The Annual Meeting will be held at our corporate offices, located at 855 Jarvis Drive, Suite 100, Morgan Hill, California 95037. We intend to mail this proxy statement and accompanying proxy card on or about May 3, 2004 to all shareholders entitled to vote at the Annual Meeting. Solicitation We will bear the entire cost of solicitation of proxies, including preparation, assembly, printing and mailing of this proxy statement, the proxy card and any additional information furnished to shareholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding in their names shares beneficially owned by others to forward to such beneficial owners. We may reimburse persons representing beneficial owners of common stock for their costs of forwarding solicitation materials to such beneficial owners. Original solicitation of proxies by mail may be supplemented by telephone, telegram or personal solicitation by directors, officers or other regular employees of the company. No additional compensation will be paid to directors, officers or other regular employees for such services. Voting Rights and Outstanding Shares Only holders of record of common stock at the close of business on March 31, 2004 (the "Record Date") will be entitled to notice of and to vote at the Annual Meeting. At the close of business on March 31, 2004 we had outstanding and entitled to vote 3,549,642 shares of common stock. Each holder of record on the Record Date will be entitled to one vote for each share held on all matters to be voted upon. With respect to the election of directors, shareholders may exercise cumulative voting rights. Under cumulative voting, each holder of common stock will be entitled to five votes for each share held. Each shareholder may give one candidate all the votes that shareholder is entitled to cast or may distribute his or her votes among as many candidates as the shareholder chooses. However, no shareholder will be entitled to vote for a candidate unless the candidate's name has been placed in nomination prior to the voting. No shareholder will be entitled to vote cumulatively unless at least one shareholder has given notice at the meeting, prior to the voting, of his or her intention to cumulate votes. Unless the proxyholders are otherwise instructed, shareholders, by means of the accompanying proxy, will grant the proxyholders discretionary authority to cumulate votes. All votes will be tabulated by the inspector of election appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes. Abstentions and broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether a matter is approved. Revocability of Proxies Any person giving a proxy pursuant to this solicitation has the power to revoke it at any time before it is voted. It may be revoked by filing with our Secretary at our principal executive office, 855 Jarvis Drive, Suite 100, Morgan Hill, California 95037, a written notice of revocation or a duly executed proxy bearing a later date, or it may be revoked by attending the meeting and voting in person. Attendance at the meeting will not, by itself, 1 revoke a proxy. Please note, however, that if a shareholder's shares are held of record by a broker, bank or other nominee and that shareholder wishes to vote at the meeting, the shareholder must bring to the meeting a letter from the broker, bank or other nominee confirming the shareholder's beneficial ownership of the shares and that the broker, bank or other nominee is not voting the shares at the meeting. Shareholder Proposals The deadline for submitting a shareholder proposal for inclusion in our proxy statement and form of proxy for our 2005 annual meeting of shareholders pursuant to Rule 14a-8 of the Securities and Exchange Commission 120 calendar days before the one year anniversary of the date of the proxy statement, or January 5, 2005. Shareholder proposals may be presented at the 2005 annual meeting the shareholders only if we have received adequate notice of such proposals at our principal executive offices no later than January 5, 2005. Proposals we receive after that date will be considered untimely and will not be presented at our 2005 annual meeting. Unless a shareholder who wishes to bring a matter before the shareholders at our 2005 annual meeting of shareholders notifies us of such matter prior to January 5, 2005, management will have discretionary authority to vote all shares for which it has proxies in opposition to such matter.

PricewaterhouseCoopers LLP has audited our financial statements since Castelle's inception in 1987. Representatives of PricewaterhouseCoopers LLP are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions. Shareholder ratification of the selection of PricewaterhouseCoopers LLP as our independent auditors is not required by our Bylaws or otherwise. However, the Board is submitting the selection of PricewaterhouseCoopers LLP to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the Audit Committee and the Board will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee and the Board in their discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of Castelle and its shareholders.

