Item 1. Business

Cabot Industrial Properties, L.P.

Cabot Industrial Properties, L.P. ("Cabot L.P.") was organized on October 10,
1997 as a Delaware limited partnership to continue and expand the national
industrial real estate business of Cabot Partners Limited Partnership ("Cabot
Partners"). The sole general partner of Cabot L.P. is Cabot Industrial Trust
(Cabot Trust), a Maryland real estate investment trust. Cabot L.P. and Cabot
Trust are organized in what is commonly referred to as an umbrella partnership,
or "UPREIT" structure, meaning that all of Cabot Trust's properties are held and
its business is conducted primarily through Cabot L.P. At December 31, 1999,
Cabot Trust held a 93% partnership interest in Cabot L.P. The balance of the
partnership interests in Cabot L.P. at that date was primarily held by investors
who had contributed properties or assets to Cabot L.P. in connection with the
commencement of the business of Cabot Trust and Cabot L.P. in their current
form, or in subsequent transactions. See "Formation Transactions; Organizational
Structure".

Cabot Trust is an internally managed, fully integrated real estate company
which, through Cabot L.P., acquires or develops, leases, manages and holds for
investment industrial real estate properties in principal markets throughout the
United States. At December 31, 1999, Cabot L.P. owned a geographically
diversified portfolio of 320 industrial properties having an aggregate of
approximately 38 million rentable square feet, approximately 97% of which space
was leased to 638 tenants. The properties are located in 22 states in each of
the five principal regions (West, Midwest, Northeast, Southeast and Southwest)
of the United States. As of December 31, 1999, no single tenant accounted for
more than 2.6% of Cabot L.P.'s total annualized base rent. Between December 31,
1999 and February 29, 2000, Cabot L.P. acquired 14 industrial properties
containing approximately 1,366,000 square feet and contracted to purchase seven
additional industrial properties containing approximately 770,000 square feet.

Cabot L.P.'s goal is to be the preeminent national real estate company focused
on serving a variety of industrial space users. As of December 31, 1999, Cabot
L.P. has a significant market presence across the United States, with properties
in a total of 22 markets (19 of which Cabot L.P. has identified as principal
targeted markets), including 11 markets in which Cabot L.P. owns properties with
more than one million rentable square feet. Its tenant base ranges from large
national distributors using bulk warehouse and other types of industrial space
in multiple locations to small companies located in single workspace properties.
Cabot L.P. believes that its geographic diversification and substantial presence
in multiple markets is a strategic advantage that allows it to serve industrial
space users with multiple site and industrial property type requirements, to
compete more effectively in its individual markets, and to respond quickly to
acquisition opportunities as they arise.

Cabot L.P. offers a broad spectrum of industrial property types to meet the
diverse needs of its tenants. Its properties are of three general types: bulk
distribution properties, multitenant distribution properties and workspace
properties (light industrial, R&D and similar facilities).

In addition to acquiring existing industrial properties, Cabot L.P. is engaged
in the development and construction of new properties. Its development
activities are conducted through relationships with local builders selected by
Cabot L.P. As of December 31, 1999, Cabot L.P. had approved 17 development
projects with total projected development costs of approximately $172.0 million.
The


                                       1
<PAGE>

projects are located in 12 of Cabot L.P.'s existing submarkets and involve
construction of each of Cabot L.P.'s principal property types. Sixty-five
percent of the square footage in development projects which have reached shell
completion, with estimated total project costs of $66.8 million, have been
leased.

Cabot L.P. is taxed as a partnership under the Internal Revenue Code of 1986
(the "Code"), as amended. As a partnership, Cabot L.P. will not be subject to
federal and state income taxes as the partners report their respective shares of
net taxable income on their individual returns.

Cabot L.P.'s principal executive offices are located at Two Center Plaza, Suite
200, Boston, Massachusetts 02108, and its telephone number is (617) 723-0900.
Cabot L.P. has regional offices in the Atlanta, Baltimore, Chicago, Cincinnati,
Dallas, Los Angeles, Orlando and Phoenix markets.

Formation Transactions; Organizational Structure

In February 1998, Cabot Trust completed an initial public offering of 8,625,000
common shares of beneficial interest ("Common Shares") and a private placement
of 1,000,000 Common Shares, in each case at an offering price of $20.00 per
Common Share (collectively, the "Offerings"). The Offerings resulted in net
proceeds to Cabot Trust of approximately $176.3 million, which were contributed
to Cabot L.P. in exchange for a corresponding number of units of partnership
interest. Concurrently with the completion of the Offerings, Cabot Trust also
completed a series of business combinations (the "Formation Transactions")
involving Cabot Partners and a number of property-owning entities, including
both entities organized by Cabot Partners and its institutional advisory
clients, and institutional investors that had no prior relationship with Cabot
Partners (collectively, the "Contributing Investors"). The Formation
Transactions resulted, among other things, in the transfer of ownership of 122
industrial properties to Cabot L.P.

Cabot Trust's interest in Cabot L.P. entitles it to share in cash distributions
from, and in the profits and losses of, Cabot L.P. in proportion to Cabot
Trust's percentage ownership (apart from tax allocations of profits and losses
to take into account pre-contribution property appreciation). Limited
partnership interests in Cabot L.P. ("Units") are convertible into Common Shares
of Cabot Trust on a one-for-one basis subject to Cabot Trust's right to redeem
such interests for cash in lieu of issuing Common Shares.

As the general partner of Cabot L.P., Cabot Trust has the exclusive power under
the agreement of limited partnership to manage and conduct the business of Cabot
L.P. Cabot Trust holds one Unit in Cabot L.P. for each Common Share that it has
issued. The net proceeds of the issuance of Common Shares of Cabot Trust are
required to be contributed to Cabot L.P. in exchange for a corresponding number
of Units of partnership interest.

Business Strategies

Cabot L.P.'s fundamental business objective is to maximize the total return to
its unitholders through growth in its cash available for distribution per
partnership Unit and in the value of its portfolio of industrial properties and
operations. Cabot L.P. believes that it is well positioned to take advantage of
the opportunities presented by today's changing industrial real estate markets
through the business strategies and operations described below.


                                       2
<PAGE>

Leveraging Substantial National Market Presence

Cabot L.P. believes that maintaining and expanding its market presence in its 19
principal targeted markets across the country is an important factor in
achieving future growth and its targeted returns on investment.

Cabot L.P. believes that its substantial presence in its principal markets
provides significant strategic advantages. Foremost among these advantages is
that, through a national tenant marketing program, Cabot L.P. is well positioned
to market its industrial space to national companies and third-party logistics
companies who have space requirements in multiple markets. The national tenant
marketing program emphasizes the advantages of dealing with a single source for
a company's industrial space needs in addition to the quality and attractive
locations of Cabot L.P.'s properties. These advantages include greater
efficiency of lease negotiations and day-to-day property management, as well as
better understanding of the tenants' current needs and prospective space
requirements. Cabot L.P. serves 55 tenants in multiple properties. These tenants
accounted for approximately 28% of Cabot L.P.'s annualized net rents as of
December 31, 1999.

Cabot L.P. believes that having a substantial inventory of properties and
significant leasing activities within each local market increases its visibility
to prospective tenants and enables it to establish strong relationships with
leasing brokers and other local market participants. These brokers and market
participants serve as sources of information and potential tenant referrals. In
addition, larger inventories increase Cabot L.P.'s opportunities to relocate
tenants to one or more of its other properties as their needs change. Increased
size of operations in a market also enables Cabot L.P. to bear the costs of the
management personnel and facilities needed to build long-term tenant
relationships in that market.

Serving a Variety of Tenants By Offering a Broad Spectrum of Industrial Property
Types

Cabot L.P. believes that its strategy of offering a variety of industrial
property types provides complementary benefits in meeting Cabot L.P.'s growth
objectives. Offering a broad spectrum of industrial property types and Cabot
L.P.'s size and professional management capability enable Cabot L.P. to provide
better service, on a more cost-efficient basis, to national customers who need
various types of workspace properties, in addition to distribution space, for
their local operations. At the same time, offering a variety of industrial
property types suitable for smaller companies enables Cabot L.P. to capture a
larger share of the growth in its chosen industrial property markets. Cabot
L.P.'s strategy of offering diverse industrial property types also enables Cabot
L.P. to pursue opportunities as they arise within its tenant base by responding
to shifts in demand at different stages of the economic cycle.

Growth Strategies

Cabot L.P. intends to achieve its growth objectives through a combination of
property acquisitions, development and internal growth.

Acquisitions

Cabot L.P. seeks to capitalize on its competitive advantages primarily by
acquiring additional modern, high-quality properties in attractive submarkets
within the industrial markets that it currently serves. During 1999, Cabot L.P.
acquired 113 properties, consisting of 10 million rentable square feet in 14
targeted markets, totaling $448.3 million in 42 separate transactions. Through
February 29, 2000, Cabot L.P. acquired 14 additional properties in the Atlanta,
Harrisburg and Phoenix markets, consisting of approximately 1,366,000 rentable
square feet. In addition, Cabot L.P. entered into


                                       3
<PAGE>

contracts to acquire properties consisting of approximately 770,000 rentable
square feet in the Atlanta, Charlotte, Dallas, San Diego and San Francisco
markets. In the near term, Cabot L.P. expects to moderate the pace of its
acquisition program, compared to prior years.

      Investment Criteria

Cabot L.P. follows a disciplined, value-oriented strategy in its property
acquisitions. Cabot L.P. seeks to acquire modern, cost-efficient buildings
located in key national and regional distribution centers. Cabot L.P.'s
investment considerations include (i) capitalization rates, (ii) economic
fundamentals in the market, (iii) replacement costs, (iv) rent levels and
trends, (v) construction quality and property condition, (vi) historical
occupancy rates, (vii) access to transportation, (viii) proximity to housing,
(ix) operating costs, (x) location in modern industrial parks and (xi) local
crime rates.

      Emphasis on Market Research

Cabot L.P.'s property acquisitions are based on extensive research in each
targeted market regarding (i) economic and demographic trends, (ii) the supply
of and demand for industrial space in targeted submarkets, (iii) existing and
potential tenant space requirements, (iv) rent levels and trends and (v) the
physical characteristics of buildings within the market. Cabot L.P.'s research
includes extensive in-market activity by its employees, including physical site
inspections and continuing contacts with leasing brokers and other local market
participants in the local markets.

      Diversification of Industrial Property Types

As of December 31, 1999, 69% of Cabot L.P.'s properties, based on annualized net
rents, have been bulk distribution and multitenant distribution facilities
because of the opportunities for superior returns such properties have provided.
While Cabot L.P. expects that both types of properties will continue to be part
of its future acquisition program, Cabot L.P. believes that workspace properties
(light industrial, R&D and similar facilities) are also attractive in selected
markets where they are in limited supply and strong demand exists. Cabot L.P.
continues to increase its acquisitions of workspace properties, which
represented approximately 31% of its properties at December 31, 1999 based on
annualized net rents. During 1999, Cabot L.P.'s acquisitions as defined by cost
were 22% bulk distribution, 40% multitenant distribution and 38% workspace
properties.

      Relationships with Institutional Real Estate Investors

Prior to the formation of Cabot L.P., management operated Cabot Partners, which
was focused on serving public and private pension funds and other institutional
real estate investors in connection with investments in and management of
industrial real estate. This has provided Cabot L.P.'s management with an
extensive knowledge of and, Cabot L.P. believes, a favorable reputation with
such investors. Cabot L.P. believes that it will benefit from its relationships
with these investors through further acquisitions as they increasingly seek to
securitize their direct real estate investments.

      Capital Resources and UPREIT Structure

As of December 31, 1999, Cabot L.P. had a debt-to-total market capitalization
ratio of approximately 35%. Cabot L.P. has used its relatively unleveraged
capital structure and substantial equity base in its acquisition and development
activities. Cabot L.P. believes that its ability to borrow using its $325
million revolving credit acquisition facility has enhanced its credibility with
potential property sellers. Cabot L.P.'s UPREIT structure, which enables it to
acquire industrial properties on a non-cash basis by exchanging Units in Cabot
L.P. for properties in a tax-deferred manner, also provides an alternative,
depending on market conditions, to a taxable cash sale for tax-paying property
owners.


                                       4
<PAGE>

Development

Cabot L.P.'s senior management has extensive real estate development experience,
including experience derived from the industrial park development activities of
Cabot, Cabot and Forbes, a nationwide real estate development, investment,
construction and management firm that pioneered the development of large-scale,
planned industrial parks. Cabot L.P. believes that in select targeted markets
there are attractive opportunities for new development with potentially greater
returns than those available from the purchase of existing stabilized
properties, and Cabot L.P. pursues a development program where such
opportunities exist. Cabot L.P. is also engaging its existing tenants in
discussions about future space needs and, based on such discussions, believes
that financially attractive build-to-suit opportunities from its tenant base may
be available over time. In order to limit overhead expenses, Cabot L.P. executes
its development activities by engaging local or regional builders with whom it
has established strong relationships. Currently, Cabot L.P. is working with nine
local builders. Cabot L.P. intends to expand its in-house development staff as
Cabot L.P.'s development activities increase.

Internal Growth

Cabot L.P.'s primary internal growth strategy is to increase the cash flow
generated by its properties, and from properties that it proposes to acquire by
renewing or replacing expiring leases with new leases at higher rental rates and
through rent increase provisions in its leases. In addition, Cabot L.P. works
actively to (i) maintain its historically high occupancy levels by retaining
existing tenants, thereby minimizing "down time" and re-leasing costs, (ii)
improve the occupancy levels of newly acquired properties that have lower
occupancy levels than Cabot L.P. targets for its existing properties, (iii)
capitalize on economies of scale arising from the size of its portfolio of
properties and (iv) control costs. Cabot L.P. also seeks internal growth by
converting its properties to more intensive, higher-margin uses, if and to the
extent that suitable opportunities to do so arise. Leases covering approximately
13.7% and 16.4% of the total rentable space of Cabot L.P.'s properties will
expire in 2000 and 2001, respectively.

Leases

Cabot L.P.'s properties typically are leased on a triple net basis, meaning that
the tenants pay their proportionate share of real estate taxes and operating
costs. However, some of the properties are leased at higher gross rents with
Cabot L.P. being responsible for paying a stated amount of real estate taxes and
operating costs and tenants being responsible for any and all increases in such
taxes and costs above that stated amount. Excluding lease renewal options, lease
terms typically range from three to five years or, for leases that are renewed,
a shorter period of generally two to three years. Approximately 48% (based on
annualized net rent) of these leases contain provisions for automatic increases
of a specified amount or percentage at a certain point or points during the term
of the lease.

Policies

The following is a description of policies that have been adopted by the Cabot
Trust Board of Trustees for the conduct of the business of Cabot Trust and Cabot
L.P. These policies may be amended or revised from time to time without Cabot
Trust shareholder approval, except that shareholder approval would be required
for Cabot Trust to change its policy of holding its assets and conducting its
business only through Cabot L.P. and its subsidiaries and other affiliates,
including Cabot Advisors, Inc. ("Cabot


                                       5
<PAGE>

Advisors") and joint ventures in which Cabot L.P. or a subsidiary may be a
partner. In addition, changes in policies with respect to conflicts of interest
must be consistent with legal requirements.

Investment Policies

Cabot Trust conducts all of its investment activities through Cabot L.P. and its
subsidiaries and other affiliates, including Cabot Advisors, and may in the
future conduct activities through joint ventures in which Cabot L.P. or a
subsidiary may be a partner. Cabot L.P.'s investment policy is to purchase
income-producing industrial properties primarily for long-term capital
appreciation and rental growth, and to expand and improve its properties or to
sell them, in whole or in part, when the circumstances warrant.

Cabot L.P.'s property investments may be subject to existing mortgage and other
indebtedness or to indebtedness that may be incurred in connection with
acquiring or refinancing such investments. Debt service with respect to such
indebtedness will have a priority over any distributions with respect to the
Units. Investments are also subject to Cabot L.P.'s policy not to be
treated as an investment company under the Investment Company Act of 1940.

Cabot L.P. currently invests primarily in existing improved properties, but also
invests in development projects. It does not limit its investment or development
activities to any geographic area or product type or to a specified percentage
of assets. While Cabot L.P. intends to maintain diversity in its investments in
terms of property location, size and market, Cabot L.P. does not have any limit
on the amount or percentage of its assets that may be invested in any one
property or any one geographic area. Cabot Trust intends to conduct the
investment and development activities of Cabot L.P. in a manner that is
consistent with the maintenance of Cabot Trust's status as a REIT for federal
income tax purposes.

Cabot L.P.'s current portfolio consists of, and its business objectives
emphasize, equity investments in industrial real estate. Cabot L.P. may also
make or invest in loans secured by mortgages or deeds of trust that are
consistent with Cabot Trust's continued qualification as a REIT for federal
income tax purposes, although it has no current plans to do so. These may
include participating or convertible mortgage loans if Cabot L.P. concludes
that it may benefit from the cash flow or any appreciation in value of the
property secured by such mortgages. Investments in real estate mortgage loans
entail the risk that one or more borrowers may default under such loans and that
the collateral securing such loans may not be sufficient to enable Cabot L.P.
to recoup its full investment.

Subject to the limitations on ownership of certain types of assets and the gross
income tests imposed by the Code, Cabot L.P. also may invest in the securities
of other REITs, other entities engaged in real estate activities or other
issuers, including investments made for the purpose of exercising control over
such entities. Cabot L.P. may enter into joint ventures or partnerships for the
purpose of obtaining an equity interest in a particular property in accordance
with its investment policies. Such investments may permit Cabot L.P. to own
interests in larger assets without unduly restricting diversification and,
therefore, add flexibility in structuring its portfolio. Cabot Trust does not
intend to enter into joint ventures or partnerships to make investments that
would not meet its own investment policies.

Financing Policies

As a general policy, Cabot Trust intends to limit its total consolidated
indebtedness incurred by directing the activities of Cabot L.P. so that at the
time any debt is incurred, Cabot L.P.'s debt-to-total market capitalization
ratio does not exceed 40%. Cabot Trust's Declaration of Trust and Bylaws and
Cabot L.P.'s Partnership Agreement do not, however, limit the amount or
percentage of indebtedness that it may incur. Moreover, due to fluctuations in
the value of Cabot L.P.'s portfolio of properties over time, and since any
determination


                                       6
<PAGE>

of its debt-to-total market capitalization ratio is made only at the time debt
is incurred, the debt-to-total market capitalization ratio could exceed the 40%
level. In addition, Cabot L.P. may modify its debt policy from time to time in
light of changes in economic conditions, relative costs of debt and equity
capital, the market values of its properties, general conditions in the market
for debt and equity securities, fluctuations in the market price of its Units,
growth and acquisition opportunities and other factors. If its debt policy were
changed, Cabot L.P. could become more highly leveraged, resulting in an
increased risk of default on its obligations and a related increase in debt
service requirements that could adversely affect the financial condition and
results of operations of Cabot L.P. and its ability to make distributions to
unitholders.

Cabot L.P. has not established any limit on the number or amount of mortgages
that it may place on any single property or on its portfolio as a whole.

The Board of Trustees of Cabot Trust may decide to obtain additional capital,
from time to time through offerings of Cabot Trust's Common or Preferred Shares
or of Cabot L.P.'s partnership units, including preferred units, debt financings
or retention of cash available for distribution (subject to provisions in the
Code concerning the taxability of undistributed REIT income), or a combination
of these methods. As long as Cabot L.P. is in existence, the net proceeds of the
sale of Common Shares or Preferred Shares by Cabot Trust will be transferred to
Cabot L.P. in exchange for that number of Units or Preferred Units that equals
the number of Common Shares or Preferred Shares sold by Cabot Trust.

Cabot Trust presently anticipates that any borrowings would be made through
Cabot L.P., although Cabot Trust may incur indebtedness directly and loan the
proceeds to Cabot L.P. Borrowings may be unsecured or may be secured by any or
all of the assets of Cabot L.P. (to the extent not prohibited by existing debt
arrangements), or any existing or new property-owning partnership and may have
full or limited recourse to all or any portion of the assets of Cabot L.P., or
any existing or new property-owning partnership. Indebtedness incurred may be in
the form of bank borrowings, purchase money obligations to sellers of
properties, publicly or privately placed debt instruments or financing from
institutional investors or other lenders. The proceeds from borrowings may be
used for working capital, to refinance existing indebtedness or to finance
acquisitions, expansions or the development of new properties, and for the
payment of distributions.

Neither Cabot Trust nor Cabot L.P. has any present policy or intention to
repurchase or otherwise acquire any shares, units or other securities issued by
either of them.

Conflict of Interest Policies

Cabot L.P. has adopted policies that are intended to minimize potential
conflicts of interest. However, there can be no assurance that these policies
will be successful in eliminating the influence of such conflicts and, if they
are not successful, decisions could be made that do not fully reflect the
interests of all unitholders.

Policies with Respect to Other Activities

Cabot L.P. may, but does not presently intend to, make investments that are
different from those described herein. Cabot Trust has authority to offer its
Common Shares, other shares of beneficial interest or other securities for cash
or in exchange for property and to repurchase or otherwise reacquire its shares
or any other securities and may engage in such activities in the future. Cabot
L.P. and Cabot Trust have no outstanding loans to other entities or persons,
including officers and Trustees of Cabot Trust, except Cabot Advisors. Cabot
L.P. has not engaged in trading, underwriting or agency distribution or sales of


                                       7
<PAGE>

securities of other issuers and does not currently intend to do so. Cabot L.P.
and Cabot Trust make and intend to continue to make investments in such a way
that neither of them will be treated as an investment company under the
Investment Company Act of 1940. Their policies with respect to such activities
may be reviewed and modified or amended from time to time by the Board of
Trustees of Cabot Trust without approval of Cabot Trust's shareholders or Cabot
L.P.'s limited partners.

Cabot L.P. intends to make investments in a manner consistent with the
requirements of the Code for Cabot Trust to qualify as a REIT unless, because of
changing circumstances or changes in the Code or applicable Treasury
regulations, the Board of Trustees of Cabot Trust determines that it is no
longer in the best interests of Cabot Trust to qualify as a REIT.

Working Capital Reserves

Cabot L.P. intends to maintain working capital reserves in amounts that the
Board of Trustees of Cabot Trust determines to be adequate to meet normal
contingencies in connection with the operation of Cabot L.P.'s business and
investments.

Declaration of Trust and Bylaw Provisions

Cabot Trust's Declaration of Trust requires, with limited exceptions, that a
majority of Cabot Trust's Board of Trustees be comprised of individuals who are
not officers or employees of Cabot Trust ("Independent Trustees"). This
requirement may not be amended, altered, changed or repealed without the
affirmative vote of a majority of all of the outstanding shares of Cabot Trust
entitled to vote on the matter. The Declaration of Trust also includes a
provision generally permitting Cabot Trust to enter into any agreement or
transaction with any person, including any Trustee, officer, employee or agent
of Cabot Trust.

Cabot Trust's Bylaws provide that Section 2-419 of the Maryland General
Corporation Law, relating to transactions by interested directors, will be
available for and apply to contracts and other transactions between Cabot Trust
and any of its Trustees or between Cabot Trust and any other trust, corporation
or other entity of or in which any of Cabot Trust's Trustees is a trustee or
director or has a material financial interest. Under Section 2-419, a contract
or other transaction between a corporation and any of its directors and any
other corporation, firm or other entity in which any of its directors is a
director or has a material financial interest is not void or voidable solely
because of (a) the common directorship or interest, (b) the presence of the
director at the meeting of the board or a committee of the board that
authorizes, approves or ratifies the contract or transaction, (c) the counting
of the vote of the director for the authorization, approval or ratification of
the contract or transaction if either (i) after disclosure of the interest, the
transaction is authorized, approved or ratified by the affirmative vote of a
majority of the disinterested directors, or by the affirmative vote of a
majority of the votes cast by shareholders entitled to vote other than the votes
of shares owned of record or beneficially by the interested director or such
corporation, firm or other entity, or (ii) the transaction is fair and
reasonable to the corporation.

Cabot L.P. Partnership Agreement

The Cabot L. P. Partnership Agreement gives Cabot Trust, in its capacity as
general partner, full and exclusive discretion in managing and controlling the
business of Cabot L.P. and in making all


                                       8
<PAGE>

decisions affecting the business and assets of Cabot L.P., with limited
exceptions. In the Partnership Agreement, the limited partners have acknowledged
and agreed that Cabot Trust is acting on behalf of both Cabot L.P. and Cabot
Trust's shareholders generally and that, in its capacity as general partner of
Cabot L.P., Cabot Trust is under no obligation to consider separate interests of
the Cabot L.P. limited partners in deciding whether to cause Cabot L.P. to take
or to decline to take, any actions which Cabot Trust, in its capacity as general
partner, has undertaken in good faith on behalf of Cabot L.P. In addition, Cabot
Trust in its capacity as general partner is not responsible for any misconduct
or negligence on the part of its agents, provided that such agents were
appointed in good faith. The Cabot L.P. Partnership Agreement also provides that
neither Cabot Trust nor any of its affiliates (including its officers and
Trustees) may sell, transfer or convey any property to, or purchase any property
from, Cabot L.P., except on terms that are fair and reasonable and no less
favorable than would be obtained from an unaffiliated party.

Security Holder Reports

Cabot Trust makes annual reports to its shareholders regarding the business of
Cabot Trust and Cabot L.P. that include audited consolidated financial
statements. Cabot L.P. does not currently provide separate annual or other
reports to security holders of Cabot L.P. and does not expect to do so, except
to the extent it may specifically undertake to do so in connection with future
issuances of debt or other securities.

Competition

Numerous industrial properties compete with Cabot L.P.'s properties in
attracting tenants to lease space and additional properties can be expected to
be built in the markets in which the properties are located. The number and
quality of competitive industrial properties in a particular area has a material
effect on Cabot L.P.'s ability to lease space at the properties or at newly
acquired properties and on the rents charged. Some of these competing properties
may be newer or better located than Cabot L.P.'s properties.

In addition, the industrial real estate acquisition market has become highly
competitive. There are a significant number of buyers of industrial property,
including other publicly traded industrial REITs, many of which have significant
financial resources. Accordingly, it is possible that Cabot L.P. may not be able
to meet its targeted level of property acquisitions and developments due to such
competition or other factors that may have an adverse effect on Cabot L.P.'s
expected growth in Funds from Operations ("FFO").

Insurance

Cabot L.P. carries commercial general liability insurance, standard "all-risk"
property insurance, flood, earthquake and rental loss insurance with respect to
its properties with policy terms and conditions customarily carried for similar
properties. However, the insurance is subject to normal limitations on the
amounts of coverage and certain types of losses (such as from wars or from
earthquakes for properties located in California) may be either uninsurable or
not economically insurable. Should an uninsured loss or a loss in excess of the
amount of the insurance coverage occur, Cabot L.P. could lose the capital
invested in a property, as well as the anticipated future revenue from that
property, and


                                       9
<PAGE>

Cabot L.P. would continue to be obligated on any mortgage indebtedness or other
obligations related to the property.

In light of the California earthquake risk, California building codes have since
the early 1970's established minimum construction standards for all new
buildings and also contain guidelines for seismic upgrading of existing
buildings that are intended to reduce the possibility and severity of loss from
earthquakes. The construction standards and upgrading, however, do not eliminate
the possibility of earthquake loss. Cabot L.P.'s current policy is to obtain
earthquake insurance if available at acceptable cost. As of December 31, 1999,
all of its 74 properties located in California are covered by earthquake
insurance in amounts believed by management to be reasonable. At December 31,
1999, seismic upgrading had been completed on 19 of the California properties
and seismic upgrading is expected to be completed on nine additional California
properties by December 31, 2000. Cabot L.P. currently maintains blanket
earthquake insurance coverage for all properties located outside California in
amounts Cabot L.P. believes to be reasonable.

Environmental Matters

Under various federal, state and local environmental laws, ordinances and
regulations, a current or previous owner or operator of real property may be
liable for the costs of removal or remediation of hazardous or toxic substances
on, under or in such property. Such laws often impose liability whether or not
the owner or operator knew of, or was responsible for, the presence of such
hazardous or toxic substances.

In addition, the presence of hazardous or toxic substances, or the failure to
remediate such property properly, may adversely affect the owner's ability to
borrow using such real property as collateral. Persons who arrange for the
disposal or treatment of hazardous or toxic substances may also be liable for
the costs of removal or remediation of hazardous substances at the disposal or
treatment facility, whether or not such facility is or ever was owned or
operated by such person.

Certain environmental laws and common law principles could be used to impose
liability for release of and exposure to hazardous substances and third parties
may seek recovery from owners or operators of real properties for personal
injury or property damage associated with exposure to released hazardous
substances. As the owner of real properties, Cabot L.P. may be potentially
liable for any such costs.

Phase I environmental site assessment reports ("Phase I ESAs") were obtained by
our original Contributing Investors in connection with their initial
acquisitions of the properties, or were obtained by Cabot Trust in connection
with the transactions resulting in Cabot Trust's formation as a publicly traded
company. In accordance with Cabot Trust's acquisition policies, Cabot Trust has
also obtained Phase I ESAs for all of the properties acquired since the
completion of the Formation Transactions. The purpose of Phase I ESAs is to
identify potential sources of contamination for which Cabot L.P. may be
responsible and to assess the status of environmental regulatory compliance. The
earliest of the Phase I ESAs for Cabot L.P.'s properties were obtained in 1988
and Phase I ESAs on approximately 14% of the properties owned as of December 31,
1999 were obtained prior to 1995. Commonly accepted standards and practices for
Phase I ESAs have evolved to encompass higher standards and more extensive
procedures over the period of 1988 to the present.

The Phase I ESAs obtained for Cabot L.P.'s properties have not revealed any
environmental liability that Cabot L.P. believes would have a material adverse
effect on its business, assets or results of


                                       10
<PAGE>

operations, nor is Cabot L.P. aware of any such material environmental
liability. It is possible, even if prepared in accordance with professional
standards, that Phase I ESAs relating to the subject properties do not reveal
all environmental liabilities. Moreover, future laws, ordinances or regulations
may impose material environmental liability or the properties' current
environmental condition may be affected by tenants, by the condition of land or
operations in the vicinity of the properties (such as the presence of
underground storage tanks) or by third parties unrelated to Cabot L.P.

Cabot Advisors

Cabot Advisors provides investment advisory and asset management services to the
former clients of Cabot Partners that elected not to contribute some or all of
their industrial properties to Cabot Trust. In addition, Cabot Advisors provides
property management services to Cabot L.P. and to the properties of some clients
that are not associated with Cabot Trust. Cabot L.P. intends to explore
opportunities for co-investment, however, Cabot Advisors will not provide
services relating to any industrial real estate acquisition or development
activities that would conflict with Cabot L.P.'s own acquisition and development
activities. Cabot L.P. believes that its investment in Cabot Advisors will help
it achieve economies of scale with its property management systems, increase
market penetration and provide access to further acquisition opportunities.

To permit Cabot Trust to share in the income of Cabot Advisors while maintaining
its status as a REIT under the law as currently in effect, Cabot L.P. owns all
of Cabot Advisors' non-voting preferred stock (representing 95% of its economic
interest in Cabot Advisors) and Ferdinand Colloredo-Mansfeld, Cabot Trust's
Chief Executive Officer, owns all of Cabot Advisors' voting common stock
(representing 5% of its economic interest therein). Although Cabot Trust
receives substantially all of the economic benefit of Cabot Advisors' business
through distributions from Cabot L.P., Cabot Trust is not able to vote on the
election of Cabot Advisors' directors or officers and, as a result, does not
have the ability to control Cabot Advisors' operations or require its board of
directors to declare and pay cash dividends.

In late 1999, the REIT Modernization Act (RMA) was signed into law, to take
effect on January 1, 2001. The RMA will permit Cabot Trust and any corporation
in which it invests to elect to treat such corporation as a taxable REIT
subsidiary, which will be subject to corporate taxation on its earnings, but
which will be permitted to engage in certain activities that REITs and their
controlled subsidiaries cannot currently perform without jeopardizing REIT
status. Cabot Trust is currently assessing the impact of the RMA on its
operations and the operations of Cabot Advisors.

Employees

At December 31, 1999, Cabot L.P. and Cabot Advisors employed 95 persons, none of
who are represented by any collective bargaining organization. Cabot L.P.
believes it has good relations with its employees.

Item 2. Properties

For descriptive purposes, Cabot L.P.'s properties may generally be grouped into
three property types: bulk distribution properties, multitenant distribution
properties and workspace properties.


                                       11
<PAGE>

Bulk distribution properties are oriented primarily to large national and
regional distribution tenants. These properties generally have at least 100,000
square feet of rentable space, building depths of at least 240 feet, clear
heights of 24 feet or more, truck courts in excess of 100 feet in depth to
accommodate larger modern trucks, a ratio of loading docks to rentable space of
one or more per 10,000 square feet and a location with good access to interstate
highways.

Multitenant distribution properties are oriented primarily to smaller regional
and local distribution tenants, and are generally designed to be subdivided to
suit tenants whose space requirements generally range from 10,000 square feet to
100,000 square feet. These properties generally have clear heights of 20 feet or
more, building depths of less than 240 feet (unless configured with loading
docks on two sides) and a location with good access to regional and interstate
highways. Both types of distribution property are used predominantly for the
storage and distribution of goods.

Workspace properties are designed to serve a variety of industrial tenants with
workspace-related requirements, including light manufacturing and assembly,
research, testing, re-packaging and sorting, back office and sales office
functions. Workspace tenants include smaller companies whose space requirements
generally range from 3,000 square feet to 70,000 square feet. Workspace
properties generally have clear heights of 14 to 24 feet, attractive building
exteriors, office finish of up to 30% or more, parking ratios of one to four
spaces per 1,000 rentable square feet and locations with good access to
executive residential areas and local highways, labor supply and dining and
shopping amenities.

The table set forth below summarizes information regarding Cabot L.P.'s
properties and markets as of December 31, 1999. All of the properties listed are
owned, directly or through title holding entities, by Cabot L.P.

      (1)   Cabot L.P. paid a distribution with respect to these quarters in the
            quarter immediately following the quarter in which the cash flow was
            generated and the distribution was deemed.

The operating cash flow realized by Cabot L.P. and the amount available for
distributions to unitholders is affected by a number of factors, including the
property revenues of Cabot L.P., the operating expenses of Cabot L.P., the
distributions to Preferred Unitholders of Cabot L.P., the interest expense on
borrowings and capital expenditures. Future distributions by Cabot L.P. and
Cabot Trust will be at the discretion of the Board of Trustees of Cabot Trust
and will depend on the actual FFO of Cabot L.P., its financial condition and
capital requirements, the annual income distribution requirements under the REIT
provisions of the Code and such other factors as Cabot Trust's Board of Trustees
deem relevant.

INTRODUCTION

Cabot L.P.

Cabot L.P. owns and operates a diversified portfolio of bulk distribution,
multitenant distribution and "workspace" (light industrial, R&D and similar
facilities) properties throughout the United States. Cabot L.P. was formed on
October 10, 1997, but did not begin operations as a fully integrated real estate
company until the completion of the Formation Transactions and Offerings on
February 4, 1998, the closing date of Cabot Trust's initial public offering.
Cabot L.P. had no operations prior to February 4, 1998. At December 31, 1999,
Cabot L.P. owned 320 industrial properties, 119 of which properties were
acquired in connection with the Formation Transactions described in Notes 1 and
3 to the consolidated financial statements herein, 84 of which properties were
acquired during 1998 and 113 of which properties were acquired during the year
ended December 31, 1999. In addition, four properties from the development
program were placed into service in 1999 and 1998. In the near term, Cabot L.P.
expects to moderate the pace of its acquisition program, compared to prior
years, and Cabot L.P. expects development projects will provide an increasing
component of growth due to the higher potential returns on capital.

Cabot Partners

Cabot Partners was the real estate advisory and management entity that was the
sponsor and organizer of Cabot Trust. Its revenues consisted primarily of asset
management and acquisition fees earned under advisory contracts with large
institutional investors.

RESULTS OF OPERATIONS

Cabot L.P.

Since Cabot L.P. was formed in October 1997 and did not begin operations until
February 4, 1998, the results for the year ended December 31, 1998 represent
activity for 331 days (approximately 11 months) only, and no comparison of
results to prior periods is available.


                                       26
<PAGE>

Year Ended December 31, 1999 Compared with Year Ended December 31, 1998

Net income allocable to partnership unitholders for the year ended December 31,
1999, totaled $57.7 million or $1.32 per unit, compared to $51.0 million or
$1.17 per unit for the year ended December 31, 1998. The increase is the result
of having a full year of operations in 1999 compared to 331 days in 1998 and
increased earnings from additional investments in real estate.

Rental revenues were $157.5 million, including tenant reimbursements of $21.6
million, for the year ended December 31, 1999, compared to $102.4 million,
including tenant reimbursements of $13.4 million, for the year ended December
31, 1998. Total rental revenue of $82.7 million and $72.9 million was generated
in 1999 and 1998, respectively, by the 119 properties owned as of February 4,
1998 as a result of the Formation Transactions and still owned at December 31,
1999 (the "Baseline Properties") and total rental revenue of $73.9 million and
$27.2 million in 1999 and 1998, respectively, was generated by the 201
properties acquired or developed after February 4, 1998. The remainder of total
rental revenue relates to properties sold.

Cabot L.P.'s operating margin (the ratio of total rental revenues minus property
operating and property tax expenses to total rental revenues) decreased slightly
to approximately 81% for the year ended December 31, 1999 compared with 82% for
the year ended December 31, 1998. The decrease is primarily due to a change in
the composition of leases, primarily as a result of acquisition of multitenant
and workspace properties, to more leases where Cabot L.P. pays property and
operating expenses and is reimbursed by the tenants compared to leases where the
tenant pays these expenses directly.

Depreciation and amortization related to real estate investments totaled $31.1
million and $20.9 million for the years ended December 31, 1999 and 1998,
respectively. The increase reflects the acquisition of approximately $448
million of real estate assets in 1999, as well as a full year of expense related
to 1998 acquisitions, and 365 days of operations in 1999 compared to 331 days in
1998.

General and administrative expense increased by $2.1 million, to $8.9 million
for the year ended December 31, 1999. The increase is primarily due to a full
year of operations in 1999 and it also reflects an increase in personnel to
manage the acquisition, development, asset management and financing activity,
from the increase in the number of Cabot L.P.'s properties during the two-year
period. As a percentage of rental revenues, general and administrative expense
decreased to 5.7% in 1999 from 6.7% in 1998.

Interest expense of $25.4 million for the year ended December 31, 1999
represents interest incurred on an additional $115.7 million of secured debt
incurred during 1999, $200.0 million of unsecured debt issued in May 1999, and
additional borrowings under Cabot L.P.'s Acquisition Facility, net of $3.2
million of interest capitalized to development projects. Interest expense of
$7.0 million for 1998, net of $959,000 of interest capitalized to development
projects, was incurred for only 331 days on average indebtedness of $116.2
million for 1998.

During 1998 Cabot L.P. entered into an interest rate hedge transaction (referred
to as the "Treasury Lock") involving the future sale of $100 million of Treasury
securities based on an interest rate of approximately 5.54% for such securities
in anticipation of a future debt issuance of at least $100 million with a
maturity of 10 years. At the March 31, 1999 contractual settlement date for this
transaction, Cabot L.P. paid $2.5 million to its counter party in the
transaction, reflecting the decrease in Treasury security yields since the July
1998 commencement of the transaction. Because an offering of the size and
maturity contemplated when the interest rate hedge transaction was executed was
not


                                       27
<PAGE>

completed by the time of, or shortly after, the March 31, 1999 settlement date
of the transaction, Cabot L.P. recorded a loss related to the settlement of the
treasury lock of approximately $2.5 million during the year ended December 31,
1999.

During 1999, Cabot L.P. sold two properties, which resulted in a net gain of
$2.8 million. On June 22, 1999, Cabot L.P. sold a 120,000 square foot property
located in Massachusetts for a gross sales price of $10.5 million, which
resulted in a gain of $3.4 million, and on August 3, 1999, Cabot L.P. sold a
225,000 square foot property located in New Jersey for a gross sales price of
$6.6 million, which resulted in a loss of $653,000.

Interest and other income, which consists primarily of interest earned on Cabot
L.P.'s invested cash balances and earnings of Cabot Advisors, decreased by
$124,000, from $1.1 million for the year ended December 31, 1998 to $1.0 million
for the year ended December 31, 1999. The decrease is primarily due to a
decrease in Cabot L.P.'s share of earnings of Cabot Advisors for the year ended
December 31, 1999 compared with 1998.

Dividends accruable to Preferred Unitholders, which totaled $6.0 million in
1999, are deducted from Net Income to arrive at Net Income Allocable to
Partnership Units.

Cabot Partners

Year Ended December 31, 1997 Compared with Year Ended December 31, 1996

Revenues, primarily consisting of asset management fees and acquisition fees,
increased by $1.2 million for the year ended December 31, 1997, or 14.8%, to
$9.1 million as compared to $7.9 million for the year ended December 31, 1996.
The increase was due to a $191 million increase in average assets under
management for the year ended December 31, 1997, as compared to the year ended
December 31, 1996, which resulted in an $850,000 increase in asset management
fees. In addition, acquisition fees increased by $262,000 in 1997 as compared to
1996, due to an increase in fee-earning acquisitions of $37 million.

General and administrative expenses increased by $1.2 million for the year ended
December 31, 1997, or 19.7%, to $7.0 million as compared to $5.9 million for the
year ended December 31, 1996. Compensation expense increases accounted for
$798,000, or 69.0%, of the increase. The remainder of the increase was primarily
due to higher professional services fees. General and administrative expenses as
a percentage of revenues for 1997 and 1996 was 77.6% and 74.5%, respectively.

Depreciation and amortization expense increased by $558,000 for the year ended
December 31, 1997, to $977,000, due to increased amortization of two advisory
contracts terminated during 1997.

CAPITAL RESOURCES AND LIQUIDITY

Cabot L.P. intends to rely on cash provided by operations, unsecured and secured
borrowings from institutional sources, and public debt as its primary sources of
funding for acquisition, development, expansion and renovation of properties.
Cabot L.P. may also consider preferred and common equity financing when such
financing is available on attractive terms.

As a result of the completion of the Offerings in February 1998, Cabot Trust
issued 8,625,000 Common Shares to the public and 1,000,000 Common Shares in a
private placement. All of the Common Shares were sold at a price of $20.00 per
share. The proceeds from the Offerings, net of


                                       28
<PAGE>

offering costs, were $176.3 million and were contributed to Cabot L.P. in
exchange for an equal number of Partnership Units.

As discussed in Note 1 to the financial statements, Cabot L.P. issued an
aggregate of $195 million of Cumulative Redeemable Perpetual Preferred Units in
five separate transactions in 1999. The net proceeds from these transactions
were $189.8 million which was used to pay down outstanding balances under the
Acquisition Facility. These Cumulative Redeemable Perpetual Preferred Units are
callable by Cabot L.P. at par on or after the fifth anniversary of issuance.

In March 1998, Cabot L.P. established a $325 million unsecured revolving line of
credit (the "Acquisition Facility"), with Morgan Guaranty Trust Company of New
York as lead agent for a syndicate of banks. The Acquisition Facility is used to
fund property acquisitions, development activities, building expansions, tenant
leasing costs and other general corporate purposes. The Acquisition Facility
contains certain restrictions and requirements such as total debt-to-assets,
debt service coverage and unencumbered assets to unsecured debt ratios, and
other limitations. Cabot L.P. believes cash flow from operations not distributed
to unitholders will be sufficient to cover tenant improvements and other costs
associated with renewal or replacement of current tenants as their leases expire
and recurring non-incremental revenue-generating capital expenditures.

As of December 31, 1999, Cabot L.P. had $163.9 million of fixed rate debt
secured by properties, $163.0 million of unsecured borrowings under its
Acquisition Facility, $200.0 million of unsecured debt and a 35% debt-to-total
market capitalization ratio. The debt-to-total market capitalization ratio is
calculated based on Cabot L.P.'s total consolidated debt as a percentage of the
sum of the market value of its outstanding Partnership Units, plus the
liquidation value of Cumulative Redeemable Perpetual Preferred Units plus debt.

In the normal course of its 2000 operations, through February 29, 2000, Cabot
L.P. purchased approximately $58 million of real estate assets in the current
year and has committed to purchase $41 million of additional real estate assets.
The completed real estate asset acquisitions were primarily funded through
Acquisition Facility borrowings and $6.1 million of assumed debt.

Cabot L.P. entered into an interest rate cap arrangement relating to its
LIBOR-based Acquisition Facility for a notional amount of $100 million for the
period October 1, 1999 through April 1, 2000. This arrangement is intended to
limit the LIBOR component of Cabot L.P.'s interest rate on an equivalent amount
of borrowings to 6.5% per annum.

Cash and cash equivalents totaled $22.0 million at December 31, 1999,
representing an increase of $19.7 million. This was the result of $101.3 million
of cash generated from operating activities and $372.6 million provided by
financing activities, reduced by $454.2 million used in investing activities.

YEAR 2000

During 1999, Cabot L.P. completed its program of determining whether its
business operations would be affected by date sensitive calculation errors that
might result from computers whose programs do not properly recognize the year
2000 (commonly referred to as the "Year 2000 Issue"). Cabot L.P. has not to date
experienced any effects on its results of operations or financial position from
the Year 2000


                                       29
<PAGE>

Issue, nor have any of Cabot L.P.'s vendors communicated to Cabot L.P. that they
have experienced any such effects.

INFLATION

Substantially all of the leases of Cabot L.P.'s properties require the tenant to
pay, as additional rent, either all real estate taxes and operating expenses or
all increases in real estate taxes and operating expenses over a base amount. In
addition, many of such leases provide for fixed or indexed increases (based on
the consumer price index or other measures) in base rent. Management believes
that inflationary increases in operating expenses will be offset, in part, by
these expense reimbursements and contractual rent increases.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

In addition to using equity capital and retained earnings, Cabot L.P. finances
its acquisition and development programs and its ongoing operating cash needs
through the use of debt financing. Cabot L.P. uses short-term revolving debt,
primarily in the form of its Acquisition Facility, and long-term secured and
unsecured debt with original maturities of five years or more. Cabot L.P.
attempts to manage its debt maturities to reduce its exposure to the refinancing
risk that would arise from having significant maturities of principal at a time
when debt capital may not be available or may be available only at unfavorable
interest rates.

Cabot L.P. is exposed to market risk in the form of the effects of changes in
market interest rates on its existing and proposed debt financing. Its
Acquisition Facility bears interest at a variable rate, LIBOR plus 1%, while the
interest rates on proposed fixed-rate unsecured and secured debt instruments
will usually be based on Treasury securities yields plus a market-based spread.
Cabot L.P. has entered into various forms of interest rate protection agreements
with investment-grade financial institutions from time to time for the purpose
of managing a portion of its interest rate risk. For variable rate LIBOR-based
borrowings, these agreements include interest rate collar and interest rate cap
agreements that are intended to limit Cabot L.P.'s effective cost on variable
rate borrowings, either within an agreed range or below an agreed maximum level.
For proposed long-term instruments, Cabot L.P. has also entered into "Treasury
Lock transactions" that are intended to set the Treasury securities component of
the interest cost in advance through agreements for the sale of Treasury
securities having notional amounts and maturities comparable to Cabot L.P.'s
intended debt issuance. Cabot L.P. does not enter into interest rate protection
agreements or any other form of derivative financial instruments for speculative
trading purposes.

As of December 31, 1999, Cabot L.P. was a party to an interest rate cap
agreement that was intended to limit its exposure to changes in LIBOR through
April 1, 2000 on $100 million of borrowings on its Acquisition Facility. Under
the agreement, Cabot L.P.'s counter party is required to pay an amount equal to
interest on that notional principal amount of borrowings to the extent that the
relevant LIBOR exceeds 6.5%.

As of December 31, 1998, Cabot L.P. also had a Treasury Lock agreement in place
for the purpose of setting the Treasury securities component of the interest
rate on an intended future issuance of fixed rate debt. This agreement provided
for the sale of $100 million of 10-year Treasury securities at a yield of 5.54%
on March 31, 1999. Cabot L.P. paid its counter party $2.5 million upon the
maturity of


                                       30
<PAGE>

this agreement, reflecting the decrease in Treasury yields and consequent
increase in cost of the notional amount of Treasury securities to be sold since
the July 1998 commencement date of the transaction.

Taking into account $163.0 million of variable rate borrowings that Cabot L.P.
had outstanding under its Acquisition Facility at December 31, 1999, and the
above-described interest rate cap agreement that was in effect at that date, an
instantaneous increase of 100 basis points in LIBOR at that date would, if LIBOR
remained at the increased levels thereafter, result in an estimated $1.4 million
reduction in Cabot L.P.'s net income in 2000. This estimate is provided for the
purpose of illustrating the possible effects on Cabot L.P.'s results of
operations of changing interest rates and Cabot L.P.'s interest rate protection
agreements. It does not take into account any other effects that changes in
interest rates might have on Cabot L.P.'s operations, such as higher interest
rates on new fixed rate borrowings, nor does it consider any additional interest
rate protection agreements that Cabot L.P. might enter into in reaction to or in
anticipation of changes in interest rates. While an increase in LIBOR of 100
basis points over a relatively short time period is possible, it is unlikely
that interest rates would increase instantaneously or stay at the same rate for
a sustained period as assumed for purposes of the illustration.

As of December 31, 1999, Cabot L.P. also had $163.9 million of fixed rate debt
at stated rates ranging from 7.25% to 9.67% secured by certain properties and
$200.0 million of fixed rate unsecured debt at a stated rate of 7.125%. The
current and future use of fixed rate debt is advantageous to Cabot L.P., as
compared with variable rate debt, in times of rising interest rates. However, in
an environment of falling interest rates, fixed rate debt would place Cabot L.P.
at a disadvantage as compared with competitors having larger components of
variable rate debt.

                    Report of Independent Public Accountants

To the Partners of Cabot Industrial Properties, L.P.:

We have audited the accompanying consolidated balance sheets of Cabot Industrial
Properties, L.P. and subsidiaries (Cabot L.P.), a Delaware Partnership, as of
December 31, 1999 and 1998, and the related consolidated statements of
operations, partners' equity and cash flows for the years then ended (Note 1).
These financial statements are the responsibility of Cabot L.P.'s management.
Our responsibility is to express an opinion on these consolidated financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Cabot Industrial
Properties, L.P. and subsidiaries as of December 31, 1999 and 1998 and the
results of their operations and their cash flows for the years then ended, in
conformity with generally accepted accounting principles.

Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index to the
financial statements is presented for purposes of complying with the Securities
and Exchange Commission's rules and is not a required part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audits of the basic financial statements and, in our
opinion, fairly states, in all material respects, the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

                                December 31, 1999

1. GENERAL

Organization

Cabot Industrial Properties, L.P. (Cabot L.P.), a Delaware limited
partnership, was formed on October 10, 1997. The general partner of Cabot L.P.
is Cabot Industrial Trust (Cabot Trust), a Maryland real estate investment
trust which was also formed on October 10, 1997. As the general partner of Cabot
L.P., Cabot Trust has the exclusive power under the agreement of limited
partnership to manage and conduct the business of Cabot L.P. Cabot Trust is a
fully-integrated, internally-managed real estate company formed to continue and
expand the national real estate business of Cabot Partners Limited Partnership
(Cabot Partners). Cabot Trust qualifies as a real estate investment
trust (a REIT) for federal income tax purposes. Since Cabot L.P. was formed on
October 10, 1997, and did not begin operations until February 4, 1998 (see The
Formation Transactions below), the results for the year ended December 31, 1998,
represent activity for 331 days, or approximately 11 months.

The Formation Transactions

On February 4, 1998, under a Contribution Agreement executed by Cabot Trust,
Cabot L.P., Cabot Partners, and various other contributors, 122 industrial real
estate properties, certain real estate advisory contracts and other assets were
(i) contributed to Cabot L.P. in exchange for general partnership units in Cabot
L.P. (Units) that may, subject to certain restrictions, be exchanged for Common
Shares of Cabot Trust (Common Shares) or (ii) contributed to Cabot Trust in
exchange for Common Shares. The properties contributed to Cabot Trust were
concurrently contributed by it to Cabot L.P. in exchange for the number of Units
equal to the number of Common Shares exchanged for the property.

