                             PETROCORP INCORPORATED
                             2000 STOCK OPTION PLAN

                              STATEMENT OF PURPOSE

One purpose of the PetroCorp Incorporated 2000 Incentive Stock Compensation Plan
(the "Plan") is to encourage superior  performance by employees of the Company's
management firm  ("employees"),  by allowing the Board of Directors of PetroCorp
Incorporated  ("PEC")  to award  several  forms  of  incentive  compensation  to
employees of the Company. By providing incentive  compensation  commensurate and
competitive with that provided by other  companies,  the Plan should also assist
in attracting and retaining the services of qualified and capable employees.

In order to further the identity of interest of employees with the  stockholders
of PEC,  all of the forms of  compensation  under the Plan  relate to PEC Common
Stock. Employees' success in enhancing stockholder value will translate directly
into an enhanced benefit for the employee.

An additional purpose of the Plan is to encourage the Directors to own shares of
the Company's  stock and thereby to align their  interests more closely with the
interests of the other  stockholders  of PEC, to encourage  the highest level of
Director  performance by providing the Directors with a direct interest in PEC's
attainment of its financial  goals,  and to provide a financial  incentive  that
will help attract and retain the most qualified Directors.

Participant not in good faith and without  reasonable  belief that his action or
omission was in the best interest of the Company.

A    "Change in Control" shall be deemed to have occurred if:

(a)  any  "person,"  as such  term is used in  Section  13(d)  and  14(d) of the
     Securities  Exchange Act of 1934, as amended (the  "Exchange  Act"),  other
     than any trustee or other fiduciary  holding  securities  under an employee
     benefit plan of PEC or any company owned,  directly or  indirectly,  by the
     stockholders  of  PEC  in  substantially  the  same  proportions  as  their
     ownership of stock of PEC, is or becomes the "beneficial owner" (as defined
     in  Rule  13d-3  under  the  Exchange  Act),  directly  or  indirectly,  of
     securities of PEC  representing an additional 25 percentage  points or more
     of  the  combined  voting  power   percentage  of  PEC's  then  outstanding
     securities;

(b)  the  stockholders of PEC approve a merger or  consolidation of PEC with any
     other company other than (i) a merger or  consolidation  which would result
     in the voting  securities  of PEC  outstanding  immediately  prior  thereto
     continuing  to  represent  (either  by  remaining  outstanding  or by being
     converted into voting  securities of the surviving entity) more than 65% of
     the  combined  voting  power  of the  voting  securities  of PEC  (or  such
     surviving   entity)   outstanding   immediately   after   such   merger  or
     consolidation,  or (ii) a merger or  consolidation  effected to implement a
     recapitalization  of PEC (or similar  transaction) in which no "person" (as
     hereinabove  defined)  acquires  more  than  an  additional  25%  ownership
     percentage  of  the  combined  voting  power  of  PEC's  then   outstanding
     securities; or



(c)  the  stockholders  of PEC adopt a plan of  complete  liquidation  of PEC or

     such  other  method  as  the  Board  of  Directors  of  PEC  determines  is
     appropriate  in a case  where  there is no readily  ascertainable  purchase
     price) constitutes more than two-thirds of the fair market value of PEC (as
     hereinafter  defined).  For purposes of the preceding  sentence,  the "fair
     market value of PEC" shall be the aggregate market value of the outstanding
     shares of common stock of PEC (on a fully diluted basis) plus the aggregate
     market value of PEC's other outstanding  equity  securities.  The aggregate
     market  value of the shares of common stock of PEC shall be  determined  by
     multiplying  the number of shares of PEC's common stock (on a fully diluted
     basis)  outstanding  on  the  date  of  the  execution  and  delivery  of a
     definitive  agreement with respect to the  transaction or series of related
     transactions (the  "Transaction  Date") by the average closing price of the
     shares  of  common  stock  of PEC  for  the ten  trading  days  immediately
     preceding the  Transaction  Date.  The aggregate  market value of any other
     equity  securities of PEC shall be  determined in a manner  similar to that
     prescribed  in the  immediately  preceding  sentence  for  determining  the
     aggregate  market  value of the  shares of  common  stock of PEC or by such
     other method as the Board shall determine is appropriate.

