forwarding expenses.

VOTING SECURITIES AND RECORD DATE

     The Board of Directors of the Company has fixed the close of business on 
February 26, 1999, as the Record Date (the "Record Date") for the 
determination of shareholders entitled to notice of and to vote at the Annual 
Meeting and any adjournments thereof.  Shares held by brokers and not voted 
by them ("broker non-votes") and abstentions will be counted as present at 
the Annual Meeting for purposes of determining the presence of a quorum.  
Votes at the Annual Meeting will be tabulated by an Inspector of Election 
selected by the Company.

     The issued and outstanding voting securities of the Company as of the 
Record Date consist of 5,471,782 shares of common stock, $1.00 par value per 
share ("Common Stock"), each of which is entitled to one vote.  Shares of 
Common Stock are not entitled to cumulative voting rights in the election of 
Directors. The presence in person or by proxy of the holders of a majority of 
the shares of Common Stock outstanding on the Record Date will be necessary 
to constitute a quorum at the Annual Meeting.

     Assuming the presence of a quorum of the Common Stock, the affirmative 
vote of the holders of a majority of the shares of Common Stock represented 
in person or by proxy at the meeting is required FOR the election of 
Directors, FOR approval of the Howell Corporation Omnibus Stock Awards and 
Incentive Plan, FOR approval of the Howell Corporation Nonqualified Stock 
Option Plan for Non-Employee Directors, and FOR ratification of the 
appointment of Deloitte & Touche LLP as independent auditors for the fiscal 
year ending December 31, 1999. Abstentions will have the effect of negative 
votes on all proposals to be considered at the Annual Meeting.  Broker 
non-votes will have the effect of negative votes on the proposal relating to 
the election of directors and the ratification of auditors, but will not be 
counted for purposes of the proposals relating to the adoption of the 
incentive compensation plans.

     The Company also has issued and outstanding, as of the Record Date, 
690,000 shares of $3.50 convertible preferred stock, par value $1.00 per 
share (the "Series A Preferred Stock").  Holders of the Series A Preferred 
Stock are not entitled to vote with respect to any matter referred to in this 
Proxy Statement.

ITEM 1.  ELECTION OF DIRECTORS

     The Company's Board of Directors is divided into three classes, each 
elected to serve for a term of three years.  The Board of Directors, in 
accordance with the Company's Certificate of Incorporation, has established 
that there shall be three Class I Directors, three Class II Directors and 
three Class III Directors.

     The three nominees for Class II Directors are Robert M. Ayres, Jr., 
Ronald E. Hall, and Otis A. Singletary.  It is the intention of the persons 
named in the accompanying proxy that proxies will be voted for the election 
of these three nominees unless otherwise indicated thereon.  Each of these 
persons is now a Director of the Company and is standing for reelection.  The 
Board of Directors has no reason to believe that any of the nominees will be 
unable to serve if elected to office and, to the knowledge of the Board of 
Directors, the nominees intend to serve the entire term for which election is 
sought.  Should any nominee for the office of Director named herein become 
unable or unwilling to accept nomination or election, the persons named in 
the proxy will vote for such other person as the Board of Directors may 
recommend.  The Company does not consider security holder nominations.

COMPENSATION AND NOMINATING COMMITTEE REPORT ON EXECUTIVE COMPENSATION
                                          
     The following report by the Compensation and Nominating Committee to the 
Board of Directors discusses the factors the Compensation and Nominating 
Committee considers when determining the salary and bonus of the Chief 
Executive Officer and other executive officers.

To the Board of Directors:
                                          
     As members of the Compensation and Nominating Committee, it is our duty 
to establish the compensation level of the executive officers, to award 
bonuses to the executive officers and to approve the Company's benefit plan 
arrangements.

     The base salary level of the executive officers is recommended to the 
Compensation and Nominating Committee by the Chief Executive Officer.  
Factors considered by the Chief Executive Officer are typically subjective, 
such as his perception of the individual's performance and any planned 
changes in functional responsibility, and also include such factors as prior 
year compensation levels and general inflationary considerations.  The 
profitability of the Company and the market value of its stock are not 
primary considerations in setting executive officer base compensation, 
although significant changes in these items are subjectively considered.  

     The Committee awarded no bonuses to the executive officers after 
considering the profitability of the Company and individual performance.  In 
making such determination, the Committee did not apply any specific criteria. 
The perquisites and other benefits received are reported in the Summary 
Compensation Table and are provided primarily pursuant to existing employee 
benefit programs.

     Mr. Clayton is the only member of the Compensation and Nominating 
Committee who is a current officer and employee of the Company.  No other 
member of the Compensation and Nominating Committee is a former or current 
officer, nor is an employee of the Company or any of its subsidiaries.

     The Committee does not consider security holder nominations.

STOCK OPTION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

     The following report by the Stock Option Committee to the Board of
Directors discusses the factors the Stock Option Committee considers when
administering the Company's stock option plans and recommending changes therein
and additions thereto.
                                       


                                      -5-

<PAGE>
                                       
To the Board of Directors:

     As members of the Stock Option Committee, it is our duty to administer 
the Company's stock option plans and to recommend changes therein and 
additions thereto.  The Committee believes that stock options are an 
important component of executive compensation.  Administering the Company's 
plans includes awarding stock options to executive officers and key 
employees, as well as recommending changes in existing stock option plans and 
the consideration of new plans.  The Company currently has one stock option 
plan in effect - the Howell Corporation 1997 Nonqualified Stock Option Plan 
("1997 Plan").  All of the options available for grant under the 1997 Plan 
were granted in connection with attracting the Company's current chief 
executive officer and other members of the Company's current senior 
management team to the Company in 1997.  In addition to the 538,800 options 
outstanding under the 1997 Plan, options to purchase an aggregate of 384,076 
shares are currently outstanding under the Company's 1988 Stock Option Plan 
("1988 Plan"), which expired in January 1998 but is still administered by the 
Stock Option Committee.  Consequently, at the end of January 1998 the Company 
had no shares available under its plans for additional option grants.

     The Committee believes that stock options are important in retaining 
executives and motivating them to improve performance of the Company's stock. 
The Committee also believes that the incentive effect of meaningful stock 
options is particularly important during periods of cyclical downturn in the 
oil and gas industry, since these incentives can compensate for the 
constraints on the Company's ability to compensate its executives through 
salary and cash bonuses.  The oil and gas industry, including the Company, is 
currently experiencing a cyclical downturn.  As a result, all of the 
Company's options to purchase its common stock, which were granted with 
exercise prices equal to the fair market value of the Common Stock over a 
ten-year period, now have exercise prices substantially above the current 
trading price of the Common Stock.  As a result, the Committee believes that 
the Company's currently outstanding options may have lost their incentive 
value.  The incentive value of the currently outstanding options could be 
restored by reducing their exercise prices to the level necessary to restore 
the relationship of the exercise price to the trading price of the Company's 
Common Stock existing at the date of grant.  For a number of reasons, 
including the possibility that a repricing of the currently outstanding 
options may result in changes to the Company's income in future years under 
pending changes in the method of accounting for stock options, the Committee 
determined not to recommend the repricing of any of the Company's currently 
outstanding options.

     Because of the importance of stock options in retaining executives and 
the Company's inability to grant additional options at the present time, the 
Committee has determined that the Company needs to adopt additional equity 
incentive compensation plans.  In March 1999, the Committee recommended, and 
the Board of Directors adopted, the Howell Corporation Omnibus Stock Awards 
and Incentive Plan (the "Omnibus Plan").  The Omnibus Plan will provide a new 
vehicle pursuant to which stock options and other forms of equity-based 
incentives, included stock appreciation rights, performance awards and 
restricted stock awards, could be granted to the Company's executives and key 
employees. The Omnibus Plan is described more fully elsewhere in this Proxy 
Statement.

     The number of options to be granted to each executive officer under the 
Omnibus Plan will be determined by the Stock Option Committee upon approval 
of the Omnibus Plan after considering the position and compensation level of 
the executive, the individual's contribution to the success of the Company in 
the past and the Committee's assessment of the individual's potential for 
future contribution to the success of the Company.  The Omnibus Plan contains 
a vesting schedule designed to retain executives while encouraging them to 
view their compensation, and the Company's performance, over the long term.

     In considering the Omnibus Plan, the Committee noted that grants of 
options to non-employee directors had previously been made under the 1988 
Plan.  The last such grant was in October 1997.  Of the 384,076 shares 
covered by options granted under the 1988 Plan that are currently 
outstanding, 80,000 shares are issuable pursuant to options granted to 
non-employee directors.  All of such options were granted at exercise prices 
equal to the fair market value of the shares of Common Stock on the date of 
grant, so that the exercise prices of these options are also far in excess of 
the current trading prices of the Common Stock.  The Committee believes that 
it is important to align the interests of its non-employee directors with the 
interests of its shareholders, and that stock options are an appropriate 
method to achieve this.  In view of the long tenure of the non-employee 
members of the Board of 
                                       


                                      -6-

Directors, the reduced incentive value of the current options held by them as 
a result of the cyclical downturn in the oil and gas business, the total 
amount of non-employee director compensation received by such directors at 
the Company relative to its competitors and the lack of any means to issue 
options to the directors, the Committee also proposed to the Board of 
Directors, and the Board of Directors adopted in March, 1999, the Howell 
Corporation Nonqualified Stock Option Plan for Non-Employee Directors 
("Director Plan").  The Director Plan is described more fully elsewhere in 
this Proxy Statement.

     If the Director Plan is approved by the shareholders, grants of options 
to purchase 1,000 shares will be made to non-employee directors thereunder 
automatically on the date of each annual meeting of shareholders, commencing 
in 1999.  Thereafter, each new member of the Board of Directors will be 
granted an option to purchase 10,000 shares automatically on the date of 
election and will participate in the subsequent annual grants; provided, 
however, that a newly elected director who receives an initial 10,000 share 
grant may not receive an annual grant until the second annual meeting 
following the initial 10,000 share grant.  All options will be granted at 
exercise prices equal to fair market value of the common stock on the date of 
the grant.

