournment may be up to but
shall not to exceed two (2) business day.  Buyer agrees, notwithstanding
the foregoing, that it has no right to request or require an adjournment of
the Closing Date in order to effectuate the 1031 Exchange described in
Section 31 hereto.  Seller shall have the right to adjourn the Closing Date
for good and sufficient cause by delivering written notice as required
herein of such adjournment to Buyer prior to Closing, which notice shall
specify the adjourned date on which Closing shall occur and shall explain
with reasonable specificity and detail such cause.  Seller shall be
entitled to only one such adjournment, subject to the proviso set forth in
the next following sentence hereof.  If Seller gives such notice at least
twenty-four (24) hours prior to the Closing Date, such adjournment may be
up to but shall not to exceed five (5) business days and if Seller gives
such notice less than twenty-four hours prior to the Closing Date but prior
to 12:00 p.m. on the Closing Date, such adjournment may be up to but shall
not to exceed two (2) business days; provided that if the cause for
adjournment, without limitation of any other, is because Seller is not
prepared to deliver the Estoppel Certificates to be delivered to Buyer
pursuant to subparagraph (k) of Section 4.2 below (and Buyer is not
prepared to waive such delivery) or because TIAA has not yet agreed to
assign the TIAA Loan Documents in accordance with this Agreement, then
Seller shall be entitled to an additional five (5) business day adjournment
to satisfy such matters.  Notices of adjournments as provided in this
Section 4.1 may be delivered by facsimile transmission to the FAX numbers
set forth in Section 14 below (and such notice shall be deemed given on the
date set forth in Section 14 below).

           4.2.  Closing.  On the Closing Date, the following actions
shall be taken, all of which will be deemed taken simultaneously and no one
of which will be deemed completed until all have been completed:

                 (a)  The Deed in recordable form, containing the
covenant required by subsection 5 of Section 13 of the Lien Law of the
State of New York, shall be delivered by Seller to Buyer.

credit; provided, however, that as for those letters of credit that require
amendment in order to enable Buyer to exercise the rights of beneficiary
thereunder, copies thereof shall be delivered to Buyer at Closing and
Seller and Buyer shall cooperate and expend commercially reasonable efforts
to obtain such amendments after Closing, for the benefit of and delivery to
Buyer.  Should the issuer of any such letter of credit charge for such

of credit) and Buyer shall pay any amount charged in excess thereof.

                 (o)  Any and all reasonable and customary documents

(iii) Seller shall not be required to make any representations and

     5.    Prorations; Closing Expenses; and Adjustments.

           5.1.  Prorations.  The following items are to be apportioned
between Buyer and Seller as of 11:59 p.m. of the day before the Closing
Date, except as otherwise set forth below:

                 (a)  Rents and Charges.  Basic rents, percentage rents
and payments or reimbursements for taxes, utilities and operating expenses
and all other charges or reimbursables as and when collected under the
Leases including without limitation charges for any special services
provided to any Tenant, overtime HVAC or special cleaning (collectively,
the "Rents"); provided, however, that all Rents collected after the Closing
under the Leases shall be applied, on a Lease by Lease basis and unless any
Tenant specifies otherwise with respect to a payment, first, to satisfy
obligations attributable to the payment period in which Closing occurs,
second, in payment of Rents due and payable for the period after the
Closing Date, and third, after Rents for all current periods have been
satisfied in full, in payment of Rents in arrears for the periods prior to
the payment period in which the Closing occurs.  At Closing, Seller shall
assign to Buyer all of its claims or causes of action against existing
Tenants, if any, provided, however, that if any such Tenant files a
counterclaim or initiates an action against Seller which is not covered by
Buyer's indemnity provided for under Section 33 below, then Seller shall
retain such claims or causes of action (or such claims or causes of action
shall be reassigned to Seller) to the extent necessary for Seller to assert
a complete setoff or other defense against such Tenant's counterclaim or
other action.  If at the time of Closing (as reflected in a schedule to be
delivered by Seller at Closing of all amounts known to Seller as due and
payable by any Tenant for the period prior to Closing but uncollected as of
Closing, whether or not past due) or thereafter there are Rents owed by
Tenants to Seller, then Buyer will make commercially reasonable efforts,
without suit, to collect the same for the account of Seller and any such
Rents, if received, shall have been received by Buyer for the account of
Seller and will be remitted by Buyer to Seller within 15 days of receipt.
If, however, Buyer, in its sole discretion, elects to sue any Tenant for
Rents in arrears for periods after Closing, Buyer shall include in such
suit (and, upon recovery, pay to Seller) amounts due Seller from such
Tenant (net of any prior collections and payments to Seller) for periods
prior to Closing and Seller shall be responsible for incremental legal fees
and expenses, if any, reasonably incurred by Buyer's counsel in prosecuting
such action on Seller's behalf at the same time it is prosecuting such
action on Buyer's behalf.  Notwithstanding the foregoing, as to any Rents
due Seller which are unpaid as of the date which is 45 days after such
Rents are due, at Seller's option upon written notice to Buyer, Seller may
for its own account, take such action as it may deem advisable to recover
such past due Rents including the exercise of all legal or equitable
remedies (except that Seller may not exercise any right to terminate a
Lease, evict a Tenant or attach any Rents that become due after Closing)
and from and after the date Seller gives Buyer notice of the exercise of
such right, that part of the Rents due Seller which Seller elects to
collect shall be deemed reassigned to Seller without any further document
or instrument, and Buyer shall be released from any further obligation to
make any efforts to collect such amounts except to reasonably cooperate
with Seller's collection efforts (and Seller further agrees promptly to
deliver to Buyer copies of all correspondence and legal papers filed in
connection with such recovery efforts by Seller).  Subject to the
foregoing, Buyer shall also provide Seller with a written report on a
monthly basis setting forth the status of the billing and collection of the
Rents attributable to all periods prior to Closing.  Seller expressly
agrees that if Seller receives any Rents directly from Tenants after the
Closing Date, Seller shall remit same to Buyer (but only to the extent such
Rents have not been reassigned to Seller as provided herein) within 15 days


<PAGE>


after receipt thereof and Buyer shall deliver to Seller the amount thereof,
if any, to which Seller is entitled pursuant to the terms hereof within 15
days after receipt thereof.  All prepaid Rents and charges for the period
following the Closing and all cash security or other cash deposits of
Tenants held by Seller shall be paid over (or credited) by Seller to Buyer
at Closing.  Buyer shall also provide Seller with a written report on a
monthly basis setting forth the status of the billing and collection of the
Rents attributable to all periods prior to Closing.  Except as set forth
herein, Seller shall not be entitled to collect or attempt to collect Rents
from Tenants except those whose Leases or rights to possession under the
Leases have been terminated and have vacated their premises.

           (b)   All percentage rentals received under the Leases for the
year in which the Closing Date occurs shall be apportioned between Buyer
and Seller pro-rata based on the percentage of such year the Project is
owned by each. All other charges to or contributions by Tenants under the
Leases for the period under such Leases which includes the Closing Date,
including without limitation, payments or reimbursements, whether for
taxes, utilities, other operating expenses or otherwise, shall be
apportioned on the basis of the ratio which the expenses actually paid by
each party for such period bears to the total of all expenses with respect
to such period for which such payment was made by the Tenant.  Such
apportionments shall be adjusted as soon as practicable after the end of
the current lease year, and at such time Buyer shall furnish Seller with
statements in reasonable detail showing the calculation of such
apportionments, rents and payments, and any adjustments shall be allocated
for the portion to which it applies.  If either Seller or Buyer shall have
collected more than its share of such amounts payable under any Lease
pursuant to this Section, such party shall promptly remit to the other the
amount of such excess.  If any Tenant is entitled to refunds of any such
rents or charges, such refunds shall be paid by the party hereto that
received such rents or charges.

                 (c)  Real property taxes and assessments and refunds for
the tax year in which the Closing occurs.  In the event a final tax bill is
not available for such year at the Closing, the required proration shall be
made on the basis of the most recent available tax bill and a further
proration shall be made between the parties when the tax bill for the tax
year in which the Closing occurs becomes available.  If any proceeding for
certiorari or other proceeding to determine the assessed value of the
Project or the real property taxes payable with respect to the Project
shall have been commenced prior to, and is pending as of, the Closing Date
(a "Tax Protest"), Buyer and Seller shall agree upon the certiorari counsel
who shall continue the prosecution of such proceeding or proceedings to
completion. Buyer shall have the authority to settle or compromise any
claim relating solely to the tax year in which the Closing Date occurs and
the tax years thereafter and to receive and deliver to Seller any real
estate tax refunds or abatements due to Seller net of costs of collection
and refunds due to Tenants.  Buyer shall consult with Seller with respect
to settling or compromising claims relating to the tax year in which the
Closing Date occurs.  Seller shall have the right to be promptly informed
as to the status of such proceedings.  Seller shall have the authority to
settle or compromise any claim relating solely to any tax year prior to the
tax year in which the Closing Date occurs and to keep all amounts received
on such claims, net of any refunds due to Tenants.  The parties agree to
cooperate with each other, and to execute any and all documents reasonably
requested by the other party, in furtherance of the foregoing.