Cabot L.P. contributed the real estate advisory contracts to Cabot Advisors,
Inc. (Cabot Advisors) and received 100% of the non-voting preferred stock of
Cabot Advisors, which entitles it to 95% of Cabot Advisors' net operating cash
flow. All of the common stock of Cabot Advisors is owned by an officer of Cabot
Trust.

At December 31, 1999, Cabot Trust owned 93.0% of Cabot L.P. Cabot Trust owned
42.7% of Cabot L.P. at December 31, 1998.

During the year ended December 31, 1999, Cabot L.P. issued 177,448 Units in
conjunction with acquisitions.

The Offerings

On February 4, 1998, Cabot Trust completed the offering of 8,625,000 Common
Shares at an offering price of $20.00 per share. In addition, Cabot Trust issued
1,000,000 Common Shares in a private offering at $20.00 per share (collectively,

Cabot L.P. in exchange for the number of general partnership interests in Cabot
L.P. equal to the number of Common Shares sold in the Offerings.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Cabot
L.P. and its subsidiaries over which it exercises control. All significant
intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Investment in Real Estate

Investments in real estate are carried at cost, less accumulated depreciation.
It is Cabot L.P.'s policy to review the carrying value of long-lived assets for
impairment whenever events or changes in circumstances indicate that the
carrying value of such assets may not be recoverable. Measurement of the
impairment loss is based on the fair value of the asset. Generally, fair value
is determined using valuation techniques such as the present value of expected
future cash flows. No impairment adjustments have been made as a result of this
review process during 1999 or 1998.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)
                                December 31, 1999

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Investments in real estate are primarily depreciated over 40 years using the
straight-line method. Expenditures for ordinary maintenance and repairs are
charged to operations as incurred. Significant building renovations and
improvements that extend the useful life of or improve the assets are
capitalized.

Cash Equivalents

Cabot L.P. considers all short-term investments with a maturity of three months
or less to be cash equivalents.

Capitalization of Costs

Cabot L.P. has capitalized as deferred costs certain expenditures related to the
financing and leasing of its properties. Capitalized loan fees are amortized
over the term of the related loans and lease acquisition costs are amortized
over the term of the related leases, or the estimated useful life of the
improvement, if shorter. Deferred Lease Acquisition Costs and Deferred Financing
Costs included in the accompanying consolidated balance sheets are presented net
of accumulated amortization totaling $8,620,000 and $1,413,000, respectively, as
of December 31, 1999 and $3,487,000 and $466,000, respectively, as of December
31, 1998.

Investment in Cabot Advisors

Cabot L.P.'s investment in Cabot Advisors is accounted for using the equity
method. Under the equity method of accounting, Cabot L.P.'s pro rata share of
Cabot Advisors' income (loss) is recorded as an increase (decrease) in the
carrying value of its investment and any distributions received are recorded as
decreases in the carrying value.

Rental Income

All leases are classified as operating leases. Certain leases provide for tenant
occupancy during periods for which no rent is due and minimum rent payments that
increase during the term of the lease. Cabot L.P. records rental income for the
full term of each lease on a straight-line basis. The resulting Deferred Rent
Receivable represents the amount due from tenants, net of reserves, which Cabot
L.P. expects to collect over the remaining life of the leases rather than
currently. Deferred rental revenue is not recognized for income tax purposes
until received. Cabot L.P. recorded a provision for uncollectible rental income
of $352,000 and $312,000 in 1999 and 1998, respectively, and wrote off $90,000
against its Allowance for Uncollectible Accounts in 1999.

Interest Rate Protection Agreements

Cabot L.P. uses various types of interest rate protection agreements from time
to time to manage its exposures to interest rate risk. During 1999 and 1998,
Cabot L.P. used interest rate collar agreements and interest rate cap agreements
to manage a portion of the interest rate risk arising from its LIBOR-based
acquisition facility and may, in the future, use other types of agreements. The
collar agreements effectively limited the LIBOR interest cost of a portion of
the outstanding balance on the acquisition facility to a specified interest rate
range by requiring Cabot L.P.'s counter party to pay amounts to Cabot L.P. to
the extent LIBOR increased above the ceiling of


                                       41

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

the specified range and requiring Cabot L.P. to make payments to the counter
party to the extent LIBOR declined below the floor of the range. The interest
rate cap agreements limited the LIBOR interest cost of a portion of the
outstanding balance on the acquisition facility to a maximum interest rate by
requiring Cabot L.P.'s counter party to pay amounts to Cabot L.P. to the extent
LIBOR increased above the ceiling as specified. Cabot L.P. accounts for such
agreements on the accrual method. Amounts to be received from or paid to the
counter parties of the agreements are accrued during the period to which the
amounts relate and are reflected as increases or decreases in interest expense.
The related amounts payable to the counter parties are included in accounts
payable in the accompanying balance sheets.

During 1998, Cabot L.P. entered into an interest rate hedge transaction
(referred to as a Treasury Lock) involving the future sale of $100.0 million of
Treasury securities based on a rate of approximately 5.54% for such securities
in anticipation of a future debt issuance of at least $100.0 million with a
maturity of 10 years. At the March 31, 1999 contractual settlement date for this
transaction, Cabot L.P. paid $2.5 million to its counter party in the
transaction, reflecting the decrease in Treasury security yields since the July
1998 commencement of the transaction. Because an offering of the size and
maturity contemplated when the interest rate hedge transaction was executed was
not completed by the time of, or shortly after, the March 31, 1999 settlement
date of the transaction, Cabot L.P. recorded a loss of $2.5 million in the year
ended December 31, 1999.

Recent Accounting Pronouncements

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, Accounting for Derivative
Instruments and Hedging Activities. In June 1999, the FASB issued SFAS No. 137
which deferred the effective date of SFAS No. 133. The statement is now
effective for fiscal years beginning after June 15, 2000; earlier adoption is
allowed. This statement requires companies to record derivatives on the balance
sheet as assets or liabilities, measured at fair value. Gains or losses
resulting from changes in the values of those derivatives would be accounted for
depending on the use of the derivative and whether it qualifies for hedge
accounting. Cabot L.P. is currently evaluating the impact of this statement and
does not anticipate a material effect on its results of operations or financial
position resulting from the adoption of SFAS No. 133, as amended by SFAS No.
137, due to its relatively limited use of derivative instruments.

3. ACQUISITIONS OF REAL ESTATE INVESTMENTS

In accordance with generally accepted accounting principles, Cabot L.P. has
accounted for the Formation Transactions using the purchase method of
accounting. As such, the assets acquired and liabilities assumed in connection
with the Formation Transactions are recorded at the fair value of the
consideration surrendered and liabilities assumed, except for the net assets
contributed by Cabot Partners, the sponsor and organizer, which were recorded at
their historical

Subsequent to the Formation Transactions, Cabot L.P. acquired 84 properties
during 1998 with an aggregate of approximately 9.6 million net rentable square
feet. The aggregate purchase price for the 84 properties was $426.2 million,
including $44.0 million of debt assumed and issuance of $2.3 million in Units of
Cabot L.P.

During 1999, Cabot L.P. acquired 113 properties with an aggregate of
approximately 10.0 million net rentable square feet. The aggregate purchase
price for the 113 properties was $448.3 million, including $28.2 million of debt
assumed and issuance of $3.4 million in Units in Cabot L.P.

4. DEBT FACILITIES

The Acquisition Facility

On March 16, 1998, Cabot L.P. obtained a $325 million unsecured revolving line
of credit facility (the Acquisition Facility). The Acquisition Facility matures
on March 16, 2001 and the

4. DEBT FACILITIES (CONTINUED)

interest rate for 1999 was LIBOR plus 100 basis points. At December 31, 1999 and
1998, outstanding borrowings under the Acquisition Facility were $163 million
and $200 million, respectively, and the interest rate was 7.50% and 6.60%,
respectively. The weighted average coupon interest rate for the years ended
December 31, 1999 and 1998 was 6.37% and 6.58%, respectively, including the
effect of the interest rate collar and cap arrangements described below. The
Acquisition Facility is used to acquire and develop properties and for working
capital purposes.

Cabot L.P. has entered into an interest rate cap arrangement relating to the
Acquisition Facility for a notional amount of $100 million for the period from
October 1, 1999 through April 1, 2000. This arrangement is intended to result in
limiting the variable nature of the LIBOR component of Cabot L.P.'s interest
rate on an equivalent amount of borrowings to 6.50% per annum. Cabot L.P. also
entered into similar arrangements during 1999 and 1998, which resulted in
interest expense of $86,000 and $47,000, respectively.

Unsecured Debt

On May 4, 1999, Cabot L.P. issued $200 million of senior unsecured redeemable
notes, due May 1, 2004. The notes have a 7.125% coupon interest rate and were
priced at 99.724%, resulting in a discount of $552,000.

Mortgage Debt

Cabot L.P. assumed certain loans in connection with the Formation Transactions,
entered into loan agreements during 1999, and assumed certain loans in
conjunction with several real estate acquisitions, all secured by certain
existing real estate assets (collectively, the Mortgage Loans). The Mortgage
Loans, totaling $163.9 million, bear coupon rates ranging from 7.25% - 9.67% and
are secured by properties with a net book value of $272.6 million. Certain of
the debt assumed in conjunction with the acquisition of properties bears a
coupon interest rate that differed from the fair market value interest rate at
the date of acquisition. In accordance with generally accepted accounting
principles, such debt was recorded at fair market value and interest expense
recorded in the accompanying consolidated statements of operations was adjusted
based on the fair market interest rate at the date of acquisition.

Aggregate principal payments on mortgage notes payable at December 31, 1999 for
the five years ending December 31 and thereafter are as follows:

5. FUTURE MINIMUM RENTS

Future minimum rental receipts due Cabot L.P. on noncancelable operating leases
for the 320 industrial properties as of December 31, 1999 were as follows:

                                                               (in thousands)

      2004.......................................................   51,355
      Thereafter.................................................  143,520

Cabot L.P. is subject to the usual business risks associated with the collection
of the above-scheduled rents. The above amounts do not include additional rental
receipts that will become due as a result of the expense reimbursement and
escalation provisions in the leases. In addition, Cabot L.P.'s minimum future
rental receipts related to nonindustrial properties total $5.9 million.

6. INCOME TAXES

No provision for federal and state income taxes has been recorded relating to
Cabot L.P. as the partners report their respective share of net taxable income
on their individual tax returns.

7. EMPLOYEE BENEFIT PLANS

Cabot Trust has adopted the Cabot Industrial Trust Long-Term Incentive Plan (the
LTIP) and the Cabot Industrial Trust 1999 Long-Term Incentive Plan (the 1999
LTIP) (collectively referred to as the Plans), for the purpose of attracting and
retaining highly qualified executive officers, Trustees and employees. The 1999
LTIP is maintained as a broad-based plan within the meaning of the New York
Stock Exchange rules.

The Plans are administered by the Executive Compensation Committee of the Board
of Trustees of Cabot Trust, (the Administrator). Officers and other employees of
Cabot Trust, Cabot L.P. and designated subsidiaries and members of the Board of
Trustees of Cabot Trust who are not employees of Cabot Trust are eligible to
participate.

Options are awarded to Trustees or employees of Cabot Trust in the form of
Common Shares and to employees of Cabot L.P. or Cabot Advisors in the form of
Units. The LTIP, at December 31, 1999, authorizes the issuance of up to
4,366,792 Common Shares and Units and the 1999 LTIP authorizes the issuance of
up to 2,000,000 Common Shares and Units. The number of Common Shares and Units
available under the LTIP may increase to an amount equal to 10% of the aggregate
number of outstanding Common Shares and Units. The Plans provide

7. EMPLOYEE BENEFIT PLANS (CONTINUED)

for the grant of (i) Common Share options intended to qualify as incentive
options under Section 422 of the Code (the LTIP only), (ii) Common Share options
and Unit options not intended to qualify as incentive options under Section 422
of the Code and (iii) dividend equivalent rights and distribution equivalent
rights (collectively, "DEUs") which entitle a Participant to be credited with
additional Common Share or Unit rights.

In connection with the grant of options under the Plans, other than options to
nonemployee Trustees, the Administrator determines the terms of the option,
including the option exercise price, any vesting requirements and whether a DEU
shall be awarded. The Administrator has authority to award options at less than
fair market value but at this time has no intention of doing so. The options
granted under the Plans during 1999 and 1998 have 10-year terms and become
exercisable in four equal annual installments commencing on the first
anniversary of the date of grant, subject to acceleration of vesting upon a
change in control of Cabot Trust (as defined in the Plans). DEUs entitle an
option holder to an award of additional shares or units at year end with a
positive intrinsic value calculated using a formula that is based on the
difference, if any, between the annual distribution rate on the Units and Common
Shares versus the average dividend rate on stocks included in the S&P 500 index.
DEUs vest on a vesting schedule as determined by the Administrator and once
vested entitle the holder to a Common Share or Unit at the earlier of the year
of exercise, or the year of expiration, of the underlying option or, in some
cases, only upon a change in control. The options granted in 1998 were generally
awarded with DEUs, which resulted in compensation expense in 1999 of
approximately $475,000.

To the extent an option has not become exercisable at the time of the holder's
termination of employment, it will be forfeited unless the Administrator has
previously exercised its reasonable discretion to make such option exercisable
and all vested options which are not exercised by the expiration date described
in the Plans will be forfeited. Any Common Shares or Units subject to an option
which are forfeited (or which expire without exercise) will again be available
for grant under the Plans.

Pro Forma Stock-based Compensation Expense

In October 1995, the Financial Accounting Standards Board issued SFAS No. 123,
Accounting for Stock-based Compensation, which sets forth a fair-value based
method of recognizing stock-based compensation expense. As permitted by SFAS No.
123, Cabot L.P. has elected to apply APB Opinion No. 25 to account for its
stock-based compensation plans. Accordingly, except for the DEUs as described
above, no compensation cost has been recognized for Cabot Trust's Plans as the
option prices at the date of grant were equal to market prices. Had
compensation cost for awards in 1999 and 1998 under Cabot Trust's Plans been
determined based on the fair value at the grant dates consistent with the
method set forth under SFAS No. 123, the effect on Cabot L.P.'s net income
allocable to partnership units and earnings per unit would have been as
follows:

                                                 1999           1998

                                      (in thousands, except per unit amounts)
Net income allocable to
 partnership units:
     As reported                             $   57,678     $   50,958
     Pro forma                                   55,873         49,761
Basic earnings per unit:
     As reported                             $     1.32     $     1.17
     Pro forma                                     1.28           1.14
Diluted earnings per unit:
     As reported                             $     1.32     $     1.17
     Pro forma                                     1.28           1.14

Pro forma compensation expense for options granted is reflected over the vesting
period; therefore, future pro forma compensation expense may be greater as
additional options are granted.

The weighted average fair value per share/unit of options granted was $2.23 in
1999 and $2.58 in 1998. The fair value of each option grant was estimated on the
grant date using the Black-Scholes option pricing model with the following
weighted-average assumptions:

                                              1999                     1998

7. EMPLOYEE BENEFIT PLANS (CONTINUED)

The Black-Scholes option pricing model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option pricing models require the input of highly
subjective assumptions including expected stock price volatility. Because Cabot
Trust's employee options have characteristics significantly different from those
of traded options and because changes in the subjective input assumptions can
materially affect the fair value estimate, in management's opinion, the existing
models do not necessarily provide a reliable single measure of fair value of its
employee options.

401(k) Savings Plan

The Cabot Savings Plan 401(k) covers eligible full-time employees of Cabot
Trust, Cabot L.P. and their affiliates. Contributions to the plan are made by
both the employee and the employer. Employer contributions are based on the
level of employee contributions. For this plan, Cabot L.P. contributed and
charged to expense $58,000 in 1999 and $44,000 in 1998.

8. EARNINGS PER UNIT

In accordance with SFAS No. 128, Earnings per Share, basic earnings per unit
have been computed by dividing net income allocable to partnership unitholders
by the weighted average number of units outstanding during the period
subsequent to Cabot L.P.'s commencement of operations (see Note 1).

Diluted earnings per unit have been computed considering the potentially
dilutive effect of the exercise of Unit options granted by Cabot L.P. Basic and
diluted earnings per Unit were calculated as follows:

9. FAIR VALUE OF FINANCIAL INSTRUMENTS

Statement of Financial Accounting Standards No. 107, Disclosures about Fair
Value of Financial Instruments, requires Cabot L.P. to disclose fair value
information for all financial instruments, for which it is practicable to
estimate fair value, whether or not recognized in the balance sheets. Cabot
L.P.'s financial instruments, other than debt and interest rate protection
agreements are generally short-term in nature and contain minimal credit risk.
These instruments consist of cash and cash equivalents, rents and other
receivables and accounts payable. The carrying amount of these assets and
liabilities in the consolidated balance sheets approximate fair value.

The carrying amount and fair value of Cabot L.P.'s long-term obligations and
off-balance-sheet financial instruments as of December 31, 1999 and 1998 are as
follows:

Long-term obligations:
     Mortgage loans payable                            $(163,866)   $(167,493)   $ (48,206)   $ (51,450)
     Unsecured debt                                    $(200,000)   $(192,480)   $      --    $      --

Off-balance-sheet financial instruments:
     Interest rate protection agreements (liability)   $      --    $       1    $      --    $  (6,734)
</TABLE>

Cabot L.P.'s mortgage loans and unsecured debt are at fixed rates, which in
certain cases differ from borrowing rates currently available to Cabot L.P. with
similar terms and average maturities. The fair market values of mortgage loans
payable were estimated using a valuation technique which discounts expected
future cash flows to net present value. The fair market value of Cabot L.P.'s
unsecured debt was estimated based on publicly quoted market prices, which
represents the amount Cabot L.P. would have to pay to repurchase such borrowings
at year end. Cabot L.P.'s Acquisition Facility is at a variable rate, which
results in a carrying value that approximates its fair value. The fair value of
Cabot L.P.'s interest rate protection agreements is the estimated amount that
Cabot L.P. would receive or pay if it had terminated the contract as of December
31, 1999 or 1998, taking into account the change in interest rates and the
creditworthiness of the counter parties.

11. COMMITMENTS AND CONTINGENCIES

Concentration of Credit Risk

Cabot L.P. maintains its cash and cash equivalents at financial institutions.
The combined account balances at each institution periodically exceed FDIC
insurance coverage and, as a result, there is a concentration of credit risk
related to amounts on deposit in excess of FDIC insurance coverage. Management
of Cabot L.P. believes the risk is not significant.

Environmental

Cabot L.P., as an owner of real estate, is subject to various environmental laws
of federal and local governments. All of Cabot L.P.'s properties were subject to
Phase I Environmental Assessments, which consist of, among other things, a
visual inspection of the property and its neighborhood and a review of pertinent
public records. Compliance by Cabot L.P. with existing laws has not had a
material adverse effect on Cabot L.P.'s consolidated financial condition or
results of operations and management does not believe it will have such a
material adverse effect in the future.

Litigation

Management of Cabot L.P. does not believe there is any litigation threatened
against it other than routine litigation arising out of the ordinary course of

none of which is expected to have a material adverse effect on the consolidated
operating results or financial position of Cabot L.P.

Employment Agreements

Senior executives have entered into employment agreements with Cabot L.P.
Agreements with three of the senior executives are for an initial term of three
years, and each year the term automatically extends an additional year unless
terminated in advance. Agreements with four other senior executives are for an
initial term of two years and each year the term automatically extends an
additional year unless terminated in advance. Each agreement provides for annual
base compensation in amounts ranging from $182,000 to $300,000 ($1,473,000 in
the aggregate in 1999) and an annual cash bonus to be determined by the
Executive Compensation Committee of Cabot Trust's Board of Trustees. The base
annual compensation may be increased in subsequent years by action of the
Executive Compensation Committee. Each of the employment agreements provides for
severance payments in the event of a change in control of Cabot Trust equal to
three times the sum of the current base salary and the annual bonus paid for the
preceding year and also provides for tax reimbursements in certain
circumstances.

                    Report of Independent Public Accountants

To the Partners of
   Cabot Partners Limited Partnership:

We have audited the accompanying balance sheets of Cabot Partners Limited
Partnership as of December 31, 1997 and 1996, and the related statements of
operations, partners' capital and cash flows for the years then ended. These
financial statements are the responsibility of the management of the
Partnership. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Cabot Partners Limited
Partnership as of December 31, 1997 and 1996, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

                          NOTES TO FINANCIAL STATEMENTS
                             (dollars in thousands)

1. ORGANIZATION

Cabot Partners Limited Partnership (the Partnership), a Massachusetts limited
partnership, was formed as of July 11, 1990 to provide a variety of real estate
investment advisory and management services, primarily to a small number of
pension and profit-sharing plans and other institutional investors. Eight
investors represented 70% of fee revenues for 1997 and nine investors
represented 77% of fee revenues for 1996.

The Partnership has two classes of limited partners. The Class A limited
partners contributed cash on a disproportionate basis to their ownership
interest and are entitled to a cumulative guaranteed return on their Adjusted
Capital Contributions, as defined, of 10% through December 31, 1995 and 5%
thereafter, payable only out of available cash. In addition, the Class A limited
partners are entitled to a 5% return of their Adjusted Capital Contributions
prior to distributions of available cash to all the partners in accordance with
their ownership interest. As of December 31, 1997, the cumulative unpaid and
unrecognized return was $2,795.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Income Taxes

No provision for federal and state income taxes has been recorded relating to
the Partnership, as the partners report their respective shares of the net
taxable income on their individual tax returns. The tax basis of assets and
liabilities does not significantly differ from their historical cost basis.

Furniture, Fixtures and Equipment

Furniture and equipment additions are recorded at cost and are depreciated over
an estimated useful life of five years. Fixtures include leasehold improvements
that are recorded at cost and amortized over the shorter of their useful life or
the remaining lease term.

Cost of Investment Advisory Contracts Acquired

The investment advisory contracts acquired are recorded at their fair market
value at the date of acquisition, based on independent appraisals, and are being
amortized over their estimated lives, which range from eight to 16 years.

Allocation of Profits and Losses

Income and losses have been allocated to the partners in accordance with the
provisions of the partnership agreement.

Cash Equivalents

At December 31, 1997, the Partnership had invested excess funds in money market
mutual funds, which have an original maturity of less than three months. For
purposes of the statement of cash flows, this investment has been considered a
cash equivalent.

                             (dollars in thousands)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Pervasiveness of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Fair Value of Financial Instruments

The carrying amounts reported on the accompanying balance sheets for cash and
cash equivalents, receivables, accounts payable and accrued expenses approximate
fair value, due to the short-term nature of these investments.

3. INVESTMENTS

The Partnership owns a 1% managing general partnership interest in a real estate
operating company, CP Private Partners, L.P.-I (Private Partners), and accounts
for this investment under the equity method. Under this method of accounting,
the Partnership's pro rata share of Private Partners' income (loss) is recorded
each year as an increase (decrease) in the carrying value of its investment and
any distributions received are recorded as decreases in the carrying value.

The condensed unaudited historical cost balance sheets of Private Partners at
December 31, 1997 and 1996 is as follows:

                                                             As of December 31,

5. RELATED PARTY TRANSACTIONS

Under two separate agreements, the Partnership provides acquisition, asset
management and property management services to a partnership and a company
separately controlled by two Class A limited partners. The agreements are
cancelable by either party with 30 days notice. After a recent amendment, one
agreement provides for annual fixed fees of $158. The other agreement provides
for an acquisition fee of .25% of acquisition cost and an asset management fee
of 5% of net operating income. The Partnership received acquisition fees from
related parties of $345 for the year ended December 31, 1997, and other related
party fees of $287 and $164 for the years ended December 31, 1997 and 1996,
respectively.

As of December 31, 1997, the Partnership had incurred costs related to the
Formation Transactions described below of $1,225, of which $241 is unpaid and
included in accounts payable and accrued expenses. These costs are to be
reimbursed by Cabot Industrial L.P. subsequent to the Formation Transactions.

6. SUBSEQUENT EVENTS

Formation Transactions

Under the provisions of an agreement executed by the Partnership and several
other investors, Cabot Partners contributed its Advisory Contracts and certain
of its other net assets to Cabot Industrial Properties, L.P. (Cabot L.P.), a
subsidiary partnership of Cabot Industrial Trust (Cabot Trust) and received
1,819,587 Units from Cabot L.P. The units are convertible into common shares of
Cabot Trust on a one-to-one basis subject to certain limitations. As of February
4, 1998, the common shares had a fair market value of $20 per share. The
remainder of the Partnership's net assets will be distributed to its partners.
The impact of these proposed transactions is not reflected in the accompanying
financial statements.

The cumulative unpaid and unrecognized return discussed in Note 1 was settled
through these distribution of Units received in conjunction with these
transactions.

Sales of Assets Under Management

Under the terms of the investment advisory agreements, investors have the right
to terminate the Partnership as advisor with 30 days notice. In addition, a
significant portion of the Partnership's assets under management may be
transferred to other advisors or sold as a part of the investor's investment
strategy.

During 1997, all the properties of three portfolios have been sold. These
portfolios accounted for advisory and property management fees of $2,985 and
$3,249 for the years ended December 31, 1997 and 1996, respectively.

partnership" within the meaning of Section 7704 of the Code. Capitalized terms
used herein and not otherwise defined herein shall have the meanings ascribed to
them in the Partnership Agreement.

            Section 2. Designation and Number. A series of Partnership Units in
the Partnership designated as the "8.625% Series B Cumulative Redeemable
Preferred Units" (the "Series B Preferred Units") is hereby established. The
number of Series B Preferred Units shall be 1,300,000.

            Section 3. Distributions. (a) Payment of Distributions. Subject to
the rights of holders of Parity Preferred Units as to the payment of
distributions, pursuant to Section 5.1 of the Partnership Agreement, holders of
Series B Preferred Units shall be entitled to receive, when, as and if declared
by the Partnership acting through the General Partner, out of Available Cash,
cumulative preferential cash distributions at the rate per annum of 8.625% of
the original Capital Contribution per Series B Preferred Unit. In the event that

shall have an unconditional, published, Standard & Poor's rating of at least
"BBB" and (ii) neither Moody's nor any other rating agency with offices located
in at least five (5) cities in the United States shall have in effect an
unconditional, published, rating of the General Partner's senior unsecured debt
which is lower than its rating for such senior unsecured debt as of the date
hereof, then beginning on the date on which each of such foregoing conditions
are met, the rate per annum shall be 8.50% of the original Capital Contribution
per Series B Preferred Unit, in which case the designation of the Series B
Preferred Units will change accordingly to reflect such new distribution rate;
provided, that, if (y) either Moody's or any other rating agency with offices
located in at least five (5) cities in the United States shall have in effect on
December 31, 1999 an unconditional published rating of the General Partner's
senior unsecured debt which is lower than its rating of such senior unsecured
debt as of the date hereof or (z) a Standard & Poor's rating of at least "BBB"
shall no longer be in effect on December 31, 1999, then the revised rate herein
provided shall be void ab initio and the General Partner shall pay on December
31, 1999, in addition to the distribution due to the holders of the Series B
Preferred Units, the difference between (1) the dividend that would have accrued
at the original rate of 8.625% per annurn during the current and any prior
quarterly distribution period and (2) the distribution that actually accrued
during such distribution periods at the voided rate of 8.50% per annum. Promptly
after January 1, 2000 the parties hereto shall execute, acknowledge and deliver
or cause to be executed acknowledged and delivered all instruments and documents
as may be reasonably necessary or desirable to memorialize the revised
distribution rate. Such distributions shall be cumulative, shall accrue from the
original date of issuance and will be payable (i) quarterly in arrears, on March
31, June 30, September 30 and December 31 of each year commencing on June 30,
1999 and, (ii), in the event of (A) an exchange of Series B Preferred Units into
Series B Preferred Shares, or (B) a redemption of

                                       2
<PAGE>

Series B Preferred Units, on the exchange date or redemption date, as applicable
(each a "Preferred Unit Distribution Payment Date"). The amount of the
distribution payable for any period will be computed on the basis of a 360-day
year of twelve 30-day months and for any period shorter than a full quarterly
period for which distributions are computed, the amount of the distribution
payable will be computed on the basis of the actual number of days elapsed in
such period. If any date on which distributions are to be made on the Series B
Preferred Units is not a Business Day (as defined herein), then payment of the
distribution to be made on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other payment in respect of
any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.
Distributions on the Series B Preferred Units will be made to the holders of
record of the Series B Preferred Units on the relevant record dates to be fixed
by the Partnership acting through the General Partner, which record dates shall
in no event exceed fifteen (15) Business Days prior to the relevant Preferred
Unit Distribution Payment Date (the "Preferred Unit Partnership Record Date").

            The term "Business Day" shall mean each day other than a Saturday or
a Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulations or executive order to close.

      (b) Distributions Cumulative. Distributions on the Series B Preferred
Units will accrue whether or not the terms and provisions of any agreement of
the Partnership, including any agreement relating to its indebtedness at any
time prohibit the current payment of distributions, whether or not the
Partnership has earnings, whether or not there are funds legally available for
the payment of such of such distributions and whether or not such distributions
are authorized. Accrued but unpaid distributions on the Series B Preferred Units
will accumulate as of the Preferred Unit Distribution Payment Date on which they
first become payable. Distributions on account of arrears for any past
distribution periods may be declared and paid at any time, without reference to
a regular Preferred Unit Distribution Payment Date to holders of record of the
Series B Preferred Units on the record date fixed by the Partnership acting
through the General Partner which date shall not exceed fifteen (15) Business
Days prior to the payment date. Accumulated and unpaid distributions will not
bear interest.

      (c) Priority as to Distributions. (i) So long as any Series B Preferred
Units are outstanding, no distribution of cash or other property shall be
authorized, declared, paid or set apart for payment on or with respect to any
class or series of Partnership Interest of the Partnership ranking junior as to
the payment of distributions or rights upon a voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership to the Series B
Preferred Units (collectively, "Junior Units"), nor shall any cash or other
property be set aside for or applied to the purchase, redemption or other
acquisition for consideration of any Series B Preferred Units, any Parity
Preferred Units or any Junior Units, unless, in each case, all distributions
accumulated on all Series B Preferred Units and all classes and series of
outstanding Parity Preferred Units have been paid in full. The foregoing
sentence will not prohibit (a) distributions payable solely in Partnership Units
ranking junior to the Series B Preferred Units as

                                       3
<PAGE>

to distributions and upon liquidation, winding-up or dissolution, (b) the
conversion of Junior Units or Parity Preferred Units into Partnership Units
ranking junior to the Series B Preferred Units as to distributions and upon
liquidation, winding-up or dissolution or (c) the redemption of Partnership
Interests corresponding to any Series B Preferred Shares (as hereinafter
defined), Parity Preferred Shares (as such term is defined in the Charter) or
Junior Shares (as such term is defined in the Charter) to be purchased by the
General Partner pursuant to Article 3 of the Declaration of Trust of the General
Partner (the "Charter") to preserve the General Partner's status as a real
estate investment trust, provided that such redemption shall be upon the same
terms as the corresponding purchase pursuant to Article 3 of the Charter.

            (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series B Preferred Units, all distributions authorized and
declared on the Series B Preferred Units and all classes or series of
outstanding Parity Preferred Units shall be authorized and declared so that the
amount of distributions authorized and declared per Series B Preferred Unit and
such other classes or series of Parity Preferred Units shall in all cases bear
to each other the same ratio that accrued distributions per Series B Preferred
Unit and such other classes or series of Parity Preferred Units (which shall not
include any accumulation in respect of unpaid distributions for prior
distribution periods if such class or series of Parity Preferred Units do not
have cumulative distribution rights) bear to each other.

      (d) No Further Rights. Holders of Series B Preferred Units shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

            Section 4. Allocations. Sections 6.1(a) and 6.1(b)are hereby deleted
and replaced by the following:

      (a) Net Income. After giving effect to the special allocations set forth
in Section 6.2 through Section 6.4 below, Net Income shall be allocated:

            (i)   first, to the General Partner to the extent that Net Losses
                  previously allocated to the General Partner pursuant to
                  Section 6.1(b)(iii) below for all prior taxable years exceed
                  Net Income previously allocated to the General Partner
                  pursuant to this Section 6.1(a)(i) for all prior taxable
                  years,

            (ii)  second, to Partners holding any Partnership Interests that are
                  entitled to any preference in distribution to the extent that
                  Net Losses previously allocated to such holders pursuant to
                  Section 6.1(b)(ii) below for all prior taxable years exceed
                  Net Income previously allocated to such Partners pursuant to
                  this Section 6.1(a)(ii) for all prior taxable years,

            (iii) third, to Partners holding Partnership Units of a class not
                  entitled to

                                       4
<PAGE>

                  preference in distribution to the extent that Net Losses
                  previously allocated to such holders pursuant to Section
                  6.1(b)(i) below for all prior taxable years exceed Net Income
                  previously allocated to such holders pursuant to this Section
                  6.1(a)(iii) for all prior taxable years,

            (iv)  fourth, to Partners holding any Partnership Interests that are
                  entitled to any preference in distribution in accordance with
                  the rights of any such class of Partnership Interests until
                  each such Partnership Interest has been allocated, Net Income
                  equal to the excess of (x) the cumulative amount of preferred
                  distributions such Partners are entitled to receive to the
                  last day of the current taxable year or to the date of
                  redemption or exchange, to the extent such Partnership
                  Interests are redeemed or exchanged during such taxable year,
                  over (y) the cumulative Net Income allocated to such Partners,
                  pursuant to this Section 6.1(a)(iv) for all prior taxable
                  years (and, within each such class, pro rata in proportion to
                  the respective share of such Partnership Interests each
                  Partner holds as of the last day of the period for which such
                  allocation is being made), and

            (v)   fifth, with respect to Partnership Units that are not entitled
                  to any preference in the allocation of Net Income, pro rata to
                  each such class in accordance with the terms of such class
                  (and, within each such class, pro rata in proportion to each
                  Partner's respective share of such Partnership Units as of the
                  last day of the period for which such allocation is being
                  made).

      (b) Net Losses. After giving effect to the special allocations set forth
in Section 6.2 through Section 6.4, Net Losses shall be allocated:

            (i)   first, with respect to classes of Partnership Units that are
                  not entitled to any preference in distribution (including the
                  General Partner Interest), pro rata to each such class in
                  accordance with the terms of such class (and, within such
                  class, pro rata in proportion to each Partner's respective
                  share of such Partnership Units as of the last day of the
                  period for which such allocation is being made) until the
                  Adjusted Capital Account (ignoring for this purpose any
                  amounts a Partner is obligated to contribute to the capital of
                  the Partnership or is deemed obligated to contribute pursuant
                  to Regulations Section 1.704-1(b)(2)(ii)(c)(2)) of each
                  Partner with respect to such Partnership Units is reduced to
                  zero,

            (ii)  second, to the Partners holding any Partnership Interests that
                  are entitled to any preference in distribution in accordance
                  with the rights of any such class of Partnership Interests
                  (and, if there is more than one class of such Partnership
                  Interests, then in the reverse order of their preference in
                  distribution), until the Adjusted Capital Account (modified in
                  the same

                                       5
<PAGE>

                  manner as in clause (i)) of each such Partner with respect to
                  such Partnership Interests is reduced to zero, and

            (iii) third, to the General Partner.

            Section 5. Liquidation Proceeds. (a) Upon voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, distributions on the
Series B Preferred Units shall be made in accordance with Section 13.2 of the
Partnership Agreement.

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the
Series B Preferred Units at the respective addresses of such holders as the same
shall appear on the transfer records of the Partnership.

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series B Preferred
Units will have no right or claim to any of the remaining assets of the
Partnership.

      (d) Consolidation, Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all of the property
or assets of the General Partner to, or the consolidation or merger or other
business combination of the Partnership with or into, any corporation, trust,
partnership, limited liability company or other entity (or of any corporation,
trust, partnership, limited liability company or other entity with or into the
Partnership) shall not be deemed to constitute a liquidation, dissolution or
winding-up of the Partnership.

            Section 6. Optional Redemption. (a) Right of Optional Redemption.
The Series B Preferred Units may not be redeemed prior to the fifth (5th)
anniversary of the issuance date. On or after such date, the Partnership shall
have the right to redeem the Series B Preferred Units, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to the Capital Account balance of the holders of Series B Preferred Units (the
"Redemption Price"); provided, however, that no redemption pursuant to this
Section 6 will be permitted if the Redemption Price does not equal or exceed the
original Capital Contribution of such holder plus the cumulative Priority
Return, whether or not declared, to the redemption date to the extent not
previously distributed or distributed pursuant to Section 3(a). If fewer than
all of the outstanding Series B Preferred Units are to be redeemed, the Series B
Preferred Units to be redeemed shall be selected pro rata (as nearly as
practicable without creating factional units).

      (b) Limitation on Redemption. The Partnership may not redeem fewer than
all of the outstanding Series B Preferred Units unless all accumulated and
unpaid distributions have been

                                       6
<PAGE>

paid on all Series B Preferred Units for all quarterly distribution periods
terminating on or prior to the date of redemption.

      (c) Procedures for Redemption. (i) Notice of redemption will be (A) faxed,
and (B) mailed by the Partnership, by certified mail, postage prepaid, not less
than thirty (30) nor more than sixty (60) days prior to the redemption date,
addressed to the respective holders of record of the Series B Preferred Units at
their respective addresses as they appear on the records of the Partnership. No
failure to give or defect in such notice shall affect the validity of the
proceedings for the redemption of any Series B Preferred Units except as to the
holder to whom such notice was defective or not given. In addition to any
information required by law, each such notice shall state: (1) the redemption
date, (2) the Redemption Price, (3) the aggregate number of Series B Preferred
Units to be redeemed and if fewer than all of the outstanding Series B Preferred
Units are to be redeemed, the number of Series B Preferred Units to be redeemed
held by such holder, which number shall equal such holder's pro rata share
(based on the percentage of the aggregate number of outstanding Series B
Preferred Units the total number of Series B Preferred Units held by such holder
represents) of the aggregate number of Series B Preferred Units to be redeemed,
(4) the place or places where such Series B Preferred Units are to be
surrendered for payment of the Redemption Price, (5) that distributions on the
Series B Preferred Units to be redeemed will cease to accumulate on such
redemption date and (6) that payment of the Redemption Price will be made upon
presentation and surrender of such Series B Preferred Units.

            (ii) If the Partnership gives a notice of redemption in respect of
Series B Preferred Units (which notice will be irrevocable) then, by 12:00 noon,
New York City time, on the redemption date, the Partnership will deposit
irrevocably in trust for the benefit of the Series B Preferred Units being
redeemed funds sufficient to pay the applicable Redemption Price and will give
irrevocable instructions and authority to pay such Redemption Price to the
holders of the Series B Preferred Units upon surrender of the Series B Preferred
Units by such holders at the place designated in the notice of redemption. If
the Series B Preferred Units are evidenced by a certificate and if fewer than
all Series B Preferred Units evidenced by any certificate are being redeemed, a
new certificate shall be issued upon surrender of the certificate evidencing all
Series B Preferred Units, evidencing the unredeemed Series B Preferred Units
without cost to the holder thereof. On and after the date of redemption,
distributions will cease to accumulate on the Series B Preferred Units or
portions thereof called for redemption, unless the Partnership defaults in the
payment thereof. If any date fixed for redemption of Series B Preferred Units is
not a Business Day, then payment of the Redemption Price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
is improperly withheld or refused and not paid by the Partnership, distributions
on such Series B Preferred Units will continue to accumulate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
applicable Redemption Price.

                                       7

            Section 7. Voting Rights. (a) General. Holders of the Series B
Preferred Units will not have any voting rights or right to consent to any
matter requiring the consent or approval of the Limited Partners, except as set
forth in the Partnership Agreement and except as set forth below.

      (b) Certain Voting Rights. So long as any Series B Preferred Units remain
outstanding, the Partnership shall not, without the affirmative vote of the
holders of at least two-thirds of the Series B Preferred Units outstanding at
the time (i) authorize or create, or increase the authorized or issued amount
of, any class or series of Partnership Interests senior to the Series B
Preferred Units with respect to payment of distributions or rights upon
liquidation, dissolution or winding-up of the Partnership or reclassify any
Partnership Interests of the Partnership into any such senior Partnership
Interest, or create, authorize or issue any obligations or security convertible
into or evidencing the right to purchase any such senior Partnership Interests,
authorize or create, or increase the authorized or issued amount of any Parity
Preferred Units or reclassify any Partnership Interest into any such Partnership
Interest or create, (ii) authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such Partnership
Interests but only to the extent such Parity Preferred Units are issued to an
Affiliate of the Partnership, other than the General Partner to the extent the
issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates of the
Partnership (or to Affiliates purchasing the preferred stock on the same terms
as nonaffiliated purchasers) or (iii) either (A) consolidate, merge into or
with, or convey, transfer or lease all or substantially all of its assets to,
any corporation or other entity or (B) amend, alter or repeal the provisions of
the Partnership Agreement, whether by merger, consolidation or otherwise, that
would materially and adversely affect the powers, special rights, preferences,
privileges or voting power of the Series B Preferred Units or the holders
thereof; provided, however, that with respect to the occurrence of a merger,
consolidation or a sale or lease of all or substantially all of the
Partnership's assets as an entirety, so long as (1) the Partnership is the
surviving entity and the Series B Preferred Units remain outstanding with the
terms thereof unchanged, or (2) the resulting, surviving or transferee entity is
a partnership, limited liability company or other pass-through entity organized
under the laws of any state and substitutes the Series B Preferred Units for
other interests in such entity having substantially the same terms and rights as
the Series B Preferred Units, including with respect to distributions, voting
rights and rights upon liquidation, dissolution or winding-up of the
Partnership, then the occurrence of any such event shall not be deemed to
materially and adversely affect such rights, privileges or voting powers of the
holders of the Series B Preferred Units and no vote of the Series B Preferred
Units shall be required in such case; and provided further that any increase in
the amount of Partnership Interests or the creation or issuance of any other
class or series of Partnership Interests, in each case ranking (y) junior to the
Series B Preferred Units with respect to payment of distributions or the
distribution of assets upon liquidation, dissolution or winding- up of the
Partnership, or (z) on a parity with the Series B Preferred Units with respect
to payment of distributions and the distribution of assets upon liquidation,
dissolution or winding- up of the Partnership to the extent such Partnership
Interests are issued to an affiliate of the Partnership, other than the General
Partner to the extent the issuance of such interests was to

                                       8
<PAGE>

allow the General Partner to issue corresponding preferred stock to persons who
are not affiliates of the Partnership, shall not be deemed to materially and
adversely affect such rights, preferences, privileges or voting powers and no
vote of the Series B Preferred Units shall be required in such case.

            Section 8. Transfer Restrictions. The Series B Preferred Units shall
be subject to the provisions of Article XI of the Partnership Agreement,
provided, however, that (i) the General Partner shall act reasonably in
exercising its discretion pursuant to the provisions of Section 11.4(a)(ii) to
transferees of Series B Preferred Units, (ii) the provisions of Clause B of
Section 11.3(d) shall not be applicable to holders of Series B Preferred Units
if at the time of such transfer, the Partnership already has 100 Partners; (iii)
if only a portion of the Series B Preferred Units shall be transferred, the
transferee of such transferred Series B Preferred Units shall, subject to the
provisions of Section 11.4, be substituted as a Limited Partner in place of the
transferring holders only as to the Series B Preferred Units so transferred; and
(iv) the provisions of Sections 11.6(c) and 11.6(d) shall not be applicable to
any transfer of Series B Preferred Units; and provided further that "transfer"
when used in Article 11 shall not be deemed to include any exchange pursuant to
Section 9 below.

            Section 9. Exchange Rights. (a) Right to Exchange. (i) Series B
Preferred Units will be exchangeable in whole or in part at anytime on or after
the tenth (10th) anniversary of the date of issuance, at the option of the
holders thereof, for authorized but previously unissued shares of 8.625 % Series
B Cumulative Redeemable Preferred Shares of the General Partner (the "Series B
Preferred Shares") at an exchange rate of one Series B Preferred Share for one
Series B Preferred Unit, subject to adjustment as described below (the "Exchange
Price"), provided that the Series B Preferred Units will become exchangeable at
any time, in whole or in part, at the option of the holders of Series B
Preferred Units for Series B Preferred Shares if (y) at any time full
distributions shall not have been timely made on any Series B Preferred Unit
with respect to six (6) prior quarterly distribution periods, whether or not
consecutive, provided, however, that a distribution in respect of Series B
Preferred Units shall be considered timely made if made within two (2) Business
Days after the applicable Preferred Unit Distribution Payment Date if at the
time of such late payment there shall not be any prior quarterly distribution
periods in respect of which full distributions were not timely made or (z) upon
receipt by a holder or holders of Series B Preferred Units of (1) a notice from
the General Partner that the General Partner or a Subsidiary of the General
Partner has taken the position that the Partnership is, or upon the occurrence
of a defined event in the immediate future will be, a PTP and (2) an opinion
rendered by an outside nationally recognized independent counsel familiar with
such matters addressed to a holder or holders of Series B Preferred Units, that
the Partnership is or likely is, or upon the occurrence of a defined event in
the immediate future will be or likely will be, a PTP. In addition, the Series B
Preferred Units may be exchanged for Series B Preferred Shares, in whole or in
part, at the option of any holder prior to the tenth (10th) anniversary of the
issuance date and after the third (3rd) anniversary thereof if such holder of a
Series B Preferred Units shall deliver to the General Partner either (i) a
private letter ruling addressed to such holder of Series B Preferred Units or
(ii) an opinion of independent counsel reasonably acceptable to the General
Partner based on the enactment of temporary or final

                                       9
<PAGE>

Treasury Regulations or the publication of a Revenue Ruling, in either case to
the effect that an exchange of the Series B Preferred Units at such earlier time
would not cause the Series B Preferred Units to be considered "stock and
securities" within the meaning of section 351(e) of the Code for purposes of
determining whether the holder of such Series B Preferred Units is an
"investment company" under section 721(b) of the Code if an exchange is
permitted at such earlier date. Furthermore, all the Series B Preferred Units
held by any holder thereof which is a real estate investment trust within the
meaning of Sections 856 through 859 of the Code for Series B Preferred Shares
may be exchanged in whole but not in part (but only if the exchange may be
accomplished consistently with the ownership limitations set forth under Article
3 of the Charter (taking into account exceptions thereto)) if at any time, (i)
the Partnership reasonably determines that the assets and income of the
Partnership for a taxable year after 1999 would not satisfy the income and
assets tests of Section 856 of the Code for such taxable year if the Partnership
were a real estate investment trust within the meaning of the Code or (ii) any
such holder of Series B Preferred Units shall deliver to the Partnership and the
General Partner an opinion of independent counsel reasonably acceptable to the
General Partner to the effect that, based on the assets and income of the
Partnership for a taxable year after 1999, the Partnership would not satisfy the
income and assets tests of Section 856 of the Code for such taxable year if the
Partnership were a real estate investment trust within the meaning of the Code
and that such failure would create a meaningful risk that a holder of the Series
B Preferred Units would fail to maintain qualification as a real estate
investment trust.

            (ii) Notwithstanding anything to the contrary set forth in Section
9(a)(i) hereof, if an Exchange Notice (as defined herein) has been delivered to
the General Partner, then the General Partner may, at its option, elect to
redeem or cause the Partnership to redeem all or a portion of the outstanding
Series B Preferred Units for cash in an amount equal to the original Capital
Contribution per Series B Preferred Unit and all accrued and unpaid
distributions thereon to the date of redemption. The General Partner may
exercise its option to redeem the Series B Preferred Units for cash pursuant to
this Section 9(a)(ii) hereof by giving each holder of record of Series B
Preferred Units notice of its election to redeem for cash, within five (5)
Business Days after receipt of the Exchange Notice, by (y) fax, and (z)
registered mail, postage paid, at the address of each holder as it may appear on
the records of the Partnership stating (A) the redemption date, which shall be
no later than sixty (60) days following the receipt of the Exchange Notice, (B)
the redemption price, (C) the place or places where the Series B Preferred Units
are to be surrendered for payment of the redemption price, (D) that
distributions on the Series B Preferred Units will cease to accrue on such
redemption date (E) that payment of the redemption price will be made upon
presentation and surrender of the Series B Preferred Units and (F) the aggregate
number of Series B Preferred Units to be redeemed, and if fewer than all of the
outstanding Series B Preferred Units are to be redeemed, the number of Series B
Preferred Units to be redeemed held by such holder, which number shall equal
such holder's pro-rata share (based on the percentage of the aggregate number of
outstanding Series B Preferred Units the total number of Series B Preferred
Units held by such holder represents) of the aggregate number of Series B
Preferred Units being redeemed.

            (iii) In the event an exchange of all or a portion of Series B
Preferred Units

                                       10
<PAGE>

pursuant to Section 9(a)(i) hereof would violate the provisions on ownership,
limitation of the General Partner set forth in Article 3 of the Charter with
respect to the Series B Preferred Shares, the General Partner shall give written
notice thereof to each holder of record of Series B Preferred Units, within five
(5) Business Days following receipt of the Exchange Notice, by (y) fax, and (z)
registered mail, postage prepaid, at the address of each such holder set forth
in the records of the Partnership. In such event, each holder of Series B
Preferred Units shall be entitled to exchange, pursuant to the provision of
Section 9(b) a number of Series B Preferred Units which would comply with the
provisions on the ownership limitation of the General Partner set forth in such
Article 3 of the Charter and any Series B Preferred Units not so exchanged (the
"Excess Units") shall be redeemed by the Partnership for cash in an amount equal
to the original Capital Contribution per Excess Unit, plus any accrued and
unpaid distributions thereon, whether or not declared, to the date of
redemption. The written notice of the General Partner shall state (A) the number
of Excess Units held by such holder, (B) the redemption price of the Excess
Units, (C) the date on which such Excess Units shall be redeemed, which date
shall be no later than sixty (60) days following the receipt of the Exchange
Notice, (D) the place or places where such Excess Units are to be surrendered
for payment of the Redemption Price, (E) that distributions on the Excess Units
will cease to accrue on such redemption date, and (F) that payment of the
redemption price will be made upon presentation and surrender of such Excess
Units. In the event an exchange would result in Excess Units, as a condition to
such exchange, each holder of such units agrees to provide representations and
covenants reasonably requested by the General Partner relating to (1) the widely
held nature of the interests in such holder, sufficient to assure the General
Partner that the holder's ownership of stock of the General Partner (without
regard to the limits described above) will not cause any individual to
Beneficially Own in excess of the Ownership Limit (all as defined in the General
Partner's Charter); and (2) to the extent such holder can so represent and
covenant without obtaining information from its owners, the holder's ownership
of tenants of the Partnership and its affiliates.

            (iv) The redemption of Series B Preferred Units described in Section
9(a)(ii) and (iii) shall be subject to the provisions of Section 6(b)(i) and
Section 6(c)(ii); provided, however, that the term "Redemption Price" in such
Section shall be read to mean the original Capital Contribution per Series B
Preferred Unit being redeemed plus all accrued and unpaid distributions to the
redemption date.

      (b) Procedure for Exchange. (i) Any exchange shall be exercised pursuant
to a notice of exchange (the "Exchange Notice") delivered to the General Partner
by the holder who is exercising such exchange right, by (A) fax and (B) by
certified mail postage prepaid. The exchange of Series B Preferred Units, or a
specified portion thereof, may be effected after the fifth (5th) Business Day
following receipt by the General Partner of the Exchange Notice by delivering
certificates, if any, representing such Series B Preferred Units to be exchanged
together with, if applicable, written notice of exchange and a proper assignment
of such Series B Preferred Units to the office of the General Partner maintained
for such purpose. Currently, such office is Two Center Plaza, Suite 200, Boston,
Massachusetts 02108. Each exchange will be deemed to have been effected
immediately prior to the close of business on the date on which

                                       11
<PAGE>

such Series B Preferred Units to be exchanged (together with all required
documentation) shall have been surrendered and notice shall have been received
by the General Partner as aforesaid and the Exchange Price shall have been paid.
Any Series B Preferred Shares issued pursuant to this Section 9 shall be
delivered as shares which are duly authorized, validly issued, fully paid and
nonassessable, free of pledge, lien, encumbrance or restriction other than those
provided in the Charter, the Bylaws of the General Partner, the Securities Act
and relevant state securities or blue sky laws.

