Dear Sirs:

     Health Care Property Investors, Inc., a Maryland corporation (the
"Company"), confirms its agreement with Merrill Lynch & Co., Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and each of the other
Underwriters named in Schedule A hereto (collectively, the "Underwriters", which
term shall also include any underwriter substituted as hereinafter provided in
Section 10 hereof), for whom Merrill Lynch is acting as representative (in such
capacity, Merrill Lynch shall hereinafter be referred to as the
"Representative"), with respect to the sale by the Company and the purchase by
the Underwriters, acting severally and not jointly, of the respective numbers of
shares of Common Stock, par value $1.00 per share, of the Company ("Common
Stock") set forth in said schedule A, and with respect to the grant by the
Company to the Underwriters, acting severally and not jointly, of the option
described in Section 2(b) hereof to purchase all or any part of 525,000
additional shares of Common Stock to cover over-allotments.  The aforesaid
3,500,000 shares of Common Stock (the "Initial Securities") to be purchased by
the Underwriters and all or any part of the shares of Common Stock subject to
the option described in Section 2(b) hereof (the "Option Securities") are
collectively hereinafter called the "Securities."

                                       1


     The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-57163) and a related
preliminary prospectus for the registration under the Securities Act of 1933, as
amended (the "1933 Act") of Common Stock, including the Securities, preferred
stock, par value $1.00 per share ("Preferred Stock"), and debt securities
(collectively, the "Registered Securities"), which registration statement has
been declared effective by the Commission and copies of which have heretofore
been delivered to you.  Such registration statement, in the form in which it was
declared effective, as amended through the date hereof, including all documents
incorporated or deemed to be incorporated by reference therein through the date
hereof, is hereinafter referred to as the "Original Registration Statement."
Any registration statement filed pursuant to Rule 462(b) of the rules and
regulations of the Commission under the 1933 Act (the "1933 Act Regulations") is
herein referred to as the "Rule 462(b) Registration Statement."  The Original
Registration Statement, together with any Rule 462(b) Registration Statement, is
hereinafter referred to as the "Registration Statement."  The Company proposes
to file with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations
the Prospectus Supplement (as defined in Section 3(i) hereof) relating to the
Securities and the prospectus dated August 27, 1998 (the "Base Prospectus")
relating to the Registered Securities, and has previously advised you of all
further information (financial and other) with respect to the Company set forth
therein.  The Base Prospectus together with the Prospectus Supplement, in their
respective forms on the date hereof (being the forms in which they are to be
filed with the Commission pursuant to Rule 424(b) of the 1933 Act Regulations),
including all documents incorporated or deemed to be incorporated by reference
therein through the date hereof, are hereinafter referred to as, collectively,
the "Prospectus," except that if any revised prospectus or prospectus supplement
shall be provided to the Underwriters by the Company for use in connection with
the offering and sale of the Securities which differs from the Prospectus
(whether or not such revised prospectus or prospectus supplement is required to
be filed by the Company pursuant to Rule 424(b) of the 1933 Act Regulations),
the term "Prospectus" shall refer to such revised prospectus or prospectus
supplement, as the case may be, from and after the time it is first provided to
the Underwriters for such use.  Unless the context otherwise requires, all
references in this Agreement to documents, financial statements and schedules
and other information which is "contained", "included", "stated", "described in"
or "referred to" in the Registration Statement or the Prospectus (and all other
references of like import) shall be deemed to mean and include all such
documents, financial statements and schedules and other information which is or
is deemed to be incorporated by reference in the Registration Statement or the
Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement or the Prospectus shall
be deemed to mean and include the filing of any document under the Securities
Exchange Act of 1934 (the "1934 Act") after the date of this Agreement which is
or is deemed to be incorporated by reference in the Registration Statement or
the Prospectus, as the case may be.

     The Company understands that the Underwriters propose to make a public
offering of the Securities as soon as the Representative deems advisable after
this Agreement has been executed and delivered.

