Ladies and Gentlemen:

     First Industrial, L.P., a Delaware limited partnership (the "Operating
Partnership"), by this agreement (the "Agreement") proposes to issue and sell to
the initial purchasers severally and not jointly named in Schedule II hereto
(collectively, the "Initial Purchasers"), for whom Chase Securities Inc. and
Credit Suisse First Boston Corporation are acting as representatives (in such
capacity, the "Representatives"), the principal amount of its debt securities
identified in Schedule I hereto (the "Securities"), each as specified in
Schedule I hereto.

     The sale of the Securities to the Initial Purchasers will be made without
registration under the Securities Act of 1933, as amended, and the rules and
regulations thereunder (the "Securities Act"), in reliance upon an exemption
therefrom. In connection with the sale of the Securities, the Operating
Partnership has prepared an offering memorandum dated March 12, 2001 (including
any documents incorporated by reference therein and any exhibits thereto, the
"Offering Memorandum") setting forth certain information concerning the
Operating Partnership, First Industrial Realty Trust, Inc., a Maryland
corporation and the sole general partner of the Operating Partnership (the
"Company") and the Securities, for the solicitation or purchase of, or the
offering of the Securities to the Subsequent Purchasers (as defined below).

     The Securities will be issued under an indenture, dated as of May 13, 1997
(the "Original Indenture"), between the Operating Partnership and U.S. Bank
Trust National Association, as trustee (the "Trustee"). The title, aggregate
principal amount, rank, interest rate or formula and timing of payments thereof,
stated maturity date, redemption and/or repayment provisions, sinking fund
requirements and any other variable terms of the Securities shall be established
by or pursuant to supplemental indenture No. 6 to the Original Indenture (as so
supplemented, and as the same may be amended or further supplemented from time
to time, the "Indenture") to be entered into between the Operating Partnership
and the Trustee on or prior to the Closing Date (as defined in Section 3).

     The Operating Partnership understands that the Initial Purchasers propose
to make an offering of the Securities on the terms and in the manner set forth
herein and agrees that the Initial Purchasers may resell, subject to the
conditions set forth herein, all or a portion of the Securities to purchasers
("Subsequent Purchasers") at any time after the date of this Agreement. The
Securities are to be offered and sold through the Initial Purchasers without
being registered under the Securities Act, in reliance upon exemptions
therefrom. Pursuant to the terms of the Securities and the Indenture, investors
that acquire Securities may only resell or otherwise transfer such Securities if
such Securities are hereafter registered under the Securities Act or if an
exemption from the registration requirements of the Securities Act is available
(including the exemption afforded by Rule 144A ("Rule 144A") or Regulation S
("Regulation S") of the Securities Act.

     The Initial Purchasers and their direct and indirect transferees will be
entitled to the benefits of a Registration Rights Agreement, to be dated as of
the Closing Date and to be substantially in the form attached hereto as Exhibit

     Each of the Company and the Operating Partnership hereby severally agrees
with the Initial Purchasers as follows:

     1. The Operating Partnership agrees to issue and sell the Securities to the

hereto at the purchase price set forth in Schedule I hereto plus accrued
interest, if any, from the date specified in Schedule I hereto to the date of
payment and delivery.

     2. The Operating Partnership understands that the Initial Purchasers intend
(i) to offer their respective portions of the Securities, as soon after this
Agreement has become effective as in the judgment of the Initial Purchasers is
advisable, to the Subsequent Purchasers in reliance on Rule 144A or Regulation S
and (ii) initially to offer the Securities upon the terms set forth in the
Offering Memorandum.

     The Operating Partnership and the Company confirm that they have authorized

involving a public offering within the meaning of Section 4(2) of the Securities
Act and (B) it will solicit offers for the Securities only from, and will offer
the Securities only to, persons who it reasonably believes to be (1) "qualified
institutional buyers" within the meaning of Rule 144A under the Securities Act
or (2) non-U.S. persons outside the United States, as determined under
Regulation S, to whom each Initial Purchaser reasonably believes offers and
sales may be made in reliance on Regulation S.

