PROXY STATEMENT

GENERAL INFORMATION

The enclosed proxy is being solicited by the Board of Directors of Digi International Inc., a Delaware corporation (“Digi,” “we,” “us” or “our”), for use in connection with the Annual Meeting of Stockholders to be held on Thursday, January 20, 2011, at the Minneapolis Marriott Southwest, 5801 Opus Parkway, Minnetonka, Minnesota, commencing at 3:30 p.m., Central Standard Time, and at any adjournments thereof. Only stockholders of record at the close of business on November 23, 2010 will be entitled to vote at such meeting or adjournments.

The address of our principal executive office is 11001 Bren Road East, Minnetonka, Minnesota 55343 and our telephone number is (952) 912-3444. The mailing of this Proxy Statement and form of proxy to stockholders will commence on or about December 10, 2010.

Stockholder Proposals . Stockholder proposals (other than director nominations) that are submitted for inclusion in our proxy statement for our 2012 Annual Meeting of Stockholders must follow the procedures set forth in Rule 14a-8 promulgated under the Securities Exchange Act of 1934 and our By-Laws. To be timely under Rule 14a-8, such proposals must be received by us at our principal executive office no later than August 5, 2011.

If a stockholder does not submit a proposal for inclusion in our proxy statement but desires to propose an item of business to be considered at an annual meeting of stockholders or to nominate persons for election as director at an annual meeting, then the stockholder must give timely written notice of such proposal or nominations to our Secretary at our principal executive office. To be timely under our By-Laws, we must receive notice of the stockholder’s intention to propose an item of business or to nominate persons for election as director not less than 120 days before the first anniversary of the date of the preceding year’s annual meeting (unless the date of the annual meeting is more than 30 days before or 60 days after such anniversary date, in which case such notice will be timely only is delivered not less than 120 days before the annual meeting or, if later, within 10 days after the first public announcement of the date of such annual meeting), and the notice must otherwise comply with certain other requirements contained in our By-Laws as well as all applicable statutes and regulations.

Assuming that our next annual meeting of stockholders is held not more than 30 days before nor more than 60 days after the one-year anniversary of this year’s Annual Meeting, we must receive notice of a stockholder’s intention to propose an item of business or nominate persons for election as a director on or before September 22, 2011. A stockholder’s notice will not be deemed to be submitted until we have received all of the required information.

Expenses of Soliciting . We will pay the cost of soliciting proxies in the accompanying form. In addition to solicitation by the use of the mails, certain of our directors, officers and employees may solicit proxies by telephone, email or personal contact, and have requested brokerage firms and custodians, nominees and other record holders to forward soliciting materials to the beneficial owners of our stock and will reimburse them for their reasonable out-of-pocket expenses in so forwarding such materials. To assist the Company in soliciting proxies for the 2011 Annual Meeting of Stockholders, the Company has retained D.F. King for a total fee not to exceed $6,000 plus out-of-pocket expenses.

Vote Required . A plurality of the votes of our outstanding shares of Common Stock present in person or represented by proxy at the meeting and entitled to vote on the election of directors is required for the election of directors. The affirmative vote of the holders of a majority of the outstanding shares of Common Stock present in person or represented by proxy at the meeting and entitled to vote is required for approval of the proposal to ratify the appointment of auditors. Abstentions and broker non-votes will be counted as present for purposes of determining the existence of a quorum at the meeting. However, shares of a stockholder who abstains, withholds authority to vote for the election of directors or does not otherwise vote in person or by proxy (including broker non-votes) will not be counted for the election of directors or approval of the proposal.

Our Common Stock, par value $.01 per share, is our only authorized and issued voting security. At the close of business on November 23, 2010, there were 25,107,340 shares of Common Stock outstanding, each of which is entitled to one vote. Holders of Common Stock are not entitled to cumulate their votes for the election of directors.

products. This background is particularly valuable as our board considers expansion strategies for our company. In addition, Mr. Millard’s legal background and financing experience add valuable perspective to ongoing governance and financial matters.

William N. Priesmeyer, age 65

Mr. Priesmeyer has been a member of our Board of Directors since November 2005. He has been the Chief Executive Officer of Cymbet Corporation, a manufacturer of thin film energy cells for the semiconductor industry, since November 2001. Mr. Priesmeyer served as Senior Vice President and Chief Financial Officer of Jostens Inc., a producer of educational products, from August 1997 to June 2001.

Mr. Priesmeyer provides a continuous improvement perspective towards company financial performance and operations for the board. He is also one of our audit committee financial experts.

Director Independence

None of the directors is related to any other director or to any executive officer of our company. The Board of Directors has determined that Messrs. Jackson, Millard, Nawaz, Priesmeyer and Williams, who constitute a majority of the Board of Directors, are “independent” as defined in the applicable listing standards of the Nasdaq Stock Market (“Nasdaq”). In making the independence determinations, our Board of Directors considered the following relationship: Mr. Nawaz, who has served as a director of our company since October 2006, is Executive Vice President of Worldwide Sales, Marketing and Corporate Development of Spansion Inc. During fiscal 2010, Digi purchased exclusively through independent third party distributors in the ordinary course of business an aggregate of approximately $243,000 of Spansion Inc. components. Because the purchases were made through independent third party distributors, the Board of Directors has determined that the purchases of Spansion Inc. components do not interfere with Mr. Nawaz’s exercise of independent judgment in carrying out his responsibilities as a director.

Board Leadership Structure

Our company does not have a written policy with respect to separation of the roles of Chief Executive Officer and Chairman of the Board because our Board of Directors believes it is in the best interests of our stockholders to make that determination based on the applicable circumstances. The Board of Directors is currently led by Mr. Dunsmore in his role as Chairman of the Board. The Board has determined that having our Chief Executive Officer serve as Chairman of the Board is in the best interest of our stockholders at this time, in large part because the Chief Executive Officer is responsible for the daily management of our company and the development and implementation of our corporate strategy and has regular contact and access to the people, information and resources necessary to facilitate the appropriate flow of information and to support the functions of the Board of Directors. Our independent non-employee directors have elected Mr. Nawaz from among themselves to serve as lead director to complement the Chairman of the Board’s role.

As our lead director, Mr. Nawaz (i) presides as chair of meetings of the Board of Directors when the Chairman of the Board is absent; (ii) organizes, convenes and presides over executive sessions of the independent non-employee directors, (iii) serves as the principal liaison between the independent non-employee directors and the Chairman of the Board and Chief Executive Officer, (iv) consults with the Chairman of the Board in establishing schedules and agendas for meetings of the Board of Directors, and (v) serves in such other capacities with such other duties as the independent non-employee directors may determine from time to time.

The Board of Directors has determined that this leadership structure is appropriate given the specific characteristics and circumstances of the company because it strengthens the Board’s role in fulfilling its risk oversight and general oversight responsibilities and its fiduciary duties to our stockholders. Furthermore, our company’s current leadership structure recognizes the depth of company and industry experience of Mr. Dunsmore, and the need for a leader among independent non-employee directors in order to facilitate both compliance with

listing requirements and communication among our independent directors and the Chairman of the Board and Chief Executive Officer.

