ITEM 4.  DESCRIPTION OF SECURITIES

     Not applicable.


ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

     The validity of the Common Stock registered pursuant hereto has been passed
upon by Linda S. Peterson, a Senior Counsel of the Registrant. Ms. Peterson
beneficially owns, and has rights to acquire under employee stock options, an
aggregate of less than 1% of the outstanding shares of Common Stock of
Occidental.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers under certain circumstances for liabilities incurred in connection
with their activities in such capacities (including reimbursement for expenses
incurred). Occidental's Restated Certificate of Incorporation, as amended,
provides for the elimination of personal liability of its directors to the full
extent permitted by the Delaware General Corporation Law and Occidental has
entered into indemnification agreements with each director and certain officers
providing for additional indemnification. Article VIII of Occidental's By-laws
provides that Occidental shall indemnify directors and officers under certain
circumstances for liabilities and expenses incurred by reason of their
activities in such capacities. In addition, Occidental has insurance policies
that provide liability coverage to directors and officers while acting in such
capacities.

ITEM 9.  UNDERTAKINGS

     The undersigned Registrant hereby undertakes:

          1.   To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

               (i)       To include any prospectus required by Section 10(a)(3)
of the Securities Act of 1933;

               (ii)      To reflect in the prospectus any facts or events
arising after the effective date of the registration statement (or the most
recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
registration statement. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or
high end of the estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than 20% change in
the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement.

               (iii)     To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement.

          2.   That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          3.   To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing

                                       4
<PAGE>

provisions, or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

                                       5

                                POWER OF ATTORNEY

         Re:      Occidental Petroleum Corporation
                  Registration Statement on Form S-8
                  Occidental Petroleum Corporation Savings Plan

Ladies and Gentlemen:

     I am a Senior Counsel of Occidental Petroleum Corporation, a Delaware
corporation ("Occidental"), and have acted as counsel to Occidental in
connection with the preparation of the above-referenced Registration Statement
on Form S-8, filed by Occidental with the Securities and Exchange Commission
("Commission") on February 22, 1999 (the "Registration Statement"). The
Registration Statement relates to the registration under the Securities Act of
1933, as amended (the "1933 Act"), of 2,000,000 shares (the "Shares") of Common
Stock, par value $.20 per share, of Occidental. The Shares are to be issued in
accordance with the Occidental Petroleum Corporation Savings Plan (the "Plan").

     In connection with this opinion, I have examined and am familiar with
originals or copies, certified or otherwise identified to my satisfaction, of
such records of Occidental and all such agreements, certificates of public
officials, certificates of officers or other representatives of Occidental and
others and such other documents, certificates and records as I have deemed
necessary or appropriate as a basis for the opinions set forth herein,
including, without limitation, (i) the Registration Statement (together with the

                             Article 2. Definitions
                             ----------------------

     2.1       Definitions.  Whenever used in the Plan the following terms shall

     (a)       "Accounting Date" shall mean the business day coincident with or
               next preceding the fifteenth day of each month and the last day
               of each month.
     (b)       "Adjustment Contributions" shall mean Pretax Deferrals which are
               converted to After-Tax Contributions in order to comply with
               limitations under Code section 415 or to comply with
               nondiscrimination tests of Code section 401(k).
     (c)       "Administrative Committee" means the committee appointed by the
               Board to administer the Plan in accordance with the applicable
               provisions of Article 11 of this Plan.
     (d)       "Affiliate" shall mean a corporation or other employer which is
               controlled by or under common control with the Company, within
               the meaning of sections 414 and 1563 of the Code. The
               determination of control shall be made without reference to
               paragraphs (a)(4) and (e)(3)(C) of section 1563, and solely for
               the purpose of applying the limitations of sections 5.5 through
               5.8 of this Plan, the phrase "more than 50 percent" shall be
               substituted for the phrase "at least 80 percent" each place it
               appears in section 1563(a)(1). In addition, to the extent that
               the context may so require, "Affiliate" shall mean any member of
               an affiliated service group (within the meaning of section 414(m)
               of the Code) to which the Company belongs, and any corporation,
               trade or business which is more than 50 percent owned, directly
               or indirectly, by the Company and is designated by the Board as
               an Affiliate.
     (e)       "After-Tax Contributions" shall mean the amount a Participant
               requests the Company to contribute on his behalf on an after-tax

     (f)       "Alternate Payee" shall have the same meaning as assigned to that
               term in section 414(p)(8) of the Code.
     (g)       "Beneficiary" means the person or persons (who may be named
               contingently or successively) designated by a Participant, an
               Alternate Payee, or a beneficiary of a deceased Participant or a
               deceased Alternate Payee to receive his Personal Savings Account
               in the event of his death. Each Participant, Alternate Payee, and
               beneficiary of a deceased Participant or Alternate Payee, except
               married Participants prior to the day they reach age 35, may
               designate at any time, and any number of times, a beneficiary on
               a form prescribed by the Administrative Committee, and such
               designation will be effective only when filed in writing with the
               Administrative Committee, and shall revoke all prior designations
               by the same Participant or Alternate Payee. The Administrative
               Committee shall require that a married Participant who designates
               a Beneficiary other than his spouse obtain and submit to the
               Administrative Committee the spouse's notarized written consent
               to the designation on a form that discloses to the spouse the
               potential effect of such consent. If a Participant is married and
               is under age 35, then his Beneficiary shall be his spouse. If no
               Beneficiary is designated at the time of the Participant's or
               Alternate Payee's death, or at the time of death of the
               beneficiary of a deceased Participant or Alternate Payee, or if
               no person so designated shall survive the Participant, Alternate
               Payee, or beneficiary of a deceased Participant or Alternate
               Payee, the Beneficiary shall be his spouse, or if the deceased
               individual has no surviving spouse, his surviving children
               equally, or if there are no surviving children, his surviving
               parents equally, or if only one parent is living, his living
               parent, or if no parent is living, his surviving siblings
               equally, or if only one sibling is living, his surviving sibling,
               or if no sibling is living, his estate.
     (h)       "Board of Directors" or "Board" means the Board of Directors of
               Occidental Petroleum Corporation.

               Participant from an Employer for services rendered, including

               the Occidental Petroleum Corporation Pretax Spending Program, but
               excluding (i) bonuses, incentives, overtime, shift differential,

               allowances, including automobile allowances and moving

               than Pretax Deferrals and amounts contributed pursuant to the
               Occidental Petroleum Corporation Pretax Spending Program) to any
               pension plan or plan of deferred compensation, (iv) any amount
               contributed by an Employer (in addition to Pretax Deferrals) to
               this Plan, and (v) any amount paid by an Employer for other
               fringe benefits, such as health and hospitalization, and group
               life insurance benefits, or perquisites, provided that earnings
               of a Participant in excess of $160,000, or such higher amount as
               shall be permitted by the Secretary of the Treasury, in any Plan
               Year shall not be included in Compensation. Compensation will be
               determined in accordance with the following rules:
               (1)  For Participants compensated by salary, the amount of
                    Compensation shall be base salary of record for each pay
                    period, provided, however, that for any salaried Participant
                    whose salary is reduced for a pay period (for reasons other
                    than the making of Pretax Deferrals and contributions
                    pursuant to the Occidental Petroleum Corporation Pretax
                    Spending Program), Compensation will include his actual base
                    salary of record paid to him (subject to the exclusions
                    listed above) not in excess of his salary of record for such
                    pay period.

               (2)  For Participants compensated by commission (primarily truck
                    drivers), the amount of Compensation shall be the amount per
                    pay period (subject to the exclusions listed above) to be
                    reported on Form W-2 for federal tax purposes.
               (3)  For Participants compensated at an hourly rate, the amount
                    of Compensation in a pay period shall be the base hourly
                    rate (subject to the exclusions listed above) multiplied by
                    the number of regularly scheduled hours worked in a pay
                    period. If the Participant's regularly scheduled work week
                    is more than 40 hours, Compensation shall include an
                    additional amount equal to the base hourly rate (subject to
                    the exclusions listed above) times one half the number of
                    regularly scheduled hours worked in excess of 40 in the work
                    week.
               (4)  For Participants compensated on a Twelve Hour Shift Basis,
                    the amount of Compensation for each pay period shall be the
                    Participant's annual base salary of record (including
                    Guaranteed Overtime) divided by the number of pay periods
                    applicable to the Participant during the Plan Year. For the
                    purpose of this subsection 2.1(k), the term "Twelve Hour
                    Shift Basis" means any arrangement whereby Participants work
                    twelve hour daily shifts which may result in alternating
                    work weeks of more and less than forty hours per week.
                    Additionally, for the purpose of this subsection 2.1(k), the
                    term "Guaranteed Overtime" means compensation paid to a
                    Participant for overtime work which the Participant is
                    assigned at the beginning of the year to perform.
               (5)  Compensation shall include vacation pay received in periodic
                    payments and annual vacation payments made to commission
                    paid Employees, but shall not include single sum vacation
                    payments to active or terminating Employees.

               (6)  Compensation shall include base salary or wages received
                    during paid leaves of absence and periodic severance pay,
                    but will not include single sum severance payments.
               (7)  Compensation will not include long-term disability payments
                    and short-term disability payments of less than 100 percent
                    of base pay in effect prior to becoming Disabled.
     (l)       "Disability" or "Disabled" refers to any Participant who is
               determined to be disabled under Section 423 of Title 42 of the U.
               S. Code and who receives disability insurance benefits thereunder
               or any Participant who is a participant in the Occidental
               Petroleum Corporation Long-Term Disability Plan and who is
               determined to be disabled therein under the definition of
               "disability" applicable to the period beginning 24 months after
               the commencement of disability and who receives benefits
               thereunder. Such Participant shall be considered to be Disabled
               as of the time of commencement of benefits as described above.

               A Participant who claims to be Disabled as a result of being
               determined to be disabled under Section 423 of Title 42 of the
               U.S. Code must give written notice thereof to the Administrative
               Committee and submit, at the expense of the Participant, to the
               Administrative Committee such evidence of Disability as the
               Administrative Committee may require. Failure by a Participant to
               comply with the foregoing requirements shall be deemed conclusive
               evidence that such Participant is not Disabled. All rules with
               respect to the determination of Disability shall be uniformly and
               consistently applied to all Participants in similar
               circumstances.
     (m)       "Domestic Overseas Subsidiary" means any corporation or
               unincorporated entity created or organized under the laws of the

               and (iii) which has derived at least 90 percent of its gross

                    agreement expressly provides participation in the Plan;

                    dollars, unless the Plan has been made applicable to such an
                    Employee by the Employer;
               (3)  Employees of a Foreign Subsidiary or Domestic Overseas
                    Subsidiary who are citizens of the United States or Canada
                    and for whom contributions are made under a funded plan of

Affiliate, the length of which shall be determined, in completed years and
months, during the following periods of time:
     (a)       Credit shall be given to an Employee for the period of time

               Employee's Separation from Service.
     (b)       Credit shall be given to an Employee for each period beginning

               date of such Separation from Service.
     (c)       Credit shall be given to an Employee after a Separation from

     (d)       Whenever the total number of years of Service of an Employee must
               be ascertained under this Plan, all noncontinuous periods of
               Service which are credited to such Employee under paragraphs (a),
               (b) and (c) above, shall be aggregated. For purposes of
               aggregating such years of Service, the completed years and months
               credited to an Employee during any period of Service shall be
               added to the number of completed years and months credited to him

            Article 4. Pretax Deferrals, After-Tax Contributions and
            --------------------------------------------------------
                            Adjustment Contributions
                            ------------------------

     4.1       Pretax Deferrals and After-Tax Contributions.  Each Participant
may elect to have the Company contribute to the Plan on his behalf each Plan
Year an amount, in whole percentage points, equal to 1 percent to 12 percent of
his Compensation (or 1 percent to 6 percent of his Compensation in the case of a
Participant who is a participant in the Occidental Petroleum Corporation
Supplemental Retirement Plan) as a Pretax Deferral or After-Tax Contribution, or
any combination in whole percentage points, in accordance with the rules set
forth in sections 4.2, 4.5 and 4.6 and such other rules as the Administrative
Committee may prescribe.
     4.2       Pretax Deferral and After-Tax Contribution Election Procedures.
Elections shall be made available by the Administrative Committee to
Participants and to Employees expected to become Participants. Elections must be
made in accordance with procedures established by the Administrative Committee.
All elections shall apply to Compensation earned during the payroll period
within which the election is processed, and all elections shall be irrevocable
for such period.