                 (d)  Fees and charges under such of the Service
Contracts as are being assigned to and assumed by Buyer at the Closing, on
the basis of the periods to which such Service Contracts relate.



<PAGE>


                 (e)  Utility charges, including water, sewer, steam,
electricity and gas, vault taxes and maintenance charges, if any, for
sewers (other than those charges required to be paid directly to the
utility companies by any Tenant under its Lease).  In conjunction with such
prorations, Seller will assign to Buyer all utility deposits which are
assignable (and Seller shall be credited with such amounts) and notify, or
cause to be notified, all utilities servicing the Project of the change in
ownership and direct that all future billings be made to Buyer at the
address of the Project with no interruption of service.  Seller shall use
its reasonable efforts to procure final meter readings for all utilities as
of the Closing Date and to have bills rendered directly to Seller.

                 (f)  At least three (3) business days prior to Closing,
Buyer and Seller jointly shall prepare a closing statement, subject to and
in accordance with the terms hereof, indicating the net amount due to
either party as a result of the adjustments and prorations provided for
herein.  Any errors in the calculation of apportionments shall be corrected
or adjusted as soon as practicable (but not more often than monthly) after
the Closing Date.  If it is impracticable to apportion certain items
hereunder on the Closing Date, such items shall be apportioned and paid as
soon as practicable thereafter. Buyer agrees to take necessary actions
after Closing in a timely manner in order to make the adjustments and
reprorations provided for hereunder, including, without limitation billings
to Tenants and completion of Buyer's other undertakings pursuant to
Subsection (b) above (other than collections) no later than April 30, 2000.

                 (g)  The provisions of this Section 5.1 shall survive
Closing.

           5.2.  Closing Expenses.  Except as expressly set forth in
subparagraph (c) of Section 3 and in this Section 5.2, Buyer shall be
responsible for all taxes, transfer taxes, documentary stamps, recording
and other similar fees and costs incurred in connection with the
transactions contemplated hereby including the recording of a mortgage on
the Project.  Buyer shall also be responsible for all premiums and expenses
incurred in connection with the preparation of the Survey and the Title
Report and the issuance of the Title Policy and the Lender's Title Policy.
Seller shall bear and be responsible for the payment or discharge of the
New York City real property transfer taxes and New York State real property
transfer taxes incurred in connection with the sale of the Project
("Transfer Taxes"), if any, and any costs or expenses with respect to
Transfer Taxes. Seller and Buyer shall take any and all action necessary in
order to comply with the provisions of New York State and New York City law
relating to the Transfer Taxes, including, without limitation, the
preparation, execution and filing of any and all returns, affidavits and
questionnaires, if any, required in respect of the Transfer Taxes in
connection with the purchase of the Project and the payment of the Transfer
Tax shown due on such returns with such returns. The parties hereby
acknowledge and agree that the value of the personal property delivered in
connection with the sale is de minimis.  Except as otherwise provided for
in this Agreement, each party shall bear its own costs and expenses.

           5.3.  Adjustments.  Leasing commissions, tenant allowances and
similar monetary payments, if any, due in respect of leases or
modifications of Leases entered into during the Contract Period in
accordance with Section 6.1(b) below, or arising in connection with
renewals, extensions or expansions of existing Leases that become effective
during the Contract Period (except if such renewals, extensions or
expansions are modifications of the terms of existing Leases not made in
accordance with Section 6.1(b) below) shall be prorated over the term of
the Leases in question, except that Buyer shall be solely responsible for
the portion thereof attributable to the period before Closing to the extent


<PAGE>


Seller does not receive Rent due under the applicable Lease for such period
(including any "free rent" period) and to all periods after Closing. To the
extent Seller has paid all or any part of such leasing commissions, tenant
allowances, or other similar monetary payments for which Buyer is
responsible, Buyer shall reimburse Seller for such payments at Closing and
Seller shall provide Buyer to its reasonable satisfaction with evidence of
such payment.  All leasing commissions and tenant allowances, if any, for
the current term of Leases shall be paid by Seller, regardless of when such
commissions or allowances are due, and leasing commissions and tenant
allowances, if any, for any renewals, extensions or expansions under any
such Leases commencing after the date hereof shall be the responsibility of
Buyer.  This provision shall survive the Closing.  [OPEN ISSUES PENDING
WITH RESPECT TO BUYER'S PROPOSED RIDER 13]

     6.    Covenants.

           6.1.  Covenants of Seller.  Seller hereby covenants and agrees
with Buyer as follows:

                 (a)  At all times during the Contract Period, Seller
shall operate and manage the Project in the normal and ordinary course of
business and in a manner consistent in all material respects with Seller's
past practices.  Without limiting the generality of the foregoing, Seller
shall:

                      (i)   keep the Licenses and Permits (as hereinafter
defined) required, if any, for the lawful operation of the Project as
currently operated in full force and effect;

                      (ii)  maintain in full force and effect the
insurance policies described in Exhibit M;

                      (iii) Between the date hereof and the Closing Date,
Seller will advise Buyer of any written notice Seller receives after the
date hereof from any governmental authority relating to the violation of
any law or ordinance regulating the condition or use of the Project; and

                      (iv)  Seller shall reasonably cooperate with
Buyer's attempts to obtain subordination and/or non-disturbance and
attornment agreements from Tenants to the extent requested by Buyer's
Lender or contemplated under the applicable Leases.

                 (b)  Throughout the Contract Period, (i) Seller shall
not, without Buyer's consent, modify the terms of any Leases or enter into
any new leases for the Property, (ii) Seller shall not enter into any new
service contracts affecting the Property, without Buyer's consent, unless
such service contracts (or the applicable terms thereof affecting the
Property) are terminable upon not more than thirty (30) days' notice
without a termination fee or if Seller agrees to pay any fee, in which case
Buyer's consent shall not be required, (iii) without Buyer's prior written
consent, Seller shall not grant any consent of landlord under a Lease
unless such consent is for a de minimis matter or unless Seller is advised
in writing by its legal counsel that there is a material risk that the
refusal to grant such consent may be found to constitute a breach of such
Lease, (iv) without Buyer's prior written consent, Seller shall not
undertake or approve any capital improvements or repairs except as required
by emergency and except for non-capital repairs made in the ordinary course
of business, (v) without Buyer's prior written consent, Seller shall not
consent to any assignment or sublease in connection with any Lease unless
Seller is advised in writing by its legal counsel that there is a material
risk that the refusal to grant such consent may be found to constitute a
breach of such Lease.  In any case where Seller intends to grant its
consent under a Lease or to an assignment or sublease based on such advice


<PAGE>


of Seller's legal counsel, Seller will notify Buyer in writing of such
intent prior to granting such consent.  Within three (3) business days of
such notice, if the Due Diligence Period has expired (including any
extensions thereof) and Buyer agrees in writing to indemnify, defend and
hold harmless Seller from any loss, damage, claims or expenses (including
attorney's fees) caused or resulting from Seller's failure to grant such
consent, then Seller shall not grant such consent without Buyer's prior
written consent.  With respect to all matters requiring Buyer consent
hereunder, if Buyer does not notify Seller in writing, within five (5)
business days after Buyer's receipt of a proposed modification of Lease or
new lease or service contract, that it does not consent to such proposed
modification, new lease or service contract, then such proposed
modification or new lease or service contract shall conclusively be deemed
to have been approved by Buyer. Any new leases or service contracts entered
into by Seller in accordance with the terms of this Section 6.1(b) shall be
assigned by Seller and assumed by Buyer on the Closing Date.

