ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

On March 31, 2000, Phillips Petroleum Company, a Delaware corporation
(Phillips), Duke Energy Corporation, a North Carolina corporation (Duke
Energy) and Duke Energy Field Services, LLC, a Delaware limited liability
company (Field Services), consummated the combination of Duke Energy's gas
gathering and processing business with Phillips' gas gathering, processing and
marketing segment in Field Services. Phillips owns 30.3 percent of Field
Services and Duke Energy owns 69.7 percent.

In connection with the combination, Field Services borrowed approximately
$2.75 billion of short-term debt. The proceeds of the debt were used to make
one-time cash distributions of approximately $1.2 billion to both Phillips and
Duke Energy and to pay $325 million and $20 million to Duke Energy and to
Phillips, respectively, as reimbursement for the acquisition of additional
assets since the Contribution Agreement by and among Phillips, Duke Energy and
Field Services was signed on December 16, 1999.

The Amended and Restated Limited Liability Company Agreement of Field Services,
dated as of March 31, 2000, by and between Phillips Gas Company and Duke Energy
Field Services Corporation, is attached hereto as Exhibit 99.1 and is
incorporated herein by reference.

Concurrently with the consummation of the combination transaction, Phillips,
Duke Energy, Field Services and Duke Energy Field Services Corporation entered
into a Parent Company Agreement, dated as of March 31, 2000, which is attached
hereto as Exhibit 99.2 and is incorporated herein by reference.

The press release issued by Phillips in connection with the consummation of the
combination is attached hereto as Exhibit 99.3 and is incorporated herein by
reference.


ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS.

(b) Pro Forma Financial Information.

      Basis of Presentation

      The following unaudited pro forma financial statements have been prepared
      from the historical financial statements of Phillips, adjusted to reflect
      the contribution to, and participation in, Field Services.  For
      presentation purposes, the transaction has been reflected in two
      parts--Phillips' disposition of its gas gathering, processing and




                                       1


<PAGE>


      marketing segment and simultaneous acquisition of a 30.3 percent equity
      interest in the new company.

      The unaudited pro forma income statement was prepared assuming the
      combination occurred January 1, 1999, while the unaudited pro forma
      balance sheet was prepared as if the combination occurred December 31,
      1999.

      This pro forma financial information is not intended to reflect results
      from operations or the financial position which would have actually
      resulted had the acquisition been effected on the dates indicated.
      Moreover, this pro forma information is not intended to be indicative of
      results of operations or financial position which may be obtained in the
      future.

      This pro forma financial information should be read in conjunction with
      the historical financial statements included in Phillips' Annual Report on
      Form 10-K for the year ended December 31, 1999. The pro forma adjustments
      use estimates and assumptions based on currently available information.
      Management believes that the estimates and assumptions are reasonable, and
      that the significant effects of the transactions are properly reflected.
      However, actual results may differ from the estimates and assumptions
      used.

      This pro forma financial information does not include anticipated
      synergies from operating efficiencies which should result from the
      formation of the new company, nor does it include any anticipated benefit
      from Phillips' receipt of $1.22 billion in cash upon the closing of the
      transaction.  Management estimates that if debt bearing an estimated
      interest rate of 7 percent had been paid off on January 1, 1999,
      using the $1.22 billion cash receipt, it would have increased 1999 pro
      forma net income by approximately $64 million.

NOTES TO UNAUDITED PRO FORMA                       PHILLIPS PETROLEUM COMPANY
FINANCIAL STATEMENTS


(a)   Adjustment to remove Phillips' Gas Gathering, Processing and Marketing
      (GPM) segment from consolidation.

(b)   Adjustment to include $19 million in earnings from Phillips'
      30.3 percent equity interest in Field Services.  The estimate of
      1999 earnings for Field Services is based upon pro forma financial
      results of Field Services as if Phillips' GPM segment and Duke Energy's
      gas gathering and processing business had been contributed to it on
      January 1, 1999. Earnings also include a $48 million adjustment for
      the amortization of the basis difference between the book value of
      Phillips' contribution to Field Services and its 30.3 percent interest
      in the equity of Field Services. This difference is expected to be
      amortized over 15 years.  The tax on these adjustments to earnings
      was calculated at an estimated rate of 38 percent.

(c)   The company estimates that if debt bearing an estimated interest rate
      of 7 percent had been paid off on January 1, 1999, using the
      $1.22 billion cash receipt, it would have increased 1999 pro forma
      net income by approximately $64 million.  However, that benefit is
      not reflected as a pro forma adjustment since it is not directly
      attributable to the transaction presented.

(d)   Adjustment to reflect Phillips' receipt of $1.22 billion in cash upon
      the closing of the transaction.

(e)   Adjustment to reclassify loans and advances to GPM to investment in
      Field Services.

(f)   Adjustment to taxes payable and deferred taxes as a result of the
      receipt of $1.22 billion from Field Services.

(g)   Adjustment to reclassify the credit balance in the investment in
      Field Services from an asset to a liability.  The credit balance is
      due to the $1.22 billion receipt of cash upon closing exceeding the
      net book value of the contributed GPM assets and liabilities.

      than by breach of this Agreement;

                  (ii) information already in the possession of a Member or any
      of its Affiliates before disclosure to it under this Agreement and which
      was not acquired directly or indirectly from the other Member or any of
      its Affiliates and which is not the subject of a confidentiality agreement
      in favor of the provider of such information;

                  (iii) information lawfully obtained from a third party that
      is free to disclose such information;

                  (iv) information developed or created by a Member or any of
      its Affiliates (other than the Company or its Subsidiaries) independent
      of this Agreement;

                  (v) information required to be disclosed at any time after the
      date one year after the date hereof by a Member or any of its Affiliates
      to a third party contemplating purchasing shares in that Member in order
      to permit such third party to decide whether or not to proceed and what
      price to offer; PROVIDED that such third party shall prior to any such
      disclosure have entered into a confidentiality agreement with such Member
      and its Affiliates on terms no less strict than the terms of this Section
      4.3;

                  (vi) information requested by any Governmental Entity entitled
      by Law to require the same; PROVIDED that prior to such disclosure if
      practicable, the disclosing Member shall notify in writing the owner of
      such information (where the identity of such owner can be reasonably
      determined) that such request has been made; PROVIDED FURTHER that the
      Member seeking to rely on an exemption contained in this Section 4.3(b)
      shall



                                      -17-

      provide such evidence as the other Member may reasonably require to
      prove that the information sought to be exempted falls within the relevant
      category; and

                  (vii) information that a Member or its Affiliates must
      disclose under applicable securities Laws or stock exchange regulations.

            (c) The restrictions contained in Section 4.3(a) shall last until
the earlier of the IPO and the date two years from the relevant disclosure.

                                    ARTICLE V
                       LIQUIDITY AND TRANSFER RESTRICTIONS

      Section 5.1 Transfers of the Company Interests. For the period from the
date hereof until the consummation of the IPO, (a) DEFS Holding shall directly
own and hold all of Duke's Company Interests and shall have no other assets or
liabilities and (b) PGC shall directly own and hold all of Phillips' Company
Interests and shall have no other assets or liabilities.

      Section 5.2 Change of Control. (a) If prior to the IPO, (i) a Change of
Control occurs with respect to DEFS Holding, PGC shall have the option to
purchase DEFS Holding's Company Interest for Fair Market Value pursuant to the
provisions of Section 5.2(b), (c) and (d), or (ii) a Change of Control occurs
with respect to PGC, DEFS Holding shall have the option to purchase PGC's
Company Interest for Fair Market Value pursuant to the provisions of Section
5.2(b), (c) and (d).

            (b) In the event of a transaction giving rise to a Change of Control
of either DEFS Holding or PGC, the Member who has suffered such a Change of
Control (the "Changing Member") shall promptly (and in any event within three
days of the consummation of such transaction) deliver notice (the "Control
Notice") to the other Member (the "Non-Changing Member") of such Change of
Control transaction. The Non-Changing Member shall have the right, to be
exercised by notice (the "Control Acceptance") on or before the 60th day
following receipt of the Control Notice (the "Control Offer Period"), to elect
to purchase the Company Interest of the Changing Member for Fair Market Value as
of the date of the Change of Control. The Control Acceptance shall set forth the
name of a nationally recognized appraisal firm (which may be an investment
banking, accounting or other firm that performs appraisal and valuation
services) designated by the Non-Changing Member as its appraisal firm (the
"Non-Changing Member Appraiser").

            (c) If the Non-Changing Member timely delivers the Control
Acceptance during the Control Offer Period, within 15 days from the date of
receipt of the Control Acceptance, the Changing Member shall notify the
Non-Changing Member in writing of the name of an appraisal firm (which may be an
investment banking, accounting or other firm that performs appraisal and
valuation services) designated as the Changing Member's appraisal firm (the
"Changing Member Appraiser"); provided, however, that if the Changing Member
fails to select an appraisal firm, and the Changing Member is DEFS Holding, the
Changing Member Appraiser shall be Deloitte & Touche L.L.P., or, if the Changing
Member is PGC, the Changing Member Appraiser shall be Ernst & Young L.L.P.;
provided, further, that if Deloitte & Touche L.L.P. or Ernst & Young L.L.P., as
the case may be, fails to accept the appointment within 30 days from the date of
receipt by the Changing Member of the Control Acceptance, the



                                      -18-
<PAGE>


Control Appraiser Committee shall consist solely of the Non-Changing Member
Appraiser. Except as provided in the second proviso of the immediately preceding
sentence, the Non-Changing Member Appraiser and the Changing Member Appraiser
shall jointly choose a third appraisal firm (which may be an investment banking,
accounting or other firm that performs appraisal and valuation services) within
15 days after the appointment of the Non-Changing Member Appraiser (PROVIDED,
HOWEVER, that if they fail to select a third appraisal firm within 15 days after
the appointment of the Non-Changing Member Appraiser, such third firm (which
shall be an investment banking, accounting or other firm that performs appraisal
and valuation services) will be selected by the American Arbitration Association
at the request of either party within 10 days after such request) (the "Neutral
Control Appraiser", and together with the Changing Member Appraiser and the
Non-Changing Member Appraiser, the "Control Appraiser Committee"). Once the
Control Appraiser Committee has been chosen, each of the Changing Member and
Non-Changing Member shall submit proposed Fair Market Values of the Changing
Member's Company Interest to the Control Appraiser Committee, together with any
supporting documentation such Member deems appropriate, as soon as practicable,
but in no event earlier than 30 days after the date of receipt of the Control
Acceptance nor later than (i) 30 days after the date of selection of the Neutral
Control Appraiser or (ii) in the event of the failure of Deloitte & Touche
L.L.P. or Ernst & Young L.L.P., as the case may be, to accept the appointment
within the required time period, 60 days from the date of receipt by the
Non-Changing Member of the Control Notice. If either Member fails to submit its
proposed Fair Market Value within the required time period, the Fair Market
Value proposed by the other Member (assuming such other Member has submitted its
proposed value within the required time period) shall be deemed to be the Fair
Market Value of the Changing Member's Company Interest for purposes of this
Section 5.2. If both Members submit their respective proposed values on a timely
basis, the Control Appraiser Committee shall determine, by majority vote, the
Fair Market Value as of the date of the Change of Control of the Changing
Member's Company Interest as promptly as possible (and in any event on or before
the 30th day after submittal of the competing proposals), which determination
shall be final and binding on the Members. The cost of such appraisal shall be
paid in equal portions by DEFS Holding and PGC. Each of the Changing Member and
the Non-Changing Member shall provide to the other and, if applicable, the
Control Appraisal Committee, all information reasonably requested by them.

            (d) The closing of the Non-Changing Member's acquisition of the
Changing Member's Company Interest shall be consummated on or before the 60th
day after the determination of the Fair Market Value in accordance with Section
5.2(c). The acquisition shall be consummated at a closing held at the principal
offices of the Company (unless otherwise mutually agreed by the Changing Member
and the Non-Changing Member) at which time the purchase price, payable in the
form of immediately available funds, shall be delivered to the Changing Member,
and the Changing Member shall deliver or cause to be delivered to the
Non-Changing Member (or at the election of the Non-Changing Member, its
designee) such transfer documentation reasonably acceptable to the Non-Changing
Member as shall be required to evidence the transfer of the Changing Member's
Company Interest free and clear of all liens and encumbrances, except those
created under this Agreement.

                                     ARTICLE VI
                  CAPITAL CONTRIBUTIONS AND CAPITAL ACCOUNTS

      Section 6.1 Capital Contributions. The initial Capital Contributions made
to the Company by the Members shall be the property contributed by the Members
pursuant to Article II of the Contribution Agreement.

      Section 6.2 Additional Capital Contributions. The Members may make
additional Capital Contributions or loans to the Company as requested by the
Company Board. Except for the Capital Contributions required of the Members
pursuant to Section 6.1, no Member shall be required to make any Capital
Contributions to the Company.

      Section 6.3 Capital Accounts. A "Capital Account" shall be maintained for
each Member on the books of the Company in compliance with the requirements of
Code Section 704(b) and the Regulations thereunder. The initial Capital Accounts
of the Members shall be (prior to reduction for the amount of any cash
distributed to DEFS Holding and PGC on the Closing Date), in the case of DEFS
Holding, $3,585,500,000 and, in the case of PGC, $2,139,500,000. Each Member's
Capital Account shall be increased by (i) the Capital Contributions of such
Member, (ii) Profits and items of income or gain allocated to such Member as set
forth in Article VII hereof, (iii) any positive adjustment to such Capital
Account by reason of an adjustment to the Book Value of Company assets, and (iv)
the amount of Company liabilities assumed by such Member or which are secured by
any property distributed to such Member. Each Member's Capital Account shall be
decreased by (i) the amount of any cash and the Book Value of any property
distributed to such Member, (ii) Losses, Nonrecourse Deductions, Partner
Nonrecourse Deductions, and items of loss or deduction allocated to such Member
as set forth in Article VII hereof, (iii) any negative adjustment to such
Capital Account by reason of an adjustment to the Book Value of Company assets,
and (iv) the amount of any liabilities of such Member assumed by the Company or
which are secured by property contributed by such Member to the Company. In
determining the amount of any liability for purposes of the preceding two
sentences, there shall be taken into account Code Section 752(c) and any other
applicable provisions of the Code and Regulations.

      Section 6.4 Return of Contributions. Although a Member has the right to
receive Distributions in accordance with the terms of this Agreement, a Member
is not entitled to the return of any part of its Capital Contributions or to be
paid interest in respect of either its Capital Account or its Capital
Contributions. An unrepaid Capital Contribution is not a liability of the
Company or of any Member. No Member will be required to contribute or to lend
any cash or property to the Company to enable the Company to return any Member's
Capital Contributions.

                                   ARTICLE VII
                        PROFITS AND LOSSES; DISTRIBUTIONS

      Section 7.1 Allocation of Profit and Losses. (a) In General. This Section
7.1 sets forth the general rules for book allocations to the Members and shall
apply to allocations with respect to the operations and liquidation of the
Company, maintaining the books and records of the Company and computing the
Members' Capital Accounts or share of Profit, Losses, other items or
distributions pursuant to this Agreement, in each case as required for U.S.
Federal income tax purposes under Code Section 704(b) and the Regulations
thereunder. These provisions do not apply to the requirement that the Company
maintain books and records for financial reporting purposes in accordance with
Section 4.1.

            (b) Profits and Losses. Commencing on the Closing Date, Profits and
Losses shall be allocated among the Members in accordance with their respective
Percentage Interests in the Company; PROVIDED, HOWEVER, that the Company shall
make special allocations to the extent required pursuant to Article V of Annex A
to the Contribution Agreement.

      Section 7.2 Limitations on Allocations. Notwithstanding the general
allocation rules set forth in Section 7.1 hereof, the following special
allocation rules and limitations shall apply with respect to maintaining the
Company's books and records and computing the Members' Capital Accounts or share
of Profits, Losses, other items or distributions pursuant to this Agreement, in
each case as required for U.S. Federal income tax purposes under Code Section
704(b) and the Regulations thereunder.

            (a) Limitations on Loss Allocations. The losses allocated to any
Member pursuant to Section 7.1(b) hereof with respect to any Fiscal Year shall
not exceed the maximum amount of losses that can be so allocated without causing
such Member to have an Adjusted Capital Account Deficit at the end of such
Fiscal Year. In the event some but not all of the Members would have Adjusted
Capital Account Deficits as a consequence of an allocation of losses pursuant to
Section 7.1(b) hereof, the limitation set forth in this Section 7.2(a) shall be
applied on a Member-by-Member basis and any such losses not allocable to a
Member as a result of such limitation shall be allocated to the other Members in
accordance with their positive Capital Account balances so as to allocate the
maximum possible losses to each Member under Regulation Section
1.704-1(b)(2)(ii)(d).

            (b) Qualified Income Offset. If in any Fiscal Year a Member
unexpectedly receives an adjustment, allocation or distribution described in
Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6), and such adjustment,
allocation, or distribution causes or increases an Adjusted Capital Account
Deficit for such Member, then, before any other allocations are made under this
Article VII or otherwise, such Member shall be allocated items of income and
gain (consisting of a PRO RATA portion of each item of Company income, including
gross income and gain) in an amount and manner sufficient to eliminate such
Adjusted Capital Account Deficit as quickly as possible; PROVIDED that an
allocation pursuant to this Section 7.2(b) shall be made only if and to the
extent that the Member would have an Adjusted Capital Account Deficit after all
other allocations provided for in this Article VII have been made as if this
Section 7.2(b) were not in this Agreement. This Section 7.2(b) is intended to
constitute a "qualified income offset" as provided in Regulation Section
1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

            (c) Partnership Minimum Gain Chargeback. If there is a net decrease
in Partnership Minimum Gain during any Fiscal Year, then, except as provided in
Regulation Section 1.704-2(f)(2), (3), or (5), each Member shall be allocated
items of income and gain for such Fiscal Year (and, if necessary, for subsequent
Fiscal Years) in proportion to, and to the extent of, such Member's share of the
net decrease in Partnership Minimum Gain during such Fiscal Year. Allocations
pursuant to the previous sentence shall be made in proportion to the respective
amounts required to be allocated to each Member pursuant thereto and the items
to be so allocated shall be determined in accordance with Regulation Sections
1.704-2(f)(6) and 1.704-2(j)(2). To the extent that this Section 7.2(c) is
inconsistent with Regulation Section 1.704-2(f) or incomplete with respect to
such Regulations, the Partnership Minimum Gain chargeback provided for herein
shall be applied and interpreted in accordance with such Regulation.

