Section 16(a) Beneficial Ownership Reporting Compliance

Section 16 of the Securities Exchange Act requires our directors and certain of our officers, and persons who own more than 10% of a registered class of our equity securities, to file initial reports of ownership and reports of changes
in ownership with the SEC. SEC regulations also require these persons to furnish us with a copy of all Section 16(a) forms they file. Based solely on our review of the copies of the forms furnished to us and written representations from our
officers who are required to file Section 16(a) forms and our directors, we believe that all Section 16(a) filing requirements were met during fiscal 2009, except that Steel Partners II filed one Form 4 late during fiscal 2009, which
covered a total of three open market purchases of shares of our common stock by Steel Partners II.

Audit Committee

We have an Audit Committee of our Board of Directors, the current members of which are John Mutch (Chair), Jon S. Castor and Lawrence J.
Ruisi, each of whom are independent as defined by the rules of The NASDAQ Stock Market. Our Board of Directors has also determined that Lawrence J. Ruisi qualifies as an audit committee financial expert, as defined under
Item 407(d)(5) of Regulation S-K and meets the NASDAQ financial sophistication requirement of having past employment experience in finance or accounting, requisite professional certification in accounting, or any other comparable experience or
background which results in the individuals financial sophistication, including being or having been a chief executive officer, chief financial officer or other senior officer with financial oversight responsibilities. Joseph S. Kennedy served
on our Audit Committee until Mr. Ruisis election to our Board of Directors at our 2008 Annual Meeting of Stockholders held in October 2008. Mr. Ruisi joined the Audit Committee upon his election to our Board of Directors, and

Report of the Audit Committee

The following is the Report of the Audit Committee with respect to our audited financial statements for our fiscal year ended March 31, 2009.

The Audit Committees purpose is, among other things, to assist our Board of Directors in its oversight of its financial accounting,
reporting and controls. Our Board of Directors has determined that each member of the Audit Committee meets the independence criteria prescribed by applicable law and the rules of the SEC for audit committee membership and each is an
independent director within the meaning of the listing standards of The NASDAQ Global Market. The Audit Committee operates under a written charter, which was formally adopted by the Board of Directors in June 2000 and most recently
updated in March 2004.

Our management is responsible for the preparation, presentation and integrity of our financial
statements, including setting the accounting and financial reporting principles and designing our system of internal control over financial reporting. Our independent registered public accounting firm, PricewaterhouseCoopers LLP, is responsible for
performing an independent audit of our Consolidated Financial Statements and for expressing opinions on the conformity of our audited financial statements to generally accepted accounting principles and on the effectiveness of our internal control
over financial reporting based on their audit. The Audit Committee oversees these processes, although members of the Audit Committee are not engaged in the practice of auditing or accounting, and their functions are not intended to duplicate or to
certify the activities of management or PricewaterhouseCoopers LLP.

The Audit Committee has reviewed and discussed our
audited Consolidated Financial Statements for the fiscal year ended March 31, 2009 with management and PricewaterhouseCoopers LLP. The Audit Committee met with PricewaterhouseCoopers LLP, with and without management present, to discuss the
results of its examinations, its evaluation of our internal control over financial reporting and the overall quality of our financial reporting.

The Audit Committee also has discussed with PricewaterhouseCoopers LLP the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA,Professional Standards
, Vo. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T. The Audit Committee has received the written disclosures and the letter from PricewaterhouseCoopers LLP required by the Public Company Accounting

Item 11.Executive Compensation

Compensation Discussion and Analysis

This section discusses our executive compensation philosophy, decisions and practices for fiscal 2009. It places in perspective the earnings of our named executive officers listed in the Summary Compensation Table below.

Compensation Philosophy and Overview

We believe that the most effective compensation program is one that is designed to reward the achievement of our financial and strategic goals, and which aligns executives interests with those of
our stockholders.

The compensation programs for our named executive officers have three principal elements which are
developed in part by referencing the 50th percentile of our comparable market: a base salary, cash incentive bonuses linked to achievement of financial and corporate goals, and equity-based incentive compensation. The base salary is designed to
serve as a fixed portion of compensation; the cash incentive bonus serves as an incentive for our executives to drive short-term corporate financial and non-financial goals without excessive risk-taking; and the equity-based incentive compensation
is designed to drive longer-term Company performance, retain executives through longer-term vesting and align the interests of our executive officers with the interests of our stockholders by providing a performance-based ownership stake in the
Company. In addition, we provide our executive officers benefits that in most cases are available generally to all of our salaried employees. As further discussed below, we largely view these primary components of our compensation as distinct in
that we seek to provide salary, bonus and equity awards that are each competitive at appropriate levels with our peer companies.

The compensation philosophy of the Compensation Committee of the Board of Directors (the Committee) is to keep cash compensation at a competitive level while providing the opportunity to be significantly rewarded through equity
if Adaptec and our stock price perform well over time. We believe that our executive officers should have a larger portion of their equity incentive awards at risk compared with our other employees. Specifically, we believe that over the long term,
executive officers should have a greater percentage of their equity compensation in the form of stock options and performance-contingent stock rather than time-based restricted stock, as the economic value of stock options and performance-contingent
stock is more aligned with the objectives of our shareholders.

Fiscal Year 2009. In addition to the factors that the
Committee normally considers in formulating our compensation program in 2009, the Committee also took account of several specific factors that impacted our business: (1) a strategic acquisition; (2) a divestiture initiative;
(3) significant outsourcing and attrition; (4) reduced OEM revenue; and (5) aggressive cost cutting initiatives.

##### Table of Contents

Because of these circumstances: (1) The Committee didnt make significant changes
to base salaries. The Committee kept base salaries generally at the prior years level due to the Committees desire to contain costs and the Committees belief that an overall increase in base pay was not required to keep the Company
reasonably competitive with the base pay of our peers. (2) The Committee split our cash bonus incentive into two six-month bonus periods (instead of an annual measurement). The Committee evaluated the financial component of our bonus incentive
based on six-month intervals due to the divestiture of the Snap Server NAS business, which was the majority of our segment previously known as SSG, in the first half of the fiscal year and the acquisition of Aristos in the second-half of the fiscal
year. The financial measurement goal for each of the six month periods in fiscal 2009 was a specified level of pro-forma operating profit (loss) before income taxes (OPBT). The OPBT differs from generally accepted accounting principles
(GAAP) operating profit (loss) in that OPBT primarily excludes stock-based compensation expense, expense associated with our management liquidation pool, restructuring charges, impairment charges of long-lived assets and goodwill, and
gain on extinguishment of debt. For the first six months this goal was based on the OPBT profit performance, exclusive of our acquisition of Aristos and disposition of SSG. For the second-half of the year, the financial goal was formulated inclusive
of the acquisition of Aristos in the later part of the second fiscal quarter. Aristos was in its initial phase of revenue generation with two key OEMs. While the Board of Directors (Board) and management believed that a consolidated OPBT
loss was unavoidable in the second-half of fiscal 2009, the Committee maintained, and the CEO supported, an aggressive financial goal because our objective is to move the Company to a practice of funding the bonus pool out of net profits. Going
forward, the Committee intends to measure financial performance at the end of the fiscal year based on the attainment of pro-forma net profits.

