(the “Underwriter”) as set forth in this underwriting agreement (this “Agreement”). Each of Ventas and the Operating Partnership are referred to herein sometimes individually as a “Ventas Entity” and together as the “Ventas Entities.”

The Selling Stockholders propose to sell, severally and not jointly, to the Underwriter an aggregate of 21,070,658 shares of the Issuer’s common stock, par value $0.25 per share (the “Securities”). The number of Securities that each Selling Stockholder is selling to the Underwriter is set forth opposite such Selling Stockholder’s name on Schedule A.

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Ventas Entities. The Ventas Entities, jointly and severally, represent and warrant to the Underwriter as of the date hereof, as of the Applicable Time referred to in Section 1(a)(iv) and as of the Closing Time referred to in Section 2(c), and agree with the Underwriter, as follows:

(i) Registration Statement. The Issuer has prepared and filed with the U.S. Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3 (File No. 333-174346), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of the Securities. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, at each time of effectiveness under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act, is called the “Registration Statement.” Any preliminary prospectus supplement that describes the Securities and the offering thereof and is used prior to the filing of the Prospectus is hereafter called, together with the Base Prospectus, a “preliminary prospectus.” The term “Prospectus” shall mean the final prospectus supplement relating to the Securities that is first filed pursuant to Rule 424(b) under the Securities Act after the date and time that this Agreement is executed and delivered by the parties hereto (the “Execution Time”), together with the Base Prospectus.

Any reference herein to the Registration Statement, the Base Prospectus, any preliminary prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act; any reference to any amendment or supplement to the Registration Statement, the Base Prospectus, any preliminary prospectus or the Prospectus shall be deemed to refer to and include any documents filed after the date of such Registration Statement, such Base Prospectus, any preliminary prospectus or Prospectus, as the case may be, under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), and incorporated by reference in such Registration Statement, such Base Prospectus, any preliminary prospectus or Prospectus, as the case may be.

(ii) Compliance with Registration Requirements. The Registration Statement has become effective upon filing with the Commission under the Securities Act. No stop order suspending the effectiveness of the Registration Statement is in effect, the Commission has not issued any order or notice preventing or suspending the use of the Registration Statement, any preliminary prospectus or the Prospectus and no proceedings for such purpose have been instituted or are pending or, to the knowledge of the Ventas Entities, are contemplated or threatened by the Commission.

Each of the preliminary prospectus, if any, and the Prospectus when filed complied in all material respects with the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at each time of effectiveness and at the date hereof, complied and will comply in all material respects with the Securities Act and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. The Prospectus, as amended or supplemented, as of its date, at the date hereof, at the time of any filing pursuant to Rule 424(b) under the Securities Act and at the Closing Time (as defined herein), did not and will not contain any 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. The representations and warranties set forth in the two immediately preceding sentences do not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, or the Prospectus, or any amendments or supplements thereto, made in reliance upon and in conformity with (A) information relating to the Underwriter furnished to Ventas in writing by the Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the Underwriter Information described as such in Section 6(c) hereof or (B) information relating to the Selling Stockholders furnished to Ventas in writing by any Selling Stockholder expressly for use therein, it being understood and agreed that the only such information furnished by the Selling Stockholders consists of the information described in Section 1(c)(vi) hereof. There is no contract or other document required to be described in the Prospectus or to be filed as an exhibit to the Registration Statement that has not been described or filed as required.

The documents incorporated by reference in the Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable. Any further documents so filed and incorporated by reference in the Prospectus or any further amendment or supplement thereto, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the Securities Act or the Exchange Act, as applicable.

(iii) Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto, if applicable, for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus) or determining compliance under Rule 405 of the Securities Act, and (iii) at the time the Issuer or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) under the Securities Act) made any offer relating to the Securities in reliance on the exemption of Rule 163 of the Securities Act, the Issuer was and is a “well-known seasoned issuer” as defined in Rule 405 of the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 of the Securities Act, and Ventas has not received from the Commission any notice pursuant to Rule 401(g)(2) of the Securities Act objecting to use of the automatic shelf registration statement form.

