                         AGREEMENT AND PLAN OF MERGER
                         ----------------------------

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of May 10,
2001, is by and between G & L ACQUISITION, LLC, a Maryland limited liability
company ("Acquiror"), and G & L REALTY CORP., a Maryland corporation (the
"Company").

                                   RECITALS

     A.    The Board of Directors of the Company (the "Board"), based upon the
recommendation of a special committee thereof (the "Special Committee"), has
determined that the Merger (as defined below) is advisable and in the best
interests of the stockholders of the Company, and the Board and the members of
Acquiror have approved the Merger upon the terms and subject to the conditions
set forth in this Agreement, whereby each issued and outstanding share of Common
Stock, par value $0.01 per share, of the Company (other than certain designated
shares) will be converted into the right to receive cash.

     B.    In order to effectuate the foregoing, Acquiror, upon the terms and
subject to the conditions set forth in this Agreement, and in accordance with
the Maryland General Corporation Law (the "MGCL") and the Maryland Limited
Liability Company Act (the "MLLCA"), will merge with and into the Company (the
"Merger").

     C.    The Special Committee has received a fairness opinion relating to the
transactions contemplated hereby as more fully described below and the Board has
resolved to recommend to the holders of Common Stock of the Company to vote to
approve the Merger.

     D.    G & L Partnership, LLC, a Delaware limited liability company of which
Acquiror is the sole member (the "Acquiror Sub"), G & L Realty Partnership,
L.P., a Delaware limited partnership ("G & L Operating Partnership"), Acquiror
and the Company have entered into a Partnership Merger Agreement of even date
herewith (the "Partnership Merger Agreement"), pursuant to which, and subject to
the terms and conditions thereof, Acquiror Sub will be merged with and into G &
L Operating Partnership (the "Partnership Merger") with G & L Operating
Partnership as the surviving entity.

     NOW, THEREFORE, in consideration of the mutual covenants, agreements,
representations and warranties contained herein, and for the purpose of setting
forth certain terms and conditions of the Merger, and the manner of carrying the
same into effect, the parties hereto agree as follows:

                                  ARTICLE I.
                                  THE MERGER

     1.1   The Merger.  Upon the terms and subject to the conditions of this
Agreement, and in accordance with the MGCL and the MLLCA, Acquiror shall be
merged with and into the Company, with the Company as the surviving entity (the
surviving entity in the Merger is sometimes referred to as the "Surviving
Corporation").

which is the third business day following satisfaction (or waiver by the parties
entitled to the benefit thereof) of the conditions set forth in Article VI

     1.3   Effective Time.  On the Closing Date, the parties shall execute and

Time") the Articles of Merger are accepted for record by the State Department of
Assessments and Taxation of the State of Maryland (the "Maryland Department"),
or at such time as Acquiror and the Company shall specify in the Articles of
Merger (not to exceed 30 days after the Articles of Merger are accepted for
record by the Maryland Department). Unless otherwise agreed, the parties shall
cause the Effective Time to occur on the Closing Date.

     1.4   Effect of Merger on Acquiror and the Company.  The parties agree to

prior to the Effective Time shall from and after the Effective Time be and
continue to be the bylaws of the Surviving Corporation until changed or amended
in accordance with applicable law.

           (d)  Organization.  At the Effective Time, the separate existence of
Acquiror shall cease, and the Company as the Surviving Corporation and successor
shall succeed to Acquiror in the manner of and as more fully set forth in

           (e)  Directors and Officers.  The directors of the Company

<PAGE>

     1.5   Effect on Securities.  At the Effective Time, pursuant to this
Agreement and by virtue of the Merger and without any action on the part of the
Company, Acquiror or the holders of any of the following securities:

           (a)  Each share of Common Stock, par value $.01 per share, of the
Company (collectively, the "Common Shares" and, individually, a "Common Share")
issued and outstanding immediately prior to the Effective Time (other than any
Common Shares to remain outstanding pursuant to Section 1.5(c)) shall be
converted into the right to receive an amount equal to $12.00 in cash, without
interest (the "Cash Merger Consideration"); the Common Shares being converted
into the right to receive the Cash Merger Consideration are hereinafter referred
to as "Cancelled Shares";

           (b)  Each issued and outstanding share of Preferred Stock, par value
$0.01 per share, of the Company (collectively, the "Preferred Shares") shall not
be converted, exchanged, cancelled or otherwise affected by the Merger and shall
remain issued and outstanding after the Merger;

           (c)  96,671 of the 360,422 Common Shares that are, on the date of
this Agreement, registered in the name of, and specified by Daniel M. Gottlieb,
and 74,674 of the 285,923 Common Shares that are, on the date of this Agreement,
registered in the name of, and specified by Steven D. Lebowitz (such persons are
individually referred to as a "Continuing Stockholder" and collectively as the
"Continuing Stockholders," and such shares are collectively referred to as the
"Continuing Shares") shall not be converted, exchanged, cancelled or otherwise
affected by the Merger and shall remain issued and outstanding after the Merger,
provided that the Continuing Shares are, at the Effective Time, so registered in
the name of the applicable Continuing Stockholder, it being understood that
additional Common Shares may be issued to the Continuing Stockholders prior to
the Effective Time in exchange for Partnership Units (as defined below) and,
subject to Section 1.5(f) below, such Common Shares shall be deemed to be
Continuing Shares;

           (d)  Each option for the purchase of Common Shares issued by the
Company and outstanding immediately prior to the Effective Time (collectively,
the "Company Options" and individually, a "Company Option"), including those
held by the Continuing Stockholders, shall be terminated and converted into the
right to receive the Option Consideration as defined and set forth in Section
1.10;

           (e)  Each unit (as defined in the Acquiror's Operating Agreement
dated as of May 4, 2001) (collectively, the "Acquiror Units," and individually,
an "Acquiror Unit") of Acquiror outstanding immediately prior to the Effective
Time shall be converted automatically into one newly-issued, fully-paid and
nonassessable share of Common Stock of the Surviving Corporation and shall cease
to exist; and

           (f)  Notwithstanding Subsection (c) above, the aggregate number of
Continuing Shares held by the Continuing Stockholders may, at the sole
discretion of the each Continuing Stockholder, be decreased (and
correspondingly, the number of Common Shares held by the Continuing Stockholders
to be converted in the Merger shall be increased) if the aggregate

                                       3
<PAGE>

purchase price of the Preferred Stock (as defined in Section 2.4) tendered in
the Offer (as defined in Section 5.3) is less than $7,750,000.

     1.6   Disbursing Agent.  Prior to the Effective Time, Acquiror shall
appoint a disbursing agent reasonably acceptable to the Company (the "Disbursing
Agent") to act as agent for the payment of the Cash Merger Consideration upon
surrender of certificates formerly representing issued and outstanding Cancelled
Shares.

