EXHIBIT 10.14.1

                               HOWELL CORPORATION
                         DEFERRED COMPENSATION AGREEMENT

      THIS DEFERRED COMPENSATION AGREEMENT (the "Agreement"), dated as of
December 1, 2001 ("Effective Date"), is by and between Howell Corporation, a
Delaware corporation (the "Company"), and Richard K. Hebert (the "Executive").

                               WITNESSETH THAT:

      In consideration of the agreements hereinafter contained the parties
hereto agree as follows:

I.    Employment.  Until  Executive's  employment with the Company  terminates,
      ----------
      the Company  agrees to employ the Executive  and the Executive  agrees to
      be employed by the Company.

II.   Benefits. In addition to the base salary, equity based compensation and
      other benefits provided to Executive by the Company in consideration of
      his employment, Executive may earn up to $600,000 ("Maximum Benefit
      Amount") during a forty-nine (49) month period commencing on the Effective
      Date ("Measurement Period"). The "Benefit" to be paid Executive under this
      Agreement is calculated as follows:

A.    At the end of each calendar year during the  Measurement  Period  (except
           for any  calendar  year in which  occurs  or  follows  a  Change  in
           Control as defined in Section 3), the Compensation  Committee of the
           Board of Directors of the Company  ("Committee")  shall evaluate the
           Company's  performance  for such calendar year using  criteria as it
           may  determine  from  time  to  time  in its  sole  discretion.  The
           Committee  shall give the  Company a rating of either 1, 2, 3, 4, or
           5 for such  calendar year based on its  evaluation,  and such rating
           shall be given by the  Committee  in its sole  discretion.  For each
           rating made by the Committee,  the Executive shall earn a percentage
           ("Percentage")  of the  Maximum  Benefit  Amount as set forth in the
           following schedule:

                Rating             Percentage
                ------             ----------
                  1                 33-1/3%
                  2                   25%
                  3                   20%
                4 or 5                 0%

B.    In each calendar year, the Committee shall add the Percentages  earned by
           the  Executive  for the current  calendar year and each of the prior
           calendar  years during the  Measurement  Period.  If the sum of such
           Percentages  equals or exceeds 100%, the Company shall pay Executive
           the  Maximum  Benefit  Amount in one lump sum  payment no later than
           the business day coincident with or immediately  preceding the March
           15  following  the  end of  such  calendar  year.  If at the  end of
           Measurement  Period,  the  Executive  is not entitled to any Benefit
           set forth in the  preceding  sentence,  then the  Company  shall pay
           Executive  no  later  than  the  business  day  coincident  with  or
           immediately  preceding  the  March  15  following  the  end  of  the
           Measurement  Period an amount in one lump sum  payment  equal to the
           sum  of  the  Percentages   earned  during  the  Measurement  Period
           multiplied by the Maximum Benefit  Amount.  Upon any of the payments
           set forth in this  Section  2(b) being made,  this  Agreement  shall
           terminate,  and  the  Company  shall  have  no  further  obligations
           hereunder.   Notwithstanding   anything  in  this   Section  to  the
           contrary,  for any  calendar  year  during  the  Measurement  Period
           except  the  last,  if the sum of the  Percentages  earned  does not
           exceed 100%, the Company shall pay no Benefit hereunder.

C.    Except as  otherwise  provided in this  Section  2(c),  if,  prior to the
           March 15 on which a payment is to be made to  Executive as set forth
           in Section 2(b) above, the Executive's  employment  terminates,  the
           Company  shall be obligated to make such payment to the Executive or
           his  beneficiary  as set forth in Section 6. If,  prior to the March
           15 on which a  payment  is to be made to  Executive  as set forth in
           Section 2(b) above, the Executive's  employment is terminated by the
           Company  "For  Cause"  (as  defined   below)  or  if  the  Executive
           voluntarily   terminates  his  employment  with  the  Company,  this
           Agreement shall  immediately  terminate,  and the Company shall have
           no further  obligations  hereunder,  including the payment of all or
           any portion of the Maximum Benefit Amount.

           As used in this Agreement, the term "For Cause" means (i) willful
           misconduct by Executive of his duties as an employee, officer or
           director of the Company, (ii) gross neglect by Executive of his
           duties as an employee, officer or director of the Company, which
           continues for more than thirty (30) days after Executive's receipt of
           written notice from the Board to Executive specifically identifying
           the gross negligence of Executive and directing Executive to
           discontinue the same, (iii) the conviction of the Executive of a
           crime constituting a felony, or (iv) the commission by Executive of
           an act, other than an act taken in good faith within the course and
           scope of Executive's employment, which is directly detrimental to the
           Company and exposes the Company to material liability.

III.  Change in Control.
      -----------------

A.         If the Executive is not otherwise due and owed the Maximum Benefit
           Amount pursuant to Section 2(b), then upon the occurrence of a Change
           in Control (as defined below in Section 3) during the Measurement
           Period, the Company or its successor shall pay to the Executive the
           Maximum Benefit Amount as follows:

1.           Within fifteen (15) days of the occurrence of a Change in Control,
             the Company or its successor shall pay Executive an amount in one
             lump sum payment equal to the sum of the Percentages earned (as
             provided in Section 2) prior to the Change in Control multiplied by
             the Maximum Benefit Amount.

2.    If the Company or its successor  terminates  the  Executive's  employment
             for  any  reason  other  than  For  Cause  or  if  the   Executive
             voluntarily  terminates his employment  with the Company for "Good
             Reason" (as defined in Exhibit "A" attached  hereto),  the Company
             or its  successor  shall pay the  Executive  an amount in one lump
             sun payment  equal to the Maximum  Benefit  Amount less the amount
             (if any) paid under Section  3(a)(i)  above,  within  fifteen (15)
             days of the occurrence of such termination of employment.

3.           If the Executive remains employed by the Company or its successor
             until the last day of the Measurement Period, the Company or its
             successor shall pay the Executive an amount in one lump sum payment
             equal to the Maximum Benefit Amount less the amount (if any) paid
             under Section 3(a)(i) above, no later than the business day
             coincident with or immediately preceding the March 15 following the
             end of such calendar year.

4.           If, prior to the last day of the Measurement Period, the
             Executive's employment is terminated by the Company or its
             successor For Cause or the Executive voluntarily terminates his
             employment with the Company or its successor other than for Good
             Reason, this Agreement shall immediately terminate, and the Company
             or its successor shall have no further obligation hereunder,
             including the payment of all or any portion of the Maximum Benefit
             Amount.

5.           Upon any of the payments set forth in Sections 3(a)(ii) and (iii)
             above being made, this Agreement shall terminate, and the Company
             or its successor thereto shall have no further obligations
             hereunder.

B.    As used herein,  the term "Change in Control"  shall mean the  occurrence
           with respect to the Company of any of the following events:

1.    a report  on  Schedule  13D is filed  with the  Securities  and  Exchange
             Commission   (the  "SEC")   pursuant  to   Section 13(d)   of  the
             Securities  Exchange Act of 1934, as amended (the "Exchange Act"),
             disclosing  that any person,  entity or group  (within the meaning
             of  Section 13(d)  or 14(d) of the Exchange  Act),  other than the
             Company (or one of its  subsidiaries) or any employee benefit plan
             sponsored  by the  Company  (or one of its  subsidiaries),  is the
             beneficial   owner  (as  such  term  is  defined   in   Rule 13d-3
             promulgated  under the Exchange Act),  directly or indirectly,  of
             40% or more of the  outstanding  shares  of  common  stock  of the

             subsidiaries)  or  any  employee  benefit  plan  sponsored  by the

             common  stock) for cash,  securities  or any other  consideration,
             provided that after consummation of the offer, the person,  entity
             or group in  question  is the  beneficial  owner  (as such term is
             defined  in  Rule 13d-3   promulgated  under  the  Exchange  Act),
             directly  or  indirectly,  of 40% or more of the  combined  voting

4.    the stockholders of the Company shall approve:

a.    any merger, consolidation, or reorganization of the Company:

i.    in which the Company is not the continuing or surviving corporation;

                  power of the then outstanding securities of the Company; or

iv.   in which the Company will not survive as an  independent,  publicly owned
                  corporation;

b.    any sale,  lease,  exchange or other  transfer (in one  transaction  or a
                series of related  transactions)  of all or  substantially  all

             person,  entity or group (within the meaning of  Section 13(d)  or
             14(d) of the  Exchange  Act) would own  beneficially  in excess of

6.           during any period of two consecutive years, the individuals who at
             the beginning of such period constituted the Board cease for any
             reason to constitute a majority of the Board, unless the election
             or nomination for election by the Company's stockholders of each
             new director during any such two-year period was approved by the
             vote of two-thirds of the directors then still in office who were
             directors at the beginning of such two-year period.

IV.   No  Funding  Requirement.  Nothing  contained  in this  Agreement  and no
      ------------------------
      action taken pursuant to the  provisions of this  Agreement  shall create
      or  be  construed  to  create  a  trust  of  any  kind,  or  a  fiduciary
      relationship  between  the  Company  and the  Executive,  his  designated
      beneficiary  or any other person.  Any funds which may be invested  under
      the provisions of this Agreement  shall continue for all purposes to be a
      part of the general  funds of the  Company  and no person  other than the
      Company  shall by virtue of the  provisions  of this  Agreement  have any
      interest  in such funds.  To the extent that any person  acquires a right
      to receive  payments  from the Company under this  Agreement,  such right
      shall be no greater than the right of any unsecured  general  creditor of
      the Company.

V.    Non-Alienation. The right of the Executive or any other person to the
      payment of the Benefit or other benefits under this Agreement shall not be
      assigned, transferred, pledged or encumbered except by will or by the laws
      of descent and distribution.

VI.   Beneficiaries.  If the Board of Directors  of the Company  (the  "Board")
      -------------
      shall  find that any person to whom any  payment  is  payable  under this
      Agreement  is  unable  to care for his  affairs  because  of  illness  or
      accident,  or is a minor,  any payment due (unless a prior claim therefor
      shall have been made by a duly  appointed  guardian,  committee  or other
      legal  representative) may be paid to the spouse, a child, a parent, or a
      brother or sister,  or to any person deemed by the Board to have incurred
      expense for such  person  otherwise  entitled to payment,  in such manner
      and  proportions as the Board may determine.  Any such payment shall be a
      complete   discharge  of  the  liabilities  of  the  Company  under  this
      Agreement.

VII.  Miscellaneous.
      -------------

A.    Nothing  contained  herein  shall be  construed  as  conferring  upon the
           Executive  the right to  continue in the employ of the Company as an
           executive or in any other capacity.

B.         The Benefit payable under this Agreement shall not be deemed salary
           or other compensation to the Executive for the purpose of computing
           benefits to which he may be entitled under any pension plan or other
           arrangement of the Company for the benefit of its employees.

C.    The  Committee   shall  have  full  power  and  authority  to  interpret,
           construe,   and  administer   this  Agreement  and  the  Committee's
           interpretations  and  construction  thereof,  shall be  binding  and
           conclusive  on all  persons  for  all  purposes.  No  member  of the
           Committee  shall be liable to any  person  for any  action  taken or
           omitted in connection with the  interpretation and administration of
           this Agreement unless  attributable to his own willful misconduct or
           lack of good faith.

D.         Any questions as to whether and when there has been a termination of
           employment and the cause of such termination shall be determined by
           the Committee, and its determination shall be final.

E.    This  Agreement  shall be  binding  upon and inure to the  benefit of the
           Company,  its  successors  and assigns,  and the  Executive  and his
           heirs, executors, administrators, and legal representatives.

F.    This Agreement  shall be construed in accordance with and governed by the
           law of the State of Delaware.

      In WITNESS WHEREOF, the Company has caused this Agreement to be executed
by its duly authorized officers and has hereunto set his hand as of the date
first above written.

(iv)       the failure by the Company to increase Executive's Base Salary in a

           with respect to similarly positioned employees or (B) the Company's
           practices implemented subsequent to the Change in Control with

(v)   the  failure  of  the   Company  to   continue   in  effect   Executive's
           participation   in  (A) the   Company's   employee   benefit  plans,
           programs,  arrangements  and  policies,  at  a  level  substantially
           equivalent in value to and on a basis  consistent  with the relative

           in  effect  prior  to a  Change  in  Control  or  (B) the  Company's
           employee  benefit  plans,  programs,   arrangements,   and  policies

           successor to a material portion of the business or assets of the
           Company) a satisfactory assumption in writing of the Company's
           obligations under the Agreement; or

           of Executive pursuant to a request made by Executive in conformity
           with the provisions of any indemnity agreement between the Company
           and Executive or (B) to indemnify Executive pursuant to the
           provisions of any indemnity agreement between Company and Executive
           or any charter or the bylaw provisions; or

           office space, related facilities, and support personnel (including,
           but not limited to, administrative and secretarial assistance) that
           are both commensurate with the office or position and Executive's
           responsibilities to and position with the Company prior to a Change
           in Control and not materially dissimilar to the office space, related
           facilities, and support personnel provided to other key executive
           officers of the Company; or

(iv)       the Company notifies Executive of the Company's intention not to
           observe or perform one or more of the obligations of the Company
           under this Agreement.

