The Annual Meeting will be held at our corporate offices, located at 855 Jarvis Drive, Suite 100, Morgan Hill, California. We intend to mail this proxy statement and accompanying proxy card on or about November 25, 2002 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 Castelle. 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 October 24, 2002 (the "Record Date") will be entitled to notice of and to vote at the Annual Meeting. At the close of business on October 24, 2002 we had outstanding and entitled to vote 4,806,044 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 four votes for each share held. Each shareholder may give one candidate all the votes such shareholder is entitled to cast or may distribute such votes among as many such candidates as such 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 3 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 Castelle's 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, 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 2003 annual meeting of shareholders pursuant to Rule 14a-8 of the Securities and Exchange Commission is a reasonable time before we begin to print and mail its proxy materials. Unless a shareholder who wishes to bring a matter before the shareholders at our 2003 annual meeting of shareholders notifies us of such matter prior to a reasonable time before we mail our proxy materials, management will have discretionary authority to vote all shares for which it has proxies in opposition to such matter. 4 Proposal 1 Election Of Directors There are four nominees for the five Board positions presently authorized in our Bylaws. Each director to be elected will hold office until the next annual meeting of shareholders and until his successor is elected and qualified, or until such director's earlier death, resignation or removal. Each nominee listed below is currently a director of Castelle, having been elected by the shareholders and by the Board. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the four nominees named below, with discretionary power with respect to any further nominees and to cumulate votes. In the event that any nominee should be unavailable for election as a result of an unexpected occurrence, such shares will be voted for the election of such substitute nominee as management may propose. Each person nominated for election has agreed to serve if elected and management has no reason to believe that any nominee will be unable to serve. The four candidates receiving the highest number of affirmative votes cast at the meeting will be elected directors of Castelle. The minimum authorized number of directors is five. The Board of Directors currently has one vacancy on the Board of Directors due to the recent resignation of Jack Howard from the Board of Directors of Castelle in connection with our recent share repurchase. Please refer to the section "Certain Relationships and Related Transactions" for more information on this transaction.

BOARD COMMITTEES AND MEETINGS During 2001, the Board of Directors held four meetings and acted by unanimous written consent four times. The Board has an Audit Committee and a Compensation Committee. During 2001, 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 Castelle's 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, 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. During fiscal 2001, the Audit Committee was composed of three non-employee directors: Messrs. McDonald and Hambrecht and Jack L. Howard. The Audit Committee met once during fiscal 2001 and took no action by unanimous written consent. All members of the Audit Committee were independent in fiscal 2001 (as independence is defined by The NASDAQ Stock Market). The Compensation Committee makes recommendations concerning salaries and incentive compensation, awards stock options 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. The Compensation Committee acted once by unanimous written consent during fiscal 2001. REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS 1 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. During fiscal 2001, the Audit Committee was composed of three non-employee directors, whose names appear below. Management is responsible for our internal controls and the financial reporting process. The independent accountants 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. ____________________ 1 The material in this report is not "soliciting material," is not deemed "filed" with the SEC, and is not to be incorporated by reference into any filing of castelle with the SEC under Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. 7 In this context, the Audit Committee has met and held discussions with management and the independent accountants. 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 fiscal year ended December 31, 2001 with management and the independent accountants. 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 accountants required by Independence Standard No. 1, Independence Discussions with Audit Committees, as amended, and has discussed with the independent auditors their independence. Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the financial statements referred to above be included in Castelle's Annual Report on Forms 10-K and 10-K/A for the year ended December 31, 2001, filed with the Securities and Exchange Commission. Audit Committee of the Board of Directors ROBERT H. HAMBRECHT SCOTT C. MCDONALD JACK L. HOWARD 8 PROPOSAL NO. 2 ADOPTION OF 2002 EQUITY INCENTIVE PLAN You are being asked to vote on a proposal to approve the adoption of the 2002 Equity Incentive Plan, which we refer to as the 2002 Option Plan. The 2002 Option Plan was adopted by the Board of Directors on November 8, 2002, subject to shareholder approval and with such changes as may be required by the California Department of Corporations. The 2002 Option Plan will become effective upon its approval by our shareholders and the issuance of a permit by the California Department of Corporations. No grants have been made under the 2002 Option Plan. Castelle established the 2002 Option Plan as a successor to its 1988 Equity Incentive Plan, as adopted in 1998, and its 1995 Non-Employee Directors' Stock Option Plan, which we refer to collectively as the Prior Option Plan. The 2002 Option Plan was established to provide our employees, directors, consultants and independent advisors the opportunity to acquire shares of common stock through option grants, stock awards and other equity awards. Castelle's Board of Directors believes that options and other equity-based incentives have been important components of our success to date and that awards under the 2002 Option Plan will play an important role in our efforts to attract, employ and retain highly qualified employees, directors and consultants. The adoption of the 2002 Option Plan was necessitated by the use or expiration of all but an insignificant amount of authorized shares under the Prior Option Plan. We issue options to provide our employees an opportunity to acquire or increase their ownership stake in Castelle, creating a stronger incentive to expend maximum effort for our growth and success and encouraging our employees to continue their employment with us. If this proposal is approved by our shareholders, no additional option grants will be made under the Prior Option Plan. Options outstanding under the Prior Option Plan will remain outstanding until they are exercised or expire by their terms. As of October 24, 2002, options to purchase 1,565,577 shares were outstanding under the Prior Option Plan (at a weighted average exercise price per share of $1.01), 241,295 shares had been issued on exercise of options and 22,797 shares were available for future grant. Upon approval of the 2002 Option Plan, 850,000 shares will be available for future grant under the 2002 Option Plan. The principal terms and provisions of the 2002 Option Plan are summarized below. The summary is not intended to be a complete description of all the terms of the plan, and is qualified in its entirety by reference to the text of the 2002 Option Plan, which is attached hereto as Exhibit A. To the extent there is a conflict between this summary and the actual terms of the plan, the terms of the 2002 Option Plan will govern. Administration. The compensation committee of the Board (the "Committee"), or the Board acting as the Committee, will administer the 2002 Option Plan. The Committee will satisfy the requirements of the Securities and Exchange Commission in order to qualify awards under the 2002 Option Plan for the exemption under Rule 16b-3 (or its successor) under the Securities Exchange Act of 1934 and any other requirements specified under the tax laws to qualify awards under the 2002 Option Plan for the exemption under Section 162(m) of the Internal Revenue Code. The Committee has authority, subject to the express provisions of the 2002 Option Plan, to determine the individuals who are eligible to receive awards under the 2002 Option Plan, the number of shares to be covered by each option or other award, the date or dates on which the 9 option or award is to vest, the maximum term for which the option or award is to remain outstanding, whether an option will be an incentive stock option that satisfies the requirements of Section 422 of the Internal Revenue Code or a non-statutory option not intended to meet such requirements, and the other provisions of the award. Eligibility. Our employees, directors, consultants, independent contractors and advisors, and those of our subsidiaries are eligible to receive awards under the 2002 Option Plan. As of October 31, 2002, approximately 55 persons (including 9 officers and directors) were eligible to participate in the 2002 Option Plan. Securities Subject to 2002 Option Plan. If the 2002 Option Plan is approved by our shareholders, up to 850,000 shares of our common stock will initially be available for issuance under the plan. No one person participating in the 2002 Option Plan may receive options for more than 300,000 shares in any single year. Should an option under the 2002 Option Plan expire or terminate for any reason prior to being exercised in full, the shares subject to the unexercised portion of the option will be available for subsequent awards under the 2002 Option Plan. If restricted shares or shares issued upon exercise of options are forfeited and if stock units are forfeited or terminate before exercise, such shares will be available for subsequent awards under the 2002 Option Plan. If stock units are settled in shares, the number of shares available for future awards under the 2002 Option Plan will be reduced by only the actual number of shares of common stock actually issued in settlement. If an option under the Prior Option Plan expires or terminates for any reason, the shares subject to the option will not be available for awards under the 2002 Option Plan. Option Grant Program Price and Exercisability. The option exercise price per share in the case of an incentive stock option may not be less than 100% of the fair market value of the common stock on the grant date and, in the case of a non-statutory option, 85% of the fair market value of the common stock on the grant date. Options granted under the 2002 Option Plan become exercisable at such time or times as the Committee may determine and provide in the option grant agreement. The stock option agreement may provide for accelerated exercisability in the event of an optionee's death, disability or retirement or other events. The exercise price of a stock option may be paid in cash or in shares of common stock. Options may also be exercised through a same-day sale program or exercise and pledge program through a designated brokerage firm. No optionee will have any shareholder rights with respect to the shares issuable upon the exercise of options until the optionee has exercised the option, paid the exercise price and become a holder of record of the shares. During the optionee's lifetime, the option may be exercised only by the optionee and options are not assignable or transferable other than by will or the laws of descent and distribution. However, the Committee may allow an optionee to transfer options to members of the optionee's immediate family or to trusts or partnerships for the exclusive benefit of members of the optionee's immediate family. 