Equity compensation granted to executive officers included three elements: options, performance-contingent stock, which was granted shortly after the close of the fiscal year 2009, and time-based
restricted stock. The first-time addition of performance-contingent stock to the mix of equity awards (with a corresponding reduction in the size of time-based restricted stock awards) shows our intent to increasingly utilize equity awards where the
ultimate value of the award is more closely linked to Companys performance and growth in shareholder value.

Role of the
Compensation Committee

The current members of the Committee are Jon Castor, who is the Chair of the Committee, Robert
Loarie and John Quicke. Mr. Castor, Mr. Loarie and Mr. Quicke served on the Committee for all of fiscal 2009.

The Committee ensures that our executive compensation and benefits program is consistent with our compensation philosophy and our corporate governance guidelines and is empowered to determine executive officers total compensation,
and, subject to the approval of the Board, to determine our CEOs total compensation.

The Committee reviews our overall
compensation strategy at least annually to ensure that it promotes stockholder interests, supports our strategic and tactical objectives and provides for appropriate rewards and incentives for our executive officers. The Committees most recent
overall compensation review occurred in February 2009.

In fiscal 2009, all Committee members attended all Committee meetings.
Typically, Committee meetings are also attended by, for all or a portion of appropriate meetings, our CEO and our Vice President of Human Resources. An independent compensation consultant from Compensia, Inc. (Compensia) and a
compensation legal specialist from Fenwick & West LLP provided support to the Committee, including attending meetings from time to time.

Review of Executive Officers and their Compensation

The Committee and our Board are responsible for the
review of our CEOs performance. In fiscal 2009 the Chairman of the Committee led a formal review that included a self-evaluation by the CEO and input from each member of the Board. The results were shared with the CEO, members of the Committee
and all members of the Board.

Mr. Subramanian Sundaresh, our CEO, annually reviews the performance of each of our
other executive officers. As part of this process, each executive officer also completes a self assessment of his/her performance.

Mr. Sundaresh rates the performance of his direct staff and the Committee rates the performance of Mr. Sundaresh in consultation with the other non-executive directors of the Board.

Mr. Sundareshs recommendations based on his reviews of executives reporting to him, peer compensation surveys and other relevant
information, including with respect to continued employment, salary adjustments, incentive awards and equity award amounts, are presented to the Committee. The Committee thoughtfully considers the CEOs recommendations when exercising its own
judgment in making compensation decisions and awards to our executive officers who report to the CEO.

Survey Analysis

In fiscal 2009, we engaged Radford Surveys + Consulting, a business unit of AON Consulting (Radford), to
provide comprehensive compensation data. Radford conducts a number of compensation surveys for the technology industry. The surveys compare compensation practices for executives among other high technology companies and cover base salary, cash
incentives, stock equity incentive grants and total cash as a percentage of total direct compensation.

Radford provides
quarterly summaries of industry trends to our Vice President of Human Resources, which enables Human Resources to remain current on total compensation trends for the broader population and for executive officers. This information is shared with the
Committee. Our Vice President of Human Resources also reviews the Radford Total Company Results survey comprised of data for executives from approximately 125 technology companies with $50 million to $200 million in annual revenues. In addition to
this information, which is shared with the Committee, the Committee also considers other reference points in reviewing compensation data. In particular, the Committee reviews the Radford Total Custom Company Results survey provided by Radford that
compares executive compensation information for a peer group of high technology companies or their divisions, with $100 million to $500 million in annual revenues. The peer group is primarily in the storage, computer peripherals, and semiconductor
components businesses with which we compete for executive and technical employees. The list of peer companies, their industry classification and revenue ranges is as follows:

The companies included in our peer group may change from year to year when the underlying
criteria used to determine a match change. For example, a company may elect to no longer participate in the survey on an annual basis or a companys revenue may change materially relative to ours. Similarly new companies may be added into the
survey having revenue that matches our revenue levels or industry. Our peer group list compared to last fiscal year includes additional companies in the $100 million$199.9 million range and in the semiconductor components industry due to our
reduced revenue, our new semiconductor business and our strategic plan direction.

External Advisors

The Committee has the authority to engage the services of outside advisors, and does so as needed. In fiscal 2009 the Committee
selectively engaged the services of Compensia as an independent advisor to assist the Committee in its review of fiscal 2009 compensation for executive officers and in a review of Board compensation. In the projects that the Committee assigned to
Compensia, there were no restrictions placed on the scope of Compensias review of the Companys compensation arrangements with its executive officers and in its review of Board compensation, other than that Compensia was asked to keep
their fees within a specified budget. The Committee selectively engaged the services of a compensation legal specialist with Fenwick & West LLP for legal advice in connection with compensation related matters.

Accounting and Tax Implications of Our Compensation Policies

In designing our compensation programs, the Committee considers the financial accounting and tax consequences to the Company, as well as the tax consequences to employees. We account for equity
compensation paid to our employees under SFAS No. 123(R), which requires us to estimate and record an expense over the service period of the award. The SFAS No. 123(R) cost of our equity awards is considered by management as part of our
equity grant recommendations to the Committee.

Section 162(m) of the Internal Revenue Code places a limit of $1 million
on the amount of compensation that we may deduct for income tax purposes in any one year with respect to our CEO and certain other of our most highly compensated executive officers. This limitation does not apply to compensation that is considered
performance-based under applicable tax rules. Our executive stock options and our performance based restricted stock awards are intended to qualify as performance-based, so that compensation attributable to these forms of
equity incentives is fully tax deductible. However, time-based restricted stock units (RSUs), awarded by the Company in fiscal 2009 and prior years do not meet the requirements of Section 162(m) as performance-based. Therefore, the
fair market value of the shares that vest during a particular year will be counted along with other non-performance-based compensation in that year in determining whether the $1 million limit for non-performance-based compensation is exceeded.
Although we also provide cash compensation to executives in forms that do not meet the requirements for performance-based compensation, such as base salary and annual incentive pay, we have no individuals who received
non-performance-based cash compensation in excess of the Section 162(m) tax deduction limit in fiscal year 2009, excluding Mr. Gupta as set forth below. In future years, payment of cash or settlement of restricted stock or RSU amounts may
be non-deductible because they are not performance-based under Section 162(m). The Committee has determined that it is important to retain flexibility and competitiveness in its compensation program, and that while it is also important to be
mindful of the $1 million limit, compensation in excess of the $1 million limit may not always qualify as performance-based within the meaning of Section 162(m).

