     terms are used in the Comprehensive Environmental Response, Compensation
     and Liability Act of 1986, as amended, the Resource Conservation and
     Recovery Act of 1976, as amended, or in any other applicable federal, state
     or local laws, ordinances, rules or regulations relating to protection of

                                      -18-


     proceeding or action pending or threatened by any person or governmental

          (n) Personal Property. Attached hereto as Exhibit "H/SIC Personal
     Property" and complete inventory of all personal property ('H/SIC Personal
     Property"), if any, used in the management, maintenance and operation of
     the H/SIC Property (other than trade fixtures or personal property of
     tenants).

          (o) Leasing Commissions. There are, and at Closing shall be, no
     outstanding or contingent leasing commissions or fees payable with respect
     to the H/SIC Property.

          (p) Partnership Liabilities. Except for (i) the obligations and
     liabilities of the H/SIC Partnership which the UPREIT is taking the H/SIC
     Partnership Interests subject to under Section 7(d) above, and (ii) any
     accrued liabilities and obligations of the H/SIC Partnership which are
     being adjusted at Closing pursuant to Section 22(d) of this Agreement, the
     H/SIC Partnership shall not have any liabilities or obligations, either
     accrued, absolute or contingent or otherwise, which will not be paid or
     discharged on or before the Closing Date. In addition, except for the
     claims and liabilities described in the preceding sentence or otherwise
     described or disclosed in this Agreement (including the Exhibits hereto),
     the H/SIC Partnership has not received notice of any, and to the knowledge
     of the H/SIC General Partner, there is, as of the date of execution of this
     Agreement, no basis for any, claim against (or liability of) the
     Partnership arising from the business done, transactions entered into or
     other events occurring prior to the Closing Date which will not be
     discharged by the H/SIC Partnership before the Closing Date.

          (q) Partnership for Tax Purposes. The H/SIC Partnership is, and at all
     times has been, properly treated as a partnership for federal income tax
     purposes, and not as an "association" or "publicly traded partnership"
     taxable as a corporation.



                                      -19-


          (r) Taxes. Each of the H/SIC Partnership and any predecessor of the
     H/SIC Partnership has timely filed with the appropriate taxing authorities
     all returns (including without limitation information returns and other
     material information) in respect of Federal, State and local taxes
     (collectively "Taxes") required to be filed through the date hereof and
     will timely file any such returns required to be filed on or prior to the
     Closing Date. The returns and other information filed (or to be filed) are
     complete and accurate in all material respects. All Taxes of the H/SIC
     Partnership in respect of periods beginning before the Closing Date have
     been timely paid, or will be timely paid prior to the Closing Date, and the
     H/SIC Partnership has no material liability for Taxes in excess of the
     amounts so paid. All Taxes that the H/SIC Partnership has been required to
     collect or withhold have been duly collected or withheld and, to the extent
     required when due, have been or will be (prior to Closing Date) duly paid
     to the proper taxing authority. No audits of any of the H/SIC Partnership's
     federal, state or local returns for Taxes by the relevant taxing
     authorities have occurred, and no material deficiencies for Taxes of the
     H/SIC Partnership have been claimed, proposed or assessed by any taxing or
     other governmental authority against the H/SIC Partnership. There are no
     pending or, to the best of knowledge of the H/SIC General Partner,
     threatened audits, investigations or claims for or relating to any material
     additional liability to the H/SIC Partnership in respect of Taxes, and
     there are no matters under discussion with any governmental authorities
     with respect to Taxes that in reasonable judgment of the H/SIC General
     Partner or its counsel, is likely to result in a material additional
     liability for Taxes. To the knowledge of the H/SIC General Partner there
     are no liens for Taxes (other than for current taxes not yet due and
     payable) on any of the assets of the H/SIC Partnership. No Contributor is a
     person other than a United States person within the meaning of the Code.
     The transaction contemplated herein is not subject to the tax withholding
     provisions of Section 3406 of the Code, or Subchapter A of Chapter 3 of the
     Code or of any other provision of law.

          (s) Disclosure. No representation or warranty made by the H/SIC
     General Partners in this Agreement or in any documents delivered or to be
     delivered by the H/SIC General Partners contains any untrue statement of a
     material fact, or omits to state a material fact necessary in order to make
     the statements contained therein not misleading,



                                      -20-


     or necessary in order to provide adequate information as to the H/SIC
     Partnerships and the H/SIC Properties and their management, operation,
     maintenance and repair. All items delivered or to be delivered by the H/SIC
     General Partners pursuant to the terms of this Agreement are true, correct
     and complete in all material respects, and fairly present the information
     set forth therein in a manner that is not misleading.