                               WITNESSETH THAT:

      In consideration of the agreements hereinafter contained the parties
hereto agree as follows:

I.    Employment.  Until  Executive's  employment with the Company  terminates,
      ----------
      the Company  agrees to employ the Executive  and the Executive  agrees to
      be employed by the Company.

II.   Benefits. In addition to the base salary, equity based compensation and
      other benefits provided to Executive by the Company in consideration of
      his employment, Executive may earn up to $450,000 ("Maximum Benefit
      Amount") during a forty-nine (49) month period commencing on the Effective
      Date ("Measurement Period"). The "Benefit" to be paid Executive under this
      Agreement is calculated as follows:

A.    At the end of each calendar year during the  Measurement  Period  (except
           for any  calendar  year in which  occurs  or  follows  a  Change  in
           Control as defined in Section 3), the Compensation  Committee of the
           Board of Directors of the Company  ("Committee")  shall evaluate the
           Company's  performance  for such calendar year using  criteria as it
           may  determine  from  time  to  time  in its  sole  discretion.  The
           Committee  shall give the  Company a rating of either 1, 2, 3, 4, or
           5 for such  calendar year based on its  evaluation,  and such rating
           shall be given by the  Committee  in its sole  discretion.  For each
           rating made by the Committee,  the Executive shall earn a percentage
           ("Percentage")  of the  Maximum  Benefit  Amount as set forth in the
           following schedule:

                Rating             Percentage
                ------             ----------
                  1                 33-1/3%
                  2                   25%
                  3                   20%
                4 or 5                 0%

B.    In each calendar year, the Committee shall add the Percentages  earned by
           the  Executive  for the current  calendar year and each of the prior
           calendar  years during the  Measurement  Period.  If the sum of such
           Percentages  equals or exceeds 100%, the Company shall pay Executive
           the  Maximum  Benefit  Amount in one lump sum  payment no later than
           the business day coincident with or immediately  preceding the March
           15  following  the  end of  such  calendar  year.  If at the  end of
           Measurement  Period,  the  Executive  is not entitled to any Benefit
           set forth in the  preceding  sentence,  then the  Company  shall pay
           Executive  no  later  than  the  business  day  coincident  with  or
           immediately  preceding  the  March  15  following  the  end  of  the
           Measurement  Period an amount in one lump sum  payment  equal to the
           sum  of  the  Percentages   earned  during  the  Measurement  Period
           multiplied by the Maximum Benefit  Amount.  Upon any of the payments
           set forth in this  Section  2(b) being made,  this  Agreement  shall
           terminate,  and  the  Company  shall  have  no  further  obligations
           hereunder.   Notwithstanding   anything  in  this   Section  to  the
           contrary,  for any  calendar  year  during  the  Measurement  Period
           except  the  last,  if the sum of the  Percentages  earned  does not
           exceed 100%, the Company shall pay no Benefit hereunder.

C.    Except as  otherwise  provided in this  Section  2(c),  if,  prior to the
           March 15 on which a payment is to be made to  Executive as set forth
           in Section 2(b) above, the Executive's  employment  terminates,  the
           Company  shall be obligated to make such payment to the Executive or
           his  beneficiary  as set forth in Section 6. If,  prior to the March
           15 on which a  payment  is to be made to  Executive  as set forth in
           Section 2(b) above, the Executive's  employment is terminated by the
           Company  "For  Cause"  (as  defined   below)  or  if  the  Executive
           voluntarily   terminates  his  employment  with  the  Company,  this
           Agreement shall  immediately  terminate,  and the Company shall have
           no further  obligations  hereunder,  including the payment of all or
           any portion of the Maximum Benefit Amount.

           As used in this Agreement, the term "For Cause" means (i) willful
           misconduct by Executive of his duties as an employee, officer or
           director of the Company, (ii) gross neglect by Executive of his
           duties as an employee, officer or director of the Company, which
           continues for more than thirty (30) days after Executive's receipt of
           written notice from the Board to Executive specifically identifying
           the gross negligence of Executive and directing Executive to
           discontinue the same, (iii) the conviction of the Executive of a
           crime constituting a felony, or (iv) the commission by Executive of
           an act, other than an act taken in good faith within the course and
           scope of Executive's employment, which is directly detrimental to the
           Company and exposes the Company to material liability.

III.  Change in Control.
      -----------------

A.         If the Executive is not otherwise due and owed the Maximum Benefit
           Amount pursuant to Section 2(b), then upon the occurrence of a Change
           in Control (as defined below in Section 3) during the Measurement
           Period, the Company or its successor shall pay to the Executive the
           Maximum Benefit Amount as follows:

1.           Within fifteen (15) days of the occurrence of a Change in Control,
             the Company or its successor shall pay Executive an amount in one
             lump sum payment equal to the sum of the Percentages earned (as
             provided in Section 2) prior to the Change in Control multiplied by
             the Maximum Benefit Amount.

2.    If the Company or its successor  terminates  the  Executive's  employment
             for  any  reason  other  than  For  Cause  or  if  the   Executive
             voluntarily  terminates his employment  with the Company for "Good
             Reason" (as defined in Exhibit "A" attached  hereto),  the Company
             or its  successor  shall pay the  Executive  an amount in one lump
             sun payment  equal to the Maximum  Benefit  Amount less the amount
             (if any) paid under Section  3(a)(i)  above,  within  fifteen (15)
             days of the occurrence of such termination of employment.

3.           If the Executive remains employed by the Company or its successor
             until the last day of the Measurement Period, the Company or its
             successor shall pay the Executive an amount in one lump sum payment
             equal to the Maximum Benefit Amount less the amount (if any) paid
             under Section 3(a)(i) above, no later than the business day
             coincident with or immediately preceding the March 15 following the
             end of such calendar year.

4.           If, prior to the last day of the Measurement Period, the
             Executive's employment is terminated by the Company or its
             successor For Cause or the Executive voluntarily terminates his
             employment with the Company or its successor other than for Good
             Reason, this Agreement shall immediately terminate, and the Company
             or its successor shall have no further obligation hereunder,
             including the payment of all or any portion of the Maximum Benefit
             Amount.

5.           Upon any of the payments set forth in Sections 3(a)(ii) and (iii)
             above being made, this Agreement shall terminate, and the Company
             or its successor thereto shall have no further obligations
             hereunder.

B.    As used herein,  the term "Change in Control"  shall mean the  occurrence
           with respect to the Company of any of the following events:

1.    a report  on  Schedule  13D is filed  with the  Securities  and  Exchange
             Commission   (the  "SEC")   pursuant  to   Section 13(d)   of  the
             Securities  Exchange Act of 1934, as amended (the "Exchange Act"),
             disclosing  that any person,  entity or group  (within the meaning
             of  Section 13(d)  or 14(d) of the Exchange  Act),  other than the
             Company (or one of its  subsidiaries) or any employee benefit plan
             sponsored  by the  Company  (or one of its  subsidiaries),  is the
             beneficial   owner  (as  such  term  is  defined   in   Rule 13d-3
             promulgated  under the Exchange Act),  directly or indirectly,  of
             40% or more of the  outstanding  shares  of  common  stock  of the

             subsidiaries)  or  any  employee  benefit  plan  sponsored  by the

             common  stock) for cash,  securities  or any other  consideration,
             provided that after consummation of the offer, the person,  entity
             or group in  question  is the  beneficial  owner  (as such term is
             defined  in  Rule 13d-3   promulgated  under  the  Exchange  Act),
             directly  or  indirectly,  of 40% or more of the  combined  voting

4.    the stockholders of the Company shall approve:

a.    any merger, consolidation, or reorganization of the Company:

i.    in which the Company is not the continuing or surviving corporation;

                  power of the then outstanding securities of the Company; or

                  corporation;

b.    any sale,  lease,  exchange or other  transfer (in one  transaction  or a
                series of related  transactions)  of all or  substantially  all

             the beginning of such period constituted the Board cease for any
             reason to constitute a majority of the Board, unless the election
             or nomination for election by the Company's stockholders of each
             new director during any such two-year period was approved by the
             vote of two-thirds of the directors then still in office who were
             directors at the beginning of such two-year period.

IV.   No  Funding  Requirement.  Nothing  contained  in this  Agreement  and no
      ------------------------
      action taken pursuant to the  provisions of this  Agreement  shall create
      or  be  construed  to  create  a  trust  of  any  kind,  or  a  fiduciary
      relationship  between  the  Company  and the  Executive,  his  designated
      beneficiary  or any other person.  Any funds which may be invested  under
      the provisions of this Agreement  shall continue for all purposes to be a
      part of the general  funds of the  Company  and no person  other than the
      Company  shall by virtue of the  provisions  of this  Agreement  have any
      interest  in such funds.  To the extent that any person  acquires a right
      to receive  payments  from the Company under this  Agreement,  such right
      shall be no greater than the right of any unsecured  general  creditor of
      the Company.

V.    Non-Alienation. The right of the Executive or any other person to the
      payment of the Benefit or other benefits under this Agreement shall not be
      assigned, transferred, pledged or encumbered except by will or by the laws
      of descent and distribution.

VI.   Beneficiaries.  If the Board of Directors  of the Company  (the  "Board")
      -------------
      shall  find that any person to whom any  payment  is  payable  under this
      Agreement  is  unable  to care for his  affairs  because  of  illness  or
      accident,  or is a minor,  any payment due (unless a prior claim therefor
      shall have been made by a duly  appointed  guardian,  committee  or other
      legal  representative) may be paid to the spouse, a child, a parent, or a
      brother or sister,  or to any person deemed by the Board to have incurred
      expense for such  person  otherwise  entitled to payment,  in such manner
      and  proportions as the Board may determine.  Any such payment shall be a
      complete   discharge  of  the  liabilities  of  the  Company  under  this
      Agreement.

VII.  Miscellaneous.
      -------------

A.    Nothing  contained  herein  shall be  construed  as  conferring  upon the
           Executive  the right to  continue in the employ of the Company as an
           executive or in any other capacity.

B.         The Benefit payable under this Agreement shall not be deemed salary
           or other compensation to the Executive for the purpose of computing
           benefits to which he may be entitled under any pension plan or other
           arrangement of the Company for the benefit of its employees.

C.    The  Committee   shall  have  full  power  and  authority  to  interpret,
           construe,   and  administer   this  Agreement  and  the  Committee's
           interpretations  and  construction  thereof,  shall be  binding  and
           conclusive  on all  persons  for  all  purposes.  No  member  of the
           Committee  shall be liable to any  person  for any  action  taken or
           omitted in connection with the  interpretation and administration of
           this Agreement unless  attributable to his own willful misconduct or
           lack of good faith.

D.         Any questions as to whether and when there has been a termination of
           employment and the cause of such termination shall be determined by
           the Committee, and its determination shall be final.

E.    This  Agreement  shall be  binding  upon and inure to the  benefit of the
           Company,  its  successors  and assigns,  and the  Executive  and his
           heirs, executors, administrators, and legal representatives.

