Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On March 28, 2006, we filed with the office of the State Department of Assessments and Taxation of Maryland Articles of Amendment to our Articles of Amendment and Restatement to increase the number of shares of stock which we have the authority to issue from 31,000,000 to 51,000,000 shares, consisting of 50,000,000 shares of common stock, $0.01 par value per share, and 1,000,000 shares of preferred stock, $0.01 par value per share. The Articles of Amendment were effective upon filing.

Item 7.01. Regulation FD Disclosure.

On March 31, 2006, we filed a prospectus supplement, or Prospectus Supplement, to our prospectus dated January 28, 2005 under our Registration Statement on Form S-3, File No. 333-121910, with the Securities and Exchange Commission in connection with a public offering and sale or, the Offering, of 10,000,000 shares of our common stock, par value $.01 per share (plus additional shares to cover an over-allotment option).

The Prospectus Supplement contains certain information that was previously nonpublic including, without limitation,

•our intention to terminate six management agreements with Sunrise Senior Living Services, Inc., or SLS, following the Offering and to pay termination fees to SLS currently expected to total approximately $57.1 million in connection therewith, which amount may change if we terminate different management agreements than those we are currently contemplating. These termination fees will be recorded as expenses in our income statement in the quarter in which we give the termination notices, which we expect to be either our first or second quarter ending March 31, 2006 or June 30, 2006, respectively;

•our expectation to fund these termination fees with a portion of the proceeds of the Offering;

•our expectation of incurring a significant loss in either the quarterly period ending March 31, 2006 or June 30, 2006 and for all of 2006, as a result of the termination of the six SLS management agreements;

•that we may possibly terminate the 11 SLS management agreements that will remain after the Offering sometime in the future;

•that the results of operations at the 17 communities that SLS manages for us have historically been volatile and unpredictable, that over the last six months the income we have realized from these communities has also declined, and, as a result, the performance of these communities may adversely affect our consolidated results of operations for our quarter ending March 31, 2006;

•our belief that (even though fully reliable financial information about the current operations at these hospitals is not presently available) in 2005 the two rehabilitation hospitals that we have entered into an agreement to lease from Senior Housing Properties Trust, or Senior Housing, generated in excess of $100 million of revenues, received about 70% of their

2

revenues from the Medicare program and generated operating margins that are significantly greater than operating margins of our nursing homes; and

•unaudited consolidated pro forma financial statements that present our financial position for the year ended at and as of December 31, 2005 as if the following had occurred: (1) our acquisition of Gordon Health Ventures, LLC, or Gordon, communities, including the related sale leaseback and line of credit financing entered to fund the Gordon acquisition, (2) our August 2005 equity offering, and (3) our termination of 12 SLS management agreements in November 2005, including the payment of related termination fees to SLS, the reduction in our management fees payable to SLS in respect of those 12 management agreements and the related sale leaseback transaction with Senior Housing of the six Gordon communities; the Offering and the use of a portion of the proceeds from the Offering to pay the termination fees for six SLS management agreements we intend to terminate, including the reduction in our management fees payable to SLS in respect of those management agreements, as if all of these events had been completed as of January 1, 2005.

Item 8.01. Other Events.

On March 31, 2006, we agreed to sell 10,000,000 shares of common stock in an underwritten public offering. The public offering price was $10.45 per share. We expect to issue and deliver these shares on or about April 5, 2006. We have granted the underwriters a 30-day option to purchase up to an additional 1,500,000 shares to cover over-allotments, if any. We expect to use a portion of the approximately $98.8 million of net proceeds of the offering (after estimated expenses and underwriters’ commissions) to fund the termination payments which we expect to pay to SLS and for general business purposes, including reducing amounts outstanding under our revolving credit facility, working capital for the hospitals that we expect to begin operating later this year and possibly for terminations of additional SLS management agreements.

This Current Report on Form 8-K does not constitute an offer to sell or the solicitation of an offer to buy any of these shares. The offering of these shares will be made only by means of a prospectus supplement and accompanying prospectus. In addition, this Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of these shares in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.

WARNING CONCERNING FORWARD LOOKING STATEMENTS

THIS CURRENT REPORT ON FORM 8-K CONTAINS FORWARD LOOKING STATEMENTS WITHIN THE MEANING OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995 AND FEDERAL SECURITIES LAWS. THESE STATEMENTS REFLECT OUR INTENT, BELIEF OR EXPECTATION, OR THE INTENT, BELIEFS OR EXPECTATIONS OF OUR DIRECTORS AND OFFICERS, BUT THEY ARE NOT GUARANTEED TO OCCUR. FOR EXAMPLE,

3

•THE TERMINATION OF OUR SLS MANAGEMENT AGREEMENTS MAY NOT IMPROVE OUR FINANCIAL RESULTS OR MAY CAUSE US TO EXPERIENCE OPERATING LOSSES. SLS MAY DISPUTE OUR CALCULATION OF THE TERMINATION FEES FOR THE SIX AGREEMENTS WE INTEND TO TERMINATE. THE OPERATING AND FINANCIAL PERFORMANCE OF THE COMMUNITIES MAY DETERIORATE IN THE PERIOD AFTER WE NOTIFY SLS OF OUR INTENTION TO TERMINATE THE AGREEMENTS AND BEFORE WE ARE ALLOWED TO ASSUME THE COMMUNITIES’ OPERATIONS PURSUANT TO THE AGREEMENT TERMS. ALTHOUGH OUR EXPECTATION IS OTHERWISE, WE MAY BE UNABLE TO OPERATE THESE COMMUNITIES FOR OUR OWN ACCOUNT IN A MANNER WHICH IS AS PROFITABLE AS THEY HAVE BEEN OPERATED BY SLS,

•WE MAY BE UNABLE TO TERMINATE THE 11 SLS MANAGEMENT AGREEMENTS THAT WILL REMAIN AFTER THE OFFERING FOR VARIOUS REASONS, INCLUDING BECAUSE WE MAY BE UNABLE TO FUND THE TERMINATION FEES. AS A RESULT, THE INCOME WE REALIZE FROM THESE 11 COMMUNITIES MAY CONTINUE TO DECLINE,