III.  ADMINISTRATION OF THE PLAN

The Plan shall be  administered  by the Committee.  The members of the Committee
shall not be eligible to participate in the Plan,  except as provided in Section
XVII. The Committee shall select or may delegate to the President of the Company
the selection of, from time to time,  those employees to be granted Awards under
the Plan. The Committee shall also determine the terms and provisions of Awards,
which need not be identical.  The Committee  shall construe the Plan,  prescribe
and  rescind  rules  and  regulations  relating  to the Plan and make all  other
determinations deemed necessary or advisable for the administration of the Plan,
subject to the limitations of Sections XXI and XXII.


IV.  ELIGIBILITY

Subject to the  discretion of the  Committee,  all officers and key employees of
the Company or the Company managing the Company who have  responsibility for the
growth and profitability of the Company are eligible to receive Awards under the
Plan;  provided,  however, no employee may receive in any calendar year an Award
or Awards of Options and/or Stock Appreciation  Rights with respect to more than
20,000 shares of Common Stock. Directors shall automatically  participate in the
Plan as provided in Section XVII.

V.  OPTIONS

The Committee  may, from time to time and subject to the provisions of the Plan,
grant Awards of Options to employees to purchase shares of Common Stock. All

Options  granted  will be  Incentive  Stock  Options  and will be subject to the
requirements of Section VI of the Plan.

The  purchase  price  of the  Common  Stock  subject  to any  Options  shall  be
determined  by the  Committee.  Such price  shall be subject  to  adjustment  as
provided in Section XIII of the Plan.

Options shall not be  exercisable  prior to the date that is twelve months after
the Grant  Date.  In  addition,  the  Committee  may  include in each  agreement
evidencing the Option grant a provision  stating that the Option granted therein
may not be  exercised  in whole or in part for an  additional  period(s) of time
specified in such  agreement,  and may further limit the  exercisability  of the
Option in such manner as the Committee  deems  appropriate,  including,  without
limitation,  the  achievement  of performance  goals.  The Committee may, in its
discretion,  at any time and from time-to-time  accelerate the exercisability of
all or part of any Option, provided that the Company's shareholders, by majority
vote have approved such  acceleration  unless such  acceleration is specifically
provided for herein.

The period of any Option,  which is the time period  during which the Option may
be  exercised,  shall be  determined  by the Committee and shall not extend more
than ten years after the Grant Date.

Options shall not be transferable  other than by will or the laws of descent and
distribution and during the Participant's  lifetime shall be exercisable only by
the Participant.


Termination  for Cause,  as defined in Section I, shall result in  forfeiture of
all outstanding Options.  Termination for any reason other than Cause (including
terminations  pursuant to formal severance  programs sponsored by the Company or
an affiliate),  or  terminations  by reason of death,  Disability or Retirement,
shall  result  in a  lapse  of all or a  proportion  of  the  Restricted  Period
applicable to any outstanding Award as set forth in Section XI.

A person  electing  to  exercise  an Option  shall give  written  notice of such
election to the Company in such form as the Committee may require. Upon exercise
of an Option,  the full option  purchase  price for the shares  with  respect to
which the Option is being  exercised shall be payable to the Company (i) in cash
or by check  payable  and  acceptable  to the  Company  or (ii)  subject  to the
approval of the  Committee,  (a) by  tendering  to the Company  shares of Common
Stock owned by such person having an aggregate  Fair Market Value as of the date
of exercise and tender that is not greater than the full option  purchase  price
for the shares with respect to which the Option is being exercised and by paying
any  remaining  amount of the option  purchase  price as  provided  in (i) above
(provided  that the  Committee  may, upon  confirming  that such person owns the
number of  additional  shares being  tendered,  authorize  the issuance of a new
certificate for the number of shares being acquired  pursuant to the exercise of
the Option less the number of shares being tendered upon the exercise and return
to such  person (or not require  surrender  of) the  certificate  for the shares
being  tendered  upon the  exercise)  or (b) by such  person  delivering  to the
Company  a  properly   executed   exercise  notice  together  with   irrevocable
instructions  to a broker to  promptly  deliver to the  Company  cash or a check
payable and  acceptable to the Company to pay the option  purchase price and any
withholding  taxes;  provided  that in the event such person  chooses to pay the
option purchase price and withholding  taxes as provided in (ii)(b) above,  such
person and the broker  shall  comply  with such  procedures  and enter into such
agreements of indemnity and other agreements as the Committee shall prescribe as
a condition  of such payment  procedure.  Payment  instruments  will be received
subject to collection.


