Dear Stockholder:

We cordially invite you to attend a special meeting of stockholders of Cogdell Spencer Inc., a Maryland corporation, which we refer to as the Company, to be held on March 9, 2012 at 9:00 a.m., local time, at the Hampton Inn and Suites, SouthPark at Phillips Place, 6700 Phillips Place Court, Charlotte, North Carolina 28210.

On December 24, 2011, the Company entered into a merger agreement providing for the acquisition of the Company by Ventas, Inc. The acquisition will be accomplished by (i) the merger of the Company with TH Merger Corp, Inc., a wholly-owned subsidiary of Ventas, pursuant to which the Company will become a wholly-owned subsidiary of Ventas, which we refer to as the Company Merger, and (ii) the merger of the Company's operating partnership, Cogdell Spencer LP, with TH Merger Sub, LLC, a wholly-owned subsidiary of Ventas, Inc., which we refer to as the Partnership Merger, and together with the Company Merger, the Mergers. At the special meeting, you will be asked to consider and vote upon a proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

If the Company Merger contemplated by the merger agreement is completed, you will be entitled to receive $4.25 in cash, without interest, less any applicable withholding taxes, for each share of our common stock you owned at the effective time of the Company Merger, which represents a premium of approximately 11.3% to the average closing price of our common stock during the 30-day trading period ended on December 23, 2011 (the last trading day prior to the public announcement of the execution of the merger agreement) and a premium of approximately 8.4% to the closing price of our common stock on December 23, 2011. If the Company Merger is not approved by the stockholders of the Company, the Partnership Merger will also not be completed.

In addition to voting upon a proposal to approve the Company Merger at the special meeting, you will be asked to vote on a proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger.

The board of directors of the Company has determined that the Company Merger is advisable to, and in the best interests of, the Company and its stockholders and has approved the merger agreement and the Company Merger. The board of directors of the Company made its determination after consideration of a number of factors, which are more fully described in the accompanying proxy statement.The board of directors of the Company recommends that you vote "FOR" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, "FOR" the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger, and "FOR" the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Approval of the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement requires the affirmative vote of holders of a majority of the outstanding shares of our common stock entitled to vote thereon. Approval of the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which the presence, in person or by proxy, of stockholders entitled to cast a majority of all the votes entitled to be cast at such meeting exists. Approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which the presence, in person or by proxy, of stockholders entitled to cast a majority of all the votes entitled to be cast at such meeting exists.

Reasons for the Company Merger; Recommendation of the Board of Directors (Page 37)

After careful consideration of various factors described in the section entitled "The Merger—Reasons for the Company Merger; Recommendation of the Board of Directors," the board of directors of the Company, other than Mr. David Lubar, who was excluded from, and did not participate in, deliberations of the Company's board of directors regarding the merger agreement and related transactions, determined that the Company Merger is advisable to, and in the best interests of, the Company and its stockholders and approved the merger agreement and the Company Merger. References to the board of directors in this proxy statement shall mean the board of directors of the Company, other than Mr. David Lubar, unless otherwise expressly stated. Mr. David Lubar resigned from the Company's board of directors on January 5, 2012.

In considering the recommendation of the board of directors with respect to the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, you should be aware that some of our directors and executive officers have interests in the Company Merger that are different from, or in addition to, yours. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the Company Merger, and in recommending that the Company Merger be approved by the stockholders of the Company. See the section entitled "The Company Merger—Interests of the Company's Directors and Executive Officers in the Company Merger" beginning on page 50.

The board of directors recommends that you vote "FOR" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, "FOR" the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger and "FOR" the proposal to adjourn the special meeting, if necessary or appropriate.

Opinion of the Company's Financial Advisor (Page 40)

In connection with the Mergers, the Company's board of directors received a written opinion, dated December 23, 2011, from Citigroup Global Markets Inc., which we refer to as Citi, as to the fairness, from a financial point of view and as of the date of the opinion, of the $4.25 per share merger consideration to be received in the Company Merger by holders of Company common stock. The full text of Citi's written opinion, which is attached to this proxy statement asAnnex B, sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken.Citi's opinion was provided for the information of the Company's board of directors (in its capacity as such) in connection with its evaluation of the Company Merger and only addressed the fairness, from a financial point of view, of the $4.25 per share merger consideration to be received by holders of Company common stock in the Company Merger. Citi's opinion did not address any other aspects or implications of the Mergers or any related transaction. Citi was not requested to consider, and its opinion did not address, the underlying business decision of the Company to effect the Mergers or any related transaction, the relative merits of the Mergers or any related transaction as compared to any alternative business strategies that might exist for the Company or OP or the effect of any other transaction in which the Company or OP might engage. Citi's opinion is not intended to be and does not constitute a recommendation to any security holder as to how such security holder should vote or act on any matters relating to the proposed Mergers, any related transaction or otherwise.

Interests of the Company's Directors and Executive Officers in the Company Merger (Page 50)

When considering the recommendation of the board of directors that you vote for the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, you should be aware that some of our directors and executive officers have interests in the Company Merger that are different from, or in addition to, your interests as a stockholder. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the Company Merger, and in recommending that the Company Merger be approved by the stockholders of the Company. These interests include the following:

•: the vesting of all unvested long-term incentive plan units of limited partnership interest in the Operating Partnership, which we refer to as LTIP Units, and shares of restricted stock held by our executive officers and directors, and the cashing out of such awards;
•: pursuant to employment agreements with certain of our executive officers, the payment of severance payments in connection with a termination of employment that may occur following the Company Merger;
•: our current and former directors and officers will continue to be indemnified after the completion of the Company Merger and will have the benefit of liability insurance for six years after completion of the Company Merger; and
•: Mr. David Lubar, one of the Company's former directors, who resigned from the Company's board of directors on January 5, 2012, is a principal of an investment fund that is providing equity funding to the buyer of the Erdman business in an amount necessary to consummate the Erdman Sale (as described below in this section under "Sale of the Erdman Business"). The closing of the Erdman Sale is a condition to the closing of the Company Merger.

The receipt of the cash consideration in connection with the Company Merger will generally be treated as a taxable transaction for U.S. federal income tax purposes in which shareholders will recognize gain or loss in an amount equal to the difference between the total cash consideration received and each respective shareholder's adjusted basis in their shares of Company common stock, subject to certain exceptions described in the section entitled "Material U.S. Federal Income Tax Consequences of the Company Merger" beginning on page 56. In considering the recommendation of the board of directors that you vote for the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, you should consider the matters discussed in the section entitled "Material U.S. Federal Income Tax Consequences of the Company Merger".

The Merger Agreement (Page 60)

Treatment of Company Common Stock, Series A Preferred Stock, Operating Partnership Units, Restricted Stock and LTIP Units (Pages 61)

•: Common Stock. At the effective time of the Company Merger, each share of Company common stock issued and outstanding immediately prior to the effective time of the Company Merger (except for the excluded shares) will automatically convert into the right to receive the per share merger consideration of $4.25 in cash, without interest, less any applicable withholding taxes.
•: Series A Preferred Stock. At the effective time of the Company Merger, each share of Series A preferred stock of the Company, par value $0.01 per share, which we refer to as the Series A Preferred Stock, issued and outstanding immediately prior to the effective time of the Company Merger (other than shares of Series A Preferred Stock owned, directly or indirectly, by the Company, any of the Company's subsidiaries, Ventas, MergerSub or any other subsidiary of

Table of Contents

Ventas, which shall automatically be cancelled and retired and shall cease to exist and for which no consideration shall be delivered, and which we refer to collectively as the excluded preferred shares) will automatically convert into the right to receive $25.00 in cash, without interest, which amount we refer to as the preferred per share merger consideration, and subject to deduction for any required withholding tax, plus all accrued and unpaid dividends thereon through and including the closing date of the Company Merger.

•: Operating Partnership Units. At the effective time of the Partnership Merger, each unit representing a limited partnership interest in the Operating Partnership, which we refer to as an OP Unit, issued and outstanding immediately prior to the effective time of the Partnership Merger (other than OP Units owned directly or indirectly by the Company or any of the Company's subsidiaries, which we refer to as excluded OP Units, or any LTIP Units) will automatically convert into the right to receive the per share merger consideration, without interest and subject to deduction for any required withholding tax, and all such units will cease to exist. The general partnership interest of the Operating Partnership will remain outstanding and will be the only general partnership interest in the Operating Partnership after the effective time of the Partnership Merger. Each Series A Preferred Partnership Unit will be automatically cancelled without payment of any consideration.
•: Restricted Stock. At the effective time of the Company Merger, each share of Company common stock subject to restrictions on transfer and/or forfeiture granted under the Company's equity plans or otherwise that is outstanding immediately prior to the effective time will become fully vested and all such shares will automatically convert into the right to receive the per share merger consideration, without interest, less any applicable withholding taxes.
•: LTIP Units. Immediately before the effective time of the Partnership Merger, each unvested LTIP Unit granted under the Operating Partnership's long-term incentive plans or otherwise that is outstanding at such time will become fully vested and each vested LTIP Unit will automatically convert into an OP Unit, or fraction thereof. Accordingly, holders of LTIP Units will generally receive the per share merger consideration, without interest, less any applicable withholding taxes.

Restrictions on Solicitation of Other Acquisition Proposals (Page 70)

We have agreed that we, the Operating Partnership and our other subsidiaries will not, and will use reasonable best efforts to cause our and their respective officers, directors, employees, consultants, agents, advisors and other representatives not to, directly or indirectly:

•: initiate, solicit, knowingly facilitate or encourage (including by way of providing non-public information) the submission of any acquisition proposal or any inquiries, proposals or offers that reasonably may be expected to lead to, any acquisition proposal;
•: engage in any discussions or negotiations or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations;
•: approve, adopt or recommend, or propose to approve, adopt or recommend, an acquisition proposal or enter into any other similar agreement providing for or relating to an acquisition proposal;
•: enter into any agreement or agreement in principle requiring the Company or the Operating Partnership to abandon, terminate or fail to consummate the Mergers or breach its obligations under the merger agreement; or
•: terminate, waive, amend, release or fail to enforce any standstill agreement.

Table of Contents

We, the Operating Partnership and our other subsidiaries have also agreed to immediately cease and cause to be terminated any and all activities, solicitations, encouragement, discussions or negotiations with any person other than Ventas and MergerSub or any representatives of such persons conducted previously with respect to any acquisition proposal and to request the prompt return or destruction of all confidential information previously furnished to other parties.

However, at any time prior to the time our stockholders approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, if we receive a bona fide written acquisition proposal from any person that did not result from a breach of our obligations under the preceding paragraph, and that our board of directors determines in good faith (after consultation with our outside counsel and financial advisor) constitutes or is reasonably likely to lead to a superior proposal, we may (i) furnish information with respect to the Company, the Operating Partnership and the other subsidiaries of the Company to the person making the acquisition proposal (pursuant to an acceptable confidentiality agreement); provided that any non-public information concerning the Company, the Operating Partnership or any other subsidiary of the Company provided to such person is promptly provided to Ventas to the extent not previously provided; and (ii) participate in discussions or negotiations with such person regarding the acquisition proposal; provided, that we shall notify Ventas in writing within 24 hours of any such determination by our board of directors that such acquisition proposal constitutes or is reasonably likely to constitute a superior proposal and that failure to take such action would be reasonably likely to lead to a breach of the duties of our directors to our stockholders under applicable law.

Furthermore, at any time before the Company Merger is approved by our stockholders, if our board of directors determines in good faith (after consultation with our outside legal counsel and financial advisor) that an acquisition proposal is a superior proposal, we may terminate the merger agreement and enter into any acquisition, merger or similar agreement, which we refer to as an alternative acquisition agreement, with respect to such superior proposal, so long as we comply with certain terms of the merger agreement, including paying a termination fee and expense reimbursement to Ventas. See "The Merger Agreement—Termination Fees" beginning on page 79.

Conditions to the Mergers (Page 76)

The respective obligations of the Company, the Operating Partnership, Ventas, MergerSub and OP MergerSub to consummate the Mergers are subject to the satisfaction or waiver of certain customary conditions, including the approval of the Company Merger by our stockholders, the absence of any restraining orders, injunctions or other legal restraints prohibiting the Mergers, the accuracy of the representations and warranties of the parties, compliance by the parties with their respective obligations under the merger agreement, our continuing qualification as a REIT and the closing of the Erdman Sale (described below in this section under "Sale of the Erdman Business"). The obligation of Ventas, MergerSub and OP MergerSub to consummate the Mergers is also subject to the absence of any event, change or occurrence that has had, individually or in the aggregate, a material adverse effect on us, as described under "The Merger Agreement—Representations and Warranties" beginning on page 64.

Termination (Page 77)

We and Ventas may, by mutual written consent, terminate the merger agreement and abandon the Mergers at any time prior to the effective time of the Company Merger, whether before or after the approval of the Company Merger by our stockholders.

The merger agreement may also be terminated and the Mergers abandoned at any time prior to the effective time of the Company Merger by either Ventas or the Company, if:

•: the closing of the Mergers has not occurred on or before June 29, 2012, which we refer to as the termination date; provided that this termination right will not be available to a party if the

Table of Contents

failure of such party to perform or comply in all material respects with the covenants and agreements of such party set forth in the merger agreement shall have been the cause of, or that resulted in, the failure of the merger to have been consummated by the termination;

•: if any governmental entity shall have issued an order, decree or ruling or taken any other action permanently enjoining, restraining or otherwise prohibiting either of the Mergers or any of the other transactions contemplated by the merger agreement and such order, decree, ruling or other action shall have become final and non-appealable (provided that the termination right described in this bullet will only be available to a party that has used its reasonable best efforts to prevent the entry of and/or to procure the removal, reversal, dissolution, setting aside or invalidation of any such order, decree, ruling or other action); or
•: our stockholders meeting has been held and completed and our stockholders have not approved the Company Merger pursuant to the terms and conditions set forth in the merger agreement at such meeting (provided that the termination right described in this bullet will not be available to us if the failure to obtain the stockholder approval is caused by any action or failure to act of the Company that constitutes a material breach of the merger agreement).

The merger agreement may also be terminated by the Company, if:

•: at any time prior to the approval of the Company Merger by our stockholders, (i) we enter into an alternative acquisition agreement with respect to a superior proposal and (ii) we pay Ventas the termination fee and expense reimbursement discussed under "The Merger Agreement—Termination Fees" beginning on page 79 (provided that this right will not be available to us unless we have complied with the notice and other requirements of the merger agreement described under "The Merger Agreement—Restrictions on Solicitation of Other Acquisition Proposals" beginning on page 70);
•: Ventas, MergerSub or OP MergerSub shall have breached any of their respective representations or warranties in the merger agreement or they shall have failed to perform or comply with any covenant or agreement contained in the merger agreement and Ventas shall have failed within 15 days after notice thereof from the Company to cure such breach or failure, in either case such that the conditions to the obligations of the Company and the Operating Partnership under the merger agreement, as the case may be, would be incapable of being satisfied by the termination date; or
•: the conditions to the obligations of Ventas to consummate the Mergers have been satisfied (other than those conditions that by their nature are to be satisfied by actions taken at the closing of the merger), and Ventas fails to consummate the transactions contemplated by the merger agreement within six business days following the date on which the closing of the Mergers should have occurred under the merger agreement and we stood ready, willing and able to consummate the Mergers on that date (subject to Ventas's right under the merger agreement to extend the date on which the closing of the Mergers should have occurred).

The merger agreement may also be terminated by Ventas, if:

•: we or our board of directors shall have approved, endorsed or recommended that the Company enter into, or the Company shall have entered into, a definitive agreement or any letter of intent, memorandum of understanding or similar agreement providing for a transaction that is an acquisition proposal;
•: our board of directors shall have withdrawn or modified in a manner adverse to Ventas the approval, recommendation or declaration of advisability of the Company Merger, the merger agreement or the transactions contemplated by the merger agreement, which we refer to as an adverse recommendation change;

Table of Contents

•: we materially breach our obligations under the merger agreement with respect to the solicitation of acquisition proposals;
•: we breach any of our obligations under the merger agreement with respect to the preparation of this proxy statement or the calling of the special meeting;
•: we or our board of directors approves of or recommends that the stockholders tender their shares of Company common stock in any tender or exchange offer or if we fail to send to the stockholders, within ten business days after the commencement of such tender or exchange offer, a statement that the Company recommends rejection of such tender or exchange offer;
•: the Company or the Operating Partnership shall have breached any of their respective representations or warranties in the merger agreement or they shall have failed to perform or comply with any covenant or agreement contained in the merger agreement and the Company shall have failed within 15 days after notice thereof to the Company from Ventas to cure such breach or failure, in either case such that the conditions to the obligations of Ventas, MergerSub and OP MergerSub under the merger agreement, as the case may be, would be incapable of being satisfied by the termination date;
•: the Erdman purchase agreement shall have been terminated (other than as a result of the receipt of a superior proposal for the purchase of the Erdman Companies), or the Erdman Sale (as such terms are defined below) shall have failed to close within two business days of the satisfaction or waiver of the conditions contained in the merger agreement; or
•: Ventas is ready, willing and able to consummate the Mergers, and the closing does not occur within two business days after the first date all of the conditions to the Company's obligations to consummate the Mergers are satisfied or waived, and during that two business day period, the net debt closing condition (as described under "The Merger Agreement—Conditions to the Mergers" on page 76) is not satisfied.

Termination Fees (Page 79)

If the merger agreement is terminated in certain circumstances described under "The Merger Agreement—Termination Fees" beginning on page 79:

•: the Company may be obligated to pay Ventas a termination fee of $15.0 million and/or an expense reimbursement equal to $5.0 million; or
•: Ventas may be obligated to pay the Company a termination fee of $15.0 million and an expense reimbursement equal to $5.0 million.

Remedies (Page 81)

In addition to the termination fees and/or expense reimbursements described under "The Merger Agreement—Termination Fees" beginning on page 79, the parties are entitled to injunctive relief to prevent breaches of the merger agreement and to specific performance of the terms of the merger agreement, including the right of the parties to cause the transactions contemplated by the merger agreement to be consummated on the terms set forth in the merger agreement, in addition to any other remedy at law or equity or pursuant to the merger agreement to which the parties may be entitled. Except as otherwise provided in the merger agreement, all remedies available under the agreement, at law or otherwise, shall be deemed cumulative and not alternative or exclusive of other remedies. The exercise by any party of a particular remedy shall not preclude the exercise of any other remedy.

Sale of the Erdman Business (Page 83)

Simultaneously with the execution of the merger agreement, the Company's subsidiary, Cogdell Spencer TRS Holdings, LLC, which we refer to as TRS Holdings, entered into a stock purchase agreement with Madison DB Acquisition, LLC, which we refer to as Madison DB, pursuant to which Madison DB will acquire all of the shares of MEA Holdings, Inc., which we refer to as MEA and which, together with its subsidiaries, engage in design-build and related advisory services under the Marshall Erdman name, which we refer to collectively as the Erdman business. We refer to MEA and its subsidiaries collectively as the Erdman Companies, and we refer to the stock purchase agreement, dated as of December 24, 2011, among Madison DB, TRS Holdings, and the Company as guarantor, as the Erdman purchase agreement. We refer to the transactions contemplated by the Erdman purchase agreement as the Erdman Sale. TRS Holdings will, prior to closing, contribute $11,720,000 (subject to certain adjustments) to MEA, and will extinguish certain intercompany indebtedness of MEA. At closing, Madison DB will pay $1.00 to TRS Holdings and will contribute a net amount of $10,620,000 in working capital to MEA. Consummation of the Erdman Sale is subject to customary closing conditions, including satisfaction of all conditions to closing of the transactions contemplated by the merger agreement.

Mr. David Lubar, one of the Company's former directors, who resigned from the Company's board of directors on January 5, 2012, is a principal of the investment fund that is providing Madison DB with its required equity funding to consummate the Erdman Sale. Mr. Lubar was excluded from, and did not participate in, deliberations of the Company's board of directors regarding the merger agreement or the Erdman purchase agreement.

Go-Shop Period (Page 84)

Except as described below, the Company stockholders will not receive any consideration from the sale of MEA pursuant to the Erdman purchase agreement distinct from the consideration received pursuant to the merger agreement. Under the Erdman purchase agreement, during the period beginning on December 24, 2011 and continuing until 12:01 a.m. (EST) on February 10, 2012, which we refer to as the go-shop period, TRS Holdings, MEA or its subsidiaries may initiate, solicit and encourage any alternative acquisition proposals from third parties, provide non-public information and participate in discussions and negotiate with third parties with respect to alternative proposals to acquire the Erdman Companies, and terminate the Erdman purchase agreement in order to enter into a substitute Erdman purchase agreement to sell the Erdman Companies to a third party which is expected to contain the same general terms and conditions as the Erdman purchase agreement. In the event TRS Holdings enters into a substitute purchase agreement, it must pay to Madison DB a termination fee of $400,000 and, pursuant to the terms of the merger agreement, the Company and the Operating Partnership would, prior to consummation of the Mergers, distribute to the holders of the Company common stock and the OP Units and LTIP Units, respectively, an amount in cash equal to the net proceeds (after deduction of the $400,000 termination fee and any incremental expenses associated with the go-shop process) from the sale of the Erdman Companies pursuant to the substitute purchase agreement.

The Company, with the assistance of its financial advisor, began actively soliciting indications of interest from third parties regarding the possible acquisition of the Erdman business in early January 2012.

Market Price of Company Common Stock (Page 86)

The closing price of Company common stock on the New York Stock Exchange, or NYSE, on December 23, 2011, the last trading day prior to the public announcement of the merger agreement, was $3.92 per share of Company common stock. On February 3, 2012, the most recent practicable date

Table of Contents

before this proxy statement was mailed to our stockholders, the closing price for Company common stock on the NYSE was $4.25 per share of Company common stock. You are encouraged to obtain current market quotations for Company common stock in connection with voting your shares of Company common stock.

No Appraisal Rights (Page 89)

Holders of Company common stock are not entitled to exercise demand or appraisal rights in connection with the Company Merger.

Delisting and Deregistration of Company Common Stock (Page 89)

If the Company Merger is completed, the Company common stock will be delisted from the NYSE and deregistered under the Securities Exchange Act of 1934, as amended, or the Exchange Act. As such, we would no longer file periodic reports with the Securities and Exchange Commission, which we refer to as the SEC, on account of the Company common stock.

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE COMPANY MERGER

The following questions and answers are intended to address briefly some commonly asked questions regarding the special meeting and the Company Merger. These questions and answers may not address all questions that may be important to you as a Company stockholder. Please refer to the "Summary" and the more detailed information contained elsewhere in this proxy statement, the annexes to this proxy statement and the documents referred to in this proxy statement, which you should read carefully and in their entirety. You may obtain the information incorporated by reference in this proxy statement without charge by following the instructions under "Where You Can Find More Information" beginning on page 89.

Q.: What is the proposed transaction and what effects will it have on the Company?
A.: The proposed transaction is the acquisition of the Company and the Operating Partnership by Ventas pursuant to the merger agreement.

If the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement is approved by our stockholders and the other closing conditions under the merger agreement have been satisfied or waived, either (i) MergerSub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of Ventas, or (ii) the Company will merge with and into MergerSub, with MergerSub surviving as a wholly-owned subsidiary of Ventas. Regardless of the manner in which the Company Merger is structured, you will not be entitled to own any shares of the capital stock of the Surviving Company after the Company Merger is completed.

Additionally, pursuant to the merger agreement, OP MergerSub will merge with and into the Operating Partnership, with the Operating Partnership surviving as a wholly-owned subsidiary of Ventas. However, if the Company Merger is not approved by the stockholders of the Company, the Partnership Merger will not be completed.

As a result of the Company Merger, the Company will no longer be a publicly held corporation, and you will no longer have any interest in our future earnings or growth. In addition, the Company common stock will be delisted from the NYSE and deregistered under the Exchange Act, and we will no longer file periodic reports with the SEC on account of the Company common stock.

Q.: What will I receive if the Company Merger is completed?
A.: Upon completion of the Company Merger, you will be entitled to receive the per share merger consideration of $4.25 in cash, without interest, less any applicable withholding taxes, for each share of Company common stock that you own as of the effective time of the Company Merger.
Q.: How does the per share merger consideration compare to the market price of Company common stock prior to announcement of the Company Merger?
A.: The per share merger consideration represents a premium of approximately 11.3% to the average closing share price of Company common stock during the 30-day trading period ended on December 23, 2011, the last trading day prior to the public announcement of the merger agreement, and a premium of approximately 8.4% to the closing share price of Company common stock on December 23, 2011.
Q.: How does the board of directors recommend that I vote?
A.: The board of directors recommends that you vote "FOR" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, "FOR" the proposal to approve, on a non-binding advisory basis, the compensation that certain executive

Table of Contents

officers of the Company will or may receive in connection with the Company Merger, and "FOR" the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Q.: When do you expect the Company Merger and related transactions to be completed?
A.: We are working towards completing the Company Merger and related transactions as soon as possible. Assuming timely satisfaction of necessary closing conditions, including the approval by our stockholders of the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, we anticipate that the Company Merger and related transactions will be completed during the second quarter of 2012.
Q.: What happens if the Company Merger is not completed?
A.: If the Company Merger pursuant to the terms and conditions set forth in merger agreement is not approved by the stockholders of the Company or if the Company Merger is not completed for any other reason, the stockholders of the Company will not receive any payment for their shares of Company common stock in connection with the Company Merger. Instead, the Company will remain an independent public company, and the Company's common stock will continue to be listed and traded on the NYSE. Additionally, if the Company Merger is not approved by the stockholders of the Company or if the Company Merger is not completed for any other reason, the Partnership Merger and the Erdman Sale will also not be completed.

Furthermore, under specified circumstances, the Company may be required to pay to Ventas, or may be entitled to receive from Ventas, a termination fee and/or expense reimbursement with respect to the termination of the merger agreement, as described under "The Merger Agreement—Termination Fees" beginning on page 79.

Q.: Is the Company Merger expected to be taxable to me?
A.: Yes. The receipt of the cash consideration in connection with the Company Merger will generally be treated as a taxable transaction for U.S. federal income tax purposes in which shareholders will recognize gain or loss in an amount equal to the difference between the total cash consideration received and each respective shareholder's adjusted basis in their shares of Company stock, subject to certain exceptions described in the section entitled "Material U.S. Federal Income Tax Consequences of the Company Merger" beginning on page 56. You should read "The Company Merger—Material U.S. Federal Income Tax Consequences of the Company Merger" beginning on page 56 for a more detailed discussion of the U.S. federal income tax consequences of the Company Merger to U.S. and non-U.S. holders. You should also consult your tax advisor for a complete analysis of the effect of the Company Merger on your federal, state and local and/or foreign taxes.
Q.: Why am I receiving this proxy statement and proxy card or voting instruction form?
A.: You are receiving this proxy statement and proxy card or voting instruction form because you owned shares of Company common stock as of the record date, which entitles you to receive notice of, and to vote at, the special meeting. This proxy statement describes matters on which we urge you to vote and is intended to assist you in deciding how to vote your shares of Company common stock with respect to such matters.

Table of Contents

Q.

When and where is the special meeting?

A.