     In determining to recommend the adoption of both the Omnibus Plan and 
the Director Plan, the Stock Option Committee considered, among other things, 
the following matters:

     -    the number of shares of Common Stock currently outstanding;

     -    the number of shares potentially issuable on the exercise of currently
          outstanding options;

     -    the unsolicited offer by the Chairman and the President to relinquish
          all of the currently outstanding options held by them, which is
          described elsewhere in this Proxy Statement; and

     -    the effect of the provisions in the Omnibus Plan and the Director Plan
          limiting the number of options that may be granted thereunder based on
          the number of shares of stock issued on exercise of currently
          outstanding options.

After considering these and other factors, including the Committee's belief that
the Company needs to be able to grant stock options if it is to attract and
retain qualified officers and employees, the Stock Option Committee determined
to recommend the Omnibus Plan and the Director Plan to the Board of Directors
for adoption.

COMPENSATION PURSUANT TO PLANS

     The Stock Option Committee continues to administer the 1988 Plan, a 
stock option plan for its executive officers, directors and key employees 
that expired in 1988.  Under the 1988 Plan, the Stock Option Committee could 
grant both incentive and nonqualified stock options to eligible employees 
and, subject to certain limitations, members of the Board of Directors.  An 
aggregate of 750,000 shares of Common Stock had been reserved for issuance 
upon exercise of options granted under the 1988 Plan, of which 150,000 could 
be subject to options granted to Directors.  As of March 25, 1999, options 
exercisable into 375,276 shares of Common Stock remain outstanding under the 
1988 Plan.

     The Stock Option Committee also continues to administer the 1997 Plan, a 
stock option plan that expires in 2007, for its executive officers, directors 
and key employees.  Under the 1997 Plan, the Company may grant nonqualified 
options to eligible employees and members of the Board of Directors.  An 
aggregate of 538,800 shares of Common Stock has been reserved for issuance 
under the 1997 Plan, and options covering all of such shares have been 
granted.

     The following table sets forth the options granted to the individuals 
named in the Summary Compensation Table during the last fiscal year.

CERTAIN TRANSACTIONS

     In addition to serving as directors of the Company, Mr. Paul N. Howell 
and Mr. Ronald E. Hall provide advice and consultation to the Company on 
request, and are paid an annual consulting fee of $60,000 and $32,000, 
respectively, for such services.  Mr. Hall also receives a yearly auto 
allowance of $6,000.  The Board of Directors reviews these arrangements on an 
annual basis. 

     In 1990, the Company commenced paying the premiums on an insurance 
policy pursuant to a Split Dollar Life Insurance Agreement entered into 
between the Company and the trustees of certain trusts established by Paul N. 
Howell and his wife.  The life insurance policy is a joint and last survivor 
policy on the lives of Paul N. Howell and his wife.  Pursuant to the terms of 
the agreement, upon the first to occur of:  (1) the death of the last 
insured, (2) the surrender of the policy, or (3) the passing of one year 
after the policy is paid up, the Company is entitled to be paid the net cash 
value of the policy before any proceeds from the policies are paid to the 
trustees named in the agreement. During 1998, the Company paid $232,184 in 
premiums on this policy.  Because the net cash value of the policy is 
expected to be almost as much as the cumulative premiums paid over the life 
of the Agreement, the effect of the premium payments on the Company's 
earnings is not expected to be material.

     In 1990, the Company entered into a Deferred Compensation and Salary 
Continuation Agreement with Paul N. Howell, pursuant to which the Company 
contracted to pay Mr. Howell, or his wife if she survives his death, certain 
annual payments through 1999 upon his termination of employment for any 
reason. No payments were made until after Mr. Howell's retirement on May 14, 
1997.  The Company made an annual payment of $30,000 in 1998 and will make an 
annual payment of $30,000 in 1999.
 
COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

     Section 16(a) of the Securities Exchange Act of 1934 requires the 
Company's directors and officers, and persons who own more than ten percent 
of a registered class of the Company's equity securities, to file with the 
Commission and the New York Stock Exchange initial reports of ownership and 
reports of changes in ownership of Common Stock and other equity securities 
of the Company. Officers, directors and greater than ten-percent shareholders 
are required by the Commission's regulations to furnish the Company with 
copies of all Section 16(a) forms they file.

     To the Company's knowledge, based solely on review of the copies of such 
reports furnished to the Company and written representations that no other 
reports were required, all section 16(a) filing requirements applicable to 
its officers, directors and greater than ten-percent beneficial owners were 
complied with during the fiscal year ended December 31, 1998.

ITEM 2.  APPROVAL OF OMNIBUS STOCK AWARDS AND INCENTIVE PLAN

     On March 16, 1999 the Board of Directors adopted, subject to shareholder 
approval, the Howell Corporation Omnibus Stock Awards and Incentive Plan (the 
"Omnibus Plan"). A copy of the Omnibus Plan is attached to this Proxy 
Statement as Exhibit A, to which reference is made for a full statement of 
its terms. Shareholders are encouraged to read the Omnibus Plan in its 
entirety.  The following sections describe the background of the Board's 
decision to adopt the Omnibus Plan and its material terms.

BACKGROUND

     The Company currently has no plan available pursuant to which it may 
grant options to purchase Common Stock to its officers, employees and 
consultants. This is a principal reason the Company has adopted the Omnibus 
Plan.  The Company has 375,276 options outstanding under the 1988 Plan, which 
expired in January 1998.  No additional stock options may be granted under 
the 1988 Plan. The Company has 538,800 shares subject to option under its 
1997 Plan, which constituted all of the shares reserved for options under the 
1997 Plan.  No additional options may be granted under the 1997 Plan.  
Consequently, the Company has no shares available for the grant of options 
under either plan.

     Currently, 914,076 shares, representing approximately 16.7% of the 
Company's outstanding Common Stock, are subject to options granted to 
directors, officers and employees of the Company.  All of these options are 
granted at exercise prices substantially in excess of the current trading 
price of the Common Stock.  As a consequence, the Company believes that these 
options may have lost their incentive value.  For the reasons mentioned in 
the Stock Option Committee's Report on Executive Compensation, it was 
determined not to reprice these options to restore their incentive value.    
Instead, the Company determined to seek a solution that would permit the 
issuance of additional options but would not involve a repricing of existing 
options.

     The Company believes that exploration and production companies with 
market capitalizations similar to the Company have a range of approximately 
3.2% to 24.5% of their outstanding stock subject to options.  Currently, the 
Company's Chief Executive Officer and Chief Operating Officer together hold 
options under the 1997 Plan and 1988 Plan granting them the right to purchase 
a total of 530,000 of Common Stock.  The Company desired to adopt a new stock 
option plan while keeping total dilution from all stock options within the 
range of comparable companies.  In order to accomplish this goal, the 
Company's Chief Executive Officer and its Chief Operating Officer have made 
an unsolicited offer to the Company to relinquish and cancel, without 
consideration, all 530,000 options held by them upon the stockholders' 
approval of the Omnibus Plan.  By canceling the 530,000 options to purchase 
Common Stock and then reserving a like amount of shares under the Omnibus 
Plan, the Stock Option Committee believes that the Company will have a 
sufficient number of shares reserved to satisfy its need, over the 
intermediate term,  to provide equity-based incentive compensation to retain 
and attract capable and experienced personnel.

EFFECT OF FAILURE TO APPROVE THE OMNIBUS PLAN

     The Chief Executive Officer and the Chief Operating Officer have 
conditioned the cancellation of the options on the approval by the 
shareholders of the Omnibus Plan.  ACCORDINGLY, UNLESS THE SHAREHOLDERS 
APPROVE THE OMNIBUS PLAN, THE 530,000 OPTIONS HELD BY SUCH OFFICERS WILL NOT 
BE CANCELED.  In that event, the 530,000 options held by the Chief Executive 
Officer and the Chief Operating Officer will remain outstanding.  As a result:

     -    IF NEITHER THE OMNIBUS PLAN NOR THE DIRECTOR PLAN IS APPROVED BY THE
          SHAREHOLDERS, the Company would have an aggregate of 914,076 shares
          subject to option under the 1988 Plan and the 1997 Plan, including the
          530,000 options held by the Chief Executive Officer and the Chief
          Operating Officer, which would remain outstanding, and no additional
          options could be granted under either plan.  Under this scenario, a
          maximum of 914,076 shares of Common Stock could be issued pursuant to
          options granted by the Company under all of its plans, representing a
          potential dilution of approximately 16.7% to existing shareholders.

     -    IF THE OMNIBUS PLAN IS APPROVED BY THE SHAREHOLDERS, BUT THE DIRECTOR
          PLAN IS NOT, the Company would have an aggregate of 384,076 shares
          subject to option under the 1988 Plan and the 1997 


                                      -15-
<PAGE>

          Plan, and the 530,000 options held by the Chief Executive Officer 
          and the Chief Operating Officer would be canceled.  In addition, 
          the Company initially would be entitled to issue options to acquire 
          an additional 50,000 shares of Common Stock under the Omnibus Plan 
          and the 530,000 options canceled by the Chief Executive Officer and 
          the Chief Operating Officer will be credited to the shares 
          available for option under the Omnibus Plan, bringing the initial 
          number of shares issuable under that plan to 580,000 shares.  To 
          the extent that the options covering the 384,076 shares subject to 
          option under the 1988 Plan and the 1997 Plan are not exercised, the 
          number of shares subject to option under the Omnibus Plan would be 
          increased by a like amount. However, the Company would not be able 
          to grant options to its non-employee directors. Under this 
          scenario, a maximum of 964,076 shares of Common Stock could be 
          issued pursuant to options granted by the Company under all of its 
          plans, representing a potential dilution of approximately 17.6% to 
          existing shareholders. 

     -    IF THE DIRECTOR PLAN IS APPROVED BY THE SHAREHOLDERS, BUT THE OMNIBUS
          PLAN IS NOT, the Company would have an aggregate of 914,076 shares
          subject to option under the 1988 Plan and the 1997 Plan, including the
          530,000 options held by the Chief Executive Officer and the Chief
          Operating Officer, which would remain outstanding.  In addition, the
          Company would be entitled to issue options to acquire an additional
          75,000 shares of Common Stock under the Director Plan.  To the extent
          that the options covering 80,000 shares subject to options in favor of
          non-employee directors are not exercised for any reason, the number of
          shares subject to option under the Director Plan would be increased by
          a like amount.  However, the Company would be unable to grant options
          to its officers and employees; it could only grant options to its 
          non-employee directors. Under this scenario, a maximum of 989,076 
          shares of Common Stock could be issued pursuant to options granted 
          by the Company under all of its plans, representing a potential 
          dilution of approximately 18.1% to existing shareholders.

