PROXY STATEMENT
FOR
ANNUAL MEETING OF STOCKHOLDERS OF CYANOTECH CORPORATION
To Be Held Monday, August 29, 2011

This Proxy Statement is furnished in connection with the solicitation by the Board of Directors of CYANOTECH CORPORATION (the “Company” or “Cyanotech”) of proxies to be voted at the 2011 Annual Meeting of Stockholders (the “Annual Meeting”) which will be held on Monday, August 29, 2011 at 3:00 P.M., Hawaii Standard Time, at the Waikoloa Beach Marriott, 69-275 Waikoloa Beach Drive, Waikoloa, Hawaii, USA, 96738, or at any adjournment or postponement thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Stockholders. On July 20, 2011, the Company distributed to stockholders of record a Meeting Notice Regarding the Availability of Proxy Materials for this meeting containing instructions on how to access via the internet (www.envisionreports.com/CYAN) this Proxy Statement, the Notice of Annual Meeting, the form of proxy and our Annual Report on Form 10-K for the fiscal year ended March 31, 2011, and our undertaking to also mail a full set of such proxy materials, together with a postage paid envelope for returning non-electronic proxy cards, to any stockholders who request paper copies at no cost to them.

The Company’s principal executive offices are located at 73-4460 Queen Kaahumanu Highway, Suite 102, Kailua-Kona, HI 96740.

VOTING RIGHTS AND SOLICITATION

The enclosed proxy is being solicited on behalf of the Board of Directors of Cyanotech for use at the Annual Meeting, so that your shares will count toward determination of the presence of a quorum and your shares can be voted at the meeting.

Who May Vote:  The close of business on July 8, 2011 is the record date for stockholders entitled to notice of and to vote at the Annual Meeting. All holders of the Company’s Common Stock outstanding on the record date are entitled to vote at the Annual Meeting. Each stockholder has one vote for each share so held. At July 8, 2011, 5,395,168 shares of Common Stock, $.02 par value per share, were issued and outstanding.  You may vote by submitting your proxy card by internet, telephone, mail or in person at the meeting, or you may attend the meeting and vote your shares in person by ballot.

Methods of Voting:  All stockholders of record may vote by mail by completing, signing, dating and returning their proxy cards in the postage-paid envelope.  If you sign, date and return your proxy card without indicating how you want to vote, your proxy will be voted as recommended by the Board of Directors.  Stockholders of record can instead vote by toll-free telephone or the internet website address listed on the proxy card; they may also vote by proxy card or by ballot if personally present at the meeting, but only the last vote before the polls close at the meeting will count.  Stockholders who hold their shares through a broker, trustee or other nominee also can vote by telephone or internet as instructed by their bank, broker or other nominee; as “beneficial owners” they can also vote at the meeting if they present a separate “legal proxy” from the actual record holder and in that event only the final vote made in the name of the stockholder of record will count.

The presence in person or by proxy of the holders of record of a majority of the voting power of the outstanding shares entitled to vote constitutes a quorum. Directors are elected by a plurality of votes cast. For approval of all other matters to be voted on, when a quorum is present a matter is approved if the number of votes cast in favor of the action taken exceeds the number of votes cast in opposition to the action, except that Proposal THREE requires that a majority of all outstanding shares be voted for approval.. Abstentions are counted only for purposes of determining whether a quorum is present.

Voting Shares Held by Brokers, Banks and Other Nominees:  Votes will be counted by the inspector of election appointed for the meeting, who will separately count “For” and “Withhold” and, with respect to any proposals other than the election of directors, “Against” votes, abstentions and broker non-votes.  A “broker non-vote” occurs when a broker, trustee or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker, trustee or other nominee does not have discretionary voting power with respect to that proposal and has not received instructions with respect to that proposal from the beneficial owner, despite voting on at least one other proposal for which it does have discretionary authority or for which it has received instructions.

Many of our stockholders may hold some or all of their shares through a broker, trustee or other nominee, rather than directly in their own name.  As summarized below, there are distinctions between shares held of record and those owned beneficially.

Table of Contents

·                  Stockholders of Record — If your shares are registered directly in your name with our transfer agent, you are considered, with respect to those shares, the “stockholder of record.”  As the stockholder of record, you have the right to grant your voting proxy directly to us or to a third party and to vote by completing a proxy card by internet, by telephone or by mail, or to vote in person by ballot or by proxy at the Annual Meeting of Stockholders.

·               Beneficial Owners — If any or all of your shares are held in a brokerage account, by trustee or by another nominee, you are considered, with respect to those shares, the “beneficial owner.”  As the beneficial owner of those shares, you have the right by internet, telephone or mail to direct your broker, trustee or nominee how to vote, and you also are invited to attend the Annual Meeting of Stockholders in person.  Because a beneficial owner is not the stockholder of record, however, you may not vote these shares in person at the Annual Meeting of Stockholders unless you obtain a “legal proxy” from the broker, trustee or other nominee that holds your shares, giving you the right to vote the shares at the Annual Meeting of Stockholders.

For your vote to be counted, you must communicate your voting decisions by internet, telephone or mail to your broker, trustee or other nominee before the date of the stockholders meeting.  Brokers, trustees and other nominees who do not receive instructions are entitled to vote those shares with respect to the two proposals to amend existing stock plans and the ratification of the selection of our independent registered public accounting firm, but not with respect to election of directors.  Abstentions and broker non-votes will be included only in determining the presence of a quorum at the Annual Meeting, but will not be counted as votes cast on any proposals to be voted upon.

Voting your shares is important to ensure that you have a say in the governance of your Company.  Please review these proxy materials and if you are a beneficial owner follow the voting instruction form you receive from your broker, bank or other nominee to vote your shares.  We hope that you will exercise your rights and fully participate as a stockholder in our Company’s future.  If you have any questions about this new rule or the proxy process in general, please contact the broker, bank or other financial institution where you hold your shares.  The SEC also has a website (www.sec.gov/spotlight/proxymatters.shtml) with more information about your rights as a stockholder.  Additionally, you may contact Deanna Spooner, Corporate Secretary, by telephone at 808-326-1353 or by email to dspooner@cyanotech.com.

