Definitive Merger Prospectus

The filing fee of $2,973.42 was calculated pursuant to Exchange Act Rule 0-11(c) and is equal to $117.70 per million of the aggregate merger consideration of $25,262,731.95. The aggregate merger consideration is calculated as the sum of (a) the product of 27,994,937 shares of Tarantella’s common stock and the merger consideration of $0.90 per share in cash and (b) the difference between $0.90 per share and the exercise price per share for each of the 153,348 options outstanding to purchase shares of Tarantella’s common stock that have an exercise price of less than $0.90 per share.

The board of directors of Tarantella, Inc. has approved an Agreement and Plan of Merger dated May 9, 2005, among Sun Microsystems, Inc., Cha Cha Acquisition Corporation, a wholly owned subsidiary of Sun Microsystems, and Tarantella, pursuant to which Cha Cha Acquisition Corporation will merge with and into Tarantella, with Tarantella becoming a wholly owned subsidiary of Sun Microsystems.

If the merger is completed, holders of Tarantella’s common stock will receive $0.90 in cash, without interest, for each share of Tarantella’s common stock they own.

Shareholders of Tarantella will be asked, at a special meeting of Tarantella’s shareholders, to adopt the merger agreement and approve the principal terms of the merger. The board of directors of Tarantella has unanimously approved and declared the merger, the merger agreement and the transactions contemplated by the merger agreement advisable, and has unanimously declared that it is in the best interests of Tarantella’s shareholders that Tarantella enter into the merger agreement and consummate the merger on the terms and conditions set forth in the merger agreement. The board of directors of Tarantella unanimously recommends that Tarantella’s shareholders vote FOR adoption of the merger agreement and approval of the principal terms of the merger.

The date, time and place of the special meeting to consider and vote upon a proposal to adopt the merger agreement and approve the principal terms of the merger are as follows:

The proxy statement attached to this letter provides you with information about the special meeting of Tarantella’s shareholders and the proposed merger. We encourage you to read the entire proxy statement carefully.

Your vote is very important. Whether or not you plan to attend the special meeting, if you are a holder of Tarantella’s common stock please take the time to vote by completing, signing, dating and mailing the enclosed proxy card to us or by voting by phone, fax, or the Internet, if available.

The proxy statement is dated June 10, 2005, and is first being mailed to shareholders of Tarantella on or about June 16, 2005.

A special meeting of shareholders of Tarantella, Inc., a California corporation, will be held on July 6, 2005 at 10:00 a.m., local time, at the Hyatt Regency San Francisco Airport, 1333 Bayshore Highway, Burlingame, California 94010, for the following purposes:

1. To consider and vote upon a proposal to adopt and approve the Agreement and Plan of Merger dated as of May 9, 2005, among Sun Microsystems, Inc., a Delaware corporation, Cha Cha Acquisition Corporation, a California corporation and a wholly owned subsidiary of Sun Microsystems, and Tarantella, Inc. and to approve the principal terms of the merger contemplated thereby; and

2. To transact such other business as may properly come before the special meeting or any adjournment or postponement thereof.

The board of directors of Tarantella has fixed the close of business on June 8, 2005 as the record date for the determination of shareholders entitled to notice of, and to vote at, the special meeting and any adjournment or postponement thereof. Only holders of record of shares of Tarantella’s common stock at the close of business on the record date are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement of it. At the close of business on the record date, Tarantella had outstanding and entitled to vote 27,994,937 shares of common stock. Holders of Tarantella’s common stock are entitled to dissenters’ rights under the California Corporations Code in connection with the merger if they meet certain conditions. See “Dissenters’ Rights” on page 31.

Your vote is important. The affirmative vote of the holders of a majority of the outstanding shares of Tarantella’s common stock is required to adopt the merger agreement and approve the principal terms of the merger. Even if you plan to attend the special meeting in person, we request that you complete, sign, date and return the enclosed proxy and thus ensure that your shares will be represented at the special meeting if you are unable to attend. If you sign, date and mail your proxy card without indicating how you wish to vote, your proxy will be counted as a vote in favor of adoption of the merger agreement and approval of the principal terms of the merger. If you fail to return your Tarantella proxy card, the effect will be that your shares will not be counted for purposes of determining whether a quorum is present at the Tarantella special meeting but will effectively be counted as a vote against adoption of the merger agreement and approval of the principal terms of the merger. If you do attend the special meeting and wish to vote in person, you may withdraw your proxy and vote in person.

By Order of the Board of Directors,

This summary highlights selected information from this proxy statement and may not contain all of the information that is important to you. To understand the merger fully and for a more complete description of the legal terms of the merger, you should read carefully this entire proxy statement and the documents we refer to herein. See “Where You Can Find More Information.” The merger agreement is attached as Annex A to this proxy statement. We encourage you to read the merger agreement as it is the legal document that governs the merger. All information contained in this proxy statement was prepared and supplied by Tarantella, except for the descriptions of the businesses of Sun Microsystems and Cha Cha Acquisition Corporation contained in this summary below under the heading “The Companies” and elsewhere in this proxy statement under the headings “The Companies—Sun Microsystems” and “The Companies—Sun Microsystems Merger Subsidiary,” which descriptions were supplied by Sun Microsystems.

This proxy statement contains “forward-looking statements,” as defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, that are based on our current expectations, assumptions, estimates and projections about our company, our industry and the merger. The forward-looking statements are subject to various risks and uncertainties. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “project,” “should” and similar expressions. Those statements include, among other things, the risk that the merger may not be consummated in a timely manner, if at all, risks regarding employee retention and other risks detailed in our current filings with the Securities and Exchange Commission, including our most recent filings on Form 10-K or Form 10-Q, which discuss these and other important risk factors concerning our operations. We caution you that reliance on any forward-looking statement involves risks and uncertainties, and that although we believe that the assumptions on which our forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and, as a result, the forward-looking statements based on those assumptions could be incorrect. In light of these and other uncertainties, you should not conclude that we will necessarily achieve any plans and objectives or projected financial results referred to in any of the forward-looking statements. We do not undertake to release the results of any revisions of these forward-looking statements to reflect future events or circumstances.

We were incorporated under the name The Santa Cruz Operation, Inc. (“SCO”) in California in 1979. On May 4, 2001, we completed the sale of our Server Software and Professional Services Divisions to Caldera Systems, Inc., retaining the Tarantella Division. Upon the completion of the sale, we changed our corporate name to Tarantella, Inc.

We are a provider of Internet infrastructure software that enables web-based access to enterprise applications from virtually any client device, including personal computers, Apple Macintosh computers, network terminals known as “thin clients” and handheld devices, such as personal digital assistants. The Tarantella Secure Global Desktop Enterprise Edition solution instantly provides managed and secure web access to enterprise mainframe, Windows, AS/400, Linux and UNIX applications. It leverages existing information technology assets to provide cost savings, improved productivity and the flexibility to accommodate the rapid changes in today’s organizations. See “The Companies—Tarantella.”

Cha Cha Acquisition Corporation is a California corporation and a wholly owned subsidiary of Sun Microsystems. Cha Cha Acquisition Corporation was organized solely for the purpose of entering into the merger agreement with Tarantella and completing the merger and has not conducted any business operations. See “The Companies—Sun Microsystems Merger Subsidiary.”

If the merger is completed, you will receive $0.90 in cash, without interest, in exchange for each share of our common stock that you own.

After the merger is completed, you will have the right to receive the merger consideration but you will no longer have any rights as a Tarantella shareholder. Our shareholders will receive the merger consideration after exchanging their Tarantella stock certificates in accordance with the instructions contained in the letter of transmittal to be sent to our shareholders shortly after completion of the merger.

Under the merger agreement, at the effective time of the merger, if you are an employee who is continuing with Sun Microsystems and hold an outstanding employee stock option, whether or not exercisable at the effective time of the merger and regardless of the exercise price, your option will be assumed by Sun Microsystems and will continue to have and be subject to the same terms and conditions set forth in your option. Your outstanding employee stock option will be exercisable for that number of shares of Sun Microsystems’ common stock equal to the product of the number of shares of our common stock issuable upon exercise of your option multiplied by the option ratio, which is the ratio of the value of the per share merger consideration over the average of the closing prices for a share of Sun Microsystems’ common stock on the ten trading days ending one day prior to the closing date. The per share exercise price for the shares of Sun Microsystems’ common stock issuable upon exercise of your assumed stock options will be equal to the amount determined by dividing the exercise price per share of our common stock at which your option was exercisable immediately prior to the effective time of the merger by the option ratio. If you hold an outstanding stock option that is assumed by Sun Microsystems, it will be vested immediately after the effective time of the merger in a percentage amount equal to the percentage of shares vested prior to the effective time, except to the extent that the terms of your option provides for acceleration of vesting upon the effective time.

If you are a director or consultant of ours or an employee who is not continuing with Sun Microsystems, you will receive cash representing the difference between $0.90 per share and the exercise price of your vested options.

See “The Merger—Effect on Awards Outstanding Under Tarantella’s Stock Plans.”

Following the effective time, under the merger agreement, if you hold an outstanding warrant to purchase our common stock, it will represent only the right, upon valid exercise thereof, if any, to receive the merger consideration payable for shares of our common stock previously issuable upon exercise of your warrant. We have agreed to use commercially reasonable efforts to have you either fully exercise your warrants prior to the effective time or to agree that your warrants will be terminated upon such time. If you hold a warrant that has been terminated, you will be entitled to receive upon surrender of the certificate representing your warrant an amount equal to the product of the number of shares of our common stock issuable upon exercise of your warrant multiplied by the excess, if any, of the per share merger consideration over the per share exercise price in effect for your warrant. See “The Merger—Warrants.”

Our common stock is quoted on the Over-the-Counter (“OTC”) Bulletin Board under the symbol “TTLA.OB”. On May 9, 2005, the last full trading day prior to the public announcement of the proposed merger, our common stock closed at $0.83. On June 9, 2005, the last full trading day prior to the date of this proxy statement, our common stock closed at $0.88. See “Market Price and Dividend Data.”

The exchange of shares of our common stock for the cash merger consideration will be a taxable transaction to our shareholders for United States federal income tax purposes. See “Material United States Federal Income Tax Consequences of the Merger.”

Tax matters can be complicated, and the tax consequences of the merger to you will depend on the facts of your own situation. We strongly urge you to consult your own tax adviser to fully understand the tax consequences of the merger to you.

Our board of directors approved the merger based on a number of positive factors, including the following:

In approving the merger, our board of directors also took into account a number of negative factors, including the following:

See “The Merger—Reasons for the Merger and Recommendation by the Board of Directors.”

Roth Capital Partners, LLC delivered its opinion to our board of directors on May 9, 2005 that, as of the date of the written opinion and based upon and subject to the various considerations set forth in that written opinion, the $0.90 per share in cash consideration to be received by holders of our common stock pursuant to the merger agreement is fair from a financial point of view to those holders of our common stock.

The full text of the written opinion of Roth Capital Partners, LLC, dated May 9, 2005, which sets forth the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion, is attached as Annex C to this proxy statement. Our shareholders should read the opinion in its entirety. Roth Capital Partners, LLC provided its opinion for the information and assistance of our board of directors in connection with its consideration of the transaction contemplated by the merger agreement. The Roth Capital Partners, LLC opinion is not a recommendation as to how any holder of our common stock should vote or act with respect to the transaction or any other matter.

Time, Date and Place. A special meeting of our shareholders will be held on July 6, 2005, at the Hyatt Regency San Francisco Airport, 1333 Bayshore Highway, Burlingame, California 94010, at 10:00 a.m., local time, to consider and vote upon a proposal to adopt the merger agreement and approve the principal terms of the merger.

Record Date and Voting Power. You are entitled to vote at the special meeting if you owned shares of our common stock at the close of business on June 8, 2005, the record date for the special meeting. You will have one vote at the special meeting for each share of our common stock you owned at the close of business on the record date. There are 27,994,937 shares of our common stock entitled to be voted at the special meeting.

Required Vote. The adoption of the merger agreement and approval of the principal terms of the merger requires the affirmative vote of a majority of the shares of our common stock outstanding at the close of business on the record date.

Share Ownership of Directors and Management. Our directors and executive officers and their affiliates own approximately 4.8% of the shares entitled to vote at the special meeting. All of our executive officers and directors have agreed with Sun Microsystems to, among other things, vote shares of our common stock in respect of which they have voting power or control in favor of the adoption and approval of the merger agreement.

See “The Special Meeting” and “The Merger Agreement and the Voting Agreements—The Voting Agreements.”

When considering the recommendation by our board of directors, you should be aware that a number of our officers and directors have interests in the merger that are different from yours, including, among others:

See “The Merger—Interests of Tarantella’s Directors and Management in the Merger.”

The parties’ obligations to effect the merger are subject to the satisfaction or waiver of various conditions, which include the following:

Sun Microsystems and we are obligated to effect the merger only if the following conditions are satisfied or waived:

Sun Microsystems will not be obligated to effect the merger unless the following conditions are satisfied or waived:

In addition, Sun Microsystems will not be obligated to complete the merger if there is a pending or threatened suit, action or proceeding asserted by any governmental entity:

We will not be obligated to effect the merger unless the following conditions are satisfied or waived:

See “The Merger Agreement and the Voting Agreement—The Merger Agreement—Conditions to Completion of the Merger.”

Sun Microsystems and we can terminate the merger agreement under certain circumstances, including:

See “The Merger Agreement and the Voting Agreement—The Merger Agreement—Termination.”

No Solicitation. We have agreed we will not, and will not permit any of our subsidiaries to, and we will use all reasonable efforts to cause our and our subsidiaries’ officers and directors, employees, agents and representatives including our or their investment bankers, attorneys, accountants or other representatives not to, directly or indirectly:

Superior Offers. Notwithstanding anything to the contrary described above, in the event we receive an unsolicited, bona fide written acquisition proposal from a third party to acquire all or substantially all of our assets or a majority of our total outstanding voting securities that our board of directors has in good faith concluded (following the receipt of the advice of outside legal counsel and our financial adviser) is, or is reasonably likely to result in, an offer that is more favorable from a financial point of view to our shareholders than the terms of the merger and is reasonably capable of being consummated, we may then take the following actions (only if and to the extent that our board of directors concludes in good faith, following the receipt of outside legal counsel, that the failure to do so is reasonably likely to result in a breach of its fiduciary obligations under applicable law):

See “The Merger Agreement and the Voting Agreement—The Merger Agreement—No Solicitation.”

The merger agreement provides that regardless of whether the merger is consummated, all fees and expenses incurred by the parties in connection with the merger will be borne by the party incurring such fees and expenses.

The merger agreement requires, however, that we pay Sun Microsystems a termination fee of $1,200,000 if, any of the following events occur:

See “The Merger Agreement and the Shareholders Agreement—The Merger Agreement—Termination Fee.”

All of our executive officers and directors have agreed with Sun Microsystems to, among other things, vote shares of our common stock in respect of which they have voting power or control in favor of the adoption and approval of the merger agreement. On June 8, 2005, these shareholders together owned and were entitled to vote 1,342,143 shares of our common stock, or approximately 4.8% of the outstanding shares of our common stock on that date.

See “The Merger Agreement and the Voting Agreements—The Voting Agreements.”

Pursuant to the terms of the merger agreement, we have entered into the First Amendment and Modification of the Sun Professional Services Blanket Purchase Agreement with Sun Microsystems effective as of May 20, 2005, which provides for the following:

See “The Merger Agreement and the Voting Agreements—The Licensing Agreement.”

The merger will be accounted for as a “purchase transaction” for financial accounting purposes. See “The Merger—Accounting Treatment.”

No filings are expected to be required to be made with the Antitrust Division of the Department of Justice and the Federal Trade Commission under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. The merger will be subject to review by the governmental authorities of Germany and may be subject to review by authorities in various other jurisdictions under the antitrust laws of those jurisdictions. See “The Merger—Regulatory Matters.”

Our shareholders who do not vote in favor of the merger will have 30 days from the date they are notified by us that the merger has been approved by our shareholders to exercise their dissenters’ rights with respect to the merger. Shareholders who validly exercise statutory dissenters’ rights to receive the fair market value of their shares in cash pursuant to applicable provisions of California corporate law will not have the right to receive that portion of consideration otherwise payable with respect to such shares after the effective time, but will instead be entitled to such statutory dissenters’ rights. A shareholder who does not timely perfect his or her dissenters’ rights will be deemed to have had his or her shares converted into the right to receive that portion of the consideration otherwise payable with respect to such shares after the effective time. See “The Merger—Dissenters’ Rights.”

Effective as of the opening of business on October 21, 2003, our common stock was de-listed from the Nasdaq Stock Market. Our common stock is now quoted on the OTC Bulletin Board under the symbol “TTLA.OB.” The following sets forth the high and low bid prices for each quarter during our last two fiscal years.

The following table sets forth the closing per share sales price of our common stock, as reported on the OTC Bulletin Board on May 9, 2005, the last full trading day before the public announcement of the proposed merger, and on June 9, 2005, the latest practicable trading day before the printing of this proxy statement:

We have never declared or paid cash dividends on our common stock. Our current policy is to retain future earnings, if any, for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. Following the merger there will be no further market for our common stock.

We are furnishing this proxy statement to our shareholders as part of the solicitation of proxies by our board of directors for use at the special meeting.

We will hold the special meeting at the Hyatt Regency San Francisco Airport, 1333 Bayshore Highway, Burlingame, California 94010 at 10:00 A.M., local time, on July 6, 2005.

At the special meeting, we will ask holders of our common stock to adopt the merger agreement and approve the principal terms of the merger. Our board of directors has unanimously approved and declared the merger, the merger agreement and the transactions contemplated by the merger agreement advisable, has unanimously declared that we enter into the merger agreement and consummate the merger on the terms and conditions set forth in the merger agreement and unanimously recommends that our shareholders vote FOR the adoption of the merger agreement.

Only holders of record of our common stock at the close of business on June 8, 2005, the record date, are entitled to notice of and to vote at the special meeting. On the record date, 27,994,937 shares of our common stock were issued and outstanding and held by approximately 493 holders of record. A quorum is present at the special meeting if a majority of the shares of our common stock issued and outstanding and entitled to vote on the record date are represented in person or by proxy. In the event that a quorum is not present at the special meeting, it is expected that the meeting will be adjourned or postponed to solicit additional proxies. Holders of record of our common stock on the record date are entitled to one vote per share at the special meeting on the proposal to adopt the merger agreement and approve the principal terms of the merger.

The adoption of the merger agreement and the principal terms of the merger requires the affirmative vote of the holders of a majority of the shares of our common stock outstanding and entitled to vote on the record date. If a Tarantella shareholder abstains from voting or does not vote, either in person or by proxy, it will count as a vote against the adoption of the merger agreement and approval of the principal terms of the merger.

At the close of business on the record date, our directors and executive officers and their affiliates owned and were entitled to vote 1,342,143 shares of our common stock, which represented approximately 4.8% of the shares of our common stock outstanding on that date.