(iv) Disclosure Package. The term “Disclosure Package” shall mean (i) the Base Prospectus and the preliminary prospectus, if any, as amended or supplemented, (ii) the pricing information orally conveyed to prospective investors set forth on Annex A attached hereto (the “Pricing Information”) and (iii) any free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. As of the date and time of execution of this Agreement (the “Applicable Time”), the Disclosure Package did not 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 under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package made in reliance upon and in conformity with (A) information relating to the Underwriter furnished to Ventas in writing by the Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the Underwriter Information described as such in Section 6(c) hereof or (B) information relating to the Selling Stockholders furnished to Ventas in writing by any Selling Stockholder expressly for use therein, it being understood and agreed that the only such information furnished by the Selling Stockholders consists of the information described in Section 1(c)(vi) hereof.

(i) At the earliest time after the filing of the Registration Statement relating to the Securities that the Issuer or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the Securities Act) and (ii) at the time of the most recent amendment thereto, if applicable, for the purposes of (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus) determining compliance under Rule 405 of the Securities Act, the Issuer was not and is not an Ineligible Issuer (as defined in Rule 405 of the Securities Act), without taking account of any determination by the Commission pursuant to Rule 405 of the Securities Act that it is not necessary that the Issuer be considered an Ineligible Issuer.

(vi) Issuer Free Writing Prospectuses. Each issuer free writing prospectus as defined in Rule 433 of the Securities Act (each, an “Issuer Free Writing Prospectus”), as of its issue date and at all subsequent times through the completion of the offering of Securities under this Agreement or until any earlier date that the Issuer notified or notifies the Underwriter as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus 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 Registration Statement, the Issuer has promptly notified and shall promptly notify the Underwriter and has promptly amended or supplemented or shall promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus made in reliance upon and in conformity with (A) information relating to the Underwriter furnished in writing to the Issuer by the Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriter consists of the Underwriter Information described as such in Section 6(c) hereof or (B) information relating to the Selling Stockholders furnished to Ventas in writing by any Selling Stockholder expressly for use therein, it being understood and agreed that the only such information furnished by the Selling Stockholders consists of the Information described in Section 1(c)(vi) hereof.

All such Authorizations are valid and in full force and effect, and Ventas and each Subsidiary is in compliance with the terms and conditions of all such Authorizations and with the rules and regulations of the regulatory authorities having jurisdiction with respect to such Authorizations, except for any invalidity, failure to be in full force and effect or noncompliance with any Authorization that is not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect.

Ventas and each Subsidiary has good and marketable title in fee simple or a ground leasehold interest in all items of real property described as owned by them in Ventas’ filings with the Commission, except for properties capitalized under capital leases, and good and marketable title to all personal property owned by each of them, in each case free and clear of all Liens, except (i) for Liens described in each of the Disclosure Package and the Prospectus and (ii) to the extent that the failure to have such title or the presence of such Liens is not, individually or in the aggregate, reasonably likely to result in a Material Adverse Effect. Any real property and buildings held under lease by Ventas or any Subsidiary are held under valid, subsisting and enforceable leases, except to the extent that the failure to so hold such real property and buildings is not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect.

(xxii) Authorization, etc. of Leases. Each of Ventas’s and the Subsidiaries’ leases, including the Master Leases (as defined below), has been duly authorized by one or more of Ventas and its Subsidiaries, as applicable, and is a valid and binding agreement of Ventas and/or any such Subsidiary, and, to the knowledge of Ventas and/or any such Subsidiary, each other party thereto, enforceable in accordance with its terms, except as enforcement thereof may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general principles of equity and the discretion of the court before which any proceedings therefor may be brought and except, with respect to Ventas’s and the Subsidiaries’ leases (other than the Master Leases), as would not individually or in the aggregate, be reasonably likely to have a Material Adverse Effect. To the knowledge of any of the Ventas Entities, no lessee or sublessee of any portion of any of the properties owned or leased by Ventas and/or any Subsidiary is in default under its respective lease and there is no event that, but for the passage of time or the giving of notice or both, would constitute a default under any such lease, except as described in each of the Disclosure Package and the

Prospectus and except for such defaults that are not, individually or in the aggregate, reasonably likely to have a Material Adverse Effect. The term “Master Leases” refers to the four second amended and restated master lease agreements, dated as of April 27, 2007, by and among the Operating Partnership and Kindred Healthcare, Inc. and Kindred Healthcare Operating, Inc.