If a Participant has a Separation from Service, becomes an Inactive Participant,
or goes on unpaid leave of absence, his Pretax Deferrals, After-Tax
Contributions and Adjustment Contributions shall cease, unless he is reinstated
as a Participant or returns from his leave of absence during the Plan Year, in
which case his Pretax Deferrals, After-Tax Contributions and Adjustment
Contributions may resume.
     4.3       Discontinuance or Change in Rate of Pretax Deferrals and 
After-Tax Contributions.  Pretax Deferral and After-Tax Contribution elections
shall apply automatically to each subsequent payroll period unless a new
election (which may increase, decrease or cancel Pretax Deferrals or After-Tax
Contributions) is filed with the Administrative Committee in accordance with
this section.

                                       21
<PAGE>

A Participant may suspend his Pretax Deferrals, After-Tax Contributions and
Adjustment Contributions on the first day of any payroll period by giving notice
in accordance with procedures established by the Administrative Committee. Such
suspension may last indefinitely. A Participant may resume his Pretax Deferrals,
After-Tax Contributions and Adjustment Contributions on the first day of any
payroll period after the effective date of the prior suspension, by giving
notice in accordance with procedures established by the Administrative
Committee.

A Participant may change the rate of his Pretax Deferrals, After-Tax
Contributions and Adjustment Contributions to a different percentage that is
permitted under section 4.1 as of the first day of any payroll period. Such
change shall be made by submitting a new election in accordance with procedures
established by the Administrative Committee.
     4.4       Salary Reduction.  Each Participant who makes a Pretax Deferral
election described in section 4.1 to have the Employer contribute a percentage
of his Compensation to this Plan shall, by the act of making such election, have
his salary reduced by an equivalent percentage for so long as the election
remains in effect.
     4.5       Individual Maximum Pretax Deferrals and After-Tax Contributions.
The Pretax Deferral and After-Tax Contribution election of a Participant shall
be adjusted in whole percentages, if necessary, from time to time as determined
by the Administrative Committee so that such Pretax Deferrals and After-Tax
Contributions for the Plan Year will not exceed (a) less (b) below, where:
     (a)       is the lesser of,
               (1)  25 percent of Taxable Compensation, or
               (2)  $30,000 (or such other dollar maximum as may be permitted by
                    the Internal Revenue Service), and
     (b)       is the sum of:

                                       22
<PAGE>

               (1)  Employer contributions projected for the Participant as if
                    he were a Participant under the Retirement Plan for a full
                    Plan Year; plus
               (2)  Matching contributions expected to be allocated to the
                    Participant under this Plan (based on any such allocations
                    already made and the Participant's current Pretax Deferral
                    and After-Tax Contribution election) for a full Plan Year.

Any adjustment in the elected percentage of a Participant, and the resulting
adjustment in salary reduction under section 4.4, shall take effect in the month
of such adjustment calculation and shall remain in effect as a maximum Pretax
Deferral level for the Participant for the rest of the Plan Year, unless further
adjusted by the Administrative Committee. In the case of a Participant who has
elected Pretax Deferrals and After-Tax Contributions in the same Plan Year, any
adjustment which must be made under this section for a Participant shall be made
first to the Participant's After-Tax Contributions. If additional adjustments
are required under this section after the Participant's After-Tax Contributions
percentage is reduced to zero, such adjustments shall be made to the
Participant's Pretax Deferrals.

Notwithstanding anything herein to the contrary, under no circumstances may a
Participant's Pretax Deferral in any calendar year exceed $10,000 (or such
higher amount as the Secretary of the Treasury shall establish from time to time
pursuant to Code section 402(g)(5)).
     4.6       Discrimination Limits on Pretax Deferrals.  Prior to the
beginning of each Plan Year and at any other time during the Plan Year that the
Administrative Committee may deem appropriate, the following test shall be made
to prevent the Pretax Deferrals under the Plan from becoming discriminatory.

                                       23
<PAGE>

In no event shall any Employer make Pretax Deferrals for any Plan Year that
would result in the actual deferral percentage ("ADP") for the Plan Year of the
group of Highly Compensated Employees eligible to participate in the Plan
exceeding the greater of:

     (A)       For Plan Years beginning prior to January 1, 1998:

     (i)       One and one-quarter times the ADP for the current Plan Year of
               the group of all other Eligible Employees; or

     (ii)      The lesser of (i) two times the ADP for the current Plan Year of
               the group of all other Eligible Employees, or (ii) the ADP for
               the current Plan Year of the group of all other Eligible
               Employees plus two percentage points.

     (B)       For Plan Years beginning after December 31, 1997:

     (i)       One and one-quarter times the ADP for the preceding Plan Year of
               the group of all other Eligible Employees; or

     (ii)      The lesser of (i) two times the ADP for the preceding Plan Year
               of the group of all other Eligible Employees, or (ii) the ADP for
               the preceding Plan Year of the group of all other Eligible
               Employees plus two percentage points.

The ADP of each group of Eligible Employees for any Plan Year shall be the
average of the ratios (calculated separately for each Eligible Employee in each
group after making any adjustments required under section 4.5) of (I) the Pretax
Deferrals made on behalf of each Eligible Employee for such Plan Year to (II)
such Eligible Employee's ADP Testing Compensation, earned while such Employee
was an eligible employee within the meaning of Treasury regulation section
1.401(k)-1(g)(4)(i) for such Plan Year.

                                       24
<PAGE>

For purposes of making these determinations, an Employee will be considered to
be a "Highly Compensated Employee" in the current Plan Year if he:
     (a)       is a 5% Owner in the current or preceding Plan Year; or
     (b)       has Highly Compensated Test Compensation during the preceding
               Plan Year of more than $80,000 (or such higher amount as the
               Secretary of the Treasury shall establish from time to time
               pursuant to Code section 414(q)(1)).

In applying the $80,000 limit described in subsection (b) above, the
Administrative Committee may elect to limit the determination of Highly
Compensated Employees to that group of Employees consisting of the top 20% of
such Employees ranked on the basis of Compensation received during the Plan
Year.

For the purposes of identifying "Highly Compensated Employees" and for applying
the ADP test described above, the following special rules and definitions will
apply:
     (i)       An Employee who has Separated from Service will continue to be a
               Highly Compensated Employee if he was a Highly Compensated
               Employee at the time he Separated from Service, or if he was a
               Highly Compensated Employee at any time after he attained age 55.
               This determination shall be based on the definition of highly
               compensated employee under Code section 414(q) and related
               regulations in effect for that determination year.
     (ii)      The term "current Plan Year" shall mean the Plan Year for which
               the determination is being made.
     (iii)     The term "preceding Plan Year" shall mean the Plan Year
               immediately preceding the current Plan Year.
     (iv)      An Employee shall be considered a "5% Owner" for a Plan Year if
               at any time during such Plan Year he was a 5-percent owner (as
               defined in Code section 416(i)(1)) of the Company.

                                       25
<PAGE>

     (v)       The term "Highly Compensated Test Compensation" shall mean
               compensation within the meaning of Code section 415(c)(3).
     (vi)      The term "ADP Testing shall mean compensation within the meaning
               of Code section 414(s)(1), except that the Administrative
               Committee may elect not to include in such compensation any
               amount which is contributed by the Employer pursuant to a salary
               reduction agreement and which is not includable in gross income
               of the Employee under Code section 125, 402(e)(3), 402(h), or
               403(b).
     4.7       Discrimination Limits on Matching Contributions, After-Tax
Contributions, and Adjustment Contributions. Prior to the beginning of each Plan
Year and at any other time during the Plan Year that the Administrative
Committee may deem appropriate, the following test shall be made to prevent
Employer matching contributions, After-Tax Contributions and Adjustment
Contributions under the Plan from becoming discriminatory.

In no event shall any Employer make matching contributions, After-Tax
Contributions and Adjustment Contributions for any Plan Year that would result
in the actual contribution percentage ("ACP") for the Plan Year of the group of
Highly Compensated Employees eligible to participate in the Plan exceeding the
greater of:

     (A)       For Plan Years beginning prior to January 1, 1998:
     (i)       One and one-quarter times the ACP for the current Plan Year of
               the group of all other Eligible Employees; or
     (ii)      The lesser of (i) two times the ACP for the current Plan Year of
               the group of all other Eligible Employees, or (ii) the ACP for
               the current Plan Year of the group of all other Eligible
               Employees plus two percentage points.

                                       26
<PAGE>

     (B)       For Plan Years beginning after December 31, 1997:
     (i)       One and one-quarter times the ACP for the preceding Plan Year of
               the group of all other Eligible Employees; or (ii) The lesser of
               (i) two times the ACP for the preceding Plan Year of the group of
               all other Eligible Employees, or
     (ii)      the ACP for the preceding Plan Year of the group of all other
               Eligible Employees plus two percentage points.

For purposes of making these determinations, the term "Highly Compensated
Employee" shall have the same meaning as set forth in section 4.6. The "ACP" for
a specified group of Eligible Employees for any Plan Year is the average of the
ratios (calculated separately for each Eligible Employee in such group) of the
sum of Employer matching contributions, After-Tax Contributions and Adjustment
Contributions paid for each such Eligible Employee for such Plan Year to the ADP
Testing Compensation paid to the Eligible Employee for such Plan Year, provided,
however, that in accordance with Treasury regulations, the Administrative
Committee may elect to take into account, in computing average contribution
percentage, Pretax Deferrals or any elective deferrals and qualified nonelective
contributions under this Plan or any other plan maintained by the Company. The
term "ADP Testing Compensation" shall have the same meaning as set forth in
section 4.6. For the purpose of this section 4.7, the terms "elective deferrals"
and "qualified nonelective contributions" shall have the same meaning as in Code
section 401(m)(4).
     4.8       Multiple Use Limitation.  If, as a result of the testing
described in sections 4.6 and 4.7, each of the four conditions described in
Treasury Regulation section 1.401(m) - 2(b)(1) exist in spite of any reductions
which may be made pursuant to subsections 4.9(b) and 4.9(c), then the
Administrative Committee shall reduce the Pretax Deferrals elected by the
Participants who are Highly Compensated Employees in the manner described in
subsections 4.9(a) or 4.9(b). The reduction shall be made as necessary to
prevent any one of the four conditions described above

                                       27
<PAGE>

from occurring. For the purpose of this section 4.8, the term "Highly
Compensated Employee" shall have the meaning set forth in section 4.6.
     4.9       Reductions to Pretax Deferrals and After-Tax Contributions.
     (a)       If it becomes necessary for the Administrative Committee to
               reduce the Pretax Deferral of a Participant during the current
               Plan Year as a result of (i) the operation of the last paragraph
               of section 4.5, (ii) the Plan's expected failure to comply with
               the actual deferral percentage test pursuant to section 4.6, or
               (iii) the Plan's expected failure to comply with the multiple use
               limitation of section 4.8, then the difference between the
               percentage elected by the Participant and the percentage as
               reduced shall, absent a contrary instruction from the Participant
               on his Pretax Deferral election form, be contributed by the
               Participant as an Adjustment Contribution through regular payroll
               deductions.

               In the case of a Participant who is making a contribution under
               this subsection, any election to increase, decrease, or
               discontinue Pretax Deferrals under section 4.3 shall increase or
               decrease contributions under this subsection first before
               changing Pretax Deferrals.

     (b)       To the extent necessary to conform to the limitations contained
               in sections 4.6 and 4.8 after the close of the Plan Year, the
               Administrative Committee shall reduce Pretax Deferrals made on
               behalf of Highly Compensated Employees. Such reduction shall be
               effected by reducing Pretax Deferrals made on behalf of Highly
               Compensated Employees sequentially and in descending order,
               beginning with:

               (1)  For Plan Years beginning before January 1, 1997, the Highly
                    Compensated Employee who elected the highest percentage of
                    such contributions; and

                                       28
<PAGE>

               (2)  For Plan Years beginning after December 31, 1996, the Highly
                    Compensated Employee who elected the largest dollar amount
                    of such contributions;

               and continuing as needed to conform to such limitations.

               Any such reduction in the Pretax Deferrals made on behalf of any
               Participant shall be refunded to the Participant as soon as
               administratively possible, together with any earnings allocable
               to such excess contributions for the Plan Year for which the
               excess contributions were made and for the period between the end
               of that Plan Year and the date of distribution, as provided in
               the rules adopted by the Administrative Committee at the time. In
               no event, however, shall such excess contributions or such
               earnings allocable thereto be left undistributed any later than
               the last day of the Plan Year following the Plan Year in which
               such excess contributions were made.

     (c)       To the extent necessary to conform to the limitations contained
               in section 4.7 after the close of the Plan Year, the
               Administrative Committee shall reduce the After-Tax Contributions
               or Employer matching contributions made on behalf of Highly
               Compensated Employees. Such reduction shall be effected by
               reducing After Tax Contributions or Employer matching
               contributions made on behalf of Highly Compensated Employees
               sequentially and in descending order, beginning with:

               (1)  For Plan Years beginning before January 1, 1997, the Highly
                    Compensated Employee who elected the highest percentage of
                    such contributions; and

                                       29
<PAGE>

               (2)  For Plan Years beginning after December 31, 1996, the Highly
                    Compensated Employee who elected the largest dollar amount
                    of such contributions;

               and continuing as needed to conform to such limitations.