            (d) Partner Nonrecourse Debt Minimum Gain Chargeback. If there is a
net decrease in Partner Nonrecourse Debt Minimum Gain during any Fiscal Year,
then, except as provided in Regulation Section 1.704-2(i)(4), each Member with a
share of Partner Nonrecourse Debt Minimum Gain shall be allocated items of
income and gain for such Fiscal Year (and, if necessary, for subsequent Fiscal
Years) in proportion to, and to the extent of, such Member's share of the net
decrease in Partner Nonrecourse Debt Minimum Gain during such Fiscal Year.
Allocations pursuant to the previous sentence shall be made in proportion to the
respective amounts required to be allocated to each Member pursuant thereto and
the items to be so allocated shall be determined in accordance with Regulation
Sections 1.704-2(i)(4) and 1.704-2(j)(2). To the extent that this Section 7.2(d)
is inconsistent with Regulation Section 1.704-2(i) or incomplete with respect to
such Regulation, the Partner Nonrecourse Debt Minimum Gain chargeback provided
for herein shall be applied and interpreted in accordance with such Regulation.

            (e) Nonrecourse Deductions. Nonrecourse Deductions for any Fiscal
Year shall be specially allocated to the Members in proportion to each of their
respective Percentage Interests in the Company. This provision is to be
interpreted in a manner consistent with Regulation Sections 1.704-2(b)(1) and
1.704-2(e).

            (f) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions
shall be allocated among the Members in accordance with the ratios in which the
Members share the economic risk of loss for the Partner Nonrecourse Debt that
gave rise to those deductions. This allocation is intended to comply with the
requirements of Regulation Section 1.704-2(i) and shall be interpreted and
applied consistently therewith.

            (g) Limited Effect and Interpretation. The special rules set forth
in Sections 7.2(a), (b), (c), (d), (e) and (f) (the "Regulatory Allocations")
shall be applied only to the extent required by applicable Regulations for the
resulting allocations provided for in this Section 7.2, taking into account such
Regulatory Allocations, to be respected for U.S. Federal income tax purposes.
The Regulatory Allocations are intended to comply with the requirements of
Regulation Sections 1.704-1(b), 1.704-2 and 1.752-1 through 1.752-5, inclusive
and shall be interpreted and applied consistently therewith.

            (h) Offsetting Allocations. The Regulatory Allocations may not be
consistent with the manner in which the Members intend to divide Company
Profits, Losses, and other similar items. It is the intent of the Members that,
to the extent possible, all Regulatory



                                      -22-
<PAGE>


Allocations shall be offset either with other Regulatory Allocations or with
special allocations of other items of Company income, gain, loss or deduction
pursuant to this Section 7.2(h). Therefore, notwithstanding any other provision
of this Article VII (other than the Regulatory Allocations), the Company shall
make such offsetting special allocations of Company income, gain, loss or
deduction in a manner such that, after the offsetting allocations are made, each
Member's Capital Account Balance is, to the extent possible, equal to the
Capital Account balance such Member would have had if the Regulatory Allocations
were not part of this Agreement and all Company items were allocated pursuant to
Section 7.1 hereof.

      Section 7.3 Restoration of Negative Capital Accounts. At no time shall a
Member with a negative balance in its Capital Account have any obligation to the
Company or to any other Member to restore such negative balance.

      Section 7.4 Interim Allocations Relating to Transferred Company Interests.
Notwithstanding any other provision of this Agreement or the Contribution
Agreement, in the event of a change in a Member's Percentage Interest in the
Company as a result of a Transfer or deemed Transfer of a Member's Company
Interest during a Fiscal Year, the allocations required under this Article VII
shall be made with respect to the Members for the portion of the Fiscal Year
through the date of the Transfer and after the date of the Transfer based on an
interim closing of the Company's books. The effective date of any such Transfer
shall be the actual date of the Transfer as recorded on the books of the
Company. This Section 7.4 shall also apply for purposes of computing a Member's
Capital Account.

      Section 7.5 Code Section 704(c) Allocations. (a) In accordance with Code
Section 704(c) and the Regulations thereunder, income, gain, loss and deduction
with respect to any property contributed to the capital of the Company or any
Subsidiary thereof that is treated as a partnership or disregarded entity for
U.S. Federal income tax purposes shall, solely for U.S. Federal income tax
purposes, be allocated among the Members so as to take account of any variation
between the adjusted tax basis of such property to the Company for U.S. Federal
income tax purposes and its Book Value (computed in accordance with the
definition of Book Value) using the "Traditional Method with Curative
Allocations" as defined in Regulation Section 1.704-3(c).

            (b) In the event the Book Value of any asset of the Company (or any
Subsidiary thereof that is treated as a partnership or disregarded entity for
U.S. Federal income tax purposes) is adjusted pursuant to subparagraph (i) of
the definition of Book Value or otherwise pursuant to Code Section 704(b) and
the Regulations thereunder, subsequent allocations of income, gain, loss and
deduction with respect to any such asset so adjusted shall take account of any
variation between the adjusted tax basis of such asset for U.S. Federal income
tax purposes and the Book Value in the same manner as under Code Section 704(c),
the Regulations thereunder and Section 7.5(a).

            (c) Allocations pursuant to this Section 7.5 are solely for purposes
of U.S. Federal income taxes and shall not affect, or in any way be taken into
account in computing, any Member's Capital Account or share of Profits, Losses
or other items allocated under Section 7.1 or 7.2.

      Section 7.6 Distributions. (a) Distributions Other Than in Liquidation of
the Company. Except as provided in Section 7.6(b) below (and taking into account
deemed distributions, if any, under Section 8.1 which are not re-contributed
pursuant to Section 8.1), Distributions of cash of the Company shall be made at
the end of each quarterly accounting period of the Company, and one Business Day
prior to the date of the IPO, to each Member of the Company in the following
amounts:

                  (i) the greater of (A) the excess of (x) the product of (I)
      the sum of the maximum United States regular Federal income tax rate
      applicable to C corporations under Section 11 of the Code and 4.5 percent
      and (II) the excess, if any, of taxable income and gain over taxable loss
      or deduction of the Company allocated to such Member with respect to such
      period over (y) the amount of any credits allocated to such Member with
      respect to such period for United States regular Federal income tax
      purposes and State income tax purposes and (B) (x) such Member's
      Percentage Interest in the Company multiplied by the quotient of (y) the
      amount calculated under clause (A) with respect to such period for the
      other Member (or Members) (the "Other Member") divided by (z) the Other
      Member's Percentage Interest in the Company; and

                  (ii) such Distributions as the Company Board may determine in
      its discretion pursuant to Section 3.7.

Such Distributions pursuant to clause (i) shall be made in a manner consistent
with the estimated annual tax items of the Company, and Distributions pursuant
to clause (i) for each quarterly accounting period (or portion thereof) shall be
adjusted to the extent Distributions for prior quarterly accounting periods did
not correctly estimate such items.

            (b) Distributions in Liquidation of the Company. Upon the
dissolution or liquidation of the Company, the proceeds of sale of the
properties and assets of the Company that have been sold in liquidation, and all
other properties and assets of the Company not otherwise sold (and valued at
their fair market value), shall be applied and distributed as follows, and in
the following order of priority: (i) first, to the payment of all debts and
liabilities of the Company and the expenses of liquidation not otherwise
adequately provided for; (ii) second, to the setting up of any reserves that are
reasonably necessary for any contingent unforeseen liabilities or obligations of
the Company or of the Members arising out of or in connection with the Company;
(iii) third, to the Members in proportion to the positive balances of each of
their respective Capital Accounts after all allocations have been made to such
Capital Accounts pursuant to this Agreement, until the remaining balances of
such Capital Accounts are zero; and (iv) fourth, the remaining proceeds to the
Members in proportion to each of their Percentage Interests in the Company.

                                 ARTICLE VIII
              WITHHOLDING TAX MATTERS; TAX STATUS AND TREATMENT

      Section 8.1 Withholding. The Company shall comply with all withholding
requirements under U.S. Federal, state, local and foreign tax Laws and shall
remit amounts withheld to, and file required forms with, such applicable Taxing
Authorities. To the extent that the Company withholds and pays over any amounts
to any Taxing Authority with respect to the distributions or allocations to any
Member, the amount withheld (or credited against withholding



                                      -24-
<PAGE>


tax otherwise due) shall be treated as a distribution to such Member in the
amount of the withholding (or credit). In the event of any claimed
overwithholding by the Company, if the Company is required to take any action in
order to secure a refund or credit for the benefit of a Member in respect of any
amount withheld by it, it will take any such action including applying for such
refund on behalf of the Member and paying it over to such Member. If any amount
required to be withheld was not withheld from actual distributions made to a
Member, the Member to which the distribution was made shall reimburse the
Company for such withholding. In the event of any underwithholding by the
Company to a Member, each Member agrees to indemnify and hold harmless the
Company and its subsidiaries from and against any liability, including interest
and penalties, with respect to such underwithholding to such Member. Each Member
agrees to furnish the Company with any representations and forms as shall
reasonably be requested by the Company to assist the Company in determining the
extent of, and in fulfilling, the Company's withholding obligations, if any. The
provisions of this Section 8.1 shall be applied in a manner, taking into
consideration any tiered partnership structure that the Company may be part of,
that reflects the relative economic interests of each Member in the Company.

      Section 8.2 Tax Status. (a) The Company is intended to be treated as a
partnership for U.S. Federal income tax purposes, and each of the Subsidiaries
of the Company organized under the laws of the United States, a State of the
United States or any political subdivision thereof (other than Duke Energy Field
Services Canada Holdings, Inc.) (the "Flow Through Subsidiaries") is intended to
be treated as a partnership or disregarded entity for U.S. Federal income tax
purposes.

      (b) Each of the Members and the Company shall take no action or position
inconsistent with (or that could reasonably be expected to be viewed by the
Internal Revenue Service as inconsistent with), and shall make or cause to be
made all applicable elections with respect to: (i) the treatment of the Company
(or any successor thereto), with respect to all times during the Two Year
Period, as a partnership for U.S. Federal income tax purposes and the treatment
of each of the Flow Through Subsidiaries (or any successor thereto), with
respect to all times during the Two Year Period, as a partnership or disregarded
entity for U.S. Federal income tax purposes; (ii) the treatment of the Company,
with respect to all times during the Two Year Period, as not being a publicly
traded partnership for United States Federal income tax purposes; (iii) the
allocation of the Financing under Regulation Section 1.752-3(a)(3) among the
Members in proportion to their Percentage Interests as of the Closing Date; (iv)
the treatment of the contribution to the Company by DEFS Holding pursuant to
Section 2.2 of the Contribution Agreement as a contribution pursuant to Code
Section 721, the treatment of the distribution to DEFS Holding pursuant to
Section 3.2(c)(2) of the Contribution Agreement (as adjusted pursuant to Section
3.3 thereof) as a distribution pursuant to Code Section 731 and the treatment
that, for purposes of the Code, neither such contribution nor such distribution
is a transfer that constitutes a sale or exchange (or portion thereof) of
property in whole or in part to the Company by a Member in the Company acting in
a capacity other than as a Member of the Company; (v) the treatment of the
contribution to the Company by PGC pursuant to Section 2.3 of the Contribution
Agreement (the "PGC Contribution") as a contribution pursuant to Code Section
721, the treatment of the distribution to PGC pursuant to Section 3.2(c)(1) of

that, for purposes of the Code, neither the PGC

<PAGE>


Contribution nor the PGC Distribution is a transfer that constitutes a sale or
exchange (or portion thereof) of property in whole or in part to the Company by
a Member in the Company acting in a capacity other than as a Member of the
Company (except in the case of this clause (v) that the Members and the Company
shall treat (except to the extent Duke, Phillips, the Members and the Company
agree in writing or are required by the Neutral Firm to treat otherwise) an
amount of the PGC Distribution equal to the Disguised Sale Amount as proceeds of
a sale by PGC to the Company under Code Section 707(a) and an amount of the PGC
Contribution equal in fair market value to the Disguised Sale Amount as property
that is sold by PGC to the Company under Code Section 707(a) (such property
treated as having been sold having regular federal income tax basis equal to the
aggregate regular Federal income tax basis of the property contributed in the
PGC Contribution multiplied by a fraction the numerator of which is the
Disguised Sale Amount and the denominator of which is the value of the property
contributed in the PGC Contribution, such value being for this purpose
$2,139,500,000)); and (vi) the treatment of the merger of PGCSI into DEFS
Holding pursuant to Section 2.2(a) of the Parent Company Agreement as a
"reorganization" within the meaning of Code Section 368(a) in which no gain or
loss is recognized to PGC, DEFS Holding, the Company, Duke, Phillips or any
other Person.

      Section 8.3 Tax Matters Partner; Tax Elections. (a) The Company hereby
elects to have a "tax matters partner" as provided under Code Section
6231(a)(7)(B) (the "Tax Matters Partner"). DEFS Holding is hereby designated as
such Tax Matters Partner.

            (b) The Company shall make all elections required under United
States Income Tax Laws and regulations and any similar state statutes and shall
make the following elections:

                  (1)   Adopt the calendar year as the annual accounting
                        period;

                  (2)   Adopt the accrual method of accounting; and

                  (3)   Adopt the maximum allowable accelerated method and
                        shortest permissible life for determining depreciation
                        deductions.

            (c) At the request of any Member, the Company shall make the
election provided for in Section 754 of the Code.

                                   ARTICLE IX
                   DISSOLUTION, WINDING-UP AND TERMINATION

      Section 9.1 Dissolution. The Company shall dissolve and its affairs shall
be wound up on the first to occur of the following events (each a "Dissolution
Event"):

            (a) the consent of the Company Board pursuant to Section 3.7; or

            (b) entry of a decree of judicial dissolution of the Company
under Section 18-802 of the Act.



                                      -26-
<PAGE>


      Section 9.2 Winding-Up and Termination. (a) On the occurrence of a
Dissolution Event, the Company Board shall select one or more Persons to act as
liquidator. The liquidator shall proceed diligently to wind up the affairs of
the Company and make final distributions as provided in Section 7.6(b) and in
the Act. The costs of winding up shall be borne as a Company expense. Until
final distribution, the liquidator shall continue to operate the Company
properties with all of the power and authority of the Company Board.

            (b) All distributions in kind to the Members shall be made subject
to the liability of each distributee for costs, expenses and liabilities
theretofore incurred or for the payment of which the Company has committed prior
to the date of termination. The distribution of cash or property to a Member in
accordance with the provisions of Section 7.6(b) and this Section 9.2
constitutes a complete return to the Member of its Capital Contributions and a
complete distribution to the Member of its share of all the Company's property
and constitutes a compromise to which all Members have consented within the
meaning of Section 18-502(b) of the Act.

            (c) On completion of such final distribution, the liquidator shall
file a Certificate of Cancellation with the Secretary of State of the State of
Delaware and take such other actions as may be necessary to terminate the
existence of the Company.

                                    ARTICLE X
                                  MISCELLANEOUS

      Section 10.1 Counterparts. This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement, and
shall become effective when one or more counterparts have been signed by each of
the parties hereto and delivered (including by facsimile) to the other party.

      Section 10.2 Governing Law; Jurisdiction and Forum; Waiver of Jury
Trial. (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware without reference to the choice of law
principles thereof.

            (b) Each Member hereto irrevocably submits to the jurisdiction of
any Delaware state court or any federal court sitting in the State of Delaware
in any action arising out of or relating to this Agreement, and hereby
irrevocably agrees that all claims in respect of such action may be heard and
determined in such Delaware state or federal court. Each Member hereby
irrevocably waives, to the fullest extent it may effectively do so, the defense
of an inconvenient forum to the maintenance of such action or proceeding. The
Members further agree, to the extent permitted by Law, that final and
unappealable judgment against any of them in any action or proceeding
contemplated above shall be conclusive and may be enforced in any other
jurisdiction within or outside the United States by suit on the judgment, a
certified copy of which shall be conclusive evidence of the fact and amount of
such judgment.

            (c) To the extent that any Member has or hereafter may acquire any
immunity from jurisdiction of any court or from any legal process (whether
through service or notice, attachment prior to judgment, attachment in aid of
execution, execution or otherwise) with respect to itself or its property, each
Member hereby irrevocably waives such immunity in respect of its obligations
with respect to this Agreement.

other things, the mutual waivers and certifications set forth above in this
Section 10.2.

      Section 10.3 Entire Agreement. This Agreement constitutes the entire
agreement of the Members between the Members with respect to the subject matter
hereof and there are no agreements, understandings, representations or
warranties between the Members other than those set forth or referred to herein.
This Agreement is not intended to confer upon any person not a party hereto any

not be amended without the consent of Duke and Phillips as provided in Section
10.7 of this Agreement and Section 4.1 of the Parent Company Agreement.

      Section 10.4 Notices. All notices and other communications to be given to
any party hereunder (including notices to Directors under Section 3.6) shall be

      Section 10.5 Successors and Assigns. This Agreement shall be binding upon
and inure to the benefit of the Members (and Duke and Phillips to the extent
provided in Section 10.3) and their respective successors and permitted assigns;

of its obligations under this Agreement without the express prior written

beginning on the first day of the taxable period to which the Tax Proceeding
relates) of greater than $7,575,000, the Company shall not settle, compromise or
abandon any such Tax Proceeding without obtaining the prior written consent,
which consent shall not be unreasonably withheld, of Phillips and (B) in the
case of any proposed settlement of any such Tax Proceeding, which settlement
will result in aggregate Tax payments by Duke with respect to the period
beginning on the Closing Date and ending on the second anniversary of the
Closing Date (or, if the Tax Proceeding relates to a taxable period (or portion
thereof) after such second anniversary, then with respect to the two year period
beginning on the first day of the taxable period to which the Tax Proceeding
relates) of greater than $17,425,000, the Company shall not settle, compromise
or abandon any such Tax Proceeding without obtaining the prior written consent,
which consent shall not be unreasonably withheld, of Duke. In the event that
Duke or Phillips reasonably withholds such consent pursuant to the preceding
clause (vi)(A) or (B), the parties shall negotiate in good faith to resolve
their differences and, failing that, the Neutral Firm shall resolve such
disagreement. The above provisions of this Section 4.3(a) shall cease to apply
with respect to taxable periods beginning after the consummation of the IPO,
except to the extent that failure of such provisions to apply could reasonably
be expected to affect any member of the Phillips Group or the Duke Group (other
than in its capacity as a direct or indirect shareholder, or affiliate of such a
shareholder, of the Corporation).

