<PAGE>


foregoing, and subject thereto, at the Effective Time of the Merger, (a) the

     Section 2.5 CHARTER; BYLAWS.

     (a) At the Effective Time and without any further action on the part of the
Company or HCPI, the charter, as amended, of HCPI as in effect at the Effective
Time shall be the charter (the "Charter") of the Surviving Corporation until
duly amended as provided for therein or under the MGCL.

     (b) At the Effective Time and without any further action on the part of the
Company or HCPI, the bylaws, as amended, of HCPI as in effect at the Effective
Time shall be the bylaws (the "Bylaws") of the Surviving Corporation until duly
amended as provided for therein and under the MGCL.

     Section 2.6 DIRECTORS AND OFFICERS. The directors of HCPI at the Effective
Time shall be the initial directors of the Surviving Corporation, each to hold
office in accordance with the Charter and Bylaws of the Surviving Corporation,
and the officers of HCPI at the Effective Time shall be the initial officers of
the Surviving Corporation, in each case until their respective successors are
duly elected or appointed (as the case may be) and qualified or until their
earlier death, resignation or removal in accordance with the Charter and Bylaws.

     Section 2.7 CONVERSION OF SECURITIES. At the Effective Time, by virtue of
the Merger and without any action on the part of HCPI, the Company or the holder
of any of the following securities:

     (a) Subject to Section 2.9, each share of Company Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares of
Company Common Stock to be canceled in accordance with Section 2.7(c) hereof)
together with the Company Rights attached thereto or associated therewith, shall
be converted into 0.78 fully paid and nonassessable shares (rounded to the
nearest ten-thousandth of a share) (as adjusted as set forth in subsection (e)
of this Section 2.7, the "Exchange Ratio") of HCPI Common Stock (the "Common
Merger Consideration"). Pursuant to the HCPI Rights Plan, one HCPI Right will be
attached to each share of HCPI Common Stock issued upon conversion of Company
Common Stock in accordance with this Section 2.7(a), and, prior to the
Distribution Date (as defined in the HCPI Rights Plan) all references in this
Agreement to HCPI Common Stock shall be deemed to


                                       13
<PAGE>


include the HCPI Rights. As of the Effective Time, all such shares of Company
Common Stock and all Company Rights shall no longer be outstanding and shall
automatically be canceled and retired and shall cease to exist, and each holder
of a Certificate representing any such shares of Company Common Stock shall
cease to have any rights with respect thereto, except, subject to Section 2.10,
rights as a holder of HCPI Common Stock and the right to receive (i)
certificates representing the Common Merger Consideration, and (ii) any cash in
lieu of fractional shares of HCPI Common Stock to be paid in consideration
therefor upon surrender of such Certificate in accordance with Section 2.9.

     (b) Subject to Section 2.9, each share of Company Series B Preferred Stock
issued and outstanding immediately prior to the Effective Time (other than
shares of Company Series B Preferred Stock to be canceled in accordance with
Section 2.7(c) hereof) shall be converted into one share of HCPI Series C
Preferred Stock, having substantially the same rights and preferences as the
Company Series B Preferred Stock, as set forth on Exhibit B attached hereto (the
"Series B Preferred Merger Consideration"). As of the Effective Time, all such
shares of Company Series B Preferred Stock shall no longer be outstanding and
shall automatically be canceled and retired and shall cease to exist, and each
holder of a Certificate representing any such shares of Company Series B
Preferred Stock shall cease to have any rights with respect thereto, except,
subject to Section 2.10, rights as a holder of HCPI Series C Preferred Stock and
the right to receive certificates representing the Series B Preferred Merger
Consideration.

     (c) Each share of Company Common Stock and Company Series B Preferred Stock
that is (i) held in the treasury of the Company or owned by any Subsidiary of
the Company (other than shares of Company Common Stock and Company Series B
Preferred Stock held or owned on behalf of third parties) or (ii) owned by HCPI
or any Subsidiary of HCPI, in each case immediately prior to the Effective Time,
shall, by virtue of the Merger and without any action on the part of the holder
thereof, be canceled and retired without any conversion thereof and no payment
or distribution of any consideration shall be made with respect thereto.

     (d) Each share of HCPI Stock or other capital stock of HCPI issued and
outstanding immediately prior to the Effective Time shall remain outstanding and
shall be unchanged after the Merger.

     (e) The Exchange Ratio shall be adjusted to reflect fully the effect of any
stock split, reverse split, stock dividend (including any dividend or
distribution of securities convertible into HCPI Common Stock, but expressly
excluding any dividends or distributions payable on HCPI Common Stock in cash),
reorganization, recapitalization or other like change with respect to HCPI
Common Stock occurring after the date hereof and prior to the Effective Time.

     Section 2.8 TREATMENT OF COMPANY OPTIONS, COMPANY DIVIDEND EQUIVALENT
RIGHTS AND COMPANY DEFERRED DIRECTORS FEES.

     (a) The Board of Directors of the Company (the "Company Board"), or, if
appropriate, any committee thereof, shall adopt appropriate resolutions and take
all other


                                       14
<PAGE>


necessary actions (including plan amendments) to cause prior to the Effective
Time each outstanding Company Option which has not vested immediately prior to
the Effective Time to become vested and fully exercisable.

     (b) Prior to the Effective Time, the Company and the Company Board (or, if
appropriate, any committee thereof) shall use its reasonable efforts to cause
each then outstanding Company Option, whether vested or unvested, to be canceled
immediately prior to the Effective Time, with the holder thereof becoming
entitled to receive an amount of cash from the Company equal to the product of
(x) the amount, if any, by which (1) the product of (a) the closing price per
share of HCPI Common Stock on the NYSE on the most recent trading day
immediately preceding the Effective Time, and (b) the Exchange Ratio, exceeds
(2) the exercise price per share of Company Common Stock subject to such Company
Option (whether vested or unvested), and (y) the number of shares of Company
Common Stock issuable pursuant to the unexercised portion of such Company
Option, less any required withholding of taxes (such amount being hereinafter
referred to as the "Option Consideration"). The Option Consideration shall be
paid by the Company immediately prior to the Effective Time. The cancellation of
a Company Option in exchange for the Option Consideration shall be deemed a
release of any and all rights the holder had or may have had in respect of such
Company Option, and any required consents received from Company Option holders
shall so provide.

     (c) In the event that any Company Options are not canceled in accordance
with the provisions of Section 2.8(b), such Company Options (the "Remaining
Options") shall be subject to the following provisions of this Section 2.8(c).
Prior to the Effective Time, the Company Board (or, if appropriate, any
committee thereof) and the Board of Directors of HCPI (the "HCPI Board") (or, if
appropriate, any committee thereof) shall adopt appropriate resolutions and take
all other actions necessary to provide that effective at the Effective Time,
each outstanding Remaining Option shall be assumed by HCPI and shall continue in
effect on the same terms and conditions as in effect immediately prior to the
Effective Time (subject to the provisions of Section 2.8(a) and the adjustments
in this Section 2.8(c)) and each such Remaining Option shall be converted
automatically into an option (a "New Option") to purchase the number of shares
of HCPI Common Stock, determined as provided below, at the exercise price,
determined as provided below:

          (i) The number of shares of HCPI Common Stock to be subject to the New
     Option shall be equal to the product of (x) the number of shares of Company
     Common Stock remaining subject (as of immediately prior to the Effective
     Time) to the Remaining Option multiplied by (y) the Exchange Ratio,
     provided that the number of shares of HCPI Common Stock resulting therefrom
     shall be rounded to the nearest whole share of HCPI Common Stock.

          (ii) The exercise price per share of HCPI Common Stock under the New
     Option shall be equal to (x) the exercise price per share of the Company
     Common Stock under the Remaining Option, divided by (y) the Exchange Ratio,
     provided that such exercise price shall be rounded to the nearest whole
     cent.

                                       15
<PAGE>



The adjustment provided herein with respect to any Remaining Option which is an
"incentive stock option" (as defined in Section 422 of the Code) shall be, and
is intended to be, effected in a manner which is consistent with Section 424(a)
of the Code. Except as provided in this Section 2.8, after the Effective Time,
each New Option shall be exercisable upon the same terms and conditions as were
applicable to the related Remaining Option immediately prior to the Effective
Time (except that with regard to such New Option, any references to the Company
shall be deemed, as appropriate, to mean HCPI). HCPI shall take all action
necessary, on or prior to the Effective Time, to authorize and reserve a number
of shares of HCPI Common Stock sufficient for issuance upon the exercise of New
Options as contemplated by this Section 2.8.

     (d) HCPI shall file on or prior to the Effective Time, a registration
statement on Form S-8 (or any successor or other appropriate form) registering a
number of shares of HCPI Common Stock to be issued in connection with the
exercise of the New Options as determined in this Section 2.8.

     (e) Prior to the Effective Time, the Company and the Company Board (or, if
appropriate, any committee thereof) shall cause each then outstanding Executive
Company Dividend Equivalent Right to be canceled prior to the Effective Time,
with the holder thereof receiving in consideration of such cancellation an
amount of cash as determined pursuant to the terms of his Company Employment
Contract, less any required withholding of taxes (such amount being hereinafter
referred to as the "Executive DER Consideration"). The Executive DER
Consideration shall be paid by the Company prior to the Effective Time. The
cancellation of an Executive Company Dividend Equivalent Right in exchange for
the Executive DER Consideration shall be deemed a release of any and all rights
the holder had or may have had in respect of such Executive Company Dividend
Equivalent Right.

     (f) Prior to the Effective Time, the Company and the Company Board (or, if
appropriate, any committee thereof) and the HCPI Board (or, if appropriate, any
committee thereof) shall adopt appropriate resolutions and take all other
actions necessary to provide that effective at the Effective Time, all
outstanding Company Deferred Directors Fees shall be assumed by HCPI on the same
terms and conditions as in effect immediately prior to the Effective Time
(subject to adjustments in this Section 2.8(f)) (except that any references to
the Company shall be deemed, as appropriate, to mean HCPI) and the right to
receive Company Common Stock in respect of each such Company Deferred Directors
Fees shall be converted automatically into a right to acquire or receive HCPI
Common Stock; provided that the number of shares of HCPI Common Stock to be
subject to such Company Deferred Directors Fees (including any Company Dividend
Equivalent Rights appurtenant thereto) accumulated immediately prior to the
Effective Time shall be equal to the product of (x) the number of shares of
Company Common Stock subject (as of immediately prior to the Effective Time) to
the Company Deferred Directors Fees (and accumulated Company Dividend Equivalent
Rights appurtenant thereto) multiplied by (y) the Exchange Ratio; provided that
any fractional shares of HCPI Common Stock resulting therefrom shall be rounded
to the nearest whole share of HCPI Common Stock; provided, further, that, solely
with respect to each holder of Company Deferred Directors Fees who is not a
director of the Surviving Corporation immediately following the Effective Time,
HCPI shall distribute promptly following the Effective Time shares of HCPI


                                       16
<PAGE>


Common Stock subject to said Company Deferred Directors Fees (and accumulated
Company Dividend Equivalent Rights appurtenant thereto) in accordance with the
terms and conditions thereof as in effect immediately prior to the Effective
Time, and such Company Deferred Directors Fees (and accumulated Company Dividend
Equivalent Rights appurtenant thereto) shall thereupon terminate.

     Section 2.9 FRACTIONAL INTERESTS. Notwithstanding any other provision of
this Agreement, no certificates or scrip representing fractional shares of HCPI
Common Stock shall be issued in connection with the Merger, and such fractional
interests will not entitle the owner thereof to any rights of a stockholder of
HCPI. In lieu of any such fractional interests, each Company Common Holder
exchanging Certificates pursuant to Section 2.7(a) who would otherwise have been
entitled to receive a fraction of a share of HCPI Common Stock (after taking
into account all shares of Company Common Stock then held of record by such
Company Common Holder) shall receive cash (without interest) in an amount equal
to such Company Common Holder's proportionate interest in the net proceeds from
the sale or sales in the open market by the Exchange Agent, on behalf of all
such Company Common Holders, of the aggregate fractional HCPI Common Stock that
would have been otherwise issuable pursuant to Section 2.7. As soon as
practicable following the Effective Time, the Exchange Agent shall determine the
excess of (i) the number of full shares of HCPI Common Stock delivered to the
Exchange Agent by HCPI over (ii) the aggregate number of full shares of HCPI
Common Stock to be distributed to Company Common Holders (such excess being
herein called the "Excess Shares"), and the Exchange Agent, as agent for the
former Company Common Holders, shall sell the Excess Shares at the prevailing
prices on the NYSE. The sale of the Excess Shares by the Exchange Agent shall be
executed on the NYSE through one or more member firms of the NYSE and shall be
executed in round lots to the extent practicable. HCPI shall pay all
commissions, transfer Taxes and other out-of-pocket transaction costs, including
the expenses and compensation of the Exchange Agent, incurred in connection with
such sale of Excess Shares. Until the net proceeds of such sale have been
distributed to the former Company Common Holders, the Exchange Agent will hold
such proceeds in trust for such former stockholders (the "Fractional Securities
Fund"). As soon as practicable after the determination of the amount of cash to
be paid to former Company Common Holders in lieu of any fractional interests,
the Exchange Agent shall make available in accordance with this Agreement such
amounts to such former Company Common Holders. The Exchange Agent shall invest
the Fractional Securities Fund as directed by HCPI, on a daily basis. Any
interest and other income resulting therefrom shall be paid to HCPI.

     Section 2.10 SURRENDER OF SHARES OF COMPANY STOCK; STOCK TRANSFER BOOKS.