                 (c)  Throughout the Contract Period, Seller shall not:

                      (i)   bring (or permit, to the extent within
Seller's knowledge and control, to be brought) Hazardous Materials or
substances on or into the Project in violation of Environmental Laws; or

                      (ii)  remove or dispose of (or permit, to the
extent within Seller's knowledge and control, to be removed or disposed of)
any Hazardous Materials or substances existing on or in the Project in
violation of Environmental Laws; or

                      (iii) remove (unless the same are replaced with
similar or comparable items of at least equal quality prior to Closing) any
fixtures, equipment or personal property included hereunder;

                      (iv)  without Buyer's prior written consent in each
instance, which consent may be withheld, conditioned or delayed in Buyer's
sole and absolute discretion, create any encumbrances affecting title to
the Property (other than inchoate mechanic liens for labor and materials
provided to the Project in the ordinary course of operations) or sell or
transfer any portion of or interest in the Property. Unless and until this
Agreement shall be terminated in accordance with the terms hereof, Seller
shall not solicit or pursue or entertain any offers to purchase the
Project, nor shall Seller enter into any negotiations with third parties
with respect to a sale of the Project; or

                      (v) take any actions which would cause Seller to be
in default to any material extent with respect to the obligations of Seller
under the agreements set forth in paragraphs __, __ and ___ of Exhibit F.

           6.2.  Covenants of Buyer; Other Covenants.

                 (a)  Prior to the expiration of the Due Diligence
Period, Buyer shall notify Seller in writing of any Service Contract that
Buyer does not desire to assume.  Seller shall pay all costs associated
with such termination(s).  However, Seller shall assume no responsibility
for the termination of any Service Contracts by the Closing Date (and Buyer
shall assume Service Contracts not so terminated) unless Buyer's notice to
Seller is given in sufficient time to permit Seller to give any notice of
termination required under the terms of such Service Contracts.  Seller
shall terminate the contract for Kennedy Wilson Properties, in its capacity
as property manager and leasing agent, which terminations shall be
effective on the Closing Date.



<PAGE>


                 (b)  Buyer shall not unreasonably disrupt the business
and operation of the Project during the conduct of its inspections, studies
and tests hereunder or the rights of Tenants under their Leases.

                 (c)  (i) Any Known Breach (as defined hereinafter) with
respect to which Buyer fails to give written notice prior to Closing shall
be deemed waived and Buyer shall have no right or claim or other remedy
with respect thereto or arising therefrom pursuant to Section 32 of this
Agreement or otherwise against Seller.  As used herein, a "Known Breach"
means any breach of or inaccuracy in any of the Seller's representations or
warranties which Buyer has or had knowledge of at or prior to Closing.
Buyer shall give Seller written notice of a Known Breach promptly after
Buyer acquires knowledge thereof.  For purposes of this subsection, Buyer
shall be deemed to have knowledge of only those matters actually known by
Albert Behler and Dan Lauer, provided that such persons remain responsible
for reviewing on Buyer's behalf the results of the Buyer's investigation
during the Due Diligence Period (and extensions thereof) and remain
responsible for closing the purchase and sale contemplated hereunder,
without any duty to investigate and with any imputed or constructive
knowledge excluded.

                 (ii)  Within five (5) business days after Seller's
receipt of Buyer's written notice of a Known Breach or within five (5)
business days after the expiration of the Due Diligence Period (and any
extensions thereof), whichever is later, Seller shall be obligated to cure
any such Known Breach, provided that if at the expiration of such 5-
business day period Seller is attempting in good faith to cure such Known
Breach and such Known Breach is at that point susceptible of being cured,
the cure period shall be extended for a reasonable period of time (not to
exceed fifteen business days after whatever the Closing Date would have
been if the Closing had not been adjourned by Seller as provided herein) as
may be necessary to complete such cure so long as Seller is continuing in
good faith to diligently cure such breach ("Seller's Cure Period").  If the
Closing Date occurs during Seller's Cure Period, Seller shall be entitled
to adjourn the Closing Date until expiration of said Cure Period.
Notwithstanding the foregoing or anything to the contrary in this
Agreement, Seller shall not be required to expend any amounts to cure a
Known Breach in excess of the Damage Limitation (as defined hereinafter).
As used herein, the "Damage Limitation" means (a) $1,000,000 with respect
to a Known Breach, other than a wilful and intentional act taken after the
date of this Agreement for which Seller is obligated under clauses (b) or
(c) below; (b) an amount equal to the net proceeds of sale which would
otherwise be due Seller hereunder (but for the wilful act of Seller
described herein) with respect to a monetary Known Breach which is a wilful
and intentional act of Seller (but not of its agents or third-party
managers) taken after the date of this Agreement, for which Buyer's damages
or other remedies are of a liquidated nature that is readily ascertainable;
and (c) $6,000,000 with respect to all other Known Breachs which arise out
of a wilful and intentional act of Seller (but not of its agents or third
party managers) taken after the date of this Agreement.  Seller may use the
proceeds from the sale to cure any Known Breach and shall use the proceeds
of sale to cure any Known Breach described under clause (a) which is
liquidated and monetary in nature and readily ascertainable and under
clause (b), in each case subject to the applicable Damage Limitation.
Seller shall provide Buyer with notice of whether or not it has cured a
Known Breach on or prior to the expiration of the Seller's Cure Period and
evidence reasonably satisfactory to Buyer of any such cure.  Notice of cure
as required herein may be delivered by facsimile transmission to the FAX
numbers set forth in Section 14 below (and such notice shall be deemed
given on the date set forth in Section 14 below).



<PAGE>


                 (iii)  If Seller does not cure a Known Breach (or does
not provide the Buyer with notice of cure and reasonably satisfactory
evidence thereof as provided above or does not provide Buyer with a written
indemnity on terms satisfactory to Buyer against any such Known Breach)
prior to the expiration of the Seller's Cure Period, Buyer shall, within
three (3) business days after expiration of Seller's Cure Period, as its
sole and exclusive remedy with respect to such failure, either (A) accept
title to the Project subject to such Known Breach and receive at Closing a
credit against the Purchase Price in the amount agreed upon by the parties
or if the parties cannot agree on the amount of such credit, Buyer shall
pay the Purchase Price without offset or reduction on account of such Known
Breach and may receive a refund after Closing to the extent provided
herein, or (B) terminate this Agreement by written notice to Seller, in
which event the Deposit, together with all accrued interest thereon, shall
be returned to Buyer, any documents or other information theretofore
delivered to Buyer shall be returned to Seller and thereafter neither party
shall have any further rights or obligations hereunder, except as provided
in Sections 9(a), 13 and 26; provided that if the Known Breach is not
material, then Seller's sole remedy shall be as set forth in the foregoing
clause (A).  If the parties cannot agree on the amount of the credit due
Purchaser on account of the Known Breach, then the parties shall reasonably
estimate the damages, if any, to Buyer resulting from a Known Breach
(subject to the limitations provided herein), and an amount equal to such
estimate shall be deposited in the escrow provided in Section 30(b) (the
"Section 6.2 Deposit") and the Buyer shall be entitled to a refund after
Closing in the amount of damages, if any, suffered by Buyer on account of
such Known Breach which shall in any event not exceed the Section 6.2
Deposit.  Subject to the foregoing, if the parties are unable to reach
agreement as to resulting damages or any such estimate, each party shall
estimate in good faith the amount of such damages (not to exceed the
applicable limitations set forth herein) and notify the other party in
writing of such estimated amount prior to the Closing.  Seller shall
deposit as the Section 6.2 Deposit  an amount equal to Buyer's estimate
(such estimate not to exceed the applicable limitations set forth herein),
less out of pocket expenses reasonably substantiated by Seller as
theretofore expended by Seller after the date of the relevant notice of the
Known Breach but prior to Closing in bona fide attempts to cure the Known
Breach.  Buyer's estimate under this Section 6.2(c) shall not include any
amounts included in Buyer's estimate under Section 9(b).

           (d)  Prior to the Closing, Buyer shall not, with regard to any
matter specifically related to the Project, communicate in any manner with
any governmental authorities having jurisdiction over the Project (other
than routine inquiries that would not have the effect of causing such
authorities to take any action with respect to the Project) without first
affording Seller a reasonable opportunity to obtain information regarding,
or to attempt to resolve or otherwise deal with, such matter to Buyer's
reasonable satisfaction.

     7.    Representations and Warranties of Seller.  Seller hereby
represents and warrants to and covenants with Buyer that:

                 (a)  Seller has not been served with notice of any
pending litigation, nor has Seller been threatened in writing with
litigation relating to the Project, for which Buyer or the Project could be
liable, except as set forth on Exhibit O, if any.

                 (b)  Except as disclosed in the Rent Roll or in writing
to Buyer prior to Closing, no base rent has been paid more than one (1)
month in advance by any Tenant.