     -    IF BOTH THE DIRECTOR PLAN AND THE OMNIBUS PLAN ARE APPROVED BY THE
          SHAREHOLDERS, the Company would have an aggregate of 384,076 shares
          subject to option under the 1988 Plan and the 1997 Plan, and the
          530,000 options held by the Chief Executive Officer and the Chief
          Operating Officer would be canceled.  In addition, the Company would
          be entitled to issue options to acquire an additional 50,000 shares of
          Common Stock under the Omnibus Plan and the 530,000 options canceled
          by the Chief Executive Officer and the Chief Operating Officer will be
          credited to the shares available for option under the Omnibus Plan,
          bringing the initial number of shares issuable under that plan to
          580,000 shares.  An additional 75,000 shares of Common Stock will be
          available for options under the Directors Plan.  To the extent that
          the 304,076 options held by employees under the 1988 Plan and the 1997
          Plan are not exercised, the number of shares which may become subject
          to option under the Omnibus Plan would be increased by a like amount. 
          To the extent that the options covering 80,000 shares subject to
          options in favor of non-employee directors are not exercised for any
          reason, the number of shares subject to option under the Director
          Plan would be increased by a like amount.  Under this scenario, a
          maximum of 1,039,076 shares of Common Stock could be issued pursuant
          to options granted by the Company under all of its plans, representing
          a potential dilution of approximately 19.0% to existing shareholders.

     If both the Omnibus Plan and the Director Plan are approved by the
shareholders, the Chief Executive Officer and the Chief Operating Officer would
be eligible, as are all other officers and employees of the Company, to receive
grants of additional options thereunder in accordance with the criteria applied
by the Stock Option Committee.  See "Report of Stock Option Committee on
Executive Compensation."  Subject to approval of the Omnibus Plan by the 
Company's shareholders, the Stock Option Committee intends to recommend the 
grant of options to purchase an aggregate of 156,000 shares of Common Stock 
thereunder during 1999 to officers and employees of the Company other than 
the Chief Executive Officer and the Chief Operating Officer.  Any grants of 
options made pursuant to the Omnibus Plan prior to shareholder approval 
thereof will be made at exercise prices equal to the fair market value of the 
Common Stock on the date of the grant and will be expressly subject to the 
shareholder approval of the Omnibus Plan. However, the Stock Option Committee 
will not grant any stock options or other awards to the Chief Executive 
Officer and the Chief Operating Officer during 1999.  If the Director Plan is 
approved, an aggregate of 7,000 shares will be granted in 1999 to the current 
non-employee directors of the Company.

     The significant provisions of the Omnibus Plan are set forth in the
following sections.


                                      -16-
<PAGE>

ADMINISTRATION

     The Omnibus Plan will be administered by the Stock Option Committee of 
the Board of Directors.  The Omnibus Plan requires that the Stock Option 
Committee of the Board be (i) constituted so as to permit the plan to comply 
with Rule 16b-3 promulgated by the SEC under the Securities Exchange Act of 
1934, as amended ("Exchange Act") and (ii) composed solely of outside 
directors within the meaning of Section 162(m) of the Code.  The Stock Option 
Committee will have the power to determine which employees, officers and 
consultants will receive an award; the time or times when awards will be 
made; the type of awards to be made; the number of shares of Common Stock to 
be issued under the award or the value of the award; and the other terms and 
conditions of the awards, including the terms of any vesting provisions 
(whether based on the passage of time or the occurrence of an event, such as 
a change of control of the Company) to be included therein.

     The Stock Option Committee is authorized to interpret the Omnibus Plan 
and the agreements executed pursuant to the plan, and to prescribe such rules 
and regulations relating to the Omnibus Plan as it may consider advisable.  
The Committee may correct any defect, supply any omission or reconcile any 
inconsistency in any agreement relating to an award.  The decisions of the 
Stock Option Committee relating to the Omnibus Plan will be final and 
conclusive.

SHARES AVAILABLE

     The Omnibus Plan is intended to provide the Company with flexibility in 
providing officers, employees, and consultants an opportunity to acquire a 
proprietary interest in the Company and additional incentive and reward 
opportunities based on the growth in the Common Stock price of the Company.  
The Omnibus Plan provides for the granting of options ("non-qualified stock 
options") that do not constitute incentive stock options within the meaning 
of Section 422(b) of the Internal Revenue Code ("Code"), restricted stock 
awards and performance awards or any combination thereof.  The different 
types of awards available under the Omnibus Plan are intended to provide the 
Company with the means to keeps its compensation system competitive.

     The aggregate number of shares of Common Stock that may be subject to 
option under the Omnibus Plan has been determined pursuant to a formula 
designed to give effect to (i) the cancellation of all options currently held 
by the Chief Executive Officer and the Chief Operating Officer, and (ii) the 
exercise or cancellation, as the case may be, of the Company's other 
currently outstanding options under the 1988 Plan and the 1997 Plan.  For 
example, if both plans are approved, so that all options held by the Chief 
Executive Officer and Chief Operating Officer are canceled, and if none of 
the options to purchase 384,076 shares of Common Stock currently outstanding 
under the 1988 Plan and 1997 Plan are exercised, the aggregate number of 
shares of Common Stock that may become subject to option under the Omnibus 
Plan is 884,076 shares.  The number of shares that may be subject to option 
under the Omnibus Plan is reduced by the number of shares issued upon the 
exercise of the currently outstanding options. Accordingly, if all options 
currently outstanding under the 1988 Plan were exercised, an aggregate of 
580,000 shares could be subject to option under the Omnibus Plan.  The number 
of shares is subject to adjustment upon the occurrence of certain events, 
such as stock splits and stock dividends, as provided in Paragraph XII of the 
Plan.  Shares of Common Stock which are attributable to awards under the 
Omnibus Plan which expire, terminate or are canceled or forfeited will become 
available for issuance or use in connection with future awards.

PARTICIPATION AND ELIGIBILITY

     Under the Omnibus Plan, awards may be made only to persons who are 
employees, officers or consultants of the Company and its subsidiaries on the 
date of the award.  Non-employee directors are not eligible to receive awards 
under the Omnibus Plan.  There are currently approximately 115 employees, 
five officers and two consultants who will be eligible to participate in the 
Omnibus Plan.  Although the Company's Chief Executive Officer and the other 
executive officers named in the Summary Compensation Table are eligible to 
participate in the Omnibus Plan, the extent of their participation is in the 
discretion of the Stock Option Committee.  Accordingly, the amount of any 
benefit they may receive under the Omnibus Plan may not presently be 
determined.

TERMS AND CONDITIONS

     The Omnibus Plan became effective as of March 16, 1999, the date of its 
adoption by the Board of Directors, subject to approval of the Omnibus Plan 
by the shareholders of the Company within twelve months thereafter.  No 
awards may be granted under the Omnibus Plan after the expiration of ten 
years from the date of its adoption by the Board of Directors.  The Omnibus 
Plan remains in effect as to awards made prior to the expiration of ten years 
until such awards have been satisfied or have expired.

     STOCK OPTIONS.  The Omnibus Plan provides for the issuance of 
non-qualified stock options and not incentive stock options.  The Stock 
Option Committee will designate the persons to receive the options, the 
number of shares subject to the options and the terms and conditions, 
including provisions for vesting and acceleration of vesting, of each option 
granted under the Omnibus Plan.  Stock options may be granted in substitution 
for stock options issued by other corporations and held by individuals who 
become officers, employees or consultants of the Company as the result of a 
merger or similar transaction. The term of any option granted under the 
Omnibus Plan shall be determined by the Stock Option Committee, but may not 
exceed 10 years from the date of grant.
 
     The exercise price of options granted under the Omnibus Plan will be 
determined by the Stock Option Committee; provided, however, that the 
exercise price of an option cannot be less than the fair market value of a 
share of Common Stock on the date such option is granted (subject to certain 
adjustments provided under the Omnibus Plan).

     RESTRICTED STOCK AWARDS.  Pursuant to a restricted stock award, shares 
of Common Stock may be awarded to an eligible person without any cash payment 
to the Company, except to the extent otherwise provided by the Stock Option 
Committee or required by law; provided, however, that such shares will be 
subject to certain restrictions on the disposition thereof and certain 
obligations to forfeit such shares to the Company as may be determined in the 
discretion of the Stock Option Committee.  The restrictions on disposition 
may lapse based upon (a) the Company's attainment of specific performance 
targets established by the Stock Option Committee that are based on (i) the 
price of a share of Common Stock, (ii) the Company's earnings per share, 
(iii) the Company's revenue, (iv) the revenue of a business unit of the 
Company designated by the Stock Option Committee, (v) the return on 
stockholders' equity achieved by the Company, or (vi) the Company's pre-tax 
cash flow from operations, (b) the grantee's tenure with the Company, (c) a 
combination of factors or (d) any other factors determined by the Stock 
Option Committee in its discretion.  No more than 200,000 shares of Common 
Stock may be used for restricted stock awards under the Omnibus Plan.

     The Company will retain custody of the Common Stock issued pursuant to a 
restricted stock award until the disposition restrictions lapse.  An employee 
may not sell, transfer, pledge, exchange, hypothecate, or otherwise dispose 
of such shares until the expiration of the restriction period.  However, upon 
the issuance to the employee of Common Stock pursuant to a restricted stock 
award, except for the foregoing restrictions, such employee will have all the 
rights of a stockholder of the Company with respect to such shares, including 
the right to vote such shares and to receive all dividends and other 
distributions paid with respect to such shares.

