                                             Chairman of the Board, President

                               GENERAL INFORMATION

Q:       Who is soliciting my proxy?

A:       We--the Board of Directors of Probex Corp.--are sending you this Proxy
         Statement in connection with our solicitation of proxies for use at our
         February 28, 2001 Annual Meeting of Stockholders and at any adjournment
         of the meeting. Certain of our officers and employees also may solicit
         proxies on our behalf by mail, phone, fax or in person.

Q:       Who is paying for this solicitation?

A:       We will pay for the solicitation of proxies, including out-of-pocket
         expenses estimated to be $15,000. We also will reimburse banks,
         brokers, custodians, nominees and fiduciaries for their reasonable
         charges and expenses to forward our proxy materials to the beneficial
         owners of our common stock.

Q:       What am I voting on?

A:       You are voting on the following:

         o   The election of six directors. If you approve Proposal Two, the
             directors will serve in staggered terms of one, two and three
             years. If you do not approve Proposal Two, the directors will be
             elected for one year terms;

         o   The proposal to amend our Certificate of Incorporation to provide
             for a classified Board of Directors;

         o   The proposal to amend our Certificate of Incorporation to remove
             the ability of stockholders to act by written consent;

         o   The proposal to authorize the issuance of up to 25 million shares
             of our common stock;

         o   The proposal to amend our 1999 Omnibus Stock and Incentive Plan, as
             amended and restated, to increase the number shares available under
             such plan; and

         o   The ratification of the appointment of Ernst & Young LLP as our
             independent auditors.

Q:       Who can vote?

A:       Stockholders of record of our common stock at the close of business on
         January 12, 2001, are entitled to vote at the meeting. Each stockholder
         is entitled to cast one vote for each share of common stock owned.

Q.       How do I vote?

A.       You may vote in person at the meeting or by proxy. We recommend you
         vote by proxy even if you plan to attend the meeting. You can always
         change your vote at the meeting. If you have shares held by a broker or
         other nominee, you may instruct your broker or nominee to vote your
         shares by following the instructions that the broker or nominee
         provides you. Most brokers offer voting by mail, telephone and
         Internet.

Q.       How do proxies work?

A.       The Board of Directors of Probex Corp. is asking for your proxy. Giving
         your proxy to the persons named by us means you authorize them to vote
         your shares at the meeting in the manner you direct.

         If you sign and return the enclosed proxy card but do not specify how
         your shares are to be voted, your shares will be voted FOR the election
         of each of the six directors nominated for one, two and three year
         terms, FOR the proposal to amend our Certificate of Incorporation to
         provide for a classified Board of Directors, FOR the proposal to amend
         our Certificate of Incorporation to remove the ability of stockholders
         to act by written consent, FOR the proposal to approve the issuance of
         up to 25 million shares of our common stock, FOR the proposal to amend
         our 1999 Omnibus Stock and Incentive Plan, as amended and restated, to
         increase the numbers of shares available under such plan, and FOR the
         ratification of the appointment of Ernst & Young LLP as our independent
         auditors.

Q:       What constitutes a quorum?

A:       On January 12, 2001, we had 26,226,534 shares of common stock, $0.001
         par value per share, outstanding. Voting can take place at the Annual
         Meeting only if stockholders owning a majority of the voting power of
         the common stock (that is, a majority of the total number of votes
         entitled to be cast) are present, either in person or by proxy. If you
         do not vote, or if a broker holding your shares in "street" or
         "nominee" name indicates to us on a proxy that you have not voted and
         it lacks discretionary authority to vote your shares, we will not
         consider your shares as present or entitled to vote for any purpose.

         You may receive more than one proxy or voting card depending on how you
         hold your shares. Shares registered in your name are covered by one
         card. If you also hold shares through a broker or other nominee, you
         may also get material from them asking how you want to vote. To be sure
         that all of your shares are voted, we encourage you to respond to each
         request you receive.

Q.       How do I revoke a proxy?

A.       You may revoke your proxy before it is voted by submitting a new proxy
         with a later date; by voting in person at the meeting; or by notifying
         Probex's Secretary in writing at the address listed on the cover
         letter.

Q.       Will my shares be voted if I don't sign a proxy?

A.       If you hold your shares directly in your own name, they will not be
         voted unless you provide a signed proxy. Under certain circumstances,
         shares which you own that are held by a broker may be voted even if you
         do not provide voting instructions to the broker. Brokerage firms have
         the authority under the American Stock Exchange rules to vote
         customers' unvoted shares on certain "routine" matters. The election of
         directors and the ratification of the appointment of Ernst & Young LLP
         as the Company's independent auditors are considered to be "routine"
         matters, and, therefore, your broker has the authority to vote your
         unvoted shares for or against the directors nominated and the
         ratification of the appointment of Ernst & Young LLP. The proposal to
         amend our Certificate of Incorporation to provide for a classified
         Board of Directors, the proposal to amend our Certificate of
         Incorporation to remove the ability of stockholders to act by written
         consent, the proposal to approve the issuance of up to 25 million
         shares of our common stock, and the proposal to amend our 1999 Omnibus
         Stock and Incentive Plan, as amended and restated, to increase the
         number of shares available under such plan, are not "routine" matters,
         and, therefore, your shares will not be voted on these matters if your
         proxy is not signed.

Q.       How many votes are needed for approval?

A.       The six director candidates receiving the most "FOR" votes will be
         elected to the six seats on the Board to be filled at the meeting. The
         terms of the six directors will either be for one-year terms or one,
         two and three years terms, subject to the results of Proposal Two
         submitted to stockholders by this Proxy Statement. Abstentions,
         withholding authority to vote for a candidate and broker non-votes will
         only reduce the number of votes a candidate receives.

         Approval of the amendments to our Certificate of Incorporation to
         provide for a classified Board of Directors and to remove the ability
         of stockholders to act by written consent, each requires the
         affirmative vote of a majority of the shares outstanding. For this
         purpose, an abstention and a broker non-vote will have the same effect
         as a vote against the proposal.

         Approval of the issuance of up to 25 million shares of our common
         stock, the amendment to the 1999 Omnibus Stock and Incentive Plan, as
         amended and restated, to increase the number of shares available under
         such plan, and the ratification of the appointment of Ernst & Young LLP
         as our independent auditors, each requires the affirmative vote of a
         majority of the shares present in person or by proxy and entitled to
         vote at the meeting. For this purpose, an abstention will have the same
         effect as a vote against the



                                       2

         proposals. Broker non-votes will not be counted as a vote either for or
         against the proposals and will not be counted in determining the number
         of shares entitled to vote on the proposals.

         A "broker non-vote" occurs when a broker submits a proxy but does not
         vote for or against a matter. This will occur when the beneficial owner
         has not instructed the broker how to vote and the broker does not have
         discretionary authority to vote in the absence of instructions.

Q:       What should I do if I want to attend in person?

A:       Only stockholders of record, their proxy holders, and invited guests
         may attend the meeting. If you wish to vote in person and your shares
         are held by a broker or nominee, you will need to obtain a proxy from
         the broker or nominee authorizing you to vote your shares held in their
         name.

                                  PROPOSAL ONE

                              ELECTION OF DIRECTORS

         Our Board of Directors has nominated the six director candidates named
below.

         Our Board of Directors oversees the management of the Company on your
behalf. The Board reviews the Company's long-term strategic plans and exercises
direct decision-making authority on key issues, such as the terms of material
agreements. Just as important, the Board chooses the Chief Executive Officer,
sets the scope of his authority to manage the Company's day-to-day operations,
and evaluates his performance.

         Four of our six nominees are outside directors, meaning those who are
not otherwise current employees of the Company. Of these four nominees, at least
two, and perhaps three, are independent directors, as set forth by the rules of
the American Stock Exchange, on which our common stock is listed. Independent
directors are not officers of the Company and are, in the view of our Board of
Directors, free of any relationship that would interfere with the exercise of
independent judgment. The following persons are not considered to be
independent: (a) a director who is employed by the Company or any of its
affiliates for the current year or any of the past three years; (b) a director
who accepts any compensation from the Company or any of its affiliates in excess
of $60,000 during the previous fiscal year, other than compensation for Board

DIRECTOR COMPENSATION

         We do not pay cash compensation to our Board of Directors. In August
1999, our Board of Directors approved the issuance to each outside
(non-employee) director warrants to purchase 100,000 shares of our common stock
at $0.50 per share for a five-year period ending August 2004, of which 60,000
vested immediately and the remaining 40,000 are subject to achievement of
certain performance conditions. Messrs. Jones, Maselli and Plaskett were each
issued these warrants as compensation for services rendered as directors for the
1998 calendar year.

         In March 2000, the Board of Directors approved a compensation program
for our outside directors, which was modified in December 2000. Under this
program, any new outside director will receive options to purchase 10,000 shares
(5,000 shares in the case of any new advisory director) of common stock on the
date the director is elected to the Board of Directors, at the fair market value
(generally the closing price of the common stock as reported on the AMEX) on the
date of such grant. In addition, all outside directors will be entitled to
receive, on an annual basis, options to purchase 25,000 shares (12,500 shares in
the case of advisory directors) of common stock as of the date of the annual
meeting of stockholders for services rendered during the calendar year in which
the annual stockholders' meeting is held. The grant will be made on the date of
the annual meeting in each year starting with the annual meeting of stockholders
to be held in 2001 for the 2001 calendar year. The determination of directors as
outside directors will be made as of such date, and any grant will not be
subject to adjustment or proration due to a subsequent change in a director's
classification as an outside director or due to any subsequent resignation,
removal or death of a director during such calendar year.

         In connection with the implementation of this program, our Board of
Directors also approved the grant of options as compensation for calendar years
1999 and 2000, as follows:

         o as compensation for calendar year 1999, options to purchase 25,000
shares of common stock were granted to each of Messrs. Jones, Maselli and
Plaskett, and 12,500 shares of common stock were granted to each of Messrs.
Hollingshad and Searles, at an exercise price equal to $3.75 per share (the
closing price of the common stock as of March 30, 2000, the date the
compensation plan was originally adopted); and

         o as compensation for calendar year 2000, options to purchase 25,000
shares of common stock were granted to each of Messrs. Jones, Maselli, Murray
and Plaskett, and 12,500 shares of common stock were granted to each of Messrs.
Hollingshad and Searles, at an exercise price equal to the closing price of the
common stock as of the close of business on December 29, 2000 (the last business
day of the calendar year). The grant of these options is subject to stockholder
approval of Proposal Five, the amendment to the Company's 1999 Omnibus Stock and
Incentive Plan, as amended and restated.

         We also reimburse directors for any out-of-pocket expenses incurred by
them in conjunction with the business.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

Compensation Philosophy

         The Compensation Committee works with senior management to develop and
implement the Company's executive compensation philosophy. Generally, the
Company's philosophy on executive compensation has been to provide a base cash
compensation that is at or below the average of other comparable companies, and
to provide additional incentive compensation in the form of cash bonuses and
grants of stock options based on the realization of stated objectives, such as
acquisitions, financings and other similar criteria expected to result in
improvements in total stockholder return. The Compensation Committee recognizes,
however, that in order to continue to grant options under the existing 1999
Omnibus Stock and Incentive Plan, as amended and restated (the "1999 Plan"), the
existing 1999 Plan will have to be amended to permit the grant of additional
shares. Such an amendment has been approved by the Board of Directors based upon
the recommendation of the Compensation Committee and is being submitted to the
stockholders for their approval at the 2001 Annual Meeting of Stockholders. See
"Amendment of 1999 Omnibus Stock and Incentive Plan, as amended and restated."
The programs proposed to be implemented by the Compensation Committee will be
retroactive to fiscal 2000.

