ITEM 2.  ACQUISITION OF ASSETS

     On April 25, 2001, Boston Properties Limited Partnership, the operating
partnership subsidiary (together with its direct and indirect wholly-owned
subsidiaries, "BPLP") of Boston Properties, Inc. (the "Company"), completed the
acquisition of the 59-story, 1.6 million square foot Citigroup Center in New
York City at a purchase price of approximately $725 million.  BPLP completed the
acquisition through a joint venture with affiliates of Allied Partners, a
private family-owned real estate investment company founded in 1993 (together
with its affiliates, "Allied").  The sellers were Dai-Ichi Life Investment
Properties, Inc and Citibank, N.A. pursuant to contracts that were assigned to
the joint venture as part of a series of transactions leading to the closing of
the acquisition. Allied invested $35 million in common equity in the joint
venture. BPLP invested the balance of approximately $195 million of equity
required to complete the transaction, with approximately $66.5 million in common
equity and the balance in preferred equity.

     Citigroup Center, the 59-story, 1.6 million square foot skyline building
known for its distinctive cantilevered structure and angled top, was built in
1977 and was designed by Hugh Stubbins & Associates and Emery Roth & Sons.  The
atrium, open-air plaza and office tower lobby were renovated in 1997.  The
property is 100% leased and the tenants include Citigroup, O'Melveny & Myers,
Kirkland & Ellis and AT Kearney, among other well-known tenants.  Citigroup
Center provides direct access to New York City's transit system through its
prime location atop a major subway station.

     The transaction was consummated through a newly-formed Delaware limited
liability company, of which BPLP is the managing member.  The total acquisition
cost of approximately $755 million, including purchase price, closing costs and
mortgage-recording taxes, was funded through a $525 million first mortgage
provided by an affiliate of Deutsche Bank and equity investments in the limited
liability company by BPLP and Allied.  Giving effect to the closing and all
related transactions, BPLP holds a $66.5 million Class A common equity interest
and a $128.5 million preferred equity interest in the limited liability company.
Allied as non-managing member holds a $35.0 million Class B common equity
interest.  In addition, BPLP and Allied hold residual membership interests equal
to 65.5% and 34.5%, respectively, in the joint venture.  BPLP funded its $195
million investment in common and preferred equity interests in the joint venture
through borrowings under its existing unsecured revolving line of credit and
available cash.

     The preferred equity and Class A common equity interests held by BPLP will
earn a cumulative compounding 10% priority return (the "BPLP Priority Return")
which, for a period up to 10 years after the closing, will be paid out of cash
flow or will accrue and be paid out of the proceeds of any capital transaction.
The Class B common equity interest held by Allied will earn no return for the
first 10 years. If any portion of the preferred equity interest remains
outstanding after the tenth anniversary of the closing, thereafter Allied's
Class B common equity interest will earn a cumulative compounding 10% return
(the "Allied Priority Return"), which will be payable out of cash flow or the
proceeds of any capital transaction before the BPLP Priority Return for the same
period and any accumulated unpaid portion of the BPLP Priority Return for the
first 10 years can be paid. During the first 10 years, BPLP's preferred equity
investment and any accumulated unpaid portion of the BPLP Priority Return will
be payable first out of the proceeds

                                       2


of any refinancing of the property and any additional refinancing proceeds will
be used to repay the Class A and Class B common equity investments
proportionately. After the tenth anniversary of the closing, refinancing
proceeds will be used first to pay the Allied Priority Return, then to pay the
BPLP Priority Return (including any accumulated unpaid amount accrued during the
first 10 years), then to repay BPLP's preferred investment, and finally to repay
the Class A and Class B common equity investments proportionately. Thereafter,
BPLP and Allied will share in cash flow and proceeds from any capital
transaction in proportion to their respective residual membership interests.

     In connection with the acquisition of Citigroup Center, BPLP has entered
into agreements with Allied that generally provide that, for a period of fifteen
years, BPLP may not sell or otherwise transfer the assets received in the
acquisition of Citigroup Center without the consent of Allied and will maintain
agreed upon levels of recourse or other indebtedness outstanding and available
to be guaranteed by Allied.  In addition, in connection with the transaction,
Allied acquired 26,821 common units of limited partnership of BPLP, valued at
approximately $1 million on the date of issuance (based on a price of $37.28 per
common unit, the average closing price of a share of common stock of the Company
during the ten trading days preceding the closing).  The common units may be
redeemed by the holder for cash equal to the then current value of a share of
common stock of the Company or, at the Company's election, for one share of
common stock of the Company.

         books and records of Seller (except to the extent relating to the
         operation of the Unit) maintained at any of Seller's offices, internal
         and external appraisals of the Unit and any other privileged or
         proprietary information not otherwise in the possession of Seller; and

                  (x)     all other intangible personal property owned by Seller
         or in which Seller otherwise has an interest and used solely in
         connection with or arising solely in connection with the business
         conducted on or from the Unit or any part thereof, including, if
         available, telephone exchange numbers, specifically excluding, however,
         any names or marks of Seller or any affiliates of Seller.

                                       12


Seller shall deliver or cause to be delivered to Purchaser at the Closing such
deeds, bills of sale, assignments or other transfer documents necessary to
transfer Seller's interest in and to all of the foregoing property to Purchaser
consistent with the terms of this Agreement.

         (f) Seller and Purchaser acknowledge and agree that the value of the
personal property that is included in the transaction contemplated by this
Agreement is DE MINIMIS and no part of the Purchase Price is allocable thereto.

         3.  INTENTIONALLY OMITTED.

         4.  STATUS OF TITLE; TITLE INSURANCE AND SURVEY COSTS.

         (a) The Unit shall be conveyed to Purchaser, subject only to (i) the
standard exceptions and provisions contained in the form of 1992 ALTA owner's
title insurance policy employed by the Title Insurer, (ii) those matters set
forth on SCHEDULE 4(a), (iii) any Title Exceptions that are created, allowed or
suffered to exist by the Board of Managers (subject to the provisions of the
second sentence of SECTION 4(b)), and (iv) any Title Exceptions that are
approved or waived by Purchaser in writing (collectively, the "PERMITTED
ENCUMBRANCES"). Mechanics liens and other liens or encumbrances related to
proposed or actual work with respect to the Unit on behalf of Seller or the
Board of Managers (as opposed to any tenant or occupant in its capacity as such)
shall not constitute Permitted Encumbrances. Seller shall use its good faith
commercially reasonable efforts to cause all open building permits with respect
to the Unit (other than those that are the responsibility of any tenant or other
occupant of the Unit) to be closed out on or before the Closing Date.
Notwithstanding the foregoing, if such permits (other than those that are the
responsibility of any tenant or occupant of the Unit) have not been closed out
on or before the Closing Date, Seller shall deliver an undertaking to Purchaser
at Closing to cause such open building permits to be closed out.

         (b) Seller shall not create or allow or suffer to exist any Title
Exception with respect to the Unit that is not a Permitted Encumbrance without
the consent of Purchaser. During the period prior to the Closing, Seller shall
(i) cause its representatives to the Board of Managers to approve Title
Exceptions affecting either the Unit or Unit Two only after obtaining the prior
consent of Purchaser, and (ii) use good faith reasonable efforts to cause
Citibank, N.A. to satisfy its obligations as seller with respect to the
creation, allowance or sufferance of title exceptions that may adversely affect
Unit Two pursuant to Section 4(b) of the Unit Two Contract. If on the Closing
Date, there are any Title Exceptions that are not Permitted Encumbrances,
Purchaser shall, to the extent necessary or required, cooperate with Seller in
removing such Title Exceptions or causing such Title Exceptions to be removed,
and Seller shall be obligated to pay, discharge and/or otherwise remove such
Title Exceptions (other than those created or allowed or suffered to exist by
Purchaser or the Board of Managers) or to cause any such Title Exceptions to be
removed irrespective of the cost therefor, and Purchaser shall have such rights
of action against Seller, at law or in equity, to cause Seller to convey title
to the Unit subject only to Permitted Encumbrances. Notwithstanding the
foregoing, Purchaser may elect to accept such title as Seller can convey,
notwithstanding the existence of Title Exceptions that are not Permitted
Encumbrances. In such event, this Agreement shall remain in effect and the
parties shall proceed to Closing, but Purchaser shall not be entitled to any
credit or allowance of

                                       13


any kind or any claim or right of action against Seller for damages or otherwise
by reason of the existence of any Title Exceptions which are not Permitted
Encumbrances.

         (c) The costs of examination of title (including all UCC, tax and other
searches) and title premiums for the issuance by the Title Insurer of policies
of title insurance insuring Purchaser's fee interest in the Unit, conforming to
the requirements of Purchaser (other than endorsements, if any, required to be
obtained by Seller pursuant to SECTION 4(b) to omit Title Exceptions that are
not Permitted Encumbrances from the title policy to be issued by the Title
Insurer or additional title premiums payable by Seller, if any, in connection
with the omission of such Title Exceptions), shall be paid by Purchaser. The
cost of obtaining new or updated surveys for the Unit shall be paid by
Purchaser.

         (d) If any title report discloses judgments, bankruptcies or other
returns against other Persons having names the same as, or similar to, that of
Seller, Seller on request, shall deliver to the Title Insurer affidavits showing
that such judgments, bankruptcies or other returns are not against Seller in
order to induce the Title Insurer to omit exceptions with respect to such
judgments, bankruptcies or other returns or to insure over same. In addition,
Seller, on request, shall deliver to the Title Insurer, all customary affidavits
reasonably required by the Title Insurer to omit (i) exceptions with respect to
municipal emergency repairs, (ii) exceptions with respect to (y) retroactive
street vault charges, together with interest and penalties thereon, and (z) work
done by The City of New York upon the Unit or the Common Elements or any demand
made by The City of New York for any such work that may result in charges by The
New York City Department of Environmental Protection for water tap closings or
any related work, (iii) exceptions with respect to fees for inspections,
reinspections, examinations and services performed by the Department of
Buildings or for permits issued by the Department of Buildings to Seller and
(iv) any other exceptions of a similar type of which Seller has actual knowledge
and which relate to the Unit. Seller, on request, shall also deliver to the
Title Insurer all customary affidavits reasonably required by the Title Insurer
to modify or omit (in accordance with the customary practice in New York City)
those standard printed exceptions to title contained in the form of 1992 ALTA
owner's title insurance policy employed by the Title Insurer, so customarily
modified or omitted.

         5.  BROKERS AND ADVISORS.

         (a) Purchaser represents and warrants that it has not dealt or
negotiated with any broker with respect to the transactions contemplated by this
Agreement other than Jones Lang LaSalle and LaSalle Investment Management, Inc.
(collectively, "JLL") and Cooper-Horowitz, Inc. ("PURCHASER'S MORTGAGE BROKER")
and Purchaser shall pay, or shall cause third parties other than Seller or its
affiliates to pay, all fees due to Purchaser's Mortgage Broker in connection
therewith, if any, pursuant to a separate agreement. Purchaser shall indemnify,
defend and hold Seller harmless from and against any claims by Purchaser's
Mortgage Broker for any brokerage commission or other fee due to Purchaser's
Mortgage Broker in connection with the transactions contemplated by this
Agreement. Purchaser shall also indemnify, defend and hold Seller harmless, from
and against any and all loss, cost, damage, claim, liability and expense
(including reasonable attorneys' fees) resulting from a breach of the foregoing
representation and warranty.

                                       14


         (b) Seller represents and warrants that it has not dealt or negotiated
with any broker with respect to the transactions contemplated by this Agreement
other than JLL and Purchaser's Mortgage Broker and Seller shall pay all fees due
to JLL in connection therewith pursuant to a separate agreement. Seller shall
indemnify, defend and hold Purchaser harmless, from and against any and all
loss, cost, damage, claim, liability and expense (including, without limitation,
reasonable attorneys' fees) resulting from a breach of the foregoing
representation, warranty and covenant.

         (c) Purchaser shall be responsible for the payment of all professionals
and advisors retained by Purchaser in connection with the transactions
contemplated by this Agreement. Seller shall be responsible for the payment of
all professionals and advisors retained by Seller in connection with the
transactions contemplated by this Agreement.

         (d) The provisions of this SECTION 5 shall survive the Closing for a
period without expiration.

         6.  CUSTOMARY CLOSING ADJUSTMENTS.

         (a) The following are to be apportioned for the Unit as of the
Apportionment Date (subject to the rights of tenants under their respective
Leases and the rights of the Board of Managers generally), and shall (except as
expressly set forth herein) constitute an adjustment with respect to the
Purchase Price as of the Apportionment Date:

                  (i)     real estate taxes, personal property taxes and all
         assessments (special and general) for the current tax fiscal period in
         progress on the Apportionment Date (it being agreed that the same shall
         be adjusted on an accrual basis). If the rate or amount of such taxes
         shall not be fixed prior to the Closing Date, the adjustment thereof as
         of the Apportionment Date shall be upon the basis of the rate for the
         preceding tax fiscal period applied to the latest assessed valuation
         (or, if none, other basis of valuation, including written opinions of
         tax adjusters or as otherwise agreed to by Seller and Purchaser), and
         the same shall be further adjusted no later than thirty (30) days after
         the date on which the taxes for the current tax fiscal period in
         progress on the Apportionment Date are paid;

                  (ii)    unless final meter readings are obtained on the
         Apportionment Date (for which Seller shall be solely responsible),
         vault charges, water and sewer service charges, and charges for all
         other public utilities, including steam, electricity and gas (to the
         extent the Unit owner is responsible for the payment thereof). The
         rights to the return of any deposits with utility companies shall be
         retained by Seller. Purchaser shall promptly, upon request of Seller,
         put up any replacement deposit on or about the Closing Date that may be
         required by a utility company as a precondition to the release of
         Seller's deposit;

                  (iii)   base rents, fixed rents, additional rents, escalation
         rents, percentage rents and any other rents (exclusive of advance rents
         and security deposits) paid or payable for the billing period in
         progress as of the Apportionment Date in accordance with SECTION 8A; it
         being agreed that to the extent, on the

                                       15


         Apportionment Date, additional rents, escalation rents, percentage
         rents or other rents have not been collected for such billing period,
         then each such item shall be adjusted retroactively to the
         Apportionment Date in accordance with SECTION 8A and this SECTION 6 no
         later than thirty (30) days after each such item has been collected.
         Percentage rent, payments or reimbursements on account of operating
         expenses and real estate taxes, utility charges and any other payments,
         reimbursements or contributions by tenants under the Leases shall be
         prorated as follows: (y) with respect to percentage rents (if any),
         Purchaser shall furnish to Seller promptly upon receipt copies of all
         sales reports from tenants who owe percentage rent for any period prior
         to the Apportionment Date, whereupon the percentage rent due (if any)
         shall be promptly calculated and the proration between Seller and
         Purchaser computed as of the Apportionment Date; and (z) the amount of
         any other rents, payments, reimbursements or contributions to be made
         by any tenant shall be computed in accordance with such tenant's Lease
         as existing as of the Apportionment Date; and (PROVIDED THAT such
         tenant's rent payments are not in arrears) Purchaser shall remit to
         Seller Seller's pro rata portion of such percentage rents (if any) and
         any other rents, payments, reimbursements or contributions (based upon
         apportionment being made as of the Apportionment Date) promptly after
         such rents, payments, reimbursements or contributions have been
         collected by Purchaser from such tenant. If Seller has collected
         estimated amounts of prepayments in excess of the amounts properly
         payable under any tenant's Lease, (1) Seller shall promptly remit such
         excess to Purchaser after notice from Purchaser and after such excess
         is verified by a review or analysis of estimated prepayments in
         accordance with such tenant's Lease, (2) Purchaser shall promptly remit
         to the applicable tenant any such excess paid over to Purchaser
         pursuant to the preceding clause (1), and (3) Purchaser shall indemnify
         and hold Seller harmless from all claims, demands, causes of actions,
         losses, damages, liabilities, costs and expenses (including reasonable
         attorneys' fees and disbursements) asserted against or incurred by
         Seller in connection with or arising out of Purchaser's failure to
         fulfill its obligations pursuant to the preceding CLAUSE (2);

                  (iv)    permit fees and license fees with respect to any
         assigned permits and licenses;

                  (v)     charges and payments under assignable Contracts (other
         than those terminated in accordance with SECTION 11(a)(x)) or permitted
         renewals or replacements thereof; and

                  (vi)    insurance premiums and other similar prepaid expenses
         (to the extent Purchaser is able to retain the same and elects to do
         so), Common Charges and Limited Common Charges (as such terms are
         defined in the Condominium Declaration) and any Grand Central
         Partnership payments or dues applicable to the Unit, operating
         agreement payments (if such agreements are assumed by Purchaser) and
         such other items that, in New York, New York, are customarily prorated,
         adjusted or paid in accordance with the "customs in respect to title
         closings" recommended by The Real Estate Board of New York, Inc., as
         amended

                                       16


         and in effect on the date of Closing, in connection with the sale or
         exchange of property similar to the Unit, consistent with the terms and
         provisions of this Agreement.

         (b) All funds in any operating accounts, reserve accounts or any other
accounts pertaining to the Unit on the Apportionment Date, whether in the name
of Seller or any property manager of the Unit, shall (subject to the terms of
any applicable Leases and the adjustments required under this Agreement) be
retained by Seller or applied as Seller shall direct, and all cash, coins and
petty cash to which Seller is entitled (including cash in coin operated
machines, if any) located in the Unit shall be counted by Seller or any such
property manager on the Apportionment Date and the same shall be retained by
Seller or remitted to Seller by any such property manager.

         (c) The security deposits and advance rents with respect to the Leases
(together with any interest thereon required pursuant to the terms of the Leases
or applicable law) shall not be pro-rated, but instead shall be paid over to
Purchaser on the Closing Date, PROVIDED THAT, if such security deposits or
advance rents are in the possession or control of any property manager, at
Purchaser's request, Seller shall direct such property manager in writing to
retain possession or control thereof for the benefit of Purchaser. Promptly
after the Closing (irrespective of when such Closing occurs), Seller shall
transfer or cause to be transferred to Purchaser any and all letters of credit
and Seller's interest in any certificates of deposit held by Seller as security
for a tenant's performance under any of the Leases being assigned to Purchaser.
If any such letter of credit is non-transferable, Seller shall use its good
faith efforts to have such letter of credit reissued in the name of Purchaser
(at Seller's sole cost and expense), and failing that, Seller agrees to continue
holding any such non-transferable letter of credit and agrees to present the
letter of credit for payment or to release the letter of credit on the written
instructions of Purchaser and will remit any funds collected thereunder to
Purchaser (less any reasonable costs of collection), PROVIDED THAT Seller is
indemnified and held harmless by Purchaser from and against any liability, cost
or expense as a result thereof.

         (d) Purchaser shall be entitled to a credit at Closing in the amount of
$170,400.00 in respect of costs that Purchaser will incur as a result of it
having assumed Seller's obligations under the Systems Agreement pursuant to the
Master Assignment and Assumption Agreement.

         (e) Seller shall be responsible for the payment of all Unanticipated
Capital Expenditures incurred and actually required to be paid for Unanticipated
Capital Expenditures incurred during the Interim Period. If on the Closing Date
any Unanticipated Capital Improvements have not been completed and/or funded by
Seller, then Purchaser shall receive a credit at Closing in an amount equal to
the cost to complete any such unfunded work as reasonably estimated by Seller.

         (f) Seller and Purchaser shall each be responsible for the payment of
those (i) Leasing Commissions relating to Existing Leases and Approved New
Leases allocable to each such party as set forth on SCHEDULE 6(f)(i), (ii)
Tenant Allowances that are the obligation of the landlord under the Existing
Leases and the Approved New Leases allocable to each such party as set forth on
SCHEDULE 6(f)(ii), and (iii) Seller shall be responsible for the Budgeted
Repairs allocated to Seller set forth on SCHEDULE 6(f)(iii), as such payments
come due, and Purchaser

                                       17


shall from and after the Closing Date be responsible for all other repairs,
whether Budgeted Repairs or otherwise. If any amount of Budgeted Repairs
required to be paid by Seller pursuant to SCHEDULE 6(f)(iii) has not been paid
on or before the Closing Date, Purchaser shall be entitled to a credit at
Closing in such amount. Seller shall not delay any planned payment or planned
work in respect of Budgeted Repairs for the sole purpose of allocating the
responsibility for such payment to Purchaser.

         (g) Intentionally Omitted.

         (h) Seller and Purchaser agree to use reasonable efforts to calculate
all adjustments required under this SECTION 6 that are ascertainable on the
Apportionment Date by the Apportionment Date but not later than the sixty (60)
days after the Apportionment Date. Each other item of income and expense that is
subject to adjustment under this SECTION 6 but that is not ascertainable on the
Apportionment Date will be adjusted retroactive to the Apportionment Date, and
the payment made on such adjustment within sixty (60) days after the date that
such adjustment becomes ascertainable (I.E., the date by which each party, in
its good faith business judgment, has sufficient information to make such
adjustment). The parties agree that each party shall have the right, during the
period commencing on the Closing Date and terminating at the close of business
on the one hundred eightieth (180th) day after the Closing Date, on reasonable
advance written notice to the other, from time to time during regular business
hours, to review the books and records of such other party pertaining solely to
the operations of the Unit to the extent necessary to confirm the amounts of
adjustments payable to Seller and/or Purchaser following the Apportionment Date
and in furtherance thereof the parties shall, upon reasonable advance written
notice, make their respective books and records available for the other during
regular business hours and shall use their good faith commercially reasonable
efforts to cause the managing agent of the Common Elements to make available the
applicable portion of its books and records for such purpose. Seller and
Purchaser shall cooperate as necessary following the Closing Date in order to
promptly and in good faith discharge their respective obligations under this
SECTION 6. Notwithstanding the foregoing, any claim for an adjustment under
SECTION 6(a) will be valid if made in writing with reasonable specificity within
one (1) year after the Closing Date, except in the case of items of adjustment
which at the expiration of such period are subject to pending litigation or
administrative proceedings. Claims with respect to items of adjustment that are
subject to litigation or administrative proceedings will be valid if made on or
before the later to occur of (i) the date that is one (1) year after the Closing
Date and (ii) the date that is one hundred eighty (180) days after a final
non-appealable order shall have issued in such litigation or administrative
hearing. Both parties shall use good faith efforts to resolve any disputed
claims promptly. The provisions of this SECTION 6 shall survive the Closing.
Purchaser shall notify, or shall cause any property manager retained by it to
notify, Seller of any reimbursement adjustment to which Seller becomes entitled
under the provisions of this SECTION 6 promptly after Purchaser or such property
manager determines that such reimbursement adjustment is due to Seller.

         7.  EFFECT OF CERTAIN LEASE EVENTS.

         (a) In addition to the Customary Adjustment being calculated as of the
Apportionment Date with respect to the Unit in accordance with the provisions of
SECTION 6 and

                                       18


the adjustments set forth in SECTION 8A, the adjustments set forth in this
SECTION 7 shall, to the extent applicable, be made on the Closing Date.

         (b) If a Contractual Right Lease Event occurs with respect to an
Existing Lease during the Interim Period, then (i) during the Interim Period,
Seller alone shall continue to be responsible for the payment of all costs and
expenses attributable to such Existing Lease required to be paid during the
Interim Period (as adjusted for the effect of the Contractual Right Lease Event)
and Seller alone shall continue to be entitled to the receipt of all income
generated from such Existing Lease (as adjusted for the effect of the
Contractual Right Lease Event) and (ii) from and after the Closing Date,
Purchaser alone shall be responsible for the payment of all costs and expenses
attributable to such Existing Lease (as adjusted for the effect of the
Contractual Right Lease Event) and Purchaser alone shall be entitled to the
receipt of all income generated from such Existing Lease (as adjusted for the
effect of the Contractual Right Lease Event). Without limiting the generality of
the foregoing, if upon the occurrence of a Contractual Right Lease Event that
results in the termination of any Existing Lease, any fee or other payment
required to be made by the applicable tenant under such Existing Lease is in
fact paid during the Interim Period as a condition to the termination of such
Existing Lease, such fee or other payment shall belong exclusively to Seller.
Any subsequent re-leasing of the space (or any portion thereof) previously
demised under such terminated Existing Lease during the Interim Period shall
constitute a Purchaser Consent Action, subject to the provisions of Section
8(a)(i), it being the intention of the parties that Purchaser shall ultimately
bear all the risks and rewards of such re-leasing; PROVIDED, HOWEVER, (y) during
the Interim Period, subject to the following provisions of this Section, Seller
alone shall be responsible for the payment of all costs and expenses of
re-leasing the space in question that are required to be paid during the Interim
Period (including all tenant improvement expenses, tenant allowances, leasing
commissions, referral fees and legal fees) and Seller alone shall be entitled to
the receipt of all income therefrom and (z) from and after the Closing Date,
Purchaser alone shall be responsible for the payment of all costs and expenses
of re-leasing the space in question (including all tenant improvement expenses,
tenant allowances, leasing commissions, referral fees and legal fees) and
Purchaser alone shall be entitled to the receipt of all income therefrom.
Notwithstanding the foregoing, (1) if the expenses incurred by Seller during the
Interim Period in connection with such re-leasing of the space (or any portion
thereof) previously demised under an Existing Lease exceeds the gross income
received by Seller during the Interim Period as the result of such re-leasing,
then Seller shall receive a credit at Closing in the amount of such excess and
(2) if the gross income received by Seller during the Interim Period as the
result of such re-leasing of the space (or any portion thereof) previously
demised under an Existing Lease exceeds the expenses incurred by Seller during
the Interim Period in connection with such re-leasing, then Purchaser shall
receive a credit at Closing in the amount of such excess. Notwithstanding the
foregoing, with respect to any Contractual Right Lease Event that does not
result in the termination of an Existing Lease, at Closing, Seller shall also
receive a credit in an amount equal to all tenant improvement expenses, tenant
allowances, leasing commissions, referral fees and legal fees incurred in
connection with such Contractual Right Lease Event.

         (c) If an Involuntary Lease Event occurs with respect to an Existing
Lease during the Interim Period, then (i) during the Interim Period, Seller
alone shall continue to be responsible for the payment of all costs and expenses
attributable to such Existing Lease required to be paid during such Interim
Period (as adjusted for the effect of the Involuntary Lease Event) and Seller
alone shall be entitled to the receipt of all income generated from such
Existing Lease (as adjusted for the effect of the Involuntary Lease Event)

                                       19


and (ii) from and after the Closing Date Purchaser alone shall continue to be
responsible for the payment of all costs and expenses attributable to such
Existing Lease (as adjusted for the effect of the Involuntary Lease Event) and
Purchaser alone shall thereafter be entitled to all income generated therefrom.
Following the occurrence of an Involuntary Lease Event during the Interim Period
that results in a tenant vacating the space demised under an Existing Lease
prior to the scheduled expiration thereof, any subsequent re-leasing of the
space (or any portion thereof) previously demised under such Existing Lease
during the Interim Period shall constitute a Purchaser Consent Action, subject
to the provisions of SECTION 8(a)(i), it being the intention of the parties that
Purchaser shall ultimately bear all the risks and rewards of such re-leasing;
PROVIDED, HOWEVER, (y) during the Interim Period, subject to the following
provisions of this Section, Seller alone shall be responsible for the payment of
all costs and expenses of re-leasing the space in question that are required to
be paid during such Interim Period (including all tenant improvement expenses,
tenant allowances, leasing commissions, referral fees and legal fees) and Seller
alone shall be entitled to the receipt of all income therefrom and (z) from and
after the Closing Date, Purchaser alone shall be responsible for the payment of
all costs and expenses of re-leasing the space in question (including all tenant
improvement expenses, tenant allowances, leasing commissions, referral fees and
legal fees) and Purchaser alone shall be entitled to the receipt of all income
therefrom. Notwithstanding the foregoing, (1) if the expenses incurred by Seller
during the Interim Period in connection with such re-leasing of the space (or
any portion thereof) previously demised under an Existing Lease exceeds the
gross income received by Seller during the Interim Period as the result of such
re-leasing, then Seller shall receive a credit at Closing in the amount of such
excess and (2) if the gross income received by Seller during the Interim Period
as the result of such re-leasing of the space (or any portion thereof)
previously demised under an Existing Lease exceeds the expenses incurred by
Seller during the Interim Period in connection with such re-leasing, then
Purchaser shall receive a credit at Closing in the amount of such excess. The
collection of Receivables and other amounts due from tenants as the result of an
Involuntary Lease Event shall be undertaken in accordance with the provisions of
SECTION 8A and any sums actually collected as a result thereof shall be applied
in the manner prescribed in such Section.

         (d) If a Voluntary Lease Event occurs with respect to an Existing Lease
during the Interim Period, then, subject to the following provisions of this
Section, (i) during the Interim Period, Seller alone shall continue to be
responsible for the payment of those costs and expenses that are required to be
paid during such Interim Period (including all tenant improvement expenses,
tenant allowances, leasing commissions, referral fees and legal fees)
attributable to such Existing Lease (as adjusted for the effect of the Voluntary
Lease Event), and Seller alone shall continue to be entitled to the receipt of
all income generated from such Existing Lease (as adjusted for the effect of the
Voluntary Lease Event), and (ii) from and after the Closing Date, Purchaser
alone shall be responsible for the payment of all costs and expenses (including
all tenant improvement expenses, tenant allowances, leasing commissions,
referral fees and legal fees) attributable to such Existing Lease (as adjusted
for the effect of the Voluntary Lease Event) and Purchaser alone shall be
entitled to the receipt of all income from such Existing Lease (as adjusted for
the effect of the Voluntary Lease Event). At Closing, Seller shall receive a
credit in an amount equal to all tenant improvement expenses, tenant allowances,
leasing commissions, referral fees and legal fees incurred during the Interim
Period as the result

                                       20


of any Voluntary Lease Event with respect to an Existing Lease, including all
such tenant improvement expenses, tenant allowances, leasing commissions,
referral fees and legal fees incurred in connection with the re-leasing of any
space that is vacated as a result of such Voluntary Lease Event.

         (e) The provisions of this SECTION 7 shall survive the Closing for a
period of two (2) years.

         8.  OPERATION OF THE UNIT PRIOR TO CLOSING.

         During the Interim Period, Seller shall have the right and the
obligation to continue to operate and maintain the Unit, subject to the
limitations set forth in the Condominium Declaration. In connection therewith:

                  (a)    From the date hereof until the Closing, Seller shall
         not take, or allow any property manager retained by it to take, any
         Purchaser Consent Action, without the prior written consent of the
         Purchaser (which consent may be withheld in Purchaser's sole and
         absolute discretion). With respect to any proposed Purchaser Consent
         Action to be submitted to Purchaser for its consent pursuant to the
         preceding sentence, Purchaser shall consent or deny its consent, within
         five (5) business days following receipt by Purchaser of Seller's
         notice requesting Purchaser's consent to the proposed action and
         providing Purchaser with all background information necessary for
         Purchaser to make its decision. Failure to respond within such five (5)
         business day period shall be deemed to be an approval of the Purchaser
         Consent Action in question. It is understood that a non-discretionary
         lease renewal, expansion, surrender of space, sublease or assignment
         right or other similar right expressly set forth in an Existing Lease
         in favor of a tenant shall not be deemed to be a Purchaser Consent
         Action to the extent that the specific terms therefor are embodied in
         the lease in question and are non-subjective in nature. For example, if
         a renewal has been granted in favor of a tenant for a specific term and
         at a specified fixed dollar rent per square foot, such renewal will not
         be a Purchaser Consent Action. On the other hand, if a renewal has been
         granted to a tenant for a specific term and at a fair market rent to be
         mutually agreed upon by the Seller and tenant, the ability of Seller to
         agree upon a fair market rent shall be a Purchaser Consent Action. In
         addition to the foregoing, Seller shall not take, or allow any property
         manager retained by it to take, any actions contained in clause (i) of
         the definition of Excluded Decisions to the extent such action relates
         to the granting or withholding of a consent right with respect to a
         material matter under any Lease or involves the incurrence of a
         material expenditure, obligation or other liability without first
         providing written notice to Purchaser of its intention to do so, and
         the reasons therefor; PROVIDED, HOWEVER, Seller agrees that, to the
         extent requested in writing by Purchaser within three (3) business days
         after receipt by Purchaser of such notice from Seller, Seller shall
         refrain from taking any such contemplated action, PROVIDED THAT
         Purchaser agrees to indemnify and hold Seller harmless from any loss,
         cost, damage, claim, liability and expense (including reasonable
         attorneys' fees) which Seller shall incur resulting from Seller's
         failure to take any such action.

