	Q:	What is the proposed Merger?
	A:	Under the terms of the Agreement and Plan of Merger dated as of June 2, 2005 among Sun Microsystems, Inc. (“Sun”), Stanford Acquisition Corporation, a direct wholly-owned subsidiary of Sun (“Merger Sub”), and Storage Technology Corporation (“StorageTek”), referred to in this proxy statement as the merger agreement, Merger Sub will be merged with and into StorageTek with StorageTek emerging as the surviving corporation and a wholly-owned subsidiary of Sun. The merger agreement is attached to this proxy statement as Annex A. We encourage you to read it carefully.
	Q:	What will I receive in the merger?
	A:	Upon completion of the merger, you will be entitled to receive $37 in cash, without interest, in exchange for each share of StorageTek common stock, par value $0.10 per share, that you own.
	Q:	What are the United States federal income tax consequences of the merger?
	A:	The receipt of cash for shares pursuant to the merger will be a taxable transaction for United States federal income tax purposes. In general, a stockholder who receives cash in exchange for shares pursuant to the merger will recognize gain or loss for United States federal income tax purposes equal to the difference, if any, between the amount of cash received and the stockholder’s adjusted tax basis in the shares exchanged for cash pursuant to the merger. Because the tax consequences of the merger are complex and may vary depending on your particular circumstances, we recommend that you consult your tax advisor concerning the federal (and any state, local or foreign) tax consequences to you of the merger.
	Q:	What is the vote required to approve the merger agreement?
	A:	Approval of the merger agreement requires the affirmative vote of a majority of the outstanding shares of StorageTek common stock. This means that the affirmative vote of at least [                    ] shares of our common stock is required for adoption of the merger agreement.
	Q:	Is our board of directors recommending that I vote for the merger agreement?
	A:	Yes. After considering a number of factors, your board of directors unanimously believes that the terms of the merger agreement are fair to and in the best interests of StorageTek and our stockholders. Your board of directors unanimously recommends that you vote FOR approval of the merger and adoption and approval of the merger agreement.
	Q:	Why did the directors enter into the voting agreements?
	A:	In order to induce Sun to execute the merger agreement, the directors, each in their capacity as a stockholder of StorageTek common stock, agreed to vote the StorageTek common stock they own FOR the merger. The execution and delivery of the voting agreements was a material condition to Sun’s willingness to enter into the merger agreement. As of [                    ], 2005, the directors own an aggregate of [                    ]% of the outstanding shares of StorageTek common stock.
	Q:	When do you expect to complete the merger?
	A:	We currently expect to complete the merger in the third calendar quarter of 2005, as quickly as possible after the special meeting and after all the conditions to the merger are satisfied or

		waived, including expiration or termination of the waiting periods under the antitrust laws of the United States and the European Union and other applicable jurisdictions.
	Q:	What do I need to do now?
	A:	We urge you to read this proxy statement carefully, including its annexes, consider how the merger would affect you as a stockholder and then vote. After you read this proxy statement, you should provide voting instructions as described below.
	Q:	How do I vote?
	A:	If you hold a stock certificate in your name for StorageTek’s common stock, you are the owner of record. If you attend the meeting, you may vote in person. If you want to vote by proxy, there are three ways you may vote, each of which is valid under Delaware law, our state of incorporation:

	1.	Access the Internet address on the proxy card and follow the instructions at that site;
	2.	Call the toll-free telephone number listed in the voting instructions attached to the proxy card and follow the telephone prompts; OR
	3.	Complete, sign, date and return the enclosed proxy card.