     1.7   Deposit of Funds.  At the Effective Time, the Surviving Corporation
shall irrevocably deposit or cause to be deposited with the Disbursing Agent,
cash in the amount of the Aggregate Cash Merger Consideration (as defined
below). Pending distribution pursuant to Section 1.9 of the cash deposited with
the Disbursing Agent, such cash shall be held in trust for the benefit of the
holders of Cancelled Shares, and shall not be used for any other purpose. The
Surviving Corporation may direct the Disbursing Agent to invest such cash,
provided that such investments (i) shall be in obligations of or guaranteed by
the United States of America, in commercial paper obligations receiving the
highest rating from either Moody's Investors Service or Standard & Poor's, or in
certificates of deposit, bank repurchase agreements or bankers acceptances of
domestic commercial banks with capital exceeding $250,000,000 (collectively,
"Permitted Investments") or in money market funds which are invested solely in
Permitted Investments, and (ii) shall have maturities that will not prevent or
delay payments to be made pursuant to Section 1.9.

     1.8   Transmittal Letter and Instructions.  Promptly after the Effective
Time, the Surviving Corporation shall cause the Disbursing Agent to mail to each
holder of record of a certificate or certificates which immediately prior to the
Effective Time represented outstanding Cancelled Shares (collectively, the
"Certificates" and individually, a "Certificate") (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon delivery of the Certificates to the
Disbursing Agent and shall be in such form and have such other provisions as
Acquiror may reasonably specify) and (ii) instructions for use in effecting
surrender of the Certificates in exchange for the Cash Merger Consideration.
Each holder of a Certificate representing Cancelled Shares may thereafter
surrender such Certificate to the Disbursing Agent to effect the exchange of
such Certificate on such holder's behalf for a period of nine months after the
Effective Time.

     1.9   Payment of Cash for Cancelled Shares.

           (a)  After surrender to the Disbursing Agent of any Certificate which
prior to the Effective Time shall have represented Cancelled Shares in
accordance with the transmittal letter and instructions in Section 1.8, the
Surviving Corporation shall cause the Disbursing Agent to promptly distribute to
the person in whose name such Certificate shall have been registered, a check
representing the amount of cash into which such Cancelled Shares shall have been
converted at the Effective Time pursuant to Section 1.5(a). Until so surrendered
and exchanged, each such Certificate shall, after the Effective Time, be deemed
to represent only the right to receive such cash, and until such surrender and
exchange, no cash shall be paid to the holder of such outstanding Certificate in
respect thereof.

                                       4
<PAGE>

           (b)  No interest shall accrue or be payable with respect to any
amounts which any such holder shall be so entitled to receive.

           (c)  The Surviving Corporation or the Disbursing Agent shall be
authorized to pay the cash attributable to any Certificate theretofore issued
which has been lost or destroyed, upon receipt by the Surviving Corporation of
satisfactory evidence of ownership of the Cancelled Shares represented thereby
and, to the extent deemed appropriate, indemnification and/or a bond.

           (d)  If payment is to be made to a person other than the person in
whose name a surrendered Certificate, which prior to the Effective Time shall
have represented any Cancelled Shares, is registered, it shall be a condition to
such payment that the Certificate so surrendered shall be endorsed or shall
otherwise be in proper form for transfer, and that the person requesting such
payment shall have paid any transfer and other taxes required by reason of such
payment in a name other than that of the registered holder of the Certificate
surrendered or shall have established to the satisfaction of the Surviving
Corporation or the Disbursing Agent that such tax either has been paid or is not
payable.

           (e)  From and after the Effective Time, the holders of Cancelled
Shares outstanding immediately prior to the Effective Time shall cease to have
any rights with respect to such Cancelled Shares except as otherwise provided
herein.

           (f)  After the Effective Time, there shall be no transfers on the
stock transfer books of the Surviving Corporation of any Cancelled Shares which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates representing Cancelled Shares are presented to the
Surviving Corporation, they shall be cancelled and promptly exchanged for cash
as provided in Section 1.5(a) and this Section 1.9.

           (g)  All Cash Merger Consideration paid upon the surrender of
Certificates in accordance with the terms of this Section 1.9 shall be deemed to
have been paid in full satisfaction of all rights pertaining to the Cancelled
Shares formerly represented by such Certificates; provided, however, that the
Company shall transfer to the Disbursing Agent cash sufficient to pay all
dividends or make any other distributions with a record date on or prior to the
Effective Time which may have been declared or made by the Company on such
Cancelled Shares, in accordance with the terms of this Agreement or prior to the
date of this Agreement, including any dividends permitted by Section 5.7, and
which remain unpaid at the Effective Time and have not been paid prior to such
surrender.

     1.10  Treatment of Options.

           (a)  Each outstanding Company Option shall be subject to the terms of
this Agreement.

           (b)  Immediately upon execution of this Agreement, the Company shall
cause all Company Options held by the Continuing Stockholders, whether or not
then fully vested or exercisable, to become fully vested and exercisable.
Nothing in this Agreement shall be

                                       5
<PAGE>

interpreted to prevent or hinder the Continuing Stockholders from exercising
their rights under such Company Options prior to the Effective Time.

           (c)  Immediately prior to the Effective Time, the Company shall cause
each outstanding Company Option, whether or not then fully vested or
exercisable, to be deemed fully vested and exercisable, and to be terminated and
converted into the right to receive from the Surviving Corporation an amount of
cash equal to the product of (i) the number of Common Shares subject to the
Company Option (which shall have been deemed to be fully vested and exercisable)
and (ii) the excess, if any, of the Cash Merger Consideration over the exercise
price per share of such Company Option (the "Option Consideration"), with no
payment being required when the difference is not a positive number. The
Surviving Corporation shall pay each holder of the Company Options, promptly
following the Effective Time, the Option Consideration for all Company Options
held by such holder. The Board or any committee thereof responsible for the
administration of the Company's Amended and Restated 1993 Stock Incentive Plan
(the "Stock Incentive Plan") shall take any and all action necessary to
effectuate the matters described in this Section 1.10 on or before the Effective
Time. Any amounts payable pursuant to this Section 1.10 shall be subject to any
required withholding of taxes and shall be paid without interest.

     1.11  Unclaimed Consideration.  None of the Company, Acquiror, the
Surviving Corporation or the Disbursing Agent shall be liable to any person in
respect of any of the Cash Merger Consideration or Option Consideration
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law. Any portion of the Cash Merger Consideration delivered
to the Disbursing Agent pursuant to this Agreement that remains unclaimed for
nine months after the Effective Time shall be redelivered by the Disbursing
Agent to the Surviving Corporation, upon demand, and any holders of Certificates
who have not theretofore complied with the procedures set forth in this
Agreement, and the transmittal letter and instructions referenced in Section
1.8, shall thereafter look only to the Surviving Corporation for delivery of any
Cash Merger Consideration, any unpaid dividends, or Option Consideration due, as
the case may be, subject to applicable abandoned property, escheat and other
similar laws.

