SHAREHOLDERS AGREEMENT  AFFILIATES INSURANCE COMPANY  This Shareholders Agreement (this Agreement),
dated February 27, 2009, by and among Affiliates Insurance Company, a
company being formed and licensed as an insurance company in the State of
Indiana (the Company), Five Star Quality Care, Inc., a Maryland
corporation (FVE), Hospitality Properties Trust, a Maryland real
estate investment trust (HPT), HRPT Properties Trust, a Maryland real
estate investment trust (HRP), Senior Housing Properties Trust, a
Maryland real estate investment trust (SNH), TravelCenters of America
LLC, a Delaware limited liability company (TA), and Reit Management &
Research LLC, a Delaware limited liability company (RMR, and together
with FVE, HPT, HRP, SNH and TA, the Shareholders).  RECITALS  WHEREAS, the Company has been formed as an
insurance company domiciled in the State of Indiana; and  WHEREAS, the Shareholders have agreed to make
capital contributions to the Company as further detailed in this Agreement and
that as of the funding of those capital contributions as provided in this
Agreement the Shareholders will be the sole shareholders of the Company; and  WHEREAS, the Shareholders and the Company
desire to enter into this Agreement in order to set forth certain agreements
and understandings relating to the business and governance of the Company, the
Shares (as defined herein) held by the Shareholders and certain other matters;  NOW, THEREFORE, in consideration of the
premises, representations, warranties, covenants and agreements contained in this
Agreement and of other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, hereby agree as follows:


ARTICLE I  INVESTMENT IN THE COMPANY; FORMATION AND LICENSING EXPENSES  1.1Purchase
and Sale of Shares.  (a)Concurrently
with the execution and delivery of this Agreement by the Company and the
Shareholders, the Company shall issue and sell to each Shareholder, and each
Shareholder shall purchase from the Company, 100 shares of common stock, par
value of $10.00 per share, of the Company (the Shares) at a purchase
price of $250.00 per Share.  (b)Within
five business days after the Company notifies the Shareholders that the
Department of Insurance of the State of Indiana has notified the Company that
it intends to commence its financial review of the Company, the Company shall
issue and sell to each Shareholder, and each Shareholder shall purchase from
the Company, an additional 19,900 Shares at a purchase price of $250.00 per
Share.  1.2Future
Share Issuances.  No Shareholder shall be obligated to purchase
additional Shares or any other securities of the Company and any future
proposed issuance and sale of Shares or any other securities of the Company
shall be subject to Section 3.2; provided, however, that the parties
hereto acknowledge that the Company may need to seek additional capital in the
future and that it is the intention of the Shareholders that they each may, but
shall not be obligated to, contribute to the Company up to an additional $5
million of capital during the period between the second and fifth anniversaries
of the date of this Agreement.  1.3Formation
and Licensing Expenses.  The Company shall pay for all costs,
fees and expenses in connection with the formation and licensing of the Company
as an Indiana insurance company.  The
Shareholders shall reimburse the Company for such amounts paid by the Company
in equal proportion.  ARTICLE II  BOARD COMPOSITION  2.1Board
Composition.  (a)For
as long as the Shareholders collectively own a majority of the issued and
outstanding Shares, the board of directors of the Company (the Board) shall consist of not less than five nor more
than fifteen members, with the actual number determined in accordance with the
Bylaws of the Company, as in effect from time to time, and subject in all
instances to this Section 2.1.  As
of the date of this Agreement, the Board shall initially consist of thirteen
members.  For so long as required by
applicable Indiana law, at least one member of the Board shall be an Indiana
resident.  Except as otherwise provided
in Section 2.1(c), no Shareholder having a right to designate any director
pursuant to this Article II shall be required to designate an Indiana
resident as a director pursuant to such right; provided, however, that this
sentence shall in no way limit the application of the immediately preceding
sentence.  2