     11. Obligations of General Partners Pending Closing. From and after the
date of this Agreement through the Closing Date, each H/SIC General Partner,

     normal operation thereof, including the purchase and replacement of
     fixtures and equipment, and the continuation of the normal practice with
     respect to maintenance and repairs so that the H/SIC Property will, except
     for normal wear and tear and damage by fire or other casualty (subject to
     Section 16), be in substantially the same condition on the Closing Date as
     on the date hereof.

          (b) Compliance with Governmental Requirements. The H/SIC General
     Partner shall use its commercially reasonable efforts to cause the Property

          (c) Changes in Representations. The H/SIC General Partner shall notify
     Royale promptly, and Royale shall notify the H/SIC General Partner
     promptly, if either becomes aware of any occurrence prior to the Closing
     Date which would make any of its representations, warranties or covenants
     contained herein not true in any material respect.

          (d) Obligations as to H/SIC Leases. The H/SIC General Partner shall
     not, without Royale's prior written consent (which consent shall not be
     unreasonably withheld conditioned or delayed), amend, modify, renew or
     extend any H/SIC Lease in any material respect unless required bylaw, or
     enter into new leases or approve any assignment



                                      -21-

     the H/SIC Properties Indebtedness and shall keep, and cause the H/SIC
     Partnership to keep, the H/SIC Properties Indebtedness free from default.

          (f) No Other Indebtedness. Subject to the H/SIC Properties
     Indebtedness, the H/SIC General Partner shall not incur any indebtedness,
     other than current accounts payable in the day-to-day operation of the
     H/SIC Properties.

          (g) No Solicitation. The H/SIC General Partner will not solicit or
     undertake any recapitalization, business combination or other transaction,
     or engage in any discussions or negotiations with respect thereto, or
     furnish information (other than as required by law or this Agreement) that
     would be inconsistent with the Transactions.

     12. Representations and Warranties of Royale. Royale represents and
warrants to the H/SIC Partners, and covenants with the H/SIC Partners which

hereof, shall be true and correct at Closing and shall survive Closing, as

     Environmental Response, Compensation and Liability Act of 1986, as amended,
     the Resource Conservation and Recovery Act of 1976, as amended, or in any
     other applicable federal, state or local laws, ordinances, rules or
     regulations relating to protection of public health, safety or the
     environment, as such laws may be amended from time to time) at, upon, under
     or within the Land or any contiguous real estate. Except as set forth on
     Exhibit "Royale Environmental Matters" to Royale's knowledge, there is no
     proceeding or action pending or threatened by any person or governmental

     to real estate investment trusts under Section 856 of the Code, and (2) is,




                                      -27-


     and at all times has been, property treated as a real estate investment
     trust under Section 856 of the Code for federal income tax purposes.

          (t) Taxes. Royale and any predecessor of Royale have timely filed with
     the appropriate taxing authorities all returns (including without
     limitation information returns and other material information) in respect
     of Taxes required to be filed through the date hereof and will timely file
     any such returns required to be filed on or prior to the Closing Date. The
     returns and other information filed (or to be filed) are complete and
     accurate in all material respects. All Taxes of Royale in respect of
     periods beginning before the Closing Date have been timely paid, or will be
     timely paid prior to the Closing Date, and the Royale has no material

     has been required to collect or withhold have been duly collected or
     withheld and, to the extent required when due, have been or will be (prior
     to Closing Date) duly paid to the proper taxing authority. No audits of any
     of Royale's federal, state or local returns for Taxes by the relevant
     taxing authorities have occurred, and no material deficiencies for Taxes of
     Royale have been claimed, proposed or assessed by any taxing or other
     governmental authority against Royale. There are no pending or, to the best

     relating to any material additional liability to the Partnership in respect
     of Taxes, and there are no matters under discussion with any governmental
     authorities with respect to Taxes that in reasonable judgment of Royale or
     its counsel, is likely to result in a material additional liability for
     Taxes. To the knowledge of Royale, there are no liens for Taxes (other than
     for current taxes not yet due and payable) on any of the assets of Royale.