Notwithstanding  any other  provision in the Plan, if a Change in Control occurs
while  unexercised  Options,  and Stock  Appreciation  Rights relating  thereto,
remain  outstanding  under the Plan, then from and after the Acceleration  Date,
all Options and Stock Appreciation  Rights shall be exercisable in full, whether
or not  otherwise  exercisable;  provided,  however,  that no  Option  or  Stock
Appreciation  Right shall become  exercisable by reason of this paragraph to the
extent that such  acceleration  of  exercisability,  when  aggregated with other
payments or benefits to the Participant pursuant to this Plan or any other plan,
arrangement or agreement with the Company,  any person whose actions result in a
Change in Control  or any person  affiliated  with the  Company or such  person,
would, as determined by tax counsel  selected by the Company,  result in "Excess
Parachute  Payments"  (as defined  below)  equal to or greater  than three times
the"base  amount"  as defined in  Section  280G of the Code.  "Excess  Parachute
Payments" shall mean "parachute payments" as defined in Section 280G of the Code
other than (1) health and life insurance benefits and (2) payments  attributable
to any award,  benefit  or other  compensation  plan or  program  based upon the
number of full or fractional months of any restricted period (relating  thereto)
which has elapsed prior to the date of the Change in Control.  Furthermore, such
payments or benefits  provided to a Participant under this Plan shall be reduced
to the  extent  necessary  so that no  portion  thereof  shall be subject to the
excise tax imposed by Section  4999 of the Code,  but only if, by reason of such
reduction,  the  Participant's  net after tax benefit shall exceed the net after
tax benefit if such reduction were not made.  "Net after tax benefit" shall mean
the sum of (i) all payments and benefits which a Participant receives or is then
entitled to receive from the Company that would constitute a "parachute payment"
within the meaning of Section 280G of the Code,  less (ii) the amount of federal
income taxes payable with respect to the payments and benefits  described in (i)
above  calculated at the maximum marginal income tax rate for each year in which
such payments and benefits shall be paid to the Participant (based upon the rate
for such year as set forth in the Code at the time of the first  payment  of the
foregoing),  less (iii) the amount of excise  taxes  imposed with respect to the
payments and benefits described in (i) above by Section 4999 of the Code.

VI.  INCENTIVE STOCK OPTIONS

An Option designated by the Committee as an "Incentive Stock Option" is intended
to qualify as an "incentive  stock option"  within the meaning of Section 422 of
the Code and shall  satisfy,  in  addition to the  conditions  of Section V, the
conditions set forth in this Section VI.

The  purchase  price of the Common Stock  subject to an  Incentive  Stock Option
shall be the greater of the Fair Market  Value of the Common  Stock on the Grant
Date or the "fair  market  value" of the  Common  Stock as such term is used for
purposes for Section 422(b)(4) of the Code.

An Incentive  Stock Option shall not be granted to an employee who, on the Grant
Date,  owns stock  possessing more than ten percent of the total combined voting
power  of  all  classes  of  stock  of  PEC,  or of  its  parent  or  subsidiary
corporations.


VII.  INTENTIONALLY LEFT BLANK

VIII.  STOCK APPRECIATION RIGHTS

The Committee  may, from time to time and subject to the provisions of the Plan,
grant Awards of Stock Appreciation Rights to employees of the Company subject to
the  limitation  in Section II. An Award of Stock  Appreciation  Rights,  in the
Committee's discretion,  may only be made in tandem with the grant of an Option;
however,   there  is  no  obligation  for  the  committee  to  award  any  Stock
Appreciation Rights in tandem with any grant.

The period of any Stock  Appreciation  Right,  which is the time  period  during
which the Stock Appreciation Right may be exercised,  shall be determined by the
Committee and shall be in tandem with the period of such Option.

Stock  Appreciation  Rights shall not be transferable  other than by will or the
laws of descent and distribution and during the Participant's  lifetime shall be
exercisable only by the Participant.

Termination  for Cause,  as defined in Section I, shall result in  forfeiture of
all outstanding Stock  Appreciation  Rights.  Termination by the Company for any
reason other than Cause  (including  terminations  pursuant to formal  severance
programs sponsored by the Company or an affiliated  company),  or termination by
reason of death,  Disability or Retirement,  shall result in a lapse on all or a
portion of the  Restricted  Period  applicable to any  outstanding  Award as set
forth in Section XI.