     PERFORMANCE AWARDS.  The Omnibus Plan will permit grants of performance 
awards, which may be paid in cash, Common Stock, or a combination thereof as 
determined by the Stock Option Committee.  Performance awards granted under 
the Omnibus Plan will have a maximum value established by the Stock Option 
Committee at the time of the grant.  A grantee's receipt of such amount will 
be contingent upon satisfaction by the Company, or any subsidiary, division 
or department thereof, of performance conditions established by the Stock 
Option Committee prior to the beginning of the performance period, subject to 
later revisions as the Stock Option Committee deems appropriate to reflect 
significant unforeseen events or changes.  Future performance conditions may 
be based on (i) the price of a share of Common Stock, (ii) the Company's 
earnings per share, (iii) the Company's revenue, (iv) the revenue of a 
business unit of the Company designated by the Stock Option Committee, (v) 
the return on stockholder's equity achieved by the Company, (vi) the Company 
or business unit's pre-tax cash flow from operations, (vii) a combination of 
such factors, or (viii) any other factors or conditions determined by the 
Stock Option Committee in its discretion.  A performance award will terminate 
if the grantee's employment with the Company terminates during the applicable 
performance period except as otherwise provided by the Stock Option 
                                       


                                      -18-

<PAGE>

Committee at the time of grant.  No more than 200,000 shares of Common Stock 
may be used for performance awards under the Omnibus Plan.

     In determining the value of performance awards, the Stock Option 
Committee must take into account the employee's responsibility level, 
performance, potential, other awards under the Omnibus Plan and such other 
considerations as it deems appropriate.  Such payment may be made in a lump 
sum or in installments as prescribed by the Stock Option Committee.  Any 
payment made in Common Stock will be based upon the fair market value of the 
Common Stock on the payment date.

     The Board may provide in any option granted under the Omnibus Plan, the 
time of grant or by subsequent amendment, that the option shall become fully 
exercisable upon a "Change of Control" of the Company.  As used in the 
Omnibus Plan, the term "Change of Control" is considered to have occurred if 
(i) the Company reports the occurrence of a change of control in certain 
filings with the SEC, (ii) any person becomes the beneficial owner of 
securities of the Company representing 40% or more of the combined voting 
power of the Company's outstanding securities, or (iii) following the 
election or removal of directors, a majority of the Board consists of persons 
who were not Board members two years prior to such election or removal, 
unless the election of each person who was not a director at the beginning of 
the two-year period was approved in advance by directors representing a 
majority of the members in office at the beginning of the two-year period.  
The initial options granted to the current non-employee directors contain 
change of control provisions, and it is expected that all options granted 
under the Plan will contain such provisions.

TAX CONSEQUENCES

     Upon the exercise of a nonqualified option, the optionee will recognize 
ordinary taxable income on the amount by which the fair market value of the 
Common Stock purchased exceeds the price paid for such Common Stock under the 
option.  The Company shall be able to deduct the same amount for federal 
income tax purposes.  At the time the restrictions lapse on a restricted 
stock award, the holder of such award will recognize ordinary taxable income 
in an amount equal to the fair market value of the shares of Common Stock on 
which the restrictions lapse.  The amount of ordinary taxable income 
recognized by such holder of a restricted stock award is deductible by the 
Company.  A holder of a performance award will include in his or her ordinary 
taxable income the fair market value of the shares of Common Stock related to 
such award when the holder's rights in such award first becomes transferable 
or is no longer subject to a substantial risk of forfeiture.  The amount of 
ordinary taxable income recognized by the holder of either award is 
deductible by the Company.

AMENDMENT

     The Board may terminate or amend the Omnibus Plan at any time, but no 
such termination or amendment may impair the rights of a holder of an award 
under the Omnibus Plan without the consent of the holder.  Without 
shareholder approval, however, the Board may not amend the Omnibus Plan to 
(i) increase the maximum number of shares which may be issued on exercise or 
surrender of an award, or decrease the price at which awards may be granted, 
except in the event of a subdivision or consolidation of shares, 
recapitalization, reorganization, or change of control described in Article X 
of the Omnibus Plan, (ii) change the class of persons eligible to receive 
awards, (iii) extend either the maximum period during which awards may be 
granted or the expiration date of the Omnibus Plan, or (iv) decrease any 
authority given to the Stock Option Committee under the Omnibus Plan in 
contravention of SEC Rule 16b-3.

REQUIRED VOTE

     The affirmative vote of the stockholders holding a majority of the 
outstanding shares of Common Stock present, in person or by proxy, and 
entitled to vote at the Annual Meeting, is required to approve the adoption 
of the Omnibus Plan.  

     THE BOARD OF DIRECTORS OF THE COMPANY UNANIMOUSLY RECOMMENDS A VOTE 
"FOR" THE ADOPTION OF THE OMNIBUS PLAN.

ITEM 3.  APPROVAL OF NONQUALIFIED STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

     On March 16, 1999, the Board adopted, subject to shareholder approval, 
the Howell Corporation Nonqualified Stock Option Plan for Non-Employee 
Directors (the "Director Plan").  A copy of the Directors Plan is attached to 
this Proxy Statement as Exhibit B, to which reference is made for a full 
statement of its terms.  Shareholders are encouraged to read the Director 
Plan in its entirety. See "Item 3.  Approval of Omnibus Stock Awards and 
Incentive Plan - Background" and " - Effect of Failure to Approve Both the 
Omnibus Plan and the Director Plan" for a discussion of certain factors that 
should be considered in evaluating the Director Plan.   Set forth below is a 
summary of the significant provisions of the Director Plan.

BACKGROUND 

     The Company currently has no plan available pursuant to which it may 
grant options to purchase Common Stock to its non-employee directors.  Its 
seven current non-employee directors hold options to purchase 80,000 shares 
each, which were granted to the directors over the past ten years pursuant to 
the provisions of the 1988 Plan.  All of such options were granted at 
exercise prices equal to the fair market value of the Common Stock on the 
date of grant, and all exercise prices are substantially in excess of current 
trading prices of the Common Stock.  The 1988 Plan has expired, and no 
additional options may be granted under it.

     The Company believes that stock options serve to align the interests of 
the non-employee directors with the shareholders.  In considering the 
Director Plan, the Company believes it is important to note the long tenure 
of its current non-employee directors and the relatively modest compensation 
paid to such directors in the past in comparison to other companies.  The 
Company believes that its inability to offer equity-based incentives to its 
non-employee directors may put the Company at a disadvantage in recruiting 
such directors in the future.  The purpose of the Director Plan is to provide 
a means by which the Company, through the grant of stock options, may 
continue to attract and retain the services of experienced and knowledgeable 
non-employee directors, and to motivate such directors to exert their best 
efforts on behalf of the Company and its shareholders.  See "Stock Option 
Committee Report on Executive Compensation" for a discussion of factors 
considered by the Stock Option Committee in recommending the adoption of the 
Director Plan.

ADMINISTRATION

     The Director Plan will be administered by the entire Board of Directors. 
The Board has full power to interpret the provisions and supervise the 
administration of the Director Plan.  All actions of the Board regarding the 
Director Plan shall be taken by a majority of its members.

SHARES AVAILABLE

     An aggregate of 155,000 shares of Common Stock may be subject to option 
grants under the Director Plan, provided, that the aggregate number of shares 
of Common Stock that may be subject to outstanding options under the Director 
Plan at any one time cannot exceed the sum of 75,000 plus the total number of 
shares of Common Stock subject to outstanding options granted only to 
non-employee directors of the Company under the 1988 Plan which expire or 
lapse under the terms of the 1988 Plan or related option agreements.  There 
are currently 80,000 shares subject to options granted to non-employee 
directors under the 1988 Plan. Shares subject to option under the Director 
Plan may be authorized and unissued shares or treasury shares of the Company 
or any combination thereof as determined by the Board.  If an option granted 
under the Director Plan ceases to be exercisable in whole or in part, the 
shares representing such option shall be available under this Director Plan 
for the grant of options in the future.  The number of shares reserved for 
purposes of the Director Plan is subject to adjustment on the occurrence of 
certain events in accordance with the terms of the plan.

PARTICIPATION AND ELIGIBILITY

     Only non-employee directors of the Company are eligible to receive 
grants of options under the Director Plan.  Subject to approval of the 
Director Plan by the shareholders, each non-employee director of the Company 
serving on the Board on the date the Director Plan is approved by the 
shareholders of the Company will be granted on the date of approval an option 
to purchase 1,000 shares of Common Stock exercisable at the fair market value 
of the Common Stock on the date of the grant.  New members of the Board will 
receive initial grants of options to purchase 10,000 shares at the time of 
their election to the Board. At each Annual Meeting of Shareholders after the 
1999 Annual Meeting until the Director Plan terminates, each non-employee 
member of the Board of Directors will be granted an option to purchase 1,000 
shares of Common Stock; provided, however, that a newly elected director who 
receives an initial grant of an option to purchase 10,000 shares will not 
receive the annual grant of options to purchase 1,000 shares until the second 
annual meeting following the initial grant of options to purchase 10,000 
shares.  Such grants shall be automatic and shall continue until all options 
have been granted for all the shares under the Director Plan or until the 
Director Plan is discontinued in accordance with the terms of the Director 
Plan.  

TERMS AND CONDITIONS

     Each option under the Director Plan shall be evidenced by an agreement 
in a form determined by the Stock Option Committee.  Options granted under 
the Director Plan vest and become exercisable at the rate of 25% per year for 
each year a director serves on the Board after the option is granted.   All 
unexercised options shall expire on the tenth anniversary of their grant 
date. The purchase price for shares subject to options shall be the fair 
market value of the Common Stock on the grant date.  The purchase price shall 
be paid to the Company at the time of exercise.

     Awards under the Director Plan are not transferable except by will or by 
the laws of descent and distribution.  Options granted under the Director 
Plan shall be exercisable during the lifetime of the optionee by the optionee 
or the optionee's legal representative.  Awards under the Director Plan are 
subject to adjustment in the event of a stock dividend, stock split, 
recapitalization and combination of the Common Stock.  In the event of 
certain mergers, consolidations, plans of exchange or other reorganizations 
of the Company, outstanding options granted under the Director Plan are 
subject to adjustment to reflect the terms of such transaction.

     The Board may provide in any option granted under the Director Plan, the 
time of grant or by subsequent amendment, that the option shall become fully 
exercisable upon a "Change of Control" of the Company.  As used in the 
Director Plan, the term "Change of Control" is considered to have occurred if 
(i) the Company reports the occurrence of a change of control in certain 
filings with the SEC, (ii) any person becomes the beneficial owner of 
securities of the Company representing 40% or more of the combined voting 
power of the Company's outstanding securities, or (iii) following the 
election or removal of directors, a majority of the Board consists of persons 
who were not Board members two years prior to such election or removal, 
unless the election of each person who was not a director at the beginning of 
the two-year period was approved in advance by directors representing a 
majority of the members in office at the beginning of the two-year period.  
The initial options granted to the current non-employee directors contain 
change of control provisions, and it is expected that all options granted 
under the Plan will contain such provisions.

