ITEM 1.  BUSINESS
         --------

CABOT TRUST

Cabot Industrial Trust ("Cabot Trust") was organized on October 10, 1997 as a
Maryland real estate investment trust to continue and expand the national
industrial real estate business of Cabot Partners Limited Partnership ("Cabot
Partners").  Cabot Trust is organized in what is commonly referred to as an
umbrella partnership, or "UPREIT" structure, meaning that its properties are
held and its business is conducted primarily through a limited partnership,
Cabot Industrial Properties, L.P. ("Cabot L.P."), of which Cabot Trust is the
sole general partner.  At December 31, 1998, Cabot Trust held a 42.7%
partnership interest in Cabot L.P.  The balance of the partnership interests in
Cabot L.P. at that date were primarily held by various investors who had
contributed properties 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 and 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, 1998, Cabot L.P. owned a geographically
diversified portfolio of 206 industrial properties having an aggregate of
approximately 28 million rentable square feet, approximately 97% of which space
was leased to 414 tenants.  The properties are located in 21 states in each of
the five principal regions (West, Midwest, Northeast, Southeast, and Southwest)
of the United States.  As of December 31, 1998, no single tenant accounted for
more than 4.0% of Cabot L.P.'s total annualized base rent. Since December 31,
1998, and through March 8, 1999, Cabot L.P. has acquired two industrial
properties containing approximately 139,000 square feet and has also contracted
to purchase 33 additional industrial properties containing approximately
1,822,000 square feet.

Cabot Trust's goal is to be the preeminent national real estate company focused
on serving a variety of industrial space users. As of December 31, 1998, Cabot
Trust has a significant market presence across the United States, with
properties in a total of 21 markets (18 of which Cabot Trust has identified as
principal targeted markets), including ten markets with 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 Trust 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 in markets across the country.

Cabot Trust 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).

Cabot Trust's 18 principal targeted markets and its property holdings in each
are indicated below. See "Item 2. Properties".
                                  ----------  

                                       1
<PAGE>
 
In addition to acquiring existing industrial properties, Cabot Trust is engaged
in the development and construction of new properties. Its development
activities are conducted through relationships with local builders selected by
Cabot Trust. As of December 31, 1998, Cabot Trust had approved 10 development
projects with total projected development costs of approximately $78 million.
Cabot Trust currently has under active consideration 4 additional projects with
projected development costs of approximately $60 million. The projects are
located in nine of Cabot Trust's existing submarkets and involve construction of
each of Cabot Trust's principal property types.

Cabot Trust intends to be taxed as a real estate investment trust ("REIT") under
the Internal Revenue Code of 1986 (the "Code") as amended beginning with its
fiscal year ended December 31, 1998. As a REIT, Cabot Trust will not generally
be subject to Federal income tax to the extent it distributes its taxable income
to its shareholders.

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

FORMATION TRANSACTIONS; ORGANIZATIONAL STRUCTURE

Cabot Trust completed an initial public offering of 8,625,000 common shares of
beneficial interest ("Common Shares") in February 1998 and concurrently
completed 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.  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. 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.

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 were
contributed to Cabot L.P. in exchange for a corresponding number of Units of
partnership interest. The net proceeds of future share issuances by Cabot Trust
will also be required to be contributed to Cabot L.P. in exchange for units of
partnership interest therein.

As the general partner of Cabot L.P., Cabot Trust has the exclusive power under
the agreement of limited partnership of Cabot L.P. to manage and conduct the
business of Cabot L.P.  The Board of Trustees of Cabot Trust manages the affairs
of Cabot Trust by directing the affairs of Cabot L.P.

Beginning on February 4, 1999, the original Unitholders in Cabot L.P., who were
contributing investors in the Formation Transactions, have the right to convert
their Units to Common Shares. 

                                       2
<PAGE>
 
Cabot Trust expects that substantially all tax-exempt unitholders will convert
their interest to Common Shares (approximately 22 million shares), which would
have the effect of reducing the minority interest ownership in Cabot L.P. to
approximately 7%. Cabot Trust has filed a registration statement with the SEC,
which will permit the shareholders to sell their Common Shares in the public
market.

BUSINESS STRATEGIES

Cabot Trust's fundamental business objectives are to maximize the total return
to its shareholders through growth in its cash available for distribution per
Common Share and in the value of its portfolio of industrial properties and
operations.  Cabot Trust 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.

Leveraging Substantial National Market Presence
Cabot Trust believes that maintaining and expanding its market presence in its
18 principal targeted markets across the country is an important factor in
achieving future growth and its targeted returns on investment.

Cabot Trust believes that its substantial presence in its principal markets
provide significant strategic advantages.  Foremost among these advantages is
that Cabot Trust is well positioned to market its industrial space to national
companies and third-party logistics companies who have space requirements in
multiple markets.  Cabot Trust has a national tenant marketing program that
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
its 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 Trust
serves 23 tenants in multiple properties.  These tenants accounted for
approximately 21% of Cabot Trust's Annualized Net Rents as of December 31, 1998.

Cabot Trust 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 other
local market participants serve as sources of information and potential tenant
referrals.  In addition, larger inventories increase Cabot Trust'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 Trust 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 Trust believes that its strategy of offering a variety of industrial
property types provides complementary benefits in meeting Cabot Trust's growth
objectives. Offering a broad spectrum of industrial property types and Cabot
Trust's size and professional management capability enable it 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 Trust to capture a larger
share of the growth in its chosen industrial property markets. Cabot Trust's
strategy of offering diverse industrial property types also enables Cabot Trust
to pursue opportunities as they arise across its tenants mix by responding to
shifts in demand at different stages of the economic cycle.

GROWTH STRATEGIES

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

Acquisitions
Cabot Trust 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 the period from
the completion of the Offerings in February 1998 through December 31, 1998,
Cabot Trust acquired 84 properties, consisting of 9.6 million rentable square
feet in 12 targeted markets, for $426.2 million in 41 separate transactions.  As
of March 8, 1999, Cabot Trust has acquired two additional properties in the
Dallas market, consisting of 139,287 rentable square feet subsequent to year
end.  In addition, Cabot Trust has entered into contracts to acquire properties
consisting of 1,821,763 rentable square feet in the New York/New Jersey,
Baltimore/Washington and Cincinnati/Northern Kentucky markets and one property
in the Minnesota market. Cabot Trust expects to complete these acquisitions by
April 1999.

     Investment Criteria
Cabot Trust follows a disciplined, value-oriented strategy in its property
acquisitions.  Cabot Trust seeks to acquire modern, cost-efficient buildings
located in key national and regional distribution centers.  Cabot Trust'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 Trust'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 Trust's research
includes extensive in-market activity by its employees, including physical site
inspections and continuing contacts with leasing brokers and other active
participants in the local markets.  Cabot Trust has compiled the results of its
extensive research over the years into a proprietary database, which it updates
periodically, covering each market and submarket in which it has invested
substantially.  The database contains computerized profiles, keyed to Cabot
Trust-prepared aerial maps of Cabot Trust's properties and each of the buildings
deemed most competitive to Cabot Trust's properties or attractive for
acquisition.  Such profiles include information regarding the building's age,
physical characteristics (including overall dimensions, clear heights and truck
court dimensions) and current tenant and lease information.

     Diversification of Industrial Property Types
To date, the majority of Cabot Trust's Properties (72% of its properties based
on Annualized Net Rents at December 31, 1998) have been bulk distribution and
multitenant distribution facilities because of the opportunities for superior
returns such properties have provided.  While Cabot Trust expects that both
types of properties will continue to be an important focus of its future
acquisition program, Cabot Trust 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 Trust
continues to increase its acquisitions of workspace properties, which
represented approximately 28% of its Properties at December 31, 1998 (based on
Annualized Net Rents).

     Relationships with Institutional Real Estate Investors
Cabot Partners' operations were 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 Trust's management with an extensive knowledge of and, Cabot Trust
believes, a favorable reputation with such investors.  Cabot Trust 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 and UPREIT Structure
Cabot Trust intends to exploit its relatively unleveraged capital structure and
substantial equity base in its acquisition and development activities.  Cabot
Trust believes that its ability to borrow using its $325 million revolving
credit acquisition facility will enhance its credibility with potential property
sellers.  Cabot Trust'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, provides an attractive alternative to a taxable cash
sale for tax-paying property owners.

Development
Cabot Trust'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 Trust 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 it pursues a development program where such
opportunities exist. Cabot Trust 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 initial overhead expenses, Cabot Trust
has begun its development activities by engaging local or regional builders with
whom it has established strong relationships. Cabot Trust intends to expand its
in-house development staff as Cabot Trust's development activities increase.

Internal Growth
Cabot Trust's primary internal growth strategy is to increase the cash flow
generated by its Properties, and from properties that it acquires in the future,
by renewing or replacing expiring leases with new leases at higher rental rates
and through rent increase provisions in its leases. In addition, Cabot Trust
intends to work 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 any newly acquired properties that
have lower occupancy levels than Cabot Trust 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 Trust 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 14.3% and 12.2% of the total Annualized Net Rent of Cabot Trust's
properties will expire in 1999 and 2000, respectively.

LEASES

Cabot Trust's properties typically are leased on a triple net basis, with
tenants paying their proportionate share of real estate taxes and operating
costs. However, some of the properties are leased at higher gross rents with
Cabot Trust being responsible for paying a stated

                                       5
<PAGE>
 
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 42% (based on Annualized Net Rent) of the leases
contain a provision providing for an automatic "stepped rent" increase of a
specified amount or percentage at a certain point or points during the term of
the lease. Substantially all of the leases of the 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
the expense reimbursements and contractual rent increases described above.

POLICIES

Business Policies
The following is a description of business policies that have been adopted by
the Cabot Trust Board of Trustees. These policies may be amended or revised from
time to time without 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 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 the Cabot L.P. or a
subsidiary may be a partner.  Cabot Trust'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 Trust'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
Common Shares.  Investments are also subject to Cabot Trust's policy not to be
treated as an investment company under the Investment Company Act of 1940.

Cabot Trust currently intends to invest primarily in existing improved
properties, but also has begun investment in development projects as well.
Future investment or development activities will not be limited to any
geographic area or product type or to a specified percentage of assets.  While
Cabot Trust intends to maintain diversity in its investments in terms of
property location, size and market, Cabot Trust 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 its investment and
development activities in a manner that is consistent with the maintenance of
its status as a REIT for federal income tax purposes.

                                       6
<PAGE>
 
While Cabot Trust's current portfolio consists of, and its business objectives
emphasize, equity investments in industrial real estate, Cabot Trust may also
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.
These may include participating or convertible mortgage loans if Cabot Trust
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 Trust 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 Trust 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 Trust 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
Trust to own interests in larger assets without unduly restricting
diversification and, therefore, add flexibility in structuring its portfolio.
Cabot Trust will not enter into a joint venture or partnership to make an
investment that would not meet its investment policies.

Financing Policies
As a general policy, Cabot Trust intends to limit its total consolidated
indebtedness incurred so that at the time any debt is incurred, Cabot Trust's
debt-to-total market capitalization ratio does not exceed 40%.  Cabot Trust's
Declaration of Trust and Bylaws do not, however, limit the amount or percentage
of indebtedness that it may incur.  Moreover, due to fluctuations in the value
of Cabot Trust's portfolio of properties over time, and since any determination
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 Trust 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 Common
Shares, growth and acquisition opportunities and other factors.  If its debt
policy were changed, Cabot Trust 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 Trust and its ability to make distributions
to shareholders.

Cabot Trust has not established any limit on the number or amount of mortgages
that may be placed on any single property or on its portfolio as a whole.

To the extent that its Board of Trustees decides to obtain additional capital,
Cabot Trust may raise such capital through offerings of its Common or Preferred
Shares or of partnership units which may include preferred Units of Cabot L.P.,
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 that
equals the number of Common Shares sold by Cabot Trust.

Cabot Trust presently anticipates that any additional 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 Trust, or any existing or new property-
owning partnership and may have full or limited recourse to all or any portion
of the assets of

                                       7
<PAGE>
 
Cabot Trust, 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.

Conflict of Interest Policies
Cabot Trust 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 shareholders.

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 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 decisions affecting the business and
assets of the 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 L.P., in its capacity as general partner, has undertaken in good
faith on behalf of

                                       8
<PAGE>
 
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.

Policies with Respect to Other Activities
Cabot Trust 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
Trust has no outstanding loans to other entities or persons, including its
officers and Trustees.  Cabot Trust has not engaged in trading, underwriting or
agency distribution or sale of securities of other issuers, nor has Cabot Trust
invested in the securities of  companies other than Cabot L.P. for the purpose
of exercising control over such companies and currently does not intend to do
so.  Cabot Trust makes and intends to continue to make investments in such a way
that it will not be treated as an investment company under the Investment
Company Act of 1940.  Its policies with respect to such activities may be
reviewed and modified or amended from time to time by the Board of Trustees
without shareholders approval.

Cabot Trust 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 determines that it is no longer in the best
interests of Cabot Trust to qualify as a REIT.

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

COMPETITION

Numerous industrial properties compete with Cabot Trust'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 will have a
material effect on Cabot Trust'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 Trust's properties.

In addition, the industrial real estate 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. This has resulted in increased competition in acquiring attractive
industrial properties. Accordingly, it is possible that Cabot Trust may not be
able to meet its targeted level of property acquisitions and developments due to
such competition or other factors which may have an adverse effect on Cabot
Trust's expected growth in Funds from Operations ("FFO").  Cabot Trust may be
competing with others that have greater resources than Cabot Trust and whose
officers and directors have more experience than Cabot Trust's officers and
trustees.

                                       9

INSURANCE

Cabot Trust carries commercial general liability insurance, standard "all-risk"
property insurance, flood, earthquake and rental loss insurance with respect to
the 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 Trust could lose the capital
invested in a property, as well as the anticipated future revenue from that
property, and Cabot Trust 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 Trust's current policy is to obtain
earthquake insurance if available at acceptable cost. As of December 31, 1998,
all of our 50 properties located in California are covered by earthquake
insurance in amounts believed by management to be reasonable. At December 31,
1998, seismic upgrading had been completed on eleven of the California
properties and seismic upgrading is expected to be completed on ten additional
California properties by September 30, 1999. Cabot Trust currently maintains
blanket earthquake insurance coverage for all properties located outside
California in amounts Cabot Trust 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 Trust 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.