Executive Compensation

         Mr. Rampacek, the Company's Chairman of the Board, President and Chief
Executive Officer receives a base salary of $180,000 per year. This base cash
compensation, like that paid to other executive officers, is related primarily
to competitive factors and is not tied to the Company's financial performance or
the achievement of specific goals. The base compensation of the Company's
executive officers was increased in fiscal 2000 over fiscal 1999 levels to bring
them more nearly in line with the base compensation being paid by competitive
companies. In evaluating these increases the Committee also considered the
overall performance of the executive officers, in light of their objective and
subjective contributions to the Company's success. In addition to base salary,
options to purchase shares of common stock were awarded to certain of the
Company's executive officers during fiscal 2000.

Other Incentive Compensation

         Awards of stock options were made in fiscal 2000 to Messrs. MacDonald,
Hall, McNiel and Rampacek, executive officers of the Company. In March 2000, the
Compensation Committee, subject to stockholder approval, approved the 1999 Plan.
The 1999 Plan was subsequently approved by stockholders at a special meeting of
stockholders held in July 2000. Additionally, in March 2000 the Committee
approved a director compensation program, which was subsequently amended in
December 2000 (See "Director Compensation"). These grants were made for services
rendered by the members of the Board.

<PAGE>   17


Employment Arrangements

         The Company is currently finalizing employment agreements with Mr.
Rampacek and Mr. McNiel that continue in effect until August 31, 2005. Under
these agreements, Mr. Rampacek serves as the President and Chief Executive
Officer of the Company and Mr. McNiel serves as Senior Vice President of
Operations.

         None of the other officers of the Company has an employment agreement.

         The Company also maintains a 401(k) Plan, health insurance and other
benefits generally available to all employees. Currently the Company makes no
matching or other contributions to this plan, other than the payment of its
operating and administrative expenses.

         This report has been furnished by the current members of the
Compensation Committee.

1.       Represents grant of options to purchase 50,000 shares of common stock
         of the Company at an exercise price of $0.50 per share as a performance
         bonus. Such option vested upon grant.

2.       In July 1999, the Board of Directors approved and the Company adopted
         the 1999 Omnibus Stock and Incentive Plan for certain employees to
         purchase common stock of the Company. Effective July 22, 1999, the
         Company approved the issuance of options to purchase 2,748,000 shares
         of common stock to employees of the Company. The exercise price is
         $0.50 per share and each option is generally exercisable after meeting
         five equally weighted goals over a maximum ten-year vesting period. As
         of September 30, 1999, all of these options had been granted but none
         had been vested or exercised. Mr. MacDonald was granted 370,000 options
         under this issuance.

3.       In October 1999, Mr. Plaskett assumed the additional responsibilities
         of Chief Executive Officer and President of the Company on an interim
         basis in addition to his continuing role as Chairman of the Board. Mr.
         Plaskett was not paid any cash compensation in these roles but was
         granted a warrant to purchase 250,000 shares of common stock of the
         Company at $1.00 per share for a five-year period. 50% of this award,
         or 125,000 shares, vested immediately upon issuance and the remaining
         50%, or 125,000 shares, have not vested. Additionally, in August 1999,
         the Board of Directors approved the issuance to each outside (non
         employee) director warrants to purchase 100,000 shares of common stock
         of the Company at $0.50 per share for a five-year period. Mr. Plaskett
         received a warrant to purchase 100,000 shares of common stock of the
         Company, of which 60,000 vested immediately and the remaining 40,000
         will vest subject to the Company achieving certain performance
         milestones. This warrant represents compensation for Mr. Plaskett's
         services as a director, and does not relate to services provided as the
         interim President and Chief Executive Officer of the Company.

4.       Represents options to purchase 100,000 shares of common stock at an
         exercise price of $1.875 per share granted under the Company's 1999
         Omnibus Stock and Incentive Plan, as amended and restated, as
         additional compensation for services rendered.

         upon his election to the Board of Directors. These options represent
         compensation for Mr. Rampacek's services as a director and do not
         relate to services provided as the current President and Chief
         Executive Officer of the Company. The options are exercisable at $3.437
         per share and expire in April 2010.

         ratably over the next four years on the date of initial employment.

     AUDIT COMMITTEE REPORT

         The Audit Committee is composed of two directors and operates under a
charter adopted by the Board of Directors. The Board of Directors believes that
both of these directors are independent as defined by the American Stock
Exchange's Listed Company Guide. The Board of Directors, however, acknowledges
that Mr. Plaskett's services as the interim President and Chief Executive
Officer of the Company from October 1999 to July 2000 may disqualify him as
having been employed by the Company or any of its affiliates for the current or
preceding three years. The Board intends to seek clarification from the American
Stock Exchange regarding Mr. Plaskett's status. In light of the interim nature
of Mr. Plaskett's duties and the fact that he received no cash compensation for
his services, maintained his primary occupation unrelated to the Company, and
was only present on an as needed basis, the Board does not believe Mr. Plaskett
was an "employee" of the Company for purposes of the American Stock Exchange
Rules. Nevertheless, the Board has nominated Dr. Gower for election at this
annual meeting, and if elected, intends to add Dr. Gower to the Audit Committee.
Therefore, if the American Stock Exchange ultimately determines that the Company
is not in compliance, the election of Dr. Gower would resolve any such
non-compliance. A copy of the Audit Committee Charter is attached to this Proxy
Statement as Exhibit C.

         Management is responsible for the Company's internal controls and the
financial reporting process. Ernst & Young LLP, the Company's independent
auditors, are responsible for performing an independent audit of the Company's
consolidated financial statements in accordance with generally accepted auditing
standards. The Audit Committee's responsibility is to monitor and oversee these
processes.

         In this context, the Audit Committee reviewed and discussed the audited
financial statements with both management and Ernst & Young LLP. Specifically,
the Audit Committee has discussed with Ernst & Young LLP matters required to be
discussed by SAS 61 (Codification of Statements on Auditing Standards, AU
Section 380).

         The Audit Committee received from Ernst & Young LLP the written
disclosures and the letter required by Independence Standards Board Standard No.
1 ( Independence Discussions with Audit Committees), and has discussed with
Ernst & Young LLP the issue of its independence from the Company.

         Based on the Audit Committee's review of the audited financial
statements and its discussions with management and Ernst & Young LLP noted
above, the Audit Committee recommended to the Board of Directors that the
audited consolidated financial statements be included in the Company's Annual
Report on Form 10-KSB for the year ended September 30, 2000.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

         Section 16(a) of the Exchange Act requires directors and certain
officers, and persons who beneficially own more than ten percent (10%) of the
Company's stock, to file initial reports of ownership and reports of changes in
ownership with the Securities and Exchange Commission. Directors, certain
officers and greater than ten percent (10%) beneficial owners are required by
the Securities and Exchange Commission regulations to furnish the Company with
copies of all Section 16(a) forms they file.

         Based solely on a review of the copies furnished to the Company and
representations from the directors and certain officers, the Company believes
that all Section 16(a) filing requirements for the year ended September 30, 2000
applicable to its directors, certain officers and greater than ten percent (10%)
beneficial owners were satisfied, other than a Form 4 and amended Form 4 filed
late by Mr. Maselli, a director of the Company. This Form 4 and amended Form 4
reflected the exercise of stock options and a single sale of common stock
derived from the exercise of the stock option.

         Based on representations from the directors and certain officers, the
Company believes that no other Forms 5 for directors, certain officers and
greater than ten percent (10%) beneficial owners were required to be filed with
the Securities and Exchange Commission for the period ended November 30, 2000.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Anthony J. Maselli, a director since June 1998, is the Founder and
Managing Director of HSB Engineering Finance Corporation (HSB Engineering) and a
Vice President of the Technology Risks Department of Hartford Steam Boiler
Inspection & Insurance Company. Mr. Maselli has been with HSB Engineering since
1995. On June 30, 1998, Probex and HSB Engineering, a wholly-owned subsidiary of
Hartford Steam Boiler Inspection & Insurance Company, entered into an agreement
whereby HSB Engineering agreed to loan up to $1,500,000 for working capital
purposes. In exchange for the loan, we granted a ten-year warrant to purchase
shares of our common stock at $0.01 per share equal to 10% of the number of
shares of common stock outstanding on a fully diluted basis.

         On June 6, 2000, HSB Engineering exercised a loan conversion of the
then outstanding loan balance of $750,000, resulting in us issuing 2,796,114
shares of common stock to HSB Engineering. In addition, we paid accrued interest
of $188,625 due under the convertible promissory note. Upon conversion of the
loan, we also amended certain rights previously to granted HSB Engineering. Such
amended rights include the following:

         o        HSB Engineering can appoint one member to be nominated for
                  election to our Board of Directors and all committees thereof
                  as long as they, together with their affiliates, in the
                  aggregate, hold common stock representing at least five
                  percent of our common stock outstanding.

         o        So long as HSB Engineering, together with their affiliates, in
                  the aggregate, hold common stock representing at least five
                  percent of our common stock outstanding, our Board of
                  Directors may not take action to increase the number of voting
                  directors constituting the Board of Directors to a number
                  greater than nine, without the affirmative vote of their
                  representative.

         o        So long as HSB Engineering, together with their affiliates, in
                  the aggregate, hold common stock representing at least five
                  percent of our common stock outstanding, we may not
                  participate in any significant transaction if their
                  representative and at least one other outside director votes
                  against such significant transaction. These significant
                  transactions include mergers, asset sales, changes in our
                  authorized stock, and the creation of any additional class of
                  capital stock.

         Thomas G. Murray, a director since 1994 was also the Chief Executive
Officer of the Company until October 1999, and thereafter was a Senior Vice
President of the Company until his resignation on May 31, 2000. In connection
with his resignation, the Company entered into an employment agreement with Mr.
Murray whereby Mr. Murray agreed to continue to provide services to the Company
as a non-executive employee until January 2002. In exchange for these services,
we have agreed to pay Mr. Murray cash compensation of $90,000 annually, and to
provide Mr. Murray with certain other employee benefits, in each case, through
June 30, 2001. In addition, we modified the terms of certain options previously
issued to Mr. Murray to permit those options to vest at certain time intervals,
rather than upon the occurrence of certain specified events. As a result,
one-third of Mr. Murray's options to purchase 490,000 shares of common stock at
$.50 per share vested on May 31, 2000, and one-third of his options will vest on
January 1 of 2001 and 2002.

         Nicholas W. Hollingshad, an advisory director since April 1999, is a
principal of Environmental Resources Management (ERM), an international
industrial environmental firm. We have engaged ERM to provide environmental due
diligence and permitting service in connection with the development of our
initial plant in Wellsville, Ohio. Pursuant to such engagement, for the fiscal
year ended September 30, 2000, we paid ERM an aggregate of $96,925.
Additionally, as of January 5, 2001, we have paid ERM $204,168 and expect to pay
in excess of $400,000 during the current fiscal year.

         William A. Searles, an advisory director since November 1999, is the
Chairman of APS Investment Services, Inc. We engaged APS Financial Corporation,
an affiliate of APS Investment Services, Inc., to serve as the placement agent
for our private placement of Series A Preferred Stock. As a result of such
engagement, we paid


                                       18
<PAGE>   23


APS Financial Corporation a total of $588,500 in cash commissions and issued to
APS Financial Corporation five-year warrants to purchase a total of 402,000
shares of common stock at a purchase price of $1.875 per share.

         Nora A. Blum, a recently elected advisory director in December 2000, is
a Vice President of Bechtel Enterprises, Inc. We entered into a memorandum of
understanding with Bechtel Corporation, an affiliate of Bechtel Enterprises,
Inc. in February 2000 to negotiate a strategic worldwide alliance. Additionally,
we are currently negotiating an engineering, procurement and construction
contract with Bechtel Corporation (Bechtel) for the construction of our first
plant in Wellsville, Ohio. In connection with services rendered to us by
Bechtel, we paid Bechtel $2,015,251 during the fiscal year ended September 30,
2000. As of January 5, 2001, we have paid Bechtel $3,352,768 and expect to pay
Bechtel $4,239,000 during the first calendar quarter of 2001. The expected
payments totaling $4,239,000 consists of: $757,000 for preliminary engineering
fees, $2,482,000 for engineering, procurement and construction advances, and
$1,000,000 that was deferred.

