I further acknowledge that all inventions, original works of authorship, developments, concepts, know-how, improvements or trade secrets made by me (solely or jointly with others) within the scope of and during the period of my relationship with the Company are “works made for hire” (to the greatest extent permitted by applicable law) and are compensated by my salary (if I am or was a Company employee) or by such amounts paid to me under any applicable consulting agreement or consulting arrangements (if I am or was a Company consultant), unless regulated otherwise by the mandatory law of the state of California.

I agree to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions and any copyrights, patents, trademarks, maskwork rights, moral rights, or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments, recordations, and all other instruments which the Company shall deem necessary in order to apply for, obtain, maintain and transfer such rights and in order to assign and convey to the Company, its successors, assigns and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, maskwork rights or other intellectual property rights relating thereto.

Escrow Agreement

This Escrow Agreement (the “Agreement”) is entered into as of March , 2004, by and among Tarantella, Inc., a California corporation (“Buyer”), CastStream, Inc., a California corporation (“Seller”), the Securityholder Agent whose signature appears on the signature page hereof (the “Securityholder Agent”) and Xxxxx Fargo Bank, National Association (“Escrow Agent”).

RECITALS

Buyer, the Seller and certain Shareholders entered into a Stock Exchange Agreement dated as of March 29, 2004 (the “Purchase Agreement”), pursuant to which Tarantella acquired all of the capital stock of the Seller from the Shareholders. The Purchase Agreement provides that the escrow fund provided for hereby will secure the indemnification obligations of the Seller and the Shareholders (as defined in the Purchase Agreement) to Buyer and its affiliates, officers, directors, employees, representatives and agents under the Purchase Agreement, on the terms and conditions set forth herein. Pursuant to the Purchase Agreement, Buyer will deliver to Escrow Agent, on behalf of the Shareholders, shares of Buyer’s Common Stock, which is to be deposited into the escrow fund provided for hereby. The parties desire to establish the terms and conditions pursuant to which such escrow fund will be established and maintained.

AGREEMENT

The parties agree as follows:

1. Defined Terms. Capitalized terms used in this Agreement and not otherwise defined shall have the meanings given them in the Purchase Agreement.

2. Escrow and Indemnification.

(a) Escrow Fund. As soon as practicable after March 30, 2004 (the “Closing Date”), Buyer shall deposit with Escrow Agent several certificates representing 100,000 shares of Buyer Common Stock and warrant documents (“Warrants”) representing 100,000 shares of Buyer Common Stock (the “Warrant Shares”), pursuant to Section 1.2 of the Purchase Agreement (the Buyer Common Stock and the Warrant Shares collectively being referred to as the “Exchange Shares” and, as so deposited, the “Escrow Fund”). The Escrow Fund shall be held as a trust fund and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any party hereto. Escrow Agent agrees to accept delivery of the Escrow Fund and to hold such Escrow Fund in escrow subject to the terms and conditions of this Agreement.

(b) Indemnification. Each of the Seller and the Shareholders has agreed in Article 4 of the Purchase Agreement to indemnify and hold harmless Buyer and each Indemnified Party from and against Losses. The Escrow Fund shall be security for the indemnity obligations of Seller and the Shareholders, subject to the limitations, and in the manner provided, in this Agreement.

3. Administration of Escrow Fund. Escrow Agent shall administer the Escrow Fund as follows:

(a) Escrow Agent shall hold and safeguard the Escrow Fund during the Escrow Period (as defined in Section 5 below), shall treat such fund as a trust fund in accordance with the terms of this Agreement and not as the property of Buyer and shall hold and dispose of the Escrow Fund only in accordance with the terms hereof.

