1.  General

Organization

Cabot Industrial Properties, L.P. (Cabot L.P.), a Delaware limited
partnership, was formed on October 10, 1997.  The general partner of Cabot L.P.
is Cabot Industrial Trust (Cabot Trust), a Maryland real estate investment
trust which was also formed on October 10, 1997.  As the general partner of
Cabot L.P., Cabot Trust has the exclusive power under the Cabot L.P. limited
partnership agreement to manage and conduct the business of Cabot L.P. Cabot
Trust is a fully-integrated, internally-managed real estate company formed to
continue and expand the national real estate business of Cabot Partners Limited
Partnership (Cabot Partners).

Since Cabot L.P. was formed on October 10, 1997, and did not begin operations
until February 4, 1998 (see Note 2), the results for the six months ended June
30, 1998 represent activity for 147 days, or approximately 5 months.

As of June 30, 1999, Cabot L.P. owned 267 industrial properties located in 21
markets throughout the United States and containing approximately 32 million
rentable square feet.  These properties were approximately 97.6% leased to 534
tenants at June 30, 1999.

2.   The Formation Transactions, The Offerings and Ownership

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 of Cabot Trust.
The properties contributed to Cabot Trust were each 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
L.P.

During the six months ended June 30, 1999, Cabot L.P. issued 143,087 Units in
conjunction with an acquisition and Cabot Trust issued 22,032,656 Common Shares
in exchange for Units of Cabot L.P.  As a result, Cabot Trust owned 93.1% of the
common equity of Cabot L.P. as of June 30, 1999.  The remaining 6.9% is owned by
investors holding Cabot L.P. Units.

The Offerings

On February 4, 1998, Cabot Trust completed an 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 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.

4.    Debt Activity

On May 4, 1999, Cabot L.P. completed a $200.0 million 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 $197.4 million and were used in part to repay borrowings under
Cabot L.P.'s Acquisition Facility.

In conjunction with acquisitions made during the six months ended June 30, 1999,
Cabot L.P. assumed debt of $19.1 million, with coupon interest rates ranging
from 7.375% to 9.375%, secured by properties with a net book value of
approximately $33.2 million. In addition, Cabot L.P. borrowed $87.6 million in
February 1999 and borrowed an additional $5.6 million under the same agreement
in April 1999, all secured by specific properties. At June 30, 1999, these
properties had a net book value of $136.6 million. 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 the
remaining balance outstanding is due at the end of the 10-year term. 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
L.P.'s Acquisition Facility.

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

5. Earnings per Unit

In accordance with Statement of Financial Accounting Standards No. 128,
"Earnings per Share", basic earnings per Partnership unit have been computed by
dividing net income allocable to Partnership unitholders by the weighted average
number of Partnership units outstanding during the period subsequent to Cabot
L.P.'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 Partnership unit were
calculated as follows:

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
expectations, estimates and projections about the industry and markets in which
Cabot L.P. operates, management's beliefs and assumptions made by management.
Words such as "expects," "anticipates," "intends," "plans," "believes," "seeks,"
"estimates" and variations of such words and similar expressions are intended to
identify such forward-looking statements.  Such forward-looking statements are
not guarantees of future performance and involve risks and uncertainties.
Therefore, actual outcomes and results may differ materially from what is
expressed or suggested by such forward-looking statements.  Cabot L.P.
undertakes no obligation to update publicly any forward-looking statements,
whether as a result of new information, future events or otherwise.  Cabot
L.P.'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 L.P.'s cost of capital also influence operating
results.

Introduction

Cabot L.P. 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 L.P. owns and operates a diversified
portfolio of bulk distribution, multitenant distribution and "workspace" (light
industrial, R&D and similar facilities) properties throughout the United States.
At June 30, 1999, Cabot L.P. owned 267 industrial properties, 60 of which
properties were acquired during the period from January 1, 1999 through June 30,
1999. Cabot L.P. sold one property on June 22, 1999. Cabot L.P. was formed on
October 10, 1997, but did not begin operations as a fully integrated real estate
company until the completion of its Formation Transactions and Offerings on
February 4, 1998, the date of Cabot Trust's initial public offering.

Results of Operations

Since Cabot L.P. did not begin operations until February 4, 1998, the results
for the six months ended June 30, 1998 represent activity for only 147 days.

