On October 4, 2000, Mike Cannon and Michael Brown utilized the following script in connection with their discussion of the merger during their conference call with analysts. ANALYST/PRESS CONFERENCE CALL SCRIPT MAXTOR ANNOUNCEMENT Oct. 4, 2000 MIKE CANNON Good morning, and thank you for joining us. Today, Maxtor Corporation and Quantum Corporation jointly announced a definitive agreement to combine Quantum's Hard Disk Drive Group with Maxtor in a $2 billion merger that will create the world's leading disk drive company. On the call today, I'm joined by Michael Brown, the chairman and CEO of Quantum; Rick Clemmer, CFO of Quantum; and Paul Tufano, CFO of Maxtor. All four of us will be available to comment individually when we open the call for questions in a few minutes. First though, we'll start with some opening remarks. I'll begin by summarizing the terms of the transaction, then Michael Brown will outline a description of the combined company and talk through some of the thinking leading up to this merger. Finally, I'll go through some of the key strategies that the new company will pursue and comment on several of the opportunities we believe will drive both near- and long-term growth. This merger transaction is expected to be tax-free to Quantum, Maxtor and each company's stockholders. The merged company will be called Maxtor Corp., and I will serve as the CEO, with Paul Tufano as CFO. The Board of Directors will consist of myself and Michael Brown, as well as the directors who make up the current Maxtor board. Quantum HDD stockholders will receive 1.52 Maxtor shares for each Quantum HDD share held. Upon approval of the transaction by Quantum and Maxtor stockholders, and assuming that all regulatory approvals and other customary closing conditions are satisfied, we expect to complete the merger in early calendar 2001. Upon completion of the transaction, we expect to incur a special restructuring charge and other one-time expenses of between $100 and $180 million. When the merger is consummated the new company will, at inception, have combined annual sales of approximately $6 billion, combined market capitalization of approximately $2 billion and a combined ship rate of more than 50 million drives annually. The new company will also have one of the strongest balance sheets of any publicly held disk drive company. Now I'd like to turn the call over to Michael Brown. Michael. MICHAEL BROWN Thank you Mike. Good morning, and thanks to all of you for joining us on such short notice. First I'd like to express how enthusiastic I am about this merger and about the opportunity it represents for the new combined enterprise. It's important to note that Quantum's DLT & Storage Systems Group, or DSSG, is not directly involved in this transaction. Upon completion of the merger between Maxtor and Quantum HDD, the Quantum DSS business will operate as a separate, standalone company, which will be known as Quantum Corporation. Shares of the Quantum DSS tracking stock will then be re-named as Quantum Corp. common stock. Additionally, DSS will incur a special accounting charge upon the close of the transaction related to the conversion of Quantum employee stock options. The new hard disk drive company we plan to create will bring together the solid and complementary positions that both companies have achieved in the highly competitive hard drive industry. Quantum and Maxtor each have track records of outstanding operational execution, which includes high-quality products, strong customer support, industry-leading asset management and excellent time-to-market. After completion of the merger, the combined company will be positioned as a time-to-market leader for the past 14 generations of desktop products, and will be an industry leader in asset velocity for the two years. Looking at market position, the new company will also hold leading positions within key segments and sales channels, including in the desktop, consumer electronics and Intel-based server spaces, as well as with all of the top 10 PC OEMs and in the retail channel for hard drives. However, in spite of the solid operational performance that both businesses have consistently demonstrated, the ability of each to achieve the growth and financial returns we would like has been constrained by industry dynamics that neither company has been able to overcome on its own. It's clear to us that through a combination of the two businesses, we have the opportunity to improve the way we do business and, ultimately, to provide greater value to our customers by becoming a more competitive force within the industry. We can achieve this by cutting costs, expanding into more marketplaces, and offering a broader range of competitively priced, value-added products. This, essentially, is the single biggest objective of the merger: to create a stronger disk drive company that will be able to leverage its combined resources in order to serve a broader range of diverse customer needs. In achieving this goal, our expectation is that we will also return greater value to the stockholders of the new company than either company could return on its own. In a moment, Mike Cannon is going to talk more specifically about the strategies we'll use to meet this objective. Let me close by saying that in joining two companies the caliber of Quantum HDD and Maxtor, we believe the new business will become the strongest, most competitive and most broadly diversified supplier of hard disk drives and disk-based systems in this dynamic and important industry. And we're very enthused that, upon the completion of this merger, the company that will result will then become the premier vehicle for investment in this growing industry. Now I'll turn the call over to Mike Cannon. MIKE CANNON Thank you. As