     (a) Prior to the Closing Date, HCPI shall designate a bank or trust company
reasonably acceptable to the Company to act as agent for the Company Common
Holders and Company Preferred Holders in connection with the Merger (the
"Exchange Agent"). The Exchange Agent shall (i) receive certificates
representing the Merger Consideration to which Company Common Holders and
Company Preferred Holders shall become entitled pursuant to Sections 2.7(a) and
(b) and (ii) receive and thereafter sell the Excess Shares pursuant to Section
2.9. Prior to the Effective Time, HCPI will make available to the Exchange Agent
sufficient

                                       17
<PAGE>



certificates representing shares of HCPI Common Stock and HCPI Series C
Preferred Stock to make all exchanges pursuant to Section 2.10(b). The Exchange
Agent shall cause the certificates representing shares of HCPI Common Stock and
HCPI Series C Preferred Stock deposited by HCPI to be (i) held for the benefit
of the Company Common Holders and Company Preferred Holders and (ii) promptly
applied to making the exchanges and payments provided for in Section 2.10(b).
Such shares of HCPI Common Stock, HCPI Series C Preferred Stock and cash
resulting from the Fractional Securities Fund shall not be used for any purpose
that is not provided for herein.

     (b) Promptly after the Effective Time, HCPI shall mail, or shall cause the
Surviving Corporation to mail, to each Company Common Holder and each Company
Preferred Holder (i) a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Exchange Agent) and
(ii) instructions for use in effecting the surrender of the Certificates in
exchange for the Merger Consideration and any cash in lieu of fractional shares
pursuant to Section 2.9. Upon surrender to the Exchange Agent of a Certificate,
together with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, and such other documents as may be
reasonably required pursuant to such instructions, the holder of such
Certificate shall be entitled to receive in exchange therefor, (i) with respect
to Certificates formerly representing Company Common Stock, a certificate
representing that number of whole shares of HCPI Common Stock which such holder
has the right to receive pursuant to the provisions of Section 2.7(a), (ii) with
respect to Certificates formerly representing Company Series B Preferred Stock,
a certificate representing that number of whole shares of HCPI Series C
Preferred Stock which such holder has the right to receive pursuant to Section
2.7(b), (iii) cash in lieu of any fractional shares of HCPI Common Stock to
which such holder is entitled pursuant to Section 2.9, after giving effect to
any required Tax withholdings, and (iv) any dividends or distributions to which
such holder is entitled pursuant to Section 2.10(e), and the Certificate so
surrendered shall forthwith be canceled. Until so surrendered and exchanged,
each Certificate shall represent the Merger Consideration into which the Company
Stock it theretofore represented shall have been converted pursuant to Sections
2.7(a) or (b), the right to receive certificates representing such Merger
Consideration and cash in lieu of any fractional shares pursuant to Section 2.9.
If the exchange of certificates representing shares of HCPI Common Stock or HCPI
Series C Preferred Stock is to be made to a Person other than the Person in
whose name the surrendered Certificate is registered, it shall be a condition of
exchange that the Certificate so surrendered shall be properly endorsed or shall
be otherwise in proper form for transfer and that the Person requesting such
exchange shall have paid any transfer and other Taxes required by reason of the
exchange of Certificates representing shares of HCPI Common Stock or HCPI Series
C Preferred Stock, as the case may be, to a Person other than the registered
holder of the Certificate surrendered or shall have established to the
satisfaction of the Surviving Corporation that such Tax either has been paid or
is not applicable.

     (c) At any time after the one-year anniversary of the Effective Time, HCPI
shall be entitled to require the Exchange Agent to deliver to HCPI all cash then
in the Fractional Securities Fund together with any other cash and any other
instruments (including shares of HCPI Common Stock and HCPI Preferred Series C
Preferred Stock) in its possession relating to


                                       18
<PAGE>


the transactions contemplated by this Agreement which had been made available to
the Exchange Agent and which have not been distributed to holders of
Certificates. Thereafter, each holder of a Certificate, subject to Section
2.7(c), may surrender such Certificate to the Surviving Corporation and (subject
to applicable abandoned property, escheat or other similar laws) receive in
exchange therefor the consideration payable in respect thereto pursuant to
Sections 2.7(a) or (b) and Section 2.9, without interest, but shall have no
greater rights against the Surviving Corporation than may be accorded to general
creditors of the Surviving Corporation under the MGCL. Notwithstanding the
foregoing, none of HCPI, the Surviving Corporation or the Exchange Agent shall
be liable to any Company Common Holder for shares of HCPI Common Stock (and any
cash payable in lieu of any fractional shares of HCPI Common Stock) or Company
Preferred Holder for shares of HCPI Series C Preferred Stock whose Certificates
have been delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law.

     (d) At the Effective Time, the stock transfer books of the Company shall be
closed and thereafter there shall be no further registration of transfers of
shares of Company Stock on the records of the Company. From and after the
Effective Time, the holders of Certificates evidencing ownership of shares of
Company Common Stock or shares of Company Series B Preferred Stock outstanding
immediately prior to the Effective Time shall cease to have any rights with
respect to such shares of Company Stock or Company Series B Preferred Stock, as
the case may be, except as otherwise provided for herein or by applicable law.

     (e) No dividends or other distributions declared or made after the
Effective Time with respect to shares of HCPI Common Stock or HCPI Series C
Preferred Stock shall be paid to the holder of any unsurrendered Certificate
with respect to the shares of HCPI Common Stock or HCPI Series C Preferred Stock
the holder is entitled to receive and no cash in lieu of fractional shares
pursuant to Section 2.9, shall be paid to such holder until the holder of such
Certificate shall surrender such Certificate in accordance with the provisions
of this Agreement. Upon such surrender, HCPI shall cause to be paid to the
Person in whose name the Certificates shall be issued, any dividends or
distributions with respect to such shares of HCPI Common Stock or HCPI Series C
Preferred Stock which have a record date after the Effective Time and shall have
become payable between the Effective Time and the time of such surrender. In no
event shall the Person entitled to receive such dividends or distributions be
entitled to receive interest thereon.

     (f) HCPI shall take all commercially reasonable action so that each holder
of Company Common Stock at the Effective Time which is converted into HCPI
Common Stock as set forth in Section 2.7(a) shall be entitled to vote on all
matters subject to the vote of holders of HCPI Common Stock with a record date
on or after the date of the Effective Time, whether or not such holder shall
have surrendered Certificates in accordance with the provisions of this
Agreement. For purposes of the immediate foregoing sentence, HCPI may rely
conclusively on the stockholder records of the Company in determining the
identity of and the number of shares of Company Common Stock held by each holder
of Company Common Stock at the Effective Time.

     (g) If, at any time after the Effective Time, the Surviving Corporation
shall consider or be advised that any deeds, bills of sale, assignments,
assurances or any other actions or things are necessary or desirable to vest,
perfect or confirm of record or otherwise in the Surviving Corporation its
right, title or interest in, to or under any of the rights or Assets of the
Company as a result of, or in connection with, the Merger or otherwise to carry
out this Agreement, the officers of the Surviving Corporation shall be
authorized to execute and deliver, in the name and on behalf the Company or
otherwise, all such deeds, bills of sale, assignments and assurances and to take
and do, in such names and on such behalves or otherwise, all such other actions
and things as may be necessary or desirable to vest, perfect or confirm any and
all right, title and interest in, to and under such rights or Assets in the
Surviving Corporation or otherwise to carry out the purposes of this Agreement.

     Section 2.11 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall
issue in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares of HCPI
Common Stock or HCPI Series C Preferred Stock, as applicable (and cash in lieu
of any fractional shares of HCPI Common Stock), and dividends or distributions
in respect thereof, if any, as may be required pursuant to Section 2.7(a),
Section 2.7(b), Section 2.9 and Section 2.10(e); provided, however, that HCPI
may, in its discretion and as a condition precedent to the issuance thereof,
require the owner of such lost, stolen or destroyed Certificates to deliver a
bond in such sum as it may reasonably direct as indemnity against any claim that
may be made against HCPI or the Exchange Agent with respect to the Certificates
alleged to have been lost, stolen or destroyed.

     Section 2.12 TAX CONSEQUENCES. It is intended by the Parties that the
Merger shall constitute a reorganization within the meaning of Section 368(a) of
the Code. The Parties hereby adopt this Agreement as a "plan of reorganization"
within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States
Treasury Regulations.

     Section 2.13 WITHHOLDING RIGHTS. HCPI or the Exchange Agent shall be
entitled to deduct and withhold from the Merger Consideration, or cash in lieu
of fractional shares, if any, otherwise payable pursuant to this Agreement to
any Company Common Holder or Company Preferred Holder such amounts as HCPI or
the Exchange Agent is required to deduct and withhold with respect to the making
of such payment under the Code or any provision of state, local, or foreign Tax
law. To the extent that amounts are so withheld by HCPI or the Exchange Agent,
such withheld amounts shall be treated for all purposes of this Agreement as
having been paid to the Company Common Holder or Company Preferred Holder, as
the case may be, in respect of which such deduction and withholding was made by
HCPI or the Exchange Agent. HCPI hereby agrees to comply with all requirements
of law, including any notice to the holders of Company Common Stock or Company
Series B Preferred Stock, as the case may be, in connection with such
withholding.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     The Company represents and warrants to HCPI that the statements contained
in this Article III are true and correct except as set forth herein or in the
disclosure schedule delivered by the Company to HCPI on or before the date of
this Agreement (the "Company Disclosure Schedule"). The Company Disclosure
Schedule shall be arranged in paragraphs corresponding to the numbered and
lettered paragraphs contained in this Agreement and the disclosure in any
paragraph shall qualify other paragraphs in this Agreement only to the extent
that such disclosure specifically references the fact that it also qualifies or
applies to such other specified paragraphs.

     Section 3.1 ORGANIZATION AND QUALIFICATION. The Company and each of its
Subsidiaries is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, with the corporate power and
authority to own and operate its business as presently conducted. The Company
and each of its Subsidiaries is duly qualified as a foreign corporation or other
entity to do business and is in good standing in each jurisdiction where the
ownership or operation of its properties or the nature of its activities makes
such qualification necessary, except for such failures of the Company and any of
its Subsidiaries to be so qualified as would not, when taken together with all
such other failures, cause a Company Material Adverse Effect. The Company has
previously made available to HCPI true and correct copies of its certificate of
incorporation and bylaws as currently in effect.

     Section 3.2 AUTHORIZATION; VALIDITY AND EFFECT OF AGREEMENT. The Company
has the requisite corporate power and authority to execute, deliver and perform
its obligations under this Agreement and to consummate the transactions
contemplated hereby subject to the adoption and approval of this Agreement by
the requisite vote of the holders of Company Common Stock. The execution and
delivery of this Agreement by the Company and the performance by the Company of
its obligations hereunder and the consummation of the transactions contemplated
hereby have been duly authorized by the Company Board and all other necessary
corporate action on the part of the Company, other than the adoption and
approval of this Agreement by the requisite vote of the holders of the Company
Common Stock, and no other corporate proceedings on the part of the Company are
necessary to authorize this Agreement and the transactions contemplated hereby.
This Agreement has been duly and validly executed and delivered by the Company
and constitutes a legal, valid and binding obligation of the Company,
enforceable against it in accordance with its terms, subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws of general applicability relating to or affecting creditors'

Company Stock Right currently outstanding was issued, the dates on which each
such outstanding and unvested Company Stock Right vests, the class and number of

Section 3.3(a) to the Company Disclosure Schedule, there are no securities,
options, warrants, calls, rights, commitments, agreements, arrangements or
undertakings of any kind to which the Company or any of its Subsidiaries is a

of the Company or the value of shares of Company Stock or any other capital
stock of the Company. There are no obligations, contingent or otherwise, of the
Company or any of its Subsidiaries to repurchase, redeem or otherwise acquire
any shares of Company Stock or any other capital stock of the Company or the

which it is bound, in each case, obligating the Company or any of its
Subsidiaries to issue, deliver or sell, or cause to be issued, delivered or
sold, additional shares of capital stock or other ownership interests (including

into any such option, warrant, equity security, call, right, commitment or
agreement; and (iii) there are no voting trusts, proxies or other voting
agreements or understandings currently in effect with respect to the shares of
capital stock of the Company to which the Company or any of its Subsidiaries is
currently a party or of which the Company has Knowledge. All shares of Company
Common Stock subject to issuance as specified in this Section 3.3(b) or in
Section 3.3(b) of the Company Disclosure Schedule are duly authorized and, upon
issuance on the terms and conditions specified in the instruments pursuant to
which they are issuable, shall be validly issued, fully paid and nonassessable.

     Section 3.4 SUBSIDIARIES. Other than Subsidiaries of Company formed or
acquired after the date hereof in accordance with the terms of Section 5.2 (of
which the Company has provided notice to HCPI prior to any such formation or
acquisition), Section 3.4 of the Company Disclosure Schedule sets forth all
Subsidiaries of the Company. All of the outstanding shares of capital stock
(including shares which may be issued upon exercise of outstanding options) or
other ownership interests of each of the Company's Subsidiaries are duly
authorized, validly issued, fully paid and nonassessable and all such shares and
ownership interests are owned by the Company or a Subsidiary of the Company free
and clear of all Liens. The Company owns, directly or indirectly, all of the
issued and outstanding capital stock and other ownership interests of each of
its Subsidiaries, free and clear of all Liens, and there are no existing
options, warrants, calls, subscriptions, convertible securities or other
securities, agreements, commitments or obligations of any character relating to
the outstanding capital stock or other securities of any Subsidiary of the
Company or which would require any Subsidiary of the Company to issue or sell
any shares of its capital stock, ownership interests or securities convertible
into or exchangeable for shares of its capital stock or ownership interests.