     3. Payment for the Securities shall be made to the Operating Partnership or

Purchasers acquire such Securities in good faith and without notice of any such
security interests, mortgages, pledges, liens, encumbrances, claims or equities.

     (xiii) The information in the Offering Memorandum under "Description of the
Notes," "Certain United States Federal Income Tax Considerations," "Exchange
Offer; Registration Rights," and "Risk Factors," to the extent that it
constitutes statements of law, descriptions of statutes, rules or regulations,
or summaries of documents or legal conclusions, has been reviewed by us and is
correct in all material respects and presents fairly the information required to
be disclosed therein.

accordance with Sections 2 and 8 of this Agreement to each Subsequent Purchaser
solely in the manner and under the circumstances contemplated by this Agreement

     (ii) The execution and delivery of this Agreement and the Indenture and the

the Operating Partnership did not and do not conflict with, or constitute a
breach or violation of, or default under: (A) any or all of the Credit

or FIP, of which, in the cases of clauses (B) and (C) above, such counsel is

in the aggregate, would not have a Material Adverse Effect.

     (iii) To the knowledge of such counsel, there are no legal or governmental
proceedings pending or threatened that do, or are likely to, have a Material
Adverse Effect.

     (iv) The information in the Company Annual Report of Form 10-K under the

the Company's Consolidated Financial Statements to the extent that it
constitutes statements of law, descriptions of statutes, summaries of principal
financing terms of Credit Documents or legal conclusions, has been reviewed by
such counsel and is correct in all material respects and presents fairly the
information disclosed therein.

to you and counsel for the Initial Purchasers), dated the Closing Date, of
Cahill Gordon & Reindel, counsel for the Company and the Operating Partnership,
to the effect that:

          We are of the opinion that, commencing with the Company's taxable year

     requirements of the Code necessary to qualify as a REIT, it will continue
     to so qualify.

     (j) On the date hereof, the Accountants shall have furnished to the Initial
Purchasers a letter, dated the date of its delivery, addressed to the Initial
Purchasers and in form and substance satisfactory to the Initial Purchasers (and
to its counsel), confirming that they are independent public accountants with
respect to the Operating Partnership, the Company and the Subsidiaries as
required by the Securities Act and with respect to the financial and other
statistical and numerical information contained in the Offering Memorandum and
containing statements and information of the type ordinarily included in
accountants' "comfort letters" as set forth in the AICPA's Statement on Auditing
Standards 72. At the Closing Date, the Accountants shall have furnished to the
Initial Purchasers a letter, dated the date of its delivery, which shall
confirm, on the basis of a review in accordance with the procedures set forth in
the letter from it, that nothing has come to its attention during the period
from the date of the letter referred to in the prior sentence to a date
(specified in the letter) not more than five days prior to the Closing Date,
which would require any change in its letter dated the date hereof if it were
required to be dated and delivered at the Closing Date;

     (k) You shall have received on the Closing Date an opinion, dated the
Closing Date, of Clifford Chance Rogers & Wells LLP ("Clifford Chance Rogers &
Wells"), counsel for the Initial Purchasers, as to the matters referred to in
clause (i) (with respect to the Company only) of Section 7(g) and clauses (ii)
(with respect to the Operating Partnership and the first sentence only), (iv),
(v), (vi), (vii), (viii) and (xiv) of Section 7(f) and in addition, Clifford
Chance Rogers & Wells shall make statements similar to those contained in the
first paragraph following Section 7(f)(xvii) hereto and shall be entitled to
rely on those persons described in the second paragraph following Section
7(f)(xvii) hereto with respect to the matters described therein.

     (l) At the Closing Date, the Securities shall have the ratings accorded by
any "nationally recognized statistical organization," as defined by the
Commission for purposes of Rule 436(g)(2) under the Act if and as specified in
Schedule I hereto, and the Operating Partnership shall have delivered to the
Representatives a letter, dated as of such date, from each such rating
organization, or other evidence satisfactory the Representatives, confirming
that the Securities have such ratings. Since the date hereof, there shall not
have occurred a downgrading in the rating assigned to the Securities or any of
the Company's securities or the Operating Partnership's other securities by any
such rating organization, and no such rating organization shall have publicly
announced that it has under surveillance or review, with possible negative
implications, its rating of the Securities or any of the Company's securities or
the Operating Partnership's other securities.