                                       21


                  (b)    Intentionally Omitted.

                  (c)    From the date hereof until the Closing, Seller shall
         not take, or omit to take, any action that would have the effect of
         violating in any material respect any of the representations,
         warranties, covenants and agreements of Seller contained in this
         Agreement. Nothing contained in the foregoing sentence shall be
         construed to preclude Seller from taking, or omitting to take, any
         action that is (x) approved in writing by Purchaser (whether as a
         Purchaser Consent Action or otherwise), (y) required or permitted to be
         taken pursuant to this Agreement, or (z) pertaining to the Common
         Elements and approved by the Board of Managers. From the date hereof
         until the Closing, Purchaser shall not take, or omit to take, any
         action that would have the effect of violating in any material respect
         any of the representations, warranties, covenants and agreements of
         Purchaser contained in this Agreement.

                  (d)    From the date hereof until the Closing, Seller shall
         not sell, assign, or convey any right, title or interest whatsoever in
         or to the Unit, or create or to Seller's Knowledge permit to exist any
         lien, security interest, easement, encumbrance, charge or condition
         affecting the Unit (other than a Permitted Encumbrance), without the
         prior consent of Purchaser except to the extent relating to (x) leasing
         of the Unit or portions thereof as permitted in accordance with this
         Agreement, (y) items affecting the Common Elements approved by the
         Board of Managers, or (z) items approved in writing by Purchaser
         (whether as a Purchaser Consent Action or otherwise).

                  (e)    From the date hereof until the Closing, Seller shall
         promptly deliver to Purchaser copies of (x) written default notices,
         notices of lawsuits and notices of violations affecting the Unit that
         are sent or actually received by Seller, (y) without duplication of
         anything contained in the preceding CLAUSE (x), any notice received
         from The City of New York, any taxing authority and any other
         municipal, governmental or quasi-governmental entity or agency
         pertaining to the Unit, and any notices received from the Grand Central
         Partnership, and (z) monthly operating statements for the Unit after
         the same have been created.

                  (f)    From the date hereof until the Closing, Seller shall
         maintain in full force and effect business interruption insurance to
         cover loss of rental income in an amount not less than twelve (12)
         months' projected gross income of the Unit and the other insurance
         polices described in SCHEDULE 11(a)(xv), and shall otherwise continue
         to operate the Unit in substantially the same manner as it operated the
         Unit prior to the execution and delivery of this Agreement, and shall
         pay all operating expenses and real estate taxes that are the
         responsibility of the owner of the Unit during the Interim Period.

                  (g) From the date hereof until the Closing, Seller shall
         deliver to Purchaser, promptly after the execution and delivery thereof
         by all parties thereto, copies of all agreements pertaining to Lease
         Events.

                                       22


                  (h) From the date hereof until the Closing, Seller and
         Purchaser shall convene (by phone or in person) not less frequently
         than once per calendar week to discuss any and all matters relating to
         the operation, management, leasing, maintenance or repair of the Unit.

                  (i) From the date hereof until the Closing, Seller will use
         reasonable efforts to enforce its rights as landlord under the Lease
         with Merrill, Lynch, Pierce, Fenner & Smith Incorporated to cause such
         tenant to perform such work, obtain such permits or consents or to
         otherwise act in a fashion to obtain its public assembly permit and to
         facilitate the issuance of a permanent certificate of occupancy for the
         Building.

         8A. TREATMENT OF CERTAIN MATTERS.

         (a) COLLECTION OF RECEIVABLES, CURRENT SUMS AND ARREARAGES.

         (1) Seller shall, until the Closing Date, undertake its customary
collection efforts to collect all Receivables and other amounts due from tenants
(subject to the limitations provided in SECTION 8A(a)(5)), which may include the
submission of monthly invoices and follow-up invoices, and may (but need not)
include the commencement or continuation of litigation or other proceedings, it
being agreed that any monies received by Seller as a result of such collection
efforts (net of the reasonable costs allocable to the collection of the same)
attributable to the period prior to the Closing Date shall (except as
specifically provided to the contrary in SECTIONS 7(b), (c) and (d)) belong to
Seller and shall not constitute a credit against the Purchase Price.

         (2) Purchaser shall, from and after the Closing Date, undertake its
customary collection efforts on behalf of Seller to collect all Receivables for
a period of six (6) months after the Closing Date (subject to the limitations
provided in SECTION 8A(a)(5)), which may include the submission of monthly
invoices and follow-up invoices, and may (but need not) include the commencement
or continuation of litigation or other proceedings, it being agreed that in such
cases any monies received by Purchaser from and after the Closing Date from any
party liable for any portion of the Receivables to be collected by Purchaser
shall be applied in the following order:

         FIRST            to the payment pro-rata (on the basis of costs
                          incurred) of all reasonable costs of collection,
                          including reimbursement to Seller or Purchaser of any
                          legal fees or collection costs reasonably incurred by
                          either of them and allocable to the collection of such
                          Receivables pursuant to the foregoing provisions of
                          this Section,

         SECOND           to the payment of monies owed to Seller and Purchaser
                          for the billing period in progress on the Closing
                          Date,

         THIRD            to Purchaser for sums owed to Purchaser relating to
                          billing periods after the billing period in progress
                          as of the Closing Date, and

                                       23


         LAST             to the balance of any Receivables.

         (3) If within six (6) months following the Closing Date, any of the
Receivables to be collected by Purchaser that are payable to Seller in
accordance with the terms of this SECTION 8A(a) have not been collected and
remitted to Seller, or Purchaser has not commenced litigation to collect such
Receivables, then Seller may undertake its own efforts to collect such
Receivables, including the commencement of litigation and other proceedings (but
Seller shall not seek to evict any tenant or terminate any Lease), and in which
event all sums collected by Seller as a result of such litigation (after payment
of all costs and expenses) shall be applied in full satisfaction of the subject
Receivables, it being agreed that Seller shall refrain from taking any such
efforts during the six (6) month period following the Closing Date.

         (4) With respect to any pending litigation or other proceedings to
collect any Receivables from tenants in occupancy on the Closing Date, Purchaser
shall have the option on the Closing Date of either (i) continuing such
litigation or proceedings (the costs of which shall be equitably apportioned
between Seller and Purchaser, based upon the amounts ultimately paid to each,
and reimbursed out of the first monies collected, if any) and Purchaser shall be
substituted as the plaintiff, if necessary, or (ii) not continuing the
litigation, whereupon Seller may continue such litigation in its own name and at
its sole cost and expense, PROVIDED THAT such litigation shall not result in the
eviction of the tenant or the termination of its Lease without Purchaser's
consent, and in which event all sums collected by Seller as a result of such
litigation (after payment of all actual out-of-pocket costs and expenses) shall
be applied in full satisfaction of the subject Receivables.

         (5) Notwithstanding anything hereinabove provided, (i) during the
Interim Period, Seller shall not settle or compromise any claims against any
tenants of the Unit without Purchaser's prior written approval, it being agreed
that the settlement or compromise of any such claims shall constitute a
Purchaser Consent Action, subject to the provisions of SECTION 8(a) of this
Agreement, (ii) after the Closing, neither Seller nor Purchaser shall settle or
compromise any claims against any tenants of the Unit that include both
Receivables payable to Seller and amounts payable to Purchaser without the other
party's prior written approval, which approval shall not be unreasonably
withheld or delayed, and (iii) to the extent the Receivables that are subject to
collection are the Receivables identified in clause (ii) of the definition of
Receivables, the rights and obligations of Seller and Purchaser shall be
qualified to provide that such parties shall use commercially reasonable good
faith efforts to cause the Board of Managers to comply with the relevant
provisions of SECTION 8A. Notwithstanding the foregoing, Purchaser shall have
the right to settle or compromise a claim against a tenant of the Unit without
the consent of (but after prior notice to) Seller to the extent such claim
relates solely to the period of time after the Closing and provided that the
settlement or compromise of such claim does not have a material adverse effect
on any claim that Seller may have against such tenant.

         (6) Notwithstanding anything to the contrary hereinabove provided,
Seller shall retain the sole right to collect (in such manner as it shall deem
appropriate) those Receivables, if any, listed on SCHEDULE 8A(a)(6) as well as
Receivables with respect to any tenant whose lease has terminated prior to the
Apportionment Date and has vacated its demised premises, it being further agreed
that Purchaser shall not be required to undertake any collection efforts with
respect to such Receivables.

                                       24


         (7) Any monies received by Seller or Purchaser that are to be applied
to sums owed to the other party hereto hereunder (whether on account of
Receivables, current sums due, arrearages or otherwise) shall be held in trust
by Seller or Purchaser, as the case may be, for the benefit of the other party
and remitted to such other party promptly after receipt. Seller and Purchaser
shall reasonably cooperate with each other in the collection of Receivables and,
provided there is no liability or material expense associated therewith, shall
execute any documents reasonably requested by the other to collect such
Receivables.

         (b) PROTEST PROCEEDINGS.

                  (1)     GENERALLY. As of the date of this Agreement, Seller
         has engaged various law firms or consultants to protest the valuation
         of the Unit ("PROTEST PROCEEDINGS") for the purpose of protesting the
         amount of ad valorem taxes for certain tax fiscal periods, some of
         which taxes may have been paid by Seller and some of which taxes either
         are not yet due and payable or have not been paid. With respect to the
         tax year in which the Closing occurs, and all prior tax years, Seller
         is hereby authorized to continue any Protest Proceeding for the Unit,
         it being acknowledged that the trial or settlement of any such Protest
         Proceeding during the Interim Period shall constitute a Purchaser
         Consent Action, subject to the provisions of SECTION 8(a) (other than
         settlements that have been accepted by Seller but are pending
         governmental approval as described in SCHEDULE 11(a)(ix), as to which
         no Purchaser Consent is required). All Net Refunds and credits
         attributable to any tax year prior to the tax year in which the Closing
         occurs shall belong to and be the property of Seller, subject to the
         rights of tenants under their respective Leases. All Net Refunds and
         credits attributable to any tax year subsequent to the tax year in
         which the Closing occurs shall belong to and be the property of
         Purchaser, subject to the rights of tenants under their respective
         Leases. All Net Refunds and credits attributable to any tax year not
         described in the preceding two (2) sentences shall be divided between
         Seller and Purchaser in accordance with the apportionment of taxes set
         forth in SECTION 8A(b)(2). Seller and Purchaser shall cooperate with
         one another in connection with the prosecution of any such proceedings
         and to take all reasonable steps, whether before or after the Closing
         Date, as may be reasonably necessary to carry out the intention of the
         foregoing, including to the extent in a party's possession, the
         delivery to the party pursuing the appeal of any relevant books and
         records, including receipted tax bills and canceled checks used in
         payment of such taxes, and, provided that there is no liability or
         material expense to the party delivering such materials in doing so,
         the execution of any and all consents or other documents, and the
         undertaking of any act necessary for the collection of such refund. The
         parties agree to keep one another apprised of all such proceedings, to
         provide one another (except to the extent that the attorney-client
         privilege or work product immunity may be adversely affected) with
         copies of all relevant books, records and documentation relating to any
         such proceeding, and with respect to any course of action which the
         pursuing party could reasonably expect to have a material impact on any
         proceeding or on the outcome of any proceeding, such party agrees to
         consult with the other party and to obtain such party's consent (which
         consent shall not be unreasonably withheld or delayed) before
         proceeding with any such action.

                                       25


         Notwithstanding the foregoing limitation, Seller agrees that neither
         Seller nor its representatives will withhold, because of the
         attorney-client privilege or work product immunity, from Purchaser or
         its representatives any relevant information received by Seller or its
         representatives from, or delivered by Seller or its representatives to,
         the New York City taxing authorities. If either party hereto shall
         receive any refund payments contemplated by this SECTION 8A(b) that are
         properly payable to the other party, such payments shall be held in
         trust by such party, for the benefit of the other, and remitted to such
         other party promptly after receipt.

                  (2)     The Net Refund payable by virtue of a favorable
         determination resulting from any Protest Proceeding with respect to the
         tax fiscal period in progress on the Apportionment Date shall be
         prorated between Seller and Purchaser on a per diem basis, with Seller
         being entitled to receive the portion thereof allocated to the portion
         of such tax fiscal period up to and including the Apportionment Date.

         The term "NET REFUND" as used herein shall mean the portion of any
         refund (including any interest payable thereon) that is payable by
         virtue of a favorable determination resulting from any Protest
         Proceeding and that is entitled to be retained by the party so entitled
         thereto pursuant to the foregoing provisions after (i) payment or
         reimbursement (on a pro-rata basis) of all fees and out-of-pocket
         expenses including counsel fees and disbursements and consultant's fees
         incurred in obtaining such refund, the allocation of such expenses to
         be based upon the total refund obtained in such proceeding and in any
         other proceeding simultaneously involved in the trial or settlement and
         (ii) the refunding by such party of the portion of any such refund, if
         any, owing to tenants under the Leases (whether or not the same then
         are in effect) on account of such refund attributable to the applicable
         periods covered thereby.

                  (3)     Intentionally Omitted.

                  (4)     CONTROL OF PROTEST PROCEEDINGS, SETTLEMENT AND
         COMPROMISE. In connection with any Protest Proceeding for the tax
         fiscal period in progress on the Closing Date, at Purchaser's request
         Seller shall, if possible, cause Purchaser to be substituted for Seller
         in such Protest Proceeding and any other pending Protest Proceedings
         for tax fiscal periods commencing prior to the tax fiscal period in
         progress on the Closing Date (except those as to which settlement is
         now pending), or if not possible, Seller shall permit Purchaser to
         control the conduct of all such Protest Proceedings. Notwithstanding
         anything hereinabove provided, (i) during the Interim Period, Seller
         shall not settle or compromise any Protest Proceedings in which taxes
         for any tax fiscal period in progress on or prior to the Closing are
         being adjudicated (other than those as to which settlement is now
         pending) without Purchaser's prior written approval, it being agreed
         that the settlement or compromise of any Protest Proceedings (except
         those as to which settlement is now pending) shall constitute a
         Purchaser Consent Action, subject to the provisions of SECTION 8(a) and
         (ii) after the Closing, neither Seller nor

                                       26


         Purchaser shall settle or compromise any Protest Proceedings pending on
         the Closing Date in which taxes for any tax fiscal period in progress
         on or prior to the Closing Date are being adjudicated (except those as
         to which settlement is now pending) without the other party's prior
         written approval, which approval shall not be unreasonably withheld or
         delayed. Seller and Purchaser shall otherwise cooperate with each other
         in all reasonable respects with respect to all Protest Proceedings.
         From and after the Closing Date, Purchaser shall have the right,
         subject to the above provisions of this SECTION 8A(b)(4) and subject to
         the terms and provisions of the Condominium Declaration, to withdraw,
         compromise, settle, try or otherwise deal with such petitions or
         applications with respect to the Unit as Purchaser in the exercise of
         its sole judgment shall deem appropriate.

         (c) SURVIVAL. The provisions of this SECTION 8A shall survive the
Closing for a period without expiration.

         9.  RECORDING CHARGES, TRANSFER AND CONVEYANCE TAXES; WITHHOLDING;
             INTERNAL REVENUE SERVICE REPORTING REQUIREMENTS.

         (a) RECORDING CHARGES; TAXES GENERALLY. Purchaser shall pay all
recording charges and fees and sales taxes, if any, imposed in connection with
the conveyance of the Unit to Purchaser. All real estate transfer and conveyance
taxes paid or payable in connection with the transactions herein contemplated
shall be paid by Seller and/or Purchaser in the manner hereinafter provided in
this SECTION 9.

         (b) TRANSFER TAXES.

                  (i)     Seller shall pay the New York State Real Estate
         Transfer Tax (the "STATE TRANSFER TAX") in accordance with Article 31
         of the Tax Law of the State of New York, and the New York City Real
         Property Transfer Tax (the "CITY TRANSFER TAX") imposed by Chapter 21,
         Title 11 of the Administrative Code of the City of New York, in
         connection with the conveyance of the Unit to Purchaser in accordance
         with the provisions of this Agreement. Seller shall defend, indemnify
         and hold harmless Purchaser from and against any loss, cost, damage,
         claim, liability and expense (including reasonable attorneys' fees)
         that may be suffered or incurred by Purchaser by reason of the failure
         of Seller to pay the State Transfer Tax and the City Transfer Tax, if
         applicable, as pertains to this transaction, as provided in this
         SECTION 9(b), it being understood that the foregoing indemnification
         shall not apply to any tax liability resulting from an actual
         disposition of the Unit by Purchaser following its acquisition thereof
         at the Closing.

                  (ii)    Intentionally Omitted.

                  (iii)   Seller and Purchaser shall each execute and/or swear
         to the returns or statements required in connection with the State
         Transfer Tax and the City Transfer Tax, and any other taxes referred to
         in this SECTION 9(b) or otherwise

                                       27


         applicable to the transactions contemplated by this Agreement, and
         shall deliver same, together with the check or checks of Seller and/or
         Purchaser, as the case may be, in payment thereof which are required of
         such party, to the Title Insurer on the Closing Date. All such tax
         payments shall be made by certified or bank check payable directly to
         the order of the appropriate governmental officer, or in such manner as
         the Title Insurer shall reasonably require and accept.

         and other similar rules, regulations and orders of any governmental
         entity or agency having jurisdiction over the Unit) or with any
         requirements with respect to any building, occupancy or other permit,
         license or approval of any such governmental entity or agency with
         respect to the Unit except as set forth in SCHEDULE 11(a)(xviii)(1). To
         Seller's Knowledge, SCHEDULE 11(a)(xviii)(2) contains a complete list

         or the Board of Managers are responsible) have been, and at the time of
         Closing will have been, obtained and are, and will then be, in full
         force and effect;

                  (xx)    no unused transferable development rights appurtenant
         to the Unit have been assigned or transferred to any other Person by
         Seller; and

                  (xxi)   Seller does not have any ownership interest in any
         building systems or equipment located in the Common Elements other than
         such interests as may have been created pursuant to the Master License
         Agreement or the Systems Agreement.

         (b) REPRESENTATIONS AND WARRANTIES BY PURCHASER. Purchaser hereby
represents, warrants and covenants to Seller as of the date hereof that:

                                       35


                  (i)     Each of Purchaser and Purchaser's Affiliate is a
         limited liability company duly organized, validly existing and in good
         standing under the laws of the State of Delaware. Neither Citibank,
         N.A. nor any of its affiliates has any ownership or equity interest in
         Purchaser or Purchaser's Affiliate (other than as may result from a
         foreclosure or assignment in lieu of foreclosure following a default
         under any mezzanine financing provided by Citibank, N.A. structured as
         a loan). Allied Partners Inc. and/or members of the Hadar family (or
         trusts for the benefit of such family members) are now and at Closing
         (or following the closing of the property for which the Unit and Unit
         Two are being exchanged) will be affiliates of, and/or members of,
         entities that have a direct or indirect interest in Purchaser and
         Purchaser's Affiliate;

                  (ii)    Purchaser has the legal right, power and authority to
         enter into this Agreement and perform all of its obligations hereunder,
         and the execution and delivery of this Agreement and the performance by
         Purchaser of its obligations hereunder, (x) has been duly authorized,
         and (y) will not conflict with, or result in a breach of, any of the
         terms, conditions and provisions of its organizational and governance
         documents or any law, statute, rule or regulation, or order, judgment,
         writ, injunction or decree of any court or governmental
         instrumentality, or any contract, agreement or instrument to which it
         is a party or by which it is bound, or to which it or any portion of
         its property is subject, and (z) will not require the consent,
         approval, authority or order of any court or governmental agency that
         has not been previously obtained in writing or delivered to Seller;

                  (iii)   this Agreement constitutes, and when duly executed and
         delivered by Purchaser, any and all documents, instruments and
         agreements contemplated hereunder to be executed and delivered by
         Purchaser will constitute, the valid and binding obligations of
         Purchaser, enforceable in accordance with their respective terms,
         except as such enforcement may be limited by bankruptcy laws and other
         laws or equitable principles affecting the rights of contracting
         parties generally; and

                  (iv)    Purchaser is not aware, after due investigation, of
         any fact or condition (or absence of any fact or condition) that would
         make any representation or warranty made by Seller herein untrue,
         inaccurate or incomplete in any material respect.

         (c) REPRESENTATIONS NOT CONDITIONS TO CLOSING. The representations and
warranties set forth in this SECTION 11 and all other representations and
warranties contained in this Agreement shall be true and correct in all material
respects as of the Closing Date (except to the extent any such representations
and warranties expressly relate to an earlier date and with such changes as are
permitted under, or result by reason of the effect of, this Agreement); it being
agreed, however, that if any of such representations and warranties shall not be
true and correct in all material respects as of the Closing Date, same shall not
(except to the extent otherwise provided herein) be conditions precedent to
closing the transactions contemplated herein (and the parties shall continue to
be absolutely and unconditionally obligated to consummate the transactions
contemplated under this Agreement), but the non-breaching party's

                                       36


sole rights and remedies with respect to such breach shall be as set forth in
the succeeding subsection. If Purchaser determines that any representation or
warranty made by Seller is inaccurate, misleading or incomplete in any respect
or could otherwise provide the basis for a Breach Claim, Purchaser shall inform
the Seller of the same within ten (10) days of making such determination, or the
related Breach Claim shall be deemed waived.

         (d) DAMAGES FOR BREACH OF REPRESENTATIONS. In the event of a material
breach with respect to any representation or warranty made by Seller or
Purchaser under this Agreement, the non-breaching party shall be entitled to
pursue a claim with respect to such breach if and only if (i) the non-breaching
party treats such claim as a Breach Claim, files and serves upon the breaching
party a statement of claim in arbitration setting forth with particularity the
details of such claim, the damages alleged and detailed information supporting
the same prior to the expiration of the applicable Survival Period for the
representation in question, (ii) the non-breaching party diligently pursues
Expedited Arbitration in respect of such Breach Claim until resolution of such
Breach Claim, and (iii) the liability and losses arising out of such Breach
Claim, when aggregated with all other breaches, if any, of representations and
warranties by the same party under this Agreement, and in the case of Seller,
pursuant to Seller's Certificate, shall exceed $2,000,000. Notwithstanding the
foregoing, if the rent roll attached hereto as part of SCHEDULE 11(a)(xi)
overstates the rent actually due under one or more leases, Seller shall be
liable to Purchaser for the net present value (assuming a discount rate of 7.1%)
of the difference by which the rent roll overstates such rental amounts,
PROVIDED THAT in the aggregate such overstatements (after giving credit for all
understatements of the rent actually due under one or more leases) have a net
present value equal to or in excess of $200,000; PROVIDED FURTHER THAT Purchaser
gives written notice of any such overstatement, which notice must contain a
reasonably detailed description of the facts giving rise to the assertion of an
overstatement prior to the date that is the first anniversary of the Closing
Date. "SURVIVAL PERIOD" shall mean: with respect to the representations and
warranties in SECTIONS 11(a)(i), (ii), (xvi) and (xvii) and 11(b)(i), (ii),
(iii) and (iv) a period without expiration, and with respect to all other
representations and warranties, a period of one (1) year commencing on the
Closing Date. The provisions of this SECTION 11(d) shall survive the Closing.

         (e) NET WORTH. During the period commencing on the Closing Date and
ending on the day preceding the first anniversary of the Closing Date, Seller
shall maintain a net worth of not less than $30,000,000 in cash or other liquid
assets (the "INITIAL MINIMUM NET WORTH"). If prior to the expiration of the
Survival Period for any representation made by Seller herein, Purchaser asserts
a Breach Claim against Seller with respect to such representation and the
liability and losses with respect thereto, when aggregated with other Breach
Claims against Seller with respect to this Agreement and all Seller's
Certificates are alleged to exceed $2,000,000, Seller shall, if such Breach
Claim remains unsettled as of the expiration of the applicable Survival Period,
maintain a net worth comprised of cash or other liquid assets (the "MINIMUM NET
WORTH") in an amount equal to the lesser of (i) $30,000,000 or (ii) 125% of the
aggregate amount of the alleged Breach Claims then pending, but not less than
$1,000,000. Seller shall retain the Minimum Net Worth for a period (the "NET
WORTH RETENTION PERIOD") until, with respect to any such Breach Claim, the
resolution of such Breach Claim either by (y) agreement of Seller and Purchaser
or (z) the decision by the arbitrators with respect to the Breach Claim before
them, AND if Seller shall be determined by the arbitrators to be liable for the
Breach Claim in question, until the payment to Purchaser of the damages awarded
by the arbitrators

                                       37


(which shall include all reasonable attorneys' fees, costs and expenses of
Purchaser related solely to such Breach Claim). The provisions of this SECTION
11(e) shall survive the Closing for a period without expiration.

         (f) LIMITATIONS ON CLAIMS. Purchaser shall not be entitled to assert
any claim in respect of a representation set forth in this Contract or any
Seller's Certificate if Purchaser knew or should have known (had it conducted
its due diligence prudently and in a reasonable manner), on or before the date
the representation in question is made, any fact or condition that would have
made such representation untrue, inaccurate or incomplete in any material
respect. The provisions of this SUBSECTION 11(f) shall survive the Closing for a
period without expiration.

         (g) ACKNOWLEDGMENTS OF PURCHASER. Purchaser acknowledges and agrees for
the benefit of Seller that:

                  (i)     EXCEPT AS OTHERWISE EXPRESSLY STATED IN THIS AGREEMENT

         FORTH HEREIN, SELLER AND PURCHASER HEREBY AGREE THAT, EXCEPT FOR THE
         SURVIVING REPRESENTATIONS, SELLER HAS NOT MADE AND IS NOT MAKING ANY
         REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, WRITTEN OR ORAL, AS
         TO (A) THE NATURE OR CONDITION, PHYSICAL OR OTHERWISE, OF THE UNIT OR

                                       38


         CIRCUMSTANCES WHICH AFFECT OR MAY AFFECT THE UNIT OR ANY USE TO WHICH
         THE UNIT MAY BE PUT, (E) ANY CONDITIONS AT OR WHICH AFFECT OR MAY
         AFFECT THE UNIT WITH RESPECT TO ANY PARTICULAR PURPOSE, USE,
         DEVELOPMENT POTENTIAL OR OTHERWISE, (F) THE AREA, SIZE, SHAPE,

         EXTENT OF TITLE TO THE UNIT, OR ANY EASEMENT, SERVITUDE, RIGHT-OF-WAY,

         OTHERWISE THAT MAY AFFECT TITLE TO THE UNIT, (H) ANY ENVIRONMENTAL,
         GEOLOGICAL, STRUCTURAL, OR OTHER CONDITION OR HAZARD OR THE ABSENCE
         THEREOF HERETOFORE, NOW OR HEREAFTER AFFECTING IN ANY MANNER THE UNIT,
         INCLUDING BUT NOT LIMITED TO, THE PRESENCE OR ABSENCE OF ASBESTOS OR
         ANY ENVIRONMENTALLY HAZARDOUS SUBSTANCE ON, IN, UNDER OR ADJACENT TO
         THE UNIT, (I) THE COMPLIANCE OF THE UNIT OR THE OPERATION OR USE OF THE
         UNIT WITH ANY APPLICABLE RESTRICTIVE COVENANTS, OR WITH ANY LAWS,

         PROVISIONS OF THIS SECTION 11(G) SHALL BE BINDING ON PURCHASER AND
         SHALL SURVIVE THE CLOSING.

                  (ii)    PURCHASER HAS BEEN GIVEN THE OPPORTUNITY TO INSPECT
         THE UNIT, AND THE EXISTING LEASES, THE CONTRACTS AND OTHER MATERIALS
         (INCLUDING TITLE MATERIALS AND FINANCIAL REPORTS) RELATING TO THE UNIT

         RETAINED SUCH ENVIRONMENTAL CONSULTANTS, STRUCTURAL ENGINEERS AND OTHER
         EXPERTS AS IT DEEMED NECESSARY TO INSPECT THE UNIT AND REVIEW SUCH
         MATERIALS. PURCHASER IS RELYING ON ITS OWN INVESTIGATION AND THE ADVICE
         OF ITS EXPERTS REGARDING THE UNIT, AND UPON ITS REVIEW OF EXISTING

         MAY BE EXPRESSLY SET FORTH IN THE SURVIVING REPRESENTATIONS.

         12. CONDITIONS PRECEDENT TO CLOSING.

         (a) The obligation of Purchaser to consummate the transactions
hereunder shall be contingent upon (i) Seller's delivery of the documents and
instruments required to be delivered by Seller pursuant to SECTIONS 10(a) and
10(c), (ii) the simultaneous closing of the transactions described in the Unit
Two Contract Assignment and Assumption Agreement, PROVIDED THAT if Seller or
Citibank, N.A. elects to postpone the closing of the transactions described in

then Purchaser shall, within ten (10) business days of receipt of notice of such
election, have the right to terminate this Agreement and receive a return of the
Deposit and PROVIDED FURTHER THAT the failure of Purchaser's Affiliate to
perform with respect to the transactions contemplated in the Unit Two Assignment
and Assumption Agreement shall not excuse Purchaser's performance hereunder or
otherwise form the basis of any claim by Purchaser that there is a failure of a
condition precedent to the Closing of the transactions contemplated in this
Agreement (unless the failure of Purchaser's Affiliate is directly and solely
caused by (y) the default of either Seller, as assignor pursuant to the terms of
the Unit Two Contract Assignment and Assumption Agreement, or (z) the default by
seller under the Unit Two Contract pursuant to the terms of the Unit Two
Contract or its failure to convey title as set forth in such contract), and
(iii) Seller not being the subject of any pending voluntary or involuntary
reorganization, liquidation, receivership or other insolvency proceedings under
any federal, state, foreign or local bankruptcy, insolvency, liquidation,
reorganization or similar type laws.

         (b) The obligation of Seller to consummate the transactions hereunder
shall be contingent upon (i) Purchaser's delivery of the Purchase Price and the
documents and instruments required to be delivered by Purchaser pursuant to
SECTIONS 10(b) and 10(c), (ii) the simultaneous closing of the transactions
under the Unit Two Contract Assignment and Assumption Agreement (including the
assignment of the Unit Two Contract to Purchaser's Affiliate; PROVIDED THAT the
failure of Purchaser's Affiliate to close such transaction shall not excuse
Purchaser's performance hereunder and shall not form the basis of any claim or
assertion by Purchaser of a failure of a condition precedent to Closing, unless
the failure of Purchaser's Affiliate is directly and solely caused by (y) the
default of either Seller, as assignor pursuant to the terms of the Unit Two
Contract Assignment and Assumption Agreement, or (z) the default by seller under
the Unit Two Contract pursuant to the terms of the Unit Two Contract or its
failure to convey title as set forth in such contract, and (iii) Purchaser not
being the subject of any pending voluntary or involuntary reorganization,
liquidation, receivership or other insolvency proceedings under any federal,
state, foreign or local bankruptcy, insolvency, liquidation, reorganization or

         (c) Each of Seller and Purchaser expressly acknowledges and agrees
that, subject to satisfaction of the conditions set forth in SUBSECTIONS 12(a)
and 12(b), and subject to the provisions of SECTIONS 16, 17 and 18, (i) it is
absolutely and unconditionally obligated to fulfill its respective obligation to
convey and acquire the Unit in the manner contemplated by this Agreement, (ii)
it is absolutely and unconditionally obligated to otherwise close the
transactions in the time and manner contemplated by this Agreement and (iii)
this Agreement is not subject to

                                       40

foregoing and notwithstanding any mention of Purchaser's lender or lenders in
this Agreement, Purchaser's obligations hereunder shall not under any
circumstances be contingent on Purchaser obtaining financing or any lender or
investor funding all or any portion of the Purchase Price or other sums, whether
due hereunder or otherwise.

         13. CLOSING DATE.

         (a) The Closing Date shall be a date mutually satisfactory to the
parties but not later than March 14, 2001, TIME BEING OF THE ESSENCE in any and
all circumstances. Without limitation of the immediately preceding sentence, the
Closing Date may be postponed (i) by Purchaser by written notice made to Seller
on or before February 21, 2001, to March 20, 2001, TIME BEING OF THE ESSENCE,
unless Purchaser exercises its further extension rights as set forth in SECTION
13(b), in which case, the Closing Date may be postponed in accordance with
SECTION 13(b), (ii) by Seller if the closing under the Unit Two Contract is
postponed pursuant to Section 16(b) of such Contract or otherwise (subject to
the limitations set forth in SECTION 12(a)(ii)), or (iii) by Seller, if in the
exercise of Seller's reasonable judgment, it determines that it will be unable
to satisfy the Mandatory Estoppel Condition by the Closing Date, to a date not
later than April 30, 2001 (the "OUTSIDE CLOSING DATE"); PROVIDED, HOWEVER, that
if the Closing Date had theretofore been adjourned by Seller pursuant to this
CLAUSE (iii), Seller shall have the right on not less than fifteen (15) business
days prior written notice to accelerate the Outside Closing Date to a date
specified in such notice that is not earlier than March 20, 2001 (or to such
later date to which Purchaser may have theretofore postponed the Closing Date).
Under no circumstances shall Seller be obligated to postpone the Closing Date if
Seller determines that it is or may be unable to satisfy the Mandatory Estoppel
Condition on or before the Closing Date.