Quarter Ended June 30, 1999 compared with Quarter Ended June 30, 1998

Net income allocable to Partnership unitholders for the quarter ended June 30,
1999, totaled $17.7 million or $.41 per unit, compared with $14.2 million or
$.33 per unit for the quarter ended June 30, 1998. The increase of 24% in net
income allocable to Partnership unitholders was primarily due to the income
realized from increased investment in real estate assets, as well as increased
earnings from Baseline Properties.

Rental revenues were $37.2 million, including tenant reimbursements of $5.2
million, for the quarter ended June 30, 1999, compared with $26.2 million,
including tenant reimbursements of $3.3 million, for the quarter ended June 30,
1998. Total rental revenue of $26.4 million and $25.1 million was generated in
1999 and 1998, respectively, by the properties owned as of March 31, 1998 and
still owned at June 30, 1999, (the Quarterly Baseline Properties) and total
rental revenue $10.5 million and $619,000 in 1999 and 1998, respectively, was
generated by

<PAGE>
the properties acquired or developed subsequent to March 31, 1998. The
growth in rental revenue for Quarterly Baseline Properties is primarily
attributable to rental increases for new leases (including extensions and
renewals). The remainder of total rental revenue relates to properties sold in
1998 and 1999.

The operating margin (the ratio of total revenues minus property operating and
real estate tax expenses to total revenues) was relatively unchanged at
approximately 82% for the quarter ended June 30, 1999 compared to 83% for the
quarter ended June 30, 1998.

Depreciation and amortization related to real estate assets totaled $7.3 million
and $5.1 million for the quarters ended June 30, 1999 and 1998, respectively.
The increase reflects the acquisition of real estate assets and additional
deferred lease acquisition costs for Baseline Properties.

General and administrative expense increased by $414,000, to $2.1 million for
the quarter ended June 30, 1999. The increase is primarily due to an increase in
personnel to service the increase in the number of Cabot L.P.'s properties from
171 to 267 at the end of each period.

Interest expense grew, from $797,000 for the quarter ended June 30, 1998 to $5.8
million for the quarter ended June 30, 1999. The increase is the result of
increased debt outstanding which was used primarily to fund real estate
acquisitions. For the quarter ended June 30, 1998, Cabot L.P. had $68.0 million
of debt outstanding under its Acquisition Facility and $17.5 million of
outstanding mortgage debt. For the quarter ended June 30, 1999, Cabot L.P. had
$4.0 million of debt outstanding under its Acquisition Facility, $159.1 million
of outstanding mortgage debt and $200.0 million of unsecured debt outstanding,
that was issued on May 4, 1999.

Interest and other income, which consists primarily of interest earned on Cabot
L.P.'s invested cash balances and earnings of Cabot Advisors, increased to
$304,000 from $248,000 for the quarter ended June 30, 1999, compared to the
quarter ended June 30, 1998.  The increase is primarily the result of increased
average investment balances.

On June 22, 1999, Cabot L.P. sold one property located in Massachusetts
containing approximately 120,000 square feet for an aggregate sales price of
approximately $10.5 million, which resulted in a gain of approximately $3.4
million.

Six Months Ended June 30, 1999 compared with Six Months Ended June 30, 1998

Net income allocable to Partnership unitholders for the six months ended June
30, 1999, totaled $29.7 million or $.68 per unit, compared with $22.4 million or
$.51 per unit for the six months ended June 30, 1998. The increase in net income
allocable to Partnership unitholders is due to a full six months of operations
in 1999 compared with 147 days in 1998 and increased earnings due primarily to
increased investment in real estate assets, as well as increased earnings from
Baseline Properties.

Rental revenues were $71.3 million, including tenant reimbursements of $10.1
million, for the six months ended June 30, 1999, compared with $40.9 million,
including tenant reimbursements of $5.2 million, for the six months ended June
30, 1998. Total rental revenue of $41.7 million and $32.5 million was generated
in 1999 and 1998, respectively, by the 120 properties owned as of February 4,
1998 and still owned at June 30, 1999 (the Baseline Properties) and total rental
revenue of $29.2 million and $7.6 million in 1999 and 1998, respectively,

<PAGE>

was generated by the 147 properties acquired or developed subsequent to February
4, 1998. The remainder of total rental revenue relates to properties sold in
1998 and 1999. The increase in rental revenue related to the Baseline Properties
is primarily the result of 181 compared to 147 days of activity, as well as
rental increases achieved on new leases (including extensions and renewals).