     (m) At the Closing Date, counsel for the Initial Purchasers shall have been
furnished with such documents and opinions as they may reasonably require for
the purpose of enabling them to pass upon the issuance and sale of the
Securities, as herein contemplated and related proceedings, or in order to
evidence the accuracy of any of the representations or warranties, or the
fulfillment of any of the conditions, herein contained; and all proceedings
taken by the Operating Partnership and the Company in connection with the
issuance and sale of the Securities as herein contemplated shall be reasonably
satisfactory in form and substance to the Initial Purchasers and counsel for the
Initial Purchasers.

     The opinions and certificates mentioned in this Agreement shall be deemed
to be in compliance with the provisions hereof only if they are in all material
respects satisfactory to you and to Clifford Chance Rogers & Wells, counsel for
the Initial Purchasers.

     8. Each of the Initial Purchasers and the Operating Partnership hereby
establish and agree to observe the following procedures in connection with the
offer and sale of the Securities:

                                       21
<PAGE>

     (a) Offers, sales and deliveries of the Securities shall only be made (x)
to persons whom the offeror or seller reasonably believes to be "qualified
institutional buyers" (as defined in Rule 144A under the Securities Act) or (y)
non-U.S. persons outside the United States, as defined in Regulation S under the
Securities Act, to whom the offeror or seller reasonably believes offers and
sales of the Securities may be made in reliance upon Regulation S under the
Securities Act. Each Initial Purchaser agrees that it will not offer, sell or
deliver any of the Securities in any jurisdiction outside the United States
except under circumstances that will result in compliance with the applicable
laws thereof, and that it will take at its own expense whatever action is
required to permit its purchase and resale of the Securities in such
jurisdictions.

     (i) No general solicitation or general advertising (within the meaning of
Rule 502(c) under the Securities Act) will be used in the United States in
connection with the offering or sale of the Securities.

     (ii) In the case of a non-bank Subsequent Purchaser of a Security acting as
a fiduciary for one or more third parties, each such third party shall, in the
judgment of the applicable Initial Purchaser, be a Qualified Institutional Buyer
or a non-U.S. person outside the United States.

     (iii) Each Initial Purchaser will take reasonable steps to inform, and
cause each of its U.S. Affiliates to take reasonable steps to inform, persons
acquiring Securities from such Initial Purchaser or affiliate, as the case may
be, in the United States that the Securities (a) have not been and will not be
registered under the Securities Act, (b) are being sold to them without
registration under the Securities Act in reliance on Rule 144A or in accordance
with another exemption from registration under the Securities Act, as the case
may be, and (c) may not be offered, sold or otherwise transferred except (1) to
the Operating Partnership, (2) outside the United States in accordance with
Regulation S, or (3) inside the United States in accordance with (x) Rule 144A
to a person whom the seller reasonably believes is a Qualified Institutional
Buyer that is purchasing such Securities for its own account or for the account
of a Qualified Institutional Buyer to whom notice is given that the offer, sale
or transfer is being made in reliance on Rule 144A or (y) pursuant to another
available exemption from registration under the Securities Act.

     (iv) No sale of the Securities to any one Subsequent Purchaser will be for
less than U.S. $1,000 principal amount and no Security will be issued in a
smaller principal amount. If the Subsequent Purchaser is a non-bank fiduciary
acting on behalf of others, each person for whom it is acting must purchase at
least U.S. $100,000 principal amount of the Securities.

     (v) The transfer restrictions and the other provisions set forth in the
Offering Memorandum under the heading "Notice to Investors," including the
legend required thereby, shall apply to the Securities except as otherwise
agreed by the Operating Partnership and the Initial Purchasers.