TAX CONSEQUENCES

     To the extent that the exercise of an option or the disposition of 
shares of Common Stock acquired by exercise of the option results in 
compensation income to the optionee for federal or state income tax purposes, 
the optionee shall pay to the Company at the time of such exercise or 
disposition such amount of money as the Company may require to meet its 
obligation under applicable tax laws or regulations.  If an optionee fails to

of shares of Stock calculated as follows: (i) 50,000, plus (ii) the total 
number of shares of Stock subject to options which are outstanding under the 
Option Plans, which were granted to employees, and which expire or lapse 
under the terms of the Option Plans or related option agreements during the

without being exercised during the term of this Plan; provided, however that 
the aggregate number of shares of Stock that may be issued under the Plan 
shall not exceed 884,076, subject to any adjustments under Paragraph X.  The

Award is to only be paid in cash or is paid in cash, any shares of Stock 
subject to such Award shall again be available for the grant of an Award. 

     (b)  STOCK OFFERED.  The stock to be offered pursuant to the grant of an 
Award may be authorized but unissued Stock or Stock previously issued and 
outstanding and reacquired by the Company.

Awards under this Plan may not be granted to any Director who is not an 
employee.  An Award may be granted on more than one occasion to the same 
person, and, subject to the limitations set forth in the Plan, such Award may 
include an Option, a Restricted Stock Award, a Performance Award, or any 
combination thereof.

Agreement in such form and containing such provisions not inconsistent with

price.  Each Option shall specify the effect of termination of employment or 
service on the exercisability of the Option.  Moreover, an Option Agreement 
may provide for a "cashless exercise" of the Option by establishing 
procedures whereby the Holder, by a properly-executed written notice, directs 
(i) an immediate market sale or margin loan respecting all or a part of the 
shares of Stock to which he is entitled upon exercise pursuant to an 
extension of credit by the brokerage firm to the Holder of the option price, 
(ii) the delivery of the shares of Stock from the Company directly to a 
brokerage firm and (iii) the delivery of the option price from the sale or 
margin loan proceeds from the brokerage firm directly to the Company.  Such 
Option Agreement may also include, without limitation, provisions relating to 
(i) vesting of Options, (ii) tax matters (including provisions (y) permitting 
the delivery of additional shares of Stock or the withholding of shares of 
Stock from those acquired upon exercise to satisfy federal or state income 
tax withholding requirements and (z) dealing with any other applicable 
employee wage withholding requirements), and (iii) any other matters not 
inconsistent with the terms and provisions of this Plan that the Committee 
shall in its sole discretion determine.  The terms and conditions of the 
respective Option Agreements need not be identical.

     (d)  OPTION PRICE AND NOTICE OF EXERCISE.  The price at which a share of 
Stock may be purchased upon exercise of an Option shall be determined by the 
Committee; provided that (i) such purchase price shall not be less than the 
Fair Market Value of Stock on the date the Option is granted and (ii) such 
purchase price shall be subject to adjustment as provided in Paragraph X.  
The Option or portion thereof may be exercised by delivery of an irrevocable 
notice of exercise to the Company.  

     (e)  STOCKHOLDER RIGHTS AND PRIVILEGES.  The Holder shall be entitled to 
all the privileges and rights of a stockholder only with respect to such 
shares of Stock as have been purchased under the Option and for which 
certificates of stock have been registered in the Holder's name.

     (f)  OPTIONS IN SUBSTITUTION FOR STOCK OPTIONS GRANTED BY OTHER 
CORPORATIONS. Options may be granted under the Plan from time to time in 
substitution for stock options held by individuals employed by corporations 
who become employees, officers or consultants as a result of a merger or 
consolidation of the employing corporation with the Company, an Affiliate, or 
any Subsidiary, or the acquisition by the Company, an Affiliate or a 
Subsidiary of the assets of the employing corporation, or the acquisition by 
the Company, an Affiliate or a Subsidiary of stock of the employing 
corporation with the result that such employing corporation becomes a 
Subsidiary.

conditions or restrictions relating to Restricted Stock Awards, including, 
but not limited to, rules pertaining to the termination of employment or the 
termination of service of a Holder prior to expiration of the Forfeiture 
Restrictions.  Such additional terms, conditions or restrictions shall be set 
forth in a Restricted Stock Agreement made in conjunction with the Award.

Agreements need not be identical.

Restricted Stock Award, except to the extent otherwise required by law.

Agreement setting forth each of the matters contemplated hereby, and, in 
addition such matters as set forth in Paragraph VIII(b) as the Committee may 
determine to be appropriate. The terms and provisions of the respective 
Restricted Stock Agreements need not be identical.

                           IX.  PERFORMANCE AWARDS

     (a)  PERFORMANCE PERIOD.  The Committee shall establish, with respect to 
and at the time of each Performance Award, a performance period over which 
the performance of the Holder shall be measured.

     (b)  PERFORMANCE AWARDS.  Each Performance Award shall have a maximum 
value established by the Committee at the time of such Award.  No more than 
200,000 shares of Stock may be used for Performance Awards.

     (c)  PERFORMANCE MEASURES.  A Performance Award shall be awarded to an 
employee contingent upon future performance of the employee, the Company, an 
Affiliate, any Subsidiary, or any division or department thereof by or in 
which he is employed during the performance period.  The Committee shall 
establish the performance measures applicable to such performance prior to 
the beginning of the performance period but subject to such later revisions 
as the Committee shall deem appropriate to reflect significant, unforeseen 
events or changes. The performance measures established by the Committee may 
be based on (i) the price of a share of Stock, (ii) the Company's earnings 
per share, (iii) the Company's revenue, (iv) the revenue of a business unit 
of the Company designated by the Committee, (v) the return on shareholders' 
equity achieved by the Company, or (vi) the Company's pre-tax cash flow from 
operations, (vii) a combination of any two or more of the factors listed in 
clauses (i) through (vi) of this sentence or (viii) any other factors or 
conditions as determined by the Committee in its sole discretion. 

     (d)  AWARDS CRITERIA.  In determining the value of Performance Awards, 
the Committee shall take into account an employee, officers or consultant's 
responsibility level, performance, potential, other Awards and such other 
considerations as it deems appropriate.

     (e)  PAYMENT.  Following the end of the performance period, the Holder 
of a Performance Award shall be entitled to receive payment of an amount, not 
exceeding the maximum value of the Performance Award, based on the 
achievement of the performance measures for such performance period, as 
determined by the Committee.  Payment of a Performance Award may be made in 
cash, Stock or a combination thereof, as determined by the Committee.  
Payment shall be made in a lump sum or in installments as prescribed by the 
Committee.  Any payment to be made in Stock shall be based on the Fair Market 
Value of the Stock on the payment date.  If a payment of cash is to be made 
on a deferred basis, the Committee shall establish whether interest shall be 
credited, the rate thereof and any other terms and conditions applicable 
thereto.

     (f)  TERMINATION OF EMPLOYMENT OR SERVICE.  A Performance Award shall 
terminate if the Holder does not remain continuously in the employ or service 
of the Employer at all times during the applicable performance period, except 
as may be determined by the Committee or as may otherwise be provided in the 
Award at the time granted.

     (g)  AGREEMENTS.  At the time any Award is made under this Paragraph IX, 
the Company and the Holder shall enter into a Performance Award Agreement 
setting forth each of the matters contemplated hereby, and, in addition such 
matters as set forth in Paragraph IX(c) as the Committee 
                                       


                                      A-8

may determine to be appropriate. The terms and provisions of the Performance 
Award Agreements need not be identical.
                                       
                    X.  RECAPITALIZATION OR REORGANIZATION

     (a)  The shares with respect to which Awards may be granted are shares 
of Stock as presently constituted, but if, and whenever, prior to the 
expiration of an Award theretofore granted, the Company shall effect a 
subdivision or consolidation of such shares of Stock or other capital 
readjustment, the number of shares of Stock with respect to which such Award 
may thereafter be exercised or satisfied, as applicable, (i) in the event of 
an increase in the number of outstanding shares shall be proportionately 
increased, and the purchase price per share shall be proportionately reduced, 
and (ii) in the event of a reduction in the number of outstanding shares 
shall be proportionately reduced, and the purchase price per share shall be 
proportionately increased.

     (b)  If the Company recapitalizes or otherwise changes its capital 
structure, thereafter upon any exercise or satisfaction, as applicable, of an 
Award theretofore granted the Holder shall be entitled to (or entitled to 
purchase, if applicable) under such Award, in lieu of the number of shares of 
Stock then covered by such Award, the number and class of shares of stock and 
securities to which the Holder would have been entitled pursuant to the terms 
of the recapitalization if, immediately prior to such recapitalization, the 
Holder had been the holder of record of the number of shares of Stock then 
covered by such Award.

     (c)  The Committee may, in its sole discretion, at the time an Award is 
granted or by amendment of the Award thereafter, provide that such Award 
shall become fully exercisable upon a Change of Control.  The Committee, in 
its discretion, may determine that upon the occurrence of a Change of 
Control, each Award other than an Option outstanding hereunder shall 
terminate within a specified reasonable number of days after notice to the 
Holder, and such Holder shall receive, with respect to each share of Stock 
subject to such Award, cash in an amount equal to the excess, if any, of the 
Change of Control Value over any exercise price or purchase price paid, if 
applicable.  If the Company is reorganized, merged or consolidated or is 
otherwise a party to a plan of exchange with another corporation pursuant to 
which reorganization, merger, consolidation or plan of exchange shareholders 
of the Company receive any shares of Stock or other securities or if the 
Company shall distribute ("Spin Off") securities of another corporation to 
its shareholders, there shall be substituted for the shares subject to the 
unexercised portions of outstanding Options granted hereunder an appropriate 
number of shares of (i) each class of stock or other securities which were 
distributed to the shareholders of the Company in respect of such shares in 
the case of a reorganization, merger, consolidation or plan of exchange, or 
(ii) in the case of a Spin Off, the securities distributed to shareholders of 
the Company together with shares of Stock, such number of shares or 
securities to be determined in accordance with the provisions of Section 425 
of the Code; provided, however, that all such Options may be canceled by the 
Company as of the effective date of (x) a reorganization, merger, 
consolidation, plan of exchange or Spin Off or (y) any dissolution or 
liquidation of the Company, by giving notice to each Holder or his personal 
representative of its intention to do so and by permitting the purchase for a 
period of at least thirty days during the sixtydays next preceding such 
effective date of all of the shares subject to such outstanding Options, 
without regard to the installment provisions set forth in the Option 
Agreements; and provided further that in the event of 
                                       


                                      A-9

<PAGE>

a Spin Off, the Company may, in lieu of substituting securities or 
accelerating and canceling Options as contemplated above, elect (i) to reduce 
the purchase price for each share of Stock subject to an outstanding Option 
by an amount equal to the fair market value of the securities distributed in 
respect of each outstanding share of Stock in the Spin Off or (ii) to reduce 
proportionately the purchase price per share and to increase proportionately 
the number of shares of Stock subject to each Option in order to reflect the 
economic benefits inuring to the shareholders of the Company as a result of 
the Spin Off.