Simultaneously with the execution and delivery of the merger agreement, all of our executive officers and directors entered into voting agreements with Sun Microsystems. On June 8, 2005, these shareholders together owned and were entitled to vote 1,342,143 shares of our common stock, or approximately 4.8% of the outstanding shares of our common stock on that date.

The shareholders signing the voting agreements agreed, among other things, to vote their shares of our common stock in favor of the adoption of the merger agreement and in favor of the merger and its principal terms and in favor of actions contemplated by the merger agreement and this proxy statement at any meeting of our shareholders at which such matters are considered and at every adjournment or postponement thereof. The shareholders signing the voting agreements also agreed to vote against any acquisition proposal or material change in the capitalization or corporate structure of us or our subsidiaries, or any other action that is intended or could reasonably be expected to impede, interfere with, delay, postpone, discourage or adversely affect the merger or any transactions contemplated by the merger agreement in any material respect. The shareholders signing the voting agreements granted a proxy and power of attorney with respect to any of our shares that they owned with respect to such matters to certain officers of Sun Microsystems.

Restrictions on Transfer and Other Voting Arrangements. The shareholders party to the voting agreements have agreed not to assign, sell, transfer, tender, pledge, hypothecate, give, place in trust, constructively sell or otherwise dispose of any of our shares subject to the voting agreement prior to the earlier of the effective time of the merger or the time the merger agreement is terminated pursuant to its terms. In addition, the shareholders have agreed not to deposit any shares or options in a voting trust or grant any proxy or enter into any voting agreement in contravention of his or her obligations under the Voting Agreements.

Termination. The voting agreements provide that they will terminate upon the earlier of the effective time of the merger and the time the merger agreement is terminated pursuant to its terms.

All shares represented by properly executed proxies received in time for the special meeting will be voted at the special meeting in the manner specified by the holders. Properly executed proxies that do not contain voting instructions will be voted “for” the adoption of the merger agreement and the approval of the merger.

Shares of our common stock represented at the special meeting but not voting, including shares of our common stock for which proxies have been received but for which shareholders have abstained, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business.

Only shares affirmatively voted for the adoption of the merger agreement and approval of the merger, including properly executed proxies that do not contain voting instructions, will be counted as favorable votes for that proposal. If a Tarantella shareholder abstains from voting or does not execute a proxy, it will effectively count as a vote against the adoption of the merger agreement and the approval of the merger. Brokers who hold shares of our common stock in street name for customers who are the beneficial owners of such shares may not give a proxy to vote those customers’ shares in the absence of specific instructions from those customers. These non-voted shares will effectively count as votes against the adoption of the merger agreement and the approval of the merger.

The persons named as proxies by a shareholder may propose and vote for one or more adjournments of the special meeting, including adjournments to permit further solicitations of proxies. No proxy voted against the proposal to adopt the merger agreement and approve the principal terms of the merger will be voted in favor of any such adjournment or postponement.

We do not expect that any matter other than the proposal to adopt the merger agreement and approve the principal terms of the merger will be brought before the special meeting. If, however, our board of directors properly presents other matters, the persons named as proxies will vote in accordance with their judgment as to matters that they believe to be in the best interests of the shareholders.

The grant of a proxy on the enclosed form of proxy does not preclude a shareholder from voting in person at the special meeting. A shareholder may revoke a proxy at any time prior to its exercise by:

If you have instructed your broker to vote your shares, you must follow directions received from your broker to change these instructions.

All costs of solicitation of proxies will be borne by us. We have retained Morrow & Co. to aid in the solicitation of proxies and to verify records relating to the solicitation. Morrow & Co. will receive customary fees of approximately $4,500 and expense reimbursement for these services. We estimate that approximately 15 employees of Morrow & Co. will be involved in the solicitation of proxies on our behalf. The extent to which these proxy soliciting efforts will be necessary depends entirely upon how promptly proxies are received. Also, proxies may be solicited by our directors, officers and regular employees, without additional compensation, personally or by telephone or by facsimile. You should send in your proxy by mail without delay. We also reimburse brokers and other custodians, nominees and fiduciaries for their expenses in sending these materials to you and getting your voting instructions.

Shareholders should not send stock certificates with their proxies. A letter of transmittal with instructions for the surrender of our common stock certificates will be mailed to our shareholders as soon as practicable after completion of the merger. The instructions will provide that, at the election of the shareholder, certificates may be surrendered, and the merger consideration in exchange for the certificates may be collected, by hand delivery.

The following discussion summarizes the material terms of the merger. Shareholders should read the merger agreement and the voting agreement, which are attached as Annexes A and B to this proxy statement.

In the course of evaluating the direction of our business, our management and board of directors have periodically considered various strategic alternatives to enhance our markets and customer opportunities, including possible acquisitions of complementary businesses, commercial partnering arrangements and strategic combinations with other companies.

Our board of directors consists of Alok Mohan, our Chairman of the Board, Francis E. Wilde, our President and Chief Executive Officer, Douglas Michels, our former Chief Executive Officer and consultant, and four non-employee directors.

On March 11, 2004, we entered into an agreement with Sun Microsystems, requiring the two companies to preserve the confidentiality of business information shared in connection with certain discussions. Later that month, Mr. Wilde met with a representative of Sun Microsystems to begin a major accounts program which would enable Sun Microsystems to adopt Tarantella products for OEM sales. Mr. Wilde and Theresa Murdock, our Director, Strategic Alliances, then attended the annual Sun Microsystems partner event in late April and met with William Cook, Vice President of U.S. Sales of Sun Microsystems. At that meeting, Mr. Wilde and Ms. Murdock discussed the possibility of an acquisition of Tarantella by Sun Microsystems.

In early May 2004, Mr. Wilde met with representatives of Sun Microsystems to further discuss Sun Microsystems’ interest in entering into an OEM agreement or other relationship with Tarantella. In the ensuing weeks, the companies had further discussions concerning an OEM relationship.

In the summer of 2004, Mr. Wilde contacted Page Mill Partners as a financial adviser for assistance in a review of possible acquisition opportunities as well as strategic alliance and partnering transactions. We entered into an engagement letter with Page Mill Partners dated as of August 26, 2004, for the purpose of securing Page Mill Partners’ advice regarding a possible business combination or sale of our business. The services initially provided by Page Mill Partners in August 2004 consisted principally of analyzing our business and markets, and, consistent with the stated interest of our board of directors, working with us to identify strategic partnering alternatives as well as possible acquisition candidates. Our financial adviser’s activities on our behalf in the fall of 2004 included informal inquiries of a number of potential merger partners to gauge their interest in a possible combination transaction with us. None of these inquiries resulted in any meaningful indication of interest from the contacted parties.

At the end of October 2004, Jon Williams, Director, Corporate Development, of Sun Microsystems, informed Mr. Wilde that Sun Microsystems might be interested in acquiring Tarantella. Shortly thereafter, the parties discussed possible strategies for integrating their product lines and Sun Microsystems conducted customer reviews of our installations. During the next few months, no discussions were held regarding a possible acquisition by Sun Microsystems.

On January 13, 2005, Brian Sutphin, Executive Vice President, Corporate Development, of Sun Microsystems, contacted Mr. Wilde to inform him that Sun Microsystems wished to discuss a possible acquisition of Tarantella. Later in January 2005, Mr. Wilde and other members of management engaged in a series of telephone calls and meetings with members of our board of directors to discuss Sun Microsystems’ expression of interest. During this period, Mr. Wilde and other members of management also engaged in discussions with representatives of Page Mill Partners regarding Sun Microsystems’ expression of interest. Formal informational updates of communications with Sun Microsystems’ representatives by our management were presented to our board of directors on January 20,

2005. The information presented at these meetings also included summaries by management of contacts conducted by our financial adviser with other potential merger partners.

Over the course of the ensuing several weeks, at the direction of our board of directors, Page Mill Partners continued to make informal inquiry of a number of prospective merger partners on our behalf, including renewed contacts with companies previously contacted by Page Mill Partners in the fall. None of these contacts resulted in any meaningful interest in acquiring our company. Mr. Wilde and John M. Greeley, our Vice President and Chief Financial Officer, also retained O’Melveny & Myers LLP to provide advice to Tarantella and its board of directors regarding the possible transaction with Sun Microsystems and the duties of the board of directors in connection with a possible acquisition transaction.

On February 1, 2005, we entered into an agreement with Roth Capital Partners, LLC to engage them for purposes of rendering an opinion as to the fairness from a financial point of view of any consideration to be paid to our shareholders in a change of control transaction.

Mr. Wilde and Brian Moriarty, Vice President of Business Affairs of Sun Microsystems, held a series of meetings between February 4 and February 8, 2005 to outline the set of circumstances surrounding an acquisition proposal by Sun Microsystems. On February 8, Sun Microsystems began discussing principal terms of a possible transaction with us through its counsel, Wilson, Sonsini, Goodrich & Rosati, and with Page Mill Partners and O’Melveny & Myers LLP.

On February 9, our board of directors convened in Santa Cruz, California with all members present. Mr. Greeley and Daniel M. Jochnowitz, our Acting General Counsel and Secretary, also attended. Mr. Wilde provided our board of directors with background on our discussions with Sun Microsystems and Sun Microsystems’ interest in acquiring us. Mr. Wilde also presented a summary of the key terms of the possible transaction discussed with Sun Microsystems. The board of directors engaged in a detailed discussion of those matters, and Mr. Wilde described the various other potential acquirors and the status of discussions with them. Mr. Wilde also identified various alternatives to a transaction with Sun Microsystems. After several hours of discussion, our board of directors decided that it was in the best interest of Tarantella’s shareholders to negotiate on an exclusive basis with Sun Microsystems and authorized our officers to negotiate a merger agreement, a voting agreement and any other agreements as necessary.

On February 10, Mr. Wilde called Mr. Moriarty to advise him that Tarantella was prepared to execute an agreement providing that Tarantella would negotiate on an exclusive basis with Sun Microsystems concerning a change of control transaction for a limited period of time and had authorized Sun Microsystems to begin a due diligence review of our business. We executed an agreement to negotiate exclusively with Sun Microsystems on February 11, 2005.

Beginning on February 18, 2005 and continuing through the beginning of March, representatives of Sun Microsystems conducted a due diligence review of our business and operations, including meetings and discussions between representatives of Sun Microsystems and members of our senior management and other selected employees, as well as a comprehensive document review. The meetings and discussions with our senior management and employees and related document review were intended to provide the representatives of Sun Microsystems with an understanding of the operational, financial, employee and legal aspects of our business.

On February 18, 2005, we received a draft merger agreement from Sun Microsystems’ legal counsel, Wilson, Sonsini, Goodrich & Rosati, and instructed our legal counsel, O’Melveny & Myers LLP, to begin reviewing and discussing the terms of the draft agreement with Sun Microsystems’ counsel. Our legal counsel communicated from time to time with Sun Microsystems’ legal counsel from February 19, 2005 until March 14, 2005 for the purpose of negotiating terms of the draft merger agreement and discussing related acquisition matters. During this period, representatives of Sun Microsystems continued to engage in a due diligence review of our company and its business.

During most of February and March, our management, consisting principally of Mr. Wilde, Mr. Greeley, Stephen Bannerman, our Chief Marketing Officer, and E. Joseph Vitetta, our Vice President, Corporate Development, and Managing Director of EMEA, and Sun Microsystems’ representatives engaged in regular telephone discussions. These discussions focused on the status of outstanding business issues relating to our operations and time schedules for resolution of these matters.

On the morning of March 2, 2005, our board of directors, with all members and our financial adviser and legal counsel present, convened by telephone conference call. Mr. Wilde updated our board of directors on the progress in negotiations with Sun Microsystems, noting that several key terms, including price, had not yet been determined. Mr. Wilde also noted that none of the other possible acquirors that had previously engaged in discussions with us had expressed any interest in entering into an agreement with us. Mr. Wilde described the role of Roth Capital Partners, LLC in rendering an opinion to the Board and described Roth Capital Partners, LLC’s experience with us and our industry. Representatives of Roth Capital Partners, LLC addressed questions from our directors about the process of preparing their fairness opinion and their methodologies. Our legal counsel reviewed the proposed transaction structure and the status of negotiations, including a discussion of the voting agreements and treatment of options that had been issued.

On the morning on Friday, March 11, 2005, our board of directors, with all members (other than Gilbert P. Williamson) and our financial adviser and legal counsel present, convened by telephone conference call to discuss the business meetings and the discussions between our management and business representatives of Sun Microsystems up to March 11, 2005. Mr. Wilde reviewed the discussions that had been held with Sun Microsystems regarding price. Representatives of Roth Capital Partners, LLC reviewed with our board the methodology for evaluating the fairness of the price that Sun Microsystems might offer if an agreement on price was achieved, and our legal counsel presented a detailed review of the draft merger agreement and reviewed the terms and conditions of the agreement, including remaining terms yet to be resolved. In the context of summarizing the provisions of the agreement, counsel also reviewed with the board members their fiduciary duties in connection with the proposed transaction. No conclusions or resolutions were reached by the board at this meeting. Mr. Wilde subsequently called Mr. Williamson to brief him on the matters discussed at the March 11, 2005 meeting.

Later that day, members of our executive management, as well as other senior management members, met with management representatives of Sun Microsystems in Santa Clara, California. This meeting addressed a broad range of business and operational matters. Representatives of Sun Microsystems also continued their due diligence review.

On March 14, 2005, Mr. Moriarty telephoned Mr. Wilde to inform him that Sun Microsystems had decided not to proceed with the transaction for a variety of reasons. In the ensuing days, Mr. Wilde discussed Sun Microsystems’ decision with Mr. Moriarty. Tarantella attempted to address the issues raised by Sun Microsystems.

In April, we began discussions with Sun Microsystems on a development agreement that would enable Sun Microsystems to commercialize our technology. We agreed to continue discussions on such a development agreement on April 7, 2005 in a meeting with Alan Brenner, Vice President, and other representatives of Sun Microsystems.

On May 4, 2005, Mr. Moriarty contacted Mr. Wilde to inform him that Sun Microsystems wanted to restart discussions concerning a merger with Tarantella instead of entering into a development agreement. On May 4 and May 5, Mr. Wilde held numerous discussions with board members, including Mr. Mohan, Mr. Ryan and Mr. Michaels, and our financial advisers. Mr. Wilde requested Page Mill Partners contact Mr. Moriarty to renew discussions regarding Tarantella’s valuation and to also solicit interest from other possible acquirors.

On the afternoon of Friday, May 6, 2005, Messrs. Wilde, Greeley and Vitetta along with Tarantella’s legal advisers from O’Melveny & Myers LLP met with Mr. Moriarty and others from Sun Microsystems and its legal

representatives from Wilson Sonsini Goodrich & Rosati at the headquarters of Sun Microsystems in Santa Clara to discuss the draft of the merger agreement from the discussions in March 2005. Both parties spent the weekend preparing and negotiating the merger agreement and the schedules to be attached to the merger agreement.

On the morning of May 9, 2005, following continued negotiations of the draft merger agreement between representatives of the two companies, our board of directors, with all members and our financial adviser and legal counsel present, convened by telephone conference call. During this meeting, counsel noted that all major issues under the merger agreement had been resolved subject to board approval and reviewed the proposed terms of the merger agreement and the fiduciary duties of the board of directors with respect to the merger. After discussion, our financial adviser delivered to our board their oral opinion, subsequently confirmed in writing, that, as of such date, the purchase price of $0.90 per share in cash consideration to be received by holders of our common stock, pursuant to the merger agreement, was fair from a financial point of view to the holders of our common stock. Our board of directors, with all members present and voting, then unanimously adopted resolutions approving the merger agreement, authorizing the transaction and recommending that our shareholders adopt and approve the merger agreement and approve the principal terms of the merger.

The merger agreement and related agreements for the acquisition were finalized and executed by the parties during the evening of May 9, 2005, and we and Sun Microsystems publicly announced the signing of a definitive agreement early in the morning of May 10, 2005.

Reasons for the Merger. In the course of reaching its decision to approve the merger and the merger agreement, our board of directors consulted with our senior management, financial adviser and legal counsel, reviewed a significant amount of information and considered a number of factors, including, among others, the following:

In the course of its deliberations, our board of directors also considered, among other things, the following positive factors:

In the course of its deliberations, our board of directors also considered, among other things, the following negative factors:

The preceding discussion of the information and factors considered by our board of directors is not, and is not intended to be, exhaustive. In light of the variety of factors considered in connection with its evaluation of the merger and the complexity of these matters, our board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative weights to the various factors considered in reaching its determination. In addition, our board of directors did not undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the ultimate determination of our board of directors, but rather, our board of directors conducted an overall analysis of the factors described above, including discussions with and questioning of our senior management and legal and financial advisers.

Board of Directors Recommendation. After careful consideration, our board of directors has unanimously approved and unanimously declared the merger, the merger agreement and the transactions contemplated by the merger agreement advisable, has unanimously declared that it is in the best interests of our shareholders that we enter into the merger agreement and consummate the merger on the terms and conditions set forth in the merger agreement and unanimously recommends that our shareholders vote FOR the adoption and approval of the merger agreement and approval of the principal terms of the merger.

We retained Roth Capital Partners, LLC (“Roth”) to act as our financial adviser in connection with the merger. In connection with Roth’s engagement, it evaluated the fairness, from a financial point of view, of the merger consideration to be received by the holders of our common stock. On May 9, 2005, our board of directors met to review the proposed merger and the terms of the merger agreement. During this meeting, Roth reviewed with our board of directors certain financial analyses, as described below, and rendered its oral opinion to our board of directors, subsequently confirmed in writing, that as of the date of its opinion and based upon and subject to the various considerations set forth in its opinion, the consideration to be received by holders of our common stock was fair from a financial point of view to those holders of common stock.

The full text of Roth’s opinion, which sets forth, among other things, assumptions made, matters considered and limitations on the scope of the review undertaken by Roth in rendering its opinion, is attached as Annex C to this proxy statement and is incorporated by reference in its entirety. You are urged to, and should, read the Roth opinion carefully and in its entirety. The Roth opinion addresses only the fairness, from a financial point of view, of the consideration to be received by our shareholders in the merger as of the date of its opinion. The fairness opinion was provided solely for the information of our board of directors, and may not be relied upon by any other person, used for any other purpose, or reproduced, disseminated, quoted or referred to at any time, in any manner or for any purpose without Roth’s prior written consent. The summary of the Roth opinion in this proxy statement is qualified in its entirety by reference to the full text of the Roth opinion.