Voting Shares by Proxy:  Shares represented by proxies in the accompanying form which are properly executed and returned to Cyanotech by internet, by mail or by telephone will be voted at the Annual Meeting in accordance with the stockholder’s instructions contained on the proxy or herein. To submit your proxy by mail, mark your votes on the enclosed form of proxy, then follow the directions on the form of proxy. To submit your proxy using the internet or by telephone, see the instructions on the proxy form and have the proxy form available when you access the internet website or place your telephone call. In the absence of contrary voting instructions properly submitted, all shares represented by properly submitted proxies which have not been revoked will be voted:

a)             FOR the election of each of the directors as described herein under “Proposal ONE—Election of Directors”;

b)            FOR Proposal TWO to amend the 2005 Stock Option Plan (“2005 Plan”) to increase by 1,375,000 shares to a total of 2,075,000 shares the amount of the company’s common stock authorized for option grant and subsequent issuance under the 2005 Plan;

c)             FOR Proposal THREE to amend the 2004 Independent Director Stock Option and Restricted Stock Grant Plan (“2004 Plan”) to increase by 125,000 shares to a total of 200,000 shares the amount of the Company’s common stock authorized for option grant, restricted stock grant and issuance under the 2004 Plan; and

d)            FOR Proposal FOUR to Ratify the Selection of Grant Thornton LLP as the Company’s Independent Registered Public Accounting Firm for Fiscal Year 2012.

Management does not know of any other matters to be presented at this Annual Meeting other than those set forth in this Proxy Statement and in the Notice accompanying this Proxy Statement. If other matters should properly come before the meeting, the proxy holders will vote on such matters in accordance with their best judgment.

The entire cost of soliciting the proxies will be borne by Cyanotech. Proxies will be solicited principally through the use of the mails, but, if deemed desirable, may be solicited personally or by telephone, e-mail, facsimile or letters from officers and regular Cyanotech employees who will receive no additional compensation. Arrangements may be made with brokerage houses and other custodians, nominees and fiduciaries to send proxies and proxy material to the beneficial owners of the Company’s Common Stock, and such persons may be reimbursed for their expenses.

Revoking Your Proxy:  Any person giving a proxy pursuant to this solicitation has the power to revoke it at any time before it is exercised at the stockholder meeting. It may be revoked by filing with the Secretary of the Company at the Company’s principal executive office, 73-4460 Queen Kaahumanu Highway, Suite 102, Kailua-Kona, HI 96740, a written notice of revocation or a duly executed proxy bearing a later date, or it may be revoked by attending the meeting, notifying the Secretary of the Meeting of the revocation of the prior proxy, and voting in person. Attendance at the meeting will not, by itself, revoke a proxy.

IMPORTANT NOTICE

Regarding Availability of Proxy Materials

·               Stockholders of Record.  If your shares are registered in your own name, you may enroll to have future proxy materials delivered via e-mail or the internet by following the instructions at www.envisionreports.com/CYAN.  You will need the control number on your proxy card to enroll.

Delivery of One Proxy Statement and Annual Report

To a Single Household to Reduce Duplicate Mailings

Each year in connection with the Annual Meeting of Stockholders, the Company is required to furnish to each stockholder of record a proxy statement and annual report and to arrange for a proxy statement, annual report and, if applicable, notice of internet availability of proxy materials to be furnished to each beneficial stockholder whose shares are held by or in the name of a broker, bank, trust or other nominee.  Because many stockholders hold shares of the Cyanotech Common Stock in multiple accounts, this process may result in duplicate mailings of proxy materials to stockholders who share the same address.  Stockholders can avoid receiving duplicate mailings and save the Company the cost of producing and mailing duplicate documents as follows:

·               Stockholders of Record.  If your shares are registered in your own name and you are interested in consenting to the delivery of a single copy of proxy materials (other than proxy cards), you may also do so via the internet by going directly to www.envisionreports.com/CYAN and following the instructions therein.

·               Beneficial Stockholders.  If your shares are not registered in your own name, your broker, bank, trust or other nominee that holds your shares may have asked you to consent to the delivery of a single copy of proxy materials (other than proxy cards) if there are other stockholders who share an address with you.  If you currently receive more than one copy of proxy materials at your household and would like to receive only one copy in the future, you should contact your nominee.

Right to Request Separate Copies.  If you consent to the delivery of a single copy of proxy materials but later decide that you would prefer to receive a separate copy of proxy material for each account at your address, then please notify the Company or your nominee, as applicable, and the Company or your nominee will promptly deliver such additional proxy materials.  If you wish to receive a separate copy of the proxy materials for each account at your address in the future, please call toll-free 1-866-641-4276 or send an email to investorvote@computershare.com.

PROPOSAL ONE

Election of Directors

Board Nominees

A board of seven directors is to be elected at the meeting. Unless otherwise instructed, the proxy holders will vote the proxies received by them FOR the election of the seven Board nominees named below, all seven of whom are presently directors of the Company. Each nominee has consented to be named a nominee in this Proxy Statement and to continue to serve as a director if elected. If any nominee becomes unable or declines to serve as a director or if additional persons are nominated at the meeting, the proxy holders intend to vote all proxies received by them in such a manner as will assure the election of as many nominees listed below as possible (or, if new nominees have been designated by the Board of Directors, in such a manner as to elect such nominees) and the specific nominees to be voted for will be determined by the proxy holders. The Company is not aware of any reason that any nominee will be unable or will decline to serve as a director. Each director elected at this Annual Meeting will serve until the next Annual Meeting or until such director’s successor has been elected and qualified. Voting for the election of directors is non-cumulative. It is the Company’s policy that all Board members attend each annual meeting of stockholders; last year five of six Board members attended the annual meeting of stockholders.

The following sets forth certain information on each of the nominees for election to serve as a director of the Company until the 2012 Annual Meeting of Stockholders including each director’s background, principal occupations and employment, as well as, specific experience, qualifications, attributes and skills that led to the Board’s conclusion that each of the nominees for director should serve on the Board at the time of this Proxy Statement, in light of the Company’s current business and structure:

BOARD MEETINGS AND COMMITTEES

Board Meetings

During fiscal year 2011 the Board met seven (7) times. Each of our Directors attended 75 percent or more of the meetings of the Board and of Board Committees on which he served.

