Article FOURTH of the Amended and Restated Articles of Incorporation is hereby amended by inserting the following language as the beginning of the Article:

“Upon the effectiveness of this Certificate of Amendment provided in Section 4 below (the “Effective Time”), each 4 shares of Common Stock, issued and outstanding immediately prior to the Effective Time, will automatically and without any further action on the part of the Corporation or the holder thereof, be combined into one (1) validly issued, fully paid and non-assessable share of Common Stock (the “Reverse Stock Split”), subject to the treatment of fractional share interests as described below.