          (u) Fairness Opinion. Royale has received a satisfactory "fairness
     opinion" from a reputable Financial advisor selected by Royale's Board of
     Directors with respect to the Transactions.

     not misleading or necessary in order to provide adequate



                                      -28-

without limitation those documents described in Section 20 above to which the
UPREIT (or its designees) or Royale is a party or a required signatory) and take
such other actions required to be taken by Royale at Closing as required under
this Agreement. Without limitation on the foregoing provisions of this Section
21 Royale shall deliver, or cause the delivery of the following documents:

          (a) The original signed Royale Leases and a schedule updating the
     Royale Rent Schedule for the Royale Properties and setting forth all
     arrearages in rents and all prepayments of rents.

          (b) Originally executed Royale Service Contracts and copies of books,
     records, operating reports, files and other materials related to the
     ownership, use and operation of the Royale Properties, to the extent that
     any exist and are in the possession of Royale.

          (c) The Registration Rights Agreement.

          (d) A transfer and assignment agreement by Crown to Royale

     desirable to consummate the Transactions.

          (g) All of the corporate and financial books and records of Royale.

          (h) Such other documents and items (including, without limitation,
     legal opinions customarily in delivered in transactions similar to the
     Transactions) as may be reasonably required under the terms of this
     Agreement or re-



                                      -38-


     lating to the Transactions to reasonably effect the purposes of this
     Agreement or to consummate the Transactions.

     22. Closing Charges; Prorations and Adjustments.

          (a) Royale or H/SIC General Partners on behalf of the H/SIC
     Partnerships and out of the funds of such H/SIC Partnerships), as the case
     may be, shall pay the title examination charges, the title insurance
     premium, survey costs, environmental assessment charges, notary fees and
     other such charges relating to the Royale Properties and the H/SIC
     Properties respectively.

          (b) Although H/SIC General Partners and Royale believe that no real
     estate transfer or recording fees or taxes will be due in connection with
     the contribution of the H/SIC Partnership Interests, if it is finally
     determined that such taxes are due and payable in connection herewith, then
     the H/SIC Partnership for which the transfer of whose H/SIC Partnership
     Interests shall be deemed subject to real estate transfer tax shall pay the
     costs of contesting such taxes and shall pay the full amount of such taxes
     if they are finally determined to be payable. (c) The H/SIC General
     Partners and Royale shall each pay their own due diligence costs and legal,
     brokerage, lenders', investment banking and accounting costs and fees
     related to the Transaction and preparation of this Agreement and all
     documents required to settle the transaction contemplated hereby.

          (d) With respect to each of the H/SIC Properties, as of the 11:59 p.m.
     of the calendar day immediately preceding the Closing Date, there shall be
     apportioned between the H/SIC Partnership owning such H/SIC Property and
     the UPREIT (1) rent under the H/SIC Leases, (2) interest under the H/SIC
     Properties Indebtedness, (3) taxes, insurance and operating expenses of
     such H/SIC Property to the extent borne by the owning H/SIC Partnership,
     and (4) payments with respect to the items listed in the preceding clause
     (3) that are received from tenants to the extent prepaid (including all
     security deposits) or paid in arrears to the owning H/SIC Partnership. All
     management agreements between the H/SIC Partnerships and H/SIC (or any
     affiliate) shall be terminated as of Closing Date, and all fees due under
     such agreements through Closing shall be paid by the H/SIC Partnership. Any
     amount due pursuant to this Section 22(d) shall be paid in cash at the
     Clos-



                                      -39-


     ing. To the extent that the amount of the items to be adjusted are not
     reasonably ascertainable as of the Closing Date, such as tenant chargebacks
     or collections for tenant reimbursements, they shall be adjusted promptly
     after the determination of the amount thereof.

          (e) It is acknowledged and agreed that, on or prior to the Closing,
     the H/SIC General Partners shall cause the H/SIC Partnerships to distribute
     to the H/SIC Partners all cash and assets of the Partnership other than the
     H/SIC Properties.

