Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These statements are based on management’s current expectations and beliefs and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. The forward-looking statements contained in this presentation include statements about future financial and operating results, economic growth rates, industry and market conditions, potential synergies and cost savings, the ability to drive growth and expand customer and partner relationships, changes in gross margins, revenues and operating expenses, manufacturing yields or operations, product development initiatives, design win conversion and other such statements. These statements are not guarantees of future performance, involve risks, uncertainties and assumptions that are difficult to predict, and are based upon assumptions as to future events that may not prove accurate. Therefore, actual outcomes and results may differ materially from what is expressed herein. In any forward-looking statement in which the Company expresses an expectation or belief as to future results, such expectation or belief is expressed in good faith and believed to have a reasonable basis, but there can be no assurance that the statement or expectation or belief will result or be achieved or accomplished. Information concerning risk factors are detailed in the Company's SEC reports, including the Annual Report on Form 10-K for the year ended April 1, 2012 and the Quarterly Report on Form 10-Q for the quarters ended July 1, 2012, and September 30, 2012. Generally Accepted Accounting Principles The Company reports its financial results in accordance with GAAP. Additionally, the Company supplements reported GAAP financials with non-GAAP measures which are included in related press releases and reports furnished to the SEC, copies of which are available at the Company’s website: http://www.exar.com or the SEC’s website at: http://www.sec.gov. In this presentation, we are disclosing non-GAAP gross profit, non-GAAP operating expenses, non-GAAP operating income or loss, non-GAAP net income or loss, and non-GAAP basic and diluted net income or loss per share, which are adjusted to exclude from our GAAP results all stock-based compensation expense, amortization of acquired intangible assets, restructuring charges and exit costs, provision for dispute resolution, and related income tax effects. These non-GAAP measures are presented in part to enhance the understanding of the Company’s historical financial performance and comparability between reporting periods. The Company believes the non-GAAP presentation, when shown in conjunction with the corresponding GAAP measures, provide relevant and useful information to analysts, investors, management and other interested parties. For its internal purposes, the Company uses the foregoing non-GAAP measures to evaluate performance across reporting periods, determine certain employee benefits as well as plan for and forecast the Company’s future periods. These non-GAAP measures are not in accordance with, or an alternative for measures prepared in accordance with GAAP, and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. The Company believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP. These measures should only be used to evaluate the Company’s results of operations in conjunction with the corresponding GAAP measures.

Applications

Native Linux Kernel

CeDeFS

Native Linux FS

Storage Volume Panther I, II or AltiorPCIe Card

CeDeFS is a kernel plug-in at the file system layer that once installed will compress ALL files independent of application.

This solves a major challenge for OEM customer that currently integrate at the application. WIth CeDeFS integration is no longer necessary.

CeDeFS will run on Panther I or Panther II or the existing Altior cards. The solution is Plug-n-Play and is transparent to the operating systems once installed.