     Section 3.5 OTHER INTERESTS. Neither the Company nor any of the Company's
Subsidiaries owns or has the right or option to acquire, directly or indirectly,
any interest or investment in (whether equity or debt) any business or Person
(other than the Company's Subsidiaries and other than the rights held by the
Company or its Subsidiaries identified in Section 3.4 of the Company Disclosure
Schedule or as permitted, after the date hereof, under Section 5.2 (of which the
Company will have provided notice to HCPI prior to any such acquisition)).
Without limiting the generality of the foregoing sentence, neither the Company
nor any "Affiliate" or "Associate" (as such terms are defined in Section 3-601
of the MGCL) of the Company, is, or was at any time, the "Beneficial Owner" (as
defined in Section 3-601 of the MGCL), directly or indirectly, of 5% or more of
the voting power of the outstanding voting stock of HCPI. To the Knowledge of
the Company, no Person owns or has owned, actually or constructively (as such

Section 856(a)(6) of the Code or as set forth in Section 856(d)(5) of the Code)
in excess of 9.8% in value of the outstanding stock of the Company.

the execution, delivery and performance of this Agreement and the consummation
of the transactions contemplated hereby, except where the failure to obtain such
consent, approval, authorization, permit or declaration or to make such filing

Material Adverse Effect.

compliance with all foreign, federal, state and local laws and regulations
applicable to its operations or with respect to which compliance is a condition

Effect. Neither the Company nor any of its Subsidiaries has received any written
notice asserting a failure, or possible failure, to comply with any such law or
regulation, the subject of which written notice has not been resolved as
required thereby or

     (f) There are no Liens for Taxes upon any Assets of the Company or any

     (k) The Company (i) for all taxable years commencing with 1987 through the
most recent December 31, has been subject to taxation as a REIT and has
satisfied all requirements to qualify as a REIT for such years, (ii) has
operated in such a manner as to qualify as a REIT, and will continue to operate
through the Closing Date in such a manner as to qualify as a REIT, (iii) has not
taken or omitted to take any action which would reasonably be expected to result
in a challenge to its status as a REIT, and, to the Knowledge of the Company, no
such




                                       27

challenge is pending or threatened, and (iv) has not granted any exception to
its stock ownership limits set forth in its certificate of incorporation or
other governing document(s) relating to its tax status as a REIT. Each
Subsidiary of the Company that is a state law partnership or limited liability
company has been since its formation and continues to be treated for federal
income tax purposes as a partnership (or a disregarded entity) and not as a
corporation or an association or publicly traded partnership taxable as a
corporation. Each other Subsidiary of the Company has been since its formation,
and continues to be treated for federal income purposes as a "qualified REIT
subsidiary" as defined in Section 856(i) of the Code. Neither the Company nor
any Subsidiary of the Company holds any Asset the disposition of which would be
subject to rules similar to Section 1374 of the Code as a result of an election
under IRS Notice 88-19.

     Section 3.12 EMPLOYEE BENEFIT PLANS.

     (a) Section 3.12 of the Company Disclosure Schedule contains a complete
list of all Employee Plans of the Company and its Subsidiaries as of the date

Company and its Subsidiaries, including, without limitation, trust instruments,
if any, that form a part thereof, and all amendments thereto, have been
furnished or made available to HCPI and its counsel.

     (b) Each of the Employee Plans of the Company and its Subsidiaries (other
than any Multiemployer Plan) has been administered and is in substantial
compliance with the terms of such Employee Plan and all applicable laws, rules
and regulations. Each Pension Plan of the Company or its Subsidiaries which is
intended to be qualified under Section 401(a) of the Code has received a
favorable determination letter from the Internal Revenue Service with respect to
"TRA" (as defined in Section 1 of Rev. Proc. 93-39) (except with respect to the
amendment to the Company's Money Purchase Pension Plan referred to in Section
5.1(e)), and the Company is not aware of any circumstances likely to result in
revocation of any such favorable determination letter. All contributions
required to be made under the terms of any Employee Plan of the Company or its
Subsidiaries have been timely made or have been reflected in the consolidated
balance sheets included in or incorporated by reference in the Company SEC
Reports. Neither the Company nor any of its Subsidiaries has provided, or is
required to provide, security to any Pension Plan of the Company or its
Subsidiaries pursuant to Section 401(a)(29) of the Code.

     (c) No "reportable event" (as such term is used in Section 4043 of ERISA)
for which the notice requirements to the Pension Benefit Guaranty Corporation
have not been waived, or "accumulated funding deficiency" (as such term is used
in Section 412 of the Code or Section 302 of ERISA), whether or not waived, has
heretofore occurred with respect to any Pension Plan (other than any
Multiemployer Plan) of the Company or its Subsidiaries. Neither the Company nor
any of its Subsidiaries has engaged in a transaction in violation of Section 406
or 407 of ERISA or any transaction with respect to any Employee Plan that, in
either case, assuming the taxable period of such transaction expired as of the
date hereof, could subject the Company or any Subsidiary to a tax or penalty
imposed by either Section 4975 of the Code or Section 502(i) of ERISA in an
amount which would be material.


                                       28
<PAGE>


     (d) There is no material Action relating to or seeking benefits under any
Employee Plan of the Company or any of its Subsidiaries that is pending or, to
the Company's Knowledge, threatened against the Company, any of its
Subsidiaries, any of their ERISA Affiliates, or any of the Employee Plans of the
Company or any of its Subsidiaries, other than routine claims for benefits.

     (e) The Company has not incurred any withdrawal or other liability with
respect to any Multiemployer Plan of the Company or any of its Subsidiaries
under Title IV of ERISA which remains unsatisfied.

     (f) No liability under Subtitle C or D of Title IV of ERISA has been or is
expected to be incurred by the Company, any of its Subsidiaries or their ERISA
Affiliates with respect to any ongoing, frozen or terminated "single-employer
plan," within the meaning of Section 4001(a)(15) of ERISA, currently or formerly
maintained by any of them.

     (g) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will result in the
acceleration or creation of any rights of any current or former employee of the
Company or any of its Subsidiaries to benefits under any Employee Plan
(including, without limitation, the acceleration of the vesting or
exercisability of any stock options, the acceleration of the vesting of any
restricted stock, the acceleration of the accrual or vesting of any benefits
under any Pension Plan or the acceleration or creation of any rights under any
severance, parachute or change in control agreement).

     (h) Under each Pension Plan of the Company or its Subsidiaries which is a
single-employer plan, as of the last day of the most recent plan year ended
prior to the date hereof, the actuarially determined present value of all
"benefit liabilities," within the meaning of Section 4001(a)(16) of ERISA (as
determined on the basis of the actuarial assumptions contained in the Plan's
most recent actuarial valuation), did not exceed the then current value of the
assets of such Pension Plan, and there has been no material change in the
financial condition of such Pension Plan since the last day of the most recent
plan year.

     (i) Neither the Company nor any of its Subsidiaries has any obligations for
retiree health and life insurance benefits under any Employee Plan of the
Company or its Subsidiaries, except as required under Section 4980B of the Code
or Title I, Subtitle B, Part 6 of ERISA.

     Section 3.13 PROPERTIES.

     (a) Section 3.13(a) of the Company Disclosure Schedule lists all real
properties owned in fee simple by the Company and its Subsidiaries (the "Company

     (b) The Company and its Subsidiaries have fee simple title to the Company
Owned Property, and a valid leasehold interest in the Company Leased Property,

the Company Leased Property, as appropriate, in an amount at least equal to the
original purchase price thereof, subject only to the matters disclosed in
Sections 3.13(a), (b) and (c) above together with the corresponding provisions
of the Company Disclosure Schedule, and, to the Knowledge of the Company, such
policies are, at the date hereof, in full force and effect and no material claim
has been made against any such policy.

     (e) To the Knowledge of the Company all (i) certificates, permits or
licenses from any Governmental Entity having jurisdiction over any Company Real
Property and (ii) agreements, easements or other rights, necessary to permit the
lawful use and operation of the buildings and improvements on any of the Company
Real Property have been obtained and are in full force and effect, except where
the failure to maintain the same would not cause a Company Material Adverse
Effect, and the Company does not have any Knowledge of any pending threat or
modification or cancellation of the same. No Company Real Property is located
outside of the United States and neither the Company nor any of its Subsidiaries
conducts its business of owning, leasing or operating properties outside of the
United States. All work to be performed, payments to be made and actions to be
taken by the Company or its Subsidiaries prior to the date hereof pursuant to

such case, which is, individually or in the aggregate, material to the Company
and its Subsidiaries taken as a whole.

     (f) The Company has not received any written notice or written notices of
any violation of any federal, state or municipal law, ordinance, order,
regulation or requirement affecting any portion of any Company Real Property
issued by any Governmental Entity except for such notice or notices which would
not have, individually or in the aggregate, a Company Material Adverse Effect.
Neither the Company nor any of its Subsidiaries has received any written notice
to the effect that any condemnation or rezoning proceedings are pending or
threatened with respect to any Company Real Property, except where any such
written notice of such a proceeding would not, individually or in the aggregate,
cause a Company Material Adverse Effect.


                                       30
<PAGE>


     (g) Except as would not, individually or in the aggregate, cause a Company
Material Adverse Effect, there is no (i) material structural defect relating to
the Company Real Property, (ii) Company Real Property whose building systems are
not in working order in any material respect or (iii) physical damage to any
Company Real Property in excess of $100,000 or current renovation or restoration

there is no insurance in effect covering the cost of such damage, renovation or
restoration, except for the payment by the Company of a deductible under the
applicable insurance policy.

     (h) Each copy of any Company Lease which has been delivered to, or made
available for review by, HCPI as of the date hereof has been a true and correct
copy of such Company Lease as amended to date. True and correct copies of all
other Company Leases, as amended, will be delivered to, or made available for

     Company Leases relating to multi-tenant medical office space); and

          (iv) the amount of periodic fixed rentals due under the Company Lease.

     (i) All regularly scheduled rent payments due under each Company Lease have
been paid during the period March 31, 1999 through the date hereof, and to the
Company's Knowledge, no lessee is in material default, and no condition or event
exists which with the giving of notice or the passage of time, or both, would
constitute a material default by any lessee or contracting party, under any
Company Lease.

     (j) The Company Leases are in full force and effect except where the
failure of the foregoing to be true would not have a material affect on the
ability of the Company and its Subsidiaries, taken as a whole, to operate their
businesses. None of the Company nor any of its Subsidiaries is in material
default under any Company Lease, and, to the Knowledge of the Company, no
material defaults (unless subsequently cured) by the Company or its Subsidiaries
have been alleged thereunder.

under any of the Company Contracts, except if such breach, violation or default

constitute a material breach, violation or default, or give rise to a right of
termination, modification, cancellation, foreclosure, imposition of a Lien,
prepayment or acceleration under any of the Company Contracts, which breach,
violation, default or other occurrence referred to in clauses (ii) or (iii),
individually or in the aggregate with other such breaches, violations, defaults

Material Adverse Effect.

hereof, acquisitions of real property in the ordinary course of business, and
Persons owning real property, in the ordinary course of business (of which HCPI

9.9% in value of the outstanding stock of HCPI.

     Section 4.6 NO CONFLICT; REQUIRED FILINGS AND CONSENTS.

     (a) Neither the execution and delivery of this Agreement nor the

transactions contemplated hereby, will: (i) conflict with HCPI's charter or

<PAGE>


Subsidiaries to purchase or repurchase any notes, bonds or instruments of any
kind except, in the case of clauses (ii) and (iii), for such violations,
breaches, conflicts, defaults or other occurrences which, individually or in the
aggregate, would not cause a HCPI Material Adverse Effect.

the Securities Act, and Blue Sky Laws, (ii) for the filing of the Certificate of
Merger pursuant to the DGCL and the filing of the Articles of Merger pursuant to

execution, delivery and performance of this Agreement and the consummation of
the transactions contemplated hereby, except where the failure to obtain such
consent, approval, authorization, permit or declaration or to make such filing
or registration would not, individually or in the aggregate, cause a HCPI
Material Adverse Effect.

with all foreign, federal, state and local laws and regulations applicable to
its operations or with respect to which compliance is a condition of engaging in
the business thereof, except to the extent that failure to comply would not,
individually or in the aggregate, cause a HCPI Material Adverse Effect. Neither
HCPI nor any of its Subsidiaries has received any written notice asserting a
failure, or possible failure, to comply with any such law or regulation, the
subject of which written notice has not been resolved as required thereby or
otherwise to the satisfaction of the party sending the notice, except for such
failure as would not, individually or in the aggregate, cause a HCPI Material
Adverse Effect.

     (a) HCPI has filed with the SEC and made available to the Company true and
complete copies of each registration statement, proxy or information statement,
form, report and other document required to be filed by HCPI or any of its

     (b) Each of the consolidated balance sheets included in or incorporated by
reference into HCPI SEC Reports (including the related notes and schedules)

all material respects, the consolidated financial position of HCPI and its
consolidated Subsidiaries as of its date, and each of the consolidated
statements of income, retained earnings and cash flows of HCPI included in or
incorporated by reference into HCPI SEC Reports (including any related notes and
schedules) presents fairly, in all material respects, the results of operations,
retained earnings or cash flows, as the case may be, of HCPI and its
Subsidiaries for the periods set forth therein (subject, in the case of
unaudited statements, to normal year-end audit adjustments), in each case in
accordance with GAAP consistently applied during the periods involved, except as
may be noted therein.

     (c) Except as set forth in the HCPI SEC Reports, neither HCPI nor any of
its Subsidiaries has any liabilities or obligations of any nature (whether
accrued, absolute, contingent or otherwise) that would be required to be
reflected on, or reserved against in, a balance sheet of HCPI or in the notes

liabilities or obligations that were so reserved on, or reflected in (including
the notes to), the consolidated balance sheet of HCPI as of March 31, 1999, (ii)
liabilities or obligations arising in the ordinary course of business (including
trade indebtedness and liabilities, obligations and secured debt assumed in
connection with the acquisition of properties by HCPI or its Subsidiaries) since
March 31, 1999, and (iii) liabilities or obligations which would not,
individually or in the aggregate, cause a HCPI Material Adverse Effect.

     Section 4.9 ABSENCE OF CERTAIN CHANGES. Except as set forth in the HCPI SEC
Reports and except for the transactions expressly contemplated hereby, since
March 31, 1999, HCPI and its Subsidiaries have conducted their respective
businesses only in the ordinary and usual course consistent with past practices
(including the incurrence of trade indebtedness and liabilities, obligations and
secured debt assumed in connection with the acquisition of properties by HCPI or
its Subsidiaries) and there has not been any change in HCPI's business,
operations, condition (financial or otherwise), results of operations, Assets or
liabilities, except for changes expressly contemplated hereby or changes which,
individually or in the aggregate, have not caused or will not cause a HCPI
Material Adverse Effect.