(b)For
so long as a Shareholder (other than RMR) owns not less than 10%of theissued and
outstanding Shares, such Shareholder shall have the right to designate two
directors for election to the Board.  (c)For
so long as RMR owns not less than 10%of theissued and outstanding Shares, RMR shall have the right to
designate three directors for election to the Board.  For so long as RMR has the right to designate
directors pursuant to the immediately preceding sentence, Indiana law requires
the Board to include an Indiana resident as a director of the Company and no
other Shareholder designates an Indiana resident as a director of the Company,
RMR shall designate at least one Indiana resident to be a director.  (d)Each
Shareholder will vote, execute and deliver written consents and take all other
necessary action (including, if necessary, causing the Company to call a
special meeting of shareholders of the Company) in favor of the election of
each director designated by a Shareholder in accordance with this Article II
and otherwise to ensure that the composition of the Board is at all times as
set forth in this Article II.  Each
Shareholder agrees that it will not vote any of its Shares in favor of removal
of any director designated by another Shareholder unless such other Shareholder
shall have consented to such removal in writing.  Each Shareholder agrees to cause to be
called, if necessary, a special meeting of shareholders of the Company and to
vote all the Shares owned by such Shareholder for, or to take all actions in
lieu of any such meeting necessary to cause, the removal of any director
designated by such Shareholder if the Shareholder entitled to designate such
director requests in writing, signed by such Shareholder, such directors
removal for any reason or no reason.  (e)If,
as a result of death, disability, retirement, resignation, removal or
otherwise, there shall exist or occur any vacancy with respect to any director
previously designated by a Shareholder in accordance with such Shareholders
right under this Article II to so designate such director, such
Shareholder shall have the right to designate a replacement director.  Upon such designation, the Shareholders shall
promptly take all action necessary to ensure the election of such replacement
director to fill the unexpired term of the director whom such new director is
replacing, including, if necessary, calling a special meeting of shareholders
of the Company and voting their Shares, or executing any written consent in
lieu thereof, in favor of the election of such director.  ARTICLE III  TRANSFER OF SHARES; PREEMPTIVE RIGHTS; CALL RIGHTS  3.1Transfer
of Shares; No Pledging of Shares.  (a)The
Shareholders may not, directly or indirectly, transfer any Shares, except that
a Shareholder may transfer Shares owned by it to a wholly owned subsidiary of
such Shareholder, to another Shareholder or to a wholly owned subsidiary of
another Shareholder.  Any purported
transfer of Shares in contravention of this Section 3.1 shall be null and
void and of no force or effect.  3


(b)The
Shareholders may not pledge their Shares (other than pledges arising from the
operation of law and not as a result of the Shareholders express granting of a
pledge); provided, however, that any pledge or other lien, charge or encumbrance
which may arise by application of the terms of any agreement, contract,
license, permit or instrument existing on the date hereof (an Existing
Pledge) on a Shareholders Shares shall not be a violation of this Section 3.1(b);
and provided further, however, any transfer which results from exercise of
rights under a permitted lien, charge or encumbrance shall be subject to the
call rights of the Company and the other Shareholders set forth in Section 3.3
to the fullest extent permitted by applicable law and existing contracts as if
such a transfer constitutes a Change of Control.  Any Shareholder whose Shares would be subject
to an Existing Pledge shall use best efforts to cause the pledgee under an
Existing Pledge, prior to any exercise by the pledgee of its rights on the
Shareholders Shares, to take all actions under applicable law which are
required to be taken prior to any such exercise, including obtaining any
necessary approvals from the Indiana Department of Insurance and Indiana Insurance
Commissioner.  3.2Preemptive
Rights.  (a)If,
at any time after the date hereof, the Company wishes to issue any capital
stock of the Company or any other securities convertible into or exchangeable
or exercisable for capital stock of the Company (collectively, New
Securities) to any person or entity (the Subject Purchaser), then
the Company shall first offer the Appropriate Percentage (as defined herein) of
the New Securities (the Allocated Shares) to each Shareholder (each, a
Preemptive Rightholder and collectively, the Preemptive
Rightholders) by sending written notice (the New Issuance Notice)
to each of the Preemptive Rightholders, which New Issuance Notice shall state
the terms of such proposed issuance, including the number of New Securities
proposed to be issued and the proposed purchase price per security of the New
Securities (the Proposed Price). 
Upon delivery of the New Issuance Notice, such offer shall be
irrevocable unless and until the Company shall have terminated the contemplated
issuance of New Securities in its entirety at which time the rights set forth
herein shall be applicable to any proposed issuance subsequent to any such
termination.  For purposes of this Section 3.2,
Appropriate Percentage shall mean that percentage of the New
Securities determined by dividing (i) the total number of Shares then
owned by a Preemptive Rightholder by (ii) the total number of Shares owned
by all the Preemptive Rightholders.  (b)For
a period of 20 days after the giving of the New Issuance Notice pursuant to Section 3.2(a) (the
Initial Preemptive Subscription Period), each of the Preemptive
Rightholders shall have the right to purchase, in whole or in part, the
Allocated Shares offered to such Preemptive Rightholder as determined pursuant
to Section 3.2(a) at a purchase price equal to the Proposed Price and
upon the terms and conditions set forth in the New Issuance Notice.  (c)The
right of each Preemptive Rightholder to purchase the New Securities so offered
under Section 3.2(b) shall be exercisable by delivering written
notice of the exercise thereof, prior to the expiration of the Initial
Preemptive Subscription Period, to the Company, which notice shall state the
amount of New Securities that such Preemptive Rightholder elects to purchase
pursuant to Section 3.2(a).  The
failure of a Preemptive Rightholder to respond prior to the expiration of the
Initial Preemptive Subscription Period shall be deemed to be a waiver of such
Preemptive Rightholders rights under this Agreement solely  4