     The Company represents and warrants to Acquiror, except as set forth in (i)
the reports, schedules, forms, statements and other documents filed by the
Company with the Securities and Exchange Commission (the "SEC") since December
31, 1999 (the "SEC Documents") to the extent it is reasonably clear from a
reading of the disclosure in such SEC Documents that such disclosure is
applicable to the relevant representation and warranty contained herein, or (ii)
the letter of even date herewith delivered to Acquiror prior to the execution
hereof (the "Disclosure Letter") (it being understood that the Disclosure Letter
shall be arranged in Parts corresponding to the Sections contained in this
Article II, and the disclosures in any Part of the Disclosure Letter shall
qualify the representations in the corresponding Section of this Article II) as
follows:

     2.1   Organization and Good Standing.  The Company is duly organized and
validly existing in good standing under the laws of the State of Maryland, with
all requisite corporate power and authority to own, lease and operate its
properties and conduct its business and is duly qualified or registered and in
good standing as a foreign corporation authorized to do business in each of the
jurisdictions in which the character of the properties owned or held under lease
by it or the nature of the business transacted by it makes such qualification or
registration necessary, except where the failure to be so qualified or
registered would not have a Company Material Adverse Effect (as defined below).


     2.2   Subsidiaries; Investments.

           (a)  Section 2.2(a) of the Disclosure Letter sets forth as of the
date hereof (i) each Subsidiary (as defined below) of the Company, (ii) the
ownership interest therein of the Company, and (iii) if not wholly-owned by the
Company, the identity and ownership interest of each of the other owners of such
Subsidiary (it being understood that such representation with respect to
securities held by any entity other than the Company or a Subsidiary is made
only to the knowledge of the Company). As used in this Agreement, "Subsidiary"
means any corporation, partnership, limited liability company, joint venture,
trust or other legal entity of which the Company (either directly or through or
together with any other Subsidiary) owns 50% or more of the capital stock or
other equity interests of such corporation, partnership, limited liability
company, joint venture or other legal entity, including G & L Operating
Partnership, but does not include short-term money market investments and other
participation interests in short-term investments.

<PAGE>

           (b)  (i) All the outstanding shares of capital stock of each
Subsidiary that is a corporation owned by the Company or a Subsidiary have been
validly issued and are (A) fully paid, nonassessable and free of any preemptive
rights, and (B) owned by the Company or by another Subsidiary free and clear of
all pledges, claims, liens, charges, encumbrances and security interests of any
kind or nature whatsoever (collectively, "Liens") or any other limitation or
restriction (including any contractual restriction on the right to vote or sell
the same) other than restrictions under applicable securities laws; and (ii) all
equity interests in each Subsidiary that is a partnership, joint venture,
limited liability company or trust which are owned by the Company, by another
Subsidiary or by the Company and another Subsidiary, are owned free and clear of
all Liens or any other limitation or restriction (including any contractual
restriction on the right to vote or sell the same) other than restrictions under
applicable securities laws. Each Subsidiary that is a corporation is duly
incorporated and validly existing under the laws of its jurisdiction of
incorporation and has the requisite corporate power and authority to carry on
its business as now being conducted, and each Subsidiary that is a partnership,
limited liability company or trust is duly formed and existing in good standing
under the laws of its jurisdiction of formation and has the requisite
partnership, limited liability company or trust power and authority to carry on
its business as now being conducted. Each Subsidiary is duly qualified or
registered and in good standing in each jurisdiction in which the character of
the properties owned or held under lease by it or the nature of the business
transacted by it makes such qualification or registration necessary, except
where the failure to be so qualified or registered, individually or in the
aggregate, would not have a Company Material Adverse Effect.

     2.3   Authorization; Binding Agreement.

           (a)  The Company has all requisite corporate power and authority to
execute and deliver this Agreement and to consummate the transactions
contemplated hereby, subject to Stockholder Approval (as defined below). The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Board and, except for Stockholder Approval in accordance with the MGCL, and the
charter and the bylaws of the Company, no other corporate proceedings on the
part of the Company are necessary to authorize this Agreement, the Partnership
Merger Agreement, the Merger, the Partnership Merger or the transactions
contemplated hereby or thereby. This Agreement has been duly and validly
executed and delivered by the Company, and constitutes the legal, valid and
binding agreement of the Company, enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by (i) bankruptcy,
insolvency, reorganization, moratorium or other laws, now or hereafter in
effect, relating to or limiting creditors' rights generally, and (ii) general
principles of equity (whether considered in an action in equity or at law) which
provide, among other things, that the remedies of specific performance and
injunctive and other forms of equitable relief are subject to equitable defenses
and to the discretion of the court before which any proceedings therefor may be
brought.

           (b)  The Board, based upon the recommendation of the Special
Committee, has duly and validly approved and, subject to Stockholder Approval,
taken all corporate action required to be taken by it for the consummation of
the Merger and the Partnership Merger, and has adopted resolutions declaring the

the "Partnership Agreement"), are validly issued and outstanding, fully paid and
nonassessable, except to the extent provided by applicable law or the
Partnership Agreement, of which 2,333,800 are owned by the Company. Part 2.4(d)
of the Disclosure Letter sets forth the name of each holder of Partnership Units
and the number of Partnership Units owned by each such holder. The Partnership
Units are not subject to any restriction established by the Company or G & L
Operating Partnership or under applicable law (other than restrictions on sale
imposed by applicable securities laws) except as set forth in the Partnership
Agreement. G & L Operating Partnership has not issued or granted and is not a
party to any outstanding commitments of any kind relating to, or any presently

     Agreement, require the consent of any person under, or result in the
     creation of any Lien upon any property of Acquiror under, any agreement,
     indenture, lease or instrument to which Acquiror is a party or by which
     Acquiror (or its properties) may be bound, which in the aggregate would
     have a material adverse effect on Acquiror.

furnished to the Company by Acquiror specifically for inclusion in the Proxy
Statement and the Schedule 13E-3, or any amendment or supplement thereto, or

documents, at the time of filing with the SEC and at the time of the
Stockholders Meeting, not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were

Acquiror, threatened against or affecting Acquiror or the Acquiror Sub or any of
their properties or assets before any court or governmental body, department,
commission, board, bureau, agency, instrumentality or arbitrator, which,

material adverse effect upon Acquiror or (ii) to materially and adversely affect
the ability of Acquiror to carry out, or prevent or make unduly burdensome, the
Merger, the Partnership Merger or the transactions contemplated by this
Agreement.