•WE MAY NOT RECEIVE THE REQUIRED REGULATORY APPROVALS TO LEASE THE TWO HOSPITALS FROM SENIOR HOUSING AND OUR LEASE WITH SENIOR HOUSING MAY NOT BECOME EFFECTIVE. HEALTHSOUTH CORPORATION’S LEASE OF THESE HOSPITALS MAY BE REINSTATED AND OUR LEASE OF THESE HOSPITALS MAY BE TERMINATED. OPERATING MARGINS FOR THESE HOSPITALS MAY BE LOWER THAN WE NOW ANTICIPATE OR MAY DECLINE. WE ALSO MAY BE UNABLE TO OPERATE THESE HOSPITALS PROFITABLY AND WE MAY EXPERIENCE LOSSES FROM OUR OPERATION OF THESE HOSPITALS, OR

•FURTHER, THE FACT THAT THE OFFERING HAS PRICED MAY IMPLY THAT THE OFFERING WILL CLOSE. THE CLOSING IS SUBJECT TO CONDITIONS CUSTOMARY TO TRANSACTIONS OF THIS TYPE AND MAY BE DELAYED OR MAY NOT OCCUR AT ALL. THE FACT THAT THE UNDERWRITERS HAVE AN OVER-ALLOTMENT OPTION MAY IMPLY THAT THIS OPTION WILL BE EXERCISED. THE UNDERWRITERS ARE NOT UNDER ANY OBLIGATION TO EXERCISE THIS OPTION, OR ANY PORTION OF IT, AND MAY NOT DO SO. IN ADDITION, THE AMOUNT OF AND THE INTENDED USE OF PROCEEDS FROM THE OFFERING MAY CHANGE. THESE FORWARD LOOKING STATEMENTS ARE BASED UPON OUR PRESENT EXPECTATIONS, BUT THESE STATEMENTS AND THE IMPLICATIONS OF THESE STATEMENTS ARE NOT GUARANTEED.

IN ANY SUCH EVENT, OUR FUTURE FINANCIAL PERFORMANCE MAY BE ADVERSELY AFFECTED AND WE MAY EXPERIENCE LOSSES. IF OUR FINANCIAL RESULTS DO NOT IMPROVE, OUR STOCK PRICE LIKELY WILL DECLINE. YOU SHOULD NOT PLACE UNDUE RELIANCE UPON OUR FORWARD LOOKING STATEMENTS.

4

EXCEPT AS MAY BE REQUIRED BY APPLICABLE LAW, WE DO NOT INTEND TO IMPLY THAT WE WILL RELEASE PUBLICLY THE RESULT OF ANY REVISION TO THE FORWARD LOOKING STATEMENTS CONTAINED IN THIS CURRENT REPORT ON FORM 8-K TO REFLECT THE FUTURE OCCURRENCE OF PRESENTLY UNANTICIPATED EVENTS.

Ladies and Gentlemen:

Five Star Quality Care, Inc., a Maryland corporation (the “Company”), proposes to issue and sell to the underwriters named in Schedule A annexed hereto (the “Underwriters”) an aggregate of 10,000,000 shares of Common Stock, $0.01 par value per share (the “Common Stock”), of the Company (the “Firm Shares”). In addition, solely for the purpose of covering over-allotments, the Company proposes to grant to the Underwriters the option to purchase from the Company up to an additional 1,500,000 shares of Common Stock (the “Additional Shares”). The Firm Shares and the Additional Shares are hereinafter collectively sometimes referred to as the “Shares.” The Shares are described in the Prospectus which is referred to below.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), a registration statement (file number 333-121910) on Form S-3 under the Act (the “universal shelf registration statement”), including a prospectus relating to, among other things, debt securities, shares of common and preferred stock, depositary shares, warrants and stock purchase contracts and equity units of the Company, and such amendments to such registration statement, as may have been required prior to the date hereof, have been similarly prepared and have been filed with the Commission. Such universal shelf registration statement, as so amended, and any post-effective amendments thereto, have been declared by the Commission to be effective under the Act. Such universal shelf registration statement, as amended at the date of this Agreement, meets the requirements set forth in Rule 415(a)(1)(x) under the Act and complies in all other material respects with said Rule.

The Company will next file with the Commission pursuant to Rule 424(b) under the Act a final prospectus supplement to the basic prospectus included in the universal shelf registration statement, as so amended, describing the Shares and the offering thereof, in such form as has been provided to or discussed with, and approved, by the Underwriters.

Except where the context otherwise requires, the term “Registration Statement” as used in this Agreement means the universal shelf registration statement, as amended at the time it became effective for purposes of Section 11 of the Act, as such section applies to the respective Underwriters (the “Effective Time”), including (i) all documents filed as part thereof or incorporated by reference or deemed to be incorporated by reference therein and (ii) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430A, Rule 430B or Rule 430C under the Act, to be part of the registration statement at the Effective Time.  If an abbreviated registration statement is prepared and filed with the Commission in accordance with Rule 462(b) under the Act (an “Abbreviated Registration Statement”), the term “Registration Statement” includes the Abbreviated Registration Statement. Any such Abbreviated Registration Statement shall be filed by the Company with the Commission and become effective no later than 10:00 P.M., New York City time, on the date of determination of the public offering price for the Shares.

Except where the context otherwise requires, the term “Prospectus Supplement” as used in this Agreement means any final prospectus supplement specifically relating to the Shares, in the form filed with, or transmitted for filing to, the Commission pursuant to Rule 424 under the Act. Except where the context otherwise requires, the term “Prospectus” as used in this Agreement means the Basic Prospectus together with the Prospectus Supplement, except that if such Basic Prospectus is amended or supplemented on or prior to the date on which the Prospectus Supplement was first filed pursuant to Rule 424, the term “Prospectus” shall refer to the Basic Prospectus as so amended or supplemented and as supplemented by the Prospectus Supplement.

“Permitted Free Writing Prospectuses,” as used herein, means the document attached hereto as Annex A and each “road show” (as defined in Rule 433 under the Act), if any, related to the offering of the Shares contemplated hereby that is a “written communication” (as defined in Rule 405 under the Act) (each such road show, a “Road Show”). Each Underwriter represents, severally and not jointly, that it has not offered or sold and will not offer or sell, without the Company’s consent, any Shares by means of any “free writing prospectus” (as defined in Rule 405 under the Act) that is required to be filed by the Underwriters with the Commission pursuant to Rule 433 under the Act, other than a Permitted Free Writing Prospectus.

Any reference in this Agreement to the universal shelf registration statement, the Registration Statement, the Basic Prospectus, any Prepricing Prospectus, any Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the documents incorporated by reference therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents.