F.    This Agreement  shall be construed in accordance with and governed by the
           law of the State of Delaware.

      In WITNESS WHEREOF, the Company has caused this Agreement to be executed
by its duly authorized officers and has hereunto set his hand as of the date
first above written.

           in  effect  prior  to a  Change  in  Control  or  (B) the  Company's
           employee  benefit  plans,  programs,   arrangements,   and  policies

           Company) a satisfactory assumption in writing of the Company's
           obligations under the Agreement; or

           with the provisions of any indemnity agreement between the Company
           and Executive or (B) to indemnify Executive pursuant to the
           provisions of any indemnity agreement between Company and Executive
           or any charter or the bylaw provisions; or

           but not limited to, administrative and secretarial assistance) that
           are both commensurate with the office or position and Executive's
           responsibilities to and position with the Company prior to a Change
           in Control and not materially dissimilar to the office space, related
           facilities, and support personnel provided to other key executive
           officers of the Company; or

(vii)      the Company notifies Executive of the Company's intention not to

II.   Benefits. In addition to the base salary, equity based compensation and
      other benefits provided to Executive by the Company in consideration of
      his employment, Executive may earn up to $450,000 ("Maximum Benefit
      Amount") during a forty-nine (49) month period commencing on the Effective
      Date ("Measurement Period"). The "Benefit" to be paid Executive under this
      Agreement is calculated as follows:

A.    At the end of each calendar year during the  Measurement  Period  (except
           for any  calendar  year in which  occurs  or  follows  a  Change  in
           Control as defined in Section 3), the Compensation  Committee of the
           Board of Directors of the Company  ("Committee")  shall evaluate the
           Company's  performance  for such calendar year using  criteria as it
           may  determine  from  time  to  time  in its  sole  discretion.  The
           Committee  shall give the  Company a rating of either 1, 2, 3, 4, or
           5 for such  calendar year based on its  evaluation,  and such rating
           shall be given by the  Committee  in its sole  discretion.  For each
           rating made by the Committee,  the Executive shall earn a percentage
           ("Percentage")  of the  Maximum  Benefit  Amount as set forth in the
           following schedule:

                Rating             Percentage
                ------             ----------
                  1                 33-1/3%
                  2                   25%
                  3                   20%
                4 or 5                 0%

B.    In each calendar year, the Committee shall add the Percentages  earned by
           the  Executive  for the current  calendar year and each of the prior
           calendar  years during the  Measurement  Period.  If the sum of such
           Percentages  equals or exceeds 100%, the Company shall pay Executive
           the  Maximum  Benefit  Amount in one lump sum  payment no later than
           the business day coincident with or immediately  preceding the March
           15  following  the  end of  such  calendar  year.  If at the  end of
           Measurement  Period,  the  Executive  is not entitled to any Benefit
           set forth in the  preceding  sentence,  then the  Company  shall pay
           Executive  no  later  than  the  business  day  coincident  with  or
           immediately  preceding  the  March  15  following  the  end  of  the
           Measurement  Period an amount in one lump sum  payment  equal to the
           sum  of  the  Percentages   earned  during  the  Measurement  Period
           multiplied by the Maximum Benefit  Amount.  Upon any of the payments
           set forth in this  Section  2(b) being made,  this  Agreement  shall
           terminate,  and  the  Company  shall  have  no  further  obligations
           hereunder.   Notwithstanding   anything  in  this   Section  to  the
           contrary,  for any  calendar  year  during  the  Measurement  Period
           except  the  last,  if the sum of the  Percentages  earned  does not
           exceed 100%, the Company shall pay no Benefit hereunder.

C.    Except as  otherwise  provided in this  Section  2(c),  if,  prior to the
           March 15 on which a payment is to be made to  Executive as set forth
           in Section 2(b) above, the Executive's  employment  terminates,  the
           Company  shall be obligated to make such payment to the Executive or
           his  beneficiary  as set forth in Section 6. If,  prior to the March
           15 on which a  payment  is to be made to  Executive  as set forth in
           Section 2(b) above, the Executive's  employment is terminated by the
           Company  "For  Cause"  (as  defined   below)  or  if  the  Executive
           voluntarily   terminates  his  employment  with  the  Company,  this
           Agreement shall  immediately  terminate,  and the Company shall have
           no further  obligations  hereunder,  including the payment of all or
           any portion of the Maximum Benefit Amount.

           As used in this Agreement, the term "For Cause" means (i) willful
           misconduct by Executive of his duties as an employee, officer or
           director of the Company, (ii) gross neglect by Executive of his
           duties as an employee, officer or director of the Company, which
           continues for more than thirty (30) days after Executive's receipt of
           written notice from the Board to Executive specifically identifying
           the gross negligence of Executive and directing Executive to
           discontinue the same, (iii) the conviction of the Executive of a
           crime constituting a felony, or (iv) the commission by Executive of
           an act, other than an act taken in good faith within the course and
           scope of Executive's employment, which is directly detrimental to the
           Company and exposes the Company to material liability.

III.  Change in Control.
      -----------------

A.         If the Executive is not otherwise due and owed the Maximum Benefit
           Amount pursuant to Section 2(b), then upon the occurrence of a Change
           in Control (as defined below in Section 3) during the Measurement
           Period, the Company or its successor shall pay to the Executive the
           Maximum Benefit Amount as follows:

1.           Within fifteen (15) days of the occurrence of a Change in Control,
             the Company or its successor shall pay Executive an amount in one
             lump sum payment equal to the sum of the Percentages earned (as
             provided in Section 2) prior to the Change in Control multiplied by
             the Maximum Benefit Amount.

2.    If the Company or its successor  terminates  the  Executive's  employment
             for  any  reason  other  than  For  Cause  or  if  the   Executive
             voluntarily  terminates his employment  with the Company for "Good
             Reason" (as defined in Exhibit "A" attached  hereto),  the Company
             or its  successor  shall pay the  Executive  an amount in one lump
             sun payment  equal to the Maximum  Benefit  Amount less the amount
             (if any) paid under Section  3(a)(i)  above,  within  fifteen (15)
             days of the occurrence of such termination of employment.

3.           If the Executive remains employed by the Company or its successor
             until the last day of the Measurement Period, the Company or its
             successor shall pay the Executive an amount in one lump sum payment
             equal to the Maximum Benefit Amount less the amount (if any) paid
             under Section 3(a)(i) above, no later than the business day
             coincident with or immediately preceding the March 15 following the
             end of such calendar year.

4.           If, prior to the last day of the Measurement Period, the
             Executive's employment is terminated by the Company or its
             successor For Cause or the Executive voluntarily terminates his
             employment with the Company or its successor other than for Good
             Reason, this Agreement shall immediately terminate, and the Company
             or its successor shall have no further obligation hereunder,
             including the payment of all or any portion of the Maximum Benefit
             Amount.

5.           Upon any of the payments set forth in Sections 3(a)(ii) and (iii)
             above being made, this Agreement shall terminate, and the Company
             or its successor thereto shall have no further obligations
             hereunder.

B.    As used herein,  the term "Change in Control"  shall mean the  occurrence
           with respect to the Company of any of the following events:

1.    a report  on  Schedule  13D is filed  with the  Securities  and  Exchange
             Commission   (the  "SEC")   pursuant  to   Section 13(d)   of  the
             Securities  Exchange Act of 1934, as amended (the "Exchange Act"),
             disclosing  that any person,  entity or group  (within the meaning
             of  Section 13(d)  or 14(d) of the Exchange  Act),  other than the
             Company (or one of its  subsidiaries) or any employee benefit plan
             sponsored  by the  Company  (or one of its  subsidiaries),  is the
             beneficial   owner  (as  such  term  is  defined   in   Rule 13d-3
             promulgated  under the Exchange Act),  directly or indirectly,  of
             40% or more of the  outstanding  shares  of  common  stock  of the
             Company  or the  combined  voting  power of the  then  outstanding

             subsidiaries)  or  any  employee  benefit  plan  sponsored  by the
             Company (or one of its  subsidiaries),  shall purchase  securities
             pursuant  to a tender  offer or  exchange  offer  to  acquire  any
             common  stock  of the  Company  (or  securities  convertible  into
             common  stock) for cash,  securities  or any other  consideration,
             provided that after consummation of the offer, the person,  entity
             or group in  question  is the  beneficial  owner  (as such term is
             defined  in  Rule 13d-3   promulgated  under  the  Exchange  Act),
             directly  or  indirectly,  of 40% or more of the  combined  voting
             power  of the  then  outstanding  securities  of the  Company  (as
             determined  under  paragraph (d) of Rule 13d-3  promulgated  under
             the Exchange Act, in the case of rights to acquire common stock);

4.    the stockholders of the Company shall approve:

a.    any merger, consolidation, or reorganization of the Company:

i.    in which the Company is not the continuing or surviving corporation;

ii.   pursuant  to  which  shares  of  common  stock  of the  Company  would be

                  reorganization  owned  20% or  more  of the  combined  voting
                  power of the then outstanding securities of the Company; or

iv.   in which the Company will not survive as an  independent,  publicly owned
                  corporation;

b.    any sale,  lease,  exchange or other  transfer (in one  transaction  or a
                series of related  transactions)  of all or  substantially  all
                the assets of the Company; or

c.    any liquidation or dissolution of the Company;

5.    the  stockholders  of the Company shall approve a merger,  consolidation,
             reorganization,  recapitalization,  exchange  offer,  purchase  of
             assets or other  transaction  after the  consummation of which any
             person,  entity or group (within the meaning of  Section 13(d)  or
             14(d) of the  Exchange  Act) would own  beneficially  in excess of
             40% of the  outstanding  shares of common  stock of the Company or
             in  excess  of  40% of  the  combined  voting  power  of the  then

6.           during any period of two consecutive years, the individuals who at
             the beginning of such period constituted the Board cease for any
             reason to constitute a majority of the Board, unless the election
             or nomination for election by the Company's stockholders of each
             new director during any such two-year period was approved by the
             vote of two-thirds of the directors then still in office who were
             directors at the beginning of such two-year period.

IV.   No  Funding  Requirement.  Nothing  contained  in this  Agreement  and no
      ------------------------
      action taken pursuant to the  provisions of this  Agreement  shall create
      or  be  construed  to  create  a  trust  of  any  kind,  or  a  fiduciary
      relationship  between  the  Company  and the  Executive,  his  designated
      beneficiary  or any other person.  Any funds which may be invested  under
      the provisions of this Agreement  shall continue for all purposes to be a
      part of the general  funds of the  Company  and no person  other than the
      Company  shall by virtue of the  provisions  of this  Agreement  have any
      interest  in such funds.  To the extent that any person  acquires a right
      to receive  payments  from the Company under this  Agreement,  such right
      shall be no greater than the right of any unsecured  general  creditor of
      the Company.

V.    Non-Alienation. The right of the Executive or any other person to the
      payment of the Benefit or other benefits under this Agreement shall not be
      assigned, transferred, pledged or encumbered except by will or by the laws
      of descent and distribution.

VI.   Beneficiaries.  If the Board of Directors  of the Company  (the  "Board")
      -------------
      shall  find that any person to whom any  payment  is  payable  under this
      Agreement  is  unable  to care for his  affairs  because  of  illness  or
      accident,  or is a minor,  any payment due (unless a prior claim therefor
      shall have been made by a duly  appointed  guardian,  committee  or other
      legal  representative) may be paid to the spouse, a child, a parent, or a
      brother or sister,  or to any person deemed by the Board to have incurred
      expense for such  person  otherwise  entitled to payment,  in such manner
      and  proportions as the Board may determine.  Any such payment shall be a
      complete   discharge  of  the  liabilities  of  the  Company  under  this
      Agreement.

VII.  Miscellaneous.
      -------------

A.    Nothing  contained  herein  shall be  construed  as  conferring  upon the
           Executive  the right to  continue in the employ of the Company as an
           executive or in any other capacity.

B.         The Benefit payable under this Agreement shall not be deemed salary
           or other compensation to the Executive for the purpose of computing
           benefits to which he may be entitled under any pension plan or other
           arrangement of the Company for the benefit of its employees.

C.    The  Committee   shall  have  full  power  and  authority  to  interpret,
           construe,   and  administer   this  Agreement  and  the  Committee's
           interpretations  and  construction  thereof,  shall be  binding  and
           conclusive  on all  persons  for  all  purposes.  No  member  of the
           Committee  shall be liable to any  person  for any  action  taken or
           omitted in connection with the  interpretation and administration of
           this Agreement unless  attributable to his own willful misconduct or
           lack of good faith.

D.         Any questions as to whether and when there has been a termination of
           employment and the cause of such termination shall be determined by
           the Committee, and its determination shall be final.

E.    This  Agreement  shall be  binding  upon and inure to the  benefit of the
           Company,  its  successors  and assigns,  and the  Executive  and his
           heirs, executors, administrators, and legal representatives.

F.    This Agreement  shall be construed in accordance with and governed by the
           law of the State of Delaware.

      In WITNESS WHEREOF, the Company has caused this Agreement to be executed
by its duly authorized officers and has hereunto set his hand as of the date
first above written.

