N.C. Gen. Stat. § 55-8-11

Unless the articles of incorporation or bylaws provide otherwise, the board of directors, without regard to personal interest, may fix the compensation of directors for services in any capacity as a director. The compensation established pursuant to this section of directors of a public corporation or of a corporation that so provides in its articles of incorporation is presumed to be fair to the corporation unless proven not to be fair to the corporation by a preponderance of the evidence.