               Any such reduction in After-Tax Contributions, Adjustment
               Contributions or vested Employer matching contributions made on
               behalf of any Participant shall be refunded to the Participant as
               soon as administratively possible, together with any earnings
               allocable to such excess aggregate contributions for the Plan
               Year for which the excess aggregate contributions were made and
               for the period between the end of that Plan Year and the date of
               distribution, as provided in the rules adopted by the
               Administrative Committee at the time. In no event, however, shall
               such excess aggregate contributions or such earnings allocable
               thereto be left undistributed any later than the last day of the
               Plan Year following the Plan Year in which such excess
               contributions were made.

If there is a loss allocable to the excess aggregate contribution, the excess
aggregate contributions to be distributed to a Participant shall in no event be
less than the lesser of the Participant's Account under the Plan or the
Participant's After-Tax Contributions, Adjustment Contributions and Employer
matching contributions for the Plan Year. Excess aggregate contributions shall

For the purpose of this section 4.9, the term "Highly Compensated Employee"
shall have the meaning set forth in section 4.6.
     4.10      Deposit of Pretax Deferrals,  After-Tax Contributions and
Adjustment Contributions.  The amount to be contributed to the Plan because of
Participants' elections under section 4.1 shall be paid out of the Employer's
funds and shall be deposited in the Trust Fund as soon as practicable after the
payment date for each payroll period. Adjustment Contributions shall be
deposited in the Trust Fund at the same time as contributions under section 4.1.
     4.11      Crediting of Pretax Deferrals, After-Tax Contributions and
Adjustment Contributions.  The amounts contributed to the Trust Fund under

of this section 4.12, "excess deferral amount" shall mean the amount of Pretax
Deferrals for a calendar year that the Participant allocates to this Plan
pursuant to the claim procedure set forth below.

The Participant's claim shall be in writing, shall be submitted to the
Administrative Committee no later than March 1, shall specify the Participant's
excess deferral amount for the preceding calendar year, and shall be accompanied
by the Participant's written statement that if such amounts are not distributed,
such excess deferral amount, when added to amounts deferred under other plans or
arrangements described in sections 401(k), 408(k), or 403(b) of the Code,
exceeds the limit imposed on the Participant by section 402(g) of the Code for
the year in which the deferral occurred.

                                       31

The excess deferral amount distributed to a Participant with respect to a
calendar year shall be adjusted for income and, if there is a loss allocable to
the excess deferral, shall in no event be less than the lesser of the
Participant's Account or the Participant's Pretax Deferrals for the Plan Year.

                   Article 5. Employer Matching Contributions
                   ------------------------------------------

     5.1       Employer Matching Contributions.  Each Participant for whom a
Pretax Deferral, an After-Tax Contribution or an Adjustment Contribution was
made during a month shall be entitled to an additional allocation equal to 75
percent of the contributions under section 4.1 and section 4.9 allocable to him
for the month, provided that the additional allocation cannot be based on more
than 6 percent of Compensation.

Allocations to be made for any Participant for any Plan Year under this section
5.1 shall be limited to the extent necessary to prevent Annual Additions of the
Participant from exceeding the limits of section 5.5.

The Employer shall contribute an amount which, when added to forfeitures, is
sufficient to provide the required allocations.
     5.2       Deposit of Employer Matching Contributions.  To the extent not
provided from forfeitures in accordance with section 5.4, Employer matching
contributions shall be paid out of funds in the manner specified in section
4.10. Such contributions shall be deposited and posted to the Trust Fund as soon
as practicable after the end of the payroll period for which they are made.
     5.3       Crediting of Employer Matching Contributions.  The allocations
required under section 5.1 shall be credited to the Matching Account of any
Participant who is entitled to such an allocation as of the date on which the
matched Pretax Deferrals, After-Tax Contributions and Adjustment Contributions
are credited.
     5.4       Forfeitures.  The Administrative Committee shall use forfeitures
occurring in any month to reduce Employer matching contributions for such month
and future months. Forfeitures shall be used to reduce matching contributions of
all Employers without regard to whether the forfeitures are attributable to
persons employed by any individual Employer. If the

                                       33
<PAGE>

amount of forfeitures occurring in a month exceeds the amount of matching
allocations to be made for such month, then the excess shall be held in a
suspense account and allocated in lieu of Employer matching contributions in
succeeding months. No Employer matching contributions shall be made until any
balance in the suspense account is exhausted, and if the Plan terminates while
such a balance exists, the balance shall be allocated in proportion to the
Compensation of all Participants for the Plan Year to the extent of the maximum
amount permitted under section 5.5.
     5.5       Limitation on Annual Additions.  Notwithstanding anything to the
contrary contained in this Plan, the total Annual Additions under this Plan and
any other defined contribution plan, as defined in section 414(i) of the Code,
maintained by the Employer or any other Affiliate, to a Participant's Account
for any Plan Year, which shall be the limitation year for purposes of section
415 of the Code, shall not exceed the lesser of:
     (a)       $30,000,  or such higher amount as may be permitted by the
               Secretary of the Treasury pursuant to Code section 415(d), or
     (b)       25 percent of the Participant's Taxable Compensation for the
               limitation year.
     5.6       "Annual Addition" Defined.  For purposes of section 5.5, the term
"Annual Addition", with respect to any Participant for a Plan Year shall mean
the aggregate of:
     (a)       the amount of Employer contributions (including Pretax Deferrals)
               and forfeitures allocated to the Participant's account under this
               Plan and any other defined contribution plan, as defined in
               section 414(i) of the Code, maintained by the Employer or any
               other Affiliate for the Plan Year;
     (b)       the amount of a Participant's After-Tax Contributions made during
               such Plan Year; and
     (c)       For the purpose of subsection (a) of section 5.5 only, the amount
               of Employer contributions, if any, allocated to an account
               described in Code section 419A(d)(1) or an account described in
               Code section 415(l)(2).

                                       34
<PAGE>

     5.7  Other Defined Contribution Plans.  If the Company or any
nonparticipating Affiliate maintains any other qualified defined contribution
plan for its Employees, some or all of whom are Participants of this Plan, then
any such Participant's Annual Additions (after reductions required under the
provisions of such other plan or plans) shall first be reduced under such other
plan and then shall be reduced under this Plan, if such reduction is required
for purposes of reducing allocations on a combined basis, to the limits of
section 5.5.
     5.8       Defined Benefit Plans.
     (a)       If a Participant in this Plan was also a Participant in a defined
               benefit plan, as defined in section 414(j) of the Code, to which
               contributions were made by the Employer or any other Affiliate,
               then in addition to the limitations contained in section 5.5 of
               this Plan, the allocations of the Participant under this Plan
               shall be limited to the extent necessary to comply with the
               limitation set forth in section 415(e) of the Code. For this
               purpose, the Defined Benefit Fraction shall be computed and the
               Defined Contribution Fraction shall be adjusted (as provided in
               section 5.7) so that the sum of these fractions shall not exceed
               1.0.
     (b)       For purposes of this section 5.8, the following definitions shall
               apply:
               (i)  "Defined Benefit Fraction" shall mean a fraction, the
                    numerator of which is the aggregate of the projected annual
                    benefits (determined as of the last day of the Plan Year) of
                    the Participant under all defined benefit plans (whether or
                    not terminated) maintained by the Employer or any other
                    Affiliate, and the denominator of which is the lesser of (x)
                    the product of 1.25 multiplied by the dollar limitation in
                    effect under section 415(b)(1)(A) of the Code for such year,
                    or (y) the product of 1.4 multiplied by the amount which may
                    be taken into account under section 415(b)(1)(B) of the Code
                    with respect to the Participant under all such defined
                    benefit plans for such year.

                                       35
<PAGE>

               (ii) "Defined Contribution Fraction" shall mean a fraction, the
                    numerator of which is the sum of the Annual Additions to the
                    Participant's Account under this Plan and any other defined
                    contribution plan as defined in section 414(i) of the Code
                    maintained by the Employer or any other Affiliate for such
                    Plan Year, and all prior Plan Years, and the denominator of
                    which is the sum, for such Plan Year and each prior year of
                    Service with the Employer or any other Affiliate, of the
                    lesser of (x) the product of 1.25 multiplied by the dollar
                    limitation in effect under section 415(c)(1)(A) of the Code
                    for such year (determined without regard to section
                    415(c)(6) of the Code), or (y) the product of 1.4 multiplied
                    by the amount which may be taken into account under section
                    415(c)(1)(B) of the Code with respect to the Participant
                    under all such defined contribution plans for such year.
     5.9       Deductibility Limitation.  The dollar amount of Company
contributions, as provided under sections 4.1 and 5.1, shall be limited to the
amount deductible under section 404 of the Code for the taxable year for which
such contributions are paid.
     5.10      Adjustment of Allocations. Allocations to the Accounts of a
Participant in excess of the limit of section 5.5 cannot occur because of
limitations on allocations set forth in sections 4.5, 5.1 and 5.4. However, if
an allocation to the Account of a Participant would exceed the limit of section
5.5 due to a reasonable mistake in estimating a Participant's Compensation, then
any amount which cannot be allocated shall be held in a suspense account and
shall be allocated to the account of such Participant in the next following Plan
Year, to the maximum extent permitted under section 5.5.

<PAGE>

Every Participant, spousal Beneficiary, or Alternate Payee who receives a

     6.3       Forfeiture of Contingent Interests.  Any portion of a

provisions of section 6.1 upon his Separation from Service shall be forfeited.
If the Participant is rehired, then the cash value (determined at the time of

Account by making a special allocation out of forfeitures. The restoration of
any amounts forfeited is based on the following provisions:
     (a)       Any Participant who Separated from Service less than fully
               vested on or after January 1, 1982 will have his forfeitures
               restored upon rehire. Upon restoration, a separate account will
               be established, which will be credited by the amount of the
               forfeiture. The Participant's vested portion in this restoration
               account, at the time of the restoration and at any relevant time
               thereafter, shall be the greater of
               (i)  the Participant's vested percentage in his Matching Account,
                    as determined under section 6.1, multiplied by the balance
                    in this restoration account, or
               (ii) the Participant's vested percentage in his Matching Account,
                    as determined under section 6.1, multiplied by the excess of
                    the sum of the balance in this restoration account and the
                    amount of the distribution over the amount of the
                    distribution.

                                       42
<PAGE>

     (b)       Any Participant who Separated from Service less than fully vested
               on or after January 1, 1981 will have his forfeitures restored,
               if he is rehired on or before December 31, 1982.
     (c)       Any Participant who Separated from Service less than fully vested
               prior to January 1, 1981 and was not rehired prior to January 1,
               1984 will not be entitled to a restoration of forfeitures.

Notwithstanding the foregoing, any individual who was a participant in the
MidCon Corp. ESOP and who, prior to December 18, 1997, incurred a Separation
from Service shall, upon becoming an Employee, have the unvested portion of his
account under the MidCon Corp. ESOP, determined as of the Valuation Date
coinciding with or immediately preceding the date of such Separation from
Service, restored to a Rollover Account under the Plan. The Employer shall
restore any such amounts by making a special allocation out of forfeitures
available for reallocation in the Plan Year of the restoration, provided that if
such forfeitures are insufficient for such restoration, the Employer shall make
a special contribution in cash for purposes of such restoration. Any amount
restored to a Rollover Account under this section shall be fully vested and
nonforfeitable.
     6.4       Death Benefits.  Should a Participant die while he is still
employed by the Company or an Affiliate, or after a Separation from Service but
prior to distribution of his Personal Savings Account, the balance of said
deceased Participant's Personal Savings Account, valued as provided in Article
9, shall be distributed to his Beneficiary as soon as practicable after the
Participant's death. Distribution of the deceased Participant's Personal Savings
Account shall be in the form of an immediate annuity for the life of the
Beneficiary with monthly payments as provided in subsection 6.5(c), in an
immediate lump sum payment, or in an immediate 10-year term certain and
continuous annuity with monthly payments as provided in subsection 6.5(e), as
the Beneficiary may elect prior to the receipt of a benefit on a form filed with
the Administrative Committee, provided that if the Participant has designated
more than one Beneficiary,

                                       43
<PAGE>

distribution shall be made in the form of a lump sum, with payment to be made to
all Beneficiaries concurrently as soon as possible after death. Additionally, a
Beneficiary who is the Participant's spouse may elect, prior to receipt of a
benefit, on a form filed in accordance with procedures established by the
Administrative Committee, to defer receipt of payment of the deceased
Participant's Personal Savings Account, but not beyond December 31 of the year
which includes the date the Participant would have attained age 70 1/2, or to
take a partial cash distribution as provided in subsection 6.5(b). In the
absence of an election otherwise, the benefit shall be paid to the Beneficiary
in an immediate lump sum. Notwithstanding the above, in the case of a
Beneficiary which is a trust or an estate, distribution shall be made in an
immediate lump sum payment.