         (b) If Purchaser exercised its right to postpone the Closing Date
pursuant to SECTION 13(a)(i), Purchaser may, by written notice made not later
than February 27, 2001 and the indefeasible payment to Seller of an extension

preceding sentence, Purchaser may, by written notice made not later than March
6, 2001 and the indefeasible payment to Seller of an additional extension fee of
$250,000, postpone the Closing Date to April 25, 2001, TIME BEING OF THE
ESSENCE. Seller shall be entitled to retain the aforementioned extension fees
whether or not the Closing actually occurs, the parties agreeing that such fees
represent fair and adequate consideration paid for Seller's Agreement to permit
Purchaser to postpone the Closing.

         (c) The Closing of the transactions contemplated hereby shall take
place at 10:00 A.M. on the Closing Date, at (i) Seller's option, either at the
offices of O'Melveny & Myers LLP, 153 East 53rd Street, New York, New York
10022, of the offices of Paul, Hastings, Janofsky & Walker LLP, 75 East 55th
Street, New York, New York 10022 or (ii) if required by Purchaser's lender, if
any, at the offices of such Purchaser's lender or such lender's counsel in
Midtown Manhattan.

         14. VIOLATIONS.

                                       41


         (a) Except as provided in SECTION 14(b), all notices of violations of
laws or governmental ordinances, rules, regulations, orders or requirements
(collectively, "LAWS") issued by any governmental authority having jurisdiction
over the Unit and that relate to the period of time prior to the Closing Date
shall be the responsibility of Seller irrespective of whether or not notices of
such violations are issued or noted prior to the Closing Date and irrespective
of whether or not actually received by Seller prior to the Closing Date. Any
such notices of violations that are actually received by Seller prior to the
Closing Date shall be removed or complied with by Seller on or before the
Closing Date. Notwithstanding the foregoing provisions of this SECTION 14(a) to
the contrary, if such removal or compliance has not been completed on or before
the Closing Date, Seller may elect to either (i) deliver an undertaking to
Purchaser at Closing to diligently cause such violations to be removed
post-Closing or (ii) pay to Purchaser at the Closing (or credit Purchaser at
Closing as an adjustment to the Purchase Price payable to Seller pursuant to
SECTION 3 of this Agreement) an amount sufficient, in the reasonable judgment of
Seller and Purchaser, to pay for the performance of the work and provision of
the materials necessary to effect or complete such removal or compliance, and
upon Seller making such payment or giving such credit, Purchaser shall be
required to accept title to the Unit subject to such notices of violations and
(except for notices of violations of Laws that are issued by any governmental
authority having jurisdiction over the Unit and that relate to the period of
time prior to the Closing Date but are not actually received by Seller prior to
the Closing Date) Seller shall have no further obligation to remove or comply
with such notices of violations. Purchaser shall deliver to Seller copies of any
notices of violations of Laws that are issued by any governmental authority
having jurisdiction over the Unit that are received by Purchaser after the
Closing Date but that relate to the period of time prior to the Closing Date and
Seller shall, subject to the provisions of this SECTION 14, diligently cause
such notices to be removed or complied with.

         (b) Notwithstanding anything in this SECTION 14 to the contrary, Seller
shall not be obligated to remove or comply with any notices of violations to the
extent such notices relate to any of the following violations:

                  (i)     Any violation that is the obligation of any tenant or
         other occupant under a Lease in effect at the Closing to remedy, it
         being understood that, until the Closing Date, Seller shall use
         commercially reasonable good faith efforts to cause such tenant or
         other occupant to remedy the same; and

                  (ii)    Any violations relating to the sidewalks abutting
         Citigroup Center or relating to the Common Elements (except to the
         extent that such violations relate to matters within the reasonable
         control of Seller PROVIDED THAT Purchaser cooperates with Seller in
         connection therewith to the extent reasonably requested by Seller), it
         being understood that, until the Closing Date, Seller shall use its
         commercially reasonable good faith efforts to cause the Board of
         Managers to remedy or commence to remedy the same.

Purchaser shall accept title to the Unit subject to all violations not required
to be removed pursuant to this SECTION 14.

                                       42


         (c) The provisions of this SECTION 14 shall survive the Closing for a
period of two (2) years.

         15. NOTICES.

Each party may designate a change of address (or additional or substitute
parties for notice) by notice to the other party, given at least fifteen (15)
days before such change of address is to become effective.

         16. CASUALTY.

         (a) If during the Interim Period there shall occur a fire or other
casualty resulting in the damage or destruction of fifty percent (50%) or more
of the floor space of Citigroup Center (a "MAJOR CASUALTY"), either party shall
have the right, exercisable by giving written notice to the other within ten
(10) days after receiving written notice of such fire or other casualty, to
terminate this Agreement, in which case neither party shall have any further
rights or obligations hereunder except such obligations which expressly survive
the termination of this Agreement. If either party elects to terminate this
Agreement, all agreements with respect to the Unit Two Assignment and Assumption
Agreement shall automatically be terminated. If, between the date hereof and the
Closing, there shall occur a fire or other casualty affecting all or any part of
the Unit or any other portion of Citigroup Center other than a Major Casualty,
neither Seller nor Purchaser shall have the right to terminate this Agreement,
and in such event, or in the event of a Major Casualty as to which neither party
shall have exercised the termination option contained in the first sentence of
this SECTION 16(a), then (i) the parties shall proceed to the Closing without
reduction of or offset against any amounts payable hereunder or any other claim
against the other, (ii) at the Closing, Seller shall (y) pay over to Purchaser
the proceeds of any insurance collected by Seller less the amount of all costs
incurred by Seller in connection with the repair of such damage or destruction,
all of which costs incurred by Seller shall be a Purchaser Consent Action and
(z) assign and transfer to Purchaser, subject to the terms of the Condominium
Declaration, all right, title and interest of Seller in and to any uncollected
insurance proceeds that Seller may be entitled to receive from such damage or
destruction, and (iii) the parties hereto shall cooperate in all reasonable
respects in order to effectuate such intent. The provisions of this SECTION 16
shall survive the Closing for a period without expiration.

         (b) The parties hereto expressly intend that the provisions of this
SECTION 16 and not Section 5-1311 of the New York General Obligations Law shall
govern in the event of a fire or other casualty.

         17. CONDEMNATION.

         (a) If, between the date hereof and the Closing, fifty percent (50%) or
more (measured by square footage) of the floor space of Citigroup Center shall
be subject to a permanent taking or appropriation for public or quasi-public use
under the power of eminent domain or a condemnation proceeding (a "MAJOR
CONDEMNATION"), each of Purchaser and Seller shall have the right, exercisable
by giving written notice to the other within ten (10) days after receiving
written notice of such taking or appropriation, to terminate this Agreement, in

                                       44


which case neither party shall have any further rights or obligations hereunder
except such obligations which expressly survive the termination of this
Agreement. If, between the date hereof and the Closing, any condemnation or
eminent domain proceedings are initiated which would result in the taking of all
or any portion of the Unit, or any other portion of Citigroup Center other than
a Major Condemnation, neither Seller nor Purchaser shall have the right to
terminate this Agreement. In such event, or in the event of a Major Condemnation
as to which neither party shall exercise the termination option contained in the
first sentence of this subsection, then (i) the parties shall proceed to the
Closing without reduction of or offset against any amounts payable hereunder or
any other claim against the other, (ii) at the Closing, Seller shall assign and
turn over, and Purchaser shall be entitled to receive and keep any condemnation
proceeds in respect thereof, subject to the terms of the Condominium
Declaration, and (iii) the parties hereto shall cooperate in all reasonable
respects in order to effectuate such intent. The provisions of this SECTION 17
shall survive the Closing for a period without expiration.

         (b) The parties hereto expressly intend that the provisions of this
SECTION 17 and not Section 5-1311 of the New York State General Obligations Law,
shall govern in the event of a taking.

         18. REMEDIES.

         (a) If on or prior to the Closing Date, (i) Purchaser is in default of
any of its material obligations hereunder, or (ii) the Closing otherwise fails
to occur by reason of Purchaser's failure or refusal to perform its obligations
hereunder in a prompt and timely manner or Purchaser's Affiliate's failure or
refusal to perform its obligations under the Unit Two Assignment and Assumption
Agreement in a prompt and timely manner, then Seller may elect to either (y)
terminate this Agreement by written notice to Purchaser, or (z) proceed to close
the transactions contemplated herein. If this Agreement is so terminated, then
Seller shall be entitled to the Deposit and may request that Escrow Agent
deliver the Deposit to Seller pursuant to the terms of SECTION 24, whether held
as cash or as a Letter of Credit, as liquidated damages, and thereafter neither
party to this Agreement shall have any further rights or obligations hereunder
other than any arising under any Section herein that expressly provides that it
survives the termination of this Agreement.

         (b) If at the Closing, (i) Seller is in default of any of its material
obligations hereunder, or (ii) the Closing otherwise fails to occur by reason of
Seller's failure or refusal to perform its obligations hereunder in a prompt and
timely manner, then Purchaser may elect, as its sole and exclusive remedy, to
(x) terminate this Agreement by written notice to Seller, promptly after which
the Deposit shall be returned to Purchaser, (y) waive the condition or event in
question and proceed to close the transactions contemplated herein, or (z) seek
specific performance of the condition of event in question. As a condition
precedent to Purchaser exercising any right it may have to bring an action for
specific performance hereunder, Purchaser must commence such an action within
thirty (30) days after the occurrence of Seller's default. Purchaser agrees that
its failure to timely commence such an action for specific performance within
such thirty (30) day period shall be deemed a waiver by it of its right to
commence an action for specific performance as well as a waiver by it of any
right it may have to file or record a notice of lis pendens or notice of
pendancy of action or similar notice against any portion of the Unit.

                                       45


         (c) Nothing in this SECTION 18 shall be deemed to limit the rights and
remedies of the parties set forth in SECTION 11(d) for the breach of a
representation or warranty, subject to the provisions of SECTION 11(f).

         19. INDEMNITIES.

         (a) SELLER'S INDEMNITY. Seller hereby agrees to indemnify Purchaser and
the other Purchaser Indemnified Parties against, and to hold Purchaser and the
other Purchaser Indemnified Parties harmless from, all claims, demands, causes
of action, losses, damages, liabilities, costs and expenses (including
reasonable attorneys' fees and disbursements) asserted against or incurred by
Purchaser or any of the other Purchaser Indemnified Parties in connection with
or arising out of (i) acts or omissions of Seller or Seller's Representatives,
or other matters or occurrences that take place before the Closing and relate to
the ownership, maintenance or operation of the Unit that could not be
discoverable by a prospective purchaser in the prudent conduct of due diligence
in connection with a transaction such as the one contemplated hereby (except to
the extent caused by Purchaser's veto of any matter that is submitted to
Purchaser as a Purchaser Consent Action) including all losses, costs, damages
and expenses incurred by Purchaser and the other Purchaser Indemnified Parties
arising from audits performed by current or former tenants of the Unit relating
to escalations and pass-throughs charged by Seller prior to the Closing, (ii) a
breach of any material representation, warranty or covenant of Seller contained
in this Agreement or (iii) the breach of any material representation, warranty
or covenant of Seller, as purchaser, contained in the Unit Two Contract.
Seller's obligations under this SECTION 19(a) shall survive the Closing for a
period of one (1) year. Notwithstanding the foregoing, if a Breach Claim related
to a representation made by Seller under this Agreement had been commenced prior
to the expiration of the such one (1) year period and is still pending on such
date, Seller's obligations with respect solely to the representation underlying
the Breach Claim shall survive the Closing until the expiration of the Net Worth
Retention Period applicable to such Breach Claim.

         (b) PURCHASER'S INDEMNITY. Purchaser hereby agrees to indemnify Seller
and the other Seller Indemnified Parties against, and to hold Seller and the
other Seller Indemnified Parties harmless from, all claims, demands, causes of
action, losses, damages, liabilities, costs and expenses (including reasonable
attorneys' fees and disbursements) asserted against or incurred by Seller or any
of the other Seller Indemnified Parties in connection with or arising out of (i)
acts or omissions of Purchaser or Purchaser's Representatives, or other matters
or occurrences that take place after the Closing and relate to the ownership,
maintenance or operation of the Unit, or (ii) a breach of any material
representation, warranty or covenant of Purchaser contained in this Agreement.
Purchaser's obligations under this SECTION 19(b) shall survive the Closing for a
period of one (1) year. Notwithstanding the foregoing, if a Breach Claim related
to a representation made by Seller is still pending upon the expiration of such
one (1) year period, Purchaser's obligations with respect to its representation
in SECTION 11(b)(iv) (or any similar representation in any other document) as
the same relates to the Breach Claim shall survive the Closing until the
expiration of the Net Worth Retention Period applicable to the Breach Claim in
question.

         (c) NOTICE OF CLAIMS TO BE INDEMNIFIED. Whenever in this Agreement it
is provided that any party shall indemnify and hold harmless the other party,
then, as a condition to

                                       46


such indemnity the terms of this SECTION 19(c) shall apply. The party
indemnified shall promptly give written notice to the indemnitor of any claim or
demand made upon it is or may be indemnified against. The indemnitor shall have
the right to defend against such claim or demand by counsel selected by
indemnitor's liability insurer or such other counsel selected by indemnitors, in
any case, and reasonably satisfactory to the indemnified party. The indemnified
party shall reasonably cooperate with indemnitor, at indemnitor's expense. The
indemnified party shall not settle or approve the settlement of any claim
without the approval of the indemnitor, which approval shall not be unreasonably
withheld or delayed. Any separate counsel retained by the indemnified party
shall be at its own expense.

         20. ASSIGNMENT AND RECORDING.

         (a) Except as set forth in the next succeeding sentence, neither this
Agreement nor any of the rights or obligations hereunder may be assigned without
the prior written consent of the other party hereto, which consent may be
withheld in either party's sole discretion. Notwithstanding the foregoing,
Seller shall have the right, at any time after the Closing Date, to assign its
obligations under this Agreement to any United States Person that is a direct or
indirect affiliate of Seller PROVIDED such Person agrees to (i) assume all of
Seller's obligations hereunder, (ii) designate a registered agent in New York to
receive service of process, and (iii) maintain the requisite Minimum Net Worth
for the requisite time period.

         (b) Neither this Agreement nor any memorandum of this Agreement may be
recorded without the prior written consent of the parties hereto, which may be
withheld in either party's sole discretion.

         21. PROPERTY INFORMATION AND CONFIDENTIALITY.

         (a) Each of Seller and Purchaser (for purposes of this SECTION 21, each
a "CONFIDENTIAL PARTY") agrees that, prior to the Closing, all Property
Information shall be kept strictly confidential and shall not, without the prior
consent of the other, be disclosed by such Confidential Party or such
Confidential Party's Representatives, in any manner whatsoever, in whole or in
part, and will not be used by such Confidential Party or such Confidential
Party's Representatives, directly or indirectly, for any purpose other than
evaluating and consummating the transactions contemplated by this Agreement.
Moreover, each Confidential Party agrees that without limitation of any
obligation on the part of Purchaser or any Person by or through Purchaser or any
so-called "Requestor Party" as set forth in the Confidentiality Agreement, prior
to the Closing, the Property Information will be transmitted only to such
Confidential Party's Representatives who need to know the Property Information
for the purpose of evaluating the transactions contemplated by this Agreement or
the financing thereof, and who are informed by such Confidential Party of the
confidential nature of the Property Information. The provisions of this SECTION
21 shall in no event apply to Property Information that is a matter of public
record and shall not prevent a Confidential Party from complying with any laws
or governmental ordinances, rules, regulations, orders or requirements,
including governmental regulatory, disclosure, tax and reporting requirements.

         (b) Each of Seller and Purchaser, for the benefit of the other, hereby
agrees that between the date hereof and the Closing Date, it will not release or
cause or permit to be released

                                       47


any press notices, publicity (oral or written) or advertising promotion relating
to, or otherwise announce or disclose or cause or permit to be announced or
disclosed, in any manner whatsoever, the terms, conditions or substance of this
Agreement or the transactions contemplated herein, without first obtaining the
written consent of the other party hereto, which consent shall not be
unreasonably withheld, conditioned or delayed. It is understood that the
foregoing shall not preclude Seller or Purchaser from discussing the substance
or any relevant details of the transactions contemplated in this Agreement,
subject to the terms of SECTION 21(a) and the Confidentiality Agreement, with
any of its attorneys, accountants, professional consultants or potential
lenders, as the case may be, or prevent Seller or Purchaser from complying with
any laws or governmental ordinances, rules, regulations, orders or requirements,
including governmental regulatory, disclosure, tax and reporting requirements.

         (c) Without limitation of anything to the contrary in the
Confidentiality Agreement, if this Agreement is terminated, each Confidential
Party and such Confidential Party's Representatives shall promptly deliver to
the other party to this Agreement all originals and copies of the Property
Information referred to in SECTION 21(d)(i) in the possession of such
Confidential Party and such Confidential Party's Representatives.

         (d) As used in this Agreement, the term "PROPERTY INFORMATION" shall
mean (i) all information and documents in any way relating to the Unit, the
operation thereof or the sale thereof (including Leases and Contracts) furnished
to, or otherwise made available for review by, a Confidential Party or its
Representatives, by the other party to this Agreement, or any of such other
party's affiliates, or their agents or representatives, including, without
limitation, their contractors, engineers, attorneys, accountants, consultants,
brokers or advisors, and (ii) all analyses, compilations, data, studies, reports
or other information or documents prepared or obtained by a Confidential Party
or such Confidential Party's Representatives containing or based, in whole or in
part, on the information or documents described in the preceding CLAUSE (i).

         (e) The provisions of this SECTION 21 shall survive the termination of
this Agreement and the Closing.

         22. ERISA.

         Purchaser represents and warrants to Seller that Purchaser is not an
employee benefit plan or a governmental plan, or a party in interest of either
of such plans, and that the funds being used to acquire the Unit are not plan
assets or subject to state laws regulating investment of, and fiduciary
obligations with respect to, a governmental plan. As used in this SECTION 22,
the terms "employee benefit plan," "party in interest," "plan assets" and
"governmental plan" shall have the respective meanings assigned to them in the
Employee Retirement Income Security Act of 1974, as amended, and the Regulations
promulgated in connection therewith. The representations and warranties
contained in this SECTION 22 shall survive the Closing for a period without
expiration.

                                       48


         23. SURVIVAL.

         Except as otherwise expressly provided in this Agreement, no
representations, warranties, covenants or other obligations of Seller or
Purchaser set forth in this Agreement shall survive the Closing (the last day of
any applicable survival period pertaining to any particular representation,
warranty, covenant or other obligation set forth in any provision of this
Agreement being a "SURVIVAL TERMINATION DATE"), and no action or proceeding
based upon any such representation, warranty, covenant or other obligation that
survives the Closing shall be commenced after the applicable Survival
Termination Date, if any.

         24. ESCROW.

         (a) The Deposit, together with any interest earned thereon, shall be
held by Escrow Agent, in trust, and disposed of only in accordance with the
following provisions:

                  (i)     Escrow Agent shall invest the Deposit, if converted to
         cash pursuant to SUBSECTION 24(d)(v)(z), in an interest-bearing
         account, and shall not commingle the Deposit with any funds of Escrow
         Agent or others. Escrow Agent shall not be obligated to achieve any
         particular return on the Deposit nor shall it be liable for any loss as
         a result of the action or inaction of the depository institution.

                  (ii)    If the Closing occurs, Escrow Agent shall deliver the
         Deposit, if the same is then held as cash, to or upon the instructions
         of Seller on the Closing Date. If the Deposit is held as a Letter of
         Credit, then on the Closing Date Escrow Agent shall return the Letter
         of Credit to Purchaser.

                  (iii)   If for any reason the Closing does not occur, Escrow
         Agent shall deliver the Deposit (and all interest earned thereon if the
         same is then held in cash) to Seller or Purchaser only upon receipt of
         a written demand therefor from such party, subject to the following
         provisions of this SUBSECTION 24(a)(iii) or of SUBSECTION 24(d), as
         applicable. If for any reason the Closing does not occur and Escrow
         Agent receives a written demand for payment of the Deposit (and all
         interest earned thereon if the same is then held in cash) or a written
         demand for delivery of the Letter of Credit, as the case may be, Escrow
         Agent shall give written notice to the other party of such demand. If
         Escrow Agent does not receive a written objection from the other party
         to either the proposed payment or the proposed delivery of the Letter
         of Credit within ten (10) days after the giving of such notice, Escrow
         Agent is hereby authorized to make such payment or deliver the Letter
         of Credit to the party making the demand. If Escrow Agent does receive
         such written objection within such period, Escrow Agent shall continue
         to hold the Deposit until otherwise directed by written instructions
         signed by Seller and Purchaser or a final judgment of a court, or may,
         at its option, deposit the same with a court of competent jurisdiction.
         If the Closing does not occur by a date that is thirty (30) days or
         fewer prior to the expiration date of the Letter of Credit and no
         replacement Letter of Credit has theretofore been delivered to Escrow
         Agent, Seller shall be entitled to make a written demand upon Escrow
         Agent (or the court which is holding the Letter of Credit if the same
         had theretofore been deposited with a court) for delivery of the Letter
         of Credit for the purposes of drawing upon the same pursuant to SECTION
         24(d) and Escrow Agent or such court, as the case may be, shall be
         entitled to act in accordance with such demand without providing notice
         thereof to Purchaser.

                                       49


         (b) The parties acknowledge that Escrow Agent (i) may represent Seller
in the matters contemplated in this Agreement notwithstanding its acting as an
escrow agent, (ii) is acting solely as a stakeholder at the request of the
parties and for their convenience, (iii) shall not be deemed to be the agent of
either of the parties, and (iv) shall not be liable to either of the parties for
any action or omission on its part taken or made in good faith, and not in
willful or grossly negligent disregard of this Agreement. Seller and Purchaser
shall jointly and severally indemnify and hold Escrow Agent harmless from and
against all costs, claims and expenses, including reasonable attorneys' fees,
incurred in connection with the performance of Escrow Agent's duties hereunder,
except with respect to actions or omissions taken or made by Escrow Agent in bad
faith, in willful disregard of this Agreement or involving gross negligence on
the part of Escrow Agent.

         (c) Purchaser shall pay any income taxes on any interest earned on and
any other income derived from the Deposit. Purchaser's taxpayer identification
number is pending. Purchaser shall obtain its taxpayer identification number
prior to the Closing and provide the same to Seller and Escrow Agent.

         (d) The Letter of Credit delivered as the Deposit pursuant to SECTION
2.2 shall (i) be delivered to Escrow Agent, (ii) be payable to Seller as
beneficiary, (iii) have an expiration date not earlier than June 15, 2001, (iv)
be in a face amount of the Deposit, (v) be drawable by Seller upon presentation
to the issuer of a writing signed by a duly authorized officer of Seller stating
either that (y) the beneficiary is entitled to receipt of the Deposit pursuant
to the terms of this Agreement or (z) the Letter of Credit will expire within
thirty (30) days of the date on which the drawing is made and no replacement
Letter of Credit has been delivered to Escrow Agent, and (vi) shall constitute
an irrevocable obligation by the issuer to make payment to Seller in the full
amount outstanding under such Letter of Credit upon receipt of a writing
described in CLAUSE (v). If Seller draws upon the Letter of Credit in the
circumstances described in CLAUSE (z), Seller shall be obligated to deliver the
proceeds thereof to Escrow Agent, who, promptly upon receipt, will hold the same
as if the Deposit were made in cash pursuant to the terms of this Agreement.

         (e) Escrow Agent has executed this Agreement in the place indicated on
the signature pages hereof in order to confirm that Escrow Agent has received
the Letter of Credit and shall hold the Letter of Credit until the Closing or
demand is made upon Escrow Agent for the Letter of Credit pursuant to this
SECTION 24.

         25. MISCELLANEOUS PROVISIONS.

         (a) ENTIRE AGREEMENT. This Agreement and each of the Exhibits and
Schedules, contains all of the terms agreed upon between the parties with
respect to the subject matter hereof and supersedes all prior agreements or
understandings between the parties with respect to the matters contained herein.
The parties hereto acknowledge that no oral or other agreements, understandings,
representations or warranties exist with respect to this Agreement or with
respect to the obligations of the parties hereto under this Agreement, except
those specifically set forth in this Agreement.

         (b) AMENDMENTS. This Agreement may not be changed, modified or
terminated, except by an instrument executed by the parties hereto.

                                       50


         (c) RIGHTS CUMULATIVE; WAIVERS. The rights of each of the parties under
this Agreement are cumulative and may be exercised as often as any party
considers appropriate. The rights of any of the parties hereunder shall not be
capable of being waived or varied otherwise than by an express waiver or
variation in writing executed by all of the parties hereto. Failure to exercise
or any delay in exercising any of such rights also shall not operate as a waiver
or variation of that or any other such right. Defective or partial exercise of
any of such rights shall not preclude any other or further exercise of that or
any other such right. No act or course of conduct or negotiation on the part of
any party shall in any way preclude such party from exercising any such right or
constitute a suspension or any variation of any such right.

         (d) PARTIAL INVALIDITY. If any term or provision of this Agreement or
the application thereof to any Person or circumstance shall, to any extent, be
invalid or unenforceable, the remainder of this Agreement, or the application of
such term or provision to persons or circumstances other than those as to which
it is held invalid or unenforceable, shall not be affected thereby, and each
term and provision of this Agreement shall be valid and be enforced to the
fullest extent permitted by law.

         (e) Intentionally Omitted.

         (f) (i) All matters in dispute in respect of this Agreement, all claims
of breach of any representation herein that survive the Closing, and any claim
against Seller alleging a breach of a representation in a Seller's Certificate
shall be resolved by arbitration and commenced by filing and serving upon the
party a statement of claim in arbitration setting forth with particularity (A)
the details of the claim, (B) the damages alleged and (C) detailed information
supporting such damages (any such dispute or claim commenced in such a manner, a
"BREACH CLAIM"). The arbitration process and proceeding described in this
SECTION 25(f) is referred to herein as "EXPEDITED ARBITRATION".

                  (ii)    If the parties shall not have agreed on a choice of an
         arbitrator within twenty (20) days after the service of such statement
         of claim in arbitration, then each party shall, within ten (10) days
         thereafter appoint an arbitrator, and advise the other party of the
         arbitrator so appointed. A third arbitrator shall, within ten (10) days
         following the appointment of the two (2) arbitrators, be appointed by
         the two arbitrators so appointed or by the AAA, if the two arbitrators
         are unable, within such ten (10) day period, to agree on the third
         arbitrator. If either party fails to appoint an arbitrator (herein
         called the "FAILING PARTY"), the other party shall provide an
         additional notice to the Failing Party requiring the Failing Party's
         appointment of an arbitrator within ten (10) days after the Failing
         Party's receipt thereof. If the Failing Party fails to notify the other
         party of the appointment of its arbitrator within such ten (10) day
         period, the appointment of the second arbitrator shall be made by the
         AAA in the same manner as hereinabove provided for the appointment of a
         third arbitrator in a case where the two arbitrators appointed
         hereunder are unable to agree upon such appointment. In the absence,
         failure, refusal or inability of the AAA to act within twenty (20)
         days, then either party, on behalf of both, may apply to a Justice of
         the Supreme Court of New York, New York County, for the appointment of
         the third arbitrator, and the other party shall not raise any question
         as to the court's full power and jurisdiction to entertain the
         application and make the appointment on an expedited basis. The three
         (3) arbitrators shall render a resolution of

                                       51


         such dispute or make the determination in question. In the event of the
         absence, failure, refusal or inability of an arbitrator to act, a
         successor shall be appointed within ten (10) days as hereinabove
         provided. Any arbitrator acting under this SECTION 25(f) shall have not
         less than ten (10) years' continuous experience before the date of
         appointment relating to the leasing, management or operation of
         commercial office space in Class A buildings in Manhattan.

                  (iii)   All arbitrators chosen or appointed pursuant to this
         SECTION 25(f) shall (A) be sworn fairly and impartially to perform
         their respective duties as such arbitrator, (B) not be an employee or
         past employee or present or past director or partner, consultant or

Closing for a period without expiration.

         (k) TENANT ESTOPPELS. (i) Seller shall deliver to each tenant under a
Lease in the Unit a proposed estoppel certificate in the form of its respective
Requested Estoppel Form and Seller shall exercise reasonable good faith efforts
to cause such tenants to furnish executed Approved Estoppels; PROVIDED, HOWEVER,
in no event shall Seller be obligated to obtain executed estoppel certificates
from any such tenant except as set forth in the balance of this SECTION 25(k).
Seller will use good faith efforts to obtain cooperation from Citibank, N.A. to
deliver to each

                                       53


tenant under a lease in Unit Two (other than Citibank, N.A.) a proposed estoppel
certificate in the form of its respective Requested Estoppel Form and to
exercise good faith efforts to cause such tenants to furnish executed Approved
Estoppels; PROVIDED, HOWEVER, that in no event shall Seller be obligated to
obtain executed estoppel certificates from any tenant of Unit Two (other than
Citibank, N.A.).

                  (ii)    As a condition to Closing, (the "MANDATORY TENANT
         COVERAGE CONDITION"), Seller shall be obligated to (x) deliver (A) the
         Unit One Citibank Estoppel, (B) a Specific Tenant Estoppel from
         Citibank, N.A. with respect to its lease for office space in Unit Two
         to be executed on the Closing Date, the form of which is attached as an
         Exhibit to the Unit Two Contract, (C) an Approved Estoppel from
         O'Melveny & Myers, LLP, (D) an Approved Estoppel from Jones Lang
         LaSalle Management Services, Inc., (E) an Approved Estoppel from
         Kirkland & Ellis; (F) an Approved Estoppel from A.T. Kearney, Inc., (G)
         an Approved Estoppel from Ziff Brothers Investments, Inc., and (H) an
         Approved Estoppel from Schlumberger Limited (the estoppel certificates
         referred to in CLAUSES (A) through (H), collectively, the "MAJOR TENANT
         ESTOPPELS"), (y) Approved Estoppels from sufficient tenants of the Unit
         and Unit Two such that Seller shall have delivered to Purchaser
         Approved Estoppels, when also taking into account the Major Tenant
         Estoppels, covering at least 75% of the net rentable square feet in the
         Building (Approved Estoppels from tenants whose demised premises
         collectively comprise 75% of the net rentable square feet of the
         Building inclusive of Major Tenant Estoppels, is the "MANDATORY
         ESTOPPEL CONDITION"); and (z) Approved Estoppels from other tenants of
         the Unit and/or Unit Two whose demised premises comprise an additional
         10% of the net rentable square footage of the Building; PROVIDED,
         HOWEVER, that Seller may satisfy all or any part of its obligations
         under this CLAUSE (Z) by providing Seller's Certificates covering
         Leases of such other tenants of the Building, as Seller shall determine
         in its sole discretion. If at any time and from time to time hereafter,
         Seller receives an Approved Estoppel from any tenant with respect to
         whose lease a Seller's Certificate was delivered, Seller shall have the
         right to deliver the same to Purchaser and upon such delivery, such
         Seller's Certificate shall be automatically void.

                  (iii)   If Seller receives from any tenant an executed
         estoppel reflecting modifications to such tenant's Requested Estoppel
         Form that might disqualify the certificate as an Approved Estoppel,
         Seller shall promptly deliver the same to Purchaser. Purchaser shall,
         within two (2) business days of receipt of any estoppel delivered to
         it, advise Seller whether such estoppel certificate is acceptable and
         would therefore constitute an Approved Estoppel or is rejected and
         shall not be considered an Approved Estoppel. Any rejection of a tenant
         estoppel certificate as aforesaid shall be done in a writing delivered
         to Purchaser that briefly describes the reasons for such rejection. If
         Purchaser does not indicate rejection of an estoppel certificate
         delivered to it within such two (2) business day period, it will
         automatically be deemed acceptable and shall constitute an Approved
         Estoppel.

