Party's Net Working Capital Statement.

          (c) Unless, within 45 days after receipt by a Party of the other
Party's Net Working Capital Statement, the receiving Party notifies the
delivering Party that the receiving Party does not agree with the determination
of Net Working Capital as of the Closing Date set forth in such delivering
Party's Net Working Capital Statement, such delivering Party's Net Working
Capital determination shall be final and binding on the Parties and shall be
deemed such Party's "ACTUAL NET WORKING CAPITAL." If the receiving Party
notifies the delivering Party in writing during such period that the receiving
Party does not agree with the delivering Party's Net Working Capital
determination, then the Parties shall discuss such disagreement for 15 days from
the date of such written notice and, if such disagreement is not resolved at the
end of such 15-day period, the disagreement will be submitted to Arthur Andersen
L.L.P. (the "NEUTRAL FIRM"). The Neutral Firm will review the disagreement and,
as soon as possible but in any event not later than 60 days after the
disagreement was submitted to it, the Neutral Firm shall deliver to Phillips and
Duke its determination of the Actual Net Working Capital, which determination
shall be final and binding on the Parties and shall then be deemed such Party's
Actual Net Working Capital. The fees and expenses of the Neutral Firm will be
allocated between Phillips and Duke by the Neutral Firm.

          (d) After a determination of either Party's Actual Net Working Capital
shall have become final and binding on Phillips and Duke as described in Section
3.3(b) above, (i) if such Party's Actual Net Working Capital exceeds zero, the
Company shall pay to such Party such difference, or (ii) if such Party's Actual
Net Working Capital is less than zero, such Party shall pay to the Company the
difference.

          (e) The payments, together with interest thereon from and including
the Closing Date to but excluding such payment date at a rate equal to the rate
of interest from time to time announced publicly by Chase Manhattan Bank as its
prime rate (the "REFERENCE RATE"), will be made within seven days after the
determination of Actual Net Working Capital for both


                                       -13-

Parties has become final and binding as described above and will be made in
immediately available funds by wire transfer to an account designated by the
Person to receive the payment.

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF PHILLIPS

            Phillips hereby represents and warrants to each of Duke and the
Company that, except as disclosed in the Phillips Disclosure Schedule:

          Section 4.1 CORPORATE ORGANIZATION. (a) Phillips and PGC are duly
organized, validly existing and in good standing under the laws of their
respective states of incorporation or organization. Each of Phillips and PGC has
the corporate power and authority to own or lease all of its properties and
assets and to carry on its business as it is now being conducted, and is duly
licensed or qualified to do business in each jurisdiction (whether federal,
state, local or foreign) in which the nature of the business conducted by it or
the character or location of the properties and assets owned or leased by it
makes such licensing or qualification necessary, except where the failure to be
so licensed or qualified, individually or in the aggregate, would not have a
Material Adverse Effect on either Phillips or PGC, as applicable. True and
complete copies of the certificate of incorporation and by-laws of PGC, in
effect as of the date of this Agreement, have previously been made available by
Phillips to Duke.

          (b) Schedule 4.1(b) of the Phillips Disclosure Schedule sets forth a
complete list of all of the Subsidiaries of PGC (each a "PGC SUBSIDIARY" and
collectively, the "PGC SUBSIDIARIES") and their respective jurisdictions of
organization and capitalization and the organizational structure of PGC and its
Subsidiaries (without designating the names or ownership percentages of any
third party owners). All of the outstanding shares of capital stock or limited
liability company interests, as the case may be, of the PGC Subsidiaries are
validly issued, fully paid and non-assessable and are not subject to, nor were
they issued in violation of, any preemptive rights, and, except as set forth in
Schedule 4.1(b) of the Phillips Disclosure Schedule, such shares or limited
liability company interests, as the case may be, are owned by PGC or its
wholly-owned Subsidiaries free and clear of any Lien with respect thereto. Each
PGC Subsidiary (i) is duly organized and validly existing as a corporation or
limited liability company, as the case may be, under the laws of its
jurisdiction of organization, (ii) is duly licensed or qualified to do business
and in good standing in each jurisdiction (whether federal, state, local or
foreign) in which the nature of the business conducted by it or the character or
location of the properties and assets owned or leased by it makes such licensing
or qualification necessary, except where the failure to be so licensed or
qualified, individually or in the aggregate would not have a Material Adverse
Effect on the PGC Subsidiaries, and (iii) has all requisite corporate power and
authority to own or lease its properties and assets and to carry on its business
as now conducted. Except as described above, as of the date of this Agreement
there are not, and at the Closing there will not be, any capital stock, limited
liability company interests or other equity interests in the PGC Subsidiaries
issued or outstanding or any subscriptions, options, warrants, calls, rights,
convertible securities or other agreements or commitments of any character
obligating any PGC Subsidiary to issue, transfer or sell any of its capital
stock or other equity interests, or any agreements, arrangements, or
understandings granting any Person any rights in any PGC Subsidiary similar to
capital stock, limited liability company interests or other

                                       -14-
<PAGE>

equity interests. Except as set forth in Schedule 4.1(b) or 4.10(a)(3) of the
Phillips Disclosure Schedule, neither PGC nor any PGC Subsidiary holds any
interest in any corporation, partnership, joint venture or other entity.

          Section 4.2 AUTHORITY; NO VIOLATION. (a) Phillips has full corporate
power and authority to execute and deliver this Agreement and the Governance
Agreement and to consummate the transactions contemplated by this Agreement and
the Governance Agreement. The execution and delivery of this Agreement and the
Governance Agreement and the consummation of the transactions contemplated by
this Agreement and the Governance Agreement have been duly and validly approved
by all corporate action on the part of Phillips. No other corporate proceedings
on the part of Phillips, GPM Holding or any of the PGC Subsidiaries are
necessary to approve this Agreement or the Governance Agreement and to
consummate the transactions contemplated by this Agreement and the Governance
Agreement. This Agreement has been duly and validly executed and delivered by
Phillips and, assuming due authorization, execution and delivery by Duke and the
Company, constitutes a valid and binding obligation of Phillips, enforceable
against Phillips in accordance with its terms. The Governance Agreement has been
duly and validly executed and delivered by Phillips and, assuming due
authorization, execution and delivery by Duke and the Company, constitutes the
valid and binding obligations of Phillips, enforceable against Phillips in
accordance with its terms.

          (b) At the Closing, (i) PGC shall have good and marketable title to
all of the issued and outstanding limited liability company interests in each
PGC Direct LLC Subsidiary and (ii) PGC or a PGC Subsidiary shall have good and
marketable title to all of the issued and outstanding limited liability company
interests in each PGC Subsidiary, in each case free and clear of any Liens,
restrictions on transfer or voting or preemptive rights. Phillips and PGC have
the full corporate power, right and authority to transfer and convey, or cause
to be transferred and conveyed, to the Company at the Closing the limited
liability company interests in each PGC Direct LLC Subsidiary.

          (c) The execution, delivery and performance of this Agreement and the
Governance Agreement by Phillips do not, and the consummation by Phillips of the
transactions contemplated by this Agreement and the Governance Agreement will
not, (i) constitute a breach or violation of, or a default under, the
certificate of incorporation or by-laws or other organizational documents of
Phillips or PGC, (ii) constitute a breach or violation of, or a default under,
or trigger any "change of control" rights or remedies under, or give rise to any
Lien, any acceleration of remedies, any buy-out right or any right of first
offer or refusal or of termination under, any indenture, license, contract,
agreement or other instrument to which PGC or of any of its Subsidiaries is a
party or by which any of them or their respective properties or assets may be
bound, or (iii) assuming compliance with the applicable requirements of the HSR
Act, violate any law, rule, regulation, judgment, decree or order applicable to
Phillips, PGC or any of the PGC Subsidiaries or any of their respective
properties or assets, except in the case of (ii) and (iii) above for such
breaches, violations, defaults, liens, accelerations or rights as would not
reasonably be expected, individually or in the aggregate, to result in a
Material Adverse Effect on the PGC Subsidiaries or to adversely affect the
ability of Phillips to consummate the transactions contemplated by this
Agreement or the Governance Agreement.

                                       -15-
<PAGE>

          Section 4.3 CONSENTS AND APPROVALS. Except for applicable requirements
of the HSR Act, no notice to, filing with, authorization of, exemption by, or
consent or approval of, or the taking of any other action in respect of any
Governmental Entity or any other Person on the part of Phillips, PGC or the PGC
Subsidiaries is necessary for the consummation by Phillips, PGC or any of the
PGC Subsidiaries of the transactions contemplated by this Agreement, except
where the failure to provide such notice, make such filing, or obtain such
authorization, exemption, consent or approval would not, individually or in the
aggregate, reasonably be expected to result in a Material Adverse Effect on the
PGC Subsidiaries or to adversely affect the ability of Phillips to consummate
the transactions contemplated by this Agreement or the Governance Agreement.

          Section 4.4 PERMITS; COMPLIANCE WITH APPLICABLE LAW. As of the Closing
Date, each of the PGC Subsidiaries shall hold all licenses, franchises,
registrations, permits and authorizations (each, a "PERMIT") necessary for the
lawful conduct of their respective businesses under and pursuant to all, and
have complied with and are not in default under and/or in violation of any,
applicable law, statute, order, rule or regulation of any Governmental Entity
relating to any of the PGC Subsidiaries, except in each case where the failure
to hold such Permit or such noncompliance or default would not, individually or
in the aggregate, have a Material Adverse Effect on the PGC Subsidiaries. To
Phillips' knowledge, the business of the PGC Subsidiaries is not being and has
not been conducted in violation of any applicable law or any order, writ,
injunction or decree of any Governmental Entity, except for any such violations
which would not, individually or in the aggregate, have a Material Adverse
Effect on the PGC Subsidiaries. None of the PGC Subsidiaries has received any
notice or other communication from any Governmental Entity asserting (i) any
violation of law, statute, ordinance, order, rule or regulation, (ii) any
violation of or failure to comply with any term or requirement of any Permit, or
(iii) any revocation, withdrawal, suspension, cancellation, termination or
modification of any Permit, except for violations, failures to comply,
revocations, withdrawals, suspensions, cancellations, terminations or
modifications which would not in the aggregate reasonably be expected to have a
Material Adverse Effect on the PGC Subsidiaries. No notice of any pending
investigation or violation of, noncompliance with or alleged liability under,
any law, statute, ordinance, order, rule, regulation or Permit has been received
by any of the PGC Subsidiaries which would, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect on the PGC
Subsidiaries.

          Section 4.5 FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES. Phillips
has previously made available to Duke true, correct and complete copies of (i)
the audited consolidated balance sheets of PGC and its Subsidiaries as of
December 31, 1998 and 1997 and the related audited consolidated statements of
income and cash flows for the periods then ended and (ii) the unaudited proforma
combined balance sheet of the PGC Subsidiaries (exclusive of income taxes and
with proforma adjustments to eliminate intercompany borrowings) as of September
30, 1999 (the "PGC SEPTEMBER 30 BALANCE SHEET"), a copy of which is attached as
Schedule 4.5 of the Phillips Disclosure Schedule, and the related unaudited
combined statement of income for the nine-month period then ended (together with
the PGC September 30 Balance Sheet, the "PGC SEPTEMBER 30 FINANCIAL
STATEMENTS").

            The financial statements referred to in this Section 4.5 fairly
present (except that, in the case of the PGC September 30 Financial Statements,
such financial statements are

                                       -16-
<PAGE>

incomplete in that they do not include footnotes and do include proforma
adjustments as described above, and subject, in the case of the PGC September 30
Financial Statements, to recurring audit adjustments, none of which either
individually or in the aggregate is material) the results of the consolidated
(or combined) operations and consolidated (or combined) financial positions of
PGC and its Subsidiaries or the PGC Subsidiaries (as adjusted in the manner
described above relating to the PGC September 30 Financial Statements), as the
case may be, for the respective fiscal periods or as of the respective dates
therein set forth. Each of such statements described in this Section 4.5
complies with applicable accounting requirements with respect thereto; and each
of such statements has been prepared in accordance with GAAP (except that, in
the case of the PGC September 30 Financial Statements, such statements are
incomplete in that they do not include footnotes and do include proforma
adjustments as described above) consistently applied during the periods
involved. The PGC Subsidiaries do not have any liabilities required by GAAP to
be set forth on a consolidated balance sheet of the PGC Subsidiaries, except (i)
as set forth on the PGC September 30 Balance Sheet, and (ii) for liabilities
incurred in the ordinary course of business since September 30, 1999 and which
would not have a Material Adverse Effect on the PGC Subsidiaries.

          Section 4.6 BROKER'S FEES. Neither Phillips nor any of its
Subsidiaries (including the PGC Subsidiaries) nor any of their respective
officers or directors has employed any broker or finder or incurred any
liability for any broker's fees, commissions or finder's fees in connection with
the transactions contemplated by this Agreement or the Governance Agreement
which would be payable by the Company, Duke, any Duke Subsidiary or any PGC
Subsidiary.

          Section 4.7 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except for changes
or events consented to or approved by Duke in writing pursuant to Section 6.4,
from September 30, 1999 through the date of this Agreement, the business of the
PGC Subsidiaries has been operated in the ordinary and normal course in all
material respects and there has not been:

          (a) any event (whether covered by insurance or not) which,
individually or in the aggregate, has had or would reasonably be expected to
have a Material Adverse Effect on the PGC Subsidiaries;

          (b) any increase in compensation (including severance or termination
pay) payable to or to become payable to any consultants, officers, directors,
employees or agents working in connection with the business of any PGC
Subsidiary or any change in any insurance, pension or other benefit plan,
payment or arrangement made to, for or with any of such consultants, officers,
directors, employees or agents, in each case other than (i) general increases or
changes reasonably consistent with past practices and applicable to at least 10%
of the employees of Phillips and its Subsidiaries, or (ii) other increases that
are in accordance with past practice and are not material in the aggregate;

          (c) any change in financial accounting methods, principles or
practices by any PGC Subsidiary materially affecting its assets, Liabilities or
businesses, except insofar as may have been required by a change in GAAP;

          (d) any indebtedness for borrowed money incurred by any of the PGC
Subsidiaries other than from Phillips or its Affiliates, any issuance of debt
securities by any of

                                       -17-

the PGC Subsidiaries other than to Phillips or its Affiliates, any assumption,
guarantee, endorsement or other action which would result in any of the PGC
Subsidiaries having responsibility for the obligations of any other Persons, or
any mortgage or encumbrance on properties or assets of any of the PGC
Subsidiaries other than Liens that do not materially restrict or detract from
the value of such properties or assets; or

          (e) any declaration, setting aside or payment of any dividend or any
other similar distribution (other than in cash), directly or indirectly, with
respect to any PGC Subsidiary's securities except as permitted by Section
2.1(e), Section 2.1(f)(ii) or Section 2.1(h).

          Section 4.8 LEGAL PROCEEDINGS. (a) As of the date of this Agreement,
neither Phillips nor PGC nor any of their respective Subsidiaries is a party to
any, and there are no pending or, to Phillips' knowledge, threatened, legal,
administrative, arbitral or other proceedings, claims, actions or governmental
or regulatory investigations of any nature against or otherwise affecting PGC or
any of its Subsidiaries which (i) would reasonably be expected to result in
material injunctive relief or in damages to PGC and its Subsidiaries in excess
of $10,000,000 in the aggregate or (ii) would adversely affect the ability of
Phillips to consummate the transactions contemplated by this Agreement or the
Governance Agreement.

          (b) As of the date of this Agreement, there are no injunctions,
orders, judgments or decrees imposed upon or otherwise affecting PGC or any of
its Subsidiaries or assets which, individually or in the aggregate, have had, or
would reasonably be expected to have, a Material Adverse Effect on the PGC
Subsidiaries.

          Section 4.9  [Intentionally omitted]

          Section 4.10 CONTRACTS. (a) Schedule 4.10(a) of the Phillips
Disclosure Schedule sets forth a true and complete list as of the date of this
Agreement of all contracts, agreements and commitments of the following
categories, whether oral or written, express or implied, to which any of the PGC
Subsidiaries is party or by which any of their respective properties or assets

Governance Agreement) (collectively, the "PGC MATERIAL CONTRACTS"):

               (1) any contract (other than gas purchase agreements) involving
or requiring expenditures or receipts by any PGC Subsidiary of more than
$2,000,000 in any calendar year and not cancelable or terminable within one year

               (3) any partnership or joint venture agreements with regard to
material assets of the PGC Subsidiaries;

               (5) any contract between any of the PGC Subsidiaries, on one
hand, and any Affiliate of Phillips (other than the PGC Subsidiaries), on the
other hand;

               (6) any collective bargaining agreement;

               (7) any employment, personal services, consulting,

involving the delivery or receipt of more than 10,000 mcf per day;

               (9) any contract entered into since January 1, 1996 for the
acquisition or disposition, sale or lease of properties or assets of the PGC

requiring aggregate expenditures or receipts by the PGC Subsidiaries in excess
of $10,000,000; and

               (10) any commitment or agreement to enter into any of the
foregoing.

          (b)  As of the date of this Agreement, each PGC Material Contract is a
valid, binding and enforceable (except as such enforceability may be subject to
any bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or
other laws, now or hereafter in effect, relating to or limiting creditors'
rights generally) obligation of the applicable PGC Subsidiary. As of the date of
this Agreement, there is no default under any PGC Material Contract by any PGC
Subsidiary or, to Phillips' knowledge, by any other party thereto, and no event
has occurred that with the lapse of time or the giving of notice or both would
constitute a default thereunder by any PGC Subsidiary, or to Phillips'
knowledge, any other party, which default or event, individually or in the
aggregate, would reasonably be expected to have a Material Adverse Effect on the
PGC Subsidiaries. As of the date of this Agreement, no party to any PGC Material
Contract has given notice to any PGC Subsidiary or made a claim against any PGC
Subsidiary with respect to any breach or default thereunder which breach or
default, individually or in the aggregate, would reasonably be expected to have
a Material Adverse Effect on the PGC Subsidiaries. As of the date of this
Agreement, there has been no amendment or modification of any of the PGC
Material Contracts except as specifically listed in Schedule 4.10(a) of the
Phillips Disclosure Schedule. The enforceability of any PGC Material Contract
shall not be impaired by the execution and delivery of this Agreement or the
Governance Agreement or the consummation of the transactions contemplated hereby
or thereby, and, as of the date of this Agreement, no PGC Material Contract
requires that a transaction of the kind contemplated by this Agreement or the
Governance Agreement receive the approval of any party to such PGC Material
Contract, except where such impairments or failures to receive approvals,
individually or in the aggregate, would not reasonably be expected to have a
Material Adverse Effect on the PGC Subsidiaries.

agreement, mortgage, indenture, security agreement or other agreement or
instrument relating to the borrowing of money by, or any extension of credit to,
any of the PGC Subsidiaries.