          (b) The Company shall present (such presentation to be made (i) in
the case of a Tax Return for a Company taxable year ending on December 31st, no
later than July 1st in the year following the end of such Company taxable year
and (ii) in the case of a Tax Return for a Company taxable year ending on a date
other than December 31st, no later than the date that is six months following
the end of such Company taxable year) any Federal Income Tax Returns of the
Company to Phillips for Phillips' review and shall revise such Tax Returns prior
to filing to reflect any reasonable comments requested in good faith by Phillips
in writing within 15 Business Days after such presentation of such Tax Returns
to Phillips; PROVIDED, HOWEVER, that in the event that the Company or Duke
disagrees with any such comments of Phillips, then the Company, Duke and
Phillips shall endeavor to resolve their disagreement over such comments and,
failing that, the Neutral Firm shall resolve such disagreement prior to the date
such Tax Returns are due (including extensions) and such Tax Returns shall be
filed in such manner as the Neutral Firm determines. The fees and expenses of
the Neutral Firm in connection with this Section 4.3(b) shall be allocated
between Phillips and Duke by the Neutral Firm. At Duke's or Phillips' request,
the Company shall make available to Duke and Phillips, respectively, for their
review at least 15 Business Days prior



                                      -11-

to the due date (including extensions) any state, local or foreign Income Tax
Returns of the Company or its Subsidiaries. The above provisions of this Section
4.3(b) shall cease to apply with respect to taxable periods beginning after the
consummation of the IPO, except to the extent that failure of such provisions to
apply could reasonably be expected to affect any member of the Phillips Group
(other than in its capacity as a direct or indirect shareholder, or affiliate of
such a shareholder, of the Corporation).

          (c) Cooperation and Exchange of Information. Duke, Phillips, the
Company and DEFS Holding (and the Corporation, from and after the Merger) shall
(and shall cause their respective Subsidiaries to) cooperate with one another
with respect to Tax matters. As soon as practicable, but in any event within 30
days after the request of Duke or Phillips, from and after the Closing Date, the
Company shall deliver to Duke or Phillips, respectively, such information and
data concerning the Company and its Subsidiaries and make available such
employees of the Company and its Subsidiaries as Duke or Phillips may reasonably
request (including providing the information and data reasonably required by
Duke's and Phillips' customary Tax and accounting questionnaires) in order to
enable Duke and Phillips to complete and file all Tax Returns which they each
may be required to file with respect to the Company and its Subsidiaries or to
respond to Tax audits or other inquiries relating to Taxes by any Governmental
Entities with respect to such operations and to otherwise enable Duke and
Phillips each to satisfy their respective accounting, Tax and other legitimate
business requirements. Such cooperation and information shall include provision
of powers of attorney to Duke or Phillips relating to Tax matters (e.g., for the
purpose of signing Returns and defending audits) and promptly forwarding copies
of appropriate notices and forms or other communications received from or sent
to any Governmental Entity that relate to the Company and its Subsidiaries, and
providing copies of all relevant Tax Returns, together with accompanying
schedules and related workpapers, documents relating to rulings or other
determinations by any Governmental Entities and records concerning the ownership
and tax basis of property, which the Company, the Corporation and their
Subsidiaries may possess. The Company and DEFS Holding (and the Corporation,
from and after the time of the Merger) shall (and shall cause their respective
Subsidiaries to) make their respective employees and facilities available on a
mutually convenient basis to provide explanation of any documents or information
provided hereunder. The above provisions of this Section 4.3(c) shall cease to
apply with respect to taxable periods beginning after the consummation of the
IPO, except to the extent that failure of such provisions to apply could
reasonably be expected to affect any member of the Phillips Group or the Duke
Group (other than in its capacity as a direct or indirect shareholder or
affiliate of such a shareholder, of the Corporation). Notwithstanding any other
provision, (i) Duke shall not be required to provide any Person with any
consolidated, combined, affiliated or unitary Income Tax Return or copy thereof
that includes Duke or any other member of the Duke Group and (ii) Phillips shall
not be required to provide any Person with any consolidated, combined,
affiliated or unitary Income Tax Return or copy thereof that includes Phillips
or any other member of the Phillips Group.

          Section 4.4 Debt Repayment. From and after consummation of the IPO,
to the extent that proceeds from the IPO (or any other funds contributed to the
Company or any of its Subsidiaries) are used to repay debt owed by the Company
or any of its Subsidiaries (for so long as the Company or such Subsidiary is
treated as a partnership for federal income tax purposes), such funds shall be
contributed to the Company and its Subsidiaries by the limited liability company
interest holders or other equity interest holders in the Company or such
Subsidiaries in proportion to the allocation of debt to such holders provided in
Section 8.2(b)(iii) of the LLC Agreement.

to assume the obligations of Duke or Phillips, as applicable, under this

                                   ARTICLE VI

                            TERMINATION OF AGREEMENTS

          Section 6.1 Termination of Agreements. The Governance Agreement is
hereby terminated in its entirety and shall be void and have no further force
and effect; PROVIDED, HOWEVER, that such termination shall not relieve any party
thereto of any liability for any breach of the Governance Agreement that
occurred prior to the termination thereof. From and after the termination of the
Governance Agreement, any reference to the Governance Agreement in Annex B of
the Contribution Agreement (or in any definition of a defined term used in Annex
B) shall be deemed to be a reference to the corresponding provision or
provisions of this Agreement or the LLC Agreement.

                                  ARTICLE VII

                                EMPLOYEE MATTERS


          Section 7.1 Definitions; Controlling Provisions. As used in this
Article VII, (i) the terms "DEFS" and "TEPPCO" shall have the meanings assigned
to such terms in the Contribution Agreement, (ii) the terms "Bonuses," "Change
in Control Severance Plan," "Continued Employees," "DEFS Employee," "Duke FSP,"
"Eligible Expenses," "Employee," "New Welfare Plans," "Old Welfare Plans," "PGC

mean any individual who is, immediately prior to the date hereof, an Employee of
TEPPCO, and (v) the term "DEFS Severance Plan" shall mean that certain 2000 Duke
Energy Field Services Severance Benefits Plan as in effect on April 1, 2000. The
terms of this Article VII shall govern and control to the extent they are
inconsistent or conflict with the terms of Annex A to the Contribution
Agreement, and the provisions of Sections 7.3, 7.4 and 7.5 shall be deemed to be
a part of Annex A to the Contribution Agreement



                                      -13-
<PAGE>


for purposes of the indemnification provisions of Sections 9.1(iii), 9.2(a)(iv)
and 9.2(b)(iv) of the Contribution Agreement. The provisions of Section 5.1 of
Annex A to the Contribution Agreement shall apply with respect to the
compensation and benefit matters addressed in this Article VII.

          Section 7.2 Transfer of Employees. If a DEFS Employee or a PGC
Employee is to be transferred to the Company pursuant to the terms of Annex A to
the Contribution Agreement, then the Company may direct Duke and Phillips,
respectively, to cause the transfer of such employee to be made to the Company
or to a Subsidiary of the Company that is designated by the Company. Continued
Employees may be employed by the Company or any Affiliate of the Company as
determined by the Company from time to time in its sole discretion.

          Section 7.3 TEPPCO Employees. For all purposes of Annex A to the
Contribution Agreement and this Article VII (except where specifically provided
otherwise), each TEPPCO Employee shall be considered a Retained DEFS Employee.
Duke shall have no obligation under Section 3.2 of Annex A to the Contribution
Agreement to reimburse the Company for a pro-rata portion of the Bonuses for
calendar year 2000 that are paid to Retained DEFS Employees who are TEPPCO
Employees. Schedule 7.3 to this Agreement sets forth a list of agreements
relating to TEPPCO Employees that shall be considered to be among the agreements
listed in Schedule 2.5(a)(i) or Schedule 2.5(a)(ii) to Annex A to the
Contribution Agreement (as indicated on Schedule 7.3 to this Agreement);
provided, however, that the Company shall have no reimbursement obligation to
Duke with respect to any such agreement that is considered to be among the
agreements listed in Schedule 2.5(a)(i) to Annex A to the Contribution
Agreement.

          Section 7.4 Welfare Benefits. (a) In order to permit benefits
transition with respect to Retained DEFS Employees, for the period beginning on
the date hereof and ending on the earliest of (i) December 31, 2000, (ii) such
date as Duke shall cease to have a greater than 50%, direct or indirect,
ownership interest in the Company, or (iii) such date as the Company or Duke
shall designate with respect to any particular Old Welfare Plan (provided that
Duke or the Company shall provide reasonable notice under the circumstances to
the other party prior to any such date), the Company and/or its wholly-owned
Subsidiaries shall be participating employers on behalf of their employees
(including any Continued Employees) who meet the requirements for eligibility
under the following Old Welfare Plans maintained by Duke: the Duke Energy
Medical, Dental, Cafeteria (FSP), Basic Life Insurance, Supplemental and
Dependent Life Insurance, Basic, Supplemental and Dependent Accidental Death and
Dismemberment Insurance, Business Travel Accident Insurance and Long-Term Care
Insurance Plans (each such Old Welfare Plan is herein referred to as a
"Continued Duke Welfare Plan"); provided, however, that retiree medical, dental
and life insurance coverages under the applicable Continued Duke Welfare Plans
shall not become applicable to an individual who either is not a Retained DEFS
Employee or fails to meet such requirements as Duke shall impose for such
coverages. Duke may terminate the participation by the Company and its
wholly-owned Subsidiaries in a particular Continued Duke Welfare Plan prior to
December 31, 2000, pursuant to clause (iii) of the preceding sentence only if
(1) Duke will be terminating such plan in its entirety as of the date designated
by Duke pursuant to such clause or (2) Duke has determined that such continued
participation by the Company and/or any of its wholly-owned Subsidiaries could
subject Duke or such plan to fines, penalties, excise taxes, loss of tax
deductions or other liabilities (other than liabilities for the benefits to be
provided under such plan). Without limiting the generality of the preceding
provisions of this Section 7.4(a), it is understood



                                      -14-
<PAGE>


and agreed that such provisions shall not override the provisions of Section
4.2(b) of Annex A to the Contribution Agreement. For purposes of applying
Section 4.5(c) of Annex A to the Contribution Agreement, the Continued Duke
Welfare Plans shall be deemed to be New Welfare Plans; provided, however, that
Eligible Expenses of a Retained DEFS Employee shall be determined without regard
to when such expenses are recorded by the applicable plan administrator or
reported to the Company.


          (b) Notwithstanding the provisions of Section 4.5(d) of Annex A to
the Contribution Agreement, for the period specified in Section 7.4(a) as it
applies to the Duke FSP, the Retained DEFS Employees shall continue to be
eligible, and the Transferred PGC Employees shall be eligible, to participate in
the Duke FSP. In the case of the Retained DEFS Employees, such continued
participation shall be based on their elections under the Duke FSP that are in
effect immediately prior to the date hereof (as such elections may be adjusted
from time to time in accordance with the terms of the Duke FSP). In the case of
the Transferred PGC Employees, the provisions of Section 4.5(d) of Annex A to
the Contribution Agreement shall be applied as if the Duke FSP were the New FSP
as defined therein, except that references therein to the Company shall be
deemed to refer to Duke; provided, however, that if the aggregate amount of the
transferred account balances of Transferred PGC Employees from the Phillips FSP
to the Duke FSP is negative, then the Company shall pay Phillips the amount of
such aggregate negative balance promptly following such account balance
transfer. The parties hereto agree and acknowledge that it is their intention
that the economic risks and benefits associated with calendar year 2000 (or any
portion thereof) participation in the Duke FSP by Retained DEFS Employees (both
before and after the date hereof), Transferred PGC Employees, and any other
employees of the Company and its Subsidiaries be borne or enjoyed, as the case
may be, by the Company. Accordingly, Duke and the Company agree that, as soon as
administratively feasible after all claims under the Duke FSP have been
processed for calendar year 2000 with respect to the employees of the Company
and its Subsidiaries, one such party shall make a payment to the other (as
appropriate) to ensure such result to the greatest extent possible.

          Section 7.5 Severance Benefits. (a) The Company or a Subsidiary of
the Company shall reimburse Phillips for the cash severance benefit paid by
Phillips or any Subsidiary of Phillips to certain of their employees in
accordance with the terms of Article I of Exhibit A to that certain Transition
Services Agreement between Phillips and the Company dated March 17, 2000.


          (b) Section 4.2(b) of Annex A to the Contribution Agreement shall
apply to each Retained DEFS Employee who is a TEPPCO Employee and who was
covered by the Change in Control Severance Plan immediately prior to the date
hereof; provided, however, that (i) the Company shall not have any reimbursement
obligation to Duke under such Section 4.2(b) with respect to the cash severance
benefit paid to any such employee and (ii) Duke shall not have any reimbursement
obligation to the Company under such Section 4.2(b) for any extended coverage
under a welfare benefit plan.

          (c) The provisions of this Section 7.5(c) shall not apply with
respect to any Retained DEFS Employee who is a TEPPCO Employee. Duke shall
reimburse the Company or a Subsidiary of the Company for the severance benefit
paid under the DEFS Severance Plan to any



                                      -15-
<PAGE>


Retained DEFS Employee who receives notice from the Company or a Subsidiary of
the Company on or about the date hereof that such individual's employment will
be terminated in connection with (and in any event within 30 days after) the
closing of the transactions contemplated under the Contribution Agreement. On or
about the date hereof, the Company and its Subsidiaries shall also notify
certain Retained DEFS Employees selected by the Company in its sole discretion
that such individuals will be requested to perform services for the Company or a
Subsidiary of the Company on only a transitional basis. Duke shall reimburse the
Company or a Subsidiary of the Company for the severance benefit paid under the
DEFS Severance Plan to any Retained DEFS Employee who receives the notice
described in the preceding sentence provided that the termination of such
individual's employment from the Company and its Affiliates occurs within six
months of the date hereof (or within nine months of the date hereof in the case
of such a Retained DEFS Employee who is an accountant).

          Section 7.6 Miscellaneous. The reference in Section 2.3 of Annex A to
the Contribution Agreement to Section 6.1 of the Governance Agreement shall be
deemed to refer to Section 6.1 of the Governance Agreement as in effect
immediately before the termination of the Governance Agreement. All references
in Sections 3.1, 4.1, 4.5(a), 4.5(b)(i)(A), 4.5(b)(ii)(I), 4.5(b)(iii)(x) and
the last sentence of Section 4.5(b) of Annex A to the Contribution Agreement to
the "Closing Date" shall be deemed to refer to the day after the Closing Date.

inconvenient forum to the maintenance of such action or proceeding. The parties
hereto further agree, to the extent permitted by law, that final and
unappealable judgment against any of them in any action or proceeding
contemplated above shall be conclusive and may be enforced in any other
jurisdiction within or outside the United States by suit on the judgment, a
certified copy of which shall be conclusive evidence of the fact and amount of
such judgment.

          (c) To the extent that any party hereto has or hereafter may acquire
any immunity from jurisdiction of any court or from any legal process (whether
through service or notice,



                                      -16-
<PAGE>


attachment prior to judgment, attachment in aid of execution, execution or
otherwise) with respect to itself or its property, each party hereto hereby
irrevocably waives such immunity in respect of its obligations with respect to

          Section 8.4 Expenses. Except as set forth in this Agreement, whether

form of payment of such price or prices (which may be cash, property or rights,
including securities of the same or another corporation or other entity) for
which, the period or periods within which and the terms and conditions upon
which the shares of such series shall be redeemed or purchased, in whole or in

specified event or events, into shares of any other class or classes or any
other series of the same or any other class or classes of stock, or any other
security, of the Corporation, or any other corporation or other entity, and the

applicable thereto, and all other terms and conditions upon which such

                  (j)    the voting rights, if any, of the holders of shares of
the series.

            Section 4.3. Common Stock. The Common Stock shall be subject to the
express terms of the Preferred Stock and any series thereof. The holders of
shares of Common Stock shall be entitled to one vote for each such share upon
all proposals on which the holders of Common Stock are entitled to vote and the
Common Stock shall vote together as a single class. Except as otherwise provided
by law or by the resolution or resolutions adopted by the Board designating the
rights, powers and preferences of any series of Preferred Stock, the holders of
Common Stock shall have the exclusive right to vote for the members of the Board
(the "Directors") and for all other purposes. The number of authorized shares of
Preferred Stock may be increased or decreased (but not below the number of
shares thereof then outstanding) by the affirmative vote of the holders of a
majority of the outstanding Common Stock, without a vote of the holders of the
Preferred Stock, or of any series thereof, unless a vote of any such holders is
required pursuant to any Preferred Stock Designation. The Corporation shall be
entitled to treat the Person in which name any share of its stock is registered
as the owner thereof for all purposes and shall not be bound to recognize any
equitable or other claim to, or interest in, such share on the part of any other
person, whether or not the Corporation shall have notice thereof, except as
expressly provided by applicable law.

extent that the Bylaws shall so require, the election of the Directors need not
be by written ballot.

                  AMENDMENT OF CERTIFICATE OF INCORPORATION

            Except as set forth in Article VI, Article X and Article XII hereof,
the Corporation reserves the right at any time and from time to time to amend,
alter, change or repeal any provision contained in this Certificate of
Incorporation, and any other provisions authorized by the laws of the State of
Delaware at the time in force may be added or inserted, in the manner now or
hereafter prescribed by law; and, except as set forth in Article XI, all rights,
preferences and privileges of whatsoever nature conferred upon stockholders,
Directors or any other persons whomsoever by and pursuant to this Certificate of
Incorporation in its present form or as hereafter amended are granted subject to

                      STOCKHOLDER ACTION BY WRITTEN CONSENT

            Prior to the first date (the "Trigger Date") upon which Duke is not
the holder of record (directly or through its subsidiaries) of a majority of the
outstanding voting stock of the Corporation entitled to vote generally in the
election of directors, any action required or permitted to be taken by the
stockholders of the Corporation may be taken without a meeting if a consent in
writing, setting forth the action so taken, is signed by the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting at which all shares
entitled to vote thereon were present and voted. On and after the Trigger Date,
any action required or permitted to be taken by the stockholders of the
Corporation must be taken at a duly held annual or special meeting of
stockholders and may not be taken by any consent in writing of such
stockholders.

                                   ARTICLE IX
                          DELAWARE ANTITAKEOVER STATUTE

            The provisions of Section 203 of the Delaware General Corporation
Law shall not be applicable to the Corporation.

