FORM OF NONQUALIFIED STOCK OPTION AGREEMENT


     THIS  AGREEMENT  entered into on [ ], but effective as of[ ] by and between
Vulcan Minerals & Energy,  Inc., a Texas  corporation (the  "Company"),  and [ ]
(the  "Option  Holder"),  relating  to an option to  purchase  [ ] shares of the
Company's common stock, par value $0.01 per share (the "Common Stock").

     1.  Grant of  Option.  The  Company  hereby  grants  to the  Option  Holder
effective  as of June 2, 2000 (the  "Grant  Date") an option (the  "Option")  to
purchase  40,000 shares of Common  Stock.  The Option shall be  exercisable,  in
whole or in part as to any vested portion thereof, at an exercise price of $[  ]
per share (the "Option  Price").  The Option shall be  exercisable in increments
ratably as set forth in Exhibit A hereto (the "Vesting Schedule")  determined by
the number of full years of service as an  employee  or  director of the Company
from the date of grant to the date of exercise.

     Notwithstanding  anything in this  Agreement to the  contrary,  the Vesting
Schedule  is subject to Section 4 herein.  The Board of  Directors,  in its sole
discretion,  may waive the Vesting  Schedule  and,  upon  written  notice to the
Option Holder, accelerate the earliest date or dates in which any of the Options
granted hereunder are exercisable. This Agreement and the purchase of the shares
of Common  Stock  hereunder is not  intended  and should not be  interpreted  to
qualify as an Incentive  Stock Option as that term is used in Section 422 of the
Internal  Revenue  Code of 1986,  as it may be  amended  from  time to time (the
"Internal Revenue Code").

     2. Method for Exercising  the Option.  The vested portion of the option may
be exercised in whole or in part only by delivery in person or through certified
or  registered  mail to the Company at its  principal  office in Houston,  Texas
(attention: Corporate Secretary) of written notice specifying the Option that is
being  exercised  and the number of shares of Common Stock with respect to which
the Option is being exercised.  The notice must be accompanied by payment of the
total Option Price.

     The total Option Price for the Common Stock to be acquired  pursuant to the
Option shall be paid in full by any of the following  methods or any combination
of the following methods:

(a)  In cash or by certified or cashier's  check  payable to the order of Vulcan
     Minerals & Energy, Inc.;

(b)  The  delivery to the  Company of  certificates  representing  the number of
     shares of Common  Stock  then owned by the Option  Holder,  the  Designated
     Value (defined  below) of which equals the Option Price of the Common Stock
     purchased  pursuant to the Option,  properly  endorsed  for transfer to the
     Company; provided,  however, that no Option may be exercised by delivery to
     the Company of  certificates  representing  Common Stock unless such Common
     Stock has been held by the  Option  Holder for more than six  months.  (For
     purposes of this  Agreement,  the Designated  Value of any shares of Common
     Stock  delivered in payment of the Option Price upon exercise of the Option
     shall be the  Designated  Value as of the exercise  date,  and the exercise
     date shall be the day of delivery of the  certificates for the Common Stock
     used as payment of the Option Price);


(c)  By  delivery  to the  Company of a properly  executed  notice of  exercise,
     together with irrevocable  instructions to a broker to delivery promptly to
     the  Company,  in  payment  of the  Option  Price,  the  amount of the cash
     proceeds of the sale of shares of Common Stock or a loan from the broker to
     the Option Holder sufficient, in each case, to pay the Option Price, and in
     a form satisfactory to the Corporate Secretary; or

(d)  By delivery to the Company of  sufficient  Options,  properly  endorsed for
     transfer to the Company,  having a value sufficient to pay the Option Price
     with  respect  to the other  Options  that are to be  exercised  under this
     Agreement.  The value of each  Option to be  surrendered  in payment of the
     Option Price shall be determined by  subtracting  the Option Price from the
     Designated Value as of the date of receipt of notice of the exercise of the
     Options by the Corporate Secretary.

     Upon such notice to the Corporate Secretary and payment of the total Option
Price,  the  exercise  of the  Option  shall be  deemed to be  effective,  and a
properly executed  certificate or certificates  representing the Common Stock so
purchased shall be issued by the Company and delivered to the Option Holder.

