Certain other capitalized terms used in this Agreement are defined in Exhibit B. RECITALS A. Castelle and Ibex intend to effect a merger of Ibex into Castelle in accordance with this Agreement and the California General Corporation Law ("CGCL") (the "Merger"). B. It is intended that the Merger qualify as a tax-free reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). For accounting purposes, it is intended that the Merger be treated as a "pooling of interests." C. This Agreement has been approved by the respective boards of directors of Castelle and Ibex. D. The Designated Shareholders own a total of 96,000 shares of the Common Stock (with no par value) of Ibex ("Ibex Common Stock"); and the Signing Shareholders own a total of 96,000 shares of Ibex Common Stock and a total of 48,035 shares of the Series A Convertible Preferred Stock of Ibex ("Series A Preferred Stock"), constituting all of the outstanding preferred stock of Ibex. Contemporaneously with the execution and delivery of this Agreement, each Signing Shareholder is executing and delivering to Castelle a Proxy of even date herewith. AGREEMENT The parties to this Agreement agree as follows: SECTION 1. DESCRIPTION OF TRANSACTION 1.1 Merger of Ibex into Castelle. Upon the terms and subject to the conditions set forth in this Agreement, at the Effective Time (as defined in Section 1.3), Ibex shall be merged with and into Castelle, and the separate existence of Ibex shall cease. Castelle will continue as the surviving corporation in the Merger (the "Surviving Corporation"). 11 1.2 Effect of the Merger. The Merger shall have the effects set forth in this Agreement and in the applicable provisions of the California General Corporation Law. 1.3 Closing; Effective Time. The consummation of the transactions contemplated by this Agreement (the "Closing") shall take place at the offices of Cooley Godward Castro Huddleson & Tatum, One Maritime Plaza, San Francisco, California 94111 at 10:00 a.m. on September __, 1996, or at such other time and date during the period from August 15, 1996 through December 30, 1996 as Castelle may designate upon not less than five days' prior notice to Ibex (the "Scheduled Closing Time"). (The date on which the Closing actually takes place is referred to in this Agreement as the "Closing Date.") Contemporaneously with or as promptly as practicable after the Closing, a properly executed agreement of merger conforming to the requirements of Chapter 11 of the California General Corporation Law shall be filed with the Secretary of State of the State of California. The Merger shall become effective at the time such agreement of merger is filed with and accepted by the Secretary of State of the State of California (the "Effective Time"). 1.4 Articles of Incorporation and Bylaws; Directors and Officers. Unless otherwise determined by Castelle prior to the Effective Time: (a) the Articles of Incorporation of the Surviving Corporation shall be those of Castelle; (b) the Bylaws of the Surviving Corporation shall be those of Castelle; and (c) the directors and officers of the Surviving Corporation immediately after the Effective Time shall be those of Castelle with the addition of Ney Grant as President of the Ibex Division of Castelle. 1.5 Conversion of Shares. (a) Subject to Sections 1.8(c) and 1.9, at the Effective Time, by virtue of the Merger and without any further action on the part of Castelle, Ibex or any shareholder of Ibex: (i) If the closing market price of a share of the common stock (no par value per share) of Castelle ("Castelle Common Stock") on the business day immediately prior to the Closing (the "Preference Price") is $9.42 or greater, each share of Ibex Common Stock and each share of Series A Preferred Stock outstanding immediately prior to the Effective Time shall be converted into the right to receive 4.171124044 shares of Castelle Common Stock. (ii) If the Preference Price is less than $9.42, (i) the aggregate shares of Series A Preferred Stock outstanding immediately prior to the Effective Time shall be converted into a number of shares of Castelle Common Stock equal to $180,000 divided by the Preference Price (the "Preferred Bonus Shares"), and (ii) each share of Ibex Common Stock and each share of Series A Preferred Stock outstanding immediately prior to the Effective Time shall be converted into a number of shares of Castelle Common Stock equal to (x) 850,000 less 12 the number of Preferred Bonus Shares divided by (y) the aggregate number of shares of Ibex Common Stock and Series A Preferred Stock outstanding, on a fully diluted basis, immediately prior to the Effective Time. (b) If any shares of Ibex Common Stock outstanding immediately prior to the Effective Time are unvested or are subject to a repurchase option, risk of forfeiture or other condition under any applicable restricted stock purchase agreement or other agreement with Ibex, then the shares of Castelle Common Stock issued in exchange for such shares of Ibex Common Stock will also be unvested and subject to the same repurchase option, risk of forfeiture or other condition, and the certificates representing such shares of Castelle Common Stock may accordingly be marked with appropriate legends. 1.6 Employee Stock Options. At the Effective Time, each stock option that is then outstanding under Ibex's 1992 Stock Option Plan, whether vested or unvested (a "Ibex Option"), shall be assumed by Castelle in accordance with the terms (as in effect as of the date of this Agreement) of Ibex's 1992 Stock Option Plan and the stock option agreement by which such Ibex Option is evidenced. All rights with respect to Ibex Common Stock under outstanding Ibex Options shall thereupon be converted into rights with respect to Castelle Common Stock. Accordingly, from and after the Effective Time, (a) each Ibex Option assumed by Castelle may be exercised solely for shares of Castelle Common Stock, (b) the number of shares of Castelle Common Stock subject to each such assumed Ibex Option shall be equal to the number of shares of Ibex Common Stock that were subject to such Ibex Option immediately prior to the Effective Time multiplied by the Applicable Fraction (as hereinafter defined), rounded down to the nearest whole number of shares of Castelle Common Stock, (c) the per share exercise price for the Castelle Common Stock issuable upon exercise of each such assumed Ibex Option shall be determined by dividing the exercise price per share of Ibex Common Stock subject to such Ibex Option, as in effect immediately prior to the Effective Time, by the Applicable Fraction (as hereinafter defined), and rounding the resulting exercise price up to the nearest whole cent, and (d) all restrictions on the exercise of each such assumed Ibex Option shall continue in full force and effect, and the term, exercisability, vesting schedule and other provisions of such Ibex Option shall otherwise remain unchanged; provided, however, that each such assumed Ibex Option shall, in accordance with its terms, be subject to further adjustment as appropriate to reflect any stock split, reverse stock split, stock dividend, recapitalization or other similar transaction effected by Castelle after the Effective Time. Ibex and Castelle shall take all action that may be necessary (under Ibex's 1992 Stock Option Plan and otherwise) to effectuate the provisions of this Section 1.6. Following the Closing, Castelle will send to each holder of an assumed Ibex Option a written notice setting forth (i) the number of shares of Castelle Common Stock subject to such assumed Ibex Option, and (ii) the exercise price per share of Castelle Common Stock issuable upon exercise of such assumed Ibex Option. For purposes of this Section 1.6, the "Applicable Fraction" shall mean the exchange ratio identified in Section 1.5 which is utilized to convert each share of Ibex Common Stock outstanding immediately prior to the Merger into Castelle Common Stock. 13 1.7 Closing of Ibex's Transfer Books. At the Effective Time, holders of certificates representing shares of Ibex's capital stock that were outstanding immediately prior to the Effective Time shall cease to have any rights as shareholders of Ibex, and the stock transfer books of Ibex shall be closed with respect to all shares of such capital stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Ibex's capital stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any of such shares of Ibex's capital stock (a "Ibex Stock Certificate") is presented to the Surviving Corporation, such Ibex Stock Certificate shall be canceled and shall be exchanged as provided in Section 1.8. 1.8 Exchange of Certificates. (a) At or as soon as practicable after the Effective Time, Castelle will send to the holders of Ibex Stock Certificates (i) a letter of transmittal in customary form and containing such provisions as Castelle may reasonably specify, and (ii) instructions for use in effecting the surrender of Ibex Stock Certificates in exchange for certificates representing Castelle Common Stock. Upon surrender of a Ibex Stock Certificate to Castelle for exchange, together with a duly executed letter of transmittal and such other documents as may be reasonably required by Castelle, the holder of such Ibex Stock Certificate shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of Castelle Common Stock that such holder has the right to receive pursuant to the provisions of this Section 1, and Ibex Stock Certificate so surrendered shall be canceled. Until surrendered as contemplated by this Section 1.8, each Ibex Stock Certificate shall be deemed, from and after the Effective Time, to represent only the right to receive upon such surrender a certificate representing shares of Castelle Common Stock (and cash in lieu of any fractional share of Castelle Common Stock) as contemplated by this Section 1.8. If any Ibex Stock Certificate shall have been lost, stolen or destroyed, Castelle may, in its discretion and as a condition precedent to the issuance of any certificate representing Castelle Common Stock, require the owner of such lost, stolen or destroyed Ibex Stock Certificate to provide an appropriate affidavit and to deliver a bond (in such sum as Castelle may reasonably direct) as indemnity against any claim that may be made against the Surviving Corporation with respect to such Ibex Stock Certificate. (b) No dividends or other distributions declared or made with respect