Each of Ventas and each Significant Subsidiary owns, possesses or has the right to employ all patents, patent rights, licenses, inventions, copyrights, know-how, trademarks, service marks, trade names and other intellectual property (collectively, the “Intellectual Property”) necessary to conduct the businesses operated by it as described in each of the Disclosure Package and the Prospectus, except where the failure to own, possess or have the right to employ such Intellectual Property is not reasonably likely to have a Material Adverse Effect. None of Ventas or any Subsidiary has received any notice of infringement of or conflict with (and neither knows of any such infringement or a conflict with) asserted rights of others with respect to any of the foregoing that, if such assertion of infringement or conflict were sustained, is reasonably likely to have a Material Adverse Effect. To the knowledge of each of the Ventas Entities, the use of the Intellectual Property in connection with the business and operations of Ventas and the Subsidiaries does not infringe on the rights of any person, except for such infringement as is not reasonably likely to have a Material Adverse Effect, and neither Ventas nor any Subsidiary has received any notice of, and otherwise has no knowledge of, any threatened or existing action, suit, proceeding or claim by any person challenging use of the Intellectual Property by Ventas and the Subsidiaries.

Except as described in each of the Disclosure Package and the Prospectus, none of Ventas or any Subsidiary has knowledge of any material proposed additional tax assessments against Ventas or any of the Subsidiaries or their assets or property.

(xxvi) Certain ERISA Matters.

With respect to such plans, Ventas and each Subsidiary is in compliance with all applicable provisions of ERISA, except where the failure to be in compliance is not reasonably likely, individually or in the aggregate, to have a Material Adverse Effect.

(xxviii) Insurance for Properties. Each of Ventas and each Subsidiary maintains or causes to be maintained by the lessee under the leases for its properties or by the manager of its properties insurance covering its properties (including title to its properties), assets, operations, personnel and businesses, and such insurance is of such type and in such amounts in accordance with customary industry practice and in Ventas’s reasonable judgment sufficient to protect Ventas and the Subsidiaries and their businesses.

(xxix) Accounting and Other Controls. Ventas maintains effective internal control over financial reporting as defined in the Exchange Act. Each of Ventas and each Subsidiary maintains a system of internal accounting controls sufficient to provide reasonable assurance that: (A) transactions are executed in accordance with management’s general or specific authorizations; (B) transactions are recorded as necessary to permit preparation of its financial statements in conformity with GAAP and to maintain accountability for assets; (C) access to assets is permitted only in accordance with management’s general or specific authorization; and (D) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(xxx) No Material Weakness in Internal Controls. Except as disclosed in each of the Disclosure Package and the Prospectus or in any document incorporated by reference therein, since the end of Ventas’s most recent audited fiscal year, there has been (i) no material weakness in Ventas’s internal control over financial reporting (whether or not remediated) and (ii) no change in Ventas’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, Ventas’s internal control over financial reporting.

(xxxi) No Material Adverse Change in Business. As of September 30, 2011, neither Ventas nor any Subsidiary had incurred any material liabilities or obligations, direct or contingent, that were not set forth in Ventas’s consolidated balance sheet as of September 30, 2011, or in the notes thereto, incorporated by reference in each of the Disclosure Package and the Prospectus, or otherwise described therein, other than the performance by Ventas and each Subsidiary of their respective obligations under ordinary course executory contracts that are not in default, that would not reasonably be expected to have a Material Adverse Effect and that are not required by GAAP, as modified by the Securities Act and the Exchange Act, to be disclosed on a regularly prepared balance sheet or in the notes thereto. Since the respective dates as of which information is given in each of the Registration Statement, the Disclosure Package and the Prospectus, except as otherwise stated therein, (a) none of Ventas or any Subsidiary has (1) incurred any liability or obligation, direct or contingent, that is, individually or in the aggregate, reasonably likely to have a Material Adverse Effect, or (2) entered into any material transaction not in the ordinary course of business, (b) there has not been any event or development in respect of the business or condition (financial or otherwise) of Ventas and the Subsidiaries that, individually or in the aggregate, is reasonably likely to have a Material Adverse Effect and (c) there has not been any change in the long-term debt of Ventas or any of the Subsidiaries or in the authorized capitalization of Ventas.

