The Board of Directors (the "Board") of Innovative Solutions and Support, Inc. ("ISS" or the "Company") is soliciting your proxy to vote your shares at the Company's 2011 annual meeting of shareholders. The annual meeting will be held on April 21, 2011 at 10:00 a.m., local time, at the Company's corporate offices at 720 Pennsylvania Drive, Exton, Pennsylvania. ISS intends to mail a Notice of Internet Availability of Proxy Materials (sometimes referred to as the "Notice"), and to make this Proxy Statement available to its shareholders of record entitled to vote at the Annual Meeting, on or about January 27, 2011.

In accordance with the rules and regulations adopted by the Securities and Exchange Commission ("SEC"), instead of mailing a printed copy of the proxy materials to each shareholder of record, the Company may now furnish proxy materials including this Proxy Statement, the proxy card, and the Company's Annual Report on Form 10-K for the year ended September 30, 2010 ("Annual Report") to the Company's shareholders by providing access to such documents on the Internet. Shareholders will not receive printed copies of the proxy materials unless requested. Instead, the Notice will instruct shareholders as to how they may access and review all of the proxy materials. The Notice also instructs shareholders how to submit a proxy through the Internet. If you would like to receive a paper copy or e-mail copy of your proxy materials, you should follow the instructions for requesting such materials included in the Notice. ISS will pay the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials and soliciting votes. If you choose to access the proxy materials and/or vote over the Internet, you are responsible for any Internet access charges you may incur.

You may revoke this proxy at any time before it is voted by written notice to the Chief Financial Officer of the Company, by submission of a proxy bearing a later date or by casting a ballot at the Annual Meeting. Properly executed and delivered proxies that are received before the Annual Meeting's adjournment will be voted in accordance with the directions provided or, if no directions are provided, your shares will be voted by one of the individuals named on your proxy card as recommended by the Board of Directors. If you wish to give a proxy to someone other than those named on the proxy card, you should cross out those names and insert the name(s) of the person(s), not more than three, to whom you wish to give your proxy.

If you want to vote in person at the Annual Meeting and you hold shares of Company common stock in street name, you must obtain a proxy card from your broker and bring that proxy card to the Annual Meeting, together with a copy of a brokerage statement reflecting your stock ownership as of the record date.

You can vote if, as of the close of business on January 21, 2011, you were a shareholder of record of the Company's common stock. On that date, 16,781,260 shares of ISS common stock were outstanding and entitled to vote. The Company does not have any other classes of voting stock outstanding other than ISS common stock. Each share of common stock is entitled to one vote, and there are no cumulative voting rights when voting for directors. A list of shareholders eligible to vote will be available at the offices of Innovative Solutions and Support, Inc., 720 Pennsylvania Drive, Exton, Pennsylvania 19341 beginning January 27, 2011. Shareholders may examine this list during normal business hours for any purpose relating to the Annual Meeting.

If you and other residents at your mailing address own shares of common stock in "street name," your broker or bank may have notified you that your household will receive only one annual report and proxy statement, or one notice of internet availability of proxy materials, as applicable, for each company in which you hold stock through that broker or bank.

This practice is known as "house-holding." Unless you responded that you did not want to participate in "house-holding," you were deemed to have consented to the process. Each shareholder will continue to receive a separate proxy card or voting instruction card.

If you did not receive an individual copy of this year's proxy statement or annual report, ISS will send a copy to you if you address a written request to the Company's Chief Financial Officer, Ronald C. Albrecht, 720 Pennsylvania Drive, Exton, Pennsylvania 19341, telephone (610) 646-9800.

If you would like to receive your own set of the Company's future annual report and proxy statement, or if you share an address with another Company shareholder and together both of you would like to receive only a single set of the Company's annual disclosure documents, you should contact your broker or bank or you may contact the Company at the above address and phone number.

The presence at the annual meeting, in person or by proxy, of shareholders entitled to cast at least a majority of the votes that all shareholders are entitled to cast on a particular matter to be acted upon at the meeting shall constitute a quorum for the purpose of consideration and action on the matter. Abstentions from voting and broker "non-votes" will be counted toward a quorum. A broker "non-vote" occurs when the nominee holding a shareholder's shares does not vote on a particular proposal because the nominee does not have discretionary voting power on that item and has not received instructions from the shareholder.

The nominees for director who receive a plurality of the shares of common stock present or represented by proxy at the annual meeting will be elected. Approval of each other matter to be voted on at the annual meeting requires the affirmative vote of a majority of the votes properly cast at the meeting with respect to such matter. Abstentions or broker "non-votes" will not be counted for or against matters to be acted on at the annual meeting.

The Board does not intend to bring any other matters before the annual meeting except the matters listed in the notice, and the Board is not aware of anyone else who will submit any other matters to be voted on. However, if any other matters properly come before the annual meeting, the people named on the proxy card, or their substitutes, will be authorized to vote on those matters in their own judgment.

Most shareholders have three ways to vote by proxy: by telephone, by the Internet or by returning the proxy card. To vote by telephone or by the Internet, you must follow the instructions set forth on the Notice that you receive. To vote by mail, you must sign and date each proxy card you receive, mark the boxes indicating how you wish to vote and return the proxy card. Do not return the proxy card if you vote by the Internet or by telephone.

Yes. You can change or revoke your proxy at any time before the annual meeting either by notifying the Company's Secretary and Chief Financial Officer in writing or by sending another executed proxy dated later than the first proxy card. Your attendance at the annual meeting will not cause your previously granted proxy to be revoked unless you specifically so request. For shares that you hold beneficially, you may change or revoke your proxy by submitting new voting instructions to your broker or nominee.

Yes. However, the Company encourages you to vote by proxy to ensure that your shares are represented and voted. If you attend the annual meeting in person, you may then vote in person even though you returned your proxy card.

The Company will pay all costs in connection with the meeting, including the cost of preparing, assembling and mailing the notice of the Annual Meeting, proxy statement and proxy card, as well as handling and tabulating the proxies returned. In addition to the use of mail, proxies may be solicited by directors, officers and regular employees of the Company, without additional compensation, in person or by telephone or other electronic means. The Company will reimburse brokerage houses and other nominees for their expenses in forwarding proxy material to beneficial owners of the Company's common stock.

If you have questions about the annual meeting or would like additional copies of this proxy statement, you should contact the Company's Chief Financial Officer, Ronald C. Albrecht, 720 Pennsylvania Drive, Exton, Pennsylvania 19341, telephone (610) 646-9800.