(iv)       the failure by the Company to increase Executive's Base Salary in a

           in  effect  prior  to a  Change  in  Control  or  (B) the  Company's
           employee  benefit  plans,  programs,   arrangements,   and  policies

(vi)       the failure of the Company to obtain from a successor (including a
           successor to a material portion of the business or assets of the
           Company) a satisfactory assumption in writing of the Company's
           obligations under the Agreement; or

(viii)     failure of the Company (A) to advance expenses to or for the benefit
           of Executive pursuant to a request made by Executive in conformity
           with the provisions of any indemnity agreement between the Company
           and Executive or (B) to indemnify Executive pursuant to the
           provisions of any indemnity agreement between Company and Executive
           or any charter or the bylaw provisions; or

           but not limited to, administrative and secretarial assistance) that
           are both commensurate with the office or position and Executive's
           responsibilities to and position with the Company prior to a Change
           in Control and not materially dissimilar to the office space, related
           facilities, and support personnel provided to other key executive
           officers of the Company; or

(x)        the Company notifies Executive of the Company's intention not to
           observe or perform one or more of the obligations of the Company
           under this Agreement.

Date. The Shares which are subject to the Restrictions shall hereinafter be
referred to as "Restricted Shares." The Shares which are no longer subject to
the Restrictions as set forth in this paragraph (a) and in paragraphs (f) or (g)
below shall hereinafter be referred to as "Transferable Shares."

           (b) Prior to the first to occur of (i) a Change of Control (as
defined in paragraph (g) below), (ii) a date which is within ten (10) days of
the Employee's death or disability (as provided in paragraph (f) below) or (iii)
the last day of the Restricted Period, the Company shall issue or transfer to
Employee (or cause to be issued or transferred to Employee), in the manner
hereinafter provided, the Shares. The issuance or transfer may be out of
authorized but unissued shares of Common Stock, or out of treasury shares of
Common Stock, or from an Affiliate (as defined in paragraph 6) of the Company.
Each certificate representing Restricted Shares shall be registered in
Employee's name and shall be either deposited with the Secretary of the Company
or its designee in an escrow account or held by the Secretary of the Company, at
the election of the Company, together with stock powers or other instruments of
transfer appropriately endorsed in blank by Employee (Employee hereby agreeing
to execute such stock powers or other instruments of transfer as requested by
the Company). Such certificate or certificates shall remain in such escrow
account or with the Secretary of the Company until the earlier to occur of (i)
the termination of the Restricted Period or (ii) the expiration of the
Restrictions as set forth in paragraphs (f) or (g) below. Certificates
representing the Restricted Shares shall bear a legend in substantially the
following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THE RESTRICTED STOCK
      AGREEMENT, DATED JANUARY 11, 2001 BETWEEN HOWELL CORPORATION ("COMPANY")
      AND THE REGISTERED HOLDER OF THIS CERTIFICATE. A COPY OF THE FORM OF SUCH
      AGREEMENT IS AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE
      COMPANY AND WILL BE FURNISHED WITHOUT CHARGE TO THE REGISTERED HOLDER OF
      SUCH CERTIFICATE UPON WRITTEN REQUEST.

The Company may place appropriate stop transfer instructions with respect to the
Restricted Shares with the transfer agent for the Common Stock. Upon Restricted
Shares becoming Transferable Shares, the Company shall deliver, in exchange for
the legended certificates, a certificate or certificates for such Shares to the
Employee free of the legend set forth above.

           (c) Subject to the terms of this Agreement, upon the Company's
issuance or delivery of certificates representing the Shares pursuant to
paragraph (b) above, the Employee shall, during the Restricted Period, have all
of the rights of a stockholder with respect to the Shares including, but not
limited to, the right to receive dividends, if any, as may be declared on such
Restricted Shares from time to time, and the right to vote (in person or by
proxy) such Restricted Shares at any meeting of shareholders of the Company.

           (d) The Restricted Shares, the right to receive certificates
representing the Restricted Shares and the right to vote the Restricted Shares
and to receive dividends thereon, may not be sold, assigned, transferred,
exchanged, pledged, hypothecated, or otherwise encumbered and no such purported
sale, assignment, transfer, exchange, pledge, hypothecation, or encumbrance,
whether made or created by voluntary act of Employee or any agent of Employee or
by operation of law, shall be recognized by, or be binding upon, or shall in any
manner affect the rights of, the Company or any agent or any custodian holding
certificates for the Restricted Shares during the Restricted Period, unless the
Restrictions have then expired pursuant to the provisions of paragraphs (f) or
(g) below. This provision shall not prohibit Employee from granting revocable
proxies in customary form to vote the Shares.

           (e) If the status of employment (hereinafter referred to as
"employment") of Employee with the Company or its Affiliates (as defined in
Section 6 herein) shall terminate, prior to the expiration of the Restricted
Period as set forth in paragraphs (a), (f) or (g) of this Section then, in that
event, the right to have the Restricted Shares delivered pursuant to paragraph
(b) above and any Restricted Shares outstanding shall, upon such termination of
employment, be forfeited by Employee to the Company, without the payment of any
consideration or further consideration by the Company, and neither Employee nor
any successors, heirs, assigns, or legal representatives of Employee shall
thereafter have any further rights or interest in the Restricted Shares or
certificates therefor, and Employee's name shall thereupon be deleted from the
list of the Company's stockholders with respect to the Restricted Shares.

           (f) If the employment of Employee with the Company or its Affiliates
shall terminate by reason of death or disability, any Restrictions on the
Restricted Shares shall be deemed to have expired as to the Restricted Shares as
of the date of any such occurrence, and the Restricted Shares shall thereafter
be Transferable Shares. For purposes of this Agreement, "disability" means the
inability of Employee to perform the essential requirements of his or her job
with or without reasonable accommodation.

           (g) Upon the occurrence of a Change of Control (as defined herein),
any Restrictions on the Restricted Shares set forth in this Agreement shall be
deemed to have expired, and the Restricted Shares shall thereafter be
Transferable Shares. A "Change of 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
of Form 8-K (or any successor item of Form 8-K or any similar item of any other
report required to be filed by the Company under the Securities Exchange Act of
1934, as amended ("1934 Act")); (ii) any "person" (as such term is used in
Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the 1934 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 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.

           (h) If the employment of Employee with the Company shall terminate
prior to the expiration of the Restricted Period, and there exists a dispute
between Employee and the Company as to the satisfaction of the conditions to the
release of the Shares from the Restrictions hereunder or the terms and
conditions of the Grant, the Shares shall remain subject to the Restrictions
until the resolution of such dispute, regardless of any intervening expiration
of the Restricted Period, except that any dividends that may be payable to the
holders of record of Common Stock as of a date during the period from
termination of Employee's employment to the resolution of such dispute shall:

                (1) to the extent to which such dividends would have been
           payable to Employee on the Shares, be held by the Company as part of
           its general funds, and shall be paid to or for the account of
           Employee only upon, and in the event of, a resolution of such dispute
           in a manner favorable to Employee, and

                (2) be canceled upon, and in the event of, a resolution of such
           dispute in a manner unfavorable to Employee.

      3. Taxes. To the extent that the receipt of the Restricted Shares,
Transferable Shares, or the lapse of any Restrictions results in income to
Employee for federal or state income tax purposes, Employee shall deliver to the
Company at the time of such receipt or lapse, as the case may be, such amount of
money or, if the Company so determines, shares of unrestricted Common Stock as
the Company may require to meet its obligation under applicable tax laws or
regulations, and if Employee fails to do so, the Company is authorized to
withhold from any cash or Common Stock remuneration then or thereafter payable
to Employee any tax required to be withheld by reasons of such resulting
compensation income. Employee agrees to notify the Company promptly of any tax
election made by Employee with respect to the Shares.

      4.   Changes in Capital Structure.  If at any time:
           ----------------------------

           (a) after the Effective Date and prior to the date on which the
Company issues or delivers to Employee certificates representing the Shares as

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock which would have
           been issued to Employee as a dividend with respect to the Shares if
           certificates representing the Shares had been issued or delivered to
           Employee on the Effective Date, and such additional shares of capital
           stock shall be issued or delivered to Employee contemporaneously with
           the issuance or delivery to Employee of the Shares, and shall be
           subject to the Restrictions to the same extent as the Shares, and (B)
           with respect to a dividend payable in cash or property other than
           shares of capital stock, an amount of cash or such other property
           equal to the amount of cash or other property which would have been
           paid or delivered to Employee if certificates representing the Shares
           had been issued or delivered to Employee on the Effective Date shall
           be paid or delivered to Employee as compensation income
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a
           different number or kind of shares of capital stock or other

           number or kind of shares of capital stock or other securities, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities into
           which the Common Stock has been split, combined, reclassified or
           changed or exchanged in such transaction, as if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities into which the Common
           Stock shall have been split, combined, reclassified or changed or
           exchanged in such transaction shall be issued or delivered to
           Employee in lieu of the Shares, and shall be subject to the
           Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities which
           Employee would have received in such transaction if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities which would have been
           issuable in respect of the Shares in such transaction if the Shares
           had been issued or delivered on the Effective Date shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares.

      (b)  after the  issuance  or delivery of  certificates  representing  the
Shares the Company shall:

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock issued to Employee
           as a dividend with respect to the Shares, and such additional shares
           of capital stock shall be issued or delivered to Employee
           contemporaneously with the issuance or delivery to Employee of the
           Shares, and shall be subject to the Restrictions to the same extent
           as the Shares, and (B) with respect to a dividend payable in cash or
           property other than shares of capital stock, the amount of cash or
           other property constituting the amount of the dividend with respect
           to the Shares shall be paid or delivered to Employee
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a
           different number or kind of shares of capital stock or other
           securities, or if the Company shall complete a recapitalization in
           which the Common Stock shall be changed or exchanged into a different
           number or kind of shares of capital stock or other securities, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been split, combined, reclassified or changed or exchanged in such
           transaction, and at such time as the Shares would otherwise be
           issuable or deliverable under this Agreement, certificates
           representing the shares of capital stock or other securities into
           which the Common Stock shall have been split, combined, reclassified
           or changed or exchanged in such transaction shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been converted in the merger or consolidation, and at such time as
           the Shares would otherwise be issuable or deliverable under this
           Agreement, certificates representing the shares of capital stock or
           other securities into which the Common Stock has been converted in
           the merger or consolidation shall be issued or delivered to Employee,
           and shall be subject to the Restrictions to the same extent as the
           Shares.

      5.   Compliance With Securities Laws.
           -------------------------------

           (a) Employee represents and warrants to the Company that Employee is
acquiring the Shares for his own account, for investment, and without a view to
any sale or distribution thereof in violation of any federal or state securities
laws. Employee understands that the grant of the Shares to Employee has not been
registered under the Securities Act of 1933, as amended, or the securities laws
of any state, and, accordingly, that in addition to the other restrictions
placed on the Shares by this Agreement, the Shares may not be offered, sold,
assigned, transferred, exchanged, pledged, hypothecated or otherwise encumbered
in absence of either (a) an effective registration statement under the
Securities Act of 1933, as amended, and applicable state securities laws or (b)
an opinion of counsel satisfactory to the Company that such registration is not
required.

           (b) Employee agrees that, if required by the Company, the
certificates representing the Shares (whether the Shares are Restricted Shares
or Transferable Shares) shall bear a legend in substantially the following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS
      AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED,
      EXCHANGED, PLEDGED, HYPOTHECATED OR OTHERWISE ENCUMBERED IN THE ABSENCE OF
      EITHER (1) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF
      1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS OR (2) AN OPINION
      OF COUNSEL SATISFACTORY TO HOWELL CORPORATION THAT SUCH REGISTRATION IS
      NOT REQUIRED.

            (c) Upon the execution of this Agreement and receipt of any
certificates for the Shares pursuant to this Agreement, Employee (or Employee's
legal representative upon Employee's death or disability) will enter into such
additional written representations, warranties and agreements as the Company may
reasonably request in order to comply with applicable securities laws or with
this Agreement.

employment of the Company as long as he remains as an employee of the Company or
its Affiliates. Any questions as to whether and when there has been a

determined by the Company, with the advice of the employing corporation (if an
Affiliate of the Company), and the Company's determination shall be final. For
purposes of this Agreement, "Affiliates" shall mean any "parent corporation" of
the Company and any "subsidiary corporation" of the Company within the meaning
of Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended.

      7. Binding Effect. The terms and conditions hereof shall, in accordance
with their terms, be binding upon, and inure to the benefit of, all successors

trustee in bankruptcy, or representative of creditors of Employee. This
Agreement shall be binding upon and inure to the benefit of any successors to
the Company.