Depreciation and amortization related to real estate assets totaled $14.1
million and $8.2 million for the six months ended June 30, 1999 and 1998,
respectively.  The increase reflects the acquisition of real estate assets and
181 days of operations in 1999 compared to 147 days in 1998.

General and administrative expense increased by $1.5 million, to $4.3 million
for the six months ended June 30, 1999. The increase is primarily due to a full
six months of operations in the six months ended June 30, 1999, and also
reflects an increase in personnel to service the increase in the number of
Cabot L.P.'s properties from 171 to 267 at the end of each period.

Interest expense for the six months ended June 30, 1999 of $10.1 million
represents interest incurred on the $200.0 million of unsecured debt and the
$159.1 million of mortgage indebtedness outstanding at June 30, 1999, and
interest on outstanding borrowings under Cabot L.P.'s Acquisition Facility, net
of $1.3 million of interest capitalized to development projects. Interest
expense of $1.0 million for 1998 was incurred for only 147 days, and was
incurred on $68.0 million of indebtedness under the Acquisition Facility and
$17.5 million of secured debt outstanding on June 30, 1998.

During 1998 Cabot L.P. entered into an interest rate hedge transaction (referred
to as a Treasury Lock) involving the future sale of $100.0 million of Treasury
securities based on a rate of approximately 5.54% for such securities in
anticipation of a future debt issuance of at least $100.0 million with a
maturity of 10 years.  At the March 31, 1999 contractual settlement date for
this transaction, Cabot L.P. paid $2.5 million to its counter party in the
transaction, reflecting the decrease in Treasury security yields since the July
1998 commencement of the transaction.  Because an offering of the size and
maturity contemplated when the interest rate hedge transaction was executed was
not completed by the time of, or shortly after, the March 31, 1999 settlement
date of the transaction, Cabot L.P. recorded a loss related to the Settlement of
Treasury Lock of $2.5 million in the quarter ended March 31, 1999, which is
reflected in the six months ended June 30, 1999.

Interest and other income, which consists primarily of interest earned on Cabot
L.P.'s invested cash balances and earnings of Cabot Advisors, decreased $216,000
from $722,000 for the six months ended June 30, 1998 to $506,000 for the six
months ended June 30, 1999, due primarily to lower average invested cash
balances.

Capital Resources and Liquidity

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

In March 1998 Cabot L.P. 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 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
<PAGE>

minimums, and other limitations. Cabot L.P. believes cash flow from operations
not distributed to 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 L.P. has purchased approximately $30
million of real estate assets subsequent to June 30, 1999, and as of July 31,
1999, has commitments to purchase approximately $90 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.

Subsequent to June 30, 1999, Cabot L.P. sold one building for an aggregate sales
price of approximately $6.6 million. This sale is expected to result in a net
loss of approximately $700,000.

As of June 30, 1999, Cabot L.P. had $159.1 million of fixed rate debt secured by
properties, $4.0 million of unsecured borrowings under its Acquisition Facility,
$200.0 million of unsecured debt, and a 27% debt-to-total market capitalization
ratio.  The debt-to-total market capitalization ratio is calculated based on
Cabot L.P.'s total consolidated debt as a percentage of the market value of its
outstanding Partnership Units and the liquidation value of Perpetual Preferred
Units plus total debt.

Cabot L.P. 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 was intended to result in
limiting the LIBOR component of Cabot L.P.'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 L.P.'s
Acquisition Facility.  The Preferred Units, which may be called by Cabot L.P. 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 $200.0 million 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 $197.4 million and were used in part to repay borrowings under
Cabot L.P.'s Acquisition Facility.

Cash and cash equivalents totaled $827,000 at June 30, 1999. Cash provided by
operating activities for the six months ended June 30, 1999, was $44.8 million.

Cabot L.P. has assessed its Year 2000 readiness with respect to its internal
accounting and information systems. Cabot L.P. 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 L.P. No significant
issues or costs of remediation have been identified with respect to such systems
or vendors. Cabot L.P. 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 that review, none of which are
considered by Cabot L.P. to be material. Remediation costs to date have not been
material and Cabot L.P. 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 industrial real estate assets and the general nature
of its leases, which in many instances provide for the reimbursement of costs
from its tenants. Cabot L.P. believes that there will
<PAGE>

be no direct material effects on its operating performance or results of
operations from the Year 2000 problem as it relates to Cabot L.P.'s internal
systems and significant vendors. Cabot L.P. 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 L.P. conducts its business.