          (d) As of the date of this Agreement, Phillips has delivered to Duke

record, by the PGC Subsidiaries as of the date of this Agreement and which are
material to the business of the PGC Subsidiaries.

          (b) REALTY LEASES. As of the date of this Agreement, with respect to
all leases of real property of or used by the PGC Subsidiaries (collectively,

not otherwise, subject to Permitted Encumbrances. Schedule 4.11(b) of the
Phillips Disclosure Schedule identifies all leases of real property, other than
easements and rights of way, a leasehold interest in which is owned,
beneficially and/or of record, by the PGC Subsidiaries as of the date of this
Agreement and which are material to the business of the PGC Subsidiaries. Except
as otherwise set forth in Schedule 4.11(b) of the Phillips Disclosure Schedule,
as of the date of this Agreement each of the PGC Leases is a valid, binding and
enforceable (except as such enforceability may be subject to any bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or other laws, now
or hereafter in effect, relating to or limiting creditors' rights generally)
obligation of each of the lessee and of the lessor under such PGC Lease. As of
the date of this Agreement, except where, individually or in the aggregate,
there would not reasonably be expected to be a Material Adverse Effect on the
PGC Subsidiaries or as otherwise set forth in Schedule 4.11(b) of the Phillips

expiration of such PGC Lease by reason of a breach or alleged breach by the
tenant thereunder.

properties, operations and activities of the PGC Subsidiaries have been and are
in compliance with all applicable Environmental Laws; (ii) the PGC Subsidiaries
are not subject to any existing, pending or, to Phillips' knowledge, threatened,

review of and copying by Duke all of the environmental reports, documents, data

they apply to any property, operation, activity or PGC Subsidiary prior to the
date such property, operation, activity or PGC Subsidiary became owned or
controlled, directly or indirectly, by Phillips, shall be limited to Phillips'
knowledge.

          Section 4.13 INTELLECTUAL PROPERTY. (a) As of the date of this

States or foreign (collectively, the "PGC INTELLECTUAL PROPERTY"), as are
necessary to permit the PGC Subsidiaries to conduct their business as currently
conducted, except where the failure to have such ownership, license or right to
use would not, individually or in the aggregate, have a Material Adverse Effect
on the PGC Subsidiaries.

          (b) As of the date of this Agreement, (i) to Phillips' knowledge,
neither the use of the PGC Intellectual Property nor the conduct of the business
of the PGC Subsidiaries as currently conducted infringes the intellectual
property rights of any third party and there are no present or threatened
infringements of the PGC Intellectual Property by any third party, except, in
either case, for such infringements which would not, individually or in the

and assessment of the Year 2000 Problem, have developed a plan for addressing
the Year 2000 Problem on a timely basis and have to date implemented such plan,

          Duke hereby represents and warrants to each of Phillips and the
Company that, except as disclosed in the Duke Disclosure Schedule:

organized, validly existing and in good standing under the laws of their
respective states of incorporation or organization. Each of Duke and DEFS
Holding has the corporate power and authority to own or lease all of its
properties and assets and to carry on its business as it is now being conducted,
and is duly licensed or qualified to do business in each jurisdiction (whether
federal, state, local or foreign) in which the nature of the business conducted
by it or the character or location of the properties and assets owned or leased
by it makes such licensing or qualification necessary, except where the failure
to be so licensed or qualified, individually or in the aggregate, would not have
a Material Adverse Effect on either Duke or DEFS Holding, as applicable. True
and complete copies of the certificate of incorporation and by-laws of DEFS
Holding, in effect as of the date of this Agreement, have previously been made
available by Duke to Phillips.

          (b) Schedule 5.1(b) of the Duke Disclosure Schedule sets forth a
complete list of all Subsidiaries of DEFS Holding (together with DETTCO and any
Subsidiary of DETTCO, each a "DEFS SUBSIDIARY" and collectively, the "DEFS
SUBSIDIARIES") and their respective jurisdictions of organization and
capitalization and the organizational structure of DEFS Holding and its
Subsidiaries (without designating the names or ownership percentages of any
third party owners). All of the outstanding shares of capital stock or limited
liability company interests, as

                                       -24-

the case may be, of each of the DEFS Subsidiaries are validly issued, fully paid
and non-assessable and are not subject to, nor were they issued in violation of,
any preemptive rights. Except as set forth in Schedule 5.1(b) of the Duke
Disclosure Schedule, and except with respect to DETTCO and its Subsidiaries,
such shares or limited liability company interests, as the case may be, are
owned by DEFS Holding or its wholly-owned Subsidiaries free and clear of any
Lien with respect thereto. At the Closing, all of the outstanding shares of
capital stock or limited liability company interests of DETTCO will be owned by
DEFS free and clear of any Lien with respect thereto and all of the outstanding
shares of capital stock or limited liability company interests of any Subsidiary
of DETTCO will be owned by DETTCO free and clear of any Lien with respect

corporation or limited liability company, as the case may be, under the laws of
its jurisdiction of organization, (ii) is duly licensed or qualified to do
business and in good standing in each jurisdiction (whether federal, state,
local or foreign) in which the nature of the business conducted by it or the
character or location of the properties and assets owned or leased by it makes

licensed or qualified, individually or in the aggregate, would not have a
Material Adverse Effect on DEFS, and (iii) has all requisite corporate power and
authority to own or lease its properties and assets and to carry on its business
as now conducted. Except as described above, as of the date of this Agreement
there are not, and at the Closing there will not be, any capital stock, limited
liability company interests or other equity interests in the DEFS Subsidiaries
issued or outstanding or any subscriptions, options, warrants, calls, rights,
convertible securities or other agreements or commitments of any character
obligating any DEFS Subsidiary to issue, transfer or sell any of its capital
stock or other equity interests, or any agreements, arrangements, or
understandings granting any Person any rights in any DEFS Subsidiary similar to
capital stock, limited liability company interests or other equity interests.
Except as set forth in Schedule 5.1(b) or 5.10(a)(3) of the Duke Disclosure
Schedule, no DEFS Subsidiary holds any interest in any corporation, partnership,
joint venture or other entity.

has full corporate power and authority to execute and deliver this Agreement and
the Governance Agreements and to consummate the transactions contemplated by
this Agreement and the Governance Agreement (except that the board of directors
of the Company has not approved the IPO). The execution and delivery of this
Agreement and the Governance Agreement and the consummation of the transactions
contemplated by this Agreement and the Governance Agreement have been duly and
validly approved by all corporate action on the part of each of Duke and the

Holding, the DEFS Subsidiaries or the Company are necessary to approve this
Agreement or the Governance Agreement and to consummate the transactions
contemplated by this Agreement and the Governance Agreement (except that the
board of directors of the Company has not approved the IPO). This Agreement has
been duly and validly executed and delivered by each of Duke and the Company
and, assuming due authorization, execution and delivery by Phillips, constitutes
a valid and binding obligation of each of Duke and the Company, enforceable
against each of Duke and the Company in accordance with its terms. The
Governance Agreement has been duly and validly executed and delivered by each of
Duke and the Company and, assuming due authorization, execution and delivery by

          (c) The execution, delivery and performance of this Agreement and the
Governance Agreement by Duke do not, and the consummation by Duke of the
transactions contemplated by this Agreement and the Governance Agreement will
not, constitute (i) a breach or violation of, or a default under, the
certificate of incorporation or by-laws or other organizational documents of
Duke or DEFS Holding, (ii) constitute a breach or violation of, or a default
under, or trigger any "change of control" rights or remedies under, or give rise
to any Lien, any acceleration of remedies, any buy-out right, or any right of
first offer or refusal or of termination under, any indenture, license,
contract, agreement or other instrument to which DEFS Holding or of any of its
Subsidiaries is a party or by which any of them or their respective properties
or assets may be bound, or (iii) assuming compliance with the applicable
requirements of the HSR Act, violate any law, rule, regulation, judgment, decree
or order applicable to Duke, DEFS Holding or any of the DEFS Subsidiaries or any
of their respective properties or assets, except in the case of (ii) and (iii)
above for such breaches, violations, defaults, liens, accelerations or rights as
would not reasonably be expected, individually or in the aggregate, to result in
a Material Adverse Effect on DEFS or to adversely affect the ability of Duke to
consummate the transactions contemplated by this Agreement or the Governance
Agreements.

          Section 5.3 CONSENTS AND APPROVALS. Except for applicable requirements
of the HSR Act, no notice to, filing with, authorization of, exemption by, or
consent or approval of, or the taking of any other action in respect of any
Governmental Entity or any other Person on the part of Duke, DEFS Holding, or
the DEFS Subsidiaries is necessary for the consummation by Duke, DEFS Holding,
or any of the DEFS Subsidiaries of the transactions contemplated by this
Agreement, except where the failure to provide such notice, make such filing, or
obtain such authorization, exemption, consent or approval would not,
individually or in the aggregate, reasonably be expected to result in a Material
Adverse Effect on DEFS or to adversely affect the ability of Duke to consummate
the transactions contemplated by this Agreement or the Governance Agreement.

          Section 5.4 PERMITS; COMPLIANCE WITH APPLICABLE LAW. As of the Closing
Date, each of the DEFS Subsidiaries shall hold all Permits necessary for the
lawful conduct of their respective businesses under and pursuant to all, and
have complied with and are not in default under and/or in violation of any,
applicable law, statute, order, rule or regulation of any Governmental Entity
relating to any of the DEFS Subsidiaries, except in each case where the failure
to hold such Permit or such noncompliance or default would not, individually or
in the aggregate, have a Material Adverse Effect on DEFS. To Duke's knowledge,
the business of the DEFS Subsidiaries is not being and has not been conducted in
violation of any applicable law or any order, writ, injunction or decree of any
Governmental Entity, except for any such violations

                                       -26-
<PAGE>

which would not, individually or in the aggregate, have a Material Adverse
Effect on DEFS. None of the DEFS Subsidiaries has received any notice or other
communication from any Governmental Entity asserting (i) any violation of law,
statute, ordinance, order, rule or regulation, (ii) any violation of or failure
to comply with any term or requirement of any Permit, or (iii) any revocation,
withdrawal, suspension, cancellation, termination or modification of any Permit,
except for violations, failures to comply, revocations, withdrawals,
suspensions, cancellations, terminations or modifications which would not in the
aggregate reasonably be expected to have a Material Adverse Effect on DEFS. No
notice of any pending investigation or violation of, non-compliance with or
alleged liability under, any law, statute, ordinance, order, rule, regulation or
Permit has been received by any of the DEFS Subsidiaries which would,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on DEFS.

          Section 5.5 FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES. Duke has
previously made available to Phillips true, correct and complete copies of (i)
the audited combined balance sheets of DEFS and its Subsidiaries, DETTCO and
Subsidiaries, Panhandle Field Services, Inc., and Panhandle Gathering Company as
of December 31, 1998 and 1997 and the related audited combined statements of
income and cash flows for the periods then ended (such statements include the
investment in TEPPCO which is an Excluded Asset) and (ii) the unaudited proforma
combined balance sheet of DEFS and its Subsidiaries (with proforma adjustments
to eliminate intercompany advances, notes, income taxes, and the investment in
TEPPCO and to include DETTCO, Canrock and goodwill related to Mega) as of
September 30, 1999 (the "DEFS SEPTEMBER 30 BALANCE SHEET"), a copy of which is
attached as Schedule 5.5 of the Duke Disclosure Schedule, and the related
unaudited combined statement of income for the nine-month period then ended
(together with the DEFS September 30 Balance Sheet, the "DEFS SEPTEMBER 30
FINANCIAL STATEMENTS").

            The financial statements referred to in this Section 5.5 fairly

not include footnotes, and subject, in the case of the DEFS September 30
Financial Statements, to recurring audit adjustments, none of which either
individually or in the aggregate is material) the results of the combined
operations and combined financial positions of DEFS and its Subsidiaries (as
adjusted in the manner described above relating to the DEFS September 30
Financial Statements) for the respective fiscal periods or as of the respective
dates therein set forth. Each of such statements described in this Section 5.5
complies with applicable accounting requirements with respect thereto; and each
of such statements has been prepared in accordance with GAAP (except that such
statements are incomplete in that they do not include footnotes and do include
proforma adjustments as described above) consistently applied during the periods
involved. Neither DEFS nor any of its Subsidiaries (as adjusted in the manner
described above) has any liabilities required by GAAP to be set forth on a
combined balance sheet of DEFS and its Subsidiaries, except (i) as set forth on
the DEFS September 30 Balance Sheet, and (ii) for liabilities incurred in the
ordinary course of business since September 30, 1999 and which would not have a
Material Adverse Effect on DEFS.

          Section 5.6 BROKER'S FEES. Neither Duke nor any of its Subsidiaries
(including DEFS Holding and its Subsidiaries) nor any of their respective
officers or directors has employed

                                       -27-
<PAGE>

commissions or finder's fees in connection with the transactions contemplated by
this Agreement or the Governance Agreement which would be payable by the
Company, Phillips, any Phillips Subsidiary or any DEFS Subsidiary.

          Section 5.7 ABSENCE OF CERTAIN CHANGES OR EVENTS. Except for changes
or events consented to or approved by Phillips in writing pursuant to Section
6.5, from September 30, 1999 through the date of this Agreement, the business of
the DEFS Subsidiaries has been operated in the ordinary and normal course in all
material respects and there has not been:

          (a) any event (whether covered by insurance or not) which,
individually or in the aggregate, has had or would reasonably be expected to
have a Material Adverse Effect on DEFS;

          (b) any increase in compensation (including severance or termination
pay) payable to or to become payable to any consultants, officers, directors,
employees or agents working in connection with the business of any DEFS
Subsidiary or any change in any insurance, pension or other benefit plan,

directors, employees or agents, in each case other than (i) general increases or
changes reasonably consistent with past practices and applicable to at least 10%
of the employees of Duke and its Subsidiaries, or (ii) other increases that are
in accordance with past practice and are not material in the aggregate;

          (c) any change in financial accounting methods, principles or
practices by any DEFS Subsidiary materially affecting its assets, Liabilities or
businesses, except insofar as may have been required by a change in GAAP;

          (d) any indebtedness for borrowed money incurred by any of the DEFS
Subsidiaries other than from Duke or its Affiliates, any issuance of debt
securities by any of the DEFS Subsidiaries other than to Duke or its Affiliates,
any assumption, guarantee, endorsement or other action which would result in any
of the DEFS Subsidiaries having responsibility for the obligations of any other
Persons, or any mortgage or encumbrance on properties or assets other than Liens
that do not materially restrict or detract from the value of such properties or
assets; or

          (e) any declaration, setting aside or payment of any dividend or any
other similar distribution (other than in cash), directly or indirectly, with
respect to any DEFS Subsidiary's securities except as permitted by Section
2.1(b)(i), Section 2.1(d), Section 2.1(f) or Section 2.1(g).

          Section 5.8 LEGAL PROCEEDINGS. (a) As of the date of this Agreement,
neither Duke nor DEFS Holding nor any of their respective Subsidiaries is a
party to any, and there are no pending or, to Duke's knowledge, threatened,
legal, administrative, arbitral or other proceedings, claims, actions or
governmental or regulatory investigations of any nature against or otherwise
affecting DEFS Holding or any of its Subsidiaries which (i) would reasonably be
expected to result in material injunctive relief or in damages to DEFS Holding
and its Subsidiaries in excess of $10,000,000 in the aggregate or (ii) would
adversely affect the ability

                                       -28-
<PAGE>

of Duke to consummate the transactions contemplated by this Agreement or the
Governance Agreement.

<PAGE>

               (9) any contract entered into since January 1, 1996 for the

of this Agreement, there is no default under any DEFS Material Contract by any
DEFS Subsidiary or, to Duke's knowledge, by any other party thereto, and no
event has occurred that with the lapse of time or the giving of notice or both

execution and delivery of this Agreement or the Governance Agreement or the
consummation of the transactions contemplated hereby or thereby, and, as of the
date of this Agreement, no DEFS Material Contract requires that a transaction of

would not reasonably be expected to have a Material Adverse Effect on DEFS.

for the acquisitions set forth in Schedule 6.5(e) of the Duke Disclosure

          (f) except as contemplated by DEFS's 2000 capital expenditure
forecasts set forth in Schedule 6.5(f) of the Duke Disclosure Schedule, and
except for acquisitions permitted under Section 6.5(c), none of the DEFS

          (h) except as contemplated in Section 2.1(b)(i), Section 2.1(d),

indirectly, with respect to securities of any DEFS Subsidiary;

          (i) except where the applicable DEFS Subsidiary is in good faith
contesting the same (with appropriate reserves), none of the DEFS Subsidiaries
shall fail to pay when due (i) any trade accounts payable or (ii) any payments
required by any indentures, mortgages, financing arrangements, loan agreements

shall agree to take any action prohibited by this Section 6.5.

           Notwithstanding the provisions of this Section 6.5, nothing in this
Agreement or the Governance Agreement shall be construed or interpreted to
prevent the DEFS Subsidiaries from (i) paying or making regular or special
dividends or other distributions consisting of cash, (ii) making or accepting
inter or intra company advances to, from or with one another or with Duke or any
of its Affiliates or (iii) engaging in any transaction incident to the normal
cash management procedures of Duke and its Affiliates prior to the Closing,
PROVIDED that as of the Closing, the Net Working Capital of the DEFS
Subsidiaries shall equal zero.

          Section 6.6 PRESERVATION OF BUSINESS. (a) Subject to the terms and
conditions of this Agreement and the Governance Agreement, Duke shall, and shall
cause the DEFS Subsidiaries to, use reasonable efforts to preserve the business
of the DEFS Subsidiaries intact, to keep available to the DEFS Subsidiaries and
the Company the services of the DEFS Employees and to preserve the goodwill of
customers and others having business relations with the DEFS Subsidiaries in all
material respects.

          (b) Subject to the terms and conditions of this Agreement and the
Governance Agreement, Phillips shall, and shall cause the PGC Subsidiaries to,
use reasonable efforts to preserve the business of the PGC Subsidiaries intact,
to keep available to the PGC Subsidiaries

                                       -40-
<PAGE>

and the Company the services of the PGC Employees and to preserve the goodwill
of customers and others having business relations with the PGC Subsidiaries in
all material respects.

          (c) Prior to the Closing, Duke shall cause the DEFS Subsidiaries to
consummate the sale and disposition of their interest in that certain
partnership identified on the Duke Disclosure Schedule as the General
Partnership for Westana Gathering Company.