Michael Brown just said, this merger will give us the opportunity to create a company with unparalleled benefits to customers. Maxtor and Quantum HDD together have a complementary range of products that extends from drives for entry-level PC customers through more performance-oriented high-capacity desktop drives. The company will also offer drives for the rapidly emerging consumer electronics market, drives for higher-margin opportunities in the Intel-based server segment, and a family of network attached storage appliances. In addition to providing the industry's broadest range of hard disk drive products, the combined company will also build on the strengths in technology development, manufacturing flexibility, quality and customer support that we share. Now I'll summarize some of the key strategies that the new company will pursue, including the current and emerging opportunities that we plan to target for strategic development. First, our strategy will be to maintain our leadership position in the desktop drive business. Together, the two companies will have a solid position in the desktop PC area and, therefore, the opportunity to build a more efficient and more profitable business in other segments than either company could have on its own. The second strategy will be to expand rapidly into the highest-growth segments of the disk drive industry which offer higher potential for profit. With the combined engineering resources of the two companies, we will be able to sustain investments in Intel server-class drives, consumer electronics drives, and smaller form factor drives serving current and emerging portable applications. In addition to HDD devices, we will also participate in areas where there is a higher level of value, including the network attached storage market through the MaxAttach family of server appliances. Third, the reduction of duplicative expenses, particularly in the areas of SG&A is, in and of itself, a strategy that can have significant impact on the value that we want to create for both customers and stockholders. We estimate that within two years of combining operations, the new company can reduce its operating costs by $120 to $200 million per year. These reductions will come primarily from the elimination of duplicative expenses in overhead structure. This improvement in the company's financial structure will allow us to continue to offer better value for customers and, even more importantly, to generate the profits necessary to fund expanded research and development in new areas to provide even more value to our customers. As a result of these improvements, we expect the transaction to become accretive to earnings in early 2002. Finally, the last key strategy I'll mention is around our approach to manufacturing the more than 50 million drives we expect to produce in the first year alone. The combined company will have the industry's best manufacturing capability. We will continue Quantum's 16-year, strategic manufacturing relationship with MKE, and we will also continue to utilize Maxtor's manufacturing capability in Singapore. We believe that the combination of MKE's renowned automated, high-volume manufacturing with Maxtor's cell-based, highly flexible approach is an outstanding combination. One of the key advantages of this business combination is the ability to benefit from the operating leverage of the existing Quantum-MKE relationship. Because MKE invests in the property, plant and equipment for manufacturing - as well as raw materials and work-in-process inventories - Quantum is able to achieve the best return on invested capital in the industry. As the growth of the Internet and the proliferation of digital content continues driving demand for storage, analysts are predicting continued, strong growth of over 15 percent in the overall hard disk drive industry through 2003. Within that, two of the fastest-growing areas are consumer electronics drives and Intel-server class drives, which are expected to grow at compounded annual rates of 200 percent and 32 percent, respectively, through the year 2003. In the area of network attached storage appliances, it is expected that revenue in the workgroup segment - where the MaxAttach server appliance is targeted - will grow to $2.5 billion by 2002. With the solid positions the new company will have in each of these high-growth areas, we will be uniquely positioned to serve a broad range of storage requirements, increasing the efficiency of the supplier base for our customers. We expect the new organization to be highly growth-oriented and profitability-driven, with a strong commitment to R&D investment, on-time delivery of leading-edge products, and responsiveness to customer needs. Before we open the call for questions, I'd like to summarize with a couple of closing remarks. To reiterate, the reason we are merging Maxtor and Quantum HDD is to create a substantially stronger company that will be well positioned to engage in the explosive growth of storage in a number of different areas. The new Maxtor will have the broadest range of desktop products in the industry; we will have a fast growing SCSI product family for Intel-based servers; we will have a leading position in consumer electronics applications utilizing disk drives; and we will continue to expand our presence in the rapidly-growing network attached storage area with our award-winning MaxAttach family of server appliances. The combined company will have the people, intellectual property and financial resources to ensure we are able to make the investments necessary to grow in our current markets and to invest in future growth opportunities in storage at both the device and subsystem level. Thank you for joining us today. Now I'll open the call for questions. Q&A B.
