All Proxies which are properly completed, signed and returned to the Company prior to the Annual Meeting, and which have not been revoked, will unless otherwise directed by the stockholder be voted in accordance with the recommendations of the Board of Directors set forth in this Proxy Statement. A stockholder of record may revoke his or her Proxy at any time before it is voted either by filing with the Secretary of the Company, at its principal executive offices, a written notice of revocation or a duly executed proxy bearing a later date, or by attending the Annual Meeting and expressing a desire to vote his or her shares in person. The close of business on May 17, 1998 has been fixed as the record date for the determination of stockholders entitled to notice of and to vote at the Annual Meeting or at any adjournments or postponements of the Annual Meeting.

The term of the Employment Agreement is three years. Pursuant to the terms of the Employment Agreement, Mr. Chamberlain is to be paid an annual salary of $250,000 for each year of the Agreement, an annual bonus determined on the basis of the Company's existing management incentive plan which is limited to $100,000 for each year of the Agreement and is to receive certain additional benefits. In the event there is a "change of control" of the Company, Mr. Chamberlain may terminate his employment agreement, in which case, the Company is obligated to continue to pay Mr. Chamberlain his then-current base salary for a period of 12 months following the effective date of such termination. A "change of control" includes (i) the acquisition by any person or entity of shares of capital stock of the Company entitled to exercise 35% or more of the total voting power of the Company, (ii) the execution by the Company of an agreement to sell or otherwise transfer all or substantially all of its assets or the execution by the Company of an agreement to merge, consolidate or reorganize with any other corporation or entity, which results in less than 75% of the total voting power represented by the capital stock or other equity interests of the corporation or entity to which the Company's assets are sold or transferred or surviving such merger, consolidation or reorganization being held by the persons and entities who were holders of common stock of the Company on January 1, 1998, (iii) the issuance by the Company, otherwise than on a pro rata basis, of additional shares of capital stock representing (after giving effect to such issuance) more than 35% of the total voting power of the Company, or (iv) if the persons who were the directors of the Company as of January 1, 1998 cease to comprise a majority of the Board of Directors of the Company. STOCK OPTION PLAN The Company adopted a Stock Option Plan (the "1993 Plan") in 1993. The purpose of the 1993 Plan is to attract, retain and motivate certain key employees of the Company by giving them incentives which are linked directly to increases in the value of the Common Stock of the Company. Each officer, director and employee and under certain circumstances, consultants of the Company is eligible to be considered for the grant of awards under the 1993 Plan. The maximum number of shares of Common Stock that may be issued pursuant to awards granted under the 1993 Plan is 2,000,000, subject to certain adjustments to prevent dilution. Any shares of Common Page 8 Stock subject to an award which for any reason expires or terminates unexercised are again available for issuance under the 1993 Plan. The 1993 Plan authorizes the Compensation Committee to enter into any type of arrangement with an eligible employee that, by its terms, involves or might involve the issuance of (1) shares of Common Stock, (2) an option, warrant, convertible security, stock appreciation right or similar right with an exercise or conversion privilege at a price related to the Common Stock, or (3) any other security or benefit with a value derived from the value of the Common Stock. Any stock option granted may be an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") or a nonqualified stock option. The 1993 Plan currently is administered by the Compensation Committee of the Board of Directors of the Company. Subject to the provisions of the 1993 Plan, the Compensation Committee will have full and final authority to select the executives and other employees to whom awards will be granted thereunder, to grant the awards and to determine the terms and conditions of the awards and the number of shares to be issued pursuant thereto. As of December 31, 1998, the Board had granted options covering an aggregate of 3,468,950 of Common Stock to certain directors, officers and employees of the Company, of which options to purchase 2,117,646 were outstanding. SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, requires the Company's executive officers, directors, and persons who own more than ten percent of a registered class of the Company's equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission (the "SEC"). Executive officers, directors and greater-than-ten percent stockholders are required by SEC regulations to furnish the Company with all Section 16(a) forms they file. Based solely on its review of the copies of the forms received by it and written representations from certain reporting persons that they have complied with the relevant filing requirements, the Company believes that, during the year ended December 31, 1998, all the Company's executive officers, directors and greater-than-ten percent stockholders complied with all Section 16(a) filing requirements, except that James H. Chamberlain reported the disposition by gift of 2000 shares of Common Stock to the University of West Virginia on a Form 5 filed prior to February 15, 1999 with respect to the transaction which occurred on December 10, 1998. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS WITH DIRECTORS AND EXECUTIVE OFFICERS The Company's Chairman of the Board, President, and Chief Executive Officer, James H. Chamberlain, is indebted to the Company in the aggregate principal amount of $434,000 as of May 31, 1998, which was the largest aggregate amount of such indebtedness during fiscal 1997. The loans are represented by two separate promissory notes, one in the principal amount of $350,000, bearing interest 5.9% per annum, and one in the principal amount of $84,000, bearing interest at 5.51% per annum. Each loan provides for interest only payments, payable monthly, with all principal due upon demand.