     23. Partnership Liabilities and Sales of H/SIC Properties.

          (a) Subject to the provisions of Section 23(b) hereof, for a period of
     three (3) years following the Closing Date (the "Non Taxable Disposition
     Period"), Royale and the UPREIT shall use their good faith, reasonable and
     diligent efforts:

               (1) to cause any sale or other voluntary disposition (other than
          through a deed in lieu of foreclosure, a foreclosure action, or an act
          of eminent domain) of the H/SIC Properties to qualify for
          non-recognition of gain under the Code, whether by means of exchanges
          contemplated under Code Sections 351, 354, 355, 368, 721, 1031, 1033,
          or otherwise; provided, however, that the foregoing shall not require
          Royale and the UPREIT, in their sole and absolute discretion, to sell,
          or otherwise dispose of, or prevent Royale and the UPREIT in their
          sole and absolute discretion, from selling or otherwise disposing of
          any of the H/SIC Properties in transactions qualifying for
          non-recognition of loss;

               (2) to avoid a distribution of property that would cause any
          Contributor to recognize income or gain pursuant to the provisions of
          either or both of Code Sections 704(c)(1)(B) and 737; and

               (3) to avoid a termination of the UPREIT pursuant to the
          provisions of Code Section 708(b)(1)(B).

          (b) Notwithstanding the above provisions of Section 23(a), the
     obligation of either or both of Royale and the UPREIT to undertake those
     activities set forth in Section 23(a) hereof shall, in all events, be
     subject to, and oth-



                                      -40-


     erwise interpreted consistent with Royale's fiduciary and statutory
     obligations to all partners (both present and future) in the UPREIT, and to
     its stockholders, both present and future. Notwithstanding the preceding
     sentence, however, the UPREIT and/or Royale shall use every reasonable
     effort (but shall not be required) to engage in a non-taxable disposition
     of an H/SIC Property.

          (c) In addition to the foregoing, and again consistent with and
     subject to Royale's fiduciary, statutory and other obligations to all
     partners (present and future) in the UPREIT, and to all of Royale's
     stockholders, and likewise in all events consistent with and subject to the
     exercise of sound and prudent business judgment in furtherance of the
     interests of all such partners and stockholders, for a period of three (3)
     years after the Closing Date, the UPREIT and Royale shall use their
     respective good faith, reasonable and diligent efforts to deal with the
     aggregate of non-recourse indebtedness ("Aggregate Debt") secured by the
     H/SIC Properties ("Project Specific Mortgages") and excess non-recourse
     indebtedness secured by properties owned by the UPREIT other than the H/SIC
     Properties ("Other Mortgages") in such manner as shall provide Contributors
     that collective allocation of taxable basis derived from either or both of
     Project-Specific and Other Mortgages that is set forth in Exhibit "Schedule
     of H/SIC Debt Allocations." In the event that Royale or the UPREIT
     determines, during the three (3) year period following the Closing, that it
     is necessary or desirable to pay down or retire all or any balance due
     under the Project-Specific Mortgages or Other Mortgages, then the Royale
     and the UPREIT shall be free to do so, subject to the terms of Section
     23(d). In addition, Royale and the UPREIT shall be free from time to time
     and at any time to make scheduled periodic and other payments required
     under the Project Specific Mortgages and Other Mortgages, without notice or
     accountability to any Contributor.

          (d) At Closing, the UPREIT and Royale shall confirm, in writing, to
     the Contributors their respective acknowledgments of, and agreements to
     comply with, the undertakings set forth in Sections 23(a), 23(b), 23(c) and
     23(d).

               (1) In the event, on or before the third anniversary of the
          Closing Date, of (each, a "Tax-Related Event"): (A) a post-Closing
          sale of an H/SIC Property occurs; or (B) an attempt by the UPREIT to
          effect an H/SIC Property transfer as permitted by Section 23(a)



                                      -41-


          above occurs, but the terms of Section 1031 of the Code or the
          regulations promulgated thereunder have changed such that the
          mechanics for implementing a tax-deferred exchange of real estate are
          materially and adversely altered (whether with respect to the timing
          required to identify and close upon an exchange property or otherwise)
          from those mechanics in place as of the date of this Agreement, and,
          in any case, provided that the obligations of the Royale and the
          UPREIT under Section 23 shall not have otherwise terminated by the
          terms of such Section, the H/SIC shall give written notice of such
          Tax-Related Event (a "Tax-Related Notice") to the relevant
          Contributors for the subject H/SIC Property as soon as practicable
          after the occurrence of such event becomes reasonably likely, or, if
          later, on the date on which the UPREIT is, in the reasonable judgment
          of its securities counsel, legally permitted, under applicable federal
          and state securities laws and regulations, and the rules and
          regulations of any securities exchange on which Royale Common Stock
          may be listed, to disseminate such Tax-Related Notice to such
          Contributors.

