Sonoma Pharmaceuticals, Inc., a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the “Corporation”) does hereby certify that:

FIRST: That at a meeting of the Board of Directors of the Corporation resolutions were duly adopted setting forth a proposed amendment of the Corporation’s Restated Certificate of Incorporation, as amended, declaring said amendment to be advisable and calling a meeting of the stockholders of the Corporation for consideration thereof. The resolution setting forth the proposed amendment is as follows:

RESOLVED, that Subsection A of Article FOURTH of the Restated Certificate of Incorporation, as amended, of this Corporation be hereby amended by deleting and substituting by the following Subsection A of Article FOURTH:

“A. Authorized Stock. The Corporation is authorized to issue two classes of stock to be designated respectively Preferred Stock (“Preferred Stock”) and Common Stock (“Common Stock”). Effective at 5:00 p.m. Eastern Time on September 13, 2018, the total number of shares of all classes of capital stock the Corporation shall have authority to issue is twenty-four million seven hundred fourteen thousand two hundred eighty-six (24,714,286). The total number of shares of Preferred Stock the Corporation shall have the authority to issue is seven hundred fourteen thousand two hundred eighty six (714,286). The total number of shares of Common Stock the Corporation shall have the authority to issue is twenty-four million (24,000,000). The Preferred Stock and the Common Stock each shall have a par value of one one-hundredth of one cent ($0.0001) per share. The number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the then outstanding shares of Common Stock, without a vote of the holders of Preferred Stock, or of any series thereof, unless a vote of any such holders of Preferred Stock is required pursuant to the provisions established by the Board of Directors of the Corporation (the “Board of Directors”) in the resolution or resolutions providing for the issue of such Preferred Stock, and if such holders of such Preferred Stock are so entitled to vote thereon, then, except as may otherwise be set forth in this Restated Certificate of Incorporation, the only stockholder approval required shall be the affirmative vote of a majority of the combined voting power of the Common Stock and the Preferred Stock so entitled to vote.

Effective at 5:00 p.m. Eastern Time on June 19, 2019, the date of filing with the Secretary of State of the State of Delaware (such time, on such date, the “Effective Time”) of this Certificate of Amendment pursuant to the DGCL, the Corporation shall effect a one for-nine reverse split whereby each nine (9) shares of the Corporation’s Common Stock, $0.0001 par value per share, issued and outstanding immediately prior to the Effective Time (the “Old Common Stock”) shall automatically, without further action on the part of the Corporation or any holder of Old Common Stock, be reclassified, combined, converted and changed into one (1) fully paid and nonassessable share of common stock, $0.0001 par value per share (the “New Common Stock”), subject to the treatment of fractional share interests as described below. The conversion of the Old Common Stock into New Common Stock will be deemed to occur at the Effective Time. From and after the Effective Time, certificates representing the Old Common Stock shall represent the number of shares of New Common Stock into which such Old Common Stock shall have been converted pursuant to this Certificate of Amendment. In connection with the reverse split, no fractional shares shall be issued. In lieu of fractional shares, the Corporation will pay cash in the amount of the value of the fractional share.

SECOND: That thereafter, pursuant to resolution of the Corporation’s Board of Directors, a special meeting of the stockholders of the Corporation was duly called and held upon notice in accordance with Section 222 of the General Corporation Law of the State of Delaware at which meeting the necessary number of shares as required by statute were voted in favor of the amendment.

THIRD: That said amendment was duly adopted in accordance with the provisions of Section 242 of the General Corporation Law of the State of Delaware.

In WITNESS WHEREOF, Sonoma Pharmaceuticals, Inc. has caused this Certificate to be signed by its duly authorized officer this day of June 18, 2019.
