Report of the Compensation Committee of the Board of Directors The Compensation Committee ("Committee") of the Board of Directors of the Company currently consists of Hugh E. Bradley, Robert A. Peterson, and John S. Zink, all of whom are independent directors who are not employees and who qualify as non-employee directors for purposes of Rule 16b-3 adopted under the Securities Exchange Act of 1934. The Committee is responsible for evaluating the performance of the Chief Executive Officer and the Chief Financial Officer ("Named Executive Officers"), determining the compensation of the Named Executive Officers and administering the Company's stock option plan under which grants may be made to employees of the Company. The Committee has furnished the following report on executive compensation for the fiscal year ending May 31, 2000. The annual compensation package of the Named Executive Officers primarily consists of (i) a cash salary which reflects the responsibilities relating to the position and individual performance, (ii) variable performance awards payable in cash and tied to the individual's and the Company's performance against pre-established financial measures and (iii) long-term stock-based incentive awards which strengthen the relationship between the interests of the Named Executive Officers and the interests of the Company's stockholders. In determining the level and composition of compensation for each Named Executive Officer, the Committee takes into account various qualitative and quantitative indicators of each officer's performance. The Committee's objectives in determining compensation are to allow the Company to attract, motivate and retain the executive personnel necessary for the Company's success and to provide an executive compensation program comparable to that offered by the companies with which the Company competes for such management personnel. Although no specific target has been established, the Committee generally seeks to set salaries at or below the average of a range in comparison to peer group companies based upon experience of the Named Executive Officers. In setting salaries, the Compensation Committee considers its peer group to be certain companies with market capitalizations similar to that of the Company. This peer group does not necessarily include the companies comprising the Standard and Poor's Engineering and Construction Index reflected in the performance graph in this Proxy Statement, which is the industry categorization the Company has been placed in by its market makers. In evaluating the performance of the Named Executive Officers, the Committee takes into consideration such factors as total operating income (TOI) based on a fiscal budget plan which is reviewed by the Committee and economic value added (EVA) which takes into consideration how total assets and long-term debt are managed by the Named Executive Officers. Base compensation is established through negotiation between the Company and the Named Executive Officer at the time the executive is hired, or named to the executive position, and then subsequently (in general annually) when such officer's base compensation is subject to review or reconsideration. Base salaries after the initial year will be determined by the Compensation Committee after review of the officer's performance. In establishing or reviewing base compensation levels for each Named Executive Officer, the Committee, in accordance with its general compensation policy, considers numerous factors, including the responsibilities relating to the position, the qualifications of the executive and the relevant experience the individual brings to the Company, strategic goals for which the executive has responsibility, and compensation levels of other companies at a comparable stage of development to compete with the Company for business and executive talents. No predetermined weights are given to any such factors. The salaries for each of the Named Executive Officers in fiscal year 2000 were set taking into account these factors in accordance with the Company's general compensation policy discussed above.

