Citigroup Global Markets Inc.
As Representative of the Several Underwriters
c/o Citigroup Global Markets Inc.
388 Greenwich Street
New York, New York  10013

Ladies and Gentlemen:

         Acadia Realty Trust, a self-administered Maryland real estate
investment trust (the "Company") proposes to issue and sell to the firm or firms
named in Schedule A hereto, each as an underwriter (each, an "Underwriter;"
together, the "Underwriters"), an aggregate of 1,890,000 common shares (the
"Primary Securities") of beneficial interests of the Company, par value $.001
per share (the "Common Shares"). In addition, Kenneth F. Bernstein
("Bernstein"), Yale University and The Yale University Retirement Plan for Staff
Employees (together, "Yale," and collectively with Bernstein, the "Selling
Shareholders") propose to sell to the Underwriters an aggregate of 1,110,000
Common Shares (the "Secondary Securities"). The Primary Securities and the
Secondary Securities are collectively called the "Firm Securities." Citigroup
Global Markets Inc. has agreed to act as representative of the several
Underwriters (in such capacity, the "Representative") in connection with the
offering and sale of the Securities. To the extent that there are no additional
Underwriters listed on Schedule A hereto other than you, the term
"Representatives" as used herein shall mean you, as Underwriter, and the terms
"Representatives" and "Underwriters" shall mean either the singular or plural as
the context requires. To the extent that there is only a single Underwriter
listed on Schedule A hereto, then references to the "several" Underwriters shall
be disregarded.

         In addition, the Company and certain of the Selling Shareholders have
granted to the Underwriters an option to purchase up to an additional 450,000
Common Shares, as provided in Section 2 hereof. The additional shares to be sold
pursuant to such option are collectively called the "Optional Securities." The
Firm Securities and, if and to the extent such options are exercised, the
Optional Securities are collectively called the "Securities."

         All of the Company's assets are held by, and all of its operations are
conducted through, Acadia Realty Limited Partnership, a Delaware limited
partnership (the "Partnership"), its majority owned subsidiaries and the joint
ventures in which the Partnership holds a minority






interest. The Company is the sole general partner of the Partnership. For
purposes of this agreement, the term "subsidiaries" shall include the Company's
and the Partnership's minority interests in its joint ventures.

                   SECTION 1. REPRESENTATIONS AND WARRANTIES

         A. Representations and Warranties of the Company and the Partnership.
As of the date hereof, the Company and the Partnership, jointly and severally,
represent, warrant and covenant to each Underwriter as follows:

    (a) Preparation and Filing of Registration Statement. The Company has
prepared and filed with the Securities and Exchange Commission (the
"Commission") (i) a registration statement on Form S-3 (File No. 333-104727),
which contains a prospectus dated May 14, 2003 (the "Issuer Registration
Statement"), (ii) a registration statement on Form S-3 (File No. 333-31630),
which contains a prospectus dated March 29, 2000 (the "Resale Registration
Statement") and (iii) post-effective amendment no. 2 to a registration statement
on Form S-8 (File No. 333-87993) and a re-offer prospectus dated March 19, 2004
(the "Reoffer Registration Statement"), to be used in connection with the public
offering and sale of the Securities. Each of the Issuer Registration Statement,
Reoffer Registration Statement and the Resale Registration Statement, as
amended, including the financial statements, exhibits and schedules thereto, in
the form in which it was declared effective by the Commission under the
Securities Act of 1933, as amended, and the rules and regulations promulgated
thereunder (collectively, the "Securities Act"), all documents incorporated by
reference or deemed to be incorporated by reference therein, including any
information deemed to be a part thereof at the time of effectiveness pursuant to
Rule 430A or Rule 434 under the Securities Act or the Securities Exchange Act of
1934, as amended, and the rules and regulations promulgated thereunder
(collectively, the "Exchange Act") are collectively called the "Registration
Statement." Any registration statement filed by the Company pursuant to Rule
462(b) under the Securities Act is called the "Rule 462(b) Registration
Statement," and from and after the date and time of filing of the Rule 462(b)
Registration Statement the term "Registration Statement" shall include the Rule
462(b) Registration Statement. A prospectus supplement (the "Prospectus
Supplement") setting forth the terms of the offering, the plan of distribution
of the Securities and additional information concerning the Company and its
business and the information concerning the Selling Shareholders has been or
will be so prepared and will be filed pursuant to Rule 424(b) of the Securities
Act on or before the second business day after the date hereof (or such earlier
time as may be required by the Securities Act). The prospectus dated May 14,
2003, the prospectus dated March 29, 2000 and the re-offer prospectus dated
March 19, 2004, collectively with the Prospectus Supplement dated November 4,
2004, in the form first used by the Underwriters to confirm sales of the
Securities, are called the "Prospectus;" provided, however, if the Company has,
with the consent of the Representative, elected to rely upon Rule 434 under the
Securities Act, the term "Prospectus" shall mean the Company's "prospectus
subject to completion" (as defined in Rule 434(g) under the Securities Act) last
provided to the Underwriters by the Company (a "preliminary prospectus") (such
preliminary prospectus is called the "Rule 434 preliminary prospectus").
Notwithstanding the foregoing, if any revised prospectus shall be provided to
the Underwriters by the Company for use in connection with the offering of the
Securities that differs from the prospectus referred to in the immediately
preceding sentence (whether or not such revised prospectus is required to be
filed with the Commission pursuant to Rule 424(b) under the Securities Act), the
term


                                       2



"Prospectus" shall refer to such revised prospectus from and after the time it
is first provided to the Underwriters for such use. All references in this
Agreement to the Registration Statement, the Rule 462(b) Registration Statement,
a preliminary prospectus, or the Prospectus, or any amendments or supplements to
any of the foregoing, shall include any copy thereof filed with the Commission
pursuant to its Electronic Data Gathering, Analysis and Retrieval System
("EDGAR").

         All references in this Agreement to financial statements and schedules
and other information which is "contained," "included," "set forth,"
"described," "disclosed" or "stated" (or words of similar import) in the
Registration Statement or the Prospectus (and all other references of like
import) shall be deemed to mean and include all such financial statements and
schedules and other information which are or are deemed to be incorporated by
reference in the Registration Statement or the Prospectus, as the case may be;
and all references in this Agreement to amendments or supplements to the
Registration Statement or the Prospectus shall be deemed to mean and include the
filing of any document under the Exchange Act which is or is deemed to be
incorporated by reference in the Registration Statement or the Prospectus, as
the case may be.

    (b) Compliance with Registration Requirements. The Resale Registration
Statement was declared effective by the Commission on March 29, 2000, Reoffer
Registration Statement was declared effective by the Commission on March 19,
2004 and the Issuer Registration Statement was declared effective by the
Commission on May 14, 2003. Any Rule 462(b) Registration Statements have been
declared effective by the Commission under the Securities Act. The Securities
all have been duly registered under the Securities Act. The Company has complied
to the Commission's satisfaction with all requests of the Commission for
additional or supplemental information. No stop order suspending the
effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement is in effect and no proceedings for such purpose have been instituted
or are pending or, to the best knowledge of the Company, are contemplated or
threatened by the Commission. The Company and the transactions contemplated by
this Agreement meet the requirements and conditions for use of a registration
statement on Form S-3 under the Securities Act. The Company is eligible to use a
Form S-3 registration statement under the Securities Act pursuant to the
standards for that Form in effect immediately prior to October 21, 1992.

         Each preliminary prospectus, if any, and the Prospectus (and each
document incorporated by reference therein) when filed complied or will comply
in all material respects with disclosure, form and other requirements of the
Securities Act and, if filed by electronic transmission pursuant to EDGAR
(except as may be permitted by Regulation S-T under the Securities Act), the
text thereof (excluding any pictures) was identical or will be identical to the
copy thereof delivered to the Underwriters for use in connection with the offer
and sale of the Securities. Each of the Resale Registration Statement, the
Reoffer Registration Statement, the Issuer Registration Statement, any Rule
462(b) Registration Statement and any post-effective amendment thereto (and each
document incorporated by reference into such registration statements or
post-effective amendment), at the time it became effective and at all subsequent
times up to and on the First Closing Date (as defined below) and on any Second
Closing Date (as defined below), complied and will comply in all material
respects with the disclosure, form and other requirements of the Securities Act
and did not and will not contain any untrue statement of


                                       3



a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein not misleading. The Prospectus (and
each document incorporated by reference therein), as amended or supplemented, as
of its date and at all subsequent times up to and on the First Closing Date (as
defined below) and on any Second Closing Date (as defined below), complied and
will comply in all material respects with the disclosure, form and other
requirements of the Securities Act and did not and will not contain any untrue
statement of a material fact or omit to state a material fact necessary in order
to make the statements therein, in the light of the circumstances under which
they were made, not misleading. The representations and warranties set forth in
this paragraph do not apply to statements in or omissions from the Registration
Statement, any Rule 462(b) Registration Statement, or any post-effective
amendment thereto, or the Prospectus, or any amendments or supplements thereto,
made in reliance upon and in conformity with information relating to any
Underwriter furnished to the Company in writing by the Representative expressly
for use therein. There are no contracts or other documents required to be
described in the Prospectus or the Registration Statement or to be filed as
exhibits to the Registration Statement which have not been described or filed as
required.

