                          EL PASO NATURAL GAS COMPANY
                     OMNIBUS PLAN FOR MANAGEMENT EMPLOYEES
              AMENDED AND RESTATED EFFECTIVE AS OF APRIL 12, 1996


                             SECTION 1     PURPOSE

         The purpose of the El Paso Natural Gas Company Omnibus Plan for
Management Employees, formerly known as the El Paso Natural Gas Company Stock
Option Plan for Management Employees, (the "Plan") is to promote the interests
of El Paso Natural Gas Company (the "Company") and its stockholders by
strengthening its ability to attract and retain key employees in the employ of
the Company and its Subsidiaries (as defined below) by furnishing suitable
recognition of their ability and industry which materially contributes to the
success of the Company.  The Plan provides for the grant of stock options,
limited stock appreciation rights, stock appreciation rights and restricted
stock in accordance with the terms and conditions set forth below.


                           SECTION 2     DEFINITIONS

         Unless otherwise required by the context, the following terms when
used in the Plan shall have the meanings set forth in this Section 2:

2.1      BENEFICIARY

         The person or persons designated by the Participant pursuant to
Section 6.2(f) to whom payments are to be paid pursuant to the terms of the
Plan in the event of the Participant's death.

2.2      BOARD OF DIRECTORS

         The Board of Directors of the Company.

2.3      CAUSE

         A termination for Cause is a termination evidenced by a statement
adopted in good faith by the Management Committee that the Participant (i)
willfully and continually failed to substantially perform the Participant's
duties with the Company (other than a failure resulting from the Participant's
incapacity due to physical or mental illness) which failure continued for a
period of at least thirty (30) days after a written notice of demand for
substantial performance has been delivered to the Participant specifying the
manner in which the Participant has failed to substantially perform or (ii)
willfully engaged in conduct which is demonstrably and materially injurious to
the Company, monetarily or otherwise; provided, however, that no termination of
the Participant's employment shall be for Cause as set forth in clause (ii)
above until (A) there shall have been delivered to the Participant a

   4
copy of a written notice setting forth that the Participant was guilty of the
conduct set forth in clause (ii) above and specifying the particulars thereof
in detail, and (B) the Participant shall have been provided an opportunity to
be heard by the Management Committee (with the assistance of the Participant's
counsel if the Participant so desires).  No act, nor failure to act, on the
Participant's part shall be considered "willful" unless the Participant has
acted, or failed to act, with an absence of good faith and without a reasonable
belief that the Participant's action or failure to act was in the best interest
of the Company.  Notwithstanding anything contained in the Plan to the
contrary, no failure to perform by the Participant after notice of termination
is given to the Participant shall constitute Cause.

2.4      CHANGE IN CONTROL

         As used in the Plan, a Change in Control shall be deemed to occur (i)
if any person (as such term is used in Sections 13(d) and 14(d)(2) of the
Exchange Act) is or becomes the "beneficial owner" (as defined in Rule 13d-3 of
the Exchange Act), directly or indirectly, of securities of the Company
representing twenty percent (20%) or more of the combined voting power of the
Company's then outstanding securities, (ii) upon the first purchase of the
Common Stock pursuant to a tender or exchange offer (other than a tender or
exchange offer made by the Company), (iii) upon the approval by the Company's
stockholders of a merger or consolidation, a sale or disposition of all or
substantially all the Company's assets or a plan of liquidation or dissolution
of the Company, or (iv) if, during any period of two (2) consecutive years,
individuals who at the beginning of such period constitute the Board of
Directors cease for any reason to constitute at least a majority thereof,
unless the election or nomination for the election by the Company's
stockholders of each new director was approved by a vote of at least two-thirds
(2/3) of the directors then still in office who were directors at the beginning
of the period. Notwithstanding the foregoing, a Change in Control shall not be
deemed to occur if the Company either merges or consolidates with or into
another company or sells or disposes of all or substantially all of its assets
to another company, if such merger, consolidation, sale or disposition is in
connection with a corporate restructuring wherein the stockholders of the
Company immediately before such merger, consolidation, sale or disposition own,
directly or indirectly, immediately following such merger, consolidation, sale
or disposition at least eighty percent (80%) of the combined voting power of
all outstanding classes of securities of the company resulting from such merger
or consolidation, or to which the Company sells or disposes of its assets, in
substantially the same proportion as their ownership in the Company immediately
before such merger, consolidation, sale or disposition.

