any reason there is any dispute or uncertainty concerning any action to be taken
hereunder, Escrow Agent shall take no action until it shall have received
instructions in writing concurred to by Seller and Purchaser or until directed
by a final order of judgment of a court of competent jurisdiction, whereupon
Escrow Agent shall take such action in accordance with such instructions or such
order.

                          (c) It is understood and agreed that the duties of
Escrow Agent are purely ministerial in nature. Escrow Agent shall not be liable
to the other parties hereto or to anyone else for any action taken or omitted by
it, including, without limitation, drawing on the Letter of Credit in accordance
with Section 2.2(d)(iii) above, or any action suffered by it to be taken or
omitted, in good faith and in the exercise of reasonable judgment, except for
acts of willful misconduct or negligence. Escrow Agent may rely conclusively and
shall be protected in acting upon any order, notice, demand, certificate,
opinion or advice of counsel (including counsel chosen by Escrow Agent),
statement, instrument, report or other paper or document (not only as to its due
execution and the validity and effectiveness of its provisions, but also as to
the truth and acceptability of any information therein contained) which is
reasonably believed by Escrow Agent to be genuine and to be signed or presented
by the proper person or persons. Escrow Agent shall not be bound by any notice
or demand, or any waiver, modification, termination or rescission of this
Agreement or any of the terms hereof, unless evidenced by a final judgment or
decree of a court of competent jurisdiction in the State of New York or a
Federal court in such State, or a writing delivered to Escrow Agent signed by
the proper party or parties and, if the duties or rights of Escrow Agent are
affected, unless it shall give its prior written consent thereto.

                          (d) Escrow Agent shall have the right to assume in the
absence of written notice to the contrary from the proper person or persons that
a fact or an event by reason of which an action would or might be taken by
Escrow Agent does not exist or has not occurred, without incurring liability to
the other parties hereto or to anyone else for any action taken or omitted, or
any action suffered by it to be taken or omitted, in good faith and in the
exercise of reasonable judgment, in reliance upon such assumption.

                          (e) Except in connection with Escrow Agent's willful
misconduct or negligence, Escrow Agent shall be indemnified and held harmless
jointly and severally by the other parties hereto from and against any and all
expenses or loss suffered by Escrow Agent (as Escrow Agent), including
reasonable attorneys' fees, in connection with any action, suit or other
proceeding involving any claim, which arises out of or relates to this
Agreement, the services of Escrow Agent hereunder or the monies held by it
hereunder. Promptly after the receipt by Escrow Agent of notice of any demand or
claim or the commencement of any action, suit or proceeding, Escrow Agent shall,
if a claim in respect thereof is to be made against any of the other parties
hereto, notify such other parties hereto in writing; but the failure by Escrow
Agent to give such notice shall not relieve any party from any liability which
such party may have to Escrow Agent hereunder.

                          (f) From time to time on and after the date hereof,
Seller and Purchaser shall deliver or cause to be delivered to Escrow Agent such
further documents and instruments and shall do and cause to be done such further
acts as Escrow Agent shall reasonably request (it being understood that Escrow
Agent shall have no obligation to make any such request) to carry out more
effectively the provisions and purposes of this Agreement, to evidence
compliance herewith or to assure itself that it is protected in acting
hereunder.

                          (g) If for any reason the Closing does not occur and
either party makes a written demand upon Escrow Agent for payment or refund, as
the case may be, of the Deposit (which shall, for the avoidance of doubt,
include the draw on, or the return of, the Letter of Credit) or any portion
thereof, Escrow Agent shall give written notice to the other party of such
demand. If Escrow Agent shall receive written notice from either party within
ten (10) Business Days after delivery of such notice instructing Escrow Agent
not to deliver the Deposit to the other party or to otherwise hold the Deposit,
or if for any reason there is any dispute or uncertainty concerning any action
to be taken pursuant to this Section 2.5(g) (but at all times subject to the
obligations of Escrow Agent under Section 2.2(d)(iii) hereof), Escrow Agent
shall take no action and shall continue to hold the Deposit until it has
received instructions in writing concurred to by Seller and Purchaser or until
directed by a final order of judgment of a court of competent jurisdiction,
whereupon Escrow Agent shall take such action in accordance with such
instructions or such order. If Escrow Agent does not receive a written objection
from the other party to the proposed payment or refund, as the case may be,
within ten (10) Business Days after the giving of the notice described in the
preceding sentence, Escrow Agent is hereby authorized to make such payment or
refund (and if the Deposit is a Letter of Credit, Escrow Agent may cause the
Letter of Credit to be drawn and the proceeds thereof to be delivered to Seller
or the Letter of Credit returned to Purchaser, as the case may be); provided,
however, if for any reason Escrow Agent in good faith shall elect not to make
such payment, Escrow Agent shall continue to hold such amount until otherwise
directed by written instructions from the parties to this Agreement or a final
judgment of a court of competent jurisdiction. Notwithstanding the foregoing,
Escrow Agent shall have the right at any time to deposit any cash Deposit
(including the proceeds of any Letter of Credit if converted to cash in
accordance with the provisions hereof) with the Clerk of the Supreme Court of
Queens County, New York, it being understood and agreed that in no event or
under any circumstance shall Escrow Agent be permitted to deposit the Letter of
Credit with the Clerk as aforesaid. Escrow Agent shall give written notice of
such deposit to Seller and Purchaser. Upon such deposit, Escrow Agent shall be
relieved and discharged of all further obligations and responsibilities
hereunder. Purchaser waives any right it may have to obtain an injunction or
other equitable relief to prevent Escrow Agent from drawing on the Letter of
Credit and depositing the same with the Clerk of the Supreme Court of Queens
County, New York.

                          (h) Escrow Agent may resign at any time as Escrow
Agent hereunder upon giving five (5) Business Days' prior written notice to that
effect to each of Seller and Purchaser. In such event, the successor Escrow
Agent shall be a nationally recognized title insurance company or a nationally
recognized law firm selected by Purchaser and reasonably accepted by Seller.
Such party that will no longer be serving as Escrow Agent shall deliver, against
receipt, to such successor Escrow Agent, the Deposit held by such party, to be
held by such successor Escrow Agent pursuant to the terms and provisions of this
Agreement. If no such successor has been designated on or before such party
ceases to be Escrow Agent hereunder, whether by resignation or otherwise, its
obligations as Escrow Agent shall continue until such successor is appointed;
provided, however, its sole obligation thereafter shall be to safely keep all
monies then held by it and to deliver the same to the person, firm or
corporation designated as its successor or until directed by a final order or
judgment of a court of competent jurisdiction, whereupon Escrow Agent shall make
disposition thereof in accordance with such order. If no successor Escrow Agent
is designated and qualified within five (5) Business Days after its resignation
is effective, such party that will no longer be serving as Escrow Agent shall
apply to the Clerk of the Supreme Court of Queens County, New York, for the
appointment of a successor Escrow Agent. Notwithstanding the foregoing, at any
time that Escrow Agent is holding the Letter of Credit, it shall be a condition
to such resignation that, and no resignation shall be effective until, the
Letter of Credit shall have been transferred to the successor Escrow Agent in
compliance with the requirements of the Letter of Credit. All costs of any such
transfer shall be paid by Purchaser.

