Item 1. Changes in Control of Registrant
 
    On October 14, 1997, Royale Investments, Inc. (the "Company"), H/SIC
Corporation, a Delaware corporation ("H/SIC"), Strategic Facility Investors,
Inc., a Delaware corporation ("Strategic"), the sole general partner of Blue
Bell Investment Company, L.P., a Delaware limited partnership ("Blue Bell,
L.P."), South Brunswick Investment Company, LLC, a New Jersey limited liability
company ("SBIC"), a general partner of South Brunswick Investors, L.P., a
Delaware limited partnership ("South Brunswick, L.P."), ComCourt Investment
Corporation, a Pennsylvania corporation ("ComCourt Corporation"), the sole
general partner of ComCourt Investors, L.P., a Delaware limited partnership
("ComCourt, L.P."), and Gateway Shannon Development Corporation, a Pennsylvania
corporation ("Gateway"), the sole general partner of 6385 Flank Drive, L.P., a
Pennsylvania limited partnership ("Flank, L.P."), completed a number of
transactions (collectively, the "Shidler Transactions") pursuant to the
Formation/Contribution Agreement dated September 7, 1997, as amended by the
Amendment thereto dated as of October 13, 1997 (collectively, the "Formation
Agreement"). H/SIC, Strategic and ComCourt Corporation are each 50% owned by Jay
H. Shidler ("Shidler") and Clay W. Hamlin, III ("Hamlin"). Gateway is owned by
Mr. Hamlin. Although the Shidler Transactions involved a number of properties
and partnerships and were effected by a series of intermediate steps, the
Shidler Transactions were negotiated and effected as a unitary transaction in
which one part would not have been done without the other and, in effect,
constituted as described below the acquisition ("Acquisition") by the Company of
an interest in a Delaware limited partnership, FCO, L.P. ("FCO"), formed to
acquire a portfolio of ten properties ("Shidler Acquisition Properties")
representing the Mid-Atlantic suburban office operations of The Shidler Group, a
national real estate investment firm.
 
    Pursuant to the Shidler Transactions, the Company became the sole general 
partner of FCO, and FCO acquired all of the limited partnership interests in 
Blue Bell, L.P., South Brunswick, L.P., ComCourt, L.P. and Flank, L.P. 
(collectively the "Properties Partnerships") except for an 11% limited 
partnership interest in Blue Bell, L.P. retained by Shidler Equities, L.P., a 
limited partnership in effect controlled by Mr. Shidler and his wife, 
Wallette Shidler ("Equities L.P."), and 11% limited partnership interests in 
each of ComCourt, L.P. and Flank, L.P. retained by Mr. Hamlin (collectively 
the "Retained Interests"). Immediately prior to the acquisition by FCO of 
such limited partnership interests, the general partnership interests in the 
respective Properties Partnerships held 
 
                                       2


by Strategic, SBIC, ComCourt Corporation and Gateway were converted into limited
partnership interests, and FCO Holdings, Inc. ("Holdings"), a wholly-owned
Delaware subsidiary of the Company, was admitted as the sole general partner of
each of the Properties Partnerships, holding a .1% interest in each of them. The
Company has a 20.6946% interest (before giving effect to the contribution of
Retained Interests) in FCO which it acquired as a result of the contribution by
the Company to FCO of certain limited partnership interests in various of the
Properties Partnerships which had been assigned directly to the Company in
exchange for 600,000 shares of common stock ("Common Shares") of the Company. In
addition, until December 31, 2000, a portion of the Profits (as defined in the
FCO Partnership Agreement) for each fiscal year is to be allocated 19.8% to the
Company as the general partner and 80.2% to all partners (including the Company
as the general partner but not the preferred limited partners holding Preferred
Units (as defined below)).
 
    The Retained Interests are required to be contributed by Equities L.P. and
Hamlin to FCO in November 2000 in consideration for the issuance to them of
limited partnership interests in the form of an aggregate of 282,508 Common
Units (as defined below) and 186,455 Preferred Units.
 