                                       10
<PAGE>
 
The purpose of Phase I ESAs is to identify potential sources of contamination
for which Cabot Trust may be responsible and to assess the status of
environmental regulatory compliance. The earliest of the Phase I ESAs for Cabot
Trust's properties were obtained in 1988 and Phase I ESAs on approximately 19%
of the properties owned as of December 31, 1998, 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 Trust's properties have not revealed any
environmental liability that Cabot Trust believes would have a material adverse
effect on its business, assets or results of operations, nor is Cabot Trust
aware of any such material environmental liability.  It is possible, however,
that the Phase I ESAs relating to the 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 Trust.


CABOT ADVISORS

Cabot Advisors provides investment advisory and asset management services to the
former clients of Cabot Partners which 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 Advisors will not
provide services relating to any industrial real estate acquisition or
development activities that would conflict with Cabot Trust's own acquisition
and development activities. Cabot Trust 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, 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 dividends 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.


EMPLOYEES

At December 31, 1998, Cabot L.P. and Cabot Advisors employed 61 persons, none of
whom are represented by any collective bargaining organization.  Cabot Trust
believes it has good relations with its employees.

ITEM 2.   PROPERTIES
          ----------

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

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 predominately 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 the following information related to the
Properties as of December 31, 1998: (i) the name and location of the Properties,
identified by each of Cabot Trust's 18 principal targeted markets; (ii) the year
each property was built or substantially renovated; (iii) the number of
properties at each location; (iv) the rentable square feet at each location; (v)
the percent of the rentable square feet of each property that is currently
leased; (vi) the annualized net rent for the tenants leasing each property and
(vii) the annualized net rent per leased square foot.

Item 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS
         ---------------------------------------------------------------------
 
Cabot Trust's common shares began trading on the New York Stock Exchange
("NYSE") on January 30, 1998, under the symbol "CTR." The following table sets
forth the high and low sales prices per share as reported on the New York Stock
Exchange Composite Tape and the distributions paid on the Common Shares for the
periods indicated.


1998:                                      High      Low         Distributions
- -----                                      ----      ---         -------------

  Second Quarter                          25.13     19.81             .325
  Third Quarter                           22.19     17.56             .325

1999:
- -----
  First Quarter (through March 8, 1999)   20.44     18.25              --

On March 8, 1999, Cabot Trust had 18,636,552 Common Shares outstanding held of

The actual operating cash flow that Cabot Trust will realize and the amount
available for distributions to shareholders will be affected by a number of
factors, including the revenues received from the properties, the distributions
it receives from Cabot L.P., the operating expenses of Cabot L.P. and Cabot
Trust, the interest expense on borrowings and capital expenditures. Future
distributions by Cabot Trust will be at the discretion of the Board of Trustees
and will depend on the actual FFO of Cabot Trust, its financial condition,
capital requirements, the annual income distribution requirements under the REIT
provisions of the Code and such other factors as the Board of Trustees deems
relevant. In 1998, 100 percent of Cabot Trust's distributions to shareholders
were taxable as ordinary income.

which may cause actual results to differ materially from what is expressed
herein. Capital and credit market conditions which affect Cabot Trust's cost of

including tenant reimbursements of $13.4 million. Total rental revenue of $74.4
million was generated by the 121 properties still owned as of December 31, 1998,
which were also owned as of February 4, 1998, as a result of the Formation
Transactions (the "Baseline Properties"), $27.1 million of rental revenue was
generated by the 84 properties acquired subsequent to February 4, 1998, and the
development property placed into service in 1998 and the remaining $864,000 of
rental revenue relates to a property that was sold by Cabot Trust during 1998.
The ratio of tenant reimbursements to operating and real estate tax expenses was
approximately 73%. Depreciation and amortization related to real estate
investments totaled $20.9 million for the year ended December 31, 1998.

Interest and other income included $231,000 of earnings from Cabot Advisors. The
remainder of such income consists primarily of interest income earned on Cabot
Trust's invested cash balances. Interest expense represents $1.8 million of
interest incurred on $48.2 million of mortgage indebtedness outstanding and also
includes interest expense of $5.2 million related to borrowings under the
Acquisition Facility, net of amounts capitalized to development projects.

CABOT PARTNERS

Years Ended December 31, 1997 and 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 6.9%, of the increase. The remainder of the increase was primarily
due to higher professional services fees. General and administrative expenses as
a percent 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

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 of shares. All of the Common Shares were sold at a price of
$20.00 per share. The proceeds from the Offerings, net of offering costs, were
$176.3 million.

Cabot Trust 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 Trust may also consider preferred and common equity financing
when such financing is available on attractive terms.

In March 1998, Cabot L.P. executed the Acquisition Facility, which is a 
$325 million unsecured revolving line of credit, with Morgan Guaranty Trust
Company of New York as lead agent to 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, minimum unencumbered assets to
unsecured debt ratios and other limitations. Cabot Trust believes cash flow from
operations not distributed to shareholders and unitholders will be sufficient to
cover tenant allowances and costs associated with renewal or replacement of
current tenants as their leases expire and recurring non-incremental revenue
generating capital expenditures.

In the normal course of operations, as of March 8, 1999, Cabot Trust has
purchased approximately $5.4 million of real estate assets in 1999 and has
commitments to purchase $71.2 million of additional real estate assets.  The
completed real estate assets acquisitions were primarily funded through
Acquisition Facility borrowings.

As of December 31, 1998, Cabot L.P. had $48.2 million of fixed rate debt secured
by properties, $200.0 million of unsecured variable rate borrowings under its
Acquisition Facility and a 22% debt-to-total market capitalization ratio.  The
debt-to-total market capitalization ratio is calculated based on Cabot Trust's
total consolidated debt as a percentage of the market value of outstanding
Common Shares and Units (not held by Cabot Trust) plus total debt.  In addition,
in February 1999, Cabot Trust borrowed $87.6 million, secured by properties, the
proceeds of which borrowing were used to repay a portion of the outstanding
balance under the Acquisition Facility.

Cabot Trust entered into an interest rate collar arrangement relating to its
LIBOR-based Acquisition Facility for a notional amount of $140 million for the
period January 1, 1999, through February 15, 1999. The arrangement is intended
to result in limiting the variable LIBOR component of Cabot Trust's interest
cost on an equivalent amount of borrowings to the range of 5.05% to 6.25% per
annum. Cabot Trust has also entered into an interest rate hedge transaction
involving the future sale of $100 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 million with a maturity of 10 years. Based on the rate
for 10-year Treasury Securities as of close of business on March 8, 1999, the
hedge transaction would be settled by Cabot Trust paying $2.1 million, which
would have the effect of increasing Cabot Trust's borrowing rate on $100 million
of anticipated borrowings by approximately 0.2%. If an offering of the size and
maturity contemplated is not completed by the time of, or shortly after, the
March 31, 1999 settlement date of the hedge transaction, or if for any other
reason the transaction is determined no longer to qualify for hedge accounting
treatment, Cabot Trust would be required to record an expense equal to the fair
value of the instrument (or the remaining unmatched portion thereof) as of the
earlier of the termination date of the instrument or the date of such
determination. As of March 8, 1999, the fair value of the instrument and,
accordingly, the expense that Cabot Trust would have been required to record was
$2.1 million. Such amount changes, in amounts that may be material, as the
market price and the related yield (5.261% at March 8, 1999) on 10-year Treasury
Securities varies.

Cash and cash equivalents totaled $2.3 million at December 31, 1998.  This was
the result of $78.7 million of cash generated from operating activities and
$322.4 million provided by financing activities, reduced by $398.8 million used
for investing activities.

Year 2000

Cabot Trust has assessed its Year 2000 readiness with respect to its internal
accounting and information systems. Cabot Trust also has contacted its
significant vendors, including banks and software providers, to determine
whether those vendors are satisfactorily addressing the Year 2000 problem with
respect to the products and services they provide to Cabot Trust. No significant
issues or costs of remediation have been identified with respect to such systems
or vendors. Cabot Trust has also completed its review of its other internal
systems (consisting primarily of property-related systems, such as elevators and
heating, ventilation, and air conditioning systems) and has developed a Year
2000 remedial plan to address issues identified in such review, none of which
are considered by Cabot Trust to be material. Remediation costs to date have not
been material, and Cabot Trust does not expect any significant issues or
remediation costs as a result of completion of its remedial plan due to the
relatively uncomplicated nature of its real estate assets (industrial
properties) and the general nature of its leases, which in many instances
provide for the reimbursement of costs from its tenants. Cabot Trust believes
that there will be no direct material effects on its operating performance or
results of operations from the Year 2000 problem as it relates to Cabot Trust's
internal systems and significant vendors. Cabot Trust further believes that
adequate alternative service providers will be available to it if any of its
vendors experience unexpected difficulties as a result of Year 2000 systems
failures and, accordingly, has not established any specific contingency plans in
this regard. It is not possible to quantify any potential indirect effects that
may result from the lack of Year 2000 readiness on the part of third parties,
including tenants, with whom Cabot Trust conducts its business.


INFLATION

Substantially all of the leases of the 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 off-set, in part, by
these expense reimbursements and contractual rent increases.


ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
          ----------------------------------------------------------

Cabot Trust is exposed to market risk, primarily from changes in interest rates.
To manage the volatility relating to interest rate risk exposure, Cabot Trust
enters into interest rate protection agreements which are designed to limit
Cabot Trust's exposure to interest rate risk. Cabot Trust does not hold or issue
derivative financial instruments for trading purposes.

Certain of Cabot Trust's long-term obligations and interest rate protection
agreements are sensitive to changes in interest rates. A hypothetical 100 basis
point increase in interest rates would increase the interest expense on
outstanding borrowings under the Acquisition Facility by approximately $2
million per year, based on the balance outstanding as of December 31, 1998.

Cabot Trust has entered into a treasury rate lock transaction to hedge a future
anticipated debt issuance. The settlement cost or benefit of this arrangement
will be reflected as an adjustment to interest expense over the life of the
anticipated debt issuance, if this transaction continues to qualify for hedge

                                       26

accounting treatment. Otherwise, the amount paid or received by Cabot Trust to
settle this transaction would result in a current period loss or gain recorded
in Cabot Trust's consolidated statement of operations. Based on the settlement
value of the transaction as of March 8, 1999, Cabot Trust would make a payment
of $2.1 million and would record a current period loss in that amount. A
hypothetical 10 basis point increase or decrease in interest rates would result
in an increase or decrease in the amount payable under this hedge transaction
(compared to the value at December 31, 1998) of approximately $800,000.

                   Report of Independent Public Accountants


To the Board of Trustees
 of Cabot Industrial Trust:


We have audited the accompanying consolidated balance sheet of Cabot Industrial
Trust and subsidiaries (Cabot Trust), a Maryland real estate investment trust,
as of December 31, 1998 and 1997, and the related consolidated statements of
operations, shareholders' equity and cash flows for the year ended December 31,
1998 (Note 1). These financial statements are the responsibility of Cabot
Trust'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
Trust and subsidiaries as of December 31, 1998 and 1997, and the results of
their operations and their cash flows for the year ended December 31, 1998, 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.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31,1998

1.  GENERAL

Organization
Cabot Industrial Trust (Cabot Trust), a Maryland real estate investment trust,
was formed on October 10, 1997.  Cabot Trust is the managing general partner of
a limited partnership, Cabot Industrial Properties, L.P. (Cabot L.P.), and
conducts substantially all of its business through Cabot L.P.  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., and
therefore Cabot Trust consolidates the financial results of Cabot L.P. for
financial reporting purposes.

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 expects to qualify as a real
estate investment trust (a REIT) for federal income tax purposes.

Since Cabot Trust 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.

Initial Capitalization
The initial capitalization of Cabot Trust consisted of 50 Common Shares of
beneficial interest, par value $.01 per share (Common Shares), issued for a
total consideration of $1,000. In connection with the Formation Transactions and
Offerings (described below), Cabot Trust issued an additional 18,586,714 Common
Shares.

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 Units in Cabot L.P. that may,
subject to certain restrictions, be exchanged for common shares of Cabot Trust
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 general partnership Units in Cabot L.P.
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, 1998, Cabot Trust owned 42.7% of Cabot L.P.  The remaining
57.3%, which is owned by investors that elected to receive Operating Partnership
Units, is considered minority interest.

1.  GENERAL (CONTINUED)

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, the Offerings).  Cabot Trust contributed the net proceeds of the
Offerings to 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
Trust, Cabot L.P. and their subsidiaries over which they exercise control.  The
ownership interest in Cabot L.P. which is not owned by Cabot Trust is reflected
as Minority Interest.  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 Trust'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
will be 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 1998.

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

                               DECEMBER 31,1998

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Capitalization of Costs
Cabot Trust 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 sheet are
presented net of accumulated amortization totaling $3,487,000 and $466,000,
respectively, as of December 31, 1998.

Investment in Cabot Advisors
Cabot Trust's investment in Cabot Advisors is accounted for using the equity
method.  Under the equity method of accounting, Cabot Trust'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 Trust 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 Trust 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.

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". The new statement is effective for fiscal
years beginning after June 15, 1999; 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 Trust 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 due to its relatively limited use of
derivative instruments.


3.   ACQUISITIONS OF REAL ESTATE INVESTMENTS

In accordance with generally accepted accounting principles, Cabot Trust 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

</TABLE>

Subsequent to the Formation Transactions, Cabot Trust acquired 84 properties
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.


4.   DEBT FACILITIES

The Acquisition Facility
On March 16, 1998, Cabot L.P. entered into a $325 million unsecured revolving
line of credit (the  Acquisition  Facility).   The  Acquisition  Facility
matures on  March  16,  2001,  and  the  interest rate ranges from LIBOR plus 75
basis points to LIBOR plus 125 basis points depending on Cabot L.P.'s loan-to-
value ratio.  At December 31, 1998, outstanding borrowings under the Acquisition
Facility were $200 million and the interest rate was LIBOR plus 100 basis
points, or 6.60%.  The weighted average coupon interest rate on the Acquisition
Facility was 6.58% for the year ended December 31, 1998, including the effect of
the interest rate collar arrangements described below.  The Acquisition Facility
is intended to be used to acquire and develop properties and for working capital
purposes.