10 Termination of Service. Any option held by the optionee upon termination of service will cease to be exercisable three months following termination of service, unless otherwise provided in such person's option agreement. Each such option will normally be exercisable only as to shares of common stock in which the optionee is vested at the time of termination. The Committee has complete discretion to extend the period following the optionee's termination during which his or her outstanding options may be exercised, and to accelerate the exercisability of such options in whole or in part. This discretion may be exercised at any time while the options remain outstanding. Incentive Stock Options. Incentive stock options may only be granted to individuals who are employees of Castelle or our subsidiaries. During any calendar year, the aggregate fair market value of the shares for which incentive stock options granted to any employee under the 2002 Option Plan (or any other Castelle option plan) first become exercisable will not exceed $100,000. Option Grants to Outside Directors. Outside directors of Castelle will receive automatic stock option grants under the 2002 Option Plan and will be eligible to receive discretionary grants. Outside directors are those who are not employees of Castelle or of any parent or subsidiary of Castelle and who are not representatives of any investor who owns 10% or more of the common stock. Options granted to outside directors under the 2002 Option Plan are not intended by Castelle to qualify as incentive stock options under the Code. Upon initial election to our Board of Directors, each person who is not an employee of Castelle is automatically granted an option to purchase shares of common stock. Under the terms of the 2002 Option Plan, on April 1 of each year (or the next business day should such date be a legal holiday), each outside director, without further action by Castelle, the Board, the Committee or our shareholders, will be automatically granted an option to purchase additional shares of common stock. These grants vest in 12 equal installments, beginning one month after the date of grant. The exercise price of options granted to outside directors under the 2002 Option Plan is 100% of the fair market value of the common stock subject to the option on the date of the option grant. The term of these options is ten years. Corporate Transactions. 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, the time during which outstanding options granted under the 2002 Option Plan are exercisable may be accelerated at the Board's discretion and the option may terminate prior to or within a prescribed period after the consummation of the transaction. The Committee may also provide in its sole discretion that the vesting of any options outstanding may become exercisable in full upon consummation of the transaction, and may terminate if not exercised prior to or within a prescribed time following consummation of the transaction. U.S. Federal Income Tax Information The following is a general summary of some of the current federal income tax consequences of the 2002 Option Plan to participants and to Castelle. Tax laws often change, and actual tax consequences depend on a participant's individual circumstances, as well as state and local tax laws. We encourage all participants to seek tax advice regarding their participation in the 2002 Option Plan. 11 Nonqualified Stock Options. Generally, a participant will not have taxable income when we grant him or her an nonqualified stock option (an "NQSO"). When a participant exercises a vested NQSO, the difference between the exercise price and the fair market value of our stock on the date of exercise (called the "spread") is taxable as ordinary income. Castelle withholds tax on this income when a participant who is a current or former employee exercises an NQSO. When the participant sells the shares, any additional gain or loss will be a capital gain or loss. Incentive Stock Options. As with NQSOs, an employee will generally not have taxable income when she or he receives an incentive stock option (an "ISO"). An employee will not have taxable income upon exercise of a vested ISO; however, the spread on exercise is alternative minimum taxable income to the participant in the year of exercise, unless she or he disposes of the shares in the same tax year. If the participant holds the shares for the ISO holding period, which is two years from the date of grant and one year from the date of exercise, the difference between the amount the participant paid for the shares on exercise and the sale price is capital gain or loss. If the participant disposes of the shares before the ISO holding period, the spread on exercise becomes taxable as ordinary income and the difference between the fair market value on the date of exercise and the price at which the participant sells the stock is capital gain or loss. Restricted Stock. A participant will generally be taxed on restricted stock when they receive stock or cash, unless there are restrictions on the shares that enable the participant to defer the tax. Tax Treatment of Castelle. When a participant recognizes ordinary income on exercise of an NQSO or on receipt of restricted stock, Castelle will generally be entitled to a deduction in the amount of the ordinary income recognized by the participant. Castelle will also be entitled to a deduction if the participant recognizes ordinary income by selling shares acquired on exercise of an ISO before the ISO holding period is met. Limitation on Number of Shares, and Required Vote to Approve Proposal No. 2 Pursuant to provisions contained in the California Corporate Securities Law applicable to corporations such Castelle, the number of shares of common stock issuable upon exercise of certain options and warrants issued or to be issued from time to time by Castelle, including without limitation, options issued or to be issued pursuant to the 2002 Option Plan, is limited to 30% of the sum of the (i) shares of common stock outstanding and (ii) shares of convertible preferred or convertible senior common, counted on an as if converted basis, that are outstanding at the time the calculation is made (the "30% Limit"). We may, however, issue options and warrants in excess of the 30% Limit if a percentage higher than 30% is approved by at least two-thirds of the outstanding shares entitled to vote. In calculating this 30% Limit, certain options and warrants are excluded in accordance with applicable provisions of California law. Options to be granted in the future pursuant to the 2002 Option Plan likely will be in excess of the 30% Limit. Accordingly, the affirmative vote of the holders of a two-thirds of the outstanding shares of common stock entitled to vote will be required to approve the 2002 Equity Incentive Plan and the issuance of all of the options authorized in the 2002 Equity Incentive Plan. Abstentions and broker non-votes will have the same effect as negative votes. THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 2. 12 PROPOSAL NO. 3 Amendment to Articles of Incorporation To Enable a Reverse Stock Split Background Castelle common stock is quoted on The NASDAQ Stock Market's SmallCap Market (the "SmallCap Market"). In order for the common stock to continue to be quoted on the SmallCap Market, Castelle must satisfy various listing maintenance standards established by NASDAQ. Among other things, Castelle is required to have a minimum bid price of at least $1.00 per share. Under current listing maintenance standards, if the closing bid price of shares of the common stock is under $1.00 per share for 30 consecutive trading days and does not thereafter reach $1.00 per share or higher for a minimum of ten consecutive trading days during the 180 calendar days following notification by NASDAQ, NASDAQ may delist the common stock from trading on the SmallCap Market. In that event, the common stock may trade on the OTC Bulletin Board maintained by the National Quotation Bureau, Inc. For reasons described below, this is generally considered to be less desirable than the SmallCap Market. In March 2002, we received a letter from NASDAQ advising us that Castelle common stock had not met NASDAQ's minimum bid price requirement for 30 consecutive trading days and that it would be delisted if we were unable to demonstrate compliance with this requirement for ten consecutive trading days during the 180 days ending September 9, 2002. On September 10, 2002, we received a letter from NASDAQ stating that our common stock had failed to meet the minimum bid price requirement, and that if we did not appeal the decision of the staff, then NASDAQ would delist our common stock. On September 16, 2002, we requested a hearing to appeal this decision. At a hearing on October 17, 2002, we presented our definitive plan to achieve compliance. Following the hearing, NASDAQ has indicated (but has not yet issued a written determination) that we would be permitted an extension to seek authorization for a reverse stock split to increase our minimum bid price above $1.00, to avoid delisting from the SmallCap Market. During the extension, any delisting would be held in abeyance. Consequently, the Board of Directors considered and has authorized, subject to shareholder approval, an amendment to the Articles of Incorporation to enable a reverse stock split for the purpose of increasing the market price of the common stock above the NASDAQ minimum bid requirement of $1.00. Under the proposed amendment, each outstanding 2 to 3 shares of common stock would be combined, converted and changed into one share of common stock with the Board to determine, after shareholder approval, which conversion ratio within this range will be used. The Board shall also have the authority, in its discretion, to abandon and not effect the reverse stock split following shareholder approval if the Board determines that the reverse stock split is no longer in the best interests of Castelle and its shareholders. Approval of the reverse stock split will authorize the Board in its discretion to effect the reverse stock split at a conversion ratio of between 1-for-2 and 1-for-3. The Board believes that shareholder approval of exchange ratios within a range (as opposed to approval of a specified conversion ratio) provides the Board with maximum flexibility to achieve the purposes of the reverse stock split and, therefore, is in the best interests of Castelle and its shareholders. If the reverse stock split is approved by the shareholders and following such approval the Board determines the reverse stock split is in the best interest of Castelle and its shareholders, 13 the Articles of Incorporation would be amended accordingly. The text of the form of amendment to the Articles of Incorporation, which would be filed with the Secretary of State of the State of California to effect the reverse stock split, is set forth in Exhibit B to this proxy statement; provided, however, that such text is subject to amendment to include the appropriate exchange ratio for the reverse stock split and such other changes as may be required by the office of the Secretary of State of the State of California and as the Board deems necessary or advisable to effect the reverse stock split. Reasons for the Reverse Stock Split The Board believes that a reverse stock split is desirable because it may allow Castelle to avoid having its common stock delisted from the SmallCap Market, and may improve the marketability and liquidity of our common stock. The reverse stock split is designed to increase the per share market price of the common stock. Our common stock is currently quoted on the SmallCap Market under the symbol "CSTL." During the period from January 1, 2002 to September 30, 2002, the closing sales price per share of our common stock ranged from a high of $1.05 to a low of $0.47. The closing sales price on October 24, 2002 was $1.02. The Board of Directors anticipates that a reverse stock split would have the effect of increasing trading prices of the common stock, which should result in a share price high enough to satisfy this NASDAQ listing requirement. The Board of Directors believes that the current low market price of the common stock has had a negative effect on the marketability of the existing shares. The Board believes there are several reasons for this effect. First, certain institutional investors have internal policies preventing the purchase of low-priced stocks. Additionally, a variety of policies and practices of broker-dealers discourage individual brokers within those firms from dealing in low-priced stocks. Second, because the brokers' commissions on low-priced stocks