                  (iv)    Purchaser's sole and exclusive remedy for Seller's
         failure to satisfy the Mandatory Tenant Coverage Condition on or before
         the Closing Date will be to terminate this Agreement and receive a
         return of the Deposit. Nothing herein shall limit any rights or
         remedies Purchaser may have under this Agreement, under applicable Laws
         or otherwise if it is determined by arbitrators pursuant to Expedited
         Arbitration that Seller failed to exercise

                                       54


         reasonable good faith efforts to cause tenants to furnish Approved
         Estoppels pursuant to SECTION 25(k)(i).

                  (v)     The provisions of this SECTION 25(k) shall survive the
         Closing or the earlier termination of this Contract for a period
         without expiration.

         (l) TENANT SNDAS. Seller shall deliver to each of (i) Citibank, N.A.
(in respect of its Lease of space in Unit One), (ii) Citibank, N.A. (in respect
of its proposed Lease for office space in Unit Two to be executed on the Closing

Services, Inc., a proposed subordination, non-disturbance and attornment
agreement in the form of its respective Requested SNDA Form, and Seller shall
exercise reasonable good faith efforts to cause such tenants to furnish their
respective Approved SNDAs on or before the Closing Date. Purchaser' sole and
exclusive remedy for Seller's failure to deliver Approved SNDAs executed by each
of the tenants referred to in this SECTION 25(l) on or before the Closing Date
will be to terminate the Contract and receive a return of the Deposit.

         (m) COUNTERPARTS. This Agreement may be executed in several
counterparts, each of which shall constitute one and the same instrument and
either party hereto may execute this Agreement by signing any such counterpart.

         (n) WAIVER OF TRIAL BY JURY. THE PARTIES HERETO KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE (TO THE EXTENT PERMITTED BY APPLICABLE LAW) ANY RIGHT TO
A TRIAL BY JURY OF ANY DISPUTE ARISING UNDER OR RELATING TO THIS AGREEMENT AND
AGREE THAT ANY SUCH DISPUTE SHALL BE TRIED BEFORE A JUDGE SITTING WITHOUT A
JURY.

         (a) Purchaser represents and warrants that it has not dealt or
negotiated with any broker with respect to the transactions contemplated by this
Agreement other than Jones Lang LaSalle and LaSalle Investment Management, Inc.
(collectively, "JLL") and Salomon Smith Barney Inc. ("SSB") and Purchaser shall
pay all fees due to JLL in connection therewith pursuant to a separate
agreement. Purchaser shall indemnify, defend and hold Seller harmless, from and
against any and all loss, cost, damage, claim, liability and expense (including,
without limitation, reasonable attorneys' fees) resulting from a breach of the
foregoing representation and warranty.

         (b) Seller represents and warrants that it has not dealt or negotiated

hold Purchaser harmless, from and against any and all loss, cost, damage, claim,
liability and expense (including, without limitation, reasonable attorneys'
fees) resulting from a breach of the foregoing representation and warranty.

         (c) Purchaser shall be responsible for the payment of all professionals
and advisors retained by Purchaser in connection with the transactions
contemplated by this Agreement. Seller shall be responsible for the payment of
all professionals and

                                      -15-


advisors retained by Seller in connection with the transactions contemplated by
this Agreement.

         (d) The provisions of this Section 5 shall survive the Closing for a
period without expiration.

         6.  CUSTOMARY CLOSING ADJUSTMENTS.

         (a) The following are to be apportioned for the Unit as of the
Apportionment Date (subject to the rights of tenants under their Leases), and
shall (except as expressly set forth herein) constitute an adjustment with
respect to the Purchase Price as of the Apportionment Date:

                  (i)     real estate taxes, personal property taxes and all
         assessments (special and general) for the current tax fiscal period in
         progress on the Apportionment Date (it being agreed that the same shall
         be adjusted on an accrual basis). If the rate or amount of such taxes
         shall not be fixed prior to the Closing Date, the adjustment thereof as
         of the Apportionment Date shall be upon the basis of the rate for the
         preceding tax fiscal period applied to the latest assessed valuation
         (or, if none, other basis of valuation, including without limitation,
         written opinions of tax adjusters or as otherwise agreed to by Seller
         and Purchaser), and the same shall be further adjusted no later than
         thirty (30) days after the date on which the taxes for the current tax
         fiscal period in progress on the Apportionment Date are paid;

                  (ii)    unless final meter readings are obtained on the
         Apportionment Date (for which Seller shall be solely responsible),
         vault charges, water and sewer service charges, and charges for all
         other public utilities, including, without limitation, steam,
         electricity and gas (to the extent the Unit owner is responsible for
         the payment thereof). The rights to the return of any deposits with
         utility companies shall be retained by Seller. Purchaser shall promptly
         upon request of Seller put up any replacement deposit on or about the
         Closing Date which may be required by a utility company as a
         precondition to the release of Seller's deposit;

                  (iii)   base rents, fixed rents, additional rents, escalation
         rents, percentage rents and any other rents (exclusive of advance rents
         and security deposits) paid or payable for the billing period in
         progress as of the Apportionment Date in accordance with Section 8A of
         this Agreement; it being agreed that to the extent, on the
         Apportionment Date, additional rents, escalation rents, percentage
         rents or other rents have not been collected for such billing period,
         then each such item shall be adjusted retroactively to the
         Apportionment Date in

                                      -16-


         accordance with Section 8A and this Section 6 no later than thirty (30)
         days after each such item has been collected. Percentage rent, payments
         or reimbursements on account of operating expenses and real estate
         taxes, utility charges and any other payments, reimbursements or
         contributions by tenants under the Leases shall be prorated as follows:
         (y) with respect to percentage rents (if any), Purchaser shall furnish
         to Seller promptly upon receipt copies of all sales reports from
         tenants who owe percentage rent for any period prior to the
         Apportionment Date, whereupon the percentage rent due (if any) shall be
         promptly calculated and the proration between Seller and Purchaser
         computed as of the Apportionment Date; and (z) the amount of any other
         rents, payments, reimbursements or contributions to be made by any
         tenant shall be computed in accordance with such tenant's Lease as
         existing as of the Apportionment Date; and (provided that such tenant's
         rent payments are not in arrears) Purchaser shall remit to Seller
         Seller's pro rata portion of such percentage rents (if any) and any
         other rents, payments, reimbursements or contributions (based upon
         apportionment being made as of the Apportionment Date) promptly after
         such rents, payments, reimbursements or contributions have been
         collected by Purchaser from such tenant. If Seller has collected
         estimated amounts of prepayments in excess of the amounts properly
         payable under any tenant's Lease, (i) Seller shall promptly remit said
         excess to Purchaser after notice from Purchaser and after such excess
         is verified by a review or analysis of estimated prepayments in
         accordance with such tenant's Lease, (ii) Purchaser shall promptly
         remit to the applicable tenant any such excess paid over to Purchaser
         pursuant to the preceding clause (i), and (iii) Purchaser shall
         indemnify and hold Seller harmless from all claims, demands, causes of
         actions, losses, damages, liabilities, costs and expenses (including,
         without limitation, reasonable attorneys' fees and disbursements)
         asserted against or incurred by Seller in connection with or arising
         out of Purchaser's failure to fulfill its obligations pursuant to the
         preceding clause (ii) of this sentence;

                  (iv)    permit fees and license fees with respect to any
         assigned permits and licenses;

                  (v)     charges and payments under assignable Contracts (other
         than those terminated in accordance with Section 11(a)(x) of this
         Agreement) or permitted renewals or replacements thereof; and

                  (vi)    insurance premiums and other similar prepaid expenses
         (to the extent Purchaser retains the same), Common Charges and Limited
         Common Charges (as such terms are defined in the Condominium
         Declaration) and any Grand Central Partnership payments or dues
         applicable to the Unit, operating agreement payments (if such
         agreements are assumed by Purchaser) and such

                                      -17-


         other items that, in New York, New York, are customarily prorated,
         adjusted or paid in accordance with the "customs in respect to title
         closings" recommended by The Real Estate Board of New York, Inc., as
         amended and in effect on the date of Closing, in connection with the
         sale or exchange of property similar to the Unit, consistent with the
         terms and provisions of this Agreement.

         (b) All funds in any operating accounts, reserve accounts or any other
accounts pertaining to the Unit on the Apportionment Date, whether in the name
of Seller or any property manager of the Unit, shall (subject to the terms of
any applicable Leases and the adjustments required under this Agreement) be
retained by Seller or applied as Seller shall direct, and all cash, coins and
petty cash to which Seller is entitled (including, without limitation, cash in
coin operated machines, if any) located in the Unit shall be counted by Seller
or any such property manager on the Apportionment Date and the same shall be
retained by Seller or remitted to Seller by any such property manager.

         (c) The security deposits and advance rents with respect to the Leases
(together with any interest thereon required pursuant to the terms of the Leases
or applicable law) shall not be pro-rated, but instead shall be paid over to
Purchaser on the Closing Date, provided that, if such security deposits or
advance rents are in the possession or control of any property manager, at
Purchaser's request Seller shall direct such property manager in writing to
retain possession or control thereof for the benefit of Purchaser. Promptly
after the Closing (irrespective of when such Closing occurs), Seller shall
transfer or cause to be transferred to Purchaser any and all letters of credit
and Seller's interest in any certificates of deposit held by Seller as security
for a tenant's performance under any of the Leases being assigned to Purchaser.
If any such letter of credit is non-transferable, Seller shall use its good
faith efforts to have such letter of credit reissued in the name of Purchaser
(at Seller's sole cost and expense), and failing that, Seller agrees to continue
holding any such non-transferable letter of credit and agrees to present the
letter of credit for payment or to release the letter of credit on the written
instructions of Purchaser and will remit any funds collected thereunder to
Purchaser (less any reasonable costs of collection), provided that Seller is
indemnified and held harmless by Purchaser from and against any liability, cost
or expense as a result thereof.

         (d) INTENTIONALLY OMITTED.

         (e) UNANTICIPATED CAPITAL EXPENDITURES. Seller shall be responsible for
the payment of all Unanticipated Capital Expenditures incurred during the
Interim Period. If on the Closing Date any Unanticipated Capital Improvements
have not been completed and/or funded by Seller, then Purchaser shall receive a
credit at Closing in an amount equal to the amount of any such unfunded items
and the cost to complete any such unfunded work.

                                      -18-


         (f) LEASING COMMISSIONS, TENANT ALLOWANCES AND BUDGETED REPAIRS. Seller
and Purchaser shall each be responsible for the payment of those (i) Leasing
Commissions relating to Existing Leases and Approved New Leases allocable to
each such party as set forth on Schedule 6(f)(i) attached to this Agreement,
(ii) Tenant Allowances that are the obligation of the landlord under the
Existing Leases and the Approved New Leases allocable to each such party as set
forth on Schedule 6(f)(ii) attached to this Agreement and (iii) Budgeted Repairs
under Construction Contracts allocable to each such party as set forth on
Schedule 6(f)(iii) attached to this Agreement. If on the Closing Date any items
allocable to Seller on any of the foregoing Schedules 6(f)(i)-(iv) in respect of
Budgeted Repairs, Leasing Commissions or Tenant Allowances have not been
completed and/or funded by Seller, then Purchaser shall receive a credit at
Closing in an amount equal to the amount of any such unfunded items and the cost
to complete any such unfunded work.

         (g) INTENTIONALLY OMITTED.

         (h) SURVIVAL. Seller and Purchaser agree to use reasonable efforts to
calculate all adjustments required under this Section 6 with respect to those
items of income and expense that are ascertainable on the Apportionment Date by
no later than the sixty (60) days after the Apportionment Date. Each other item
of income and expense that is subject to adjustment under this Section 6 but
that is not ascertainable on the Apportionment Date will be adjusted retroactive
to the Apportionment Date, and the payment made on such adjustment within sixty
(60) days after the date that such adjustment becomes ascertainable (I.E., the
date by which each party, in its good faith business judgment, has sufficient
information to make such adjustment). The parties agree that each party shall
have the right, during the period commencing on the Closing Date and terminating
at the close of business on the one hundred eightieth (180th) day after the
Closing Date, on reasonable advance written notice to the other, from time to
time during regular business hours, to review the books and records of such
other party pertaining solely to the operations of the Unit to the extent
necessary to confirm the amounts of adjustments payable to Seller and/or
Purchaser following the Apportionment Date and in furtherance thereof the
parties shall, upon reasonable advance written notice, make their respective
books and records available for the other during regular business hours and
shall use their good faith commercially reasonable efforts to cause the managing
agent of the Common Elements to make available the applicable portion of its
books and records for such purpose. Seller and Purchaser shall cooperate as
necessary following the Closing Date in order to promptly and in good faith
discharge their respective obligations under this Section 6. Notwithstanding the
foregoing, any claim for an adjustment under Section 6(a) will be valid if made
in writing with reasonable specificity within one (1) year after the Closing
Date, except in the case of items of adjustment which at the expiration of such
period are subject to pending litigation or administrative proceedings. Claims
with respect to items of adjustment that are subject to litigation or
administrative proceedings will be valid if made on or before the later to occur
of (i) the date that is one (1) year after the Closing Date and (ii) the date
that is one hundred eighty (180) days after a final non-appealable order shall
have issued in such litigation

                                      -19-


or administrative hearing. Both parties shall use good faith efforts to resolve
any disputed claims promptly. The provisions of this Section 6 shall survive the
Closing. Purchaser shall notify, or shall cause any property manager retained by
it to notify, Seller of any reimbursement adjustment to which Seller becomes
entitled under the provisions of this Section 6 promptly after Purchaser or such
property manager determines that such reimbursement adjustment is due to Seller.

         7.  EFFECT OF CERTAIN LEASE EVENTS.

         (a) In addition to the Customary Adjustment being calculated as of the
Apportionment Date with respect to the Unit in accordance with the provisions of
Section 6 above and the adjustments set forth in Section 8A, the adjustments set
forth in this Section 7 shall, to the extent applicable, be made on the Closing
Date.

         (b) If a Contractual Right Lease Event occurs with respect to an
Existing Lease during the Interim Period, then (i) during the Interim Period,
Seller alone shall continue to be responsible for the payment of all costs and
expenses attributable to such Existing Lease (as adjusted for the effect of the
Contractual Right Lease Event) and Seller alone shall continue to be entitled to
the receipt of all income generated from such Existing Lease (as adjusted for
the effect of the Contractual Right Lease Event) and (ii) from and after the
Closing Date, Purchaser alone shall be responsible for the payment of all costs
and expenses attributable to such Existing Lease (as adjusted for the effect of
the Contractual Right Lease Event) and Purchaser alone shall be entitled to the
receipt of all income generated from such Existing Lease (as adjusted for the
effect of the Contractual Right Lease Event). If the Contractual Right Lease
Event results in an Adjusted NOI which exceeds the Pro Forma NOI (a "Positive
NOI Adjustment"), then the Positive NOI Adjustment shall inure to the benefit of
Seller from and after the occurrence of the Contractual Right Lease Event up to
and including the Apportionment Date. If the Contractual Right Lease Event
results in a Positive NOI Adjustment, then the Positive NOI Adjustment shall
inure to the benefit of Purchaser from and after the Closing Date. Conversely,
if a Contractual Right Lease Event occurs during the Interim Period and such
Contractual Right Lease Event results in an Adjusted NOI which is less than the
Pro Forma NOI (a "Negative NOI Adjustment"), then the Negative NOI Adjustment
shall be borne by Seller from and after the occurrence of the Contractual Right
Lease Event up to and including the Apportionment Date and shall be borne by
Purchaser from and after the Closing Date. Without limiting the generality of
the foregoing, if upon the occurrence of a Contractual Right Lease Event which
results in the termination of any Existing Lease, any fee or other payment
required to be made by the applicable tenant under such Existing Lease is in
fact paid during the Interim Period as a condition to the termination of such
Existing Lease, such fee or other payment shall belong exclusively to Seller.
Any subsequent re-leasing of the space (or any portion thereof) previously
demised under such terminated Existing Lease during the Interim Period shall
constitute a Purchaser Consent Action, subject to the provisions of Section
8(a)(i) of this Agreement, it being the intention of

                                      -20-


the parties that Purchaser shall ultimately bear all the risks and rewards of
such re-leasing; provided, however, (i) during the Interim Period, subject to
the following provisions of this Section, Seller alone shall be responsible for
the payment of all costs and expenses of re-leasing the space in question
(including, without limitation, all tenant improvement expenses, tenant
allowances, leasing commissions, referral fees and legal fees) and Seller alone
shall be entitled to the receipt of all income therefrom and (ii) from and after
the Closing Date, Purchaser alone shall be responsible for the payment of all
costs and expenses of re-leasing the space in question (including, without
limitation, all tenant improvement expenses, tenant allowances, leasing
commissions, referral fees and legal fees) and Purchaser alone shall be entitled
to the receipt of all income therefrom. Notwithstanding the foregoing, (i) if
the expenses incurred by Seller during the Interim Period in connection with
such re-leasing of the space (or any portion thereof) previously demised under
an Existing Lease exceeds the gross income received by Seller during the Interim
Period as the result of such re-leasing, then Seller shall receive a credit at
Closing in the amount of such excess and (ii) if the gross income received by
Seller during the Interim Period as the result of such re-leasing of the space
(or any portion thereof) previously demised under an Existing Lease exceeds the
expenses incurred by Seller during the Interim Period in connection with such
re-leasing, then Purchaser shall receive a credit at Closing in the amount of
such excess. Notwithstanding the foregoing, with respect to any Contractual
Right Lease Event that does not result in the termination of an Existing Lease,
at Closing, Seller shall also receive a credit in an amount equal to all tenant
improvement expenses, tenant allowances, leasing commissions, referral fees and
legal fees incurred in connection with such Contractual Right Lease Event.

         (c) If an Involuntary Lease Event occurs with respect to an Existing
Lease during the Interim Period, then during the Interim Period, Seller alone
shall continue to be responsible for the payment of all costs and expenses
attributable to such Existing Lease (as adjusted for the effect of the
Involuntary Lease Event) and Seller alone shall be entitled to the receipt of
all income generated from such Existing Lease (as adjusted for the effect of the
Involuntary Lease Event). If the Involuntary Lease Event results in a Negative
NOI Adjustment, then the Negative NOI Adjustment shall be borne by Seller from
and after the occurrence of the Involuntary Lease Event up to and including the
Apportionment Date and shall be borne by Purchaser from and after the Closing
Date. Following the occurrence of an Involuntary Lease Event during the Interim
Period which results in a tenant vacating the space demised under an Existing
Lease prior to the scheduled expiration thereof, any subsequent re-leasing of
the space (or any portion thereof) previously demised under such Existing Lease
during the Interim Period shall constitute a Purchaser Consent Action, subject
to the provisions of Section 8(a)(i) of this Agreement, it being the intention
of the parties that Purchaser shall ultimately bear all the risks and rewards of
such re-leasing; provided, however, (i) during the Interim Period, subject to
the following provisions of this Section, Seller alone shall be responsible for
the payment of all costs and expenses of re-leasing the space in question
(including, without limitation, all tenant improvement expenses, tenant
allowances, leasing commissions, referral fees and legal fees) and Seller alone
shall be entitled

                                      -21-


to the receipt of all income therefrom and (ii) from and after the Closing Date,
Purchaser alone shall be responsible for the payment of all costs and expenses
of re-leasing the space in question (including, without limitation, all tenant
improvement expenses, tenant allowances, leasing commissions, referral fees and
legal fees) and Purchaser alone shall be entitled to the receipt of all income
therefrom. Notwithstanding the foregoing, (i) if the expenses incurred by Seller
during the Interim Period in connection with such re-leasing of the space (or
any portion thereof) previously demised under an Existing Lease exceeds the
gross income received by Seller during the Interim Period as the result of such
re-leasing, then Seller shall receive a credit at Closing in the amount of such
excess and (ii) if the gross income received by Seller during the Interim Period
as the result of such re-leasing of the space (or any portion thereof)
previously demised under an Existing Lease exceeds the expenses incurred by
Seller during the Interim Period in connection with such re-leasing, then
Purchaser shall receive a credit at Closing in the amount of such excess. The
collection of Receivables and other amounts due from tenants as the result of an
Involuntary Lease Event shall be undertaken in accordance with the provisions of
Section 8A and any sums actually collected as a result thereof shall be applied
in the manner prescribed in such Section.

         (d) If a Voluntary Lease Event occurs with respect to an Existing Lease
during the Interim Period, then, subject to the following provisions of this
Section, (i) during the Interim Period, Seller alone shall continue to be
responsible for the payment of those costs and expenses (including, without
limitation, all tenant improvement expenses, tenant allowances, leasing
commissions, referral fees and legal fees) attributable to such Existing Lease
(as adjusted for the effect of the Voluntary Lease Event), and Seller alone
shall continue to be entitled to the receipt of all income generated from such
Existing Lease (as adjusted for the effect of the Voluntary Lease Event), and
(ii) from and after the Closing Date, Purchaser alone shall be responsible for
the payment of all costs and expenses (including, without limitation, all tenant
improvement expenses, tenant allowances, leasing commissions, referral fees and
legal fees) attributable to such Existing Lease (as adjusted for the effect of
the Voluntary Lease Event) and Purchaser alone shall be entitled to the receipt
of all income from such Existing Lease (as adjusted for the effect of the
Voluntary Lease Event). Notwithstanding the foregoing, (A) if the Pro Forma NOI
which is allocable to an Existing Lease (as adjusted to reflect the actual
Closing Date) is increased as the result of a Voluntary Lease Event, then
Purchaser shall receive a credit at Closing in the amount of such excess and (B)
if the Pro Forma NOI which is allocable to an Existing Lease (as adjusted to
reflect the actual Closing Date) is decreased as the result of a Voluntary Lease
Event, then Seller shall receive a credit at Closing in the amount of such
shortfall. At Closing, Seller shall also receive a credit in an amount (without
duplication of any operating expense item included in the calculation of Pro
Forma NOI pursuant to the immediately preceding sentence) equal to all tenant
improvement expenses, tenant allowances, leasing commissions, referral fees and
legal fees incurred during the Interim Period as the result of any Voluntary
Lease Event with respect to an Existing Lease, including, without limitation,
all such tenant improvement expenses,

                                      -22-


tenant allowances, leasing commissions, referral fees and legal fees incurred in
connection with the re-leasing of any space which is vacated as a result of such
Voluntary Lease Event.

         (e) The provisions of this Section 7 shall survive the Closing for a
period of two (2) years.


         8.  OPERATION OF THE UNIT PRIOR TO CLOSING.

         (a) OPERATION OF THE UNIT DURING THE INTERIM PERIOD. During the Interim
Period, Seller shall have the right and the obligation to continue to operate
and maintain the Unit, subject to the limitations set forth in the Condominium
Declaration. In connection therewith:

                  (i)     From the date hereof until the Closing, Seller shall
         not take, or allow any property manager retained by it to take, any
         Purchaser Consent Action, without the prior written consent of the
         Purchaser (which consent may be withheld in Purchaser's sole and
         absolute discretion). With respect to any proposed Purchaser Consent
         Action to be submitted to Purchaser for its consent pursuant to the
         preceding sentence, Purchaser shall consent or deny its consent, within
         five (5) business days following receipt by Purchaser of Seller's
         notice requesting Purchaser's consent to the proposed action and
         providing Purchaser with all background information necessary for
         Purchaser to make its decision. Failure to respond within such five (5)
         business day period shall be deemed to be an approval of the Purchaser
         Consent Action in question. It is understood that a non-discretionary
         lease renewal, expansion, surrender of space, sublease or assignment
         right or other similar right expressly set forth in an Existing Lease
         in favor of a tenant shall not be deemed to be a Purchaser Consent
         Action to the extent that the specific terms therefor are embodied in
         the lease in question and are non-subjective in nature. For example, if
         a renewal has been granted in favor of a tenant for a specific term and
         at a specified fixed dollar rent per square foot, such renewal will not
         be a Purchaser Consent Action. On the other hand, if a renewal has been
         granted to a tenant for a specific term and at a fair market rent to be
         mutually agreed upon by the Seller and tenant, the ability of Seller to
         agree upon a fair market rent shall be a Purchaser Consent Action. In
         addition to the foregoing, Seller shall not take, or allow any property
         manager retained by it to take, any actions contained in clause (i) of
         the definition of Excluded Decisions to the extent such action relates
         to the granting or withholding of a consent right with respect to a
         material matter under any Lease or involves the incurrence of a
         material expenditure, obligation or other liability without first
         providing written notice to Purchaser of its intention to do so, and
         the reasons therefor; provided, however, Seller agrees that, to the
         extent requested in writing by Purchaser within three (3) business days
         after receipt by Purchaser of such

                                      -23-


         notice from Seller, Seller shall refrain from taking any such
         contemplated action, provided that Purchaser agrees to indemnify and
         hold Seller harmless from any loss, cost, damage, claim, liability and
         expense (including, without limitation, reasonable attorneys' fees)
         which Seller shall incur resulting from Seller's failure to take any
         such action.

                  (ii)    Intentionally Omitted

                  (iii)   From the date hereof until the Closing, Seller shall
         not take, or omit to take, any action that would have the effect of
         violating in any material respect any of the representations,
         warranties, covenants and agreements of Seller contained in this
         Agreement. Nothing contained in the foregoing sentence shall be
         construed to preclude Seller from taking, or omitting to take, any
         action that is (x) approved in writing by Purchaser (whether as a
         Purchaser Consent Action or otherwise), (y) required to be taken
         pursuant to this Agreement, or (z) pertaining to the Common Elements
         and approved by the Board of Managers. From the date hereof until the
         Closing, Purchaser shall not take, or omit to take, any action that
         would have the effect of violating in any material respect any of the
         representations, warranties, covenants and agreements of Purchaser
         contained in this Agreement.

                  (iv)    From the date hereof until the Closing, Seller shall
         not sell, assign, or convey any right, title or interest whatsoever in
         or to the Unit, or create or permit to exist any lien, security
         interest, easement, encumbrance, charge or condition affecting the Unit
         (other than a Permitted Encumbrance), without the prior consent of
         Purchaser except to the extent relating to (w) actions reasonably
         necessary or desirable in connection with the marketing and sale of the
         Unit to the Purchaser pursuant to the Exchange Agreement contemplated
         by this Agreement, (x) leasing of the Unit or portions thereof as
         permitted in accordance with this Agreement, (y) items affecting the
         Common Elements approved by the Board of Managers or (z) items approved
         in writing by Purchaser (whether as a Purchaser Consent Action or
         otherwise).

                  (v)     From the date hereof until the Closing, Seller shall
         promptly deliver to Purchaser copies of (a) written default notices,
         notices of lawsuits and notices of violations affecting the Unit that
         are sent or actually received by Seller, (b) without duplication of
         anything contained in the preceding clause (a), any notice received
         from the City of New York, any taxing authority and any other
         municipal, governmental or quasi-governmental entity or agency
         pertaining to the Unit, and any notices received from the Grand Central
         Partnership and (c) monthly operating statements for the Unit.

                  (vi)    From the date hereof until the Closing, Seller shall
         maintain in full force and effect business interruption insurance to
         cover loss of rental income in an amount not less than twelve (12)
         months' projected gross income of the Unit and the other

                                      -24-


         insurance polices described in Schedule 11(a)(xv) attached hereto and
         shall otherwise continue to operate the Unit in substantially the same
         manner as it operated the Unit prior to the execution and delivery of
         this Agreement and otherwise in a first-class manner, and shall pay all
         operating expenses and real estate taxes which are the responsibility
         of the owner of the Unit during the Interim Period.

                  (vii)   From the date hereof until the Closing, Seller and
         Purchaser shall convene (by phone or in person) not less frequently
         than once per calendar week to discuss any and all matters relating to
         the operation, management, leasing, maintenance or repair of the Unit.
         Each party hereto shall exercise its rights and obligations under this
         Agreement in a manner which is consistent with the rights and
         obligations of the parties under the Condominium Declaration.

                  (viii)  From the date hereof until the Closing, Seller shall
         file with the New York City Department of Finance ("NYCDF"), at such
         times and in such manner as may be required under New York City
         Administrative Codess.11-256 et. seq., the Industrial and Commercial
         Incentive Program ("ICIP"), a Certificate of Continuing Use and such
         other documentation as the NYCDF may reasonably require.

                  (ix)    From the date hereof until the Closing, Seller shall
         deliver to Purchaser, promptly after the execution and delivery thereof
         by all parties thereto, copies of all agreements pertaining to Lease
         Events.


         8A. TREATMENT OF CERTAIN MATTERS.

         (a) COLLECTION OF RECEIVABLES, CURRENT SUMS AND ARREARAGES.

         (1) Seller shall, until the Closing Date, undertake its customary
collection efforts to collect all Receivables and other amounts due from tenants
(subject to the limitations provided in Section 8A(a)(5) below), which may
include the submission of monthly invoices and follow-up invoices, and may (but
need not) include the commencement or continuation of litigation or other
proceedings, it being agreed that any monies received by Seller as a result of
such collection efforts (net of the reasonable costs allocable to the collection
of the same) attributable to the period prior to the Closing Date shall (except
as specifically provided to the contrary in Sections 7(b), (c) and (d)) belong
to Seller and shall not constitute a credit against the Purchase Price.

         (2) Purchaser shall, from and after the Closing Date, undertake its
customary collection efforts on behalf of Seller to collect all Receivables for
a period of six (6) months after the Closing Date (subject to the limitations
provided in Section 8A(a)(5) below), which may include the submission of monthly
invoices and follow-up invoices, and may (but need

                                      -25-


not) include the commencement or continuation of litigation or other
proceedings, it being agreed that in such cases any monies received by Purchaser
from and after the Closing Date from any party liable for any portion of the
Receivables to be collected by Purchaser shall be applied in the following
order:

         FIRST            to the payment pro-rata (on the basis of costs
                          incurred) of all reasonable costs of collection,
                          including reimbursement to Seller or Purchaser of any
                          legal fees or collection costs reasonably incurred by
                          either of them and allocable to the collection of such
                          Receivables pursuant to the foregoing provisions of
                          this Section,

         SECOND           to the payment of monies owed to Seller and Purchaser
                          for the billing period in progress on the Closing
                          Date,

         THIRD            to Purchaser for sums owed to Purchaser relating to
                          billing periods after the billing period in progress
                          as of the Closing Date, and

         LAST             to the balance of any Receivables.

         (3) If within six (6) months following the Closing Date, any of the
Receivables to be collected by Purchaser that are payable to Seller in
accordance with the terms of this Section 8A(a) have not been collected and
remitted to Seller, or Purchaser has not commenced litigation to collect such
Receivables, then Seller may undertake its own efforts to collect such
Receivables, including the commencement of litigation and other proceedings (but
Seller shall not seek to evict any tenant or terminate any Lease), and in which
event all sums collected by Seller as a result of such litigation (after payment
of all costs and expenses) shall be applied in full satisfaction of the subject
Receivables, it being agreed that Seller shall refrain from taking any such
efforts during the six (6) month period following the Closing Date.

         (4) With respect to any pending litigation or other proceedings to
collect any Receivables from tenants in occupancy on the Closing Date, Purchaser
shall have the option on the Closing Date of either (i) continuing such
litigation or proceedings (the costs of which shall be equitably apportioned
between Seller and Purchaser, based upon the amounts ultimately paid to each,
and reimbursed out of the first monies collected, if any) and Purchaser shall be
substituted as the plaintiff, if necessary, or (ii) not continuing the
litigation, whereupon Seller may continue such litigation in its own name and at
its sole cost and expense, provided that such litigation shall not result in the
eviction of the tenant or the termination of its Lease without Purchaser's
consent, and in which event all sums collected by Seller as a result of such
litigation (after payment of all actual out-of-pocket costs and expenses) shall
be applied in full satisfaction of the subject Receivables.

                                      -26-


         (5) Notwithstanding anything hereinabove provided, (i) during the
Interim Period, Seller shall not settle or compromise any claims against any
tenants of the Unit without Purchaser's prior written approval, it being agreed
that the settlement or compromise of any such claims shall constitute a
Purchaser Consent Action, subject to the provisions of Section 8(a) of this
Agreement, (ii) after the Closing, neither Seller nor Purchaser shall settle or
compromise any claims against any tenants of the Unit which include both
Receivables payable to Seller and amounts payable to Purchaser without the other
party's prior written approval, which approval shall not be unreasonably
withheld or delayed and (iii) to the extent the Receivables that are subject to
collection are the Receivables identified in clause (ii) of the definition of
Receivables, the rights and obligations of Seller and Purchaser shall be
qualified to provide that such parties shall use commercially reasonable good
faith efforts to cause the Board of Managers to comply with the relevant
provisions of Section 8A of this Agreement. Notwithstanding the foregoing,
Purchaser shall have the right to settle or compromise a claim against a tenant
of the Unit without the consent of (but after prior notice to) Seller to the
extent such claim relates solely to the period of time after the Closing and
provided that the settlement or compromise of such claim does not have a
material adverse effect on any claim that Seller may have against such tenant.