                                       2


     Section 1.  Representations and Warranties.
                 ------------------------------

     (a) The Company represents and warrants to each Underwriter as of the date
hereof (such date being hereinafter referred to as the "Representation Date")
and as of the Closing Time referred to in Section 2 as follows:

          (i) Compliance with Registration Requirements.  The Company meets the
              -----------------------------------------
     requirements for use of Form S-3 under the 1933 Act and the 1933 Act
     Regulations.  Each of the Original Registration Statement and any Rule
     462(b) Registration Statement and the Base Prospectus, at the respective
     times the Original Registration Statement, any Rule 462(b) Registration
     Statement and any post-effective amendments thereto became effective and as
     of the Representation Date, complied and comply in all material respects
     with the requirements of the 1933 Act and the 1933 Act Regulations

     the Representation Date do not contain an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or

     suspending the effectiveness of the Original Registration Statement or any
     Rule 462(b) Registration Statement has been issued under the 1933 Act and
     no proceedings for that purpose have been instituted or are pending or, to
     the knowledge of the Company, are contemplated by the Commission, and any
     request on the part of the Commission for additional information has been
     complied with.  The Prospectus, at the Representation Date (unless the term
     "Prospectus" refers to a prospectus which has been provided to the
     Underwriters by the Company for use in connection with the offering of the
     Securities which differs from the Prospectus filed with the Commission
     pursuant to Rule 424(b) of the 1933 Act Regulations, in which case at the
     time it is first provided to the Underwriters for such use) and at the
     Closing Time referred to in Section 2 hereof, does not and will not include
     an untrue statement of a material fact or omit to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading; provided,

     however, that the representations and warranties in this subsection (i)
     -------
     shall not apply to statements in or omissions from the Registration
     Statement or Prospectus made in reliance upon and in conformity with
     information furnished to the Company in writing by any Underwriter through
     Merrill Lynch expressly for use in the Registration Statement or the
     Prospectus or the information contained in any Statement of Eligibility and
     Qualification of a trustee under the Trust Indenture Act of 1939, as
     amended (the "1939 Act") filed as an exhibit to the Registration Statement
     (a "Form T-1").  For purposes of this Section 1(a), all references to the
     Registration Statement, any post-effective amendments thereto and the
     Prospectus shall be deemed to include, without limitation, any
     electronically transmitted copies thereof filed with the Commission
     pursuant to its Electronic Data Gathering, Analysis, and Retrieval system
     ("EDGAR").

          (ii) Incorporated Documents.  The documents incorporated or deemed to
               ----------------------

     with the Commission, complied and will comply in all material respects with
     the requirements of the 1934 Act and the rules and regulations of the
     Commission thereunder (the "1934 Act Regulations"), and, when read together
     and with the other information in the Prospectus, at the respective times

     and guidelines with respect to pro forma financial statements and have been
     properly compiled on the bases described therein, and the assumptions used

     are appropriate to give effect to the transactions and circumstances
     referred to therein; and the Company's ratios of earnings to fixed charges
     included in the Prospectus under the caption "Ratio of Earnings to Fixed
     Charges" and in Exhibit 12 to the Registration Statement have been
     calculated in compliance with Item 503(d) of Regulation S-K of the
     Commission.

     (a)  On the basis of the representations and warranties herein contained
and subject to the terms and conditions herein set forth, the Company agrees to
sell to each Underwriter,

                                       7


severally and not jointly, and each Underwriter, severally and not jointly,
agrees to purchase from the Company, at $______ per share, the number of Initial
Securities set forth in Schedule A opposite the name of such Underwriter plus
any additional number of Initial Securities which such Underwriter may become
obligated to purchase pursuant to the provisions of Section 10 hereof.

     In addition, on the basis of the representations and warranties herein
contained and subject to the terms and conditions herein set forth, the Company
hereby grants an option to the Underwriters, severally and not jointly, to
purchase up to an additional 525,000 shares of Common Stock at the price per
share set forth in paragraph (a) above.  The option hereby granted will expire
30 days after the Representation Date, and may be exercised in whole or in part
from time to time only for the purpose of covering over-allotments which may be
made in connection with the offering and distribution of the Initial Securities
upon notice by the Representative to the Company setting forth the number of
Option Securities as to which the several Underwriters are then exercising the
option and the time and date of payment and delivery for such Option Securities.
Any such time and date of delivery (a "Date of Delivery") shall be determined by
the Representative, but shall not be later than seven full business days after
the exercise of said option, nor in any event prior to Closing Time, as
hereinafter defined, unless otherwise agreed upon by the Representative and the
Company. .  If the option is exercised as to all or any portion of the Option
Securities, each of the Underwriters, acting severally and not jointly, will
purchase that proportion of the total number of Option Securities then being
purchased which the number of Initial Securities set forth in Schedule A
opposite the name of such Underwriter bears to the total number of Initial
Securities (except as otherwise provided in the Pricing Agreement), subject in
each case to such adjustments as the Representative in its discretion shall make
to eliminate any sales or purchases of fractional shares.