                 (c)  Except as otherwise set forth on Exhibit F attached
hereto or in the so-called "Violations Search" conducted by the Title
Insurer with respect to the Project, Seller has not received any written
notice from any governmental agency, lender or any Tenant that the Project
(or any portion thereof) is in violation (which has not heretofore been
corrected or otherwise satisfied) of (1) any of the requirements of
restrictive covenants or other encumbrances affecting the Project (or any
portion thereof) and (2) any applicable laws, regulations, codes, orders,
ordinances, rules and statutes bearing on the ownership, operation or use
of the Project, including, without limitation, those relating to health,
safety, building, fire, zoning, accessibility, and land use (collectively,
"Applicable Laws").  There is no pending, and Seller has received no notice
of any threatened, condemnation of all or any portion of the Project.  No
casualty has occurred with respect to the Project within the 18 months
preceding the date hereof that has not heretofore been repaired or
restored.

                 (d)  The Rent Roll lists all of the Leases as of the
date of this Agreement.  There are no leases, licenses or use and occupancy

Tenant is in arrears in the payment of rent and Seller has not sent written
notice to any Tenant claiming that such Tenant is in default, which default
remains uncured, and, as of the date hereof, Seller has no knowledge of any
monetary or other material default by any Tenant, other than as set forth
on the Rent Roll, with respect to which Seller has not sent a notice of
default.  Except as otherwise disclosed to Buyer as set forth on the Rent
Roll, as of the date hereof, Seller has received no notice of any claim by
a Tenant against Seller or any prior landlord that has not been resolved
for any security deposit or of any Tenant defense or off-sets to rent.  To
Seller's knowledge, Seller is not in default of any of its monetary
obligations or in material default of any  other obligations as landlord
under any Lease. No action or proceeding instituted against Seller by any
Tenant is currently pending in any court with respect to the Project.
There are no security deposits not set forth in the Rent roll that have
been paid (or, with respect to letters of credit, delivered) to Seller by
or on behalf of any Tenant, or with respect to any of the Leases. Seller
has not received any notice from any Tenant claiming that Seller is in
monetary or other material default under the Lease with such Tenant, which
default remains uncured.

with its terms; Seller has all necessary right and power required in
connection with, and has taken all necessary action to authorize and
approve, the execution and delivery of this Agreement and the consummation

Closing Date, except for contracts that can be cancelled on not more than
30 days' notice without penalty or fee except for penalty or fee which
Seller agrees to pay; there are no agreements which will bind the Property
(including all amendments, modifications and supplements thereto) after the
Closing Date other than the Permitted Exceptions, those described on

this Agreement) and as otherwise disclosed hereunder; Except as set forth
on Exhibit I, (i) all of the Service Contracts are in full force and effect
as of the date of this Agreement, (ii) no action or proceeding instituted
against Seller by any party to a Service Contract (each, a "Contract

violate any law, rule, judgment, regulation, order, writ, injunction or
decree of any court or the United States of America or the State of New
York or any political subdivision of either of the foregoing, to the extent
any of the foregoing have jurisdiction over the Seller or the Project, or
any decision or ruling of any arbitrator to which Seller is a party or by
which Seller or the Project is bound or affected, such that Seller's
performance hereunder would be materially and adversely impacted on account
of such violation.

                 (i)  Seller has no employees.  No employee of any other
entity who works on or for the Project shall have any employment, benefit

<PAGE>


     Except as expressly set forth above in this Section 7 or elsewhere in
this Agreement, Buyer agrees to acquire the Project "As Is, Where Is"
solely on the basis of its own financial, environmental and physical
examinations, review and inspections; Seller hereby disclaiming all implied
warranties with respect to real or personal property.

     For purposes of this Agreement, "Seller's knowledge" shall mean only
the actual knowledge of Andrea Pauls Backman, Senior Vice President and
Portfolio Manager of JMB Realty Corporation and Gail Spencer, on-site
building manager for Seller's third party property manager for the
Property, after having such persons review the representations and
warranties contained herein but otherwise without having any duty to
investigate and with any imputed or constructive knowledge being excluded.

     8.    Representations and Warranties of Buyer.  Buyer hereby
represents and warrants to Seller as follows:

                 (a)  Buyer is a corporation duly organized, validly
existing and in good standing under the laws of the State of New York and
has the requisite power and authority to carry on its business in the State
of New York as it is now being conducted; This Agreement constitutes the
legal, valid and binding obligation of Buyer enforceable in accordance with
its terms.

                 (b)  The execution and delivery of this Agreement and
the performance by Buyer of its obligations hereunder are not and will not
violate any law, rule, judgment, regulation, order, writ, injunction or
decree of any court or the United States of America or the State of New
York or any political subdivision of either of the foregoing, to the extent
any of the foregoing have jurisdiction over the Buyer or the Project, or
any decision or ruling of any arbitrator to which Buyer is a party or by
which Buyer or the Project is bound or affected, such that Buyer's
performance hereunder shall be materially and adversely affected on account
of such violation.

                 (c)  Buyer has all necessary right and power required in
connection with, and has taken all necessary action to authorize and
approve, the execution and delivery of this Agreement and the consummation
of the transactions contemplated by this Agreement.

                 (d)  No consent of any third party is required for the
entering into this Agreement and the performance by Buyer hereunder.

                 (e)  Each person signing this Agreement on behalf of
Buyer is authorized to do so.

     9.    Title and Other Matters.

                 (a)  Buyer shall have until August 23, 1999 (the "Due
Diligence Period") in which to evaluate the feasibility of purchasing the
Project.  During the Due Diligence Period and at all times throughout the
Contract Period, Seller shall, upon telephonic notice from Buyer not less
(but not significantly more than) twenty-four (24) hours prior to requested
entry, permit Buyer to enter the Property at all reasonable times, for the
purposes of conducting, at Buyer's sole cost and expense, such inspections,
studies and tests as Buyer may deem appropriate.  Upon Buyer's request,
Seller shall reasonably make available, at a mutually agreeable time at the
Property, to the extent Seller or the property manager has in its
possession or control, copies of the Property's financial books and
records, leases, service and management agreements, plans and
specifications, "as-built" surveys, permits, and engineering and
environmental reports except that Seller shall have no obligation to make
available any appraisals or documents subject to attorney-client privilege
(unless such documents specifically relate to the Project's current
physical condition or current operations).  At least twenty-four (24) hours


<PAGE>


prior to taking any samples relating to any environmental testing at or
related to the Project, Buyer shall notify Seller in writing of its intent
to take such samples and Buyer shall afford Seller and its consultants an
opportunity to take so-called "split samples" or duplicate samples of
whatever material or substance is being sampled by Buyer.  The incremental
cost of any such "split samples" shall be borne by Seller.  Buyer shall at
all times conduct its inspections, studies and tests in a manner so as to
not cause damage, loss, cost or expense to Seller or the Project, and to
not cause any unreasonable interference with Tenants, and Buyer shall
indemnify, defend, and hold Seller and the Project harmless from and
against any such damage, loss, lien, cost or expense related to such
inspections, studies and tests conducted by Buyer.  Buyer shall carry, in
commercially reasonable amounts, comprehensive general liability and such
other insurance reasonably necessary to insure Seller, as an additional
insured, and Buyer, and their respective contractors, employees and agents,
from any and all loss, damage, injury or expense caused by or resulting
from Buyer's inspections, studies and tests and if requested by Seller,
Buyer shall provide to Seller, prior to entry to the Property, with
certificates evidencing such insurance in form reasonably satisfactory to
Seller.  Unless Buyer obtains Seller's prior written consent, which shall
not be unreasonably withheld, conditioned or delayed, Buyer shall not make
any intrusive physical testing (environmental, structural or otherwise) at
the Project (such as soil borings or the like).  In the event that Seller
consents to such intrusive physical testing, Buyer shall, upon completion
of its testing, return the Project to its prior condition and repair any
damage caused by such testing.  At Seller's sole expense, Seller shall have
the right, as a condition to granting its consent hereunder, to cause a
representative of Seller and/or an engineer or other consultant to be
present at all inspections, reviews, examinations and testing conducted by
Buyer pursuant to this Section 9(a).  During the Due Diligence Period,
Buyer, prior to authorizing final written reports, shall afford Seller
three business days to review the then current draft of any written reports
commissioned by Buyer relating to environmental, physical or financial
matters affecting the Project which reports contain information materially
inconsistent with any written information theretofore made available by
Seller to Buyer.  Nothing herein contained shall be deemed to obligate
Buyer to obtain any written report or audit.  Buyer shall promptly deliver
to Seller, within fifteen (15) days after Buyer's receipt thereof, true and
complete copies of any final written reports commissioned prior to the
Closing relating to the Project, including, without limitation, any reports
relating to physical or environmental inspections and any engineering or
financial reports, prepared for or on behalf of Buyer by any third party.
Buyer shall keep all information or data received or discovered in
connection with any of the inspections, reviews or examinations strictly
confidential; provided, however, that Buyer shall have the right to
disclose such information to Buyer's attorneys, accountants and prospective
financing sources (collectively, "Buyer's Contacts") who reasonably need to
know such information and be informed of Buyer's determinations hereunder.
If any such information is disclosed to Buyer's Contacts, such Buyer's
Contacts shall, in turn, be required by Buyer in writing to keep such
information confidential.  This provision shall survive the Closing or the
sooner termination of this Agreement.