2.5      CODE

         The Internal Revenue Code of 1986, as amended and in effect from time
to time, and the temporary or final regulations of the Secretary of the U.S.
Treasury adopted pursuant to the Code.

2.6      COMMON STOCK

         The common stock of the Company, $3 par value per share, or such other
class of shares or other securities as may be applicable pursuant to the
provisions of Section 5.

2.7      EXCHANGE ACT

         The Securities Exchange Act of 1934, as amended.

2.8      FAIR MARKET VALUE

         As applied to a specific date, Fair Market Value shall be deemed to be
the mean between the highest and lowest quoted selling prices at which Common
Stock was sold on such date as reported in the NYSE-Composite Transactions by
The Wall Street Journal on such date, or if no Common Stock was traded on such
date, on the next preceding day on which Common Stock was so traded.

         Notwithstanding the foregoing, upon the exercise,

              (a)         during the thirty (30) day period following a Change
         in Control, of a limited stock appreciation right or stock
         appreciation right granted in connection with an Option more than six
         (6) months prior to a Change in Control, or

              (b)         during the seven (7) month period following a Change
         in Control, of a limited stock appreciation right or of a stock
         appreciation right granted in connection with an Option less than six
         (6) months prior to a Change in Control,

         On or after a Change in Control, Fair Market Value on the date of
         exercise shall be deemed to be the greater of (i) the highest price
         per share of Common Stock as reported in the NYSE-Composite
         Transactions by The Wall Street Journal during the sixty (60) day
         period ending on the day preceding the date of exercise of the stock
         appreciation right or limited stock appreciation right, as the case
         may be, and (ii) if the Change in Control is one described in clause
         (ii) or (iii) of Section 2.4, the highest price per share paid for
         Common Stock in connection with such Change in Control.

2.9      GOOD REASON

         Good Reason shall mean the occurrence of any of the following events
or conditions, after a Change in Control:

              (a)         a change in the Participant's status, title, position
         or responsibilities (including reporting responsibilities) which, in
         the Participant's reasonable judgment, represents a substantial
         reduction of the status, title, position or responsibilities as in
         effect immediately prior thereto; the assignment to the

         Participant of any duties or responsibilities which, in the
         Participant's reasonable judgment, are inconsistent with such status,
         title, position or responsibilities; or any removal of the Participant
         from or failure to reappoint or reelect the Participant to any of such
         positions, except in connection with the termination of the
         Participant's employment for Cause, for Permanent Disability, as a
         result of his or her death, or by the Participant other than for Good
         Reason;

              (b)         a reduction in the Participant's annual base salary;

              (c)         the Company requires the Participant (without the
         consent of the Participant) to be based at any place outside a
         thirty-five (35) mile radius of his or her place of employment prior
         to a Change in Control, except for reasonably required travel due to
         the Company's business which is not materially greater than such
         travel requirements prior to the Change in Control;

              (d)         the failure by the Company to (i) continue in effect
         any material compensation or benefit plan in which the Participant was
         participating at the time of the Change in Control, including, but not
         limited to, the Plan, the El Paso Natural Gas Company Pension Plan and
         the El Paso Natural Gas Company Retirement Savings Plan; or (ii)
         provide the Participant with compensation and benefits at least equal
         (in terms of benefit levels and/or reward opportunities) to those
         provided for under each employee benefit plan, program and practice as
         in effect immediately prior to the Change in Control (or as in effect
         following the Change in Control, if greater);

              (e)         any material breach by the Company of any provision 
         of the Plan; or

              (f)         any purported termination of the Participant's
         employment for Cause by the Company which does not otherwise comply
         with the terms of the Plan.

exercisable.

association that is treated as a corporation for tax purposes) of which shares
(or other ownership interests) having more than fifty percent (50%) of the
voting power are owned or controlled, directly or indirectly, by the Company so
as to qualify as a "subsidiary corporation" within the meaning of Section

interpret the Plan, to establish, amend and rescind rules and regulations
relating to the Plan, to select persons eligible to participate in the Plan, to
grant Options, limited stock appreciation rights, stock appreciation rights and

upon all Participants.  The Plan Administrator shall cause the Company at its
expense to take any action related to the Plan which may be required or
necessary to comply with the provisions of any federal or state law or any
regulations issued thereunder.