            (ii) In the event of an exchange of Series B Preferred Units for
Series B Preferred Shares, an amount equal to the accrued and unpaid
distributions, whether or not declared, to the date of exchange on any Series B
Preferred Units tendered for exchange shall (A) accrue on the Series B Preferred
Shares into which such Series B Preferred Units are exchanged, and (B) continue
to accrue on such Series B Preferred Units, which shall remain outstanding
following such exchange, with the General Partner as the holder of such Series B
Preferred Units. Notwithstanding anything to the contrary set forth herein, in
no event shall a holder of a Series B Preferred Unit that was validly exchanged
into Series B Preferred Shares pursuant to this section (other than the General
Partner now holding such Series B Preferred Unit), receive a cash distribution
out of Available Cash of the Partnership, if such holder, after exchange, is
entitled to receive a distribution out of Available Cash with respect to the
Series B Preferred Shares for which such Series B Preferred Unit was exchanged
or redeemed.

            (iii) Fractional shares of Series B Preferred Shares are not to be
issued upon exchange but, in lieu thereof, the General Partner will pay a cash
adjustment based upon the fair market value of the Series B Preferred Shares on
the day prior to the exchange date as determined in good faith by the Board of
Directors of the General Partner.

      (c) Adjustment of Exchange Price. (i) The Exchange Price is subject to
adjustment upon certain events, including, (A) subdivisions, combinations and
reclassification of the Series B Preferred Shares, and (B) distributions to all
holders of Series B Preferred Shares of evidence of indebtedness of the General
Partner or assets (including securities, but excluding dividends and
distributions paid in cash out of equity applicable to Series B Preferred
Shares).

            (ii) In case the General Partner shall be a party to any transaction
(including, without limitation, a merger, consolidation, statutory share
exchange, tender offer for all or substantially all of the General Partner's
capital stock or sale of all or substantially all of the General Partner's
assets), in each case as a result of which the Series B Preferred Shares will be
converted into the right to receive shares of capital stock, other securities or
other property (including cash or any combination thereof), each Series B
Preferred Unit will thereafter be exchangeable into the kind and amount of
shares of capital stock and other securities and property receivable (including
cash or any combination thereof) upon the consummation of such transaction by a
holder of that number of Series B Preferred Shares or fraction thereof into
which one Series B Preferred Unit was exchangeable immediately prior to such
transaction. The General Partner may not become a party to any such transaction
unless the terms thereof are consistent with the foregoing.

                                       12
<PAGE>

            Section 10. No Conversion Rights. (a) The holders of the Series B
Preferred Units shall not have any rights to convert such shares into shares of
any other class or series of shares or into any other securities of, or interest
in, the Partnership.

            (b) The Series B Preferred Units shall not be subject to the
provisions of Section 4.2(e) of the Partnership Agreement.

            Section 11. No Sinking Fund. No sinking fund shall be established
for the retirement or redemption of Series B Preferred Units.

            Section 12. Admission of Limited Partners, Exhibits to Partnership
Agreement. In accordance with Section 12.2(b), Belair and Belcrest are hereby
admitted as Additional Limited Partners. In order to duly reflect the issuance
of Series B Preferred Units provided for herein, the Partnership Agreement is
hereby amended by deleting Exhibit A attached thereto and substituting Exhibit A
attached hereto therefor.

            Section 13. Reaffirmation. Except as modified herein, all terms and
conditions of the Partnership Agreement shall remain in full force and effect,
which terms and conditions the General Partner hereby ratifies and affirms.

                            *          *          *

      IN WITNESS WHEREOF, this Amendment has been executed as of the date first
above written.

            8.625% SERIES B CUMULATIVE REDEEMABLE PREFERRED SHARES

            Cabot Industrial Trust, a Maryland real estate investment trust (the
"Company"), hereby certifies to the State Department of Assessments and Taxation
of Maryland (the "Department") that:

            FIRST: Under a power contained in Article 2, Section 1 of the
Amended and Restated Declaration of Trust of the Company, filed with, and
accepted for record by, the State Department of Assessments and Taxation of
Maryland (the "SDAT") on January 26. 1998. as supplemented by Articles
Supplementary filed with, and accepted for record by. the SDAT on July 10, 1998
(the "Charter"), the Board of Trustees of the Company, as required by Section
8-203(b) of the Corporations and Associations Article of the Annotated Code of
Maryland, has unanimously adopted resolutions classifying and designating
1,300,000 unissued shares of beneficial interest (the "Shares") as 8.625% Series
B Cumulative Redeemable Preferred Shares, with the following preferences,
conversion and other rights, voting powers, restrictions, limitations as to
dividends and other distributions, qualifications and terms and conditions of
redemption, and other terms and conditions, which upon any restatement of the
Charter shall be made part of Article 2 of the Charter, with any necessary or
appropriate changes to the enumeration and lettering thereof:

                  8.625% SERIES B CUMULATIVE REDEEMABLE SHARES

            Section 1. Designation and Number. A series of preferred shares,
designated the "8.625% Series B Cumulative Redeemable Preferred Shares" (the
"Series B Preferred Shares") is hereby established. The number of shares of
Series B Preferred Shares shall be 1,300,000.

            Section 2. Rank. The Series B Preferred Shares shall, with respect
to distributions and rights upon voluntary or involuntary liquidation,
winding-up or dissolution of the Company. rank senior to all classes or series
of common Shares and to all classes or series of equity securities of the
Company now or hereafter authorized, issued or outstanding, other than any class
or series of equity securities of the Company expressly designated as ranking on
a parity with or senior to the Series B Preferred Shares as to distributions and
rights upon voluntary or involuntary liquidation, winding-up or dissolution of
the Company. For purposes of these Articles Supplementary, the term "Parity
Preferred Shares" shall be used to refer to any class or series of equity
securities of the Company now or hereafter authorized, issued or outstanding
expressly designated by the Company to rank on a parity with Series B Preferred
Shares with respect to distributions and rights upon voluntary or involuntary
liquidation, winding-up or dissolution of the Company. The term "equity
securities" does not include debt securities, which will rank senior to the
Series B Preferred Shares prior to conversion.

            Section 3. Distributions. (a) Payment of Distributions. Subject to
the rights of holders of Parity Preferred Shares and holders of equity
securities ranking senior to the Series B Preferred Shares as to payment of
distributions, holders of Series B Preferred Shares will be entitled to receive,
when, as and if declared by the Board of Trustees of the Company, out of funds
legally available for the payment of distributions, cumulative preferential cash
distributions at the rate per annum of 8.625% of the $50 liquidation preference
per Series B Preferred Share. In the event that on or prior to December 31, 1999
(i) the Company's senior unsecured debt shall have an unconditional, published,
Standard & Poor's rating of at least "BBB" and (ii) neither Moody's nor any
other rating agency with offices located in at least five (5) cities in the
United States shall have in effect an unconditional,
<PAGE>

published, rating of the Company's senior unsecured debt which is lower than its
rating for such senior unsecured debt as of the date hereof, then beginning on
the date on which each of such foregoing conditions are met, the rate per annum
shall be 8.50% of the $50 liquidation preference per Series B Preferred Share,
in which case the designation of the Series B Preferred Shares will change
accordingly to reflect such new distribution rate; provided, that, if (y) either
Moody's or any other rating agency with offices located in at least five (5)
cities in the United States shall have in effect on December 31, 1999 an
unconditional published rating of the Company's senior unsecured debt which is
lower than its rating of such senior unsecured debt as of the date hereof or (z)
a Standard & Poor's rating of at least "BBB" shall no longer be in effect on
December 31, 1999, then the revised rate herein provided shall be void ab initio
and the Company shall pay on December 31, 1999, in addition to the dividend then
due to the holders of the Series B Preferred Shares, the difference between (1)
the dividend that would have accrued at the original rate of 8.625% per annum
during the current and any prior quarterly distribution period and (2) the
dividend that actually accrued during such distribution periods at the voided
rate of 8.50% per annum. Promptly after January 1, 2000 the parties hereto shall
execute, acknowledge and deliver or cause to be executed acknowledged and
delivered all instruments and documents as may be reasonably necessary or
desirable to memorialize the revised distribution rate. Such distributions shall
be cumulative, shall accrue from the original date of issuance and will be
payable (i) quarterly in arrears, on March 31, June 30, September 30 and
December 31 of each year commencing on the first of such dates to occur after
the original date of issuance and, (ii) in the event of a redemption, on the
redemption date (each a "Preferred Shares Distribution Payment Date"). The
amount of the distribution payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months and for any period shorter than a full
quarterly period for which distributions are computed, the amount of the
distribution payable will be computed on the basis of the actual number of days
elapsed in such period. If any date on which distributions are to be made on the
Series B Preferred Shares is not a Business Day (as defined herein), then
payment of the distribution to be made on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day is in the next
succeeding calendar year, such payment shall be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date. Distributions on the Series B Preferred Shares will be made to the
holders of record of the Series B Preferred Shares on the relevant record dates,
which, unless otherwise provided by the Company with respect to any
distribution, will be fifteen (15) Business Days prior to the relevant Preferred
Shares Distribution Payment Date (each a "Distribution Record Date").
Notwithstanding anything to the contrary set forth herein, each Series B
Preferred Share shall also continue to accrue all accrued and unpaid
distributions up to the exchange date on any Series B Preferred Unit (as defined
in the Second Amended and Restated Agreement of Limited Partnership of Cabot
Industrial Properties, L.P., dated as of February 4, 1998 (the "Partnership
Agreement"). as amended through the date hereof) validly exchanged into such
Series B Preferred Share in accordance with the provisions of such Partnership
Agreement.

      The term "Business Day" shall mean each day, other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulation or executive order to close.

      (b) Limitation on Distributions. No distributions on the Series B
Preferred Shares shall be declared or paid or set apart for payment by the
Company at such time as the terms and provisions of any agreement of the
Company, including any agreement relating to its indebtedness, prohibits such
declaration, payment or setting apart for payment or provides that such
declaration, payment or setting a part for payment would constitute a breach
thereof or a default thereunder, or if such declaration, payment or setting
apart for payment shall be restricted or prohibited by law.

      (c) Distributions Cumulative. Notwithstanding the foregoing, distributions
on the Series B Preferred Shares will accrue whether or not the terms and
provisions set forth in Section 3(b) hereof at any time prohibit the current
payment of distributions, whether or not the Company has earnings, whether or
not there are funds legally available for the payment of such distributions and
whether or not such distributions are authorized or declared. Accrued but unpaid
distributions on the Series B Preferred Shares will accumulate as of the
Preferred Shares Distribution Payment Date on which they first become payable.
Accumulated and unpaid distributions will not bear interest.
<PAGE>

      (d) Priority as to Distributions. (i) So long as any Series B Preferred
Shares are outstanding, no distribution of cash or other property shall be
authorized, declared, paid or set apart for payment on or with respect to any
class or series of common Shares or any class or series of other Shares of the
Company ranking junior as to the payment of distributions or rights upon
voluntary or involuntary dissolution, liquidation or winding up of the Company
to the Series B Preferred Shares (such common Shares or other junior Shares,
including, without limitation Series A Junior Participating Preferred Shares
authorized pursuant to Articles Supplementary filed with the Department on July
10, 1998, collectively, "Junior Shares"), nor shall any cash or other property
be set aside for or applied to the purchase, redemption or other acquisition for
consideration of any Series B Preferred Shares, any Parity Preferred Shares or
any Junior Shares, unless, in each case, all distributions accumulated on all
Series B Preferred Shares and all classes and series of outstanding Parity
Preferred Shares have been paid in full. The foregoing sentence will not
prohibit (i) distributions payable solely in Shares of the Company ranking
junior to the Series B Preferred Shares as to distributions and upon
liquidation, winding-up or dissolution, (ii) the conversion of Junior Shares or
Parity Preferred Shares into Shares of the Company ranking junior to the Series
B Preferred Shares as to distributions and upon liquidation, windingup or
dissolution, and (iii) purchase by the Company of such Series B Preferred
Shares, Parity Preferred Shares or Junior Shares pursuant to Article 3 of the
Charter to the extent required to preserve the Company's status as a real estate
investment trust.

            (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series B Preferred Shares, all distributions authorized and
declared on the Series B Preferred Shares and all classes or series of
outstanding Parity Preferred Shares shall be authorized and declared so that the
amount of distributions authorized and declared per share of Series B Preferred
Shares and such other classes or series of Parity Preferred Shares shall in all
cases bear to each other the same ratio that accrued distributions per share on
the Series B Preferred Shares and such other classes or series of Parity
Preferred Shares (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Shares do not have cumulative distribution rights) bear to each other.

      (e) No Further Rights. Holders of Series B Preferred Shares shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

            Section 4. Liquidation Preference. (a) Payment of Liquidating
Distributions. Subject to the rights of holders of Parity Preferred Shares and
subject to equity securities ranking senior to the Series B Preferred Shares
with respect to rights upon any voluntary or involuntary liquidation,
dissolution or winding-up of the Company. the holders of Series B Preferred
Shares shall be entitled to receive out of the assets of the Company legally
available for distribution or the proceeds thereof, after payment or provision
for debts and other liabilities of the Company, but before any payment or
distributions of the assets shall be made to holders of common Shares or any
other class or series of shares of the Company that ranks junior to the Series B
Preferred Shares as to rights upon liquidation, dissolution or winding-up of the
Company, an amount equal to the sum of (i) a liquidation preference of $50 per
Series B Preferred Share, and (ii) an amount equal to any accumulated and unpaid
distributions thereon, whether or not declared, to the date of payment. In the
event that, upon such voluntary or involuntary liquidation, dissolution or
winding-up, there are insufficient assets to permit full payment of liquidating
distributions to the holders of Series B Preferred Shares and any Parity
Preferred Shares, all payments of liquidating distributions on the Series B
Preferred Shares and such Parity Preferred Shares shall be made so that the
payments on the Series B Preferred Shares and such Parity Preferred Shares shall
in all cases bear to each other the same ratio that the respective rights of the
Series B Preferred Shares and such other Parity Preferred Shares (which shall
not include any accumulation in respect of unpaid distributions for prior
distribution periods if such Parity Preferred Shares do not have cumulative
distribution rights) upon liquidation, dissolution or winding-up of the Company
bear to each other.
<PAGE>

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Company, stating the payment date
or dates when, and the place or places where, the amounts distributable in such
circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the
Series B Preferred Shares at the respective addresses of such holders as the
same shall appear on the share transfer records of the Company.

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series B Preferred
Shares will have no right or claim to any of the remaining assets of the
Company.

      (d) Consolidation. Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all of the property
or assets of the Company to, or the consolidation or merger or other business
combination of the Company with or into any corporation. trust or other entity
(or of any corporation, trust or other entity with or into the Company) shall
not be deemed to constitute a liquidation, dissolution or winding-up of the
Company.

            Section 5. Optional Redemption. (a) Right of Optional Redemption.
The Series B Preferred Shares may not be redeemed prior to April 29, 2004. On or
after such date, the Company shall have the right to redeem the Series B
Preferred Shares, in whole or in part, at any time or from time to time, upon
not less than thirty (30) nor more than sixty (60) days' written notice, at a
redemption price, payable in cash, equal to $50 per share of Series B Preferred
Shares plus accumulated and unpaid distributions, whether or not declared, to
the date of redemption. If fewer than all of the outstanding Series B Preferred
Shares are to be redeemed, the Series B Preferred Shares to be redeemed shall be
selected pro rata (as nearly as practicable without creating fractional shares).

      (b) Limitation on Redemption. The Company may not redeem fewer than all of
the outstanding shares of Series B Preferred Shares unless all accumulated and
unpaid distributions have been paid on all outstanding Series B Preferred Shares
for all quarterly distribution periods terminating on or prior to the date of
redemption.

      (c) Procedures for Redemption. (i) Notice of redemption will be (i) faxed,
and (ii) mailed by the Company, postage prepaid, not less than thirty (30) nor
more than sixty (60) days prior to the redemption date, addressed to the
respective holders of record of the Series B Preferred Shares to be redeemed at
their respective addresses as they appear on the transfer records of the
Company. No failure to give or defect in such notice shall affect the validity
of the proceedings for the redemption of any Series B Preferred Shares except as
to the holder to whom such notice was defective or not given. In addition to any
information required by law or by the applicable rules of any exchange upon
which the Series B Preferred Shares may be listed or admitted to trading, each
such notice shall state: (i) the redemption date, (ii) the redemption price,
(iii) the number of Series B Preferred Shares to be redeemed, (iv) the place or
places where such Series B Preferred Shares are to be surrendered for payment of
the redemption price, (v) that distributions on the Series B Preferred Shares to
be redeemed will cease to accumulate on such redemption date and (vi) that
payment of the redemption price and any accumulated and unpaid distributions
will be made upon presentation and surrender of such Series B Preferred Shares.
If fewer than all of the Series B Preferred Shares held by any holder are to be
redeemed, the notice mailed to such holder shall also specify the number of
Series B Preferred Shares held by such holder to be redeemed.

            (ii) If the Company gives a notice of redemption in respect of
Series B Preferred Shares (which notice will be irrevocable) then, by 12:00
noon, New York City time, on the redemption date, the Company will deposit
irrevocably in trust for the benefit of the holders of the Series B Preferred
Shares being redeemed, funds sufficient to pay the applicable redemption price,
plus any accumulated and unpaid distributions, whether or not
<PAGE>

declared, if any, on such shares to the date fixed for redemption, without
interest, and will give irrevocable instructions and authority to pay such
redemption price and any accumulated and unpaid distributions, whether or not
declared, if any, on such shares to the holders of the Series B Preferred Shares
upon surrender of the certificates for the Series B Preferred Shares by such
holders at the place designated in the notice of redemption. If fewer than all
Series B Preferred Shares evidenced by any certificate are being redeemed, a new
certificate shall be issued upon surrender of the certificate evidencing all
Series B Preferred Shares, evidencing the unredeemed Series B Preferred Shares
without cost to the holder thereof. On and after the date of redemption,
distributions will cease to accumulate on the Series B Preferred Shares or
portions thereof called for redemption, unless the Company defaults in the
payment thereof. If any date fixed for redemption of Series B Preferred Shares
is not a Business Day, then payment of the redemption price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day. in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the redemption price
or any accumulated or unpaid distributions in respect of the Series B Preferred
Shares is improperly withheld or refused and not paid by the Company,
distributions on such Series B Preferred Shares will continue to accumulate from
the original redemption date to the date of payment, in which case the actual
payment date will be considered the date fixed for redemption for purposes of
calculating the applicable redemption price and any accumulated and unpaid
distributions.

            (e) Status of Redeemed Shares. Any Series B Preferred Shares that
shall at any time have been redeemed shall after such redemption, have the
status of authorized but unissued Shares, without designation as to class or
series until such shares are once more designated as part of a particular class
or series by the Board.

            Section 6. Voting Rights. (a) General. Holders of the Series B
Preferred Shares will not have any voting rights, except as set forth below.

      (b) Right to Elect Trustees. (i) If at any time full distributions shall
not have been timely made on any Series B Preferred Shares with respect to any
six (6) prior quarterly distribution periods, whether or not consecutive, (a
"Preferred Distribution Default"), the holders of such Series B Preferred
Shares, voting together as a single class with the holders of each class or
series of Parity Preferred Shares upon which like voting rights have been
conferred and are exercisable, will have the right to elect two additional
Trustees to serve on the Company's Board (the "Preferred Shares Trustees") at a
special meeting called by the holders of record of at least 10% of the
outstanding Series B Preferred Shares or any such class or series of Parity
Preferred Shares or at the next annual meeting of Shareholders, and at each
subsequent annual meeting of Shareholders or special meeting for the election of
Trustees held in place thereof until all such distributions in arrears and
distributions for the current quarterly period on the Series B Preferred Shares
and each such class or series of Parity Preferred Shares have been paid in full.

            (ii) At any time when such voting rights shall have vested, a proper
officer of the Company shall call or cause to be called, upon written request of
holders of record of at least 10% of the outstanding Series B Preferred Shares,
a special meeting of the holders of Series B Preferred Shares and all the series
of Parity Preferred Shares upon which like voting rights have been conferred and
are exercisable (collectively, the "Parity Securities") by mailing or causing to
be mailed to such holders a notice of such special meeting to be held not less
than ten and not more than 45 days after the date such notice is given. The
record date for determining holders of the Parity Securities entitled to notice
of and to vote at such special meeting will be the close of business on the
third Business Day preceding the day on which such notice is mailed. At any such
special meeting, all of the holders of the Parity Securities, by plurality vote,
voting together as a single class without regard to series will be entitled to
elect two Trustees on the basis of one vote per $25.00 of liquidation preference
to which such Parity Securities are entitled by their terms (excluding amounts
in respect of accumulated and unpaid dividends) and not cumulatively. The holder
or holders of one-third of the Parity Securities then outstanding, present in
person or by proxy, will constitute a
<PAGE>

quorum for the election of the Preferred Shares Trustees except as otherwise
provided by law. Notice of all meetings at which holders of the Series B
Preferred Shares shall be entitled to vote will be given to such holders at
their addresses as they appear in the transfer records. At any such meeting or
adjournment thereof in the absence of a quorum, subject to the provisions of any
applicable law, a majority of the holders of the Parity Securities present in
person or by proxy shall have the power to adjourn the meeting for the election
of the Preferred Shares Trustees, without notice other than an announcement at
the meeting. until a quorum is present. If a Preferred Distribution Default
shall terminate after the notice of a special meeting has been given but before
such special meeting has been held, the Company shall, as soon as practicable
after such termination, mail or cause to be mailed notice of such termination to
holders of the Series B Preferred Shares that would have been entitled to vote
at such special meeting.

            (iii) If and when all accumulated distributions and the
distributions for the current distribution period on the Series B Preferred
Shares shall have been paid in full or a sum sufficient for such payment is
irrevocably deposited in trust for payment, the holders of the Series B
Preferred Shares shall be divested of the voting rights set forth in this
Section 6(b) herein (subject to revesting in the event of each and every
Preferred Distribution Default) and, if all distributions in arrears and the
distributions for the current distribution period have been paid in full or set
aside for payment in full on all other classes or series of Parity Preferred
Shares upon which like voting rights have been conferred and are exercisable,
the term and office of each Preferred Shares Trustee so elected shall terminate.
Any Preferred Shares Trustee may be removed at any time with or without cause by
the vote of, and shall not be removed otherwise than by the vote of, the holders
of record of a majority of the outstanding Parity Securities when they have the
voting rights set forth in this Section 6(b). So long as a Preferred
Distribution Default shall continue, any vacancy in the office of a Preferred
Shares Trustee may be filled by written consent of the Preferred Shares Trustee
remaining in office, or if none remains in office, by a vote of the holders of
record of a majority of the outstanding Parity Securities when they have the
voting rights set forth in this Section 6(b). The Preferred Shares Trustees
shall each be entitled to one vote per trustee on any matter.

      (c) Certain Voting Rights. So long as any Series B Preferred Shares remain
outstanding. the Company shall not, without the affirmative vote of the holders
of at least two thirds of the Series B Preferred Shares outstanding at the time
(i) designate or create, or increase the authorized or issued amount of, any
class or series of shares ranking senior to or on parity with the Series B
Preferred Shares with respect to payment of distributions or rights upon
liquidation, dissolution or winding-up of the Company or reclassify any
authorized shares of the Company into any such shares, or create, authorize or
issue any obligations or security convertible into or evidencing the right to
purchase any such shares, (ii) designate or create, or increase the authorized
or issued amount of, any Parity Preferred Shares or reclassify any authorized
shares of the Company into any such shares, or create, authorize or issue any
obligations or security convertible into or evidencing the right to purchase any
such shares, but only to the extent such Parity Preferred Shares are issued to
an affiliate of the Company, or (iii) either (A) consolidate, merge into or
with, or convey, transfer or lease its assets substantially as an entirety. to
any corporation or other entity. or (B) amend, alter or repeal the provisions of
the Company's Charter (including these Articles Supplementary) or By-laws,
whether by merger, consolidation or otherwise, in each case that would
materially and adversely affect the powers, special rights, preferences,
privileges or voting power of the Series B Preferred Shares or the holders
thereof; provided, however, that with respect to the occurrence of a merger,
consolidation or a sale or lease of all or substantially all of the Company's
assets as an entirety, so long as (a) the Company is the surviving entity and
the Series B Preferred Shares remain outstanding with the terms thereof
unchanged, or (b) the resulting, surviving or transferee entity is a corporation
organized under the laws of any state and substitutes the Series B Preferred
Shares for other preferred Shares having substantially the same terms and same
rights as the Series B Preferred Shares, including with respect to
distributions, voting rights and rights upon liquidation, dissolution or
winding-up of the Company, then the occurrence of any such event shall not be
deemed to materially and adversely affect such rights, privileges or voting
powers of the holders of the Series B Preferred Shares and no vote of the Series
B Preferred Shares shall be required; and provided further that any increase in
the amount of authorized Shares or the creation or issuance of any other class
or series of Shares, or any increase in an amount of authorized shares of each
class or series, in each case ranking either (a) junior to the Series B
Preferred Shares with respect to payment of distributions and the distribution
of assets upon liquidation, dissolution or winding-up of the Company, or (b) on
a parity with the Series B Preferred Shares with respect to payment of
<PAGE>

distributions or the distribution of assets upon liquidation, dissolution or
winding-up of the Company to the extent such Shares are not issued to an
affiliate of the Company, shall not be deemed to materially and adversely affect
such rights, preferences, privileges or voting powers and no vote of the Series
B Preferred Shares shall be required.

            Section 7. Transfer Restrictions. The Series B Preferred Shares
shall be subject to the provisions of Article 3 of the Charter; provided,
however, in no event shall the Ownership Limit with respect to the Series B
Preferred Shares (as defined in the Charter) be decreased pursuant to Section 10
of Article 3 of the Charter or otherwise (other than a decrease as a result of a
retroactive change in existing law that would require a decrease to retain real
estate investment trust status under the Internal Revenue Code of 1986, as
amended).

            Section 8. No Conversion Rights. The holders of the Series B
Preferred Shares shall not have any rights to convert such shares into shares of
any other class or series of Shares or into any other securities of, or interest
in. the Company.

            Section 9. No Sinking Fund. No sinking fund shall be established for
the retirement or redemption of Series B Preferred Shares.

            Section 10. No Preemptive Rights. No holder of the Series B
Preferred Shares of the Company shall, as such holder, have any preemptive
rights to purchase or subscribe for additional Shares of the Company or any
other security of the Company which it may issue or sell.

            FOURTH: The Series B Preferred Shares have been classified and
designated by the Board under the authority contained in the Charter.

            FIFTH: These Articles Supplementary have been approved by the Board
in the manner and by the vote required by law.

Articles Supplementary to be the corporate act of the Company and, as to all
matters or facts required to be verified under oath, the undersigned President

                                SECOND AMENDMENT
                                       TO
                           SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                        CABOT INDUSTRIAL PROPERTIES, L.P.

      THIS SECOND AMENDMENT TO SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED
PARTNERSHIP (this "Amendment") dated as of September 3, 1999, is entered into by
CABOT INDUSTRIAL TRUST, a Maryland real estate investment trust, as general
partner (the "General Partner") of CABOT INDUSTRIAL PROPERTIES, L.P. (the
"Partnership"), for itself and on behalf of the limited partners of the
Partnership, and ________________ ("Contributor").

      WHEREAS, Section 4.2(a) of the Second Amended and Restated Agreement of
Limited Partnership of the Partnership (the "Partnership Agreement") authorizes
the General Partner to cause the Partnership to issue additional Partnership
Units in one or more classes or series, with such designations, preferences and
relative, participating, optional or other special rights, powers and duties as
shall be determined by the General Partner, subject to the provisions of such
section; and

      WHEREAS, pursuant to the authority granted to the General Partner pursuant
to Sections 4.2(a) and 14.1(b) of the Partnership Agreement, the General Partner
desires to amend the Partnership Agreement (i) to establish a new class of
Partnership Units, the Series C Preferred Units (as hereinafter defined), and to
set forth the designations, rights, powers, preferences and duties of such
Series C Preferred Units, (ii) to issue the Series C Preferred Units to
Contributor and admit Contributor as an Additional Limited Partner and (iii) to
make certain other changes to the Partnership Agreement.

      WHEREAS, Contributor intends to transfer its Series C Preferred Units to
________ LLC Delaware limited liability company ("LLC"), whereupon reference
herein to Contributor shall be deemed to be references to LLC.

      NOW, THEREFORE, in consideration of good and valuable consideration, the
receipt and sufficiency of which hereby are acknowledged, the General Partner
hereby amends the Partnership Agreement as follows:

      Section 1. Definitions. For purposes of this Amendment, the term "Parity
Preferred Units" shall be used to refer to any class or series of Partnership
Interests of the Partnership now or hereafter authorized, issued or outstanding
expressly designated by the Partnership to rank on a parity with Series C
Preferred Units with respect to distributions and rights upon voluntary or
involuntary liquidation, winding-up or dissolution of the Partnership. The term
"Priority Return" shall mean, an amount equal to 8.625% per annum, determined on
the basis of a 360 day year of twelve 30 day months, cumulative to the extent
not distributed for any given
<PAGE>

distribution period pursuant to Section 5.1 of the Partnership Agreement, of the
stated value of $25 per Series C Preferred Unit, commencing on the date of
issuance of such Series C Preferred Unit. The term "Subsidiary" shall mean with
respect to any person, any corporation, partnership, limited liability company,
joint venture or other entity of which a majority of(i) voting power of the
voting equity securities or (ii) the outstanding equity interests, is owned,
directly or indirectly, by such person. The term "PTP" shall mean a "publicly
traded partnership" within the meaning of Section 7704 of the Code. Capitalized
terms used herein and not otherwise defined herein shall have the meanings
ascribed to them in the Partnership Agreement. The term "Preferred Limited
Partner" means any Person holding a Preferred Unit, and named as a Preferred
Limited Partner in Exhibit A attached hereto, as such Exhibit may be amended
from time to time, or any Substituted Limited Partner or Additional Limited
Partner, in such Person's capacity as a Preferred Limited Partner in the
Partnership.

      Section 2. Designation and Number. A series of Partnership Units in the
Partnership designated as the "8.625% Series C Cumulative Redeemable Preferred
Units" (the "Series C Preferred Units") is hereby established. The number of
Series C Preferred Units shall be for 2,600,000.

      Section 3. Distributions. (a) Payment of Distributions. Subject to the
rights of holders of Parity Preferred Units as to the payment of distributions,
pursuant to Section 5.1 of the Partnership Agreement, holders of Series C
Preferred Units shall be entitled to receive, when, as and if declared by the
Partnership acting through the General Partner, out of Available Cash,
cumulative preferential cash distributions at the rate per annum of 8.625% of
the original Capital Contribution per Series C Preferred Unit. In the event that
on or prior to March 31, 2000 (i) the General Partner's senior unsecured debt
shall have an unconditional, published Standard & Poor's rating of at least
"BBB" and (ii) neither Moody's nor any other rating agency with offices located
in at least five (5) cities in the United States shall have in effect an
unconditional, published rating of the General Partner's senior unsecured debt
which is lower than its rating for such senior unsecured debt as of the date
hereof, then beginning on the date on which each of such foregoing conditions
are met, the rate per annum shall be 8.50% of the original Capital Contribution
per Series C Preferred Unit, in which case the designation of the Series C
Preferred Units will change accordingly to reflect such new distribution rate;
provided, that, if (y) either Moody's or any other rating agency with offices
located in at least five (5) cities in the United States shall have in effect on
March 31, 2000 an unconditional, published rating of the General Partner's
senior unsecured debt which is lower than its rating of such senior unsecured
debt as of the date hereof or (z) a Standard & Poor's rating of at least "BBB"
shall no longer be in effect on March 31, 2000, then the revised rate herein
provided shall be void ab initio and the General Partner shall pay on March 31,
2000, in addition to the distribution due to the holders of the Series C
Preferred Units, the difference between (1) the dividend that would have accrued
at the original rate of 8.625% per annum during the current and any prior
quarterly distribution period and (2) the distribution that actually accrued
during such distribution periods at the voided rate of 8.50% per annum. Promptly
after April 1, 2000 the parties hereto shall execute, acknowledge and deliver or
cause to be executed acknowledged and delivered all instruments and documents as
may be reasonably necessary or desirable to memorialize the revised distribution
rate. Such
<PAGE>

distributions shall be cumulative, shall accrue from the original date of
issuance and will be payable (i) quarterly in arrears, on March 1, June 1,
September 1 and December 1 of each year commencing on December 1, 1999 and,
(ii), in the event of (A) an exchange of Series C Preferred Units into Series C
Preferred Shares, or (B) a redemption of Series C Preferred Units, on the
exchange date or redemption date, as applicable (each a "Preferred Unit
Distribution Payment Date"). The amount of the distribution payable for any
period will be computed on the basis of a 360-day year of twelve 30-day months
and for any period shorter than a full quarterly period for which distributions
are computed, the amount of the distribution payable will be computed on the
basis of the actual number of days elapsed in such period. If any date on which
distributions are to be made on the Series C Preferred Units is not a Business
Day (as defined herein), then payment of the distribution to be made on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date. Distributions on the Series C Preferred Units
will be made to the holders of record of the Series C Preferred Units on the
relevant record dates to be fixed by the Partnership acting through the General
Partner, which record dates shall in no event exceed fifteen (15) Business Days
prior to the relevant Preferred Unit Distribution Payment Date (the "Preferred
Unit Partnership Record Date").

      The term "Business Day" shall mean each day other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulations or executive order to close.

      (b) Distributions Cumulative. Distributions on the Series C Preferred
Units will accrue whether or not the terms and provisions of any agreement of
the Partnership, including any agreement relating to its indebtedness, at any
time prohibit the current payment of distributions, whether or not the
Partnership has earnings, whether or not there are funds legally available for
the payment of such distributions and whether or not such distributions are
authorized. Accrued but unpaid distributions on the Series C Preferred Units
will accumulate as of the Preferred Unit Distribution Payment Date on which they
first become payable. Distributions on account of arrears for any past
distribution periods may be declared and paid at any time, without reference to
a regular Preferred Unit Distribution Payment Date to holders of record of the
Series C Preferred Units on the record date fixed by the Partnership acting
through the General Partner, which date shall not exceed fifteen (15) Business
Days prior to the payment date. Accumulated and unpaid distributions will not
bear interest.

      (c) Priority as to Distributions. (i) So long as any Series C Preferred
Units are outstanding, no distribution of cash or other property shall be
authorized, declared, paid or set apart for payment on or with respect to any
class or series of Partnership Interests of the Partnership ranking junior as to
the payment of distributions or rights upon a voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership to the Series C
Preferred Units (collectively, "Junior Units"), nor shall any cash or other
property be set aside for or applied to the purchase, redemption or other
acquisition for consideration of any Series C Preferred Units, any Parity
Preferred Units or any Junior Units, unless, in each case, all
<PAGE>

distributions accumulated on all Series C Preferred Units and all classes and
series of outstanding Parity Preferred Units have been paid in full. The
foregoing sentence will not prohibit (a) distributions payable solely in Junior
Units, (b) the conversion of Junior Units or Parity Preferred Units into
Partnership Units ranking junior to the Series C Preferred Units as to
distributions and upon liquidation, winding-up or dissolution or (c) the
redemption of Partnership Interests corresponding to any Series C Preferred
Shares (as hereinafter defined), Parity Preferred Shares (as such term is
defined in the Declaration of Trust of the General Partner, as supplemented (the
"Charter")), or Junior Shares (as such term is defined in the Charter) to be
purchased by the General Partner pursuant to Article 3 of the Charter to
preserve the General Partner's status as a real estate investment trust,
provided that such redemption shall be upon the same terms as the corresponding
purchase pursuant to Article 3 of the Charter.

            (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series C Preferred Units, all distributions authorized and
declared on the Series C Preferred Units and all classes or series of
outstanding Parity Preferred Units shall be authorized and declared so that the
amount of distributions authorized and declared per Series C Preferred Unit and
such other classes or series of Parity Preferred Units shall in all cases bear
to each other the same ratio that accrued distributions per Series C Preferred
Unit and such other classes or series of Parity Preferred Units (which shall not
include any accumulation in respect of unpaid distributions for prior
distribution periods if such class or series of Parity Preferred Units do not
have cumulative distribution rights) bear to each other.

      (d) No Further Rights. Holders of Series C Preferred Units shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

      Section 4. Liquidation Proceeds. (a) Upon voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, distributions on the
Series C Preferred Units shall be made in accordance with Section 13.2 of the
Partnership Agreement.

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the
Series C Preferred Units at the respective addresses of such holders as the same
shall appear on the transfer records of the Partnership.

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series C Preferred
Units will have no right or claim to any of the remaining assets of the
Partnership.

      (d) Consolidation, Merger or Certain Other Transactions. The voluntary
sale,
<PAGE>

conveyance, lease, exchange or transfer (for cash, shares of stock, securities
or other consideration) of all or substantially all of the property or assets of
the General Partner to, or the consolidation or merger or other business
combination of the Partnership with or into, any corporation, trust,
partnership, limited liability company or other entity (or of any corporation,
trust, partnership, limited liability company or other entity with or into the
Partnership) shall not be deemed to constitute a liquidation, dissolution or
winding-up of the Partnership.

      Section 5. Optional Redemption. (a) Right of Optional Redemption. The
Series C Preferred Units may not be redeemed prior to the fifth (5th)
anniversary of the issuance date. On or after such date, the Partnership shall
have the right to redeem the Series C Preferred Units, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to the Capital Account balance of the holders of Series C Preferred Units (the
"Redemption Price"); provided, however, that no redemption pursuant to this
Section 5 will be permitted if the Redemption Price does not equal or exceed the
original Capital Contribution of such holder plus the cumulative Priority
Return, whether or not declared, to the redemption date to the extent not
previously distributed or distributed pursuant to Section 3(a). If fewer than
all of the outstanding Series C Preferred Units are to be redeemed, the Series C
Preferred Units to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional units).

      (b) Limitation on Redemption. The Partnership may not redeem fewer than
all of the outstanding Series C Preferred Units unless all accumulated and
unpaid distributions have been paid on all Series C Preferred Units for all
quarterly distribution periods terminating on or prior to the date of
redemption.

      (c) Procedures for Redemption. (i) Notice of redemption will be (A) faxed,
and (B) mailed by the Partnership, by certified mail, postage prepaid, not less
than thirty (30) nor more than sixty (60) days prior to the redemption date,
addressed to the respective holders of record of the Series C Preferred Units at
their respective addresses as they appear on the records of the Partnership. No
failure to give or defect in such notice shall affect the validity of the
proceedings for the redemption of any Series C Preferred Units except as to the
holder to whom such notice was defective or not given. In addition to any
information required by law, each such notice shall state: (1) the redemption
date, (2) the Redemption Price, (3) the aggregate number of Series C Preferred
Units to be redeemed and if fewer than all of the outstanding Series C Preferred
Units are to be redeemed, the number of Series C Preferred Units to be redeemed
held by such holder, which number shall equal such holder's pro rata share
(based on the percentage of the aggregate number of outstanding Series C
Preferred Units the total number of Series C Preferred Units held by such holder
represents) of the aggregate number of Series C Preferred Units to be redeemed,
(4) the place or places where such Series C Preferred Units are to be
surrendered for payment of the Redemption Price, (5) that distributions on the
Series C Preferred Units to be redeemed will cease to accumulate on such
redemption date and (6) that payment of the Redemption Price will be made upon
presentation and surrender of such Series C Preferred Units.

            (ii) If the Partnership gives a notice of redemption in respect of
Series C
<PAGE>

Preferred Units (which notice will be irrevocable) then, by 12:00 noon, New York
City time, on the redemption date, the Partnership will deposit irrevocably in
trust for the benefit of the Series C Preferred Units being redeemed funds
sufficient to pay the applicable Redemption Price and will give irrevocable
instructions and authority to pay such Redemption Price to the holders of the
Series C Preferred Units upon surrender of the Series C Preferred Units by such
holders at the place designated in the notice of redemption. If the Series C
Preferred Units are evidenced by a certificate and if fewer than all Series C
Preferred Units evidenced by any certificate are being redeemed, a new
certificate shall be issued upon surrender of the certificate evidencing all
Series C Preferred Units, evidencing the unredeemed Series C Preferred Units
without cost to the holder thereof. On and after the date of redemption,
distributions will cease to accumulate on the Series C Preferred Units or
portions thereof called for redemption, unless the Partnership defaults in the
payment thereof. If any date fixed for redemption of Series C Preferred Units is
not a Business Day, then payment of the Redemption Price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
is improperly withheld or refused and not paid by the Partnership, distributions
on such Series C Preferred Units will continue to accumulate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
applicable Redemption Price.

      Section 6. Voting Rights. (a) General. Holders of the Series C Preferred
Units will not have any voting rights or right to consent to any matter
requiring the consent or approval of the Limited Partners, except as set forth
in the Partnership Agreement and except as set forth below.

      (b) Certain Voting Rights. So long as any Series C Preferred Units remain
outstanding, the Partnership shall not, without the affirmative vote of the
holders of at least two-thirds of the Series C Preferred Units outstanding at
the time (i) authorize or create, or increase the authorized or issued amount
of, any class or series of Partnership Interests senior to the Series C
Preferred Units with respect to payment of distributions or rights upon
liquidation, dissolution or winding-up of the Partnership or reclassify any
Partnership Interests of the Partnership into any such senior Partnership
Interests, or create, authorize or issue any obligations or security convertible
into or evidencing the right to purchase any such senior Partnership Interests,
(ii) authorize or create, or increase the authorized or issued amount of any
Parity Preferred Units or reclassify, any Partnership Interest into any such
Partnership Interest or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such Partnership
Interests but only to the extent such Parity Preferred Units are issued to an
Affiliate of the Partnership, other than the General Partner to the extent the
issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates of the
Partnership (or to Affiliates purchasing the preferred stock of the same series
on the same terms as non-affiliated purchasers) or (iii) either (A) consolidate,
merge into or with, or convey, transfer or lease all or substantially all of its
assets to, any
<PAGE>

corporation or other entity or (B) amend, alter or repeal the provisions of the
Partnership Agreement, including without limitation this Section, whether by
merger, consolidation or otherwise, in each case in a manner that would
materially and adversely affect the powers, special rights, preferences,
privileges or voting power of the Series C Preferred Units or the holders
thereof; provided, however, that with respect to the occurrence of a merger,
consolidation or a sale or lease of all or substantially all of the
Partnership's assets as an entirety, so long as (1) the Partnership is the
surviving entity and the Series C Preferred Units remain outstanding with the
terms thereof unchanged, or (2) the resulting, surviving or transferee entity is
a partnership, limited liability company or other pass-through entity organized
under the laws of any state and substitutes the Series C Preferred Units for
other interests in such entity having substantially the same terms and rights as
the Series C Preferred Units, including with respect to distributions, voting
rights and rights upon liquidation, dissolution or winding-up of the
Partnership, then the occurrence of any such event shall not be deemed to
materially and adversely affect such rights, privileges or voting powers of the
holders of the Series C Preferred Units and no vote of the Series C Preferred
Units shall be required in such case; and provided further that any increase in
the amount of Partnership Interests or the creation or issuance of any other
class or series of Partnership Interests, in each case ranking (y) junior to the
Series C Preferred Units with respect to payment of distributions or the
distribution of assets upon liquidation, dissolution or winding-up of the
Partnership, or (z) on a parity with the Series C Preferred Units with respect
to payment of distributions and the distribution of assets upon liquidation,
dissolution or winding-up of the Partnership to the extent such Partnership
Interests are not issued to an Affiliate, other than the General Partner to the
extent the issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates, shall not be
deemed to materially and adversely affect such rights, preferences, privileges
or voting powers and no vote of the Series C Preferred Units shall be required
in such case.

      In addition to the foregoing, the Partnership will not (x) enter into any
contract, mortgage, loan or other agreement that prohibits or restricts, or has
the effect of prohibiting or restricting, the ability of a holder of Series C
Preferred Units to exercise its rights set forth herein to effect an exchange or
redemption pursuant to Section 8, except with the written consent of such
holder; or (y) amend, alter, or repeal or waive Section 3.1, 11.3(d) or 7.5(a)
of the Partnership Agreement without the affirmative vote of at least a majority
of the Series C Preferred Units outstanding at the time.

      (c) No General Partner Voting Rights. Notwithstanding anything to the
contrary in this Section 6, in no event shall the General Partner or any of its
Affiliates have any voting, consent or approval rights in respect of any Series
C Preferred Units it or they may hold, and any percentage or portion of
outstanding Series C Preferred Units that may be required hereunder for any
vote, consent or approval of holders thereof shall be determined as if all
Series C Preferred Units then held by the General Partner or any of its
Affiliates were not outstanding.

      Section 7. Transfer Restrictions. The Series C Preferred Units shall be
subject to the provisions of Article XI of the Partnership Agreement, provided,
however, that (i) notwithstanding the provisions of such Article XI, the holders
of the Series C Preferred Units
<PAGE>

shall have the absolute right to transfer their units so long as such transfers
(1) do not result in more than five (5) Partners in the aggregate holding the
Series C Preferred Units (within the meaning of Section 1.7704-1 (h)(1)(ii) of
the U.S. Treasury Regulations (including by reason of Section 1.7704-1 (h)(3) or
any successor provision of law)) and (2) do not violate Section 11.3(e) of
Article XI, (ii) the General Partner shall act reasonably in exercising its
discretion pursuant to the provisions of Section 11.4(a)(ii) to transferees of
Series C Preferred Units, (iii) the provisions of Clause B of Section 11.3(d)
shall not be applicable to holders of Series C Preferred Units if at the time of
such transfer, the Partnership already has 100 Partners; (iv) if only a portion
of the Series C Preferred Units shall be transferred, the transferee of such
transferred Series C Preferred Units shall, subject to the provisions of Section
11.4, be substituted as a Limited Partner in place of the transferring holders
only as to the Series C Preferred Units so transferred; and (v) the provisions
of Sections 11.6(c) and 11.6(d) shall not be applicable to any transfer of
Series C Preferred Units; and provided further that "transfer" when used in
Article XI shall not be deemed to include any exchange pursuant to Section 8
below. Notwithstanding anything in this Agreement to the contrary, the Series C
Preferred Units shall be freely transferable to LLC.

      Section 8. Exchange Rights. (a) Right to Exchange. (i) Series C Preferred
Units will be exchangeable in whole or in part at anytime on or after the tenth
(10th) anniversary of the date of issuance, at the option of the holders of more
than 50% of all outstanding Series C Units, for authorized but previously
unissued shares of 8.625% Series C Cumulative Redeemable Preferred Shares of the
General Partner (the "Series C Preferred Shares") at an exchange rate of one
Series C Preferred Share for one Series C Preferred Unit, subject to adjustment
as described below (the "Exchange Price"), provided that the Series C Preferred
Units will become exchangeable at any time, in whole or in part, at the option
of the holders of more than 50% of all outstanding Series C Units, for Series C
Preferred Shares if (y) at any time full distributions shall not have been
timely made on any Series C Preferred Unit with respect to six (6) prior
quarterly distribution periods, whether or not consecutive; provided, however,
that a distribution in respect of Series C Preferred Units shall be considered
timely made if made within two (2) Business Days after the applicable Preferred
Unit Distribution Payment Date if at the time of such late payment there shall
not be any prior quarterly distribution periods in respect of which fall
distributions were not timely made or (z) upon receipt by a holder or holders of
Series C Preferred Units of (1) a notice from the General Partner that the
General Partner or a Subsidiary of the General Partner has become aware of facts
that will or likely will cause the Partnership to become a PTP, (2) an opinion
rendered by an outside nationally recognized independent counsel familiar with
such matters addressed to a holder or holders of Series C Preferred Units, that
the Partnership is or likely is, or upon the occurrence of a defined event in
the immediate future will be or likely will be, a PTP. In addition, the Series C
Preferred Units may be exchanged for Series C Preferred Shares, in whole or in
part, at the option of any holder prior to the tenth (10th) anniversary of the
issuance date and after the third (3rd) anniversary thereof if such holder of a
Series C Preferred Units shall deliver to the General Partner either (i) a
private letter ruling addressed to such holder of Series C Preferred Units or
(ii) an opinion of independent counsel reasonably acceptable to the General
Partner based on the enactment of temporary or final Treasury Regulations or the
publication of a Revenue Ruling, in either case to the effect that an exchange
of the Series C Preferred Units at such earlier time would not cause the Series
C
<PAGE>

Preferred Units to be considered "stock and securities" within the meaning of
Section 351(e) of the Code for purposes of determining whether the holder of
such Series C Preferred Units is an "investment company" under Section 721(b) of
the Code if an exchange is permitted at such earlier date. Furthermore, the
Series C Preferred Units, if a holder thereof so determines, may be exchanged in
whole or in part for Series C Preferred Shares if (1) such holder concludes
based on results or projected results that there exists (in the reasonable
judgment of such holder) an imminent and substantial risk that such holder's
interest in the Partnership represents or will represent more than 18.0% of the
total profits of or capital interests in the Partnership for a taxable year, (2)
such holder delivers to the General Partner an opinion of nationally recognized
independent counsel, reasonably acceptable to the General Partner to the effect
that there is a substantial risk that its interest in the Partnership does not
or will not satisfy the 18.0% limit and (3) the General Partner agrees with the
conclusions referred to in clauses (1) and (2) of this sentence, such agreement
not to be unreasonably withheld.

            (ii) Notwithstanding anything to the contrary set forth in Section
8(a)(i) hereof, if an Exchange Notice (as defined herein) has been delivered to
the General Partner, then the General Partner may, at its option, elect to
redeem or cause the Partnership to redeem all or a portion of the outstanding
Series C Preferred Units for cash in an amount equal to the original Capital
Contribution per Series C Preferred Unit and all accrued and unpaid
distributions thereon to the date of redemption. The General Partner may
exercise its option to redeem the Series C Preferred Units for cash pursuant to
this Section 8(a)(ii) hereof by giving each holder of record of Series C
Preferred Units notice of its election to redeem for cash, within five (5)
Business Days after receipt of the Exchange Notice, by (y) fax, and (z)
registered mail, postage paid, at the address of each holder as it may appear on
the records of the Partnership stating (A) the redemption date, which shall be
no later than sixty (60) days following the receipt of the Exchange Notice, (B)
the redemption price, (C) the place or places where the Series C Preferred Units
are to be surrendered for payment of the redemption price, (D) that
distributions on the Series C Preferred Units will cease to accrue on such
redemption date; (E) that payment of the redemption price will be made upon
presentation and surrender of the Series C Preferred Units and (F) the aggregate
number of Series C Preferred Units to be redeemed, and if fewer than all of the
outstanding Series C Preferred Units are to be redeemed, the number of Series C
Preferred Units to be redeemed held by such holder, which number shall equal
such holder's pro-rata share (based on the percentage of the aggregate number of
outstanding Series C Preferred Units the total number of Series C Preferred
Units held by such holder represents) of the aggregate number of Series C
Preferred Units being redeemed.