to Castelle Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Ibex Stock Certificate with respect to the shares of Castelle Common Stock represented thereby, and no cash payment in lieu of any fractional share shall be paid to any such holder, until such holder surrenders such Ibex Stock Certificate in accordance with this Section 1.8 (at which time such holder shall be entitled to receive all such dividends and distributions and such cash payment). (c) No fractional shares of Castelle Common Stock shall be issued in connection with the Merger, and no certificates for any such fractional shares shall be issued. In lieu of such fractional shares, any holder of capital stock of Ibex who would otherwise be entitled to receive a fraction of a share of Castelle Common Stock (after aggregating all fractional shares of Castelle Common Stock issuable to such holder) shall, upon 14 surrender of such holder's Ibex Stock Certificate(s), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by the Designated Castelle Stock Price. For purposes of this paragraph, the "Designated Castelle Stock Price" shall be eight dollars ($8.00) per share of Castelle Common Stock. (d) The Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable to any holder or former holder of capital stock of Ibex pursuant to this Agreement such amounts as the Surviving Corporation may be required to deduct or withhold therefrom under the Code or under any provision of state, local or foreign tax law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid. (e) The Surviving Corporation shall not be liable to any holder or former holder of capital stock of Ibex for any shares of Castelle Common Stock (or dividends or distributions with respect thereto), or for any cash amounts, delivered to any public official pursuant to any applicable abandoned property, escheat or similar law. 1.9 Dissenting Shares. (a) Notwithstanding anything to the contrary contained in this Agreement, any shares of capital stock of Ibex that, as of the Effective Time, are or may become "dissenting shares" within the meaning of Section 1300(b) of the California Corporations Code shall not be converted into or represent the right to receive Castelle Common Stock in accordance with Section 1.5 (or cash in lieu of fractional shares in accordance with Section 1.8(c)), and the holder or holders of such shares shall be entitled only to such rights as may be granted to such holder or holders in Chapter 13 of the California General Corporation Law; provided, however, that if the status of any such shares as "dissenting shares" shall not be perfected, or if any such shares shall lose their status as "dissenting shares," then, as of the later of the Effective Time or the time of the failure to perfect such status or the loss of such status, such shares shall automatically be converted into and shall represent only the right to receive (upon the surrender of the certificate or certificates representing such shares) Castelle Common Stock in accordance with Section 1.5 (and cash in lieu of fractional shares in accordance with Section 1.8(c)). (b) Ibex shall give Castelle (i) prompt notice of any written demand received by Ibex prior to the Effective Time to require Ibex to purchase shares of capital stock of Ibex pursuant to Chapter 13 of the California General Corporation Law and of any other demand, notice or instrument delivered to Ibex prior to the Effective Time pursuant to the California General Corporation Law, and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. Ibex shall not make any payment or settlement offer prior to the Effective Time with respect to any such demand unless Castelle shall have consented in writing to such payment or settlement offer. 15 1.10 Tax Consequences. For federal income tax purposes, the Merger is intended to constitute a reorganization within the meaning of Section 368 of the Code. The parties to this Agreement hereby adopt this Agreement as a "plan of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Treasury Regulations. 1.11 Accounting Treatment. For accounting purposes, the Merger is intended to be treated as a "pooling of interests." 1.12 Further Action. If, at any time after the Effective Time, any further action is determined by Castelle to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession of and to all rights and property of Ibex, the officers and directors of the Surviving Corporation shall be fully authorized (in the name of Ibex and otherwise) to take such action.

(a) The representations and warranties made by the Designated Shareholders (including the representations and warranties set forth in Section 2 and the representations and warranties set forth in the Designated Shareholders' Closing Certificate) shall survive the Closing and shall expire on the first anniversary of the Closing Date; provided, however, that the representations and warranties as to all items expected to be encountered in the audit process shall terminate when Castelle publishes its audited financial statements for its fiscal year which includes the Closing Date, and further provided, however, that if, at any time prior to the termination of a specific representation or warranty, any Indemnitee (acting in good faith) delivers to Designated Shareholders a written notice alleging the existence of an inaccuracy in or a breach of such representation or warranty made by the Designated Shareholders (and setting forth in reasonable detail the basis for such Indemnitee's belief that such an inaccuracy or breach may exist) and asserting a claim for recovery under Section 9.2 based on such alleged inaccuracy or breach, then the claim asserted in such notice shall survive the termination of such specific representation or warranty until such time as such claim is fully and finally resolved. All representations and warranties made by Castelle shall terminate and expire as of the Effective Time, and any liability of Castelle with respect to such representations and warranties shall thereupon cease. (b) The representations, warranties, covenants and obligations of Ibex and the Designated Shareholders, and the rights and remedies that may be exercised by the Indemnitees, shall not be limited or otherwise affected by or as a result of any information furnished to, or any investigation made by or knowledge of, any of the Indemnitees or any of their Representatives. 55 (c) For purposes of this Agreement, each statement or other item of information set forth in the Disclosure Schedule or in any update to the Disclosure Schedule shall be deemed to be a representation and warranty made by Ibex and the Designated Shareholders in this Agreement. 9.2 Indemnification by Designated Shareholders. From and after the Effective Time (but subject to Section 9.1(a)), the Designated Shareholders, severally, to the extent of each such shareholder's pro rata interest in the Escrowed Shares, shall hold harmless and indemnify each of the Indemnitees from and against, and shall compensate and reimburse each of the Indemnitees for, any Damages which are directly or indirectly suffered or incurred by any of the Indemnitees or to which any of the Indemnitees may otherwise become subject (regardless of whether or not such Damages relate to any third-party claim) and which arise from or as a result of, or are directly or indirectly connected with: (i) any inaccuracy in or breach of any representation or warranty set forth in Section 2 or in the Designated Shareholders' Closing Certificate (without giving effect to any "Material Adverse Effect" or other materiality qualification or any similar qualification contained or incorporated directly or indirectly in such representation or warranty, but giving effect to any update to the Disclosure Schedule delivered by Ibex to Castelle prior to the Closing); (ii) any breach of any covenant or obligation of Ibex or any of the Designated Shareholders (including the covenants set forth in Sections 4 and 5); or (iii) any Legal Proceeding relating to any inaccuracy or breach of the type referred to in clause "(i)" or "(ii)" above (including any Legal Proceeding commenced by any Indemnitee for the purpose of enforcing any of its rights under this Section 9). 9.3 Threshold; Ceiling. The Designated Shareholders shall not be required to make any indemnification payment pursuant to Section 9.2(a) for any inaccuracy in or breach of any of their representations and warranties set forth in Section 2 until such time as the total amount of all Damages (including the Damages arising from such inaccuracy or breach and all other Damages arising from any other inaccuracies in or breaches of any representations or warranties) that have been directly or indirectly suffered or incurred by any one or more of the Indemnitees, or to which any one or more of the Indemnitees has or have otherwise become subject, exceeds $25,000 in the aggregate. (If the total amount of such Damages exceeds $25,000, then the Indemnitees shall be entitled to be indemnified against and compensated and reimbursed for the aggregate amount of Damages, including the initial $25,000.) 9.4 Escrow Fund. Notwithstanding Section 1.9 of this Agreement and in accordance with the provisions of the Escrow Agreement attached hereto as Exhibit L (the "Escrow Agreement), the Designated Shareholders shall deposit Castelle Common Stock equal to ten percent (10%) of the shares of Castelle Common Stock to be received by the Ibex shareholders as a result of the transactions contemplated by the Agreement (the "Escrowed Shares") with the Escrow Agent to be held pursuant to the terms of the Escrow Agreement for a period of one year from the date of the Closing. Upon compliance with the terms 56 of Section 9 of this Agreement and the Escrow Agreement, and subject to Section 9.3 above, the Indemnitees shall be entitled to obtain indemnity from the Escrow Fund for Damages covered by Section 9. 9.5 No Contribution. Each Designated Shareholder waives, and acknowledges and agrees that he shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against the Surviving Corporation in connection with any indemnification obligation or any other liability to which he may become subject under or in connection with this Agreement or the Designated Shareholders' Closing Certificate. 