         3.4     Each member of the Management Committee acting as Plan
Administrator, while serving as such, shall be considered to be acting in his
or her capacity as an officer of the Company.  Members of the Management
Committee acting under the Plan shall be fully protected in relying in good
faith upon the advice of counsel and shall incur no liability except for gross
negligence or willful misconduct in the performance of their duties.


                           SECTION 4     ELIGIBILITY

         To be eligible for selection by the Plan Administrator to participate

(ii) the surrender of an Option, or portion thereof, upon exercise of a related
limited stock appreciation right or stock appreciation right for cash, or (iii)

         5.2     In the event of a recapitalization, stock split, stock
dividend, exchange of shares, merger, reorganization, change in corporate
structure or shares of the Company or similar event, the Board of Directors,
upon the recommendation of the Plan Administrator, may make appropriate
adjustments in the number of shares authorized for the Plan and, with respect
to outstanding Options, limited stock appreciation rights, stock appreciation
rights and Restricted Stock, the Plan Administrator may make appropriate
adjustments in the number of shares and the Option Price.


                          SECTION 6     STOCK OPTIONS

         6.1     Options may be granted to eligible employees in such number
and at such times during the term of the Plan as the Plan Administrator shall
determine. When determining a grant, the Plan Administrator may take into
account the duties of the respective employees, their present and potential
contributions to the success of the Company, and such other factors as the Plan
Administrator shall deem relevant in accomplishing the purpose of the Plan.
The granting of an Option shall take place when the Plan Administrator
determines to grant such an Option to a particular Participant at the Option
Price.  Each Option shall be evidenced by a written instrument delivered by or
on behalf of the Company containing provisions not inconsistent with the Plan.

         6.2     All Options under the Plan shall be granted subject to the
following terms and conditions:

         (A)     OPTION PRICE

                 The Option Price shall be the Fair Market Value of the Common
         Stock on the date the Option is granted, unless otherwise specified by
         the Plan Administrator.

         (B)     DURATION OF OPTIONS

                 Options shall be exercisable at such time and under such
         conditions as set forth in the Option grant, but in no event shall any
         Option be exercisable later than the tenth anniversary of the date of
         its grant.

         (C)     EXERCISE OF OPTIONS

                 Subject to Section 6.2(j), a Participant may not exercise an
         Option until the Participant has completed one (1) year of continuous
         employment with the Company or any of its Subsidiaries immediately
         following the date on which the Option is granted, or such other
         shorter or longer period as the Plan Administrator may determine in a
         particular case.  This requirement is waived in the event of death or
         Permanent Disability of a Participant before such period of continuous





- --------------------------------------------------------------------------------

   10
         employment is completed and may be waived or modified in the agreement
         evidencing the Option or by written notice to the Participant from the
         Plan Administrator.  Thereafter, shares of Common Stock covered by an
         Option may be purchased at one time or in such installments over the
         balance of the Option period as may be provided in the Option grant.
         Any shares not purchased on the applicable installment date may be
         purchased at one time or in such installments at any time prior to the
         final expiration of the Option as may be provided in the Option grant.
         To the extent that the right to purchase shares has accrued
         thereunder, Options may be exercised from time to time by providing
         written notice to the Company setting forth the number of shares to
         which the Option is being exercised.

         (D)     PAYMENT

                 The product of the Option Price and the number of shares
         purchased (the "Purchase Price") shall be paid in full to the Company
         upon the exercise of an Option.  The Purchase Price may be paid either
         (i) in cash or (ii) at the discretion of the Plan Administrator, in
         Common Stock already owned by the Participant for at least six (6)
         months, or any combination of cash and Common Stock.  The Fair Market
         Value of such Common Stock as delivered shall be valued as of the day
         prior to delivery.  To the extent permitted by the Plan Administrator
         and applicable laws and regulations (including, but not limited to,
         federal tax and securities laws and regulations and state corporate
         law), an Option may also be exercised by delivering a properly
         executed exercise notice together with irrevocable instructions to a
         broker to promptly deliver to the Company the amount of sale or loan
         proceeds to pay the Purchase Price.  A Participant shall have none of
         the rights of a stockholder until the shares of Common Stock are
         issued to the Participant.