generally represent a higher percentage of the stock price than commissions on higher-priced stocks, the current share price of the common stock can result in individual shareholders paying transaction costs (commissions, markups or markdowns) which are a higher percentage of their total share value than would be the case if the share price of the common stock were substantially higher. This factor is also believed to limit the willingness of institutions to purchase the common stock. The Board believes that the anticipated increase in the price of the common stock as a result of the reverse stock split could encourage interest in the common stock. This might promote greater liquidity for shareholders, but a countervailing factor is that liquidity could be adversely affected by the reduced number of shares outstanding after the reverse stock split. It should be noted that if the reverse stock split is implemented, some shareholders may consequently own less than one hundred shares of common stock. A purchase or sale of less than one hundred shares (an "odd lot" transaction) may result in incrementally higher brokerage trading costs, particularly for "full service" brokers. Therefore, those shareholders who own less than one hundred shares following the reverse stock split incur higher transaction costs should they then determine to sell their shares in Castelle. Shareholders should note that the effect of the reverse stock split upon the market prices for our common stock cannot be accurately predicted. In particular, there is no assurance that prices for shares of the common stock after the reverse stock split will be two to three times higher than the prices for shares of the common stock immediately prior to the reverse stock split. Furthermore, there can be no assurance that the market price of the common stock immediately after the proposed reverse stock split will be maintained for any period of time. 14 Even if an increased share price can be maintained, the reverse stock split may not achieve the desired results which have been outlined above. Moreover, because some investors may view the reverse stock split negatively, there can be no assurance that the reverse stock split will not adversely impact the market price of the common stock or, alternatively, that the market price following the reverse stock split will either exceed or remain in excess of the current market price. Board Discretion to Implement Reverse Stock Split If it is approved by our shareholders at the Annual Meeting, the reverse stock split will be effected only upon a determination by the Board that the reverse stock split (with a conversion ratio determined by the Board) is in the best interests of Castelle and its shareholders. Such determination shall be based upon certain factors, including meeting the continued listing requirements for the SmallCap Market, existing and expected marketability and liquidity of the common stock, prevailing market conditions and the likely effect on the market price of the common stock. Notwithstanding approval of the reverse stock split by the shareholders, the Board may, in its sole discretion, abandon the proposed amendment and determine not to effect the reverse stock split, as permitted under applicable California law. If the Board does not implement a reverse stock split within the time frame authorized by shareholders, further shareholder approval would be required prior to implementing a reverse stock split thereafter. If the Board determines to effect the reverse stock split, it would be implemented as soon as reasonably practicable after shareholder approval. Effect of the Reverse Stock Split on Registration and Voting Rights The common stock is currently registered under Section 12(g) of the Securities Exchange Act of 1934, and we are subject to the periodic reporting and other requirements of the Exchange Act. The reverse stock split would not affect the registration of the common stock under the Exchange Act. After the reverse stock split, the common stock would continue to be listed on the SmallCap Market under the symbol "CSTL" (although NASDAQ would likely add the letter "D" to the end of the trading symbol for a period of 20 trading days to indicate that the reverse stock split has occurred). Proportionate voting rights and other rights of the holders of common stock would not be affected by the reverse stock split (other than as a result of the payment of cash in lieu of fractional shares as described below). For example, a holder of 2% of the voting power of the outstanding shares of common stock immediately prior to the effective time of the reverse stock split would continue to hold 2% of the voting power of the outstanding shares of common stock after the reverse stock split. Although the reverse stock split would not affect the rights of shareholders or any shareholder's proportionate equity interest in Castelle (subject to the treatment of fractional shares), the number of authorized shares of common stock would not be reduced and would increase significantly the ability of the Board to issue such authorized and unissued shares without further shareholder action. The number of shareholders of record would not be affected by the reverse stock split (except to the extent that any shareholder holds only a fractional share interest and receives cash for such interest after the reverse stock split). Effect of the Reverse Stock Split on the Authorized but Unissued Shares of Common Stock The number of authorized shares of common stock will not change as a result of the reverse stock split. Because the number of authorized and issued shares of common stock will be decreased by the reverse stock split, the number of authorized but unissued shares of common 15 stock will be increased significantly by the reverse stock split. As of October 24, 2002, there were 4,806,044 shares of common stock outstanding out of a total of 25,000,000 shares of common stock authorized under the Articles of Incorporation. The following table shows the aggregate number of authorized but unissued shares of common stock after a reverse split of the ratios being considered by this proposal: Common Stock Authorized and Reverse Split Ratio Outstanding (1) Unissued Common Stock (2) ------------------- --------------- ------------------------- current (no split) 4,806,044 20,193,956 1-for-2 2,403,022 22,596,978 1-for-3 1,602,014 23,397,986 (1) The figures in this table are calculated based 4,806,044 shares outstanding on October 24, 2002. These figures do not take into account any reduction in the number of outstanding shares of common stock resulting from the procedures for cashing out fractional shares, and do not include shares of common stock issuable upon exercise of outstanding options. (2) These figures are based on a pre-reverse stock split number of 25,000,000 authorized shares as of October 24, 2002. The future issuance of such additional authorized shares may have the effect of diluting the earnings per share and book value per share, as well as the stock ownership and voting rights, of the currently outstanding shares of common stock. The increase in the number of authorized but unissued shares of common stock may be construed as having an anti-takeover effect by permitting the issuance of shares to purchasers who might oppose a hostile takeover bid or oppose any efforts to amend or repeal certain provisions of the Articles of Incorporation or our Amended and Restated Bylaws. Effect of the Reverse Stock Split on Stock Options, Warrants and Par Value The reverse stock split would reduce the number of shares of common stock available for issuance under our 1988 Equity Incentive Plan and the 1995 Non-Employee Directors' Stock Option Plan in proportion to the conversion ratio of the reverse stock split. The number of shares of common stock currently authorized for issuance but unissued at October 24, 2002 under the 1988 Equity Incentive Plan and the Directors' Stock Option Plan is 21,797 and 1,000, respectively (prior to giving effect to the reverse stock split). Our common stock would continue to have no par value per share following the effective time of the reverse stock split, while the number of issued and outstanding shares of common stock would be reduced. Under the terms of Castelle's outstanding stock options, the reverse stock split will effect a reduction in the number of shares of common stock issuable upon exercise of such stock options in proportion to the exchange ratio of the reverse stock split and will effect a proportionate increase in the exercise price of such outstanding stock options. For example, after a 1-for-2 reverse stock split an original option grant to purchase 200 shares at $2.00 per share would become an option grant to purchase 100 shares at $4.00 per share. In connection with the reverse stock split, the number of shares of common stock issuable upon exercise or conversion of outstanding stock options will be rounded to the nearest whole share and no cash payment will be made in respect of such rounding. No fractional shares of common stock will be issued in connection with the proposed reverse stock split. Holders of common stock who would otherwise receive a fractional share of common stock pursuant to the reverse stock split will receive cash in lieu of the fractional share as explained more fully below. 16 Effective Date If the proposed reverse stock split is approved at the Annual Meeting and the Board of Directors elects to proceed with the reverse stock split in one of the approved conversion ratios, the reverse stock split would become effective as of 5:00 p.m. Pacific time on the date of filing of the applicable Certificate of Amendment to the Articles of Incorporation with the office of the Secretary of State of the State of California. Except as explained below with respect to fractional shares, on the effective date, shares of common stock issued and outstanding immediately prior thereto will, automatically and without any action on the part of the shareholders, be combined and converted into new shares of common stock in accordance with the reverse stock split conversion ratio determined by the Board within the limits set forth in this proposal. Exchange of Stock Certificates Shortly after the Effective Date, each holder of an outstanding certificate theretofore representing shares of common stock will receive instructions for the surrender of such certificate to ComputerShare Trust Company, Castelle's exchange agent (the "Exchange Agent") for the reverse stock split for the common stock. Such instructions will include a form of Transmittal Letter to be completed and returned to the Exchange Agent. As soon as practicable after the surrender to the Exchange Agent of any certificate that prior to the reverse stock split represented shares of common stock, together with a duly executed Transmittal Letter and any other documents the Exchange Agent may specify, the Exchange Agent shall deliver to the person in whose name such certificate had been issued certificates registered in the name of such person representing the number of full shares of common stock into which the shares of common stock previously represented by the surrendered certificate shall have been converted and a check for any amounts to be paid in cash in lieu of any fractional share. Each certificate representing shares of common stock issued in connection with the reverse stock split will continue to bear any legends restricting the transfer of such shares that were borne by the surrendered certificates representing the shares of common stock. Until surrendered as contemplated herein, each certificate that immediately prior to the reverse stock split represented any shares of common stock shall be deemed at and after the reverse stock split to represent the number of full shares of common stock as adjusted by the reverse stock split. No service charges, brokerage commissions or transfer taxes shall be payable by any holder of any certificate that prior to approval of the reverse stock split represented any shares of common stock, except that if any certificates of common stock are to be issued in a name other than that in which the certificates for shares of common stock surrendered are registered, it shall be a condition of such issuance that (i) the person requesting such issuance shall pay to Castelle any transfer taxes payable by reason thereof (or prior to transfer of such certificate, if any) or establish to our satisfaction that such taxes have been paid or are not payable, (ii) such transfer shall comply with all applicable federal and state securities laws and (iii) such surrendered certificate shall be properly endorsed and otherwise be in proper form for transfer. No Appraisal Rights Under California law, our shareholders would not be entitled to dissenters' or appraisal rights with respect to the reverse stock split. 