Director Nomination Process

Director Qualifications.   The Nominating and Corporate Governance Committee has established guidelines for considering nominations to the Company’s Board of Directors. These include: (a) personal characteristics, including such matters as integrity, education, diversity of background and experience, absence of potential conflicts of interest with the Company or its operations, and the availability and willingness to devote sufficient time to the duties of a director of the Company; (b) experience in corporate management, such as serving as an officer or former officer of a publicly held company; (c) experience in the Company’s industry and with relevant social policy concerns; (d) experience as a board member of another company; (e) academic expertise in an area of the Company’s operations; and (f) practical and mature business judgment. The criteria are not exhaustive and the Nominating and Corporate Governance Committee and the Board of Directors may consider other qualifications and attributes which the members believe are appropriate in evaluating the ability of an individual to serve as a member of the Board of Directors. Other considerations are set forth in the Company’s Bylaws.  The Nominating and Corporate Governance Committee’s goal is to assemble a Board of Directors that brings to the Company a variety of perspectives and skills derived from high quality business and professional experience. In doing so the Committee also considers candidates with appropriate non-business backgrounds.

Identification and Evaluation of Nominees for Directors.   The Board of Directors believes that, based on the Nominating and Corporate Governance Committee’s knowledge of the Company’s corporate governance principles and the needs and qualifications of the Board at any given time, the Nominating and Corporate Governance Committee is best equipped to select nominees that will result in a well-qualified and well-rounded board of directors. It is the general policy of the Nominating and Corporate Governance Committee not to accept unsolicited nominations from stockholders.  The Company’s Bylaws contain procedures for stockholder nominations which are discussed in greater detail under “STOCKHOLDER PROPOSALS AND NOMINATIONS” on page 22 hereof. In making its nominations, the Nominating and Corporate Governance Committee identifies nominees by first evaluating the current members of the Board willing to continue their service. Current members with qualifications and skills that are consistent with the committee’s criteria for Board service are re-nominated. As to new candidates, the committee will generally poll the Board members and members of management for recommendations and, if appropriate, engage a consultant to assist the Committee. The committee may also review the composition and qualification of the boards of directors of the Company’s competitors, and may seek input from industry experts or analysts. The committee reviews the qualifications, experience and background of the candidates. Final candidates are interviewed by the independent directors and executive management. In making its determinations, the committee evaluates each individual in the context of the Board as whole, with the objective of assembling a group that can best represent stockholder interests through the exercise of sound judgment. After review of all pertinent data, and due deliberation by the committee, this slate of nominees is recommended to the Board of Directors and the stockholders for election.

Each of the nominees for election at this annual meeting was unanimously recommended by the Nominating and Corporate Governance Committee for election.

Independent Directors

The Board has determined that each of the nominees for director, other than Mr. Bailey and Dr. Cysewski, has no material relationship with the Company (either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company) and is “independent” under Nasdaq Rule 5605(a)(2). In making its determination, the Board considered transactions and relationships between each director (and any member of his immediate family) and the Company and its subsidiaries and relationships between the directors or their affiliates and members of the Company’s senior management personnel and their affiliates.

Under Nasdaq Rule 5605(a)(2), an “Independent Director” is a person other than an Executive Officer of the company having a relationship which, in the opinion of the company’s board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.  Since Mr. Bailey is President and Chief Executive Officer of the Company, and since Dr. Cysewski is Executive Vice President and Chief Scientific Officer of the Company, neither may be considered an “Independent Director” under Nasdaq Rule 5605(a)(2).  Upon Mr. Rosenthal’s completion of his temporary appointment as Interim President and Chief Executive Officer on January 11, 2011, his status was re-evaluated under Nasdaq rules applicable to directors who accept such temporary executive appointments and he was determined by the Board of Directors to once again be independent under that Nasdaq Rule.

Table of Contents

The Independent Directors meet in executive session without the Chief Executive Officer or any other member of management in attendance at least twice annually in accordance with Nasdaq Corporate Governance Rules. In fiscal year 2011 there were five (5) such sessions. Gregg W. Robertson served as Chairman of such meetings until October 26, 2011 and Michael A. Davis served as Chairman of such meetings since October 26, 2010.  The Chairman, in conjunction with each other independent director, raised the issues discussed. Any Independent Director may request an executive session of Independent Directors to discuss any matter of concern.

Stockholders may, at any time, communicate in writing with any particular director, or the non-management directors as a group, by sending such written communication to Cyanotech Corporation—Non-Management Directors (or to a specific named-director), 73-4460 Queen Kaahumanu Highway, #102, Kailua-Kona, Hawaii, 96740, or by e-mail to board@cyanotech.com. All written communications received will be directed to the relevant director or the non-management directors as a group.

Code of Conduct and Ethics

The Company has established a Code of Conduct and Ethics that applies to each of the Company’s officers, directors and employees. The Code of Conduct and Ethics is posted on the Company’s web-site www.cyanotech.com. The Code of Conduct and Ethics contains general guidelines for conducting the business of the Company consistent with the highest standards of business ethics, and is intended to qualify as a “code of ethics” within the meaning of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules promulgated thereunder and as a “code of conduct” within the meaning of the Nasdaq listing standards.

Corporate Governance

In addition to the Company’s Amended and Restated Articles of Incorporation, the Company’s Amended and Restated Bylaws and other key Company governance documents, including its Audit Committee Charter, Compensation and Stock Option Committee Charter, Nominating and Governance Committee Charter and the Code of Conduct and Ethics, are available on the Company’s website at www.cyanotech.com. The information contained on the website is not hereby incorporated by reference in, or considered part of, this Proxy Statement, unless specifically incorporated. The Company will provide copies of any of these documents, free of charge, to any stockholder upon written request to the Chief Financial Officer, c/o Cyanotech Corporation, 73-4460 Queen Kaahumanu Highway, #102, Kailua-Kona, Hawaii, 96740.

The Company has chosen to separate the chief executive officer and board chairman positions as a matter of good corporate governance and to efficiently utilize the skills and time of the individuals who currently serve in these positions. Mr. Bailey, the Company’s President and Chief Executive Officer is primarily involved in the day to day responsibilities and obligations of the Company, while Mr. Davis, the Board’s Chairman, provides strategic direction for the Company and presides over meetings of the Board.  These two key leaders communicate regularly with each other.

The Board of seven is limited by its size, but plays a fundamental role in the Company’s risk oversight process, both directly and through the delegation to its committees of responsibilities related to the oversight of certain risks, and regularly discusses with management the Company’s major risk exposures, their potential impact on the Company’s business and the steps the Company can take to manage them.

