PROXY STATEMENT FOR THE 2010 ANNUAL MEETING OF STOCKHOLDERS

Our 2010 Annual Meeting of Stockholders will be held on Wednesday, October 13, 2010, at 9:00 a.m. (Chicago time), at AAR CORP.'s corporate headquarters located at One AAR Place, 1100 North Wood Dale Road, Wood Dale, Illinois 60191. We invite you to attend the Annual Meeting and ask that you vote on the items described in this Proxy Statement.

I. VOTING INFORMATION

This Proxy Statement and the related proxy materials are first being provided to stockholders on or about September 1, 2010 in connection with the solicitation of proxies by the Board of Directors for use at the 2010 Annual Meeting of Stockholders.

This year we are again providing access to our proxy materials over the Internet under the Securities and Exchange Commission's "notice and access" rules. To that end, we mailed to our stockholders a "Notice of Internet Availability of Proxy Materials," which provides instructions on how to:

What matters are stockholders voting on at this Annual Meeting?

Stockholders are voting on three matters:

The Board of Directors unanimously recommends that stockholders vote "FOR" each of these matters.

Who is entitled to vote?

The Board of Directors fixed August 19, 2010 as the record date for determining who is entitled to vote at the Annual Meeting.

If you were a stockholder of record (i.e., you held your shares in your own name rather than through a broker, bank or other nominee) at the close of business on August 19, 2010, you may vote your shares at the 2010 Annual Meeting.

If you were a street-name stockholder (i.e., you held your shares through a broker, bank or other nominee) on the record date, you are considered a "beneficial owner" of the stock. To vote those

ZEQ.=1,SEQ=5,EFW="2199972",CP="AAR CORP",DN="1",CHK=432763,FOLIO='blank',FILE='DISK131:[10ZBY1.10ZBY74501]DA74501A.;11',USER='EYOUNG',CD='27-AUG-2010;10:33'

Table of Contents

shares at the Annual Meeting, you must give voting instructions to your broker, bank or other intermediary who is the "nominee holder" of your shares. Effective January 1, 2010, your broker is no longer permitted to vote on your behalf in the election of directors unless you provide specific voting instructions to your broker. The Company has directed brokers, banks and other nominee holders to obtain voting instructions from their beneficial owners. Proxies submitted by nominee holders on behalf of beneficial owners will count toward a quorum and will be voted as instructed by the beneficial owners. You will receive additional instructions from your broker, bank or other nominee explaining how you may vote your shares held in street name.

A list of record stockholders entitled to vote will be available at the Company's offices, One AAR Place, 1100 North Wood Dale Road, Wood Dale, Illinois 60191 for 10 days prior to the meeting and at the meeting location during the meeting.

On the August 19, 2010 record date, 39,264,712 shares of common stock of the Company ("Common Stock") were outstanding. You will have one vote on each matter to be voted on for each share of Common Stock you owned on the record date.

How do stockholders vote by proxy or in person?

Stockholders of record at the close of business on the record date may vote on the matters that are before the Annual Meeting by proxy by completing, signing, dating and returning the enclosed proxy card, by voting by telephone or over the Internet, or by attending the Annual Meeting and voting in person.

How do stockholders vote by telephone or over the Internet?

You are encouraged to vote either by telephone or over the Internet. This will eliminate the need to sign, date and return your proxy card. You can vote by telephone or over the Internet 24 hours a day, seven days a week, until 10:59 p.m. (Chicago time) on the day prior to the Annual Meeting. Specific instructions for using the telephone and Internet voting methods are set forth on the proxy card. If you vote by telephone or over the Internet, please do not return your proxy card.

How do stockholders revoke a proxy?

You may revoke your proxy at any time before it is exercised, but only by:

How will the proxy holders vote shares?

The proxy holders will vote shares in accordance with instructions on the proxy card. If no instructions are specified, the shares will be voted FOR the election of the nominees for Class II director designated by the Board; FOR the approval of the AAR CORP. Section 162(m) Annual Cash Incentive Plan; FOR the ratification of the appointment of KPMG LLP as the Company's independent registered public accounting firm, and upon any other matter that may properly come before the Annual Meeting in the discretion and best judgment of the proxy holders. If any

Table of Contents

director nominee becomes unavailable for election for any reason prior to the Annual Meeting vote, the Board may reduce the number of directors to be elected or substitute another person as nominee, in which case the proxy holders will vote for the substitute nominee.

How will the votes be counted?

All votes cast in person or by proxy will be tabulated by the inspectors of election appointed for the Annual Meeting. A majority of the outstanding shares of Common Stock entitled to vote, present in person or represented by proxy at the Annual Meeting, will constitute a quorum.

The inspectors of election will treat directions to withhold authority, abstentions and broker non-votes (i.e., where a nominee holding shares for a beneficial owner has not received voting instructions from the beneficial owner with respect to a particular matter and such nominee does not possess or choose to exercise his discretionary authority with respect to such matter) as shares that are present for purposes of determining a quorum. Directions to withhold authority will have no effect on the election of directors because directors are elected by a plurality of votes cast. Abstentions and broker non-votes will be disregarded for purposes of determining whether a matter has been approved because they are not considered votes cast. It is not anticipated that there will be any broker non-votes on the ratification of the appointment of KPMG LLP since brokers will have discretion to vote on this proposal even if they do not receive voting instructions from their beneficial owners.

Who is the Company's proxy solicitor?

The Company has engaged D. F. King & Co., 48 Wall Street, New York, New York 10005, to assist the Company in soliciting proxies at a total estimated cost of $11,500, plus reasonable out-of-pocket expenses. The cost of soliciting proxies will be paid by the Company. D. F. King & Co. may solicit proxies by mail, telephone, facsimile, e-mail, or in person. Certain officers, directors and employees of the Company may also solicit proxies for no additional compensation.

II. PROPOSAL 1 — ELECTION OF DIRECTORS

The Restated Certificate of Incorporation and By-Laws of the Company provide that the Board of Directors shall consist of between three and 15 directors, with the exact number of directors to be set from time to time by the Board. The number of directors is currently set at 11. The members of the Board are divided into three classes, each having a three-year term that expires in successive years: Class I (three directors), Class II (four directors), and Class III (four directors).

The Board of Directors has nominated three directors to be elected in Class II at the Annual Meeting, each to serve a three-year term expiring at the 2013 Annual Meeting or until the individual is succeeded by another qualified director who has been duly elected. The nominees for director in Class II at the Annual Meeting are Norman R. Bobins, James E. Goodwin and Marc J. Walfish. Gerald F. Fitzgerald, Jr., a director of the Company since 2006, has elected not to stand for re-election, and, effective as of October 13, 2010, the Board reduced the number of directors to 10, with Class I consisting of three directors, Class II consisting of three directors, and Class III consisting of four directors.

Each nominee is currently serving as a director of the Company. Each nominee has been determined by the Board to be "independent" within the meaning of the New York Stock Exchange ("NYSE") rules. Under Delaware law and the Company's By-Laws, the three nominees for director who individually receive the greatest number of votes will be elected directors of the Company.

The Board of Directors recommends that stockholders vote "FOR" all nominees.

IV. CORPORATE GOVERNANCE

General

The Company has an ongoing commitment to good governance and business practices. We regularly review our policies and procedures, giving due consideration to current developments and "best practices" in the area of corporate governance. We believe that we comply with all applicable Securities and Exchange Commission ("SEC") and NYSE rules and regulations and have adopted additional corporate governance practices that we believe are in the best interests of the Company and its stockholders.

Copies of the following corporate governance documents are available on the Company's website at www.aarcorp.com under "Investor Relations/Corporate Governance":

All of these corporate governance documents are also available in print to any stockholder upon written request to the Secretary of the Company at the Company's address listed on the first page of this Proxy Statement.

The Company maintains an Ethics Assist Line through a third-party provider to receive confidential complaints, information, suggestions or recommendations concerning the Company, its officers, directors and employees, policies, procedures, employment and business practices, accounting or audit matters, financial reporting or compliance with other Company policies or applicable regulatory or legal requirements. The Ethics Assist Line is toll-free and permits callers to identify themselves or remain anonymous at their election.

Director Independence

A majority of the members of the Board of Directors must be independent directors under the criteria established by the Board and under applicable NYSE rules. The Nominating and Governance Committee and the Board of Directors review each director annually and make a determination concerning independence after consideration of all known facts and circumstances. The Board has established categorical standards to assist it in determining director independence. The Company's "Categorical Standards and Policy for Determining Director Independence" include all of the elements of the applicable SEC and NYSE rules with respect to director independence, as well as those of the Company, and are attached as Appendix A to this Proxy Statement. Based on these categorical standards, its review of all relevant facts and information available, and the recommendations of the Nominating and Governance Committee, the Board, at its meeting in July 2010, affirmatively determined that no director has a material relationship with the Company that would impair the director's ability to exercise independent judgment and, accordingly, that each director is an independent director, except for David P. Storch, due to his status as Chairman of the Board and Chief Executive

Officer of the Company, and Timothy J. Romenesko, due to his status as President and Chief Operating Officer of the Company. Under the NYSE rules, a director employed by the Company is not an independent director by definition.