In addition to each Named Executive Officer's base compensation, the Committee may award cash bonuses and/or grant awards under the Company's Stock Option Plan to Named Executive Officers depending on the extent to which certain defined personal and corporate performance goals are achieved. Such corporate performance goals include revenue and earnings targets of the Company, as discussed above. The Chief Executive Officer's compensation is the responsibility of the Compensation Committee. Based upon the Compensation Committee's assessment of Mr. Vetal's ability to effectively lead the Company into the future as determined by his past performance and experience with the Company's business and markets, the Compensation Committee determined that Mr. Vetal's compensation package would consist of the following: (i) annual base salary of $215,402 and (ii) annual bonus target of 70% of annual salary based upon the Company achieving specific TOI and EVA targets as discussed above. For the past year, the Chief Executive Officer's bonus resulted in a 42% of salary bonus with an achieved TOI of 93% of plan and an achieved EVA of 97% of plan. The Chief Financial Officer's compensation is the responsibility of the Compensation Committee. Based upon the Compensation Committee's assessment of Mr. Hall's ability to effectively lead the Company into the future as determined by his past performance and experience with the Company's business and markets, the Compensation Committee determined that Mr. Hall's compensation package would consist of the following: (i) annual base salary of $165,400 and (ii) annual bonus target of 50% of annual salary based upon the Company achieving specific TOI and EVA targets as discussed above. For the past year, the Chief Financial Officer's bonus resulted in a 30% of salary bonus with an achieved TOI of 93% of plan and an achieved EVA of 97% of plan. Equity incentives are not limited to executive officers. Grants of stock options are made to management and staff of the Company in amounts determined by the Compensation Committee. The amounts of such grants are determined based on the individual employee's position with the Company and his or her potential ability to beneficially impact the performance of the Company. By giving management and staff a stake in the financial performance of the Company, the Compensation Committee's goal is to provide incentives to these employees of the Company to enhance the financial performance of the Company and, thus, stockholder value. All salaried employees of the Company, including the Named Executive Officers, are eligible to receive long-term stock based incentive awards under the Company's Stock Option Plan as a means of providing such individuals with a continuing proprietary interest in the Company. Such grants further the mutual interests of the Company's employees and its stockholders by providing significant incentives for such employees to achieve and maintain high levels of performance. The Company's Stock Option Plan enhances the Company's ability to attract and retain the services of qualified individuals. Factors considered in determining whether such awards are granted includes the employee's position in the Company, his or her performance and responsibilities, the number of options, if any, currently held, and the vesting schedule of any such options. The Committee has adopted an established schedule for the issuance of options, with designated option grants for specific salary grades over a 3-year period. On January 3, 2000, the Compensation Committee approved severance agreements for both Mr. Vetal and Mr. Hall that would be triggered if a "change in control" in the ownership of the Company resulted in any "adverse personal action" against Mr. Vetal or Mr. Hall. Copies of these agreements are exhibits to the Company's annual report on Form 10-K. The report of the Compensation Committee shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent that the

Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under such acts. Members of the Compensation Committee Hugh E. Bradley Robert A. Peterson John S. Zink Report of the Audit Committee of the Board of Directors The Audit Committee has: o Reviewed and discussed the audited financial statements with management o Discussed with the independent auditors the matters required to be discussed by SAS 61. o Received the written disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1, and has discussed with the independent auditors the auditors' independence. o Based on the review and discussions above, 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 last fiscal year for filing with the Securities and Exchange Commission. The Board of Directors has determined that the members of the Audit Committee are independent. The Audit Committee has adopted a written charter. The charter is included as Exhibit A to this proxy statement. Members of the Audit Committee: Hugh E. Bradley Robert A. Peterson John S. Zink This report of the Audit Committee shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filling under the Securities Act of 1944, as amended, or under the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporated this information by reference, and shall not otherwise be deemed filed under such acts. Certain Transactions Mr. Robert Peterson, a director, is the Chief Executive Officer of Melton Truck Lines, Inc., a transportation company that has provided trucking services to Matrix Service Company. During fiscal year 2000, Melton Truck Lines, Inc. billed Matrix Service Company $314,152 and Matrix Service Company is current on its open account obligations, which are the same terms as all other Melton Truck Lines' customers.