         (E)     RESTRICTIONS

                 The Plan Administrator shall determine, with respect to each
         Option, the nature and extent of the restrictions, if any, to be
         imposed on the shares of Common Stock which may be purchased
         thereunder, including, but not limited to, restrictions on the
         transferability of such shares acquired through the exercise of an
         Option for such periods as the Plan Administrator may determine and,
         further, that in the event a Participant's employment by the Company,
         or a Subsidiary, terminates during the period in which such shares are
         nontransferable, the Participant shall be required to sell such shares
         back to the Company at such prices as the Plan Administrator may
         specify in the Option.

         (F)     NONTRANSFERABILITY OF OPTIONS

                 During a Participant's lifetime, an Option may be exercisable
         only by the Participant. Options granted under the Plan and the rights
         and privileges conferred





- --------------------------------------------------------------------------------

   11
         thereby shall not be subject to execution, attachment or similar
         process and may not be transferred, assigned, pledged or hypothecated
         in any manner (whether by operation of law or otherwise) other than by
         will or by the applicable laws of descent and distribution, except
         that to the extent permitted by applicable law, the Plan Administrator
         may permit a recipient of an Option to designate in writing during the
         Participant's lifetime a Beneficiary to receive and exercise Options
         in the event of such Participant's death (as provided in Section
         6.2(i)).  Any attempt to transfer, assign, pledge, hypothecate or
         otherwise dispose of any Option under the Plan or of any right or
         privilege conferred thereby, contrary to the provisions of the Plan,
         or the sale or levy or any attachment or similar process upon the
         rights and privileges conferred hereby, shall be null and void.

         (G)     PURCHASE FOR INVESTMENT

                 The Plan Administrator shall have the right to require that
         each Participant or other person who shall exercise an Option under
         the Plan, and each person into whose name shares of Common Stock shall
         be issued pursuant to the exercise of an Option, represent and agree
         that any and all shares of Common Stock purchased pursuant to such
         Option are being purchased for investment only and not with a view to
         the distribution or resale thereof and that such shares will not be
         sold except in accordance with such restrictions or limitations as may
         be set forth in the Option.  This Section 6.2(g) shall be inoperative
         during any period of time when the Company has obtained all necessary
         or advisable approvals from governmental agencies and has completed
         all necessary or advisable registrations or other qualifications of
         shares of Common Stock as to which Options may from time to time be
         granted.

         (H)     TERMINATION OF EMPLOYMENT

                 Upon the termination of a Participant's employment for any
         reason other than death or Permanent Disability, the Participant's
         Option shall be exercisable only to the extent that it was then
         exercisable and, unless the term of the Option expires sooner, such
         Option shall expire according to the following schedule; provided,
         that the Plan Administrator may at any time determine in a particular
         case that specific limitations and restrictions under the Plan shall
         not apply:

                 (I)      RETIREMENT

                          The Option shall expire, unless exercised, thirty-six
                 (36) months after the Participant's retirement from the
                 Company or any Subsidiary.

                 (II)     DISABILITY

                          The Option shall expire, unless exercised, thirty-six
                 (36) months after the Participant's Permanent Disability.

   12
                 (III)    TERMINATION

                          Subject to subparagraph (iv) below, the Option shall
                 expire, unless exercised, thirty-six (36) months after a
                 Participant resigns or is terminated as an employee of the
                 Company or any of its Subsidiaries, unless the Plan
                 Administrator shall have determined in a specific case that
                 the Option should expire sooner or should terminate when the
                 Participant's employment status ceases.

                 (IV)     TERMINATION FOLLOWING A CHANGE IN CONTROL

                          The Option shall expire, unless exercised, within
                 thirty-six (36) months of a Participant's termination of
                 employment (other than a termination by the Company for Cause
                 or a voluntary termination by the Participant other than for
                 Good Reason) following a Change in Control, provided that said
                 termination of employment occurs within two (2) years
                 following a Change in Control.

