INDEMNIFICATION OF
DIRECTORS AND OFFICERS
Under Virginia law, to the extent provided in the articles of
incorporation or an amendment to the bylaws approved by shareholders, a
corporation may eliminate a director's or an officer's personal liability for
monetary damages in any proceeding brought by or in the right of a corporation
or brought by or on behalf of shareholders, except for liability resulting from
such director's or officer's wilful misconduct or a knowing violation of
criminal law or of any federal or state securities law.
Our
bylaws provide that the directors and officers shall not be liable for monetary
damages to us or our shareholders with respect to any transaction, occurrence or
course of conduct, except for liability resulting from such director's or
officer's wilful misconduct or a knowing violation of the criminal law or any
federal or state securities law.
Under
Virginia law, a corporation may indemnify any person made a party to a
proceeding because he or she is or was a director or officer against liability
incurred in the proceeding if he or she acted in good faith and in a manner he
or she believed to be in or not opposed to the best interests of the
corporation, and in the case of any criminal proceeding, he or she had no
reasonable cause to believe his or her conduct was unlawful, except that a
corporation may not indemnify a director or officer in connection
with:
·
a
      proceeding by or in the right of the corporation, except for reasonable
      expenses incurred in connection with the proceeding if he or she meets the
      standard of conduct specified in this paragraph;
  or
·
any
      other proceeding charging improper personal benefit to him or her, whether
      or not involving action in his or her official capacity, in which he or
      she was adjudged liable on the basis that personal benefit was improperly
      received by him or her.
Our
bylaws provide that we shall indemnify any director, officer or employee of
Olin, or any person who, at our request, serves or has served in any such
capacity with another corporation, partnership, joint venture, trust, employee
benefit plan, or other enterprise, in each case against any and all liability
and reasonable expense that may be incurred by him or her in connection with or
resulting from any claim, action or proceeding (whether brought in the right of
Olin or any such other corporation, entity, plan or otherwise), civil or
criminal, in which he or she may become involved, as a party or otherwise, by
reason of his or her being or having been a director, officer or employee of
Olin, or such other corporation, entity or plan while serving at our request,
whether or not he or she continues to be such at the time such liability or
expense shall have been incurred, unless such person engaged in wilful
misconduct or a knowing violation of the criminal law.
Virginia
law provides that any indemnification for a director or officer, unless ordered
by a court, is subject to a determination that the director or officer has met
the applicable standard of conduct. The determination will be made:
3
·
if
      there are two or more disinterested directors, by the board of directors
      by a majority vote of all of the disinterested directors, a majority of
      whom shall for such purpose constitute a quorum, or by a majority of the
      members of a committee of two or more disinterested directors appointed by
      such a vote,
·
by
      special legal counsel (1) selected  in the manner described
      in the first bullet point above or (2) if there are fewer than two
      disinterested directors, selected by the board of directors, in which
      selection directors who do not qualify as disinterested directors may
      participate, or
·
by
      the shareholders, but shares owned by or voted under the control of a
      director who does not qualify as a disinterested director may not be voted
      on the determination.
Our
bylaws provide that any indemnification of a director, officer or employee shall
be made unless:
·
the
      board of directors, acting by a majority vote of those directors who were
      directors at the time of the occurrence giving rise to the claim for
      indemnification and who are not at the time parties to such claim
      (provided that there are at least five such directors), finds that the
      person seeking indemnification has not met the standards of conduct set
      forth in our bylaws or
·
if
      there are not five such directors, our principal Virginia legal counsel,
      as last designated by the board of directors before the occurrence of the
      event giving rise to the claim for indemnification, or in the event such
      Virginia legal counsel is unwilling to serve, then Virginia legal counsel
      mutually acceptable to us and the person seeking indemnification, delivers
      to us its written legal advice that, in such counsel's opinion, the person
      seeking indemnification has not met the standards of conduct set forth in
      our bylaws.
Under
Virginia law, a corporation may advance expenses before the final disposition of
a proceeding if:
·
the
      director or officer furnishes a written statement of his good faith belief
      that he or she has met the proper standard of conduct,
  and
·
he
      or she undertakes in writing to repay the amount advanced if it is
      ultimately determined that the director or officer did not meet the proper
      standard of conduct.
Under
Virginia law, to the extent that a director or officer has been successful on
the merits or otherwise in defense of the proceeding, the director or officer
must be indemnified against reasonable expenses incurred by him or her in
connection with that proceeding.
4
Under our
bylaws, we are required to advance expenses incurred by a director, officer or
employee prior to the final disposition of the proceeding if the director,
officer or employee furnishes to us an undertaking to repay the amount of the
expenses advanced in the event it is ultimately determined that he or she is not
entitled to indemnification under our bylaws. Our bylaws do not require that the
director, officer or employee furnish any security for such undertaking and
provide that such undertaking shall be accepted without reference to the
director's, officer's or employee's ability to make repayment. We may refrain
from, or suspend, payment of expenses if our board of directors or Virginia
legal counsel determines that the director, officer or employee has not met the
standards of conduct set forth in our bylaws.
Virginia
law gives a corporation the power to purchase and maintain insurance on behalf
of any director or officer against any liability asserted against, and incurred
in his or her capacity as, a director or officer, whether or not the corporation
would have the power to indemnify the director or officer against this liability
under Virginia law.

UNDERTAKINGS
(a)
The
undersigned Registrant hereby undertakes:
1.
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
      volume of securities offered (if the total dollar value of securities
      offered would not exceed that which was registered) and any deviation from
      the low or high end of the estimated maximum offering range may be
      reflected in the form of prospectus filed with the Commission 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;
and
5
(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 paragraphs (i) and (ii) above do not apply if the information
required to be included in a post-effective amendment by those paragraphs is
contained in reports filed with or furnished to the Commission by the Registrant
pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934
that are incorporated by reference in the registration statement.
2.
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 offered therein, and the
      offering of such securities at that time shall be deemed to be the initial
      bona fide offering thereof.
3.
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)
The
undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) 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)
Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the provisions referred to under Item 6, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 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 of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has 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 of 1933 and will be governed by the final adjudication of such
issue.