On written request, ISS will provide, without charge, a copy of its annual report on Form 10-K for the year ended September 30, 2010, as amended (including a list briefly describing the exhibits thereto), filed with the SEC, to any record holder or beneficial owner of its common stock on January 21, 2011, the record date, or to any person who subsequently becomes such a record holder or beneficial owner. Requests should be directed to the attention of the Company's Chief Financial Officer at the address set forth above.

The following table sets forth certain information with respect to the beneficial ownership, as of January 21, 2011, of each person who the Company knew to be the beneficial owner of more than 5% of its common stock. To the knowledge of the Company, each of the shareholders named below has sole or shared power to vote or direct the vote of such shares or the sole or shared investment power with respect to such shares, unless otherwise indicated. The information provided in the table is based

on the Company's records, information filed with the Securities and Exchange Commission and information provided to the Company.

The following table sets forth certain information with respect to the beneficial ownership as of January 21, 2011, of (i) each director, (ii) the chief executive officer and each other executive officer, and (iii) all the directors and executive officers as a group. Each of the shareholders named below has sole voting and investment power with respect to such shares, unless otherwise indicated. The information provided in the table is based on the Company's records, information filed with the Securities and Exchange Commission and information provided to the Company.

The following table provides information about ISS common stock that may be issued upon the exercise of options and rights under all of the Company's existing equity compensation plans and arrangements as of September 30, 2010, including the 1998 Stock Option Plan, the 2003 Restricted Stock Plan and the 2009 Stock-Based Incentive Compensation Plan.

The 2003 Restricted Stock Plan for non-employee directors was approved by shareholders at the Company's February 26, 2004 Annual Meeting of Shareholders. The 2003 Restricted Stock Plan called for an annual award of restricted stock having a fair market value of $25,000 as of the close of business on October 1 of the then current fiscal year for all eligible non-employee directors. The stock was awarded in four installments quarterly during the fiscal year provided the director was still serving on the board on the quarterly issue date. In fiscal year 2005 the annual award was increased to $40,000 effective the fourth quarter of the fiscal year.

In the fiscal years ended September 30, 2010, 2009, and 2008, awards issued to non-employee directors under the Plan were 37,862, 29,815 and 11,355 shares respectively.

The Company's 2009 Stock-Based Incentive Compensation Plan (the "2009 Plan") was approved by the Company's shareholders at the Company's Annual Meeting of Shareholders held on March 12, 2009. The 2009 Plan authorizes the grant of Stock Appreciation Rights, Restricted Stock, Options and other equity-based awards under the 2009 Plan. Options granted under the 2009 Plan may be either incentive stock or nonqualified stock options, as determined by the Compensation Committee of the Company's Board of Directors.

Subject to an adjustment necessary upon a stock dividend, recapitalization, forward split or reverse split, reorganization, merger, consolidation, spin-off, combination, repurchase or share exchange, extraordinary or unusual cash distribution or similar corporate transaction or event, the maximum number of shares of common stock available for awards under the 2009 Plan are 1,200,000, all of which may be issued pursuant to awards of incentive stock options. In addition, the 2009 Plan provides that no more than 300,000 shares may be awarded in any calendar year to any employee as a performance-based award under Section 162(m) of the Internal Revenue Code.

The 2009 Plan will terminate on March 12, 2019, unless earlier terminated by the Board. Termination will not affect awards outstanding at the time of termination. The Board may amend, alter, suspend, discontinue or terminate the 2009 Plan without shareholder approval, provided that shareholder approval is required for any amendment which (i) would increase the number of shares subject to the 2009 Plan; (ii) would decrease the price at which awards may be granted; or (iii) would require shareholder approval by law, regulation, or the rules of any stock exchange or automated quotation system.

The Company's 1998 Stock Option Plan was adopted in order to recognize the contributions made by the Company's employees, directors, consultants and advisors, to provide such persons with additional incentives to devote their efforts to the Company's future success and to improve the Company's ability to attract, retain and motivate individuals through the receipt of Company stock options. The maximum number of shares of the Company's stock available under the 1998 Stock Option Plan was 3,389,025 (after giving effect to stock splits). The 1998 Stock Option Plan authorized the grant of "incentive stock options" (within the meaning of Section 422 of the Code) and non-qualified stock options, such options to vest and become exercisable as specified in separate written agreements between the Company and the option recipient. Unless otherwise specified in such agreement, all outstanding options become fully vested and exercisable upon a change in control. The 1998 Stock Option Plan expired on November 13, 2008, therefore no further options can be awarded under the plan.

The Company's 2003 Restricted Stock Plan was adopted in order to provide non-employee directors with restricted stock grants that would encourage them to contribute to the growth of the Company and benefit the Company's shareholders. The maximum number of shares of the Company's stock available under the 2003 Restricted Stock Plan was 1,500,000 (after giving effect to stock splits). Each non-employee director was eligible to receive an award of restricted stock on an annual basis, with such award vesting over the course of the then fiscal year in equal installments. In fiscal years ended September 30, 2010, 2009, and 2008 awards granted to non-employee directors under the 2003 Restricted stock Plan were 41,150, 36,230 and 10,525 shares respectively. As of January 21, 2011, no shares remain available for grants of restricted stock under the Company's 2003 Restricted Stock Plan; however, the Company intends to continue with such annual grants to non-employee directors under the 2009 Stock-Based Incentive Compensation Plan.

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company's officers (as defined under Section 16(a) of the Securities Exchange Act), directors and persons who own greater than 10% of a registered class of the Company's equity securities to file reports of ownership and changes in ownership with the SEC. Based solely on a review of the forms the Company has received and on written representations from certain reporting persons that no such forms were required for them, the Company believes that, during fiscal year 2010, the officers, directors and 10% beneficial owners of the Company complied with all of the applicable Section 16(a) filing requirements.

At the annual meeting, the shareholders will elect two Class II directors and one Class I director to hold office until the annual meetings of shareholders in 2014 and 2013, respectively, or until their respective successors have been duly elected and qualified. The Board is divided into three classes serving staggered three-year terms, the term of one class of directors to expire each year. The term of the Class II directors expires at the 2011 annual meeting of shareholders.

Upon the recommendation of the Nominating/Corporate Governance Committee, the Board has nominated Mr. Glen R. Bressner and Mr. Robert E. Mittelstaedt, Jr. to serve as Class II directors. Both men serve presently as Class II directors and each has indicated a willingness to continue serving as a director. In July 2010, Mr. Robert A. Mionis was elected by the Board of Directors as a Class I director to fill a vacancy on the Board of Directors. According to the Company's bylaws, when a director is elected to fill a vacancy on the Board of Directors, he shall be elected to serve a term expiring at the next annual meeting of shareholders, regardless of the class to which the director is elected. At the next annual meeting of shareholders, that director shall stand for re-election to a term expiring at the annual meeting when the term of a director in such class would naturally expire. Upon the recommendation of the Nominating/Corporate Governance Committee, the Board has nominated Mr. Robert A. Mionis to serve as a Class I director. Mr. Mionis currently serves as a Class I director and has indicated a willingness to continue serving as a director for a term expiring at the annual meeting of shareholders in 2013.