     Section 4.10 LITIGATION. Except as set forth in the HCPI SEC Reports, there
is no Action instituted, pending or, to the Knowledge of HCPI, threatened, in
each case against HCPI, any of its Subsidiaries or any of their respective
Assets which, individually or in the aggregate, directly or indirectly, would
have a HCPI Material Adverse Effect, nor is there any outstanding judgment,
decree or injunction, in each case against HCPI, any of its Subsidiaries or any
of their respective Assets, or any statute, rule or order of any Governmental
Entity applicable to HCPI or any of its Subsidiaries which, individually or in
the aggregate, has caused, or would cause, a HCPI Material Adverse Effect.

     Section 4.11 TAXES.

     (a) HCPI and its Subsidiaries have (i) duly filed (or there have been filed
on their behalf) or have duly filed for an appropriate extension, with the
appropriate Governmental Entities all Tax Returns required to be filed by them
and such Tax Returns are true, correct and complete in all material respects,
and (ii) duly paid in full all Taxes required to have been paid by


                                       39
<PAGE>


them, whether or not shown to be due on such Tax Returns, provided, however, to
the extent the foregoing clauses (i) or (ii) relate to Taxes for which a tenant
is responsible pursuant to a HCPI Lease, to the Knowledge of HCPI, such clauses
(i) and (ii) are true with respect to such tenant;

     (b) No written claim is pending by an authority in a jurisdiction where any

federal or state, local or foreign audits or other administrative proceedings or
court proceedings are presently pending with regard to any Taxes or Tax Returns
of HCPI or its Subsidiaries, and neither HCPI nor any of its Subsidiaries has
received a written notice of any threatened audits with respect to Taxes or Tax
Returns of HCPI or any of its Subsidiaries, and neither HCPI nor any of its
Subsidiaries has waived any statute of limitations with respect to Taxes or
agreed to any extension of time with respect to a Tax assessment or deficiency;

     (d) Section 4.11(d) of the HCPI Disclosure Schedule sets forth , with
respect to those taxable years for which Tax Returns have not yet been filed,
the taxable years of HCPI and its Subsidiaries as to which extensions to file
Tax Returns have been requested or any waiver of the applicable statute of
limitations has been executed;

     (e) The Internal Revenue Service has not asserted against HCPI or any of
its Subsidiaries any deficiency or claim for Taxes with respect to HCPI's
taxable years beginning on or after January 1, 1990, and no other taxing
authority (whether domestic or foreign) has asserted against HCPI or any of its
Subsidiaries any deficiency or claim for Taxes in excess of $100,000 for any of
HCPI's taxable years beginning on or after January 1, 1990;

     (f) There are no Liens for Taxes upon any Assets of HCPI or any Subsidiary
thereof, except for Liens for Taxes not yet due or delinquent or for which a
tenant is responsible under a lease for real property. With respect to any such
Taxes for which a tenant is responsible, to the Knowledge of HCPI no such Taxes
are delinquent. No written power of attorney that has been granted by HCPI or
any of its Subsidiaries (other than to HCPI or a Subsidiary) currently is in
force with respect to any matter relating to Taxes;

     (g) Neither HCPI nor any of its Subsidiaries has, with regard to any Assets
held by any of them, agreed to have Section 341(f)(2) of the Code apply to any
disposition of a "subsection (f) asset" (as such term is defined in Section
341(f)(4) of the Code) owned by HCPI or any of its Subsidiaries;

     (h) None of HCPI and its Subsidiaries is a party to any Tax allocation or

Taxes of any Person (other than any of HCPI


                                       40
<PAGE>


and its Subsidiaries) under Treasury Regulation Section 1.1502-6 (or any similar
provision of state, local, or foreign law), as a transferee or successor, by
contract, or otherwise;

     (j) Since HCPI's taxable year ending December 31, 1985, HCPI has not
incurred and does not expect to incur through the Closing Date any liability for
Taxes under Section 857(b), 860(c) or 4981 of the Code, and neither HCPI nor any
of its Subsidiaries has incurred any material liability for Taxes other than in
the ordinary course of business. To the Knowledge of HCPI, no event has occurred
and no condition or circumstance exists which presents a material risk that any
material Tax described in the preceding sentence will be imposed upon HCPI.

     (k) HCPI (i) for all taxable years commencing with 1985 through the most
recent December 31, has been subject to taxation as a REIT and has satisfied all
requirements to qualify as a REIT for such years, (ii) has operated in such a
manner as to qualify as a REIT, and will continue to operate through the Closing
Date in such a manner as to qualify as a REIT, (iii) has not taken or omitted to
take any action which would reasonably be expected to result in a challenge to
its status as a REIT, and, to the Knowledge of HCPI, no such challenge is
pending or threatened, and (iv) has not granted any exception to its stock
ownership limits set forth in its charter or other governing document(s)
relating to its tax status as a REIT. Each Subsidiary of HCPI that is a state
law partnership or limited liability company has been since its formation and
continues to be treated for federal income tax purposes as a partnership (or a
disregarded entity) and not as a corporation or an association or publicly
traded partnership taxable as a corporation. Each other Subsidiary of HCPI has
been since its formation, and continues to be treated for federal income Tax
purposes as a "qualified REIT subsidiary" as defined in Section 856(i) of the
Code. Neither HCPI nor any Subsidiary of HCPI holds any Asset the disposition of
which would be subject to rules similar to Section 1374 of the Code as a result
of an election under IRS Notice 88-19.

     Section 4.12 EMPLOYEE BENEFIT PLANS.

     (a) Section 4.12 of the HCPI Disclosure Schedule contains a complete list
of all Employee Plans of HCPI and its Subsidiaries as of the date hereof. True
and complete copies or descriptions of the Employee Plans of HCPI and its
Subsidiaries, including, without limitation, trust instruments, if any, that
form a part thereof, and all amendments thereto, have been furnished or made
available to the Company and its counsel.

     (b) Each of the Employee Plans of HCPI and its Subsidiaries (other than any
Multiemployer Plan) has been administered and is in substantial compliance with
the terms of such Employee Plan and all applicable laws, rules and regulations.
Each Pension Plan of HCPI or its Subsidiaries which is intended to be qualified
under Section 401(a) of the Code has received a favorable determination letter
from the Internal Revenue Service with respect to "TRA" (as defined in Section 1
of Rev. Proc. 93-39), and HCPI is not aware of any circumstances likely to
result in revocation of any such favorable determination letter. All
contributions required to be made under the terms of any Employee Plan of HCPI
or its Subsidiaries have been timely made or have been reflected in the
consolidated balance sheets


                                       41
<PAGE>


included in or incorporated by reference in the HCPI SEC Reports. Neither HCPI
nor any of its Subsidiaries has provided, or is required to provide, security to
any Pension Plan of HCPI or its Subsidiaries pursuant to Section 401(a)(29) of
the Code.

     (c) No "reportable event" (as such term is used in Section 4043 of ERISA)
for which the notice requirements to the Pension Benefit Guaranty Corporation
have not been waived, or "accumulated funding deficiency" (as such term is used
in section 412 of the Code or Section 302 of ERISA), whether or not waived, has
heretofore occurred with respect to any Pension Plan (other than any
Multiemployer Plan) of HCPI or its Subsidiaries. Neither HCPI nor any of its
Subsidiaries has engaged in a transaction in violation of Section 406 or 407 of
ERISA or any transaction with respect to any Employee Plan that, in either case,
assuming the taxable period of such transaction expired as of the date hereof,
could subject HCPI or any Subsidiary to a tax or penalty imposed by either
Section 4975 of the Code or Section 502(i) of ERISA in an amount which would be
material.

     (d) There is no material Action relating to or seeking benefits under any
Employee Plan of HCPI or any of its Subsidiaries that is pending or, to HCPI's
Knowledge, threatened against HCPI, any of its Subsidiaries, any of their ERISA
Affiliates, or any of the Employee Plans of HCPI or any of its Subsidiaries,
other than routine claims for benefits.

     (e) HCPI has not incurred any withdrawal or other liability with respect to
any Multiemployer Plan of HCPI or any of its Subsidiaries under Title IV of
ERISA which remains unsatisfied.

     (f) No liability under Subtitle C or D of Title IV of ERISA has been or is
expected to be incurred by HCPI, any of its Subsidiaries or their ERISA
Affiliates with respect to any ongoing, frozen or terminated "single-employer
plan," within the meaning of Section 4001(a)(15) of ERISA, currently or formerly
maintained by any of them.

     (g) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will result in the
acceleration or creation of any rights of any current or former employee of HCPI
or any of its Subsidiaries to benefits under any Employee Plan (including,
without limitation, the acceleration of the vesting or exercisability of any
stock options, the acceleration of the vesting of any restricted stock, the
acceleration of the accrual or vesting of any benefits under any Pension Plan or
the acceleration or creation of any rights under any severance, parachute or
change in control agreement).

     (h) Under each Pension Plan of HCPI or its Subsidiaries which is a
single-employer plan, as of the last day of the most recent plan year ended
prior to the date hereof, the actuarially determined present value of all
"benefit liabilities," within the meaning of Section 4001(a)(16) of ERISA (as
determined on the basis of the actuarial assumptions contained in the Plan's
most recent actuarial valuation), did not exceed the then current value of the
assets of such Pension Plan, and there has been no material change in the
financial condition of such Pension Plan since the last day of the most recent
plan year.

     (i) Neither HCPI nor any of its Subsidiaries has an obligations for retiree
health and life insurance benefits under any Employee Plan of HCPI or its
Subsidiaries, except as required under Section 4980B of the Code of Title I,
Subtitle B, Part 6 of ERISA.

     Section 4.13 PROPERTIES.

     (a) Section 4.13(a) of the HCPI Disclosure Schedule lists all real
properties owned in fee simple by HCPI and its Subsidiaries (the "HCPI Owned
Property") and all real properties leased by HCPI and its Subsidiaries as lessee
(the "HCPI Leased Property"), which are all of the real properties owned or
leased by them. The HCPI Owned Property and the HCPI Leased Property is referred
to herein collectively as the "HCPI Real Property."

     (b) HCPI and its Subsidiaries have fee simple title to the HCPI Owned
Property, and a valid leasehold interest in the HCPI Leased Property, sufficient
to allow HCPI and its Subsidiaries, taken as a whole, to conduct its business of
leasing properties to third parties as currently conducted. The HCPI Real
Property is not subject to any Encumbrances, except for any Permitted
Encumbrances.

     (c) Except as set forth on Section 4.14(a) of the HCPI Disclosure Schedule
or as disclosed in the HCPI SEC Reports, the HCPI Real Property is not
encumbered by any material debt.

     (d) Valid policies of title insurance have been issued insuring HCPI's or
its applicable Subsidiary's fee simple title to the HCPI Owned Property or
HCPI's or its applicable Subsidiary's leasehold interest in the HCPI Leased
Property, as appropriate, in an amount at least equal to the original purchase
price thereof, subject only to the matters disclosed in Sections 4.13(a), (b)
and (c) above together with the corresponding provisions of the HCPI Disclosure
Schedule, and, to the Knowledge of HCPI, such policies are, at the date hereof,
in full force and effect and no material claim has been made against any such
policy.

     (e) To the Knowledge of HCPI all (i) certificates, permits or licenses from
any Governmental Entity having jurisdiction over any HCPI Real Property and (ii)
agreements, easements or other rights, necessary to permit the lawful use and
operation of the buildings and improvements on any of the HCPI Real Property
have been obtained and are in full force and effect, except where the failure to
maintain the same would not cause a HCPI Material Adverse Effect and HCPI does
not have any Knowledge of any pending threat or modification or cancellation of
the same. No HCPI Real Property is located outside of the United States and
neither HCPI nor any of its Subsidiaries conducts its business of owning,
leasing or operating properties outside of the United States. All work to be
performed, payments to be made and actions to be taken by HCPI or its
Subsidiaries prior to the date hereof pursuant to any agreement entered into
with a Governmental Entity in connection with a site approval, zoning
reclassification or other similar action relating to a HCPI Real Property has
been performed, paid or taken, as the case may be, and HCPI has no Knowledge of
any planned or proposed work, payments or actions that may be required after the
date hereof pursuant to such agreements in each such case, which is,
individually or in the aggregate, material to HCPI and its Subsidiaries taken as
a whole.


                                       43

     (f) HCPI has not received any written notice or written notices of any
violation of any federal, state or municipal law, ordinance, order, regulation
or requirement affecting any portion of any HCPI Real Property issued by any
Governmental Entity except for such notice or notices which would not have,
individually or in the aggregate, a HCPI Material Adverse Effect. Neither HCPI
nor any of its Subsidiaries has received any written notice to the effect that
any condemnation or rezoning proceedings are pending or threatened with respect
to any HCPI Real Property, except where any such written notice of such a
proceeding would not, individually or in the aggregate, cause a HCPI Material
Adverse Effect.

     (g) Except as would not, individually or in the aggregate, cause a HCPI
Material Adverse Effect, there is no (i) material structural defect relating to
the HCPI Real Property, (ii) HCPI Real Property whose building systems are not
in working order in any material respect or (iii) physical damage to any HCPI
Real Property in excess of $100,000 or current renovation or restoration to any
HCPI Real Property the remaining cost of which exceeds $100,000 for which there
is no insurance in effect covering the cost of such damage, renovation or
restoration except for the payment by HCPI of a deductible under the applicable
insurance policy.

     (h) Each copy of any HCPI Lease which has been delivered to, or made
available for review by, the Company as of the date hereof has been a true and
correct copy of such HCPI Lease as amended to date. True and correct copies of
all other HCPI Leases, as amended, will be delivered to, or made available for
review by, the Company reasonably promptly after the date hereof. Section
4.13(h) of the HCPI Disclosure Schedule lists the following information with
respect to each HCPI Lease that covers more than 7,500 square feet of space:

          (i) the name of the lessee;

          (ii) the expiration date;

         (iii) the term of any options by the lessee to renew (exclusive of any
     HCPI's Leases relating to multi-tenant medical office space); and

          (iv) the amount of periodic fixed rentals due under the HCPI Lease.

     (i) All regularly scheduled rent payments due under each HCPI Lease have
been paid during the period March 31, 1999 through the date hereof, and to
HCPI's Knowledge, no lessee is in material default, and no condition or event
exists which with the giving of notice or the passage of time, or both, would
constitute a material default by any lessee or contracting party, under any HCPI
Lease.