                                    ARTICLE X
                                  ANTI-DILUTION

            At any time following the initial offering of shares of Common Stock
in a transaction registered under the Securities Act of 1933, as amended, if the
Corporation offers or issues additional shares of Common Stock or additional
shares of any other previously issued and outstanding capital stock in a public
offering, then, so long as Duke and Phillips Petroleum Company, a Delaware
corporation ("Phillips"), each owns at least 20%, directly or indirectly, of all
outstanding Common Stock, then each of Duke and Phillips shall have the
opportunity to



                                      -4-
<PAGE>


subscribe for and purchase such number of shares of Common Stock or such other
capital stock, as the case may be, such that the percentage ownership (direct or
indirect) of the total issued and outstanding Common Stock or such other capital
stock, as the case may be, of such party following the offering or issuance
remains equal to such party's percentage ownership (direct or indirect) of the
issued and outstanding Common Stock or such other capital stock, as the case may
be, immediately prior to the offering or issuance; provided, however, that
neither Duke nor Phillips shall have the right or opportunity hereunder to
purchase any additional Common Stock in connection with the issuance by the
Corporation of any Common Stock or options, warrants or other similar securities
in respect of Common Stock pursuant to a compensation or benefit plan or program
for officers or employees of the Corporation that has been approved by the Board
in accordance with the Bylaws. So long as Duke and Phillips each owns at least
20%, directly or indirectly, of all outstanding Common Stock, then any proposed
amendment to this Article X shall require the consent of Duke and Phillips.

                                   ARTICLE XI
                       LIMITED LIABILITY; INDEMNIFICATION

            Section 11.1. Limited Liability of Directors. A Director shall not
be personally liable to the Corporation or its stockholders for monetary damages
for breach of fiduciary duty as a Director, except, if required by the DGCL, as
amended from time to time, for liability (a) for any breach of the Director's
duty of loyalty to the Corporation or its stockholders, (b) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (c) under Section 174 of the DGCL or (d) for any transaction
from which the Director derived an improper personal benefit. Neither the
amendment nor repeal of this Section 11.1 shall eliminate or reduce the effect
of this Section 11.1 in respect of any matter occurring, or any cause of action,
suit or claim that, but for this Section 11.1, would accrue or arise, prior to
such amendment or repeal.

            Section 11.2. Indemnification and Insurance.
                          -----------------------------

                  (a) Right to Indemnification. Each person who was or is made a
party to or is threatened to be made a party to or is involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter, a "proceeding"), by reason of the fact that such person, or a
person of whom such person is the legal representative, is or was a Director or
officer of the Corporation or is or was serving at the request of the
Corporation as a Director, officer, employee or agent of another corporation or
of a partnership, joint venture, trust or other enterprise, including service
with respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a Director, officer, employee or agent
or in any other capacity while serving as a Director, officer, employee or
agent, shall be indemnified and held harmless by the Corporation to the fullest
extent authorized by the DGCL, as the same exists or may hereafter be amended
(but, in the case of any such amendment, to the fullest extent permitted by law,
only to the extent that such amendment permits the Corporation to provide
broader indemnification rights than said law permitted the Corporation to
provide prior to such amendment), against all expense, liability and loss
(including, without limitation, attorneys' fees, judgments, fines, amounts paid
or to be paid in settlement and excise taxes or penalties arising under the
Employment Retirement Income Security Act of 1974, as in effect from time to
time) reasonably incurred or suffered by such person in connection therewith,
and



                                      -5-
<PAGE>


such indemnification shall continue as to a person who has ceased to be a
Director, officer, employee or agent and shall inure to the benefit of such
person's heirs, executors and administrators; PROVIDED, HOWEVER, that, except as
provided in paragraph (b) hereof, the Corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board. The right to indemnification conferred in this Section
11.2 shall be a contract right and shall include the right to have the
Corporation pay the expenses incurred in defending any such proceeding in
advance of its final disposition, any advance payments to be paid by the
Corporation within 20 calendar days after the receipt by the Corporation of a
statement or statements from the claimant requesting such advance or advances
from time to time; PROVIDED, HOWEVER, that, if and to the extent the DGCL
requires, the payment of such expenses incurred by a Director or officer in such
person's capacity as a Director or officer (and not in any other capacity in
which service was or is rendered by such person while a Director or officer
including, without limitation, service to an employee benefit plan) in advance
of the final disposition of a proceeding shall be made only upon delivery to the
Corporation of an undertaking, by or on behalf of such Director or officer, to
repay all amounts so advanced if it shall ultimately be determined that such
Director or officer is not entitled to be indemnified under this Section 11.2 or
otherwise. The Corporation may, to the extent authorized from time to time by
the Board, grant rights to indemnification, and rights to have the Corporation
pay the expenses incurred in defending any proceeding in advance of its final
disposition, to any employee or agent of the Corporation to the fullest extent
of the provisions of this Article XI with respect to the indemnification and
advancement of expenses of Directors and officers of the Corporation.

                  (b) Right of Claimant to Bring Suit. If a claim under
paragraph (a) of this Section is not paid in full by the Corporation within 30
calendar days after a written claim has been received by the Corporation, the
claimant may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim and, if successful in whole or in part,
the claimant shall be entitled to be paid also the expense of prosecuting such
claim. It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in defending any proceeding in advance of
its final disposition where the required undertaking, if any is required, has
been tendered to the Corporation) that the claimant has not met the standard of
conduct which makes it permissible under the DGCL for the Corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Corporation. Neither the failure of the Corporation
(including its Board, independent legal counsel or its stockholders) to have
made a determination prior to the circumstances that the claimant has met the
applicable standard of conduct set forth in the DGCL, nor an actual
determination by the Corporation (including its Board, independent legal counsel
or its stockholders) that the claimant has not met such applicable standard of
conduct, shall be a defense to the action or create a presumption that the
claimant has not met the applicable standard of conduct.

                  (c) Non-Exclusivity of Rights. The right to indemnification
and the payment of expenses incurred in defending a proceeding in advance of its
final disposition conferred in this Section 11.2 shall not be exclusive of any
other right which any person may have or hereafter acquire under any statute,
provision of the Certificate of Incorporation, Bylaw, agreement, vote of
stockholders or disinterested Directors or otherwise. No repeal or



                                      -6-
<PAGE>


modification of this Article XI shall in any way diminish or adversely affect
the rights of any Director, officer, employee or agent of the Corporation
hereunder in respect of any occurrence or matter arising prior to any such
repeal or modification.

                  (d) Insurance. The Corporation may maintain insurance, at its
expense, to protect itself and any Director, officer, employee or agent of the
Corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability or loss, whether or not the
Corporation would have the power to indemnify such person against such expense,
liability or loss under the DGCL.

                  (e) Severability. If any provision or provisions of this
Article XI shall be held to be invalid, illegal or unenforceable for any reason
whatsoever: (i) the validity, legality and enforceability of the remaining
provisions of this Article XI (including, without limitation, each portion of
any paragraph of this Article XI containing any such provision held to be
invalid, illegal or unenforceable, that is not itself held to be invalid,
illegal or unenforceable) shall not in any way be affected or impaired thereby;
and (ii) to the fullest extent possible, the provisions of this Article XI
(including, without limitation, each such portion of any paragraph of this
Article XI containing any such provision held to be invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested
by the provision or provisions held invalid, illegal or unenforceable.

                                   ARTICLE XII
                        BUSINESS OPPORTUNITIES AGREEMENT

            Section 12.1. Scope of Business of the Corporation and its
Subsidiaries. The Corporation hereby renounces any interest or expectancy in any
business opportunity, transaction or other matter (each, a "Business Activity")
in which Duke engages or seeks to engage that does not consist exclusively of
the Designated Business.

            Section 12.2. Corporate Opportunities.
                          -----------------------

                  (a) In recognition that Duke is currently (at least
indirectly), and in anticipation that Duke will remain, a substantial
stockholder of the Corporation, and in anticipation that the Corporation and
Duke may engage in the same or similar activities or lines of business and have
an interest in the same or similar areas of business, and in recognition of the
benefits to be derived by the Corporation through its continued contractual,
corporate and business relations with Duke (including services of employees,
officers and directors of Duke as Directors and officers of the Corporation),
the provisions of this Article XII are set forth to regulate and define the
conduct of certain affairs of the Corporation as they may involve Duke and its
employees, officers and directors, and the powers, rights, duties, liabilities,
interests and expectancies of the Corporation in connection therewith.

                  (b) Duke shall have the right to engage (and shall have no
duty to refrain from engaging) in the same or similar activities or lines of
business as the Corporation, and the Corporation shall not be deemed to have any
interest or expectancy, and hereby renounces any interest or expectancy, in any
Business Activity, provided that such Business Activity is conducted by Duke in
accordance with the standards set forth in Section 12.3 hereof.



                                      -7-
<PAGE>

Neither Duke nor any employee, officer, director or agent thereof shall be
liable to the Corporation or its stockholders for breach of any fiduciary or
other duty by reason of any such Business Activity of Duke or of such person's
participation therein. In the event that Duke acquires knowledge of a potential
Business Activity, unless such Business Activity is pursued in violation of the
standards set forth in Section 12.3 hereof, Duke shall have no duty to
communicate or offer to the Corporation the opportunity to participate in such
Business Activity and shall not be liable to the Corporation or its stockholders
for breach of any fiduciary duty as a stockholder of the Corporation by reason
of the fact that Duke conducts, pursues or acquires such Business Activity for
itself, directs such Business Activity to another Person or does not communicate
information regarding such Business Activity to the Corporation, and no officer,
director, employee or other agent of Duke who serves as a Director or officer of
the Corporation or of any subsidiary of the Corporation shall have any duty to
communicate or offer the opportunity to participate in such Business Activity to
the Corporation or any liability to the Corporation or its stockholders for
breach of any fiduciary duty as a Director or officer of the Corporation by
reason of the fact that Duke conducts, pursues or acquires such Business
Activity for itself, directs such Business Activity to another Person or does
not communicate information regarding such Business Activity to the Corporation.

            Section 12.3. Standards for Separate Conduct of Business. In the
event that Duke or any Director or officer of the Corporation who is also a
director, officer, employee or agent of Duke acquires knowledge of a potential
Business Activity, Duke, or any such person on behalf of Duke, may pursue such
Business Activity, and such pursuit shall be in accordance with the standards
set forth in this Section 12.3, if (i) such knowledge was acquired by Duke or
any such person other than through disclosure of information by or on behalf of
a Director, officer, employee or agent of the Corporation in or during the
course of such person's relationship with the Corporation and other than solely
in, and as a direct result of, such person's service as a Director or officer of
the Corporation (it being understood that if the opportunity to pursue such
Business Activity is separately identified by Duke or one of its officers,
directors, employees or agents or separately presented to Duke or one of its
officers, directors, employees or agents, Duke, or any such officer, director,
employee or agent on behalf of Duke, shall be free to pursue such opportunity
even if it also came to the attention of another officer, director, employee or
agent of Duke as a result of and in his or her capacity as a Director or officer
of the Corporation), and (ii) such Business Activity is developed and pursued
solely through the use of personnel and assets of Duke (including such person in
his or her capacity as a director, officer, employee or agent of Duke). The
Corporation shall renounce any interest or expectancy in any Business Activity
that is conducted by Duke or its officers, directors, employees or agents on
behalf of Duke in accordance with the foregoing standards. Nothing in this
Article XII shall allow any Director designated by Duke to pursue a Business
Activity in the Designated Business solely for his or her personal benefit (as
opposed to for the benefit of Duke).

            Section 12.4. Consent. Any Person purchasing or otherwise
acquiring any interest in shares of the capital stock of the Corporation
shall be deemed to have consented to these provisions.

                           AMENDED AND RESTATED BYLAWS
                                       OF
                     DUKE ENERGY FIELD SERVICES CORPORATION


            The original Bylaws of Duke Energy Field Services Corporation
(formerly known as DEFS Holding Corp.) (the "Corporation") were adopted by the
board of directors of the Corporation (the "Board") on December 8, 1999.

            These Amended and Restated Bylaws have been declared advisable by
the Board, duly adopted by the stockholders of the Corporation and duly executed
and acknowledged by the officers of the Corporation in accordance with Section
109 of the General Corporation Law of the State of Delaware ("DGCL").

            The text of the Bylaws of the Corporation is hereby amended and
restated to read in its entirety as follows:

                                   ARTICLE I
                               OFFICES AND RECORDS

            The Corporation shall maintain a registered office in Delaware and
may maintain such other offices and keep its books, documents and records at
such places within or without Delaware as may, from time to time, be designated
by the Board.

                                   ARTICLE II
                                  STOCKHOLDERS

            Section 2.1.  Annual Meeting.  The annual meeting of the
stockholders of the Corporation shall be held on such date and at such time
as may be fixed by resolution of the Board.

            Section 2.2.  Special Meeting. Except as otherwise required by law
and subject to the rights of the holders of any class or series of stock having
a preference over the Common Stock, as defined in the Certificate of
Incorporation of the Corporation (the "Certificate of Incorporation"), as to
dividends or upon liquidation, special meetings of the stockholders of the
Corporation for any purpose or purposes may be called only by:

            (a)   the Board pursuant to a resolution stating the purpose or
purposes thereof approved by a majority of the Board, or

            (b)   the Chairman of the Board.

No business other than that stated in the notice shall be transacted at any
special meeting.

            Section 2.3.  Place of Meeting. The Board or the Chairman of the
Board, as the case may be, may designate the place of meeting for any annual
meeting or for any special meeting of the stockholders. If no designation is so
made, the place of meeting shall be the principal office of the Corporation.


<PAGE>


            Section 2.4.  Notice of Meeting. Written or printed notice, stating
the place, day and hour of the meeting and, in the case of a special meeting,
the purpose or purposes for which the meeting is called, shall be delivered by
the Corporation not less than ten calendar days nor more than 60 calendar days
before the date of the meeting, either personally or by mail, to each
stockholder of record entitled to vote at such meeting. Holders of Preferred
Stock, as defined in the Certificate of Incorporation, shall not be entitled to
receive notice of any meeting of stockholders at which they are not entitled to
vote. If mailed, such notice shall be deemed to be delivered when deposited in
the United States mail with postage thereon prepaid, addressed to the
stockholder at such person's address as it appears on the stock transfer books
of the Corporation. Only such business shall be conducted at a special meeting
of stockholders as shall have been included in the Corporation's notice of
meeting. Meetings may be held without notice if all stockholders entitled to
vote are present, or if notice is waived by those not present in accordance with
Section 6.4 of these Bylaws. Any previously scheduled meeting of the
stockholders may be postponed, and any special meeting of the stockholders may
be canceled, by resolution of the Board upon public notice given prior to the
date previously scheduled for such meeting of stockholders.

            Section 2.5.  Quorum and Adjournment; Voting. Except as otherwise
provided by law or by the Certificate of Incorporation, the holders of a
majority of the voting power of all outstanding shares of the Corporation
entitled to vote generally in the election of Directors (as hereinafter defined)
(the "Voting Stock"), represented in person or by proxy, shall constitute a
quorum at a meeting of stockholders, except that when specified business is to
be voted on by a class or series of stock voting as a class, the holders of a
majority of the shares of such class or series shall constitute a quorum of such
class or series for the transaction of such business. The chairman of the
meeting or a majority of the shares so represented may adjourn the meeting from
time to time, whether or not there is such a quorum. No notice of the time and
place of adjourned meetings need be given except as required by law. The
stockholders present at a duly called meeting at which a quorum is present may
continue to transact business until adjournment, notwithstanding the withdrawal
of enough stockholders to leave less than a quorum.

            Section 2.6.  Proxies.  At all meetings of stockholders, a
stockholder may vote by proxy executed in writing (or in such other manner
permitted by the DGCL) by the stockholder or by such person's duly authorized
attorney-in-fact.

            Section 2.7.  Notice of Stockholder Business and Nominations.

            (a)    Annual Meetings of Stockholders.

                   (i)    Nominations of persons for election to the Board and
the proposal of business to be considered by the stockholders may be made at an
annual meeting of stockholders (A) pursuant to the Corporation's notice of
meeting in accordance with Section 2.4 of these Bylaws, (B) by or at the
direction of the Board, or (C) by any stockholder of the Corporation who was a
stockholder of record at the time the notice provided for in this Bylaw was
delivered, who is entitled to vote at the meeting and who complies with the
notice procedures set forth in this Bylaw.

                   (ii)   For nominations or other business to be properly
brought before an annual meeting by a stockholder pursuant to clause (C) of
Section 2.7(a)(i) hereof, the stockholder must have given timely notice thereof
in writing to the Secretary of the Corporation and such other business must
otherwise be a proper matter for stockholder action. To be timely, a
stockholder's notice shall be delivered to the Secretary at the principal
executive offices of the Corporation not later than the close of business on the
90th calendar day nor earlier than the close of business on the 120th calendar
day prior to the first anniversary of the preceding year's annual meeting;
provided, however, that in the event that the date of the annual meeting is more
than 30 calendar days before or more than 60 calendar days after such
anniversary date, notice by the stockholder to be timely must be so delivered
not earlier than the close of business on the 120th calendar day prior to such
annual meeting and not later than the close of business on the later of the 90th
calendar day prior to such annual meeting or the 10th calendar day following the
calendar day on which public announcement of the date of such meeting is first
made by the Corporation. In no event shall the public announcement of an
adjournment of an annual meeting commence a new time period for the giving of a
stockholder's notice as described above. Such stockholder's notice shall set
forth (A) as to each person whom the stockholder proposes to nominate for
election or reelection as a Director, all information relating to such person
that is required to be disclosed in solicitations of proxies for election of
Directors in an election contest, or is otherwise required, in each case
pursuant to Regulation 14A under the Securities Exchange Act of 1934, as amended
(the "Exchange Act"), and Rule 14a-11 thereunder (including such person's
written consent to being named in the proxy statement as a nominee and to
serving as a member of the Board (a "Director") if elected); (B) as to any other
business that the stockholder proposes to bring before the meeting, a brief
description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting and any material interest in
such business of such stockholder and the beneficial owner, if any, on whose
behalf the proposal is made; and (C) as to the stockholder giving the notice and
the beneficial owner, if any, on whose behalf the nomination or proposal is
made, (1) the name and address of such stockholder, as they appear on the
Corporation's books, and of such beneficial owner and (2) the class and number
of shares of the Corporation which are owned beneficially and of record by such
stockholder and such beneficial owner.