The Board’s Role in Risk Oversight

The Board of Directors is actively involved in the oversight of risks facing our company and endeavors to provide management with guidance on the mitigation of identified risks. While the Board of Directors is generally responsible for risk management, certain committees of the Board of Directors are responsible for specific areas of risk relating to their respective focuses:

| • | Our Audit Committee is responsible for the oversight of financial risk relating
to our consolidated financial statements, financial reporting processes and internal
control over financial reporting. |
| --- | --- |
| • | Our Compensation Committee is responsible for the oversight of company-wide
compensation risk and reviews on an annual basis whether the risks arising from our
compensation policies and practices with respect to our employees generally are
reasonably likely to have a material adverse effect on the company. |
| • | Our Nominating and Governance Committee monitors the risks related to our
governance structure, policies and procedures. |

The chair of each committee is responsible for reporting to the full Board of Directors the activities of the committee, the significant issues that have been presented to or otherwise discussed by the committee, and the committee’s final determination with respect to such issues, as appropriate. By leveraging the particular competencies of its committees, the Board of Directors actively utilizes its leadership structure to administer its role in the risk oversight of our company.

Risks Arising from Compensation Policies and Practices

Our management recently conducted an evaluation of the risks arising from our company-wide compensation policies and practices with respect to employees. Management prepared a report and analysis of our compensation policies and practices and concluded that they do not create risks that are reasonably likely to have a material adverse effect on our company. In connection with its risk oversight role, our Compensation Committee reviewed management’s analysis and conclusions.

Committees of the Board of Directors and Meeting Attendance

The Board of Directors met 16 times during fiscal 2010. All directors attended at least 95% or more of the meetings of the Board and of the Committees on which they served during fiscal 2010. We have an Audit Committee, a Compensation Committee and a Nominating and Governance Committee. Following is a description of the functions performed by each of these Committees.

Audit Committee

Our Audit Committee presently consists of Messrs. Jackson (Chairman), Priesmeyer and Williams. The Board of Directors has determined that all members of the Audit Committee are “independent” as that term is defined in the applicable Nasdaq listing standards and regulations of the SEC and all members are financially literate as required by the applicable Nasdaq listing standards. In addition, the Board of Directors has determined that Messrs. Jackson, Williams and Priesmeyer have the financial experience required by the applicable Nasdaq listing standards and Messrs. Jackson and Priesmeyer are each an “audit committee financial expert” as defined by applicable regulations of the SEC. The Audit Committee oversees our accounting, internal controls and financial reporting process by, among other things, taking action to oversee the independence of and annual audit by the independent registered public accounting firm and selecting and appointing the independent registered public accounting firm. The Audit Committee met 16 times during fiscal 2010. As discussed below under the “Related Person Transaction Approval Policy”, the Audit Committee is also responsible for the review and approval or ratifications of transactions under our Related Person Transaction Approval Policy. The responsibilities of the Audit Committee are set forth in the Audit Committee Charter, a copy of which is available on the Investor Relations section of our website, www.digi.com. The Audit Committee reviews the Audit Committee Charter annually and

may make additional recommendations to the Board of Directors for further revision of the Audit Committee Charter to reflect changing circumstances and requirements.

Compensation Committee

We have a Compensation Committee presently consisting of Messrs. Millard (Chairman), Jackson and Nawaz. The Board of Directors has determined that all members of the Compensation Committee are “independent” as that term is defined in the applicable Nasdaq listing standards. The Compensation Committee determines the compensation of the Chief Executive Officer and all other executive officers. With respect to employees other than executive officers, the Compensation Committee oversees general compensation policies and reviews the annual incentive compensation structure. The Compensation Committee also oversees our benefit plans and administers the Digi International Inc. Stock Option Plan, the Digi International Inc. Non-Officer Stock Option Plan, the Digi International Inc. Employee Stock Purchase Plan and the Digi International Inc. 2000 Omnibus Stock Plan. The Compensation Committee met 11 times during fiscal 2010. The responsibilities of the Compensation Committee are set forth in the Compensation Committee Charter, a copy of which is available on the Investor Relations Section of our website, www.digi.com. The Compensation Committee reviews the Compensation Committee Charter annually and may recommend to the Board of Directors revisions to the Compensation Committee Charter to reflect changing circumstances and requirements. The processes and procedures used by the Compensation Committee for considering and determining executive and director compensation are described below under “Executive Compensation — Compensation Discussion and Analysis” on pages 11 through 19.

Nominating and Governance Committee

We have a Nominating and Governance Committee, presently consisting of Messrs. Priesmeyer (Chairman), Millard and Williams. The Board of Directors has determined that all members of the Nominating and Governance Committee are “independent” as that term is defined in the applicable Nasdaq listing standards. The Nominating and Governance Committee selects candidates as nominees for election as directors, advises the Board of Directors about the appropriate composition of the Board of Directors and its committees and oversees corporate governance matters. The Nominating and Governance Committee met 2 times during fiscal 2010. The responsibilities of the Nominating and Governance Committee are set forth in the Nominating and Governance Committee Charter, a copy of which is available on the Investor Relations Section of our website, www.digi.com. The Nominating and Governance Committee reviews the Nominating and Governance Committee Charter annually and may recommend to the Board of Directors revisions to the Nominating and Governance Committee Charter to reflect changing circumstances and requirements.

Director Nominee Selection Process and Criteria

The Nominating and Governance Committee generally identifies director candidates based upon suggestions from current directors and senior management, recommendations by stockholders and/or use of a director search firm. Stockholders who wish to suggest qualified candidates should write to: Digi International Inc., 11001 Bren Road East, Minnetonka, MN 55343, Attention: Chairman, Nominating and Governance Committee. All recommendations should state in detail the qualification of such persons for consideration by the Committee and should be accompanied by an indication of the person’s willingness to serve. The Nominating and Governance Committee will consider candidates recommended by stockholders in the same manner that it considers all director candidates.

Candidates for director nominees are reviewed in the context of the current composition of the Board, our operating requirements and the long-term interests of our stockholders. We do not have a formal policy regarding the consideration of diversity in identifying director nominees. The Nominating and Governance Committee will consider, at a minimum, the following factors in nominating existing and potential new members of the Board of Directors, in addition to other factors it deems appropriate based on the current needs and desires of the Board of Directors:

| • | demonstrated character and integrity, an inquiring mind, experience at a
strategy/policy setting level, sufficient time to devote to our affairs, and high-level
managerial experience; |
| --- | --- |
| • | whether the member/potential member is subject to a potentially disqualifying
factor, such as, relationships with competitors, customers, suppliers, contractors,
counselors or consultants, or recent previous employment with us; |
| • | the member’s/potential member’s independence; |

Folio 9 /Folio

Table of Contents

| • | whether the member/potential member assists in achieving a mix of members on the
Board of Directors that represents a diversity of background and experience, including
with respect to age, gender, international background, race and specialized experience; |
| --- | --- |
| • | whether the member/potential member has general and strategic business management
experience and financial experience with companies of a similar size that operate in the
same general industry as us; |
| • | whether the member/potential member, by virtue of particular experience, technical
expertise, or specialized skills, will add specific value as a member of the Board of
Directors; and |
| • | any factors related to the ability and willingness of a new member to serve, or an
existing member to continue his/her service. |

Stockholder Communications with the Board of Directors

Stockholders may communicate with the Board of Directors by addressing correspondence to Digi International Inc., 11001 Bren Road East, Minnetonka, MN 55343, Attention: Lead Director. Mr. Nawaz currently serves as the Lead Director. All such communications will be forwarded directly to the Chairman. The Chairman will forward communications directed at particular members of the Board of Directors directly to the particular members. Communications directed to the Board of Directors in general will be handled by the Lead Director.