The Company and the Underwriters agree as follows:

1.Sale and Purchase.  On the basis of the representations and warranties and subject to the terms and conditions herein set forth, the Company agrees to issue and sell to each Underwriter and, upon the basis of the representations, warranties and agreements of the Company herein contained and subject to all the terms and conditions set forth herein, each Underwriter agrees, severally and not jointly, to purchase from the Company, at a purchase price of $9.902 per Share (the “purchase price per share”), the number of Firm Shares set forth opposite the name of such Underwriter in Schedule A annexed hereto (or such number of Firm Shares increased as set forth in Section 8 hereof).

The Company is advised by you that the Underwriters intend (i) to make a public offering of their respective portions of the Firm Shares as soon after the date hereof as in your judgment is advisable and (ii) initially to offer the Firm Shares upon the terms set forth in the Prospectus. You may from time to time increase or decrease the public offering price after the initial public offering to such extent as you may determine.

In addition, the Company hereby grants to the several Underwriters the option to purchase, and upon the basis of the representations, warranties and agreements of the Company and subject to the terms and conditions herein set forth, the Underwriters shall have the right to purchase, severally and not jointly, from the Company all or a portion of the Additional Shares as may be necessary to cover over-allotments made in connection with the offering of the Firm Shares, at the same purchase price per share to be paid by the Underwriters to the Company for the Firm Shares. This option may be exercised by you on behalf of the several Underwriters at any time on or before the 30th day following the date hereof by written notice to the Company. Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised and the date and time when the Additional Shares are to be delivered (such date and time being herein referred to as the “additional time of purchase”); provided, however, that the additional time of purchase shall not be earlier than the time of purchase (as defined

4

below) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the tenth business day after the date on which the option shall have been exercised. The number of Additional Shares to be sold to each Underwriter shall be the number which bears the same proportion to the aggregate number of Additional Shares being purchased as the number of Firm Shares set forth opposite the name of such Underwriter on Schedule A hereto bears to the total number of Firm Shares (subject, in each case, to such adjustment as you may determine solely to eliminate fractional shares).

As used herein “business day” shall mean a day on which the New York Stock Exchange is open for trading.

2.Payment and Delivery. Payment of the purchase price for the Firm Shares shall be made to the Company by Federal Funds wire transfer, against delivery of the certificates for the Firm Shares to you through the facilities of the Depository Trust Company (“DTC”) for the respective accounts of the Underwriters. Such payment and delivery shall be made at 10:00 A.M., New York City time, on April 5, 2006 (unless another time shall be agreed to by you and the Company or unless postponed in accordance with the provisions of Section 8 hereof). The time at which such payment and delivery are actually made is hereinafter called the “time of purchase.” Electronic transfer of the Firm Shares shall be made to you at the time of purchase in such names and in such denominations as you shall specify, such specification to be made by you no later than the second business day preceding the time of purchase.

Payment of the purchase price for the Additional Shares shall be made at the additional time of purchase in the same manner and at the same office as the payment for the Firm Shares. Electronic transfer of the Additional Shares shall be made to you at the additional time of purchase in such names and in such denominations as you shall specify, such specification to be made by you no later than the second business day preceding the time of purchase.

Deliveries of the documents described in Section 6 below with respect to the purchase of the Shares shall be made at the offices of Dewey Ballantine LLP, 1301 Avenue of the Americas, New York, New York at 10:00 A.M., New York City time, on the date of the closing of the purchase of the Firm Shares or the Additional Shares, as the case may be.

7.Effective Date of Agreement; Termination. This Agreement shall become effective: (i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at the time this Agreement is executed and delivered, it is necessary for the registration statement or a post-effective amendment thereto or an Abbreviated Registration Statement to be declared or become effective before the offering of the Shares may commence, when notification of the effectiveness of the registration statement or such post-effective amendment has been released by the Commission or such Abbreviated Registration Statement has, pursuant to the provisions of Rule 462 under the Act, become effective. Until such time as this Agreement shall have become effective, it may be terminated by the Company by notifying you, or by you, as representatives of the Underwriters, by notifying the Company.

The obligations of the several Underwriters hereunder shall be subject to termination in the absolute discretion of UBS Securities LLC, or of any group of Underwriters (which may include UBS Securities LLC) which has agreed to purchase in the aggregate at least 50% of the Firm Shares, if (x) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Registration Statement, the Prepricing Prospectus, the Prospectus and any Permitted Free Writing Prospectus, there has been any material adverse change in the business, prospects, properties, management, financial condition or results of operations of the Company and the Subsidiaries taken as a whole, which would, in UBS Securities LLC’s judgment or in the judgment of such group of Underwriters, make it impracticable to proceed with the public offering or the delivery of the Shares on the terms and in the manner contemplated in the Registration Statement, any Disclosure Package or the Prospectus, or (y) since the time of execution of this Agreement, there shall have occurred: (i) a suspension or material limitation in trading in securities generally on the NYSE, the American Stock Exchange or the NASDAQ; (ii) a suspension or material limitation in trading in the Company’s securities on the American Stock Exchange; (iii) a

If you or any group of Underwriters elects to terminate this Agreement as provided in this Section 7, the Company and each other Underwriter shall be notified promptly by letter, telegram or telecopy.

If the sale to the Underwriters of the Shares, as contemplated by this Agreement, is not carried out by the Underwriters for any reason permitted under this Agreement or if such sale is not carried out because the Company shall be unable to comply with any of the terms of this Agreement, the Company shall not be under any obligation or liability under this Agreement (except to the extent provided in Sections 4(l), 5 and 9 hereof), and the Underwriters shall be under no obligation or liability to the Company under this Agreement (except to the extent provided in Section 9 hereof) or to one another hereunder.

8.Increase in Underwriters’ Commitments. Subject to Sections 6 and 7, if any Underwriter shall default in its obligation to purchase and pay for the Firm Shares to be purchased by it hereunder (otherwise than for a reason sufficient to justify the termination of this Agreement under the provisions of Section 7 hereof) and if the number of Firm Shares which all Underwriters so defaulting shall have agreed but failed to purchase and pay for does not exceed 10% of the total number of Firm Shares, the non-defaulting Underwriters shall purchase and pay for (in addition to the aggregate number of Firm Shares they are obligated to purchase pursuant to Section 1 hereof) the number of Firm Shares agreed to be purchased by all such defaulting Underwriters, as hereinafter provided. Such Firm Shares shall be purchased and paid for by such non-defaulting Underwriter or Underwriters in such amount or amounts as you may designate with the consent of each Underwriter so designated or, in the event no such designation is made, such Firm Shares shall be purchased and paid for by all non-defaulting Underwriters pro rata in proportion to the aggregate number of Firm Shares set opposite the names of such non-defaulting Underwriters in Schedule A.