While the Board is ultimately responsible for all risk oversight of the Company, the Audit Committee focuses on financial risks as they relate to the Company’s financial reporting process, financial statements and internal controls, among other responsibilities set forth in the Audit Committee’s Charter.  The Nominating and Corporate Governance Committee focuses on the management of risks associated with the Board’s organization, membership, governance and structure. The Compensation and Stock Option Committee assists the Board in fulfilling its oversight responsibilities with respect to the management of risks arising from the Company’s compensation policies, bonus plans and incentive option plans.  Finally, the Finance Committee oversees financial policies of the Company and makes recommendations to the Board in matters including capital structure, equity and debt financings, capital expenditures and cash management.

The Company has an ongoing commitment to good governance and business practices.  This includes regular monitoring and balancing of the Company’s processes and procedures in light of any new corporate governance best practices, and a continual review of changes in federal law and the rules and regulations promulgated by the SEC and the regulations of the Nasdaq Stock Market, LLC.  These practices help to ensure that the Company will timely comply with new laws and rules and will implement other corporate governance practices which it believes to be in the best interest of the Company and its stockholders.

Board Committees

The Board of Directors of the Company has an Audit Committee, Nominating and Governance Committee, Compensation and Stock Option Committee and a Finance Committee.

The Audit Committee operates and acts under a written charter, which was revised and approved by the Cyanotech Board of Directors on January 7, 2010. A copy of the Charter and Powers of the Audit Committee can be found on the Company’s website at www.cyanotech.com. The Committee provides independent and objective oversight of (1) the Company’s financial reporting processes, (2) the Company’s audits of the financial statements, including appointment, compensation and oversight of the Company’s independent registered public accounting firm, (3) the Company’s internal controls, and (4) risk assessment and risk management policies set by management. The Committee also oversees and monitors the independence, performance and qualifications of the Company’s independent registered public accounting firm. The Audit Committee also reviews and approves related party transactions and reviews and resolves complaints from any employee regarding accounting, internal controls or auditing matters. All members of the Audit Committee are “independent” directors as defined in Nasdaq Rules 5605(a)(2) and 5605-3(2)(A). On October 26, 2010, Gregg W. Robertson, chair of the Committee, resigned from the Board and the Company no longer complied with Nasdaq’s audit committee requirements as set forth in Listing Rule 5605. On January 26, 2011, the Board of Directors elected Ralph K. Carlton to the Board and determined that he met the requirements as a “financial expert” as defined in Rule 10A(m) of the Act. Mr. Carlton was named to serve on the Audit Committee and was selected as its Chair. Through that action, the Company regained compliance with Nasdaq requirements. The Committee held four (4) meetings during fiscal year 2011and is now comprised of independent directors Ralph K Carlton (Chair), Michael A. Davis and John T. Waldron.

The Nominating and Corporate Governance Committee operates and acts under a written charter, which was adopted and approved by the Cyanotech Board of Directors on January 7, 2010, a copy of which can be found on the company’s website at www.cyanotech.com. The Nominating and Corporate Governance Committee’s functions include (1) reviewing the background and qualifications of potential nominees for the Cyanotech Board of Directors presented by stockholders, directors and management, (2) recommending to the Board a slate of nominees to be submitted to the stockholders for election at the next Annual Meeting of Stockholders, (3) advising the Board with respect to matters of Board composition and procedures, and (4) overseeing the annual evaluation of the Board. Among the qualifications considered in the selection of candidates are knowledge, experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability, dedication and absence of conflicts of interest see caption “Director Nomination Process” above. All members of the Nominating and Corporate Governance Committee are “independent” directors under Nasdaq Rule 5605(a)(2). The Nominating and Corporate Governance Committee, comprised of independent directors Michael A. Davis (Chair), Ralph K. Carlton and John T. Waldron, held three (3) regularly scheduled meeting during fiscal year 2011.

The Compensation and Stock Option Committee operates and acts under a written charter, which was adopted and approved by the Cyanotech Board of Directors on January 7, 2010 and which is also available on the Company’s website at www.cyanotech.com. The Compensation and Stock Option Committee reviews and makes recommendations to the Board concerning the Company’s executive compensation policy, bonus plans and incentive option plans, and approves the grants of stock options to officers, employees and consultants. Based on such review, the Committee recommended to the Board that such information be included in the Company’s proxy statement. At least once a year, the Compensation and Stock Option Committee meets in executive session with the other independent directors of the Board to evaluate the Chief Executive Officer’s (“CEO”) performance. All members of the Compensation and Stock Option Committee are “independent” directors as defined under Nasdaq Rule 5605(a)(2). The Compensation and Stock Option Committee, comprised of independent directors John T. Waldron (Chair), David I. Rosenthal and John T. Waldron, held five (5) regularly scheduled meetings during fiscal year 2010.

The Finance Committee, composed of three independent directors, also operates under a written charter approved by the Cyanotech Board of Directors.  The committee is charged with overseeing financial policies of the Company and making recommendations to the Board for its consideration and action, pertaining to matters such as:  capital structure; equity and debt financings; capital expenditures; cash management; banking activities and relationships; investments; foreign exchange activities; share repurchase activities; and any other activity which may be considered high risk or which could have a material effect on the Company’s financial position or results of operations, and subject to receiving specific assignments from the Board.

DIRECTOR COMPENSATION

The following table sets forth the compensation earned by non-employee directors for fiscal year 2011:

At the 2004 Annual Meeting of Stockholders, the stockholders of the Company approved the 2004 Independent Director Stock Option and Stock Grant Plan (the “2004 Plan”). Under the 2004 Plan each independent director receives on first election, pursuant to the 2004 Plan, a 10-year option to purchase 1,000 shares of the Company’s Common Stock, and thereafter a grant of 875 shares of Common Stock each year that the Independent director is elected to the Board. Such grants and options are non-transferable and non-exercisable for six months following the date of grant.  Under the 2004 Plan 75,000 shares (adjusted for a 2006 reverse stock split) were reserved for issuance or option grant through the date of the 2014 Annual Stockholders’ Meeting.  On March 24, 2010, the Independent directors approved a revision to the 2004 Plan to provide for the grant of 2,000 shares of Common Stock each year that an independent director is elected to the Board and 4,000 for the director serving as Chairman of the Board.  The modification was effective for one-half of the current year.