The special meeting of stockholders of the Company will be held on March 9, 2012 at 9:00 a.m., local time, at the Hampton Inn and Suites, SouthPark at Phillips Place, 6700 Phillips Place Court, Charlotte, North Carolina 28210.

Q.

What am I being asked to vote on at the special meeting?

A.

You are being asked to consider and vote on the following:

•: a proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement;
•: a proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger; and
•: a proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to approve the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

Q.

What vote is required for the Company's stockholders to approve the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement?

A.

The approval of the Company Merger pursuant to the terms and conditions set forth in the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Company common stock entitled to vote thereon.

Because the affirmative vote required to approve the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement is based upon the total number of outstanding shares of Company common stock, if you fail to submit a proxy or vote in person at the special meeting, or abstain, or you do not provide your bank, brokerage firm or other nominee with voting instructions, as applicable, this will have the same effect as a vote "AGAINST" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

Q.: What vote is required for the Company's stockholders to approve the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger?
A.: Approval of the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which a quorum is present.

For purposes of this proposal, (i) abstentions will not be counted in tabulating the votes cast, and will not have an effect on the proposal, (ii) broker non-votes will not be counted in tabulating the votes cast, and will not have an effect on the proposal, and (iii) if you fail to submit a proxy or vote in person at the special meeting, the shares of Company common stock not voted will not be counted in respect of, and will not have an effect on, the proposal.

Q.: What is "golden parachute compensation" and what impact will my vote have on the amounts that certain executive officers of the Company will or may receive in connection with the Company Merger?

Table of Contents

A.: "Golden parachute compensation" refers generally to compensation and benefits that executive officers receive as a result of termination of their employment or a change of control of the company. Examples of golden parachute compensation include severance payments to executive officers or the acceleration of equity awards previously granted to those executive officers, including as a result of a sale of the company.

Certain of our executive officers are entitled, pursuant to the terms of their existing compensation arrangements, to receive payments that qualify as golden parachute compensation. If the Company Merger is completed, the Company is obligated to make these payments to these executives under and subject to the terms of existing compensation arrangements, even if the stockholders vote not to approve these payments. The Company is seeking your approval of these payments, on a non-binding advisory basis, in order to comply with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and related SEC rules.

Q.: What vote of our stockholders is required to approve the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies?
A.: Approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which a quorum is present.

For purposes of this proposal, (i) abstentions will not be counted in tabulating the votes cast and will not have an effect on the proposal, (ii) broker non-votes will not be counted in tabulating the votes cast, and will not have an effect on the proposal, and (iii) if you fail to submit a proxy or vote in person at the special meeting, the shares of Company common stock not voted will not be counted in respect of, and will not have an effect on, the proposal.

Q.

Who can vote at the special meeting?

A.

All of our holders of Company common stock of record as of the close of business on February 3, 2012, the record date for the special meeting, are entitled to receive notice of, and to vote at, the special meeting. Each holder of Company common stock is entitled to cast one vote on each matter properly brought before the special meeting for each share of Company common stock that such holder owned as of the record date.

Q.

What is a quorum?

A.

For the transaction of business at the special meeting, the presence, in person or by proxy, of stockholders entitled to cast a majority of all the votes entitled to be cast at the special meeting constitutes a quorum. Abstentions and broker non-votes (if any) are counted as present for the purpose of determining whether a quorum is present.

Q.

How do I vote?

A.

If you are a stockholder of record, you may vote your shares at the special meeting in any of the following ways:

•

in person—you may attend the special meeting and cast your vote there;

•

by proxy—stockholders of record have a choice of authorizing a proxy:

•: over the Internet—the website for Internet proxy authorization is on your proxy card;
•: by using a toll-free telephone number noted on your proxy card; or

Table of Contents

•: by signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope.

If you are a beneficial owner, please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you. Please note that if you are a beneficial owner and wish to vote in person at the special meeting, you must provide a legal proxy from your bank, brokerage firm or other nominee at the special meeting.

A control number, located on your proxy card, is designed to verify your identity and allow you to vote your shares of Company common stock and to confirm that your voting instructions have been properly recorded when authorizing a proxy over the Internet or by telephone. Please be aware that if you authorize a proxy over the Internet, you may incur costs such as telephone and Internet access charges for which you will be responsible.

Q.: What is the difference between holding shares as a stockholder of record and as a beneficial owner?
A.: If your shares of Company common stock are registered directly in your name with our transfer agent, First Shareholder Services, you are considered, with respect to those shares of Company common stock, as the "stockholder of record." This proxy statement and your proxy card have been sent directly to you by the Company.

If your shares of Company common stock are held through a bank, brokerage firm or other nominee, you are considered the "beneficial owner" of shares of Company common stock held in street name. In that case, this proxy statement has been forwarded to you by your bank, brokerage firm or other nominee who is considered, with respect to those shares of Company common stock, the stockholder of record. As the beneficial owner, you have the right to direct your bank, brokerage firm or other nominee how to vote your shares of Company common stock by following their instructions for voting.

Q.: If my shares of Company common stock are held in "street name" by my bank, brokerage firm or other nominee, will my bank, brokerage firm or other nominee vote my shares of Company common stock for me?
A.: Your bank, brokerage firm or other nominee will only be permitted to vote your shares of Company common stock if you instruct your bank, brokerage firm or other nominee how to vote. You should follow the procedures provided by your bank, brokerage firm or other nominee regarding the voting of your shares of Company common stock. If you do not instruct your bank, brokerage firm or other nominee to vote your shares of Company common stock, your shares of Company common stock will not be voted and will have (i) the same effect as a vote "AGAINST" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, (ii) no effect on the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger because broker non-votes (if any) will not be counted in tabulating the votes cast and (iii) no effect on the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies because broker non-votes (if any) will not be counted in tabulating the votes cast.
Q.: How can I change or revoke my vote?
A.: You have the right to revoke a proxy, whether delivered over the Internet, by telephone or by mail, at any time before it is exercised, by authorizing a proxy again at a later date through any of the methods available to you, by giving written notice of revocation to our Corporate Secretary, at

Table of Contents

4401 Barclay Downs Drive, Suite 300, Charlotte, North Carolina 28209, or by attending the special meeting and voting in person.

Q.: What is a proxy?
A.: A proxy is your legal designation of another person, referred to as a "proxy," to vote your shares of Company common stock. The written document describing the matters to be considered and voted on at the special meeting is called a "proxy statement." The document used to authorize a proxy to vote your shares of Company common stock is called a "proxy card." Our board of directors has designated Raymond W. Braun and Charles M. Handy, and each of them, with full power of substitution, as proxies for the special meeting.
Q.: If a stockholder gives a proxy, how are the shares of Company common stock voted?
A.: Regardless of the method you choose to vote, the individuals named on the enclosed proxy card, or your proxies, will vote your shares of Company common stock in the way that you indicate. When completing the Internet or telephone processes or the proxy card, you may specify whether your shares of Company common stock should be voted for or against or to abstain from voting on all, some or none of the specific items of business to come before the special meeting.

If you properly sign your proxy card but do not mark the boxes showing how your shares should be voted on a matter, the shares represented by your properly signed proxy will be voted "FOR" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, "FOR" the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger, and "FOR" the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies.

Q.: What do I do if I receive more than one proxy or set of voting instructions?
A.: If you hold shares of Company common stock in "street name" and also directly as a record holder or otherwise, you may receive more than one proxy and/or set of voting instructions relating to the special meeting. These should each be voted and/or returned separately in accordance with the instructions provided in this proxy statement in order to ensure that all of your shares of Company common stock are voted.
Q.: What happens if I sell my shares of Company common stock before the special meeting?
A.: The record date for stockholders entitled to vote at the special meeting is earlier than both the date of the special meeting and the consummation of the Company Merger. If you transfer your shares of Company common stock after the record date but before the special meeting, unless special arrangements (such as provision of a proxy) are made between you and the person to whom you transfer your shares and each of you notifies the Company in writing of such special arrangements, you will retain your right to vote such shares at the special meeting but will transfer the right to receive the per share merger consideration to the person to whom you transfer your shares.
Q.: Am I entitled to exercise appraisal rights instead of receiving the per share merger consideration for my shares of Company common stock?
A.: No. Holders of Company common stock are not entitled to exercise demand or appraisal rights in connection with the Company Merger.

Table of Contents

Q.: Is the Company Merger contingent upon Ventas obtaining financing?
A.: No. The Company Merger is not conditioned upon Ventas, MergerSub or OP MergerSub obtaining financing. Ventas has informed us that it expects that its cash on hand will be sufficient to complete the acquisition.
Q.: What do I need to do now?
A.: Even if you plan to attend the special meeting, after carefully reading and considering the information contained in this proxy statement, please vote promptly to ensure that your shares are represented at the special meeting. If you hold your shares of Company common stock in your own name as the stockholder of record, please vote your shares of Company common stock by (i) completing, signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope, (ii) authorizing a proxy using the telephone number printed on your proxy card or (iii) authorizing a proxy using the Internet voting instructions printed on your proxy card. If you decide to attend the special meeting and vote in person, your vote by ballot will revoke any proxy previously submitted. If you are a beneficial owner, please refer to the instructions provided by your bank, brokerage firm or other nominee to see which of the above choices are available to you.
Q.: Should I send in my stock certificates now?
A.: No. You will be sent a letter of transmittal promptly, and in any event within five business days, after the completion of the Company Merger, describing how you may exchange your shares of Company common stock for the per share merger consideration. If your shares of Company common stock are held in "street name" by your bank, brokerage firm or other nominee, you will receive instructions from your bank, brokerage firm or other nominee as to how to effect the surrender of your "street name" shares of Company common stock in exchange for the per share merger consideration. Please do NOT return your stock certificate(s) with your proxy.
Q.: Who can help answer my other questions?
A.: If you have additional questions about the Company Merger, need assistance in authorizing your proxy or voting your shares of Company common stock, or need additional copies of the proxy statement or the enclosed proxy card, please call Okapi Partners LLC, our proxy solicitor, which we refer to as Okapi Partners, toll-free at (877) 279-2311.

THE SPECIAL MEETING

Time, Place and Purpose of the Special Meeting

This proxy statement is being furnished to our common stockholders as part of the solicitation of proxies by the board of directors for use at the special meeting to be held on March 9, 2012 at 9:00 a.m., local time, at the Hampton Inn and Suites, SouthPark at Phillips Place, 6700 Phillips Place Court, Charlotte, North Carolina 28210, or at any postponement or adjournment thereof. At the special meeting, holders of Company common stock will be asked to consider and vote on the following:

•: a proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement;
•: a proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger; and
•: a proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies if there are insufficient votes at the time of the special meeting to approve the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

Our stockholders must approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement in order for the Company Merger to occur. If our stockholders fail to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, the Company Merger will not occur. A copy of the merger agreement is attached asAnnex A to this proxy statement, which we encourage you to read carefully in its entirety.

Record Date and Quorum

We have fixed the close of business on February 3, 2012 as the record date for the special meeting, and only holders of record of Company common stock on the record date are entitled to notice of, and to vote at, the special meeting. You are entitled to receive notice of, and to vote at, the special meeting if you owned shares of Company common stock at the close of business on the record date. On the record date, there were 51,237,634 shares of Company common stock outstanding and entitled to vote. Each share of Company common stock entitles its holder to one vote on all matters properly coming before the special meeting.

For the transaction of business at the special meeting, the presence, in person or by proxy, of stockholders entitled to cast a majority of all the votes entitled to be cast at the special meeting constitutes a quorum. Shares of Company common stock for which a stockholder directs an "abstention" from voting, as well as "broker non-votes" (as described below), will be counted for purposes of establishing a quorum. A quorum is necessary to transact business at the special meeting. Once a share of Company common stock is represented at the special meeting, it will be counted for the purpose of determining a quorum at the special meeting and any adjournment or postponement of the special meeting. However, if a new record date is set for the adjourned or postponed special meeting, then a new quorum will need to be established. In the event that a quorum is not present at the special meeting, it is expected that the special meeting will be adjourned or postponed.

Attendance

Only Company common stockholders of record or their duly authorized proxies have the right to attend the special meeting. To gain admittance, you must present valid photo identification, such as a driver's license or passport. If your shares of Company common stock are held through a bank, brokerage firm or other nominee, please bring to the special meeting a copy of your brokerage statement evidencing your beneficial ownership of Company common stock and valid photo

identification. If you are the representative of a corporate or institutional stockholder, you must present valid photo identification along with proof that you are the representative of such stockholder. Please note that cameras, recording devices and other electronic devices will not be permitted at the special meeting.

Vote Required; Impact of Not Voting, Abstentions and Broker Non-Votes

Company Merger. Approval of the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement requires the affirmative vote of the holders of a majority of the outstanding shares of Company common stock entitled to vote thereon. For the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, you may voteFOR, AGAINST or ABSTAIN.

Abstentions will not be counted as votes cast in favor of the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement but will be counted for the purpose of determining whether a quorum is present.If you fail to authorize a proxy or to vote in person at the special meeting, or abstain, it will have the same effect as a vote "AGAINST" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

If your shares of Company common stock are registered directly in your name with our transfer agent, First Shareholder Services, you are considered, with respect to those shares of Company common stock, the "stockholder of record." This proxy statement and proxy card have been sent directly to you by the Company.

Under the rules of the NYSE, banks, brokerage firms or other nominees who hold shares in street name for customers have the authority to vote on "routine" proposals when they have not received instructions from beneficial owners. However, banks, brokerage firms or other nominees are precluded from exercising their voting discretion with respect to approving non-routine matters (such as the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger, and the proposal to adjourn the special meeting, if necessary or appropriate, to solicit additional proxies) and, as a result, absent specific instructions from the beneficial owner of such shares of Company common stock, banks, brokerage firms or other nominees are not empowered to vote those shares of Company common stock on non-routine matters, which we refer to generally as broker non-votes.These broker non-votes (if any) will be counted for purposes of determining a quorum, but will have the same effect as a vote "AGAINST" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

Advisory Vote on Golden Parachute Compensation. Approval of the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which a quorum is present. For the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger, you may voteFOR, AGAINST or ABSTAIN.

Table of Contents

For purposes of this proposal, abstentions will not be counted in tabulating the votes cast and will not have an effect on the proposal. Broker non-votes also will not be counted in tabulating the votes cast, and will not have an effect on the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger. If you fail to authorize a proxy or vote in person at the special meeting, the shares of Company common stock not voted will not be counted in respect of, and will not have an effect on, the proposal to approve, on a non-binding advisory basis, the compensation that certain executive officers of the Company will or may receive in connection with the Company Merger.

Adjournment to Solicit Additional Proxies. Approval of the proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which a quorum is present. For the proposal to adjourn the special meeting, if necessary or appropriate, you may voteFOR, AGAINST or ABSTAIN.

For purposes of this proposal, abstentions will not be counted in tabulating the votes cast, and will not have an effect on the proposal. Broker non-votes also will not be counted in tabulating the votes cast, and will not have an effect on the proposal to adjourn the special meeting. If you fail to authorize a proxy or vote in person at the special meeting, the shares of Company common stock not voted will not be counted in respect of, and will not have an effect on, the proposal to adjourn the special meeting.

Proxies and Revocation

Any Company common stockholder of record entitled to vote at the special meeting may authorize a proxy by telephone, over the Internet or by returning the enclosed proxy card in the accompanying prepaid reply envelope, or may vote in person at the special meeting. If your shares of Company common stock are held in "street name" by your bank, brokerage firm or other nominee, you should instruct your bank, brokerage firm or other nominee on how to vote your shares of Company common stock using the instructions provided by your bank, brokerage firm or other nominee. If you fail to authorize a proxy or vote in person at the special meeting, or abstain, or do not provide your bank, brokerage firm or other nominee with voting instructions, as applicable, your shares of Company common stock will not be voted on the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, which will have the same effect as a vote "AGAINST" the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement.

Table of Contents

You have the right to revoke a proxy, whether delivered over the Internet, by telephone or by mail, at any time before it is exercised, by authorizing a proxy at a later date through any of the methods available to you, by giving written notice of revocation to our Corporate Secretary, which must be filed with the Company at 4401 Barclay Downs Drive, Suite 300, Charlotte, North Carolina 28209 by the time the special meeting begins, or by attending the special meeting and voting in person. If your shares of Company common stock are held in "street name" by your bank, brokerage firm or other nominee, please follow the instructions you receive from you bank, brokerage firm or other nominee to change your vote.

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed, including for the purpose of soliciting additional proxies, if there are insufficient votes at the time of the special meeting to approve the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement or if a quorum is not present at the special meeting. Other than an announcement to be made at the special meeting of the time, date and place of an adjourned meeting, an adjournment generally may be made without notice if the meeting is adjourned to a date no more than 120 days after the original record date in accordance with the Company's bylaws. Any adjournment or postponement of the special meeting for the purpose of soliciting additional proxies will allow the Company's stockholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned or postponed.

Anticipated Date of Completion of the Company Merger and Related Transactions

We are working towards completing the Company Merger as soon as possible. Assuming timely satisfaction of necessary closing conditions, including the approval by our stockholders of the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, we anticipate that the Company Merger and related transactions will be completed during the second quarter of 2012.

Solicitation of Proxies; Payment of Solicitation Expenses

The Company has engaged Okapi Partners to assist in the solicitation of proxies for the special meeting. The Company estimates that it will pay Okapi Partners a fee not to exceed approximately $35,000, plus fees per each call made to or received from stockholders of the Company. The Company will reimburse Okapi Partners for reasonable out-of-pocket expenses and will indemnify Okapi Partners and its affiliates against certain claims, liabilities, losses, damages and expenses. The Company may also reimburse brokers, banks and other custodians, nominees and fiduciaries representing beneficial owners of shares of Company common stock for their expenses in forwarding soliciting materials to beneficial owners of Company common stock and in obtaining voting instructions from those owners. Our directors, officers and employees may also solicit proxies by telephone, by facsimile, by mail, on the Internet or in person. They will not be paid any additional amounts for soliciting proxies.

Householding

SEC rules permit us, with your permission (including, in certain circumstances, your implied permission), to send a single proxy statement to any household at which two or more stockholders reside if we believe that they are members of the same family. Each stockholder will continue to receive a separate proxy card. This procedure, known as householding, reduces the volume of duplicate information you receive and helps to reduce our expenses. In order to take advantage of this opportunity, we have delivered only one proxy statement to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. If you prefer to receive separate copies of a proxy statement, either now or in the future, you can

request a separate copy of the proxy statement by calling us at (704) 940-2900 or by writing to us at any time at the following address: Cogdell Spencer Inc., 4401 Barclay Downs, Suite 300, Charlotte, North Carolina 28209, attn: Corporate Secretary. Additionally, stockholders sharing an address can request delivery of a single copy of the proxy statement if they are receiving multiple copies of the proxy statement by calling us at (704) 940-2900 or by writing to us at any time at the following address: Cogdell Spencer Inc., 4401 Barclay Downs Drive, Suite 300, Charlotte, North Carolina 28209, attn: Corporate Secretary.

THE COMPANY MERGER

This discussion of the Company Merger is qualified in its entirety by reference to the merger agreement, which is attached to this proxy statement asAnnex A. You should read the entire merger agreement carefully as it is the legal document that governs the Company Merger.

General

The merger agreement provides that either (i) MergerSub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of Ventas, or (ii) the Company will merge with and into MergerSub, with MergerSub surviving as a wholly-owned subsidiary of Ventas. As a result of the Company Merger, the Company will cease to be a publicly traded company. Regardless of the manner in which the Company Merger is structured, you will not be entitled to own any shares of the capital stock of the Surviving Company after the Company Merger is completed. Additionally, pursuant to the merger agreement, OP MergerSub will merge with and into the Operating Partnership, with the Operating Partnership surviving as a wholly-owned subsidiary of Ventas. Only the Company Merger contemplated by the merger agreement is being submitted to a vote of the holders of Company common stock. However, if the Company Merger is not approved by the stockholders of the Company, the Partnership Merger will not be completed.

In the Company Merger, each outstanding share of Company common stock (other than the excluded shares) will be converted into the right to receive $4.25 in cash, without interest, which amount we refer to as the per share merger consideration, less any applicable withholding taxes. The Company has paid its currently declared common stock dividend as scheduled on January 19, 2012 to the holders of record of our common stock as of the close of business on December 27, 2011. The Company will not pay further dividends on Company common stock pending consummation of the transactions contemplated by the merger agreement.

Additionally, in connection with the Company Merger, each outstanding share of the Company's Series A Preferred Stock (other than the excluded preferred shares) will be converted into the right to receive $25.00 in cash, plus all accrued and unpaid dividends thereon through and including the date of the Company Merger, without interest, which amount we refer to as the preferred per share merger consideration, less any applicable withholding taxes. In connection with the Company Merger, each OP Unit (other than OP Units owned directly or indirectly, by the Company or any of the Company's wholly-owned subsidiaries), other than LTIP Units, will be converted into the right to receive the per share merger consideration without interest, less any applicable withholding taxes. Immediately before the effective time of the Partnership Merger, each unvested LTIP Unit granted under the Operating Partnership's long-term incentive plans or otherwise that is outstanding at such time will become fully vested and each vested LTIP Unit will automatically convert into an OP Unit, or fraction thereof, based on the adjusted capital account balance allocable to such LTIP Unit immediately prior to the Partnership Merger; accordingly, holders of LTIP Units that are so converted generally will receive the per share merger consideration, without interest, less any applicable withholding taxes.

Background of the Company Merger

As part of its ongoing consideration and evaluation of the Company's long-term prospects and strategies, the Company's board of directors and senior management have regularly reviewed and assessed the Company's business strategies and objectives, including strategic opportunities and challenges, all with the goal of enhancing stockholder value.

Soon after the Company's March 2008 acquisition of the Marshall Erdman design-build business, also referred to as the Erdman business, a series of negative events in the financial sector occurred, which later induced paralysis in the credit markets and ushered in the deepest economic recession in decades. The credit crisis and economic recession have had a disproportionately negative impact on the

Table of Contents

commercial real estate industry, including particularly the demand for construction of new medical properties. Many of the projects in Erdman's pipeline were put on hold indefinitely or canceled permanently.

As a result of the difficult operating environment, in December 2008, the Company announced its 2009 business strategy, which included a cost saving plan that was intended to reduce costs and preserve capital for productive deployment while allowing the Company to continue to pursue its integrated delivery strategy despite client-related project delays resulting from the financial crisis. As part of that plan, the Erdman business implemented a reduction in force that eliminated approximately 115 jobs and the Company announced a reduction in the quarterly dividend from $0.35 per common share to $0.225 per common share, beginning with the fourth quarter of 2008.

Business conditions continued to deteriorate in early 2009. In May 2009, the Company reported a $101.7 million, or $3.79 per share, after-tax impairment charge related to the Erdman business, reduced its full-year guidance for Funds from Operations Modified, or FFOM, by approximately 20%, and further reduced the quarterly dividend by over 50%. The Company was able to raise approximately $76.5 million of equity capital through a public offering of 23.0 million shares of common stock at $3.50 per share, the proceeds of which were used to repay existing indebtedness and bolster the Company's working capital.

In the fourth quarter of 2009, the Company initiated a strategic review with assistance from its former financial advisor. After assessing a number of factors, including the then-current market environment (including continued economic weakness and turmoil in the capital markets), the Company's capital position and leverage, and the status of efforts to integrate the Erdman design-build platform, the Company's board of directors initiated a process to determine whether sale of the Company at that time would be in the best interests of the Company and its stockholders. As part of that process, the Company approached ten strategic buyers (including Ventas) and four financial sponsors to gauge their interest in a potential acquisition of the Company. The Company received preliminary indications of interest for all or part of the Company from five strategic buyers, including Ventas. By early 2010, however, the Company was negotiating only with Ventas, as the other four buyers either affirmatively withdrew from the process or declined to submit a final round bid. At the time negotiations with Ventas ended in February 2010, the parties were discussing a potential stock-for-stock merger; however, material terms of the acquisition remained unresolved, and the Company was not able to reach agreement with Ventas. The Board concluded that conditions for a sale of the Company were not favorable at that time and decided to instead pursue a strategy to operate independently.

In May 2010, the Company announced the retirement of Frank Spencer as president and chief executive officer by the fourth quarter of 2010. In September 2010, the Company announced the hiring of Ray Braun to serve as president and chief executive officer.

During the period from May 2010 to the summer of 2011, the Company took various measures to bolster its balance sheet, including (1) raising net proceeds of approximately $47.1 million of additional common equity capital through a public offering of 7.1 million shares of common stock at $7.00 per share, (2) raising net proceeds of approximately $71.2 million of additional equity capital through a public offering of Series A cumulative redeemable perpetual preferred stock, (3) amending its revolving credit facility to increase the maximum borrowing amount from $150 million to $200 million (plus up to an additional $150 million in an "accordion" feature) and to extend the maturity date to March 2014 (with the option to extend for an additional year), and (4) entering into an $80.8 million term loan, the proceeds of which were used primarily to refinance mortgage debt that was maturing in 2011 and 2012.

In March 2011, the Company announced a strategic plan to grow assets through acquisitions and new developments. The Company also planned to grow revenues by increasing third-party design-build

contract volumes. The strategic plan assumed new assets would be financed with a mix of debt and common equity.

Also in March 2011, the Company announced a $93.8 million after-tax impairment charge and established a $10.6 million deferred tax asset valuation allowance, both relating to the Erdman business. The Company also announced 2011 full-year FFOM guidance in the range of $0.33 to $0.40 per share (excluding impairments or other capital transactions). However, after the first quarter, the Company revised its annual FFOM guidance to be in the range of $0.30 to $0.33 per share.

Consistent with the strategic plan described above, the Company explored numerous opportunities for acquisitions and new developments. However, by August 2011, following the release of revised FFOM guidance noted above and second quarter earnings, the Company's common stock was trading at prices that would make further equity capital raises highly dilutive to existing stockholders, and the Company had limited capacity to obtain additional debt financing.

On October 6, 2011, the Company's board of directors held a conference call to receive an update on the Company's operations and progress against its strategic plan. Management reported that the Company's strategic plan depended on the ability to raise capital but that the current stock price would not allow a capital raise except on highly dilutive terms and the Company's existing leverage levels were already high. The Company's chief executive officer reported that he had received joint venture inquiries from two prospective partners, but recommended that the Company undertake a careful evaluation of all of its strategic options. The board requested that management explore with outside advisors a range of potential strategic alternatives to be reported to the board at a follow-up meeting.

Following the October 6, 2011 meeting, management of the Company conducted a more comprehensive review of the ability of the Company to execute on its strategic plan in light of its liquidity position and limited ability to raise capital, among other factors, and compared its strategic plan against other potential alternatives, including a sale of the Company or pursuit of joint venture capital for development.

On October 14, 2011, the Company's board of directors met to discuss these potential strategic alternatives with management. The board reconvened for further discussion at a meeting on October 19, 2011, which was also attended by management and the Company's financial advisor, Citigroup Global Markets Inc., or Citi. At the October 19, 2011 meeting, management presented its analysis of the Company's cash needs and budget forecasts to pursue its strategic plan and compared these to other potential strategic alternatives, including a hypothetical equity raise and a certain level of joint venture activity. Citi discussed with the board matters relating to the current financial and operating environment and potential joint venture alternatives and other scenarios. Although the board did not make a determination to pursue a sale at this meeting, the board noted that many of the other alternatives that the Company might explore were not likely to address concerns relating to the Company's ability to raise capital at attractive valuations, reduce its leverage, or improve its liquidity.