(b) Upon receipt by Escrow Agent at any time on or before the last day of the Escrow Period of a certificate signed by any officer of Buyer (an “Officer’s Certificate”):

(i) stating that Buyer or any other Indemnified Person has paid or reasonably anticipates that it will have to pay or incur Losses, and

(ii) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid or incurred, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or claim to which such item is related, Escrow Agent shall, subject to the provisions of Section 3(c) below, deliver to Buyer out of the Escrow Fund, as promptly as practicable, the number of Exchange Shares claimed in such Officer’s Certificate. The Exchange Shares so delivered will be withdrawn on a pro rata basis from the Exchange Shares of each Shareholder. As between the Buyer Common Stock and the Warrant Shares, Escrow Agent shall deliver shares of Buyer Common Stock to Buyer until such time as such Buyer Common Stock is exhausted, at which time the Escrow Agent shall deliver the Warrants representing the number of Warrant Shares equal to such losses. Buyer will provide a written letter of instruction to Escrow Agent contemporaneously with any Officer’s Certificate that will specify delivery instructions.

(iii) For the purpose of compensating Buyer or any Indemnified Person for its Losses pursuant to this Agreement, the value per share of the Exchange Shares (i.e., of the Buyer Common Stock and the Warrant Shares comprising the Escrow Fund) shall be the average closing price of Buyer Common Stock for the five trading days immediately prior to the Closing Date. Buyer shall set forth in any Officer’s Certificate delivered to the Escrow Agent pursuant to Section 3(b)(ii) above the value per share of the Exchange Shares calculated pursuant to the provisions of this Section 3(b)(iii) and the corresponding number of shares of Buyer Common Stock or Warrant Shares to be delivered from the Escrow Fund.

(c) Notice of Claims. At the time of delivery of any Officer’s Certificate to Escrow Agent, a duplicate copy of such certificate shall be delivered to Securityholder Agent (as set forth below) and for a period of 10 days after receipt of the Officer’s Certificate, Escrow Agent shall make no delivery to Buyer from the Escrow Fund pursuant to Section 3(b) hereof unless Escrow Agent shall have received written authorization from Securityholder Agent to make such delivery within such 10 day period. After the expiration of such 10 day period, Escrow Agent shall make delivery of the requested number of Exchange Shares from the Escrow Fund in accordance with Section 3(b) hereof, provided that no such payment or delivery may be

made if Securityholder Agent shall object, in a written statement to the claim made in the Officer’s Certificate, and such statement shall have been delivered to Escrow Agent and Buyer prior to the expiration of such 10 day period.

(d) Replacement Certificates. After delivery of Exchange Shares to Buyer pursuant to Section 3(b), Buyer shall deposit with Escrow Agent several certificates and/or warrant documents, as appropriate, representing the remaining Exchange Shares after deducting the Exchange Shares delivered to date to Buyer in respect to all Indemnified Claims.

(e) Securityholder Agent of the Shareholders; Power of Attorney.

(i) Pursuant to the terms of the Purchase Agreement, upon the Closing, and without further act of any Shareholder, Xxxxxxx Xxxxxxxxx shall be appointed as agent and attorney-in-fact for and on behalf of himself and the other Shareholders (the “Securityholder Agent”), and is authorized to enter into this Escrow Agreement, to give and receive notices and communications regarding the delivery to Buyer of any property or securities from the Escrow Fund in satisfaction of claims by Buyer, negotiate, enter into settlements and compromises of, and comply with orders of courts and awards of arbitrators with respect to such claims, and to take all actions necessary or appropriate in the judgment of Securityholder Agent for the accomplishment of the foregoing

(ii) The Securityholder Agent shall not be liable for any act done or omitted hereunder as Securityholder Agent while acting in good faith and in the exercise of reasonable judgment.

(iii) Actions of the Securityholder Agent. A decision, act, consent or instruction of the Securityholder Agent shall constitute a decision of the Shareholders and shall be final, binding and conclusive, and the Escrow Agent and Buyer may rely upon any such decision, act, consent or instruction of the Securityholder Agent as being the decision, act, consent or instruction of each Shareholder. The Escrow Agent and Buyer are hereby relieved from any liability to any Person for any acts done by them or each of them in accordance with such decision, act, consent or instruction of the Securityholder Agent.