     (j) The HCPI Leases are in full force and effect, except where the failure
of the foregoing to be true would not have a material effect on the ability of
HCPI and its Subsidiaries, taken as a whole, to operate their businesses. None
of HCPI nor any of its Subsidiaries is in material default under any HCPI Lease,
and, to the Knowledge of HCPI, no


                                       44
<PAGE>


material defaults (unless subsequently cured) by HCPI or its Subsidiaries have
been alleged thereunder.

     Section 4.14 CONTRACTS.

     (a) Section 4.14(a) of HCPI Disclosure Schedule contains a complete and
accurate list of all HCPI Contracts, other than the HCPI Contracts which have
been filed as an exhibit to the HCPI SEC Reports. Each copy of a HCPI Contract
which has been delivered to, or made available for review by, the Company is a
true and correct copy of such HCPI Contract as amended to date.

     (b) As of the date of this Agreement, (i) each of the HCPI Contracts is
valid and binding upon HCPI or the applicable Subsidiary of HCPI in accordance
with its terms and is in full force and effect, subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws of general applicability relating to or affecting creditors'
rights generally or general equitable principles (whether considered in a
proceeding in equity or at law), (ii) there is no material breach or violation
of or default by HCPI or any of its Subsidiaries under any of the HCPI
Contracts, except if such breach, violation or default has been waived, and
(iii) no event has occurred with respect to HCPI or any of its Subsidiaries
which, with notice or lapse of time or both, would constitute a material breach,
violation or default, or give rise to a right of termination, modification,
cancellation, foreclosure, imposition of a Lien, prepayment or acceleration
under any of the HCPI Contracts, which breach, violation, default or other
occurrence referred to in clauses (ii) or (iii), individually or in the
aggregate with other such breaches, violations, defaults or other occurrences
referred to in clauses (ii) or (iii), would cause a HCPI Material Adverse
Effect.

     Section 4.15 LABOR RELATIONS. Except as would not cause a HCPI Material
Adverse Effect, (i) there are no controversies pending or, to the Knowledge of
HCPI, threatened between HCPI or any of its Subsidiaries and any of their
respective employees; (ii) neither HCPI nor any of its Subsidiaries is a party,

good title to, or is validly licensed to use, all of the Intellectual Property
material to the business of HCPI and its Subsidiaries, taken as a whole, free of
all material Liens. The consummation of the Merger will not result in the loss
of any rights by HCPI or any of its Subsidiaries in any Intellectual Property
that is material to the businesses of HCPI and its Subsidiaries, taken as a
whole.

     Section 4.17 ENVIRONMENTAL MATTERS. Except as set forth in the HCPI SEC
Reports, and except, individually or in the aggregate, as has not had, and would
not cause, a HCPI Material Adverse Effect, HCPI, each of its Subsidiaries and,
to the Knowledge of HCPI,


                                       45

against HCPI or any of its Subsidiaries based on or resulting from the
manufacture, processing, use, treatment, storage, disposal, transport, or
handling, or the emission, discharge or release into the environment, of any
Hazardous Material; and (d) have taken all actions required under applicable
Environmental Laws to register any products or materials required to be
registered by HCPI or its Subsidiaries thereunder. This Section 4.17 constitutes
the sole representation of HCPI concerning any Environmental Law or Hazardous
Substance.

     Section 4.18 OPINION OF FINANCIAL ADVISOR. HCPI has received the opinion of
Merrill Lynch & Co., Inc., (the "HCPI Financial Advisor"), as of the date of
this Agreement, to the effect that the consideration to be paid by HCPI in
connection with the Merger is fair to HCPI from a financial point of view. As of
the date of the filing of the Joint Proxy Statement/Prospectus with the SEC, and
as of the date of the effectiveness of the Registration Statement, HCPI will
have been authorized by the HCPI Financial Advisor to permit, subject to prior
review and consent by such HCPI Financial Advisor, the inclusion of such
fairness opinion (or a reference thereto) in the Joint Proxy
Statement/Prospectus and in the Registration Statement, respectively.

     Section 4.19 BROKERS. No broker, finder or investment banker (other than
the HCPI Financial Advisor the fees and expenses of which shall be paid by HCPI)
is entitled to any brokerage, finder's or other fee or commission in connection
with the Merger or the transactions contemplated by this Agreement based upon
arrangements made by or on behalf of HCPI or any of its subsidiaries. HCPI has
heretofore furnished to the Company a complete and correct copy of all
agreements between HCPI and the HCPI Financial Advisor pursuant to which such
firm would be entitled to any such payment.

     Section 4.20 VOTE REQUIRED. The affirmative vote of the holders of
two-thirds of the outstanding shares of HCPI Common Stock entitled to vote
thereon is the only vote of the holders of any class or series of HCPI's capital
stock necessary to approve the Merger. The HCPI Board, at a meeting duly called

contemplated hereby, including the Merger, are in the best interests of HCPI,
(b) approved this Agreement and the transactions contemplated hereby, including
the Merger, (c) declared that the Merger is advisable on the terms and

     Section 4.21 ACCOUNTING AND TAX MATTERS. None of HCPI, its Subsidiaries,
directors, officers or agents, has taken or agreed to take any action, nor does
any executive officer know of any circumstances, that (without regard to any
action taken or agreed to be taken by the Company or any of its Affiliates)
would prevent the Merger from qualifying as a reorganization within the meaning
of Section 368(a) of the Code.

     Section 4.22 INSURANCE. All fire and casualty, general liability, business
interruption, product liability, and sprinkler and water damage insurance
policies maintained by HCPI or any of its Subsidiaries with coverage of loss
payouts in excess of $15,000,000 are with reputable insurance carriers, provide
full and adequate coverage for all normal risks incident to the business of HCPI
and its Subsidiaries and their respective Assets, and are in character and
amount at least equivalent to that carried by Persons engaged in similar
businesses and substantially equivalent to that carried by Persons engaged in
similar businesses and subject to the same or similar perils or hazards except
for any such failures to carry or maintain insurance policies that, individually
or in the aggregate, would not cause a HCPI Material Adverse Effect.

     Section 4.23 TAKEOVER PROVISIONS INAPPLICABLE. HCPI has taken all action
necessary, if any, to exempt the transactions contemplated by this Agreement
from the operation of any "fair price," "moratorium," "control share
acquisition" or any other anti-takeover statute enacted under the laws of the
State of Maryland.

     Section 4.24 NO MATERIAL ADVERSE EFFECT. Except as disclosed in the HCPI
SEC Reports, to the Knowledge of HCPI, no current fact alone or together with
another current fact would cause a HCPI Material Adverse Effect.

     Section 4.25 RIGHTS PLAN. Other than as Merger Consideration pursuant to
this Agreement, the entering into of this Agreement and the consummation of the
transactions contemplated hereby do not and will not result in the grant of any
rights to any Person under the HCPI Rights Plan or enable or require the HCPI
Rights to be exercised, distributed or triggered and there has been no event
which has enabled or required the HCPI Rights to be exercised, distributed or
triggered.

     Section 4.26 OWNERSHIP OF COMPANY COMMON STOCK. To the Knowledge of HCPI,
none of HCPI or any of its Affiliates, is the Beneficial Owner or record owner
of any shares of Company Stock, other than HCPI's ownership of approximately
52,900 shares of Company Common Stock and such securities, if any, held by, or
for the account of employees or former employees of, HCPI or any of its
Affiliates.

     Section 5.3 CONDUCT OF BUSINESS OF HCPI PENDING THE MERGER. During the
period from the date of this Agreement and continuing until the earlier of the
termination of this Agreement or the Effective Time, HCPI agrees as to itself
and each of its Subsidiaries (except to the extent that the Company shall
otherwise consent in writing or as expressly contemplated in this Agreement) to
carry on its business in the ordinary course in substantially the same manner as
previously conducted, to pay its debts and Taxes when due, subject to good faith
disputes over such debts or Taxes, in the ordinary course in substantially the
same manner as previously paid, to pay or perform its other material obligations
when due in the ordinary course in substantially the same manner as previously
paid or performed, to maintain insurance coverages and its books, accounts and
records in the usual manner consistent with past practices, to comply in all
material respects with all applicable laws, ordinances and regulations of
Governmental Entities, to maintain and keep its properties and equipment in good
repair, working order and condition (except ordinary wear and tear), and, to the
extent consistent with such business, use all reasonable efforts consistent with
past practices and policies to preserve intact its present business
organization, and preserve its relationships with officers, employees and
customers, suppliers, distributors, and others having business dealings with it.
Without limiting the generality of the foregoing and except as expressly
contemplated by this Agreement or in the HCPI Disclosure Schedule, during the
period from the date of this Agreement and continuing until the earlier of the
termination of this Agreement or the Effective Time, without the written consent
of the Company, HCPI shall not and shall not permit any of its Subsidiaries to:

     (a) except for the adoption of articles supplementary relating to the HCPI
Series C Preferred Stock in the form attached hereto as Exhibit B, adopt or
propose any amendment to (i) its charter or comparable charter or organizational
documents or (ii) the HCPI Rights Plan;

     (b) except as set forth in and subject to Sections 5.4 and 5.5, declare,
set aside or pay any dividend or make any other distribution or payment with
respect to any shares of its capital stock (including any dividend distribution
payable in, or otherwise make a distribution of, shares of capital stock of any
existing or subsequently formed Subsidiary of HCPI), except (i) any regular
quarterly dividend or distribution paid by HCPI or any of its Subsidiaries on
capital stock or other equity interests in the ordinary course of business,
consistent with past practices (including any increases in such dividends as are
consistent with HCPI's past practice of increasing dividends) or (ii) dividends
or distributions to HCPI or one of its Subsidiaries;

     (c) split (including reverse split), combine, subdivide, reclassify or
redeem, purchase or otherwise acquire, or propose to redeem or purchase or
otherwise acquire, any shares of its capital stock, or any of its other

     Section 5.4 CONTINUED QUALIFICATION AS A REAL ESTATE INVESTMENT TRUST;
FINAL COMPANY DIVIDEND. From and after the date hereof through the Effective
Time, each of


                                       53
<PAGE>


Company and HCPI will maintain its respective qualification as a "real estate
investment trust" under the Code and the rules and regulations thereunder.
Without limiting the generality of the foregoing, if necessary to enable the
Company to make aggregate dividend distributions during its final taxable period
equal to the Minimum Distribution Dividend, Company shall declare and pay a
dividend (the "Final Company Dividend") to holders of Company Common Stock in an
amount equal to the minimum dividend sufficient to permit Company to make
aggregate dividend distributions during its final taxable period equal to the
Minimum Distribution Dividend. If Company determines it is necessary to declare
the Final Company Dividend, it shall notify HCPI at least ten days prior to the
date for the Company Stockholder Meeting so that HCPI may, at its option,
declare and pay a dividend per share to holders of HCPI Common Stock in an
amount per share equal to the quotient obtained by dividing (x) the Final
Company Dividend per share of Company Common Stock by (y) the Exchange Ratio.
For purposes of this paragraph, the term "Minimum Distribution Dividend" shall
mean a distribution with respect to Company's taxable year ending at the
Effective Time which is sufficient to allow Company to (i) satisfy the
distribution requirements set forth in Section 857(a) of the Code, and (ii)
avoid, to the extent possible, the imposition of income tax under Section 857(b)
of the Code and the imposition of excise tax under Section 4981 of the Code.

     Section 5.5 DIVIDEND PAYMENT COORDINATION. Each of HCPI and Company shall
coordinate with the other the declaration of any dividends in respect of HCPI
Common Stock and Company Common Stock and the record and payment dates therefor,
it being the intention of the Parties that holders of Company Common Stock shall
not receive (i) dividends for any period with respect to both shares of Company
Common Stock and shares of HCPI Common Stock received in exchange therefor in
connection with the Merger or (ii) fail to receive dividends for any period on
shares of Company Common Stock or shares of HCPI Common Stock received in
exchange therefor in connection with the Merger.

respect to the transactions contemplated hereby (subject to the right of the
Company Board to withdraw, amend or modify such recommendation in accordance
with Section 6.3) may be included in the Registration Statement and the Joint
Proxy Statement/Prospectus. HCPI hereby agrees that the recommendation of HCPI
Board described in Section 4.20 may be included in the Registration Statement
and the Joint Proxy Statement/Prospectus. HCPI shall use its commercially
reasonable best efforts to take all actions required under any applicable
federal or state securities or Blue Sky Laws in connection with the issuance of

incident thereto. As promptly as practicable after the Registration Statement
becomes effective, the Company and HCPI shall cause the Joint Proxy
Statement/Prospectus to be mailed to their respective stockholders.

     (b) The Company and HCPI each agrees that none of the information supplied
by it or its Subsidiaries to be included or incorporated by reference in the
Joint Proxy Statement/Prospectus or any amendment thereof or supplement thereto,
will, on the date of the mailing of the Joint Proxy Statement/Prospectus or any
amendment or supplement thereto, and at the time of the Company Stockholder
Meeting and the HCPI Stockholder Meeting, 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. The Company and HCPI
each agrees that none of the information supplied by it or its Subsidiaries to
be included or incorporated by reference in the Registration Statement will, at
the time the Registration Statement becomes effective under the Securities Act,
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.

     (c) Without limiting the generality of the foregoing, prior to the
Effective Time (i) the Company and HCPI shall notify each other as promptly as
practicable upon becoming aware of any event or circumstance which should be
described in an amendment of, or supplement to, the Joint Proxy
Statement/Prospectus or the Registration Statement, and (ii) the Company and
HCPI shall each notify the other as promptly as practicable after the receipt by
it of any written or oral comments of the SEC on, or of any written or oral
request by the SEC for amendments or supplements to, the Joint Proxy
Statement/Prospectus or the Registration Statement, and shall promptly supply
the other with copies of all correspondence between it or any of its
Representatives and the SEC with respect to any of the foregoing filings.