Fiscal Year 2009 Executive Compensation Program

Components of our Compensation
Program

Base Salary.    Base salaries serve as the fixed cash portion of executive
compensation. In fiscal 2009, we generally maintained the base salary for each of the persons who were named executive officers at the same level as the fiscal 2008 salaries. The Committees goal in fiscal 2009 was to benchmark
salaries at or near the middle (50th percentile) of the market based on the survey information discussed above under Survey

##### Table of Contents

Analysis, input from Compensia, and our own hiring experience, and the Committee determined that salary increases were not necessary to achieve this level of compensation. We believe the
officers should be paid competitively and generally not above or below the market data unless their experience, capabilities, and/or responsibilities warrant either a higher or lower placement compared to market. The base salaries of our executive
officers reflect their relative positions and responsibilities within the Company. The base salary of Mr. Sundaresh, our CEO, was increased to $450,000 on April 1, 2006 and has not been increased since then primarily due to the Company
subsequently matching to lower revenue companies in the Radford Total Company Results ($100 million$200 million Revenue) and the Radford Total Custom Company Results ($100 million$500 million Revenue) surveys.

The base salary of Mr. Lowe, Vice President of Corporate Development, was set at $260,000 on April 1, 2006 and did not change
through the end of the 2009 fiscal year. Shortly after fiscal year end, effective April 6, 2009, Mr. Lowes title was changed to Vice President of Marketing and Business Development and his base salary was reduced to $240,000. His new
base salary was determined largely by benchmarking to peers at the 50th percentile as previously described. The base salary for Ms. Dotz, Chief Financial Officer, who joined us at the end of fiscal 2008 was $265,000 and did not change in fiscal
2009. The target annual earnings for Mr. Noellert, Vice President of Worldwide Sales, who is a named executive officer for fiscal 2009 was $310,000, which includes a base salary of $217,000 and target incentives for revenue-related achievements
of $93,000. Mr. Noellerts target annual earnings include both base and incentive pay, with the performance targets that serve as the basis for awarding Nr. Noellert his incentive pay to be established by the CEO and the Committee at the
beginning of each fiscal year. Mr. Noellerts target annual earnings increased from $291,500 to $310,000, effective August 20, 2007 when he was promoted from Vice President of Sales for North America to Vice President of Worldwide
Sales. His new target annual earnings were determined largely by benchmarking to peers at the 50th percentile as previously described. Mr. Gupta is no longer with the company; his base pay is discussed below under Acquisition of
Aristos.

Executive Bonus Incentive Program.    We maintain the Adaptec Incentive Plan (the
AIP), a cash incentive program, for executive officers and other Adaptec employees. In fiscal 2009, the AIP consisted of two six-month bonus periods, and funding of the plan was conditioned upon two major components: specific financial
goals and non-financial corporate goals that are approved by the Committee. The Committee placed greater emphasis on the specific financial goals because we sought to drive Company performance primarily through specific objective financial metrics.
The non-financial corporate goals accounted for 25% of the funding of the AIP pool and the financial goals accounted for 75% of the funding of the pool. The financial goals component was based upon Adaptec achieving a minimum threshold of OPBT for
each six-month bonus period. The Committee determined the goals, and the weight of each goal in consultation with management. Achievement of goals was measured at the beginning of the third fiscal quarter for the first half cash bonuses and at the
beginning of the first fiscal quarter of the following fiscal year for the second half cash bonuses.

The target bonus as a
percent of salary for each executive officer was established when the officer was hired to his/her position. Each year, the Committee validate that the target bonus remains appropriate for the officers role based on market data. An executive
officer can earn 0% to 200% of his or her target incentive. The Committee referenced the same Radford survey data discussed above for each position held by an executive officer to assist us in determining cash bonus incentive targets as a percentage
of base salary. As with other elements of compensation, the Committee focuses principally on the 50th percentile of market. The bonus levels awarded to our executive officers are based on the Companys achievement levels with respect to the
financial and non-financial corporate goals, and on the basis of their individual performance. The differences in target bonuses among our named executive officers are based on their relative positions and responsibilities within the Company and are
based on the relative target bonus amounts reflected in the survey data. For fiscal 2009, the target bonus payment for each six-month period for Mr. Sundaresh was 85% of his base salary, and 50% of his or her base salary for Mr. Lowe and
Ms. Dotz. Mr. Noellert is not eligible to participate in the Companys AIP, as his target bonus payment is tied to sales achievement. Based upon this structure, Mr. Sundaresh could have received an actual bonus of between 0 and
170% of his base salary for the fiscal year, divided over two six-month periods. The annual target bonus was 85% of his base salary, or $382,500.

The individual and organizational goals as discussed below are typically proposed by the CEO
to the Committee, revised and reformed in response to the Committees guidance, and ultimately determined by the Committee and, for the CEO, by the Board. The individual performance factors utilized by the Committee and the CEO in the case of
the named executive officers were: 1) performance to their individual and organizational goals; 2) contributions to achievement of the corporate goals; 3) contributions to achievement of the financial goals; and 4) subjective evaluation of their
leadership. These individual and organizational goals have been intended to be difficult but achievable. Individual performance for executive officers, other than Mr. Sundaresh, is based on an evaluation by Mr. Sundaresh and the Committee,
and the Committee determines the level of Mr. Sundareshs achievement of his individual goals and discusses this with the Board. The Committee also determines and discusses with the Board, the Companys performance with respect to
financial and non-financial goals, in consultation with management and after referring to the relevant performance data, including in some cases preliminary unaudited financials, as provided to the Committee by management. The Committee reserves the
right to adjust upward or downward based on the final audited financials.