with respect to its right to purchase the New
Securities referenced in the New Issuance Notice; provided that each Preemptive
Rightholder may waive its rights under Section 3.2(b) prior to the
expiration of Initial Preemptive Subscription Period by giving written notice
of such waiver to the Company.  (d)If as of the expiration of the
Initial Preemptive Subscription Period, some but not all of the Preemptive
Rightholders have exercised their right to purchase the full amount of New
Securities to which they are entitled to purchase pursuant to Sections 3.2(b) and
(c) (any such Preemptive Rightholder which has exercised in full its
rights to purchase such New Securities, a Fully Exercising Preemptive Rightholder),
the Fully Exercising Preemptive Rightholders shall have the right to purchase,
in whole or in part, their Oversubscription Appropriate Percentage (as defined
herein) of the New Securities which the Preemptive Rightholders did not
exercise their right to purchase pursuant to Sections 3.2(b) and (c) (the
Undersubscribed Shares) at a purchase price equal to the Proposed
Price and upon the terms and conditions set forth in the New Issuance
Notice.  The right of the Fully
Exercising Preemptive Rightholders to purchase the Undersubscribed Shares may
be exercised for a period of ten days following the earlier of the expiration
of the Initial Preemptive Subscription Period or the date on which notice is
given by the Company to such Fully Exercising Preemptive Rightholders that all
the Preemptive Rightholders have either exercised their right to purchase the
New Securities pursuant to Sections 3.2(b) and (c) or waived their
rights to purchase any of such New Securities pursuant to Section 3.2(c) (the
Oversubscription Period).  For
purposes of this Section 3.2, Oversubscription Appropriate Percentage
shall mean that percentage of the Undersubscribed Shares determined by dividing
(i) the total number of Shares then owned by a Fully Exercising Preemptive
Rightholder by (ii) the total number of Shares owned by all the Fully
Exercising Preemptive Rightholders.  (e)The right of each Fully Exercising
Preemptive Rightholder to purchase Undersubscribed Shares pursuant to Section 3.2(d) shall
be exercisable by delivering written notice of the exercise thereof, prior to
the expiration of the Oversubscription Period, to the Company, which notice
shall state the amount of Undersubscribed Shares that such Fully Exercising
Preemptive Rightholder elects to purchase pursuant to Section 3.2(d).  The failure of a Fully Exercising Preemptive
Rightholder to respond prior to the expiration of the Oversubscription Period
shall be deemed to be a waiver of such Fully Exercising Preemptive
Rightholders rights under this Agreement solely with respect to its right to
purchase the Undersubscribed Shares included in the New Securities referenced
in the New Issuance Notice; provided that each Fully Exercising Preemptive
Rightholder may waive its rights under Section 3.2(d) prior to the
expiration of Oversubscription Period by giving written notice of such waiver
to the Company.  (f)The closing of the purchase of New
Securities subscribed for by the Preemptive Rightholders, including the Fully
Exercising Preemptive Rightholders, pursuant to this Section 3.2 shall be
held at such time and place as the parties to the transaction may reasonably
agree.  At such closing, the New
Securities subscribed for shall be issued by the Company free and clear of all
liens, charges or encumbrances (other than those arising hereunder and those
attributable to actions by the purchasers thereof).  Each Preemptive Rightholder, including each
Fully Exercising Preemptive Rightholder, purchasing the New Securities shall deliver
at the closing payment in full in immediately available funds for the New
Securities  5