     (d) The Company and HCPI shall each take all action necessary to duly call
the Company Stockholders Meeting and the HCPI Stockholders Meeting,
respectively, each to be held as promptly as practicable for the purpose of
voting upon the approval of this Agreement and the Merger. Subject to the right
of the Company Board to withdraw, amend or modify such recommendation in
accordance with Section 6.3, each of the Company and HCPI shall, through


                                       55
<PAGE>


its respective board of directors, (i) recommend to their respective
stockholders adoption of this Agreement and approval of the Merger and related
matters, (ii) coordinate and cooperate with respect to the timing of the Company
Stockholders Meeting and HCPI Stockholders Meeting, and (iii) use their
reasonable best efforts to hold the Company Stockholders Meeting and HCPI
Stockholders Meeting on the same day. Without limiting the generality of the
foregoing, the Company agrees that its obligations pursuant to this Section
6.1(d) to call for and conduct the Company Stockholders Meeting shall not be
affected by the commencement, public proposal or communication to the Company of
any Acquisition Proposal.

     Section 6.2 COOPERATION; NOTICE; CURE. Subject to compliance with
applicable law, including any law regarding the exchange of information, from
the date hereof and until the Effective Time, each of HCPI and the Company shall
confer on a regular basis with one or more Representatives of the other Party to
report on the general status of ongoing operations. Each of HCPI and the Company
shall promptly notify the other in writing of, and will use all commercially
reasonable efforts to cure before the Closing Date, any event, transaction or
circumstance, as soon as practical after it becomes known to such Party, that
causes or will, with the passage of time, cause any covenant or agreement of
HCPI or the Company, as the case may be, under this Agreement to be breached in
any material respect or that renders or will, with the passage of time, render
untrue in any material respect any representation or warranty of HCPI or the
Company contained in this Agreement. No notice given pursuant to this paragraph
shall have any effect on the representations, warranties, covenants or
agreements contained in this Agreement for purposes of determining satisfaction
of any condition contained herein. The Company will reasonably cooperate with
HCPI and, immediately prior to the Merger, take any commercially reasonable
actions (including restructuring their ownership of Texas properties) reasonably
requested by HCPI, to minimize HCPI's Texas tax liabilities arising subsequent
to the Merger.

     Section 6.3 NO SOLICITATION.

     (a) The Company shall immediately cease and terminate any existing
solicitation, initiation, encouragement, activity, discussion or negotiation
with any Persons conducted heretofore by the Company, its Subsidiaries or any of
their respective Representatives with respect to any proposed, potential or
contemplated Acquisition Proposal.

     (b) From and after the date hereof, without the prior written consent of
HCPI, the Company will not, will not authorize or permit any of its Subsidiaries
to, and shall use its reasonable best efforts to cause any of its or their
respective Representatives not to, directly or indirectly, (i) solicit, initiate
or encourage (including by way of furnishing information) or take any other
action to facilitate any inquiries or the making of any proposal which
constitutes or may reasonably be expected to lead to an Acquisition Proposal
from any Person, or (ii) engage in any discussion or negotiations with, or
provide any non-public information to, any Person (or group of Persons) other
than HCPI or its Representatives concerning an Acquisition Proposal, or (iii)
enter into any agreement with respect to any Acquisition Proposal; provided,
however, that nothing contained in this Section 6.3(b) shall prevent the Company
or the Company Board from furnishing non-public information to, or entering into
discussions or negotiations with, any


                                       56
<PAGE>


Person in connection with an unsolicited, bona fide written proposal for an
Acquisition Proposal by such Person or recommending such Acquisition Proposal to
its stockholders, if and only to the extent that (1) such Person has made a
written proposal to the Company Board to consummate an Acquisition Proposal, (2)
the Company Board determines in good faith, after consultation with a financial
advisor of nationally recognized reputation, that such Acquisition Proposal if
accepted is reasonably capable of being consummated on substantially the terms
proposed, and after taking into account the strategic benefits anticipated to be
derived from the Merger and the long term prospects of HCPI and the Company as a
combined company, would, if consummated, result in a transaction that would be
more favorable to the holders of Company Common Stock than the transaction
contemplated by this Agreement (a "Superior Proposal"), (3) the failure to take
such action would, in the reasonable good faith judgment of the Company Board,
after consultation with outside legal counsel, be inconsistent with its
fiduciary duties to the Company's stockholders under applicable law, and (4)
prior to furnishing such non-public information to, or entering into discussions
or negotiations with, such Person, the Company Board receives from such Person
an executed confidentiality and standstill agreement with material terms no less
favorable to the Company than those contained in the Confidentiality Agreement.
The Company agrees not to release any Person from, or waive any provision of,
any standstill agreement to which it is a party or any confidentiality agreement
between it and another Person who has made, or who may reasonably be considered
likely to make, an Acquisition Proposal, unless the failure to take such action
would, in the reasonable good faith judgment of the Company Board, after
consultation with outside legal counsel, be inconsistent with its fiduciary
duties to the Company's stockholders under applicable law.

     (c) The Company shall notify HCPI in writing of any such inquiries, offers
or proposals (including, without limitation, the terms and conditions of any
such offers or proposals, any amendments or revisions, and the identity of the
Person making it), as promptly as practicable following the receipt thereof, and
shall keep HCPI informed of the status and material terms of any such inquiry,
offer or proposal.

     (d) The Company shall notify HCPI promptly after receipt by the Company or,
to the Company's Knowledge, any of its Representatives of any Acquisition
Proposal or any request for non-public information in connection with an
Acquisition Proposal or for access to the properties, books or records of the
Company by a Person that informs such party that is considering making or has
made an Acquisition Proposal. Such notice shall be in writing and shall indicate
the identity of the offeror and the terms and conditions of such proposal,
inquiry or contact. The Company shall keep HCPI informed of the status
(including any change to the material terms) of any such Acquisition Proposal or
request for non-public information.

     (e) Neither the Company Board nor any committee thereof shall withdraw or
modify, or propose to withdraw or modify, in a manner adverse to HCPI the
approval or recommendation by the Company Board of this Agreement or the Merger
unless, following the receipt of a Superior Proposal, failing to withdraw or
modify such approval or recommendation in the reasonable good faith judgment of
the Company Board, after the receipt of advice from outside legal counsel, would
be inconsistent with its fiduciary duties to the Company's stockholders under
applicable law; provided, however, that, the Company Board shall submit this


                                       57
<PAGE>


Agreement to the Company's stockholders for approval, whether or not the Company
Board at any time subsequent to the date hereof determines that this Agreement
is no longer advisable or recommends that the stockholders of the Company reject
it or otherwise modifies or withdraws its recommendation. Unless the Company
Board has withdrawn its recommendation of this Agreement in compliance herewith,
the Company shall use all lawful efforts to solicit from stockholders of the
Company proxies in favor of the approval and adoption of this Agreement and the
Merger and to secure the vote or consent of stockholders required by the DGCL
and its certificate of incorporation and bylaws to approve and adopt this
Agreement and the Merger.

     (f) Nothing contained in this Agreement shall prohibit the Company from
complying with Rule 14e-2 promulgated under the Exchange Act with regard to a
tender or exchange offer or from making any other disclosures to its
stockholders to the extent required by law.

     Section 6.4 ACCESS TO INFORMATION. Upon reasonable notice, each of HCPI and
the Company (and each of their respective Subsidiaries) shall afford to the
other Party and its Representatives reasonable access, during normal business
hours during the period prior to the Effective Time, to all its personnel,
properties, books, contracts, commitments and records and, during such period,
each of HCPI and the Company shall, and shall cause each of its respective
Subsidiaries to, furnish promptly to the other (a) copies of monthly financial
reports and development reports relating to the business of the Company or the
business of HCPI, as the case may be, that are normally prepared by the Company
or HCPI, as the case may be, in its ordinary course of business, (b) a copy of
each report, schedule, registration statement and other documents filed or
received by it during such period pursuant to the requirements of federal or
state securities laws and (c) all other information concerning its business,
Assets, personnel and tax status as the other Party may reasonably request;
provided, however the foregoing shall not require the Company or HCPI to permit
any inspection or disclose any information that would result in the disclosure
of confidential information of third parties or violate a confidentiality
obligation of such party. Each Party making such requests will hold any such
information furnished to it by the other Party or Parties which is nonpublic in
confidence in accordance with the Confidentiality Agreement dated as of June 30,
1999, between HCPI and the Company (the "Confidentiality Agreement"). All
requests for information made pursuant to this Section shall be directed to an
executive officer of the Company or HCPI, as the case may be, or such Person
designated by such officers. No information or knowledge obtained in any
investigation pursuant to this Section 6.4 shall affect or be deemed to modify
any representation or warranty contained in this Agreement or the conditions to
the obligations of the Parties to consummate the Merger.

     Section 6.5 GOVERNMENTAL APPROVALS.

     (a) The Parties shall cooperate with each other and use their reasonable
best efforts to promptly prepare and file all necessary documentation, to effect
all applications, notices, petitions and filings, to obtain as promptly as
practicable all permits, registrations, licenses, consents, variances,
exemptions, orders, approvals and authorizations of all third parties and
Governmental Entities which are necessary to consummate the transactions
contemplated by


                                       58
<PAGE>


this Agreement ("Governmental Approvals"), and to comply with the terms and
conditions of all such Governmental Approvals. Each of the Parties shall use
their reasonable best efforts to, and shall use their reasonable best efforts to
cause their respective Representatives and other Affiliates to, file within 30
days after the date hereof, and in all events shall file within 60 days after
the date hereof, all required initial applications and documents in connection
with obtaining the Governmental Approvals and shall act reasonably and promptly
thereafter in responding to additional requests in connection therewith. HCPI
and the Company shall have the right to review in advance, and to the extent
practicable, each will consult the other on, in each case subject to applicable
laws relating to the exchange of information, all the information relating to
HCPI and the Company, as the case may be, and any of their respective
Subsidiaries, directors, officers and stockholders which appear in any filing
made with, or written materials submitted to, any third party or any
Governmental Entity in connection with the transactions contemplated by this
Agreement. Without limiting the foregoing, each of HCPI and the Company (the
"Notifying Party") will notify the other promptly of the receipt of comments or
requests from Governmental Entities relating to Governmental Approvals, and will
supply the other Party with copies of all correspondence between the Notifying
Party or any of its Representatives and Governmental Entities with respect to
Governmental Approvals.

     (b) HCPI and the Company shall promptly advise each other upon receiving
any communication from any Governmental Entity whose consent or approval is
required for consummation of the transactions contemplated by this Agreement
which causes such Party to believe that there is a reasonable likelihood that
any approval needed from a Governmental Entity will not be obtained or that the
receipt of any such approval will be materially delayed. HCPI and the Company
shall take any and all actions reasonably necessary to vigorously defend, lift,
mitigate and rescind the effect of any litigation or administrative proceeding
adversely affecting this Agreement or the transactions contemplated hereby or
thereby, including, without limitation, promptly appealing any adverse court or
administrative order or injunction to the extent reasonably necessary for the
foregoing purposes.

     Section 6.6 PUBLICITY. HCPI and the Company shall agree on the form and
content of the initial press release regarding the transactions contemplated
hereby and thereafter shall consult with each other before issuing any press
release or other public statement with respect to any of the transactions
contemplated hereby and shall not issue any such press release or make any such
public statement prior to such consultation, except as may be required by law or
obligations pursuant to any listing agreement with, or rules of any national
securities exchange.

     Section 6.7 BENEFIT PLANS. Except as provided in Section 2.8 and Section
6.20 hereof, HCPI shall, and shall cause the Surviving Corporation to, from and
after the Effective Time, (i) comply with the Employee Plans of the Company in
accordance with their terms, (ii) provide former employees of the Company who
remain as employees of the Surviving Corporation with employee benefit plans no
less favorable in the aggregate than those provided to similarly situated
employees of HCPI, (iii) provide employees of the Company who remain as
employees of the Surviving Corporation credit for years of service with the
Company or any of its Subsidiaries prior to the Effective Time for (A) the
purpose of eligibility and vesting but not


                                       59
<PAGE>

benefit accrual under the Employee Plans of HCPI, and (B) any and all
pre-existing condition limitations and eligibility waiting periods under group
health plans of HCPI, and (iv) cause to be credited to any deductible
out-of-pocket expense under any Employee Plans of HCPI any deductibles or
out-of-pocket expenses incurred by employees of the Company and their
beneficiaries and dependents during the portion of the calendar year prior to
their participation in Employee Plans of HCPI. HCPI shall, and shall cause the
Surviving Corporation to, honor in accordance with their terms, all Employee
Plans of the Company and its Subsidiaries, vested or accrued benefit obligations
to, and contractual rights of, current and former employees of the Company and
its Subsidiaries.

     Section 6.8 INDEMNIFICATION.

     (a) From and after the Effective Time, HCPI agrees that it will, and will
cause the Surviving Corporation to, indemnify and hold harmless each present and
former director and officer of the Company (the "Indemnified Parties"), against
any costs or expenses (including attorneys' fees), judgments, fines, losses,
claims, damages, liabilities or amounts paid in settlement incurred in
connection with any Action whether civil, criminal, administrative or
investigative, arising out of or pertaining to matters existing or occurring at
or prior to the Effective Time, whether asserted or claimed prior to, at or
after the Effective Time, to the fullest extent that HCPI is permitted under
applicable law.

     (b) For a period of six years after the Effective Time, HCPI shall maintain
or shall cause the Surviving Corporation to maintain in effect a directors' and
officers' liability insurance policy covering those persons who are currently
covered by the Company's directors' and officers' liability insurance policy
(copies of which have been heretofore delivered by the Company to HCPI) with
coverage in amount and scope at least as favorable as the Company's existing
coverage; provided that in no event shall HCPI or the Surviving Corporation be
required to expend, in the aggregate, in excess of $360,000 per year in payment
of the annual premium for such coverage; and if such premium would at any time
exceed $360,000 per year, then HCPI or the Surviving Corporation shall maintain
insurance policies which provide the maximum and best coverage available at an
annual premium equal to $360,000 per year.