                               HOWELL CORPORATION
                           RESTRICTED STOCK AGREEMENT

      This Restricted Stock Agreement ("Agreement"), entered into on the 11th
day of January 2001 (the "Effective Date"), which is the date on which the Grant
described below was approved by the Stock Option Committee of the Board of
Directors of HOWELL CORPORATION, is between HOWELL CORPORATION, a Delaware

      WHEREAS, the Company and Employee agree as follows:

      1. Award of Common Stock. The Company hereby grants (the "Grant") to
Employee Twenty-Five Thousand (25,000) shares (the "Shares") of common stock,
$1.00 par value, of the Company ("Common Stock") which shall be subject to the
restrictions on transferability set forth in paragraph 2(d) herein (the
"Restrictions") and to the other provisions of this Agreement. The Shares may be
increased as set forth in paragraph 4 below (such increases to be included in
the term "Shares"), and all such Shares shall be issued to the Employee in
accordance with paragraph 2(b) below.

      2.   Restricted Period.
           -----------------

           (a) For a period of four (4) years commencing on the Effective Date
(the "Restricted Period"), the Shares shall be subject to the Restrictions and
any other restrictions as set forth herein. The Restrictions shall expire as to
all of the Shares on January 11, 2005, the fourth anniversary of the Effective
Date. The Shares which are subject to the Restrictions shall hereinafter be
referred to as "Restricted Shares." The Shares which are no longer subject to
the Restrictions as set forth in this paragraph (a) and in paragraphs (f) or (g)
below shall hereinafter be referred to as "Transferable Shares."

           (b) Prior to the first to occur of (i) a Change of Control (as
defined in paragraph (g) below), (ii) a date which is within ten (10) days of
the Employee's death or disability (as provided in paragraph (f) below) or (iii)
the last day of the Restricted Period, the Company shall issue or transfer to
Employee (or cause to be issued or transferred to Employee), in the manner
hereinafter provided, the Shares. The issuance or transfer may be out of
authorized but unissued shares of Common Stock, or out of treasury shares of
Common Stock, or from an Affiliate (as defined in paragraph 6) of the Company.
Each certificate representing Restricted Shares shall be registered in
Employee's name and shall be either deposited with the Secretary of the Company
or its designee in an escrow account or held by the Secretary of the Company, at
the election of the Company, together with stock powers or other instruments of
transfer appropriately endorsed in blank by Employee (Employee hereby agreeing
to execute such stock powers or other instruments of transfer as requested by
the Company). Such certificate or certificates shall remain in such escrow
account or with the Secretary of the Company until the earlier to occur of (i)
the termination of the Restricted Period or (ii) the expiration of the
Restrictions as set forth in paragraphs (f) or (g) below. Certificates
representing the Restricted Shares shall bear a legend in substantially the
following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THE RESTRICTED STOCK
      AGREEMENT, DATED JANUARY 11, 2001 BETWEEN HOWELL CORPORATION ("COMPANY")
      AND THE REGISTERED HOLDER OF THIS CERTIFICATE. A COPY OF THE FORM OF SUCH
      AGREEMENT IS AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE
      COMPANY AND WILL BE FURNISHED WITHOUT CHARGE TO THE REGISTERED HOLDER OF
      SUCH CERTIFICATE UPON WRITTEN REQUEST.

The Company may place appropriate stop transfer instructions with respect to the
Restricted Shares with the transfer agent for the Common Stock. Upon Restricted
Shares becoming Transferable Shares, the Company shall deliver, in exchange for
the legended certificates, a certificate or certificates for such Shares to the
Employee free of the legend set forth above.

           (c) Subject to the terms of this Agreement, upon the Company's
issuance or delivery of certificates representing the Shares pursuant to
paragraph (b) above, the Employee shall, during the Restricted Period, have all
of the rights of a stockholder with respect to the Shares including, but not
limited to, the right to receive dividends, if any, as may be declared on such
Restricted Shares from time to time, and the right to vote (in person or by
proxy) such Restricted Shares at any meeting of shareholders of the Company.

           (d) The Restricted Shares, the right to receive certificates
representing the Restricted Shares and the right to vote the Restricted Shares
and to receive dividends thereon, may not be sold, assigned, transferred,
exchanged, pledged, hypothecated, or otherwise encumbered and no such purported
sale, assignment, transfer, exchange, pledge, hypothecation, or encumbrance,
whether made or created by voluntary act of Employee or any agent of Employee or
by operation of law, shall be recognized by, or be binding upon, or shall in any
manner affect the rights of, the Company or any agent or any custodian holding
certificates for the Restricted Shares during the Restricted Period, unless the
Restrictions have then expired pursuant to the provisions of paragraphs (f) or
(g) below. This provision shall not prohibit Employee from granting revocable
proxies in customary form to vote the Shares.

           (e) If the status of employment (hereinafter referred to as
"employment") of Employee with the Company or its Affiliates (as defined in
Section 6 herein) shall terminate, prior to the expiration of the Restricted
Period as set forth in paragraphs (a), (f) or (g) of this Section then, in that
event, the right to have the Restricted Shares delivered pursuant to paragraph
(b) above and any Restricted Shares outstanding shall, upon such termination of
employment, be forfeited by Employee to the Company, without the payment of any
consideration or further consideration by the Company, and neither Employee nor
any successors, heirs, assigns, or legal representatives of Employee shall
thereafter have any further rights or interest in the Restricted Shares or
certificates therefor, and Employee's name shall thereupon be deleted from the
list of the Company's stockholders with respect to the Restricted Shares.

           (f) If the employment of Employee with the Company or its Affiliates
shall terminate by reason of death or disability, any Restrictions on the
Restricted Shares shall be deemed to have expired as to the Restricted Shares as
of the date of any such occurrence, and the Restricted Shares shall thereafter
be Transferable Shares. For purposes of this Agreement, "disability" means the
inability of Employee to perform the essential requirements of his or her job
with or without reasonable accommodation.

           (g) Upon the occurrence of a Change of Control (as defined herein),
any Restrictions on the Restricted Shares set forth in this Agreement shall be
deemed to have expired, and the Restricted Shares shall thereafter be
Transferable Shares. A "Change of 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
of Form 8-K (or any successor item of Form 8-K or any similar item of any other
report required to be filed by the Company under the Securities Exchange Act of
1934, as amended ("1934 Act")); (ii) any "person" (as such term is used in
Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the 1934 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 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.

           (h) If the employment of Employee with the Company shall terminate
prior to the expiration of the Restricted Period, and there exists a dispute
between Employee and the Company as to the satisfaction of the conditions to the
release of the Shares from the Restrictions hereunder or the terms and
conditions of the Grant, the Shares shall remain subject to the Restrictions
until the resolution of such dispute, regardless of any intervening expiration
of the Restricted Period, except that any dividends that may be payable to the
holders of record of Common Stock as of a date during the period from
termination of Employee's employment to the resolution of such dispute shall:

                (1) to the extent to which such dividends would have been
           payable to Employee on the Shares, be held by the Company as part of
           its general funds, and shall be paid to or for the account of
           Employee only upon, and in the event of, a resolution of such dispute
           in a manner favorable to Employee, and

                (2) be canceled upon, and in the event of, a resolution of such
           dispute in a manner unfavorable to Employee.

      3. Taxes. To the extent that the receipt of the Restricted Shares,
Transferable Shares, or the lapse of any Restrictions results in income to
Employee for federal or state income tax purposes, Employee shall deliver to the
Company at the time of such receipt or lapse, as the case may be, such amount of
money or, if the Company so determines, shares of unrestricted Common Stock as
the Company may require to meet its obligation under applicable tax laws or
regulations, and if Employee fails to do so, the Company is authorized to
withhold from any cash or Common Stock remuneration then or thereafter payable
to Employee any tax required to be withheld by reasons of such resulting
compensation income. Employee agrees to notify the Company promptly of any tax
election made by Employee with respect to the Shares.

      4.   Changes in Capital Structure.  If at any time:
           ----------------------------

           (a) after the Effective Date and prior to the date on which the
Company issues or delivers to Employee certificates representing the Shares as

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock which would have
           been issued to Employee as a dividend with respect to the Shares if
           certificates representing the Shares had been issued or delivered to
           Employee on the Effective Date, and such additional shares of capital
           stock shall be issued or delivered to Employee contemporaneously with
           the issuance or delivery to Employee of the Shares, and shall be
           subject to the Restrictions to the same extent as the Shares, and (B)
           with respect to a dividend payable in cash or property other than
           shares of capital stock, an amount of cash or such other property
           equal to the amount of cash or other property which would have been
           paid or delivered to Employee if certificates representing the Shares
           had been issued or delivered to Employee on the Effective Date shall
           be paid or delivered to Employee as compensation income

           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a

           number or kind of shares of capital stock or other securities, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities into
           which the Common Stock has been split, combined, reclassified or
           changed or exchanged in such transaction, as if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities into which the Common
           Stock shall have been split, combined, reclassified or changed or
           exchanged in such transaction shall be issued or delivered to
           Employee in lieu of the Shares, and shall be subject to the
           Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities which
           Employee would have received in such transaction if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities which would have been
           issuable in respect of the Shares in such transaction if the Shares
           had been issued or delivered on the Effective Date shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares.

      (b)  after the  issuance  or delivery of  certificates  representing  the
Shares the Company shall:

           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock issued to Employee
           as a dividend with respect to the Shares, and such additional shares
           of capital stock shall be issued or delivered to Employee
           contemporaneously with the issuance or delivery to Employee of the
           Shares, and shall be subject to the Restrictions to the same extent
           as the Shares, and (B) with respect to a dividend payable in cash or
           property other than shares of capital stock, the amount of cash or
           other property constituting the amount of the dividend with respect
           to the Shares shall be paid or delivered to Employee
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a
           different number or kind of shares of capital stock or other
           securities, or if the Company shall complete a recapitalization in
           which the Common Stock shall be changed or exchanged into a different
           number or kind of shares of capital stock or other securities, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been split, combined, reclassified or changed or exchanged in such
           transaction, and at such time as the Shares would otherwise be
           issuable or deliverable under this Agreement, certificates
           representing the shares of capital stock or other securities into
           which the Common Stock shall have been split, combined, reclassified
           or changed or exchanged in such transaction shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been converted in the merger or consolidation, and at such time as
           the Shares would otherwise be issuable or deliverable under this
           Agreement, certificates representing the shares of capital stock or

           Shares.

      5.   Compliance With Securities Laws.
           -------------------------------

           (a) Employee represents and warrants to the Company that Employee is
acquiring the Shares for his own account, for investment, and without a view to
any sale or distribution thereof in violation of any federal or state securities
laws. Employee understands that the grant of the Shares to Employee has not been
registered under the Securities Act of 1933, as amended, or the securities laws
of any state, and, accordingly, that in addition to the other restrictions
placed on the Shares by this Agreement, the Shares may not be offered, sold,
assigned, transferred, exchanged, pledged, hypothecated or otherwise encumbered
in absence of either (a) an effective registration statement under the
Securities Act of 1933, as amended, and applicable state securities laws or (b)
an opinion of counsel satisfactory to the Company that such registration is not
required.

           (b) Employee agrees that, if required by the Company, the
certificates representing the Shares (whether the Shares are Restricted Shares
or Transferable Shares) shall bear a legend in substantially the following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS
      AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED,
      EXCHANGED, PLEDGED, HYPOTHECATED OR OTHERWISE ENCUMBERED IN THE ABSENCE OF
      EITHER (1) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF
      1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS OR (2) AN OPINION
      OF COUNSEL SATISFACTORY TO HOWELL CORPORATION THAT SUCH REGISTRATION IS
      NOT REQUIRED.

            (c) Upon the execution of this Agreement and receipt of any
certificates for the Shares pursuant to this Agreement, Employee (or Employee's
legal representative upon Employee's death or disability) will enter into such
additional written representations, warranties and agreements as the Company may
reasonably request in order to comply with applicable securities laws or with
this Agreement.

determined by the Company, with the advice of the employing corporation (if an
Affiliate of the Company), and the Company's determination shall be final. For
purposes of this Agreement, "Affiliates" shall mean any "parent corporation" of
the Company and any "subsidiary corporation" of the Company within the meaning

trustee in bankruptcy, or representative of creditors of Employee. This
Agreement shall be binding upon and inure to the benefit of any successors to
the Company.