In the first six months, the Company achieved over
100% of its financial goal and 93.5% (on a weighted average basis) of its non-financial corporate goals. The 100% level of achievement for the financial goal was OPBT for our business, exclusive of our acquisition of Aristos and disposition of SSG,
of $0 to $1.5 million. The actual OPBT of our business was $1.7 million. After a recommendation by the CEO, and in light of general economic conditions, the Committee determined that the level of achievement for the financial goal should not be
greater than 100%. The non-financial corporate goals included the divestiture of the SSG business; growth in Serial Channel Point-of-Sale revenue; the development, launch, and revenue attainment of the Series 2 product and the Series 5 product with
power management features; the outsourcing of specific engineering projects; a partnership with a third party RAID provider; and inventory management. The Committee established these goals as stretch goals and believed that, taken as a whole, they
were achievable, but very difficult. As a result of this high level of achievement, the Committee approved a funding budget of 98% of the AIP target. This funding budget was determined by the following weighted average calculation: (93.5% x 25%
corporate goals) + (100% x 75% financial goals) = 98%. Based on the corporate and financial goal attainment, Mr. Sundareshs budgeted target was $188,142; the Committee approved an actual award to Mr. Sundaresh of $190,000 after
taking into account the Companys attainment of corporate and financial goals and his role in successfully leading the Company to a profitable first half of the fiscal year and for completing the acquisition of Aristos. Mr. Lowes
budgeted target was $63,944; the Committee approved an actual award of $60,000 after taking into account Mr. Lowes project management of the divestiture of SSG to Overland Storage and the acquisition of Aristos. Ms. Dotzs
budgeted target was $65,173; the Committee approved an actual award of $70,000 based on her evaluation and recommendations to reduce general and administrative costs and infrastructure costs, and the rationalization of common costs associated with
the Aristos acquisition. Mr. Noellert was not eligible for the Companys AIP. Mr. Noellert achieved 93.4% of his commission plan.

In the second six months of the fiscal year, the Company did not achieve its financial goal. The Company did achieve, on a weighted average basis, 52.5% of its non-financial corporate goals. Non-financial
corporate goals included reduction of selling, general and administrative costs, information technology costs, and facilities costs; significant market share growth in a key segment; design wins; and integrated roadmaps (Aristos and Adaptec, post
the acquisition of Aristos). The Committee established these goals, in consultation with the CEO and Vice President of Human Resources, as stretch goals and believed that, taken as a whole, they were achievable but very difficult. With respect to
the financial goals for the second six months of fiscal 2009, to reach the 100% level, the Company had to achieve a pro-forma OPBT between a loss of $1.5 million and breakeven ($0 million). Actual pro-forma OPBT was a loss of $5.75 million. In the
second half of fiscal 2009, we set a financial performance goal that acknowledged the high probability of an OPBT loss because of the anticipated impact during this period of the Aristos acquisition. Notwithstanding this expectation, the Committee
determined that it was in the Companys interest to provide an incentive to our executives to limit the amount of the expected loss. Partly because economic conditions deteriorated globally during the second half of our fiscal year, the stretch
financial goal was not achieved. Accordingly the Committee approved of a funding budget of only 13.125% of the AIP target. This funding budget was determined by the following weighted average calculation:

(52.5% x 25% corporate goals) + (0% x 75% financial goals) = 13.125%. Mr. Sundaresh recommended, and the Committee agreed, that he would forgo his budgeted portion of the bonus incentive of
$25,102 for the second six months due to the Companys performance and the present economic situation, and instead distribute that portion of the funds to other deserving employees in the Company. Based on the attainment of the corporate and
financial goals, Mr. Lowes budgeted target was $8,531; the Committee approved an actual award of $12,000 after taking into account Mr. Lowes successful individual work on the evaluation of the patent portfolio and the
Companys strategy development. Ms. Dotzs budgeted target was $8,695; the Committee approved an actual award of $15,000 after taking into account her exceptional individual goal achievement of managing the Companys cash and
reducing the Companys overhead costs. Mr. Gupta did not receive his budgeted target as noted under Acquisition of Aristos. Mr. Noellert is not eligible for the Companys AIP. Mr. Noellert achieved 72.5% of his
commission plan.

As shown in the table below, in total for fiscal 2009, combining the two six month periods, Messrs.
Sundaresh, Lowe, and Noellert and Ms. Dotz received less than their targets based on Adaptecs and their individual performance. Mr. Sundaresh received a total cash incentive of 42.2% of his base salary; Ms. Dotz received 32.1%
of her base salary, Mr. Lowe received 27.7% of his base salary, and Mr. Noellert received 35.9%, of his base salary.

Equity-Based Long Term Incentive Compensation.    In
fiscal 2009, the Committee determined that the Companys overhang rate (the percentage of shares held by the Companys employees and the number available to grant as a percent of total shares outstanding) of 20% exceeded industry norms.
The Company had over 21 million shares available to grant to its employees due in large measure to the number of awards that were cancelled as a result of prior Company downsizing (awards covering over 20 million shares were cancelled in
fiscal years 2006 through 2008). The Committee determined that the number of shares available for future issuance under the 2004 Equity Incentive Plan should be reduced and could be reduced given the projected need for employee stock and option
awards in the three-year planning horizon. As a result, the Committee and Board approved, and the stockholders also approved at the 2008 Annual Meeting of Stockholders, the amended 2004 Equity Incentive Plan to reduce the shares available to
14.5 million shares. However, the 2004 Equity Incentive Plan allows the shares available to increase above the 14.5 million shares by the number of shares of common stock that are released from or reacquired by the Company from awards
outstanding under the Companys 1999 Stock Plan and 2000 Nonstatutory Stock Option Plan. The amended 2004 Equity Incentive Plan also included modifications permitting all of the shares to be granted as either options, restricted stock, and/or
restricted stock units and providing for acceleration of vesting only in the event of a double trigger (that is a Change of Control coupled with termination (or constructive termination) of employment by the acquiring company). The
Company also committed to limit its fiscal year gross burn rate of equity awards to 4.8% or less. With the change in the Plan, the overhang was reduced to 15.5%, in-line with industry benchmarks.

The Committee prefers to use stock options and performance-contingent stock awards to ensure
that our executive officers have a continuing stake in our long-term success and to better align their interests with the interests of our stockholders. In the first half of the fiscal year, the Committee was concerned, based in part on the advice
of its advisors, that outstanding stock options with exercise prices in excess of our stock price were not providing adequate short-term retention incentive to retain executives in a declining market for the Company and the industry. Accordingly,
the Committee determined to include, as part of fiscal 2009, compensation time-based restricted stock awards with a shorter, two-year vesting schedule as a retention tool. In addition, to ensure longer-term alignment of executive and shareholder
interests, the Committee continued the past practice of granting options with a three-year vesting schedule to promote shareholder value growth, and introduced for the first time performance-contingent stock as a substitute for some of what would
have been, in the past, time-based restricted stock grants. Vesting of the performance-contingent stock is tied to the Company achieving positive OPBT of 10% of revenue and a return on net assets of 20%. The time-based restricted full-value stock
and the option grants were granted in August 2008 and the performance-contingent stock units were granted in April 2009 tying them to the Companys performance beginning in fiscal 2010. The performance-contingent stock, granted shortly after
the close of fiscal 2009, is listed below and will be part of the executive officers compensation tables for fiscal 2010. They are not listed in the executive officers compensation tables for fiscal 2009. The Committee believes that this three-prong
approach to equity awards achieved the goals of short term retention needed due to the lack of short-term value in prior option grants, and providing management an incentive to improve financial performance to the benefit of shareholders while also
minimizing potential dilution and compensation expense. In the future, the Committee plans to grant a combination of options and performance-contingent stock to the Companys executives and limit the use of time-based restricted stock to
special situations. The Committee believes that this approach will further align the interests of senior management more closely with shareholders.