                 (b)  Buyer acknowledges that prior to the execution and
delivery of this Agreement, Buyer has received a Certificate and Report of
Title from NYLS and ordered the Survey.  On the Closing Date, Seller shall
remove, discharge or insure over any lien or encumbrance on the Project
which is not a Permitted Exception (a "Title Defect"), provided, however,
that Seller shall not be obligated to expend any funds or incur any
obligations to remove, discharge or insure over such Title Defect(s) in
excess of in the aggregate:

           (i)   Three Million Dollars ($3,000,000) with respect to a
monetary Title Defect of a liquidated nature that is readily ascertainable;



<PAGE>


           (ii)  One Million Dollars ($1,000,000) with respect to all
other Title Defects;

unless in the case of (i) or (ii) above, the creation of the Title Defect
was the result of a wilful and intentional act of Seller (but not of its
agents or third-party property manager) occurring after the date of this
Agreement (a "Wilful Defect") in which case

           (iii) if the Wilful Defect is of a monetary nature and the
damages are liquidated and readily ascertainable, Seller shall be obligated
to expend funds or incur obligations up to, but not exceeding, in the
aggregate an amount equal to the net proceeds of sale which would otherwise
be due Seller hereunder but for such Wilful Defect; and

           (iv)  if the Wilful Defect is of any other nature, Seller shall
not be obligated to expend any funds or incur any obligations in excess of
in the aggregate Six Million Dollars ($6,000,000); and


Seller may use any proceeds of the sale to remove, discharge, insure over
or otherwise satisfy (at Closing) any Title Defects and shall use the
proceeds of sale to cure any Title Defect described under clause (i) above
which is monetary in nature and readily ascertainable and under clause
(iii), in each case subject to the applicable limitation.

     Notwithstanding anything to the contrary contained in Section 6.2(c)
or Section 25, if, on the Closing Date, the Title Insurer fails to deliver
the Title Policy subject to no Title Defects, Buyer shall, as its sole and
exclusive remedy with respect to such failure, either (i) accept title to
the Project subject to such Title Defects and receive at Closing a credit
against the Purchase Price in the amount agreed upon by the parties or if
the parties cannot agree on the amount of such credit, Buyer shall pay the
Purchase Price without offset or reduction on account of such Title Defect
and may receive a refund after Closing to the extent provided herein, or
(ii) terminate this Agreement by written notice to Seller, in which event
the Deposit, together with all accrued interest thereon, shall be returned
to Buyer, any documents or other information theretofore delivered to Buyer
shall be returned to Seller and thereafter neither party shall have any
further rights or obligations hereunder, except as provided in Sections
9(a), 13 and 26.  If the parties cannot agree on the amount of the credit
due Purchaser on account of the Title Defect, then the parties shall
reasonably estimate the damages to Buyer resulting from a Title Defect
(subject to the limitations provided herein), and an amount equal to such
estimate shall be deposited in the escrow provided in Section 30(b) (the
"Section 9 Deposit") and the Buyer shall be entitled to a refund after
Closing in the amount of damages, if any, suffered by Buyer on account of
such Title Defect which shall in any event not exceed the Section 9
Deposit.  Subject to the foregoing, if the parties are unable to reach
agreement as to resulting damages or any such estimate, each party shall
estimate in good faith the amount of such damages (not to exceed the
applicable limitations set forth herein) and notify the other party in
writing of such estimated amount prior to the Closing.  Seller shall
deposit an amount equal to Buyer's estimate (such estimate not to exceed
the applicable limitations set forth herein), less out of pocket expenses
reasonably substantiated by Seller as theretofore expended by Seller after
the date of the relevant notice of Title Defect but prior to Closing in
bona fide attempts to cure the Title Defect.  Buyer's estimate under this
Section 9(b) shall not include any amounts included in Buyer's estimate
under Section 6.2(c).  With respect to any Title Defect (other than a
Wilful Defect) as to which Seller did not have notice at least ten business
days prior to the Closing Date (a "New Exception"), Seller shall be
entitled to a reasonable adjournment of the Closing Date provided for
herein (which adjournment period shall not exceed thirty (30) days) during
which to remove or cure any such New Exception.



<PAGE>


                 (c)  In addition to Buyer's termination rights under
Section 9(b) or elsewhere in this Agreement, Buyer shall have the right to
terminate this Agreement (but only any time up to and including the last
day of the Due Diligence Period) by delivering written notice of
termination to Seller in the manner set forth in Section 14, except that
Buyer may deliver such notice by facsimile transmission to the FAX numbers
set forth hereinbelow (and such notice shall be deemed given on the date
set forth in Section 14 below), provided that on the same date of such
facsimile transmission Buyer shall also send such written notice as
provided in Section 14.  In such event, the Deposit plus all interest
accrued thereon, if any, shall be returned to Buyer and neither party shall
have any further rights or obligations hereunder, except as set forth under
Sections 9(a), 13, 26 and 34.  If Buyer fails to deliver such notice of
termination on or before the last day of the Due Diligence Period, then
Buyer shall be obligated to close this transaction as provided herein,
subject to the other terms and conditions hereof.

                 (d)  Notwithstanding anything to contrary set forth
herein, by written notice (the "Extension Notice") delivered to Seller no
later than the last day of the initial Due Diligence Period, Buyer shall
have the right to extend the Due Diligence Period ("Extended Due Diligence
Period") if a bona fide letter is attached to such Extension Notice from
any of Buyer's third party consultants for physical (including, without
limitation, the matter which is the subject of the Declaration and Grant of
Access Easement dated as of November 7, 1994 (recorded on November 13, 1984
in Reel 847, page 387) and the "plaque" relating to accessibility attached
to the loading dock wall of the Project), environmental or financial
matters signed by such party which states (i) that such consultant needs
additional time to conduct further inspections or investigations based on
the progress or results of its investigations to date (other than with
respect to financial matters) or that, with respect to financial matters
(other than matters relating to market conditions), such consultant needs
additional time (based on the progress or results of its review to date) to
complete its review of Seller's books and records with respect to the
operation of the Project for the last three full calendar years (and the
current year to date) and the financial performance of the Project during
such period, with no requirement that an "opinion" or similar written
reports be issued by such financial consultant in connection with such
review of Seller's books and records, and (ii) sets forth the categories
(e.g. physical, environmental and/or financial) which require further
investigation or completion (the "Categories").  Buyer warrants and
represents that the consultant referred to in the foregoing clause will be
promptly engaged by Buyer after the date of this Agreement and will be
instructed to exercise due diligence to complete its tasks.  The Extended
Due Diligence Period shall expire upon that date which is thirty (30) days
after the last day of the initial Due Diligence Period.  If Buyer exercises
its right to extend the Due Diligence Period in accordance with the terms
hereof, the Extended Due Diligence Period shall for all purposes be and be
deemed a part of the Due Diligence Period hereunder, provided, however,
that (i) in no event shall the Closing Period be extended by reason of the
Extended Due Diligence Period and (ii) Buyer's right to terminate after the
expiration of initial 30 day Due Diligence Period may be exercised only if
matters within the Categories are not satisfactory to Buyer in its sole
discretion; all other matters being waived by Buyer as of the expiration of
the initial Due Diligence Period, without limitation of any other right of
Buyer to terminate or obtain credits or indemnities as expressly provided
for herein.  The Extension Notice shall be delivered to Seller in the
manner set forth in Section 14, except that Buyer may deliver such notice
by facsimile transmission to the FAX numbers set forth hereinbelow (and
such notice shall be deemed given on the date set forth in Section 14
below), provided that on the same date of such facsimile transmission Buyer
shall also send such written notice as provided in Section 14.