            (iii) In the event an exchange of all or a portion of Series C
Preferred Units pursuant to Section 8(a)(i) hereof would violate the provisions
on ownership limitation of the General Partner set forth in Article 3 of the
Charter with respect to the Series C Preferred Shares, the General Partner shall
give written notice thereof to each holder of record of Series C Preferred
Units, within five (5) Business Days following receipt of the Exchange Notice,
by (y) fax, and (z) registered mail, postage prepaid, at the address of each
such holder set forth in the records of the Partnership. In such event, each
holder of Series C Preferred Units shall be entitled to exchange, pursuant to
the provision of Section 8(b) a number of Series C Preferred Units
<PAGE>

which would comply with the provisions on the ownership limitation of the
General Partner set forth in such Article 3 of the Charter and any Series C
Preferred Units not so exchanged (the "Excess Units") shall be redeemed by the
Partnership for cash in an amount equal to the original Capital Contribution per
Excess Unit, plus any accrued and unpaid distributions thereon, whether or not
declared, to the date of redemption. The written notice of the General Partner
shall state (A) the number of Excess Units held by such holder, (B) the
redemption price of the Excess Units, (C) the date on which such Excess Units
shall be redeemed, which date shall be no later than sixty (60) days following
the receipt of the Exchange Notice, (D) the place or places where such Excess
Units are to be surrendered for payment of the Redemption Price, (E) that
distributions on the Excess Units will cease to accrue on such redemption date,
and (F) that payment of the redemption price will be made upon presentation and
surrender of such Excess Units. In the event an exchange would result in Excess
Units, as a condition to such exchange, each holder of such units agrees to
provide representations and covenants reasonably requested by the General
Partner relating to (1) the widely held nature of the interests in such holder,
sufficient to assure the General Partner that the holder's ownership of stock of
the General Partner (without regard to the limits described above) will not
cause any individual to Beneficially Own in excess of the Ownership Limit (all
as defined in the General Partner's Charter); and (2) to the extent such holder
can so represent and covenant without obtaining information from its owners, the
holder's ownership of tenants of the Partnership and its affiliates.

      To the extent the General Partner would not be able to pay the cash set
forth above in exchange for the Series C Excess Units, and to the extent
consistent with the Charter, the General Partner agrees that it will grant to
the holders of the Series C Preferred Units exceptions to the Beneficial
Ownership Limit and Constructive Ownership Limit set forth in the Charter
sufficient to allow such holders to exchange all of their Series C Preferred
Units for Series C Preferred Shares, provided such holders furnish to the
General Partner representations acceptable to the General Partner in its sole
and absolute discretion which assure the General Partner that such exceptions
will not jeopardize the General Partner's tax status as a REIT for purposes of
federal and applicable state law.

      Notwithstanding any provision of this Agreement to the contrary, no Series
C Limited Partner shall be entitled to effect an exchange of Series C Preferred
Units for Series C Preferred Shares to the extent that ownership or right to
acquire such shares would cause the Partner or any other Person or, in the
opinion of counsel selected by the General Partner, may cause the Partner or any
other Person, to violate the restrictions on ownership and transfer of Series C
Preferred Shares set forth in the Charter. To the extent any such attempted
exchange for Series C Preferred Shares would be in violation of the previous
sentence, it shall be void ab initio and such Series C Limited Partner shall not
acquire any rights or economic interest in the Series C Preferred Shares
otherwise issuable upon such exchange.

            (iv) The redemption of Series C Preferred Units described in Section
8(a)(ii) and (iii) shall be subject to the provisions of Section 5(c)(ii);
provided, however, that the term "Redemption Price" in such section shall be
read to mean the original Capital Contribution per
<PAGE>

Series C Preferred Unit being redeemed plus all accrued and unpaid distributions
to the redemption date.

      (b) Procedure for Exchange. (i) Any exchange shall be exercised pursuant
to a notice of exchange (the "Exchange Notice") delivered to the General Partner
by the holder who is exercising such exchange right, by (A) fax and (B) by
certified mail postage prepaid. The exchange of Series C Preferred Units, or a
specified portion thereof, may be effected after the fifth (5th) Business Day
following receipt by the General Partner of the Exchange Notice by delivering
certificates, if any, representing such Series C Preferred Units to be exchanged
together with, if applicable, written notice of exchange and a proper assignment
of such Series C Preferred Units to the office of the General Partner maintained
for such purpose. Currently, such office is Two Center Plaza, Suite 200, Boston,
Massachusetts 02108. Each exchange will be deemed to have been effected
immediately prior to the close of business on the date on which such Series C
Preferred Units to be exchanged (together with all required documentation) shall
have been surrendered and notice shall have been received by the General Partner
as aforesaid and the Exchange Price shall have been paid. Any Series C Preferred
Shares issued pursuant to this Section 8 shall be delivered as shares which are
duly authorized, validly issued, fully paid and nonassessable, free of pledge,
lien, encumbrance or restriction other than those provided in the Charter, the
Bylaws of the General Partner, the Securities Act of 1933 and relevant state
securities or blue sky laws.

            (ii) In the event of an exchange of Series C Preferred Units for
Series C Preferred Shares, an amount equal to the accrued and unpaid
distributions, whether or not declared, to the date of exchange on any Series C
Preferred Units tendered for exchange shall (A) accrue on the Series C Preferred
Shares into which such Series C Preferred Units are exchanged, and (B) continue
to accrue on such Series C Preferred Units, which shall remain outstanding
following such exchange, with the General Partner as the holder of such Series C
Preferred Units. Notwithstanding anything to the contrary set forth herein, in
no event shall a holder of a Series C Preferred Unit that was validly exchanged
into Series C Preferred Shares pursuant to this section (other than the General
Partner now holding such Series C Preferred Unit), receive a cash distribution
out of Available Cash of the Partnership, if such holder, after exchange, is
entitled to receive a distribution out of Available Cash with respect to the
Series C Preferred Shares for which such Series C Preferred Unit was exchanged
or redeemed.

      Further, for purposes of the foregoing, in the event of an exchange of
Series C Preferred Units for Series C Preferred Shares, if the accrued and
unpaid distributions per Series C Preferred Unit is not the same for all Series
C Preferred Units, the accrued and unpaid distributions per Series C Preferred
Unit for all Series C Preferred Units shall be equal to the greatest amount of
such accrued and unpaid distributions per Series C Preferred Unit on any such
unit.

            (iii) Fractional shares of Series C Preferred Shares are not to be
issued upon exchange but, in lieu thereof, the General Partner will pay a cash
adjustment based upon the fair market value of the Series C Preferred Shares on
the day prior to the exchange date as determined in good faith by the Board of
Directors of the General Partner.
<PAGE>

      (c) Adjustment of Exchange Price. (i) The Exchange Price is subject to
adjustment upon certain events, including (a) subdivisions, combinations and
reclassifications of the Series C Preferred Shares and (b) distributions to all
holders of Series C Preferred Shares of evidences of indebtedness of the General
Partner or assets (including securities but excluding dividends and
distributions paid out of equity applicable to Series C Preferred Shares).

                  (ii) In case the General Partner shall be a party to any
transaction (including, without limitation, a merger, consolidation, statutory
share exchange, tender offer for all or substantially all of the General
Partner's capital stock or sale of all or substantially all of the General
Partner's assets), in each case as a result of which the Series C Preferred
Shares will be converted into the right to receive shares of capital stock,
other securities or other property (including cash or any combination thereof),
each Series C Preferred Unit will thereafter be exchangeable into the kind and
amount of shares of capital stock and other securities and property receivable
(including cash or any combination thereof) upon the consummation of such
transaction by a holder of that number of Series C Preferred Shares or fraction
thereof into which one Series C Preferred Unit was exchangeable immediately
prior to such transaction. The General Partner may not become a party to any
such transaction, whether or not any Series C Preferred Shares are then
outstanding if the terms thereof are inconsistent with the foregoing. In
addition, so long as a Series C Limited Partner or any of its permitted
successors or assigns hold any Series C Preferred Units, as the case may be, the
General Partner shall not, without the affirmative vote of the holders of at
least two-thirds in the aggregate of the Series C Preferred Units outstanding at
the time and the holders of at least two-thirds of the Series C Preferred Shares
outstanding at the time: (a) designate or create, or increase the authorized or
issued amount of, any class or series of shares ranking senior to the Series C
Preferred Shares with respect to the payment of distributions or rights upon
liquidation, dissolution or winding-up or reclassify any authorized shares of
the General Partner into any such shares, or create, authorize or issue any
obligations or securities convertible into or evidencing the right to purchase
any such shares; (b) designate or create, or increase the authorized or issued
amount of, any Parity Preferred Shares or reclassify any authorized shares of
the General Partner into any such shares, or create, authorize or issue any
obligations or security convertible into or evidencing the right to purchase any
such shares, but only to the extent that such Parity Preferred Shares are issued
to an Affiliate of the General Partner (unless the Affiliate is purchasing on
the same terms in the same series as a non- affiliate); (c) amend, alter or
repeal the provisions of the Charter or bylaws of the General Partner, whether
by merger, consolidation or otherwise, that would materially and adversely
affect the powers, special rights, preferences, privileges or voting power of
the Series C Preferred Shares or the holders thereof; provided, however, that
any increase in the amount of authorized Preferred Shares or the creation or
issuance of any other series or class of Preferred Shares, or any increase in
the amount of authorized shares of each class or series, in each case ranking
either (1) junior to the Series C Preferred Shares with respect to the payment
of distributions and the distribution of assets upon liquidation, dissolution or
winding-up, or (2) on a parity with the Series C Preferred Shares with respect
to the payment of distributions and the distribution of assets upon liquidation,
dissolution or winding-up to the extent such Preferred Shares are not issued to
an Affiliate of the Company, shall not be deemed to materially and
<PAGE>

adversely affect such rights, preferences, privileges or voting powers.

      Section 9. No Conversion Rights. (a) The holders of the Series C Preferred
Units shall not have any rights to convert such Partnership Units into any other
class of Partnership Interests or any interest in the Partnership; (b) The
Series C Preferred Units shall not be subject to the provisions of Section
4.2(e) of the Partnership Agreement.

      Section 10. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of the Series C Preferred Units.

      Section 11. Admission of Limited Partner; Exhibits to Partnership
Agreement. In accordance with Section 12.2(b), Contributor is hereby admitted as
an Additional Limited Partner. In order to duly reflect the issuance of Series C
Preferred Units provided for herein, the Partnership Agreement will be amended
by deleting Exhibit A attached thereto and substituting a new Exhibit A attached
hereto therefor within 10 business days hereof.

      Section 12. Reaffirmation. Except as modified herein, all terms and
conditions of the Partnership Agreement shall remain in full force and effect,
which terms and conditions the General Partner hereby ratifies and affirms.

      Section 13. Amendments to Partnership Agreement. The following shall be
incorporated into Section 14.1(c) of the Partnership Agreement:

            "Notwithstanding any other provisions of this Agreement, this
      Agreement shall not be amended, and no action may be taken by the General
      Partner, without the Consent of each Partner adversely affected if such
      amendment or action would (i) convert a Limited Partner's interest in the
      Partnership into a general partner's interest (except as the result of the
      General Partner acquiring such interest), (ii) modify the limited
      liability of a Limited Partner, (iii) alter rights of the Partner to
      receive distributions pursuant to Article 5 or Section 13.2, or the
      allocations specified in Article 6 (except as permitted pursuant to
      Section 4.2(a)), (iv) cause the termination of the Partnership prior to
      the time set forth in Sections 2.5 or 13.1, (v) alter the redemption or
      exchange rights as set forth in Sections 5 and 8 hereof, respectively, or
      (vi) amend this Section 12. Further, no amendment may alter the
      restrictions on the General Partner's authority set forth elsewhere in
      this Section 12 without the Consent specified in such section. Any such
      amendment or action consented to by any Limited Partner shall be effective
      as to that Limited Partner, notwithstanding the absence of such consent by
      any other Limited Partner."
<PAGE>

      IN WITNESS WHEREOF, this Amendment has been executed as of the date first
above written.

                                2,600,000 SHARES

             8.625% SERIES C CUMULATIVE REDEEMABLE PREFERRED SHARES

      Cabot Industrial Trust, a Maryland real estate investment trust (the
"Company"), hereby certifies to the State Department of Assessments and Taxation
of Maryland (the "Department") that:

            FIRST: Under a power contained in Article 2, Section 1 of the
Amended and Restated Declaration of Trust of the Company, filed with, and
accepted for record by, the State Department of Assessments and Taxation of
Maryland (the "SDAT") on January 26, 1998, as supplemented by Articles
Supplementary filed with, and accepted for record by, the SDAT on July 10, 1998
and on April 29, 1999 (the "Charter"), the Board of Trustees of the Company, as
required by Section 8-203(b) of the Corporations and Associations Article of the
Annotated Code of Maryland, has unanimously adopted resolutions classifying and
designating 2,600,000 unissued shares of beneficial interest (the "Shares") as
8.625% Series C Cumulative Redeemable Preferred Shares, with the following
preferences, conversion and other rights, voting powers, restrictions,
limitations as to dividends and other distributions, qualifications and terms
and conditions of redemption, and other terms and conditions, which upon any
restatement of the Charter shall be made part of Article 2 of the Charter, with
any necessary or appropriate changes to the enumeration and lettering thereof:

                  8.625% SERIES C CUMULATIVE REDEEMABLE SHARES

      SECTION 1. Designation and Number. A series of preferred shares,
designated the "8.625% Series C Cumulative Redeemable Preferred Shares" (the
"Series C Preferred Shares") is hereby established. The number of shares of
Series C Preferred Shares shall be 2,600,000.

      SECTION 2. Rank. The Series C Preferred Shares shall, with respect to
distributions and rights upon voluntary or involuntary liquidation, winding-up
or dissolution of the Company, rank senior to all classes or series of common
Shares and to all classes or series of equity securities of the Company now or
hereafter authorized, issued or outstanding, other than any class or series of
equity securities of the Company expressly designated as ranking on a parity
with or senior to the Series C Preferred Shares as to distributions and rights
upon voluntary or involuntary liquidation, winding-up or dissolution of the
Company. For purposes of these Articles Supplementary, the term "Parity
Preferred Shares" shall be used to refer to any class or series of equity
securities of the Company now or hereafter authorized, issued or outstanding
expressly designated by the Company to rank on a parity with Series C Preferred
Shares with respect to distributions and rights upon voluntary or involuntary
liquidation, winding-up or dissolution of the Company, including specifically
the Series B Cumulative Redeemable Preferred Shares. The term "equity
securities" does not include debt securities, which will rank senior to the
Series C Preferred Shares prior to conversion.

      SECTION 3. Distributions.

      (a) Payment of Distributions. Subject to the rights of holders of Parity
Preferred Shares and holders of equity securities ranking senior to the Series C
Preferred Shares as to payment of distributions, holders of Series C Preferred
Shares will be entitled to receive, when, as and if declared by the Board of
Trustees of the Company, out of funds legally available for the payment of
distributions, cumulative preferential cash distributions at the rate per annum
of 8.625", of the $25 liquidation preference per Series C Preferred Share. In
the event that on or prior to March 31, 2000 (i) the Company's senior unsecured
debt shall have an unconditional, published, Standard & Poor's rating of at
least "BBB" and (ii) neither Moody's nor any other rating agency with offices
located in at least five (5) cities in the United States shall have in effect an
unconditional, published, rating of the Company's senior unsecured
<PAGE>

debt which is lower than its rating for such senior unsecured debt as of the
date hereof, then beginning on the date on which each of such foregoing
conditions are met, the rate per annum shall be 8.50% of the $25 liquidation
preference per Series C Preferred Share, in which case the designation of the
Series C Preferred Shares will change accordingly to reflect such new
distribution rate; provided, that, if(y) either Moody's or any other rating
agency with offices located in at least five (5) cities in the United States
shall have in effect on March 31, 2000 an unconditional published rating of the
Company's senior unsecured debt which is lower than its rating of such senior
unsecured debt as of the date hereof or (z) a Standard & Poor's rating of at
least "BBB" shall no longer be in effect on March 31, 2000, then the revised
rate herein provided shall be void ab initio and the Company shall pay on March
31, 2000, in addition to the dividend then due to the holders of the Series C
Preferred Shares, the difference between (1) the dividend that would have
accrued at the original rate of 8.625% per annum during the current and any
prior quarterly distribution period and (2) the dividend that actually accrued
during such distribution periods at the voided rate of 8.50% per annum. Promptly
after April 1, 2000 the parties hereto shall execute, acknowledge and deliver or
cause to be executed acknowledged and delivered all instruments and documents as
may be reasonably necessary or desirable to memorialize the revised distribution
rate. Such distributions shall be cumulative, shall accrue from the original
date of issuance and will be payable (i) quarterly in arrears, on March 1, June
1, September 1 and December 1 of each year commencing on the first of such dates
to occur after the original date of issuance and, (ii) in the event of a
redemption, on the redemption date (each a "Preferred Shares Distribution
Payment Date"). The amount of the distribution payable for any period will be
computed on the basis of a 360-day year of twelve 30-day months and for any
period shorter than a full quarterly period for which distributions are
computed, the amount of the distribution payable will be computed on the basis
of the actual number of days elapsed in such period. If any date on which
distributions are to be made on the Series C Preferred Shares is not a Business
Day (as defined herein), then payment of the distribution to be made on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date. Distributions on the Series C Preferred Shares
will be made to the holders of record of the Series C Preferred Shares on the
relevant record dates, which, unless otherwise provided by the Company with
respect to any distribution, will be fifteen (15) Business Days prior to the
relevant Preferred Shares Distribution Payment Date (each a "Distribution Record
Date"). Notwithstanding anything to the contrary set forth herein, each Series C
Preferred Share shall also continue to accrue all accrued and unpaid
distributions up to the exchange date on any Series C Preferred Unit (as defined
in the Second Amended and Restated Agreement of Limited Partnership of Cabot
Industrial Properties, L.P., dated as of February 4, 1998 (the "Partnership
Agreement"), as amended through the date hereof) validly exchanged into such
Series C Preferred Share in accordance with the provisions of such Partnership
Agreement.

      The term "Business Day" shall mean each day, other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulation or executive order to close.

      (b) Limitation on Distributions. No distributions on the Series C
Preferred Shares shall be declared or paid or set apart for payment by the
Company at such time as the terms and provisions of any agreement of the
Company, including any agreement relating to its indebtedness, prohibits such
declaration, payment or setting apart for payment or provides that such
declaration, payment or setting apart for payment would constitute a breach
thereof or a default thereunder, or if such declaration, payment or setting
apart for payment shall be restricted or prohibited by law.

      (c) Distributions Cumulative. Notwithstanding the foregoing, distributions
on the Series C Preferred Shares will accrue whether or not the terms and
provisions set forth in Section 3(b) hereof at any time prohibit the current
payment of distributions, whether or not the Company has earnings, whether or
not there are funds legally available for the payment of such distributions and
whether or not such distributions are authorized or declared. Accrued but unpaid
distributions on the Series C Preferred Shares will accumulate as of the
Preferred Shares Distribution Payment Date on which they first become payable.
Accumulated and unpaid distributions will not bear interest.

      (d) Priority as to Distributions. (i) So long as any Series C Preferred
Shares are outstanding, no
<PAGE>

distribution of cash or other property shall be authorized, declared, paid or
set apart for payment on or with respect to any class or series of common Shares
or any class or series of other Shares of the Company ranking junior as to the
payment of distributions or rights upon voluntary or involuntary dissolution,
liquidation or winding up of the Company to the Series C Preferred Shares (such
common Shares or other junior Shares, including, without limitation Series A
Junior Participating Preferred Shares authorized pursuant to Articles
Supplementary filed with the Department on July 10, 1998, collectively, "Junior
Shares"), nor shall any cash or other property be set aside for or applied to
the purchase, redemption or other acquisition for consideration of any Series C
Preferred Shares, any Parity Preferred Shares or any Junior Shares, unless, in
each case, all distributions accumulated on all Series C Preferred Shares and
all classes and series of outstanding Parity Preferred Shares have been paid in
full. The foregoing sentence will not prohibit (i) distributions payable solely
in Shares of the Company ranking junior to the Series C Preferred Shares as to
distributions and upon liquidation, winding-up or dissolution, (ii) the
conversion of Junior Shares or Parity Preferred Shares into Shares of the
Company ranking junior to the Series C Preferred Shares as to distributions and
upon liquidation, winding up or dissolution, and (iii) purchase by the Company
of such Series C Preferred Shares. Parity Preferred Shares or Junior Shares
pursuant to Article 3 of the Charter to the extent required to preserve the
Company's status as a real estate investment trust.

            (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series C Preferred Shares, all distributions authorized and
declared on the Series C Preferred Shares and all classes or series of
outstanding Parity Preferred Shares shall be authorized and declared so that the
amount of distributions authorized and declared per share of Series C Preferred
Shares and such other classes or series of Parity Preferred Shares shall in all
cases bear to each other the same ratio that accrued distributions per share on
the Series C Preferred Shares and such other classes or series of Parity
Preferred Shares (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Shares do not have cumulative distribution rights) bear to each other.

      (e) No Further Rights. Holders of Series C Preferred Shares shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

      SECTION 4. Liquidation Preference.

      (a) Payment of Liquidating Distributions. Subject to the rights of holders
of Parity Preferred Shares and subject to equity securities ranking senior to
the Series C Preferred Shares with respect to rights upon any voluntary or
involuntary liquidation, dissolution or winding-up of the Company, the holders
of Series C Preferred Shares shall be entitled to receive out of the assets of
the Company legally available for distribution or the proceeds thereof, after
payment or provision for debts and other liabilities of the Company, but before
any payment or distributions of the assets shall be made to holders of common
Shares or any other class or series of shares of the Company that ranks junior
to the Series C Preferred Shares as to rights upon liquidation, dissolution or
winding-up of the Company, an amount equal to the sum of (i) a liquidation
preference of $25 per Series C Preferred Share, and (ii) an amount equal to any
accumulated and unpaid distributions thereon, whether or not declared, to the
date of payment. In the event that, upon such voluntary or involuntary
liquidation, dissolution or winding-up, there are insufficient assets to permit
full payment of liquidating distributions to the holders of Series C Preferred
Shares and any Parity Preferred Shares, all payments of liquidating
distributions on the Series C Preferred Shares and such Parity Preferred Shares
shall be made so that the payments on the Series C Preferred Shares and such
Parity Preferred Shares shall in all cases bear to each other the same ratio
that the respective rights of the Series C Preferred Shares and such other
Parity Preferred Shares (which shall not include any accumulation in respect of
unpaid distributions for prior distribution periods if such Parity Preferred
Shares do not have cumulative distribution rights) upon liquidation, dissolution
or winding-up of the Company bear to each other.

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Company, stating the payment date
or dates when, and the place or places where, the amounts distributable in such
circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the
Series C Preferred Shares at the respective addresses of such holders as the
same shall appear on the share transfer records of the Company.
<PAGE>

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series C Preferred
Shares will have no right or claim to any of the remaining assets of the
Company.

      (d) Consolidation, Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all of the property
or assets of the Company to, or the consolidation or merger or other business
combination of the Company with or into any corporation, trust or other entity
(or of any corporation, trust or other entity with or into the Company) shall
not be deemed to constitute a liquidation, dissolution or winding-up of the
Company.

      SECTION 5. Optional Redemption.

      (a) Right of Optional Redemption. The Series C Preferred Shares may not be
redeemed prior to September 3, 2004. On or after such date, the Company shall
have the right to redeem the Series C Preferred Shares, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to $25 per share of Series C Preferred Shares plus accumulated and unpaid
distributions, whether or not declared, to the date of redemption. If fewer than
all of the outstanding Series C Preferred Shares are to be redeemed, the Series
C Preferred Shares to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional shares).

      (b) Limitation on Redemption. The Company may not redeem fewer than all of
the outstanding shares of Series C Preferred Shares unless all accumulated and
unpaid distributions have been paid on all outstanding Series C Preferred Shares
for all quarterly distribution periods terminating on or prior to the date of
redemption.

      (c) Procedures for Redemption. (i) Notice of redemption will be (i) faxed,
and (ii) mailed by the Company, postage prepaid, not less than thirty (30) nor
more than sixty (60) days prior to the redemption date, addressed to the
respective holders of record of the Series C Preferred Shares to be redeemed at
their respective addresses as they appear on the transfer records of the
Company. No failure to give or defect in such notice shall affect the validity
of the proceedings for the redemption of any Series C Preferred Shares except as
to the holder to whom such notice was defective or not given. In addition to any
information required by law or by the applicable rules of any exchange upon
which the Series C Preferred Shares may be listed or admitted to trading, each
such notice shall state: (i) the redemption date, (ii) the redemption price,
(iii) the number of Series C Preferred Shares to be redeemed, (iv) the place or
places where such Series C Preferred Shares are to be surrendered for payment of
the redemption price, (v) that distributions on the Series C Preferred Shares to
be redeemed will cease to accumulate on such redemption date and (vi) that
payment of the redemption price and any accumulated and unpaid distributions
will be made upon presentation and surrender of such Series C Preferred Shares.
If fewer than all of the Series C Preferred Shares held by any holder are to be
redeemed, the notice mailed to such holder shall also specify the number of
Series C Preferred Shares held by such holder to be redeemed.

            (ii) If the Company gives a notice of redemption in respect of
Series C Preferred Shares (which notice will be irrevocable) then, by 12:00
noon, New York City time, on the redemption date, the Company will deposit
irrevocably in trust for the benefit of the holders of the Series C Preferred
Shares being redeemed, funds sufficient to pay the applicable redemption price,
plus any accumulated and unpaid distributions, whether or not declared, if any,
on such shares to the date fixed for redemption, without interest, and will give
irrevocable instructions and authority to pay such redemption price and any
accumulated and unpaid distributions, whether or not declared, if any, on such
shares to the holders of the Series C Preferred Shares upon surrender of the
certificates for the Series C Preferred Shares by such holders at the place
designated in the notice of redemption. If fewer than all Series C Preferred
Shares evidenced by any certificate are being redeemed, a new certificate shall
be issued upon surrender of the certificate evidencing all Series C Preferred
Shares, evidencing the unredeemed Series C Preferred Shares without cost to the
holder thereof. On and after the date of redemption, distributions will cease to
accumulate on the Series C Preferred Shares or portions thereof called for
redemption, unless the Company defaults
<PAGE>

in the payment thereof. If any date fixed for redemption of Series C Preferred
Shares is not a Business Day, then payment of the redemption price payable on
such date will be made on the next succeeding day that is a Business Day (and
without any interest or other payment in respect of any such delay) except that,
if such Business Day falls in the next calendar year, such payment will be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date fixed for redemption. If payment of the
redemption price or any accumulated or unpaid distributions in respect of the
Series C Preferred Shares is improperly withheld or refused and not paid by the
Company, distributions on such Series C Preferred Shares will continue to
accumulate from the original redemption date to the date of payment, in which
case the actual payment date will be considered the date fixed for redemption
for purposes of calculating the applicable redemption price and any accumulated
and unpaid distributions.

      (e) Status of Redeemed Shares. Any Series C Preferred Shares that shall at
any time have been redeemed shall after such redemption, have the status of
authorized but unissued Shares, without designation as to class or series until
such shares are once more designated as part of a particular class or series by
the Board.

      SECTION 6. Voting Rights.

      (a) General. Holders of the Series C Preferred Shares will not have any
voting rights, except as set forth below.

      (b) Right to Elect Trustees. (i) If at any time full distributions shall
not have been timely made on any Series C Preferred Shares with respect to any
six (6) prior quarterly distribution periods, whether or not consecutive (a
"Preferred Distribution Default"), the holders of such Series C Preferred
Shares, voting together as a single class with the holders of each class or
series of Parity Preferred Shares upon which like voting rights have been
conferred and are exercisable, will have the right to elect two additional
Trustees to serve on the Company's Board (the "Preferred Shares Trustees") at a
special meeting called by the holders of record of at least 10% of the
outstanding Series C Preferred Shares or any such class or series of Parity
Preferred Shares or at the next annual meeting of Shareholders, and at each
subsequent annual meeting of Shareholders or special meeting for the election of
Trustees held in place thereof, until all such distributions in arrears and
distributions for the current quarterly period on the Series C Preferred Shares
and each such class or series of Parity Preferred Shares have been paid in full.

            (ii) At any time when such voting rights shall have vested, a proper
officer of the Company shall call or cause to be called, upon written request of
holders of record of at least 10% of the outstanding Series C Preferred Shares,
a special meeting of the holders of Series C Preferred Shares and all the series
of Parity Preferred Shares upon which like voting rights have been conferred and
are exercisable (collectively, the "Parity Securities") by mailing or causing to
be mailed to such holders a notice of such special meeting to be held not less
than ten and not more than 45 days after the date such notice is given. The
record date for determining holders of the Parity Securities entitled to notice
of and to vote at such special meeting will be the close of business on the
third Business Day preceding the day on which such notice is mailed. At any such
special meeting, all of the holders of the Parity Securities, by plurality vote,
voting together as a single class without regard to series will be entitled to
elect two Trustees on the basis of one vote per $25.00 of liquidation preference
to which such Parity Securities are entitled by their terms (excluding amounts
in respect of accumulated and unpaid dividends) and not cumulatively. The holder
or holders of one-third of the Parity Securities then outstanding, present in
person or by proxy, will constitute a quorum for the election of the Preferred
Shares Trustees except as otherwise provided by law. Notice of all meetings at
which holders of the Series C Preferred Shares shall be entitled to vote will be
given to such holders at their addresses as they appear in the transfer records.
At any such meeting or adjournment thereof in the absence of a quorum, subject
to the provisions of any applicable law, a majority of the holders of the Parity
Securities present in person or by proxy shall have the power to adjourn the
meeting for the election of the Preferred Shares Trustees, without notice other
than an announcement at the meeting, until a quorum is present. If a Preferred
Distribution Default shall terminate after the notice of a special meeting has
been given but before such special meeting has been held, the Company shall, as
soon as practicable after such termination, mail or cause to be mailed notice of
such termination to holders of the Series C Preferred Shares that would have
been entitled to vote at such special meeting.
<PAGE>

            (iii) If and when all accumulated distributions and the
distributions for the current distribution period on the Series C Preferred
Shares shall have been paid in full or a sum sufficient for such payment is
irrevocably deposited in trust for payment, the holders of the Series C
Preferred Shares shall be divested of the voting rights set forth in this
Section 6(b) herein (subject to revesting in the event of each and every
Preferred Distribution Default) and, if all distributions in arrears and the
distributions for the current distribution period have been paid in full or set
aside for payment in full on all other classes or series of Parity Preferred
Shares upon which like voting rights have been conferred and are exercisable,
the term and office of each Preferred Shares Trustee so elected shall terminate.
Any Preferred Shares Trustee may be removed at any time with or without cause by
the vote of, and shall not be removed otherwise than by the vote of, the holders
of record of a majority of the outstanding Parity Securities when they have the
voting rights set forth in this Section 6(b). So long as a Preferred
Distribution Default shall continue, any vacancy in the office of a Preferred
Shares Trustee may be filled by written consent of the Preferred Shares Trustee
remaining in office, or if none remains in office, by a vote of the holders of
record of a majority of the outstanding Parity Securities when they have the
voting rights set forth in this Section 6(b). The Preferred Shares Trustees
shall each be entitled to one vote per trustee on any matter.

      (c) Certain Voting Rights. So long as any Series C Preferred Shares or
Series C Preferred Units remain outstanding, the Company shall not, without the
affirmative vote of the holders of at least two-thirds of the Series C Preferred
Shares and Series C Preferred Units outstanding at the time (together, as
applicable, voting as a single class) (collectively, the "Voting Securities")
(i) designate or create, or increase the authorized or issued amount of, any
class or series of shares ranking senior to the Series C Preferred Shares with
respect to payment of distributions or rights upon liquidation, dissolution or
winding-up of the Company or reclassify any authorized shares of the Company
into any such shares, or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such shares, (ii)
designate or create, or increase the authorized or issued amount of, any Parity
Preferred Shares or reclassify any authorized shares of the Company into any
such shares, or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such shares, but only
to the extent such Parity Preferred Shares are issued to an affiliate of the
Company (unless the affiliate is purchasing on the same terms as a
non-affiliate), or (iii) either (A) consolidate, merge into or with, or convey,
transfer or lease its assets substantially as an entirety, to any corporation or
other entity, or (B) amend, alter or repeal the provisions of the Company's
Charter (including these Articles Supplementary) or By-laws, whether by merger,
consolidation or otherwise, in each case that would materially and adversely
affect the powers, special rights, preferences, privileges or voting power of
the Series C Preferred Shares or the holders thereof; provided, however, that
with respect to the occurrence of a merger, consolidation or a sale or lease of
all or substantially all of the Company's assets as an entirety, so long as (a)
the Company is the surviving entity and the Series C Preferred Shares remain
outstanding (or the Series C Preferred Units remain exchangeable for Series C
Preferred Shares) with the terms thereof unchanged, or (b) the resulting,
surviving or transferee entity is a corporation organized under the laws of any
state and substitutes the Series C Preferred Shares for other preferred Shares
having substantially the same terms and same rights as the Series C Preferred
Shares, including with respect to distributions, voting rights and rights upon
liquidation, dissolution or winding-up of the Company, then the occurrence of
any such event shall not be deemed to materially and adversely affect such
rights, privileges or voting powers of the holders of the Series C Preferred
Shares and no vote of the Series C Preferred Shares shall be required; and
provided further that any increase in the amount of authorized Shares or the
creation or issuance of any other class or series of Shares, or any increase in
an amount of authorized shares of each class or series, in each case ranking
either (a) junior to the Series C Preferred Shares with respect to payment of
distributions and the distribution of assets upon liquidation, dissolution or
winding-up of the Company, or (b) on a parity with the Series C Preferred Shares
with respect to payment of distributions or the distribution of assets upon
liquidation, dissolution or winding-up of the Company to the extent such Shares
are not issued to an affiliate of the Company, shall not be deemed to materially
and adversely affect such rights, preferences, privileges or voting powers and
no vote of the Voting Securities shall be required.

      SECTION 7. Transfer Restrictions. The Series C Preferred Shares shall be
subject to the provisions of Article 3 of the Charter; provided, however, in no
event shall the Ownership Limit with respect to the Series C Preferred Shares
(as defined in the Charter) be decreased pursuant to Section 10 of Article 3 of
the Charter or otherwise (other than a decrease as a result of a retroactive
change in existing law that would require a decrease to retain real estate
investment trust status under the Internal Revenue Code of 1986, as amended).
<PAGE>

      SECTION 8. No Conversion Rights. The holders of the Series C Preferred
Shares shall not have any rights to convert such shares into shares of any other
class or series of Shares or into any other securities of, or interest in, the
Company.

      SECTION 9. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of Series C Preferred Shares.

      SECTION 10. No Preemptive Rights. No holder of the Series C Preferred
Shares of the Company shall, as such holder, have any preemptive rights to
purchase or subscribe for additional Shares of the Company or any other security
of the Company which it may issue or sell.

            FOURTH: The Series C Preferred Shares have been classified and
designated by the Board under the authority contained in the Charter.

            FIFTH: These Articles Supplementary have been approved by the Board
in the manner and by the vote required by law.

            SIXTH: The undersigned President of the Company acknowledges these
Articles Supplementary to be the corporate act of the Company and, as to all
matters or facts required to be verified under oath, the undersigned President
acknowledges that to the best of his knowledge, information and belief, these
matters and facts are true in all material respects and that this statement is
made under the penalties for perjury.

      IN WITNESS WHEREOF, the Company has caused these Articles Supplementary to
be executed under seal in its name and on its behalf by its President and
attested to by its Secretary on this __ day of September, 1999.

                                 THIRD AMENDMENT
                                       TO
                           SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                        CABOT INDUSTRIAL PROPERTIES, L.P.

      THIS THIRD AMENDMENT TO SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED
PARTNERSHIP (this "Amendment") dated as of September 27, 1999, is entered into
by CABOT INDUSTRIAL TRUST, a Maryland real estate investment trust, as general
partner (the "General Partner") of CABOT INDUSTRIAL PROPERTIES, L.P. (the
"Partnership"), for itself and on behalf of the limited partners of the
Partnership, and J.P. MORGAN MOSAIC FUND II, LLC, a Delaware limited liability
company ("Contributor").

      WHEREAS, Section 4.2(a) of the Second Amended and Restated Agreement of
Limited Partnership of the Partnership (the "Partnership Agreement") authorizes
the General Partner to cause the Partnership to issue additional Partnership
Units in one or more classes or series, with such designations, preferences and
relative, participating, optional or other special rights, powers and duties as
shall be determined by the General Partner, subject to the provisions of such
section; and

      WHEREAS, pursuant to the authority granted to the General Partner pursuant
to Sections 4.2(a) and 14.1(b) of the Partnership Agreement, the General Partner
desires to amend the Partnership Agreement (i) to establish a new class of
Partnership Units, the Series D Preferred Units (as hereinafter defined), and to
set forth the designations, rights, powers, preferences and ditties of such
Series D Preferred Units, (ii) to issue the Series D Preferred Units to
Contributor and admit Contributor as an Additional Limited Partner and (iii) to
make certain other changes to the Partnership Agreement.

NOW, THEREFORE, in consideration of good and valuable consideration, the receipt
and sufficiency of which hereby are acknowledged, the General Partner hereby
amends the Partnership Agreement as follows:

      Section 1. Definitions. For purposes of this Amendment, the term "Parity
Preferred Units" shall be used to refer to any class or series of Partnership
Interests of the Partnership now or hereafter authorized, issued or outstanding
expressly designated by the Partnership to rank on a parity with Series D
Preferred Units with respect to distributions and rights upon voluntary or
involuntary liquidation, winding-up or dissolution of the Partnership. The term
"Priority Return" shall mean, an amount equal to 8.375% per annum, determined on
the basis of a 360 day year of twelve 30 day months, cumulative to the extent
not distributed for any given distribution period pursuant to Section 5.1 of the
Partnership Agreement, of the stated value of S50 per Series D Preferred Unit,
commencing on the date of issuance of such Series D Preferred Unit. The term
"Subsidiary" shall mean with respect to any person, any corporation,
partnership, limited liability company, joint venture or other entity of which a
majority of(i) voting power of the voting equity securities or (ii) the
outstanding equity interests, is owned, directly or indirectly, by such person.
The term "PTP" shall mean a "publicly traded partnership" within the meaning of
Section 7704 of the Code. Capitalized terms used herein and
<PAGE>

not otherwise defined herein shall have the meanings ascribed to them in the
Partnership Agreement.

      Section 2. Designation and Number. A series of Partnership Units in the
Partnership designated as the "8.375% Series D Cumulative Redeemable Preferred
Units" (the "Series D Preferred Units") is hereby established. The number of
Series D Preferred Units shall be 200,000.

      Section 3. Distributions. (a) Payment of Distributions. Subject to the
rights of holders of Parity Preferred Units as to the payment of distributions,
pursuant to Section 5.1 of the Partnership Agreement, holders of Series D
Preferred Units shall be entitled to receive, when, as and if declared by the
Partnership acting through the General Partner, out of Available Cash,
cumulative preferential cash distributions at the rate per annum of 8.375% of
the original Capital Contribution per Series D Preferred Unit. Such
distributions shall be cumulative, shall accrue from the original date of
issuance and will be payable (i) quarterly in arrears, on March 25, June 25,
September 25 and December 25 of each year commencing on December 25, 1999 and,
(ii), in the event of (A) an exchange of Series D Preferred Units into Series D
Preferred Shares, or (B) a redemption of Series D Preferred Units, on the
exchange date or redemption date, as applicable (each a "Preferred Unit
Distribution Payment Date"). The amount of the distribution payable for any
period will be computed on the basis of a 360-day year of twelve 30-day months
and for any period shorter than a full quarterly period for which distributions
are computed, the amount of the distribution payable will be computed on the
basis of the actual number of days elapsed in such period. If any date on which
distributions are to be made on the Series D Preferred Units is not a Business
Day (as defined herein), then payment of the distribution to be made on such
date will be made on the next succeeding day that is a Business Day (and without
any interest or other payment in respect of any such delay) except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date. Distributions on the Series D Preferred Units
will be made to the holders of record of the Series D Preferred Units on the
relevant record dates to be fixed by the Partnership acting through the General
Partner, which record dates shall in no event exceed fifteen (15) Business Days
prior to the relevant Preferred Unit Distribution Payment Date (the "Preferred
Unit Partnership Record Date").

      The term "Business Day" shall mean each day other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulations or executive order to close.

            (b) Distributions Cumulative. Distributions on the Series D
Preferred Units will accrue whether or not the terms and provisions of any
agreement of the Partnership, including any agreement relating to its
indebtedness, at any time prohibit the current payment of distributions, whether
or not the Partnership has earnings, whether or not there are funds legally
available for the payment of such distributions and whether or not such
distributions are authorized. Accrued but unpaid distributions on the Series D
Preferred Units will accumulate as of the Preferred Unit Distribution Payment
Date on which they first become payable. Distributions on account of arrears for
any past distribution periods may be declared and paid at any time, without
reference to a regular Preferred Unit Distribution Payment Date to holders of
record of the Series D Preferred Units on the record date fixed by the
Partnership acting through
<PAGE>

the General Partner, which date shall not exceed fifteen (15) Business Days
prior to the payment date. Accumulated and unpaid distributions will not bear
interest.

            (c) Priority as to Distributions. (i) So long as any Series D
Preferred Units are outstanding, no distribution of cash or other property shall
be authorized, declared, paid or set apart for payment on or with respect to any
class or series of Partnership Interests of the Partnership ranking junior as to
the payment of distributions or rights upon a voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership to the Series D
Preferred Units (collectively, "Junior Units"), nor shall any cash or other
property be set aside for or applied to the purchase, redemption or other
acquisition for consideration of any Series D Preferred Units, any Parity
Preferred Units or any Junior Units, unless, in each case, all distributions
accumulated on all Series D Preferred Units and all classes and series of
outstanding Parity Preferred Units have been paid in full. The foregoing
sentence will not prohibit (a) distributions payable solely in Junior Units, (b)
the conversion of Junior Units or Parity Preferred Units into Partnership Units
ranking junior to the Series D Preferred Units as to

            distributions and upon liquidation, winding-up or dissolution or (c)
the redemption of Partnership Interests corresponding to any Series D Preferred
Shares (as hereinafter defined), Parity Preferred Shares (as such term is
defined in the Declaration of Trust of the General Partner, as supplemented (the
"Charter")), or Junior Shares (as such term is defined in the Charter) to be
purchased by the General Partner pursuant to Article 3 of the Charter to
preserve the General Partner's status as a real estate investment trust,
provided that such redemption shall be upon the same terms as the corresponding
purchase pursuant to Article 3 of the Charter.

      (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series D Preferred Units, all distributions authorized and
declared on the Series D Preferred Units and all classes or series of
outstanding Parity Preferred Units shall be authorized and declared so that the
amount of distributions authorized and declared per Series D Preferred Unit and
such other classes or series of Parity Preferred Units shall in all cases bear
to each other the same ratio that accrued distributions per Series D Preferred
Unit and such other classes or series of Parity Preferred Units (which shall not
include any accumulation in respect of unpaid distributions for prior
distribution periods if such class or series of Parity Preferred Units do not
have cumulative distribution rights) bear to each other.

            (d) No Further Rights. Holders of Series D Preferred Units shall not
be entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

      Section 4. Liquidation Proceeds. (a) Upon voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, distributions on the
Series D Preferred Units shall be made in accordance with Section 13.2 of the
Partnership Agreement.

            (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the
Series D Preferred Units at the respective addresses of such holders as the same
shall appear on


                                       3
<PAGE>

the transfer records of the Partnership.

            (c) No Further Rights. After payment of the full amount of the
liquidating distributions to which they are entitled, the holders of Series D
Preferred Units will have no right or claim to any of the remaining assets of
the Partnership.

            (d) Consolidation, Merger or Certain Other Transactions. The
voluntary sale, conveyance, lease, exchange or transfer (for cash, shares of
stock, securities or other consideration) of all or substantially all of the
property or assets of the General Partner to, or the consolidation or merger or
other business combination of the Partnership with or into, any corporation,
trust, partnership, limited liability company or other entity (or of any
corporation, trust, partnership, limited liability company or other entity with
or into the Partnership) shall not be deemed to constitute a liquidation,
dissolution or winding-up of the Partnership.

      Section 5. Optional Redemption. (a) Right of Optional Redemption. The
Series D Preferred Units may not be redeemed prior to the fifth (5th)
anniversary of the issuance date. On or after such date, the Partnership shall
have the right to redeem the Series D Preferred Units, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to the Capital Account balance of the holders of Series D Preferred Units (the
"Redemption Price") provided, however, that no redemption pursuant to this
Section 5 will be permitted if the Redemption Price does not equal or exceed the
original Capital Contribution of such holder plus the cumulative Priority
Return, whether or not declared, to the redemption date to the extent not
previously distributed or distributed pursuant to Section 3(a). If fewer than
all of the outstanding Series D Preferred Units are to be redeemed, the Series D
Preferred Units to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional units).

            (b) Limitation on Redemption. The Partnership may not redeem fewer
than all of the outstanding Series D Preferred Units unless all accumulated and
unpaid distributions have been paid on all Series D Preferred Units for all
quarterly distribution periods terminating on or prior to the date of
redemption.

            (c) Procedures for Redemption. (i) Notice of redemption will be (A)
faxed, and (B) mailed by the Partnership, by certified mail, postage prepaid,
not less than thirty (30) nor more than sixty (60) days prior to the redemption
date, addressed to the respective holders of record of the Series D Preferred
Units at their respective addresses as they appear on the records of the
Partnership. No failure to give or defect in such notice shall affect the
validity of the proceedings for the redemption of any Series D Preferred Units
except as to the holder to whom such notice was defective or not given. In
addition to any information required by law, each such notice shall state: (1)
the redemption date, (2) the Redemption Price, (3) the aggregate number of
Series D Preferred Units to be redeemed and if fewer than all of the outstanding
Series D Preferred Units are to be redeemed, the number of Series D Preferred
Units to be redeemed held by such holder, which number shall equal such holder's
pro rata share (based on the percentage of the aggregate number of outstanding
Series D Preferred Units the total number of Series D Preferred Units held by
such holder represents) of the aggregate number of Series D Preferred Units to
be redeemed, (4) the place or places where such Series D Preferred Units are to
be surrendered for payment of the Redemption Price, (5) that distributions on
the Series D Preferred Units to be redeemed will cease to accumulate on such
redemption date and (6) that payment of the Redemption Price will be made upon
presentation and surrender of such Series D


                                       4
<PAGE>

Preferred Units.

      (ii) If the Partnership gives a notice of redemption in respect of Series
D Preferred Units (which notice will be irrevocable) then, by 12:00 noon, New
York City time, on the redemption date, the Partnership will deposit irrevocably
in trust for the benefit of the Series D Preferred Units being redeemed funds
sufficient to pay the applicable Redemption Price and will give irrevocable
instructions and authority to pay such Redemption Price to the holders of the
Series D Preferred Units upon surrender of the Series D Preferred Units by such
holders at the place designated in the notice of redemption. If the Series D
Preferred Units are evidenced by a certificate and if fewer than all Series D
Preferred Units evidenced by any certificate are being redeemed, a new
certificate shall be issued upon surrender of the certificate evidencing all
Series D Preferred Units, evidencing the unredeemed Series D Preferred Units
without cost to the holder thereof. On and after the date of redemption,
distributions will cease to accumulate on the Series D Preferred Units or
portions thereof called for redemption, unless the Partnership defaults in the
payment thereof. If any date fixed for redemption of Series D Preferred Units is
not a Business Day, then payment of the Redemption Price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
is improperly withheld or refused and not paid by the Partnership, distributions
on such Series D Preferred Units will continue to accumulate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
applicable Redemption Price.

      Section 6. Voting Rights. (a) General. Holders of the Series D Preferred
Units will not have any voting rights or right to consent to any matter
requiring the consent or approval of the Limited Partners, except as set forth
in the Partnership Agreement and except as set forth below. In the event of a
conflict between the terms of this Section 6 and any other terms of this
Amendment, the terms of this Section 6 shall control.

            (b) Certain Voting Rights. So long as any Series D Preferred Units
remain outstanding, the Partnership shall not, without the affirmative vote of
the holders of at least two-thirds of the Series D Preferred Units outstanding
at the time (i) authorize or create, or increase the authorized or issued amount
of, any class or series of Partnership Interests senior to the Series D
Preferred Units with respect to payment of distributions or rights upon
liquidation, dissolution or winding-up of the Partnership or reclassify any
Partnership Interests of the Partnership into any such senior Partnership
Interests, or create, authorize or issue any obligations or security convertible
into or evidencing the right to purchase any such senior Partnership Interests,
(ii) authorize or create, or increase the authorized or issued amount of any
Parity Preferred Units or reclassify any Partnership Interest into any such
Partnership Interest or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such Partnership
Interests but only to the extent such Parity Preferred Units are issued to an
Affiliate of the Partnership, other than the General Partner to the extent the
issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates of the
Partnership (or to Affiliates purchasing the preferred stock on the same terms
as non-affiliated purchasers) or (iii) either (A) consolidate, merge into or
with,


                                       5
<PAGE>

or convey, transfer or lease all or substantially all of its assets to, any
corporation or other entity or (B) amend, alter or repeal the provisions of the
Partnership Agreement whether by merger, consolidation or otherwise, that would
materially and adversely affect the powers, special rights, preferences,
privileges or voting power of the Series D Preferred Units or the holders
thereof, provided, however, that with respect to the occurrence of a merger,
consolidation or a sale or lease of all or substantially all of the
Partnership's assets as an entirety, so long as (1) the Partnership is the
surviving entity and the Series D Preferred Units remain outstanding with the
terms thereof unchanged, or (2) the resulting, surviving or transferee entity is
a partnership, limited liability company or other pass-through entity organized
under the laws of any state and substitutes the Series D Preferred Units for
other interests in such entity having substantially the same terms and rights as
the Series D Preferred Units, including with respect to distributions, voting
rights and rights upon liquidation, dissolution or winding-up of the
Partnership, then the occurrence of any such event shall not be deemed to
materially and adversely affect such rights, privileges or voting powers of the
holders of the Series D Preferred Units and no vote of the Series D Preferred
Units shall be required in such case; and provided further that any increase in
the amount of Partnership Interests or the creation or issuance of any other
class or series of Partnership Interests, in each case ranking (y) junior to the
Series D Preferred Units with respect to payment of distributions or the
distribution of assets upon liquidation, dissolution or winding-up of the
Partnership, or (z) on a parity with the Series D Preferred Units with respect
to payment of distributions and the distribution of assets upon liquidation,
dissolution or winding-up of the Partnership to the extent such Partnership
Interests are not issued to an Affiliate, other than the General Partner to the
extent the issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates, shall not be
deemed to materially and adversely affect such rights, preferences, privileges
or voting powers and no vote of the Series D Preferred Units shall be required
in such case.

      Section 7. Transfer Restrictions. The Series D Preferred Units shall be
subject to the provisions of Article XI of the Partnership Agreement, provided,
however, that (i) the General Partner shall act reasonably in exercising its
discretion pursuant to the provisions of Section 11.4(a)(ii) to transferees of
Series D Preferred Units, (ii) the provisions of Clause B of Section 11.3(d)
shall not be applicable to holders of Series D Preferred Units if at the time of
such transfer, the Partnership already has 100 Partners; (iii) if only a portion
of the Series D Preferred Units shall be transferred, the transferee of such
transferred Series D Preferred Units shall, subject to the provisions of Section
11.4, be substituted as a Limited Partner in place of the transferring holders
only as to the Series D Preferred Units so transferred; and (iv) the provisions
of Sections 11.6(c) and 11.6(d) shall not be applicable to any transfer of
Series D Preferred Units; and provided further that "transfer" when used in
Article XI shall not be deemed to include any exchange pursuant to Section 8
below.