We do not have a policy regarding attendance of members of the Board of Directors at annual meetings of our stockholders. One director attended the January 2010 Annual Meeting of Stockholders.

Compensation Committee Interlocks and Insider Participation

The Compensation Committee is comprised entirely of independent, outside directors. No member of this committee was at any time during fiscal 2010 or at any other time an officer or employee of the Company or any of our subsidiaries or affiliates, or has had any relationship with our company requiring disclosure in our proxy statement other than service as a director. None of our executive officers has served on the board of directors or on the compensation committee of any other entity, any officers of which served either on our board of directors or on our compensation committee.

Report of the Audit Committee

The role of our Audit Committee, which is composed of three independent non-employee directors, is one of oversight of our management and our independent registered public accounting firm in regard to our financial reporting and our internal controls respecting accounting and financial reporting. The Audit Committee also considers and pre-approves any non-audit services provided by our independent registered public accounting firm to ensure that no prohibited non-audit services are provided by the independent registered public accounting firm and that the independent registered public accounting firm’s independence is not compromised. In performing its oversight function, the Audit Committee relies upon advice and information received in its discussions with our management and independent registered public accounting firm.

The Audit Committee has (i) reviewed and discussed our audited consolidated financial statements for the fiscal year ended September 30, 2010 with our management; (ii) discussed with PricewaterhouseCoopers LLP, our independent registered public accounting firm, the matters required to be discussed by Statement on Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board in Rule 3200T, regarding communication with audit committees; and (iii) received the written disclosures and the letter from our independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence, and has discussed with PricewaterhouseCoopers LLP their independence.

Based on the review and discussions with management and our independent registered public accounting firm referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2010 for filing with the SEC.

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview

The compensation program goals for our Named Executives (whom we refer to as Executives elsewhere) identified on the Summary Compensation Table on page 20 are to incent profitable growth and create long-term value for our shareholders. Our “pay-for-performance” compensation programs reward sustained financial and operating performance and the creation of shareholder value, align the interests of our Executives with those of our shareholders, support retention goals, and attract qualified executive talent.

Compensation elements are designed to simultaneously fulfill one or more performance, alignment, attraction and retention objectives. Direct compensation elements consist of base salary, annual and quarterly cash incentive and equity incentive compensation. We place great emphasis on the opportunity for incentive compensation, thus aligning total direct compensation with the performance of the Company.

Our Compensation Committee (whom we refer to as Committee elsewhere), composed of three independent, non-employee directors, discharges board of directors’ responsibilities with respect to all forms of compensation for Executives as well as general oversight of compensation plans. The Committee has the authority to retain outside counsel, experts and other advisors as it determines appropriate.

Compensation Elements and Objectives

Base salary

Base salaries need to be competitive to attract and retain key talent. Base salaries for our Executives depend on the level of their responsibilities, management experience and performance against strategic objectives, level of contribution to the business, internal rates for comparable positions, and external market rates for comparable positions within our peer and/or survey group. Base salaries are reviewed annually but not automatically increased. Adjustments are approved by the Committee based upon changes in competitive market data and the other factors noted above, or for changes in responsibilities due to promotion. Base salary levels reflect the Committee’s compensation philosophy of favoring compensation that is contingent on the achievement of performance objectives while providing a level of salary that will support our goals of attracting and retaining talent.

Cash Incentives

Cash incentives reward Executives for achievement of financial goals and other key strategic measures. Cash incentives range from 35% to 50% of an Executive’s total cash compensation target, and therefore, provide significant incentive for the achievement of annual financial goals.

This cash incentive program provides the opportunity to receive quarterly and annual cash incentive payments depending on the degree to which we achieve quarterly and annual financial goals. This incentive is typically divided into one or more specific financial metrics. Each metric has a minimum threshold of performance against goal required for any payment, and a maximum payment opportunity. Cash incentives are paid annually following the release of our audited consolidated financial statements. Quarterly incentives are paid quarterly upon the release of our quarterly unaudited consolidated financial statements.

Cash incentive plan metrics and potential cash incentive amounts are determined by the Committee near the start of each fiscal year based upon elements of our board-approved business plan for that year and, in some years, have included other objective measurements of quarterly or annual financial success as the Committee determines to approve. The Committee approves plan elements and targets that they believe will support continued growth and creation of shareholder value.

The annual cash incentive component pays out based on performance and only if the executive remains employed with us for the full year. (In the event an executive is terminated without cause during the year, a pro-rated cash incentive is earned based on the number of months of service during the year and our actual financial performance against plan.)

From time to time, the Compensation Committee has also awarded discretionary cash bonuses based upon its assessment of an executive’s performance and contributions, and may do so in the future.

Table of Contents

Equity Incentive Compensation

Equity incentive compensation, in the form of stock options, is designed to reward demonstrated performance and leadership, motivate future superior performance that drives overall Company growth, align the interests of the Executive with our shareholders, and allow us to attract and retain talent through the long-term reward potential of this program. We currently provide non-statutory stock options as our only equity vehicle. Stock option awards are made to Executives annually and on other dates that correspond to the executive’s start date with us, promotions or, in rare cases, an extraordinary performance award. Stock option grant amounts have historically been based upon competitive equity compensation within our peer group and/or survey group along with individual factors listed above. Existing ownership levels are generally not a factor in award determinations as we do not want to discourage Executives from accumulating Digi stock; however, the Committee may take into consideration an Executive’s previous option awards and approve larger awards to newer Executives with fewer options by reason of their shorter tenure.

Stock options have an exercise price equal to the closing sale price of a share of Digi common stock on the grant date. As a result, stock options only have value to the extent the price of Digi stock on the date of exercise exceeds the exercise price on grant date. For this reason the Committee believes that stock options are a motivational tool to drive shareholder value.

Generally stock options granted become exercisable as to one-fourth of the shares beginning one year after the grant date and in 36 monthly installments as to the remainder, and have a maximum ten-year term. This vesting schedule aids us in retaining executives and motivating long-term performance. Under our current practice, options awarded to our Executives include a provision for accelerated vesting upon the permanent disability or death of the executive or upon a change in control. From time to time, at the discretion of the Compensation Committee, a stock option grant may contain different terms for vesting or term if the Committee deems, that by doing so, we will better achieve our compensation objectives.

Other Compensation

We provide our Executives with perquisites and benefits that we believe are reasonable and aligned with our overall executive compensation program objectives. Executives receive the same benefits that are available to all regular full-time employees with the sole addition of a supplemental life insurance policy. Executives, along with other regular full-time employees, may be entitled to the use of Company paid tickets to sporting events.