                               STATUS OF THE TITLE

                  Section 3.1 Permitted Encumbrances. Subject to the terms and
provisions of this Agreement, Seller's interest in the Property shall be sold,
assigned and conveyed by Seller to Purchaser, and Purchaser shall accept same,
subject only to the following (collectively, the "Permitted Encumbrances"):

                          (a) the state of facts disclosed on the survey

contained in the ALTA form of owner's title policy currently in use in New York,
with the standard New York endorsement, and the easements, conditions,
restrictions, agreements and encumbrances as set forth on SCHEDULE 3.1(b)

                          (c) Non-Objectionable Encumbrances and any liens,
encumbrances or other title exceptions approved or waived by Purchaser as
provided in Section 4.1 of this Agreement;

                          (d) Property Taxes which are a lien but not yet due
and payable, subject to Section 6.1 of this Agreement;

                          (e) any and all present and future laws, rules,
regulations, statutes, ordinances, orders, special permits, approvals or other
legal requirements affecting the Property, including, without limitation, those
relating to zoning and land use;

                          (f) any utility company rights, easements and
franchises for electricity, water, steam, gas, telephone or other service or the
right to use and maintain poles, lines, wires, cables, pipes, boxes and other
fixtures and facilities in, over, under and upon the Property;

                          (g) any installment not yet due and payable of

                          (h) the City Agreements;

                          (i) the Restrictive Covenant;

                          (j) all violations of laws, rules, regulations,
statutes, ordinances, orders or requirements, now or hereafter issued or noted,
and any liens arising therefrom, if any; and

                          (k) the rights and interests held by Seller under the

                                   ARTICLE IV
                             TITLE INSURANCE, LIENS

                  Section 4.1 Title Objections. (a) The parties acknowledge that
Seller (at Purchaser's expense) has delivered or caused to be delivered to
Purchaser, and Purchaser has had an opportunity to review, title commitment
number LT050081 issued by Lawyers Title Insurance Corporation, title commitment
number 3605-00046 issued by Chicago Title Insurance Company and title commitment
number 3008-74662 issued by First American Title Insurance Company of New York
(collectively, the "Title Commitment") for an owner's policy of title insurance
with respect to Purchaser's acquisition of the Property. Purchaser shall
purchase and accept such owner's policy of title insurance from the Title
Companies, as co-insurers, each having the proportionate liabilities (with
respect to 50% of the aggregate value of the Title Policy, as selected by
Purchaser, and with respect to 50% of the aggregate value of the Title Policy,
as selected by Seller) as provided on SCHEDULE 4.1 with First American Title
Insurance Company of New York as the lead insurer, and Purchaser shall cause any
entity financing Purchaser's acquisition of the Property at Closing to similarly
accept its mortgagee's policy of title insurance from the Title Companies on the
same proportionate basis. Purchaser has heretofore given Seller notice of
Purchaser's objections (the "Title Objections") to those liens, encumbrances or
other title exceptions (other than Permitted Encumbrances) revealed by the Title
Commitment or has otherwise waived its right to do so. Any liens, encumbrances
and other title exceptions appearing on the Title Commitment which have not been
expressly objected to in a written notice to Seller prior to the date hereof
shall not constitute Title Objections and shall be deemed Permitted
Encumbrances.

                          (b) If, on or prior to the Closing Date, any of the
Title Companies shall deliver any update to the Title Commitment which discloses
additional liens, encumbrances or other title exceptions which were not
disclosed by the Title Commitment (each, an "Update Exception"), then Purchaser
shall have until the earlier of (x) five (5) Business Days after delivery of
such update or (y) the Business Day immediately preceding the Closing Date (or,
if the update was not delivered until the Closing Date, the Closing Date), time
being of the essence (the "Update Objection Date") to deliver notice to Seller
objecting to any of the Update Exceptions. If Purchaser fails to deliver such
objection notice by the Update Objection Date, Purchaser shall be deemed to have
waived its right to object to any Update Exceptions (and the same shall not be
deemed Title Objections and shall be deemed Permitted Encumbrances). If
Purchaser shall deliver such objection notice by the Update Objection Date, any
Update Exceptions which are not objected to in such notice shall not constitute
Title Objections and shall be deemed Permitted Encumbrances.

                          (c) Purchaser shall not be entitled to object to, and
shall be deemed to have approved, any liens, encumbrances or other title
exceptions (and the same shall not constitute Title Objections but shall be
deemed Permitted Encumbrances) (1) over which the Title Companies are willing to
insure (without additional cost to Purchaser), (2) against which the Title
Companies are willing to provide affirmative insurance (without additional cost
to Purchaser), or (3) which will be extinguished upon the transfer of the
Property (collectively, the "Non-Objectionable Encumbrances"). Notwithstanding
anything to the contrary contained herein, if Seller is unable to eliminate the
Title Objections set forth in the Title Commitment or any update thereto by the
Scheduled Closing Date, unless the same are waived by Purchaser without any
abatement in the Purchase Price, Seller may, upon at least two (2) Business
Days' prior notice (the "Title Cure Notice") to Purchaser (except with respect
to matters first disclosed during such two (2) Business Day period, as to which
matters notice may be given at any time through and including the Scheduled
Closing Date) adjourn the Scheduled Closing Date (such date to which Seller
adjourns the Scheduled Closing Date is herein referred to as the "Adjourned
Closing Date"), for a period not to exceed ninety (90) days ("the Title Cure
Period"), in order to attempt to eliminate such exceptions.



                                       13
<PAGE>

                  Section 4.2 Elections. If Seller is unable to eliminate any
Title Objection within the Title Cure Period, unless the same is waived by
Purchaser, then, Purchaser may (i) accept the Property subject to such Title
Objection without abatement of the Purchase Price, in which event (x) such Title
Objection shall be deemed to be, for all purposes, a Permitted Encumbrance, (y)
Purchaser shall close hereunder notwithstanding the existence of same, and (z)
Seller shall have no obligations whatsoever after the Closing Date with respect
to Seller's failure to cause such Title Objection to be eliminated, or (ii)
terminate this Agreement by notice given to Seller within ten (10) Business Days
following expiration of the Title Cure Period (or, if Seller does not elect to
adjourn the Scheduled Closing Date to enable Seller to eliminate a Title
Objection, within ten (10) Business Days following the Scheduled Closing Date),
time being of the essence, in which event Purchaser shall be entitled to a
return of the Deposit (together with any interest accrued thereon). If Purchaser
shall fail to deliver the termination notice described in clause (ii) of the
preceding sentence within the 10 Business Day period described therein, time
being of the essence, Purchaser shall be deemed to have made the election under
clause (i) of the preceding sentence. Upon the timely giving of any termination
notice under such clause (ii), this Agreement shall terminate and neither party
hereto shall have any further rights or obligations hereunder other than those
which are expressly provided to survive the termination hereof.

