AND OFFICERS AND CONTROLLING PERSONS.</font></b></p>

<p style="margin:0in 0in 12.0pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company&#146;s
Amended and Restated Articles of Incorporation (the &#147;Articles&#148;) limit the
liability of directors and officers providing that the Company shall indemnify
a person made a party to a proceeding, because that person is or was a director
or officer, against liability incurred in the proceeding, as well as expenses
(including counsel fees), if the person&#146;s conduct was in good faith, and if he
or she reasonably believed, in the case of &#147;official conduct&#148; with the Company,
that his or her conduct was in the Company&#146;s best interests (or at least that
the conduct was not opposed to the Company&#146;s best interests), and, in the case
of any criminal proceeding, that the individual either had reasonable cause to
believe that the conduct was lawful, or had no reasonable cause to believe that
the conduct was unlawful. Indemnification against reasonable expenses incurred
by a director or officer is also required in any case in which that person,
having been made a party to a proceeding because he or she was a director or
officer, has been wholly successful, on the merits or otherwise, in the defense
of such action. These provisions prohibit indemnity if a director or officer is
found liable in a proceeding by the Company (or in a stockholder derivative
action on behalf of the Company) against the director or officer, or in
connection with a proceeding in which the director or officer has been adjudged
liable for having improperly received a personal benefit in his or her capacity
as a director.</font></p>

<p style="margin:0in 0in 12.0pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">A director&#146;s
conduct with respect to an employee benefit plan, for a purpose the director
reasonably believed to be in the interests of the participants in and
beneficiaries of the plan, is conduct which complies with the indemnification
standard set forth in the Articles.</font></p>

<p style="margin:0in 0in 12.0pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">An indemnification
determination may be made by the Company&#146;s Board of Directors by majority vote
of a quorum consisting of directors not at the time parties to the proceeding,
or, if such a quorum cannot be obtained, by majority vote of a committee duly
designated by the Board of Directors (in which deliberations the interested directors
may participate) consisting solely of two or more directors not at the time
parties to the proceeding, or by a determination by special legal counsel
engaged by the Board of Directors. Shareholders, by majority vote (excluding
shares owned by or voted under the control of directors who are at the time
parties to the proceeding) may also order indemnification, as well as a court,
upon application by the director or officer seeking indemnification, if the
court determines that the director or officer is fairly and reasonably entitled
to indemnification in view of all of the relevant circumstances (whether or not
that person met the other standards set forth in the Articles). The Articles
state that it is intended that indemnification be granted to the full extent
permissible under the law, except for matters as to which indemnification would
be in contravention of the laws of the State of Indiana or the United States of
America, whether as a matter of public policy or pursuant to any statutory
provision. The underlying statutory standard for director liability in Indiana
is broad, providing that a director is not liable for any action taken as a
director, or any failure to take any action, unless the director has breached
or failed to perform the duties of the director&#146;s office, and the breach or
failure to perform constitutes willful misconduct or recklessness.</font></p>

<p style="margin:0in 0in 12.0pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company
maintains officers&#146; and directors&#146; liability insurance which insures, subject
to policy limits and retention amounts, against liabilities that officers and
directors of the Company may incur in their respective capacities.</font></p>

<p style="margin:0in 0in 12.0pt;text-autospace:none;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or controlling persons of Registrant pursuant
to the provisions described in Item 6 herein, or otherwise, Registrant has been
advised that in the opinion of the SEC such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person in a successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, Registrant will,
unless in the opinion of its counsel the question has already been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.</font></p>

AND COUNSEL.