purchased by it.  At such closing, all of the parties to the
transaction shall execute such additional documents as are otherwise necessary,
appropriate or customary for similar financing transactions.  If any Preemptive Rightholder, including any
Fully Exercising Preemptive Rightholder, fails to purchase any New Securities
for which it exercised its right to purchase pursuant to Sections 3.2(b) and
(c) or 3.2(d) and (e), such New Securities may be purchased by the
Fully Exercising Preemptive Rightholders which did purchase all the New
Securities for which they exercised their rights to purchase pursuant to
Sections 3.2(b), (c), (d) and (e) in the same manner provided in this
Section 3.2 with respect to Undersubscribed Shares and the resulting
Oversubscription Period with respect to such right to purchase shall be an
Oversubscription Period for all instances such term is used in this Section 3.2.  Notwithstanding the preceding sentence, the
obligations and liability of any Preemptive Rightholder, including any Fully
Exercising Preemptive Rightholder, which fails to purchase any New Securities
for which it exercised its right to purchase pursuant to Sections 3.2(b) and
(c) or 3.2(d) and (e) shall not be relieved as a result of any
Fully Exercising Preemptive Rightholders right to purchase, or any actual
purchase by any Fully Exercising Preemptive Rightholder of, any such New
Securities.  (g)Following the expiration of the
later of the Initial Preemptive Subscription Period and, if applicable, the
Oversubscription Period, if the Preemptive Rightholders, including any Fully
Exercising Preemptive Rightholders, did not exercise their right to purchase
any of the New Securities, including the Undersubscribed Shares, which were
originally the subject of the New Issuance Notice, then the Company may sell
the remaining New Securities to the Subject Purchaser on terms and conditions
that are no more favorable to the Subject Purchaser than those set forth in the
New Issuance Notice; provided, however, that such sale is bona fide and made
pursuant to a contract entered into between the Company and the Subject
Purchaser and that such sale is consummated by not later than 90 days following
the earlier to occur of (i) receipt by the Company of written waivers
pursuant to Section 3.2(c) from all the Preemptive Rightholders of
their rights to purchase the Appropriate Percentage of New Securities and, if
applicable, written waivers pursuant to Section 3.2(e) from all the
Fully Exercising Preemptive Rightholders of their rights to purchase the
Oversubscription Appropriate Percentage of New Securities, and (ii) the
expiration of the Oversubscription Period, if applicable, and if not
applicable, the expiration of the Initial Preemptive Subscription Period.  If the sale of any of the New Securities is
not consummated by the expiration of such 90 day period, then the preemptive
rights afforded to the Shareholders under this Section 3.2 shall again
become effective, and no issuance and sale of New Securities may be made
thereafter by the Company without again offering the same in accordance with
this Section 3.2.  3.3Change of Control
Call Option.  (a)By not later than five days following
a Change of Control (as defined herein or in Section 3.1(b)) of any
Shareholder, such Shareholder shall give the Company and each other Shareholder
notice of such Change of Control and shall disclose the number of Shares and
any other securities of the Company which were owned by the Shareholder as of
immediately prior to such Change of Control of such Shareholder (the Change
of Control Securities).  If the
Shareholder fails to give the notice required by the preceding sentence by the
time required thereby, and another Shareholder or the Company is or becomes
aware that such Shareholder underwent a Change of Control, then (i) if it
is a  6


