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.  (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  3


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.  (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, for any of the Original Shareholders, on the Original
Date, and for GOV, 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  4


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 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  5


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
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  6


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 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  7


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 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.  For
purposes of this Section 3.3, the following terms have the meanings set
forth below:  (i)    Change of Control means (A) the

portion of the assets (including capital stock or other equity interests) or

adjustment date being treated as an applicable closing date for purposes of
determining the adjusted rate in accordance  9

be unpaid.  3.4Permitted New Issuance of Shares.  The prohibition on transfer of

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, 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  11


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 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.  12

that intends (for itself or for any of its affiliates) to qualify and be taxed

Shareholder (or, as applicable, such Shareholders affiliate) in making a taxable

pertaining to such real estate investment trust status or taxation under the

failure or delay on the part of any party in exercising any right, power or

of any remedies that may be available to each party at law, in equity or

amendment, supplement or modification of or to any provision of this Agreement,
shall be effective upon the written agreement of the Company and the
Shareholders owning not less than 75% of all Shares owned by the Shareholders;
provided, however, that any amendment, supplement or modification of Article I
or Article II shall require the approval of any Shareholder which may be

any number of counterparts and by the parties hereto in separate counterparts,
each of which when so executed  18


shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.  8.5Headings.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.  8.6Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Indiana without regard to
the conflicts of laws rules thereof, which would require the application
of the laws of another jurisdiction.  8.7Dispute Resolution  (a)        Any
disputes, claims or controversies between the parties (i) arising out of
or relating to this Agreement, the Company, its business, assets or operations
or any insurance policies or coverage underwritten by the Company or any of its
third party agents in furtherance of the Companys insurance business or (ii) brought
by or on behalf of any shareholder of the Company (which, for purposes of this Section 8.7,
shall mean any shareholder of record or any beneficial owner of shares of the
Company, or any former shareholder of record or beneficial owner of shares of
the Company), either on his, her or its own behalf, on behalf of the Company or
on behalf of any series or class of shares of the Company or shareholders of
the Company against the Company or any director, officer, manager (including
RMR or its successor), agent or employee of the Company, including disputes,
claims or controversies relating to the meaning, interpretation, effect,
validity, performance or enforcement of this Agreement or the articles of
incorporation or bylaws of the Company (all of which are referred to as Disputes),
or relating in any way to such a Dispute or Disputes shall, on the demand of
any party to such Dispute, be resolved through binding and final arbitration in
accordance with the Commercial Arbitration Rules (the Rules) of
the American Arbitration Association (AAA) then in effect, except as
those Rules may be modified in this Section 8.7.  For the
avoidance of doubt, and not as a limitation, Disputes are intended to include
derivative actions against directors, officers or managers of the Company and
class actions by a shareholder against those individuals or entities and the
Company.  For the avoidance of doubt, a Dispute shall include a Dispute
made derivatively on behalf of one party against another party.  (b)        There
shall be three arbitrators.  If there are only two parties to the Dispute,
each party shall select one arbitrator within 15 days after receipt by
respondent of a copy of the demand for arbitration.  Such arbitrators may
be affiliated or interested persons of such parties.  If either party
fails to timely select an arbitrator, the other party to the Dispute shall
select the second arbitrator who shall be neutral and impartial and shall not
be affiliated with or an interested person of either party.  If there are
more than two parties to the Dispute, all claimants, on the one hand, and all
respondents, on the other hand, shall each select, by the vote of a majority of
the claimants or the respondents, as the case may be, one arbitrator. Such
arbitrators may be affiliated or interested persons of the claimants or the
respondents, as the case may be.  If either all claimants or all
respondents fail to timely select an arbitrator then such arbitrator (who shall
be neutral, impartial and unaffiliated with any party) shall be appointed by
the AAA.  The two arbitrators so appointed shall jointly appoint the third
and presiding arbitrator (who shall be neutral, impartial and unaffiliated with
any party) within 15 days of the appointment of the second arbitrator.  If
the third arbitrator has not been appointed within the  19