(f) Resolution of Conflicts; Arbitration.

(i) In case Securityholder Agent shall object timely in writing to any claim or claims made in any Officer’s Certificate as not being a claim that is properly an Indemnified Claim, Buyer and Securityholder Agent shall attempt in good faith to agree upon the rights of the respective parties with respect to each of such claims for a period of 30 days after Escrow Agent’s receipt of Seller’s written objection to the claim pursuant to Section 3(c) (the “Negotiation Period”). If Buyer and Securityholder Agent should so agree during the Negotiation Period, a memorandum setting forth such agreement shall be prepared and signed by both parties and shall be furnished to Escrow Agent. Escrow Agent shall be entitled to rely on any such memorandum and distribute the Exchange Shares from the Escrow Fund in accordance with the terms thereof.

(ii) If no such agreement has been reached by the end of the Negotiation Period, either Buyer or Securityholder Agent may demand arbitration of the matter unless the amount of the Losses is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained by settlement or a non-appealable decision of a court of competent jurisdiction or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by a single arbitrator, selected by mutual agreement of the parties or otherwise in accordance with the then prevailing rules of the American Arbitration Association as adopted by the State of California. The arbitration shall be conducted in the City of San Jose, California. The written decision of the arbitrator as to the validity and amount of any claim in such Officer’s Certificate shall be binding and conclusive upon the parties to this Agreement, and notwithstanding anything in Section 3(c) hereof, Escrow Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Escrow Fund in accordance therewith. The arbitrator shall award reimbursement to the prevailing party in the arbitration of its reasonable expenses of the arbitration (including costs and reasonable attorneys’ fees). The award of the arbitrator shall be the sole and exclusive monetary remedy of the parties and shall be enforceable in any court of competent jurisdiction. Notwithstanding the foregoing, any party shall be entitled to seek injunctive relief or other equitable remedies from any court of competent jurisdiction.

4. Third-Party Claims. In the event Buyer becomes aware of a third-party claim which Buyer believes may result in a demand against the Escrow Fund, Buyer shall notify Securityholder Agent and Seller of such claim, and the Seller and Shareholders shall be entitled, at their expense, to participate in any defense of such claim; provided, however, that failure to so notify Securityholder Agent or Seller shall not relieve Shareholders or the Seller from any liability they have under this Agreement or the Purchase Agreement with respect to such third party claim. Buyer shall have the right in its discretion to settle any such claim. In the event that Securityholder Agent has consented in writing to any such settlement, the Shareholders shall have no power or authority to object under any provision hereof or Article 4 of the Purchase Agreement to the amount of any claim by Buyer against the Escrow Fund consistent with such settlement.

5. Release of Escrow Fund. Subject to the following requirements, the Escrow Fund shall remain in existence from the Closing Date until the first anniversary of the Closing Date at 11:59 p.m. Pacific Time (the “Escrow Period”). Upon the expiration of the Escrow Period (the “Escrow Termination Date”), all Exchange Shares then remaining in the Escrow Fund shall be delivered to Securityholder Agent for distribution to the Shareholders; provided, however, that a number of Exchange Shares, which, in the reasonable judgment of Buyer (as set forth in a written notice delivered to the Escrow Agent), are necessary to satisfy any unsatisfied claims specified in any Officer’s Certificate delivered to Escrow Agent prior to the Escrow Termination Date shall remain in the Escrow Fund (and the Escrow Fund shall remain in existence) until such claims have been resolved. As soon as all such claims have been resolved (as evidenced by a joint written notice delivered to Escrow Agent from Buyer and Seller), Escrow Agent shall deliver to Securityholder Agent for delivery to the Shareholders all Exchange Shares then remaining in the Escrow Fund.