    (c) Offering Materials Furnished to Underwriters. The Company has delivered
or will deliver to the Representative one complete manually signed copy of the
Registration Statement and of each consent and certificate of experts filed as a
part thereof and conformed copies of the Registration Statement (without
exhibits) and preliminary prospectuses and the Prospectus, as amended or
supplemented, in such quantities and at such places as the Representative has
reasonably requested for each of the Underwriters.

    (d) Distribution of Offering Material by the Company. The Company has not
distributed and will not distribute, prior to the later of the Second Closing
Date (as defined below) and the completion of the Underwriters' distribution of
the Securities, any offering material in connection with the offering and sale
of the Securities other than a preliminary prospectus, the Prospectus and the
Registration Statement or other materials permitted by the Securities Act.

    (e) The Underwriting Agreement. This Agreement has been duly authorized,
executed and delivered by, and is a valid and binding agreement of, the Company
and the Partnership, enforceable against the Company and the Partnership in
accordance with its terms, except as rights to indemnification hereunder may be
limited by applicable law and except as the enforcement hereof may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws
relating to or affecting the rights and remedies of creditors or by general
equitable principles.

    (f) Authorization of the Securities. The Securities to be purchased by the
Underwriters were duly authorized for issuance and when the Primary Securities
have been delivered and paid for in accordance with this Agreement on the First
Closing Date (as defined below) or the Second Closing Date (as defined below),
as applicable, the Securities will have been validly issued, fully paid and
nonassessable and will have been offered and sold in compliance with all
applicable federal and state securities laws.

    (g) No Applicable Registration or Other Similar Rights. There are no persons
with registration or other similar rights to have any equity or debt securities
registered for sale under the Registration Statement or included in the offering
contemplated by this Agreement, other


                                       4



than the Selling Shareholders with respect to the Secondary Securities included
in the Registration Statement, except for such rights as have been satisfied
under this Agreement or have been duly waived.

    (h) No Material Adverse Change. Except as otherwise disclosed in the
Prospectus, subsequent to the respective dates as of which information is given
in the Prospectus: (i) there has been no material adverse change, or any
development that could reasonably be expected to result in a material adverse
change, in the condition, financial or otherwise, or in the earnings, business,
operations or prospects, whether or not arising from transactions in the
ordinary course of business, of the Company, the Partnership, and their
subsidiaries, considered as one entity (any such change is called a "Material
Adverse Change"); (ii) the Company, the Partnership and their subsidiaries,
considered as one entity, have not incurred any material liability or
obligation, indirect, direct or contingent, not in the ordinary course of
business nor entered into any material transaction or agreement not in the
ordinary course of business; and (iii) there has been no dividend or
distribution of any kind declared, paid or made by the Company or the
Partnership or, except for dividends paid to the Company, the Partnership or
other subsidiaries, any of their subsidiaries on any class of capital stock or
repurchase or redemption by the Company, the Partnership or any of their
subsidiaries of any class of capital stock.

    (i) Independent Accountants. Ernst & Young LLP, who have expressed their
opinion with respect to the financial statements (which term as used in this
Agreement includes the related notes thereto) and supporting schedules filed
with the Commission as a part of the Registration Statement and included in the
Prospectus, are independent registered public accountants as required by the
Securities Act and the Exchange Act.

    (j) Preparation of the Financial Statements. The financial statements filed
with the Commission as a part of the Registration Statement and included in the
Prospectus present fairly the consolidated financial position of the Company and
its subsidiaries as of and at the dates indicated and the results of their
operations and cash flows for the periods specified. The supporting schedules
included in the Registration Statement present fairly the information required
to be stated therein. Such financial statements and supporting schedules comply
as to form with the applicable accounting requirements of the Exchange Act and
the Securities Act and have been prepared in conformity with generally accepted
accounting principles as applied in the United States applied on a consistent
basis throughout the periods involved, except as may be expressly stated in the
related notes thereto. No other financial statements or supporting schedules are
required to be included in the Registration Statement. The financial data
contained in the Prospectus fairly present the information set forth therein on
a basis consistent with that of the audited financial statements contained in
the Registration Statement. Any non-GAAP financial measures, as defined under
Regulation G under the Securities Act, included in the Prospectus are permitted
for use in documents filed with the Commission.

    (k) Organization and Good Standing of the Company, the Partnership and their
Subsidiaries. Each of the Company, the Partnership, and their subsidiaries has
been duly incorporated, formed or organized, as the case may be, and is validly
existing as a corporation, partnership, limited liability company or other legal
entity in good standing under the laws of the jurisdiction of its incorporation,
organization or formation and has full corporate or other power and authority to
own, lease and operate its properties and to conduct its business as described
in


                                       5



the Prospectus and, in the case of the Company and the Partnership, to enter
into and perform their respective obligations under this Agreement. Each of the
Company and each subsidiary is duly qualified as a foreign corporation or other
legal entity to transact business and is in good standing in each jurisdiction
in which such qualification is required, whether by reason of the ownership or
leasing of property or the conduct of business, except for such jurisdictions
where the failure to so qualify or to be in good standing would not,
individually or in the aggregate, result in a Material Adverse Change. All of
the issued and outstanding capital stock, membership interests, partnership
interests or similar equity interests of each subsidiary have been duly
authorized and validly issued, are fully paid and nonassessable and the equity
interests in each subsidiary which are owned by the Company, directly or through
subsidiaries, are free and clear of any security interest, mortgage, pledge,
lien, encumbrance or claim. The Company does not own or control, directly or
indirectly, any corporation, association or other entity other than the
subsidiaries listed on Schedule C attached hereto. There are no subsidiaries,
except for the Partnership, of the Company that meet the definition of
"significant subsidiaries" under Regulation S-X under the Securities Act.

    (l) Capitalization and Other Capital Stock Matters. The authorized, issued
and outstanding capital stock of the Company is as contained in the Prospectus
(other than for subsequent issuances, if any, pursuant to employee benefit plans
described in the Prospectus or upon exercise of outstanding options described in
the Prospectus). The Common Shares (including the Securities) conform in all
material respects to the description thereof contained in the Prospectus. All of
the issued and outstanding Common Shares (including the Common Shares owned by
the Selling Shareholders) have been duly authorized and validly issued, are
fully paid and nonassessable and have been offered, sold and issued in
compliance with federal and state securities laws. All of the issued and
outstanding units of limited partnership interest in the Partnership (the "OP
Units") have been duly authorized by the Partnership. None of the outstanding
Common Shares were issued in violation of any preemptive rights, rights of first
refusal or other similar rights to subscribe for or purchase securities of the
Company and the holders of outstanding shares of capital stock of the Company
are not entitled to preemptive or other rights to subscribe for the Securities.
There are no authorized or outstanding options, warrants, preemptive rights,
rights of first refusal or other rights to purchase, or equity or debt
securities convertible into or exchangeable or exercisable for, any capital
stock or ownership interests in the Company or any of its subsidiaries other
than those accurately described in the Prospectus. The description of the
Company's stock option, stock bonus and other stock plans or arrangements, and
the options or other rights granted thereunder, set forth in the Prospectus
accurately and fairly presents the information required to be shown with respect
to such plans, arrangements, options and rights.

    (m) Stock Exchange Listing. On the First Closing Date and the Second Closing
Date, the Securities will be duly listed and admitted and authorized for trading
on the New York Stock Exchange.

    (n) Non-Contravention of Existing Instruments; No Further Authorizations or
Approvals Required. Neither the Company, the Partnership nor any of their
subsidiaries is in violation of its respective charter, declaration of trust,
by-laws, certificate of formation, partnership agreement, operating agreement or
similar documents or is in default (or, with the giving of notice or lapse of
time, would be in default) ("Default") under any indenture, mortgage, loan or
credit


                                       6



agreement, note, contract, franchise, lease or other agreement, obligation,
condition, covenant or instrument to which the Company, the Partnership or any
of their subsidiaries is a party or by which it or any of them may be bound, or
to which any of the property or assets of the Company, the Partnership or any of
their subsidiaries is subject (each, an "Existing Instrument"), except for such
Defaults as would not, individually or in the aggregate, result in a Material
Adverse Change. The Company's and the Partnership's execution, delivery and
performance of this Agreement and consummation of the transactions contemplated
hereby and by the Prospectus (i) will not result in any violation of the
provisions of the respective charter, declaration of trust, by-laws, certificate
of formation, partnership agreement, operating agreement or similar documents of
the Company, the Partnership or any subsidiary, (ii) will not conflict with or
constitute a breach of, or Default or a Debt Repayment Triggering Event (as
defined below) under, or result in the creation or imposition of any lien,
charge or encumbrance upon any property or assets of the Company, the
Partnership or any of their subsidiaries pursuant to, or require the consent of
any other party to, any Existing Instrument, except for such conflicts,
breaches, Defaults, Debt Repayment Triggering Events (as defined below), liens,
charges or encumbrances as would not, individually or in the aggregate, result
in a Material Adverse Change and (iii) will not result in any violation of any
law, statute, rule, regulation, judgment, order or decree, administrative
regulation or administrative or court decree applicable to the Company, the
Partnership or any subsidiary or any of its or their property. No consent,
approval, authorization or other order of, or registration or filing with, any
court or other governmental or regulatory authority or agency, is required for
the Company or the Partnership's execution, delivery and performance of this
Agreement and consummation of the transactions contemplated hereby and by the
Prospectus, except such as have been obtained or made by the Company and the
Partnership and are in full force and effect under the Securities Act,
applicable state securities or blue sky laws of any jurisdiction in connection
with the purchase and distribution of Securities in the manner contemplated
hereby and in the Prospectus. As used herein, a "Debt Repayment Triggering
Event" means any event or condition which gives, or with the giving of notice or
lapse of time would give, the holder of any note, debenture or other evidence of
indebtedness (or any person acting on such holder's behalf) the right to require
the repurchase, redemption or repayment of all or a portion of such indebtedness
by the Company, the Partnership or any of its subsidiaries.