Pursuant to an engagement letter dated February 1, 2005, we engaged Roth to render an opinion as to the fairness, from a financial point of view, of the consideration to be paid to our shareholders. Roth has provided certain investment banking and other services to us from time to time, including acting as a placement agent in a private placement transaction pursuant to which we sold common stock and warrants resulting in gross proceeds of approximately $16,350,000 on February 23, 2004. In connection with the proposed merger, Roth is not entitled to any fees which are contingent upon consummation of the proposed merger, but received a fee of $150,000 for delivery of its written opinion. In addition, the engagement letter provides that we will reimburse Roth for reasonable out-of-pocket expenses and indemnify it against certain liabilities arising out of its engagement. Roth is engaged by us to provide other advisory services which, if completed, may result in additional fees. In the ordinary course of Roth’s business, it may actively trade in our equity securities for its own account and for the accounts of its customers, and accordingly, may at any time hold a long or short position in our securities.

In connection with its review, Roth, with our consent, assumed and relied upon the accuracy and completeness of all financial and other information discussed with or provided to it by us or Sun Microsystems, or which is publicly available. Roth did not undertake any responsibility for the accuracy, completeness or reasonableness of, or to independently verify, such information. Roth further relied on the assurances of our management that it was not aware of any facts that would make any of the information reviewed by Roth inaccurate, incomplete or misleading in any respect.

With respect to forecasts regarding our future operating results that were provided to Roth, it assumed, without independent verification or investigation, that such forecasts were prepared on bases reflecting the best currently available information, estimates and judgments of our management and that the assumptions underlying such forecasts are reasonable. Roth was not engaged to assess the achievability of any projections or assumptions on which those forecasts were made, and it expresses no view as to those projections and assumptions. In addition, Roth did not assume any responsibility for any independent valuation or appraisal of our assets or liabilities, nor was it furnished with any such valuation or appraisal.

We have informed Roth, and it has assumed, that the proposed merger will be consummated in accordance with the terms set forth in the merger agreement which it reviewed and in compliance with the applicable provisions of the Securities Act, the Securities Exchange Act and all other applicable federal, state and local statutes, rules, regulations and ordinances.

Roth has assumed that the representations and warranties of each party in the draft of the merger agreement are true and correct, that each party will perform all covenants and agreements required to be performed by it under such agreement and that all conditions to the consummation of the proposed merger with Sun Microsystems will be satisfied without any waivers. Roth has further assumed that the final form of the merger agreement would be the same in all material respects (other than price) to the draft of the merger agreement dated as of March 11, 2005. In addition, Roth assumed that all governmental, regulatory and other consents and approvals contemplated by the merger agreement will be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions will be imposed or waivers made that would have an adverse effect on the contemplated benefits of the proposed merger with Sun Microsystems.

Roth was not requested to consider, and its opinion does not in any manner address, the relative merits of the proposed merger as compared to any alternative business strategies that might exist for us or the effects of any other transaction in which we might engage. Roth’s opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to it on or prior to, May 9, 2005. Although subsequent developments may affect its opinion, Roth does not have any obligation to update, revise or reaffirm its opinion and it expressly disclaims any responsibility to do so.

In furnishing its opinion, Roth does not admit that it is an expert within the meaning of the term “expert” as used in the Securities Act and the rules and regulations thereunder, nor does it admit that its opinion constitutes a report or valuation within the meaning of Section 11 of the Securities Act.

Roth did not attempt to combine the analyses described below into one composite valuation range, nor did Roth assign any quantitative weight to any of the analyses or the other factors considered. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to summary description. Furthermore, in arriving at its opinion, Roth did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor in light of one another. Accordingly, Roth has stated that it believes that its analyses must be considered as a whole and that considering any portion of its analyses, without considering all of the analyses, could create a misleading or incomplete view of the process underlying its opinion.

The following summaries of Roth’s financial analyses present some information in tabular format. However, the tables do not constitute a complete description of the financial analyses. In order to fully understand the financial analyses used by Roth, the tables must be read together with the related summary text and considered together as a whole. Considering any portion of such analyses and the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Roth’s opinion.

In connection with preparation and delivery of its opinion, Roth noted the sale process as well as performed five financial analyses, each of which resulted in an implied per share value range for Tarantella’s common stock as shown in the following table:

Comparable Public Company Analysis. This analysis is designed to derive a value range, at a given point in time, by a relative comparison of the stock trading price of publicly traded companies deemed similar to Tarantella. For purposes of making this comparison, Roth selected the following companies:

These companies were selected based upon, among other things, the following main criteria: type of business, size, growth, and profitability. Roth’s qualitative and quantitative assessment of Tarantella and the comparable companies includes historical financial performance, expected future performance and other investment considerations such as size and specific business risks. Roth calculated the enterprise value relative to trailing twelve months (TTM) and forecasted 2005 sales for each comparable public company. “Enterprise Value” is calculated as the sum of the value of the common equity on a fully diluted basis and the market value of any debt less cash, plus any minority interest and preferred stock. Roth assumed that a reasonable range of multiples to apply to Tarantella’s TTM and 2005 forecasted sales equaled the comparable public companies mean multiples for each of these periods, plus or minus one-half the standard deviation. Roth’s comparable public company analysis produced the following implied valuation ranges:

Roth noted that the merger consideration of $0.90 per share was within the implied valuation range per share of $1.25 and $0.63. Furthermore, Roth noted that none of the comparable public companies were identical to Tarantella and that, accordingly, any analysis of the comparable public companies involved complex considerations and judgments concerning differences in industry and individual company dynamics, financial and operating characteristics and various other factors that would necessarily affect the transaction multiples in the merger as compared to the multiples for the comparable companies.

Comparable Transactions Analysis. This analysis involves a review of the valuations reflected in acquisition transactions, whether through merger, stock purchase or asset purchase. Roth looked for completed transactions over the five year period ended May 6, 2005 where the target’s business was similar to that of Tarantella’s and was a domestic corporation. Furthermore, Roth only looked for those transactions where the targets’ TTM sales at the date of announcement were between $10 million and $110 million. Based on Roth’s search criteria, Roth selected the following 13 transactions:

Roth then calculated the enterprise value for each target relative to its TTM sales at the announcement date and assumed that a reasonable range of multiples to apply to Tarantella’s TTM sales equals the comparable transactions mean enterprise value to TTM sales multiple, plus or minus one-half the standard deviation. Roth’s comparable transaction analysis produced the following implied valuation ranges:

Roth noted that the merger consideration of $0.90 per share was within the implied valuation range per share of $1.24 and $0.63 calculated under the comparable transaction analysis. Furthermore, Roth noted that none of the comparable transactions were identical to the acquisition of Tarantella and that, accordingly, any analysis of the comparable transactions involved complex considerations and judgments concerning differences in industry and individual company dynamics, financial and operating characteristics and various other factors that would necessarily affect the transaction multiples in the merger as compared to the multiples for the comparable transactions.

Capitalization of Earnings Analysis. Management only provided Roth with two sets of condensed income statements for the fiscal year ending September 30, 2005, including a plan with revenues of $18.3 million and a net loss of $2.3 million and an “Upside Plan”, depicting Tarantella achieving revenues of $25.6 million and net income of $5.0 million for the fiscal year ending September 30, 2005. Generally, the Discounted Cash Flow Analysis is recognized to be the best method to use but usually requires at least five years of forecasted financial statements which include an income statement, balance sheet, and statement of cash flows. The Capitalization of Earnings or Cash Flows uses a single period’s historical normalized debt free net cash flows (“DFNCF”) and

divides it by a capitalization rate which is a calculated discount rate, less an appropriate growth rate. Usually, historical earnings or DFNCF are either averaged or weighted for the five previous years in order to calculate a single period’s DFNCF to capitalize. Roth noted that Tarantella has not generated cash from operations since its fiscal year ended September 30, 1999. Therefore, Roth took a conservative approach and used our “Upside Plan” for the fiscal year ending September 30, 2005 to derive a single period’s DFNCF. Since management did not provide Roth with a balance sheet or statement of cash flows for this period, Roth made certain assumptions about taxes, changes in working capital, and capital expenditures through discussions with management. As such, Roth calculated $3.8 million as DFNCF to capitalize. A capitalization rate of 18.9% was calculated based on an after-tax discount rate of 28.9%, derived from the select comparable public companies weighted-average cost of capital (“WACC”) and an appropriate size premium, less a 10% growth rate, to arrive at an estimated enterprise value of $19.8 million.

Roth also showed the relationship between the capitalization of earnings analysis and a discounted cash flow analysis. Had we provided Roth with forecasted DFNCF of $3.8 million for 2005 and grown that by ten percent over the next four years, they would have derived the same enterprise value of $19.8 million using the Discounted Cash Flow Analysis that they calculated under the Capitalization of Earnings Analysis which is shown below:

Roth performed a sensitivity analysis on the capitalization of earnings analysis by applying a various range of discount rates less growth rates to the estimated DFNCF for 2005. The growth estimates for DFNCF used ranged from 2.0% to 16.0%. Based on the foregoing ranges of DFNCF growth estimates and discount rates, the sensitivity analysis indicated a range of enterprise values as follows:

Roth shaded the enterprise values in the innermost quadrant of the sensitivity analysis and assumed a reasonable range of enterprise values for Tarantella equaled the mean multiple of these shaded enterprise values, plus or minus one-half the standard deviation. This produced a range of enterprise values and implied per share values for Tarantella’s common stock as shown below:

Roth noted that the merger consideration of $0.90 per share was above the implied valuation range per share of $0.82 and $0.70 calculated under the capitalization of earnings analysis.

Takeover Premium Analysis. In this analysis, Roth compared the takeover premium over the market trading price of the Company’s common stock offered to stockholders in the merger to the premiums or discounts paid for the 13 targets Roth analyzed in the Comparable Transactions Analysis (“Takeover Premium Analysis 1”). Furthermore, Roth also looked at premiums and or discounts paid in the market as a whole over the last two years where 100% of the target was acquired and cash was the form of consideration. The latter analysis resulted in 194 transactions (“Takeover Premium Analysis 2”).

Roth calculated the mean of the premiums paid in both analyses and assumed that a reasonable market range of takeover premiums equaled the mean plus or minus one-half the standard deviation. Using this range, Roth derived implied minimum and maximum per share market values for Tarantella’s common stock. These two analyses are depicted in the following tables:

Roth noted that the merger consideration of $0.90 per share was below the implied valuation range per share of $1.54 and $1.01 calculated under the takeover premium analysis.

Historical Share Price Analysis. On May 6, 2005, the closing price of Tarantella’s common stock was $0.77 per share. Roth calculated the premium of the $0.90 cash consideration as compared to Tarantella’s closing price, as well as compared Tarantella’s share price during the 52-week period prior to the announcement of the merger as shown in the following table:

In considering the recommendation of our board of directors in favor of the merger, you should be aware that members of our board of directors and certain of our officers and employees have interests in the merger that are different from, or in addition to, the interests of our shareholders.

These interests are described below, to the extent material, and except as described below, such persons have, to our knowledge, no material interest in the merger apart from those of our shareholders generally. Our board of directors was aware of, and considered the interests of, our directors, officers and employees in approving the merger agreement and the merger.

Change in Control Agreements with Our Directors. Pursuant to change of control agreements with directors Douglas Michels, Ninian Eadie, Bruce Lachman, Gilbert Williamson and Bruce Ryan entered into in February 2005, all stock options and restricted stock held by each of those directors will fully vest immediately prior to a change in control of Tarantella. A “change of control” is defined in the agreements to include, among other things, the occurrence of any person, directly or indirectly, becoming the beneficial owner of securities representing 50% or more of the combined voting power of our then outstanding securities entitled to vote generally in the election of directors, or the merger or consolidation of us with any other corporation, other than a merger or consolidation which would result in our voting securities outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least 50% of the total voting power represented by our voting securities or such surviving entity outstanding immediately after such merger or consolidation. Messrs. Michels, Eadie, Lachman, Williamson and Ryan each hold 388,349, 129,597, 89,200, 125,397 and 23,625 options, respectively, of which 68,891 in-the-money options held by Mr. Michels may be cashed out at the effective time for $31,450.95. Messrs. Eadie, Lachman, Williamson and Ryan do not hold any in-the-money options. Messrs. Michels, Lachman and Ryan each hold 16,447 shares of unvested restricted stock awarded in lieu of compensation that will fully vest as paid-in-full at the effective time and may be cashed out at that time for $14,802.30.

Amendments to a Change in Control Agreement with Francis E. Wilde. On February 11, 2005, we entered into an amendment to a change in control agreement with Mr. Wilde dated as of March 16, 2004. Pursuant to the amendment, if Mr. Wilde is involuntarily terminated in connection with a change in control, he is entitled to receive a termination payment. Under the terms of the merger agreement, however, all employees with benefits triggered in whole or in part by a change in control will be entitled to such benefits upon the closing regardless of any termination provisions in the agreements. Therefore, if there is a change in control as defined above for an amount equal to or less than $48 million, Mr. Wilde will be entitled to receive a payment equal to 12 times his total monthly compensation including targeted bonuses at 100% attainment. In addition, all stock options granted to Mr. Wilde will vest and become fully exercisable upon the closing of the merger. If that payment constitutes a “parachute payment” within the meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as

amended, and would result in all or a portion of the payment being subject to excise tax under the Internal Revenue Code, then Mr. Wilde would receive a lesser payment so that no portion of the payment would be subject to the excise tax. Mr. Wilde and his dependents will also be entitled to continue to be eligible to participate in health benefit plans on the same terms and conditions as in effect prior to the change in control for up to 12 months. Under the amendment, Mr. Wilde will be entitled to receive cash in the amount of $225,000 in addition to an estimated $15,600 for health care. Mr. Wilde holds 475,000 options, of which unvested options to purchase 394,375 shares will accelerate and vest in full at the effective time. None of those options are in-the-money.

Change in Control Agreements with John M. Greeley, Stephen Bannerman and E. Joseph Vitetta, Jr. On February 11, 2005, we entered into amendments to change in control agreements with each of Messrs. Greeley, Bannerman and Vitetta dated as of March 16, 2004. Pursuant to the agreements, if either Mr. Greeley, Mr. Bannerman or Mr. Vitetta, respectively, is involuntarily terminated in connection with a change in control, he is entitled to receive a termination payment. Under the terms of the merger agreement, however, all employees with benefits triggered in whole or in part by a change in control will be entitled to such benefits upon the closing regardless of any termination provisions in the agreements. Therefore, if there is a change in control as defined above for an amount equal to or less than $48 million, each of Messrs. Greeley, Bannerman and Vitetta will be entitled to receive a payment equal to 12 times his total monthly compensation including targeted bonuses at 100% attainment. In addition, all stock options granted to each of Messrs. Greeley, Bannerman and Vitetta will vest and become fully exercisable upon the closing of the merger. If that payment constitutes a “parachute payment” within the meaning of Section 280G(b)(2) of the Internal Revenue Code of 1986, as amended, and would result in all or a portion of the payment being subject to excise tax under the Internal Revenue Code, then each of Messrs. Greeley, Bannerman and Vitetta would receive a lesser payment so that no portion of the payment would be subject to the excise tax. Each of Messrs. Greeley, Bannerman and Vitetta and their dependents will also be entitled to continue to be eligible to participate in health benefit plans on the same terms and conditions as in effect prior to the change in control for up to 12 months. Under their respective agreements, Messrs. Greeley, Bannerman and Vitetta will be entitled to receive cash in the amounts of $300,000, $315,000 and $366,000, respectively, in addition to an estimated $15,600, $16,800, and $16,800, respectively, for health care. Messrs. Greeley, Bannerman and Vitetta hold 347,500, 145,000 and 222,500 options, respectively, of which unvested options to purchase 278,125, 118,500 and 186,250 shares, respectively, will accelerate and vest in full at the effective time. None of those options are in-the-money.

Change in Control Agreement with Alok Mohan. We entered into a change in control agreement with Mr. Mohan dated as of February 11, 2005. Under this agreement, if there is a change in control as defined above for an amount equal to or less than $48 million, Mr. Mohan’s change in control payment will be equal to the aggregate of (i) the target incentive payment contemplated under his 2005 Consulting Agreement on the basis of 100% attainment and (ii) one times the annual compensation contemplated under his 2005 Consulting Agreement in an amount of $90,000 payable in cash, as adjusted to reflect any amounts and stock (based on the original value of the stock on the date of grant) already earned under the 2005 Consulting Agreement to ensure that Mr. Mohan receives a payment equal to two full year’s annual compensation. In addition, all stock options and restricted stock granted to Mr. Mohan will vest and become fully exercisable immediately prior to the change in control. Under his change in control agreement, Mr. Mohan will receive approximately $150,000 in cash although the actual amount of cash compensation that Mr. Mohan will receive will depend on the amount of unearned restricted stock under his Consulting Agreement that was accelerated at the effective time. The value of this accelerated, unearned restricted stock (based on the original value of the stock on the date of grant) is deducted from the cash payable for the annual compensation component of $90,000. Mr. Mohan will also receive an estimated $20,400 for health care. Mr. Mohan holds 373,603 options and 75,658 shares of unvested restricted stock awards of which 16,447 shares relate to deferred director compensation and 59,211 shares relate to deferred consulting compensation. Mr. Mohan’s unvested options to purchase 142,750 shares will accelerate and vest in full at the effective time, of which 21,600 options are in-the-money and may be cashed out at the effective time for $9,720. The unvested restricted stock awards will fully vest as paid-in-full at the effective time and may be cashed out at that time for $68,092.20.

Change in Control Agreements with Certain Other Employees. Pursuant to change in control agreements with certain of our employees, each such employee will be eligible to receive any benefits triggered by a change in control of Tarantella upon the closing of the merger. All of our employees who are directors and non-executive officers are also entitled to certain change in control benefits. These benefits vary depending on title, but range from six to twelve months of severance based on current base salary plus target incentives on the basis of 100% attainment. In addition, these employees are entitled to certain payments in lieu of health care benefits for a period consistent with their severance payments. Any unvested options will also vest and become fully exercisable.

Indemnification and Insurance. The merger agreement provides that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the effective time of the merger (and rights for advancement of expenses) now existing in favor of our current and former directors or officers as provided in our articles of incorporation or by-laws and any indemnification agreements between us and our directors and officers in effect immediately prior to the effective time of the merger will be assumed by the surviving corporation in the merger without any further action by Sun Microsystems, Cha Cha Acquisition Corporation or us. Sun Microsystems will and will cause the surviving corporation to fulfill and honor those obligations. The articles of incorporation and by-laws of the surviving corporation will contain provisions with respect to exculpation and indemnification that are at least as favorable to our current and former directors and officers as those presently in effect. The merger agreement further provides that for six years after the effective time of the merger, Sun Microsystems will use best efforts to cause the surviving corporation to maintain directors’ and officers’ liability insurance for events occurring prior to the effective time of the merger covering those persons who were, as of the date of the merger agreement, covered by our directors’ and officers’ liability insurance policies, on terms comparable to those in effect on the date of the merger agreement. Sun Microsystems’ obligation to provide this insurance coverage is subject to a cap of 150% of the current annual premium paid by us for our existing insurance coverage. If Sun Microsystems cannot maintain the existing or equivalent insurance coverage without exceeding the 150% cap, Sun Microsystems is required to maintain as much insurance coverage as can be obtained by paying an annual premium equal to the 150% cap.

