Forward Looking Statement
This presentation contains forward-looking statements that involve risks and uncertainties, including, but not limited to, the development and adoption of a
new storage architecture and the potential introduction of products based on this architecture. Forward-looking statements should not be read as a guarantee
of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved, if
at all. Forward-looking statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those
expressed in or suggested by the forward-looking statements.
Additional key risks and uncertainties include the impact of continued uncertainty and volatility in global economic conditions; actions by competitors,
business conditions and growth in the various hard drive segments. More information about the other risks and uncertainties that could affect our business
are listed in our filings with the Securities and Exchange Commission (the “SEC”) and available on the SEC’s website at www.sec.gov, including our
Quarterly Report on Form 10-Q filed with the SEC on May 5, 2014, to which your attention is directed. We do not undertake any obligation to publicly update
or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as otherwise required by law.
This presentation contains financial measures defined as non-GAAP by the SEC. We believe that certain non-GAAP financial measures, when presented in
conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful because that information is an appropriate measure for
evaluating our operating performance. Non-GAAP information is used to evaluate business performance and management's effectiveness. These measures
should be considered in addition to, not as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Non-GAAP
financial measures may not be calculated in the same manner by all companies and therefore may not be comparable.

Capacity & Trademark Statements
One gigabyte (GB) is equal to one billion bytes, one terabyte (TB) equals 1,000GB (one trillion bytes), and one petabyte (PB) equals
1,000TB (one quadrillion bytes) when referring to hard drive or solid state drive capacity. Accessible capacity will vary from the stated
capacity due to formatting and partitioning of the drive, the computer’s operating system, and other factors.