                   (iii)  Notwithstanding anything in the second sentence of
paragraph (a)(ii) of this Bylaw to the contrary, in the event that the number of
Directors to be elected to the Board is increased and there is no public
announcement by the Corporation naming all of the nominees for Director or
specifying the size of the increased Board at least 100 calendar days prior to
the first anniversary of the preceding year's annual meeting, a stockholder's
notice required by this Bylaw shall also be considered timely, but only with
respect to nominees for any new positions created by such increase, if it shall
be delivered to the Secretary at the principal executive offices of the
Corporation not later than the close of business on the tenth calendar day
following the day on which such public announcement is first made by the
Corporation.

            (b)    Special Meetings of the Stockholders. Only such business
shall be conducted at a special meeting of stockholders as shall have been
brought before the meeting pursuant to the Corporation's notice of meeting under
Section 2.4 of these Bylaws. Nominations of persons for election to the Board
may be made at a special meeting of stockholders at which Directors are to be
elected pursuant to the Corporation's notice of meeting (i) by or at the
direction of the Board, (ii) provided that the Board has determined that
Directors shall be elected




                                      -3-


<PAGE>


at such meeting, by any stockholder of the Corporation who is a stockholder of
record at the time of giving of notice provided for in this Bylaw, who shall be
entitled to vote at the meeting and who complies with the notice procedures set
forth in this Bylaw. In the event the Corporation calls a special meeting of
stockholders for the purpose of electing one or more Directors to the Board, any
stockholder may nominate a person or persons (as the case may be) for election
to such position(s) as specified in the Corporation's notice of meeting pursuant
to clause (ii) if the stockholder's notice required by paragraph (a)(ii) of this
Bylaw shall be delivered to the Secretary at the principal executive offices of
the Corporation not earlier than the close of business on the 120th calendar day
prior to such special meeting and not later than the close of business on the
later of the 90th calendar day prior to such special meeting or the tenth
calendar day following the day on which public announcement is first made of the
date of the special meeting and of the nominees proposed by the Board to be
elected at such meeting. In no event shall the public announcement of an
adjournment of a special meeting commence a new time period for the giving of a
stockholder's notice as described above.

            (c)    General.

                   (i)    Only such persons who are nominated in accordance with
the procedures set forth in this Bylaw shall be eligible to serve as Directors
and only such business shall be conducted at a meeting of stockholders as shall
have been brought before the meeting in accordance with the procedures set forth
in this Bylaw. Except as otherwise provided by law, the Certificate of
Incorporation or these Bylaws, the chairman of the meeting shall have the power
and duty to determine whether a nomination or any business proposed to be
brought before the meeting was made or proposed, as the case may be, in
accordance with the procedures set forth in this Bylaw and, if any proposed
nomination or business in not in compliance with this Bylaw, to declare that
such defective proposal or nomination shall be disregarded.

                   (ii)   For purposes of this Bylaw, "public announcement"
shall mean disclosure in a press release reported by the Dow Jones News Service,
Associated Press or comparable national news service or in a document publicly
filed by the Corporation with the Securities and Exchange Commission pursuant to
Section 13, 14 or 15(d) of the Exchange Act.

                   (iii)  Notwithstanding the foregoing provisions of this
Bylaw, a stockholder shall also comply with all applicable requirements of the
Exchange Act and the rules and regulations thereunder with respect to the
matters set forth in this Bylaw. Nothing in this Bylaw shall be deemed to affect
any rights (A) of stockholders to request inclusion of proposals in the
Corporation's proxy statement pursuant to Rule 14a-8 under the Exchange Act or
(B) of the holders of any series of Preferred Stock to elect Directors under an
applicable Preferred Stock Designation (as defined in the Certificate of
Incorporation).

            Section 2.8.  Procedure for Election of Directors; Required Vote.
Election of Directors at all meetings of the stockholders at which Directors are
to be elected shall be by ballot, and, subject to the rights of the holders of
any series of Preferred Stock to elect Directors under an applicable Preferred
Stock Designation, a plurality of the votes cast thereat shall elect Directors.
Except as otherwise provided by law, the Certificate of Incorporation, Preferred
Stock Designation or these Bylaws, in all matters other than the election of
Directors, the affirmative

<PAGE>


vote of a majority of the voting power of the shares present in person or
represented by proxy at the meeting and entitled to vote on the matter shall be
the act of the stockholders.

            Section 2.9.  Inspectors of Elections; Opening and Closing the
Polls. The Board by resolution shall appoint, or shall authorize an officer of
the Corporation to appoint, one or more inspectors, which inspector or
inspectors may include individuals who serve the Corporation in other
capacities, including, without limitation, as officers, employees, agents or
representatives, to act at the meetings of stockholders and make a written
report thereof. One or more persons may be designated as alternate inspector(s)
to replace any inspector who fails to act. If no inspector or alternate has been
appointed to act or is able to act at a meeting of the stockholders, the
chairman of the meeting shall appoint one or more inspectors to act at the
meeting. Each inspector, before discharging such person's duties, shall take and
sign an oath faithfully to execute the duties of inspector with strict
impartiality and according to the best of such person's ability. The
inspector(s) shall have the duties prescribed by law. The chairman of the
meeting shall fix and announce at the meeting the date and time of the opening
and the closing of the polls for each matter upon which the stockholders will
vote at a meeting.

            Section 2.10. Conduct of Meetings. The Board may to the extent not
prohibited by law adopt such rules and regulations for the conduct of meetings
of stockholders as it shall deem appropriate. Except to the extent inconsistent
with such rules and regulations as adopted by the Board, the chairman of any
meeting of stockholders shall have the right and authority to prescribe such
rules, regulations and procedures and to do all such acts as, in the judgment of
such chairman, are appropriate for the proper conduct of the meeting. Such
rules, regulations or procedures, whether adopted by the Board or prescribed by
the chairman of the meeting, may to the extent not prohibited by law include,
without limitation, the following: (a) the establishment of an agenda or order
of business for the meeting; (b) rules and procedures for maintaining order at
the meeting and the safety of those present; (c) limitations on attendance at or
participation in the meeting to stockholders of record of the Corporation, their
duly authorized and constituted proxies or such other persons as the chairman of
the meeting shall determine; (d) restrictions on entry to the meeting after the
time fixed for the commencement thereof; and (e) limitations on the time
allotted to questions or comments by participants. The date and time of the
opening and closing of the polls for each matter upon which the stockholders
will vote at a meeting shall be announced at the meeting by the person presiding
over the meeting. Unless and to the extent determined by the Board or the
chairman of the meeting, meetings of stockholders shall not be required to be
held in accordance with the rules of parliamentary procedure.


                                   ARTICLE III
                                    THE BOARD

            Section 3.1.  General Powers. The business and affairs of the
Corporation shall be managed under the direction of the Board. In addition to
the powers and authorities expressly conferred upon the Board by these Bylaws,
the Board may exercise all such powers of the Corporation and do all such lawful
acts and things as are not by statute, by the Certificate of Incorporation or by
these Bylaws required to be exercised or done by the stockholders. Except as
provided in the following sentence with respect to actions with respect to the
matters set forth in Annex A hereto, all decisions of the Board shall require
the affirmative vote of a majority of




                                      -5-


<PAGE>


the Directors present at a meeting at which a quorum is present. So long as each
of Phillips Petroleum Company, a Delaware corporation ("Phillips"), and Duke
Energy corporation, a North Carolina corporation ("Duke"), owns, directly or
indirectly, at least 20% of the Common Stock, no action shall be taken by the
Board with respect to the matters set forth in Annex A hereto without the prior
approval of at least eight of the 11 Directors of the Board.

            Section 3.2.  Number; Qualifications and Tenure. The number of the
Directors shall be 11. A Director need not be a stockholder of the Corporation.

            Section 3.3.  Regular Meetings. The Board shall meet at least
quarterly. The Board may, by resolution and notice to each of the Directors,
provide the time and place for the holding of additional regular meetings
without other notice than such resolution and notice to the Directors.

            Section 3.4.  Special Meetings. A special meeting of the Board may
be called at any time on two Business Days' prior notice at the request of (a)
the Chairman of the Board or (b) any four Directors. As used in these Bylaws,
the term "Business Day" shall mean any day on which banks are generally open to
conduct business in the State of New York. The place of any special meeting
shall be the corporate headquarters of the Corporation unless otherwise agreed
by a majority of the Directors.

            Section 3.5.  Notice. Written notice of all regular meetings of the
Board must be given to all Directors at least 15 days prior to the regular
meeting of the Board and two Business Days prior to any special meeting of the
Board. All notices and other communications to be given to Directors shall be
sufficiently given for all purposes hereunder if in writing and delivered by
hand, courier or overnight delivery service or three days after being mailed by
certified or registered mail, return receipt requested, with appropriate postage
prepaid, or when received in the form of a telegram or facsimile, and shall be
directed to the address or facsimile number as such Director shall designate by
notice to the Corporation. Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the Board need be specified in the
notice of such meeting, except for amendments to these Bylaws, as provided under
Article VIII. A meeting may be held at any time without notice if all the
Directors are present or if those not present waive notice of the meeting in
accordance with Section 6.4.

            Section 3.6.  Action by Consent of Board. To the extent permitted by
applicable law, the Board and any committee thereof may act without a meeting so
long as all members of the Board or committee shall have executed a written
consent with respect to any Board action taken in lieu of a meeting.

            Section 3.7.  Conference Telephone Meetings. Members of the Board or
any committee thereof may participate in a meeting of the Board or such
committee by means of conference telephone or similar communications equipment
by means of which all persons participating in the meeting can hear each other,
and such participation in a meeting shall constitute presence in person at such
meeting.

            Section 3.8.  Quorum. At least six Directors, present in person,
participating in accordance with Section 3.7 or represented by proxy, shall
constitute a quorum for the




                                      -6-


<PAGE>


transaction of business, but if at any meeting of the Board there shall be less
than a quorum present, a majority of the Directors present may adjourn the
meeting from time to time without further notice. Subject to the supermajority
voting provisions of Section 3.1, the act of the majority of the Directors
present at a meeting at which a quorum is present shall be the act of the Board.
The Directors present at a duly organized meeting may continue to transact
business until adjournment, notwithstanding the withdrawal of enough Directors
to leave less than a quorum.

            Section 3.9.  Vacancies; Increases in the Number of Directors.
Vacancies and newly created directorships resulting from any increase in the
authorized number of Directors may be filled by a majority of the Directors then
in office, although less than a quorum, or a sole remaining Director; and any
Director so chosen shall hold office until the next annual election and until
his successor shall be duly elected and shall qualify, unless sooner displaced.

            Section 3.10. Executive and Other Committees. (a) The Board may
establish committees of the Board and, to the extent not inconsistent with the
supermajority voting provisions of Section 3.1, may delegate certain of its
responsibilities to such committees, provided that so long as each of Phillips
and Duke owns, directly or indirectly, at least 20% of the Common Stock, each
committee of the Board, other than the audit committee, shall include at least
one Director designated by Phillips who is not an Independent Director (as
hereinafter defined) and one Director designated by Duke who is not an
Independent Director.

                   (b)    The Board shall have an audit committee comprised of
three Independent Directors, which audit committee shall establish a written
audit committee charter in accordance with the rules of the New York Stock
Exchange, Inc. (the "NYSE"), as amended from time to time. "Independent
Director" shall mean a Director meeting the independence and experience
requirements, as set forth by the NYSE as of ______________, 2000 for membership
on the audit committee of the Board, with respect to each of Phillips, Duke and
the Corporation.

                   (c)    Unless the Board shall otherwise provide, a majority
of any committee may fix the time and place of its meetings and, subject to the
supermajority voting provisions of Section 3.1, may determine its action. Notice
of such meetings shall be given to each member of the committee in the manner
provided for in Section 3.5 of these Bylaws. Subject to Section 3.10(a), the
Board shall have power at any time to fill vacancies in, to change the
membership of, or to dissolve any such committee. Nothing herein shall be deemed
to prevent the Board from appointing one or more committees consisting in whole
or in part of persons who are not Directors; provided, however, that no such
committee shall have or may exercise any authority of the Board.

            Section 3.11. Removal.  Any Director or the entire Board may be
removed, with or without cause, by the holders of a majority of the Voting
Stock.

            Section 3.12. Records. The Board shall cause to be kept a record
containing the minutes of the proceedings of the meetings of the Board and of
the stockholders, appropriate stock books and registers and such books of
records and accounts as may be necessary for the proper conduct of the business
of the Corporation.

                                   ARTICLE IV
                                    OFFICERS

            Section 4.1.  Elected Officers. The executive officers of the
Corporation shall be selected by, and serve at the pleasure of, the Board. Such
officers shall have the authority and duties delegated to each of them,
respectively, by the Board from time to time. The elected officers of the
Corporation shall be a Chairman of the Board, a President, a Secretary, a
Treasurer, and such other officers (including, without limitation, Executive
Vice Presidents, Senior Vice Presidents and Vice Presidents) as the Board from
time to time may deem proper. The Chairman of the Board shall be chosen from
among the Directors. All officers elected by the Board shall each have such
powers and duties as generally pertain to their respective offices, subject to
the specific provisions of this Article IV. The Board or any committee thereof
may from time to time elect, or the Chairman of the Board may appoint, such
other officers (including one or more Vice Presidents, Controllers, Assistant

Vice President may execute bonds, contracts, deeds, leases and other instruments
to be made or executed for or on behalf of the Corporation. Subject to any
restrictions imposed by the Board, the Chairman of the Board, the President or

such consent, and may execute or cause to be executed in the name and on behalf
of the Corporation and under its corporate seal or otherwise, all such written
proxies or other instruments as he may deem necessary or proper in the premises.

                                OTHER AGREEMENTS

            Section 3.1 Special Buy-out Right. (a) Following the one year
anniversary of the consummation of the IPO, if a Phillips Veto occurs with
regard to different proposals proposed in good faith at three separate meetings
(with at least two months between the first and third meetings) of the
Corporation Board within any 18-month period, DENG shall have the right (the
"Buy-Out Right"), exercisable upon written notice (the "Buy-Out Notice") at any
time after the third such Phillips Veto, but not later than the thirtieth day
after the end of the eighteenth month after the occurrence of the first of the
three Phillips Vetoes that are the basis for the exercise of the Buy-Out Right,
to purchase all (but not less than all) of Phillips' Corporation Interest
pursuant to this Section 3.1. The Buy-Out Notice shall set forth the name of a
nationally recognized appraisal firm (which may be an investment banking,
accounting or other firm that performs appraisal and valuation services)
designated by DENG as its appraisal firm (the "Duke Appraiser").

            (b) Within 15 days from the date of receipt of the Buy-Out Notice,
PGCSI Parent shall notify DENG in writing of the name of an appraisal firm
(which may be an investment banking, accounting or other firm that performs
appraisal and valuation services) designated as PGCSI Parent's appraisal firm
(the "Phillips Appraiser"); PROVIDED, HOWEVER, that if Phillips fails to select
an appraisal firm, the Phillips Appraiser shall be Ernst & Young L.L.P.
(PROVIDED, FURTHER, that if Ernst & Young L.L.P. fails to accept the appointment
within 30 days from the date of PGCSI Parent's receipt of the Buy-Out Notice,
the Appraiser Committee shall consist solely of the Duke Appraiser). If
applicable, the Duke Appraiser and the Phillips Appraiser shall jointly choose a
third appraisal firm (which may be an investment banking, accounting or other
firm that performs appraisal and valuation services) within 15 days after the
appointment of the Phillips Appraiser (PROVIDED, HOWEVER, that if they fail to
select a third appraisal firm within 15 days after the appointment of the
Phillips Appraiser, such third firm (which shall be an investment banking,
accounting or other firm that performs appraisal and valuation services) will be
selected by the American Arbitration Association at the request of either party
within 10 days after such request) (the "Neutral Appraiser," and together with
the Duke Appraiser and the Phillips Appraiser, the "Appraiser Committee"). Once
the Appraiser Committee has been selected, each of DENG and PGCSI Parent shall
submit proposed Fair Market Values of Phillips' Corporation Interest to the
Appraiser Committee, together with any supporting documentation such Party deems
appropriate, as soon as practicable, but in no event earlier than 30 days after
the date of receipt of the Buy-Out Notice nor later than (i) 30 days after the
date of selection of the Neutral Appraiser, or (ii) in the event of the failure
of Ernst & Young L.L.P. to accept the appointment within the required time
period, 60 days from the date of PGCSI Parent's receipt of the Buy-Out Notice.
If either Party fails to submit its proposed Fair Market Value within the
required time period, the Fair Market Value proposed by the other Party
(assuming such other Party has submitted its proposed value within the required
time period) shall be deemed to be the Fair Market Value of Phillips'
Corporation Interest for purposes of this Section 3.1. If both Parties submit
their respective proposed values on a timely basis, the Appraiser Committee
shall determine, by majority vote, the Fair Market Value of Phillips'
Corporation Interest as of the date of the Buy-Out Notice as promptly as
possible (and in any event on or before the 30th day after submittal of the
competing proposals), which determination shall be final and binding on the
Parties. The cost of such appraisal shall be paid in equal portions by each of
DENG and PGCSI Parent. The Company shall provide to each of Duke and Phillips
and, if applicable, the Appraiser Committee, all information reasonably
requested by them.

            (c) The closing of DENG's acquisition of Phillips' Corporation
Interest shall be consummated on or before the 60th day after the determination
of the Fair Market Value in accordance with Section 3.1(b). The acquisition
shall be consummated at a closing held at the principal offices of the
Corporation (unless otherwise mutually agreed by DENG and PGCSI Parent) at which
time the purchase price, payable in the form of immediately available funds,
shall be delivered to PGCSI Parent, and PGCSI Parent shall deliver or cause to
be delivered to DENG (or, at DENG's option, to a designee of DENG designated by
DENG not less than five days prior to the closing) such transfer documentation
reasonably acceptable to DENG (or such designee) as shall be required to
evidence the transfer of Phillips' Corporation Interest, free and clear of all
liens and encumbrances, except those created under this Agreement.