6. Escrow Agent’s Duties.

(a) Buyer, Seller and the Securityholder Agent acknowledge and agree that Escrow Agent (i) shall not be responsible for any of the agreements referred to herein, including the Purchase Agreement, but shall be obligated only for the performance of such duties as are specifically set forth in this Agreement and as set forth in any additional written escrow instructions which Escrow Agent may receive after the date of this Agreement that are signed by an officer of Buyer and Seller and the Securityholder Agent on behalf of the Shareholders; (ii) shall not be obligated to take any legal or other action hereunder which might in its reasonable judgment involve expense or liability unless it shall have been furnished with indemnity reasonably acceptable to it; and (iii) may rely on and shall be protected in acting or refraining from acting upon any written notice, instruction, instrument, statement, request or document furnished to it hereunder and reasonably believed by it to be genuine and to have been signed or presented by the proper person, and shall have no responsibility for determining the accuracy thereof.

(b) Escrow Agent is hereby expressly authorized to disregard any and all warnings given by any of the parties hereto or by any other person, excepting only orders or process of courts of law or written decision of arbitrators pursuant to Section 3, and is hereby expressly authorized to comply with and obey orders, judgments or decrees of any court or written decision of arbitrators. In case Escrow Agent obeys or complies with any such order, judgment or decree of any court or written decision of arbitrators, Escrow Agent shall not be liable to any of the parties hereto or to any other person by reason of such compliance, notwithstanding any such order, judgment or decree being subsequently reversed, modified, annulled, set aside, vacated or found to have been entered without jurisdiction.

(c) Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder.

(d) Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with Escrow Agent.

(e) Neither Escrow Agent nor any of its directors, officers or employees shall be liable to anyone for any action taken or omitted to be taken by it or any of its directors, officers or employees hereunder except in the case of gross negligence, bad faith or willful misconduct. Subject to Section 6(g) below, Buyer, Seller and the Shareholders (collectively, the “Indemnifying Parties”) covenant and agree to jointly and severally indemnify Escrow Agent and hold it harmless from and against any fee, loss, liability or expense (including reasonable attorney’s fees and expenses) (a “Loss”) incurred by Escrow Agent arising out of or in connection with the performance of its obligations in accordance with the provisions of this Agreement or with the administration of its duties hereunder, unless such Loss shall arise out of or be caused by Escrow Agent’s gross negligence, bad faith or willful misconduct; provided, however, that indemnification for Escrow Agent’s standard fees and expenses set forth on the fee schedule attached hereto as Exhibit A shall be borne exclusively by Buyer.

(f) To the extent that Escrow Agent becomes liable for the payment of any taxes in respect of payments made hereunder, Escrow Agent shall satisfy such liability to the extent possible from the Escrow Fund. Subject to Section 6(g) below, the Indemnifying Parties agree to jointly and severally indemnify and hold Escrow Agent harmless from and against any taxes, additions for late payment, interest, penalties and other expenses, that may be assessed against Escrow Agent on any payment or other activities under this Agreement unless any such tax, addition for late payment, interest, penalty or other expense shall arise out of or be caused by the grossly negligent actions of, or a grossly negligent failure to act by, Escrow Agent.

(g) Notwithstanding the joint and several nature of the obligations of Indemnifying Parties under Section 6(e) and 6(f), the Shareholders’ total liability for indemnification of Escrow Agent under Sections 6(e) and 6(f) hereof (the “Indemnification Liability”) shall in no event exceed the value of the Escrow Fund then available to pay such liability. Any and all amounts to be paid by Seller for the Indemnification Liability shall be payable only out of the Escrow Fund.

