ABOUT THE MEETING

 
Q. What am I voting on?

A.  Proposal 1:  Approval of amendments to our certificate of incorporation and bylaws to eliminate the classification of our Board of Directors.

  Proposal 2:  Election of eleven directors to serve until the next annual meeting of stockholders, or until their successors are duly elected and qualified.
 
  Proposal 3:  Solely in the event that the stockholders do not approve Proposal 1 (elimination of our classified Board of Directors), to elect four Class II directors to hold office until the 2007 annual meeting of stockholders or until their respective successors are duly elected and qualified.

      Proposal 4: Approval of the United Auto Group Management Incentive Plan.

 
Q. Who can vote?

A.  Common stockholders of United Auto Group, Inc. as of the close of business on the record date, April 1, 2004, can vote at the annual meeting. Each share of our common stock gets one vote.

 
Q. How do I vote before the meeting?

A.  By completing, signing and returning the enclosed proxy card.

 
Q. May I vote at the meeting?

A.  You may vote your shares at the meeting if you attend in person. If you hold your shares through an account with a bank or broker, you must obtain a legal proxy from the bank or broker in order to vote at the meeting. Even if you plan to attend the meeting, we encourage you to vote your shares by proxy.

 
Q. Can I change my mind after I vote?

A.  You may change your vote at any time before the polls close at the meeting. You may do this by (1) signing another proxy card with a later date and returning it to us prior to the meeting or (2) voting at the meeting if you are a registered stockholder or have obtained a legal proxy from your bank or broker.

 
Q. What if I return my proxy card but do not provide voting instructions?

A.  Proxies that are signed and returned but do not contain instructions will be voted (1) FOR the elimination of the classified Board of Directors (2) FOR the election of the eleven nominees for director, (3) solely in the event the stockholders do not approve the elimination of the classified Board of Directors, FOR the election of the four nominees for Class II director, (4) FOR the approval of United Auto Group Management Incentive Plan, and (5) in accordance with the best judgment of the named proxies on any other matters properly brought before the meeting.

 
Q. Will my shares be voted if I do not provide my proxy instruction form?

A.  If you are a registered stockholder and do not provide a proxy, you must attend the meeting in order to vote your shares. If you hold shares through an account with a bank or broker, your shares may be voted even if you do not provide voting instructions on your instruction form. Brokerage firms have the authority under the New York Stock Exchange rules to vote shares for which their customers do not provide voting instructions on certain “routine” matters. The election of directors is considered a routine matter for which brokerage firms may vote without specific instructions. The approval of the management incentive plan and elimination of our classified Board of Directors are not routine matters. When a proposal is not a routine matter and the brokerage firm has not received voting instructions from the beneficial owner of the shares with

1


Table of Contents

respect to that proposal, the brokerage firm cannot vote the shares on that proposal. This is called a “broker non-vote”.
 
Q. May stockholders ask questions at the meeting?

A.  Yes. Representatives of the Company will answer stockholder’s questions of general interest at the end of the meeting. In order to give a greater number of stockholders an opportunity to ask questions, individuals or groups will be allowed to ask only one question and no repetitive or follow-up questions will be permitted.

 
Q. How many votes must be present to hold the meeting?

A.  Your shares are counted as present at the meeting if you attend the meeting and vote in person or if you properly return a proxy. In order for us to conduct our meeting, a majority of our outstanding shares of common stock as of April 1, 2004 must be present in person or by proxy at the meeting. This is referred to as a quorum. Abstentions and broker non-votes will be counted for purposes of establishing a quorum at the meeting.

 
Q. How many votes are needed to approve the Company’s proposals?

A.  The nominees receiving the highest number of “For” votes will be elected as directors. This number is called a plurality. Shares not voted, whether by marking “Abstain” on your proxy card or otherwise, will have no impact on the election of directors. Approval of the United Auto Group Management Incentive Plan requires that a majority of the votes cast at the meeting be voted “For” the proposal. Approval of the elimination of our classified Board of Directors requires the approval of two-thirds of the shares eligible to vote on the record date.

 
Q. What is the Company’s policy regarding director attendance at the annual meeting?

A.  We encourage all of our directors to attend the annual meeting. In 2003, all of our directors attended the annual meeting.

PROPOSAL 1 – APPROVAL OF AMENDMENTS TO OUR CERTIFICATE OF INCORPORATION

AND BYLAWS TO ELIMINATE THE CLASSIFICATION OF OUR BOARD OF DIRECTORS.

      The Board of Directors is currently separated into three classes. Each year, the stockholders are requested to elect the directors comprising one of the classes for a three-year term. Currently, the term of the Class II directors is set to expire in 2004 at this year’s annual meeting. The term of the Class III directors is set to expire in 2005 and the term of the Class I directors is set to expire in 2006. Because of the classified board structure, stockholders have the opportunity to vote on only roughly one-third of the directors each year.

      The Board of Directors has approved and is proposing to the stockholders amendments to our certificate of incorporation and bylaws to eliminate the classified board structure. If the stockholders approve this proposal, the terms of all directors will expire at the annual meeting of stockholders each year and their successors will be elected for one-year terms that will expire at the next annual meeting. The text of the actual amendments to the certificate of incorporation and bylaws are set forth in Annex A.

      The sense of the Board of the Directors is that stockholders should have the opportunity to vote on all directors each year and that elimination of the classified board structure will be an effective way to maintain and enhance the accountability of the Board of Directors. In making this determination the Board of Directors has considered that removing the classified Board of Directors will have the effect of accelerating the time required for a majority stockholder or group of stockholders to replace a majority of the Board of Directors in any single year. Under a classified Board of Directors, a majority of the Board of Directors may be replaced only after two years. In addition, under Delaware law, directors of a classified board of directors may be removed only for cause. This limitation on removal of directors by cause would no longer apply if this proposal is approved.

      The Company’s largest stockholder, Penske Corporation, together with its affiliates, beneficially owns approximately 41% of our outstanding common stock, and through a stockholders agreement, controls approximately 57% of the Company’s outstanding common stock as to the election of directors, subject to certain restrictions. See “Related Party Transactions” for a description of the stockholders agreement. We have been informed by representatives of Penske Corporation that they have no plan or intention of replacing any directors and we are not aware of any attempt of any other person or group of persons intending to seek the removal of any directors.

      If the stockholders approve this proposal, each of the eleven directors who are elected at the annual meeting will be elected for a one-year term that will expire at next year’s annual meeting. The entire Board of Directors will be subject to election at next year’s annual meeting of stockholders. Approval of the amendments to the certificate of incorporation and bylaws to eliminate the classified Board of Directors requires the affirmative vote of at least 66 2/3% of the shares of common stock issued and outstanding as of the record date, or approximately 30.8 million shares.