    (o) No Material Actions or Proceedings. Except as otherwise disclosed in the
Prospectus, there are no legal or governmental actions, suits, investigations or
proceedings pending or, to the best of the Company's or the Partnership's
knowledge, threatened (i) against or affecting the Company, the Partnership or
any of their subsidiaries, (ii) which has as the subject thereof any officer or
trustee of, or property owned or leased by, the Company, the Partnership or any
of their subsidiaries or (iii) relating to environmental or discrimination
matters, which would reasonably be expected to result in a Material Adverse
Change or adversely affect the consummation of the transactions contemplated by
this Agreement. No material labor dispute with the employees of the Company, the
Partnership or any of their subsidiaries exists or, to the best of the Company's
and the Partnership's knowledge, is threatened or imminent and the Company and
Partnership is not aware of any existing or imminent labor disturbance by the
employees at any of its or its subsidiaries' principal suppliers, contractors or
customers that could result in a Material Adverse Change.


                                       7



    (p) Intellectual Property Rights. The Company, the Partnership and their
subsidiaries own or possess sufficient trademarks, trade names, patent rights,
copyrights, domain names, licenses, approvals, trade secrets and other similar
rights (collectively, "Intellectual Property Rights") reasonably necessary to
conduct their businesses as now conducted or as proposed to be conducted in the
Prospectus, and the expected expiration of any of such Intellectual Property
Rights would not result in a Material Adverse Change. Neither the Company, the
Partnership, nor any of their subsidiaries has received any notice of
infringement or conflict with asserted Intellectual Property Rights of others,
which infringement or conflict, if the subject of an unfavorable decision, would
result in a Material Adverse Change. The Company and the Partnership are not
parties to or bound by any options, licenses or agreements with respect to the
Intellectual Property Rights of any other person or entity that are required to
be set forth in the Prospectus and are not described in all material respects.
None of the technology employed by the Company or the Partnership has been
obtained or is being used by the Company or the Partnership in violation of any
contractual obligation binding on the Company, the Partnership or, to the
Company or Partnership's knowledge, any of their officers, trustees or employees
or is otherwise in violation of the rights of any persons, except for violations
which would not, individually or in the aggregate, result in a Material Adverse
Change.

    (q) All Necessary Permits, etc. The Company, the Partnership and each
subsidiary possess such valid and current certificates, authorizations, licenses
or permits issued by the appropriate state, federal or foreign regulatory
agencies or bodies necessary to conduct their respective businesses, except
where the failure to possess such certificate, authorizations or permits would
not, individually or in the aggregate, result in a Material Adverse Change, and
neither the Company, the Partnership nor any subsidiary has received any notice
of proceedings relating to the revocation or modification of, or non-compliance
with, any such certificate, authorization, license or permit which, singly or in
the aggregate, if the subject of an unfavorable decision, ruling or finding,
could result in a Material Adverse Change.

    (r) Title to Properties. Each of the Company, the Partnership and each of
their subsidiaries owns or leases all such properties as are necessary to the
conduct of their respective operations as presently conducted. The Company, the
Partnership and each of their subsidiaries has good and marketable title to all
the properties and assets reflected as owned in the Company's consolidated
financial statements (and schedules thereto) or elsewhere in the Prospectus, in
each case free and clear of any security interests, mortgages, liens,
encumbrances, equities, claims and other defects, except where the existence of
any security interest, mortgage, lien, encumbrance, equity, claim or other
defect would not, individually or in the aggregate, result in a Material Adverse
Change. The real property, improvements, equipment and personal property held
under lease by the Company, the Partnership or any subsidiary are held under
valid and enforceable leases, except where the invalidity or unenforceability of
any leases would not, individually or in the aggregate, result in a Material
Adverse Change.


                                       8



    (s) Tax Law Compliance. The Company, the Partnership and their subsidiaries
have filed all necessary federal, state, local and foreign income and franchise
tax returns or have properly requested extensions thereof and have paid all
taxes required to be paid by any of them and, if due and payable, any related or
similar assessment, fine or penalty levied against any of them except as may be
being contested in good faith and by appropriate proceedings. To the knowledge
of the Company, there is no tax deficiency likely to be asserted against the
Company, the Partnership or any of their subsidiaries. All tax liabilities, if
any, of the Company, the Partnership and their subsidiaries are adequately
provided for on the respective books of the entities.

    (t) Qualification as a Real Estate Investment Trust. The Company has met the
requirements for qualification and taxation as a real estate investment trust
("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"), as of
the close of every taxable year during the Company's existence, and the
Company's current and proposed method of operation will enable it to continue to
meet the requirements for qualification and taxation as a real estate investment
trust for federal income tax purposes.

    (u) Partnership Qualification. Each of the Partnership and any subsidiary
limited liability company or partnership is qualified as a partnership or a
disregarded entity for federal income tax purposes and not as an association
taxable as a corporation or as a publicly traded partnership.

    (v) Company Not an "Investment Company." Each of the Company and the
Partnership are not, and after the sale of the Securities will not be, an
"investment company" or a company "controlled" by an "investment company" within
the meaning of the Investment Company Act of 1940, as amended (the "Investment
Company Act") and will conduct its business in a manner so that it will not
become subject to the Investment Company Act.

    (w) Insurance. Each of the Company, the Partnership and their subsidiaries
are insured by recognized, financially sound and reputable institutions with
policies in such amounts and with such deductibles and covering such risks as
are prudent and customary for their respective businesses including, but not
limited to, policies covering real and personal property owned or leased by the
Company, the Partnership and their subsidiaries against theft, damage,
destruction, acts of vandalism and all other risks customarily insured against.
All such policies of insurance are in full force and effect. There are no claims
by the Company, the Partnership or any of their subsidiaries under any such
policy or instrument as to which any insurance company is denying liability or
defending under a reservation of rights clause, except where such denial or
defense would not, individually or in the aggregate, result in a Material
Adverse Change. Neither the Company, the Partnership nor any subsidiary has been
refused insurance coverage sought or applied for and neither the Company, the
Partnership nor any subsidiary has reason to believe that it or any subsidiary
will not be able (i) to renew its existing insurance coverage as and when such
policies expire or (ii) to obtain comparable coverage from similar institutions
as may be necessary or appropriate to conduct its business as now conducted and
at a cost that would not result in a Material Adverse Change.

    (x) No Price Stabilization or Manipulation. The Company and the Partnership
have not taken and will not take, directly or indirectly, any action designed to
or that might be reasonably


                                       9



expected to cause or result in, under the Exchange Act or otherwise,
stabilization or manipulation of the price of any security of the Company to
facilitate resale of the Securities. The Company acknowledges that the
Underwriters may engage in passive market making transactions in the Securities
in accordance with Regulation M under the Exchange Act.

    (y) Exchange Act Compliance. The documents incorporated or deemed to be
incorporated by reference in the Prospectus, at the time they were or hereafter
are filed with the Commission, complied and will comply in all material respects
with the disclosure, form and other requirements of the Exchange Act, and, when
read together with the other information in the Prospectus, at the time the
Registration Statement and any amendments thereto become effective and at the
First Closing Date and the Second Closing Date, as the case may be, will not
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the fact required to be
stated therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

    (z) No Unlawful Contributions or Other Payments. Neither the Company, the
Partnership nor any of their subsidiaries nor, to the knowledge of the Company
or the Partnership, any trustee, officer, agent, employee or affiliate of the
Company, the Partnership or any of their subsidiaries is aware of or has taken
any action, directly or indirectly, that would result in a violation of such
persons of the FCPA, including, without limitation, making use of the mails or
any means or instrumentality of interstate commerce corruptly in furtherance of
an offer, payment, promise to pay or authorization of the payment of any money,
or other property, gift, promise to give, or authorization of the giving of
anything of value to any "foreign official" (as such term is defined in the
FCPA) or any foreign political party or official thereof or any candidate for
foreign political office, in contravention of the FCPA and the Company, the
Partnership, their subsidiaries and, to the knowledge of the Company and the
Partnership, their affiliates have conducted their businesses in compliance with
the FCPA and have instituted and maintain policies and procedures designed to
ensure, and which are reasonably expected to continue to ensure, continued
compliance therewith. "FCPA" means Foreign Corrupt Practices Act of 1977, as
amended, and the rules and regulations thereunder.