         Bechtel has invested $600,000 in us and also possesses a warrant to
purchase up to 200,000 shares of our common stock at exercise price of $3.00 per
share. Further, United Infrastructure Company, LLC, an affiliate of Bechtel
Enterprises, Inc., has made a direct equity investment in us totaling $1
million. United Infrastructure Company, LLC also agreed, subject to certain
mutually agreed upon conditions, to make additional direct equity investments in
us totaling $4 million toward the financing of the Wellsville plant.

                                  PROPOSAL TWO

                  AMENDMENT TO THE CERTIFICATE OF INCORPORATION
                  TO IMPLEMENT A CLASSIFIED BOARD OF DIRECTORS

Proposal

         The Board of Directors has unanimously approved and recommended for
stockholder approval an amendment to the Certificate of Incorporation to add a
new article providing for a classified Board of Directors, the text of which is
set forth in Exhibit A to this Proxy Statement (the "Classified Board
Amendment"). Under Delaware law, the amendment would become effective upon
stockholder approval and filing of the amendment to the Certificate of
Incorporation.

         The Classified Board Amendment provides that, at this Annual Meeting,
the Company's Board of Directors will be divided into three classes (denominated
Class I, Class II and Class III) which shall be as nearly equal in number as
possible. The directors in each class will hold office following their initial
classification for terms of one year, two years and three years, respectively.
Thus, the term of office of the Class I Directors will expire at the year 2002
Annual Meeting of Stockholders, the term of office of the Class II Directors
will expire at the year 2003 Annual Meeting of Stockholders, and the term of
office of the Class III Directors will expire at the year 2004 Annual Meeting of
Stockholders. Thereafter, the successors to each class of directors shall be
elected for three-year terms. If this proposal is not approved, each director
will be elected to serve for a term of one year and until their successors are
duly elected and qualified.

         Under Delaware law, a director of a corporation with a classified board
of directors may be removed by the stockholders only for cause unless the
corporation's certificate of incorporation provides otherwise. The Company's
Certificate of Incorporation does not provide otherwise. Therefore, if this
proposal is approved, the holders of a majority of the outstanding voting shares
would be able to remove a director during his or her elected term only for
"cause." In this context, "cause" is not defined by statute. If a vacancy occurs
during the term of any director, under Delaware law the majority of the Board of
Directors may fill the vacancy, and the director so appointed will hold office
until the next election of the class to which he or she was appointed.

         Classification of the Board of Directors will promote continuity and
stability in the Company's management and policies since a majority of the
Company's directors at any given time will have prior experience with the
Company. The Board of Directors further believes that such continuity and
stability will facilitate long-range planning and will have a beneficial effect
on employee loyalty and customer confidence. Currently, the entire Board of
Directors must stand for election each year. Accordingly, it is possible that
all or a majority of the current directors could be replaced at any given Annual
Meeting. If this proposal is approved, the Board of Directors will be divided
into three classes effective with this 2001 Annual Meeting, only one of which
classes will stand for election at each Annual Meeting thereafter.

         In addition, classification of the Board of Directors may have the
effect of delaying, deferring or preventing a change of control of the Company
since only one-third of the directors are up for election each year and
directors may not be removed, except for cause. The Board of Directors believes
that increased management stability and continuity fostered by the classified
Board of Directors will enhance the capacity of the Board of Directors to defend
against undesirable takeover attempts and, in the event of the sale of the
Company, would enhance the Board of Directors' ability to negotiate a
transaction that is in the stockholders' best interest. The proposed
classification of the Board of Directors is not being recommended in response to
a pending or threatened attempt to acquire control of the Company.

Vote Necessary to Approve the Proposal

         The affirmative vote of the holders of a majority of the outstanding
shares of common stock is necessary for approval of the Classified Board
Amendment. Therefore, abstentions and broker non-votes effectively count as
votes against the Amendment.

  THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ADOPTION OF THE PROPOSED
         AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO PROVIDE FOR A
                         CLASSIFIED BOARD OF DIRECTORS.


                                 PROPOSAL THREE

                  AMENDMENT TO THE CERTIFICATE OF INCORPORATION
                    TO REMOVE THE ABILITY OF STOCKHOLDERS TO
                             ACT BY WRITTEN CONSENT


Proposal

         The Board of Directors has unanimously approved and recommended for
stockholder approval an amendment to the Certificate of Incorporation to add a
new article removing the ability of stockholders to act by written consent, the
text of which is set forth in Exhibit B to this Proxy Statement (the "Action by
Written Consent Amendment"). Under Delaware law, the amendment would become
effective upon stockholder approval and filing of the amendment to the
Certificate of Incorporation.

         Currently, any action which may be taken at any annual or special
meeting of stockholders of the Company may be taken without a meeting, without
prior notice, and without a vote, if a written consent or consents, setting
forth the action so taken, is signed by the holders of the shares having not
less than the minimum number of votes necessary to take such action at a meeting
at which the holders of all shares entitled to vote on the action were present
and voted. In short, this provision allows a stockholder or group of
stockholders who own 50% of the outstanding shares (or more with respect to
provisions requiring supermajority approval) to take action, such as electing or
removing directors, by written consent without the necessity of holding a
meeting

         The Action by Written Consent Amendment provides that, after this 2001
Annual Meeting, stockholder action may only be taken at annual and special
meetings of stockholders duly called and held. The Company's Board of Directors
believes that the Action by Written Consent Amendment will provide all
stockholders of the Company entitled to vote on a particular matter notice of,
and the opportunity to participate in, the determination of any proposed action
on such matter and the chance to take judicial or other action to protect their
interests. In addition, the Board of Directors believes that the elimination of
stockholder action by written consent is desirable to avoid untimely action in a
context that might not permit stockholders to have the full benefit of the
knowledge, advise and participation of the Company's management and Board of
Directors

         By prohibiting stockholder action by written consent, it may have the
effect of delaying, deferring or preventing a change of control of the Company
since stockholder action may only be taken at annual and special meeting of
stockholders duly called and held. The Board of Directors believes that this
prohibition will enhance the capacity of the Board of Directors to defend
against undesirable takeover attempts and, in the event of the sale of the
Company, would enhance the Board of Directors' ability to negotiate a
transaction that is in the stockholders' best interest. The proposed Action by
Written Consent Amendment is not being recommended in response to a pending or
threatened attempt to acquire control of the Company.

Vote Necessary to Approve the Proposal

         The affirmative vote of a majority of the shares outstanding is
necessary for approval of the amendment to the Company's Certificate of
Incorporation to remove the ability of stockholders to act by written consent.
Therefore, abstentions and broker non-votes effectively count as votes against
this proposal.


  THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ADOPTION OF THE PROPOSED
     AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO REMOVE THE ABILITY OF
                    STOCKHOLDERS TO ACT BY WRITTEN CONSENT.

                                  PROPOSAL FOUR

                  APPROVAL OF THE ISSUANCE OF UP TO 25 MILLION
                      SHARES OF THE COMPANY'S COMMON STOCK


Proposal

         In December 2000, the Company engaged an exclusive financial advisor
(the "Advisor") to assist the Company in implementing its business plan. In
relying on the recommendations of the Advisor, the Company is seeking to raise
additional capital through a private placement of the Company's preferred stock
(the "Private Placement"). Although the Board of Directors generally has the
authority to issue preferred stock from time to time, under the rules of the
American Stock Exchange, on which the Company's common stock is currently
listed, stockholder approval is required for certain private issuances of the
Company's common stock upon conversion of the preferred stock in an amount that
exceeds twenty percent (20%) of the outstanding common stock.

         Based on (i) the aggregate amount of the Company's required
expenditures for plant development, (ii) the aggregate amount of the Company's
required capital for financing potential acquisitions that the Company has and
may identify, (ii) the anticipated amount of the Company's working capital
requirements, (iii) the current market value of the Company's common stock, and
(iv) the fact that the Company may offer and sell securities convertible into
shares of common stock at a discount to the then prevailing market price, the
Company is seeking to offer and sell in the Private Placement a number of shares
of preferred stock that are convertible into shares of common stock that
constitute more than twenty percent (20%) of the Company's common stock issued
and outstanding prior to such offer and sale. The Board of Directors believes
that the Private Placement of the Company's preferred stock will provide the
Company with the appropriate additional capital in a timely manner for the above
described purposes.

         The following terms of the Private Placement are preliminary and
subject to change.

Dividends. A cumulative dividend of 7% will be payable in cash or in kind, at
the Company's option, semi-annually in arrears on each share of the Series B
Convertible Preferred Stock (Series B Preferred Stock).

Conversion Feature. Each holder of the Series B Preferred Stock will have the
right, at the holder's option, to convert any or all shares of the Series B
Preferred Stock into the Company's common stock at any time, at a conversion
price to be determined. In addition, the conversion price will have standard
weighted average anti-dilution protection in the event of the issuance of common
stock or common stock equivalents of the Company at a price less than the then
current conversion price.

Liquidation Preference. In the event of a liquidation of the Company, the
holders of the Series B Preferred Stock shall be entitled to receive in
preference to the holders of the Company's common stock an amount to be
determined plus cumulative dividends at the rate of 7% per annum.

Optional Redemption. If the average closing price, as reported on the American
Stock Exchange, equals or exceeds 300% of the conversion price for any 30
consecutive trading day period, the Company may, at its option, redeem the
Series B Preferred Stock , at a redemption price per share equal to the
liquidation value plus accrued and unpaid dividends. The holders of the Series B
Preferred Stock will be given notice of such redemption and will have the right
to convert the Series B Preferred Stock into the Company's common stock prior to
the date specified in the redemption notice.

Registration Rights. The Company shall file a registration statement under the
Securities Act of 1933 and any applicable state securities laws covering the
resale of the shares of common stock underlying the Series B Preferred Stock
within 30 days after the closing of the Private Placement. The Company agrees to
keep such registration statement effective until the shares of common stock
acquirable upon conversion of the Series B Preferred Stock are eligible for sale
pursuant to Rule 144 of the Securities Act without limitation as to volume. The
Company agrees to bear all fees and expenses incurred in connection with the
preparation and filing of the registration statement.


                                       22
<PAGE>   27


Voting Rights. The holders of the Series B Preferred Stock will not be entitled
to vote, except as required by law. Notwithstanding the foregoing, the
affirmative vote of a majority of the Series B Preferred Stock outstanding is
necessary for the issuance of securities senior to or on a parity with the
Series B Preferred Stock, the authorization or issuance of securities
convertible into such senior or parity securities, or the amendment of the
Company's Certificate of Incorporation so as to adversely affect the Series B
Preferred Stock, or waiver of any other covenants.

The Company will, however, only consummate the Private Placement after due
consideration by, and approval of, its Board of Directors, of such specific
terms. There can be no assurance that the Company will be successful in raising
capital pursuant to the Private Placement or otherwise.

         THIS PROXY STATEMENT DOES NOT CONSTITUTE AN OFFER TO SELL OR
SOLICITATION OF AN OFFER TO PURCHASE SECURITIES OF THE COMPANY. ANY OFFER OF
SECURITIES MADE BY THE COMPANY OR OTHER PERSON ON BEHALF OF THE COMPANY MAY BE
MADE ONLY PURSUANT TO MATERIALS AND OTHER OFFERING DOCUMENTS PREPARED BY THE
COMPANY AND DELIVERED TO QUALIFIED PURCHASERS EXPRESSLY FOR USE IN CONNECTION
WITH THE PRIVATE PLACEMENTS, AND ANY SUCH OFFER SHALL BE MADE IN COMPLIANCE
WITH, OR PURSUANT TO AN EXEMPTION FROM, SECTION 5 OF THE SECURITIES ACT OF 1933,
AS AMENDED.