     Should an Alternate Payee or the Beneficiary of a deceased Participant or
Alternate Payee die prior to distribution of a separate Account established on
his behalf, the balance of said deceased individual's Account, valued as
provided in Article 9, shall be distributed to his Beneficiary as soon as
practicable after his death. Such distribution shall be made in the form of a
lump sum.

In the case of a Beneficiary of a Participant for whom a direct plan-to-plan
transfer was made to this Plan from the Laurel Industries Inc. Incentive Savings
Plan (the "Laurel Plan"), distribution may be made, at the election of the
Beneficiary, in any form described in section 6.6(g)(1)(ii) of the Laurel Plan
as in effect on December 31, 1996, provided that the amount subject to such
election shall not exceed the amount of the Beneficiary's Account attributable
to such transfer.
     6.5       Forms of Payment.  Every Participant who Separates from Service
for any reason other than death or an event described in Code section
401(k)(10)(A) shall have the vested portion of his Personal Savings Account
distributed to him under one of the following distribution options selected by
the Participant on a form prescribed by the Administrative Committee:

                                       44
<PAGE>

     (a)       One lump sum payment; or
     (b)       A partial cash distribution in a specified dollar amount,
               provided that a Participant may request a partial cash
               distribution only after five months have elapsed since the last
               such request by the Participant has been processed; or
     (c)       An immediate straight life annuity providing monthly payments for
               the life of the Participant. No monthly payments will be made
               after the Participant's death; or
     (d)       An immediate joint and survivor annuity providing monthly
               payments for the Participant's lifetime. Upon the Participant's
               death, 50, 75, or 100 percent of the monthly payment, whichever
               is elected by the Participant, will continue for the lifetime of
               the Beneficiary if the Beneficiary survives the Participant; or
     (e)       An immediate 10-year term certain annuity which provides monthly
               payments for the life of the Participant with a guarantee that a
               minimum of 120 such payments will be made even if the Participant
               dies before receiving all of them. The Participant's Beneficiary
               will receive the remaining payments; or
     (f)       Deferral of receipt of payment of the vested portion of his
               Personal Savings Account, but not beyond December 31 of the
               calendar year of the Participant's attainment of age 70 1/2,
               provided that a Participant who elects a deferral of payment
               under this subsection (f) may not request a partial cash
               distribution under subsection (b) subsequent to his attainment of
               age 70 1/2.

A Participant who Separates from Service as a result of an event described in
Code section 401(k)(10)(A), and who would not otherwise be considered to have
Separated from Service, shall have the vested portion of his Personal Savings
Account distributed to him in one lump sum payment.

The Company does not guarantee the benefits described in subsections (c), (d),
and (e) above. In the event of the failure of the issuer of an annuity to comply
with its obligations under an annuity

                                       45
<PAGE>

contract purchased by the Plan, the Participant's, Beneficiary's, or Alternate
Payee's remedy will be limited to his claim against the issuer.

The failure of a Participant to make a selection as described above upon his
Separation from Service will be deemed to be an election by the Participant to
defer the commencement of his benefits.

A Participant who elects to receive a partial cash distribution pursuant to
subsection (b) may not make a subsequent request for a lump sum payment pursuant
to subsection (a) or an immediate annuity pursuant to subsection (c), (d), or
(e) for a period of one month beginning with the date of the processing of his
partial cash distribution.

If distribution is to be made in the form of an immediate annuity, then the
balance of the Participant's Personal Savings Account shall be used to purchase
an immediate non-transferable commercial annuity contract which shall be
distributed to the Participant.

The automatic distribution option to a Participant shall be a lump sum payment.

In the case of a Participant who elects to receive a benefit pursuant to
subsection (d) or subsection (e) above, the present value of the payments to be
made to the Participant must be more than 50 percent of the present value of the
total payments to be made to the Participant and his Beneficiary.

An election form shall be provided to the Participant in non-technical language
and shall contain (i) a general description of the distribution options and the
relative financial effect of each option, and (ii) notification that such
Participant may subsequently request to receive an additional written
explanation in non-technical language, of the terms, conditions and projected
financial

                                       46
<PAGE>

impact of one or more of the distribution options (in terms of dollars per
projected monthly annuity payment).

Any election by a married Participant to receive his benefits in the form of an
annuity other than an immediate 50 percent, 75 percent or 100 percent joint and
survivor annuity with his spouse as joint annuitant must be accompanied by a
signed, notarized written consent from the spouse on a form prescribed by the
Administrative Committee, which consent shall state that potential effect to
such spouse of consenting to such an election. Such consent must designate a
Beneficiary (or form of benefits) which may not be changed without spousal
consent, provided that the consent of the spouse may expressly permit
designations by the Participant without any requirement for further consent by
the spouse. Any election of a form of distribution under this section must be
filed in accordance with procedures established by the Administrative Committee
during an election period of not more than 90 days and, except as provided
below, not less than 30 days ending on the day prior to the date as of which his
benefits are scheduled to commence; provided, however, that if the Participant
makes a timely request to receive additional information, as described above,
the election period shall not end prior to 30 days following the furnishing of
such information. A Participant may revoke an election of any benefit form
described in this section and choose again to take any form of benefit available
to him hereunder at any time and any number of times within the above election
period. Notwithstanding the previous two sentences, a Participant, after having
received the written description described in this section, may reject the
automatic election described in this section and elect a different option, in
the manner described above, even though the written description was provided
less than 30 days prior to his benefit commencement date, so long as the
conditions contained in Treasury Regulation section 1.417(e)-1T(b)(3)(ii) have
been met. If the Participant makes an untimely request for additional
information, the Administrative Committee, at its discretion, may grant such
request, but the granting of such request shall not result in the extension of
the election period.

                                       47
<PAGE>

In the case of an Alternate Payee who becomes entitled to receive his Account
pursuant to an appropriate domestic relations order, where the order so permits,
or where the order is silent as to the form of payment to be made, his Account
shall be distributed to him in the form of a lump sum payment pursuant to option
(a) above, or in the form of a lump sum payment pursuant to option (f) above, as
the Alternate Payee may select on a form to be prescribed by the Administrative
Committee. In the absence of such a selection by an Alternate Payee, his Account
will be distributed to him in the form of a lump sum payment pursuant to option
(a) above. Where an order so permits, an Alternate Payee's Account may be
distributed to him in the form of an immediate straight life annuity providing
monthly payments for the life of the Alternate Payee, a partial cash
distribution as described under option (b) above, an immediate 50 percent, 75
percent or 100 percent joint and survivor annuity, or an immediate 10-year term
certain annuity which provides monthly payments for the life of the Alternate
Payee with a guarantee that a minimum of 120 such payments will be made even if
the Alternate Payee dies before receiving all of them; in that event the
Alternate Payee's Beneficiary will receive the remaining payments.

In the case of a Participant, Beneficiary or Alternate Payee receiving a
distribution in the form of one lump sum payment, pursuant to option (a) above,
or as a lump sum payment under option (f) above, the value of his vested
interest attributable to investments other than Stock shall be paid in cash when
distributed, and the vested interest that is attributable to Account balances
consisting of Stock shall be distributed in full shares of Stock plus cash
representing the value of any fractional share. However, by written notice to
the Administrative Committee, the Participant, Beneficiary or Alternate Payee
may elect to receive cash in such amount as may be provided by the value (as
determined under Article 9) of the Stock that would otherwise be distributed to
him. Such a Participant may elect to receive of all or a portion of his Account
in the form of whole shares of Stock, plus cash for any fractional share,
provided that any such election shall be

                                       48
<PAGE>

implemented in accordance with administrative procedures established by the
Administrative Committee by transferring the investment of such Account or
portion thereof, as applicable, (including without limitation amounts
transferred from the MidCon Corp. ESOP) as soon as practicable to the OPC Stock
Fund and distributing such amounts as soon as practicable thereafter.

In the case of a Participant for whom a direct plan-to-plan transfer was made to
this Plan from the Laurel Industries Inc. Incentive Savings Plan (the "Laurel
Plan"), distribution may be made, at the election of the Participant, in any
form described in section 6.5(b)(2) of the Laurel Plan as in effect on December
31, 1996, provided that the amount subject to such election shall not exceed the
amount of the Participant's Account attributable to such transfer.
     6.6       Time of Payment of Benefits.  Distribution of benefits to a
Participant who Separates from Service shall begin not later than the 60th day
after the close of the Plan Year in which occurs the later of (i) the
Participant's Separation from Service, or (ii) the Participant's 65th birthday,
unless the Participant chooses a later payment under section 6.2. If for any
reason the amount which is required to be paid cannot be ascertained on the date
payment would be due hereunder, payment or payments shall be made not later than
60 days after the earliest date on which the amount of such payment is
ascertained.

In the case of an Alternate Payee who is entitled to receive benefits under this
Plan, distribution of benefits may be made at any time that the governing order
may permit, irrespective of the Participant's age and irrespective of whether
the Participant has Separated from Service, so long as either the amount to be
distributed to the Alternate Payee does not exceed $5,000 or the Alternate Payee
consents in writing to the distribution.
     6.7  Withdrawals.  Any Participant or Inactive Participant who is actively
employed by the Company or an Affiliate may withdraw any amount or shares, up to
100 percent of the sum of (i) such Participant's Employee Account, (ii) his
Matching Account if the Participant is

                                       49
<PAGE>

fully vested in such Account, and (iii) his Rollover Account, if any, to the
extent permissible, provided that no withdrawal request may be made during the
five-month period beginning with the date the Participant's or Inactive
Participant's most recent withdrawal request was processed. Any Participant or
Inactive Participant who has attained age 59 1/2 may also withdraw any amount or
shares in his Pretax Deferral Account under this section. A Participant or an
Inactive Participant shall be prohibited from requesting a withdrawal in any
semimonthly processing period in which a loan distribution is being processed.

Application for a withdrawal shall be made on such forms as the Administrative
Committee prescribes and shall be effective as of the end of the semimonthly
processing period in which such application is received by the Administrative
Committee. The Administrative Committee shall direct the Trustee, in such cases,
to pay the Participant or Inactive Participant the amount so requested in a
single sum.

Every Participant who receives a withdrawal which is an eligible rollover
distribution (as defined in Code section 402(c)(4)) shall be entitled to direct
the Administrative Committee to transfer all or part of the taxable portion of
his withdrawal to any eligible retirement plan (as defined in Code section
402(c)(8)(B)) which provides for the receipt of such direct transfers. The
Administrative Committee shall, within a reasonable period of time before making
an eligible rollover distribution, provide to the recipient a copy of the
written explanation required by Code section 402(f).

A withdrawal from a Participant's Account balances invested in Stock shall be in
the form of full shares of Stock and cash representing any fractional share,
except that cash shall be paid in lieu of full shares of Stock if the
Participant specified in his written request for withdrawal that the withdrawal
be in the form of cash. A withdrawal from account balances invested in assets
other

                                       50
<PAGE>

than Stock shall be paid in cash. A withdrawal consisting of pre-1987
contributions from the Employee Account only shall be in the form of cash.

Withdrawals shall be paid first out of the net cumulative pre-1987 contributions
from the Employee Account. Withdrawals shall then be paid out of the net
cumulative post-1986 contributions, together with earnings thereon, on a prorata
basis, from the Employee Account. Additional amounts shall be withdrawn, if
needed, from earnings on pre-1987 contributions from the Employee Account, then
from the Rollover Account, if any, to the extent permissible, then from the
Pretax Deferral Account if permissible, and then from the Matching Account. If a
Participant withdraws any amount from the Matching Account on or after April 1,
1988, the Participant (other than a Participant who has attained age 59 1/2 at
the time the withdrawal is requested, and who withdraws the entire balance in
his Personal Savings Account) shall not be permitted to make any Pretax
Deferrals, After-Tax Contributions or Adjustment Contributions, or receive
Company Matching Contributions for a period of six calendar months after the
withdrawal is processed. The preceding sentence shall be inapplicable in the
case of a withdrawal effected by a creditor of a Participant pursuant to any
insolvency proceeding initiated under federal or state law or pursuant to any
tax levy.
     6.8       Debiting of Investment Funds.  If a Participant making less than
a total withdrawal of his Accounts under section 6.7, or receiving a
distribution of excess deferral amounts under section 4.12, has his Accounts
invested in more than one Investment Fund, the amount withdrawn from his
Accounts shall be withdrawn from such Investment Fund or combination of
Investment Funds in which the Employee has invested on a prorata basis.