Stock Options. Under the merger agreement, at the effective time of the merger, each then outstanding employee stock option held by an employee who is continuing with Sun Microsystems, whether or not exercisable at the effective time of the merger and regardless of the exercise price, will be assumed by Sun Microsystems and will continue to have and be subject to the same terms and conditions set forth in the applicable option. However, each such outstanding employee stock option will be exercisable for that number of shares of Sun Microsystems’ common stock equal to the product of the number of shares of our common stock issuable upon exercise of such option multiplied by the option ratio, which is the ratio of the value of the per share merger consideration over the average of the closing prices for a share of Sun Microsystems’ common stock on the ten trading days prior to the closing date. The per share exercise price for the shares of Sun Microsystems’ common stock issuable upon exercise of the assumed employee stock options will be equal to the amount determined by dividing the exercise price per share of our common stock at which the option was exercisable immediately prior to the effective time of the merger by the option ratio. Prior to the effective time, each of our employee stock purchase plans will be terminated. Each employee stock option that is assumed by Sun Microsystems will be vested immediately after the effective time of the merger in a percentage amount equal to the percentage of shares vested prior to the effective time, except to the extent that the terms of the option provides for acceleration of vesting upon the effective time. See “The Merger—Effect on Awards Outstanding Under Tarantella’s Stock Plans.”

The 2003 Directors Stock Option Plan, which was originally adopted by our board of directors in March 1993 and approved by our shareholders in May 1993, provides that immediately prior to the occurrence of a change in control, as defined above, any options outstanding on the date such change in control is determined to have occurred that are not yet exercisable and vested on such date will become fully exercisable and vested. Under the change in control agreements discussed above, all stock options and restricted stock granted to our directors and executive officers will accelerate and vest in full immediately prior to a change in control of

Tarantella and they will receive cash representing the difference between $0.90 per share and the exercise price of their vested options in the amounts described above.

Employment Agreements. It is not currently anticipated that any of our current executive officers will be employed by Sun Microsystems after the merger is completed.

The discussion of the provisions set forth below is not a complete summary regarding your dissenters’ rights under California law and is qualified in its entirety by reference to the text of the relevant provisions of California law, which are attached to this proxy statement as Annex D. Shareholders intending to exercise dissenters’ rights should carefully review Annex D. Failure to follow precisely any of the statutory procedures set forth in Annex D may result in a termination or waiver of these rights.

Under Chapter 13 of the California General Corporation Law, certain holders of our stock may, by complying with the provisions of Chapter 13 and in lieu of receiving the cash consideration provided for in the merger, obtain cash for any shares that were not voted in favor of the merger at the fair market value of such shares. In general, a shareholder of a company electing to exercise dissenters’ rights must satisfy each of the following requirements set forth in Chapter 13: (i) the dissenting shareholder must not have voted in favor of the merger, (ii) the dissenting shareholder must make a written demand to have the company purchase the dissenting shares for cash at their fair market value, which demand must be received by the company not later than the date which is 30 days after the date of mailing of notice of the approval of the merger (voting against the merger does not constitute a demand), and (iii) the dissenting shareholder must submit the certificates representing the dissenting shares to the company at its principal office to be stamped or endorsed with a statement that the shares are dissenting shares.

A shareholder wishing to exercise dissenters’ rights must deliver to us a demand that satisfies the following requirements: (i) the demand must be made by the person who was the shareholder of record on the record date (or his or her duly authorized representative), and not by someone who is merely a beneficial owner of the shares and not by a shareholder who acquired the shares subsequent to the record date, (ii) the demand must state the number and class of shares held of record by such shareholder making the demand, and (iii) the demand must include a demand that we purchase the shares at what such shareholder claims to be the fair market value of the shares on the day before the terms of the merger were first announced, excluding any appreciation or depreciation because of the proposed merger. A shareholder may take the position in the written demand that a different date is applicable. The shareholder’s statement of fair market value constitutes an offer by such dissenting shareholder to sell the dissenting shares to us at such price.

In addition, the following conditions should be complied with to ensure that the demand is properly executed and delivered: (i) the demand should be sent by registered or certified mail, return receipt requested, (ii) the demand should be accompanied by the certificates representing the dissenting shares, (iii) the demand should be signed by the shareholder of record (or his or her duly authorized representative) exactly as his or her name appears on the certificate(s) evidencing the dissenting shares (a demand for the purchase of shares owned jointly by more than one person should identify and be signed by all such holders), and (iv) any person signing a demand for purchase in any representative capacity (such as attorney-in-fact, executor, administrator, trustee or guardian) should indicate his or her title and, if we so request, furnish written proof of his or her capacity and authority to sign the demand.

A shareholder may not withdraw a demand for payment without our consent. For purposes of exercising dissenters’ rights with respect to the merger, a demand by a shareholder will not be effective for any purpose unless it is received by us (or our transfer agent) by the date that is 30 days after the date of mailing of notice of the approval of the merger.

If we and a dissenting shareholder agree that the shares so held are eligible for dissenters’ rights and agree upon the price of such shares, the dissenting shareholder is entitled to receive from us the agreed price, with interest thereon from the date of such agreement calculated at the legal rate. Any agreement fixing the fair market value of dissenting shares as between us and the holders thereof must be filed with our company secretary. Subject to certain provisions of Section 1303 and Section 1306 of the California General Corporation Law, payment of the fair market value of the dissenting shares shall be made within 30 days after the amount thereof has been agreed upon or within 30 days after the statutory or contractual conditions to the merger are satisfied, whichever is later.

If we and a dissenting shareholder fail to agree on either the fair market value of the shares or on the eligibility of the shares to be purchased, then either the shareholder or any interested corporation may file a complaint for judicial resolution of the dispute in the California Superior Court of the proper county. The complaint must be filed within six months after the date on which the notice of approval of the merger was mailed to the shareholders. If a complaint is not filed within six months, the shares will lose their status as dissenting shares. Two or more dissenting shareholders may join as plaintiffs or be joined as defendants in such an action. If the eligibility of the shares as dissenting shares is at issue, the court will first decide this issue. If the fair market value of the shares is in dispute, the court will determine, or shall appoint one or more impartial appraisers to assist in its determination of, the fair market value. The costs of the action will be assessed or apportioned as the court considers equitable. If the appraised value exceeds the price offered by us, we must pay the costs. If the appraised value exceeds 125% of the price offered by us, such costs may include, at the court’s discretion, attorneys’ fees, fees of expert witnesses and interest calculated at the legal rate.

Written demands, notices or other communications which a shareholder wishes to send to us concerning the exercise of dissenters’ or appraisal rights should be addressed to Secretary, 100 Albright Way, Suite D, Los Gatos, California, 95032.

Failure by any Tarantella shareholder to comply fully with the procedures described above and set forth in Annex D to this proxy statement may result in termination of such shareholder’s appraisal rights. Those wishing to dissent should consult with their own legal counsel in connection with compliance under chapter 1300 of the California General Corporation Law.

The merger will be accounted for as a “purchase transaction” for financial accounting purposes.

Subject to the terms and conditions of the merger agreement and in accordance with California law, at the effective time of the merger, Cha Cha Acquisition Corporation, a wholly owned subsidiary of Sun Microsystems and a party to the merger agreement, will merge with and into us. We will survive the merger as a wholly owned California subsidiary of Sun Microsystems.

At the effective time of the merger, each outstanding share of our common stock, other than treasury shares, shares held by Sun Microsystems, shares held by a subsidiary of Sun Microsystems or us, and shares held by shareholders who perfect their appraisal rights (as described in “The Merger—Dissenters’ Rights”), will be canceled and extinguished and automatically converted into the right to receive $0.90 in cash, without interest, upon surrender of the certificate representing such share(s) of our common stock. Treasury shares and shares held by Sun Microsystems or Cha Cha Acquisition Corporation will be canceled immediately prior to the effective time of the merger. The price of $0.90 per share was determined through arm’s-length negotiations between Sun Microsystems and us.

The conversion of our common stock into the right to receive $0.90 per share in cash, without interest, will occur automatically at the effective time of the merger. As soon as reasonably practicable after the effective time of the merger, EquiServe Trust Company, the paying agent, will send a letter of transmittal to each holder of a certificate which represented outstanding shares of Tarantella or warrants to purchase our common stock. The letter of transmittal will contain instructions for obtaining cash in exchange for shares of our common stock or warrants to purchase our common stock. You should not return stock certificates with the enclosed proxy.

Upon surrender of a stock certificate representing shares of our common stock or a warrant to purchase our common stock, together with a duly completed and validly executed letter of transmittal, and any other documents that may be reasonably required by the paying agent, the holder of the certificate will be entitled to receive from the paying agent, on behalf of Sun Microsystems, as promptly as practicable in accordance with the paying agent’s customary procedures, (i) $0.90 in cash for each share represented by the stock certificate, and (ii) an amount for each warrant equal to the product of the number of shares of our common stock issuable upon exercise of the warrant multiplied by the excess, if any, of the per share merger consideration over the per share exercise price in effect for the warrant. The stock certificates and warrants will then be cancelled.

Until surrendered, any outstanding stock certificates or warrants will be deemed from and after the effective time of the merger to evidence ownership of (i) cash equal to $0.90 per share in the case of shares represented by stock certificates, or (ii) the excess of $0.90 per share over the per share exercise price in effect for the warrants.

Stock Options. Under the merger agreement, at the effective time of the merger, each then outstanding employee stock option held by an employee who is continuing with Sun Microsystems, whether or not exercisable at the effective time of the merger and regardless of the exercise price, will be assumed by Sun Microsystems and will continue to have and be subject to the same terms and conditions set forth in the applicable option. However, each such outstanding employee stock option will be exercisable for that number of shares of Sun Microsystems’ common stock equal to the product of the number of shares of our common stock issuable upon exercise of such option multiplied by the option ratio, which is the ratio of the value of the per share merger consideration over the average of the closing prices for a share of Sun Microsystems’ common stock on the ten trading days prior to the closing date. The per share exercise price for the shares of Sun Microsystems’ common stock issuable upon exercise of the assumed employee stock options will be equal to the amount determined by dividing the exercise price per share of our common stock at which the option was exercisable immediately prior to the effective time of the merger by the option ratio. Each employee stock option that is assumed by Sun Microsystems will be vested immediately after the effective time of the merger in a percentage amount equal to the percentage of shares vested prior to the effective time, except to the extent that the terms of the option provides for acceleration of vesting upon the effective time.

Our directors, consultants, and employees who are not continuing with Sun Microsystems will receive cash representing the difference between $0.90 per share and the exercise price of their vested options.

Sun Microsystems has agreed to file with the Securities and Exchange Commission a registration statement on Form S-8 for the shares of Sun Microsystems’ common stock issuable with respect to assumed options of continuing employees to the extent Form S-8 is available within 60 days after the effective time of the merger.

Employee Stock Purchase Plans. Under the merger agreement, each of our employee stock purchase plans must be terminated prior to the effective time of the merger. The rights of the participants in each of our employee stock purchase plans with respect to any offering period underway will be determined by treating the last business day prior to, or if more administratively advisable, our last payroll date prior to the effective time of

the merger, as the last day of such offering period but otherwise treating the shortened offering period as fully effective for all purposes under the plans.

Following the effective time, under the merger agreement, all outstanding warrants to purchase our common stock will represent only the right, upon valid exercise thereof, if any, to receive the merger consideration payable upon shares of our common stock previously issuable upon exercise of such warrants. We have agreed to use commercially reasonable efforts to have all holders of our warrants to either fully exercise such warrants prior to the effective time or agree that the warrants will be terminated upon such time, provided that the holder of a warrant that has been terminated will be entitled to receive upon surrender of the certificate representing a warrant an amount equal to the product of the number of shares of our common stock issuable upon exercise of the warrant multiplied by the excess, if any, of the per share merger consideration over the per share exercise price in effect for the warrant.

The merger will become effective upon the filing of an agreement of merger with accompanying officers’ certificates with the California Secretary of State or at such later time as is agreed upon by Sun Microsystems and us and specified in the certificate of merger. The filing of the certificate of merger will occur as soon as practicable on or after the closing date, which will not be later than the second business day after satisfaction or waiver of the conditions to the completion of the merger described in the merger agreement, provided that the closing date will not occur on a date that is during the last 15 business days prior to the last business day of a fiscal quarter of Sun Microsystems.

If the merger is completed, our common stock will no longer be quoted on the OTC Bulletin Board and will be deregistered under the Securities Exchange Act of 1934.

This Section discusses the material United States federal income tax consequences of the merger to our shareholders whose shares of our common stock are surrendered in the merger in exchange for the right to receive cash consideration of $0.90 per share or who receive cash in respect of dissenting shares of our common stock. The discussion below applies only to our shareholders that hold our common stock as capital assets at the time of the merger, and the discussion may not apply to:

The discussion below is based upon the United States federal income tax laws as in effect and interpreted as of the date of this proxy statement and does not take into account possible changes in these tax laws or interpretations, any of which may be applied retroactively. The discussion does not include any description of the tax laws of any state, local or foreign government that may be applicable to our shareholders.

The exchange of shares of our common stock for cash merger consideration in the merger or pursuant to the exercise of appraisal rights will be a taxable transaction for United States federal income tax purposes. A holder of our common stock generally will recognize capital gain or capital loss equal to the difference, if any, between the amount of cash received by the shareholder pursuant to the merger or in respect of a dissenting share, as the case may be, and the shareholder’s adjusted tax basis in the shares of our common stock surrendered. Gain or loss will be calculated separately for each block of shares exchanged in the merger or surrendered pursuant to the exercise of appraisal rights, as the case may be (i.e., shares acquired at the same cost in a single transaction). If at the time of the merger a non-corporate shareholder’s holding period for the shares of our common stock is more than one year, any gain recognized generally will be subject to United States federal income tax at a maximum rate of 15%. If the non-corporate shareholder’s holding period for the shares of common stock is one year or less at the time of the merger, any gain will be subject to United States federal income tax at the same graduated rates as ordinary income. The deductibility of capital losses is subject to limitations.

For corporations, capital gain is taxed at the same rate as ordinary income, and the use of capital losses is subject to limitations.

The cash consideration received by our non-corporate shareholders in the merger or in respect of a dissenting share of our common stock, as the case may be, may be subject to backup withholding at a 28% rate. Backup withholding generally will apply only if the shareholder fails to furnish a correct social security number or other taxpayer identification number, or otherwise fails to comply with applicable backup withholding rules and certification requirements. Corporations generally are exempt from backup withholding. Each non-corporate shareholder should complete and sign the substitute Form W-9 that will be part of the letter of transmittal to be returned to the paying agent in order to provide the information and certification necessary to avoid backup withholding, unless an applicable exemption exists and is otherwise proved in a manner satisfactory to the paying agent.

Any amounts withheld under the backup withholding rules will be allowed as a credit against the shareholder’s United States federal income tax liability and may entitle the shareholder to a refund, provided the shareholder furnishes specified required information to the Internal Revenue Service.

The foregoing does not purport to be a complete analysis of the potential tax consideration relating to the merger, and is not tax advice. Therefore, holders of our common stock are strongly urged to consult their tax advisers as to the specific tax consequences to them of the merger, including the applicability and effect of United States federal, state, local and foreign income and other tax laws in their particular circumstances.

Both Sun Microsystems and we are required to file pre-merger notifications with the German Federal Cartel Office. We cannot complete the merger prior to clearance by the German Federal Cartel Office. While we expect to receive the regulatory approval from the German Federal Cartel Office, we cannot assure you that we will receive it in a timely manner or at all. If we fail to obtain such regulatory approval, neither Sun Microsystems nor we would be obligated to consummate the merger unless such condition is waived.

In addition, the merger may be subject to review by authorities in various other jurisdictions under the antitrust laws of those jurisdictions.

The following description summarizes the material provisions of the merger agreement and the voting agreements. Shareholders should read carefully the merger agreement and the form of voting agreement, which are attached as Annexes A and B to this proxy statement.

THE REPRESENTATIONS AND WARRANTIES GIVEN BY TARANTELLA IN THE MERGER AGREEMENT ARE NOT INTENDED TO BE FOR THE BENEFIT OF OUR SHAREHOLDERS BUT RATHER ARE SOLELY FOR THE BENEFIT OF SUN MICROSYSTEMS AND ITS WHOLLY-OWNED MERGER SUB TO BE USED IN THE MERGER. THESE REPRESENTATIONS AND WARRANTIES ARE SUBJECT TO CERTAIN QUALIFICATIONS AND EXCEPTIONS WHICH WERE SET FORTH IN A DISCLOSURE LETTER DELIVERED BY US TO SUN MICROSYSTEMS AT THE TIME OF SIGNING OF THE MERGER AGREEMENT. THE CONTENTS OF THIS DISCLOSURE LETTER ARE HIGHLY CONFIDENTIAL AND HAVE NOT BEEN ATTACHED TO OR SUMMARIZED IN THIS PROXY STATEMENT.

Conditions to the Completion of the Merger. The parties’ obligations to effect the merger are subject to the satisfaction or waiver of various conditions, which include the following:

Sun Microsystems and we are obligated to effect the merger only if the following conditions are satisfied or waived:

Sun Microsystems will not be obligated to effect the merger unless the following conditions are satisfied or waived:

In addition, Sun Microsystems will not be obligated to complete the merger if there is a pending or threatened suit, action or proceeding asserted by any governmental entity:

We will not be obligated to effect the merger unless the following conditions are satisfied or waived:

Material Adverse Effect. The merger agreement provides that a “material adverse effect” is any change, event, violation, inaccuracy, circumstance or effect, that individually or when taken together with all other such changes, events, violations, inaccuracies, circumstances or effects, is (i) materially adverse to the business, assets, capitalization, financial condition or results of operations of us taken as a whole (but loss of customers resulting from the announcement or pendency of the merger will be deemed, in and of itself, to constitute a material adverse effect), or (ii) materially impedes the authority of us, or in any case Sun Microsystems, to consummate the transactions contemplated by the merger agreement. The merger agreement may be terminated by Sun Microsystems if a material adverse effect on us shall have occurred since the date of the merger agreement, provided that if such material adverse effect is curable by us prior to October 31, 2005 through the exercise of commercially reasonable efforts, then Sun Microsystems may not terminate the merger agreement prior to 30 days following the receipt of written notice from Sun Microsystems to us of such material adverse effect, provided that we continue to exercise commercially reasonable efforts to cure such material adverse effect through the 30-day period.