Financial Advisor

         The Company's agreement with the Advisor (the "Advisory Agreement")
provides that the Advisor will assist the Company in implementing its business
plan, including advising the Company of various financing alternatives. The
Advisor's current recommendation to the Company is the Private Placement. This
recommendation is subject to certain conditions, including that there be no
material adverse change in the business of the Company or in general market
conditions.

         In addition to the financial advisory services rendered to the Company,
the Company has engaged the Advisor to act as the placement agent with respect
to the Private Placement. The Advisor and any co-placement agents will be
provided reasonable and customary compensation for their services in effecting
the Private Placement.

The Private Placement

         The Private Placement will consist of the offer and sale of the number
of shares of the Company's Series B Preferred Stock as may be necessary to
generate approximately $35 million in proceeds for the Company. The Series B
Preferred Stock offered and sold in the Private Placement will not possess
preemptive rights. The Series B Preferred Stock will be convertible into shares
of common stock at a conversion price per share to be determined. Further, the
Series B Preferred Stock offered and sold in the Private Placement, and its
underlying common stock, will not be registered under the Securities Act of
1933, as amended (the "Securities Act"), and accordingly such shares cannot be
offered and sold in the United States absent registration or an applicable
exemption from the registration requirements under the Securities Act. As a
result of the restrictions on transfer under the Securities Act on shares to be
issued in the Private Placement, it is possible that the Series B Preferred
Stock will be convertible into shares of common stock at some discount to the
then prevailing market price for common stock customary for private placements
of this nature. The final offering price for the Private Placement will be based
on market conditions and will be approved by the Company's Board of Directors.
In order to minimize any discount to market price necessary in the Private
Placement, the Company has agreed to file a registration statement under the
Securities Act with respect to the resale of the shares of common stock
acquirable upon conversion of the Series B Preferred Stock sold in the Private
Placement, and to use reasonable efforts to have such registration statement
declared effective as soon thereafter as possible.

         The Company's management will have broad discretion in applying the net
proceeds generated from the Private Placement. The Company expects, however, to
use the majority of the net proceeds to finance the construction of its first
plant in Wellsville, Ohio. The remainder will be used for general working
capital and potential acquisitions. Although a portion of the net proceeds are
anticipated to be used to fund one or more acquisitions, the Company has not
entered into any definitive agreements with respect to any potential
acquisitions at this time. Therefore, there can be no assurance that the Company
will successfully complete any acquisitions. If the Company is unable to
complete one or more potential acquisitions, such portion of the proceeds will
be available for use at the discretion of management.

Stockholder Approval Requirement

         Although the Board of Directors of the Company possesses the authority
under the Company's Certificate of Incorporation to approve the issuance of
preferred stock, Section 713 of the American Stock Exchange Listed Company Guide
generally requires stockholder approval in connection with the offer and sale of
common stock (or securities convertible into common stock) which equals twenty
percent (20%) or more of the shares of common stock outstanding before the offer
and sale at a price less than market value. The offer and sale of the Series B
Preferred Stock pursuant to the Private Placement will likely be convertible
into a number of shares of common stock that exceeds twenty percent (20%) of the
common stock outstanding prior to any such offer and sale and the conversion
price could be at a price that constitutes a discount to the then prevailing
market price of the Company's common stock. Accordingly, the Board of Directors
of the Company is seeking stockholder approval of the issuance of up to 25
million shares of the Company's common stock, issuable upon conversion of the
Company's Series B Preferred Stock, in order to complete the Private Placement,
if and when the Board of Directors approves the final terms of the Private
Placement. Such final terms will be determined by the Board of Directors in a
manner that it believes to be in the best interest of the Company and its
stockholders.

General Effect of Issuance of Common Stock on Existing Stockholders

         Adoption of this proposal and any issuance of common stock upon
conversion of the Series B Preferred Stock, would not affect the rights of the
holders of currently outstanding common stock, except for effects incidental to
increasing the outstanding number of shares of common stock, such as dilution of
earnings per share and voting rights of current holders of common stock.

Vote Necessary to Approve the Proposal

         Under the American Stock Exchange Rules, the affirmative vote of a
majority of the shares present in person or by proxy and entitled to vote at the
meeting is necessary for the approval of the issuance of up to 25 million shares
of the Company's common stock. For this purpose, an abstention will have the
same effect as a vote against the proposal to issue the Company's common stock.
Broker non-votes will not be counted as a vote either for or against the
proposal and will not be counted in determining the number of shares entitled to
vote on the proposal. If stockholders approve this proposal, no further
stockholder approval will be sought with respect to the Private Placement.


         THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE PROPOSAL TO
               APPROVE THE ISSUANCE OF UP TO 25 MILLION SHARES OF
                           THE COMPANY'S COMMON STOCK.


                                  PROPOSAL FIVE

                         APPROVAL OF AN AMENDMENT TO THE
                     1999 OMNIBUS STOCK AND INCENTIVE PLAN,
                             AS AMENDED AND RESTATED


Proposal

         The Company is requesting stockholder approval of an amendment to the
1999 Omnibus Stock and Incentive Plan, as amended and restated (the "1999
Plan"), for Probex Corp., which was adopted by stockholders on July 19, 2000.


                                       24
<PAGE>   29


         The Board of Directors believes that the Company's continued ability to
attract, motivate and retain experienced and highly qualified employees will
have a direct impact on the future success and profitability of the Company. The
purpose of the 1999 Plan is to advance the interests of the Company and increase
stockholder value by providing additional incentives to attract, retain and
motivate those qualified and competent employees, Directors and Consultants upon
whose efforts and judgment its success is largely dependent.

         The Board of Directors believes that an additional share reserve of
3,000,000 shares, which was approved by the Board in January 2001, is necessary
to enable the Company to attract, maintain and motivate qualified individuals
and industry experts. The ability of the Company to attract and maintain such
qualified individuals is critical to the Company during this period in which the
Company is evolving from a development corporation to an operational
corporation. In order to accomplish the foregoing, the Board of Directors has
approved, and recommends to the Company's stockholders that they approve an
amendment to the 1999 Plan which will increase the shares reserved under the
1999 Plan from 5,750,000 to 8,750,000. The Compensation Committee of the Board
of Directors has indicated that, if the amendment to the 1999 Plan is approved
by the stockholders, it intends to award, from the additional 3,000,000 shares,
incentive stock options and nonqualified stock options to purchase an aggregate
661,500 shares of common stock to certain directors and officers of the Company
as follows:

         than tenth anniversary of the date of grant.

(2)      Shares purchasable upon the exercise of options granted to directors
         vest immediately upon grant and expire as provided in the option, but
         not later than the tenth anniversary of the date of grant. The exercise
         price of these options was based upon the closing price of the
         Company's common stock as reported on the American Stock Exchange on
         the date of grant.

         If the amendment to the 1999 Plan to increase its available shares to
8,750,000 is not approved by the stockholders, the foregoing awards of options
will not be made and the Company will continue to operate under the original
July 19, 2000 version of the 1999 Plan, with its maximum of 5,750,000 shares,
and under which there currently are no shares available to be awarded.

         The principal features of the 1999 Plan are described below, but the
description is qualified in its entirety by reference to the full text of the
1999 Plan on file with Securities and Exchange Commission.

General Information

         The 1999 Plan is administered by the Compensation Committee of the
Board of Directors (the "Committee"), unless, and to the extent, the Board is
required to, or expressly elects to, itself act as the Committee. The 1999 Plan
provides for the granting of options, restricted stock awards and performance
awards. The Committee has the authority, consistent with the terms of the 1999
Plan: (i) to select the officers, directors, key employees of and consultants to
the Company to whom awards may from time to time be granted; (ii) to determine
whether and to what extent awards are to be granted to one or more eligible
persons; (iii) to determine the number of


                                       25
<PAGE>   30


shares to be covered by each such award granted; and (iv) to determine the terms
and conditions, not inconsistent with the terms of the 1999 Plan, of any award
granted (including, but not limited to, the agreed value and any restriction or
limitation, or any vesting acceleration or waiver of forfeiture restrictions,
based in each case on such factors as the Committee shall determine in its sole
discretion), and to amend or waive any such terms and conditions to the extent
not otherwise prohibited by the terms and conditions of the 1999 Plan.
Notwithstanding the forgoing, during any calendar year, beginning with the
calendar year 2000, the maximum number of shares for which an award may be
granted under the 1999 Plan to any person, whose compensation is subject to the
limitation on deductibility under Section 162(m) of the Code, is 1,100,000
shares. The Committee is authorized, in its sole discretion to interpret all of
the terms and provisions of the 1999 Plan, and will also make all other
determinations that it decides are necessary or desirable in the interpretation
and administration of the 1999 Plan.

         Under the 1999 Plan, as proposed to be amended, the maximum number of
shares of common stock that the Company may issue under awards will be
8,750,000, plus shares which are reacquired pursuant to the special share
repurchase plan. Under the share repurchase plan, which is expressly set forth
in the 1999 Plan, shares may be (i) repurchased by the Company in the open
market, or (ii) (at discretion of the Board of Directors) deemed as repurchased
from authorized but unissued, or treasury, shares at a deemed reacquisition
price equal to the closing price of the shares on the date of the deemed
reacquisition, provided that each actual purchase or deemed repurchase under the
share repurchase plan must be done only with the cash proceeds (not previously
used for such purpose) received by the Company with respect to exercised options
granted under the Plan. Also shares delivered to the Company in full or partial
payment of the exercise price of an option issued under the Plan will be
considered repurchased shares. Notwithstanding the foregoing, the aggregate
number of repurchased shares available under the Plan shall not exceed 75% of
the shares authorized for grant under the 1999 Plan at the time of reference,
and none of the repurchased shares can be subject to an incentive stock option.

Awards under the 1999 Plan

         Stock Options. A stock option ("Option"), which may be a non-qualified
or an incentive stock option, is the right to purchase a specified number of
shares of common stock at a price ("Option Price") fixed by the Committee. The
Option Price shall be any price determined by the Committee; provided, however,
that in the case of an incentive stock option, the Option Price per share may
not be less than the fair market value of a share on the date of grant. The
aggregate fair market value (determined as of the date of grant) of the shares
with respect to which an incentive stock option is exercisable for the first
time by an optionee during any calendar year may not exceed $100,000. Generally,
the Committee, in its sole discretion, may change the terms of an outstanding
award, provided it obtains the holder's approval where required by the terms of
the award or the 1999 Plan. The Committee is required to change the terms of
Options outstanding under the 1999 Plan, with respect to the Option Price or the
number of available shares subject to the Options, or both, when the Committee,
in its sole discretion, determines that such adjustments are appropriate by
reason of certain corporate transactions, such as the declaration of a stock
dividend or through any recapitalization resulting in a stock split-up,
combination or exchange of shares.

         The forfeitable (non-vested) portion of awards typically terminate
within a short period (i.e. 30 days) following a holder's termination of
employment by the Company. The period from termination of employment to
termination of the award is extended, in the case of an Option to: (i) 12
months, where the termination is by reason of death; (ii) 3 months, where the
termination is by reason of disability; and (iii) such other period as may be
provided in the Option. In all cases, Options will terminate not later than ten
years after their date of grant. The Committee, in its sole discretion, may
accelerate the date on which all or any portion of an otherwise unexercisable
Option may be exercised or a restriction will lapse. Additionally, the Committee
may condition the exercise of any Option upon the attainment of specified
performance goals or other factors as the Committee may determine in its sole
discretion.

         Incentive stock options shall not be granted to any person owning
directly (or indirectly pursuant to Section 425(d) of the Internal Revenue Code)
at the date of grant, stock representing more than 10% of the total combined
voting power of all classes of stock of the Company at the date of grant, unless
the Option Price is at least 110% of the fair market value on the date of grant
and the exercise period shall not exceed five (5) years from the date of grant.


                                       26
<PAGE>   31


         Non-Qualified Stock Options. Non-qualified stock options may be granted
under the 1999 Plan and shall contain such terms and provisions as shall be
determined by the Committee.