Unless contrary instructions are given, the shares represented by a properly executed proxy will be voted "FOR" the election of Messrs. Bressner, Mittelstaedt and Mionis. Shareholders must cast a separate vote "FOR" or "AGAINST" the candidacy of each nominee. The three nominees receiving a plurality of the votes cast for director will be elected. Should any nominee become unavailable to accept election as a director, the persons named in the enclosed proxy will vote the shares that they represent for the election of such other person as the Board may recommend. The Board of Directors recommends voting "FOR" the nominees for Class I and Class II directors.

The Board of Directors believes that each of the directors and nominees for director listed above has the sound character, integrity, judgment and record of achievement necessary to be a member of the Board of Directors. In additional, each of the directors and nominees for director has exhibited during his prior service as a director the ability to operate cohesively with the other members of the Board of Directors and to challenge and question management in a constructive way. Moreover, the Board of Directors believes that each director and nominee for director brings a strong and unique background and skill set to the Board of Directors, giving the Board of Directors as a whole competence and experience in diverse areas, including corporate governance and board service, finance, management and aviation industry experience. Set forth below are certain specific experiences, qualifications and skills that led to the Board of Directors' conclusion that each of the directors and nominees for director listed above should continue to serve as a director.

Mr. Bressner brings to the Board of Directors a wealth of experience managing financial investments from his service at venture capital firms. Mr. Bressner provides the Board of Directors with a thorough understanding of capital markets and other financial issues. Mr. Bressner's experience in managing investments also provides him with extensive finance and accounting knowledge, and he applies this expertise in his service as chairman of the Audit Committee. Mr. Bressner's prior service as Chairman of the Board of Directors of the Greater Philadelphia Venture Group and on numerous other boards of directors, including of several public entities, also provided him with valuable experience in corporate governance matters, which he draws from in his service on the Audit Committee, the Investment Committee and the Nominating/Corporate Governance Committee.

Mr. Mittelstaedt, having served as the Non-Executive Chairman of the Board of Directors for eight years, provides the Board of Directors with a comprehensive knowledge of the Company and its history. In addition, Mr. Mittelstaedt has extensive academic business experience, having served as Dean of the W.P. Carey School of Business at Arizona State University and Vice Dean at The Wharton School of the University of Pennsylvania. This experience has exposed Mr. Mittelstaedt to contemporary business strategies and practices which he draws from in his service on the Board of Directors. Mr. Mittelstaedt's experience on various other boards of directors provides him with insight into corporate governance which he utilizes in his service on the Compensation and Nominating/Corporate Governance Committees. Additionally, Mr. Mittelstaedt has been a pilot for over 45 years and holds a FAA Commercial Pilot Certificate with Multi-Engine and Instrument ratings. Consequently, he has gained operational experience with state of the art avionics, which he brings to the Board of Directors.

Mr. Hedrick, as founder and Chief Executive Officer of the Company, provides the Board of Directors with a comprehensive knowledge of the Company, its history and its businesses. In addition, Mr. Hedrick brings to the Board of Directors his insight into the aviation industry from over 40 years of leadership experience in executive positions in aviation companies, including Smith Industries plc and Harowe Systems, Inc.

Mr. Churchill brings to the Board of Directors over twenty-five years of experience in private equity investing, during which he gained valuable insight into effective management of investments. Mr. Churchill utilizes this insight to advise the Board of Directors on financial and investment matters. In addition, Mr. Churchill has extensive experience serving on the boards of directors of other companies, both public and private. Mr. Churchill draws on his financial and corporate governance experience in his service on the Audit Committee, the Investment Committee, the Compensation Committee and the Nominating/Corporate Governance Committee. In addition, Mr. Churchill has maintained a pilot's license for nine years and has Instrument and Multi-Engine ratings. Consequently, he has gained operational experience with state of the art avionics, which he brings to the Board of Directors.

Mr. Rau brings to the Board of Directors extensive experience in leadership positions with companies in the aviation industry. From this experience, he has gained in-depth knowledge of the operational issues facing companies in the aviation industry, which he utilizes in advising the Board of Directors. Mr. Rau's prior service on the Board of Governors of the Aerospace Industries Association and as Chairman of both the General Avaition Manufacturers Association and the International Advisory Panel of Singapore Aerospace, has provided him with a unique perspective on the issues facing the aviation industry as a whole, which he draws upon in his service on the Board of Directors.

Mr. Mionis brings to the Board of Directors a comprehensive knowledge of the aviation industry, gained from a long career in various leadership positions with companies in the aviation industry, including StandardAero, Honeywell Aerospace and General Electric Aerospace. Mr. Mionis also provides the Board of Directors with insight into corporate governance matters particular to companies

in the aviation industry through his service on various other boards of directors, including the board of the General Aviation Manufacturers Association.

The Board has determined in its business judgment that five (5) of the Company's six (6) directors are independent as defined in the applicable NASDAQ listing standards, including that each member is free of any relationships that would interfere with his individual exercise of independent judgment. The following directors were determined to be independent: Glen R. Bressner, Winston J. Churchill, Robert A. Mionis, Robert E. Mittelstaedt, Jr. and Robert H. Rau. In 2010, the Board also determined that Mr. Ivan Marks, who served on the Board of Directors until April 21, 2010, was independent as defined in the applicable NASDAQ listing standards.

The Board of Directors does not have a formal policy on whether the roles of Chief Executive Officer and Chairman of the Board of Directors should be separate. Currently, Mr. Geoffrey S.M. Hedrick serves in both of these positions. The Board of Directors believes that it is in the best interests of the Company's shareholders to combine these offices as it promotes information flow between management and the Board of Directors, effective decision making and an alignment of corporate strategy. Mr. Glen R. Bressner, an independent director, serves as Vice Chairman of the Board of Directors and as presiding director during executive sessions of the independent directors. The Board of Directors believes that its structural features, including five independent, non-management directors on a board consisting of six directors, regular meetings of independent directors in executive session, an independent Vice Chairman of the Board of Directors and key committees consisting wholly of independent directors, provide for substantial independent oversight of the Company's management. However, the Board of Directors recognizes that depending on future circumstances, other leadership models may become more appropriate. Accordingly, the Board of Directors will continue to periodically review its leadership structure.