We may enter into severance arrangements with Executives to align their interests with shareholders and attract and retain executives by providing contractual arrangements that address the consequences of significant organizational changes.

Compensation Determination Process

There is no specific formula used to determine the mix of compensation components. The Compensation Committee designs the mix of short-term cash compensation and long-term equity compensation to be commensurate to the level of responsibility of the Executive. The factors the Committee considers when determining total compensation plans and targets include, but are not limited to, the following:

| • | Compensation levels of comparable jobs at companies in our targeted peer group and
our broad technology industry category with comparable annual revenues, and
compensation of each Executive relative to that of our other executives other than our
Chief Executive Officer; |
| --- | --- |
| • | Executive’s performance against annual objectives; |
| • | The qualifications of the Executive and the potential for development and
performance in the future; |
| • | The portion of total compensation that should be performance-based; |
| • | The strategic goal achievement to which the Executives are held accountable; |
| • | The recommendations of the Chief Executive Officer (except with respect to his own
compensation); and |
| • | Current financial conditions and goals of the Company. |

Table of Contents

The Compensation Committee reviews the overall executive compensation program and specific compensation elements each year. The Committee begins this review process by determining the total cash compensation and equity incentive compensation to be paid to an Executive based on the factors listed above along with a review of the executive pay levels for comparable jobs as described below.

To determine competitive compensation for comparable jobs, the Committee reviews compensation data for a targeted group of peer companies. The Committee may also consider third party survey data of companies in our broad technology industry category with comparable annual revenues.

Digi does not set specific market percentile targets for base salary and cash incentives for Executives. After determining total cash compensation targets based on the factors listed above, our Committee determines the appropriate mix of base salary, cash incentive and equity incentive compensation for each Executive. Our pay-for-performance philosophy results in total cash compensation plans more leveraged towards cash incentive compensation than base salary. For Executives, base salaries comprise 50% to 65% of total cash compensation targets. As a result, our base salaries can fall below the median base salary of our peer group. Total cash compensation, when earned, will result in Executive total cash compensation falling on average between the peer group median and 75th percentile. Actual total cash compensation for Executives has fallen close to the 25th percentile for the past three years. This is a result of performance targets not being met, or in the case of fiscal 2009, the incentive plan being cancelled for the majority of the year.

The Committee awards stock options to Executives based on the following factors,

| • | The value of equity awards within our peer group for comparable positions. The
Committee considers ranges of equity between the 25th and 75th percentile, |
| --- | --- |
| • | Executive’s past performance and potential for Executive to contribute to Company
success in the future, and |
| • | The strategic impact of the Executive’s position and necessity to retain Executive. |

Actual stock option awards for Executive in fiscal 2011 and fiscal 2010 have fallen between peer group 50th and 75th percentile.

Fiscal 2010 Compensation

For fiscal year 2010, the Committee reviewed the base salary, annual cash incentives and long-term equity incentive elements and levels for our Executives after consideration of the competitive analysis report as prepared by our Vice President of Human Resources. This report contained competitive data on base salaries, annual cash incentives and long-term equity incentives from a peer group and a survey group. The peer group was originally defined in 2007 through an independent analysis and recommendation from Pearl Meyer & Partners and modified annually to reflect company data that was no longer available. The peer group selection process was based on criteria defined by Pearl Meyer & Partners, namely strong technology industry/product similarity, annual revenues, and market capitalization. The 2010 peer group consisted of Acme Packet, Adaptec, Adtran, Avocent, Communication Systems Inc., Extreme Networks, Foundry Networks, Network Engines, Network Equipment Technologies, and Pctel. The survey group contained data as reported by Radford and Associates, an independent third party compensation survey that the Company subscribes to. This survey data contained competitive information for high technology companies in our broad industry category and within a revenue range of $100 to $200 million. The Committee considered this information, in addition to the factors described above, to determine the appropriate base salary, annual cash incentives and equity incentive awards and when setting the corresponding compensation levels to be paid to Executives for fiscal 2010.

Fiscal 2011 Compensation

For fiscal 2011, the Committee reviewed a competitive analysis of the base salary, annual cash incentives and equity incentive elements and levels for our Executives. This assessment was compiled and presented by Pearl Meyer & Partners, the Committee’s independent compensation consultant. This assessment consisted of:

  1. A review of our fiscal 2010 peer group and industry review to assess whether modifications were appropriate based on changes in the industry. As a result of this review, Pear Meyer & Partners recommended a modified peer group which was approved by the Compensation Committee. Peer

Folio 13 /Folio

Table of Contents

group companies were recommended based on strong technology/industry similarity, annual revenues and market capitalization. The fiscal 2011 peer group consists of the following companies:

Adaptec, Inc. Network Engines, Inc.
Anaren Inc. Network Equipment Technologies, Inc.
BigBand Networks, Inc. Neutral Tandem, Inc.
CalAmp Corp. Oplink Communications, Inc.
Communications Systems Inc. Orbcomm, Inc.
Echelon Corp. Seachange International, Inc.
EMS Technologies Inc. Shoretel, Inc.
Extreme Networks Inc. Sierra Wireless, Inc.
Globecomm Systems, Inc. Silicon Laboratories, Inc.
Ixia Symmetricom, Inc.
  1. A comparison of our compensation elements and levels against the fiscal 2011 peer group to determine our overall market percentile position on each element as well as our total cash compensation and total equity compensation. The Committee considered this data, in addition to the factors described above prior to making compensation decisions for fiscal 2011.

Equity Grant Practices

The exercise price of each stock option awarded to the Executives and other employees under our equity incentive plans is the closing price of Digi stock on the date of grant, which, for Executives, is the November Committee meeting date that follows the public announcement of our year-end results. Equity awards for other employees are generally made at the same time, although awards for new hires and for promotions and other performance-related awards are also made during the course of the year. Board and Committee meetings are generally scheduled several months in advance with regard to anticipated earnings announcement schedules as grants are only made when the Company’s trading window is open. Scheduling decisions are made without regard to anticipated earnings or other major Company announcements.

Management Participation

Members of executive management participate in Committee meetings at the Committee’s request. Management’s role is to contribute input and analysis to the Committee’s discussions. Management does not participate in the final determination or recommendation of the amount or form of executive compensation, except that our Chief Executive Officer does participate in the final recommendation discussion, but not determination, of the amount and form of compensation to be paid to the other Executives.

Use of Consultants

From time to time, as noted above, the Compensation Committee uses outside compensation consultants to assist it in analyzing our compensation programs and determining appropriate levels of compensation and benefits. The decision to retain consultants and, if so, which consultants to retain, is made solely by the Committee.

In fiscal 2010, the Compensation Committee retained Pearl Meyer & Partners as its outside compensation consultant. Company management also purchases third party survey data from Pearl Meyer & Partners, the value of which is below $7,500 per year.

Compensation of Chief Executive Officer in Fiscal 2010

The specific compensation paid to our Chief Executive Officer for fiscal 2010 reflects our performance against key financial measurements established by the Compensation Committee at the beginning of the year. A more detailed analysis of our financial and operational performance is contained in the Management’s Discussion & Analysis section of our 2010 Annual Report on Form 10-K filed with the SEC.

