Exhibit 3.1

CERTIFICATE OF AMENDMENT

OF

RESTATED ARTICLES OF INCORPORATION

OF

QUALSTAR CORPORATION

The undersigned hereby certify that:

“Section 1. On the close of business on the date this Certificate of Amendment is filed with the California Secretary of State (the “Effective Time”), each six (6) shares of Common Stock issued and outstanding or held by the Corporation in treasury stock immediately prior to the Effective Time shall, automatically and without any action on the part of the respective holders thereof or the Corporation, be combined and converted into one (1) share of validly issued, fully paid and non-assessable Common Stock, subject to the treatment of fractional share interests as described below (the “Reverse Stock Split”). No fractional shares of Common Stock shall be issued in connection with the Reverse Stock Split. Rather, any shareholder that would be entitled to receive fractional shares as a result of the Reverse Stock Split shall instead receive a cash payment in lieu thereof equal to the fraction to which such shareholder would otherwise be entitled multiplied by the last sale price of the Common Stock as reported on The Nasdaq Capital Market (as adjusted to reflect the Reverse Stock Split) on the last trading day preceding the effective date of the Reverse Stock Split.

Section 2. The Corporation is authorized to issue two classes of shares designated, respectively, “Common Stock” and “Preferred Stock,” and referred to herein either as Common Stock or Common shares and Preferred Stock or Preferred shares, respectively. The number of shares of Common Stock which the Corporation is authorized to issue is Fifty Million (50,000,000) and the number of shares of Preferred Stock which the Corporation is authorized to issue is Five Million (5,000,000).

Section 3. The Preferred shares may be issued from time to time in one or more series. The Board of Directors is authorized to fix the number of shares of any series of Preferred shares and to determine the designation of any such series. The Board of Directors is also authorized to determine or alter the rights, preferences, privileges, and restrictions granted to or imposed upon any wholly unissued series of Preferred shares and, within the limits and restrictions stated in any resolution or resolutions of the Board of Directors originally fixing the number of shares constituting any series, to increase or decrease (but not below the number of shares of such series then outstanding) the number of shares of any such series subsequent to the issue of shares of that series.”

We further declare under penalty of perjury under the laws of the State of California that the matters set forth in this certificate are true and correct of our own knowledge.