Without relieving any defaulting Underwriter from its obligations hereunder, the Company agrees with the non-defaulting Underwriters that it will not sell any Firm Shares hereunder unless all of the Firm Shares are purchased by the Underwriters (or by substituted Underwriters selected by you with the approval of the Company or selected by the Company with your approval).

31

If a new Underwriter or Underwriters are substituted by the Underwriters or by the Company for a defaulting Underwriter or Underwriters in accordance with the foregoing provision, the Company or you shall have the right to postpone the time of purchase or the additional time of purchase, as the case may be, for a period not exceeding five business days in order that any necessary changes in the Registration Statement and Prospectus and other documents may be effected.

The term Underwriter as used in this Agreement shall refer to and include any Underwriter substituted under this Section 8 with like effect as if such substituted Underwriter had originally been named in Schedule A.

If the aggregate number of Shares which the defaulting Underwriter or Underwriters agreed to purchase exceeds 10% of the total number of Shares which all Underwriters agreed to purchase hereunder, and if neither the non-defaulting Underwriters nor the Company shall make arrangements within the five business day period stated above for the purchase of all the Shares which the defaulting Underwriter or Underwriters agreed to purchase hereunder, this Agreement shall terminate without further act or deed and without any liability on the part of the Company to any non-defaulting Underwriter and without any liability on the part of any non-defaulting Underwriter to the Company. Nothing in this paragraph, and no action taken hereunder, shall relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

9.Indemnity and Contribution.

(a)The Company agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors, officers and any person who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Underwriter or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this

Section 9 being deemed to include any Basic Prospectus, any Prepricing Prospectus, the Prospectus Supplement, the Prospectus and any amendments or supplements to the foregoing), in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company or in any Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, or arises out of or is based upon any omission or alleged omission to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except, with respect to such Prospectus or Permitted Free Writing Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Underwriter furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, such Prospectus or Permitted Free Writing Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made,  not misleading.

(b)Each Underwriter severally agrees to indemnify, defend and hold harmless the Company, its directors, officers and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and the successors and assigns of all of the foregoing persons from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Company or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information furnished in writing by or on behalf of such Underwriter through you to the Company expressly for use in, a Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c)If any action, suit or proceeding (each, a “ Proceeding”) is brought against any person in respect of which indemnity may be sought pursuant to the foregoing paragraphs (a) and (b) of this Section 9, such person (the “indemnified party”)

33

shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party) and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which it may have to such indemnified party or otherwise. Such indemnified party shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless the employment of such counsel shall have been authorized in writing by such indemnifying party in connection with the defense of such Proceeding or such indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties, but such indemnifying party may employ counsel and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such indemnifying party), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). No indemnifying party shall be liable for any settlement of any such Proceeding effected without the written consent of such indemnifying party but if settled with the written consent of such indemnifying party, such indemnifying party agrees to indemnify and hold harmless the indemnified party from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this paragraph, then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault, liability or failure to act, by or on behalf of such indemnified party.

(d)If the indemnification provided for in this Section 9 is unavailable to an indemnified party under subsections (a) and (b) of this Section 9 in respect of any

34

losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportion as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate public offering price of the Shares. The relative fault of the Company on the one hand and of the Underwriters on the other shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e)The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above. Notwithstanding the provisions of this Section 9, in no case shall any Underwriter be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay by reason of such untrue statement or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several in proportion to their respective underwriting commitments and not joint.

(f)The indemnity and contribution agreements contained in this Section 9 and the covenants, warranties and representations of the Company contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter, its partners, directors, officers or any person (including each partner, officer or director of such person) who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or

35

on behalf of the Company, its directors, officers, or any person who controls any of the foregoing within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Shares. The Company and each Underwriter agree promptly to notify each other of the commencement of any Proceeding against it and against any of the officers or directors of the Company in connection with the issuance and sale of the Shares, or in connection with the Registration Statement, the Prepricing Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

10.Notices.  Except as otherwise herein provided, all statements, requests, notices and agreements shall be in writing or by telegram and, if to the Underwriters, shall be sufficient in all respects if delivered or sent to UBS Securities LLC, 299 Park Avenue, New York, NY 10171-0026, Attention: Syndicate Department; and if to the Company, shall be sufficient in all respects if delivered or sent to the Company at the offices of the Company at 400 Centre Street, Newton, Massachusetts 02458, Attention: Evrett W. Benton, Chief Executive Officer and President.

11.Information Furnished by the Underwriters.  The statements set forth in the fourth, fifth and seventh paragraphs, and in the section entitled “Price Stabilization and Short Positions,” under the caption “Underwriting” in the Prospectus Supplement, insofar as such statements relate to (a) electronic delivery of prospectuses, (b) the amount of selling concession and reallowance and (c) price stabilization and short positions, constitute the only information furnished by or on behalf of the Underwriters as such information is referred to in Sections 3 and 9 hereof.

12.Governing Law; Construction.  This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the laws of the State of New York. The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

13.Submission to Jurisdiction.  Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and you and the Company consent to the jurisdiction of such courts and personal service with respect thereto. The Company hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against an Underwriter or any indemnified party. Each Underwriter and the Company (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Company agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and

36

binding thereupon, and may be enforced in any other courts in the jurisdiction to which the Company is or may be subject, by suit upon such judgment.

14.Parties at Interest.  The Agreement herein set forth has been and is made solely for the benefit of the Underwriters, the Company and, to the extent provided in Section 9 hereof, the controlling persons, partners, directors or officers, referred to in such section, and their respective successors, assigns, heirs, personal representatives and executors and administrators. No other person, partnership, association or corporation (including a purchaser, as such purchaser, from any of the Underwriters) shall acquire or have any right under or by virtue of this Agreement.

15.No Fiduciary Relationship.  The Company hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Company’s securities. The Company further acknowledges that the Underwriters are acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Company, its management, stockholders, creditors or any other person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Company’s securities, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions, and that any opinions or views expressed by the Underwriters to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

16.Counterparts. This Agreement may be signed by the parties in one or more counterparts that together shall constitute one and the same agreement among the parties.

17.Successors and Assigns.  This Agreement shall be binding upon the Underwriters and the Company and their successors and assigns and any successor or assign of any substantial portion of the Company’s and any of the Underwriters’ respective businesses and/or assets.