                  Section 4.3 No Actions. It is expressly understood that in no
event shall Seller be required to bring any action or institute any proceeding,
or to otherwise incur any costs or expenses in order to attempt to eliminate any
Title Objections or to otherwise cause title in the Property to be in accordance
with the terms of this Agreement on the Closing Date. Notwithstanding the
foregoing, Seller shall be obligated to expend up to $1,000,000 to cure any
Title Objection which can be satisfied, cured, discharged or otherwise removed
by the payment of a sum of money (including, without limitation, by depositing
up to $1,000,000 with the Title Companies in accordance with the provisions of
Section 4.5). The $1,000,000 cap described in the preceding sentence shall not
apply to liens which are voluntarily placed on the Property by Seller after the
date of this Agreement.

                  Section 4.4 Rescheduled Closing Date. If Seller shall have
adjourned the Scheduled Closing Date in order to cure Title Objections in
accordance with the provisions of Section 4.1, Seller shall, upon the
satisfactory cure thereof, promptly reschedule the Scheduled Closing Date, upon
at least five (5) Business Days' prior notice to Purchaser (the "New Closing
Notice").

                  Section 4.5 Disposition of Liens and Encumbrances. In lieu of
satisfying any liens or encumbrances required to be satisfied under this
Agreement, Seller may, at its option, deposit with the Title Companies such sum
of money or deliver to the Title Companies such affidavits and certificates as
may be determined by the Title Companies as being sufficient to induce the Title
Companies (i) to insure Purchaser and Purchaser's successors and assigns (at the
then current rate(s) of the Title Companies) against collection of liens and/or
encumbrances required to be eliminated by Seller (as hereinabove set forth) out
of or against the Property or Purchaser or such successors and assigns, and (ii)
to omit such liens and encumbrances from any title insurance policy issued to
any unrelated arm's-length lenders of Purchaser and Purchaser's successors and
assigns and the successors and assigns of such lenders, without additional
charge or premium, and provided further that the Title Companies agree, in
writing, to defend any action commenced by the holder of any lien or encumbrance
so insured against to enforce or collect the same at the sole cost and expense
of the Title Companies, in which event such liens and encumbrances shall not be
objections to title.

<PAGE>

                  Section 4.6 Seller Affidavits. If the Title Commitment
discloses judgments, bankruptcies or other returns against other persons having
names the same as, or similar to, that of Seller, Seller shall deliver to the
Title Companies affidavits (if truthful) showing that such judgments,
bankruptcies or other returns are not against Seller in order to induce the
Title Companies to omit exceptions with respect to such judgments, bankruptcies
or other returns or to insure over same. In addition, Seller shall deliver to
the Title Companies, all customary affidavits (if truthful) required to omit (i)
exceptions with respect to municipal emergency repairs, (ii) exceptions with
respect to (A) retroactive street vault charges, together with interest and
penalties thereon, and (B) work done by the City of New York upon the Property
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,
and (iv) any other exceptions of a similar type; provided that any of the
exceptions enumerated in clauses (i) - (iv) are customarily omitted from a title
report on the basis of an affidavit from the owner of the property being
insured, without the expenditure of money by such owner.

                  Section 4.7 Title Insurance. At Closing, the Title Companies
shall issue to Purchaser or be irrevocably committed to issue to Purchaser an
ALTA 1992 owner's form title insurance policy (the "Title Policy"), in the
amount of the Purchase Price, insuring that fee simple title to the Property is
vested in Purchaser subject only to the Permitted Encumbrances. Purchaser shall
be entitled to request that the Title Companies provide such endorsements (or
amendments) to the Title Policy as Purchaser may reasonably require, provided
that (a) such endorsements (or amendments) shall be at no cost to, and shall
impose no additional liability on, Seller, (b) Purchaser's obligations under
this Agreement shall not be conditioned upon Purchaser's ability to obtain such
endorsements and, if Purchaser is unable to obtain such endorsements, Purchaser
shall nevertheless be obligated to proceed to close the transaction contemplated
by this Agreement without reduction or set off against the Purchase Price, and
(c) the Closing shall not be delayed as a result of Purchaser's request.

                                    ARTICLE V
                                     CLOSING

                  Section 5.1 Closing. The Closing of the purchase and sale of
the Property shall be held on May 6, 2005 (such date, or the date Seller sets
for the Closing if Seller shall elect to extend this date pursuant to Section
4.1, or the date to which Purchaser adjourns the Closing in accordance with the
provisions of this Section 5.1, is herein referred to as the "Scheduled Closing
Date"), at 9:30 a.m. Eastern Time, at the offices of Paul, Hastings, Janofsky &
Walker LLP, 75 East 55th Street, New York, New York 10022. Purchaser shall have
the right to adjourn the Scheduled Closing Date from May 6, 2005 to a later
date, which adjournment may be exercised on up to, but not in excess of, three
(3) separate occasions, by written notice to Seller given at any time on or
before the then Scheduled Closing Date; provided, however, in no event or under
any circumstance shall the Scheduled Closing Date be extended, or the Closing
Date occur, beyond May 20, 2005 (the "Outside Closing Date"). In order to
facilitate the timely and expeditious closing of title and the payment of the
Purchase Price on the Scheduled Closing Date, Seller and Purchaser shall conduct
and complete a comprehensive pre-closing on the Business Day prior to the
Scheduled Closing Date. Time is of the essence as to the parties' obligation to
close the transactions contemplated herein on the Outside Closing Date.

                  Section 5.2 Seller's Closing Items. At the Closing, Seller
agrees to execute, deliver and/or provide to Purchaser, or cause to be executed,
delivered and provided to Purchaser, the following:

of Seller to execute the documents to be delivered by such entity on the Closing
Date) as may reasonably be required to enable the Title Companies to issue the
Title Policy without exception regarding Seller's authorization and authority
and as may be reasonably necessary to assure Purchaser that Seller has authority
to execute and deliver the Citi Lease;

                          (d) a "non-foreign person" certification from Seller
pursuant to Section 1445 of the Code in the form attached hereto as EXHIBIT E
(the "FIRPTA Affidavit");

                          (e) any bonds, warranties or guarantees, and any

part thereof in the possession or control of Seller;

                          (f) all architectural, mechanical or electrical plans
and specifications, interior floor plans, "as built" plans and surveys relating
to the Building, as well as all changes thereto, in the possession or control of
Seller;

                          (g) a certificate, dated as of the Closing Date,
stating that the representations and warranties of Seller contained in this
Agreement are true and correct in all material respects as of the Closing Date

of facts giving rise to the change do not have a material adverse effect on the
Property or the transactions contemplated herein);



                                       16
<PAGE>

                          (h) an estoppel certificate substantially in the form
contemplated by the Citi Lease, dated as of the Closing Date, duly executed by
Seller as the tenant under the Citi Lease (the "Citi Lease Estoppel");

attached hereto as EXHIBIT F (the "Restrictive Covenant");

                          (k) such other documents as may be reasonably
necessary or appropriate to effect the consummation of the transactions that are
the subject of this Agreement.

Seller shall be deemed to have delivered the items set forth in clauses (e) and
(f) above if the same are left in the management office of the Building on the
Closing Date.