9.6 Interest. Any Designated Shareholder who is required to hold harmless, indemnify, compensate or reimburse any Indemnitee pursuant to this Section 9 with respect to any Damages shall also be liable to such Indemnitee for interest on the amount of such Damages (for the period commencing as of the date on which such Designated Shareholder first received notice of a claim for recovery by such Indemnitee and ending on the date on which the liability of such Designated Shareholder to such Indemnitee is fully satisfied by such Designated Shareholder) at a floating rate equal to the rate of interest publicly announced by Bank of America, N.T. & S.A. from time to time as its prime, base or reference rate. 9.7 Defense of Third Party Claims. In the event of the assertion or commencement by any Person of any claim or Legal Proceeding (whether against Castelle or against any other Person) with respect to which any of the Designated Shareholders may become obligated to hold harmless, indemnify, compensate or reimburse any Indemnitee pursuant to this Section 9, Castelle shall have the right, at its election, to proceed with the defense of such claim or Legal Proceeding on its own. If Castelle so proceeds with the defense of any such claim or Legal Proceeding: (a) all reasonable expenses relating to the defense of such claim or Legal Proceeding shall be borne and paid exclusively by the Designated Shareholders; (b) each Designated Shareholder shall make available to Castelle any documents and materials in his possession or control that may be necessary to the defense of such claim or Legal Proceeding; and (c) Castelle shall have the right to settle, adjust or compromise such claim or Legal Proceeding with the consent of the Designated Shareholders' Agent (as defined in Section 10.1); provided, however, that such consent shall not be unreasonably withheld. Castelle shall give the Designated Shareholders' Agent prompt notice of the commencement of any such Legal Proceeding against Castelle; provided, however, that any failure on the part of Castelle to so notify the Designated Shareholders' Agent shall not limit any of the obligations of the Designed Shareholders under this Section 9 (except to the extent such failure materially prejudices the defense of such Legal Proceeding). 57 9.8 Exercise of Remedies by Indemnitees Other Than Castelle. No Indemnitee (other than Castelle or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement unless Castelle (or any successor thereto or assign thereof) shall have consented to the assertion of such indemnification claim or the exercise of such other remedy. Such consent shall be evidenced by the submission by Castelle of such claim to the Designated Shareholders' Representative. 9.9 Claims Against Consideration. Upon delivery to the Designated Shareholders' Agent (with a copy to Escrow Agent, as such term is defined in the form of Escrow Agreement attached hereto as Exhibit L) of a certificate signed by any officer of Castelle (an "Officer's Certificate"): (a) stating that an Indemnitee has paid or properly accrued or reasonably anticipates that it will have to pay or accrue Damages in an aggregate stated amount to which an Indemnitee is entitled to indemnity pursuant to this Agreement (the "Claim Amount"); and (b) specifying in reasonable detail the individual items of Damages included in the amount so stated, the date each such item was paid or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty, legal proceeding or claim to which such item is related, the Indemnitee shall be entitled to indemnification for such Damages. (c) Castelle and the Indemnitees shall use reasonable efforts to provide such Officer's Certificate within a reasonable time following the date of payment, accrual or reasonable anticipation of liability, as the case may be. 9.10 Objections to Claims. For a period of twenty (20) business days after delivery of any Officer's Certificate to the Designated Shareholders' Agent, the Indemnitees shall not take further actions to seek indemnification. After the expiration of such twenty (20 business day period, the Indemnitees shall become irrevocably entitled to seek indemnification under the terms of this Agreement, if the Designated Shareholders' Agent shall not have objected in writing to the claim made in the Officer's Certificate, and shall not have delivered such written objection to Castelle prior to the expiration of such ten day period. 9.11 Resolution of Conflicts; Arbitration (a) In case the Designated Shareholders' Agent so objects in writing to the indemnity of the Indemnitees in respect of any claim or claims made in any Officer's Certificate, the Designated Shareholders' Agent and the Indemnitees shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims. If the Designated Shareholders' Agent and the Indemnitees so agree, a memorandum setting forth such agreement shall be prepared and signed by the Indemnitees and the Designated Shareholders' Agent, which agreement shall be binding and conclusive on the Indemnitees and the Designated Shareholders (a "Response Notice"). 58 (b) If no such agreement can be reached after good faith negotiation, either the Indemnitees or the Designated Shareholders' Agent may demand arbitration of the matter by serving a written demand for arbitration on the other (the "Demand for Arbitration"); provided, however, that if the amount of the Damages is at issue in pending litigation with a third party, arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration. The decision of the arbitrator so selected as to the validity and amount of any claim in such Officer's Certificate shall be binding and conclusive upon the Indemnitees and the Designated Shareholders. (c) Any such arbitration shall be held in San Francisco, California before the single arbitrator under the commercial arbitration rules then in effect of the American Arbitration Association ("AAA"), except as modified herein. (i) Selection. The single arbitrator shall have at least five years of experience in commercial dispute resolution. The arbitrator shall be selected by mutual agreement between the Indemnitees and the Designated Shareholders' Agent, but if they cannot agree upon the selection within ten days after Demand for Arbitration is given, the selection shall occur as follows: (a) the party initiating arbitration shall obtain a list of seven arbitrators, each of whom shall have the requisite experience described above, from the San Francisco office of the AAA and simultaneously give a copy thereof to the other party; (b) each party alternately shall strike three names from the list, with the other party striking first; and (c) the last remaining arbitrator shall be deemed selected by the parties as a single arbitrator. If a party refuses for ten or more days to complete this selection, the other party shall select a name from the list to be the arbitrator at the end of such ten day period. (ii) Procedure. Arbitration shall be conducted in the following manner: (a) If the responding party desires to file a response and/or counterclaim to the Demand for Arbitration, it must do so within ten calendar days after service of the Demand for Arbitration. Any response to a counterclaim shall be filed and served within ten calendar days after service of the counterclaim, but no such response shall be required. A failure to file a counterclaim or response will not operate to delay the arbitration proceedings. (b) After the filing of the Demand for Arbitration, any counterclaim and any responses thereto, no further claims or counterclaims may be made except by order of the arbitrator made on a duly noticed motion to the arbitrator. (c) The arbitration shall commence as soon as possible but in no event earlier than ten days after selection of the arbitrator and in no event later than 30 days following the filing of the last response under (b) above, or if there is none, following the Demand for Arbitration. 59 (d) the Indemnitees and the Designated Shareholders' Representative (acting on behalf of the Designated Shareholders and being entitled to reimbursement under Section 10.1) shall each pay an equal share of the fees and expenses of any person serving as an arbitrator. The arbitrator, in his or her discretion, shall be authorized to determine whether a party is the prevailing party, and if so, to award that prevailing party reimbursement for its share of the costs and fees of the arbitrator, and reimbursement for its reasonable attorneys' fees, disbursements and costs incurred in such arbitration. (e) The arbitrator, upon application of any party, shall hold a pre-hearing conference with the parties for the purpose of narrowing the issues, establishing a discovery schedule, arranging an acceptable procedure for any law and motion proceedings and in all respects arranging for the most expeditious hearing possible of the matters in dispute. Such conference shall be held as soon as possible following selection of the arbitrator, any counterclaim thereto and any response to such counterclaim (if any), but in no event later than 20 days following the filing of the last response under (b) above, or if there is none, following the Demand for Arbitration. (f) Discovery shall be conducted in accordance with Part 3, Title 9, Chapter 3 of the California Code of Civil Procedure, as amended from time to time. (g) Except as expressly provided in this Section 9.11.3, the arbitration hearing shall be conducted according to the discretion of the arbitrator. Judicial rules relating to the order of proof, the conduct of the hearing and the presentation and admissibility of evidence need not be followed. Any relevant information, including hearsay, may be admitted by the arbitrator regardless of its admissibility as evidence in court, but the arbitrator also shall be authorized to exclude evidence. The parties shall have the power to subpoena witnesses to attend the arbitration hearing pursuant to California Code of Civil Procedure Section 1282.6. The arbitrator shall have full power to give such directions and to make such orders in the conduct of the arbitration, including setting pre-arbitration procedures and scheduling any motions to correct or amend the arbitration award, as he or she deems just and appropriate, including specifically the right to make such reasonable extensions of time as the arbitrator determines are necessary to accommodate discovery, prearbitration procedures, motions, settlement discussions, and other such matters, but not in any event to exceed 30 days in the aggregate, from the date the arbitration was otherwise scheduled to commence as provided above. (h) The arbitrator shall, within five days after the conclusion of the arbitration hearing, issue a written decision and a brief written statement of decision describing the reasons for the decision, including the calculation of any compensatory damages awarded. (i) Absent the filing of an application to correct or vacate the arbitration award as provided in section (j) below, each party shall fully perform and satisfy the terms of the arbitration decision within 15 days of the service of the decision. 