     (vi) Each Initial Purchaser will deliver to each Subsequent Purchaser of
the Securities, in connection with its original distribution of the Securities,
a copy of the Offering Memorandum, as amended and supplemented at the date of
such delivery, if required by applicable law.

     (b) The Operating Partnership covenants with each Initial Purchaser as
follows:

     (i) The Operating Partnership agrees that, in order to render the
Securities eligible for resale pursuant to Rule 144A under the Securities Act,
while any of the Securities remain outstanding, it will make available, upon
request, to any holder of Securities or prospective purchasers of

                                       22
<PAGE>

Securities the information specified in Rule 144A(d)(4), unless the Operating
Partnership furnishes information to the Commission pursuant to Section 13 or
15(d) of the Exchange Act; and

     (ii) Until the expiration of two years after the original issuance of the
Securities, the Operating Partnership will not, and will cause its Affiliates
not to, purchase or agree to purchase or otherwise acquire any Securities which
are "restricted securities" (as such term is defined under Rule 144(a)(3) under
the Securities Act), whether as beneficial owner or otherwise (except as agent
acting as a securities broker on behalf of and for the account of customers in
the ordinary course of business in unsolicited broker's transactions), unless
such repurchased Securities are promptly retired.

     (c) Each Initial Purchaser understands that the Securities have not been
and will not be registered under the Securities Act and may not be offered or
sold within the United States or to, or for the account or benefit of, U.S.
persons except in accordance with Regulation S under the Securities Act or
pursuant to an exemption from the registration requirements of the Securities
Act. Each Initial Purchaser severally represents and agrees that it has offered
and sold Securities and will offer and sell Securities (i) as part of their
distribution at any time and (ii) otherwise until forty days after the later of
the date upon which the offering of the Securities commences and the Closing
Date, only in accordance with Rule 903 of Regulation S, or another applicable
exemption from the registration provisions of the Securities Act or Rule 144A
under the Securities Act. Accordingly, neither the Initial Purchasers, their
affiliates nor any persons acting on their behalf have engaged or will engage in
any directed selling efforts with respect to Securities, and the Initial
Purchasers, their affiliates and any person acting on their behalf have complied
and will comply with the offering restriction requirements of Regulation S. Each
Initial Purchaser agrees that, at or prior to confirmation of a sale of
Securities (other than a sale of Securities pursuant to Rule 144A) it will have
sent to each distributor, dealer or person receiving a selling concession, fee
or other remuneration that purchases Securities from it or through it during the
restricted period a confirmation or notice to substantially the following
effect:

     "The Securities covered hereby have not been registered under the
Securities Act and may not be offered or sold within the United States or to or
for the account or benefit of U.S. persons (i) as part of their distribution at
any time and (ii) otherwise until forty days after the later of the date upon
which the offering of the Securities commenced and the date of closing, except
in either case in accordance with Regulation S, Rule 144A under the Securities
Act or another exemption from the registration requirements of the Securities
Act. Terms used above have the meaning given to them by Regulation S."

     Terms used in the above paragraph have the meanings given to them by
Regulation S.

     (d) Each Initial Purchaser severally represents and agrees that it has not
entered and will not enter into any contractual arrangements with respect to the
distribution of the Securities, except with its affiliates or with the prior
written consent of the Operating Partnership.

     9. The Company and the Operating Partnership, jointly and severally, agree
to indemnify and hold harmless each Initial Purchaser and each person, if any,
who controls any Initial Purchaser within the meaning of either Section 15 of
the Securities Act or Section 20 of the Exchange Act, from and against any and
all losses, claims, damages and liabilities (including without limitation the
legal fees and other expenses incurred in connection with any suit, action or
proceeding or any claim asserted) caused by any untrue statement or alleged
untrue statement of a material fact contained in the Offering Memorandum (as
amended or supplemented if the Company or the Operating Partnership shall have

