See accompanying notes to financial statements. 5 CORPORATE OFFICE PROPERTIES TRUST AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA) (UNAUDITED) 1. ORGANIZATION Corporate Office Properties Trust ("COPT") and subsidiaries (collectively, the "Company") is a fully-integrated and self-managed real estate investment trust ("REIT"). We focus principally on the ownership, management, leasing, acquisition and development of suburban office properties located in select submarkets in the Mid-Atlantic region of the United States. COPT is qualified as a REIT as defined in the Internal Revenue Code and is the successor to a corporation organized in 1988. As of June 30, 2002, our portfolio included 108 office properties. We conduct almost all of our operations principally through our operating partnership, Corporate Office Properties, L.P. (the "Operating Partnership"), for which we are the managing general partner. The Operating Partnership owns real estate both directly and through subsidiary partnerships and limited liability companies ("LLCs"). The Operating Partnership also owns Corporate Office Management, Inc. ("COMI") (together with its subsidiaries defined as the "Service Companies"). A summary of our Operating Partnership's classes of securities and the percentage of the outstanding units of each class owned by COPT as of June 30, 2002 follows:

% Owned by COPT ---------- Common Units 70% Series B Preferred Units 100% Series C Preferred Units 0% Series D Preferred Units 100% Series E Preferred Units 100% Series F Preferred Units 100%

2. BASIS OF PRESENTATION The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the rules and regulations for reporting on Form 10-Q. Accordingly, certain information and disclosures required by accounting principles generally accepted in the United States for complete consolidated financial statements are not included herein. These interim financial statements should be read together with the financial statements and notes thereto included in our 2001 Annual Report on Form 10-K. The interim financial statements on the previous pages reflect all adjustments which we believe are necessary for the fair presentation of our financial position and results of operations for the interim periods presented. These adjustments are of a normal recurring nature. The results of operations for such interim periods are not necessarily indicative of the results for a full year. We use three different accounting methods to report our investments in entities: the consolidation method, the equity method and the cost method. CONSOLIDATION METHOD We use the consolidation method when we own most of the outstanding voting interests in an entity and can control its operations. This means the accounts of the entity are combined with our accounts. We eliminate balances and transactions between companies when we consolidate these accounts. Our consolidated financial statements include the accounts of: - - COPT; - - the Operating Partnership and its subsidiary partnerships and LLCs; and - - Corporate Office Properties Holdings, Inc. (of which we own 100%). 6 EQUITY METHOD We use the equity method of accounting when we own an interest in an entity and can exert significant influence over the entity's operations but cannot control the entity's operations. Under the equity method, we report: - our ownership interest in the entity's capital as an investment on our Consolidated Balance Sheets and - our percentage share of the earnings or losses from the entity in our Consolidated Statements of Operations. COST METHOD We use the cost method of accounting when we own an interest in an entity and cannot exert significant influence over the entity's operations. Under the cost method, we report: - the cost of our investment in the entity as an investment on our Consolidated Balance Sheets and - distributions to us of the entity's earnings in our Consolidated Statements of Operations. RECLASSIFICATION We reclassified certain amounts from the prior period to conform to the current period presentation of our consolidated financial statements. These reclassifications did not affect consolidated net income or shareholders' equity. In the first quarter of 2002, we sold a land parcel and an interest in a real estate joint venture; the income and gains on sale derived from these assets were classified as discontinued operations in the first quarter's Form 10-Q filed with the Securities and Exchange Commission. In the Consolidated Statements of Operations included herein, we reclassified the income earned from the real estate joint venture prior to its sale from the line entitled discontinued operations to the line entitled equity in (loss) income of unconsolidated real estate joint ventures; we also reclassified the gain on sales of these assets from the line entitled discontinued operations to the line entitled gain on sales of real estate. These reclassifications increased income before discontinued operations, extraordinary item and cumulative effect of accounting change by $656 from what was originally reported but did not affect consolidated net income or earnings per share on net income available to Common Shareholder. The reclassifications were made as a result of recent interpretations of Statements of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS We make estimates and assumptions when preparing financial statements under generally accepted accounting principles. These estimates and assumptions affect various matters, including: - our reported amounts of assets and liabilities in our Consolidated Balance Sheets at the dates of the financial statements; - our disclosure of contingent assets and liabilities at the dates of the financial statements; and - our reported amounts of revenues and expenses in our Consolidated Statements of Operations during the reporting periods. These estimates involve judgments with respect to, among other things, future economic factors that are difficult to predict and are often beyond management's control. As a result, actual amounts could differ from these estimates. MINORITY INTERESTS As discussed previously, we consolidate the accounts of our Operating Partnership and its subsidiaries into our financial statements. However, we do not own 100% of the Operating Partnership. Our Operating Partnership also does not own 11% of one of its subsidiary partnerships. In addition, COMI did not own 20% of one of its subsidiaries, Martin G. Knott and Associates, LLC, until May 31, 2002, when it acquired that remaining interest. The amounts reported for minority interests on our Consolidated Balance Sheets represent the portion of these consolidated entities' equity that we do not own. The amounts reported for minority interests on our Consolidated Statements of Operations represent the portion of these consolidated entities' net income not allocated to us. 7 EARNINGS PER SHARE We present both basic and diluted earnings per Common Share ("EPS"). We compute basic EPS by dividing income available to common shareholders by the weighted-average number of Common Shares of beneficial interest ("Common Shares") outstanding during the period. Our computation of diluted EPS is similar except that: - - the denominator is increased to include the weighted-average number of potential additional Common Shares that would have been outstanding if securities that are convertible into our Common Shares were converted; and - - the numerator is adjusted to add back any convertible preferred dividends and any other changes in income or loss that would result from the assumed conversion into Common Shares. 8 Our computation of diluted EPS does not assume conversion of securities into our Common Shares if conversion of those securities would increase our diluted EPS in a given period. A summary of the numerator and denominator for purposes of basic and diluted EPS calculations is as follows (in thousands, except per share data):