     its stockholders) with respect to a merger, acquisition, tender offer,
     exchange offer, consolidation, share exchange, sale of assets or similar
     transaction involving all or any significant portion of the assets or any
     equity securities of the Company and its Subsidiaries, taken as a whole,
     other than the transactions contemplated by this Agreement and the
     Partnership Merger Agreement (any such proposal or offer being hereinafter
     referred to as an "Acquisition Proposal") or has engaged or shall engage in
     any negotiations concerning or provided or shall provide any confidential
     information or data to, or had or shall have any discussions with, any
     person relating to an Acquisition Proposal, or otherwise, has facilitated
     or shall facilitate any effort or has attempted or shall attempt to make or
     implement an Acquisition Proposal (for the avoidance of doubt, responding
     to an unsolicited inquiry by informing such inquirer that the Company is
     subject to this Section 4.1 and instructing such inquirer to review this
     Section of the Agreement shall not be a violation of this Section 4.1);
     provided, however, that the Company may provide confidential information to
     G. Realco LLC, Trans Healthcare, Inc., Lillibridge Health Trust and Lloyd
     Weisman (the "Existing Interested Parties"), so long as the Existing
     Interested Parties have each entered into an appropriate confidentiality
     and standstill agreement in a form satisfactory to the Company;

           (ii)   it has directed, and shall use its reasonable best efforts to
     cause, its officers, directors, employees, agents or financial advisors not
     to engage in any of the activities restricted by Section 4.1(i); provided,
     however, that this shall not prevent the Continuing Stockholders from
     taking any action prohibited by this Section 4.1 and that any such action
     shall not constitute a violation of this Section 4.1;

           (iii)  except for providing confidential information to the Existing
     Interested Parties as described in Section 4.1(i), it has ceased and caused
     to be terminated any existing activities, discussions or negotiations
     theretofore conducted with any person with respect to any Acquisition
     Proposal and has taken the necessary steps to inform the individuals or
     entities referred to in Section 4.1(i) of the obligations undertaken in
     this Section 4.1; and

           (iv)   it will notify Acquiror promptly if the Company has received
     or receives any such inquiries or proposals, or any requests for such
     information, or if any such negotiations or discussions are sought to be
     initiated or continued with it;

provided, however, that nothing contained in this Agreement shall restrict the
Board or Special Committee (or the officers, directors, employees, agents and
financial advisors of the Company acting at the direction of the Board or
Special Committee) from (i) prior to the Stockholders Meeting, entering into
discussions or negotiations with any person that makes a bona fide, written and
unsolicited Acquisition Proposal, if (A) the Board or Special Committee
determines in good faith, on advice of counsel, that the failure to take such
action would reasonably be expected to violate its duties under applicable law
and such proposal is, or is reasonably likely to be, a Superior Acquisition
Proposal (as defined below), (B) prior to entering into discussions or
negotiations with such person, the Company provides written notice to Acquiror
to the effect that it is entering into discussions with such person and (C) the
Company keeps Acquiror informed of the status (not the terms or identity of
parties) of any such discussions or negotiations; and (ii) to the extent
applicable, taking and disclosing to the Company's stockholders a position
contemplated by Rules 14d-9 and 14e-2 promulgated under the Exchange Act with
regard to an Acquisition Proposal; provided, however, that the Board or Special
Committee may not approve or recommend an Acquisition Proposal, or withdraw or
modify in a manner adverse to Acquiror its approval or recommendation of this
Agreement and the Merger, unless such Acquisition Proposal is a Superior
Acquisition Proposal.

Nothing in this Section 4.1 shall (x) permit the Company to terminate this
Agreement (except as specifically provided in Article VII hereof) or (y)  permit
the Company to enter into an agreement with respect to an Acquisition Proposal
during the term of this Agreement; provided, however, that the Board or Special
Committee may approve and recommend a Superior Acquisition Proposal and, in
connection therewith, withdraw or modify its approval or recommendation of this
Agreement and the Merger.  As used herein, "Superior Acquisition Proposal" means
a written, bona fide Acquisition Proposal made by one of the Existing Interested
Parties or any third party which the Board or the Special Committee determines
in its good faith judgment (i) to be superior from a financial point of view to
the holders of Common Shares than the transactions contemplated by this
Agreement (after consultation with the Company's financial advisor) taking into
account all of the terms and conditions of such Acquisition Proposal and of this
Agreement (including any proposal by Acquiror to amend the terms of the
transaction

                                       16
<PAGE>

contemplated by this Agreement) and (ii) is reasonably capable of being
completed, taking into account all financial, regulatory and other aspects of
such Acquisition Proposal.

take all steps necessary to cause the Stock Incentive Plan to be terminated on
or prior to the Effective Time.

           (iii)   maintain its books and records in accordance with GAAP

           (vii)   make no change in the number of its shares of capital stock,
     membership interests or units of limited partnership interest (as the case

           (xvii)  not agree, commit or arrange to take any action prohibited
     under this Section 4.3.

     4.4   Conduct of Acquiror's Business Pending Merger.  Prior to the
Effective Time, Acquiror shall use commercially reasonable efforts to obtain and
to close the funding contemplated by the Financing, or if the Financing is

funding to be made available to Acquiror and Acquiror Sub as and subject to the
conditions provided in the Financing.

     4.5   Other Actions.  Each of the Company, on the one hand, and Acquiror,
on the other hand, shall not knowingly take, and shall use commercially
reasonable efforts to cause their Subsidiaries not to take, any action that
would result in (i) any of the representations and warranties of such party
(without giving effect to any "knowledge" qualification) set forth in this
Agreement that are qualified as to materiality becoming untrue or (ii) any of
such representations and warranties (without giving effect to any "knowledge"
qualification) that are not so qualified becoming untrue in any material
respect. Acquiror and its affiliates (including the Continuing Stockholders)

Shares without the written approval of the Special Committee, other than through
the exercise of existing options, conversion rights held by such parties with
respect to Partnership Units or exchange of Partnership Units provided for in
Section 1.5(c); provided, however, that this subsection (a) shall not apply and

                             ADDITIONAL COVENANTS

     5.1   Preparation of Proxy Statement; Stockholders Meeting.

           (a)  The parties shall cooperate and promptly prepare, and the
Company shall file with the SEC as soon as practicable, a proxy statement
("Proxy Statement") with respect to the Stockholders Meeting to be held in
connection with the Merger. The parties shall cooperate and promptly prepare and
the appropriate party shall file with the SEC as soon as practicable any other
filings required under the Exchange Act ("Additional Filings"), including a Rule
13e-3 Transaction Statement on Schedule 13E-3 ("Schedule 13E-3") with respect to
the Merger to be filed jointly by the Company and Acquiror, together with any
required amendments thereto. Each of the Company and Acquiror agrees that the
written information provided by it for inclusion in the Proxy Statement and
Additional Filings, and each amendment or supplement thereto, at the time of
mailing thereof and at the time of the Stockholders Meeting, will not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

           (b)  The Company will use its reasonable best efforts, and Acquiror
will cooperate with the Company, to (i) file a preliminary Proxy Statement with
the SEC and respond to the comments of the SEC thereon, and (ii) cause a
definitive Proxy Statement to be mailed to holders of Common Shares, in each
case, as promptly as practicable (including clearing the Proxy Statement with
the SEC). The Company will notify Acquiror promptly of the receipt of any
comments from the SEC and of any request by the SEC for amendments or
supplements to the Proxy Statement or the Additional Filings or for additional
information and will supply Acquiror with copies of all correspondence between
such party or any of its representatives and the SEC with respect to the Proxy
Statement or the Additional Filings. The parties shall cooperate to cause the
Proxy Statement and any Additional Filings to comply in all material respects
with all applicable requirements of law. Whenever any event occurs which is
required to be set forth in an amendment or supplement to the Proxy Statement or
the Additional Filings, the Company, on the one hand, and Acquiror, on the other
hand, shall promptly inform the other of such occurrence and cooperate in filing
with the SEC and/or mailing to holders of Common Shares, such amendment or
supplement to the Proxy Statement.