At its regularly scheduled meeting held on November 2 and 3, 2011, with management and representatives of the Company's outside legal counsel, Alston & Bird LLP, and Citi present, the board reviewed management's assessment of the Company's current challenges, opportunities, and alternative strategies and the status of the Company's forward-looking business plan. The board discussed with Citi on a preliminary basis the Company's liquidity position and various scenarios, including an equity capital raise and funding of development projects through joint ventures, and the potential financial impact of continued limited access to capital. Taking into consideration the Company's high leverage, liquidity position and limited access to equity capital, the board concluded that a sale of the Company should be considered as a way to maximize value for stockholders. The board then reviewed with management, Alston & Bird and Citi sale process alternatives, including a negotiated sale to a single party, a controlled process involving a select number of potential acquirers, and a fully-disclosed public auction. Alston & Bird also reviewed with the directors their duties under applicable law. Following an

Table of Contents

executive session of the independent directors, the board authorized the commencement of a confidential process to determine the potential interest of a select number of potentially interested parties, including seven strategic buyers (including Ventas) and five financial sponsors that the board, in consultation with management and Citi, deemed most likely to have significant interest in, and ability to consummate, an acquisition of the Company.

Following the conclusion of the board meeting on November 3, 2011, the Company commenced preparation of a confidential information memorandum and assembled materials to facilitate due diligence investigations by prospective bidders. Beginning on November 16, 2011, prospective bidders were contacted to invite them to enter into non-disclosure agreements.

Shortly thereafter, three strategic buyers and one financial buyer indicated that they were declining to participate in the process and would not be executing non-disclosure agreements. Each of the remaining eight prospective buyers (including four strategic buyers and four financial buyers) executed non-disclosure agreements with the Company and received access to the Company's due diligence materials. Ventas and two other bidders were the first to receive access on or about November 18, 2011, with the other bidders finalizing non-disclosure agreements and receiving access over the next 7 to 10 days.

In the course of negotiating non-disclosure agreements, one financial sponsor asked for and received permission from the Company to partner with another financial institution with experience in the industry, subject to execution of a separate non-disclosure agreement. The proposed partner declined to execute a non-disclosure agreement and neither it nor the financial sponsor ultimately submitted an indication of interest.

Between November 18, 2011 and through the execution of the merger agreement on December 24, 2011, Ventas continued to conduct a substantial due diligence review of the Company and its business.

On November 29, November 30, and December 1, 2011, five of the bidders that had executed non-disclosure agreements participated in management presentations with the Company. Also during this week, one of the financial sponsors requested permission to partner with a strategic industry partner that was not initially included in the Company's process. This financial sponsor was informed that its proposed strategic partner would be provided access to due diligence materials and included in management presentations upon execution of its own non-disclosure agreement. However, the proposed strategic partner did not execute a non-disclosure agreement and therefore did not attend management presentations with the financial sponsor. This financial sponsor ultimately conducted only limited due diligence and declined to submit an indication of interest.

On November 28 and 29, 2011, a process letter was distributed to bidders. The letter emphasized the need for bidders to finalize due diligence on a timely basis and submit indications of interest not later than 5:00 p.m. EST on December 9, 2011, with the goal of completing and announcing a transaction prior to the Christmas holiday. During this period, the Company, with Citi's assistance, continued to monitor and coordinate the due diligence efforts of those bidders engaged in the process. Concurrently with the bidder due diligence efforts, Alston & Bird and the Company prepared a draft merger agreement and associated draft disclosure schedules.

On December 2, 2011, the chief executive officer of one of the strategic bidders included in the Company's process requested a meeting with the Company's chief executive officer. The Company's chief executive officer and financial advisor met with this person on the evening of December 5, 2011. At that meeting, the chief executive officer of the bidder expressed the bidder's significant interest in pursuing a transaction with the Company but noted significant concern about acquiring the Erdman business and that the bidder ultimately expected that, if it did submit an indication of interest, its bid would be at or around $4.00 per share.

On December 9, 2011, in accordance with the Company's instructions, Ventas and one other strategic bidder, which we refer to as the Competing Bidder, submitted written indications of interest. Ventas proposed to acquire the Company for cash, at a price in the range of $4.60 to $5.10 per share, based on certain assumptions and with assurances that the transaction would not be contingent on financing. The Competing Bidder proposed an offer of $5.25 per share in cash, with similar assumptions and also without a financing contingency. In their written indications of interest, both Ventas and the Competing Bidder stated that, as a condition to completing the transaction, the Company would be required to divest the Erdman business prior to closing, on terms that would not have any material adverse impact on the Company's remaining assets and business.

Two other bidders also had completed substantial due diligence. One indicated that it would only be interested in acquiring the Company at a price that would have been in the range of the last trading price of the Company's common stock, or approximately $3.80 per share. The other bidder (with which the Company's chief executive officer and financial advisor met on December 5, 2011) indicated it would be interested only in a merger-of-equals structure, also at no premium to the Company's then-prevailing market price. Both also indicated that they had significant concerns about acquiring the Company if it included the Erdman business. After being informed that the Company would likely have limited interest in a transaction at the levels they had indicated, these two bidders declined to submit written indications of interest.

On December 10, 2011, the board convened to consider the proposals, with management and the Company's advisors present. The board was informed of the condition reflected in both indications of interest that the Erdman business be disposed as a condition to proceeding with the larger transaction, which also had been confirmed in verbal discussions with each of Ventas and the Competing Bidder. The board discussed and considered a number of alternatives for the disposition of the Erdman business, including a spin-off of the Erdman business to the Company's stockholders, liquidation or bankruptcy of the Erdman business, the sale of the Erdman business or, in the alternative, restructuring the proposed transaction as a sale of the Company's real estate assets with the Erdman business and the proceeds of the sale to remain as Company assets. The board weighed the alternatives in light of the projected short-term losses of the Erdman business anticipated by management and the likelihood that the Company would be required to fund these losses to satisfy the requirement expressed by the bidders that the disposition occur in a fashion that did not otherwise adversely impact the Company or its business, with a goal of identifying a solution that would minimize costs to the Company and would also provide a high degree of certainty with respect to the ability of the Company to complete the larger transaction.

During the course of these discussions, David Lubar, a member of the board and a former principal in the Erdman business, indicated a willingness to consider making a proposal to purchase the Erdman business. Mr. Lubar stated that key terms of a transaction he would consider would likely include a nominal purchase price for the Erdman business and approximately equal commitments from both the Company and the Erdman buyer to fund projected working capital needs of the Erdman business over the following 12 months. At this point and in light of the conflict of interest presented by his role as a potential purchaser of the Erdman business, Mr. Lubar was excused from further deliberations regarding the proposed sale of the Company. Mr. Lubar did not participate in subsequent discussions of the board regarding the transaction with Ventas or any other bidder or the disposition of the Erdman business. Mr. Lubar subsequently resigned from the board on January 5, 2012.

Following Mr. Lubar's departure from the December 10, 2011 meeting, the board continued discussions of the bids received by each of Ventas and the Competing Bidder and authorized management, with the assistance of the Company's legal and financial advisors, to continue the process with each of Ventas and the Competing Bidder and to begin negotiating terms of a proposed sale of the Erdman business to Mr. Lubar. The board indicated that the sale of the Erdman business to Mr. Lubar would need to include the ability of the Company to solicit additional proposals for the

Erdman business following the announcement of the transaction (a process often referred to as "go-shop"), with any incremental net proceeds received from that sale to be available for distribution to the Company's stockholders. Immediately following the meeting, each of Ventas and the Competing Bidder were provided with instructions for submission of their final bids, due December 16, 2011, as well as a draft of the merger agreement.

Following the meeting and over the remaining portion of the December 10^th weekend, the Company's chief executive officer and advisors commenced discussions with Mr. Lubar and his representatives regarding the potential disposition of the Erdman business on an "as-is, where-is" basis. The board's expectations regarding the terms of the sale were reiterated to Mr. Lubar, including that, in light of the conditions expressed by both remaining bidders with respect to the disposition of Erdman, any buyer of the Erdman business would be required to assume a high degree of risk related to both its historical and prospective operations. At Mr. Lubar's request, the Company authorized Brian Happ, the Chief Operating Officer of the Erdman business, to work with Mr. Lubar with respect to his proposal to acquire the Erdman business. Alston & Bird commenced preparation of the Erdman purchase agreement, which was subsequently distributed to Mr. Lubar on December 13, 2011.

On December 12, 2011, representatives of Ventas and the Competing Bidder each contacted the Company to discuss the proposed terms of the disposition of the Erdman business, as well as other matters relating to the structure of the Company Merger and the Partnership Merger. Each of Ventas and the Competing Bidder indicated that they were continuing to conduct due diligence of the Company and the Erdman business and were continuing to explore alternative structures. The Competing Bidder also raised the possibility of acquiring only the Company's real estate assets, but the Competing Bidder did not propose a price for such a transaction at that time.

On December 13, 2011, the Company and its advisors met with Mr. Lubar to discuss estimates of projected working capital necessary for the Erdman business to operate on a standalone basis, driven largely by bonding requirements for the construction industry and projected operating losses at Erdman through the next 9 to 12 months. In that discussion, Mr. Lubar proposed that the Company contribute an additional $20 million to supplement projected working capital of the Erdman business as of the anticipated closing date, while he would contribute an additional $10 million, with other terms and conditions substantially similar to those offered by the Company, including the requirement that the transaction be subject to a go-shop provision.

On December 14, 2011, the board conducted a telephonic meeting convened for the purpose of updating the board on the status of discussions with Mr. Lubar and whether there were other more compelling alternatives for the disposition of the Erdman business, including a spin-off, orderly liquidation, wind-down or bankruptcy. The board determined that several of these alternatives would likely be unacceptable to bidders for the Company, and that others would require equal or greater contributions from the Company to fund projected losses at Erdman. Following discussion, the board authorized management, with the assistance of the Company's advisors, to continue discussions with Mr. Lubar. Later that day, a counterproposal consistent with the board's directions was communicated to Mr. Lubar.

Negotiations continued with Mr. Lubar, and after several rounds of discussion on December 14 and 15, 2011, Mr. Lubar and the Company tentatively agreed to contributions of approximately $12 million each to fund additional working capital needs of the Erdman business, along with the elimination of certain intercompany indebtedness and other terms and conditions generally consistent with those initially proposed by the Company.

Following conclusion of these discussions with Mr. Lubar on December 15, 2011, each of Ventas and the Competing Bidder were informed that the Company had negotiated the material terms for the disposition of the Erdman business to Mr. Lubar on an "as-is, where-is" basis. The bidders also were informed that they should submit best and final offers by the December 16, 2011 deadline on the

assumption that the Erdman business would be disposed of at no incremental cost. The bidders were not informed at this time of the anticipated $12 million contribution of working capital to the Erdman business, although the board anticipated this would require a subsequent reduction in their bids commensurate with the amount of the contribution (equal to approximately $0.20 per share).

On December 16, 2011, Ventas submitted its written proposal to acquire the Company for $4.60 per share, subject to various assumptions regarding liabilities of the Company and the terms of the disposition of the Erdman business. Together with its bid, Ventas submitted its initial revisions to the draft merger agreement. Notwithstanding its initial indication of interest at $5.25, the Competing Bidder declined to submit a written proposal. In accordance with the Company's directives, Citi contacted the Competing Bidder, which instead expressed an interest in a potential acquisition of real estate assets of the Company, and indicated that it would be willing to submit a formal proposal on that basis.

The board convened telephonically on the morning of December 17, 2011. The board was informed of the terms of the Ventas proposal and the potential that the final purchase price could be substantially below the nominal $4.60 price indicated in the Ventas proposal because of key assumptions set forth in the proposal and the merger agreement revisions, including assumptions relating to the Company's cash flows and indebtedness and the terms of any disposition of the Erdman business. The board was also informed of the decision of the Competing Bidder not to submit a final proposal consistent with the Company's process letter and the expressed willingness of the Competing Bidder to instead consider a sale of the Company's real estate assets at a potentially more attractive valuation than the Competing Bidder would offer in an all-cash merger. The board instructed management, with the assistance of the Company's advisors, to attempt to quantify anticipated transaction costs, liabilities under certain contractual obligations of the Company, and anticipated expenses associated with a disposition of the Erdman business to determine the likely range of net proceeds for the Company's stockholders that an asset-sale transaction might yield, as those obligations would not be assumed by the prevailing bidder in connection with an asset sale. The board then authorized the solicitation of revised proposals from each of Ventas and the Competing Bidder on that basis and scheduled a follow-up board call for the afternoon of December 18, 2011 to consider the revised proposals and management's analysis of the anticipated transaction costs. Following the meeting, representatives of Mr. Lubar were informed that the Company was exploring other alternatives that would not involve the immediate sale of the Erdman business.

On the afternoon of December 17, 2011, each of Ventas and the Competing Bidder were contacted to obtain a projected purchase price for the Company's real estate assets. Ventas declined to submit an asset-only proposal but clarified certain elements of its earlier proposal, including elimination of some conditions that the Company perceived might have otherwise adversely impacted the purchase price or the likelihood of closing. The Competing Bidder submitted two written asset-only proposals, on December 17 and 18, 2011, but in each case only at implied per share prices that would be below the most recent closing price of the Company's common stock, $3.60 per share, after accounting for transaction costs and other liabilities and expenses that would have to be discharged before the net proceeds were available for distribution to the Company's stockholders. In its discussions with the Company's financial advisor, the Competing Bidder highlighted the Company's liquidity position, leverage and market capitalization as impediments to the Company's ability to execute its operating strategy that the Competing Bidder believed justified the lower bid.

At 5:00 p.m. on December 18, 2011, the board reconvened for an update, with management and the Company's advisors present. Citi informed the board of the Competing Bidder's proposal. The board also discussed with Citi financial aspects of Ventas's clarified proposal of $4.60 per share, including the proposed valuation implied for the Company's real estate portfolio, especially when considered in light of the Company's liquidity position and prospects, the potential dilutive impact of equity capital raises, the uncertain prospects for the Erdman business, whether on a standalone basis or

as part of the Company, and the current terms of Mr. Lubar's proposal to acquire the Erdman business. The board discussed the Ventas and Erdman sale proposals at length and authorized management, with the assistance of the Company's advisors, to proceed with negotiations with Ventas and to recommence discussions with Mr. Lubar.

Following the board meeting, the Company contacted representatives of Mr. Lubar to advise them that the transaction would likely proceed with one of the bidders and of the anticipated timetable for execution of definitive agreements. The following morning, in accordance with the Company's directives, Citi informed Ventas and its financial advisors, Centerview Partners, LLC, or Centerview, and Morgan Stanley & Co. LLC, or Morgan Stanley, of the Company's decision to proceed with discussions with Ventas. Representatives of the parties discussed at this time the $0.20 per share deduction to the purchase price in light of the anticipated contributions by the Company of approximately $12 million to fund the liquidity needs of the Erdman business. Alston & Bird distributed revised drafts of the Erdman purchase agreement and related documents to counsel for Mr. Lubar and also provided those documents to Willkie Farr & Gallagher LLP, or Willkie Farr, counsel to Ventas, for its initial review and comment.

Alston & Bird and Willkie Farr exchanged drafts of the merger agreement reflecting comments from the Company and Ventas, respectively, early in the morning of December 20, 2011, and again later that evening. Representatives of each of Ventas and the Company commenced telephonic negotiations of the merger agreement and also engaged in three-party discussions with Mr. Lubar and his counsel regarding the terms of the Erdman purchase agreement. These discussions continued throughout the evening of December 20, 2011 and into December 21, 2011.

On December 21, 2011, at the request of Ventas, the chief executive officer of the Company and a representative of Citi met with Ventas representatives, including representatives from Centerview and Morgan Stanley, in Chicago, with Alston & Bird, Willkie Farr and certain other representatives of Citi participating telephonically, to discuss operational matters relating to the extent of integration of the Company and the Erdman companies and the proposed terms of the separation. Following conclusion of the larger session, Ventas communicated its position regarding certain other key terms of the transaction, including its insistence on certain break-up fees and expense reimbursement provisions in the case of termination of the merger agreement and its willingness to remove certain closing conditions Ventas previously had requested. Ventas also indicated that there might be additional purchase price adjustments based on the Company's cash position through closing, but did not provide any additional detail at that time.

Discussions between representatives of Ventas, the Company and Mr. Lubar to finalize the terms of the merger agreement, the Erdman purchase agreement and related transaction documents continued throughout the day on December 22, 2011. Late in the afternoon on December 22, 2011, Willkie Farr distributed a revised draft of the merger agreement reflecting, among other changes, the terms and conditions indicated by Ventas on December 21, 2011. Ventas and Willkie Farr continued to conduct substantial due diligence on the Erdman business, and engaged in extended discussions with Alston & Bird and counsel to Mr. Lubar regarding the terms of the Erdman purchase agreement and related transaction documents.

At 9:00 pm EST on the evening of December 22, 2011, the board of the Company convened telephonically to consider the terms of the proposed transactions with Ventas and the Erdman buyer. Management and the Company's outside advisors updated the board on the status of negotiations with Ventas and the Erdman buyer, after which Alston & Bird discussed with the board key terms and conditions of the merger agreement and the Erdman purchase agreement, which had previously been circulated to the board. Alston & Bird also reviewed again the directors' duties under applicable law. Citi reviewed with the Company's board of directors financial aspects of the proposed transaction with Ventas, after which the independent directors convened in executive session to further consider the

proposed transactions. At the conclusion of the executive session, the Company's chief executive officer and advisors rejoined the call, and the board authorized moving forward to finalize the merger agreement with Ventas at $4.40 per share and to finalize the Erdman purchase agreement on the terms outlined for the board.

Following the board meeting, Willkie Farr and Alston & Bird continued negotiations to finalize the merger agreement. At approximately 12:45 a.m. on the morning of December 23, 2011, Ventas's chief executive officer communicated to Cogdell's chief executive officer that it had, as previously discussed, finished analyzing the Company's expected future cash flows, and, in light of this review, Ventas was proposing a purchase price of $4.10 per share. In light of the reduction in price, the Company ceased discussions with Ventas regarding the merger agreement.

On the morning of December 23, 2011, the Company's chief executive officer directed the Company's advisors to resume discussions with Ventas and Willkie Farr to finalize the merger agreement, subject to final resolution of price discussions. In the meantime, Ventas was provided further information regarding the Company's projected balance sheet and expected future cash flows. Shortly after 12:00 noon, after further negotiations, the Company and Ventas agreed upon a price of $4.25 per share.

At approximately 2:00 p.m. on December 23, 2011, Alston & Bird distributed a revised draft of the merger agreement to Willkie Farr reflecting the Company's comments. Also on the afternoon of December 23, 2011, representatives of Ventas and Mr. Lubar continued negotiations over the terms of the release and indemnification to be provided by the Erdman purchaser to the Company under the terms of the Erdman sale, which was the primary remaining open issue on the terms of the Erdman sale.

At approximately 5:00 p.m. on the afternoon of December 23, 2011, Willkie Farr provided to Alston & Bird further comments on the draft merger agreement.

At 5:30 p.m. on December 23, 2011, the board of directors received updates from the Company's chief executive officer and advisors regarding the status of negotiations of both transactions and the most recent proposed changes to the merger agreement. Also at this meeting, Citi reviewed with the Company's board of directors its financial analysis of the $4.25 per share merger consideration to be received in the Company Merger and rendered to the board an oral opinion, confirmed by delivery of a written opinion dated December 23, 2011, to the effect that, as of that date and based on and subject to the various assumptions and limitations set forth in its opinion, the $4.25 per share merger consideration to be received in the Company Merger by holders of Company common stock was fair, from a financial point of view, to such holders. After further discussion and deliberation, the board of directors, having determined that the Company Merger was advisable and in the best interests of the Company and its stockholders, unanimously approved and declared advisable and in the best interests of the Company and its stockholders the Company Merger, on substantially the terms and conditions set forth in the merger agreement, directed that the Company Merger be submitted to the Company's stockholders for approval, and recommended that stockholders vote in favor of the approval of the Company Merger on substantially the terms and conditions set forth in the merger agreement. Further, the board of directors unanimously deemed the entry into the Erdman purchase agreement advisable and in the best interests of the Company and its stockholders and approved the entry into the Erdman purchase agreement.

Following the board meeting, the parties finalized the terms of the merger agreement. Early the following morning, on December 24, 2011, the Company and Ventas executed the merger agreement, and the Company and the Erdman buyer executed the Erdman purchase agreement. Prior to market open on December 27, 2011, the proposed transactions were publicly announced.

Reasons for the Company Merger; Recommendation of the Board of Directors

At a meeting held on December 23, 2011, the board of directors, other than Mr. Lubar (who, as noted above, was excluded from, and did not participate in, deliberations regarding the Company Merger, the merger agreement and related transactions commencing with the December 10, 2011 board meeting), unanimously approved and declared advisable and in the bests interests of the Company and its stockholders the Company Merger, on substantially the terms and conditions set forth in the merger agreement, directed that the Company Merger be submitted to the Company's stockholders for approval, and recommended that stockholders vote in favor of the approval of the Company Merger on substantially the terms and conditions set forth in the merger agreement.

In evaluating the Company Merger, the merger agreement, and the other transactions contemplated by the merger agreement, including the Erdman sale, the board of directors consulted with our senior management team, as well as the Company's outside legal and financial advisors, and considered a number of factors, including the following material factors:

•: the board of directors' understanding of the business, operations, financial condition, earnings and prospects of the Company, including the Company's prospects as an independent entity, and management's and the board of directors' views and opinions on the current state of the REIT industry;
•: current impediments to the Company's ability to raise capital and the Company's current liquidity position, each of which would present significant challenges to the Company's ability to execute alternative strategies as an independent company;
•: the board of directors' belief that the separation of Erdman from the Company was necessary to effectuate the Company Merger;
•: the board of directors' assessment of projected working capital requirements for the Erdman business, which the board believed would need to be funded in order to effectuate most or all of the plausible alternatives to separate Erdman from the Company, and that the sale of the Erdman business pursuant to the Erdman purchase agreement results in a material portion of those contributions from the buyer of the Erdman business;
•: the board of directors' belief that the Company Merger is more favorable to the holders of Company common stock than potential alternatives to the Company Merger, which belief was formed based on the board of directors' review, with the assistance of management and the Company's advisors, of potential strategic alternatives available to the Company, including continued operation as an independent company (with or without the Erdman business);
•: the fact that the all-cash per share merger consideration will provide holders of Company common stock with immediate fair value, in cash, for their shares, while avoiding long-term business risk, and while also providing holders of Company common stock with certainty of value for their shares;
•: the fact that the per share merger consideration represents a premium of approximately 11.3% to the average closing share price of Company common stock for the 30-day trading period ended on December 23, 2011, the last trading day prior to the public announcement of the merger agreement, and a premium of approximately 8.4% to the closing share price of Company common stock on December 23, 2011;
•: the board of directors' belief that, in light of the solicitation process conducted at the direction of, and in consultation with, our board of directors and the board of directors' knowledge of other participants in the REIT industry, another party would be unlikely to propose an alternative transaction that would be more favorable to the Company and the holders of Company common stock than the Company Merger, and the fact that, if such alternative

Table of Contents

transaction were proposed, it could be pursued subject to the terms of the merger agreement as described below;

•

Citi's opinion and financial presentation, dated December 23, 2011, to the Company's board of directors as to the fairness, from a financial point of view and as of the date of the opinion, of the $4.25 per share merger consideration to be received in the Company Merger by holders of Company common stock, as more fully described below under the caption "Opinion of the Company's Financial Advisor";

•

the likelihood that the Company Merger would be completed based on, among other things (not in any relative order of importance):

•: the reputation of Ventas, its familiarity with the Company's industry and its demonstrated ability to complete similar acquisition transactions;
•: the fact that there is no financing or due diligence condition to the completion of the Company Merger in the merger agreement;
•: the board's assessment of Ventas's resources and access to capital markets to fund the consideration contemplated by the merger agreement;
•: the fact that the merger agreement provides that, in the event of a failure of the Company Merger to be consummated under certain circumstances where the conditions to consummation of the Company Merger have been satisfied, Ventas will pay the Company a $15.0 million termination fee, without the Company having to establish any damages, as well as expense reimbursement of $5.0 million;

•

the Company's ability, under certain circumstances specified in and prior to the time the holders of Company common stock approve the Company Merger, to (i) provide non-public information in response to an unsolicited written acquisition proposal and (ii) participate in discussions or negotiations with the person making such a proposal, if, in each case, the acquisition proposal was not the result of a violation of the provisions of the merger agreement relating to the solicitation of acquisition proposals, and if the board of directors, prior to taking any such actions, determines in good faith, after consultation with its outside legal counsel, that failure to take such actions would be reasonably likely to lead to a breach of the duties of the Company's directors under applicable law and, after consultation with the Company's outside counsel and financial advisor, that such acquisition proposal either constitutes a superior proposal or is reasonably likely to lead to a superior proposal;

the board of directors' ability, under certain circumstances, to (i) withhold, withdraw, qualify or modify the Company recommendation or (ii) cause the Company to terminate the merger agreement in order to enter into an agreement providing for a superior proposal, subject in each case to the payment by the Company of a termination fee of $15.0 million to Ventas plus expense reimbursement of $5.0 million, which the board of directors concluded was reasonable in the context of termination fees in comparable transactions and in light of the overall terms of the merger agreement, including the per share merger consideration;

•

the fact that the outside date under the merger agreement allows for sufficient time to complete the Company Merger;

•

the board of directors' review of the potential costs associated with entering into the merger agreement and consummating the Company Merger, including change in control severance and related costs, some or all of which will be discharged by the Company without reducing the per share consideration to be received by the stockholders;

Table of Contents

•: that no other bidder proposed a cash price in a final bid that was as high as the per share merger consideration offered by Ventas;
•: the fact that Ventas's obligation to complete the transaction is not subject to any condition that the Company obtain consents to the assumption of certain of its property-level indebtedness by the surviving company; and
•: the fact that the Erdman purchase agreement provides the Company the opportunity to actively market the Erdman business for superior proposals, subject to the requirement that the Company pay a termination fee of $400,000 to the initial Erdman purchaser, which the Company expects would be funded from the incremental proceeds.