4.   DEBT FACILITIES (CONTINUED

Cabot Trust has entered into an interest rate collar arrangement relating to its
LIBOR-based Acquisition Facility for a notional amount of $140 million for the
period from January 1, 1999, through February 15, 1999.  The arrangement is
intended to result in limiting the LIBOR component of Cabot Trust's interest
rate on an equivalent amount of borrowings to the range of 5.05% to 6.25% per
annum.  Similar arrangements in effect during 1998 resulted in interest expense
of $47,000.  Cabot Trust has also entered into an interest rate hedge
transaction, which expires on March 31, 1999, involving the future sale of $100
million of Treasury Securities based on a rate of approximately 5.54% for such
securities in anticipation of a future debt issuance with a maturity of 10
years. (See Notes 9 and 13.)

Mortgage Loans
Cabot Trust assumed certain loans in connection with the Formation Transactions
and has assumed certain loans in conjunction with subsequent real estate
acquisitions (the Mortgage Loans).  The Mortgage Loans bear interest at annual
coupon rates ranging from 7.95% to 9.67% and are secured by certain of Cabot
Trust's properties, with a net book value of $92.6 million as of December 31,
1998.  Certain of the debt assumed in conjunction with the acquisition of
properties bears a coupon interest rate which 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 statement of
operations is adjusted based on the fair market interest rate at the date of
purchase.

Aggregate principal payments on mortgage notes payable at December 31, 1998, for
the five years ending December 31 and thereafter are as follows:

                                       (in 000's)

5.  FUTURE MINIMUM RENTS (CONTINUED)

Cabot Trust 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
Trust's minimum future rental receipts related to non-industrial properties
total $2.3 million.


6.  INCOME TAXES

Cabot Trust intends to make an election to be taxed as a REIT under Sections 856
through 860 of the Internal Revenue Code of 1986, as amended.  As a REIT, Cabot
Trust generally will not be subject to federal income tax if it distributes at
least 95% of its taxable income for each tax year to its shareholders.  REITs
are also subject to a number of organizational and operational requirements.  If
Cabot Trust fails to qualify as a REIT in any taxable year, Cabot Trust will be
subject to federal income tax (including any applicable alternative minimum tax)
on its taxable income at regular corporate tax rates.  Even if Cabot Trust
qualifies for taxation as a REIT, Cabot Trust may be subject to state and local
income tax and to federal income tax and excise tax on its undistributed income.


7.  EMPLOYEE BENEFIT PLANS

Cabot Trust has adopted the Cabot Industrial Trust Long Term Incentive Plan (the
"Plan") for the purpose of attracting and retaining highly qualified executive
officers, Trustees and employees. The Plan is administered by the Executive
Compensation Committee of the Board of Trustees, except that the Board of
Directors of Cabot Advisors or a committee thereof selects those employees of
Cabot Advisors who are eligible for awards under the Plan (in either case, the
Administrator). Officers and other employees of Cabot Trust, Cabot L.P. and
designated subsidiaries and members of the Board of Trustees 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 Plan, at December 31, 1998, authorizes the issuance of up to
4,347,500 Common Shares and Units. The number of Common Shares and Units
available may increase each January 1 to an amount equal to 10% of the aggregate
number of outstanding Common Shares and Units on such date, and therefore,
currently the Plan authorizes the issuance of up to 4,349,047 Common Shares and
Units. The Plan provides for the grant of (i) Common Share options intended to
qualify as incentive options under Section 422 of the Code, (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.

7.   EMPLOYEE BENEFIT PLANS (CONTINUED)

In connection with the grant of options under the Plan, other than options to
Non-employee 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 Plan during 1998 have ten-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 Plan). DEUs entitle an option holder to an award of
additional shares or units 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 the same vesting schedule as the
underlying option and entitle the holder to a share or unit at the earlier of
the year of exercise, or the year of expiration, of the underlying option. The
options granted in 1998 were generally awarded with DEUs, which resulted in
compensation expense of approximately $400,000.

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 Plan will be forfeited.  Any Common Shares or Units subject to an option
which is forfeited (or which expires without exercise) will again be available
for grant under the Plan.

A summary of Cabot Trust's stock option activity is as follows:

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 Trust has elected to apply APB Opinion No. 25 to account for its
stock-based compensation plans.  Accordingly, except for the distribution
equivalent units as described above, no compensation cost has been recognized
for Cabot Trust's Long Term Incentive Plan as the option prices at the date of
grant were equal to market prices.  Had compensation cost for awards in 1998
under Cabot Trust's stock-based compensation 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 Trust's net income and earnings per share would
have been as follows:

                                                           1998
- ----------------------------------------------------------------------
Net income:
  As reported                                        $ 21,766,000
  Pro forma                                            21,255,000
Basic earnings per share:
  As reported                                        $       1.17
  Pro forma                                                  1.14
Diluted earnings per share:
  As reported                                        $       1.17
  Pro forma                                                  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 of options granted was $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:

7.  Employee Benefit Plans (continued)
                                                    1998
               -----------------------------------------------
               Expected volatility                 20.66%
               Risk-free interest rate           4.52- 5.60%
               Expected life of options            7 years
               Expected dividend yield              6.2%

The Black-Scholes option-pricing model was developed for use in estimating the
fair value of traded options which 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 stock 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 stock options.

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


8. Earnings per Share

In accordance with  SFAS No. 128, "Earnings per Share", basic earnings per share
have been computed by dividing net income by the weighted average number of
shares outstanding during the period subsequent to Cabot Trust's commencement of
operations (see Note 1).

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

9.  Fair Value Of Financial Instruments

Statement of Financial Accounting Standards No. 107, "Disclosures about Fair
Value of Financial Instruments," requires Cabot Trust 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 sheet.  Cabot
Trust'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 sheet approximate fair value.

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

                                           Carrying Amount     Fair Value
- ----------------------------------------------------------------------------
                                                        (in 000's)
Long-term obligations:                             
     Mortgage loans payable                    $(48,206)        $(51,450)
 
Off-balance-sheet financial instruments:
     Interest rate protection agreements 
     (liability)                                   -            $( 6,734)

Cabot Trust's mortgage loans are at fixed rates, which in certain cases differ
from borrowing rates currently available to Cabot Trust 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.  Cabot Trust's Acquisition Facility is at a variable rate,
which results in a carrying value that approximates its fair value.  The fair
value of Cabot Trust's interest rate protection agreements is the estimated
amount that Cabot Trust would pay if it had terminated the contract as of
December 31, 1998, taking into account the change in interest rates and the
creditworthiness of the counterparties.

approximately 11 months. Cabot Trust's share of Cabot Advisors' net income is
included in Interest and Other Income in the accompanying consolidated statement
of operations.

11.  Commitments And Contingencies

Concentration of Credit Risk
Cabot Trust 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 Trust believes the risk is not significant.

Environmental
Cabot Trust, as an owner of real estate, is subject to various environmental
laws of federal and local governments.  All of Cabot Trust'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 Trust with existing laws has not
had a material adverse effect on Cabot Trust'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 Trust does not believe there is any litigation threatened
against it other than routine litigation arising out of the ordinary course of
business, some of which is expected to be covered by liability insurance, none
of which is expected to have a material adverse effect on the consolidated
operating results or financial position of Cabot Trust.

Minimum Future Lease Obligations
Minimum future lease obligations under noncancelable operating leases for each
of the next five years ending December 31 and thereafter are as follows:

         1999.................................  $  588,000
         2000.................................     596,000
         2001.................................     590,000
         Thereafter...........................        -

                                                $1,774,000

Cabot Trust incurred rental expense of $192,000 for the year ended December 31,
1998.  In addition, Cabot Advisors incurred rental expense of $181,000 for the
year ended December 31, 1998.  Cabot Trust's only significant leases are for its
office space.  The leases provide for the payment of base rent and reimbursement
of operating expenses and real estate taxes over stated base amounts.

Employment Agreements

Senior executives have entered into employment agreements with Cabot Trust and
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 $175,000 to $265,000
($1,385,000 in the aggregate in 1998) and an annual cash bonus to be determined
by the Board of Trustees or the Executive Compensation Committee. The base
annual compensation may be increased in subsequent years by action of the Board
of Trustees or 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.

Severance Agreements

On December 17, 1998, Cabot Trust's Board of Trustees approved a retention and
severance plan covering all full-time employees of Cabot Trust and its
affiliates not covered by employment agreements which will provide for six to
twenty-one months of compensation to be paid, under certain circumstances, in
the event of a change in control.

As of December 31, 1998, total costs payable under the employment and severance
agreements covering senior executives and other employees in the event of a
change in control approximated $11 million.

11.  Commitments And Contingencies (continued)

Shareholder Rights Plan 

On June 11, 1998, the Board of Trustees adopted a Rights Agreement and declared
a dividend of one preferred share purchase right (a "Right") for each
outstanding Common Share to be distributed to all holders of record of the
Common Shares on June 15, 1998. In addition, Rights will be issued with each
Common Share to be issued in the future. Each Right entitles the registered
holder to purchase one one-hundredth of a Series A Junior Participating
Preferred Share for an exercise price of $85, subject to adjustment as provided
in the Rights Agreement. The Rights will generally be exercisable only if a
person or group acquires or announces a tender offer for 15% or more of the
Common Shares. Under certain circumstances, upon a shareholder acquisition of
15% or more of the Common Shares, each Right will entitle the holder to
purchase, at the Right's then-current exercise price, a number of Common Shares
having a market value of twice the Right's exercise price. The acquisition of
Cabot Trust pursuant to certain mergers or other business transactions will
entitle each holder of a Right to purchase, at the Right's then-current exercise
price, a number of the acquiring company's common shares having a market value
at that time equal to twice the Right's exercise price. The Rights held by
certain 15% shareholders will not be exercisable. The Rights will expire on June
11, 2008, unless the expiration date of the Rights is extended, and the Rights
are subject to redemption at a price of $0.01 per Right under certain
circumstances.

13.  Subsequent Events

In February 1999, Cabot L.P. borrowed $87.6 million secured by properties with a
net book value of approximately $130 million. The borrowing has a fixed interest
rate of 7.25% per annum and a 10-year term. Monthly installments of principal
and interest are due based on a 25-year amortization rate, and any remaining
balance outstanding is due at the end of the 10-year term. This borrowing is
subject to various customary covenants.

To the Partners of
 Cabot Partners Limited Partnership:

We have audited the accompanying balance sheet 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

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 sixteen 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.

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:

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 Trust 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.

at all times prior to the release of this Mortgage:

     (a) To Borrower's knowledge, Borrower has obtained and will use
commercially reasonable efforts to maintain in full force and effect  all
certificates, licenses, permits and approvals that are issued or required (the
failure to obtain which would have a material and adverse effect on Borrower's
operation of the Property) (i) by Law, (ii) by any other entity having
jurisdiction over the Property or (iii) to be obtained by Borrower that are
necessary for the use, occupancy and operation of the Property, for the granting
of this Mortgage or for the conduct of Borrower's business on the Property in

and access to the Property for the current or contemplated use of the Property
have been completed and are and will continue to be (subject to force majeure
events) serviceable, physically open and dedicated to and accepted by the
Government for use by the public; and

     (d) All costs and expenses of labor, materials, supplies and equipment used
in the construction of the Improvements have been paid in full or will be paid
in the ordinary course of business.
 
       Section 5.2.  Maintenance of the Property.  Borrower represents and
      ------------   ---------------------------                          
warrants that as of the date hereof the Property is free from damage caused by a
Casualty, and in the event that a Casualty occurs Borrower will use commercially
reasonable efforts to cause the Property to be restored  as required with
respect to Borrower's Restoration obligations as set forth in Article VII.
Borrower will maintain (or cause to be maintained) the Property in thorough
repair and good and safe condition, suitable for the Permitted Use, including,
to the extent required under any Lease, replacing the Fixtures and Personal
Property with property at least equal in quality and condition to that being

                                       7
<PAGE>
 
additions or other structures on the Land or otherwise structurally alter the
Improvements without Lender's prior consent which may be withheld in Lender's
sole discretion, except to the extent required by a Lease approved by Lender (or
as to which Lender's approval is not required). Except as required by any Leases
approved by Lender (or as to which Lender's approval is not required), without
Lender's prior written consent, Borrower will not alter the Property in any
manner that would increase Borrower's responsibilities for compliance with Law.
The Property will be managed by a property manager satisfactory to Lender
pursuant to a management agreement satisfactory to Lender and terminable by
Borrower upon 30 days notice to the property manager. Lender, by its acceptance
of this Mortgage, acknowledges that the property manager and property management
agreement in effect as of the date hereof are acceptable to Lender.

       Section 5.3.  Change in Use.  Borrower will use and permit the use of the
      ------------   -------------                                              
Property for the Permitted Use and for no other purpose.

       Section 5.4.  Waste.  Without Lender's prior consent which may be
      ------------   -----                                              
withheld in Lender's sole discretion, Borrower will not commit or permit any
waste (including economic and non-physical waste), impairment or deterioration
of the Property or any demolition (except in connection with the build out of
any tenant space) of any of the Property, or removal of any Fixtures or Personal
Property from the Land and Improvements except to the extent any such Property
is replaced with items of equal or greater functionality or value.

       Section 5.5.  Inspection of the Property.  Subject to the rights of
      ------------   --------------------------                           
tenants under the Leases (and subtenants under Subleases), Lender has the right
to enter and inspect the Land and Improvements on reasonable prior notice,
except in the case of an emergency, when no prior notice is necessary.  Lender
has the right to engage an independent expert to review and report on Borrower's
compliance with Borrower's obligations under this Mortgage to maintain the
Property, comply with Law and refrain from waste, impairment or deterioration of
the Property and the alteration, demolition or removal of any of the Property
except as may be permitted by the provisions of this Mortgage.  If the
independent expert's report discloses material failure to comply with such
obligations or if Lender engages the independent expert after the occurrence of
an Event of Default, then the independent expert's review and report will be at
Borrower's expense, payable on demand.

       Section 5.6.  Leases and Rents.
      ------------   ---------------- 

     (a) Borrower assigns the Leases and the Rents to Lender absolutely and not
merely as additional collateral or security for the payment and performance of
the Obligations, but subject to a license back to Borrower of the right to
collect the Rents unless and until an Event of Default occurs at which time the
license will terminate automatically, all as more particularly set forth in the
Assignment, the provisions of which are incorporated in this Mortgage by
reference.