                                       23
<PAGE>

furnished any amendments or supplements thereto) or any preliminary offering
memorandum, or caused by any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, except insofar as such losses, claims, damages or
liabilities are caused by any untrue statement or omission or alleged untrue
statement or omission made in reliance upon and in conformity with information
relating to any Initial Purchaser furnished to the Company or the Operating
Partnership in writing by such Initial Purchaser through you expressly for use
therein; provided, that the foregoing indemnity with respect to any preliminary
offering memorandum shall not inure to the benefit of any Initial Purchaser (or
to the benefit of the person controlling such Initial Purchaser) from whom the
person asserting any such losses, claims, damages or liabilities purchased
Securities if such untrue statement or omission or alleged untrue statement or
omission made in such preliminary offering memorandum supplement is eliminated
or remedied in the Offering Memorandum (as amended or supplemented if the
Company or the Operating Partnership shall have furnished any amendments or
supplements thereto) and, if required by law, a copy of the Offering Memorandum
(as so amended or supplemented) shall not have been furnished to such person at
or prior to the written confirmation of the sale of such Securities to such
person.

     Each Initial Purchaser agrees, severally and not jointly, to indemnify and
hold harmless the Company and the Operating Partnership, and the Company's and
the Operating Partnership's officers and directors and each person who controls
the Company or the Operating Partnership within the meaning of Section 15 of the
Securities Act and Section 20 of the Exchange Act, to the same extent as the
foregoing indemnity from the Company and the Operating Partnership to each
Initial Purchaser, but only with reference to information relating to such
Initial Purchaser furnished to the Company and the Operating Partnership in
writing by such Initial Purchaser through you expressly for use in the Offering
Memorandum, any amendment or supplement thereto, or any preliminary offering
memorandum. For purposes of this Section 9, the only written information
furnished by the Initial Purchasers to the Company expressly for use in the
Offering Memorandum is the name of the Initial Purchasers on the front cover and
in the "Plan of Distribution" section, the second paragraph following the table
in the "Plan of Distribution" section and the last two paragraphs in the "Plan
of Distribution" section.

     If any suit, action, proceeding (including any governmental or regulatory
investigation), claim or demand shall be brought or asserted against any person
in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person (the "Indemnified Person") shall promptly
notify the person against whom such indemnity may be sought (the "Indemnifying
Person") in writing, and the Indemnifying Person, upon request of the
Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others the
Indemnifying Person may designate in such proceeding and shall pay the fees and
expenses of such counsel related to such proceeding. In any such proceeding, any
Indemnified Person shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Person
unless (i) the Indemnifying Person and the Indemnified Person shall have
mutually agreed to the contrary, (ii) the Indemnifying Person has failed within
a reasonable time to retain counsel reasonably satisfactory to the Indemnified
Person or (iii) the named parties in any such proceeding (including any
impleaded parties) include both the Indemnifying Person and the Indemnified
Person and representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. It is
understood that the Indemnifying Person shall not, in connection with any
proceeding or related proceeding in the same jurisdiction, be liable for the
fees and expenses of more than one separate firm (in addition to any local
counsel) for all Indemnified Persons, and that all such fees and expenses shall
be reimbursed as they are incurred. Any such separate firm for the Initial
Purchasers and such control persons of Initial Purchasers shall be designated in
writing by the Representatives and any such separate firm for the Company, the
Operating Partnership, their directors, officers and such control persons of the
Company and the Operating Partnership or authorized

                                       24
<PAGE>

representatives shall be designated in writing by the Company or the Operating
Partnership. The Indemnifying Person shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with such
consent or if there be a final judgment for the plaintiff, the Indemnifying
Person agrees to indemnify any Indemnified Person from and against any loss or
liability by reason of such settlement or judgment. Notwithstanding the
foregoing sentence, if at any time an Indemnified Person shall have requested an
Indemnifying Person to reimburse the Indemnified Person for fees and expenses of
counsel as contemplated by the third sentence of this paragraph, the
Indemnifying Person agrees that it shall be liable for any settlement of any
proceeding effected without its written consent if (i) such settlement is
entered into more than 30 days after receipt by such Indemnifying Person of the
aforesaid request and (ii) such Indemnifying Person shall not have reimbursed
the Indemnified Person in accordance with such request prior to the date of such
settlement. If it is ultimately determined that an Indemnified Person was not
entitled to indemnification hereunder, such Indemnified Person shall be
responsible for repaying or reimbursing the Indemnifying Person for any amounts
so paid or incurred by such Indemnifying Person pursuant to this paragraph. No
Indemnifying Person shall, without the prior written consent of the Indemnified
Person, effect any settlement of any pending or threatened proceeding in respect
of which any Indemnified Person is or could have been a party and indemnity
could have been sought hereunder by such Indemnified Person, unless such
settlement includes an unconditional release of such Indemnified Person from all
liability on claims that are the subject matter of such proceeding.