Board Leadership Structure

The Board of Directors determines the leadership structure for the Board and the Company in a manner that it believes best serves the interests of the Company's stockholders. As stated in the Company's Corporate Governance Guidelines, the Board has no fixed policy with respect to combining or separating the offices of Chairman of the Board and Chief Executive Officer. Currently, the Company's Chief Executive Officer, David P. Storch, is also Chairman of the Board. The Board believes this structure is the most effective and appropriate leadership structure for the Board and the Company at this time for the following principal reasons:

Risk Management Oversight

The Board of Directors, directly and through its committees, is responsible for overseeing management's process for assessing and managing the Company's exposure to risks. In that role, the Board regularly reviews and responds to management's business strategies and initiatives, the Company's quarterly and annual financial results and information relating to the Company's competitive position, customer base, and capital and liquidity position. The Audit Committee oversees management's enterprise risk committee, which is responsible for identifying the principal risks to the Company, developing and implementing risk mitigation strategies and reporting to the Audit Committee. In the fiscal year ending May 31, 2010 ("Fiscal 2010"), the enterprise risk committee reviewed and discussed with the Audit Committee the Company's principal risks and outlined its risk mitigation approach for addressing these risks. The Audit Committee reviews and reports to the Board on risks relating to accounting, financial reporting and legal compliance, risks identified by the Company's internal and external auditors, and matters raised through the Company's Ethics Assist Line. The Compensation Committee oversees and reports to the Board on the Company's incentive compensation programs to assure that they are appropriately structured to incentivize officers and key employees while assuring appropriate risk. The Nominating and Governance Committee oversees and reports to the Board

on corporate governance risks, including director independence and related party transactions. The Board and its committees receive information from and have regular access to the individual members of management responsible for managing risk, including the Company's Chief Executive Officer, President, Chief Financial Officer, Group Vice Presidents, Controller, General Counsel and Internal Auditor.

Communications with the Board of Directors

Stockholders and other interested parties may communicate with the Board, the Chairman of the Board, independent directors as a group, or any individual director or Committee Chairman by mail addressed to: AAR CORP., Attention: Independent Directors, or the name of the individual director, c/o Corporate Secretary, AAR CORP., One AAR Place, 1100 North Wood Dale Road, Wood Dale, Illinois 60191. The independent members of the Board of Directors have approved procedures for the processing, review and disposition of all communications sent by stockholders or other interested parties to the Board of Directors.

Corporate Governance Guidelines

The Company adopted Corporate Governance Guidelines to codify long-standing policies and procedures and to demonstrate its commitment to corporate governance best practices. These Guidelines, under the administration of the Nominating and Governance Committee of the Board of Directors, address director qualification standards, director responsibilities, director access to management and independent advisors, director compensation, management evaluation and succession, and the annual performance evaluation of the Board of Directors. These Guidelines are reviewed annually by the Nominating and Governance Committee and the Board of Directors.

Director Nominations and Qualifications

The Board of Directors, acting through the Nominating and Governance Committee, is responsible for identifying, evaluating and recommending candidates for director. The Nominating and Governance Committee obtains recommendations from management, other directors, business and community leaders, and stockholders, and may retain the services of a consultant to assist in identifying candidates. The Nominating and Governance Committee considers all director candidates in the same manner, including director candidates recommended by stockholders, regardless of the source of the recommendation. In its evaluation of director candidates, the Nominating and Governance Committee considers the factors specified in the Company's Corporate Governance Guidelines, including:

Table of Contents

In addition, while the Board of Directors does not have a formal diversity policy relating to director nominations, the Nominating and Governance Committee considers the racial, ethnic and gender diversity of the Board and director candidates, as well as the diversity of their knowledge, skills, experience, background and perspective, to assure that the Company maintains the benefit of a diverse, balanced and effective Board.

A full list of the qualifications of director candidates considered by the Committee is set forth in the Corporate Governance Guidelines on the Company's website at www.aarcorp.com under "Investor Relations/Corporate Governance" and is available in print to any stockholder upon written request to the Secretary of the Company at the address listed on the first page of this Proxy Statement. The Nominating and Governance Committee regularly reviews these qualifications and the performance of individual directors and the Board as a whole.

Following its evaluation of director candidates, the Nominating and Governance Committee recommends its director nominees to the Board of Directors. The Board makes the final determination of director nominees to be elected by the Company's stockholders based on its review and consideration of the Committee's recommendation.

Stockholders may submit a proposed nomination to the Nominating and Governance Committee for consideration with respect to the Annual Meeting of Stockholders for the year 2011 by writing to the Secretary, AAR CORP., One AAR Place, 1100 North Wood Dale Road, Wood Dale, Illinois 60191. To be considered, proposed nominations must be received by the Secretary of the Company no later than April 18, 2011, must state the reasons for the proposed nomination and contain the information required under the Company's By-Laws, including the full name and address of each proposed nominee, as well as a brief biographical history setting forth past and present directorships, employment and occupations, information as to stock ownership, other arrangements regarding the Common Stock, and any other qualifications. Proposed nominations must also include a statement indicating that the proposed nominees have consented to being named in the Proxy Statement and to serve if elected.

Executive Sessions

Independent directors of the Board meet in executive session without management as part of each regular Board meeting and otherwise when circumstances make it advisable or necessary. The Chairman of the Nominating and Governance Committee presides at the executive sessions of independent directors.

Code of Business Ethics and Conduct

The Company's Code of Business Ethics and Conduct adopted by the Board of Directors applies to all directors, officers, and employees, including the Chairman and Chief Executive Officer, the President and Chief Operating Officer, the Chief Financial Officer, and the Chief Accounting Officer and Controller. The purpose of the Code of Business Ethics and Conduct is to promote the highest ethical standards in the Company's business practices and procedures, including the

We will post any amendments to the Code of Business Ethics and Conduct and any waivers from the Code granted by the Board to directors or executive officers on the Company's website as required under SEC rules.

Related Person Transaction Policy

The purpose of the Related Person Transaction Policy adopted by the Board of Directors is to provide for the identification, review, and consideration of transactions between the Company or its subsidiaries and any related persons. "Related persons" means the Company's directors, director nominees, executive officers, greater than five percent beneficial owners of the Company's voting securities, members of their immediate families, and any firm, corporation or other entity in which any of the foregoing persons is employed or is a partner or principal or in a similar position or in which such person has a 10% or greater beneficial ownership interest.

Under the Policy, any related person transaction involving amounts in excess of $120,000, subject to certain exceptions, must be reviewed, considered, and approved by the Board of Directors directly or through the Nominating and Governance Committee. Review of a proposed related person transaction takes into consideration, among other factors deemed appropriate, the purpose of, and the potential benefits to the Company of, the related person transaction, and the impact of the related person transaction on a director's independence in the event that the related person is a director or an immediate family member of a director. No member of the Board or the Nominating and Governance Committee may participate in any review, consideration, or approval of any related person transaction with respect to which such member or any of his or her immediate family members is the related person.

The Policy provides that the Company may undertake certain pre-approved related person transactions without further specific review, consideration, and approval, including the following:

The Executive Committee held one meeting during Fiscal 2010.

Board Meetings and Attendance

During Fiscal 2010, the Board held eight meetings. All persons who were directors during Fiscal 2010 attended at least 75% of the Board meetings and meetings of Board committees on which they served. The Company's Corporate Governance Guidelines provide that directors are expected to attend all stockholder meetings. All the members of the Company's Board of Directors attended the Company's 2009 Annual Meeting of Stockholders.

Director Compensation

The Board believes that compensation for any director who is not an officer or employee of the Company or any subsidiary ("Non-Employee Director") should be a mix of cash and equity compensation. Director compensation and benefits are recommended to the Board of Directors from time to time by the Compensation Committee for Board approval. Directors who are officers or employees of the Company or any subsidiary receive no additional compensation for service on the Board or any of its committees.

Cash Compensation

Each Non-Employee Director receives an annual retainer of $45,000, a fee of $2,500 for attendance at each meeting of the Board or any Board committee attended in person ($1,250 per meeting for telephonic Board or Board committee meetings), plus reimbursement of expenses. Each Committee Chairman (other than Mr. Storch) receives an additional $5,000 annual retainer.

Annual retainer fees are paid quarterly, Committee Chairman retainer fees are paid annually, and meeting fees are paid promptly following each meeting attended, as are expense reimbursements. Each Non-Employee Director may elect to defer receipt of the retainer and meeting fees pursuant to the Company's Non-Employee Directors' Deferred Compensation Plan. Under the Plan, deferred retainer fees are converted into stock units equivalent to shares of Common Stock, and deferred meeting fees are credited with interest quarterly based on the 10-year United States Treasury Bond rate. Distributions of deferred retainer fees under the Plan are made in cash or equivalent value Common Stock, at the participant's election, and distribution of deferred meeting fees are made in cash, in each case upon termination of service on the Board or on the happening of certain other events, as specified in the Plan.

Equity Compensation

Each Non-Employee Director also is eligible to receive stock option grants and restricted stock awards from time to time under the AAR CORP. Stock Benefit Plan, as may be determined by the Compensation Committee and the Board of Directors. On July 14, 2009, the Board of Directors, upon the recommendation of the Compensation Committee, approved a restricted stock grant to each Non-Employee Director of 4,000 shares for Fiscal 2010, vesting pro-rata over a three-year period on each anniversary of the grant date. On that same date, the Board of Directors approved a restricted stock grant to each Non-Employee Director of 4,000 shares to be made for the fiscal year ending May 31, 2011 ("Fiscal 2011"), also with a three-year vesting period. Restricted stock recipients are entitled to vote and receive dividends, if any, on shares of restricted stock.

Other Compensation

Each Non-Employee Director, upon being elected a director, receives term life insurance coverage of $200,000 and is eligible (with spouse) to participate in a Company-paid, annual physical program. The Company also reimburses its directors for travel, lodging and related expenses they incur in attending Board and committee meetings.

Role of the Compensation Committee

The Compensation Committee is responsible for structuring and administering executive compensation. The Compensation Committee is comprised of five individuals, each of whom has been determined by the Board of Directors to be:

The Compensation Committee relies upon the judgment of its members and considers historical and comparative compensation information and other relevant information provided by management and outside compensation consultants in making compensation decisions. It reviews the performance of the Company and the executives during the year, taking into account established goals, leadership qualities, operational performance, business responsibilities, career experience, and long-term potential to enhance stockholder value. In addition, the Compensation Committee considers other key factors that it deems relevant in making executive compensation decisions, including those identified below.