          Section 6.7 PUBLIC ANNOUNCEMENTS. Except as otherwise required by law,
each of Duke and Phillips will consult with the other and obtain the consent of
the other (which consent shall not be unreasonably withheld or delayed) before
issuing, or permitting any agent or Affiliate to issue, any press releases or
otherwise making or permitting any agent or Affiliate to make, any public
statements with respect to this Agreement or the Governance Agreement or the
transactions contemplated hereby and thereby.

          Section 6.8 PGC EASEMENTS. (a) For purposes of this Agreement, all of
the PGC Easements shall be classified as either "PGC Single-User Easements" or
"PGC Multiple-User Easements". Phillips holds legal title to numerous PGC
Easements for the benefit of the PGC Subsidiaries (or, in the case of certain
PGC Multiple-User Easements, for the joint benefit of one or more PGC
Subsidiaries, with respect to certain existing pipelines used in connection with
such PGC Subsidiaries' business, and Phillips, with respect to the remainder of
such PGC Multiple-User Easement). In addition, the PGC Subsidiaries hold legal
title to certain PGC Multiple-User Easements for the joint benefit of Phillips,
with respect to certain existing pipelines used in connection with Phillips'
business, and a PGC Subsidiary, with respect to the remainder of such PGC
Multiple-User Easement. Duke and the Company acknowledge and agree that it will
not be feasible prior to Closing to effect comprehensive assignments of record
legal title with respect to all of the PGC Single-User Easements, or all of the
partial easement rights ("PGC PARTIAL EASEMENT RIGHTS") in PGC Multiple-User
Easements held by Phillips for the benefit of the PGC Subsidiaries, nor will it
be feasible prior to Closing to effect comprehensive assignments of legal title
with respect to all of the partial easement rights ("PHILLIPS PARTIAL EASEMENT
RIGHTS") in PGC Multiple-User Easements owned by the PGC Subsidiaries for the
benefit of Phillips.

          (b) Accordingly, (i) at or prior to the Closing, Phillips shall assign
to the PGC Subsidiaries all of Phillips' beneficial interest in all PGC
Single-User Easements and all PGC Partial Easement Rights in PGC Multiple-User
Easements owned by Phillips; (ii) at or prior to the Closing, Phillips shall
cause the PGC Subsidiaries to assign to Phillips all of the beneficial interest
in all Phillips Partial Easement Rights in PGC Multiple-User Easements owned by
the PGC Subsidiaries; (iii) subsequent to the Closing, Phillips will continue to
hold record legal title to those PGC Single-User Easements described in the
second sentence of Section 6.8(a) (and all PGC Partial Easement Rights in each
PGC Multiple-User Easement held by Phillips) for the use and benefit of the
affected PGC Subsidiary, and otherwise upon and subject to the applicable
provisions of this Section 6.8, until such time as record legal title to such
PGC Single-User Easement or such PGC Partial Easement Rights, as the case may
be, shall have been assigned to a PGC Subsidiary pursuant to Section 6.8(d)
hereof; and (iv) subsequent to the Closing, the applicable PGC Subsidiaries will
continue to hold legal title to all Phillips Partial Easement Rights in each PGC
Multiple-User Easement owned by any PGC Subsidiary for the use and benefit of
Phillips, and otherwise upon and subject to the applicable provisions of this

                                       -41-
<PAGE>

Section 6.8, until such time as record legal title to such Phillips Partial
Easement Rights shall have been assigned to Phillips pursuant to Section 6.8(h)
hereof.

          (c) In connection with any PGC Single-User Easement (or any PGC
Partial Easement Rights in a PGC Multiple-User Easement held by Phillips) to
which Phillips, pursuant to this Section 6.8, shall retain legal title
subsequent to the Closing for the benefit (in whole or part) of any PGC
Subsidiary (each a "PHILLIPS RETAINED EASEMENT"), Phillips shall hold such
Phillips Retained Easement and exercise and enforce its rights thereunder for
the use and benefit of, and in such manner as may be reasonably directed by, the
appropriate PGC Subsidiary. Without limiting the generality of the foregoing,
Phillips shall not, without the prior written consent of the Company in each
instance, execute any document or instrument, or take any other affirmative
action, that is intended or could reasonably be expected to have the effect of
terminating, surrendering, canceling, revoking, limiting, rescinding or
otherwise impairing or interfering with any such Phillips Retained Easement, or
the rights, privileges and benefits of any PGC Subsidiary with respect thereto,
including any assignment or other disposition of any such Phillips Retained
Easement in favor of any Person other than the Company or a PGC Subsidiary. In
connection with Phillips Retained Easement, Duke and Phillips agree as follows:

          (i)   Phillips shall indemnify, defend and hold harmless the Company
     and its Subsidiaries from and against any and all Damages, excluding
     consequential and punitive Damages, suffered or incurred by the Company or
     such Subsidiaries after Closing as a result of the failure of Phillips to
     have assigned such Phillips Retained Easement to the PGC Subsidiaries by
     the Closing Date (all necessary third party consents having been obtained);
     PROVIDED, HOWEVER, that such indemnity shall not extend to any Damages
     resulting from or attributable to the failure or inability of the Company
     to obtain financing for the transactions contemplated by this Agreement.

          (ii)  The Company shall indemnify, defend and hold harmless Phillips
     and the Phillips Retained Affiliates from and against any and all Damages,
     excluding consequential and punitive Damages, suffered or incurred by such
     entities after Closing in respect of such Phillips Retained Easement to the
     extent such Damages consist of Subject Easement Liabilities that the
     Company would have been responsible for, had such Phillips Retained
     Easement been assigned to the PGC Subsidiaries by the Closing Date (all
     necessary third party consents having been obtained).

As used in this Section 6.8(c), the term "SUBJECT EASEMENT LIABILITIES" shall
mean, with respect to a Phillips Retained Easement, any and all payment
obligations to third parties, including lease rentals, renewal fees, ad valorem
and other taxes, arising and relating to the period from and after Closing in
respect of such Phillips Retained Easement.

          (d) Prior to the Closing, Phillips, in consultation with the Company,
shall develop a timetable and action plan pursuant to which record legal title
to all of the PGC Single-User Easements (and all of the PGC Partial Easement
Rights in PGC Multiple-User Easements) which are to be held by Phillips
subsequent to the Closing for the benefit of the PGC Subsidiaries will be
assigned of record to the PGC Subsidiary whose related pipelines or equipment
make use of such PGC Single-User Easements (or such PGC Partial Easement Rights,
as the case may be) as expeditiously as is reasonably practicable, but in any
event not later than

                                       -42-
<PAGE>

the applicable date stated in Section 6.8(e) (as extended pursuant to the terms
hereof, the "EASEMENT ASSIGNMENT DEADLINE"). Subsequent to the Closing, all of
such PGC Single-User Easements (and all of such PGC Partial Easement Rights in
PGC Multiple-User Easements) shall, subject to the provisions of the last
sentence of Section 6.8(e) hereof, be assigned to the applicable PGC Subsidiary
in accordance with such timetable and action plan. Each assignment of legal
title to a PGC Single-User Easement (or any PGC Partial Easement Rights in a PGC
Multiple-User Easement, as the case may be) shall be by special warranty
assignment in recordable form customary for the state in which the property
affected by such PGC Single-User Easement or PGC Multiple-User Easement is
located, and shall be without warranty of title or completeness other than a
special warranty of title as against those claiming by, through, or under
Phillips and not otherwise, and subject to Permitted Encumbrances. Counsel for
the Company shall have the right to monitor Phillips' process of preparing such
assignments and the property descriptions therefor from time to time at
Phillips' offices. Such counsel shall also have the right to review selected
samples of such assignments and descriptions to check whether same accurately
reflect the contents of Phillips' files. All such assignments and descriptions
shall be reasonably satisfactory to the Company and its counsel. Phillips shall
cause each such special warranty assignment to be filed of record in the
appropriate land title recording office, and shall pay all recording fees, deed
stamp taxes and other costs incurred in connection with such recordation.
Phillips shall use reasonable efforts to complete such assignments in the order
of the relative value of the applicable PGC Easements, with the most valuable
PGC Easements to be assigned first; PROVIDED, HOWEVER, that nothing contained in
this sentence shall be construed as requiring Phillips to assign any PGC
Gathering Easement prior to the Easement Assignment Deadline for the PGC
Trunkline Easements as set forth in Section 6.8(e) (as each such term is
hereinafter defined). If requested to do so by the Company, Phillips shall use
reasonable efforts to change the order in which PGC Single-User Easements (and
PGC Partial Easement Rights) are scheduled to be assigned pursuant to this
Section 6.8 to accommodate the business requirements of the Company; PROVIDED,
HOWEVER, that if the Company shall request Phillips to defer the assignment of
any PGC Trunkline Easement until after the assignment of any PGC Gathering
Easement (including, without limitation, under the circumstances described in
Section 6.8(f) hereof), then the Easement Assignment Deadline specified in
Section 6.8(e) with respect to the PGC Trunkline Easements shall be extended as
to such PGC Trunkline Easement to the extent reasonably necessary to enable
Phillips to comply with such request.

          (e) The PGC Easements relating to the pipelines identified in Schedule
6.8(e) annexed to this Agreement are herein called the "PGC TRUNKLINE
EASEMENTS". The PGC Easements, other than the PGC Trunkline Easements, are
herein called the "PGC GATHERING EASEMENTS". With respect to the PGC Trunkline
Easements for which legal title is to be assigned subsequent to the Closing
pursuant to Section 6.8(d), the applicable Easement Assignment Deadline is 120
days following the date of this Agreement, subject to the provisions of the last
sentence of this Section 6.8(e). With respect to the PGC Gathering Easements for
which record legal title is to be assigned subsequent to the Closing pursuant to
Section 6.8(d), the applicable Easement Assignment Deadline is 14 months from
the date of this Agreement subject to the provisions of the last sentence of
this Section 6.8(e). Not later than 30 days after each of the Easement
Assignment Deadlines, Phillips shall furnish the Company a certificate of a duly
authorized officer of Phillips, certifying that the obligations of Phillips
required to have been performed on or prior to such Easement Assignment Deadline
have been complied with in all material respects as of the date of such
officer's certificate, or to the extent that such certification cannot


                                       -43-
<PAGE>

accurately be made, specifying the reasons therefor; PROVIDED that no such
certificate shall affect Phillips' obligations or the Company's rights under the
other provisions of this Section 6.8. Notwithstanding anything appearing to the
contrary in Section 6.8(d) hereof or in this Section 6.8(e), with respect to any
Phillips Retained Easement the assignment of which requires the consent or
approval of any Governmental Entity or other third party, (i) the Easement
Assignment Deadline for such Phillips Retained Easement that would otherwise be
applicable to such Phillips Retained Easement but for the operation of this
sentence shall be extended by 60 days in the case of a PGC Trunkline Easement
and 90 days in the case of a PGC Gathering Easement, but in each case no later
than that date which is 30 calendar days after such consent or approval shall
have been obtained; and (ii) Phillips shall continue subsequent to the Closing
to use commercially reasonable efforts to obtain such consent or approval.

          (f) At any time following Closing but prior to the applicable Easement
Assignment Deadline, the Company may notify Phillips in writing that the
Company, because of significant business needs or opportunities of the Company
as to which time is of the essence (as determined in good faith by the General
Counsel of the Company), requires Phillips to complete promptly the transfer of
record legal title to the PGC Subsidiaries of specified Phillips Retained
Easements identified by the Company as being directly involved in such business
needs or opportunities. If Phillips fails to complete such transfer within 30
days following such notice, the Company shall have the right, but not the
obligation, to take such of the following actions as it reasonably deems
necessary or appropriate to remedy such failure ("EASEMENT CURATIVE ACTIONS"):
(i) the preparation of an assignment (conforming to the requirements set forth
in Section 6.8(d)hereof) for the applicable Phillips Retained Easement, (ii) the
payment of any amounts required to be paid to a third party for the granting of
any consents required for such assignment, (iii) obtaining a new easement for
the existing pipeline, (iv) provided that none of the other Easement Curative
Actions are reasonably likely, in the good faith opinion of the Company, to
remedy such failure, obtaining an easement for a replacement pipeline and laying
a pipeline in such easement; and (v) such other actions as are reasonable under
the circumstances. Phillips shall give the Company and its representatives
reasonable access to any records in the possession of Phillips or its
Subsidiaries necessary for the Company to prepare such assignments and property
descriptions therefor, PROVIDED such access does not unreasonably interfere with
any significant business need or opportunity as to which time is of the essence.
Within 20 days following request, Phillips shall reimburse the Company for all
commercially reasonable costs incurred by the Company for the Easement Curative
Actions (including reimbursement for Company personnel time at their normal
hourly rates). The provisions of this Section 6.8(f) shall not limit the
indemnification obligations of Phillips under Section 6.8(c).

          (g) With respect to any Phillips Retained Easements that (i) have not
been transferred to the applicable PGC Subsidiary as of the applicable Easement
Assignment Deadline due to the failure to obtain a Governmental Entity or other
third party consent and (ii) with respect to which Phillips shall have
diligently used commercially reasonable efforts to obtain such consent during
the period beginning on the date hereof and ending on the applicable Easement
Assignment Deadline and Phillips agrees to provide the Company a summary of its
efforts in that regard to date, Duke and Phillips agree as follows:

          (i)   Phillips shall have the right, for a period of 10 days following
     such Easement Assignment Deadline, to approach the Company and propose any
     lawful

                                       -44-
<PAGE>

     arrangements (including an extension of the Easement Assignment Deadline)
     that Phillips believes will ultimately lead to the receipt of the
     applicable unobtained consent within a reasonable period of time or
     eliminate (in a lawful way) the need therefor, in either case without
     exposing the Company to any undue risks;

          (ii)  The Company shall consider any such proposals in good faith and
     shall act in a commercially reasonable manner (considering the interests of
     both parties) in deciding whether to accept or reject any such proposal;
     and

          (iii) For so long as the Company is considering any such proposal made
     by Phillips, the Company will refrain from exercising its rights under the
     remaining provisions of this Section 6.8(g) with respect to the applicable
     PGC Easement.

Subject to the preceding provisions of this Section 6.8(g), at any time
following the applicable Easement Assignment Deadline, the Company may take one
or more Easement Curative Actions with respect to any PGC Easements which shall
not have been transferred by such Easement Assignment Deadline (without regard
to the existence of any significant business need or opportunity as to which
time is of the essence) and, in such event, the Company and Phillips shall have
the same rights and obligations as stated in Section 6.8(f) with respect to such
Easement Curative Actions; provided, however, that the Company may take the
Easement Curative Actions described in clauses (i) and (ii) of the third
sentence of Section 6.8(f) upon prior written notice to Phillips even in the
absence of commercially reasonable business needs of the Company or a PGC
Subsidiary, and nevertheless Phillips shall reimburse the Company for its
reasonable costs incurred in connection with the taking of the Easement Curative
Actions. Each of Duke and the Company acknowledges and agrees that its remedies
against Phillips for any failure on the part of Phillips to complete the
transfer of legal title to any PGC Easement by the applicable Easement
Assignment Deadline, or any earlier date required under Section 6.8(f) (but not
its other obligations under this Section 6.8), shall be limited exclusively to
(A) seeking indemnification upon and subject to the terms, conditions and
limitations set forth in Section 6.8(c), and (B) taking one or more of the
Easement Curative Actions described in clauses (i) through (v) of Section 6.8(f)
hereof, upon and subject to the terms, conditions and limitations set forth in
Section 6.8(f) or this Section 6.8(g), as applicable.

          (h) As expeditiously as is reasonably practicable, but in any event
not later than that date which is nine months after the Closing, record legal
title to all of the Phillips Partial Easement Rights which are held by any PGC
Subsidiaries subsequent to the Closing for the benefit of Phillips shall be
assigned of record to Phillips or the Phillips Retained Affiliate designated by
Phillips. Each assignment of record legal title to any Phillips Partial Easement
Rights in a PGC Multiple-User Easement shall be by special warranty assignment
in recordable form customary for the state in which the property affected by
such PGC Multiple-User Easement is located, and shall be without warranty of
title or completeness other than a special warranty of title as against those
claiming by, through, or under the Company or any PGC Subsidiary and not
otherwise, and subject to Permitted Encumbrances. Phillips shall prepare forms
of assignment and the property descriptions therefor and furnish the same for
review and approval by the Company and its counsel, such approval not to be
unreasonably withheld or delayed. Phillips shall cause each such special
warranty assignment to be filed of record in the appropriate land title
recording office, and shall pay all recording fees, deed stamp taxes and

                                       -45-
<PAGE>

other costs incurred in connection with such recordation. If requested to do so
by Phillips, the Company and the PGC Subsidiaries shall use reasonable efforts
to schedule the assignment of Phillips Partial Easement Rights pursuant to this
Section 6.8(h) so as to accommodate the business requirements of Phillips.

          (i) The instrument creating any PGC Multiple-User Easement may give
the easement holder the right to lay one or more additional pipelines on and
across the servient tenement. The partial assignment of such easement to be
completed pursuant to the provisions of this Section 6.8 shall provide that (i)
both assignor and assignee shall have the right to lay a replacement pipeline
and (ii) either assignor or assignee (but not both) shall have the right to lay
additional pipelines (unless expressly permitted by the provisions of the
instrument creating such easement). The party (as between assignor and assignee)
to receive such right to lay additional pipelines (the "ADDITIONAL LINE PARTY")
shall be (i) the party with the greater number of existing pipelines across the
easement or (ii) if each party has the same number of existing pipelines across
the easement, the party who has the greater demonstrated need (present or
projected future over a period of three years) for additional pipeline capacity
at such location. The determination of each party's "demonstrated need" for
additional pipeline capacity shall be on a case-by-case basis. The Company and
Phillips shall share information and attempt to reach agreement as promptly as
possible with respect to each such PGC Easement. If, however, such parties fail
to reach agreement within ten (10) days after written notice given by either
party to the other, then the issue of which party shall be the Additional Line
Party for a particular PGC Easement shall be submitted to a mutually agreeable
third party whose determination shall be binding on the Company and Phillips. At
any time and from time to time following the execution and delivery of a partial
assignment, the Additional Line Party shall consider and accommodate where
lawful and feasible consistent with the Additional Line Party's needs, a request
by the other party to the partial assignment and to the extent permitted
pursuant to the provisions of the underlying easement instrument and applicable
law, for a grant to such other party of the right to lay an additional pipeline
on and across the servient tenement or the establishment of an agency,
subcontracting, sublicensing or subleasing arrangement satisfactory to both
parties under which such other party would obtain the claims, rights and
benefits and assume the corresponding liabilities and obligations thereunder
with respect to an additional pipeline.