           (c)  The Company will, as soon as practicable following the date of
this Agreement, duly call, give notice of, convene and hold a meeting of its
stockholders, such meeting to be held no sooner than 20 days nor later than 45
days following the date the Proxy Statement is mailed to the holders of Common
Shares (the "Stockholders Meeting"), for the purpose of obtaining Stockholder
Approval (as defined below).

           (d)  If on the date for the Stockholders Meeting established pursuant
to subsection (c) above, the Company has not received duly executed proxies
which, when added to

                                       20
<PAGE>

the number of votes represented in person at the Stockholders Meeting by persons
who intend to vote to approve the Merger, will constitute a sufficient number of
votes to constitute Stockholder Approval (but holders of less than a majority of
the outstanding Common Shares have indicated their intention to vote against, or
have submitted duly executed proxies voting against, approval of the Merger),
then the Company, through the Board, shall recommend one or more adjournment(s)
of the Stockholders Meeting for up to 120 days after the record date as approved
by a majority vote of holders of Common Shares present in person or by proxy.

     5.2   Access to Information.  The Company shall, and the Company shall
cause each of its Subsidiaries to, afford to Acquiror and to the officers,
employees, accountants, financial advisors, attorneys, consultants, sources of
financing and other representatives of Acquiror, reasonable access during normal
business hours prior to the Effective Time to all the properties, books,
contracts, commitments, personnel and records and, during such period, the
Company shall, and the Company shall cause each of its Subsidiaries to, furnish
promptly to Acquiror and its financing sources all other information concerning
its business, properties and personnel as Acquiror may reasonably request.
Notwithstanding anything in this Section 5.2 to the contrary, all of Acquiror's
activities pursuant to this Section 5.2 must be conducted in a manner that does
not unreasonably interfere with the ongoing operations of the Company and its
Subsidiaries.

     5.3   Tender Offer.

           (a)  The Continuing Stockholders, individually or through an entity
they will form, propose to make a tender offer (as it may be amended from time
to time, the "Offer") to purchase up to 16% of the aggregate number of Preferred
Shares, at a purchase price of $17.50 per share of Series A Preferred Stock and
$17.00 per share of Series B Preferred Stock, net to the seller in cash, without
interest, upon terms and subject to conditions determined by the Continuing
Stockholders and customary for such tender offers, provided that the acceptance
for payment and payment for the Preferred Shares shall close simultaneously
with, and be subject to consummation of, the Merger.

           (b)  As promptly as practicable following the mailing by the Company
of the Proxy Statement with the SEC, the Continuing Stockholders shall commence
the Offer, within the meaning of Rule 14d-2 under the Exchange Act, and shall
file with the SEC (i) a Tender Offer Statement on Schedule TO (the "Schedule
TO") with respect to the Offer, which shall contain as an exhibit or incorporate
by reference an offer to purchase and a related letter of transmittal and, if
required to commence the Offer, a summary advertisement (such Schedule TO and
the documents included therein pursuant to which the Offer will be made,
together with any supplements or amendments thereto, the "Offer Documents"). The
Continuing Stockholders shall cause the Offer Documents to be disseminated to
holders of Preferred Shares as and to the extent required by applicable federal
securities laws, and shall ensure that the Offer Documents comply in all
material respects with the provisions of applicable federal securities laws and,
on the date filed with the SEC and, if applicable, the date first published,
sent or given to the holders of the Preferred Shares, do not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they are made, not misleading, except that no
representation is made with respect to any information supplied by the Company
in writing for inclusion in the Offer Documents.

                                       21
<PAGE>

           (c)  The Company and its counsel shall be given a reasonable
opportunity to review and comment upon the Offer Documents prior to their filing
with the SEC or, if applicable, dissemination to the holders of Preferred
Shares. The Continuing Shareholders will notify the Company promptly of the
receipt of any comments from the SEC and of any request by the SEC for
amendments or supplements to the Offer Documents or for additional information
and will supply the Company with copies of all correspondence with the SEC with
respect to the Offer Documents. Whenever any event occurs which is required to
be set forth in an amendment or supplement to the Offer Documents, the Company,
on the one hand, and the Continuing Stockholders, on the other hand, shall
promptly inform the other of such occurrence and cooperate in filing with the
SEC and/or mailing to the holders of Preferred Shares, such amendment or
supplement.

           (d)  On or as soon as practicable after the date the Offer Documents
are filed with the SEC, the Company shall file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the
Offer (such Schedule 14D-9, as amended from time to time, the "Schedule 14D-9")
containing (unless the Special Committee or the Board, after consultation with
counsel, determines in good faith that such action would be inconsistent with
its duties to Company stockholders under applicable law) a statement that
neither the Board nor the Special Committee is expressing an opinion with
respect to the Offer and each is remaining neutral toward the Offer. The
Continuing Stockholders and their counsel shall be given reasonable opportunity
to review and comment upon the Schedule 14D-9 prior to its filing with the SEC
or dissemination to holders of Preferred Shares.

           (e)  In connection with the Offer, the Company shall instruct its
transfer agent or agents to furnish the Continuing Stockholders promptly upon
request with mailing labels containing the names and addresses of the record
holders of Preferred Shares as of a recent date and of those persons becoming
record holders subsequent to such date, together with copies of any other
information in the Company's possession or control, as the Continuing
Stockholders may reasonably request, and, to the extent reasonably available to
the Company, regarding the beneficial owners of Preferred Shares, and shall
furnish to the Continuing Stockholders such information and assistance as the
Continuing Stockholders may reasonably request in communicating the Offer to the
holders of Preferred Shares. Subject to the requirements of applicable law, and
except for such steps as are necessary to disseminate the Offer Documents, the
Continuing Stockholders shall, and shall cause their agents to, hold in
confidence the information contained in any such labels, listings and files, and
use such information only in connection with the Offer.

           (f)  The Continuing Stockholders shall apply any dividends paid on
any Preferred Shares purchased by them pursuant to the Offer, first to interest
on any personal loans secured by the Preferred Shares and next to their loans
contemplated by Section 3.10.