    (aa) Company's Accounting System. The Company has implemented controls and
other procedures that are designed to ensure that information required to be
disclosed by the Company in the reports that it files or submits under the
Exchange Act is recorded, processed, summarized and reported, within the time
periods specified in the Commission's rules and forms and is accumulated and
communicated to the Company's executive management as appropriate to allow
timely decisions regarding required disclosure. The Company makes and keeps
books, records, and accounts, which accurately and fairly reflect in reasonable
detail the transactions and dispositions of the assets of the Company. The
Company, the Partnership and each of their subsidiaries maintain a system of
internal accounting controls sufficient to provide reasonable assurances that
(i) transactions are executed in accordance with management's general or
specific authorization; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles as applied in the United States and to maintain
accountability for assets; (iii) access to assets is permitted only in

    (bb) Compliance with Environmental Laws. Except as (x) otherwise described
in the Prospectus or (y) would not, individually or in the aggregate, result in
a Material Adverse Change (i) neither the Company, the Partnership, nor any of
their subsidiaries is in violation of any federal, state, local or foreign law
or regulation relating to pollution or protection of human health or the
environment (including, without limitation, ambient air, surface water,
groundwater, land surface or subsurface strata) or wildlife, including without
limitation, laws and regulations relating to emissions, discharges, releases or
threatened releases of chemicals, pollutants, contaminants, wastes, toxic
substances, hazardous substances, petroleum and petroleum products
(collectively, "Materials of Environmental Concern"), or otherwise relating to
the manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of Materials of Environmental Concern (collectively,
"Environmental Laws"), which violation includes, but is not limited to,
noncompliance with any permits or other governmental authorizations required for
the operation of the business of the Company, the Partnership or their
subsidiaries under applicable Environmental Laws, or noncompliance with the
terms and conditions thereof, nor has the Company, the Partnership or any of
their subsidiaries received any written communication, whether from a
governmental authority, citizens group, employee or otherwise, that alleges that
the Company, the Partnership or any of their subsidiaries is in violation of any
Environmental Law; (ii) there is no claim, action or cause of action filed with
a court or governmental authority, no investigation with respect to which the
Company or the Partnership has received written notice, and no written notice by
any person or entity alleging potential liability for investigatory costs,
cleanup costs, governmental responses costs, natural resources damages, property
damages, personal injuries, attorneys' fees or penalties arising out of, based
on or resulting from the presence, or release into the environment, of any
Materials of Environmental Concern at any location owned, leased or operated by
the Company, the Partnership or any of their subsidiaries, now or in the past
(collectively, "Environmental Claims"), pending or, to the best of the Company's
and the Partnership's knowledge, threatened against the Company, the Partnership
or any of their subsidiaries or any person or entity whose liability for any
Environmental Claim the Company, the Partnership or any of their subsidiaries
has retained or assumed either contractually or by operation of law; and (iii)
to the Company's and the Partnership's knowledge, there are no past or present
actions, activities, circumstances, conditions, events or incidents, including,
without limitation, the release, emission, discharge, presence or disposal of
any Materials of Environmental Concern, that reasonably could result in a
violation of any Environmental Law or form the basis of a potential
Environmental Claim against the Company, the Partnership or any of their
subsidiaries or against any person or entity whose liability for any
Environmental Claim the Company, the Partnership, or any of their subsidiaries
has retained or assumed either contractually or by operation of law. Except as
set forth in the Prospectus, neither the Company, the Partnership nor any
subsidiary has been named as a "potentially responsible party" under the
Comprehensive Environmental Responses Compensation and Liability Act of 1980, as
amended.

    (cc) Periodic Review of Costs of Environmental Compliance. In the ordinary
course of its business, the Company and the Partnership conduct a periodic
review of the effect of Environmental Laws on the business, operations and
properties of the Company, the Partnership and their subsidiaries, in the course
of which it identifies and evaluates associated costs and liabilities
(including, without limitation, any capital or operating expenditures required
for clean-up, closure of properties or compliance with Environmental Laws or any
permit, license or approval, any related constraints on operating activities and
any potential liabilities to third


                                       11



parties). On the basis of such review and the amount of its established
reserves, the Company and the Partnership have reasonably concluded that such
associated costs and liabilities would not, individually or in the aggregate,
result in a Material Adverse Change.

    (dd) ERISA Compliance. The Company, the Partnership and their subsidiaries
and any "employee benefit plan" (as defined under the Employee Retirement Income
Security Act of 1974, as amended, and the regulations and published
interpretations thereunder (collectively, "ERISA")) established or maintained by
the Company, the Partnership and their subsidiaries or their "ERISA Affiliates"
(as defined below) are in compliance in all material respects with ERISA. "ERISA
Affiliate" means, with respect to the Company, the Partnership or a subsidiary,
any member of any group of organizations described in Sections 414(b), (c), (m)
or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and
published interpretations thereunder (the "Code"), of which the Company, the
Partnership or such subsidiary is a member. No "reportable event" (as defined
under ERISA) has occurred or is reasonably expected to occur with respect to any
"employee benefit plan" established or maintained by the Company, the
Partnership, their subsidiaries or any of their ERISA Affiliates. No "employee
benefit plan" established or maintained by the Company, the Partnership, their
subsidiaries or any of their ERISA Affiliates, if such "employee benefit plan"
were terminated, would have any "amount of unfunded benefit liabilities" (as
defined under ERISA). Neither the Company, the Partnership, their subsidiaries
nor any of their ERISA Affiliates has incurred or reasonably expects to incur
any liability under (i) Title IV of ERISA with respect to termination of, or
withdrawal from, any "employee benefit plan" or (ii) Sections 412, 4971, 4975 or
4980B of the Code. Each "employee benefit plan" established or maintained by the
Company, the Partnership, their subsidiaries or any of their ERISA Affiliates
that is intended to be qualified under Section 401(a) of the Code is so
qualified and nothing has occurred, whether by action or failure to act, which
would cause the loss of such qualification.

    (ee) Brokers. Except as disclosed in the Prospectus, there is no broker,
finder or other party that is entitled to receive from the Company, the
Partnership or, to the knowledge of the Company or the Partnership, the Selling
Shareholders, any brokerage or finder's fee or other fee or commission as a
result of any transactions contemplated by this Agreement.

    (ff) No Outstanding Loans or Other Indebtedness. There are no outstanding
loans, advances (except normal advances for business expenses in the ordinary
course of business) or guarantees or indebtedness by the Company, the
Partnership or any of their subsidiaries to or for the benefit of any of the
officers or trustees of the Company or any of their family members, except as
disclosed in the Prospectus.

    (gg) Compliance with Laws. The Company and the Partnership have not been
advised, and have no reason to believe, that they and each of their subsidiaries
are not conducting business in compliance with all applicable laws, rules and
regulations of the jurisdictions in which it is conducting business, except
where failure to be so in compliance would not result in a Material Adverse
Change.

    (hh) Transfer Taxes. There are no transfer taxes or other similar fees or
charges under federal law or the laws of any state, or any political subdivision
thereof, required to be paid in


                                       12



connection with the execution and delivery of this Agreement or the transfer by
the Company or the Selling Shareholders of the related Securities.

    (ii) Dividends and Loans. No subsidiary of the Company is currently
prohibited, directly or indirectly, from paying any dividends to the Company,
from making any other distribution on such subsidiary's capital stock, from
repaying to the Company any loans or advances to such subsidiary from the
Company or from transferring any of such subsidiary's property or assets to the
Company or any other subsidiary of the Company, except as described in or
contemplated by the Prospectus.

    (jj) Sarbanes-Oxley; NYSE Listing Standards. There is and has been no
failure on the part of the Company and any of the Company's trustees or
officers, in their capacities as such, to comply with any provision of the
Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in
connection therewith (the "Sarbanes-Oxley Act"), including Section 402 of the
Sarbanes-Oxley Act related to loans and Sections 302 and 906 thereof related to
certifications. The Company is in compliance with the current listing standards
of the New York Stock Exchange.

    (kk) Recordkeeping and Reporting. The operations of the Company, the
Partnership and their subsidiaries are and have been conducted at all times in
compliance with applicable financial recordkeeping and reporting requirements of
the Currency and Foreign Transactions Reporting Act of 1970, as amended, the
money laundering statutes of all jurisdictions, the rules and regulations
thereunder and any related or similar rules, regulations or guidelines, issued,
administered or enforced by any governmental agency (collectively, the "Money
Laundering Laws") and no action, suit or proceeding by or before any court or
governmental agency, authority or body or any arbitrator involving the Company,
the Partnership or any of their subsidiaries with respect to the Money
Laundering Laws is pending or, to the best knowledge of the Company or the
Partnership threatened.