                 (V)      ALL OTHER TERMINATIONS

                          Except as provided in subparagraphs (iii) and (iv)
                 above, the Option shall expire upon termination of employment.

         (I)     DEATH OF PARTICIPANT

                 Upon the death of a Participant, whether during the
         Participant's period of employment or during the thirty-six (36) month
         period referred to in Sections 6.2(h)(i), (ii) and (iii), the Option
         shall expire, unless the term of the Option expires sooner, twelve
         (12) months after the date of the Participant's death, unless the
         Option is exercised within such twelve (12) month period by the
         Participant's Beneficiary, legal representatives, estate or the person
         or persons to whom the deceased's Option rights shall have passed by
         will or the laws of descent and distribution; provided, that the Plan
         Administrator may determine in a particular case that specific
         limitations and restrictions under the Plan shall not apply.

         (J)     CHANGE IN CONTROL

                 Notwithstanding other Plan provisions pertaining to the times
         at which Options may be exercised, all outstanding Options, to the
         extent not then currently exercisable, shall become exercisable in
         full upon the occurrence of a Change in Control.  No Option shall be
         exercisable at a time that would violate the maximum duration of
         Section 6.2(b).

                    SECTION 7     STOCK APPRECIATION RIGHTS

         7.1     The Plan Administrator may grant stock appreciation rights to
Participants in connection with any Option granted under the Plan, either at
the time of the grant of such Option or at any time thereafter during the term
of the Option.  Such stock appreciation rights shall cover the same shares
covered by the Options (or such lesser number of shares of Common Stock as the
Plan Administrator may determine) and shall, except as provided in Section 7.3,
be subject to the same terms and conditions as the related Options and such
further terms and conditions not inconsistent with the Plan as shall from time
to time be determined by the Plan Administrator.

         7.2     Each stock appreciation right shall entitle the holder of the
related Option to surrender to the Company the related unexercised Option, or
any portion thereof, and to receive from the Company in exchange therefor an
amount equal to the excess of the Fair Market Value of one share of Common
Stock on the date the right is exercised over the Option Price per share times
the number of shares covered by the Option, or portion thereof, which is
surrendered.  Payment shall be made in shares of Common Stock valued at Fair
Market Value as of the date the right is exercised, or in cash, or partly in
shares and partly in cash, at the discretion of the Plan Administrator;
provided, however, that payment shall be made solely in cash with respect to a
stock appreciation right which is exercised within seven (7) months following a
Change in Control.  Stock appreciation rights may be exercised from time to
time upon actual receipt by the Company of written notice stating the number of
shares of Common Stock with respect to which the stock appreciation rights are
being exercised.  The value of any fractional shares shall be paid in cash.

         7.3     Stock appreciation rights are subject to the following
restrictions:

              (a)         Each stock appreciation right shall be exercisable at
         such time or times that the Option to which they relate shall be
         exercisable or at such other times as the Plan Administrator may
         determine; provided, however, that such rights shall not be
         exercisable until the Participant shall have completed six (6) months
         of continuous employment with the Company or any of its Subsidiaries
         immediately following the date on which the stock appreciation right
         is granted. In the event of death or Permanent Disability of a
         Participant during employment but before the Participant has completed
         such period of continuous employment, such stock appreciation right
         shall be exercisable only within the period specified in the related
         Option.  In the event of a Change in Control, the requirement that a
         Participant shall have completed a six (6) month period of continuous
         employment is waived with respect to a Participant who is employed by
         the Company at the time of the Change in Control but who, within the
         six (6) month period, voluntarily terminates employment for Good
         Reason or is terminated by the Company other than for Cause.

   14
              (b)         Except in the event of a Change in Control, the Plan
         Administrator in its sole discretion may approve or deny in whole or
         in part a request to exercise a stock appreciation right.  Denial or
         approval of such request shall not require a subsequent request to be
         similarly treated by the Plan Administrator.