                                   ARTICLE IV
                       LIQUIDITY AND TRANSFER RESTRICTIONS

            Section 4.1 Right of First Offer. If a Duke Shareholder or a
Phillips Shareholder (each, a "Shareholder") desires to Transfer all or any
portion of its Corporation Interest (other than pursuant to a registered public
offering) to a Person other than an Affiliate, then prior to effecting or making
such Transfer, the Person desiring to make such Transfer (a "Transferring
Entity") shall notify in writing the other Party or Parties that are not
Affiliates of the Transferring Entity (whether one or more, the
"Non-Transferring Entity") of the terms and conditions upon which it proposes to
effect such Transfer (which notice shall be herein referred to as a "Transfer
Notice" and shall include all material price and non-price terms and
conditions). The Non-Transferring Entity shall have the right to acquire all
(but not less than all) of the Corporation Interest that is the subject of the
Transfer Notice on the same terms and conditions as are set forth in the
Transfer Notice. The Non-Transferring Entity shall have 30 days following
delivery of the Transfer Notice during which to notify the Transferring Entity
whether or not it desires to exercise its right of first offer. If the
Non-Transferring Entity does not respond during the applicable period set forth
above for exercising its purchasing right under this Section 4.1, such
Non-Transferring Entity shall be deemed to have waived such right. If the
Non-Transferring Entity elects to purchase all, but not less than all, of the
Corporation Interest that is the subject of the Transfer Notice, the closing of
such purchase shall occur at the principal place of business of the Corporation
on the tenth day following the first date on which all applicable conditions
precedent have been satisfied or waived (but in no event shall such closing take
place later than the date that is 60 days (subject to extension for regulatory
approvals, but in no event more than 180 days) following the date on which the
Non-Transferring Entity agrees to purchase all of the Corporation Interest that
is the subject of the Transfer Notice). The Transferring Entity and the
purchasing Non-Transferring Entity agree to use commercially reasonable efforts
to cause any applicable conditions precedent to be satisfied as expeditiously as
possible. At the closing, (a) the Transferring Entity shall execute and deliver
to the purchasing Non-Transferring Entity (or, at the option of the
Non-Transferring Entity, to an Affiliate of the Non-Transferring Entity
designated by the Non-Transferring Entity not less than five days prior to the
closing) (i) an assignment of the Corporation Interest described in the Transfer
Notice, in form and substance reasonably acceptable to the purchasing
Non-Transferring Entity (or such Affiliate) and (ii) any other instruments
reasonably requested by the purchasing Non-Transferring Entity to give effect to
the purchase; and (b) the purchasing Non-Transferring Entity shall deliver to
the Transferring Entity the purchase price specified in the Transfer Notice in
immediately available funds or other consideration as specified in the Transfer
Notice. If the Non-Transferring Entity does



                                      -7-
<PAGE>


not elect to purchase the Corporation Interest pursuant to this Section 4.1, or
having elected to so purchase such Corporation Interests fails to do so within
the time period required by this Section 4.1, the Transferring Entity shall be
free for a period of 180 days after the expiration of the offer period referred
to above or the date of such failure, as applicable, to enter into a definitive
written agreement with an unaffiliated third party regarding the Transfer of its
Corporation Interest on terms and conditions that satisfy the following
criteria:

               (1) the amount of consideration to be paid by the purchasing
party may not be less than the consideration set forth in the Transfer Notice;

               (2) the form of consideration may not be materially different
from that set forth in the Transfer Notice, except to the extent any change in
the form of consideration makes the terms of the transaction less favorable
from the purchaser's standpoint; and

               (3) the terms and conditions set forth in such definitive written
agreement, when considered together with the form and amount of consideration to
be paid by such purchasing party, may not render the terms of such transaction,
taken as a whole, materially inferior (to the Transferring Entity from an
economic standpoint) to those set forth in the Transfer Notice (it being agreed
that the granting by the Transferring Entity of representations, warranties and
indemnities with respect to the business or properties of the Corporation, as
applicable, or any of its subsidiaries that are different from or in addition to
any such provisions referenced in the Transfer Notice shall not be considered to
be more favorable to the purchaser for purposes of this clause (3)).

If such a definitive written agreement is entered into with an unaffiliated
third party within such time period, the Transferring Entity shall be free for a
period of 270 days following the execution of such definitive written agreement
to consummate the Transfer of its Corporation Interest in accordance with the
terms thereof. If such Transfer is not consummated within such time period in
accordance with the terms of such definitive written agreement, the requirements
of this Section 4.1 shall apply anew to any further efforts by the Transferring
Entity to Transfer its Corporation Interest.

            Section 4.2 Change of Control. (a) If (i) a Change of Control occurs
with respect to a Duke Shareholder, PGCSI Parent shall have the option to
purchase such Duke Shareholder's Corporation Interest for Fair Market Value
pursuant to the provisions of Section 4.2(b), (c) and (d), or (ii) a Change of
Control occurs with respect to a Phillips Shareholder, DENG shall have the
option to purchase such Phillips Shareholder's Corporation Interest for Fair
Market Value pursuant to the provisions of Section 4.2(b), (c) and (d).

            (b) In the event of a transaction giving rise to a Change of Control
with respect to a Duke Shareholder or a Phillips Shareholder, as applicable, the
Party who has experienced such a Change of Control transaction (the "Changing
Party") shall promptly (and in any event within three days of the consummation
of such transaction) deliver notice (the "Control Notice") to the other Party or
Parties that are not Affiliates of the Changing Party (whether one or more, the
"Non-Changing Party") of such Change of Control transaction. The Non-Changing
Party shall have the right, to be exercised by notice (the "Control Acceptance")
on or before the 60th day following receipt of the Control Notice (the "Control
Offer Period"), to elect to purchase the Corporation Interest of the Changing
Party for Fair Market Value as of the date of the Change of Control. The Control
Acceptance shall set forth the name of a nationally recognized appraisal firm
(which may



                                      -8-
<PAGE>


be an investment banking, accounting or other firm that performs appraisal and
valuation services) designated by the Non-Changing Party as its appraisal firm
(the "Non-Changing Party Appraiser").

            (c) If the Non-Changing Party timely delivers the Control Acceptance
during the Control Offer Period, within 15 days from the date of receipt of the
Control Acceptance, the Changing Party shall notify the Non-Changing Party in
writing of the name of an appraisal firm (which may be an investment banking,
accounting or other firm that performs appraisal and valuation services)
designated as the Changing Party's appraisal firm (the "Changing Party
Appraiser"); PROVIDED, HOWEVER, that if the Changing Party fails to select an
appraisal firm, and the Changing Party is a Duke Shareholder, the Changing Party
Appraiser shall be Deloitte & Touche L.L.P., or, if the Changing Party is a
Phillips Shareholder, the Changing Party Appraiser shall be Ernst & Young
L.L.P.; PROVIDED, FURTHER, that if Deloitte & Touche L.L.P. or Ernst & Young
L.L.P., as the case may be, fails to accept the appointment within 30 days from
the date of receipt by the Changing Party of the Control Acceptance, the Control
Appraiser Committee shall consist solely of the Non-Changing Party Appraiser.
Except as provided in the second proviso of the immediately preceding sentence,
the Non-Changing Party Appraiser and the Changing Party Appraiser shall jointly
choose a third appraisal firm (which may be an investment banking, accounting or
other firm that performs appraisal and valuation services) within 15 days after
the appointment of the Non-Changing Party Appraiser (PROVIDED, HOWEVER, that if
they fail to select a third appraisal firm within 15 days after the appointment
of the Non-Changing Party Appraiser, such third firm (which shall be an
investment banking, accounting or other firm that performs appraisal and
valuation services) will be selected by the American Arbitration Association at
the request of either Party within 10 days after such request) (the "Neutral
Control Appraiser," and together with the Changing Party Appraiser and the
Non-Changing Party Appraiser, the "Control Appraiser Committee"). Once the
Control Appraiser Committee has been chosen, each of the Changing Party and
Non-Changing Party shall submit proposed Fair Market Values of the Changing
Party's Corporation Interest to the Control Appraiser Committee, together with
any supporting documentation such Party deems appropriate, as soon as
practicable, but in no event earlier than 30 days after the date of receipt of
the Control Acceptance nor later than (i) 30 days after the date of selection of
the Neutral Appraiser or (ii) in the event of the failure of Deloitte & Touche
L.L.P. or Ernst & Young L.L.P., as the case may be, to accept the appointment
within the required time period, 60 days from the date of receipt by the
Non-Changing Party of the Control Notice. If either Party fails to submit its
proposed Fair Market Value within the required time period, the Fair Market
Value proposed by the other Party (assuming such other Party has submitted its
proposed value within the required time period) shall be deemed to be the Fair
Market Value of the Changing Party's Corporation Interest for purposes of this
Section 4.2. If both Parties submit their respective proposed values on a timely
basis, the Control Appraiser Committee shall determine, by majority vote, the
Fair Market Value as of the date of the Change of Control of the Changing
Party's Corporation Interest, as promptly as possible (and in any event on or
before the 30th day after submittal of the competing proposals), which
determination shall be final and binding on the Parties. The cost of such
appraisal shall be paid in equal portions by (A) the Changing Party and (B) the
Non-Changing Party. Each of the Changing Party and the Non-Changing Party shall
provide to the other and, if applicable, the Control Appraisal Committee, all
information reasonably requested by them.

            (d) The closing of the Non-Changing Party's acquisition of the
Changing Party's Corporation Interest shall be consummated on or before the 60th
day after the determination of the



                                      -9-
<PAGE>


Fair Market Value in accordance with Section 4.2(c). The acquisition shall be
consummated at a closing held at the principal offices of the Corporation
(unless otherwise mutually agreed by the Changing Party and the Non-Changing
Party) at which time the purchase price, payable in the form of immediately
available funds, shall be delivered to the Changing Party, and the Changing
Party shall deliver or cause to be delivered to the Non-Changing Party (or, at
the option of the Non-Changing Party, to (i) an Affiliate of the Non-Changing
Party or (ii) if the interest being transferred represents the entire Duke
Corporation Interest or the entire Phillips Corporation Interest, a designee of
the Non-Changing Party, in each case as designated by the Non-Changing Party not
less than five days prior to the closing) such transfer documentation reasonably
acceptable to the Non-Changing Party (or such Affiliate or designee) as shall be
required to evidence the transfer of the Changing Party's Corporation Interest,
as the case may be, free and clear of all liens and encumbrances, except those
created under this Agreement.

            Section 4.3 Open Market Purchases and Transfers. Following the IPO,
subject to applicable federal and state securities laws, each Shareholder and
its Affiliates may make open-market purchases or sales of shares of Corporation
Common Stock.

            Section 4.4 Affiliate Transfers. If either a Duke Shareholder or a
Phillips Shareholder desires to Transfer all or any portion of its Corporation
Interest to an Affiliate, such Transfer shall only be permitted hereunder if the
transferee (other than any transferee that is already a party to this Agreement)
becomes a party to this Agreement by executing an adoption agreement in
substantially the form of Exhibit A hereto.

            Section 4.5 Void Transfers. Any purported Transfer of all or any
portion of a Corporation Interest not permitted by this Article IV shall be

agree, to the extent permitted by law, that final and unappealable judgment
against any of them in any action or proceeding contemplated above shall be

holders of a Majority of the then outstanding Phillips Registrable Securities
may request a registration by the Corporation under the Securities Act of all or
part of its or their Phillips Registrable Securities (a "Phillips Demand
Registration"); provided, that the number of Phillips Registrable Securities

Corporation will provide written notice of such registration request to all
holders of Registrable Securities and will, subject to the provisions of
Section 3(b) and Section 3(d), include in such registration all Registrable
Securities with respect to which the Corporation has received written requests

holder of the Corporation's notice. All requests made pursuant to this Section
3(a) will specify the number of Registrable Securities to be registered and will
also specify the intended method of disposition thereof; provided, however, that
such method of disposition will be limited to an underwritten offering if so
requested by the holders of the Phillips Registrable Securities who initiated
the request.




                                      -3-
<PAGE>


     (b) NUMBER OF REGISTRATIONS. The holders of Phillips Registrable Securities
will be entitled to request an aggregate of two Phillips Demand Registrations.
For purposes of this Section 3(b), a registration initiated as a Phillips Demand
Registration will not constitute a Phillips Demand Registration (i) unless such
registration is declared effective by the SEC and remains effective for the
period set forth in Section 7(a)(iii); provided, however, that a registration
which does not become effective after the Corporation has filed a registration
statement in accordance with the provisions hereof by reason of the refusal to
proceed of the initiating holders or such of the initiating holders as would
result in the inclusion of less than 3% of the then outstanding Common Stock
(other than any refusal to proceed (x) based upon the advice of their counsel
that the registration statement, or the prospectus contained therein, contains
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing, or that such
registration statement or such prospectus, or the distribution contemplated
thereby, otherwise violates or would, if such distribution using such prospectus
took place, violate any applicable state or federal securities law or (y)
following a material breach by the Corporation of its obligations hereunder, but
only if such breach has materially and adversely affected the initiating
holder's ability to consummate the proposed offering or the pricing of such
offering) shall be deemed to have been effected; (ii) if after such registration
has been declared effective by the SEC it is subject to any stop order,
injunction or other adverse order or action of the SEC or other governmental
authority which is not removed within 15 days; or (iii) if such registration is
withdrawn as a result of the withdrawal of the demand pursuant to Section 3(g)
hereof prior to the filing by the Corporation of a registration statement with
the SEC.

     (c) LIMITATION ON RIGHTS OF CORPORATION OR OTHER SECURITYHOLDERS TO
PIGGYBACK ON PHILLIPS DEMAND REGISTRATIONS. Neither the Corporation nor any of
its securityholders (other than the holders of Phillips Registrable Securities
in such capacity) has any right to include any of the Corporation's securities
in a registration statement initiated as a Phillips Demand Registration under
this Section 3 if such Demand Registration is an underwritten offering unless
(i) such securities are of the same class as the Phillips Registrable Securities
being registered, (ii) the managing underwriters agree that some or all of such
securities can be included without adversely affecting such offering or offering
price, and (iii) the Corporation, or the selling securityholders, as applicable,
agree to sell their securities on the same terms and conditions as apply to the
Phillips Registrable Securities and the holders of such Phillips Registrable
Securities. If any securityholders of the Corporation (other than the holders of
Phillips Registrable Securities in such capacity) register securities of the
Corporation in a Phillips Demand Registration (in accordance with the provisions
of this Section 3(c)), such securityholders will pay the fees and expenses of
counsel to such securityholders and their pro rata share of the Registration
Expenses if such pro rata share of the Registration Expenses for such
registration are not paid by the Corporation for any reason. The Corporation and
any such securityholders may withdraw their securities from a Phillips Demand
Registration; provided, however, if the Phillips Demand Registration is an
underwritten offering, they may do so only on the reasonable and customary terms
agreed upon by the managing underwriters for such offering.

     (d) PRIORITY ON PHILLIPS DEMAND REGISTRATIONS. If a Phillips Demand
Registration is an underwritten offering and the managing underwriters advise
the Corporation and the selling holders of the Phillips Registrable Securities
in writing that in their opinion the number of



                                      -4-
<PAGE>


Phillips Registrable Securities requested to be included exceeds the number of
securities which can be sold in such offering without adversely affecting the
proposed offering or the offering price, the Corporation will include in such
registration the number of Phillips Registrable Securities which in the opinion
of such underwriters can be sold without adversely affecting the proposed
offering or the offering price, and such securities will be allocated pro rata
among the holders of Phillips Registrable Securities requesting to be included
in the registration on the basis of the number of the Phillips Registrable
Securities requested to be included in such registration by their respective
holders. If securities (other than Phillips Registrable Securities) are proposed
to be included by the Corporation or its other securityholders in a Phillips
Demand Registration which is an underwritten offering (subject to and in
accordance with the provisions of Section 3(c)) and the managing underwriters
advise the Corporation and the selling holders of Phillips Registrable
Securities in writing that some but not all of said other securities can be sold
without adversely affecting the proposed offering or the offering price in such
underwritten offering, in addition to all of the Phillips Registrable Securities
being registered, those securities which are permitted to be included will be
allocated (i) first, to the Corporation, (ii) second, to the holders of Duke
Registrable Securities, allocated pro rata among the holders of Duke Registrable
Securities requesting to be included in the registration on the basis of the
number of Duke Registrable Securities requested to be included in such
registration by their respective holders and (iii) third, to the other
securityholders, allocated among them in such proportions as such
securityholders and the Corporation may agree.

     (e) SELECTION OF UNDERWRITERS. If any Phillips Demand Registration is an
underwritten offering, or a best efforts underwritten offering, the investment
banker or investment bankers and manager or managers that will administer the
offering will be selected by the holders of two-thirds (by number of shares) of
the Phillips Registrable Securities requested to be included in such offering;
provided, however, such investment bankers and managers must be reasonably
satisfactory to the Corporation.

     (f) OTHER REGISTRATION RIGHTS AGREEMENTS. Without the prior written consent
of the holders of a Majority of the Phillips Registrable Securities, the
Corporation will not enter into any agreement with any holder or prospective
holder of any securities of the Corporation which grants to such holder or
prospective holder any registration rights unless such agreement and the rights
granted thereunder are subject and subordinate to the rights of holders
hereunder.

     (g) WITHDRAWAL BY HOLDERS OF PHILLIPS REGISTRABLE SECURITIES. The holders
of Phillips Registrable Securities may withdraw a Phillips Demand Request at any
time and under any circumstances.

4.    DEMAND REGISTRATION WITH RESPECT TO DUKE REGISTRABLE SECURITIES.

     (a) REQUESTS FOR REGISTRATION. Subject to the provisions of Section 4(b),
at any time after 180 days following the closing of the IPO any holder or
holders of a Majority of the then outstanding Duke Registrable Securities may
request a registration by the Corporation under the Securities Act of all or
part of its or their Duke Registrable Securities (a "Duke Demand Registration");
provided that the number of Duke Registrable Securities requested to be
registered represents at least 3% of the Corporation's then outstanding Common
Stock. Within 15 days after receipt of such request, the Corporation will
provide written notice of such



                                      -5-
<PAGE>

registration request to all holders of Registrable Securities and will, subject
to the provisions of Section 4(b) and Section 4(d), include in such registration
all Duke Registrable Securities with respect to which the Corporation has
received written requests for inclusion therein within 15 days after
distribution to the applicable holder of the Corporation's notice. All requests
made pursuant to this Section 4(a) will specify the amount of Registrable
Securities to be registered and will also specify the intended method of
disposition thereof; provided, however, that such method of disposition will be
limited to an underwritten offering if so requested by the holders of the Duke
Registrable Securities who initiated the request.