      Section 8. Exchange Rights. (a) Right to Exchange. (i) Series D Preferred
Units will be exchangeable in whole or in part at anytime on or after the tenth
(10th) anniversary of the date of issuance, at the option of the holders
thereof, for authorized but previously unissued shares of 8.375% Series D
Cumulative Redeemable Preferred Shares of the General Partner (the "Series D
Preferred Shares") at an exchange rate of one Series D Preferred Share for one
Series D Preferred Unit, subject to adjustment as described below (the "Exchange
Price"), provided that the Series D Preferred Units will become exchangeable at
any time, in whole or in part, at the


                                       6
<PAGE>

option of the holders of Series D Units, for Series D Preferred Shares if (y) at
any time full distributions shall not have been timely made on any Series D
Preferred Unit with respect to six (6) prior quarterly distribution periods,
whether or not consecutive; provided, however, that a distribution in respect of
Series D Preferred Units shall be considered timely made if made within two (2)
Business Days after the applicable Preferred Unit Distribution Payment Date if
at the time of such late payment there shall not be any prior quarterly
distribution periods in respect of which full distributions were not timely made
or (z) upon receipt by a holder or holders of Series D Preferred Units of (1) a
notice from the General Partner that the General Partner or a Subsidiary of the
General Partner has taken the position that the Partnership is, or upon the
occurrence of a defined event in the immediate future will be, a PTP and (2) an
opinion rendered by an outside nationally recognized independent counsel
familiar with such matters addressed to a holder or holders of Series D
Preferred Units, that the Partnership is or likely is, or upon the occurrence of
a defined event in the immediate future will be or likely will be, a PTP. In
addition, the Series D Preferred Units may be exchanged for Series D Preferred
Shares, in whole or in part, at the option of any holder prior to the tenth
(10th) anniversary of the issuance date and after the third (3rd) anniversary
thereof if such holder of a Series D Preferred Units shall deliver to the
General Partner either (i) a private letter ruling addressed to such holder of
Series D Preferred Units or (ii) an opinion of independent counsel reasonably
acceptable to the General Partner based on the enactment of a statute, temporary
or final Treasury Regulations or the publication of a Revenue Ruling, in either
case to the effect that an exchange of the Series D Preferred Units at such
earlier time would not cause the Series D Preferred Units to be considered
"stock or securities" within the meaning of Section 351(e) of the Code for
purposes of determining whether the holder of such Series D Preferred Units is
an "investment company" under Section 721(b) of the Code if an exchange is
permitted at such earlier date. Furthermore, all the Series D Preferred Units,
held by any holder thereof which is a real estate investment trust within the
meaning of Sections 856 through 859 of the Code for Series D Preferred Shares
may be exchanged in whole but not in part (but only if the exchange may be
accomplished consistently with the ownership limitations set forth under Article
3 of the Charter (taking into account exceptions thereto)) if at any time, (i)
the Partnership reasonably determines that the assets and income of the
Partnership for a taxable year after 1999 would not satisfy the income and
assets tests of Section 856 of the Code for such taxable year if the Partnership
were a real estate investment trust within the meaning of the Code or (ii) any
such holder of Series B Preferred Units shall deliver to the Partnership and the
General Partner an opinion of independent counsel reasonably acceptable to the
General Partner to the effect that, based on the assets and income of the
Partnership for a taxable year after 1999, the Partnership would not satisfy the
income assets tests of Section 856 of the Code for such taxable year if the
Partnership were a real estate investment trust within the meaning of the Code
and that such failure would create a meaningful risk that a holder of the Series
B Preferred Units would fail to maintain qualification as a real estate
investment trust.

      (ii) Notwithstanding anything to the contrary set forth in Section 8(a)(i)
hereof, if an Exchange Notice (as defined herein) has been delivered to the
General Partner, then the General Partner may, at its option, elect to redeem or
cause the Partnership to redeem all or a portion of the outstanding Series D
Preferred Units for cash in an amount equal to the original Capital Contribution
per Series D Preferred Unit and all accrued and unpaid distributions thereon to
the


                                       7
<PAGE>

date of redemption. The General Partner may exercise its option to redeem the
Series D Preferred Units for cash pursuant to this Section 8(a)(ii) hereof by
giving each holder of record of Series D Preferred Units notice of its election
to redeem for cash, within ten (10) Business Days after receipt of the Exchange
Notice, by (y) fax, and (z) registered mail, postage paid, at the address of
each holder as it may appear on the records of the Partnership stating (A) the
redemption date, which shall be no later than sixty (60) days following the
receipt of the Exchange Notice, (B) the redemption price, (D) the place or
places where the Series D Preferred Units are to be surrendered for payment of
the redemption price, (D) that distributions on the Series D Preferred Units
will cease to accrue on such redemption date; (E) that payment of the redemption
price will be made upon presentation and surrender of the Series D Preferred
Units and (F) the aggregate number of Series D Preferred Units to be redeemed,
and if fewer than all of the outstanding Series D Preferred Units are to be
redeemed, the number of Series D Preferred Units to be redeemed held by such
holder, which number shall equal such holder's pro-rata share (based on the
percentage of the aggregate number of outstanding Series D Preferred Units the
total number of Series D Preferred Units held by such holder represents) of the
aggregate number of Series D Preferred Units being redeemed.

      (iii) In the event an exchange of all or a portion of Series D Preferred
Units pursuant to Section 8(a)(i) hereof would violate the provisions on
ownership limitation of the General Partner set forth in Article 3 of the
Charter with respect to the Series D Preferred Shares, the General Partner shall
give written notice thereof to each holder of record of Series D Preferred
Units, within ten (10) Business Days following receipt of the Exchange Notice,
by (y) fax, and (z) registered mail, postage prepaid, at the address of each
such holder set forth in the records of the Partnership. In such event, each
holder of Series D Preferred Units shall be entitled to exchange, pursuant to
the provision of Section 8(b) a number of Series D Preferred Units which would
comply with the provisions on the ownership limitation of the General Partner
set forth in such Article 3 of the Charter and any Series D Preferred Units not
so exchanged (the "Excess Units") shall be redeemed by the Partnership for cash
in an amount equal to the original Capital Contribution per Excess Unit, plus
any accrued and unpaid distributions thereon, whether or not declared, to the
date of redemption. The written notice of the General Partner shall state (A)
the number of Excess Units held by such holder, (B) the redemption price of the
Excess Units, (D) the date on which such Excess Units shall be redeemed, which
date shall be no later than sixty (60) days following the receipt of the
Exchange Notice, (D) the place or places where such Excess Units are to be
surrendered for payment of the Redemption Price, (E) that distributions on the
Excess Units will cease to accrue on such redemption date, and (F) that payment
of the redemption price will be made upon presentation and surrender of such
Excess Units. In the event an exchange would result in Excess Units, as a
condition to such exchange, each holder of such units agrees to provide
representations and covenants reasonably requested by the General Partner
relating to (1) the widely held nature of the interests in such holder,
sufficient to assure the General Partner that the holder's ownership of stock of
the General Partner (without regard to the limits described above) will not
cause any individual to Beneficially Own in excess of the Ownership Limit (all
as defined in the General Partner's Charter); and (2) to the extent such holder
can so represent and covenant without obtaining information from its owners, the
holder's ownership of tenants of the Partnership and its affiliates.


                                       8
<PAGE>

      (iv) The redemption of Series D Preferred Units described in Section
8(a)(ii) and (iii) shall be subject to the provisions of Sections 5(b) and
5(c)(ii); provided, however, that the term "Redemption Price" in such section
shall be read to mean the original Capital Contribution per Series D Preferred
Unit being redeemed plus all accrued and unpaid distributions to the redemption
date.

            (b) Procedure for Exchange. (i) Any exchange pursuant to this
Amendment shall be exercised pursuant to a notice of exchange (the "Exchange
Notice") delivered to the General Partner by the holder who is exercising such
exchange right, by (A) fax and (B) by certified mail postage prepaid. The
exchange of Series D Preferred Units, or a specified portion thereof, may be
effected after the fifth (5th) Business Day following receipt by the General
Partner of the Exchange Notice by delivering certificates, if any, representing
such Series D Preferred Units to be exchanged together with, if applicable,
written notice of exchange and a proper assignment of such Series D Preferred
Units to the office of the General Partner maintained for such purpose.
Currently, such office is Two Center Plaza, Suite 200, Boston, Massachusetts
02108. Each exchange will be deemed to have been effected immediately prior to
the close of business on the date on which such Series D Preferred Units to be
exchanged (together with all required documentation) shall have been surrendered
and notice shall have been received by the General Partner as aforesaid and the
Exchange Price shall have been paid. Any Series D Preferred Shares issued
pursuant to this Section 8 shall be delivered as shares which are duly
authorized, validly issued, fully paid and nonassessable, free of pledge, lien,
encumbrance or restriction other than those provided in the Charter, the Bylaws
of the General Partner, the Securities Act of 1933 and relevant state securities
or blue sky laws.

      (ii) In the event of an exchange of Series D Preferred Units for Series D
Preferred Shares, an amount equal to the accrued and unpaid distributions,
whether or not declared, to the date of exchange on any Series D Preferred Units
tendered for exchange shall (A) accrue on the Series D Preferred Shares into
which such Series D Preferred Units are exchanged, and (B) continue to accrue on
such Series D Preferred Units, which shall remain outstanding following such
exchange, with the General Partner as the holder of such Series D Preferred
Units. Notwithstanding anything to the contrary set forth herein, in no event
shall a holder of a Series D Preferred Unit that was validly exchanged into
Series D Preferred Shares pursuant to this section (other than the General
Partner now holding such Series D Preferred Unit), receive a cash distribution
out of Available Cash of the Partnership, if such holder, after exchange, is
entitled to receive a distribution out of Available Cash with respect to the
Series D Preferred Shares for which such Series D Preferred Unit was exchanged
or redeemed.

            (iii) Fractional shares of Series D Preferred Shares are not to be
issued upon exchange but, in lieu thereof, the General Partner will pay a cash
adjustment based upon the fair market value of the Series D Preferred Shares on
the day prior to the exchange date as determined in good faith by the Board of
Directors of the General Partner.

            (c) Adjustment of Exchange Price. (i) The Exchange Price is subject
to adjustment upon certain events, including (a) subdivisions, combinations and
reclassifications of the Series D Preferred Shares and (b) distributions to all
holders of Series D Preferred Shares of evidences of indebtedness of the General
Partner or assets (including securities but excluding dividends and
distributions paid out of equity applicable to Series D Preferred Shares).

      (ii) In case the General Partner shall be a party to any transaction
(including,


                                       9
<PAGE>

without limitation, a merger, consolidation, statutory share exchange, tender
offer for all or substantially all of the General Partner's capital stock or
sale of all or substantially all of the General Partner's assets), in each case
as a result of which the Series D Preferred Shares will be converted into the
right to receive shares of capital stock, other securities or other property
(including cash or any combination thereof), each Series D Preferred Unit will
thereafter be exchangeable into the kind and amount of shares of capital stock
and other securities and property receivable (including cash or any combination
thereof) upon the consummation of such transaction by a holder of that number of
Series D Preferred Shares or fraction thereof into which one Series D Preferred
Unit was exchangeable immediately prior to such transaction. The General Partner
may not become a party to any such transaction unless the terms thereof are
inconsistent with the foregoing.

      Section 9. No Conversion Rights. (a) The holders of the Series D Preferred
Units shall not have any rights to convert such Partnership Units into any other
class of Partnership Interests or any interest in the Partnership;

      (b) The Series D Preferred Units shall not be subject to the provisions of
Section 4.2(e) of the Partnership Agreement.

      Section 10. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of the Series D Preferred Units.

      Section 11. Admission of Limited Partner; Exhibits to Partnership
Agreement. In accordance with Section 12.2(b), Contributor is hereby admitted as
an Additional Limited Partner. In order to duly reflect the issuance of Series D
Preferred Units provided for herein, the Partnership Agreement will be amended
by deleting Exhibit A attached thereto and substituting Exhibit A attached
hereto therefor.

      Section 12. Reaffirmation. Except as modified herein, all terms and
conditions of the Partnership Agreement shall remain in full force and effect,
which terms and conditions the General Partner hereby ratifies and affirms.

             8.375% SERIES D CUMULATIVE REDEEMABLE PREFERRED SHARES

      Cabot Industrial Trust, a Maryland real estate investment trust (the
"Company"), hereby certifies to the State Department of Assessments and Taxation
of Maryland (the "Department") that:

            FIRST: Under a power contained in Article 2, Section 1 of the

accepted for record by, the State Department of Assessments and Taxation of
Maryland (the "SDAT") on January 26, 1998, as supplemented by Articles
Supplementary filed with, and accepted for record by, the SDAT on July 10, 1998,

Shares, par value $0.01 per share, with the following preferences, conversion
and other rights, voting powers, restrictions, limitations as to dividends and
other distributions, qualifications and terms and conditions of redemption, and

to the enumeration and lettering thereof.

            SECOND:The following is a description of the Shares, including the
preference, conversion and other rights, voting powers, restrictions,
limitations as to dividends, qualifications, and terms and conditions of
redemption thereof:

                  8.375% Series D CUMULATIVE REDEEMABLE SHARES

      SECTION 1. Designation and Number. A series of preferred shares,
designated the "8.375% Series D Cumulative Redeemable Preferred Shares" (the
"Series D Preferred Shares") is hereby established. The number of shares of
Series D Preferred Shares shall be 200,000, par value $0.01 per share.

      SECTION 2. Rank. The Series D Preferred Shares shall, with respect to
distributions and rights upon voluntary or involuntary liquidation, winding-up
or dissolution of the Company, rank senior to all classes or series of common
shares and to all classes or series of equity securities of the Company now or
hereafter authorized, issued or outstanding, other than any class or series of
equity securities of the Company expressly designated as ranking on a parity
with or senior to the Series D Preferred Shares as to distributions and rights
upon voluntary or involuntary liquidation, winding-up or dissolution of the
Company. For purposes of these Articles Supplementary, the term "Parity
Preferred Shares" shall be used to refer to any class or series of equity
securities of the Company now or hereafter authorized, issued or outstanding
expressly designated by the Company to rank on a parity with Series D Preferred
Shares with respect to distributions and rights upon voluntary or involuntary
liquidation, winding-up or dissolution of the Company, including specifically
the Series B Cumulative Redeemable Preferred Shares and Series C Cumulative
Redeemable Preferred Shares. The term "equity securities" does not include debt
securities, which will rank senior to the Series D Preferred Shares prior to
conversion.

      SECTION 3. Distributions.

      (a) Payment of Distributions. Subject to the rights of holders of Parity
Preferred Shares and holders of equity securities ranking senior to the Series D
Preferred Shares as to payment of distributions, holders of Series D Preferred
Shares will be entitled to receive, when, as and if declared by the Board of
Trustees of the Company, out of funds legally available for the payment of
distributions, cumulative preferential cash distributions at the rate per annum
of 8.375% of the $50 liquidation preference per Series D Preferred Share. Such
distributions shall be
<PAGE>

cumulative, shall accrue from the original date of issuance and will be payable
(i) quarterly in arrears, on March 25, June 25, September 25 and December 25 of
each year commencing on the first of such dates to occur after the original date
of issuance and, (ii) in the event of a redemption, on the redemption date (each
a "Preferred Shares Distribution Payment Date"). The amount of the distribution
payable for any period will be computed on the basis of a 360-day year of twelve
30-day months and for any period shorter than a full quarterly period for which
distributions are computed, the amount of the distribution payable will be
computed on the basis of the actual number of days elapsed in such period. If
any date on which distributions are to be made on the Series D Preferred Shares
is not a Business Day (as defined herein), then payment of the distribution to
be made on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay)
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date. Distributions on the
Series D Preferred Shares will be made to the holders of record of the Series D
Preferred Shares on the relevant record dates, which, unless otherwise provided
by the Company with respect to any distribution, will be fifteen (15) Business
Days prior to the relevant Preferred Shares Distribution Payment Date (each a
"Distribution Record Date"). Notwithstanding anything to the contrary set forth
herein, each Series D Preferred Share shall also continue to accrue all accrued
and unpaid distributions up to the exchange date on any Series D Preferred Unit
(as defined in the Second Amended and Restated Agreement of Limited Partnership
of Cabot Industrial Properties, L.P., dated as of February 4, 1998 (the
"Partnership Agreement"), as amended through the date hereof) validly exchanged
into such Series D Preferred Share in accordance with the provisions of such
Partnership Agreement.

      The term "Business Day" shall mean each day, other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulation or executive order to close.

      (b) Limitation on Distributions. No distributions on the Series D
Preferred Shares shall be declared or paid or set apart for payment by the
Company at such time as the terms and provisions of any agreement of the
Company, including any agreement relating to its indebtedness, prohibits such
declaration, payment or setting apart for payment or provides that such
declaration, payment or setting apart for payment would constitute a breach
thereof or a default thereunder, or if such declaration, payment or setting
apart for payment shall be restricted or prohibited by law.

      (c) Distributions Cumulative. Notwithstanding the foregoing, distributions
on the Series D Preferred Shares will accrue whether or not the terms and
provisions set forth in Section 3(b) hereof at any time prohibit the current
payment of distributions, whether or not the Company has earnings, whether or
not there are funds legally available for the payment of such distributions and
whether or not such distributions are authorized or declared. Accrued but unpaid
distributions on the Series D Preferred Shares will accumulate as of the
Preferred Shares Distribution Payment Date on which they first become payable.
Accumulated and unpaid distributions will not bear interest.

      (d) Priority as to Distributions. (i) So long as any Series D Preferred
Shares are outstanding, no distribution of cash or other property shall be
authorized, declared, paid or set apart for payment on or with respect to any
class or series of common shares or any class or series of other Shares of the
Company ranking junior as to the payment of distributions or rights upon
voluntary or involuntary dissolution, liquidation or winding up of the Company
to the Series D Preferred Shares (such common shares or other junior Shares,
including, without limitation Series A Junior Participating Preferred Shares
authorized pursuant to Articles Supplementary filed with the Department on July
10, 1998, collectively, "Junior Shares"), nor shall any cash or other property
be set aside for or applied to the purchase, redemption or other acquisition for
consideration of any Series D Preferred Shares, any Parity Preferred Shares or
any Junior Shares, unless, in each case, all distributions accumulated on all
Series D Preferred Shares and all classes and series of outstanding Parity
Preferred Shares have been paid in full. The foregoing sentence will not
prohibit (i) distributions payable solely in Shares of the Company ranking
junior to the Series D Preferred Shares as to distributions and upon
liquidation, winding-up or dissolution, (ii) the conversion of Junior Shares or
Parity Preferred Shares into Shares of the Company ranking junior to the Series
D Preferred Shares as to distributions and upon liquidation, winding up or
dissolution, and (iii) purchase by the Company of such Series
<PAGE>

D Preferred Shares, Parity Preferred Shares or Junior Shares pursuant to Article
3 of the Charter to the extent required to preserve the Company's status as a
real estate investment trust.

            (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series D Preferred Shares, all distributions authorized and
declared on the Series D Preferred Shares and all classes or series of
outstanding Parity Preferred Shares shall be authorized and declared so that the
amount of distributions authorized and declared per share of Series D Preferred
Shares and such other classes or series of Parity Preferred Shares shall in all
cases bear to each other the same ratio that accrued distributions per share on
the Series D Preferred Shares and such other classes or series of Parity
Preferred Shares (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Shares do not have cumulative distribution rights) bear to each other.

      (e) No Further Rights. Holders of Series D Preferred Shares shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

      SECTION 4. Liquidation Preference.

      (a) Payment of Liquidating Distributions. Subject to the rights of holders
of Parity Preferred Shares and subject to equity securities ranking senior to
the Series D Preferred Shares with respect to rights upon any voluntary or
involuntary liquidation, dissolution or winding-up of the Company, the holders
of Series D Preferred Shares shall be entitled to receive out of the assets of
the Company legally available for distribution or the proceeds thereof, after
payment or provision for debts and other liabilities of the Company, but before
any payment or distributions of the assets shall be made to holders of common
shares or any other class or series of shares of the Company that ranks junior
to the Series D Preferred Shares as to rights upon liquidation, dissolution or
winding-up of the Company, an amount equal to the sum of (i) a liquidation
preference of $50 per Series D Preferred Share, and (ii) an amount equal to any
accumulated and unpaid distributions thereon, whether or not declared, to the
date of payment. In the event that, upon such voluntary or involuntary
liquidation, dissolution or winding-up, there are insufficient assets to permit
full payment of liquidating distributions to the holders of Series D Preferred
Shares and any Parity Preferred Shares, all payments of liquidating
distributions on the Series D Preferred Shares and such Parity Preferred Shares
shall be made so that the payments on the Series D Preferred Shares and such
Parity Preferred Shares shall in all cases bear to each other the same ratio
that the respective rights of the Series D Preferred Shares and such other
Parity Preferred Shares (which shall not include any accumulation in respect of
unpaid distributions for prior distribution periods if such Parity Preferred
Shares do not have cumulative distribution rights) upon liquidation, dissolution
or winding-up of the Company bear to each other.

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Company, stating the payment date
or dates when, and the place or places where, the amounts distributable in such
circumstances shall be payable, shall be given by (i) fax and (ii) by registered
mail, postage pre-paid, not less than thirty (30) and not more than sixty (60)
days prior to the payment date stated therein, to each record holder of the
Series D Preferred Shares at the respective addresses of such holders as the
same shall appear on the share transfer records of the Company.

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series D Preferred
Shares will have no right or claim to any of the remaining assets of the
Company.

      (d) Consolidation, Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all of the property
or assets of the Company to, or the consolidation or merger or other business
combination of the Company with or into any corporation, trust or other entity
(or of any corporation, trust or other entity with or into the Company) shall
not be deemed to constitute a liquidation, dissolution or winding-up of the
Company.

      SECTION 5. Optional Redemption.
<PAGE>

      (a) Right of Optional Redemption. The Series D Preferred Shares may not be
redeemed prior to September 27, 2004. On or after such date, the Company shall
have the right to redeem the Series D Preferred Shares, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to $50 per share of Series D Preferred Shares plus accumulated and unpaid
distributions, whether or not declared, to the date of redemption. If fewer than
all of the outstanding Series D Preferred Shares are to be redeemed, the Series
D Preferred Shares to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional shares).

      (b) Limitation on Redemption. The Company may not redeem fewer than all of
the outstanding shares of Series D Preferred Shares unless all accumulated and
unpaid distributions have been paid on all outstanding Series D Preferred Shares
for all quarterly distribution periods terminating on or prior to the date of
redemption.

      (c) Procedures for Redemption. (i) Notice of redemption will be (i) faxed,
and (ii) mailed by the Company by registered mail, postage prepaid, not less
than thirty (30) nor more than sixty (60) days prior to the redemption date,
addressed to the respective holders of record of the Series D Preferred Shares
to be redeemed at their respective addresses as they appear on the transfer
records of the Company. No failure to give or defect in such notice shall affect
the validity of the proceedings for the redemption of any Series D Preferred
Shares except as to the holder to whom such notice was defective or not given.
In addition to any information required by law or by the applicable rules of any
exchange upon which the Series D Preferred Shares may be listed or admitted to
trading, each such notice shall state: (i) the redemption date, (ii) the
redemption price, (iii) the number of Series D Preferred Shares to be redeemed,
(iv) the place or places where such Series D Preferred Shares are to be
surrendered for payment of the redemption price, (v) that distributions on the
Series D Preferred Shares to be redeemed will cease to accumulate on such
redemption date and (vi) that payment of the redemption price and any
accumulated and unpaid distributions will be made upon presentation and
surrender of such Series D Preferred Shares. If fewer than all of the Series D
Preferred Shares held by any holder are to be redeemed, the notice mailed to
such holder shall also specify the number of Series D Preferred Shares held by
such holder to be redeemed.

            (ii) If the Company gives a notice of redemption in respect of
Series D Preferred Shares (which notice will be irrevocable) then, by 12:00
noon, New York City time, on the redemption date, the Company will deposit
irrevocably in trust for the benefit of the holders of the Series D Preferred
Shares being redeemed, funds sufficient to pay the applicable redemption price,
plus any accumulated and unpaid distributions, whether or not declared, if any,
on such shares to the date fixed for redemption, without interest, and will give
irrevocable instructions and authority to pay such redemption price and any
accumulated and unpaid distributions, whether or not declared, if any, on such
shares to the holders of the Series D Preferred Shares upon surrender of the
certificates for the Series D Preferred Shares by such holders at the place
designated in the notice of redemption. If fewer than all Series D Preferred
Shares evidenced by any certificate are being redeemed, a new certificate shall
be issued upon surrender of the certificate evidencing all Series D Preferred
Shares, evidencing the unredeemed Series D Preferred Shares without cost to the
holder thereof. On and after the date of redemption, distributions will cease to
accumulate on the Series D Preferred Shares or portions thereof called for
redemption, unless the Company defaults in the payment thereof. If any date
fixed for redemption of Series D Preferred Shares is not a Business Day, then
payment of the redemption price payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay) except that, if such Business Day falls in the
next calendar year, such payment will be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on such
date fixed for redemption. If payment of the redemption price or any accumulated
or unpaid distributions in respect of the Series D Preferred Shares is
improperly withheld or refused and not paid by the Company, distributions on
such Series D Preferred Shares will continue to accumulate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
applicable redemption price and any accumulated and unpaid distributions.

      (d) Status of Redeemed Shares. Any Series D Preferred Shares that shall at
any time have been redeemed shall after such redemption, have the status of
authorized but unissued Shares, without designation as to
<PAGE>

class or series until such shares are once more designated as part of a
particular class or series by the Board.

      SECTION 6. Voting Rights.

      (a) General. Holders of the Series D Preferred Shares will not have any
voting rights, except as set forth below.

      (b) Right to Elect Trustees. (i) If at any time full distributions shall
not have been timely made on any Series D Preferred Shares with respect to any
six (6) prior quarterly distribution periods, whether or not consecutive (a
"Preferred Distribution Default"), the holders of such Series D Preferred
Shares, voting together as a single class with the holders of each class or
series of Parity Preferred Shares upon which like voting rights have been
conferred and are exercisable, will have the right to elect two additional
Trustees to serve on the Company's Board (the "Preferred Shares Trustees") at a
special meeting called by the holders of record of at least 10% of the
outstanding Series D Preferred Shares or any such class or series of Parity
Preferred Shares or at the next annual meeting of Shareholders, and at each
subsequent annual meeting of Shareholders or special meeting for the election of
Trustees held in place thereof, until all such distributions in arrears and
distributions for the current quarterly period on the Series D Preferred Shares
and each such class or series of Parity Preferred Shares have been paid in full.

            (ii) At any time when such voting rights shall have vested, a proper
officer of the Company shall call or cause to be called, upon written request of
holders of record of at least 10% of the outstanding Series D Preferred Shares,
a special meeting of the holders of Series D Preferred Shares and all the series
of Parity Preferred Shares upon which like voting rights have been conferred and
are exercisable (collectively, the "Parity Securities") by mailing or causing to
be mailed to such holders a notice of such special meeting to be held not less
than ten and not more than 45 days after the date such notice is given. The
record date for determining holders of the Parity Securities entitled to notice
of and to vote at such special meeting will be the close of business on the
third Business Day preceding the day on which such notice is mailed. At any such
special meeting, all of the holders of the Parity Securities, by plurality vote,
voting together as a single class without regard to series will be entitled to
elect two Trustees on the basis of one vote per $25 of liquidation preference to
which such Parity Securities are entitled by their terms (excluding amounts in
respect of accumulated and unpaid dividends) and not cumulatively. The holder or
holders of one-third of the Parity Securities then outstanding, present in
person or by proxy, will constitute a quorum for the election of the Preferred
Shares Trustees except as otherwise provided by law. Notice of all meetings at
which holders of the Series D Preferred Shares shall be entitled to vote will be
given to such holders at their addresses as they appear in the transfer records.
At any such meeting or adjournment thereof in the absence of a quorum, subject
to the provisions of any applicable law, a majority of the holders of the Parity
Securities present in person or by proxy shall have the power to adjourn the
meeting for the election of the Preferred Shares Trustees, without notice other
than an announcement at the meeting, until a quorum is present. If a Preferred
Distribution Default shall terminate after the notice of a special meeting has
been given but before such special meeting has been held, the Company shall, as
soon as practicable after such termination, mail or cause to be mailed notice of
such termination to holders of the Series D Preferred Shares that would have
been entitled to vote at such special meeting.

            (iii) If and when all accumulated distributions and the
distributions for the current distribution period on the Series D Preferred
Shares shall have been paid in full or a sum sufficient for such payment is
irrevocably deposited in trust for payment, the holders of the Series D
Preferred Shares shall be divested of the voting rights set forth in this
Section 6(b) herein (subject to revesting in the event of each and every
Preferred Distribution Default) and, if all distributions in arrears and the
distributions for the current distribution period have been paid in full or set
aside for payment in full on all other classes or series of Parity Preferred
Shares upon which like voting rights have been conferred and are exercisable,
the term and office of each Preferred Shares Trustee so elected shall terminate.
Any Preferred Shares Trustee may be removed at any time with or without cause by
the vote of, and shall not be removed otherwise than by the vote of, the holders
of record of a majority of the outstanding Parity Securities when they have the
voting rights set forth in this Section 6(b). So long as a Preferred
Distribution Default shall continue, any vacancy in the office of a Preferred
Shares Trustee may be filled by written consent of the Preferred Shares Trustee
remaining in office, or if none remains in office, by a vote of the holders of
<PAGE>

record of a majority of the outstanding Parity Securities when they have the
voting rights set forth in this Section 6(b). The Preferred Shares Trustees
shall each be entitled to one vote per trustee on any matter.

      (c) Certain Voting Rights. So long as any Series D Preferred Shares remain
outstanding, the Company shall not, without the approval of the holders of at
least two-thirds of the Series D Preferred Shares outstanding at the time (i)
designate or create, or increase the authorized or issued amount of, any class
or series of shares ranking senior to the Series D Preferred Shares with respect
to payment of distributions or rights upon liquidation, dissolution or
winding-up of the Company or reclassify any authorized shares of the Company
into any such shares, or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such shares, (ii)
designate or create, or increase the authorized or issued amount of, any Parity
Preferred Shares or reclassify any authorized shares of the Company into any
such shares, or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such shares, but only
to the extent such Parity Preferred Shares are issued to an affiliate of the
Company, or (iii) either (A) consolidate, merge into or with, or convey,
transfer or lease its assets substantially as an entirety, to any corporation or
other entity, or (B) amend, alter or repeal the provisions of the Company's
Charter (including these Articles Supplementary) or Bylaws, whether by merger,
consolidation or otherwise, in each case that would materially and adversely
affect the powers, special rights, preferences, privileges or voting power of
the Series D Preferred Shares or the holders thereof, provided, however, that
with respect to the occurrence of a merger, consolidation or a sale or lease of
all or substantially all of the Company's assets as an entirety, so long as (a)
the Company is the surviving entity and the Series D Preferred Shares remain
outstanding with the terms thereof unchanged, or (b) the resulting, surviving or
transferee entity is a corporation organized under the laws of any state and
substitutes the Series D Preferred Shares for other preferred Shares having
substantially the same terms and same rights as the Series D Preferred Shares,
including with respect to distributions, voting rights and rights upon
liquidation, dissolution or winding-up of the Company, then the occurrence of
any such event shall not be deemed to materially and adversely affect such
rights, privileges or voting powers of the holders of the Series D Preferred
Shares and no vote of the Series D Preferred Shares shall be required; and
provided further that any increase in the amount of authorized Shares or the
creation or issuance of any other class or series of Shares, or any increase in
an amount of authorized shares of each class or series, in each case ranking
either (a) junior to the Series D Preferred Shares with respect to payment of
distributions and the distribution of assets upon liquidation, dissolution or
winding-up of the Company, or (b) on a parity with the Series D Preferred Shares
with respect to payment of distributions or the distribution of assets upon
liquidation, dissolution or winding-up of the Company to the extent such Shares
are not issued to an affiliate of the Company, shall not be deemed to materially
and adversely affect such rights, preferences, privileges or voting powers and
no approval of the Series D Preferred Shares shall be required.

      SECTION 7. Transfer Restrictions. The Series D Preferred Shares shall be
subject to the provisions of Article 3 of the Charter; provided, however, in no
event shall the Ownership Limit with respect to the Series D Preferred Shares
(as defined in the Charter) be decreased pursuant to Section 10 of Article 3 of
the Charter or otherwise (other than a decrease as a result of a retroactive
change in existing law that would require a decrease to retain real estate
investment trust status under the Internal Revenue Code of 1986, as amended).

      SECTION 8. No Conversion Rights. The holders of the Series D Preferred
Shares shall not have any rights to convert such shares into shares of any other
class or series of Shares or into any other securities of, or interest in, the
Company.

      SECTION 9. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of Series D Preferred Shares.

      SECTION 10. No Preemptive Rights. No holder of the Series D Preferred
Shares of the Company shall, as such holder, have any preemptive rights to
purchase or subscribe for additional Shares of the Company or any other security
of the Company which it may issue or sell.

            THIRD: The Series D Preferred Shares have been classified and
designated by the Board under the authority contained in the Charter.

                                FOURTH AMENDMENT
                                       TO
                           SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                        CABOT INDUSTRIAL PROPERTIES, L.P.

      This Fourth Amendment to Second Amended and Restated Agreement of Limited
Partnership (this "Amendment") is made as of December 9, 1999, by and among
CABOT INDUSTRIAL TRUST, a Maryland real estate investment trust, as general
partner (the "General Partner") of CABOT INDUSTRIAL PROPERTIES, L.P. (the
"Partnership"), for itself and on behalf of the limited partners of the
Partnership, and MONTEBELLO REALTY CORP., a Delaware corporation ("Montebello").

                                    Recitals

      Whereas, Section 4.2(a) of the Second Amended and Restated Agreement of
Limited Partnership of the Partnership, as amended by (i) that certain First
Amendment to Second Amended and Restated Agreement of Limited Partnership, dated
as of April 29, 1999, (ii) that certain Second Amendment to Second Amended and
Restated Agreement of Limited Partnership, dated as of September 3, 1999, and
(iii) that certain Third Amendment to Second Amended and Restated Agreement of
Limited Partnership, dated as of September 27, 1999 (collectively, as amended,
the "Partnership Agreement") authorizes the General Partner to cause the
Partnership to issue additional Partnership Units in one or more classes or
series, with such designations, preferences and relative, participating,
optional or other special rights, powers and duties as shall be determined by
the General Partner, subject to the provisions of such section; and

      Whereas, pursuant to the authority granted to the General Partner pursuant
to Sections 4.2(a) and 14. 1(b) of the Partnership Agreement, the General
Partner desires to amend the Partnership Agreement (i) to establish a new class
of Partnership Units, the Series E Preferred Units (as hereinafter defined), and
to set forth the designations, rights, powers, preferences and duties of such
Series E Preferred Units, (ii) to issue the Series E Preferred Units to
Montebello and admit Montebello as an Additional Limited Partner and (iii) to
make certain other changes to the Partnership Agreement.

      Now, therefore, in consideration of good and valuable consideration, the
receipt and sufficiency of which hereby are acknowledged, the General Partner
hereby amends the Partnership Agreement as follows:

      Section 1. Definitions. For purposes of this Amendment, the term "Series E
Parity Preferred Units" shall be used to refer to any class or series of
Partnership Interests of the Partnership now or hereafter authorized, issued or
outstanding expressly designated by the
<PAGE>

Partnership to rank on a parity with Series E Preferred Units with respect to
distributions and rights upon voluntary or involuntary liquidation, winding-up
or dissolution of the Partnership, including, without limitation, the Series B
Preferred Units, the Series C Preferred Units and the Preferred Series D Units.
The term "Series E Priority Return" shall mean, an amount equal to 8.375% per
annum, determined on the basis of a 360 day year of twelve 30 day months,
cumulative to the extent not distributed for any given distribution period
pursuant to Section 5.1 of the Partnership Agreement, of the stated value of $50
per Series E Preferred Unit, commencing on the date of issuance of such Series E
Preferred Unit. The term "Subsidiary" shall mean with respect to any person, any
corporation, partnership, limited liability company, joint venture or other
entity of which a majority of(i) voting power of the voting equity securities or
(ii) the outstanding equity interests, is owned, directly or indirectly, by such
person. The term "PTP" shall mean a "publicly traded partnership" within the
meaning of Section 7704 of the Code. Capitalized terms used herein and not
otherwise defined herein shall have the meanings ascribed to them in the
Partnership Agreement.

      Section 2. Designation and Number. A series of Partnership Units in the
Partnership designated as the "8.375% Series E Cumulative Redeemable Preferred
Units" (the "Series E Preferred Units") is hereby established. The number of
Series E Preferred Units shall be 200,000.

Section 3. Distributions.

            (a) Payment of Distributions. Subject to the rights of holders of
      Series E Parity Preferred Units as to the payment of distributions,
      pursuant to Section 5.1 of the Partnership Agreement, holders of Series E
      Preferred Units shall be entitled to receive, when, as and if declared by
      the Partnership acting through the General Partner, out of Available Cash,
      cumulative preferential cash distributions at the rate per annum of 8.375%
      of the original Capital Contribution per Series E Preferred Unit. Such
      distributions shall be cumulative, shall accrue from the original date of
      issuance and will be payable (i) quarterly in arrears, on March 31, June
      30, September 30 and December 31 of each year commencing on December 31,
      1999 and, (ii), in the event of (A) an exchange of Series E Preferred
      Units into Series E Preferred Shares, or (B) a redemption of Series E
      Preferred Units, on the exchange date or redemption date, as applicable
      (each a "Series E Preferred Unit Distribution Payment Date"). The amount
      of the distribution payable for any period will be computed on the basis
      of a 360-day year of twelve 30-day months and for any period shorter than
      a full quarterly period for which distributions are computed, the amount
      of the distribution payable will be computed on the basis of the actual
      number of days elapsed in such period. If any date on which distributions
      are to be made on the Series E Preferred Units is not a Business Day (as
      defined herein), then payment of the distribution to be made on such date
      will be made on the next succeeding day that is a Business Day (and
      without any interest or other payment in respect of any such delay) except
      that, if such Business Day is in the next succeeding calendar year, such
      payment shall be made on the immediately preceding Business Day, in each
      case with the same force and effect as if made on such date. Distributions
      on the Series E Preferred Units will be made to the holders of record of
      the Series E Preferred
<PAGE>

Units on the relevant record dates to be fixed by the Partnership acting through
the General Partner, which record dates shall in no event exceed fifteen (15)
Business Days prior to the relevant Series E Preferred Unit Distribution Payment
Date (the "Series E Preferred Unit Partnership Record Date").

      The term "Business Day" shall mean each day other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulations or executive order to close.

      (b) Distributions Cumulative. Distributions on the Series E Preferred
Units will accrue whether or not the terms and provisions of any agreement of
the Partnership, including any agreement relating to its indebtedness at any
time prohibit the current payment of distributions, whether or not the
Partnership has earnings, whether or not there are funds legally available for
the payment of such of such distributions and whether or not such distributions
are authorized. Accrued but unpaid distributions on the Series E Preferred Units
will accumulate as of the Series E Preferred Unit Distribution Payment Date on
which they first become payable. Distributions on account of arrears for any
past distribution periods may be declared and paid at any time, without
reference to a regular Series E Preferred Unit Distribution Payment Date to
holders of record of the Series E Preferred Units on the record date fixed by
the Partnership acting through the General Partner which date shall not exceed
fifteen (15) Business Days prior to the payment date. Accumulated and unpaid
distributions will not bear interest.

      (c) Priority as to Distributions.

            (i) So long as any Series E Preferred Units are outstanding, no
      distribution of cash or other property shall be authorized, declared, paid
      or set apart for payment on or with respect to any class or series of
      Partnership Interest of the Partnership ranking junior as to the payment
      of distributions or rights upon a voluntary or involuntary liquidation,
      dissolution or winding-up of the Partnership to the Series E Preferred
      Units (collectively, "Units Junior to Series E"), nor shall any cash or
      other property be set aside for or applied to the purchase, redemption or
      other acquisition for consideration of any Series E Preferred Units, any
      Series E Parity Preferred Units or any Units Junior to Series E, unless,
      in each case, all distributions accumulated on all Series E Preferred
      Units and all classes and series of outstanding Series E Parity Preferred
      Units have been paid in full. The foregoing sentence will not prohibit (a)
      distributions payable solely in Partnership Units ranking junior to the
      Series E Preferred Units as to distributions and upon liquidation,
      winding-up or dissolution, (b) the conversion of Units Junior to Series E
      or Series E Parity Preferred Units into Partnership Units ranking junior
      to the Series E Preferred Units as to distributions and upon liquidation,
      winding-up or dissolution or (c) the redemption of Partnership Interests
      corresponding to any Series E Preferred Shares (as hereinafter defined),
      Parity Preferred Shares (as such term is defined in the Charter) or Junior
      Shares (as such term is defined in the Charter) to be purchased
<PAGE>

      by the General Partner pursuant to Article 3 of the Declaration of Trust
      of the General Partner (the "Charter") to preserve the General Partner's
      status as a real estate investment trust, provided that such redemption
      shall be upon the same terms as the corresponding purchase pursuant to
      Article 3 of the Charter.

            (ii) So long as distributions have not been paid in full (or a sum
      sufficient for such full payment is not irrevocably deposited in trust for
      payment) upon the Series E Preferred Units, all distributions authorized
      and declared on the Series E Preferred Units and all classes or series of
      outstanding Series E Parity Preferred Units shall be authorized and
      declared so that the amount of distributions authorized and declared per
      Series E Preferred Unit and such other classes or series of Series E
      Parity Preferred Units shall in all cases bear to each other the same
      ratio that accrued distributions per Series E Preferred Unit and such
      other classes or series of Series E Parity Preferred Units (which shall
      not include any accumulation in respect of unpaid distributions for prior
      distribution periods if such class or series of Series E Parity Preferred
      Units do not have cumulative distribution rights) bear to each other.

      (d) No Further Rights. Holders of Series E Preferred Units shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

Section 4. Intentionally Omitted.

Section 5. Liquidation Proceeds.

      (a) Upon voluntary or involuntary liquidation, dissolution or winding-up
of the Partnership, distributions on the Series E Preferred Units shall be made
in accordance with Section 13.2 of the Partnership Agreement.

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the
Series E Preferred Units at the respective addresses of such holders as the same
shall appear on the transfer records of the Partnership.

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series E Preferred
Units will have no right or claim to any of the remaining assets of the
Partnership.

      (d) Consolidation, Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all of the property
or assets of the General Partner to,
<PAGE>

or the consolidation or merger or other business combination of the Partnership
with or into, any corporation, trust, partnership, limited liability company or
other entity (or of any corporation, trust, partnership, limited liability
company or other entity with or into the Partnership) shall not be deemed to
constitute a liquidation, dissolution or winding-tip of the Partnership.

Section 6. Optional Redemption.

      (a) Right of Optional Redemption. The Series E Preferred Units may not be
redeemed prior to the fifth (5th) anniversary of the issuance date. On or after
such date, the Partnership shall have the right to redeem the Series E Preferred
Units, in whole or in part, at any time or from time to time, upon not less than
thirty (30) nor more than sixty (60) days' written notice, at a redemption
price, payable in cash, equal to the Capital Account balance of the holders of
Series E Preferred Units (the "Series E Redemption Price"); provided, however,
that no redemption pursuant to this Section 6 will be permitted if the Series E
Redemption Price does not equal or exceed the original Capital Contribution of
such holder plus the cumulative Series E Priority Return, whether or not
declared, to the redemption date to the extent not previously distributed or
distributed pursuant to Section 3(a). If fewer than all of the outstanding
Series E Preferred Units are to be redeemed, the Series E Preferred Units to be
redeemed shall be selected pro rata (as nearly as practicable without creating
fractional units).

      (b) Limitation on Redemption. The Partnership may not redeem fewer than
all of the outstanding Series E Preferred Units unless all accumulated and
unpaid distributions have been paid on all Series E Preferred Units for all
quarterly distribution periods terminating on or prior to the date of
redemption.

(c) Procedures for Redemption.

            (i) Notice of redemption will be (A) faxed, and (B) mailed by the
      Partnership, by certified mail, postage prepaid, not less than thirty (30)
      nor more than sixty (60) days prior to the redemption date, addressed to
      the respective holders of record of the Series E Preferred Units at their
      respective addresses as they appear on the records of the Partnership. No
      failure to give or defect in such notice shall affect the validity of the
      proceedings for the redemption of any Series E Preferred Units except as
      to the holder to whom such notice was defective or not given. In addition
      to any information required by law, each such notice shall state: (1) the
      redemption date, (2) the Series E Redemption Price, (3) the aggregate
      number of Series E Preferred Units to be redeemed and if fewer than all of
      the outstanding Series E Preferred Units are to be redeemed, the number of
      Series E Preferred Units to be redeemed held by such holder, which number
      shall equal such holder's pro rata share (based on the percentage of the
      aggregate number of outstanding Series E Preferred Units the total number
      of Series E Preferred Units held by such holder represents) of the
      aggregate number of Series E Preferred Units to be redeemed, (4) the place
      or places where such
<PAGE>

      Series E Preferred Units are to be surrendered for payment of the Series E
      Redemption Price, (5) that distributions on the Series E Preferred Units
      to be redeemed will cease to accumulate on such redemption date and (6)
      that payment of the Series E Redemption Price will be made upon
      presentation and surrender of such Series E Preferred Units.

            (ii) If the Partnership gives a notice of redemption in respect of
      Series E Preferred Units (which notice will be irrevocable) then, by 12:00
      noon, New York City time, on the redemption date, the Partnership will
      deposit irrevocably in trust for the benefit of the Series E Preferred
      Units being redeemed funds sufficient to pay the applicable Series E
      Redemption Price and will give irrevocable instructions and authority to
      pay such Series E Redemption Price to the holders of the Series E
      Preferred Units upon surrender of the Series E Preferred Units by such
      holders at the place designated in the notice of redemption. If the Series
      E Preferred Units are evidenced by a certificate and if fewer than all
      Series E Preferred Units evidenced by any certificate are being redeemed,
      a new certificate shall be issued upon surrender of the certificate
      evidencing all Series E Preferred Units, evidencing the unredeemed Series
      F Preferred Units without cost to the holder thereof. On and after the
      date of redemption, distributions will cease to accumulate on the Series E
      Preferred Units or portions thereof called for redemption, unless the
      Partnership defaults in the payment thereof. If any date fixed for
      redemption of Series E Preferred Units is not a Business Day, then payment
      of the Series E Redemption Price payable on such date will be made on the
      next succeeding day that is a Business Day (and without any interest or
      other payment in respect of any such delay) except that, if such Business
      Day falls in the next calendar year, such payment will be made on the
      immediately preceding Business Day, in each case with the same force and
      effect as if made on such date fixed for redemption. If payment of the
      Series E Redemption Price is improperly withheld or refused and not paid
      by the Partnership, distributions on such Series E Preferred Units will
      continue to accumulate from the original redemption date to the date of
      payment, in which case the actual payment date will be considered the date
      fixed for redemption for purposes of calculating the applicable Series E
      Redemption Price.

Section 7. Voting Rights.

      (a) General. Holders of the Series E Preferred Units will not have any
voting rights or right to consent to any matter requiring the consent or
approval of the Limited Partners, except as set forth in the Partnership
Agreement and except as set forth below.

      (b) Certain Voting Rights. So long as any Series E Preferred Units remain
outstanding, the Partnership shall not, without the affirmative vote of the
holders of at least two-thirds of the Series E Preferred Units outstanding at
the time (i) authorize or create, or increase the authorized or issued amount
of, any class or series of Partnership Interests senior to the Series E
Preferred Units with respect to payment of distributions or
<PAGE>

      rights upon liquidation, dissolution or winding-up of the Partnership or
      reclassify any Partnership Interests of the Partnership into any such
      senior Partnership Interest, or create, authorize or issue any obligations
      or security convertible into or evidencing the right to purchase any such
      senior Partnership Interests, (ii) authorize or create, or increase the
      authorized or issued amount of any Series E Parity Preferred Units or
      reclassify any Partnership Interest into any such Partnership Interest or
      create, authorize or issue any obligations or security convertible into or
      evidencing the right to purchase any such Partnership Interests but only
      to the extent such Series E Parity Preferred Units are issued to an
      Affiliate of the Partnership, other than the General Partner to the extent
      the issuance of such interests was to allow the General Partner to issue
      corresponding preferred stock to persons who are not Affiliates of the
      Partnership (or to Affiliates purchasing the preferred stock on the same
      terms as non-affiliated purchasers) or (iii) either (A) consolidate, merge
      into or with, or convey, transfer or lease all or substantially all of its
      assets to, any corporation or other entity or (B) amend, alter or repeal
      the provisions of the Partnership Agreement, whether by merger,
      consolidation or otherwise, that would materially and adversely affect the
      powers, special rights, preferences, privileges or voting power of the
      Series E Preferred Units or the holders thereof, provided, however, that
      with respect to the occurrence of a merger, consolidation or a sale or
      lease of all or substantially all of the Partnership's assets as an
      entirety, so long as (1) the Partnership is the surviving entity and the
      Series E Preferred Units remain outstanding with the terms thereof
      unchanged, or (2) the resulting, surviving or transferee entity is a
      partnership, limited liability company or other pass-through entity
      organized under the laws of any state and substitutes the Series E
      Preferred Units for other interests in such entity having substantially
      the same terms and rights as the Series E Preferred Units, including with
      respect to distributions, voting rights and rights upon liquidation,
      dissolution or winding-up of the Partnership, then the occurrence of any
      such event shall not be deemed to materially and adversely affect such
      rights, privileges or voting powers of the holders of the Series E
      Preferred Units and no vote of the Series E Preferred Units shall be
      required in such case; and provided further that any increase in the
      amount of Partnership Interests or the creation or issuance of any other
      class or series of Partnership Interests, in each case ranking (y) junior
      to the Series E Preferred Units with respect to payment of distributions
      or the distribution of assets upon liquidation, dissolution or winding-up
      of the Partnership, or (z) on a parity with the Series E Preferred Units
      with respect to payment of distributions and the distribution of assets
      upon liquidation, dissolution or winding-up of the Partnership to the
      extent such Partnership Interests are issued to an affiliate of the
      Partnership, other than the General Partner to the extent the issuance of
      such interests was to allow the General Partner to issue corresponding
      preferred stock to persons who are not affiliates of the Partnership,
      shall not be deemed to materially and adversely affect such rights,
      preferences, privileges or voting powers and no vote of the Series E
      Preferred Units shall be required in such case.

      Section 8. Transfer Restrictions. The Series E Preferred Units shall be
subject to the provisions of Article XI of the Partnership Agreement, provided,
however, that (i) the General Partner shall act reasonably in exercising its
discretion pursuant to the provisions of Section 1l.4(a)(ii) to transferees of
Series E Preferred Units, (ii) the provisions of Clause B of
<PAGE>

Section 11.3(d) shall not be applicable to holders of Series E Preferred Units
if at the time of such transfer, the Partnership already has 100 Partners; (iii)
if only a portion of the Series E Preferred Units shall be transferred, the
transferee of such transferred Series E Preferred Units shall, subject to the
provisions of Section 11.4, be substituted as a Limited Partner in place of the
transferring holders only as to the Series E Preferred Units so transferred; and
(iv) the provisions of Sections 11.6(c) and 11.6(d) shall not be applicable to
any transfer of Series E Preferred Units; and provided further that "transfer"
when used in Article 11 shall not be deemed to include any exchange pursuant to
Section 9 below.

      Section 9. Exchange Rights.

            (a) Right to Exchange.