     (b)  Payment of the purchase price for, and delivery of certificates for,
the Initial Securities shall be made at the office of Latham & Watkins, 633 West
Fifth Street, Suite 4000, Los Angeles, California 90071-2007, or at such other
place as shall be agreed upon by the Representative and the Company, at 7:00
A.M., Los Angeles time, on May 14, 2001, or such other time not later than ten
business days after such date as shall be agreed upon by the Representative and
the Company (such time and date of payment and delivery being herein called
"Closing Time").  In addition, in the event that any or all of the Option
Securities are purchased by the Underwriters, payment of the purchase price for
and delivery of certificates for such Option Securities shall be made at the
above-mentioned office of Latham & Watkins, or at such other place as shall be
mutually agreed upon by the Representative and the Company, on each Date of
Delivery as specified in the notice from the Representative to the Company.
Payment shall be made to the Company by wire transfer of immediately available
funds to a bank account designated by the Company against delivery to the
Representative for the respective accounts of the Underwriters of certificates
for the Securities to be purchased by them. Certificates for the Initial
Securities and the Option Securities, if any, shall be in such denominations and
registered in such names as the Representative may request in writing at least
one business day before Closing Time or the relevant Date of Delivery, as the
case may be.  It is understood that each Underwriter has authorized the
Representative, for its account, to accept delivery of, receipt for, and make
payment of the purchase price for, the Initial Securities and the Option
Securities, if any, which it has agreed to purchase.  Merrill Lynch,
individually and not as representative of the Underwriters, may (but shall not
be obligated to) make payment of the

purchase price for the Initial Securities or the Option Securities, if any, to
be purchased by any Underwriter whose check has not been received by Closing
Time, but such payment shall not relieve such Underwriter from its obligations
hereunder. The certificates for the Initial Securities and the Option
Securities, if any, will be made available for examination and packaging by the
Representative not later than 10:00 A.M. on the last business day prior to

     exemption from qualification of the Securities under state securities or
     Blue Sky laws or the initiation of any proceedings for that purpose.  The
     Company will make every reasonable effort to prevent the issuance by the
     Commission of any stop order and, if any such stop order is issued, to
     obtain the lifting thereof at the earliest possible moment.  The Company
     will provide the Underwriters with copies of the form of Prospectus, in

     which the Company proposes for use by the Underwriters in connection with

     the Commission pursuant to Rule 424(b) of the 1933 Act Regulations, whether
     or not such revised prospectus is required to be filed pursuant to Rule
     424(b) of the 1933 Act Regulations or any abbreviated term sheet prepared
     in reliance on Rule 434 of the 1933 Act Regulations), will furnish the
     Representative with copies of any such amendment or supplement a reasonable

               -----------------------------------
     the Representative as many signed copies of the Registration Statement as
     originally filed and of each amendment thereto (including exhibits filed
     therewith and documents incorporated or deemed to be incorporated by
     reference therein) as the Representative may reasonably request and will
     also deliver to the Representative as many conformed copies of the

     may reasonably request for the purposes contemplated by the 1933 Act or the
     1934 Act or the respective applicable rules and regulations of the
     Commission thereunder.

               -----------------------------------------

     statement of a material fact or omit to state a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     existing at the time it is delivered to a purchaser, not misleading, and
     the Company will furnish to the Underwriters a reasonable number of copies
     of such amendment or supplement.

     provided, however, that the Company shall not be obligated to file any
     general consent to service of process or to qualify as a foreign
     corporation in any jurisdiction in which it is not so qualified.  In each
     jurisdiction in which the Securities shall have been so qualified, the
     Company will file such statements and reports as may be required by laws of
     such jurisdiction to continue such qualification in effect for as long as
     may be required for the distribution of the Securities.