	Q:	If my broker holds my shares in “street name,” will my broker vote my shares for me?
	A:	If your shares of StorageTek common stock are held in the name of a broker or financial institution, you are a beneficial owner and the broker or the financial institution holding your shares is the record holder. This is often referred to as being held in “street name.” You must follow the voting directions given by the broker or financial institution. If you hold shares in street name and you intend to vote at the special meeting, you must bring an executed Power of Attorney or proxy in your name that has been signed by the record holder. Contact your broker or financial institution for this information.
	Q:	What if I want to change my vote after I have voted?
	A:	You may revoke your proxy or change your vote at any time before the final vote at the meeting. If you are the owner of record, you may do this by:

	1.	Giving written notice of revocation to the Corporate Secretary, Storage Technology Corporation, One StorageTek Drive, Louisville, Colorado 80028-4309;
	2.	Signing another valid proxy bearing a later date;
	3.	Voting at a later date by telephone or by using the Internet; OR
	4.	Voting in person at the meeting.

	If you hold stock in street name, you must contact your broker or financial institution for information on how to revoke your proxy or change your vote.

	Q:	What happens if I do not send in my proxy, if I do not instruct my broker to vote my shares or if I abstain from voting?
	A:	If you do not send in your proxy, do not instruct your broker to vote your shares, or if you abstain from voting, it will have the same effect as a vote AGAINST approval of the merger, and adoption and approval of the merger agreement.
	Q:	What if the merger is not completed?
	A:	If the merger is not completed, both companies will continue to operate as independent companies. As further described under “Expenses and Termination Fee” on page [     ],

		StorageTek may be required to pay Sun a termination fee if the merger is not completed for certain reasons.
	Q:	Am I entitled to appraisal rights?
	A:	Yes. Under the Delaware General Corporations Law (“DGCL”), record holders of StorageTek common stock who follow the procedures set forth in Section 262 of the DGCL will be entitled to have their shares appraised by the Court of Chancery of the State of Delaware and to receive payment of the fair value of such shares together with a fair rate of interest, if any, as determined by such court. The fair value as determined by the Delaware court is exclusive of any element of value arising from the accomplishment or expectation of the merger.
	Q:	Should I send in my StorageTek stock certificates now?
	A:	No. After the merger is completed, you will receive written instructions for exchanging your shares of StorageTek common stock for the merger consideration of $37 in cash, without interest, for each share of your StorageTek common stock.
	Q:	Where can I find more information about StorageTek and Sun?
	A:	Storage Technology Corporation and Sun Microsystems, Inc. file periodic reports and other information with the Securities and Exchange Commission (“SEC”).

	Factors Relating to the Transaction Generally:

	•	StorageTek has experienced increased competition in recent years as a result of several factors including industry consolidation, trends toward disk-to-disk data back-up, data center consolidation and outsourcing, and competition in tape and open systems virtual tape storage.
	•	StorageTek’s sales force and distribution infrastructure is smaller than the sales forces and distribution infrastructures of most of our competitors. This results in StorageTek having a disproportionately lower share of influence in the storage market and specifically on the ability to influence customers’ perceptions regarding the comparative benefits of tape products versus disk products.
	•	As a result of industry consolidation and increased competition, StorageTek has experienced increased pricing pressures and other competitive pressures in recent years which require that StorageTek offer better products and have a stronger product pipeline than our competitors and introduce new products to the market faster than our competitors.
	•	In recent years customers have tended to reduce the number of information technology vendors and reduce information technology spending and utility and outsourcing contracts are gaining greater importance in the industry.
	•	Our major competitors have increasingly used their size and portfolio breadth as leverage for competitive advantage in the market today.
	•	The environment for acquisitions in the data storage industry is very competitive such that StorageTek currently represents a valuable strategic opportunity for potential buyers such as Sun, given our distinctive, diversified portfolio of products and services, our long standing experience in the data center market, and our broad and diversified customer base. Accordingly, our board concluded that this was a favorable time to undertake a sale of the company.