                  Section 5.3 Purchaser's Closing Items. At the Closing,
Purchaser agrees to execute, deliver and/or provide to Seller, or cause to be
executed, delivered and/or provided to Seller, the following:

                          (a) the balance of the Purchase Price, in the manner
required by Section 2.2 of this Agreement;

                          (b) if requested, a Letter of Direction from Purchaser
directing Escrow Agent to pay the Purchase Price and all other amounts due at
Closing, in accordance with the provisions of this Agreement, to Seller or any
other person as Seller shall designate;

                          (c) a Secretary's Certificate certifying that the
Board of Directors of Purchaser has duly adopted resolutions authorizing the

certifying to the authority of the officers of such entity to execute the
documents to be delivered by such entity on the Closing Date;

                          (d) a certificate, dated as of the Closing Date,
stating that the representations and warranties of Purchaser contained in this
Agreement are true and correct in all material respects as of the Closing Date
(except to the extent that the last sentence of Section 10.2(c) is no longer
true and correct and the state of facts giving rise to such change is in
compliance with Section 16.5 of this Agreement and does not otherwise constitute
a breach by Purchaser of its obligations hereunder); and

                          (e) such other documents as may be reasonably
necessary or appropriate to effect the consummation of the transactions that are
the subject of this Agreement.

Seller by virtue of a favorable determination resulting from such protests shall
belong exclusively to Seller.

by the owner of the Property without penalty upon not more than thirty (30)
days' prior notice;

                              (iii) sell, assign, or convey any right, title or
interest whatsoever in or to the Property, or create or permit to exist any

required to obtain Purchaser's approval with respect to any transaction
described therein, Purchaser shall, within five (5) Business Days after receipt
of Seller's request therefor, notify Seller of its approval or disapproval of

five (5) Business Day period, Purchaser shall be deemed to have approved same.

                  Section 8.2 Purchaser's Inspection of the Property. (a) If
Purchaser shall hereafter inspect, test, investigate or survey all or any
portion of the Property, Purchaser shall restore such portion of the Property to
its condition existing immediately prior to Purchaser's inspection, testing,
investigation or survey thereof. Purchaser shall be liable for all damage or
injury to any person or property (including other portions of the Property)
resulting from, relating to or arising out of any such inspection, testing,
investigation or survey, whether occasioned by the acts of Purchaser or any of
its Representatives, and Purchaser shall promptly satisfy any lien that may

inspection, testing, investigation or survey. Purchaser shall indemnify, defend
and hold harmless Seller and its agents, employees, officers, directors,
affiliates, advisors and asset managers from any and all claims, damages or
liabilities resulting from any such inspection, testing, investigation or survey

                          (b) In conducting any inspection, testing,
investigation or surveying of the Property (or any portion thereof), neither
Purchaser nor any of Purchaser's Representatives shall (i) contact or have any
discussions with any of Seller's employees, agents or representatives, or with
any property managers of, tenants at, or contractors providing services to, the
Property, unless in each case Purchaser obtains the prior written consent of
Seller, it being agreed that all such contacts or discussions shall, pending any
such approval, be directed to Brian MacDonald, Citigroup, 666 Third Avenue, 21st
Floor, New York, New York 10017, Tel: (212) 551-7239, (ii) interfere with the
business of Seller conducted at the Property or (iii) damage the Property or any
portion thereof. In conducting any inspection, testing, investigation or
surveying, Purchaser and Purchaser's Representatives shall at all times comply
with, and shall be subject to, all other terms, covenants and conditions of this
Agreement. Seller may from time to time establish reasonable rules of conduct
for Purchaser and Purchaser's Representatives in furtherance of the foregoing.
Purchaser shall schedule and coordinate all inspections, testing, investigation,
or surveying, including, without limitation, any environmental test, with Seller
and shall give Seller at least two (2) Business Days' prior notice thereof.
Seller shall be entitled to have a representative present at all times during
each such inspection, testing, investigation or surveying. All inspection fees,
appraisal fees, survey fees, engineering fees and other costs and expenses of
any kind incurred by Purchaser or Purchaser's Representatives relating to such
inspection, testing, investigation or surveying of the Property (or any portion
thereof) shall be borne solely by Purchaser. Without limiting any other
requirements contained herein, prior to conducting any physical inspection,
testing, investigation or surveying of the Property, other than mere visual
examination, Purchaser shall obtain, and during the period of such inspection,
testing, investigation or surveying shall maintain, at Purchaser's sole cost and
expense, commercial general liability insurance, including a contractual
liability endorsement, and personal injury liability coverage, naming Seller,
its agents and employees as additional insureds, from an insurer reasonably
acceptable to Seller, which insurance must have limits for bodily injury and
death or damage to property of not less than $5,000,000 for any one occurrence.
Prior to making any such physical inspection, testing, investigation or
surveying, Purchaser shall furnish to Seller a certificate of insurance
evidencing the foregoing coverage. Purchaser and Purchaser's Representatives
shall not be permitted to conduct borings of the Property or drilling in or on
the Property in connection with the preparation of an environmental audit or in
connection with any other testing, inspection or investigation of the Property
without the prior written consent of Seller (and, if such consent is given,
Purchaser shall be obligated to pay to Seller on demand the cost of repairing
and restoring any damage as aforesaid). The provisions of this Section 8.2(b)
shall survive any termination of this Agreement.

                  Section 8.3 Post Closing Covenant. Purchaser expressly
acknowledges that the Lamppost Agreement and the Revocable Consent Agreement
cannot be assigned by Seller without the prior written consent of the Department
of Transportation of the City of the New York (the "Department"). Immediately

(iii) the filing fees required by Section 7-08 of Title 34, Chapter 7 of the
Rules of the City of New York and (iv) such other additional materials as may

fees in connection with the submission to the Department of the aforementioned
Petition Forms, Seller shall not be obligated to incur any expense or agree to
any conditions or requirements that may be imposed by the Department in order to
obtain such consent. If the Department refuses to consent to such assignment,
(i) Seller shall have the right (but not the obligation) to petition the
Department for a discontinuance of either or both of the Lamppost Agreement and
the Revocable Consent Agreement and Seller shall be obligated to pay all costs
and expenses arising from and directly related to the discontinuance and
termination thereof (including any alterations thereunder) and (ii) except as
provided in the immediately following sentence, Seller shall not have any
liability to Purchaser as a result of the failure to obtain such consent. Seller
shall indemnify and hold Purchaser harmless from all direct losses, costs,
damages (but expressly excluding consequential damages) and expenses (including
reasonable attorney fees) actually incurred by Purchaser (except to the extent
arising out of the negligence or willful misconduct of Purchaser) arising from
and directly related to Seller's discontinuance and termination of the Lamppost
Agreement and/or the Revocable Consent Agreement if the Department is unwilling
to consent to the assignment thereof to Purchaser. If the Department consents to
such assignment, then (y) Seller and Purchaser shall execute and deliver to each
other the assignment and assumptions referenced in the parentheticals contained
in Sections 5.4 (e) and (f) of this Agreement and (z) the security deposits
previously posted by Seller under the Lamppost Agreement and the Revocable
Consent Agreement shall be assigned by Seller to Purchaser and Seller shall
receive a credit against its next monthly obligation to pay fixed rent under the
Citi Lease in the amount of the security deposits previously posted by Seller
under the Lamppost Agreement ($2,000) and the Revocable Consent Agreement
($8,750). The provisions of this Section 8.3 shall survive the Closing.