The board of directors also considered a variety of potentially negative factors in its deliberations concerning the merger agreement and the Company Merger, including the following (not in any relative order of importance):

•: the Company Merger would preclude the holders of Company common stock from having the opportunity to participate in the future performance of the Company's assets, future earnings growth and future appreciation of the value of Company common stock;
•: the fact that an all-cash transaction would be taxable to the Company's stockholders that are U.S. holders for U.S. federal income tax purposes;
•: the significant costs involved in connection with entering into and completing the Company Merger and the substantial time and effort of management required to complete the Company Merger and related disruptions to the operation of the Company's business;
•: the fact that the $4.25 per share merger consideration implies a lower premium or a discount for the Company relative to the premiums paid for many other companies acquired in the industry;
•: the announcement and pendency of the Company Merger, or failure to complete the Company Merger, may cause substantial harm to relationships with the Company's employees, vendors and customers and may divert management and employee attention away from the day-to-day operation of our business;
•: the restrictions on the conduct of the Company's business prior to the completion of the Company Merger, which, subject to specific exceptions, could delay or prevent the Company from undertaking business opportunities that may arise or any other action it would otherwise take with respect to the operations of the Company absent the pending completion of the Company Merger;
•: the fact that the Company would be prohibited from affirmatively soliciting acquisition proposals for the Company after execution of the merger agreement;
•: the possibility that the $15.0 million termination fee and $5.0 million expense reimbursement payable by the Company upon the termination of the merger agreement under certain circumstances could discourage other potential acquirers from making a competing bid to acquire the Company;
•: the fact that, while the Company expects that the Company Merger will be consummated, there can be no assurance that all conditions to the parties' obligations to complete the Company Merger set forth in the merger agreement will be satisfied, and, as a result, the Company Merger may not be consummated;
•: that the requirement of the bidders that the Company dispose of the Erdman business as a condition to consummating the Company Merger effectively limited the ability of the Company

Table of Contents

to broadly market the Erdman business on a standalone basis prior to execution of the merger agreement; and

•: the fact that the Company's directors and executive officers have interests in the Company Merger and the Partnership Merger that are different from, or in addition to, the interests of the holders of Company common stock. See "The Company Merger—Interests of the Company's Directors and Executive Officers in the Company Merger" beginning on page 50.

The foregoing discussion of the information and factors considered by the board of directors is not intended to be exhaustive, but includes the material factors considered by the board of directors in evaluating the Company Merger. In view of the variety of factors considered in connection with its evaluation of the Company Merger, the board of directors did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific factors considered in reaching its determination and recommendation. In addition, individual directors may have given different weights to different factors. The board of directors did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determination. The board of directors based its recommendation on the totality of the information presented.

In considering the recommendation of the board of directors with respect to the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, you should be aware that some of our directors and executive officers have interests in the Company Merger that are different from, or in addition to, yours. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the Company Merger, and in recommending that the Company Merger be approved by the stockholders of the Company. See "The Company Merger—Interests of the Company's Directors and Executive Officers in the Company Merger" beginning on page 50.

Opinion of the Company's Financial Advisor

The Company has retained Citi as its financial advisor in connection with the Mergers. In connection with this engagement, the Company requested that Citi evaluate the fairness, from a financial point of view, of the $4.25 per share merger consideration to be received in the Company Merger by holders of Company common stock. On December 23, 2011, at a meeting of the Company's board of directors at which the Company Merger was approved, Citi rendered to the board an oral opinion, confirmed by delivery of a written opinion dated December 23, 2011, to the effect that, as of that date and based on and subject to the matters described in its opinion, the $4.25 per share merger consideration to be received in the Company Merger by holders of Company common stock was fair, from a financial point of view, to such holders. For purposes of this section, the term "Cogdell Spencer" refers to the Company, together with OP.

The full text of Citi's written opinion, dated December 23, 2011, which describes the assumptions made, procedures followed, matters considered and limitations on the review undertaken, is attached to this proxy statement asAnnex B and is incorporated into this proxy statement by reference. The description of Citi's opinion set forth in this proxy statement is qualified in its entirety by reference to the full text of Citi's opinion.Citi's opinion was provided for the information of the Company's board of directors (in its capacity as such) in connection with its evaluation of the Company Merger and only addressed the fairness, from a financial point of view, of the $4.25 per share merger consideration

Table of Contents

to be received by holders of Company common stock in the Company Merger. Citi's opinion did not address any other aspects or implications of the Mergers or any related transaction. Citi was not requested to consider, and its opinion did not address, the underlying business decision of the Company to effect the Mergers or any related transaction, the relative merits of the Mergers or any related transaction as compared to any alternative business strategies that might exist for Cogdell Spencer or the effect of any other transaction in which Cogdell Spencer might engage. Citi's opinion is not intended to be and does not constitute a recommendation to any security holder as to how such security holder should vote or act on any matters relating to the proposed Mergers, any related transaction or otherwise.

In arriving at its opinion, Citi:

•: reviewed a draft dated December 22, 2011 of the merger agreement;
•: held discussions with certain senior officers, directors and other representatives and advisors of Cogdell Spencer concerning the business, operations and prospects of Cogdell Spencer;
•: reviewed certain publicly available business and financial information relating to Cogdell Spencer;
•: reviewed certain financial forecasts and other information and data relating to Cogdell Spencer provided to or discussed with Citi by Cogdell Spencer's management;
•: reviewed the financial terms of the Mergers as set forth in the merger agreement in relation to, among other things, current and historical market prices of Company common stock, Cogdell Spencer's historical and projected earnings and other operating data, and Cogdell Spencer's capitalization and financial condition, including the liquidity requirements of, and capital resources available to, Cogdell Spencer;
•: analyzed certain financial, stock market and other publicly available information relating to the businesses of other companies whose operations Citi considered relevant in evaluating those of Cogdell Spencer;
•: analyzed, to the extent publicly available, the financial terms of certain other transactions which Citi considered relevant in evaluating the Mergers; and
•: conducted such other analyses and examinations and considered such other information and financial, economic and market criteria as Citi deemed appropriate in arriving at its opinion.

In rendering its opinion, Citi assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with Citi and upon the assurances of Cogdell Spencer's management that it was not aware of any relevant information that was omitted or remained undisclosed to Citi. With respect to the financial forecasts and other information and data provided to or otherwise reviewed by or discussed with Citi relating to Cogdell Spencer, Citi was advised by Cogdell Spencer's management, and Citi assumed, with the Company's consent, that such forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of Cogdell Spencer's management as to the future financial performance of Cogdell Spencer.

Citi did not make, and it was not provided with, an independent evaluation or appraisal of the assets or liabilities, contingent or otherwise, of Cogdell Spencer, and Citi did not make any physical inspection of the properties or assets of Cogdell Spencer. Citi is not a real estate appraiser and expressed no opinion as to the value of any individual property of Cogdell Spencer, or the price at which any such property might be transferable, at any time. Citi was advised by Cogdell Spencer's management, and Citi assumed, with the Company's consent, that the Company has operated in

Table of Contents

conformity with the requirements for qualification as a REIT for federal income tax purposes since its formation as a REIT. Citi assumed, with the Company's consent, that the Mergers and related transactions (including the Erdman Sale and any related cash dividend) would be consummated in accordance with their respective terms without waiver, modification or amendment of any material term, condition or agreement and in compliance with all applicable laws and other requirements and that, in the course of obtaining the necessary regulatory or third party approvals, consents, releases and waivers for the Mergers or related transactions, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Cogdell Spencer or the Mergers that would be material to Citi's analyses or opinion. Representatives of Cogdell Spencer advised Citi, and Citi also assumed, that the final terms of the merger agreement would not vary materially from those set forth in the draft reviewed by Citi or as otherwise described to Citi. In connection with Citi's engagement and at the Company's direction, Citi was requested to approach, and Citi held discussions with, third parties to solicit indications of interest in the possible acquisition of Cogdell Spencer.

Citi's opinion did not address any terms (other than the $4.25 per share merger consideration to be received in the Company Merger by holders of Company common stock to the extent expressly specified in Citi's opinion) or other aspects or implications of the Mergers, the Erdman Sale or any other related transaction, including, without limitation, the form or structure of the Mergers or any related transaction, the consideration payable in or any tax or other consequences of the Erdman Sale, the consideration payable in respect of any other securities of Cogdell Spencer or any other agreement, arrangement or understanding to be entered into in connection with or contemplated by the Mergers, any related transaction or otherwise. Citi expressed no view as to, and its opinion did not address, the fairness (financial or otherwise) of the amount or nature or any other aspect of any compensation to any officers, directors or employees of any parties to the Mergers, or any class of such persons, relative to the $4.25 per share merger consideration or otherwise. Citi did not express any opinion as to the solvency or fair value of Cogdell Spencer or any part thereof or the prices at which Company common stock would trade at any time. In addition, Citi expressed no view or opinion as to, and relied, without independent verification and with the Company's consent, upon the assessments of representatives of Cogdell Spencer regarding, legal, regulatory, accounting, tax or similar matters relating to Cogdell Spencer, the Mergers and related transactions as to which Citi understood that Cogdell Spencer had obtained such advice as Cogdell Spencer deemed necessary from qualified professionals. Citi's opinion was necessarily based on information available to Citi, and financial, stock market and other conditions and circumstances existing and disclosed to Citi, as of the date of its opinion. The credit, financial and stock markets have been experiencing unusual volatility and Citi expressed no opinion or view as to any potential effects of such volatility on Cogdell Spencer or the Mergers. Except as described in this summary, the Company imposed no other instructions or limitations on Citi with respect to the investigations made or procedures followed by Citi in rendering its opinion.

In preparing its opinion, Citi performed a variety of financial and comparative analyses, including those described below. This summary of the analyses is not a complete description of Citi's opinion or the analyses underlying, and factors considered in connection with, Citi's opinion. The preparation of a financial opinion is a complex analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to summary description. Citi arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole, and did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis for purposes of its opinion. Accordingly, Citi believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion.

Table of Contents

In its analyses, Citi considered industry performance, general business, economic, market and financial conditions and other matters existing as of the date of its opinion, many of which are beyond the control of Cogdell Spencer. No company, business or transaction reviewed is identical to Cogdell Spencer or the Mergers. An evaluation of these analyses is not entirely mathematical; rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the public trading or other values of the companies, business segments or transactions reviewed.

The estimates contained in Citi's analyses and the valuation ranges resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by its analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold or acquired. Accordingly, the estimates used in, and the results derived from, Citi's analyses are inherently subject to substantial uncertainty.

Citi was not requested to, and it did not, recommend the specific consideration payable in the Mergers. The type and amount of consideration payable in the Mergers was determined through negotiations between the Company and Ventas and the decision to enter into the merger agreement was solely that of the Company's board of directors. Citi's opinion was only one of many factors considered by the Company's board of directors in its evaluation of the Mergers and should not be viewed as determinative of the views of the Company's board of directors or management with respect to the Mergers or the consideration to be received in the Company Merger.

The following is a summary of the material financial analyses provided to the Company's board of directors in connection with Citi's opinion.The financial analyses summarized below include information presented in tabular format. In order to fully understand Citi's financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Citi's financial analyses.

Selected Public Companies Analysis. Citi reviewed financial and stock market information of Cogdell Spencer and the following four selected publicly traded healthcare REITs with medical office building portfolios:

•: HCP, Inc.
•: Health Care REIT, Inc.
•: Healthcare Realty Trust Incorporated
•: Ventas

Citi reviewed, among other things, closing stock prices of the selected companies on December 22, 2011 as a multiple of calendar year 2012 estimated funds from operations, or FFO, per share. Citi then applied a range of selected multiples of calendar year 2012 estimated FFO per share of 14.0x to 15.0x derived from the selected companies to corresponding data of Cogdell Spencer. Financial data of the selected companies were based on publicly available research analysts' estimates, public filings and other publicly available information. Financial data of Cogdell Spencer were based on internal estimates of Cogdell Spencer's management. This analysis indicated the following approximate implied per share equity value reference range for Cogdell Spencer, as compared to the $4.25 per share merger consideration to be received in the Company Merger:

	Implied Per Share Equity Value Reference Range		Company Merger Consideration

	$3.92 - $4.20		$4.25

Selected Precedent Transactions—Premiums Paid Analysis. Citi reviewed publicly available data relating to 99 transactions involving REITs announced between January 1, 2000 and December 22, 2011, as reported in SNL Financial as of December 22, 2011. Citi reviewed the implied premiums paid in the selected transactions relative to the estimated net asset values of the target companies in such transactions. Citi also reviewed the implied premiums paid in the selected transactions relative to the average closing stock prices of the target companies in such transactions during the one-month and three-month periods prior to public announcement of the relevant transaction. Citi then applied a range of implied premiums paid derived from the selected transactions, based on estimated net asset values to the extent publicly available, of (21.4)% to 93.5% to an illustrative net asset value of $4.64 per share of Company common stock (derived based on a net asset value analysis of Cogdell Spencer as more fully described below under the caption "Net Asset Value Analysis" utilizing a nominal capitalization rate of 7.5%). Citi also applied ranges of implied premiums paid derived from the selected transactions, based on one-month and three-month average closing stock prices, of (12.0)% to 82.5% and (13.9)% to 66.7%, respectively, to the average closing prices of Company common stock during the one-month and three-month periods ended December 22, 2011. Financial data relating to the selected transactions were based on publicly available information. Financial data of Cogdell Spencer were based on internal estimates of Cogdell Spencer's management. This analysis indicated the following approximate implied per share equity value reference ranges for Cogdell Spencer, as compared to the $4.25 per share merger consideration to be received in the Company Merger:

Implied Per Share Equity Value Reference Range Based on Implied Premiums Paid Relative to:

Estimated Net Asset Value	One-Month Average Closing Stock Price	Three-Month Average Closing Stock Price	Company Merger Consideration
$3.65 - $8.98	$3.30 - $6.83	$3.27 - $6.32	$	4.25

Net Asset Valuation Analysis. Citi performed a net asset valuation analysis of Cogdell Spencer based on the estimated aggregate value of Cogdell Spencer's income-producing properties and other assets, including the Erdman business. Citi calculated the estimated value of Cogdell Spencer's income-producing properties by applying a range of selected nominal capitalization rates (derived from publicly available information relating to selected transactions involving medical office buildings with announced transaction values in excess of $50 million between January 1, 2008 and December 22, 2011) of 7.0% to 7.75% to Cogdell Spencer's calendar year 2012 estimated stabilized cash net operating income for such properties. Citi also calculated the estimated value of Cogdell Spencer's income-producing properties by applying ranges of selected nominal capitalization rates and selected economic capitalization rates (in each case, derived from publicly available financial information relating to the selected companies referred to above under the caption "Selected Public Companies Analysis") of 6.15% to 7.71% and 5.83% to 6.88%, respectively, to Cogdell Spencer's calendar year 2012 estimated stabilized cash net operating income and estimated stabilized cash net operating income, less estimated run-rate capital expenditures, referred to as stabilized economic cash net operating income, for such properties. Estimated financial data for Cogdell Spencer's income-producing properties were based on internal estimates of Cogdell Spencer's management. Other asset values were calculated as follows:

•: in the case of the Erdman business, based on a discounted cash flow analysis in which Citi calculated the estimated present value (as of January 1, 2012), utilizing discount rates ranging from 10.0% to 16.0%, of (a) the unlevered, after-tax free cash flows that the Erdman business was forecasted to generate on a standalone basis from third-party projects from calendar year 2012 through calendar year 2016 based on internal estimates of Cogdell Spencer's management both before and after giving effect to a sensitivity for reduced selling, general and administrative expenses per Cogdell Spencer's management and (b) terminal values for the Erdman business derived by applying a range of terminal value multiples of 4.0x to 6.0x to Cogdell Spencer's calendar year 2017 estimated earnings before interest, taxes, depreciation and amortization for

Table of Contents

the Erdman business on a standalone basis from third-party projects based on internal estimates of Cogdell Spencer's management; and

•: in the case of development properties and other assets and liabilities, based on book values of such assets.

This analysis indicated the following approximate implied per share equity value reference ranges for Cogdell Spencer, as compared to the $4.25 per share merger consideration to be received in the Company Merger:

Implied Per Share Equity Value Reference Range Based on:

Selected Transactions Nominal Capitalization Rates	Selected Companies Nominal Capitalization Rates	Selected Companies Economic Capitalization Rates	Company Merger Consideration
$4.12 - $6.18	$4.18 - $8.09	$2.35 - $5.00	$	4.25

Other Information. Citi also noted for the Company's board of directors certain additional factors that were not considered part of Citi's financial analysis with respect to its opinion but were referenced for informational purposes, including, among other things, daily closing trading prices of Company common stock during the 52-week period ended December 22, 2011, noting that during such period these trading prices ranged from $3.44 to $6.71 per share.

Miscellaneous

Under the terms of Citi's engagement, the Company has agreed to pay Citi for its financial advisory services in connection with the Mergers an aggregate fee currently estimated to be approximately $6.1 million, a portion of which was payable upon delivery of Citi's opinion and approximately $5.5 million of which is contingent upon completion of the Mergers. At the Company's discretion, Citi also may receive an additional fee currently estimated to be approximately $2.9 million upon completion of the Mergers. The Company also has agreed to reimburse Citi for reasonable expenses incurred by Citi in performing its services, including reasonable fees and expenses of its legal counsel, and to indemnify Citi and related persons against liabilities, including liabilities under the federal securities laws, arising out of its engagement. Citi and its affiliates in the past have provided, currently are providing and in the future may provide investment banking and other financial services to Cogdell Spencer and Ventas unrelated to the proposed Mergers, for which services Citi and its affiliates have received and expect to receive compensation, including, during the two-year period prior to the date of Citi's opinion, aggregate fees of approximately $1.5 million from Cogdell Spencer and approximately $3.3 million from Ventas, as the case may be, for acting as (i) joint lead arranger and co-documentation agent for, and/or a lender under, $200 million and $80.8 million credit facilities of Cogdell Spencer and a $2 billion unsecured revolving credit facility of Ventas, (ii) joint bookrunner and administrative agent for, and a lender under, a $500 million unsecured term loan of Ventas, (iii) joint book-running manager for a $73.5 million preferred stock offering of the Company in 2010, a $49.9 million common stock offering of the Company in 2010 and a $700 million and $400 million notes offering of Ventas in 2011 and 2010, respectively, and (iv) co-sales agent for a $40 million equity distribution program by the Company commenced in 2010. In addition, Citi acted as sole underwriter for a $1.13 billion secondary offering by selling stockholders of Ventas common stock in January 2012.

In the ordinary course of business, Citi and its affiliates may actively trade or hold the securities of the Company and Ventas for their own account or for the account of their customers and, accordingly, may at any time hold a long or short position in those securities. Citi and its affiliates, including Citigroup Inc. and its affiliates, may maintain relationships with Cogdell Spencer, Ventas and their respective affiliates.

The Company selected Citi as its financial advisor in connection with the merger based on Citi's reputation and experience and familiarity with Cogdell Spencer and its business. Citi is an

Table of Contents

internationally recognized investment banking firm which regularly engages in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. The issuance of Citi's opinion was authorized by Citi's fairness opinion committee.

Certain Company Forecasts

While the Company provides public guidance for the current fiscal year, and periodically updates such guidance during the course of the fiscal year, it does not, as a matter of course, publicly disclose financial forecasts or internal projections as to future financial performance, earnings or other results for periods longer than one year. The Company is especially cautious of making financial forecasts for periods longer than one fiscal year due to the inherent unpredictability of underlying assumptions and estimates. However, in connection with the evaluation of a possible transaction involving the Company, certain prospective financial information, which we refer to as the financial forecasts, was prepared by our management and reviewed with and discussed with members of the board of directors and the Company's financial advisor, portions of which also were provided to Ventas (and other interested bidders) and their advisors to facilitate their due diligence review. These financial forecasts were not prepared with a view toward public disclosure, are not intended to be an update to previously issued external guidance issued by the Company, and may differ from publicized analyst estimates and forecasts. Management's key assumptions supporting the financial forecasts are discussed below.

We have included the material portions of the financial forecasts below. This information is not included in this document to influence your decision whether to vote for or against the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, but is being included because these financial forecasts were made available to the board of directors, Ventas (and other interested bidders) and their respective advisors. The inclusion of this information should not be regarded as an indication that the Company's board of directors or advisors or any other person considered, or now considers, such financial forecasts to be material or necessarily predictive of actual future results, and these forecasts should not be relied upon as such. Our management's internal financial forecasts, upon which the financial forecasts were based, are subjective in many respects. There can be no assurance that these financial forecasts will be realized or that actual results will not be significantly higher or lower than forecasted. The financial forecasts cover multiple years and such information by its nature becomes subject to greater uncertainty with each successive year. As a result, the inclusion of the financial forecasts in this proxy statement should not be relied on as necessarily predictive of actual future events.

The financial forecasts are not intended to comply with generally accepted accounting principles, or GAAP, the published guidelines of the SEC regarding projections and the use of non-GAAP measures or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. Some of the financial forecasts present financial metrics that were not prepared in accordance with GAAP. Neither our independent registered public accounting firm, nor any other independent accountants, have compiled, examined or performed any procedures with respect to the financial forecasts contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and they assume no responsibility for, and disclaim any association with, the prospective financial information.

These financial forecasts are forward-looking statements and were based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of the Company. Important factors that may affect actual results and cause these financial forecasts not to be achieved include, but are not limited to, risks and uncertainties relating to industry performance, competition, the regulatory environment, changes in general business, economic, or geopolitical conditions, and currency, market and financial conditions, as well as changes to the business, financial condition or

Table of Contents

results of operation of the Company, including the factors described or referenced under "Cautionary Statement Concerning Forward-Looking Information" beginning on page 19 and other risk factors described in our filings with the SEC that could cause actual results to differ materially from those shown below. In addition, the forecasts reflect assumptions that are difficult to predict and subject to change and may not reflect current prospects for the Company's business, changes in general business or economic conditions, or any other transaction or event that has occurred or that may occur and that was not anticipated at the time the financial forecasts were prepared. In addition, the projections do not take into account any of the transactions contemplated by the merger agreement, including the Company Merger, which might also cause actual results to differ materially. Accordingly, there can be no assurance that these financial forecasts will be realized or that the Company's future financial results will not materially vary from these financial forecasts.

We have made publicly available our actual results for the first three quarters of the 2011 fiscal year ended March 31, 2011, June 30, 2011 and September 30, 2011. You should review our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2011, June 30, 2011 and September 30, 2011, respectively, to obtain this information. See "Where You Can Find More Information" beginning on page 89.

No one has made or makes any representation to readers of this proxy statement regarding the information included in the financial forecasts set forth below. Readers of this proxy statement are cautioned not to rely unduly on the forecasted financial information. Some or all of the assumptions which have been made regarding, among other things, the timing of certain occurrences or impacts, may have changed since the date such forecasts were made. We have not updated and do not intend to update, or otherwise revise the financial forecasts to reflect circumstances existing after the date when made or to reflect the occurrence of future events, even in the event that any or all of the assumptions on which such forecasts were based are shown to be in error. The Company has made no representation to Ventas or MergerSub in the merger agreement or otherwise concerning these financial forecasts.

In preparing the summary financial forecasts, our management made the following key assumptions:

•

GAAP Net Operating Income:

•: In-place rent increases based on projected Consumer Price Index (CPI) growth;
•: Lease-up and lease renewal assumptions based on management estimates;
•: No property acquisitions or dispositions;
•: New development spending of $26 million in 2012 for Good Sam MOB in Puyallup, Washington and St. Luke's MOB in Duluth, Minnesota;
•: New development spending of $83 million in 2013 and $95 million in 2014;
•: New development spending in 2013 and 2014 assumed to generate an 8.0% unleveraged cash yield upon stabilization; and
•: No new incremental joint venture projects.

•

Design-build:

•: Projected revenue based on existing prospect pipeline;
•: 2012: 56% of revenues related to on-balance sheet projects; 44% related to third-party projects;
•: 2013 and 2014: 50% of revenues related to on-balance sheet projects; 50% related to third-party projects; and

Table of Contents

•: Total selling, general and administrative expenses increase by 6.8% in 2012, 8.3% in 2013 and 2.4% in 2014.

•

Third party property management:

•: Projected annual revenue of $3.2 million; and
•: Projected annual expenses of $2.7 million; and

•

Corporate general and administrative expenses increase by $500,000 per year.

The following consolidated corporate financial forecasts and projections were prepared by management of the Company and given to Ventas (and other interested bidders), the board of directors and their respective advisors. These forecasts and projections were based on the Company as a whole and did not reflect the sale of the Erdman business separately.

Management of the Company also prepared a projection for calendar year 2012 estimated FFO per share of $0.28, which was provided to the Company's board of directors and financial advisor and not to any bidder for the Company.

The following forecasts and projections, which provide greater detail regarding the calculation of projected EBITDA for the Erdman business, were provided to Ventas (and other interested bidders), the board and their respective advisors. Although designed to show projected performance of the Erdman business, these projections assumed operation of the Erdman business as part of the overall Company. The performance of the Erdman business on a standalone basis would likely differ materially from the projections set forth below. For example, as noted above, these projections are based on assumptions that at least 50% of design-build projects would be on-balance sheet and therefore funded by the Company. Without access to such development capital, either because Erdman is operated as a standalone business or because the Company is not able to provide such capital, it is likely that the performance of the Erdman business would differ materially from these projections.

Management also prepared the following forecasts and projections for the Erdman business, assuming that no further funding from the Company would be available for on-balance sheet projects and all future design-build projects would be owned and funded by third parties.

Financing of the Mergers

Ventas has represented and warranted to the Company that, on the closing date, Ventas, MergerSub and OP MergerSub will have sufficient funds to satisfy all of the obligations of Ventas, MergerSub and OP MergerSub under the merger agreement, including (i) the payment of any amounts required to be paid as consideration to the holders of Company common stock, the Company's Series A Preferred Stock, partnership interests in the Operating Partnership, restricted Company common stock and long-term incentive plan units of limited partnership interest in the Operating Partnership, (ii) the payment of any indebtedness of the Company and the Company's subsidiaries required to be repaid, redeemed, retired, cancelled or terminated or otherwise satisfied in connection with or as a result of the Mergers, and (iii) the payment of all fees and expenses reasonably expected to be incurred by Ventas and MergerSub in connection therewith.

Closing and Effective Time of Mergers

Unless the parties otherwise agree in writing, the closing of the Mergers will take place at (x) 10:00 a.m. local time on the third business day following the date on which the last of the conditions to closing of the Mergers (described under "The Merger Agreement—Conditions to the Mergers" beginning on page 76) has been satisfied or waived (other than those conditions that by their nature are to be satisfied at the closing of the Mergers, but subject to the satisfaction or waiver of those conditions) or (y) at such other time as Ventas and the Company may agree; provided, that, notwithstanding the foregoing, Ventas, in its sole discretion, has the right to extend the closing of the Mergers (i) for up to 45 days for any reason and (ii) for up to an additional 30 days for the purpose of obtaining any consent, amendment or waiver from any lenders of the Company and/or the Company's subsidiaries with respect to any indebtedness of the Company and the Company's subsidiaries, any counterparties to joint venture or partnership agreements, and/or any lessors under ground leases, but Ventas may not extend the closing for such purposes to any date after May 15, 2012. Assuming timely satisfaction of the necessary closing conditions, we anticipate that the Mergers will be completed during the second quarter of 2012.

Payment of Merger Consideration and Surrender of Stock Certificates

In connection with the Company Merger, each record holder of shares of Company common stock, shares of Series A Preferred Stock, and OP Units will be sent a letter of transmittal, not later than the fifth business day following completion of the Mergers, describing how such holder may exchange its shares of Company common stock, Series A Preferred Stock or OP Units, as applicable, for the appropriate consideration.