                  (i) Series E Preferred Units will be exchangeable in whole or
            in part at anytime on or after the tenth (10th) anniversary of the
            date of issuance, at the option of the holders thereof, for
            authorized but previously unissued shares of 8.375% Series E
            Cumulative Redeemable Preferred Shares of the General Partner (the
            "Series E Preferred Shares") at an exchange rate of one Series E
            Preferred Share for one Series E Preferred Unit, subject to
            adjustment as described below (the "Series E Exchange Price"),
            provided that the Series E Preferred Units will become exchangeable
            at any time, in whole or in part, at the option of the holders of
            Series E Preferred Units for Series E Preferred Shares if(y) at any
            time full distributions shall not have been timely made on any
            Series E Preferred Unit with respect to six (6) prior quarterly
            distribution periods, whether or not consecutive, provided, however,
            that a distribution in respect of Series E Preferred Units shall be
            considered timely made if made within two (2) Business Days after
            the applicable Series E Preferred Unit Distribution Payment Date if
            at the time of such late payment there shall not be any prior
            quarterly distribution periods in respect of which full
            distributions were not timely made or (z) upon receipt by a holder
            or holders of Series E Preferred Units of (1) a notice from the
            General Partner that the General Partner or a Subsidiary of the
            General Partner has taken the position that the Partnership is, or
            upon the occurrence of a defined event in the immediate future will
            be, a PTP and (2) an opinion rendered by an outside nationally
            recognized independent counsel familiar with such matters addressed
            to a holder or holders of Series E Preferred Units, that the
            Partnership is or likely is, or upon the occurrence of a defined
            event in the immediate future will be or likely will be, a PTP. In
            addition, the Series E Preferred Units may be exchanged for Series E
            Preferred Shares, in whole or in part, at the option of any holder
            prior to the tenth (10th) anniversary of the issuance date and after
            the third (3rd) anniversary thereof if such holder of a Series E
            Preferred Units shall deliver to the General Partner either (i) a
            private letter ruling addressed to such holder of Series E Preferred
            Units or (ii) an opinion of independent counsel reasonably
            acceptable to the General Partner based on the enactment of
            temporary or final Treasury Regulations or the publication of a
            Revenue Ruling, in either case to the effect that an exchange of the
            Series E Preferred Units at such earlier time would not
<PAGE>

            cause the Series E Preferred Units to be considered "stock and
            securities" within the meaning of section 351(e) of the Code for
            purposes of determining whether the holder of such Series E
            Preferred Units is an "investment company" under section 721(b) of
            the Code if an exchange is permitted at such earlier date.
            Furthermore, all the Series E Preferred Units held by any holder
            thereof which is a real estate investment trust within the meaning
            of Sections 856 through 859 of the Code for Series E Preferred
            Shares may be exchanged in whole but not in part (but only if the
            exchange may be accomplished consistently with the ownership
            limitations set forth under Article 3 of the Charter (taking into
            account exceptions thereto)) if at any time, (i) the Partnership
            reasonably determines that the assets and income of the Partnership
            for a taxable year after 1999 would not satisfy the income and
            assets tests of Section 856 of the Code for such taxable year if the
            Partnership were a real estate investment trust within the meaning
            of the Code or (ii) any such holder of Series E Preferred Units
            shall deliver to the Partnership and the General Partner an opinion
            of independent counsel reasonably acceptable to the General Partner
            to the effect that, based on the assets and income of the
            Partnership for a taxable year after 1999, the Partnership would not
            satisfy the income and assets tests of Section 856 of the Code for
            such taxable year if the Partnership were a real estate investment
            trust within the meaning of the Code and that such failure would
            create a meaningful risk that a holder of the Series E Preferred
            Units would fail to maintain qualification as a real estate
            investment trust.

                  (ii) Notwithstanding anything to the contrary set forth in
            Section 9(a)(i) hereof, if an Series E Exchange Notice (as defined
            herein) has been delivered to the General Partner, then the General
            Partner may, at its option, elect to redeem or cause the Partnership
            to redeem all or a portion of the outstanding Series E Preferred
            Units for cash in an amount equal to the original Capital
            Contribution per Series E Preferred Unit and all accrued and unpaid
            distributions thereon to the date of redemption. The General Partner
            may exercise its option to redeem the Series E Preferred Units for
            cash pursuant to this Section 9(a)(ii) hereof by giving each holder
            of record of Series E Preferred Units notice of its election to
            redeem for cash, within five (5) Business Days after receipt of the
            Series E Exchange Notice, by (y) fax, and (z) registered mail,
            postage paid, at the address of each holder as it may appear on the
            records of the Partnership stating (A) the redemption date, which
            shall be no later than sixty (60) days following the receipt of the
            Series E Exchange Notice, (B) the redemption price, (C) the place or
            places where the Series E Preferred Units are to be surrendered for
            payment of the redemption price, (D) that distributions on the
            Series E Preferred Units will cease to accrue on such redemption
            date; (F) that payment of the redemption price will be made upon
            presentation and surrender of the Series E ______ Preferred Units
            and (F) the aggregate number of Series E Preferred Units to be
            redeemed, and if fewer than all of the outstanding Series E
            Preferred Units are to be redeemed, the number of Series E Preferred
            Units to be redeemed held by such holder, which number shall equal
            such holder's pro-rata share (based on the percentage of the
<PAGE>

            aggregate number of outstanding Series E Preferred Units the total
            number of Series E Preferred Units held by such holder represents)
            of the aggregate number of Series E Preferred Units being redeemed.

                  (iii) In the event an exchange of all or a portion of Series E
            Preferred Units pursuant to Section 9(a)(i) hereof would violate the
            provisions on ownership limitation of the General Partner set forth
            in Article 3 of the Charter with respect to the Series E Preferred
            Shares, the General Partner shall give written notice thereof to
            each holder of record of Series E Preferred Units, within five (5)
            Business Days following receipt of the Series E Exchange Notice, by
            (y) fax, and (z) registered mail, postage prepaid, at the address of
            each such holder set forth in the records of the Partnership. In
            such event, each holder of Series E Preferred Units shall be
            entitled to exchange, pursuant to the provision of Section 9(b) a
            number of Series E Preferred Units which would comply with the
            provisions on the ownership limitation of the General Partner set
            forth in such Article 3 of the Charter and any Series E Preferred
            Units not so exchanged (the "Series E Excess Units") shall be
            redeemed by the Partnership for cash in an amount equal to the
            original Capital Contribution per Excess Unit, plus any accrued and
            unpaid distributions thereon, whether or not declared, to the date
            of redemption. The written notice of the General Partner shall state
            (A) the number of Series E Excess Units held by such holder, (B) the
            redemption price of the Series E Excess Units, (C) the date on which
            such Series E Excess Units shall be redeemed, which date shall be no
            later than sixty (60) days following the receipt of the Series E
            Exchange Notice, (D) the place or places where such Series E Excess
            Units are to be surrendered for payment of the Series E Redemption
            Price, (E) that distributions on the Series E Excess Units will
            cease to accrue on such redemption date, and (F) that payment of the
            redemption price will be made upon presentation and surrender of
            such Series E Excess Units. In the event an exchange would result in
            Series E Excess Units, as a condition to such exchange, each holder
            of such units agrees to provide representations and covenants
            reasonably requested by the General Partner relating to (1) the
            widely held nature of the interests in such holder, sufficient to
            assure the General Partner that the holder's ownership of stock of
            the General Partner (without regard to the limits described above)
            will not cause any individual to Beneficially Own in excess of the
            Ownership Limit (all as defined in the General Partner's Charter);
            and (2) to the extent such holder can so represent and covenant
            without obtaining information from its owners, the holder's
            ownership of tenants of the Partnership and its affiliates.

                  (iv) The redemption of Series E Preferred Units described in
            Section 9(a)(ii) and (iii) shall be subject to the provisions of
            Section 6(b)(i) and Section 6(c)(ii); provided, however, that the
            term "Series E Redemption Price" in such Section shall be read to
            mean the original Capital Contribution per Series E Preferred Unit
            being redeemed plus all accrued and unpaid distributions to the
            redemption date.

            (b) Procedure for Exchange.

                  (i) Any exchange shall be exercised pursuant to a notice of
            exchange (the "Series E Exchange Notice") delivered to the General
            Partner by the holder who is exercising such exchange right, by (A)
            fax and (B) by certified mail postage prepaid. The exchange of
            Series E Preferred Units, or a specified portion thereof, may be
            effected after the fifth (5th) Business Day following receipt by the
            General Partner of the Series E Exchange Notice by delivering
            certificates, if any, representing such Series E Preferred Units to
            be exchanged together with, if applicable, written notice of
            exchange and a proper assignment of such Series E Preferred Units to
            the office of the General Partner maintained for such purpose.
            Currently, such office is Two Center Plaza, Suite 200, Boston,
            Massachusetts 02108. Each exchange will be deemed to have been
            effected immediately prior to the close of business on the date on
            which such Series E Preferred Units to be exchanged (together with
            all required documentation) shall have been surrendered and notice
            shall have been received by the General Partner as aforesaid and the
            Series E Exchange Price shall have been paid. Any Series E Preferred
            Shares issued pursuant to this Section 9 shall be delivered as
            shares which are duly authorized, validly issued, fully paid and
            nonassessable, free of pledge, lien, encumbrance or restriction
            other than those provided in the Charter, the Bylaws of the General
            Partner, the Securities Act and relevant state securities or blue
            sky laws.

                  (ii) In the event of an exchange of Series E Preferred Units
            for Series E Preferred Shares, an amount equal to the accrued and
            unpaid distributions, whether or not declared, to the date of
            exchange on any Series E Preferred Units tendered for exchange shall
            (A) accrue on the Series E Preferred Shares into which such Series E
            Preferred Units are exchanged, and (B) continue to accrue on such
            Series E Preferred Units, which shall remain outstanding following
            such exchange, with the General Partner as the holder of such Series
            F Preferred Units. Notwithstanding anything to the contrary set
            forth herein, in no event shall a holder of a Series E Preferred
            Unit that was validly exchanged into Series E Preferred Shares
            pursuant to this section (other than the General Partner now holding
            such Series E Preferred Unit), receive a cash distribution out of
            Available Cash of the Partnership, if such holder, after exchange,
            is entitled to receive a distribution out of Available Cash with
            respect to the Series E Preferred Shares for which such Series E
            Preferred Unit was exchanged or redeemed.

                  (iii) Fractional shares of Series E Preferred Shares are not
            to be issued upon exchange but, in lieu thereof, the General Partner
            will pay a cash adjustment based upon the fair market value of the
            Series E Preferred Shares on the day prior to the exchange date as
            determined in good faith by the Board of Directors of the General
            Partner.

      (c) Adjustment of Series E Exchange Price.
<PAGE>

                  (i) The Series E Exchange Price is subject to adjustment upon
            certain events, including, (A) subdivisions, combinations and
            reclassification of the Series E Preferred Shares, and (B)
            distributions to all holders of Series E Preferred Shares of
            evidence of indebtedness of the General Partner or assets (including
            securities, but excluding dividends and distributions paid in cash
            out of equity applicable to Series E Preferred Shares).

                  (ii) In case the General Partner shall be a party to any
            transaction (including, without limitation, a merger, consolidation,
            statutory share exchange, tender offer for all or substantially all
            of the General Partner's capital stock or sale of all or
            substantially all of the General Partner's assets), in each case as
            a result of which the Series E Preferred Shares will be converted
            into the right to receive shares of capital stock, other securities
            or other property (including cash or any combination thereof), each
            Series E Preferred Unit will thereafter be exchangeable into the
            kind and amount of shares of capital stock and other securities and
            property receivable (including cash or any combination thereof) upon
            the consummation of such transaction by a holder of that number of
            Series E Preferred Shares or fraction thereof into which one Series
            F Preferred Unit was exchangeable immediately prior to such
            transaction. The General Partner may not become a party to any such
            transaction unless the terms thereof are consistent with the
            foregoing.

      Section 10. No Conversion Rights.

            (a) The holders of the Series E Preferred Units shall not have any
      rights to convert such shares into shares of any other class or series of
      shares or into any other securities of, or interest in, the Partnership.

            (b) The Series E Preferred Units shall not be subject to the
      provisions of Section 4.2(e) of the Partnership Agreement.

      Section 11. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of Series E Preferred Units.

      Section 12. Admission of Limited Partner; Exhibits to Partnership
Agreement. In accordance with Section 12.2(b), Montebello is hereby admitted as
an Additional Limited Partner. In order to duly reflect the issuance of Series E
Preferred Units provided for herein, the Partnership Agreement is hereby amended
by deleting Exhibit A attached thereto and substituting Exhibit A attached
hereto therefor.

      Section 13. Reaffirmation. Except as modified herein, all terms and
conditions of the Partnership Agreement shall remain in full force and effect,
which terms and conditions the General Partner hereby ratifies and affirms.

             8.375% SERIES E CUMULATIVE REDEEMABLE PREFERRED SHARES

      Cabot Industrial Trust, a Maryland real estate investment trust (the
"Company"), hereby certifies to the State Department of Assessments and Taxation
of Maryland (the "Department") that:

            FIRST: Under a power contained in Article 2, Section 1 of the
      Amended and Restated Declaration of Trust of the Company, filed with, and
      accepted for record by, the State Department of Assessments and Taxation
      of Maryland (the "SDAT") on January 26, 1998, as supplemented by Articles
      Supplementaries filed with, and accepted for record by, the SDAT
      respectively on July 10, 1998, April 29, 1999, September 3, 1999 and
      September 27, 1999 and as corrected by that certain Certificate of
      Correction filed with, and accepted for record by, the SDAT on October 12,
      1999 (collectively, as supplemented and corrected, the "Charter"), the
      Board of Trustees of the Company, as required by Section 8-203(b) of the
      Corporations and Associations Article of the Annotated Code of Maryland,
      has unanimously adopted resolutions classifying and designating 200,000
      unissued shares of beneficial interest (the "Shares") as 8.375% Series E
      Cumulative Redeemable Preferred Shares, with the following preferences,
      conversion and other rights, voting powers, restrictions, limitations as
      to dividends and other distributions, qualifications and terms and
      conditions of redemption, and other terms and conditions, which upon any
      restatement of the Charter shall be made part of Article 2 of the Charter,
      with any necessary or appropriate changes to the enumeration and lettering
      thereof:

            SECOND: The following is a description of the 8.375% Series E
      Cumulative Redeemable Preferred Shares, including the preferences,
      conversion and other rights, voting powers, restrictions, limitations as
      to dividends, qualifications and terms and conditions of redemption
      thereof:

             8.375% SERIES E CUMULATIVE REDEEMABLE PREFERRED SHARES

                  Section 1. Designation and Number. A series of preferred
            shares, designated the "8.375% Series E Cumulative Redeemable
            Preferred Shares" (the "Series E Preferred Shares") is hereby
            established. The number of shares of Series E Preferred Shares shall
            be 200,000.
<PAGE>

                  Section 2. Rank. The Series E Preferred Shares shall, with
            respect to distributions and rights upon voluntary or involuntary
            liquidation, winding-up or dissolution of the Company, rank senior
            to all classes or series of common Shares and to all classes or
            series of equity securities of the Company now or hereafter
            authorized, issued or outstanding, other than any class or series of
            equity securities of the Company expressly designated as ranking on
            a parity with or senior to the Series E Preferred Shares as to
            distributions and rights upon voluntary or involuntary liquidation,
            winding-up or dissolution of the Company. For purposes of these
            Articles Supplementary, the term "Series E Parity Preferred Shares"
            shall be used to refer to the Series B Cumulative Redeemable Shares
            (authorized pursuant to that certain Articles Supplementary filed
            with the SDAT on April 29, 1999), the Series C Cumulative Redeemable
            Preferred Shares (authorized pursuant to that certain Articles
            Supplementary filed with the SDAT on September 3, 1999), the Series
            D Cumulative Redeemable Preferred Shares (authorized pursuant to
            that certain Articles Supplementary filed with the SDAT on September
            27, 1999) and any class or series of equity securities of the
            Company now or hereafter authorized, issued or outstanding expressly
            designated by the Company to rank on a parity with Series E
            Preferred Shares with respect to distributions and rights upon
            voluntary or involuntary liquidation, winding-up or dissolution of
            the Company. The term "equity securities" does not include debt
            securities, which will rank senior to the Series E Preferred Shares
            prior to conversion.

                  Section 3. Distributions.

                        (a) Payment of Distributions. Subject to the rights of
                  holders of Series E Parity Preferred Shares and holders of
                  equity securities ranking senior to the Series E Preferred
                  Shares as to payment of distributions, holders of Series E
                  Preferred Shares will be entitled to receive, when, as and if
                  declared by the Board of Trustees of the Company, out of funds
                  legally available for the payment of distributions, cumulative
                  preferential cash distributions at the rate per annum of
                  8.375% of the $50 liquidation preference per Series E
                  Preferred Share. Such distributions shall be cumulative, shall
                  accrue from the original date of issuance and will be payable
                  (i) quarterly in arrears, on March 31, June 30, September 30
                  and December 31 of each year commencing on the first of such
                  dates to occur after the original date of issuance and, (ii)
                  in the event of a redemption, on the redemption date (each a
                  "Series E Preferred Shares Distribution Payment Date"). The
                  amount of the distribution payable for any period will be
                  computed on the basis of a 360-day year of twelve 30-day
                  months and for any period shorter than a full quarterly period
                  for which distributions are computed, the amount of the
                  distribution payable will be computed on the basis of the
                  actual number of days elapsed in such period. If any date on
                  which distributions are to be made on the Series E Preferred
<PAGE>

                  Shares is not a Business Day (as defined herein), then payment
                  of the distribution to be made on such date will be made on
                  the next succeeding day that is a Business Day (and without
                  any interest or other payment in respect of any such delay)
                  except that, if such Business Day is in the next succeeding
                  calendar year, such payment shall be made on the immediately
                  preceding Business Day, in each case with the same force and
                  effect as if made on such date. Distributions on the Series E
                  Preferred Shares will be made to the holders of record of the
                  Series E Preferred Shares on the relevant record dates, which,
                  unless otherwise provided by the Company with respect to any
                  distribution, will be fifteen (15) Business Days prior to the
                  relevant Series E Preferred Shares Distribution Payment Date
                  (each a "Series E Distribution Record Date"). Notwithstanding
                  anything to the contrary set forth herein, each Series E
                  Preferred Share shall also continue to accrue all accrued and
                  unpaid distributions up to the exchange date on any Series E
                  Preferred Unit (as defined in the Second Amended and Restated
                  Agreement of Limited Partnership of Cabot Industrial
                  Properties, L.P., dated as of February 4, 1998 (the
                  "Partnership Agreement"), as amended through the date hereof)
                  validly exchanged into such Series E Preferred Share in
                  accordance with the provisions of such Partnership Agreement.

                        The term "Business Day" shall mean each day, other than
                  a Saturday or a Sunday, which is not a day on which banking
                  institutions in New York, New York are authorized or required
                  by law, regulation or executive order to close.

                        (b) Limitation on Distributions. No distributions on the
                  Series E Preferred Shares shall be declared or paid or set
                  apart for payment by the Company at such time as the terms and
                  provisions of any agreement of the Company, including any
                  agreement relating to its indebtedness, prohibits such
                  declaration, payment or setting apart for payment or provides
                  that such declaration, payment or setting apart for payment
                  would constitute a breach thereof or a default thereunder, or
                  if such declaration, payment or setting apart for payment
                  shall be restricted or prohibited by law.

                        (c) Distributions Cumulative. Notwithstanding the
                  foregoing, distributions on the Series E Preferred Shares will
                  accrue whether or not the terms and provisions set forth in
                  Section 3(b) hereof at any time prohibit the current payment
                  of distributions, whether or not the Company has earnings,
                  whether or not there are funds legally available for the
                  payment of such distributions and whether or not such
                  distributions are authorized or declared. Accrued but unpaid
                  distributions on the Series E Preferred Shares will accumulate
                  as of the Series E Preferred Shares Distribution Payment Date
                  on which they first become payable. Accumulated and unpaid
                  distributions will not bear interest.

                        (d) Priority as to Distributions.

                              (i) So long as any Series E Preferred Shares are
                        outstanding, no distribution of cash or other property
                        shall be authorized, declared, paid or set apart for
                        payment on or with respect to any class or series of
                        common Shares or any class or series of other Shares of
                        the Company ranking junior as to the payment of
                        distributions or rights upon voluntary or involuntary
                        dissolution, liquidation or winding up of the Company to
                        the Series E Preferred Shares (such common Shares or
                        other junior Shares, including, without limitation
                        Series A Junior Participating Preferred Shares
                        authorized pursuant to Articles Supplementary filed with
                        the Department on July 10, 1998 collectively, "Shares
                        Junior to Series E"), nor shall any cash or other
                        property be set aside for or applied to the purchase,
                        redemption or other acquisition for consideration of any
                        Series E Preferred Shares, any Series E Parity Preferred
                        Shares or any Shares Junior to Series E, unless, in each
                        case, all distributions accumulated on all Series E
                        Preferred Shares and all classes and series of
                        outstanding Series E Parity Preferred Shares have been
                        paid in full. The foregoing sentence will not prohibit
                        (i) distributions payable solely in Shares of the
                        Company ranking junior to the Series E Preferred Shares
                        as to distributions and upon liquidation, winding-up or
                        dissolution, (ii) the conversion of Shares Junior to
                        Series E or Series E Parity Preferred Shares into Shares
                        of the Company ranking junior to the Series E Preferred
                        Shares as to distributions and upon liquidation,
                        winding-up or dissolution, and (iii) purchase by the
                        Company of such Series E Preferred Shares, Series E
                        Parity Preferred Shares or Shares Junior to Series E
                        pursuant to Article 3 of the Charter to the extent
                        required to preserve the Company's status as a real
                        estate investment trust.

                              (ii) So long as distributions have not been paid
                        in full (or a sum sufficient for such full payment is
                        not irrevocably deposited in trust for payment) upon the
                        Series E Preferred Shares, all distributions authorized
                        and declared on the Series E Preferred Shares and all
                        classes or series of outstanding Series E Parity
                        Preferred Shares shall be authorized and declared so
                        that the amount of distributions authorized and declared
                        per share of Series E Preferred Shares and such other
                        classes or series of Series E Parity Preferred Shares
                        shall in all cases bear to each other the same ratio
                        that accrued distributions per share on the Series E
                        Preferred Shares and such other classes or series of
                        Series E Parity Preferred Shares (which shall not
                        include any accumulation in
<PAGE>

                        respect of unpaid distributions for prior distribution
                        periods if such class or series of Series E Parity
                        Preferred Shares do not have cumulative distribution
                        rights) bear to each other.

                        (e) No Further Rights. Holders of Series E Preferred
                  Shares shall not be entitled to any distributions, whether
                  payable in cash, other property or otherwise, in excess of the
                  full cumulative distributions described herein.

                  Section 4. Liquidation Preference.

                        (a) Payment of Liquidation Distributions. Subject to the
                  rights of holders of Series E Parity Preferred Shares and
                  subject to equity securities ranking senior to the Series E
                  Preferred Shares with respect to rights upon any voluntary or
                  involuntary liquidation, dissolution or winding-up of the
                  Company, the holders of Series E Preferred Shares shall be
                  entitled to receive out of the assets of the Company legally
                  available for distribution or the proceeds thereof, after
                  payment or provision for debts and other liabilities of the
                  Company, but before any payment or distributions of the assets
                  shall be made to holders of common Shares or any other class
                  or series of shares of the Company that ranks junior to the
                  Series E Preferred Shares as to rights upon liquidation,
                  dissolution or winding-up of the Company, an amount equal to
                  the sum of (i) a liquidation preference of $50 per Series E
                  Preferred Share, and (ii) an amount equal to any accumulated
                  and unpaid distributions thereon, whether or not declared, to
                  the date of payment. In the event that, upon such voluntary or
                  involuntary liquidation, dissolution or winding-up, there are
                  insufficient assets to permit full payment of liquidating
                  distributions to the holders of Series E Preferred Shares and
                  any Series E Parity Preferred Shares, all payments of
                  liquidating distributions on the Series E Preferred Shares and
                  such Series E Parity Preferred Shares shall be made so that
                  the payments on the Series E Preferred Shares and such Series
                  E Parity Preferred Shares shall in all cases bear to each
                  other the same ratio that the respective rights of the Series
                  E Preferred Shares and such other Series E Parity Preferred
                  Shares (which shall not include any accumulation in respect of
                  unpaid distributions for prior distribution periods if such
                  Series E Parity Preferred Shares do not have cumulative
                  distribution rights) upon liquidation, dissolution or
                  winding-up of the Company bear to each other.

                        (b) Notice. Written notice of any such voluntary or
                  involuntary liquidation, dissolution or winding-up of the
                  Company, stating the payment date or dates when, and the place
                  or places where, the amounts distributable in such
                  circumstances shall be payable, shall be given by (i) fax and
                  (ii) by first class mail, postage pre-paid, not less than
<PAGE>

                  thirty (30) and not more than sixty (60) days prior to the
                  payment date stated therein, to each record holder of the
                  Series E Preferred Shares at the respective addresses of such
                  holders as the same shall appear on the share transfer records
                  of the Company.

                        (c) No Further Rights. After payment of the full amount
                  of the liquidating distributions to which they are entitled,
                  the holders of Series E Preferred Shares will have no right or
                  claim to any of the remaining assets of the Company.

                        (d) Consolidation, Merger or Certain Other Transactions.
                  The voluntary sale, conveyance, lease, exchange or transfer
                  (for cash, shares of stock, securities or other consideration)
                  of all or substantially all of the property or assets of the
                  Company to, or the consolidation or merger or other business
                  combination of the Company with or into any corporation, trust
                  or other entity (or of any corporation, trust or other entity
                  with or into the Company) shall not be deemed to constitute a
                  liquidation, dissolution or winding-up of the Company.

                  Section 5. Optional Redemption.

                        (a) Right of Optional Redemption. The Series E Preferred
                  Shares may not be redeemed prior to December 9, 2004. On or
                  after such date, the Company shall have the right to redeem
                  the Series E Preferred Shares, in whole or in part, at any
                  time or from time to time, upon not less than thirty (30) nor
                  more than sixty (60) days' written notice, at a redemption
                  price, payable in cash, equal to $50 per share of Series E
                  Preferred Shares plus accumulated and unpaid distributions,
                  whether or not declared, to the date of redemption. If fewer
                  than all of the outstanding Series E Preferred Shares are to
                  be redeemed, the Series E Preferred Shares to be redeemed
                  shall be selected pro rata (as nearly as practicable without
                  creating fractional shares).

                        (b) Limitation on Redemption. The Company may not redeem
                  fewer than all of the outstanding shares of Series E Preferred
                  Shares unless all accumulated and unpaid distributions have
                  been paid on all outstanding Series E Preferred Shares for all
                  quarterly distribution periods terminating on or prior to the
                  date of redemption.

                        (c) Procedures for Redemption.

                              (i) Notice of redemption will be (i) faxed, and
                        (ii) mailed by the Company, postage prepaid, not less
                        than thirty (30) nor more than sixty (60) days prior to
                        the redemption date, addressed to the respective holders
                        of record of the Series E
<PAGE>

                        Preferred Shares to be redeemed at their respective
                        addresses as they appear on the transfer records of the
                        Company. No failure to give or defect in such notice
                        shall affect the validity of the proceedings for the
                        redemption of any Series E Preferred Shares except as to
                        the holder to whom such notice was defective or not
                        given. In addition to any information required by law or
                        by the applicable rules of any exchange upon which the
                        Series E Preferred Shares may be listed or admitted to
                        trading, each such notice shall state: (i) the
                        redemption date, (ii) the redemption price, (iii) the
                        number of Series E Preferred Shares to be redeemed, (iv)
                        the place or places where such Series E Preferred Shares
                        are to be surrendered for payment of the redemption
                        price, (v) that distributions on the Series E Preferred
                        Shares to be redeemed will cease to accumulate on such
                        redemption date and (vi) that payment of the redemption
                        price and any accumulated and unpaid distributions will
                        be made upon presentation and surrender of such Series E
                        Preferred Shares. If fewer than all of the Series E
                        Preferred Shares held by any holder are to be redeemed,
                        the notice mailed to such holder shall also specify the
                        number of Series E Preferred Shares held by such holder
                        to be redeemed.

                              (ii) If the Company gives a notice of redemption
                        in respect of Series E Preferred Shares (which notice
                        will be irrevocable) then, by 12:00 noon, New York City
                        time, on the redemption date, the Company will deposit
                        irrevocably in trust for the benefit of the holders of
                        the Series E Preferred Shares being redeemed, funds
                        sufficient to pay the applicable redemption price, plus
                        any accumulated and unpaid distributions, whether or not
                        declared, if any, on such shares to the date fixed for
                        redemption, without interest, and will give irrevocable
                        instructions and authority to pay such redemption price
                        and any accumulated and unpaid distributions, whether or
                        not declared, if any, on such shares to the holders of
                        the Series E Preferred Shares upon surrender of the
                        certificates for the Series E Preferred Shares by such
                        holders at the place designated in the notice of
                        redemption. If fewer than all Series E Preferred Shares
                        evidenced by any certificate are being redeemed, a new
                        certificate shall be issued upon surrender of the
                        certificate evidencing all Series E Preferred Shares,
                        evidencing the unredeemed Series E Preferred Shares
                        without cost to the holder thereof. On and after the
                        date of redemption, distributions will cease to
                        accumulate on the Series E Preferred Shares or portions
                        thereof called for redemption, unless the Company
                        defaults in the payment thereof If any date fixed for
                        redemption of Series E Preferred Shares is not a
                        Business Day, then payment of the redemption price
                        payable on such date will be
<PAGE>

                        made on the next succeeding day that is a Business Day
                        (and without any interest or other payment in respect of
                        any such delay) except that, if such Business Day falls
                        in the next calendar year, such payment will be made on
                        the immediately preceding Business Day, in each case
                        with the same force and effect as if made on such date
                        fixed for redemption. If payment of the redemption price
                        or any accumulated or unpaid distributions in respect of
                        the Series E Preferred Shares is improperly withheld or
                        refused and not paid by the Company, distributions on
                        such Series E Preferred Shares will continue to
                        accumulate from the original redemption date to the date
                        of payment, in which case the actual payment date will
                        be considered the date fixed for redemption for purposes
                        of calculating the applicable redemption price and any
                        accumulated and unpaid distributions.

                        (e) Status of Redeemed Shares. Any Series E Preferred
                  Shares that shall at any time have been redeemed shall after
                  such redemption, have the status of authorized but unissued
                  Shares, without designation as to class or series until such
                  shares are once more designated as part of a particular class
                  or series by the Board.

                  Section 6. Voting Rights.

                        (a) General. Holders of the Series E Preferred Shares
                  will not have any voting rights, except as set forth below.

                        (b) Right to Elect Trustees.

                              (i) If at any time full distributions shall not
                        have been timely made on any Series E Preferred Shares
                        with respect to any six (6) prior quarterly distribution
                        periods, whether or not consecutive, (a "Preferred
                        Distribution Default"), the holders of such Series E
                        Preferred Shares, voting together as a single class with
                        the holders of each class or series of Series E Parity

                        conferred and are exercisable, will have the right to
                        elect two additional Trustees to serve on the Company's
                        Board (the "Series E Preferred Shares Trustees") at a
                        special meeting called by the holders of record of at
                        least 10% of the outstanding Series E Preferred Shares

                        Shares or at the next annual meeting of Shareholders,

                              (ii) At any time when such voting rights shall
                        have vested, a proper officer of the Company shall call
                        or cause to be called, upon written request of holders

                        third Business Day preceding the day on which such
                        notice is mailed. At any such special meeting, all of
                        the holders of the Series E Parity Securities, by

                        without regard to series will be entitled to elect two
                        Trustees on the basis of one vote per $25.00 of
                        liquidation preference to which such Series E Parity
                        Securities are entitled by their terms (excluding
                        amounts in respect of accumulated and unpaid dividends)
                        and not cumulatively. The holder or holders of one-third
                        of the Series E Parity Securities then outstanding,
                        present in person or by proxy, will constitute a quorum
                        for the election of the Series F Preferred Shares
                        Trustees except as otherwise provided by law. Notice of
                        all meetings at which holders of the Series E Preferred
                        Shares shall be entitled to vote will be given to such
                        holders at their addresses as they appear in the
                        transfer records. At any such meeting or adjournment
                        thereof in the absence of a quorum, subject to the
                        provisions of any applicable law, a majority of the
                        holders of the Series F Parity Securities present in
                        person or by proxy shall have the power to adjourn the
                        meeting for the election of the Series E Preferred
                        Shares Trustees, without notice other than an
                        announcement at the meeting, until a quorum is present.
                        If a Series E Preferred Distribution Default shall
                        terminate after the notice of a special meeting has been
                        given but before such special meeting has been held, the
                        Company shall, as soon as practicable after such
                        termination, mail or cause to be mailed notice of such
                        termination to holders of the Series E Preferred Shares
                        that would have been entitled to vote at such special
                        meeting.

                              (iii) If and when all accumulated distributions
                        and the distributions for the current distribution
                        period on the Series E Preferred Shares shall have been
                        paid in full or a sum sufficient for
<PAGE>

                        such payment is irrevocably deposited in trust for
                        payment, the holders of the Series E Preferred Shares
                        shall be divested of the voting rights set forth in this
                        Section 6(b) herein (subject to revesting in the event
                        of each and every Series E Preferred Distribution
                        Default) and, if all distributions in arrears and the
                        distributions for the current distribution period have
                        been paid in full or set aside for payment in full on
                        all other classes or series of Series E Parity Preferred
                        Shares upon which like voting rights have been conferred
                        and are exercisable, the term and office of each Series
                        E Preferred Shares Trustee so elected shall terminate.
                        Any Series E Preferred Shares Trustee may be removed at
                        any time with or without cause by the vote of, and shall
                        not be removed otherwise than by the vote of, the
                        holders of record of a majority of the outstanding
                        Series E Parity Securities when they have the voting
                        rights set forth in this Section 6(b). So long as a
                        Series E Preferred Distribution Default shall continue,
                        any vacancy in the office of a Series E Preferred Shares
                        Trustee may be filled by written consent of the Series E
                        Preferred Shares Trustee remaining in office, or if none
                        remains in office, by a vote of the holders of record of
                        a majority of the outstanding Series E Parity Securities
                        when they have the voting rights set forth in this
                        Section 6(b). The Series E Preferred Shares Trustees
                        shall each be entitled to one vote per trustee on any
                        matter.

                        (c) Certain Voting Rights. So long as any Series E
                  Preferred Shares remain outstanding, the Company shall not,
                  without the affirmative vote of the holders of at least
                  two-thirds of the Series E Preferred Shares outstanding at the
                  time (i) designate or create, or increase the authorized or
                  issued amount of, any class or series of shares ranking senior
                  to the Series E Preferred Shares with respect to payment of
                  distributions or rights upon liquidation, dissolution or
                  winding-up of the Company or reclassify any authorized shares
                  of the Company into any such shares, or create, authorize or
                  issue any obligations or security convertible into or
                  evidencing the right to purchase any such shares, (ii)
                  designate or create, or increase the authorized or issued
                  amount of, any Series F Parity Preferred Shares or reclassify
                  any authorized shares of the Company into any such shares, or
                  create, authorize or issue any obligations or security
                  convertible into or evidencing the right to purchase any such
                  shares, but only to the extent such Series E Parity Preferred
                  Shares are issued to an affiliate of the Company, or (iii)
                  either (A) consolidate, merge into or with, or convey,
                  transfer or lease its assets substantially as an entirety, to
                  any corporation or other entity, or (B) amend, alter or repeal
                  the provisions of the Company's Charter (including these
                  Articles Supplementary) or By-laws, whether by merger,
                  consolidation or otherwise, in each case that would materially
                  and adversely affect the powers, special rights,
<PAGE>

                  preferences, privileges or voting power of the Series E
                  Preferred Shares or the holders thereof; provided, however,
                  that with respect to the occurrence of a merger, consolidation
                  or a sale or lease of all or substantially all of the
                  Company's assets as an entirety, so long as (a) the Company is
                  the surviving entity and the Series E Preferred Shares remain
                  outstanding with the terms thereof unchanged, or (b) the
                  resulting, surviving or transferee entity is a corporation
                  organized under the laws of any state and substitutes the
                  Series E Preferred Shares for other preferred Shares having
                  substantially the same terms and same rights as the Series E
                  Preferred Shares, including with respect to distributions,
                  voting rights and rights upon liquidation, dissolution or
                  winding-up of the Company, then the occurrence of any such
                  event shall not be deemed to materially and adversely affect
                  such rights, privileges or voting powers of the holders of the
                  Series E Preferred Shares and no vote of the Series E
                  Preferred Shares shall be required; and provided further that
                  any increase in the amount of authorized Shares or the
                  creation or issuance of any other class or series of Shares,
                  or any increase in an amount of authorized shares of each
                  class or series, in each case ranking either (a) junior to the
                  Series E Preferred Shares with respect to payment of
                  distributions and the distribution of assets upon liquidation,
                  dissolution or winding-up of the Company, or (b) on a parity
                  with the Series E Preferred Shares with respect to payment of
                  distributions or the distribution of assets upon liquidation,
                  dissolution or winding-up of the Company to the extent such
                  Shares are not issued to an affiliate of the Company, shall
                  not be deemed to materially and adversely affect such rights,
                  preferences, privileges or voting powers and no vote of the
                  Series E Preferred Shares shall be required.

                  Section 7. Transfer Restrictions. The Series E Preferred
            Shares shall be subject to the provisions of Article 3 of the
            Charter; provided, however, in no event shall the Ownership Limit
            with respect to the Series E Preferred Shares (as defined in the
            Charter) be decreased pursuant to Section 10 of Article 3 of the
            Charter or otherwise (other than a decrease as a result of a
            retroactive change in existing law that would require a decrease to
            retain real estate investment trust status under the Internal
            Revenue Code of 1986, as amended).

                  Section 8. No Conversion Rights. The holders of the Series E
            Preferred Shares shall not have any rights to convert such shares
            into shares of any other class or series of Shares or into any other
            securities of, or interest in, the Company.

                  Section 9. No Sinking Fund. No sinking fund shall be
            established for the retirement or redemption of Series E Preferred
            Shares.

                  Section 10. No Preemptive Rights. No holder of the Series E
            Preferred Shares of the Company shall, as such holder, have any
            preemptive rights
<PAGE>

            to purchase or subscribe for additional Shares of the Company or any
            other security of the Company which it may issue or sell.

            THIRD: The Series E Preferred Shares have been classified and
      designated by the Board under the authority contained in the Charter.

            FOURTH: These Articles Supplementary have been approved by the Board

                                 FIFTH AMENDMENT
                                       TO
                           SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                        CABOT INDUSTRIAL PROPERTIES, L.P.

      THIS FIFTH AMENDMENT TO SECOND AMENDED AND RESTATED AGREEMENT OF LIMITED
PARTNERSHIP (this "Amendment") dated as of December 22, 1999, is entered into by
CABOT INDUSTRIAL TRUST, a Maryland real estate investment trust, as general
partner (the "General Partner") of CABOT INDUSTRIAL PROPERTIES, L.P. (the
"Partnership"), for itself and on behalf of the limited partners of the
Partnership, and SALOMON SMITH BARNEY TAX ADVANTAGED EXCHANGE FUND II, LLC, a
Delaware limited liability company ("Contributor").

      WHEREAS, Section 4.2(a) of the Second Amended and Restated Agreement of
Limited Partnership of the Partnership (the "Partnership Agreement") authorizes
the General Partner to cause the Partnership to issue additional Partnership
Units in one or more classes or series, with such designations, preferences and
relative, participating, optional or other special rights, powers and duties as
shall be determined by the General Partner, subject to the provisions of such
section; and

      WHEREAS, pursuant to the authority granted to the General Partner pursuant
to Sections 4.2(a) and 14.1(b) of the Partnership Agreement, the General Partner
desires to amend the Partnership Agreement (i) to establish a new class of
Partnership Units, the Series F Preferred Units (as hereinafter defined), and to
set forth the designations, rights, powers, preferences and duties of such
Series F Preferred Units, (ii) to issue the Series F Preferred Units to
Contributor and admit Contributor as an Additional Limited Partner and (iii) to
make certain other changes to the Partnership Agreement.

NOW, THEREFORE, in consideration of good and valuable consideration, the receipt
and sufficiency of which hereby are acknowledged, the General Partner hereby
amends the Partnership Agreement as follows:

            Section 1. Definitions. For purposes of this Amendment, the term
"Parity Preferred Units" shall be used to refer to any class or series of
Partnership Interests of the Partnership now or hereafter authorized, issued or
outstanding expressly designated by the Partnership to rank on a parity with
Series F Preferred Units with respect to distributions and rights upon voluntary
or involuntary liquidation, winding-up or dissolution of the Partnership. The
term "Priority Return" shall mean, an amount equal to 8.5% per annum, determined
on the basis of a 360 day year of twelve 30 day months, cumulative to the extent
not distributed for any given distribution period pursuant to Section 5.1 of the
Partnership Agreement, of the stated value of $25 per Series F Preferred Unit,
commencing on the date of issuance of such Series F Preferred Unit. The term
"Subsidiary" shall mean with respect to any person, any corporation,
partnership, limited liability company, joint venture or other entity of which a
majority of(i) voting power of the voting equity securities or (ii) the
outstanding equity interests, is owned, directly or indirectly, by such person.
The term "PTP" shall mean a "publicly traded
<PAGE>

partnership" within the meaning of Section 7704 of the Code. Capitalized terms
used herein and not otherwise defined herein shall have the meanings ascribed to
them in the Partnership Agreement.

      Section 2. Designation and Number. A series of Partnership Units in the
Partnership designated as the "8.5% Series F Cumulative Redeemable Preferred
Units" (the "Series F Preferred Units") is hereby established. The number of
Series F Preferred Units shall be 1,800,000.

      Section 3. Distributions. (a) Payment of Distributions. Subject to the
rights of holders of Parity Preferred Units as to the payment of distributions,
pursuant to Section 5.1 of the Partnership Agreement, holders of Series F
Preferred Units shall be entitled to receive, when, as and if declared by the
Partnership acting through the General Partner, out of Available Cash,
cumulative preferential cash distributions at the rate per annum of 8.5% of the
original Capital Contribution per Series F Preferred Unit. Such distributions
shall be cumulative, shall accrue from the original date of issuance and will be
payable (i) quarterly in arrears, on March 25, June 25, September 25 and
December 25 of each year commencing on March 25, 2000 and, (ii), in the event of
(A) an exchange of Series F Preferred Units into Series F Preferred Shares, or
(B) a redemption of Series F Preferred Units, on the exchange date or redemption
date, as applicable (each a "Preferred Unit Distribution Payment Date"). The
amount of the distribution payable for any period will be computed on the basis
of a 360-day year of twelve 30-day months and for any period shorter than a full
quarterly period for which distributions are computed, the amount of the
distribution payable will be computed on the basis of the actual number of days
elapsed in such period. If any date on which distributions are to be made on the
Series F Preferred Units is not a Business Day (as defined herein), then payment
of the distribution to be made on such date will be made on the next succeeding
day that is a Business Day (and without any interest or other payment in respect
of any such delay) except that, if such Business Day is in the next succeeding
calendar year, such payment shall be made on the immediately preceding Business
Day, in each case with the same force and effect as if made on such date.
Distributions on the Series F Preferred Units will be made to the holders of
record of the Series F Preferred Units on the relevant record dates to be fixed
by the Partnership acting through the General Partner, which record dates shall
in no event exceed fifteen (15) Business Days prior to the relevant Preferred
Unit Distribution Payment Date (the "Preferred Unit Partnership Record Date").

      The term "Business Day" shall mean each day other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulations or executive order to close.

            (b) Distributions Cumulative. Distributions on the Series F
Preferred Units will accrue whether or not the terms and provisions of any
agreement of the Partnership, including any agreement relating to its
indebtedness, at any time prohibit the current payment of distributions, whether
or not the Partnership has earnings, whether or not there are funds legally
available for the payment of such distributions and whether or not such
distributions are authorized. Accrued but unpaid distributions on the Series F
Preferred Units will accumulate as of the Preferred Unit Distribution Payment
Date on which they first become payable. Distributions on account of arrears for
any past distribution periods may be declared and paid at any time, without
reference to a regular Preferred Unit Distribution Payment Date to holders of
<PAGE>

record of the Series F Preferred Units on the record date fixed by the
Partnership acting through the General Partner, which date shall not exceed
fifteen (15) Business Days prior to the payment date. Accumulated and unpaid
distributions will not bear interest.

            (c) Priority as to Distributions. (i) So long as any Series F
Preferred Units are outstanding, no distribution of cash or other property shall
be authorized, declared, paid or set apart for payment on or with respect to any
class or series of Partnership Interests of the Partnership ranking junior as to
the payment of distributions or rights upon a voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership to the Series F
Preferred Units (collectively, "Junior Units"), nor shall any cash or other
property be set aside for or applied to the purchase, redemption or other
acquisition for consideration of any Series F Preferred Units, any Parity
Preferred Units or any Junior Units, unless, in each case, all distributions
accumulated on all Series F Preferred Units and all classes and series of
outstanding Parity Preferred Units have been paid in full. The foregoing
sentence will not prohibit (a) distributions payable solely in Junior Units, (b)
the conversion of Junior Units or Parity Preferred Units into Partnership Units
ranking junior to the Series F Preferred Units as to distributions and upon
liquidation, winding-up or dissolution or (c) the redemption of Partnership
Interests corresponding to any Series F Preferred Shares (as hereinafter
defined), Parity Preferred Shares (as such term is defined in the Declaration of
Trust of the General Partner, as supplemented (the "Charter")), or Junior Shares
(as such term is defined in the Charter) to be purchased by the General Partner
pursuant to Article 3 of the Charter to preserve the General Partner's status as
a real estate investment trust, provided that such redemption shall be upon the
same terms as the corresponding purchase pursuant to Article 3 of the Charter.

      (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series F Preferred Units, all distributions authorized and
declared on the Series F Preferred Units and all classes or series of
outstanding Parity Preferred Units shall be authorized and declared so that the
amount of distributions authorized and declared per Series F Preferred Unit and
such other classes or series of Parity Preferred Units shall in all cases bear
to each other the same ratio that accrued distributions per Series F Preferred
Unit and such other classes or series of Parity Preferred Units (which shall not
include any accumulation in respect of unpaid distributions for prior
distribution periods if such class or series of Parity Preferred Units do not
have cumulative distribution rights) bear to each other.

            (d) No Further Rights. Holders of Series F Preferred Units shall not
be entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

      Section 4. Liquidation Proceeds. (a) Upon voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, distributions on the
Series F Preferred Units shall be made in accordance with Section 13.2 of the
Partnership Agreement.

            (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Partnership, stating the payment
date or dates when, and the place or places where, the amounts distributable in
such circumstances shall be payable, shall be given by (i) fax and (ii) by first
class mail, postage pre-paid, not less than thirty (30) and not more than sixty
(60) days prior to the payment date stated therein, to each record holder of the


                                       3
<PAGE>

Series F Preferred Units at the respective addresses of such holders as the same
shall appear on the transfer records of the Partnership.

            (c) No Further Rights. After payment of the full amount of the
liquidating distributions to which they are entitled, the holders of Series F
Preferred Units will have no right or claim to any of the remaining assets of
the Partnership.

            (d) Consolidation, Merger or Certain Other Transactions. The
voluntary sale, conveyance, lease, exchange or transfer (for cash, shares of
stock, securities or other consideration) of all or substantially all of the
property or assets of the General Partner to, or the consolidation or merger or
other business combination of the Partnership with or into, any corporation,
trust, partnership, limited liability company or other entity (or of any
corporation, trust, partnership, limited liability company or other entity with
or into the Partnership) shall not be deemed to constitute a liquidation,
dissolution or winding-up of the Partnership.

      Section 5. Optional Redemption. (a) Right of Optional Redemption. The
Series F Preferred Units may not be redeemed prior to the fifth (5th)
anniversary of the issuance date. On or after such date, the Partnership shall
have the right to redeem the Series F Preferred Units, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to the Capital Account balance of the holders of Series F Preferred Units (the
"Redemption Price"); provided, however, that no redemption pursuant to this
Section 5 will be permitted if the Redemption Price does not equal or exceed the
original Capital Contribution of such holder plus the cumulative Priority
Return, whether or not declared, to the redemption date to the extent not
previously distributed or distributed pursuant to Section 3(a). If fewer than
all of the outstanding Series F Preferred Units are to be redeemed, the Series F
Preferred Units to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional units).

            (b) Limitation on Redemption. The Partnership may not redeem fewer
than all of the outstanding Series F Preferred Units unless all accumulated and
unpaid distributions have been paid on all Series F Preferred Units for all
quarterly distribution periods terminating on or prior to the date of
redemption.

            (c) Procedures for Redemption. (i) Notice of redemption will be (A)
faxed, and (B) mailed by the Partnership, by certified mail, postage prepaid,
not less than thirty (30) nor more than sixty (60) days prior to the redemption
date, addressed to the respective holders of record of the Series F Preferred
Units at their respective addresses as they appear on the records of the
Partnership. No failure to give or defect in such notice shall affect the
validity of the proceedings for the redemption of any Series F Preferred Units
except as to the holder to whom such notice was defective or not given. In
addition to any information required by law, each such notice shall state: (1)
the redemption date, (2) the Redemption Price, (3) the aggregate number of
Series F Preferred Units to be redeemed and if fewer than all of the outstanding
Series F Preferred Units are to be redeemed, the number of Series F Preferred
Units to be redeemed held by such holder, which number shall equal such holder's
pro rata share (based on the percentage of the aggregate number of outstanding
Series F Preferred Units the total number of Series F Preferred Units held by
such holder represents) of the aggregate number of Series F Preferred Units to
be redeemed, (4) the place or places where such Series F Preferred Units are to
be surrendered for payment of the Redemption Price, (5) that distributions on
the Series F Preferred Units to be redeemed will cease to accumulate on such
redemption date and (6) that


                                       4
<PAGE>

payment of the Redemption Price will be made upon presentation and surrender of
such Series F Preferred Units.

      (ii) If the Partnership gives a notice of redemption in respect of Series
F Preferred Units (which notice will be irrevocable) then, by 12:00 noon, New
York City time, on the redemption date, the Partnership will deposit irrevocably
in trust for the benefit of the Series F Preferred Units being redeemed funds
sufficient to pay the applicable Redemption Price and will give irrevocable
instructions and authority to pay such Redemption Price to the holders of the
Series F Preferred Units upon surrender of the Series F Preferred Units by such
holders at the place designated in the notice of redemption. If the Series F
Preferred Units are evidenced by a certificate and if fewer than all Series F
Preferred Units evidenced by any certificate are being redeemed, a new
certificate shall be issued upon surrender of the certificate evidencing all
Series F Preferred Units, evidencing the unredeemed Series F Preferred Units
without cost to the holder thereof. On and after the date of redemption,
distributions will cease to accumulate on the Series F Preferred Units or
portions thereof called for redemption, unless the Partnership defaults in the
payment thereof. If any date fixed for redemption of Series F Preferred Units is
not a Business Day, then payment of the Redemption Price payable on such date
will be made on the next succeeding day that is a Business Day (and without any
interest or other payment in respect of any such delay) except that, if such
Business Day falls in the next calendar year, such payment will be made on the
immediately preceding Business Day, in each case with the same force and effect
as if made on such date fixed for redemption. If payment of the Redemption Price
is improperly withheld or refused and not paid by the Partnership, distributions
on such Series F Preferred Units will continue to accumulate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
applicable Redemption Price.

      Section 6. Voting Rights. (a) General. Holders of the Series F Preferred
Units will not have any voting rights or right to consent to any matter
requiring the consent or approval of the Limited Partners, except as set forth
in the Partnership Agreement and except as set forth below. In the event of a
conflict between the terms of this Section 6 and any other terms of this
Amendment, the terms of this Section 6 shall control.

            (b) Certain Voting Rights. So long as any Series F Preferred Units
remain outstanding, the Partnership shall not, without the affirmative vote of
the holders of at least two-thirds of the Series F Preferred Units outstanding
at the time (i) authorize or create, or increase the authorized or issued amount
of, any class or series of Partnership Interests senior to the Series F
Preferred Units with respect to payment of distributions or rights upon
liquidation, dissolution or winding-up of the Partnership or reclassify any
Partnership Interests of the Partnership into any such senior Partnership
Interests, or create, authorize or issue any obligations or security convertible
into or evidencing the right to purchase any such senior Partnership Interests,
(ii) authorize or create, or increase the authorized or issued amount of any
Parity Preferred Units or reclassify any Partnership Interest into any such
Partnership Interest or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such Partnership
Interests but only to the extent such Parity Preferred Units are issued to an
Affiliate of the Partnership, other than the General Partner to the extent the
issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates of the
Partnership (or to Affiliates purchasing the preferred stock


                                       5
<PAGE>

on the same terms as non-affiliated purchasers) or (iii) either (A) consolidate,
merge into or with, or convey, transfer or lease all or substantially all of its
assets to, any corporation or other entity or (B) amend, alter or repeal the
provisions of the Partnership Agreement (including, without limitation, this
Amendment) whether by merger, consolidation or otherwise, that would materially
and adversely affect the powers, special rights, preferences, privileges or
voting power of the Series F Preferred Units or the holders thereof, provided,
however, that with respect to the occurrence of a merger, consolidation or a
sale or lease of all or substantially all of the Partnership's assets as an
entirety, so long as (1) the Partnership is the surviving entity and the Series
F Preferred Units remain outstanding with the terms thereof unchanged, or (2)
the resulting, surviving or transferee entity is a partnership, limited
liability company or other pass-through entity organized under the laws of any
state and substitutes the Series F Preferred Units for other interests in such
entity having substantially the same terms and rights as the Series F Preferred
Units, including with respect to distributions, redemptions, transfers, voting
rights and rights upon liquidation, dissolution or winding-up of the
Partnership, then the occurrence of any such event shall not be deemed to
materially and adversely affect such rights, privileges or voting powers of the
holders of the Series F Preferred Units and no vote of the Series F Preferred
Units shall be required in such case; and provided further that any increase in
the amount of Partnership Interests or the creation or issuance of any other
class or series of Partnership Interests, in each case ranking (y) junior to the
Series F Preferred Units with respect to payment of distributions or the
distribution of assets upon liquidation, dissolution or winding-up of the
Partnership, or (z) on a parity with the Series F Preferred Units with respect
to payment of distributions and the distribution of assets upon liquidation,
dissolution or winding-up of the Partnership to the extent such Partnership
Interests are not issued to an Affiliate, other than the General Partner to the
extent the issuance of such interests was to allow the General Partner to issue
corresponding preferred stock to persons who are not Affiliates, shall not be
deemed to materially and adversely affect such rights, preferences, privileges
or voting powers and no vote of the Series F Preferred Units shall be required
in such case.