               (2) Upon their receipt of a Tax-Related Notice, the Contributors
          who were H/SIC Partners in the affected H/SIC Property shall designate
          Jay Shidler, or if he is unable or unwilling to serve, a person
          selected by a majority in H/SIC Partnership Interests of the
          Contributors who were H/SIC Partners in the affected H/SIC Property to
          represent them in connection with the Tax-Related Event that triggers
          the delivery of the applicable Tax-Related Notice (the
          "Spokesperson"). The UPREIT and Royale shall be entitled to rely on
          the first written notice either of them receives that designates a
          Spokesperson with respect to a given Tax-Related Event, and shall be
          under no obligation to deal with any person other than that
          Spokesperson in connection with the subject Tax-Related Event. The
          UPREIT and Royale shall have no obligation to deal with any person or
          entity whatsoever in connection with a Tax-Related Event unless and
          until a Spokesperson is properly designated. The UPREIT and Royale and
          their respective independent accountants, attorneys and other
          representatives and advisors, shall cooperate With the Spokesperson in
          order to consider strategies proposed by or through the Spokesperson
          (it being understood that neither Royale or the UPREIT shall have any
          obligation what-



                                      -42-


          soever to propose any such strategies), on behalf of affected
          Contributors, which strategies are designed or intended to defer or
          mitigate any recognition of gain under the Code by any Contributor or
          any shareholder or partner in any Contributor (any such gain
          recognition being referred to herein as an "Adverse Tax Consequence")
          that may result from a Tax-Related Event, whether such strategies
          involve any or all of the Contributors on a basis independent of
          Royale and the UPREIT, or in conjunction with Royale and the UPREIT.
          The requesting party shall pay its own fees and expenses, and the fees
          and expenses of Royale and the UPREIT, incurred in connection with the
          procedure delineated in this Section 23(d)(2). Under this Section
          23(d), the UPREIT and Royale are only obligated to cooperate with the
          Spokesperson on behalf of any Contributor (or any partner, shareholder
          or member of any Contributor) who may be facing an Adverse Tax
          Consequence, in connection with such Contributor's determination of
          the efficacy of tax-deferral or tax-mitigation alternatives proposed
          by or through the Spokesperson that may involve Royale or the UPREIT.
          In no event shall either Royale or the UPREIT be required to incur any
          expense (other than administrative expenses incurred in complying with
          this Section 23(d)(2)) in connection its cooperation under this
          Section 23(d)(2), nor shall any transaction duly approved by the Board
          of Directors of Royale that results in a Tax-Related Event be required
          to be suspended, postponed, impeded or otherwise adversely affected by
          virtue of any potential Adverse Tax Consequence.

          (e) The provisions of this Section 23 shall not be amended or modified
     without the consent of (1) the H/SIC General Partners and (2) other
     Contributors holding at least seventy percent (70%) of the H/SIC
     Partnership Interests.

     24. Preparation of Documents.

          (a) Royale shall direct its counsel to prepare all documentation
     relating to changes in the directors and senior management of Royale, and
     all Board of Directors resolutions in connection with the Transactions all
     such documents to be subject to the reasonable approval of the H/SIC
     General Partners and their counsel.



                                      -43-

     Interests, all documents pertaining to the H/SIC Properties, documents

          (c) Royale and the H/SIC General Partners shall cooperate in good
     faith and with due diligence to complete in a timely manner all documents
     necessary or desirable to consummate the Transactions.

     any proceedings for the purpose of obtaining such an order, in effect
     preventing consummation of the transactions contemplated by this Agreement
     (other than an order sought by any of the parties), or (B) there shall be
     any action taken, or any statute, rule, regulation or order enacted,
     promulgated, issued or deemed applicable to the transactions contemplated

     of which would be materially and adversely burdensome to any party to this
     Agreement or, in the case of any H/SIC Partnership, to the H/SIC Partners
     of such Partnership (and the party so burdened may elect to terminate), or

          Thousand Dollars ($150,000) as liquidated damages and the sole and
          exclusive remedy of Royale, with no action for damages other than
          $150,000.

          (g) Royale and H/SIC General Partners each agree to execute and
     deliver, or to cause the execution and delivery of, such other documents,
     certificates, agreement and other writings and to take such other actions
     as may be necessary or desirable in order to consummate expeditiously or
     implement the Transactions.