          (g)  Earnings Statement.  The Company will make generally available to
               ------------------
     its security holders as soon as practicable, but not later than 60 days
     after the close of the period covered thereby, an earnings statement (in
     form complying with the provisions of Rule 158 of the 1933 Act Regulations)
     covering the twelve month period beginning not later than the first day of

     Regulations or as the Representative and the Company deem appropriate, and
     will file or transmit for filing with the Commission in accordance with
     Rule 424(b) of the 1933 Act Regulations copies of the Prospectus (including
     such Prospectus Supplement).

               pledge, lien, or claim.

                    (vi)  The execution and delivery of this Agreement has been
               duly and validly authorized by all necessary corporate action on
               the part of the Company under its charter and bylaws and the
               Maryland General Corporation Law. This Agreement has been duly
               executed and delivered by the Company.

                                       13


                    (vii)  The Common Stock conforms to the description thereof
               contained in the Prospectus and the form of certificate used to
               evidence the Securities is in due and proper form.

                    (viii) The issuance and sale of the Securities by the
               Company and the compliance by the Company with the provisions of
               this Agreement and the consummation of the transactions
               contemplated hereby, will not result in any violation of the
               provisions of the charter or bylaws of the Company.

                    (ix)   No authorization, approval, consent, decree or order
               of any court or governmental authority or agency is required
               under the Maryland General Corporation Law for the consummation
               by the Company of the transactions contemplated by this Agreement
               or in connection with the sale of the Securities hereunder,
               except such as may have been obtained or rendered, as the case
               may be.

                    (x)    The statements set forth in the Prospectus Supplement
               under the caption "Recent and Proposed Charter Amendments,"
               insofar as such statements purport to summarize certain
               provisions of the documents referred to therein, fairly summarize
               such provisions in all material respects, and insofar as such
               statements constitute matters of law, summaries of legal matters
               or legal conclusions, are correct in all material respects.

               In rendering its opinion, Ballard Spahr Andrews & Ingersoll, LLP
          shall state that each of Sidley Austin Brown & Wood LLP, in rendering
          its opinion pursuant to Section 5(b)(5), and Latham & Watkins, in
          rendering its opinion pursuant to Section 5(b)(1), may rely upon such
          opinion as to matters arising under the laws of the State of Maryland.

               (4)         The favorable opinion, dated as of Closing Time, of
          Edward J. Henning, General Counsel of the Company, in form and scope
          satisfactory to counsel for the Underwriters, to the effect that:

                    (i)    To the best of such counsel's knowledge and
               information, the Company is duly qualified as a foreign
               corporation to transact business and is in good standing in each
               jurisdiction in which its ownership or lease of substantial
               properties or the conduct of its business requires such
               qualification, except where the failure to so qualify would not
               have a material adverse effect on the condition, financial or
               otherwise, or the earnings, business affairs or business
               prospects of the Company and its subsidiaries considered as one
               enterprise.

                    (ii)   To the best of such counsel's knowledge and
               information, each Significant Subsidiary of the Company is duly
               qualified as a foreign corporation to transact business and is in
               good standing in each jurisdiction in which its ownership or
               lease of substantial properties or the

                                       14


               conduct of its business requires such qualification, except where
               the failure to so qualify and be in good standing would not have
               a material adverse effect on the condition, financial or
               otherwise, or the earnings, business affairs or business
               prospects of the Company and its subsidiaries considered as one
               enterprise.

                    (iii)  To the best of such counsel's knowledge and
               information, no material default exists in the due performance or
               observance by the Company or any of its subsidiaries of any
               obligation, agreement, covenant or condition contained in any
               contract, indenture, mortgage, loan agreement, note, lease or
               other instrument described or referred to in the Registration
               Statement or filed as an exhibit thereto or incorporated by
               reference therein which would have a material adverse effect on
               the condition, financial or otherwise, or in the earnings,
               business affairs or business prospects of the Company and its
               subsidiaries considered as one enterprise.

                    (iv)   To the best of such counsel's knowledge and
               information, there are no contracts, indentures, mortgages, loan
               agreements, notes, leases or other instruments or documents
               required to be described or referred to in the Registration
               Statement or to be filed as exhibits thereto other than those
               described or referred to therein or filed or incorporated by
               reference as exhibits thereto and the descriptions thereof or
               references thereto are correct.