Base Salary

Mr. Dunsmore’s annual base salary for fiscal 2010 was set at $406,000, with no increase over his fiscal 2009 base salary.

Annual Cash Incentive

Mr. Dunsmore’s employment agreement dated September 27, 2006 fixed his cash incentive target at not less than 100% of his base salary. Mr. Dunsmore’s cash incentive target based on financial objectives was set by the Committee at $406,000 with additional incentives described below for financial performance in excess of plan and acquisitions.

For fiscal 2010, the Committee set a cash incentive plan based on performance against financial and strategic goals. This plan included both quarterly and annual cash incentive opportunity, an excess revenue component and an acquisition component.

Quarterly Performance Objectives (target and maximum of $30,450 per quarter). Mr. Dunsmore earned the following cash incentive payment for quarterly performance during 2010. This Quarterly Financial Objective component was dependent on achievement of quarterly revenue goals, which were deemed to be aggressive but attainable. There was a minimum of 85% achievement required to earn payment, with maximum payment of 100% for each quarter.

Quarter Ended Revenue Goal (in 000’s) Actual Revenue (in 000’s) Incentive Payment
12/31/2009 $ 41,600 $ 42,968 103.3 % $ 30,450
3/31/2010 $ 42,500 $ 45,076 106.1 % $ 30,450
6/30/2010 $ 46,400 $ 47,238 101.8 % $ 30,450
9/30/2010 $ 47,500 $ 47,266 99.5 % $ 30,146
Total Incentive Paid $ 121,496

Annual Financial Objectives (target and maximum of $284,200). The annual financial objective component was based on the Company’s achievement of annual organic EBTDA targets. Payment of this component began upon exceeding annual organic EBTDA goals, with target payment achieved upon the Company exceeding its annual organic EBTDA goal by 22.9%. This component was deemed difficult to achieve, as it required financial performance well above the Company’s annual operating plan. There was no payment earned under this component of the annual cash incentive plan.

EBTDA can be calculated from our audited financial statements by adding depreciation of property, equipment and improvements plus amortization of identifiable intangible assets and other assets, both of which are located on the Consolidated Statements of Cash Flows, to income before income taxes, located on the consolidated Statements of Operations. Organic EBTDA is calculated by subtracting that portion of EBTDA pertaining to income before income taxes, depreciation and identifiable intangible assets amortization for businesses acquired in the current fiscal year from the consolidated EBTDA.

Excess Financial Performance Component

Another feature of Mr. Dunsmore’s cash incentive plan for fiscal 2010 was the possibility of an additional bonus of up to 50% of his annual cash incentive target based upon a scale for the achievement of organic EBTDA beginning at 23% above annual plan. Maximum payment of additional 50% under this component would be made for achievement at 45.8% above annual plan. There was no payment earned under this component of the annual cash incentive plan.

Acquisition Incentive Component

Mr. Dunsmore also had the opportunity for an additional incentive opportunity based upon the completion of acquisitions meeting certain strategic and performance standards. The program provides for a bonus ranging up to 75% of his annual cash incentive target. As there were no acquisitions in FY2010, no incentive payment was earned under this component.

Equity Incentive Compensation

Mr. Dunsmore received an option award in fiscal 2010 in the amount of 185,000 shares. This award was equivalent to the 50th percentile of fiscal 2010 peer group equity awards.

Compensation of Chief Financial Officer and other Executives in fiscal 2010

Base Salary and Annual Cash Incentive Targets

Mr. Krishnan. For fiscal 2010, Mr. Krishnan’s base salary was increased to $260,000 from $241,500 and his annual cash incentive target was set at $208,000 down from the previous target of $241,500. This modification in plan mix and decrease in total compensation target was made to better align with predominate market practices for similar positions.

Mr. Kraft. For fiscal 2010, Mr. Kraft’s annual base salary remained at $226,500 and his annual cash incentive target remained at $226,500.

Mr. Young. For fiscal 2010, Mr. Young’s annual base salary remained at $234,000 and his annual cash incentive target remained at $187,500.

Annual Cash Incentive Plan

For fiscal 2010, the Committee set an annual cash incentive plan based on performance against quarterly financial and strategic goals for Messrs. Krishnan, Kraft and Young. This plan included quarterly incentive opportunity, an annual excess financial component based on EBTDA results and an acquisition component. The plan components and targets were identical to Mr. Dunsmore’s plan.

Mr. Krishnan’s cash incentive payment of $31,200 was based on the quarterly financial component achievement through the six months ended March 31, 2010. Target incentive for the quarterly component for this same period was $31,200. Mr. Krishnan resigned from the Company on May 7, 2010.

Mr. Kraft’s cash incentive payment of $67,782 was based on the quarterly financial component achievement. Mr. Kraft’s target incentive for the quarterly component of the Annual Cash Incentive Plan was $67,952.

Mr. Young’s cash incentive payment of $56,111 was based on the quarterly financial component achievement. Mr. Young’s target incentive for the quarterly component of the Annual Cash Incentive Plan was $56,252.

Mr. Krishnan, Mr. Kraft and Mr. Young did not receive any cash incentive payments based on the annual financial objectives, excess financial performance component or the acquisition incentive component.

Brenda Mueller, our Corporate Controller, was named Acting Principal Financial Officer and Acting Principal Accounting Officer on May 7, 2010. This assignment and consequent status as a named executive officer was deemed temporary until a permanent Chief Financial Officer took office. During the period of Ms. Mueller’s service as Acting Principal Financial Officer and Acting Principal Accounting Officer, the Compensation Committee took no action with regard to Ms. Mueller’s base salary. As an executive of the Company, Ms. Mueller’s compensation is determined in accordance with the same pay-for-performance philosophy, and is comprised of the same basic elements (base salary, annual cash incentives and stock option awards) as is described elsewhere for our other executive officers. Our Chief Executive Officer determined her base salary, and corresponding cash incentive compensation target, for fiscal 2010 at the outset of the year, before she temporarily became an executive officer. The Compensation Committee approved the grant of option awards to her, as it does for all other optionees. All option awards were made to her at a time when she was not an executive officer of the Company and were in amounts proposed by management as being commensurate with the Corporate Controller position. Her cash incentive opportunity was likewise developed by management before she became Acting Principal Financial Officer and Acting Principal Accounting Officer. At the outset of fiscal 2010, the Compensation Committee also approved the cash incentive plan structure that applied to her, but not the amount of her cash incentive compensation target of 30% of her base salary. For fiscal 2010, 50% of Ms. Mueller’s annual cash incentive was based on the same EBTDA objectives as those described for the other executive officers, and the remaining 50% was based on individual performance. The Compensation Committee determined that Ms. Mueller met the individual performance component of her fiscal 2010 cash incentive plan and received a payment of $24,759, and further determined to award her a $10,000 discretionary cash bonus in recognition of her service as our Acting Principal Financial Officer and Acting Principal Accounting Officer. She is not party to any employment or severance agreement with the Company.

In fiscal 2010, Mr. Krishnan received an option award of 50,000 shares. Mr. Kraft and Mr. Young each received a stock option award of 65,000 shares. These awards fell at or below the 50th percentile of the fiscal 2010 peer group equity awards of comparable positions and were determined based on the factors listed above for equity incentive award determination.