          (h) The parties to this Agreement understand that the structure of the
     Transactions may be subject to change as a result of many factors,
     including, without limitation, federal and state tax considerations,
     securities laws considerations, the requirements of lenders, and corporate
     and partnership law considerations. The parties to this Agreement agree to
     cooperate in good faith to attempt to accommodate any required changes,
     provided that the ultimate benefits to, and burdens of, this Agreement and
     the Transactions to the parties remain as specified in this Agreement,
     notwithstanding any such changes.

          (i) If any provision of this Agreement, or the application thereof, is
     for any reason held to any extent to be invalid or unenforceable, the
     remainder of this Agreement and application of such provision to other
     persons or circumstances will be interpreted so as reasonably to effect the
     intent of the parties hereto. The parties further agree to replace such
     void or unenforceable provision of this Agreement with a valid and
     enforceable provision that will achieve, to the extent possible, the
     economic, business and other purposes of the void or unenforceable
     provisions.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date set forth above.

(1)  Merck subleased 50% of building from Unisys and will be leasing the
     remainder as of January 1, 1999.

(2)  The Ernst & Young lease has not been included in the totals as the lease
     does not commence until November 1, 1997 after the expiration of the
     HealthAmerica lease (8/1/97).

(3)  Teleport has one remaining option for 28,410 s.f. which would bring their
     total square footage to 142,385. We anticipate this option being exercised
     shortly.

(4)  IBM has leased this building along with 431 Ridge Road under a single lease
     until 3/31/02. Teleport has entered into a sub-lease with IBM ending
     3/31/02 and a lease commencing 4/1/02 and ending 12/31/06 with Landlord.

                           "Lease Guarantee Agreement"


     Two separate agreements shall be entered into and funded at Closing between
the UPREIT and (i) the partners of Comcourt Investors, L.P. and (ii) the
partners of South Brunswick Investors, L.P. The substance of the agreements
shall be as follows:

Comcourt Investors, L.P. ("Comcourt")

     1. Comcourt owns an office building of 66,064 rentable square fee, located
at 2601 Market Place, Commerce Park, Harrisburg, PA. The building is 100%
leased; however, on July 31, 1997, the lease for HealthAmerica, which occupies
42,941 sq. ft., is scheduled to expire (the "Vacant Space"). Comcourt has
executed a replacement lease dated May 30, 1997 between Comcourt as Landlord and
Ernst & Young U.S. LLP as Tenant for 17,499 sq. ft. of the Vacant Space,
commencing November 1, 1997 for a term of ten years, as well as a lease dated
August 8, 1997 with Penn State Geisinger System Services as Tenant for 17,665
sq. ft. of the Vacant Space, commencing November 1, 1997 for a term of ten
years, leaving a balance of 7,777 sq. ft. to be leased (the "Unleased Vacant
Space"). The Comcourt partners are negotiating with prospective tenants and
anticipate that leases for the Unleased Vacant Space will be quickly executed.

     2. The partners are transferring their partnership interests to UPREIT at
Closing. As partial consideration for the transfer, the UPREIT has required that
the partners of Comcourt provide the UPREIT an agreement to insure that the
lease income attributable to the Vacant Space is beginning at the date of
Closing attained at the level projected, and, in addition, that the partners of
Comcourt by responsible for all tenant improvement and leasing commissions for
new leases on the Vacant Space, as well as the Ernst and Young and Penn State
Geisinger leases.

     3. The Lease Income From the Vacant Space ("LEASE INCOME") means the
stabilized net rent determined on a GAAP basis.

     4. The Comcourt partners shall fund two cash escrows at Closing. Comcourt
represents that the amounts escrowed are expected to cover all reasonably
anticipated amounts to be needed, based upon the lease terms and conservative
assumptions. The escrow amounts set forth below shall be reduced to the extent
that, prior to Closing, additional leasing of Vacant Space is achieved and/or
tenant improvements and/or leasing commissions are paid by Comcourt.

          (a) The first escrow shall be in cash in the amount of $296,897 (the
     "Comcourt LEASE INCOME Escrow") and shall be used by the UPREIT to the
     extent required on a monthly basis to supplement the income as necessary to
     achieve the LEASE INCOME, beginning at Closing.