18.Miscellaneous.  UBS Securities LLC, an indirect, wholly owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS AG. Because UBS Securities LLC is a separately organized entity, it is solely responsible for its own contractual obligations and

37

commitments, including obligations with respect to sales and purchases of securities. Securities sold, offered or recommended by UBS Securities LLC are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

A lending affiliate of UBS Securities LLC may have lending relationships with issuers of securities underwritten or privately placed by UBS Securities LLC. To the extent required under the securities laws, prospectuses and other disclosure documents for securities underwritten or privately placed by UBS Securities LLC will disclose the existence of any such lending relationships and whether the proceeds of the issue will be used to repay debts owed to affiliates of UBS Securities LLC.

Five Star Quality Care, Inc.

Issuer Free Writing Prospectus Dated March 31, 2006

The information in this Issuer Free Writing Prospectus supplements, and should be considered in connection with, the information contained in the Preliminary Prospectus Supplement dated March 24, 2006 and the accompanying Prospectus dated January 28, 2005, or the preliminary prospectus, of Five Star Quality Care, Inc., or Five Star.  The following information assumes no exercise of the underwriter’s over-allotment option.

Total shares offered: The Five Star offering has been increased from 7,000,000 shares of common stock to 10,000,000 shares of common stock.  In addition, the underwriters have been granted an over-allotment option for 1,500,000 shares of common stock.

Public offering price: The public offering price is $10.45 per share.

Last reported sale price of common stock on the American Stock Exchange on March 30, 2006:  $10.45 per share.

Proceeds to Five Star: Net proceeds to Five Star from the offering, after deducting underwriting discounts and commissions and estimated offering expenses, are estimated to be approximately $98.8 million, as compared to approximately $72.5 million as reflected in the preliminary prospectus.

Common stock outstanding after the offering: Five Star shares outstanding after the offering will be approximately 30,060,934 shares, instead of 27,060,934 shares as reflected in the preliminary prospectus.

Termination fees: Five Star expects that the termination fees payable to Sunrise Senior Living Services, Inc., or SLS, for the six communities it intends to terminate will total approximately $57.1 million, as compared to $58.5 million as reflected in the preliminary prospectus.  This amount may change if Five Star terminates different management agreements than those currently contemplated.  Five Star now expects that it will deliver the termination notices to SLS, and as a result record the charge to earnings for the termination fees and report a significant loss, in the first or second quarter of 2006, as compared to the first quarter of 2006 as reflected in the preliminary prospectus.

Use of proceeds: Five Star intends to use approximately $57.1 million of the net offering proceeds to pay the termination fees to SLS relating to six communities described in the preliminary prospectus.  The $41.7 million in remaining net offering proceeds are expected to be used by Five Star for general business purposes, including for repayment of debt, for working capital and possibly for termination of additional SLS management agreements.

Pro forma information:

Five Star’s pro forma weighted average shares outstanding for the year ended December 31, 2005, as adjusted for our August equity offering and this offering, as if they occurred on January 1, 2005, would be approximately 30,061,000 shares, as compared to 27,061,000 as reflected in the preliminary prospectus.

Pro forma as adjusted earnings per share, giving effect to our acquisition of six Gordon Health Ventures, LLC, or Gordon, communities, including the related sale leaseback and line of credit financing entered into to fund the Gordon acquisition; our August 2005 equity offering; our termination of 12 SLS management agreements in November 2005, including the payment of related termination fees to SLS, the reduction in our management fees payable to SLS in respect of those 12 management agreements and the related sale leaseback transaction with Senior Housing Properties Trust of the six Gordon communities; this offering and the use of a portion of the proceeds from this offering to pay the termination fees for six SLS management agreements we intend to terminate, including the reduction in our management fees payable to SLS in respect of those management agreements, as if all of these events had been completed as of January 1, 2005, will be approximately $(4.25) per share, as compared to $(4.77) per share as reflected in the preliminary prospectus.  The pro forma loss per share includes a loss of $(4.77) per share relating to payment of SLS termination fees (consisting of $2.87 per share relating to the termination fees we incurred in 2005 and pro forma termination fees of $1.90 per share in respect of the six SLS management agreements we intend to terminate as described in the preliminary prospectus). The unaudited pro forma consolidated income statement also reflects the impact of termination fees payable to SLS of $57.1 million, as compared to $58.5 million as reflected in the preliminary prospectus.  The rest of the unaudited pro forma consolidated income statement information for the year ended December 31, 2005, as reflected in the preliminary prospectus, remains unchanged.

Pro forma as adjusted cash and cash equivalents, debt, total shareholders’ equity and total capitalization of Five Star at December 31, 2005, in each case giving effect to the offering and use of a portion of the offering proceeds to fund payment of the SLS termination fees for six SLS management agreements (and not giving effect to any possible repayment of debt or other possible uses), as if these events had been completed as of December 31, 2005, would be approximately $58.4 million, $45.3 million, $110.5 million and $155.8 million, respectively, as compared to approximately $30.7 million, $45.3 million, $82.8 million and $128.1 million as reflected in the preliminary prospectus.

This free writing prospectus includes forward looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.  These forward looking statements, which are based upon Five Star’s present beliefs and expectations, are subject to numerous risks and uncertainties, including those described under the captions “Risk factors”, “Warning concerning forward looking statements” and elsewhere in the Preliminary Prospectus Supplement dated March 24, 2006 and the accompanying Prospectus dated January 28, 2005, all of which should be carefully considered by investors before purchasing shares of our common stock in this offering.

(b) TRANSFER IN TRUST. If any Transfer of shares of Capital Stock occurs (whether or not such Transfer is the result of a transaction entered into through the facilities of the AMEX or any other national securities exchange or automated inter-dealer quotation system) which, if effective, would result in any Person Constructively Owning shares of Capital Stock in violation of Section 6.2.1(a)(i), 6.2.1(a)(ii) or 6.2.1(a)(iii), as applicable; (i) then that number of shares of Capital Stock the Constructive Ownership of which otherwise would cause such Person to violate Section 6.2.1(a)(i), 6.2.1(a)(ii) or 6.2.1(a)(iii) (rounded upward to the nearest whole share) shall be automatically transferred to a Charitable Trust for the benefit of a Charitable Beneficiary, as described in Section 6.3, effective as of the close of business on the Business Day prior to the date of such Transfer (or as of the close of business on the Effective Date as to any such Transfer that occurs on the Effective Date), and such Person shall acquire no rights in such shares of Capital Stock; or (ii) if the transfer to the Charitable Trust described in clause (i) of this sentence would not be effective for any reason to prevent the violation of Section 6.2.1(a)(i), 6.2.1(a)(ii) or 6.2.1(a)(iii), as applicable, then the Transfer of that number of shares of Capital Stock that otherwise would cause any Person to violate Section 6.2.1(a)(i) or 6.2.1(a)(ii) or 6.2.1(a)(iii), as applicable, shall be void ab initio, and the intended transferee shall acquire no rights in such shares of Capital Stock.

that will or may violate Section 6.2.1(a), or any Person who would have owned shares of Capital Stock that resulted in a transfer to the Charitable Trust pursuant to the provisions of Section 6.2.1(b), shall immediately give written notice to the Corporation of such event, or in the case of such a proposed or attempted transaction, give at least 15 days prior written notice, and shall provide to the Corporation such other information as the Corporation may request in order to determine the effect, if any, of such acquisition or ownership on SNH’s status as a REIT and the Corporation’s compliance with its covenants with SNH with respect thereto.