Our diluted EPS computation assumes only conversion of share options and Series D Cumulative Convertible Redeemable Preferred Shares of beneficial interest (the "Series D Preferred Shares") because conversions of Preferred Units, Series A Convertible Preferred Shares of beneficial interest (the "Series A Preferred Shares") and Common Units would increase diluted EPS in the periods presented. 9 RECENT ACCOUNTING PRONOUNCEMENTS On July 1, 2001 and January 1, 2002, we adopted Statement of Financial Accounting Standards No. 141 "Business Combinations" ("SFAS 141") and No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142"), respectively. SFAS 141 requires that the purchase method of accounting be used for all business combinations initiated after June 30, 2001. The provisions of SFAS 142 require that (1) amortization of goodwill, including goodwill recorded in past business combinations, be discontinued upon adoption of this standard and (2) goodwill be tested annually for impairment and in interim periods if certain events occur indicating that the carrying value of goodwill may be impaired. After completing an evaluation of our unamortized goodwill under the provisions of SFAS 142, we concluded that our carrying value of goodwill was not impaired as of January 1, 2002 and June 30, 2002. The following table summarizes our goodwill amortization and operating results as if goodwill amortization did not occur. Basic and diluted earnings per Common Share on net income available to Common Shareholders reported on our Consolidated Statements of Operations would not have changed if goodwill amortization did not occur in the 2001 periods reported herein.

Three months ended Six months ended June 30, June 30, -------------------- -------------------- 2002 2001 2002 2001 ------- ------- ------- ------- Amortization of goodwill $ -- $ 44 $ -- $ 84 Amortization of goodwill, net of minority interests and income taxes $ -- $ 17 $ -- $ 33 Income before extraordinary item and cumulative effect of accounting change, as reported $ 5,993 $ 5,147 $11,316 $ 9,117 Income before extraordinary item and cumulative effect of accounting change, exclusive of goodwill amortization $ 5,993 $ 5,164 $11,316 $ 9,150 Net income available to Common Shareholders, as reported $ 3,350 $ 3,468 $ 6,112 $ 6,313 Net income available to Common Shareholders, exclusive of goodwill amortization $ 3,350 $ 3,485 $ 6,112 $ 6,346

In January 1, 2002, we adopted Statement of Financial Accounting Standards No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS 144"). SFAS 144 provides new guidance on recognition of impairment losses on long-lived assets to be held and used and broadens the definition of what constitutes a discontinued operation and how the results of discontinued operations are to be measured. The primary impact of our adoption of this standard is that revenues and expenses associated with our property held for sale at June 30, 2002 are classified as discontinued operations on our Consolidated Statements of Operations for the periods reported. In April 2002, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 145, "Rescission of FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections" ("SFAS No. 145"). SFAS 145 generally eliminates the requirement that gains and losses from the extinguishment of debt be aggregated and, if material, classified as an extraordinary item, net of the related income tax effect. SFAS 145 also eliminates previously existing inconsistencies between the accounting for sale-leaseback transactions and certain lease modifications that have economic effects similar to that of sale-leaseback transactions. The amendment requires that lease modifications result in recognition of a gain or loss in the financial statements and, where applicable, be subject to existing accounting standards governing sales of real estate and sale-leaseback transactions. SFAS 145 is effective for us on January 1, 2003, although certain aspects of the standard are effective for transactions occurring after May 15, 2002. SFAS 145 also requires that gains or losses from extinguishment of debt reported as an extraordinary item in prior periods presented be reclassified upon adoption. We expect the only impact of adoption on January 1, 2003 will be the reclassification of all prior period losses on early retirement of debt from the line on the Consolidated Statements of Operations entitled "extraordinary item" to the line entitled "amortization of deferred financing costs". These reclassifications will not result in changes to net income available to Common Shareholders or basic and diluted 10 earnings per Common Share on net income available to Common Shareholders. The following table summarizes our early extinguishment of debt and change to the line entitled "income before extraordinary item and cumulative effect of accounting change" as if such reclassifications were made for the periods reported herein.

ACQUISITIONS We acquired the following office properties during the six months ended June 30, 2002:

Total Date of Number of Rentable Project Name Location Acquisition Buildings Square Feet Initial Cost --------------------------- ------------ ----------- --------- ----------- ------------ 7320 Parkway Drive Hanover, MD 4/4/02 1 57,176 $ 4,957 Rivers 95 Columbia, MD 4/4/02 4 109,449 11,562 7000 Columbia Gateway Drive Columbia, MD 5/31/02 1 145,806 16,196

On January 31, 2002, we acquired a parcel of land located in Annapolis Junction, Maryland for $3,757 from an affiliate of Constellation Real Estate, Inc. ("Constellation"). On the date of this transaction, Constellation owned 43% of our Common Shares and had the right to designate nominees for two of the eight positions on our Board of Trustees (see Note 10). 2002 CONSTRUCTION/DEVELOPMENT During the six months ended June 30, 2002, we completed the construction of three office buildings totaling 279,167 square feet. The buildings are located in the Baltimore/Washington Corridor. As of June 30, 2002, we also had construction underway on three new buildings. 2002 DISPOSITION We sold a land parcel located in Hanover, Maryland for $1,300 on March 29, 2002. We realized a gain of $597 on the sale of this property. ACCOUNTING FOR CERTAIN REAL ESTATE JOINT VENTURES Prior to 2002, we contributed parcels of land into two real estate joint ventures. In exchange for the contributions of land, we received joint venture interests and $9,600 in cash. Each of these joint ventures constructed office buildings on the land parcels. Each of the joint ventures' operating agreements provided us with the option to acquire the joint venture partners' interests for a pre-determined purchase price over a limited period of time. In February 2002, we acquired the joint venture partner's interest in one of these joint ventures for the pre-determined purchase price of $5,448. In June 2002, we acquired the joint venture partner's interest in the other joint venture for the pre-determined purchase price of $6,361. For periods prior to acquiring the joint venture partners' interests, we accounted for our interests in these joint ventures as follows: - - the costs associated with these land parcels at the time of their respective contributions were reported as commercial real estate properties on our Consolidated Balance Sheets; - - the cash received from these joint ventures in connection with the land contributions was reported as other liabilities on our Consolidated Balance Sheets. These liabilities were accreted towards the pre-determined purchase price over the life of our option to acquire the joint venture partners' interests. We also reported interest expense in connection with the accretion of these liabilities; - - as construction of the buildings on these land parcels was completed and operations commenced, we reported 100% of the revenues and expenses associated with these properties on our Consolidated Statements of Operations; and 12 - - construction costs and debt activity for these projects relating to periods after the respective land contributions were not reported by us. Upon completion of these acquisitions, we began consolidating the accounts of the entities with our accounts. 5. INVESTMENTS IN AND ADVANCES TO UNCONSOLIDATED REAL ESTATE JOINT VENTURES On February 21, 2002, we acquired the remaining 20% interest in MOR Montpelier LLC not previously owned by us and simultaneously sold the 43,785 square foot building owned by that entity, realizing a gain of $352. On February 21, 2002, we also acquired a 50% interest in MOR Montpelier 3 LLC, an entity developing a parcel of land located in Columbia, Maryland. Our investments in and advances to unconsolidated real estate joint ventures are accounted for using the equity method of accounting and include the following:

June 30, December 31, 2002 2001 ------------ ------------ Gateway 67, LLC $ 4,043 $ 3,904 NBP 140, LLC 3,851(1) 2,885(1) Gateway 70 LLC 2,409 2,326 MOR Forbes LLC 907 924 MOR Montpelier 3 LLC 298 -- MOR Montpelier LLC -- 1,008 ------------ ------------ $ 11,508 $ 11,047 ============ ============

(1)Includes a mortgage loan receivable of $3,113 at June 30, 2002 and $2,640 at December 31, 2001 carrying an annual interest rate of Prime through its maturity on December 27, 2002. We have additional commitments pertaining to our real estate joint ventures that are disclosed in Note 16. The following table sets forth condensed combined balance sheet information for these unconsolidated real estate joint ventures:

June 30, December 31, 2002 2001 ---------- ------------ Commercial real estate property $ 24,574 $ 27,869 Other assets 861 1,566 --------- ------------ Total assets $ 25,435 $ 29,435 ========= ============ Liabilities $ 15,904 $ 18,935 Owners' equity 9,531 10,500 --------- ------------ Total liabilities and owners' equity $ 25,435 $ 29,435 ========= ============

6. ACCOUNTS RECEIVABLE Our accounts receivable are reported net of an allowance for bad debts of $731 at June 30, 2002 and $723 at December 31, 2001. 13 7. INVESTMENTS IN AND ADVANCES TO OTHER UNCONSOLIDATED ENTITIES Our investments in and advances to other unconsolidated entities include the following:

June 30, December 31, 2002 2001 ------------ ------------ MediTract, LLC $ 1,621 $ 1,621 Paragon Smart Technologies, LLC (1) 486 491 ------------ ------------ Total $ 2,107 $ 2,112 ============ ============

(1) Investment includes $245 in notes receivable carrying an interest rate of 12% per annum that are payable on demand. 8. DEFERRED CHARGES Deferred charges consist of the following:

June 30, December 31, 2002 2001 ------------ ------------ Leasing costs $ 17,691 $ 13,298 Financing costs 10,777 9,599 Goodwill 1,465 1,320 Other intangible costs 154 154 ------------ ------------ 30,087 24,371 Accumulated amortization (1) (10,210) (7,487) ------------ ------------ Deferred charges, net $ 19,877 $ 16,884 ============ ============

(1) Includes accumulated amortization associated with other intangibles of $147 at June 30, 2002 and $132 at December 31, 2001. 9. DERIVATIVES The following table sets forth derivative contracts we had in place and their respective fair market values ("FMV"):

FMV ------------------------- Notional Nature of Amount One-Month Effective Expiration June 30, December 31, Derivative (in millions) LIBOR base Date Date 2002 2001 - ----------------- --------------- ------------- ----------- ------------ ---------- ------------- Interest rate swap $ 100.0 5.76% 1/2/01 1/2/03 $ (1,970) $ (3,781) Interest rate cap 50.0 7.70% 5/25/00 5/31/02 -- -- --------- ---------- Total $ (1,970) $ (3,781) ========= ==========

We designated each of these derivatives as cash flow hedges. At June 30, 2002, the interest rate swap is effective. During the six months ended June 30, 2002, we decreased the negative balance in the accumulated other comprehensive loss component of shareholders' equity ("AOCL") and increased minority interests in total by $1,813 to recognize the increase in the fair value of the interest rate swap during that period. Over time, the unrealized loss held in AOCL and minority interests associated with our interest rate swap will be reclassified to earnings. Within the next six months, we expect to reclassify to earnings an estimated $2.0 million of the balances held in AOCL and minority interests. 10. SHAREHOLDERS' EQUITY On March 5, 2002, we participated in an offering of 10,961,000 Common Shares to the public at a price of $12.04 per share; Constellation was the owner of 8,876,172 of these shares and 2,084,828 of these shares were newly issued by us. With the completion of this transaction, Constellation, which had been our largest Common 14 shareholder, is no longer a shareholder. We contributed the net proceeds from the sale of the newly-issued shares to our Operating Partnership in exchange for 2,084,828 Common Units. Also on March 5, 2002, Constellation converted its one remaining series A Preferred Share into 1.8748 Common Shares. As holder of the Series A Preferred Share, Constellation had the right to nominate two members for election to our Board of Trustees; with the conversion of its Series A Preferred Share into Common Shares, Constellation no longer has that right. Constellation sold one of these Common Shares and we redeemed the fractional share. On December 16, 1999, we issued 471,875 Common Shares subject to forfeiture restrictions to certain officers; we issued an additional 12,500 Common Shares to an officer in 2000 that were subject to the same restrictions. The forfeiture restrictions of specified percentages of these shares lapse annually through 2004 provided that the officers remain employed by us and we attain defined earnings or shareholder return growth targets. These shares may not be sold, transferred or encumbered while the forfeiture restrictions are in place. Forfeiture restrictions lapsed on 72,659 of these shares in 2002. During the six months ended June 30, 2002, 329,142 Common Units in our Operating Partnership were converted into Common Shares on the basis of one Common Share for each Common Unit. We issued 173,726 Common Shares in connection with the exercise of share options during the six months ended June 30, 2002. A summary of the activity in the accumulated other comprehensive loss component of shareholders' equity for the six months ended June 30, 2002 follows: Balance, December 31, 2001 $2,500 Unrealized gain on interest rate swap for the six months ended June 30, 2002, net of minority interests (1,226) ------ Balance, June 30, 2002 $1,274 ====== The components of comprehensive income for the three and six month ended June 30, 2002 and 2001 follow:

INFORMATION BY BUSINESS SEGMENT We have five office property segments: Baltimore/Washington Corridor, Greater Philadelphia, Northern/Central New Jersey, Greater Harrisburg and Northern Virginia. The table below reports segment financial information. Our segment entitled "Other" includes other assets and operations not specifically associated with the other defined segments (including deferred goodwill and other intangible deferred costs). We measure the performance of our segments based on total revenues less property operating expenses. Accordingly, we do not report other expenses by segment in the table below.

Three Months Ended Six Months Ended June 30, June 30, ----------------------------- --------------------------- 2002 2001 2002 2001 ------------- ------------- ----------- ------------- Income from operations for reportable segments $ 26,481 $ 20,353 $ 50,790 $ 41,588 Equity in (loss) income of unconsolidated real estate joint ventures (22) 124 (4) 154 (Losses) earnings from service operations (104) 143 (194) (186) Add: Gain on sales of properties -- 1,596 946 1,596 Less: General and administrative (1,940) (1,329) (4,110) (2,775) Interest (9,002) (7,680) (17,569) (15,792) Amortization of deferred financing costs (549) (546) (1,035) (929) Depreciation and other amortization (6,707) (4,914) (13,348) (9,755) Minority interests (2,061) (2,425) (3,972) (4,523) Income from real estate operations included in discontinued operations (238) (188) (414) (405) ------------- ------------- ----------- ------------- Income before income taxes, discontinued operations, extraordinary item and cumulative effect of accounting change $ 5,858 $ 5,134 $ 11,090 $ 8,973 ============= ============= =========== =============

We did not allocate interest expense, amortization of deferred financing costs and depreciation and other amortization to segments since they are not included in the measure of segment profit reviewed by management. We also did not allocate equity in (loss) income of unconsolidated real estate joint ventures, (losses) earnings from service operations, general and administrative expense and minority interests since these items represent general corporate expenses not attributable to segments. 14. INCOME TAXES COMI's provision for income tax benefit consists of the following:

For the six months ended June 30, ---------------------------- 2002 2001 ------------- ------------ Current Federal $ (10) $ 15 State (2) 3 ------------- ------------ (12) 18 ------------- ------------ Deferred Federal 73 50 State 16 10 ------------- ------------ 89 60 ------------- ------------ Income tax benefit 77 78 Less: minority interests (25) (26) ------------- ------------ Income tax benefit, net of minority interests $ 52 $ 52 ============= ============

Items contributing to temporary differences that lead to deferred taxes include depreciation and amortization, certain accrued compensation, compensation made in the form of contributions to a deferred nonqualified compensation plan and expenses associated with share options. COMI's combined Federal and state effective tax rate for the six months ended June 30, 2002 and 2001 was approximately 40%. 19 15. DISCONTINUED OPERATIONS Discontinued operations includes revenues and expenses associated with our property located at 8815 Centre Park Drive in Columbia, Maryland, which is classified as held for sale at June 30, 2002. The table below sets forth the components of income from discontinued operations.

16. COMMITMENTS AND CONTINGENCIES In the normal course of business, we are involved in legal actions arising from our ownership and administration of properties. Management does not anticipate that any liabilities that may result will have a materially adverse effect on our financial position, operations or liquidity. We are subject to various Federal, state and local environmental regulations related to our property ownership and operation. We have performed environmental assessments of all of our properties, the results of which have not revealed any environmental liability that we believe would have a materially adverse effect on our financial position, operations or liquidity. We may need to make our share of additional investments in our real estate joint ventures (generally based on our percentage ownership) in the event that additional funds are needed. In the event that the other members of these joint ventures do not pay their share of investments when additional funds are needed, we may then need to make even larger investments in these joint ventures. As of June 30, 2002, we served as guarantor for the repayment of mortgage loans totaling $7,809 for certain of our unconsolidated real estate joint ventures. In four of our five joint ventures, we would be obligated to acquire the membership interests of those joint ventures not owned by us (20% in the case of three and 50% in the case of one) in the event that all of the following were to occur: (1) an 18-month period passes from the date that 85% of the square feet in the joint ventures' respective buildings become occupied (the "18-month period"); (2) at the end of the 18-month period, the joint ventures' respective buildings are 90% leased and occupied by tenants who are not in default under their leases; and (3) six months passes from the end of the 18-month period and either the buildings are not sold or we have not acquired the other members' interests. The amount we would need to pay for those membership interests is computed based on the amount that the owners of those interests would receive under the joint venture agreements in the event that the buildings were sold for a capitalized fair value (as defined in the agreements) on a defined date. At June 30, 2002, none of the buildings in these joint ventures have occupancy equal to or exceeding 85%. As of June 30, 2002, we are under contract to sell our property located at 8815 Centre Park Drive in Columbia, Maryland for $7,175. We completed the sale of this property on July 18, 2002. 20 17. PRO FORMA FINANCIAL INFORMATION We accounted for our 2001 and 2002 acquisitions using the purchase method of accounting. We included the results of operations for the acquisitions in our Consolidated Statements of Operations from their respective purchase dates through June 30, 2002. We prepared the pro forma condensed consolidated financial information presented below as if all of our 2001 and 2002 acquisitions and dispositions of operating properties had occurred on January 1, 2001. The pro forma financial information is unaudited and is not necessarily indicative of the results that actually would have occurred if these acquisitions and dispositions had occurred on January 1, 2001, nor does it intend to represent our results of operations for future periods.