The 50th percentile of the Radford surveys noted above was used as a reference point in setting the level of all executive officers equity awards. The Committee evaluated the value of awards to
determine a recommended range for each of our executive officers based on their relative positions and responsibilities within the Company. Mr. Sundareshs equity compensation was evaluated by reference to the CEO position; Ms. Dotz
to the CFO/Senior Financial Executive position; Mr. Lowe to the Senior Business Development Executive and/or the Senior Marketing Executive position; and Mr. Noellert to the Senior Worldwide Sales Executive position. The Committee granted
options covering a larger number of shares subject to three-year vesting and a larger number of shares of three year performance-contingent stock than of two-year time-based restricted stock due to its desire to emphasize longer term financial
performance with the goal of benefiting our stockholders. The lower number of shares subject to awards granted to Mr. Lowe reflects the more limited nature of his business development role compared to the financial and sales roles held by
Ms. Dotz and Mr. Noellert. The cumulative value of the awards were determined by calculating the stock option award value using a Black-Scholes methodology, and the time-based and performance-contingent restricted stock awards using their
full-value at grant date. The results were then compared to the 50th percentile of equity grants noted in the Radford surveys above.

Mr. Gupta, our former Vice President and General Manager of the Storage Technology
Products, joined Adaptec in September 2008 and was granted a new hire award consisting of an option to purchase 40,000 shares of Adaptec Stock and a restricted stock grant of 127,500 that was subject to certain performance-based vesting criteria.
Mr. Guptas employment with the Company was terminated prior to the vesting of any portion of the option award and any shares of the restricted stock grant. For more information regarding Mr. Guptas compensation, please see
Acquisition of AristosMr. Gupta below.

The Grants of Plan-Based Awards table below further describes
the option grants and restricted stock awards made to the executive officers during the fiscal year.

All equity-based awards
have been reflected in our Consolidated Financial Statements, based upon the applicable SFAS No. 123(R) accounting guidance. We do not have any program, plan or practice that requires us to grant equity-based awards to our executive officers on
specified dates and we have not made grants of such awards that were timed to precede or follow the release or withholding of material non-public information. Our practice has been to grant equity-based awards at regularly scheduled Committee and
Board meetings. The exercise prices of options are determined based on the closing price of our common stock on the date that the grants are approved.

Perquisites.    Our executive officers are eligible for the same health and welfare programs and benefits as other Adaptec employees. In addition, all vice president level
executives, including our executive officers, receive a car allowance valued at $650 per month, and are eligible for an annual executive physical. In addition, executive officers receive reimbursement for personal financial and tax advice up to
$2,500 per year, and survivor benefit management services up to a maximum of $3,000.

Acquisition of AristosMr. Gupta

Total Compensation.    The Company acquired Aristos, a provider of RAID silicon and
software products, in September 2008. Mr. Gupta served as Aristos President and Chief Executive Officer from June 2000 until the acquisition. Mr. Gupta joined the Company in the role of Vice President and General Manager of Storage
Technology Products. Post acquisition, his base pay was maintained by Adaptec at the same level he was receiving with Aristos: $267,586. The Company decided not to change his base pay in part because it was consistent with the 50th percentile of the
Radford Total Company Results ($50 million$200 million revenue) survey and the 47th percentile of the Radford Total Custom Company Results ($100 million$500 million revenue) survey for a Division Senior Executive position. Mr. Gupta
received a new hire stock award consisting of an option to purchase 40,000 shares of Adaptec stock and a restricted stock grant of 127,500 shares. The option was to vest 33% on the one-year anniversary of his hire date and quarterly thereafter, at
8.375% per quarter, and was to be fully vested at the end of three years. The restricted stock award was to vest upon achieving specific gross profit measurements and the release of certain new products to production. Specifically,
Mr. Gupta would vest as to 52,500 shares of the stock award upon achievement of 100% of the target gross profit goal and as to and additional 52,500 shares of the stock award upon achievement of 200% of the gross profit goal attained by April
2010, and as to 22,500 shares of the stock award upon release of certain new products to production. The Committee established these goals as stretch goals and believed that, taken as a whole, they were achievable but difficult. These grants were
determined in the context of the acquisition, and were also based on the Radford surveys noted above and with reference to the value of unvested equity held by other executives. All equity awards to Mr. Gupta were contingent on his continued
employment at the time of vesting.

For the second half of fiscal 2009, the target bonus payment for Mr. Gupta was 50% of
his base salary. Based on AIP achievement for the time period, Mr. Gupta was eligible for 11.25% of targeted funding multiplied by his 50% incentive, totaling 5.6% of his base salary. The Committee decided not to award this modest incentive due
to the Company not achieving the Aristos revenues that had been forecast at the time of the acquisition. Mr. Gupta did receive payments of $1,119,757 and $56,476, respectively, under the Management Liquidation Pool and Special Employee Bonus
Pool established pursuant to the merger agreement by which the Company acquired Aristos.

Effective as of April 10, 2009, Mr. Guptas employment with the Company was
terminated due to the realignment of the Companys organizational structure post merger and the Company and Mr. Gupta entered into a Separation Agreement. Pursuant to the separation agreement Mr. Gupta received a severance payment of
$231,565 and a payment representing accrued vacation time of $26,840. Mr. Gupta provided the Company with a general release of all claims. Mr. Guptas new hire option award to purchase 40,000 shares of Adaptec stock and his restricted
stock grant of 127,500 shares did not vest and were cancelled.