                               HOWELL CORPORATION
                           RESTRICTED STOCK AGREEMENT

      This Restricted Stock Agreement ("Agreement"), entered into on the 11th
day of January 2001 (the "Effective Date"), which is the date on which the Grant
described below was approved by the Stock Option Committee of the Board of
Directors of HOWELL CORPORATION, is between HOWELL CORPORATION, a Delaware
corporation (the "Company"), and John E. Brewster, Jr. (the "Employee").

      WHEREAS, the Company and Employee agree as follows:

      1. Award of Common Stock. The Company hereby grants (the "Grant") to
Employee Three Thousand (3,000) shares (the "Shares") of common stock, $1.00 par
value, of the Company ("Common Stock") which shall be subject to the
restrictions on transferability set forth in paragraph 2(d) herein (the
"Restrictions") and to the other provisions of this Agreement. The Shares may be
increased as set forth in paragraph 4 below (such increases to be included in
the term "Shares"), and all such Shares shall be issued to the Employee in
accordance with paragraph 2(b) below.

      2.   Restricted Period.
           -----------------

           (a) For a period of four (4) years commencing on the Effective Date
(the "Restricted Period"), the Shares shall be subject to the Restrictions and
any other restrictions as set forth herein. The Restrictions shall expire as to
all of the Shares on January 11, 2005, the fourth anniversary of the Effective
Date. The Shares which are subject to the Restrictions shall hereinafter be
referred to as "Restricted Shares." The Shares which are no longer subject to
the Restrictions as set forth in this paragraph (a) and in paragraphs (f) or (g)
below shall hereinafter be referred to as "Transferable Shares."

           (b) Prior to the first to occur of (i) a Change of Control (as
defined in paragraph (g) below), (ii) a date which is within ten (10) days of
the Employee's death or disability (as provided in paragraph (f) below) or (iii)
the last day of the Restricted Period, the Company shall issue or transfer to
Employee (or cause to be issued or transferred to Employee), in the manner
hereinafter provided, the Shares. The issuance or transfer may be out of
authorized but unissued shares of Common Stock, or out of treasury shares of
Common Stock, or from an Affiliate (as defined in paragraph 6) of the Company.
Each certificate representing Restricted Shares shall be registered in
Employee's name and shall be either deposited with the Secretary of the Company
or its designee in an escrow account or held by the Secretary of the Company, at
the election of the Company, together with stock powers or other instruments of
transfer appropriately endorsed in blank by Employee (Employee hereby agreeing
to execute such stock powers or other instruments of transfer as requested by
the Company). Such certificate or certificates shall remain in such escrow
account or with the Secretary of the Company until the earlier to occur of (i)
the termination of the Restricted Period or (ii) the expiration of the
Restrictions as set forth in paragraphs (f) or (g) below. Certificates
representing the Restricted Shares shall bear a legend in substantially the
following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THE RESTRICTED STOCK
      AGREEMENT, DATED JANUARY 11, 2001 BETWEEN HOWELL CORPORATION ("COMPANY")
      AND THE REGISTERED HOLDER OF THIS CERTIFICATE. A COPY OF THE FORM OF SUCH
      AGREEMENT IS AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE
      COMPANY AND WILL BE FURNISHED WITHOUT CHARGE TO THE REGISTERED HOLDER OF
      SUCH CERTIFICATE UPON WRITTEN REQUEST.

The Company may place appropriate stop transfer instructions with respect to the
Restricted Shares with the transfer agent for the Common Stock. Upon Restricted
Shares becoming Transferable Shares, the Company shall deliver, in exchange for
the legended certificates, a certificate or certificates for such Shares to the
Employee free of the legend set forth above.

           (c) Subject to the terms of this Agreement, upon the Company's
issuance or delivery of certificates representing the Shares pursuant to
paragraph (b) above, the Employee shall, during the Restricted Period, have all
of the rights of a stockholder with respect to the Shares including, but not
limited to, the right to receive dividends, if any, as may be declared on such
Restricted Shares from time to time, and the right to vote (in person or by
proxy) such Restricted Shares at any meeting of shareholders of the Company.

           (d) The Restricted Shares, the right to receive certificates
representing the Restricted Shares and the right to vote the Restricted Shares
and to receive dividends thereon, may not be sold, assigned, transferred,
exchanged, pledged, hypothecated, or otherwise encumbered and no such purported
sale, assignment, transfer, exchange, pledge, hypothecation, or encumbrance,
whether made or created by voluntary act of Employee or any agent of Employee or
by operation of law, shall be recognized by, or be binding upon, or shall in any
manner affect the rights of, the Company or any agent or any custodian holding
certificates for the Restricted Shares during the Restricted Period, unless the
Restrictions have then expired pursuant to the provisions of paragraphs (f) or
(g) below. This provision shall not prohibit Employee from granting revocable
proxies in customary form to vote the Shares.

           (e) If the status of employment (hereinafter referred to as
"employment") of Employee with the Company or its Affiliates (as defined in
Section 6 herein) shall terminate, prior to the expiration of the Restricted
Period as set forth in paragraphs (a), (f) or (g) of this Section then, in that
event, the right to have the Restricted Shares delivered pursuant to paragraph
(b) above and any Restricted Shares outstanding shall, upon such termination of
employment, be forfeited by Employee to the Company, without the payment of any
consideration or further consideration by the Company, and neither Employee nor
any successors, heirs, assigns, or legal representatives of Employee shall
thereafter have any further rights or interest in the Restricted Shares or
certificates therefor, and Employee's name shall thereupon be deleted from the
list of the Company's stockholders with respect to the Restricted Shares.

           (f) If the employment of Employee with the Company or its Affiliates
shall terminate by reason of death or disability, any Restrictions on the
Restricted Shares shall be deemed to have expired as to the Restricted Shares as
of the date of any such occurrence, and the Restricted Shares shall thereafter
be Transferable Shares. For purposes of this Agreement, "disability" means the
inability of Employee to perform the essential requirements of his or her job
with or without reasonable accommodation.

           (g) Upon the occurrence of a Change of Control (as defined herein),
any Restrictions on the Restricted Shares set forth in this Agreement shall be
deemed to have expired, and the Restricted Shares shall thereafter be
Transferable Shares. A "Change of 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
of Form 8-K (or any successor item of Form 8-K or any similar item of any other
report required to be filed by the Company under the Securities Exchange Act of
1934, as amended ("1934 Act")); (ii) any "person" (as such term is used in
Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the 1934 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 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.

           (h) If the employment of Employee with the Company shall terminate
prior to the expiration of the Restricted Period, and there exists a dispute
between Employee and the Company as to the satisfaction of the conditions to the
release of the Shares from the Restrictions hereunder or the terms and
conditions of the Grant, the Shares shall remain subject to the Restrictions
until the resolution of such dispute, regardless of any intervening expiration
of the Restricted Period, except that any dividends that may be payable to the
holders of record of Common Stock as of a date during the period from
termination of Employee's employment to the resolution of such dispute shall:

                (1) to the extent to which such dividends would have been
           payable to Employee on the Shares, be held by the Company as part of
           its general funds, and shall be paid to or for the account of
           Employee only upon, and in the event of, a resolution of such dispute
           in a manner favorable to Employee, and

                (2) be canceled upon, and in the event of, a resolution of such
           dispute in a manner unfavorable to Employee.

      3. Taxes. To the extent that the receipt of the Restricted Shares,
Transferable Shares, or the lapse of any Restrictions results in income to
Employee for federal or state income tax purposes, Employee shall deliver to the
Company at the time of such receipt or lapse, as the case may be, such amount of
money or, if the Company so determines, shares of unrestricted Common Stock as
the Company may require to meet its obligation under applicable tax laws or
regulations, and if Employee fails to do so, the Company is authorized to
withhold from any cash or Common Stock remuneration then or thereafter payable
to Employee any tax required to be withheld by reasons of such resulting
compensation income. Employee agrees to notify the Company promptly of any tax
election made by Employee with respect to the Shares.

      4.   Changes in Capital Structure.  If at any time:
           ----------------------------

           (a) after the Effective Date and prior to the date on which the
Company issues or delivers to Employee certificates representing the Shares as
set forth in paragraph 2(b), the Company shall :

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock which would have
           been issued to Employee as a dividend with respect to the Shares if
           certificates representing the Shares had been issued or delivered to
           Employee on the Effective Date, and such additional shares of capital
           stock shall be issued or delivered to Employee contemporaneously with
           the issuance or delivery to Employee of the Shares, and shall be
           subject to the Restrictions to the same extent as the Shares, and (B)
           with respect to a dividend payable in cash or property other than
           shares of capital stock, an amount of cash or such other property
           equal to the amount of cash or other property which would have been
           paid or delivered to Employee if certificates representing the Shares
           had been issued or delivered to Employee on the Effective Date shall
           be paid or delivered to Employee as compensation income

           which the Common Stock has been split, combined, reclassified or
           changed or exchanged in such transaction, as if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities into which the Common
           Stock shall have been split, combined, reclassified or changed or
           exchanged in such transaction shall be issued or delivered to
           Employee in lieu of the Shares, and shall be subject to the
           Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then

           number and kind of shares of capital stock or other securities which
           Employee would have received in such transaction if certificates

           had been issued or delivered on the Effective Date shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares.

      (b)  after the  issuance  or delivery of  certificates  representing  the
Shares the Company shall:

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock issued to Employee
           as a dividend with respect to the Shares, and such additional shares
           of capital stock shall be issued or delivered to Employee
           contemporaneously with the issuance or delivery to Employee of the
           Shares, and shall be subject to the Restrictions to the same extent
           as the Shares, and (B) with respect to a dividend payable in cash or
           property other than shares of capital stock, the amount of cash or
           other property constituting the amount of the dividend with respect
           to the Shares shall be paid or delivered to Employee
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a
           different number or kind of shares of capital stock or other
           securities, or if the Company shall complete a recapitalization in
           which the Common Stock shall be changed or exchanged into a different
           number or kind of shares of capital stock or other securities, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been split, combined, reclassified or changed or exchanged in such
           transaction, and at such time as the Shares would otherwise be
           issuable or deliverable under this Agreement, certificates
           representing the shares of capital stock or other securities into
           which the Common Stock shall have been split, combined, reclassified

           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been converted in the merger or consolidation, and at such time as

           Shares.

      5.   Compliance With Securities Laws.
           -------------------------------

           (a) Employee represents and warrants to the Company that Employee is
acquiring the Shares for his own account, for investment, and without a view to
any sale or distribution thereof in violation of any federal or state securities
laws. Employee understands that the grant of the Shares to Employee has not been
registered under the Securities Act of 1933, as amended, or the securities laws
of any state, and, accordingly, that in addition to the other restrictions
placed on the Shares by this Agreement, the Shares may not be offered, sold,
assigned, transferred, exchanged, pledged, hypothecated or otherwise encumbered
in absence of either (a) an effective registration statement under the
Securities Act of 1933, as amended, and applicable state securities laws or (b)
an opinion of counsel satisfactory to the Company that such registration is not
required.

           (b) Employee agrees that, if required by the Company, the
certificates representing the Shares (whether the Shares are Restricted Shares
or Transferable Shares) shall bear a legend in substantially the following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS
      AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED,
      EXCHANGED, PLEDGED, HYPOTHECATED OR OTHERWISE ENCUMBERED IN THE ABSENCE OF
      EITHER (1) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF
      1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS OR (2) AN OPINION
      OF COUNSEL SATISFACTORY TO HOWELL CORPORATION THAT SUCH REGISTRATION IS
      NOT REQUIRED.

            (c) Upon the execution of this Agreement and receipt of any
certificates for the Shares pursuant to this Agreement, Employee (or Employee's
legal representative upon Employee's death or disability) will enter into such
additional written representations, warranties and agreements as the Company may
reasonably request in order to comply with applicable securities laws or with
this Agreement.

      6. Employment Relationship. Employee shall be considered to be in the
employment of the Company as long as he remains as an employee of the Company or
its Affiliates. Any questions as to whether and when there has been a
termination of such employment, and the cause of such termination, shall be
determined by the Company, with the advice of the employing corporation (if an
Affiliate of the Company), and the Company's determination shall be final. For
purposes of this Agreement, "Affiliates" shall mean any "parent corporation" of
the Company and any "subsidiary corporation" of the Company within the meaning
of Sections 424(e) and (f), respectively, of the Internal Revenue Code of 1986,
as amended.

      7. Binding Effect. The terms and conditions hereof shall, in accordance
with their terms, be binding upon, and inure to the benefit of, all successors
of Employee, including, without limitation, Employee's estate and the executors,
administrators, or trustees thereof, heirs and legatees, and any receiver,
trustee in bankruptcy, or representative of creditors of Employee. This
Agreement shall be binding upon and inure to the benefit of any successors to
the Company.