Unless otherwise indicated in the footnotes to this table and subject to community property laws where applicable, we believe that each shareholder named in this table has sole voting and investment power with respect to the shares indicated as beneficially owned. Applicable percentages are based on 3,549,642 shares outstanding on March 31, 2004, the record date for this proxy, plus options exercisable within 60 days of March 31, 2004, for the person being measured.

Non-employee directors are also reimbursed for their expenses incurred in connection with attending Board meetings. Equity Compensation In 2003, each non-employee director received stock option grants under the 2002 Equity Incentive Plan (the "2002 Option Plan"), which superceded the 1995 Non-Employee Directors' Stock Option Plan, as amended through February 2000, and the 1988 Equity Incentive Plan, as amended through 1998 (collectively as the "Prior Option Plan"). Directors receive non-qualifying stock options under the 2002 Option Plan and Code. The 2002 Option Plan provides that each non-employee member of the Board of Directors, upon initial election to the Board, is automatically granted an option to purchase 10,000 shares of common stock at an exercise price equal to the then-current fair market value per share of our common stock. This initial option grant vests monthly in 12 equal installments, beginning one month after the date of grant provided that the optionee has continuously served as a director. On April 1 of each year (or the next business day should such date be a legal holiday), each member of the Board who is eligible for participation in the 2002 Option Plan is automatically granted an option to purchase 5,000 shares of common stock at an exercise price equal to the then-current fair market value per share of our common stock, without further action by us, the Board or our shareholders. This annual grant to non-employee members of the Board under the 2002 Option Plan vests monthly in 12 equal installments, beginning one month after the date of grant provided that the optionee has, during the entire period prior to such vesting date, continuously served as a director. The exercise price of options granted under the 2002 Option Plan is 100% of the fair market value of the common stock on the date of the option grant. The term of options granted under the 2002 Option Plan may not be longer than ten years. During 2003, we granted to each of Messrs. Hambrecht, Tierney and Rich options to purchase 5,000 shares at exercise prices of $2.96 per share under the 2002 Option Plan. In March 2004, we granted to Mr. Smith options to purchase 10,000 shares at an exercise price of $4.50 upon his initial election to the Board. The exercise prices were equal to the respective fair market values of such common stock on the date of grant (based upon the closing sale price reported on the NASDAQ SmallCap Market for the date of grant). Options which remain outstanding under the Prior Option Plan will accelerate under certain circumstances. In the event of a merger of Castelle with or into another corporation or a consolidation, acquisition of assets or other change-in-control transaction, vesting of option grants under the Prior Option Plan is accelerated and the option will terminate if not exercised prior to the consummation of the transaction. Compensation of Executive Officers Summary of Compensation The following table shows for the years ended December 31, 2003, 2002 and 2001, compensation awarded or paid to, or earned by, our Chief Executive Officer and the four other most highly compensated executive officers at December 31, 2003 whose total annual salary and bonus exceeded $100,000 (the "Named Executive Officers"): 8 SUMMARY COMPENSATION TABLE Long-Term Compensation Annual Compensation Awards Name and Principal Securities Underlying Position Year Salary Bonus ($)(1) Other($)(3) Options (#) - -------- ---- ------ --------- ----------- ----------- Scott C.

(2) The exercise price is equal to 100% of the fair market value of common stock at the date of the grant. (3) The potential realizable value is calculated based on the assumption that the stock price on the date of grant appreciates from the date of grant at the indicated annual rate compounded annually for the entire term of the option and that the option is exercised and sold on the last day of its term for the appreciated stock price. The 5% and 10% assumed rates of appreciation are derived from the rules of the U.S. Securities and Exchange Commission and do not represent our estimate or projection of future common stock prices.