    FCO was formed as a Delaware limited partnership by the Company on 
October 9, 1997 for the purpose of effecting the Shidler Transactions. On 
October 14, 1997 the Company, as the sole general partner of FCO, and the 
limited partners and preferred limited partners named therein entered into a 
limited partnership agreement dated that day (the "FCO Partnership 
Agreement").
 
    Each of the Properties Partnerships holds one or more suburban office
buildings located in South Brunswick, New Jersey, Blue Bell, Pennsylvania and
Harrisburg, Pennsylvania. The Shidler Acquisition Properties comprise ten
buildings aggregating approximately 1.5 million square feet and in the aggregate
are currently 99.8% leased to major corporate tenants, including Unisys
Corporation, IBM Corporation, Teleport Communications Group, Merck, Hershey
Foods, Pitney-Bowes, Ernst & Young and McGraw-Hill. These leases expire in
various years, commencing in September 1999 and running to June 2009. Six of
these buildings are occupied by single tenants. The Company, through FCO and
Holdings, intends to continue the business of the Properties Partnerships of
owning and leasing commercial office buildings.

                                       3


    Immediately prior to the Acquisition, each of the Properties Partnerships
jointly and severally entered into a $100 million principal amount mortgage
financing with Bankers Trust Company pursuant to a Senior Secured Credit
Agreement dated as of October 14, 1997 ("Credit Facility"). Approximately $96.1
million of the proceeds of the Credit Facility was used by entities other than
the Company and FCO to refinance indebtedness of or secured by the assets of the
Properties Partnerships and to pay various costs in connection with the Shidler
Transactions. Approximately $3.9 million of the proceeds of the Credit Facility
were contributed to FCO in connection with the Shidler Transactions. FCO used
approximately $2.9 million of these funds to pay various costs associated with
the Shidler Transactions and retained approximately $1.0 million for working
capital needs. FCO is a joint and several obligor in respect of the Credit
Facility. The Company and Holdings are not obligors with respect to the Credit
Facility, but have pledged certain assets described below to secure repayment of
the Credit Facility. The initial term of the Credit Facility is three years with
the right given to the obligors to extend it, subject to the satisfaction of
conditions precedent thereto, for two successive one year extensions.
Substantially all of the assets of the Properties Partnerships and FCO's and
Holdings' interests in the Properties Partnerships and the Company's interests
in Holdings and FCO have been pledged or mortgaged to secure the Properties
Partnerships' and FCO's joint and several obligations in respect of the Credit
Facility.
 
    For the purposes of the Acquisition, the Properties Partnerships were 
treated as having a value of $170 million (before giving effect to the 
indebtedness represented by the Credit Facility). For purposes of determining 
the consideration to be given in respect of the acquisition by FCO of limited 
partnership interests in the Properties Partnerships, limited partner 
interests were issued (and will be issued in November 2000 for Retained 
Interests) at the rate of one unit for every $5.50 in exchange value (the 
"Common Units") and preferred partnership units were issued (and will be 
issued in November 2000 for Retained Interests) at a rate of one unit for 
every $25.00 in exchange value (the "Preferred Units").
 
    The aggregate consideration issued in the Shidler Transactions by the
Company and FCO on October 14, 1997 to the former general and limited partners
of the Properties Partnerships consisted of (x) 600,000 Common Shares (issued at
a price of $5.50 per share); (y) an aggregate of 2,899,310 Common Units
(including 600,000 Common Units issued to the Company in consideration for
limited partnership interests in the Properties 

                                       4


Partnerships acquired by the Company for 600,000 Common Shares and 
subsequently contributed by the Company to FCO); and (z) 1,913,545 Preferred 
Units in FCO.
 
    Prior to the execution and delivery of the Formation Agreement, there was no
material relationship between the general and limited partners of the Properties
Partnerships and the Company or any of its affiliates.
 
    The nature and amount of consideration given and received by the Company in
the Shidler Transactions was based on its judgment as to the fair market value
of the Shidler Acquisition Properties and the Common Shares at the time the
Formation Agreement was negotiated.
 