Section 6.2.4 OWNE RS REQUIRED TO PROVIDE INFORMATION. During the period commencing at the Effective Time and ending at the close of business on the Restriction Termination Date:

Each such stockholder of record and each Actual Owner shall provide to the Corporation such additional information as the Corporation may request in order to determine the effect, if any, of such ownership on SNH’s status as a REIT and to ensure compliance with the Ownership Limit and the Corporation’s compliance of its covenants with SNH with respect thereto.

(b) Each Person who is a Constructive Owner of shares of Capital Stock and each Person (including the stockholder of record) who is holding shares of Capital Stock for a Constructive Owner shall provide to the Corporation such information as the Corporation may request, in good faith, in order to help determine SNH’s status as a REIT and the Corporation’s compliance of its covenants with SNH with respect thereto.

Section 6.2.5 REMEDIES NOT LIMITED.

10

Section 6.2.7 EXCEPTIONS.

(a) The Board of Directors, in its sole and absolute discretion, may grant to any Person who makes a request therefor (a “Requesting Person”) an exception to the Ownership Limit (or one or more elements thereof) with respect to the ownership of any series or class of Capital Stock of the Corporation, subject to the following conditions and limitations: (i) (A) the Board of Directors shall have determined, in its sole and absolute discretion, that the Requesting Person’s ownershi p of shares of Capital Stock in excess of the Ownership Limit pursuant to the exception requested hereunder (together with the ownership of shares of Capital Stock by all other Persons as permitted under this Article VI, taking into account any previously granted exceptions pursuant hereto) would not cause the Corporation or any Person in which the Corporation owns, directly or indirectly, any equity interest and which is a tenant of SNH or any entity in which SNH owns any equity interest, to be considered a “related party tenant” with respect to SNH for purposes of Section 856(d)(2)(B) of the Code, (B) the Board of Directors shall have determined, in its sole and absolute discretion, that the Requesting Person’s ownership of shares of Capital Stock in excess of the Ownership Limit pursuant to the exception requested hereunder (together with the ownership of shares of Capital Stock by all other Persons as permitted under this Article VI, taking into account any previously granted exceptions pu rsuant hereto) would not cause a default under the terms of any lease relating to real or personal property pursuant to which the Corporation is a party or reasonably expects to become a party, (C) the Board of Directors shall have determined, in its sole and absolute discretion, and in the case of each individual director, in his or her business judgment, that the Requesting Person’s ownership of shares of Capital Stock in excess of the Ownership Limit pursuant to the exception requested hereunder (together with the ownership of shares of Capital Stock by all other Persons as permitted under this Article VI, taking into account any previously granted exceptions pursuant hereto) is in the best interests of the Corporation, and (D) SNH shall have consented, in writing, to such exception; and (ii) such Requesting Person provides to the Board of Directors, for the benefit of both the Corporation and SNH, such representations and undertakings, if any, as the Board of Directors or SNH may, in their sole and absolute discretion of each of them, determine to be necessary in order for it to make the determination that the conditions set forth in clause (A) above of this Section 6.2.7(a)  have been and/or will continue to be satisfied (including, without limitation, an agreement as to a reduced Ownership Limit or Excepted Holder Limit for such Requesting Person with respect to the Constructive Ownership of one or more other classes or series of shares of Capital Stock not subject to the exception), and such Requesting Person agrees that any violation of such representations and undertakings or any attempted violation thereof will result in the application of the remedies set forth in Section 6.2 with respect to shares of Capital Stock held in excess of the Ownership Limit or the Excepted Holder Limit (as may be applicable) with respect to such Requesting Person (determined without regard to the exception granted such Requesting Person under this subparagraph (a)). If a member of the Board of Directors requests that the Board of Directors grant an exception pursuant to this subparagraph (a) with respect to such member, or with respect to any other Person if such member of the Board of Directors would be considered to be the Constructive Owner of shares of Capital Stock owned by such other Person, such member of the Board of Directors shall not participate in the decision of the Board of Directors as to whether to grant any such exception.

11

(b) Prior to granting any exception or exemption pursuant to subparagraph (a), the Board of Directors may require a ruling from the IRS and/or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors, in its sole and absolute discretion as it may deem necessary or advisable in order to determine or ensure SNH’s status as a REIT; provided, however, that the Board of Directors shall not be obligated to require obtaining a favorable ruling or opinion in order to grant an exception hereunder.

(c) An underwriter or initial purchaser that participates in a public offering or a private placement of shares of Capital Stock (or securities convertible into or exchangeable for shares of Capital Stock) may Constructively Own shares of Capital Stock (or securities convertible into or exchangeable for shares of Capital Stock) in excess of the Ownership Limit, but only to the extent necessary to facilitate such public offering or private placement; and provided, that the ownership of shares of Capital Stock by such underwriter or initial purchaser would not result in the Corporation or any Person in which the Corporation owns, directly or indirectly, any equity interest and which is a tenant of SNH or any entity in which SNH owns any equity interest, to be considered a “related party tenant” with respect to SNH for purposes of Section 856(d)(2)(B) of the Code.

(d) The Board of Directors may reduce the Excepted Holder Limit for an Excepted Holder only (1) with the written consent of such Excepted Holder at any time or (2) pursuant to the terms and conditions of the agreements and undertakings entered into with such Excepted Holder in connection with the establishment of the Excepted Holder Limit for that Excepted Holder.

Section 6.2.8 INCREASE OR DECREASE IN OWNERSHIP LIMIT. The Board of Directors may from time to time increase or decrease the Ownership Limit, subject to the limitations provided in this Section 6.2.8.