          (j) If Duke or any Duke Retained Affiliate holds legal title to any of
the DEFS Easements for the benefit of DEFS or the DEFS Subsidiaries (or, in the
case of certain DEFS Multiple-User Easements, for the joint benefit of one or
more DEFS Subsidiaries, with respect to certain existing pipelines used in
connection with such DEFS Subsidiaries' business, and Duke or such Duke Retained
Affiliate, as the case may be, with respect to the remainder of such DEFS
Multiple-User Easement), or DEFS and the DEFS Subsidiaries hold legal title to
any of the DEFS Multiple-User Easements for the joint benefit of Duke or any
Duke Retained Affiliate, with respect to certain existing pipelines used in
connection with Duke's business, and DEFS or a DEFS Subsidiary, with respect to
the remainder of such DEFS Multiple-User Easement, then reciprocal covenants
corresponding to the covenants of Phillips set forth in Sections 6.8(a) through
6.8(h) hereof relating to the PGC Easements shall be deemed incorporated in this
Agreement and shall be applicable to and binding upon the parties hereto with
respect to the affected DEFS Easements.

          Section 6.9 ASSIGNMENT OF CONTRACTS, LEASES, PERMITS, ETC.
(a) Anything in this Agreement or the Governance Agreement to the contrary
notwithstanding, this Agreement and the Governance Agreement shall not
constitute an agreement to assign any contract, lease or Permit or any claim,
right or benefit if an attempted assignment thereof, without the consent of a
third party, would constitute a breach or other contravention thereof, be
ineffective with respect to any party thereto or in any way adversely affect the
rights of the Company, a DEFS Subsidiary or a PGC Subsidiary thereunder.

          (b) With respect to any contract, lease or Permit necessary to the
conduct of business of the DEFS Subsidiaries or the PGC Subsidiaries as
presently conducted (and any claim, right or benefit arising thereunder or
resulting therefrom) and not currently held by a DEFS Subsidiary or a PGC
Subsidiary, other than the matters addressed in Sections 6.8, 6.18 and 6.19
(including the PGC Easements) and 6.20, Duke, Phillips and the Company will use
their reasonable best efforts to obtain as expeditiously as possible the written
consent of the other parties to such contract, lease or Permit for the
assignment or, if required, novation, thereof to the Company or a DEFS
Subsidiary or a PGC Subsidiary, as applicable, or, alternatively, written
confirmation from such parties reasonably satisfactory in form and substance to
Duke and Phillips that such consent is not required. In furtherance of the
foregoing, except with regard to the matters addressed in Sections 6.8, 6.18,
6.19 and 6.20 as soon as practicable following the date hereof, Duke and
Phillips shall submit to the other party or parties thereto documentation
seeking the written waiver or approval of such other contracting party or
parties thereto to the transfer and assignment of all of Duke's or Phillips', as
applicable, claims, rights, benefits and liabilities thereunder to the Company
or a DEFS Subsidiary or a PGC Subsidiary, as applicable.

          (c) The failure by the Parties to obtain any required consent, waiver,
confirmation, novation or approval with respect to any contract, lease, Permit,
PGC Easement, DEFS Easement or FCC License shall not relieve either Party from
its obligation to consummate at the Closing the transactions contemplated by
this Agreement or the Governance Agreement or any other obligations hereunder or
thereunder unless such failures would in the aggregate have a Material Adverse
Effect on DEFS or the PGC Subsidiaries.

          (d) Except with regard to the matters addressed in Sections 6.8, 6.18,
6.19 and 6.20, if any consent, waiver, confirmation, novation or approval is not
obtained prior to the Closing with respect to any contract, lease or Permit
necessary to the conduct of the business of the DEFS Subsidiaries or the PGC
Subsidiaries as presently conducted, then Duke or Phillips, as applicable, shall
establish an agency type or other arrangement satisfactory to the other Party
and to the Company under which Duke or Phillips, as applicable, shall hold such
interest, lease or Permit for the DEFS Subsidiary or PGC Subsidiary, as
applicable, and the affected DEFS Subsidiary or PGC Subsidiary would obtain the
claims, rights and benefits and assume the corresponding liabilities and
obligations thereunder in accordance with this Agreement (including by means of
any subcontracting, sublicensing or subleasing arrangement) or under which Duke
or Phillips, as applicable, would enforce at the direction of and for the
benefit of the DEFS Subsidiary or PGC Subsidiary, as applicable, with the DEFS
Subsidiary or PGC Subsidiary, as applicable, assuming and agreeing to pay Duke's
or Phillips' obligations and expenses, any and all claims, rights and benefits
of Duke or Phillips against a third party thereto; PROVIDED that Duke's or
Phillips' obligation to maintain any such arrangement shall terminate upon the
earliest to occur of: (1) the expiration or termination of such contract, lease
or Permit

                                       -47-
<PAGE>

in accordance with its terms (without regard to any extensions,
automatic or otherwise); or (2) with regard to a Permit, such time as the
Company, the DEFS Subsidiary or the PGC Subsidiary, as the case may be, shall
obtain a Permit in reasonable substitution therefor, or have its application for
such substitute Permit denied. In any such arrangement, (i) Duke or Phillips, as
applicable, shall promptly pay to the DEFS Subsidiary or PGC Subsidiary, as
applicable, when received all moneys relating to the period after the Closing
Date received by it under any contract or any claim, right or benefit arising
thereunder not transferred pursuant to this Section 6.9 and (ii) the applicable
DEFS Subsidiary or PGC Subsidiary shall promptly pay, perform or discharge when
due any obligation or liability arising thereunder after the Closing Date.

          Section 6.10 CORPORATE NAMES. (a) The Company and Duke acknowledge
that, from and after the Closing Date, the Company and Duke shall have no rights
with respect to any names, marks, trade names, trademarks and logos
(collectively, "TRADEMARKS AND LOGOS") incorporating "Phillips" or "66" by
themselves or in combination with any other Trademark or Logo, including the
corporate design logos associated therewith, and that Phillips shall retain
absolute and exclusive proprietary rights thereto or goodwill represented
thereby or pertaining thereto. The Company agrees that promptly after the
Closing Date it shall amend and cause to be amended the certificate of
incorporation or other organizational documents of Phillips Natural Gas Company
(or its successor entity) to remove the "Phillips" name and that from and after
the Closing Date, the Company and Duke shall not, nor shall they permit any of
their respective Affiliates to, use any name, phrase or logo incorporating
"Phillips" or "66" or such corporate design logo or any confusingly similar
name, phrase, logo or corporate design logo in or on any of its literature,
sales materials or products or otherwise in connection with the sale of any
products or services; PROVIDED, HOWEVER, that the Company may continue to use
any signage, printed literature, sales materials, purchase orders and sales or
lease agreements, and sell any products, that are included in the inventories of
PGC on the Closing Date and that bear a name, phrase or logo incorporating
"Phillips" or "66" or such corporate design logo, until the supplies thereof
existing on the Closing Date have been exhausted, but in any event for not
longer than 180 days from the Closing Date.

          (b)   (i) Except as set forth in Section 6.10(b)(ii), the Company and
Phillips acknowledge that, from and after the Closing Date, the Company and
Phillips shall have no rights with respect to Trademarks and Logos incorporating
"Duke" by itself or in combination with any other Trademark or Logo, including
the corporate design logos associated therewith, and that Duke shall retain
absolute and exclusive proprietary rights thereto or goodwill represented
thereby or pertaining thereto.

            (ii) Duke shall grant the Company and the Corporation a royalty-free
license to the word "Duke", which shall be terminable at the option of Duke if
(A) Duke's ownership interest, both direct and indirect, in the Company or the
Corporation, as applicable, at any time, is less than or equal to 35% or (B)
Duke no longer controls, directly or indirectly, the management and policies of
the Company or the Corporation, as applicable. Such license shall include
appropriate restrictions with respect to the nature and quality of goods and
services in connection with which the Duke name or mark are used. The Company
agrees that if Duke provides notice to the Company that (1) its ownership
interest, both direct and indirect, in the Company, at any time, is less than or
equal to 35% or (2) it no longer controls, directly or



                                       -48-
<PAGE>

indirectly, the management and policies of the Company, and that Duke wishes to
terminate the Company's license to the Duke name, the Company shall amend its
limited liability company agreement or other organizational documents and cause
to be amended the certificates of incorporation or other organizational
documents of the Corporation and its Subsidiaries, as applicable, to remove the
"Duke" name and that thereafter the Company shall not, nor shall it permit the
Corporation or any of its Affiliates to, use any name, phrase or logo
incorporating "Duke" or such corporate design logo or any confusingly similar
name, phrase, logo or corporate design logo in or on any of its literature,
sales materials or products or otherwise in connection with the sale of any
products or services; PROVIDED, HOWEVER, that the Company or the Corporation, as
applicable, may continue to use any signage, printed literature, sales
materials, purchase orders and sales or lease agreements, and sell any products,
that are included in its inventories on such date and that bear a name, phrase
or logo incorporating "Duke" or such corporate design logo, until the supplies
thereof existing on such date have been exhausted, but in any event for not
longer than 180 days from the date of such notice.

          Section 6.11 D&O INDEMNIFICATION. The parties hereto agree that the
transactions contemplated by this Agreement and the Governance Agreement shall
not affect or diminish any duties and obligations of indemnification from Duke
or Phillips or their respective Affiliates (other than the DEFS Subsidiaries and
the PGC Subsidiaries) existing as of the Closing Date in favor of employees,
agents, directors or officers of the DEFS Subsidiaries or the PGC Subsidiaries,
respectively, arising by virtue of their respective certificates of
incorporation or by-laws or other organizational documents in the form in effect
at the date of this Agreement or arising by operation of law or arising by
virtue of any contract, resolution or other agreement or document existing at
the date of this Agreement, and such duties and obligations shall continue in
full force and effect and shall be honored by the Company for so long as they
would (but for the transactions contemplated by this Agreement and the
Governance Agreement) otherwise survive and continue in full force and effect.

          Section 6.12 ADDITIONAL AGREEMENTS. Simultaneously with the execution
of this Agreement, Duke, Phillips and the Company are entering into the
Governance Agreement. At or prior to the Closing, Duke, Phillips and the Company
shall enter into a transition services agreement (the "TRANSITION SERVICES
AGREEMENT"), providing for the provision of certain transitional services by
Duke and Phillips to be reasonably requested by the Company at fully-burdened
cost for a period of not more than one year after the Closing Date.

          Section 6.13 EXPENSES. Pre-Closing expenses and accruals of the DEFS
Subsidiaries arising out of the transactions contemplated by this Agreement and
the Governance Agreement and all other pre-Closing expenses of the DEFS
Subsidiaries shall be borne by Duke. Pre-Closing expenses and accruals of the
PGC Subsidiaries arising out of the transactions contemplated by this Agreement
and the Governance Agreement and all other pre-Closing expenses of the PGC
Subsidiaries shall be borne by Phillips.

          Section 6.14 INSURANCE. (a) Duke and the Company acknowledge that the
programs and policies of insurance maintained by Phillips to provide coverage in
favor of the PGC Subsidiaries shall be terminated effective 12:01 A.M. on the
day following the Closing Date. From and after the Closing Date, all risk of
loss with respect to properties and assets of the PGC Subsidiaries shall be
borne by the Company. With respect to events occurring prior to the

                                       -49-
<PAGE>

Closing Date, the PGC Subsidiaries shall be entitled to the benefits of
insurance from independent sources (not affiliated with Phillips) maintained by
or for the benefit of the PGC Subsidiaries with respect to properties and assets
of the PGC Subsidiaries; PROVIDED, HOWEVER, that notwithstanding anything to the
contrary contained in this Agreement or the Governance Agreement, from and after
the Closing Date, the PGC Subsidiaries shall not be entitled to any insurance
recovery from any Phillips-affiliated insurance company. Further, the Company
shall indemnify and hold harmless Phillips from any retroactive premiums imposed
by any insurer under programs or policies maintained by Phillips prior to
Closing as a result of any claims made after the Closing Date with respect to
the properties and assets of the PGC Subsidiaries regardless of the date of
loss.

          (b) Phillips and the Company acknowledge that the programs and
policies of insurance maintained by Duke to provide coverage in favor of the
DEFS Subsidiaries shall be terminated effective 12:01 A.M. on the day following
the Closing Date. From and after the Closing Date, except as agreed to by the
Company and Duke, all risk of loss with respect to properties and assets of the
DEFS Subsidiaries shall be borne by the Company. With respect to events
occurring prior to the Closing Date, the DEFS Subsidiaries shall be entitled to
the benefits of insurance from independent sources (not affiliated with Duke)
maintained by or for the benefit of the DEFS Subsidiaries with respect to
properties and assets of the DEFS Subsidiaries; provided, however, that
notwithstanding anything to the contrary contained in this Agreement or the
Governance Agreement, from and after the Closing Date, except as agreed to by
the Company and Duke, the DEFS Subsidiaries shall not be entitled to any
insurance recovery from any Duke-affiliated insurance company. Further, the
Company shall indemnify and hold harmless Duke from any retroactive premiums
imposed by any insurer under programs or policies maintained by Duke prior to
Closing as a result of any claims made after the Closing Date with respect to
the properties and assets of the DEFS Subsidiaries regardless of the date of
loss.

          Section 6.15 GUARANTIES. (a) In the event that after the Closing Date
Phillips or any Affiliate of Phillips (other than the PGC Subsidiaries) remains
liable for any guarantees (whether of payment or performance), letters of credit
or other undertakings it has delivered prior to the Closing Date to others for
the benefit of any PGC Subsidiary, the Company agrees to indemnify and hold
harmless Phillips or such Affiliate of Phillips from any cost, expense or loss
(including reasonable attorneys' fees) incurred by Phillips or such Affiliate of
Phillips arising directly or indirectly therefrom with respect to pre-Closing
periods except insofar as such cost, expense or loss constitutes or arises from
a matter with respect to which the Company or any of its Affiliates (including
the PGC Subsidiaries) is entitled to indemnification hereunder. Any such
guarantees, letters of credit or other undertakings (including performance
guarantees) are set forth in Schedule 6.15(a) of the Phillips Disclosure
Schedule. Any reasonable out-of-pocket expense incurred by Phillips with respect
to maintaining such support for periods after the Closing Date shall be
reimbursed to Phillips by the Company. The Company shall use its best efforts
(including an offer of a substitute guarantee, letter of credit or undertaking)
to cause or procure the release, within six months of the Closing Date, of all
liabilities or obligations of Phillips or any Affiliate of Phillips (other than
the PGC Subsidiaries) with respect to such guaranties, letters of credit or
other undertakings from any of the liabilities or obligations of any PGC
Subsidiary for post-Closing periods.

                                       -50-
<PAGE>

          (b) In the event that after the Closing Date Duke or any Affiliate of
Duke (other than the Company and the DEFS Subsidiaries) remains liable for any
guarantees (whether of payment or performance), letters of credit or other
undertakings it has delivered prior to the Closing Date to others for the
benefit of any DEFS Subsidiary, the Company agrees to indemnify and hold
harmless Duke or such Affiliate of Duke from any cost, expense or loss
(including reasonable attorneys' fees) incurred by Duke or such Affiliate of
Duke arising directly or indirectly therefrom with respect to pre-Closing
periods except insofar as such cost, expense or loss constitutes or arises from
a matter with respect to which the Company or any of its Affiliates (including
the DEFS Subsidiaries) is entitled to indemnification hereunder. Any such
guarantees, letters of credit or other undertakings (including performance
guarantees) are set forth in Schedule 6.15(b) of the Duke Disclosure Schedule.
Any reasonable out-of-pocket expense incurred by Duke with respect to
maintaining such support for periods after the Closing Date shall be reimbursed
to Duke by the Company. The Company shall use its best efforts (including an
offer of a substitute guarantee, letter of credit or undertaking) to cause or
procure the release, within six months of the Closing Date, of all liabilities
or obligations of Duke or any Affiliate of Duke (other than the Company and the
DEFS Subsidiaries) with respect to such guaranties, letters of credit or other
undertakings from any of the liabilities or obligations of any DEFS Subsidiary
for post-Closing periods.

          Section 6.16 ACTIONS BY AFFILIATES OF PHILLIPS AND DUKE. Each of
Phillips and Duke shall ensure that each of their respective Affiliates (other
than, following the Closing, the Company and the Corporation) takes all actions
necessary to be taken by such Affiliate in order to fulfill the obligations of
Phillips or Duke, as the case may be, under this Agreement and the Governance
Agreement.

          Section 6.17 FINANCING. (a) Prior to the Closing, each of Duke and
Phillips shall use its reasonable best efforts and cooperate with each other to
cause the Company to secure bank credit facilities of at least the sum of (i)
$2,400,000,000, (ii) an amount equal to the aggregate purchase prices of any of
the acquisitions set forth in Schedule 6.4(e) of the Phillips Disclosure
Schedule and in Schedule 6.5(e) of the Duke Disclosure Schedule with respect to
which acquisition documents have been executed or the closing has been
consummated, (iii) an amount equal to the aggregate purchase prices of any
acquisitions approved by Duke or Phillips, as applicable, pursuant to Section
6.4 or 6.5 prior to the Closing Date with respect to which acquisition documents
have been executed or the closing has been consummated, and (iv) an amount
reasonably necessary for working capital purposes for the Company, on reasonably
available commercial terms mutually agreeable to the parties hereto
(collectively, the "FINANCING").

          Section 6.18 PGC REAL PROPERTY. (a) FEE PROPERTIES. (i) Record title
to any PGC-Owned Fee Property that is not owned of record by any of the PGC
Subsidiaries as of the date hereof shall be conveyed to the appropriate PGC
Subsidiary on or prior to the Closing Date by general warranty deed in form
customary for the state in which such PGC-Owned Fee Property is located.
Phillips shall cause each such general warranty deed to be prepared, executed
and filed of record in the appropriate land title recording office, and shall
pay all recording fees, deed stamp taxes and other costs incurred in connection
with such recordation.