     10.   Damage or Destruction.  Prior to the Closing Date, the risk of
loss of or damage to the Project by reason of any insured or uninsured
casualty shall be borne by Seller as follows:

                 (a)  In the event of any damage to or destruction of the
Project or any portion thereof (notice of which shall be given to Buyer by
Seller promptly following its occurrence) prior to the Closing Date, which
damage or destruction is covered by insurance and can, in Seller's
reasonable judgment, be repaired or replaced for a cost not to exceed
$10,000,000, then Buyer shall have the option to either (i) cause Seller to
commence to repair or replace such damage to or destruction of the Project
or the applicable portion thereof or (ii) proceed to Closing and accept the
Project as it is together with the insurance proceeds, if any, and the
right to receive same, with a credit against the Purchase Price equal to
the amount of the deductible under Seller's insurance policies.  If the
cost of such repair or replacement exceeds $10,000,000, Buyer may, at its
option, by notice given within thirty (30) days after the date that the
cost to repair or replace such damage is determined and the parties are
notified of the same, unilaterally terminate this Agreement, in which event
this Agreement shall terminate immediately, the Deposit and all accrued
interest thereon shall be returned to Buyer and thereafter neither party
shall have any further rights or obligations hereunder, except as set forth
in Sections 9(a), 13, 26 and 34.  If Buyer does not terminate this
Agreement as provided in this Section 10(a), the parties shall be deemed to
have elected to continue this Agreement and Seller shall assign to Buyer at
the Closing any insurance proceeds payable in respect of such casualty; or

                 (b)  In the event of any uninsured damage to or
destruction of the Project or any portion thereof (notice of which shall be
given to Buyer by Seller promptly following its occurrence) prior to the
Closing Date, which damage or destruction can, in Seller's reasonable
judgment based upon the written advice of engineers and/or architect, be
repaired or replaced for a cost not to exceed $2,000,000, at Buyer's
option, Seller shall either (i) commence to repair or replace such damage
to or destruction of the Project or the applicable portion thereof or (ii)
proceed to Closing, whereupon Buyer will accept the Project as it is
together with a reduction of the Purchase Price in the amount of the
engineer/architect's estimate of the cost to replace the damaged portion of
the Project.  If the cost of such repair or replacement exceeds $2,000,000,
then Seller may, at its option, by notice to Buyer given within thirty (30)
days after the date that the cost to repair or replace such damage is
determined, unilaterally terminate this Agreement, in which event this
Agreement shall terminate immediately, the Deposit and all accrued interest
thereon shall be returned to Buyer and thereafter neither party shall have
any further rights or obligations hereunder, except as set forth in
Sections 9(a), 13, 26 and 34.  If Seller does not elect to terminate this
Agreement as provided in this Section 10(b), then this Agreement shall
continue between Buyer and Seller and Buyer shall receive a credit, at
Closing, in an amount equal to the estimated cost of such restoration as
reasonably determined by an independent architect selected by Seller.

     The parties understand and agree that the provisions of this
Section 10 shall govern and supersede the provisions of Section 5-1311 of
the General Obligation Law of the State of New York.

     11.   Eminent Domain.  In the event of any threatened in writing or
commenced or consummated proceedings in eminent domain (notice of which
shall be given to Buyer by Seller promptly) respecting all or substantially
all of the Project, Buyer may, at its option, by notice to Seller given
thirty (30) days after Buyer is notified of such actual or possible
proceedings, unilaterally terminate this Agreement, in which event the
Deposit together with accrued interest thereon, if any, shall be returned
to Buyer and thereafter neither party shall have any further rights or
obligations hereunder, except as set forth in Sections 9(a), 13, 19, 26 and


<PAGE>


34. If Buyer fails to do so, Buyer shall be deemed to have elected to
continue this Agreement, in which event Seller shall, at the Closing,
assign to Buyer its entire right, title and interest in and to any
condemnation award (and Seller shall pay to Buyer any such compensation and
damages already received) and Buyer shall have the sole right during the
Contract Period to negotiate and otherwise deal with the condemning
authority in respect of such matter. The parties understand and agree that
the provisions of this Section 11 shall govern and supersede the provisions
of Section 5-1311 of the General Obligation Law of the State of New York.

     12.   Conditions to Closing.

           12.1. Buyer's Conditions.  Buyer's obligation to purchase the
Project and pay the Purchase Price is expressly conditioned upon the
following (unless waived by Buyer), and absent satisfaction of same at the

with the transactions contemplated by this Agreement, except for the
HIGroup, LLC (the "Broker").  Seller shall be responsible for the payment
of any fees, commissions and/or costs payable to Broker in accordance with
a separate agreement between Seller and Broker.  Subject to the foregoing,
each party hereby indemnifies and agrees to defend and hold the other and
its affiliates and the principals, officers and directors of each thereof
harmless from and against any loss, cost, damage, liability or expense
(including, without limitation, reasonable attorneys' fees and expenses)
arising out of or in connection with the incorrectness of such
representation and warranty.  This provision shall survive the Closing.

     15.   Counterparts.  This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which taken together
shall constitute but one and the same instrument.

     16.   Governing Law.  This Agreement shall be governed by,

Agreement shall be brought exclusively in the Federal courts, or in the
absence of Federal jurisdiction in state courts, in the City of New York,
New York. Seller and Buyer irrevocably and unconditionally submit to the
jurisdiction of such courts and agree to take any and all future action
necessary to submit to the jurisdiction of such courts. Seller and Buyer
irrevocably waive any objection that they now have or hereafter may have to

waived, except by written instrument signed by the party to be charged or
by its agent duly authorized in writing or as otherwise expressly permitted
herein.  The parties do not intend to confer any benefit hereunder on any
person, firm or corporation other than the parties hereto.  This provision
shall survive the Closing.

     19.   Non-Waiver of Rights.  No failure or delay of either party in
the exercise of any right given to such party hereunder shall constitute a
waiver thereof unless the time specified herein for exercise of such right
has expired, nor shall any single or partial exercise of any right preclude
other or further exercise thereof or of any other right.  The waiver of any
breach hereunder shall not be deemed to be a waiver of any other or any
subsequent breach hereof.

     20.   Titles and Headings.  Titles and headings of Articles and
Sections of this Agreement are for convenience of reference only and shall
not affect the construction of any provision of this Agreement.

     21.   Exhibits and Schedules.  Each of the Exhibits and Schedules
referred to herein and attached hereto is an integral part of this
Agreement and is incorporated herein by this reference.



<PAGE>


     22.   Pronouns; Joint and Several Liability.  All pronouns and any
variation thereof shall be deemed to refer to the masculine, feminine or
neuter, singular of plural, as the identity of the parties may require.  If
the Buyer consists of two or more parties, the liability of such parties
shall be joint and several.

     23.   Further Assurances.  Seller and Buyer each agrees to do such
further acts and things and to execute and deliver such additional
agreements and instruments as the other may reasonably require to
consummate, evidence or confirm the sale or any other agreement contained
herein in the manner contemplated hereby.

     24.   Assignment.  Buyer may not, without Seller's prior written
consent, assign this Agreement or any interest hereunder to any person or
entity except an Affiliate, as defined below; provided, that any such
Affiliate shall expressly assume, in writing, the covenants, undertakings,
warranties, representations and all other obligations of Buyer under this
Agreement, whether before or after Closing and Buyer shall not be released
from any of its obligations hereunder. As used herein, "Affiliate" means
(i) Werner Otto and/or his direct descendants, (ii) trusts for the benefit
of any person(s) described in clause (i), and (iii) entities which one or
more of the persons or entities described in clauses (i) and (ii) control.
As used herein, "descendants" shall include legally adopted persons; and
"control" shall mean the ability to direct the management and operation of
the entity and the ability of another party  to approve major decisions
shall not be deemed a lack of control.  Notwithstanding the foregoing, at
Closing, Buyer may designate another person or entity (the "Designated
Grantee") to take title to the Project, provided that in consideration
thereof, such person or entity shall deliver at Closing a guaranty in form
reasonably satisfactory to Seller pursuant to which the Designated Grantee
shall unconditionally and irrevocably and in favor of the Seller (a)
guarantee the performance by the Buyer of the covenants and agreements of,
and the truth and accuracy of the representations and warranties made by,
the Buyer in the Agreement and in all related closing documents, and adopt
such covenants, agreements, representations and warranties as though they
had been made by the Designated Grantee directly and (b) agree to
indemnify, defend and hold harmless the Seller from and against any claims,
damages, costs, expenses (including reasonable attorneys' fees and
expenses, including expert witnesses and consultants, if any), liability or
losses suffered as a result of any inaccuracy or breach of the
representations and warranties, or breach of any covenant or agreement,
made by the Buyer in the Agreement or in any related closing document.  The
Designated Grantee shall agree that the Seller may enforce the foregoing
guaranty and indemnification obligation against it without first making
demand or taking action against the Buyer and such guaranty shall be
construed as a guaranty of performance or payment, not as a guaranty of
collection.  The Designated Grantee shall not be deemed an assignee of
Buyer's rights under the Agreement and Buyer shall not be released from any
of its obligations hereunder.  The Designated Grantee shall not be a party
to the escrow agreement established pursuant to Section 30(b).