Compliance with Section 16(a) Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company's directors and officers, and persons who own more than ten percent of the Common Stock, to file initial reports of ownership and reports of changes in ownership (Forms 3, 4 and 5) of the Common Stock with the Securities and Exchange Commission (the "SEC") and the NASDAQ Stock Market. Officers, directors and greater than 10 percent stockholders are required by SEC regulations to furnish the Company with copies of all such forms that they file. To the Company's knowledge, based solely on the Company's review of the copies of such reports received by the Company and on written representations by certain reporting persons, the Section 16(a) filing requirements were satisfied by the Company's directors, officers and ten percent stockholders. PROPOSAL NUMBER 2: To Increase Authorized Common Stock The Board of Directors of the Company has unanimously adopted resolutions approving, declaring advisable and recommending adoption by the stockholders of an amendment to the Company's Certificate of Incorporation to increase the authorized shares of the Company's Common Stock from 15,000,000 shares to 30,000,000 shares. As of September 5, 2000, the Company had 9,642,638 shares of Common Stock issued. Also on the date, the Company had 1,139,322 shares of Common Stock subject to outstanding options under the Company's Stock Option Plans. Accordingly, the Company has issued or reserved for issuance more than 71.8% of the authorized Common Stock, and, thus, a limited number of shares would be available to the Company for use in connection with any future corporate needs. The lack of authorized Common Stock available for issuance would limit the Company's ability to effectuate future stock splits or dividends. The Company would also be unnecessarily restricted in its ability to pursue opportunities for future acquisitions, mergers, financings and other corporate transactions. The Board of Directors believes that the increase in the authorized shares of Common Stock is necessary to provide the Company with the flexibility to pursue the types of opportunities described above without the added delay and expense of obtaining stockholder approval each time an opportunity requiring the issuance of shares may arise. This proposal could have an anti-takeover effect, although that is not its intention. For example, if the Company were the subject of a hostile takeover attempt, it could try to impede the takeover by issuing shares of Common Stock, thereby diluting the voting power of the other outstanding shares and increasing the potential cost of the takeover. The availability of this defensive strategy to the Company could discourage unsolicited takeover attempts, thereby limiting the opportunity for the stockholders to realize a higher price for their shares than is generally available in the public markets. The Board of Directors is not aware of any attempt, or contemplated attempt, to acquire control of the Company and this proposal is not being presented with the intent that it be utilized as a type of anti-takeover device. The additional shares of Common Stock to be authorized by adoption of the amendment to the Certificate of Incorporation would have rights identical to the current outstanding shares of Common Stock of the Company. Adoption of the proposed amendment to the Certificate of Incorporation would not affect the rights of the holders of current outstanding shares of Common Stock.

Under applicable Delaware law, the affirmative vote of the holders of a majority of the Common Stock outstanding on the record date is required to adopt the proposed amendment to the Certificate of Incorporation. As a result, abstentions and broker non-votes are effectively equivalent to votes against this proposal. Unless otherwise instructed, properly executed Proxies that are timely received and not subsequently revoked, but not marked, will be voted in favor of the proposed amendment to the Certificate of Incorporation. If the proposal is approved, the Company intends to file an amendment to the Certificate of Incorporation shortly after the meeting. The amendment to the Certificate of Incorporation will be effective immediately upon acceptance of filing by the Secretary of State of the State of Delaware. The Board of Directors would then be free to issue the newly authorized shares of Common Stock without further action on the part of the stockholders, subject to transactions requiring stockholder approval pursuant to the Company's Certificate of Incorporation or Delaware law. Attached as Exhibit B to this Proxy Statement is the text of the proposed amendment to the Company's Certificate of Incorporation. The Board of Directors recommends a vote "For" the proposal to increase the authorized Class A Common Stock. PROPOSAL NUMBER 3: Selection of Auditors The Board of Directors has reappointed the firm of Ernst & Young LLP as the Company's independent public accountants for the fiscal year ending May 31, 2001, subject to ratification by the Company's stockholders. Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting of Stockholders and will have an opportunity to make a statement, if they desire to do so, and to respond to appropriate questions from those attending the meeting. Ernst & Young LLP has served as auditors for the Company since 1984. The affirmative vote of holders of a majority of the shares of Common Stock present in person or represented by proxy at the Annual Meeting is required to ratify the appointment of Ernst & Young LLP as the independent accountants for fiscal 2001. The Board of Directors recommends a vote "For" ratification of Ernst & Young's appointment. Proposals of Stockholders A proposal of a stockholder intended to be presented at the next annual meeting of stockholders must be received at the Company's principal executive offices no later than May 31, 2001, if the proposal is to be considered for inclusion in the Company's proxy statement relating to such meeting.