Subject to any  restrictions  or conditions  imposed by the Committee,  upon the
exercise of a Stock  Appreciation  Right,  the Company shall pay the amount,  if
any,  by which the Fair Market  Value of a share of Common  Stock on the date of
exercise  exceeds the Fair Market  Value of a share of Common Stock on the Grant
Date.  The  amount  payable  by  the  Company  upon  the  exercise  of  a  Stock
Appreciation Right may be paid in cash less any required government withholdings
with respect to the Stock Appreciation Right and its tandem Option.

X.  CONTINUED EMPLOYMENT

Participation  in the Plan shall confer no rights to continued  employment  with
the  Company,  nor shall it restrict  the rights of the  Company to  terminate a
Participant's employment relationship at any time.

XI.  TERMINATION OF EMPLOYMENT

In the event of a  Participant's  termination of employment  with the Company by
reason of death, the Restricted  Period shall lapse on all of the  Participant's
outstanding Awards.

In the event of a  Participant's  termination of employment  with the Company by
reason of  Disability,  Retirement  or by the Company for any reason  other than
Cause,  a  portion  of all of the  Participant's  outstanding  Awards  shall  be
immediately forfeited to the extent not then otherwise vested. The portion of an
Award  forfeited  shall be a  fraction,  the  denominator  of which is the total
number of months of any Restricted Period applicable to the Award (rounded up to
the  nearest  whole  month) and the  numerator  of which is the number of months
remaining in such  Restricted  Period (rounded up to the nearest whole month) as
of the termination of employment.


Options and Stock  Appreciation  Rights which are or become  exercisable  at the
time of a Participant's termination of employment with the Company (i) by reason
of  Disability  or Retirement or by the Company for any reason other than Cause,
may  be  exercised  by  the  Participant   within  three  years  following  such
termination of employment  and (ii) for any reason other than Cause,  death or a
reason specified in (i), may be exercised by the Participant within three months
following such termination but, in either event, not after the expiration of the
period  of  the  Option  and  Stock  Appreciation   Right.   Options  and  Stock
Appreciation   Rights  which  are  or  become  exercisable  at  the  time  of  a
Participant's termination of employment with the Company by reason of death, may
be exercised by the Participant's  designated beneficiary,  or in the absence of
such designation, by the person to whom the Participant's rights pass by will or
the laws of descent and  distribution  at any time within  three years after the
Participant's death but not after the expiration of the period of the Option and
Stock  Appreciation  Right.  Options and Stock  Appreciation  Rights that do not
become exercisable as provided above, or that are not otherwise vested, shall be
forfeited on termination.

In the event of a  Participant's  termination of employment with the Company for
any reason  other than as provided  above,  all Awards not  otherwise  vested or
earned as of the date of such  termination  of employment  shall be  immediately
forfeited on termination.

Notwithstanding  the  foregoing  however,   the  Committee  may  determine  that
termination of employment by reasons of any other special  circumstances not set
forth above shall not terminate an Award or a portion thereof.

XII.  AWARD AGREEMENT

Each person granted an Award pursuant to the Plan shall sign an Award  Agreement
which  signifies the offer of the Award by the Company and the acceptance of the
Award by the person in accordance with the terms of the Award and the provisions
of the Plan.  Each Award Agreement shall reflect the terms and conditions of the
Award.

XIII.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

In the  event of a change  in the  capitalization  of PEC due to a stock  split,
stock dividend, recapitalization, merger, consolidation, combination, or similar
event,  the aggregate  shares  subject to the Plan and the terms of any existing
Awards shall be adjusted by the Committee to reflect such change.

XV.   SECURITIES LAW AGREEMENT

If, at the time of the  exercise of any Option and Stock  Appreciation  Right in
the opinion of counsel for the Company,  it is necessary or desirable,  in order
to comply with any then applicable  laws or regulations  relating to the sale of
securities,  for the individual  exercising the Option, agree to hold any shares
issued to the  individual  for  investment  and without  intention  to resell or
distribute  the same and for the  individual  to agree to dispose of such shares
only in compliance with such laws and regulations, the individual will, upon the
request of the Company,  execute and deliver to the Company a further  agreement
to such effect.