         (6) Notwithstanding anything to the contrary hereinabove provided,
Seller shall retain the sole right to collect (in such manner as it shall deem
appropriate) those Receivables, if any, listed on Schedule 8A(a)(6) attached
hereto as well as Receivables with respect to any tenant whose lease has
terminated prior to the Apportionment Date and has vacated its demised premises,
it being further agreed that Purchaser shall not be required to undertake any
collection efforts with respect to such Receivables.

         (7) Any monies received by Seller or Purchaser that are to be applied
to sums owed to the other party hereto hereunder (whether on account of
Receivables, current sums due, arrearages or otherwise) shall be held in trust
by Seller or Purchaser, as the case may be, for the benefit of the other party
and remitted to such other party promptly after receipt. Seller and Purchaser
shall reasonably cooperate with each other in the collection of Receivables and,
provided there is no liability or material expense associated therewith, shall
execute any documents reasonably requested by the other to collect such
Receivables.

         (b) PROTEST PROCEEDINGS.

                  (1) GENERALLY. As of the date of this Agreement, Seller may
         have engaged various law firms or consultants to protest the valuation
         of the Unit ("Protest Proceedings") for the purpose of protesting the
         amount of ad valorem taxes for certain tax fiscal periods, some of
         which taxes may have been paid by Seller and some of which taxes either
         are not yet due and payable or have not been paid. With respect to the
         tax year in which the Closing occurs, and all prior tax years, Seller
         is hereby authorized (during the Interim Period) to continue any
         Protest Proceeding for the Unit,

                                      -27-


         it being acknowledged that the trial or settlement of any such Protest
         Proceeding during the Interim Period shall constitute a Purchaser
         Consent Action, subject to the provisions of Section 8(a) of this
         Agreement. All net tax refunds and credits attributable to any tax year
         prior to the tax year in which the Closing occurs shall belong to and
         be the property of Seller, subject to the rights of tenants under their
         respective Leases. All net tax refunds and credits attributable to any
         tax year subsequent to the tax year in which the Closing occurs shall
         belong to and be the property of Purchaser, subject to the rights of
         tenants under their respective Leases. All net tax refunds and credits
         attributable to any tax year not described in the preceding two (2)
         sentences shall be divided between Seller and Purchaser in accordance
         with the apportionment of taxes set forth in Section 8A(b)(2) below.
         Seller and Purchaser agree to cooperate with one another in connection
         with the prosecution of any such proceedings and to take all reasonable
         steps, whether before or after the Closing Date, as may be reasonably
         necessary to carry out the intention of the foregoing, including,
         without limitation, to the extent in a party's possession, the delivery
         to the party pursuing the appeal of any relevant books and records,
         including receipted tax bills and canceled checks used in payment of
         such taxes, and, provided that there is no liability or material
         expense to the party delivering such materials in doing so, the
         execution of any and all consents or other documents, and the
         undertaking of any act necessary for the collection of such refund. The
         parties agree to keep one another apprised of all such proceedings, to
         provide one another (except to the extent that the attorney-client
         privilege would be violated) with copies of all relevant books, records
         and documentation relating to any such proceeding, and with respect to
         any course of action which the pursuing party could reasonably expect
         to have a material impact on any proceeding or on the outcome of any
         proceeding, such party agrees to consult with the other party and to
         obtain such party's consent (which consent shall not be unreasonably
         withheld or delayed) before proceeding with any such action.
         Notwithstanding the foregoing limitation, Seller agrees that neither
         Seller nor its representatives will withhold, because of the
         attorney-client privilege or work product immunity, from Purchaser or
         its representatives any relevant information received by Seller or its
         representatives from, or delivered by Seller or its representatives to,
         the New York City taxing authorities. If either party hereto shall
         receive any refund payments contemplated by this subsection 8A(b) which
         are properly payable to the other party, such payments shall be held in
         trust by such party, for the benefit of the other, and remitted to such
         other party promptly after receipt.

                  (2) The Net Refund (as hereinafter defined) payable by virtue
         of a favorable determination resulting from any Protest Proceeding with
         respect to the tax fiscal period in progress on the Apportionment Date
         shall be prorated between Seller and Purchaser on a per diem basis,
         with Seller being entitled to receive the portion thereof allocated to
         the portion of such tax fiscal period up to and including the
         Apportionment Date.

                                      -28-


         The term "Net Refund" as used herein shall mean the portion of any
         refund (including, without limitation, any interest payable thereon)
         that is payable by virtue of a favorable determination resulting from
         any Protest Proceeding and that is entitled to be retained by the party
         so entitled thereto pursuant to the foregoing provisions after (i)
         payment or reimbursement (on a pro-rata basis) of all fees and
         out-of-pocket expenses including, without limitation, counsel fees and
         disbursements and consultant's fees incurred in obtaining such refund,
         the allocation of such expenses to be based upon the total refund
         obtained in such proceeding and in any other proceeding simultaneously
         involved in the trial or settlement and (ii) the refunding by such
         party of the portion of any such refund, if any, owing to tenants under
         the Leases on account of such refund attributable to the applicable
         periods covered thereby.

                  (3) Intentionally Omitted.

                  (4) CONTROL OF PROTEST PROCEEDINGS, SETTLEMENT AND COMPROMISE.
         In connection with any Protest Proceeding for the tax fiscal period in
         progress on the Closing Date, at Purchaser's request Seller shall, if
         possible, cause Purchaser to be substituted for Seller in such Protest
         Proceeding and any other pending Protest Proceedings for tax fiscal
         periods commencing prior to the tax fiscal period in progress on the
         Closing Date, or if not possible, Seller shall permit Purchaser to
         control the conduct of all such Protest Proceedings. Notwithstanding
         anything hereinabove provided, (i) during the Interim Period, Seller
         shall not settle or compromise any Protest Proceedings in which taxes
         for any tax fiscal period in progress on or prior to the Closing are
         being adjudicated without Purchaser's prior written approval, it being
         agreed that the settlement or compromise of any such Protest
         Proceedings shall constitute a Purchaser Consent Action, subject to the
         provisions of Section 8(a) of this Agreement and (ii) after the
         Closing, neither Seller nor Purchaser shall settle or compromise any
         Protest Proceedings pending on the Closing Date in which taxes for any
         tax fiscal period in progress on or prior to the Closing Date are being
         adjudicated without the other party's prior written approval, which
         approval shall not be unreasonably withheld or delayed. Seller and
         Purchaser shall otherwise cooperate with each other in all reasonable
         respects with respect to all Protest Proceedings. From and after the
         Closing Date, Purchaser shall have the right, subject to the above
         provisions of this Section 8A(b)(4) and subject to the terms and
         provisions of the Condominium Declaration, to withdraw, compromise,
         settle, try or otherwise deal with such petitions or applications with
         respect to the Unit as Purchaser in the exercise of its sole judgment
         shall deem appropriate.

         (c) SURVIVAL. The provisions of this Section 8A shall survive the
Closing for a period without expiration.

                                      -29-


         9.  RECORDING CHARGES, TRANSFER AND CONVEYANCE TAXES; WITHHOLDING;
             INTERNAL REVENUE SERVICE REPORTING REQUIREMENTS.

         (a) RECORDING CHARGES; TAXES GENERALLY. Purchaser shall pay all
recording charges and fees and sales taxes, if any, imposed in connection with
the conveyance of the Unit to Purchaser. All real estate transfer and conveyance
taxes paid or payable in connection with the transactions herein contemplated
shall be paid by Seller and/or Purchaser in the manner hereinafter provided in
this Section 9.

         (b) TRANSFER TAXES.

                  (i)     Seller shall pay the New York State Real Estate
         Transfer Tax (the "State Transfer Tax") in accordance with Article 31
         of the Tax Law of the State of New York, and the New York City Real
         Property Transfer Tax (the "City Transfer Tax") imposed by Chapter 21,
         Title 11 of the Administrative Code of the City of New York, in
         connection with the conveyance of the Unit to Purchaser in accordance
         with the provisions of this Agreement. Seller shall defend, indemnify
         and hold harmless Purchaser from and against any loss, cost, damage,
         claim, liability and expense (including, without limitation, reasonable
         attorneys' fees) that may be suffered or incurred by Purchaser by
         reason of the failure of Seller to pay the State Transfer Tax and the
         City Transfer Tax, if applicable, as pertains to this transaction, as
         provided in this Section 9(b), it being understood that the foregoing
         indemnification shall not apply to any tax liability resulting from an
         actual disposition of the Unit by Purchaser following its acquisition
         thereof at the Closing.

                  (ii)    In addition to the foregoing, Seller shall defend,
         indemnify and hold harmless Purchaser from and against any additional
         State Transfer Tax and/or City Transfer Tax (inclusive of interest and
         penalties thereon) that may be suffered or incurred by Purchaser by
         reason of the assertion by any taxing authority having jurisdiction
         over the subject matter thereof that (i) the conveyance of the Unit to
         DLIP's assignee in the manner contemplated by this Agreement
         constitutes a "double transfer" or (ii) the purchase price for the Unit
         under this Agreement should have been in excess of $185,000,000.

                  (iii)   Seller and Purchaser shall each execute and/or swear
         to the returns or statements required in connection with the State
         Transfer Tax and the City Transfer Tax, and any other taxes referred to
         in this Section 9(b) or otherwise applicable to the transactions
         contemplated by this Agreement, and shall deliver same, together with
         the check or checks of Seller and/or Purchaser, as the case may be, in
         payment thereof which are required of such party, to the Title Insurer
         on the Closing Date. All such tax payments shall be made by certified
         or bank check payable directly to the order of the

                                      -30-


         appropriate governmental officer, or in such manner as the Title
         Insurer shall reasonably require and accept.

                  (iv)    In the event that any taxing authority shall commence
         or file, or threaten to commence or file, any lawsuit or proceeding,
         which pending or threatened lawsuit or proceeding may result in any
         loss, liability or damage subject to indemnification under Section
         9(b)(ii) above (collectively, a "Transfer Tax Proceeding"), then
         Purchaser will give prompt written notice of such Transfer Tax
         Proceeding to Seller (a "Notice of Transfer Tax Proceeding"), and
         Seller shall have the right, upon written notice to Purchaser, within
         thirty (30) days of receipt of such Notice of Transfer Tax Proceeding,
         to undertake the defense thereof by tax representatives chosen by
         Seller and approved by Purchaser (which approval shall not be
         unreasonably withheld or delayed). If Seller gives written notice that
         Seller accepts responsibility to contest, and/or defend Purchaser
         against, such Transfer Tax Proceeding within thirty (30) days of
         receipt of a Notice of Transfer Tax Proceeding, (i) Seller shall be
         obligated to diligently contest, and/or defend Purchaser against, such
         Transfer Tax Proceeding at Seller's own expense, and to keep Purchaser
         apprised of the current status of such Transfer Tax Proceeding at all
         times (except to the extent the attorney-client privilege would be
         violated), (ii) Seller will not be liable to Purchaser for separate
         legal or other expenses incurred by Purchaser in connection with such
         contest and/or defense, (iii) Purchaser shall cooperate in all
         reasonable respects with Seller in the contest and/or defense of such
         Transfer Tax Proceeding, and shall promptly send to Seller copies of
         any documents received by Purchaser which relate to such Transfer Tax
         Proceeding and (iv) Purchaser shall have the right, but not the
         obligation to retain separate tax representatives at Purchaser's own
         cost and expense and (provided the attorney-client privilege would not
         be violated) to attend meetings (including, without limitation, with
         the taxing authority and the tax representatives retained by Seller)
         and to otherwise monitor the Transfer Tax Proceeding. Notwithstanding
         the foregoing limitation, Seller agrees that neither Seller nor its tax
         representatives will withhold, because of the attorney-client privilege
         or work product immunity, from Purchaser or its tax representatives any
         relevant information received by Seller or its tax representatives
         from, or delivered by Seller or its tax representatives to, the New
         York City and New York State taxing authorities. If Seller, within
         thirty (30) days after receipt of any Notice of Transfer Tax
         Proceeding, fails to elect in writing to contest, and/or defend
         Purchaser against, any such Transfer Tax Proceeding, or if Seller
         defaults in its obligation to diligently contest, and/or defend
         Purchaser against, any such Transfer Tax Proceeding at any time
         subsequent to Seller's acceptance of such obligation, and if such
         failure or such default shall continue for five (5) business days after
         notice by Purchaser to Seller thereof, Purchaser shall thereafter have
         the right, but not the obligation, to undertake the defense, compromise
         or settlement of such Transfer Tax Proceeding on behalf of Seller, it
         being understood that Seller shall thereafter reimburse Purchaser, upon
         demand, for all costs, expenses and

                                      -31-


         liabilities incurred by Purchaser in connection with such defense,
         compromise or settlement, including, without limitation, reasonable
         attorneys' fees. If and to the extent any liability hereunder has been
         insured through contractual indemnity insurance, the amount available
         for recovery by Purchaser hereunder shall be reduced by such amounts as
         are recovered and received by Purchaser through such insurance.

fifteen (15) business days' prior notice of the date on which the Closing is to

violations of laws or governmental ordinances, rules, regulations, orders or
requirements (collectively, "Laws") issued by any governmental authority having
jurisdiction over the Unit and that relate to the period of time prior to the
Closing Date shall be the responsibility of Seller irrespective of whether or
not notices of such violations are issued or noted prior to the Closing Date and
irrespective of whether or not actually received by Seller prior to the Closing
Date. Any such notices of violations that are actually received by Seller prior
to the Closing Date shall be removed or complied with by Seller on or before the
Closing Date. Notwithstanding the foregoing provisions of this Section 14(a) to
the contrary, if such removal or compliance has not been completed on or before
the Closing Date, Seller may elect to either (i) deliver an undertaking to
Purchaser at Closing to diligently cause such violations to be removed

as an adjustment to the Purchase Price payable to Seller pursuant to Section 3
of this Agreement) an amount sufficient, in the reasonable judgment of Seller
and Purchaser, to pay for the performance of the work and provision of the
materials necessary to effect or complete such removal or compliance, and upon
Seller making such payment or giving such credit, Purchaser shall be required to
accept title to the Unit subject to such notices of violations and (except for
notices of violations of Laws that are issued by any governmental authority
having jurisdiction over the Unit and that relate to the period of time prior to
the Closing Date but are not actually received by Seller prior to the Closing
Date) Seller shall have no further obligation to remove or comply with such
notices of violations. Purchaser shall deliver to Seller copies of any notices
of violations of Laws that are issued by any governmental authority having
jurisdiction over the Unit that are received by Purchaser after the Closing Date
but that relate to the period of time prior to the Closing Date and Seller
shall, subject to the provisions of this Section 14, diligently cause such
notices to be removed or complied with.

         (b) Notwithstanding anything in this Section 14 to the contrary, Seller
shall not be obligated to remove or comply with any notices of violations to the
extent such notices relate to any of the following violations:

         (i)  Any violation which is the obligation of any tenant or other
         occupant under a Lease in effect at the Closing (other than Seller) to
         remedy, it being understood that, until the Closing Date, Seller shall
         use commercially reasonable good faith efforts to cause such tenant or
         other occupant to remedy the same; and

         (ii) Any violations relating to the sidewalks abutting Citigroup Center
         or relating to the Common Elements (except to the extent that such
         violations relate to exterior signage or matters within the reasonable
         control of Seller provided that Purchaser cooperates with Seller in
         connection therewith to the extent reasonably requested by Seller), it
         being understood that, until the Closing Date, Seller and Purchaser
         shall cooperate with each other and shall use their commercially
         reasonable good faith efforts to cause the Board of Managers to remedy
         the same.

Purchaser shall accept title to the Unit subject to all violations not required
to be removed pursuant to this Section 14.

         (c) The provisions of this Section 14 shall survive the Closing for a
period of two (2) years.

         (a) If, between the date hereof and the Closing, there shall occur a
fire or other casualty resulting in the damage or destruction of fifty percent
(50%) or more of the floor space of Citigroup Center (a "Major Casualty"),
Purchaser shall have the right, exercisable by giving written notice to Seller
within ten (10) days after receiving written notice of such fire or other
casualty, to terminate this Agreement, in which case neither party shall have
any further rights or obligations hereunder except such obligations which
expressly survive the termination of this Agreement. If, between the date hereof
and the Closing, there shall occur a fire or other casualty affecting all or any
part of the Unit or any other portion of Citigroup Center other than a Major
Casualty, neither Seller nor Purchaser shall (except as specifically provided to
the contrary in subsection (b) below) have the right to terminate this
Agreement, and in such event, or in the event of a Major Casualty as to which
Purchaser shall not exercise the termination option contained in the first
sentence of this subsection, then (i) the parties shall proceed to Closing
without reduction of or offset against any amounts payable hereunder or any
other claim against the other, (ii) at the Closing, Seller shall (x) pay over to
Purchaser the proceeds of any insurance collected by Seller less the amount of
all costs incurred by Seller in connection with the repair of such damage or
destruction, all of which costs incurred by Seller shall be a Purchaser Consent
Action and (y) assign and transfer to Purchaser, subject to the terms of the
Condominium Declaration, all right, title and interest of Seller in and to any
uncollected insurance proceeds which Seller may be entitled to receive from such
damage or destruction and (iii) the parties hereto shall cooperate in all
reasonable respects in order to

                                      -48-


effectuate such intent. The provisions of this Section 16 shall survive the
Closing for a period without expiration.

         (b) In addition to and supplementing the provisions of subsection (a)
above, the following provisions of this subsection shall be applicable if a fire
or other casualty resulting in the damage or destruction of the Unit shall occur
between the date hereof and the Closing (whether or not such fire or other
casualty constitutes a Major Casualty):

                  (i)     If more than 44.4% of the Citibank Leased Premises
         (i.e., 195,000 rentable square feet) is damaged or destroyed and if the
         estimated period (the "Estimated Repair Period") for the completion of
         the required repair and restoration of the Unit, as determined in
         accordance with the provisions of subsection (b)(vi) below, exceeds 720
         days from the Casualty Repair Period Commencement Date (as hereinafter
         defined), Seller shall have the absolute and unconditional right at its
         option to terminate this Agreement by notice given to Purchaser not
         later than fifteen (15) business days after the Estimated Repair Period
         is so determined. If the damage or destruction of the Unit occurs prior
         to the Breakpoint Date (as hereinafter defined), the "Casualty Repair
         Period Commencement Date" shall, for the purposes of this subsection
         (b), be the earlier to occur of the Breakpoint Date or the Closing
         Date, and if the damage or destruction shall occur on or subsequent to
         the Breakpoint Date, the "Casualty Repair Period Commencement Date"
         shall, for the purposes of this subsection (b), be the date upon which
         the damage or destruction shall have occurred. The term "Breakpoint
         Date", as used in this subsection (b), shall mean July __, 2001.

                  (ii)    If more than 44.4% of the Citibank Leased Premises
         (i.e., 195,000 rentable square feet) is damaged or destroyed and if the
         Estimated Repair Period, as determined in accordance with the
         provisions of this subsection hereinafter set forth, exceeds 720 days
         from the Casualty Repair Period Commencement Date, but Seller does not
         elect to terminate this Agreement pursuant to subsection (b)(i) above,
         and if this Agreement is not otherwise terminated by Purchaser in
         accordance with the provisions of subsection (a) above, this Agreement
         shall remain in full force and effect, and Seller shall (except as
         otherwise expressly provided to the contrary in subsection (v) below)
         be absolutely and unconditionally obligated to execute and deliver the
         Citibank Lease on the Closing Date in accordance with the provisions of
         this Agreement irrespective of whether the required repair and
         restoration of the Unit have been completed as of the Closing Date.

                  (iii)   If Seller does not have the right to terminate this
         Agreement because less than 44.4% (i.e., 195,000 rentable square feet)
         of the Citibank Leased Premises is damaged or destroyed, or if more
         than 44.4% (i.e., 195,000 rentable square feet) of the Citibank Leased
         Premises is damaged or destroyed, but Seller does not have the right to
         terminate this Agreement because the Estimated Repair Period is equal
         to or

                                      -49-


         less than 720 days, and if this Agreement is not otherwise terminated
         by Purchaser in accordance with the provisions of subsection (a) above,
         this Agreement shall remain in full force and effect, and Seller shall
         (except as otherwise expressly provided to the contrary in subsection
         (v) below) be absolutely and unconditionally obligated to execute and
         deliver the Citibank Lease on the Closing Date in accordance with the
         provisions of this Agreement irrespective of whether the required
         repair and restoration of the Unit have been completed as of the
         Closing Date.

                  (iv)    If the Unit and/or Citigroup Center is damaged or
         destroyed by fire or other casualty between the date hereof and the
         Closing, and if this Agreement is not terminated in accordance with the
         provisions of subsection (a) or subsection (b) set forth above, and if
         the required repair and restoration of the Unit have not been completed
         as of the Closing Date, the rights and obligation of Citibank under the
         Citibank Lease shall, without further act or instrument, be deemed
         modified and qualified as follows until such time as the required
         repairs and restoration of the Unit shall have been completed in
         accordance with the provisions of this Section hereinafter set forth:

                           (1) Notwithstanding anything to the contrary set
                  forth in the Citibank Lease, including, without limitation,
                  Section IX of the Citibank Lease, neither the Base Rent nor
                  the Additional Rent (as defined in the Citibank Lease) shall
                  be abated with respect to the portion of the Unit so damaged
                  or destroyed, it being the intent that Seller shall be
                  obligated to pay Base Rent and Additional Rent with respect to
                  all of the Unit, including without limitation, the portions
                  thereof which have been so damaged or destroyed.

                           (2) Notwithstanding anything to the contrary
                  contained in the Citibank Lease, Seller shall not have any
                  further right to terminate the Citibank Lease as a result of
                  the occurrence of any such fire or other casualty prior to the
                  date of the Closing.

                  (v)     Notwithstanding anything to the contrary set forth
         above in this Section 16 or elsewhere in this Agreement, if the Unit
         and/or Citigroup Center is damaged or destroyed by fire or other
         casualty prior to the Closing, and if this Agreement is not terminated
         in accordance with the provisions of subsection (a) or this subsection
         (b) above, and if the required repair and restoration of the Unit have
         not been completed as of the date upon which the Closing has been
         scheduled by Purchaser in accordance with the provisions of Section 13
         of this Agreement, Seller shall (except as specifically provided to the
         contrary in the next sentence of this subsection) have the absolute and
         unconditional right at its option, by written notice given to Purchaser
         on or prior to the date such Closing has been scheduled to occur, to
         postpone the Closing until the earlier to occur of the date upon which
         the required repair and restoration

                                      -50-


         shall have been completed in accordance with the standards set forth in
         subsection (iv)(2) above or April 1, 2002. If three floors or less of
         the Unit shall have been damaged or destroyed by fire or other
         casualty, Seller shall not have the right pursuant to the preceding
         sentence of this subsection to postpone a Closing which has been
         scheduled by Purchaser in accordance with the provisions of Section 13
         of this Agreement. If such repair and restoration have not been
         completed by April 1, 2002, the Closing shall occur on April 1, 2002
         (unless otherwise agreed to the contrary by Seller and Purchaser) in
         which case the provisions of subsections (iv)(1) and (iv)(2) above, as
         applicable, shall be in effect.

                  (vi)    As promptly as possible after the occurrence of any
         damage or destruction to the Unit, Seller and Purchaser shall take such
         steps as may be commercially reasonable to determine the period of time
         that will be necessary to effect the required repair and restoration to
         the Unit, including, without limitation, the hiring at the shared cost
         and expense of Seller and Purchaser of such engineers, architects and
         other consultants as may be reasonably necessary to make such
         determination. Seller and Purchaser shall take all steps as may be
         commercially reasonable to promptly commence and to diligently pursue
         to completion the required repairs and restoration of the Unit
         (including, without limitation, by causing the Board of Managers to
         take such actions and/or prosecute such insurance claims as may be
         reasonably necessary or desirable in connection therewith) both before
         and after the Closing Date, and shall cooperate with one another in all
         reasonable respects in connection therewith. If the Unit and/or
         Citigroup Center shall be damaged or destroyed by fire or other
         casualty prior to the Closing, and if this Agreement is not terminated
         in accordance with the provisions of subsection (a) or this subsection
         (b) above, Seller and Purchaser shall cause the Board of Managers to
         retain Seller, as its agent, to effect all repairs and restoration to
         Citigroup Center and/or the Unit which are required to be effected by
         the Board of Managers on behalf of the unit owners in Citigroup Center
         in accordance with the provisions of the Condominium Declaration. The
         retention of Seller as such agent, and Seller's agreement to act as
         such agent and to effect the completion of such repairs and
         restoration, shall be evidenced by an agreement in writing in form and
         substance reasonably satisfactory to Seller and Purchaser to be entered
         into among Seller, Purchaser and the Board of Managers, which agreement
         shall remain in full force and effect until all the required repairs
         and restoration shall have been completed and irrespective of whether
         the required repairs and restoration are completed before or after the
         Closing. Seller shall have the right under the terms of such retention
         agreement to take all steps as may be reasonably necessary to effect
         the expeditious completion of the required repairs and restoration,
         including without limitation, the hiring at the shared pro rata cost
         and expense of Seller and Purchaser (as determined on the basis of
         their respective ownership interest in Citigroup Center as of the date
         of this Agreement) of such architects, engineers, consultants,
         contractors, materialmen and subcontracts as may be necessary to effect
         the completion of the required repairs

                                      -51-


         and restoration. Seller shall be obligated at all times to act in good
         faith and in a commercially reasonable fashion in effecting the
         required repairs and restoration in a timely and expeditious manner,
         including without limitation, effecting the required repairs and
         restoration at commercially reasonable and competitive prices taking
         into account the scope and severity of the damage or destruction and
         the necessity to complete required repairs and restoration as quickly
         and expeditiously as possible. In this regard, Seller agrees that
         construction contracts will be let on an arms-length basis after
         competitive bidding, it being agreed, however, that Seller shall have
         the right in its reasonable and good faith discretion to select the
         contractors which in its opinion are most qualified to complete the
         required repairs and restoration notwithstanding the fact that such
         contractors may have submitted bids in excess of those submitted by
         other contractors. Seller shall keep Purchaser and the Board of
         Managers up to date and fully informed on the status, timing and cost
         of effecting the required repairs and restoration, and shall upon
         request of Purchaser or the Board of Managers provided such information
         with respect thereto as may be reasonably requested from time to time
         by the Purchaser or the Board of Managers. The Citigroup Center shall
         be repaired and restored to a condition substantially conforming to the
         plans and specifications therefor in effect immediately prior to such
         fire or other casualty (except for commercially reasonable deviations
         therefrom required for upgrades to the Citigroup Center, as shall be
         determined by Seller and Purchaser, each in the exercise of its
         reasonable discretion, or as required to conform to applicable laws)
         or, to the extent that Seller and Purchaser shall both agree, in
         accordance with new plans and specifications, which plans and
         specifications may be prepared by or at the request of Seller, PROVIDED
         THAT the same are prepared in accordance with the requirements of
         Paragraph 2.1 of Exhibit O of the Citibank Lease as to the submission
         of plans and specifications, and FURTHER PROVIDED THAT such plans and
         specifications shall be subject to the approval of Purchaser, which
         approval shall not be unreasonably withheld or delayed. Insurance
         proceeds which are available to cover the costs of such repairs and
         restoration shall be paid over to Seller as collected from the
         applicable insurance companies, which proceeds shall be used by Seller
         solely to cover the payment of actual costs and expenses incurred in
         connection with the making of the required repairs and restoration, it
         being agreed that (1) Seller and Purchaser shall share on a pro rata
         basis (as determined in accordance with their respective ownership
         interests in Citigroup Center as of the date of this Agreement) all
         costs and expenses which are incurred in connection with the making of
         such required repairs and restoration to the extent that the available
         insurance proceeds are not sufficient to cover the cost thereof, and
         (2) the remaining balance, if any, of such insurance proceeds after the
         payment of all costs and expenses incurred in connection with the
         making of the required repairs and restoration shall be shared by
         Seller and Purchaser on a pro rata basis (as determined in accordance
         with their respective ownership interests in Citigroup Center as of the
         date of this Agreement). Notwithstanding anything to the contrary
         herein above set forth in this subsection, it is agreed that (x)
         insurance proceeds which are

                                      -52-


         paid under insurance policies covering tenant improvements in the space
         currently occupied by Seller shall be allocated and available solely to
         cover the cost of repairing and restoring such tenant improvements, (y)
         to the extent such insurance proceeds are not sufficient to cover the
         cost of repairing and restoring such tenant improvements, all of such
         excess costs shall be covered solely by Seller, and (z) the remaining
         balance, if any, of such insurance proceeds after the payment of all
         costs and expenses incurred in connection with the making of such
         repairs and restoration shall belong solely to Seller. Notwithstanding
         anything to the contrary herein above set forth in this subsection, it
         is agreed that (A) at Purchaser's option, each of the tenants in
         Citigroup Center Office Unit One may be permitted to be responsible for
         the repair and restoration of its tenant improvements, including the
         selection and hiring of contractors, subcontractors and other
         professionals, all in accordance with the terms of its lease, (B)
         insurance proceeds which cover tenant improvements in Citigroup Center
         Office Unit One shall be allocated and available solely to cover the
         cost of repairing and restoring such tenant improvements, (C) to the
         extent such insurance proceeds are not sufficient to cover the cost of
         repairing and restoring such tenant improvements, all of such excess
         costs shall be covered by Purchaser and/or the tenants occupying space
         in Citigroup Center Office Unit One, and (D) the remaining balance, if
         any, of such insurance proceeds after the payment of all costs and
         expenses incurred in connection with the making of such repairs and
         restoration shall belong solely to Purchaser and/or such tenants, as
         applicable. Seller and Purchaser shall cooperate in all reasonable ways
         to effect the timely commencement and completion of all such required
         repairs and restoration.

                  (vii)   The provisions of this subsection (b) shall to the
         full extent applicable, and for so long as the same shall be
         applicable, survive the Closing under this Agreement. From and after
         the Closing Date, the provisions of subsection (iv) above shall to the
         full extent applicable, and for so long as the same shall be
         applicable, be deemed without further act or instrument incorporated by
         reference in the Citibank Lease as if set forth at length therein. Upon
         the request of either party, Seller and Purchaser shall enter into a
         written amendment to the Citibank Lease memorializing the incorporation
         therein of any provisions deemed incorporated into the Citibank Lease
         pursuant to the preceding sentence, provided that the failure of the
         parties to enter into any such written amendment shall not affect the
         validity or applicability of any such provisions.

         (c) The parties hereto expressly intend that the provisions of this
Section 16 and not Section 5-1311 of the New York State General Obligations Law,
shall govern in the event of a fire or other casualty.

                                      -53-


         17. CONDEMNATION.

         (a) If, between the date hereof and the Closing, fifty percent (50%) or
more (measured by square footage) of the floor space of Citigroup Center shall
be subject to a permanent taking or appropriation for public or quasi-public use
under the power of eminent domain or a condemnation proceeding (a "Major
Condemnation"), each of Purchaser and Seller shall have the right, exercisable
by giving written notice to the other within ten (10) days after receiving
written notice of such taking or appropriation, to terminate this Agreement, in
which case neither party shall have any further rights or obligations hereunder
except such obligations which expressly survive the termination of this
Agreement. If, between the date hereof and the Closing, any condemnation or
eminent domain proceedings are initiated which would result in the taking of all
or any portion of the Unit, or any other portion of Citigroup Center other than
a Major Condemnation, neither Seller nor Purchaser shall have the right to
terminate this Agreement. In such event, or in the event of a Major Condemnation
as to which neither party shall exercise the termination option contained in the
first sentence of this subsection, then (i) the parties shall proceed to Closing
without reduction of or offset against any amounts payable hereunder or any
other claim against the other, (ii) at the Closing, Seller shall assign and turn
over, and Purchaser shall be entitled to receive and keep any condemnation
proceeds in respect thereof, subject to the terms of the Condominium
Declaration, and (iii) the parties hereto shall cooperate in all reasonable
respects in order to effectuate such intent. The provisions of this Section 17
shall survive the Closing for a period without expiration.