The Company faces a number of risks, including technological and intellectual property risk, regulatory risk, credit risk, liquidity risk, reputational risk and risk from adverse fluctuations in interest rates. Management is responsible for the day-to-day management of risks faced by the Company, while the Board of Directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the Board of Directors seeks to ensure that the risk management processes designed and implemented by management are adequate. The Board of Directors periodically consults with management regarding the Company's risks.

While the Board of Directors is ultimately responsible for risk oversight, the Company's board committees assist the Board of Directors in fulfilling its oversight responsibilities in certain areas of risk. The Audit Committee assists the Board of Directors in its oversight of risk management in the areas of financial reporting and internal controls. The Compensation Committee assists the Board of Directors in oversight of risks related to the Company's compensation policies and programs. The Nominating /Corporate Governance Committee assists the Board of Directors in oversight of risk associated with board organization, membership and structure, succession planning for directors and executive officers and corporate governance.

The Board maintains four standing committees: Audit, Compensation, Investment, and Nominating/Corporate Governance.

Audit Committee. The Audit Committee makes recommendations to the Board with respect to various auditing and accounting matters, including the selection and compensation of the Company's independent registered public accounting firm, the scope of the Company's annual audits, fees to be paid to the independent registered public accounting firm, the performance and independence of the Company's independent registered public accounting firm and the Company's accounting practices. The Audit Committee approves all services provided to the Company by the independent registered public accounting firm. The Audit Committee has established procedures for the receipt, retention and treatment, on a confidential basis, of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and the confidential, anonymous submissions by employees of concerns regarding questionable accounting or auditing matters. In addition, the Audit Committee has responsibility for, among other things, the planning and review of the Company's annual and periodic reports and accounts and the involvement of the Company's independent registered public accounting firm in that process. Messrs. Bressner (Chairman), Rau and Churchill are currently members of the Audit Committee. The Audit Committee is comprised solely of independent members, as independence for audit committee members is defined in the applicable NASDAQ listing standards. In addition, the Board has determined in its business judgment that each member of the Audit Committee is financially literate and that at least one of the Audit Committee members, Mr. Rau, is an audit committee financial expert, as defined by SEC rules and regulations. The Audit Committee has adopted a formal written Charter that has been approved by the Board. The Charter specifies the scope of the Audit Committee's responsibilities and procedures for carrying out such responsibilities. A copy of the Charter is available on the Company's website, www.innovative-ss.com under the heading Investor Relations. Please note that none of the information on the Company's website is incorporated by reference in this proxy statement.

Compensation Committee. The Compensation Committee of the Board of Directors is composed of two directors, Messrs. Churchill (Chairman) and Mittelstaedt, each of whom, in the judgment of the Board of Directors, was found to be "independent" as defined by the applicable NASDAQ listing standards. The Compensation Committee is responsible for setting and administering the policies that govern annual executive salaries, bonuses and stock ownership programs. The Compensation Committee annually evaluates the performance of the Company's Chief Executive Officer and determines or recommends to the full Board the annual base salary, bonus and equity-based compensation for the Chief Executive Officer. The Compensation Committee relies on the recommendations of the Chief Executive Officer, following the Chief Executive Officer's annual performance reviews of other executive officers, in setting annual salaries, bonuses and equity-based compensation for other executive officers.

The Compensation Committee is responsible for reviewing and overseeing the Company's benefit plans and stock option plans for employees, consultants, directors and other compensated individuals, including the Chief Executive Officer. The Compensation Committee has adopted a formal written Charter that has been approved by the Board. The Charter specifies the scope of the Compensation Committee's responsibilities and procedures for carrying out such responsibilities. A copy of the Charter is available on the Company's website, www.innovative-ss.com under the heading Investor Relations.

The Compensation Committee has not retained an outside consultant to advise it regarding Company compensation practices. Instead, the Compensation Committee independently determines the appropriate levels of compensation for executive officers and directors taking into account, among other factors, the performance of such individuals (as determined in annual reviews conducted by the Compensation Committee or the Chief Executive Officer), the Company's financial performance, cost of living, prior compensation practices and recruitment and retention needs. The Compensation Committee relies on the recommendations of the Company's Chief Executive Officer in determining

whether and how much of a discretionary bonus may be paid to the Company's employees (including executive officers) in the event the Company's financial performance exceeds the Board's expectations.

Compensation Committee Interlocks and Insider Participation. No member of the Compensation Committee is a former or current executive officer or employee of the Company. There are no compensation committee interlocks between the Company and any other entity involving the Company or such entity's executive officers or board members.

Investment Committee. The Investment Committee assists the Board of Directors in fulfilling its oversight responsibilities with respect to recommendations pertaining to the investment of excess capital, including with respect to the implementation of the Company's stock repurchase program. Messrs. Churchill (Chairman), Bressner and Rau are currently the members of the Investment Committee.

Nominating/Corporate Governance Committee. The Company has a Nominating/Corporate Governance Committee, consisting of three non-employee directors. The Committee has adopted a formal written Charter that has been approved by the Board. The Charter specifies the scope of the Committee's responsibilities and procedures for carrying out such responsibilities. A copy of the Charter is available on the Company's website, www.innovative-ss.com under the heading Investor Relations. The Committee members are Messrs. Mittelstaedt (Chairman), Churchill and Bressner, each of whom is independent, as that term is defined in the applicable NASDAQ listing standards.

The Nominating/Corporate Governance Committee functions include establishing the criteria for selecting candidates for nomination to the Board, actively seeking candidates who meet those criteria and making recommendations to the Board of nominees to fill vacancies on, or as additions to, the Board and to monitor the Company's corporate governance structure.

The Committee seeks director candidates based upon a number of qualifications and criteria, including their independence, knowledge, judgment, character, leadership skills, education, experience, financial literacy, standing in the community and ability to foster a diversity of backgrounds and views and to complement the Board's existing strengths relative to the Company's business. In the case of potential independent director candidates, such eligibility criteria must be in accordance with SEC and NASDAQ rules. While the Nominating/Corporate Governance Committee does not have a formal policy with regard to the consideration of diversity in indentifying director nominees, the Nominating/Corporate Governance and the Board of Directors believe it is essential that the Board of Directors is able to draw on a wide variety of backgrounds and professional experience among its members. The Nominating/Corporate Governance Committee desires to maintain the Board of Directors' diversity through the consideration of factors such as education, skills and relevant professional experience. The Nominating/Corporate Governance Committee does not intend to nominate representational directors, but instead considers the entirety of each candidate's credentials in the context of these standards and the characteristics of the Board of Directors in its entirety.