ITEM 6. INDEMNIFICATION OF DIRECTORS
AND OFFICERS AND CONTROLLING PERSONS.
The Company's
Amended and Restated Articles of Incorporation (the "Articles") limit the
liability of directors and officers providing that the Company shall indemnify
a person made a party to a proceeding, because that person is or was a director
or officer, against liability incurred in the proceeding, as well as expenses
(including counsel fees), if the person's conduct was in good faith, and if he
or she reasonably believed, in the case of "official conduct" with the Company,
that his or her conduct was in the Company's best interests (or at least that
the conduct was not opposed to the Company's best interests), and, in the case
of any criminal proceeding, that the individual either had reasonable cause to
believe that the conduct was lawful, or had no reasonable cause to believe that
the conduct was unlawful. Indemnification against reasonable expenses incurred
by a director or officer is also required in any case in which that person,
having been made a party to a proceeding because he or she was a director or
officer, has been wholly successful, on the merits or otherwise, in the defense
of such action. These provisions prohibit indemnity if a director or officer is
found liable in a proceeding by the Company (or in a stockholder derivative
action on behalf of the Company) against the director or officer, or in
connection with a proceeding in which the director or officer has been adjudged
liable for having improperly received a personal benefit in his or her capacity
as a director.
A director's
conduct with respect to an employee benefit plan, for a purpose the director
reasonably believed to be in the interests of the participants in and
beneficiaries of the plan, is conduct which complies with the indemnification
standard set forth in the Articles.
An indemnification
determination may be made by the Company's Board of Directors by majority vote
of a quorum consisting of directors not at the time parties to the proceeding,
or, if such a quorum cannot be obtained, by majority vote of a committee duly
designated by the Board of Directors (in which deliberations the interested directors
may participate) consisting solely of two or more directors not at the time
parties to the proceeding, or by a determination by special legal counsel
engaged by the Board of Directors. Shareholders, by majority vote (excluding
shares owned by or voted under the control of directors who are at the time
parties to the proceeding) may also order indemnification, as well as a court,
upon application by the director or officer seeking indemnification, if the
court determines that the director or officer is fairly and reasonably entitled
to indemnification in view of all of the relevant circumstances (whether or not
that person met the other standards set forth in the Articles). The Articles
state that it is intended that indemnification be granted to the full extent
permissible under the law, except for matters as to which indemnification would
be in contravention of the laws of the State of Indiana or the United States of
America, whether as a matter of public policy or pursuant to any statutory
provision. The underlying statutory standard for director liability in Indiana
is broad, providing that a director is not liable for any action taken as a
director, or any failure to take any action, unless the director has breached
or failed to perform the duties of the director's office, and the breach or
failure to perform constitutes willful misconduct or recklessness.
The Company
maintains officers' and directors' liability insurance which insures, subject
to policy limits and retention amounts, against liabilities that officers and
directors of the Company may incur in their respective capacities.
We refer you to
Item 9(c) regarding our undertakings with respect to indemnification for
liabilities arising under the Securities Act.

ITEM 9.  Undertakings.
A.
Undertakings Pursuant to Rule
415.
The undersigned
Registrant hereby undertakes:
(a)
to file, during any period in which
offers or sales are being made, a post-effective amendment to this Registration
Statement:
(i)
to include any prospectus required by
Section 10(a)(3) of the Securities Act of 1933;
(ii)
to reflect in the prospectus any facts or
events arising after the effective date of the Registration Statement (or the
most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the Registration
Statement.  Notwithstanding the
foregoing, any increase or decrease in the volume of securities offered (if the
total dollar value of securities offered would not exceed that which was
registered) and any deviation from the estimated maximum offering range may be
reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b)
if, in the aggregate, the changes in volume and price represent no more than a
20% change in the maximum aggregate offering price set forth in the "Calculation
of Registration Fee" table in the effective Registration Statement;
(iii)
to include any material information with
respect to the plan of distribution not previously disclosed in the Registration
Statement or any material change to such information in the Registration Statement;
provided, however, that the undertakings set forth in clauses (i) and (ii) do
not apply if the information required to be included in a post-effective
amendment by those clauses is contained in reports filed with or furnished to
the SEC by Registrant pursuant to Section 13 or Section 15(d) of the Exchange
Act that are incorporated by reference in the Registration Statement;
(b)
that, for the purpose of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities to
be offered in connection therewith, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof; and
(c)
to remove from registration by means of a
post-effective amendment any of the securities being registered which remain
unsold at the termination of the offering.
B.
Undertaking Regarding Filings
Incorporating Subsequent Exchange Act Documents by Reference.
The undersigned
Registrant hereby undertakes that, for purposes of determining any liabilities
under the Securities Act, each filing of any of Registrant's annual reports
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration
Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.

C.            Undertaking
in Respect of Indemnification
Insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers or controlling persons of Registrant pursuant
to the provisions described in Item 6 herein, or otherwise, Registrant has been
advised that in the opinion of the SEC such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other than
the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person in a successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered hereunder, Registrant will,
unless in the opinion of its counsel the question has already been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