              (c)         The right of a Participant to exercise a stock
         appreciation right shall be canceled if and to the extent the related
         Option is exercised.  To the extent that a stock appreciation right is
         exercised, the related Option shall be deemed to have been
         surrendered, unexercised and canceled.

              (d)         A holder of stock appreciation rights shall have none
         of the rights of a stockholder until shares of Common Stock, if any,
         are issued to such holder pursuant to such holder's exercise of such
         rights.

              (e)         The acquisition of Common Stock pursuant to the
         exercise of a stock appreciation right shall be subject to the same
         restrictions as would apply to the acquisition of Common Stock
         acquired upon acquisition of the related Option, as set forth in
         Section 6.2.


SECTION 8     LIMITED STOCK APPRECIATION RIGHTS

         8.1     The Plan Administrator may grant limited stock appreciation
rights to Participants in connection with any Options granted under the Plan,
either at the time of the grant of such Option or at any time thereafter during
the term of the Option.  Such limited stock appreciation rights shall cover the
same shares covered by the Options (or such lesser number of shares of Common
Stock as the Plan Administrator may determine) and shall, except as provided in
Section 8.3, be subject to the same terms and conditions as the related Options
and such further terms and conditions not inconsistent with the Plan as shall
from time to time be determined by the Plan Administrator.

         8.2     Each limited stock appreciation right shall entitle the holder
of the related Option to surrender to the Company the unexercised portion of
the related Option and to receive from the Company in exchange therefor an
amount in cash equal to the excess of the Fair Market Value of one (1) share of
Common Stock on the date the right is exercised over the Option Price per share
times the number of shares covered by the Option, or portion thereof, which is
surrendered.

         8.3     Limited stock appreciation rights are subject to the following
restrictions:

              (a)         Each limited stock appreciation right shall be
         exercisable in full for a period of seven (7) months following the
         date of a Change in Control, provided, however, that limited stock
         appreciation rights may not be exercised under any circumstances until
         the expiration of the six (6) month period following the date of
         grant.  Limited stock appreciation rights shall be exercisable only to
         the same

         extent and subject to the same conditions as the Options related
         thereto are exercisable, as provided in Section 6.2(j).

              (b)         The right of a Participant to exercise a limited
         stock appreciation right shall be canceled if and to the extent the
         related Option is exercised. To the extent that a limited stock
         appreciation right is exercised, the related Option shall be deemed to
         have been surrendered, unexercised and canceled.


                         SECTION 9     RESTRICTED STOCK

         9.1     Restricted Stock may be granted to Participants in such number
and at such times during the term of the Plan as the Plan Administrator shall
determine, the Plan Administrator taking into account the duties of the
respective Participants, their present and potential contributions to the
success of the Company, and such other factors as the Plan Administrator shall
deem relevant in accomplishing the purposes of the Plan.  The granting of
Restricted Stock shall take place when the Plan Administrator by resolution,
written consent or other appropriate action determines to grant such Restricted
Stock to a particular Participant.  Each grant shall be evidenced by a written
instrument delivered by or on behalf of the Company containing provisions not
inconsistent with the Plan.  The Participant receiving a grant of Restricted
Stock shall be recorded as a stockholder of the Company.  Each Participant who
receives a grant of Restricted Stock shall have all the rights of a stockholder
with respect to such shares (except as provided in the restrictions on
transferability), including the right to vote the shares and receive dividends
and other distributions; provided, however, that no Participant awarded
Restricted Stock shall have any right as a stockholder with respect to any
shares subject to the Participant's Restricted Stock grant prior to the date of
issuance to the Participant of a certificate or certificates for such shares.

         9.2     A grant of Restricted Stock shall entitle a Participant to
receive, on the date or dates designated by the Plan Administrator, upon
payment to the Company of the par value of the Common Stock in a manner
determined by the Plan Administrator, the number of shares of Common Stock
selected by the Plan Administrator.  The Plan Administrator may require, under
such terms and conditions as it deems appropriate or desirable, that the
certificates for Restricted Stock delivered under the Plan may be held in
custody by a bank or other institution, or that the Company may itself hold
such shares in custody until the Restriction Period (as defined in Section 9.3)
expires or until restrictions thereon otherwise lapse, and may require, as a
condition of any issuance of Restricted Stock that the Participant shall have
delivered a stock power endorsed in blank relating to the shares of Restricted
Stock.