                    (v)    The authorized, issued and outstanding capital stock
               of the Company is as set forth in the Prospectus under
               "Capitalization" (except for subsequent issuances, if any,
               pursuant to reservations, agreements, dividend reinvestment plans
               or employee or director stock plans referred to in the
               Prospectus), and the shares of issued and outstanding Common
               Stock and Preferred Stock have been duly authorized and validly
               issued and are fully paid and non-assessable.

                    (vi)   To the best of such counsel's knowledge, there are no
               legal or governmental proceedings pending or threatened which are
               required to be disclosed in the Prospectus.

                    (vii)  The issue and sale of the Securities and the
               compliance by the Company with the provisions of this Agreement
               and the consummation of the transactions contemplated herein will
               not, to the best of such counsel's knowledge, result in any
               material violation of any order applicable to the Company of any
               court or governmental agency or body having jurisdiction over the
               Company or any of its subsidiaries or any of their properties.

               (5)         The favorable opinion, dated as of Closing Time, of
          Sidley Austin Brown & Wood LLP, counsel for the Underwriters, with
          respect to the matters set forth in paragraph (ii) of Exhibit A hereto
          and in subparagraphs (i), (iv), (vi) and

                                       15


          (vii) of subsection (b)(3) of this Section. In rendering such opinion,
          Sidley Austin Brown & Wood LLP may rely upon the opinion of Ballard
          Spahr Andrews & Ingersoll, LLP, rendered pursuant to Section 5(b)(3),
          as to matters arising under the laws of the State of Maryland.

               (6)  In giving their opinions required by subsections (b)(1) and
          (b)(5), respectively, of this Section, Latham & Watkins and Sidley
          Austin Brown & Wood LLP shall each additionally state that nothing has
          come to their attention that would cause them to believe that the
          Registration Statement, at the time it became effective, contained an
          untrue statement of a material fact or omitted to state a material
          fact required to be stated therein or necessary to make the statements
          therein not misleading or that the Prospectus, at the Representation
          Date (unless the term "Prospectus" refers to a prospectus which has
          been provided to the Underwriters by the Company for use in connection
          with the offering of the Securities which differs from the Prospectus
          on file at the Commission at the Representation Date, in which case at
          the time it is first provided to the Underwriters for such use) or at
          Closing Time, included or includes an untrue statement of a material
          fact or omitted or omits to state a material fact necessary in order
          to make the statements therein, in the light of the circumstances
          under which they were made, not misleading; it being understood that
          such counsel shall express no opinion with respect to the financial
          statements, schedules and other financial data in the Registration
          Statement or the Prospectus. In giving their opinions, Latham &
          Watkins and Sidley Austin Brown & Wood LLP may rely, to the extent
          recited therein, (A) as to all matters of fact, upon certificates and
          written statements of officers of the Company and (B) as to the
          qualification and good standing of the Company and each Significant
          Subsidiary to do business in any state or jurisdiction, upon
          certificates of appropriate government officials.

          (c)  Officers' Certificate. At Closing Time there shall not have been,
               ---------------------
     since the date hereof or since the respective dates as of which information
     is given in the Registration Statement and the Prospectus, any material
     adverse change in the condition, financial or otherwise, or in the
     earnings, business affairs or business prospects of the Company and its
     subsidiaries considered as one enterprise, whether or not arising in the
     ordinary course of business, and the Representative shall have received a
     certificate of the President or a Vice President of the Company and of the
     chief financial or chief accounting officer of the Company, dated as of
     Closing Time, to the effect that (i) there has been no such material
     adverse change, (ii) the representations and warranties in Section 1 hereof
     are true and correct with the same force and effect as though expressly
     made at and as of Closing Time, (iii) the Company has performed or complied
     with all agreements and satisfied all conditions on its part to be
     performed or satisfied at or prior to Closing Time, and (iv) no stop order
     suspending the effectiveness of the Registration Statement has been issued
     and no proceedings for that purpose have been initiated or, to the best
     knowledge and information of such officer, threatened by the Commission. As
     used in this Section 5(c), the term "Prospectus" means the Prospectus in
     the form first used to confirm sales of the Securities.

