The following procedures have been established by the Board in order to facilitate communications between our stockholders and the Board:

​

Stockholders may send correspondence, which should indicate that the sender is a stockholder, to the Board or to any individual director, by mail to Corporate Secretary, BioLargo, Inc., 14921 Chestnut Street, Westminster, California 92683.

​

Our Secretary will be responsible for the first review and logging of this correspondence and will forward the communication to the director or directors to whom it is addressed unless it is a type of correspondence which the Board has identified as correspondence which may be retained in our files and not sent to directors. The Board has authorized the Secretary to retain and not send to directors communications that: (a) are advertising or promotional in nature (offering goods or services), (b) solely relate to complaints by clients with respect to ordinary course of business customer service and satisfaction issues or (c) clearly are unrelated to our business, industry, management or Board or committee matters. These types of communications will be logged and filed but not circulated to directors. Except as set forth in the preceding sentence, the Secretary will not screen communications sent to directors.

​

The log of stockholder correspondence will be available to members of the Board for inspection. At least once each year, the Secretary will provide to the Board a summary of the communications received from stockholders, including the communications not sent to directors in accordance with the procedures set forth above.

​

Our stockholders may also communicate directly with the presiding or “lead” director, or with the non-management directors as a group, by mail addressed to Lead Director, c/o Corporate Secretary, BioLargo, Inc., 14921 Chestnut Street, Westminster, California 92683.

​

The Company’s Audit Committee has established procedures for the receipt, retention and treatment of complaints regarding questionable accounting, internal controls, and financial improprieties or auditing matters. Any of the Company’s employees may confidentially communicate concerns about any of these matters by mail addressed to Audit Committee, c/o Corporate Secretary, BioLargo, Inc., 14921 Chestnut Street, Westminster, California 92683.

​

Upon receipt of a complaint or concern, a determination will be made whether it pertains to accounting, internal controls or auditing matters and, if it does, it will be handled in accordance with the procedures established by the Audit Committee.