EMPLOYMENT SEVERANCE AND CHANGE OF CONTROL AGREEMENTS In November 1998, Castelle entered into employment and severance agreements with Donald L. Rich, both of which terminated in April 2002 following Mr. Rich's decision to retire as our Chief Executive Officer. Because Mr. Rich's retirement was entirely voluntary, he was not entitled to receive further payments under either his employment agreement or his severance agreement. In April 2002, Castelle entered into an employment agreement with Scott C. McDonald, pursuant to which Mr. McDonald agreed to serve as our Chief Executive Officer. The employment agreement is not for a specified term and is terminable at will or without cause at any time upon written notice, subject to the conveyance of certain severance benefits to Mr. McDonald upon termination, as described below. The employment agreement provided for an annual base salary of $200,000, plus an annual bonus of up to a sum of $100,000, if performance criteria are met, or above $100,000 in the discretion of the Compensation Committee if performance criteria are exceeded. Mr. McDonald's annual base salary was adjusted by the Compensation Committee to $225,000 as of his one year anniversary date in April 2003, and his bonus arrangement was also revised (see "Report of the Compensation Committee of the Board of Directors on Executive Compensation" below). Mr. McDonald was originally granted options to purchase 300,000 shares of the common stock under our Prior Option Plan. The first option became one quarter vested after six months, with the remainder vesting over the next eighteen months. The second option becomes fully vested after three years. In 2003, Mr. McDonald received a grant to purchase additional shares of the company (see "Report of the Compensation Committee of the Board of Directors on Executive Compensation" below). We have also entered into a severance and transition benefit agreement with Mr. McDonald, pursuant to which we agreed that if we terminate Mr. McDonald without cause or if Mr. McDonald terminates his employment voluntarily for good cause, we are required to pay him 100% of his annualized salary and maintain the medical benefits conveyed to him for one year. In addition, 50% of Mr. McDonald's unvested options will become immediately vested. The agreement allows Mr. McDonald to terminate his employment for good cause if his responsibilities are materially diminished, base pay is reduced or potential bonus payments are materially reduced, the company fails to continue any benefit plan in which Mr. McDonald is participating without comparable replacement, our corporate headquarters is relocated more than 20 miles from its current location or we breach this agreement or Mr. McDonald's employment agreement. No payment will be due if Mr. McDonald is dismissed for cause. In the event of a change of control of Castelle, Mr. McDonald is eligible for a lump sum payment equal to six months of his base salary, in addition to any benefits that may be conveyed to Mr. McDonald upon termination, if he remains with us at least ninety days after a change in control and his employment is subsequently terminated for any reason. 11 COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation Committee currently consists of Robert H. Hambrecht and Peter R. Tierney, neither of whom are officers or employees. None of our executive officers currently serves or has served as a member of the Board of Directors or the Compensation Committee of any entity, or any executive officer of which serves on our Board of Directors or Compensation Committee, except as provided below. Mr. Scott C. McDonald served on the Compensation Committee of the Board of Digital Power Corporation ("Digital Power") at a time when Mr. Robert O. Smith served as Digital Power's Chief Executive Officer. Mr. Smith left the employment of Digital Power in November, 2001. Mr. Smith does not serve on our Compensation Committee.

Our executive compensation program is administered by the Compensation Committee of the Board of Directors. The Committee currently consists of Robert H. Hambrecht and Peter R. Tierney. Each is a non-employee director within the meaning of Section 16 of the Securities Exchange Act of 1934 and an "outside director" within the meaning of Section 162(m) of the Internal Revenue Code. None of the members of the Compensation Committee has any interlocking relationships as defined by the Securities and Exchange Commission. General Compensation Philosophy The Committee is responsible for determining compensation policies for our executive officers, including any stock-based awards to such individuals under the Prior Option Plan and the 2002 Option Plan. In determining executive officer compensation, the Compensation Committee considers corporate performance against our objectives. The Compensation Committee structures executive compensation packages with two objectives: o to ensure that the compensation and incentives provided to the executive officers are closely aligned with our financial performance and shareholder value; and o to attract and retain, through a competitive compensation structure, those key executives critical to the long-term success of the company For 2003, our executive compensation program included the following components: (i) base salary, (ii) options to purchase shares of common stock, and (iii) quarterly incentives in the form of