The merger agreement provides that the term “acquisition proposal” means any offer or proposal other than between Sun Microsystems and us relating to any transaction or series of related transactions involving:

We have agreed to promptly provide Sun Microsystems with oral and written notice of the material terms and conditions of any acquisition proposal or any request for nonpublic information or inquiry that we reasonably believe would lead to an acquisition proposal, the identity of the person or group making such an acquisition proposal, request or inquiry, and a copy of all written materials provided by or on behalf of such person or group in connection with the acquisition proposal, request or inquiry. We have also agreed to promptly provide Sun Microsystems with oral and written notice setting forth all information as is reasonably necessary to keep Sun Microsystems informed in all material respects of the status and details (including material amendments or proposed material amendments) of any such acquisition proposal, and a copy of all materials subsequently provided by or on behalf of such person or group in connection with the acquisition proposal. In addition, we have agreed to provide Sun Microsystems with 48 hours prior notice, or such lesser prior notice as is provided to our board of directors, of any meeting of our board of directors which could reasonably be expected to consider any acquisition proposal.

In the event we receive an unsolicited, bona fide written acquisition proposal from a third party that our board of directors has in good faith concluded (following the receipt of the advice of outside legal counsel and our financial adviser) is, or is reasonably likely to result in, a superior offer, we may then take the following actions (only if and to the extent that our board of directors concludes in good faith, following the receipt of

advice of outside legal counsel, that the failure to do so is reasonably likely to result in a breach of its fiduciary obligations under applicable law):

The merger agreement provides that the term “superior offer” means any unsolicited, bona fide written offer made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, consolidation or other business combination, all or substantially all of our assets or a majority of our total outstanding voting securities as a result of which our shareholders immediately preceding such transaction would hold less than 50% of the surviving or resulting entity and any direct or indirect parent or subsidiary thereof, on terms that our board of directors has concluded in good faith (following receipt of advice of its outside legal counsel and its financial adviser) to be more favorable from a financial point of view to our shareholders than the terms of the merger with Sun Microsystems and is reasonably capable of being consummated.

The merger agreement further provides that in response to the receipt of a superior offer, our board of directors may withhold, withdraw, amend or modify its unanimous recommendation in favor of the merger with Sun Microsystems. In the case of a superior offer that is a tender or exchange offer made directly to our shareholders, our board of directors may recommend that our shareholders accept the tender or exchange offer and release the person making the superior offer from any “standstill” obligation pursuant to agreements between such person and us if the following conditions are met:

Termination. Sun Microsystems and we can terminate the merger agreement under certain circumstances, including:

Shareholders’ Meeting. We have filed with the Securities and Exchange Commission this preliminary proxy statement relating to the merger within the time periods provided in the merger agreement. We have agreed to cause the mailing of the definitive proxy statement to occur on the date of the filing of the definitive proxy statement with the Securities and Exchange Commission or as promptly as reasonably practicable thereafter.

We have agreed in the merger agreement to hold our shareholders’ meeting to approve the principal terms of the merger within 45 days following the mailing of the definitive proxy statement. Under the merger agreement, we have the right to adjourn or postpone the shareholders’ meeting to the extent necessary to ensure that any necessary supplement or amendment to the proxy statement is provided to our shareholders in advance of a vote on the merger and the merger agreement or, if as of the time the meeting is originally scheduled, there are insufficient shares of our common stock represented at the meeting to constitute a quorum necessary to conduct business at the meeting.

Conduct of Business Pending the Merger. Under the merger agreement, we have agreed that prior to the effective time of the merger, subject to certain exceptions, unless we obtain Sun Microsystems’ written consent, we will and each of our subsidiaries will (i) carry on our and their businesses in the ordinary course, in substantially the same manner as has been conducted, and in compliance with all applicable laws and regulations, (ii) pay its debts and taxes when due, and (iii) use commercially reasonable efforts consistent with past practices and policies to preserve our and their present business organization, keep available the services of our present executive officers and employees and preserve our relationships with customers, suppliers and others with which we have business dealings.

In addition, we have agreed that neither we nor any of our subsidiaries may, without Sun Microsystems’ written consent:

Commercially Reasonable Efforts. Subject to the terms of the merger agreement, we, Cha Cha Acquisition Corporation and Sun Microsystems have each agreed to use our commercially reasonable efforts to take, or cause to be taken, all actions necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the merger and the other transactions contemplated by the merger agreement, including:

In addition, if any takeover statute or similar legal requirement is or becomes applicable to the merger, the merger agreement or any of the transactions contemplated by the merger agreement, we and our board of directors will use commercially reasonable efforts to ensure that the merger and the other transactions contemplated by the merger agreement may be consummated as promptly as practicable on the terms contemplated by the merger agreement and otherwise to minimize the effect of such legal requirement on the merger, the merger agreement and the transactions contemplated hereby

Amendment; Extension and Waiver. The merger agreement may be amended by Sun Microsystems, Cha Cha Acquisition Corporation and us by actions taken or authorized by our respective boards of directors at any time, before or after shareholder approval has been obtained. However, if the merger agreement is to be amended after shareholder approval has been obtained, no amendment will be allowed that by law or in accordance with the rules of any relevant stock exchange or Nasdaq requires further approval by shareholders of the parties without the further approval of those shareholders. Any amendment to the merger agreement must be in writing and signed by each of the parties.

Any extensions or waivers must be in writing signed by the party granting the extension of waiver.

Expenses. The merger agreement provides that regardless of whether the merger is consummated, all fees and expenses incurred by the parties in connection with the merger shall be borne by the party incurring such fees and expenses. However, both parties shall share equally any filing fee for any notification filed with U.S. antitrust authorities, and premerger notification and report forms under similar applicable laws of other jurisdictions.

Termination Fee. The merger agreement requires that we pay Sun Microsystems a termination fee of $1,200,000 if, any of the following events occur:

Representations and Warranties. The merger agreement contains customary representations and warranties. These representations and warranties are subject to qualifications and exceptions contained in a disclosure letter delivered by us to Sun Microsystems concurrently with the execution of the merger agreement. The contents of the disclosure letter are highly confidential and are not discussed in this proxy statement. The representations and warranties in the merger agreement relate to, among other things:

Tarantella Articles of Incorporation. As of the effective time of the merger, our articles of incorporation, as amended, will be amended and restated to be identical to the articles of incorporation of Cha Cha Acquisition Corporation as in effect immediately prior to the effective time of the merger except that the name of the surviving corporation will be Tarantella, Inc.

Tarantella By-Laws. The merger agreement provides that the by-laws of Cha Cha Acquisition Corporation immediately prior to the effective time of the merger will be the by-laws of the surviving corporation following the merger until changed or amended.

General. Simultaneously with the execution and delivery of the merger agreement, all of our executive officers and directors entered into voting agreements with Sun Microsystems. On June 8, 2005, these shareholders together owned and were entitled to vote 1,342,143 shares of our common stock, or approximately 4.8% of the outstanding shares of our common stock on that date.

Voting. The shareholders signing the voting agreements agreed, among other things, to vote their shares of our common stock in favor of the adoption of the merger agreement and in favor of the merger and its principal terms and in favor of actions contemplated by the merger agreement and this proxy at any meeting of our shareholders at which such matters are considered and at every adjournment or postponement thereof. The shareholders signing the agreements also agreed to vote against any acquisition proposal or material change in the capitalization or corporate structure of us or our subsidiaries, or any other action that is intended or could reasonably be expected to impede, interfere with, delay, postpone, discourage or adversely affect the merger or any transactions contemplated by the merger agreement in any material respect. The shareholders signing the voting agreements granted a proxy and power of attorney with respect to any of our shares that they owned with respect to such matters to certain officers of Sun Microsystems.

Restrictions on Transfer and Other Voting Arrangements. The shareholders party to the voting agreements have agreed not to assign, sell, transfer, tender, pledge, hypothecate, give, place in trust, constructively sell or otherwise dispose of any of our shares subject to the voting agreements prior to the earlier of the effective time of the merger or the time the merger agreement is terminated pursuant to its terms. In addition, the shareholders have agreed not to deposit any shares or options in a voting trust or grant any proxy or enter into any voting agreement in contravention of his or her obligations under the voting agreements.

Termination. The voting agreements provide that they will terminate upon the earlier of the effective time of the merger or the time the merger agreement is terminated pursuant to its terms.

The following table shows the common stock beneficially owned as of June 8, 2005 by:

Beneficial ownership is determined in accordance with Securities and Exchange Commission rules. In computing the number of shares beneficially owned by a person, we have included shares for which the named person has sole or shared power over voting or investment decisions. The number of shares beneficially owned includes common stock which the named person has the right to acquire, through conversion, option or warrant exercise, or otherwise, within 60 days after June 8, 2005. Percentage of beneficial ownership is based on 27,994,937 shares outstanding as of June 8, 2005. Shares of common stock subject to options currently exercisable or exercisable within sixty (60) days after June 8, 2005 are deemed outstanding for computing the percentage ownership of the person holding such options, but are not deemed outstanding for computing the percentage of any other person. Beneficial ownership calculations for 5% shareholders are based solely on publicly-filed Schedule 13Ds or 13Gs, which 5% shareholders are required to file with the Securities and Exchange Commission, and which generally set forth ownership interests as of June 8, 2005. Except as otherwise noted, the address of each person listed in the table is c/o Tarantella, Inc., 100 Albright Way, Suite D, Los Gatos, California, 95032.

We will hold a 2005 Annual Meeting of our Shareholders only if the merger is not completed.

Pursuant to Rule 14a-8 under the Exchange Act, shareholders may present proper proposals for inclusion in our proxy statement and for consideration at the 2005 Annual Meeting of Shareholders by submitting their proposals to us in a timely manner. In order to be included in our proxy material for the 2005 annual meeting of shareholders, shareholder proposals must have been received by us no later than January 28, 2005, and have complied with the requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended.

If a shareholder intends to submit a proposal or nomination for director for our 2005 Annual Meeting of Shareholders that is not to be included in our Proxy Statement and form of Proxy relating to the Annual Meeting, the shareholder must have given us notice in accordance with the requirements set forth in our bylaws no later than January 28, 2005. Our bylaws require that certain information and acknowledgments with respect to the proposal and the shareholder making the proposal be set forth in the notice.

As of the date of this proxy statement, our board of directors knows of no matters that will be presented for consideration at the special meeting other than as described in this proxy statement.

The Securities and Exchange Commission has adopted rules that permit companies and intermediaries such as brokers to satisfy delivery requirements for proxy statements with respect to two or more shareholders sharing the same address by delivering a single proxy statement addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for shareholders and cost savings for us. Under this procedure, multiple shareholders who share the same last name and address will receive only one copy of the annual proxy materials, unless they notify us that they wish to continue receiving multiple copies. We have undertaken householding to reduce our printing costs and postage fees. Shareholders also may request additional copies of the proxy materials by notifying us in writing at 100 Albright Way, Suite D, Los Gatos, California 95032, or contacting us at 408-341-7400, and we will undertake to deliver such additional copies promptly. If a shareholder shares an address with another shareholder and currently is receiving multiple copies of the proxy materials, such shareholder may request householding by notifying us at the above-referenced address or telephone number.

Sun Microsystems and we file annual, quarterly and special reports, proxy statements and other information with the Securities and Exchange Commission. You may read and copy any reports, statements or other information that Sun Microsystems and we file with the Securities and Exchange Commission at the Securities and Exchange Commission’s public reference room at the following location:

Please call the Securities and Exchange Commission at 1-800-SEC-0330 for further information on the public reference room. These Securities and Exchange Commission filings are also available to the public from commercial document retrieval services and at the Internet World Wide Web site maintained by the Securities and Exchange Commission at “http://www.sec.gov.”

Our shareholders should not send in their Tarantella certificates until they receive the transmittal materials from the paying agent. Our shareholders of record who have further questions about their share certificates or the exchange of our common stock for cash should contact the paying agent.

You should rely only on the information contained in this proxy statement. We have not authorized anyone to provide you with information that is different from what is contained in this proxy statement. This proxy statement is dated June 10, 2005. You should not assume that the information contained in this proxy statement is accurate as of any date other than that date (or as of an earlier date if so indicated in this proxy statement). Neither the mailing of this proxy statement to shareholders nor the issuance of cash in the merger creates any implication to the contrary.

1.4 Articles of Incorporation and Bylaws. Unless otherwise determined by Parent prior to the Effective Time, at the Effective Time, the Articles of Incorporation of the Company shall be amended and restated in their entirety to be identical to the Articles of Incorporation of Merger Sub, as in effect immediately prior to the Effective Time, until thereafter amended in accordance with California Law and as provided in such Articles of Incorporation; provided, however, that at the Effective Time, Article I of the Articles of Incorporation of the Surviving Corporation shall be amended and restated in its entirety to read as follows: “The name of the corporation is Tarantella, Inc.” and the Articles of Incorporation shall be amended so as to comply with Section 5.11(a). Unless otherwise determined by Parent prior to the Effective Time, at the Effective Time, the Bylaws of the Company shall be amended and restated in their entirety to be identical to the Bylaws of Merger Sub, as in effect immediately prior to the Effective Time, until thereafter amended in accordance with California Law and as provided in such Bylaws; provided, however, that at the Effective Time, the Bylaws shall be amended so as to comply with Section 5.11(a).

1.5 Directors and Officers. Unless otherwise determined by Parent prior to the Effective Time, the initial directors of the Surviving Corporation shall be the directors of Merger Sub immediately prior to the Effective Time, until their respective successors are duly elected or appointed and qualified. Unless otherwise determined by Parent prior to the Effective Time, the initial officers of the Surviving Corporation shall be the officers of Merger Sub immediately prior to the Effective Time, until their respective successors are duly appointed. In addition, unless otherwise determined by Parent prior to the Effective Time, Parent, the Company and the Surviving Corporation shall cause the directors and officers of Merger Sub immediately prior to the Effective Time to be the directors and officers, respectively of each of the Company’s Subsidiaries immediately after the Effective Time, each to hold office as a director of each such Subsidiary in accordance with the provisions of the laws of the respective jurisdiction of organization and the respective bylaws or equivalent organizational documents of each such Subsidiary.

1.6 Effect on Capital Stock. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, the Company or the holders of any shares of capital stock of the Company, the following shall occur:

(a) Company Common Stock. Each share of the Common Stock, no par value, of the Company (together with the associated Company Right under the Company Rights Agreement) (“Company Common Stock”) issued and outstanding immediately prior to the Effective Time, other than any shares of Company Common Stock to be canceled pursuant to Section 1.6(d) or Dissenting Shares as provided in Section 1.7, will be canceled and extinguished and automatically converted into the right to receive an amount of cash equal to $0.90, without interest (such amount of cash hereinafter referred to as the “Merger Consideration”) upon surrender of the certificate representing such share of Company Common Stock in the manner provided in Section 1.8 (or in the case of a lost, stolen or destroyed certificate, upon delivery of an affidavit (and bond, if required) in the manner provided in Section 1.10).

(b) Repurchase Rights. If any shares of Company Common Stock outstanding immediately prior to the Effective Time are subject to a repurchase right in favor of the Company, risk of forfeiture to the Company or other similar condition under any applicable restricted stock purchase agreement or other agreement with the Company (“Company Unvested Common Stock”) which right, risk of forfeiture or other similar condition is not terminated as of the Effective Time, then, the amounts payable with respect to such shares of Company Unvested Common Stock pursuant to the provisions of Section 1.6(a) shall be withheld and retained by Parent and shall be subject to permanent retention by Parent (i.e., forfeiture by the former holder of such shares of Company Unvested Common Stock) on the same terms that governed such Company Unvested Common Stock prior to the Effective Time. Parent shall hold the cash so withheld for the benefit of such former holder (unless such cash is forefeited and permanently retained by Parent as set forth herein) of Company Unvested Common Stock until such cash is no longer subject to retention by Parent, at which time such withheld cash will be paid to such former holder of the applicable Company Unvested Common Stock on a monthly basis as reasonably determined by Parent.

(c) Company Warrants and Non-Employee Options. Following the Effective Time, all outstanding warrants to purchase Company Common Stock (“Company Warrants”) shall represent only the right, upon the valid exercise thereof, if any, to receive the Merger Consideration payable upon the shares of Company Common Stock previously issuable upon exercise of such Company Warrants and shall in no event be exercisable for any equity securities of Parent, the Company or any of their Subsidiaries. In addition, the Company shall use commercially reasonable efforts to have all holders of Company Warrants either fully exercise such Company Warrants prior to the Effective Time or agree that such Company Warrants shall be terminated upon the Effective Time, provided that the holder of any such terminated Company Warrant shall be entitled to receive following the Effective Time upon surrender of the certificate representing such Company Warrant in accordance with Section 1.8 an amount equal to the product of (x) the number of shares of Company Common Stock issuable upon exercise of such Company Warrant multiplied by (y) the excess, if any, of the per share Merger Consideration over the per share exercise price in effect for such Company Warrant. At the Effective Time, each Company Option held by any person other than an employee of the Company or any of its Subsidiaries (each such Company Option, a “Non-Employee Option”) that is unexpired, unexercised and outstanding immediately prior to the Effective Time shall, on the terms and subject to the conditions set forth in this Agreement, terminate in its entirety at the Effective Time, and the holder of each Non-Employee Option shall be entitled to receive therefor an amount of cash (rounded down to the nearest whole cent) equal to the product of (i) the number of shares of Company Common Stock as to which such Company Option was vested and exercisable immediately prior to the Effective Time (giving effect to any acceleration of vesting resulting from the Merger), and (ii) the per share Merger Consideration minus the exercise price of such Company Option immediately prior to the Effective Time (the “Non-Employee Option Cash-Out Amount”); provided, however, that if the per share Merger Consideration does not exceed the exercise price of such Non-Employee Option immediately prior to the Effective Time, the Non-Employee Option Cash-Out Amount for such Non-Employee Option shall be zero; provided further, that nothing in this Section 1.6(c) shall prohibit the holder of a Non-Employee Option from exercising such Non-Employee Option prior to the Effective Time in accordance with its terms. Prior to the Effective Time, the Company shall timely deliver any notices to holders of Non-Employee Options as may be required by the terms of the Stock Option Plans. Any materials to be submitted to the holders of Company Warrants or Non-Employee Options shall be subject to review and approval by Parent.

(d) Cancellation of Treasury and Parent Owned Stock. Each share of Company Common Stock held by Company or Parent or any direct or indirect wholly-owned Subsidiary of the Company or of Parent immediately prior to the Effective Time shall be canceled and extinguished without any conversion thereof.

(e) Capital Stock of Merger Sub. Each share of common stock, no par value, of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, no par value, of the Surviving Corporation. Each certificate evidencing ownership of shares of Merger Sub Common Stock shall evidence ownership of such shares of capital stock of the Surviving Corporation.

(f) Employee Stock Options; Employee Stock Purchase Plans. At the Effective Time, all Company Options, other than Non-Employee Options, outstanding under each Company Stock Option Plan shall be assumed by Parent in accordance with Section 5.9. Rights outstanding under the Company’s Employee Stock Purchase Plan and any other employee stock purchase plan of the Company (collectively, the “Company Purchase Plans”) shall be treated as set forth in Section 5.9(c).

