Meetings of the Board of Directors and Certain Committees of the Board



During the fiscal year ended September 30, 2003, the Board of Directors of
the Company held 5 meetings. All Directors attended more than 75% of the meetings.



The Compensation Committee endeavors to ensure that the compensation program for executive officers of the Company is effective in attracting and retaining key executives responsible for the success of the Company and
in promoting its long-term interests and those of its stockholders. The committee, without applying any specific quantitative formulas, considers such factors as net income, earnings per share, duties and scope of responsibility, industry standards
and comparable salaries for the geographic area, corporate growth, profits, goals and market share increases. The functions of the Compensation Committee include establishment of compensation plans for Gencors executive officers and
administration of certain of Gencors employee benefit and compensation programs. During the fiscal year ended September 30, 2003, the Compensation Committee had one meeting which was attended by all members.



The Audit Committees responsibilities include selecting the
Companys auditors and reviewing the Companys audit plan, financial statements and internal accounting and audit procedures. The Audit Committee Charter was adopted by the Board of Directors and a copy is included in last years
Proxy Statement. During the fiscal year ended September 30, 2003, the Audit Committee had three meetings which were attended by all members. The Companys 2003 fiscal year Audit Committee was initially composed of three board members, two of
whom were independent as per NASDAQ definitions. The two independent Audit Committee members resigned from the Board of Directors on June 2, 2003 at which time the Audit Committee functions were assumed by the Board of Directors until January 16,
2004 when the Board of Directors elected two new replacement directors, Mr. David A. Air and Mr. Russell R. Lee, III. Messrs. Air and Lee are considered independent by NASDAQ rules. Mr. Lee now serves as the audit committee financial
expert.



The Nominating Committee of the Company does not
have a charter, but intends to develop one in the next fiscal year. At present the three members of the Nominating Committee are E. J. Elliott, John Elliott and Randolph Fields, none of whom are considered independent by NASDAQ rules.
The Nominating Committee has developed guidelines with respect to whom it might consider for director candidates by stockholders or others, and believes that for smaller companies it is desirable and beneficial to recommend board candidates who
possess a proven track record in heavy manufacturing operations, understand the companys overall business, and are able to make maximum contribution to guiding the Companys affairs. Accordingly, the Nominating Committee reviews
recommendations of its individual members and gives considerable weight to candidates with industry-related experience and expertise that will benefit the Company. Additionally, the Nominating Committee believes that persons selected must have a
serious work ethic and an ability to work as a constructive member of a team for the benefit of the stockholders.



Beneficial Ownership Reporting Compliance



Section 16(a) of the Exchange Act requires the Companys directors, officers and certain stockholders to file with the Commission an initial
statement of beneficial ownership and certain statements of changes in beneficial ownership of equity securities of the Company. Based solely on its review of such forms received by it, the Company is unaware of any instances of noncompliance, or
late compliance, with such filings during the fiscal year ended September 30, 2003, by its officers, directors or stockholders.



Directors Fees



Directors fees are paid by the Company to non-employee directors at the rate of $1,000 per month, plus $1,000 per meeting attended. Total fees paid
in fiscal 2003 were $47,000.

Communications with Directors



The Company has a process for holders of common stock to communicate with the boards of directors which request that
such holders mail their communication by United States mail to the Companys headquarters and to the attention of the director or directors with whom one wants to communicate c/o the Chief Executive Officer of the Company. The Chief Executive
Officer shall cause this communication to be forwarded to the directors on a regular basis as soon as practicable.



Code of Ethics



The Company has adopted a code of ethics that applies to the Companys principal executive officer, principal accounting officer and persons
performing similar functions. The Company will provide to any person without charge, upon written request, addressed to its corporate headquarters, attention Corporate Secretary, a copy of such code of ethics.

REPORT OF THE AUDIT COMMITTEE



Management is responsible for the preparation, presentation and integrity of the Companys financial statements,
accounting and financial reporting principles and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The independent auditors, Moore Stephens Lovelace, P. A., are responsible
for performing an independent audit of the consolidated financial statements in accordance with generally accepted auditing standards.



In performing its oversight role, the Audit Committee has considered and discussed the audited financial statements with management. The Audit Committee
has also discussed with the independent auditors the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees,as currently in effect. The Audit Committee has received the written
disclosures and the letter from the independent auditors required by Independence Standards Board Standard No. 1, Independent Discussions with Audit Committees, as currently in effect, and has discussed with the auditors the auditors
independence.



Based on the review and discussions described in
this report, and subject to the limitations on the role and responsibilities of the Audit Committee with regard to its oversight functions referred to below, the Audit Committee approved the audited financial statements for inclusion in the
Companys Annual Report on Form 10-K for the fiscal years ended September 30, 2003, for filing with the Securities and Exchange Commission.



The members of the Audit Committee are not professionally engaged by the Company to practice auditing or accounting and the present members are not
experts in the fields of accounting or auditing, including with respect to matters of auditor independence. Members of the Audit Committee rely without independent verification on the information provided to them and on the representations made by
management and the independent auditors. Accordingly, the Audit Committees oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate
internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committees considerations and discussions referred to above do not assure that the audit of
the Companys financial statements has been carried out in accordance with generally accepted auditing standards that the financial statements are presented in accordance with generally accepted accounting principles or that Moore Stephens
Lovelace, P.A. is in fact independent.

REPORT OF THE COMPENSATION COMMITTEE



General



During fiscal year 2003 the Compensation Committee (the Committee) of the Board of Directors consisted of the directors of the Company. The
Compensation Committee administers the Companys executive compensation program, monitors corporate performance and its relationship to compensation for executive officers, and makes appropriate recommendations concerning matters of executive
compensation.



Compensation Philosophy



One of the major objectives of the Committee has been to develop and
implement a compensation program designed to attract, motivate, reward and retain the broad-based management talent required to achieve the Companys business objectives. The Committee believed that offering a competitive base salary and
certain incentives designed to encourage achievement of the Companys objectives were the two major components of its compensation philosophy.



Base Salary



The Companys salary levels for executive officers are intended to be consistent with competitive pay practices of similar sized companies within the
industry. In determining executive officers salaries, the Compensation Committee considered such factors as the level of responsibility, competitive trends, the financial performance and resources of the Company. An individuals
experience level, overall job performance, prior service and job knowledge were also important considerations.



Incentives



Incentives
consist of stock options and, to a lesser extent, cash awards. The Committee believes that the compensation program should provide employees with an opportunity to increase their ownership and potential for financial gain from increases in the
Companys stock price. This approach closely aligns the interests of shareholders, executives and employees. Therefore, executives and other employees are eligible to receive stock options, giving them the right to purchase shares of the
Companys Common Stock at a specified price in the future. The grant of options is based primarily on a key employees potential contribution to the Companys growth and profitability, as measured by the market value of the
Companys Common Stock. The granting of cash awards is discretionary and is not dependent on any one factor.