Exhibit A --------- AUDIT COMMITTEE CHARTER Organization This charter governs the operations of the audit committee. The committee shall review and reassess the charter at least annually and obtain the approval of the board of directors. The committee shall be appointed by the board of directors and shall comprise at least three directors, each of whom are independent of management and the Company. Members of the committee shall be considered independent if they have no relationship that may interfere with the exercise of their independence from management and the Company. All committee members shall be financially literate, or shall become financially literate within a reasonable period of time after appointment to the committee and at least one member shall have accounting or related financial management expertise as defined under NASD regulations. Statement of Policy The audit committee shall provide assistance to the board of directors in fulfilling their oversight responsibility to the shareholders, potential shareholders, the investment community, and others relating to the Company's financial statements and the financial reporting process, the systems of internal accounting and financial controls, the internal audit function, the annual independent audit of the Company's financial statements, and the legal compliance and ethics programs as established by management and the board. In so doing, it is the responsibility of the committee to maintain free and open communication between the committee, independent auditors, the internal auditors and management of the Company. In discharging its oversight role, the committee is empowered to investigate any matter brought to its attention with full access to all books, records, facilities, and personnel of the Company and the power to retain outside counsel, or other experts, for this purpose. Responsibilities and Processes The primary responsibility of the audit committee is to oversee the Company's financial reporting process on behalf of the board and report the results of their activities to the board. Management is responsible for preparing the Company's financial statements, and the independent auditors are responsible for auditing those financial statements. The committee in carrying out its responsibilities believes its policies and procedures should remain flexible, in order to best react to changing conditions and circumstances. The committee should take the appropriate actions to set the overall corporate "tone" for quality financial reporting, sound business risk practices, and ethical behavior. The following shall be the principal recurring processes of the audit committee in carrying out its oversight responsibilities. The processes are set forth as a guide with the understanding that the committee may supplement them as appropriate. o The committee shall have a clear understanding with management and the independent auditors that the independent auditors are ultimately accountable to the board and the audit committee, as representatives of the Company's shareholders. The committee shall have the ultimate authority and responsibility to evaluate and, where appropriate, replace the independent auditors. The committee shall discuss with the auditors their independence from management and the Company and the matters included in the written disclosures required by the Independence Standards Board. Annually, the committee shall review and recommend to the board the selection of the Company's independent auditors, subject to shareholders' approval. o The committee shall discuss with the internal auditors and the independent auditors the overall scope and plans for their respective audits including the adequacy of staffing and compensation. Also, the committee shall discuss with management, the internal auditors, and the independent auditors the adequacy and effectiveness of the accounting and financial controls, including

the Company's system to monitor and manage business risk, and legal and ethical compliance programs. Further, the committee shall meet separately with the internal auditors and the independent auditors, with and without management present, to discuss the results of their examinations. o The committee shall review the interim financial statements with management and the independent auditors prior to the filing of the Company's Quarterly Report on Form 10-Q. Also, the committee shall discuss the results of the quarterly review and any other matters required to be communicated to the committee by the independent auditors under generally accepted auditing standards. The chair of the committee may represent the entire committee for the purposes of this review. o The committee shall review with management and the independent auditors the financial statements to be included in the Company's Annual Report on Form 10-K (or the annual report to shareholders if distributed prior to the filing of Form 10-K), including their judgment about the quality, not just acceptability, of accounting principles, the reasonableness of significant judgments, and the clarity of the disclosures in the financial statements. Also, the committee shall discuss the results of the annual audit and any other matters required to be communicated to the committee by the independent auditors under generally accepted auditing standards.

Exhibit B --------- The first sentence of Article Fourth of the Restated Certificate of Incorporation of Matrix Service Company shall be amended to read in its entirety as follows: "The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is 35 million, consisting of 5 million shares of Preferred Stock, par value $.01 per share (hereinafter called "Preferred Stock"), and 30 million shares of Common Stock, par value of $.01 per share (hereinafter called "Common Stock")."