                  Section 10.4 No Financing Contingency. Purchaser acknowledges
and agrees that its obligations under this Agreement shall not be subject to any
financing or other contingency and Purchaser shall have no right to terminate
this Agreement or receive a return of the Deposit (or the accrued interest
thereon) except as expressly provided for in Sections 4.2, 13.1(b), 14.1(b) and
15.2 hereof.

                  Section 10.5 Damages for Breach of Representations. In the
event the Closing occurs and it is determined subsequent to the Closing that
there was 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 for the actual damages suffered by such non-breaching
party with respect to such breach if and only if (i) the non-breaching party did
not have actual or constructive knowledge prior to the Closing that such
representation or warranty was untrue, inaccurate or incorrect (provided,
however, to the extent information furnished or made available to, or otherwise
obtained by, the non-breaching party contains information which is inconsistent
with such representation or warranty, the non-breaching party shall be deemed to
have actual knowledge that a representation or warranty was untrue, inaccurate
or incorrect), (ii) written notice of such breach is given to the breaching
party on or prior to the expiration of the applicable Survival Period (as
hereinafter defined) for such breach, which notice must contain a reasonably
detailed description of the facts relating to the claimed breach, and (iii) the
liability and losses arising out of such breach, when aggregated with all other
breaches, if any, of representations and warranties under this Agreement, shall

connection with any and all breaches of the representations and warranties of
Seller hereunder, an amount in excess of the net sales proceeds received by
Seller from Purchaser at the Closing (the "Proceeds"). Any such damages shall be
refunded from such Proceeds within thirty (30) days following the entry of such
final, non-appealable order and delivery of a copy thereof to Seller. Purchaser
acknowledges and agrees that, in the event that Seller shall be in breach of any
of the representations and warranties contained herein, Purchaser shall have no
recourse to the property or other assets of Seller (excluding the Proceeds), and
Purchaser's sole remedy, in such event, shall be to receive a refund from the
Proceeds in the amount described above. For purposes of this Section 10.5,
"Survival Period" shall mean: with respect to the representations and warranties
in Sections 10.1(a), 10.1(b), 10.2(a) and 10.2(b), a period without expiration,

                                  ARTICLE XIII
                             DAMAGE AND DESTRUCTION

                  Section 13.1 Effect of Damage. If all or any part of the
Property is damaged by fire or other casualty occurring following the date
hereof and prior to the Closing Date, whether or not such damage affects a
material part of the Property, then:

                          (a) if the estimated cost of repair or restoration is
less than or equal to $50,000,000 and if the estimated time to complete such
repair or restoration is twelve (12) months or less, neither party shall have
the right to terminate this Agreement and the parties shall nonetheless
consummate this transaction in accordance with this Agreement, without any
abatement of the Purchase Price or any liability or obligation on the part of
Seller by reason of said destruction or damage, except as hereinafter provided.
In such event, (i) Seller shall have the right to adjourn the Closing for a
period of time reasonably necessary in order to complete such repairs, (ii)
Seller shall have the right to make a claim for all insurance proceeds which
Seller may be entitled to receive as a result of such fire or other casualty,
and to retain all casualty insurance proceeds actually received under the
insurance policies in effect with respect to the Property on account of said
physical damage or destruction as shall be necessary to perform repairs to the
Building and/or to rebuild the Building to substantially the same condition as
it existed prior to the occurrence of such fire or other casualty and (iii)
Seller shall diligently pursue such repairs to completion.

                          (b) if the estimated cost of repair or restoration
exceeds $50,000,000 or if the estimated time to complete such repair or
restoration exceeds twelve (12) months, both Purchaser and Seller shall have the
option, exercisable within thirty (30) days after receipt of notice of the
occurrence of such fire or other casualty and such factual information regarding
the casualty and availability of insurance proceeds as is reasonably sufficient
to enable Purchaser or Seller, as the case may be, to make an informed decision
about whether or not to proceed to Closing, time being of the essence, to
terminate this Agreement by delivering notice thereof to the other party,
whereupon the Deposit (together with any interest accrued thereon) shall be
returned to Purchaser and this Agreement shall be deemed canceled and of no
further force or effect, and neither party shall have any further rights or
liabilities against or to the other except for such provisions which are
expressly provided in this Agreement to survive the termination hereof. If a
fire or other casualty described in this clause (b) shall occur and neither
Purchaser nor Seller shall have timely elected to terminate this Agreement, then
Purchaser and Seller shall consummate this transaction in accordance with this
Agreement, without any abatement of the Purchase Price or any liability or
obligation on the part of Seller by reason of said destruction or damage and, in
such event, Seller shall have the right to make a claim for and to retain any
casualty insurance proceeds received under the casualty insurance policies in
effect with respect to the Property on account of said physical damage or
destruction as shall be necessary to perform repairs to the Building and/or to
rebuild the Building to substantially the same condition as it existed prior to
the occurrence of such fire or other casualty.

                  Section 13.2 Estimates. The estimated cost to repair and/or
restore and the estimated time to complete contemplated in Section 13.1 above
shall be established by estimates obtained by Seller from independent
contractors, subject to Purchaser's review and reasonable approval of the same
and the provisions of Section 13.3 below.

                  Section 13.3 Disputes. The provisions of this Article XIII
supersede the provisions of Section 5-1311 of the General Obligations Law of the
State of New York. Any disputes under this Article XIII as to the cost of repair
or restoration or the time for completion of such repair or restoration shall be
resolved by expedited arbitration before a single arbitrator acceptable to both
Seller and Purchaser in their reasonable judgment in accordance with the
commercial arbitration rules of the American Arbitration Association; provided
that if Seller and Purchaser fail to agree on an arbitrator within five (5) days
after a dispute arises, then either party may request The Real Estate Board of
New York, Inc., to designate an arbitrator. Such arbitrator shall be an
independent architect or engineer having at least ten (10) years of experience
in the construction of office buildings in New York City. The determination of
the arbitrator shall be conclusive and binding upon the parties. The costs and
expenses of such arbitrator shall be borne equally by Seller and Purchaser.

                  Section 14.1 Effect of Condemnation. If, prior to the Closing
Date, any part of the Property is taken (other than a temporary taking), or if
Seller shall receive an official notice from any governmental authority having
eminent domain power over the Property of its intention to take, by eminent
domain proceeding, any part of the Property (a "Taking"), then:

                          (a) if such Taking involves ten percent (10%) or less
of the rentable area of the Building, neither party shall have any right to
terminate this Agreement, and the parties shall nonetheless consummate this
transaction in accordance with this Agreement, without any abatement of the
Purchase Price or any liability or obligation on the part of Seller by reason of
such Taking; provided, however, that Seller shall, on the Closing Date, (i)
assign and remit to Purchaser, and Purchaser shall be entitled to receive and
keep, the net proceeds of any award or other proceeds of such Taking which may
have been collected by Seller as a result of such Taking less the reasonable
expenses incurred by Seller in connection with such Taking, or (ii) if no award
or other proceeds shall have been collected, deliver to Purchaser an assignment
of Seller's right to any such award or other proceeds which may be payable to
Seller as a result of such Taking and Purchaser shall reimburse Seller for the
reasonable expenses incurred by Seller in connection with such Taking.