Employment Contracts

We have entered into employment agreements with each of our executive officers based on an assessment of competitive market terms and a
determination of what is needed to attract and retain the executive officers. These employment agreements provide that if such officer is terminated other than for cause (which includes violation of material duties, refusal to perform
his/her duties in good faith, breach of his/her employment agreement or employee proprietary information agreement, poor performance of duties, arrest for a felony or certain other crimes, substance abuse, violation of law or Adaptec policy,
prolonged absence from duties or death), he or she is entitled to receive (1) his or her unpaid base salary and unused vacation benefits he or she has accrued prior to the date of his of her termination; (2) a one-time payment equal to 12
months of base salary for Mr. Sundaresh, and nine months of base salary for Ms. Dotz, and Messrs. Lowe, Noellert and Gupta, plus an additional week of base salary for each year of service beyond three years of service with the Company (and
Aristos for Mr. Gupta); (3) outplacement services in an amount not to exceed $10,000 for Mr. Sundaresh and Mr. Lowe or $5,000 for Ms. Dotz and Messrs. Noellert and Gupta; and (4) reimbursement for coverage for the
executive officer and his or her dependents under Adaptecs health, vision and dental insurance plans pursuant to COBRA for a 12-month period for Mr. Sundaresh, and a nine-month period for Ms. Dotz and Messrs. Lowe, Noellert, and
Gupta following the termination of employment. The Committee (including its predecessors) selected these amounts at the time these executives were hired by the Company (or promoted to an executive position) based on its reasoned judgment, including
considering prior practice within Adaptec, information gathered from outplacement companies and, for agreements entered into after the Committee retained Compensia in January 2007, severance data provided by Compensia.

Employment agreements for Ms. Dotz and Messrs. Noellert and Gupta have a three-year term. Employment agreements for Messrs. Sundaresh
and Lowe do not have a term limit because they were given prior to term limit implementation by the Committee. Each of the employment agreements of Messrs. Sundaresh, Lowe, Noellert and Gupta and Ms. Dotz also allow for the granting of stock
options and stock awards under the 2004 Equity Incentive Plan as deemed appropriate by Adaptecs CEO and/or the Board of Directors. In addition, the employment agreement for Ms. Dotz provides for: (i) the payment of a $25,000
retention bonus on each of October 1, 2008 and April 1, 2009 if she is an active employee of the Company on those dates, (ii) an option to purchase 125,000 shares of the Companys common stock at a price equal to the fair market
value of the Companys common stock on the date of grant, vesting with respect to 25% of the underlying shares on the first anniversary of Ms. Dotzs hire date and with respect to the balance of the shares in equal quarterly
installments over the following 36 months of service and (iii) a restricted stock award of 50,000 shares, 50% of which will vest on the first anniversary of her hire date and the remaining 50% of which will vest on the second anniversary of her
hire date.

Change of Control

The change of control arrangements of our executive officers, also set forth in their employment agreements, are as follows:

If within one year of a change of control (1) there is a material reduction of the annual base and target incentive compensation specified in his or her employment agreement to which he or she does
not consent, (2) there is a failure of Adaptecs successor after a change of control to assume his or her employment agreement, (3) his or her employment is terminated without cause by Adaptecs successor, (4) there is a

substantial change in his or her position or responsibility or (5) his or her position relocates to more than 25 additional commute miles (one way) and he or she elects to be
terminated, then he or she will receive, upon signing a separation agreement and general release: (a) a one-time payment equal to his or her then-current annual base pay for Messrs. Lowe, Noellert and Gupta (one and one-half times annual base
pay in the case of Mr. Sundaresh and nine months of base pay for Ms. Dotz), (b) his or her then-current targeted bonus payout, (c) COBRA benefits for one year for Messrs. Sundaresh, Lowe, Noellert and Gupta (nine months in the
case of Ms. Dotz), (d) outplacement services not to exceed $10,000 for Messrs. Sundaresh and Lowe ($5,000 in the case of Ms. Dotz and Messrs. Noellert and Gupta), and (e) accelerated vesting of his or her stock options and
restricted stock awards as provided for under the 2004 Equity Incentive Plan. The Agreements do not provide for any tax gross-ups.

Under our 1990 Stock Plan, 1999 Stock Plan and our 2004 Equity Incentive Plan, in the event of a change in control, any awards outstanding upon the date of such change in control will have single trigger vesting accelerated as
of the date of such change in control as to an additional 25% of the unvested shares subject to such awards. We no longer make awards under our 1990 and 1999 Stock Plans. As discussed more fully below, the Committee determined during fiscal 2009,
effective for awards made after May 30, 2008, to no longer make awards that provide for single trigger acceleration. However, the Committee left unchanged a provision of the plan providing that, if within 12 months following a
change in control, an employee is terminated by the successor employer for any reason (a double trigger), such employees awards outstanding upon such change in control that are not yet exercisable and vested on such date shall
become 100% vested and exercisable.

The Committee eliminated the single trigger acceleration of vesting upon
a change in control described above, effective for all awards after May 30, 2008. With this change and the three-year term limit, we believe our future executive severance and change of control practices are now more generally in line with
those in place at other technology companies. We believe these change of control arrangements, the value of which are contingent on the value obtained in a change of control transaction, effectively create incentives for our executive team to build
stockholder value and to obtain the highest value possible should we be acquired in the future, despite the risk of losing employment and potentially not having the opportunity to otherwise vest in equity awards which comprise a significant
component of each executives compensation. These arrangements are intended to attract and retain qualified executives who could have other job alternatives that may appear to them to be less risky absent these arrangements. Except for the
acceleration of a portion of the grants previously given to our executive officers as described above, our change of control arrangements for our executive officers are double trigger, meaning that acceleration of vesting does not occur
upon a change of control unless the executives employment is terminated involuntarily (other than for cause) within 12 months following the transaction. We believe this structure strikes the appropriate balance between executive recruitment
and retention, the needs of potential acquiring companies, who often place significant value on retaining an executive team, and our desire to contain the cost of any change in control to our shareholders.

Nonqualified Deferred Compensation

The Adaptec Deferred Compensation Plan was terminated in fiscal 2008 resulting in the distributions of funds held under the plan during fiscal 2008 to the named executive officers who participated in the
plan.

(4) the officers position relocates to more than 25 additional commute miles (one way).

|(2) | Under our 1990 Stock Plan, 1999 Stock Plan and 2004 Equity Incentive Plan, in the event of a Change in Control, any awards outstanding upon the date of such Change in
Control will have their single trigger vesting accelerated as of the date of such Change in Control as to an additional 25% of the shares subject to such awards. As discussed in Compensation Discussion and Analysis, equity
awards granted subsequent to May 30, 2008 will not contain this single trigger acceleration. However, if within 12 months following a Change in Control, an employee is terminated by the successor employer for any reason (a
double trigger), such employees outstanding awards that are not yet exercisable and vested on the date of such Change in Control shall become 100% vested and exercisable. The value of the equity acceleration was calculated
based on the assumption that the change in control occurred and the officers employment terminated on March 31, 2009, and that the fair market value per share of our common stock on that date was $2.40, which was the closing trading price
of our common stock on The NASDAQ Global Market on March 31, 2009. The value of option vesting acceleration was calculated by multiplying the number of unvested shares subject to acceleration by the difference between $2.40 and the exercise
price per share of the accelerated option. The value of stock vesting acceleration was calculated by multiplying the number of unvested shares by $2.40.