Six months ended June 30, --------------------------- 2002 2001 ------------- ---------- Pro forma total revenues $ 73,929 $ 71,961 ============= ========== Pro forma net income available to Common Shareholders $ 6,475 $ 5,781 ============= ========== Pro forma earnings per Common Share Basic $ 0.30 $ 0.29 ============= ========== Diluted $ 0.28 $ 0.28 ============= ==========

18. SUBSEQUENT EVENTS ACQUISITIONS On July 18, 2002, we acquired for a purchase price of $3,600 a 32.8 acre land parcel in Chantilly, Virginia. On August 1, 2002, we acquired for a purchase price of $27,250 an office building totaling 236,441 square feet located in Silver Spring, Maryland. In July 2002, we became committed to acquire for a purchase price of $47,032 property in Chantilly, Virginia consisting of two office buildings totaling 290,245 square feet and a leasehold interest in an adjacent 6.3 acre land parcel. 21 ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS In this section, we discuss our financial condition and results of operations for the three and six months ended June 30, 2002. This section includes discussions on, among other things: - - why various components of our Consolidated Statements of Operations changed for the three and six months ended June 30, 2002 compared to the same periods in 2001; - - what our primary sources and uses of cash were in the six months ended June 30, 2002; - - how we raised cash for acquisitions and other capital expenditures during the six months ended June 30, 2002; - - how we intend to generate cash for short and long-term capital needs; and - - the computation of our funds from operations. You should refer to our consolidated financial statements and the operating data variance analysis table set forth below as you read this section. This section contains "forward-looking" statements, as defined in the Private Securities Litigation Reform Act of 1995, that are based on our current expectations, estimates and projections about future events and financial trends affecting the financial condition of our business. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. These statements are not guarantees of future performance, events or results and involve potential risks and uncertainties. Accordingly, actual results may differ materially from those addressed in the forward-looking statements. We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise. Important factors that may affect these expectations, estimates or projections include, but are not limited to: our ability to borrow on favorable terms; general economic and business conditions, which will, among other things, affect office property demand and rents, tenant creditworthiness, interest rates and financing availability; adverse changes in the real estate markets including, among other things, increased competition with other companies; risks of real estate acquisition and development; governmental actions and initiatives and environmental requirements. 22