60 (j) The decision of the arbitrator shall be final and binding upon the parties without appeal or review except as permitted by California law; provided, however, that either party may, within ten days of the service of the decision, file an application to correct or vacate the arbitration award or an application for de novo review on all questions of law based on the arbitrator's finding of fact (which are deemed for such purpose to be stipulated by the parties), in either case under California Code of Civil Procedure Section 1285 et seq. Any party may apply to any court of competent jurisdiction for confirmation and entry of judgment based on said award. In connection with any application to review questions of law or to confirm, correct or vacate the arbitration award, any appeal of any order rendered pursuant to any such application, or any other action required to enforce the arbitration award, the prevailing party shall be entitled to recover its reasonable attorneys' fees, disbursements and costs incurred in such post-award activities. (d) The arbitrator shall not have the power to vary the provisions of this Agreement. The parties hereby irrevocably waive, and the arbitrator shall have no power to award, any damages for pain and suffering or punitive damages. (e) By signing below, each party acknowledges that (a) the arbitration provisions of this Agreement require the party to give up rights to have the dispute litigated in a court or jury trial, and to give up rights to discovery and most grounds for appeal, and (b) the party may be compelled to arbitrate if the party refuses to do so. SECTION 10. MISCELLANEOUS PROVISIONS 10.1 Designated Shareholders' Agent. The Designated Shareholders hereby irrevocably appoint Ney Grant as their agent for purposes of Section 9 (the "Designated Shareholders' Agent"), and Ney Grant hereby accepts his appointment as the Designated Shareholders' Agent. Castelle shall be entitled to deal exclusively with the Designated Shareholders' Agent on all matters relating to Section 9, and shall be entitled to rely conclusively (without further evidence of any kind whatsoever) on any document executed or purported to be executed on behalf of any Designated Shareholder by the Designated Shareholders' Agent, and on any other action taken or purported to be taken on behalf of any Designated Shareholder by the Designated Shareholders' Agent, as fully binding upon such Designated Shareholder.

Any such successor shall become the "Designated Shareholders' Agent" for purposes of Section 9 and this Section 10.1. The Designated Shareholders' Agent shall receive no compensation for his services, but shall be reimbursed for his reasonable out-of-pocket expenses by the Designated Shareholders in proportion to the number of shares of Castelle Common Stock received by each of them pursuant to this Agreement. If for any reason there is no Designated Shareholders' Agent at any time, all references herein to the Designated Shareholders' Agent shall be deemed to refer to the Designated Shareholders. 61 10.2 Further Assurances.

RECITALS A. The Affiliates are shareholders of IBEX TECHNOLOGIES, INC., a California corporation (the "Company"). B. Castelle, the Company, the Affiliates and certain other shareholders of the Company have entered into an Agreement and Plan of Reorganization dated as of August 22, 1996 (the "Reorganization Agreement") providing for the merger of the Company with and into Castelle (the "Merger"). The Reorganization Agreement contemplates that, upon consummation of the Merger, all outstanding shares of capital stock of the Company will be converted into the right to receive shares of common stock of Castelle ("Castelle Common Stock"). It is accordingly contemplated that the Affiliates will receive shares of Castelle Common Stock in the Merger. C. Each Affiliate may be deemed to be an "affiliate" of the Company for purposes of (i) the restrictions on resale imposed by interpretations of the staff of the Securities and Exchange Commission (the "SEC") in transactions exempted from registration under the Securities Act of 1933, as amended (the "Securities Act"), and (ii) determining Castelle's eligibility to account for the Merger as a "pooling of interests" under Accounting Series Releases 130 and 135, as amended, of the SEC. AGREEMENT 1. Representations and Warranties. The Affiliates severally represent and warrant to Castelle as follows: (a) Each Affiliate is the holder and beneficial owner of the number of shares of the Company's capital stock set forth under Affiliate's signature below (the "Shares"), and Affiliate has good and valid title to the Shares, free and clear of any liens, pledges, security interests, adverse claims, equities, options, proxies, charges, encumbrances or restrictions of any nature. (b) Each Affiliate has carefully read this Agreement, and has discussed with counsel to the extent Affiliate felt necessary the limitations imposed on Affiliate's ability to sell, transfer or otherwise dispose of the Shares, the shares of Castelle Common Stock that Affiliate is to receive in the Merger (the "Castelle Shares") and other shares of the capital stock of the Company or Castelle. Affiliate fully understands the limitations this 75 Agreement places upon Affiliate's ability to sell, transfer or otherwise dispose of the Shares, and the Castelle Shares and other shares of capital stock of the Company or Castelle. (c) Each Affiliate understands that the representations, warranties and covenants set forth herein will be relied upon by Castelle and its counsel and accountants for purposes of determining Castelle's eligibility to account for the Merger as a "pooling of interests," for purposes of determining whether to proceed with the Merger and for other purposes. 2. Prohibition Against Transfer. Each Affiliate agrees that: (a) until such time as the Reorganization Agreement is validly terminated in accordance with its terms, such Affiliate shall not sell, transfer or otherwise dispose of, or reduce Affiliate's interest in or risk relating to, (i) any capital stock of the Company (including the Shares and any additional shares of capital stock of the Company acquired by Affiliate, whether upon exercise of a stock option or otherwise), or (ii) any option to purchase any capital stock of the Company, except pursuant to and upon consummation of the Merger; (b) during the period from the date on which the Merger is consummated through the date on which financial results covering at least 30 days of post-Merger combined operations of Castelle and the Company have been published by Castelle (within the meaning of the applicable "pooling of interests" accounting requirements), Affiliate shall not sell, transfer or otherwise dispose of, or reduce Affiliate's interest in or risk relating to, (i) any shares of Castelle Common Stock (including the Castelle Shares) and any additional shares of Castelle Common Stock acquired by Affiliate, whether upon exercise of a stock option or otherwise, or (ii) any option to purchase shares of Castelle Common Stock; and (c) without limiting the generality of the foregoing, or the effect of clause (b) of this Section 2, Affiliate shall not effect any sale, transfer or other disposition of the Castelle Shares unless: (i) such sale, transfer or other disposition is made in conformity with the volume and other requirements of Rule 145(d) under the Securities Act, as evidenced by a broker's letter and a representation letter executed by Affiliate, each stating that such requirements have been met; (ii) counsel reasonably satisfactory to Castelle shall have advised Castelle in a written opinion letter upon which Castelle may rely that such sale, transfer or other disposition will be exempt from registration under the Securities Act; (iii) such sale, transfer or other disposition has been registered under the Securities Act; or (iv) an authorized representative of the SEC shall have rendered written advice to Affiliate to the effect that the SEC would take no 76 action, or that the staff of the SEC would not recommend that the SEC take action, with respect to such proposed sale, transfer or other disposition, and a copy of such written advice and all other related communications with the SEC shall have been delivered to Castelle. For purposes of Section 2(c)(ii), counsel reasonably satisfactory to Castelle shall include, in the case of sales, transfers or other dispositions by Tucha Limited, Newark Holding S.A. and Teodoro Ramos Gimenez, the law firm of Morse, Barnes-Brown & Pendleton, P.C., presently in Waltham, Massachusetts. 3. Stop Transfer Instructions. (a) Each Affiliate acknowledges and agrees that stop transfer instructions will be given to Castelle's transfer agent with respect to the Castelle Shares and with respect to any shares of Castelle Common Stock acquired by Affiliate upon any exercise of any option to purchase shares of Castelle Common Stock, and that there will be placed on the certificates representing such shares of Castelle Common Stock or any substitutions thereof a legend, stating in substance: THE SHARES REPRESENTED BY THIS CERTIFICATE ARE RESTRICTED AND MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AS OF AUGUST __, 1996, BETWEEN THE REGISTERED HOLDER HEREOF AND CASTELLE, A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF CASTELLE." (b) Castelle agrees that such stop transfer instructions and legends will be removed with respect to shares of Castelle Common Stock at such time as Castelle is reasonably satisfied that the restrictions on resale imposed by interpretations of the staff of the Commission are no longer applicable to such shares. 4. Specific Performance. Affiliate agrees that irreparable damages would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms, or were otherwise breached.