(g) Adjustments to Merger Consideration. The Merger Consideration shall be adjusted to reflect fully the appropriate effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Company Common Stock), reorganization, recapitalization, reclassification or other like change with respect to Company Common Stock having a record date on or after the date hereof and prior to the Effective Time.

(a) Notwithstanding any other provisions of this Agreement to the contrary, any shares of Company Common Stock held by a holder who has not effectively withdrawn or lost such holder’s dissenters’ rights under Chapter 13 of California Law (collectively, the “Dissenting Shares”), shall not be converted into or represent a right to receive the applicable consideration for Company Common Stock set forth in Section 1.6, but the holder thereof shall only be entitled to such rights as are provided by California Law.

(b) Notwithstanding the provisions of Section 1.7(a), if any holder of Dissenting Shares shall effectively withdraw or lose (through failure to perfect or otherwise) such holder’s dissenters’ rights under California Law, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares shall automatically be converted into and represent only the right to receive the consideration for Company Common Stock, as applicable, set forth in Section 1.6, without interest thereon, upon surrender of the certificate representing such shares.

(c) The Company shall give Parent (i) prompt notice of any written demand for appraisal received by the Company pursuant to the applicable provisions of California Law, and (ii) the opportunity to participate in all negotiations and proceedings with respect to such demands. The Company shall not, except with the prior written consent of Parent, make any payment with respect to any such demands or offer to settle or settle any such demands. Any communication to be made by the Company to any holder of Company Common Stock with respect to such demands shall be submitted to Parent in advance and shall not be presented to any holder of Company Common Stock prior to the Company receiving Parent’s consent.

(a) Exchange Agent. Prior to the Effective Time, Parent shall select an institution reasonably acceptable to the Company to act as the exchange agent (the “Exchange Agent”) for the Merger.

(b) Parent to Provide Cash. Prior to the Effective Time, Parent shall enter into an agreement with the Exchange Agent that shall provide that Parent shall, within two Business Days following the Effective Time, make available to the Exchange Agent for exchange in accordance with this Article I, the Merger Consideration payable pursuant to Section 1.6(a) in exchange for outstanding shares of Company Common Stock. Any cash deposited with the Exchange Agent shall hereinafter be referred to as the “Exchange Fund.”

(c) Exchange Procedures. As soon as practicable following the Effective Time, Parent shall cause the Exchange Agent to mail to each holder of record (as of the Effective Time) of a certificate or certificates (the “Certificates”) which immediately prior to the Effective Time represented outstanding shares of Company Common Stock whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.6(a), Non-Employee Options or Company Warrants whose Non-Employee Options or Company Warrants were converted into the right to receive cash as provided in Section 1.6(c): (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates, Non-Employee Options or Company Warrants shall pass, only upon delivery of the Certificates, Non-Employee Options or Company Warrants to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the

surrender of the Certificates, Non-Employee Options or Company Warrants in exchange for cash constituting the Merger Consideration. Upon surrender of Certificates, Non-Employee Options or Company Warrants for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and such other documents as may reasonably be required by the Exchange Agent, the holder of record of such Certificates, Non-Employee Options or Company Warrants shall be entitled to receive in exchange therefor the cash as provided in Section 1.6, and the Certificates, Non-Employee Options or Company Warrants so surrendered shall forthwith be canceled. Subject to the terms and conditions of this Article I, Parent shall cause the Exchange Agent to pay the Merger Consideration as provided in Section 1.6. Until so surrendered, outstanding Certificates, Non-Employee Options or Company Warrants will be deemed from and after the Effective Time, for all corporate purposes, to evidence the ownership of the cash as provided in Section 1.6 into which such shares of Company Common Stock, Non-Employee Options or Company Warrants shall have been so converted.

(d) Required Withholding. Each of the Exchange Agent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Company Common Stock, Company Options or Company Warrants such amounts as are required to be deducted or withheld therefrom under the Internal Revenue Code of 1986, as amended (the “Code”) or under any provision of state, local or foreign Tax law or under any other applicable Legal Requirement. To the extent such amounts are so deducted or withheld, the amount of such consideration shall be treated for all purposes under this Agreement as having been paid to the Person to whom such consideration would otherwise have been paid.

(e) No Liability. Notwithstanding anything to the contrary in this Section 1.8, neither the Exchange Agent, the Surviving Corporation nor any party hereto shall be liable to a holder of shares of Company Common Stock or Company Warrants for any amount paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

(f) Expenses; Investment of Exchange Fund. The expenses of the Exchange Agent shall not be paid from the Exchange Fund but shall be paid directly by the Surviving Corporation or Parent. If the amount of cash in the Exchange Fund is insufficient to pay all of the amounts required to be paid pursuant to Section 1.6, Parent, from time to time after the Effective Time, shall deposit additional cash with the Exchange Agent sufficient to make all such payments. The Exchange Agent shall invest the cash included in the Exchange Fund as directed by Parent on a daily basis; provided that no such investment or loss thereon shall affect the amounts payable to Company securityholders pursuant to this Article I. Any interest and other income resulting from such investment shall become a part of the Exchange Fund, and any amounts in excess of the amounts payable to Company securityholders pursuant to this Article I shall promptly be paid to Parent.

(g) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Certificates, Non-Employee Options or Company Warrants one year after the Effective Time shall, at the request of the Surviving Corporation, be delivered to the Surviving Corporation or otherwise according to the instruction of the Surviving Corporation, and any holders of the Certificates, Non-Employee Options or Company Warrants who have not surrendered such Certificates, Non-Employee Options or Company Warrants in compliance with this Section 1.8 shall after such delivery to Surviving Corporation look only to the Surviving Corporation solely as general creditors for the cash into which such Certificates, Non-Employee Options or Company Warrants have been converted (which shall not accrue interest) pursuant to Section 1.6(a) or Section 1.6(c) with respect to the shares of Company Common Stock, Non-Employee Options or Company Warrants formerly represented thereby.

1.9 No Further Ownership Rights in Company Common Stock, Non-Employee Options or Company Warrants. All consideration paid pursuant hereto upon the surrender for exchange of shares of Company Common Stock, Non-Employee Options or Company Warrants in accordance with the terms hereof shall be deemed to have been paid in full satisfaction of all rights pertaining to such shares of Company Common Stock,

Non-Employee Options or Company Warrants, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of Company Common Stock, Non-Employee Options or Company Warrants which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates, Non-Employee Options or Company Warrants are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article I.

1.10 Lost, Stolen or Destroyed Certificates, Non-Employee Options or Company Warrants. In the event any Certificates, Non-Employee Options or Company Warrants shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, Non-Employee Options or Company Warrants, upon the making of an affidavit of that fact by the holder thereof, such cash payable pursuant to Section 1.6; provided, however, that Parent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates, Non-Employee Options or Company Warrants to deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against Parent, the Company or the Exchange Agent with respect to the Certificates, Non-Employee Options or Company Warrants alleged to have been lost, stolen or destroyed.

1.11 Further Action. At and after the Effective Time, the officers and directors of Parent and the Surviving Corporation will be authorized to execute and deliver, in the name and on behalf of the Company and Merger Sub, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Company and Merger Sub, any other actions and things to vest, perfect or confirm of record or otherwise in the Surviving Corporation any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger.

The Company represents and warrants to Parent and Merger Sub, subject to the exceptions specifically disclosed in writing in the disclosure letter (referencing the appropriate section, subsection, paragraph and subparagraph numbers; provided, that disclosure in any section of such letter shall be deemed to be disclosed with respect to any other section of Article II of this Agreement to the extent that it is readily apparent from the face of such disclosure that such disclosure is applicable to such other section) supplied by Company to Parent dated as of the date hereof and certified by a duly authorized executive officer of Company (the “Company Disclosure Letter”), as follows:

(a) Organization; Standing and Power. The Company and each of its Subsidiaries (i) is a corporation or other organization duly organized, validly existing and is in good standing under the laws of the jurisdiction of its incorporation or organization (except, in the case of good standing, for entities organized under the laws of any jurisdiction that does not recognize such concept), (ii) has the requisite power and authority to own, lease and operate its properties and to carry on its business as currently conducted and as currently proposed to be conducted, and (iii) is duly qualified or licensed to do business and in good standing as a foreign corporation in each jurisdiction in which the character or location of its assets or properties (whether owned, leased or licensed) or the nature of its business makes such qualification or licensing necessary, except for such failures to be so organized, qualified or in good standing as are not material to the Company and its Subsidiaries. For purposes of this Agreement, “Subsidiary,” when used with respect to any party, shall mean any corporation, association, business entity, partnership, limited liability company or other Person of which such party, either alone or together with one or more Subsidiaries or by one or more Subsidiaries (i) directly or indirectly owns or controls securities or other interests representing more than 50% of the voting power of such Person, or (ii) is entitled, by Contract or otherwise, to elect, appoint or designate directors constituting a majority of the members of such Person’s board of directors or other governing body.

The Company is not in violation of any of the provisions of the Company Charter Documents and each Subsidiary is not in violation of its respective Subsidiary Charter Documents.

(c) Subsidiaries. Section 2.1(c) of the Company Disclosure Letter sets forth each Subsidiary of the Company. The Company is the owner of all the outstanding shares of capital stock of, or other equity or voting interests in, each such Subsidiary and all such shares have been duly authorized, validly issued and are fully paid and nonassessable, free and clear of all pledges, claims, liens, charges, encumbrances, options and security interests of any kind or nature whatsoever (collectively, “Liens”), including any restriction on the right to vote, sell or otherwise dispose of such capital stock or other ownership interests, except for restrictions imposed by applicable securities laws. Other than the Subsidiaries of the Company, neither the Company nor any of its Subsidiaries owns any capital stock of, or other equity or voting interests of any nature in, or any interest convertible, exchangeable or exercisable for, capital stock of, or other equity or voting interests of any nature in, any other Person, except for passive investments of less than 1% in the equity interests of public companies as part of the Company’s cash management program.

Neither the Company nor any of its Subsidiaries has violated any provision of, or committed or failed to perform any act which, with or without notice, lapse of time or both would constitute a default under the provisions of, any Company Material Contract, except in each case for those violations and defaults which, individually or in the aggregate, would not reasonably be expected to be material to the Company.

(d) Consents. The Company is not party to, subject to, or bound by any agreement that (i) requires the Company to give any notice to any third party regarding the transaction contemplated by this Agreement or (ii) that would give any third party any option, right of first refusal or offer, right of negotiation or similar right with respect to the acquisition of the Company, any Subsidiary or any of their respective assets, or the licensing of any Company Intellectual Property.

Without limiting the foregoing:

(a) The Company and each of its Subsidiaries has obtained all export licenses, license exceptions and other consents, notices, waivers, approvals, orders, authorizations, registrations, declarations, classifications and filings with any Governmental Entity required for (i) the export and reexport of products, services, software and technologies and (ii) releases of technologies and software to foreign nationals located in the United States and abroad (“Export Approvals”);

2.20 Information Supplied. None of the information supplied or to be supplied by or on behalf of the Company for inclusion or incorporation by reference in the preliminary and definitive proxy statements to be filed by the Company with the SEC in connection with the Merger (collectively, the “Proxy Statement”) will not, on each relevant filing date, on the date of mailing to the Company’s shareholders and at the time of the Shareholders’ Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading.

The execution and delivery by Parent and Merger Sub of this Agreement and the consummation of the transactions contemplated hereby, will not (i) conflict with or violate any provision of the Certificate of Incorporation, Articles of Incorporation or bylaws of such entity, (ii) subject to obtaining the Necessary Consents, conflict with or violate any material Legal Requirement applicable to Parent or Merger Sub or by which Parent or Merger Sub or any of their respective properties or assets (whether tangible or intangible) is bound or affected, or (iii) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under any contract filed by Parent with the SEC, except, in each case under the preceding clauses (i), (ii) and (iii), for any conflicts, violations, breaches or defaults which would not materially adversely affect the ability of the parties hereto to consummate the Merger within the time frame in which the Merger would otherwise be consummated.

indirectly: (i) solicit, initiate, induce or knowingly facilitate or encourage any inquiry with respect to, or the making, submission or announcement of, any Acquisition Proposal, (ii) subject to Section 5.3(c), participate in any discussions or negotiations regarding, or furnish to any Person any nonpublic information with respect to, or take any other action reasonably likely or intended to facilitate any inquiries or the making of any proposal that constitutes or could reasonably be expected to lead to, any Acquisition Proposal, (iii) subject to Section 5.3(c), engage in discussions with any Person with respect to any Acquisition Proposal, except to notify such Person as to the existence of these provisions, (iv) approve, endorse or recommend any Acquisition Proposal (except to the extent specifically permitted pursuant to Section 5.3(d)), or (v) enter into any letter of intent or similar document or any contract agreement or commitment contemplating or otherwise relating to any Acquisition Proposal or transaction contemplated thereby.

Upon receipt of an Acquisition Proposal, request or inquiry, the Company shall provide Parent as promptly as practicable oral and written notice setting forth all such information as is reasonably necessary to keep Parent informed in all material respects of the status and details (including material amendments or proposed material amendments) of any such Acquisition Proposal, request or inquiry and shall promptly provide Parent a copy of all written materials subsequently provided by or on behalf of such Person or group in connection with such Acquisition Proposal, request or inquiry.

(ii) The Company shall provide Parent with 48 hours prior notice (or such lesser prior notice as is provided to the members of its Board of Directors) of any meeting of its Board of Directors at which its Board of Directors could reasonably be expected to consider any Acquisition Proposal.

(c) Superior Offers.

(i) Request information from the Person making such Acquisition Proposal to the extent required for the Board of Directors of the Company to become appropriately informed about the Acquisition Proposal that has been made and the Person that made it;

(ii) Furnish nonpublic information to the third party making such Acquisition Proposal, provided that (a) (1) concurrently with furnishing any such nonpublic information to such party, the Company gives Parent written notice of its intention to furnish such nonpublic information and (2) the Company receives from the third party an executed confidentiality agreement containing customary limitations on the use and disclosure of all nonpublic written and oral information furnished to such third party on the Company’s behalf, the terms of which are at least as restrictive as the terms contained in the Confidentiality Agreement and (b) contemporaneously with furnishing any such nonpublic information to such third party, the Company furnishes such nonpublic information to Parent (to the extent such nonpublic information has not been previously so furnished); and

(iii) Engage in negotiations with the third party with respect to the Acquisition Proposal, provided that concurrently with entering into negotiations with such third party, the Company gives Parent written notice of the Company’s intention to enter into negotiations with such third party.

(d) Change of Recommendation. In response to the receipt of a Superior Offer, the Board of Directors of the Company may withhold, withdraw, amend or modify its unanimous recommendation in favor of the Merger, and, in the case of a Superior Offer that is a tender or exchange offer made directly to the shareholders of the Company, may recommend that the shareholders of the Company accept the tender or exchange offer and release the Person making the Superior Offer from any “standstill” obligation pursuant to agreements between such Person and the Company (any of the foregoing actions, whether by the Board of Directors of the Company or a committee thereof, a “Change of Recommendation”), if all of the following conditions in clauses (i) through (v) are met:

(i) A Superior Offer with respect to the Company has been made and has not been withdrawn;

(iii) The Company shall have (a) delivered to Parent written notice (a “Change of Recommendation Notice”) at least three Business Days prior to publicly effecting such Change of Recommendation which shall state expressly (1) that the Company has received a Superior Offer, (2) the material terms and conditions of the Superior Offer and the identity of the Person or group making the Superior Offer, and (3) that the Company intends to effect a Change of Recommendation and the manner in which it intends to do so, (b) provided to Parent a copy of all written materials delivered to the Person or group making the Superior Offer in connection with such Superior Offer (to the extent not previously provided to Parent), and (c) made available to Parent all materials and information made available to the Person or group making the Superior Offer in connection with such Superior Offer;

(iv) During the at least three Business Day period from delivery to Parent of the Change of Recommendation Notice until the effecting of any Change of Recommendation, the Company shall provide Parent with a reasonable opportunity to make such adjustments in the terms and conditions of this Agreement, and negotiate in good faith with respect thereto, as would enable the Company to proceed with its recommendation to shareholders in favor of approval and adoption of this Agreement and Approval of the Merger without making a Change of Recommendation.

(v) The Board of Directors of the Company has concluded in good faith, after receipt of advice of its outside legal counsel (which may be O’Melveny & Myers LLP), that, in light of such Superior Offer and after considering any adjustments or negotiations pursuant to the preceding clause (iv), that the failure of the Board of Directors to effect a Change of Recommendation is reasonably likely to result in a breach of its fiduciary obligations to the shareholders of the Company under applicable law; and

(vi) The Company shall not have breached any of the provisions set forth in Section 5.2 or this Section 5.3.

(e) Continuing Obligation to Call, Hold and Convene Shareholders’ Meeting; No Other Vote. Notwithstanding anything to the contrary contained in this Agreement, the obligation of the Company to call, give notice of, convene and hold the Shareholders’ Meeting shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission to it of any Acquisition Proposal, or by any Change of Recommendation. The Company shall not submit to the vote of its shareholders any Acquisition Proposal, or publicly propose to do so unless this Agreement has been validly terminated in accordance with Article VII hereof.

(f) Compliance with Tender Offer Rules. Nothing contained in this Agreement shall prohibit the Company or its Board of Directors from taking and disclosing to the shareholders of the Company a position contemplated by Rules 14d-9 and 14e-2(a) promulgated under the Exchange Act; provided that the content of any such disclosure thereunder shall be governed by the terms of this Agreement. Without limiting the foregoing proviso, the Company shall not effect a Change of Recommendation unless specifically permitted pursuant to the terms of Section 5.3(d).

(g) Certain Definitions. For purposes of this Agreement, the following terms shall have the following meanings:

The parties hereto agree that irreparable damage would occur in the event that the provisions of this Section 5.3 were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed by the parties hereto that Parent shall be entitled to an immediate injunction or injunctions, without the necessity of proving the inadequacy of money damages as a remedy and without the necessity of posting any bond or other security, to prevent breaches of the provisions of this Section 5.3 and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which Parent may be entitled at law or in equity. Without limiting the foregoing, it is understood that any violation of the restrictions set forth above by any officer, director, agent, representative or affiliate of the Company shall be deemed to be a breach of this Agreement by the Company.

No information or knowledge obtained in any investigation or notification pursuant to this Section 5.4, Section 5.6 or Section 5.7 shall affect or be deemed to modify any representation or warranty contained herein, the covenants or agreements of the parties hereto or the conditions to the obligations of the parties hereto under this Agreement.

5.5 Public Disclosure. Without limiting any other provision of this Agreement, Parent and the Company will consult with each other before issuing, and provide each other the opportunity to review, comment upon and concur with, and use commercially reasonable efforts to agree on any press release or public statement with respect to this Agreement and the transactions contemplated hereby, including the Merger, and any Acquisition Proposal and will not issue any such press release or make any such public statement prior to such consultation and (to the extent practicable) agreement, except as may be required by law or any listing agreement with the Nasdaq or any other applicable national or regional securities exchange or market. The parties have agreed to the text of the joint press release announcing the signing of this Agreement.