         9.3     During a period of years following the date of grant, which
shall in no event be less than one (1) year and until required performance
targets are achieved, if applicable, as determined by the Plan Administrator
(the "Restriction Period"), the Restricted Stock may not be sold, assigned,
transferred, pledged, hypothecated or





- --------------------------------------------------------------------------------

otherwise encumbered or disposed of by the recipient, except in the event of
death or Permanent Disability, the transfer to the Company as provided under
the Plan or the Plan Administrator's waiver or modification of such
restrictions in the agreement evidencing the grant of Restricted Stock, or by
resolution of the Plan Administrator adopted at any time.

         9.4     Except as provided in Section 9.5 or 9.6, if a Participant
terminates employment with the Company for any reason before the expiration of
the Restriction Period, all shares of Restricted Stock still subject to
restriction shall be forfeited by the Participant to the Company.  In addition,
in the event of any attempt by the Participant to sell, exchange, transfer,
pledge or otherwise dispose of shares of Restricted Stock in violation of the
terms of the Plan, such shares shall be forfeited to the Company.

         9.5     The Restriction Period for any Participant shall be deemed to
end and all restrictions on shares of Restricted Stock shall lapse, upon the
Participant's death, Permanent Disability, retirement or any termination of
employment determined by the Plan Administrator to end the Restriction Period.

         9.6     The Restriction Period for any Participant shall be deemed to
end and all restrictions on shares of Restricted Stock shall terminate
immediately upon a Change in Control.

         9.7     When the restrictions imposed by Section 9.3 expire or
otherwise lapse with respect to one or more shares of Restricted Stock, the
Company shall deliver to the Participant (or the Participant's legal
representative, Beneficiary or heir) one (1) share of Common Stock for each
share of Restricted Stock.  At that time, the agreement referred to in Section
9.1, as it relates to such shares, shall be terminated.

         9.8     Subject to Section 9.2, a Participant entitled to receive
Restricted Stock under the Plan shall be issued a certificate for such shares.
Such certificate shall be registered in the name of the Participant, and shall
bear an appropriate legend reciting the terms, conditions and restrictions, if
any, applicable to such shares and shall be subject to appropriate
stop-transfer orders.


                SECTION 10     REGULATORY APPROVALS AND LISTING

         10.1    The Company shall not be required to issue any certificate for
shares of Common Stock upon the exercise of an Option or a stock appreciation
right granted under the Plan, or with respect to a grant of Restricted Stock
prior to:

              (a)         the obtaining of any approval or ruling from the
         Securities and Exchange Commission, the Internal Revenue Service or
         any other governmental agency which the Company, in its sole
         discretion, shall determine to be necessary or advisable;

              (b)         the listing of such shares on any stock exchange on
         which the Common Stock may then be listed; or

              (c)         the completion of any registration or other
         qualification of such shares under any federal or state laws, rulings
         or regulations of any governmental body which the Company, in its sole
         discretion, shall determine to be necessary or advisable.


               SECTION 11     EFFECTIVE DATE AND TERM OF THE PLAN

         The Plan was originally adopted by the Board of Directors as of
December 14, 1993, and was amended and restated by the Board of Directors
effective April 12, 1996.  Options, limited stock appreciation rights, stock
appreciation rights and Restricted Stock may be granted pursuant to the Plan
from time to time as the Plan Administrator shall determine.  The Plan shall
terminate on December 14, 2003.  However, Options, limited stock appreciation
rights, stock appreciation rights and Restricted Stock granted prior to the
expiration of the Plan may extend beyond that date and the terms and conditions
of the Plan shall continue to apply thereto and to shares of Common Stock
acquired hereunder.


                       SECTION 12     GENERAL PROVISIONS

         12.1    Nothing contained in the Plan, or in any Option, limited stock
appreciation right, stock appreciation right or Restricted Stock granted
pursuant to the Plan, shall confer upon any employee any right with respect to
continuance of employment by the Company or a Subsidiary, nor interfere in any
way with the right of the Company or a Subsidiary to terminate the employment
of such employee at any time with or without assigning any reason therefor.