     For purposes of this  Agreement,  the  "Designated  Value" of the shares of
Common  Stock on a given date  shall  mean (i) if the Common  Stock is listed or
admitted for trading on any national  securities exchange or the National Market
System  of the  National  Association  of  Securities  Dealers,  Inc.  Automated
Quotation System, the last sale price, or if no sale occurred,  the mean between
the closing high bid and low asked  quotations for such date of the Common Stock
on the principal securities exchange on which shares of Common Stock are listed,
(ii) if Common  Stock is not traded on any national  securities  exchange but is
quoted  on the  National  Association  of  Securities  Dealers,  Inc.  Automated
Operations  System,  or  any  similar  system  of  automated   dissemination  of
quotations or securities prices in common use, the mean between the closing high
bid and low asked  quotations  for such day of the Common  Stock on such system,
(iii) if neither  clause (i) nor (ii) is  applicable,  the mean between the high
bid and low asked  quotations  for the Common  Stock as reported by the National
Quotation  Bureau  Incorporated  if at least two securities  deals have inserted
both bid and asked  quotations  for shares of the Common  Stock on at least five
(5) of the ten (10) preceding  days, or (iv) if none of the conditions set forth
above is met, the fair market value of shares of Common Stock as  determined  by
the Board.  Provided,  for purposes of  determining  "fair market  value" of the
Common Stock of the Company,  such value shall be determined  without  regard to
any  restriction  other than a restriction  which will never lapse.  In no event
shall the fair market value of the Common Stock be less than its par value.


     3. Adjustment of the Option.

          (a) Adjustment by Stock Split, Stock Dividend,  Etc. If at anytime the
     Company  increases or  decreases  the number of its  outstanding  shares of
     Common Stock, or changes in any way the rights and privileges of its Common
     Stock by means of

          (i)  the  payment  of a stock  dividend  or the  making  of any  other
               distribution on such shares payable in Common Stock;

          (ii) through a stock split or  subdivision  of shares of Common stock,
               or a consolidation or combination of shares of Common Stock; or

          (iii)through a  reclassification  or  recapitalization  involving  the
               Common Stock,

     then the  numbers,  rights and  privileges  of the  shares of Common  Stock
included in the Option shall be increased, deceased or changed in like manner as
if such shares of Common Stock had been issued and  outstanding,  fully paid and
non-assessable at the time of such occurrence.

          (b) Other  Changes in Stock.  In the event there is any change,  other
     than as specified in the preceding subsection 3(a) in the number or kind of
     outstanding shares of Common Stock or of any stock or other securities into
     which the Common Stock is changed or for which it has been exchanged,  then
     and if the Board of Directors of the Company, in its discretion, determines
     that such change equitably  requires an adjustment in the number or kind of
     shares subject to the Option,  such adjustments  shall be made by the Board
     of Directors and shall be effective for all purposes as of this Agreement.

          (c)  Apportionment of Option Price.  Upon any occurrence  described in
     the preceding  subsections 3(a) and (b), the aggregate Option Price for the
     shares of Common Stock then  subject to the Option  shall remain  unchanged
     and shall be apportioned  ratably over the increased or decreased number or
     changed kinds of securities or other properties subject to the Option.

          4. Change of Control; Termination with Cause; Corporate Transactions.

          (a) In the event of a Change of Control (as  defined in the  Company's
     1997 Incentive Stock Option Plan (the "Plan")),  all  outstanding  Options,
     whether  exercisable or not, shall immediately vest and become  exercisable
     in accordance with Section 6(c) of the Plan.

          (b) In the event the Option  Holder's  service  as [ ] of the  Company
     terminates due to: (i) Option Holder being  convicted of a crime  involving
     fraud  against  the  Company  or any  of its  affiliates  or the  theft  or
     embezzlement  by  Option  Holder of  assets  of the  Company  or any of its
     affiliates;  or (ii) the conviction of, or the entering of a guilty plea or
     no contest plea by Option Holder for a crime involving felony by a court of
     competent  jurisdiction;  then, in any such event, all outstanding Options,
     whether exercisable or not, shall expire on the date of termination.


          (c) If the  Company  recapitalizes  or  otherwise  changes its capital
     structure, or merges,  consolidates,  sells all of its assets or dissolves,
     and such  transaction is not a Change of Control,  then thereafter upon any
     exercise of the Option  hereunder,  the Option  Holder shall be entitled to
     purchase under the Option,  in lieu of the number of shares of Common Stock
     covered by this Option then exercisable,  the number and class of shares of
     stock and  securities  to which the Option  Holder would have been entitled
     pursuant to the terms of the  agreement of merger,  consolidation,  sale of
     assets or dissolution,  if,  immediately prior to such agreement of merger,
     consolidation,  sale of assets or  dissolution,  the Option Holder had been
     the  holder of record of the  number of shares of Common  Stock as to which
     the Option is then exercisable.