     If the indemnification provided for in the first and second paragraphs of
this Section 9 is unavailable to an Indemnified Person in respect of any losses,
claims, damages or liabilities referred to therein, then each Indemnifying
Person under such paragraph, in lieu of indemnifying such Indemnified Person
thereunder, shall contribute to the amount paid or payable by such Indemnified
Person as a result of such losses, claims, damages or liabilities (a) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Operating Partnership on the one hand and the Initial Purchasers
on the other hand from the offering of the Securities or (b) if the allocation
provided by clause (a) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (a) above but also the relative fault of the Company and the
Operating Partnership on the one hand and the Initial Purchasers on the other in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations. The relative benefits received by the Company and the Operating
Partnership on the one hand and the Initial Purchasers on the other shall be
deemed to be in the same respective proportions as the net proceeds from the
offering of such Securities (before deducting expenses) received by the Company
and the Operating Partnership and the total discounts and the commissions
received by the Initial Purchasers bear to the aggregate public offering price
of the Securities. The relative fault of the Company and the Operating
Partnership on the one hand and the Initial Purchasers on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company and the Operating
Partnership on the one hand or by the Initial Purchasers on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

     The Company, the Operating Partnership and the Initial Purchasers agree
that it would not be just and equitable if contribution pursuant to this Section
9 were determined by pro rata allocation (even if the Initial Purchasers were
treated as one entity for such purpose) or by any other method of allocation
that does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an Indemnified
Person as a result of the losses, claims, damages and liabilities referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
Indemnified Person in connection with investigating or defending any such action
or claim. Notwithstanding the

                                       25
<PAGE>

provisions of this Section 9, in no event shall an Initial Purchaser be required
to contribute any amount in excess of the amount by which the total price at
which the Securities purchased by it were offered exceeds the amount of any
damages that such Initial Purchaser has otherwise been required to pay by reason
of such untrue or alleged untrue statement or omission or alleged omission. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Initial Purchasers'
obligations to contribute pursuant to this Section 9 are several in proportion
to the respective principal amounts of Securities set forth opposite their names
in Schedule II hereto, and not joint,

     The remedies provided for in this Section 9 are not exclusive and shall not
limit any rights or remedies which may otherwise be available to any indemnified
party at law or in equity.

     The indemnity and contribution agreements contained in this Section 9 and
the representations, warranties and covenants of the Company and the Operating
Partnership set forth in this Agreement shall remain operative and in full force
and effect regardless of (a) any termination of this Agreement, (b) any
investigation made by or on behalf of any Initial Purchaser or any person
controlling any Initial Purchaser or by or on behalf of the Company, its
officers or directors or any other person controlling the Company or the
Operating Partnership and (c) acceptance of and payment for any of the
Securities.

     10. Notwithstanding anything herein contained, this Agreement may be
terminated in your absolute discretion by notice given to the Operating
Partnership, if after the execution and delivery of this Agreement and prior to
the Closing Date (a) the Company and the Operating Partnership shall have
failed, refused or been unable, at or prior to the Closing Date, to perform any
agreements on its part to be performed hereunder, (b) any other conditions to
the Initial Purchasers' obligations hereunder are not fulfilled, (c) trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, the American Stock Exchange, the
National Association of Securities Dealers, Inc., the Chicago Board Options
Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (d)
trading of any securities of or guaranteed by the Company and the Operating
Partnership shall have been suspended on any exchange or in any over-the-counter
market, (e) a general moratorium on commercial banking activities in New York
shall have been declared by either Federal or New York State authorities; or (f)
there shall have occurred any outbreak or escalation of hostilities or any
change in financial markets or any calamity or crisis that, in your judgment, is
material and adverse and which, in your judgment, makes it impracticable to
market the Securities on the terms and in the manner contemplated in the
Offering Memorandum.