     (d)  In the event of changes in the outstanding Stock by reason of 
recapitalization, reorganizations, mergers, consolidations, combinations, 
exchanges or other relevant changes in capitalization occurring after the 
date of the grant of any Award and not otherwise provided for by this 
Paragraph X, any outstanding Awards and any agreements evidencing such Awards 
shall be subject to adjustment by the Committee at its reasonable discretion 
as to the number and price of shares of Stock or other consideration subject 
to such Awards.  In the event of any such change in the outstanding Stock, 
the aggregate number of shares available under the Plan may be appropriately 
adjusted by the Committee, whose determination shall be reasonable and 
conclusive.

     (e)  The existence of the Plan and the Awards granted hereunder shall 
not affect in any way the right or power of the Board or the shareholders of 
the Company to make or authorize any adjustment, recapitalization, 
reorganization or other change in the Company's capital structure or its 
business, any merger or consolidation of the Company, any issue of debt or 
equity securities ahead of or affecting Stock or the rights thereof, the 
dissolution or liquidation of the Company or any sale, lease, exchange or 
other disposition of all or any part of its assets or business or any other 
corporate act or proceeding.

     (f)  Any adjustment provided for in Subparagraphs (a), (b), (c) or (d) 
above shall be subject to any required stockholder action.

     (g)  Except as hereinbefore expressly provided, the issuance by the 
Company of shares of stock of any class or securities convertible into shares 
of stock of any class, for cash, property, labor or services, upon direct 
sale, upon the exercise of rights or warrants to subscribe therefor, or upon 
conversion of shares of obligations of the Company convertible into such 
shares or other securities, and in any case whether or not for fair value, 
shall not affect, and no adjustment by reason thereof shall be made with 
respect to, the number of shares of Stock subject to Awards theretofore 
granted or the purchase price per share, if applicable.
                                       
                  XI.  AMENDMENT AND TERMINATION OF THE PLAN

     Except as set forth herein, the Board in its discretion may terminate 
the Plan at any time with respect to any shares for which Awards have not 
theretofore been granted.  Except as set forth herein, the Board shall have 
the right to alter or amend the Plan or any part thereof from time to time.  
Neither a termination of the Plan nor a change in any Award theretofore 
granted may be made which would impair the rights of the Holder without the 
consent of the Holder (unless such change is required in order to cause the 
benefits under the Plan to qualify as performance-based compensation 
                                       


                                      A-10

within the meaning of section 162(m) of the Code and applicable interpretive 
authority thereunder). The Board may not, without approval of the 
shareholders, amend the Plan:

     (a)  to increase the maximum number of shares which may be issued on 
exercise or surrender of an Award, except as provided in Paragraph X;

     (b)  to change the class of persons eligible to receive Awards;

     (c)  to extend the maximum period during which Awards may be granted 
under the Plan;

     (d)  to extend the expiration date of the Plan; 

     (e)  to decrease to any extent the price at which Awards may be granted 
under the Plan, except as provided in Paragraph X; or

     (f)  to decrease any authority granted to the Committee hereunder in 
contravention of Rule 16b-3.
                                       
                             XII.  MISCELLANEOUS

     (a)  NO RIGHT TO AN AWARD.  Neither the adoption of the Plan by the 
Company nor any action of the Board or the Committee shall be deemed to give 
an employee, officer or consultant any right to be granted an Award to 
purchase Stock, a Restricted Stock Award, or a Performance Award, or any of 
the rights hereunder except as may be evidenced by an Award or by an Option 
Agreement, a Restricted Stock Agreement, or a Performance Award Agreement on 
behalf of the Company, and then only to the extent and on the terms and 
conditions expressly set forth therein.  The Plan shall be unfunded.  The 
Company shall not be required to establish any special or separate fund or to 
make any other segregation of funds or assets to assure the payment of any 
Award.

     (b)  HOLDERS' RIGHTS UNSECURED.  The right of a Holder to receive Stock, 
cash or any other payment under this Plan shall be an unsecured claim against 
the general assets of the Company.  The Company may, but shall not be 
obligated to, acquire shares of Stock from time to time in anticipation of 
its obligations under this Plan, but a Holder shall have no right in or 
against any shares of Stock so acquired.  All Stock shall constitute the 
general assets of the Company and may be disposed of by the Company at such 
time and for such purposes as it deems appropriate.

     (c)  AGREEMENT CONTROLS.  No discretionary action by the Committee as 
set forth herein shall amend or supersede the express terms of any Agreement.

     (d)  NO EMPLOYMENT RIGHTS CONFERRED.  Nothing contained in the Plan 
shall (i) confer upon any employee any right with respect to continuation of 
employment with any Employer or (ii) interfere in any way with the right of 
any Employer to terminate an employee's employment at any time.
                                       


                                      A-11

<PAGE>

     (e)  OTHER LAWS; WITHHOLDING.  The Company shall not be obligated to 
issue any Stock pursuant to any Award granted under the Plan at any time when 
the shares covered by such Award have not been registered under the 
Securities Act of 1933 and such other state and federal laws, rules or 
regulations as the Company or the Committee deems applicable and, in the 
opinion of legal counsel for the Company, there is no exemption from the 
registration requirements of such laws, rules or regulations available for 
the issuance and sale of such shares.  Unless the Awards and Stock covered by 
this Plan have been registered under the Securities Act of 1933, or the 
Company has determined that such registration is unnecessary, each Holder 
exercising an Award under this Plan may be required by the Company to give 
representation in writing that such Holder is acquiring such shares for his 
or her own account for investment and not with a view to, or for sale in 
connection with, the distribution of any part thereof.  No fractional shares 
of Stock shall be delivered, nor shall any cash in lieu of fractional shares 
be paid.  The Company shall have the right to deduct in connection with all 
Awards any taxes required by law to be withheld and to require any payments 
required to enable it to satisfy its withholding obligations.

     (f)  NO RESTRICTION ON CORPORATE ACTION.  Nothing contained in the Plan 
shall be construed to prevent the Company, an Affiliate or any Subsidiary 
from taking any corporate action which is deemed by the Company, an Affiliate 
or any Subsidiary to be appropriate or in its best interest, whether or not 
such action would have an adverse effect on the Plan or any Award made under 
the Plan.  No Holder, beneficiary or other person shall have any claim 
against the Company, an Affiliate or any Subsidiary as a result of any such 
action.

     (g)  RESTRICTIONS ON TRANSFER.  An Award shall not be transferable 
otherwise than by will or the laws of descent and distribution and shall be 
exercisable by the Holder of such Award or the Holder's guardian or legal 
representative in accordance with the terms of the Option Agreement, 
Restricted Stock Agreement, or Performance Award Agreement.

     (h)  BENEFICIARY DESIGNATION.  Each Holder may name, from time to time, 
any beneficiary or beneficiaries (who may be named contingently or 
successively) to whom any benefit under the Plan is to be paid in case of his 
or her death before he or she receives any or all of such benefit.  Each 
designation will revoke all prior designations by the same Holder, shall be 
in a form prescribed by the Committee, and will be effective only when filed 
by the Holder in writing with the Committee during his lifetime.  In the 
absence of any such designation, benefits remaining unpaid at the Holder's 
death shall be paid to his estate.

     (i)  RULE 16b-3.  It is intended that the grant of an Award made to a 
person subject to Section 16 of the 1934 Act meet all of the requirements of 
Rule 16b-3.  If any provision of any such Award would disqualify the Plan or 
such Award under, or would otherwise not comply with, Rule 16b-3, such 
provision or Award shall be construed or deemed amended to conform to Rule 
16b-3.

     (j)  SECTION 162(m).  If the Plan is subject to Section 162(m) of the 
Code, it is intended that the Plan comply fully with and meet all the 
requirements of Section 162(m) of the Code so that Options granted hereunder 
and, if determined by the Committee, Restricted Stock Awards and Performance 
Awards, shall constitute "performance-based" compensation within the meaning 
of 
                                       


                                      A-12

<PAGE>

such section. If any provision of the Plan would disqualify the Plan or would 
not otherwise permit the Plan to comply with Section 162(m) as so intended, 
such provision shall be construed or deemed amended to conform to the 
requirements or provisions of Section 162(m); provided that no such 
construction or amendment shall have an adverse effect on the economic value 
to a Holder of any Award previously granted hereunder.

     (k)  INDEMNIFICATION. Each person who is or shall have been a member of 
the Committee or of the Board and any employee delegated authority hereunder 
shall be indemnified and held harmless by the Company against and from any 
loss, cost, liability, or expense that may be imposed upon or reasonably 
incurred by him in connection with or resulting from any claim, action, suit, 
or proceeding to which he may be a party or in which he may be involved by 
reason of any action taken or failure to act under the Plan and against and 
from any and all amounts paid by him in settlement thereof, with the 
Company's approval, or paid by him in satisfaction of any judgment in any 
such action, suit, or proceeding against him, provided he shall give the 
Company prompt written notice of any such action, suit or proceeding, and an 
opportunity, at its own expense, to handle, defend and/or settle the same 
before he undertakes to handle, defend and/or settle it on his own behalf.  
The foregoing right of indemnification shall not be exclusive of any other 
rights or indemnification to which such persons may be entitled under the 
Company's Articles of Incorporation or Bylaws, as a matter of law, or 
otherwise, or any power that the Company may have to indemnify them or hold 
them harmless. 

