                     FIFTEENTH AMENDMENT TO THE PENSION PLAN
                    FOR EMPLOYEES OF THE COASTAL CORPORATION

         THIS AMENDMENT is made the 29th day of September, 2000, by The Coastal
Corporation, a Delaware corporation (hereinafter referred to as the "Company").

                                   WITNESSETH:

         WHEREAS, the Pension Plan for Employees of The Coastal Corporation was
restated as of January 1, 1989, and has since been amended (such plan, as
restated and amended, is hereinafter referred to as the "Plan");

         WHEREAS, the Company wishes to amend the definition of "leased
employee" to clarify that the employee will receive credit for purposes of
vesting for the twelve-month period of service prior to achieving the status of
"leased employee;" and

         WHEREAS, the Company wishes to amend the Plan to provide for an offset
against benefits in the event of a criminal conviction under ERISA as permitted
by statute; and

         WHEREAS, the Company wishes to amend the Plan to clarify the provisions
with respect to the payment of benefits under qualified domestic relations
orders; and

         WHEREAS, the Company wishes to amend the Plan to increase the benefit
to be paid for years of service after 1998 in the Seventh Supplement - Coal
Supplement; and

         WHEREAS, the Company wishes to amend the Plan to add an Eleventh
Supplement, "Great Lakes Early Retirement Supplement," to provide for an early
retirement incentive program for individuals who were employees of Great Lakes
Gas Transmission Company on March 31, 2000;

         NOW, THEREFORE, the Plan is amended as follows:

1.       The first paragraph of Subsection 1.10(g) is amended to read in its
         entirety as follows:

                  "(g) A person who is not an employee of the Company, a
         Subsidiary or a Related Employer and who performs services for the
         Company, Subsidiary or Related Employer pursuant to an agreement
         between the Company, a Subsidiary or a Related Employer and a leasing
         organization shall be considered a "leased employee" after such person
         performs such services for a twelve-month period and the services are
         performed under the primary direction or control of the Company,
         Subsidiary or a Related Employer. A person who is considered a leased
         employee of the Company, a Subsidiary or a Related Employer shall not
         be considered an Employee for purposes of the Plan. If a leased
         employee subsequently becomes an Employee and thereafter participates
         in the Plan, he shall receive credit for vesting under Section 5.4 for
         the twelve-month period prior to his becoming a leased employee and his
         period of employment as a leased employee, except to the extent that
         Section 414(n)(5) of the Code was satisfied with respect to such
         Employee while he was a leased employee."

2.       The first sentence of Section 5.7(g) is amended to read in its
         entirety as follows:

                  "Any Participant whose payments of Retirement Income are
         suspended pursuant to paragraph (d) of this Section, shall be notified
         (by personal delivery or first class mail) during the first calendar
         month in which payments are withheld, that his Retirement Income is
         suspended."

3.       Section 12.7 is amended to read in its entirety as follows:

         12.7     Interest Nontransferable.
                  ------------------------

                  "(a) Except as provided in this Section, no interest of any
         person or entity in, or right to receive distributions from, the Trust
         Fund shall be subject in any manner to sale, transfer, assignment,
         pledge, attachment, garnishment, or other alienation or encumbrance of
         any kind; nor may such interest or right to receive distributions be
         taken, either voluntarily or involuntarily, for the satisfaction of the
         debts of, or other obligations or claims against, such person or
         entity, including claims for alimony, support, separate maintenance and
         claims in bankruptcy proceedings.

                  (b) Notwithstanding the limitations of the provisions of
         subsection 12.7(a), a Participant's benefit under this Plan may be
         offset for an amount that the Participant is ordered or required to pay
         this Plan if the order or requirement to pay arises (i) under a
         judgment of conviction of crime involving this Plan, (ii) under a civil
         judgment (including a consent order or decree) entered by a court in an
         action brought in connection with a violation (or alleged violation) of
         the ERISA fiduciary responsibility provisions, or (iii) pursuant to a
         settlement agreement between the Internal Revenue Service or the
         Pension Benefit Guaranty Corporation and the Participant in connection
         with a violation (or alleged violation) of the ERISA fiduciary
         responsibility provisions by a fiduciary or other person. The judgment,
         order, decree or settlement agreement must expressly provide for the
         offset of all or part of the amount ordered or required to be paid to
         this Plan against the Participant's benefit.

                  (c) Notwithstanding the preceding provisions of this Section,
         all or any part of the Accrued Benefit of a Participant shall be
         subject to and payable in accordance with the applicable requirements
         of any Qualified Domestic Relations Order, as that term is defined in
         Section 414(p) of the Code, and the Administrator shall direct the
         Trustee to provide for payment in accordance with such Order and
         Section and any regulations promulgated under such Section. All such
         payments pursuant to Qualified Domestic Relations Orders shall be
         subject to reasonable rules and regulations promulgated by the
         Administrator; provided that such rules and regulations are consistent
         with Section 414(p) of the Code. If prior to the commencement of
         payment to a Participant of his Retirement Income, any amount of his
         Accrued Benefit is paid to an alternate payee or payees pursuant to a
         Qualified Domestic Relations Order, the amount of his Accrued Benefit
         shall be reduced by the Actuarial Equivalent of any such payment.

                  Notwithstanding any Plan provision to the contrary, an
         alternate payee pursuant to a Qualified Domestic Relations Order shall
         not receive any portion of an increase in benefits due to early
         retirement to which the Participant is or may be entitled. Any benefit
         received by such an alternate payee shall be Actuarial Equivalent of
         the portion of the benefit to which such alternate payee is entitled at
         Normal Retirement Age of the Participant reduced on an actuarial basis
         to reflect the payment at an earlier date should such alternate payee
         elect to receive benefits before the Normal Retirement Date of the
         Participant.

                  For purposes of this Section, if the Participant's benefit is
         to be paid in the form of a survivor annuity under the Plan, then (i)
         the Spouse of such Participant must provide a consent in writing,
         witnessed by a notary public or Plan representative), unless the
         Participant establishes to the satisfaction of the Administrator that
         such consent may not be obtained because there is no Spouse, the Spouse
         cannot be located, or because of such other circumstances as the
         Secretary of the Treasury may by regulations prescribe, (ii) such
         Spouse has previously provided a consent pursuant to Section 6.2(d),
         (iii) such Spouse has been ordered or required in such judgment, order,
         decree, or settlement to pay an amount to the Plan in connection with
         the ERISA fiduciary responsibility violation, or (iv) such Spouse
         retains the right to receive the survivor annuity in such judgment,
         order, decree, or settlement.

                  For purposes of this Section, the survivor annuity payable
         pursuant to Section 6.1(a) shall be determined as if (i) the
         Participant terminated employment on the date of the offset, (ii) there
         was no offset, (iii) this Plan permitted commencement of benefits only

         survivor annuity described in Section 6.1(a), and the amount of the
         Preretirement Survivor Annuity described in Section 5.5(g) is equal to
         the amount of the survivor annuity payable under Section 6.1(a).