cash bonuses. Executive Compensation Stock Options. In addressing the first objective, the Compensation Committee utilizes stock option grants to executive officers to tie a portion of executive officer compensation directly to our stock price performance. The Compensation Committee believes that the grant of an equity interest in the company serves to link management interests with shareholder interests and to motivate executive officers to make decisions that are in the best interests of Castelle and the shareholders. The Board considers stock option grants to executive officers based on various factors, including (i) each officer's responsibilities, (ii) any changes in such responsibilities, (iii) past option grants and each officer's current equity interest in the company and (iv) individual or corporation performance. In 2003, our executive officers received options to purchase common stock at levels ranging from 5,000 to 150,000 shares. Base Salary and Cash Bonuses. The second objective of the overall executive compensation policy is addressed by a salary and bonus policy which is based on: o consideration of the salaries and total compensation of executive officers in similar positions with comparable companies in the industry; o the qualifications and experience of each executive officer; o the company's financial performance during the past year; and o each officer's performance against objectives related to their areas of responsibility. 13 The Compensation Committee periodically reviews individual base salaries of executive officers, and adjusts salaries based on individual job performance and changes in the officer's duties and responsibilities. In making salary decisions, the Board exercises its discretion and judgment based on these factors. No specific formula is applied to determine the weight of each factor, although the mix among the compensation elements of salary, cash incentive and stock options are biased toward stock options to emphasize the link between executive incentives and the creation of shareholder value as measured by the equity markets. Consequently, salaries and cash incentives may be in the low-range as compared to the comparable companies in the industry while stock options may be in the mid to high-range compared to comparable companies. The Chief Executive Officer provides the Board with recommendations for individual executive officers based upon an evaluation of their performance against objectives and responsibilities. The base salaries paid to three of our executive officers were increased in 2003 ranging from $10,000 to $25,000 per annum. The Compensation Committee believes that another key element of executive compensation should be the variable portion provided by cash incentive plans. The Board of Directors sets annual performance objectives for executives of the company, which are administered quarterly by the Chief Executive Officer. Our executive officer compensation plan is designed such that if we meet our stated objectives, executive officers receive the cash incentive part of their compensation. If we perform below our stated objectives, the cash incentive portion of the executive's compensation is significantly reduced, and may be eliminated altogether if performance is below defined thresholds. A substantially smaller portion of some executives' incentive compensation is based on performance against individual objectives. The actual cash bonus earned in 2003 by executive officers depended upon the extent to which our objectives were achieved. Because we obtained a certain percentage of such quarterly performance objectives, cash bonuses ranging from $50,000 to $137,253 were paid to executive officers for services performed during 2003. Chief Executive Officer The Compensation Committee uses similar factors to those described above for the executive officers in setting the annual salary, stock option grant and cash incentives awarded to our Chief Executive Officer, Scott C. McDonald. Mr. McDonald is eligible to receive quarterly performance bonuses, in a total amount of up $150,000 per year. Payment of $75,000 or fifty percent (50%) of such bonus is contingent upon the company remaining profitable on an Earnings per Share basis. The remaining $75,000 or fifty percent (50%) of such bonus shall be granted in proportion to the company meeting the profit performance criteria set forth within the financial plans approved by the Compensation Committee and Board of Directors. In the event Mr. McDonald exceeds the performance criteria established by the Committee and Board in a given year (as determined by the Compensation Committee), Mr. McDonald will be eligible to earn bonuses that exceed a total of $150,000 for the year. Mr. McDonald was awarded cash bonuses totaling $137,253 in 2003. The Board awarded Mr. McDonald stock option grants totaling 150,000 shares during 2003. Internal Revenue Code Section 162(m) Limitation Section 162(m) of the Internal Revenue Code, limits the tax deduction to $1 million for compensation paid to certain executive officers. Compensation in excess of $1 million may be deducted if it is performance-based compensation within the meaning of the Code. The Committee has determined that stock options granted under our Prior Option Plan with an exercise price at least equal to the fair market value of the common stock on the date of grant should, where practicable, be treated as "performance-based compensation," and the Prior Option Plan contains provisions designed to allow compensation recognized by an executive officer as a result of the grant of a stock option to be deductible by the company. 