Key Factors Affecting Executive Compensation Decisions

The following are key factors affecting the executive compensation decisions made by the Compensation Committee for the Company's executives, including its named executive officers:

Principal Compensation Elements of the Executive Compensation Program

Base Salary

The Company provides competitive base salaries designed to reward individual performance and contributions consistent with an executive officer's position and responsibilities. The Compensation Committee annually reviews the base salaries of all corporate officers, including the Chief Executive Officer and the other named executive officers, and may adjust base salaries depending upon:

26

ZEQ.=4,SEQ=30,EFW="2199972",CP="AAR CORP",DN="1",CHK=733667,FOLIO='26',FILE='DISK131:[10ZBY1.10ZBY74501]DE74501A.;64',USER='CGONCE',CD='27-AUG-2010;11:49'

Table of Contents

The Compensation Committee sets the base salaries of the Company's named executive officers in the 50 th to 75 th percentile of salary levels of comparable positions in its peer group companies. The Company does not target base salaries as any specific percentage of total compensation when setting base salary; however, given the emphasis on the link between pay and performance, base salaries are a less significant percentage of total compensation compared to the Company's variable performance-based compensation.

In July 2009, management recommended, and the Compensation Committee approved, the freezing for the first six months of Fiscal 2010 the base salaries of all employees, including the named executive officers, who earned more than $100,000 (employees earning $75,000 or less received a 2% salary increase and employees earning between $75,000 and $100,001 received a 1% salary increase). The one exception was Mr. Poulton, whose base salary was adjusted to $360,000 from $330,000 to put him at the 50th percentile of base salary levels among chief financial officers of the Company's new peer group. The salary freeze reflected management's concern with the state of the recovery of the commercial aviation industry and was to be revisited by management in mid-Fiscal 2010. In December 2009, management determined that all employees not previously awarded a 2% salary increase, including the named executive officers, would receive an increase up to that level for the balance of Fiscal 2010.

For Fiscal 2011, the Company instituted a Company-wide 2% merit pool increase for Fiscal 2011 base salaries, effective June 1, 2010. Mr. Storch's base salary was set at $850,000 under his amended and restated employment agreement effective May 31, 2010, as approved by the Compensation Committee.

Annual Cash Incentive Opportunities

The Compensation Committee believes that annual incentive opportunities, payable in cash, serve as an appropriate incentive for achievement of the Company's short-term performance goals. Within the first 90 days of each fiscal year, the Company establishes specific performance goals for its executive officers, including the named executive officers, that govern the payment of annual cash incentive awards for that fiscal year. The Company pays an annual cash incentive award to each named executive officer, measured as a percentage of the executive officer's salary (except for Messrs. Clark and Stinson), based on the extent to which the Company and the executive officer achieve applicable performance goals. Generally, performance at a target level will result in a target annual cash incentive award, and performance above or below target will result in payment of an annual cash incentive award at a higher or lower percentage of salary, respectively. Performance below a minimum threshold will result in no annual cash incentive award. Messrs. Clark and Stinson's annual cash incentive awards are based on the performance results for their business groups (Aviation Supply Chain in Mr. Clark's case and Structures and

Systems in Mr. Stinson's case), as described below. In all cases, the Company reserves the right to reduce the amount of any annual cash incentive award payable to an executive based on individual performance and to reflect the inclusion or exclusion of extraordinary items in the determination of the award.

Fiscal 2010 Performance Goals. In July 2009, the Compensation Committee approved Fiscal 2010 performance goals for annual cash incentive opportunities for Messrs. Storch, Romenesko and Poulton based on the Company's net income (target of $67.4 million) and a leverage ratio (target of 50% or less). For purposes of measuring attainment of these performance goals for Fiscal 2010, net income was the Company's net income reported in its audited financial statements, subject to adjustment for one-time losses, special charges or other extraordinary items, and except that the net income performance goal did not give effect to accounting changes relating to the Company's convertible notes as those changes became effective after the Compensation Committee set the net income performance goal, and leverage ratio was based on a long-term recourse net debt to capital ratio. The choice of these performance measures reflected the emphasis placed by the Company on preserving and growing stockholder wealth and maintaining a strong balance sheet.

For Fiscal 2010, the performance goals for Messrs. Clark and Stinson's annual cash incentive opportunities were based on the following financial measures for their respective business groups (Aviation Supply Chain for Mr. Clark and Structures and Systems for Mr. Stinson) rather than overall Company performance: (i) pre-tax income (Mr. Clark: target of $27.6 million; Mr. Stinson: target of $33.6 million); (ii) return on invested capital (Mr. Clark: target of 16.1%; Mr. Stinson: target of 19.7%); and (iii) cash flow (Mr. Clark: target of $100 million; Mr. Stinson: target of $20 million). The choice of these performance goals for Messrs. Clark and Stinson likewise reflected the Company's emphasis on cash generation and preservation, as well as the Compensation Committee's belief that achievement of the performance goal targets would require superior performance by the Aviation Supply Chain and Structures and Systems business groups.

The relative weight assigned to each of these performance goals in Fiscal 2010 for each named executive officer is set forth in the table below:

1 An annual cash incentive award at the threshold level requires attainment of 70% in Mr. Poulton's case and 80% in the case of Messrs. Storch and Romenesko of the performance goal targets specified above. An annual cash incentive award at the target level requires attainment of 100% of the performance goal targets, and an annual cash incentive award at the maximum level requires attainment of 120% of such performance goal targets. 2 Mr. Clark's and Mr. Stinson's Fiscal 2010 annual cash incentive award opportunities were based upon the results of their respective business group as measured by pre-tax income, cash flow and return on invested capital. Mr. Clark's Fiscal 2010 target annual cash incentive award opportunities were $300,000 based on pre-tax income, $130,000 based on cash flow and $50,000 based on return on invested capital, for a total target annual cash incentive award opportunity of $480,000 (which, for comparison purposes, equated to 147% of his Fiscal 2010 base salary). Mr. Stinson's Fiscal 2010 target annual cash incentive award opportunities were $300,000 based on pre-tax income, $100,000 based on cash flow and $65,000 based on return on invested capital, for a total target annual cash incentive award opportunity of $465,000 (which, for comparison purposes, equated to 140% of his Fiscal 2010 base salary). For each of Messrs. Clark and Stinson, the annual cash incentive award opportunities based on the cash flow and return on invested capital performance goals are either earned in full or not at all depending upon whether their respective business group achieves the designated performance goal targets. As to the pre-tax income performance goal, (i) no annual cash incentive award is payable unless the respective business group achieves the pre-tax income performance goal target at an 80% level (in which case Messrs. Clark and Stinson are each entitled to a $240,000 annual cash incentive award); achievement of the pre-tax income performance goal target at a 100% level results in a target annual cash incentive award of $300,000; and achievement between 80% and 100% results in a pro-rata annual cash incentive award between $240,000 and $300,000; and (ii) Messrs. Clark and Stinson are each entitled to 1% of any pre-tax income in excess of their respective business group's Fiscal 2010 pre-tax income performance goal target.

Fiscal 2010 Actual Results. The Company achieved 81.3% of its Fiscal 2010 net income performance goal target, with net income of $54.8 million, and fully achieved its long-term recourse net debt to capital performance goal target, with a ratio of 29.1% (in each case determined after giving effect to the previously described adjustments), resulting in annual cash incentive awards at or around the target level for Messrs. Storch, Romenesko and Poulton. Structures and Systems exceeded its pre-tax income performance goal target and achieved its return on invested capital and cash flow performance goal targets for Fiscal 2010, resulting in an above-target annual cash incentive award for Mr. Stinson. The continuing economic recession

and its impact on the commercial aviation industry caused Aviation Supply Chain to fall short of its performance goal targets for Fiscal 2010, resulting in no annual cash incentive award for Mr. Clark under the short-term incentive plan. On management's recommendation, however, the Compensation Committee approved a discretionary bonus to Mr. Clark for Fiscal 2010 performance, as set forth under the "Bonus" column of the Summary Compensation Table, based upon his contributions to the Company. The annual cash incentive awards that were paid to the other named executive officers for Fiscal 2010 performance are set forth under the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table.

Fiscal 2011 Short-Term Incentive Plan. At its July 13, 2010 meeting, the Compensation Committee approved the Company's Fiscal 2011 Short-Term Incentive Plan. This Plan sets performance goals based on net income and a leverage ratio (average total recourse net debt to capital) for purposes of the Company's Fiscal 2011 annual cash incentive opportunities for certain senior executives, including the named executive officers other than Mr. Stinson. As a result of his appointment as Vice President, Commercial Strategy and Business Development effective June 1, 2010, Mr. Clark's Fiscal 2011 annual cash incentive opportunity will be based on the Company's performance goals. The Plan does not cover Mr. Stinson, for whom performance goals were set based on the pre-tax income, return on invested capital and cash flow of the Structures and Systems business group.

Long-Term Incentive Opportunities

The Company uses equity compensation to provide long-term incentive opportunities for its named executive officers and certain other officers and key employees. The Company believes that the use of equity compensation rewards executives in a manner that aligns their interests with the interests of the Company's stockholders. Long-term equity-based compensation represents the most significant component of total compensation for the Company's executives.

Equity compensation is provided under the stockholder-approved AAR CORP. Stock Benefit Plan ("Stock Benefit Plan"). Under the Stock Benefit Plan, the Compensation Committee has the discretion to grant stock options, performance-based restricted stock awards, employment or time-based restricted stock awards, or any combination of the foregoing. The Stock Benefit Plan also provides for the use of stock appreciation units; however, to date, the Compensation Committee has not granted any stock appreciation units.

