Dear Sirs:

HCP, Inc., a Maryland corporation (the “Company”), confirms its agreement with you (the “Underwriter” or “you”), with respect to the issue and sale by the Company and the purchase by you of 9,000,000 shares of Common Stock, par value $1.00 per share, of the Company (the “Common Stock”) and with respect to the grant by the Company to you of the option described in Section 2(b) hereof to purchase all or any part of 1,350,000 additional shares of Common Stock. The aforesaid 9,000,000 shares of Common Stock (the “Initial Securities”) to be purchased by you and all or any part of the 1,350,000 shares of Common Stock subject to the option described in Section 2(b) hereof (the “Option Securities”) are collectively hereinafter called the “Securities.”

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-137225), which registration statement became effective upon filing under Rule 462(e) of the rules and regulations of the Commission (the “1933 Act Regulations”) under the Securities Act of 1933, as amended (the “1933 Act”). Such registration statement covers the registration of the Securities (among others) under the 1933 Act. Such registration statement, in the form in which it became effective, as amended through the date hereof, including the information deemed pursuant to Rule 430B under the 1933 Act Regulations to be part of the registration statement at the time of its effectiveness (“Rule 430B Information”) and all documents incorporated or deemed to be incorporated by reference therein through the date hereof, 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(k)

hereof) relating to the Securities and the prospectus dated September 8, 2006 (the “Base Prospectus”), 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 you 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 you 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, the Base Prospectus 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, the Base Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, the Base Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), after the date of this Agreement which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus, as the case may be.

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

At or prior to the time when sales of the Securities were first made (such time, the “Time of Sale”), the Company had prepared the following information (collectively the “Time of Sale Information”): the Base Prospectus, the information included in Exhibit C hereto and each “free-writing prospectus” (as defined pursuant to Rule 405 of the 1933 Act Regulations) listed on Exhibit B hereto.

To the best knowledge of the Company, the instruments securing its real estate mortgage loans in favor of the Company and its subsidiaries create valid liens upon the real properties described in such instruments enjoying the priorities intended, subject only to exceptions to title which have no material adverse effect on the value of such interests in relation to the Company and its subsidiaries considered as one enterprise; and at the time the Company and its subsidiaries first acquired an interest in such real estate mortgage loans, the Company and its subsidiaries obtained satisfactory confirmations (consisting of policies of title insurance or commitments or binders therefor, opinions of counsel based upon the examination of abstracts, or other evidence deemed appropriate by the Company under the circumstances).

(xix)                           Investment Company Act. The Company is not required to be registered, and after giving effect to the offering contemplated hereby and the application of the

(xxi)                           Disclosure Controls and Procedures. The Company has established and maintains “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the 1934 Act) that (i) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s Chief Executive Officer and its Chief Financial Officer by others within those entities, particularly during the periods in which the filings made by the Company with the Commission which it may make under Section 13(a), 13(c) or 15(d) of the 1934 Act are being prepared, (ii) have been evaluated for effectiveness as of the end of the Company’s most recent fiscal year and (iii) are effective at a reasonable assurance level to perform the functions for which they were established.

(xxii)                        Internal Control. The Company has established and maintains “internal control over financial reporting” (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the 1934 Act) that (i) are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and (ii) have been evaluated by the management of the Company (including the Company’s Chief Executive Officer and Chief Financial Officer) for effectiveness as of the end of the Company’s most recent fiscal year. In addition, not later than the date of the filing with the Commission of the Company’s most recent Annual Report on Form 10-K, each of the accountants and the audit committee of the board of directors of the Company had been advised of (x) all significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information and (y) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting. Since the date of the most recent evaluation of such controls and procedures, there have been no changes in the Company’s internal control over financial reporting or in other factors that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

(xxiii)                     Status Under the 1933 Act. The Company is not an “ineligible issuer” and is a “well-known seasoned issuer,” in each case as defined in the 1933 Act, in each case at the times specified in the 1933 Act in connection with the offering the Securities.

(xxiv)                    Acquisition. To the knowledge of the Company, the representations and warranties contained in paragraph (vii) of this Section 1 are true and correct with respect to the financial statements and any supporting schedules of CNL and its consolidated

9

subsidiaries, CNL Retirement Corp. (the “Advisor”) and its consolidated subsidiaries and SEUSA and its consolidated subsidiaries included or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus; except where the failure to be so true and correct would not, individually or in the aggregate, reasonably be expected to 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.

The Company will make every reasonable effort to prevent the issuance by the Commission of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of the Base Prospectus or the Prospectus or suspending any such qualification or exemption of the Securities and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment. The Company will provide you with copies of the form of Prospectus and each Issuer Free Writing Prospectus, in such numbers as you may reasonably request, and file or transmit for filing with the Commission such Prospectus and each Issuer Free Writing Prospectus to the extent required by Rule 433 of the 1933 Act Regulations in accordance with Rule 424(b) of the 1933 Act Regulations by the close of business in New York on the second business day immediately succeeding the date hereof.

11

(b)                                 Filing of Amendments. During the Prospectus Delivery Period, the Company will give you notice of its intention to file or prepare any amendment to the Registration Statement or any amendment or supplement to the Prospectus (including any revised prospectus which the Company proposes for use by you in connection with the offering of the Securities that differs from the prospectus filed 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), will furnish you with copies of any such amendment or supplement a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file any such amendment or supplement or use any such prospectus to which you or your counsel shall reasonably object.