     11. If, on the Closing Date, any one or more of the Initial Purchasers
shall fail or refuse to purchase Securities which it or they have agreed to
purchase under this Agreement, and the aggregate principal amount of Securities,
which such defaulting Initial Purchaser or Initial Purchasers agreed but failed
or refused to purchase is not more than one-tenth of the aggregate principal
amount of the Securities, the other Initial Purchaser or Initial Purchasers
shall be obligated severally in the proportions that the principal amount of
Securities set forth opposite their respective names in Schedule II hereto bears
to the aggregate principal amount of Securities set forth opposite the names of
all such non-defaulting Initial Purchasers, or in such other proportions as the
non-defaulting Initial Purchasers may specify, to purchase the Securities which
such defaulting Initial Purchaser or Initial Purchasers agreed but failed or
refused to purchase on such date; provided that in no event shall the principal
amount of Securities that any Initial Purchaser has agreed to purchase pursuant
to Section 1 be increased pursuant to this Section 11 by an amount in excess of
one-ninth of such principal amount of Securities without the written consent of
such Initial Purchaser. If, on the Closing Date, any Initial Purchaser or
Initial Purchasers shall fail or refuse to purchase Securities and the aggregate
principal amount of Securities with respect to which such default occurs is more
than one-tenth of the aggregate principal amount of Securities to be purchased,
and arrangements satisfactory to the Initial Purchasers and the Operating

Partnership for the purchase of such Securities are not made within 36 hours
after such default, this Agreement shall terminate without liability on the part
of any non-defaulting Initial Purchaser or the Operating Partnership. In any
such case either you or the Company and the Operating Partnership shall have the
right to postpone the Closing Date, but in no event for longer than seven days,
in order that the required changes, if any, in the Offering Memorandum or in any
other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Initial Purchaser from liability in
respect of any default of such Initial Purchaser under this Agreement.

     12. If this Agreement shall be terminated by the Initial Purchasers, or any
of them, because of any failure or refusal on the part of the Company and the
Operating Partnership to comply with the terms or to fulfill any of the
conditions of this Agreement, or if for any reason the Company and the Operating
Partnership shall be unable to perform their obligations under this Agreement or
any condition of the Initial Purchasers' obligations cannot be fulfilled, the
Company and the Operating Partnership agree to reimburse the Initial Purchasers
or such Initial Purchasers as have so terminated this Agreement with respect to
themselves, severally, for all out-of-pocket expenses (including the fees and
expenses of their counsel) reasonably incurred by the Initial Purchasers in
connection with this Agreement or the offering of Securities contemplated
hereunder and the Company and the Operating Partnership shall then be under no
further liability to any Initial Purchasers pursuant to this Agreement except as
provided in Sections 6(m) and 9 of this Agreement.

     13. This Agreement shall inure to the benefit of and be legally binding
upon the Company, the Operating Partnership, the Initial Purchasers, any
controlling persons referred to herein and their respective successors and
assigns. Nothing expressed or mentioned in this Agreement is intended or shall
be construed to give any other person, firm or corporation any legal or
equitable right, remedy or claim under or in respect of this Agreement or any
provision herein contained. No purchaser of Securities from any Initial
Purchaser shall be deemed to be a successor by reason merely of such purchase.

     14. Any action by the Initial Purchasers hereunder may be taken by you
jointly or by the Representatives alone on behalf of the Initial Purchasers, and
any such action taken by you jointly or by the Representatives alone shall be
binding upon the Initial Purchasers. All notices and other communications
hereunder shall be in writing and shall be deemed to have been duly given if
mailed or transmitted by any standard form of telecommunication. Notices to the
Initial Purchasers shall be given to the Initial Purchasers, c/o Chase