The Committee conducts an annual assessment of the size and composition of the Board and Committees and reviews with the Board the appropriate skills and characteristics required of Board members. The Committee has not yet relied upon third-party search firms to identify board candidates, but reserves the right to do so as required. To date the Committee has relied upon recommendations from a wide variety of its business contacts, including current executive officers, directors, community leaders, and shareholders as a source for potential board candidates.

Neither the Nominating/Corporate Governance Committee nor the Company has engaged, or paid any fees to a search firm in connection with the nomination of the directors for election at the Annual Meeting covered by this Proxy Statement.

The Committee will consider nominees for election to the Board that are timely recommended by shareholders provided that a complete description of the nominees' qualifications, experience and background, together with a statement signed by each nominee in which he or she consents to act as such, accompany the recommendations. Such recommendations should be submitted in writing to the attention of Chairman, Nominating/Corporate Governance Committee, at the Company's address at 720 Pennsylvania Drive, Exton, PA, 19341, and should not include self-nominations. Section 3.10 of the Company's by-laws contains provisions setting forth the requirements applicable to a shareholder nomination for director. These requirements are summarized in this Proxy Statement under the caption "Shareholder Proposals for 2012 Annual Meeting And Other Matters."

Each of the current nominees for director listed under the caption "ELECTION OF DIRECTORS" is an existing director standing for re-election. In connection with the 2011 Annual Meeting, the Nominating/Corporate Governance Committee did not receive any recommendation for a candidate from any shareholder or group of shareholders owning more than 5% of the Company's common stock.

The Annual Meeting of Shareholders provides an opportunity each year for shareholders to ask questions of or otherwise communicate directly with members of the Company's Board of Directors on matters relevant to the Company. Each director is requested to attend in person the Annual Meeting. All six of the Company's then-serving directors attended the Company's 2010 Annual Meeting of Shareholders.

In addition, shareholders may communicate with the Board, or if applicable, to a specific individual director, by sending a written communication to the attention of the Board or such individual director at the following address: 720 Pennsylvania Drive, Exton, PA, 19341, (fax (610) 646-0150).

Copies of each written communication received at such address will be provided to the Board or to the specific individual director unless such communication is considered, in the reasonable judgment of the Corporate Secretary or other appropriate company officer, to be improper for submission to the intended recipient. Examples of shareholder communications that would be considered improper for submission include, without limitation, customer complaints, solicitations, communications that do not relate directly or indirectly to the Company or the Company's business or communications that relate to improper or irrelevant topics.

During the fiscal year ended September 30, 2010, the full Board held four meetings. From time to time during fiscal year 2010 the Board met in executive session without members of management present. The Audit Committee met eight times, the Investment Committee met one time, the Compensation Committee met four times and the Nominating/Corporate Governance Committees met four times. All directors attended at least 75% of the meetings of the full Board and the meetings of the committees on which they served.

In accordance with the Dodd-Frank Act, the Company is seeking the input of its shareholders on the frequency with which it will hold a non-binding advisory vote on the compensation of its named executive officers. In voting on this Item 2, shareholders may indicate their preference as to whether the advisory vote on the compensation of the Company's named executive officers should occur (a) once every three years, (b) once every two years or (c) once every year.

It is the opinion of the Board that the frequency of the shareholder vote on the compensation of the Company's named executive officers should be once every three years. The Company views the way it compensates its named executive officers as an essential part of its strategy to maximize the performance of the Company and deliver enhanced value to the Company's shareholders. The Board believes that a vote every three years will permit the Company to focus on developing compensation practices that are in the best long-term interests of its shareholders, while simultaneously giving shareholders the time frame they need to fully evaluate the design and effectiveness of those practices. The Board believes that a more frequent advisory vote could have the unintended consequence of causing the Company to focus on the short-term impact of its compensation practices to the possible detriment of the long-term performance of the Company.

The Board of Directors believes that an advisory vote on named executive officer compensation is the most effective way for shareholders to communicate with the Company about its compensation objectives, policies and practices, and it looks forward to receiving the input of the Company's shareholders on the frequency with which such a vote should be held. Although the results of this vote may impact how frequently the Company holds an advisory vote on executive compensation, this vote is not binding on the Company. The Board may decide, after considering the results of this vote, that it is in the best interests of the Company's shareholders to hold the advisory vote on executive compensation on a different schedule than the option approved by the Company's shareholders.

The Board of Directors recommends a vote "FOR" a frequency vote on say-on-pay of once every three years.

In accordance with the Dodd-Frank Act, the Company is providing its shareholders with the opportunity to cast an advisory vote on the compensation of its named executive officers, as disclosed in the Compensation Discussion and Analysis section and accompanying tables beginning on page 21 of this Proxy Statement. The Company believes that it is appropriate to seek the views of its shareholders on the design and effectiveness of the Company's executive compensation program.

The Company's goal for its executive compensation program is to attract and retain exceptional individuals as executive officers and to provide key executives with motivation to perform to the full extent of their abilities to maximize the performance of the Company and deliver enhanced value to the Company's shareholders. The Company believes that its executive compensation program achieves these goals. For a more detailed description of the Company's financial results for fiscal year 2010, please see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2010, filed on December 14, 2010.

RESOLVED, that the compensation paid to the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion is hereby APPROVED.

As an advisory vote, this proposal is not binding upon the Company. However, to the extent that a significant percentage of votes are cast against the compensation of the Company's named executive officers, the Company will determine whether any actions are necessary to address the concerns reflected in such votes.

The Board of Directors recommends a vote "FOR" the resolution regarding compensation of the Company's named executive officers.

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

(Item 4 on Proxy Card)

The Audit Committee has retained Deloitte & Touche, LLP as the independent registered public accounting firm to audit the Company's consolidated financial statements for the fiscal year ending September 30, 2011. Although action by the shareholders on this matter is not required, the Audit Committee and the Board of Directors believe it is appropriate to seek shareholder ratification of this selection in light of the role played by the independent registered public accounting firm in reporting on the Company's consolidated financial statements. Ratification requires the affirmative vote of a majority of eligible shares present at the Annual Meeting, in person or by proxy, and voting thereon. If this appointment is not ratified by the shareholders, the Audit Committee may reconsider its selection.