("Ibex") and the Signing Shareholders Ladies and Gentlemen: This letter is supplied to you in connection with your rendering of opinions regarding certain United States federal income tax consequences of the Merger. Unless otherwise indicated, capitalized terms not defined herein have the meanings set forth in the Agreement. Representations The undersigned officer of Ibex, a California corporation, on behalf of the management of Ibex, after consulting with legal counsel and financial auditors regarding the meaning of and factual support for the following representations, hereby represents, in connection with the proposed merger of Ibex, a California corporation, with and into Castelle in a statutory merger (the "Merger") pursuant to the Agreement and Exhibits thereto including but not limited to the Agreement of Merger, that as of the time this letter is executed, the following facts are true and will continue to be true as of the Effective Time and Closing of the Merger and thereafter where relevant: 1. Ibex's principal reasons for participating in the Merger are bona fide business reasons. 2. The total fair market value of all consideration other than Castelle voting common stock received by Ibex shareholders in exchange for their Ibex common and preferred stock in the Merger (including, without limitation, cash paid to Ibex shareholders perfecting dissenters' rights and cash paid in lieu of fractional shares) will be less than ten percent (10%) of the aggregate fair market value of Ibex common and preferred stock outstanding immediately prior to the Merger. 3. The liabilities of Ibex assumed by Castelle and the liabilities to which the transferred assets of Ibex are subject were incurred by Ibex in the ordinary course of its business. 83 4. The fair market value of Ibex's assets on the Effective Date which are transferred to Castelle will exceed the aggregate liabilities of Ibex plus the amount of liabilities, if any, to which such assets are subject, and the total adjusted basis of the assets of Ibex transferred to Castelle will equal or exceed the sum of the liabilities assumed by Castelle, plus the amount of liabilities, if any, to which the transferred assets are subject. 5. Ibex is not and will not be on the Effective Date an "investment company" within the meaning of ss. 368(a)(2)(F) of the Internal Revenue Code of 1986, as amended, (the "Code"). 6. Ibex has no knowledge of any plan or intention on the part of any Ibex shareholder (a "Plan") to engage in a sale, exchange, transfer, distribution, pledge, disposition or any other transaction which would result in a direct or indirect disposition (a "Sale") of shares of Castelle voting common stock to be issued to Ibex shareholders in the Merger, which shares would have an aggregate fair market value, as of the Effective Date of the Merger, in excess of fifty-percent (50%) of the aggregate fair market value, immediately prior to the Merger, of all outstanding shares of Ibex common and preferred stock. For purposes of this representation, shares of Ibex common and preferred stock (or the portion thereof) (i) with respect to which a Ibex shareholder receives consideration in the Merger other than Castelle voting common stock (including, without limitation, cash received pursuant to the exercise of dissenters' rights or paid in lieu of issuing fractional shares) and/or (ii) with respect to which a sale occurs during the Pre-Merger Period, shall be considered shares of outstanding Ibex common and preferred stock exchanged for Castelle voting common stock in the Merger and then disposed of pursuant to a Plan. 7. The payment of cash by Castelle in lieu issuing fractional shares of Castelle voting common stock is solely for the purpose of avoiding the expense and inconvenience to Castelle of issuing fractional shares and does not represent separately bargained for consideration. The Castelle fractional share interests to which each Ibex shareholder may be entitled in the Merger will be aggregated so that no Ibex shareholder will receive cash in an amount which would equal or exceed, in the aggregate, the value of one whole share of Castelle voting common stock. 8. Except with respect to (1) payments of cash to Ibex shareholders perfecting dissenters' rights, and (2) payments of cash in lieu of fractional shares of Castelle voting common and preferred stock, one hundred percent (100%) of the Ibex common and preferred stock outstanding immediately prior to the 84 Merger will be exchanged solely for Castelle voting common stock. Thus, except as set forth in the preceding sentence, Ibex intends that no consideration be paid or received (directly or indirectly, actually or constructively) for Ibex common and preferred stock other than Castelle voting common stock. 9. During the Pre-Merger Period, no indebtedness or other obligation of Ibex has been or will be guaranteed by any shareholder of Ibex (or any person or entity related to a shareholder of Ibex). 10. On the Effective Date of the Merger, the fair market value of the Castelle voting common stock and other consideration received by each Ibex shareholder will be approximately equal to the aggregate fair market value of the Ibex common and preferred stock surrendered in exchange therefor. 11. Ibex and the shareholders of Ibex will each pay separately its or their own expenses in connection with the Merger as contemplated by the Agreement; provided, however, that to the extent any expenses relating to the Merger (or the "plan of reorganization" within the meaning of Treas. Reg. ss. 1.368-1(c) with respect to the Merger) are funded directly or indirectly by a party other than the incurring party, such expenses will be within the guidelines established in Rev. Rul. 73-54, 1973-1 C.B. 187. 12. There is no intercorporate indebtedness existing between Castelle and Ibex that was issued, acquired, or will be settled at a discount, and to the best knowledge of the management of Ibex, Castelle will assume no liabilities of any Ibex shareholder in connection with the Merger. 13. The terms of the Agreement and all other agreements entered into pursuant thereto are the product of arm's length negotiations. 14. None of the compensation payments received by any shareholder of Ibex will be separate consideration for, or allocable to, any of their shares of Ibex common or preferred stock. None of the shares of Castelle voting common stock received by any shareholder of Ibex will be separate consideration for, or allocable to, any employment agreement, consulting agreement, any covenants not to compete or otherwise for the performance of services; and the compensation paid to any shareholder of Ibex will be for services actually rendered and will be commensurate with amounts paid to third parties bargaining at arm's length for similar services. 15. Ibex is authorized to make all of the representations set forth herein. 85 GENERAL YOUR RELIANCE IN RENDERING OPINIONS LIMITATIONS ON YOUR OPINIONS 1. The undersigned recognize that (i) your opinions will be based on, among other things, the representations and statements set forth herein, in the Agreement (including exhibits attached thereto), and in the documents related thereto, and (ii) your opinions will be subject to certain limitations, qualifications and assumptions including that the opinions may not be relied upon if any such representations or statements are not accurate in all material respects. 2.