If a Participant receives a partial cash distribution under section 6.5(b), the
amount distributed from his Accounts shall be withdrawn from his Investment
Funds on a pro-rata basis within each such Account as follows: first, his
Employee Account, then his Rollover Account, then his Pretax Deferral Account,
and then his Matching Account.

                                       51
<PAGE>

     6.9       Small Amounts.  If the vested balance of a Participant's Personal
Savings Account is $5,000 or less when he or his Beneficiary becomes entitled to
a benefit under sections 6.4 or 6.5, then distribution shall be made in the form
of a lump sum payment, partial cash distribution, or a deferral as described in
sections 6.5(a), 6.5(b), and 6.5(f), respectively.

                                       52

                          Article 7. Participant Loans
                          ----------------------------

     7.1       Eligibility.  An Employee who is an Eligible Employee or an
Inactive Participant may borrow from the Plan in accordance with the terms and
conditions of this Article 7.

An Employee may have only one loan outstanding at any time. An Employee shall be
prohibited from applying for a loan in any semimonthly processing period in
which an in-service withdrawal is being processed. The preceding sentence shall
be inapplicable in the case of a withdrawal effected by a creditor of a
Participant pursuant to any insolvency proceeding initiated under federal or
state law or pursuant to any tax levy.

     7.2       Loan Amount.  An eligible Employee shall be able to borrow an
amount of at least $1,000, in increments of $100, as long as the amount of the
loan does not exceed the lesser of
(a)  fifty percent (50%) of the Employee's vested Personal Savings Account
     value, or
(b)  fifty thousand dollars ($50,000), reduced by the highest outstanding
     balance of loans to the Employee during the one year period ending on the
     day before the date on which such loan was made.

If the Employee is also covered under another qualified plan maintained by the
Company or an Affiliate, the limitation of clause (b), above, shall be applied
as though all such qualified plans with loan provisions are one plan.

The initial amount of the loan shall be limited so that repayments of principal
and interest will not exceed twenty-five percent (25%) of base compensation.
     7.3       Loan Terms.  The period of repayment for any loan shall be
arrived at by mutual agreement between the Administrative Committee and the
Employee; provided, however, that

                                       53
<PAGE>

the period of repayment must be in full-year increments and shall not extend
beyond the earlier of five years (ten years in the case of a loan meeting the
requirements of Code section 72(p)(2)(B)(ii)) or the Employee's Separation from
Service.

All loans shall bear an interest rate which shall be stated by the
Administrative Committee and shall be based on the rate being charged by Western
Federal Credit Union for loans secured by the borrower's deposit account during
the calendar month prior to the calendar month in which the loan is made. Such
interest rate shall remain in effect for the entire loan term.

All loans shall include repayment provisions requiring equal periodic payments
no less than quarterly over the term of the loan.
     7.4       Source of Loan Funds and Valuation.  The funds needed to provide
the principal amount of the loan shall come from liquidation of Investment
Funds. The amounts held in the Employee's Pretax Deferral Account, Rollover
Account, and then Employee Account shall be liquidated from such Investment Fund
or combination of Investment Funds in which the Employee has invested on a
prorata basis.

If all the funds in the Employee's Pretax Deferral Account, Rollover Account,
and Employee Account have been exhausted, and if additional funds are needed to
provide the principal amount of the loan, the Matching Account shall be
liquidated to provide additional loan funds.

Account balances liquidated from the OPC Stock Fund will be valued on the last
business day of the semimonthly processing period in which the loan is
processed. If the volume of loan requests pertaining to the OPC Stock Fund in a
given processing period necessitates selling shares on the open market, then the
loan proceeds liquidated from the OPC Stock Fund will be valued based on the
average price of all shares liquidated in the period the loan is processed.
Account

                                       54
<PAGE>

balances liquidated from all other funds will be valued at the closing value for
the semimonthly processing period in which the loan is processed.
     7.5       Loan Account.  The Administrative Committee shall establish a
loan account for the Employee, and shall credit the account with an amount equal
to the principal amount of the loan granted. Each repayment of the principal on
the loan received by the Trustee from the Employee shall reduce the balance
credited to the loan account.
     7.6       Repayments.  Repayments of the loan principal and interest will
be made through regular payroll deductions. The Employee will be required to
complete a payroll deduction authorization form for the amount of the
repayments, which shall be irrevocable throughout the term of the loan.
Employees who are paid monthly, bi-weekly/semi-monthly, and weekly will have
twelve, twenty-four and forty-eight periodic payroll deductions, respectively,
for each year of the term of the loan.

Irrespective of whether an Employee is currently contributing to the Plan,
periodic loan repayments shall first be credited to the Employee's Matching
Account, until all amounts which were liquidated for the loan principal amount
from that Account, if any, have been repaid. If an Employee is currently
contributing to the Plan, repayments shall then be credited to the Employee
Account loan balance, if any, then the Rollover Account loan balance, if any,
and then the Pretax Deferral Account loan balance, if any, in the same
proportions within each such Account as the Employee's current contributions are
being invested in the Investment Funds, until all amounts which were liquidated
for the loan principal amount from those Accounts have been repaid. If an
Employee is not currently contributing to the Plan, repayments shall then be
credited to the Employee Account loan balance, if any, then the Rollover Account
loan balance, if any, and then the Pretax Deferral Account loan balance, if any,
in the same proportions within each such Account as the latest investment
election on file for the Employee, until all amounts which were liquidated for
the loan principal amount from those Accounts have been repaid. If no investment
election is on file, all repayments to the Employee Account loan balance, if
any,

                                       55
<PAGE>

Rollover Account loan balance, if any, and Pretax Deferral Account loan balance,
if any, will be made to the Fixed Income Fund, until all amounts which were
liquidated for the loan principal amount from those Accounts have been repaid.
Any accrued interest on the loan balances in the various Accounts will be
credited to the Account to which the related principal repayment is credited.

If an Employee's total compensation will not equal the amount of the required
loan repayment for a period not to exceed three months, loan repayment payroll
deductions shall be suspended. When the Employee's total compensation once again
equals or exceeds the required loan repayment, payroll deductions shall be
reactivated in the first payroll period coincident with or next following the
increase of total compensation. When the repayments are reactivated, if the
number of payroll periods remaining are not sufficient to cover the outstanding
loan balance at the end of the maximum loan term, the loan payment shall be
reamortized or otherwise adjusted.

The Employee may make a prepayment of the entire outstanding principal loan
balance at any time after the end of the month in which the loan application is
processed, provided that this limitation shall be inapplicable to an Employee
who has Separated from Service. Any prepayments shall be credited first to the
Matching Account until all amounts which were liquidated for the loan principal
amount, if any, from that Account have been repaid. Any remaining prepayments
shall then be credited to the remaining Employee Account loan balance, if any,
then the remaining Rollover Account loan balance, if any, and then the remaining
Pretax Deferral Account loan balance, if any, in the same proportions within
each such Account as the Employee's current contributions are being invested in
the Funds, until all amounts which were liquidated for the loan principal amount
from those Accounts have been repaid. If the Employee is not currently
contributing to the Plan, all prepayments will then be credited to the Employee
Account loan balance, if any, then the Rollover Account loan balance, if any,
and then the remaining Pretax Deferral Account loan balance, if any, in the same
proportions within each such

                                       56
<PAGE>

Account as the latest investment election on file for the Employee, until all
amounts which were liquidated for the loan principal amount from those Accounts
have been repaid. If no investment election is on file, all prepayments will
then be credited to the outstanding loan balances of the Employee Account, if
any, then the Rollover Account, if any, and then the remaining Pretax Deferral
Account, if any, and in each such Account to the Fixed Income Fund. Any accrued
interest on the loan balances in the various Accounts will be credited to the
Account to which the related principal payment is credited. Notwithstanding the
loan prepayment provisions described above, an Employee whose outstanding loan
balance is considered delinquent as described in section 7.9 shall be prohibited
from making a prepayment of his outstanding principal loan balance.
     7.7       Leave of Absence.  An Employee who is on an approved, unpaid
leave of absence for a period not to exceed three months, shall have his
repayment payroll deduction suspended for the duration of the leave. When the
Employee returns to pay status, the payroll deductions will be reactivated, as
described in the third paragraph of section 7.6, and payments retroactive to the
date of commencement of the leave of absence will be required.

An Employee who is on an approved, unpaid leave of absence for a period greater
than three months, but not to exceed twelve months shall have his loan
reamortized (for a period not exceeding five years from the original loan date)
when he returns to pay status. The payroll deductions shall be increased upon
the reamortization, and the Employee shall be required to complete a new payroll
deduction authorization form for the new amount.

When an Employee incurs a Separation from Service pursuant to section 2.1(dd),
any outstanding loan balance is treated pursuant to the terms of section 7.8.
     7.8       Separation from Service.  When an Employee incurs a Separation
from Service, the outstanding loan balance shall be due and payable as of the
last day of the month in which the Separation from Service occurs. If the loan
has not exceeded the maximum loan term, the

                                       57
<PAGE>

Employee or the Employee's Beneficiary will have a period of two months from the
last day of the month in which the Separation from Service occurred, in which to
repay the outstanding loan balance in full. If the Employee or the Employee's
Beneficiary does not pay the outstanding loan balance in full within the
two-month period, or the maximum loan term has been exceeded, any outstanding
loan balance shall be treated as a distribution.
     7.9       Delinquent Payments.  A loan shall be considered delinquent if
     (a)       the  Employee, not covered pursuant to the third paragraph of
               section 7.6, sections 7.7 or 7.8, fails to make a regularly
               scheduled repayment,
     (b)       the Employee's total compensation is insufficient to make the
               authorized loan repayment payroll deduction for a period
               exceeding three months, while he is in active pay status,
     (c)       the authorized loan repayment payroll deductions are reduced or
               suspended for any reason, or
     (d)       the Employee is declared bankrupt, and unable to make subsequent
               repayments.

When an Employee's loan is considered delinquent, the outstanding principal loan
balance shall be processed as a deemed distribution, within the meaning of
proposed Treasury Regulation section 1.72(p)-1, following written notification
to the Employee. The deemed distribution shall be immediately taxable to the
Employee except to the extent that the deemed distribution represents a
nontaxable return of After-Tax Contributions from his Employee Account.

The taxable portion of the deemed distribution shall remain outstanding under
the Employee's Savings Account until the Employee incurs a Separation from
Service or, if earlier, the Employee becomes Disabled or dies. This amount shall
be treated as a nontaxable distribution when the Employee's Savings Account is
otherwise distributed.

                                       58
<PAGE>

The principal loan balance that was processed as a deemed distribution may not
subsequently be repaid to the Plan.
     7.10      Discontinuance.  The foregoing sections of this Article 7
notwithstanding, the Administrative Committee reserves the right to stop
granting loans to Employees at any time.

                         Article 8. Investment Elections
                         -------------------------------

     8.1       Investment of Contributions.  All Pretax Deferrals, After-Tax
Contributions, Adjustment Contributions, rollovers, and loan repayments (both
principal and interest) made by and on behalf of a Participant each Plan Year
and amounts merged into the Plan pursuant to section 9.10 shall be invested as
the Participant shall designate in any of the various Investment Funds in
increments of 5 percent of the aggregate amount of such contributions, provided,
however, that contribution elections made in 25% increments which were in effect
on May 31, 1990 shall remain in effect until revoked by the Participant, and
provided further that elections in effect on May 31, 1990 by Participants to
have contributions invested in the Active Bond Fund (as that Investment Fund was
then defined) shall, effective as of June 1, 1990, be considered to be elections
to have contributions invested in the Fixed Income Fund. All Matching
Contributions allocated to the Account of a Participant shall be invested in the
OPC Stock Fund. Each Participant may make the designation described above by
making an election in accordance with procedures established by the
Administrative Committee upon becoming a Participant, and may change such
election at any time thereafter by making another election in accordance with
procedures established by the Administrative Committee. In the event that a
Participant fails to designate the Investment Fund in which his Pretax
Deferrals, After-Tax Contributions, Adjustment Contributions, rollover
contributions, or amounts merged into the Plan pursuant to section 9.10 are to
be invested, such amounts shall be invested in the Fixed Income Fund. Any such
election made upon initial enrollment or upon a resumption or change in the
amount of Pretax Deferrals, After-Tax Contributions and Adjustment Contributions
shall take effect as of the first day of the month of receipt thereof by the
Administrative Committee. Elections hereunder may be made only once in any
semimonthly processing period.
     8.2       Transfers of Existing Balances.  Participants, Inactive
Participants and Alternate Payees may elect to transfer, in accordance with
procedures established by the Administrative Committee, amounts allocated to
their accounts as described herein.

                                       60
<PAGE>

Each Participant, Inactive Participant, and Alternate Payee may elect not more
often than once in any semimonthly processing period to transfer amounts
allocated to his Pretax Deferral Account, Employee Account, and Rollover Account
from any of the various Investment Funds to the Pretax Deferral Account,
Employee Account, or Rollover Account within one or more of the same Funds, in
increments of 5 percent of the amount being transferred.