               (i) Upon lease up, commencement of occupancy and payment of rent
          for the Vacant Space, the remaining balance of the Comcourt LEASE
          INCOME Escrow shall be released to the Comcourt partners, provided
          that the LEASE INCOME has been achieved. If the LEASE INCOME has not
          been achieved, the amount retained shall be the present value 




          of the amount of the annualized deficit below the LEASE INCOME from
          such time multiplied by the number of years remaining on the lease.

          (b) The second cash escrow shall be created by the Comcourt partners
     in the amount of $945,104 for tenant improvements and leasing commissions
     for the Vacant Space, as well as the full amount of improvements to be
     incurred for the Ernst & Young space and the Penn State Geisinger space per
     the attached schedule (the "Comcourt TI Escrow"). Such amount shall be
     fully funded in cash at Closing. Payments from the Comcourt TI Escrow shall
     be drawn for tenant improvements and leasing commissions for new tenants as
     incurred by the UPREIT. Amounts not expended shall be refunded to the
     Comcourt partners upon lease up of the Vacant Space.

South Brunswick Investors, L.P. ("SBI")


     1. SBI owns an office building of 142,385 rentable square feet, located at
The Princeton Technology Center, 431 Ridge Road, Dayton, NJ. The building has
been undergoing a total renovation and lease up since 1996. 113,975 square feet
have been leased to the tenant, Teleport Communications Group, Inc. ("TCG"), for
a 10 year initial term. TCG has exercised an option to lease the remaining
28,410 sq. ft. (the "Vacant Space") for a ten year term commencing February 1,
1998. The SBI partners have represented to the UPREIT that all capital
improvements respecting the renovation and all tenant improvements for the
113,975 of leased space and the 28,410 option space shall be paid at Closing.

     2. The SBI partners are transferring their partnership interests to the
UPREIT at Closing. As partial consideration for the transfer, the SBI partners
will provide one cash escrow to subsidize the net income attributable to the
Vacant Space from the date of Closing until the commencement of rent and another
cash escrow to fund all tenant improvement and leasing commissions for the new
lease on the Vacant Space.

     3. The Lease Income From the Vacant Space ("LEASE INCOME") means the
stabilized net rent determined on a GAAP basis.

     4. The SBI partners shall fund two cash escrows at Closing. SBI represents
that the amounts escrowed are expected to cover all reasonably anticipated
amounts to be needed, based upon the lease terms. The escrow amounts set forth
below shall be reduced to the extent that, prior to Closing, tenant
improvements, leasing commission or capital improvements are otherwise paid for
which escrowed monies are to be provided hereinafter.

          (a) The first escrow shall be in cash in the amount of $245,563 (the
     "SBI LEASE INCOME Escrow") and shall be used by the UPREIT to the extent
     required on a monthly basis to supplement the income as necessary to
     achieve the LEASE INCOME, beginning at Closing.

               (i) Upon commencement of occupancy and payment of rent for the
          Vacant Space, the remaining balance of the SBI LEASE INCOME Escrow, if
          any, shall be released to the SBI partners.

          (b) The second cash escrow shall be created by the SBI partners at
     Closing in the amount of $3,435,350 for the full amount of improve-





     ments to be incurred for (i) any accrued but unpaid capital improvements
     for the building renovation and unpaid leasing commissions and tenant
     improvements for the 113,975 sq. ft. of leased space as of the date of
     Closing, and (ii) tenant improvements and leasing commissions for the
     Vacant Space, as per the attached schedule (collectively, the "SBI TI
     Escrow"). Such amount shall be fully funded in cash at Closing. Payments
     from the SBI TI Escrow shall be drawn for tenant improvements and leasing
     commissions as incurred by the UPREIT. Amounts not expended shall be
     refunded to the SBI partners upon rent commencement of the Vacant Space.

                        FORMATION/CONTRIBUTION AGREEMENT


     THIS AMENDMENT TO FORMATION CONTRIBUTION AGREEMENT ("Amendment") dated as
of the 13th day of October, 1997 by and among ROYALE INVESTMENTS, INC., a
Minnesota corporation ("Royale"), 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"), 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"),

Pennsylvania corporation ("Gateway"), the sole general partner of 6385 FLANK
DRIVE, L.P., a Pennsylvania limited partnership ("Flank Drive") (collectively,
the "Parties").

                                   BACKGROUND

     The Parties are party to a certain Formation/Contribution Agreement dated
as of September 7, 1997 (the "Formation Agreement"), pursuant to which the
Parties agreed to pursue a series of transactions, the general structure of
which is set forth in the Formation Agreement. Capitalized terms used herein and
not otherwise defined shall have the meanings set forth in the Formation
Agreement.