Castelle's principal reasons for participating in the Merger are bona fide business reasons. 2. Castelle has no plan or intention to reacquire any of its stock issued in the Merger. 3. Castelle has no plan or intention to sell or otherwise dispose of any of the assets of Ibex acquired in the Merger, except for dispositions made in the 87 ordinary course of business or transfers described in section 368(a)(2)(C) of the Internal Revenue Code of 1986, as amended (the "Code"). 4. Following the Merger, Castelle will continue Ibex's historic trade or business or use a significant portion of its historic business assets in a business. 5. Castelle is not, and will not be on the Effective Date, an "investment company" within the meaning of section 368(a)(2)(F) of the Code. 6. No shareholder of Ibex is acting as agent for Castelle in connection with the Merger or approval thereof, and Castelle will not reimburse any Ibex shareholder for Ibex common stock or preferred stock such shareholder may have purchased or for other obligations such shareholder may have incurred. 7. The payment of cash by Castelle in lieu of issuing fractional shares of Castelle voting common stock is solely for the purpose of avoiding the expense and inconvenience to Castelle of issuing fractional shares and does not represent separately bargained for consideration. The Castelle fractional share interests to which each Ibex shareholder may be entitled in the Merger will be aggregated so that no Ibex shareholder will receive cash in an amount which would equal or exceed, in the aggregate, the value of one whole share of Castelle voting common stock. 8. Except with respect to (1) payments of cash to Ibex shareholders perfecting dissenters' or appraisal rights and (2) payments of cash in lieu of fractional shares of Castelle voting common stock or preferred stock, one hundred percent (100%) of the Ibex common stock and preferred stock outstanding immediately prior to the Merger will be exchanged solely for Castelle voting common stock. Thus, except as set forth in the preceding sentence, Castelle intends that no consideration be paid or received (directly or indirectly, actually or constructively) for Ibex common stock or preferred stock other than Castelle voting common stock. 9. The total fair market value of all consideration other than Castelle voting common stock received by Ibex shareholders in exchange for their Ibex common stock or preferred stock in the Merger (including, without limitation, cash paid to Ibex shareholders perfecting dissenters' or appraisal rights and cash paid in lieu of fractional shares) will be less than ten percent (10%) of the aggregate fair market value of Ibex common stock and preferred stock outstanding immediately prior to the Merger. In addition, the total cash 88 consideration that will be paid in the Merger to Ibex shareholders in lieu of fractional shares of Castelle voting common stock will not exceed one percent (1%) of the total consideration that will be issued in the Merger to the Ibex shareholders in exchange for their shares of Ibex common stock and preferred stock. 10. On the Effective Date of the Merger, the fair market value of the Castelle voting common stock and other consideration received by each Ibex shareholder will be approximately equal to the aggregate fair market value of the Ibex common stock and preferred stock surrendered in exchange therefor. 11. Castelle will pay separately its own expenses in connection with the Merger as contemplated by the Agreement; provided, however, that to the extent any expenses relating to the Merger (or the "plan of reorganization" within the meaning of Treas. Reg. ss. 1.368-1(c) with respect to the Merger) are funded directly or indirectly by a party other than the incurring party, such expenses will be within the guidelines established in Rev. Rul. 73-54, 1973-1 C.B. 187. 12. There is no intercorporate indebtedness existing between Castelle and Ibex that was issued, acquired, or will be settled at a discount, and Castelle will not assume any liabilities of Ibex's shareholders in connection with the Merger. 13. The terms of the Agreement and all other agreements entered into pursuant thereto are the product of arm's-length negotiations. 14. None of the compensation payments which might be received by any shareholder of Ibex will be separate consideration for, or allocable to, any of their shares of Ibex common stock or preferred stock; none of the shares of Castelle voting common stock to be received by any shareholder of Ibex will be separate consideration for, or allocable to, any employment agreement, consulting agreement, any covenants not to compete or otherwise for the performance of services; and the compensation which might be paid to any shareholder of Ibex will be for services actually rendered and will be commensurate with amounts paid to third parties bargaining at arm's length for similar services. 15.

(b) To the extent any opinion is rendered herein with respect to the enforceability of any agreement: (1) we express no opinion as to the effect on such enforceability of applicable federal or state bankruptcy, insolvency, reorganization, moratorium or other similar laws generally affecting relief of debtors or the enforcement of the rights of creditors; (2) we express no opinion as to the effect on such enforceability of laws governing specific performance, injunctive relief, fraudulent sales and/or conveyances, preferences or other equitable remedies; (3) the enforceability of obligations in the Agreements is subject to general principles of equity regardless of whether such enforceability is considered in a proceeding in equity or law, and a court applying such principles may refuse to enforce, or may limit the application of, a contract or any clause thereof; and (4) enforcement of indemnification provisions contained in the Agreements may be limited by applicable law. (c) We express no opinion herein as to compliance or non-compliance with federal or state securities laws, including but not limited to, the antifraud provisions of any state or federal securities law, rule or regulation. (d) We have acted as counsel to the Company and the Signing Shareholders only with respect to certain corporate matters, the negotiation of the Agreements and the rendering of these opinions. Accordingly, we may not have knowledge of all matters of fact or law relating to the Company or the Signing Shareholders that may be relevant in connection with the opinions herein. Any alteration of those facts may adversely affect our opinions. Whenever a statement herein is qualified by "known to us," "to our current actual knowledge," or similar phrase, it is intended to indicate that during the course of our representation of the Company, no information that would give us current actual knowledge of the inaccuracy of such statement has come to the attention of those attorneys in this firm who have rendered legal services to the Company. However, except as otherwise expressly indicated, we have not undertaken any independent investigation to determine the accuracy of any such statement (including, without limitation, any search of litigation filings in any court), and any limited inquiry undertaken by us during the preparation of this letter should not be regarded as such an investigation. No inference as to our current actual knowledge of any matters bearing on the accuracy of any such statement should be drawn from the fact of our representation of the Company. 113 Castelle ______________, 1996 (e) With regard to our opinion in paragraph 4 below, we have examined and relied upon a certificate executed by an officer of the Company, to the effect that the consideration for all outstanding shares of capital stock of the Company was received by the Company in accordance with the provisions of the applicable Board of Directors resolutions and any plan or agreement relating to the issuance of such shares, and we have undertaken no independent verification with respect thereto. (f) With regard to our opinion in paragraph 5 below with respect to material defaults under any material agreement known to us, we have relied solely upon (i) inquiries of officers of the Company, (ii) a list supplied to us by the Company, a copy of which has been supplied to your counsel, Cooley Godward Castro Huddleson & Tatum, of material agreements to which the Company is a party, or by which it is bound, and (iii) an examination of the items on the aforementioned list; we have made no further investigation. On the basis of the foregoing, in reliance thereon and with the foregoing qualifications, we are of the opinion that: 1. The Company has been duly incorporated and is a validly existing corporation in good standing under the laws of the State of California. 2. The Company has the requisite corporate power to own or lease its property and assets and to conduct its business as it is currently being conducted and, to the best of our knowledge, is qualified as a foreign corporation to do business and is in good standing in each jurisdiction in the United States in which the ownership of its property or the conduct of its business requires such qualification and where any statutory fines or penalties or any corporate disability imposed for the failure to qualify would materially and adversely affect the Company, its assets, financial condition or operations. 3. The Agreements have been duly and validly authorized, executed and delivered by the Company and constitute valid and binding agreements of the Company and the Signing Shareholders enforceable against the Company and the respective Signing Shareholders in accordance with their terms. 4. The Company's authorized capital stock consists of (a) ten million (10,000,000) shares of Common Stock, without par value, of which one hundred forty-one thousand sixteen (141,016) shares are issued and outstanding, and (b) five million (5,000,000) shares of Preferred Stock, without par value, of which forty-eight thousand thirty-five (48,035) shares have been designated Series A Preferred Stock, without par value, of which all such shares are issued and outstanding. The outstanding shares of Common Stock and of Preferred Stock have been authorized and validly issued 114 Castelle ______________, 1996 and are fully paid and nonassessable. The rights, preferences and privileges of the Series A Preferred Stock are as stated in the Certificate of Determination of Preferences of Series A Preferred Stock. To the best of our knowledge, there are no options, warrants, conversion privileges, preemptive rights or other rights presently outstanding to purchase any of the authorized but unissued capital stock of the Company, other than the conversion privileges of the Series A Preferred Stock, rights created in connection with the transactions contemplated by the Agreements and twenty thousand (20,000) shares reserved for issuance under the Company's 1992 Stock Option Plan, of which fourteen thousand seven hundred thirty-one (14,731) shares are subject to outstanding options. 5. The execution and delivery of the Agreements by the Company do not violate any provision of the Company's Articles of Incorporation or Bylaws, and do not constitute a material default under the provisions of any material agreement known to us to which the Company is a party or by which it is bound, and do not violate or contravene (a) any governmental statute, rule or regulation applicable to the Company or (b) any order, writ, judgment, injunction, decree, determination or award which has been entered against the Company and of which we are aware, the violation or contravention of which would materially and adversely affect the Company, its assets, financial condition or operations. 6. To the best of our knowledge, there is no action, proceeding or investigation pending or overtly threatened against the Company before any court or administrative agency that questions the validity of the Agreements or might result, either individually or in the aggregate, in any material adverse change in the assets, financial condition, or operations of the Company. 7. All consents, approvals, authorizations, or orders of, and filings, registrations, and qualifications with any regulatory authority or governmental body in the United States required for the consummation by the Company and, to our knowledge, the Signing Shareholders, of the transactions contemplated by the Agreements, have been made or obtained. 115 Castelle ______________, 1996 This opinion is intended solely for your use in connection with the transactions contemplated by the Agreements and is not to be made available to or relied upon by other persons or entities without our prior written consent. Our opinion is expressly limited to the matters set forth above and we render no opinion, whether by implication or otherwise, as to any other matters relating to the Company or the Signing Shareholders.