(a) Regulatory Filings. Each of Parent, Merger Sub and the Company shall coordinate and cooperate with one another and shall each use commercially reasonable efforts to comply with, and shall each refrain from taking any action that would impede compliance with, all Legal Requirements, and each of Parent, Merger Sub and the Company shall make all filings, notices, petitions, statements, registrations, submissions of information, application or submission of other documents required by any Governmental Entity in connection with the Merger and the transactions contemplated hereby as promptly as practicable after the date hereof (or as promptly as practicable following the occurrence of any events that cause any such filing, notice, petition, statement, registration, submission or application to be reasonably likely to be required), including, without limitation: (i) Notification and Report Forms with the FTC and the DOJ if required by the HSR Act, (ii) filings under any other comparable pre-merger notification forms reasonably determined by Parent to be required by the merger notification or control laws of any applicable jurisdiction, as agreed by the parties hereto, and (iii) any filings required under the Securities Act, the Exchange Act, any applicable state or securities or “blue sky” laws and the securities laws of any foreign country, or any other Legal Requirement relating to the Merger. Each of Parent and the Company will cause all documents that it is responsible for filing with any Governmental Entity under this Section 5.6(a) to comply in all material respects with all applicable Legal Requirements.

(b) Exchange of Information. Parent, Merger Sub and the Company each shall promptly supply the other with any information that may be required in order to effectuate any filings or application pursuant to Section 5.6(a). Except where prohibited by applicable Legal Requirements, and subject to the Confidentiality Agreement, each of the Company and Parent shall consult with the other prior to taking a position with respect to any such filing, shall permit the other to review and discuss in advance, and consider in good faith the views of the other in connection with any analyses, appearances, presentations, memoranda, briefs, white papers, arguments, opinions and proposals before making or submitting any of the foregoing to any Governmental Entity by or on behalf of any party hereto in connection with any investigations or proceedings in connection with this Agreement or the transactions contemplated hereby (including under any antitrust or fair trade Legal Requirement), coordinate with the other in preparing and exchanging such information and promptly provide the other (and its counsel) with copies of all filings, presentations or submissions (and a summary of any oral presentations) made by such party with any Governmental Entity in connection with this Agreement or the transactions contemplated hereby, provided that with respect to any such filing, presentation or submission, each of Parent and the Company need not supply the other (or its counsel) with copies (or in the case of oral presentations, a summary) to the extent that any law, treaty, rule or regulation of any Governmental Entity applicable to such party requires such party or its Subsidiaries to restrict or prohibit access to any such properties or information.

(c) Notification. Each of Parent, Merger Sub and the Company will notify the other promptly upon the receipt of: (i) any comments from any officials of any Governmental Entity in connection with any filings made pursuant hereto and (ii) any request by any officials of any Governmental Entity for amendments or supplements to any filings made pursuant to, or information provided to comply in all material respects with, any Legal Requirements.

(d) Reasonable Efforts. Subject to the express provisions of Section 5.2 and Section 5.3 hereof and upon the terms and subject to the conditions set forth herein, each of the parties agrees to use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including using commercially reasonable efforts to accomplish the following: (i) the taking of commercially reasonable acts necessary to cause the conditions precedent set forth in Article VI to be satisfied, (ii) the obtaining of all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from Governmental Entities and the making of all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities, if any) and the taking of commercially reasonable steps as may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity, (iii) the obtaining of all necessary consents, approvals or waivers from third parties, (iv) the defending of any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby and (v) the execution or delivery of any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement. In connection with and without limiting the foregoing, the Company and its Board of Directors shall, if any takeover statute or similar Legal Requirement is or becomes applicable to the Merger, this Agreement or any of the transactions contemplated by this Agreement, use commercially reasonable efforts to ensure that the Merger and the other transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise to minimize the effect of such Legal Requirement on the Merger, this Agreement and the transactions contemplated hereby.

(e) Limitation on Divestiture. Notwithstanding anything in this Agreement to the contrary, nothing contained in this Agreement shall be deemed to require Parent or the Company or any Subsidiary or affiliate thereof to agree to any Action of Divestiture. The Company shall not take or agree to take any Action of Divestiture without the prior written consent of Parent. For purposes of this agreement, an “Action of Divestiture” shall mean (x) any license, sale or other disposition or holding separate (through establishment of a trust or otherwise) of any shares of capital stock or of any business, assets or properties of Parent, its subsidiaries or affiliates or of the Company or its Subsidiaries, (y) the imposition of any limitation on the ability of Parent, its subsidiaries or affiliates or the Company or its Subsidiaries to conduct their respective businesses or own any capital stock or assets or to acquire, hold or exercise full rights of ownership of their respective businesses and, in the case of Parent, the businesses of the Company and its Subsidiaries, or (z) the imposition of any impediment on Parent, its subsidiaries or affiliates or the Company or its Subsidiaries under any statute, rule, regulation, executive order, decree, order or other legal restraint governing competition, monopolies or restrictive trade practices. In addition, nothing herein shall require Parent to litigate with any Governmental Entity.

(a) By the Company. The Company shall give prompt notice to Parent and Merger Sub of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of the Company to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 6.2(a) or 6.2(b) would not be satisfied.

(b) By Parent. Parent and Merger Sub shall give prompt notice to the Company of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of Parent to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, in each case, such that the conditions set forth in Section 6.3(a) or 6.3(b) would not be satisfied.

5.8 Third-Party Consents. As soon as practicable following the date hereof, the Company will use commercially reasonable efforts to obtain any material consents, waivers and approvals under any of its or its Subsidiaries’ respective Contracts required to be obtained in connection with the consummation of the transactions contemplated hereby, including all consents, waivers and approvals set forth in Section 2.3(b) of the Company Disclosure Letter. In connection with seeking such consents, waivers and approvals, the Company shall keep Parent informed of all material developments and, shall at Parent’s request, include Parent in any discussions or communications with any parties whose consent, waiver or approval is sought hereunder. Such consents, waivers and approvals shall be in a form reasonably acceptable to Parent. In the event the Merger does not close for any reason, Parent shall not have any liability to the Company or its shareholders for any costs, claims, liabilities or damages resulting from the Company seeking to obtain such consents, waivers and approvals.

(a) Assumption of Employee Stock Options. At the Effective Time, each then outstanding Company Option (other than Non-Employee Options), whether or not exercisable at the Effective Time and regardless of the respective exercise prices thereof, will be assumed by Parent. Each Company Option so assumed by Parent under this Agreement will continue to have, and be subject to, the same terms and conditions set forth in the applicable Company Option (including any applicable stock option agreement or other document evidencing such Company Option) immediately prior to the Effective Time (including any repurchase rights or vesting provisions), except that (i) each such Company Option will be exercisable (or will become exercisable in accordance with its terms) for that number of whole shares of Parent Common Stock equal to the product of the number of shares of Company Common Stock that were issuable upon exercise of such Company Option immediately prior to the Effective Time multiplied by the ratio of the value of the per share Merger Consideration to the average of the average closing prices for a share of Parent Common Stock on the ten trading days ended one trading day prior to the Closing Date (such ratio, the “Option Ratio”), rounded down to the nearest whole number of shares of Parent Common Stock and (ii) the per share exercise price for the shares of Parent Common Stock issuable upon exercise of such assumed Company Option will be equal to the quotient determined by dividing the exercise price per share of Company Common Stock at which such Company Option was exercisable immediately prior to the Effective Time by the Option Ratio, rounded up to the nearest whole cent. Each assumed Company Option shall be vested immediately following the Effective Time as to the same percentage of the total number of shares subject thereto as it was vested as to immediately prior to the Effective Time and the Company shall take any and all actions necessary to provide that the vesting of Company Options of all Company Employees offered an employment position with Parent prior to the Closing Date shall not accelerate in connection with the transactions contemplated by this Agreement, except as otherwise provided in Section 1.6(c), Section 5.9(e) and Section 5.9(f). As soon as reasonably practicable, Parent will use all reasonable efforts to issue to each Person who holds an assumed Company Option a document evidencing the foregoing assumption of such Company Option by Parent and, as a condition to such assumption, each former holder of a Company Option so assumed by Parent shall acknowledge the receipt of the same in exchange for such holder’s Company Option.

(b) Incentive Stock Options. The conversion of Company Options provided for in Section 5.9(a), with respect to any options which are intended to be “incentive stock options” (as defined in Section 422 of the Code) shall be effected in a manner consistent with Section 424(a) of the Code.

(c) Termination of Company Employee Stock Purchase Plans. Prior to the Effective Time, each of the Company Purchase Plans shall be terminated. The rights of participants in each Company Purchase Plan

with respect to any offering period then underway under such Company Purchase Plan shall be determined by treating the last Business Day prior to, or if more administratively advisable, the last payroll date of the Company immediately prior to, the Effective Time, as the last day of such offering period and by making such other pro-rata adjustments as may be necessary to reflect the shortened offering period but otherwise treating such shortened offering period as a fully effective and completed offering period for all purposes under such Company Purchase Plan. Prior to the Effective Time, the Company shall take all actions (including, if appropriate, amending the terms of such the Company Purchase Plan and timely distributing any notices required by the terms of the Company Purchase Plans) that are necessary to give effect to the transactions contemplated by this Section 5.9(c). Any materials to be submitted to participants in the Company Purchase Plan shall be subject to review and approval by Parent.

(d) Termination of 401(k) Plans. Effective as of no later than the day immediately preceding the Closing Date, each of the Company, its Subsidiaries and any ERISA Affiliate shall terminate any and all Company Employee Plans intended to include a Code Section 401(k) arrangement (each, a “401(k) Plan”) (unless Parent provides written notice to the Company that such 401(k) plans shall not be terminated). Unless Parent provides such written notice to the Company, no later than five Business Days prior to the Closing Date, the Company shall provide Parent with evidence that such Company Employee Plan(s) have been terminated (effective as of no later than the day immediately preceding the Closing Date) pursuant to resolutions of the Board of Directors of the Company, its Subsidiaries or such ERISA Affiliate, as the case may be. The form and substance of such resolutions shall be subject to review and approval of Parent. The Company also shall take such other actions in furtherance of terminating such Company Employee Plan(s) as Parent may reasonably require.

(e) Termination of Employees. The Company shall terminate the employment of each Employee not offered an employment position with Parent prior to the Closing Date, no later than immediately prior to the Effective Time. The Company may offer such Employees severance packages consistent with the Customary Severance Practices or as required pursuant to an existing agreement disclosed in the Company Disclosure Letter, provided that no severance payments or benefits shall be extended to any such Employee unless such Employee executes and delivers a form of release in form and substance acceptable to Parent.

(f) Change in Control Agreements. Immediately prior to the Effective Time, all amounts due for payments, acceleration of vesting of equity awards and extension of health benefits which may be due to employees or directors of the Company pursuant to an agreement set forth in Section 2.15(j) of the Company Disclosure Letter, as a result of the consummation of the Merger or the execution of this Agreement, shall be deemed to have been incurred by virtue of the consummation of the Merger. The Company shall treat any conditions other than the consummation of the Merger or the execution of this Agreement (such as actual or constructive termination of employment in connection with the Merger) as satisfied. It is acknowledged and agreed that, upon consummation of the Merger, all further conditions (such as actual or constructive termination of employment in connection with the Merger) set forth in any such agreement shall be deemed satisfied and that all such payments, vesting of equity awards and extension of health benefits shall be made without regard to the occurrence of any subsequent event; provided, (i) that cash payments may be made in lieu of health benefits, (ii) no such cash payments in lieu of health benefits shall be made to any Person who receives health benefits as an employee of Parent following the Effective Time and (iii) such payments, vesting acceleration and health benefits (or payment in lieu thereof) shall be conditioned upon receipt by Parent of a release and waiver of claims and agreement to the foregoing in form and substance reasonably satisfactory to Parent. The Company shall use commercially reasonable efforts to accomplish the foregoing, including obtaining such releases and agreements prior to the Effective Time.

5.10 Form S-8. Parent agrees to file a registration statement on Form S-8 for the shares of Parent Common Stock issuable with respect to assumed Company Options to the extent Form S-8 is available within 60 days after the Effective Time.

(a) Indemnity. From and after the Effective Time, Parent will, and will cause the Surviving Corporation to assume without further action by any of the parties, fulfill and honor in all respects the obligations of the Company pursuant to all rights to indemnification and exculpation from liabilities or acts or omissions occurring at or prior to the Effective Time (and rights for advancement of expenses) now existing in favor of the current or former directors or officers of the Company in its Articles of Incorporation or bylaws or any indemnification agreements between the Company and its directors and officers immediately prior to the Effective Time (the “Indemnified Parties”), subject to applicable law. The Articles of Incorporation and Bylaws of the Surviving Corporation will contain provisions with respect to exculpation and indemnification that are at least as favorable to the Indemnified Parties as those contained in the Articles of Incorporation and Bylaws of the Company as in effect on the date hereof, which provisions will not be amended, repealed or otherwise modified for a period of four years from the Effective Time in any manner that would adversely affect the rights thereunder of Indemnified Parties, unless such modification is required by law.

(b) Insurance. For a period of six years after the Effective Time, Parent will cause the Surviving Corporation to use best efforts to cause to be maintained directors’ and officers’ liability insurance maintained by the Company covering those persons who are covered by the Company’s directors’ and officers’ liability insurance policy as of the date hereof for events occurring prior to the Effective Time on terms comparable to those applicable to the current directors and officers of the Company for a period of six years; provided, however, that in no event will the Surviving Corporation be required to expend in excess of 150% of the annual premium currently paid by the Company for such coverage (and to the extent annual premium would exceed 150% of the annual premium currently paid by the Company for such coverage, the Surviving Corporation shall use commercially reasonable efforts to cause to be maintained the maximum amount of coverage as is available for such 150% of such annual premium) and provided further, however, that notwithstanding the foregoing, Parent may satisfy its obligations under this Section 5.11(b) by purchasing a “tail” policy under the Company’s existing directors’ and officers’ insurance policy which (i) has an effective term of six years from the Effective Time, (ii) covers those persons who are currently covered by the Company’s directors’ and officers’ insurance policy in effect as of the date hereof for actions and omissions occurring on or prior to the Effective Time, and (iii) contains terms and conditions that are comparable to the terms and conditions of the Company’s directors’ and officers’ insurance policy in effect as of the date hereof.

(c) Third–Party Beneficiaries. This Section 5.11 is intended to be for the benefit of, and shall be enforceable by the Indemnified Parties and their heirs and personal representatives and shall be binding on Parent and the Surviving Corporation and their respective successors and assigns. In the event Parent or the Surviving Corporation or its successor or assign (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each case, proper provision shall be made so that the successor and assign of Parent or the Surviving Corporation, as the case may be, honor the obligations set forth with respect to Parent or the Surviving Corporation, as the case may be, in this Section 5.11.

5.12 Company Rights Plan. The Company shall not redeem the Company Rights or amend or modify (including by delay of the “Distribution Date” thereunder) or terminate the Company Rights Plan prior to the Effective Time unless, and only to the extent that: (i) it is required to do so by order of a court of competent jurisdiction or (ii) its Board of Directors has concluded in good faith, after receipt of advice of its outside legal counsel, that, in light of a Change of Recommendation made in accordance with Section 5.3(d), the failure to effect such amendment, modification or termination is reasonably likely to result in a breach of its Board of Directors’ fiduciary obligations to its shareholders under applicable law.

5.13 Section 16 Matters. Prior to the Effective Time, the Company shall take all such steps as may be required (to the extent permitted under applicable law) to cause any dispositions of Company Common Stock

(including derivative securities with respect to Company Common Stock) resulting from the transactions contemplated by Article I of this Agreement by each individual who is subject to the reporting requirements of Section 16(a) of the Exchange Act with respect to the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

5.14 FIRPTA Compliance. On the Closing Date, the Company shall deliver to Parent a properly executed statement in a form reasonably acceptable to Parent for purposes of satisfying Parent’s obligations under Treasury Regulation Section 1.1445-2(c)(3).

5.15 Insurance Approval. The Company shall deliver to Parent at least 15 days prior to the Closing a letter in a form acceptable to Parent validly executed by an officer of the Company, which authorizes Parent’s insurance broker to act as the Company’s insurance broker of record with respect to all insurance policies held by the Company.

5.16 Negotiations Regarding Commercial Arrangement. Parent and the Company will negotiate in good faith to execute a commercially reasonable software license and development agreement within five business days of the date hereof, which agreement will provide: (a) Parent will pay the Company $500,000 upon each of the execution of the agreement and upon July 1, 2005, and will pay the Company $250,000 upon each of July 29, 2005, August 12, 2005, August 26, 2005 and September 10, 2005 so long as the Company is in material compliance with such agreement; (b) the Company shall provide non-recurring time-based engineering services and product resale licenses for the Company’s Secure Global Desktop product in consideration for such payments; and (c) Parent’s obligation to continue payments to the Company, and the Company’s obligation to provide engineering services under such agreement, will terminate upon the first to occur of the Effective Time or the termination of this Agreement in accordance with its terms.

7.4 Amendment. Subject to applicable law, this Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any time before or after approval of the Merger by the shareholders of the Company, provided, after approval of the Merger by the shareholders of the Company, no amendment shall be made which by law or in accordance with the rules of any relevant stock exchange or Nasdaq requires further approval by the shareholders of the Company without such further shareholder approval. This Agreement may not be amended except by execution of an instrument in writing signed on behalf of each of Parent, Merger Sub and the Company.

7.5 Extension; Waiver.

8.7 Other Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy.

8.11 Waiver of Jury Trial. EACH OF PARENT, MERGER SUB AND THE COMPANY HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF PARENT, MERGER SUB OR THE COMPANY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

Company Options:

You have requested our opinion (this “Opinion”) as to the fairness, from a financial point of view, to the stockholders of Tarantella, Inc., a California corporation (the “Company”), regarding the sale of their equity interest in the Company pursuant to the terms and subject to the conditions set forth in the draft Agreement and Plan of Merger, dated as of March 11, 2005 (“Merger Agreement”), by and among the Company, Sun Microsystems, Inc., a Delaware corporation (“Parent”), and Cha Cha Acquisition Corporation, Inc., a California corporation and wholly owned subsidiary of Parent (“Merger Sub”). As more fully described in the Merger Agreement, (i) the Company will be merged with and into the Merger Sub (the “Merger”), with the Company as the surviving company in the Merger, (ii) the Company will become a wholly owned subsidiary of Parent, and (iii) each outstanding share of Common Stock, without par value, of the Company will be converted into the right to receive $0.90 per share in cash (the “Proposed Transaction”).