      Section 7. Transfer Restrictions. The Series F Preferred Units shall be
subject to the provisions of Article XI of the Partnership Agreement, provided,
however, that (i) the General Partner shall act reasonably in exercising its
discretion pursuant to the provisions of Section 11.4(a)(ii) to transferees of
Series F Preferred Units, (ii) the provisions of Clause B of Section 11.3(d)
shall not be applicable to holders of Series F Preferred Units if at the time of
such transfer, the Partnership already has 100 Partners; (iii) if only a portion
of the Series F Preferred Units shall be transferred, the transferee of such
transferred Series F Preferred Units shall, subject to the provisions of Section
11.4, be substituted as a Limited Partner in place of the transferring holders
only as to the Series F Preferred Units so transferred; and (iv) the provisions
of Sections 11.6(c) and 11.6(d) shall not be applicable to any transfer of
Series F Preferred Units; and provided further that "transfer" when used in
Article XI shall not be deemed to include any exchange pursuant to Section 8
below.

      Section 8. Exchange Rights. (a) Right to Exchange. (i) Series F Preferred
Units will be exchangeable in whole or in part at anytime on or after the tenth
(10th) anniversary of the date of issuance, at the option of the holders
thereof, for authorized but previously unissued shares of 8.5% Series F
Cumulative Redeemable Preferred Shares of the General Partner (the "Series F
Preferred Shares") at an exchange rate of one Series F Preferred Share for one
Series F


                                       6
<PAGE>

Preferred Unit, subject to adjustment as described below (the "Exchange Price"),
provided that the Series F Preferred Units will become exchangeable at any time,
in whole or in part, at the option of the holders of Series F Units, for Series
F Preferred Shares if (y) at any time full distributions shall not have been
timely made on any Series F Preferred Unit with respect to six (6) prior
quarterly distribution periods, whether or not consecutive; provided, however,
that a distribution in respect of Series F Preferred Units shall be considered
timely made if made within two (2) Business Days after the applicable Preferred
Unit Distribution Payment Date if at the time of such late payment there shall
not be any prior quarterly distribution periods in respect of which full
distributions were not timely made or (z) upon receipt by a holder or holders of
Series F Preferred Units of (1) a notice from the General Partner that the
General Partner or a Subsidiary of the General Partner has taken the position
that the Partnership is, or upon the occurrence of a defined event in the
immediate future will be, a PTP and (2) an opinion rendered by an outside
nationally recognized independent counsel familiar with such matters addressed
to a holder or holders of Series F Preferred Units, that the Partnership is or
likely is, or upon the occurrence of a defined event in the immediate future
will be or likely will be, a PTP. In addition, the Series F Preferred Units may
be exchanged for Series F Preferred Shares, in whole or in part, at the option
of any holder prior to the tenth (10th) anniversary of the issuance date and
after the third (3rd) anniversary thereof if such holder of a Series F Preferred
Units shall deliver to the General Partner either (i) a private letter ruling
addressed to such holder of Series F Preferred Units or (ii) an opinion of
independent counsel reasonably acceptable to the General Partner based on the
enactment of a statute, temporary or final Treasury Regulations or the
publication of a Revenue Ruling, in either case to the effect that an exchange
of the Series F Preferred Units at such earlier time would not cause the Series
F Preferred Units to be considered "stock or securities" within the meaning of
Section 351(e) of the Code for purposes of determining whether the holder of
such Series F Preferred Units is an "investment company" under Section 721(b) of
the Code if an exchange is permitted at such earlier date. Furthermore, all the
Series F Preferred Units, held by any holder thereof which is a real estate
investment trust within the meaning of Sections 856 through 859 of the Code for
Series F Preferred Shares may be exchanged in whole but not in part (but only if
the exchange may be accomplished consistently with the ownership limitations set
forth tinder Article 3 of the Charter (taking into account exceptions thereto))
if at any time, (i) the Partnership reasonably determines that the assets and
income of the Partnership for a taxable year after 1999 would not satisfy the
income and assets tests of Section 856 of the Code for such taxable year if the
Partnership were a real estate investment trust within the meaning of the Code
or (ii) any such holder of Series F Preferred Units shall deliver to the
Partnership and the General Partner an opinion of independent counsel reasonably
acceptable to the General Partner to the effect that, based on the assets and
income of the Partnership for a taxable year after 1999, the Partnership would
not satisfy the income assets tests of Section 856 of the Code for such taxable
year if the Partnership were a real estate investment trust within the meaning
of the Code and that such failure would create a meaningful risk that a holder
of the Series F Preferred Units would fail to maintain qualification as a real
estate investment trust.

      (ii) Notwithstanding anything to the contrary set forth in Section 8(a)(i)
hereof, if an Exchange Notice (as defined herein) has been delivered to the
General Partner, then the General Partner may, at its option, elect to redeem or
cause the Partnership to redeem all or a portion of


                                       7
<PAGE>

the outstanding Series F Preferred Units for cash in an amount equal to the
original Capital Contribution per Series F Preferred Unit and all accrued and
unpaid distributions thereon to the date of redemption. The General Partner may
exercise its option to redeem the Series F Preferred Units for cash pursuant to
this Section 8(a)(ii) hereof by giving each holder of record of Series F
Preferred Units notice of its election to redeem for cash, within ten (10)
Business Days after receipt of the Exchange Notice, by (y) fax, and (z)
registered mail, postage paid, at the address of each holder as it may appear on
the records of the Partnership stating (A) the redemption date, which shall be
no later than sixty (60) days following the receipt of the Exchange Notice, (B)
the redemption price, (C) the place or places where the Series F Preferred Units
are to be surrendered for payment of the redemption price, (D) that
distributions on the Series F Preferred Units will cease to accrue on such
redemption date; (E) that payment of the redemption price will be made upon
presentation and surrender of the Series F Preferred Units and (F) the aggregate
number of Series F Preferred Units to be redeemed, and if fewer than all of the
outstanding Series F Preferred Units are to be redeemed, the number of Series F
Preferred Units to be redeemed held by such holder, which number shall equal
such holder's pro-rata share (based on the percentage of the aggregate number of
outstanding Series F Preferred Units the total number of Series F Preferred
Units held by such holder represents) of the aggregate number of Series F
Preferred Units being redeemed.

      (iii) In the event an exchange of all or a portion of Series F Preferred
Units pursuant to Section 8(a)(i) hereof would violate the provisions on
ownership limitation of the General Partner set forth in Article 3 of the
Charter with respect to the Series F Preferred Shares, the General Partner shall
give written notice thereof to each holder of record of Series F Preferred
Units, within ten (10) Business Days following receipt of the Exchange Notice,
by (y) fax, and (z) registered mail, postage prepaid, at the address of each
such holder set forth in the records of the Partnership. In such event, each
holder of Series F Preferred Units shall be entitled to exchange, pursuant to
the provision of Section 8(b) a number of Series F Preferred Units which would
comply with the provisions on the ownership limitation of the General Partner
set forth in such Article 3 of the Charter and any Series F Preferred Units not
so exchanged (the "Excess Units") shall be redeemed by the Partnership for cash
in an amount equal to the original Capital Contribution per Excess Unit, plus
any accrued and unpaid distributions thereon, whether or not declared, to the
date of redemption. The written notice of the General Partner shall state (A)
the number of Excess Units held by such holder, (B) the redemption price of the
Excess Units, (C) the date on which such Excess Units shall be redeemed, which
date shall be no later than sixty (60) days following the receipt of the
Exchange Notice, (D) the place or places where such Excess Units are to be
surrendered for payment of the Redemption Price, (E) that distributions on the
Excess Units will cease to accrue on such redemption date, and (F) that payment
of the redemption price will be made upon presentation and surrender of such
Excess Units. In the event an exchange would result in Excess Units, as a
condition to such exchange, each holder of such units agrees to provide
representations and covenants reasonably requested by the General Partner
relating to (1) the widely held nature of the interests in such holder,
sufficient to assure the General Partner that the holder's ownership of stock of
the General Partner (without regard to the limits described above) will not
cause any individual to Beneficially Own in excess of the Ownership Limit (all
as defined in the General Partner's Charter); and (2) to the extent such holder
can so represent and covenant without obtaining information from its owners, the
holder's


                                       8
<PAGE>

ownership of tenants of the Partnership and its affiliates.

      (iv) The redemption of Series F Preferred Units described in Section
8(a)(ii) and (iii) shall be subject to the provisions of Sections 5(b) and
5(c)(ii); provided, however, that the term "Redemption Price" in such section
shall be read to mean the original Capital Contribution per Series F Preferred
Unit being redeemed plus all accrued and unpaid distributions to the redemption
date.

            (b) Procedure for Exchange. (i) Any exchange pursuant to this
Amendment shall be exercised pursuant to a notice of exchange (the "Exchange
Notice") delivered to the General Partner by the holder who is exercising such
exchange right, by (A) fax and (B) by certified mail postage prepaid. The
exchange of Series F Preferred Units, or a specified portion thereof, may be
effected after the fifth (5th) Business Day following receipt by the General
Partner of the Exchange Notice by delivering certificates, if any, representing
such Series F Preferred Units to be exchanged together with, if applicable,
written notice of exchange and a proper assignment of such Series F Preferred
Units to the office of the General Partner maintained for such purpose.
Currently, such office is Two Center Plaza, Suite 200, Boston, Massachusetts
02108. Each exchange will be deemed to have been effected immediately prior to
the close of business on the date on which such Series F Preferred Units to be
exchanged (together with all required documentation) shall have been surrendered
and notice shall have been received by the General Partner as aforesaid and the
Exchange Price shall have been paid. Any Series F Preferred Shares issued
pursuant to this Section 8 shall be delivered as shares which are duly
authorized, validly issued, fully paid and nonassessable, free of pledge, lien,
encumbrance or restriction other than those provided in the Charter, the Bylaws
of the General Partner, the Securities Act of 1933 and relevant state securities
or blue sky laws.

      (ii) In the event of an exchange of Series F Preferred Units for Series F
Preferred Shares, an amount equal to the accrued and unpaid distributions,
whether or not declared, to the date of exchange on any Series F Preferred Units
tendered for exchange shall (A) accrue on the Series F Preferred Shares into
which such Series F Preferred Units are exchanged, and (B) continue to accrue on
such Series F Preferred Units, which shall remain outstanding following such
exchange, with the General Partner as the holder of such Series F Preferred
Units. Notwithstanding anything to the contrary set forth herein, in no event
shall a holder of a Series F Preferred Unit that was validly exchanged into
Series F Preferred Shares pursuant to this section (other than the General
Partner now holding such Series F Preferred Unit), receive a cash distribution
out of Available Cash of the Partnership, if such holder, after exchange, is
entitled to receive a distribution out of Available Cash with respect to the
Series F Preferred Shares for which such Series F Preferred Unit was exchanged
or redeemed.

            (iii) Fractional shares of Series F Preferred Shares are not to be
issued upon exchange but, in lieu thereof, the General Partner will pay a cash
adjustment based upon the fair market value of the Series F Preferred Shares on
the day prior to the exchange date as determined in good faith by the Board of
Trustees of the General Partner.

            (c) Adjustment of Exchange Price. (i) The Exchange Price is subject
to adjustment upon certain events, including (a) subdivisions, combinations and
reclassifications of the Series F Preferred Shares and (b) distributions to all
holders of Series F Preferred Shares of evidences of indebtedness of the General
Partner or assets (including securities but excluding dividends and
distributions paid out of equity applicable to Series F Preferred Shares).


                                       9
<PAGE>

      (ii) In case the General Partner shall be a party to any transaction
(including, without limitation, a merger, consolidation, statutory share
exchange, tender offer for all or substantially all of the General Partner's
capital stock or sale of all or substantially all of the General Partner's
assets), in each case as a result of which the Series F Preferred Shares will be
converted into the right to receive shares of capital stock, other securities or
other property (including cash or any combination thereof), each Series F
Preferred Unit will thereafter be exchangeable into the kind and amount of
shares of capital stock and other securities and property receivable (including
cash or any combination thereof) upon the consummation of such transaction by a
holder of that number of Series F Preferred Shares or fraction thereof into
which one Series F Preferred Unit was exchangeable immediately prior to such
transaction. The General Partner may not become a party to any such transaction
unless the terms thereof are inconsistent with the foregoing.

      Section 9. No Conversion Rights. (a) The holders of the Series F Preferred
Units shall not have any rights to convert such Partnership Units into any other
class of Partnership Interests or any interest in the Partnership;

      (b) The Series F Preferred Units shall not be subject to the provisions of
Section 4.2(e) of the Partnership Agreement.

      Section 10. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of the Series F Preferred Units.

      Section 11. Admission of Limited Partner; Exhibits to Partnership
Agreement. In accordance with Section 12.2(b), Contributor is hereby admitted as
an Additional Limited Partner. In order to duly reflect the issuance of Series F
Preferred Units provided for herein, the Partnership Agreement will be amended
by deleting Exhibit A attached thereto and substituting Exhibit A attached
hereto therefor.

      Section 12. Reaffirmation. Except as modified herein, all terms and
conditions of the Partnership Agreement shall remain in full force and effect,
which terms and conditions the General Partner hereby ratifies and affirms.

written.

              8.5% SERIES F CUMULATIVE REDEEMABLE PREFERRED SHARES

      Cabot Industrial Trust, a Maryland real estate investment trust (the
"Company"), hereby certifies to the State Department of Assessments and Taxation
of Maryland (the "Department") that:

            FIRST: Under a power contained in Article 2, Section 1 of the
Amended and Restated Declaration of Trust of the Company, filed with, and
accepted for record by, the State Department of Assessments and Taxation of
Maryland (the "SDAT") on January 26, 1998, as supplemented by Articles
Supplementary tiled with, and accepted for record by, the SDAT, respectively, on
July 10. 1998, on April 29, 1999, on September 3, 1999, on September 27, 1999
and on December 9, 1999 and as corrected by that certain Certificate of
Correction filed with, and accepted for record by, the SDAT on October 12, 1999
(as supplemented and corrected, the "Charter"). the Board of Trustees of the
Company, as required by Section 8-203(b) of the Corporations and Associations
Article of the Annotated Code of Maryland, has unanimously adopted resolutions
classifying and designating 1,800,000 unissued shares of beneficial interest as
8.5% Series F Cumulative Redeemable Preferred Shares, par value $0.01 per share,
with the following preferences, conversion and other rights, voting powers,
restrictions, limitations as to dividends and other distributions,
qualifications and terms and conditions of redemption, and other terms and
conditions, which upon any restatement of the Charter shall be made part of
Article 2 of the Charter, with any necessary or appropriate changes to the
enumeration and lettering thereof.

            SECOND:The following is a description of the 8.5% Series F
Cumulative Redeemable Preferred Shares, including the preferences. conversion
and other rights, voting powers, restrictions, limitations as to dividends,
qualifications, and terms and conditions of redemption thereof:

              8.5% SERIES F CUMULATIVE REDEEMABLE PREFERRED SHARES

      SECTION 1. Designation and Number. A series of preferred shares,
designated the "8.5% Series F Cumulative Redeemable Preferred Shares" (the
"Series F Preferred Shares") is hereby established. The number of shares of
Series F Preferred Shares shall be 1,800,000, par value $0.01 per share.

      SECTION 2. Rank. The Series F Preferred Shares shall, with respect to
distributions and rights upon voluntary or involuntary liquidation, winding-up
or dissolution of the Company, rank senior to all classes or series of common
shares and to all classes or series of equity securities of the Company now or
hereafter authorized, issued or outstanding, other than any class or series of
equity securities of the Company expressly designated as ranking on a parity
with or senior to the Series F Preferred Shares as to distributions and rights
upon voluntary or involuntary liquidation, winding-tip or dissolution of the
Company. For purposes of these Articles Supplementary, the term "Parity
Preferred Shares" shall be used to refer to any class or series of equity
securities of the Company now or hereafter authorized, issued or outstanding
expressly designated by the Company to rank on a parity with the Series F
Preferred Shares with respect to distributions and rights upon voluntary or
involuntary liquidation, winding-up or dissolution of the Company, including
specifically the Series B Cumulative Redeemable Preferred Shares, the Series C
Cumulative Redeemable Preferred Shares, the Series D Cumulative Redeemable
Preferred Shares, and the Series E Cumulative Redeemable Preferred Shares. The
term "equity securities" does not include debt securities, which will rank
senior to the Series F Preferred Shares prior to conversion.

      SECTION 3. Distributions.

      (a) Payment of Distributions. Subject to the rights of holders of Parity
Preferred Shares and holders of equity securities ranking senior to the Series F
Preferred Shares as to payment of distributions, holders of Series F Preferred
Shares will be entitled to receive, when, as and if declared by the Board of
Trustees of the Company, out
<PAGE>

of funds legally available for the payment of distributions, cumulative
preferential cash distributions at the rate per annum of 8.5% of the $25
liquidation preference per Series F Preferred Share. Such distributions shall be
cumulative, shall accrue from the original date of issuance and will be payable
(i) quarterly in arrears, on March 25, June 25, September 25 and December 25 of
each year commencing on the first of such dates to occur after the original date
of issuance and, (ii) in the event of a redemption, on the redemption date (each
a "Preferred Shares Distribution Payment Date"). The amount of the distribution
payable for any period will be computed on the basis of a 360-day year of twelve
30-day months and for any period shorter than a full quarterly period for which
distributions are computed, the amount of the distribution payable will be
computed on the basis of the actual number of days elapsed in such period. If
any date on which distributions are to be made on the Series F Preferred Shares
is not a Business Day (as defined herein), then payment of the distribution to
be made on such date will be made on the next succeeding day that is a Business
Day (and without any interest or other payment in respect of any such delay)
except that, if such Business Day is in the next succeeding calendar year, such
payment shall be made on the immediately preceding Business Day, in each case
with the same force and effect as if made on such date. Distributions on the
Series F Preferred Shares will be made to the holders of record of the Series F
Preferred Shares on the relevant record dates, which, unless otherwise provided
by the Company with respect to any distribution, will be fifteen (15) Business
Days prior to the relevant Preferred Shares Distribution Payment Date (each a
"Distribution Record Date"). Notwithstanding anything to the contrary set forth
herein, each Series F Preferred Share shall also continue to accrue all accrued
and unpaid distributions up to the exchange date on any Series F Preferred Unit
(as defined in the Second Amended and Restated Agreement of Limited Partnership
of Cabot Industrial Properties, L.P., dated as of February 4, 1998 (as amended
through the date hereof, the "Partnership Agreement") validly exchanged into
such Series F Preferred Share in accordance with the provisions of such
Partnership Agreement.

      The term "Business Day" shall mean each day, other than a Saturday or a
Sunday, which is not a day on which banking institutions in New York, New York
are authorized or required by law, regulation or executive order to close.

      (b) Limitation on Distributions. No distributions on the Series F
Preferred Shares shall be declared or paid or set apart for payment by the
Company at such time as the terms and provisions of any agreement of the
Company, including any agreement relating to its indebtedness, prohibits such
declaration, payment or setting apart for payment or provides that such
declaration, payment or setting apart for payment would constitute a breach
thereof or a default thereunder, or if such declaration, payment or setting
apart for payment shall be restricted or prohibited by law.

      (c) Distributions Cumulative. Notwithstanding the foregoing, distributions
on the Series F Preferred Shares will accrue whether or not the terms and
provisions set forth in Section 3(b) hereof at any time prohibit the current
payment of distributions, whether or not the Company has earnings, whether or
not there are funds legally available for the payment of such distributions and
whether or not such distributions are authorized or declared. Accrued but unpaid
distributions on the Series F Preferred Shares will accumulate as of the
Preferred Shares Distribution Payment Date on which they first become payable.
Accumulated and unpaid distributions will not bear interest.

      (d) Priority as to Distributions. (i) So long as any Series F Preferred
Shares are outstanding, no distribution of cash or other property shall be
authorized, declared, paid or set apart for payment on or with respect to any
class or series of common shares or any class or series of other Shares of the
Company ranking junior as to the payment of distributions or rights upon
voluntary or involuntary dissolution, liquidation or winding up of the Company
to the Series F Preferred Shares (such common shares or other junior Shares,
including, without limitation Series A Junior Participating Preferred Shares
authorized pursuant to Articles Supplementary filed with the SDAT on July 10,
1998, collectively, "Junior Shares"), nor shall any cash or other property be
set aside for or applied to the purchase, redemption or other acquisition for
consideration of any Series F Preferred Shares, any Parity Preferred Shares or
any Junior Shares, unless, in each case, all distributions accumulated on all
Series F Preferred Shares and all classes and series of outstanding Parity
Preferred Shares have been paid in full. The foregoing sentence will not
prohibit (i) distributions payable solely in Shares of the Company ranking
junior to the Series F Preferred Shares as to distributions and upon
liquidation, winding-up or dissolution, (ii) the conversion of Junior
<PAGE>

Shares or Parity Preferred Shares into Shares of the Company ranking junior to
the Series F Preferred Shares as to distributions and upon liquidation, winding
up or dissolution, and (iii) purchase by the Company of such Series F Preferred
Shares, Parity Preferred Shares or Junior Shares pursuant to Article 3 of the
Charter to the extent required to preserve the Company's status as a real estate
investment trust.

            (ii) So long as distributions have not been paid in full (or a sum
sufficient for such full payment is not irrevocably deposited in trust for
payment) upon the Series F Preferred Shares, all distributions authorized and
declared on the Series F Preferred Shares and all classes or series of
outstanding Parity Preferred Shares shall be authorized and declared so that the
amount of distributions authorized and declared per share of Series F Preferred
Shares and such other classes or series of Parity Preferred Shares shall in all
cases bear to each other the same ratio that accrued distributions per share on
the Series F Preferred Shares and such other classes or series of Parity
Preferred Shares (which shall not include any accumulation in respect of unpaid
distributions for prior distribution periods if such class or series of Parity
Preferred Shares do not have cumulative distribution rights) bear to each other.

      (e) No Further Rights. Holders of Series F Preferred Shares shall not be
entitled to any distributions, whether payable in cash, other property or
otherwise, in excess of the full cumulative distributions described herein.

      SECTION 4. Liquidation Preference.

      (a) Payment of Liquidating Distributions. Subject to the rights of holders
of Parity Preferred Shares and subject to equity securities ranking senior to
the Series F Preferred Shares with respect to rights upon any voluntary or
involuntary liquidation, dissolution or winding-up of the Company, the holders
of Series F Preferred Shares shall be entitled to receive out of the assets of
the Company legally available for distribution or the proceeds thereof, after
payment or provision for debts and other liabilities of the Company, but before
any payment or distributions of the assets shall be made to holders of common
shares or any other class or series of shares of the Company that ranks junior
to the Series F Preferred Shares as to rights upon liquidation, dissolution or
winding-up of the Company, an amount equal to the sum of(i) a liquidation
preference of $25 per Series F Preferred Share, and (ii) an amount equal to any
accumulated and unpaid distributions thereon, whether or not declared, to the
date of payment. In the event that, upon such voluntary or involuntary
liquidation, dissolution or winding-up, there are insufficient assets to permit
full payment of liquidating distributions to the holders of Series F Preferred
Shares and any Parity Preferred Shares, all payments of liquidating
distributions on the Series F Preferred Shares and such Parity Preferred Shares
shall be made so that the payments on the Series F Preferred Shares and such
Parity Preferred Shares shall in all cases bear to each other the same ratio
that the respective rights of the Series F Preferred Shares and such other
Parity Preferred Shares (which shall not include any accumulation in respect of
unpaid distributions for prior distribution periods if such Parity Preferred
Shares do not have cumulative distribution rights) upon liquidation, dissolution
or winding-up of the Company bear to each other.

      (b) Notice. Written notice of any such voluntary or involuntary
liquidation, dissolution or winding-up of the Company, stating the payment date
or dates when, and the place or places where, the amounts distributable in such
circumstances shall be payable, shall be given by (i) fax and (ii) by registered
mail, postage pre-paid. not less than thirty (30) and not more than sixty (60)
days prior to the payment date stated therein, to each record holder of the
Series F Preferred Shares at the respective addresses of such holders as the
same shall appear on the share transfer records of the Company.

      (c) No Further Rights. After payment of the full amount of the liquidating
distributions to which they are entitled, the holders of Series F Preferred
Shares will have no right or claim to any of the remaining assets of the
Company.

      (d) Consolidation. Merger or Certain Other Transactions. The voluntary
sale, conveyance, lease, exchange or transfer (for cash, shares of stock,
securities or other consideration) of all or substantially all of the property
or assets of the Company to, or the consolidation or merger or other business
combination of the Company with or into any corporation. trust or other entity
(or of any corporation, trust or other entity with or into the Company) shall
not be deemed to constitute a liquidation, dissolution or winding-up of the
Company.
<PAGE>

      SECTION 5. Optional Redemption.

      (a) Right of Optional Redemption. The Series F Preferred Shares may not be
redeemed prior to December 22, 2004. On or after such date, the Company shall
have the right to redeem the Series F Preferred Shares, in whole or in part, at
any time or from time to time, upon not less than thirty (30) nor more than
sixty (60) days' written notice, at a redemption price, payable in cash, equal
to $25 per share of Series F Preferred Shares plus accumulated and unpaid
distributions, whether or not declared, to the date of redemption. If fewer than
all of the outstanding Series F Preferred Shares are to be redeemed, the Series
F Preferred Shares to be redeemed shall be selected pro rata (as nearly as
practicable without creating fractional shares).

      (b) Limitation on Redemption. The Company may not redeem fewer than all of
the outstanding shares of Series F Preferred Shares unless all accumulated and
unpaid distributions have been paid on all outstanding Series F Preferred Shares
for all quarterly distribution periods terminating on or prior to the date of
redemption.

      (c) Procedures for Redemption. (i) Notice of redemption will be (i) faxed,
and (ii) mailed by the Company by registered mail, postage prepaid, not less
than thirty (30) nor more than sixty (60) days prior to the redemption date,
addressed to the respective holders of record of the Series F Preferred Shares
to be redeemed at their respective addresses as they appear on the transfer
records of the Company. No failure to give or defect in such notice shall affect
the validity of the proceedings for the redemption of any Series F Preferred
Shares except as to the holder to whom such notice was defective or not given.
In addition to any information required by law or by the applicable rules of any
exchange upon which the Series F Preferred Shares may be listed or admitted to
trading, each such notice shall state: (i) the redemption date, (ii) the
redemption price, (iii) the number of Series F Preferred Shares to be redeemed,
(iv) the place or places where such Series F Preferred Shares are to be
surrendered for payment of the redemption price, (v) that distributions on the
Series F Preferred Shares to be redeemed will cease to accumulate on such
redemption date and (vi) that payment of the redemption price and any
accumulated and unpaid distributions will be made upon presentation and
surrender of such Series F Preferred Shares. If fewer than all of the Series F
Preferred Shares held by any holder are to be redeemed, the notice mailed to
such holder shall also specify the number of Series F Preferred Shares held by
such holder to be redeemed.

            (ii) If the Company gives a notice of redemption in respect of
Series F Preferred Shares (which notice will be irrevocable) then, by 12:00
noon, New York City time, on the redemption date, the Company will deposit
irrevocably in trust for the benefit of the holders of the Series F Preferred
Shares being redeemed, funds sufficient to pay the applicable redemption price,
plus any accumulated and unpaid distributions, whether or not declared, if any,
on such shares to the date fixed for redemption, without interest, and will give
irrevocable instructions and authority to pay such redemption price and any
accumulated and unpaid distributions, whether or not declared, if any. on such
shares to the holders of the Series F Preferred Shares upon surrender of the
certificates for the Series F Preferred Shares by such holders at the place
designated in the notice of redemption. If fewer than all Series F Preferred
Shares evidenced by any certificate are being redeemed, a new certificate shall
be issued upon surrender of the certificate evidencing all Series F Preferred
Shares, evidencing the unredeemed Series F Preferred Shares without cost to the
holder thereof. On and after the date of redemption, distributions will cease to
accumulate on the Series F Preferred Shares or portions thereof called for
redemption, unless the Company defaults in the payment of such redemption price.
If any date fixed for redemption of Series F Preferred Shares is not a Business
Day, then payment of the redemption price payable on such date will be made on
the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay) except that, if such Business Day
falls in the next calendar year, such payment will be made on the immediately
preceding Business Day, in each case with the same force and effect as if made
on such date fixed for redemption. If payment of the redemption price or any
accumulated or unpaid distributions in respect of the Series F Preferred Shares
is improperly withheld or refused and not paid by the Company, distributions on
such Series F Preferred Shares will continue to accumulate from the original
redemption date to the date of payment, in which case the actual payment date
will be considered the date fixed for redemption for purposes of calculating the
applicable redemption price and any accumulated and unpaid distributions.
<PAGE>

      (d) Status of Redeemed Shares. Any Series F Preferred Shares that shall at
any time have been redeemed shall after such redemption, have the status of
authorized but unissued Shares, without designation as to class or series until
such shares are once more designated as part of a particular class or series by
the Board.

      SECTION 6. Voting Rights.

      (a) General. Holders of the Series F Preferred Shares will not have any
voting rights, except as set forth below.

      (b) Right to Elect Trustees. (i) If at any time full distributions shall
not have been timely made on any Series F Preferred Shares with respect to any
six (6) prior quarterly distribution periods, whether or not consecutive (a
"Preferred Distribution Default"), the holders of such Series F Preferred
Shares, voting together as a single class with the holders of each class or
series of Parity Preferred Shares upon which like voting rights have been
conferred and are exercisable, will have the right to elect two additional
Trustees to serve on the Company's Board (the "Preferred Shares Trustees") at a
special meeting called by the holders of record of at least 10% of the
outstanding Series F Preferred Shares or any such class or series of Parity
Preferred Shares or at the next annual meeting of Shareholders, and at each
subsequent annual meeting of Shareholders or special meeting for the election of
Trustees held in place thereof, until all such distributions in arrears and
distributions for the current quarterly period on the Series F Preferred Shares
and each such class or series of Parity Preferred Shares have been paid in full.

            (ii) At any time when such voting rights shall have vested, a proper
officer of the Company shall call or cause to be called, upon written request of
holders of record of at least 10% of the outstanding Series F Preferred Shares,
a special meeting of the holders of Series F Preferred Shares and all the series
of Parity Preferred Shares upon which like voting rights have been conferred and
are exercisable (collectively, the "Parity Securities") by mailing or causing to
be mailed to such holders a notice of such special meeting to be held not less
than ten and not more than 45 days after the date such notice is given. The
record date for determining holders of the Parity Securities entitled to notice
of and to vote at such special meeting will be the close of business on the
third Business Day preceding the day on which such notice is mailed. At any such
special meeting, all of the holders of the Parity Securities, by plurality vote,
voting together as a single class without regard to series will be entitled to
elect two Trustees on the basis of one vote per $25 of liquidation preference to
which such Parity Securities are entitled by their terms (excluding amounts in
respect of accumulated and unpaid dividends) and not cumulatively. The holder or
holders of one-third of the Parity Securities then outstanding, present in
person or by proxy, will constitute a quorum for the election of the Preferred
Shares Trustees except as otherwise provided by law. Notice of all meetings at
which holders of the Series F Preferred Shares shall be entitled to vote will be
given to such holders at their addresses as they appear in the transfer records.
At any such meeting or adjournment thereof in the absence of a quorum. subject
to the provisions of any applicable law, the holders of a majority of the votes
to which the Parity Securities are entitled, present in person or by proxy,
shall have the power to adjourn the meeting for the election of the Preferred
Shares Trustees, without notice other than an announcement at the meeting, until
a quorum is present. If a Preferred Distribution Default shall terminate after
the notice of a special meeting has been given but before such special meeting
has been held, the Company shall, as soon as practicable after such termination,
mail or cause to be mailed notice of such termination to holders of the Series F
Preferred Shares that would have been entitled to vote at such special meeting.

            (iii) If and when all accumulated distributions and the
distributions for the current distribution period on the Series F Preferred
Shares shall have been paid in full or a sum sufficient for such payment is
irrevocably deposited in trust for payment, the holders of the Series F
Preferred Shares shall be divested of the voting rights set forth in this
Section 6(b) herein (subject to revesting in the event of each and every
Preferred Distribution Default) and, if all distributions in arrears and the
distributions for the current distribution period have been paid in full or set
aside for payment in full on all other classes or series of Parity Preferred
Shares upon which like voting rights have been conferred and are exercisable,
the term and office of each Preferred Shares Trustee so elected shall terminate.
Any Preferred Shares Trustee may be removed at any time with or without cause by
the vote of, and shall not be removed otherwise than by the vote of, the holders
of record of a majority of the votes to which the outstanding Parity Securities
are entitled, when they have the voting rights set forth in this Section 6(b).
<PAGE>

So long as a Preferred Distribution Default shall continue, any vacancy in the
office of a Preferred Shares Trustee may be filled by written consent of the
Preferred Shares Trustee remaining in office, or if none remains in office, by a
vote of the holders of record of a majority of the votes to which the
outstanding Parity Securities are entitled, when they have the voting rights set
forth in this Section 6(b). The Preferred Shares Trustees shall each be entitled
to one vote per trustee on any matter.

      (c) Certain Voting Rights. So long as any Series F Preferred Shares remain
outstanding, the Company shall not, without the approval of the holders of at
least two-thirds of the Series F Preferred Shares outstanding at the time (i)
designate or create, or increase the authorized or issued amount of, any class
or series of shares ranking senior to the Series F Preferred Shares with respect
to payment of distributions or rights upon liquidation, dissolution or
winding-up of the Company or reclassify any authorized shares of the Company
into any such shares, or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such shares, (ii)
designate or create, or increase the authorized or issued amount of, any Parity
Preferred Shares or reclassify any authorized shares of the Company into any
such shares, or create, authorize or issue any obligations or security
convertible into or evidencing the right to purchase any such shares, but only
to the extent such Parity Preferred Shares are issued to an affiliate of the
Company, or (iii) either (A) consolidate, merge into or with, or convey,
transfer or lease its assets substantially as an entirety, to any corporation or
other entity, or (B) amend, alter or repeal the provisions of the Company's
Charter (including these Articles Supplementary) or Bylaws, whether by merger,
consolidation or otherwise, in each case that would materially and adversely
affect the powers. special rights, preferences, privileges or voting power of
the Series F Preferred Shares or the holders thereof, provided, however, that
with respect to the occurrence of a merger, consolidation or a sale or lease of
all or substantially all of the Company's assets as an entirety, so long as (a)
the Company is the surviving entity and the Series F Preferred Shares remain
outstanding with the terms thereof unchanged, or (b) the resulting, surviving or
transferee entity is a corporation or real estate investment trust organized
tinder the laws of any state and substitutes the Series F Preferred Shares for
other preferred Shares having substantially the same terms and same rights as
the Series F Preferred Shares, including with respect to distributions,
redemptions. transfers, voting rights and rights upon liquidation, dissolution
or winding-up of the Company, then the occurrence of any such event shall not be
deemed to materially and adversely affect such rights, privileges or voting
powers of the holders of the Series F Preferred Shares and no vote of the Series
F Preferred Shares shall be required; and provided further that any increase in
the amount of authorized Shares or the creation or issuance of any other class
or series of Shares, or any increase in an amount of authorized shares of each
class or series, in each case ranking either (a) junior to the Series F
Preferred Shares with respect to payment of distributions and the distribution
of assets upon liquidation, dissolution or winding-up of the Company, or (b) on
a parity with the Series F Preferred Shares with respect to payment of
distributions or the distribution of assets upon liquidation, dissolution or
winding-up of the Company to the extent such Shares are not issued to an
affiliate of the Company, shall not be deemed to materially and adversely affect
such rights, preferences, privileges or voting powers and no approval of the
Series F Preferred Shares shall be required.

      SECTION 7. Transfer Restrictions. The Series F Preferred Shares shall be
subject to the provisions of Article 3 of the Charter; provided, however, in no
event shall the Ownership Limit with respect to the Series F Preferred Shares
(as defined in the Charter) be decreased pursuant to Section 10 of Article 3 of
the Charter or otherwise (other than a decrease as a result of a retroactive
change in existing law that would require a decrease to retain real estate
investment trust status tinder the Internal Revenue Code of 1986, as amended).

      SECTION 8. No Conversion Rights. The holders of the Series F Preferred
Shares shall not have any rights to convert such shares into shares of any other
class or series of Shares or into any other securities of, or interest in. the
Company.

      SECTION 9. No Sinking Fund. No sinking fund shall be established for the
retirement or redemption of Series F Preferred Shares.

      SECTION 10. No Preemptive Rights. No holder of the Series F Preferred
Shares of the Company shall, as such holder, have any preemptive rights to
purchase or subscribe for additional Shares of the Company or any other security
of the Company which it may issue or sell.

                       (As Amended and Restated Effective
                             as of January 26, 1998)

                                    SECTION 1
                                     GENERAL

      1.1. Purpose. Cabot Industrial Trust, a Maryland real estate investment
trust (the "REIT"), established the Cabot Industrial Trust Long-Term Incentive
Plan (the "Plan") effective January 26, 1998 (the "Effective Date"). The
provisions that follow constitute an amendment and restatement of the Plan

      (a)   attract and retain employees and other persons providing services
            to the REIT and the Related Companies (as defined below);

      (b)   motivate Participants (as defined in subsection 1.2), by means of
            appropriate incentives, to achieve long-range goals;

      (c)   provide incentive compensation opportunities that are competitive
            with those of other corporations and real estate investment trusts;
            and

      (d)   further identify Participants' interests with those of the REIT's
            other shareholders through compensation that is based on the value
            of the REIT's common shares;

and thereby promote the long-term financial interest of the REIT and the Related
Companies, including the growth in value of the REIT's equity and enhancement of
long-term shareholder return. The term "Related Company" means any company
during any period in which it is a "subsidiary corporation" (as that term is
defined in section 424(f) of the Internal Revenue Code of 1986, as amended (the
"Code")), with respect to the REIT or any affiliate of the REIT which is
designated as a Related Company by the REIT Committee (as defined in subsection
5.1 below), including Cabot Industrial Properties, L.P. (the "Partnership") and
Cabot Advisors, Inc. (the "Management Company").

      1.2. Participation. Subject to the terms and conditions of the Plan, the
Committees (as described in Section 5) shall determine and designate, from time
to time, from among the Eligible Individuals (as defined below), those persons
who will
<PAGE>

be granted one or more awards under Sections 2 or 3 of the Plan (an "Award"),
and thereby become "Participants" in the Plan. In the discretion of the granting
Committee, and subject to the terms of the Plan, a Participant may be granted
any Award permitted under the provisions of the Plan, and more than one Award
may be granted to a Participant. Except as otherwise agreed by the REIT and the
Participant, or except as otherwise provided in the Plan, an Award under the
Plan shall not affect any previous Award under the Plan or an award under any
other plan maintained by the REIT or the Related Companies. For purposes of the
Plan, the term "Eligible Individual" shall mean any employee, officer,
consultant, adviser or member of the Board of the REIT or a Related Company;
provided, however, that a member of the Board of Trustees of the REIT (the
"Board") who is not an employee of the REIT or a Related Company (a
"Non-Employee Trustee") shall be granted Options in accordance with the formula
award provisions of subsection 2.3.

                                    SECTION 2

                                     OPTIONS

      2.1. Definitions. The grant of an "Option" under this Section 2 entitles
the Participant to purchase common shares of beneficial interest of the REIT
("Shares") or units of interest in the Partnership ("Units") at a price fixed at
the time the Option is granted, subject to the terms of this Section. Share
Options granted under this Section may be either Incentive Share Options or
Share Options that are Non-Qualified Options, as determined in the discretion of
the REIT Committee. An "Incentive Share Option" is a Share Option that is
intended to satisfy the requirements applicable to an "incentive stock option"
described in section 422 of the Code. A "Non-Qualified Option" is an Option that
is not intended to be an Incentive Share Option.

      2.2. Eligibility. Each Committee shall designate the Participants to whom
Options are to be granted under this Section and shall determine the number of
Shares or Units, as applicable, subject to each such Option. If the REIT
Committee grants Incentive Share Options, to the extent that the aggregate fair
market value of Shares with respect to which Incentive Share Options are
exercisable for the first time by any individual during any calendar year (under
all plans of the REIT and all related companies within the meaning of section
424(f) of the Code) exceeds $100,000, such Options shall be treated as
Non-Qualified Options, to the extent required by section 422 of the Code.

      2.3. Formula Awards of Options to Non-Employee Trustees. At the time of
his initial election or appointment as a Trustee (or, if later, as of the date
of closing of the initial public offering of Shares pursuant to the REIT's first
effective registration statement for the sale to the public of the Shares filed
under the Securities Act of 1933, as amended (the "Initial Public Offering")),
each Non-Employee Trustee shall automatically receive a Non-Qualified Option for
10,000 Shares, which Option shall become exercisable on the first anniversary
after the date of grant, provided the Non-Employee Trustee remains in continuous
service as a Non-Employee Trustee until such anniversary of the date of grant.
Thereafter, at the closing of each annual meeting of the REIT's shareholders,
each Non-Employee Trustee who has been reelected or who is continuing as a
Trustee as of the adjournment of the annual meeting shall automatically receive
a Non-Qualified Option for an additional 4,000 Shares, which Option shall become
exercisable on the first anniversary after the date of grant. To the extent
Options granted pursuant to subsection 2.2 of the Plan are adjusted pursuant to
subsection 4.4 of the Plan, Options granted under this subsection shall
automatically be adjusted in the same manner. All Options granted under this
subsection 2.3 shall provide for an exercise price per Share equal to the Fair
Market Value (as defined below) of a Share as of the date of grant (or par
value, if greater). Each Option granted under this subsection shall be awarded
with Dividend Equivalent Units, as described in subsection 3.1.

      2.4. Price. The exercise price for each Share purchasable under any
Non-Qualified Option granted to a Non-Employee Trustee is set forth in
subsection 2.3. The determination and payment of the purchase price of a Share
or Unit under each other Option granted under this Section shall be subject to
the following:

      (a)   The purchase price shall be established by the granting Committee at
            the time the Option is granted; provided, however, that:

            (i)   in no event shall the price of a Share Option be less than
                  the par value of a Share on such date;

            (ii)  in no event shall the purchase price of a Share under an
                  Incentive Share Option be less than the Fair Market Value of a
                  Share at the time the Option is granted and in the case of any
                  Incentive Share Option granted to an optionee who, at the time
                  the Option is granted, owns shares of beneficial interest
                  representing more than 10% of the voting power of all classes
                  of shares of


                                       3
<PAGE>

                  beneficial interest of the REIT or any of its subsidiaries
                  within the meaning of section 424(f) of the Code, the exercise
                  price for each Share purchasable under such Option shall not
                  be less than 110% of the Fair Market Value of a Share on the
                  date of grant of the Option; and

      (b)   Subject to the following provisions of this subsection, the full
            purchase price of each Share or Unit purchased upon the exercise of
            any Option shall be paid at the time of such exercise (or such later
            date as may be permitted by the Committee in the case of a cashless
            exercise) and, as soon as practicable thereafter, a certificate
            representing the Shares or Units so purchased shall be delivered to
            the person entitled thereto.

      (c)   The purchase price of a Share Option shall be payable in cash or
            in Shares (valued at Fair Market Value as of the day of exercise)
            that have been held by the Participant at least six months, or in
            any combination thereof, as determined by the REIT Committee.
            The purchase price of a Unit Option shall be payable in cash or
            in Units (valued at Fair Market Value as of the day of exercise)
            that have been held by the Participant at least six months, or in
            any combination thereof, as determined by the REIT Committee.

      (d)   The "Fair Market Value" of a Share or Unit as of any date shall be
            determined in accordance with the following rules:

            (i)   If the Shares are at the time listed or admitted to trading on
                  any stock exchange, then the Fair Market Value of a Share
                  shall be the average of the highest and lowest sales price per
                  Share on such date on the principal exchange on which the
                  Shares are then listed or admitted to trading or, if no such
                  sale is reported on that date, on the last preceding date on
                  which a sale was so reported.

            (ii)  If the Shares are not at the time listed or admitted to
                  trading on a stock exchange, the Fair Market Value of a Share
                  shall be the average of the lowest reported bid price and
                  highest reported asked price of the Shares on the date in
                  question in the over-the-counter market, as such prices are
                  reported in a publication of general circulation


                                       4
<PAGE>

                  selected by the REIT Committee and regularly reporting the
                  market price of Shares in such market.

            (iii) If the Shares are not listed or admitted to trading on any
                  stock exchange or traded in the over-the-counter market, the
                  Fair Market Value of a Share shall be as determined by the
                  REIT Committee in good faith.

            (iv)  For purposes of determining the Fair Market Value of Shares
                  that are sold pursuant to a cashless exercise program, Fair
                  Market Value shall be the price at which such Shares are sold.

            (v)   As of any date, the Fair Market Value of a Unit shall equal
                  the Fair Market Value of a Share on such date.

            (vi)  For a Share or Unit subject to an Option granted on the date
                  of the closing of the Initial Public Offering, the Fair Market
                  Value of such Share or Unit will be deemed to be the initial
                  public offering price for a Share.

      2.5. Exercise. Except as otherwise expressly provided in the Plan, an
Option granted under this Section shall be exercisable in accordance with the
following terms of this subsection:

      (a)   The terms and conditions relating to exercise of an Option
            granted pursuant to subsection 2.2 shall be established by the
            granting Committee, and may include, without limitation,
            conditions relating to completion of a specified period of
            service (subject to paragraph (b) below), achievement of
            performance standards prior to exercise of the Option or the
            achievement of Share ownership objectives by the Participant.
            The granting Committee, in its sole discretion, may accelerate
            the vesting of any Option under circumstances designated by it at
            the time the Option is granted or thereafter.

      (b)   No Option may be exercised by a Participant after the Expiration
            Date (as defined in subsection 2.7) applicable to that Option.

      2.6. Post-Exercise Limitations. The REIT Committee, in its discretion, may
impose such restrictions on Shares acquired pursuant to the exercise of a Share
Option or delivered in


                                       5
<PAGE>

connection with the right described in Section 4.2(e) of the Agreement of
Limited Partnership of Cabot Industrial Properties, L.P. providing for the
exchange of Units for Shares (the "Conversion Right") as it determines to be
desirable, including, without limitation, restrictions relating to disposition
of the Shares and forfeiture restrictions based on service, performance, Share
ownership by the Participant and such other factors as the REIT Committee
determines to be appropriate.

      2.7. Expiration Date. The "Expiration Date" with respect to an Option
granted pursuant to subsection 2.2 means the date established as the Expiration
Date by the granting Committee at the time of the grant; provided, however, that
unless determined otherwise by the Committee, the Expiration Date with respect
to any Option shall not be later than the earliest to occur of:

      (a)   the ten-year anniversary of the date on which the Option is granted;

      (b)   if the Participant's Date of Termination occurs by reason of
            death or Disability, the one-year anniversary of such Date of
            Termination; or

      (c)   if the Participant's Date of Termination occurs for reasons other
            than death or Disability, the three-month anniversary of such Date
            of Termination.

The "Expiration Date" with respect to any Option granted to a Non-Employee
Trustee pursuant to subsection 2.3 means the date which is the earlier to occur
of the ten-year anniversary of the date on which the Option is granted or the
five-year anniversary of the date his trusteeship terminates. For purposes of
the Plan, a Participant's "Date of Termination" shall be the date on which he
both ceases to be an employee of the REIT and the Related Companies and ceases
to perform material services for the REIT and the Related Companies, regardless
of the reason for the cessation; provided that a "Date of Termination" shall not
be considered to have occurred during the period in which the reason for the
cessation of services is a leave of absence approved by the REIT or the Related
Company which was the recipient of the Participant's services. Except as
otherwise provided by the Committee, a Participant shall be considered to have a
"Disability" during the period in which he is unable, by reason of a medically
determinable physical or mental impairment, to engage in the material and
substantial duties of his regular occupation, which condition is expected to be
permanent.

                                    SECTION 3

                   DIVIDEND AND DISTRIBUTION EQUIVALENT UNITS

      3.1. Award of Dividend Equivalent Units to Non-Employee Trustees. A
Non-Employee Trustee who is awarded a Share Option under subsection 2.3 of the
Plan shall also be entitled to receive "Dividend Equivalent Units" with respect
to the Share Option.

      (a)   Annual crediting of Dividend Equivalent Units. As of the last day of
            each calendar year, each Non-Employee Trustee shall be credited with
            a number of Dividend Equivalent Units equal to (i) the amount the
            REIT Committee determines to be the average dividend yield per Share
            for such calendar year, reduced by the amount that the REIT
            Committee determines to be the S&P 500 average dividend yield for
            such year, multiplied by (ii) the number of Shares underlying the
            Non-Employee Trustee's outstanding Share Options (reduced pro rata
            to reflect Shares underlying such Share Options that were not
            outstanding on the record date with respect to each dividend payment
            date during such year).

      (b)   Additional credits to reflect dividend payments on Dividend
            Equivalent Units. As of the last day of each calendar year, each
            Non-Employee Trustee shall be credited with additional Dividend
            Equivalent Units equal to (i) the amount the REIT Committee
            determines to be the average dividend yield per Share for such
            calendar year, multiplied by (ii) the number of Dividend Equivalent
            Units outstanding during such calendar year (reduced pro rata to
            reflect Dividend Equivalent Units that were not outstanding on each
            dividend payment date during such year).

      3.2. Terms and Conditions of Non-Employee Trustee Dividend Equivalent
Units. Dividend Equivalent Units of Non-Employee Trustees shall be subject to
the following terms and conditions:

      (a)   Dividend Equivalent Units of Non-Employee Trustees shall vest in
            accordance with the vesting schedule applicable to the Share Option
            with respect to which the Dividend Equivalent Unit was awarded.

      (b)   Each vested Dividend Equivalent Unit shall entitle the holder
            thereof to a Share on the last day of the calendar year in which
            occurs the first of (i) the date


                                       7
<PAGE>

            the Non-Employee Trustee exercises the Share Option with respect to
            which the Dividend Equivalent Unit was awarded, or (ii) the date
            such Option expires by its terms; provided, however, prior to the
            date the Shares would otherwise be payable, to the extent permitted
            by the REIT Committee, a Non-Employee Trustee may irrevocably elect
            to defer receipt of such Shares until the last date of a later
            calendar year, but in no event later than the last day of the
            calendar year in which occurs the tenth anniversary of the grant of
            the underlying Option. Any such deferral election shall be made in
            such form and at such times as the REIT Committee may determine and
            shall be subject to such other terms, conditions and limitations as
            the REIT Committee may establish.

      (c)   All Dividend Equivalent Units which are not vested upon the date a
            Non-Employee Trustee's trusteeship terminates shall be forfeited.

      (d)   Settlement of a Non-Employee Trustee's Dividend Equivalent Units
            shall be made in the form of whole Shares. Any fractional Shares
            shall be settled in cash.

      3.3. Award of Dividend and Distribution Equivalent Units to Participants
other than Non-Employee Trustees. To the extent determined by an affirmative
action of the granting Committee at the time an Option is awarded, a Participant
other than a Non-Employee Trustee who is awarded an Option under the Plan shall
also be entitled to receive "Dividend Equivalent Units" with respect to a Share
Option and "Distribution Equivalent Units" with respect to a Unit Option, as
applicable.

