If a claim under Section 5.1 hereof is not paid in full by the corporation within 30 days after a written claim therefor has been received by the corporation, the claimant may bring suit against the corporation to recover the unpaid amount of the claim.

Neither the failure of the corporation (including the Board of Directors, independent legal counsel, or the shareholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct, nor an actual determination by the corporation (including the Board of Directors, independent legal counsel, or the shareholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct. Section 5.4. Contractual Rights. The right to be indemnified under Section 5.1 (but not Section 5.2), including any right to the reimbursement or advancement of expenses pursuant thereto, (i) is a contract right based upon good and valuable consideration, pursuant to which the person entitled thereto may bring suit as if the provisions hereof were set forth in a separate written contract between the corporation and the director or officer, (ii) is intended to be retroactive and shall be available with respect to events occurring prior to the adoption hereof, and (iii) shall continue to exist after the rescission or restrictive modification hereof with respect to events occurring prior thereto.

Section 5.6. Insurance. The corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the corporation against expenses, liability or loss incurred in respect of the Proceeding, whether or 7 not the corporation would have the power to indemnify such person against such expense, liability or loss under the Michigan Business Corporation Act. Section 5.7. Determinations. Any determination to be made under this Article V by the Board of Directors shall be made as follows: (a) by a majority vote of a quorum consisting of directors of the corporation who were not and are not parties to or threatened with any such action, suit, or proceeding; (b) if the quorum described in paragraph (a) of this Section 5.7 is not obtainable or if a majority vote of a quorum of disinterested directors so directs, in a written opinion by independent legal counsel other than an attorney, or a firm having associated with it an attorney, who has been retained by or who has performed services for the corporation or any person to be indemnified within the past five years; (c) by the shareholders; or (d) by the court of common pleas or the court in which such action, suit, or proceeding was brought.

ARTICLE VII SEAL A corporate seal shall not be required. If the Board of Directors elects to provide a seal, failure to affix such seal to any document shall not affect the validity thereof. ARTICLE VIII AMENDMENT These Bylaws may be altered, amended or repealed, or new Bylaws may be adopted, (i) at any annual or special meeting of the shareholders called for that purpose, by the affirmative vote of the holders of shares entitling them to exercise a majority of the voting power of the corporation on the proposal, or (ii) without a meeting by the written consent of the holders of the corporation's common shares entitling them to exercise two-thirds of the voting power of the corporation on such proposal. 9