One or more representatives of Deloitte & Touche, LLP are expected to attend the Annual Meeting. They will have an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

Services provided by Deloitte & Touche, LLP in prior fiscal years have included an audit of the annual consolidated financial statements of the company, an audit of the effectiveness of internal controls over financial reporting as required by the Sarbanes-Oxley Act of 2002 and other services related to filings made with the SEC. The aggregate fees billed by Deloitte & Touche, LLP in connection with services rendered during the fiscal years ended September 30, 2010 and 2009 were:

Audit fees for fiscal years 2010 and 2009 were for professional services rendered for the audit of the Company's annual consolidated financial statements, auditing the effectiveness of the Company's internal controls over financial reporting, review of the interim consolidated financial statements included in quarterly reports and services that are normally provided by Deloitte & Touche, LLP in connection with statutory and regulatory filings or engagements.

No audit-related fees were paid to Deloitte & Touche, LLP during fiscal year 2010. Audit-related fees for fiscal year 2009 were $29,608 and were related to SEC Comment letter matters.

No tax-related fees were paid to Deloitte & Touche, LLP during fiscal year 2010 or fiscal year 2009.

No other fees were incurred in connection with services provided by Deloitte & Touche, LLP during fiscal years 2010 and 2009 other than as described above.

The Audit Committee's policy is to pre-approve the engagement of accountants to render all audit and tax-related services for the Company, as well as any changes to the terms of the engagement. The Audit Committee pre-approves all proposed non-audit related services to be provided by the Company's independent registered public accounting firm. The Audit Committee reviews the terms of the engagement, a description of the engagement, and a budget for the engagement. The request for services must be specific as to the particular services to be provided. Requests are aggregated and submitted to the Audit Committee in one of the following ways: requesting approval of services at a meeting of the Audit Committee, through a written consent or by a designated member of the Audit Committee. The Audit Committee approved all 2010 and 2009 fees paid to the independent registered public accounting firm.

Pursuant to the adoption of the revised Audit Committee Charter, the Board of Directors has adopted a policy which prohibits the Company from entering into non-audit related consulting agreements for financial information systems design and implementation, for certain other services considered to have an impact on independence and for all other services prohibited by the Sarbanes-Oxley Act of 2002 and new SEC regulations. The policy also contains procedures requiring Audit Committee pre-approval of all audit and permitted non-audit services provided by the Company's independent registered public accounting firm.

The Board of Directors recommends a vote "FOR" ratification of the appointment of Deloitte & Touche LLP as the Company's independent registered public accounting firm.

The following report of the Audit Committee will not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates this information by reference. The following report shall not otherwise be deemed filed under such Acts.

The Audit Committee assists the Board in its oversight of the financial reporting process. The Committee operates pursuant to a charter. As set forth in the charter, management of the Company is responsible for the preparation, presentation and integrity of its financial statements, accounting and financial reporting principles and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The Company's independent registered public accounting firm is responsible for auditing the Company's financial statements and expressing an opinion as to their conformity with generally accepted accounting principles in the United States of America and for reviewing the Company's unaudited interim financial statements. The Audit Committee reviews and reassesses the adequacy of the charter on an annual basis. It is not the Audit Committee's duty or responsibility to conduct auditing or accounting reviews or procedures. The Committee will however take the appropriate actions to set an overall corporate "standard" for quality financial reporting, sound business risk practices, and ethical behavior.

The Audit Committee makes recommendations to the Board with respect to the selection and compensation of the Company's independent registered public accounting firm, the scope of the annual audits, and the fees to be paid to the independent registered public accounting firm. In addition, the Committee monitors the performance and independence of the Company's independent registered public accounting firm and approves all services provided to the Company by the independent registered public accounting firm. The Committee consults with and reviews recommendations made by

the independent registered public accounting firm with respect to financial statements, financial records and financial controls of the Company. The Audit Committee meets with management periodically to consider the adequacy of the Company's internal controls and discusses with management the Company's disclosure controls and procedures.

The Board, in its business judgment, has determined that each of the three directors on the Audit Committee is independent as required by Rule 5605(c)(2)(A) of the listing standards of the NASDAQ Stock Market, LLC. In addition, the Board has determined that each member of the Audit Committee is financially literate and at least one of the Audit Committee members, Mr. Rau, is an audit committee financial expert as defined by SEC rules and regulations.

In the performance of its oversight function, the Audit Committee has reviewed and discussed the audited financial statements for the year ending September 30, 2010 with management of the Company and with the independent registered public accounting firm, who is responsible for expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States of America, its judgment as to the quality, not just the acceptability, of the Company's accounting principles, as well as an opinion on management's assessment of, and the effective operation of, the Company's internal control over financial reporting. The Audit Committee discussed with the Company's independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards No. 114, SEC Rule 2-07 and such other matters as are required to be discussed under auditing standards generally accepted in the United States of America. The Audit Committee received the written disclosures and the letter from the Company's independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence, including the compatibility of non-audit services with the independent registered public accounting firm's independence.

The Audit Committee discussed with the Company's independent registered public accounting firm the overall scope and plans for its 2010 audit and met with them, both with and without management present, to discuss the results of its examination, its evaluation of the Company's internal controls and the overall quality of the Company's financial reporting.

Based upon the review, reports and discussions described in this report, and subject to the limitations on the role and responsibilities of the Audit Committee referred to above and in the charter, the Audit Committee recommended to the Board of Directors that the audited financial statements for the year ending September 30, 2010 be included in the Company's Annual Report on Form 10-K for the year ended September 30, 2010 as filed with the Securities and Exchange Commission.

The Charter of the Audit Committee provides that it is the responsibility of the Audit Committee to review and approve any transaction between the Company and its officers, directors and 5% shareholders.

The Company's compensation program for non-employee directors consists of two elements of compensation: meeting fees and restricted stock awards. Each non-employee director is entitled to a fee of $1,000 for each Board meeting attended and $1,000 for each in-person committee meeting that is not held on the same day as a Board meeting. Historically, each non-employee director has also received an award of restricted stock pursuant to the Company's 2003 Restricted Stock Plan for non-employee directors, which was approved by shareholders at the Company's February 26, 2004 Annual Meeting of Shareholders. In 2010, the last of the shares remaining to be issued under the 2003 Restricted Stock Plan for non-employee directors were issued, and the balance of the awards to non-employee directors were made under the 2009 Plan. The Company intends to continue to grant annual awards of restricted stock to non-employee directors under the 2009 Plan.