In addition, each independent director receives an annual fee of $6,000 for participation on the Board ($10,000 - Chairman) and $2,500 per Board meeting attended in person ($4,000 - Chairman), and is also reimbursed for out-of-pocket costs incurred in connection with attendance at such meetings. Each independent director receives $500 for participation in telephonic meetings ($1,000 - Chairman). An independent director who serves as a member of any Board committee receives an annual fee of $1,500 and an Independent Director who serves as chairperson of a Board committee is entitled to additional compensation as follows:  1) Audit Committee Chairperson—$4,000; 2) Compensation and Stock Option Committee Chairperson—$2,500; 3) Nominating and Corporate Governance Committee—$2,500; and 4) Finance Committee Chairperson—$4,000.

PROPOSAL TWO:

Amend the 2005 Stock Option Plan to Increase by 1,375,000 Shares to a Total of 2,075,000 Shares the Amount of the Company’s Common Stock Authorized for Option Grant and Subsequent Issuance under the 2005 Stock Option Plan

The 2005 Stock Option Plan (“2005 Plan”) was adopted at the 2005 Annual Stockholder’s Meeting on August 22, 2005 with the objective of promoting the interests of the Company by providing officers and key employees with the opportunity to acquire common stock of the company as an incentive to accept a position with the Company or to remain in the service of the Company. Non-employee board members are not eligible to participate in the 2005 Plan.

The 2005 Plan originally provided for 800,0000 shares of common stock, par value $0.05, to be reserved for issuance; however, that number was automatically reduced to 200,0000 shares of common stock, par value $0.02, in 2006 as a result of a reverse stock split affecting all authorized shares of the Company. The 2005 Plan is administered by the Compensation and Stock Option Committee (“Committee”), subject to approval of the Committee’s recommendations by the Board of Directors (“Board”); provided, however, any recommendation for a material increase in the maximum number of shares issuable under the 2005 Plan, a material modification in the eligibility requirements for Plan participation or a material increase in benefits accruing to optionees, is subject to approval by the stockholders of the Company. Proposal TWO requires stockholder approval.

Table of Contents

On May 16, 2008, the Company appointed a new President and Chief Executive Officer under a Letter Agreement of employment which required the grant of options equal to 7.5% of the then-issued and outstanding shares of common stock of the Company.  In order to accommodate the option commitments, on September 9, 2008, stockholders approved an increase in total the authorized shares available for stock option grants under the 2005 Plan to be increased by 500,000 to 700,000 shares. The entire 2005 Plan as Restated was filed as Exhibit 10.2 to the Company’s period report of SEC Form 10-Q filed on November 10, 2010.

On November 5, 2010, the Company appointed Brent D. Bailey to the position of President and Chief Executive Officer under a Letter Agreement of Employment (“Agreement”) effective January 11, 2011. At November 5, 2010, there were only approximately 400,000 shares available for stock option grants under the 2005 Plan. The Agreement, which covers seven years of Mr. Bailey’s employment as President and Chief Executive Officer, provides for the grant of options under the 2005 Plan equal to 13.5% of the then-issued and outstanding shares of common stock of the Company or a total of 727,916 shares. Mr. Bailey’s options vest annually over seven years. (See also, “How was the Chief Executive Officer’s compensation determined last fiscal year?” on page 20.) Pursuant to the Agreement he received an immediate grant of 230,000 options, upon the actual commencement of his employment, with the balance to remain subject to stockholder approval of an increase in shares authorized for issuance under the 2005 Plan at the 2011 Annual Stockholders Meeting. In order to accommodate the option commitment to Mr. Bailey and to provide additional shares for possible incentive grants to other eligible executives and employees, the Committee recommended to the Board that it recommend to all stockholders that total authorized shares available for stock option grants be increased by 1,375,000 shares to 2,075,000 shares. Mr. Bailey is directly interested in the outcome of Proposal TWO. If Proposal TWO is adopted the 1,375,000 share increase will cover the remaining 497,916 options promised to Mr. Bailey, 33,000 to other eligible employees and provide up to 854,288 shares for possible incentive grants under the 2005 Plan before it expires on August 21, 2015.

2005 Plan Benefits as Proposed to be Amended

(1)   Mr. Bailey was granted 230,000 options to purchase shares of the Company’s common stock on January 12, 2011 and promised 497,916 options to be granted upon stockholder approval of Proposal TWO.  These options vest as to 81,000 on January 11, 2012; 81,000 on January 11, 2013; 108,000 on January 11, 2014; 108,000 on January 11, 2015; 108,000 on January 11, 2016; 108,000 on January 11, 2017; and 133,916 on January 11, 2018.

(2)   All options under the 2005 Plan are granted at the Fair Market Value (closing price) of the Company’s common stock on the date of grant and are exercisable for an equivalent number of shares of the Company’s common stock.  The closing price of Company’s common stock on July 8, 2011, the latest practicable date, was $3.55 per share.

Table of Contents

Total eligible employees now number approximately 70; to date no consultants or independent contractors have been granted options under the Plan. Shares issuable under the 2005 Plan will either be shares of the Company’s authorized but previously unissued common stock, or shares reacquired by the Company, including shares purchased on the open market. All shares granted in the form of options under the 2005 Plan will reduce, on a share for share basis, the number of shares available for subsequent grants. Option grants which were forfeited under the terms of the 2005 Plan will return to the pool of reserved shares and be available for subsequent grants.

Other material features of the 2005 Plan include:  (a) each option granted is exercisable at such time or times up to ten years from date of grant, and for such number of shares as is determined by the Committee and set forth in a duly executed stock option agreement; (b) provision is made for termination or transfer of options in the event of an optionee’s termination for misconduct, voluntary termination, cessation of service prior to date of exercise, or death, with discretion in the Committee to determine any post-event adjustments in the exercise dates; (c) option exercise dates may become accelerated upon the occurrence of certain major corporate transactions or a change in control of the Company; (d) the granting of any option, including options available because of the adoption of Proposal TWO, is subject to prior approval, if any is necessary, by regulatory authorities; and (e) no shares of the Company’s common stock may be issued under the 2005 Plan until full compliance with all applicable federal and state securities laws, including registration of all additional shares proposed in Proposal TWO.

Under the 2005 Plan employees and certain independent consultants may be granted options to purchase shares of the Company’s common stock. Options granted pursuant to the 2005 Plan will be options intended to qualify as incentive stock options under Section 422 of the Internal Revenue Code if granted to employees, or non-statutory stock options which may be granted to both employees and certain independent consultants, as determined by the Committee. Incentive stock options must be granted for no less than 100% of the market value of the shares as determined on the date of grant, while non-statutory stock options may be granted at any price set by the Committee subject to certain restrictions under the Code. The 2005 Plan also provides that the maximum aggregate fair market value of stock initially exercisable by any person under incentive stock options may not exceed $100,000. Any individual exercise of options in an amount above $100,000 in one calendar year can only be exercised as non-qualified options.