Compensation of Chief Executive Officer for Fiscal 2011

Overview

The combination of base salary and annual cash incentive compensation for financial objectives, if paid at target, would put Mr. Dunsmore’s compensation at approximately the 65h percentile relative to the market as determined by the annual competitive assessment.

Base Salary

For fiscal 2011, Mr. Dunsmore’s annual base salary was increased to $422,250, an increase of 4%. This increase was based on peer group competitive data and Mr. Dunsmore’s performance against objectives.

Annual Cash Incentive

For fiscal 2011, Mr. Dunsmore’s annual cash incentive has been set at 100% of base salary, or $422,250, per the terms of his employment agreement.

Forty percent (40%) of Mr. Dunsmore’s annual cash incentive is based on achievement of quarterly revenue and EBTDA objectives. These quarterly objectives, approved by the Committee, are considered confidential commercial and financial data, the disclosure of which would result in competitive harm to the Company. The quarterly objectives were determined after taking into account historical seasonal patterns in quarterly performance and projected revenue opportunity. These targets were set to be aggressive, but attainable. There is an 80% minimum achievement required to earn any payment for this component and a maximum payment of 120%.

The remaining sixty percent (60%) of Mr. Dunsmore’s annual cash incentive is based on achievement of annual revenue and EBTDA targets as approved by the Committee. The Committee considers the annual objectives confidential commercial and financial data, the disclosure of which would result in competitive harm to the Company. The annual targets, which are a sum of the quarterly objectives, are deemed to be aggressive, but attainable. There is an 80% minimum achievement required to earn any payment for this component and a maximum payment of 200%.

Equity Incentive Compensation

On November 23, 2010, Mr. Dunsmore received a stock option award of 190,000 shares.

Compensation of Chief Financial Officer and other Executives for fiscal 2011

Base Salary and Annual Cash Incentive Targets

Mr. Kraft. For fiscal 2011, Mr. Kraft’s annual salary and cash incentive target were increased by 5% to $237,750 each. This increase was based on peer group competitive data and Mr. Kraft’s performance against objectives.

Mr. Young. For fiscal 2011, Mr. Young’s annual salary was increased by 3% to $241,000 and his cash incentive target increased by 3% to $193,000. This increase was based on peer group competitive data and Mr. Young’s performance against objectives.

The combination of base salary and annual cash incentive compensation for financial objectives, if paid at target, would put Messrs. Kraft and Young’s compensation at approximately the 75h percentile relative to the market as determined by the annual competitive assessment.

Annual Cash Incentive

The annual cash incentive compensation of Messrs. Kraft and Young for fiscal 2011 will be determined by achievement against quarterly and annual financial objectives established at the beginning of the year. Messrs. Kraft and Young have identical annual cash incentive goals and percentage weightings and payment criteria as those of Mr. Dunsmore described above.

Equity Incentive Compensation

Messrs. Kraft and Young each received a stock option award on November 23, 2010 for 70,000.

Ms. Mueller’s temporary status as Acting Principal Financial Officer and Acting Principal Accounting Officer continued into fiscal 2011. On November 30, 2010, Steven Snyder will join the Company as our Chief Financial Officer, and at that time Ms. Mueller will revert to her former position of Corporate Controller, and will no longer be an executive officer of the Company. During the period of Ms. Mueller’s service as our Acting Principal Financial Officer and Acting Principal Accounting Officer, the Compensation Committee took no action with regard to Ms. Mueller’s base salary. Her compensation for fiscal 2011 is determined in accordance with the same pay-for-performance philosophy, and is comprised of the same basic elements (base salary, annual cash incentives and stock option awards). For fiscal 2011 the Compensation Committee approved the cash incentive plan for Ms. Mueller, which is comprised of the following elements: (1) 25% based on the same annual revenue objectives, (2) 25% based on the same EBTDA objectives, as those described for the other executive officers, and (3) 50% based on individual performance.

On November 23, 2010 she received a stock option award for 6,000 shares, in an amount proposed by management as being commensurate with the Controller position.

Employment Agreements and Change-in-Control Provisions

As discussed in greater detail under “Employment Contracts; Severance; Termination of Employment and Change-in-Control Arrangements” on page 24, Digi and our Chief Executive Officer, Mr. Dunsmore, are parties to an employment agreement. That agreement provides that, if we terminate Mr. Dunsmore’s employment without cause: (1) he will receive a lump sum equal to one year’s base salary and commencing 12 months after termination, he will receive base salary payments for an additional year (for a total of two years); and (2) in addition to the base salary continuation for two years, Mr. Dunsmore will receive a pro rata bonus based on the number of months that he was employed by us during the year in which his employment was terminated and our actual performance against the annual objectives set by the Committee. Mr. Dunsmore’s stock options vest upon a change in control of our Company.

We also have severance agreements with our other Executives. See “Employment Contracts; Severance; Termination of Employment and Change-in-Control Arrangements” on pages 24-25. Each of these Executives has a letter agreement that provides that if his employment is terminated by us without cause at any time, he will be entitled to receive severance equal to one year’s base salary and a bonus (if earned) that will be based on the number of months of service during the fiscal year and our actual financial performance against plan as determined through their annual cash incentive compensation plan.

Mr. Krishnan’s stock options provided for accelerated vesting upon a change in control of our Company, and the options granted to Messrs. Young and Kraft on or after November 26, 2007 also provide for accelerated vesting upon a change in control of our Company.

Accounting and Tax Impacts of Executive Compensation

Section 162(m) of the Internal Revenue Code generally precludes a public corporation from taking a federal income tax deduction for compensation paid in excess of one million dollars per year to certain covered officers. Under this section, compensation that qualifies as performance-based is excludable in determining what compensation amount shall qualify for tax deductibility.

Our Compensation Committee considers our ability to fully deduct compensation in accordance with the one million dollar limitations of Section 162(m) in structuring our compensation programs. However, the

Folio 18 /Folio

PAGEBREAK

Table of Contents

Compensation Committee retains the authority to authorize the payment of compensation that may not be deductible if it believes such payments would be in the best interests of us and our shareholders.

None of our Executives has ever been compensated in a manner that would be non-deductible under Section 162(m), although for fiscal 2010 and 2011 the Committee established performance-based goals for our Chief Executive Officer which, if achieved, would result in annual base salary and other cash compensation exceeding the one million dollar deductible maximum.

Report of the Compensation Committee

The Compensation Committee has reviewed the Compensation Discussion and Analysis and discussed that Analysis with management. Based on its review and discussions with management, the Committee recommended to our Board of Directors that the Compensation Discussion and Analysis be included in Digi’s Annual Report on Form 10-K for the year ended September 30, 2010 and Digi’s 2010 proxy statement. This report is provided by the following independent directors, who comprise the Committee:

(1) Represents the difference between the market value of the shares acquired upon exercise and the aggregate exercise price of the shares acquired.

Employment Contracts; Severance; Termination of Employment and Change-in-Control Arrangements

Joseph T. Dunsmore. We and Mr. Dunsmore are parties to an employment agreement dated September 27, 2006, which set the minimum level of Mr. Dunsmore’s base salary at $375,000 and provides that if we terminate Mr. Dunsmore’s employment without cause he will receive: (1) his base salary for two years; and (2) a pro rata bonus based on the number of months that he was employed by us during the year in which his employment was terminated and our actual performance against the annual objectives set by the Committee.