     (l)  GOVERNING LAW.  This Plan shall be construed in accordance with the 
laws of the State of Delaware and applicable federal law.

     IN WITNESS WHEREOF, and as conclusive evidence of the adoption of the 
foregoing by the Board, Howell Corporation has caused this document to be 
duly executed in its name and behalf by its proper officer thereunto duly 
authorized as of the date of the adoption of the Plan by the Board, being 
March 16, 1999.

                               HOWELL CORPORATION
                         NONQUALIFIED STOCK OPTION PLAN
                           FOR NON-EMPLOYEE DIRECTORS


     SECTION 1.  PURPOSE.  The purpose of this HOWELL CORPORATION 
NONQUALIFIED STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS ("PLAN") is to 
attract and retain the services of experienced and knowledgeable non-employee 
directors for Howell Corporation, a Delaware corporation (the "COMPANY"), and 
provide such non-employee directors an opportunity for ownership of common 
stock, $1.00 par value ("COMMON STOCK"), of the Company.  Options to be 
granted under this Plan will be nonqualified options which are not intended 
to qualify as Incentive Stock Options pursuant to Section 422 of the Internal 
Revenue Code of 1986, as amended ("CODE"). 

     SECTION 2.  ADMINISTRATION OF THE PLAN.  The Plan shall be administered 
by the Board of Directors of the Company ("BOARD").  Subject to the terms of 
the Plan, the Board shall have the power to interpret the provisions and 
supervise the administration of the Plan.  All decisions made by the Board 
pursuant to the provisions of the Plan shall be made by a majority of its 
members at a duly held regular or special meeting or by written consent in 
lieu of any such meeting.  A majority of the directors in office shall 
constitute a quorum and all decisions made by the Board pursuant to the 
provisions of the Plan shall be made by a majority of the directors present 
at any duly held regular or special meeting at which a quorum is present 
(unless the concurrence of a greater proportion is required by law or by the 
certificate of incorporation or bylaws of the Company) or by the written 
consent of a majority of the directors in lieu of any such meeting.  All 
expenses and liabilities incurred by the Board in the administration of this 
Plan shall be borne by the Company.  The Board may employ attorneys, 
consultants, accountants or other persons to assist the Board in the carrying 
out of its duties hereunder.

     SECTION 3.  STOCK RESERVED.  Subject to adjustment as provided in 
paragraph 5(f) and Section 6 hereof, the aggregate number of shares of Common 
Stock that may be issued under this Plan shall not exceed a number of shares 
of Common Stock calculated as follows: (i) 75,000, plus (ii) the total number 
of shares of Common Stock subject to outstanding options granted only to 
non-employee directors of the Company under the 1988 Stock Option Plan of 
Howell Corporation ("1988 Plan") and which expire or lapse under the terms of 
the 1988 Plan or related option agreements during the term of this Plan or 
which otherwise terminate or are cancelled, including but not limited to a  
relinquishment of an outstanding option for cash, without being exercised 
during the term of this Plan; provided, however that, the aggregate number of 
shares of Common Stock that may be issued under this Plan shall not exceed 
155,000, subject to any adjustments under paragraph 5(f) and Section 6.  The 
shares subject to this Plan shall consist of authorized but unissued shares 
of Common Stock or previously issued shares of Common Stock reacquired and 
held by the Company, and such number of shares shall be and is hereby 
reserved for sale for such purpose.  Any of such shares which may remain 
unsold and which are not subject to outstanding options at the termination of 
this Plan shall cease to be reserved for the purpose of this Plan, but until 
termination of this Plan or the termination of the last of the options 
granted under this Plan, whichever last occurs, the Company shall at all 
times reserve a sufficient number of shares to meet the requirements of this 
Plan.  To the extent that an option under this Plan expires, lapses, or is 
cancelled, including but not limited to a 
                                       


                                      B-1

<PAGE>

relinquishment of an outstanding option for cash, any shares of Common Stock 
subject to such option may again be made subject to an option under this Plan.

     SECTION 4.  GRANT OF OPTIONS.  Each director of the Company who is not 
otherwise an employee of the Company or any of the Company's subsidiaries (as 
defined in Section 424(f) of the Internal Revenue Code of 1986) (hereinafter 
referred to as an "ELIGIBLE DIRECTOR", which term shall include any 
transferee permitted pursuant to paragraph 5(d) below) and who is not 
currently serving as a director on the date this Plan is approved by the 
Board, shall be granted an option to acquire 10,000 shares of Common Stock 
when such Eligible Director is first elected to the Board ("INITIAL OPTION"). 
Commencing with the Annual Meeting of Shareholders approving this Plan, an 
option to acquire 1,000 shares of Common Stock ("SUBSEQUENT OPTION") shall 
automatically be granted to each Eligible Director on the date following each 
Annual Meeting of Shareholders. The term "DATE OF GRANT" means (i) in the 
case of an Initial Option granted on the date on which an Eligible Director 
not currently serving on the Board of Directors is first elected to the 
Board, the date of such initial election; and (ii) in the case of a 
Subsequent Option, the date following each Annual Meeting, provided that no 
Eligible Director shall receive a Subsequent Option at the Annual Meeting 
next following the receipt of an Initial Option.  The Initial Option and any 
Subsequent Option shall be subject to adjustment as provided for in paragraph 
5(f).

     SECTION 5.

     (a)    TERMS AND CONDITIONS.  Each option granted under this Plan shall 
be evidenced by an agreement, in a form approved by the Board, which shall be 
subject to the following express terms and conditions and to such other terms 
and conditions as the Board may deem appropriate.

     Each Initial Option and Subsequent Option shall not be exercisable for 
more than a percentage of the aggregate number of shares offered under each 
Initial Option and Subsequent Option determined by the number of full years 
occurring since the Date of Grant of each such Initial Option and Subsequent 
Option in accordance with the following schedule:

<TABLE>
<CAPTION>
     Number of Full          Percentage of    
         Years            Shares Purchasable
     --------------       ------------------
     <S>                  <C>
     Less than One                 0%
     One                          25%
     Two                          50%
     Three                        75%
     Four                        100%
</TABLE>

If an Eligible Director ceases to serve on the Board prior to the time all or 
a portion of any Initial Option or Subsequent Option becomes exercisable 
pursuant to the above schedule, the portion of such option which is not 
exercisable shall expire and be forfeited; provided however, that upon the 
                                       


                                      B-2

<PAGE>

death of an Eligible Director, all options granted the Eligible Director 
under this Plan shall be fully exercisable as set forth below and in 
accordance with paragraph 5(d).

     Each exercisable option granted under this Plan shall provide that it 
shall terminate and be of no force or effect with respect to any shares not 
previously purchased under such option by an Eligible Director upon the first 
to occur of (i) the expiration of ten years from the Date of Grant of the 
option or (ii) the expiration of one hundred eighty (180) days after the 
termination of the Eligible Director's service as a Director of the Company 
for any reason.

     (b)  EXERCISE PRICE.  The exercise price of each share of Common Stock 
subject to an Initial Option or Subsequent Option shall be the fair market 
value of a share of Common Stock on the Date of Grant of the Initial Option 
or Subsequent Option.  For all purposes under this Plan, the fair market 
value of a share of Common Stock means, as of any specified date, the closing 
price of the Common Stock as reported in The Wall Street Journal's New York 
Stock Exchange ("NYSE") - Composite Transactions listing for such day 
(corrected for obvious typographical errors), or if the shares are listed for 
trading on the NYSE but no closing price is reported in such listing for such 
day, then the last reported closing price for such shares on the NYSE, or if 
such shares are not listed or traded on the NYSE, the closing sales price on 
any national securities exchange on which the Common Stock is traded, or if 
the Common Stock is not traded on any national securities exchange, then the 
mean of the reported high and low sales prices for such shares in the 
over-the-counter market, as reported on the National Association of 
Securities Dealers Automated Quotations System, or, if such prices shall not 
be reported thereon, the mean between the closing bid and asked prices 
reported by the National Quotation Bureau Incorporated, or, in all other 
cases, the value established by the Board in good faith.

     (c)  PROCEDURE FOR EXERCISE.  Options shall be exercised by the delivery 
by the Eligible Director of written notice to the Secretary of the Company 
setting forth the number of shares of Common Stock with respect to which the 
option is being exercised.  The notice shall be accompanied by, at the 
election of the Eligible Director, (i) cash, cashier's check, bank draft, or 
postal or express money order payable to the order of the Company, (ii) 
certificates representing shares of Common Stock theretofore owned by the 
Eligible Director duly endorsed for transfer to the Company, or (iii) any 
combination of the preceding, equal in value to the full amount of the 
exercise price.  Moreover, an option agreement may provide for a "CASHLESS 
EXERCISE" of the option by establishing procedures whereby the Eligible 
Director, by a properly-executed written notice, directs (i) an immediate 
market sale or margin loan respecting all or a part of the shares of Common 
Stock to which he is entitled upon exercise pursuant to an extension of 
credit by the brokerage firm or other financial institution to the Eligible 
Director of the option price, (ii) the delivery of the shares of Common Stock 
from the Company directly to a brokerage firm or other financial institution 
and (iii) the delivery of the option price from the sale or margin loan 
proceeds from the brokerage firm or other financial institution directly to 
the Company.  Notice may also be delivered by telecopy provided that the 
exercise price of such shares is received by the Company via wire transfer on 
the same day the telecopy transmission is received by the Company.  The 
notice shall specify the address to which the certificates for such shares 
are to be mailed.  An option to purchase shares of Common Stock in accordance 
with this Plan shall be deemed to have been exercised immediately prior to 
the 
                                       


                                      B-3

<PAGE>

close of business on the date (i) written notice of such exercise and (ii) 
payment in full of the exercise price for the number of share for which 
options are being exercised, are both received by the Company and the 
Eligible Director shall be treated for all purposes as the record holder of 
such shares of Common Stock as of such date.

     As promptly as practicable after receipt of such written notice and 
payment, the Company shall deliver to the Eligible Director certificates for 
the number of shares with respect to which such option has been so exercised, 
issued in the Eligible Director's name or such other name as Eligible 
Director directs; provided, however, that such delivery shall be deemed 
effected for all purposes when a stock transfer agent of the Company shall 
have deposited such certificates in the United States mail, addressed to the 
Eligible Director at the address specified pursuant to this paragraph 5(c).