Because of the Company’s previously disclosed federal and state net operating loss carryforward positions, an increase in authorized and granted options will result in no income tax consequences to the Company under existing tax law and regulations for either issuance or exercise. However, with respect to recipients of incentive stock option grants, while there are no immediate tax liabilities upon issuance of any options, tax liabilities will apply on the sale of the underlying stock. With respect to recipients of non-qualified stock option grants, tax liabilities may apply upon issuance or exercise, and will apply upon sale.

FISCAL YEAR-END OPTION VALUES

The following table provides information with respect to the named executive officers concerning the number and value of unexercised options held at year end. No SARs have been granted under the Company’s 2005 Stock Plan.

PROPOSAL THREE:

Amend the 2004 Independent Director Stock Option and Restricted Stock Plan to Increase by 125,000 Shares to a Total of 200,000 Shares the Amount of the Company’s Common Stock Authorized for Issuance under the 2004 Independent Director Stock Option and Restricted Stock Plan

The 2004 Independent Director Stock Option and Restricted Stock Plan (“2004 Plan”) was adopted at the 2004 Annual Stockholder’s Meeting on August 16, 2004 with the objective of attracting and retaining qualified non-employee persons to serve on the Board of Directors of the Company and to enhance the future growth of the Company by aligning the independent directors interest with the interest of the Company and its stockholders. The 2004 Plan originally provided for 300,0000 shares of common stock, par value $0.05, to be reserved for issuance; however, that number was automatically reduced to 75,000 shares of common stock, par value $0.02, in 2006 as a result of a reverse stock split affecting all authorized shares of the Company.  The 2004 Plan is administered by the Chief Executive Officer and Chief Financial Officer of the Company according to its terms. The Board of Directors may modify, revise or terminate the 2004 Plan at any time and from time to time; provided, however, that the 2004 Plan shall not be amended more than once every six (6) months, other than to comport with changes in the Code, or the regulations thereunder, or the Employee Retirement Income Security Act of 1974, as amended, or the regulations thereunder; and provided, further, that without the approval of the holders of at least a majority of the outstanding Shares of the Company’s voting stock, the Board of Directors may not (i) materially increase the benefits accruing to Participants under the 2004 Plan; (ii) change the aggregate number of Shares which may be issued under the 2004 Plan; (iii) reduce the Option price at which Options have been granted; or (iv) change the class of persons eligible to receive Options. No termination or amendment of the 2004 Plan may, without the consent of the holder of any Option then outstanding adversely affect the rights of such holder under the Option.

Options will be granted to persons who are newly elected independent directors of the Company. On the Effective Date, each newly elected independent director received without the exercise of the discretion of any person or persons, 10-year Options exercisable for 1,000 shares (adjusted for 2006 reverse stock split). Thereafter, as of the date of the annual meeting of stockholders in each year after 2004 that the 2004 Plan was in effect, each independent director then elected or continuing in office who did not previously receive a grant of Options hereunder was granted or shall receive, without the exercise of the discretion of any person or persons, 10-year Options exercisable for 1,000 Shares. If, as of any annual meeting date, there are not sufficient Shares available under the 2004 Plan to allow for the grant to each eligible independent director of Options for Shares pursuant to Section III (d) for the number of Shares provided herein, each eligible independent director shall receive Options or Shares for a pro rata share of the total number of Shares available under the 2004 Plan. All Options granted under the 2004 Plan shall be at an Option price equal to the Fair Market Value of Shares subject to the Option on the date the Option is granted.

As of the date of the annual meeting of stockholders in each year after 2004 that the 2004 Plan was in effect, as provided in Section V, each independent director then elected or continuing in office who had previously received a stock option grant pursuant to Section III (a) will be issued, without the exercise of the discretion of any person or persons and without payment, 875 Shares (adjusted for the 2006 reverse stock split) of the Company’s fully paid and non-assessable Shares of Common Stock; provided, however, for independent directors elected since the September 2009 annual stockholders meeting, the annual grant was increased to 2,000 shares for each independent director other than the Chairman and in the case of the independent director designated as Chairman, the annual grant was increased to 4,000 shares on March 24, 2010; provided further, that for fiscal year 2010, the grant for

12

independent directors was adjusted to one-half of the 875 share annual grant heretofore approved plus one-half of the new independent director annual grant of 2,000 shares, and in the case of the Chairman of the Board one-half of the new annual grant of 4,000 shares. If, as of any annual meeting date there are not sufficient Shares available under the 2004 Plan to allow the grant to each eligible independent director of Shares or Options pursuant to Section III (a) for the number of shares provided herein, each eligible independent director will receive Shares or Options for a pro rata share of the total number of Shares available under the 2004 Plan. All Shares granted under Section III(d) are non-transferable for six months following the grant date. The entire 2004 Plan as Amended, Reformed and Restated was filed as Exhibit 10.1 to the Company’s periodic report on SEC Form 10Q filed November 5, 2010.

All stock options granted under the 2004 Plan are will “non-qualified stock options”. The 2004 Plan makes no commitment or guarantee that any federal, state or local tax treatment will apply or be available to any non-employee director participating or eligible to participate in the 2004 Plan.  If the Company determines that tax withholding is required, the Company shall require the Participant to remit to the Company an amount sufficient to satisfy any applicable federal, state and local withholding tax requirements prior to the delievery of any certificate or certificates for shares.

The Board has increased the number of independent directors from four to five in order to broaden the experience and diversity of the Board of Directors.  The Board requests stockholder approval to increase by 125,000 shares to a total of 200,000, the number of shares available for possible grant under the 2004 Plan. The 2004 Plan expires on August 15, 2014.

2004 Plan Benefits as Proposed to be Amended

(1)          As of the date of the annual meeting of stockholders, each newly elected independent director then elected will also be granted a 10-year stock option, which vests and is exercisable six months from date of grant, to purchase 1,000 shares of the Company’s common stock at the market price on that date.

(2)          As of the date of the annual meeting of stockholders, each independent director then elected will be granted 2,000 shares of the Company’s common stock fully paid and non-assessable.  The Chairman of the Board will be granted 4,000 shares.