     Section 26 and Exhibit "Lease Guarantee Agreement" of the Formation
Agreement together outline terms calling for the funding of certain escrows by
the partners of Comcourt and South Brunswick (the "Partners") at Closing. The
Parties have agreed to modify these provisions in a manner intended to
facilitate the overall transaction.

     The Parties also desire to amend the definition of H/SIC Assets, Section
9(d)(9) and Exhibit "UPREIT Agreement Terms" of the Formation Agreement.

     NOW, THEREFORE, for good and valuable consideration, the receipt and
adequacy of which are hereby acknowledged, the parties agree to the following
modifications of the terms of the Formation Agreement:

     1. On the Closing Date, the Partners shall, in lieu of two escrows designed
to subsidize the lease income of Comcourt and South Brunswick (the "Receiving
Partnerships"), fund, or cause to be funded, a single rent escrow account (the
"Rent Escrow"). The Rent Escrow shall be in the amount set forth in the Exhibit
"Lease Income" attached hereto and shall be deposited in an account to be held
and disbursed by Bankers Trust Company pursuant to the provisions of that
certain Credit Agreement to be executed by Royale, FCO, L.P., FCO Holdings,
Inc., Blue Bell, Comcourt, South Brunswick, and Flank Drive in connection with
the H/SIC Properties Indebtedness (the "Credit Agreement"). The Rent Escrow
shall be delivered in its entirety to the Receiving Partnerships pursuant to the
schedule set forth in Exhibit "Lease Income", and the partners shall not be
entitled to the return of any portion of the Rent Escrow.



                                      -2-


     2. On the Closing Date, the Partnerships (and not the Partners) shall, in
lieu of two escrows designed to finance certain tenant improvement obligations
of the Receiving Partnerships, fund a single tenant improvement escrow account
(the "Tenants Costs"). The TI Escrow shall be funded in the amount set forth in
the Exhibit "TI Escrow" attached hereto and shall be deposited in an account to
be held and disbursed by Bankers Trust Company pursuant to the provisions of the
Credit Agreement. The TI Escrow shall be delivered in its entirety to the
Receiving Partnerships pursuant to the schedule set forth in Exhibit "Tenants
Costs", and the Partners shall not be entitled to the return of any portion of
the TI Escrow.

     3. The definition of H/SIC Assets in the Formation Agreement is amended to
read as follows:

          "H/SIC Assets" shall mean H/SIC's furniture, fixtures, equipment and
          proprietary assets.

     4. Section 9(d)(9) of the Formation Agreement is hereby amended to read as
follows:

               "(9) Except as otherwise provided in Section 7(f) and except to
          the extent the UPREIT Agreement may provide for a shorter holding
          period or for shorter holding periods, such Contributor acknowledges
          and agrees that (A) the Common Units to be issued at Closing shall not
          be exchangeable or exchanged for Royale Common Stock for a period of
          thirteen (13) months from and after the date of Closing, and (B)
          Preferred Units to be issued at Closing shall not be exchangeable or
          exchanged for Royale Common Stock for a period of twenty-five (25)
          months from and after the Closing Date. Common Units and Preferred
          Units received by the Retained Partners at the Retained Interests
          Closing shall not be subject to any holding period and the Retained
          Partners shall have the right to exchange immediately for Royale
          Common Stock such Common Units and Preferred Units received at the
          Retained Interests Closing."

     5. The paragraph captioned "Management Expenses" is hereby deleted from
Exhibit "UPREIT Agreement Terms" of the Formation Agreement. The Parties agree
that the Limited Partnership Agreement of FCO, L.P. to be executed at Closing
satisfies the requirements of Exhibit "UPREIT Agreement Terms."

     6. This Amendment may not be amended except by an instrument in writing
signed by the parties to this Amendment.

     7. This Amendment may be executed in several counterparts, each of which
will be deemed an original and all of which shall constitute one and the same
instrument and shall be governed in all respects by the laws of the Commonwealth
of Pennsylvania.

     8. As amended by this Amendment, the Formation Agreement shall remain in
full force and effect.



                                      -3-


     9. This Amendment shall be binding upon, and shall be enforceable by and
inure to the benefit of, the parties named herein and their respective
successors.

     IN WITNESS WHEREOF, the parties have executed this Amendment as of the date
first set forth above.