    (ll) Treasury Department Sanctions. Neither the Company, the Partnership nor
any of their subsidiaries nor, to the knowledge of the Company, the Partnership,
any trustee, officer, agent, employee or affiliate of the Company or Partnership
or any of their subsidiaries is currently subject to any U.S. sanctions
administered by the Office of Foreign Assets Control of the U.S. Treasury
Department.

    (mm) Partnership Agreement. The limited partnership agreement of the
Partnership, including any amendments thereto, has been duly and validly
authorized, executed and delivered by the Company and, to the best knowledge of
the Company, all the partners of the Partnership and constitutes a valid and
binding agreement, enforceable in accordance with its terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting creditors' rights generally or by general principles of equity.

November 4, 2004, between


                                       13

and delivered by or on behalf of such Selling Shareholder and are valid and
binding agreements of such Selling Shareholder, enforceable in accordance with
their respective terms, except as rights to indemnification or contribution
hereunder may be limited by applicable law and except as the enforcement hereof
or thereof may be limited by bankruptcy, insolvency, reorganization, moratorium
or other similar laws relating to or affecting the rights and remedies of
creditors or by general equitable principles.

    (b) Title to Secondary Securities to be Sold; All Authorizations Obtained.
On the First Closing Date (as defined below) and the Second Closing Date (as
defined below), such Selling Shareholder will have good and marketable title to
all of the Secondary Securities which may be sold by such Selling Shareholder
pursuant to this Agreement on such date free and clear of all security
interests, claims, liens, equities or other encumbrances and the legal right and
power (other than as provided for in the Custody Agreement), and all
authorizations and approvals required by law and under its organizational
documents, if applicable, to enter into this Agreement, the Custody Agreement
and the Power of Attorney, to sell, transfer and deliver all of the Secondary
Securities which may be sold by such Selling Shareholder pursuant to this

Company's Declaration of Trust, By-laws and applicable law and as required by
Section 8-401 of the Uniform Commercial Code as in effect in the State of New
York (the "UCC") and an indication from DTC by book entry that in the case of
each Underwriter, the Secondary Securities being purchased by or on behalf of
such Underwriter have been credited to "securities accounts" (as defined in
Section 8-501 of the UCC) of such Underwriter with DTC (assuming that neither
DTC nor any such Underwriter has notice of any adverse claim (as such phrase is
defined in Section 8-105 of the UCC) to such Secondary Securities), (i) DTC
shall be a "protected purchaser" of such Secondary Securities within the meaning
of Section 8-303 of the Uniform Commercial Code ("UCC"), and (ii) under Section
8-501 of the UCC, each Underwriter will acquire a valid "security entitlement"
(as defined in Section 8-102 of the UCC) to the Secondary Securities being so
purchased by or on behalf of such Underwriter, and, to the extent governed by
the UCC, no action based on any "adverse claim" (as defined in Section 8-102 of

may assume that when such payment, delivery, registration and crediting occur,
(x) Cede or such other nominee is not a "securities intermediary" (as defined in

such Secondary Securities in the name of DTC for purposes of Section 8-106(b)(2)
of the UCC, and (z) DTC is a "clearing corporation" (as defined in Section 8-102
of the UCC).

    (d) Non-Contravention; No Further Authorizations or Approvals Required. The
execution and delivery by such Selling Shareholder of, and the performance by
such Selling Shareholder of its obligations under, this Agreement, the Custody
Agreement or the Power of Attorney will not contravene or conflict with, result
in a breach of, or constitute a Default under, or require the consent of any
other party to, the organizational documents of such Selling Shareholder or any
other agreement or instrument to which such Selling Shareholder is a party or by
which it is bound or under which it is entitled to any right or benefit, any
provision of applicable law or any judgment, order, decree or regulation
applicable to such Selling Shareholder of any court, regulatory body,

this Agreement or the consummation by such Selling Shareholder of any of the
other transactions contemplated hereunder or under the Custody Agreement or the
Power of Attorney.

            SECTION 2. PURCHASE, SALE AND DELIVERY OF THE SECURITIES

    (a) The Securities. Upon the terms herein set forth, the Company agrees to
sell to the several Underwriters an aggregate of 1,890,000 Primary Securities
and the Selling Shareholders agree to sell to the several Underwriters an
aggregate of 1,110,000 Secondary Securities, each Selling Shareholder selling
the number of Secondary Securities set forth opposite such Selling Shareholder's
name on Schedule B. On the basis of the representations, warranties and
agreements herein contained, and upon the terms but subject to the conditions
herein set forth, the Underwriters agree, severally and not jointly, to purchase
from the Company and the Selling Shareholders the respective number of Firm
Securities set forth opposite their names on Schedule B. The purchase price per
Common Share to be paid by the several Underwriters to the Company and the
Selling Shareholders shall be $15.08 per share.

    (b) The First Closing Date. Delivery of certificates for the Securities to
be purchased by the Underwriters and payment therefor shall be made at the
offices of the Representative, 388 Greenwich Street, New York, New York 10013
(or such other place as may be agreed to by the Company and the Representative)
at 9:00 a.m. New York time, on November 10, 2004, or such other time and date
not later than 12:30 p.m. New York time, on December 3, 2004, as the
Representative shall designate by written notice to the Company (the time and
date of such closing are called the "First Closing Date"). The Company and the
Selling Shareholders hereby acknowledge that circumstances under which the
Representative may provide notice to postpone the First Closing Date as
originally scheduled include, but are in no way limited to, any determination by
the Company, the Selling Shareholders or the Representative to recirculate to
the public copies of an amended or supplemented Prospectus or a delay as
contemplated by the provisions of Section 9 hereof.

    (c) The Optional Securities; the Second Closing Date. In addition, on the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Company and
Yale hereby grant an option to the several Underwriters to purchase, severally
and not jointly, up to an aggregate of 450,000 Optional Securities from the
Company at the purchase price per share to be paid by the Underwriters for the
Firm Securities. The option granted hereunder is for use by the Underwriters
solely in covering any over-allotments in connection with the sale and
distribution of the Firm Securities. The option granted hereunder may be
exercised at any time, from time to time, upon written notice by the
Representative to the Company and Yale, which notices may be given at any time
within 30 days from the date of this Agreement. Such notice shall set forth (i)
the aggregate number of Optional Securities as to which the Underwriters are
exercising the option, (ii) the names and denominations in which the
certificates for the Optional Securities are to be registered and (iii) the
time, date and place at which such certificates will be delivered (which time
and date may be simultaneous with, but not earlier than, the First Closing Date;
and in such case the term "First Closing Date" shall refer to the time and date
of delivery of certificates for the Firm Securities and the Optional
Securities). Such time and date of delivery, if subsequent to the First Closing
Date, is called the "Second Closing Date" and shall be determined by the
Representative and shall not be earlier than three (3) nor later than five (5)
full Business Days (any day, other


                                       17



than a Saturday, Sunday or legal holiday in the State of New York, on which
banks are open for business in New York City) after delivery of such notice of
exercise. If any Optional Securities are to be purchased, (a) each Underwriter
agrees, severally and not jointly, to purchase the number of Optional Securities
(subject to such adjustments to eliminate fractional shares as the
Representative may determine) that bears the same proportion to the total number
of Optional Securities to be purchased as the number of Firm Securities set
forth on Schedule A opposite the name of such Underwriter bears to the total
number of Firm Securities and (b) each Selling Shareholder, as applicable,
agrees, severally and not jointly, to sell the number of Optional Securities
(subject to such adjustments to eliminate fractional shares as the
Representative may determine) that bears the same proportion to the total number
of Optional Securities to be sold as the number of Optional Securities set forth
in Schedule B opposite the name of such Selling Stockholder bears to the total
number of Optional Securities. The Representative may cancel the option at any
time prior to its expiration by giving written notice of such cancellation to
the Company and Yale.

    (d) Public Offering of the Securities. The Representative hereby advises the
Company and the Selling Shareholders that the Underwriters intend to offer for
sale to the public, as described in the Prospectus, their respective portions of
the Securities as soon after this Agreement has been executed as the
Representative, in their sole judgment, has determined is advisable and
practicable.

    (e) Payment for the Securities. Payment for the Securities to be sold by the
Company and the Selling Shareholders shall be made at the First Closing Date
(and, if the Underwriters exercise their option to purchase Optional Securities,
at the Second Closing Date) by wire transfer of immediately available funds to
the Company, acting on its own behalf and as custodian for each of the Selling
Shareholders under the respective Custody Agreements, according to instructions
previously provided by the Company to the Representative.

