                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                              As of March 31, 1999

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 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 Note 2), the results for the three months ended
March 31, 1998, represent activity for 56 days, or approximately 2 months.

As of March 31, 1999, Cabot Trust owned 242 industrial properties located in 21
markets throughout the United States and containing approximately 30 million
rentable square feet. These properties were approximately 97% leased to 473
tenants at March 31, 1999.

2. The Formation Transactions, The Offerings and Ownership

Initial Capitalization

The initial capitalization of Cabot Trust consisted of 50 common shares of
beneficial interest (Common Shares), par value $.01 per share, 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 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 are
exchangeable, subject to certain restrictions, for Common Shares of Cabot Trust
or (ii) contributed to Cabot Trust in exchange for Common Shares. The properties
contributed to Cabot Trust were contributed 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.

During the quarter ended March 31, 1999, Cabot L.P. issued 143,087 Units in
conjunction with an acquisition and Cabot Trust issued 21,931,507 Common Shares
in exchange for Units of Cabot L.P. As a result, Cabot Trust owned 92.9% of
Cabot L.P. as of March 31, 1999. The remaining 7.1%, which is owned by investors
holding Cabot L.P. Units, is considered minority interest.

Shares at an offering price of $20.00 per share. In addition, Cabot Trust issued
1,000,000 Common Shares to a single investor 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.

Distributions

On March 10, 1999, Cabot Trust and Cabot L.P. declared distributions of $.34 per
Share/Unit payable on April 30, 1999 to Shareholders or Unitholders of record as
of April 9, 1999.

4. Debt Activity

In conjunction with certain acquisitions made during the quarter ended March 31,
1999, Cabot Trust assumed debt of $14.5 million with coupon interest rates
ranging from 7.375% to 9.375%, secured by properties with a net book value of
approximately $26 million. In addition, in February 1999, Cabot L.P. borrowed
$87.6 million secured by properties with a net book value of approximately $130
million at March 31, 1999. This 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. An additional $5.6 million was borrowed
under this arrangement in April 1999. This borrowing is subject to various
customary covenants. The proceeds from the borrowing were used to repay a
portion of the balance outstanding under Cabot Trust's Acquisition Facility.

During 1998 Cabot Trust entered into an interest rate hedge transaction
(referred to as a Treasury Lock) 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. At the March 31, 1999 contractual settlement date for this
transaction, Cabot Trust paid $2.5 million to its counter party in the
transaction, reflecting the decrease in Treasury security yields since the July
1998 commencement of the transaction. Because an offering of the size and
maturity contemplated when the interest rate hedge transaction was executed was
not completed by the time of, or shortly after, the March 31, 1999 settlement
date of the transaction, Cabot Trust recorded a loss related to the Settlement
of Treasury Lock of $2.5 million in the quarter ended March 31, 1999.

5. Earnings per Share

In accordance with Statement of Financial Accounting Standards 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

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

The statements contained in this discussion and elsewhere in this report that
are not historical facts are forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. These forward-looking statements are based on current

Therefore, actual outcomes and results may differ materially from what is
expressed or suggested by such forward-looking statements. Cabot Trust
undertakes no obligation to update publicly any forward-looking statements,
whether as a result of new information, future events or otherwise. Cabot
Trust's operating results depend primarily on income from industrial properties,
which may be affected by various factors, including changes in national and
local economic conditions, competitive market conditions, uncertainties and
costs related to and the imposition of conditions on receipt of governmental
approvals and costs of material and labor, all of 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 capital also influence operating
results.

Introduction

Cabot Trust is an internally managed, fully integrated real estate company,
focused on serving a variety of industrial space users in the country's
principal commercial markets. Cabot Trust owns and operates a diversified
portfolio of bulk distribution, multitenant distribution and "workspace" (light
industrial, R&D and similar facilities) properties throughout the United States.
At March 31, 1999, Cabot Trust owned 242 industrial properties, 34 of which
properties were acquired during the period from January 1, 1999, through March
31, 1999. Cabot Trust was formed on October 10, 1997, but did not begin
operations as a fully integrated real estate company until the completion of its
Formation Transactions and Offerings on February 4, 1998, the date of Cabot
Trust's initial public offering. Cabot Trust had no operations prior to February
4, 1998.

Results of Operations

Since Cabot Trust did not begin operations until February 4, 1998, the results
for the three months ended March 31, 1998, represent activity for only 56 days.

Quarter Ended March 31, 1999 Compared with Quarter Ended March 31, 1998

Net income attributable to common shareholders for the quarter ended March 31,
1999, totaled $7.7 million or $.28 per share, compared to $3.5 million or $.19
per share for the quarter ended March 31, 1998. The increase in net income
allocable to common shareholders is due to the conversion of Units to Common
Shares discussed in Note 2 to the financial statements, which resulted in a
decrease in the allocation of income to minority interest, but has no effect on
net income per share. The increase is also the result of the full quarter of
operations in 1999 compared to 56 days in 1998 and increased earnings due
primarily to increased investment in real properties.