                               HOWELL CORPORATION
                           RESTRICTED STOCK AGREEMENT

      This Restricted Stock Agreement ("Agreement"), entered into on the 11th
day of January 2001 (the "Effective Date"), which is the date on which the Grant
described below was approved by the Stock Option Committee of the Board of
Directors of HOWELL CORPORATION, is between HOWELL CORPORATION, a Delaware
corporation (the "Company"), and Robert T. Moffett (the "Employee").

      WHEREAS, the Company and Employee agree as follows:

      1. Award of Common Stock. The Company hereby grants (the "Grant") to
Employee Five Thousand (5,000) shares (the "Shares") of common stock, $1.00 par
value, of the Company ("Common Stock") which shall be subject to the
restrictions on transferability set forth in paragraph 2(d) herein (the
"Restrictions") and to the other provisions of this Agreement. The Shares may be
increased as set forth in paragraph 4 below (such increases to be included in
the term "Shares"), and all such Shares shall be issued to the Employee in
accordance with paragraph 2(b) below.

      2.   Restricted Period.
           -----------------

           (a) For a period of four (4) years commencing on the Effective Date
(the "Restricted Period"), the Shares shall be subject to the Restrictions and
any other restrictions as set forth herein. The Restrictions shall expire as to
all of the Shares on January 11, 2005, the fourth anniversary of the Effective
Date. The Shares which are subject to the Restrictions shall hereinafter be
referred to as "Restricted Shares." The Shares which are no longer subject to
the Restrictions as set forth in this paragraph (a) and in paragraphs (f) or (g)
below shall hereinafter be referred to as "Transferable Shares."

           (b) Prior to the first to occur of (i) a Change of Control (as
defined in paragraph (g) below), (ii) a date which is within ten (10) days of
the Employee's death or disability (as provided in paragraph (f) below) or (iii)
the last day of the Restricted Period, the Company shall issue or transfer to
Employee (or cause to be issued or transferred to Employee), in the manner
hereinafter provided, the Shares. The issuance or transfer may be out of
authorized but unissued shares of Common Stock, or out of treasury shares of
Common Stock, or from an Affiliate (as defined in paragraph 6) of the Company.
Each certificate representing Restricted Shares shall be registered in
Employee's name and shall be either deposited with the Secretary of the Company
or its designee in an escrow account or held by the Secretary of the Company, at
the election of the Company, together with stock powers or other instruments of
transfer appropriately endorsed in blank by Employee (Employee hereby agreeing
to execute such stock powers or other instruments of transfer as requested by
the Company). Such certificate or certificates shall remain in such escrow
account or with the Secretary of the Company until the earlier to occur of (i)
the termination of the Restricted Period or (ii) the expiration of the
Restrictions as set forth in paragraphs (f) or (g) below. Certificates
representing the Restricted Shares shall bear a legend in substantially the
following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THE RESTRICTED STOCK
      AGREEMENT, DATED JANUARY 11, 2001 BETWEEN HOWELL CORPORATION ("COMPANY")
      AND THE REGISTERED HOLDER OF THIS CERTIFICATE. A COPY OF THE FORM OF SUCH
      AGREEMENT IS AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE
      COMPANY AND WILL BE FURNISHED WITHOUT CHARGE TO THE REGISTERED HOLDER OF
      SUCH CERTIFICATE UPON WRITTEN REQUEST.

The Company may place appropriate stop transfer instructions with respect to the
Restricted Shares with the transfer agent for the Common Stock. Upon Restricted
Shares becoming Transferable Shares, the Company shall deliver, in exchange for
the legended certificates, a certificate or certificates for such Shares to the
Employee free of the legend set forth above.

           (c) Subject to the terms of this Agreement, upon the Company's
issuance or delivery of certificates representing the Shares pursuant to
paragraph (b) above, the Employee shall, during the Restricted Period, have all
of the rights of a stockholder with respect to the Shares including, but not
limited to, the right to receive dividends, if any, as may be declared on such
Restricted Shares from time to time, and the right to vote (in person or by
proxy) such Restricted Shares at any meeting of shareholders of the Company.

           (d) The Restricted Shares, the right to receive certificates
representing the Restricted Shares and the right to vote the Restricted Shares
and to receive dividends thereon, may not be sold, assigned, transferred,
exchanged, pledged, hypothecated, or otherwise encumbered and no such purported
sale, assignment, transfer, exchange, pledge, hypothecation, or encumbrance,
whether made or created by voluntary act of Employee or any agent of Employee or
by operation of law, shall be recognized by, or be binding upon, or shall in any
manner affect the rights of, the Company or any agent or any custodian holding
certificates for the Restricted Shares during the Restricted Period, unless the
Restrictions have then expired pursuant to the provisions of paragraphs (f) or
(g) below. This provision shall not prohibit Employee from granting revocable
proxies in customary form to vote the Shares.

           (e) If the status of employment (hereinafter referred to as
"employment") of Employee with the Company or its Affiliates (as defined in
Section 6 herein) shall terminate, prior to the expiration of the Restricted
Period as set forth in paragraphs (a), (f) or (g) of this Section then, in that
event, the right to have the Restricted Shares delivered pursuant to paragraph
(b) above and any Restricted Shares outstanding shall, upon such termination of
employment, be forfeited by Employee to the Company, without the payment of any
consideration or further consideration by the Company, and neither Employee nor
any successors, heirs, assigns, or legal representatives of Employee shall
thereafter have any further rights or interest in the Restricted Shares or
certificates therefor, and Employee's name shall thereupon be deleted from the
list of the Company's stockholders with respect to the Restricted Shares.

           (f) If the employment of Employee with the Company or its Affiliates
shall terminate by reason of death or disability, any Restrictions on the
Restricted Shares shall be deemed to have expired as to the Restricted Shares as
of the date of any such occurrence, and the Restricted Shares shall thereafter
be Transferable Shares. For purposes of this Agreement, "disability" means the
inability of Employee to perform the essential requirements of his or her job
with or without reasonable accommodation.

           (g) Upon the occurrence of a Change of Control (as defined herein),
any Restrictions on the Restricted Shares set forth in this Agreement shall be
deemed to have expired, and the Restricted Shares shall thereafter be
Transferable Shares. A "Change of 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
of Form 8-K (or any successor item of Form 8-K or any similar item of any other
report required to be filed by the Company under the Securities Exchange Act of
1934, as amended ("1934 Act")); (ii) any "person" (as such term is used in
Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the 1934 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 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.

           (h) If the employment of Employee with the Company shall terminate
prior to the expiration of the Restricted Period, and there exists a dispute
between Employee and the Company as to the satisfaction of the conditions to the
release of the Shares from the Restrictions hereunder or the terms and
conditions of the Grant, the Shares shall remain subject to the Restrictions
until the resolution of such dispute, regardless of any intervening expiration
of the Restricted Period, except that any dividends that may be payable to the
holders of record of Common Stock as of a date during the period from
termination of Employee's employment to the resolution of such dispute shall:

                (1) to the extent to which such dividends would have been
           payable to Employee on the Shares, be held by the Company as part of
           its general funds, and shall be paid to or for the account of
           Employee only upon, and in the event of, a resolution of such dispute
           in a manner favorable to Employee, and

                (2) be canceled upon, and in the event of, a resolution of such
           dispute in a manner unfavorable to Employee.

      3. Taxes. To the extent that the receipt of the Restricted Shares,
Transferable Shares, or the lapse of any Restrictions results in income to
Employee for federal or state income tax purposes, Employee shall deliver to the
Company at the time of such receipt or lapse, as the case may be, such amount of
money or, if the Company so determines, shares of unrestricted Common Stock as
the Company may require to meet its obligation under applicable tax laws or
regulations, and if Employee fails to do so, the Company is authorized to
withhold from any cash or Common Stock remuneration then or thereafter payable
to Employee any tax required to be withheld by reasons of such resulting
compensation income. Employee agrees to notify the Company promptly of any tax
election made by Employee with respect to the Shares.

      4.   Changes in Capital Structure.  If at any time:
           ----------------------------

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock which would have
           been issued to Employee as a dividend with respect to the Shares if

           Employee on the Effective Date, and such additional shares of capital
           stock shall be issued or delivered to Employee contemporaneously with

           subject to the Restrictions to the same extent as the Shares, and (B)
           with respect to a dividend payable in cash or property other than
           shares of capital stock, an amount of cash or such other property
           equal to the amount of cash or other property which would have been
           paid or delivered to Employee if certificates representing the Shares
           had been issued or delivered to Employee on the Effective Date shall
           be paid or delivered to Employee as compensation income
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

           number or kind of shares of capital stock or other securities, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities into
           which the Common Stock has been split, combined, reclassified or
           changed or exchanged in such transaction, as if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities into which the Common
           Stock shall have been split, combined, reclassified or changed or
           exchanged in such transaction shall be issued or delivered to
           Employee in lieu of the Shares, and shall be subject to the

           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities which would have been
           issuable in respect of the Shares in such transaction if the Shares
           had been issued or delivered on the Effective Date shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares.

           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock issued to Employee
           as a dividend with respect to the Shares, and such additional shares
           of capital stock shall be issued or delivered to Employee
           contemporaneously with the issuance or delivery to Employee of the
           Shares, and shall be subject to the Restrictions to the same extent
           as the Shares, and (B) with respect to a dividend payable in cash or
           property other than shares of capital stock, the amount of cash or
           other property constituting the amount of the dividend with respect
           to the Shares shall be paid or delivered to Employee
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a
           different number or kind of shares of capital stock or other
           securities, or if the Company shall complete a recapitalization in
           which the Common Stock shall be changed or exchanged into a different
           number or kind of shares of capital stock or other securities, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been split, combined, reclassified or changed or exchanged in such
           transaction, and at such time as the Shares would otherwise be
           issuable or deliverable under this Agreement, certificates
           representing the shares of capital stock or other securities into
           which the Common Stock shall have been split, combined, reclassified
           or changed or exchanged in such transaction shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been converted in the merger or consolidation, and at such time as
           the Shares would otherwise be issuable or deliverable under this
           Agreement, certificates representing the shares of capital stock or
           other securities into which the Common Stock has been converted in
           the merger or consolidation shall be issued or delivered to Employee,
           and shall be subject to the Restrictions to the same extent as the
           Shares.

      5.   Compliance With Securities Laws.
           -------------------------------

           (a) Employee represents and warrants to the Company that Employee is
acquiring the Shares for his own account, for investment, and without a view to
any sale or distribution thereof in violation of any federal or state securities
laws. Employee understands that the grant of the Shares to Employee has not been
registered under the Securities Act of 1933, as amended, or the securities laws
of any state, and, accordingly, that in addition to the other restrictions
placed on the Shares by this Agreement, the Shares may not be offered, sold,
assigned, transferred, exchanged, pledged, hypothecated or otherwise encumbered
in absence of either (a) an effective registration statement under the
Securities Act of 1933, as amended, and applicable state securities laws or (b)
an opinion of counsel satisfactory to the Company that such registration is not
required.

           (b) Employee agrees that, if required by the Company, the
certificates representing the Shares (whether the Shares are Restricted Shares
or Transferable Shares) shall bear a legend in substantially the following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS
      AND, ACCORDINGLY, MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED,
      EXCHANGED, PLEDGED, HYPOTHECATED OR OTHERWISE ENCUMBERED IN THE ABSENCE OF
      EITHER (1) AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF
      1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS OR (2) AN OPINION
      OF COUNSEL SATISFACTORY TO HOWELL CORPORATION THAT SUCH REGISTRATION IS
      NOT REQUIRED.

            (c) Upon the execution of this Agreement and receipt of any
certificates for the Shares pursuant to this Agreement, Employee (or Employee's
legal representative upon Employee's death or disability) will enter into such
additional written representations, warranties and agreements as the Company may
reasonably request in order to comply with applicable securities laws or with
this Agreement.

determined by the Company, with the advice of the employing corporation (if an
Affiliate of the Company), and the Company's determination shall be final. For
purposes of this Agreement, "Affiliates" shall mean any "parent corporation" of
the Company and any "subsidiary corporation" of the Company within the meaning

as amended.

      7. Binding Effect. The terms and conditions hereof shall, in accordance
with their terms, be binding upon, and inure to the benefit of, all successors
of Employee, including, without limitation, Employee's estate and the executors,

trustee in bankruptcy, or representative of creditors of Employee. This
Agreement shall be binding upon and inure to the benefit of any successors to
the Company.