      If the stockholders vote to approve this proposal, it will become effective upon the filing of an amendment to the certificate of incorporation with the Secretary of State of the State of Delaware. We intend to file the amendment immediately after the requisite vote is obtained. The stockholders will then be asked to vote on Proposal 2 and a vote on Proposal 3 will not be taken.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” ELIMINATION OF OUR CLASSIFIED BOARD OF DIRECTORS.

PROPOSAL 2 — ELECTION OF DIRECTORS

      The second proposal to be voted on at the annual meeting is the election of the following eleven directors, each of whom is recommended by our Board of Directors. Biographical information about each of these nominees is included below.

      If the stockholders approve Proposal 1 (elimination of our classified Board of Directors) at the annual meeting, each of these nominees will be elected to serve a one-year term and will be subject to reelection at

Table of Contents

next year’s annual meeting. See Proposal 1 above. If Proposal 1 is not approved, stockholders will not be asked to vote for this proposal, and instead will vote for Proposal 3.

      Pursuant to a stockholders agreement, certain of our stockholders affiliated with Roger S. Penske and Mitsui & Co., Ltd. have agreed to vote together to elect members to our Board of Directors. See “Related Party Transactions” for a description of the stockholders agreement.

Mr. Yoshida attended less than 75% of the 2003 Board and committee meetings.

      Our Board of Directors has four standing committees: the Audit Committee, the Compensation and Management Development Committee, the Executive Committee and the Nominating and Corporate Governance Committee. The Board of Directors approved a charter for each of the Audit, Compensation and Management Development, and Nominating and Corporate Governance committees, which charters are available on our website, www.unitedauto.com. The principal responsibilities of each committee are described in the following paragraphs.

      Audit Committee. Our Audit Committee is comprised of Michael Eisenson (Chairman), John Barr and Ronald Steinhart. The purpose of the Committee is to assist the Board of Directors in fulfilling its oversight responsibility relating to (i) the integrity of our financial statements and financial reporting process and our systems of internal accounting and financial controls; (ii) the performance of the internal audit function;

6


Table of Contents

(iii) the annual independent audit of our financial statements, the engagement of the independent auditors and the evaluation of the independent auditors’ qualifications, independence and performance; and (iv) the fulfillment of the other responsibilities set out in the Audit Committee charter.

      The Board of Directors has confirmed that all members of the Audit Committee are “independent” and “financially literate” within the meaning of the New York Stock Exchange rules and applicable law and each is an “audit committee financial expert”. Mr. Steinhart serves on the audit committee of three other entities. In 2004, the Board of Directors determined that Mr. Steinhart’s simultaneous service on three audit committees in addition to our Audit Committee would not impair his ability to effectively serve as a member of our Audit Committee.

      Compensation and Management Development Committee. Our Compensation and Management Development Committee is comprised of H. Brian Thompson (Chairman) and William Lovejoy. The purpose of the Committee is to discharge the responsibility of the Board of Directors relating to compensation of the Company’s directors, executive officers and such other employees as the Committee may determine and related matters.

      Executive Committee. Our Executive Committee is comprised of Roger Penske (Chairman), Michael Eisenson, James Hislop and Lucio Noto. Our Executive Committee’s primary function is to assist our Board of Directors by acting upon matters when the Board of Directors is not in session. The Executive Committee has the full power and authority of the Board of Directors, except to the extent limited by law or our certificate of incorporation or bylaws.

      Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee is comprised of Eustace Mita (Chairman) and H. Brian Thompson. The purpose of the Committee is to identify individuals qualified to become members of the Board of Directors, to recommend Director nominees for each annual meeting of stockholders and nominees for election to fill any vacancies on the Board of Directors and to address related matters. The Committee also develops and recommends to the Board of Directors corporate governance principles applicable to the Company and is responsible for leading the annual review of the Board’s performance. Upon their election at our annual meeting, each of the Committee members will be independent under the New York Stock Exchange rules.

      Other Corporate Governance Matters. The Nominating and Corporate Governance Committee also makes recommendations concerning our corporate governance guidelines, which are posted on our website, www.unitedauto.com. These guidelines are also available in print to any stockholder who requests them by calling our investor relations department at 248-648-2500.

      One of our governance principles is that we must have a “Lead Director,” who shall be responsible for coordinating the activities of the other outside Directors, including the establishment of the agenda for executive sessions of the outside Directors. Our Lead Director is currently H. Brian Thompson. He may be contacted by leaving a message at the following telephone number: 800-469-1634. All messages will be reviewed by our General Counsel’s office and all (other than frivolous messages) will be forwarded to the Lead Director.

      We have also adopted a Code of Business Conduct and Ethics, applicable to all of our employees. This code also is available in print to any stockholder who requests it by calling our investor relations department at 248-648-2500. We plan to disclose waivers for our executive officers or directors from the code on our website, www.unitedauto.com.

      Upon their election at the annual meeting, a majority of our Board of Directors will be independent, as defined by the New York Stock Exchange rules. Under the New York Stock Exchange rules, if a company is “controlled” it need not have a majority independent Board of Directors or solely independent compensation or nominating committees. We are a “controlled company” because Penske Corporation and its affiliates, and Mitsui & Co. and its affiliates collectively own more than fifty percent of our voting stock. These entities are considered a group due to the provisions of the stockholders agreement between these parties described under “Related Party Transactions.” Even though we are a “controlled company”, upon the election of our directors

Table of Contents

at the annual meeting, we will be fully compliant with the New York Stock Exchange rules for non-controlled companies.

      The Nominating and Corporate Governance Committee believes that candidates for director should have certain minimum qualifications, including having personal integrity, loyalty to UnitedAuto and concern for its success and welfare, willingness to apply sound and independent business judgment and time available for UnitedAuto matters. Experience in one of the following is also desired: high level of leadership experience in business or administration, breadth of knowledge concerning issues affecting United Auto, willingness to contribute special competence to board activities, accomplishments within the director’s respective field and some basic experience reading and understanding financial statements. The Committee retains the right to modify these qualifications from time to time.

      The Nominating and Corporate Governance Committee’s process for identifying and evaluating nominees is as follows: in the case of incumbent directors whose terms of office are set to expire, the Committee reviews such directors’ overall service to the Company during their term. In the case of new director candidates, the Committee first determines whether the nominee would be independent. The Committee uses its network of contacts to compile potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Committee then meets to discuss and consider such candidates’ qualifications and then chooses a candidate by majority vote. Mr. Ishikawa is the only nominee who is not currently a Director. Mr. Ishikawa was recommended to the Committee by our current Board member, Motokazu Yoshida.