You should not return your stock certificates with the enclosed proxy card, and you should not forward your stock certificates to the paying agent without a letter of transmittal.

Table of Contents

You will not be entitled to receive the per share merger consideration or preferred per share merger consideration, as applicable, until you deliver a duly completed and executed letter of transmittal to the paying agent. If ownership of your shares is not registered in the transfer records of the Company because a transfer has occurred, the per share merger consideration or preferred per share merger consideration, as applicable, will be paid if the applicable letter of transmittal is accompanied by the stock certificates representing such shares, all documents and endorsements required to evidence and effect such transfer, and evidence that any applicable stock transfer taxes have been paid.

Interests of the Company's Directors and Executive Officers in the Company Merger

When considering the recommendation of the board of directors that you vote to approve the proposal to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, you should be aware that some of our directors and executive officers have interests in the Company Merger that are different from, or in addition to, the interests of our stockholders generally. These interests may present them with actual or potential conflicts of interest, and these interests, to the extent material, are described below. The board of directors was aware of and considered these interests, among other matters, in evaluating and negotiating the merger agreement and the Company Merger, and in recommending that the Company Merger be approved by the stockholders of the Company. In the discussion below, we have quantified the potential payments and benefits to our executive officers and to our non-employee directors in connection with the Company Merger. For the purposes of all of the agreements and plans described below, the completion of the transactions contemplated by the merger agreement will constitute a change in control and a sale of the Company.

Equity Compensation Awards

Effective immediately before the effective time of the Company Merger, each outstanding share of restricted stock granted under the Company's equity plans will become fully vested and will convert into the right to receive the per share merger consideration, in each case without interest and less any applicable withholding taxes.

The following table sets forth for each person who has been an executive officer or non-employee director of the Company at any time since the beginning of our most recent completed fiscal year, (i) the number and value of outstanding vested LTIP Units expected to convert in connection with the Partnership Merger into an OP Unit, which generally will entitle the holder to receive the per share merger consideration, (ii) the number and value of outstanding unvested LTIP Units which will become fully vested and are expected to convert in connection with the Partnership Merger into an OP Unit, which generally will entitle the holder to receive the per share merger consideration, (iii) the number and value of shares of restricted stock which will become fully vested and entitle the holder to receive the per share merger consideration, and (iv) the value and number of OP Units which will convert into

(1): Calculated by assuming such LTIP Units convert into OP units on a 1-for-1 basis, and multiplying the resulting number of OP Units by the per share merger consideration of $4.25.

Employment Agreements with Messrs. Braun and Handy

We previously entered into employment agreements with each of Messrs. Braun and Handy, which provide for the payment of certain severance benefits if the executive is involuntarily terminated without "cause" or, in the case of Mr. Handy, if the executive terminates his employment with "good reason" (as such terms are defined below). In addition, if Mr. Handy terminates his employment with us within one year following a change in control, such as the Company Merger, for any reason, such termination shall be deemed a termination by him for good reason.

Upon a termination of Mr. Braun's employment by us without cause, Mr. Braun will be entitled to receive the following severance payments and benefits: (i) a lump-sum cash payment equal to his current annual base salary; (ii) a pro-rata (based on the number of days employed in the fiscal year of termination) maximum annual bonus for the fiscal year in which his termination occurs; and (iii) continuing coverage at active employee rates under our group health plans for one year after termination of employment. In addition, upon a change in control, Mr. Braun's outstanding restricted shares become fully-vested and non-forfeitable.

Upon a termination of Mr. Handy's employment either (i) by us without cause, (ii) by him for good reason, or (iii) by him for any reason within one year following a change in control, Mr. Handy will be entitled to receive the following severance payments and benefits: (i) a lump-sum cash payment equal to 1.99 multiplied by the sum of (1) his then-current annual base salary and (2) the greater of (A) the average bonus paid to him over the previous two years, and (B) the maximum bonus payable to him for the fiscal year in which the termination occurs (such sum, the "Base Severance Amount"); and (ii) continuing coverage at active employee rates under our group health plans for three years after termination of employment. In addition, upon a change in control, Mr. Handy's outstanding unvested LTIP Units become fully vested.

Table of Contents

In the event we give Mr. Handy notice of non-renewal of his employment agreement, Mr. Handy will be entitled to the same payments and benefits as if terminated by us without cause, except that his lump-sum cash payment will equal the Base Severance Amount. In addition, if we elect to subject Mr. Handy to the non-competition and non-solicitation provisions described below, he will be entitled to a cash payment equal to the Base Severance Amount.

In the event that any amount payable to Mr. Handy is determined to be an "excess parachute payment" under Section 280G of the Internal Revenue Code of 1986, as amended, which we refer to as the Code, he will be entitled to a gross-up payment equal to the excise tax imposed under Section 4999 of the Code. The amount of gross-up payment (which is also treated as an excess parachute payment) will be equal to the sum of the excise taxes payable by Mr. Handy by reason of receiving the parachute payments plus the amount necessary to put Mr. Handy in the same after-tax position as if no excise taxes had been imposed on Mr. Handy (taking into account any and all applicable federal, state and local excise, income or other taxes at the highest applicable rates).

For purposes of the employment agreements with Messrs. Braun and Handy, "cause" generally means: (i) conviction of, or formal admission to, a felony, including, for Mr. Handy, conviction of, or formal admission to, a misdemeanor the circumstances of which are to the material detriment to the Company's reputation whether or not in the performance of duties thereunder; (ii) engagement in the performance of his duties, or otherwise to our material and demonstrable detriment, in willful misconduct, willful or gross neglect, fraud, misappropriation or embezzlement; (iii) repeated failure to adhere to the directions of our Board, or to adhere to our policies and practices; (iv) willful and continued failure to substantially perform the executive's duties properly assigned to him (other than any such failure resulting from his disability) after demand for substantial performance is delivered by us specifically identifying the manner in which we believe he has not substantially performed such duties; (v) breach of any of the provisions of the covenants of his employment agreement; or (vi) breach in any material respect of the terms and provisions of his employment agreement and failure to cure such breach within 30 days following written notice from us specifying such breach.

For purposes of the employment agreement with Mr. Handy, "good reason" generally means: (i) the material reduction of his authority, duties and responsibilities, the failure to continue Mr. Handy's appointment in his given position, or the assignment to him of duties materially inconsistent with his position or positions with us; (ii) a reduction in Mr. Handy's annual salary; (iii) the relocation of Mr. Handy's office to more than 50 miles from Charlotte, North Carolina; or (iv) our material and willful breach of Mr. Handy's employment agreement.

The term "change of control" as used in the employment agreements with Messrs. Braun and Handy is generally defined to mean: (i) any transaction by which any person or group becomes the beneficial owner, either directly or indirectly, of our securities representing 50% or more of either (1) the combined voting power of our then outstanding securities or (2) the then outstanding shares of our Common Stock; or (ii) any consolidation or merger where our stockholders, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own, directly or indirectly, shares representing in the aggregate 50% or more of the combined voting power of the securities of the corporation issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any); or (iii) there shall occur (1) any sale, lease, exchange or other transfer of all or substantially all of our assets, or (2) the approval by our stockholders of any plan or proposal for our liquidation or dissolution; or (iv) the members of our Board, at the beginning of any consecutive 24-calendar-month period cease for any reason other than due to death to constitute at least a majority of the members of the Board.

Table of Contents

Pursuant to the terms of the non-competition provisions in Messrs. Braun and Handy's employment agreements, the executive officer is generally prohibited for a one-year period, in the case of Mr. Braun, and for a two-year period, in the case of Mr. Handy, following termination from, directly or indirectly, whether as an owner, partner, stockholder, principal, agent, employee, consultant or in any other relationship or capacity, engaging in any element of our business or otherwise competing with us or our affiliates, rendering any services to any person, corporation, partnership or other entity engaged in competition with us or our affiliates, or providing financial assistance to or otherwise obtaining an ownership interest in a competitor of ours or of our affiliates within a restricted territory encompassing several states in the southeast. The executive officer is generally prohibited, for a one-year period, in the case of Mr. Braun, and for a two-year period, in the case of Mr. Handy, from, directly or indirectly, knowingly soliciting or encouraging to leave the employment or other service, or the employment or service of any of our affiliates, any employee or independent contractor thereof or hiring any employee or independent contractor who has left our employment or other service or the employment or service of any of our affiliates within the one-year period (six months, in the case of Mr. Braun), which follows the termination of such employee's or independent contractor's employment or other service with us and our affiliates. The employment agreements also contain provisions that prohibit each of Messrs. Braun and Handy from intentionally interfering with our client or customer relationships (one-year prohibition for Mr. Braun and two years for Mr. Handy), in addition to provisions preventing the executive officers from making statements that may adversely affect or otherwise malign our business or reputation, or that of any of our affiliates, for a period of time following his termination of employment (two years for Mr. Handy and indefinite for Mr. Braun). As described above, if we elect to enforce the non-competition and non-solicitation provisions in Mr. Handy's employment agreement, he will be entitled to a cash payment equal to the Base Severance Amount.

Each of Messrs. Braun and Handy is required to retain in strictest confidence, and not use for his benefit or the benefit of others, except in connection with our business and affairs and those of our affiliates, all confidential matters relating to our business and the business of any of our affiliates and to us and any of our affiliates, learned by the executive officer directly or indirectly from us or any of our affiliates, and is not to disclose such confidential information to anyone outside of our company except with our express written consent and except for confidential information which is at the time of receipt, or thereafter becomes, publicly known through no wrongful act of the executive officer, or is received from a third party not under an obligation to keep such information confidential and without breach of the executive officer's employment agreement.

Golden Parachute Compensation

The descriptions and quantifications of the payments in the table below are intended to comply with Item 402(t) of Regulation S-K, which requires disclosure of information about compensation and benefits that each of the Company's named executive officers will or may receive in connection with the Company Merger. This compensation is referred to as "golden parachute" compensation by applicable SEC disclosure rules, and such compensation is subject to a non-binding, advisory vote of our stockholders, as described below in the section "Advisory Vote Regarding Golden Parachute Compensation."

The following table sets forth estimated amounts of the "golden parachute" compensation that certain executive officers of the Company could receive in connection with the Company Merger. These amounts assume completion of the Company Merger and the termination of each executive officer's

employment on March 31, 2012, and are based on the equity holdings of the named executive officers as of February 3, 2012.

(1)

Represents the aggregate value of the cash severance payments if the named executive officer's employment is terminated following the Company Merger, as described in greater detail above under "—Employment Agreements with Messrs. Braun and Handy." Amounts included in this column are "double-trigger" in nature because the eligibility to receive the payment requires a qualifying termination of employment. Each of the named executive officer's cash severance payments are payable in a lump sum following termination of employment. The estimated amount of each cash severance payment payable to Messrs. Braun and Handy is as follows:

•: Mr. Braun: (a) $400,000 for the cash payment equal to his current annual base salary; and (b) $100,000 for the cash payment equal to his pro-rata maximum annual bonus for fiscal year 2012.
•: Mr. Handy: (a) $1,078,765 for the cash payment equal to 1.99 multiplied by the sum of (1) his current annual base salary, and (2) the greater of (A) the average bonus paid to him over the previous two years and (B) the maximum bonus payable to him for fiscal year 2012; and (b) $542,093 for the cash payment equal to the sum of (1) and (2) above, which would be due to Mr. Handy assuming we elect to enforce the non-competition and non-solicitation provisions in his employment agreement.

(2)

Amounts included in this column are "single-trigger" in nature because the eligibility to receive the payment is conditioned solely on the completion of the Company Merger, without regard to whether there is a corresponding termination of employment. The payments are calculated based on the per share merger consideration of $4.25.

(3)

Represents the value of continued participation in group health and dental plans for one year, in the case of Mr. Braun, or three years, in the case of Mr. Handy, calculated based on the monthly premiums for participation in the plan as of January 1, 2012, and using the assumptions used for financial reporting purposes under GAAP. Amounts included in this column are "double-trigger" in nature because the eligibility to receive the payment requires a qualifying termination of employment.

(4)

Represents the estimated golden parachute excise tax gross-up payment to Mr. Handy. The calculation of the estimated tax gross-up payment is based on a Code Section 4999 golden parachute excise tax rate of 20%, 35% federal income tax rate, 1.45% Medicare tax rate and 7.75% North Carolina state tax rate, and treats the $542,093 payment that would be due to Mr. Handy if we elect to enforce the non-competition and non-solicitation provisions in his employment agreements as reasonable compensation for services following the Company Merger and not subject to the excise tax.

(5)

Represents the aggregate payments to be made in respect of shares of restricted stock that will vest upon the effective time of the Company Merger, as described in greater detail above under "—Equity Compensation Awards."

Table of Contents

(6): Represents the aggregate payments to be made in respect of unvested LTIP Units that will vest immediately prior to the effective time of the Partnership Merger ($129,459) and the conversion of vested LTIP Units into OP Units in connection with the Partnership Merger ($90,444), as described in greater detail above under "—Equity Compensation Awards," and assuming conversion of the LTIP Units into OP Units on a 1-for-1 basis. The actual amount paid in respect of the LTIP Units generally will be based on the actual number of OP Units into which the outstanding LTIP Units are converted in connection with the Partnership Merger.
(7): Mr. Cogdell was a named executive officer in the Company's 2011 definitive proxy statement pursuant to Item 402(a)(3)(iii) of Regulation S-K, and therefore is included in the above table pursuant to the requirements set forth in Instruction 1 to Item 402(t)(2) of Regulation S-K. Mr. Cogdell's employment terminated on November 1, 2011, not in connection with the Company Merger, and he received certain severance benefits. As of February 3, 2012, Mr. Cogdell does not hold any LTIP Units or shares of restricted stock. Accordingly, no amounts are reported in the table for Mr. Cogdell.
(8): Mr. Spencer was a named executive officer in the Company's 2011 definitive proxy statement pursuant to Item 402(a)(3)(i) of Regulation S-K, and therefore is included in the above table pursuant to the requirements set forth in Instruction 1 to Item 402(t)(2) of Regulation S-K. Mr. Spencer's employment terminated on October 31, 2010, not in connection with the Company Merger, and he received certain severance benefits. As of February 3, 2012, Mr. Spencer does not hold any LTIP Units or shares of restricted stock. Accordingly, no amounts are reported in the table for Mr. Spencer.

Erdman Sale

Continued Benefits

Ventas has agreed that it will, and will cause the Surviving Company after the effective time of the Company Merger to:

•: honor each material benefit plan of the Company and its subsidiary, which we refer to as the Company Benefit Plans, other than any Company Benefit Plan that covers only employees of the Erdman Companies, and any related funding arrangements of such Company Benefit Plans in accordance with their terms;
•: honor all rights to vacation, personal and sick days accrued by employees of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership under the Company Benefit Plans and reflected in the records of the Company through and including the effective time of the Company Merger; and
•: until the date that is 12 months after the effective time of the Company Merger, provide, pension, welfare and fringe benefits (other than incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) to the employees of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership that are in the aggregate no less favorable than the pension, welfare and fringe benefits (other than incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) that, at the election of Ventas, are provided (i) to such

Table of Contents

employees pursuant to Company Benefit Plans as of the date of the merger agreement or (ii) by Ventas to its similarly situated employees.

However, Ventas is not obligated to continue any particular Company Benefit Plan nor is Ventas prohibited from terminating (or causing the termination of) the employment of any employee of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership at any time after the closing of the Mergers for any reason (or no reason). See "The Merger Agreement—Employee Benefit Matters" beginning on page 74.

Tax Protection Agreements with Messrs. Cogdell, Handy and Smoak

Mr. James W. Cogdell, the former Executive Chairman of the Board, Mr. Charles M. Handy, one of the Company's current executive officers, and Dr. Randolph D. Smoak, Jr. M.D., one of the Company's directors, have entered into "tax protection agreements." The amount of payments, if any, pursuant to existing tax protection agreements entered into by such individuals and the Operating Partnership is not currently determinable.

Arrangements with the Surviving Corporation

As of the date of this proxy statement, none of our executive officers has entered into any agreement, arrangement or understanding with Ventas or its affiliates regarding employment with, or the right to participate in the equity of, Ventas. In addition, no member of our board of directors has entered into any agreement, arrangement or understanding with Ventas or its affiliates regarding the right to participate in the equity of Ventas.

Material U.S. Federal Income Tax Consequences of the Company Merger

Federal Income Tax Consequences to the Company

In the Company Merger, if the Company is merged with and into MergerSub with MergerSub surviving, the Company Merger will be treated for U.S. federal income tax purposes as a taxable sale by the Company of all of its assets to MergerSub in return for cash, in the amount of the aggregate merger consideration plus the assumption of the Company's liabilities, followed by a taxable liquidation of the Company under section 331 of the Code. Under these circumstances the Company will be deemed to have distributed the merger consideration to the Company stockholders in connection with the deemed liquidation, and the liquidating distribution will be treated as a dividend for purposes of the dividend paid deduction to the extent of the Company's earnings and profits and thus should be sufficient to satisfy the Company's requirement to distribute at least 90% of its REIT taxable income for the taxable year of the merger. Alternatively, if MergerSub is merged with and into the Company with the Company surviving, Ventas will be deemed to have acquired all of the Company's stock from its stockholders in exchange for the aggregate merger consideration, and stockholders will generally be deemed to have sold their shares of Company stock to Ventas in a taxable transaction. Under these circumstances the Company will be deemed to liquidate immediately thereafter in a nontaxable transaction pursuant to Section 332 of the Code, provided that the Company will be entitled to a dividend paid deduction to the extent of the Company's earnings and profits.

Exchange of Shares of Company Common Stock or Series A Preferred Stock for Cash Pursuant to the Merger Agreement

If the Company is merged with and into MergerSub with MergerSub surviving, U.S. stockholders who receive the per share merger consideration or the preferred per share merger consideration in exchange for shares of Company common stock or Series A Preferred Stock, respectively, will be treated for U.S. federal income tax purposes as having received a liquidating distribution of cash in exchange for their shares in a taxable transaction and will recognize capital gain or loss in an amount

Table of Contents

equal to the difference between the total cash consideration received by each such stockholder and such respective stockholder's adjusted basis in their shares of Company common stock or Series A Preferred Stock, as applicable. If MergerSub is merged with and into the Company with the Company surviving, U.S. stockholders who receive the per share merger consideration or the preferred per share merger consideration in exchange for shares of Company common stock or Series A Preferred Stock, respectively, will be treated for U.S. federal income tax purposes as having sold their shares of Company common stock or Series A Preferred Stock, as applicable, in exchange for the per share merger consideration or the preferred per share merger consideration, as applicable, and will recognize capital gain or loss in an amount equal to the difference between the total cash consideration received by each such stockholder and such respective stockholder's adjusted basis in their shares of Company common stock or Series A Preferred Stock, as applicable. Capital gain of a non-corporate U.S. stockholder arising in connection with the exchange of their shares of Company common stock or Series A Preferred Stock, as applicable, for cash will generally be taxed at a maximum rate of 15% provided that the stockholder has held such shares for a period greater than one year.

A U.S. stockholder who has held their shares of Company common stock or Series A Preferred Stock, as applicable, for six months or less at the effective time of the Company Merger, taking into account the holding period rules of Section 246(c)(3) and (4) of the Code, and who recognizes a capital loss with respect to those shares will be treated as recognizing a long-term, rather than short-term, capital loss to the extent of any capital gain dividends previously received by such stockholder from the Company. The deductibility of capital losses, in general, is subject to limitations. With respect to stockholders of the Company that acquired such shares at different times and/or different prices, gain or loss must be calculated and accounted for separately for each block of shares.

Exchange of OP Units for Cash Pursuant to the Partnership Merger

Holders of OP Units who exchange their OP Units for cash in connection with the Partnership Merger (including holders of LTIP Units which are converted to OP Units in connection with the Partnership Merger, generally based upon the ratio which the portion of their adjusted capital account balance properly allocable to each LTIP Unit at such time bears to the portion of the Company's adjusted capital account balance properly allocable to each OP Unit held by the Company at such time), will be treated as selling their OP Units to Ventas in exchange for the per share merger consideration and will recognize capital gain or loss in an amount equal to the difference between (x) the sum of the per share merger consideration received in the Partnership Merger plus the amount of the Operating Partnership's liabilities allocated to such partner for federal income tax purposes immediately prior to the Partnership Merger and (y) such partner's adjusted basis in their interest in the Operating Partnership. Capital gain of a non-corporate U.S. holder of OP Units arising in connection with the Partnership Merger will generally be taxed at a maximum rate of 15% provided that the partner has held such OP Units for a period greater than one year.

As a result of the Partnership Merger, certain holders of OP Units may be entitled to receive additional payments pursuant to existing "tax protection agreements" entered into by such limited partners and the Operating Partnership. The determination of the amount of any such payments required to be made to any limited partner as a result of the Partnership Merger will be made by Ventas. Any payment received by a limited partner of the Operating Partnership pursuant to the terms of the applicable tax protection agreement will be subject to U.S. federal income tax at ordinary income rates.

Backup Withholding and Information Reporting

Under U.S. federal income tax law, consideration to be received in the Company Merger may be subject to information reporting and a 28% backup withholding tax. Backup withholding generally will not apply to payment made to certain exempt recipients such as a corporation of financial institution or

Table of Contents

to a stockholder which certifies such stockholder's taxpayer identification number and certain other required information or provides a certificate of foreign status. Backup withholding is not an additional tax. If backup withholding applies, the amount withheld will be allowed as a refund or credit against such stockholder's U.S. federal income tax liability, provided the required information is furnished by the stockholder to the Internal Revenue Service on a timely basis.

Federal Income Tax Consequences for Non-U.S. Holders of Company Common Stock, Series A Preferred Stock or Partnership Units

If the Company is merged with and into MergerSub with MergerSub surviving, non-U.S. holders of Company common stock or Series A Preferred Stock, as applicable, who receive the per share merger consideration or preferred per share merger consideration, respectively, in exchange for shares of Company common stock or Series A Preferred Stock, as applicable, will be treated for U.S. federal income tax purposes as having received a liquidating distribution of cash in exchange for their shares, and will be subject to tax under the Foreign Investment in Real Property Tax Act of 1980, which we refer to as FIRPTA, and withholding at the rate of 35% to the extent such distribution is attributable to gain deemed recognized by the Company with respect to its U.S. real property interests in connection with the Company Merger regardless of whether overall gain or loss in recognized in connection with the Company Merger. Non-U.S. stockholders should consult their tax advisors regarding the possibility of obtaining a refund of such withholding tax. If MergerSub is merged with and into the Company with the Company surviving, non-U.S. holders of Company common stock or Series A Preferred Stock, as applicable, who receive the per share merger consideration or preferred per share merger consideration, respectively, in exchange for shares of Company common stock or Series A Preferred Stock, as applicable, will be treated for U.S. federal income tax purposes as having sold their Company common stock or Series A Preferred Stock, as applicable, to Ventas in exchange for the per share merger consideration or preferred per share merger consideration, respectively, and, provided that the Company qualifies as a "domestically controlled" REIT, will not be subject to U.S. federal income tax on gain they recognize as a result of the Company Merger. The Company will qualify as a "domestically controlled" REIT if, at all times during the five-year period preceding the closing of the Company Merger, less than 50% in value of the Company's stock has been held, directly or indirectly, by non-U.S. stockholders. The Company believes that it qualifies and will continue to qualify as a "domestically controlled" REIT.

A non-U.S. holder of OP Units will be subject to FIRPTA withholding at the rate of 10% of the gross proceeds deemed received in connection with the Partnership Merger (including proceeds attributable to the reduction in such holder's share of allocated liabilities). Non-U.S. holders of OP Units should consult their tax advisors regarding the possibility of obtaining a refund of such withholding tax.

The U.S. federal income tax consequences described above are not intended to constitute a complete description of all tax consequences relating to the Company Merger. Because individual circumstances may differ, each stockholder should consult the stockholder's tax advisor regarding the applicability of the rules discussed above to the stockholder and the particular tax effects to the stockholder of the Company Merger in light of such stockholder's particular circumstances and the application of state, local and foreign tax laws.

Regulatory Approvals and Notices

The Company Merger will not require any regulatory approval or notice, except as may be required under the Exchange Act, the Securities Act and the rules and regulations of the NYSE, and the filing and acceptance for record of the merger filing, as required by the Maryland General Corporation Law, or MGCL.

Litigation Related to the Company Merger

On December 29, 2011, a complaint was filed in the Superior Court for State of North Carolina, Mecklenburg County against the Company, the Company's directors and Ventas on behalf of a putative class of similarly situated investors, alleging that the Company's board of directors breached their fiduciary duties regarding the Company Merger and that Ventas aided and abetted the alleged breach of fiduciary duties. Beginning on January 4, 2012, six other putative class action suits were filed in the Maryland Circuit Court for Baltimore City against the same defendants and alleging similar breach of fiduciary duty and aiding and abetting claims, although certain complaints also named the Operating Partnership, MergerSub and OP MergerSub as defendants. The cases pending in Maryland were consolidated by the Court on January 31, 2012. On February 3, 2012, the plaintiff in the North Carolina action filed an amended complaint. All of the pending cases ask that the Company Merger be enjoined and seek other unspecified monetary relief. On January 27, 2012, the Company also received a letter from an entity purporting to be a stockholder of the Company demanding that the board terminate the Company Merger and the sale of the Erdman business and that the board conduct an investigation into the Company Merger and the sale of the Erdman business. The letter also made a request for access to certain books and records of the Company related to the Company Merger and the sale of the Erdman business.

THE MERGER AGREEMENT

This section describes the material terms of the merger agreement but does not purport to describe all of the terms of the merger agreement. The description in this section and elsewhere in this proxy statement is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached asAnnex A and is incorporated by reference into this proxy statement. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. We encourage you to read the merger agreement carefully and in its entirety because it is the legal document that governs the Company Merger. This section is not intended to provide you with any factual information about us. Such information can be found elsewhere in this proxy statement and in the public filings we make with the SEC, as described in the section entitled, "Where You Can Find More Information" beginning on page 89.

Explanatory Note Regarding the Merger Agreement

The merger agreement is included to provide you with information regarding its terms. Factual disclosures about the Company contained in this proxy statement or in the Company's public reports filed with the SEC may supplement, update or modify the factual disclosures about the Company contained in the merger agreement. The representations, warranties and covenants made in the merger agreement by the Company, the Operating Partnership, Ventas, MergerSub and OP MergerSub were qualified and subject to important limitations agreed to by the Company, the Operating Partnership, Ventas, MergerSub, and OP MergerSub in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purposes of establishing the circumstances in which a party to the merger agreement may have the right not to consummate the Mergers if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties may also be subject to a contractual standard of materiality different from those generally applicable to stockholders and reports and documents filed with the SEC and in some cases were qualified by the matters contained in the disclosure schedule that the Company delivered in connection with the merger agreement, which disclosures were not reflected in the merger agreement. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement, may have changed since the date of the merger agreement and subsequent developments or new information qualifying a representation or warranty may have been included in this proxy statement. Accordingly, you should not rely on the representations and warranties in the merger agreement (or the summaries contained herein) as characterizations of the actual state of facts about the Company or Ventas. The representations and warranties in the merger agreement and the description of them in this document should not be read alone but instead should be read in conjunction with the other information contained in the reports, statements and filings we publicly file with the SEC. Such information can be found elsewhere in this proxy statement and in the public filings we make with the SEC, as described in the section entitled "Where You Can Find More Information" beginning on page 89.