Generally, when determining restricted stock and stock option grant opportunities, the Compensation Committee considers the executive's position and responsibilities in the Company, performance and contributions during the preceding year, capabilities and potential for future contributions to the Company, the number of restricted stock shares and options previously granted to the executive and, for senior management (including the named executive officers), their stock ownership relative to the Company's stock ownership guidelines and the Chief Executive Officer's recommendation.

Fiscal 2010 Long-Term Incentive Plan. In Fiscal 2010, the Company's long-term incentive plan consisted of (i) performance-based restricted stock approved by the Compensation Committee as part of the Fiscal 2009 and 2010 performance-based restricted stock program and (ii) stock options.

Fiscal 2011 Long-Term Incentive Plan. The Compensation Committee, based on its consideration of current executive pay trends and practices and the business goals and strategies of the Company, approved the Fiscal 2011 long-term incentive plan at its meeting on July 12, 2010. This new plan provides for the grant of stock options, time-based restricted stock and performance-based restricted stock in lieu of relying solely on performance-based restricted stock, as was the practice in recent years. In addition, the performance-based restricted stock has a single three fiscal year performance period (Fiscal 2011 through Fiscal 2013) and a single performance goal (cumulative net income over the three fiscal year performance period), in contrast to recent programs which had three separate performance periods over a two-year program period and two performance goals (net income and a leverage ratio). The Fiscal 2011 long-term incentive plan, like the prior programs, includes a stock price acceleration provision.

Retirement Benefits

The Company's named executive officers participate in three retirement plans: the Retirement Plan, the Retirement Savings Plan and the Supplemental Key Employee Retirement Plan (the "SKERP").

• Retirement Plan: Benefit accruals under the tax-qualified Retirement Plan ceased on June 1, 2005 for most employees, including Messrs. Storch, Romenesko and Clark, the only named executive officers who participate in the Retirement Plan. At termination of employment, a participant is eligible to receive the amount credited to his account under the Retirement Plan, which consists of (i) an opening balance for those participants who participated in the Retirement Plan at December 31, 1999 equal to the then present value of the benefit accrued as of such date, (ii) quarterly pay credits (through May 31, 2005) based on the participant's age and service, and (iii) quarterly interest credits until the account is distributed based on the 30-year Treasury securities rate.

• Retirement Savings Plan: The Retirement Savings Plan is a tax-qualified 401(k) plan that covers most U.S. employees. An employee can elect to defer up to 75% of his compensation on a pre-tax basis, up to a maximum of $16,500 in 2010, or $22,000 if age 50 or over. Unless an employee elects otherwise, (i) participation for non-union employees hired on or after June 1, 2007 and prior to June 26, 2009 is automatic at a 3% deferral rate and (ii) participation for non-union employees hired on or after June 26, 2009 is automatic at a 5% deferral rate, with automatic 1% annual increases. The Company provides a matching contribution equal to 20% of the participant's deferrals (up to 5% of compensation), a profit sharing contribution of up to 4% of compensation based on the participant's deferrals and the performance of the participant's operating unit, and a retirement benefit contribution of up to 4% of compensation based on the participant's age and service. • SKERP: The SKERP is a non-qualified retirement plan that contains a defined benefit portion and a defined contribution portion. Benefit accruals under the defined benefit portion for all employees other than Messrs. Storch and Romenesko ceased as of October 1, 2001 and were distributed to the participants. The benefits accrued under the defined benefit portion as of May 31, 2006 for Messrs. Storch and Romenesko were converted to a lump sum and transferred to the defined contribution portion of the SKERP. The defined contribution portion of the SKERP is intended to provide eligible employees with the portion of their elective deferrals and the Company's matching and profit sharing contributions that could not be made under the Retirement Savings Plan due to Internal Revenue Code limitations on the amount of compensation that can be taken into account in determining contributions ($245,000 in 2009 and in 2010). The Company also makes annual supplemental contributions equal to 22% of salary and bonus for Mr. Storch, 16% of salary and bonus for Mr. Romenesko and 5% or 10% of salary and bonus for the other eligible named executive officers.

Executive Perquisites

The Company provides certain executive officers, including its named executive officers, with a limited number of perquisites, as identified in the footnote to the "Other Compensation" column of the Summary Compensation Table. The Company believes these perquisites are reasonable, competitive, and consistent with the Company's overall executive compensation program. The Compensation Committee reviews on an annual basis the types and costs of perquisites provided by the Company to its executive officers.

Employment, Severance and Change in Control Agreements

The Company does not have employment agreements with its executive officers, except for its Chairman and Chief Executive Officer, David P. Storch. See "Compensation Arrangement with Chief Executive Officer" on page 39 for a description of the compensation terms applicable to Mr. Storch under his employment agreement.

The Company has severance and change in control agreements with each of the named executive officers other than Mr. Storch and Mr. Stinson. See "Potential Payments Upon Termination of Employment or a Change in Control of the Company" located elsewhere in this Proxy Statement for a description of these agreements, including a description of the severance and change in control provisions applicable to Mr. Storch under his employment agreement.

Other Compensation Practices

• Stock Ownership Guidelines: Under the Company's stock ownership guidelines, executive officers, including the named executive officers, and directors, are expected to own and retain significant amounts of the Company's stock. The Chief Executive Officer is expected to own Company stock having a value at least three times his base salary; the President and other executive officers are expected to own stock having a value of at least 75% of their base salary within five years of becoming an officer; and directors are expected to own at least 10,000 shares of Company stock within four years of becoming a director. • Equity Grant Practices: The Compensation Committee meets from time to time to consider and act with respect to equity compensation awards for the Company's executive officers. The Compensation Committee typically makes its equity compensation decisions at its July meeting, but it also may grant equity compensation awards to newly hired or newly promoted executive officers at other times during the year. In these cases, the grant date is the date on which the Compensation Committee acts to approve the award, unless the Compensation Committee establishes the grant date at a specified future date. Board and Compensation Committee meetings are generally scheduled a year in advance and without regard to anticipated earnings and other major announcements by the Company. The Company does not time the granting of its equity compensation awards to affect the value of its executive compensation. • Risk Management of Compensation Practices: The Compensation Committee considered whether the Company's compensation policies and practices for its employees, including the named executive officers, were reasonably likely to have a material adverse effect on the Company. In concluding that this was not the case, the Compensation Committee determined that the design and operation of the Company's executive compensation program were consistent with the Company's risk management strategies. In the case of the named executive officers, annual cash incentive compensation awards payable to Messrs. Storch, Romenesko and Poulton in Fiscal 2010 were based on two different metrics: the first — net income — tied to the Company's income statement performance and the second — a leverage ratio — tied to the Company's balance sheet performance, and annual cash incentive compensation awards payable to Messrs. Clark and Stinson were based on three metrics — pre-tax income, cash flow and return on invested capital with respect to the performance of their respective business groups. This balance is also reflected in long-term incentive awards, which in Fiscal 2010 consisted of stock options and performance-based restricted stock, and in Fiscal 2011 will be diversified among stock options, time-based restricted stock and performance-based restricted stock. These long-term equity-based incentive awards contain multi-year vesting periods, thus promoting employee retention, and are linked to the value of the Company's Common Stock, thus aligning management's interest with those of the Company's stockholders. • Deductibility of Executive Compensation: Internal Revenue Code Section 162(m) generally prevents any public company from claiming a deduction for compensation in excess of $1 million for certain executive officers. This deduction limitation, however, does not apply to performance-based compensation that satisfies certain requirements under Section 162(m). The Compensation Committee has determined that it is in the best interests of the Company and its stockholders to structure compensation of executive officers so that compensation will not be subject to the deduction limit to the extent that it can reasonably do so in a manner that provides adequate incentives and allows the Company to attract and retain qualified

The Company maintains the AAR CORP. 162(m) Incentive Goal Program. Under this Program, the annual cash bonuses and performance-based restricted stock awards under the Stock Benefit Plan qualified in Fiscal 2010 as performance-based compensation under Section 162(m). Income recognized upon the exercise of stock options granted under the Stock Benefit Plan also qualifies as performance-based compensation. Base salaries by their nature do not qualify as performance-based compensation.

As required under the United States tax rules, the Company must obtain stockholder approval every five years of the material terms of the performance goals for qualifying performance-based compensation, including annual incentive bonuses. The Company last received stockholder approval of the performance goals under the AAR CORP. 162(m) Incentive Goal Program at the 2006 annual meeting.

2 Salary. Salaries were frozen for the first six months of Fiscal 2010, and salary adjustments for Fiscal 2010 became effective December 1, 2009. Mr. Stinson's Fiscal 2010 salary includes $13,333 paid in October 2009 as retroactive salary that should have been paid in Fiscal 2009. 3 Stock Awards. The amounts in this column reflect the grant date fair value of the performance-based restricted stock awards computed in accordance with FASB ASC Topic 718 and represent the Company's total expense for the grants made to the named executive officers in each of Fiscal 2010, Fiscal 2009 and Fiscal 2008. See Note 3 to the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for an explanation of the assumptions made by the Company in the valuation of these awards. The "Compensation Discussion and Analysis" section of this Proxy Statement contains vesting and other information about the performance-based restricted stock awards. 4 Option Awards. The amounts in this column reflect the grant date fair value of the stock option awards computed in accordance with FASB ASC Topic 718 and represent the Company's total expense for the grants made to the named executive officers in Fiscal 2010 and Fiscal 2009. See Note 3 to the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for an explanation of the assumptions made by the Company in the valuation of these awards.