(xxxii) Section 7 of the Exchange Act and Regulations T, U and X. Neither Ventas nor any Subsidiary (or any agent thereof acting on its behalf other than the Underwriter, as to whom Ventas makes no representation or warranty) has taken, and none of them will take, any action that would cause this Agreement or the sale of the Securities to violate Section 7 of the Exchange Act or Regulations T, U or X of the Board of Governors of the Federal Reserve System, as in effect, or as the same may hereafter be in effect, at the Closing Time.

(xxxiii) Independent Accountants and Financial Statements.

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of (a) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, or any amendment thereto, including any information deemed to be a part thereof pursuant to Rule 430B or 430C under the Securities Act, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading; or (b) any untrue statement or alleged untrue statement of a material fact contained in the Disclosure Package, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact, in each case, 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; provided that (subject to Section 6(c) below) any such settlement is effected with the written consent of Ventas; and

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 therein in reliance upon and in conformity with (A) the Underwriter Information (as defined below) or (B) information relating to the Selling Stockholders furnished to Ventas in writing by any Selling Stockholder expressly for use therein. This indemnity agreement will be in addition to any liability that the Ventas Entities may otherwise have, including, but not limited to, liability under this Agreement.

(b) Indemnification of the Underwriter by the Selling Stockholders. Each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless the Underwriter, its affiliates, directors and officers and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act to the same extent as the indemnity set forth in Section 6(a)(i) herein, to the extent and only to the extent such losses, liabilities, claims, damages or expenses arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with any information relating to such Selling Stockholder furnished to Ventas in writing by the Selling Stockholder expressly for use in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), it being understood that such information consists solely of the name and beneficial ownership information about such Selling Stockholder set forth in the “Selling Stockholders” section of the Prospectus, a copy of which is set forth on Schedule A hereto under the caption “Furnished Information.” In no event shall a Selling Stockholder be required pursuant to this Section 6(b) to indemnify the Underwriter in an amount in excess of the net proceeds received by such Selling Stockholder from the Underwriter for the Securities after deduction of any underwriting discount or commission paid to the Underwriter by or on behalf of the Selling Stockholder.

(c) Indemnification of Ventas Entities, Selling Stockholders, Directors and Officers.

Writing Prospectus, any preliminary prospectus or the Prospectus is the statements contained in the selected paragraphs attached hereto in Annex B that will be included in the “Underwriting” section of the Prospectus (the “Underwriter Information”).

(d) Actions Against Parties; Notification. Each indemnified party shall give 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, except to the extent it is materially prejudiced as a result thereof and in any event shall not relieve it from any liability that it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Sections 6(a) or 6(b) hereof, counsel to the indemnified parties shall be selected by the Underwriter, subject to the reasonable approval of the indemnifying party, and, in the case of parties indemnified pursuant to Section 6(c) hereof, counsel to the indemnified parties shall be selected by Ventas and the Selling Stockholders, as the case may be, subject to the reasonable approval of the indemnifying party. An indemnifying party may participate at its own expense in the defense of any such action, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof; 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; provided further, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of such indemnifying party’s election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel (other than local counsel), reasonably approved by the indemnifying party (or by the Underwriter in the case of Section 6(c)), representing the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action, in each of which cases the fees and expenses of counsel shall be at the expense of the indemnifying 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 reasonably be sought under this Section 6 (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.

(e) 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) hereof 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; provided that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party (1) reimburses such indemnified party in accordance with such request to the extent it considers such request to be reasonable and (2) provides written notice to the indemnified party substantiating the unpaid balance as unreasonable, in each case prior to the date of such settlement.

(f) Other Agreements With Respect to Indemnification. The provisions of this Section 6 shall not affect any agreement among any of the Ventas Entities and the Selling Stockholders with respect to indemnification.