     5.4   Reasonable Efforts; Notification.

     Consents and Lessor Consents being referred to herein collectively as the
     "Required Consents") in form reasonably satisfactory to the Company and
     Acquiror; and

                (iii) use all reasonable efforts to take, or cause to be taken,
     all other action and do, or cause to be done, all other things necessary,
     proper or appropriate to consummate and make effective the transactions
     contemplated by this Agreement and the Partnership Merger Agreement,
     subject in the case of the Company to the exercise by the Board or Special
     Committee of its duties under applicable law; provided, however, that

     pay any money or other consideration or to incur any liability or other
     obligation.

           (b)  The Company shall give prompt written notice to Acquiror (i) if

Agreement; provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

condition or agreement to be complied with or satisfied by Acquiror under this
Agreement; provided, however, that no such notification shall affect the
representations, warranties, covenants or agreements of the parties or the
conditions to the obligations of the parties under this Agreement.

     5.5   Public Announcements.  Acquiror and the Company will consult with
each other before issuing, and provide each other the opportunity to review and
comment upon, any press release or other written public statements with respect
to the transactions contemplated by this Agreement, and shall not issue any such

person in his capacity as an officer or director, or (ii) this Agreement or the
Partnership Merger Agreement or the transactions contemplated by this Agreement
or the Partnership Merger Agreement, whether in any case asserted or arising
before or after the Effective Time, the Surviving Corporation (the "Indemnifying
Party") shall from and after the Effective Time indemnify and hold harmless the
Indemnified Parties from and against any losses, claims, liabilities, reasonable
expenses (including reasonable attorneys' fees and expenses), judgments, fines
or amounts paid in settlement arising out of or relating to any such Claims. The
Surviving Corporation and the Indemnified Parties hereby agree to use their
reasonable best efforts to cooperate in the defense of such Claims. In
connection with any such Claim, the Indemnified Parties shall have the right to
select and retain counsel, subject to the consent of the Indemnifying Party
(which consent shall not be unreasonably withheld or delayed). The Company shall
bear the fees and expenses of only one counsel on behalf of the Indemnifying
Parties, provided that if representation by the same counsel would involve
actual or potential conflict of interest for such counsel that an Indemnified
Party is not willing to waive, the Company shall bear the fees and expenses of
separate counsel for such Indemnified Party. In addition, after the Effective
Time, in the event of any such threatened or actual Claim, the Indemnifying
Party shall promptly pay and advance reasonable expenses and costs incurred by
each Indemnified Party as they become due and payable in advance of the final
disposition of the Claim to the fullest extent and in the manner permitted by
law. Notwithstanding the foregoing, the Indemnifying Party shall not be
obligated to advance any expenses or costs prior to receipt of a written
affirmation by the Indemnified Party of his or her good faith belief that the
standard of conduct necessary for indemnification under applicable law has been
met and an undertaking by or on behalf of the Indemnified Party, such
undertaking to be accepted without regard to the

                                       24
<PAGE>

creditworthiness of the Indemnified Party, to repay any expenses advanced if it
shall ultimately be determined that the Indemnified Party is not entitled to be
indemnified against such expense. Notwithstanding anything to the contrary set
forth in this Agreement, the Indemnifying Party (i) shall not be liable for any
settlement effected without its prior written consent (which consent shall not
be unreasonably withheld or delayed), and (ii) shall not have any obligation
hereunder to any Indemnified Parties to the extent that a court of competent
jurisdiction shall determine in a final and nonappealable order that such
indemnification is prohibited by applicable law. In the event of a final and
nonappealable determination by a court that any payment of expenses is
prohibited by applicable law, the Indemnified Parties shall promptly refund to
the Indemnifying Party the amount of all such expenses theretofore advanced
pursuant hereto. Any Indemnified Parties wishing to claim indemnification under
this Section 5.6, upon learning of any such Claim, shall promptly notify the
Indemnifying Party of such Claim and the relevant facts and circumstances with
respect thereto; provided that the failure to provide such notice shall not
affect the obligations of the Indemnifying Party except to the extent such
failure to notify materially prejudices the Indemnifying Party's ability to
defend such Claim; and provided further that no Indemnified Parties shall be
obligated to provide any notification pursuant to this Section 5.6 prior to the
Effective Time.

           (c)  For a period of five years after the Effective Time, the
Surviving Corporation shall use its reasonable efforts to maintain in effect the
current policies of directors' and officers' liability insurance maintained by
the Company (provided that the Surviving Corporation may substitute therefor
policies of at least the same amounts and comparable coverage containing terms
and conditions which are comparable thereto; and provided further that such
policies may have higher deductibles than the current policy) with respect to
claims arising from facts or events which occurred at or before the Effective
Time; provided, however, that the Surviving Corporation shall not be obligated
to make annual premium payments for such insurance to the extent such premiums
exceed 150% of the premiums paid as of the date of this Agreement by the Company
for such insurance but in such event shall use reasonable efforts to provide the
maximum coverage available at 150% of such premiums.

           (d)  This Section 5.6 is intended for the irrevocable benefit of, and
to grant third-party rights to, the Indemnified Parties and their successors,
assigns and heirs and shall be binding on all successors and assigns of
Surviving Corporation. Each of the Indemnified Parties shall be entitled to
enforce the covenants contained in this Section 5.6 and the Company acknowledges
and agrees that each Indemnified Party would suffer irreparable harm and that no
adequate remedy at law exists for a breach of such covenants and such
Indemnified Party shall be entitled to injunctive relief (without posting bond)
and specific performance in the event of any breach of any provision in this
Section 5.6.

           (e)  Notwithstanding anything to the contrary contained elsewhere in
this Agreement, the Surviving Corporation's agreement set forth in this Section
5.6 shall be limited to cover Claims only to the extent that those Claims are
not covered, paid and extinguished pursuant to the Company's directors' and
officers' insurance policies referenced in subsection (c) above (or any
substitute policies permitted by such subsection).

     5.7   Declaration of Dividends and Distributions.  From and after the date
of this Agreement, the Company shall not make any dividend or other distribution
to its stockholders

                                       25
<PAGE>

without the prior written consent of Acquiror, except for (i) payment of
dividends on Common Shares consistent with prior practice exemplified by the
last full quarter prior to the date of this Agreement, and (ii) payment of
monthly dividends on Preferred Shares in the amounts provided for in its
Articles Supplementary. From and after the date of this Agreement, G & L
Operating Partnership shall not make any distribution to its partners except a
distribution per Partnership Unit in the same amount as dividends on the Common
Shares and Preferred Shares with the same record and payment dates as such
dividends on the Common Shares and Preferred Shares. The foregoing restrictions,
and Section 4.3(ix), shall not apply, however, to the extent a distribution by
the Company is necessary for the Company to maintain REIT status or to prevent
the Company from having to pay federal income or excise tax.

     5.8   Stockholder Claims.  The Company shall not settle or compromise any
claim relating to the transactions contemplated by this Agreement or by the
Partnership Merger Agreement brought by any current, former or purported holder
of any securities of the Company or G & L Operating Partnership without the
prior written consent of Acquiror, which consent will not be unreasonably
withheld or delayed.