    Preferred Units of FCO may be converted on or after October 1, 1999 into
Common Units on the basis of 3.5714 Common Units for each Preferred Unit being
converted plus an amount in cash equal to the accrued Priority Return Amount (as
defined in the FCO Partnership Agreement) in respect of such Preferred Units.
 
    Subject to compliance with the FCO Partnership Agreement, beginning on
September 1, 1998, each limited partner of FCO has the right to require FCO to
redeem all or a portion of the Common Units held by such limited partner. FCO
(or the Company as its general partner) has the right, in its sole discretion,
to deliver to such redeeming limited partner either one Common Share (subject to
anti-dilution adjustment) or a cash payment equal to the then fair market value
of such Common Share (so adjusted) (based on the formula for determining such
value set forth in the FCO Partnership Agreement). Such rights of redemption and
conversion are immediately exercisable upon the happening of a Special Event (as
defined in the FCO Partnership Agreement). The redemption of Common Units for
Common Shares will have the effect of increasing the Company's interest in FCO.
 
    The right to receive Common Shares upon exercise of such right of redemption
is subject to compliance by the Company with a number of significant conditions
precedent including compliance with the Company's charter, all requirements
under the Internal Revenue Code of 1986, as amended, applicable to real estate
investment trusts, the Minnesota Business Corporation Act or any other law then
in effect and any applicable rule or policy of any stock exchange or
self-regulatory organization.

    Pursuant to the Shidler Transactions, Messrs. Shidler and Hamlin each
acquired 300,000 Common Shares in exchange for partnership interests in various
of the Properties Partnerships. The right to acquire 147,818 of these Common
Shares (73,909 by each of Messrs. Shidler and Hamlin) was acquired by Mr.
Shidler and Mr. Hamlin for cash payments aggregating $813,000 to the persons who
contributed certain of these partnership interests to the Company. The Common
Shares issued to Mr. Shidler and Mr. Hamlin represent, in the aggregate,
approximately 26% of the outstanding Common Shares immediately following the
Shidler Transactions. The Properties Partnerships had prior to the Shidler
Transactions in effect been controlled by Mr. Shidler and Mr. Hamlin.
 
    Concurrently with the closing of the Shidler Transactions and pursuant to
the Formation Agreement, the Company ac-

                                       7


quired for 273,729 Common Shares all of the assets of Crown Advisors, Inc. 
("Crown") (including 27,646 Common Shares held by Crown and valued for this 
purpose at $5.50 per share). The Common Shares held by Crown were then 
retired. Crown had been the advisor to the Company pursuant to a management 
contract. All of the outstanding capital stock of Crown was owned by Vernon 
R. Beck and John Parsinen, then directors and Chairman of the Board and Chief 
Executive Officer and Secretary, respectively, of the Company. The management
contract between Crown and the Company was terminated and the Company entered
into a new management agreement with Glacier Realty, LLC ("Glacier"), a
Minnesota limited liability company all of the interests in which are owned by
Vernon R. Beck and John Parsinen. Under this management agreement, Glacier will
be responsible for the management of the retail properties of the Company.
 
     Upon completion of the Shidler Transactions, Mr. Hamlin, Mr. Shidler,
William H. Walton and Kenneth S. Sweet, Jr., nominees of the persons who
previously directly or indirectly held the general and limited partnership
interests in the Properties Partnerships, were elected directors of the Company
and John Parsinen, Orvin J. Hall and Kurt Schoenrock resigned from the Board of
Directors of the Company. Messrs. Vernon R. Beck, Allen C. Gehrke and Kenneth D.
Wethe continued as directors. The Board of Directors of the Company consists of
seven directors. All directors are elected to serve until they die or retire or
until the next annual meeting of the shareholders of the Company and their
successors are elected and qualified. Mr. Shidler has been elected Chairman of
the Board of Directors of the Company as provided by the Formation Agreement.

          UNAUDITED PRO FORMA CONDENSED CONSOLIDATING FINANCIAL INFORMATION
                                           
The following financial information sets forth the unaudited pro forma condensed
consolidating balance sheet of Royale Investments, Inc. ("Company") as of
September 30, 1997, and the unaudited pro forma condensed consolidating
statements of operations for the year ended December 31, 1996 and the nine month
period ended September 30, 1997.