                                       -51-
<PAGE>

               (ii) If any PGC-Owned Fee Property is currently being used
simultaneously by Phillips (or a Phillips Retained Affiliate) and by a PGC
Subsidiary in their respective business operations, then Phillips and Duke, both
acting reasonably and in good faith, shall jointly prepare and agree upon a
mutually acceptable arrangement whereby Phillips (or such Phillips Retained
Affiliate, as the case may be) will be permitted to continue subsequent to the
Closing to use and occupy such PGC-Owned Fee Property for substantially the same
purpose, in substantially the same manner and to substantially the same extent
as prior to the Closing. Any such shared-use arrangement with respect to a
PGC-Owned Fee Property (A) shall be finalized not later than the date on which
fee title to such PGC-Owned Fee Property is conveyed of record to the applicable
PGC Subsidiary, (B) shall be structured so as to minimize the interference of
any use of such PGC-Owned Fee Property by either party to such arrangement with
any use of such PGC-Owned Fee Property by the other party, and (C) shall provide
for reasonable rights of ingress and egress to and from such PGC-Owned Fee
Property where necessary. It is anticipated that any such shared-use
arrangements with respect to PGC-Owned Fee Properties will in most cases consist
of perpetual easements or licenses granted by a PGC Subsidiary to Phillips or a
Phillips Retained Affiliate. However, in the case of certain PGC-Owned Fee
Properties (identified in Schedule 4.11(a) of the Phillips Disclosure Schedule)
it may be necessary or desirable for a PGC Subsidiary to reconvey to Phillips or
a Phillips Retained Affiliate fee title to the portion of such PGC-Owned Fee
Property that is being used by Phillips or such Phillips Retained Affiliate, as
the case may be. In any such case, Phillips shall pay, or cause the applicable
Phillips Retained Affiliate to pay, all recording fees, deed stamp taxes and
other costs incurred in connection with such reconveyance.

          (b) REALTY LEASES. (i) Not later than the Closing Date, Phillips shall
prepare and deliver to the Company an updated schedule of PGC Leases, which
updated schedule shall indicate, with respect to each Non-Government PGC Lease
that is not held of record by any of the PGC Subsidiaries as of the date hereof,
whether assignment of such PGC Lease requires the consent of the lessor
thereunder (those Non-Government PGC Leases which do not require lessor consent
being sometimes referred to in this Agreement, collectively, as "ASSIGNABLE PGC
LEASES"). The information set forth on the updated PGC Lease schedule shall be
for the information and benefit of the Company only, and shall not confer upon
any lessor or other third party any consent or approval right that is not
expressly provided for in the applicable PGC Lease.

               (ii) Each Assignable PGC Lease shall be assigned to the
appropriate PGC Subsidiary on or prior to the Closing Date by special warranty
assignment in recordable form customary for the state in which the property
demised by such Assignable PGC Lease is located. Phillips shall cause each such
special warranty assignment to be prepared, executed and filed of record in the
appropriate land title recording office, and shall pay all recording fees, deed
stamp taxes and other costs incurred in connection with such recordation.

               (iii) From and after the Closing, with respect to any PGC Lease
the leasehold estate under which continues to be held of record by Phillips or a
Phillips Retained Affiliate ("RETAINED PGC LEASE"), Phillips shall continue to
use commercially reasonable efforts to obtain the consent of the lessor under
such Retained PGC Lease to the assignment thereof to the appropriate PGC
Subsidiary. Phillips shall pay and be responsible for and shall indemnify,
defend and hold harmless the Company from and against any amounts reasonably
required to be

                                       -52-
<PAGE>

paid in order to obtain the consent of the lessor under any Retained PGC Lease
to the assignment thereof. If and when the requisite consent to assignment shall
be obtained with respect to any Retained PGC Lease, such Retained PGC Lease
shall be assigned to the appropriate PGC Subsidiary by special warranty
assignment in recordable form customary for the state in which the property
demised by such Retained PGC Lease is located. Phillips shall cause each such
special warranty assignment to be prepared, executed and filed of record in the
appropriate land title recording office, and shall pay all recording fees, deed
stamp taxes and other costs incurred in connection with such recordation.

               (iv) At all times from and after the Closing while the leasehold
estate under any Retained PGC Lease shall continue to be held of record by
Phillips or any Phillips Retained Affiliate, Phillips or such Phillips Retained
Affiliate, as the case may be, shall hold such Retained PGC Lease and exercise
and enforce its rights thereunder for the use and benefit of, and in such manner
as may be reasonably directed by, the appropriate PGC Subsidiary. In connection
with any Retained PGC Lease, Duke and Phillips agree as follows:

                    (A)   Phillips shall indemnify, defend and hold harmless the
          Company and its Subsidiaries from and against any and all Damages,
          excluding consequential and punitive Damages, suffered or incurred by
          the Company or such Subsidiaries after Closing as a result of the
          failure of Phillips to have assigned such Retained PGC Lease to the
          PGC Subsidiaries by the Closing Date (all necessary third party
          consents having been obtained); provided, however, that such indemnity
          shall not extend to any Damages resulting from or attributable to the
          failure or inability of the Company to obtain financing for the
          transactions contemplated by this Agreement.

                    (B)   The Company shall indemnify, defend and hold harmless
          Phillips and the Phillips Retained Affiliates from and against any and
          all Damages, excluding consequential and punitive Damages, suffered or
          incurred by such entities after Closing in respect of such Retained
          PGC Lease to the extent such Damages consist of Subject Lease
          Liabilities that the Company or its Subsidiaries would have been
          responsible for, had such Retained PGC Lease been assigned to the PGC
          Subsidiaries by the Closing Date (all necessary third party consents
          having been obtained).

As used in this Section 6.18, the term "SUBJECT LEASE LIABILITIES" shall mean,
with respect to a Phillips Retained Easement, any and all payment obligations to
third parties, including lease rentals, renewal fees, ad valorem and other
taxes, arising and relating to the period from and after Closing in respect of
such Retained PGC Lease.

               (v) At any time following the Closing Date, the Company may
notify Phillips in writing that the Company, because of significant business
needs or opportunities, as to which time is of the essence (as determined in
good faith by the General Counsel of the Company), requires Phillips to complete
promptly the transfer of record legal title to the PGC Subsidiaries of specified
Retained PGC Leases identified by the Company. If Phillips fails to complete
such transfer within 30 days following such notice, the Company shall have the
right, but not the obligation, to take such reasonable actions as it deems
necessary or appropriate to remedy such failure ("LEASE CURATIVE ACTIONS"). The
Lease Curative Actions may include (i) the preparation of an assignment in the
form required under Section 6.18(b)(ii) for the applicable

                                       -53-
<PAGE>

Retained PGC Lease, (ii) the payment of any amounts required to be paid to a
third party for the granting of any consents required for such assignment, (iii)
obtaining a new lease from the landowner to replace the Retained PGC Lease, (iv)
provided that none of the other Lease Curative Actions are reasonably likely, in
the good faith opinion of the Company, to remedy such failure, obtaining a lease
for a new site for the affected facilities and moving them to the new site, and
(v) such other actions as are reasonable under the circumstances. Phillips shall
give the Company and its representatives reasonable access to any records in the
possession of Phillips or its Subsidiaries necessary for the Company to prepare
such assignments and property descriptions therefor, provided such access does
not unreasonably interfere with any significant business need or opportunity as
to which time is of the essence. Within twenty (20) days following the request,
Phillips shall reimburse the Company for all commercially reasonable costs
incurred by the Company for the Lease Curative Actions (including reimbursement
for Company personnel time at their normal hourly rates). The provisions of this
Section 6.18(b)(v) shall not limit the indemnification obligations of Phillips
under Section 6.18(b)(iv).

               (vi) If any PGC Leased Property is currently being used
simultaneously by Phillips (or a Phillips Retained Affiliate) and by a PGC
Subsidiary in their respective business operations, then Phillips and Duke, both
acting reasonably and in good faith, shall jointly prepare and agree upon a
mutually acceptable arrangement whereby Phillips (or such Phillips Retained
Affiliate, as the case may be) will be permitted to continue subsequent to the
Closing to use and occupy such PGC Leased Property for substantially the same
purpose, in the substantially the same manner and to substantially the same
extent as prior to the Closing. Any such shared-use arrangement with respect to
a PGC Leased Property (A) shall be finalized not later than the date on which
the related PGC Lease is assigned of record to the applicable PGC Subsidiary,
(B) shall be structured so as to minimize the interference of any use of such
PGC Leased Property by either party to such arrangement with any use of such PGC
Leased Property by the other party, (C) shall provide for reasonable rights of
ingress and egress to and from such PGC Leased Property where necessary, and (D)
shall provide for Phillips to retain liability for all pre-Closing environmental
conditions as to the portion of the leased property used by Phillips or a
Phillips Retained Affiliate.

               (vii) If all or part of any pipeline owned or used by the PGS
Subsidiaries is constructed upon any PGC Lease (a "PGC PIPELINE LEASE"), then
(A) all of the provisions of Section 6.8 shall apply (in lieu of the provisions
of this Section 6.18(b)) to such PGC Pipeline Lease to the same extent as a PGC
Easement, (B) if such PGC Pipeline Lease relates to a pipeline identified in
Exhibit 6.8(e) annexed to this Agreement, then Phillips shall cause record legal
title to such PGC Pipeline Lease to be transferred to the PGC Subsidiaries not
later than the Easement Assignment Deadline for the PGC Trunkline Easements as
set forth in Section 6.8(e), and (C) Phillips shall cause record legal title to
any PGC Pipeline Lease not referenced in the preceding clause (B) to be
transferred to the PGC Subsidiaries not later than the Easement Assignment
Deadline for the PGC Gathering Easements as set forth in Section 6.8(e).

          Section 6.19 DEFS REAL PROPERTY. In the event that Duke or any Duke
Retained Affiliate holds legal title to any of the DEFS-Owned Fee Properties or
the leasehold estate under any of the DEFS Leases for the benefit of the DEFS
Subsidiaries, then reciprocal covenants corresponding to the covenants set forth
in Section 6.18 hereof relating to the PGC-Owned Fee Properties or the PGC
Leases, as the case may be, shall be deemed incorporated in this

                                       -54-
<PAGE>

Agreement and shall be applicable to and binding upon the parties hereto with
respect to the affected DEFS-Owned Fee Property or the leasehold estate under
the affected DEFS Lease, as the case may be.

          Section 6.20 FCC LICENSES; RADIO TOWERS. (a) Prior to the Closing
Date, or as soon thereafter as practicable, Phillips shall use commercially
reasonable efforts to assign, or cause to be assigned, to the PGC Subsidiaries
all of the FCC Licenses used solely by them but held of record by Phillips or a
Phillips Retained Affiliate as of the date hereof, including those identified on
Schedule 6.20(a) of the Phillips Disclosure Schedule. Phillips shall cause each
such assignment to be filed with the Federal Communications Commission, shall
use commercially reasonable efforts to obtain any approvals and consents from
such Commission necessary for such transfer and shall pay all fees and other
costs incurred in connection with such assignment.

          (b) This clause (b) applies to any FCC License identified in Schedule
6.20(a) of the Phillips Disclosure Schedule that is currently being used
simultaneously by Phillips or a Phillips Retained Affiliate and by a PGC
Subsidiary in their respective business operations ("SHARED FCC LICENSE"). Prior
to the Closing, Phillips shall use commercially reasonable efforts to obtain two
FCC Licenses in replacement of the Shared FCC License, one in the name of and
for the benefit of Phillips or such Phillips Retained Affiliate and the second
in the name of and for the benefit of the PGC Subsidiary. Phillips shall pay, or
cause the applicable Phillips Retained Affiliate to pay, all fees and other
costs incurred in connection with the issuance of such replacement FCC Licenses.
In the event that Phillips is unable to obtain two replacement licenses,
Phillips will transfer the Shared FCC License to the PGC Subsidiary subject to a
mutually acceptable arrangement whereby Phillips or such Phillips Retained
Affiliate, as the case may be, shall be permitted to continue to use such FCC
License subsequent to the Closing for substantially the same purpose, in
substantially the same manner and to substantially the same extent as prior to
the Closing. Any such shared-use arrangement with respect to the Shared FCC
License shall be finalized not later than the date on which the Shared FCC
License is transferred. Phillips shall pay, or shall cause the applicable
Phillips Retained Affiliate to pay, all fees and other costs incurred in
connection with such assignment.

          (c) If Phillips or a Phillips Retained Affiliate, as of the date of
this Agreement, owns the radio tower corresponding to any FCC License identified
in Schedule 6.20(a) of the Phillips Disclosure Schedule, then Phillips and Duke,
both acting reasonably and in good faith, shall jointly prepare and agree upon a
mutually acceptable arrangement whereby Phillips or such Phillips Retained
Affiliate, as the case may be, shall be permitted to continue to use such radio
tower subsequent to the Closing for substantially the same purpose, in
substantially the same manner and to substantially the same extent as prior to
the Closing. Phillips shall use commercially reasonable efforts to obtain, prior
to Closing, consent of third party tower lessors for the assignment to the PGC
Subsidiary of all tower leases corresponding to the FCC Licenses required to be
transferred herein. In those instances where the third party lessor does not
consent to such transfer, Phillips and Duke shall prepare and agree upon a
shared use agreement with respect to the radio tower as described below. Any
such shared-use arrangement with respect to a radio tower (i) shall be finalized
not later than the date on which title to such radio tower is conveyed of record
to the affected PGC Subsidiary, (ii) shall be structured so as to minimize the
interference of any use of such radio tower by either party to such arrangement
with any use of such radio tower by the other party, and (iii) shall provide for

                                       -55-
<PAGE>


reasonable rights of ingress and egress to and from such radio tower where
necessary. It is anticipated that any such shared-use arrangements with respect
to radio towers will in most cases consist of (A) the transfer by Phillips or
the Phillips Retained Affiliate to the PGC Subsidiaries of record legal title to
such radio tower and the fee property on which such tower is located and (B) the
grant by the affected PGC Subsidiary of a perpetual easement or license to
Phillips or a Phillips Retained Affiliate. Phillips shall cause a general
warranty deed for each such transfer to be prepared, executed and filed of
record in the appropriate land title recording office, and shall pay all
recording fees, deed stamp taxes and other costs incurred in connection with
such recordation.

          (d) Prior to the Closing Date, or as soon thereafter as practicable,
Duke shall use commercially reasonable efforts to cause to be assigned to the
DEFS Subsidiaries all of the FCC Licenses used solely by them but held of record
by third parties as of the date hereof, including those identified on Schedule
6.20(d) of the Duke Disclosure Schedule. Duke shall use its commercially
reasonable efforts to (i) cause each such assignment to be filed with the
Federal Communications Commission, and (ii) obtain any approvals and consents
from such Commission necessary for such transfer, and Duke shall pay all fees
and other costs incurred in connection with such assignment (other than such
fees and costs paid by such third parties).

                                  ARTICLE VIII

                                   TERMINATION

          Section 8.1  TERMINATION.  This Agreement may be terminated at any
time prior to the Closing by:

          (a) The mutual written consent of Duke and Phillips;

          (b) Either Duke or Phillips if the Closing has not occurred by the
close of business on September 30, 2000, PROVIDED that the failure to consummate
the transactions contemplated by this Agreement did not result from the failure
by the party seeking termination of this Agreement to fulfill any material
undertaking or commitment provided for herein that is required to be fulfilled
prior to the Closing;

          (c) Either Duke or Phillips if the other Party shall have breached or
failed to perform in any material respect any of its respective representations,
warranties, covenants or other agreements contained in this Agreement, which
breach or failure to perform (i) would give rise to the failure of a condition
set forth in Section 7.1(a) or 7.2(a), as applicable, and (ii) cannot be or has
not been cured within 30 days after the giving of written notice to Duke or
Phillips, as applicable; or

          (d) Either Duke or Phillips in the event that any order, law, statute,
ordinance, rule, regulation or decree becomes effective (and final and
nonappealable) permanently restraining, enjoining or otherwise prohibiting or
making illegal or otherwise prohibiting the consummation of a material portion
of the transactions contemplated by this Agreement or the Governance Agreement,
upon notification of the non-terminating party by the terminating party.

          Section 8.2 PROCEDURE AND EFFECT OF TERMINATION. In the event of
termination of this Agreement by either or both of Duke and Phillips pursuant to
Section 8.1, written notice thereof shall forthwith be given by the terminating
party to the other parties hereto, and this Agreement shall thereupon terminate
and become void and have no effect, and the transactions contemplated by this
Agreement shall be abandoned without further action by the parties hereto,
except that the provisions of Section 6.1(b) shall survive the termination of
this Agreement; PROVIDED, HOWEVER, that such termination shall not relieve any
party hereto of any liability for any willful breach of this Agreement. If this
Agreement is terminated as provided herein, the Governance Agreement shall
simultaneously be terminated, and all filings, applications and other
submissions made pursuant hereto shall, to the extent practicable, be withdrawn
from the

                                       -58-

agency or other persons to which they were made by the party making

                                   ARTICLE IX

                            SURVIVAL; INDEMNIFICATION

          Section 9.1 INDEMNIFICATION BY COMPANY. Subject to the provisions of
this Article IX, the Company shall indemnify and hold harmless each of Phillips
and its Affiliates (other than the Company and its Subsidiaries) (each a
"PHILLIPS INDEMNIFIED PERSON") and Duke and its Affiliates (other than the
Company and its Subsidiaries) (each a "DUKE INDEMNIFIED PERSON") from and
against any and all Damages incurred by such Phillips Indemnified Person or Duke
Indemnified Person in connection with (i) any failure by the Company to perform
any covenant or other agreement hereunder, (ii) all Liabilities of a Phillips
Indemnified Person or a Duke Indemnified Person arising under the Comprehensive
Environmental Response, Compensation, and Liability Act of 1980, as amended,
solely by virtue of its status as an owner of any of the PGC Subsidiaries or the
DEFS Subsidiaries prior to the Closing Date, except in each case for matters
indemnified under Sections 9.2(a) and 9.2(b), and (iii) all Liabilities made the
responsibility of the Company and/or its Subsidiaries pursuant to Annex A.

          Section 9.2 INDEMNIFICATION BY DUKE AND PHILLIPS. (a) Subject to the
provisions of this Article IX, Duke shall indemnify and hold harmless Phillips
and its Affiliates and the Company and its Affiliates (excluding Duke and, prior
to the IPO, DEFS Holding, but including the DEFS Subsidiaries following the
Closing) from and against any and all Damages incurred by Phillips and its
Affiliates or the Company and its Affiliates (excluding Duke and, prior to the
IPO, DEFS Holding but including the DEFS Subsidiaries following the Closing) in
connection with (i) a breach of any representation or warranty made by Duke
hereunder or in any schedule, exhibit or other document attached to or delivered
pursuant to this Agreement, (ii) any failure by Duke to perform any covenant or
agreement hereunder, (iii) all Liabilities included in Duke Excluded Assets and
Liabilities and (iv) all Liabilities made the responsibility of Duke and/or its
Subsidiaries (other than the Company and its Subsidiaries) pursuant to Annex A.