The employment agreement also provides that the Committee will review Mr. Dunsmore’s base salary annually and may, in its sole discretion, increase it to reflect performance and other factors. Under the employment agreement, Mr. Dunsmore is entitled to a cash bonus equal to 100% of his base salary, provided that the objectives set by the Committee are met. If some or all of the objectives are not met for a fiscal year, then the Committee shall determine in its discretion what portion of the target bonus amount, if any, will be paid to Mr. Dunsmore. If the objectives set by the Committee for a cash performance bonus are exceeded for a fiscal year, the Committee may, in its discretion, award Mr. Dunsmore a bonus in addition to any other bonus to which he is otherwise entitled.

The employment agreement also provides that Mr. Dunsmore is entitled to the benefits and perquisites which we generally provide to our other employees under our applicable plans and policies. The vesting of stock options awarded to Mr. Dunsmore accelerates upon a change-in-control of our company or termination of employment due to death or disability.

Subramanian Krishnan. We and Mr. Krishnan were parties to a letter agreement dated March 26, 1999, as amended, which provided that if Mr. Krishnan’s employment were terminated by us without cause at any time, he would have been entitled to receive severance equal to one year’s base salary and a bonus (if earned) that would have been prorated for the portion of the fiscal year through the termination date. The vesting of stock options awarded to Mr. Krishnan would have accelerated upon a change-in-control of our company or termination of employment due to death or disability. Mr. Krishnan’s employment with the Company ended on May 7, 2010. No payments were made to Mr. Krishnan under this agreement in connection with his departure and the Company has no further obligations under this agreement.

Lawrence A. Kraft. We and Mr. Kraft are parties to a letter agreement dated July 30, 2007. Under this agreement, if Mr. Kraft’s employment is terminated by us without cause at any time, he will be entitled to receive severance equal to twelve months’ base salary and a prorated bonus based on the number of months worked during the year in which his employment was terminated, and our achievement of target goals at the time of the termination. The vesting of stock options awarded to Mr. Kraft accelerates upon his termination of employment due to death or disability. Stock options awarded to Mr. Kraft since November 2007 accelerate vesting upon a change-in-control of our company.

Joel K. Young. We and Mr. Young are parties to a letter agreement dated July 30, 2007. The letter agreement provides that if Mr. Young’s employment is terminated by us without cause at any time, he will be

entitled to receive severance equal to twelve months’ base salary and a prorated bonus based on the number of months worked during the year in which his employment was terminated, and our achievement of target goals at the time of the termination. The vesting of stock options awarded to Mr. Young accelerates upon his termination of employment due to death or disability. Stock options awarded to Mr. Young since November 2007 accelerate vesting upon a change-in-control of our company.

Potential Payments Upon Termination or Change in Control

The table that follows provides the estimated payments and benefits that would be provided to our Named Executives or their beneficiaries under the employment agreements and equity compensation plans described above under various scenarios involving a termination of employment and/or a change in control, and assuming that the event(s) occurred on September 30, 2010. For these purposes, “cause” generally refers to acts by an executive that result in a felony conviction, willful non-performance of material employment duties, or willfully engaging in fraud or gross misconduct that is materially detrimental to our financial interests. As an interim officer, Ms. Mueller is not eligible for payments upon termination or change in control.

other Named Executives with one year of base salary.
(3) Pro rata bonus is based on the number of months that the individual was employed during the
year in which his employment was terminated and our actual performance against the annual
objectives set by the Committee. For purposes of this presentation, since the assumed date of
termination was September 30, 2010, the bonus amount shown is the actual cash incentive earned
for all of fiscal 2010.
(4) Amounts represent the intrinsic value of stock option awards as of September 30, 2010 for

fiscal year), and the option exercise price.

COMPENSATION OF DIRECTORS

In January 2010, in the exercise of its discretion, the Committee awarded annual option awards to non-employee directors per the compensation plan for non-employee directors, as modified in January of 2008. Options awarded become fully vested after one year. Other than in the case of an outside director who is elected at other than an annual meeting, options are awarded to directors at a regularly scheduled meeting of the Committee in January following the annual meeting of stockholders and the public announcement of first quarter financial results. The Committee presently expects to continue to make a one-time stock option award to any newly elected director, as well as to continue to compensate newly elected directors ratably for service during any stub term. In January 2009, the compensation plan for directors was modified to include a $5,000 fee to be paid to the Lead Director.

The Committee conducts periodic competitive reviews of the compensation plan of non-employee directors. The current program is designed to provide non-employee directors with a non-elective combination of cash and options that have a targeted annual aggregate value ranging from approximately $90,000 to $120,000 per director depending on committee service. Based on the 2008 competitive analysis provided by Pearl Meyer & Partners, we believe that this compensation puts Digi within the 50 th to 65 th percentile relative to its peer group (described above). The following table describes the compensation arrangements with our non-employee directors during fiscal 2010.

(1) The “Option Awards” column presents the aggregate grant date fair value of stock option awards granted to each non-employee director during fiscal 2010 as computed in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718, Compensation — Stock Compensation. The fair value of each stock option award is estimated on the date of grant using a Black-Scholes option valuation model. We calculated these amounts based on the grant date fair value of the awards using the valuation assumptions set forth in Note 11 to our fiscal 2010 audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2010. The amounts reported have been adjusted to eliminate service-based forfeiture assumptions used for financial reporting purposes. Information regarding the stock option awards made to the non-employee directors during fiscal 2010, and their aggregate option awards outstanding at September 30, 2010, is contained in the following table:

Stock Option Awards. All options granted to non-employee directors have an exercise price equal to the fair market value of our Common Stock on the date of grant. Options granted become fully vested on the date of the annual meeting of stockholders the year following the date of grant.

RELATED PERSON TRANSACTION APPROVAL POLICY

Our Board of Directors has adopted a written policy (the “Related Person Transaction Approval Policy”) regarding transactions with any “Related Person,” which is defined to include any of our directors or nominees for directors, executive officers and greater than five percent stockholders and any of their respective immediate family members. In accordance with the policy, the Audit Committee is responsible for the review and approval or

Folio 27 /Folio

Table of Contents

ratification of all transactions with Related Persons that are required to be disclosed under the rules of the Securities and Exchange Commission.

The Related Person Transaction Approval Policy covers “Related Person Transactions” (as defined below) between us and any Related Person. Related Person Transactions include any transactions, arrangements or relationships involving the payment of money or other value involving us and in which a Related Person has a direct or indirect interest. A Related Person Transaction does not include:

| • | payments of compensation to Related Persons for the Related Person’s service to us
as a director, officer or employee; |
| --- | --- |
| • | transactions available to all employees or all stockholders on the same terms; or |
| • | transactions, which when aggregated with the amount of all other transactions
between us and the Related Person or any entity in which the Related Person has an
interest, involve less than $120,000 in a fiscal year. |

The Audit Committee must approve a Related Person Transaction prior to commencement of the transaction, except where the transaction is identified after it has commenced or first becomes a Related Person Transaction, in which case the Related Person Transaction will be brought before the Audit Committee for ratification. Our executives are responsible for disclosing all material information pertaining to any Related Person Transaction to the Audit Committee prior to entering into the transaction. The Audit Committee Chairperson has been granted the authority to approve transactions that arise between Audit Committee meetings provided that any actions taken by the Chairperson pursuant to such authority must be reported to the Audit Committee at its next regularly scheduled meeting.