      The Committee will consider director candidates nominated by stockholders. Stockholder nominees should be addressed to Corporate Secretary, United Auto Group, 2555 Telegraph Road, Bloomfield Hills, MI 48302 and must comply with the procedures outlined immediately below. The Committee’s evaluation of stockholder nominated candidates will be the same as for any other candidates.

      Stockholders who wish to recommend individuals for consideration by the Committee to become nominees for election to the Board may do so by submitting a written submission to the Corporate Secretary. Submissions must include sufficient biographical information concerning the recommended individual, including age, five-year employment history with employer names and a description of the employer’s business, whether such individual can read and understand basic financial statements and a list of board memberships (if any), of the nominee. The submission must be accompanied by a written consent of the individual to stand for election and serve if elected by the stockholders, a statement of any relationships between the person recommended and the person submitting the recommendation, and a statement of any relationships between the candidate and any automotive retailer, manufacturer or supplier. Recommendations received by September 30, 2004, will be considered for nomination at the 2005 annual meeting of stockholders. Recommendations received after September 30, 2004, will be considered for nomination at the 2006 annual meeting of stockholders.

      Director Compensation. We have established a Non-Employee Director Compensation Plan to compensate our directors who are not our paid employees, who we call “Outside Directors.” Pursuant to the Non-Employee Director Compensation Plan, each Outside Director receives an annual retainer of $40,000. These fees are payable, at the option of each Outside Director, in cash or in common stock at the current market price. The payment of fees may be deferred in either the form of cash and /or deferred stock units. Each stock unit is equal in value to a share of common stock and ultimately paid in cash. These stock units generate dividend equivalents in the form of additional stock units and are credited to the director’s account on the date the dividends are paid. Any fees deferred in cash will be held in the general funds of the Company. Interest on deferred fees is credited quarterly to the account at the then current U.S. 90-day Treasury Bill rate. In general, deferred amounts are not paid until after the director retires.

      Beginning in 2004, our Outside Directors also receive an annual grant of 1,000 shares of restricted stock generally in the first quarter. These restricted shares are on the same terms as those granted to employees and vest ratably and annually over three years. Each Outside Director is also entitled to the use of one of our vehicles. All directors are entitled to reimbursement for their reasonable out-of-pocket expenses in connection with their travel to, and attendance at, meetings of the Board of Directors or its committees. As of

Table of Contents

December 31, 2003, we had nine Outside Directors and three employee directors. In accordance with the internal policies of their employers, some of our directors assign their director compensation to the organizations that employ them or they waive the payment of the fee entirely. Directors who are also our or our subsidiaries’ employees receive no cash compensation for serving as directors or as members of committees. In May 2003, Roger Penske, Samuel DiFeo and Laurence Vaughan were granted 12,500 and 7,500 and 3,000 shares of restricted common stock in their capacity as company officers.

      Compensation Committee Interlocks and Insider Participation. During 2003, the Compensation and Management Development Committee was comprised of Lucio A. Noto (Chairman), H. Brian Thompson and Motokazu Yoshida. Mr. Penske is the Chairman of our Board of Directors and Chief Executive Officer. Mr. Penske is also the Chairman of the Board, Chief Executive Officer and a member of the compensation committee of Penske Corporation. Mr. Penske is also a managing member of Penske Capital Partners. See the section entitled “Related Party Transactions” for descriptions of further transactions involving Penske Capital Partners, Penske Corporation and Mr. Penske.

      In April 2003, an entity controlled by one of our directors, Lucio A. Noto (the “Investor”), paid approximately $1.8 million (including approximately $0.8 million credited from prior earnings retroactive to March 1, 2001) for a 6.5% interest in one of our subsidiaries, UAG Connecticut I, LLC, which entitles the Investor to 20% of the operating profits of UAG Connecticut I. From time to time, we provide UAG Connecticut I with working capital and other debt financing and make periodic pro rata distributions from UAG Connecticut I to the Investor, which in 2003 totaled $0.3 million. In addition, the Investor has an option to purchase up to a 20% interest in UAG Connecticut I for specified amounts. The Investor has also guaranteed 20% of UAG Connecticut I’s lease obligation to AGR, our landlord of the facility at which the dealership operates. In exchange for that guarantee, the Investor will be entitled to 20% of any appreciation of the property, which appreciation would otherwise accrue to AGR at the time of sale, and the Investor is responsible to AGR for any corresponding depreciation of the property at the time of sale, which obligation shall be secured solely by the Investor’s ownership interest in UAG Connecticut I, LLC.

PROPOSAL 3 — ELECTION OF DIRECTORS (IN THE ALTERNATIVE TO PROPOSAL 2)

      Stockholders will be asked to vote on this Proposal 3 solely in the event that at the annual meeting the stockholders do not approve the amendments to our certificate of incorporation and bylaws to eliminate our classified Board of Directors as described in Proposal 1. If the stockholders approve Proposal 1, then we will amend our certificate of incorporation and bylaws to eliminate our classified Board of Directors, and the stockholders will proceed to vote on Proposal 2 and not this Proposal 3. If, however, the stockholders do not approve Proposal 1, a vote will be taken on this Proposal 3.

      If the stockholders do not approve Proposal 1, each of the following are nominated for election to serve a three-year term and will be subject to re-election at the 2007 annual meeting: Michael R. Eisenson, Hiroshi Ishikawa, William J. Lovejoy and H. Brian Thompson.

      Pursuant to a stockholders agreement, certain of our stockholders affiliated with Roger S. Penske and Mitsui & Co., Ltd. have agreed to vote together to elect members to our Board of Directors. See “Related Party Transactions” for a description of the stockholders agreement.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” MICHAEL EISENSON,

HIROSHI ISHIKAWA, WILLIAM LOVEJOY AND H. BRIAN THOMPSON.

PROPOSAL 4 — APPROVAL OF THE UNITED AUTO GROUP, INC. MANAGEMENT

INCENTIVE PLAN

      Our Board of Directors has approved a bonus plan for our executive officers designed to provide for the payment of performance-based compensation that is qualified within the meaning of Section 162(m) of the Internal Revenue Code. The Board of Directors has approved this plan subject to the requisite approval by our stockholders.

Table of Contents

      The purpose of the United Auto Group, Inc. Management Incentive Plan (the “Plan”) is to better align the interests of our management with the interests of our stockholders by encouraging management to achieve goals designed to increase stockholder value. The full text of the Plan is set forth as Annex B to this proxy statement, and you should refer to it for a complete description of the Plan. The following summary of the key terms of the Plan is qualified by reference to the Plan. If the requisite stockholder approval is obtained, the Plan would be effective as of July 1, 2003.