(i) Reviewed certain documents provided to us with respect to the Proposed Transaction including the draft Merger Agreement described above;

(ii) Reviewed certain information, including historical and forecasted financial data, operational and business information relating to the earnings, cash flow, assets, capital structure and prospects of the Company;

(iii) Reviewed the Company’s historical Annual Reports on Form 10-K, its draft Form 10-Q for the period ended March 31, 2005 and other related financial information;

(iv) Conducted discussions of past and current business operations and future prospects of the Company with senior management of the Company, and reviewed financial projections prepared by the management of the Company;

(v) Reviewed, to the extent publicly available, financial terms of certain mergers and acquisitions involving companies operating in industries that we deem to be similar to the industry in which the Company operates;

(vi) Reviewed, to the extent publicly available, certain valuation and other financial information on select public companies deemed comparable to the Company;

(vii) Reviewed certain premiums paid in sale transactions deemed to be similar to the Proposed Transaction;

(viii) Reviewed the historical market prices and trading activity, to the extent publicly available, of the Company’s Common Stock;

(ix) Performed, based on projected financial and planning data provided to us by the Company’s senior management, a capitalization of earnings and discounted cash flow analysis with respect to the Company;

(x) Prepared such financial analyses and reviewed such other considerations as we deemed appropriate in order to render this Opinion.

In conducting our review and arriving at our opinion, we have, with your consent, assumed and relied upon the accuracy and completeness of all financial and other information discussed with or provided to us by the

Company or Parent, or which is publicly available. We have not undertaken any responsibility for the accuracy, completeness or reasonableness of, or to independently verify, such information. We have further relied on the assurances of management of the Company that they are not aware of any facts that would make any of the information reviewed by us inaccurate, incomplete or misleading in any respect. With respect to the forecasts regarding the future operating results of the Company provided to us, we have assumed, without independent verification or investigation, that such forecasts were prepared on bases reflecting the best currently available information, estimates and judgments of the management of the Company and that the assumptions underlying such forecasts are reasonable. We have not been engaged to assess the achievability of any projections or the assumptions on which they were based, and we express no view as to such projections or assumptions. In addition, we have not assumed any responsibility for any independent valuation or appraisal of the assets or liabilities of the Company, nor have we been furnished with any such valuation or appraisal. You have informed us, and we have assumed, that the Proposed Transaction will be consummated in accordance with the terms set forth in the draft Merger Agreement and in compliance with the applicable provisions of the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended, and all other applicable federal, state and local statutes, rules, regulations and ordinances.

We have assumed that the representations and warranties of each party in the draft Merger Agreement are true and correct, that each party will perform all covenants and agreements required to be performed by it under such agreement and that all conditions to the consummation of the Proposed Transaction will be satisfied without waiver thereof. We have further assumed that the final form of the Merger Agreement will be the same in all-material respects as the draft Merger Agreement. We have also assumed that all governmental, regulatory and other consents and approvals contemplated by the Merger Agreement will be obtained and that, in the course of obtaining any of those consents and approvals, no restrictions will be imposed or waivers made that would have an adverse effect on the contemplated benefits of the Proposed Transaction.

We were not requested to consider, and our opinion does not in any manner address, the relative merits of the Proposed Transaction as compared to any alternative business strategies that might exist for the Company or the effects of any other transaction in which the Company might engage. Our opinion is necessarily based on economic, market and other conditions as in effect on, and the information made available to us on, the date hereof. It should be understood that although subsequent developments may affect our opinion, we do not have any obligation to update, revise or reaffirm our opinion and we expressly disclaim any responsibility to do so.

We have provided certain investment banking and other services to the Company from time to time, including having acted as a placement agent in a private placement transaction pursuant to which the Company sold common stock and warrants resulting in gross proceeds of approximately $16,350,000 on February 23, 2004. In connection with this engagement, RCP is not entitled to any fees which are contingent upon the consummation of the Proposed Transaction. RCP will receive a fee of $150,000, of which $75,000 has already been paid. The remaining $75,000 consists of $25,000, due as of the presentation to the Board of Directors on May 9, 2005 and $50,000 due upon the delivery of this written Opinion. Furthermore, the Company has agreed to reimburse us for reasonable out of pocket expenses, and indemnify us against certain liabilities arising out of our engagement including the rendering of this Opinion and other matters, as more fully described in the engagement and indemnity agreement dated February 1, 2005. RCP is engaged by the Company to provide other advisory services which, if completed, may result in additional fees. In the ordinary course of our business, we may actively trade in the equity securities of the Company for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities.

This letter is solely for the information of the Board of Directors of the Company in its consideration of the Proposed Transaction and may not be relied on by any other person, used for any other purpose or reproduced,

disseminated, quoted or referred to at any time, in any manner or for any purpose without our prior written consent, except that this letter may be reproduced in its entirety, if required, in a proxy statement filed by the Company with the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended, provided that this letter is reproduced in such proxy statement in full and that any description of or reference to us or summary of this letter in such proxy statement will be in a form reasonably acceptable to us and our counsel. In furnishing this opinion, we do not admit that we are experts within the meaning of the term “experts” as used in the Securities Act and the rules and regulations thereunder, nor do we admit that this opinion constitutes a report or valuation within the meaning of Section 11 of the Securities Act.

RCP, as part of its investment banking business, is continually engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. RCP may provide additional investment banking services to the Company in the future. RCP provides a full range of financial advisory and securities services and, in the course of its normal trading activities, may from time to time effect transactions and hold securities, including derivatives, of the Company for its own account and for the accounts of customers.

Based upon and subject to the foregoing, including the various assumptions and limitations set forth herein, we are of the opinion that as of the date hereof, the consideration to be paid by the Parent pursuant to the Proposed Transaction is fair, from a financial point of view, to the holders of the outstanding shares of Company Common Stock.

SECTION 1300. REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES; CORPORATE PURCHASE AT FAIR MARKET VALUE; DEFINITIONS.

(a) If the approval of the outstanding shares (Section 152) of a corporation is required for a reorganization under subdivisions (a) and (b) or subdivision (e) or (f) of Section 1201, each shareholder of the corporation entitled to vote on the transaction and each shareholder of a subsidiary corporation in a short-form merger may, by complying with this chapter, require the corporation in which the shareholder holds shares to purchase for cash at their fair market value the shares owned by the shareholder which are dissenting shares as defined in subdivision (b). The fair market value shall be determined as of the day before the first announcement of the terms of the proposed reorganization or short-form merger, excluding any appreciation or depreciation in consequence of the proposed action, but adjusted for any stock split, reverse stock split, or share dividend which becomes effective thereafter.

(b) As used in this chapter, “dissenting shares” means shares which come within all of the following descriptions:

(1) Which were not immediately prior to the reorganization or short-form merger either (A) listed on any national securities exchange certified by the Commissioner of Corporations under subdivision (o) of Section 25100 or (B) listed on the National Market System of the NASDAQ Stock Market, and the notice of meeting of shareholders to act upon the reorganization summarizes this section and Sections 1301, 1302, 1303 and 1304; provided, however, that this provision does not apply to any shares with respect to which there exists any restriction on transfer imposed by the corporation or by any law or regulation; and provided, further, that this provision does not apply to any class of shares described in subparagraph (A) or (B) if demands for payment are filed with respect to 5 percent or more of the outstanding shares of that class.

(2) Which were outstanding on the date for the determination of shareholders entitled to vote on the reorganization and (A) were not voted in favor of the reorganization or, (B) if described in subparagraph (A) or (B) of paragraph (1) (without regard to the provisions in that paragraph), were voted against the reorganization, or which were held of record on the effective date of a short-form merger; provided, however, that subparagraph (A) rather than subparagraph (B) of this paragraph applies in any case where the approval required by Section 1201 is sought by written consent rather than at a meeting.

(3) Which the dissenting shareholder has demanded that the corporation purchase at their fair market value, in accordance with Section 1301.

(4) Which the dissenting shareholder has submitted for endorsement, in accordance with Section 1302.

(c) As used in this chapter, “dissenting shareholder” means the recordholder of dissenting shares and includes a transferee of record.

SECTION 1301. NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND FOR PURCHASE; TIME; CONSENTS.

(a) If, in the case of a reorganization, any shareholders of a corporation have a right under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, to require the corporation to purchase their shares for cash, such corporation shall mail to each such shareholder a notice of the approval of the reorganization by its outstanding shares (Section 152) within 10 days after the date of such approval, accompanied by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of the price determined by the corporation to represent the fair market value of the dissenting shares, and a brief description of the procedure to be followed if the shareholder desires to exercise the shareholder’s right under such sections. The

statement of price constitutes an offer by the corporation to purchase at the price stated any dissenting shares as defined in subdivision (b) of Section 1300, unless they lose their status as dissenting shares under Section 1309.

(b) Any shareholder who has a right to require the corporation to purchase the shareholder’s shares for cash under Section 1300, subject to compliance with paragraphs (3) and (4) of subdivision (b) thereof, and who desires the corporation to purchase such shares shall make written demand upon the corporation for the purchase of such shares and payment to the shareholder in cash of their fair market value. The demand is not effective for any purpose unless it is received by the corporation or any transfer agent thereof (1) in the case of shares described in clause (i) or (ii) of paragraph (1) of subdivision (b) of Section 1300 (without regard to the provisos in that paragraph), not later than the date of the shareholders’ meeting to vote upon the reorganization, or (2) in any other case within 30 days after the date on which the notice of the approval by the outstanding shares pursuant to subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder.

(c) The demand shall state the number and class of the shares held of record by the shareholder which the shareholder demands that the corporation purchase and shall contain a statement of what such shareholder claims to be the fair market value of those shares as of the day before the announcement of the proposed reorganization or short-form merger. The statement of fair market value constitutes an offer by the shareholder to sell the shares at such price.

SECTION 1302. SUBMISSION OF SHARE CERTIFICATES FOR ENDORSEMENT; UNCERTIFICATED SECURITIES.

Within 30 days after the date on which notice of the approval by the outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, the shareholder shall submit to the corporation at its principal office or at the office of any transfer agent thereof, (a) if the shares are certificated securities, the shareholder’s certificates representing any shares which the shareholder demands that the corporation purchase, to be stamped or endorsed with a statement that the shares are dissenting shares or to be exchanged for certificates of appropriate denomination so stamped or endorsed or (b) if the shares are uncertificated securities, written notice of the number of shares which the shareholder demands that the corporation purchase. Upon subsequent transfers of the dissenting shares on the books of the corporation, the new certificates, initial transaction statement, and other written statements issued therefor shall bear a like statement, together with the name of the original dissenting holder of the shares.

SECTION 1303. PAYMENT OF AGREED PRICE WITH INTEREST; AGREEMENT FIXING FAIR MARKET VALUE; FILING; TIME OF PAYMENT.

(a) If the corporation and the shareholder agree that the shares are dissenting shares and agree upon the price of the shares, the dissenting shareholder is entitled to the agreed price with interest thereon at the legal rate on judgments from the date of the agreement. Any agreements fixing the fair market value of any dissenting shares as between the corporation and the holders thereof shall be filed with the secretary of the corporation.

(b) Subject to the provisions of Section 1306, payment of the fair market value of dissenting shares shall be made within 30 days after the amount thereof has been agreed or within 30 days after any statutory or contractual conditions to the reorganization are satisfied, whichever is later, and in the case of certificated securities, subject to surrender of the certificates therefor, unless provided otherwise by agreement.

SECTION 1304. ACTION TO DETERMINE WHETHER SHARES ARE DISSENTING SHARES OR FAIR MARKET VALUE; LIMITATION; JOINDER; CONSOLIDATION; DETERMINATION OF ISSUES; APPOINTMENT OF APPRAISERS.

(a) If the corporation denies that the shares are dissenting shares, or the corporation and the shareholder fail to agree upon the fair market value of the shares, then the shareholder demanding purchase of such shares as

dissenting shares or any interested corporation, within six months after the date on which notice of the approval by the outstanding shares (Section 152) or notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but not thereafter, may file a complaint in the superior court of the proper county praying the court to determine whether the shares are dissenting shares or the fair market value of the dissenting shares or both or may intervene in any action pending on such a complaint.

(b) Two or more dissenting shareholders may join as plaintiffs or be joined as defendants in any such action and two or more such actions may be consolidated.

(c) On the trial of the action, the court shall determine the issues. If the status of the shares as dissenting shares is in issue, the court shall first determine that issue. If the fair market value of the dissenting shares is in issue, the court shall determine, or shall appoint one or more impartial appraisers to determine, the fair market value of the shares.

SECTION 1305. REPORT OF APPRAISERS; CONFIRMATION; DETERMINATION BY COURT; JUDGMENT; PAYMENT; APPEAL; COSTS.

(a) If the court appoints an appraiser or appraisers, they shall proceed forthwith to determine the fair market value per share. Within the time fixed by the court, the appraisers, or a majority of them, shall make and file a report in the office of the clerk of the court. Thereupon, on the motion of any party, the report shall be submitted to the court and considered on such evidence as the court considers relevant. If the court finds the report reasonable, the court may confirm it.

(b) If a majority of the appraisers appointed fail to make and file a report within 10 days from the date of their appointment or within such further time as may be allowed by the court or the report is not confirmed by the court, the court shall determine the fair market value of the dissenting shares.

(c) Subject to the provisions of Section 1306, judgment shall be rendered against the corporation for payment of an amount equal to the fair market value of each dissenting share multiplied by the number of dissenting shares which any dissenting shareholder who is a party, or who has intervened, is entitled to require the corporation to purchase, with interest thereon at the legal rate from the date on which judgment was entered.

(d) Any such judgment shall be payable forthwith with respect to uncertificated securities and, with respect to certificated securities, only upon the endorsement and delivery to the corporation of the certificates for the shares described in the judgment. Any party may appeal from the judgment.

(e) The costs of the action, including reasonable compensation to the appraisers to be fixed by the court, shall be assessed or apportioned as the court considers equitable, but, if the appraisal exceeds the price offered by the corporation, the corporation shall pay the costs (including in the discretion of the court attorneys’ fees, fees of expert witnesses and interest at the legal rate on judgments from the date of compliance with Sections 1300, 1301 and 1302 if the value awarded by the court for the shares is more than 125 percent of the price offered by the corporation under subdivision (a) of Section 1301).

To the extent that the provisions of Chapter 5 prevent the payment to any holders of dissenting shares of their fair market value, they shall become creditors of the corporation for the amount thereof together with interest at the legal rate on judgments until the date of payment, but subordinate to all other creditors in any liquidation proceeding, such debt to be payable when permissible under the provisions of Chapter 5.

Cash dividends declared and paid by the corporation upon the dissenting shares after the date of approval of the reorganization by the outstanding shares (Section 152) and prior to payment for the shares by the corporation shall be credited against the total amount to be paid by the corporation therefor.

SECTION 1308. RIGHTS OF DISSENTING SHAREHOLDERS PENDING VALUATION; WITHDRAWAL OF DEMAND FOR PAYMENT.

Except as expressly limited in this chapter, holders of dissenting shares continue to have all the rights and privileges incident to their shares, until the fair market value of their shares is agreed upon or determined. A dissenting shareholder may not withdraw a demand for payment unless the corporation consents thereto.

Dissenting shares lose their status as dissenting shares and the holders thereof cease to be dissenting shareholders and cease to be entitled to require the corporation to purchase their shares upon the happening of any of the following:

(a) The corporation abandons the reorganization. Upon abandonment of the reorganization, the corporation shall pay on demand to any dissenting shareholder who has initiated proceedings in good faith under this chapter all necessary expenses incurred in such proceedings and reasonable attorneys’ fees.

(b) The shares are transferred prior to their submission for endorsement in accordance with Section 1302 or are surrendered for conversion into shares of another class in accordance with the articles.

(c) The dissenting shareholder and the corporation do not agree upon the status of the shares as dissenting shares or upon the purchase price of the shares, and neither files a complaint or intervenes in a pending action as provided in Section 1304, within six months after the date on which notice of the approval by the outstanding shares or notice pursuant to subdivision (i) of Section 1110 was mailed to the shareholder.

(d) The dissenting shareholder, with the consent of the corporation, withdraws the shareholder’s demand for purchase of the dissenting shares.

SECTION 1310. SUSPENSION OF RIGHT TO COMPENSATION OR VALUATION PROCEEDINGS; LITIGATION OF SHAREHOLDERS’ APPROVAL.

If litigation is instituted to test the sufficiency or regularity of the votes of the shareholders in authorizing a reorganization, any proceedings under Sections 1304 and 1305 shall be suspended until final determination of such litigation.

This chapter, except Section 1312, does not apply to classes of shares whose terms and provisions specifically set forth the amount to be paid in respect to such shares in the event of a reorganization or merger.

SECTION 1312. RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND MERGER OR REORGANIZATION; RESTRAINING ORDER OR INJUNCTION; CONDITIONS.

(a) No shareholder of a corporation who has a right under this chapter to demand payment of cash for the shares held by the shareholder shall have any right at law or in equity to attack the validity of the reorganization or short-form merger, or to have the reorganization or short-form merger set aside or rescinded, except in an action to test whether the number of shares required to authorize or approve the reorganization have been legally voted in favor thereof; but any holder of shares of a class whose terms and provisions specifically set forth the amount to be paid in respect to them in the event of a reorganization or short-form merger is entitled to payment in accordance with those terms and provisions or, if the principal terms of the reorganization are approved pursuant to subdivision (b) of Section 1202, is entitled to payment in accordance with the terms and provisions of the approved reorganization.

(b) If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, subdivision (a) shall not apply to any shareholder of such party who has not demanded payment of cash for such shareholder’s shares pursuant to this chapter; but if the shareholder institutes any action to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, the shareholder shall not thereafter have any right to demand payment of cash for the shareholder’s shares pursuant to this chapter. The court in any action attacking the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded shall not restrain or enjoin the consummation of the transaction except upon 10 days’ prior notice to the corporation and upon a determination by the court that clearly no other remedy will adequately protect the complaining shareholder or the class of shareholders of which such shareholder is a member.

(c) If one of the parties to a reorganization or short-form merger is directly or indirectly controlled by, or under common control with, another party to the reorganization or short-form merger, in any action to attack the validity of the reorganization or short-form merger or to have the reorganization or short-form merger set aside or rescinded, (1) a party to a reorganization or short-form merger which controls another party to the reorganization or short-form merger shall have the burden of proving that the transaction is just and reasonable as to the shareholders of the controlled party, and (2) a person who controls two or more parties to a reorganization shall have the burden of proving that the transaction is just and reasonable as to the shareholders of any party so controlled.

SECTION 1313. CONVERSIONS DEEMED TO CONSTITUTE A REORGANIZATION; APPLICATION OF CHAPTER.

A conversion pursuant to Chapter 11.5 (commencing with Section 1150) shall be deemed to constitute a reorganization for purposes of applying the provisions of this chapter, in accordance with and to the extent provided in Section 1159.

The undersigned shareholder of Tarantella, Inc. hereby acknowledges receipt of the Notice of Special Meeting of Shareholders and Proxy Statement, each dated June 10, 2005, and hereby appoints Francis E.