17 Cash Payment in Lieu of Fractional Shares In lieu of any fractional shares to which a holder of common stock would otherwise be entitled as a result of the reverse stock split, we will pay cash equal to such fraction multiplied by the average of the high and low trading prices of the common stock on the SmallCap Market during regular trading hours for the five trading days immediately preceding the Effective Date. United States Federal Income Tax Consequences The following description of the material United States federal income tax consequences of the reverse stock split is based on the United States Internal Revenue Code of 1986, as amended (the "Code"), applicable Treasury Regulations promulgated thereunder, judicial authority and current administrative rulings and practices as in effect on the date of this Proxy Statement. Changes to the laws could alter the tax consequences described below, possibly with retroactive effect. We have not sought and will not seek an opinion of counsel or a ruling from the Internal Revenue Service regarding the United States federal income tax consequences of the reverse stock split. This discussion is for general information only and does not discuss the tax consequences which may apply to special classes of taxpayers (e.g., tax-exempt entities, non-resident aliens, mutual funds, regulated investment companies, broker/dealers or insurance companies). The state, local and foreign (non-United States) tax consequences of the reverse stock split may vary significantly as to each shareholder, depending upon the jurisdiction in which such shareholder resides. Shareholders are urged to consult their own tax advisors to determine the particular consequences to them. In general, the United States federal income tax consequences of the reverse stock split will vary among shareholders depending upon whether they receive cash for fractional shares or solely a reduced number of shares of common stock in exchange for their old shares of common stock. We believe that because the reverse stock split is not part of a plan to increase periodically a shareholder's proportionate interest in our assets or earnings and profits, the reverse stock split will likely have the following United States federal income tax effects: A shareholder who receives solely a reduced number of shares of common stock will not recognize gain or loss. In the aggregate, such a shareholder's basis in the reduced number of shares of common stock will equal the shareholder's basis in its old shares of common stock. A shareholder who receives cash in lieu of a fractional share as a result of the reverse stock split will generally be required to recognize a taxable gain or dividend income, depending on that shareholder's particular facts and circumstances. Generally, a shareholder receiving such a payment will recognize a taxable gain or dividend income in an amount equal to the lesser of (i) the amount of the cash payment received by the shareholder, or (ii) the excess of (A) the aggregate fair market value of the reduced number of shares of common stock received, plus the amount of the cash payment received, over (B) the shareholder's basis in all of the shareholder's old shares of common stock. In the aggregate, such a shareholder's basis in the reduced number of shares of common stock will equal the shareholder's basis in its old shares of common stock, and the holding period of the post-reverse stock split shares received will include the holding period of the pre-reverse stock split shares exchanged. Castelle will not recognize any gain or loss as a result of the reverse stock split. 18 Required Vote The affirmative vote of the holders of a majority of the outstanding shares of the common stock will be required to approve the reverse stock split and the amendment to the Articles of Incorporation to effect the reverse stock split. As a result, abstentions and broker non-votes will have the same effect as negative votes. THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 3. 19 PROPOSAL 4 RATIFICATION OF SELECTION OF INDEPENDENT AUDITORS The Board of Directors has selected PricewaterhouseCoopers LLP as our independent auditors for the fiscal year ending December 31, 2002 and has further directed that management submit the selection of independent auditors for ratification by the shareholders at the Annual Meeting. PricewaterhouseCoopers LLP has audited our financial statements since its 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. The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and voting at the Annual Meeting (which shares voting affirmatively also constitute at least a majority of the required quorum) will be required to ratify the selection of PricewaterhouseCoopers LLP. Abstentions and broker non-votes will not be counted for any purpose in determining whether any matter has been approved. Audit Fees. During the fiscal year ended December 31, 2001, the aggregate fees billed by PricewaterhouseCoopers LLP for the audit of our financial statements and for the review of our interim financial statements on Form 10-Q for such fiscal year was $118,806, of which an aggregate of $37,806 had been billed through December 31, 2001. Financial Information Systems Design and Implementation Fees. During the fiscal year ended December 31, 2001, there were no information consulting technology fees billed by PricewaterhouseCoopers LLP. All Other Fees. During fiscal year ended December 31, 2001, there were $15,000 in other professional service fees billed by PricewaterhouseCoopers LLP. The Audit Committee has determined that the rendering of certain other non-audit services by PricewaterhouseCoopers LLP is compatible with maintaining the auditor's independence. THE BOARD OF DIRECTORS RECOMMENDS A VOTE IN FAVOR OF PROPOSAL 4. 20 SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT The following table sets forth information regarding the ownership of Castelle's common stock as of October 24, 2002 by: (i) each director and nominee for director; (ii) each executive officer named in the Summary Compensation Table; (iii) all executive officers and directors of Castelle as a group; and (iv) all persons known by us to be beneficial owners of more than five percent of our common stock.

(1) This table is based upon information supplied by officers, directors and principal shareholders and Schedules 13D and 13G filed with the Securities and Exchange Commission (the "SEC"). Unless otherwise indicated in the footnotes to this table and subject to community property laws where applicable, Castelle believes 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 4,806,044 shares outstanding on October 24, 2002, the record date for this proxy, plus options exercisable within 60 days for the person being measured. (2) Based on correspondence from Mr. Howard dated November 12, 2002. Includes 439,560 shares held of record by WebFinancial Corporation. Mr. Howard is a director of WebFinancial Corporation. The table includes 10,832 shares of common stock subject to options beneficially held by Mr. Howard that were exercisable within 60 days of October 24, 2002. On November 12, 2002, Castelle repurchased all of the shares held by Mr. Howard. As part of that transaction, all of Mr. Howard's options were cancelled. In addition, Castelle repurchased all shares held by WebFinancial Corporation on November 12, 2002. Please refer to the section "Certain Relationships and Related Transactions". 21 (3) Includes 346,849 shares held by H&Q London Ventures, 60,835 shares held by H&Q Ventures IV, 1,250 shares held by Hamquist, 43,633 shares held by Hambrecht & Quist Venture Partners, and 129,059 shares held by Hambrecht & Quist California. Each of the entities named above and the entities' respective general partners, directors, executive officers, members and/or managers, as applicable, disclaim beneficial ownership of any securities other than those directly held by such person. (4) Includes shares subject to options exercisable within 60 days of October 24, 2002 as follows: 69,789 shares for Mr. Chen, 40,415 for Mr. Cheng, 29,999 for Mr. Hambrecht, 35,416 for Mr. McDonald, 88,749 for Mr. Petrovich, 500,000 for Mr. Rich and 29,999 for Mr. Tierney. Effective as of February 28, 2002, Mr. Elpiner was no longer employed by or affiliated with Castelle. (5) As a result of the transactions of November 12, 2002, described in "Certain Relationships and Related Transactions", Castelle repurchased all of the shares held by WebFinancial Corporation. (6) As a result of the repurchase described under "Certain Relationships and Related Transactions", as of November 12, 2002, the officers and directors as a group represented 8 persons and held 21.8% of the outstanding common stock. SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934 requires Castelle's directors and executive officers, and persons who own more than ten percent of the common stock, to file with the SEC initial reports of ownership and to file reports of changes in ownership of common stock. Officers, directors and greater than ten percent shareholders are required to furnish Castelle with copies of all Section 16(a) forms they file. To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, during the fiscal year ended December 31, 2001 all Section 16(a) filing requirements applicable to Castelle's officers, directors and greater than ten percent beneficial owners were complied with. 22 EXECUTIVE COMPENSATION COMPENSATION OF DIRECTORS Cash Compensation In 2001, the members of the Board of Directors received no cash compensation for their services as members of the Board, but were reimbursed for their expenses incurred in connection with attending Board meetings. Beginning in 2002, each non-employee director receives a quarterly retainer of $2,500 and a per meeting fee of $1,000 for each quarterly board meeting attended. Equity Compensation Each non-employee director receives stock option grants under the Directors' Plan. Options granted under the Directors' Plan are intended not to qualify as incentive stock options under the Code. The Directors' 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 24 equal installments, beginning one month after the date of grant provided that the optionee has continuously served as a non-employee 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 Directors' 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 Castelle, the Board or our shareholders. This annual grant to members of the Board under the Directors' 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 non-employee director. Prior to February 2002, the annual option grant was 10,000 shares to vest over 24 months. The exercise price of options granted under the Directors' 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 Directors' Plan is ten years. 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 Directors' Plan is accelerated and the option will terminate if not exercised prior to the consummation of the transaction. During fiscal 2001, we granted to each of Messrs. Hambrecht, Tierney and McDonald options to purchase 10,000 shares at exercise prices of $1.063 per share. 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). As of October 24, 2002, 11,249 had been exercised under the Directors' Plan. Upon approval of the 2002 Option Plan, non-employee directors will be eligible to receive automatic grants under the 2002 Option Plan on substantially the same terms as under the Directors' Plan. In addition, all directors will be eligible to receive discretionary grants. 23 Compensation of Executive Officers Summary of Compensation The following table shows for the fiscal years ended December 31, 2001, 2000 and 1999, compensation awarded or paid to, or earned by, our Chief Executive Officer and the four other most highly compensated executive officers at December 31, 2001 whose total annual salary and bonus exceeded $100,000 (the "Named Executive Officers"): SUMMARY COMPENSATION TABLE Long-Term Compensation Annual Compensation Awards Securities Name and Principal Fiscal Underlying - Position Year Salary Bonus ($)(1) Other($) Options (#) - -------- ---- ------ --------- -------- ----------- Donald L.