      Intended Tax Treatment of Awards under the Plan. The Plan is designed to provide for the payment of performance-based compensation that is qualified within the meaning of Section 162(m) of the Internal Revenue Code and related Internal Revenue Service regulations and that we may deduct for tax purposes. Section 162(m) requires that certain material terms of a compensation plan, including participant eligibility, the business criteria on which performance goals are based and maximum award amounts, be approved by a company’s stockholders in order for compensation paid thereunder to be tax deductible. Accordingly, we are submitting the Plan for the requisite approval by our stockholders.

      Administration of the Plan. The Compensation and Management Development Committee of our Board of Directors, or such other committee or subcommittee as may be designated by our Board, will administer the Plan (the “Committee”). The Committee shall be comprised of two or more “outside directors” within the meaning of Section 162(m).

      Selection of Participants. The Committee, in its sole discretion, shall determine which of our executive officers or other key employees shall participate in the Plan in any particular year. An executive officer or key employee who is a participant for a given plan year is not guaranteed or assured of being selected for participation in any subsequent plan year.

      Establishment of Performance Targets. The Committee is responsible for identifying annual performance factors and establishing specific performance targets with respect thereto that must be met in order for bonuses to be paid under the Plan. The Committee has the sole discretion to determine whether, or to what extent, the established performance targets are achieved. Performance Targets may be described in terms of Company-wide objectives or objectives that are related to the performance of the individual participant or a subsidiary, division, region, product line, department or function. The performance targets may be based upon any or all of the following performance factors or any combination thereof: (i) net income; (ii) return on equity; (iii) earnings per share and other earnings measurements; (iv) return on assets and similar measurements; (v) gross profit and operating profit; (vi) earnings before interest and taxes; (vii) sales; (viii) gross margin; (ix) cost reduction goals; (x) fixed cost coverage measurements; (xi) share price performance metrics; (xii) cash flow; (xiii) balance sheet measurements; (xiv) human resource measurements; (xv) unit sales; (xvi) same-store sales; (xvii) customer satisfaction; and (xviii) productivity.

      The performance targets must be established while the performance relative to the established target remains substantially uncertain within the meaning of Section 162(m). Concurrently with the selection of performance factors and the establishment of targets relating thereto, the Committee must establish an objective formula or standard for calculating the maximum bonus payable to each participant. Subject to the discretion of the Committee, the performance measurement periods will typically be the one-year periods commencing on January 1.

      As provided in the definition of “Performance Objectives” in Section 2 of the Plan, if the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company, or the manner in which it conducts its business, or other events or circumstances render the performance targets unsuitable, the Committee may modify such performance targets or the related minimum acceptable level of achievement in whole or in part, as the Committee deems appropriate and equitable.

      Awards under the Plan. Awards under the Plan will be payable in cash or stock as determined by the Committee. Under the Plan, the maximum cash value of any bonus for each fiscal year may not exceed $5 million for any particular participant. Even if the Performance Factors are met, the Committee has sole discretion, pursuant to the exercise of its “negative discretion,” to decrease the amount of any award payable or to pay no award at all. In no event may the Committee increase at its discretion the amount of an award

payable upon attainment of the Performance Factors. Payment of any bonus under the Plan may be deferred, subject to the Plan’s terms and any other written commitment authorized by the Committee.

Employment Contracts

      We entered into a letter agreement with Samuel DiFeo in August 1999. Pursuant to this agreement, Mr. DiFeo agreed to serve as our President through December 31, 1999, subject to our right to extend his service as President through December 31, 2000, at a salary of at least $0.5 million per year. If Mr. DiFeo’s employment is terminated as a result of death, Mr. DiFeo’s estate is entitled to receive, among other things, a cash payment of $0.8 million. In addition, we agreed to retain Mr. DiFeo as a consultant after the letter agreement expires. The consulting agreement is to continue for a period of 48 months and may be extended for an additional year at our option. It provides for compensation of $0.4 million per year, plus use of an automobile, reimbursement of expenses and other health benefits. The agreement prohibits Mr. DiFeo from seeking or obtaining employment in the automotive industry while the consulting agreement is in effect.

      We are not a party to employment contracts with the remaining named executive officers.

REPORT OF THE COMPENSATION AND MANAGEMENT

DEVELOPMENT COMMITTEE ON EXECUTIVE COMPENSATION

      Our Compensation and Management Development Committee’s responsibilities include establishing our policies regarding the compensation of our executive officers and other key employees. The Compensation and Management Development Committee approves all elements of compensation for our executive officers and is responsible for the administration of our incentive plans.

      Executive Compensation. Our compensation program consists of base salary, annual incentive payments, equity-based awards and employee health and other benefits, such as the use of a company vehicle. The goal of our compensation program is to motivate and reward our executive officers and other key employees to improve long-term stockholder value and to attract and retain the highest quality executive and key employee talent available. Our executive compensation program is designed to align executive compensation practices with increasing the value of our common stock and to foster adherence to, and promotion of, our business mission, values, strategic goals and annual objectives.

      Our Compensation and Management Development Committee reviews and counsels with management relative to the appropriate compensation for management given their role in the corporate structure. It reviews salary levels as well as salary increases for the current year in order to maintain internal compensation consistency and external compensation competitiveness. It reviews and recommends incentive payments to be made in connection with the previous year’s performance considering the executive’s scope of responsibilities, level of experience, individual performance and attainment of pre-established goals, as well as our business plan and general economic factors. In making its decisions the Committee receives input from our Chief Executive Officer and President to assure congruity with our long-term performance goals.

13


Table of Contents

      Base Salary and Bonus. The salary levels for our officers are determined by level of job responsibility and experience, job performance and attainment of pre-established goals. Bonus payouts to our executive officers and other key employees are influenced by the attainment of corporate earnings goals.

      Equity Incentives. Our Compensation and Management Development Committee believes strongly that the interests of senior management must be closely aligned with those of our stockholders. Prior to 2003, we granted management equity compensation in the form of stock options. Having considered much of the recent commentary concerning the use of stock options, beginning in 2003, we only issued equity compensation to our senior management team in the form of restricted stock. We believe that long-term incentives in the form of restricted stock or similar equity-based compensation more closely align the incentives for management with the interests of our stockholders.

      We grant restricted stock on a discretionary basis within a guideline range that takes into account the position responsibilities of executive officers and key employees whose contributions and skills are important to our long-term success. The restricted stock granted to date has had a three year annual and ratable vesting period. During 2003, the Committee granted 329,195 shares of restricted stock to our executive officers or key employees, some of which has reverted back to us as employees have departed from the Company.