         It is understood that the Representative has been authorized, for its
own account and the accounts of the several Underwriters, to accept delivery of
and receipt for, and make payment of the purchase price for, the Firm Securities
and any Optional Securities the Underwriters have agreed to purchase. The
Representative, individually and not as the Representative of the Underwriters,
may (but shall not be obligated to) make payment for any Securities to be
purchased by any Underwriter whose funds shall not have been received by the
Representative by the First Closing Date or the Second Closing Date, as the case
may be, for the account of such Underwriter, but any such payment shall not
relieve such Underwriter from any of its obligations under this Agreement.

         The Company and each Selling Shareholder hereby agree that each will
pay all stock transfer taxes, stamp duties and other similar taxes, if any,
payable upon the sale or delivery of the Securities to be sold by the respective
party to the several Underwriters, or otherwise in connection with the
performance of the respective party's obligations hereunder.

    (f) Delivery of the Securities. On the First Closing Date, the Company and
the Selling Shareholders shall deliver, or cause to be delivered, a credit
representing the Primary Securities and the Secondary Securities, respectively,
to an account or accounts at The Depository Trust Company as designated by the
Representative for the accounts of the several Underwriters,


                                       18



against the irrevocable release of a wire transfer of immediately available
funds for the amount of the purchase price therefor. On the Second Closing Date,
the Company shall deliver, or cause to be delivered, a credit representing the
Optional Securities to an account or accounts at The Depository Trust Company as
designated by the Representative for the accounts of the several Underwriters,
against the irrevocable release of a wire transfer of immediately available
funds for the amount of the purchase price therefor. Time shall be of the
essence, and delivery on the date and at the place specified in this Agreement
is a further condition to the obligations of the Underwriters.

    (g) Delivery of Prospectus to the Underwriters. Not later than 12:00 p.m. on
the second business day following the date the Firm Securities are first
released by the Underwriters for sale to the public, the Company shall deliver
or cause to be delivered, copies of the Prospectus in such quantities and at
such places as the Representative shall reasonably request.

                        SECTION 3. ADDITIONAL COVENANTS

         A. Covenants of the Company. The Company further covenants and agrees
with each Underwriter as follows:

    (a) Representative's Review of Proposed Amendments and Supplements. During
such period beginning on the date hereof and ending on the later of the First
Closing Date or such date, as in the reasonable and good faith opinion of
counsel for the Underwriters, the Prospectus is no longer required by the
Securities Act to be delivered in connection with sales by an Underwriter or
dealer (the "Prospectus Delivery Period"), prior to amending or supplementing
the Registration Statement (including any Rule 462(b) Registration Statement) or
the Prospectus (including any amendment or supplement through incorporation by
reference of any report filed under the Exchange Act), the Company shall furnish
to the Representative for review a copy of each such proposed amendment or
supplement, and the Company shall not file any such proposed amendment or
supplement to which the Representative reasonably objects in writing.

    (b) Securities Act Compliance. During the Prospectus Delivery Period, the
Company shall promptly advise the Representative in writing (i) of the receipt
of any comments of, or requests for additional or supplemental information from,
the Commission, (ii) of the time and date of any filing of any post-effective
amendment to the Registration Statement or any amendment or supplement to any
preliminary prospectus or the Prospectus, (iii) of the time and date that any
post-effective amendment to the Registration Statement becomes effective and
(iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement or any post-effective amendment
thereto or of any order preventing or suspending the use of any preliminary
prospectus or the Prospectus, or of any proceedings to remove, suspend or
terminate from listing or quotation the Common Shares from any securities
exchange upon which it is listed for trading or included or designated for
quotation, or of the threatening or initiation of any proceedings for any of
such purposes. If the Commission shall enter any such stop order at any time,
the Company will use commercially reasonable efforts to obtain the lifting of
such order at the earliest possible moment. Additionally, the Company agrees
that it shall comply with the provisions of Rules 424(b), 430A and 434, as
applicable, under the Securities Act and will use its reasonable efforts to
confirm that any filings made by the Company under such Rule 424(b) were

Matters. If, during the Prospectus Delivery Period, any event shall occur or

otherwise necessary to amend or supplement the Prospectus to comply with law,
the Company agrees to promptly prepare (subject to Section 3(A)(a) hereof), file

any action that would subject it to general service of process in any such
jurisdiction where it is not presently qualified or where it would be subject to
taxation as a foreign corporation. The Company will advise the Representative
promptly of the suspension of the qualification or registration of (or any such

(including the reasonable fees and disbursements of counsel chosen by the
Representative) as such expenses are reasonably incurred by such Underwriter or
such indemnified person in connection with investigating, defending, settling,
compromising or paying any such loss, claim, damage, liability, expense or
action; provided, however, that each Selling Shareholder shall only be subject
to such liability with respect to subsections (A) and (B) above to the extent

arises in reliance upon and in conformity with written information relating to
such Selling Shareholder furnished by such Selling Shareholder expressly for use
in such documents; and provided, further, that the foregoing indemnity agreement
shall not apply to any loss, claim,


                                       27

of the Underwriters against the Selling Shareholders for breach of contract,
indemnification, reimbursement or advancement of expenses or otherwise pursuant
to subsections (A) or (B) of this Section 7(b) or subsection (C) of this Section
7(b) (but only if, and to the extent that, any Claim brought under subsection

by such Underwriters to be satisfied in full by the Company and shall be
satisfied by the Selling Shareholders only to the extent the Company shall not

Act, or other federal or state statutory law or regulation, or at common law or
otherwise (including in settlement of any litigation, if such settlement is
effected with the written consent of such Underwriter, which consent shall not
be unreasonably withheld), insofar as such loss, claim, damage, liability or
expense (or actions in respect thereof as contemplated below) arises out of or
is based upon any untrue or alleged untrue statement of a material fact
contained in the Registration Statement, any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto), or arises out of or is
based upon the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, in each case to the extent, but only to the extent, that such untrue
statement or alleged untrue statement or omission or alleged omission was made
in the Registration Statement, any preliminary prospectus, or the Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company (or its counsel) by the
Representative (or its counsel) expressly for use therein; and to reimburse the
Company, the Partnership or any such trustee, officer, Selling Shareholder, or
controlling person for any legal and other expense reasonably incurred by the
Company, the Partnership or any such trustee, officer, Selling Shareholder, or
controlling person in connection with investigating, defending, settling,
compromising or paying any such loss, claim, damage, liability, expense or
action. The Company and each of the Selling Shareholders hereby acknowledge that
the only information that the Underwriters have furnished


                                       28



to the Company and the Selling Shareholders expressly for use in the
Registration Statement, any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) are the statements set forth in the last
paragraph of the cover page regarding delivery of the Securities and, in the
section entitled "Underwriting" in the Prospectus; (i) the sentence related to
commission equivalents received from investors and (ii) the paragraphs related
to stabilization and syndicate covering transactions; and the Underwriters
confirm that such statements are correct. The indemnity agreement set forth in
this Section 7(c) shall be in addition to any liabilities that each Underwriter
may otherwise have.

    (d) Notifications and Other Indemnification Procedures. Promptly after
receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise than under
the indemnity agreement contained in this Section 7 to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the indemnifying party and
the indemnified party in conducting the defense of any such action or that there
may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action and approval by the
indemnified party of counsel, the indemnifying party will not be liable to such
indemnified party under this Section 7 for any legal or other expenses
subsequently and reasonably incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with local
counsel), approved by the indemnifying party (the Representative in the case of
Section 7(c) and Section 8), representing the indemnified parties who are
parties to such action) or (ii) the indemnifying party shall not have employed
counsel reasonably satisfactory to the indemnified party to represent the
indemnified party within a reasonable time after notice of commencement of the
action, in each of which cases the reasonable fees and expenses of counsel shall
be at the expense of the indemnifying party.

    (e) Settlements. The indemnifying party under this Section 7 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 party agrees to indemnify the


                                       29



indemnified party against any loss, claim, damage, liability or expense by
reason of such settlement or judgment. Notwithstanding the foregoing sentence,
if at any time an indemnified party shall have requested an indemnifying party
to reimburse the indemnified party for fees and expenses of counsel as
contemplated by Section 7(d) hereof, the indemnifying party 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 party of the aforesaid request and (ii) such indemnifying
party shall not have responded to the aforesaid request or reimbursed the
indemnified party in accordance with such request prior to the date of such
settlement. No indemnifying party shall, without the prior written consent of
the indemnified party (which shall not be unreasonably withheld), effect any
settlement, compromise or consent to the entry of judgment in any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity was or could have been sought
hereunder by such indemnified party, unless such settlement, compromise or
consent includes an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such action, suit or
proceeding.