Also includes bonus amounts of $94,020 for Mr. Rich, $14,380 for Mr. Cheng, $11,259 for Mr. Chen and $10,949 for Mr. Elpiner for services rendered in fiscal 2000 but paid in fiscal 2001. (2) Mr. Cheng joined Castelle in March 2000. (3) Mr. Elpiner joined Castelle in April 1999 and left in February 2002. Stock Option Grants and Exercises Castelle grants options to its executive officers under its Prior Option Plan. As of December 31, 2001, options to purchase a total of 1,268,885 shares were outstanding under the Prior Option Plan and options to purchase 253,757 shares remained available for grant thereunder. Castelle did not grant any stock appreciation rights, restricted stock awards or stock purchase rights during 2001. 24 The following tables show for the fiscal year ended December 31, 2001, information regarding options granted to, exercised by, and held at year-end by the named executive officers: OPTION GRANTS IN LAST FISCAL YEAR Individual Grants Number of Percentage of Securities Total Options Potential Realizable Value at Underlying Granted to Assumed Annual Rates of Stock Options Employees in Exercise or Price Appreciation Name and Principal Granted (#) Fiscal Year Base Price Per Expiration for Option Term (4) Position (1) (%)(2) Share($)(3) Date 5% ($) 10% ($) - -------- --- ---------------- -------------- --------- ------ ------- Donald L.

(3) The exercise price is equal to 100% of the fair market value of common stock at the date of grant. (4) 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 10-year 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 Commission and do not represent our estimate or projection of future common stock prices. 25 AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES The following table sets forth the number of shares of common stock subject to exercisable and unexercisable stock options held as of December 31, 2001 by each of the named executive officers.

Mr. Rich resigned as Chief Executive Officer in April 2002. Mr. Rich's employment agreement provided for an annual base salary of $200,000, plus an annual bonus of up to a sum of $100,000, if certain performance criteria are met, or above $100,000 in the discretion of the Compensation Committee if performance criteria are exceeded. Performance criteria were evaluated quarterly, and performance bonuses earned and paid (to the extent earned) on a quarterly basis. Pursuant to his employment agreement, Mr. Rich was also granted an initial incentive stock award to purchase 300,000 shares of the common stock, one sixth of which vested after six months and the remainder vesting over the next thirty months. In November 1998, Castelle entered into a severance and transition benefit agreement with Mr. Rich pursuant to which we agreed that if we terminate Mr. Rich without cause or if Mr. Rich terminates his employment voluntarily for good cause, we are required to pay Mr. Rich 100% of his annualized salary and maintain the medical benefits conveyed to him for one year, and provide for the accelerated vesting of 100% of his outstanding options. The agreement allowed Mr. Rich to terminate his employment for good cause if his responsibilities were materially diminished, base pay was reduced, if Castelle failed to continue any benefit plan in which Mr. Rich was participating without comparable replacement, our corporate headquarters was relocated more than 20 miles from its current location or we breached this agreement or Mr. Rich's employment agreement. No payment would be due if Mr. Rich were dismissed for cause. The agreement also provided that Mr. Rich was eligible for a lump sum payment equal to six months of his base salary, in addition to any benefits conveyed to Mr. Rich upon termination, if he remained with Castelle at least 90 days after a change in control and his employment was subsequently terminated for any reason. 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 provides 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. Performance criteria will be evaluated quarterly, and performance bonuses will be earned and paid (to the extent earned) on a quarterly basis. The agreement also provides that during the first four quarters of his employment, Mr. McDonald will receive guaranteed bonus payments of $25,000 per quarter so long as he remains an employee in good standing. Mr. McDonald was 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. Castelle has 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 27 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, Castelle 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. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION The Compensation Committee currently consists of Robert H. Hambrecht and Peter R. Tierney, neither of whom has any interlocking relationships, as defined by the Securities and Exchange Commission except as described below. [The Remainder of this Page Intentionally Left Blank] 28 REPORT OF THE COMPENSATION COMMITTEE OF THE BOARD OF DIRECTORS ON EXECUTIVE COMPENSATION2 Our executive compensation program is administered by the Compensation Committee of the Board of Directors. The Committee currently consists of Robert Hambrecht and Peter Tierney, neither of whom is an employee of Castelle. 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, if approved, under the 2002 Option Plan. In determining executive officer compensation, the Compensation Committee considers corporate performance against Castelle's 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 Castelle's 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 Castelle. For 2001, Castelle's 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. Stock Options In addressing the first objective, the Compensation Committee utilizes stock option grants to executive officers to tie portion executive officer compensation directly to Castelle's stock price performance. The Compensation Committee believes that the grant of an equity interest in Castelle 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 Castelle and (iv) performance. In 2001, our executive officers received options to purchase common stock at levels ranging from 1,000 to 25,000 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; - ---------------------- 2 This Section is not "soliciting material," is not deemed "filed" with the SEC and is not to be incorporated by reference in any filing of Castelle under the 1933 Act or the 1934 Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing. 29 o Castelle's financial performance during the past year; and o each officer's performance against objectives related to their areas of responsibility. 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 our executive officers were not increased in 2001. The Compensation Committee believes that another key element of executive compensation should be the variable portion provided by cash incentive plans. The cash incentive portion of the executive officers' compensation is dependent primarily on our quarterly financial performance and achievement of specified corporate objectives as determined by the Compensation Committee. Castelle's executive officer compensation plan is designed such that if Castelle meets its stated objectives, executive officers receive the cash incentive part of their compensation. If Castelle performs below its 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 Board of Directors approves quarterly performance objectives for executives of Castelle. The actual cash bonus earned in 2001 by executive officers depended upon the extent to which Castelle's objectives were achieved. As a result of Castelle obtaining a certain percentage of such quarterly performance objectives, cash bonuses ranging from $30,002 to $72,717 were paid to executive officers for services performed during 2001. Castelle uses the same factors described above for the executive officers in setting the annual salary, stock option grant and cash incentives awarded to its Chief Executive Officer, formerly Donald Rich. The base salary of Mr. Rich included a mileage reimbursement of $2,600. Mr. Rich was eligible to earn a quarterly bonus of up to a maximum of $25,000, if Castelle achieved certain performance objectives outlined for Mr. Rich prior to the beginning of each quarter of 2001. As a result of Castelle obtaining a certain percentage of each quarterly financial target, Mr. Rich was awarded cash bonuses totaling $72,717 in 2001. Because of the amount of previous option grants to Mr. Rich, the Board did not award Mr. Rich any additional option grants during fiscal 2001. Section 162(m) Section 162(m) of the Internal Revenue Code, generally imposes an annual corporate deduction limitation of $1 million on the compensation of 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 30 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 Castelle. 2001 Compensation Committee ROBERT H.

In January 2001, we engaged W.R. Hambrecht + Co. ("WRH + Co."), an investment bank in which Mr. Hambrecht, one of our directors, is a partner, to provide certain financial advisory services. As of December 31, 2001, WRH + Co. had rendered an insignificant level of services to Castelle under this arrangement, and the agreement has now been terminated. Also, WRH + Co. has been selected to perform certain stock repurchase services for Castelle, as part of our common stock repurchase program announced on October 16, 2002. As of November 12, 2002, WRH + Co. had rendered an insignificant level of services to Castelle through these services. In November 2002, Castelle repurchased 1,600,000 shares of its common stock at a price of $1.10 per share in a private transaction. Of the 1,600,000 shares repurchased, 439,560 shares were repurchased from WebFinancial Corporation, which is a beneficial holder of more than 5% of the common stock, and 281,630 shares were repurchased from Jack L. Howard, who was a member of the Board of Directors of Castelle and a beneficial holder of more than 5% of the common stock. As part of the transaction, Mr. Howard agreed, pursuant to standstill provisions within the agreement, that for five years neither he nor any of his affiliates would: acquire any of Castelle's assets; purchase Castelle's shares; pursue a tender offer or exchange offer relating to Castelle; participate in any recapitalization, restructuring or extraordinary transaction with respect to Castelle; solicit any proxies or consents to vote any securities of Castelle; form or participate in a group with respect to the voting securities of Castelle; or nominate any person as a member of the Board of Directors of Castelle. WebFinancial Corporation and its affiliates agreed to similar restrictions for a period of one year. In addition, Castelle received proxies to vote all 1,600,000 of the repurchased shares, and Mr. Howard resigned from Castelle's Board of Directors. Our Bylaws provide that Castelle will indemnify directors and executive officers to the fullest extent permitted by California law. Under our Bylaws, indemnified parties are entitled to indemnification for negligence, gross negligence and otherwise to the fullest extent permitted by law. The Bylaws also require us to advance litigation expenses in the case of legal proceedings, against an undertaking by the indemnified party to repay such advances if it is ultimately determined that the indemnified party is not entitled to indemnification. 33 EQUITY COMPENSATION PLAN INFORMATION The following table sets forth certain information, as of December 31, 2001, concerning securities authorized for issuance under all equity compensation plans of Castelle: - ------------------------------- ---------------------------- ---------------------------- ---------------------------- Number of securities remaining available for Number of securities to be Weighted-average exercise future issuance under issued upon exercise of price of outstanding equity compensation plans Plan category outstanding options, options, warrants and (excluding securities warrants and rights rights reflected in column (a)) - ------------------------------- ---------------------------- ---------------------------- ---------------------------- (a) (b) (c) - ------------------------------- ---------------------------- ---------------------------- ---------------------------- Equity compensation plans approved by security holders 1,393,725 $1.08 274,797 (1) - ------------------------------- ---------------------------- ---------------------------- ---------------------------- Equity compensation plans not approved by security holders -- -- -- - ------------------------------- ---------------------------- ---------------------------- ---------------------------- Total 1,393,725 $1.08 274,797 - ------------------------------- ---------------------------- ---------------------------- ---------------------------- (1) Includes 21,797 shares available for issuance under our 1988 Equity Incentive Plan and 1,000 shares available for issuance under the Director's Plan.