     (b) Borrower appoints Lender as Borrower's attorney-in-fact to execute
unilaterally and to record, at Lender's election, a document subordinating this
Mortgage to the Leases, 

                                       8
<PAGE>
 
provided that the subordination will not affect (i) the priority of Lender's
- --------
entitlement to Insurance Proceeds or Condemnation Awards or (ii) the priority of
this Mortgage over intervening liens or liens arising under or with respect to
the Leases and Subleases.

       Section 5.7.  Parking.  Borrower will itself (or pursuant to Lease
      ------------   -------                                             
provisions require Tenants to) provide, maintain, police and light parking areas
within the Land and Improvements, including any sidewalks, aisles, streets,
driveways, sidewalk cuts and rights-of-way to and from the adjacent public
streets, in a manner consistent with the Permitted Use and sufficient to
accommodate the greater of: (i) the number of parking spaces required by Law; or
(ii) the number of parking spaces required by the Leases and the Property
Documents.  The parking areas will be reserved and used exclusively for ingress,
egress and parking for Borrower and the tenants under the Leases and Subleases
and their respective employees, customers and invitees and otherwise in
accordance with the Leases and the Property Documents.

       Section 5.8. Separate Tax Lot.  The Land is and will remain assessed for
      ------------  ----------------                                           
real estate tax purposes as one or more wholly independent tax lots, separate
from any property that is not part of the Property.

       Section 5.9. Changes in Zoning or Restrictive Covenants.   Borrower will
      ------------  ------------------------------------------                 
not without Lender's consent (i) initiate, join in or consent to any material
change in any Laws pertaining to zoning, any restrictive covenant or other
restriction which would restrict the permitted uses for the Land and
Improvements, (ii) permit the Land or Improvements to be used to fulfil any
requirements of Law for the construction or maintenance of improvements on
property that is not part of the Property, except to the extent required by any
Permitted Exception; (iii) permit the Land or Improvements to be used for any
purpose not included in the Permitted Use; or (iv) impair the integrity of the
Land as a single, legally subdivided zoning lot separate from all other
property.

       Section 5.10.  Lender's Right to Appear.  After the occurrence of an
      -------------   ------------------------                             
Event of Default, Lender has the right to appear in and defend any Proceeding
brought regarding the Property and to bring any Proceeding, in the name and on
behalf of Borrower or in Lender's name, which Lender, in its sole discretion,
determines should be brought to protect Lender's interest in the Property.


                                   ARTICLE VI

                         IMPOSITIONS AND ACCUMULATIONS
                         -----------------------------

       Section 6.1.  Impositions.
      ------------   ----------- 

     (a) Borrower will pay (or cause to be paid) each Imposition at least 15
days before the date, or such later date permitted under any Lease providing for
direct payment of Impositions by a Tenant, that is the earlier of (i) the date
on which the Imposition becomes 

                                       9
<PAGE>
 
delinquent and (ii) the date on which any penalty, interest or charge for non-
payment of the Imposition accrues (such earlier date being referred to as the
"Imposition Penalty Date") .
 -----------------------    

     (b) Within 30 days after the date of payment required by the preceding
clause (i), Borrower will deliver to Lender a receipted bill or other evidence
of payment.

     (c) Borrower, at its own expense, may contest any Imposition, provided that
                                                                   --------     
the following conditions are met:

     (i) prior to the date on which payment is required to be made pursuant to
     the foregoing clause (a), Borrower delivers to Lender notice of the
     proposed contest;

     (ii) the contest is by a Proceeding promptly initiated and conducted
     diligently and in good faith;

     (iii)  there is no Event of Default;

     (iv) the Proceeding suspends the collection of the contested Imposition or
     Borrower pays such Impositions prior to their delinquency;

     (v) the Proceeding is permitted under and is conducted in accordance with
     the Leases and the Property Documents;

     (vi) the Proceeding precludes imposition of criminal or civil penalties and
     sale or forfeiture of the Property and Lender will not be subject to any
     civil suit;

     (vii)  Borrower pays such Impositions prior to the date of delinquency or
     deposits with the Accumulations Depositary reserves or furnishes a bond or
     other security satisfactory to Lender, in either case in an amount
     sufficient to pay the contested Impositions, together with all interest and
     penalties or Borrower pays all of the contested Impositions under protest.

     (d) Installment Payments.  During the continuance of an Event of Default,
         --------------------                                                 
if any Imposition is payable in installments, Borrower will nevertheless pay the
Imposition in its entirety on the day the first installment becomes due and
payable or a lien, unless Lender, in its sole discretion, approves payment of
the Imposition in installments.

       Section 6.2.  Accumulations.
      ------------   ------------- 

     (a) Borrower made an initial deposit with either Lender or a mortgage
servicer or financial institution designated or approved by Lender from time to
time to receive, hold and disburse the Accumulations in accordance with this
Section (the "Accumulations Depositary"). On the first day of each calendar
              ------------------------                                     
month during the Term Borrower will deposit with the Accumulations Depositary an
amount equal to one-twelfth (1/12) of the annual Impositions and 

                                       10
<PAGE>
 
Insurance Premiums as determined pursuant to Section 3 of the Real Estate Tax
Escrow and Security Agreement executed by Borrower, Lender and Tax Servicer (the
"Tax Agreement"). At least 45 days before each Imposition Penalty Date, Borrower
- --------------
will deliver to the Accumulations Depositary any bills and other documents that
are necessary to pay the Impositions and Insurance Premiums. Borrower shall pay
any fees charged by the Accumulations Depositary in connection with collection
and disbursement of Impositions and Insurance Premiums.

     Notwithstanding the foregoing, so long as Borrower is the owner of the
Property and each of the properties identified in the Commitment (subject to
Substitution in accordance with provisions set forth in Section 12.4 hereof and
Permitted Transfers) and so long as no Event of Default exists Borrower shall
not be required to make such monthly deposits of Insurance Premiums.
Furthermore, subject to the foregoing conditions, Borrower shall not be required
to make such deposits of funds for Impositions with respect to those portions of
the Property that are subject to Leases ("Direct Tax Payment Leases") with third
                                          -------------------------             
parties that are not Affiliates, to the extent that such Leases:

     (i) require such third party tenants to make payments of Impositions
     directly to the relevant taxing authorities; and

     (ii) have been approved by Lender in writing (or are not required to be
     approved by Lender) pursuant to the requirements of the Assignment.

     To the extent that Direct Tax Payment Leases demise less than all the space
in the Property, Borrower shall be required to make deposits with the
Accumulations Depositary for any balance of Impositions that Lender reasonably
determines would be owing with respect to that portion of the Property not
subject to Direct Tax Payment Leases.  In the event that (a) the Accumulations
Depositary notifies the Borrower and the Lender that, on two (2) separate
occasions, a tenant under a Direct Tax Payment Lease has failed to make any
payment of Impositions prior to the time that such payments become delinquent,
or (b) if any such tenant is in monetary default under its Lease, or (c) if such
Lease terminates, then Borrower shall promptly deposit with the Accumulations
Depositary an initial deposit and Borrower shall thereafter make monthly
deposits of funds in respect of such charges as required by Section 6.2(a)
above.

     (b) The Accumulations and deposits on account of Insurance Premiums (to the
extent required to be deposited) will be applied to the payment of Impositions
and Insurance Premiums. Except during the continuance of an Event of Default,
any excess Accumulations or accrued deposits on account of Insurance Premiums
after payment of Impositions and Insurance Premiums will be returned to Borrower
or credited against future payments of the Accumulations and Insurance Premiums,
at Lender's election or as required by Law.  If the Accumulations and accrued
deposits on account of Insurance Premiums are not sufficient to pay Impositions
and Insurance Premiums, Borrower will pay the deficiency to the Accumulations
Depositary within 5 days of demand.  At any time after an Event of Default
occurs, Lender may apply the 

                                       11
<PAGE>
 
Accumulations and accrued deposits on account of Insurance Premiums as a credit
against any portion of the Debt selected by Lender in its sole discretion.

     (c) The Accumulations Depositary will hold the Accumulations and accrued
deposits on account of Insurance Premiums as additional security for the
Obligations until applied in accordance with the provisions of this Mortgage.
If Lender is not the Accumulations Depositary, the Accumulations Depositary will
deliver the Accumulations and accrued deposits on account of Insurance Premiums
to Lender upon Lender's demand at any time after an Event of Default.

     (d) If the Property is sold or conveyed other than by foreclosure or
transfer in lieu of foreclosure and the Loan has not been paid in full, all
right, title and interest of Borrower to the Accumulations and accrued deposits
on account of Insurance Premiums will automatically, and without necessity of
further assignment, be held for the account of the new owner, subject to the
provisions of this Section and Borrower will have no further interest in the
Accumulations and accrued deposits on account of Insurance Premiums.

     (e) The Accumulations Depositary has deposited the initial deposit and will
deposit the monthly deposits into a separate interest bearing account in the
name of Lender as secured party, all in accordance with the Tax Agreement.
Interest shall accrue and be credited upon such deposits in accordance with the
provisions of the Tax Agreement.

     (f) Lender has the right to pay, or to direct the  Accumulations Depositary
to pay, any Impositions or Insurance Premiums unless Borrower is contesting the
Impositions or Assessments in accordance with the provisions of this Mortgage,
in which event any payment of the contested Impositions will be made under
protest in the manner prescribed by Law or, at Lender's election, will be
withheld.

     (g) If Lender assigns this Mortgage, Lender will pay, or cause the
Accumulations Depositary to pay, the unapplied balance of the Accumulations and
accrued deposits on account of Insurance Premiums to or at the direction of the
assignee.  Simultaneously with the payment, Lender and the Accumulations
Depositary will be released from all liability with respect to the Accumulations
and accrued deposits on account of Insurance Premiums and Borrower will look
solely to the assignee with respect to the Accumulations and accrued deposits on
account of Insurance Premiums.  When the Obligations have been fully satisfied,
any unapplied balance of the Accumulations and accrued deposits on account of
Insurance Premiums will be returned to Borrower.

         Section 6.3.  Changes in Tax Laws.  If a Law requires the deduction of
        ------------   -------------------                                     
the Debt from the value of the Property for the purpose of taxation or imposes a
tax, either directly or indirectly, on the Debt, any Loan Document or Lender's
interest in the Property, except a tax on Lender's income, Borrower will pay the
tax with interest and penalties, if any.  If Lender determines that Borrower's
payment of the tax may be unlawful, unenforceable, usurious or taxable to
Lender, the Debt will become immediately due and payable (at par, without

                                       12
<PAGE>
 
prepayment penalty) on 60 days' prior notice unless the tax must be paid within
the 60-day period, in which case, the Debt will be due and payable within the
lesser period.

     Section 6.4.   Payment of Other Property Charges.  (a)  Borrower will pay
     -----------    ---------------------------------                         
(or cause to be paid) each Other Property Charges before the date, or such later
date permitted under any Lease providing for direct payment of Other Property
Charges by a Tenant, that is the earlier of (i) the date on which the Other
Property Charge becomes delinquent and (ii) the date on which any penalty,
interest or charge for non-payment of the Other Property Charge accrues.

     (b) Borrower, at its own expense, may contest any Other Property Charge
provided that such contest is conducted in accordance with the provisions of
Section 12.3 hereof.

       Section 7.1.  Insurance Coverages.
      ------------   ------------------- 

     (a) Borrower will maintain such insurance coverages and endorsements with
respect to the Land, Improvements, Fixtures and Personal Property, in form and
substance and in amounts as Borrower may reasonably determine from time to time,
subject to Lender's reasonable approval. Borrower will maintain not less than
the insurance coverages and endorsements in effect as of the date hereof.

     (b) The insurance, including renewals, required under this Section will be
issued on valid and enforceable policies and endorsements satisfactory to Lender
(in each case to the extent relating to the Land, Improvements and Fixtures, the
"Policies").  Each Policy will contain a standard waiver of subrogation and a
 --------                                                                    
replacement cost endorsement and will provide for Lender to receive not less
than 30 days' prior written notice of any cancellation, termination or non-
renewal of a Policy or any material change other than an increase in coverage
and that Lender will be named under a standard mortgage endorsement as loss
payee.

     (c) The insurance companies issuing the Policies (the "Insurers") must be
                                                            --------

located, must have been in business for at least 5 years, must carry an A.M.
Best Company, Inc. policy holder rating of A or better and an A.M. Best Company,
Inc. financial category rating of Class X or better and must be otherwise
satisfactory to Lender.  Lender may select an alternative credit rating agency
and may impose different credit rating standards for the Insurers.
Notwithstanding Lender's right to approve the Insurers and to establish credit
rating standards for the Insurers, Lender will not be responsible for the
solvency of any Insurer.

                                       13
<PAGE>
 
     (d) Notwithstanding Lender's rights under this Article, Lender will not be
liable for any loss, damage or injury resulting from the inadequacy or lack of
any insurance coverage.

     (e) Borrower will comply with the provisions of the Policies and with the
requirements, notices and demands imposed by the Insurers and applicable to
Borrower or the Property.

     (f) Borrower will pay the Insurance Premiums for each Policy within 30 days
of invoice therefor and in any case in such a timely manner as to prevent lapse
of the Policy being replaced or renewed (except to the extent that Borrower is
required to deposit funds for Insurance Premiums with the Accumulation
Depository, in which case such payments shall be made in accordance with the
provisions of Article VI hereof) and will deliver to Lender an original or, if a
              ----------                                                        
blanket policy, a certified copy of each Policy marked "Paid" not less than 30
days after payment of the Policy being replaced or renewed or other evidence of
payment of such Insurance Premiums reasonably satisfactory to Lender.

     (g) Borrower will not carry separate insurance concurrent in kind or form
or contributing in the event of loss with any other insurance carried by
Borrower.

     (h) Borrower may carry any of the insurance required under this Section on
a blanket or umbrella policy provided that Borrower provides Lender with an
original or copy certified by the insurer of each such policy.  Each such
blanket policy shall allocate to the Property the amount of coverage required
under this Section and otherwise shall provide the same coverage and protection
as would a separate policy insuring only the Property without the possibility of
any reduction of insurance benefits by reason of any claim made against such
policy related to another property insured thereunder.

     (i) Borrower will give the Insurers prompt notice of any change in
ownership or occupancy of the Property.  This subsection does not abrogate the
prohibitions on transfers set forth in this Mortgage.