Shareholder that is or becomes aware of such
Change of Control, that Shareholder shall reasonably promptly inform the
Company of such Change of Control and upon the Company being of the reasonable
belief that such a Change of Control has occurred, the Company shall reasonably
promptly provide the notice to the Shareholders that such Shareholder which
underwent the Change of Control failed to provide, or (ii) if it is the
Company that is or becomes aware of such Change of Control, the Company shall
reasonably promptly provide the notice that such Shareholder which underwent
the Change of Control failed to provide. 
Any liability of a Shareholder which undergoes a Change of Control for
failure to give the notice required by the first sentence of this Section 3.3(a) shall
not be relieved as a result of the Company or any other Shareholder being
obligated to give, or giving, the notice required by the second sentence of
this Section 3.3(a).  (b)For a period of 20 days following
the receipt of a notice given pursuant to Section 3.3(a), the Company
shall have the right to purchase from such Shareholder (or its successor, as
applicable), in whole or in part, the Change of Control Securities.  The purchase price for the Change of Control
Securities shall be the book value, as determined in accordance with the
statutory accounting principles applicable to the Company, of the Change of
Control Securities as of the time such Shareholder underwent the Change of
Control (the Call Option Purchase Price).  To exercise its right to purchase the Change
of Control Securities, the Company shall deliver written notice of such
exercise to the Shareholder which underwent the Change of Control and the other
Shareholders prior to the expiration of such 20 day call exercise period.  The closing for any such exercised call
option shall occur on the fifth business day (or such longer period as may be
required by applicable law or in order to obtain applicable regulatory
approval) following receipt of the Companys notice of exercise of its call
option by the Shareholder which underwent the Change of Control, or on such
other date as may be agreed by the Company and such Shareholder.  At its option, the Company may pay in cash
the entire amount of the Call Option Purchase Price at such closing or it may
elect to defer any amount of the Call Option Purchase Price.  Any amounts so deferred shall bear interest
at the Deferred Interest Rate (as defined herein).  The Company may pay any such deferred amounts
and accrued interest thereon at any time and from time to time; provided,
however, that all such deferred amounts and accrued but unpaid interest, shall
be due and payable on the fifth anniversary of the closing of the applicable
call option exercise.  (c)Shareholders other than the
Shareholder which underwent the Change of Control shall have the right to
purchase, in whole or in part, any Change of Control Securities not elected to
be purchased by the Company pursuant to Section 3.3(b) at a price
equal to the Call Option Purchase Price. 
To exercise its right to purchase the Change of Control Securities, the
applicable Shareholder shall deliver written notice of such exercise to the
Shareholder which underwent the Change of Control, the Company and the other
Shareholders by not later than the 20 days following the earlier of (i) the
expiration of the 20 day period during which the Company has the right to
exercise its call option for the Change of Control Securities pursuant to Section 3.3(b) and
(ii) the date the Company waives its right to purchase such Change of
Control Securities and has given notice of the same to all the Shareholders
(such deadline for exercising a right to purchase Change of Control Securities
referred to as the Call Option Exercise Deadline).  The notice of exercise shall indicate the
number of Change of Control Securities that the Shareholder seeks to
purchase.  If the aggregate number of
Change of Control Securities sought to be purchased by the exercising
Shareholders (determined by adding  7