("Ibex") with and into the Company pursuant to an Agreement and Plan of Reorganization dated as of August 22, 1996 (the "Reorganization Agreement") by and among the Company, Ibex and the Signing Shareholders listed on Exhibit A-1 and A-2 of the Reorganization Agreement (the "Merger) and the issuance and sale of [eight hundred fifty thousand (850,000)] shares of Castelle Common Stock (the "Shares") in connection with the Merger. We are rendering this opinion pursuant to Section 6.6(i) of the Reorganization Agreement. Except as otherwise defined herein, capitalized terms used but not defined herein have the respective meanings given to them in the Reorganization Agreement. In connection with this opinion, we have examined and relied upon the representations and warranties as to factual matters contained in and made pursuant to the Reorganization Agreement by the various parties and originals or copies certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinion expressed below. Where we render an opinion "to the best of our knowledge" or concerning an item "known to us" or our opinion otherwise refers to our knowledge, it is based solely upon (i) an inquiry of attorneys within this firm who perform legal services for the Company, (ii) receipt of a certificate executed by an officer of the Company covering such matters, and (iii) such other investigation, if any, that we specifically set forth herein. In rendering this opinion, we have assumed: the genuineness and authenticity of all signatures on original documents; the authenticity of all documents submitted to us as originals; the conformity to originals of all documents submitted to us as copies; the accuracy, completeness and authenticity of certificates of public officials; and the due authorization, execution and delivery of all documents (except the due authorization, execution and delivery by the Company of the Reorganization Agreement and the exhibits thereto, including the Merger Agreement and the Disclosure Schedule, (collectively the "Agreements"), where authorization, execution and delivery are prerequisites to the effectiveness of such documents. We have also assumed: that all individuals executing and delivering documents had the legal capacity to so execute and deliver; that you have received all documents you were to receive under the Agreements; that the Agreements are obligations binding upon you; if you are a corporation or other entity, that you have filed any required California 118 franchise or income tax returns and have paid any required California franchise or income taxes; and that there are no extrinsic agreements or understandings among the parties to the Agreements that would modify or interpret the terms of the Agreements or the respective rights or obligations of the parties thereunder. Our opinion is expressed only with respect to the federal laws of the United States of America and the laws of the State of California. We express no opinion as to whether the laws of any particular jurisdiction apply, and no opinion to the extent that the laws of any jurisdiction other than those identified above are applicable to the subject matter hereof. We are not rendering any opinion as to compliance with any antifraud law, rule or regulation. With regard to our opinion in paragraph 4 below with respect to material defaults under any material agreement known to us, we have relied solely upon (i) inquiries of officers of the Company, (ii) a list supplied to us by the Company, a copy of which has been supplied to your counsel, Graham & James LLP, of material agreements to which the Company is a party, or by which it is bound, and (iii) an examination of the items on the aforementioned list; we have made no further investigation. On the basis of the foregoing, in reliance thereon and with the foregoing qualifications, we are of the opinion that: 1. The Company has been duly incorporated and is a validly existing corporation in good standing under the laws of the State of California. 2. The Agreements have been duly and validly authorized, executed and delivered by the Company and constitute valid and binding agreements of the Company enforceable against the Company in accordance with their terms, except as rights to indemnity under section 9 of the Reorganization Agreement may be limited by applicable laws and except as enforcement may be limited by applicable bankruptcy, insolvency, reorganization, arrangement, moratorium or other similar laws affecting creditors' rights, and subject to general equity principles and to limitations on availability of equitable relief, including specific performance. 3. The Shares, when issued in accordance with the terms of the Reorganization Agreement, will be duly authorized, validly issued, fully paid and non-assessable. 4. The execution and delivery of the Agreements by the Company pursuant thereto do not violate any provision of the Company's Amended and Restated Articles of Incorporation or Bylaws, and do not constitute a material default under the provisions of any material agreement known to us to which the Company is a party or by which it is bound, and do not violate or contravene (a) any 119 governmental statute, rule or regulation applicable to the Company or (b) any order, writ, judgment, injunction, decree, determination or award which has been entered against the Company and of which we are aware, the violation or contravention of which would materially and adversely affect the Company, its assets, financial condition or operations. 5. To the best of our knowledge, there is no action, proceeding or investigation pending or overtly threatened against the Company before any court or administrative agency that questions the validity of the Agreements or might result, either individually or in the aggregate, in any material adverse change in the assets, financial condition, or operations of the Company. All consents, approvals, authorizations, or orders of, and filings, registrations, and qualifications with any regulatory authority or governmental body in the United States required for the consummation by the Company of the transactions contemplated by the Agreements, have been made or obtained. Registration #33-__________ (the "Registration Statement") filed pursuant to the Securities Act of 1933, as amended (the "Securities Act"), has become effective, and, to the best of our knowledge, no stop order suspending the effectiveness of the Registration Statement or preventing the use of the associated Prospectus/Proxy Statement has been issued and no proceedings for that purpose have been instituted or are pending or threatened by the Securities and Exchange Commission. The Registration Statement and the Prospectus/Proxy Statement (except for the financial statements and schedules, other financial information and statistical data which are included therein and information concerning Ibex, as to which we express no opinion) comply as to form in all material respects with the requirements of the Securities Act and the rules and regulations thereunder. 120 This opinion is intended solely for your benefit and is not to be made available to or be relied upon by any other person, firm, or entity without our prior written consent.