(h) Escrow Agent may resign at any time upon giving at least 30 days’ written notice to Buyer, Seller and Securityholder Agent; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent, which shall be accomplished as follows: Buyer, Seller and Securityholder Agent shall use their best efforts to mutually agree upon a successor agent within 30 days after receiving such notice. If the parties fail to agree upon a successor escrow agent within such time, Securityholder Agent with the consent of Buyer, which shall not be unreasonably withheld, shall have the right to appoint a successor escrow agent authorized to do business in California. The successor escrow agent selected in the preceding manner shall execute and deliver an instrument accepting such appointment and it shall thereupon be deemed Escrow Agent hereunder and it shall without further acts be vested with all the estates, properties, rights, powers, and duties of the predecessor Escrow Agent as if originally named as Escrow Agent. If no successor escrow agent is named, Escrow Agent may apply to a court of competent jurisdiction for the appointment of a successor escrow agent. Thereafter, the predecessor Escrow Agent shall be discharged from any further duties and liabilities under this Agreement. The provisions of Sections 6(e) and 6(f) shall survive the resignation or removal of Escrow Agent or the termination of this Agreement.

(i) In the event of any disagreement between any of the parties (other than Escrow Agent) to this Agreement, or between them or any of them and any other person or entity resulting in conflicting or adverse claims or demands being made in connection with the Escrow Funds, or in the event that Escrow Agent, in good faith, shall be in doubt as to what action it should take hereunder, Escrow Agent at its option may refuse to comply with any claims or demands on it, or refuse to take any other action hereunder, so long as such disagreement continues or such doubt exists, and, in any such event, Escrow Agent shall not be or become liable in any way or to any person or entity for its failure or refusal to act, and Escrow Agent shall be entitled to either:

(i) continue so to refrain from acting until (A) the rights of all parties shall have been determined by a final and non-appealable order of a court of competent jurisdiction or by a final and non-appealable award of arbitrators, or (B) all differences shall have been resolved by agreement among all of the interested persons or entities, and Escrow Agent shall have been notified thereof in writing signed by all such persons or entities, or

(ii) file an interpleader action in any court of competent jurisdiction.

upon surrender of the Warrant, together with delivery of the duly executed Warrant exercise form attached hereto as Appendix A (the “Exercise Agreement”) and payment by cash, certified check or wire transfer of funds for the aggregate Warrant Price for that number of Warrant Shares then being purchased, to the Company during normal business hours on any business day at the Company’s principal executive offices (or such other office or agency of the Company as it may designate by notice to the holder hereof). The Warrant Shares so purchased shall be deemed to be issued to the holder hereof or such holder’s designee, as the record owner of such shares, as of the close of business on the date on which this Warrant shall have been surrendered (or evidence of loss, theft or destruction thereof and security or indemnity satisfactory to the Company), the Warrant Price shall have been paid and the completed Exercise Agreement shall have been delivered. Certificates for the Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall be delivered to the holder hereof within a reasonable time, not exceeding three (3) business days, after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the holder hereof and shall be registered in the name of such holder or such other name as shall be designated by such holder. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of such certificates, deliver to the holder a new Warrant representing the number of shares with respect to which this Warrant shall not then have been exercised. As used herein, “business day” means a day, other than a Saturday or Sunday, on which banks in New York City are open for the general transaction of business. Prior to the registration of the Warrant Shares, each exercise hereof shall constitute the re-affirmation by the Warrantholder that the representations and warranties contained in Section 2.15, Investment Representations, of the Stock Exchange Agreement, dated March 2004 (the “Exchange Agreement”), among the Company the original holder of the Warrant and the original holders of the other Company Warrants (as defined below) are true and correct in all material respects with respect to the Warrantholder as of the time of such exercise.

Section 4. Compliance with the Securities Act of 1933. The Company may cause the legend set forth on the first page of this Warrant to be set forth on each Warrant or similar legend on any security issued or issuable upon exercise of this Warrant, unless counsel for the Company is of the opinion as to any such security that such legend is unnecessary.

Section 5. Payment of Taxes. The Company will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the registered holder of this Warrant in respect of which such shares are issued, and in such case, the Company shall not be required to issue or deliver any certificate for Warrant Shares or any Warrant until the person requesting the same has paid to the Company the amount of such tax or has established to the Company’s reasonable satisfaction that such tax has been paid. The holder shall be responsible for income taxes due under federal, state or other law, if any such tax is due.