Rental revenues were $34.1 million, including tenant reimbursements of $4.9
million, for the quarter ended March 31, 1999, compared to $14.7 million,
including tenant reimbursements of $1.9 million, for the quarter ended March 31,
1998. Total rental revenue of $20.9 million and $12.6 million was 
<PAGE>
 
generated in 1999 and 1998, respectively, by the 121 properties owned as of
February 4, 1998 as a result of the Formation Transactions and still owned at
March 31, 1999, (the Baseline Properties) and total rental revenue of $13.2
million and $2.0 million in 1999 and 1998, respectively, was generated by the
121 properties acquired or developed subsequent to February 4, 1998. The
remainder of total rental revenue for 1998 relates to a property sold in 1998.
Depreciation and amortization related to real estate investments totaled $6.8
million and $3.2 million for the quarters ended March 31, 1999 and 1998,
respectively. The increase reflects the acquisition of real estate assets and 90
days of operations in 1999 compared to 56 days in 1998.

General and administrative expense increased $1.1 million, to $2.2 million for
the quarter ended March 31, 1999. The increase is primarily due to a full
quarter of operations in the quarter ended March 31, 1999, and also reflects an
increase in personnel as a result of the increase in the number of Cabot Trust's
properties from 152 to 242 at the end of each quarter.

Interest and other income which consists primarily of interest earned on Cabot
Trust's invested cash balances and earnings of Cabot Advisors, decreased
$272,000 from $474,000 for the quarter ended March 31, 1998 to $202,000 for the
quarter ended March 31, 1999. The decrease is primarily due to a decrease in the
average invested cash balance for the quarter ended March 31, 1999.

Interest expense for the quarter ended March 31, 1999 represents interest
incurred on $149.8 million of mortgage indebtedness outstanding at March 31,
1999, and interest on outstanding borrowings under Cabot Trust's Acquisition
Facility, net of $544,000 of interest capitalized to development projects.
Interest expense for 1998 was incurred for only 56 days on $13.4 million of
indebtedness.

During 1998 Cabot Trust entered into an interest rate hedge transaction
(referred to as a Treasury Lock) 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. At the March 31, 1999 contractual settlement date for this
transaction, Cabot Trust paid $2.5 million to its counter party in the
transaction, reflecting the decrease in Treasury security yields since the July
1998 commencement of the transaction. Because an offering of the size and
maturity contemplated when the interest rate hedge transaction was executed was
not completed by the time of, or shortly after, the March 31, 1999 settlement
date of the transaction, Cabot Trust recorded a loss related to the Settlement
of Treasury Lock of $2.5 million in the quarter ended March 31, 1999.

Minority interest expense represents net income allocable to holders of Cabot
L.P. Units. At March 31, 1999, Cabot Trust owned 92.9% of Cabot L.P.; therefore,
minority interest ownership was 7.1%. For the quarter ended March 31, 1998,
minority interest ownership was 57.2%. As discussed in Note 2 to the financial
statements, during the quarter ended March 31, 1999 a significant number of
Units were converted to Common Shares, resulting in a decreased minority
interest expense.

Capital Resources and Liquidity

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 equity financing when such financing
is available on attractive terms.

In March 1998 Cabot Trust established a $325, million unsecured revolving line
of credit facility (the Acquisition Facility) with Morgan Guaranty Trust Company
of New York as lead agent for a syndicate
<PAGE>
 
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 limits and
requirements for debt to asset ratios, debt service coverage minimums, 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, Cabot Trust has purchased approximately $50
million of real estate assets subsequent to March 31, 1999, and as of May 11,
1999 has commitments to purchase approximately $36 million of additional real
estate assets. Because a number of conditions must be met prior to the closing,
it is uncertain as to whether all these assets will actually be purchased. The
completed real estate asset acquisitions were primarily funded through
Acquisition Facility borrowings and proceeds from the unsecured debt offering
described below.

Cabot Trust also has agreements to sell two buildings for an aggregate sales
price of approximately $17 million. These sales are expected to result in a net
gain of approximately $3.4 million for one transaction, and a net loss of
approximately $700,000 for the other. Because the sales are subject to a number
of conditions that must be met prior to closing, it is uncertain as to whether
these sales will actually be consummated.

As of March 31, 1999, Cabot L.P. had $149.8 million of fixed rate debt secured
by properties, $211 million of unsecured borrowings under its Acquisition
Facility and a 30.5% 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. Cabot Trust
has entered into an interest rate cap arrangement relating to its LIBOR-based
Acquisition Facility for a notional amount of $124 million for the period
March 19, 1999 through June 19, 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 5.35% per annum.

On April 29, 1999, Cabot L.P. completed a private sale of $65 million of 8.625%
Series B Cumulative Redeemable Perpetual Preferred Units at $50 per unit.
Proceeds of the offering were used to repay borrowings under Cabot Trust's
Acquisition Facility. The Preferred Units, which may be called by Cabot Trust at
par on or after April 29, 2004, have no stated maturity or mandatory redemption
and are not convertible into any other securities of Cabot L.P.

On May 4, 1999, Cabot L.P. completed a $200 million senior unsecured debt
offering. The debt has a maturity of five years, a coupon rate of 7.125% and
was priced at 99.724%, resulting in a yield to maturity of 7.192%. The net
proceeds of the offering were $197.2 million and were used in part to repay
borrowings under Cabot Trust's Acquisition Facility.

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 

<PAGE>
 
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.

Cash and cash equivalents totaled $34.6 million at March 31, 1999. Cash provided
by operating activities for the three months ended March 31, 1999, was $20.8
million.