(c)                                  Issuer Free Writing Prospectuses. Before making, preparing, using, authorizing, approving, referring to or filing any Issuer Free Writing Prospectus related to the Securities, whether before or after the time that the Registration Statement becomes effective, the Company will furnish to you or your counsel a copy of the proposed Issuer Free Writing Prospectus for review and will not make, prepare, use, authorize, approve, refer to or file any such Issuer Free Writing Prospectus to which you reasonably object.

(f)                                    Continued Compliance with Securities Laws. If, at any time during the Prospectus Delivery Period, any event shall occur as a result of which it is necessary, in the opinion of your counsel or counsel for the Company, to amend or supplement the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, the Company will forthwith amend or supplement the Prospectus (in form and substance satisfactory to your counsel) so that, as so amended or supplemented, the Prospectus will not contain 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 existing at the time it is delivered to a purchaser, not misleading, and the Company will furnish to you a reasonable number of copies of such amendment or supplement. If, in accordance with the preceding sentence, it shall be necessary to amend or supplement the Prospectus at any time subsequent to the expiration of nine months after the first date of the public offering of the Securities, you shall bear the expense of preparing, filing and furnishing any such amendment or supplement. If at any time following issuance of an Issuer Free Writing Prospectus through Closing Time there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the

12

Registration Statement, the Prospectus or the Time of Sale Information or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Company will promptly notify you and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(g)                                 Time of Sale Information. If at any time prior to Closing Time (A) any event shall occur or condition shall exist as a result of which the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances, not misleading or (B) it is necessary to amend or supplement the Time of Sale Information to comply with law, the Company will immediately notify you thereof and forthwith prepare and, subject to paragraph (c) above, file with the Commission (to the extent required) and furnish to you and to such dealers as you may designate, such amendments or supplements to the Time of Sale Information as may be necessary so that the statements in the Time of Sale Information as so amended or supplemented will not, in the light of the circumstances, be misleading or so that the Time of Sale Information will comply with law.

(h)                                 Blue Sky Qualifications. The Company will endeavor, in cooperation with you, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions of the United States as you may designate; 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.

The Company will make generally available to its security holders as soon as practicable, but not later than 90 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 the Company’s fiscal quarter next following the “effective date” (as defined in said Rule 158) of the Registration Statement.

(j)                                     Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner to be specified in the Prospectus Supplement under “Use of Proceeds.”

(k)                                  Preparation of Prospectus Supplement. Immediately following the execution of this Agreement, the Company will prepare a prospectus supplement, dated the date hereof (the “Prospectus Supplement”), containing the terms of the Securities, the plan of distribution thereof and such other information as may be required by the 1933 Act or the 1933 Act Regulations or as you 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).

13

(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 you), 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 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 you expressly for use in the Registration Statement (or any amendment thereto) or the Prospectus (or any amendment or supplement thereto), or any Issuer Free Writing Prospectus or any Time of Sale Information, or made in reliance upon the Trustee’s Form T-1 filed as an exhibit to the Registration Statement.

22

(b)                                 Indemnification of the Company, Directors and Officers. The Underwriter 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 or Section 20 of the 1934 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 the Prospectus (or any amendment or supplement thereto) or any Issuer Free Writing Prospectus  or any Time of Sale Information in reliance upon and in conformity with written information furnished to the Company by you expressly for use therein.

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

23

(e)                                  EDGAR. For purposes of this Section 6, all references to the Registration Statement, Issuer Free Writing Prospectus 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 you, 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 you, 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 you, 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 that the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Underwriter.

The relative fault of the Company, on the one hand, and you, 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 you and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriter 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 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, you shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by you were offered exceeds the amount of any damages which you have otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

24

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 the 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 the 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, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or any controlling person, or by or on behalf of the Company, and shall survive delivery of the Securities to the Underwriter.

Section 9. Termination.

(a)                                  The Underwriter may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (and, if any Option Securities are to be purchased on a Date of Delivery which occurs after the Closing Time, the Underwriter may terminate the obligation to purchase such Option Securities, by notice to the Company, at any time on or prior to such Date of Delivery) (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 or the Time of Sale Information, 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 Underwriter’s judgment, impracticable to market the Securities or enforce contracts for the sale of the Securities, (iii) if trading in any securities of the Company has been suspended by the Commission or a national securities exchange, or if trading generally on either the American Stock Exchange or the New York Stock Exchange or in the NASDAQ Global 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 the NASDAQ Global Market or by order of the Commission, the Financial Industry Regulatory Authority or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either federal, New York, Maryland or 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.

25

Notwithstanding any such termination, the provisions of Sections 4, 6, 7 and 8 shall remain in effect.

Section 10. Certain Agreements of the Underwriter. The Underwriter hereby represents and agrees that:

(a)                                  It has not and will not use, authorize use of, refer to, or participate in the plan for use of, any “free writing prospectus,” as defined in Rule 405 of the 1933 Act Regulations other than (i) a free writing prospectus that, solely as a result of use by the Underwriter would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433 of the 1933 Act Regulations, (ii) any Issuer Free Writing Prospectus listed on Exhibit C or prepared pursuant to Section 1(a)(iii) or Section 3(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by the Underwriter and approved in writing by the Company in advance of the use of such free writing prospectus.

(b)                                 It is not subject to any pending proceeding under Section 8A of the 1933 Act with respect to the offering (and will promptly notify the Company if any such proceeding against it is initiated during the Prospectus Delivery Period).