         Restricted Shares Award. A restricted shares award is an award of
common stock which is subject to a substantial risk of forfeiture during its
period of restriction, which period shall be selected by the Committee. The
restrictions on restricted shares shall lapse in whole, or in installments, over
the periods selected by the Committee; provided, however, that a complete lapse
always shall occur on or before the ninth anniversary of the date of grant.
Further, the Committee may accelerate the date on which restrictions lapse with
respect to any restricted shares.

         Each eligible person receiving a restricted shares award will have all
of the rights of a stockholder with respect to the restricted shares, such as
voting rights and the right to receive any dividends. Such restricted shares
will be registered in the holder's name and bear a restrictive legend disclosing
the restrictions; provided, however, such certificates shall be deposited with
the Company endorsed in blank with the necessary stock powers or other
instruments of assignment. During the restricted period, any distributions in
the form of shares, cash or other property (other than regular cash dividends)
made with respect to shares shall be subject to the same restrictions as the
corresponding shares, and such restrictions shall lapse at the same time the
restrictions on the corresponding shares(s) lapse; and all such restricted share
distributions will remain in the custody of the Company until that lapse date.
Restricted shares shall constitute issued and outstanding common stock for all
corporate purposes. Once the restrictions shall have lapsed, the stock
certificates and any related distributions, will be delivered to the entitled
holder.

         Performance Awards. The Committee may grant performance awards, which
may in the sole discretion of the Committee represent a common share or be
related to the increase in the value of a common share, or be contingent on the
Company's achievement of the specified performance measures during the
performance period, including, without limitation, performance shares,
convertible preferred stock, convertible debentures, exchangeable securities and
restricted share awards or options valued by reference to earnings per share or
subsidiary performance. Such performance awards may be granted alone, in
addition to, or in tandem with other awards made under, or outside, the 1999
Plan.

         The Committee is required to establish the performance measures for
each performance period, and such performance measures, and the duration of such
performance period, may differ with respect to each eligible person who receives
a performance award, or with respect to separate performance awards issued to
the same eligible person. Generally, the eligible person must remain employed by
the Company until the expiration of the performance period to be entitled to the
performance award; provided, however, that the Committee may specify in the
performance award agreement that a specified amount earned under the performance
award will be payable to the holder for the period between the date of grant and
date of termination of employment.

Other Provisions.

         In the event of either a change in control, or a potential change in
control, unless otherwise expressly provided by the Committee prior to such
event, (i) all awards, shall become fully exercisable, nonforfeitable, or the
restricted periods shall terminate, as the case may be, and (ii) the value of
all outstanding non-qualified stock options shall be cashed out on the basis of
the change in control price, effective as of the date of the change in control,
or on such other date as determined by the Committee.

         If at any time while the 1999 Plan is in effect or awards with respect
to available shares are outstanding, there shall be any increase or decrease in
the number of issued and outstanding shares through the declaration of a stock
dividend or through any recapitalization resulting in a stock split-up,
combination or exchange of shares, then and in such event appropriate
adjustments shall be made to the maximum number of available shares which may be
granted, and in the case of each award, the number of shares subject to the
award and (where applicable) the consideration to be paid by the holder in order
to acquire the shares. Except as otherwise provided in the 1999 Plan, no
adjustment shall be made to the available shares for shares of any class, or
securities convertible into shares of capital stock of any class, either in
connection with a direct sale to an unrelated party or for fair market value, or
upon the exercise of rights or warrants subscribed therefor, or upon conversion
of shares or obligations of the Company convertible into such shares or other
securities.

         No holder or other person shall be, or have any of the rights and
privileges of, the owner of the shares subject to an award unless and until
certificates representing such common stock shall have been issued and delivered
to such holder or other person. An award is not transferable except to the
holder's beneficiary, or (except for an incentive stock option), with the
consent of the Committee, to the holder's immediate family or to a charity.

Certain Federal Income Tax Consequences of Options

         For purposes of this discussion, the term "employer" shall be deemed to
include a person's employer and the Company for whom a non-employee performs
services.

         An employee to whom an incentive option which qualifies under Section
422 of the U.S. Internal Revenue Code of 1986, as amended (the "Code"), is
granted will not recognize income at the time of the grant or exercise of such
Option. No federal income tax deduction will be allowable to the employee's
employer upon the grant or exercise of such option. However, upon the exercise
of an incentive stock option, special alternative minimum tax rules apply for
the employee. Additionally, when the employee sells the shares attributable to
the exercise of an incentive stock option more than one year after the date of
exercise and more than two years after the date of grant (the "Minimum ISO
Period"), the employee will normally recognize a capital gain or loss equal to
the difference, if any, between the sales price of such shares and the exercise
price. If the employee does not hold such shares for the Minimum ISO Period,
when the employee sells such shares, the employee will recognize ordinary
compensation income equal (per share) to the excess of the exercise price over
the lesser of (i).the fair market value of the share on the date of exercise, or
(ii) the amount realized on the sale, and any amount of gain realized on the
sale which is in excess of the gain under (i) (if applicable) will be capital
gain. Subject to the applicable provisions of the Code and regulations
thereunder, including Section 162(m) of the Code, the employee's employer will
generally be entitled to a federal income tax deduction in the amount of
employee's ordinary compensation income.

         An individual to whom a non-qualified option is granted will not
recognize income at the time of the grant of such option. When such optionee
exercises such non-qualified option, the optionee will recognize ordinary
compensation income equal to the difference, if any, between the option price
paid and the fair market value, as of the date of the option exercise, of the
shares the optionee receives. The tax basis of such shares to such optionee will
be equal to the option price paid plus the amount includable in the optionee's
gross income, and the optionee's holding period for capital gain treatment upon
the sale of such shares will commence on the day on which the optionee exercises
the option and recognizes taxable income with respect to such shares. Subject to
the applicable provisions of the Code and regulations thereunder, including
those in Section 162(m) of the Code, the employer of such optionee will
generally be entitled to a federal income tax deduction with respect to the
exercise of such non-qualified option in an amount equal to the ordinary
compensation income recognized by the optionee. Any compensation includable in
the gross income of an employee with respect to the exercise of a non-qualified
option will be subject to appropriate federal income withholding and employment
taxes.

         The discussion above does not purport to be a complete analysis of all
potential tax consequences relevant to recipients of options or their employers
or to describe tax consequences based on particular circumstances and does not
address awards other than options. It is based on federal income tax law and
interpretational authorities as of the date of this proxy statement, which are
subject to change at any time.

                            CERTIFICATE OF AMENDMENT
                                     TO THE
                          CERTIFICATE OF INCORPORATION
                                       OF
                                  PROBEX CORP.


         Probex Corp., a corporation organized and existing under and by virtue
of the General Corporation Law of the State of Delaware (the "Corporation"),
does hereby certify:

         FIRST: That the Board of Directors of the Corporation duly adopted
resolutions proposing and declaring advisable the following amendment to the
Certificate of Incorporation of the Corporation:

         Section 5 shall be amended to read in its entirety as follows:

         "5. (a) The number of directors of the Corporation shall be fixed from
time to time in the manner provided by the Bylaws of the Corporation; provided,
however, that at any time there is only one stockholder of the Corporation, the
number of directors may not be less than one.

                  (b) The Board of Directors shall initially consist of six
members until changed in accordance with the Bylaws of the Corporation. There
shall be three classes of directors (each, a "Class"), known as Class I, Class
II and Class III. The initial Class I, Class II and Class III directors shall
serve in office as follows: Class I shall retire at the annual meeting of
stockholders to be held in year 2002, Class II shall retire at the annual
meeting of stockholders to be held in year 2003, and Class III shall retire at
the annual meeting to be held in year 2004. This annual sequence shall be
repeated thereafter. Each director in a Class shall be eligible for re-election
if nominated, and such director's seat shall be open for election of a director,
at the annual meeting of stockholders of the Corporation at which such Class
shall retire, to hold office for three years or until his successor is elected
or appointed.

         Any additional directors elected or appointed shall be elected or
appointed to such Class as will ensure that the number of directors in each
Class remains as nearly equal as possible, and if all Classes have an equal
number of directors or if one Class has one director more than the other two
Classes, then any additional directors elected or appointed shall be elected or
appointed to the Class that does not have more directors than any other Class
and is subject to election at an ensuing annual meeting before any other such
Class.

         Vacancies due to resignation, death, increases in the number of
directors, or any other cause shall be filled only by the Board of Directors
(unless there are no directors, in which case vacancies will be filled by the
stockholders) in accordance with the rule that each Class of directors shall be
as equal in number of directors as possible. Notwithstanding such rule, in the
event of any change in the authorized number of directors each director then
continuing to serve as such will nevertheless continue as a director of the
Class of which he or she is a member, until the expiration of his or her current
term or his earlier death, resignation or removal. If any newly created
directorship or vacancy on the Board of Directors, consistent with the rule that
the three Classes shall be as nearly equal in number as possible, may be
allocated to one or two or more Classes, then the Board of Directors shall
allocate it to that of the available Classes whose term of office is due to
expire at the earliest date following such allocation. When the Board of
Directors fills a vacancy, the director chosen to fill the vacancy shall be of
the same Class as the director he or she succeeds and shall hold office until
such director's successor shall have been elected and qualified or until such
director shall resign or shall have been removed. No reduction of the authorized
number of directors shall have the effect of removing any director prior to the
expiration of such director's term of office.

                  (c) Election of Directors need not be by written ballot unless

have any rights to cumulate votes in the election of directors."

Corporation pursuant to a resolution of its Board of Directors and duly adopted
by the majority of the shares outstanding entitled to vote thereon.

                                  PROBEX CORP.

                    AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

                                     CHARTER

GENERAL

         The role of the Audit Committee is to assist the Board of Directors in
fulfilling its oversight responsibilities by:

         o        Serving as an independent and objective party to monitor the
                  Corporations financial reporting process and internal control
                  system.

         o        Reviewing and appraising the audit efforts of the
                  Corporation's independent accountants.

         o        Providing an open avenue of communication among the
                  independent accountants, financial and senior management and
                  the Board of Directors.

COMPOSITION

         The Audit Committee shall consist of three or more directors as
determined by the Board, each of whom shall be independent directors; provided,
however, that so long as the Corporation shall meet the definition of "small
business issuer" for purposes of, and files reports under, Regulation S-B
promulgated by the Securities and Exchange Commission, the Audit Committee shall
consist of two or more members, a majority of whom shall be independent
directors. Each independent director shall be free from any relationship that,
in the opinion of the Board, would interfere with the exercise of his or her
independent judgment as a member of the Committee. In determining whether any
director is independent, the Board shall take into consideration the
requirements of the principal exchange or system on which the Corporation's
common stock is traded. Directors who are affiliates of the Company, or officers
or employees of the Company or of its subsidiaries, will not be considered
independent. Notwithstanding the first sentence of this paragraph, until June
14, 2001, the Committee may consist of two or more directors meeting the
qualifications of this section.

         All members of the Committee must be able to read and understand
fundamental financial statements, including a corporation's balance sheet,
income statement, and cash flow statement or become able to do so within a
reasonable period of time after his or her appointment to the Committee, and at
least one member of the Committee is to have past employment experience in
finance or accounting, requisite professional certification in accounting, or
any other comparable experience or background which results in the member's
financial sophistication, including being or having been a chief executive
officer, chief financial officer or other senior officer with financial
oversight responsibilities; provided, however, that so long as the Corporation
shall continue to be a "small business issuer," the requirements of the
foregoing paragraph shall not be mandatory upon the Corporation.


                                      C-1
<PAGE>   38


         The members of the Committee are to be elected by the Board and shall
serve until their successors are duly elected and qualified. Unless a Chair is
elected by the full Board, the members of the Committee may designate a Chair by
majority vote of the full Committee membership.