(3)          All options under the 2004 Plan are granted at the Fair Market Value (closing price) of the Company’s common stock on the date of grant and are exercisable for an equivalent number of shares of the Company’s common stock.  The closing price of Company’s common stock on July 8, 2011, the latest practicable date, was $3.55 per share.

Required Vote

The proposal will be approved if a quorum is present and the number of votes cast in favor exceeds fifty (50%) of the issued and outstanding stock of the Company.

The Board of Directors unanimously recommends a vote FOR amendment of the 2004 Independent Director Stock Option and Restricted Stock Grant Plan to increase by 125,000 shares to a total of 200,000 shares the amount of the Company’s common stock authorized for issuance under the 2004 Independent Director Stock Option and Restricted Stock Grant Plan.

PROPOSAL FOUR

Ratification of Selection of Independent Registered Public Accounting Firm

The firm of Grant Thornton LLP has served as the Company’s independent registered public accounting firm for the past three fiscal years.  The Audit Committee has selected, and the Board of Directors has approved, the firm to continue in this capacity for the current fiscal year ending March 31, 2012. A representative of Grant Thornton LLP is expected to attend the annual meeting with the opportunity to make a statement and to respond to appropriate questions from stockholders present at the meeting. Although it is not required to do so, the Company wishes to provide stockholders with the opportunity to indicate their approval of the selection of the independent registered public accounting firm and accordingly is submitting a proposal to ratify the selection of Grant Thornton LLP.  If the stockholders should fail to approve this proposal, the Board of Directors will consider the selection of another independent registered public accounting firm.

The Board of Directors unanimously recommends that stockholders vote FOR ratification of Grant Thornton LLP to serve as the Company’s independent registered public accounting firm for the year ending March 31, 2012.

COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT

Section 16(a) of the Act of 1934, requires the Company’s directors, executive officers, and beneficial owners of more than 10% of a registered class of the Company’s equity securities, (collectively “Insiders”) to file reports with the SEC and the National Association of Securities Dealers, Inc. disclosing direct and indirect ownership of Common Stock and other equity securities of the Company and reports of changes in such ownership.

Based solely on review of copies of Section 16(a) reports received by the Company, and written representations by Insiders that no other reports were required by the SEC, the Company believes Insiders have complied with all Section 16(a) filing requirements for the fiscal year ended March 31, 2011, except that Forms 4 filed by Brent D.

Compensation Discussion

Who is responsible for determining appropriate executive compensation?

The Compensation Committee has the responsibility for recommending the total compensation program for the Company and its subsidiaries, subject to the approval of the Board. This included determining compensation for the past fiscal year 2011, as well as for the current fiscal year 2012, for the Cyanotech Corporation Named Executive Officers (“NEO’s”) who are the individuals named in the Summary Compensation Table herein: (1) Brent D. Bailey, President and Chief Executive Officer since January 11, 2011; (2) Deanna L. Spooner, Chief Financial Officer, Vice President-Finance and Administration, Secretary and Treasurer of the Company; (3) Gerald R. Cysewski, Ph.D., Executive Vice President and Chief Scientific Officer, (4) Glenn D. Jensen, Vice President-Operations and (5) Robert J. Capelli, Vice President-Sales and Marketing; and (6) David I. Rosenthal, Interim President and Chief Executive Officer of the Company until January 10, 2011.

What are the objectives of the Company’s compensation programs?

The goals of the Company’s compensation program are to align compensation with business objectives and performance, and to enable the Company to attract, motivate and retain executives of outstanding ability, potential and drive commensurate with the size and development requirements of the Company. Key components include:

·               The Company pays competitively with comparable small companies, the operators of which are based in Hawaii, with which the Company competes for talent. To ensure that pay is competitive, the Company compares its pay practices with these companies and sets its pay parameters based in part on this review.

·               The Company maintains annual incentive opportunities sufficient to provide motivation to achieve specific operating goals and to generate rewards that being total compensation to competitive levels.

·               The Company provides stock options for executive officers to ensure that they are motivated over the long term to respond to the Company’s business challenges.

The Compensation Committee endeavors to balance Company needs and values with the employees’ needs and believes that it is important that the Committee maintain this relationship.

What are the compensation programs designed to reward?

The Company’s compensation programs are designed to recognize and reward executives for the Company’s annual and long-term performance and for individual performance that enhance shareholder value. To that end:

·               Company Performance.   The Compensation Committee considers each executive’s overall contribution to the Company’s long-term and short-term results and projections in relation to the Company goal of achieving sustainable profitability from sales of its products.

·               Individual Performance.   The Company has a small executive team of talented individuals with clear divisions of responsibility for achieving the Company’s goals. The Compensation Committee evaluates the Chief Executive Officer as a committee or in conjunction with the other independent members of the Board of Directors (as determined by the full Board). That evaluation entails a review of the Chief Executive Officer’s Letter Agreement and his performance and progress towards achieving sustainable profitability through improved long-term and short-term results attributable directly and indirectly to his efforts. The Compensation Committee or the full Board (excluding the Chief Executive Officer) acting with the Committee or upon its recommendations also considers relative shareholder return over the same period and chief executive compensation for similar-sized companies with similar results within the relevant geographic and industry area.

For other NEO’s, the Compensation Committee reviews and considers whether to approved a performance assessment and base salary recommendation from the Chief Executive Officer. The performance evaluations of these executives are based on an the Company’s success in achieving short-term and long-term results and projections in relation to the Company goal of achieving sustainable profitability from sales of its products; in addition to performance toward specific departmental goals established annually and approved by the Compensation Committee

What are the elements of executive compensation?

The elements of the Company’s executive compensation include:

·                  Base salary and bonus, if awarded

·                  Incentive stock option grants

·                  Commission component for Vice President-Sales (through March 31, 2011 only)

18

Table of Contents

How is base salary determined?

The base salaries of the executive officers are determined initially on the basis of one or more salary surveys conducted by third parties as well as research conducted by the Company’s Manager of Human Resources of local and national companies from public information such as filings with the SEC. Based on such surveys, the executive officers’ salaries are set within the ranges of the surveys targeted at the median; the exact level is determined after the Committee considers the experience and capability of the executive officer, the level of responsibility and the needs of the Company.

What were the base salary increases for fiscal year 2011?

There were no base salary increases during fiscal year 2011.

Are bonuses paid to executive officers?