                          (b) if such Taking involves more than ten percent
(10%) of the rentable area of the Building, both Purchaser and Seller shall have
the option, exercisable within thirty (30) days after receipt of notice of such
Taking and such factual information regarding the Taking and the availability of
awards or other proceeds of such Taking as is reasonably sufficient to enable
Purchaser or Seller, as the case may be, to make an informed decision about
whether or not to proceed to Closing, time being of the essence, to terminate
this Agreement by delivering notice thereof to the other party, whereupon the
Deposit (together with any interest earned thereon) shall be returned to
Purchaser and this Agreement shall be deemed canceled and of no further force or
effect, and neither party shall have any further rights or liabilities against
or to the other except pursuant to the provisions of this Agreement which are
expressly provided to survive the termination hereof. If a Taking described in
this clause (b) shall occur and neither Purchaser nor Seller shall have timely
elected to terminate this Agreement, then Purchaser and Seller shall consummate
this transaction in accordance with this Agreement, without any abatement of the
Purchase Price or any liability or obligation on the part of Seller by reason of
such Taking; provided, however, that Seller shall, on the Closing Date, (i)
assign and remit to Purchaser, and Purchaser shall be entitled to receive and
keep, the net proceeds of any award or other proceeds of such Taking which may
have been collected by Seller as a result of such Taking less the reasonable
expenses incurred by Seller in connection with such Taking, or (ii) if no award
or other proceeds shall have been collected, deliver to Purchaser an assignment
of Seller's right to any such award or other proceeds which may be payable to
Seller as a result of such Taking and Purchaser shall reimburse Seller for the
reasonable expenses incurred by Seller in connection with such Taking.

                  Section 14.2 Estimates. The estimated extent of a Taking
contemplated in Section 14.1 above shall be established by estimates obtained by
Seller from an independent architect, subject to Purchaser's review and
reasonable approval of the same and the provisions of Section 14.3 below.

                  Section 14.3 Disputes. The provisions of this Article XIV
supersede the provisions of Section 5-1311 of the General Obligations Law of the
State of New York. Any disputes under this Article XIV as to whether the Taking
involves more than ten percent (10%) of the rentable area of the Building shall
be resolved by expedited arbitration before a single arbitrator acceptable to
both Seller and Purchaser in their reasonable judgment in accordance with the
commercial arbitration rules of the American Arbitration Association; provided
that if Seller and Purchaser fall to agree on an arbitrator within five (5) days
after a dispute arises, then either party may request The Real Estate Board of

                         DEFAULT BY PURCHASER OR SELLER

                  Section 15.1 Purchaser Default. If (i) Purchaser shall default
in the payment of the Purchase Price or if Purchaser shall default in the
performance of any of its other obligations to be performed on the Closing Date,
or (ii) Purchaser shall default in the performance of any of its obligations to
be performed prior to the Closing Date and, with respect to any default under
this clause (ii) only, such default shall continue for ten (10) days after
notice to Purchaser, Seller's sole remedy by reason thereof shall be retain the
Deposit (and any interest earned thereon), as liquidated damages for Purchaser's
default hereunder (it being agreed that the damages by reason of Purchaser's
default are difficult, if not impossible, to ascertain and the Deposit (and any
interest earned thereon) is a reasonable estimate of Seller's actual damages in
such event), and upon such receipt of the Deposit this Agreement shall be
terminated and thereafter Purchaser and Seller shall have no further rights or
obligations under this Agreement except for those that are expressly provided in
this Agreement to survive the termination hereof. If Seller terminates this
Agreement pursuant to a right given to it hereunder and Purchaser takes any
action which interferes with Seller's ability to sell, exchange, transfer,
lease, dispose of or finance the Property or takes any other actions with
respect thereto (including, without limitation, the filing of any lis pendens or
other form of attachment against the Property), then the named Purchaser (and
any assignee of Purchaser's interest hereunder) shall be liable for all loss,
cost, damage, liability or expense (including, without limitation, reasonable
attorneys' fees, court costs and disbursements and consequential damages)
incurred by Seller by reason of such action to contest by Purchaser.

                  Section 15.2 Seller Default. If (i) Seller shall default in
any of its obligations to be performed on the Closing Date, or (ii) Seller shall
default in the performance of any of its obligations to be performed prior to
the Closing Date and, with respect to any default under this clause (ii) only,
such default shall continue for ten (10) days after notice to Seller, Purchaser,
as its sole remedy by reason of such default (in lieu of prosecuting an action
for damages or proceeding with any other legal course of conduct, the right to
bring such actions or proceedings being expressly and voluntarily waived by
Purchaser, to the extent legally permissible, following and upon advice of its
counsel) shall have the right, subject to the other provisions of this Section
15.2, (x) to receive a return of the Deposit (together with any interest earned
thereon) or (y) solely in the event of a willful default by Seller, to seek to
obtain specific performance of Seller's obligations hereunder, provided that any
action for specific performance shall be commenced within sixty (60) days after
such default, it being understood that if Purchaser fails to commence an action
for specific performance within sixty (60) days after such default, Purchaser's
sole remedy shall be to receive a return of the Deposit (together with any
interest earned thereon). Upon such return and delivery, this Agreement shall
terminate and neither party hereto shall have any further obligations hereunder
except for those that are expressly provided in this Agreement to survive the
termination hereof. Notwithstanding the foregoing, Purchaser shall have no right
to seek specific performance if Seller shall be prohibited from performing its
obligations hereunder by reason of any law, regulation or other legal
requirement applicable to Seller.

                  Section 15.3 Survival. The provisions of this Article XV shall
survive the termination hereof.

                                  ARTICLE XVI
                            MISCELLANEOUS PROVISIONS

                  Section 16.1 Severability. Each part of this Agreement is
intended to be severable. If any term, covenant, condition or provision hereof
is unlawful, invalid, or unenforceable for any reason whatsoever, this Agreement
shall be construed without such term, covenant, condition or provision.

                  Section 16.2 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.

                  Section 16.3 Headings. The headings contained in this
Agreement are inserted for convenience only and shall not affect the meaning or
interpretation of this Agreement or any provision hereof.