23 RESULTS OF OPERATIONS COMPARISON OF THE THREE MONTHS ENDED JUNE 30, 2002 AND 2001 Our revenue from real estate operations increased $7.9 million or 27%, substantially all of which was attributable to rental revenue. Included in this change are the following: - $9.1 million increase attributable to 20 properties acquired and six newly-constructed properties placed in service since March 31, 2001; - $674,000 decrease attributable to 81 properties owned and operational throughout both reporting periods due primarily to decreased property occupancy and the write-off of additional deferred rents receivable upon early termination of leases; this represents a 2.5% decrease in total revenue for these properties; - $367,000 decrease attributable to properties sold; and - $208,000 decrease attributable to lower fees earned for other real estate services. Our expenses from real estate operations increased $4.9 million or 23% due to the effects of the increases in property operating expenses, interest expense and amortization of deferred financing costs and depreciation and other amortization described below. Our property operating expenses increased $1.8 million or 21%. Included in this change are the following: - $2.3 million increase attributable to 20 properties acquired and six newly-constructed properties placed in service since March 31, 2001; - $442,000 decrease attributable to 81 properties owned and operational throughout both reporting periods, a 5.4% decrease for these properties; this decrease includes the following: - $190,000 decrease in expense associated with doubtful or uncollectible receivables; - $103,000 decrease in exterior repair projects; - $102,000 decrease in cleaning due mostly to service no longer needed on vacated space; and - $101,000 increase in real estate taxes due to increased property assessments. - $86,000 decrease attributable to properties sold. Our interest expense and amortization of deferred financing costs increased $1.3 million or 16% due primarily to a 28% increase in our average outstanding debt balance resulting from our 2001 and 2002 acquisitions and construction activity, offset by a decrease in our weighted-average interest rates from 7.2% to 6.5%. Our depreciation and other amortization expense increased $1.8 million or 36%, $1.3 million of which is attributable to 20 properties acquired and six newly-constructed properties placed in service since March 31, 2001. Our general and administrative expense increased $611,000 or 46% due primarily to (i) additional employee bonus expense, (ii) increased expense associated with vesting of officer Common Share awards due to shares vesting at higher Common Share prices and (iii) increased corporate marketing costs. Income before minority interests, income taxes, discontinued operations, extraordinary item and cumulative effect of accounting change increased $360,000 or 5% primarily as a result of the above factors, offset by a $1.6 million decrease in gain from sales of real estate. The amounts reported for minority interests on our Consolidated Statements of Operations represent primarily the portion of the Operating Partnership's net income not allocated to us. Our income allocation to minority interests before giving effect to income tax benefit, discontinued operations, extraordinary item and cumulative effect of accounting change decreased $364,000 or 15%; this decrease is primarily attributable to the increase in our ownership of the Operating Partnership. 24 Our net income available to Common Shareholders decreased $118,000 or 3% reflecting the factors discussed above and a $921,000 increase in Preferred Share dividends resulting from our issuance of two new series of preferred shares since March 31, 2001. COMPARISON OF THE SIX MONTHS ENDED JUNE 30, 2002 AND 2001 Our revenue from real estate operations increased $12.7 million or 22%, which was substantially all attributable to rental revenue. Included in this change are the following: - $15.5 million increase attributable to 20 properties acquired and eight newly-constructed properties placed in service during 2001 and 2002; - $1.2 million decrease attributable to lower fees earned for other real estate services; - $1.0 million decrease attributable to 79 properties owned and operational throughout both reporting periods due primarily to a decrease in tenant recoveries, decreased property occupancy and the write-off of additional deferred rents receivable upon early termination of leases; this represents a 1.8% decrease in total revenue for these properties; and - $775,000 decrease attributable to properties sold during 2001. Our expenses from real estate operations increased $9.0 million or 21% due to the effects of the increases in property operating expenses, interest expense and amortization of deferred financing costs and depreciation and other amortization described below. Our property operating expenses increased $3.5 million or 21%. Included in this change are the following: - $4.5 million increase attributable to 20 properties acquired and eight newly-constructed properties placed in service during 2001 and 2002; - $792,000 decrease attributable to 79 properties owned and operational throughout both reporting periods, a 4.9% decrease for these properties; this decrease includes the following: - $447,000 decrease in utilities due in part to changes in lease structure, a result of which lead certain tenants to bear costs directly; - $440,000 decrease in snow removal due to less snow in 2002; - $203,000 decrease in cleaning due mostly to service no longer needed on vacated space; - $140,000 increase in real estate taxes due to increased property assessments; and - $129,000 increase in property administrative costs, which correlates with the increase in general and administrative expenses. - $204,000 decrease attributable to properties sold during 2001. Our interest expense and amortization of deferred financing costs increased $1.9 million or 11% due primarily to a 25% increase in our average outstanding debt balance resulting from our 2001 and 2002 acquisition and construction activity, offset by a decrease in our weighted-average interest rates from 7.5% to 6.5%. Our depreciation and other amortization expense increased $3.6 million or 37%, $2.7 million of which is attributable to 20 properties acquired and eight newly-constructed properties placed in service during 2001 and 2002. Our general and administrative expense increased $1.3 million or 48% due primarily to (i) additional employee bonus expense, including additional discretionary bonuses awarded to officers in the current period that were associated with performance in the prior year, (ii) increased expense associated with vesting of officer Common Share awards due to shares vesting at higher Common Share prices and (iii) increased expense associated with Common Share options that were re-priced in prior years and therefore subject to variable option accounting due to Common Share price appreciation. Income before minority interests, income taxes, discontinued operations, extraordinary item and cumulative effect of accounting change increased $1.6 million or 12% primarily as a result of the above factors, offset by a $650,000 decrease in gain from sales of real estate. Our income allocation to minority interests before giving 25 effect to income tax benefit, discontinued operations, extraordinary item and cumulative effect of accounting change decreased $551,000 or 12%; this decrease is primarily attributable to the increase in our ownership of the Operating Partnership. Our net income available to Common Shareholders decreased $201,000 or 3% reflecting the factors discussed above, combined with the net effect of the following: - $2.6 million increase in Preferred Share dividends resulting from our issuance of three new series of preferred shares in 2001; - $174,000 decrease in expense due to the cumulative effect of an accounting change from our adoption of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" in the prior year; and - $82,000 increase in income associated with discontinued operations. LIQUIDITY AND CAPITAL RESOURCES Cash provided from operations is our primary source of liquidity to fund dividends and distributions, pay debt service and fund working capital requirements. We expect to continue to use cash provided by operations to meet our short-term capital needs, including all property expenses, general and administrative expenses, debt service, dividend and distribution requirements and recurring capital improvements and leasing commissions. We do not anticipate borrowing to meet these requirements. Factors that could negatively affect our ability to generate cash from operations in the future are discussed in our 2001 Annual Report on Form 10-K. We historically have financed our long-term capital needs, including property acquisitions and construction activity, through a combination of the following: - cash from operations; - borrowings from our secured revolving credit facility with Bankers Trust Company (the "Revolving Credit Facility"); - borrowings from new loans; - additional equity issuances of Common Shares, Preferred Shares, Common Units and/or Preferred Units; - contributions from outside investors into real estate joint ventures; and - proceeds from sales of properties. We often use our Revolving Credit Facility initially to finance much of our investing and financing activities. We then pay down our Revolving Credit Facility using proceeds from long-term borrowings collateralized by our properties as attractive financing conditions arise and equity issuances as attractive equity market conditions arise. Amounts available under the Revolving Credit Facility are generally computed based on 65% of the appraised value of properties pledged as collateral. As of August 8, 2002, the maximum amount available under our Revolving Credit Facility is $150.0 million, of which $33.0 million is unused. We own real estate through joint ventures when suitable equity partners are available at attractive terms. We use joint ventures primarily for properties undergoing construction or development and, upon completion of construction and development activities, the properties are acquired by us or sold to third parties. The primary business purpose behind the use of such joint ventures is to leverage our equity funding of such projects and reduce the risk of construction and development activities; another purpose in a number of these joint ventures is to make use of the expertise of our joint venture partner in managing the entity's activities. In some of these joint ventures, the joint venture partner acts as project manager during construction and development activities and property manager once the building goes operational; in other cases, we serve the role of project manager and property manager. All of our joint ventures have a two-member management committee responsible for making all major decisions and we control one of the two positions in all of these joint ventures. The joint venture partners in four of our five real estate joint ventures in place at June 30, 2002 are controlled by an entity that owns, manages, leases and develops properties primarily in the Baltimore/Washington Corridor and acts as 26 project manager for these joint ventures. The joint venture partner in our other real estate joint venture is controlled by an individual that invests nationally in a number of real estate entities; we act as project manager for this joint venture. See Note 5 to our consolidated financial statements for additional information pertaining to our real estate joint venture investments. Factors that could negatively affect our ability to finance our long-term capital needs in the future are discussed in our 2001 Annual Report on Form 10-K.

