SECTION 1 - REGISTRANT'S BUSINESS AND OPERATIONS

Item 1.01.  Entry Into a Material Definitive Agreement

         Merger Agreement
         ----------------

         On May 12, 2006, Brookdale Senior Living Inc. (the "Company"), Beta
Merger Sub Corporation, a Delaware corporation and a wholly-owned subsidiary of
the Company ("Merger Sub"), and American Retirement Corporation, a Tennessee
corporation ("ARC"), entered into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which Merger Sub will be merged with and into ARC (the
"Merger") with ARC continuing as the surviving corporation and a wholly-owned
subsidiary of the Company.

           Under the terms of the Merger Agreement, upon consummation of the
Merger, each outstanding share of common stock, par value $0.01 per share, of
ARC ("ARC Common Stock"), together with the rights issued pursuant to the Rights
Agreement, dated as of November 18, 1998, between ARC and American Stock
Transfer and Trust Company, will be converted into the right to receive $33.00
per share in cash. All of the options to purchase ARC Common Stock, whether
vested or unvested, will be cancelled and each holder of any such option will be
entitled to receive a cash payment equal to the product of (i) the excess of
$33.00 over the applicable option exercise price, and (ii) the number of shares
of ARC Common Stock for which the options had not been previously exercised.

          Consummation of the Merger is subject to the satisfaction of various
conditions, including (i) the approval of the Merger Agreement by a majority of
ARC's shareholders, (ii) the expiration or termination of any waiting period
applicable to the Merger under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, and (iii) certain other closing conditions customary for transactions
of this type. The Merger Agreement contains certain termination rights and
certain provisions that require ARC to pay the Company a termination fee of up
to $45 million and/or reimburse the Company for its expenses up to $5 million
under certain specified circumstances.

         ARC has made customary representations and warranties and covenants in
the Merger Agreement, including among others (i) to cause a meeting of ARC's
shareholders to be held to consider the adoption of the Merger Agreement, and
(ii) that ARC's board of directors will recommend that ARC's shareholders adopt
the Merger Agreement and approve the Merger, in each case, subject to certain
exceptions.

         The preceding summary of certain provisions of the Merger Agreement and
the transactions contemplated thereby, including the Merger, is qualified in its
entirety by reference to the Merger Agreement and the press release attached
hereto as Exhibit 2.1 and 99.1, respectively, and incorporated herein by
reference.

         Investment Agreement and Option Agreement
         -----------------------------------------

         Simultaneously with entering into the Merger Agreement, in order to
finance the Merger, the Company entered into an Investment Agreement (the
"Investment Agreement") with RIC Coinvestment Fund LP ("RIC"), an affiliate of
our largest stockholder, Fortress Investment Group LLC. Under the terms of the
Investment Agreement, RIC committed to purchase, at and simultaneously with the
closing of the Merger (the "Closing"), up to $1.3 billion of common stock of the
Company, par value $0.01 per share ("BKD Common Stock"), at a price of $36.93
per share (the "Financing"). The issuance of these securities will be made
pursuant to an exemption from registration provided by Section 4(2) of the
Securities Act of 1933, as amended.

         Prior to the Closing, the Company may reduce RIC's $1.3 billion
commitment to an amount equal to or greater than $650 million (the "Equity
Reduction"). If the Company does not reduce RIC's $1.3 billion commitment
(pursuant to an Equity Reduction) using the net proceeds received by the Company
pursuant to an offering of its equity securities that is consummated prior to
the Closing, RIC will issue to the Company, at the Closing, a one-time option
(the "Option Agreement") to purchase from RIC a number of shares of BKD Common
Stock having a value equal to the difference between (i) $1.3 billion less any
portion of the Equity Reduction and (ii) $650 million. Pursuant to the Option
Agreement, the Company shall have the right and the option (but not the
obligation) to purchase the shares at a price per share of $38.07. The option is
immediately vested upon issuance at the Closing and will expire six months and
one day after the Closing.

         To consider the terms of the Investment Agreement and the Option
Agreement, the board of directors of the Company (the "Board") established a
Special Committee of the Board (the "Special Committee"). The Special Committee
engaged Bear, Stearns & Co. Inc. ("Bear Stearns") to assist it in analyzing and
evaluating the Financing and to render an opinion to the Special Committee as to
the fairness to the Company, from a financial point of view, of the terms and
price to be paid to the Company for the BKD Common Stock issued to RIC in
connection with the Financing. The foregoing summary of Bear Stearns' opinion is
qualified in its entirety by reference to the full text of the opinion.

         The preceding summaries of certain provisions of the Investment
Agreement and the Option Agreement are qualified in their entirety by reference
to the Investment Agreement, the form of Option Agreement and the press release,
attached hereto as Exhibit 10.1, 10.2 and 99.1, respectively, and incorporated
herein by reference.