MEETINGS

         The Committee shall hold regular meetings as may be necessary and
special meetings as may be called by the Chairman of the Committee. As part of
its job to foster open communication, the Committee should meet at least
annually with management and the independent accountants in separate executive
sessions to discuss any matters that the Committee or either of these groups
believe should be discussed privately. In addition, the Committee or its Chair
should meet with the independent accountants and management quarterly to review
the Corporation's financial statements.

RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS

         The Corporation's independent accountants are to be ultimately
accountable to the Board and the Committee, and the Committee and the Board
shall have the ultimate authority and responsibility to select, evaluate and,
where appropriate, replace the independent accountants (or nominate the outside
auditor to be proposed for shareholder approval in any proxy statement).

RESPONSIBILITIES AND DUTIES

         To fulfill its responsibilities and duties the Audit Committee shall:

Documents/Reports Review

1.       Review and assess the adequacy of this Charter at least annually, and
         otherwise as conditions dictate.

2.       Review the Corporation's annual financial statements and any reports or
         other financial information submitted to the Securities and Exchange
         Commission or the public, including any certification, report, opinion,
         or review rendered by the independent accountants.

3.       Review with financial management and the independent accountants the
         Corporation's filings with the Securities and Exchange Commission on
         Form10-Q or Form 10-QSB, as applicable, prior to their filing or prior
         to the release of earnings. The Chair of the Committee may represent
         the entire Committee for purposes of this review.

Independent Accountants

Recommend to the Board the selection of the independent accountants, considering
independence and effectiveness, and approve the fees and other compensation to
be paid to the independent accountants.

4.       On an annual basis, obtain from the independent accountants, and review
         and discuss with the independent accountants, a formal written
         statement delineating all relationships the independent accountants
         have with the Corporation, consistent with Independence Standards Board
         Standard 1, and actively engage in a dialogue with the independent
         accountants with respect to any disclosed relationships or services
         that may impact the objectivity and independence of the independent
         accountants.

5.       Recommend to the Board any appropriate action to oversee the
         independence of the independent accountants.

6.       Review the performance of the independent accountants and approve any
         proposed discharge of the independent accountants when circumstances
         warrant.

7.       Periodically consult with the independent accountants out of the
         presence of management about internal controls and the fullness and
         accuracy of the Corporation's financial statements.


                                      C-2
<PAGE>   39


Financial Reporting Processes

8.       In consultation with the independent accountants, review the integrity
         of the organization's financial reporting processes, both internal and
         external.

9.       Consider the independent accountant's judgments about the quality and
         appropriateness of the Corporation's accounting principles as applied
         in its financial reporting.

10.      Consider and approve, if appropriate, major changes to the
         Corporation's auditing and accounting principles and practices as
         suggested by the independent accountants or management.

11.      Establish regular and separate reporting to the Committee by each of
         management and the independent accountants regarding any significant
         judgments made in management's preparation of the financial statements
         and the view of each as to appropriateness of such judgments.

12.      Following completion of the annual audit, review separately with each
         of management and the independent accountants any significant
         difficulties encountered during the course of the audit, including any
         restrictions on the scope of work or access to required information.

13.      Review any significant disagreement among management and the
         independent accountants in connection with the preparation of the

indicated:

         (a) "AFFILIATE" means any entity other than the Parent that is
designated by the Board as a participating employer under the Plan, provided

power of all classes of stock of such entity or at least 20% of the ownership
interests in such entity.

         (b) "AWARD" shall mean either an Option, a Restricted Share Award, or a
Performance Award, except that where it shall be appropriate to identify the
specific type of Award, reference shall be made to the specific type of Award.

         (c) "AVAILABLE SHARES" shall mean, at each time of reference, the total
number of Shares described in SECTION 3 with respect to which the Committee may

         (e) "CAUSE" shall mean either (a) an Optionee's material failure or

involuntarily terminated from employment based upon his commission of any of the
following:

                  (i) an intentional act of fraud, embezzlement or theft in
         connection with his duties or in the course of his employment with the
         Company;

                  (ii) intentional wrongful damage to property of the Company or
         any other willful gross misconduct that causes material economic harm
         to the Company or that brings substantial discredit to the Company's
         reputation;

         confidential information of the Company;

         involving personal profit.

         For the purpose of this Agreement, no act, or failure to act, on the
part of the Optionee shall be deemed "intentional" unless the Board of Directors
finds, in its sole discretion, that the act or failure to act was done, or
omitted to be done, by the Optionee in other than good faith and without
reasonable belief that his action or omission was in the best interest of the
Company. Any determination that an Optionee has been terminated For Cause shall
be made by the Board of Directors in its sole and absolute discretion.

voting power of the Parent's outstanding voting securities on the Effective
Date, or the acquisition of beneficial ownership of an additional 6% of the
voting power of the Parent's outstanding voting securities by any person or
group who beneficially owned at least 15% of the voting power of the Parent's
outstanding voting securities on the Effective Date; provided, however, that
notwithstanding the foregoing, an acquisition shall not be described hereunder
if the acquiror is (x) a trustee or other fiduciary holding securities under an
employee benefit plan of the Company and acting in such capacity, (y) a
wholly-owned subsidiary of the Parent or a corporation owned, directly or

corporation in the unbroken chain, owns stock possessing 50% or more of the
total combined voting power of all classes of stock in one of the other
corporations in such unbroken chain.

         (qq) "1933 ACT" shall mean the Securities Act of 1933, as amended.

         (rr) "1934 ACT" shall mean the Securities Exchange Act of 1934, as
amended.

3.       AWARD OF AVAILABLE SHARES.

         (a) As of the Effective Date, 2,750,000 Shares shall automatically, and
without further action, become Available Shares, and as of March 30, 2000, on
additional 3,000,000 Shares shall automatically, and without further action,
become Available Shares. Thereafter, the number of Available Shares shall be
increased automatically by the number of Reacquired Shares. To the extent any
Award shall terminate, expire or be canceled, or the Award shall be paid in
cash, the Available Shares subject to such Award (or with respect to which the
Award is measured), shall remain Available Shares.

         (b) Notwithstanding the forgoing, Incentive Stock Options may not be
issued in whole or in part with respect to Reacquired Shares; provided, further,
that where an Award other than an Incentive Stock Option is granted at a time
when Reacquired Shares are available for grant under the Plan (i.e. are not
subject to a previous grant), for purposes of this SECTION 3(b) the Award shall
be deemed granted with respect to Reacquired Shares, and to the extent an Award
granted with respect to Reacquired Shares shall terminate, expire or be
canceled, or the Award shall be paid in cash, the Available Shares subject to
such Award (or with respect to which the Award is measured), shall remain
Available Shares and continue to be considered Reacquired Shares for purposes of
this SECTION 3(b). Further, notwithstanding


                                        6
<PAGE>   53



any provision hereof to the contrary, no person whose compensation is subject to
the limitations on deductibility under Section 162(m) of the Code shall be
eligible to receive Awards during any Plan Year with respect to more than
1,100,000 shares. The Administrator shall maintain records sufficient to carry
out the purposes of this SECTION 3(b).

4.       CONDITIONS FOR GRANT OF AWARDS.

         (a) Without limiting the generality of the provisions hereof which deal
specifically with each form of Award, Awards shall only be granted to such one
or more Eligible Persons as shall be selected by the Committee; provided
further, and without limitation, that nothing herein shall be deemed to prohibit
the Committee from granting an Award contingent on the Eligible Person receiving
the Award surrendering an existing Award.

         (b) In granting Awards, the Committee shall take into consideration the
contribution the Eligible Person has made or may be reasonably expected to make
to the success of the Company and such other factors as the Committee shall
determine. The Committee shall also have the authority to consult with and
receive recommendations from officers and other personnel of the Company with
regard to these matters. The Committee may from time to time in granting Awards
under the Plan prescribe such other terms and conditions concerning such Awards
as it deems appropriate, including, without limitation, relating an Award to
achievement of specific goals established by the Committee or to the continued
employment of the Eligible Person for a specified period of time, provided that
such terms and conditions are not inconsistent with the provisions of this Plan.

         (c) Incentive Stock Options may be granted only to Employees, and all
other Awards may be granted to either Employees, Consultants or Outside
Directors.

         (d) The Plan shall not confer upon any Holder any right with respect to
continuation of employment by, or consulting relationship with, the Company, nor
shall it interfere in any way with his right or the Company's right to terminate
his employment, consulting relationship or Directorship at any time, nor shall
the reference to "Company" confer an employment relationship on a Consultant.

         (e) The Awards granted to Eligible Persons shall be in addition to
regular salaries, pension, life insurance or other benefits related to their
service to the Company. Neither the Plan nor any Award granted under the Plan
shall confer upon any person any right to continuance of employment by the
Company; and provided, further, that nothing herein shall be deemed to limit the
ability of the Company to enter into any other compensation arrangements with
any Eligible Person.

         (f) The Committee shall determine in each case whether periods of
military or government service shall constitute a continuation of employment for
the purposes of this Plan or any Award.

         (g) Notwithstanding any provision hereof to the contrary, each Award
which in whole or in part involves the issuance of Available Shares may provide
for the issuance of


                                        7
<PAGE>   54



such Available Shares for consideration consisting of such consideration as the
Committee may determine, including (without limitation) as compensation for past
services rendered.

5.       GRANT OF OPTIONS.

         (a) The Committee may grant to Optionees from time to time Options
alone, in addition to, or in tandem with, other Awards granted under the Plan
and/or cash Awards made outside of the Plan, to purchase some or all of the
Available Shares. An Option granted hereunder shall be either an Incentive Stock
Option or a Non-qualified Stock Option, shall be evidenced by a written
agreement that shall contain such provisions as shall be selected by the
Committee, which may incorporate the terms of this Plan by reference, and which
clearly shall state whether it is (in whole or in part) an Incentive Stock
Option or a Non-qualified Stock Option.

         (b) The aggregate Fair Market Value (determined as of the Date of
Grant) of the Available Shares with respect to which any Incentive Stock Option
is exercisable for the first time by an Optionee during any calendar year under
the Plan and all such plans of the Company (as defined in Section 425 of the
Code) shall not exceed $100,000.

         (c) A Non-qualified Stock Option shall not be transferable by the
Holder without the prior written consent of the Committee other than (i)
transfers by the Holder to a member of his or her Immediate Family or a trust
for the benefit of the optionee or a member of his or her Immediate Family, or
(ii) transfers by will or by the laws of descent and distribution. An Incentive
Stock Option shall not be transferable by the Holder otherwise than by will or
by the laws of descent and distribution. All Options shall be exercisable,
during the Holder's lifetime, only by the Holder.

         (d) In the case of a Non-qualified Stock Option or a Holder who elects
to make a disqualifying disposition (as defined in Section 422(a)(1) of the
Code) of Shares acquired pursuant to the exercise of an Incentive Stock Option,
the Committee may provide that, at such time as the Company files an income tax
return on which it shows taxable income, or upon the later exercise of the
Non-qualified Stock Option or disqualifying disposition of an Incentive Stock
Option, the Optionee will be paid a cash bonus in an amount equal to some or all
of the federal and state, if any, income tax incurred (or deemed incurred) by
the Holder (i) as a result of such exercise or disqualifying disposition, and
(ii) as a result of the payment of such cash bonus; and provided, further, that
the amount of such cash bonus may be expressed in the case of an Non-Qualified
Stock Option as a percentage of the Spread on the date of exercise, and may be
expressed in the case of a disqualifying disposition as a percentage of the
ordinary income reportable as a result of such disqualifying disposition;
provided, further, that in each case the Committee shall determine the
percentage in its sole discretion and separately with respect to each Optionee
and each Option.

         (e) If the Option agreement so provides at Date of Grant or (except in
the case of an Incentive Stock Option) is amended after Date of Grant and prior
to exercise to so provide (with the Holder's consent), the Committee may require
that all or part of the Shares to be issued with respect to the Spread take the
form of Restricted Stock, which shall be


                                        8
<PAGE>   55

valued on the date of exercise on the basis of the Fair Market Value of such
Restricted Stock determined without regard to the transferability and forfeiture
restrictions involved.