      Management Incentive Plan. Section 162(m) of the Internal Revenue Code of 1986, as amended, generally imposes a $1,000,000 per taxable year ceiling on tax-deductible remuneration paid to any one of the five most highly compensated executive officers of a publicly-held corporation, unless the remuneration is treated as performance based or is otherwise exempt from the provisions of Section 162(m). In 2003, the Committee adopted the United Auto Group Management Incentive Plan, designed to provide for the payment of performance-based compensation that is qualified within the meaning of Section 162(m) of the Internal Revenue Code and that we may deduct for tax purposes. Section 162(m) requires that certain material terms of a compensation plan, including participant eligibility, the business criteria on which performance goals are based and maximum award amounts, be approved by a company’s stockholders in order for compensation paid thereunder to be tax deductible. Accordingly, we are submitting the Management Incentive Plan for the requisite approval by our stockholders at the annual meeting. If approval is obtained, we expect to award performance compensation to certain members of our management team in the future.

      While the Compensation and Management Development Committee intends to maximize the tax-efficiency of its compensation programs generally, it retains the flexibility in its membership and in the manner in which it awards compensation to act in the best interests of the Company and its stockholders, including awarding compensation which may not be deductible by reason of Section 162(m).

      Chief Executive Officer. For 2003, our Compensation and Management Development Committee awarded Mr. Penske a bonus of $1.0 million. The bonus was based on our strong financial performance as well as operational performance such as achievements in customer satisfaction. In 2003, we substantially increased our gross revenues and net income from 2002 levels. We successfully accomplished our targeted level of acquisitions and made significant strides toward integrating those operations into our business. We also continued to be the industry leader in same-store sales.

      In determining the compensation of Mr. Penske, the Committee also monitors the compensation of the Company’s peers. While the Committee believes that the Company’s successes noted above are in large part due to the contributions of Mr. Penske, it has noted that Mr Penske’s compensation is generally on par or less than those of our peer companies’ chief executive officers. Mr. Penske does not participate in the approval of his own compensation.

AUDIT COMMITTEE REPORT

      The Audit Committee of the Board of Directors is responsible for providing independent, objective oversight of our accounting functions and internal controls. The Audit Committee acts under a written charter adopted and approved by the Board of Directors. Each of the members of the Audit Committee is independent, as defined by the New York Stock Exchange rules and applicable law.

      The responsibilities of the Audit Committee include recommending to the Board of Directors an accounting firm to be engaged as our independent accountants. In accordance with the Audit Committee charter, the Audit Committee has the sole authority to retain and terminate our independent accountants. The Audit Committee is responsible for recommending to the Board of Directors that our financial statements be included in our Annual Report on Form 10-K. The Audit Committee took a number of steps in making this recommendation for 2003. First, the Audit Committee discussed with Deloitte & Touche those matters required to be discussed by Statement on Auditing Standards No. 61, including information regarding the scope and results of the audit. These communications and discussions are intended to assist the Audit Committee in overseeing the financial reporting and disclosure process.

Table of Contents

      Second, the Audit Committee discussed with Deloitte & Touche their independence and received from Deloitte & Touche a letter concerning independence as required under applicable independence standards for auditors of public companies. This discussion and disclosure assisted the Audit Committee in evaluating such independence. Finally, the Audit Committee reviewed and discussed the annual audited and quarterly unaudited financial statements with our management and Deloitte & Touche in advance of public release of operating results, and filing of annual and quarterly reports with the Securities and Exchange Commission.

      Based on the discussions with Deloitte & Touche concerning the audit, and their independence, and the financial statement review, and such other matters deemed relevant and appropriate by the Audit Committee, the Audit Committee recommended to the Board of Directors that our financial statements be included in our 2003 Annual Report on Form 10-K.

INDEPENDENT ACCOUNTANTS

      Deloitte & Touche LLP, the member firms of Deloitte Touche Tohmutsu, and their respective affiliates (collectively, the “Deloitte Entities”) will audit our consolidated financial statements for 2004 and perform other services. We paid the Deloitte Entities the following fees for the enumerated services in 2003, all of which services were approved by our Audit Committee.

      Audit Fees. The aggregate fees for professional services rendered by the Deloitte Entities in connection with their audit of our consolidated financial statements, reviews of the consolidated condensed financial statements included in our quarterly reports on Form 10-Q and other services normally provided in connection with statutory or regulatory engagements for 2003 and 2002, were approximately $840,000 and $997,000, respectively.

      Audit Related Fees. The aggregate fees for professional services rendered by the Deloitte Entities in connection with their assurance services related to benefit plans and accounting research and consultation in 2003 and 2002 were approximately $44,000 and $35,000, respectively.

      Tax Fees. The aggregate fees for professional services rendered by Deloitte & Touche in connection with tax compliance, planning and advice in 2003 and 2002 were approximately $341,000 and $850,000, respectively, of which approximately $110,000 related to tax compliance in both years.

      All Other Fees. The aggregate fees for all other services rendered by Deloitte & Touche LLP in Fiscal 2003 and 2002 were approximately $50,000 and $315,000, respectively. These fees related primarily to a review of certain operational processes at our dealerships.

      The Audit Committee has considered the nature of the above-listed services provided by Deloitte & Touche LLP and determined that they are compatible with their provision of independent audit services. The Audit Committee has discussed these services with Deloitte & Touche and management to determine that they are permitted under the Code of Professional Conduct of the American Institute of Certified Public Accountants and the auditor independence requirements of the Securities and Exchange Commission.

      Pre-approval Policy. The Audit Committee has adopted a policy requiring pre-approval of audit and non-audit services provided by the independent auditors. The primary purpose of this policy is to ensure that we engage our public accountants to only provide audit and non-audit services that are compatible with maintaining independence. The Audit Committee is required to pre-approve all services performed for us by our independent auditors and the related fees for such services. The Audit Committee must also approve fees incurred for pre-approved services that are in excess of the approved amount prior to payment, except as provided below. The Company’s independent auditors are prohibited from performing any service prohibited by applicable law.

18


Table of Contents

      Pre-approval of audit and non-audit services may be given at any time up to a year before commencement of the specified service. Engagement of the independent auditors and their fees for the annual audit must be approved by the entire Committee. The Chairman of the Audit Committee may independently approve services if the estimated fee for the service is less than 10% of the total estimated audit fee, or if the excess fees for pre-approved services are less than 20% of the approved fees for that service; provided, however, that no such pre-approval may be granted with respect to any service prohibited by applicable law or that otherwise appears reasonably likely to compromise the independent auditor’s independence. Any pre-approval granted pursuant to this delegation of authority will be reviewed with the Audit Committee at its next regularly scheduled meeting. Non-audit services for which the estimated fee is greater than 10% of the audit fee must be approved by the entire Committee before commencement of the service.

      A representative of Deloitte & Touche LLP will be present at the annual meeting with the opportunity to make a statement and to answer questions.