                            SECTION 8. CONTRIBUTION

         If the indemnification provided for in Section 7 is for any reason held
to be unavailable to or otherwise insufficient to hold harmless an indemnified
party in respect of any losses, claims, damages, liabilities or expenses
referred to therein, then each indemnifying party shall contribute to the
aggregate amount paid or payable by such indemnified party, as incurred, as a
result of any losses, claims, damages, liabilities or expenses referred to
therein (i) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Selling Shareholders, on the one hand,
and the Underwriters, on the other hand, from the offering of the Securities
pursuant to this Agreement or (ii) if the allocation provided by clause (i)
above is not permitted by applicable law, in such proportion as is appropriate
to reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company and the Selling Shareholders, on the one
hand, and the Underwriters, on the other hand, in connection with the statements
or omissions or inaccuracies in the representations and warranties herein which
resulted in such losses, claims, damages, liabilities or expenses, as well as
any other relevant equitable considerations. The relative benefits received by
the Company and the Selling Shareholders, on the one hand, and the Underwriters,
on the other hand, in connection with the offering of the Securities pursuant to
this Agreement shall be deemed to be in the same respective proportions as the
total net proceeds from the offering of the Securities pursuant to this
Agreement (before deducting expenses) received by the Company and the Selling
Shareholders, and the total underwriting discount received by the Underwriters,
in each case as set forth on the front cover page of the Prospectus (or, if Rule
434 under the Securities Act is used, the corresponding location on the Term
Sheet) bear to the aggregate public offering price of the Securities as set
forth on such cover. The relative fault of the Company and the Selling
Shareholders, on the one hand, and the Underwriters, on the other hand, shall be
determined by reference to, among other things, whether any such untrue or
alleged untrue statement of a material fact or omission or alleged omission to
state a material fact or any such inaccurate or alleged inaccurate
representation or warranty relates to information supplied by the Company or the
Selling Shareholders, on the one hand, or the Underwriters, on the other hand,
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.


                                       30



         The amount paid or payable by a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 7(c), any legal or
other fees or expenses reasonably incurred by such party in connection with
investigating or defending any action or claim. The provisions set forth in
Section 7(c) with respect to notice of commencement of any action shall apply if
a claim for contribution is to be made under this Section 8; provided, however,
that no additional notice shall be required with respect to any action for which
notice has been given under Section 7(c) for purposes of indemnification.

         The Company, the Selling Shareholders and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this Section 8
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 8.

         Notwithstanding the provisions of this Section 8, no Underwriter shall
be required to contribute any amount in excess of the underwriting commissions
received by such Underwriter in connection with the Securities underwritten by
it and distributed to the public. 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 Underwriters' obligations to contribute
pursuant to this Section 8 are several, and not joint, in proportion to their
respective underwriting commitments as set forth opposite their names in
Schedule A. The obligations of the Selling Shareholders to contribute pursuant
to this Section 8 are several, and not joint, and in proportion to the gross
proceeds, net of underwriting commissions and discounts, to be received by the
respective Selling Shareholders in respect of the Firm Securities to be sold as
set forth opposite each Selling Shareholder's name in Schedule A. For purposes
of this Section 8, each officer and employee of an Underwriter and each person,
if any, who controls an Underwriter within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act shall have the same rights
to contribution as such Underwriter, and each trustee and officer of the
Company, and each person, if any, who controls the Company with the meaning of
Section 15 of the Securities Act or Section 20(a) of the Exchange Act shall have
the same rights to contribution as the Company. Notwithstanding the foregoing,
no Selling Shareholder shall be obligated to make contributions hereunder which
in the aggregate exceed the amount for which such Selling Shareholder would have
been liable pursuant to Section 7(b) of this Agreement.

         Notwithstanding the provisions of this Section 8, the liability of each
Selling Shareholder under this Section 8 shall be limited to an amount equal to
the gross proceeds, net of underwriting commissions and discounts but before
expenses, to such Selling Shareholder from the sale of their Securities
hereunder.

         SECTION 9. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS

         If, on the First Closing Date or the Second Closing Date, as the case
may be, any one or more of the several Underwriters shall fail or refuse to
purchase Securities that it or they have agreed to purchase hereunder on such
date, and the aggregate number of Securities which such defaulting Underwriter
or Underwriters agreed by failed or refused to purchase does not exceed


                                       31



10% of the aggregate number of the Securities to be purchased on such date, the
other Underwriters shall be obligated, severally, in the proportions that the
number of Securities set forth opposite their respective names on Schedule A
bears to the aggregate number of Securities set forth opposite the names of all
such non-defaulting Underwriters, or in such other proportions as may be
specified by the Representative with the consent of the non-defaulting
Underwriters, to purchase the Securities which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the Underwriters shall fail or refuse to purchase Securities and the
aggregate number of Securities with respect to which such default occurs exceeds
10% of the aggregate number of Securities to be purchased on such date, and
arrangements satisfactory to the Representative and the Company for the purchase
of such Securities are not made within 72 hours after such default, this
Agreement shall terminate without liability of any party (other than the
defaulting Underwriter who shall remain liable for any damages incurred by the
Company, the Selling Shareholder or other Underwriter that are occasioned by its
breach or default hereunder) to any other party except that the provisions of
Section 4, Section 6, Section 7 and Section 8 shall at all times be effective
and shall survive such termination. In any such case, either the Representative
or the Company shall have the right to postpone the First Closing Date or the
Second Closing Date, as the case may be, but in no event for longer than seven
days in order that the required changes, if any, to the Registration Statement
and the Prospectus or any other documents or arrangements may be effected.

         As used in this Agreement, the term "Underwriter" shall be deemed to
include any person substituted for a defaulting Underwriter under this Section
9. Any action taken under this Section 9 shall not relieve any defaulting
Underwriter from liability in respect of any default of such Underwriter under
this Agreement.

         SECTION 10. FAILURE OF THE SELLING SHAREHOLDER OR THE COMPANY
                       TO SELL AND DELIVER COMMON SHARES

         If, on the First Closing Date, any Selling Shareholder shall fail to
sell and deliver to the Underwriters the Secondary Securities pursuant to this
Agreement, then the Underwriters may at their option purchase the Securities
which the Company and the other Selling Shareholders have agreed to sell and
deliver in accordance with the terms hereof or, by written notice from the
Representative to the Company and the Selling Shareholder, may postpone the
First Closing Date or the Second Closing Date, as the case may be, but in no
event for longer than seven days in order that the required changes, if any, to
the Registration Statement and the Prospectus or any other documents or
arrangements may be effected. No action taken pursuant to this Section 10 shall
relieve the Selling Shareholder so defaulting from liability, if any, in respect
of such default. If, on the First Closing Date, the Company shall fail to sell
and deliver to the Underwriters the Primary Securities pursuant to this
Agreement, then this Agreement shall terminate without any liability on the part
of any non-defaulting party; provided, however, that the provisions of Section
1, 4, 6 and 12 shall remain in full force and effect. No action taken pursuant
to this Section 10 shall relieve the Company so defaulting from liability, if
any, in respect of such default.


                                       32



                   SECTION 11. TERMINATION OF THIS AGREEMENT

         Prior to the First Closing Date, this Agreement may be terminated by
the Representative by written notice given to the Company and the Selling
Shareholders if at any time since the date hereof (i) trading or quotation of
the Common Shares shall have been suspended or limited by the Commission or by
the New York Stock Exchange, or trading in securities generally on the New York
Stock Exchange shall have been suspended or limited, or minimum or maximum
prices shall have been generally established on such exchange; (ii) a general
banking moratorium shall have been declared by any of federal or New York State
authorities; (iii) there shall have occurred any outbreak or escalation of
national or international hostilities or any crisis or calamity, or any change
in the United States or international financial markets, as in the judgment of
the Representative is material and adverse and makes it impracticable to proceed
with the offering or the delivery of the Securities in the manner and on the
terms described in the Prospectus. Any termination pursuant to this Section 11
shall be without liability on the part of (a) the Company or the Selling
Shareholders to any Underwriter, except that the Company and the Selling
Shareholders shall be obligated to reimburse the expenses of the Representative
and the Underwriters as provided for in Sections 4 and 6 hereof, (b) any
Underwriter to the Company or the Selling Shareholders, or (c) of any party
hereto to any other party except that the provisions of Section 7 and Section 8
shall at all times be effective and shall survive such termination.

        SECTION 12. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY

         The respective indemnities, agreements, representations, warranties and
other statements of the Company, of its officers, of the Partnership, of the
Selling Shareholders and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of any Underwriter or the Company or the
Partnership or any of its or their partners, officers, trustees or directors or
any controlling person or the Selling Shareholders, as the case may be, and will
survive delivery of and payment for the Securities sold hereunder and any
termination of this Agreement; provided, however, that the covenant of the
Selling Shareholders in Section 3(B)(a) hereof shall not survive any such
termination of the Agreement or failure of the Secondary Securities to have been
purchased and sold by the Closing Date.

                                       35



                         SECTION 17. GENERAL PROVISIONS

         This Agreement constitutes the entire agreement of the parties to this
Agreement and supersedes all prior written or oral and all contemporaneous oral
agreements, understandings and negotiations with respect to the subject matter
hereof. This Agreement may be executed in two or more counterparts, each one of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument. This Agreement may not be amended or
modified unless in writing by all of the parties hereto, and no condition herein
(express or implied) may be waived unless waived in writing by each party whom
the condition is meant to benefit. The Section headings herein are for the
convenience of the parties only and shall not affect the construction or
interpretation of this Agreement.