       Section 7.2.  Casualty and Condemnation.
      ------------   ------------------------- 

     (a) Borrower will give Lender notice of any Casualty immediately after it
occurs and will give Lender notice of any Proceeding in Condemnation immediately
after Borrower receives notice of commencement or notice that such a Proceeding
will be commencing.  Borrower immediately will deliver to Lender copies of all
documents Borrower delivers or receives relating to the Casualty or the
Proceeding, as the case may be.

     (b) Subject to Subsection (c) below, Borrower authorizes Lender, at
Lender's option, to act on Borrower's behalf to collect, adjust and compromise
any claims for loss, damage or destruction under the Policies on such terms as
Lender determines in Lender's sole discretion. Subject to Subsection (c) below,
Borrower authorizes Lender to act, at Lender's option, on Borrower's behalf in
connection with any Condemnation Proceeding.  Borrower will execute and 

                                       14
<PAGE>
 
deliver to Lender all documents requested by Lender and all documents as may be
required by Law to confirm such authorizations. Nothing in this Section will be
construed to limit or prevent Lender from joining with Borrower either as a co-
defendant or as a co-plaintiff if any Condemnation Proceeding.

     (c) If Lender does not to act on Borrower's behalf as provided in this
Section, Borrower promptly will file and prosecute all claims (including
Lender's claims) relating to the Casualty and will prosecute or defend
(including defense of Lender's interest) any Condemnation Proceeding.
Notwithstanding the foregoing Subsection (b), except during the continuance of
an Event of Default, Borrower will have the authority to collect, adjust, settle
or compromise the claims or Proceeding, as the case may be, provided that Lender
                                                            --------

Awards, as the case may be (the "Proceeds") will be made payable to Lender and
                                 --------                                     
Borrower.  Borrower will endorse the check to Lender immediately upon Lender
presenting the check to Borrower for endorsement or if Borrower receives the
check first, will endorse the check immediately upon receipt and forward it to
Lender, to the extent that the Proceeds exceed $1,000,000.00.  If any Proceeds
are paid to Borrower, and such Proceeds exceed $1,000,000.00, Borrower
immediately will deposit the Proceeds with Lender, to be applied or disbursed in
accordance with the provisions of this Mortgage.  Lender will be responsible for
only the Proceeds actually received by Lender.  If the Proceeds are $1,000,000
or less and Borrower is otherwise entitled to hold and apply such Proceeds,
Lender will endorse the check immediately upon receipt and forward it to
Borrower.

       Section 7.3.  Application of Proceeds.  Subject to the provisions of
      ------------   -----------------------                               
Section 7.4 below, after deducting the costs incurred by Lender in collecting
the Proceeds, Lender may, in its sole discretion, (i) apply the Proceeds as a
credit against any portion of the Debt selected by Lender in its sole
discretion; (ii) apply the Proceeds to restore the Improvements, provided that
                                                                 --------     
Lender will not be obligated to see to the proper application of the Proceeds
and provided further that any amounts released for Restoration will not be

     (iv) Borrower pays all costs of Restoration whether or not the Restoration
     Funds are sufficient and, if at any time during Restoration, Lender

while work is in progress, to retain, at Borrower's expense, an independent
engineer or other consultant to review any plans and specifications required by
Lender, to inspect the work as it progresses and to provide reports.  If any
matter included in a report by the engineer or consultant is unsatisfactory to

     (h) If any excess Proceeds remain after Restoration, Lender may elect, in
its sole discretion either to apply the excess as a credit against any portion
of the Debt, at par without penalty or premium, as selected by Lender in its
sole discretion or to deliver the excess to Borrower, provided, however, that if
                                                      --------  -------

     (a) Except as disclosed in the Environmental Report during the period
Borrower or any affiliate of Borrower has owned the Property and as of the date
of this Mortgage:

     (i) to Borrower's knowledge, no Environmental Activity has occurred or is
     occurring on the Property other than the use, storage, and disposal of
     Hazardous Materials in the ordinary course of business consistent with the
     Permitted Use and in compliance with all Environmental Laws without release
     of Hazardous Materials; and

     (ii) to Borrower's knowledge, no Environmental Activity has occurred or is
     occurring on any property in the vicinity of the Property from which there
     is a material risk that Hazardous Materials will migrate, leach, flow,
     drain, seep, blow or drift onto the Property.

     (b) Except as disclosed in the Environmental Report and to Borrower's
knowledge, at all times prior to acquisition of the Property by Borrower or any
affiliate of Borrower:

     (i) no Environmental Activity occurred on the Property other than the use,
     storage and disposal of Hazardous Materials in the ordinary course of
     business consistent with the Permitted Use and in compliance with all
     Environmental Laws without release of Hazardous Materials; and

     (ii) no Environmental Activity occurred on any property in the vicinity of
     the Property from which there is a material risk that Hazardous Materials
     will migrate, leach, flow, drain, seep, blow or drift onto the Property.

     (c) For the purposes of this Section, the phrase "use of the Property"
includes use by tenants and the phrase "on the Property" means on, in, above and

     Section 9.2.  Environmental Covenants.
     -----------   ----------------------- 

     (a) Without limiting the obligation of Borrower to enforce any other
provisions of the Leases, Borrower will enforce all provisions of the Leases
with respect to Environmental Activity.  Without limiting the foregoing,
Borrower shall promptly inspect any portion of the Property as to which Borrower
has information or suspicion that Environmental Activity in violation of a Lease
has occurred or is threatened, and Borrower will promptly require the tenant
under any such Lease to completely remediate the effect of any such
Environmental Activity. Borrower covenants to promptly undertake such
remediation if the tenant under such Lease fails to do so.

                                       20

     (b) Borrower will notify Lender immediately upon Borrower becoming aware of
(i) any actual, suspected or threatened violation of Environmental Laws with
respect to the Property or with respect to any property in the vicinity of the
Property, and (ii) any Environmental Activity with respect to the Property or
with respect to any property in the vicinity of the Property other than the use,
storage, and disposal of Hazardous Materials in the ordinary course of business
consistent with the Permitted Use and in compliance with all Environmental Laws
without release of Hazardous Materials. Borrower promptly will deliver to Lender
copies of all documents delivered to or received by Borrower regarding the
matters set forth in this subsection, including notices of Proceedings or
investigations concerning any Environmental Activity or concerning Borrower's
status as a potentially responsible party (as defined in the Environmental
Laws).  Borrower's notification to Lender in accordance with the provisions of
this subsection will not be deemed to excuse any default under the Loan
Documents resulting from the Environmental Activity or the violation of
Environmental Laws that is the subject of the notice.

     (c) From time to time at Lender's request, Borrower will deliver to Lender
any information known and documents available to Borrower relating to the
environmental condition of the Property.

     (d) Lender may perform or engage an independent consultant to perform an
assessment of the environmental condition of the Property and of Borrower's
compliance with this Section on an annual basis or at any time for reasonable
cause or after an Event of Default. In connection with the assessment:  (i)
subject to the rights of Tenants under Leases and in compliance with Laws,
Lender or consultant may enter and inspect the Property and perform tests of the
air, soil, ground water and building materials; (ii) Borrower will cooperate and
use best efforts to cause tenants and other occupants of the Property to
cooperate with Lender or consultant; (iii) Borrower will accept custody of and
arrange for lawful disposal of any Hazardous Materials required to be disposed
of as a result of the tests; and (iv) neither Lender nor consultant will have
liability to Borrower with respect to the results of the assessment, provided
that Lender or consultant will be responsible for any damage to the Property
resulting from the gross negligence or willful misconduct of Lender's
consultants in performing the tests described in this subsection.  The
consultant's assessment and reports will be at Borrower's expense if the reports
disclose any material adverse change in the environmental condition of the
Property from that disclosed in the Environmental Report or if Lender engaged
the consultant when Lender had reasonable cause to believe Borrower was not in
compliance with the terms of this Article after the occurrence of an Event of
Default.

     (e) If Lender has reasonable cause to believe that there is Environmental
Activity at the Property, Lender may elect in its sole discretion to release
from the lien of this Mortgage any portion of the Property affected by the
Environmental Activity and Borrower will accept the release.

occurrence of an Event of Default case strategy will be determined by Borrower
in reasonable consultation with Lender, and after the occurrence of an Event of
Default, case strategy will be determined by Lender if Lender so elects.  In all
events, no claims against the Lender in the Proceeding will be settled without
Lender's prior approval which may be withheld in its sole discretion.

involuntary, direct or indirect, by operation of law or otherwise and including
the grant of an option or the execution of an agreement relating to any of the

     (i) at least 60 days prior to the proposed Permitted Transfer (except for
     any Permitted Transfer arising from the death of a natural person, in which
     case, not more than 30 days after the death) Borrower delivers to Lender a
     notice that is sufficiently detailed to enable Lender to determine that the

     merger of Existing General Partner with one or more other entities (except
     to the extent that Existing General Partner is the surviving entity after
     such a merger) and (c) the proposed Permitted Transfer will not result in a
     violation of any of the covenants contained in the Section entitled, "ERISA

               or such other professional management firm reasonably acceptable
               to Lender; and

          4.   the transferee is not an employee benefit plan subject to Section

real property collateral securing the Loan coupled with the granting of a
Substitute Mortgage on one or more Substitute Properties shall constitute a
single Substitution.  Any such series of transactions that does not occur within
three (3) consecutive Business Days shall constitute multiple Substitutions.
Borrower shall use its best efforts to refrain from scheduling, closing or
requiring underwriting activity to occur with respect to Substitutions during
the months of November or December.  Lender may not be able, and shall have no
obligation to accommodate a Substitution during such months.

     (c) Value of the Substitute Properties.  Any Substitute Property or
         ----------------------------------                             
Properties shall meet the following criteria:

<PAGE>
 
     (i) the Substitution Loan Value of the Substitute Property or Substitute
     Properties shall be at least 90% of the amount of the Allocated Loan Value
     for the Property.  To the extent that the Substitution Loan Value(s) of the
     Substitute Property(ies) is greater than the Allocated Loan Value, Lender
     shall have no obligation to advance any additional funds. To the extent
     that the Substitution Loan Value of the Substitute Property(ies) is less
     than the Allocated Loan Value, Borrower shall make a partial prepayment of
     the Principal of the Note (which partial prepayment shall constitute a
     Permitted Partial Prepayment as defined in the Note) equal to the excess of
     the Unamortized Allocated Loan Value of the Property over the Substitution
     Loan Value.  The Substitution Loan Value shall in no case be more than
     $1,000,000 less than the Allocated Loan Value.  Any such net cash Permitted
     Partial Prepayment in the amount required or permitted to be paid in
     accordance with Subsections (f) or (g) below (as the case may be) shall be
     subject in all respects to provisions regarding prepayment expressed in
     Section 3(b)(ii) applying the formulas set forth in Section 3(b)(iii) of
     the Note, and the allocation of any such prepayment amount shall be as
     expressed in the Note.

     (ii) the annual Substitute Rents (excluding security deposits) under the
     Substitute Leases in effect on the date of the Substitution shall, on a
     pro-forma basis, provide debt service coverage for the annual Debt Service
     Payments, with respect to the Substitution Property(ies), equal to or
     greater than the debt service coverage applicable to the Property at the
     time of the Substitution, all as calculated on a pro forma basis for next
     consecutive three years (or such lesser period of time remaining in the
     term of the Leases; provided, however, that the foregoing limitation as to
                         --------  -------                                     
     term shall not be construed to require Lender to accept as a Substitute
     Property any property, that in Lender's reasonable judgement has inadequate
     leases in effect), on the basis of Substitute Leases in place at the time
     of the proposed Substitution.

     (d) Requirements for Substitute Properties.  All Substitute Properties must
         --------------------------------------                                 
be acceptable to Lender in all respects, as determined by Lender in its
reasonable discretion applying the following criteria:

     (i)    impact on the geographical concentration of the collateral held by
            Lender as security for the Loan;

     (ii)   leasing considerations, including, without limitation, leasing pro
            formas, tenant credit risk, tenant quality and lease expiration
            risk;

     (iii)  the ability of the proposed Substitute Mortgage to be cross-
            defaulted with and to serve as collateral for the other Loan
            Documents; and

     (iv)   conformity with all the requirements set forth in the Commitment.

                                       30

In addition, all Substitutions shall also comply with the requirements set forth
above in Section 12.2 (a), (c)(i), (c)(iii) & (c)(iv) with respect to Permitted
Transfers, including without limitation, the time periods set forth therein.

     (e) Costs and Expenses of Substitutions.  Borrower will pay all of Lender's
         -----------------------------------                                    
reasonable costs and expenses incurred in connection with a proposed
Substitution, regardless of whether any proposed Substitution is accepted by
Lender.  Borrower acknowledges that such costs and expenses include, without
limitation: Lender's administrative costs, reasonable attorneys' fees and costs,
due diligence costs and expenses, appraisal fees, title insurance fees and
surveyors' charges, all with respect to any proposed Substitution, regardless of
whether or not such proposed Substitution is ultimately closed.  If Borrower
fails to pay such costs and expenses within 30 days of receipt of an invoice
therefor, then such failure shall constitute an Event of Default under Section
14.1(a) of this Mortgage.

     (f) Releases in the Event that No Substitution is Effected.  In the event
         ------------------------------------------------------               
that Borrower enters into an agreement to convey the Property to a third party
that is not an Affiliate, and Borrower has diligently attempted to effect a
Substitution but is unable to secure Lender's approval of a Substitute Property,
then provided that the requirements of Section 12.2 (a), (c)(i), (c)(iii) &
(c)(iv) are met, on the closing date of the sale of the Property, provided that
Lender has been given 20 Business Days' written notice, Lender shall release the
Property from the lien of the Mortgage, provided that Borrower shall prepay to
Lender the Unamortized Allocated Loan Value, together with the Release Fee and
the applicable Prepayment Premium under Section 3(b) of  the Note.  The
Unamortized Allocated Loan Value so prepaid shall be allocated to the Note. Such
prepayment of the Unamortized Allocated Loan Value shall constitute a "Permitted
Partial Prepayment" as defined in the Note and shall be subject to all the
terms, limitations and conditions set forth in Section 3(b)(ii) of the Note.
Notwithstanding the foregoing, Lender's obligation to release the Property under
this Section 12.4(f) shall be conditioned upon Borrower's payment of all
Lender's reasonable costs and expenses (as set forth above in subsection (c)) in
connection with the release and in connection with evaluating any proposed
Substitutions.