RELATED PARTY TRANSACTIONS

      Entities affiliated with Roger S. Penske, our Chairman of the Board and Chief Executive Officer, are parties to a stockholders agreement described below. Mr. Penske is also Chairman of the Board and Chief Executive Officer of Penske Corporation, and, through entities affiliated with Penske Corporation, our largest stockholder. The parties to the stockholders agreement are International Motor Cars Group, I., L.L.C. (“IMCGI”), International Motor Cars Group, II, L.L.C. (“IMCGII”), Mitsui & Co., Ltd., Mitsui & Co, (USA), Inc. (collectively, “Mitsui”), Penske Corporation and Penske Automotive Holdings Corp. We refer to IMCGI, IMCGII, Penske Corporation and Penske Automotive Holdings Corp. as the Penske affiliated companies.

      In March 2004, we issued and sold 4,050,000 shares of our common stock to Mitsui in exchange for $119 million under the terms of a purchase agreement between us, Mitsui and the Penske affiliated companies. This purchase agreement also contains other agreements between the parties. The Penske affiliated companies and Mitsui have agreed to certain “standstill” provisions. Until termination of the stockholders agreement discussed below, among other things and with some exceptions, the parties have agreed not to acquire or seek to acquire any of our capital stock or assets, enter into or propose business combinations involving us, participate in a proxy contest with respect to us or initiate or propose any stockholder proposals with respect to us. Notwithstanding the prior sentence, the purchase agreement permits (1) any transaction approved by either a majority of disinterested members of the Board of Directors or a majority of the disinterested stockholders, (2) in the case of Mitsui, the acquisition of securities if, after giving effect to such acquisition, the beneficial ownership in us is less than or equal to 49%, (3) in the case of the Penske affiliated companies, the acquisition of securities if, after giving effect to such acquisition, the beneficial ownership in us is less than or equal to 65%, and (4) the acquisition of securities resulting from equity grants by the Board of Directors to individuals for compensatory purposes.

      We have also agreed to grant Mitsui the right to an observer to our Board of Directors as long as they own at least 2.5% of our outstanding common stock, and the right to have an appointee designated as a senior vice president of the Company, as long as they own at least 10% of our outstanding common stock. We also agreed not to take any action that would restrict the ability of a stockholder to propose, nominate or vote for any person as a director of us, subject to certain limitations.

      Simultaneously with this purchase, Mitsui and the Penske affiliated companies entered into a stockholders agreement. Under this stockholders agreement, the Penske affiliated companies agreed to vote their shares for one director who is a representative of Mitsui. In turn, Mitsui agreed to vote their shares for up to fourteen directors voted for by the Penske affiliated companies. In addition, the Penske affiliated companies agreed that if they transfer any of our shares of common stock, Mitsui would be entitled to “tag along” by transferring a pro rata amount of their shares upon similar terms and conditions, subject to certain limitations. This agreement terminates on its tenth anniversary, upon the mutual consent of the parties or when either party no longer owns any of our common stock.

      Registration Rights Agreements. In May 1999, we and IMCGI and IMCGII entered into a registration rights agreement and in December 2000, we and Penske Automotive Holdings Corp. entered into a registration rights agreement. Pursuant to these agreements, IMCGI and IMCGII and Penske Corporation each may require us on three occasions to register all or part of their common stock, subject to specified limitations. They are also entitled to request inclusion of all or any part of their common stock in any registration of securities by us on Forms S-1, S-2 and S-3 under the Securities Act.

      In connection with the purchase of shares discussed above, in March 2004, we entered into a registration rights agreement with Mitsui. Under this agreement, Mitsui may require us on two occasions to register all or part of their common stock, subject to specified limitations. Mitsui also is entitled to request inclusion of all or any part of their common stock in any registration of securities by us on Forms S-1, S-2 and S-3 under the Securities Act. We have agreed to pay all expenses (subject to some limitations) incident to the registration and disposition of the securities registered pursuant to all of these registration rights agreements (other than underwriting discounts and commissions in respect thereof).

      Prior Stockholders Agreement. In March 2004, we terminated a stockholders agreement between us, the Penske affiliated companies and Mitsui. The rights and obligations under this agreement have terminated. Pursuant to that now-terminated agreement, the parties agreed to vote their shares of common stock to elect Roger S. Penske, four additional persons nominated by some of the Penske affiliated companies, one person nominated by Mitsui and three independent persons as our directors. The Penske entities only nominated three members to the Board of Directors under this agreement (Richard J. Peters, James A. Hislop and Eustace W. Mita) even though they were entitled to four nominees. Motokazu Yoshida was the nominee to the Board of Directors by Mitsui. The parties also agreed to use their reasonable best efforts to have our compensation committee of the Board of Directors consist of Roger S. Penske, one additional designee of the Penske entities and two independent directors. The Penske entities did not designate a member of the compensation committee and Mr. Penske did not serve on the compensation committee.

      Other Related Party Interests. James A. Hislop, one of our directors, is the President, Chief Executive Officer and a managing member of Penske Capital Partners (who is the managing member of IMCGI and IMCGII), a director of Penske Corporation and a managing director of Transportation Resource Partners, an organization affiliated with Roger S. Penske which undertakes investments in transportation related industries. Mr. Penske also is a managing member of Penske Capital Partners. Richard J. Peters, one of our directors, is a director of Penske Corporation and a managing director of Transportation Resource Partners. Eustace W. Mita is an investor in Transportation Resources Partners. Robert H. Kurnick, Jr., our Executive Vice President and General Counsel, is also the President and a director of the Penske Corporation and Paul F. Walters, our Executive Vice President — Human Resources serves in a similar human resources capacity for Penske Corporation.

      CarsDirect.com. In May 2000, we, along with Penske Automotive Group, Inc. (PAG), an automobile dealership company controlled by Roger S. Penske, entered into an operating agreement with CarsDirect.com, Inc. whereby PAG and we supply vehicles to CarsDirect.com at pre-negotiated prices through PAG’s and our respective franchised vehicle dealers. During the term of the operating agreement, CarsDirect.com will offer the franchised vehicle dealers of PAG or the Company with the closest geographic proximity to the customer the first opportunity to supply the vehicle purchased through their website. As consideration for entering into the operating agreement, CarsDirect.com granted to PAG and us warrants to purchase 3,650,000 shares of Series D Preferred Stock of CarsDirect.com at a per share purchase price of $15.76, which vest and become exercisable annually based upon certain sales milestones under the operating agreement. We and PAG have agreed to allocate the warrants after they vest in proportion to our relative sales to CarsDirect.com under the operating agreement.