2003 Compensation Committee ROBERT H. HAMBRECHT PETER R. TIERNEY 14 REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS (The information contained in this Report of the Compensation Committee shall not be deemed to be "soliciting material" or "filed" or incorporated by reference in future filings with the Securities and Exchange Commission, or subject to the liabilities of Section 18 of the Securities Exchange Act of 1934, whether made before or after the date hereof and irrespective of any general incorporation language in any filing, except to the extent that Castelle specifically incorporates it by reference into a document filed under the Securities Act of 1933 or the Securities Exchange Act of 1934.) The Audit Committee has the responsibility, under delegated authority from the Board of Directors, for providing independent, objective oversight of our corporate accounting and reporting practices as well as the quality and integrity of our financial statements and reports. The Audit Committee acts under a written charter adopted and approved by the Board of Directors. The Audit Committee was comprised of three non-employee directors (see section "Board Committees and Meetings" above). Management is responsible for our internal controls and the financial reporting process. The independent auditors are responsible for performing an independent audit of our financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Audit Committee's responsibility is to monitor and oversee these processes. In this context, the Audit Committee has met and held discussions with management and the independent auditors. Management represented to the Audit Committee that our consolidated financial statements were prepared in accordance with generally accepted accounting principles, and the Audit Committee has reviewed and discussed our consolidated financial statements for the year ended December 31, 2003 with management and the independent auditors. In addition, the Audit Committee has discussed with the independent auditors the matters required to be discussed by the Statement on Auditing Standards No. 61, Communication with Audit Committees, as amended, has received and reviewed the written disclosures and the letter from the independent public auditors required by Independence Standard No. 1, Independence Discussions with Audit Committees, as amended, has reviewed and negotiated applicable audit fees, has discussed with the independent auditors their independence, and has undertaken the additional communications, review and other requirements and activities mandated by those provisions of the Sarbanes-Oxley Act of 2002 which have been adopted.

The Board has an Audit Committee, a Compensation Committee, an Executive Committee and a Nominating Committee. During 2003, each Board member attended 75% or more of the aggregate number of meetings of the Board and committees on which he served. The Audit Committee meets at least annually with our management and independent auditors to review the results of the annual audit and discuss the financial statements, recommends to the Board the independent auditors to be retained, reviews, negotiates and approves audit fees, oversees the independence of the independent auditors, evaluates the independent auditors' performance and receives and considers the independent auditors' comments as to controls, adequacy of staff and management performance and procedures in connection with audit and financial controls. The Audit Committee pre-approves all audit services to be performed by any accounting firm, including our independent auditors, and all non-audit services to be provided by our independent auditors, and provides the Board of Directors such additional information and materials as it may deem necessary to make the Board aware of significant financial, accounting, and internal control matters that require the attention of the Board. During 2003, the Audit Committee was composed of three non-employee directors, Messrs. Hambrecht, Rich and Tierney. Mr. Hambrecht serves as Chairman of the Audit Committee. The Board of Directors has determined that Messrs. Hambrecht and Tierney are independent for Audit Committee purposes pursuant to the applicable Marketplace Rules of The NASDAQ Stock Market and Rule 10A-3 under the Securities Exchange Act of 1934. While Mr. Rich is not independent for Audit Committee purposes, he has been a member of the Audit Committee pursuant to an exception to the applicable Marketplace Rules of The NASDAQ Stock Market that will expire at the time of the impending Annual Meeting of Shareholders, and accordingly his last day of service on the Audit Committee will be May 28, 2004. At that time, the Board intends to appoint Mr. Robert O. Smith to the Audit Committee. Although the Board of Directors has determined that Mr. Smith will not be considered independent for audit committee purposes at the time of his initial appointment, the Board believes that Mr. Smith will become independent under the applicable Marketplace Rules of The NASDAQ Stock Market and Rule 10A-3 under the Securities Exchange Act of 1934, in November 2004. Until such time, Mr. Smith will serve on the