                                       16


          (d)  Accountant's Comfort Letter. At the time of the execution of this
               ---------------------------
     Agreement, the Representative shall have received from Arthur Andersen LLP
     a letter, dated such date, in form and substance satisfactory to the

     Time, to the effect that they reaffirm the statements made in the letter
     furnished pursuant to subsection (d) of this Section, except that the
     specified date referred to therein shall be a date not more than three
     business days prior to Closing Time.

               -------
     listed, subject to notice of issuance, on the New York Stock Exchange.

          (g)  Lock-up Agreements. The Representative shall have received an

     Agreement.

          (h)  Additional Documents. At Closing Time and at each Date of
               --------------------
     Delivery, if any, counsel for the Underwriters shall have been furnished
     with such documents and opinions as they may reasonably require for the
     purpose of enabling them to pass upon the issuance and sale of the

     contained herein and the statements in any certificates furnished by the
     Company hereunder shall be true and correct as of each Date of Delivery,
     and subject to the following further conditions:

               (1)  The Representative shall have received:

     Section 6.  Indemnification.
                 ---------------

     (a) Indemnification of the Underwriters.  The Company agrees to indemnify
         -----------------------------------
and hold harmless each Underwriter and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act, as follows:

                                       18


          (i)    against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), or any omission or alleged omission therefrom
     of a material fact required to be stated therein or necessary to make the
     statements therein not misleading or arising out of any untrue statement or
     alleged untrue statement of a material fact contained in any preliminary
     prospectus, any preliminary prospectus supplement or the Prospectus (or any
     amendment or supplement thereto) or the omission or alleged omission
     therefrom of a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading;

          (ii)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Company; and

          (iii)  against any and all expense whatsoever, as incurred (including,
     subject to Section 6(c) hereof, the fees and disbursements of counsel
     chosen by Merrill Lynch), reasonably incurred in investigating, preparing
     or defending against any litigation, or any investigation or proceeding by
     any governmental agency or body, commenced or threatened, or any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, to the extent that any such expense
     is not paid under (i) or (ii) above;

provided, however, that (A) this indemnity agreement shall not apply to any
- --------  -------
loss, liability, claim, damage or expense to the extent arising out of any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with written information furnished to the
Company by any Underwriter through Merrill Lynch expressly for use in the
Registration Statement (or any amendment thereto) or any preliminary prospectus,
preliminary prospectus supplement or the Prospectus (or any amendment or
supplement thereto), and (B) with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus or
preliminary prospectus supplement, this indemnity agreement shall not inure to
the benefit of the Underwriters (or to the benefit of any person controlling an
Underwriter within the meaning of Section 15 of the 1933 Act) to the extent that
any such loss, liability, claim, damage or expense of the Underwriters or any
person controlling the Underwriters' results from the fact that the Underwriters
sold Securities to a person to whom it shall be established there was not sent
or given by the Underwriters or on the Underwriters' behalf at or prior to the
written confirmation of the sale of such Securities to such person, a copy of
the Prospectus (as then amended or supplemented), if required by law to have
been so delivered, and if the Prospectus (as so amended or supplemented) would
have cured the defect giving rise to such loss, liability, claim, damage or
expense and provided that the Company shall have met its obligation pursuant to
this Agreement to provide the Underwriters with such Prospectus (as so amended
or supplemented).

                                       19


     (b)  Indemnification of Company, Directors and Officers.  Each Underwriter
          --------------------------------------------------
severally agrees to indemnify and hold harmless the Company, its directors, each
of its officers who signed the Registration Statement, and each person, if any,
who controls the Company within the meaning of Section 15 of the 1933 Act
against any and all loss, liability, claim, damage and expense described in the
indemnity contained in subsection (a) of this Section, as incurred, but only
with respect to untrue statements or omissions, or alleged untrue statements or
omissions, made in the Registration Statement (or any amendment thereto) or any
preliminary prospectus, preliminary prospectus supplement or the Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by any Underwriter through Merrill
Lynch expressly for use in the Registration Statement (or any amendment thereto)
or such preliminary prospectus, preliminary prospectus supplement or the
Prospectus (or any amendment or supplement thereto).