(g) 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 Ventas Entities and the Selling Stockholders on the one hand and the Underwriter 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 Ventas Entities and the Selling Stockholders on the one hand and of the Underwriter on the other hand in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Ventas Entities and the Selling Stockholders on the one hand and the Underwriter 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 (a) in the case of the Ventas Entities and the Selling Stockholders, the net proceeds received by the Selling Stockholders from the offering of the Securities after deduction of any underwriting discount or commission paid to the Underwriter by or on behalf of the Selling Stockholders and (b) in the case of the Underwriter, the total discount or commission received by the Underwriter, in each case as set forth in this Agreement, bear to the net proceeds received by the Selling Stockholders from the offering of the Securities before deduction of any underwriting discount or commission paid to the Underwriter by or on behalf of the Selling Stockholders.

The relative fault of the Ventas Entities and the Selling Stockholders on the one hand and the Underwriter 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 Ventas Entities, the Selling Stockholders or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Ventas Entities, the Selling Stockholders and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 6(g) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 6(g). The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 6(g) 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 6(g), (i) the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to the public were offered to the public exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission and (ii) no Selling Stockholder shall be required to contribute any amount in excess of the amount of the total net proceeds received by such Selling Stockholder from the sale of Securities pursuant to this Agreement after deduction of any underwriting discount or commission paid to the Underwriter by or on behalf of such Selling Stockholder.

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

For purposes of this Section 6(g), each officer and director of the Underwriter, and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as the Underwriter, and each officer and director of any Ventas Entity, and each person, if any, who controls any Ventas Entity within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as such Ventas Entity.

For purposes of this Section 6(g), each person, if any, who controls any Selling Stockholder within the meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as such Selling Stockholder.

The provisions of this Section 6(g) shall not affect any agreement among any of the Ventas Entities and the Selling Stockholders with respect to contribution.

SECTION 7. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement, or in certificates of officers of the Ventas Entities and/or the Selling Stockholders 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 controlling person, or by or on behalf of Ventas and/or the Selling Stockholders, and shall survive delivery of the Securities to the Underwriter.

SECTION 8. Termination of Agreement.

(a) Termination; General. The Underwriter may terminate this Agreement, by notice to Ventas and the Selling Stockholders, at any time at or prior to the Closing Time (i) if there has been, since the Execution Time or since the respective dates as of which information is given in the Registration Statement, any Issuer Free Writing Prospectus, any preliminary prospectus or Prospectus (exclusive of any amendment or supplement thereto), any material adverse change in the business, condition (financial or otherwise), results of operations, performance, properties or business prospects of Ventas and the Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriter, impracticable or inadvisable to market the Securities in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Ventas Entities has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the New York Stock Exchange or in the Nasdaq Stock Market has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA 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 or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 8, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Section 6 shall survive such termination and remain in full force and effect.

SECTION 9. Default by the Selling Stockholders. If a Selling Stockholder shall fail at the Closing Time to sell and deliver the number of Securities which such Selling Stockholder is obligated to sell hereunder, then the Underwriter, by notice to Ventas and the non-defaulting Selling Stockholders, may either (a) terminate this Agreement without any liability on the part of any non-defaulting party except that the provisions of Sections 4 and 6 hereof shall remain in full force and effect or (b) elect to purchase the Securities which the non-defaulting Selling Stockholders have agreed to sell hereunder. No action taken pursuant to this Section 9 shall relieve any Selling Stockholder so defaulting from liability, if any, in respect of such default.

In the event of a default by any Selling Stockholder as referred to in this Section 9, the Underwriter, Ventas and the non-defaulting Selling Stockholders shall have the right to postpone the Closing Time for a period not exceeding seven business days in order to effect any required change in the Prospectus or in any other documents or arrangements.