     (g) Allocation of Net Cash Payments among Notes.  Any Substitution shall
         -------------------------------------------                         
reduce the Principal of the Note secured by the Mortgage encumbering a Property
being released as part of the Substitution by the Unamortized Allocated Loan
Value of such Property.  The Principal of the Note and any Other Note(s) which
is (are) secured by a Substitute Mortgage(s) shall be increased by the
Substitute Loan Value of the Substitute Property, provided that such increases
shall not exceed the Unamortized Allocated Loan Value of all Properties being
released as a part of such Substitution.   If a Substitute Property is situated
in a state not then represented in the Portfolio, Lender may require that
Borrower execute and deliver an additional promissory note (in form identical to
the Note except for Principal amount and date of issuance) in an amount equal to
the lesser of (a) the Substitution Loan Value of such Substitute Property and
(b) the Unamortized Allocated Loan Value of the Property(ies) being released.
Nothing to the contrary withstanding, it is the intention of the Borrower and
the Lender that the Unamortized Loan Value of the Property(ies) being released
in a Substitution shall be exactly equal to (x) the amount of 
                                             -

                                       31
<PAGE>
 
any Permitted Partial Prepayment calculated as set forth in Section 12.4(c) 
above (but not including the associated Prepayment Premium), plus (y) the 
                                                                   -       
increase in the Principal of the Note or any Other Notes secured by Substitute
Mortgages (including any new promissory note required to be delivered).

     (a) Notwithstanding any provision in the Loan Documents to the contrary,
except as set forth in subsections (b) and (c), if Lender seeks to enforce the
collection of the Debt, Lender will foreclose this Mortgage instead of

this Mortgage and sale of the Property than the then outstanding Debt, Lender
will not institute any Proceeding against Borrower or Borrower's general or
limited partners, or any other direct or indirect owner in Borrower, or their
respective directors, officers, members, shareholders, managers, trustees,
beneficiaries or agents if any, for or on account of the deficiency, except as

     (i) all losses suffered and liabilities and expenses incurred by Lender
     arising out of any fraud or intentional misrepresentation by Borrower or
     any of Borrower's partners, members, officers, directors, shareholders or

     (ii)   all Rents derived from the Property after a default involving
     payment of money under the Loan Documents, except to the extent properly
     applied to payment of Debt Service Payments, Impositions, Insurance
     Premiums, and any reasonable and customary expenses incurred by Borrower in
     the operation, maintenance and leasing of the Property or delivered to
     Lender;

     (iii)  losses covered under the Indemnity;

     (iv)   all security deposits collected by Borrower or any of Borrower's
     predecessors and not refunded to Tenants in accordance with their

     Leases or Law or delivered to Lender, and all advance rents collected by
     Borrower or any of Borrower's predecessors and not applied in accordance
     with the Leases or delivered to Lender;

     from the Property by Borrower after a default occurs;

                                 -------------

       Section 18.1.  Applicable Law.  This instrument is to be governed by and
      -------------   --------------                                           
will be construed in accordance with the Laws of the State or commonwealth where
the Property is located.

       Section 18.2.  Usury Limitations.  Borrower and Lender intend to comply
      -------------   -----------------                                       
with all Laws with respect to the charging and receiving of interest.  Any
amounts charged or received by Lender for the use or forbearance of the
Principal to the extent permitted by Law, will be amortized and spread
throughout the Term until payment in full so that the rate or amount of interest
charged or received by Lender on account of the Principal does not exceed the
Maximum Interest Rate.  If any amount charged or received under the Loan
Documents that is deemed to be interest is determined to be in excess of the
amount permitted to be charged or received at the Maximum Interest Rate, the
excess will be deemed to be a prepayment of Principal when paid, without
premium, and any portion of the excess not capable of being so applied will be
refunded to Borrower.  If during the Term the Maximum Interest Rate, if any, is
eliminated, then for the purposes of the Loan, there will be no Maximum Interest
Rate.

       Section 18.3.  Lender's Discretion.  Wherever under the Loan Documents
      -------------   -------------------                                    
any matter is required to be satisfactory to Lender, Lender has the right to
approve or determine any matter or Lender has an election, Lender's approval,
determination or election will be made in Lender's reasonable discretion unless
expressly provided to the contrary.

       Section 18.4.  Unenforceable Provisions.  If any provision in the Loan
      -------------   ------------------------                               
Documents is found to be illegal or unenforceable or would operate to invalidate
any of the Loan Documents, then the provision will be deemed expunged and the
Loan Documents will be construed as though the provision was not contained in
the Loan Documents and the remainder of the Loan Documents will remain in full
force and effect.

       Section 18.5. Survival of Borrower's Obligations. Borrower's
       ------------- ----------------------------------
      representations, warranties, covenants and indemnities contained in the
      Loan Documents will continue in full force and effect for the period (if
      any) that is expressly provided therefor and shall survive (i) (to the
      extent expressly provided for any such matter) satisfaction of the
      Obligations; (ii) (to the extent expressly provided for any such matter)
      release of the lien of this Mortgage; (iii) assignment or other transfer
      of all or any portion of Lender's interest in the Loan Documents or the
      Property; (iv) (to the extent expressly provided for any such matter)
      Lender's exercise of any of the Remedies or any of Lender's other rights
      under the Loan Documents; (v) except as provided in Section
                                                          -------
      12.2(b)(iii)(2), a Transfer; (vi) amendments to the Loan Documents; and
      --------------
      (vii) any other act or omission not constituting an express release of
      Borrower that might otherwise be construed as a release or discharge of
      Borrower. Nothing contained in this section shall limit the rights of the
      Lender under Section 15.1(c) of this Mortgage.

       Section 18.6.  Relationship Between Borrower and Lender; No Third Party
      -------------   --------------------------------------------------------
Beneficiaries.
- ------------- 

     (a) Lender is not a partner of or joint venturer with Borrower or any other
entity as a result of the Loan or Lender's rights under the Loan Documents; the
relationship between Lender and Borrower is strictly that of creditor and
debtor.  Each Loan Document is an agreement between the parties to that Loan
Document for the mutual benefit of the parties and no entities other than the
parties to that Loan Document will be a third party beneficiary or will have any
claim against Lender or Borrower by virtue of the Loan Document.  As between
Lender and Borrower, any actions taken by Lender under the Loan Documents will
be taken for Lender's protection only, and Lender has not and will not be deemed
to have assumed any responsibility to Borrower or to any other entity by virtue
of Lender's actions.

     (b) All conditions to Lender's performance of its obligations under the
Loan Documents are imposed solely for the benefit of Lender.  No entity other
than Lender will have standing to require satisfaction of the conditions in
accordance with their provisions or will be entitled to assume that Lender will
refuse to perform its obligations in the absence of strict compliance with any
of the conditions.

       Section 18.7.  Partial Releases; Extensions; Waivers.  Lender may: (i)
      -------------   -------------------------------------                  
release any part of the Property or any entity obligated for any of the
Obligations; (ii) extend the time for payment or performance of any of the
Obligations or otherwise amend the provisions for payment or performance by
agreement with any entity that is obligated for the Obligations or that has an
interest in the Property; (iii) accept additional security for the payment and
performance of the Obligations; and (iv) waive any entity's performance of an
Obligation, release any entity or individual now or in the future liable for the
performance of the Obligation or waive the exercise of any Remedy or option.
Lender may exercise any of the foregoing rights without notice, without regard
to the amount of any consideration given, without effecting the priority of the
Loan Documents, without releasing any entity not specifically released from its
obligations under the Loan Documents, without releasing any guarantor(s) or
surety(ies) of any of the Obligations, without effecting a novation of the Loan
Documents and, with respect to a waiver, without waiving future performance of
the Obligation or exercise of the Remedy waived.

       Section 18.8.  Service of Process.  Borrower irrevocably consents to

repayment of a debt, including promises to extend or renew the debt, are not
enforceable.  Any agreements between Borrower and Lender relating to the Loan
are contained in the Loan Documents, which contain the complete and exclusive
statement of the agreements between Borrower and Lender, except as Borrower and
Lender may later agree in writing to amend the Loan Documents.  The language of
each Loan Document will be construed as a whole according to its fair meaning
and will not be construed against the draftsman.

       Section 18.10.  No Oral Amendment.  The Loan Documents may not be
      --------------   -----------------                                
amended, waived or terminated orally or by any act or omission made individually
by Borrower or Lender but may be amended, waived or terminated only by a written
document signed by the party against which enforcement of the amendment, waiver
or termination is sought.

       Section 18.11.  Severability.  The invalidity, illegality or
      --------------   ------------                                
unenforceability of any provision of any of the Loan Documents will not affect
any other provisions of the Loan Documents, which will be construed as if the
invalid, illegal or unenforceable provision never had been included.

       Section 18.12.  Covenants Run with the Land.  Subject to the restrictions
      --------------   ---------------------------

to Borrower's payment and performance of the Obligations.

       Section 18.14.  Subrogation.  If the Principal or any other amount
      --------------   -----------                                       
advanced by Lender is used directly or indirectly to pay off, discharge or
satisfy all or any part of an encumbrance affecting the Property, then Lender is
subrogated to the encumbrance and to any security held by the holder of the
encumbrance, all of which will continue in full force and effect in favor of
Lender as additional security for the Obligations.

       Section 18.15.  [intentionally omitted].

     extent of Lender's damages caused by a prepayment after an Event of Default
     or any other prepayment not permitted by the Loan Documents; and

     (iv) the Prepayment Premium and Evasion Premium represent Lender and
     Borrower's reasonable estimate of Lender's damages for the prepayment and
     is not a penalty.

     of 5 days; or

     associated with recovering the delinquent payment;

     extent of Lender's damages caused by the delinquency; and

                   -----------------------                                  
reference.

RELEASE OF ANY SECURITY FOR THIS NOTE AND AGREE THAT ADDITIONAL MAKERS MAY
BECOME PARTIES TO THIS NOTE AND ADDITIONAL INDORSERS, GUARANTORS OR SURETIES MAY

Lender for the use or forbearance of the Principal to the extent permitted by
Law, will be amortized and spread throughout the Term until payment in full so
that the rate or amount of interest charged or received by Lender on account the
Principal does not exceed the Maximum Interest Rate. If any amount charged or
received under the Loan Documents that is deemed to be interest is determined to
be in excess of the amount permitted to be charged or received at the Maximum
Interest Rate, the excess will be deemed to be a prepayment of Principal when
paid, without premium, and any portion of the excess not capable of being so
applied will be refunded to Borrower. If during the Term the Maximum Interest
Rate, if any, is eliminated, then for purposes of the Loan, there will be no
Maximum Interest Rate.

Notes or an Event of Default (as defined in the respective document) under any
Loan Document constitutes an Event of Default under this Note and under all
other Loan Documents.

     Section 14.  Construction.  Unless expressly provided otherwise in this
     ----------   ------------

     ----------   -------------------                                      
entitled "Limitation of Liability", no reference in this Note to the other Loan
Documents and no other provision of this Note or of the other Loan Documents

Ferdinand Colloredo-Mansfeld:
46 Winthrop Street
South Hamilton, MA 01982


Dear Mr. Colloredo-Mansfeld:

     This letter reflects our agreement relative to your appointment as Chairman
of Cabot Industrial Trust (the "Trust") and your employment by Cabot Industrial
Properties, L.P. (the "Partnership").

     The Partnership agrees to employ you in such capacity for a three-year term
(the "Term"), beginning February 4, 1998 (the "Effective Date").  After the
first anniversary of the Effective Date and on each successive anniversary
thereof, the Term shall be automatically extended for an additional twelve-month
period, unless you or the Partnership provides written notice of non-renewal to
the other at least 120 days before any such anniversary.  During the Term, while
you are employed by the Partnership, you agree that you shall devote
substantially all of your business time, energies and talents to serving as
Chairman of the Trust, you shall perform your duties faithfully and efficiently
subject to the directions of the Board of Trustees of the Trust and you will not
engage, directly or indirectly, in any activities that compete with those of the
Trust or the Partnership.

     During the Term while you are employed by the Partnership, you will be paid
base compensation in the amount of $265,000 per year and you will be eligible
for a cash bonus in such amount as may be determined by the Board of Trustees of
the Trust or the Compensation Committee thereof, in its sole discretion.  The
amount of your base compensation and your bonus will be reviewed by the Board
each year during the Term.  You also will be granted such options under the
Cabot Industrial Trust Long Term Incentive Plan (the "Plan") as the committee of
the Plan determines.

     If, during the Term, after a Change in Control (as described in the Plan),
(i) the Trust or the Partnership or the successor of either  (A) terminates your
employment without Cause (as defined below) or does not extend the Term or (B)
constructively terminates your employment by substantially adversely altering
either your status or responsibilities or your annual base compensation and
bonus from those in effect immediately prior to the Change in Control or by
moving the location of your office more than 50 miles from its then current
location, or (ii) if you terminate your employment on or before the first
anniversary of the Change in Control, you
<PAGE>
 
will be entitled to a lump sum payment as soon as practicable after the date of
such termination, subject to payroll tax withholding as required by law, in an
amount equal to three times the sum of the rate of your annual base compensation
as in effect on such date (or as in effect on the date of the Change in Control,
if higher) plus the amount of your bonus for the year prior to the year in which
your employment terminates; provided, that if termination occurs prior to the
time that a bonus has first been awarded to you hereunder the amount of the
bonus shall be deemed to be the amount of your target incentive bonus as
established by the Board of Trustees or the Compensation Committee thereof or,
if such target bonus has not then been established, 30% of the rate of your
annual base compensation as in effect on such date. In the event it is
determined that any payment or benefit (or combination thereof), including
acceleration of any share options, by the Trust to you or for your benefit would
be subject to the excise tax imposed by section 4999 of the Internal Revenue
Code, the Trust or the Partnership shall pay you a tax gross-up payment in
accordance with Exhibit A, which is attached to and forms a part of this
agreement. For purposes of this agreement, "Cause" shall mean your willful
engaging in conduct which is demonstrably monetarily injurious to the Trust or
the Partnership or your engaging in egregious misconduct involving serious moral
turpitude.

     This letter amends and restates in full our prior Agreement, dated February
4, 1998.  If this letter satisfactorily reflects our agreement, as amended,
please sign and return the attached copy to my attention.  Thank you for your
efforts on behalf of the Trust and the Partnership.