     (c) If the Surviving Corporation or any of its successors or assigns (i)
shall consolidate with or merge into any other corporation or entity and shall
not be the continuing or surviving corporation or entity of such consolidation
or merger or (ii) shall transfer all or substantially all of its Assets to any
Person, then, and in each such case, proper provisions shall be made so that the
successors and assigns of the Surviving Corporation shall assume all of the
obligations of the Surviving Corporation set forth in this Section 6.8.

     (d) The provisions of this Section 6.8 are intended to be an addition to
the rights otherwise available to the current officers and directors of the
Company by law, charter, statute, bylaw or agreement, and shall operate for the
benefit of, and shall be enforceable by, each of the Indemnified Parties, their
heirs and their Representatives.

     Section 6.9 AFFILIATE AGREEMENTS. No later than 45 days prior to the
Closing the Company shall deliver to HCPI a list identifying, in the view of the
Company, each person


                                       60
<PAGE>


who may be, at the time of the Company Stockholder Meeting, a Company Affiliate.
The Company shall provide to HCPI such information and documents as HCPI shall
reasonably request for purposes of reviewing such list and shall notify HCPI in
writing regarding any change in the identity of the Company Affiliates prior to
the Closing Date; provided, however, that no such Person identified to HCPI
shall be added to the list of Company Affiliates if HCPI shall receive from the
Company, on or before the date of the Company Stockholder Meeting, an opinion of
counsel reasonably satisfactory to HCPI to the effect that such Person is not a
Company Affiliate. The Company shall use its reasonable best efforts to deliver
or cause to be delivered to HCPI as promptly as practicable but in no event
later than 35 days prior to the Closing (and in any case prior to the Effective
Time) an Affiliate Agreement from each of its Affiliates.

     Section 6.10 TAX TREATMENT OF REORGANIZATION.

     (a) The Parties intend the Merger to qualify as a reorganization under
Section 368(a) of the Code and shall use their best efforts (and shall cause
their respective Subsidiaries to use their best efforts) to cause the Merger to
so qualify. Neither the Company, HCPI, nor any of their respective Subsidiaries
or other Affiliates shall take any action, or fail to take any action, that is
not specifically provided for by this Agreement that would or would be
reasonably likely to adversely affect the treatment of the Merger as a
reorganization under Section 368(a) of the Code. HCPI and the Company shall, and
shall cause their respective Subsidiaries to, take the position for all purposes
that the Merger qualifies as a reorganization under that Section of the Code.

     (b) HCPI and the Company shall cooperate and use their best efforts in
obtaining the opinions of Sullivan & Cromwell, counsel to the Company, and
Latham & Watkins, counsel to HCPI, dated as of the Closing Date, to the effect
that the Merger will qualify for federal income tax purposes as a reorganization
within the meaning of Section 368(a) of the Code.

     Section 6.11 FURTHER ASSURANCES AND ACTIONS.

     (a) Subject to the terms and conditions herein, each of the Parties agrees
to use its reasonable efforts to take, or cause to be taken, all appropriate
action, and to do, or cause to be done, all things necessary, proper or
advisable on its part under applicable laws and regulations to consummate and
make effective the transactions contemplated by this Agreement, including,
without limitation, (i) using their respective reasonable efforts to obtain all
licenses, permits, consents, approvals, authorizations, qualifications and
orders of Governmental Entities and parties to contracts with each Party as are
necessary for consummation of the transactions contemplated by this Agreement,
and (ii) to fulfill all conditions precedent applicable to such Party pursuant
to this Agreement. HCPI further agrees to make all necessary filings in
connection with the issuance of the HCPI Series C Preferred Stock.
Notwithstanding anything to the contrary set forth in this Agreement, neither
the Company nor HCPI shall be precluded from complying with federal securities
laws.

Agreement.

set forth in this Agreement, nothing in this Agreement shall prohibit the

qualification as a REIT within the meaning of Sections 856-860 of the Code for

senior officer of the Company), the Company will not owe any federal income or

                        TERMINATION, AMENDMENT AND WAIVER

     Section 8.1 TERMINATION. This Agreement may be terminated at any time
before the Effective Time (except as otherwise provided), whether before or
after the approval of


                                       66
<PAGE>


the stockholders of the Company and HCPI referred to in Sections 7.1(a) and (b),
as the case may be, as follows:

     (a) by mutual written consent of each of HCPI and the Company;

     (b) by either the Company or HCPI, if the Effective Time shall not have
occurred on or before January 31, 2000 (the "Termination Date"); provided
however, that the right to terminate this Agreement under this Section 8.1(b)
shall not be available to any Party whose failure to fulfill any obligation
under this Agreement has been the cause of, or resulted in, the failure of the
Effective Time to occur on or before the Termination Date;

     (c) by either the Company or HCPI, if a Governmental Entity shall have
issued an order, decree or injunction having the effect of making the Merger
illegal or permanently prohibiting the consummation of the Merger, and such
order, decree or injunction shall have become final and nonappealable;

     (d) by either the Company or HCPI, if there shall have been a breach by the
other of any of its (i) representations or warranties contained in this
Agreement, which breach would result in the failure to satisfy one or more of
the conditions set forth in Section 7.2(a) (in the case of a breach by HCPI) or
Section 7.3(a) (in the case of a breach by the Company), or (ii) covenants or
agreements contained in this Agreement, which breach would result in the failure
to satisfy one or more of the conditions set forth in Section 7.2(b) (in the
case of a breach by HCPI) or Section 7.3(b) (in the case of a breach by the
Company), and in any such case such breach shall be incapable of being cured or,
if capable of being cured, shall not have been cured within 30 days after
written notice thereof shall have been received by the Party alleged to be in
breach;

     (e) by HCPI, if the Company Board or any committee of the Company Board (i)
shall withdraw or modify in any manner adverse to HCPI, its approval or
recommendation of this Agreement or the Merger, (ii) shall fail to reaffirm such
approval or recommendation within five Business Days of HCPI's request, (iii)
shall approve or recommend any Acquisition Proposal or Acquisition Transaction
or (iv) shall resolve to take any of the actions specified in clauses (i), (ii)
or (iii) above; or

     (f) by either the Company or HCPI, if the stockholders' meetings to
consider the Merger shall have been held by the Company and HCPI, as the case
may be, and the required approval of the stockholders of the Company or HCPI
shall not have been obtained at any such stockholders' meetings, including any
adjournments or postponements.

     Section 8.2 EFFECT OF TERMINATION.

     (a) In the event that:

          (i) any Person shall have made an Acquisition Proposal to the Company
     or to its stockholders and thereafter this Agreement is terminated (A) by
     HCPI pursuant to Sections 8.1(b) or 8.1(d) or (B) by either Party pursuant
     to Section 8.1(f) as a result of the required approval of the Company
     stockholders having not been obtained; or


                                       67
<PAGE>


          (ii) this Agreement is terminated by HCPI pursuant to Section 8.1(e),
     then, in any such case, if the Company is not also entitled to terminate
     this Agreement by reason of Section 8.1(b), Section 8.1(d) or Section
     8.1(f) as a result of the required approval of HCPI's stockholders having
     not been obtained, the Company shall in no event later than two days after
     such termination pay HCPI the Termination Fee by wire transfer of same day
     funds to a bank account designated by HCPI.

     (b) Unless the Company would be entitled to terminate this Agreement
pursuant to Sections 8.1(b) or 8.1(d) or pursuant to Section 8.1(f) as a result
of the required vote of HCPI's stockholders having not been obtained, in the
event that this Agreement is terminated (i) by HCPI pursuant to Sections 8.1(b),
8.1(d), or 8.1(e) or (ii) by either Party pursuant to Section 8.1(f) as a result
of the required approval of the Company's stockholders having not been obtained,
then, after any such termination, the Company shall reimburse HCPI, promptly
after being requested to do so by HCPI, for up to $2,000,000 toward the payment
of the out-of-pocket costs and expenses incurred by HCPI in connection with this
Agreement and the transactions contemplated hereby, including, without
limitation, fees and expenses of accountants, attorneys, financial advisors
(except for any contingent fee of a financial advisor for which a contingency
has not been satisfied), commercial banks, experts and consultants and fees and
expenses otherwise allocated to HCPI pursuant to this Agreement. If a payment is
due under Section 8.2(a), the payment to HCPI of the amount set forth in this
Section 8.2(b) shall be made in addition to the payment required to be made
pursuant to Section 8.2(a).

     (c) Unless HCPI would be entitled to terminate this Agreement pursuant to
Sections 8.1(b) or 8.1(d) or pursuant to Section 8.1(f) as a result of the
required vote of the Company's stockholders having not been obtained, in the
event that this Agreement is terminated (i) by the Company pursuant to Sections
8.1(b) or 8.1(d), or (ii) by either Party pursuant to Section 8.1(f) as a result
of the required approval of the HCPI's stockholders having not been obtained,
then, after any such termination, HCPI shall reimburse the Company, promptly
after being requested to do so by the Company, for up to $2,000,000 toward the
payment of the out-of-pocket costs and expenses incurred by the Company in
connection with this Agreement and the transactions contemplated hereby,
including, without limitation, fees and expenses of accountants, attorneys,
financial advisors (except for any contingent fee of a financial advisor for
which a contingency has not been satisfied), commercial banks, experts and
consultants and fees and expenses otherwise allocated to the Company pursuant to
this Agreement.

     (d) As used in this Agreement, "Termination Fee" shall be an amount equal
to the lesser of (i) $18,700,000 (the "Base Amount") and (ii) the maximum
amount, if any, that can be paid to HCPI without causing it to fail to meet the
requirements of Sections 856(c)(2) and (3) of the Code for such year determined
as if (a) the payment of such amount did not constitute income described in
Sections 856(c)(2)(A)-(H) and 856(c)(3)(A)-(I) of the Code ("Qualifying
Income"), and (b) HCPI has $1,000,000 of income from unknown sources during such
year which was not Qualifying Income (in addition to any known or anticipated
income of HCPI which was not Qualifying Income), in each case as determined by
independent accountants to HCPI. Notwithstanding the foregoing, in the event
HCPI receives a reasoned opinion from outside counsel or a ruling from the IRS
(the "Tax Guidance") providing that HCPI's receipt of


                                       68
<PAGE>


the Base Amount would either constitute Qualifying Income or would be excluded
from gross income within the meaning of Sections 856(c)(2) and (3) of the Code
(the "REIT Requirements"), the Termination Fee shall be an amount equal to the
Base Amount and the Company shall, upon receiving notice that HCPI has received
the Tax Guidance, pay to HCPI the unpaid Base Amount within five business days.
In the event that HCPI is not able to receive the full Base Amount due to the
above limitations, the Company shall place the unpaid amount in escrow by wire
transfer within three days of termination and shall not release any portion
thereof to HCPI unless and until HCPI receives either one or a combination of
the following once or more often: (i) a letter from HCPI's independent
accountants indicating the maximum amount that can be paid at that time to HCPI
without causing HCPI to fail to meet the REIT Requirements (calculated as
described above) or (ii) the Tax Guidance, in either of which events the Company
shall pay to HCPI the lesser of the unpaid Base Amount or the maximum amount
stated in the letter referred to in (i) above within five business days after
the Company has been notified thereof. The payment of the amount required to be
paid pursuant to Section 8.2(a) in connection with the circumstances described
therein, together with the amount required to be paid pursuant to Section 8.2(b)
(but only to the extent such amount is paid together with the amount set forth
in Section 8.2(a)), shall be compensation and liquidated damages for the loss
suffered by HCPI as a result of the failure of the Merger to be consummated and
to avoid the difficulty of determining damages under such circumstances. Neither
Party shall have any other liability to the other for damages after the payment
of such amounts. The obligation of Company to pay any unpaid portion of the
Termination Fee shall terminate on the December 31 following the date which is
three years from the date of this Agreement. Amounts remaining in escrow after
the obligation of the Company to pay the Termination Fee terminates shall be
released to the Company.

     (e) The Parties acknowledge that the agreements contained in this Section
8.2 are an integral part of the transactions contemplated in this Agreement, and
that, without these agreements, the Parties would not enter into this Agreement;
accordingly, if the Company fails to promptly pay the Termination Fee or the
fees and expenses of HCPI or if HCPI fails to pay the fees and expenses of the
Company, each as required by this Section 8.2, and in order to obtain such
payment the non-defaulting Party commences a suit which results in a judgment
against the defaulting Party for any amount of the fees and expenses set forth
in this Section 8.2, the defaulting Party shall pay to the non-defaulting Party
its costs and expenses (including attorneys' fees) in connection with such suit
together with interest on such amount in respect of the period from the date
such amount became due until the date such amount is paid at the prime rate of
The Chase Manhattan Bank in effect from time to time during such period.

     (f) In the event of termination of this Agreement pursuant to this Article
VIII, this Agreement (other than as set forth in Section 9.1) shall become void
and of no effect with no liability under the terms of the Agreement (other than
as set forth in this Section 8.2) on the part of any Party; provided, however,
no such termination shall relieve any Party from any liability for breach of
this Agreement.

     Section 8.3 EXPENSES. The Surviving Corporation shall pay all charges and
expenses, including those of the Exchange Agent, in connection with the
transactions


                                       69
<PAGE>


contemplated in Article II. Except as otherwise specifically provided herein,
each Party shall bear its own expenses in connection with this Agreement and the
transactions contemplated hereby.

     Section 8.4 AMENDMENT. This Agreement may be amended by the Parties by
action taken by or on behalf of their respective Boards of Directors at any time
before or after any required approval of matters presented in connection with
the Merger by the stockholders of the Company and HCPI; provided, however, that
after any such approval, there shall be made no amendment that by law requires
further approval by such stockholders without the further approval of such
stockholders. This Agreement may not be amended except by an instrument in
writing signed by the Parties.

     Section 8.5 WAIVER. At any time prior to the Closing Date, any Party may
(a) extend the time for the performance of any of the obligations or other acts
of the other Parties hereto, (b) waive any inaccuracies in the representations
and warranties of the other Parties contained herein or in any document
delivered pursuant hereto and (c) waive compliance by any other Party with any
of the agreements or conditions contained herein. Any such extension or waiver
shall be valid if set forth in an instrument in writing signed by the Party or
Parties to be bound thereby. The failure of any Party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

                                  ARTICLE IX.