Since fiscal year 2005, the Company has granted to each non-employee director an annual award of restricted stock with a value of $40,000 based on the closing price of the Company's stock on the first business day of the fiscal year. The Company's common stock closed at $4.86 per share on October 1, 2009 and accordingly, each non-employee director in the table below received a grant of 8,230 shares of restricted stock for fiscal year 2010, except for Mr. Mionis, who served from July 22, 2010. Mr. Mionis received shares valued at the closing price of the Company's stock on August 19, 2010 of $5.43. Each restricted stock award vests quarterly during the fiscal year provided the director continues to serve on the Board through each applicable vesting date. Mr. Ivan M. Marks served on the Board of Directors until April 21, 2010, at which time 50% of his award from October 1, 2009 had vested.

In addition, all directors are reimbursed for reasonable travel and lodging expenses actually incurred in connection with required attendance at Board meetings.

The Company maintains a Code of Ethics (the "Code of Ethics") applicable to its Directors, its principal executive officer and principal financial and accounting officer and persons performing similar functions. In addition, the Code of Ethics applies to all of the Company's employees, officers, agents and representatives. The Code of Ethics is posted on the Company's website, www.innovative-ss.com, under the heading Investor Relations.

Set forth below is a table identifying the Company's current executive officers who are not identified in the tables above. Biographical information for Mr. Hedrick is set forth above.

Roman G. Ptakowski. Mr. Ptakowski has been President since March 2003. Prior to that, Mr. Ptakowski served as a Group Vice President and General Manager at B/E Aerospace, Inc. Previously, Mr. Ptakowski was General Manager, Protective Relay Division of the ASEA Brown Bovari Power T&D Company, Inc. Mr. Ptakowski received a B.S. in Electrical Engineering from New York University and a MBA from Duke University.

Ronald C. Albrecht. Mr. Albrecht has been the Company's Chief Financial Officer since August 2010. Mr. Albrecht joined the Company following a twenty-seven year career with Smiths Aerospace, a U.K. based business, and later GE Aviation Systems (GEAS) following the GEAS purchase of Smiths Aerospace in 2007. He retired from GEAS in 2010. He has executive experience in both operational and financial roles. Recently, he has served as Vice President and General Manager of Smiths and later GEAS' Electro Mechanical Businesses. Prior to his operational roles, he served as Chief Financial Officer of Smiths Aerospace in London. In addition, he has substantial mergers and acquisition and strategic planning experience. Mr. Albrecht graduated from Dartmouth College with a B.A. in government and economics and from Stanford University with an M.B.A. in finance. He has a California CPA license (inactive).

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis section of the Company's proxy with management, and based on the Compensation Committee's review and discussion with management, the Compensation Committee recommended to the Company's Board of Directors that the Compensation Discussion and Analysis section be included in the Company's proxy statement for fiscal year 2010.

Overall, the compensation program is designed to reward the contributions of each individual executive officer to shareholder value and to provide sufficient incentives to executive officers to ensure their dedication to the Company. As discussed further below, the Company seeks to achieve these goals by providing sufficient base salaries to compensate executives for their day-to-day performance of their duties and awarding cash bonuses when the executive makes progress toward or attains the personal or corporate goals and objectives the Company. Also, from time to time, the Company grants equity-based awards when it believes that such equity awards will further align the interests of named executive officers with those of the Company's shareholders and provide an additional incentive to executive officers to contribute to the achievement of the Company's financial and strategic objectives.

Generally, upon hiring or promoting a named executive officer, the Compensation Committee sets base salary and other compensation on the basis of subjective factors, including experience, individual achievements, level of responsibility assumed at the Company and may also consider market compensation practices from time to time. Actual base salaries, cash bonuses, and equity-based awards for each named executive officer may be adjusted from year to year based upon each named executive officer's annual review and progress toward or attainment of personal and corporate goals and objectives, including Company financial performance, shareholder return and such other factors as the Compensation Committee deems appropriate and in the best interests of its shareholders.

Each named executive officer's annual review is a subjective process whereby the Chief Executive Officer or Compensation Committee evaluates such named executive officer's contributions toward the development and execution of strategic plans, leadership skills and motivation and involvement in industry groups. The weight given such factors by the Compensation Committee may vary from one named executive officer to another.

The Compensation Committee seeks recommendations from the Chief Executive Officer regarding changes to or increases in elements of compensation for named executive officers. In addition, the Chief Executive Officer is principally responsible for reviewing each other named executive officer's performance and making recommendations for the Company's compensation package for such officers for the following fiscal year. The Compensation Committee independently reviews the performance of the Company's Chief Executive Officer. The Compensation Committee reviews the recommendations of the Chief Executive Officer carefully in light of his proximity to the other executives and knowledge of their contributions to and goals for continuing achievement with the Company.

The Company's compensation program for named executive officers consists of the following elements of compensation, each described in greater depth below:

The Company pays base salaries to named executive officers because the Company believes salaries are essential to recruiting and retaining qualified executives. In addition, because base salaries are subject to increase based on each named executive officer's performance for the Company, base salaries also create an incentive for named executive officers to make meaningful contributions to the Company's success. Base salaries are initially set by the Compensation Committee upon hiring or promoting a named executive officer, and may be incorporated into employment contracts entered into with the Company's named executive officers. Base salary levels are initially set based on the named executive officer's previous experience and employment, as well as the named executive officer's expected duties and obligations to the Company. Thereafter, the Compensation Committee may increase a named executive officer's base salary each year based on the results of each named executive officer's annual review (conducted by the Chief Executive Officer for each of the other named executive officers and by the Compensation Committee for the Chief Executive Officer) and based on the Compensation Committee's subjective assessment of the Company's overall performance over the preceding year.

The Compensation Committee determined that, based on the Company's financial condition, there would be no increases in the base salaries of the named executive officers during fiscal year 2010. In addition, the Chief Executive Officer recommended to the Compensation Committee, and the Compensation Committee approved, a compensation package for Mr. Albrecht comparable to the compensation package previously received by Mr. Long, which included an annual base salary of $250,000.

From time to time the Company may award annual bonuses, in its discretion, to the named executive officers and may agree, in hiring or promoting a named executive officer, to a target bonus opportunity, expressed as a percentage of base salary, to be paid if the Company determines that the Company's financial performance goals or other objectives are attained.

Except as may be agreed when hiring a new executive officer, the Company has historically only awarded discretionary bonuses when the Company's financial performance has met or exceeded the Board's expectations. Because the Company's financial performance for fiscal year 2010 did not meet the Board's expectations, named executive officers did not receive discretionary bonuses in fiscal year 2010.