SECTION 10. No Advisory or Fiduciary Responsibility. Each of the Ventas Entities and each of the Selling Stockholders acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Ventas Entities and the Selling Stockholders on the one hand, and the Underwriter, on the other hand, and the Ventas Entities and the Selling Stockholders are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with each transaction contemplated hereby the Underwriter is and has been acting solely as principal and is not the agent or fiduciary of the Ventas Entities and the Selling Stockholders or their respective affiliates, stockholders, creditors or employees or any other party; (iii) the Underwriter has not assumed and will not assume an advisory or fiduciary responsibility in favor of the Ventas Entities or the Selling Stockholders with respect to any of the transactions contemplated hereby (irrespective of whether the Underwriter has advised or is currently advising the Ventas Entities or the Selling Stockholders on other matters) or any other obligation to the Ventas Entities or the Selling Stockholders with respect to such transactions except the obligations expressly set forth in this Agreement; (iv) the Underwriter and its respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Ventas Entities or the Selling Stockholders; and (v) the Underwriter has not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated hereby and the Ventas Entities or the Selling Stockholders have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) among the Ventas Entities, the Selling Stockholders and the Underwriter with respect to the subject matter hereof. Each of the Ventas Entities and the Selling Stockholders hereby waive and release, to the fullest extent permitted by law, any claims that the Ventas Entities and the Selling Stockholders, as applicable, may have against the Underwriter with respect to any breach or alleged breach of fiduciary duty in connection with the transactions contemplated hereby.

[DRAFT SUBJECT TO S&C OPINION COMMITTEE REVIEW]

, 2012

[Name of Underwriter,

as Representative[s] of the several Underwriters,

c/o [ ],

[ ],

[ ]

New York, New York [ ].

Ladies and Gentlemen:

In connection with the several purchases today by you and the other Underwriters named in Schedule I to the Underwriting Agreement, dated , 2012 (the “Underwriting Agreement”), among Ventas, Inc., a Delaware corporation (the “Company”), the selling stockholders named therein (the “Selling Stockholders”) and you, as Representative[s] of the several Underwriters named therein (the “Underwriters”), of [ ] shares of the Company’s Common Stock, par value $0.25 per share (“Common Stock”), including [ ] shares of Common Stock to be purchased from Prometheus Senior Quarters LLC, a Delaware limited liability company (“Prometheus”), [ ] shares of Common Stock to be purchased from Lazard Senior Housing Partners LP, a Delaware limited partnership (“LSHP”), and [ ] shares of Common Stock to be purchase from LSHP Coinvestment Partnership I LP, a Delaware limited partnership (“LSHP Coinvest”), we, as special counsel for the Selling Stockholders, have examined such limited liability company, limited partnership and corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that:

1. The Underwriting Agreement has been duly authorized, executed and delivered by each of the Selling Stockholders.

2. The sale of the shares of Common Stock by Prometheus to the Underwriters pursuant to the Underwriting Agreement does not violate (a) the Certificate of Formation of Prometheus or (b) any Federal law of the United States, law of the State of New York or provision of the Delaware Limited Liability Act applicable to Prometheus; provided, however, that for purposes of this paragraph (2), we express no opinion with respect to Federal or state securities laws, other antifraud laws, fraudulent transfer laws and the Employee Retirement Income Security Act of 1974 and related laws; provided, further, that insofar as performance by Prometheus of its obligations under the Underwriting Agreement is concerned, we express no opinion as to bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability relating to or affecting creditors’ rights.

3. The sale of the shares of Common Stock by LSHP to the Underwriters pursuant to the Underwriting Agreement does not violate (a) the Certificate of Limited Partnership of LSHP or (b) any Federal law of the United States, law of the State of New York or provision of the Delaware Revised Uniform Limited Partnership Act applicable to LSHP; provided, however, that for purposes of this paragraph (3), we express no opinion with respect to Federal or state securities laws, other antifraud laws, fraudulent transfer laws and the Employee Retirement Income Security Act of 1974 and related laws; provided, further, that insofar as performance by LSHP of its obligations under the Underwriting Agreement is concerned, we express no opinion as to bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability relating to or affecting creditors’ rights.