XVI.  WITHHOLDING FOR TAXES

Any cash payment  under the Plan shall be reduced by any amounts  required to be
withheld or paid with respect thereto under all present or future federal, state
and local taxes and other laws and  regulations  that may be in effect as of the
date of each such payment ("Tax Amounts"). Any issuance of Common Stock pursuant
to the  exercise of an Option or other  distribution  of Common  Stock under the
Plan shall not be made  until  appropriate  arrangements  have been made for the
payment of any amounts  that may be required to be withheld or paid with respect
thereto.  Such  arrangements  may, at the discretion of the  Committee,  include
allowing the  Participant  to tender to the Company shares of Common Stock owned
by the Participant, being part of the broker-cash less exercise procedure; or to
request the  Company to  withhold a portion of the shares of Common  Stock being
acquired  pursuant to the exercise or otherwise  distributed to the Participant,
which have a Fair Market Value per share as of the date of such Award  exercise,
tender  or  withholding  that is not  greater  than the sum of all Tax  Amounts,
together with payment of any remaining  portion of all Tax Amounts in cash or by
check payable and acceptable to the Company.

          which the Director Option is being  exercised,  accompanied by payment
          in full of the option  purchase  price for such shares,  which payment
          may be (i) in cash by check  acceptable  to the  Company,  (ii) by the
          transfer to the Company of shares of Common Stock already owned by the
          optionee having an aggregate Fair Market Value at the date of exercise
          equal to the aggregate option purchase price,  (iii) from the proceeds
          of a sale  through a broker of some or all of the shares to which such
          exercise relates, or (iv) by a combination of such methods of payment.



     (e)  Each  Director  Option  shall  expire  10 years  from the  Grant  Date
          thereof,  but shall be subject to earlier termination as follows:  (1)
          to the extent exercisable as of the date a Director ceases to serve as
          a director of the  Company  (the  "Resignation  Date"),  the  Director
          Option may be exercised  only within  three years of such  Resignation
          Date by the optionee or the  optionee's  legal  representative  or the
          person to whom the Nonemployee Director's rights shall pass by will or
          the laws of descent and  distribution,  as the case may be, and to the
          extent not so exercised  shall  terminate on the third  anniversary of
          the  Resignation  Date and (2) to the extent not exercisable as of the
          Resignation   Date,  the  Director  Option  shall  terminate  on  such
          Resignation Date.

In the event that the number of shares of Common  Stock  available  for Director
Awards under this Plan is insufficient to make all automatic Awards provided for
in this Section XVII on the applicable date, then all Directors who are entitled
to a grant on such date  shall  share  ratably  in the  number  of  shares  then
available  for grant  under this Plan and shall have no right to receive a grant
with  respect  to the  deficiencies  in the number of  available  shares and all
future grants under this Section XVII shall terminate.

Grants made  pursuant to this  Section XVII shall be subject to all of the terms
and conditions of this Plan;  however,  if there is a conflict between the terms
and  conditions  of this Section XVII and the terms and  conditions of any other
Section,  then the terms and conditions of this Section XVII shall control.  The
Committee  may not  exercise  any  discretion  with respect to this Section XVII
which would be inconsistent with the intent that this Plan meet the requirements
of Rule 16b-3.

XVIII.  DESIGNATION OF BENEFICIARY

Each  Participant to whom an Award has been made under this Plan may designate a
beneficiary or  beneficiaries  (which  beneficiary may be an entity other than a
natural  person) to exercise  any rights or receive  any payment  that under the
terms  of  such  Award  may  become  exercisable  or  payable  on or  after  the
Participant's  death.  At any time, and from time to time, any such  designation
may be changed or  canceled by the  Participant  without the consent of any such
beneficiary.  Any such  designation,  change or  cancellation  must be on a form
provided for that  purpose by the  Committee  and shall not be  effective  until
received  by the  Committee.  If no  beneficiary  has been  named by a  deceased
Participant,  or the designated  beneficiaries have predeceased the Participant,
the beneficiary shall be the Participant's  estate. If a Participant  designates
more than one beneficiary, any such exercise or payment under this Plan shall be
made in equal shares unless the Participant has designated  otherwise,  in which
case the  exercise  or  payment  shall be made in the shares  designated  by the
Participant.