     (b) NUMBER OF REGISTRATIONS. The holders of Duke Registrable Securities
will be entitled to request an aggregate of two Duke Demand Registrations. For
purposes of this Section 4(b), a registration initiated as a Duke Demand
Registration will not constitute a Duke Demand Registration (i) unless such
registration is declared effective by the SEC and remains effective for the
period set forth in Section 7(a)(iii); provided, however, that a registration
which does not become effective after the Corporation has filed a registration
statement in accordance with the provisions hereof by reason of the refusal to
proceed of the initiating holders or such of the initiating holders as would
result in the inclusion of less than 3% of the then outstanding Common Stock
(other than any refusal to proceed (x) based upon the advice of their counsel
that the registration statement, or the prospectus contained therein, contains
an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in light of the circumstances then existing, or that such
registration statement or such prospectus, or the distribution contemplated
thereby, otherwise violates or would, if such distribution using such prospectus
took place, violate any applicable state or federal securities law or (y)
following a material breach by the Corporation of its obligations hereunder, but
only if such breach has materially and adversely affected the initiating
holder's ability to consummate the proposed offering) shall be deemed to have
been effected; (ii) if after such registration has been declared effective by
the SEC it is subject to any stop order, injunction or other adverse order or
action of the SEC or other governmental authority which is not removed within 15
days; or (iii) if such registration is withdrawn as a result of the withdrawal
of the demand pursuant to Section 4(g) hereof prior to the filing by the
Corporation of a registration statement with the SEC.

     (c) LIMITATION ON RIGHTS OF CORPORATION OR OTHER SECURITYHOLDERS TO
PIGGYBACK ON DUKE DEMAND REGISTRATIONS. Neither the Corporation nor any of its
securityholders (other than the holders of Duke Registrable Securities in such
capacity) has any right to include any of the Corporation's securities in a
registration statement initiated as a Demand Registration under this Section 4
if such Demand Registration is an underwritten offering unless (i) such
securities are of the same class as the Duke Registrable Securities being
registered, (ii) the managing underwriters agree that some or all of such
securities can be included without adversely affecting such offering or offering
price, and (iii) the Corporation, or the selling securityholders, as applicable,
agree to sell their securities on the same terms and conditions as apply to the
Duke Registrable Securities and the holders of such Duke Registrable Securities.
If any securityholders of the Corporation (other than the holders of Duke
Registrable Securities in such capacity) register securities of the Corporation
in a Duke Demand Registration (in accordance with the provisions of this Section
4(c)), such securityholders will pay the fees and expenses of counsel to such
securityholders and their pro rata share of the Registration Expenses if such
pro rata share of the Registration Expenses for such registration are not paid
by the Corporation for





                                      -6-
<PAGE>


any reason. The Corporation and any such securityholders may withdraw their
securities from a Duke Demand Registration; PROVIDED, HOWEVER, if the Duke
Demand Registration is an underwritten offering, they may do so only on the
reasonable and customary terms agreed upon by the managing underwriters for such
offering.

     (d) PRIORITY ON DUKE DEMAND REGISTRATIONS. If a Duke Demand Registration is
an underwritten offering and the managing underwriters advise the Corporation
and the selling holders of the Duke Registrable Securities in writing that in
their opinion the number of Duke Registrable Securities requested to be included
exceeds the number of securities which can be sold in such offering without
adversely affecting the proposed offering or the offering price, the Corporation
will include in such registration the number of Duke Registrable Securities
which in the opinion of such underwriters can be sold without adversely
affecting the proposed offering or the offering price, and such securities will
be allocated pro rata among the holders of Duke Registrable Securities
requesting to be included in the registration on the basis of the number of the
Duke Registrable Securities requested to be included in such registration by
their respective holders. If securities (other than Duke Registrable Securities)
are proposed to be included by the Corporation or its other securityholders in a
Duke Demand Registration which is an underwritten offering (subject to and in
accordance with the provisions of Section 4(c)) and the managing underwriters
advise the Corporation and the selling holders of Duke Registrable Securities in
writing that some but not all of said other securities can be sold without
adversely affecting the proposed offering or the offering price in such
underwritten offering, in addition to all of the Duke Registrable Securities
being registered, those securities which are permitted to be included will be
allocated (i) first, to the Corporation, (ii) second, to the holders of Phillips
Registrable Securities, allocated pro rata among the holders of Phillips
Registrable Securities requesting to be included in the registration on the
basis of the number of Phillips Registrable Securities requested to be included
in such registration by their respective holders and (iii) third, to the other
securityholders, allocated among them in such proportions as such
securityholders and the Corporation may agree.

     (e) SELECTION OF UNDERWRITERS. If any Duke Demand Registration is an
underwritten offering, or a best efforts underwritten offering, the investment
banker or investment bankers and manager or managers that will administer the
offering will be selected by the holders of two-thirds (by number of shares) of
the Duke Registrable Securities requested to be included in such offering;
PROVIDED, HOWEVER, such investment bankers and managers must be reasonably
satisfactory to the Corporation.

     (f) OTHER REGISTRATION RIGHTS AGREEMENTS. Without the prior written consent
of the holders of a Majority of the Duke Registrable Securities, the Corporation
will not enter into any agreement with any holder or prospective holder of any
securities of the Corporation which grants to such holder or prospective holder
any registration rights unless such agreement and the rights granted thereunder
are subject and subordinate to the rights of holders hereunder.

     (g) WITHDRAWAL BY HOLDERS OF DUKE REGISTRABLE SECURITIES. The holders of
Duke Registrable Securities may withdraw a Duke Demand Request at any time and
under any circumstances.

5.    PIGGYBACK REGISTRATIONS.

     (a) RIGHT TO PIGGYBACK. If at any time after consummation of the IPO the
Corporation proposes to register any securities under the Securities Act in
connection with the public offering of such securities (other than a
registration relating to employee benefit plans or a corporate reorganization or
acquisition, or a registration on any form that does not permit inclusion of
sales of Registrable Securities) (a "Piggyback Registration"), the Corporation
will give written notice to all holders of Registrable Securities of its
intention to effect such a registration not later than the earlier to occur of
(i) 10 days following receipt by the Corporation of notice of exercise of demand
registration rights or (ii) 30 days prior to the anticipated filing date;
PROVIDED, that such notice indicate the number of shares proposed to be
registered, the proposed means of distribution of such securities and the
proposed managing underwriters of such offering; PROVIDED, HOWEVER, that the
Corporation shall not be required to give such notice or to include any
Registrable Securities in a Piggyback Registration unless the Registrable
Securities to be so included are of the same class as the other securities to be
included in such registration. Subject to the provisions of Sections 5(b) and
(c), the Corporation will include in such Piggyback Registration all Registrable
Securities with respect to which the Corporation has received written requests
for inclusion therein within 15 days after delivery of the Corporation's notice.
The holders of Registrable Securities will be permitted to withdraw all or any
part of such holder's Registrable Securities from a Piggyback Registration at
any time prior to the date such Piggyback Registration becomes effective with
the SEC; PROVIDED, HOWEVER, if the Piggyback Registration is an underwritten
offering, the holders of Registrable Securities may do so only on the reasonable
and customary terms agreed upon by the managing underwriters for such offering.
If a Piggyback Registration is an underwritten offering effected under (i)
Section 5(b), all Persons whose securities are included in the Piggyback
Registration will be obligated to sell their securities on the same terms and
conditions as apply to the securities being issued and sold by the Corporation
or (ii) Section 5(c), all Persons whose securities are included in the Piggyback
Registration will be obligated to sell their securities on the same terms and
conditions as apply to the securities being sold by the Person or Persons who
initiated the Piggyback Registration under Section 5(c). The foregoing
notwithstanding, if, at any time after giving written notice of a Piggyback
Registration but prior to the effective date of the registration statement filed
in connection therewith, the Corporation shall determine for any reason not to
register the securities described in its notice of its intention to file a
registration statement, the Corporation may, at its election, give written
notice of such determination to the holders of Registrable Securities and
thereupon shall be relieved of its obligation to register any Registrable
Securities in such registration.

     (b) PRIORITY ON PRIMARY REGISTRATIONS. If a Piggyback Registration is an
underwritten primary registration on behalf of the Corporation, and the managing
underwriters advise the Corporation in writing that in their opinion the total
number of securities requested to be included in such registration exceeds the
number of securities which can be sold in such offering without adversely
affecting the offering or the offering price, the Corporation will include in
such registration: first, all securities the Corporation proposes to sell, then,
to the extent that additional securities can, in the opinion of such
underwriters, be included in such registration without adversely affecting the
offering or the offering price, (i) first, up to the full number of securities
requested to be included in such registration by holders of Registrable
Securities allocated pro rata among such holders on the basis of the number of
securities requested to be



                                      -8-
<PAGE>


included therein by each such holder, (ii) second, up to the full number of
securities requested to be included in such registration by other holders of
securities entitled to include securities in such Piggyback Registration, and
(iii) third, such additional securities as may be agreed upon by the Corporation
and any other securityholders.

     (c) PRIORITY ON SECONDARY REGISTRATIONS. If a Piggyback Registration is an
underwritten secondary registration on behalf of holders of the Corporation's
securities pursuant to the exercise of such holders' demand registration rights
or otherwise, and the managing underwriters advise the Corporation in writing
that in their opinion the number of securities requested to be included in such
registration exceeds the number of securities which can be sold in such offering
without adversely affecting the offering or the offering price, the Corporation
will include in such registration (i) first, the number of securities proposed
to be included therein on behalf of the holders of the Corporation's securities
exercising demand registration rights, allocated among the holders of such
securities in such proportions as the Corporation and such holders may agree,
(ii) second, up to the full number of securities the Corporation proposes to
sell, (iii) third, to the extent that additional securities can, in the opinion
of such underwriters, be included in such registration without adversely
affecting the offering or the offering price, up to the full number of
securities requested to be included in such registration by the holders of
Registrable Securities and other holders of securities entitled to include
securities in such Piggyback Registration, allocated pro rata among such holders
on the basis of the number of securities requested to be included therein by
each such holder and (iv) fourth, any additional securities that may be included
in such registration, in the opinion of such underwriters, without adversely
affecting the offering or the offering price, as may be agreed upon by the
Corporation and any other securityholders.

     (d) SELECTION OF UNDERWRITERS. If any Piggyback Registration is an
underwritten offering, as between the Corporation and the holders of the
Registrable Securities, the Corporation will have the sole right to select the
investment banker or investment bankers and manager or managers to administer
the offering.

     (e) LIMITATION. No Piggyback Registration effected under this Section 5 (i)
shall be deemed to constitute a Demand Registration or to have been effected
pursuant to Section 3 or Section 4 hereof or (ii) shall release the Corporation
of its obligations to effect any Demand Registration upon request as provided
under Section 3 or Section 4 hereof.

6.    DEFERRAL OF FILING; PREEMPTION.

     (a) DEFERRAL OF FILING. Anything herein to the contrary notwithstanding,
the Corporation may defer the filing of any registration statement otherwise
required to be filed by it pursuant to Section 3 or 4 for up to 180 days if the
Corporation notifies each requesting holder promptly after such request that the
Corporation's Board of Directors has determined in its good faith judgement that
the requested registration and offering would require disclosure of pending or
contemplated matters or information, the disclosure of which would likely be
detrimental to the Corporation or materially interfere with its business or a
pending or contemplated material transaction involving the Corporation. In
addition to the foregoing deferral rights, the Corporation shall not be required
to file any registration statement pursuant to Section 3 or 4 (i) within 120
days after the effectiveness of a registration statement relating to a Demand



                                      -9-
<PAGE>


Registration or (ii) within 180 days (or such shorter period as may be agreed to
by the underwriters but in no event less than 120 days) after the effectiveness
of a registration statement referred to in Section 5.

     (b) PREEMPTION BY THE CORPORATION. Anything herein to the contrary
notwithstanding, in the event the Corporation reasonably expects to file, within
60 days of a demand for registration, a registration statement pertaining to
securities for the account of the Corporation (except a registration statement
on Form S-4 or Form S-8 or with respect to a transaction subject to Rule 145
under the Securities Act) then such request shall constitute a request made
pursuant to Section 5 hereof to include in such registration statement all
Registrable Securities subject to such request and the Corporation shall not be
obligated to file a separate registration statement for the Registrable
Securities subject to such request; PROVIDED, that the Corporation is actively
employing in good faith all reasonable efforts to cause such registration
statement to become effective.

     (c) TERMINATION OF DEFERRAL PERIOD. In the case of a deferral pursuant to
Section 6(a), the deferral period shall terminate upon the earlier of the
completion or abandonment of the relevant securities offering or sale,
Corporation business or other pending or contemplated material transaction.
After the termination or expiration of any deferral period and without further
request from the holders of Registrable Securities, the relevant Demand
Registration shall be reinstated, and the Corporation shall effect the filing of
the relevant Demand Registration unless the initiating holders shall have, prior
to the filing of such registration, withdrawn the initial request.

7.    REGISTRATION PROCEDURES.

     (a) Subject to the terms hereof, whenever the holders of Registrable
Securities have requested that any Registrable Securities be registered in
accordance with the terms and conditions of this Agreement, the Corporation will
use its reasonable best efforts to effect the registration and to permit the
sale of such Registrable Securities in accordance with the intended method of
disposition thereof, and pursuant thereto the Corporation will promptly:

          (i) prepare and file with the SEC, subject to the availability of all
     required consents of independent accountants (which the Corporation agrees
     to use all reasonable efforts to obtain), not later than 60 days after
     receipt of a request to file a registration statement with respect to such
     Registrable Securities, a registration statement with respect to such
     Registrable Securities, and use its reasonable best efforts to cause such
     registration statement to become effective; PROVIDED, that each such
     registration statement will be on a form for which the Corporation then
     qualifies, which is available for the sale of the Registrable Securities in
     accordance with the intended method of disposition thereof, and will
     provide for the registration of at least such number of shares as shall
     have been demanded be registered; PROVIDED, HOWEVER, that before filing a
     registration statement or prospectus or any amendments or supplements
     thereto, the Corporation will furnish to each of the holders including
     shares therein, and the managing underwriters, if any, draft copies of all
     such documents proposed to be filed a reasonable period prior to such
     filing, which documents will be subject to the reasonable review of each of
     such holders, and the managing underwriters, if any, and their respective
     agents and



                                      -10-
<PAGE>


     representatives and (x) the Corporation will not include in any
     registration statement information concerning or relating to the holders
     including shares therein to which any such holder shall reasonably object
     in writing (unless the inclusion of such information is required by
     applicable law or the regulations of any securities exchange to which the
     Corporation may be subject or is required to prevent a material omission or
     misstatement in the filing), and (y) with respect to any Duke Demand
     Registration or Phillips Demand Registration, respectively, the Corporation
     will not file any Demand Registration or amendment thereto or any
     prospectus or any supplement thereto to which Duke or Phillips,
     respectively, shall reasonably object in writing;

          (ii) notify each seller of Registrable Securities of any stop order
     issued by the SEC and take all reasonable actions required to prevent the
     entry of such stop order or to remove it at the earliest possible time if
     entered;

          (iii) prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection therewith
     as may be necessary to keep such registration statement effective for a
     period of not less than 90 days, or such shorter period as may be required
     if all Registrable Securities covered by such registration statement are
     sold prior to the expiration of such 90-day period (except in connection
     with an underwritten offering, in which case such registration statement
     shall be kept effective as long as the underwriters reasonably request in
     the underwriting agreement), and comply with the provisions of the
     Securities Act with respect to the disposition of all securities covered by
     such registration statement during such period in accordance with the
     intended methods of disposition by the sellers thereof set forth in such
     registration statement;

          (iv) furnish without charge to each seller and managing underwriters
     of Registrable Securities such number of copies of such registration
     statement, each amendment and supplement thereto (in each case including
     all exhibits thereto), the prospectus included in such registration
     statement (including each preliminary, final, summary, amended or
     supplemented prospectus) and such other documents as such seller and
     managing underwriters may reasonably request in order to facilitate the
     disposition of the Registrable Securities owned by such seller;

          (v) use its reasonable best efforts to register or qualify such
     Registrable Securities under such other securities or blue sky laws of such
     jurisdictions within the United States as any seller reasonably requests,
     keep such registrations or qualifications in effect for so long as the
     registration statement remains in effect, and do any and all other acts and
     things which may be reasonably necessary or advisable to enable such seller
     to consummate the disposition in such jurisdictions of the Registrable
     Securities owned by such seller; PROVIDED, HOWEVER, that the Corporation
     will not be required to (i) qualify generally to do business in any
     jurisdiction where it would not otherwise be required to qualify but for
     this Section 7(a)(v), (ii) subject itself to taxation in any such
     jurisdiction or (iii) consent to general service of process in any such
     jurisdiction;

          (vi) use its reasonable best efforts to cause the Registrable
     Securities covered by such registration statement to be registered with or
     approved by such other



                                      -11-
<PAGE>


     governmental agencies or authorities within the United States as may be
     necessary to enable the seller or sellers thereof to consummate the
     disposition of such Registrable Securities;

          (vii) notify each seller of such Registrable Securities, at any time
     when a prospectus relating thereto is required to be delivered under the
     Securities Act, of the happening of any event of which the Corporation is
     aware as a result of which the prospectus included in such registration
     statement or any document incorporated therein by reference contains an
     untrue statement of a material fact or omits to state any material fact
     necessary to make the statements therein not misleading in light of the
     circumstance then existing, and prepare and file promptly with the SEC a
     supplement or amendment to such prospectus or any such document
     incorporated therein by reference so that, as thereafter delivered to the
     purchasers of such Registrable Securities, such prospectus will not contain
     an untrue statement of a material fact or omit to state any material fact
     necessary to make the statements therein not misleading in light of the
     circumstance then existing;

          (viii) use its reasonable best efforts to cause all such Registrable
     Securities to be listed on each securities exchange on which similar
     securities issued by the Corporation are then listed or traded;

          (ix) provide a transfer agent and registrar for all Registrable
     Securities and a CUSIP number for all such Registrable Securities, in each
     case not later than the effective date of such registration statement;

          (x) enter into such customary agreements (including an underwriting
     agreement in customary form with customary lock-up provisions not to exceed
     90 days from the date of the prospectus) and take such other actions in
     connection therewith as the holders of a Majority of the Registrable
     Securities being registered or the managing underwriters, if any,
     reasonably request in order to expedite or facilitate the disposition of
     such Registrable Securities; and make such representations and warranties
     with respect to the registration statement, post-effective amendment or
     supplement thereto, prospectus or any amendment or supplement thereto, and
     documents incorporated by reference, if any, to the managing underwriters
     of the Registrable Securities, in form, substance and scope as are
     customarily made by the Corporation in connection with offerings of
     Registrable Securities in transactions of such kind;

          (xi) make available for inspection by any underwriter participating in
     any disposition pursuant to such registration statement,  and any attorney,
     accountant or other agent retained by any such  underwriter,  all financial
     and other  records,  pertinent  corporate  documents and  properties of the
     Corporation,  and cause the Corporation's officers, directors and employees
     and accountants to supply all information  reasonably requested by any such
     underwriter,   attorney,  accountant  or  agent  in  connection  with  such
     registration  statement,  in  each  case  upon  receipt  of an  appropriate
     confidentiality agreement;



                                      -12-

          (xii) in the case of an underwritten offering, obtain a cold comfort
     letter from the Corporation's independent public accountants in customary
     form and covering such matters of the type customarily covered by cold

          (xiii)otherwise use its reasonable best efforts to comply with all
     applicable rules and regulations of the SEC, and generally make available
     to its security holders, as soon as reasonably practicable, an earnings
     statement covering the period of at least twelve months, but not more than
     eighteen months, beginning with the first month after the effective date of
     the Registration Statement, which earnings statement will satisfy the
     provisions of Section 11(a) of the Securities Act and may be prepared in
     accordance with Rule 158 under the Securities Act.