          (b) Subject to the provisions of this Article IX, Phillips shall
indemnify and hold harmless Duke and its Affiliates and the Company and its
Affiliates (excluding Phillips and, prior to the IPO, PGC and PGC Member Parent
but including the PGC Subsidiaries following the Closing) from and against any
and all Damages incurred by Duke and its Affiliates or the Company or its
Affiliates (excluding Phillips, prior to the IPO, and PGC and PGC Member Parent,
but including the PGC Subsidiaries following the Closing) in connection with (i)
a breach of any representation or warranty made by Phillips hereunder or in any
schedule, exhibit or other document attached to or delivered pursuant to this
Agreement, (ii) any failure by Phillips to perform any covenant or agreement
hereunder, (iii) all Liabilities included in Phillips Excluded Assets and
Liabilities and (iv) all Liabilities made the responsibility of Phillips and/or
its Subsidiaries pursuant to Annex A.

          (c) Matters relating to indemnification for Taxes shall not be
governed by this Article IX (other than this Section 9.2(c)), except to the
extent otherwise provided in Annex B.

                                       -59-
<PAGE>

The parties hereto agree that the indemnification provisions in Article XI shall
be the exclusive remedy of the parties with respect to breaches of the
representations and warranties in Sections 6.1 and 6.2 of Annex B, except for
actions grounded in fraud, with respect to which the remedies and limitations
set forth in this Agreement shall not apply or in any manner limit the scope or
availability of any other remedy at law or in equity.

          Section 9.3 INDEMNIFICATION PROCEDURE. All claims by any Indemnified
Party under Article VI or this Article IX shall be asserted and resolved as
follows:

          (a) In the event that (i) any claim, demand or proceeding is asserted
or instituted in writing by any Person other than the parties to this Agreement
or their Affiliates which could give rise to Damages for which an Indemnifying
Party could be liable to an Indemnified Party under this Agreement (such claim,
demand or proceeding, a "THIRD PARTY CLAIM") or (ii) any Indemnified Party shall
have a claim to be indemnified by any Indemnifying Party under this Agreement
which does not involve a Third Party Claim (such claim, a "DIRECT CLAIM"), the
Indemnified Party shall promptly send to the Indemnifying Party a written notice
specifying the nature of such claim, together with information reasonably
available to the Indemnified Party with respect to such claim (a "CLAIM
NOTICE"), PROVIDED that, subject to the last sentence of Section 9.4, a delay in
notifying the Indemnifying Party shall not relieve the Indemnifying Party of its
obligations under this Agreement except to the extent that such failure shall
have caused actual prejudice to the Indemnifying Party. In the case where the
Company is the Indemnified Party, either Duke or Phillips may assert an
indemnity claim on behalf of the Company and each shall be considered an
Indemnified Party for purposes of this Section 9.3 in connection with any Third
Party Claim or Direct Claim for which the other is the Indemnifying Party.

          (b) In the event of a Third Party Claim, the Indemnifying Party shall
have 30 days after receipt of the Claim Notice relating to such Third Party
Claim to elect to undertake, conduct and control, through counsel of its own
choosing (PROVIDED that such counsel is reasonably acceptable to the Indemnified
Party) and at its own expense, the settlement or defense of such Third Party
Claim (in which case the Indemnifying Party shall not thereafter be responsible
for the fees and expenses of any separate counsel retained by any Indemnified
Party except as set forth below). If the Indemnifying Party elects to undertake
such defense, it shall promptly assume and hold such Indemnified Party harmless
from and against the full amount of any Damages resulting from such Third Party
Claim to the extent provided herein. Notwithstanding an Indemnifying Party's
election to undertake, conduct and control such Third Party Claim, the
Indemnified Party shall have the right to employ separate counsel, and the
Indemnifying Party shall bear the reasonable fees, costs and expenses of such
separate counsel, if the use of the counsel selected by the Indemnifying Party
to represent the Indemnified Party would present such counsel with a conflict of
interest. If the Indemnifying Party elects to undertake such defense, (i) the
Indemnified Party agrees to cooperate with the Indemnifying Party and its
counsel in contesting such Third Party Claim, and, if appropriate and related to
such Third Party Claim, the parties will reasonably cooperate with each other in
connection with making any counterclaim against the person asserting the Third
Party Claim, or any cross-complaint against any Person, (ii) such Third Party
Claim may not be settled or compromised by the Indemnified Party without the
prior written consent of the Indemnifying Party; PROVIDED that in the event any
Indemnified Party settles or compromises or consents to the entry of any

                                       -60-
<PAGE>

judgment with respect to any Third Party Claim without the prior written consent
of the Indemnifying Party, such Indemnified Party shall be deemed to have waived
all rights against the Indemnifying Party for indemnification under this Article
IX, and (iii) the Indemnifying Party shall not, except with the consent of the
Indemnified Party, enter into any settlement that does not include as an
unconditional term thereof the giving by the third party asserting such claim to
all Indemnified Parties of (A) unconditional release from all liability with
respect to such Third Party Claim or (B) consent to entry of any judgment. If
the Indemnifying Party does not notify the Indemnified Party of its election to
undertake the defense of such Third Party Claim within 30 days after receipt of
the Claim Notice relating to such Third Party Claim, the Indemnified Party shall
have the right to contest, settle, compromise or consent to the entry of any
judgment with respect to such Third Party Claim and in doing so shall not
thereby waive any right to indemnity therefor pursuant to this Article IX,
PROVIDED that at any time thereafter the Indemnifying Party may assume the
defense of such Third Party Claim.

          (c) In the event of a Direct Claim, the Indemnifying Party shall
notify the Indemnified Party within 30 days of receipt of a Claim Notice whether
or not the Indemnifying Party disputes such claim.

          (d) From and after the delivery of a Claim Notice under this
Agreement, at the reasonable request of the Indemnifying Party the Indemnified
Party shall grant the Indemnifying Party and its representatives all reasonable
access to the books, records and properties of such Indemnified Party to the
extent reasonably related to the matters to which the Claim Notice relates. All
such access shall be granted during normal business hours and shall be granted
under conditions which will not unreasonably interfere with the business and
operations of such Indemnified Party. The Indemnifying Party will not, and shall
cause its representatives not to, use (except in connection with such Claim
Notice) or disclose to any third Person other than the Indemnifying Party's
representatives (except as may be required by applicable law) any information
obtained pursuant to this Section 9.3, which is designated as confidential by
the Indemnified Party.

          Section 9.4 SURVIVAL. The representations and warranties of the
parties contained in this Agreement shall survive the Closing and remain
enforceable for 18 months from the Closing Date; PROVIDED that (i) the
representations and warranties set forth in Section 4.12 and 5.12
(Environmental) shall survive the Closing and remain enforceable for 36 months
from the Closing Date, (ii) the representations and warranties set forth in
Sections 4.1, 4.2, 4.3, 4.6, 5.1, 5.2, 5.3 and 5.6 shall survive the Closing and
remain enforceable without time limit and (iii) the representations and
warranties set forth in Annex B shall survive to the extent provided in Annex B.
No claim for indemnity under this Article IX for any breach of a representation
or warranty may be brought unless the appropriate Claim Notice shall have been
delivered to the Indemnifying Party prior to expiration of the applicable
survival period. Notwithstanding the foregoing, any covenants or agreements
contained in this Agreement (including any covenants or agreements contained in
any representation or warranty) shall survive the Closing and remain enforceable
without time limit.

          Section 9.5 INDEMNIFICATION LIMITATION. (a) Each Indemnified Party
under this Article IX shall use its reasonable efforts to mitigate Damages for
which it seeks indemnification hereunder and shall assign to the Indemnifying
Party all of such Indemnified Party's claims for

                                       -61-
<PAGE>

recovery against third parties as to Damages, whether by insurance coverage,
contribution claims, subrogation or otherwise.

          (b) Except as otherwise provided herein, each of Duke's and Phillips'
obligation to indemnify the other Party and its Affiliates and the Company and
its Affiliates as provided in Section 9.2 shall not become effective until the
aggregate of all Damages sustained by the other Party and its Affiliates and the
Company and its Affiliates as described in Section 9.2 shall have exceeded the
Basket. If the aggregate amount of Damages sustained by the other Party and its
Affiliates and the Company and its Affiliates as described in Section 9.2
exceeds the applicable Basket then the other Party and its Affiliates and the
Company and its Affiliates shall be entitled to assert claims under this Article
IX for indemnification for the amount of such Damages in excess of the
applicable Basket only; PROVIDED that each of Duke's and Phillips' obligation
under this Article IX shall not exceed the applicable Cap in the aggregate, and
PROVIDED, FURTHER, that none of Duke, Phillips or the Company or their
respective Affiliates shall be entitled to assert claims for indemnification
under this Article IX unless the aggregate amount of Damages claimed in any
individual Claim Notice exceeds $500,000 in the aggregate.

          (c) Notwithstanding the foregoing, the indemnification provision set
forth in Section 9.2(a)(ii), Section 9.2(a)(iii), Section 9.2(a)(iv), Section
9.2(b)(ii), Section 9.2(b)(iii) and Section 9.2(b)(iv) shall not be subject
to the Basket or Cap.

          (d) The parties hereto agree that the indemnification provisions in
Articles VI and IX shall be the exclusive remedy of the parties with respect to
breaches of the representations and warranties in Articles IV and V, except for
actions grounded in fraud, with respect to which the remedies and limitations
set forth in this Agreement shall not apply or in any manner limit the scope or
availability of any other remedy at law or in equity.

          Section 9.6 MATERIALITY QUALIFIERS. For purposes of determining
Damages and rights to indemnification under this Article IX, the representations
and warranties set forth in Articles IV and V shall be read without giving
effect to any Materiality Requirement set forth therein; provided, that
representations and warranties qualified by "Material Adverse Effect" shall be
deemed to be true to the extent the breach thereof is reasonably attributable to
the general state of the industries in which such Party and its Subsidiaries
operate (including natural gas and petroleum price levels), to general economic
conditions in the United States (including prevailing interest rate and stock
market levels) or to the transactions contemplated by this Agreement or the
other Transaction Agreements. As used in this Agreement, a "MATERIALITY
REQUIREMENT" shall mean any requirement in a representation or warranty that a
condition, event or state of fact be "material," correct or true in "all
material respects," have a "Material Adverse Effect," or be or not be
"reasonably expected to have a Material Adverse Effect" (or other words or
phrases of similar effect or impact) in order for such condition, event or state
of facts to cause such representation or warranty to be inaccurate.

principles thereof.

          (b) Each party 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 or the Governance
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
party hereto 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 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,

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, 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 this Agreement and the Governance Agreement.

          (d) Each party hereto waives, to the fullest extent permitted by
applicable law, any right it may have to a trial by jury in respect of any
action, suit or proceeding arising out of or relating to this Agreement or the
Governance Agreement. Each party hereto certifies that it

                                       -63-

has been induced to enter into this Agreement and the Governance Agreement by,

Effective as of the Closing Date, the Company shall assume all obligations and

the Company in its sole discretion.

          Section 3.2 INCENTIVE COMPENSATION. The Company shall determine the
amounts of the annual bonuses (the "BONUSES") earned by Continued Employees for
the year in which the Closing Date occurs under its bonus plans, and Phillips
(in the case of Transferred PGC Employees) and Duke (in the case of Retained
DEFS Employees) shall reimburse the Company for a pro-rata portion of the
Bonuses, based upon the number of full calendar months in such year before the
Closing Date. Such reimbursement shall include the employer's share of any
employment taxes relating to such pro-rata Bonuses for the period before the
Closing Date and required to be paid by the Company or any of its Subsidiaries.

                                   ARTICLE IV

                                EMPLOYEE BENEFITS

          Section 4.1 EMPLOYEE BENEFITS GENERALLY. (a) Effective as of the
Closing Date, except as provided in Section 4.2(b), the Continued Employees
shall cease to be active participants in the Parent Plans. Effective as of the
Closing Date, neither the Company nor any of its Subsidiaries shall be a
participating employer in any Parent Plan. Phillips and Duke shall remain solely
responsible for all liabilities with respect to the Phillips Plans and the Duke
Plans, respectively, and the Company and its Subsidiaries shall not assume any
Parent Plan and shall have no obligations and shall assume no liabilities with

which shall be designed by the

                                       -5-
<PAGE>

Company in its sole discretion. Phillips and Duke shall provide the Company and
its Subsidiaries with all necessary transition assistance to enable them to
develop and implement their compensation and benefit plans and programs.

          (c) For purposes of eligibility to participate and vesting under all
compensation and benefit plans applicable to Continued Employees on or after the
Closing Date, the Company and its Subsidiaries shall give Continued Employees
credit for all applicable service with Duke and its Subsidiaries (including the
Company, DEFS and their respective Subsidiaries), or Phillips and its
Subsidiaries, as applicable, before the Closing Date. For these purposes, the
applicable service for a Transferred PGC Employee shall be determined by the
elapsed time since his or her Service Award Entry Date as recorded in the
personnel records of Phillips.

          Section 4.2 SEVERANCE BENEFITS. (a) Phillips and its Subsidiaries
shall be solely responsible for all Severance Costs, if any, with respect to any

Subsidiaries shall be solely responsible for all Severance Costs, if any, with
respect to any DEFS Employee who does not become a Retained DEFS Employee.

          (b) Without limiting the generality of the foregoing and except as
provided in this Section 4.2(b), Duke and its Subsidiaries shall remain solely
responsible for all Liabilities under the Change in Control Severance Plan. Each
Retained DEFS Employee who was covered by the Change in Control Severance Plan
immediately before the Closing Date shall continue to be covered by such plan on
and after the Closing Date in accordance with the terms and conditions of such
plan. If any Retained DEFS Employee who is covered by the Change in Control
Severance Plan terminates employment with the Company and its Subsidiaries on or
after the Closing Date under circumstances entitling him or her to severance pay
or benefits under the Change in Control Severance Plan, and if the Retained DEFS
Employee executes a Release, then the Company shall reimburse Duke for the
lesser of (i) the amount of the cash severance paid to such individual under the
Change in Control Severance Plan and (ii) the applicable Severance Amount.
Further, in such event, the Company shall cause such Retained DEFS Employee (and
his or her covered dependents) to be provided with extended coverage under one
or more of the New Welfare Plans to the extent necessary to satisfy the
requirements of Section 6 of the Change in Control Severance Plan, and Duke
shall reimburse the Company for the cost of such extended coverage.

          (c) The Company and its Subsidiaries shall provide to each Transferred
PGC Employee whose employment terminates on or before the six-month anniversary
of the Closing Date cash severance benefits at least equal to the sum of the
applicable Severance Amount and the applicable Required Severance Amount,
subject to the execution by such Transferred PGC Employee of a Release.

          Section 4.3 PENSION BENEFITS. Effective as of the Closing Date,

          (b) The Company, Phillips and Duke shall take all reasonable steps
necessary and appropriate so that Continued Employees who participated in the
Phillips Savings Plans or the Duke Savings Plan, as applicable, and who have
loans outstanding from any such plan as of the Closing Date may continue to
repay such loans using voluntary payroll deductions from their paychecks from
the Company and its Subsidiaries.

          Section 4.5 WELFARE BENEFITS. Without limiting the generality of the
above provisions, this Section 4.5 contains certain specific provisions
regarding the provision of benefits under Welfare Benefit Plans, unemployment
compensation benefits and workers compensation benefits.

          (a) Effective as of the Closing Date, the Company shall cause the
Continued Employees to be eligible to be covered by such Welfare Benefit Plans
sponsored by the Company and/or one or more of its Subsidiaries as the Company
shall determine to implement.

          (b) Except as specifically provided in Section 4.5(d) below:
(i) Phillips and its Subsidiaries shall be solely responsible for (A) claims of
Transferred PGC Employees and their eligible beneficiaries and dependents for
workers compensation, unemployment compensation and under Welfare Benefit Plans
that are incurred before the Closing Date, and (B) claims relating to COBRA
Coverage attributable to "qualifying events" occurring on or before the Closing
Date with respect to any Transferred PGC Employees and their eligible
beneficiaries and dependents; (ii) Duke and its Subsidiaries shall be solely
responsible for (I) claims of Retained DEFS Employees and their eligible
beneficiaries and dependents for workers compensation, unemployment compensation
and under Welfare Benefit Plans that are incurred before the Closing Date, and
(II) claims relating to COBRA Coverage attributable to "qualifying events"
occurring on or before the Closing Date with respect to any Retained DEFS
Employees and their eligible beneficiaries and dependents; and (iii) the Company
and its Subsidiaries shall be solely responsible for (x) claims of Continued
Employees and their eligible beneficiaries and dependents for workers
compensation and unemployment compensation benefits and claims under Welfare
Benefit Plans that are incurred on or after the Closing Date, and (y) claims
relating to COBRA Coverage attributable to "qualifying events" occurring after
the Closing Date with respect to Continued Employees and their beneficiaries and
dependents. A medical/dental claim shall be considered incurred on the date when
the medical services are rendered or medical supplies are provided, and not when
the condition arose or when the course of treatment began. An unemployment
compensation or workers compensation claim shall be considered incurred before
the Closing Date if the occurrence leading up to the claim occurs before the
Closing Date.

          (c) Each Continued Employee who is employed on a regular basis shall
be immediately eligible to participate, without any waiting time, in any and all
Welfare Benefit Plans sponsored by the Company and its Subsidiaries for the
benefit of Continued Employees (such plans, collectively, the "NEW WELFARE
PLANS") to the extent coverage under such New Welfare Plan replaces coverage
under a comparable Phillips Plan or Duke Plan, in which such

                                       -7-
<PAGE>

Continued Employee was previously eligible to participate (such plans,
collectively, the "OLD WELFARE PLANS"). For purposes of each New Welfare Plan
providing medical, dental, pharmaceutical and/or vision benefits, the Company
shall cause all pre-existing condition exclusions and actively-at-work
requirements of such New Welfare Plan to be waived for Continued Employees and
their eligible beneficiaries and dependents, to the extent such exclusions and
restrictions did not apply under the applicable Old Welfare Plan, and the
Company shall cause any Eligible Expenses incurred by any Continued Employee and
his or her eligible beneficiaries and dependents during the portion of the plan
year of the Old Welfare Plan ending on the Closing Date, to be taken into
account under such New Welfare Plan for purposes of satisfying all deductible,
coinsurance and maximum out-of-pocket requirements applicable to such Continued
Employee and his or her eligible beneficiaries and dependents for the applicable
plan year as if such amounts had been paid in accordance with such New Welfare
Plan.