Section 6. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen, or destroyed, the Company shall issue in exchange and substitution of and

-4-

upon cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with respect thereto, if requested by the Company.

Section 7. Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the Company shall at all applicable times keep reserved until issued (if necessary) as contemplated by this Section 7, out of the authorized and unissued shares of Common Stock, sufficient shares to provide for the exercise of the rights of purchase represented by this Warrant. The Company agrees that all Warrant Shares issued upon due exercise of the Warrant shall be, at the time of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company.

Section 8. Adjustments. Subject and pursuant to the provisions of this Section 8, the Warrant Price and number of Warrant Shares subject to this Warrant shall be subject to adjustment from time to time as set forth hereinafter.

(a) If the Company shall, at any time or from time to time while this Warrant is outstanding, pay a dividend or make a distribution on its Common Stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its outstanding shares of Common Stock into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the Company is the continuing corporation), then the number of Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in effect immediately prior to the date upon which such change shall become effective, shall be adjusted by the Company so that the Warrantholder thereafter exercising the Warrant shall be entitled to receive the number of shares of Common Stock or other capital stock which the Warrantholder would have received if the Warrant had been exercised immediately prior to such event upon payment of a Warrant Price that has been adjusted to reflect a fair allocation of the economics of such event to the Warrantholder. Such adjustments shall be made successively whenever any event listed above shall occur.

(b) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation in which the Company is not the survivor, or sale, transfer or other disposition of all or substantially all of the Company’s assets to another corporation shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification,

-5-

consolidation, merger, sale, transfer or other disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitation, provision for adjustment of the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise thereof. The Company shall not effect any such consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume the obligation to deliver to the holder of the Warrant, at the last address of such holder appearing on the books of the Company, such shares of stock, securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to purchase, and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, sales, transfers or other dispositions.

(c) In case the Company shall fix a payment date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company is the continuing corporation) of evidences of indebtedness or assets (other than cash dividends or cash distributions payable out of consolidated earnings or earned surplus or dividends or distributions referred to in Section 8(a)), or subscription rights or warrants, the Warrant Price to be in effect after such payment date shall be determined by multiplying the Warrant Price in effect immediately prior to such payment date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Market Price (as defined below) per share of Common Stock immediately prior to such payment date, less the fair market value (as determined by the Company’s Board of Directors in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common Stock outstanding multiplied by such Market Price per share of Common Stock immediately prior to such payment date. “Market Price” as of a particular date (the “Valuation Date”) shall mean the following: (a) if the Common Stock is then listed on a national stock exchange, the closing sale price of one share of Common Stock on such exchange on the last trading day prior to the Valuation Date; (b) if the Common Stock is then quoted on The Nasdaq Stock Market, Inc. (“Nasdaq”), the closing sale price of one share of Common Stock on Nasdaq on the last trading day prior to the Valuation Date or, if no such closing sale price is available, the average of the high bid and the low asked price quoted on Nasdaq on the last trading day prior to the Valuation Date; or (c) if the Common Stock is not then listed on a national stock exchange or quoted on Nasdaq, the fair market value of one share of Common Stock as of the Valuation Date, shall be determined in good faith by the Board of Directors of the Company and the Warrantholder. If the Common Stock is not then listed on a national securities exchange or quoted on Nasdaq, the Board of Directors of the Company shall respond promptly, in writing, to an inquiry by the Warrantholder prior to the exercise hereunder as to the fair market value of a share of Common Stock as determined by the Board of Directors of the Company. In the event that the Board of Directors of the Company and the Warrantholder are unable to agree upon the fair market value in respect of subpart (c) hereof, the Company and the Warrantholder shall jointly select an appraiser, who is experienced in such matters. The decision

-6-

of such appraiser shall be final and conclusive, and the cost of such appraiser shall be borne evenly by the Company and the Warrantholder. Such adjustment shall be made successively whenever such a payment date is fixed.