Director Compensation

Overview

Our one director who is a company employee,
Mr. Sundaresh, our CEO, receives no additional or special compensation for serving as a director. Our non-employee directors receive a combination of cash and equity compensation for serving on our Board. In addition, we reimburse non-employee
directors for out-of-pocket expenses incurred in connection with attending Board and committee meetings.

Effective
September 4, 2009, the Board of Directors confirmed the appointment of Joseph S. Kennedy as Chairman of the Board and approved his full duties and compensation. Mr. Kennedy will collaborate with and assist management, on behalf of the
Board, in connection with development of the Companys financial and operating plan and the Companys strategic and product plans. Mr. Kennedy will also review and evaluate, on behalf of the Board, the functioning and capabilities of
the Companys management team and the Companys operations, and perform the duties normally incident to the role of Chairman. Mr. Kennedy will receive $8,000 per month as Chairman of the Board, which amount will be reviewed by the
Board on a quarterly basis and is in addition to compensation Mr. Kennedy receives as a member of the Board and the Governance and Nominating Committee of the Board.

Cash Compensation

In fiscal year 2009, our non-employee directors
received (1) an annual cash retainer of $26,000 paid at the rate of $6,500 per fiscal quarter, (2) a per-meeting fee of $3,000 for each Board meeting attended (either in person or by telephone); however, the Chairperson of the Board may
designate a given meeting as a $2,000-reduced-fee meeting and (3) a per-meeting retainer of $1,200 for each Board committee meeting attended that the Chairperson of the committee designates a formal meeting. In addition, (1) the Chairman
of the Board was

##### Table of Contents

entitled to receive an annual retainer of $10,000 and (2) the chairmen of the Audit, Compensation and Governance and Nominating Committees were entitled to receive an annual retainer of
$10,000, $7,000 and $4,500, respectively, and other members of such committees receive one-half of the retainer that the Chairman of such committee receives. The Board retainer and all Board and committee meeting fees are paid quarterly. Board
Chairman and committee cash retainers are paid annually, at the end of the fiscal year, and are prorated in the event of partial-year service.

Effective April 2009 (the start of fiscal year 2010) the per-meeting board fee was reduced by the Board to $2,000 for each Board meeting attended (either in person or by telephone); however, the
Chairperson of the Board may designate a given meeting as a $1,000 reduced-fee meeting. Also effective April 2009, a Committee Chairperson may designate a committee meeting as a reduced fee meeting, and in that case, the Committee meeting fee will
be $600 instead of $1,200.

In May 2009, the Board of Directors formed a committee consisting of Messrs. Castor, Kennedy and
Ruisi to review and explore the strategic alternatives of the Company, the Strategic Committee. Subsequently, Mr. Howard was added to the Strategic Committee. Compensation for participation in the Strategic Committee has yet to be determined.

Equity Compensation

Our 2006 Director Plan is a discretionary plan and does not provide for automatic granting of options and other equity awards to our non-employee directors. Instead, our Board of Directors
approves equity awards under that plan. Our compensation program practice for non-employee directors provided for an initial award of options to purchase 32,500 shares of our common stock and 16,250 shares of restricted stock upon becoming a member
of our Board of Directors; the option grant and restricted stock vests 33% on the one-year anniversary of service with our Company and quarterly thereafter and are fully vested at the end of three years. Continuing directors received annual awards
of options to purchase 12,500 shares of our common stock that vest quarterly over one year and 6,250 shares of restricted stock that fully vest on the earlier of 12 months from the date of grant or the next annual shareholders meeting.

In May 2009, the Board agreed to change the annual equity award for continuing directors to grants of options to purchase 12,500 shares
of our common stock that vest quarterly over one year (and will vest in full at the next annual shareholder meeting if not already fully vested) and 12,500 shares of restricted stock which fully vest on the earlier of the next annual shareholders
meeting or 12 months after the date of grant. This change will be effective at the shareholders meeting in 2009. The initial grant for new directors remains unchanged, and is described above.

Equity awards and vesting schedules are subject to change by the Committee with approval by the Board.

Item 12.Security Ownership of Certain Beneficial Owners and
Management and Related Stockholder Matters

STOCK OWNERSHIP OF PRINCIPAL STOCKHOLDERS AND MANAGEMENT

The following table presents certain information regarding the beneficial ownership of our common stock as of May 19, 2009 by
(a) each beneficial owner of 5% or more of our outstanding common stock known to us, (b) each of our directors and our director nominee, (c) each of our named executive officers listed in the Summary Compensation Table
above and (d) all of our current directors and executive officers as a group.

The percentage of beneficial ownership for
the table is based on approximately 120,700,658 shares of our common stock outstanding as of May 19, 2009. To our knowledge, except under community property laws or as otherwise noted, the persons and entities named in the table have sole
voting and sole investment power over their shares of our common stock. Unless otherwise indicated, each beneficial owner listed below maintains a mailing address of c/o Adaptec, Inc., 691 South Milpitas Boulevard, Milpitas, California 95035.

The number of shares beneficially owned by each stockholder is determined under SEC rules and is not necessarily indicative
of beneficial ownership for any other purpose. Under these rules, beneficial ownership includes those shares of common stock over which the stockholder has sole or shared voting or investment power and those shares of common stock that the

Item 13.Certain Relationships and Related Transactions, and
Director Independence

Transactions with Related Persons

Related Party Transactions Policy and Procedures

Any related party transactions, excluding compensation (whether cash, equity or otherwise), which is delegated to the Compensation Committee, involving one of our directors or executive officers, must be
reviewed and approved by the Audit Committee or another independent body of the Board of Directors. Any member of the Audit Committee who is a related party with respect to a transaction under review may not participate in the deliberations or
vote on the approval or ratification of the transaction. However, such a director may be counted in determining the presence of a quorum at a meeting of the committee that considers the transaction. Related parties include any of our directors or
executive officers, certain of our stockholders and their immediate family members. To identify any related party transactions, each year, we require our directors and executive officers to complete questionnaires identifying any transactions with
us in which the executive officer or director or their family members has an interest. In addition, the Nominating and Governance Committee of our Board of Directors determines, on an annual basis, which members of our Board of Directors meet the
definition of independent director, as defined in the rules of The NASDAQ Stock Market, and reviews and discusses any relationships with a director that would potentially interfere with his or her exercise of independent judgment in
carrying out the responsibilities of a director.