     25.   Remedies Upon Default.

                 (a)  Should Buyer fail to purchase the Project in
accordance with the terms hereof (a "Buyer Default"), then Seller may on
written notice to Buyer terminate this Agreement and retain the Deposit as
liquidated damages to Seller for such breach by Buyer as Seller's sole and
exclusive remedy.  Seller and Buyer agree that a determination of actual
damages under these circumstances is not reasonably possible and that the
aforesaid sum is a reasonable amount for liquidated damages under the
circumstances existing at the time this Agreement is executed and
delivered.



<PAGE>


                 (b)  Should Seller fail to sell the Project to Buyer in
accordance with the terms hereof, then Buyer may, as its sole and exclusive
remedy (subject to Sections 6.2(c) and 9(b)), (1) by written notice to
Seller, terminate this Agreement and receive the return of the Deposit with
all interest accrued thereon, if any, and neither party shall have any
further rights or obligations hereunder, except as set forth under
Sections 9(a), 13, 26 and 29 or (2) no later than 30 days after what the
Closing Date would have been if Seller had not defaulted hereunder, sue for
specific performance.

     26.   Confidentiality.

                 (a)  Buyer agrees that they shall treat and hold as
confidential all information relating to the Project received from or on
behalf of Seller.  Buyer agrees that Buyer will keep all such information
confidential, and will (a) not disclose or permit the disclosure of any
such information to any person or entity unless such member has a bona fide
business purpose in connection with the transaction contemplated hereby;
(b) not use or permit the use of such information for any purpose other
than evaluating the transaction contemplated hereby or enforcing rights and
remedies in connection with this Agreement; and (c) be responsible for any
disclosure or use in violation of the terms hereof by Buyer or any person
or entity which obtains, directly or indirectly, any such information from
Buyer.

                 (b)  If this Agreement is terminated and the Closing
does not occur for any reason, then upon such termination and upon the
return of the Deposit to Buyer, Buyer shall deliver to Seller any documents
and materials related to the Project previously delivered to Buyer by
Seller.  Buyer hereby acknowledges and agrees that the terms of the
confidentiality agreement signed by Buyer (the "Confidentiality Agreement")
are hereby incorporated into this Agreement by reference in their entirety
as if fully set forth herein and Buyer hereby re-affirms Buyer's obligation
to abide by and comply with the terms of the Confidentiality Agreement.

                 (c)  At no time shall either Seller or Buyer issue any
press release disclosing this Agreement or any of the terms, provisions or
other information contained herein, unless mutually agreed to between
Seller and Buyer.

     27.   Survival of Representations and Warranties.  All
representations and warranties of Seller shall survive until September 15,
2000 (the "Warranty Period").

     28.   WAIVER OF JURY TRIAL.  THE PARTIES HERETO HEREBY EXPRESSLY
WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF
ACTION (a) ARISING UNDER THIS AGREEMENT OR THE OTHER AGREEMENTS, INCLUDING,
WITHOUT LIMITATION, ANY PRESENT OR FUTURE MODIFICATION THEREOF OR (b) IN
ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE
PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT OR THE OTHER
AGREEMENTS (AS NOW OR HEREAFTER MODIFIED) OR ANY OTHER INSTRUMENT, DOCUMENT
OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE
TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION IS NOW EXISTING OR HEREAFTER ARISING, AND
WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND THE PARTIES HEREBY
AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION
SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS
AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH
ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE
WAIVER OF ANY RIGHT THEY MIGHT OTHERWISE HAVE TO TRIAL BY JURY.

     29.   Recordation of Agreement.  Neither Seller nor Buyer may record
this Agreement or any memorandum thereof.  The provisions of this
Section 29 shall survive the termination of this Agreement.



<PAGE>


     30.   Limitation of Liability.

                 (a)  Notwithstanding anything to the contrary herein, if
the Closing hereunder shall have occurred (and Buyer shall not have waived,
relinquished or released any applicable rights in further limitation),
except for and to the extent of Seller's obligations under Section 6.2(c)
or Section 9(b) with respect to a Known Breach or Title Defect,
respectively, that expressly survives Closing (subject to the limitations
provided therein), the aggregate liability of Seller arising pursuant to or
in connection with the representations, warranties, indemnifications,
covenants or other obligations of Seller under this Agreement (or any
document executed or delivered in connection herewith or in connection with
the Closing)(collectively, "Seller's Obligations") shall not exceed Five
Million Dollars ($5,000,000) (the "Maximum Amount"), provided that the
Seller shall not be liable for a breach of any of Seller's Obligations
unless and until the aggregate amount of damages suffered by Buyer as a
result of a breach of one of more of Seller's Obligations exceeds $125,000
(the "Basket") and thereafter only for the excess over such Basket, such
excess not to exceed the Maximum Amount.

                 (b)  At Closing, Seller, Buyer and Escrow Agent shall
enter into a mutually satisfactory escrow agreement pursuant to which
Seller shall deposit $5,000,000 (the "Post-Closing Deposit") with Escrow
Agent and may deposit additional funds pursuant to Section 6.2 (c) hereof
(and defined therein as the Section 6.2 Deposit) or Section 9(b) hereof
(and defined therein as the Section 9 Deposit). The Post-Closing Deposit
and the Section 6.2 Deposit, if any, and the Section 9 Deposit, if any, are
sometimes herein collectively called the "Closing Deposits"). The Closing
Deposits shall be invested solely in short-term United States Treasury
securities or other insured, low-risk, short-term securities mutually
agreed upon.  Interest accruing on such Closing Deposits shall be promptly
released from the escrow and paid monthly to Seller.  Buyer acknowledges
that Seller may assign its rights to the Closing Deposits to its partners.
Escrow Agent shall hold the Closing Deposits in an interest-bearing
account. In connection therewith:

                      (i)   The Post-Closing Deposit shall be released
(i) to Seller upon the expiration of the Warranty Period, in the event and
to the extent that the Post-Closing Deposit exceeds the amount of claims
having been asserted in writing by Buyer against Seller post-closing under
Section 30(a) hereof less the Basket ("Post-Closing Claims") prior to the
expiration of the Warranty Period, and (ii) to Buyer, with respect to Post-
Closing Claims asserted in writing prior to the expiration of the Warranty
Period, an amount (not to exceed the Post-Closing Deposit) as agreed upon
by Seller and Buyer or to which Buyer is entitled pursuant to the
arbitration provided for herein, with any balance to Seller.

                      (ii)  The Section 6.2 Deposit shall be released as
agreed upon by Seller and Buyer or pursuant to the arbitration provided for
herein.

                      (iii) The Section 9 Deposit shall be released as
agreed upon by Seller and Buyer or pursuant to the arbitration provided for
herein.

                 (c)  Except as specifically set forth hereafter, no
constituent partner in or agent of Seller, nor any partner, member,
trustee, director, officer, employee, beneficiary, shareholder,
participant, representative, advisor or agent of any entity that is or
becomes a constituent partner in Seller (hereafter, "Indirect Entities")
shall have any personal liability, directly or indirectly, under or in
connection with this Agreement or any agreement made or entered into 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


<PAGE>


hereafter, and Buyer and its successors and assigns and, without
limitation, all other persons and entities, shall look solely to Seller's
assets for the 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 Seller ( or in any other constituent partner of
Seller) to restore a negative capital account or to contribute capital to
Seller (or to any other constituent partner of Seller), shall at any time
be deemed to be the property or an asset of Seller or any such other
constituent partner (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 of partner's obligation to restore or
contribute.

                 (d)  The provisions of this Section 30 shall survive the
Closing.

