15% Special Meeting Right. Article IV, Section 3 has been amended to give stockholders the right to call a special meeting of stockholders upon written request of holders of record who hold a “net long position” (as defined in the Amended Bylaws) of not less than fifteen percent (15%) of the voting power of Apache’s outstanding shares of common stock. Article IV, Section 3, as amended, sets forth the procedures and required disclosure applicable to stockholders requesting a special meeting of stockholders. A stockholder or group of stockholders requesting a special meeting must have held the requisite voting power continuously for at least three years before the date of submitting the written request for the special meeting and are required to include information and representations with the written request concerning the identity of the stockholders requesting such meeting, the purpose or purposes of the special meeting and the matters to be considered at such meeting, the number of shares intended to be counted in determining whether the stockholders making such request hold the requisite voting power. The Amended Bylaws provide that a special meeting request may be disregarded or a stockholder meeting not be held if (i) the stated business is not a proper subject for stockholder action under applicable law or (ii) the same business will be considered at a special or regular meeting of stockholders called by the Board within ninety (90) days after the special meeting request is delivered to or received by Apache.