     (b) The Corporation may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Corporation in
writing such information regarding the seller and the distribution of such
securities as the Corporation may from time to time reasonably request and to
timely complete and execute all questionnaires, powers of attorney, indemnities,
hold-back agreements, underwriting agreements and other documents reasonably
requested by the Corporation.

9.    INDEMNIFICATION; CONTRIBUTION.

     (a) INDEMNIFICATION BY CORPORATION. In the event any Registrable Securities
are included in a registration statement pursuant to this Agreement, the
Corporation shall indemnify and hold harmless each holder of such Registrable
Securities, its employees, officers, directors and constituent partners and each
Person who controls such holder (within the meaning of the Securities Act and
the Exchange Act) against all losses, claims, damages, liabilities and expenses
(or actions in respect thereof) arising out of or based upon any untrue or
alleged untrue statement of a material fact contained in any registration
statement or preliminary or final prospectus relating to the registration of
such Registrable Securities or any amendment or supplement thereto or any
document incorporated by reference therein or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances in which they were
made, not misleading, except insofar as the same are contained in any
information furnished in writing to the Corporation by or on behalf of such
holder or other indemnified Person expressly for use therein or caused by such
holder's failure to deliver a copy of the registration statement or prospectus
or any amendments or supplements thereto after the Corporation has furnished
such holder with a sufficient number of copies of the same. Subject to the
provisions of Section 9(c), the Corporation will reimburse each holder of
Registrable Securities, its officers, directors, constituent partners and
controlling Persons for any reasonable legal and other expenses as incurred in
connection with investigating or defending any such losses, claims, damages,
liabilities, expenses or actions for which such Person is entitled to
indemnification hereunder. In connection with a firm commitment or best efforts

agents, their officers, directors, constituent partners and each Person who
controls such underwriters (within the meaning of the Securities Act and the
Exchange Act) or agents to the same extent as provided above (or such greater
extent as may be customarily required by the managing underwriters) with respect
to the indemnification of the holders of Registrable Securities.

     (b) INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES. In connection with
any registration statement in which a holder of Registrable Securities is
participating, such holder will furnish to the Corporation in writing such

by reference therein and shall indemnify and hold harmless the Corporation, its
employees, directors and officers, each Person who controls the Corporation
(within the meaning of the Securities Act and the Exchange Act) and all other
prospective sellers and their respective directors, officers and controlling
Persons (within the meaning of the Securities Act and the Exchange Act) against
any losses, claims, damages, liabilities and expenses (or actions in respect
thereof) arising out of or based upon any untrue or alleged untrue statement of
a material fact or any omission or alleged omission of a material fact required
to be stated in any registration statement or preliminary or final prospectus
relating to the registration of such Registrable Securities or any amendment
thereof or supplement thereto or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, to the
extent, but only to the extent, that such untrue or alleged untrue statement or
omission or alleged omission is contained in any written information or
affidavit furnished by or on behalf of such holder specifically for use in such
registration statement or prospectus and then only to the extent of the total
proceeds received by such holder of Registrable Securities. Subject to the
provisions of Section 9(c), the



                                      -14-
<PAGE>


holders of Registrable Securities participating in any registration will
reimburse, to the extent of the total proceeds received by the holders of
Registrable Securities, the Corporation, its officers, directors and controlling
Persons and all other prospective sellers and their respective directors,
officers and controlling Persons for any reasonable legal and other expenses as
incurred in connection with investigation or defending any such losses, claims,
damages, liabilities, expenses or actions.

     (c) CONDUCT OF INDEMNIFICATION PROCEEDINGS. Any Person entitled to
indemnification hereunder will (i) give prompt notice to the indemnifying party
of any claim with respect to which it seeks indemnification (but omission of
such notice shall not relieve the indemnifying party from liability hereunder
except to the extent such indemnifying party is actually prejudiced by such
failure to give notice) and (ii) unless in such indemnified party's reasonable
judgment a conflict of interest may exist between such indemnified and
indemnifying parties with respect to such claim, permit such indemnifying party
to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. The indemnifying party will not be subject to any liability
for any settlement made without its consent (but such consent will not be
unreasonably withheld or delayed). No indemnifying party will consent to entry
of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of an unconditional release from all liability in respect to
such claim or litigation and does not subject the indemnified party to any
material injunctive relief or other material equitable remedy. An indemnifying
party who is not entitled to, or elects not to, assume the defense of a claim
will not be obligated to pay the fees and expenses of more than one counsel for
all parties indemnified by such indemnifying party with respect to such claim.

     (d) CONTRIBUTION. If the indemnification provided for in Section 9(a) or
Section 9(b) is unavailable or insufficient to hold harmless each of the
indemnified parties against any losses, claims, damages, liabilities and
expenses (or actions in respect thereof) to which such persons may become
subject under the Securities Act, then the indemnifying party shall, in lieu of
indemnifying each party entitled to indemnification hereunder, contribute to the
amount paid or payable by such party as a result of such losses, claims,
damages, liabilities or expenses in such proportion as is appropriate to reflect
the relative fault of the indemnifying party on the one hand and such
indemnified persons on the other in connection with the statements or omissions
or alleged statements or omissions that resulted in such losses, claims,
damages, liabilities or expenses. The relative fault of such persons shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact, or omission or alleged omission to state a
material fact, relates to information supplied by or concerning the indemnifying
party on the one hand, or by such indemnified person on the other, and such
person's relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. The parties hereto agree that it
would not be just and equitable if contribution pursuant to this Section 9(d)
were determined by pro rata allocation or by any other allocation that does not
take into account the equitable considerations referred to in this Section 9(d).
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities or expenses referred to above shall be deemed to
include (subject to the limitations set forth in Section 9(b) or 9(c) hereof)
any legal or other fees or expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action, proceeding
or claim. No person guilty of fraudulent misrepresentation within the



                                      -15-
<PAGE>


meaning of the Act shall be entitled to contribution from any person that is not
guilty of such fraudulent misrepresentation.

     (e) PRIORITY OF INDEMNIFICATION. Notwithstanding the foregoing, to the
extent that provisions on indemnification and contribution contained in the
underwriting agreement entered into in connection with an underwritten offering
are in conflict with the foregoing, the provisions of the underwriting agreement
shall prevail.

     (f) PAYMENT. The indemnification and contribution required by this Section
9 shall be made by periodic payments of the amount thereof during the course of
the investigation or defense, as and when bills are received or expense, loss,
damage or liability is incurred.

     (g) BENEFICIARIES OF INDEMNIFICATION. The obligations of the Corporation
and the holders of Registrable Securities under this Section 9 shall be in
addition to any liability that they may otherwise have.

10.    RULE 144.

      The Corporation covenants that after the consummation of the IPO it will
use its reasonable best efforts to timely file the reports required to be filed
by it under the Securities Act and the Exchange Act and the rules and
regulations adopted by the SEC thereunder (or, if the Corporation is not
required to file such reports, it will, upon the request of any holder of
Registrable Securities, make publicly available such information), all to the
extent required from time to time to enable such holder to sell Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (a) Rule 144 under the Securities Act, as such
Rule may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the SEC. Upon the request of any holder of Registrable
Securities, the Corporation will deliver to such holder a written statement as
to whether it has complied with such requirements.

11.    PARTICIPATION IN UNDERWRITTEN REGISTRATIONS; MARKET STAND-OFF AGREEMENT.

     (a) PARTICIPATION IN UNDERWRITTEN REGISTRATION. No Person may participate
in any underwritten registration hereunder unless such Person (i) agrees to sell
such Person's securities on the basis provided in any underwriting arrangements
approved by the Persons entitled hereunder to approve such arrangements and (ii)
completes and executes all customary questionnaires, powers of attorney,
underwriting agreements, lock-ups and other documents required under the terms
of such underwriting arrangements.

     (b) MARKET STAND-OFF AGREEMENT. Each holder of Registrable Securities
agrees, whether or not it is participating in such registration statement, that
it shall not, to the extent requested by an underwriter of Common Stock (or
other securities of the Corporation), sell or otherwise transfer or dispose of
any securities of the Corporation (other than those included in the
registration) during the 90 day period following the effective date of a
registration statement of the Corporation filed under the Securities Act if such
holder owns or has the right to acquire 5% or more of the outstanding Common
Stock. In order to enforce the foregoing covenant, the Corporation may impose
stop-transfer instructions with respect to the securities of the Corporation
owned by holders of Registrable Securities until the end of such 90 day period.



                                      -16-

12.   MISCELLANEOUS.

     (a) RIGHT TO SUSPEND. The Corporation may, by notice in writing to each
holder of Registrable Securities, require the holder of Registrable Securities
to suspend use of any prospectus included in a registration statement filed
hereunder if the Corporation reasonably determines that it contains an untrue
statement of a material fact or omits to state any material fact necessary to
make the statements therein not misleading or that any transaction in which the
Corporation is engaged or proposes to engage, or any event that has occurred or
is expected to occur, would require an amendment to such registration statement
or a supplement to such prospectus (including any such amendment or supplement
made through incorporation by reference to a report filed under Section 13 of
the Exchange Act). Each holder of Registrable Securities agrees that, upon
receipt of any notice from the Corporation of the happening of any event of the
kind described in this Section 12(a), such holder will forthwith discontinue
disposition of Registrable Securities pursuant to the registration statement
covering such Registrable Securities until such holder's receipt of the copies
of a properly supplemented or amended prospectus, and, if so directed by the
Corporation, such holder will deliver to the Corporation all copies, other than
permanent file copies, then in such holder's possession, of the most recent
prospectus covering such Registrable Securities at the time of receipt of such
notice. In the event the Corporation gives any such notice, the time period
mentioned in Section 7(a)(iii), if applicable, will be extended by the number of
days during the period from and including the date of the giving of such notice
to and including the date when each seller of Registrable Securities covered by
such registration statement has received the copies of such supplemented or
amended prospectus. The Corporation agrees to use its reasonable best efforts to
cause any suspension of use of any prospectus pursuant to this paragraph to be
as short a period of time as possible.

     (b) REMEDIES. No holder of Registrable Securities shall have any right to
take any action to restrain, enjoin or otherwise delay any registration as a
result of any controversy that might arise with respect to the interpretation or
implementation of this Agreement.

     (c) AMENDMENTS AND WAIVERS. The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given unless the Corporation has obtained the
written consent of (i) the holders of at least a Majority of the outstanding
Phillips Registrable Securities and (ii) the holders of at least a Majority of
the outstanding Duke Registrable Securities. Each holder of any Registrable
Securities at the time or thereafter shall be bound by any consent authorized by
this Section 12(c), whether or not such holder consented or whether or not such
Registrable Securities have been marked to indicate such consent.

     (d) REGISTRABLE SECURITIES HELD BY THE CORPORATION OR ITS SUBSIDIARIES.
Whenever the consent or approval of holders of all or any specified percentage
of Registrable Securities is required hereunder, Registrable Securities held by
the Corporation or any of its subsidiaries will not be counted in determining
whether such consent or approval was given by such holders.

     (e) NOTICES. All notices or other communications provided for hereunder
shall be in writing and shall be effective (i) on the day on which delivered if
delivered personally or transmitted by telex or telegram or telecopier with
evidence of receipt, (ii) one business day after



                                      -17-
<PAGE>

the date on which the same is delivered to a nationally recognized overnight
courier service with evidence of receipt, or (iii) three days after the date on
which the same is deposited, postage prepaid, in the U.S. mail, sent by
certified or registered mail, return receipt requested, and addressed to the
party to be notified at the address indicated below for the Corporation, or at
the address for the holder of the Registrable Securities set forth in a registry
maintained by the Corporation, or at such other address and/or telecopy or telex
number and/or to the attention of such other person as the Corporation or the
holder of the Registrable Securities may designate by ten-day advance written
notice.

     (f) SUCCESSORS AND ASSIGNS; TRANSFER OF REGISTRATION RIGHTS. This Agreement
will inure to the benefit of and be binding upon the successors and permitted
assigns of each of the parties. The registration rights granted by this
Agreement may be transferred or assigned by operation of law or in connection
with any transfer or assignment of Registrable Securities (other than in a
transaction described in clause (i), (ii) or (iv) of Section 2) provided that
(x) upon such transfer or assignment the transferee or assignee holds
Registrable Securities equal to at least 10% of the then outstanding Common
Stock, (y) such transferee or assignee agrees in writing to be bound by the
terms of this Agreement and (z) the Corporation is given written notice of such
transfer or assignment within 10 days after such transfer or assignment, setting
forth the name and address of the transferee or assignee and identifying the
Registrable Securities with respect to which such registration rights have been
assigned. For purposes of exercise of requests pursuant to Section 3 or Section
4, transferees shall be included with Duke or Phillips, as the case may be,
based on who was the original transferor of such Registrable Securities.

     (g) COUNTERPARTS. This Agreement may be executed in one or more
counterparts and by the parties hereto in separate counterparts, all of which
will constitute one and the same agreement and shall become effective when one
or more counterparts have been signed by each of the parties hereto and
delivered (including by facsimile) to the other parties.

     (h) HEADINGS. The headings in this Agreement are for convenience of
reference only and will not limit or otherwise affect the meaning hereof.

     (i) GOVERNING LAW; JURISDICTION. This Agreement will be governed by and
construed in accordance with the laws of the State of Delaware, without giving
effect to conflict of law principles. Any holder of Registrable Securities may
bring any action or proceeding to enforce or arising out of this Agreement or in
the instruments and agreements annexed hereto in any court of competent
jurisdiction.

     (j) SEVERABILITY. In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, the validity, legality and enforceability of
any such provision in every other respect and of the remaining provisions
contained herein will not be affected or impaired thereby.

     (k) TERMINATION OF REGISTRATION RIGHTS. The rights of any holder hereunder
to request registration or inclusion in any registration pursuant to Section 4
or 5, respectively, with respect to any Duke Registrable Securities shall
terminate at such time as Duke and its Affiliates shall own less than 10% of the
outstanding common stock of the Corporation. The rights of any holder hereunder
to request registration or inclusion in any registration pursuant to Section 3



                                      -18-
<PAGE>

or 5, respectively, with respect to any Phillips Registrable Securities shall
terminate at such time as Phillips and its Affiliates shall own less than 10% of
the outstanding common stock of the Corporation.

     (l) ENTIRE AGREEMENT. This Agreement is intended by the parties as a final

PHILLIPS AND DUKE ENERGY CLOSE TRANSACTION, LAUNCH NEW GAS
GATHERING AND PROCESSING COMPANY

BUSINESS WIRE - APRIL 03, 2000 09:14

BARTLESVILLE, Okla.--(BUSINESS WIRE)--April 3, 2000--PHILLIPS PETROLEUM Company
(NYSE:P) and Duke Energy (NYSE:DUK) announced today they have closed the
transaction that combines Duke Energy's gas gathering and processing business
with Phillips' Gas Gathering, Processing and Marketing (GPM) unit. The combined
company, named Duke Energy Field Services (DEFS), further strengthens its
national leadership position in natural gas liquids production (about 400,000
barrels per day) and natural gas gathering and processing.

In connection with the combination, DEFS will borrow approximately $2.75 billion
of short-term debt. The proceeds of the debt will be used to make one-time cash
distributions of approximately $1.2 billion to both Phillips and Duke Energy and
to pay $325 million and $20 million to Duke Energy and to Phillips,
respectively, as reimbursement for the acquisition of additional assets since
the Combination Agreement was signed in December 1999. The transaction is
expected to be accretive immediately to both PHILLIPS and Duke Energy.

Jim W. Mogg, previously president and chief executive officer of Duke Energy's
gathering and processing business, assumed the position of chairman, president
and chief executive officer of the new company. Michael Panatier, president and
chief executive of GPM prior to the combination transaction, has been appointed
vice chairman of the new company.

"As the natural gas industry continues to grow and consolidate, customer service
and economies of scale will be critical factors in determining which companies
are the ultimate winners," said Mogg. "The fact that DEFS and GPM have
complementary strategic objectives and assets gives the combined company greater
flexibility to meet and exceed customer needs and to successfully pursue future
opportunities.

"The employees of the new DEFS have the demonstrated skill sets and expertise to
optimize and rationalize assets, as well as the strategic ability to acquire and
integrate new assets moving forward," Mogg added. "That makes all the difference
in an industry where innovation and an entrepreneurial spirit set the standard."

Jim Mulva, chairman and chief executive officer of Phillips Petroleum Company,
said, "This transaction is an integral step in Phillips' strategy to position
each of our business lines for growth and improve our return on capital
employed, while maintaining Phillips' diversification and strength through
integration. In addition, this transaction makes GPM part of a much larger, more
competitive asset base."

"This combination clearly demonstrates Duke Energy's ability to maximize value
from its existing business units and assets," said Richard B. Priory, chairman,
president and chief executive officer of Duke Energy. "We will continue to
pursue opportunities that propel Duke Energy toward its goal of becoming the
world's premier global energy merchant."

DEFS, headquartered in Denver, Colo., is the nation's largest producer of
natural gas liquids (NGLs), one of the largest natural gas gatherers and
marketers and one of the largest NGL marketers. The company operates in 11
states, including Wyoming, Colorado, Kansas, Oklahoma, New Mexico, Texas,
Louisiana, Alabama and Mississippi, and along the Gulf Coast and in northwestern
Alberta, Canada. DEFS now owns and operates 70 plants and 57,000 miles of
pipeline.

Duke Energy, a diversified multi-national energy company, creates value for
customers and shareholders through an integrated network of energy assets and
expertise. Duke Energy manages a dynamic portfolio of natural gas and electric
supply, delivery and trading businesses - generating revenues of nearly $22
billion in 1999. Duke Energy, headquartered in Charlotte, N.C., is a Fortune 100
company traded on the New York Stock Exchange under the symbol DUK. More