Because the Chief Executive Officer has historically determined whether and how much cash bonus to pay each named executive officer based on a discretionary review of Company financial performance, named executive officers' bonuses for prior fiscal years were not considered to be "performance based" under Section 162(m) of the Internal Revenue Code. Accordingly, the Company

would not have been entitled to deduct on its corporate tax return all of a named executive officer's base salary and bonus if the total amount of such base salary and bonus (and other compensation considered under Section 162(m) of the Code) exceeded $1,000,000 in that fiscal year. However, the Company has not paid any annual discretionary bonuses that have resulted in the Company's loss of deduction, nor does the Company anticipate paying such high bonuses to its named executive officers.

The Company awards equity-based compensation to named executive officers in order to provide a link between the long-term results achieved for its shareholders and the rewards provided to named executive officers, thereby ensuring that such officers have a continuing stake in the Company's long-term success. Equity-based compensation has historically been paid to named executive officers in the form of stock options. Such awards are made at the discretion of the Compensation Committee and are not timed or coordinated with the release of material, non-public information.

The Compensation Committee determined that, based on the Company's financial condition, no awards of equity compensation to named executive officers were appropriate in fiscal year 2010. Accordingly, the compensation expense shown in the "Option Awards" column of the Summary Compensation Table, below, reflects only the accounting expense associated with option grants made in years prior to fiscal year 2010.

In fiscal year 2010, the Company provided certain personal benefits to the Chief Executive Officer, as summarized below. The aggregate incremental cost to the Company of the perquisites received by Mr. Hedrick is included in the Summary Compensation Table, below.

Automobile. A Company car was available to the Chief Executive Officer for business and personal purposes during fiscal year 2010. The Company covers the costs of car insurance, upkeep and maintenance of the Company car. The Company believes that use of the Company's automobile represents a valuable perquisite for the Chief Executive Officer which is appropriate considering his value to the Company and that such benefit can be provided by the Company for relatively minimal cost.

Aircraft. The Company has, with the approval of the Independent Directors, permitted the Company's Chief Executive Officer to use the Company's corporate aircraft for personal travel. The Company believes that use of the Company's aircraft represents a valuable perquisite for the Chief Executive Officer which is appropriate considering his value to the Company and that such benefit can be provided by the Company for relatively minimal cost.

The following are standard benefits offered to all eligible Company employees, including named executive officers.

Retirement Benefits. The Company maintains a tax-qualified 401(k) savings plan for all eligible employees, including the named executive officers, known as the IS&S 401K Plan (the "Savings Plan"). The Savings Plan is a voluntary contributory plan under which employees may elect to defer compensation for federal income tax purposes under Section 401(k) of the Internal Revenue Code of 1986. The Company makes a matching contribution to the Savings Plan at one half of each participant's deferral rate limited to a maximum contribution of 2% of base salary and subject to limitations imposed by the IRS.

Medical, Dental, Life Insurance and Disability Coverage. Medical, dental, life insurance and disability coverage are available to all active eligible employees. The value of these benefits is not required to be included in the Summary Compensation Table because they are available to all eligible full-time employees.

Other Paid Time-Off Benefits. The Company provides vacation and other paid holidays to all employees, including the named executive officers.

In recognition of the need to attract executive leadership, the Company determined that it may be necessary to provide for severance benefits in the event of involuntary termination or termination in connection with a change in control for newly hired executives in the future. However, none of the current named executive officers is entitled to any severance or termination benefits.

Grants of Company stock options to named executive officers typically vest or become fully exercisable upon a change in control of the Company. The Company believes that such accelerated vesting is essential to maintaining the commitment and dedication of its key employees throughout a potential change in control.

The Company does not require its named executive officers to maintain a minimum ownership interest in the Company.

Section 162(m) of the Internal Revenue Code of 1986, as amended, generally denies a federal income tax deduction for certain compensation exceeding $1,000,000 paid to the Chief Executive Officer or any of the other named executive officers, excluding, among other things, certain performance-based compensation. Through September 30, 2010, this provision has not affected the Company's tax deductions. At the present time, the Compensation Committee believes that it is unlikely that the compensation paid to any of the Company's employees in a taxable year will exceed $1,000,000.

Shareholders wishing to submit proposals for inclusion in the proxy statement for the 2012 Annual Meeting of Shareholders must submit such proposals to the Company at 720 Pennsylvania Drive, Exton, PA 19341, Attention: Ronald C. Albrecht, on or before September 29, 2011. In order for the proposal to be included in the proxy statement, the shareholder submitting the proposal must meet certain eligibility standards and comply with the procedures established by the SEC as set forth in Rule 14a-8 of the Securities Exchange Act of 1934.

On May 21, 1998, the Securities and Exchange Commission adopted an amendment to Rule 14a-4, issued under the Securities Exchange Act of 1934. The amendment to Rule 14a-4(c)(1) governs a company's use of discretionary proxy voting authority for a shareholder proposal which the shareholder has not sought to include in the proxy statement. The amendment provides that if a proponent of a proposal fails to notify a company at least 45 days prior to the month and day of mailing of the prior year's proxy statement (or any date specified in an advance notice provision), then the management proxies will be allowed to use their discretionary voting authority when the proposal is raised at the meeting, without any discussion of the matter in the proxy statement. With respect to the Company's 2012 Annual Meeting of Shareholders, if the Company does not receive notice of a shareholder proposal, which the shareholder has not previously sought to include in the proxy statement, by December 13, 2011, the management proxies will be allowed to use their discretionary authority.

The Company's by-laws provide that a shareholder proposal (including a shareholder nomination of a director) must meet certain predetermined requirements in order to be considered at the Annual Meeting. In order to be considered, a shareholder's proposal must be made in writing and delivered to, or mailed and received at, the Company's principal executive offices not less than one hundred twenty (120) days nor more than one hundred fifty (150) days prior to the date that the Company's proxy statement was released to shareholders in connection with the previous year's annual meeting of shareholders in the case of an annual meeting that is called for a date that is within 30 days before or after the anniversary date of the immediately preceding annual meeting of shareholders. However, in the case of an annual meeting that is called for a date that is not within 30 days before or after the anniversary date of the immediately preceding annual meeting, proposals must be received not later than the close of business on the tenth (10th) day following the day on which notice of the date of the

meeting was mailed or public disclosure of the date of the meeting was made, whichever occurs first. The notice to the Secretary must set forth certain information as specified in the Company's by-laws.

As of the date of this proxy statement, the Board knows of no other business which may properly be and is likely to be brought before the annual meeting. If a shareholder proposal that was excluded from this proxy statement in accordance with Rule 14a-8 of the Securities Act or the Company's by-laws is properly brought before the annual meeting, it is intended that the proxy holders will use their discretionary authority to vote the proxies against said proposal. If any other matters should arise at the annual meeting, shares represented by proxies will be voted at the discretion of the proxy holders.