The Committee believes that, as a general rule, annual compensation in excess of base salaries should be dependent on the employee’s performance and the Company’s performance, and should be awarded based on performance reviews and recommendations of the Chief Executive Officer to the Committee and in the discretion of the Board.  Accordingly, each fiscal year, the Committee reviews and approves a cash incentive bonus plan designed to motivate executive officer and key personnel to achieve the financial and operational objectives of the Company.

The financial goals are established in part on the basis of an annual operating plan developed by management and approved by the Board of Directors.  The annual operating plan is designed to maximize profitability, within the constraints of economic and competitive conditions, some of which are outside the control of the Company, and is developed on the basis of:  (i) the Company’s performance in the prior year; (ii) estimates of sales revenue for the plan year based upon recent market conditions and trends and other factors which, based on historical experience, are expected to affect the level of sales that can be achieved; (iii) historical operating cost and cost savings that management believes can be achieved; and (iv) competitive conditions faced by the Company. Taking all of these factors into account, financial targets for key financial performance indicators such as Net Income, Gross Margin and Net Income are established.

Additionally, specific performance measures are established in areas of strategic planning, leadership, and operations as appropriate to the executive’s area of management responsibility.  Such goals support and compliment the financial goals of the Company and allow executives to achieve meaningful results even when the Company’s overall profitability is challenged.

As a result of such performance-based criteria, executive compensation, and the proportion of each executive’s total cash compensation that is represented by incentive or bonus income, may increase in those years in which the Company achieves the anticipated level of growth and profitability. On the other hand, in years in which the Company experiences less than anticipated growth, bonuses and total executive compensation should be lower or not awarded and total executive compensation should consequently be lower.

As approved under the terms and conditions of the Company’s agreement with its senior debt holder, and as reported herein, the Company’s Officers were awarded the following bonuses:  Chief Financial Officer and Vice President Administration, $36,656; Executive Vice President and Chief Scientific Officer, $33,598; Vice President—Operations, $26,171; and Vice President—Sales and Marketing, $26,621.

What is the Company’s incentive stock option program?

The 2005 Stock Option Plan (the “2005 Plan”) rewards select executives and key employees as an incentive for them to join or remain in the service of the Company. The Compensation and Stock Option Committee administers the Plan.

How does the Company award stock option grants?

The Committee generally intends to make stock option grants on an annual basis. Each grant is designed to align the interests of the executive officers with those of the stockholders and provide each individual with a significant incentive to manage the Company from the perspective of an owner with an equity stake in the business. Each grant generally allows the executive officer to acquire shares of the Company’s Common Stock at a fixed price per share (usually the market price on the date of grant) over a specified period of time (up to 10 years), thus providing a return to the executive officer only if he or she remains in the employ of the Company and the market price of the shares appreciate over the option term. The size of the option grant to each executive officer generally is set at a level that is intended to create a meaningful opportunity for stock ownership based upon the individual’s current position with the Company, but also taken into account are the size of comparable awards made to individuals in similar positions in the industry as reflected in external surveys, the individual’s potential for future responsibility and promotion over the option term, the individual’s personal performance in recent periods and the number of options held by the individual at the time of grant. Generally, as an executive officer’s level of responsibility increases, a greater portion of his or her total compensation will be dependent upon Company performance and stock price appreciation rather than base salary. The relative weight given to these factors varies with each individual, in the sole discretion of the Committee.

What perquisites and other personal benefits do executive officers have?

The President and Chief Executive Officer receives commuting expenses to Hawaii including airfare, transportation to and from the local airport, parking fees, etc.; housing, transportation, meals and incidentals while working in Hawaii.

Do executive officers have change-in-control agreements?

Provisions are contained in the 2005 Stock Option Plan concerning acceleration of stock options when a Change in Control or a Corporate Transaction, as defined in such Plan, occurs unless the outstanding options are assumed or replaced by the successor corporation with comparable, equalized options or a cash incentive program in accordance with the terms of the 2005 Stock Option Plan.

How was the Chief Executive Officer’s compensation determined last fiscal year?

The compensation for Mr. Rosenthal, the Company’s Interim Chief Executive Officer was determined by the Committee and was set forth in an Independent Consulting Agreement effective February 27, 2010 which incorporates terms outlined in a CEO Transition Plan. In consideration for the services outlined in the Plan, Mr. Rosenthal received $23,000 per month consulting fees plus taxes in addition to perquisites including commuting expenses to Hawaii: airfare, transportation to and from the local airport, parking fees, etc.; housing, transportation, meals and incidentals while working in Hawaii. The Committee evaluated the indefinite nature of the term of the agreement, Mr. Rosenthal’s knowledge of the Company as a long-term director of the Company and his professional expertise in establishing the monthly compensation.

The compensation payable to Mr. Bailey, the Company’s current President and Chief Executive Officer was determined by the Committee and was set forth in a Letter Agreement of Employment stating terms of employment dated November 5, 2010 with employment effective January 11, 2011.  Base salary was set at a level which the Board felt would be competitive with the base salary levels in effect for chief executive officers at similarly-sized companies within the industry of $300,000 annually, plus eligibility for performance-based bonuses equal to 50% of the base salary for each fiscal year of the seven year contract.  Additionally, stock options to purchase shares equivalent to approximately 13.5% of the Company’s outstanding common stock at January 11, 2011 were also granted pursuant to the Letter Agreement of Employment.  Mr. Bailey also receives perquisites such as commuting expenses to Hawaii including airfare, transportation to and from the local airport, parking fees, etc.; housing, transportation, meals and incidentals while working in Hawaii.

Report of the Audit Committee of the Board of Directors

The Audit Committee, which met four (4) times in fiscal 2011, reviewed and discussed the Company’s audited financial statements with management.

The Audit Committee also received written disclosures and the letter from Grant Thornton required by Independence Standards Board Standard No. 1, which relates to the independent registered public accounting firm’s independence from the Company and its related entities.

The Audit Committee is governed by the Audit Committee Charter adopted by the Board of Directors, a current copy of which is available on the Company’s website at www.cyanotech.com. Pursuant to such Charter, the Audit Committee has the following primary responsibilities:

The firm of Grant Thornton, an independent registered public accounting firm, served as the Company’s independent registered public accounting firm for the fiscal years ended March 31, 2011, 2010 and 2009. As stated in Proposal Two, the Audit Committee has selected and the Board has approved Grant Thornton to serve as the Company’s independent registered public accounting firm for the fiscal year ended March 31, 2012.