The unaudited pro forma condensed consolidating financial information is
presented as if the following transactions ("Shidler Transactions") had been
consummated on September 30, 1997 for balance sheet purposes, and as of January
1, 1996 for purposes of the statements of operations.  

- -    The Company acquired partnership interests in a portfolio of 10 
     properties, ("Shidler Acquisition Properties"), representing the 
     Mid-Atlantic suburban office operations of The Shidler Group, a national 
     real estate investment firm. 
    
- -    In the Shidler Transactions, the Company became the sole general 
     partner of and obtained an 18.86% interest in FCO, L.P. ("FCO"), an 
     operating partnership formed to acquire and hold the Shidler Acquisition 
     Properties.  The Company's 18.86% interest is calculated after giving 
     effect to the required contribution to FCO of 11% retained limited 
     partner ownership interests in 7 of the 10 Shidler Acquisition 
     Properties by affiliates of the Shidler Group ("Retained Interests") in 
     exchange for Common Units (as defined below) in November 2000.
    
- -    In connection with the Shidler Transactions, the Company issued 
     600,000 shares of $0.01 par value common stock ("Common Shares") and FCO 
     issued (or committed to be issued) 3,181,818 common partnership units 
     ("Common Units") and 2.1 million preferred partnership units ("Preferred 
     Units").  See Note 1.
    
- -    Immediately prior to the acquisition by the Company, the long term 
     debt on the Shidler Acquisition Properties was refinanced with a $100.0 
     million mortgage loan.
    
- -    Simultaneous with the Shidler Transactions, the Company issued 
     273,729 Common Shares in exchange for the assets of Crown Advisors, Inc. 
     ("Crown"), an affiliate of the Company, previously acting as external 
     advisor to the Company and assisting in the management operations.  The 
     contract between Crown and the Company was terminated.  Further, the 
     Company retired 27,646 Common Shares previously held by Crown at the 
     time it was acquired.
    
- -    The Company entered into a property management agreement with 
     Glacier Realty, LLC ("Glacier"), all of the interests in which are owned 
     by two current officers of the Company, one of whom is also a current 
     director.  The property management agreement with Glacier provides for 
     Glacier to manage the seven net lease retail assets of the Company for a 
     term of five years with a minimum fee of $250,000 per annum.

2,581,818 Common Units at $5.50 per Common Unit ($14.2 million) for a total

                       REPORT OF INDEPENDENT ACCOUNTANTS



The Partners
The Shidler Acquisition Properties:
 
We have audited the accompanying combined balance sheets of The Shidler
Acquisition Properties (Group), a group of partnerships more fully described in
Note 1, as of December 31, 1995 and 1996 and the related combined statements of
operations, partners' capital and cash flows for each of the years in the
three-year period ended December 31, 1996. These financial statements are the
responsibility of the Group's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the combined financial position of the The Shidler
Acquisition Properties as of December 31, 1995 and 1996 and the combined results
of their operations and their cash flows for each of the years in the three-year
period ended December 31, 1996 in conformity with generally accepted accounting
principles.

eliminated to reflect the combined results.
 
    Interim Financial Reporting:
 
    The combined financial statements as of September 30, 1997, and for the nine
months ended September 30, 1996 and 1997, are unaudited; however, in the opinion
of management, all adjustments (consisting solely of normal recurring
adjustments) necessary for a fair presentation of the combined financial
statements for the interim periods have been included. The results for the
interim periods are not necessarily indicative of the results for the full year.
 
2. Summary of Significant Accounting Policies:
 
    Use of Estimates:
 
    The preparation of the combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities as of
the date of the financial statements and the reported amounts of revenues and
expenses during the reporting periods. Actual results could differ from those
estimates.
 
    Revenue Recognition:
 
    Rental income from tenants is recognized on a straight-line basis regardless
of when payments are due. Deferred rent receivable represents rental income
recognized in excess of contractual payments due.
 
