Item 6. Indemnification of Directors and Officers

The Company is incorporated in Virginia. Under Virginia law, to the extent provided in its articles of incorporation or its shareholder-approved bylaws, 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 willful misconduct or a knowing violation of criminal law or of any federal or state securities law.

The bylaws of the Company, as amended from time to time (the “Olin bylaws”), provide that the directors and officers will not be liable for monetary damages to the Company or the Company’s shareholders with respect to any transaction, occurrence or course of conduct, except for liability resulting from such director’s or officer’s willful 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 the best interests of the corporation (or not opposed to such interests if he or she is acting outside his or her official capacity with 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. Virginia law also provides that a corporation has the power to make any further indemnity, including indemnity with respect to a proceeding by or in the right of the

corporation, and may make additional provisions for advances and reimbursement of expenses, if authorized by its articles of incorporation or shareholder-approved bylaws or resolution, except indemnity against willful misconduct or a knowing violation of criminal law.

The Olin bylaws provide that we shall indemnify any of our directors, officers or employees, or any person who, at its 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 the Company 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 the Company, 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 willful 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 relevant standard of conduct. The determination will be made:

•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 majority vote of the members of a committee, consisting of two or more disinterested directors appointed by such a vote;

•by special legal counsel (a) selected in the manner described in the first bullet point above or (b) 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.

The Olin bylaws require that the Company indemnify a director, officer or employee unless:

•the Company’s board of directors (the “Olin board”), 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 the Olin bylaws; or

•if there are not five such directors, its principal Virginia legal counsel, as last designated by the Olin board 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 the Company and the person seeking indemnification, delivers to the Company its written legal advice that, in such counsel’s opinion, the person seeking indemnification has not met the standards of conduct set forth in the Olin bylaws.

Under Virginia law, a corporation may advance expenses before the final disposition of a proceeding if the director or officer undertakes in writing to repay the amount advanced if it is ultimately determined that the director or officer did not meet the relevant standard of conduct.

Under Virginia law, unless limited by a corporation’s articles of incorporation, 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 expenses incurred by him or her in connection with that proceeding.

Under the Olin bylaws, the Company is 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 the Company 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 the Olin bylaws. The Olin bylaws do not require that the director, officer or employee furnish any security for such undertaking and provide that such undertaking will be accepted without reference to the director’s, officer’s or employee’s ability to make repayment. The Company may refrain from, or suspend, payment of expenses if the Olin board or Virginia legal counsel determines that the director, officer or employee has not met the standards of conduct set forth in the Olin bylaws.

Virginia law permits a corporation 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. The Company carries insurance on behalf of its directors and officers.