     (d)  TRANSFERABILITY.  An option granted pursuant to this Plan shall not 
be assignable or otherwise transferable by an Eligible Director otherwise 
than by an Eligible Director's will or by the laws of descent and 
distribution.  During the lifetime of an Eligible Director, an option shall 
be exercisable only by such Eligible Director or the Eligible Director's 
legal representative.  Any heir or legatee of the Eligible Director shall 
take rights granted herein and in the option agreement subject to the terms 
and conditions hereof and thereof.  No such transfer of any option to heirs 
or legatees of the Eligible Director shall be effective to bind the Company 
unless the Company shall have been furnished with written notice thereof and 
a copy of such evidence as the Board may deem necessary to establish the 
validity of the transfer and the acceptance by the transferee or transferees 
of the terms and conditions hereof.

     (e)  NO RIGHTS AS SHAREHOLDER.  No Eligible Director shall have any 
rights as a shareholder with respect to shares covered by an option until the 
option is exercised by written notice and accompanied by payment as provided 
in paragraph 5(c) above.

     (f)  CHANGES IN CAPITAL STRUCTURE.  If the outstanding shares of Common 
Stock or other securities of the Company, or both, for which the option is 
then exercisable shall at any time be changed or exchanged by declaration of 
a stock dividend, stock split, or combination of shares, then (i) the number 
and kind of shares of Common Stock or other securities which are subject to 
this Plan, (ii) the number and kind of shares of Common Stock or other 
securities which shall be subject to any Initial Option or Subsequent Option, 
and the total number of shares granted after such event, and (iii) the number 
and kind of shares of Common Stock or other securities which are subject to 
any options theretofore granted, and the exercise prices thereof, shall be 
appropriately and equitably adjusted so as to maintain the proportionate 
number of shares or other securities without changing the aggregate exercise 
price.

     SECTION 6.  CORPORATE TRANSACTIONS.     

     (a)  The existence of outstanding options granted hereunder shall not 
affect in any way the right or power of the Company or its shareholders to 
make or authorize any or all adjustments, recapitalizations, reorganizations, 
exchanges, or other changes in the Company's capital structure 
                                       


                                      B-4

<PAGE>

or its business, or any merger or consolidation of the Company, or any 
issuance of Common Stock or other securities or subscription rights thereto, 
or any issuance of bonds, debentures, preferred or prior preference stock 
ahead of or affecting the Common Stock or the rights thereof, or the 
dissolution or liquidation of the Company, or any sale or transfer of all or 
any part of its assets or business, or any other corporate act or proceeding, 
whether of a similar character or otherwise.

     (b)  If the Company is reorganized, merged or consolidated or is 
otherwise a party to a plan of exchange with another corporation pursuant to 
which reorganization, merger, consolidation or plan of exchange, shareholders 
of the Company receive any shares of Common Stock or other securities or if 
the Company shall distribute ("SPIN OFF") securities of another corporation 
to its shareholders, there shall be substituted for the shares subject to the 
unexercised portions of outstanding options granted hereunder an appropriate 
number of shares of (i) each class of stock or other securities which were 
distributed to the shareholders of the Company in respect of such shares in 
the case of a reorganization, merger, consolidation or plan of exchange, or 
(ii) in the case of a Spin Off, the securities distributed to shareholders of 
the Company together with shares of Common Stock, such number of shares or 
securities to be determined in accordance with the provisions of Section 425 
of the Code (or other applicable provisions of the Code or regulations issued 
thereunder which may from time to time govern the treatment of incentive 
stock options in such a transaction); provided, however, that all such 
options may be canceled by the Company as of the effective date of (x) a 
reorganization, merger, consolidation, plan of exchange or Spin Off or (y) 
any dissolution or liquidation of the Company, by giving notice to each 
Optionee or his personal representative of its intention to do so and by 
permitting the purchase for a period of at least thirty days during the sixty 
days next preceding such effective date of all of the shares subject to such 
outstanding options, without regard to the installment provisions set forth 
in the option agreements; and provided further that in the event of a Spin 
Off, the Company may, in lieu of substituting securities or accelerating and 
canceling options as contemplated above, elect (i) to reduce the purchase 
price for each share of Common Stock subject to an outstanding option by an 
amount equal to the fair market value, as determined in accordance with the 
provisions of Section 5(b), of the securities distributed in respect of each 
outstanding share of Common Stock in the Spin Off or (ii) to reduce 
proportionately the purchase price per share and to increase proportionately 
the number of shares of Common Stock subject to each ption in order to 
reflect the economic benefits inuring to the shareholders of the Company as a 
result of the Spin Off.

     (c)  The Board may, in its sole discretion, at the time the option is 
granted or by amendment of the option thereafter, provide that an option 
granted hereunder shall become fully exercisable upon a Change in Control of 
the Company (as defined in the next sentence).  A "CHANGE IN CONTROL" of the 
Company shall be conclusively deemed to have occurred if (and only if) any of 
the following shall have taken place: (i) a change in control is reported by 
the Company in response to Item 1 or Form 8-K (or any successor item of Form 
8-K or any similar item of any other reports required to be filed by the 
Company under the Securities Exchange Act of 1934, as amended ("EXCHANGE 
ACT")); (ii) any "PERSON" (as such term is used in Sections 13(d) and 
14(d)(2) of the Exchange Act) is or becomes the "BENEFICIAL OWNER" (as 
defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of 
securities of the Company representing forty percent or more of the combined 
voting power of the Company's then outstanding securities; or (iii) following 
the election 
                                       


                                      B-5

or removal of directors, a majority of the Board consists of individuals who 
were not members of the Board two years before such election or removal, 
unless the election of each director who was not a director at the beginning 
of such two-year period has been approved in advance by directors 
representing at least a majority of the directors then in office who were 
directors at the beginning of the two-year period.
  
     SECTION 7.  AMENDMENTS OR TERMINATION.  Except as set forth herein, the 
Board in its discretion may terminate the Plan at any time with respect to 
any shares for which options have not theretofore been granted.  Except as 
set forth herein, the Board shall have the right to alter or amend the Plan 
or any part thereof from time to time.  Neither a termination of the Plan nor 
a change in any options theretofore granted may be made which would impair 
the rights of an Eligible Director holding such option without the consent of 
the Eligible Director.  The Board may not, without approval of the 
shareholders, amend the Plan:

     (a)  to increase the maximum number of shares which may be issued on 
exercise or surrender of an option, except as provided in paragraph 5(f) and 
Section 6;

     (b)  to change the class of persons eligible to receive options;

     (c)  to extend the maximum period during which options may be granted 
under the Plan;

     (d)  to extend the expiration date of the Plan; or

     (e)  to decrease to any extent the price at which options may be granted 
under the Plan, except as provided in paragraph 5(f) and Section 6.

     SECTION 8.  COMPLIANCE WITH OTHER LAWS AND REGULATIONS.  This Plan, the 
grant and exercise of options thereunder, and the obligation of the Company 
to sell and deliver shares under such options, shall be subject to all 
applicable federal and state laws, rules and regulations and to such 
approvals by any governmental or regulatory agency as may be required.  The 
Company shall not be required to issue or deliver any certificates for shares 
of Common Stock prior to the completion of any registration or qualification 
of such shares under any federal or state law or issuance of any ruling or 
regulation of any government body which the Company shall, in its sole 
discretion, determine to be necessary or advisable.

     SECTION 9. PURCHASE FOR INVESTMENT.  Unless the options and shares of 
Common Stock covered by this Plan have been registered under the Securities 
Act of 1933, as amended, or the Company has determined that such registration 
is unnecessary, each person exercising an option under this Plan may be 
required by the Company to give a representation in writing that such person 
is acquiring such shares for his or her own account for investment and not 
with a view to, or for sale in connection with, the distribution of any part 
thereof.

     SECTION 10.  TAXES.

     (a)  The Company may make such provisions as it may deem appropriate for 
the withholding of any taxes which it determines is required in connection 
with any options granted under this Plan.

     (b)  Any Eligible Director may pay all or any portion of the taxes 
required to be withheld by the Company or paid by the Eligible Director in 
connection with the exercise of an option by electing to have the Company 
withhold shares of Common Stock, or by delivering previously owned shares of 
Common Stock, having a fair market value, determined in accordance with 
paragraph 5(b), equal to the amount required to be withheld or paid.  An 
Eligible Director must make the foregoing election on or before the date that 
the amount of tax to be withheld is determined.  All such elections are 
irrevocable and subject to disapproval by the Board.

     SECTION 11.  LIABILITY OF COMPANY FOR NON-ISSUANCE OF SHARES AND TAX 
CONSEQUENCES.  The Company shall not be liable to an Eligible Director or 
other persons as to:

     (a)  The non-issuance or sale of shares as to which the Company has been 
unable to obtain from any regulatory body having jurisdiction the authority 
deemed by the Company's counsel to be necessary to the lawful issuance and 
sale of any shares hereunder; and

     (b)  Any tax consequence expected, but not realized, by any Eligible 
Director or other person due to the exercise of any option granted hereunder.

     SECTION 12.  EFFECTIVENESS AND EXPIRATION OF PLAN. The Plan shall be 
effective on the date of its approval and adoption by the Board subject to 
approval of the shareholders of the Company.  All Initial Options and 
Subsequent Options granted to any Eligible Director prior to shareholder 
approval of the Plan shall be expressly subject to such approval.  If the 
shareholders of the Company fail to approve the Plan within twelve months of 
the date the Board approved the Plan, the Plan shall terminate and all 
options previously granted under the Plan shall become void and of no effect. 
The Plan shall expire ten years after the date the Board approves the Plan 
and thereafter no option shall be granted pursuant to the Plan; provided, 
however, that the Plan provisions shall remain in effect with respect to all 
options granted under the Plan until such options are satisfied or expire.

     SECTION 13.  NON-EXCLUSIVITY OF THIS PLAN.  The adoption by the Board 
shall not be construed as creating any limitations on the power of the Board 
to adopt such other incentive arrangements as it may deem desirable, 
including without limitation, the granting of restricted stock or stock 
options otherwise than under this Plan, and such arrangements may be either 
generally applicable or applicable only in specific cases.  

     SECTION 14.  GOVERNING LAW.  This Plan and any agreements hereunder 
shall be interpreted and construed in accordance with the laws of the State 
of Delaware and applicable federal law.
