Paragraph 3 shall be deleted in its entirety and the following Article III shall be substituted in its stead:

The personal liability of a director to the Corporation or its shareholders shall be limited to the fullest extent permitted by Section 33-636(b)(4) of the Act. If the Act is hereafter amended or superseded to incorporate provisions further eliminating or limiting the personal liability of a director, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the Act, as so amended or superseded. Neither the amendment nor repeal of this Article, nor the adoption of any provision of the Certificate of Incorporation of the Corporation inconsistent with this Article shall eliminate or reduce the effect of this Article in respect of any matter occurring, or any cause of action, suit or claim that, but for this Article, would accrue or arise, prior to such amendment, repeal or adoption of an inconsistent provision.

Paragraph 4 shall be deleted in its entirety and the following Article IV shall be substituted in its stead: The Corporation shall be permitted to indemnify a director of the Corporation for liability to any person for any action taken, or any failure to take any action, as director of the Corporation to the fullest extent permitted by Section 33-636(b)(5) of the Act. If the Act is hereafter amended or superseded to incorporate provisions providing greater indemnification of a director for liability, then the Corporation shall be permitted to provide such greater indemnification to the fullest extent permitted by the Act as so amended or superseded. Neither the amendment nor repeal of this Article, nor the adoption of the Certificate of Incorporation inconsistent with this Article, shall affect the Corporation’s power to indemnify, or advance expenses to, a director of the Corporation for any liability stemming from acts or omissions occurring prior to such amendment, repeal or adoption of an inconsistent provision. For purposes of this Article, the terms “director” and “liability”, as they relate to a director of the Corporation and liability incurred by such director in his capacity as a director of the Corporation, shall have the respective meanings ascribed to the terms “director” and “liability” in Section 33-770 of the Act, as now in effect or as it may hereafter be amended or superseded.