                  Section 16.4 Construction. Unless the context otherwise
requires, singular nouns and pronouns, when used herein, shall be deemed to

                  Section 16.5 Assignment. Purchaser shall not assign its rights
under this Agreement to any other party without the prior written consent of
Seller; provided, however, that the Purchaser named herein shall have the
one-time right to assign this Agreement to a "Controlled Affiliate" (as defined
below). "Controlled Affiliate" shall mean any entity (i) controlled by Reckson
Operating Partnership, L.P. and (ii) at least twenty-five percent (25%) of the
beneficial interests in which are owned, directly or indirectly, by Reckson
Operating Partnership, L.P. as of the date of the assignment and the Closing
Date. "Controlled by" means the power and authority to direct the business and
affairs of the assignee by reason of the ownership of a majority of the
beneficial interests in such assignee, by contract or otherwise. Any such
assignment shall be conditioned upon Purchaser delivering to Seller an executed
original of the assignment and assumption agreement wherein the assignee assumes
all of the obligations of the Purchaser named herein and proof reasonably
satisfactory to Seller that the assignee constitutes a "Controlled Affiliate".
An assignment or transfer of this Agreement shall not relieve the Purchaser
named herein of any of its obligations hereunder or the transactions
contemplated hereby and the Purchaser named herein shall remain liable on a
joint and several basis with such assignee for the payment and performance of
Purchaser's obligations under this Agreement and the transactions contemplated
hereby which accrued prior to the date of such assignment. Except as set forth
in Section 16.9 below, this Agreement and the terms, covenants, conditions, and
provisions hereof, and the obligations, undertakings, rights and benefits
hereunder, including the exhibits and schedules hereto, shall be binding upon,
and shall inure to the benefit of, the undersigned parties and their respective
successors and assigns.

                  Section 16.6 Counterparts. This Agreement may be executed in
any number of counterparts, each of which shall constitute one and the same
instrument, and either party hereto may execute this Agreement by signing any
such counterpart.

                  Section 16.7 Governing Law. THIS AGREEMENT SHALL BE CONSTRUED,
AND THE RIGHTS AND OBLIGATIONS OF SELLER AND PURCHASER HEREUNDER DETERMINED, IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK AND FEDERAL STATUTORY
OR COMMON LAW, AS APPLICABLE, WITHOUT REFERENCE TO PRINCIPLES OF CONFLICTS OF
LAWS.

                  Section 16.8 Jurisdiction; Venue. For the purposes of any
suit, action or proceeding involving this Agreement, the parties hereto hereby
expressly submit to the jurisdiction of all federal and state courts sitting in
New York County in the State of New York and consent that any order, process,
notice of motion or other application to or by any such court or a judge thereof
may be served within or without such court's jurisdiction by registered mail or
by personal service, provided that a reasonable time for appearance is allowed,
and the parties hereto agree that such court shall have exclusive jurisdiction
over any such suit, action or proceeding commenced under this Agreement. Each
party hereby irrevocably waives any objection that it may have now or hereafter
to the laying of venue of any suit, action or proceeding arising out of or
relating to this Agreement brought in any federal or state court sitting in New
York County in the State of New York and hereby further irrevocably waives any
claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum.

other entity other than the parties hereto (and to the extent provided herein,
the other Seller Indemnified Parties and the other Purchaser Indemnified
Parties) shall have any rights or claims under this Agreement. The
representations, warranties, covenants and indemnities of each party hereunder
shall run to the benefit of the parties hereto only (and to the extent provided
herein, the other Seller Indemnified Parties and the other Purchaser Indemnified
Parties), and not to any successors, assigns or other third parties.

                  Section 16.10 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.

                  Section 16.11 Brokers and Advisors. (a) Seller and Purchaser
each warrants and represents to the other that it has not dealt or negotiated
with any broker other than Citigroup Global Markets Inc. in connection with the
sale of the Property as provided by this Agreement. Seller and Purchaser each
hereby agrees to indemnify and hold the other harmless from all loss, cost,
damage or expense (including reasonable attorney's fees) incurred by the other
as a result of any claim arising out of the acts of the indemnifying party (or
others on its behalf) for a commission, finder's fee or similar compensation
made by any broker, finder or any party (except Purchaser shall not have any
obligation to indemnify Seller against any such claim of Citigroup Global
Markets Inc. hereunder) who claims to have dealt with such party.

                          (b) Seller shall be responsible for the payment of any
sums due Citigroup Global Markets Inc. in its capacity as financial advisor to

and advisors retained by Purchaser in connection with the sale of the Property
as provided by this Agreement.

                          (c) The provisions of this Section 16.11 shall survive
the Closing.

                  Section 16.12 Integration. This Agreement sets forth the
entire agreement and understanding of the parties hereto with respect to the
specific matters agreed to herein 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.

                  Section 16.13 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 Property 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 16.13, 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 16.13 shall survive the
Closing or the termination of this Agreement.

                  Section 16.14 Amendments. This Agreement may not be changed,
modified or terminated, except by an instrument in writing signed by the parties
hereto.

                  Section 16.15 Further Assurances; Cooperation. The parties
will execute, acknowledge and deliver all and every such further acts, deeds,
conveyances, assignments, notices, transfers and assurances as may be reasonably
required for the better assuring, conveying, assigning, transferring and
confirming unto Purchaser the Property and for carrying out the intentions or
facilitating the consummation of the transactions contemplated by this
Agreement. In furtherance thereof, the parties hereto shall cooperate with each
other to effectuate the transactions contemplated by this Agreement and to
minimize transaction costs. The provisions of this Section 16.15 shall survive
the Closing for a period without expiration.

                  Section 16.16 Like Kind Exchange. (a) Seller has informed
Purchaser that it may seek in full or partial payment of the Purchase Price
like-kind property for the purpose of effectuating an exchange pursuant to
Section 1031 of the Code, and the regulations promulgated thereunder. To
facilitate such exchange, and as a material inducement to Seller to enter into
this Agreement, Purchaser consents (i) to an assignment by Seller of this
Agreement or of any of Seller's rights hereunder, including the right to receive
all or any portion of the Purchase Price, to a Qualified Intermediary (as
defined in Treasury Regulations Section 1.1031(k)-1(g)(4)) and (ii) to take such
other actions as are reasonably necessary to facilitate such like-kind exchange,
which shall in no event involve Purchaser acquiring title to or owning any
replacement property on behalf of Seller or incurring material expenses or
liability (unless such expenses or liability are reimbursed to Purchaser by
Seller). Purchaser agrees to reasonably cooperate with Seller in effectuating
the like-kind exchange and to execute all documents (subject to the reasonable
approval of Purchaser and its legal counsel) reasonably necessary in connection
therewith provided that such cooperation shall not (i) result in a reduction of
Purchaser's rights or an increase in Purchaser's obligations under this
Agreement other than to a de minimis extent, (ii) subject Purchaser to any
additional risks not expressly contemplated by this Agreement or (iii) delay the
Closing Date beyond the Outside Closing Date. Seller hereby agrees to indemnify
and hold harmless Purchaser from all loss, cost, damage, claim, liability and
expense (including without limitation, reasonable attorneys' fees) that may be
suffered or incurred by Purchaser, including any and all taxes, related to or
payable by reason of and as a direct result of (x) such exchange and/or (y) the
documents relating to or evidencing the exchange. In the event of a like-kind
exchange, on the Closing Date, (a) Seller shall, at the direction of the
Qualified Intermediary, convey title to the Property to Purchaser, (b) Purchaser
shall pay the balance of the Purchase Price (or the portion so assigned) to the
Qualified Intermediary or the Escrow Agent under this Agreement, (c) the Escrow
Agent shall pay over the Deposit to the Qualified Intermediary, and (d)
Purchaser shall execute such documents (subject to the reasonable approval of
Purchaser and its legal counsel) as may be reasonably necessary to acknowledge
the exchange. The Qualified Intermediary shall have the right to direct the
payment of the balance of the Purchase Price to separate accounts and/or
different persons, and Purchaser agrees to comply with such direction from the
Qualified Intermediary.