Each election made pursuant to this section 8.2 shall be effective as of the
last business day of the semimonthly processing period in which notice thereof
is received by the Administrative Committee.

Any transfer made pursuant to this section 8.2 does not affect the investment of
future employee contributions, which will be invested according to the last
election filed pursuant to section 8.1.

Nothing contained in this section 8.2 shall be construed as preventing a
Participant or Inactive Participant from having amounts allocated to his Pretax
Deferral Account, Employee Account, Matching Account, or Rollover Account in any
Investment Fund transferred to one or more other Investment Funds for the
purpose of facilitating an asset transfer to the trustee of a qualified
retirement plan sponsored by a purchaser or the subsidiary of a purchaser as a
result of a transaction involving the sale by the Company or an Affiliate of
either all or substantially all of the outstanding common stock of an Affiliate
or all or substantially all of the assets of a production facility, under
circumstances where the Participant or Inactive Participant is employed by the
Affiliate or at the production facility that is the subject of the sale.

                                       61
<PAGE>

     8.3       Transfer of Assets.  In the case of transfers of existing Account
balances under section 8.2, the Administrative Committee shall direct the
Trustee to transfer moneys or other property as soon as is practical after the
end of each semimonthly processing period from the appropriate Investment Fund
to the other Investment Fund in order to carry out the aggregate transfer
transactions after the Administrative Committee has caused the necessary entries
to be made in the Participants' Accounts in the Investment Funds and has
reconciled offsetting transfer elections, in accordance with uniform rules
therefor established by the Administrative Committee.

             Article 9. Participant Accounts and Records of the Plan
             -------------------------------------------------------

     9.1       Accounts and Records.  The Participant's Pretax Deferral Account,
Matching Account, Employee Account, and Rollover Account shall be assigned a
subaccount for each Investment Fund in which the Account is invested. Each such
subaccount shall be maintained and valued separately from all other subaccounts.
The Administrative Committee shall maintain records relative to a Participant's
Accounts so that there may be determined as of any Accounting Date the current
value of his Accounts in the Trust Fund.

Each Participant shall be advised from time to time, at least once each Plan
Year, as to the value of his Personal Savings Account and the portions thereof
attributable to his Employee Account, Matching Account, Pretax Deferral Account,
and Rollover Account.
     9.2       Account Value.  As of any given date for which determination of
the value of a Participant's Account is required, such value shall equal the sum
of the value of his Pretax Deferral Account, Employee Account, Matching Account,
and Rollover Account as of the preceding Accounting Date plus any additional
contributions withheld or paid and less the amount of any withdrawals from such
Account after the Accounting Date and prior to the date of determination.

Each Participant shall be advised from time to time, at least once each Plan
Year, as to the value of his Account and the portions thereof attributable to
his various Investment Funds.
     9.3       Investment Funds.  The Trust Fund shall consist of the Investment
Funds, and each Participant who has any interest in an Investment Fund shall
have an undivided proportionate interest. The Administrative Committee shall
have the right to determine the number of Investment Funds to be maintained by
the Plan, and to increase or decrease that number from time to time as it deems
appropriate. The Investment Committee shall establish additional Investment
Funds or eliminate existing Investment Funds as directed by the

                                       63
<PAGE>

Administrative Committee. In so doing, the Investment Committee shall implement
and carry out investment objectives and policies which it shall establish and
maintain.
     9.4       Valuation Adjustments.  As of each Accounting Date, the
Administrative Committee, after crediting Participants' Accounts with
contributions made during the period ending on that date as provided herein,
shall adjust the net credit balances in the Accounts of Participants or their
Beneficiaries, in the respective Investment Funds of the Trust Fund, upward or
downward, in proportion to the Account balance of each such Participant in the
Investment Fund as of the first day of the period, so that the sum of such net
credit balances will equal the net value of each Investment Fund of the Trust
Fund as of that Accounting Date. The Administrative Committee shall determine
the net value of an Investment Fund, by subtracting from the fair market value
of assets (as reported by the Trustee) held in such Investment Fund any
expenses, withdrawals, distributions and transfers chargeable to that Investment
Fund which have been incurred but not yet paid. All determinations made by the
Trustee with respect to fair market values and determinations of the
Administrative Committee concerning net value shall be made in accordance with
generally accepted principles of trust accounting, and such determinations when
so made by the Trustee and the Administrative Committee shall be conclusive and
binding upon all persons having an interest under the Plan.
     9.5       Accounting Change.  Effective as of January 1, 1987, the unit
values of each Investment Fund, calculated as of December 31, 1986, shall be
eliminated, and subaccounts of each Participant in each Investment Fund shall be
maintained in dollar amounts thereafter. The beginning dollar balance of each
Participant's Account in each Investment Fund shall equal the dollar value of
the units held by each Account in the Investment Fund as of December 31, 1986.
Thereafter, allocations to accounts and subaccounts of a Participant shall be
made in dollars in accordance with the Participant's investment elections.
     9.6       Loan Accounts.  The value of a Participant's Loan Account shall
at all  times  equal  the  amount  of  principal outstanding on his loan.

                                       64
<PAGE>

     9.7       OPC Stock Fund Valuation.  The balance of each Participant's
Matching Account, and any portion of the Participant's Pretax Deferral Account,
Employee Account or Rollover Account invested in the OPC Stock Fund shall be
maintained in full and fractional shares of Stock.

All Stock acquired by the OPC Stock Fund, including, but not by way of
limitation, Stock contributed directly by the Employer or purchased with the
contribution made pursuant to Articles 4 and 5, Stock purchased with cash
dividends paid in respect of Stock, Stock acquired from stock dividends and
stock splits, and Stock purchased with the proceeds of the sale or exchange of
warrants, rights or dividends in kind distributed in respect of Stock, shall be
allocated to the Accounts of Participants based on Participants' Account
balances as of the beginning of the semimonthly processing period in which the
Stock is acquired.

For the purpose of valuing a Participant's Account in connection with any
withdrawal, loan or transfer under the provisions of the Plan or for the purpose
of any distribution in kind or partly in kind, shares of Stock shall be valued
as of the effective date of the withdrawal, loan, transfer or distribution based
on the closing quotation on the New York Stock Exchange on the last trading day
of the semimonthly processing period in which such withdrawal, loan, transfer or
distribution is made; provided, however, that if shares of Stock are sold in
connection with such a withdrawal, loan, transfer or distribution, the shares
sold shall be valued at the net proceeds received therefor. If the closing price
of such Stock shall not be so quoted or if so quoted shall not be available to
the Administrative Committee, a composite index price or other price which shall
be generally accepted for the establishment of fair market value shall be used
for the purpose of so valuing the Participant's Account.
     9.8       Cost Account.  The Trustee shall maintain records so that the
cost or "basis" (for tax purposes) of the Stock allocated to his Account may be
determined as of any Accounting Date. Whenever shares of Stock are allocated to
the Account of a Participant, such shares shall

                                       65
<PAGE>

be assigned a cost equal to the average cost of all shares allocated at the same
time in accordance with rules and procedures adopted for the purpose by the
Administrative Committee.
     9.9       Rollovers.  Subject to the Administrative Committee's approval,
amounts which a Participant has received or is entitled to receive from any
other employee benefit plan may, in accordance with uniform and
nondiscriminatory procedures adopted by the Administrative Committee, be
transferred by the Participant to this Plan or, alternatively, by the trustee of
the other employee benefit plan directly to this Plan, and if transferred, shall
be credited to such Participant's Rollover Account hereunder, provided the
following conditions are satisfied:
     (a)       The rollover amounts tendered to the Administrative Committee
               must have been received by or on behalf of the Participant from:
               (1)  A plan qualified under section 401(a) of the Code; or
               (2)  A conduit individual retirement account, described in
                    section 408(d)(3)(A)(ii) of the Code, to which no individual
                    retirement account contributions were made or rolled over
                    from a qualified plan.
     (b)       In the case of a distribution described in (a)(1), above, the
               amounts tendered must not include:
               (1)  Amounts contributed to a qualified plan on an after-tax
                    basis by a Participant, or
               (2)  Any other amounts not eligible for rollover treatment.
     (c)       Amounts must be received by the Administrative Committee not
               later than 60 days after the distribution was received by the
               Participant.

The Administrative Committee shall establish such procedures, and may require
such additional information from the Participant as it deems necessary or
appropriate to determine that a proposed transfer hereunder will satisfy the
above requirements. Rollover amounts shall be transmitted to the Trustee to be
invested in such Investment Funds as the Eligible Employee may

                                       66
<PAGE>

select, in accordance with such rules as are provided in Article 8, or in
accordance with other procedures approved by the Administrative Committee.
     9.10      Merger of the MidCon Corp. ESOP.  Effective May 15, 1998, the
MidCon Corp. ESOP shall be merged with and into the Plan and the entire interest
of each individual who was a participant in the MidCon Corp. ESOP as of May 15,
1998, shall be transferred to this Plan and held in a Rollover Account
established on behalf of each such individual. Such amounts shall be invested in
accordance with section 8.1. For the period prior to May 15, 1998, the terms of
the MidCon Corp. ESOP, as established November 20, 1996, shall apply.

                              Article 10. Financing
                              ---------------------

     10.1      Financing.  The Company shall maintain a Trust to finance the
benefits under the Plan, by entering into one or more Trust Agreements or
insurance contracts approved by the Company, or by causing insurance contracts
to be held under a Trust Agreement. Any Trust Agreement is designated as and
shall constitute a part of this Plan, and all rights which may accrue to any
person under this Plan shall be subject to all the terms and provisions of such
Trust Agreement. A Trustee shall be appointed by the Board of Directors and
shall have such powers as provided in the Trust Agreement. The Company may
modify any Trust Agreement or insurance contract from time to time to accomplish
the purpose of the Plan and may replace any insurance company or appoint a
successor Trustee or Trustees. By entering into such Trust Agreements or
insurance contracts, the Company shall vest in the Trustee, or in one or more
investment managers (as defined under ERISA) appointed under the terms of the
Trust Agreement from time to time by action of the Investment Committee,
responsibility for the management and control of the Trust Fund. In the event
the Investment Committee appoints any such investment manager, the Trustee shall
not be liable for the acts or omissions of the investment manager or have any
responsibility to invest or otherwise manage any portion of the Trust Fund
subject to the management and control of the investment manager. The Investment
Committee from time to time shall establish a funding policy which is consistent
with the objectives of the Plan and shall communicate it to the Trustee and each
investment manager so that they may coordinate investment policies with such
funding policy.
     10.2      Employer Contributions.  The Employer shall make such
contributions to the Trust Fund as are required by this Plan, subject to the
right of the Company to discontinue the Plan.
     10.3      OPC Stock Fund.  The OPC Stock Fund shall consist of shares of
Stock and cash or cash equivalents that are held pending investment in Stock.
Investment in such shares shall be made from time to time by a direct issue of
Stock from the Company, or by purchase from

                                       68
<PAGE>

securities dealers or by private purchase at such prices and in such amounts as
the Trustee may determine in its absolute and uncontrolled discretion. However,
no private purchase of such shares shall be made at a total cost greater than
the total cost (including brokers' fees and other expenses of purchase) of
purchasing such shares at the then prevailing price of such shares on the open
market, such prevailing price to be determined by the Trustee as nearly as
practicable based on the most recent public trading prices for the Stock. The
Trustee may match purchases and sales to satisfy investment elections,
withdrawals, loans and distributions of Participants.

Cash dividends and cash proceeds from any other distribution received on Stock
shall be invested in Stock. The Trustee in its own discretion may invest funds
awaiting investment in Stock in short-term obligations, including obligations of
the United States of America or any agency or instrumentality thereof, trust and
participation certificates, beneficial interests in any trust, and such other
short-term obligations as the Trustee deems to be appropriate for such interim
investment purposes.

The Trustee in its discretion may limit the daily volume of its purchases or
sales of Stock to safeguard interest of Participants or comply with legal or
exchange requirements. If the Trustee limits daily volume then the purchase
prices or sale proceeds, as the case may be, during the period of volume
limitations, shall be averaged, and the average per share price or sale proceeds
shall be used in determining the cost or proceeds to be applied in satisfaction
of any order of a Participant which requires the Trustee to purchase or sell
Stock during such period.

Investment elections of Company officers shall be limited, if necessary, so that
the beneficial interest in the Stock held by the Trust for their Accounts shall
not exceed, in the aggregate, 20 percent of the total value of all securities
and other assets held by the Trust, in all Investment Funds. For purposes of
this section 10.3, the term "officers" shall have the same meaning as set

                                       69
<PAGE>

forth in Regulation section 240.3-b-2 promulgated pursuant to section 3(b) of
the Securities Exchange Act of 1934.