     31.   Tax Free Exchange.  Notwithstanding anything to the contrary
set forth herein, Buyer may take such steps as Buyer shall deem necessary
or desirable to qualify the purchase of the Real Property under Section
1031 of the Internal Revenue Code of 1986, as amended (a "1031
Transaction"), including the use of, and/or assignment of this Agreement
to, one or more "qualified intermediaries" within the meaning of Treas.
Regs. ' 1.1031(k)-l(g)(4), or the use of any other multiparty arrangement
described in Treas. Regs. ' 1.1031(k)-l(g).  Seller shall use reasonable
efforts to cooperate (which cooperation shall be at Buyer's sole cost and
expense) in so affecting a 1031 Transaction, if so desired by Buyer,
provided that such structuring shall not adversely affect Seller's rights
or obligations hereunder.  In providing such assistance, Seller shall
execute such documents as may be reasonably required by Buyer to effectuate
such exchange ("Exchange Documents") and otherwise comply with the
provisions of this Article 31, provided that the 1031 Transaction and the
Exchange Documents shall not (a) require Seller to execute any contract,
make any commitment, or incur any obligations, contingent or otherwise, to
third parties, (b) cause Seller to be liable or potentially liable for any
environmental conditions affecting property, (c) delay the Closing, (d)
include Seller's acquiring title to any property or otherwise becoming
involved in a transaction with a third party, and (e) otherwise be contrary
to or inconsistent with the terms of this Agreement.  Any Exchange Document
that Buyer shall request Seller to execute shall be prepared and submitted
to Seller at least seven (7) business days prior to the date that Seller's
execution thereof is requested.  Seller shall execute any such Exchange
Document only if it conforms in all respects to the provisions of this
Agreement relating to an Exchange Document.  In no event shall Seller be
required, by reason of the 1031 Transaction, the execution of any Exchange
Document or otherwise, to make any payment or assume or incur any
liability, obligation, cost or expense which would be in addition to any
obligation expressly assumed by Seller under this Agreement if the Property
were transferred directly to Buyer.  Neither the 1031 Transaction nor any
Exchange Document shall subject either Seller, its respective partners or
the heirs, successors and assigns thereof, to any personal liability or
obligations.  Seller shall have no obligation to transfer the Property
pursuant to an Exchange Document until all conditions to the transfer of
the Property set forth in this Agreement (including, without limitation,
payment of the Purchase Price to Seller and assumption of all liabilities
by Buyer) have been satisfied.  Buyer acknowledges that Seller is agreeing
to cooperate with respect to the 1031 Transaction and enter into Exchange
Documents solely as an accommodation to Buyer and that it is not intended
that Seller will incur any costs or liabilities with respect to the 1031
Transaction in carrying out its obligations pursuant to this Agreement,
other than those which would have been incurred if the Property had been
transferred directly to Buyer.  Accordingly, Buyer hereby agrees to
indemnify, defend and hold Seller, its respective partners and the heirs,


<PAGE>


successors and assigns thereof, harmless from, against and in respect of,
and shall on demand reimburse Seller, its respective partners and the
heirs, successors and assigns thereof for, any and all loss, liability,
damage or expense, including but not limited to attorneys fees and costs of
litigation, arising out of or in any way connected with the 1031
Transaction or any Exchange Document which would not have been incurred if
the Property had been transferred directly to Buyer.  Buyer shall be
responsible for any and all professional fees (including, but not limited
to, attorneys' fees and costs of disputes) incurred by Seller in reviewing
the Exchange Documents or otherwise pursuant to this Section 31.

     32.   Indemnity by Seller.  Seller shall indemnify, defend, and hold
Buyer harmless from and against any and all loss, cost, expense (including
reasonable attorneys' fees and disbursements), damage or liability arising
out of, directly or indirectly, (a) claims of whatever nature (including,
without limitation, bodily injury, wrongful death, or property damage)
against Buyer or the Project based on causes of action which arose, accrued
or relate to facts occurring prior to the Closing, not caused by Buyer, its
agents, contractors and other representatives (b) claims by tenants,
employees, contractors under the Service Contracts, utility companies, and
the holder of any mortgage on the Project  (or any portion thereof), with
respect to matters that occurred or obligations which accrued prior to the
Closing, and (c) claims resulting from Seller's failure to comply with any
applicable provisions of the New York Bulk Sales Act.  The provisions of
this Section 32 shall survive the Closing.

     33.   Indemnity by Buyer.  Buyer shall indemnify, defend, and hold
Seller harmless from and against any and all loss, cost, expense (including
reasonable attorneys' fees and disbursements), damage or liability arising
out of, directly or indirectly, (a) claims of whatever nature (including,
without limitation, bodily injury, wrongful death, or property damage)
against Seller or the Project based on causes of action which arose,
accrued or relate to facts occurring after the Closing not caused by
Seller, its agents, contractors and other representatives, (b) claims by
tenants, employees, contractors under the Service Contracts, utility
companies, and the holder of any mortgage on the Project  (or any portion
thereof), with respect to matters that occurred or obligations which
accrued after the Closing, and (c) claims resulting from Buyer's failure to
comply with any applicable union contracts affecting the Project after the
Closing, provided Seller shall be and remain responsible for compliance
with any such union contracts for all periods prior to the Closing Date.
The provisions of this Section 33 shall survive the Closing.

     34.   Attorneys' Fees.  Should either party institute any action or
proceeding to enforce this Agreement or any provision hereof, or for
damages by reason of any alleged breach of this Agreement or of any
provision hereof, or for a declaration of rights hereunder, the prevailing
party in any such action or proceeding shall be entitled to receive from
the other party all costs and expenses, including reasonable attorneys'
fees, incurred by the prevailing party in connection with such action or
proceeding.

     35.   Arbitration.

                 (a)  All disputes arising from or related to Section
6.2(c), Section 9(b) or Section 30 (including Post-Closing Claims) shall be
finally determined by arbitration conducted in the City and County of New
York, before and, except as herein provided, in accordance with the
Expedited Procedures and Arbitration Rules for the Real Estate Industry
then adopted by the American Arbitration Association ("AAA") or any
successor body of similar function, and judgment upon the award rendered
may be entered in any court having jurisdiction thereof. Seller and Buyer
shall sign all documents and do all other things necessary to submit any
such matter to arbitration and agree to, and hereby do, waive any and all
rights they or either of them may at any time have to revoke their
agreement hereunder to submit to arbitration and to abide by the decision
rendered thereunder.  The arbitrators shall have no power to vary or modify


<PAGE>


any of the provisions of this Agreement; their jurisdiction is limited
accordingly.  Each arbitrator appointed pursuant to the terms hereof shall
have at least ten (10) years experience in commercial real estate.

                 (b) The provisions of this Subsection (b) shall apply to
all disputes arising from or related to the Post-Closing Deposit and Post-
Closing Claims.  Within five (5) days following written demand for
arbitration by either party served upon the other (which may, at the
initiating party's option, be simultaneously filed with AAA or at any time
thereafter), each party shall appoint a person as arbitrator on its behalf
and give notice thereof to the other party.  The arbitrators thus appointed
shall make their determinations as provided herein.  The arbitrators shall
state their determinations in writing within twenty (20) days of their
appointment and simultaneously give notice thereof to each other and to
Buyer and Seller.  Such two (2) arbitrators shall have ten (10) days after
the expiration of the foregoing 20-day period to confer with the other and
to attempt to reach agreement as to a final determination.  If such two (2)
arbitrators shall concur as to the determination, such concurrence shall be
final and binding upon Buyer and Seller and judgment upon the award may be
entered in any court having jurisdiction.  If such two (2) arbitrators
shall fail to concur, then such two (2) arbitrators shall appoint a third
arbitrator within five (5) days of the expiration of the foregoing 10-day
period.  If the two (2) arbitrators shall fail to agree upon the
appointment of such third arbitrator within such 5-day period, then the AAA
shall appoint such third arbitrator.  The third arbitrator shall conduct
such hearings and investigations as he/she may deem appropriate and shall,
within thirty (30) days after the date of his/her appointment choose one
(1) of the determinations (as the same may be modified or amended at any
time prior the appointment of the third arbitration or thereafter upon
leave of the third arbitrator) of the two (2) arbitrators originally
selected by the parties, and that choice by the third arbitrator shall be
binding upon Buyer and Seller and judgment upon the award may be entered in
any court having jurisdiction.  Each party shall pay its own counsel fees
and expenses, including the expenses and fees of any arbitrator selected by
it in accordance with the provisions hereof, and the parties shall share
all other expenses and fees of any such arbitration.  If a party who shall
have the right pursuant to the foregoing to appoint an arbitrator fails or
neglects to do so within the stated time period, then and in such event,
the AAA shall appoint such arbitrator.

                 (c)  The provisions of this subsection (c) shall apply
to disputes arising under or related to Section 6.2(c) or Section 9(b).
Within ten (10) days after Closing, the parties shall either agree upon a
single arbitrator or, absent such agreement within such time, the AAA shall
appoint such single arbitrator.  Such arbitrator shall conduct such
hearings and investigations as he/she may deem appropriate and shall,
within ten (10) business days after the date of his/her appointment, choose
either Seller's or Buyer's original estimate which was used in determining
the Closing Deposits made pursuant to Section 6.2(c) or Section 9(b), and
that choice shall be binding upon Buyer and Seller and shall determine the
amounts, if any, to be paid to Buyer from the applicable Closing Deposits.
After payments of such amounts to the Buyer, the balance shall be promptly
paid to Seller.

     36.   Buyer's Financing.  Until such time as the Closing Deposits
have been released from the escrow provided for herein, Buyer shall not
voluntarily encumber or permit liens or mortgages against the Project in an
aggregate amount exceeding One Hundred Thirty Nine Million Dollars
($139,000,000).