    Rents Received in Advance and Tenant Security Deposits:
 
    Rents received in advance represent the advance payment of contractual rent.
Security deposits are amounts paid by tenants to the Group which are then
refunded to such tenant at the end of the lease term subject to certain
conditions.

2. Summary of Significant Accounting Policies, continued:

    Concentration of Credit:
 
    As of December 31, 1996, the Group's two most significant tenants are Unisys
Corporation and IBM Corporation. The Group's lease with Unisys and IBM
Corporation comprise 67% and 12%, respectively, of the Group's annualized rental
income. These concentrations are mitigated, in part, by unconditional sublease
obligations with other tenants. The ability of these and other tenants of the
Group to make required payments is dependent upon the financial condition of the
tenants.
 
    Investment in Real Estate and Depreciation:
 
    The Group's investments in real estate are recorded at cost. Effective
January 1, 1996, the Group adopted Statement of Financial Accounting Standards
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to be Disposed Of." This statement requires that management of the Group
review long-lived assets for impairment whenever circumstances indicate that the
carrying amount of the asset may not be recoverable. Adoption of this statement
did not affect the Group's financial position or results of operations.
 
    Interest expense, real estate taxes and other directly related expenses
incurred during construction periods are capitalized and depreciated commencing
with the date the asset is placed in service and on the same basis as the
related assets. Depreciation expense is computed using the straight-line method
based on the following useful lives:
 
                                                                  Years
                                                                ---------

   Buildings and building improvements........................   39 to 40
   Tenant improvements and equipment..........................       5-11

     Tenant improvements and leasing commissions are capitalized and amortized
over the terms of each specific lease. Maintenance and repairs are charged to
expense when incurred. Expenditures for property improvements are capitalized.
 
    Cash and Cash Equivalents:
 
    For purposes of the statements of cash flows and balance sheets, cash and
cash equivalents include all cash and liquid investments with an initial
maturity of three months or less. The carrying amount of cash equivalents
approximates fair value.
 
    The Group maintains cash in deposit accounts which, from time to time, may
exceed federally insured limits. The Group has not experienced any losses in
such accounts and believes it is not exposed to any significant credit risk on
cash.

2. Summary of Significant Accounting Policies, continued:

    Restricted Cash and Escrows:
 
    In accordance with the provisions of the mortgage note payable for Blue
Bell, excess funds (as defined) are invested in commercial paper in amounts up
to the extent of the next interest and principal payment. These funds, which are
invested in Grade A Commercial Paper, were $11, $2,649 and $1,597 at December
31, 1995, 1996 and September 30, 1997, respectively. The remaining account
balance relates to insurance and tax escrows.
 
    Income Taxes:
 
    No income taxes are payable by the Group, and none have been provided in the
accompanying combined financial statements. The partners are required to include
their respective shares of partnership profits and losses in their individual
tax returns.
 
    Fair Value of Financial Instruments:
 
    The financial instruments of the Group include short-term investments and
mortgage and construction loans payable. The estimated fair values of these
instruments were not materially different from their carrying values. On October
14, 1997, in connection with the acquisition of the Group by Royale Investments,
Inc., all of the Group's mortgage and construction loans payable at December 31,
1996 and September 30, 1997 (with a weighted average interest rate of
approximately 10.8%) were refinanced with $100,000 of long-term debt at an
interest rate of 7.5%.
 
    Deferred Costs:
 
    Fees and costs associated with lease originations and costs incurred to
obtain long-term financing have been capitalized and are amortized over the
terms of the respective leases or debt. At December 31, 1995, 1996, and
September 30, 1997, deferred costs include the following:
 


                                                                December 31,      September 30,

6. Commitments and Contingencies:
 
    From time to time, the Group is subject to routine litigation incidental to
its business. The Group believes that the results of any pending legal
proceedings will not have a materially adverse effect on the Group's financial
condition or results of operations.
 
7. Subsequent Event:
 
    On October 14, 1997, all of the mortgage notes payable (Note 4) were
refinanced and replaced with a $100,000 mortgage note which bears interest at
7.5%. Thereafter, Royale Investments, Inc. closed on the acquisition of the
Group. Neither transaction had any effect on these financial statements.