         Employment Agreements
         ---------------------

         As a condition to the Merger, the Company entered into employment
agreements, to take effect at the Closing, with W.E. Sheriff, ARC's Chief
Executive Officer, and certain other executive officers of ARC, including
Gregory B. Richard, George T. Hicks, Bryan D. Richardson, H. Todd Kaestner, and
James T. Money (each of Messrs. Richard, Hicks, Richardson, Kaestner, and Money,
an "Other ARC Officer", and together, the "Other ARC Officers"), regarding their
continued service with the Company following the consummation of the Merger. The
material terms of these agreements are described below.

         Sheriff Employment Agreement

         The material terms of Mr. Sheriff's employment agreement (the "Sheriff
Employment Agreement") are substantially similar to the material terms of the
existing employment agreement between the Company and its Chief Executive
Officer, including with respect to rights and obligations upon termination of
employment and entitlement to certain employee benefits. Under the terms of the
Sheriff Employment Agreement, Mr. Sheriff is to be employed following the
Closing as Co-Chief Executive Officer of the Company. The Sheriff Employment
Agreement has an initial term of approximately three years, at the end of which
the agreement automatically extends on an annual basis for up to two additional
one-year terms, unless notice not to renew the agreement is given by either
party 90 days prior to the expiration of its term.

         Mr. Sheriff's base salary under the employment agreement is $200,000
per year. Mr. Sheriff is also eligible to receive a discretionary bonus in an
amount to be determined by the Board in its sole discretion, with a target bonus
in the first year following the effective date of the Merger (the "Effective
Date") of $200,000, payable in a combination of 50% cash and 50% vested shares
of BKD Common Stock.

         As a condition to entering into the employment agreement, Mr. Sheriff
has agreed to invest $9,508,073 in BKD Common Stock at a price of $38.07 per
share, which shares shall be subject to an 18-month holding period. Mr. Sheriff
will also be granted a number of restricted shares of BKD Common Stock equal to
the number of shares Mr. Sheriff acquires pursuant to this obligation. Eighty
percent (80%) of these restricted shares will vest upon the attainment of
performance goals and 20% of these shares will vest based upon continued
employment with the Company.

         The preceding summary of certain provisions of the Sheriff Employment
Agreement is qualified in its entirety by reference to the Sheriff Employment
Agreement, attached hereto as Exhibit 10.3, and incorporated herein by
reference.

         Other Employment Agreements

         The material terms of the employment agreements with each of the Other
ARC Officers (the "Other Employment Agreements") are substantially similar to
the material terms of the existing employment agreements between the Company and
its current executive officers (other than its Chief Executive Officer),
including with respect to rights and obligations upon termination of employment
and entitlement to certain employee benefits, and are substantially similar to
the material terms of each Other Employment Agreement, with the following
material differences:

Other ARC Officer         Amount Required          Base Salary      Target Bonus
- -----------------         ---------------          -----------      ------------
                           to Re-Invest
                           ------------
                         in BKD Common Stock
                         -------------------

Gregory B. Richard            $1,116,878             $200,000         $150,000
George T. Hicks               $1,982,460             $175,000         $150,000
Bryan D. Richardson           $1,751,898             $175,000         $150,000
H. Todd Kaestner              $2,000,000             $175,000         $150,000
James T. Money                $1,750,000             $175,000         $125,000

         Under the terms of the Other Employment Agreements, each Other ARC
Officer is to be employed following the Closing as an Executive Vice President
of the Company. The Other Employment Agreements have an initial term of
approximately three years, at the end of which the agreements automatically
extend on an annual basis for up to two additional one-year terms, unless notice
not to renew the agreement is given by either party 90 days prior to the
expiration of its term.

         Pursuant to the Other Employment Agreements, target bonuses for the
first year following the Effective Date will be paid 50% in cash and 50% in
vested shares of BKD Common Stock, based on achievement of certain performance
standards as determined by the Board in its sole discretion.

         As a condition to entering into the Other Employment Agreements, each
Other ARC Officer has agreed to invest an amount specified in his respective
agreement in BKD Common Stock at a price of $38.07 per share, which shares will
be subject to an 18-month holding period. Each Other ARC Officer will also be
granted a number of restricted shares of BKD Common Stock equal to the number of
shares that such Other ARC Officer acquires pursuant to this obligation. Seventy
percent (70%) of these restricted shares will vest upon the attainment of
performance goals and 30% of these shares will vest based upon continued
employment with the Company.

         The preceding summary of certain provisions of the Other Employment
Agreements is qualified in its entirety by reference to the form of employment
agreement, attached hereto as Exhibit 10.4, and incorporated herein by
reference.