Effects of the Mergers; Directors and Officers; Organizational Documents

The merger agreement provides that (i) either (A) MergerSub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of Ventas, or (B) the Company will merge with and into MergerSub, with MergerSub surviving as a wholly-owned subsidiary of Ventas (we refer to this merger as the Company Merger, and to the surviving entity as the Surviving Company), and (ii) OP MergerSub will merge with and into the Operating Partnership, with the

Table of Contents

Operating Partnership surviving as a wholly-owned subsidiary of Ventas (we refer to this merger as the Partnership Merger and, together with the Company Merger, the Mergers).

The directors of MergerSub immediately prior to the effective time of the Company Merger will be the directors of the Surviving Company until their respective successors are duly elected or appointed and qualified or until their earlier death, resignation or removal. The officers of MergerSub immediately prior to the effective time of the Company Merger will be the initial officers of the Surviving Company, each to hold office in accordance with the charter and bylaws of the Surviving Company.

The charter of MergerSub in effect immediately before the effective time of the Company Merger will be the charter of the Surviving Company until thereafter amended in accordance with applicable law, except that the name of the Surviving Company shall be "TH Holdings, Inc." Following the effective time of the Partnership Merger, the certificate of limited partnership of the Operating Partnership shall continue in effect as the certificate of limited partnership of the surviving partnership until further amended in accordance with applicable law.

Following the completion of the Company Merger, the Company common stock will be delisted from the NYSE and deregistered under the Exchange Act and cease to be publicly traded.

Closing and Effective Time of the Merger

The closing of the Mergers will take place at (i) 10:00 a.m. local time on the third business day following the date on which the last of the conditions to closing of the Mergers (described under "The Merger Agreement—Conditions to the Mergers" beginning on page 76) has been satisfied or waived (other than those conditions that by their nature are to be satisfied at the closing of the Mergers, but subject to the satisfaction or waiver of those conditions) or (ii) at such other time as Ventas and the Company may agree; provided that, notwithstanding the foregoing, Ventas, in its sole discretion, has the right to extend the closing of the Mergers (x) for up to 45 days for any reason and (y) for up to an additional 30 days for the purpose of obtaining any consent, amendment or waiver from any lenders of the Company and/or its subsidiaries, any counterparties to joint venture or partnership agreements, and/or any lessors under ground leases, but Ventas may not extend the closing for such purposes to any date after May 15, 2012.

Assuming timely satisfaction of the necessary closing conditions, we anticipate that the Mergers will be completed during the second quarter of 2012. The effective time of the Company Merger will occur when duly executed articles of merger or other appropriate documents are accepted for record by the State Department of Assessments and Taxation of Maryland, or such later time as Ventas and the Company have agreed (not to exceed one business day after the merger filing is accepted for record) and as designated in the merger filing in accordance with the Maryland General Corporation Law as the effective time of the Company Merger. The effective time of the Partnership Merger will occur when a duly executed certificate of merger or other appropriate documents are filed with the Delaware Secretary of State, or such later time as Ventas and the Company have agreed and as designated in the partnership merger filing in accordance with the Delaware Revised Uniform Limited Partnership Act as the effective time of the Partnership Merger. In no event will the Partnership Merger effective time be more than 30 days after the Partnership Merger filing is filed with the Delaware Secretary of State.

Treatment of Company Common Stock, Series A Preferred Stock, Operating Partnership Units, Restricted Stock and LTIP Units

Common Stock

At the effective time of the Company Merger, each share of Company common stock issued and outstanding immediately prior to the effective time of the Company Merger (except for the excluded

Table of Contents

shares) will automatically convert into the right to receive the per share merger consideration, without interest and subject to deduction for any required withholding tax. Shares of Company common stock owned by Ventas, MergerSub, any other subsidiary of Ventas, the Company or any Company subsidiary will be cancelled without payment of any consideration. Each share of common stock of MergerSub that remains outstanding immediately prior to the effective time of the Company Merger will convert into one share of common stock of the Surviving Company.

Series A Preferred Stock

At the effective time of the Company Merger, each share of Series A Preferred Stock of the Company issued and outstanding immediately prior to the effective time of the Company Merger (except for the excluded preferred shares) will automatically convert into the right to receive the preferred per share merger consideration, without interest and subject to deduction for any required withholding tax, plus all accrued and unpaid dividends thereon through and including the date on which the Company Merger closes.

Operating Partnership Units

At the effective time of the Partnership Merger, each unit representing a partnership interest in the Operating Partnership, other than LTIP Units, issued and outstanding, which we refer to as OP Units or an OP Unit, immediately prior to the effective time of the Partnership Merger (except for the excluded OP Units) will automatically convert into the right to receive the per share merger consideration, without interest and subject to deduction for any required withholding tax. The general partnership interest of the Operating Partnership will remain outstanding and will be the only general partnership interest in the Operating Partnership after the effective time of the Partnership Merger. Each Series A Preferred Partnership Unit will automatically be cancelled without payment of any consideration.

Restricted Stock

At the effective time of the Company Merger, each share of Company common stock subject to restrictions on transfer or forfeiture granted under the Company's equity plans or otherwise that is outstanding immediately prior to the effective time of the Company Merger will become fully vested and all such shares will automatically convert into the right to receive the per share merger consideration, without interest, and subject to deduction for any required withholding tax. The Company will take such actions prior to the effective date of the Company Merger to terminate any Company equity plans and to ensure that following the Company Merger, Ventas will not be required to deliver additional shares or interests in the Company or Ventas pursuant to any of the Company's equity plans.

LTIP Units

Immediately before the effective time of the Partnership Merger, each unvested LTIP Unit granted under the Operating Partnership's long-term incentive plans or otherwise that is outstanding at such time will become fully vested and each vested LTIP Unit will automatically convert into an OP Unit, or fraction thereof, based on the adjusted capital account balance allocable to such LTIP Unit immediately prior to the Partnership Merger. Accordingly, holders of LTIP Units that are so converted generally will receive the per share merger consideration, without interest, less any applicable withholding taxes. The Operating Partnership will take such actions prior to the effective date of the Partnership Merger to terminate any of the Operating Partnership's long-term incentive plans and to ensure that, following the Partnership Merger, the Operating Partnership will not be required to deliver additional units or interests in the Operating Partnership pursuant to any of the Operating Partnership's long-term incentive plans.

Exchange and Payment Procedures

At or prior to the effective time of the Company Merger, Ventas will deposit, or will cause to be deposited, with the paying agent a cash amount equal to the aggregate per share merger consideration and the aggregate preferred per share merger consideration. Within five business days after the effective time of the Company Merger, Ventas shall cause the paying agent to mail to each holder of record of outstanding shares of Company common stock or Series A Preferred Stock immediately prior to the effective time of the Company Merger, whether represented by stock certificates or in book entry form, whose shares were converted into the right to receive the per share merger consideration or the preferred per share merger consideration, a letter of transmittal in customary form and instructions for use in effecting the surrender of the certificates or book entry shares in exchange for the per share merger consideration or the preferred per share merger consideration, as applicable.

No later than five business days following the effective time of the Company Merger, Ventas shall cause the paying agent to mail to each holder of record of OP Units that were converted immediately prior to the effective time of the Partnership Merger into the right to receive the per share merger consideration a letter of transmittal in customary form and instructions for use in effecting the surrender of the units in exchange for the per share merger consideration.

You should not return your stock certificates with the enclosed proxy card, and you should not forward your stock certificates to the paying agent without a letter of transmittal.

You will not be entitled to receive the per share merger consideration or the preferred per share merger consideration until you deliver a duly completed and executed letter of transmittal to the paying agent. If your shares are certificated, you must also surrender your stock certificate or certificates to the paying agent. If ownership of your shares is not registered in the transfer records of the Company, a check for any cash to be delivered will only be issued if the applicable letter of transmittal is accompanied by all documents reasonably required by Ventas to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable.

No interest will be paid or accrued on the cash payable as the per share merger consideration or the preferred per share merger consideration upon the surrender of your certificates or book-entry shares. Ventas and the paying agent will be entitled to deduct and withhold any applicable taxes from the per share merger consideration and the preferred per share merger consideration. Any sum that is withheld will be deemed to have been paid to the person with regard to whom it is withheld.

From and after the effective time of the Company Merger, there will be no transfers on our stock transfer books of shares of Company common stock or Series A Preferred Stock that were outstanding immediately prior to the effective time of the Company Merger. If, after the effective time of the Company Merger, a certificate is presented to Ventas or the paying agent for transfer, such certificate will be cancelled and, subject to compliance with the exchange procedures set forth in the merger agreement, exchanged for the cash amount to which such person is entitled pursuant to the merger agreement. No transfers of OP Units will be permitted after the effective time of the Partnership Merger.

Any portion of the per share merger consideration or preferred per share merger consideration deposited with the paying agent that remains undistributed on the one-year anniversary of the effective time of the Company Merger will be delivered to Ventas upon demand. Record holders of Company common stock (other than the excluded shares), Series A Preferred Stock (other than the excluded preferred shares) or OP Units (other than the excluded OP Units) who have not complied with the above-described exchange and payment procedures may thereafter only look to Ventas, Surviving Company or the Operating Partnership for payment of the per share merger consideration. None of Ventas, Surviving Company, the Operating Partnership, the paying agent or any other person will be

Table of Contents

liable to any person for any cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar laws.

If you have lost a certificate, or if it has been stolen or destroyed, then, before you will be entitled to receive the per share merger consideration, you will have to make an affidavit of the loss, theft or destruction of that certificate, and, if required by Ventas or the paying agent, post a bond in a customary amount as indemnity against any claim that may be made against it or the Company with respect to such certificate. These procedures will be described in the letter of transmittal that you will receive, which you should read carefully in its entirety.

Conduct of Our Business Pending the Mergers

Under the merger agreement, the Company and the Operating Partnership agreed that, subject to certain exceptions set forth in the merger agreement and the matters contained in the disclosure schedule delivered by the Company in connection therewith, between the date of the merger agreement and the effective time of the Company Merger, unless Ventas gives its prior written approval (which cannot be unreasonably withheld, delayed or conditioned), the Company, the Operating Partnership and the Company's other subsidiaries (other than any Erdman Company) will cause its businesses to be carried on in the ordinary course consistent with past practice and will use its reasonable best efforts to preserve intact its business, assets, organization, goodwill and current beneficial relationships, including with customers, suppliers, directors, officers and key employees, and to keep available the services of its officers and key employees to maintain its qualification as a REIT.

Subject to certain exceptions set forth in the merger agreement and the matters contained in the disclosure schedule delivered by the Company in connection therewith, we will not, and we will not permit our subsidiaries to, take any of the following actions:

•: sell, pledge, lease, dispose of, exclusively license or encumber or grant any third party any rights with respect to any property or assets, except for the granting of mortgages and security interests in connection with the refinancing of indebtedness existing on the date of the merger agreement and that matures at or prior to the closing, without any penalty or premium, the dispositions of immaterial assets or the consummation of the Erdman Sale in accordance with the Erdman purchase agreement;

Restrictions on Solicitation of Other Acquisition Proposals

Under the merger agreement, we are subject to customary "no-shop" restrictions on our ability to solicit alternative acquisition proposals from third parties and to provide information to and engage in discussions with third parties regarding alternative acquisition proposals. Except as permitted by the terms of the merger agreement described below, we have agreed that the board of directors will not: (i) withhold, withdraw, qualify or modify (or publicly propose or resolve to do so) in any manner adverse to Ventas, the Company recommendation, or adopt, approve or publicly recommend, endorse or otherwise declare advisable the adoption of any acquisition proposal; or (ii) cause or permit the Company to enter into any alternative acquisition agreement relating to an acquisition proposal.

We have agreed that we, the Operating Partnership and our other subsidiaries will not, and will use reasonable best efforts to cause their respective officers, directors, employees, consultants, agents, advisors and other representatives not to, directly or indirectly:

•: initiate, solicit, knowingly facilitate or encourage (including by way of providing non-public information) the submission of any acquisition proposal or any inquiries, proposals or offers that reasonably may be expected to lead to, any acquisition proposal;
•: engage in any discussions or negotiations with respect thereto or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations;
•: approve, adopt or recommend, or propose to approve, adopt or recommend, an acquisition proposal or enter into any agreement providing for or relating to an acquisition proposal;
•: enter into any agreement or agreement in principle requiring the Company or the Operating Partnership to abandon, terminate or fail to consummate the Mergers or breach its obligations under the merger agreement; or
•: terminate, waive, amend, release or fail to enforce any standstill agreement.

Table of Contents

We, the Operating Partnership and our subsidiaries have also agreed to immediately cease any and all discussions, negotiations or communication with any person with respect to any acquisition proposal and to request the prompt return or destruction of all confidential information previously furnished to any person with which the Company or its representatives have had discussions regarding any acquisition proposal within 12 months prior to the date of the merger agreement. However, at any time prior to the time our stockholders approve the Company Merger, if we receive an unsolicited written acquisition proposal from any person that did not result from a breach of our obligations under the preceding paragraph, and that our board of directors determines in good faith (after consultation with our outside counsel and financial advisor) constitutes or is reasonably likely to lead to a superior proposal, we may:

•: furnish information with respect to the Company, the Operating Partnership and the other subsidiaries of the Company to the person making the acquisition proposal (pursuant to an acceptable confidentiality agreement); provided that any non-public information concerning the Company, the Operating Partnership or any other subsidiary of the Company provided to such person is promptly provided to Ventas to the extent not previously provided; and
•: participate in discussions or negotiations with such person regarding the acquisition proposal; provided, that we shall notify Ventas in writing within 24 hours of any such determination by the Company's board of directors that such acquisition proposal constitutes or is reasonably likely to constitute a superior proposal and that failure to take such action would be reasonably likely to lead to a breach of the duties of the Company's directors to the Company's stockholders under applicable law.

We shall notify Ventas within 24 hours of the receipt of any acquisition proposal and shall, in any such notice to Ventas, indicate the identity of the person making the acquisition proposal and the material terms and conditions of the acquisition proposal. In addition, we shall provide to Ventas within 24 hours copies of any written documentation received that is material to understanding the acquisition proposal. We shall not, and will cause our subsidiaries not to, take any action to exempt any person from the restrictions on "business combinations" contained in any applicable laws, or terminate, waive, amend or modify any provision of any existing confidentiality agreement to which we or any of our subsidiaries is a party, and we shall use reasonable best efforts to, and shall cause our subsidiaries, to use reasonable best efforts to, enforce the provisions of any such agreement (provided that, notwithstanding the foregoing, we shall not be required to take, or be prohibited from taking, any action otherwise prohibited by this sentence if and only, the board of directors has determined in good faith, after considering the advice of outside legal counsel, that taking such action or failing to take such action, as the case may be, would be reasonably likely to result in a breach of the duties of the directors to our stockholders under applicable law). The board of directors will promptly consider in good faith (in consultation with our outside legal counsel and financial advisor) any proposed alteration of the terms of the merger agreement or the Mergers proposed by Ventas in response to any acquisition proposal.

At any time before the Company Merger is approved by our stockholders, we may terminate the merger agreement and enter into an alternative acquisition agreement with respect to a superior proposal, so long as we comply with certain terms of the merger agreement, including paying a termination fee and expense reimbursement to Ventas. See "The Merger Agreement—Termination Fees" beginning on page 79. In addition, at any time prior to the time our stockholders approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, our board of directors may effect a change of recommendation if it determines in good faith, after consultation with outside legal counsel, that failure to do so would be reasonably likely to lead to a breach of the duties of the directors to our stockholders under applicable law.

Table of Contents

However, prior to terminating the merger agreement in order to enter into an alternative acquisition agreement with respect to a superior proposal:

•: we must not have breached, in any material respect, the terms of the merger agreement described in this section "Restrictions on Solicitation of Other Acquisition Proposals";
•: the Company's board of directors must have determined in good faith (after consultation with the Company's outside counsel and financial advisor) that the acquisition proposal is a superior proposal;
•: the Company's board of directors must have determined in good faith, after consultation with outside counsel, that failure to enter into such alternative acquisition agreement would be reasonably likely to constitute a breach of the duties of the Company's directors to the Company's stockholders under applicable law;
•: we must notify Ventas at least three business days in advance of taking such action of our intention to terminate the merger agreement to enter into a definitive agreement with respect to such superior proposal, which notice shall specify the material terms and conditions of the superior proposal (including the identity of the party making the superior proposal), and shall be accompanied by a copy of a draft of the definitive agreement proposed to be entered into with respect to the superior proposal;
•: we shall negotiate in good faith with Ventas (to the extent Ventas desires to do so) during the three business-day period to make such adjustments to the terms and conditions of the merger agreement such that such acquisition proposal would no longer constitute a superior proposal; and
•: our board of directors shall have confirmed (after taking into account any such adjustments to the terms and conditions of the merger agreement) that the acquisition proposal continues to be a superior proposal.

Nothing contained in the merger agreement shall prohibit the Company from (i) taking and disclosing to our stockholders a position contemplated by Rule 14e-2(a) under the Exchange Act, or (ii) making any other disclosure to our stockholders if our board of directors determines in good faith (after consultation with outside counsel) that the failure to so disclose would be reasonably likely to lead to a breach of the duties of the directors to our stockholders under applicable law. However, such communications may be considered a change of recommendation entitling Ventas to terminate the merger agreement and receive a termination fee and expense reimbursement, as provided in the merger agreement.

In this proxy statement we refer to any proposal or offer whether in one transaction or a series of related transactions (i) for a merger, consolidation, share or equity interest exchange, dissolution, recapitalization or other business combination to which the Company, the Operating Partnership or any subsidiary of the Company that would constitute a "significant subsidiary" (as defined in Rule 1-02 of Regulation S-X, but substituting 25% for references to 10% therein) is a constituent party, (ii) for the issuance, sale or other disposition by the Company or any subsidiary of the Company (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing 25% or more of the outstanding voting interests in the Company, the Operating Partnership or any subsidiary of the Company, (iii) for the sale or other disposition, directly or indirectly, by merger, consolidation, share exchange or any similar transaction, of any assets (including equity securities of any subsidiary of the Company) of the Company, the Operating Partnership or the subsidiaries of the Company representing 25% or more of the consolidated assets of the Company and its subsidiaries, (iv) tender offer or exchange offer in which any person or "group" (as such term is defined under the Exchange Act) offers to acquire beneficial ownership, or the right to acquire beneficial ownership, of 25% or more of the

Table of Contents

outstanding shares of Company common stock or (v) transaction which is similar in form, substance or purpose to any of the foregoing transactions, in each case other than the transactions contemplated by merger agreement, as an acquisition proposal.

In this proxy statement we refer to any unsolicited bona fide written acquisition proposal (with the percentages set forth in the definition of such term changed from 25% to 50%) received after the date of the merger agreement that our board of directors determines in good faith (after consultation with our outside counsel and financial advisor), after taking into account all the terms and conditions of such proposal and the merger agreement (including any proposal by Ventas to amend the terms of the merger agreement, and including in each case the risks, probabilities and timing of consummation) and the person making the proposal, would, if consummated, be more favorable to the stockholders of Company from a financial point of view than the transactions contemplated by the merger agreement and (ii) if accepted, is reasonably likely to be consummated and for which financing, if a transaction involving cash consideration (whether in whole or in part), is then fully committed or reasonably determined to be available by the Company's board of directors and which is not subject to any condition to consummation based on the availability of financing, as a superior proposal.

Stockholders Meeting

We are required to take all action in accordance with Maryland law and our charter and bylaws necessary to duly call, give notice of and convene a meeting of our common stockholders as promptly as reasonably practicable, but in no event later than 45 days following the conclusion of any SEC review of this proxy statement, to consider and vote upon the approval of the Company Merger. Subject to the provisions of the merger agreement discussed above under "The Merger Agreement—Restrictions on Solicitation of Other Acquisition Proposals," our board of directors will recommend that our stockholders vote to approve the Company Merger pursuant to the terms and conditions set forth in the merger agreement, include such recommendation in this proxy statement and solicit approval of the Company Merger.

Erdman Purchase Agreement; Erdman Proceeds

We will, and will cause TRS Holdings and the Erdman Companies to, use our respective reasonable best efforts to close the Erdman Sale prior to the closing of the transactions contemplated under the merger agreement. We agree not to, and to cause TRS Holdings and the Erdman Companies not to, make any amendment or modification to, or waive, terminate or assign any rights under the Erdman purchase agreement or any agreement contemplated thereby without the prior written consent of Ventas.

As described further under "Sale of the Erdman Business—Go-Shop Period", in the event TRS Holdings enters into a substitute purchase agreement during the go-shop period, it must pay to Madison DB a termination fee of $400,000 and, pursuant to the terms of the merger agreement, the Company and the Operating Partnership would, prior to consummation of the Mergers, distribute to the holders of the Company common stock and the OP Units and LTIP Units, respectively, an amount in cash equal to the net proceeds (after deduction of the $400,000 termination fee and any incremental expenses associated with the go-shop process) from the sale of the Erdman Companies pursuant to the substitute purchase agreement, which we refer to as the Erdman Distribution.

Direction of Merger

Ventas shall have the right, exercisable by written notice to us not less than two business days prior to the closing date of the Company Merger, to cause the Company Merger to be effected by either (i) merging MergerSub with and into the Company, with the Company surviving as a wholly-owned subsidiary of Ventas, or (ii) merging the Company with and into MergerSub, with MergerSub surviving

Table of Contents

as a wholly-owned subsidiary of Ventas, at its sole discretion. Regardless of the manner in which the Company Merger is structured, you will not be entitled to own any shares of the capital stock of the Surviving Company after the Company Merger is completed.

Efforts to Consummate the Mergers

We and the other parties to the merger agreement have agreed to use our (and to cause our respective subsidiaries to use their) respective reasonable best efforts to take all actions and do all things necessary, proper or advisable under the merger agreement and applicable laws to consummate the Mergers and any other transactions contemplated by the merger agreement as promptly as practicable. This includes using reasonable efforts to:

•: make any filing with and obtain any consent, authorization, order or approval of, or any exemption by, any governmental entity that is required to be made or obtained in connection with the Mergers;
•: prepare, execute and deliver such instruments and take or cause to be taken such actions as any other party to the merger agreement shall reasonably request;
•: after consultation with the other parties to the merger agreement, obtain any consent, waiver, approval or authorization from any third party required in order to maintain in full force and effect any of the Company's permits or the Company's contracts, licenses or other rights following the Mergers; and
•: to resist, contest or defend any suit, claim, action or proceeding (including administrative or judicial actions and proceedings) challenging the Mergers or the completion of the transactions contemplated under the merger agreement.

Each party to the merger agreement has agreed to furnish to each other party such necessary information and reasonable assistance as such other party may reasonably request in connection with the foregoing.

Subject to applicable laws and the instructions of any governmental entity, we and Ventas have agreed to keep each other reasonably apprised of the status of matters relating to the completion of the transactions contemplated in the merger agreement, including promptly furnishing the other with copies of notices or other written communications received by us or Ventas, as the case may be, or any of our respective subsidiaries, from any governmental entity or third party with respect to such transactions, and, to the extent practicable under the circumstances, have agreed to provide the other party and its counsel with the opportunity to participate in any meeting with any governmental entity in respect of any filing, investigation or other inquiry in connection with the transactions contemplated in the merger agreement.

Employee Benefit Matters

Ventas has agreed that it will, and will cause the Surviving Company after the effective time of the Company Merger to:

•: honor each Company Benefit Plan, other than any Company Benefit Plan that covers only employees of the Erdman Companies, and any related funding arrangements of such Company Benefit Plans in accordance with their terms;
•: honor all rights to vacation, personal and sick days accrued by employees of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership under the Company Benefit Plans and reflected in the records of the Company through and including the effective time of the Company Merger; and

Table of Contents

•: until the date that is 12 months after the effective time of the Company Merger, provide, pension, welfare and fringe benefits (other than incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) to the employees of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership that are in the aggregate no less favorable than the pension, welfare and fringe benefits (other than incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) that, at the election of Ventas, are provided (i) to such employees pursuant to Company Benefit Plans as of the date of the merger agreement or (ii) by Ventas to its similarly situated employees.

With respect to any employee benefit plans in which any employees of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership first become eligible to participate on or after the effective time of the Company Merger, and in which the employees of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership did not generally participate before the effective time of the Company Merger, Ventas, to the extent applicable, has agreed to:

•: waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the employees of the acquired companies under any such new plans in which such employees may be eligible to participate after the effective time of the Company Merger, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Company Benefit Plan;
•: provide each employee of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership with credit for any co-payments and deductibles paid during the calendar year in which the effective time of the Company Merger occurs (to the same extent such credit was given under the analogous Company Benefit Plan before the effective time of the Company Merger) in satisfying any applicable deductible or out-of-pocket requirements under any such new plan in which such employees may be eligible to participate after the effective time of the Company Merger;
•: recognize all service of such employees for all purposes (including purposes of eligibility to participate, vesting, entitlement to benefits and benefit accrual (other than under any defined benefit plan)) in any such new plan in which such employees may be eligible to participate after the effective time of the Company Merger; and
•: with respect to flexible spending accounts, provide each employee of the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership with a credit for any salary reduction contributions made thereto and a debit for any expenses incurred thereunder with respect to the plan year in which the effective time of the Company Merger occurs; provided, that the foregoing shall not require duplication of benefits.

If requested by Ventas prior to the effective time of the Company Merger, the Company, the Operating Partnership and any other subsidiary of the Company, as applicable, have agreed to adopt resolutions, in form and substance reasonably acceptable to Ventas, and to take (or cause to be taken) all other actions reasonably determined by Ventas to be necessary or appropriate to terminate, effective immediately at least one day prior to the closing of the Mergers, any Company Benefit Plan intended to be qualified under Section 401(a) of the Internal Revenue Code and containing a cash or deferred arrangement under Section 401(k) of the Internal Revenue Code. The Company, the Operating

Table of Contents

Partnership and any other subsidiary of the Company have agreed to take such other actions in furtherance of the termination of each such Company Benefit Plan as Ventas may reasonably request, including such actions as Ventas may require prior to the effective time of the Company Merger to support Ventas obtaining a determination letter with respect to the termination of each such Company Benefit Plan following the closing of the Mergers.

Prior to the effective time of the Company Merger, the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership have agreed to adopt such resolutions and to take such other actions as are necessary and sufficient to provide that, subject to the requirements of applicable law, the current or former trustees, directors, officers, or employees of the Erdman Companies (or any dependent or beneficiary thereof) shall not be eligible to participate in the Company Benefit Plans (other than any Company Benefit Plan that covers only employees of the Erdman Companies) on or after the consummation of the Mergers. The Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership have also agreed to take such other actions in furtherance of the foregoing as Ventas may reasonably request. Furthermore, the Company, its subsidiaries (other than the Erdman Companies) and the Operating Partnership have agreed to cooperate in mutual good faith with Ventas to effectuate the transition of employees and Company Benefit Plans as mutually agreed upon between such parties.