(Reverse Side) Exhibit A CASTELLE 2002 EQUITY INCENTIVE PLAN As Adopted ____________, 2002 1. PURPOSE. The purpose of this Plan is to provide incentives to attract, retain and motivate eligible persons whose present and potential contributions are important to the success of the Company, its Parent and Subsidiaries, by offering them an opportunity to participate in the Company's future performance through awards of Options and Restricted Stock. Capitalized terms not defined in the text are defined in Section 23 ("Definitions). 2. SHARES SUBJECT TO THE PLAN. 2.1 Number of Shares Available. Subject to Sections 2.2 ("Adjustment of Shares") and 17 ("Corporate Transactions"), the total number of Shares reserved and available for grant and issuance pursuant to this Plan will be 850,000 Shares plus Shares that are subject to: (a) issuance upon exercise of an Option but cease to be subject to such Option for any reason other than exercise of such Option; (b) an Award granted hereunder but are forfeited or are repurchased by the Company at the original issue price; and (c) an Award that otherwise terminates without Shares being issued. 2.2 Adjustment of Shares. In the event that the number of outstanding shares of the Company's Common Stock is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company without consideration, then (a) the number of Shares reserved for issuance under this Plan, (b) the number of Shares that may be granted pursuant to Sections 3 ("Eligibility"), 5.10 ("No Disqualification") and 8 ("Automatic Grants to Outside Directors") below, (c) the Exercise Prices of and number of Shares subject to outstanding Options, and (d) the number of Shares subject to other outstanding Awards may, upon approval of the Board in its discretion, be proportionately adjusted in compliance with applicable securities laws; provided, however, that fractions of a Share will not be issued but will either be replaced by a cash payment equal to the Fair Market Value of such fraction of a Share or will be rounded up to the nearest whole Share, as determined by the Committee. 3. ELIGIBILITY. ISOs (as defined in Section 5 ("Options") below) may be granted only to employees (including officers and directors who are also employees) of the Company or of a Parent or Subsidiary of the Company. All other Awards may be granted to employees, officers, directors, consultants, independent contractors and advisors of the Company or any Parent or Subsidiary of the Company; provided such consultants, independent contractors and advisors render bona fide services not in connection with the offer and sale of securities in a capital-raising transaction. No person will be eligible to receive more than 300,000 Shares in any calendar year under this Plan pursuant to the grant of Awards hereunder. A person may be granted more than one Award under this Plan. EA-1 4. ADMINISTRATION. 4.1 Committee Authority. This Plan will be administered by the Committee or by the Board acting as the Committee. Except to the extent which may otherwise be required by the terms of Section 8 ("Automatic Grants to Outside Directors") hereof, and subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan. The Committee will have the authority to: (a) construe and interpret this Plan, any Award Agreement and any other agreement or document executed pursuant to this Plan; (b) prescribe, amend and rescind rules and regulations relating to this Plan or any Award; (c) select persons to receive Awards; (d) determine the form and terms of Awards; (e) determine the number of Shares or other consideration subject to Awards; (f) determine whether Awards will be granted singly, in combination with, in tandem with, in replacement of, or as alternatives to, other Awards under this Plan or any other incentive or compensation plan of the Company or any Parent or Subsidiary of the Company; (g) grant waivers of Plan or Award conditions; (h) determine the vesting, exercisability and payment of Awards; (i) correct any defect, supply any omission or reconcile any inconsistency in this Plan, any Award or any Award Agreement; (j) determine whether an Award has been earned; (k) initiate an Awards Exchange Program; and (l) make all other determinations necessary or advisable for the administration of this Plan. 4.2 Committee Discretion. Except for automatic grants to Outside Directors pursuant to Section 8 ("Automatic Grants to Outside Directors") hereof, any determination made by the Committee with respect to any Award will be made in its sole discretion at the time of grant of the Award or, unless in contravention of any express term of this Plan or the Award, at any later time, and such determination will be final and binding on the Company and on all persons having an interest in any Award under this Plan. The Committee may delegate to one or more officers of the Company the authority to grant an Award under this Plan to Participants who are not Insiders of the Company. EA-2 5. OPTIONS. The Committee may grant Options to eligible persons and will determine whether such Options will be Incentive Stock Options within the meaning of the Code ("ISOs") or Nonqualified Stock Options ("NQSOs"), the number of Shares subject to the Option, the Exercise Price of the Option, the period during which the Option may be exercised, and all other terms and conditions of the Option, subject to the following: 5.1 Form of Option Grant. Each Option granted under this Plan will be evidenced by an Award Agreement which will expressly identify the Option as an ISO or an NQSO ("Stock Option Agreement"), and, except to the extent which may otherwise be required by the terms of Section 8 ("Automatic Grants to Outside Directors") hereof, will be in such form and contain such provisions (which need not be the same for each Participant) as the Committee may from time to time approve, and which will comply with and be subject to the terms and conditions of this Plan. 5.2 Date of Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant such Option, unless otherwise specified by the Committee. The Stock Option Agreement and a copy of this Plan will be delivered to the Participant within a reasonable time after the granting of the Option. 5.3 Exercise Period. Options may be exercisable within the times or upon the events determined by the Committee as set forth in the Stock Option Agreement governing such Option; provided, however, that no Option will be exercisable after the expiration of ten (10) years from the date the Option is granted; and provided further that no ISO granted to a person who directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any Parent or Subsidiary of the Company ("Ten Percent Shareholder") will be exercisable after the expiration of five (5) years from the date the ISO is granted. The Committee also may provide for Options to become exercisable at one time or from time to time, periodically or otherwise, in such number of Shares or percentage of Shares as the Committee determines. 5.4 Exercise Price. The Exercise Price of an Option will be determined by the Committee when the Option is granted and may not be less than eighty-five percent (85%) of the Fair Market Value of the Shares on the date of grant; provided that: (i) the Exercise Price of an ISO will be not less than 100% of the Fair Market Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO granted to a Ten Percent Shareholder will not be less than 110% of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased may be made in accordance with Section7 ("Payment for Share Purchases"). 5.5 Method of Exercise. Options may be exercised only by delivery to the Company of a written stock option exercise agreement (the "Exercise Agreement") in a form approved by the Committee (which need not be the same for each Participant), stating the number of Shares being purchased, the restrictions imposed on the Shares purchased under such Exercise Agreement, if any, and such representations and agreements regarding the Participant's investment intent and access to information and other matters, if any, as may be required by or desirable to the Company to comply with applicable securities laws, together with payment in full of the Exercise Price for the number of Shares being purchased. EA-3 5.6 Termination. Notwithstanding the exercise periods set forth in the Stock Option Agreement, the exercise of an Option will always be subject to the following: (a) If the Participant is Terminated for any reason except the Participant's death or Disability, then the Participant may exercise such Participant's Options only to the extent that such Options would have been exercisable by the Participant on the Termination Date no later than three (3) months after the Termination Date (or such shorter or longer time period not exceeding five (5) years as may be determined by the Committee, with any exercise beyond three (3) months after the Termination Date deemed to be an NQSO), but in any event no later than the expiration date of the Options. (b) If the Participant is Terminated because of Participant's death or Disability (or the Participant dies within three (3) months after a Termination other than for Cause or because of the Participant's Disability), then the Participant's Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the Termination Date and must be exercised by the Participant (or the Participant's legal representative or authorized assignee) no later than twelve (12) months after the Termination Date (or such shorter or longer time period not exceeding five (5) years as may be determined by the Committee, with any exercise beyond (a) three (3) months after the Termination Date when the Termination is for any reason other than the Participant's death or Disability, or (b) twelve (12) months after the Termination Date when the Termination is for the Participant's death or Disability, deemed to be an NQSO), but in any event no later than the expiration date of the Options. (c) If the Participant is terminated for Cause, then Participant's Options shall expire on such Participant's Termination Date, or at such later time and on such conditions as are determined by the Committee. 5.7 Limitations on Exercise. The Committee may specify a reasonable minimum number of Shares that may be purchased on any exercise of an Option, provided that such minimum number will not prevent any Participant from exercising the Option for the full number of Shares for which it is then exercisable. 5.8 Limitations on ISOs. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to which ISOs are exercisable for the first time by a Participant during any calendar year (under this Plan or under any other incentive stock option plan of the Company or any Parent or Subsidiary of the Company) will not exceed $100,000. If the Fair Market Value of Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds $100,000, then the Options for the first $100,000 worth of Shares to become exercisable in such calendar year will be ISOs and the Options for the amount in excess of $100,000 that become exercisable in such calendar year will be NQSOs. In the event that the Code or the regulations promulgated thereunder are EA-4 amended after the Effective Date to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit will be automatically incorporated herein and will apply to any Options granted after the effective date of such amendment. 5.9 Modification, Extension or Renewal. The Committee may modify, extend or renew outstanding Options and authorize the grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant's rights under any Option previously granted. Any outstanding ISO that is modified, extended, renewed or otherwise altered will be treated in accordance with Section 424(h) of the Code. The Committee may reduce the Exercise Price of outstanding Options without the consent of Participants affected by a written notice to them; provided, however, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 5.4 ("Exercise Price") for Options granted on the date the action is taken to reduce the Exercise Price. 5.10 No Disqualification. Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent of the Participant affected, to disqualify any ISO under Section 422 of the Code. In no event shall the total number of Shares issued (counting each reissuance of a Share that was previously issued and then forfeited or repurchased by the Company as a separate issuance) under the Plan upon exercise of ISOs exceed 10,000,000 Shares (adjusted in proportion to any adjustments under Section 2.2 ("Adjustment of Shares") hereof) over the term of the Plan. 6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the Company to sell to an eligible person Shares that are subject to restrictions. The Committee will determine to whom an offer will be made, the number of Shares the person may purchase, the price to be paid (the "Purchase Price"), the restrictions to which the Shares will be subject, and all other terms and conditions of the Restricted Stock Award, subject to the following: 6.1 Form of Restricted Stock Award. All purchases under a Restricted Stock Award made pursuant to this Plan will be evidenced by an Award Agreement ("Restricted Stock Purchase Agreement") that will be in such form and contain such provisions (which need not be the same for each Participant) as the Committee may from time to time approve, and will comply with and be subject to the terms and conditions of this Plan. The offer of Restricted Stock Awards will be accepted by the Participant's execution and delivery of the Restricted Stock Purchase Agreement and full payment for the Shares to the Company within thirty (30) days from the date the Restricted Stock Purchase Agreement is delivered to the person. If such person does not execute and deliver the Restricted Stock Purchase Agreement along with full payment for the Shares to the Company within thirty (30) days, then the offer will terminate, unless otherwise determined by the Committee. 6.2 Purchase Price. The Purchase Price will be determined by the Committee on the date the Restricted Stock Award is granted or at the time the purchase is consummated, except in the case of a sale to a Ten Percent Shareholder, in which case the Purchase Price will be one hundred percent (100%) of the Fair Market Value on the date the Restricted Stock Award EA-5 is granted or at the time the purchase is consummated. Payment of the Purchase Price may be made in accordance with Section 7 ("Payment for Share Purchases"). 6.3 Terms of Restricted Stock Awards. Restricted Stock Awards shall be subject to such restrictions as the Committee may impose. These restrictions may be based upon completion of a specified number of years of service with the Company or upon completion of the performance goals as set out in advance in the Participant's individual Restricted Stock Purchase Agreement. Restricted Stock Awards may vary from Participant to Participant and between groups of Participants. Prior to the grant of a Restricted Stock Award, the Committee shall: (a) determine the nature, length and starting date of any Performance Period for the Restricted Stock Award; (b) select from among the Performance Factors to be used to measure performance goals, if any; and (c) determine the number of Shares that may be awarded to the Participant. Prior to the payment of any Restricted Stock Award, the Committee shall determine the extent to which such Restricted Stock Award has been earned. Performance Periods may overlap and Participants may participate simultaneously with respect to Restricted Stock Awards that are subject to different Performance Periods and having different performance goals and other criteria. 6.4 Termination During Performance Period. If a Participant is terminated during a Performance Period for any reason, then such Participant will be entitled to payment (whether in Shares, cash or otherwise) with respect to the Restricted Stock Award only to the extent earned as of the date of Termination in accordance with the Restricted Stock Purchase Agreement, unless the Committee determines otherwise. 7. PAYMENT FOR SHARE PURCHASES. 7.1 Payment. Payment for Shares purchased pursuant to this Plan may be made in cash (by check) or, where expressly approved for the Participant by the Committee and where permitted by law: (a) by cancellation of indebtedness of the Company to the Participant; (b) by surrender of shares that either: (1) have been owned by the Participant for more than six (6) months and have been paid for within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares); or (2) were obtained by the Participant in the public market; (c) by waiver of compensation due or accrued to the Participant for services rendered to the Company or a Parent or Subsidiary of the Company; (d) with respect only to purchases upon exercise of an Option, and provided that a public market for the Company's Common Stock exists: (1) through a "same day sale" commitment from the Participant and a broker-dealer that is a member of the National Association of Securities Dealers (an "NASD Dealer") whereby the Participant irrevocably elects to exercise the Option and to sell a portion of the EA-6 Shares so purchased to pay for the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to the Company; or (2) through a "margin" commitment from the Participant and an NASD Dealer whereby the Participant irrevocably elects to exercise the Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to the Company; or (e) by any combination of the foregoing. 7.2 Loan Guarantees. The Committee may, subject to its express approval and where permitted by law, help the Participant pay for Shares purchased under this Plan by authorizing a guarantee by the Company of a third-party loan to the Participant. 8. AUTOMATIC GRANTS TO OUTSIDE DIRECTORS. 8.1 Types of Options and Shares. Options granted under this Plan and subject to this Section 8 shall be NQSOs. 8.2 Eligibility. Options subject to this Section 8 shall be granted only to Outside Directors. 8.3 Initial Grant. Each Outside Director who first becomes a member of the Board on or after the Effective Date will automatically be granted an option for that fixed number of Shares which the Committee has established for initial grants to Outside Directors as of the date of each grant (an "Initial Grant") on the date such Outside Director first becomes a member of the Board, unless such Outside Director received a grant of options before the Effective Date. 8.4 Succeeding Grant. On April 1 of each year (or the next business day should such date be a legal holiday), each Outside Director will automatically be granted an option for that fixed number of Shares which the Committee has established for succeeding grants to Outside Directors as of the date of each grant (a "Succeeding Grant"), provided, that the Outside Director is a member of the Board on such date and has served continuously as a member of the Board for a period of at least twelve (12) months since the last option grant (whether an Initial Grant or a Succeeding Grant) to such Outside Director. If less than twelve (12) months has passed, then the number of shares subject to the Succeeding Grant will be pro-rated based on the number of days passed since the last option grant to such Outside Director, divided by 365 days. 8.5 Vesting. The date an Outside Director receives an Initial Grant or a Succeeding Grant is referred to in this Plan as the "Start Date" for such option. EA-7 (a) Initial Grant. Each Initial Grant will vest and be exercisable as to 8.33333% of the Shares at the end of each full succeeding month after the Start Date, so long as the Outside Director continuously remains a director or a consultant of the Company. (b) Succeeding Grant. Each Succeeding Grant will vest and be exercisable as to 8.33333% of the Shares at the end of each full succeeding month after the Start Date, so long as the Outside Director continuously remains a director or a consultant of the Company. 8.6 Exercise Price. The exercise price of an option pursuant to an Initial Grant or a Succeeding Grant shall be the Fair Market Value of the Shares at the time that such option is granted. 8.7 Termination. Except as provided below in this Section, the options granted under this Section 8 shall terminate and may not be exercised if the Outside Director ceases to be a member of the Board or a consultant of the Company. The date on which the Outside Director ceases to be a member of the Board or ceases to remain a consultant of the Company shall be referred to as the "Termination Date." (a) Termination Generally. If Outside Director ceases to be a member of the Board or a consultant of the Company for any reason except death, Disability or Cause, the options granted under this Section 8, to the extent (and only to the extent) that it would have been exercisable by such Outside Director on the Termination Date, may be exercised by the Outside Director within three (3) months after the Termination Date, but in no event later than the expiration date. (b) Death or Disability. If the Outside Director ceases to be a member of the Board or a consultant of the Company because of the death or Disability of the Outside Director, the options granted under this Section 8, to the extent (and only to the extent) that it would have been exercisable by the Outside Director on the Termination Date, may be exercised by the Outside Director within twelve (12) months after the Termination Date, but in no event later than the expiration date. (c) Cause. If the Outside Director is terminated for Cause, then the options granted under this Section 8 shall expire on such Outside Director's Termination Date, or at such later time and on such conditions as are determined by the Committee. 9. WITHHOLDING TAXES. 9.1 Withholding Generally. Whenever Shares are to be issued in satisfaction of Awards granted under this Plan, the Company may require the Participant to remit to the Company an amount sufficient to satisfy federal, state and local withholding tax requirements EA-8 prior to the delivery of any certificate or certificates for such Shares. Whenever, under this Plan, payments in satisfaction of Awards are to be made in cash, such payment will be net of an amount sufficient to satisfy federal, state, and local withholding tax requirements. 9.2 Stock Withholding. When, under applicable tax laws, a Participant incurs tax liability in connection with the exercise or vesting of any Award that is subject to tax withholding and the Participant is obligated to pay the Company the amount required to be withheld, the Committee may in its sole discretion allow the Participant to satisfy the minimum withholding tax obligation by electing to have the Company withhold from the Shares to be issued that number of Shares having a Fair Market Value equal to the minimum amount required to be withheld, determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose will be made in accordance with the requirements established by the Committee and be in writing in a form acceptable to the Committee. 10. TRANSFERABILITY. Awards granted under this Plan, and any interest therein, will not be transferable or assignable by Participant, other than by will or by the laws of descent and distribution, and may not be made subject to execution, attachment or similar process. During the lifetime of the Participant an Award will be exercisable only by the Participant or Participant's legal representative and any elections with respect to an Award may be made only by the Participant or Participant's legal representative. 11. PRIVILEGES OF STOCK OWNERSHIP; RESTRICTIONS ON SHARES. 11.1 Voting and Dividends. No Participant will have any of the rights of a shareholder with respect to any Shares until the Shares are issued to the Participant. After Shares are issued to the Participant, the Participant will be a shareholder and have all the rights of a shareholder with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares; provided, that if such Shares are restricted stock, then any new, additional or different securities the Participant may become entitled to receive with respect to such Shares by virtue of a stock dividend, stock split or any other change in the corporate or capital structure of the Company will be subject to the same restrictions as the restricted stock; provided, further, that the Participant will have no right to retain such stock dividends or stock distributions with respect to Shares that are repurchased at the Participant's Purchase Price or Exercise Price pursuant to Section 11.2 ("Restrictions on Shares"). 11.2 Restrictions on Shares. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s) in the Award Agreement a right to repurchase a portion of or all Unvested Shares held by a Participant following such Participant's Termination at any time within ninety (90) days after the later of the Participant's Termination Date and the date the Participant purchases Shares under this Plan, for cash and/or cancellation of purchase money indebtedness, at the Participant's Exercise Price or Purchase Price, as the case may be. 12. CERTIFICATES. All certificates for Shares or other securities delivered under this Plan will be subject to such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, EA-9 state or foreign securities law, or any rules, regulations and other requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed or quoted. 13. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a Participant's Shares, the Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee, appropriately endorsed in blank, with the Company or an agent designated by the Company to hold in escrow until such restrictions have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions to be placed on the certificates. Any Participant who is permitted to execute a promissory note as partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as collateral to secure the payment of the Participant's obligation to the Company under the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of such obligation and, in any event, the Company will have full recourse against the Participant under the promissory note notwithstanding any pledge of the Participant's Shares or other collateral. In connection with any pledge of the Shares, the Participant will be required to execute and deliver a written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note may be released from the pledge on a pro rata basis as the promissory note is paid. 14. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or from time to time, authorize the Company, with the consent of the respective Participants, to issue new Awards in exchange for the surrender and cancellation of any or all outstanding Awards, including but not limited to an exchange pursuant to an Award Exchange Program and including but not limited to an exchange for a new option at a lower exercise price, whether or not such exchange is simultaneous. The Committee may at any time buy from a Participant an Award previously granted with payment in cash, Shares (including restricted stock) or other consideration, based on such terms and conditions as the Committee and the Participant may agree. 15. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. This Plan is intended to comply with the California Corporations Code. Any provision of this Plan which is inconsistent with the California Corporations Code shall, without further act or amendment by the Company or the Board, be reformed to comply with the requirements of the California Corporations Code. An Award will not be effective unless such Award is in compliance with all applicable federal and state securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or quoted, as they are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates for Shares under this Plan prior to: (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and/or (b) compliance with any exemption, completion of any registration or other qualification of such Shares under any state or federal law or ruling of any governmental body that the Company determines to be necessary or advisable. The Company will be under no obligation to register the Shares with the SEC or to effect compliance with the exemption, registration, qualification or listing requirements of any state EA-10 securities laws, stock exchange or automated quotation system, and the Company will have no liability for any inability or failure to do so. 16. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted under this Plan will confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Parent or Subsidiary of the Company or limit in any way the right of the Company or any Parent or Subsidiary of the Company to terminate Participant's employment or other relationship at any time, with or without Cause. 17. CORPORATE TRANSACTIONS. 17.1 Assumption or Replacement of Awards by Successor. In the event of (a) a dissolution or liquidation of the Company, (b) a merger or consolidation in which the Company is not the surviving corporation (other than a merger or consolidation with a wholly-owned subsidiary, a reincorporation of the Company in a different jurisdiction, or other transaction in which there is no substantial change in the shareholders of the Company or their relative stock holdings and the Awards granted under this Plan are assumed, converted or replaced by the successor corporation, which assumption will be binding on all Participants), (c) a merger in which the Company is the surviving corporation but after which the shareholders of the Company immediately prior to such merger (other than any shareholder that merges, or which owns or controls another corporation that merges, with the Company in such merger) cease to own their shares or other equity interest in the Company, (d) the sale of substantially all of the assets of the Company, or (e) the acquisition, sale, or transfer of more than 50% of the outstanding shares of the Company by tender offer or similar transaction (each, a "Corporate Transaction"), any or all outstanding Awards may be assumed, converted or replaced by the successor corporation (if any), which assumption, conversion or replacement will be binding on all Participants. In the alternative, the successor corporation may substitute equivalent Awards or provide substantially similar consideration to Participants as was provided to shareholders (after taking into account the existing provisions of the Awards). The successor corporation may also issue, in place of outstanding Shares of the Company held by the Participants, substantially similar shares or other property subject to repurchase restrictions no less favorable to the Participant. In the event such successor corporation (if any) refuses to assume or substitute Awards, as provided above, pursuant to a transaction described in this Subsection 17.1, such Awards will expire on such transaction at such time and on such conditions as the Committee will determine. Notwithstanding anything in this Plan to the contrary, the Committee may, in its sole discretion, provide that the vesting of any or all Awards granted pursuant to this Plan will accelerate upon a transaction described in this Section 17. If the Committee exercises such discretion with respect to Options, such Options will become exercisable in full prior to the consummation of such event at such time and on such conditions as the Committee determines, and if such Options are not exercised prior to the consummation of the corporate transaction, they shall terminate at such time as determined by the Committee. 17.2 Other Treatment of Awards. Subject to any greater rights granted to Participants under the foregoing provisions of this Section 17, in the event of the occurrence of any Corporate Transaction described in Section 17.1, any outstanding Awards will be treated as EA-11 provided in the applicable agreement or plan of merger, consolidation, dissolution, liquidation, or sale of assets. 17.3 Assumption of Awards by the Company. The Company, from time to time, also may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition of such other company or otherwise, by either; (a) granting an Award under this Plan in substitution of such other company's award; or (b) assuming such award as if it had been granted under this Plan if the terms of such assumed award could be applied to an Award granted under this Plan. Such substitution or assumption will be permissible if the holder of the substituted or assumed award would have been eligible to be granted an Award under this Plan if the other company had applied the rules of this Plan to such grant. In the event the Company assumes an award granted by another company, the terms and conditions of such award will remain unchanged (except that the exercise price and the number and nature of Shares issuable upon exercise of any such option will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise Price. 18. ADOPTION AND SHAREHOLDER APPROVAL. This Plan will become effective on the date on which the registration statement filed by the Company with the SEC under the Securities Act registering the initial public offering of the Company's Common Stock is declared effective by the SEC (the "Effective Date"). This Plan shall be approved by the shareholders of the Company (excluding Shares issued pursuant to this Plan), consistent with applicable laws, within twelve (12) months before or after the date this Plan is adopted by the Board. Upon the Effective Date, the Committee may grant Awards pursuant to this Plan; provided, however, that: (a) no Option may be exercised prior to initial shareholder approval of this Plan; (b) no Option granted pursuant to an increase in the number of Shares subject to this Plan approved by the Board will be exercised prior to the time such increase has been approved by the shareholders of the Company; (c) in the event that initial shareholder approval is not obtained within the time period provided herein, all Awards granted hereunder shall be cancelled, any Shares issued pursuant to any Awards shall be cancelled, and any purchase of Shares issued hereunder shall be rescinded; and (d) in the event that shareholder approval of such increase shall not be obtained within the time period provided herein, all Awards granted pursuant to such increase shall be cancelled, any Shares issued pursuant to any Awards granted pursuant to such increase will be cancelled, and any purchase of Shares pursuant to such increase shall be rescinded. 19. TERM OF PLAN/GOVERNING LAW. Unless earlier Terminated as provided herein, this Plan will terminate ten (10) years from the date this Plan is adopted by the Board or, if earlier, the date of shareholder approval. This Plan and all agreements thereunder shall be governed by and construed in accordance with the laws of the State of California. 20. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate or amend this Plan in any respect, including, without limitation, amendment of any form of Award Agreement or instrument to be executed pursuant to this Plan; provided, however, that the Board will not, without the approval of the shareholders of the Company, amend this Plan in any manner that requires such shareholder approval pursuant to the EA-12 California Corporations Code, the Code or the regulations promulgated thereunder as such provisions apply to this Plan. 21. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the Board, the submission of this Plan to the shareholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases. 22. INSIDER TRADING POLICY. Each Participant and Outside Director who receives an Award shall comply with any policy adopted by the Company from time to time covering transactions in the Company's securities by employees, officers and/or directors of the Company. 23.

EA-16 Exhibit B CERTIFICATE OF AMENDMENT OF ARTICLES OF INCORPORATION OF CASTELLE The undersigned certify that: 1.

Article III of the Articles of Incorporation of this corporation is hereby amended and restated to read in its entirety as follows: "This corporation is authorized to issue two classes of stock to be designated, respectively, "Common Stock" and "Preferred Stock." The total number of shares which the corporation is authorized to issue is twenty-seven million (27,000,000) shares. Twenty-five million (25,000,000) shares will be Common Stock. Two million (2,000,000) shares shall be Preferred Stock. Effective upon the filing of this Certificate of Amendment, each [2 to 3] outstanding shares of Common Stock of the corporation will be combined into and automatically become one (1) outstanding share of Common Stock of the corporation. No fractional share shall be issued in connection with the foregoing reverse stock split; all shares of capital stock so combined that are held by a shareholder will be aggregated subsequent to the foregoing reverse stock split and each fractional share resulting from such aggregation held by a shareholder shall be paid in cash the value of such fractional shares. The Preferred Stock may be issued from time to time in one or more series. The Board of Directors is hereby authorized, to fix or alter the dividend rights, dividend rate, conversion rights, voting rights, rights and terms of redemption (including sinking fund provisions), redemption price or prices, and the liquidation preferences of any wholly unissued series of Preferred Stock, and the number of shares constituting any such series and the designation thereof, or any of them; and to increase or decrease the number of shares of any series subsequent to the issuance of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status that they had prior to the adoption of the resolution originally fixing the number of shares of such series." 3. The foregoing amendment of Articles of Incorporation has been duly approved by the board of directors. EB-1 4. The foregoing amendment of Articles of Incorporation has been duly approved by the required vote of shareholders in accordance with Section 902 of the California Corporations Code. The total number of outstanding shares of the corporation is 4,806,044 shares of Common Stock and no shares of Preferred Stock. The number of shares voting in favor of the amendment equaled or exceeded the vote required. The percentage vote required was more than 50% of the outstanding shares of Common Stock. We further declare under penalty of perjury under the laws of the State of California that the matters set forth in this certificate are true and correct of our own knowledge.