         (b) The parties hereto expressly intend that the provisions of this
Section 17 and not Section 5-1311 of the New York State General Obligations Law,
shall govern in the event of a taking.


         18. REMEDIES.

     If the Closing fails to occur by reason of the failure or refusal of either
party to perform its obligations hereunder (for purposes of this Section 18, the
"Defaulting Party"), then the other party (for purposes of this Section 18, the
"Non-Defaulting Party") may terminate this Agreement by notice to the Defaulting
Party and/or the Non-Defaulting Party may avail itself of all rights and
remedies at law or in equity, including, without limitation, the remedy of
specific performance. Nothing contained in this Section shall be construed to
limit either party's right to enforce any covenant or indemnity which, pursuant
to the provisions of this Agreement, is specified to survive the Closing, nor to
prevent either party from proceeding against the other in an action at law for
the recovery of actual damages (but not punitive damages) suffered as a result
of the inaccuracy of any representation or warranty

                                      -54-


which, pursuant to the provisions of this Agreement, is specified to survive the
Closing, subject to any other limitations contained herein.

         19. INDEMNITIES.

         (a) SELLER'S INDEMNITY . Seller hereby agrees to indemnify Purchaser
and the other Purchaser Indemnified Parties against, and to hold Purchaser and
the other Purchaser Indemnified Parties harmless from, all claims, demands,
causes of action, losses, damages, liabilities, costs and expenses (including,
without limitation, reasonable attorneys' fees and disbursements) asserted
against or incurred by Purchaser or any of the other Purchaser Indemnified
Parties in connection with or arising out of (i) acts or omissions of Seller or
Seller's Representatives, or other matters or occurrences that take place before
the Closing and relate to the ownership, maintenance or operation of the Unit
(except to the extent caused by Purchaser's veto of any matter that is submitted
to Purchaser as a Purchaser Consent Action) including, without limitation, all
losses, costs, damages and expenses incurred by Purchaser and the other
Purchaser Indemnified Parties arising from audits performed by current or former
tenants of the Unit relating to escalations and pass-throughs charged by Seller
prior to the Closing, or (ii) a breach of any representation, warranty or
covenant of Seller contained in this Agreement. Seller's obligations under this
Section 19(a) shall survive the Closing for a period of two (2) years.

         (b) PURCHASER'S INDEMNITY . Purchaser hereby agrees to indemnify Seller
and the other Seller Indemnified Parties against, and to hold Seller and the
other Seller Indemnified Parties harmless from, all claims, demands, causes of
action, losses, damages, liabilities, costs and expenses (including, without
limitation, reasonable attorneys' fees and disbursements) asserted against or
incurred by Seller or any of the other Seller Indemnified Parties in connection
with or arising out of (i) acts or omissions of Purchaser or Purchaser's
Representatives, or other matters or occurrences that take place after the
Closing and relate to the ownership, maintenance or operation of the Unit, or
(ii) a breach of any representation, warranty or covenant of Purchaser contained
in this Agreement. Purchaser's obligations under this Section 19(b) shall
survive the Closing for a period of two (2) years.

         (c) NOTICE OF CLAIMS TO BE INDEMNIFIED. Whenever in this Agreement it
is provided that any party shall indemnify and hold harmless the other party,
then, as a condition to such indemnity the terms of this Section 19(c) shall
apply. The party indemnified shall promptly give written notice to the
indemnitor of any claim or demand made upon it which is or may be indemnified
against. The indemnitor shall have the right to defend against such claim or
demand by counsel selected by indemnitor's liability insurer or such other
counsel selected by indemnitor and reasonably satisfactory to the indemnified
party. The indemnified party shall reasonably cooperate with indemnitor, at
indemnitor's expense. The indemnified

                                      -55-


party shall not settle or approve the settlement of any claim without the
approval of the indemnitor, which approval shall not be unreasonably withheld or
delayed. Any separate counsel retained by the indemnified party shall be at its
own expense.

         20. ASSIGNMENT AND RECORDING.

         (a) Except as hereinafter provided, neither this Agreement nor any of
the rights or obligations hereunder may be assigned without the prior written
consent of the other parties hereto. Seller shall be entitled, without the need
for further notice to any other party, to assign its interests in this Agreement
to the Exchange Intermediary in the manner contemplated by the Exchange
Agreement. DLIP (but no other person or party which may hereafter be deemed to
be the "Purchaser" under this Agreement) shall be entitled, upon giving prior
written notice to Seller, to either assign its rights under this Agreement to
any person or entity provided such person or entity expressly assumes the
obligations of Purchaser hereunder pursuant to a written instrument in form and
substance reasonably satisfactory to Seller (but expressly excluding therefrom
any approval rights as to the identity of any assignee of Purchaser) or to
otherwise designate a person or party to whom title to the Unit shall be
conveyed, it being further understood and agreed that notwithstanding such
assignment and assumption or designation, as the case may be, Purchaser shall
not be relieved of any of its obligations under this Agreement and Seller shall
need only to look to DLIP and no other person or party for the performance of
Purchaser's obligations hereunder.

         (b) Neither this Agreement nor any memorandum of this Agreement may be
recorded without the prior written consent of the parties hereto.


         21. PROPERTY INFORMATION AND CONFIDENTIALITY.

         (a) Each of Seller and Purchaser (for purposes of this Section 21, each
a "Confidential Party") agrees that, prior to the Closing, all Property
Information shall be kept strictly confidential and shall not, without the prior
consent of the other, be disclosed by such Confidential Party or such
Confidential Party's Representatives, in any manner whatsoever, in whole or in
part, and will not be used by such Confidential Party or such Confidential
Party's Representatives, directly or indirectly, for any purpose other than
evaluating and consummating the transactions contemplated by this Agreement
(including, with respect to Purchaser, any assignment or designation described
in subsection 20(a)). Moreover, each Confidential Party agrees that, prior to
the Closing, the Property Information will be transmitted only to such
Confidential Party's Representatives (and, in the case of DLIP, any permitted
potential assignee or designee of DLIP's rights under this Agreement and such
assignee's or designee's Representatives and the Representatives of such
assignee's or designee's potential lenders) who need to know the Property
Information for the purpose of evaluating the transactions contemplated by this
Agreement or the financing thereof, and who

                                      -56-


are informed by such Confidential Party of the confidential nature of the
Property Information (and, in the case of any permitted potential assignee or
designee of DLIP's rights under this Agreement, who have entered into a
confidentiality agreement substantially in the form of Exhibit V attached hereto
or in such other form as is mutually and reasonably acceptable to Seller and
DLIP). The provisions of this Section 21 shall in no event apply to Property
Information which is a matter of public record and shall not prevent a
Confidential Party from complying with any laws or governmental ordinances,
rules, regulations, orders or requirements, including, without limitation,
governmental regulatory, disclosure, tax and reporting requirements.

         (b) Each of Seller and Purchaser, for the benefit of the other, hereby
agrees that between the date hereof and the Closing Date, it will not release or
cause or permit to be released any press notices, publicity (oral or written) or
advertising promotion relating to, or otherwise announce or disclose or cause or
permit to be announced or disclosed, in any manner whatsoever, the terms,
conditions or substance of this Agreement or the transactions contemplated
herein, without first obtaining the written consent of the other party hereto,
which consent shall not be unreasonably withheld, conditioned or delayed. It is
understood that the foregoing shall not preclude Seller or Purchaser from
discussing the substance or any relevant details of the transactions
contemplated in this Agreement, subject to the terms of Section 21(a) above,
with any of its attorneys, accountants, professional consultants or potential
lenders, as the case may be, or prevent Seller or Purchaser from complying with
any laws or governmental ordinances, rules, regulations, orders or requirements,
including, without limitation, governmental regulatory, disclosure, tax and
reporting requirements.

         (c) In the event this Agreement is terminated, each Confidential Party
and such Confidential Party's Representatives shall promptly deliver to the
other party to this Agreement all originals and copies of the Property
Information referred to in clause (i) of Section 21 (d) below in the possession
of such Confidential Party and such Confidential Party's Representatives.

         (d) As used in this Agreement, the term "Property Information" shall
mean (i) all information and documents in any way relating to the Unit, the
operation thereof or the sale thereof (including, without limitation, Leases and
Contracts) furnished to, or otherwise made available for review by, a
Confidential Party or its Representatives (or, in the case of DLIP, any
permitted potential assignee or designee of DLIP's rights under this Agreement
and such assignee's or designee's Representatives and the Representatives of
such assignee's or designee's potential lenders), by the other party to this
Agreement, or any of such other party's affiliates, or their agents or
representatives, including, without limitation, their contractors, engineers,
attorneys, accountants, consultants, brokers or advisors, and (ii) all analyses,
compilations, data, studies, reports or other information or documents prepared

(a) The Sale Property Proceeds have been deposited with the Qualified Intermediary, with the result that the total capital in the Company immediately prior to the Effective Date is zero (excluding such Sale Property Proceeds which are then held by the Qualified Intermediary for the benefit of the Company). The Company, at the Ceppeto Members request, shall cause the Qualified Intermediary to apply (and the BP Members hereby consent to such application) $150,891,083.78 of the Sale Property Proceeds toward the acquisition of the Property by the Company (it being acknowledged that any interest earned thereon may be disbursed directly by the Qualified Intermediary to the Ceppeto Members, in accordance with the Master Transaction Agreement).

In consideration of such deemed contribution, the Company has issued 115.89108378 Preferred Units to Ceppeto, and Ceppeto holds $33,340,198.08 in Class B Common Equity and Ceppeto Holdings holds $1,659,801.92 in Class B Common Equity.

Immediately following such contribution by Ceppeto, the remaining Preferred Units (and Preferred Equity) then held by Ceppeto are reclassified as Senior Preferred Equity, evidenced by such Preferred Units. As a result of such contribution and reclassification, Ceppeto continued to hold 3.69108378 Preferred Units, which Preferred Units are evidence of $3,691,083.78 of Senior Preferred Equity. For all purposes of this Agreement, BP Member II is treated as having made an Initial Capital Contribution that is deemed to be the value of the Preferred Units contributed to BPLP by Ceppeto, and BP Member II is the holder of 112.2 Preferred Units (including the Preferred Equity in connection therewith in the amount of $112,200,000). As of the Effective Date, neither Ceppeto nor Ceppeto Holdings holds any Class A Common Equity or Preferred Equity and neither BP Member II nor BP Member III holds any Class A Common Equity. Ceppeto does, however, hold Preferred Units evidencing Senior Preferred Equity as provided herein. Each Member's Initial Capital Contribution will constitute such Member's Capital Account. 4.2.

In addition to the Management Agreement, the Managing Member, on behalf of the Company, may enter into any agreement in the ordinary course of managing the Property with one of its Affiliates, provided that the terms of any such agreement (including any replacement of the Management Agreement, which shall, in all events be subject to SECTION 6.4(a) of this Agreement) are no less favorable than the Company would have obtained in a like transaction negotiated at arms-length with an unaffiliated third party. The Managing Member shall notify the Ceppeto Members of the material terms of any such agreements and shall enforce the economic terms of all such agreements. 6.7. NON-INTERFERENCE COVENANT. Subject to the Ceppeto Members' rights, if any, under the final paragraph of SECTION 6.5, each Ceppeto Member agrees that it will not (i) interfere or attempt to interfere (and will cause its Affiliates, and all Persons claiming by or through any of them, not to interfere) directly or indirectly with the conduct of the business of the Company by the Managing Member or the right of the Managing Member to control and manage the Company, the Company's business and the Property, or the taking or failure to take any action by the Managing Member hereunder or (ii) take any action which the Managing Member is authorized or otherwise permitted to take under this Agreement. If either Ceppeto Member or any of its Affiliates or any Person claiming by or through any of them, breaches the foregoing covenant, then the Managing Member shall have the right to deliver a written notice of such breach to the Ceppeto Members at any time within ninety (90) days after such breach (each, a "BREACH Notice"). If either Ceppeto Member or any of its Affiliates or any Person claiming by or through any of them, breaches the foregoing covenant at any time after the Managing Member shall have previously delivered two (2) valid, bona fide Breach Notices, then the Managing Member shall have the option, exercisable by giving notice to the Ceppeto Members at any time within ninety (90) days after such breach, to acquire the Ceppeto Members' entire interest in the Company for a purchase price equal to ninety-five percent (95%) of the amount that would have been distributable to the Ceppeto Members under SECTION 9.3(b) or 9.4(b), as applicable, if the Property had been sold at Fair Market Value as of the date such notice of acquisition is given by the Managing Member, as determined by an appraiser selected in accordance with the procedure set forth in SECTION 12.2, less (i) the amount of any reserves established by the Managing Member, in its reasonable discretion, in consideration of any potential indemnification obligations of the Ceppeto Indemnitors' pursuant to SECTION 13.5 and (ii) the sum of applicable transfer taxes incurred as a result of such sale plus three percent (3%) of the distributable amount, which the parties hereto unconditionally agree is a reasonable estimate and 32 approximation of customary closing costs which would be associated with similar transactions (provided however, that in consideration of the agreed upon reduction of such Fair Market Value by the amount of the transfer taxes which would be incurred in connection with a sale of the Property for such amount, the Managing Member agrees to pay any transfer taxes actually payable in connection with the conveyance contemplated hereunder, and shall indemnify the Ceppeto Members from and against any cost or expense resulting from the failure to pay such amounts as and when due). Any such reserves shall be retained by the BP Member as collateral for the Ceppeto Indemnitors' indemnification obligations under SECTION 13.5 and shall be maintained in an interest-bearing account (all such interest to be retained in such account, and to be earned for the benefit of the Ceppeto Members) at a commercial bank, trust company, savings bank or other similar institutions selected by the BP Member and reasonably acceptable to the Ceppeto Members. Any and all risk of loss with respect to such account shall be borne solely and exclusively by the Ceppeto Members. All amounts contained in such account will be remitted to the Ceppeto Members if, as and when the pledge of the Ceppeto Members' Equity Interest would have been released pursuant to SECTION 13.5(e)(3). Nothing contained in this SECTION 6.7 shall limit or otherwise affect the Ceppeto Indemnitors' indemnification obligations contained in SECTION 13.5. The Ceppeto Members shall assign their entire equity interest in the Company to the Managing Member, or its designee, free and clear of any and all claims, liens, pledges, restrictive covenants, charges, hypothecations, preferences, priorities, security interests or other encumbrances of any kind or nature, and shall provide customary representations and indemnifications in connection therewith. The closing of such assignment shall occur on a date determined by the Managing Member, which date shall be within thirty (30) days after the determination, as set forth above, of the amount to be paid for the Ceppeto Members' equity interest. Upon the consummation of any such assignment of the Ceppeto Members' equity interest, the Ceppeto Members shall be deemed to have withdrawn from the Company and shall have no further right, claim or interest in and to the Company. The grant of this option to the Managing Member is intended to establish a measure of liquidated damages for the costs, expenses and damages that would be suffered by the Boston Properties Members in the event of a breach by either Ceppeto Member of the covenant set forth in this SECTION 6.7, since the actual damages that might be sustained by the Boston Properties Members in such event would be extremely difficult if not impossible to ascertain having regard to the long-term impact on the Boston Properties Members' economic interests, the potential dislocation of its resources and the potential damage to reputation that might result from such a breach. The Ceppeto Members acknowledge that the exercise of such option would afford the Boston Properties Members a reasonable measure of damages under the circumstances. it is the intent of the parties to this Agreement that the requirements or obligations of the Ceppeto Members to sell its equity interest in the Company to the Managing Member, or its designee, hereunder shall be enforceable by an action for specific performance of a contract relating to the purchase of real property or an interest therein. In the event that the Ceppeto Members shall have created or suffered any unauthorized liens, encumbrances or other adverse interests against either the Property or the Ceppeto Members' interests in the Company, the Managing Member shall be entitled either to an action for specific performance to compel the Ceppeto Members to have such defects removed, at the Ceppeto Members' expense, in which case the closing shall be adjourned for such purpose, 33 or, at the Managing Members' option, to an appropriate offset against the purchase price, which offset shall include all reasonable costs associated with enforcement of this Section. 6.8. PROCEEDS OF ADDITIONAL FINANCING. In connection with any refinancing of the Senior Loan (the "REFINANCING"), the Managing Member intends to use commercially reasonable efforts to maximize the net proceeds from such Refinancing so as to allow the repayment in full of the Preferred Equity upon the making of distributions in connection with such Refinancing in accordance SECTION 9.3(b); PROVIDED, HOWEVER, that the Managing Member shall have no obligation to enter into any particular Refinancing agreement (or enter into any Refinancing at all), or to obtain any specific loan amount upon Refinancing or to otherwise accept any terms, conditions or other provisions (including financial and other covenants, interest rate, loan to value and/or debt service coverage ratios) that are not acceptable to the Managing Member in its sole and absolute discretion. Without limiting the generality of the foregoing, the Managing Member shall in no event be obligated to enter into any Refinancing, the terms of which would require (a) the Company or any direct or indirect beneficial owner of the Company to provide guaranties or incur recourse obligations of any kind or nature, except for environmental indemnities and then-customary carve-outs or exceptions for commercial non-recourse loans, or (b) the payment of interest at a rate that is higher than the lower of (1) the interest rate payable on the Senior Loan or (2) then prevailing interest rates for comparable first mortgage loans (without equity participations or similar features). The Managing Member intends to structure the Refinancing in consideration of the tax consequences of such Refinancing to the Ceppeto Members, provided that such structure (i) does not adversely impact the Boston Properties Members or their Affiliates, the Property or the Refinancing (all as determined by the Managing Member) and (ii) does not cause the Boston Properties Members or their Affiliates or the Property in connection with the contemplated Refinancing, to incur any additional cost or other liability. Notwithstanding the foregoing, in the event and to the extent any such Refinancing or any subsequent refinancing thereof is treated as a recourse liability under Regulations Section 1.752-1(a)(1) allocable to the Boston Properties Members, the Ceppeto Members or their designees (in such proportion among themselves as they shall determine) shall have the right to guarantee a portion of such loan in an amount up to the amount of such Refinancing which is otherwise allocable to the Boston Properties Members under Section 752 of the Code multiplied by the Ceppeto Members' Percentage Interests in the Company in such a manner that results in such portion of the loan being allocated to the Ceppeto Members under Section 752 of the Code. Such guaranty shall be in a form reasonably acceptable to the applicable lender, the Ceppeto Members and the Managing Member. The Managing Member shall notify the Ceppeto Members not less than fifteen (15) Business Days prior to the anticipated date of any Refinancing which the Managing Member, in good faith, believes is available to be guaranteed by the Ceppeto Members hereunder, which notice shall specify (i) the expected date of such Refinancing, (ii) the Managing Member's good faith estimate of the amount available to be guaranteed by the Ceppeto Members thereunder (which estimate shall not be binding upon the Managing Member) and (iii) such other matters as the Managing Member shall determine. The Ceppeto Members shall notify the Managing Member, within four (4) Business Days after its receipt of such notice of its intention to provide such guaranty. In the event that the Ceppeto Members elect to provide such guaranty, the Managing Member and the Ceppeto Members shall thereafter cooperate in good faith in connection with 34 the consummation of such Refinancing and the delivery of any applicable guaranties. The Managing Member shall notify the Ceppeto Members not less than fifteen (15) Business Days prior to the anticipated date of any Refinancing, which notice shall, if an executed commitment or detailed term sheet in lieu of a commitment with respect to such proposed Refinancing has then been entered into, describe the material terms of such Refinancing (or, if no such commitment or detailed term sheet then exists, but is subsequently entered into, the Managing Member shall promptly thereafter notify the Ceppeto Members of the material terms of such Refinancing). Notwithstanding anything to the contrary, the Managing Member shall have the right to consummate the Refinancing (or to not consummate the Refinancing) on terms satisfactory to the Managing Member in its sole discretion provided that this sentence shall not limit or affect the Ceppeto Members right, if and when applicable, to provide a guaranty of any applicable recourse Refinancing, as provided above.

In addition to the establishment and maintenance of Capital Accounts pursuant to SECTION 7.9, the Company shall keep such other books and records as the Managing Member shall determine.

Unless otherwise determined by the Managing Member, such tax returns shall be prepared by independent certified public accountants selected pursuant to SECTION 7.6, who shall sign such returns as preparers. The Company shall submit the returns to each Member for review and approval (which approval shall not be unreasonably withheld, conditioned or delayed) no later than thirty (30) days prior to the due date of the returns, but in no event later than March 15th of each year.

The Tax Matters Partner shall comply with the requirements of Section 6221 through 6232 of the Code. The Tax Matters Partner shall have the authority, to select and appoint independent certified public accountants to prepare tax returns and annual audited financial statements for the Company, the expense of which shall be borne by the Company. The Members acknowledge that, immediately prior to the Effective Date, Ceppeto was the Tax Matters Partner for the Original Company and the Company, and shall continue as the Tax Matters Partner for the Original Company (but not for the Company) for the period ending December 31, 2000, and shall, subject to obtaining the prior written consent of the Managing Member with respect thereto, which consent shall not be unreasonably withheld or delayed, be responsible for the filing of the 2000 tax returns for the Original Company for the period ending on December 31, 2000, PROVIDED HOWEVER, that Ceppeto shall comply with the requirements of Section 6221 through 6232 of the Code with respect to such prior periods and in no event shall the Tax Matters Partner (from and after the Effective Date) or the Company be bound by any election or position taken by Ceppeto in connection with the preparation of or filing of the tax returns and annual audited financial statements for the Company, nor shall Ceppeto take any position or make any election in connection therewith which would bind the Company or the Tax Matters Partner from and after the Effective Date without the consent of the Tax Matters Partner, which consent shall not be unreasonably withheld. 7.7.

The following terms shall have the following meanings when used herein: (a) "OPERATING CASH FLOW" means the net income or loss of the Company for the fiscal period in question, as determined in accordance with generally accepted accounting principles, consistently applied and adjusted as follows or as otherwise determined by the Managing Member: (1) ADDITIONS. There shall be added to such net income or subtracted from such loss (A) the amount charged for depreciation, amortization or any other deduction not involving a cash expenditure, (B) the amount of Capital Contributions to the Company to the extent not used in connection with the acquisition of the Property or the creation of the Operating Expense Reserve, (C) the costs and expenses attributable to a Capital Event to the extent deducted in the determination of net income or loss, and (D) any amount by which cash reserves previously established by the Managing Member from Operating Cash Flow in order to retain sufficient working capital in the Company or to properly reserve for actual or contingent obligations of the Company or improvements to the Property have been reduced (other than through the payment of such obligations). (2) DEDUCTIONS. There shall be subtracted from such net income or added to such loss (A) payments of principal made on account of the Senior Loan and any other loans made to the Company, (B) funds disbursed for capital expenditures, leasing commissions, tenant finish or any other similar expenses that are required to be capitalized, (C) the proceeds of a Capital Event to the extent included in net income or loss, (D) the fees paid pursuant to the Management Agreement to the extent not previously deducted in calculating net income or loss, and (E) any amount to establish or increase cash reserves pursuant to a determination of the Managing Member that such reserve or increase to an 39 existing reserve is necessary or appropriate in order to retain sufficient working capital in the Company or to properly reserve for other actual or contingent obligations of the Company or improvements to the Property, including without limitation, reserves required pursuant to the documents evidencing the Senior Loan.

The Company shall distribute Capital Event Proceeds within three (3) Business Days after the Company receives Capital Event Proceeds from any Capital Event that occurs subsequent to the Flip Date to the Members as follows: (1) FIRST, (A) to the Members in respect of Senior Preferred Equity, if any, on a pari passu basis in proportion to the sum of each such Member's aggregate unreturned Senior Preferred Equity until such Members have received distributions equal to their respective aggregate unreturned Senior Preferred Equity, provided however that notwithstanding the foregoing, (i) no more than $307,590.31 may be distributed in any one month (plus any portion of such amounts (i.e., $307,590.31) not distributed during any prior month) and (ii) in no event shall the aggregate distributions in consideration of Senior Preferred Equity at any time exceed amounts expended by the Company out of the Operating Expense Reserve prior to the date of such distribution, AND THEN (B) to the Members in respect of Additional Preferred Equity, if any, on a pari passu basis in proportion to the sum of each such Member's aggregate unreturned Additional Preferred Equity and accrued (and compounded but) unpaid Additional Preferred 43 Equity Return, until such Members have received distributions equal to their respective aggregate unreturned Additional Preferred Equity and aggregate accrued (and compounded but) unpaid Additional Preferred Equity Return; (2) SECOND, to the holders of Class B Common Equity on a pari passu basis until such holders have received distributions equal to the aggregate accrued (and compounded but) unpaid Class B Common Return, if any; (3) THIRD, to the holders of Preferred Equity and Class A Common Equity, on a pari passu basis until each such holder has received distributions equal to the sum of its aggregate accrued (and compounded but) unpaid shares of (i) the Adjusted Preferred Balance Return and (ii) the Preferred Return and Class A Common Return as of the Flip Date and (iii) the Class A Common Return for the period commencing on the Flip Date and ending on the Priority Payment Cessation Date; (4) FOURTH, to the Members to repay the Preferred Equity on a pari passu basis in proportion to the Preferred Equity held by each Member until the Preferred Equity has been repaid in its entirety; (5) FIFTH, to the Members to repay the Common Equity on a pari passu basis in proportion to the Common Equity held by each Member until the Common Equity has been repaid in its entirety; and (6) THEREAFTER, to the Members in accordance with their Percentage Interests.

For example, (i) the aggregate amount distributed pursuant to SECTION 9.3(b)(4) or SECTION 9.4(b)(5) in repayment of the BP Member's Common Equity shall be limited to the aggregate amount of the BP Member's Capital Contributions attributable to Common Equity minus any such amounts previously or contemporaneously distributed pursuant to SECTION 9.3(b)(4) and SECTION 9.4(b)(5) in repayment of the BP Member's Common Equity and (ii) the Class B Common Return shall only accrue and be payable, as and to the extent applicable, commencing on the Flip Date through and including the Priority Payment Cessation Date.

(7) Seventh, in any fiscal year in which a distribution is made to the holders of Class A Common Equity and Class B Common Equity pursuant to SECTIONS 9.4(a)(5) and 9.4(b)(6), net income shall be allocated 100% to such holders in proportion to and to the extent of such distributions in such fiscal year. (8) Eighth, in any fiscal year in which the aggregate amount of the distributions made to the holders of Class A Common Equity and Class B Common Equity pursuant to SECTIONS 9.4(a)(5) and 9.4(b)(6) in all prior fiscal years exceeds the aggregate amount of net income allocated to such Member pursuant to SECTION 9.5(c)(7) and this SECTION 9.5(c)(8) in all prior fiscal years, net income shall be allocated 100% to such holders in proportion to and to the extent of such distributions in all prior fiscal years, until the excess of the aggregate amount distributed pursuant to SECTIONS 9.4(a)(5) and 9.4(b)(6) for all fiscal years over the aggregate amount of net income allocated to such Members pursuant to SECTIONS 9.5(c)(7) and 9.5(c)(8) for all fiscal years is equal to zero.