         (f) Without limitation, the Committee may condition the exercise of any
Option upon the attainment of specified performance goals or other factors as
the Committee may determine in its sole discretion. Unless specifically provided
to the contrary in the Option agreement, any such performance conditioned Option
shall vest twelve (12) months prior to its expiration if the conditions to
exercise have not theretofore been satisfied.

6.       OPTION PRICE.

         (a) The Option Price shall be any price determined by the Committee;
provided, however, that in the case of an Incentive Stock Option, the Option
Price shall not be less than one hundred percent (100%) of the Fair Market Value
per Share (as reasonably determined in the sole discretion of the Committee) on
the Date of Grant.

         (b) Unless further limited by the Committee in any Option, the Option
Price shall be paid solely in cash, by certified or cashier's check, by wire
transfer, by money order, with Shares (but only to the extent expressly
permitted under the terms of the Option), or by a combination of the above;
provided, however, that the Committee, in its discretion, may accept a personal
check in full or partial payment. Without limitation, in the Committee's sole
discretion (but only to the extent expressly permitted under the terms of the
Option), the Option Price of an Option can be paid in full or in part by the
surrender of Vested Shares subject to the Option or to any other Award
hereunder. If the Option Price is permitted to be, and is, paid in whole or in
part with Shares, the value of the Share(s) surrendered shall be their Fair
Market Value on the date they are delivered to the Company.

7.       EXERCISE OF OPTIONS. An Option shall be deemed exercised when (i) the
Committee has received written notice of such exercise in accordance with the
terms of the Option, and (ii) full payment of the aggregate Option Price of the
Available Shares as to which the Option is exercised has been made. Separate
stock certificates shall be issued by the Parent for any Available Shares
acquired as a result of exercising an Incentive Stock Option and a Non-
qualified Stock Option.

8.       EXERCISABILITY OF OPTIONS.

         (a) Each Option shall become exercisable in whole or in part and
cumulatively, and shall expire, according to the terms of the Option to the
extent not inconsistent with the express provisions of this Plan; provided,
further and without limitation, that each Option may have a different maximum
period of exercisability prior to its expiration date.

         (b) The Committee, in its sole discretion, may accelerate the date on
which all or any portion of an otherwise unexercisable Option may be exercised
or a restriction will lapse.


                                        9
<PAGE>   56



9.       TERMINATION OF OPTION PERIOD.

         (a) As provided in SECTION 5, and without limitation, each Option shall
be evidenced by an agreement that may contain any provisions selected by the
Committee; provided, however, that in each case, unless terminated earlier under
the express terms of the Option, the unexercised portion of an Option shall
automatically and without notice terminate and become null and void on the
earlier of (i) the date that Optionee ceases to be employed by the Company, if
such cessation is for Cause, (ii) the anniversary of the date of the Optionee's
cessation of employment by reason of Optionee's death, (iii) the three month
anniversary of the date of Optionee's cessation of employment by reason of
Optionee's Disability, (iv) the tenth (10th) anniversary of the Date of Grant;
and (v) solely in the case of an Incentive Stock Option, three months after the
date that Optionee ceases to be employed by the Company regardless of the reason
therefor, other than a cessation by reason of death, in which case the date of
termination may be extended under the terms of the Incentive Stock Option
agreement.

         (b) Notwithstanding any provision of SECTION 15(a) to the contrary, if
provided in an Option, the Committee may, by giving written notice
("CANCELLATION NOTICE"), cancel, effective upon the date of the consummation of
any of the transactions described in SUBSECTION 15(a), all or any portion of
such Option which remains unexercised on such date. Such Cancellation Notice
shall be given a reasonable period of time (but not less than 15 days) prior to
the proposed date of such cancellation, and may be given either before or after
shareholder approval of such corporate transaction.

10.      INCENTIVE STOCK OPTIONS FOR 10% SHAREHOLDER. Notwithstanding any other
provisions of the Plan to the contrary, an Incentive Stock Option shall not be
granted to any person owning directly (or indirectly through attribution under
Section 425(d) of the Code) at the Date of Grant, stock possessing more than 10%
of the total combined voting power of all classes of stock of the Company (as
defined in Section 425 of the Code) at the Date of Grant, unless the Option
Price of such Incentive Stock Option is at least 110% of the Fair Market Value
on the Date of Grant of the Available Shares subject to such Incentive Stock
Option, and the period during which the Incentive Stock Option may be exercised
does not exceed five (5) years from the Date of Grant.

11.      NON-QUALIFIED STOCK OPTIONS. Non-qualified Stock Options may be granted
hereunder and shall contain such terms and provisions as shall be determined by
the Committee, except that each such Non-qualified Stock Option (i) must be
clearly designated as a Non-qualified Stock Option; (ii) may be granted for
Available Shares which become exercisable in excess of the limits contained in
SUBSECTION 5(b); and (iii) shall not be subject to SECTION 10 hereof. If both
Incentive Stock Options and Non-qualified Stock Options are granted to an
Optionee, the right to exercise, to the full extent thereof, Options of either
type shall not be contingent in whole or in part upon the exercise of, or
failure to exercise, Options of the other type.


                                       10
<PAGE>   57



12.      RESTRICTED SHARE AWARDS.

         (a) Each Restricted Share Award shall be evidenced by an agreement that
may contain any provisions selected by the Committee, and not expressly in
conflict with a provision of the Plan. Except as otherwise provided in the
express terms and conditions of each Restricted Share Award, the Eligible Person
receiving the Restricted Share Award shall have all of the rights of a
shareholder with respect to such Restricted Shares including, but not limited
to, voting rights and the right to receive any dividends paid, subject only to
the retention provisions of the Restricted Share Distributions.

         (b) The Restrictions on Restricted Shares shall lapse in whole, or in
installments, over whatever Restricted Period shall be selected by the
Committee; provided, however, that a complete lapse of Restrictions always shall
occur on or before the 9th anniversary of the Date of Grant.

         (c) The Committee may accelerate the date on which Restrictions lapse
with respect to any Restricted Shares.

         (d) During the Restricted Period, the certificates representing the
Restricted Shares, and any Restricted Share Distributions, shall be registered
in the Holder's name and bear a restrictive legend disclosing the Restrictions,
the existence of the Plan, and the existence of the applicable agreement
granting such Restricted Share Award. Such certificates shall be deposited by
the Holder with the Company, together with stock powers or other instruments of
assignment, each endorsed in blank, which will permit the transfer to the
Company of all or any portion of the Restricted Shares, and any assets
constituting Restricted Share Distributions, which shall be forfeited in
accordance with the applicable agreement granting such Restricted Share Award.
Restricted Shares shall constitute issued and outstanding Common Stock for all
corporate purposes and the Holder shall have all rights, powers and privileges
of a Holder of unrestricted Shares except that the Holder will not be entitled
to delivery of the stock certificates until all Restrictions shall have
terminated, and the Company will retain custody of all related Restricted Share
Distributions (which will be subject to the same Restrictions, terms, and
conditions as the related Restricted Shares) until the conclusion of the
Restricted Period with respect to the related Restricted Shares; and provided,
further, that any Restricted Share Distributions shall not bear interest or be
segregated into a separate account but shall remain a general asset of the
Company, subject to the claims of the Company's creditors, until the conclusion
of the applicable Restricted Period; and provided, finally, that any material
breach of any terms of the agreement granting the Restricted Share Award, as
reasonably determined by the Committee will cause a forfeiture of both
Restricted Shares and Restricted Share Distributions.

13.      PERFORMANCE AWARDS.

         (a) The Committee may grant Performance Awards, which may in the sole
discretion of the Committee represent a Share or be related to the increase in
value of a Share, or be contingent on the Company's achievement of the specified
performance measures during the Performance Period, including, without
limitation, performance shares, convertible


                                       11
<PAGE>   58



preferred stock, convertible debentures, exchangeable securities and Restricted
Share Awards or Options valued by reference to earnings per Share or Subsidiary
performance, may be granted either alone, in addition to, or in tandem with,
other Awards and cash awards made outside of the Plan. The Committee shall
establish the performance measures for each Performance Period, and such
performance measures, and the duration of any Performance Period, may differ
with respect to each Eligible Person who receives a Performance Award, or with
respect to separate Performance Awards issued to the same Eligible Person. The
performance measures, the medium of payment, the Performance Period(s) and any
other conditions to the Company's obligation to pay such Performance Award in
full or in part, shall be set forth in the written agreement evidencing each
Performance Award.

         (b) Unless otherwise expressly provided in the agreement evidencing the
Performance Award, the Holder of the Performance Award must remain employed by
the Company until the end of the Performance Period in order to be entitled to
any payment under such Performance Award; provided, however, that the Committee
expressly may provide in the agreement granting such Performance Award that such
Holder may become entitled to a specified portion of the amount earned under
such Performance Award based on one or more specified period(s) of time between
the Date of Grant of such Performance Award and such Holder's termination of
employment by the Company prior to the end of the Performance Period.

14.      ACCELERATION.

         (a) In the event the Holder's termination of employment with the
Company is by reason of the Holder's death, all Awards granted to the Holder
shall become fully exercisable, nonforfeitable, or the Restricted Period shall
terminate as the case may be (hereafter, in this SECTION 14, such Award shall be
"accelerated").

         (b) In the event of either a Change in Control, or a Potential Change
in Control, unless otherwise expressly provided by the Committee prior to such
event, (i) all Awards, shall become fully exercisable, nonforfeitable, or the
Restricted Period shall terminate, as the case may be (hereafter, in this
SECTION 14, such Award shall be "accelerated") and (ii) the value of all
outstanding Non-qualified Stock Options, Restricted Stock, and Outside Director
Options shall be cashed out on the basis of the Change in Control Price,
effective as the date of the Change in Control, or on such other date as the
Committee may determine prior to the Change in Control.

         (c) Notwithstanding any provisions hereof to the contrary, if an Award
is accelerated under SUBSECTION 14(a) or (b), the portion of the Award which is
accelerated is limited to that portion which can be accelerated without causing
the Holder to have an "excess parachute payment" as determined under Section
280G of the Code, determined by taking into account all of the Holder's
"parachute payments" determined under Section 280G of the Code, all as
reasonably determined by the Committee.

<PAGE>   59

15.      ADJUSTMENT OF AVAILABLE SHARES.

         (a) If at any time while the Plan is in effect or Awards with respect
to Available Shares are outstanding, there shall be any increase or decrease in
the number of issued and outstanding Shares through the declaration of a stock
dividend or through any recapitalization resulting in a stock split-up,
combination or exchange of Shares, then and in such event:

                     (i) appropriate adjustment shall be made in the maximum
         number of Available Shares which may be granted under SECTION 3, and in
         the Available Shares which are then subject to each Award, so that the
         same proportion of the Parent's issued and outstanding Common Stock
         shall continue to be subject to grant under SECTION 3, and to such
         Award, and

                     (ii) in addition, and without limitation, in the case of
         each Award (including, without limitation, Options) which requires the
         payment of consideration by the Holder in order to acquire Shares, an
         appropriate adjustment shall be made in the consideration (including,
         without limitation the Option Price) required to be paid to acquire the
         each Share, so that (i) the aggregate consideration to acquire all of
         the Shares subject to the Award remains the same and, (ii) so far as
         possible (and without disqualifying an Incentive Stock Option) as
         reasonably determined by the Committee in its sole discretion, the
         relative cost of acquiring each Share subject to such Award remains the
         same.

         (b) The Committee may change the terms of Options outstanding under
this Plan, with respect to the Option Price or the number of Available Shares
subject to the Options, or both, when, in the Committee's judgment, such
adjustments become appropriate by reason of a corporate transaction (as defined
in Treasury Regulation ss. 1.425-1(a)(1)(ii)); provided, however, that if by
reason of such corporate transaction an Incentive Stock Option is assumed or a
new option is substituted therefore, the Committee may only change the terms of
such Incentive Stock Option such that (i) the excess of the aggregate Fair
Market Value of the Shares subject to option immediately after the substitution
or assumption, over the aggregate option price of such Shares, is not more than
the excess of the aggregate Fair Market Value of all Available Shares subject to
the Option immediately before such substitution or assumption over the aggregate
Option Price of such Available Shares, and (ii) the new option, or the
assumption of the old Incentive Stock Option does not give the Optionee
additional benefits which he did not have under the old Incentive Stock Option.