All Stock purchased by the Trustee shall be registered in the name of the
Trustee or its nominee, and legal title to such Stock shall remain in the
Trustee until the Participant shall become entitled to distribution thereof
pursuant to this Plan.

In the event any option, right or warrant is received by the Trustee on Stock,
the Trustee shall sell the same at public or private sale and at such price and
upon such other terms as it may determine, unless the Investment Committee shall
determine that such option, right or warrant should be exercised, in which case
the Trustee shall exercise the same upon such terms and conditions as the
Investment Committee may prescribe.

The Trustee shall have the power to vote all shares of Stock held under this
Plan and may vote such shares itself or by proxy, except that the Trustee shall
vote shares of Stock credited to accounts of Participants and Alternate Payees
for which it has received directions from Participants and Alternate Payees in
accordance with such direction. The Trustee shall vote any Stock for which it
does not receive instructions from Participants or Alternate Payees in
accordance with directions from the Administrative Committee.
     10.4      Non-Reversion.  Anything in this Plan to the contrary
notwithstanding, it shall be impossible at any time for the contributions of the
Employer or any part of the Trust Fund to revert to the Company or an Affiliate
or to be used for or diverted to any purpose other than the exclusive benefit of
Participants or their Beneficiaries, except that:
     (a)       If a contribution or portion thereof is made by the Employer by a
               mistake of fact, upon written request to the Administrative
               Committee, such contribution or such portion and any increment
               thereon shall be returned to the Employer within one year after
               the date of payment; and

                                       70
<PAGE>

     (b)       In the event that a deduction for any contributions made by the
               Employer is disallowed by the Internal Revenue Service in any
               Plan Year, then that portion of the Employer contribution that is
               not deductible shall be returned to the Employer within one year
               from the date of receipt of notice by the Internal Revenue
               Service of the disallowance of the deduction.
     10.5      Direct Transfer of Assets from Plans of Acquired Entities.  The
Trust Agreement shall permit the direct receipt of assets which are transferred
directly to the Trust Fund from the trustees of qualified retirement plans
sponsored, at the time of the applicable transaction, by entities which are the
subject of purchase transactions made by the Company or an Affiliate.

any agent to execute or deliver any instrument or instruments on their behalf,
and may employ such counsel, auditors, and other specialists and such clerical,
medical, actuarial, and other services as they may require in carrying out the
provisions of the Plan.
     11.3      Compensation and Expenses.  The members of the Investment
Committee and Administrative Committee who are Employees shall serve without
compensation for services as a member of such Committee. Any member of a
Committee may receive reimbursement by the Company of expenses properly and
actually incurred. All expenses of a Committee shall be paid by the Company.
Such expenses may include any expenses incident to the functioning of a

                                       72
<PAGE>

Committee, including, but not limited to, fees of the Plan's accountants,

     11.4      Manner of Action.  A majority of the members of the Investment
Committee and Administrative Committee at the time in office shall constitute a

of those present at any such meeting. Upon obtaining the written consent of a
majority of the members at the time in office, action of a Committee may be
taken otherwise than at a meeting.
     11.5      Subcommittees.  Each of the Investment Committee and
Administrative Committee may appoint one or more subcommittees and delegate such
of its power and duties as it deems desirable to any such subcommittee, in which
case every reference herein made to such Committee shall be deemed to mean or
include the subcommittees as to matters within their jurisdiction. The members
of any such subcommittee shall consist of such officers or other Employees of
the Company and such other persons as such Committee may appoint.
     11.6      Other Agents.  Each Committee may also appoint one or more
persons or agents to aid it in carrying out its duties as fiduciary, and
delegate such of its powers and duties as it deems desirable to such person or
agents.
     11.7      Records.  All resolutions, proceedings, acts, and determinations
of each Committee shall be recorded by the Secretary thereof or under his
supervision, and all such records, together with such documents and instruments
as may be necessary for the administration of the Plan, shall be preserved in
the custody of the Secretary.
     11.8      Rules.  Subject to the limitations contained in the Plan, each

Notwithstanding the foregoing, the administrative committee of the MidCon Corp.
ESOP, as appointed as set forth in section 9.10 thereof, shall continue to have
the authority to construe and interpret the MidCon Corp. ESOP and the provisions
of the Plan relating to amounts transferred to the Plan pursuant to section 9.10
hereof, and to supply all omissions from, correct deficiencies in, and resolve
ambiguities in such language and related trusts; to decide all questions
(including without limitation questions of fact) of eligibility and determine
the amount, manner, and time of payment of any benefits under the MidCon Corp.
ESOP; to determine the rights of any person to an allocation and the amount
thereof thereunder; and to continue to administer the Benefits Claims Procedures
under section 9.18 thereof.
     11.10     Investment Responsibilities.  The Investment Committee shall have
the authority and responsibility to direct the Trustee with respect to the
investment and management of the Trust Fund, and to establish a funding policy
and method consistent with the objectives of the Plan and the requirements of
ERISA. Except as otherwise provided in ERISA, the Investment Committee may
delegate such authority and responsibility to direct the Trustee to any person
who acknowledges in writing that it is a fiduciary with respect to the Plan and
who provides the Investment Committee with a written affirmation that it is
qualified to act as an investment manager within the meaning of ERISA. If the
Investment Committee delegates to an investment manager the authority and
responsibility to so direct the Trustee, such investment manager, and not the
Investment Committee or the Trustee, shall have sole responsibility for the
investment and management of so much of the Trust Fund as has been entrusted to
his management and control, and, except to the extent otherwise required by
ERISA, such delegation shall relieve the Investment Committee and the members
thereof of all duties and responsibilities with respect to the authority and
responsibility so delegated.

The Investment Committee may relinquish to the Trustee the Investment
Committee's power to direct the Trustee with respect to the investment and
management of the Trust Fund. In the event the Investment Committee so
relinquishes said power to the Trustee and the Trustee accepts such

                                       75
<PAGE>

responsibility in writing, the Trustee shall have sole and exclusive power and
responsibility with respect to the investment and management of the Trust Fund.
The Investment Committee may regain the power so relinquished by appropriate
Investment Committee action and notice to the Trustee.
     11.11     Committees' Decisions Conclusive.  The Administrative Committee
and the Investment Committee shall exercise their powers hereunder in a uniform
and nondiscriminatory manner. Any and all disputes with respect to the Plan
which may arise involving Participants, or their Beneficiaries shall be referred
to the Administrative Committee and its decision shall be final, conclusive, and
binding. Furthermore, if any question arises as to the meaning, interpretation,
or application of any provision hereof, the decision of the Administrative
Committee with respect thereto shall be final.
     11.12     Indemnity.  To the extent permitted by the Company's bylaws and
applicable law, the Company shall indemnify each member of the Administrative
Committee and the Investment Committee (which, for purposes of this section,
includes any Employee to whom the Administrative Committee or the Investment
Committee has delegated fiduciary or other duties) against any and all claims,
losses, damages, expenses, including counsel fees, incurred by the member and
any liability, including any amounts paid in settlement with the Company's
approval, arising from the member's or the Company's action or failure to act,
except when the same is judicially determined to be attributable to the gross
negligence or willful misconduct of such member. The right of indemnity
described in the preceding sentence shall be conditioned upon the timely receipt
of notice by the Company of any claim asserted against the member, which notice,
in the event of a lawsuit shall be given within ten days after receipt by the
member of the complaint.
     11.13     Fiduciaries.  The fiduciaries named in this Article shall have
only those specific powers, duties, responsibilities, and obligations as are
specifically given them under this Plan or the Trust. The Employer shall have
the sole responsibility for making the contributions specified in Articles 4 and
5, and the Company shall have the sole authority to appoint and remove the

                                       76
<PAGE>

Trustee and to amend or terminate, in whole or in part, this Plan or the Trust.
The Administrative Committee shall have the sole responsibility for the
administration of this Plan, which responsibility is specifically described in
this Plan and the Trust Agreement. The officers and Employees of the Company
shall have the responsibility of implementing the Plan and carrying out its
provisions as the Administrative Committee shall direct. The Investment
Committee, the Trustee, and any investment manager shall have the sole
responsibility for the administration of the Trust and the management of the
assets held under the Trust, to the extent provided in the Trust Agreement. A
fiduciary may rely upon any direction, information, or action of another
fiduciary as being proper under this Plan or the Trust, and is not required
under this Plan or the Trust to inquire into the propriety of any such
direction, information, or action. It is intended under this Plan and the Trust
that each fiduciary shall be responsible for the proper exercise of his or its
own powers, duties, responsibilities, and obligations under this Plan and the
Trust and shall not be responsible for any act or failure to act of another
fiduciary. No fiduciary guarantees the Trust Fund in any manner against
investment loss or depreciation in asset value. Any party may serve in more than
one fiduciary capacity with respect to the Plan or Trust.
     11.14     Notice of Address.  Each person entitled to benefits from the
Plan must file with the Administrative Committee or its agent, in writing, his
post office address and each change of post office address. Any communication,
statement, or notice addressed to such a person at his latest reported post
office address will be binding upon him for all purposes of the Plan, and
neither the Administrative Committee nor the Company or any Trustee shall be
obliged to search for or ascertain his whereabouts.
     11.15     Data.  All persons entitled to benefits from the Plan must
furnish to the Company such documents, evidence, or information, including
information concerning marital status, as the Company considers necessary or
desirable for the purpose of administering the Plan; and it shall be a condition
of the Plan that each such person must furnish such information and sign such
documents as the Company may require before any benefits become payable from the
Plan. The Administrative Committee shall be entitled to distribute benefits to a
non-spouse beneficiary

                                       77
<PAGE>

in reliance upon the signed statement of the Participant that he is unmarried
without any further liability to a spouse if such statement is false.
     11.16     Benefit Claims Procedures.  All applications for benefits under
the Plan shall be submitted to: Occidental Petroleum Corporation, Attention:
Pension and Retirement Plan Administrative Committee, 10889 Wilshire Blvd., Los
Angeles, CA 90024. Applications for benefits must be in writing on the forms
prescribed by the Administrative Committee and must be signed by the
Participant, or in the case of a death benefit, by the Beneficiary or legal
representative of the deceased Participant. Each application shall be acted upon
and approved or disapproved within 60 days following its receipt by the
Administrative Committee. If any application for a benefit is denied, in whole
or in part, the Administrative Committee shall notify the applicant in writing
of such denial and of his right to a review by the Administrative Committee and
shall set forth in a manner calculated to be understood by the applicant,
specific reasons for such denial, specific references to pertinent Plan
provisions on which the denial is based, a description of any additional
material or information necessary for the applicant to perfect his application,
an explanation of why such material or information is necessary, and an
explanation of the Plan's review procedure.

Any person, or his duly authorized representative, whose application for
benefits is denied in whole or in part, may appeal from such denial to the
Administrative Committee for a review of the decision by submitting to the
Administrative Committee within 60 days after receiving notice of the denial a
written statement:
     (a)       requesting a review of his application for benefits by the
               Administrative Committee;
     (b)       setting forth all of the ground upon which his request for review
               is based and any facts in support thereof; and
     (c)       setting forth any issues or comments which the applicant deems
               relevant to his application.

                                       78
<PAGE>

The Administrative Committee shall act upon each such application within 60 days
after the later of receipt of the applicant's request for review by the
Administrative Committee or receipt of any additional materials reasonably
requested by the Administrative Committee from such applicant.

The Administrative Committee shall make a full and fair review of each such
application and any written materials submitted by the applicant or the Employer
in connection therewith and may require the Employer or the applicant to submit
within 30 days of written notice by the Administrative Committee therefor, such
additional facts, documents, or other evidence as the Administrative Committee,
in its sole discretion, deems necessary or advisable in making such a review. On
the basis of its review, the Administrative Committee shall make an independent
determination of the applicant's eligibility for benefits under the Plan. The
decision of the Administrative Committee on any application for benefits shall
be final and conclusive upon all persons if supported by substantial evidence in
the record.

If the Administrative Committee denies an application in whole or in part, the
Administrative Committee shall give written notice of its decision to the
applicant setting forth in a manner calculated to be understood by the applicant
the specific reasons for such denial and specific references to the pertinent
Plan provisions on which the Administrative Committee decision was based.
     11.17     Member's Own Participation.  No member of the Administrative
Committee or the Investment Committee may act, vote or otherwise influence a
decision of the committee on which he serves specifically relating to his own
participation under the Plan.