                                    /s/ Robert E. Patterson
                                    _________________________
                                      Robert E. Patterson,
                                      President

Accepted as of this 4th day of
February, 1998.
/s/ Ferdinand Colloredo-Mansfeld

                                   Exhibit A
                                   ---------

                              Tax Gross-Up Payment
                              --------------------

1.   Gross-Up Payment.  In the event that it is determined that any payments,
     ----------------                                                        
     benefits or distributions (or any combination thereof) to or for the
     benefit of Executive (whether paid or payable or distributed or
     distributable pursuant to the terms of the attached letter agreement, or
     otherwise) by the Trust or any of its affiliates (including the
     Partnership) or by one or more trusts established by the Trust or any of
     its affiliates for the benefit of their employees, are subject to the
     excise tax imposed by section 4999 of the Internal Revenue Code of 1986, as
     amended (the "Code"),  which payments are collectively referred to as
     "Parachute Payments", the Trust or the Partnership shall pay to or for the
     benefit of Executive a payment (a "Gross-Up Payment") equal to the sum of
     the following amounts:

     a.   the amount of the excise tax attributable to the Parachute Payments
          (referred to as the "Excise Tax") and the amount of any additional
          excise tax under section 4999 of the Code imposed with respect to
          additional payments, if any, made pursuant to this paragraph 1;

     b.   any interest or penalties incurred by Executive with respect to the
          Excise Tax and other payments, if any, made pursuant to this paragraph
          1; and

     c.   any taxes, including income taxes, incurred by Executive on the Excise
          Tax and other payments, if any, made pursuant to this paragraph 1.

2.   Determination and Payment of Gross-Up Payment.  Subject to the provisions
     ---------------------------------------------                            
     of paragraph 3 below, all determinations required to be made under this
     Exhibit A, including whether and when a Gross-Up Payment is required and
     the amount of such Gross-Up Payment and the assumptions to be utilized in
     arriving at such determination, shall be made by a nationally recognized
     certified public accounting firm as may be designated by the Trust or the
     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"),
<PAGE>
 
     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a

                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.

Dear Mr. Patterson:

     This letter reflects our agreement relative to your appointment as
President of Cabot Industrial Trust (the "Trust") and your employment by Cabot
Industrial Properties, L.P. (the "Partnership").

     The Partnership agrees to employ you in such capacity for a three-year term
(the "Term"), beginning February 4, 1998 (the "Effective Date").  After the
first anniversary of the Effective Date and on each successive anniversary
thereof, the Term shall be automatically extended for an additional twelve-month
period, unless you or the Partnership provides written notice of non-renewal to
the other at least 120 days before any such anniversary. During the Term, while
you are employed by the Partnership, you agree that you shall devote
substantially all of your business time, energies and talents to serving as
President of the Trust, you shall perform your duties faithfully and efficiently
subject to the directions of the Chairman of the Trust and you will not engage,
directly or indirectly, in any activities that compete with those of the Trust
or the Partnership.

     During the Term while you are employed by the Partnership, you will be paid
base compensation in the amount of $245,000 per year and you will be eligible
for a cash bonus in such amount as may be determined by the Board of Trustees of
the Trust or the Compensation Committee thereof, in its sole discretion.  The
amount of your base compensation and your bonus will be reviewed by the Board
each year during the Term.  You also will be granted such options under the
Cabot Industrial Trust Long Term Incentive Plan (the "Plan") as the committee of
the Plan determines.

     If, during the Term, after a Change in Control (as described in the Plan),
(i) the Trust or the Partnership or the successor of either  (A) terminates your
employment without Cause (as defined below) or does not extend the Term or (B)
constructively terminates your employment by substantially adversely altering
either your status or responsibilities or your annual base compensation and
bonus from those in effect immediately prior to the Change in Control or by
moving the location of your office more than 50 miles from its then current
location, or (ii) if you terminate your employment on or before the first
anniversary of the Change in Control, you will be entitled to a lump sum payment
as soon as practicable after the date of such termination,
<PAGE>
 
subject to payroll tax withholding as required by law, in an amount equal to
three times the sum of the rate of your annual base compensation as in effect on
such date (or as in effect on the date of the Change in Control, if higher) plus
the amount of your bonus for the year prior to the year in which your employment
terminates; provided, that if termination occurs prior to the time that a bonus
has first been awarded to you hereunder the amount of the bonus shall be deemed
to be the amount of your target incentive bonus as established by the Board of
Trustees or the Compensation Committee thereof or, if such target bonus has not
then been established, 30% of the rate of your annual base compensation as in
effect on such date. In the event it is determined that any payment or benefit
(or combination thereof), including acceleration of any share options, by the
Trust to you or for your benefit would be subject to the excise tax imposed by
section 4999 of the Internal Revenue Code, the Trust or the Partnership shall
pay you a tax gross-up payment in accordance with Exhibit A, which is attached
to and forms a part of this agreement. For purposes of this agreement, "Cause"
shall mean your willful engaging in conduct which is demonstrably monetarily
injurious to the Trust or the Partnership or your engaging in egregious
misconduct involving serious moral turpitude.

     This letter amends and restates in full our prior Agreement, dated February
4, 1998.  If this letter satisfactorily reflects our agreement, as amended,
please sign and return the attached copy to my attention.  Thank you for your
efforts on behalf of the Trust and the Partnership.

                              /s/ Ferdinand Colloredo-Mansfeld

Accepted as of this 4th day of
February, 1998.

                                   ---------

                              Tax Gross-Up Payment
                              --------------------

1.   Gross-Up Payment.  In the event that it is determined that any payments,
     ----------------                                                        
     benefits or distributions (or any combination thereof) to or for the
     benefit of Executive (whether paid or payable or distributed or
     distributable pursuant to the terms of the attached letter agreement, or
     otherwise) by the Trust or any of its affiliates (including the
     Partnership) or by one or more trusts established by the Trust or any of
     its affiliates for the benefit of their employees, are subject to the
     excise tax imposed by section 4999 of the Internal Revenue Code of 1986, as
     amended (the "Code"),  which payments are collectively referred to as
     "Parachute Payments", the Trust or the Partnership shall pay to or for the
     benefit of Executive a payment (a "Gross-Up Payment") equal to the sum of
     the following amounts:

     a.   the amount of the excise tax attributable to the Parachute Payments
          (referred to as the "Excise Tax") and the amount of any additional
          excise tax under section 4999 of the Code imposed with respect to
          additional payments, if any, made pursuant to this paragraph 1;

     b.   any interest or penalties incurred by Executive with respect to the
          Excise Tax and other payments, if any, made pursuant to this paragraph
          1; and

     c.   any taxes, including income taxes, incurred by Executive on the Excise
          Tax and other payments, if any, made pursuant to this paragraph 1.

2.   Determination and Payment of Gross-Up Payment.  Subject to the provisions
     ---------------------------------------------                            
     of paragraph 3 below, all determinations required to be made under this
     Exhibit A, including whether and when a Gross-Up Payment is required and
     the amount of such Gross-Up Payment and the assumptions to be utilized in
     arriving at such determination, shall be made by a nationally recognized
     certified public accounting firm as may be designated by the Trust or the
     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"),
<PAGE>
 
     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a

                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.

     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"),
<PAGE>
 
     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a

                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.

Dear Mr. Ebbott:

     This letter reflects our agreement relative to your appointment as Senior
Vice President of Cabot Industrial Trust (the "Trust") and your employment by
Cabot Industrial Properties, L.P. (the "Partnership").

     The Partnership agrees to employ you in such capacity for a two-year term
(the "Term"), beginning February 4, 1998 (the "Effective Date").  After the
first anniversary of the Effective Date and on each successive anniversary
thereof, the Term shall be automatically extended for an additional twelve-month
period, unless you or the Partnership provides written notice of non-renewal to
the other at least 120 days before any such anniversary.  During the Term, while
you are employed by the Partnership, you agree that you shall devote
substantially all of your business time, energies and talents to serving as
Senior Vice President of the Trust, you shall perform your duties faithfully and
efficiently subject to the directions of the Chairman of the Trust and you will
not engage, directly or indirectly, in any activities that compete with those of
the Trust or the Partnership.

     During the Term while you are employed by the Partnership, you will be paid
base compensation in the amount of $175,000 per year and you will be eligible
for a cash bonus in such amount as may be determined by the Board of Trustees of
the Trust or the Compensation Committee thereof, in its sole discretion.  The
amount of your base compensation and your bonus will be reviewed by the Board
each year during the Term.  You also will be granted such options under the
Cabot Industrial Trust Long Term Incentive Plan (the "Plan") as the committee of
the Plan determines.

     If, during the Term, after a Change in Control (as described in the Plan),
(i) the Trust or the Partnership or the successor of either  (A) terminates your
employment without Cause (as defined below) or does not extend the Term or (B)
constructively terminates your employment by substantially adversely altering
either your status or responsibilities or your annual base compensation and
bonus from those in effect immediately prior to the Change in Control or by
moving the location of your office more than 50 miles from its then current
location, or (ii) if you terminate your employment on or before the first
anniversary of the Change in Control, you
<PAGE>
 
will be entitled to a lump sum payment as soon as practicable after the date of
such termination, subject to payroll tax withholding as required by law, in an
amount equal to three times the sum of the rate of your annual base compensation
as in effect on such date (or as in effect on the date of the Change in Control,
if higher) plus the amount of your bonus for the year prior to the year in which
your employment terminates; provided, that if termination occurs prior to the
time that a bonus has first been awarded to you hereunder the amount of the
bonus shall be deemed to be the amount of your target incentive bonus as
established by the Board of Trustees or the Compensation Committee thereof or,
if such target bonus has not then been established, 30% of the rate of your
annual base compensation as in effect on such date. In the event it is
determined that any payment or benefit (or combination thereof), including
acceleration of any share options, by the Trust to you or for your benefit would
be subject to the excise tax imposed by section 4999 of the Internal Revenue
Code, the Trust or the Partnership shall pay you a tax gross-up payment in
accordance with Exhibit A, which is attached to and forms a part of this
agreement. For purposes of this agreement, "Cause" shall mean your willful
engaging in conduct which is demonstrably monetarily injurious to the Trust or
the Partnership or your engaging in egregious misconduct involving serious moral
turpitude.

     This letter amends and restates in full our prior Agreement, dated February
4, 1998.  If this letter satisfactorily reflects our agreement, as amended,
please sign and return the attached copy to my attention.  Thank you for your
efforts on behalf of the Trust and the Partnership.

                                   ---------

                              Tax Gross-Up Payment
                              --------------------

1.   Gross-Up Payment.  In the event that it is determined that any payments,
     ----------------                                                        
     benefits or distributions (or any combination thereof) to or for the
     benefit of Executive (whether paid or payable or distributed or
     distributable pursuant to the terms of the attached letter agreement, or
     otherwise) by the Trust or any of its affiliates (including the
     Partnership) or by one or more trusts established by the Trust or any of
     its affiliates for the benefit of their employees, are subject to the
     excise tax imposed by section 4999 of the Internal Revenue Code of 1986, as
     amended (the "Code"),  which payments are collectively referred to as
     "Parachute Payments", the Trust or the Partnership shall pay to or for the
     benefit of Executive a payment (a "Gross-Up Payment") equal to the sum of
     the following amounts:

     a.   the amount of the excise tax attributable to the Parachute Payments
          (referred to as the "Excise Tax") and the amount of any additional
          excise tax under section 4999 of the Code imposed with respect to
          additional payments, if any, made pursuant to this paragraph 1;

     b.   any interest or penalties incurred by Executive with respect to the
          Excise Tax and other payments, if any, made pursuant to this paragraph
          1; and

     c.   any taxes, including income taxes, incurred by Executive on the Excise
          Tax and other payments, if any, made pursuant to this paragraph 1.

2.   Determination and Payment of Gross-Up Payment.  Subject to the provisions
     ---------------------------------------------                            
     of paragraph 3 below, all determinations required to be made under this
     Exhibit A, including whether and when a Gross-Up Payment is required and
     the amount of such Gross-Up Payment and the assumptions to be utilized in
     arriving at such determination, shall be made by a nationally recognized
     certified public accounting firm as may be designated by the Trust or the
     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"),
<PAGE>
 
     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a

                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.

     its affiliates for the benefit of their employees, are subject to the
     excise tax imposed by section 4999 of the Internal Revenue Code of 1986, as
     amended (the "Code"),  which payments are collectively referred to as
     "Parachute Payments", the Trust or the Partnership shall pay to or for the
     benefit of Executive a payment (a "Gross-Up Payment") equal to the sum of
     the following amounts:

     a.   the amount of the excise tax attributable to the Parachute Payments
          (referred to as the "Excise Tax") and the amount of any additional
          excise tax under section 4999 of the Code imposed with respect to
          additional payments, if any, made pursuant to this paragraph 1;

     b.   any interest or penalties incurred by Executive with respect to the
          Excise Tax and other payments, if any, made pursuant to this paragraph
          1; and

     c.   any taxes, including income taxes, incurred by Executive on the Excise
          Tax and other payments, if any, made pursuant to this paragraph 1.

2.   Determination and Payment of Gross-Up Payment.  Subject to the provisions
     ---------------------------------------------                            
     of paragraph 3 below, all determinations required to be made under this
     Exhibit A, including whether and when a Gross-Up Payment is required and
     the amount of such Gross-Up Payment and the assumptions to be utilized in
     arriving at such determination, shall be made by a nationally recognized
     certified public accounting firm as may be designated by the Trust or the
     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"), 
<PAGE>
 
     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a 

                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.

Dear Mr. Waisnor:

     This letter reflects our agreement relative to your appointment as Senior
Vice President of Cabot Industrial Trust (the "Trust") and your employment by
Cabot Industrial Properties, L.P. (the "Partnership").

     The Partnership agrees to employ you in such capacity for a two-year term
(the "Term"), beginning February 4, 1998 (the "Effective Date").  After the
first anniversary of the Effective Date and on each successive anniversary
thereof, the Term shall be automatically extended for an additional twelve-month
period, unless you or the Partnership provides written notice of non-renewal to
the other at least 120 days before any such anniversary.  During the Term, while
you are employed by the Partnership, you agree that you shall devote
substantially all of your business time, energies and talents to serving as
Senior Vice President of the Trust, you shall perform your duties faithfully and
efficiently subject to the directions of the Chairman of the Trust and you will
not engage, directly or indirectly, in any activities that compete with those of
the Trust or the Partnership.