     5.  Expiration and  Termination  of the Option.  The Option shall expire at
5:00 p.m.  Houston,  Texas, time on the tenth anniversary of the Grant Date (the
period from the date of this Agreement to the expiration  date is defined as the
"Option Period") or prior to such time as follows:

     Upon  termination of Option  Holder's  services to the Company by reason of
the death of the Option Holder,  the Options shall be exercisable as of the date
of the Option  Holder's death and may be exercised by the Option Holder's estate
or by the person who  acquired  the right to  exercise  the Option by bequest or
inheritance. Such Options shall not be exercisable after the date they expire or
more than one year from the date of the Option Holder's  death,  whichever first
occurs.

     6.  Transferability.  The Option may not be  transferred  except by will or
pursuant to the laws of descent and  distribution,  and it shall be  exercisable
during the Option  Holder's life only by him, or in the event of his  disability
or incapacity, by his personal representative,  and after his death, only by his
estate or by the person who acquired the right to exercise the Option by bequest
or inheritance.

     7.  Compliance  with  Securities  Laws.  Upon the acquisition of any shares
pursuant to the  exercise of the Option  herein  granted,  Option  Holder or any
person acting under  Section 5(b) will enter into such written  representations,
warranties  and  agreements  as the company may  reasonably  request in order to
comply with applicable securities laws or with this Agreement.

     8. Legends on  Certificates.  The  Certificates  representing the shares of
Common  Stock  purchased  by exercise of an Option will be stamped or  otherwise
imprinted  with  legends in such form as the  Company or its counsel may require
with respect to any  applicable  restrictions  on sale or transfer and the stock
transfer records of the Company will reflect  stock-transfer  instructions  with
respect to such shares.


     9. Withholding.

          (a)  Arrangement for  Withholding.  The Option Holder hereby agrees to
     make appropriate arrangements with the Company to provide for the amount of
     tax withholding, if any, under applicable federal and state income tax laws
     resulting  from the exercise of the Option.  If such  arrangements  are not
     made,  the  Company  may  refuse to issue any  Common  Stock to the  Option
     Holder.

          (b) Withholding Election.  The Option Holder may elect to pay all such
     amounts of tax withholding, or any part thereof, by electing to transfer to
     the Company, or to have the Company withhold from shares otherwise issuable
     to the Option  Holder,  shares of Common  Stock having a value equal to the
     amount  required to be withheld or such lesser  amount as may be elected by
     the Option  Holder.  All  elections  shall be subject  to the  approval  or
     disapproval of the Board of Directors.  The value of shares of Common Stock
     to be withheld shall be based on the  Designated  Value of the Common Stock
     on the date that the amount of tax to be withheld is to be determined  (the
     "Tax  Date").  Any such  election  by the Option  Holder to have  shares of
     Common Stock  withheld  for this  purpose will be subject to the  following
     restrictions:

          (i) All elections must be made prior to the Tax Date.

          (ii) All elections shall be irrevocable.

          (iii)If  the Option  Holder is an officer or  director  of the Company
     within the meaning of Section 16 of the Securities Exchange Act of 1934, as
     amended, ("Section 16"), the Option Holder must satisfy the requirements of
     such Section 16 and any applicable rules thereunder with respect to the use
     of  Common  Stock  as   consideration   to  satisfy  such  tax  withholding
     obligation.

          10. Registration of Common Stock.

     Should Vulcan become a publicly  traded entity,  the Company will undertake
to register  the Common Stock to be acquired  pursuant to this Option  Agreement
for trading on a national  securities exchange or the National Market Securities
Dealers,  Inc. If, at the time Options under this Agreement  become vested,  and
the Company has not  completed  the  registration  process,  the  Company,  upon
written notice,  will purchase in cash within five (5) days of receipt of notice
from  Option  Holder,  the Common  Stock  acquired  by the Option  Holder at the
"Designated Value" as set forth in paragraph 2 of this Agreement.


          11. Miscellaneous.

          (a) Notices.  Any notice  required or permitted to be given under this

          (b)  Amendment.  The Board of Directors may make any adjustment in the
     Option Price, the number of shares of Common Stock subject to, or the terms
     of the Option by amendment or by  substitution  of an  outstanding  Option.

     rights and  obligations  of the Option  Holder  with  respect to the Common
     Stock and the Option.