     (c)  Actions Against Parties; Notification.  Each indemnified party shall
          -------------------------------------
give written notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it is
not materially prejudiced as a result thereof and in any event shall not relieve
it from any liability which it may have otherwise than on account of this
indemnity agreement.  In the case of parties indemnified pursuant to Section
6(a) above, counsel to the indemnified parties shall be selected by the
Representative, and, in the case of parties indemnified pursuant to Section 6(b)
above, counsel to the indemnified parties shall be selected by the Company.  An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
        --------  -------
(except with the consent of the indemnified party) also be counsel to the
indemnified party.  In no event shall the indemnifying parties be liable for
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.  No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 6 or Section 7 hereof (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

     (d)  Settlement without Consent if Failure to Reimburse.  If at any time an
          --------------------------------------------------
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 6(a)(ii) effected without its written consent if (i) such settlement is
entered into more than 45 days after receipt by such indemnifying party of the
aforesaid request, (ii) such indemnifying party shall have received notice of
the terms of such settlement at least 30 days prior to such settlement being
entered into and (iii) such indemnifying

                                       20


party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement.

     (e)   EDGAR.  For purposes of this Section 6, all references to the
           -----
Registration Statement, any preliminary prospectus, preliminary prospectus
supplement or the Prospectus, or any amendment or supplement to any of the
foregoing, shall be deemed to include, without limitation, any electronically
transmitted copies thereof filed with the Commission pursuant to EDGAR.

     Section 7.  Contribution.  If the indemnification provided for in Section 6
                 ------------
hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company, on the one
hand, and the Underwriters, on the other hand, from the offering of the
Securities pursuant to this Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Company, on the one hand, and of the
Underwriters, on the other hand, in connection with the statements or omissions
which resulted in such losses, liabilities, claims, damages or expenses, as well
as any other relevant equitable considerations.

     The relative benefits received by the Company, on the one hand, and the
Underwriters, on the other hand, in connection with the offering of the
Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total underwriting discount received by the Underwriters, in
each case as set forth on the cover of the Prospectus (or, if Rule 434 is used,
the corresponding location on the Term Sheet) bear to the aggregate public
offering price of the Securities as set forth on such cover (or corresponding
location on the Term Sheet, as the case may be).

     The relative fault of the Company, on the one hand, and the Underwriters,
on the other hand, shall be determined by reference to, among other things,
whether any such untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Underwriters and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.

     The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this Section 7.  The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 7 shall be deemed to
include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by

                                       21


any governmental agency or body, commenced or threatened, or any claim
whatsoever based upon any such untrue or alleged untrue statement or omission or
alleged omission.

     Notwithstanding the provisions of this Section 7, no Underwriter shall not
be required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it were offered exceeds the amount
of any damages which such Underwriter has otherwise been required to pay by
reason of any such untrue or alleged untrue statement or omission or alleged
omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement, and each person, if any, who controls the Company within
the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall
have the same rights to contribution as the Company.

     Section 8.  Representations, Warranties and Agreements to Survive Delivery.
                 --------------------------------------------------------------
All representations, warranties and agreements contained in this Agreement, or
contained in certificates of officers of the Company submitted pursuant hereto
or thereto, shall remain operative and in full force and effect, regardless of
any investigation made by or on behalf of any Underwriter or any controlling
person, or by or on behalf of the Company, and shall survive delivery of the
Securities to the Underwriters.

     Section 9.  Termination of Agreement.
                 ------------------------

     (a)  The Representative may terminate this Agreement, by notice to the
Company, at any time at or prior to Closing Time (i) if there has been, since
the date of this Agreement or since the respective dates as of which information
is given in the Prospectus, any material adverse change in the condition,
financial or otherwise, or in the earnings, business affairs or business
prospects of the Company and its subsidiaries considered as one enterprise,
whether or not arising in the ordinary course of business, (ii) if there has
occurred any material adverse change in the financial markets in the United
States, any outbreak of hostilities or other calamity or crisis or change or
development involving a prospective change in national or international
political, financial or economic conditions, in each case the effect of which on
the financial markets of the United States is such as to make it, in the
judgment of the Representative, impracticable to market the Securities or
enforce contracts for the sale of the Securities, or (iii) if trading in the
securities of the Company has been suspended by the Commission, or if trading
generally on either the American Stock Exchange or the New York Stock Exchange
or in the NASDAQ National Market has been suspended, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices for securities
have been required, by either of said Exchanges or by order of the Commission,
the NASD or any other governmental authority, or if a banking moratorium has
been declared by either federal, New York, Maryland or

                                       22


California authorities. As used in this Section 9(a), the term "Prospectus"
means the Prospectus in the form first used to confirm sales of the Securities.