XIX.  PREEMPTION BY APPLICABLE LAWS AND REGULATIONS

Anything in the Plan or any  agreement  entered into pursuant to the Plan to the
contrary  notwithstanding,  if, at any time specified  herein or therein for the
making of any  determination,  the issuance or other  distribution  of shares of
Common  Stock,  the payment of  consideration  to an employee as a result of the
exercise of any Stock Appreciation  Right, any law, regulation or requirement of
any  governmental  authority  having  jurisdiction in the premises shall require
either the Company or the Participant (or the Participant's beneficiary), as the
case may be, to take any action in connection with any such  determination,  the
shares  then  to be  issued  or  distributed,  or such  payment,  the  issue  or
distribution of such shares or the making of such  determination or payment,  as
the case may be, shall be deferred until such action shall have been taken.

XX.  EFFECTIVE DATE AND DURATION OF PLAN

This Plan amendment and  restatement  shall become  effective as of February 25,
2000  subject to its  approval by the  stockholders  of PEC.  Unless  previously
terminated by the Board,  the Plan shall  terminate on the tenth  anniversary of
its approval by the stockholders; provided, however, that such termination shall
not  terminate any Award then  outstanding.  No Awards shall be made pursuant to
this Plan after December 31, 2005.

 XXI.  TERMINATION AND AMENDMENT

The Board may suspend,  terminate,  modify or amend the Plan,  provided that any
amendment that would increase the aggregate number of shares which may be issued
under the Plan or  materially  modify the  requirements  as to  eligibility  for
participation   in  the  Plan,  shall  be  subject  to  the  approval  of  PEC's
stockholders, except that any such increase or modification that may result from
adjustments authorized by Section XIII does not require such approval; provided,
further,  that no amendment or  modification  shall be made to Section XVII more
than once every six months,  other than to comport  with  changes in the Code or
the  Employee  Retirement  Income  Security  Act of 1974,  as amended,  or rules
promulgated thereunder. No suspension, termination, modification or amendment of
the Plan may terminate a  Participant's  existing Award or materially  adversely
affect a Participant's rights under such Award.

XXII.  MISCELLANEOUS

(a)  Nothing  contained in the Plan shall be construed  as  conferring  upon any
     employee the right to continue in the employ of the Company.

(b)  No person  shall have any rights as a  stockholder  with  respect to shares
     covered by such person's  Option,  until the date of the issuance of shares
     pursuant  thereto.  No  adjustment  will be made  for  dividends  or  other
     distributions  or rights for which the record  date is prior to the date of
     such issuance.

(c)  Nothing contained in the Plan shall be construed as giving any person, such
     person's  beneficiaries or any other person any equity or other interest of
     any kind in any assets of the  Company or creating a trust of any kind or a
     fiduciary relationship of any kind between the Company and any such person.



(d)  Nothing  contained  in the Plan shall be  construed  to prevent the Company
     from  taking  any  corporate  action  that is deemed by the  Company  to be
     appropriate or in its best interest,  whether or not such action would have
     an  adverse  effect  on the Plan or any  award  made  under  the  Plan.  No
     employee,  beneficiary  or other  person  shall have any claim  against the
     Company as a result of any such action.

(e)  No grantee  nor any  beneficiary  thereof  shall have the power or right to
     sell, exchange,  pledge, transfer,  assign or otherwise encumber or dispose
     of any such grantee's or  beneficiary's  interest arising under the Plan or
     in any Award received under the Plan; nor shall such interest be subject to
     seizure for the payment of any grantee's or beneficiary's debts, judgments,
     alimony, or separate  maintenance or be transferable by operation of law in
     the event of a grantee's or  beneficiary's  bankruptcy or insolvency and to
     the extent any such interest arising under the Plan or Award received under
     the Plan is awarded to a spouse  pursuant to any divorce  proceeding,  such
     interest shall be deemed to be terminated and forfeited notwithstanding any
     vesting  provisions  or other terms herein or in the  agreement  evidencing
     such award.

(f)  All rights and  obligations  under the Plan shall be  governed  by, and the
     Plan  shall be  construed  in  accordance  with,  the laws of the  State of
     Oklahoma without regard to the principles of conflicts of laws.  Titles and
     headings to Sections  herein are for purposes of reference  only, and shall
     in no way limit,  define or otherwise affect the meaning or  interpretation
     of any provisions of the Plan.