4. The sale of the shares of Common Stock by LSHP Coinvest to the Underwriters pursuant to the Underwriting Agreement does not violate (a) the Certificate of Limited Partnership of LSHP Coinvest or (b) any Federal law of the United States, law of the State of New York or provision of the Delaware Revised Uniform Limited Partnership Act applicable to LSHP Coinvest; provided, however, that for purposes of this paragraph (4), we express no opinion with respect to Federal or state securities laws, other antifraud laws, fraudulent transfer laws and the Employee Retirement Income Security Act of 1974 and related laws; provided, further, that insofar as performance by LSHP Coinvest of its obligations under the Underwriting Agreement is concerned, we express no opinion as to bankruptcy, insolvency, reorganization, moratorium or similar laws of general applicability relating to or affecting creditors’ rights.

5. Upon payment of the purchase price by the Underwriters for the shares of Common Stock being sold by the Selling Stockholders (the “Shares”) and the delivery to the Depository Trust Company (“DTC”) or its agent of such Shares registered in the name of Cede & Co. or such other nominee designated by DTC, and the crediting of such Shares to the several Underwriters’ accounts with DTC, all as provided in the Underwriting Agreement, the Underwriters will acquire a valid “security entitlement” (within the meaning of Section 8-501 of the Uniform Commercial Code as adopted in the State of New York (the “Code”)) to such Shares, and no action based on an “adverse claim” (as defined in Section 8-102 of the Code) may be asserted against the Underwriters with respect to such security entitlement (assuming that the Underwriters are without notice of any such adverse claim).

For purposes of paragraph (5) above, as to factual matters we have relied entirely upon the representations and warranties of the Selling Stockholders in the Underwriting Agreement and have assumed, without further inquiry, the accuracy of those representations. In addition, for purposes of paragraph (5), we have assumed that (i) DTC is a “clearing corporation” as defined in Section 8-102 of the Code, (ii) the State of New York is the “securities intermediary’s jurisdiction” of DTC for purposes of Section 8-110 of the Code, and (iii) the Underwriters have the interest in the Shares purchased by the Underwriters credited to one or more “securities accounts” (as defined in Section 8-501 of the Code) of the respective Underwriters maintained with the DTC.

The foregoing opinion is limited to the Federal laws of the United States, the laws of the State of New York, the Delaware Limited Liability Act and the Delaware Revised Uniform Limited Partnership Act, and we are expressing no opinion as to the effect of the laws of any other jurisdiction. The opinion in paragraph (5) hereof is limited to Article 8 of the Code and does not address (i) laws of jurisdictions other than New York or laws of New York except for Article 8, (ii) what law governs interests in such security entitlements, or (iii) the effect, if any, of laws of jurisdictions other than New York on interests in such security entitlements.

In rendering the foregoing opinion, we have relied as to certain matters upon information obtained from public officials, the general partners and managing members of the Selling Stockholders, and partners, officers, employees and other representatives of the Selling Stockholders, Lazard Alternative Investments LLC, Lazard Frères Real Estate Investors L.L.C., and their respective affiliates, and other sources believed by us to be responsible, and we have assumed that each of the Selling Stockholders has been duly organized, that the certificates for the Shares conform to the specimen thereof examined by us and have been duly countersigned and registered by the transfer agent and registrar of the Common Stock, and that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

This letter is furnished by us as special counsel for the Selling Stockholders to the Underwriters and is solely for the benefit of the Underwriters.

Very truly yours,

Exhibit B-1

FORM OF LOCK-UP LETTER

[ ], 2012

[ ]

Dear Ladies and Gentlemen:

The undersigned understands that [ ] (the “Underwriter”) entered into an Underwriting Agreement (“Underwriting Agreement”) with Ventas, Inc., (the “Company”), the other Ventas Entities (as defined in the Underwriting Agreement) and the Selling Stockholders (as defined in the Underwriting Agreement) providing for the offering (the “Offering”) by the Underwriter, of [ ] shares of the Company’s common stock, par value $0.25 per share (the “Securities”). Terms used herein and not otherwise defined shall have the meaning assigned to such terms in the Underwriting Agreement.