     5.9   Cooperation with Proposed Financing.  At the request of Acquiror, the
Company shall reasonably cooperate with Acquiror in connection with the proposed
Financing or alternative financing of the transactions contemplated by this
Agreement and the Partnership Merger Agreement, and execute and deliver at the
Closing the definitive financing agreements as contemplated by the Financing
Commitment or any alternative financing, provided that such requested actions do
not unreasonably interfere with the ongoing operations of the Company and its
Subsidiaries, taken as a whole.

     5.10  Conversion of Partnership Units.  The Company shall use its
reasonable commercial efforts to cooperate with the Continuing Stockholders with
respect to any exercise of the Continuing Stockholders' conversion rights in G&L
Operating Partnership, so as to facilitate their tax and estate planning
concerns, provided that it does not result in additional expense to the Company.

     5.11  Exchange of Partnership Units.  The Company or its affiliates shall
exchange a portion of its interest in 435 North Roxbury Drive, Ltd., a
California limited partnership, for Partnership Units held by Reese L. Milner
and his affiliates, on terms as shall be satisfactory to Mr. Milner and the
Company, considering that this is a noncash transaction and involves a minority
interest, provided that the remaining Partnership Units held by Mr. Milner and
his affiliates will entitle them on conversion to no more than 5% of the Common
Shares outstanding immediately after the Effective Time.

     5.12  Spinoff of Non-MOB Assets.  If required by the terms of the
Financing, the Company shall, with the approval of holders of Partnership Units,
and prior to the Effective Time, transfer to a newly-formed limited partnership
the assets of the Partnership that are not related to medical office buildings.

     5.13  Section 16 Matters.  Prior to the Effective Time, the Company shall
take all such steps as may be required to cause any dispositions of Common
Shares (including the issuance of shares pursuant to stock options, Partnership
Units and other derivative securities with respect to

                                       26
<PAGE>

Common Shares) resulting from the transactions contemplated by this Agreement by
each individual who is subject to the reporting requirements of Section 16(a) of
the Exchange Act with respect to the Company, to be exempt under Rule 16b-3
promulgated under the Exchange Act, such steps to be taken in accordance with
the No-Action letter dated January 12, 1999, issued by the SEC to Skadden, Arps,
Slate, Meagher & Flom LLP.

or approval (including the Required Consents), or to whom notice, is required in
connection with the execution or delivery by the Company or Acquiror of this
Agreement, the Partnership Merger Agreement or consummation of the transactions
contemplated hereby or thereby.

           (c)  Fairness Opinion.  The fairness opinion delivered by HLHZ

Agreement and, except as contemplated by the Merger or as otherwise contemplated

Effective Time, and the Company shall have received a certificate from Acquiror
signed by the members to that effect.

           (b)  Performance of Obligations.  Acquiror shall have performed in
all material respects all obligations required to be performed by it under this
Agreement prior to the Effective Time, and the Company shall have received a

obligations of Acquiror to effect the Merger shall be subject to the
satisfaction, at or prior to the Effective Time, of each of the following
additional conditions, unless waived by Acquiror in writing:

Company signed by an executive officer to that effect. For purposes of this
subsection (d), it is understood and agreed that, notwithstanding the definition
in Section 2.5, a Company Material Adverse Effect also shall be deemed to have
occurred, without regard to any certificate provided pursuant to the first
sentence of this subsection (d), if, as a result of a change of law after the

Time) as a REIT. For this purpose, the term "change in law" shall mean any
amendment to or change (including any announced prospective change having a

interpreting such federal tax laws (whether or not such pronouncement or
decision is issued to, or in connection with, a proceeding involving the Company
or a Subsidiary or is subject to review or appeal).

                                  TERMINATION

     7.1   Termination.  This Agreement may be terminated, and the Merger
abandoned, at any time prior to the Effective Time, by:

           (i)    mutual written consent of the Company and Acquiror;

           (ii)   either party, by written notice to the other party, if the
     Merger shall not have been consummated by October 15, 2001; provided,
     however, that the right to terminate this Agreement under this clause (ii)
     shall not be available to any party whose failure to perform any obligation
     or to comply with any material agreement or covenant under this Agreement
     has been the cause of, or resulted in, the failure of the Effective Time to
     occur on or before that date;

           (iii)  Acquiror, by written notice to the Company, if prior to the
     Stockholders Meeting, the Board or the Special Committee (A) shall withdraw
     or modify in any manner adverse to Acquiror its approval or recommendation
     of this Agreement or the Merger, (B) shall approve or recommend any
     Acquisition Proposal by a party other than Acquiror, or (C) shall resolve
     to take any of the actions specified in clause (A) or (B);

           (iv)   the Company, by written notice to Acquiror, if the Board or
     the Special Committee determines that an Acquisition Proposal constitutes a
     Superior Acquisition Proposal and, in its good faith judgment, after
     consultation with counsel, that failing to terminate this Agreement would
     be inconsistent with the Board's or the Special Committee's duties under
     the MGCL, provided that the Company has complied in all material respects
     with all the provisions of Section 4.1, including the notice provisions
     therein;

           (v)    either party, by written notice to the other party, if at any
     time (A) any of the representations or warranties of the other party set
     forth in this Agreement that are qualified as to materiality shall not be
     true and correct in any respect or any such representations or warranties
     that are not so qualified shall not be true and correct in any material
     respect, or (B) the other party shall have failed to perform in any
     material respect any material obligation or to comply in any material
     respect with any material agreement or covenant of the other party to be
     performed or complied with by it under this Agreement and such untruth,
     incorrectness or failure cannot be or has not been cured within 20 business
     days after the giving of written notice to the other party; provided,
     however, that the right to terminate this Agreement under clause (A) shall
     not be available to Acquiror to the extent based on any representation or
     warranty of the Company that a Continuing Stockholder actually knew was not
     true or correct in a material respect when made, and the right to terminate
     this Agreement under clause (B) shall not be available to Acquiror to the
     extent based on a failure to perform any obligation or to comply with any
     agreement or covenant caused by action taken by a Continuing Stockholder.