(10) Notwithstanding anything to the contrary above, 100% of the gain recognized in connection with a sale or other disposition of the Property shall be allocated to the Members in such amounts as are required to cause each Member's adjusted capital account balance to equal, to the greatest extent possible, the distributions each such Member would receive upon liquidation of the Company at such time if such distributions were made pursuant to the provisions of SECTION 9.3(b) or 9.4(b) as applicable; 47 (11) LOSS LIMITATION. Notwithstanding anything to the contrary in SECTION 9.5(b)(5), net loss allocated pursuant to SECTION 9.5(b) shall not exceed the maximum amount of net loss that can be allocated without causing or increasing a deficit balance in any member's adjusted capital account. A Member's "adjusted capital account" balance shall mean the Member's capital account balance increased by its obligation to restore a deficit balance in its Capital Account, if any, including any deemed obligations pursuant to the penultimate sentences of Treasury Regulations Sections 1.704-2(g)(1) and 1.704-2(i)(5), and decreased by the amounts described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6). In the event that a Member would have a deficit balance in its adjusted capital account as a consequence of an allocation of net loss pursuant to SECTION 9.5(b) in excess of the amount, if any, permitted under the first sentence of this SECTION 9.5(c)(11) the limitation set forth herein shall be applied by allocating 100% of the remaining net loss to the other Members, in proportion to each such Member's positive adjusted capital account balance immediately prior to such loss allocation. Any net income allocated by the Company after an allocation of net loss under the prior sentence shall first be allocated to the Members to which such net loss was allocated, in the same ratio and amount. (d) MINIMUM GAIN CHARGEBACKS AND NONRECOURSE DEDUCTIONS. (1) PARTNERSHIP MINIMUM GAIN CHARGEBACK. Notwithstanding any other provision of this Agreement, in the event there is a net decrease in Partnership Minimum Gain during a fiscal year, the Members shall be allocated items of income and gain in accordance with Treasury Regulations Section 1.704-2(f). For purposes of this Agreement, the term "Partnership Minimum Gain" shall have the meaning for partnership minimum gain set forth in Treasury Regulations Section 1.704-2(b)(2), and any Member's share of Partnership Minimum Gain shall be determined in accordance with Treasury Regulations Section 1.704-2(g)(1). This SECTION 9.5(d) is intended to comply with the minimum gain chargeback requirement of Treasury Regulations Section 1.704-2(f) and shall be interpreted and applied in a manner consistent therewith. (2) NONRECOURSE DEDUCTIONS. Notwithstanding any other provision of this Agreement, Nonrecourse Deductions shall be allocated to the Members' pro rata in accordance with their Percentage Interests. For purposes of this Agreement, the term "Nonrecourse Deductions" shall have the meaning set forth in Treasury Regulations Section 1.704-2(b)(1). This SECTION 9.5(d)(2) is intended to comply with Treasury Regulations Section 1.704-2(e) and shall be interpreted and applied in a manner consistent therewith. (3) PARTNER NONRECOURSE DEBT. Notwithstanding any other provision of this Agreement, to the extent required by Treasury Regulations Section 1.704-2(i), any items of income, gain, loss or deduction of the Company that are 48 attributable to a nonrecourse debt of the Company that constitutes Partner Nonrecourse Debt (including chargebacks of Partner Nonrecourse Debt Minimum Gain) shall be allocated in accordance with the provisions of Treasury Regulations Section 1.704-2(i). For purposes of this Agreement, the term "Partner Nonrecourse Debt" shall have the meaning for partner nonrecourse debt set forth in Treasury Regulations Section 1.704-2(b)(4), and the term "Partner Nonrecourse Debt Minimum Gain" shall have the meaning for partner nonrecourse debt minimum gain set forth in Treasury Regulations Section 1.704-2(i)(2). This SECTION 9.5(d)(3) is intended to satisfy the requirements of Treasury Regulations Section 1.704-2(i) (including the partner nonrecourse debt minimum gain chargeback requirement) and shall be interpreted and applied in a manner consistent therewith. (e) QUALIFIED INCOME OFFSET. If a Member unexpectedly receives an adjustment, allocation or distribution described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6) that causes or increases a deficit balance in its Capital Account in excess of any obligation to restore a deficit balance in its Capital Account (including any deemed deficit restoration obligation pursuant to the penultimate sentences of Treasury Regulations Sections 1.704-2(g)(1) and (i)(5), and adjusted as provided in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)) such Member shall be allocated items of income and gain in an amount and a manner sufficient to eliminate, to the extent required by the Treasury Regulations, such deficit balance as quickly as possible. This SECTION 9.5(e) is intended to comply with the alternate test for economic effect set forth in Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted and applied in a manner consistent therewith. (f) CURATIVE ALLOCATIONS. The allocations set forth in Sections 9.5(d) and (e) (the "REGULATORY ALLOCATIONS") are intended to comply with the requirements of Treasury Regulations Sections 1.704-1(b) and 1.704-2. Notwithstanding any other provisions of this ARTICLE 9 (other than the Regulatory Allocations), the Regulatory Allocations shall be taken into account as provided for in the following two sentences. Income, gain, loss and deduction shall be reallocated to the extent that such reallocation causes the net aggregate amount of allocations of income, gain, deduction and loss to each Member to be equal to or more closely approximate the net aggregate amount of such items that would have been allocated to each such Member if the Regulatory Allocations had not occurred. This SECTION 9.5(f) shall be interpreted and applied in such a manner and to such extent as is reasonably necessary to eliminate, as quickly as possible permanent economic distortions that would otherwise occur as a consequence of the Regulatory Allocations in the absence of this SECTION 9.5(f). (g) DISTRIBUTIONS OF NONRECOURSE LIABILITY PROCEEDS. If, during a fiscal year, the Company makes a distribution to any Member that is allocable to the proceeds of any nonrecourse liability of the Company that is allocable to an increase in Partnership Minimum Gain pursuant to Treasury Regulations Section 1.704-2(h), then the Company shall elect, to the extent permitted by Treasury Regulations Section 1.704-2(h)(3), to treat 49 such distribution as a distribution that is not allocable to an increase in Partnership Minimum Gain. (h) PRIOR PERIOD ALLOCATIONS. Allocations with respect to the period ending on the day prior to the Effective Date shall be made using an interim closing of the books method as provided under Section 706 of the Code and the Regulations thereunder. 9.6. DISTRIBUTIONS AND ALLOCATIONS UPON LIQUIDATION OF THE COMPANY. (a) DISTRIBUTIONS UPON LIQUIDATION. In the event the Company (or any Member's interest therein) is "liquidated" within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(g), then any distributions shall be made pursuant to this SECTION 9.6 to the Members (or such Member, as appropriate) in accordance with their positive Capital Account balances in compliance with Treasury Regulations Section 1.704-1(b)(2)(ii)(b)(2). (b) DEFICIT RESTORATION BY COMPANY. Except as provided herein, no Member shall be required to contribute capital to the Company to restore a deficit balance in its Capital Account upon liquidation or otherwise. (c) ALLOCATIONS OF INCOME AND LOSS IN THE YEAR OF LIQUIDATION. Notwithstanding anything to the contrary above, in the year in which the Company is "liquidated" within the meaning of SECTION 9.6(a), items of income, gain, loss and deduction shall be allocated to the Members (and, to the extent necessary to accomplish the purposes of this SECTION 9.6(c), the items of income, gain, loss and deduction of the prior fiscal year, provided any such determination with respect to allocations of such items in the prior fiscal year shall be made on or before the date on which the filing of the return for such prior fiscal year is due) shall be allocated among the Members to cause each such Member's adjusted capital account balance to equal, to the greatest extent possible, the distribution such Member would be entitled to receive pursuant to the provisions of SECTION 9.3(b) or 9.4(b), as applicable, at such time, in the event liquidating distributions were made pursuant to either of such sections in lieu of the provisions of SECTION 9.6(a) above. (d) The Members agree that allocations of depreciation with respect to the Property shall be made pursuant to the remedial allocation method of Treasury Regulation Section 1.704-3(d). 9.7. RECAPTURE INCOME. To the extent of any net income resulting from the sale or other taxable disposition, directly or indirectly, of a Company asset that represents the recapture (under Section 1245 or Section 1250 of the Code or otherwise) of deductions previously taken for Federal income tax purposes, the amount of gain from such disposition allocated to each of the Members pursuant to the foregoing provisions shall be recapture income to the extent such Member or a predecessor-in-interest has been allocated or has claimed any deduction directly or indirectly giving rise to the treatment of such gain as recapture income. 50 ARTICLE 10. ASSIGNMENT AND OFFER TO PURCHASE 10.1. SALE OF THE PROPERTY. (a) The Managing Member shall have the sole and exclusive power and authority to cause a sale, transfer, conveyance or other similar disposition of the Property or any portion thereof by operation of law or otherwise, either directly or indirectly through the sale of the Property or other disposition of the Company's interests in BP/CGMM2, BP/CGMM, BP/CG I or BP/CG II or any other Person owned by the Company that directly or indirectly owns the Property or any portion thereof (a "PROPERTY TRANSFER"), and no other Member shall have the right, power or authority to do so. Notwithstanding the foregoing, prior to the expiration of the Tax Protection Period, the Managing Member shall not have the authority to cause a Property Transfer without the prior written consent of the Ceppeto Members, which consent may be granted or withheld in the Ceppeto Members' sole and absolute discretion. Any time after the expiration of the Tax Protection Period, the Managing Member may cause a Property Transfer in its sole and absolute discretion, PROVIDED it first complies with SECTION 10.1A. Notwithstanding anything to the contrary contained herein, in no event shall a Property Transfer hereunder be deemed to include any conveyances or other dispositions which are not in the nature of a sale and which for federal income tax purposes would not be treated as a sale or other taxable disposition of the Property, such as, by way of example only, space leases, contracts, pledges, mortgages, easements and other encumbrances; PROVIDED that such conveyances or other dispositions are not made for the principal purpose of avoiding the terms and conditions of this SECTION 10.1. (b) Notwithstanding anything to the contrary contained in this Agreement, at any time when the Managing Member has notified the Members that the Property is being actively marketed as permitted under this SECTION 10.1, (1) each Member's right to sell its interest in the Company (such Member's "EQUITY INTEREST") pursuant to the terms of this ARTICLE 10 (other than pursuant to a Permitted Equity Transfer) shall be suspended and (2) each Member shall suspend all marketing efforts or negotiations that may have been commenced with respect to a sale of its Equity Interest; PROVIDED, HOWEVER, that nothing contained in this SECTION 10.1(b) shall require either Member to suspend any activity undertaken pursuant to SECTION 10.7 of this Agreement or delay or otherwise effect the Managing Member's rights pursuant to SECTION 6.7. Upon the request therefor by the Ceppeto Members, the Managing Member shall confirm whether it is continuing to actively market the Property or has suspended such marketing. 10.1A RIGHT OF FIRST OFFER: SALE OF PROPERTY (a) After the expiration of the Tax Protection Period, Managing Member shall, prior to the exercise of its right to cause a Property Transfer as set forth in SECTION 10.1(a), give written notice (the "SALE NOTICE") to the Ceppeto Members (1) stating Managing Member's intention to cause such Property Transfer at a specified price (the "STATED PRICE") and (2) offering to sell, and to cause the Boston Properties Members to 51 sell, their entire Equity Interests in the Company (the "ENTIRE BP INTEREST") to the Ceppeto Members at a price calculated in accordance with SECTION 10.1A(c) and on all other relevant terms and conditions. The Sale Notice shall include a non-binding calculation of the amount which would be distributable to the Ceppeto Members in the event of a sale of the Property or such Property Transfer at the Stated Price, which calculation shall be determined in good faith by the Managing Member. (b) If Managing Member has forwarded a copy of the Sale Notice to the Ceppeto Members, the Ceppeto Members shall, within thirty (30) days after receiving a copy of the Sale Notice, elect one of the following options: (1) notify Managing Member of the Ceppeto Members election not to purchase the Entire BP Interest for the price determined under SECTION 10.1A(c), in which event and at which time Managing Member may cause the Company to market and sell the Property, provided that the price obtained for the Property is at least ninety-four percent (94%) of the Stated Price and a letter of interest (or similar statement) to acquire the Property is executed within six (6) months of Managing Member's receipt of the Ceppeto Member's election or deemed election pursuant to item (2) below not to purchase the Entire BP Interest and such letter (or similar statement) provides for a closing within a commercially reasonable time and such closing is consummated within such time period on terms which are, in all material respects, no less favorable to the Company as those specified in the letter of interest (or similar statement); or (2) notify Managing Member of the Ceppeto Member's election to purchase the Entire BP Interest for the price determined under SECTION 10.1A(c) on the same terms and conditions contained in the Sale Notice. Such notification shall be accompanied by a deposit in an amount equal to five percent (5%) of the amount payable to Managing Member pursuant to this SECTION 10.1A(b)(2) (such amount, together with any interest earned thereon, the "OTHER MEMBER'S SALE DEPOSIT"), which shall be refundable until the date which is the earlier of (i) thirty (30) days after the notification, or (ii) execution of a purchase and sale agreement on terms and conditions substantially the same as those contained in the Sale Notice, with such changes as the parties may agree upon. Notice of election to purchase shall be addressed to Managing Member and shall set forth the place of closing which, unless the Members shall otherwise agree, shall be at the office of the Company (or the offices of the Ceppeto Members' lender located in New York City), during usual business hours within ninety (90) days after the date of the giving of the notice of election to Managing Member. The Other Member's Sale Deposit shall be credited against the total purchase price for the Entire BP Interest being purchased pursuant to this SECTION 10.1A(b); PROVIDED, HOWEVER, that, if the closing shall fail to occur for any reason other than a default by the Boston Properties Members, subject to the provisions of this SECTION 10.1A(b)(2) above concerning refundability of the deposit, Managing Member shall have the 52 right to retain the Other Member's Sale Deposit as liquidated damages, it being agreed that in such instance Managing Member's actual damages would be difficult, if not impossible, to ascertain. If the Ceppeto Members shall not have given written notice to Managing Member of its election to purchase the Entire BP Interest within the thirty (30) day notice period, the Ceppeto Members shall be deemed to have exercised the option provided in subsection (1) above. (c) The value of the Entire BP Interest with respect to this SECTION 10.1A is the amount that the Boston Properties Members, collectively, would receive in liquidation of the Company's interest in the Property if (1) the Property were sold for the Stated Price, and the debts and other obligations of the Company secured by or otherwise incurred as to the Property (including the Senior Loan) are paid (including any prepayment penalties and other fees resulting from such prepayment), less the sum of all applicable transfer taxes incurred as a result of such sale, and an amount equal to three percent (3%) of such Stated Price, which the Members hereby unconditionally and irrevocably agree is a reasonable estimate and approximation of customary closing costs associated with similar transactions (provided however, that in consideration of the agreed upon reduction of such Stated Price by the amount of the transfer taxes which would be incurred in connection with a sale of the Property for such amount, the Ceppeto Members agree to pay any transfer taxes actually payable in connection with the conveyance contemplated hereunder, and shall indemnify the Boston Properties Members from and against any cost or expense resulting from the failure to pay such amounts as and when due), and (2) the proceeds of such hypothetical sale and any cash balances and/or reserves of the Company properly attributable to such Property were distributed in accordance with SECTION 9.3(b) or SECTION 9.4(b). (d) In connection with the sale of the Entire BP Interest to the Ceppeto Members pursuant to this SECTION 10.1A, the provisions of SECTION 10.8 and SCHEDULE 10.7(e) shall be applicable to such sale (acknowledging, however, that the Boston Properties Members are the transferring Members). (e) If the contemplated Property Transfer, or the conveyance of the Entire BP Interest, is not consummated pursuant to the provisions of this SECTION 10.1A, all the provisions of this SECTION 10.1A shall apply to any subsequent proposed Property Transfers. (f) The Management Agreement shall be terminated, at no cost to the Company or the Ceppeto Members, upon the closing of any transfer of the Entire BP Interest to the Ceppeto Members. 10.2. TRANSFER OF INTERESTS. (a) Except as otherwise specifically provided in this ARTICLE 10, no Member, and no direct or indirect beneficial owner of any Ceppeto Member, may, directly or indirectly, by operation of law or otherwise, sell, assign, gift, convey or otherwise 53 transfer all or any part of its Equity Interest (an "EQUITY TRANSFER"), including without limitation, any profits interest, rights to receive distributions, or other similar or dissimilar right or interest, without complying with the right of first offer procedures in SECTION 10.3. Any purported Equity Transfer not otherwise specifically permitted by this ARTICLE 10 shall be null and void and of no effect whatsoever. Notwithstanding the foregoing, (x) BPLP or any wholly-owned subsidiary of BPLP which is a disregarded entity for Federal income tax purposes, shall own at least one percent (1%) of the Percentage Interests which are represented by Class A Common Equity at all times prior to the expiration of the Tax Protection Period and (y) BP Member II (and BPLP, as applicable) may not cause or suffer to occur an Equity Transfer that is a direct transfer (or an indirect transfer through the sale or other conveyance of the equity interests in BP Member II (or such other disregarded person as may from time to time hold the Contributed Preferred Units) held directly or indirectly by BPLP) of all or any part of its Contributed Preferred Units in the Company (or any Exchange Property as defined in the Tax Protection Agreement) at any time prior to the expiration of the Tax Protection Period (1) without the consent of the Ceppeto Members, which consent may be withheld in the Ceppeto Members' sole and absolute discretion, or (2) unless no Built-In Gain (as defined in the Tax Protection Agreement) would be incurred by the Ceppeto Members as a result of such transfer. Anytime after the expiration of the Tax Protection Period, BPLP and/or BP Member II may cause or suffer to occur an Equity Transfer that is a direct transfer (or an indirect transfer through the sale or other conveyance of the direct or indirect equity interest in BP Member II held by BPLP) of all or any part of its Preferred Equity in the Company, PROVIDED that it first complies with SECTION 10.3. Any of BP Member, BP Member III and/or BPLP (and any other subsidiaries of BPLP who own a direct or indirect interest in each of BP Member and BP Member III), may cause or suffer to occur an Equity Transfer of all or any part of their respective direct or indirect Equity Interest in the Company (other than the direct or indirect interest of BPLP in BP Member II (or such other disregarded person as may from time to time hold the Contributed Preferred Units), which is subject to the third and fourth sentences of this SECTION 10.2(a)), provided that they first comply with SECTION 10.3. Notwithstanding anything to the contrary contained herein, in no event shall the terms of this SECTION 10.2 apply to any distributions to the Boston Properties Members in repayment of Preferred Equity pursuant to SECTION 9.3 or SECTION 9.4. In the event that BP Member II breaches its obligations as set forth in this SECTION 10.2(a), and such breach causes any of the Ceppeto Indemnified Parties (as defined in the Tax Protection Agreement) to incur Built-In Gain as provided above, the provisions of Section 8(a) of the Tax Protection Agreement shall apply as the sole and exclusive remedy of the Ceppeto Members (and the Ceppeto Indemnified Parties, as applicable) with respect to such breach. (b) Notwithstanding anything to the contrary contained in this Agreement, the following shall be permitted transfers (each, "PERMITTED EQUITY TRANSFERS"), which shall not be subject to the provisions of this ARTICLE 10 (except only the limitations, prior to the expiration of the Tax Protection Period, if any, (i) on transfers of equity interests in BP Member II and/or (ii) an Equity Transfer by BP Member II, as and to the extent set forth in SECTION 10.2(a)): (1) (A) BP Member and/or BP Member II and/or BP Member 54 III may sell, assign, gift, convey or otherwise transfer all or any portion of its Equity Interest to an Affiliate at any time and from time to time, (B) Boston Properties, Inc., a Delaware corporation ("BOSTON PROPERTIES"), and/or BPLP may engage in any merger, consolidation or other combination with or into another Person, or sell all or substantially all of its assets, or effect any reclassification, recapitalization or change in the terms of outstanding equity, or undertake any other change in control transaction, (C) Boston Properties and/or BPLP may admit any new equity interest holder or assign or issue to any Person any kind of interest whatsoever in Boston Properties and/or BPLP, (D) Boston Properties and/or BPLP may issue, sell, assign, gift, pledge, hypothecate or encumber any interest in Boston Properties and/or BPLP or any instruments convertible into or exchangeable for any interest in Boston Properties and/or BPLP and Boston Properties and/or BPLP may the transfer any right to vote any equity interest in Boston Properties and/or BPLP and (E) Boston Properties and/or BPLP may, directly or indirectly, sell, assign, gift, convey or otherwise transfer all or any portion of its beneficial ownership interest in BP Member and/or BP Member II and/or BP Member III to an Affiliate or, subject to compliance with SECTION 10.3, to an Institutional Holder at any time and from time to time, and (2) any Ceppeto Member and any direct or indirect beneficial owner of any Ceppeto Member shall have the right, from time to time and at any time (but subject in all events to the pledge of the Ceppeto Members' Equity Interest to the Company or the Boston Properties Members and their Affiliates pursuant to SECTION 13.5) to directly or indirectly sell, assign, gift, convey or otherwise transfer all or any of its Equity Interest to one (1) or more immediate family members of Richard Hadar and/or Eric Hadar or any trust for the benefit of Richard Hadar and/or Eric Hadar and/or any of their immediate family members. For all purposes under this Agreement, the term "immediate family member" shall mean any children, grandchildren, parents, grandparents, spouse and siblings of the applicable person, or any entity owned, directly or indirectly, solely by any one or more of such parties. (c) The Ceppeto Members and holders of direct or indirect beneficial interests in the Ceppeto Members may sell, assign, gift, convey or otherwise transfer all or any portion of their Class B Common Equity, PROVIDED that (1) they first comply with the provisions of SECTION 10.3 and (2) in no event shall the Ceppeto Members or any direct or indirect beneficial owner of the Ceppeto Members sell, assign, gift, convey or otherwise transfer any partial rights in and to their Class B Common Equity, including without limitation, any profits interest, rights to receive distributions, or other similar or dissimilar right or interest. Notwithstanding the foregoing, this SECTION 10.2(c) shall not apply to (A) Permitted Equity Transfers, or (B) pledges of the Ceppeto Members' equity in the Company pursuant to SECTION 10.6, that are made after the full and unconditional release of the pledge made by the Ceppeto Members to the Company or the Boston Properties Members and their Affiliates under SECTION 13.5. The Ceppeto Members, for themselves and on behalf of all direct and indirect beneficial owners of the Ceppeto Members, hereby acknowledge and agree that the identity of the holders of all direct and indirect beneficial interests in each of the Ceppeto Members is of material importance to each of the Boston Properties Members in agreeing to enter into this Agreement (and, specifically, in agreeing to the terms and restrictions contained in this ARTICLE 10) and to 55 perform the transactions contemplated hereby and by the Transaction Documents. The Ceppeto Members represent and warrant that SCHEDULE 5.6(b) and SCHEDULE 5.6(c) contain true and correct lists of all direct and indirect beneficial owners of the Ceppeto Members, and any direct or indirect transfer (as provided herein) of all or any portion of the interests held by such beneficial owners will be subject to SECTION 10.3. 10.3. RIGHT OF FIRST OFFER: INTERESTS. (a) Either the Ceppeto Members (acting collectively) or the Boston Properties Members (acting collectively), or their direct and indirect beneficial owners (as and to the extent applicable) (each, an "INITIATING MEMBER") may, at any time and from time to time only in accordance with SECTION 10.2 of this Agreement, deliver a written notice (a "FIRST OFFER NOTICE") to the other Member (the "RESPONDING MEMBER") stating a gross cash purchase price (the "OFFERED PRICE") at which the Initiating Member is prepared to sell all or a specified portion of its Equity Interest (or the direct or indirect interests therein, as applicable)(such Initiating Member's "OFFERED INTEREST") to one or more third parties. The Responding Member may elect to purchase the Offered Interest from the Initiating Member upon the terms and conditions set forth in the First Offer Notice by (1) giving written notice thereof to the Initiating Member and (2) depositing with an escrow agent reasonably acceptable to the Initiating Member an amount equal to 5% of the Offered Price (the "OFFERED PRICE DEPOSIT"), each within thirty (30) days after the receipt of a First Offer Notice (the "RESPONSE PERIOD"). (b) If the Responding Member elects to purchase the Offered Interest, the Responding Member shall be obligated to purchase the Offered Interest without any reserve or adjustment for any contingent liabilities of the Company; PROVIDED, however, if the Boston Properties Members, collectively, are the Responding Member, the Responding Member shall be entitled to reserve or adjust in its reasonable discretion for any potential liability or obligation of the Ceppeto Members pursuant to SECTION 13.5. Any such reserves shall be retained by the BP Member as collateral for the Ceppeto Indemnitors' indemnification obligations under SECTION 13.5 and shall be maintained in an interest-bearing account (all such interest to be retained in such account, and to be earned for the benefit of the Ceppeto Members) at a commercial bank, trust company, savings bank or other similar institutions selected by the BP Member and reasonably acceptable to the Ceppeto Members. Any and all risk of loss with respect to such account shall be borne solely and exclusively by the Ceppeto Members. All amounts contained in such account will be remitted to the Ceppeto Members if, as and when the pledge of the Ceppeto Members' Equity Interest would have been released pursuant to SECTION 13.5(e)(3). Nothing contained in this SECTION 10.3(b) shall limit or otherwise affect the Ceppeto Indemnitors' indemnification obligations contained in SECTION 13.5. In addition, if the Initiating Member has incurred recourse obligations (including any guaranty) with respect to any Company financing (including the Senior Loan), the obligation of the Initiating Member to convey the Offered Interest shall be conditioned on the Responding Member either (1) paying in full all amounts owing to the lender with respect to such financing, (2) obtaining from such lender a full and unconditional release of any recourse 56 obligations of the Initiating Member, except for amounts payable under any environmental indemnities and customary carve-outs or exceptions for commercial non-recourse loans, or (3) providing an indemnification with respect to such recourse obligations in form and substance reasonably acceptable to the Initiating Member. (c) The closing on any sale of an Offered Interest to a Responding Member pursuant to this SECTION 10.3 shall be held on the date which is ninety (90) days following the date on which the Responding Member delivered the notice described in clause (1) of SECTION 10.3(a), or at such earlier date as the Responding Member may specify on at least three (3) days prior written notice to the Initiating Member (in either event, the "CLOSING DATE"). The closing shall be held at the office of the Company (or the office of the Ceppeto Members' lender located in New York City) or at such other location as may be mutually acceptable to the Initiating Member and the Responding Member. On the Closing Date, the purchase price shall be paid in cash by wire transfer of immediately available federal funds (and the amount of the Offered Price Deposit pursuant to SECTION 10.3(a) shall be released to the Initiating Member in partial satisfaction of the purchase price), PROVIDED, HOWEVER, that if the closing shall fail to occur on the Closing Date for any reason other than a default by the Initiating Member, then the Initiating Member shall be entitled to retain the Offered Price Deposit as liquidated damages, it being agreed that in such instance the Initiating Member's actual damages would be difficult, if not impossible, to ascertain. Such purchase price shall equal the Offered Price less an amount equal to the sum of all applicable transfer taxes incurred as a result of such sale plus three percent (3%) of the Offered Price, which the parties hereto unconditionally agree is a reasonable estimate and approximation of customary closing costs which would be associated with similar transactions (provided however, that in consideration of the agreed upon reduction of such Offered Price by the amount of the transfer taxes which would be incurred in connection with a sale of the Property for such amount, the Responding Member agrees to pay any transfer taxes actually payable in connection with the conveyance contemplated hereunder, and shall indemnify the Initiating Member from and against any cost or expense resulting from the failure to pay such amounts as and when due). The Initiating Member shall assign its Offered Interest to the Responding Member free and clear of any and all claims, liens, pledges, options, restrictive covenants, charges, hypothecations, preferences, priorities, security interests or other encumbrances of any kind or nature, and shall provide customary representations and indemnifications in connection therewith. (d) If the Responding Member fails to elect to purchase within the Response Period or fails to close the transaction on the designated Closing Date for any reason other than a default by the Initiating Member, the Initiating Member may, without the further consent of the Responding Member, sell its Offered Interest to a third party reasonably acceptable to the Responding Member (a "THIRD-PARTY BUYER"), PROVIDED that: (1) the terms and conditions of such sale (including without limitation, representations, warranties, covenants, guaranties, indemnities, agreements and side agreements) shall be no more favorable (in any material manner) to such Third-Party Buyer than those contained in the First Offer Notice; (2) such sale or assignment shall be 57 consummated by no later than the date which is six (6) months (the "SALES PERIOD") after the earlier of (x) in the case of a failure to elect to purchase, the end of the Response Period, or (y) in the case of the Responding Member's failure to close, the date that was to be the Closing Date; (3) the purchase price shall be paid in cash or immediately available funds on the closing date of such conveyance; and (4) the Third-Party Buyer shall be a Qualified Buyer. For purposes hereof, a "QUALIFIED BUYER" shall mean any entity (w) that has not been and whose principals have not been convicted or charged with a felony and is otherwise of good moral character and reputation, (x) if the Responding Member is the Boston Properties Members, collectively, that is not a Competitor of the Company, the Responding Member or any of their respective Affiliates, (y) if the Responding Member is the Ceppeto Members, that expressly assumes all of the Boston Properties Members' and BPLP's, as the case may be, covenants and other obligations hereunder and under the Tax Protection Agreement with respect to the restrictions on sale and the maintenance of certain indebtedness to be guaranteed by the Ceppeto Members, prior to the expiration of the Tax Protection Period, and (z) is otherwise reasonably acceptable to the Responding Member. The Initiating Member shall promptly and diligently provide the Responding Member with all information and materials reasonably necessary or otherwise requested by Responding Member so as to permit to Responding Member to determine whether or not the Third-Party Buyer is a Qualified Buyer. (e) Upon the assignment of the Offered Interest to the Third-Party Buyer in compliance with this SECTION 10.3, the Third-Party Buyer shall be admitted as a member of the Company in place of, or (if less than the entire interest of the Initiating Member is assigned) in addition to, the Initiating Member. As a condition precedent to the foregoing, the Third-Party Buyer shall execute and deliver an instrument, in substance and form satisfactory to the Responding Member, assuming and agreeing to perform the terms and conditions of this Agreement as provided in SECTION 10.4 (and if the Responding Member is the Ceppeto Members, the Boston Properties Members' and BPLP's, as the case may be, covenants and other obligations hereunder and under the Tax Protection Agreement with respect to the restrictions on sale and the maintenance of certain indebtedness to be guaranteed by the Ceppeto Members, prior to the expiration of the Tax Protection Period), and such other documents as the Responding Member may reasonably require in order to effectuate the foregoing. If the Third-Party Buyer is not a Qualified Buyer, then the Initiating Member shall retain its Offered Interest and shall not proceed with its sale to the Third-Party Buyer. (f) During the Sales Period, the Initiating Member may require the Company to incur reasonable and customary expenses in connection with the marketing of the Offered Interest, such as the preparation of studies and brochures and legal fees to prepare and negotiate agreements, and all such expenses shall be reimbursed promptly by the Initiating Member. 58 (g) The Managing Member shall, when directed by either the Initiating or the Responding Member, exercise reasonable efforts to enter into any arrangement and take any action that such Member is entitled to require pursuant to this SECTION 10.3. (h) At the request of the Responding Member, the purchase and sale of the Offered Interest, whether to the Responding Member or to a Third-Party Buyer, will be structured, if possible, to avoid a termination of the Company for Federal tax purposes and/or under the Act; PROVIDED that such structure does not adversely impact the Initiating Member or the contemplated transfer. (i) If a transaction pursuant to this SECTION 10.3 results in the Ceppeto Members acquiring the Entire BP Interest, then the Management Agreement shall be terminated, at no cost to the Company or the Ceppeto Members, upon the closing of such transaction. (j) Whether or not any transaction contemplated by the foregoing provisions of this SECTION 10.3 is consummated pursuant to the provisions of any First Offer Notice, compliance with all of the provisions of this SECTION 10.3 will be required in connection with any subsequent Equity Transfer previously proposed but not consummated within the applicable Sales Period and any subsequently proposed Equity Transfer (other than a Permitted Equity Transfer) in accordance with SECTION 10.2. 10.4. ASSUMPTION BY ASSIGNEE. (a) Any assignment of a Member's Equity Interest permitted under this ARTICLE 10 shall be in writing, and shall be an assignment and transfer of all of the assignor's rights and obligations hereunder with respect to such Equity Interest, and the assignee shall expressly agree in writing to be bound by all of the terms of this Agreement (and if the Ceppeto Members will continue to be Members following such assignment, the Boston Properties Members' and BPLP's, as the case may be, covenants and other obligations hereunder and under the Tax Protection Agreement with respect to the restrictions on sale and the maintenance of certain indebtedness to be guaranteed by the Ceppeto Members, prior to the expiration of the Tax Protection Period), and assume and agree to perform all of the assignor's agreements and obligations existing or arising at the time of and subsequent to such assignment with respect to such Equity Interest. Upon any such permitted assignment of the assignor's Equity Interest, and after such assumption, the assignor shall be relieved of its agreements and obligations hereunder with respect to such Equity Interest arising after such assignment and the assignee shall become a Member in place of the assignor with respect to such Equity Interest. An executed counterpart of each such assignment of an Equity Interest and assumption of a Member's obligations shall be delivered to each Member and to the Company. The assignee shall pay all expenses incurred by the Company in admitting the assignee as a Member. Except as otherwise expressly provided herein, no permitted assignment shall terminate the Company. 59 (b) As a condition to any assignment of a Member's Equity Interest, the selling Member shall obtain such consents as may be required from third parties, if any, or waivers of such consent requirements. The other Members shall use reasonable efforts to cooperate with the selling Member in obtaining such consents or waivers, provided, however, that in no event shall the other Members be required to incur or assume any cost or obligation, divest any asset or make any financial accommodation of any kind in connection therewith. 10.5. AMENDMENT OF CERTIFICATE OF FORMATION. If an assignment of a Member's Equity Interest shall take place pursuant to the provisions of this ARTICLE 10, then the continuing Members promptly thereafter shall cause to be filed, to the extent necessary, an amendment to the Company's Certificate of Formation with all applicable state authorities, together with any necessary amendments to the fictitious or assumed name(s) of the Company in order to reflect such change or take such similar action as may be required. 10.6. PLEDGING OF INTERESTS. The Ceppeto Members, and any permitted assignee of their Equity Interest, may pledge, hypothecate or otherwise encumber all or any part of such Equity Interests as security for any financing provided to the Ceppeto Members or their Affiliates by an institutional lender and in form and substance reasonably satisfactory to the Managing Member; PROVIDED that (a) such financing may be obtained and such pledge, hypothecation or encumbrance may be made, only in the event that and for so long as no part of the Ceppeto Members' Equity Interest is then pledged to the Company, the Boston Properties Members or any of their Affiliates pursuant to SECTION 13.5, (b) the pledge shall be limited solely to the right to receive distributions and/or other proceeds of the Equity Interest and (c) such financing institution agrees in writing, in form and substance reasonably acceptable to the Managing Member, that if, as a result of a default under any such financing, a party other than Ceppeto or Ceppeto Holdings (each as currently constituted) acquires, succeeds to ownership of, or gains any rights in any part or all of the Ceppeto Members' Equity Interest in the Company, such party's interest in the Company shall be subject to the terms and conditions of this Agreement, in no event shall the holder of such Equity Interest be entitled to be admitted to the Company as a Member and the Managing Member shall continue to have exclusive authority to act for and make decisions on behalf of the Company as and to the extent set forth in this Agreement. The Boston Properties Members and any permitted assignees of their respective Equity Interests, may pledge, hypothecate or otherwise encumber all or any part of such Equity Interests at any time and from time to time in its discretion. 10.7. CONVERSION RIGHTS. (a) Subject to the terms and conditions set forth herein, (1) at any time after expiration of the Tax Protection Period, the Ceppeto Members (acting collectively) or (2) at any time after the twenty-fifth (25th) anniversary of the Effective Date, the BP Member, shall have the right (either such right, the "CONVERSION RIGHT") to require the conveyance to the BP Member by the Ceppeto Members of the Ceppeto Members' collective entire Equity Interest (the "ENTIRE INTEREST") in consideration of the value of said Entire Interest as determined by the procedures set forth in this SECTION 10.7(a) 60 (whichever of the BP Member or the Ceppeto Members as shall exercise the Conversion Right for the purposes of this SECTION 10.7, the "EXERCISING MEMBER"). The consideration to be paid to the Ceppeto Members for the Ceppeto Members' Entire Interest shall be, at the option of the Ceppeto Members, exercised as provided in SECTION 10.7(c), paid in cash and/or OP Units. The value of the OP Units shall be determined in the manner set forth in SECTION 10.7(c) below. If the Ceppeto Members receive OP Units pursuant to this SECTION 10.7, the Managing Member shall cause Boston Properties to enter into a Registration Rights Agreement for the benefit of the Ceppeto Members in substantially the form attached hereto as EXHIBIT 10.7. The Conversion Right shall be exercised by delivery of a written notice (the "EXERCISE NOTICE") from the Exercising Member to the other Member(s) (the "NON-EXERCISING MEMBER"). Upon the exercise of a Conversion Right, the value of the Ceppeto Members' Entire Interest shall be determined in accordance with SCHEDULE 10.7(a) - "APPRAISAL" attached hereto (such procedure and determination of value, the "APPRAISAL"). The date on which the value is determined by the Appraisal is herein referred to as the "DETERMINATION DATE." (b) Notwithstanding anything to the contrary provided in SECTION 10.7(a), the Non-Exercising Member may delay the effective date of the Exercise Notice, and thus the commencement of the Appraisal, once, for not more than six (6) months from the date of the Exercise Notice, by written notice (the "DELAY NOTICE") to the Exercising Member sent within twenty (20) Business Days after receipt of the Exercise Notice, such Delay Notice to specify the period of delay requested (but, regardless of the period of delay requested, the Non-Exercising Member shall have no additional right to delay the commencement of the Appraisal, the only right being a one-time right to delay the commencement of the Appraisal for no longer than six (6) months from the date of the Exercise Notice). In the event a Delay Notice is given, the date of the Exercise Notice shall be deemed to be the date within such six (6) month period as specified in the Delay Notice. (c) No later than the date which is ten (10) days prior to the Original Delivery Date, the Ceppeto Members shall elect by written notice to the BP Member whether payment under this SECTION 10.7 shall be in cash or OP Units or a combination of cash and OP Units (subject, with respect to such election as to OP Units, to the rights of the BP Member as set forth in this SECTION 10.7(c)). If the Ceppeto Members fail to timely make the election contemplated by this SECTION 10.7(c), the BP Member shall be entitled to make such payment in cash and/or OP Units, as determined by the BP Member (and subject to the rights of the BP Member as set forth in this SECTION 10.7(c)). Notwithstanding anything to the contrary contained in this SECTION 10.7, in the event that the Ceppeto Members elect to receive (or the BP Member elects to pay) all or a portion of the payment in cash pursuant to this SECTION 10.7(c), the BP Member shall have the right at its option to pay a portion of the applicable amount (but not less than fifty percent (50%) of the applicable amount) in cash on the Actual Delivery Date and the balance through the delivery by BPLP of an unsecured promissory note for the remaining amount (provided that, at BP Member's option, BP Member may deliver such promissory note, together with a guaranty of BPLP with respect to BP Member's obligations thereunder), 61 such note to be due in full on the first anniversary of such Actual Delivery Date and to bear interest at a rate equal to seven and one-half percent (7 1/2%) per annum (except that the BP Member or BPLP, as applicable, shall have the right to prepay such promissory note, in whole or in part, at any time with no premium or penalty). If the Ceppeto Members elect to receive payment in OP Units (or the BP Member elects to pay OP Units) pursuant to this SECTION 10.7(c), the Ceppeto Members will be admitted as Additional Limited Partners (as defined in the Partnership Agreement) of BPLP (effective as of the Actual Delivery Date), and BPLP will issue to the Ceppeto Members OP Units and corresponding Partnership Interests (as defined in the Partnership Agreement). The number of OP Units to be issued to the Ceppeto Members pursuant to this SECTION 10.7(c) (the "UNIT NUMBER") shall be equal to the quotient of (1) the value of the Ceppeto Members' Entire Interest determined in accordance with SCHEDULE 10.7(a), LESS the amount, if any, to be paid to the Ceppeto Members in cash or by delivery of such unsecured promissory note, DIVIDED BY (2) the Fair Market Value of One OP Unit. In the event that the Ceppeto Members elect to receive OP Units (or the BP Member elects to pay OP Units), the BP Member may postpone or adjourn, on one or more occasions, the date of closing of the Conversion Right (the "ACTUAL DELIVERY DATE") (including the Original Delivery Date) for a period not to exceed in the aggregate one year from the Original Delivery Date. If the Actual Delivery Date is so postponed, the Members hereby acknowledge that: (i) the Unit Number shall be determined based on the Fair Market Value of One OP Unit determined on the Actual Delivery Date, PROVIDED that, in such case, the Ceppeto Members shall also be entitled to receive an amount equal to any distributions that they otherwise would have been entitled to receive as holders of such OP Units for the period from the Original Delivery Date to the Actual Delivery Date; (ii) the Ceppeto Members shall be entitled to receive interest on the portion of the payment which is to be paid in cash, to the extent not paid in cash or by delivery of a promissory note on the Original Delivery Date, at a rate of seven and one-half percent (71/2%) per annum for the period from the Original Delivery Date to the date so paid in cash or by delivery of the promissory note; and (iii) the value of the Ceppeto Members' Entire Interest determined in accordance with this SECTION 10.7 shall remain fixed as of and after the Determination Date until the Actual Delivery Date, and in no event shall the Ceppeto Members be entitled to any distributions in consideration of such Entire Interest pursuant to this Agreement after the Original Delivery Date. (d) Subject to the BP Member's right to postpone or adjourn the Actual Delivery Date pursuant to SECTION 10.7(c), the BP Member shall designate a closing date on not less than ten (10) Business Days prior written notice to the Ceppeto Members for the conveyance of the Ceppeto Members' Entire Interest required pursuant to this SECTION 10.7 (such initially scheduled closing date, the "ORIGINAL DELIVERY DATE" with the actual closing date being the Actual Delivery Date (which shall be the Original Delivery Date if the Original Delivery Date is not adjourned or postponed by the BP Member as provided in SECTION 10.7(c) above)), which Original Delivery Date shall be not less than fifteen (15) nor more than ninety (90) Business Days after the Determination Date. On the Actual Delivery Date, in exchange for the Ceppeto Members' Entire Interest, the BP Member shall, as the case may be: (i) cause the applicable number of OP Units to be 62 issued to the Ceppeto Members or (ii) pay to the Ceppeto Members the applicable amount in cash (together with the promissory note, if applicable), each as provided in SECTION 10.7(c), PROVIDED, HOWEVER, that in lieu of any fractional OP Units resulting from such calculation, the BP Member shall pay in cash the value attributable to such fractional OP Unit. (e) Any transfer of the Ceppeto Members' Entire Interest to the BP Member or its designee pursuant to this SECTION 10.7 shall, in addition to any other provisions of this ARTICLE 10, be subject to the provisions of SCHEDULE 10.7(e) - "PURCHASING DOCUMENTS: CLOSING MATTERS". (f) If and to the extent OP Units cannot be issued to the Ceppeto Members pursuant to this SECTION 10.7 upon the exercise of a Conversion Right without violating (based upon the reasonable determination of the BP Member, with the advice of counsel) any applicable federal or state securities laws or the HSR Act or due to the inability of the Ceppeto Members to provide the information and representations referred to or contained in this SECTION 10.7(f), the consideration not so paid in OP Units shall be paid by the BP Member to the Ceppeto Members in cash pursuant to SECTION 10.7(c) (subject to the BP Member's right to deliver up to fifty percent (50%) of such amount in the form of an unsecured promissory note made or guaranteed by BPLP as provided in SECTION 10.7(c)), subject to the BP Member's right to waive the information and representation requirements of this SECTION 10.7(f). In determining if OP Units can be provided as consideration pursuant to the exercise of any Conversion Right, the BP Member may require that the Ceppeto Members submit to BPLP such information, certification or affidavit (including representations and warranties) as the BP Member may reasonably require in connection with determining compliance with any applicable federal or state securities laws or the HSR Act. The Ceppeto Members shall use reasonable efforts to respond promptly to such requests for such written representations or other instruments as are necessary or appropriate, in BP Member's reasonable judgment, to effect compliance with applicable law. Nothing contained in this Agreement shall be deemed to limit the right of the BP Member, BPLP or Boston Properties to modify, restate or otherwise amend their respective Organizational Documents. (g) With respect to any OP Units issued to the Ceppeto Members pursuant to this SECTION 10.7 (the "ISSUED OP UNITS"), the Ceppeto Members shall receive a pro rata distribution for the portion of the fiscal quarter in which the Actual Delivery Date occurs (the "CLOSING QUARTER") commencing on the Actual Delivery Date and ending on the last day of the Closing Quarter on all outstanding Issued OP Units held by the Ceppeto Members on the record date for dividends declared on the BXP Stock for the Closing Quarter. 63 10.8. PROVISIONS GENERALLY APPLICABLE TO SALES. For purposes of this SECTION 10.8, the Ceppeto Members shall be treated as a single Member and the Boston Properties Members shall be treated as a single Member. The following provisions shall be applicable to sales under SECTIONS 10.1A, 10.3, 10.7 and 12.2: (a) At the closing of the sale of all or a portion of the Equity Interest of a Member to the other Member, the selling Member shall execute an assignment of its interest in the Company, free and clear of all liens, encumbrances and adverse claims, which assignment shall be in form and substance reasonably satisfactory to the purchasing Member, and such other instruments as the purchasing Member shall reasonably require to assign all or such portion of the Equity Interest of the selling Member to such Person as the purchasing Member may designate. For any sale or transfer of all or a portion of a Member's Equity Interest under this ARTICLE 10, the purchasing Member may designate the assignee of such Equity Interest, which assignee (i) in connection with the sale of transfer of a Member's Entire Interest, need not be an Affiliate of the purchasing Member and (ii) in connection with the sale of transfer of less than all of a Member's Entire Interest, shall be an Affiliate of the purchasing Member. (b) It is the intent of the parties to this Agreement that the requirements or obligations, if any, of one Member to sell all or a portion of its Equity Interest to the other Member shall be enforceable by an action for specific performance of a contract relating to the purchase of real property or an interest therein. In the event that the selling Member shall have created or suffered any unauthorized liens, encumbrances or other adverse interests against either the Property or the selling Member's interest in the Company, the purchasing Member shall be entitled either to an action for specific performance to compel the selling Member to have such defects removed, in which case the closing shall be adjourned for such purpose, or, at the purchasing Member's option, to an appropriate offset against the purchase price, which offset shall include all reasonable costs associated with enforcement of this Section. (c) At the election of the purchasing Member, the purchase and sale of all or a portion of an Equity Interest will be structured to avoid, if possible, a termination of the Company for Federal tax purposes and/or under the Act, providing that such structure does not adversely impact the selling Member or the contemplated transfer. (d) At the request of the Ceppeto Members, any purchase and sale or other transfer of all or any portion of the Ceppeto Members' Entire Interest to the Managing Member in exchange for OP Units (or a combination of cash and OP Units) will, to the extent reasonably practicable, be structured in consideration of the tax consequences of such transfer to the Ceppeto Members, providing that such structure (i) does not adversely impact the Managing Member or its Affiliates, the Property or the contemplated transfer (all as determined by the Managing Member) and (ii) does not cause the Managing Member or its Affiliates, the Property or the contemplated transfer to incur any additional cost or other liability which is not paid in full by the Ceppeto Members on the date of such sale or other transfer. 64 (e) In connection with the sale or other transfer of the Entire BP Interest to the Ceppeto Members or their designee, the BP Member shall, at the Ceppeto Member's sole cost and expense, deliver originals or certified copies of all books and records and other material relating to the Property, and otherwise cooperate with the reasonable requests of the Ceppeto Members in connection with the transition of management of the Property to the Ceppeto Members or their designee.