      (a)   Crediting of Dividend Equivalent Units. As of the last day of each
            calendar year, each Participant other than a Non-Employee Trustee
            who has been awarded Dividend Equivalent Units with respect to a
            Share Option shall be credited with a number of Dividend Equivalent
            Units equal to (i) the amount the REIT Committee determines to be
            the average dividend yield per Share for such calendar year, reduced
            by the amount that the REIT Committee determines to be the S&P 500
            average dividend yield for such year, multiplied by (ii) the number
            of Shares underlying the Participant's outstanding Share Option that
            are entitled to Awards under this Section 3 during such calendar
            year (reduced pro rata to reflect Shares underlying such Share
            Option that were not outstanding on the record date with respect to
            each


                                       8
<PAGE>

            dividend payment date during such year).

      (b)   Crediting of Distribution Equivalent Units. As of the last day of
            each calendar year, each Participant who has been awarded
            Distribution Equivalent Units with respect to a Unit Option shall be
            credited with a number of Distribution Equivalent Units equal to (i)
            the amount the REIT Committee determines to be the average
            distribution per Unit for such calendar year, reduced by the amount
            that the REIT Committee determines to be the S&P 500 average
            distribution yield for such year, multiplied by (ii) the number of
            Units underlying the Participant's outstanding Unit Option that are
            entitled to Awards under this Section 3 during such calendar year
            (reduced pro rata to reflect Units underlying such Unit Option that
            were not outstanding on the date each distribution was paid during
            such year).

      3.4. Terms and Conditions of Dividend and Distribution Equivalent Units
for Participants other than Non-Employee Trustees.

      (a)   The granting Committee shall determine whether a Dividend Equivalent
            Unit or a Distribution Equivalent Unit credited pursuant to
            subsection 3.3 shall vest over such period as may be designated by
            the Committee or only upon a Change in Control (as defined in
            subsection 4.7).

      (b)   Each vested Dividend Equivalent Unit and Distribution Equivalent
            Unit shall entitle the holder thereof to a Share or Unit, as
            applicable, on the last day of the calendar year in which occurs the
            first of (i) the date the Participant exercises the Option with
            respect to which the Dividend or Distribution Equivalent Unit was
            awarded, (ii) the date such Option expires by reason of termination
            of employment, or (iii) the tenth anniversary of the date on which
            the Option was granted or, if later, the first anniversary of the
            date the Dividend or Distribution Equivalent Unit is fully vested if
            the holder is employed by the REIT or a Related Company on such
            date; provided, however, prior to the date the Shares or Units would
            otherwise be payable, to the extent permitted by the REIT Committee,
            a Participant may irrevocably elect to defer receipt of such Shares
            or Units until the last day of a later calendar year, but in no
            event later than the last day of the calendar year in which occurs
            the tenth


                                       9
<PAGE>

            anniversary of the grant of the underlying Option. Any such deferral
            election shall be made in such form and at such times as the
            Committee may determine and shall be subject to such other terms,
            conditions and limitations as the Committee may establish.

      (c)   All Dividend Equivalent Units and Distribution Equivalent Units
            which are not vested upon the Participant's Date of Termination
            shall be forfeited.

      (d)   Settlement of all Dividend and Distribution Equivalent Units shall
            be made in the form of whole Shares or Units, as applicable. Any
            fractional Shares or Units shall be settled in cash.

                                    SECTION 4

                          OPERATION AND ADMINISTRATION

      4.1. Effective Date. The Plan was originally effective as of the date it
was adopted by the Board; provided, however, that Awards granted under the Plan
prior to its approval by shareholders were contingent on approval of the Plan by
the REIT's shareholders. The Plan shall be unlimited in duration and, in the
event of Plan termination, shall remain in effect as long as any Options awarded
under it are outstanding and have not been exercised, terminated or expired;
provided, however, that no new Awards shall be made under the Plan on or after
the tenth anniversary of the date on which the Plan was originally adopted by
the Board.

      4.2. Shares and Units Subject to Plan. The Shares with respect to which
Awards may be made under the Plan, including Shares delivered in connection with
the Conversion Right, shall be Shares currently authorized but unissued or
currently held or subsequently acquired by the REIT as treasury shares,
including Shares purchased in the open market or in private transactions.
Subject to the provisions of subsection 4.4, the number of Shares and Units
which may be issued with respect to Awards under the Plan shall not exceed
4,347,500 Shares or Units in the aggregate. In the event the number of
outstanding Shares and Units increases after the Effective Date, the maximum
number of Shares and Units reserved for Awards will be adjusted automatically so
that the maximum number equals 10% of the outstanding Shares and Units on a
fully-diluted basis, provided that the number of Shares reserved for grants of
Options designated as Incentive Share Options will not be so increased over the
number of such Shares as of the date the shareholders approve the Plan. Except


                                       10
<PAGE>

as otherwise provided herein, any Shares or Units subject to an Award which for
any reason expires or is terminated without issuance of Shares or Units
(including Shares reserved in connection with the Conversion Rights of the Units
and Shares or Units that are not issued because they are withheld to satisfy tax
withholding) shall again be available under the Plan.

      4.3. Reservation of Shares. There shall be reserved by the REIT at all
times for sale under the Plan and for exchange pursuant to a Conversion Right
for a Unit received upon the exercise of a Unit Option an aggregate number of
Shares equal to the maximum number of Shares and Units which may be subject to
the granting of Awards under subsection 4.2.

      4.4. Adjustment. In the event the REIT Committee shall determine that any
extraordinary dividend or other distribution (whether in the form of cash,
Shares, Units, other securities or other property), recapitalization, stock
split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase or exchange of Shares, Units or other
securities, the issuance of warrants or other rights to purchase Shares, Units
or other securities, or other similar corporate, trust or partnership
transaction or event affects the Shares or Units with respect to which Options
have been or may be issued under the Plan, such that an adjustment is determined
by the REIT Committee to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan, then the REIT Committee shall, in such manner as it may deem
equitable, adjust any or all of (i) the number and type of Shares and Units that
thereafter may be made the subject of Options, (ii) the number and type of
Shares and Units subject to outstanding Options, and (iii) the grant or exercise
price with respect to any Option, or, if deemed appropriate, make provisions for
a cash payment to the holder of any outstanding Option; provided, that:

      (a)   with respect to Incentive Share Options, no adjustment shall be made
            to the extent that the adjustment would cause the Option to violate
            section 422 of the Code or any successor provision;

            (b)   the number of Shares or Units subject to any Option shall
                  always be a whole number; and

            (c)   in the event of a merger or sale of substantially all of the
                  assets of the REIT, the Board, in its sole discretion, may
                  substitute awards of equal value for Awards under the Plan or
                  cancel outstanding Awards, provided that the Participant


                                       11
<PAGE>

                  receives an amount that the Board believes is reasonable
                  payment therefor.

      4.5. Individual Limits on Awards. Notwithstanding any other provision of
the Plan to the contrary, no Participant shall receive any Award of an Option
under the Plan to the extent that the sum of:

      (a)   the number of Shares and Units subject to such Award;

      (b)   the number of Shares and Units subject to all other prior Awards of
            Options under the Plan during the one-year period ending on the date
            of the Award; and

      (c)   the number of Shares and Units subject to all other prior awards of
            options granted to the Participant under other plans or arrangements
            of the REIT or the Partnership during the one-year period ending on
            the date of the award;

would exceed the Participant's Individual Limit under the Plan. The
determination made under the foregoing provisions of this subsection shall be
based on the Shares and Units subject to the Awards at the time of grant,
regardless of when the Awards become exercisable. Subject to the provisions of
subsection 4.4, a Participant's "Individual Limit" shall be 500,000 Shares or
500,000 Units, or any combination of the foregoing.

      4.6. Limitation on Grant of Options. Notwithstanding any provision of the
Plan to the contrary, in no event shall an Option be granted under the Plan if
the granting of such Option may, in the determination of the REIT Committee,
cause the REIT to lose its status as a real estate investment trust under
section 856 of the Code (including sections 856()(6) and 856(h) thereof) and
applicable regulations thereunder.

      4.7. Change in Control. In the event of a Change in Control of the REIT
(as defined below), all Options and related Awards which have not otherwise
expired shall become immediately exercisable and all other Awards shall become
fully vested. For purposes of the Plan, a "Change in Control" means the
happening of any of the following:

      (a)   the shareholders of the REIT approve a definitive agreement to merge
            the REIT into or consolidate the REIT with another entity, sell or
            otherwise dispose of all or substantially all of its assets or adopt
            a plan of liquidation, provided, however, that a Change in Control
            shall not be deemed to have occurred by reason


                                       12
<PAGE>

            of a transaction, or a substantially concurrent or otherwise related
            series of transactions, upon the completion of which 50% or more of
            the beneficial ownership of the voting power of the REIT, the
            surviving corporation or corporation directly or indirectly
            controlling the REIT or the surviving corporation, as the case may
            be, is held by the same persons (as defined below) (although not
            necessarily in the same proportion) as held the beneficial ownership
            of the voting power of the REIT immediately prior to the transaction
            or the substantially concurrent or otherwise related series of
            transactions, except that upon the completion thereof, employees or
            employee benefit plans of the REIT may be a new holder of such
            beneficial ownership; provided, further, that any transaction
            described in this paragraph (a) with an "Affiliate" of the REIT (as
            defined in the Securities Exchange Act of 1934, as amended (the
            "Exchange Act")) shall not be treated as a Change in Control; or

      (b)   the "beneficial ownership" (as defined in Rule 13d-3 under the
            Exchange Act) of securities representing 25% or more of the combined
            voting power of the REIT is acquired, other than from the REIT, by
            any "person" as defined in Sections 13(d) and 14(d) of the Exchange
            Act (other than any trustee or other fiduciary holding securities
            under an employee benefit or other similar stock plan of the REIT);
            or

      (c)   at any time during any period of two consecutive years, individuals
            who at the beginning of such period were members of the Board cease
            for any reason to constitute at least a majority thereof (unless the
            election, or the nomination for election by the REIT's shareholders,
            of each new trustee was approved by a vote of at least two-thirds of
            the trustees still in office at the time of such election or
            nomination who were trustees at the beginning of such period).

      4.8. Limit on Distribution. Distribution of Shares or Units under the Plan
shall be subject to the following:

      (a)   Notwithstanding any other provision of the Plan, the REIT shall have
            no liability to deliver any Shares or Units under the Plan unless
            such delivery would comply with all applicable laws and the
            applicable requirements of any securities exchange or similar
            entity.


                                       13
<PAGE>

      (b)   In the case of a Participant who is subject to Section 16(a) and
            16(b) of the Exchange Act, the REIT Committee may, at any time, add
            such conditions and limitations to any Award to such Participant, or
            any feature of any such Award, as the REIT Committee, in its sole
            discretion, deems necessary or desirable to comply with Section
            16(a) or 16(b) and the rules and regulations thereunder or to obtain
            any exemption therefrom.

      (c)   To the extent that the Plan provides for issuance of certificates to
            reflect the transfer of Shares or Units, the transfer of such Shares
            or Units may be effected on a non-certificated basis, to the extent
            not prohibited by applicable law or the rules of any stock exchange.

      4.9. Withholding. All Awards and other payments under the Plan are subject
to withholding of all applicable taxes, which withholding obligations with
respect to Share Options may be satisfied, with the consent of the REIT
Committee, through the surrender of Shares which the Participant already owns or
to which a Participant is otherwise entitled under the Plan; provided, however,
previously-owned Shares that have been held by the Participant less than six
months or Shares to which the Participant is entitled under the Plan may only be
used to satisfy the minimum tax withholding required by applicable law.

      4.10. Transferability. Awards under the Plan are not transferable except
as designated by the Participant by will or by the laws of descent and
distribution. In no event shall an Incentive Share Option be transferable to the
extent that such transferability would violate the requirements applicable to
such option under Code section 422. To the extent that the Participant who
receives an Award under the Plan has the right to exercise such Award, the Award
may be exercised during the lifetime of the Participant only by the Participant.
Notwithstanding the foregoing provisions of this subsection, the Committee may
permit Awards under the Plan to be transferred to or for the benefit of the
Participant's family (including, without limitation, to a trust or partnership
for the benefit of a Participant's family), subject to such limits as the
Committee may establish. In no event shall an Incentive Share Option be
transferable to the extent that such transferability would violate the
requirements applicable to such option under Code section 422.

      4.11. Notices. Any notice or document required to be filed with the
granting Committee under the Plan will be properly filed if delivered or mailed
by registered mail, postage prepaid, to


                                       14
<PAGE>

such Committee, in care of the REIT or the Management Company, as applicable, at
its principal executive offices. The Committee may, by advance written notice to
affected persons, revise such notice procedure from time to time. Any notice
required under the Plan (other than a notice of election) may be waived by the
person entitled to notice.

      4.12. Form and Time of Elections. Unless otherwise specified herein, each
election required or permitted to be made by any Participant or other person
entitled to benefits under the Plan, and any permitted modification or
revocation thereof, shall be in writing filed with the Committee at such times,
in such form, and subject to such restrictions and limitations, not inconsistent
with the terms of the Plan, as the Committee shall require.

      4.13. Option Agreement. At the time of an Award to a Participant under the
Plan, the granting Committee may require a Participant to enter into an
agreement with the REIT or the Management Company, as applicable (the
"Agreement"), in a form specified by the Committee, agreeing to the terms and
conditions of the Plan and to such additional terms and conditions, not
inconsistent with the Plan, as the Committee may, in its sole discretion,
prescribe.

      4.14.  Limitation of Implied Rights.

      (a)   Neither a Participant nor any other person shall, by reason of the
            Plan, acquire any right in or title to any assets, funds or property
            of the REIT or any Related Company whatsoever, including, without
            limitation, any specific funds, assets, or other property which the
            REIT or any Related Company, in its sole discretion, may set aside
            in anticipation of a liability under the Plan. A Participant shall
            have only a contractual right to the amounts, if any, payable under
            the Plan, unsecured by any assets of the REIT and any Related
            Company. Nothing contained in the Plan shall constitute a guarantee
            by the REIT or any Related Company that the assets of such companies
            shall be sufficient to pay any benefits to any person.


                                       15
<PAGE>

      (b)   The Plan does not constitute a contract of employment, and selection
            as a Participant will not give any employee the right to be retained
            in the employ of the REIT or any Related Company, nor any right or
            claim to any benefit under the Plan, unless such right or claim has
            specifically accrued under the terms of the Plan. Except as
            otherwise provided in the Plan, no Award under the Plan shall confer
            upon the holder thereof any right as a shareholder of the REIT or as
            a holder of interests in the Partnership prior to the date on which
            he fulfills all service requirements and other conditions for
            receipt of such rights and Shares or Units are registered in his
            name.

      4.15. Evidence. Evidence required of anyone under the Plan may be by
certificate, affidavit, document or other information which the person acting on
it considers pertinent and reliable, and signed, made or presented by the proper
party or parties.

      4.16. Action by REIT or Related Company. Any action required or permitted
to be taken by the REIT or any Related Company shall be by resolution of its
board of trustees or directors, as applicable, or by action of one or more
members of the board (including a committee of the board) who are duly
authorized to act for the board or (except to the extent prohibited by
applicable law or the rules of any stock exchange) by a duly authorized officer
of the REIT.

      4.17. Gender and Number. Where the context admits, words in any gender
shall include any other gender, words in the singular shall include the plural
and the plural shall include the singular.

      4.18. Applicable Law. The provisions of the Plan shall be construed in
accordance with the laws of the State of Maryland, without giving effect to
choice of law principles.

                                    SECTION 5

                                   COMMITTEES

      5.1. Administration. The authority to control and manage the operation and
administration of the Plan shall be vested in a REIT Committee and a Management
Company Committee (the "Committees") in accordance with this Section 5.

      5.2. Selection of REIT Committee. So long as the REIT is


                                       16
<PAGE>

subject to Section 16 of the Exchange Act, the Committee shall be selected by
the Board and shall consist of not fewer than two members of the Board or such
greater number as may be required for compliance with Rule 16b-3 issued under
the Exchange Act.

      5.3. Powers of Committees. The authority to manage and control the
operation and administration of the Plan shall be vested in the Committees,
subject to the following:

      (a)   Subject to the provisions of the Plan, the REIT Committee will have
            the authority and discretion to grant Share Options and Unit Options
            and Dividend and Distribution Equivalent Unit rights to individuals
            who, at the time of grant, perform services for the REIT or the
            Partnership, or who are officers, trustees, directors or other
            persons subject to Section 16(a) of the Exchange Act with respect to
            the REIT. The Management Company Committee shall have sole and
            exclusive authority to grant Unit Options and Distribution
            Equivalent Unit rights to persons who, at the time of grant, perform
            services for the Management Company and are not officers, trustees,
            directors or other persons subject to Section 16(a) of the Exchange
            Act with respect to the REIT. Each Committee shall have the
            authority to determine the time or times of receipt, to determine
            the types of Awards and the number of Shares or Units covered by the
            Awards, to establish the terms, conditions, performance criteria,
            restrictions, and other provisions of such Awards, and to cancel or
            suspend Awards. In making such Award determinations, the Committee
            may take into account the nature of services rendered by the
            respective individual, the individual's present and potential
            contribution to the REIT's success and such other factors as the
            Committee deems relevant.

      (b)   The Committee will have the authority and discretion to interpret
            the Plan, to establish, amend and rescind any rules and regulations
            relating to the Plan, to determine the terms and provisions of any
            agreements made pursuant to the Plan and to make all other
            determinations that may be necessary or advisable for the
            administration of the Plan.

      (c)   Any interpretation of the Plan by the Committee and any decision
            made by it under the Plan is final and binding on all persons.

      (d)   Except as otherwise expressly provided in the Plan,


                                       17
<PAGE>

            where the Committee is authorized to make a determination with
            respect to any Award, such determination shall be made at the time
            the Award is made, except that the Committee may reserve the
            authority to have such determination made by the Committee in the
            future (but only if such reservation is made at the time the Award
            is granted and is expressly stated in the Agreement reflecting the
            Award).

      5.4. Delegation by Committee. Except to the extent prohibited by
applicable law or the rules of any stock exchange or NASDAQ (if appropriate), a
Committee may allocate all or any portion of its responsibilities and powers to
any one or more of its members and may delegate all or any part of its
responsibilities and powers to any person or persons selected by it. Any such
allocation or delegation may be revoked by the Committee at any time.

      5.5. Information to be Furnished to Committees. The REIT and Related
Companies shall furnish the Committee such data and information as may be
required for it to discharge its duties. The records of the REIT and Related
Companies as to an employee's or Participant's employment (or other provision of
services), termination of employment (or cessation of the provision of
services), leave of absence, reemployment and compensation shall be conclusive
on all persons unless determined to be incorrect. Participants and other persons
entitled to benefits under the Plan must furnish the Committees such evidence,
data or information as the Committees consider desirable to carry out the terms
of the Plan.

      5.6. Liability and Indemnification of Committees. No member or authorized
delegate of either Committee shall be liable to any person for any action taken
or omitted in connection with the administration of the Plan unless attributable
to his own fraud or willful misconduct; nor shall the REIT or any Related
Company be liable to any person for any such action unless attributable to fraud
or willful misconduct on the part of a trustee or employee of the REIT or
Related Company. Each Committee, the individual members thereof, and persons
acting as the authorized delegates of the Committee under the Plan, shall be
indemnified by the REIT against any and all liabilities, losses, costs and
expenses (including legal fees and expenses) of whatsoever kind and nature which
may be imposed on, incurred by or asserted against the Committee or its members
or authorized delegates by reason of the performance of a Committee function if
the Committee or its members or authorized delegates did not act dishonestly or
in willful violation of the law or regulation


                                       18
<PAGE>

under which such liability, loss, cost or expense arises. This indemnification
shall not duplicate but may supplement any coverage available under any
applicable insurance.

                                    SECTION 6

                            AMENDMENT AND TERMINATION

      The Board may, at any time, amend or terminate the Plan, provided that,
subject to subsection 4.4 (relating to certain adjustments to shares), no
amendment or termination may materially adversely affect the rights of any
Participant or beneficiary under any Award made under the Plan prior to the date
such amendment is adopted by the Board.

                             CABOT INDUSTRIAL TRUST
                          1999 LONG-TERM INCENTIVE PLAN

                                    SECTION 1
                                     GENERAL

      1.1. Purpose. The Cabot Industrial Trust 1999 Long-Term Incentive Plan
(the "Plan") has been established effective December 22, 1999 (the "Effective
Date") by Cabot Industrial Trust, a Maryland real estate investment trust (the
"REIT") to:

      (a)   attract and retain employees and other persons providing services to
            the REIT and the Related Companies (as defined below);

      (b)   motivate Participants (as defined in subsection 1.2), by means of
            appropriate incentives, to achieve long-range goals;

      (c)   provide incentive compensation opportunities that are competitive
            with those of other corporations and real estate investment trusts;
            and

      (d)   further identify Participants' interests with those of the REIT's
            other shareholders through compensation that is based on the value
            of the REIT's common shares;

and thereby promote the long-term financial interest of the REIT and the Related
Companies, including the growth in value of the REIT's equity and enhancement of
long-term shareholder return. The term "Related Company" means any company
during any period in which it is a "subsidiary corporation" (as that term is
defined in section 424(f) of the Internal Revenue Code of 1986, as amended (the
"Code")), with respect to the REIT or any affiliate of the REIT which is
designated as a Related Company by the REIT Committee (as defined in subsection
6.1 below), including Cabot Industrial Properties, L.P. (the "Partnership") and
Cabot Advisors, Inc. (the "Management Company"). The Plan is intended to be a
broadly-based plan within the meaning of the shareholder approval policy of the
New York Stock Exchange listing requirements in which all employees of the REIT
and the Related Companies shall be eligible to participate.

      1.2. Participation. Subject to the terms and conditions of the Plan, the
Committees (as described in Section 6) shall determine and designate, from time
to time, from among the Eligible Individuals (as defined below), those persons
who will be granted one or more awards under Sections 2, 3 or 4 of the Plan (an
"Award"), and thereby become "Participants" in the Plan. In the discretion of
the granting Committee, and subject to the terms of the Plan, a Participant may
be granted any Award permitted under the provisions of the Plan, and more than
one Award may be granted to a Participant. Except as otherwise agreed by the
REIT and the Participant, or except as otherwise provided in the Plan, an Award
under the Plan shall not affect any previous Award under the Plan or an award
under any other plan maintained by the REIT or the Related Companies. For
purposes of the Plan, the term "Eligible Individual" shall mean any employee,
officer, consultant, adviser or member of the Board of the REIT or a Related
Company; provided, however, that a member

                                     OPTIONS

of the Board of Trustees of the REIT (the "Board") who is not an employee of the
REIT or a Related Company shall not be an Eligible Individual.

      2.1. Definitions. The grant of an "Option" under this Section 2 entitles
the Participant to purchase common shares of beneficial interest of the REIT
("Shares") or units of interest in the Partnership ("Units") at a price fixed at
the time the Option is granted, subject to the terms of this Section. Share
Options granted under this Section will be Share Options that are Non-Qualified
Options. A "Non-Qualified Option" is an Option that is not intended to satisfy
the requirements of an "incentive stock option" described in section 422 of the
Code.

      2.2. Eligibility. Each Committee shall designate the Participants to whom
Options are to be granted under this Section and shall determine the number of
Shares or Units, as applicable, subject to each such Option.

      2.3. Price. The determination and payment of the purchase price of a Share
or Unit under each other Option granted under this Section shall be subject to
the following:

      (a)   The purchase price shall be established by the granting Committee at
            the time the Option is granted; provided, however, that in no event
            shall the price of a Share Option be less than the par value of a
            Share on such date.

      (b)   Subject to the following provisions of this subsection, the full
            purchase price of each Share or Unit purchased upon the exercise of
            any Option shall be paid at the time of such exercise (or such later
            date as may be permitted by the Committee in the case of a cashless
            exercise) and, as soon as practicable thereafter, a certificate
            representing the Shares or Units so purchased shall be delivered to
            the person entitled thereto.

      (c)   The purchase price of a Share Option shall be payable in cash or in
            Shares (valued at Fair Market Value as of the day of exercise) that
            have been held by the Participant at least six months, or in any
            combination thereof, as determined by the REIT Committee. The
            purchase price of a Unit Option shall be payable in cash or in Units
            (valued at Fair Market Value as of the day of exercise) that have
            been held by the Participant at least six months, or in any
            combination thereof, as determined by the REIT Committee.

      (d)   The "Fair Market Value" of a Share or Unit as of any date shall be
            determined in accordance with the following rules:


                                       2
<PAGE>

            (i)   If the Shares are at the time listed or admitted to trading on
                  any stock exchange, then the Fair Market Value of a Share
                  shall be the average of the highest and lowest sales price per
                  Share on such date on the principal exchange on which the
                  Shares are then listed or admitted to trading or, if no such
                  sale is reported on that date, on the last preceding date on
                  which a sale was so reported.

            (ii)  If the Shares are not at the time listed or admitted to
                  trading on a stock exchange, the Fair Market Value of a Share
                  shall be the average of the lowest reported bid price and
                  highest reported asked price of the Shares on the date in
                  question in the over-the-counter market, as such prices are
                  reported in a publication of general circulation selected by
                  the REIT Committee and regularly reporting the market price of
                  Shares in such market.

            (iii) If the Shares are not listed or admitted to trading on any
                  stock exchange or traded in the over-the-counter market, the
                  Fair Market Value of a Share shall be as determined by the
                  REIT Committee in good faith.

            (iv)  For purposes of determining the Fair Market Value of Shares
                  that are sold pursuant to a cashless exercise program, Fair
                  Market Value shall be the price at which such Shares are sold.

            (v)   As of any date, the Fair Market Value of a Unit shall equal
                  the Fair Market Value of a Share on such date.

      2.4. Exercise. Except as otherwise expressly provided in the Plan, an
Option granted under this Section shall be exercisable in accordance with the
following terms of this subsection:

      (a)   The terms and conditions relating to exercise of an Option shall be
            established by the granting Committee, and may include, without
            limitation, conditions relating to completion of a specified period
            of service (subject to paragraph (b) below), achievement of
            performance standards prior to exercise of the Option or the
            achievement of Share ownership objectives by the Participant. The
            granting Committee, in its sole discretion, may accelerate the
            vesting of any Option under circumstances designated by it at the
            time the Option is granted or thereafter.

      (b)   No Option may be exercised by a Participant after the Expiration
            Date (as defined in subsection 2.6) applicable to that Option.

      2.5. Post-Exercise Limitations. The REIT Committee, in its discretion, may
impose such restrictions on Shares acquired pursuant to the exercise of a Share
Option or delivered in connection with the right described in Section


                                       3
<PAGE>

4.2(e) of the Agreement of Limited Partnership of Cabot Industrial Properties,
L.P. providing for the exchange of Units for Shares (the "Conversion Right") as
it determines to be desirable, including, without limitation, restrictions
relating to disposition of the Shares and forfeiture restrictions based on
service, performance, Share ownership by the Participant and such other factors
as the REIT Committee determines to be appropriate.

      2.6. Expiration Date. The "Expiration Date" with respect to an Option
means the date established as the Expiration Date by the granting Committee at
the time of the grant; provided, however, that unless determined otherwise by
the Committee, the Expiration Date with respect to any Option shall not be later
than the earliest to occur of:

      (a)   the ten-year anniversary of the date on which the Option is granted;

      (b)   if the Participant's Date of Termination occurs by reason of death
            or Disability, the one-year anniversary of such Date of Termination;
            or

      (c)   if the Participant's Date of Termination occurs for reasons other
            than death or Disability, the three-month anniversary of such Date
            of Termination.

For purposes of the Plan, a Participant's "Date of Termination" shall be the
date on which he both ceases to be an employee of the REIT and the Related
Companies and ceases to perform material services for the REIT and the Related
Companies, regardless of the reason for the cessation; provided that a "Date of
Termination" shall not be considered to have occurred during the period in which
the reason for the cessation of services is a leave of absence approved by the
REIT or the Related Company which was the recipient of the Participant's
services. Except as otherwise provided by the Committee, a Participant shall be
considered to have a "Disability" during the period in which he is unable, by
reason of a medically determinable physical or mental impairment, to engage in
the material and substantial duties of his regular occupation, which condition
is expected to be permanent.

                                    SECTION 3

                   DIVIDEND AND DISTRIBUTION EQUIVALENT UNITS

      3.1. Award of Dividend and Distribution Equivalent Units. To the extent
determined by an affirmative action of the granting Committee at the time an
Option is awarded, a Participant who is awarded an Option under the Plan shall
also be entitled to receive "Dividend Equivalent Units" with respect to a Share
Option and "Distribution Equivalent Units" with respect to a Unit Option, as
applicable.

      (a)   Crediting of Dividend Equivalent Units. Except to the extent


                                       4
<PAGE>

            provided otherwise in a Participant's Option agreement, as of the
            last day of each calendar year, each Participant who has been
            awarded Dividend Equivalent Units with respect to a Share Option
            shall be credited with a number of Dividend Equivalent Units equal
            to (i) the amount the REIT Committee determines to be the average
            dividend yield per Share for such calendar year, reduced by the
            amount that the REIT Committee determines to be the S&P 500 average
            dividend yield for such year, multiplied by (ii) the number of
            Shares underlying the Participant's outstanding Share Option that
            are entitled to Awards under this Section 3 during such calendar
            year (reduced pro rata to reflect Shares underlying such Share
            Option that were not outstanding on the record date with respect to
            each dividend payment date during such year).

      (b)   Crediting of Distribution Equivalent Units. Except to the extent
            provided otherwise in a Participant's Option agreement, as of the
            last day of each calendar year, each Participant who has been
            awarded Distribution Equivalent Units with respect to a Unit Option
            shall be credited with a number of Distribution Equivalent Units
            equal to (i) the amount the REIT Committee determines to be the
            average distribution per Unit for such calendar year, reduced by the
            amount that the REIT Committee determines to be the S&P 500 average
            distribution yield for such year, multiplied by (ii) the number of
            Units underlying the Participant's outstanding Unit Option that are
            entitled to Awards under this Section 3 during such calendar year
            (reduced pro rata to reflect Units underlying such Unit Option that
            were not outstanding on the date each distribution was paid during
            such year).

      3.2.  Terms and Conditions of Dividend and Distribution Equivalent Units.

      (a)   The granting Committee shall determine whether a Dividend Equivalent
            Unit or a Distribution Equivalent Unit credited pursuant to
            subsection 3.1 shall vest over such period as may be designated by
            the Committee or only upon a Change in Control (as defined in
            subsection 5.7).

      (b)   Each vested Dividend Equivalent Unit and Distribution Equivalent
            Unit shall entitle the holder thereof to a Share or Unit, as
            applicable, on the last day of the calendar year in which occurs the
            first of (i) the date the Participant exercises the Option with
            respect to which the Dividend or Distribution Equivalent Unit was
            awarded, (ii) the date such Option expires by reason of termination
            of employment, or (iii) the tenth anniversary of the date on which
            the Option was granted or, if later, the first anniversary of the
            date the Dividend or Distribution Equivalent Unit is fully vested if
            the holder is employed by the REIT or a Related Company on such
            date; provided, however, prior to the date the Shares or Units would
            otherwise be payable, to the extent


                                       5
<PAGE>

            permitted by the REIT Committee, a Participant may irrevocably elect
            to defer receipt of such Shares or Units until the last day of a
            later calendar year, but in no event later than the last day of the
            calendar year in which occurs the tenth anniversary of the grant of
            the underlying Option. Any such deferral election shall be made in
            such form and at such times as the Committee may determine and shall
            be subject to such other terms, conditions and limitations as the
            Committee may establish.

      (c)   All Dividend Equivalent Units and Distribution Equivalent Units
            which are not vested upon the Participant's Date of Termination
            shall be forfeited.

      (d)   Settlement of all Dividend and Distribution Equivalent Units shall
            be made in the form of whole Shares or Units, as applicable. Any
            fractional Shares or Units shall be settled in cash.

                                    SECTION 4

                                  SHARE AWARDS

      4.1. Definition. Subject to the terms of this Section, a Share Award under
the Plan is a grant of Shares to a Participant, the earning, vesting or
distribution of which is subject to one or more conditions established by the
REIT Committee. Such conditions may relate to events (such as performance or
continued employment) occurring before or after the date the Share Award is
granted, or the date the Shares are earned by, vested in or delivered to the
Participant. If the vesting of Share Awards is subject to conditions occurring
after the date of grant, the period beginning on the date of grant of a Share
Award and ending on the vesting or forfeiture of such Shares (as applicable) is
referred to as the "Restricted Period". Share Awards may provide for delivery of
the shares of Shares at the time of grant or may provide for a deferred delivery
date. A Share Award may, but need not, be made in conjunction with a cash-based
incentive compensation program maintained by the REIT and may, but need not, be
in lieu of cash otherwise awardable under such program.

      4.2. Eligibility. The REIT Committee shall designate the Participants to
whom Share Awards are to be granted and the number of Shares that are subject to
each such Award.

      4.3. Terms and Conditions of Awards. Share Awards granted to Participants
under the Plan shall be subject to the following terms and conditions:

      (a)   Beginning on the date of grant (or, if later, the date of
            distribution) of Shares comprising a Share Award, and including any
            applicable Restricted Period, the Participant as owner of such
            Shares shall have the right to vote such Shares.


                                       6
<PAGE>

      (b)   Payment of dividends with respect to Share Awards shall be subject
            to the following:

            (i)   On and after the date that a Participant has a fully earned
                  and vested right to the Shares comprising a Share Award and
                  the Shares have been distributed to the Participant, the
                  Participant shall have all dividend rights (and other rights)
                  of a shareholder with respect to such Shares.

            (ii)  Prior to the date that a Participant has a fully earned and
                  vested right to the shares comprising a Share Award, the REIT
                  Committee, in its sole discretion, may award Dividend Rights
                  with respect to such shares.

            (iii) On and after the date that a Participant has a fully earned
                  and vested right to the Shares comprising a Share Award, but
                  before the Shares have been distributed to the Participant,
                  the Participant shall be entitled to Dividend Rights with
                  respect to such Shares, at the time and in the form determined
                  by the REIT Committee.

            (iv)  A "Dividend Right" with respect to shares comprising a Share
                  Award shall entitle the Participant, as of each dividend
                  payment date, to an amount equal to the dividends payable with
                  respect to a Share multiplied by the number of such Shares.
                  Dividend Rights shall be settled in cash or in Shares valued
                  at Fair Market Value as of the date of settlement, as
                  determined by the REIT Committee, shall be payable at the time
                  determined by the REIT Committee and shall be subject to such
                  other terms and conditions as the REIT Committee may
                  determine.

                                   SECTION 5

                         OPERATION AND ADMINISTRATION

      5.1. Effective Date. The Plan shall be effective as of the date it was
adopted by the Board. The Plan shall be unlimited in duration and, in the event
of Plan termination, shall remain in effect as long as any Awards awarded under
it are outstanding and have not been exercised, terminated or expired; provided,
however, that no new Awards shall be made under the Plan on or after the tenth
anniversary of the date on which the Plan was originally adopted by the Board.

      5.2. Shares and Units Subject to Plan. The Shares with respect to which
Awards may be made under the Plan, including Shares delivered in connection with
the Conversion Right, shall be Shares currently authorized but unissued or
currently held or subsequently acquired by the REIT as treasury


                                       7
<PAGE>

shares, including Shares purchased in the open market or in private
transactions. Subject to the provisions of subsection 5.4, the number of Shares
and Units which may be issued with respect to Awards under the Plan shall not
exceed 2,000,000 Shares or Units in the aggregate. Except as otherwise provided
herein, any Shares or Units subject to an Award which for any reason expires or
is terminated without issuance of Shares or Units (including Shares reserved in
connection with the Conversion Rights of the Units and Shares or Units that are
not issued because they are withheld to satisfy tax withholding) shall again be
available under the Plan.

      5.3. Reservation of Shares. There shall be reserved by the REIT at all
times for sale under the Plan and for exchange pursuant to a Conversion Right
for a Unit received upon the exercise of a Unit Option an aggregate number of
Shares equal to the maximum number of Shares and Units which may be subject to
the granting of Awards under subsection 5.2.

      5.4. Adjustment. In the event the REIT Committee shall determine that any
extraordinary dividend or other distribution (whether in the form of cash,
Shares, Units, other securities or other property), recapitalization, stock
split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase or exchange of Shares, Units or other
securities, the issuance of warrants or other rights to purchase Shares, Units
or other securities, or other similar corporate, trust or partnership
transaction or event affects the Shares or Units with respect to which Awards
have been or may be issued under the Plan, such that an adjustment is determined
by the REIT Committee to be appropriate in order to prevent dilution or
enlargement of the benefits or potential benefits intended to be made available
under the Plan, then the REIT Committee shall, in such manner as it may deem
equitable, adjust any or all of (i) the number and type of Shares and Units that
thereafter may be made the subject of Awards, (ii) the number and type of Shares
and Units subject to outstanding Awards, and (iii) the grant or exercise price
with respect to any Option, or, if deemed appropriate, make provisions for a
cash payment to the holder of any outstanding Award; provided, that:

      (a)   the number of Shares or Units subject to any Award shall always be a
            whole number; and

      (b)   in the event of a merger or sale of substantially all of the assets
            of the REIT, the Board, in its sole discretion, may substitute
            awards of equal value for Awards under the Plan or cancel
            outstanding Awards, provided that the Participant receives an amount
            that the Board believes is reasonable payment therefor.

      5.5. Individual Limits on Awards. Notwithstanding any other provision of
the Plan to the contrary, no Participant shall receive any Award of an Option
under the Plan to the extent that the sum of:

      (a)   the number of Shares and Units subject to such Award;


                                       8
<PAGE>

      (b)   the number of Shares and Units subject to all other prior Awards of
            Options under the Plan during the one-year period ending on the date
            of the Award; and

      (c)   the number of Shares and Units subject to all other prior awards of
            options granted to the Participant under other plans or arrangements
            of the REIT or the Partnership during the one-year period ending on
            the date of the award;

would exceed the Participant's Individual Limit under the Plan. The
determination made under the foregoing provisions of this subsection shall be
based on the Shares and Units subject to the Awards at the time of grant,
regardless of when the Awards become exercisable. Subject to the provisions of
subsection 5.4, a Participant's "Individual Limit" shall be 500,000 Shares or
500,000 Units, or any combination of the foregoing.

      5.6. Limitation on Grant of Awards. Notwithstanding any provision of the
Plan to the contrary, in no event shall an Award be granted under the Plan if
the granting of such Award may, in the determination of the REIT Committee,
cause the REIT to lose its status as a real estate investment trust under
section 856 of the Code and applicable regulations thereunder.

      5.7. Change in Control. In the event of a Change in Control of the REIT
(as defined below), all Options and related Awards which have not otherwise
expired shall become immediately exercisable and all other Awards shall become
fully vested. For purposes of the Plan, a "Change in Control" means the
happening of any of the following:

      (a)   the shareholders of the REIT approve a definitive agreement to merge
            the REIT into or consolidate the REIT with another entity, sell or
            otherwise dispose of all or substantially all of its assets or adopt
            a plan of liquidation, provided, however, that a Change in Control
            shall not be deemed to have occurred by reason of a transaction, or
            a substantially concurrent or otherwise related series of
            transactions, upon the completion of which 50% or more of the
            beneficial ownership of the voting power of the REIT, the surviving
            corporation or corporation directly or indirectly controlling the
            REIT or the surviving corporation, as the case may be, is held by
            the same persons (as defined below) (although not necessarily in the
            same proportion) as held the beneficial ownership of the voting
            power of the REIT immediately prior to the transaction or the
            substantially concurrent or otherwise related series of
            transactions, except that upon the completion thereof, employees or
            employee benefit plans of the REIT may be a new holder of such
            beneficial ownership; provided, further, that any transaction
            described in this paragraph (a) with an "Affiliate" of the REIT (as
            defined in the Securities Exchange Act of 1934, as amended (the
            "Exchange Act")) shall not be treated as a Change in Control; or


                                       9

      (b)   the "beneficial ownership" (as defined in Rule 13d-3 under the
            Exchange Act) of securities representing 25% or more of the combined
            voting power of the REIT is acquired, other than from the REIT, by
            any "person" as defined in Sections 13(d) and 14(d) of the Exchange
            Act (other than any trustee or other fiduciary holding securities
            under an employee benefit or other similar stock plan of the REIT);
            or

      (c)   at any time during any period of two consecutive years, individuals
            who at the beginning of such period were members of the Board cease
            for any reason to constitute at least a majority thereof (unless the
            election, or the nomination for election by the REIT's shareholders,
            of each new trustee was approved by a vote of at least two-thirds of
            the trustees still in office at the time of such election or
            nomination who were trustees at the beginning of such period).

      5.8. Limit on Distribution. Distribution of Shares or Units under the Plan
shall be subject to the following:

      (a)   Notwithstanding any other provision of the Plan, the REIT shall have
            no liability to deliver any Shares or Units under the Plan unless
            such delivery would comply with all applicable laws and the
            applicable requirements of any securities exchange or similar
            entity.

      (b)   In the case of a Participant who is subject to Section 16(a) and
            16(b) of the Exchange Act, the REIT Committee may, at any time, add
            such conditions and limitations to any Award to such Participant, or
            any feature of any such Award, as the REIT Committee, in its sole
            discretion, deems necessary or desirable to comply with Section
            16(a) or 16(b) and the rules and regulations thereunder or to obtain
            any exemption therefrom.

      (c)   To the extent that the Plan provides for issuance of certificates to
            reflect the transfer of Shares or Units, the transfer of such Shares
            or Units may be effected on a non-certificated basis, to the extent
            not prohibited by applicable law or the rules of any stock exchange.

      5.9. Performance-Based Compensation. To the extent that the REIT Committee
determines that it is necessary or desirable to conform any Awards under the
Plan with the requirements applicable to "Performance-Based Compensation", as
that term is used in Code section 162(m)(4)(C), it may, at or prior to the time
an Award is granted, take such steps and impose such restrictions with respect
to such Award as it determines to be necessary to satisfy such requirements
including, without limitation:

      (a)   The establishment of performance goals that must be satisfied prior
            to the payment or distribution of benefits under such


                                       10
<PAGE>

            Awards.

      (b)   The submission of such Awards and performance goals to the REIT's
            shareholders for approval and making the receipt of benefits under
            such Awards contingent on receipt of such approval.

      (c)   Providing that no payment or distribution be made under such Awards
            unless the REIT Committee certifies that the goals and the
            applicable terms of the Plan and Agreement reflecting the Awards
            have been satisfied.

To the extent that the REIT Committee determines that the foregoing requirements
relating to Performance-Based Compensation do not apply to Awards under the Plan
because the Awards constitute Options, the REIT Committee may, at the time the
Award is granted, conform the Awards to alternative methods of satisfying the
requirements applicable to Performance-Based Compensation.

      5.10. Withholding. All Awards and other payments under the Plan are
subject to withholding of all applicable taxes, which withholding obligations
may be satisfied, with the consent of the REIT Committee, through the surrender
of Shares which the Participant already owns or to which a Participant is
otherwise entitled under the Plan; provided, however, previously-owned Shares
that have been held by the Participant less than six months or Shares to which
the Participant is entitled under the Plan may only be used to satisfy the
minimum tax withholding required by applicable law.

      5.11. Transferability. Awards under the Plan are not transferable except
as designated by the Participant by will or by the laws of descent and
distribution. To the extent that the Participant who receives an Award under the
Plan has the right to exercise such Award, the Award may be exercised during the
lifetime of the Participant only by the Participant. Notwithstanding the
foregoing provisions of this subsection, the REIT Committee may permit Awards
under the Plan to be transferred to or for the benefit of the Participant's
family (including, without limitation, to a trust or partnership for the benefit
of a Participant's family), subject to such limits as the REIT Committee may
establish.

      5.12. Notices. Any notice or document required to be filed with the
granting Committee under the Plan will be properly filed if delivered or mailed
by registered mail, postage prepaid, to such Committee, in care of the REIT or
the Management Company, as applicable, at its principal executive offices. Each
Committee may, by advance written notice to affected persons, revise such notice
procedure from time to time. Any notice required under the Plan (other than a
notice of election) may be waived by the person entitled to notice.

      5.13. Form and Time of Elections. Unless otherwise specified herein, each
election required or permitted to be made by any Participant or other person
entitled to benefits under the Plan, and any permitted modification or
revocation thereof, shall be in writing filed with the applicable Committee at


                                       11
<PAGE>

such times, in such form, and subject to such restrictions and limitations, not
inconsistent with the terms of the Plan, as the Committee shall require.

      5.14. Agreement with REIT or Related Company. At the time of an Award to a
Participant under the Plan, the granting Committee may require a Participant to
enter into an agreement with the REIT or the Management Company, as applicable
(the "Agreement"), in a form specified by the granting Committee, agreeing to
the terms and conditions of the Plan and to such additional terms and
conditions, not inconsistent with the Plan, as the granting Committee may, in
its sole discretion, prescribe.

      5.15. Limitation of Implied Rights.

      (a)   Neither a Participant nor any other person shall, by reason of the
            Plan, acquire any right in or title to any assets, funds or property
            of the REIT or any Related Company whatsoever, including, without
            limitation, any specific funds, assets, or other property which the
            REIT or any Related Company, in its sole discretion, may set aside
            in anticipation of a liability under the Plan. A Participant shall
            have only a contractual right to the amounts, if any, payable under
            the Plan, unsecured by any assets of the REIT and any Related
            Company. Nothing contained in the Plan shall constitute a guarantee
            by the REIT or any Related Company that the assets of such companies
            shall be sufficient to pay any benefits to any person.

      (b)   The Plan does not constitute a contract of employment, and selection
            as a Participant will not give any employee the right to be retained
            in the employ of the REIT or any Related Company, nor any right or
            claim to any benefit under the Plan, unless such right or claim has
            specifically accrued under the terms of the Plan. Except as
            otherwise provided in the Plan, no Award under the Plan shall confer
            upon the holder thereof any right as a shareholder of the REIT or as
            a holder of interests in the Partnership prior to the date on which
            he fulfills all service requirements and other conditions for
            receipt of such rights and Shares or Units are registered in his
            name.

      5.16. Evidence. Evidence required of anyone under the Plan may be by
certificate, affidavit, document or other information which the person acting on
it considers pertinent and reliable, and signed, made or presented by the proper
party or parties.

      5.17. Action by REIT or Related Company. Any action required or permitted
to be taken by the REIT or any Related Company shall be by resolution of its
board of trustees or directors, as applicable, or by action of one or more
members of the board (including a committee of the board) who are duly
authorized to act for the board or (except to the extent prohibited by
applicable law or the rules of any stock exchange) by a duly authorized officer
of the REIT.


                                       12

      5.18. Gender and Number. Where the context admits, words in any gender
shall include any other gender, words in the singular shall include the plural
and the plural shall include the singular.

      5.19. Applicable Law. The provisions of the Plan shall be construed in
accordance with the laws of the State of Maryland, without giving effect to
choice of law principles.

                                    SECTION 6

                                   COMMITTEES

      6.1. Administration. The authority to control and manage the operation and
administration of the Plan shall be vested in a REIT Committee and a Management
Company Committee (the "Committees") in accordance with this Section 6.

      6.2. Selection of REIT Committee. So long as the REIT is subject to
Section 16 of the Exchange Act, the REIT Committee shall be selected by the
Board and shall consist of not fewer than two members of the Board or such
greater number as may be required for compliance with Rule 16b-3 issued under
the Exchange Act.

      6.3. Powers of Committees. The authority to manage and control the
operation and administration of the Plan shall be vested in the Committees,
subject to the following:

      (a)   Subject to the provisions of the Plan, the REIT Committee will have
            the authority and discretion to grant Share Options and Unit Options
            and Dividend and Distribution Equivalent Unit rights to individuals
            who, at the time of grant, perform services for the REIT or the
            Partnership, or who are officers, trustees, directors or other
            persons subject to Section 16(a) of the Exchange Act with respect to
            the REIT. The Management Company Committee shall have sole and
            exclusive authority to grant Share Options and Unit Options and
            Dividend and Distribution Equivalent Unit rights to persons who, at
            the time of grant, perform services for the Management Company and
            are not officers, trustees, directors or other persons subject to
            Section 16(a) of the Exchange Act with respect to the REIT. Each
            Committee shall have the authority to determine the time or times of
            receipt, to determine the types of Awards and the number of Shares
            or Units covered by the Awards, to establish the terms, conditions,
            performance criteria, restrictions, and other provisions of such
            Awards, and to cancel or suspend Awards. In making such Award
            determinations, the granting Committee may take into account the
            nature of services rendered by the respective individual, the
            individual's present and potential contribution to the REIT's
            success and such other


                                       13
<PAGE>

            factors as the granting Committee deems relevant.

      (b)   Subject to the provisions of the Plan, the REIT Committee will have
            the authority and discretion to determine the extent to which Awards
            under the Plan will be structured to conform to the requirements
            applicable to Performance-Based Compensation, and to take such
            action, establish such procedures, and impose such restrictions at
            the time such Awards are granted as the REIT Committee determines to
            be necessary or appropriate to conform to such requirements.

      (c)   Subject to the provisions of the Plan, the REIT Committee will have
            the authority and discretion to interpret the Plan, to establish,
            amend and rescind any rules and regulations relating to the Plan, to
            determine the terms and provisions of any agreements made pursuant
            to the Plan and to make all other determinations that may be
            necessary or advisable for the administration of the Plan.

      (d)   Any interpretation of the Plan by a Committee and any decision made
            by it under the Plan is final and binding on all persons.

      (e)   Except as otherwise expressly provided in the Plan, where a
            Committee is authorized to make a determination with respect to any
            Award, such determination shall be made at the time the Award is
            made, except that the granting Committee may reserve the authority
            to have such determination made by the granting Committee in the
            future (but only if such reservation is made at the time the Award
            is granted and is expressly stated in the Agreement reflecting the
            Award).

      6.4. Delegation by Committee. Except to the extent prohibited by
applicable law or the rules of any stock exchange or NASDAQ (if appropriate), a
Committee may allocate all or any portion of its responsibilities and powers to
any one or more of its members and may delegate all or any part of its
responsibilities and powers to any person or persons selected by it. Any such
allocation or delegation may be revoked by the Committee at any time.

      6.5. Information to be Furnished to Committees. The REIT and Related
Companies shall furnish each Committee such data and information as may be
required for it to discharge its duties. The records of the REIT and Related
Companies as to an employee's or Participant's employment (or other provision of
services), termination of employment (or cessation of the provision of
services), leave of absence, reemployment and compensation shall be conclusive
on all persons unless determined to be incorrect. Participants and other persons
entitled to benefits under the Plan must furnish the Committees such evidence,
data or information as the Committees consider desirable to carry out the terms
of the Plan.

      6.6. Liability and Indemnification of Committees. No member or


                                       14
<PAGE>

authorized delegate of either Committee shall be liable to any person for any
action taken or omitted in connection with the administration of the Plan unless
attributable to his own fraud or willful misconduct; nor shall the REIT or any
Related Company be liable to any person for any such action unless attributable
to fraud or willful misconduct on the part of a trustee or employee of the REIT
or Related Company. Each Committee, the individual members thereof, and persons
acting as the authorized delegates of the Committee under the Plan, shall be
indemnified by the REIT against any and all liabilities, losses, costs and
expenses (including legal fees and expenses) of whatsoever kind and nature which
may be imposed on, incurred by or asserted against the Committee or its members
or authorized delegates by reason of the performance of a Committee function if
the Committee or its members or authorized delegates did not act dishonestly or
in willful violation of the law or regulation under which such liability, loss,
cost or expense arises. This indemnification shall not duplicate but may
supplement any coverage available under any applicable insurance.

                                    SECTION 7

                            AMENDMENT AND TERMINATION

      The Board may, at any time, amend or terminate the Plan, provided that,
subject to subsection 5.4 (relating to certain adjustments to shares), no
amendment or termination may materially adversely affect the rights of any
Participant or beneficiary under any Award made under the Plan prior to the date
such amendment is adopted by the Board.