                      Article 12. Amendment and Termination
                      -------------------------------------

     12.1      Amendment and Termination.  The Company expects the Plan to be
permanent and to continue indefinitely; however, this Plan is purely voluntary
on the part of the Company, and each Employer, and the Company must necessarily
and does hereby reserve the right to amend, modify, or terminate the Plan at any
time by action of its Board of Directors. The Administrative Committee in its
discretion may amend the Plan if it finds that such amendment does not
significantly increase or decrease benefits or costs. No amendment of the Plan
shall cause any part of the Trust Fund to be used for, or diverted to, purposes
other than for the exclusive benefit of the Participants or their Beneficiaries
covered by the Plan, or increase the duties and responsibilities of the Trustee
without its consent, or decrease the Account balance of a Participant or
Beneficiary.
     12.2      Distribution on Termination.  Upon termination of the Plan in
whole or in part, or upon complete discontinuance of contributions to the Plan
by the Company, the value of the proportionate interest in the Trust Fund of
each Participant affected by such termination shall be determined by the
Administrative Committee as of the date of such termination or discontinuance.
The Accounts of such Participants shall be fully vested and nonforfeitable, and
thereafter distribution shall be made to such Participants as directed by the
Administrative Committee.

Upon the partial termination of the Plan, the Board of Directors may in its sole
discretion determine the timing of a distribution of the balance of the affected
Participants' Accounts.
     12.3      Successors.  In case of the merger, consolidation, liquidation,
dissolution or reorganization of an Employer, or the sale by an Employer of all
or substantially all of its assets, provision may be made by written agreement
between the Company and any successor corporation acquiring or receiving a
substantial part of the Employer's assets, whereby the Plan and the Trust will
be continued by the successor. If the Plan is to be continued by the successor,

                                       80
<PAGE>

then effective as of the date of the reorganization or transfer, the successor
corporation shall be substituted for the Employer under the Plan and the Trust
Agreement. The substitution of a successor corporation for an Employer will not
in any way be considered a termination of the Plan.
     12.4      Plan Merger or Transfer.  This Plan shall not merge or
consolidate with, or transfer assets and liabilities to, or accept a transfer
from, any other employee benefit plan unless each Participant in this Plan will
(if the Plan had then terminated) receive a benefit immediately after the
merger, consolidation, or transfer which is not less than the benefit the
Participant would have been entitled to receive immediately before the merger,
consolidation, or transfer of assets (if this Plan had then terminated). Subject
to these limitations, the Plan may transfer assets and liabilities to, or accept
a transfer of assets and liabilities from, any other employee benefit plan which
is qualified under Code section 401(a) where such a transfer has been authorized
by agreement between the Employer and the sponsor of the other employee benefit
plan and is not prohibited by law.
     12.5      Participating Affiliates.  The Board of Directors or the
Administrative Committee may designate any Affiliate as an Employer under this
Plan. The Affiliate shall become an Employer and a party to this Plan and the
Trust upon acceptance of such designation. Any Affiliate may withdraw from the
Plan and Trust, and end its status as an Employer hereunder, by communicating to
the Administrative Committee its desire to withdraw. Upon withdrawal, the Plan
shall be considered terminated as to Employees of such Affiliate.

                        Article 13. Top-Heavy Provisions
                        --------------------------------

     13.1      Application of Top-Heavy Provisions.  If in any Plan Year after
1983 (i) the sum of the Personal Savings Account balances of Participants who
are "Key Employees" for such Plan Year exceeds 60 percent of the sum of Personal
Savings Account balances of all Employees (and former Employees or Beneficiaries
described in section 13.4), or (ii) the Plan is part of a top-heavy group, then
the following provisions under this Article shall apply for such Plan Year.

The date for determining the applicability of this Article, ("determination
date") is:
     (a)       For the first Plan Year, the last day of the Plan Year; and
     (b)       For any other Plan Year, the last day of the preceding Plan Year.
     13.2      Key Employees.  For purposes of this Article, the term "Key
Employee" means any Employee or former Employee (or his Beneficiary) who at any
time during a Plan Year or any of the four preceding Plan Years is:
     (a)       An officer of the Company or its Affiliates who receives Taxable
               Compensation of more than $60,000 (or, if greater, one half of
               the dollar limitation in effect under Code section 415(b)(1)(A))
               in the Plan Year; provided no more than the lesser of (i) 50
               Employees, or (ii) the greater of three Employees or 10 percent
               of all Employees are to be treated as officers;
     (b)       One of the ten Employees owning the largest interests in excess
               of one-half percent of the Company or an Affiliate if such
               Employee receives Taxable Compensation during the Plan Year that
               exceeds $30,000 (or, if greater, the dollar limitation in effect
               under Code section 415(c)(1)(A));
     (c)       A 5 percent owner of the Company or an Affiliate; or
     (d)       A 1 percent owner of the Company or an Affiliate who receives
               Taxable Compensation of more than $150,000 for the Plan Year.

                                       82
<PAGE>

An Employee is considered to own more than a 5 percent interest if the Employee
owns at least 5 percent of the Company's outstanding Stock or Stock possessing
at least 5 percent of the total combined voting power of all of the Company and
Affiliates' Stock. An Employee is also treated as owning Stock owned by certain
members of the Employee's family as provided in section 318 of the Code.
The same rules apply to determine whether an Employee is a 1 percent owner.

If an Employee ceases to be a Key Employee, such Employee's Personal Savings
Account balance shall be disregarded under the top-heavy plan computation for
any Plan Year following the last Plan Year for which he was treated as a Key
Employee.
     13.3      Top-Heavy Group.  For purposes of determining whether the Plan is
part of a top-heavy group as described in section 13.1, the following rules
shall apply:
     (a)       Aggregation Group. All plans maintained by the Company or an
               Affiliate are aggregated to determine whether the plans, as a
               group, are top-heavy. The aggregation group shall include any
               plan which covers a Key Employee and any other plan which enables
               a plan covering a Key Employee to meet the requirements of
               section 401(a)(4) or 410 of the Code.
     (b)       Top-Heavy Group. An aggregation group is a top-heavy group if, as
               of the determination date, (1) the sum of the account balances of
               Key Employees under all defined contribution plans included in
               the group exceeds 60 percent of the account balances of all
               participants under all such plans in the group, or (2) the
               present value of the accumulated accrued benefits for Key
               Employees under all defined benefit plans in the group exceeds 60
               percent of the present value of the accumulated accrued benefits
               for all participants under all such plans in the group.

In any Plan Year, in testing for top-heaviness under section 13.1, the Company
may in its discretion expand the aggregation group to take into account any
other plan maintained by it or

                                       83
<PAGE>

an Affiliate, so long as such expanded aggregation group continues to meet the
requirements of sections 401(a)(4) and 410 of the Code.
     13.4      Additional Rules.  In determining the present value of the
accumulated accrued benefits under a defined benefit plan and the sum of the
account balances under a defined contribution plan, Company contributions and
Employee contributions (other than deductible employee contributions) as of the
determination date for the Plan Year shall be taken into account. The present
value of accrued benefits shall, for purposes of this Article, be calculated by
using factors derived from the UP-84 mortality table, set back one year, and a 5
percent interest rate. The present value of the accrued benefit in a defined
benefit plan or the account balance in a defined contribution plan will include
any amount distributed to a Participant within the five year period ending on
the determination date, but shall not include a rollover initiated by the
Employee and made after December 31, 1983. Accrued benefits or account balances
of Employees who have not performed services for the Employer during the five
Plan Years ending on the determination date shall not be taken into account.
Additionally, for the purpose of determining the present value of the
accumulated accrued benefits under a defined benefit plan and the sum of the
account balances under a defined contribution plan, the rules set forth in Code
sections 416(g)(3) and (4) will be taken into account.
     13.5      Combined Limit on Contributions and Benefits for Key Employees.
If the Plan is determined to be top-heavy in any Plan Year under the provisions
of section 13.1 or 13.3, then the combined limit on benefits and contributions
under section 415(e) of the Code for any Key Employee who participates in both a
defined benefit plan and a defined contribution plan which are included in a
top-heavy group as provided in section 13.3 above shall be the lesser of 1.0 (as
applied to the dollar limit) or 1.4 (as applied to the limit based upon
compensation).
     13.6      Minimum Contributions.  If this Plan is determined to be
top-heavy in any Plan Year under the provisions of section 13.1 or 13.3, then
contributions shall be made under the Retirement Plan on behalf of each non-Key
Employee who is a Participant hereunder in an amount not less than three percent
of the Participant's Taxable Compensation for each year.

                      Article 14. Miscellaneous Provisions
                      ------------------------------------

     14.1      Employment Rights.  Nothing contained in this Plan or any
modification of the same or act done in pursuance hereof shall be construed as
giving any person any legal or equitable right against the Employer, the
Trustee, or the Trust Fund, unless specifically provided herein, or as giving
any person a right to be retained in the employ of the Employer. All
Participants shall remain subject to assignment, reassignment, promotion,
transfer, layoff, reduction, suspension, and discharge to the same extent as if
this Plan had never been established.
     14.2      No Examination or Accounting.  Neither this Plan nor any action
taken thereunder shall be construed as giving any person the right to an
accounting or to examine the books or affairs of the Company or Employer.
     14.3      Investment Risk.  The Participants and their Beneficiaries shall
assume all risks in connection with any decrease in the value of any assets or
funds which may be invested or reinvested in the Trust which supports this Plan.
     14.4      Non-Alienation.  No Benefit payable at any time under the Plan
shall be subject to the debts or liabilities of a Participant or his
Beneficiary. Any attempt to alienate, sell, transfer, assign, pledge, or
otherwise encumber any such benefit, whether presently or thereafter payable,
shall be void. Except as otherwise provided by law, no benefit under the Plan
shall be subject in any manner to attachment, garnishment, or encumbrance of any
kind, provided, however, that judicial orders for purposes of enforcing family
support obligations or pertaining to domestic relations (which orders do not
alter the amount of the benefit) may, at the discretion of the Administrative
Committee, be honored by the Plan. The Administrative Committee shall establish
appropriate procedures for reviewing court orders pertaining to domestic
relations and child support and for notifying Participants of the receipt of
such orders.
     14.5      Incompetency.  Every person receiving or claiming benefits under
the Plan shall be conclusively presumed to be mentally competent and of age
until the date on which the

                                       85
<PAGE>

Administrative Committee receives a written notice, in a form and manner
acceptable to the Administrative Committee, that such person is incompetent or a
minor, for whom a guardian or other person legally vested with the care of his
Person or estate has been appointed; provided, however, that if the
Administrative Committee shall find that any person to whom a benefit is payable
under the Plan is unable to care for his affairs because of incompetency, or is
a minor, any payment due (unless a prior claim therefor shall have been made by
a duly appointed legal representative) may be paid to the spouse, a child, a
parent, or a brother or sister, or to any person or institution deemed by the
Administrative Committee to have incurred expense for such person otherwise
entitled to payment. To the extent permitted by law, any such payment so made
shall be a complete discharge of liability therefor under the Plan.

In the event a guardian of the estate of any person receiving or claiming
benefits under the Plan shall be appointed by a court of competent jurisdiction,
benefit payments may be made to such guardian, provided that proper proof of
appointment and continuing qualification is furnished in a form and manner
acceptable to the Administrative Committee. To the extent permitted by law, any
such payment so made shall be a complete discharge of liability therefor under
the Plan.
     14.6      Severability.  In the event any provision of this Plan shall be
held illegal or invalid for any reason, such illegality or invalidity shall not
affect the remaining parts of this Plan, and it shall be construed and enforced
as if such illegal or invalid provision had never been inserted herein.
     14.7      Counterparts.  This Plan may be executed in any number of
counterparts, each of which shall be deemed to be an original. All the
counterparts shall constitute but one and the same instrument and may be
sufficiently evidenced by any one counterpart.
     14.8      Service of Legal Process.  The members of the Administrative
Committee and the Secretary of the Company are hereby designated agent of the
Plan for the purpose of receiving service of summons, subpoena, or other legal
process.

                                       86
<PAGE>

     14.9      Headings of Articles and Sections.  The headings of sections and
subsections are included solely for convenience of reference, and if there is
any conflict between such headings and the text of the plan, the text shall
control.
     14.10     Applicable Law.  The Plan and all rights hereunder shall be
governed, construed, and administered in accordance with the laws of the State
of California with the exception that any Trust Agreement which may constitute a
part of the Plan shall be construed and enforced in all respects under and by
the laws of the State in which the Trustee thereunder is located.
     14.11     Unclaimed Benefits.  In the event that the Administrative
Committee, after having made a diligent search, is unable to locate a
Participant, Beneficiary, or Alternate Payee who is entitled to benefits under
this Plan, such benefits shall be reallocated to the accounts of other
Participants in accordance with section 9.4. In the event that the Participant,
Beneficiary, or Alternate Payee whose account is subject to such reallocation
subsequently asserts a valid claim for his benefits, his account will be
restored in the manner described in section 6.3(a).
     14.12     Qualified Military Service.  Notwithstanding any provision of
this Plan to the contrary, contributions, benefits and Service credit with
respect to qualified military service will be provided in accordance with
section 414(u) of the Code.