•: no statute, rule, regulation, executive order, decree, ruling, judgment, decision, order or injunction shall have been enacted, entered, promulgated or enforced by any court or other governmental entity of competent jurisdiction which has the effect of making the Mergers or the other transactions contemplated by the merger agreement illegal or otherwise restraining or prohibiting the consummation of the Mergers.

•: Ventas terminates the merger agreement in the event Ventas is ready, willing and able to consummate the Mergers, and the closing does not occur within two business days after the first date all of the conditions to the Company's obligations to consummate the Mergers are satisfied or waived, and during that two business day period, the net debt closing condition is not satisfied.

Ventas is required to pay to us a termination fee equal to $15.0 million and an expense reimbursement equal to $5.0 million, if:

•: we terminate the merger agreement as a result of a breach of a representation, warranty, covenant or agreement made by Ventas, MergerSub or OP MergerSub in the merger agreement, which breach would give rise to the failure of the conditions precedent to the obligations of the Company and the Operating Partnership to consummate the Mergers to be satisfied and such breach is not cured within 15 days after notice thereof and materially contributed to the failure of the closing of the Mergers to have occurred; or
•: we terminate the merger agreement in the event the conditions to the obligations of Ventas, MergerSub and OP MergerSub to consummate the Mergers have been satisfied (other than those conditions that by their nature are to be satisfied by actions taken at the closing of the Mergers), and Ventas fails to consummate the transactions contemplated by the merger agreement within six business days following the date on which the closing of the Mergers should have occurred under the merger agreement and we stood ready, willing and able to consummate the Mergers on that date (subject to Ventas's right under the merger agreement to extend the date on which the closing should have occurred).

Table of Contents

In this proxy statement we refer to any acquisition proposal, but replacing references to "25% or more" in the definition of acquisition proposal with "more than 50%" and excluding any transaction solely in which equity securities are issued by the Company for cash in a bona fide capital raising transaction, as an alternative transaction.

Expenses

All costs and expenses incurred in connection with the merger agreement, the Mergers and the other transactions contemplated by the merger agreement will be paid by the party incurring such expense, except to the extent required by any applicable termination provision.

Remedies

In addition to the termination fees and expense reimbursements described under "The Merger Agreement—Termination Fees" beginning on page 79, the parties are entitled to specific performance of the terms of the merger agreement, including the right of the parties to cause the Mergers to be consummated on the terms set forth in the merger agreement, in addition to any other remedy at law or equity or pursuant to the merger agreement to which the parties may be entitled. Except as otherwise provided in the merger agreement, all remedies available under the agreement, at law or otherwise, shall be deemed cumulative and not alternative or exclusive of other remedies. The exercise by any party of a particular remedy shall not preclude the exercise of any other remedy.

Indemnification; Directors' and Officers' Insurance

From and after the effective time of the Company Merger, Ventas, the Surviving Company and applicable subsidiaries of the Company will exculpate, indemnify and hold harmless (and Ventas will advance expenses to) our present and former officers and directors pursuant to the MGCL (in the case of the Company), the Company's organizational documents, the organizational documents and governing law of any such subsidiary of the Company or any written agreement between any such person and the Company or any such Company subsidiary in effect on the date of the merger agreement, for acts or omissions occurring prior to the effective time of the Company Merger (including in connection with the merger agreement or the transactions contemplated thereby) to the fullest extent permitted by law and such rights will continue in full force and effect until 180 days after the expiration of the longest applicable statute of limitations with respect to any claims against such directors or officers arising out of such acts or omissions. Ventas also agrees that, from and after the effective time of the Company Merger, it shall honor and perform all obligations of the Company and each Company subsidiary in respect of such rights to exculpation and indemnification and advancement of expenses, including by paying or otherwise making available all requisite funds in a timely manner.

For a period of not less than six years after the effective time of the Company Merger, Ventas will, or will cause the Surviving Company to, maintain in effect our current directors' and officers' liability insurance covering each person currently covered by our directors' and officers' liability insurance policy; provided that Ventas or the Surviving Company may substitute a "tail" insurance policy with respect to the currently existing officers' and directors' liability insurance policy. Such "tail" insurance policy must be obtained from an insurance carrier with the same or better credit rating as our insurance carrier and the material terms, including coverage and amount, must be no less favorable in any material respect to the insureds as our existing policies. This obligation is subject to a cap of 225% of the annual premium amount we are currently paying for such insurance.

Our present and former directors and officers will have the right to enforce the provisions of the merger agreement relating to their indemnification and are express third party beneficiaries of the merger agreement solely for this purpose.

Access

Subject to certain exceptions, we will, upon reasonable prior written notice, afford Ventas and its authorized representatives reasonable access to the Company and furnish Ventas information concerning our business, properties and personnel as may reasonably be requested.

Modification or Amendment

At any time prior to the effective time of the Company Merger, the merger agreement may be amended, modified or supplemented by action authorized by the respective boards of directors of Ventas and the Company, whether before or after the stockholder approval has been obtained. However, if our stockholders have approved the Company Merger, no amendment shall be made to (i) change the amount or kind of consideration to be received by the holders of Company common stock upon conversion of their shares pursuant to the terms of the merger agreement; or (ii) change any of the other terms or conditions of the merger agreement if the change (A) would adversely affect the holders of Company common stock or OP Units in any material respect or (B) that pursuant to applicable law, requires further approval by the stockholders of the Company without such further approval.

SALE OF THE ERDMAN BUSINESS

Simultaneously with the execution of the merger agreement, the Company's subsidiary, Cogdell Spencer TRS Holdings, LLC, which we refer to as TRS Holdings, entered into a stock purchase agreement with Madison DB Acquisition, LLC, which we refer to as Madison DB, pursuant to which Madison DB will acquire all of the shares of MEA Holdings, Inc., which we refer to as MEA and which, together with its subsidiaries, engage in design-build and related advisory services under the Marshall Erdman name, which we refer to collectively as the Erdman business. We refer to MEA's subsidiaries, Erdman Company, Erdman Architecture and Engineering Company, Marshall Erdman Development, LLC, and Erdman Purchasing Group, LLC as the Erdman subsidiaries, and together with MEA, the Erdman Companies. We refer to the stock purchase agreement, dated as of December 24, 2011, among Madison DB, TRS Holdings, and the Company as guarantor, as the Erdman purchase agreement. The Company has guaranteed the performance of TRS Holdings' obligations under the Erdman purchase agreement and has agreed to be bound by its terms. We refer to the transactions contemplated by the Erdman purchase agreement as the Erdman Sale. Consummation of the Erdman Sale is subject to customary closing conditions, including satisfaction of the conditions to closing of the transactions contemplated by the merger agreement (other than those conditions which, by their nature, are to be satisfied at the closing of the transactions contemplated by the merger agreement).

Set forth below are material terms and conditions of the Erdman Sale as set forth in the Erdman purchase agreement. The following description of the Erdman purchase agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Erdman purchase agreement, which has been filed with the Company's SEC reports and incorporated herein by reference. See "Where You Can Find More Information" beginning on page 89. In the event the Company receives a superior proposal for the Erdman Companies and elects to terminate the Erdman purchase agreement to accept such superior proposal in accordance with the terms of the Erdman purchase agreement, the Company expects the new purchaser to enter into a replacement agreement on terms that are not more favorable to the prospective buyer, in the aggregate, than the terms included in the Erdman purchase agreement.

Purchase Price and Closing

At closing, Madison DB will pay $1.00 to TRS Holdings and will contribute a net amount of $10,620,000 in working capital to MEA. TRS Holdings will, prior to closing, contribute $11,720,000 (subject to certain adjustments) to MEA and, prior to closing, will extinguish certain intercompany indebtedness of MEA.

Representations and Warranties

TRS Holdings and Madison DB made certain representations and warranties in the Erdman purchase agreement that are subject, in some cases, to specified exceptions and qualifications contained in the Erdman purchase agreement and the matters contained in the disclosure schedule delivered by TRS Holdings in connection with the Erdman purchase agreement. Among other things, Madison DB acknowledged that it is acquiring the Erdman Companies on an "as-is, where-is" basis.

Table of Contents

Conduct of Business Before Closing

From December 24, 2011 to the closing of the Erdman Sale, TRS Holdings has agreed to cause MEA and each of the Erdman subsidiaries to (i) use commercially reasonable efforts to preserve intact its present business organization and goodwill, and to keep available the services of its officers and key employees, (ii) comply with the requirements of all applicable laws, and (iii) maintain certain insurance coverage consistent with past practice. In addition, except with the prior written consent of Madison DB, from December 24, 2011 until the closing of the Erdman Sale, TRS Holdings has also agreed not to take (and shall cause MEA and each of the Erdman subsidiaries not to take) certain actions specified in the Erdman purchase agreement.

If the merger agreement is amended or modified in any manner that materially and adversely affects Madison DB's rights under the Erdman purchase agreement or Madison DB's or TRS Holdings' ability to consummate the transactions contemplated by the Erdman purchase agreement, then Madison DB may terminate the Erdman purchase agreement in accordance with certain procedures. These procedures require Madison DB to first give written notice to TRS Holdings stating its intent to terminate and specifying in reasonable detail its reasons and to allow ten business days following the delivery of such notice for TRS Holdings to address the issues raised. If the Erdman purchase agreement is terminated based on a modification or amendment of the merger agreement in accordance with these procedures, then TRS Holdings must pay Madison DB a termination fee of $400,000 within five business days of the termination.

Go-Shop Period

Except as described below, the stockholders of the Company will not receive any consideration from the sale of the Erdman Companies pursuant to the Erdman purchase agreement distinct from the consideration received pursuant to the merger agreement. Under the Erdman purchase agreement, during the period beginning on December 24, 2011 and continuing until 12:01 a.m. (EST) on February 10, 2012, which we refer to as the go-shop period, TRS Holdings, MEA or the Erdman subsidiaries may initiate, solicit and encourage any alternative acquisition proposals from third parties, provide non-public information and participate in discussions and negotiate with third parties with respect to alternative proposals to acquire the Erdman Companies, and terminate the Erdman purchase agreement in order to enter into a substitute purchase agreement to sell the Erdman Companies to a third party which must contain terms and conditions that are not more favorable, in the aggregate, to the prospective buyer of the Erdman business. In the event TRS Holdings enters into a substitute purchase agreement, it must pay to Madison DB a termination fee of $400,000 and, pursuant to the terms of the merger agreement, the Company and the Operating Partnership would, prior to consummation of the Mergers, distribute to the holders of the Company common stock and the OP Units and LTIP Units, respectively, an amount in cash equal to the net proceeds (after deduction of the $400,000 termination fee and any incremental expenses associated with the go-shop process) from the sale of the Erdman Companies pursuant to the substitute purchase agreement.

The Company, with the assistance of its financial advisor, began actively soliciting indications of interest from third parties regarding a possible acquisition of the Erdman business in early January 2012.

Non-Solicit

TRS Holdings has agreed that, prior to the closing of the Erdman Sale and for a period of 12 months after the closing, neither it nor its affiliates will contact, solicit or entice, or attempt to contact, solicit or entice, any person so as to cause, or attempt to cause, such person not to do business with MEA or any Erdman subsidiary with respect to certain scheduled development projects that are set forth on a schedule attached to the Erdman purchase agreement.

Conditions to Closing

Consummation of the transactions contemplated by the Erdman purchase agreement is subject to customary closing conditions, including satisfaction or waiver of all conditions to closing of the Mergers (other than those conditions which, by their nature, are to be satisfied at the closing of the Mergers).

ADVISORY VOTE REGARDING GOLDEN PARACHUTE COMPENSATION

In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which we refer to as the Dodd-Frank Act, and pursuant to Section 14A of the Exchange Act, we are providing our common stockholders with an opportunity to cast a non-binding advisory vote to approve the "golden parachute" compensation that certain executive officers of the Company will or may receive in connection with the Company Merger. Under the Dodd-Frank Act and for this purpose, "golden parachute" compensation is any type of compensation, whether present, deferred or contingent, that is based on or otherwise relates to the Company Merger pursuant to arrangements entered into with the Company and as disclosed in this proxy statement. Accordingly, we are asking our common stockholders to approve the following non-binding resolution at the special meeting:

"RESOLVED, that the stockholders of Cogdell Spencer Inc. approve, on a non-binding advisory basis, the "golden parachute" compensation based on or otherwise related to the Company Merger that the Company's named executive officers will or may receive in connection with the Company Merger as disclosed pursuant to Item 402(t) of Regulation S-K in the section titled "The Company Merger—Interests of the Company's Directors and Executive Officers in the Company Merger—Golden Parachute Compensation."

Vote Required and Board of Director Recommendation

The vote on this proposal is a vote separate and apart from the vote to approve the Company Merger. Accordingly, you may vote not to approve this proposal on "golden parachute" compensation that certain executive officers of the Company will or may receive in connection with the Company Merger and vote to approve the Company Merger and vice versa.

This resolution, commonly referred to as a "say-on-golden-parachute" resolution, requires the affirmative vote of a majority of the votes cast by our common stockholders at a duly called meeting and at which a quorum is present. For purposes of this proposal, (i) abstentions will not be counted in tabulating the votes cast, and will not have an effect on the proposal, (ii) broker non-votes will not be counted in tabulating the votes cast, and will not have an effect on the proposal and (iii) if you fail to submit a proxy or vote in person at the special meeting, the shares of Company common stock not voted will not be counted in respect of, and will not have an effect on, the proposal.

Because the vote is advisory in nature only, it will not be binding on either the Company or Ventas regardless of whether the Company Merger is completed. Approval of this proposal on "golden parachute" compensation that certain executive officers of the Company will or may receive in connection with the Company Merger is not a condition to completion of the Company Merger, and failure to approve this advisory matter will have no effect on the vote to approve the Company Merger. Because the compensation to be paid in connection with the Company Merger is based on contractual arrangements with the named executive officers, regardless of the outcome of this advisory vote, such compensation will be payable, subject only to the contractual conditions applicable thereto, if the Company Merger is completed.

The board of directors recommends that you vote "FOR" the proposal to approve, on a non-binding basis, the "golden parachute" compensation that the Company's named executive officers will or may receive in connection with the Company Merger.

BACKGROUND

WHEREAS, the parties wish to provide for a business combination transaction in which, upon the terms and subject to the conditions set forth in this Agreement, (i) the Company would effect a merger pursuant to which either (A) MergerSub will be merged with and into the Company, with the Company surviving as a wholly-owned subsidiary of Parent, or (B) the Company will be merged with and into MergerSub, with MergerSub surviving as a wholly-owned subsidiary of Parent, and (ii) OP MergerSub will be merged with and into the Operating Partnership, with the Operating Partnership surviving as a wholly-owned subsidiary of Parent; and

WHEREAS, the respective boards of directors of the Company, Parent and MergerSub each have adopted resolutions declaring that the Merger and the other transactions provided for in this Agreement are advisable on the terms and conditions set forth in this Agreement, as well as approving such Merger and other transactions; and

WHEREAS, the general partner of the Operating Partnership and the sole member of OP MergerSub each have approved the Partnership Merger and the other transactions contemplated by this Agreement; and

WHEREAS, concurrently with the execution of this Agreement, the Erdman Seller, the Erdman Purchaser and the Company entered into the Erdman Purchase Agreement, pursuant to which, prior to the Closing, the Erdman Sale will be consummated;

NOW, THEREFORE, the parties hereto, intending to be legally bound, agree as follows:

As used in this Agreement, (A) "Merger" shall refer to either of the mergers described in the immediately preceding sentence, and (B) "Surviving Company" shall refer to the Company or MergerSub, as the case may be, as the surviving entity of the Merger. The Merger shall have the effects set forth in this Agreement and the applicable provisions of the MGCL, including Section 3-114. Without limiting the generality of the foregoing, at the Effective Time, except as otherwise provided in this Agreement, all the property, rights, privileges, powers and franchises, and all and every other interest of MergerSub and the Company, shall vest in the Surviving Company, and all debts, liabilities and duties of MergerSub and the Company shall become the debts, liabilities and duties of the Surviving Company.

Section 1.8. Tax Treatment. In the event that a Reverse Triangular Merger is consummated, the parties hereto (a) intend that for federal, and applicable state and local, income tax purposes, the Mergers will be treated as a taxable purchase by Parent of all of the outstanding shares of Company Common Stock, Series A Preferred Stock and OP Units, the latter of which shall be treated as a sale of OP Units by each transferor of such OP Units and an acquisition of the assets of the Operating Partnership by the Parent as transferee of such OP Units and (b) shall prepare and file their applicable Tax Returns based on such treatment. In the event that Forward Triangular Merger is consummated, the parties hereto (i) intend that for federal, and applicable state and local, income tax purposes, the Mergers will be treated as (A) a taxable disposition by the Company of all of its assets to MergerSub in exchange for the Per Share Consideration and the Per Share Preferred Consideration, and the assumption of all of the Company's liabilities, followed by a liquidating distribution of such Per Share Consideration and Per Share Preferred Consideration to the holders of the Company Common Stock and Series A Preferred Stock, pursuant to Section 331 and Section 562 of the Code, and (B) a taxable purchase by Parent of all of the OP Units, which shall be treated as a sale of OP Units by each transferor of such OP Units and an acquisition of the assets of the Operating Partnership by the Parent and (ii) shall prepare and file their applicable Tax Returns based on such treatment.

The cash deposited with the Paying Agent pursuant to thisSection 2.4(a) shall hereinafter be referred to as the "Payment Fund." The Payment Fund shall not be used for any purpose other than to fund payments due pursuant toSections 2.1(a),2.1(d),2.2(a), or2.6, except as provided in this Agreement.

(b) Not later than the fifth Business Day following the Effective Time, Parent shall cause the Paying Agent to mail to each holder of record of outstanding shares of Company Common Stock or Series A Preferred Stock immediately prior to the Effective Time, whether represented by stock certificates (the "Company Certificates") or in book entry form, whose shares were converted into the right to receive the Per Share Consideration pursuant toSection 2.1(a) or the Per Share Preferred Consideration pursuant toSection 2.1(d), (i) a letter of transmittal in customary form (which shall specify the number of shares of Company Common Stock or Company Preferred Stock held by such holder and shall be in customary form), and (ii) instructions for use in effecting the surrender of the shares of Company Common Stock or the Company Preferred Stock in exchange for the Per Share Consideration or Per Share Preferred Consideration, as applicable. Upon delivery to the Paying Agent of such letter of transmittal, properly completed and duly executed, any Company Certificate representing the shares held by such holder and such other documents specified in the instructions for use referred to above as the Paying Agent or Parent reasonably shall require, the shares of Company Common Stock or Company Preferred Stock described therein shall be deemed surrendered for cancellation and payment and the holder identified in such letter shall be entitled promptly to receive in exchange therefor, and Parent shall cause the Paying Agent to promptly pay, the Per Share Consideration or Per Share Preferred Consideration, as applicable, and the shares so surrendered shall be cancelled. If a transfer of ownership of shares of Company Common Stock or Series A Preferred Stock has occurred but has not been registered in the transfer records of the Company, the Per Share Consideration or Per Share Preferred Consideration applicable to those shares may be paid to the transferee if the letter of transmittal is delivered in accordance with thisSection 2.4(b), along with any Company Certificates representing such shares of Company Common Stock or Series A Preferred Stock, as applicable, and all documents and endorsements required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. If any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Company Certificate to be lost, stolen or destroyed (which affidavit shall be in form

A-5

and substance reasonably acceptable to Parent), the Paying Agent shall pay in exchange for the shares represented by such lost, stolen or destroyed Company Certificate the Per Share Consideration or Per Share Preferred Consideration applicable to the shares of Company Common Stock or Series A Preferred Stock, as applicable, represented by such Company Certificate deliverable in respect thereof determined in accordance with thisArticle II;provided, that Parent or the Paying Agent may, in its discretion, require the delivery of a reasonable indemnity or bond against any claim that may be made against the Surviving Company with respect to such Company Certificate or ownership thereof.

(d) The Operating Partnership and each other Company Subsidiary that is a partnership, joint venture, or limited liability company and which has not elected to be a "taxable REIT subsidiary" within the meaning of Section 856(l) of the Code has been since its formation treated for U.S. federal income tax purposes as a partnership or disregarded entity, as the case may be, and not as a corporation or an association taxable as a corporation.

(i) None of the Company, the Operating Partnership or any other Company Subsidiary (i) is or has ever been a member of an affiliated group (other than a group the common parent of

A-27

which is a directly or indirectly wholly-owned subsidiary of the Company or the Operating Partnership) filing a consolidated federal income tax return, and (ii) has any liability for the Taxes of another Person other than the Company, the Operating Partnership and the other Company Subsidiaries under Treasury Regulation 1.1502-6 (or any similar provision of state, local or foreign Law), as a transferee or successor or by contract.

True, correct and complete copies of all such Tax Protection Agreements have been made available to Parent. As used herein, "Tax Protection Agreements" means any written agreement to which the Company, the Operating Partnership or any other Company Subsidiary is a party pursuant to which: (i) any liability to holders of OP Units relating to Taxes may arise, whether or not as a result of the consummation of the transactions contemplated by this Agreement; (ii) in connection with the deferral of income Taxes of a holder of OP Units, the Company, the Operating Partnership or the other Company Subsidiaries have agreed to (A) maintain a minimum level of Indebtedness or continue any particular Indebtedness, (B) retain or not dispose of assets for a period of time that has not since expired, (C) make or refrain from making Tax elections, and/or (D) only dispose of assets in a particular manner; and/or (iii) limited partners of the Operating Partnership have guaranteed Indebtedness of the Operating Partnership.

The Company, the Operating Partnership and the other Company Subsidiaries have not participated in any transaction that could give rise to a disclosure obligation as a "listed transaction" under Section 6011 of the Code and the regulations thereunder or any similar provision under applicable Laws.

(n) ThisSection 3.17 contains the exclusive representations and warranties of the Company and the Operating Partnership with respect to Tax matters.

Section 3.18. Insurance. The Company has made available to Parent copies of all insurance policies and all fidelity bonds or other insurance service contracts in effect at the date of this Agreement (the "Insurance Policies") in the Company's or any Company Subsidiary's possession providing coverage for any or all Company Properties or that are otherwise material to the operations of the Company and the Company Subsidiaries, taken as a whole. Except for those matters that have not had and would not reasonably be expected to have a Company Material Adverse Effect, at the date of this Agreement, there is no claim for coverage by the Company, the Operating Partnership or any other Company Subsidiary pending under any of the Insurance Policies that has been denied or disputed by the insurer.

The parties shall use their respective reasonable best efforts to resist, contest or defend any suit, claim, action or proceeding (including administrative or judicial actions and proceedings) challenging the Mergers or the completion of the transactions contemplated hereby. Subject to applicable Law and the instructions of any Governmental Entity, the Company and Parent shall keep each other reasonably apprised of the status of matters relating to the completion of the transactions contemplated hereby, including promptly furnishing the other with copies of notices or other written communications received by the Company or Parent, as the case may be, or any of their respective subsidiaries, from any Governmental Entity and/or third party with respect to such transactions, and, to the extent practicable under the circumstances, shall provide the other party and its counsel with the opportunity to participate in any meeting with any Governmental Entity in respect of any filing, investigation or other inquiry in connection with the transactions contemplated hereby.

Section 5.3. Preparation of Proxy Statement.

(a) As promptly as practicable, and in no event later than twenty (20) Business Days following the date of this Agreement, the Company shall prepare and file the Proxy Statement with the SEC. The Company shall use its reasonable best efforts to have the Proxy Statement cleared by the SEC as promptly as practicable.

(b) The Company will advise Parent, as promptly as practicable after it receives notice hereof, of any request by the SEC to amend the Proxy Statement or comments thereon and responses thereto or requests by the SEC for additional information. If, at any time before the Effective Time, either Parent or the Company discovers or determines that any information relating to that party or its Affiliates should be set forth in an amendment or supplement to the Proxy Statement in order to comply with applicable Law or in order that any such document would not include any material misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not material, the

A-38

party making that discovery or determination shall notify the other and, to the extent required by Law, the parties shall cause an appropriate amendment or supplement addressing such information to be promptly filed with the SEC and, to the extent required by Law, disseminated to the stockholders of the Company. All filings by the Company with the SEC in connection with the transactions contemplated hereby, including the Proxy Statement and any amendment or supplement thereto and all mailings to the Company's stockholders in connection with the Merger and transactions contemplated by this Agreement shall be subject to the reasonable prior review and comment of Parent.

At the Company Stockholders Meeting, Parent shall cause all shares of Company Common Stock then owned by Parent or any of the Parent Subsidiaries to be voted in favor of the approval and adoption of this Agreement and the Merger. At any time before the Company Stockholder Approval has been obtained, the Company's Board of Directors may make an Adverse Recommendation Change only if the Company's Board of Directors determines in good faith, after taking into account the advice of the Company's outside legal counsel, that the failure to withdraw or modify the Recommendation would be reasonably likely to constitute a breach of the duties of the Company's directors to the Company's stockholders under applicable Law. The Company shall not be required to hold the Company Stockholders Meeting if this Agreement is validly terminated before the meeting is held.

Section 5.5. Public Statements. Each of the Company, Parent and MergerSub agrees that no public release or announcement concerning the transactions contemplated hereby shall be issued by any party without the prior written consent of the Company and Parent (which consent shall not be unreasonably withheld, conditioned or delayed), except as such release or announcement may be required by applicable Law or any applicable rules or regulations of any United States securities exchange, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow each other party reasonable time to comment on such release or announcement in advance of such issuance, it being understood that the final form and content of any such release or announcement, to the extent so required, shall be at the final discretion of the disclosing party; provided, however, that upon prior consultation with the other party, each of the parties may make statements that are not inconsistent with previous press releases, public disclosures or public statements made by any of the parties in compliance with thisSection 5.5.

A-39

Company, the Operating Partnership or any Company Subsidiary during such period pursuant to the requirements of federal or state securities Laws, and (ii) all other information (financial or otherwise) concerning its business, properties and personnel as Parent may reasonably request. Notwithstanding the foregoing, no Person shall be required by thisSection 5.6 to provide Parent or its Representatives with (x) access to physical properties for the purpose of invasive physical testing, or (y) any information that the Company reasonably believes may not be provided to Parent by reason of applicable Law which constitutes information protected by attorney/client privilege, or which the Company or any Company Subsidiary is required to keep confidential by reason of contract, agreement or understanding with third parties (it being understood that the Company shall, and shall cause each relevant Company Subsidiary to, use its reasonable best efforts to obtain any and all consents of such third parties as shall be necessary to permit such information to be disclosed to Parent and its Representatives. Neither Parent nor its Representatives, in the exercise of the rights described in thisSection 5.6, shall unduly interfere with the operation of the business of the Company or any Company Subsidiary. No investigation pursuant to thisSection 5.6 or information provided, made available or delivered to Parent pursuant to thisSection 5.6 or otherwise shall affect any representations or warranties of the Company or conditions or rights of Parent contained in this Agreement.

(b) Each of the Purchaser Parties will hold, and will cause its respective Representatives to hold, any non-public information in confidence to the extent required by, and in accordance with, and will otherwise comply with the terms of the letter agreement between the Company and Parent dated as of November 18, 2011 (as amended, through the date hereof, and as further amended from time to time, the "Confidentiality Agreement").