Certain Related Party Transactions

Settlement Agreement with Steel Partners

On October 26, 2007, we entered into a Settlement Agreement (the Settlement Agreement) with Steel Partners and Steel Partners II (collectively, Steel) to end the election
contest that was to occur at our 2007 Annual Meeting of Stockholders. Steel Partners, our largest stockholder, beneficially owns approximately 19% of our common stock as of May 19, 2009.

Pursuant to the Settlement Agreement, we agreed:



| |  |  | To increase the size of our Board of Directors from eight to nine members prior to the 2007 Annual Meeting of Stockholders;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | That Judith M. OBrien and Charles J. Robel would not stand for re-election at the 2007 Annual Meeting of Stockholders;
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | To nominate, recommend, support and solicit proxies for each of Jack L. Howard, John J. Quicke and John Mutch (collectively, the Steel
Nominees) for election to our Board of Directors at the 2007 Annual Meeting of Stockholders;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Following the election of the Steel Nominees to our Board of Directors at the 2007 Annual Meeting, of Stockholders to appoint John Mutch to our Audit
Committee, John J. Quicke to our Compensation Committee and Jack L. Howard to our Nominating and Governance Committee;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the event of a vacancy of a Steel Nominee prior to our 2008 Annual Meeting of Stockholders, to allow Steel Partners to designate another person to
our Board of Directors to fill the vacancy;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To appoint a Steel Nominee to any committee of our board of directors, if established in the future;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | That during the period from the date of the 2007 Annual Meeting of Stockholders to the date of our 2008 Annual Meeting of Stockholders, the size of our
Board of Directors will not exceed nine members;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | That during the period from October 26, 2007 to immediately following the 2007 Annual Meeting of Stockholders, we would not enter into any binding
agreement or arrangement related to any acquisition or purchase of assets or a business that constitutes 20% or more of our net revenues, net income or assets, or 20% or more of any class or series of our securities, unless either (1) the
binding agreement or arrangement requires us to obtain the approval of our stockholders to complete the transaction or (2) Steel Partners provides its prior written approval of such transaction;

| |  |  | That following the 2007 Annual Meeting of Stockholders, we and the Steel Nominees would review our business, financial condition, results of operations
and outlook and will use commercially reasonable efforts to develop a set of mutually agreeable goals for improving our performance. After we agreed upon these goals, we and the Steel Nominees would use commercially reasonable efforts to engage as
soon as reasonably practicable, but no later than 60 days after developing the mutually agreed upon goals, a third-party consultant to assist us in making recommendations to achieve these goals; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To reimburse Steel up to $50,000 for expenses that it incurred in connection with its activities relating to the 2007 Annual Meeting of Stockholders,
including the Settlement Agreement.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Pursuant to the Settlement Agreement, Steel agreed:



| |  |  | To be present at the 2007 Annual Meeting of Stockholders and to vote all of the shares of our common stock that it beneficially owns at the 2007 Annual
Meeting of Stockholders in favor of the election of each of our incumbent directors; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | To refrain from taking certain actions during the period beginning on October 26, 2007 and ending immediately following the 2007 Annual Meeting of
Stockholders, including: taking certain actions with respect to tender or exchange offers, business combination transactions and election contests; selling the shares of our common stock that it beneficially owns; and seeking to amend our
certificate of incorporation or bylaws.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In December 2007, we held our 2007 Annual Meeting of Stockholders,
at which our stockholders elected nine directors to our Board of Directors, including each of the Steel Nominees. Mr. Howard is the President of Steel Partners and Mr. Quicke is a Managing Director and operating partner of Steel Partners.
Steel represented to us in the Settlement Agreement that Mr. Howard and Mr. Quicke may be deemed to be affiliates of Steel Partners II under the rules of the Exchange Act, but that Mr. Mutch was not an affiliate of Steel Partners II.
Following our 2007 Annual Meeting of Stockholders, Mr. Quicke was appointed to our Compensation Committee, Mr. Howard was appointed to our Nominating and Governance Committee and Mr. Mutch was appointed to our Audit Committee. We have
compensated each of the Steel Nominees with equity awards or equity-based awards as described under the caption Director Compensation.

The Settlement Agreement terminated immediately following the 2007 Annual Meeting of Stockholders, except as to specific provisions as set forth in the Settlement Agreement.

Indemnification Arrangements

We have entered into separate indemnification agreements with our directors and officers that could require us to, among other things, indemnify them against certain liabilities that may arise by reason
of their status or service as directors or officers.

Other than as set forth in this section and the compensation
arrangements set forth under the caption Executive Compensation, since April 1, 2008 there has not been, nor is there currently proposed, any transaction in which we were or will be a participant and in which the amount involved
exceeded $120,000 and in which any executive officer, director, 5% beneficial owner of our common stock or member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest.

Independent Directors

Our
Chief Executive Officer, Subramanian Sundi Sundaresh, is a member of our Board of Directors. Each of our current non-employee directors, Jon S. Castor, Jack L. Howard, Joseph S. Kennedy, Robert J. Loarie, John Mutch, John J. Quicke,
Lawrence J. Ruisi and Douglas E. Van Houweling qualifies as independent in accordance with the rules of The NASDAQ Stock Market. Our former director, D. Scott Mercer, who did not seek re-election at our 2008 Annual Meeting of
Stockholders, also, during his directorship, qualified as

independent in accordance with the rules of The NASDAQ Stock Market. The NASDAQ independence definition includes a series of objective tests, including that a director may not be our
employee and that the director has not engaged in various types of business dealings with us. In addition, as further required by the NASDAQ rules, our Board of Directors has made a subjective determination as to each independent director that no
relationship exists which, in the opinion of the Board of Directors, would interfere with the exercise of such directors independent judgment in carrying out the responsibilities of a director.

Audit Committee Pre-Approval Policies and Procedures

Section 10A(i)(1) of the Exchange Act and related SEC rules require that all auditing and permissible non-audit services to be performed
by a companys principal accountants be approved in advance by the Audit Committee of the Board, subject to a de minimis exception set forth in the SEC rules (the De Minimis Exception). Pursuant to Section 10A(i)(3) of the
Exchange Act and related SEC rules, the Audit Committee has established procedures by which the Chairperson of the Audit Committee may pre-approve such services provided the pre-approval is detailed as to the particular service or category of
services to be rendered and the Chairperson reports the details of the services to the full Audit Committee at its next regularly scheduled meeting. None of the audit-related or non-audit services described above were performed pursuant to the De
Minimis Exception during the periods in which the pre-approval requirement has been in effect. In the 2009 and 2008 fiscal years, the Audit Committee followed SEC guidelines in approving all services rendered by PricewaterhouseCoopers.