An appropriate amendment to or cancellation of the Certificate of Formation and all other filings required by law shall be made in accordance with any action taken pursuant to this SECTION 11.3. ARTICLE 12. DISSOLUTION 12.1. WINDING UP. Upon dissolution of the Company by expiration of the term hereof, by operation of law, by any provision of this Agreement or by agreement between the Members, the Company's business shall be wound up and all its assets distributed in liquidation. In such dissolution, except as otherwise expressly provided in ARTICLE 11, the Managing Member shall be the Liquidating Member. If both Boston Properties Members are the subject of a dissolution or bankruptcy event described in ARTICLE 11, then Ceppeto, not Managing Member, will be the Liquidating Member. The Liquidating Member shall have the right to: 66 (a) wind up the Company and cause the Company's assets to be sold and the proceeds of sale distributed as provided in Section 12.5; or (b) notwithstanding anything to the contrary contained in this Agreement, cause the assets of the Company to be appraised and, at its option, purchase the Entire Interest of the other Member, all in accordance with SECTION 12.2. 12.2. PURCHASE OF NON-LIQUIDATING MEMBER'S INTEREST. (a) For purposes of this SECTION 12.2, the Ceppeto Members shall be treated as a single Member and the Boston Properties Members shall be treated as a single Member. The Liquidating Member, within thirty (30) days after the commencement of the dissolution of the Company, may give notice (the "APPRAISAL NOTICE") to the other Member electing to have the fair market value of the Company's assets determined by appraisal pursuant to SECTION 12.2(b) (the "FAIR MARKET VALUE"). The fees and expenses of such appraisers shall be borne by the Company. The Liquidating Member shall have the option, by notice given to the other Member within forty-five (45) days after receipt of the determination of Fair Market Value pursuant to SECTION 12.2(b), to purchase the other Member's Entire Interest at a price equal to the amount which would have been distributable to the other Member in accordance with the provisions of SECTION 9.3(b) or 9.4(b), as applicable, and SECTION 12.5 if all of the Company's assets had been sold for an amount equal to such Fair Market Value and any debts, liabilities and expenses which would have been paid by the Company or reserved against pursuant to SECTION 12.5 out of the proceeds of such sale were deducted in determining such Fair Market Value. If after the receipt of the determination of Fair Market Value pursuant to SECTION 12.2(b), the Liquidating Member elects not to exercise the option to purchase the other Member's Entire Interest pursuant to this SECTION 12.2(a), then the Liquidating Member shall have all of its rights under this ARTICLE 12 as if the Appraisal Notice had not been given. The provisions of SCHEDULE 10.7(e) and SECTION 10.8 shall apply to a purchase under this SECTION 12.2, except that any adjustments required pursuant to SECTION 10.8 shall be applicable to any events and/or liabilities or income which were not included in determining the Fair Market Value. (b) If the Fair Market Value of the assets of the Company is required to be determined for purposes of this SECTION 12.2, such Fair Market Value, if not otherwise agreed upon by the Members, shall be determined as set forth in this SECTION 12.2(b), and otherwise in accordance with SCHEDULE 10.7(a). All appraisers referred to herein shall be real estate appraisers which are members of the New York Chapter of the American Institute of Real Estate Appraisers for at least seven (7) years. Each Member shall select one (1) appraiser. In the event that either Member fails to select an appraiser within thirty (30) days after receipt of the Appraisal Notice, then such Member's appraiser shall be selected by the other Member from a list of no fewer than five (5) appraisers compiled and maintained by the Managing Member. After the selection, each appraiser shall independently determine the gross fair market value of the assets of the Company. If the separate appraisals differ, the Members shall have a period of ten (10) days after receipt 67 of the appraisals to agree on the Fair Market Value. In the event the Members cannot agree on the Fair Market Value in accordance with the preceding sentence, the two (2) appraisers referred to therein shall within ten (10) days after the expiration of the ten (10) day period described in the preceding sentence select a third appraiser. In the absence of such a selection, the third appraiser shall be selected by the New York Chapter of the American Institute of Real Estate Appraisers. The third appraiser shall decide which of the two (2) appraisals established by the appraisers in accordance with this SECTION 12.2(b) constitutes the Fair Market Value, and such decision shall be conclusive and binding on the parties. 12.3. OFFSET FOR DAMAGES. In the event of dissolution resulting from an event described in ARTICLE 11, the Liquidating Member shall be entitled to deduct from the amount payable to the other Member pursuant to SECTION 12.2, SECTION 12.4 or SECTION 12.5, the amount of damages, including reasonable attorneys' fees and disbursements, incurred by the Company or the Liquidating Member proximately resulting from any such event, as established by a court order. 12.4. DISTRIBUTIONS OF OPERATING CASH FLOW. Subject to SECTION 12.5 as to proceeds of liquidation, during the period of liquidation the Members shall continue to receive distributions of Operating Cash Flow and Capital Event Proceeds and to share profits and losses for all tax and other purposes as provided elsewhere in this Agreement. 12.5. DISTRIBUTIONS OF PROCEEDS OF LIQUIDATION. For purposes of this SECTION 12.5, "proceeds of liquidation" shall equal cash available for liquidation, net of liens secured by the Property, PROVIDED that neither the Company nor the Members shall be personally liable for, nor shall either or any of them be released from, such debts. The proceeds of liquidation shall be applied in the order of priority set forth in this SECTION 12.5. (a) FIRST. To the payment of: (1) debts and liabilities of the Company, and (2) expenses of liquidation. (b) SECOND. To the setting up of any reserves that the Liquidating Member may deem necessary for any contingent or unforeseen liabilities or obligations of the Company or of the Members arising out of or in connection with the Company. Such reserves may be deposited by the Company in a bank or trust company acceptable to the Liquidating Member to be held by it for the purpose of disbursing such reserves in payment of any of the aforementioned liabilities or obligations, and at the expiration of such period as the Liquidating Member shall deem advisable, distributing the balance, if any, pursuant to SECTION 12.5(c). (c) THIRD. Any balance remaining shall be distributed to the Members in accordance with SECTION 9.6(a). 68 12.6. ORDERLY LIQUIDATION. A reasonable time shall be allowed for the orderly liquidation of the assets of the Company and the discharge of liabilities to creditors so as to enable the Members to minimize the losses normally attendant upon a liquidation. 12.7. FINANCIAL STATEMENTS. During the period of winding up, the Company's then independent certified public accountants shall prepare and furnish to each of the Members, until complete liquidation is accomplished, all the financial statements provided for in SECTION 7.1. ARTICLE 13. MEMBERS 13.1. LIABILITY. A Member shall not be personally liable for the debts, liabilities or obligations of the Company or of any other Member except to the extent required under the Act. Notwithstanding the foregoing, a Member will be liable for any distributions made to it if, after such distribution, the outstanding liabilities of the Company (other than liabilities to Members on account of their interests in the Company and liabilities for which the recourse of creditors is limited to specific Company property) exceed the fair value of the Company's assets (PROVIDED that the fair value of Company property that secures recourse liability shall be included only to the extent its fair value exceeds such liability) and the Member had knowledge of this fact at the time the referenced distribution was received. 13.2. NO FIDUCIARY OBLIGATIONS. To the maximum extent permitted by applicable law, none of the Managing Member nor any other Members shall have any fiduciary duty or other duty (other than contractual obligations under this Agreement, the Master Transaction Agreement or the Tax Protection Agreement) to the other Members with respect to the business and affairs of the Company. To the extent that any such fiduciary duty or other duties are imposed on the Managing Member or any other Boston Properties Members or any Ceppeto Members under the Act, the Ceppeto Members hereby unconditionally and irrevocably waive the same and agree that neither the Managing Member nor any other Boston Properties Members shall have any liability for breach of such duties and the BP Members hereby unconditionally and irrevocably waive the same and agree that neither of the Ceppeto Members shall have any liability for breach of such duties. Each of the Members hereby covenant, as a material inducement to the Managing Member and the other Members to enter into this Agreement, that the Members shall not commence or join or otherwise bring or advance or participate in any claim against the Managing Member or any other Members based upon any purported breach of fiduciary duty or other duty (other than contractual obligations under this Agreement, the Master Transaction Agreement or the Tax Protection Agreement). 13.3. POWER OF ATTORNEY. The Ceppeto Members hereby irrevocably constitute and appoint the Managing Member, with full power of substitution, as their true and lawful attorney, which power shall be coupled with an interest, in their name, place and stead to sign, execute, acknowledge, swear to, deliver, record and file, as appropriate (collectively, the "Action") and in accordance with this Agreement, any and all certificates, documents and 69 instruments that in the discretion of the Managing Member are required to be signed, executed, acknowledged, sworn to, delivered, recorded or filed by such Member to discharge the purposes of the Company as set forth in this Agreement; PROVIDED that such action does not cause or result in the incurrence of any personal liability on the part of such Member hereunder. Prior to the taking of any Action pursuant to the power of attorney contained in this SECTION 13.3, the Managing Member shall give not less than (5) Business Days prior written notice to the Ceppeto Members, which notice is intended to provide the Ceppeto Members with the opportunity to take such Action in lieu of the Managing Member, PROVIDED HOWEVER, that nothing contained herein (including without limitation, any failure of the Managing Member to deliver such notice, or any refusal on the part of the Ceppeto Members to take such Action, or other action or notice given by the Ceppeto Members to the effect that such Action is not to be taken) shall limit or modify the power of attorney granted to the Managing Member herein. 13.4. CONSENT OF CEPPETO MEMBERS. Whenever the consent, approval, determination or decision of the Ceppeto Members is required under this Agreement, including to amend or waive any provisions of this Agreement, such consent, approval, determination or decision will be deemed given by, and binding upon, each Ceppeto Member if the Company obtains the written consent, approval or decision of Eric Hadar, and each of the Ceppeto Members hereby irrevocably agrees that Eric Hadar will have the power and authority to grant any such written consent or approval, or make any such determination or decision, on behalf of, and as the duly authorized agent and representative of, such Ceppeto Member. Each Ceppeto Member by execution and delivery of this Agreement irrevocably constitutes and appoints Eric Hadar as its true and lawful attorney-in-fact with full power and authority in such Ceppeto Member's name, place and stead to execute, acknowledge and deliver such certificates, instruments, documents and agreements as are necessary or appropriate to make any and all amendments or restatements of this Agreement. The appointment by each Ceppeto Member of Eric Hadar as attorney-in-fact is deemed to be a power coupled with an interest and will survive, and will not be affected by the subsequent bankruptcy, death, incapacity, disability, adjudication of incompetence or insanity, or dissolution of any Ceppeto Member hereby giving such power. It will be a condition to any transfer of a Ceppeto Member's interest in the Company that the foregoing power of attorney be granted by the transferee of such Ceppeto Member's interest. Notwithstanding the foregoing, in the event of (a) the death, incapacity, disability, adjudication of incompetence or insanity of Eric Hadar, or (b) the resignation by Eric Hadar as authorized agent and representative of the Ceppeto Members hereunder, such resignation to be effective not less than thirty (30) days after delivery of notice to the Company and the Managing Member, or (c) an election by the Ceppeto Members, acting jointly, to replace Eric Hadar as their agent and representative, a replacement authorized agent and representative hereunder shall be appointed by the Ceppeto Members, such person in all events to be reasonably acceptable to Managing Member. 13.5. INDEMNIFICATION OBLIGATIONS; PLEDGE OF CEPPETO MEMBERS' EQUITY INTEREST. 70 (a) CEPPETO INDEMNIFICATION OBLIGATION. From and after the Effective Date, Eric Hadar, Richard Hadar, Ceppeto and Ceppeto Holdings (collectively, the "CEPPETO INDEMNITORS") agree, jointly and severally, to indemnify, defend and hold harmless the BPLP Indemnified Parties from and against all Losses which are incurred or suffered by any one or more of them based upon, arising out of, in connection with or by reason of: (1) the breach by Richard Hadar, Eric Hadar, the Ceppeto Members or either of them of any of the representations and warranties of Richard Hadar, Eric Hadar, and/or the Ceppeto Members or either of them contained in this Agreement; and/or (2) Partnership Claims; and/or (3) any liability, obligation, claim, lien, cost, expense or encumbrance of any kind or nature (other than pursuant to the Purchase Contracts and those costs and expenses specifically set forth on the attached SCHEDULE 13.5(a)(3)), whether accrued, absolute, contingent or otherwise, asserted or unasserted, known or unknown, including liabilities as guarantor or otherwise with respect to obligations of others, or liabilities for taxes due or then accrued or to become due, of the Company, the Original Company or the Ceppeto Members or the constituent members and direct and indirect beneficial owners of any of them, existing prior to the Effective Date, or of Skyline I or Skyline II existing prior to February 7, 2001, regardless of whether the existence of such liability, obligation, claim, lien, cost, expense or encumbrance constitutes a breach of any of the representations and warranties of Richard Hadar, Eric Hadar and/or the Ceppeto Members or either of them contained in this Agreement. (b) SURVIVAL. The right of the BPLP Indemnified Parties to make claims for indemnification under SECTION 13.5(a)(2) and SECTION 13.5(a)(3) will survive the Effective Date indefinitely. With respect to claims for indemnification made by the BPLP Indemnified Parties under SECTION 13.5(a)(1), the following provisions will apply: (1) All representations and warranties of the Ceppeto Members contained in this Agreement shall survive the Effective Date regardless of any investigation made as follows: (A) the representations and warranties set forth in SECTION 5.1 (Organization and Power), SECTION 5.2 (Authorization) and SECTION 5.6 (Ownership of Direct and Indirect Interests in the Company) shall survive the Effective Date indefinitely; and (B) all other representations and warranties in this Agreement shall survive only until (but excluding) the date which is the second anniversary of the Effective Date (such representations and warranties described in clause (B), the "LIMITED SURVIVAL REPRESENTATIONS"). (2) With respect to any claim by a BPLP Indemnified Party for indemnification for a Loss resulting from the breach of the representations or warranties of the Ceppeto Members contained in this Agreement, a Notice of 71 Claim must be given to the Ceppeto Indemnitors within the survival period for the relevant representation or warranty. Notwithstanding the foregoing, (A) if a Notice of Claim asserting a claim for indemnification under this SECTION 13.5 arising from the breach of any Limited Survival Representation shall have been given prior to the expiration of such Limited Survival Representation, such Limited Survival Representation shall survive, only to the extent of the claim asserted in such Notice of Claim, until such claim is resolved, and (B) claims brought by any BPLP Indemnified Party in connection with any Limited Survival Representation which is untrue as a result of fraud by the Ceppeto Members may be brought at any time, without regard to the limitations on survival set forth in SECTION 13.5(b)(1). (c) LIMITATIONS ON CERTAIN INDEMNIFICATION OBLIGATIONS OF THE CEPPETO INDEMNITORS. (1) THIRD PARTY RECOVERIES. There shall be netted from any payment for a Loss required under SECTION 13.5(a): (A) the amount of any indemnification received by any BPLP Indemnified Party from an unrelated party with respect to such Loss, and (B) the amount of any insurance proceeds or other cash receipts paid to any BPLP Indemnified Party against any such Loss. (2) FULL RECOURSE. If the Ceppeto Indemnitors do not pay, in full, any and all indemnity obligations under SECTION 13.5(a) within the applicable time period set forth in SECTION 13.5(d)(4), the indemnity obligations of the Ceppeto Indemnitors under SECTION 13.5(a) shall, at BPLP Indemnified Parties' election, be satisfied by any BPLP Indemnified Party against the Ceppeto Members' Equity Interest pledged to the BP Member pursuant to SECTION 13.5(e), and/or any other collateral available to the BPLP Indemnified Parties hereunder, in such order as the BPLP Indemnified Parties may determine. In the event that the value of the Ceppeto Members' Equity Interest and/or any other collateral, is less than the amount of the Losses to be paid to the BPLP Indemnified Parties, the shortfall amount shall be a joint and several recourse obligation of all of the Ceppeto Indemnitors, and the BPLP Indemnified Parties shall be entitled to collect said shortfall from one or more of the Ceppeto Indemnitors, in the BPLP Indemnified Parties' discretion. (d) INDEMNIFICATION PROCEDURE. (1) NOTICE OF CLAIM. In the event that any BPLP Indemnified Party shall incur or suffer any Losses in respect of which indemnification may be sought pursuant to this SECTION 13.5, the BPLP Indemnified Party seeking to be indemnified (the "INDEMNITEE") shall promptly provide a notice (a "NOTICE OF CLAIM") to the Ceppeto Indemnitor from whom indemnification is sought (the "INDEMNITOR"), which Notice of Claim shall state the nature and basis of such claim, and the amount of the claim to the extent specified of otherwise known or 72 reasonably estimated. In the case of Losses arising by reason of any third party claim, the Notice of Claim shall be given promptly after the filing of any such claim against the Indemnitee or the determination by the Indemnitee that any such claim will ripen into a claim for which indemnification will be sought, but the failure of the Indemnitee to give the Notice of Claim within such time period shall not relieve the Indemnitor of any liability that the Indemnitor may have to the Indemnitee under this SECTION 13.5. (2) INFORMATION. The Indemnitee shall provide to the Indemnitor on request all information and documentation in the possession or under the control of the Indemnitee reasonably necessary to support and verify any Losses which the Indemnitee believes give rise to a claim for indemnification hereunder and shall give the Indemnitor reasonable access to all books, records and personnel in the possession or under the control of the Indemnitee that would have bearing on such claim. (3) THIRD PARTY CLAIMS. In the case of third party claims for which indemnification is sought, the Indemnitor shall have the option (A) to conduct any proceedings or negotiations in connection therewith, (B) to take all other steps to settle or defend any such claim (PROVIDED that the Indemnitor shall not, without the consent of the Indemnitee, settle any such claim (x) on terms which provide for (i) a criminal sanction or fine, (ii) injunctive relief or (iii) monetary damages in excess of the then value of the Ceppeto Members' Equity Interest (to the extent then pledged to the BP Member pursuant to SECTION 13.5(e) and (y) unless such settlement includes a full and unconditional release of the Indemnitee from all such claims, at no cost or other liability or obligation of the Indemnitee), and (C) to employ counsel, which counsel shall be selected by Indemnitee and shall be reasonably acceptable to the Indemnitor, to contest any such claim or liability in the name of the Indemnitor. In all such events, the Indemnitee shall be entitled to be represented by separate counsel at the Indemnitor's expense. So long as the Indemnitor has assumed defense of an action or claim, such action or claim shall not be settled without the Indemnitor's consent, which shall not unreasonably be withheld. The Indemnitor shall, within five (5) Business Days of receipt of the Notice of Claim, notify the Indemnitee of its intention to assume the defense of such claim. Until the Indemnitee has received notice of the Indemnitor's election whether to defend any claim, the Indemnitee shall take reasonable steps to defend (but may not settle) such claim. If the Indemnitor shall decline to assume the defense of any such claim, or shall fail to notify the Indemnitee within five (5) Business Days after receipt of the Notice of Claim of the Indemnitor's election to defend such claim, the Indemnitee may defend against and/or settle such claim. The costs and expenses of all proceedings, contests, lawsuits and/or settlements in respect of the claims described in this paragraph shall be borne solely by the Indemnitor. Regardless of which party shall assume the defense of the claim, the parties agree to cooperate fully with one another in connection therewith. 73 (4) PAYMENT OF LOSSES. If (and to the extent) the Indemnitor is responsible pursuant hereto to indemnify the Indemnitee in respect of a third party claim, then within thirty (30) days after the occurrence of a final non-appealable determination with respect to such third party claim (or sooner if (a) required by such determination or (b) Indemnitee is required to earlier pay, deposit or otherwise post all or any portion of such amount, or any amount in consideration thereof) and delivery of notice from the Indemnitee to the Indemnitor thereof, the Indemnitor shall pay the Indemnitee, in immediately available funds, the amount of any Losses (or such portion thereof as the Indemnitor shall be responsible for pursuant to the provisions hereof). If (and to the extent) the Indemnitor is responsible pursuant hereto to indemnify the Indemnitee for Losses that do not involve payment by the Indemnitee of a third party claim, then within thirty (30) days after agreement on the amount of such Losses or the occurrence of a final non-appealable determination of such amount (or such earlier date as provided above) and delivery of notice thereof by the Indemnitee to the Indemnitor, the Indemnitor shall pay to the Indemnitee in immediately available funds the amount of such Losses. Notwithstanding anything to the contrary contained herein, with respect to any claim in respect of which the Indemnitor is (or is reasonably expected to be) liable under this SECTION 13.5, the Indemnitor shall pay, within thirty (30) days after demand therefor by the Indemnitee, all out-of-pocket costs and expenses incurred by Indemnitee in connection with any such third party claim, including all legal fees and expenses associated therewith. (e) PLEDGE OF CEPPETO MEMBERS' EQUITY INTEREST. (1) On the Effective Date, the Ceppeto Members shall execute and deliver a Pledge and Security Agreement in the form attached to this Agreement as EXHIBIT C, pursuant to which the Ceppeto Members' Equity Interest will be pledged to the BP Member as security for the indemnification obligations of the Ceppeto Indemnitors under this SECTION 13.5. The Ceppeto Members shall, at their expense, execute and deliver all further instruments and documents, and take all further action, that may be necessary or desirable in order to create, perfect and protect the BP Member's security interest in the Ceppeto Members' Equity Interest granted or purported to be granted under the Pledge and Security Agreement, or to enable the BP Member to exercise its rights and remedies with respect to said security interest. (2) For so long as no Notice of Claim has been given, all distributions payable on account of the Ceppeto Members' Equity Interest shall be currently payable to the Ceppeto Members, notwithstanding the existence of the pledge. (3) Such pledge shall be released on the second (2nd) anniversary of the Effective Date (or such later date as is provided in the Pledge and Security Agreement) unless prior to such second (2nd) anniversary a Notice of Claim has been made in accordance with this SECTION 13.5, in which event the pledge will 74 remain in full force and effect until earlier of (i) the resolution and/or satisfaction in full of any and all claims set forth in such Notice of Claim (and the payment of any other amounts as set forth in the Pledge and Security Agreement) or (ii) the posting of substitute collateral in form and substance satisfactory to the Managing Member in its sole discretion and in an amount reasonably satisfactory to the Managing Member. Upon full satisfaction of any such claim or claims, the BP Member shall release the Ceppeto Members' Equity Interest from the lien of the Pledge and Security Agreement. ARTICLE 14. NOTICES 14.1.