Audit Committee under an exception to the applicable rules of The NASDAQ Stock Market. The Board has determined that Mr. Smith's membership on the Audit Committee is required by and in the best interests of the company and its shareholders due to Mr. Smith's expertise, knowledge and experience in the industry and his knowledge of financial and accounting matters. The Board of Directors has determined that each member is qualified as an audit committee financial expert pursuant to Item 401(h) of Regulation S-K and as a financially sophisticated audit committee member under Rule 4350(d)(2)(A) of the Marketplace Rules of The NASDAQ Stock Market. The Audit Committee acts pursuant to a written charter adopted by the Board, which is attached to this Proxy Statement as Appendix A. The Audit Committee met four times during 2003 and acted once by unanimous written consent. The Compensation Committee makes recommendations concerning salaries and incentive compensation, authorizes stock option awards to employees and consultants under our stock option plans and otherwise determines compensation levels and performs such other functions regarding compensation as the Board may delegate. The Compensation Committee is composed of two outside directors: Messrs. Hambrecht and Tierney. Mr. Tierney serves as the Chairman of the Compensation Committee, and the Board of Directors has determined that each of the members of the Compensation Committee is independent as defined in the applicable Marketplace Rules of The NASDAQ Stock Market. The Compensation Committee held one meeting and acted two times by unanimous written consent during 2003 The Executive Committee makes recommendations to the Board of Directors on projects assigned by the Board of Directors. The Executive Committee is composed of three directors, Messrs Rich, Hambrecht and 17 McDonald. The Executive Committee held no meetings during 2003 and took no action by unanimous written consent. The Nominating Committee identifies, evaluates and nominates candidates for consideration for appointment or election as members of the Board, makes recommendations regarding the structure and composition of the Board and committees of the Board, and oversees the evaluation of the Board and committees of the Board. The Board of Directors has adopted a written charter for the Nominating Committee, a current copy of which is available on our website at http://www.castelle.com/corporate/governance.htm, under the "Investor Relations" page. Please note that information on the company web site is not incorporated by reference into this Proxy Statement. The Nominating Committee is composed of two directors, Messrs. Hambrecht and Tierney. Mr. Tierney serves as the Chairman of the Nominating Committee, and the Board of Directors has determined that each of the members of the Nominating Committee is independent as defined in the applicable Marketplace Rules of The NASDAQ Stock Market. The Nominating Committee was formed in 2004, held no meetings during 2003 and took no action by unanimous written consent. DIRECTOR NOMINATION In evaluating potential director candidates, the Nominating Committee considers the appropriate balance of experience, skills and characteristics required of the Board of Directors and seeks to ensure that at least a majority of the directors are independent under the applicable Marketplace Rules of The NASDAQ Stock Market, Inc. The Nominating Committee selects director nominees based on their personal and professional integrity, depth and breadth of experience, ability to make independent analytical inquiries, understanding of our business, willingness to devote adequate attention and time to duties of the Board of Directors and such other criteria as is deemed relevant by the Nominating Committee. Castelle believes that the backgrounds and qualifications of the directors, considered as a group, should provide a diverse mix of experience, knowledge and skills. In identifying potential director candidates, the Nominating Committee relies on recommendations made by current directors and officers. In addition, the Nominating Committee may engage a third party search firm to identify and recommend potential candidates. Finally, the Nominating Committee will consider candidates recommended by shareholders. Any shareholder wishing to recommend a director candidate for consideration by the Nominating Committee must provide written notice to the Corporate Secretary at our principal executive offices located at 855 Jarvis Drive, Suite 100, Morgan Hill, CA 95037 by the time of the deadline set forth below. Any such notice should clearly indicate that it is a recommendation of a director candidate by a shareholder and must set forth (i) the name, age, business address and residence address of the recommended candidate, (ii) the principal occupation or employment of such recommended candidate, (iii) the class and number of shares of the corporation which are beneficially owned by such recommended candidate, (iv) a description of all understandings or arrangements between the shareholder and the recommended candidate and any other person or persons pursuant to which the recommendations are to be made by the shareholder and (v) any other information relating to such recommended candidate that is required to be disclosed in solicitations of proxies for the election of directors. In addition, such notice must contain (i) a representation that the shareholder is a holder of record of Castelle stock entitled to vote at such meeting, (ii) the name and address, as they appear on our books, of the shareholder proposing such nomination, (iii) the class and number of shares of our common stock that are beneficially owned by such shareholder, (iv) any material interest of the shareholder in such recommendation and (v) any other information that is required to be provided by the shareholder pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended, in such shareholder's capacity as proponent of a shareholder proposal. We require that any such recommendations for inclusion in our proxy materials for our 2005 Annual Meeting of Shareholders be made not later than January 5, 2005 to ensure adequate time for meaningful consideration by the committee. See "Shareholder Proposals" for additional information regarding deadlines for submitting proposals. Properly submitted recommendations will be forwarded to our Nominating Committee for review and consideration. Assuming that a shareholder recommendation complies with the above process and contains the information required above, the Nominating Committee will evaluate a candidate recommended by a shareholder according to its processes and criteria established in its sole discretion. 18 ATTENDANCE AT ANNUAL MEETINGS Castelle invites all of its directors to attend our annual meetings of shareholders. Two directors attended the annual meeting of shareholders held on May 29, 2003. STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS The Board of Directors maintains a process for shareholders to communicate with the Board of Directors or with individual directors. Shareholders who wish to communicate with the Board of Directors or with individual directors should direct written correspondence to our Corporate Secretary at our principal executive offices located at 855 Jarvis Drive, Suite 100, Morgan Hill, CA 95037.

The Corporate Secretary is required to direct certain communications, including all communications regarding personal grievances, administrative matters, the conduct of the company's normal business operations, billing issues, product or service related inquiries, order requests and similar issues to the appropriate individual within the company. The Corporate Secretary will forward all other communications to the Board of Directors, or the Board member addressee, or to the director or committee of the Board appointed to handle such communications, except for communications deemed unduly hostile, threatening, illegal or inappropriate, in which case the Corporate Secretary has the authority to discard the communication or to take appropriate legal action regarding such communication.

Purpose and Authority The Audit Committee (the "Committee") of the Board of Directors (the "Board") of Castelle (the "Company") is appointed by the Board to oversee the accounting and financial reporting processes of the Company and audits of the financial statements of the Company. The Committee's principal functions are to: o monitor the periodic reviews and audits of the adequacy of the accounting and financial reporting processes and systems of internal control that are conducted by the Company's independent auditors and the Company's financial and senior management; o appoint and review, and evaluate the independence and performance of, the Company's independent auditors; and o facilitate communication among the Company's independent auditors and the Company's financial and senior management. The Committee will fulfill these functions primarily by carrying out the activities enumerated in Part IV of this charter. In order to serve these functions, the Committee shall have unrestricted access to Company personnel and documents, shall have authority to direct and supervise an investigation into any matters within the scope of its duties, and shall have authority to engage and determine funding for such independent counsel, experts and other advisers as it determines to be necessary or appropriate to carry out its responsibilities and duties. The Company will provide for appropriate funding, as determined by the Committee, in its capacity as a committee of the Board, for payment of (a) compensation to the public accounting firm engaged for the purpose of rendering or issuing an audit report or performing other audit, review or attest services for the Company; (b) compensation to any advisers employed by the Committee referenced above; and (c) ordinary administrative expenses of the Committee that are necessary or appropriate in carrying out its duties. While the Committee has the responsibilities and powers set forth in this charter, it is not the duty of the Committee to plan or conduct audits or to determine that the Company's financial statements are complete and accurate and are in accordance with generally accepted accounting principles. This is the responsibility of management and the Company's independent auditors. II. Membership All members of the Committee will be appointed by, and shall serve at the discretion of, the Board. Unless a chair is elected by the full Board, the members of the Committee may designate a chair by majority vote of the Committee membership.

IV. Responsibilities and Duties The following shall be the principal recurring processes of the Committee in carrying out its oversight responsibilities.