         12.2    Grants, vesting or payment of Options, limited stock
appreciation rights, stock appreciation rights or Restricted Stock shall not be
considered as part of a Participant's salary or used for the calculation of any
other pay, allowance, pension or other benefit unless otherwise permitted by
other benefit plans provided by the Company or its Subsidiaries, or required by
law or by contractual obligations of the Company or its Subsidiaries.

         12.3    The right of a Participant or Beneficiary to the payment of
any compensation under the Plan may not be assigned, transferred, pledged or
encumbered, nor shall such right or other interests be subject to attachment,
garnishment, execution or other legal process.

         12.4    Leaves of absence for such periods and purposes conforming to
the personnel policy of the Company, or of its Subsidiaries, as applicable,
shall not be deemed terminations or interruptions of employment.

         12.5    In the event a Participant is transferred from the Company to
a Subsidiary, or vice versa, or is promoted or given different
responsibilities, the Options, limited stock appreciation rights, stock
appreciation rights and Restricted Stock granted to the Participant prior to
such date shall not be affected.  Notwithstanding the foregoing or any other
provision in this Plan, in the event a Participant becomes an officer or
director of the Company subject to Section 16(b) of the Exchange Act, the Plan
Administrator may take any and all action necessary to prevent any violation of
Section 16(b), including, but not limited to, accelerating the vesting of
Options, rights or Restricted Stock, canceling any unvested Options, rights or
Restricted Stock and/or requiring the Participant to exercise any and all
vested Options or rights at such times as the Plan Administrator may determine.

         12.6    Each grant to a Participant of an Option, limited stock
appreciation right, stock appreciation right and Restricted Stock hereunder
shall make reference to this Plan by title and date to confirm the
applicability of the Plan and the source of shares and rights covered by the
grant.

         12.7    The Plan shall be construed and governed in accordance with
the laws of the State of Texas, except that it shall be construed and governed
in accordance with applicable federal law in the event that such federal law
preempts state law.

         12.8    Appropriate provision shall be made for all taxes required to
be withheld in connection with the exercise, grant or other taxable event with
respect to Options, limited stock appreciation rights, stock appreciation
rights and Restricted Stock under the applicable laws or regulations of any
governmental authority, whether federal, state or local and whether domestic or
foreign.  Unless otherwise provided in the grant, a Participant is permitted to
deliver shares of Common Stock for payment of withholding taxes on the exercise
of an option, stock appreciation right, or limited stock appreciation right or
upon the grant or vesting of Restricted Stock.  At the election of the Plan
Administrator or, subject to approval of the Plan Administrator at its sole
discretion, at the election of a Participant, shares of Common Stock may be
withheld from the shares issuable to the Participant upon the exercise of an
option or stock appreciation right or upon the vesting of the Restricted Stock
to satisfy tax withholding obligations.  The Fair Market Value of Common Stock
as delivered pursuant to this Section 12.8 shall be valued as of the day prior
to delivery, and shall be calculated in accordance with Section 2.8.

      SECTION 13     AMENDMENT, TERMINATION OR DISCONTINUANCE OF THE PLAN

         13.1    Subject to Section 13.2, the Plan Administrator may from time
to time make such amendments to the Plan as it may deem proper and in the best
interest of the Company without further approval of the Board of Directors,
including, but not limited to, any amendment necessary to ensure that the
Company may obtain any regulatory approval referred to in Section 10; provided,
however, that no change in any Option, limited stock appreciation right, stock
appreciation right or Restricted Stock theretofore granted may be made without
the consent of the Participant which would impair the right of the Participant
to acquire or retain Common Stock or cash that the Participant may have
acquired as a result of the Plan.

         13.2    The Plan Administrator may not amend the Plan without the
approval of the Board of Directors to:

              (a)         increase the number of shares or rights that may be
         issued under the Plan; or

              (b)         otherwise materially increase the benefits accruing
         to the Participants under the Plan.

         13.3    The Plan Administrator may at any time suspend the operation
of or terminate the Plan with respect to any shares of Common Stock not subject
to Option, limited stock appreciation right, stock appreciation right or
Restricted Stock at the time.