     (b)  If this Agreement is terminated pursuant to this Section, such
termination shall be without liability of any party to any other party except as
provided in Section 4 hereof.  Notwithstanding any such termination, the
provisions of Sections 4, 6, 7 and 8 shall remain in effect.

     Section 10.  Default by One or More of the Underwriters.  If one or more of
                  ------------------------------------------
the Underwriters shall fail at Closing Time or a Date of Delivery to purchase
the Securities which it or they are obligated to purchase under this Agreement
(the "Defaulted Securities"), the Representative shall have the right, within 24
hours thereafter, to make arrangements for one or more of the non-defaulting
Underwriters, or any other underwriters, to purchase all, but not less than all,
of the Defaulted Securities in such amounts as may be agreed upon and upon the
terms herein set forth; if, however, the Representative shall not have completed
such arrangements within such 24-hour period, then:

     (a)  if the number of Defaulted Securities does not exceed 10% of the
number of Securities to be purchased on such date, each of the non-defaulting
Underwriters shall be obligated, severally and not jointly, to purchase the full
amount thereof in the proportions that their respective underwriting obligations
hereunder bear to the underwriting obligations of all non-defaulting
Underwriters, or

     (b)  if the number of Defaulted Securities exceeds 10% of the number of
Securities to be purchased on such date, this Agreement or, with respect to any
Date of Delivery which occurs after the Closing Time, the obligation of the
Underwriters to purchase and of the Company to sell the Option Securities to be
purchased and sold on such Date of Delivery shall terminate without liability on
the part of any non-defaulting Underwriter.

     No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

     In the event of any such default which does not result in a termination of
this Agreement or in the case of a Date of Delivery which is after the Closing
Time, which does not result in a termination of the obligation of the
Underwriters to purchase and the Company to sell the relevant Option Securities,
as the case may be, either the Representative or the Company shall have the
right to postpone Closing Time or the relevant Date of Delivery, as the case may
be, for a period not exceeding seven days in order to effect any required
changes in the Registration Statement or Prospectus or in any other documents or
arrangements.  As used herein, the term "Underwriter" includes any person
substituted for an Underwriter under this Section 10.

     Section 11.  Notices.  All notices and other communications hereunder shall
                  -------
be in writing and shall be deemed to have been duly given if mailed or
transmitted by any standard form of written telecommunication.  Notices to the
Underwriters shall be directed to the Representative at Merrill Lynch & Co.,
10877 Wilshire Boulevard, Suite 1900, Los Angeles, CA 90024, Attention: James F.
Flaherty III, Managing Director, and notices to the Company shall be

                                       23


directed to it at 4675 MacArthur Court, 9th Floor, Newport Beach, California

a copy to Pamela B. Kelly, Esq. at Latham & Watkins, 633 West Fifth Street,
Suite 4000, Los Angeles, California 90071.

     Section 12.  Parties.  This Agreement shall inure to the benefit of and be
                  -------
binding upon the Underwriters and the Company and their respective successors.
Nothing expressed or mentioned in this Agreement is intended or shall be
construed to give any person, firm or corporation, other than the Underwriters
and the Company and their respective successors and the controlling persons and
the officers and directors referred to in Sections 6 and 7 hereof and their
heirs and legal representatives any legal or equitable right, remedy or claim
under or in respect of this Agreement or any provision herein contained.  This
Agreement and all conditions and provisions hereof are intended to be for the
sole and exclusive benefit of the Underwriters and the Company and their
respective successors, and said controlling persons and said officers and
directors and their heirs and legal representatives, and for the benefit of no
other person, firm or corporation.  No purchaser of Securities from any
Underwriter shall be deemed to be a successor merely by reason of such purchase.

     Section 13.  Governing Law and Time.  This Agreement shall be governed by
                  ----------------------
and construed in accordance with the laws of the State of California applicable
to agreements made and to be performed in such State.  Unless stated otherwise,
all specified times of day refer to New York City time.