      Other Transactions. From time to time, we pay and/or receive fees from Penske Corporation and its affiliates for services rendered in the normal course of business, including rents paid to Automotive Group Realty, LLC (“AGR”), as described below, payments to third parties made by Penske Corporation on behalf of us, for which we then reimburse Penske Corporation, payments relating to the use of aircraft from Penske Aviation Services, and payment of a racing sponsorship to Penske Racing. These transactions reflect the

20


Table of Contents

provider’s cost or an amount mutually agreed upon by both parties. We believe that the payments relating to these transactions are on terms at least as favorable as those that could be obtained from an unaffiliated third party negotiated on an arm’s length basis. Aggregate payments relating to such transactions amounted to $9.7 million in 2003, excluding the payments to AGR discussed below.

      We are currently a tenant under a number of non-cancelable lease agreements with Samuel X. DiFeo and members of his family. Mr. DiFeo is our President and Chief Operating Officer and one of our directors. During 2003, we paid $5.5 million to Mr. DiFeo and his family under these lease agreements. We believe that the terms of these transactions are at least as favorable as those that could be obtained from an unaffiliated third party negotiated on an arm’s length basis.

      We are currently a tenant under a number of non-cancelable lease agreements with AGR. AGR is a wholly-owned subsidiary of Penske Corporation. During 2003, we paid $5.9 million to AGR under these lease agreements. In addition, in 2003 we sold AGR real property and improvements for $19.3 million which were subsequently leased by AGR to us. The sale of each parcel of property was valued at a price which was either independently confirmed by a third party appraiser or at the price for which we purchased the property from an independent third party. We believe that the terms of these transactions are at least as favorable as those that could be obtained from an unaffiliated third party negotiated on an arm’s length basis.

      We are also party to operating agreements with Roger S. Penske, Jr., the son of Roger S. Penske, reflecting (1) the 2001 purchase by Mr. Penske, Jr. of 10% of one of our subsidiaries, HBL, LLC, and (2) the 2000 purchase by Mr. Penske, Jr. of 4.7% of one of our subsidiaries, United Auto do Brasil, Ltda., of which we own 90.6%. From time to time, we provide these subsidiaries with working capital and other debt financing and make periodic pro rata distributions from these subsidiaries to Mr. Penske, Jr., which in 2003 totaled seven hundred thousand dollars. For 2003, Mr. Penske, Jr., received total compensation from us of one million nine hundred ninety thousand dollars in his capacity as our Regional President and as of July 2003 Executive Vice President – Eastern Operations.

      In 2003, we employed the sons of Eustace Mita, one of our directors, and James Davidson, our Executive Vice President — Finance, at one of our dealerships as sales managers for which each was compensated in excess of $60,000. We employ the son-in-law of Paul Walters, our Executive Vice President, Human Resources, as Senior Vice President Manufacturer Relations for which he received compensation in excess of $60,000 in 2003.

      In April 2003, an entity controlled by one of our directors, Lucio A. Noto (the “Investor”), paid approximately $1.8 million (including approximately $0.8 million credited from prior earnings retroactive to March 1, 2001) for a 6.5% interest in one of our subsidiaries, UAG Connecticut I, LLC, which entitles the Investor to 20% of the operating profits of UAG Connecticut I. From time to time, we provide UAG Connecticut I with working capital and other debt financing and make periodic pro rata distributions from UAG Connecticut I to the Investor, which in 2003 totaled $0.3 million. In addition, the Investor has an option to purchase up to a 20% interest in UAG Connecticut I for specified amounts. The Investor has also guaranteed 20% of UAG Connecticut I’s lease obligation to AGR, our landlord of the facility at which the dealership operates. In exchange for that guarantee, the Investor will be entitled to 20% of any appreciation of the property, which appreciation would otherwise accrue to AGR at the time of sale, and the Investor is responsible to AGR for any corresponding depreciation of the property at the time of sale, which obligation shall be secured solely by the Investor’s ownership interest in UAG Connecticut I, LLC.

Any Performance Objectives applicable to a Qualified Performance-Based Award shall be limited to specified levels of or increases or decreases in return on equity, earnings per share, total earnings, earnings growth, earnings from continuing operations, return on capital, return on assets, gross profit, earnings before interest and taxes, sales, sales growth, gross margin, cost reduction goals, fixed cost coverage measurements (including, but not limited to, the ratio of service and parts revenues to operating costs), return on investment, increase in the fair market value of the Common Stock, share price (including, but not limited to, growth measures and total stockholder return), market capitalization, operating profit, net income, cash flow (including, but not limited to, operating cash flow and free cash flow), financial return ratios, total return to shareholders, market share, earnings measures /ratios, balance sheet measurements (including, but not limited to, debt to equity ratios and inventory or receivable turnover), human resources measurements (including, but not limited to, measurements of employee

  turnover, workers’ compensation costs and employee satisfaction), internal rate of return, unit sales, same store sales, customer satisfaction and productivity. If the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company, or the manner in which it conducts its business, or other events or circumstances render the Performance Objectives unsuitable, the Committee may modify such Performance Objectives or the related minimum acceptable level of achievement, in whole or in part, as the Committee deems appropriate and equitable; provided however that in the case of a Qualified Performance-Based Award, such modification is only permitted to the extent prescribed by Section 162(m) of the Code and the Regulations.

  (k)  “Performance Period” means a period determined by the Committee which shall be used for purposes of determining whether Awards are earned by Participants.

  (l)  “Performance Target” means a target level of performance, based on one or more           Performance Objectives, established for a Performance Period in accordance with Section 4.

  (m)  “Plan” means the United Auto Group, Inc. Management Incentive Plan, as stated herein, and as amended from time to time.

  (n)  “Qualified Performance-Based Award” means an Award or portion of an Award to an Officer that is intended to satisfy the requirements for “qualified performance-based compensation” under Code Section 162(m). The Committee shall designate any Qualified Performance-Based Award as such at the time of grant.
 
  (o)  “Regulations” means the Treasury Regulations promulgated under the Code, as amended from time to time.
 
  (p)  “Retirement” means termination of employment with the Company or a Subsidiary after completing at least 5 years of continuous employment and attaining age 60.
 
  (q)  “Subsidiary” means a corporation or other entity (i) more than fifty percent (50%) of whose outstanding shares or securities (representing the right to vote for the election of directors or other managing authority) are, or (ii) which does not have outstanding shares or securities (as may be the case in a Partnership, joint venture or unincorporated association), but more than fifty percent (50%) of whose ownership interest (representing the right generally to make decisions for such other entity) is, now or hereafter owned or controlled directly or indirectly by the Company.

      2. PARTICIPATION. For each Performance Period, the Committee shall designate those key employees of the Company and its Subsidiaries who shall receive Awards under the Plan. Selection for participation for one Performance Period shall not confer on a Participant the right to participate in the Plan for any other Performance Period.