          (d) The Company shall establish one or more flexible spending plans
(collectively, the "NEW FSP") in which Continued Employees shall be eligible to
participate following the Closing Date. Phillips, Duke and the Company shall
take all reasonable steps necessary or appropriate so that the account balances
under the Phillips FSP or the Duke FSP, as applicable, of each Continued
Employee who has elected to participate therein in the year in which the Closing
Date occurs shall be transferred, as soon as practicable after the Closing Date,
from the Phillips FSP or the Duke FSP, as applicable, to the New FSP, and so
that the contribution elections of each such Continued Employee as in effect
immediately before the Closing Date remain in effect under the New FSP
immediately after the transfer of such account balance. If the aggregate amount
of the transferred account balances of Transferred PGC Employees or Retained
DEFS Employees is negative, then the Company shall pay Phillips or Duke, as
applicable, the amount of such aggregate negative balance promptly following
such account balance transfer. Notwithstanding the provisions of Section 4.5(b),
from and after the date a Continued Employee's FSP account is transferred in
accordance with this Section 4.5(d), the Company shall be solely responsible
for, and shall satisfy from the New FSP, all claims, whether incurred before, on
or after the Closing Date, for which such Continued Employee was entitled to
seek reimbursement under the Phillips FSP or the Duke FSP for the year in which
the Closing Date occurs.

                                  TAX BENEFITS

          Section 5.1 TAX BENEFITS GENERALLY. It is the intention of Phillips,
Duke and the Company that any tax deductions or other tax benefits associated
with any compensation or benefits payable to Continued Employees by any of them
be enjoyed by the party that bears the economic cost thereof, whether through
direct payment or provision of such compensation or benefits or through
reimbursement, and they agree to cooperate to ensure such result to the greatest
extent possible, through allocation of partnership deductions, adjustment of the
amounts of any reimbursement or otherwise.

the Company and the Corporation shall (and shall cause their respective
Subsidiaries to) cooperate with one another with respect to Tax matters. As soon

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

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

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

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

          Section 5.2 TREATMENT OF INDEMNITY PAYMENTS. Duke, Phillips and the
Company shall (and shall cause their respective Subsidiaries to) treat any
indemnity payment made pursuant to this Annex or the Contribution Agreement and
any payment made pursuant to Section 3.3 of the Contribution Agreement as an
adjustment to the cash distribution provided in Section 3.2(c)(1) or 3.2(c)(2),
as appropriate, of the Contribution Agreement, unless otherwise required
pursuant to a "determination" within the meaning of Code Section 1313(a).

          Section 5.3 TAX SHARING AGREEMENTS. Any Tax sharing agreement or
arrangement between Duke, on the one hand, and any DEFS Subsidiary, on the other
hand, shall be terminated as of the Closing Date and shall thereafter have no
further effect for any taxable year (whether the current year, a future year, or
a past year). Any Tax sharing agreement or arrangement between Phillips, on the
one hand, and any PGC Subsidiary, on the other hand, shall be terminated as of
the Closing Date and shall thereafter have no further effect for any taxable
year (whether the current year, a future year, or a past year).

          Section 5.4 ALLOCATION OF CERTAIN TAXES.

          (a) If any DEFS Subsidiary or PGC Subsidiary is permitted but not
required under applicable state, local or foreign Income Tax laws to treat
either the day before the Closing Date or the Closing Date as the last day of a
taxable period, then, solely for purposes of such state, local or foreign Income
Tax laws, such day shall be treated as the last day of a taxable period.

          (b) In the case of any Taxes that are imposed on a periodic basis and
are payable for a period that begins on or before the Closing Date and ends
after the Closing Date, the portion of such Tax that shall be allocable to the
portion of the period ending on the Closing Date shall (i) in the case of any
Taxes, other than Income Taxes and Taxes based upon or related to receipts, be
deemed to be the amount of such Taxes for the entire period, whether actually
paid before, during, or after such period, multiplied by a fraction the
numerator of which is the number of calendar days in the period ending on (and
including) the Closing Date and the denominator of which is the number of
calendar days in the entire period, and (ii) in the case of any Taxes based upon
or related to income or receipts (including but not limited to withholding
Taxes), be deemed equal to the amount which would be payable if the taxable year
ended on the close of business on the Closing Date; PROVIDED, HOWEVER, that any
franchise Tax measured by assets or capital shall be allocable to the taxable
period for which the right to do business obtained by the payment of such
franchise Tax relates, regardless of whether such franchise Tax

                                       -8-
<PAGE>

is measured by assets or capital relating to another taxable period. Clause (i)
of the preceding sentence shall be applied with respect to Taxes, if any, for
such period relating to capital (including net worth or long-term debt) or
intangibles by reference to the level of such items on the Closing Date. The
portion of any Taxes (or refunds) that are imposed on a periodic basis, payable
for a period that begins on or before the Closing Date and ends after the
Closing Date and not allocable to the portion of such period ending on the
Closing Date shall be allocable to the portion of the period beginning after the
Closing Date.

          (c) If the amount of any Tax described in Section 5.4(b), or any
refund thereof or credit therefor, is voluntarily redetermined or redetermined
by a Taxing Authority, the principles of Section 5.4(b) shall apply to the
amount as so redetermined.

          Section 5.5 PREDECESSORS AND SUCCESSORS. For purposes of this Annex,
any reference to a corporation shall include a reference to any limited
liability company into which such corporation is merged or converted and any
reference to a limited liability company shall include a reference to any
corporation which merged into, or was converted into, such limited liability
company; provided, however, that, notwithstanding the Merger, the Corporation
shall not be considered a PGC Subsidiary.

          Section 5.6 DUKE SUBSIDIARIES AND PGC SUBSIDIARIES. In the event that
the merger provided in Section 3.2 of the Governance Agreement occurs, then for
purposes of this Annex (other than Sections 6.1(e) and 6.2(e)), the term "DEFS
Subsidiary" shall include DEFS Holding, the term "PGC Subsidiary" shall include

from pursuing business opportunities that may have a competitive impact upon the
Company or (iii) to refrain from taking any other action that will or may be

shall, by virtue of the relationship established pursuant to the Transaction
Documents, have any other obligations to take or refrain from taking any other

vacancy of a Duke Pre-IPO Director, Duke shall cause the Duke Member to fill the

                                  ARTICLE III

                                    THE IPO

          Section 3.1  EFFORTS. The Company agrees to use its reasonable best
efforts to prepare for, effect and consummate the IPO (market conditions
permitting) as soon as practicable following the Contribution Closing, including
selecting underwriters, preparing and filing with the SEC a registration
statement and filings under applicable state securities or "blue sky" laws or
similar securities laws and determining the terms of the IPO; PROVIDED that,
notwithstanding anything to the contrary in this Agreement, the Company shall
not consummate any IPO on or before the date two years after the consummation of
the Contribution Closing without the prior written consent of Phillips if the
consummation of the IPO (including the potential effect of any underwriters'
over-allotment) in accordance with the provisions of this Agreement would result
in (i) Phillips' Corporation Interest being less than 20% upon consummation of
the IPO or (ii) an Enterprise Value immediately following the IPO of less than
$4,400,000,000; PROVIDED, FURTHER, that for purposes of the calculations
contemplated in (i) and (ii) in the preceding proviso, the "Average Market
Price" shall be the proposed public offering price of the Corporation Common
Stock in the IPO. Each of Duke and Phillips agree to (i) provide reasonable
assistance to the Company in effecting the IPO and (ii) cause any Duke
Shareholder or Phillips Shareholder, respectively, not to Transfer any or all of
their shares of Corporation Common Stock for a period of six months following
the consummation of the IPO and to agree to such other customary terms as are
reasonably requested by the underwriters in connection with the IPO.

          Section 3.2  FORMATION OF THE CORPORATION. Each of Duke and Phillips
agree to take such corporate action as is necessary and desirable to cause
Phillips Member Parent to be merged with and into the Duke Member, with the Duke
Member surviving (such surviving corporation, the "CORPORATION," and such
merger, the "MERGER"), immediately prior to the consummation of the IPO.
Phillips represents, warrants and agrees that at the time of such Merger, (i)
Phillips Member Parent shall have no assets or liabilities, contingent or
otherwise, other than through its ownership of its interest in Phillips Member
and (ii) Phillips Member shall

                                       -8-
<PAGE>

have no assets or liabilities, contingent or otherwise, other than through its
ownership of its interest in the Company. Duke represents, warrants and agrees
that at the time of the Merger, the Duke Member shall have no assets or
liabilities, contingent or otherwise, other than through its ownership of its
interest in the Company. Following the Merger and prior to the consummation of
the IPO, the percentage of the total number of issued and outstanding shares of
Corporation Common Stock owned by (i) Phillips and its Affiliates (other than
the Corporation and its Subsidiaries) shall equal the quotient, expressed as a
percentage, of (x) Phillips' Corporation Interest upon the consummation of the
IPO determined in accordance with Section 3.3(b)(2) divided by (y) the sum of
Phillips' Corporation Interest and Duke's Corporation Interest upon the
consummation of the IPO determined in accordance with Section 3.3(b)(2) and
Section 3.3(b)(3), respectively, and (ii) Duke and its Affiliates (other than
the Corporation and its Subsidiaries) shall equal the quotient, expressed as a
percentage, of (x) Duke's Corporation Interest upon consummation of the IPO
determined in accordance with Section 3.3(b)(3) divided by (y) the sum of Duke's
Corporation Interest and Phillips' Corporation Interest upon consummation of the
IPO determined in accordance with Section 3.3(b)(3) and Section 3.3(b)(2),
respectively. If necessary, for purposes of the above calculation only, Duke and
Phillips shall estimate in good faith the Average Market Price and the number of
shares of Corporation Common Stock to be sold to the public. Duke agrees to
cause the Duke Shareholder and Phillips agrees to cause the Phillips
Shareholder, respectively, to vote its shares to cause the Corporation upon
consummation of the IPO to have a single class of common stock (the "CORPORATION
COMMON STOCK") outstanding and no other classes of capital stock or other
securities (except for options to purchase shares of the Corporation Common
Stock issued to officers, directors and employees of the Corporation or the
Company or its Subsidiaries).

          Section 3.3  POST-IPO OWNERSHIP. (a) Each of Duke and Phillips
presently intends that, if the IPO occurs, approximately 20% of the Corporation
Common Stock shall be sold to the public by the Corporation pursuant to the IPO;
PROVIDED, HOWEVER, that this percentage may vary depending on market conditions
and other factors.

          (b) Each of Duke and Phillips agrees to take, or cause to be taken,
such action (including the Merger and any adjustments by the Corporation to the
number of shares of Corporation Common Stock owned by Duke and Phillips) as is
necessary and desirable to provide that upon the end of the fifth day of trading
on the NYSE (excluding the pricing day and without regard to the exercise of any
underwriters' over-allotment), each of Duke and Phillips shall own, directly or
indirectly, excluding any Corporation Common Stock purchased directly or
indirectly by either Party in the IPO, a percentage of the outstanding
Corporation Common Stock determined as follows:

               (1) For purposes of this Agreement, the following definitions
shall apply:

                    (A) "PUBLIC'S CORPORATION INTEREST" shall mean the quotient,
expressed as a percentage, of (x) the number of shares of the Corporation Common
Stock sold by the Company in the IPO (without giving effect to any underwriters'
over-allotment) divided by (y) the number of shares of Corporation Common Stock
outstanding immediately after the IPO (without giving effect to any
underwriters' over-allotment).

difference between (x) 100% and (y) the Public's Corporation Interest.

the quotient of (x) the Parties' Corporation Interest divided by (y) the
Public's Corporation Interest multiplied by (ii) the Public's Equity Value.

                    (E) "ENTERPRISE VALUE" shall mean the sum of (x) the
Parties' Equity Value and (y) $2,400,000,000; PROVIDED that, from and after the
date two years after the consummation of the Contribution Closing, "ENTERPRISE
VALUE" shall mean $5,500,000,000.

                    (F) "PHILLIPS ENTERPRISE VALUE" shall mean the product of
(x) the Enterprise Value and (y) .389.

                    (G) "PHILLIPS EQUITY VALUE" shall mean the difference
between (x) Phillips Enterprise Value and (y) $1,200,000,000.

                    (H) "TOTAL EQUITY VALUE" shall mean the quotient of (x) the
Public's Equity Value divided by (y) the Public's Corporation Interest.

               (2)  Phillips' Corporation Interest shall equal the quotient,
expressed as a percentage, of (x) Phillips Equity Value divided by (y) Total
Equity Value.

               (3)  Duke's Corporation Interest shall equal the difference
between (x) the Parties' Corporation Interest and (y) Phillips' Corporation
Interest.

          Annex B sets forth examples of determinations of Phillips'
Corporation Interest and Duke's Corporation Interest at various Public's Equity
Values. The percentages and calculations set forth in this Section 3.3 do not
give effect to any underwriters' over-allotment. In the event that there is an
underwriters' over-allotment and such over-allotment is exercised, each Party's
Corporation Interest and the interest of the public in the Corporation (prior to
such exercise) shall all be reduced pro rata.

and shall use reasonable best efforts to ensure that the auditors will issue

          Section 6.4  CONFIDENTIALITY. (a) Each Member and its respective
Affiliates shall keep confidential all information which is obtained by them as
Members or otherwise pursuant to this Agreement or any other Transaction

          (b)  The restrictions in Section 6.4(a) shall not apply to:

               (1)  information which enters the public domain otherwise than by

its Affiliates on terms no less strict than the terms of this Section 6.4;

               (6)  information requested by any Governmental Entity entitled by

exemption contained in this Section 6.4(b) shall provide such evidence as

                                       -14-
<PAGE>

the other Member may reasonably require to prove that the information sought to

under applicable securities laws or stock exchange regulations.

          (c)  The restrictions contained in Section 6.4(a) shall last until the
earlier of the consummation of the IPO and the date two years from the relevant
disclosure.

          Section 6.5  BUSINESS OPPORTUNITY UNDERSTANDING. Each of Duke and
Phillips presently intends that the Corporation shall be the primary vehicle by
which it conducts the midstream gas gathering and processing business in the
United States and Canada. However, in order to clarify any duties that Duke, as
the owner of a controlling interest in the Corporation, may owe to the
Corporation, the certificate of incorporation or bylaws of the Corporation (or
an agreement binding on the Corporation) shall contain a business opportunity
agreement substantially in the form of Annex D.

          Section 6.6  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, Duke 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 6.6. 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 Duke as its appraisal firm (the "DUKE APPRAISER").

          (b)  Within 15 days from the date of receipt of the Buy-Out Notice,
Phillips shall notify Duke 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 Phillips' 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 Phillips' 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 Duke and Phillips shall submit proposed Fair Market Values of
Phillips' Corporation Interest to the

                                       -15-
<PAGE>

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 Phillips' 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 6.6. 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 Duke and Phillips. The
Company shall provide to each of Duke and Phillips and, if applicable, the
Appraisal Committee, all information reasonably requested by them.

          (c)  The closing of Duke'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 6.6(b). The acquisition
shall be consummated at a closing held at the principal offices of the
Corporation (unless otherwise mutually agreed by Duke and Phillips) at which
time the purchase price, payable in the form of immediately available funds,
shall be delivered to Phillips, and Phillips shall deliver or cause to be
delivered to Duke such transfer documentation reasonably acceptable to Duke 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.

       CAPITAL ACCOUNTS, ALLOCATIONS OF PROFIT AND LOSS, DISTRIBUTIONS AND
                                  TAX STATUS

                                  ARTICLE VIII

                       LIQUIDITY AND TRANSFER RESTRICTIONS

          Section 8.1 STRUCTURE; TRANSFERS. For the period from the Contribution
Closing until the consummation of the IPO ("BLACKOUT PERIOD"), (i) Duke shall
cause the Duke Member to own and hold all of Duke's Company Interest and no
other assets or liabilities, and (ii) Phillips shall cause (A) the Phillips
Member to own and hold all of Phillips' Company Interest and no other assets or
liabilities and (B) Phillips Member Parent to own and hold all of the capital
stock of Phillips Member and no other assets or liabilities.

          Section 8.2  RIGHT OF FIRST OFFER. If either 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 (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 8.2, 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, (i) the
Transferring Entity shall execute and deliver to the purchasing Non-Transferring
Entity (A) an assignment of the Corporation Interest described in the Transfer
Notice, in form and substance reasonably acceptable to the purchasing
Non-Transferring Entity and (B) any other instruments reasonably requested by
the purchasing Non-Transferring Entity to give effect to the purchase; and (ii)
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 not elect to purchase the Corporation Interest
pursuant to this Section 8.2, or having elected to so purchase such Corporation
Interests fails to do so within the time period required by this Section 8.2,
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

                                       -17-
<PAGE>

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 (c)).

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 8.2 shall apply anew to any further efforts by the Transferring
Entity to Transfer its Corporation Interest.

          Section 8.3  CHANGE OF CONTROL. (a) If (i) a Change of Control occurs
with respect to the Duke Member (prior to the IPO) or a Duke Shareholder,
Phillips shall have the option to purchase such Duke Member's Company Interest
(prior to the IPO) or such Duke Shareholder's Corporation Interest (following
the IPO), as the case may be, for Fair Market Value pursuant to the provisions
of Section 8.3(b), (c) and (d), and (ii) a Change of Control occurs with respect
to the Phillips Member (prior to the IPO) or a Phillips Shareholder, Duke shall
have the option to purchase such Phillips Member's Company Interest (prior to
the IPO) or such Phillips Shareholder's Corporation Interest (following the
IPO), as the case may be, pursuant to the provisions of Section 8.3(b), (c) and
(d).

          (b)  In the event of a transaction giving rise to a Change of Control
with respect to the Duke Member (prior to the IPO), Duke Shareholder, Phillips
Member (prior to the IPO) or Phillips Shareholder, as applicable, the Party who
has (or whose Subsidiaries have) 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 (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
Company Interest or 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 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 Non-Changing Party is Duke, the Non-Changing Party
Appraiser shall be Deloitte &

                                       -18-
<PAGE>

Touche L.L.P., or, if the Non-Changing Party is Phillips, the Non-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 Non-Changing Party of
the Control Notice, the Control Appraiser Committee shall consist solely of the
Non-Changing Party Appraiser. If applicable, 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 Company Interest or Corporation Interest,
as the case may be, 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 8.3. 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 Company Interest or
Corporation Interest, as the case may be, 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 Duke and Phillips. 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 Company Interest or Corporation Interest, as the case may be,
shall be consummated on or before the 60th day after the determination of the
Fair Market Value in accordance with Section 8.3(c). The acquisition shall be
consummated at a closing held at the principal offices of the Company or 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
such transfer documentation reasonably acceptable to the Non-Changing Party as
shall be required to evidence the transfer of the Changing Party's Company
Interest or Corporation Interest, as the case may be, free and clear of all
liens and encumbrances, except those created under this Agreement.