                            FORM OF AFFILIATE LETTER


Health Care Property Investors, Inc.
4675 MacArthur Court, Suite 900
Newport Beach, California  92660

Ladies and Gentlemen:

     The undersigned has been advised that as of the date of this letter it may
be deemed to be an "affiliate" of American Health Properties, Inc., a Delaware
corporation (the "Company"), as the term "affiliate" is defined for purposes of
paragraphs (c) and (d) of Rule 145 of the rules and regulations (the "Rules and
Regulations") of the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Act"). Pursuant to the terms of the
Agreement and Plan of Merger dated as of August __, 1999 (the "Agreement"),
between Health Care Property Investors, Inc., a Maryland corporation ("HCPI")
and the Company, the Company will be merged with and into HCPI (the "Merger").

     As a result of the Merger, the undersigned may receive shares (the
"Shares") of common stock, par value $1.00 per share, of HCPI (the "HCPI Common
Stock") in exchange for shares of common stock, par value $.01 per share, of the
Company (the "Company Common Stock").

     1. The undersigned represents, warrants and covenants to HCPI that in the
event it receives Shares as a result of the Merger:

          A. It shall not make any sale, transfer or other disposition of the
     Shares in violation of the Act or the Rules and Regulations.

          B. It has carefully read this letter and the Agreement and discussed
     the requirements of such documents and other applicable limitations upon
     its ability to sell, transfer or otherwise dispose of the Shares to the
     extent it determines necessary, with its counsel or counsel of the Company.

          C. It has been advised that the issuance of the Shares pursuant to the
     Merger has been registered with the Commission under the Act on a
     Registration Statement on Form S-4. The undersigned has also been advised
     that, since at the time the Merger was submitted for a vote of the

     obtained by the undersigned from the staff of the Commission, such sale,
     transfer or other disposition is otherwise exempt from registration under
     the Act.

          D. The undersigned does not own in excess of 9.8% of the outstanding
     the Company Common Stock and, upon consummation of the Merger, will not own
     in excess of 9.8% of the outstanding HCPI Common Stock.

          E. The undersigned understands that HCPI is under no obligation to
     register the sale, transfer or other disposition of the Shares by it or on
     its behalf under the Act, or except as expressly set forth in the
     Agreement, to take any other action necessary in order to make compliance
     with an exemption from such registration available.

          F. The undersigned also understands that HCPI may give stop transfer
     instructions to its transfer agent with respect to the Shares to enforce
     the restrictions on the undersigned set forth herein and that it reserves
     the right to place on the certificates for HCPI Common Stock issued to the
     undersigned, or any substitutions therefor, a legend stating in substance:

          "The securities represented by this certificate have been
          issued in a transaction to which Rule 145 promulgated under
          the Securities Act of 1933 applies and may be sold or
          otherwise transferred only in compliance with the
          requirements of Rule 145 or pursuant to a registration
          statement under said Act or an exemption from such
          registration."

          G. The undersigned also understands that unless the transfer by it of
     the Shares has been registered under the Act or is a sale made in
     conformity with the provisions of Rule 145, HCPI reserves the right to put
     the following legend on the certificates issued to transferees of the
     undersigned:

          "The securities represented by this certificate have not
          been registered under the Securities Act of 1933 and were
          acquired from a person who received such shares in a
          transaction to which Rule 145, promulgated under the
          Securities Act of 1933, applies. The securities have been
          acquired by the holder not with a view to, or for resale in
          connection with, any distribution thereof within the meaning
          of the Securities Act of 1933 and may not be sold, pledged
          or otherwise transferred except in accordance with an
          exemption from the registration requirements of the
          Securities Act of 1933."

     Execution of this letter should not be considered an admission on the part
of the undersigned that it is an "affiliate" of the Company as described in the
first paragraph of this


                                 A-2

letter or as a waiver of any rights it may have to object to any claim that it
is such an affiliate on or after the date of this letter.

     2. By HCPI's acceptance of this letter, HCPI hereby agrees with
the undersigned to the extent applicable as follows:

          A. For so long as and to the extent necessary to permit the
     undersigned to sell HCPI Common Stock pursuant to Rule 145 and, to the
     extent applicable, Rule 144 under the Act, HCPI shall (a) use its
     reasonable efforts to (i) file, on a timely basis, all reports and data
     required to be filed with the Commission by it pursuant to Section 13 of
     the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
     (ii) furnish to the undersigned upon request a written statement as to
     whether HCPI complied with such reporting requirements during the 12 months
     preceding any proposed sale of HCPI Common Stock by the undersigned under
     Rule 145, and (b) otherwise use its reasonable efforts to permit such sales
     pursuant to Rule 145 and Rule 144. HCPI has filed all reports required to
     be filed with the Commission under Section 13 of the Exchange Act during
     the preceding 12 months.

          B. It is understood and agreed that certificates with the legend set
     forth in subparagraphs F and G of Paragraph 1 above will be substituted by
     delivery of certificates without such legend if (i) transfer by the
     undersigned of HCPI Common Stock of the undersigned has been registered
     under the Act or is a sale made in conformity with the provisions of Rule
     145, (ii) one year shall have elapsed from the date the undersigned
     acquired the Shares and the provisions of Rule 145(d)(2) are then available
     to the undersigned, (iii) two years shall have elapsed from the date the
     undersigned acquired HCPI Common Stock received in the Merger and the
     provisions of Rule 145(d)(3) are then available to the undersigned, or (iv)
     HCPI has received either an opinion of counsel, which opinion and counsel
     shall be reasonably satisfactory to it, or a "no-action" or interpretive
     letter obtained by the undersigned from the staff of the Commission, to the
     effect that the restrictions imposed by Rule 144 and Rule 145 under the Act
     no longer apply to the undersigned.

                                                     Very truly yours,

Suite 1800
Englewood, Colorado 80111


Ladies and Gentlemen:

     We have acted as counsel to Health Care Property Investors, Inc., a
Maryland corporation (the "Company"), in connection with the merger (the
"Merger") of American Health Properties, Inc., a Delaware corporation ("AHP")
with and into the Company, with the Company as the surviving corporation,
pursuant to that certain Agreement and Plan of Merger between the Company and
AHP dated as of August __, 1999 (together with all exhibits and amendments
thereto, the "Merger Agreement"). This opinion is being rendered to you pursuant
to Section 7.2(e) of the Merger Agreement.

     In formulating our opinion, we examined, and with your consent relied upon,
such documents as we deemed appropriate, including (i) the Merger Agreement,
(ii) the Joint Proxy Statement/Prospectus filed by the Company and AHP with the
Securities and Exchange Commission (the "Commission") on [Month] [day], 1999
(the "Joint Proxy Statement"), and (iii) the Registration Statement on Form S-4,
registration number [___________], as filed by the Company with the Commission
on [Month] [day], 1999, in which the Joint Proxy Statement is included as a
prospectus (with all amendments and exhibits thereto, the "Registration
Statement"). In addition, we have obtained such additional information as we
deemed relevant and necessary through consultation with various officers and
representatives of the Company and AHP.

     This opinion is based on various facts and assumptions, including the facts
set forth in the Registration Statement concerning the business, properties, and
governing documents of the Company and its subsidiaries. We have also been
furnished with, and with your consent have relied upon, certain representations
made by the Company with respect to factual matters through a certificate of an
officer of the Company (the "Officer's Certificate").


<PAGE>


     In our capacity as such counsel, we have made such legal and factual
examinations and inquiries, including an examination of originals or copies
certified or otherwise identified to our satisfaction of such documents,
corporate records and other instruments, as we have deemed necessary or
appropriate for purposes of this opinion. In our examination, we have assumed
the authenticity of all documents submitted to us as originals, the genuineness
of all signatures thereon, the legal capacity of natural persons executing such
documents and the conformity to authentic original documents of all documents
submitted to us as copies.

     We are opining herein as to the effect on the subject transaction only of
the federal income tax laws of the United States and we express no opinion with
respect to the applicability thereto, or the effect thereon, of other federal
laws, the laws of any state or other jurisdiction or as to any matters of
municipal law or the laws of any other local agencies with any state.

     Based upon such facts, assumptions, and representations, including the
facts set forth in the Registration Statement and the Officer's Certificate, it
is our opinion that (i) commencing with the Company's taxable year ending
December 31, 1985, the Company has been organized in conformity with the
requirements for qualification and taxation as a "real estate investment trust"
under the Internal Revenue Code of 1986, as amended (the "Code"), and (ii) its
method of operation has enabled it to meet, and its proposed method of operation
will enable it to continue to meet the requirements for qualification and
taxation as a "real estate investment trust" under the Code.

     No opinion is expressed as to any matter not discussed herein.

     This opinion is only being rendered to you as of the date of this letter,
and we undertake no obligation to update this opinion subsequent to the date
hereof. This opinion is based on various statutory provisions, regulations
promulgated thereunder and interpretations thereof by the Internal Revenue
Service and the courts having jurisdiction over such matters, all of which are
subject to change either prospectively or retroactively. Also, any variation or
difference in the facts from those set forth in the Registration Statement or
the Officer's Certificate may affect the conclusions stated herein.

     This opinion is rendered to you solely in connection with the satisfaction
of Section 7.2(e) of the Merger Agreement. This opinion may not be relied upon
by you for any other purpose, or furnished to, quoted to or relied upon by any
other person, firm or corporation for any purpose, without our prior written
consent.

                                              Very truly yours,

Ladies and Gentlemen:

     We have acted as counsel to American Health Properties, Inc., a Delaware
corporation (the "Company"), in connection with the merger (the "Merger") of the
Company with and into Health Care Property Investors, Inc., a Maryland
corporation ("Parent"), with Parent as the surviving corporation, pursuant to
that certain Agreement and Plan of Merger between Parent and the Company dated
as of August __, 1999, (together with all exhibits and amendments thereto, the

furnished with, and with your consent have relied upon, certain representations

assumed, with your consent, the accuracy of the opinion of Sullivan & Cromwell,
dated the date hereof, addressed to Parent, with respect to the federal income
tax treatment of the Psychiatric Group Preferred Stock (as such term is defined
in the Merger Agreement) previously issued by

     In our capacity as such counsel, we have made such legal and factual

certified or otherwise identified to our satisfaction of such documents,

qualification and taxation as a "real estate investment trust" under the
Internal Revenue Code of 1986, as amended (the "Code"), and (ii) its method of

                        [Sullivan & Cromwell Letterhead]


Health Care Property Investors, Inc.
4676 MacArthur Court, Suite 900
Newport Beach, CA 92660

Dear Sirs:

     We acted as counsel to American Health Properties, Inc., a Delaware
corporation (the "Company"), in connection with its issuance of Psychiatric
Group Preferred Stock (the "Psychiatric Group Stock") to holders of record on
July 14, 1995 of its Common Stock, as more fully described in the Information
Statement dated June 29, 1995. In that transaction, each holder of Common Stock
of the Company received as a dividend one share of Psychiatric Group Stock for
every ten shares of Common Stock the holder owned. The Psychiatric Group Stock
was redeemed by the Company in May of 1999.

     You have asked whether, in our opinion, the issuance of the Psychiatric
Group Stock and the payment of dividends thereon during the period it was
outstanding affected the qualification of the Company as a real estate
investment trust (a "REIT") within the meaning of Section 856 of the Internal
Revenue Code (the "Code"). In rendering this opinion, we have reviewed such
documents and other factual matters and such matters of law as we have
considered necessary or appropriate. In our opinion, the Psychiatric Group Stock
was equity for federal income tax purposes, because the holders of the
Psychiatric Group Stock had no creditor or other non-equity type rights against
the Company and possessed all three rights that are the cornerstone of an equity
interest: (i) the right to vote in the election of directors and other matters
put to the shareholders of the Company, (ii) the right to participate in the
earnings of the Company through the payment of dividends and (iii) the right to
share in the net assets of the Company upon its liquidation.

     Although there is no authority bearing directly on the treatment of
"targeted stock" such as the Psychiatric Group Stock, in our opinion the
Psychiatric Group Stock was a class of equity of the Company for federal income
tax purposes because (i) as a matter of Delaware law, the Psychiatric Group
Stock was stock of the Company, (ii) the holders of such stock had rights only
against the Company and had no direct rights with respect to the Psychiatric
Group assets or subsidiaries, (iii) the holders of such stock had no voting
rights with

<PAGE>

Health Care Property Investors
Page 2


respect to the Psychiatric Group subsidiaries and voted only on matters put to
the shareholders of the Company, (iv) the economic expectations of such holders
represented only the intentions of the Board of Directors of the Company, and
not legally enforceable rights of the holders, (v) the Psychiatric Group assets
were available to satisfy creditors of the Company and (vi) the Psychiatric
Group assets were not isolated in a separate subsidiary but were held in
significant part directly by the Company.

     Under Section 562(c) of the Code and Treasury Regulations Section
1.562-2(a), distributions by the Company with respect to its Psychiatric Group
Stock or Common Stock were not "preferential dividends" as long as the
distributions (i) were without preference among shares in any given class and
(ii) were without preference among shares of different classes except to the
extent a class is entitled to a preference.

     In our opinion, the Psychiatric Group Stock and Common Stock were separate
classes of stock of the Company for purposes of Section 562(c) because (i) the
Psychiatric Group Stock and the Common Stock were separate classes of stock for
corporate law purposes, (ii) the economic expectations of the holders of each
class were different and (iii) the voting and liquidation rights of the holders
of each class were different.

     Although there is no authority bearing directly on the application of
preferential dividends under Section 562(c) of the Code to "targeted stock" such
as the Psychiatric Group Stock, in our opinion dividends paid on the Psychiatric
Group Stock and Common Stock were not "preferential" under Section 562(c) of the
Code because (i) the dividends paid by the Company did not deprive either class
of a dividend to which that class was entitled and neither class received a
dividend to which it was not entitled and (ii) concluding that the dividends
paid on the Psychiatric Group Stock and Common Stock of the Company were not
preferential is consistent with the purpose of Section 562(c) and not
inconsistent with any policy underlying the REIT distribution, income, asset or
shareholder tests.

                                                     Very truly yours,