         (c) Except as otherwise expressly provided herein, the issuance by the
Parent of shares of its capital stock of any class, or securities convertible
into shares of capital stock of any class, either in connection with direct sale
to an unrelated party or for Fair Market Value, or upon the exercise of rights
or warrants to subscribe therefor, or upon conversion of shares or obligations
of the Parent convertible into such shares or other securities, shall not
affect, and no adjustment by reason thereof shall be made with respect to
Available Shares subject to Awards granted under the Plan.


                                       13

<PAGE>   60

         (d) Without limiting the generality of the foregoing, the existence of
outstanding Awards with respect to Available Shares granted under the Plan shall
not affect in any manner the right or power of the Parent to make, authorize or
consummate (1) any or all adjustments, recapitalizations, reorganizations or
other changes in the Parent's capital structure or its business; (2) any merger
or consolidation of the Parent; (3) any issue by the Parent of debt securities,
or preferred or preference stock which would rank above the Available Shares
subject to outstanding Awards; (4) the dissolution or liquidation of the Parent;
(5) any sale, transfer or assignment of all or any part of the assets or
business of the Company; or (6) any other corporate act or proceeding, whether
of a similar character or otherwise.

16.      TRANSFERABILITY OF AWARDS. Each Award shall provide that such Award
shall not be transferable by the Holder otherwise than by will or the laws of
descent and distribution, or, if so provided in the Award and approved in
writing by the Committee (in its sole discretion), (a) that such Award is
transferable, in whole or in part, without payment of consideration, to members
of the Holder's Immediate Family, to trusts for such Immediate Family members,
or to partnerships whose only partners are such Immediate Family members, or (b)
to a person or other entity for which the Holder is entitled to a deduction for
a "charitable contribution" under Section 170(a)(i) of the Code (provided, in
each such case that no further transfer by any such permitted transferee(s)
shall be permitted).

17.      ISSUANCE OF SHARES. No Holder or other person shall be, or have any of
the rights or privileges of, the owner of Shares subject to an Award unless and
until certificates representing such Common Stock shall have been issued and
delivered to such Holder or other person. As a condition of any issuance of
Common Stock, the Committee may obtain such agreements or undertakings, if any,
as the Committee may deem necessary or advisable to assure compliance with any
such law or regulation including, but not limited to, the following:

                     (i) a representation, warranty or agreement by the Holder
         to the Parent, at the time any Shares are transferred, that he is
         acquiring the Shares to be issued to him for investment and not with a
         view to, or for sale in connection with, the distribution of any such
         Shares; and

                     (ii) a representation, warranty or agreement to be bound by
         any legends that are, in the opinion of the Committee, necessary or
         appropriate to comply with the provisions of any securities law deemed
         by the Committee to be applicable to the issuance of the Shares and are
         endorsed upon the Share certificates.

         Share certificates issued to the Holder receiving such Shares who are
parties to any shareholders agreement or any similar agreement shall bear the
legends contained in such agreements. Notwithstanding any provision hereof to
the contrary, no Shares shall be required to be issued with respect to an Award
unless counsel for the Parent shall be reasonably satisfied that such issuance
will be in compliance with applicable Federal or state securities laws.

18.      ADMINISTRATION OF THE PLAN.

         (a) The Plan shall be administered by the Committee and, except for the
powers reserved to the Board in SECTION 21 hereof, the Committee shall have all
of the administrative powers under Plan. If a Committee is not appointed by the
Board at the time of reference, the Plan shall be administered by the Board and
all references herein to the Committee shall refer to the Board. Notwithstanding
the forgoing, no member of the Committee may be present at discussions
concerning, or vote on, matters which materially affect his Award.
Notwithstanding any provision of the Plan to the contrary, the Board, exclusive
of the non- employee Directors, shall act exclusively as the Committee with
respect to all matters relating to the granting of, and administration of the
Plan with respect to, Awards to non-employee Directors.

         (b) The Committee, from time to time, may adopt rules and regulations
for carrying out the purposes of the Plan and, without limitation, may delegate
all of what, in its sole discretion, it determines to be ministerial duties to
an officer of the Parent. The determinations under, and the interpretations of,
any provision of the Plan or an Award by the Committee shall, in all cases, be
in its sole discretion, and shall be final and conclusive.

         (c) Any and all determinations and interpretations of the Committee
shall be made either (i) by a majority vote of the members of the Committee at a
meeting duly called, with at least 3 days prior notice and a general explanation
of the subject matter given to each member, or (ii) without a meeting, by the
written approval of all members of the Committee.

         (d) No member of the Committee shall be liable for any action taken or
omitted to be taken by him or by any other member of the Committee with respect
to the Plan, and to the extent of liabilities not otherwise insured under a
policy purchased by the Company, the Company does hereby indemnify and agree to
defend and save harmless any member of the Committee with respect to any
liabilities asserted or incurred in connection with the exercise and performance
of their powers and duties hereunder, unless such liabilities are judicially
determined to have arisen out of such member's gross negligence, fraud or bad
faith. Such indemnification shall include attorney's fees and all other costs
and expenses reasonably incurred in defense of any action arising from such act
of commission or omission. Nothing herein shall be deemed to limit the Company's
ability to insure itself with respect to its obligations hereunder.

         (e) In particular, and without limitation, the Committee shall have the
authority, consistent with the terms of the Plan:

                  (i) to select the officers, key employees of and consultants
         to the Company to whom Awards may from time to time be granted
         hereunder;

                  (ii) to determine whether and to what extent Awards are to be
         granted hereunder to one or more eligible persons;


                                       15

<PAGE>   62

                  (iii) to determine the number of Shares to be covered by each
         such Award granted hereunder;

                  (iv) to determine the terms and conditions, not inconsistent
         with the terms of the Plan, of any Award granted hereunder (including,
         but not limited to, the Agreed Value and any restriction or limitation,
         or any vesting acceleration or waiver of forfeiture restrictions, based
         in each case on such factors as the Committee shall determine, in its
         sole discretion); and to amend or waive any such terms and conditions
         to the extent permitted by the Plan;

                  (v) to determine whether and under what circumstances an
         Option may be settled in cash or Restricted Shares instead of Shares;

                  (vi) to determine whether, to what extent, and under what
         circumstances Awards under the Plan are to be made, and operate, on a
         tandem basis vis-a-vis other Awards under the Plan and/or cash awards
         made outside of the Plan;

                  (vii) to determine whether and to what extent, and under what
         circumstances Shares and other amounts payable with respect to an Award
         shall be deferred either automatically or at the election of the Holder
         (including providing for and determining the amount (if any) of any
         deemed earnings on any deferred amount during any deferral period); and

                  (viii) to determine whether to require payment of tax
         withholding requirements in Shares and to impose any holding period
         required to satisfy Section 16 under the Exchange Act.

         (f) The Committee shall have the authority to adopt, alter, and repeal
such rules, guidelines, and practices governing the Plan as it shall, from time
to time, deem advisable; to interpret the terms and provisions of the Plan and
any Award issued under the Plan (and any agreements relating thereto); and to
otherwise supervise the administration of the Plan; provided, however, that to
the extent that this Plan otherwise requires the approval of the Board or the
shareholders of the Parent, all decisions of the Committee shall be subject to
such Board or shareholder approval. Subject to the foregoing, and without
limitation, all decisions made by the Committee pursuant to the provisions of
the Plan shall be made in the Committee's sole discretion and shall be final and
binding on all persons, including the Company and Holders.

19.      TAX WITHHOLDING. On or immediately prior to the date on which a payment
is made to a Holder hereunder or, if earlier, the date on which an amount is
required to be included in the income of the Holder as a result of an Award, the
Holder shall be required to pay to the Company, in cash or in Shares (including,
but not limited to, the reservation to the Company of the requisite number of
Available Shares otherwise payable to such Holder with respect to such Award)
the amount which the Company reasonably determines to be necessary in order for
the Company to comply with applicable federal or state tax withholding


                                       16

requirements, and the collection of employment taxes, if applicable; provided,
further, that the Committee may require that such payment be made in cash.

20.      INTERPRETATION.

         (a) If any provision of the Plan is held invalid for any reason, such
holding shall not affect the remaining provisions hereof, but instead the Plan
shall be construed and enforced as if such provision had never been included in
the Plan.

         (b) THIS PLAN SHALL BE GOVERNED BY THE LAWS OF THE STATE OF TEXAS.

         (c) Headings contained in this Agreement are for convenience only and
shall in no manner be construed as part of this Plan.

         (d) Any reference to the masculine, feminine, or neuter gender shall be
a reference to such other gender as is appropriate.

         (e) The Plan is intended to constitute an "unfunded" plan for incentive
and deferred compensation. With respect to any payments not yet made to a
Holder, nothing contained herein shall give any such Holder any rights that are
greater than those of a general creditor of the Company. In its sole discretion,
the Committee may authorize the creation of trusts or other arrangements to meet
the obligations created under the Plan to deliver Common Stock or payments in
lieu of or with respect to Awards hereunder; provided, however, that, unless the
Committee otherwise determines with the consent of the affected Holder, the
existence of such trusts or other arrangements is consistent with the "unfunded"
status of the Plan.

         (f) Nothing contained in this Plan shall prevent the Board from
adopting other or additional compensation arrangements, subject to shareholder
approval if such approval is required; and such arrangements may be either
generally applicable or applicable only in specific cases.

21.      AMENDMENT AND DISCONTINUATION OF THE PLAN. The Board, or the Committee
(subject to the prior written authorization of the Board), may from time to time
amend the Plan or any Award; provided, however, that [except to the extent
provided in SECTION 9(b) AND 15 hereof] if there are Incentive Stock Options
outstanding on the date of amendment, no such amendment may, without approval by
the shareholders of the Parent, (a) increase the number of Available Shares with
respect to which Incentive Stock Options may be granted, or change the class of
Eligible Persons to which Incentive Stock Options may be granted, (b) permit the
granting of Incentive Stock Options which expire beyond the maximum 10-year
period described in SUBSECTION 9(a)(iv) or beyond the period described in
SUBSECTION 9(a)(v), or (c) extend the termination date of the Plan as set forth
in SECTION 23 with respect the granting of Incentive Stock Options; and
provided, further, that no amendment or suspension of the Plan or any Award
issued hereunder shall, except as specifically permitted in this Plan or under
the terms of such Award, substantially impair any Award previously granted to
any Holder without the consent of such Holder.

22.      SECTION 83(b) ELECTION. If as a result of receiving an Award, a
Holder receives Restricted Shares subject to a "substantial risk of forfeiture",
then such Holder may elect under Section 83(b) of the Code to include in his
gross income, for his taxable year in which the Restricted Shares are
transferred to him, the excess of the Fair Market Value (determined without
regard to any Restriction other than one which by its terms will never lapse),
of such Restricted Shares at the Date of Grant, over the amount paid for the
Restricted Shares. If the Holder makes the Section 83(b) election described
above, the Holder shall (i) make such election in a manner that is satisfactory
to the Committee, (ii) provide the Committee with a copy of such election, (iii)
agree to promptly notify the Company if any Internal Revenue Service or state
tax agent, on audit or otherwise, questions the validity or correctness of such
election or of the amount of income reportable on account of such election, and
(iv) agree to such federal and state income withholding as the Committee may
reasonably require in its sole and absolute discretion.

23.      EFFECTIVE DATE AND TERMINATION DATE. The Plan shall be effective
as of its Effective Date, and shall terminate on the tenth anniversary of such
Effective Date.