all the eligible securities each Shareholder
states it seeks to purchase in its notice of exercise) exceeds the actual
number of Change of Control Securities eligible for purchase, the number of
Change of Control Securities which may be purchased by a particular applicable
Shareholder shall be reduced by an amount equal to the product of the aggregate
number of such excess Change of Control Securities sought to be purchased by
all the exercising Shareholders multiplied by the quotient of (x) the
number of Shares owned by all eligible Shareholders which are exercising their
call option rights minus the number of Shares owned by the particular
applicable exercising Shareholder divided by (y) the number of
Shares owned by all eligible Shareholders which are exercising their call
option rights, with any such result rounded up or down to the nearest whole
share as reasonably determined by the Company. 
The closing of any such exercised call option shall occur on the fifth
business day (or such longer period as may be required by applicable law or in
order to obtain applicable regulatory approval) following the Call Option
Exercise Deadline, or on such other date as may be agreed by the exercising
Shareholder, the Company and the Shareholder which underwent the Change of
Control.  At its option, the exercising
Shareholder may pay in cash the entire amount of the Call Option Purchase Price
at such closing or it may elect to defer any amount of the Call Option Purchase
Price.  Any amounts so deferred shall
bear interest at the Deferred Interest Rate. 
The exercising Shareholder may pay any such deferred amounts and accrued
interest thereon at any time and from time to time; provided, however, that all
such deferred amounts and accrued but unpaid interest, shall be due and payable
on the fifth anniversary of the closing of the applicable call option exercise.  (d)Definitions.

the preemptive rights and the change of control call options created by
Sections 3.1, 3.2 and 3.3 of this Article III shall not apply to any sale
of Shares by the Company, or by any Shareholder or Shareholders, if the Shares
are sold to an entity which is managed by RMR that purchases insurance from the
Company, provided that any such sale does not reduce the ownership of any Shareholder
to less than ten percent (10%) of the Companys outstanding voting Shares.  ARTICLE IV  SPECIAL SHAREHOLDER APPROVAL REQUIREMENTS.  4.1Special

Agreement shall control.  5.2Reports and Information Access.  For
so long as a Shareholder owns not less than 10% of all the issued and
outstanding Shares, the Company shall provide periodically, through the
director(s) designated by such Shareholder under Section 2.1, to the
Shareholder financial information regarding the Company and its operations and
the Company shall permit the Shareholder and its representatives reasonable
access to the financial reports and records of the Company so that the
Shareholder may comply with its financial reporting and tax reporting
obligations and procedures, and disclosure obligations under the federal
securities laws and other applicable laws.  5.3Compliance with Laws.  The
Company shall comply in all material respects with all applicable laws
governing its business and operations. 
Except as provided in Section 5.7, if a Shareholder, by virtue of
such Shareholders ownership interest in the Company or actions taken by the
Shareholder affecting the Company, triggers the application of any requirement
or regulation of any federal, state, municipal or other governmental or
regulatory body on the Company or any subsidiary of the Company or any of their
respective businesses, assets or operations, including any obligations to make
any filing with or otherwise notifying or obtaining the consent, approval or
other action of any federal, state, municipal or other governmental or regulatory
body, such Shareholder shall promptly take all actions necessary and fully
cooperate with the Company to ensure that such requirements or regulations are
satisfied without restricting, imposing additional obligations on or in any way
limiting the business, assets,  10