(d) An adjustment to the Warrant Price shall become effective immediately after the payment date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment.

(e) In the event that, as a result of an adjustment made pursuant to this Section 8, the holder of this Warrant shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant Shares contained in this Warrant.

Section 9. Fractional Interest. The Company shall not be required to issue fractions of Warrant Shares upon the exercise of this Warrant. If any fractional share of Common Stock would, except for the provisions of the first sentence of this Section 9, be deliverable upon such exercise, the Company, in lieu of delivering such fractional share, shall pay to the exercising holder of this Warrant an amount in cash equal to the Market Price of such fractional share of Common Stock on the date of exercise.

Section 10. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the sole and exclusive benefit of the Company and the Warrantholder.

Section 11. Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall promptly give written notice thereof to the Warrantholder at the address appearing in the records of the Company, stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Failure to give such notice to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment.

Section 12. Identity of Transfer Agent. The Transfer Agent for the Common Stock is Equiserve. Upon the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company will mail to the Warrantholder a statement setting forth the name and address of such transfer agent.

Section 13. Notices. Unless otherwise provided, any notice required or permitted under this Warrant shall be given in writing and shall be deemed effectively given as hereinafter described (i) if given by personal delivery, then such notice shall be deemed given upon such delivery, (ii) if given by telex or facsimile, then such notice shall be deemed given upon receipt of confirmation of complete transmittal, (iii) if given by mail, then such notice shall

-7-

be deemed given upon the earlier of (A) receipt of such notice by the recipient or (B) three days after such notice is deposited in first class mail, postage prepaid, and (iv) if given by an internationally recognized overnight air courier, then such notice shall be deemed given one day after delivery to such carrier. All notices shall be addressed to the Warrantholder at his, hers or its address as set forth in the Company’s books and records and, if to the Company, at the address as follows:

Tarantella, Inc.

000 Xxxxxxx Xxxxxx

Xxxxx Xxxx, Xxxxxxxxxx 00000

Attention: Legal Department

Fax: (000) 000-0000

or at such other address as the Warrantholder or the Company may designate upon ten days’ advance written notice to the other.

Section 14. Registration Rights. The initial holder of this Warrant is entitled to the benefit of certain registration rights with respect to the shares of Common Stock issuable upon the exercise of this Warrant as provided in the Registration Rights Agreement, and any subsequent holder hereof may be entitled to such rights.

Section 15. Successors. All the covenants and provisions hereof by or for the benefit of the Warrantholder shall bind and inure to the benefit of its respective successors and assigns hereunder.

Section 16. Governing Law. This Warrant shall be governed by, and construed in accordance with, the internal laws of the State of California, without reference to the choice of law provisions thereof. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably submits to the exclusive jurisdiction of the courts of the State of California located in Santa Xxxxx County and the United States District Court for the Northern District of California for the purpose of any suit, action, proceeding or judgment relating to or arising out of this Warrant and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world by the same methods as are specified for the giving of notices under this Warrant. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such court. The Company and, by accepting this Warrant, the Warrantholder, each irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

Section 17. Limitation on Exercise. Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by the Warrantholder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited (the “Exercise Limit”) to the extent necessary to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned by such Warrantholder and its affiliates and any other persons whose beneficial ownership of Common

-8-

Stock would be aggregated with the Warrantholder’s for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), does not exceed 19.999% of the total number of issued and outstanding shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise). For such purposes, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.

Section 18. No Rights as Stockholder. Prior to the exercise of this Warrant, the Warrantholder shall not have or exercise any rights as a stockholder of the Company by virtue of its ownership of this Warrant.

Section 19. Section Headings. The section headings in this Warrant are for the convenience of the Company and the Warrantholder and in no way alter, modify, amend, limit or restrict the provisions hereof.

IN WITNESS WHEREOF, the Company has caused this Warrant to be duly executed, as of the day of March , 2004.