(a) Any decrease may be made only prospectively as to subsequent holders (other than a decrease as a result of a retroactive change in existing law, in which case such change shall be effective immediately).

(b) The Ownership Limit may not be increased without the written consent of SNH.

Section 6.2.9 LEGEND. Each certificate for shares of Capital Stock (or securities exercisable fo r or convertible into shares of Capital Stock) shall bear substantially the following legend:

The shares of Capital Stock represented by this certificate are subject to restrictions on Constructive Ownership and Transfer primarily for the purpose of assisting Senior Housing Properties Trust, a Maryland real estate investment trust, in maintaining its status as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). Except as expressly provided in the Corporation’s charter, (i) no Person may Constructively Own shares of Common Stock of the Corporation in excess of

12

9.8 percent (in value or number of shares, whichever is more restrictive) of the outstanding shares of Common Stock of the Corporation unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable)  or an Excluded Holder (in which case the Excluded Holder Limit shall be applicable); and (ii) with respect to any class or series of shares of Capital Stock other than Common Stock, no Person may Constructively Own more than 9.8 percent (in value or number of shares, whichever is more restrictive) of the outstanding shares of such class or series of such Capital Stock of the Corporation (collectively, (i) and (ii) are referred to herein as the “Ownership Limit”), unless such Person is an Excepted Holder (in which case the Excepted Holder Limit shall be applicable) or an Excluded Holder (in which case the Excluded Holder Limit shall be applicable). Notwiths tanding the foregoing, commencing at the time at which the distribution by Senior Housing Properties Trust, a Maryland real estate investment trust, of the Capital Stock of the Corporation (the “Distribution”) is effective, no Excluded Holder shall Constructively Own shares of Capital Stock in excess of the Excluded Holder Limit for such Excluded Holder. An “Excepted Holder” means a stockholder of the Corporation for whom an Excepted Holder Limit is created by the Board of Directors. An “Excluded Holder” means any Person who acquires Constructive Ownership of shares of Common Stock solely by reason of the Transfer of Common Stock in the Distribution and who, immediately following the Distribution,  Constructively Owns shares of Common Stock in excess of the Ownership Limit solely by reason of the Transfer of Common Stock in the Distribution. The “Excluded Holder Limit” means, with respect to any Excluded Holder, the shares of Capital Stock that such Excluded Holde r was considered to Constructively Own immediately following the Distribution solely by reason of the Distribution (taking into account only such shares of Capital Stock and no other shares as to which such Person may thereafter become, for any reason, the Constructive Owner), provided, however, that (i) if the amount of shares of Capital Stock such Excluded Holder is considered to constructively own decreases by disposition or otherwise, but remains higher than the Ownership Limit, then such decreased amount shall become the Excluded Holder Limit, and (ii) if at any time the Excluded Holder Limit for any Excluded Holder would be less than the Ownership Limit, such Excluded Holder shall cease to be an Excluded Holder and the Ownership Limit shall thereafter apply to such Person. Any Person who Constructively Owns or attempts to Constructively Own shares of Capital Stock which cause or will cause a Person to Constructively Own shares of Capital Stock in excess or in violation of the above limitations must imm ediately notify the Corporation. If any of the restrictions on Transfer are violated, the shares of Capital Stock represented hereby will be automatically transferred to a Charitable Trustee of a Charitable Trust for the benefit (except as otherwise provided in the charter of the Corporation) of one or more Charitable Beneficiaries. In addition, upon the occurrence of certain events, attempted Transfers in violation of the restrictions described above may be void ab initio. A Person who attempts to Constructively Own shares of Capital

13

Stock in violation of the Transfer restrictions described above shall have no claim, cause of action or any recourse whatsoever against a transferor of such shares of Capital Stock. All capitalized terms in this legend have the meanings defined in the Corporation’s charter, as the same may be amended from time to time, a copy of which,  including the restrictions on Transfer, will be furnished to each holder of shares of Capital Stock of the Corporation on request and without charge.

Instead of the foregoing legend, the certificate may state that the Corporation will furnish a full statement about certain restrictions on transferability to a stockholder on request and without charge.

Section 6.2.10 NO RECOURSE. A Prohibited Owner shall have no claim, cause of action or other recourse whatsoever against the purported transferor of shares of Capital Stock causing the violation of the restrictions set forth in Section 6.2.1(a).

Section 6.3 TRANSFER OF SHARES OF CAPITAL STOCK IN THE CORPORATION.

Section 6.3.1 OWNERSHIP IN TRUST. Upon any purported Transfer or other event described in Section 6.2.1(b) that would result in a transfer of shares of Capital Stock to a Charitable Trust, such shares of Capital Stock shall be deemed to have been transferred to the Charitable Trustee as trustee of a Charitable Trust for the exclusive benefit of one or more Charitable Beneficiaries (except to the extent otherwise provided in Section 6.3.5). Such transfer to the Charitable Trustee shall be deemed to be effective as of the close of business on the Business Day prior to any other purported Transfer or other event that otherwise results in the transfer to the Charitable Trust pursuant to Section 6.2.1(b) (or as of the close of business on the Effective Date if such other purported Transfer or other event occurs on that date). The Charitable Trustee shall be appointed by the Corporation and shall be a Person unaffiliated with the Corporation and any Prohibited Owner. Each Charita ble Beneficiary shall be designated by the Corporation as provided in Section 6.3.7.

Section 6.3.2 STATUS OF SHARES HELD BY THE CHARITABLE TRUSTEE. Shares of Capital Stock held by the Charitable Trustee shall be issued and outstanding shares of Capital Stock of the Corporation.

Section 6.3.3 DIVIDEND AND VOTING RIGHTS. The Charitable Trustee shall have all voting rights and rights to dividends or other distributions with respect to shares of Capital Stock held in the Charitable Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary (except to the extent otherwise provided in Section 6.3.5).