operations or prospects of
the Company or any subsidiary of the Company. 
Each Shareholder shall use best efforts to cause its shareholders,
directors (or analogous position), nominees for director (or analogous
position), officers, employees and agents to comply with any applicable laws
impacting the Company or any of its subsidiaries or their respective
businesses, assets or operations.  5.4Cooperation; Further Assurances.  (a)The Shareholders shall cooperate with each
other and the Company in furtherance of the Companys underwriting of insurance
policies and coverage with respect to the Shareholders and their respective
businesses, assets and properties as well as in furtherance of the development
and execution of the Companys business as an insurer.  The Shareholders intend to transition (but
shall not be obligated to do so) their applicable insurance policies and
coverage to the Company so that the Company or its third party agents or
contracting parties shall become the underwriters of such current and future
policies and coverage.  (b)Each of the parties shall execute such
documents and perform such further acts (including obtaining any consents,
exemptions, authorizations or other actions by, or giving any notices to, or
making any filings with, any governmental authority) as may be reasonably
required or desirable to carry out or to perform the provisions of this
Agreement or the transactions contemplated hereby, including in connection with
any subsequent exercise by a party of a right afforded hereunder to such party.  5.5Confidentiality. 
Except as may be required by applicable law or the rules of any
national securities exchange upon which a partys shares are listed for
trading, none of the parties hereto shall make any disclosure concerning this
Agreement, the transactions contemplated hereby or the business, operations and
financial affairs of the Company without prior approval by the other parties
hereto; provided, however, that nothing in this Agreement shall restrict any of
the parties from disclosing information (a) that is already publicly
available, (b) that was known to such party on a non-confidential basis
prior to any relevant disclosure, (c) that may be required or appropriate
in response to any summons or subpoena or in connection with any litigation,
provided that such party will use reasonable efforts to notify the other party
in advance of such disclosure so as to permit the other party to seek a protective
order or otherwise contest such disclosure, and such party will use reasonable
efforts to cooperate, at the expense of the other party, with the other party
in pursuing any such protective order, (d) to the extent that such party
reasonably believes it appropriate in order to protect its investment in its
Shares in order to comply with any applicable law, (e) to such partys
officers, directors, trustees, advisors, employees, auditors or counsel or
(f) as warranted pursuant to the parties disclosure obligations under
federal securities laws.  5.6Required Regulatory Approvals. 
Certain transactions required, permitted or otherwise contemplated by
this Agreement may under certain circumstances require prior filings with and
approvals, or non-disapprovals, from the Indiana Department of Insurance or the
Indiana Insurance Commissioner.  Such
transactions include: (a) issuance or purchase of any additional capital
stock of the Company or other securities convertible into or exchangeable or
exercisable for capital stock of the Company pursuant to Sections 1.2 or 3.4;
(b) transfer of Shares to a wholly owned subsidiary of a Shareholder, to
another Shareholder or to a wholly  11


owned subsidiary of another
Shareholder pursuant to Sections 3.1(a) or 3.4; (c) exercise of
preemptive rights by a Shareholder pursuant to Section 3.2; and
(d) exercise of call rights by the Company or a Shareholder pursuant to
Section 3.3 (including pursuant to the two provisos in Section 3.1(b)).  Notwithstanding anything to the contrary
contained in this Agreement, any such transactions requiring filings with and
approvals, or non-disapprovals, from the Indiana Department of Insurance or the
Indiana Insurance Commissioner shall not, to the extent within the control of a
party hereto, be entered into or consummated unless and until the required
filings have been made and the required approvals (or non-disapprovals) have
been obtained, and to the extent not within the control of an applicable party
hereto, such party shall use best efforts to cause such transactions not to be
entered into or consummated unless and until the required filings have been
made and the required approvals (or non-disapprovals) have been obtained.  5.7REIT Matters.  At
the request of any Shareholder that intends (for itself or for any of its
affiliates) to qualify and be taxed as a real estate investment trust under the
Internal Revenue Code of 1986, as amended (the Code), the Company
shall (a) join with such Shareholder (or, as applicable, such
Shareholders affiliate) in making a taxable REIT subsidiary election under
Section 856(l) of the Code and (b) otherwise reasonably
cooperate with any request of such Shareholder (or its affiliate) pertaining to
such real estate investment trust status or taxation under the Code.  ARTICLE VI  REPRESENTATIONS

this Agreement.  (b)Binding Effect.  This
Agreement has been duly executed and delivered by the Shareholder and
constitutes the legal, valid and binding obligations of the Shareholder,
enforceable against it in accordance with its terms, except as enforceability

decrees applicable to, or binding upon, the Shareholder or any of its assets or
properties.  (f)Purchase Entirely for Own Account.  The Shares are being acquired for investment
for the Shareholders own account, not as a nominee or agent, and not with a view
to the resale or distribution of any part thereof, and the Shareholder has no
present intention of selling, granting any participation with respect to or
otherwise distributing the Shares.  The
Shareholder does not have any contract, undertaking, agreement or arrangement
with any person or entity to sell or transfer to any person or entity, or grant
participation rights to any person or entity with respect to, any of the
Shares.  (g)Disclosure of Information.  The Shareholder has received all the information

the merits and risks of the investment in the Shares to be purchased hereunder.  (i)Restricted Securities.    The Shareholder understands that the

of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provision of this Agreement.  8.9Severability.  If any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