While the Audit Committee is permitted to use any factors it deems appropriate in determining whether to approve a Related Person Transaction, the Related Person Transaction Approval Policy requires the Audit Committee, at a minimum, to consider:

• the fairness of the terms to us;
• materiality of the transaction to us;
• the role of the Related Person in arranging the Related Person Transaction;
• the structure of the Related Person Transaction; and
• the interests of all Related Persons in the Related Person Transaction.

The Audit Committee will only approve a Related Person Transaction if the Committee determines it is beneficial and fair to us.

Related Person Transaction

During fiscal 2010, Digi purchased exclusively through independent third party distributors in the ordinary course of business an aggregate of approximately $243,000 of Spansion Inc. components. Mr. Nawaz, who has served as a director of our company since October 2006, was Executive Vice President of Worldwide Sales, Marketing and Corporate Development of Spansion Inc. until October 2010, when he became Executive Vice President, Wireless Solutions Group at Spansion Inc. The Audit Committee evaluated the transactions and approved them under the Related Person Transaction Approval Policy. The Audit Committee also considered Mr. Nawaz’s interest and determined that he does not have a direct or indirect immaterial interest in the transactions.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the 1934 Act requires that our directors and executive officers file initial reports of ownership and reports of changes in ownership with the SEC. Directors and executive officers are required to furnish us with copies of all Section 16(a) forms they file. Based solely on a review of the copies of such forms furnished to us and written representations from our directors and executive officers, all Section 16(a) filing requirements were met for the fiscal year ended September 30, 2010.

Equity Compensation Plan Not Approved by Stockholders — Digi International Inc. Non-Officer Stock Option Plan

In April 1998, the Board adopted the Digi International Inc. Non-Officer Stock Option Plan (the “Non-Officer Plan”). The Non-Officer Plan has not been approved by the stockholders of the Company.

Plan Administration

The Non-Officer Plan is administered by the Compensation Committee. The Compensation Committee may delegate all or any part of its authority to a one person committee consisting of the Chief Executive Officer of the Company for purposes of granting awards.

Shares Subject to the Non-Officer Plan

As of September 30, 2010, 940,975 shares of the Company’s common stock were subject to outstanding awards granted under this Plan. No shares are available for future award grants, and no additional awards may be made under this Plan. Pursuant to the Non-Officer Plan, the Compensation Committee must adjust the number of shares and the purchase price per share to give effect to adjustments made in the number of outstanding shares of common stock of the Company pursuant to mergers, consolidations, splits, combinations, or other changes in capitalization as described in the Non-Officer Plan.

Eligibility

All employees of the Company and its subsidiaries who are not also officers or directors of the Company, and consultants to the Company or its subsidiaries, were eligible to receive awards under the Non-Officer Plan.

Incentive and Non-Statutory Stock Options

The Non-Officer Plan authorizes the grant of non-statutory stock options. Because the Non-Officer Plan has not been approved by the Company’s stockholders, under the Internal Revenue Code of 1986, as amended, incentive stock options were not granted under the Non-Officer Plan. The exercise price of an option was determined by the Compensation Committee. The exercise price could not be less than 50% of the fair market value, as defined in the Non-Officer Plan, of the Company’s common stock on the date the option is granted. Stock options could be granted and exercised at such times as the Compensation Committee may determine, provided that the term could not exceed ten years from the date of grant. The purchase price for common stock purchased upon the exercise of stock options may be payable in cash, bank draft or money order, by delivery of shares of Company common stock having a fair market value on the date the option is exercised equal to all or any part of the option price of the common stock being purchased or any combination of the above.

Transferability and Termination of Options

The Non-Officer Plan allows the recipient to transfer options to members of his or her immediate family under certain circumstances. Other than such transfers to family members, no option shall be assignable or transferable by the recipient other than by will or the laws of descent and distribution. If a recipient’s employment or other relationship with the Company or its affiliates is terminated for any reason other than death or disability, then any unexercised portion of such recipient’s award will generally be forfeited, except as provided in the Non-Officer Plan or such recipient’s agreement or by the Compensation Committee. Upon death or disability, any unexercised portion of such recipient’s award will automatically vest. Upon a change in control as described in the Non-Officer Plan, the Compensation Committee shall declare all outstanding options cancelled at the time of the change in control in exchange for cash in the amount described in the Non-Officer Plan unless appropriate provisions have been made for the protection of the outstanding options by the substitution of such options for options to purchase appropriate stock of the surviving entity in the change in control.

Adjustments, Modifications, Termination

The Non-Officer Plan gives the Board the right to amend, suspend or discontinue the Non-Officer Plan. Amendments to the Non-Officer Plan are subject to stockholder approval, however, if needed to comply with applicable laws or regulations. The Compensation Committee may generally also alter or amend any agreement covering an award granted under the Non-Officer Plan to the extent permitted by law.

PROPOSAL NO. 2 RATIFICATION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The firm of PricewaterhouseCoopers LLP, independent registered public accounting firm, or one of its predecessors, has been the independent registered public accounting firm for us since 1986. The Audit Committee has again selected PricewaterhouseCoopers LLP to serve as our independent registered public accounting firm for the fiscal year ending September 30, 2011, subject to ratification by the stockholders. While it is not required to do so, the Audit Committee is submitting the selection of that firm for ratification in order to ascertain the view of the stockholders. If the selection is not ratified, the Audit Committee will reconsider its selection.

A representative of PricewaterhouseCoopers LLP will be present at the annual meeting and will be afforded an opportunity to make a statement if such representative so desires and will be available to respond to appropriate questions during the meeting.

Audit and Non-Audit Fees

The following table presents fees for fiscal 2010 and 2009 for professional audit services performed by PricewaterhouseCoopers for the audit of our annual consolidated financial statements, the review of our interim consolidated financial statements for each quarter in fiscal 2010 and 2009 and all other services performed:

Year Ended September 30, — 2010 2009
Audit Fees $ 725,626 $ 615,369
Audit-Related Fees — —
Tax Fees — —
All Other Fees — —
Total $ 725,626 $ 615,369

The Audit Committee pre-approved all of the services described above pursuant to engagements that occurred in fiscal 2010 and 2009.

The Audit Committee’s current practice on pre-approval of services performed by the independent registered public accounting firm is to approve annually all audit services and each recurring permissible non-audit service to be provided by the independent registered public accounting firm during the fiscal year. In addition, the Audit Committee may pre-approve other non-audit services during the year on a case-by-case basis, and delegates authority to grant such pre-approvals during the year between Audit Committee meetings to the Audit Committee Chairman. The Audit Committee reviews each non-audit service to be provided and assesses the impact of the service on the independent registered public accounting firm’s independence.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING SEPTEMBER 30, 2011.