This column shows the annual cash incentives earned by each named executive officer under the Company's cash incentive plan for its executive officers, including the named executive officers. The "Compensation Discussion and Analysis" section of this Proxy Statement contains additional information about these annual cash incentives (including that these annual cash incentives qualify as performance-based compensation under Section 162(m) of the Code and are thus fully deductible by the Company). 6 Change in Pension Value and Non-Qualified Deferred Compensation Earnings . This column does not include any preferential or above-market earnings on deferred compensation as the Company does not pay such earnings on the deferred compensation of its named executive officers. The "Change in Pension Value and Non-Qualified Deferred Compensation Earnings" column and the "All Other Compensation" column do not include amounts transferred in Fiscal 2008 from the defined benefit portion of the SKERP to the defined contribution portion of the SKERP for Messrs. Storch and Romenesko. 7 All Other Compensation.

Compensation Arrangement with Chief Executive Officer

The Company has an employment agreement with Mr. Storch that was amended and restated on May 31, 2010, for a term commencing May 31, 2010 and ending May 31, 2014, subject to extension by the parties. The amended and restated agreement replaced a prior four-year agreement between the Company and Mr. Storch. The Compensation Committee believes that the amended and restated agreement contains appropriate provisions that, on the one hand, protect the Company and, on the other hand, provide fair compensation to Mr. Storch in recognition of his service and contributions to the Company, including: his 32-year career with the Company (over 20 years in senior management positions); his service as Chief Executive Officer since 1996 and Chairman of the Board since 2005; his knowledge of the commercial aviation and government defense services markets; his understanding of the Company's culture, businesses, employees and customers; and his leadership role in the Company's transformation from a supplier of aircraft parts and aftermarket services for commercial airlines into a leading international provider of products and services to the commercial aviation and government and defense markets, with both front-end manufacturing and after-market support to domestic and international customers.

The amended and restated employment agreement retained most of the provisions in the prior agreement, including the benefits payable upon a termination of employment or a change in control. See "Potential Payments Upon Termination of Employment or a Change in Control of the Company — Employment Agreement of David P. Storch." The agreement extends the term of Mr. Storch's employment with the Company and provides for the following benefits during his employment:

1 The grant date for the performance-based restricted stock awards was April 23, 2010, the date on which the Company's Common Stock traded at an average price greater than $25.06 per share (or 30% higher than the stock price of $19.28 at the beginning of the performance period) for the 20 th consecutive trading day, thus triggering the acceleration of the grants. 2 On July 8, 2008, the Compensation Committee established the performance periods and approved the performance goals for the performance-based restricted stock awards. On that same date, it also authorized the grant of restricted stock upon achievement of the performance goals, with a grant date of the earlier of the last day of the performance period or the date during the performance period when the Company's average stock price was 30% higher than the price at the beginning of the performance period for 20 consecutive trading days. 3 Payouts under the Company's annual incentive cash plan covering the named executive officers were contingent based upon performance for Fiscal 2010, which has now occurred. Thus, the information in these columns reflects the range of potential payouts when the performance goals were set by the Compensation Committee on July 13, 2009. The amounts actually paid under the plan for Fiscal 2010 are set forth in the "Non-Equity Incentive Plan Compensation" column of the Summary Compensation Table. See the "Compensation Discussion and Analysis" section of this Proxy Statement for a description of the incentive cash plan, including the Fiscal 2010 performance goals.

4 The information in these columns shows the range of restricted stock grants that could have been earned by the named executive officers for the Fiscal 2010 performance period and the combined Fiscal 2009 and Fiscal 2010 performance period. The numbers in the "Target" and "Maximum" columns are identical because no more than 100% of the target number of shares may be granted, even for performance in excess of the performance goal targets. The numbers of shares of restricted stock actually granted for the Fiscal 2010 performance period are those listed in the "Target" column above, namely: Mr. Storch, 100,500 shares; Mr. Romenesko, 46,900 shares; Mr. Clark, 23,450 shares; Mr. Poulton, 23,450 shares; and Mr. Stinson, 13,400 shares. 5 No restricted stock, other than performance-based restricted stock, was granted to any named executive officer in Fiscal 2010. 6 This column shows the number of shares of Common Stock that may be issued to the named executive officers upon the exercise of stock options granted by the Compensation Committee on July 13, 2009. 7 The grant date fair value of the performance-based restricted stock awards and stock options was computed in accordance with FASB ASC Topic 718. 8 Messrs. Clark's and Stinson's annual Fiscal 2010 cash incentive opportunities were based upon the pre-tax income, cash flow and return on invested capital performance of their respective business groups. The threshold amounts shown for Messrs. Clark and Stinson represent the compensation payable to them for achievement of 80% of the pre-tax income performance goal target. See "Compensation Discussion and Analysis — Principal Elements of the Executive Compensation Program — Annual Cash Incentive Opportunities" for additional information about the annual cash incentive opportunities in Fiscal 2010 for Messrs. Clark and Stinson.

See Note 6 to the Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for an explanation of the assumptions made by the Company in determining the amounts reported in this column. 3 Messrs. Clark, Poulton and Stinson are not participants in the defined benefit portion of the SKERP. Messrs. Poulton and Stinson do not participate in the Retirement Plan.

SKERP — Defined Benefit Portion

The Company provides supplemental retirement benefits to certain executives and key employees under the SKERP. The SKERP, which is a non-qualified plan, contains a defined benefit portion and a defined contribution portion (discussed below). Only Mr. Storch and Mr. Romenesko participate in the defined benefit portion of the SKERP, the material terms and conditions of which include the following:

Benefit Accruals: Under the defined benefit portion of the SKERP, benefits were accrued until October 1, 2001 pursuant to a formula that provides a monthly single life annuity at retirement at age 65 equal to (i) 1 / 12 of 60% (50% for Mr. Romenesko) of Final Average Earnings less (ii) the monthly benefit payable under the Company's Retirement Plan determined as of October 1, 2001. For purposes of this benefit formula, "Final Average Earnings" is defined as 1 / 5 of a participant's Compensation during the consecutive five years within the last 10 years preceding termination of employment during which such Compensation was the highest, and "Compensation" is defined as the participant's income reported on Form W-2, including pre-tax contributions to the Retirement Savings Plan, reduced by the income attributable to restricted stock and stock options, reimbursements or other expense allowances and fringe benefits. Benefits accrued on and after October 1, 2001 under the defined benefit portion of the SKERP

will accrue pursuant to a formula that provides a monthly single life annuity at retirement at age 65 equal to 1 / 12 of 60% (50% for Mr. Romenesko) of 25% of the percentage increase in the participant's base salary from September 30, 2001 to the date of the participant's termination of employment. The benefits accrued by Messrs. Storch and Romenesko as of May 31, 2006 have been transferred to the defined contribution portion of the SKERP and are held in an account established and maintained thereunder for each participant.

Benefits accrued under the defined benefit portion of the SKERP for all other participants, including Mr. Clark, ceased on October 1, 2001 and were distributed to them in a lump sum as soon as practicable thereafter.

Benefit Entitlement: A participant is eligible to receive the benefit accrued under the SKERP following termination of employment when he attains age 65. If a participant terminates employment after he has attained age 55 and his age plus years of service equal or exceed 62, benefits will be paid on the date of his termination or on a date no later than 15 years after termination of employment, as previously specified by the participant.

Form of Benefit Payment: Each participant has previously elected to have the remainder of his retirement benefit paid in a lump sum. The assumptions set forth in the Company's Retirement Plan will be used to convert the retirement benefits from an annuity payment to a lump sum. The participant may change the time or form of payment in accordance with procedures set forth in the SKERP.

Forfeiture Events: A participant will forfeit the retirement benefit if his employment is terminated due to theft, embezzlement or fraud or willful misconduct in the performance of his duties that materially injures the Company, or if during employment or the one-year period thereafter the participant violates the covenant not to compete contained in the SKERP. As a condition to receiving his retirement benefit, a participant must agree in writing to return his benefit, plus 8% interest, in the event of such forfeiture. The forfeiture provision does not apply if the participant's termination of employment causes benefits to be paid to him under Change in Control provisions of any agreement between the participant and the Company.

Retirement Plan

The Company's Retirement Plan is a tax-qualified pension plan. Benefit accruals ceased under the Retirement Plan with respect to most participants, including the named executive officers, effective June 1, 2005. Neither Mr. Poulton nor Mr. Stinson participates in the Retirement Plan since their dates of hire were after June 1, 2005. The material terms and conditions of the Retirement Plan as they pertain to the other named executive officers are as follows:

Benefit Formula: Until January 1, 2000, benefits were accrued pursuant to a formula that provides a monthly single life annuity at retirement at age 65 equal to 1 1 / 2 % of the participant's Final Average Earnings reduced by the participant's Social Security offset determined under the Plan, multiplied by the participant's years of Credited Service (up to 20). Effective as of January 1, 2000, the Plan was converted to a cash balance type of plan, subject to a "grandfather" provision applicable to certain participants based on age and years of service. An account is maintained for each participant which consists of (i) an opening account balance equal to the then present value of the benefit accrued by the participant under the prior formula as of December 31, 1999, (ii) quarterly contributions made by the Company equal to a percentage of compensation based on the participant's age and years of Credited Service, and (iii) quarterly

Table of Contents

interest credits made by the Company equal to 25% of the 30-year Treasury securities interest rate for the second month preceding the beginning of each quarter. For purposes of the benefit formulae, "Final Average Earnings" and "Compensation" have the same definitions as used in the SKERP, as discussed above.

The benefits under the Retirement Plan generally ceased accruing on June 1, 2005, although the participants' cash balance accounts continue to be credited with interest until the benefits are distributed.

Vesting: Participants are eligible to receive benefits from the Retirement Plan after completing five years of Vesting Service. The named executive officers who participate in the Retirement Plan are fully vested in their benefits.