To induce the Underwriter to continue its efforts in connection with the Offering, the undersigned hereby agrees that, without the prior written consent of the Underwriter, it will not, during the period commencing on the date hereof and ending 60 days after the date of the Prospectus, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to (a) transfers of Common Stock by gift, will or intestacy, including without limitation transfers by gift, will or intestacy to family members of the undersigned or to a settlement or trust established under the laws of any country, (b) transfers or sales of Common Stock pursuant to any contract, instruction or plan, including a contract, instruction or plan complying with Rule 10b5-1 of the Regulations of the Securities Exchange Act of 1934, as amended, that has been entered into by the undersigned prior to the date of this Letter Agreement, or any amendment or replacement of any such contract, instruction or plan with the same or a different firm on or after the date hereof, so long as the aggregate number of shares of Common Stock subject to such amended or replacement contract, instruction or plan does not exceed the maximum amount of Common Stock under the original contract, instrument or plan, and the exercise of options in connection therewith or (c) the withholding of shares of Common Stock to pay taxes upon the vesting of restricted stock outstanding on the date hereof, provided that in the event of exception (a) above, (i) the transferee or donee executes and delivers to the Underwriter a lock-up agreement in form and substance reasonably satisfactory to the Underwriter, (ii) no filing by any party (transferor, transferee, donor or donee) under the Securities Exchange Act of 1934 shall be required or shall be voluntarily made in connection with such transfer or distribution (other than a filing on a

Form 4, Form 5, Schedule 13D or Schedule 13G (or 13D/A or 13G/A)), (iii) each party (transferor, transferee, donor or donee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934) to make, and shall agree to not voluntarily make, any public announcement of the transfer or disposition (other than a filing on a Form 4, Form 5, Schedule 13D or Schedule 13G (or 13D/A or 13G/A)) and (iv) the undersigned or the undersigned’s legal representative notifies the Underwriter at least three business days prior to the proposed transfer or disposition. In addition, the undersigned agrees that, without the prior written consent of the Underwriter, it will not, during the period commencing on the date hereof and ending 60 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

The undersigned understands that the Company, the Selling Stockholders and the Underwriter are relying upon this Letter Agreement in proceeding toward consummation of the Offering. The undersigned further understands that this Letter Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Company, the Selling Stockholders and the Underwriter.

This Lock-Up Agreement shall lapse and become null and void on the date (the “Agreement Expiration Date”) that is the first to occur of: (i) the date on which the Selling Stockholders notify the Underwriter in writing that they do not intend to proceed with the Offering, (ii) the date on which the Underwriting Agreement shall terminate or be terminated (excluding any provisions thereof related to expense reimbursement, contribution or indemnity that shall survive such termination), and (iii) the first day after the last day of the 60-day restricted period as extended in accordance herewith.

VERBAL INFORMATION

INCLUDED IN THE

DISCLOSURE PACKAGE PROVIDED

ORALLY BY THE UNDERWRITER

1.	Number of shares: 21,070,658

Price: Variable.

Annex B

SELECTED PARAGRAPHS OF THE “UNDERWRITING” SECTION OF THE

PROSPECTUS

If the underwriter creates a short position in the common stock in connection with the offering, i.e., if the underwriter sells more shares than are listed on the cover of this prospectus supplement, the underwriter may reduce that short position by purchasing shares in the open market. Purchases of the common stock to stabilize its price or to reduce a short position may cause the price of the common stock to be higher than it might be in the absence of those purchases.

2.	In connection with the offering, the underwriter or securities dealers may distribute this prospectus supplement and the accompanying prospectus by electronic means, such as e-mail.

3.	An affiliate of the underwriter is a lender under our unsecured revolving credit facility and our unsecured term loan facilities.

The underwriter is offering the shares, subject to prior sale, when, as and if offered to and accepted by the underwriter, subject to approval of legal matters by counsel and other conditions. The underwriter reserves the right to withdraw, cancel or modify this offer and to reject orders in whole or in part.

The underwriter proposes to offer the shares of common stock offered hereby from time to time for sale in one or more transactions on the New York Stock Exchange, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt and acceptance by the underwriter and subject to the underwriter’s right to reject any order in whole or in part. The underwriter may effect such transactions by selling the shares of common stock to or through dealers and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal. The difference between the price at which the underwriter purchases shares and the price at which the underwriter resells such shares, which may include a commission equivalent of up to $.05 per share, may be deemed underwriting compensation.

Very truly yours,