     During the Term while you are employed by the Partnership, you will be paid
base compensation in the amount of $175,000 per year and you will be eligible
for a cash bonus in such amount as may be determined by the Board of Trustees of
the Trust or the Compensation Committee thereof, in its sole discretion.  The
amount of your base compensation and your bonus will be reviewed by the Board
each year during the Term.  You also will be granted such options under the
Cabot Industrial Trust Long Term Incentive Plan (the "Plan") as the committee of
the Plan determines.

     If, during the Term, after a Change in Control (as described in the Plan),
(i) the Trust or the Partnership or the successor of either  (A) terminates your
employment without Cause (as defined below) or does not extend the Term or (B)
constructively terminates your employment by substantially adversely altering
either your status or responsibilities or your annual base compensation and
bonus from those in effect immediately prior to the Change in Control or by
moving the location of your office more than 50 miles from its then current
location, or (ii) if you terminate your employment on or before the first
anniversary of the Change in Control, you 
<PAGE>
 
will be entitled to a lump sum payment as soon as practicable after the date of
such termination, subject to payroll tax withholding as required by law, in an
amount equal to three times the sum of the rate of your annual base compensation
as in effect on such date (or as in effect on the date of the Change in Control,
if higher) plus the amount of your bonus for the year prior to the year in which
your employment terminates; provided, that if termination occurs prior to the
time that a bonus has first been awarded to you hereunder the amount of the
bonus shall be deemed to be the amount of your target incentive bonus as
established by the Board of Trustees or the Compensation Committee thereof or,
if such target bonus has not then been established, 30% of the rate of your
annual base compensation as in effect on such date. In the event it is
determined that any payment or benefit (or combination thereof), including
acceleration of any share options, by the Trust to you or for your benefit would
be subject to the excise tax imposed by section 4999 of the Internal Revenue
Code, the Trust or the Partnership shall pay you a tax gross-up payment in
accordance with Exhibit A, which is attached to and forms a part of this
agreement. For purposes of this agreement, "Cause" shall mean your willful
engaging in conduct which is demonstrably monetarily injurious to the Trust or
the Partnership or your engaging in egregious misconduct involving serious moral
turpitude.

     This letter amends and restates in full our prior Agreement, dated February
4, 1998.  If this letter satisfactorily reflects our agreement, as amended,
please sign and return the attached copy to my attention.  Thank you for your
efforts on behalf of the Trust and the Partnership.

                                         /s/ Robert E. Patterson,
                                         ________________________

                                             President

Accepted this 4th day of
February, 1998.

                                   ---------

                              Tax Gross-Up Payment
                              --------------------

1.   Gross-Up Payment.  In the event that it is determined that any payments,
     ----------------                                                        
     benefits or distributions (or any combination thereof) to or for the
     benefit of Executive (whether paid or payable or distributed or
     distributable pursuant to the terms of the attached letter agreement, or
     otherwise) by the Trust or any of its affiliates (including the
     Partnership) or by one or more trusts established by the Trust or any of
     its affiliates for the benefit of their employees, are subject to the
     excise tax imposed by section 4999 of the Internal Revenue Code of 1986, as
     amended (the "Code"),  which payments are collectively referred to as
     "Parachute Payments", the Trust or the Partnership shall pay to or for the
     benefit of Executive a payment (a "Gross-Up Payment") equal to the sum of
     the following amounts:

     a.   the amount of the excise tax attributable to the Parachute Payments
          (referred to as the "Excise Tax") and the amount of any additional
          excise tax under section 4999 of the Code imposed with respect to
          additional payments, if any, made pursuant to this paragraph 1;

     b.   any interest or penalties incurred by Executive with respect to the
          Excise Tax and other payments, if any, made pursuant to this paragraph
          1; and

     c.   any taxes, including income taxes, incurred by Executive on the Excise
          Tax and other payments, if any, made pursuant to this paragraph 1.

2.   Determination and Payment of Gross-Up Payment.  Subject to the provisions
     ---------------------------------------------                            
     of paragraph 3 below, all determinations required to be made under this
     Exhibit A, including whether and when a Gross-Up Payment is required and
     the amount of such Gross-Up Payment and the assumptions to be utilized in
     arriving at such determination, shall be made by a nationally recognized
     certified public accounting firm as may be designated by the Trust or the
     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"),

     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a 
                                       
                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.

Dear Mr. Reilly:

     This letter reflects our agreement relative to your appointment as Senior
Vice President of Cabot Industrial Trust (the "Trust") and your employment by
Cabot Industrial Properties, L.P. (the "Partnership").

     The Partnership agrees to employ you in such capacity for a two-year term
(the "Term"), beginning February 4, 1998 (the "Effective Date").  After the
first anniversary of the Effective Date and on each successive anniversary
thereof, the Term shall be automatically extended for an additional twelve-month
period, unless you or the Partnership provides written notice of non-renewal to
the other at least 120 days before any such anniversary.  During the Term, while
you are employed by the Partnership, you agree that you shall devote
substantially all of your business time, energies and talents to serving as
Senior Vice President of the Trust, you shall perform your duties faithfully and
efficiently subject to the directions of the Chairman of the Trust and you will
not engage, directly or indirectly, in any activities that compete with those of
the Trust or the Partnership.

     During the Term while you are employed by the Partnership, you will be paid
base compensation in the amount of $175,000 per year and you will be eligible
for a cash bonus in such amount as may be determined by the Board of Trustees of
the Trust or the Compensation Committee thereof, in its sole discretion.  The
amount of your base compensation and your bonus will be reviewed by the Board
each year during the Term.  You also will be granted such options under the
Cabot Industrial Trust Long Term Incentive Plan (the "Plan") as the committee of
the Plan determines.

     If, during the Term, after a Change in Control (as described in the Plan),
(i) the Trust or the Partnership or the successor of either  (A) terminates your
employment without Cause (as defined below) or does not extend the Term or (B)
constructively terminates your employment by substantially adversely altering
either your status or responsibilities or your annual base compensation and
bonus from those in effect immediately prior to the Change in Control or by
moving the location of your office more than 50 miles from its then current
location, or (ii) if
<PAGE>
 
you terminate your employment on or before the first anniversary of the Change
in Control, you will be entitled to a lump sum payment as soon as practicable
after the date of such termination, subject to payroll tax withholding as
required by law, in an amount equal to three times the sum of the rate of your
annual base compensation as in effect on such date (or as in effect on the date
of the Change in Control, if higher) plus the amount of your bonus for the year
prior to the year in which your employment terminates; provided, that if
termination occurs prior to the time that a bonus has first been awarded to you
hereunder the amount of the bonus shall be deemed to be the amount of your
target incentive bonus as established by the Board of Trustees or the
Compensation Committee thereof or, if such target bonus has not then been
established, 30% of the rate of your annual base compensation as in effect on
such date. In the event it is determined that any payment or benefit (or
combination thereof), including acceleration of any share options, by the Trust
to you or for your benefit would be subject to the excise tax imposed by section
4999 of the Internal Revenue Code, the Trust or the Partnership shall pay you a
tax gross-up payment in accordance with Exhibit A, which is attached to and
forms a part of this agreement. For purposes of this agreement, "Cause" shall
mean your willful engaging in conduct which is demonstrably monetarily injurious
to the Trust or the Partnership or your engaging in egregious misconduct
involving serious moral turpitude.

     This letter amends and restates in full our prior Agreement, dated February

                                   Exhibit A
                                   ---------

                              Tax Gross-Up Payment
                              --------------------

1.   Gross-Up Payment.  In the event that it is determined that any payments,
     ----------------                                                        
     benefits or distributions (or any combination thereof) to or for the
     benefit of Executive (whether paid or payable or distributed or
     distributable pursuant to the terms of the attached letter agreement, or
     otherwise) by the Trust or any of its affiliates (including the
     Partnership) or by one or more trusts established by the Trust or any of
     its affiliates for the benefit of their employees, are subject to the
     excise tax imposed by section 4999 of the Internal Revenue Code of 1986, as
     amended (the "Code"),  which payments are collectively referred to as
     "Parachute Payments", the Trust or the Partnership shall pay to or for the
     benefit of Executive a payment (a "Gross-Up Payment") equal to the sum of
     the following amounts:

     a.   the amount of the excise tax attributable to the Parachute Payments
          (referred to as the "Excise Tax") and the amount of any additional
          excise tax under section 4999 of the Code imposed with respect to
          additional payments, if any, made pursuant to this paragraph 1;

     b.   any interest or penalties incurred by Executive with respect to the
          Excise Tax and other payments, if any, made pursuant to this paragraph
          1; and

     c.   any taxes, including income taxes, incurred by Executive on the Excise
          Tax and other payments, if any, made pursuant to this paragraph 1.

2.   Determination and Payment of Gross-Up Payment.  Subject to the provisions
     ---------------------------------------------                            
     of paragraph 3 below, all determinations required to be made under this
     Exhibit A, including whether and when a Gross-Up Payment is required and
     the amount of such Gross-Up Payment and the assumptions to be utilized in
     arriving at such determination, shall be made by a nationally recognized
     certified public accounting firm as may be designated by the Trust or the
     Partnership (the "Accounting Firm") which shall provide detailed supporting
     calculations to the Trust, the Partnership and Executive within fifteen
     (15) business days of the effective time of a Change in Control or such
     earlier time as is requested by the Trust or the Partnership.  All fees and
     expenses of the Accounting Firm shall be borne solely by the Trust or the
     Partnership.  Any Gross-Up Payment, as determined pursuant to paragraph 1,
     shall be paid by the Trust or the Partnership to Executive within five (5)
     days after the receipt of the Accounting Firm's determination. If the
     Accounting Firm determines that no Excise Tax is payable by Executive, it
     shall so indicate to Executive in writing.  Any determination by the
     Accounting Firm shall be binding upon the Trust, the Partnership and
     Executive.  As a result of the uncertainty in the application of section
     4999 of the Code at the time of the initial determination by the Accounting
     Firm hereunder, it is possible that a Gross-Up Payment which will not have
     been made by the Trust or the Partnership should have been made
     ("Underpayment"),
<PAGE>
 
     consistent with the calculations required to be made hereunder. In the
     event that the Trust or the Partnership exhausts its remedies pursuant to
     paragraph 3 and Executive thereafter is required to make a payment of any
     Excise Tax, the Accounting Firm shall determine the amount of the
     Underpayment that has occurred and any such Underpayment shall be promptly
     paid by the Trust or the Partnership to or for the benefit of Executive.

3.   Claims by IRS.  Executive shall notify the Trust and the Partnership in
     -------------                                                          
     writing of any claim by the Internal Revenue Service that, if successful,
     would require the payment by the Trust or the Partnership of the Gross-Up
     Payment.  Such notification shall be given as soon as practicable but no
     later than ten (10) business days after Executive is informed in writing of
     such claim and shall apprise the Trust and the Partnership of the nature of
     such claim and the date on which such claim is requested to be paid.
     Executive shall not pay such claim prior to the expiration of the thirty
     (30) day period following the date on which it gives such notice to the
     Trust and the Partnership (or such shorter period ending on the date that
     any payment of taxes with respect to such claim is due).  If the Trust or
     the Partnership notifies Executive in writing prior to the expiration of
     such period that it desires to contest such claim, Executive shall:

     a.   give the Trust and the Partnership any information requested by either
          relating to such claim;

     b.   take such action in connection with contesting such claim as the Trust
          or the Partnership shall reasonably request in writing from time to
          time, including, without limitation, accepting legal representation
          with respect to such claim by an attorney reasonably selected by the
          Trust or the Partnership;

     c.   cooperate with the Trust and the Partnership in good faith in order to
          effectively contest such claim; and

     d.   permit the Trust and the Partnership to participate in any proceedings
          relating to such claim;

     provided, however, that the Trust or the Partnership shall bear and pay
     directly all costs and expenses (including additional interest and
     penalties) incurred in connection with such contest and shall indemnify and
     hold Executive harmless, on an after-tax basis, for any Excise Tax or
     income tax (including interest and penalties with respect thereto) imposed
     as a result of such representation and payment of costs and expenses.
     Without limitation on the foregoing provisions of this paragraph 3, the
     Trust or the Partnership shall control all proceedings taken in connection
     with such contest and, at its sole option, may pursue or forego any and all
     administrative appeals, proceedings, hearings and conferences with the
     taxing authority in respect of such claim and may, at its sole option,
     either direct Executive to pay the tax claimed and sue for a refund or
     contest the claim in any permissible manner, and Executive agrees to
     prosecute such contest to a

                                       2
<PAGE>
 
     determination before any administrative tribunal, in a court of initial
     jurisdiction and in one or more appellate courts, as the Trust or the
     Partnership shall determine; provided, however, that if the Trust or the
     Partnership directs Executive to pay such claim and sue for a refund, the
     Trust or the Partnership shall advance the amount of such payment to
     Executive, on an interest-free basis, and shall indemnify and hold
     Executive harmless, on an after-tax basis, from any Excise Tax or income
     tax (including interest or penalties with respect thereto) imposed with
     respect to such advance or with respect to any imputed income with respect
     to such advance; and provided, further, that if Executive is required to
     extend the statute of limitations to enable the Trust or the Partnership to
     contest such claim, Executive may limit this extension solely to such
     contested amount. The control of the contest by the Trust or the
     Partnership shall be limited to issues with respect to which a Gross-Up
     Payment would be payable hereunder and Executive shall be entitled to
     settle or contest, as the case may be, any other issue raised by the
     Internal Revenue Service or any other taxing authority.

4.   Refunds.  If, after the receipt by Executive of an amount advanced by the
     -------                                                                  
     Trust or the Partnership pursuant to paragraph 3, Executive becomes
     entitled to receive any refund with respect to such claim, Executive shall
     (subject to the Trust's or the Partnership's complying with the
     requirements of paragraph 3) promptly pay to the Trust or the Partnership
     the amount of such refund (together with any interest paid or credited
     thereon after taxes applicable thereto).  If, after the receipt by
     Executive of an amount advanced by the Trust or the Partnership pursuant to
     paragraph 3, a determination is made that Executive shall not be entitled
     to any refund with respect to such claim and the Trust or the Partnership
     does not notify Executive in writing of its intent to contest such denial
     of refund prior to the expiration of thirty (30) days after such
     determination, then such advance shall be forgiven and shall not be
     required to be repaid and the amount of such advance shall offset, to the
     extent thereof, the amount of Gross-Up Payment required to be paid.