14

Any dividend or other distribution paid prior to the discovery by the Corporation that shares of Capital Stock have been transferred to the Charitable Trustee shall be paid with respect to such shares of Capital Stock to the Charitable Trustee by the Prohibited Owner upon demand and any dividend or other distribution authorized but unpaid shall be paid when due to the Charitable Trustee. Any dividends or distributions so paid over to the Charitable Trustee shall be held in trust for the Charitable Beneficiary. The Prohibited Owner shall have no voting rights with respect to shares of Capital Stock held in the Charitable Trust and, subject to Maryland law, effective as of the date that shares of Capital Stock have been transferred to the Charitable Trustee, the Charitable Trustee shall have the authority (at the Charitable Trustee’s sole discretion) (i) to rescind as void any vote cast by a Prohibited Owner prior to the discovery by the Corporation that shares of Capital Stock have been transferred to the Charitable Trustee and (ii) to recast such vote in accordance with the desires of the Charitable Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Corporation has already taken irreversible corporate action, then the Charitable Trustee shall not have the power to rescind and recast such vote. Notwithstanding the provisions of this Article VI, until the Corporation has received notification that shares of Capital Stock have been transferred into a Charitable Trust, the Corporation shall be entitled to rely on its stock transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies, and otherwise conducting votes of stockholders.

Section 6.3.4 RIGHTS UPON LIQUIDATION. Upon any voluntary or involuntary liquidation, dissolution or winding up of or any distribution of the assets of the Corporation, the Charitable Trustee shall be entitled to receive, ratably with each other holder of shares of Capital Stock of the class or series of shares of Capital Stock that is held in the Charitable Trust, that portion of the assets of the Corporation available for distribution to the holders of such class or series (determined based upon the ratio that the number of shares of such class or series of shares of Capital Stock held by the Charitable Trustee bears to the total number of shares of Capital Stock of such class or series of shares of Capital Stock then outstanding). The Charitable Trustee shall distribute any such assets received in respect of the shares of Capital Stock held in the Charitable Trust in any liquidation, dissolution or wind ing up or distribution of the assets of the Corporation, in accordance with Section 6.3.5.

Section 6.3.5 SALE OF SHARES BY CHARITABLE TRUSTEE.

(a) Within 20 days of receiving notice from the Corporation that shares of Capital Stock have been transferred to the Charitable Trust, the Charitable Trustee of the Charitable Trust shall sell the shares of Capital Stock held in the Charitable Trust (together with the right to receive dividends or other distributions with respect to such shares of Capital Stock as to any shares of Capital S tock transferred to the Charitable Trustee as a result of the operation of Section 6.2.1(b)) to a person, designated by the Charitable Trustee, whose ownership of the shares of Capital Stock will not violate the ownership limitations set forth in Section 6.2.1(a). Upon such sale, the interest of the Charitable Beneficiary in the shares of Capital Stock sold shall terminate and the Charitable Trustee shall distribute the net proceeds of the sale to the Prohibited Owner and to the Charitable Beneficiary as provided in this Section 6.3.5.

15

(b) A Prohibited Owner shall receive the lesser of (1) the net price paid by the Prohibited Owner for the shares of Capital Stock or, if the Prohibited Owner did not give value for the shares of Capital Stock in connection with the event causing the shares of Capital Stock to be held in the Charitable Trust (e.g., in the case of a gift, devise or other such transaction), the Market Price of the shares of Capital Stock on the day of the event causing the shares of Capital Stock to be held in the Charitable Trust, and (2) the net sales proceeds per share received by the Charitable Trustee from the sale or other disposition of the shares of Capital Stock held in the Charitable Trust. Any net sales proceeds in excess of the amount payable to the Prohibited Owne r shall be immediately paid to the Charitable Beneficiary. If, prior to the discovery by the Corporation that shares of Capital Stock have been transferred to the Charitable Trustee, such shares of Capital Stock are sold by a Prohibited Owner, then (i) such shares of Capital Stock shall be deemed to have been sold on behalf of the Charitable Trust and (ii) to the extent that the Prohibited Owner received an amount for such shares of Capital Stock that exceeds the amount that such Prohibited Owner was entitled to receive pursuant to this Section 6.3.5, such excess shall be paid to the Charitable Trustee upon demand.

Section 6.3.6 PURCHASE RIGHT IN STOCK TRANSFERRED TO TRUSTEE. Shares of Capital Stock transferred to the Charitable Trustee shall be deemed to have been offe red for sale to the Corporation, or its designee, at a price per share equal to the lesser of (i) the price per share in the transaction that resulted in such transfer to the Charitable Trust (or, in the case of a devise, gift or other such transaction, the Market Price of the shares of Capital Stock on the day of the event causing the shares of Capital Stock to be held in the Charitable Trust) and (ii) the Market Price on the date the Corporation, or its designee, accepts such offer. The Corporation shall have the right to accept such offer until the Charitable Trustee has sold the shares of Capital Stock held in the Charitable Trust pursuant to Section 6.3.5. Upon such a sale to the Corporation, the interest of the Charitable Beneficiary in the shares of Capital Stock sold shall terminate and the Charitable Trustee shall distribute the net proceeds of the sale to the Prohibited Owner and the Charitable Beneficiary as provided in Section 6.3.5.

Section 6.3.7 DESIGNATION OF CHARITABLE BENEFICIARIES. By written notice to the Charitable Trustee, the Corporation shall designate from time to time one or more nonprofit organizations to be the Charitable Beneficiary of the interest in the Charitable Trust such that (i) shares of Capital Stock held in the Charitable Trust would not violate the restrictions set forth in Section 6.2.1(a) in the hands of such Charitable Beneficiary and (ii) each such organization must be described in Sections 501(c)(3), 170(b)(1)(A) or 170(c)(2) of the Code and contributions to each such organization must be eligible for deduction under each of Sections 170(b)(1)(A), 2055 and 2522 of the Code.

Section 6.4 AMEX TRANSACTIONS. Nothing in this Article VI shall preclude the settlement of any transaction entered into through the facilities of the AMEX or any other national securities exchange or automated inter-dealer quotation system. The fact that the settlement of any transaction takes place shall not negate the effect of any other provision of this Article VI and any transferee in such a transaction shall be subject to all of the provisions and limitations set forth in this Article VI.

16

Section 6.5 ENFORCEMENT. The Corporation is authorized specifically to seek equitable relief, including injunctive relief, to enforce the provisions of this Article VI.

Section 6.6 NON-WAIVER. No delay or failure on the part of the Corporation or the Board of Directors in exercising any right hereunder shall operate as a waiver of any right of the Corporation or the Board of Directors, as the case may be, except to the extent specifically waived in writing.

Section 6.7 ENFORCEABILITY. If any of the restrictions on transfer of shares of Capital Stock contained in this Article VI are determined to be void, invalid or unenforceable by any court of competent jurisdiction, then the Prohibited Owner may be deemed, at the option of the Corporation, to have acted as an agent of the Corporation in acquiring such shares and to hold such shares on behalf of the Corporation.

Section 6.8 AMENDMENTS.