                          (b) Purchaser has informed Seller that it may acquire
the Property as part of an exchange pursuant to Section 1031 of the Code, and
the regulations promulgated thereunder. To facilitate such exchange, and as a
material inducement to Purchaser to enter into this Agreement, Seller consents
(i) to an assignment by Purchaser of this Agreement or of any of Purchaser's
rights hereunder to a Qualified Intermediary (as defined in Treasury Regulations
Section 1.1031(k)-1(g)(4)) and (ii) to take such other actions as are reasonably
necessary to facilitate such like-kind exchange, which shall in no event involve
Seller acquiring title to or owning or conveying any replacement property on
behalf of Purchaser or incurring material expenses or liability (unless such
expenses or liability are reimbursed to Seller by Purchaser). Seller agrees to
reasonably cooperate with Purchaser in effectuating the like-kind exchange and
to execute all documents (subject to reasonable approval of Seller and its legal
counsel) reasonably necessary in connection therewith provided that such
cooperation shall not (i) result in a reduction of Seller's rights or an
increase in Seller's obligations under this Agreement, other than to a de
minimis extent, (ii) subject Seller to any additional risks not expressly
contemplated by this Agreement or (iii) delay the Closing Date beyond the
Outside Closing Date. Purchaser hereby agrees to indemnify and hold harmless
Seller from all loss, cost, damage, claim, liability and expense (including
without limitation, reasonable attorneys' fees) that may be suffered or incurred
by Seller, including any and all taxes, related to or payable by reason of and
as a direct result of (x) such exchange and/or (y) the documents relating to or
evidencing the exchange. Nothing contained in Section 16.5 hereof shall restrict
any assignment described in this Section. No permitted assignment under this
Section shall relieve Purchaser of liability under this Agreement.
Notwithstanding the foregoing, whether or not Purchaser elects to acquire the
Property as part of an exchange pursuant to Section 1031 of the Code, the
transferee under the Deed to be delivered at the Closing shall be the Purchaser
named herein or a Controlled Affiliate of Purchaser.

                          (c) The indemnification provision contained in this
Section 16.16 shall survive the Closing.

                  Section 16.17 Intentionally Deleted.

                  Section 16.18 Citi Lease. Seller acknowledges that
notwithstanding anything to the contrary contained in this Agreement (including
Section 10.3 hereof), nothing in this Agreement shall be deemed to modify, limit
or waive any of the rights or obligations that the parties hereto may have to
the other with respect to matters arising subsequent to the Closing, as landlord
or tenant, as applicable, under the Citi Lease. The provisions of this Section
16.18 shall survive the Closing.

<PAGE>

                  Section 16.19 Continuing Seller Obligations; Indemnification.
(a) Seller agrees that Purchaser is not (pursuant to the terms of this
Agreement) assuming any of Seller's obligation under the Leases or the Contracts
or with respect to any Building employees and that, pursuant to the terms and
provisions of the Citi Lease, such obligations shall remain the obligations of
Seller subsequent to the Closing, subject to the terms and provisions of the
Citi Lease. From and after the Closing Date, Seller shall indemnify and hold
Purchaser harmless from all loss, cost, damages or expense (including reasonable
attorney's fees) incurred by Purchaser (except to the extent arising out of the
willful misconduct of Purchaser) to the extent the same arises out of third
party claims relating to the acts or omissions of Seller occurring prior to the
Closing Date under the Leases or the Contracts or with respect to Building
employees who were employed by Seller with respect to the operation of the
Property.

                          (b) If any claim is made with respect to which
Purchaser is entitled to indemnification under Section 16.19(a) above, Purchaser
shall provide written notice to Seller promptly after Purchaser has knowledge of
such claim, describing in reasonable detail the facts and circumstances giving
rise to such indemnification claim (but the failure to do so shall not relieve
Seller of its obligation to indemnify Purchaser as provided in Section 16.19(a)
above, except to the extent that Seller is prejudiced as a result of such
failure). In the case of any indemnification claim which is covered by
insurance, Purchaser shall cooperate in all reasonable respects with the
insurers in the exercise of their rights to investigate, defend or compromise
such indemnification claim as may be required to retain the benefits of such
insurance with respect to such indemnification claim.

                          (c) Seller shall have the sole right (to the exclusion
of Purchaser unless such claim is not being defended (by insurers or otherwise)
in a commercially reasonable manner by or on behalf of Seller, in which event
Purchaser shall have the right to participate in the defense of such claim) to
defend any third party claim for which indemnification is sought, and, at the
Seller's expense, Purchaser shall cooperate with all reasonable requests of
Seller in connection therewith. Purchaser shall supply Seller or such insurer
with such information and documents, and shall make such personnel available, as
may be requested by Seller or such insurer, that are reasonably necessary for
Seller or such insurer to defend or participate, or both, in any indemnification
claim. In addition, Seller shall have the sole right to compromise or otherwise
settle any third party claim for which indemnification is sought, subject to the
prior approval of Purchaser, which approval shall not be unreasonably withheld,
conditioned or delayed; provided, however, no such approval shall be required in
connection with any settlement where there is no admission of any wrong doing on
the part of Purchaser and no obligation or liability other than the payment of a
sum of money, which sum shall be fully paid by Seller, and Purchaser shall have
no other liability in connection therewith.

                          (d) Where the insurer under a policy of insurance
undertakes the defense of a claim for which indemnification is sought, or where
the same is otherwise being defended in a commercially reasonable manner, no
additional legal fees or expenses of the Purchaser in connection with the
defense of such claim shall be indemnified under Section 16.19(a) above unless
such fees or expenses were incurred at the request of Seller or such insurer;
provided, however, if the defendants in any such claim include both Seller and
Purchaser, and Purchaser has reasonably concluded that there are legal defenses
available to it which are inconsistent with those available to Seller, Purchaser
shall have the right to select separate counsel (subject to the reasonable
approval of Seller) to assert such legal defenses and to otherwise participate
in the defense of such action on behalf of Purchaser; provided, further,
however, that Seller shall not, in connection with any claim, be liable for the
expenses of more than one separate counsel at any time for Purchaser.

<PAGE>

                          (e) Upon payment in full of any indemnification claim
by Seller to or on behalf of Purchaser, Seller, without further action, shall be
subrogated to any and all claims that Purchaser may have in respect thereof
(other than claims in respect of insurance policies maintained by Purchaser at
its own expense or claims against an affiliate of Purchaser), and Purchaser
shall cooperate with Seller and give such further assurances as are reasonably
necessary to enable Seller vigorously to pursue such claims. Should Purchaser
receive any refund, in whole or in part, with respect to any indemnification
claim paid by Seller under Section 16.19(a) above, it shall promptly pay the
amount refunded over to Seller.

                          (f) The provisions of this Section 16.19 shall survive
the Closing.

                  Section 16.20 No Recording. Neither this Agreement nor any
memorandum hereof may be recorded without first obtaining Seller's consent
thereto.