Payment of Retirement Benefits: Participants can elect to receive their benefits upon termination of employment or they can defer receipt of benefits until normal retirement age (age 65). Any vested participant can elect benefits at any time after termination of employment, with the benefit actuarially reduced to reflect payment prior to age 65. The Retirement Plan also provides for a Disability retirement benefit.

Forms of Benefit Payment: The normal form of benefit payment for a married participant is a joint and 50% survivor annuity, and the normal form of benefit payment for an unmarried participant is a single life annuity. Participants, with spousal consent, if applicable, can waive the normal form of benefit payment and elect to have benefits paid in various annuity forms, which are the actuarial equivalent of the normal form, or in a lump sum.

Retirement Savings Plan: In connection with ceasing benefits under the Retirement Plan, the Company amended its Retirement Savings Plan to provide additional benefits, as described below in the discussion following the Non-qualified Compensation table.

Non-Qualified Deferred Compensation

The Company provides non-qualified deferred compensation benefits under the defined contribution portion of the SKERP. The table below shows the contributions made by each named executive officer and by the Company in Fiscal 2010, the earnings accrued on the named executive officer's account balance in Fiscal 2010, and the account balance as of May 31, 2010.

SKERP — Defined Contribution Portion

The defined contribution portion of the SKERP covers certain executives and key employees, including all of the named executive officers, and provides the portion of a participant's benefit that cannot be paid under the Retirement Savings Plan due to Internal Revenue Code limits, including the limit on the amount of compensation that can be taken into account in determining benefits ($245,000 in 2009 and 2010). The material terms and conditions of the defined contribution portion of the SKERP include the following:

Contributions: Each participant may make an election which satisfies Code Section 409A to contribute a portion of his base salary (up to 75%) for that calendar year that exceeds the Code's compensation limit and a portion of the bonus (up to 75%) paid to him for the Company's fiscal year beginning in such calendar year that exceeds the Code's compensation limit. The Company makes a matching contribution under the SKERP using the formula in the Savings Plan (i.e., 20% of the participant's salary and bonus deferrals made under the SKERP, up to 5% of the participant's salary and bonus), as well as the portion of the Company's retirement benefit and profit sharing contributions that could not be made under the Savings Plan due to the Code's compensation limit. The Company also makes annual supplemental contributions to the accounts of the Chief Executive Officer (22% of base salary and bonus), the President (16% of base salary

and bonus) and other eligible named executive officers (5% or 10% of base salary and bonus). To receive a credit of this contribution, the eligible participant must be employed as of the day before the contribution is made to the SKERP (unless termination of employment is due to death or Disability).

Mr. Storch and Mr. Romenesko also have amounts held in a supplemental account that were transferred from the defined benefit portion of the SKERP, which represent the lump sum value of each participant's accrued benefit as of May 31, 2006 under the defined benefit portion. These amounts are now subject to the terms and conditions of the defined contribution portion of the SKERP.

Vesting: A participant is fully vested in amounts attributable to his own deferral contributions, and vests in all Company contributions, except supplemental contributions, at a rate equal to 33 1 / 3 % for each year of vesting service (subject to full vesting upon age 65, death or Disability). A participant vests in amounts attributable to Company supplemental contributions (i) made prior to October 17, 2007, upon the earlier of age 65, or age 57 with 15 years of service, and (ii) made after October 17, 2007, upon the earlier of age 65, or age 55 with the sum of age and years of service equal to at least 75.

Investments: Each participant's plan accounts are credited with earnings and losses based on investment alternatives made available by the plan committee and selected by the participant from time to time. The investment options currently offered under the SKERP consist of 24 mutual funds including 10 "Life Cycle" fund choices. Participants may change investment elections at any time.

Distributions: Distribution of a participant's accounts is generally made upon the participant's termination of employment or on a date no later than 15 years after termination of employment, as previously specified by the participant. Participants were to elect by December 31, 2005 whether their accounts are to be paid in a lump sum or installments not to exceed 15 years (a participant who failed to make an election will have his account paid in a lump sum). Notwithstanding the foregoing, (i) a participant may elect distribution of the portion of his accounts earned and vested as of December 31, 2004 (and earnings thereon) upon six month's advance written election or if such distribution is subject to a 10% forfeiture; (ii) a participant can change the time and form of payment of the portion of his accounts earned and vested after December 31, 2004 in accordance with procedures set forth in the plan; (iii) a participant can elect a distribution at any time in order to satisfy an unforeseeable hardship (as defined in the plan); and (iv) in the event of a potential Change in Control of the Company (as determined by the Board), the portion of the participant's accounts earned and vested as of December 31, 2004 (including earnings thereon) will be distributed in an immediate lump sum. Distributions to "key employees" as defined in Code Section 409A upon termination of employment will not be paid earlier than six months following such termination.

Forfeiture Events: A participant will forfeit the portion of his plan accounts attributable to Company supplemental contributions and to amounts transferred from the defined benefit portion of the SKERP, if applicable, if his employment is terminated due to theft, embezzlement or fraud or willful misconduct in the performance of his duties that materially injures the Company, or if during employment or the one-year period thereafter the participant violates the covenant not to compete contained in the SKERP. As a condition to receiving such amounts, a participant must agree in writing to return such amounts, plus 8% interest, in the event of such

Retirement Savings Plan

The Retirement Savings Plan is a tax-qualified retirement plan that covers most U.S. employees, including the named executive officers. The material terms and conditions of the Retirement Savings Plan are as follows:

Contributions: A participant can elect to defer 1% to 75% of his Compensation on a pre-tax basis, up to a maximum of $16,500 for 2010, or $22,500 if age 50 or older. Participation for non-union employees hired after June 1, 2007 is automatic, unless the participant affirmatively elects not to participate or to participate with a different deferral amount. The automatic deferral rate for participants hired after June 1, 2007 and prior to June 26, 2009 is 3% of compensation, and the automatic deferral rate for participants hired on or after June 26, 2009 is 5%, with annual increases of 1%. The Company provides a matching contribution, a profit sharing contribution and a retirement benefit contribution. The current matching contribution is made as of each payroll period in an amount equal to 20% of the participant's pre-tax contributions (up to 5% of compensation) to the Plan for such payroll period. The profit sharing contribution is made as of the end of each calendar year and is based on the participant's pre-tax contributions and the economic performance of the participant's operating unit and is equal to a percentage of the participant's compensation, up to 4%. The retirement benefit contribution, which is also made as of the end of each calendar year, was added to the Plan, effective June 1, 2005, and is equal to a percentage of compensation (up to 4%) based on the participant's age and years of credited service. A participant must have earned a year of service to be eligible for a retirement benefit contribution, and generally must be employed on the last day of the calendar year to receive a profit sharing contribution. Compensation for purposes of determining contributions includes cash compensation shown as income on the participant's Form W-2, reduced by pre-tax contributions to the plan and excluding the income attributable to restricted stock options, reimbursements or other expense allowances and fringe benefits and subject to the Code's compensation limit ($245,000 for 2009 and 2010).

Investments: Each participant's plan accounts are credited with earnings and losses based on investment alternatives made available by the plan committee and selected by the participant from time to time. The investment options currently offered under the plan consist of 24 mutual funds including 10 "Life Cycle" fund choices. Participants may change investment elections at any time.

Vesting: Participants hired prior to July 1, 1999 are fully vested in their accounts under the plan. Participants hired on or after January 1, 1999 are fully vested in their pre-tax contribution accounts, and vest in the Company contribution accounts at a rate equal to 33 1 / 3 % for each year of vesting service (subject to full vesting upon age 65, death or Disability).

Distributions: Participants can elect distributions of the plan accounts upon termination of employment, in a lump sum, an eligible rollover distribution, or, if early or normal retirement has been attained, in installments not to exceed 15 years.

Potential Payments Upon Termination of Employment or a Change in Control of the Company

The Company provides certain benefits to eligible employees upon certain types of termination of employment, including a termination of employment involving a Change in Control of the Company. These benefits are in addition to the benefits to which the employees would be entitled upon a termination of employment generally (i.e., vested retirement benefits accrued as of the date of termination, stock options and restricted stock that are otherwise vested as of the date of termination and the right to elect continued health coverage pursuant to COBRA). These benefits as they pertain to the named executive officers are as described and set forth in the tables on pages 41-42.

Mr. Storch is also entitled to the benefits described above under "Termination of Employment — Prior to Change in Control" if he terminates his employment for Good Reason after the 30 th day following the 24 th month after a Change in Control. The employment agreement's non-compete provisions do not apply in the case of a termination of employment following a Change in Control.

General: Regardless of whether a Change of Control is involved:

In any event, payments under the employment agreement in connection with Mr. Storch's termination of employment that would be considered deferred compensation under Section 409A of the Internal Revenue Code will be delayed for six months following such termination to the extent necessary to comply with Section 409A.

For purposes of Mr. Storch's employment agreement:

"Change in Control" means (i) a person's acquisition of more than 35% of the voting power of the Company's outstanding stock, (ii) a merger or consolidation of the Company that results in the holders of the voting stock immediately prior thereto holding less than 60% of the voting stock of the resulting or surviving entity, (iii) a sale of substantially all of the Company's assets other than to an entity at least 80% owned by the Company, or (iv) the election, without the consent of the incumbent Board, of a majority of the directors then in office.