(1) Our 2002 loan maturities include a $10.6 million construction loan maturity in December that may be extended for a one-year period, subject to certain conditions; as of June 30, 2002, we were in compliance with the necessary conditions for us to extend this loan. Our 2002 loan maturities also include a $25.0 million loan maturity in September; we expect to complete an agreement with the lender to extend this loan for a one-year period. We expect to make payments on our other 2002 loan maturities using cash generated from operations. (2) We expect to pay costs on construction projects underway primarily using existing construction loan facilities in place (see discussion below). (3) We expect to pay these items using cash generated from operations. (4) We do not expect to have to fulfill our obligations as guarantor of joint venture loans. In addition to the contractual obligations set forth above, we also had the following commitments at June 30, 2002: - We may need to make our share of additional investments in our real estate joint ventures (generally based on our percentage ownership) in the event that additional funds are needed. In the event that the other members of these joint ventures do not pay their share of investments when additional funds are needed, we may then need to make even larger investments in these joint ventures. - In four of our joint ventures, we would be obligated to acquire the membership interests of those joint ventures not owned by us (20% in the case of three and 50% in the case of one) in the event that all of the following were to occur: (1) an 18-month period passes from the date that 85% of the square feet in the joint ventures' respective buildings become occupied (the "18-month period"); (2) at the end of the 18-month period, the joint ventures' respective buildings are 90% leased and occupied by tenants who are not in default under their leases; and (3) six months passes from the end of the 18-month period and either the buildings are not sold or we have not acquired the other members' interests. The amount we would need to pay for those membership interests is computed based on the amount that the owners of those interests would receive under the joint venture agreements in the event that the buildings were sold for a capitalized fair value (as defined in the agreements) on a defined date. At June 30, 2002, none of the buildings in these joint ventures have occupancy equal to or exceeding 85%. - At June 30, 2002, we are under contract to sell our property located at 8815 Centre Park Drive in Columbia, Maryland for $7.2 million. We completed the sale of this property on July 18, 2002. We had no other material contractual obligations as of June 30, 2002 besides the items discussed above and tenant improvements and leasing costs in the ordinary course of business. 28 INVESTING AND FINANCING ACTIVITIES FOR THE SIX MONTHS ENDED JUNE 30, 2002 During the six months ended June 30, 2002, we acquired six office buildings totaling 312,431 square feet for $32.7 million and a parcel of land for $3.8 million. These acquisitions were financed by: - - using $31.0 million in borrowings on our Revolving Credit Facility; - - using $3.0 million from a new mortgage loan payable; and - - using cash reserves for the balance. During the six months ended June 30, 2002, we completed the construction of three office buildings totaling 279,167 square feet. Costs incurred on these buildings through June 30, 2002 total $45.7 million. These costs were funded in part using $27.1 million in proceeds from two construction loan facilities that were repaid in 2002 using proceeds from a new loan. We also used $9.6 million in contributions from joint venture partners prior to our acquisition of the joint venture partners' interests in 2002; the acquisitions of the joint venture partners' interests were funded using proceeds from a new loan and borrowings on our Revolving Credit Facility. The balance of the costs was funded primarily using proceeds from our Revolving Credit Facility and cash from operations. As of June 30, 2002 (excluding the construction activities of two joint ventures), we had construction activities underway on three buildings totaling 255,019 square feet that were 59.6% operational and 60.2% pre-leased. Estimated costs upon completion for these projects total approximately $43.8 million. Costs incurred on these buildings through June 30, 2002 total $38.6 million. We have construction loan facilities in place totaling $26.2 million to finance the construction of two of these projects; borrowings under these facilities total $18.6 million at June 30, 2002. We also used borrowings from our Revolving Credit Facility and proceeds from debt refinancings to fund these activities. During the six months ended June 30, 2002, we acquired the remaining 20% interest not previously owned by us in one of our unconsolidated real estate joint ventures, MOR Montpelier LLC, and simultaneously sold the 43,785 square foot building owned by that entity for net proceeds of $1.1 million. We also acquired a 50% interest in MOR Montpelier 3 LLC, an entity developing a parcel of land located in Columbia, Maryland. Our investments in unconsolidated real estate joint ventures increased by $461,000 during the six months ended June 30, 2002 due primarily to the net effect of these transactions and our funding of initial development activities in our NBP 140, LLC joint venture; we do not expect the need to fund more than $2.0 million in additional development costs of NBP 140, LLC. During the six months ended June 30, 2002, we sold a land parcel for $1.3 million, providing a $1.0 million mortgage loan to the purchaser. The net proceeds from this sale after transaction costs and the loan provided by us to the purchaser totaled $250,000, all of which was applied to our cash reserves. During the six months ended June 30, 2002, we borrowed $72.2 million under mortgages and other loans payable other than our Revolving Credit Facility, the proceeds of which were used as follows: - - $52.1 million to repay other loans; - - $11.0 million to pay down our Revolving Credit Facility; - - $7.7 million to finance acquisitions; - - $1.3 million to finance construction activities; and - - the balance to fund cash reserves. On March 5, 2002, we participated in an offering of 10,961,000 Common Shares to the public at a price of $12.04 per share; Constellation was the owner of 8,876,172 of these shares and 2,084,828 of these shares were newly issued by us. With the completion of this transaction, Constellation, which had been our largest shareholder, is no longer a shareholder. We contributed the net proceeds from the sale of the newly-issued shares to our Operating Partnership in exchange for 2,084,828 Common Units. The Operating Partnership used most of the proceeds to pay down our Revolving Credit Facility. 29 INVESTING AND FINANCING ACTIVITY SUBSEQUENT TO THE SIX MONTHS ENDED JUNE 30, 2002 On July 18, 2002, we sold our property located at 8815 Centre Park Drive in Columbia, Maryland for a sales price of $7.2 million, of which $3.6 million was applied to the purchase of the buildings described below and the balance used to pay down the Revolving Credit Facility. Between July 18 and August 1, 2002, we acquired for a purchase price of $30.9 million an office building totaling 236,441 square feet and a parcel of land. These acquisitions were financed using $22.0 million from a new mortgage loan, $3.6 million in proceeds from the sale of our property on July 18, 2002 and the balance from our Revolving Credit Facility. In July 2002, we became committed to acquire for a purchase price of $47.0 million two office buildings totaling 290,245 square feet and a parcel of land. We expect to complete this acquisition in August 2002 using $16.0 million from a new mortgage loan, $16.0 million from an assumed mortgage loan and proceeds from our Revolving Credit Facility for the balance. In July 2002, we obtained a $12.0 million mortgage loan payable with SunTrust Bank. The loan has a one-year term with two options to renew for an additional six months and carries interest at LIBOR plus 1.5%. The proceeds from this loan were used to pay down our Revolving Credit Facility. We also obtained a $27.8 million mortgage loan payable with State Farm Life Insurance Company. The loan has a ten-year term and carries interest at 6.51%. The proceeds from this loan were used to pay off a $15.8 million mortgage loan payable and to pay down our Revolving Credit Facility. STATEMENT OF CASH FLOWS We generated net cash flow from operating activities of $29.2 million for the six months ended June 30, 2002, an increase of $6.2 million from the six months ended June 30, 2001. Our increase in cash flow from operating activities is due primarily to income generated from our newly-acquired and newly-constructed properties. Our net cash flow used in investing activities for the six months ended June 30, 2002 increased $8.3 million from the six months ended June 30, 2001 due primarily to additional cash outlays of $23.8 million in connection with purchases of and additions to commercial real estate properties, offset by a $7.0 million decrease in investments and advances to unconsolidated real estate joint ventures and an $8.8 million decrease in advances to certain real estate joint ventures. Our increase in net cash flow provided by financing activities for the six months ended June 30, 2002 of $1.8 million from the six months ended June 30, 2001 includes an $85.5 million decrease in repayments of mortgage and other loans payable, offset by a $54.0 million decrease in proceeds from mortgage and other loans payable, a $14.3 million decrease in proceeds from the issuance of equity instruments and a $12.3 million decrease in cash flow associated with other liabilities. FUNDS FROM OPERATIONS We consider Funds from Operations ("FFO") to be meaningful to investors as a measure of the financial performance of an equity REIT when considered with the financial data presented under generally accepted accounting principles ("GAAP"). Under the National Association of Real Estate Investment Trusts' ("NAREIT") definition, FFO means net income (loss) computed using GAAP, excluding gains (or losses) from debt restructuring and sales of property, plus real estate-related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures, although we have included gains from the sales of properties to the extent such gains related to development services provided. FFO assuming conversion of share options, Preferred Units and Preferred Shares adjusts FFO assuming conversion of securities that are convertible into our Common Shares when such conversion does not increase our diluted FFO per share in a given period. The FFO we present may not be comparable to the FFO of other REITs since they may interpret the current NAREIT definition of FFO differently or they may not use the current NAREIT definition of FFO. FFO is not the same as cash generated from operating activities or net income determined in accordance with GAAP. FFO is not necessarily an indication of our cash flow available to fund cash needs. Additionally, it should not be used as an alternative to net income when evaluating our financial performance or to cash flow from operating, investing and financing activities when evaluating our liquidity or ability to make cash distributions or pay debt service. Our FFO for the three and six months ended June 30, 2002 and 2001 are summarized in the following table: 30