                               HOWELL CORPORATION
                           RESTRICTED STOCK AGREEMENT

      This Restricted Stock Agreement ("Agreement"), entered into on the 11th
day of January 2001 (the "Effective Date"), which is the date on which the Grant
described below was approved by the Stock Option Committee of the Board of
Directors of HOWELL CORPORATION, is between HOWELL CORPORATION, a Delaware
corporation (the "Company"), and Allyn R. Skelton, II (the "Employee").

      WHEREAS, the Company and Employee agree as follows:

      1. Award of Common Stock. The Company hereby grants (the "Grant") to
Employee Five Thousand (5,000) shares (the "Shares") of common stock, $1.00 par
value, of the Company ("Common Stock") which shall be subject to the
restrictions on transferability set forth in paragraph 2(d) herein (the
"Restrictions") and to the other provisions of this Agreement. The Shares may be
increased as set forth in paragraph 4 below (such increases to be included in
the term "Shares"), and all such Shares shall be issued to the Employee in
accordance with paragraph 2(b) below.

      2.   Restricted Period.
           -----------------

           (a) For a period of four (4) years commencing on the Effective Date
(the "Restricted Period"), the Shares shall be subject to the Restrictions and
any other restrictions as set forth herein. The Restrictions shall expire as to
all of the Shares on January 11, 2005, the fourth anniversary of the Effective
Date. The Shares which are subject to the Restrictions shall hereinafter be
referred to as "Restricted Shares." The Shares which are no longer subject to
the Restrictions as set forth in this paragraph (a) and in paragraphs (f) or (g)
below shall hereinafter be referred to as "Transferable Shares."

           (b) Prior to the first to occur of (i) a Change of Control (as
defined in paragraph (g) below), (ii) a date which is within ten (10) days of
the Employee's death or disability (as provided in paragraph (f) below) or (iii)
the last day of the Restricted Period, the Company shall issue or transfer to
Employee (or cause to be issued or transferred to Employee), in the manner
hereinafter provided, the Shares. The issuance or transfer may be out of
authorized but unissued shares of Common Stock, or out of treasury shares of
Common Stock, or from an Affiliate (as defined in paragraph 6) of the Company.
Each certificate representing Restricted Shares shall be registered in
Employee's name and shall be either deposited with the Secretary of the Company
or its designee in an escrow account or held by the Secretary of the Company, at
the election of the Company, together with stock powers or other instruments of
transfer appropriately endorsed in blank by Employee (Employee hereby agreeing
to execute such stock powers or other instruments of transfer as requested by
the Company). Such certificate or certificates shall remain in such escrow
account or with the Secretary of the Company until the earlier to occur of (i)
the termination of the Restricted Period or (ii) the expiration of the
Restrictions as set forth in paragraphs (f) or (g) below. Certificates
representing the Restricted Shares shall bear a legend in substantially the
following form:

           THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      COMPLIANCE WITH THE CONDITIONS SPECIFIED IN THE RESTRICTED STOCK
      AGREEMENT, DATED JANUARY 11, 2001 BETWEEN HOWELL CORPORATION ("COMPANY")
      AND THE REGISTERED HOLDER OF THIS CERTIFICATE. A COPY OF THE FORM OF SUCH
      AGREEMENT IS AVAILABLE FOR INSPECTION AT THE PRINCIPAL OFFICE OF THE
      COMPANY AND WILL BE FURNISHED WITHOUT CHARGE TO THE REGISTERED HOLDER OF
      SUCH CERTIFICATE UPON WRITTEN REQUEST.

The Company may place appropriate stop transfer instructions with respect to the
Restricted Shares with the transfer agent for the Common Stock. Upon Restricted
Shares becoming Transferable Shares, the Company shall deliver, in exchange for
the legended certificates, a certificate or certificates for such Shares to the
Employee free of the legend set forth above.

           (c) Subject to the terms of this Agreement, upon the Company's
issuance or delivery of certificates representing the Shares pursuant to
paragraph (b) above, the Employee shall, during the Restricted Period, have all
of the rights of a stockholder with respect to the Shares including, but not
limited to, the right to receive dividends, if any, as may be declared on such
Restricted Shares from time to time, and the right to vote (in person or by
proxy) such Restricted Shares at any meeting of shareholders of the Company.

           (d) The Restricted Shares, the right to receive certificates
representing the Restricted Shares and the right to vote the Restricted Shares
and to receive dividends thereon, may not be sold, assigned, transferred,
exchanged, pledged, hypothecated, or otherwise encumbered and no such purported
sale, assignment, transfer, exchange, pledge, hypothecation, or encumbrance,
whether made or created by voluntary act of Employee or any agent of Employee or
by operation of law, shall be recognized by, or be binding upon, or shall in any
manner affect the rights of, the Company or any agent or any custodian holding
certificates for the Restricted Shares during the Restricted Period, unless the
Restrictions have then expired pursuant to the provisions of paragraphs (f) or
(g) below. This provision shall not prohibit Employee from granting revocable
proxies in customary form to vote the Shares.

           (e) If the status of employment (hereinafter referred to as
"employment") of Employee with the Company or its Affiliates (as defined in
Section 6 herein) shall terminate, prior to the expiration of the Restricted
Period as set forth in paragraphs (a), (f) or (g) of this Section then, in that
event, the right to have the Restricted Shares delivered pursuant to paragraph
(b) above and any Restricted Shares outstanding shall, upon such termination of
employment, be forfeited by Employee to the Company, without the payment of any
consideration or further consideration by the Company, and neither Employee nor
any successors, heirs, assigns, or legal representatives of Employee shall
thereafter have any further rights or interest in the Restricted Shares or
certificates therefor, and Employee's name shall thereupon be deleted from the
list of the Company's stockholders with respect to the Restricted Shares.

           (f) If the employment of Employee with the Company or its Affiliates
shall terminate by reason of death or disability, any Restrictions on the
Restricted Shares shall be deemed to have expired as to the Restricted Shares as
of the date of any such occurrence, and the Restricted Shares shall thereafter
be Transferable Shares. For purposes of this Agreement, "disability" means the
inability of Employee to perform the essential requirements of his or her job
with or without reasonable accommodation.

           (g) Upon the occurrence of a Change of Control (as defined herein),
any Restrictions on the Restricted Shares set forth in this Agreement shall be
deemed to have expired, and the Restricted Shares shall thereafter be
Transferable Shares. A "Change of 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
of Form 8-K (or any successor item of Form 8-K or any similar item of any other
report required to be filed by the Company under the Securities Exchange Act of
1934, as amended ("1934 Act")); (ii) any "person" (as such term is used in
Sections 13(d) and 14(d)(2) of the 1934 Act) is or becomes the "beneficial
owner" (as defined in Rule 13d-3 under the 1934 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 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.

           (h) If the employment of Employee with the Company shall terminate
prior to the expiration of the Restricted Period, and there exists a dispute
between Employee and the Company as to the satisfaction of the conditions to the
release of the Shares from the Restrictions hereunder or the terms and
conditions of the Grant, the Shares shall remain subject to the Restrictions
until the resolution of such dispute, regardless of any intervening expiration
of the Restricted Period, except that any dividends that may be payable to the
holders of record of Common Stock as of a date during the period from
termination of Employee's employment to the resolution of such dispute shall:

                (1) to the extent to which such dividends would have been
           payable to Employee on the Shares, be held by the Company as part of
           its general funds, and shall be paid to or for the account of
           Employee only upon, and in the event of, a resolution of such dispute
           in a manner favorable to Employee, and

                (2) be canceled upon, and in the event of, a resolution of such
           dispute in a manner unfavorable to Employee.

      3. Taxes. To the extent that the receipt of the Restricted Shares,
Transferable Shares, or the lapse of any Restrictions results in income to
Employee for federal or state income tax purposes, Employee shall deliver to the
Company at the time of such receipt or lapse, as the case may be, such amount of
money or, if the Company so determines, shares of unrestricted Common Stock as
the Company may require to meet its obligation under applicable tax laws or
regulations, and if Employee fails to do so, the Company is authorized to
withhold from any cash or Common Stock remuneration then or thereafter payable
to Employee any tax required to be withheld by reasons of such resulting
compensation income. Employee agrees to notify the Company promptly of any tax
election made by Employee with respect to the Shares.

      4.   Changes in Capital Structure.  If at any time:
           ----------------------------

           (a) after the Effective Date and prior to the date on which the
Company issues or delivers to Employee certificates representing the Shares as
set forth in paragraph 2(b), the Company shall :

                (1) declare a dividend or other distribution in respect of the
           Common Stock payable in shares of capital stock, cash or other
           property, then and in each such case (A) with respect to a dividend
           payable in shares of capital stock, the number of Shares shall be
           increased by the number of shares of capital stock which would have
           been issued to Employee as a dividend with respect to the Shares if
           certificates representing the Shares had been issued or delivered to
           Employee on the Effective Date, and such additional shares of capital
           stock shall be issued or delivered to Employee contemporaneously with
           the issuance or delivery to Employee of the Shares, and shall be
           subject to the Restrictions to the same extent as the Shares, and (B)
           with respect to a dividend payable in cash or property other than
           shares of capital stock, an amount of cash or such other property
           equal to the amount of cash or other property which would have been
           paid or delivered to Employee if certificates representing the Shares
           had been issued or delivered to Employee on the Effective Date shall
           be paid or delivered to Employee as compensation income
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

           number or kind of shares of capital stock or other securities, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities into
           which the Common Stock has been split, combined, reclassified or
           changed or exchanged in such transaction, as if certificates
           representing the Shares had been issued or delivered on the Effective

           Stock shall have been split, combined, reclassified or changed or
           exchanged in such transaction shall be issued or delivered to
           Employee in lieu of the Shares, and shall be subject to the
           Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           and in each such case the Shares shall thereafter represent the
           number and kind of shares of capital stock or other securities which
           Employee would have received in such transaction if certificates
           representing the Shares had been issued or delivered on the Effective
           Date, and at such time as the Shares would otherwise be issuable or
           deliverable under this Agreement, certificates representing the
           shares of capital stock or other securities which would have been
           issuable in respect of the Shares in such transaction if the Shares
           had been issued or delivered on the Effective Date shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares.

      (b)  after the  issuance  or delivery of  certificates  representing  the
Shares the Company shall:

           increased by the number of shares of capital stock issued to Employee
           as a dividend with respect to the Shares, and such additional shares
           of capital stock shall be issued or delivered to Employee
           contemporaneously with the issuance or delivery to Employee of the
           Shares, and shall be subject to the Restrictions to the same extent
           as the Shares, and (B) with respect to a dividend payable in cash or
           property other than shares of capital stock, the amount of cash or
           other property constituting the amount of the dividend with respect
           to the Shares shall be paid or delivered to Employee
           contemporaneously with the payment or delivery of the dividend to the
           Company's stockholders;

                (2) split, combine or reclassify the Common Stock into a
           different number or kind of shares of capital stock or other
           securities, or if the Company shall complete a recapitalization in
           which the Common Stock shall be changed or exchanged into a different
           number or kind of shares of capital stock or other securities, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has
           been split, combined, reclassified or changed or exchanged in such
           transaction, and at such time as the Shares would otherwise be
           issuable or deliverable under this Agreement, certificates
           representing the shares of capital stock or other securities into
           which the Common Stock shall have been split, combined, reclassified
           or changed or exchanged in such transaction shall be issued or
           delivered to Employee in lieu of the Shares, and shall be subject to
           the Restrictions to the same extent as the Shares; or

                (3) be merged or consolidated with or into another person, then
           the Shares shall thereafter represent the number and kind of shares
           of capital stock or other securities into which the Common Stock has

           Shares.

      5.   Compliance With Securities Laws.
           -------------------------------

           (a) Employee represents and warrants to the Company that Employee is
acquiring the Shares for his own account, for investment, and without a view to
any sale or distribution thereof in violation of any federal or state securities
laws. Employee understands that the grant of the Shares to Employee has not been
registered under the Securities Act of 1933, as amended, or the securities laws
of any state, and, accordingly, that in addition to the other restrictions
placed on the Shares by this Agreement, the Shares may not be offered, sold,
assigned, transferred, exchanged, pledged, hypothecated or otherwise encumbered
in absence of either (a) an effective registration statement under the
Securities Act of 1933, as amended, and applicable state securities laws or (b)
an opinion of counsel satisfactory to the Company that such registration is not
required.

           (b) Employee agrees that, if required by the Company, the