RECITALS A. Castelle, Ibex, and the Shareholders are entering into an Agreement and Plan of Reorganization of even date herewith (the "Reorganization Agreement"), pursuant to which Ibex shall be merged into Castelle and Ibex shareholders shall exchange their stock in Ibex for shares of Castelle. B. The Reorganization Agreement contemplates the establishment of an escrow arrangement to secure the indemnification and other obligations of Ibex and the Shareholders under the Reorganization Agreement and various related agreements. C. Pursuant to Section 10.1 of the Reorganization Agreement, the Designated Shareholders have appointed the Designated Shareholders' Agent as their attorneys-in-fact for the purposes of this Agreement. D. The Designated Shareholders have agreed to deposit ten percent (10%) of the total number of shares of Common Stock of Castelle received pursuant to the Reorganization Agreement (the "Shares") with Escrow Agent in connection with the Designated Shareholders' performance of their obligations under the Reorganization Agreement. E. The Designated Shareholders' Agent and Castelle desire that Escrow Agent hold the Shares pursuant to the terms hereof and to distribute such Shares in accordance with the procedures specified herein. AGREEMENT The parties to this Escrow Agreement, intending to be legally bound, agree as follows: SECTION 1. DEFINED TERMS Capitalized terms used and not otherwise defined in this Escrow Agreement shall have the meanings assigned to them in the Reorganization Agreement. 124 SECTION 2. ESCROW 2.1 Shares and Stock Powers to be Placed in Escrow. On the Closing Date, (i) Castelle shall issue certificates for the Shares in the names of the Designated Shareholders evidencing the shares of Castelle Stock to be held in escrow in accordance with this Escrow Agreement, and (ii) the Designated Shareholders shall deliver to Escrow Agent three stock powers each endorsed by the Designated Shareholders in blank (the "Stock Powers"). Ibex and the Designated Shareholders' Agent shall ensure that all signatures on the Stock Powers delivered to Escrow Agent in accordance with the preceding sentence have been guaranteed by a national bank or New York Stock Exchange member firm. The shares and Stock Powers referred to in this Section 2.1 shall be held by Escrow Agent in escrow (the "Escrow") in accordance with the provisions of this Escrow Agreement. 2.2 Voting of Shares. The record owner of the Shares shall be entitled to exercise all voting rights with respect to such Shares. 2.3 Dividends, Etc. Any cash, securities or other property distributable (whether by way of dividend, stock split or otherwise) in respect of or in exchange for any Shares shall not be distributed to the record owner of such Shares, but rather shall be held by the Escrow Agent in the Escrow. At the time any Shares are required to be released from the Escrow to any person pursuant to this Escrow Agreement, any cash, securities or other property previously distributed in respect of or in exchange for such shares shall be released from the Escrow to such person. 2.4 Transferability. The interests of the Designated Shareholders' Agent and the Shareholders in the Escrow and in the Shares held in the Escrow shall not be assignable or transferable, other than by operation of law. No transfer of any of such interests by operation of law shall be recognized or given effect until Castelle shall have received written notice of such transfer. 2.5 Fractional Shares. No fractional shares of Castelle Stock shall be retained in or released from the Escrow pursuant to this Escrow Agreement. In connection with any release of shares from the Escrow, Castelle shall make a cash payment to the owner of record for such fractional share which payment shall be determined utilizing the Stipulated Value of such Share. 2.6 Receipt By Escrow Agent. Escrow Agent acknowledges receipt from Castelle of a certificate representing the Shares and from the Designated Shareholders' Agent of stock powers executed in blank by the Designated Shareholders with respect to the Shares. Escrow Agent accepts appointment hereunder and agrees to hold and distribute the Shares in accordance herewith. SECTION 3. CLAIM PROCEDURES Claim Procedures shall be as set forth in Section 9 of the Reorganization Agreement and this Section. 125 3.1 Response Notice. Within twenty (20) business days after the delivery of an Officer's Certificate to the Designated Shareholders' Agent (with a copy to the Escrow Agent), the Designated Shareholders' Agent shall deliver to Escrow Agent and Castelle a written notice (the "Response Notice") containing: (i) instructions to the effect that Shares having a Stipulated Value (as defined in Section 5 of this Escrow Agreement) equal to the entire Claim Amount set forth in such Claim Notice are to be released from the Escrow to Castelle; or (ii) instructions to the effect that Shares having a Stipulated Value equal to a specified portion (but not the entire amount) of the Claim Amount set forth in such Claim Notice are to be released from the Escrow to Castelle, together with a statement that the remaining portion of such Claim Amount is being disputed; or (iii) a statement that the entire Claim Amount set forth in such Claim Notice is being disputed. If no Response Notice is received by Escrow Agent from the Designated Shareholders' Agent within twenty (20) business days after the delivery of an Officer's Certificate to the Designated Shareholders' Agent, then the recipient of such Claim Notice shall be deemed to have given instructions that Shares having a Stipulated Value equal to the entire Claim Amount set forth in such Claim Notice are to be released to Castelle from the Escrow. 3.2 Release of Shares to Castelle. (a) If the Designated Shareholders' Agent gives (or is deemed to have given) instructions that shares of Castelle Stock having a Stipulated Value equal to the entire Claim Amount set forth in an Officer's Certificate are to be released from the Escrow to Castelle, then Escrow Agent shall be authorized to use a Stock Power held in the Escrow to transfer to Castelle, from the Escrow, Shares having a Stipulated Value equal to such Claim Amount. (b) If a Response Notice delivered by the Designated Shareholders' Agent in response to an Officer's Certificate contains instructions to the effect that Shares having a Stipulated Value equal to a specified portion (but not the entire amount) of the Claim Amount set forth in such Officer's Certificate are to be released from the Escrow to Castelle, then (i) Escrow Agent shall be authorized to use a Stock Power held in the Escrow to transfer to Castelle, from the Escrow, Shares having a Stipulated Value equal to such specified portion of such Claim Amount, and (ii) the procedures set forth in Section 3.2(c) of this Escrow Agreement shall be followed with respect to the remaining portion of such Claim Amount. (c) If a Response Notice delivered by the Designated Shareholders' Agent in response to a Claim Notice contains a statement that all or a portion of the Claim Amount set forth in such Claim Notice is being disputed (such Claim Amount or the disputed portion thereof being referred to as the "Disputed Amount"), then, notwithstanding anything contained in Section 4 of this Escrow Agreement, Escrow Agent shall continue to hold in the Escrow (in addition to any other Shares permitted to be retained in the Escrow, whether in connection with any other dispute, or otherwise) Shares having a Stipulated Value equal to 125% of the Disputed Amount. Such Shares shall continue to be held in the Escrow until such time as (i) Castelle and the Designated Shareholders' Agent execute a settlement agreement containing instructions regarding the release of such Shares, (ii) Escrow Agent receives a written decision from the arbitrator assigned to the dispute and an application to correct or vacate the arbitration award can no longer be 126 filed pursuant to the terms of the Reorganization Agreement, or (iii) Escrow Agent receives a copy of a court order containing instructions to Escrow Agent regarding the release of such Shares. Escrow Agent shall thereupon release such Shares from the Escrow in accordance with the instructions set forth in such settlement agreement, arbitration decision or court order. (The parties acknowledge that it is appropriate to retain more than 100% of the Claim Amount in the Escrow in recognition of the fact that Castelle may have underestimated the aggregate amount of the actual and potential Damages arising from a particular breach.) SECTION 4. RELEASE OF SHARES TO DESIGNATED SHAREHOLDERS' AGENT 4.1 Shares to be Released. On the date 365 days after the Closing Date, Escrow Agent shall release to the Designated Shareholders' Agent from the Escrow all Shares then held in the Escrow, except for any Shares subject to an Officer's Certificate which has been delivered or that are to be retained in the Escrow in accordance with Section 3.2(c) of this Escrow Agreement. 4.2 Procedures for Releasing Shares.

SECTION 5. VALUATION OF SHARES HELD IN ESCROW For purposes of this Escrow Agreement, the "Stipulated Value" of each of the Shares held in the Escrow shall be deemed to be equal to $8.00 (adjusted as appropriate to reflect any stock split, reverse stock split, stock dividend or similar transaction effected by Castelle after the Closing Date). SECTION 6. FEES AND EXPENSES The Shareholders shall reimburse the Designated Shareholders' Agent for all reasonable expenses (including attorneys' fees) incurred by the Designated Shareholders' Agent in connection with the performance of his duties hereunder. In addition, the Designated Shareholders' Agent shall be promptly reimbursed by the Designated Shareholders, in proportion to the number of shares of Castelle Common Stock received by each of them as a result of the Merger, for any payments which the Designated Shareholders' Agent is obligated to make and which are made to the Escrow Agent pursuant to the indemnification provisions of this Escrow Agreement. 127 SECTION 7. PAYMENT OF ESCROW AGENT'S FEES AND EXPENSES All fees and expenses (including, without limitation, reasonable attorneys' fees) charged by Escrow Agent for its activities pursuant to this Agreement shall be paid by Castelle pursuant to the attached fee schedule.

Escrow Agent may resign as Escrow Agent at any time by notice to the Designated Shareholders' Agent and Castelle (the "Resignation Notice"). Upon receipt of the Resignation Notice, the Designated Shareholders' Agent and Castelle shall appoint a successor Escrow Agent, which shall be a banking corporation or trust company, organized under the laws of the United States or of the State of California, with a place of business in San Francisco. Upon receipt of notice of appointment from the Designated Shareholders' Agent and Castelle, Escrow Agent shall promptly deliver the Shares to such successor. In the event the Designated Shareholders' Agent and Castelle do not agree upon a successor and deliver written notice thereof to Escrow Agent within 60 days following delivery of the Resignation Notice, the Presiding Judge of the Superior Court of the State of California, in and for the City and County of San Francisco, shall appoint a successor in accordance with the above-mentioned guidelines, and Escrow Agent shall promptly deliver the Shares to such successor. 8.2 Indemnification.