(1) A portion of the gain from the sales of real estate that is attributable to development services performed on the properties is included in FFO. INFLATION We have not been significantly impacted by inflation during the periods presented in this report due mostly to the relatively low inflation rates in our markets. Most of our tenants are obligated to pay their share of a building's operating expenses to the extent such expenses exceed amounts established in their leases, based on historical expense levels. In addition, some of our tenants are obligated to pay their share of all of a building's operating expenses. These arrangements reduce our exposure to increases in such costs resulting from inflation. 31 ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to certain market risks, the most predominant of which is change in interest rates. Increases in interest rates can result in increased interest expense under our Revolving Credit Facility and our other mortgage loans payable carrying variable interest rate terms. Increases in interest rates can also result in increased interest expense when our loans payable carrying fixed interest rate terms mature and need to be refinanced. Our debt strategy favors long-term, fixed-rate, secured debt over variable-rate debt to minimize the risk of short-term increases in interest rates. As of June 30, 2002, 61.9% of our mortgage and other loans payable balance carried fixed interest rates. We also use interest rate swap and interest rate cap agreements to reduce the impact of interest rate changes. The following table sets forth our long-term debt obligations, principal cash flows by scheduled maturity and weighted average interest rates at June 30, 2002 (dollars in thousands):

For the Periods Ended December 31, ------------------------------------------------------------------------------------------ 2002(1) 2003(2) 2004(3) 2005 2006 Thereafter Total --------- --------- ---------- --------- --------- ---------- ---------- Long term debt: Fixed rate $ 3,266 $ 7,081 $ 33,163 $ 23,905 $ 67,475 $ 257,016 $ 391,906 Average interest rate 7.04% 6.86% 6.89% 6.88% 6.75% 6.90% 6.88% Variable rate $ 35,778 $ 80,014 $ 125,800 $ -- $ -- $ -- $ 241,592 Average interest rate 3.59% 3.88% 3.62% -- -- -- 3.75%

(1) Includes a $10.6 million maturity in December that may each be extended for a one-year period, subject to certain conditions. (2) Includes a $10.9 million maturity in April and a $36.0 million maturity in November, each of which may be extended for a one-year period, subject to certain conditions. (3) Includes a $125.8 million maturity in March and a $25.8 million maturity in August, each of which may be extended for a one-year period, subject to certain conditions. The fair market value of our mortgage and other loans payable was $647.1 million at June 30, 2002. The following table sets forth information pertaining to our one derivative contract in place as of June 30, 2002:

Notional Fair Value Nature of Amount One-Month Effective Expiration on June 30, 2002 Derivative (in millions) LIBOR base Date Date (in thousands) - ------------------ ------------- ---------- ----------- ---------- ---------------- Interest rate swap $ 100.0 5.76% 1/2/01 1/2/03 $ (1,970)

Based on our variable-rate debt balances, our interest expense would have increased by $684,000 during the six months ended June 30, 2002 if interest rates were 1% higher. 32 PART II ITEM 1.