Termination of Employment — Prior to a Change in Control: If a Change in Control of the Company has not occurred and the executive's employment is terminated by the Company other than for Cause, he is entitled to (i) continued salary for 12 months or, if earlier, until he obtains comparable employment, (ii) any earned bonus not yet paid for the preceding fiscal year, and (iii) a pro-rata portion of the bonus that would have been paid to the executive had he remained employed until the end of the fiscal year in which the termination occurs. Any bonus will be paid in a lump sum on the later of the time bonuses are paid to other officers and the end of the severance period (with interest at the prime rate plus 1% from the earlier of such dates). If the executive terminates his employment, or if the Company terminates the executive's employment for Cause, the Company may, but is not required to, pay the above-described severance benefits. Severance payments will cease if the executive breaches the confidentiality or non-compete provisions in the agreement, which are in effect for the one-year severance period.

Termination of Employment — Following a Change in Control: If the executive's employment is terminated within 18 months (24 months for Mr. Clark) following a Change in Control by the Company other than for Cause or Disability or by the executive for Good Reason, or if the executive's employment terminates for any reason other than Disability or death during the 30-day period following the 18 th month (24 th month for Mr. Clark) after a Change in Control, he is entitled to (i) an immediate lump sum payment equal to the sum of (A) any unpaid salary and bonus earned for the preceding fiscal year, (B) a pro rata portion of the bonus that would have been paid to the executive had he remained employed until the end of the fiscal year and as if all performance targets had been met (including the value of any restricted stock granted in lieu of bonus), and (C) two or three times base salary and cash bonus (depending upon the executive involved) for either the most recently completed fiscal year prior to the termination or the preceding fiscal year, whichever produces the higher amount, (ii) continued coverage for the

executive and his dependents under the Company's welfare and fringe benefit plans (medical, dental and life insurance plans for Mr. Clark) for three years following termination of employment (the executive and his dependents can elect continued medical and dental coverage pursuant to COBRA at the end of such two- or three-year period), (iii) an immediate lump sum payment equal to the actuarial equivalent of the additional benefits that would be earned under the Company's retirement plans with three additional years of service and, for Mr. Romenesko, a gross-up payment to cover any related income tax liability, (iv) Company-paid outplacement services for the earlier of 18 months or the attainment of new employment (up to a maximum Company expense of 3.5% of the amount paid to the executive pursuant to (i)(C) above), (v) reasonable legal fees incurred by the executive in enforcing the agreement, and (vi) a gross-up payment to cover any excise and related tax liability arising under Section 280G of the Internal Revenue Code as a result of any payment or benefit arising under the agreement. The agreements' non-compete provisions do not apply in the case of a termination of employment following a Change in Control.

Termination of Employment — Disability: If the executive's employment terminates due to Disability , the executive will receive payment pursuant to the Company's disability plans then in effect and will continue to receive coverage under the Company's medical, dental and life insurance plans for three years following such termination.

Acceleration of Equity Awards: The severance and change in control agreements also provide that upon any Change in Control, all outstanding stock options and restricted stock will vest immediately.

For purposes of the severance and change in control agreements:

"Change in Control" means (i) a person's acquisition of more than 20% of the voting power of the Company's outstanding stock, (ii) a merger or consolidation of the Company that results in the holders of the voting stock immediately prior thereto holding less than 60% of the voting stock of the resulting or surviving entity, (iii) a sale of substantially all of the Company's assets other than to an entity at least 80% owned by the Company, or (iv) the election, without the consent of the incumbent Board, of the lesser of three directors or a majority of the directors then in office.

"Cause" means the executive's (i) dishonesty, intentional breach of fiduciary duty, or intentional wrongdoing, (ii) disregard of a material and proper direction from the Board, or (iii) material breach of the agreement that is not cured within 10 days of receipt of notice from the Company.

"Disability" means a physical or mental condition that has prevented the executive from substantially performing his duties under the agreement for a period of 180 days and that is expected to continue to render the executive unable to substantially perform his duties for the remaining term of the agreement on a full-time basis.

"Good Reason" means (i) a material reduction in the nature or scope of the executive's duties or responsibilities, or in his compensation (including benefits), (ii) if Mr. Storch is not the Chief Executive Officer at the time of termination, the executive's determination that as a result of a material change in employment circumstances he is unable to adequately carry out his duties, or (iii) a relocation of the executive's primary place of employment by more than 100 miles.

In any event, payments under the agreements in connection with termination of employment that would be considered deferred compensation under Section 409A of the Internal Revenue Code

will be delayed for six months following such termination to the extent necessary to comply with Section 409A.

Split Dollar Insurance Agreements

The Company has entered into split dollar life insurance agreements with certain key employees, including Messrs. Storch, Romenesko and Clark. Under the agreements, the employees own the policies, except for the cash value portion of the policies owned by the Company. The Company funds the annual insurance premiums for the policies during the term of the agreement subject to reimbursement from the cash value or death benefit proceeds of the policies. Upon a Change in Control of the Company (as defined above), the Company will prepay all premiums, plus any amounts necessary for the cash value and death benefits to be at the same level at the Change in Control date. If the executive's employment terminates after a Change in Control and benefits are paid under the severance and change in control agreements, the Split Dollar Agreements will continue for the severance period.

Stock Benefit Plan

A named executive officer's termination of employment can result in enhanced benefits under the Company Stock Benefit Plan, depending on the reason for such termination:

Stock Options: If termination is due to Retirement (as defined in the Plan), options to continue to vest in accordance with the vesting schedule and can be exercised until the expiration date, except that if death occurs before the award expires, then unvested stock options are forfeited. If death occurs within three months of Retirement, vested options can be exercised until the earlier of one year after death or the option expiration date, and if death occurs after three months from Retirement, vested options can be exercised until the option expiration date. If termination is due to Disability (as defined in the Stock Benefit Plan), options continue to vest and are exercisable until the earlier of one year after termination of employment and the option expiration date, except that if death occurs before the award expires, then unvested options are forfeited and vested options are exercisable for the period described herein. If death occurs during, or within three months after termination of, employment for reasons other than Cause, then unvested options are forfeited and vested options are exercisable until the earlier of one year after death or the option expiration date.

Restricted Stock Awards: If the termination is due to Retirement, restricted stock awards continue to vest in accordance with their vesting schedule. If the termination is due to Disability (as defined in the Stock Benefit Plan) or death on or before the third anniversary of the date of grant, then the difference between one-half of the total award shares and the number of shares already vested will vest as of such termination. If the termination is due to Disability or death after the third anniversary of the date of grant, all awards shares will vest as of such termination.

The Stock Benefit Plan has change in control provisions that apply to participants who do not have a severance and change in control agreement. Upon a Change in Control of the Company (as defined in the Stock Benefit Plan) that does not have prior written approval of the Board, all options and restricted stock awards will fully vest. Upon a change in control that has the approval of the Board, the Compensation Committee has the discretion to either provide for full vesting of options and restricted stock awards or grant replacement awards with respect to the successor company's stock.

VII. PROPOSAL 2 APPROVAL OF THE AAR CORP. SECTION 162(m) ANNUAL CASH INCENTIVE PLAN

The Board of Directors of the Company has approved, upon the recommendation of the Compensation Committee and subject to the approval of the Company's stockholders at the 2010 Annual Meeting of Stockholders, the AAR CORP. Section 162(m) Annual Cash Incentive Plan (the "Plan").

Stockholders are being asked to approve the Plan to ensure that annual cash bonuses paid to Plan participants will qualify as "performance-based" compensation under Section 162(m) of the Code and thus be fully deductible by the Company for federal income tax purposes. Section 162(m) and related guidance generally preclude a publicly traded company from taking a tax deduction for compensation in excess of $1 million paid to certain executives. These executives are the public company's chief executive officer and the three other highest paid executives, other than the chief financial officer, who are the named executive officers listed in the Summary Compensation Table of the public company's annual proxy statement. The deduction limitation is subject to an exception for "performance-based" compensation that meets certain requirements, including a requirement that the "material terms of the performance goals" applicable to these named executive officers must be disclosed to and approved by stockholders before any compensation is paid to them. Stockholder approval of the Plan will constitute approval of the Plan's "material terms of the performance goals" within the meaning of the regulations under Section 162(m).

If the Plan is approved by stockholders, it will be effective for Fiscal 2011, beginning June 1, 2010 and ending May 31, 2011, and will remain in effect for each fiscal year thereafter until terminated by the Board. No compensation will be paid under the Plan to the named executive officers covered by the Plan unless the Plan is approved by stockholders.

The following is a summary of the Plan. It is qualified in its entirety by reference to the full text of the Plan, which is attached as Appendix B to this proxy statement.

Description of the Plan

General. The Plan is intended to work in conjunction with the Company's Short-Term Incentive Plan, pursuant to which annual cash bonuses are paid to eligible employees only upon the attainment of certain performance goals designated by the Compensation Committee. The purpose of the Plan is to set a ceiling on the performance-based bonuses that are paid under the Short-Term Incentive Plan so that such bonuses will meet the deductibility requirements of Section 162(m).

Administration. The Plan is administered by the Compensation Committee, or such other committee appointed by the Board that is comprised of at least two "outside directors" as defined in Section 162(m) (the "Committee"). The Committee has full authority to select the employees eligible for bonus awards under the Plan, determine when an employee's participation in the Plan will begin, determine the amounts payable under the Plan, and make all other decisions necessary for the proper administration of the Plan.

Eligibility. The Plan covers the Chief Executive Officer and the three other highest paid employees (other than the Chief Financial Officer) who are listed as named executive officers in the Company's proxy statement. The Chief Financial Officer is not subject to Section 162(m)

ZEQ.=1,SEQ=63,EFW="2199972",CP="AAR CORP",DN="1",CHK=275332,FOLIO='59',FILE='DISK131:[10ZBY1.10ZBY74501]DO74501A.;68',USER='CGONCE',CD='27-AUG-2010;11:56'

Table of Contents

under regulations issued thereunder. The Committee also has the discretion to designate other employees as covered under the Plan. For Fiscal 2011, only the four named executive officers (other than the Chief Financial Officer) will be covered by the Plan. These executives are Messrs. Storch, Romenesko, Clark and Stinson.