                                       29
<PAGE>

           (vi)    Acquiror, by written notice to the Company, if after the date
     hereof there shall have occurred a Company Material Adverse Effect;

           (vii)   the Company, by written notice to Acquiror, if the Board or
     Special Committee, in its good faith exercise of its business judgment
     (based on the advice of counsel), has determined that the Board continuing
     to recommend to the holders of Common Shares the approval of the Merger
     would be reasonably likely to be a breach of the duties of the Board under
     the MGCL;

           (viii)  the Company (unless the Company is in breach of its
     obligations under Section 5.1) or Acquiror, by written notice to the other,
     if upon a vote at the Stockholders Meeting, the Stockholder Approval shall
     not have been obtained;

           (ix)    either party, by written notice to the other party, if any
     court of competent jurisdiction or other governmental entity shall have
     issued an order, decree or ruling or taken any other action permanently
     enjoining, restraining or otherwise prohibiting the Merger and such order,
     decree, ruling or other action shall have become final and nonappealable;
     or

           (x)     Acquiror, by written notice to the Company, if the Company
     shall have failed to hold the Stockholders Meeting by September 15, 2001,
     and either of the following shall have occurred prior to such date: (A) any
     corporation, partnership, person, other entity or "group" (as referred to
     in Section 13(d)(3) of the Exchange Act) other than Acquiror or any of its
     affiliates (collectively, "Third Persons") shall have become the beneficial
     owner (as defined in Rule 13d-3 promulgated under the Exchange Act) of more
     than 15% of the outstanding Common Shares; or (B) any Third Person shall
     have made, proposed, communicated or disclosed in a manner which is or
     becomes known: (i) by stockholders beneficially owning 5% or more of the
     outstanding Common Shares or (ii) by any director or officer of the
     Company, an intention to make a bona fide Acquisition Proposal, unless in
     the case of the condition in clause (B), the Company is able to sustain the
     burden of showing that the failure to hold the Stockholders Meeting was
     caused primarily by factors other than knowledge of such intention to make
     an Acquisition Proposal.

Any action to be taken to terminate this Agreement under this Section shall be
taken by, or pursuant to authority granted by, the Board (as recommended by the
Special Committee) or Acquiror's members, as the case may be.

     7.2   Effect of Termination.  In the event of the termination of this
Agreement under Section 7.1, this Agreement shall thereafter become void and
have no effect and no party hereto shall have any liability to any other party
hereto or its stockholders, members, directors or officers in respect thereof;
provided that the provisions of Article VIII, Sections 4.7, 5.10, 5.11, 7.3 and
this Section 7.2 shall remain in full force and effect and survive any
termination of this Agreement until the expiration of such provisions in
accordance with their terms.

     7.3   Expenses and Termination Fee.

           (a)  Except as otherwise provided in this Section 7.3, the Company on
the one hand, and Acquiror, Acquiror Sub and the Continuing Stockholders
(collectively the "Acquiror Parties"), on the other hand, shall bear their own
fees and expenses in connection with the negotiation and performance of this
Agreement and the Partnership Merger Agreement, and the consummation of the
Merger and the transactions contemplated hereby (including the Offer) and
thereby, provided that as of the Closing the Company shall pay or reimburse the
Acquiror Parties for all their fees and expenses to the extent they have not
been paid or reimbursed under subsection (b) below.

           (b)  The Company agrees to pay or reimburse the Acquiror Parties,
promptly following receipt of reasonable supporting documentation, for up to
$400,000 of their fees and expenses incurred in connection with the negotiation
and performance of this Agreement and the Partnership Merger Agreement, and the
consummation of the transactions contemplated hereby (excluding the Offer) and
thereby, including any and all fees and expenses of accountants, financial
advisors, attorneys and consultants engaged by the Acquiror Parties or by any
persons or entities proposing to provide financing, as well as points, charges
for interest rate protection, fees or cost reimbursements paid or owed to the
financing sources of the Acquiror Parties. Such payment or reimbursement by the
Company shall be nonrefundable, except that Acquiror Parties will refund any
such amounts paid or reimbursed by the Company in the event they materially
breach their obligations under this Agreement.

           (c)  If the Company terminates this Agreement pursuant to Section
7.1(iv) or (vii), or if Acquiror terminates this Agreement pursuant to Section
7.1(iii) or (x), then the Company shall (A) pay to Acquiror, within two business
days, in immediately available funds, the sum of $750,000, and (B) promptly upon
receipt, but in no event later than two business days following receipt, of
reasonable supporting documentation, pay or reimburse Acquiror Parties for all
their reasonable fees and expenses, to the extent unpaid, in connection with the
negotiation and performance of this Agreement and the Partnership Merger
Agreement, and the consummation of the transactions contemplated hereby
(excluding the Offer) and thereby, including any and all reasonable fees and
expenses of accountants, financial advisors, attorneys and consultants engaged
by the Acquiror Parties or by any persons or entities proposing to provide
financing, as well as points, fees or cost reimbursements paid or owed to the
financing sources of the Acquiror Parties. If Acquiror terminates this Agreement
pursuant to Section 7.1(vi) and such Company Material Adverse Effect was caused
by a Force Majeure Event (as defined below), then the Company shall pay or
reimburse Acquiror Parties for 50% of their reasonable fees and expenses to the
extent set forth in clause (B) of this subsection (c). The Company's payment of
the termination fee and other fees and expenses set forth in this subsection (c)
shall be the sole and exclusive remedy of Acquiror against the Company and any
of its Subsidiaries, and their respective directors, officers, employees,
agents, advisors or other representatives in respect of the occurrence giving
rise to such payment.

                                 MISCELLANEOUS

     8.1   Non-Survival of Representations and Warranties.  The respective
representations and warranties of the Company and Acquiror contained herein or
in any certificate delivered pursuant hereto shall expire with, and be
terminated and extinguished upon, consummation of the Merger, and thereafter
none of the Company or Acquiror or any officer, director or member thereof shall
be under any liability whatsoever with respect to any such representation or
warranty. This Section 8.1 shall have no effect upon any other obligation of the
parties hereto, whether to be performed before or after consummation of the
Merger.

     8.2   Amendment.  This Agreement may not be amended except by an instrument
in writing signed on behalf of each of the parties hereto by action taken by the
Board (as recommended by the Special Committee) and by Acquiror's members;
provided, however, that (i) after Stockholder Approval, no amendment may be made
which reduces the amount or changes the form of consideration to be received by
the Public Stockholders in the Merger or otherwise changes or effects any change
which would adversely affect the Public Stockholders prior to the effectiveness
of the Merger without the further approval of the holders of Common Shares, and
(ii) after the Effective Time, no amendment may be made to Section 5.6.

     8.3   Waiver.  At any time prior to the Effective Time, whether before or
after the Stockholders Meeting, any party hereto, by action taken by the Board
(as recommended by the Special Committee) or Acquiror's members, as the case may
be, may (i) extend the time for the performance of any of the obligations or
other acts of any other party hereto or (ii) waive compliance with any of the
agreements of any other party or with any conditions to its own obligations;
provided, however, that after Stockholder Approval, no waiver may be made which
reduces the amount or changes the form of consideration to be received by the
Public Stockholders in the Merger or otherwise changes or effects any change
which would adversely affect the Public Stockholders prior to the effectiveness
of the Merger without the further approval of the holders of Common Shares.

of California, without giving effect to the principles of conflict of laws
thereof.

     8.12  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same agreement.

     8.13  Severability.  If any term or provision of this Agreement is invalid
or unenforceable in any jurisdiction by reason of any law or public policy, all
other terms and provisions of this Agreement shall nevertheless remain in full
force and effect so long as the economic and legal substance of the transactions
contemplated hereby are not affected in any manner materially adverse to any
party. Upon such determination that any term is invalid or unenforceable, the
parties shall negotiate in good faith to modify this Agreement so as to effect