         Each of the parties hereto acknowledges that it is a sophisticated
business person who was adequately represented by counsel during negotiations
regarding the provisions hereof, including, without limitation, the
indemnification provisions of Section 7 hereof and the contribution provisions
of Section 8 hereof, and is fully informed regarding said provisions. Each of
the parties hereto further acknowledges that the provisions of Sections 7 and 8
hereof fairly allocate the risks in light of the ability of the parties to
investigate the Company, its affairs and its business in order to assure that
adequate disclosure has been made in the Registration Statement, any preliminary
prospectus and the Prospectus (and any amendments and supplements thereto), as
required by the Securities Act and the Exchange Act.

         The respective indemnities, contribution agreements, representations,
warranties and other statements of the Company, the Partnership, the Selling
Shareholders and the several Underwriters set forth in or made pursuant to this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation, or statement as to the results thereof, made by or on behalf
of any Underwriter, the officers or employees of any Underwriter, any person
controlling any Underwriter, the Partnership, the Company, the officers or
employees of the Company, or any person controlling the Company, any Selling
Shareholder or any person controlling such Selling Shareholder, (ii) acceptance
of the Securities and payment for them hereunder and (iii) termination of this
Agreement.

         Except as otherwise provided, this Agreement has been and is made
solely for the benefit of and shall be binding upon the Company, the
Partnership, the Selling Shareholders, the Underwriters, the Underwriters'
officers and employees, any controlling persons referred to herein, the
Company's trustees and the Company's officers and their respective successors
and assigns, all as and to the extent provided in this Agreement, and no other
person shall acquire or have any right under or by virtue of this Agreement. The
term "successors and assigns" shall not include a purchaser of any of the
Securities from any of the several Underwriters merely because of such purchase.

agreement, kindly sign and return to the Company the enclosed copies hereof,

to the Representative at the request of the Company and shall so state therein.
References to the Prospectus in this [Exhibit B] include any supplements thereto

             (i) The  Underwriting  Agreement,  dated  November  ___,  2004 (the
    "Underwriting   Agreement")   and  the  Custody   Agreement   (the  "Custody
    Agreement") and the Powers of Attorney (the "Power of Attorney"), each dated
    November  ___, 2004 and executed by the Selling  Shareholder  have been duly
    authorized,  executed  and  delivered  by or on behalf of, and are valid and
    legally  binding  agreements  of, the Selling  Shareholder,  enforceable  in
    accordance with their respective terms,  except as rights to indemnification
    thereunder  may be limited by applicable  law and except as the  enforcement
    thereof may be limited by bankruptcy, insolvency, reorganization, moratorium
    or other similar laws relating to or affecting  creditors'  rights generally
    or by general equitable principles.

             (ii) The execution and delivery by the Selling  Shareholder of, and
    the  performance by the Selling  Shareholder of its obligations  under,  the
    Underwriting Agreement, the Custody Agreement and the Power of Attorney will
    not  contravene  or conflict  with,  result in a breach of, or  constitute a
    default under, the organizational documents of the Selling Shareholder,  or,
    to the best of such counsel's knowledge, violate or contravene any provision
    of  applicable  law or  regulation,  or  violate,  result  in a breach of or
    constitute a default under the terms of any other agreement or instrument to
    which the  Selling  Shareholder  is a party or by which it is bound,  or any
    judgment,  order or decree  applicable  to the  Selling  Shareholder  of any
    court,  regulatory  body,   administrative  agency,   governmental  body  or
    arbitrator having jurisdiction over the Selling Shareholder.

             (iii) The Selling  Shareholder  has the legal right and power,  and
    all   authorizations   and   approvals   required   by  law  and  under  its
    organizational  documents,  if  applicable,  to enter into the  Underwriting
    Agreement,  the  Custody  Agreement  and the  Power  of  Attorney,  to sell,
    transfer and deliver all of the Secondary  Securities  which may sold by the
    Selling Shareholder under the Underwriting  Agreement and to comply with its
    other  obligations   under  the  Underwriting   Agreement  and  the  Custody
    Agreement, except such as may be required under state securities or blue sky
    laws.

             (iv) Upon payment for the  Secondary  Securities  to be sold by the
    Selling  Shareholder  (such  Secondary  Securities,  the "Subject  Secondary
    Securities") in accordance with the  Underwriting  Agreement and pursuant to
    the Custody Agreement, and an indication from DTC by book entry that, in the
    case of each Underwriter,  the Subject Secondary  Securities being purchased
    by or on  behalf  of such  Underwriter  have been  credited  to  "securities
    accounts" (as defined


                                   Exhibit B-1



    in Section 8-501 of the Uniform Commercial Code as in effect in the State of
    New York (the "NY UCC")) of such  Underwriter  with DTC, under Section 8-501
    of the NY UCC, each Underwriter will acquire a valid "security  entitlement"
    (as  defined  in  Section  8-102  of the NY  UCC) to the  Subject  Secondary
    Securities being so purchased by or on behalf of such  Underwriter,  and, to
    the extent  governed by the UCC, no action based on any "adverse  claim" (as
    defined in Section 8-102 of the NY UCC) to such Subject Secondary Securities
    (or  security  entitlement  with  respect  thereto) may properly be asserted
    against such  Underwriter  with respect to such  security  entitlement.  For
    purposes of the opinion in this paragraph (iv), we have assumed that (a) DTC
    is a "clearing corporation" (as defined in Section 8-102 of the NY UCC), (b)
    neither DTC nor any  Underwriter  has notice of any  adverse  claim (as such
    phrase is defined in Section  8-102 of the NY UCC) to the Subject  Secondary
    Securities,   and  (c)  the  agreement  between  each  Underwriter  and  DTC
    pertaining to the securities accounts of each Underwriter with DTC specifies
    that it is governed by the law of the State of New York.

             (v) To the best of such counsel's knowledge, no consent,  approval,
    authorization  or other order of, or  registration or filing with, any court
    or governmental authority or agency, is required for the consummation by the
    Selling  Shareholder of the  transactions  contemplated in the  Underwriting
    Agreement or the Custody Agreement,  except as required under the Securities
    Act and applicable state securities or blue sky laws.

RE:      Acadia Realty Trust (the "Company")

Ladies & Gentlemen:

         The undersigned is an owner of record or beneficially of certain
Securities of Beneficial Interest of the Company ("Securities") or securities
convertible into or exchangeable or exercisable for Securities. The Company
proposes to carry out a public offering of Securities (the "Offering") for which
_________________ will act as the representative (the "Representative") of the
underwriters, if any. The undersigned recognizes that the Offering will be of
benefit to the undersigned and will benefit the Company and hereby acknowledges
the receipt and sufficiency of other good and valuable consideration for
executing this letter agreement. The undersigned further acknowledges that you
and the other underwriters, if any, are relying on the representations and
agreements of the undersigned contained in this letter in carrying out the
Offering and in entering into an underwriting agreement (the "Underwriting
Agreement") with the Company with respect to the Offering.

         In consideration of the foregoing, the undersigned hereby agrees that
the undersigned will not, (and will cause any spouse or immediate family member
of the spouse or the undersigned living in the undersigned's household not to),
without the prior written consent of the Representative (which consent may be
withheld in its sole discretion), directly or indirectly, sell, offer, contract
or grant any option to sell (including without limitation any short sale),
pledge, transfer, establish an open "put equivalent position" within the meaning
of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, or
otherwise dispose of any shares of Securities, options or warrants to acquire
shares of Securities, or securities exchangeable or exercisable for or
convertible into shares of Securities currently or hereafter owned either of
record or beneficially (as defined in Rule 13d-3 under the Securities Exchange
Act of 1934, as amended) by the undersigned (or such spouse or family member),
or publicly announce an intention to do any of the foregoing, for a period
commencing on the date hereof and continuing through the close of trading on the
date ninety (90) days after the date of the Prospectus (the "Lock-Up Period").
The undersigned also agrees and consents to the entry, by the Company, of stop
transfer instructions, which shall remain in effect only during the Lock-Up
Period, with the Company's transfer agent and registrar against the transfer of
shares of Securities or securities convertible into or exchangeable or
exercisable for Securities held by the undersigned except in compliance with the
foregoing restrictions or with the consent of the Representative; provided,
however, that nothing herein shall prohibit (i) transfers to affiliates, family
members, charitable remainder trusts or


                                  Exhibit C-1



charitable institutions that agree in writing to be bound by the terms of this
letter agreement or (ii) the exercise by the undersigned of outstanding stock
options held by the undersigned, provided the Securities received by the
undersigned upon any such exercise shall be subject to the provisions of this
letter agreement during the Lock-Up Period.

         If for any reason the Underwriting Agreement shall be terminated prior
to the Closing Date (as defined in the Underwriting Agreement), the agreement
set forth above shall likewise be terminated.

         This letter agreement shall become effective upon the execution of the
Underwriting Agreement by all the parties named therein. Once effective, this
agreement is irrevocable and will be binding on the undersigned and the
respective successors, heirs, personal representatives, and assigns of the
undersigned.