	Factors Relating to the Specific Terms of our Merger Agreement with Sun:

	•	The merger consideration of $37 per share to be received by our stockholders represents a substantial premium to the historic trading prices of StorageTek common stock. The merger consideration represents a 14.6% premium over the closing price of StorageTek common stock on May 31, 2005 (the trading day immediately preceding the day prior to the date of execution of the merger agreement), a 17.3% premium over the closing price of StorageTek common stock on May 24, and a 30.7% premium over the closing price of StorageTek common stock on May 3.
	•	The merger consideration consists solely of cash, which provides certainty of value to our stockholders.
	•	Sun has, and has represented in the merger agreement that it has, adequate capital resources to pay the merger consideration.
	•	The merger agreement, subject to the limitations and requirements contained in the agreement, allows our board to furnish information to and conduct negotiations with a third party in certain circumstances and, upon the payment to Sun of a termination fee of $133 million, to terminate the merger agreement to accept a superior offer.
	•	The merger agreement provides reasonable certainty of consummation, because it includes limited conditions to Sun’s obligation to complete the merger, including:

	•	Sun is generally obligated to close the merger notwithstanding any breaches of StorageTek’s representations and warranties, unless those breaches would have a material adverse effect on StorageTek; and
	•	Although Sun has the right not to complete the merger if changes, among other things, occur that have a material adverse effect on StorageTek as a whole, the effects of changes in general

18

---

Table of Contents

		financial market and industry conditions to the extent such changes do not disproportionately affect StorageTek, are excluded in determining whether any material adverse effect has occurred.

	•	The merger must be approved and the merger agreement must be adopted and approved by a vote of a majority of our outstanding shares of common stock.
	•	Our board considered the presentation of Evercore on June 1, 2005 and its oral opinion, which opinion was subsequently confirmed in writing on June 2, 2005, to the effect that as of such date and based upon and subject to the factors and assumptions set forth in its opinion, the $37 in cash per share of StorageTek common stock to be received by the holders of StorageTek common stock pursuant to the merger agreement was fair, from a financial point of view as of the date of such opinion, to such holders. The full text of Evercore’s written opinion is attached to this proxy statement as Annex B and is incorporated by reference into this proxy statement. We urge you to read this opinion carefully in its entirety for a description of the assumptions made, procedures followed, matters considered and limitations on the review undertaken in connection with the opinion.
	•	Our board considered the general terms and conditions of the merger agreement, including the parties’ representations, warranties and covenants, the conditions to their respective obligations as well as the likelihood of the consummation of the merger, the proposed transaction structure, the termination provisions of the agreement and our board’s evaluation of the likely time period necessary to close the transaction.

	Potential Negative Factors Relating to the Transaction:

	•	The merger agreement precludes us from actively soliciting alternative proposals.
	•	We are obligated to pay to Sun a termination fee of $133 million plus reimbursement of Sun’s expenses if we terminate the merger agreement under certain circumstances. It is possible that these provisions could discourage a competing proposal to acquire us or reduce the price in an alternative transaction.
	•	The merger consideration consists solely of cash and will be taxable to our stockholders for U.S. federal income tax purposes. In addition, because our stockholders are receiving cash for their stock, they will not participate after the closing in any future growth or the benefits of synergies resulting from the merger.
	•	Certain of our directors and officers may have conflicts of interest in connection with the merger, as they may receive certain benefits that are different from, and in addition to, those of our other stockholders. See “—Interests of Certain Persons in the Merger.”
	•	We may incur significant risks and costs if the merger does not close, including the diversion of management and employee attention during the period after the signing of the merger agreement, potential employee attrition and the potential effect on our business and customer relations. In that regard, under the merger agreement, we must conduct our business in the ordinary course and we are subject to a variety of other restrictions on the conduct of our business prior to completion of the merger or termination of the merger agreement, which may delay or prevent us from undertaking business opportunities that may arise.

The dollar value of accelerated stock options is calculated by subtracting the exercise price from $37.00 per share and multiplying this amount by the total number of option shares that may be accelerated. The dollar value of accelerated restricted stock is calculated by multiplying the number of shares held by $37.00 less, if applicable, any cash that the officer paid for the restricted stock. The actual value of stock options and restricted stock that are converted to Sun stock options and restricted stock is dependent upon the market value of Sun stock at the time the stock options are exercised or the restricted stock vests.