      3. AWARDS. For each Performance Period, each Participant shall receive an Award entitling the Participant to receive cash incentive compensation or other incentive compensation (including common stock or other awards under the United Auto Group, Inc. 2002 Equity Plan (or similar plan)) upon the attainment of one or more Performance Targets. The Committee may establish different terms for Awards for different Participants or groups of Participants. The amount of compensation payable under an Award may be stated as a dollar amount or as a percentage of the Participant’s base compensation. The Committee may provide for a threshold level of performance below which no amount of compensation will be paid and a maximum level of performance above which no additional amount of compensation will be paid, and it may provide for the payment of differing amounts of compensation for different levels of performance. Notwithstanding any other provision of the plan to the contrary, the Committee retains the absolute discretion to reduce the amount of any incentive compensation that would be otherwise payable to a participant (including a reduction in such amount to zero).

      4. ESTABLISHMENT OF PERFORMANCE TARGETS. Within the first twenty-five percent (25%) of each Performance Period, the Committee shall establish one or more Performance Targets for that Performance Period.

B-2

      5. PAYMENT OF AWARDS. Within ninety (90) days following the end of each Performance Period, the Committee shall determine whether the Performance Targets for such Performance Period have been satisfied and shall certify its determination in approved minutes of the Committee meeting held for such purpose. If the Committee certifies that one or more Performance Targets for a Performance Period have been achieved, all compensation payable in respect of Awards subject to such Performance Target shall be paid to Participants as soon as reasonably practicable thereafter (subject to the limitations set forth in paragraph 3); provided, however, that the Committee may permit the deferral of such compensation under a deferred compensation plan of the Company or a Subsidiary. If a Performance Target for a Performance Period is not achieved, the Committee in its sole discretion may determine that all or a portion of any Award shall be deemed to be earned based on such criteria as the Committee deems appropriate, including without limitation individual performance or the performance of the Subsidiary or business division employing the Participant; provided, however, that the Committee shall not have such discretion with respect to any Qualified Performance-Based Award. Any Award that is not considered earned in accordance with this Section shall be forfeited.

      6. PARTIAL PARTICIPATION. Unless the Committee shall determine otherwise, the rules and procedures for partial participation shall be consistent with the following:

  (a)  EMPLOYMENT TERMINATION. If a Participant terminates employment with the Company before payment of Awards are made for a Performance Period for reasons other than death, disability or Retirement, any Award granted to the Participant in respect of that Performance Period shall be forfeited and cancelled.
 
  (b)  DEATH, DISABILITY OR RETIREMENT. A Participant whose employment terminates during a Performance Period because of death, disability or Retirement may, under such rules as the Committee may from time to time prescribe, be eligible for consideration for a pro-rata Award based on the period of active employment during the Performance Period.
 
  (c)  LEAVE OF ABSENCE. A Participant who is on a leave of absence other than a personal leave for more than ninety (90) consecutive days during the Performance Period, or who is on a personal leave of absence for more than thirty (30) consecutive days, shall forfeit any portion of an Award attributable to said period of leave pursuant to such rules as the Committee may establish.

      7. MAXIMUM AMOUNT OF QUALIFIED PERFORMANCE-BASED AWARDS. The maximum dollar amount of compensation that may be paid to any Participant in respect of Qualified Performance-Based Awards for a single fiscal year shall be $5,000,000.

      8. ADJUSTMENTS. To the extent that a Performance Target is based on an increase in the Fair Market Value of the Common Stock, in the event of any stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of the Company, any merger, consolidation, spin-off, reorganization, partial or complete liquidation or other distribution of assets (other than a normal cash dividend), issuance of rights or warrants to purchase securities or any other corporate transaction having an effect similar to any of the foregoing, then the Committee may make or provide for such adjustments in such Performance Target as the Committee in its sole discretion may in good faith determine to be equitably required in order to prevent dilution or enlargement of the rights of Participants.

      9. TAX WITHHOLDING. The Company shall be entitled to withhold from any payment made under the Plan the full amount of any required federal, state or local taxes.

      10. NONTRANSFERABILITY OF BENEFITS. A Participant may not assign or transfer any interest in an Award. Notwithstanding the foregoing, upon the death of a Participant, the Participant’s rights and benefits under the Plan shall pass by will or by the laws of descent and distribution.

      11. ADMINISTRATION AND INTERPRETATION. The Committee shall have complete authority to interpret the Plan, to prescribe rules and requirements relating to it, and to make all determinations necessary or advisable in the administration of the Plan, including, without limitation, the amending or

B-3

altering of the Plan as may be required to comply with or conform to any federal, state or local laws or regulations.

      12. AMENDMENT AND TERMINATION OF PLAN. The Committee may at any time terminate the Plan and may at any time and from time to time amend or modify the Plan in any respect; provided, however, that no amendment shall be effective without approval of the stockholders of the Company if the amendment would increase the maximum amount of compensation payable to a Participant in any Performance Period pursuant to Qualified Performance-Based Awards as specified in Section 7. Neither the termination of the Plan nor any amendment to the Plan shall reduce benefits accruing under Awards granted prior the date of such termination or amendment.

      13. GOVERNING LAW. The Plan shall be governed and construed in accordance with the laws of the State of Michigan. As a condition to eligibility to receive an Award under the Plan, each Participant irrevocably consents to the exclusive jurisdiction of the courts of the State of Michigan and of any federal court located in the Eastern District of Michigan in connection with any action or proceeding arising out of or relating to this Plan, any document or instrument delivered pursuant to or in connection with this Plan, or any alleged breach of this Plan or any such document or instrument.

      14. EFFECTIVE DATES AND STOCKHOLDER APPROVAL. This Plan shall be effective for periods beginning on and after July 1, 2003, provided that no Qualified Performance-Based Award shall be effective if the Plan is not approved by a vote of the stockholders of the Company at an annual meeting or special meeting.

      15. OFFSETS. As a condition to eligibility for an Award, each Participant consents to the deduction from the Award of any amounts owed by the Participant to the Company to the extent permitted by applicable law.

      16. NO RIGHTS TO CONTINUED EMPLOYMENT. Participation in the Plan does not create or constitute an express or implied employment contract between the Company and the Participant nor limit the right of the Company to discharge or otherwise deal with a Participant without regard to the existence of the Plan.

      17. UNFUNDED PLAN. The Plan shall at all times be an unfunded payroll practice and no provision shall at any time be made with respect to segregating assets of the Company for payment of any Award. No Participant or any other person shall have any interest in any particular assets of the Company by reason of the right to receive an Award under the Plan and any such Participant or any other person shall have only the rights of a general unsecured creditor of the Company.