Performance Goal and Determination of Awards. The performance goal under the Plan upon which awards, if any, will be based is the Company's net income for a given fiscal year. The Plan establishes a maximum award opportunity for each category of Plan participants, expressed as a percentage of the Company's net income for the applicable fiscal year: for the Chairman and Chief Executive Officer — 5% of net income; for the President and Chief Operating Officer — 3% of net income; and for each other Plan participant — 2% of net income. Following completion of the fiscal year, the Committee will determine the amount of each participant's maximum award opportunity solely on the basis of the Company's net income for that Plan year.

The Committee has the discretionary authority to reduce the maximum award opportunity amount, taking into account individual and/or corporate performance or such other factors as it deems appropriate, in order to determine the actual bonus award to be paid to each Plan participant. The Committee intends to exercise that discretion and thus does not anticipate that any participant will receive the maximum award opportunity amount under the Plan. For Fiscal 2011, the Committee has established performance criteria for each participant under the Short-Term Incentive Plan, and intends to exercise its negative discretion under the Plan to provide that the actual bonuses to be paid to Plan participants will be the bonuses determined based on performance under the Short-Term Incentive Plan. The Plan prohibits the Committee from increasing a participant's award above a participant's maximum award opportunity.

Payment of Awards. Bonuses will be paid in cash to participants (or their beneficiaries in the event of death) prior to August 15 following the fiscal year for which the bonus was earned. In lieu of receiving the bonus payment directly, a participant can make an advance election to defer the bonus payment in accordance with the Company's Supplemental Key Employee Retirement Plan.

Bonuses payable under the Plan for Fiscal 2011 and future years cannot currently be determined because they will depend on the attainment of the Company's net income goal and of specified performance goals under the Short-Term Incentive Plan, as well as the exercise of negative discretion by the Committee to limit or reduce a participant's maximum award opportunity amount. If the Plan had been in effect for Fiscal 2010 when the Company had net income of $44.6 million, the bonuses that would have been paid to the participants under the Plan are the same amounts that were actually paid to them under the Short-Term Incentive Plan for Fiscal

Amendment or Termination. The Board may amend or terminate the Plan at any time, without the consent of participants and without the approval of the stockholders of the Company, provided that no amendment or termination shall affect the Company's obligation to pay any bonus amount after it has been earned by a participant.

VIII. AUDIT COMMITTEE REPORT FOR FISCAL 2010

On May 31, 2010, the Audit Committee was comprised of six independent directors. The Board has determined that each member of the Audit Committee is independent within the meaning of the applicable SEC regulations, NYSE rules and the Company's Categorical Standards and Policy for Determining Director Independence.

The Company's management is primarily responsible for the Company's financial statements and the quality and integrity of the reporting process and systems of internal control. The Company's independent registered public accounting firm is responsible for auditing the Company's financial statements and the effectiveness of internal controls over financial reporting and for expressing opinions thereon. The Audit Committee has the authority to obtain advice and assistance from outside legal, accounting or other advisors as the Audit Committee deems necessary to carry out its duties with funding from the Company.

In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed the Company's audited financial statements for the fiscal year ended May 31, 2010 with the Company's management and representatives of the Company's independent registered public accounting firm, including a discussion of the reasonableness of significant judgments and accounting estimates, and clarity of disclosures in the financial statements. The Audit Committee also reviewed with management and the independent registered public accounting firm the preparation of the financial statements and related disclosures contained in the Company's

earnings announcements and quarterly reports. Management has represented to the Audit Committee that the Company's financial statements were prepared in accordance with U.S. generally accepted accounting principles ("GAAP") and the independent registered public accounting firm has expressed an opinion based on their audit that the financial statements are in conformance with GAAP in all material respects. The Audit Committee is not responsible for planning or conducting audits, or the determination that the Company's financial statements are complete and accurate and in accordance with GAAP. That is the responsibility of management and the independent registered public accounting firm.

The Audit Committee reviewed and discussed with the independent registered public accounting firm and management the overall scope and plans for the audit, the quality, adequacy and assessment of the effectiveness of internal controls over financial reporting, and the Internal Audit Department's management, organization, responsibilities, budget and staffing. The Audit Committee also met with the independent registered public accounting firm representatives without management present and discussed the results of their audits, their evaluation of the Company's internal controls over financial reporting, disclosure controls and the overall quality (not just acceptability) of the Company's accounting policies and financial reporting.

The Audit Committee also discussed with the representatives of the independent registered public accounting firm the matters required to be discussed by Statement on Auditing Standards, No. 61, Communications with Audit Committees, as amended by SAS 90 Audit Committee Communications, the independent registered public accounting firm's independence from the Company and its management, including the matters in the written disclosures and letter furnished to the Audit Committee by the independent registered public accounting firm and required by applicable requirements of the Public Company Accounting Oversight Board, and determined that the non-audit services provided to the Company by the independent registered public accounting firm are compatible with maintaining the independent registered public accounting firm's independence.

In reliance on its review of the audited financial statements and the discussions referred to above 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 be included in the Company's Annual Report on Form 10-K for the year ended May 31, 2010 for filing with the SEC.

The Audit Committee also reviewed and assessed the adequacy of the Audit Committee Charter and conducted an Audit Committee self-assessment in which it concluded that the Committee operates effectively and successfully carried out all of its Charter responsibilities.

Respectfully submitted,

Audit Committee

APPENDIX A — AAR CORP. CATEGORICAL STANDARDS AND POLICY FOR DETERMINING DIRECTOR INDEPENDENCE

It is the policy and practice of AAR CORP. (the "Company") that the directors of the Company, when carrying out their duties, must exercise their independent judgment in good faith and in the best interests of the Company and its stockholders as a whole.

In addition, it is the policy of the Company that a majority of its directors, and all directors serving on the Audit Committee, Compensation Committee and Nominating and Governance Committee, shall be "independent," as determined by the Board in accordance with the independence standards of the New York Stock Exchange ("NYSE").

At least once each year, the Board shall review the "independence" of each director and any nominee for director and make a determination whether the director or nominee has any material relationship with the Company (either directly or indirectly as a partner, shareholder, or officer of an organization that has a relationship with the Company) that would impair the director's ability to exercise independent judgment as a member of the Board.

To assist it in determining a director's "independence," the Board has adopted the following categorical standards for determining director "independence" status with respect to service as a director*:

COMMAND=ADD_LINERULETXT,NOSHADE COLOR="#000000" SIZE="1.0PT" WIDTH="10%" ALIGN="LEFT" * The foregoing categorical standards shall be deemed to be automatically updated to reflect any changes made to the NYSE listing standards and shall be interpreted in the same manner as such standards. 1. For purposes of these categorical standards, the "Company" includes each of the Company's subsidiaries and "immediate family member" means a person's spouse, parents, children, siblings, mothers- and fathers-in-law, sons- and daughters-in-law, brothers- and sisters-in-law, and anyone (other than domestic employees) who shares the person's home; provided, that any such persons who no longer have any such relationship as a result of legal separation or divorce, or death or incapacitation, shall not be considered immediate family members. 2. No director shall be independent if he/she does not meet the independent standards adopted from time to time by the NYSE. Specifically, a director will not be "independent" if:

Table of Contents

  1. In determining director independence, the Board will give consideration to all known relevant facts and circumstances. 4. Notwithstanding the foregoing, if a director or his/her immediate family member has another significant relationship with the Company that is not described in Section 2, or, at any time, is the subject of a written request by any director to the Chairman of the Nominating and Governance Committee requesting a review of another director's independent status and stating the reasons therefor, then the Board of Directors will determine whether that director's relationship is a "material relationship" that would impair the director's ability to exercise independent judgment as a member of the Board. 5. Members of the Audit Committee must satisfy the enhanced "independence" criteria under applicable rules of the Securities and Exchange Commission and the New York Stock Exchange from time to time. In particular, the following enhanced "independence" qualifying criteria shall apply with respect to directors selected for service on the Audit Committee:

If a Participant's position changes during a Plan Year, the Participant's Award opportunity will be based on the position held on the last day of the Plan Year, and if a Participant holds two different positions concurrently at the end of a Plan Year, the Participant's Award opportunity will be based on the position that provides the higher Award opportunity. All Awards under the Plan shall be granted upon terms approved by the Committee.

4.2 Committee Certification. As soon as reasonably practicable after the end of each Plan Year to which an Award relates, the Committee shall certify, in writing, the amount of payment to be made to each Participant with respect to his or her Award. The Committee may in its discretion authorize payment to a Participant of less than the maximum Award opportunity and may provide that a Participant will not receive any payment with respect to an Award. In exercising its discretion, the Committee may consider such factors as it deems appropriate. In no event may the Committee authorize payment at more than the maximum Award opportunity set forth in Section 4.1.

4.3 Payment of Awards. Payment of Awards shall be made in cash at such times and on such terms as are determined by the Committee in its sole and absolute discretion, but in no event later than two and one-half months following the end of the Plan Year to which the Award relates.

5.2 Amendment or Termination of Plan. The Board may at any time suspend or terminate the Plan and may amend it from time to time in such respects as the Board may deem advisable, subject to any requirement for stockholder approval imposed by applicable law, including Section 162(m) of the Code; provided, however, that no amendment, suspension or termination of the Plan shall, without the consent of the person affected thereby, materially, adversely alter or impair any rights or obligations with respect to any Award payment previously certified by the Committee in accordance with Section 4.2 of the Plan.

VI. GENERAL PROVISIONS

6.4 Successors. All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

6.5 Severability. If any provision of the Plan shall be held illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provisions had not been included.