time limit specified
herein, then the AAA shall provide a list of proposed arbitrators in accordance
with the Rules, and the arbitrator shall be appointed by the AAA in accordance
with a listing, striking and ranking procedure, with each party having a
limited number of strikes, excluding strikes for cause.  (c)        The
place of arbitration shall be Indianapolis, Indiana unless otherwise agreed by
the parties.  (d)        There
shall be only limited documentary discovery of documents directly related to
the issues in dispute, as may be ordered by the arbitrators.  (e)        In
rendering an award or decision (the Award), the arbitrators shall be
required to follow the laws of the State of Indiana.  Any arbitration
proceedings or Award rendered hereunder and the validity, effect and
interpretation of this arbitration agreement shall be governed by the Federal
Arbitration Act, 9 U.S.C. §1 et seq.  The Award shall be in writing and
may, but shall not be required to, briefly state the findings of fact and conclusions
of law on which it is based.  (f)         Except
to the extent otherwise agreed by the parties, each party involved in a Dispute
shall bear its own costs and expenses (including attorneys fees), and the
arbitrators shall not render an award that would include shifting of any such
costs or expenses (including attorneys fees) or, in a derivative case or class
action, award any portion of the Companys award to the claimant or the
claimants attorneys.  Each party (or, if there are more than two parties
to the Dispute, all claimants, on the one hand, and all respondents, on the
other hand, respectively) shall bear the costs and expenses of its (or their)
selected arbitrator and the parties (or, if there are more than two parties to
the Dispute, all claimants, on the one hand, and all respondents, on the other
hand) shall equally bear the costs and expenses of the third appointed
arbitrator.  (g)        An
Award shall be final and binding upon the parties thereto and shall be the sole
and exclusive remedy between such parties relating to the Dispute, including
any claims, counterclaims, issues or accounting presented to the
arbitrators.  Judgment upon the Award may be entered in any court having
jurisdiction.  To the fullest extent permitted by law, no application or appeal
to any court of competent jurisdiction may be made in connection with any
question of law arising in the course of arbitration or with respect to any
award made except for actions relating to enforcement of this agreement to
arbitrate or any arbitral award issued hereunder and except for actions seeking
interim or other provisional relief in aid of arbitration proceedings in any
court of competent jurisdiction.  (h)        Any
monetary award shall be made and payable in U.S. dollars free of any tax,
deduction or offset.  Each party against which the Award assesses a
monetary obligation shall pay that obligation on or before the 30thday following the date of the Award
or such other date as the Award may provide.  (i)         This Section 8.7
is intended to benefit and be enforceable by the shareholders, directors,
officers, managers (including RMR or its successor), agents or employees of the
Company and the Company and shall be binding on the shareholders of the  20


Company and the Company,
as applicable, and shall be in addition to, and not in substitution for, any
other rights to indemnification or contribution that such individuals or
entities may have by contract or otherwise.  8.8Interpretation and Construction.  (a)        The
words hereof, herein, hereby and hereunder and words of similar import,
when used in this Agreement, shall refer to this Agreement as a whole and not
to any particular provision of this Agreement.  (b)        Unless
the context otherwise requires, references to sections, subsections or Articles
refer to sections, subsections or Articles of this Agreement.  (c)        Terms
defined in the singular shall have a comparable meaning when used in the
plural, and vice versa.  (d)        The
words include and including and words of similar import shall be deemed to
be followed by the words without limitation.  (e)        Words
importing gender include both genders.  (f)         Any
agreement, instrument or statute defined or referred to herein or in any
agreement or instrument that is referred to herein means such agreement,
instrument or statute as from time to time amended, modified or supplemented,
including (in the case of agreements or instruments) by waiver or consent and
(in the case of statutes) by succession of comparable successor statutes and
references to all attachments thereto and instruments incorporated
therein.  In addition, references to any statute are to that statute and
to the rules and regulations promulgated thereunder.  (g)        The
parties hereto have participated jointly in the negotiation and drafting of
this Agreement and, in the event an ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as jointly drafted by
the parties hereto and no presumption or burden 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, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way
impaired, unless the provisions held invalid, illegal or unenforceable shall
substantially impair the benefits of the remaining provisions hereof.  8.10Entire Agreement.  This Agreement and the GOV
Subscription Agreement constitute the entire agreement, and supersede all prior
agreements and understandings, both written and oral, among the parties with
respect to the subject matter of this Agreement.  21