Section 5.8. Acquisition Proposals.

(a) As used in this Agreement:

"Acquisition Proposal" means any proposal or offer, whether in one transaction or a series of related transactions (i) for a merger, consolidation, share or equity interest exchange, dissolution, recapitalization or other business combination to which the Company, the Operating Partnership or any Company Subsidiary that would constitute a "significant subsidiary" (as defined in Rule 1-02 of Regulation S-X, but substituting 25% for references to 10% therein) is a constituent party, (ii) for the issuance, sale or other disposition by the Company or any Company Subsidiary (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase, or securities convertible into, such securities) representing 25% or more of the outstanding voting interests in the Company, the Operating Partnership or any Company Subsidiary, (iii) for the

A-40

sale or other disposition, directly or indirectly, by merger, consolidation, share exchange or any similar transaction, of any assets (including equity securities of any Company Subsidiary) of the Company, the Operating Partnership or the Company Subsidiaries representing 25% or more of the consolidated assets of the Company and the Company Subsidiaries, (iv) tender offer or exchange offer in which any Person or "group" (as such term is defined under the Exchange Act) offers to acquire beneficial ownership, or the right to acquire beneficial ownership, of 25% or more of the outstanding shares of Company Common Stock or (v) transaction which is similar in form, substance or purpose to any of the foregoing transactions, in each case other than the transactions contemplated by this Agreement or the Erdman Purchase Agreement; and

"Superior Proposal" means any bona fide unsolicited written Acquisition Proposal (but replacing references to "25% or more" in the definition of Acquisition Proposal with "more than 50%") received after the date of this Agreement that is made by a third party (and not obtained in breach of this Agreement, including thisSection 5.8) on terms that the Company's Board of Directors determines in good faith after consultation with the Company's outside counsel and financial advisor to be more favorable to the stockholders of the Company than the Merger taking into account all the terms and conditions of such proposal and this Agreement (including any proposal by Parent to amend the terms of this Agreement, and including in each case the risks, probabilities and timing of consummation) and which the Company's Board of Directors determines in good faith is reasonably likely to be consummated and for which financing, if a transaction involving cash consideration (whether in whole or in part), is then fully committed or reasonably determined to be available by the Company's Board of Directors and which is not subject to any condition to consummation based on the availability of financing.

(b) (i) Subject to the other provisions of thisSection 5.8, until the Effective Time or, if earlier, the termination of this Agreement in accordance withArticle VII, none of the Company, the Operating Partnership, or the other Company Subsidiaries shall, and they shall use reasonable best efforts to cause their respective officers, directors, employees, consultants, agents, advisors and other representatives not to, directly or indirectly, (i) initiate, solicit, knowingly facilitate or encourage (including by way of providing non-public information) the submission of any Acquisition Proposal or any inquiries, proposals or offers that reasonably may be expected to lead to, any Acquisition Proposal or engage in any discussions or negotiations with respect thereto or otherwise cooperate with or assist or participate in, or facilitate any such inquiries, proposals, discussions or negotiations, or (ii) approve, adopt or recommend, or propose to approve, adopt or recommend, an Acquisition Proposal or enter into any merger agreement, letter of intent, agreement in principle, share purchase agreement, asset purchase agreement or share exchange agreement, option agreement or other similar agreement providing for or relating to an Acquisition Proposal, or enter into any agreement or agreement in principle requiring the Company or the Operating Partnership to abandon, terminate or fail to consummate the Mergers or breach its obligations hereunder, or propose or agree to do any of the foregoing.

The Company and the Operating Partnership shall, and shall direct each Company Subsidiary and each agent or representative of any of the foregoing to, (A) immediately cease any discussions, negotiations, or communications with any party with respect to any Acquisition Proposal, and (B) promptly request

A-41

that all Persons with which the Company or its Representatives have had discussions or negotiations regarding any Acquisition Proposal within 12 months prior to the date of this Agreement return to the Company or destroy all copies of confidential information previously provided to such Persons by the Company, the Company Subsidiaries, or any Representatives thereof.

(c) Notwithstanding anything to the contrary contained in this Agreement, until the Company Stockholder Approval is obtained, if the Company has received from a third party an unsolicited written Acquisition Proposal that did not result from a breach of thisSection 5.8 and that the Company's Board of Directors determines in good faith (after consultation with the Company's outside counsel and financial advisor) constitutes or is reasonably likely to lead to a Superior Proposal, then the Company may (A) furnish information with respect to the Company, the Operating Partnership and the other Company Subsidiaries to the Person making the Acquisition Proposal (pursuant to a customary confidentiality agreement substantially similar to and not less favorable to the Company, in the aggregate, than the Confidentiality Agreement, it being understood that such confidentiality agreement need not prohibit the submission of Acquisition Proposals or amendments thereto to the Company in accordance with thisSection 5.8); and (B) participate in discussions or negotiations with such Person regarding the Acquisition Proposal; provided, that the Company shall (x) promptly notify Parent (within twenty-four (24) hours) in writing (1) of any such determination by the Company's Board of Directors that such Acquisition Proposal constitutes or is reasonably likely to constitute a Superior Proposal and that failure to take such action would be reasonably likely to lead to a breach of the duties of the Company's directors to the Company's stockholders under applicable Law (2) of any such furnishing of information, and (y) provide to Parent any non-public information concerning the Company, the Operating Partnership or any other Company Subsidiary that is provided to any Person pursuant to thisSection 5.8(c) and was not previously provided to Parent promptly following any delivery of such information to such Person. Any public disclosure or announcement by the Company relating to an Acquisition Proposal shall be deemed to be an Adverse Recommendation Change by the Company, unless the Board of Directors of the Company affirms that it is not modifying or changing in a manner adverse to Parent its approval or recommendation of this Agreement and the Merger in such disclosure.

(d) The Company promptly shall (and in no event less than twenty-four (24) hours following the Company's initial receipt of any Acquisition Proposal) notify Parent of its receipt of any Acquisition Proposal and shall, in any such notice to Parent, indicate the identity of the Person making such Acquisition Proposal and the material terms and conditions of any such Acquisition Proposal. In addition, the Company shall promptly (but in any event within twenty-four (24) hours after the receipt thereof) provide to Parent copies of any written documentation material to understanding such Acquisition Proposal ("Other Acquisition Documentation") which is received by the Company from the Person (or from any representatives or agents of such Person) making such Acquisition Proposal. The Company shall not, and shall cause each of its Subsidiaries not to, take any action to exempt any Person from the restrictions on "business combinations" contained in any applicable Laws or to otherwise cause such restrictions not to apply, or terminate, waive, amend or modify any provision of any existing confidentiality to which it or any Company Subsidiary is a party, and the Company shall use reasonable best efforts to, and shall cause the Company Subsidiaries, to use reasonable best efforts to, enforce the provisions of any such agreement (provided that, notwithstanding the foregoing, the Company shall not be required to take, or be prohibited from taking, any action otherwise prohibited by this sentence if and only, the Board of Directors of the Company has determined in good faith, after considering the advice of outside legal counsel, that taking such or action or failing to take such action, as the case may be, would be reasonably likely to result in a breach of the duties of the Company's directors to the Company's stockholders under applicable Law). The Company shall provide to Parent within

A-42

twenty-four (24) hours after receipt thereof all copies of any additional Other Acquisition Documentation received by the Company from the Person (or from any representatives or agents of such Person) making such Acquisition Proposal. The Board of Directors of the Company shall promptly consider in good faith (in consultation with its outside legal counsel and financial advisors) any proposed alteration of the terms of this Agreement or the Merger proposed by Parent in response to any Acquisition Proposal. Thereafter, the Company shall keep Parent reasonably informed on a current basis of the status of and material terms and conditions (including any changes to the material terms and conditions) of any such Acquisition Proposal.

(e) Notwithstanding anything to the contrary in this Agreement, if, at any time before obtaining the Company Stockholder Approval, the Company receives an unsolicited written Acquisition Proposal that did not result from a breach of thisSection 5.8 and that the Company's Board of Directors determines in good faith (after consultation with the Company's outside counsel and financial advisor) constitutes a Superior Proposal, the Company may terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal if its Board of Directors determines in good faith, after consultation with outside counsel, that failure to take such action would be reasonably likely to constitute a breach of the duties of the Company's directors to the Company's stockholders under applicable Law;provided, that concurrently with such termination the Company pays the Termination Fee payable pursuant toSection 7.2(b) (but subject to the provisions ofSection 7.2(e)); andprovided, further, that the Company may not terminate this Agreement pursuant to thisSection 5.8(e) unless the Company shall have provided prior written notice (a "Termination Notice") to Parent, at least three (3) Business Days in advance of taking such action (the "Notice Period"), of its intention to terminate this Agreement to enter into a definitive agreement with respect to such Superior Proposal, which notice shall specify the material terms and conditions of the Superior Proposal (including the identity of the party making the Superior Proposal), and shall be accompanied by a copy of a draft of the definitive agreement proposed to be entered into with respect to the Superior Proposal, and (ii) during the Notice Period, the Company shall negotiate in good faith with Parent (to the extent Parent desires to do so) to make such adjustments to the terms and conditions of this Agreement such that such Acquisition Proposal would no longer constitute a Superior Proposal and provided further, however, that after the expiration of such three (3) Business Day period and prior to the termination of this Agreement pursuant to thisSection 5.8(e), the Company's Board of Directors shall have confirmed (after taking into account any such adjustments to the terms and conditions of this Agreement) that the Acquisition Proposal continues to be a Superior Proposal. In the event that during the Notice Period any revisions are made to the Superior Proposal and the Company's Board of Directors in its good faith judgment determines such revisions are material (it being agreed that any change in the purchase price in such Superior Proposal shall be deemed a material revision), the Company shall be required to deliver a new Termination Notice and to comply with the requirements of thisSection 5.8(e) with respect to such new Termination Notice.

(f) Nothing contained in this Agreement shall prohibit the Company from (i) taking and disclosing to the Company's stockholders a position contemplated by Rule 14e 2(a) promulgated under the Exchange Act, or (ii) making any other disclosure to the Company's stockholders if, in the case of any disclosure described in this clause (ii), the Company's Board of Directors determines in good faith, after consultation with outside counsel, that failure to make such disclosure would be reasonably likely to constitute a breach of the duties of the Company's directors to the Company's stockholders under applicable Law.

Section 5.10. Directors' and Officers' Exculpation, Indemnification and Insurance.

(a) Parent agrees that it shall, and shall cause the Surviving Company and the applicable Company Subsidiaries (other than any Erdman Company) to, assume and perform all rights to exculpation and indemnification in favor of, and all rights to advancement of expenses to, each Person who at the Effective Time is a current or former director or officer of the Company or any such Company Subsidiary, as such rights exist pursuant to the MGCL (in the case of the Company), the Company's Charter or Bylaws, the organizational documents and governing Law of any such Company Subsidiary or any written agreement between any such Person and the Company or any such Company Subsidiary in effect on the date of this Agreement, for acts or omissions occurring prior to the Effective Time (including acts or omissions occurring in connection with this Agreement and the consummation of the transactions contemplated hereby), and such rights shall continue in full force and effect until 180 days after the expiration of the longest applicable statute of limitation. Parent also agrees that, from and after the Effective Time, it shall (or shall cause the Surviving Company to) honor, and perform all obligations of, the Company and each Company Subsidiary in respect of all such rights to exculpation and indemnification and advancement of expenses, including by paying or otherwise making available (or causing to be paid or made available) all requisite funds in a timely manner.

(b) From and after the Effective Time, Parent shall (or shall cause the Surviving Company to) maintain in effect for not less than six years from the Effective Time the insurance coverage provided under the policies of directors' and officers' liability insurance maintained by the Company at the date of this Agreement, under the policies described inSection 5.10 of the Company Disclosure Schedule attached hereto; provided, that Parent or the Surviving Company may substitute therefor one or more policies issued by one or more carriers with an equal or greater credit rating from A.M. Best Company (or a comparable rating agency) as relevant carriers that are being replaced, which substitute policies shall provide at least the same coverage as that under the policies being replaced on terms and conditions which are no less advantageous to such Persons, but only if such substitution does not result in any lapses in coverage with respect to matters occurring prior to the Effective Time; and provided, further, that neither Parent nor the Surviving Company shall be required to pay an annual premium for such coverage in excess of 225% of the last annual premium paid by the Company prior to the date of this Agreement; and if Parent or the Surviving Company is unable to obtain the insurance required by thisSection 5.10, it shall obtain as much comparable insurance as possible for an annual premium equal to such maximum amount. Parent's obligations under this paragraph may be satisfied by the purchase of a "tail" insurance policy that provides the coverage described above.

Section 5.11. Employee Benefits.

(a) From and after the Effective Time, Parent shall honor, and cause the Surviving Company to honor, each Company Benefit Plan listed onSection 3.10(a) of the Company Disclosure Schedule that is not an Erdman Benefit Plan and any related funding arrangements of any such Company Benefit Plan in accordance with its terms. Without limiting the generality of the foregoing, Parent shall honor, and cause the Surviving Company to honor, all rights to vacation, personal and sick days accrued by employees of the Acquired Companies under the Company Benefit Plans and reflected in the records of the Company through and including the Effective Time. Until the date that is twelve (12) months after the Effective Time, Parent shall provide, and cause the Surviving Company to provide, pension, welfare and fringe benefits (other than incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) to the employees of the Acquired Companies that are in the aggregate no less favorable than the pension, welfare and fringe benefits (other than incentive compensation, equity-based compensation, defined benefit pension benefits and retiree medical benefits) that, at the election of Parent, are provided (x) to such employees pursuant to Company Benefit Plans on the date of

A-44

this Agreement or (y) by Parent to its similarly situated employees. Nothing herein shall require Parent to continue any particular Company Benefit Plan or prevent the Parent from terminating (or causing the termination of) the employment of any employee of the Acquired Companies at any time after the Closing Date for any reason (or no reason).

(b) With respect to any employee benefit plans in which any employees of the Acquired Companies first become eligible to participate on or after the Effective Time, and in which the employees of the Acquired Companies did not generally participate before the Effective Time, Parent shall, to the extent applicable: (i) waive all pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the employees of the Acquired Companies under any such new plans in which such employees may be eligible to participate after the Effective Time, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous Company Benefit Plan; (ii) provide each employee of the Acquired Companies with credit for any co-payments and deductibles paid during the calendar year in which the Effective Time occurs (to the same extent such credit was given under the analogous Company Benefit Plan before the Effective Time) in satisfying any applicable deductible or out-of-pocket requirements under any such new plan in which such employees may be eligible to participate after the Effective Time; (iii) recognize all service of such employees for all purposes (including purposes of eligibility to participate, vesting, entitlement to benefits and benefit accrual (other than under any defined benefit plan)) in any such new plan in which such employees may be eligible to participate after the Effective Time; and (iv) with respect to flexible spending accounts, provide each employee of the Acquired Companies with a credit for any salary reduction contributions made thereto and a debit for any expenses incurred thereunder with respect to the plan year in which the Effective Time occurs; provided, that the foregoing shall not require duplication of benefits.

(c) Prior to making any written or oral communications to the directors, officers or employees of the Company, the Operating Partnership or any other Company Subsidiary pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement, the Company shall provide Parent with a copy of the intended communication, and Parent shall have a reasonable period of time to review and comment on the communication, and Parent and the Company shall cooperate in providing any such mutually agreeable communication;provided, that the Erdman Companies shall not be required to provide to Parent for review any communications from any of the Erdman Companies to officers and employees of the Erdman Companies that relate solely to the compensation and benefits obligations of the Erdman Companies.

(d) If requested by Parent prior to the Effective Time, the Company, the Operating Partnership or a Company Subsidiary, as applicable, shall adopt resolutions, in form and substance reasonably acceptable to Parent, and take (or cause to be taken) all other actions reasonably determined by Parent to be necessary or appropriate to terminate, effective immediately at least one day prior to the Closing Date (the "ERISA Effective Date"), any Company Benefit Plan intended to be qualified under Section 401(a) of the Code and containing a cash or deferred arrangement under Section 401(k) of the Code (a "401(k) Plan"). Prior to the ERISA Effective Date, the Company shall provide Parent with executed copies of all resolutions authorizing such termination and amending any such 401(k) Plan commensurate with its termination to the extent necessary to comply with all applicable Laws. The Company, the Operating Partnership and the other Company Subsidiaries shall also take such other actions in furtherance of the termination of each 401(k) Plan as Parent may reasonably request, including such actions as Parent may require prior to the Effective Time to support Parent obtaining a determination letter with respect to the termination of each 401(k) Plan following the ERISA Effective Date.

A-45

(e) Prior to the Effective Time, the Acquired Companies shall adopt such resolutions and take such other actions as are necessary and sufficient to provide that, subject to the requirements of applicable Law, the current or former trustees, directors, officers, or employees of the Erdman Companies (or any dependent or beneficiary thereof) shall not be eligible to participate in the Company Benefit Plans (other than any Erdman Benefit Plan) on or after the Closing Date. Prior to the Effective Time, the Acquired Companies shall provide Parent with copies of all such resolutions. The Acquired Companies shall also take such other actions in furtherance of the foregoing as Parent may reasonably request. The Company, the Operating Partnership and any Company Subsidiary shall cooperate in mutual good faith with Parent to effectuate the transition of employees and Company Benefit Plans as mutually agreed upon between such parties.

(f) ThisSection 5.11 shall be binding upon and inure solely to the benefit of each of the parties to this Agreement, and nothing in thisSection 5.11, expressed or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of thisSection 5.11. Without limiting the foregoing, no provision of thisSection 5.11 shall create any third party beneficiary rights in any current or former employee, director or consultant of the Company in respect of continued employment or service (or resumed employment or service). Nothing contained in thisSection 5.11, express or implied, is intended to constitute an amendment to or any other modification of any Company Benefit Plan or shall prohibit the Parent from amending, suspending, or terminating any such Company Benefit Plan at any time in accordance with its terms.

Section 5.12. Certain Tax Matters.

A-53

as if the payment of such amount did not constitute income described in Sections 856(c)(2) and (3) of the Code ("Qualifying Income"), which determination shall be made by independent tax accountants to the Recipient, plus (C) if the Recipient receives a letter from outside tax counsel to the Recipient indicating that the Recipient has received a ruling from the IRS holding that the Recipient's receipt of the applicable Termination Payment either would constitute Qualifying Income or would be excluded from gross income of the Recipient for purposes of Sections 856(c)(2) and (3) of the Code, the remaining balance of such Termination Payment. Any amount of any Termination Payment that remains unpaid as of the end of a taxable year shall be paid as soon as possible during the following taxable year, subject to the foregoing limitation of this paragraph, provided that no such payment need be made after the fifth anniversary of the date of termination.

The Board of Directors
Cogdell Spencer Inc.
4401 Barclay Downs Drive, Suite 300
Charlotte, North Carolina 28209

The Board of Directors:

You have requested our opinion as to the fairness, from a financial point of view, to holders of the common stock of Cogdell Spencer Inc. ("Cogdell Spencer REIT") of the Merger Consideration (defined below) to be received by such holders pursuant to the terms and subject to the conditions set forth in an Agreement and Plan of Merger (the "Agreement") proposed to be entered into among Ventas, Inc. ("Ventas") and its wholly owned subsidiaries, TH Merger Corp, Inc. ("REIT Merger Sub") and TH Merger Sub, LLC ("OP Merger Sub"), on the one hand, and Cogdell Spencer REIT and its operating partnership subsidiary, Cogdell Spencer LP ("Cogdell Spencer OP" and, together with Cogdell Spencer REIT, "Cogdell Spencer"), on the other hand. As more fully described in the Agreement, REIT Merger Sub and Cogdell Spencer REIT will be merged (the "REIT Merger") and OP Merger Sub will be merged with and into Cogdell Spencer OP (the "OP Merger" and, together with the REIT Merger, the "Mergers"). The Agreement provides that, in connection with the REIT Merger, each outstanding share of the common stock, par value $0.01 per share, of Cogdell Spencer REIT ("Cogdell REIT Common Stock") will be converted into the right to receive $4.25 in cash (the "Merger Consideration"). The Agreement further provides that, as a condition to the consummation of the Mergers, Cogdell Spencer will sell to Madison DB Acquisition, LLC or another third-party buyer Cogdell Spencer's subsidiary, MEA Holdings, Inc., through which Cogdell Spencer conducts its design-build and related advisory services business (the "Erdman Sale") and, immediately prior to the effective time of the Mergers, will declare and pay a cash dividend in an amount equal to the net cash proceeds, if any, received by Cogdell Spencer from the Erdman Sale.

In arriving at our opinion, we reviewed a draft dated December 22, 2011 of the Agreement and held discussions with certain senior officers, directors and other representatives and advisors of Cogdell Spencer concerning the business, operations and prospects of Cogdell Spencer. We reviewed certain publicly available business and financial information relating to Cogdell Spencer as well as certain financial forecasts and other information and data relating to Cogdell Spencer provided to or discussed with us by the management of Cogdell Spencer. We reviewed the financial terms of the Mergers as set forth in the Agreement in relation to, among other things: current and historical market prices of Cogdell REIT Common Stock; the historical and projected earnings and other operating data of Cogdell Spencer; and the capitalization and financial condition of Cogdell Spencer, including the liquidity requirements of, and capital resources available to, Cogdell Spencer. We analyzed certain financial, stock market and other publicly available information relating to the businesses of other companies whose operations we considered relevant in evaluating those of Cogdell Spencer and analyzed, to the extent publicly available, the financial terms of certain other transactions which we considered relevant in evaluating the Mergers. In connection with our engagement and at the direction of Cogdell Spencer REIT, we were requested to approach, and we held discussions with, third parties to solicit indications of interest in the possible acquisition of Cogdell Spencer. In addition to the foregoing, we conducted such other analyses and examinations

and considered such other information and financial, economic and market criteria as we deemed appropriate in arriving at our opinion. The issuance of our opinion has been authorized by our fairness opinion committee.

In rendering our opinion, we have assumed and relied, without independent verification, upon the accuracy and completeness of all financial and other information and data publicly available or provided to or otherwise reviewed by or discussed with us and upon the assurances of the management of Cogdell Spencer that it is not aware of any relevant information that has been omitted or that remains undisclosed to us. With respect to the financial forecasts and other information and data provided to or otherwise reviewed by or discussed with us relating to Cogdell Spencer, we have been advised by the management of Cogdell Spencer, and we have assumed, with your consent, that such forecasts and other information and data were reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of Cogdell Spencer as to the future financial performance of Cogdell Spencer.

We have not made or been provided with an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of Cogdell Spencer nor have we made any physical inspection of the properties or assets of Cogdell Spencer. We are not real estate appraisers and express no opinion as to the value of any individual property of Cogdell Spencer, or the price at which any such property may be transferable, at any time. We have been advised by the management of Cogdell Spencer, and have assumed, with your consent, that Cogdell Spencer REIT has operated in conformity with the requirements for qualification as a real estate investment trust ("REIT") for federal income tax purposes since its formation as a REIT. We have assumed, with your consent, that the Mergers and related transactions (including the Erdman Sale and any related cash dividend) will be consummated in accordance with their respective terms without waiver, modification or amendment of any material term, condition or agreement and in compliance with all applicable laws and other requirements and that, in the course of obtaining the necessary regulatory or third party approvals, consents, releases and waivers for the Mergers or related transactions, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Cogdell Spencer or the Mergers that would be material to our analyses or opinion. Representatives of Cogdell Spencer have advised us, and we also have assumed, that the final terms of the Agreement will not vary materially from those set forth in the draft reviewed by us or as otherwise described to us.

Our opinion does not address any terms (other than the Merger Consideration to be received by holders of Cogdell REIT Common Stock to the extent expressly specified herein) or other aspects or implications of the Mergers, the Erdman Sale or any other related transaction, including, without limitation, the form or structure of the Mergers or any related transaction, the consideration payable in or any tax or other consequences of the Erdman Sale, the consideration payable in respect of any other securities of Cogdell Spencer or any other agreement, arrangement or understanding to be entered into in connection with or contemplated by the Mergers, any related transaction or otherwise. We were not requested to consider, and our opinion does not address, the underlying business decision of Cogdell Spencer REIT to effect the Mergers or any related transaction, the relative merits of the Mergers or any related transaction as compared to any alternative business strategies that might exist for Cogdell Spencer or the effect of any other transaction in which Cogdell Spencer might engage. We also express no view as to, and our opinion does not address, the fairness (financial or otherwise) of the amount or nature or any other aspect of any compensation to any officers, directors

or employees of any parties to the Mergers, or any class of such persons, relative to the Merger Consideration or otherwise. We are not expressing any opinion as to the solvency or fair value of Cogdell Spencer or any part thereof or the prices at which Cogdell REIT Common Stock will trade at any time. In addition, we express no view or opinion as to, and have relied, without independent verification and with your consent, upon the assessments of representatives of Cogdell Spencer regarding, legal, regulatory, accounting, tax or similar matters relating to Cogdell Spencer, the Mergers and related transactions as to which we understand that Cogdell Spencer obtained such advice as Cogdell Spencer deemed necessary from qualified professionals. Our opinion is necessarily based upon information available to us, and financial, stock market and other conditions and circumstances existing and disclosed to us, as of the date hereof. As you are aware, the credit, financial and stock markets have been experiencing unusual volatility and we express no opinion or view as to any potential effects of such volatility on Cogdell Spencer or the Mergers.

Citigroup Global Markets Inc. has acted as financial advisor to Cogdell Spencer REIT in connection with the proposed Mergers and will receive a fee for such services, the principal portion of which is contingent upon the consummation of the Mergers. We also will receive a fee in connection with the delivery of this opinion. We and our affiliates in the past have provided, currently are providing and in the future may provide investment banking and other financial services to Cogdell Spencer and Ventas unrelated to the proposed Mergers, for which services we and our affiliates have received and expect to receive compensation including, during the two-year period prior to the date hereof, acting as (i) joint lead arranger and co-documentation agent for, and/or a lender under, $200 million and $80.8 million credit facilities of Cogdell Spencer and a $2 billion credit facility of Ventas, (ii) joint book-running manager for a $65 million preferred stock offering of Cogdell Spencer REIT in 2010, a $45.5 million common stock offering of Cogdell Spencer REIT in 2010 and a $700 million and $400 million notes offering of Ventas in 2011 and 2010, respectively, and (iii) co-sales agent for a $40 million equity distribution program by Cogdell Spencer REIT commenced in 2010. In the ordinary course of business, we and our affiliates may actively trade or hold the securities of Cogdell Spencer REIT and Ventas for our own account or for the account of our customers and, accordingly, may at any time hold a long or short position in such securities. We and our affiliates (including Citigroup Inc. and its affiliates) may maintain relationships with Cogdell Spencer, Ventas and their respective affiliates.

Our advisory services and the opinion expressed herein are provided for the information of the Board of Directors of Cogdell Spencer REIT (in its capacity as such) in its evaluation of the proposed Mergers, and our opinion is not intended to be and does not constitute a recommendation to any security holder as to how such security holder should vote or act on any matters relating to the proposed Mergers or otherwise.