<PAGE>

          (e) Each of Duke and Phillips agrees that prior to consummation of the
IPO, as a condition to the consummation of any transaction that will result in a
Change of Control of the Duke Member or the Phillips Member, respectively, it
will cause the new Parent of the Duke Member or the Phillips Member,
respectively, to assume the obligations of Duke or Phillips, as applicable,
under this Agreement.

          Section 8.4  OPEN MARKET PURCHASES AND TRANSFERS POST-IPO. In and
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 8.5  REGISTRATION RIGHTS. Each of Duke and Phillips agrees to
take such corporate action as is necessary and desirable to cause the
Corporation to enter into a registration rights agreement which shall grant each
Party the registration rights set forth in this Section 8.5, and shall contain
other customary and reasonable terms and conditions.

          (a)  DEMAND REGISTRATIONS. At any time following the six-month
anniversary of the IPO, each of the Parties shall have the right on two
occasions to request the Corporation to file a registration statement under the
Securities Act in respect of all or a portion of the shares of Corporation
Common Stock owned by it or its Affiliates (excluding the Corporation and its
Subsidiaries) (so long as such request covers at least 3% of the shares of
Corporation Common Stock then-outstanding) (a "DEMAND REQUEST"). Subject to
customary exceptions, (including any period within 60 days prior to, and 180
days (or such shorter period as may be agreed to by the underwriters) after the
effective date of, a Corporation-initiated registration, and any period of up to
180 days if the Corporation Board determines that filing of the registration
statement would require disclosure of pending matters or information the
disclosure of which would likely be detrimental to the Corporation or materially
interfere with its business or pending transaction), as promptly as practicable,
but in no event later than 60 days after the Corporation receives a Demand
Request, the Corporation shall file with the SEC and thereafter use its
reasonable best efforts to cause to be promptly declared effective (and kept
effective for the lesser of 90 days or until all shares registered have been
sold) a registration statement (a "DEMAND REGISTRATION") providing for the
registration of at least such number of shares of Corporation Common Stock as
such Party shall have demanded be registered.

          (b) PIGGYBACK REGISTRATION. If, at any time following the IPO, the
Corporation proposes to register any shares of Corporation Common Stock under
the Securities Act on a registration statement on Form S-1, Form S-2 or Form S-3
(or successor forms) (whether or not pursuant to a Demand Registration under
Section 8.5(a)), subject to customary limitation and proration provisions, the
Corporation shall give each Party (or its Subsidiaries, if applicable) the
opportunity to include such Party's shares of Corporation Common Stock in such
registration statement.

          (c) OTHER REGISTRATION PROVISIONS. Other provisions will include:
customary indemnification by the Corporation for liabilities incurred under
Federal and state securities laws; the agreement by holders of shares of
Corporation Common Stock who own more than 5% of the shares of Corporation
Common Stock outstanding or whose shares are included in the registration
statement (in each case if requested by the underwriters) not to sell any shares
of the Corporation Common Stock for a period of up to 90 days following the
effective date of the

                                       -20-
<PAGE>

registration statement; that all registration expenses, except the underwriting
discounts and fees of counsel for the Party, will be borne by the Corporation;
registration rights may only be transferred to transferees who after the
transfer hold at least 10% of the outstanding Corporation Common Stock; that the
Corporation may preempt any demand registration with a primary registration; and
that the underwriter in any demand registration shall be selected by the holders
of 2/3 of the shares being covered by the Demand Request but must be acceptable
to the Corporation. For purposes of exercise of Demand Requests, transferees
shall be included with Duke or Phillips, as the case may be, based on who was
the original transferor of such shares.

          Section 8.6  ANTI-DILUTION. If, at any time following the IPO, the
Corporation offers or issues additional shares of the Corporation Common Stock
or additional shares of any other previously issued and outstanding capital
stock in a public offering, each Party shall have the opportunity to subscribe
for and purchase such number of shares of the Corporation Common Stock or such
other capital stock, as the case may be, such that such Party's Corporation
Interest or ownership percentage of such capital stock, as the case may be,
following the offering or issuance remains equal to such Party's Corporation
Interest or ownership percentage of such capital stock, as the case may be,
immediately prior to the offering or issuance.

          Section 8.7  VOID TRANSFERS. Any purported Transfer of all or any
portion of a Company Interest or Corporation Interest not permitted by this
Article VIII shall be void. The provisions of this Article VIII with respect to
Company Interests and Corporation Interests shall apply equally to any rights or
options to purchase, or securities convertible into or exchangeable for, the
Company Interests or Corporation Interests.

                                   ARTICLE IX

                                  TERMINATION

          Section 9.1  SURVIVAL OF AGREEMENT; TERM. Except as set forth below,
this Agreement shall not be terminated or amended, nor any provision hereof
waived, except by an instrument in writing signed by each of the parties hereto.
Notwithstanding the foregoing, any provision of this Agreement which
specifically provides for termination of such provision on an earlier date shall
terminate on such other date.

          Section 9.2  TERMINATION. (a) This Agreement shall be terminated
immediately upon the termination of the Contribution Agreement in accordance
with its terms.

          (b) (i) On or prior to the Contribution Closing Date, the provisions
hereof applicable or relating to the Company shall be incorporated into the
amended limited liability company agreement of the Company (the "LLC AGREEMENT")
prepared pursuant to Section 2.1 of the Contribution Agreement, and upon
execution thereof at the Contribution Closing, such provisions hereof applicable
or relating to the Company and incorporated into the LLC Agreement shall
terminate and cease to be effective. Any provisions hereof applicable or
relating to both the Company and the Corporation shall be incorporated into the
LLC Agreement only as, and to the extent, they apply or relate to the Company
and shall terminate and cease to be effective only in that regard and to such
extent.

          (ii) On or prior to the consummation of the IPO, Duke and Phillips
shall execute and deliver a shareholders agreement and a registration rights
agreement which incorporate all provisions hereof applicable or relating to the
Corporation, both of which shall become effective upon the consummation of the
IPO. The shareholders agreement shall survive until either Duke's Total
Corporation Interest or Phillips' Total Corporation Interest is less than 20%,
and the registration rights under the registration rights agreement shall
survive as to Duke until Duke's Corporation Interest is less than 10% and as to
Phillips until Phillips' Corporation Interest is less than 10%. Upon compliance
with this Section 9.2(b) and the effectiveness of both such agreements, the
provisions of this Agreement incorporated into such agreements shall terminate.

          (c)  In the case of termination or partial termination in accordance
with this Section 9.2, upon such termination, this Agreement or the appropriate
provisions shall become void and have no effect; PROVIDED, HOWEVER, that such
termination shall not relieve any party hereto of any liability for any breach
of this Agreement or such provisions that occurred prior to such termination.

                                 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 party 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 or the Contribution
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
party hereto 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 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, 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 this Agreement and the Contribution Agreement.

<PAGE>

party hereto may, only by an instrument in writing, waive compliance by the
other party hereto with any term or provision of this Agreement on the part of
such other party hereto to be performed or complied with. The waiver by any
party hereto of a breach of any term or provision of this Agreement shall not be
construed as a waiver of any subsequent breach. Except as otherwise expressly
provided herein, no failure to exercise, delay in exercising or single or
partial exercise of any right, power or remedy by any party, and no course of
dealing between the parties, shall constitute a waiver of any such right, power
or remedy.

be held invalid, illegal or unenforceable, the validity, legality or
enforceability of the other provisions of this Agreement shall not be affected

valid, legal and enforceable provision as similar as possible to the provision
at issue.

          Section 10.10 INTERPRETATION. The phrase "including" shall be deemed
to be followed by "without limitation." In the event an ambiguity or question of

favoring or disfavoring any party by virtue of the authorship of any provisions
of this Agreement.

          Section 10.11 SPECIFIC PERFORMANCE. The parties hereto agree that
irreparable damage would occur in the event that any party fails to consummate
the transactions contemplated by this Agreement in accordance with the terms of
this Agreement and that the parties shall be entitled to specific performance in

                       SPECIFIC PRE-IPO GOVERNANCE ISSUES

1.   Compensation policies for employees of the Company, including specific
     compensation and benefit plans and programs, to the extent such
     policies are of the type that would customarily be considered by a
     compensation committee of the board of directors of a comparably sized,
     publicly-traded corporation; PROVIDED, HOWEVER, that these policies
     shall not include the hiring and firing and compensation of senior
     officers and managers, evaluating their performance and planning for
     their succession.

2.   Entering a new line of business outside of the midstream gas gathering,
     processing, marketing and transportation businesses (and directly
     related activities) in the United States and Canada.

4.   Distributions and dividends (other than tax distributions as set forth
     in Section 3.6(a)(i) of Annex F and the distributions described in
     Section 3.2(c) of the Contribution Agreement) prior to the IPO.

5.   The following transactions:

     a)    Any merger, consolidation, recapitalization, acquisition,
           divestiture, joint venture or alliance (or a related series of
           such transactions) involving the acquisition or expenditure
           (in the form of cash or otherwise) of in excess of
           $100,000,000 in value to or from the Company;

      b)   Any shut-down of a facility having a fair market value in excess of
           $100,000,000;

      c)   Entering into any sales contract or commitment that has a term
           of 5 years or more and that involves annual revenues to the
           Company in excess of 5% of the Company's total annual sales
           revenues for the most recently completed fiscal year;

      d)   Admittance of any new member/equity holder in the Company
           prior to the IPO (it being understood that the IPO is not
           subject to Section 2.5(b));

      e)   Requirement of any additional capital contribution by either Member;
           and

      f)   Liquidation or dissolution of the Company.

6.    Any capital expenditure in excess of $100,000,000 (other than a capital
      expenditure to effect any merger, consolidation, recapitalization,
      acquisition, divesture, joint venture or alliance).

7.    Any borrowing in excess of $200,000,000 (other than borrowings described
      in clauses (i) through (iii) of Section 6.17 of the Contribution
      Agreement).


<PAGE>

8.    The settlement of any action or claim against the Company involving
      payment by the Company of in excess of $25,000,000, excluding amounts
      covered or reimbursed by insurance.

9.    Entering into transactions with either Party or Affiliates of either
      Party on terms that are clearly less favorable than those terms that
      are within the range of comparable transactions between unaffiliated
      third parties.

If a particular action that the Company proposes to take is reflected in an
operating or capital budget of the Company that has been approved by four or
more directors, no further approval of such action is required before it may be
taken, notwithstanding the inclusion of such action in this Annex A.

                        BUSINESS OPPORTUNITIES AGREEMENT

          1.  SCOPE OF BUSINESS OF THE CORPORATION AND ITS SUBSIDIARIES. The
Corporation agrees that, except with the consent of Duke (which consent Duke may
withhold in its sole discretion and which it shall have no duty, fiduciary or
otherwise, to grant), the Corporation and its Subsidiaries will not engage in
any business other than the midstream gas gathering, processing, marketing and
transportation business in the United States and Canada (the "DESIGNATED
BUSINESS"). The Corporation hereby renounces any interest or expectancy in any
Business Activity that does not consist exclusively of the Designated Business.

           2.  CORPORATE OPPORTUNITIES. (a) In anticipation that Duke is
currently, and 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
officers and directors of the Corporation), the provisions of this Business
Opportunities Agreement 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
opportunity, transaction, or other matter (each a "BUSINESS ACTIVITY") in which
Duke engages or seeks to engage, PROVIDED that such Business Activity is
conducted by Duke in accordance with the standards in paragraph 3 below. 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 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

<PAGE>

          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 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
hereby renounces 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 these Business
Opportunities provisions shall allow any Duke Post-IPO Director to pursue a
Business Activity in the Designated Business solely for his or her personal
benefit (as opposed to for the benefit of Duke).

          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.

          5.   INTERPRETATION.  For purposes of this Annex D, "Duke" shall
include all Subsidiaries and Affiliates of Duke (other than the Corporation and
its Subsidiaries).

          6.   AMENDMENT. Any proposed amendment to these provisions shall
require the approval of at least a majority of the members of the Corporation
Board who are not officers, directors or employees of Duke and who are otherwise
disinterested or of a committee of the Corporation Board consisting exclusively
of directors of the Corporation who are not officers, directors or employees of
Duke and who are otherwise disinterested.

          7. TERM. The provisions of this Annex D shall terminate at such time
as Duke no longer owns, directly or indirectly, a majority of Corporation Common
Stock and no longer otherwise controls the Corporation, directly or indirectly.

make special allocations to the extent required pursuant to Article V of Annex A
to the Contribution Agreement.

          Section 3.2  LIMITATIONS ON ALLOCATIONS.

          Notwithstanding the general allocation rules set forth in Section 3.1
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

                                       -7-
<PAGE>

Profits, Losses, other items or distributions pursuant to this Annex F, 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 3.1(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 3.1(b) hereof, the limitation set forth in this Section 3.2(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
Annex F 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 3.2(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 III have been made as if this
Section 3.2(b) were not in this Annex F. This Section 3.2(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 3.2(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

                                       -8-
<PAGE>

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 3.2(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 3.2(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 3.2, 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 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 3.2(h).
Therefore, notwithstanding any other provision of this Article III (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 Annex F and
all Company items were allocated pursuant to Section 3.1 hereof.

          Section 3.3  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 3.4  INTERIM ALLOCATIONS RELATING TO TRANSFERRED COMPANY
INTERESTS.

          Notwithstanding any other provision of this Annex F or the
Governance 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 interest in

                                       -9-
<PAGE>

the Company during a Fiscal Year, the allocations required under this Article
III 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 3.4 shall also apply for purposes of computing a Member's
Capital Account.

          Section 3.5  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 3.5(a).

          (c)  Allocations pursuant to this Section 3.5 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 3.1 or 3.2.

          Section 3.6  DISTRIBUTIONS.

          (a)  DISTRIBUTIONS OTHER THAN IN LIQUIDATION OF THE COMPANY.  Except
as provided in Section 3.6(b) below (and taking into account deemed
distributions, if any, under Section 4.1 which are not re-contributed pursuant
to Section 4.1), 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

                                       -10-
<PAGE>

     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 as permitted by the Governance Agreement.

     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 Annex F, 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 IV

                WITHHOLDING TAX MATTERS; TAX STATUS AND TREATMENT

          Section 4.1  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 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, without limitation, 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

                                       -11-
<PAGE>

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 4.1 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 4.2  TAX STATUS.

          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) (the "FLOW THROUGH SUBSIDIARIES") is intended
to be treated as a partnership or disregarded entity for U.S. Federal income tax
purposes. Each of Duke, Phillips, 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: (A) the treatment of
the Company (or any successor thereto) as a partnership for U.S. Federal income
tax purposes and the treatment of each of the Flow Through Subsidiaries (or any
successor thereto) as a partnership or disregarded entity for U.S. Federal
income tax purposes; (B) the treatment of the Company as not a publicly traded
partnership for United States Federal income tax purposes; (C) 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; (D) 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) 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; (E) 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 the Contribution
Agreement (as adjusted pursuant to Section 3.3) (the "PGC DISTRIBUTION") as a
distribution pursuant to Code Section 731 and the treatment that, for purposes
of the Code, neither the PGC 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 (E) that,
Duke, Phillips, 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 shall treat 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

                                       -12-
<PAGE>

the value of the property contributed in the PGC Contribution, such value being
for this purpose $2,139,500,000); and (F) the treatment of the merger of
Phillips Member Parent into DEFS Holding pursuant to Section 3.2 of the
Governance Agreement as a "reorganization" within the meaning of Section 368(a)
in which no gain or loss is recognized to PGC, DEFS Holding, the Company, Duke,
Phillips or any other Person.

(iii) to the extent pursuant to a divestiture required by Section 6.2 of the

and after the date hereof and until the Closing Date, except (i) for the mergers

other transactions specifically provided for in the Governance Agreement or the
Contribution Agreement (so long as such transactions do not result in a non-U.S.
entity owning any PGC Subsidiary that is a United States person within the
meaning of the Code or any assets thereof), (ii) as consented to or approved by
Duke in writing, and (iii) to the extent pursuant to a divestiture required by
Section 6.2 of the Contribution Agreement, Phillips shall not, and shall cause
the PGC Subsidiaries not to, cause any change to or restructuring of the
ownership interests in the entities that are PGC Subsidiaries as of the date
hereof.

          (c)  For the period, if any, beginning at the time of consummation of
the IPO and ending on the second anniversary of the Closing Date, without the
prior written consent of Duke and Phillips: (i) the Company shall not make (or
enter into a plan or arrangement to make) any Distributions of cash or other
property to PGC in excess of the product of the aggregate Distribution to all
Members and PGC's Percentage Interest as of the Closing Date, (ii) the Company
shall not make (or enter into a plan or arrangement to make) any Distribution to
PGC of cash or other property other than Distributions to fund dividends by the
Corporation to its shareholders and Distributions pursuant to Section 3.6(a)(i)
hereof and (iii) PGC shall not be liquidated, shall not be merged into the
Corporation, shall not distribute to any shareholder of PGC the Company Interest

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

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 4.4(e) shall be allocated

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

capacity as a direct or indirect shareholder, or affiliate of such a
shareholder, of the Corporation).

          (f)  COOPERATION AND EXCHANGE OF INFORMATION. Duke, Phillips, the
Company and the Corporation shall (and shall cause their respective Subsidiaries

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

                                       -15-
<PAGE>

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 the
Corporation 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 4.4(f) shall cease to apply with respect to
taxable periods beginning after the consummation of the IPO, except to the

        DUKE ENERGY AND PHILLIPS PETROLEUM ANNOUNCE DEFINITIVE AGREEMENT
              FORMING PREMIER GAS GATHERING AND PROCESSING COMPANY

    DUKE ENERGY AND PHILLIPS PETROLEUM EACH TO RECEIVE $1.2 BILLION IN CASH;
                           IPO PLANNED FOR NEW COMPANY

BARTLESVILLE, Okla., Dec. 16, 1999 --- Phillips Petroleum (NYSE: P) and Duke
Energy (NYSE: DUK) today announced that they have signed definitive agreements
to combine Duke Energy's gas gathering and processing businesses and Phillips
Petroleum's Gas Processing and Marketing (GPM) unit to form a new midstream
company to be called Duke Energy Field Services (DEFS). This new company will
become the nation's largest midstream natural gas liquids business and the
premier gatherer and processor of natural gas in the continental United States,
with an expected enterprise value of between $5 billion and $6 billion. The
definitive agreements have been unanimously approved by both companies' boards
of directors. Due diligence has been completed. The transaction is expected to
close by the end of the first quarter 2000, subject to regulatory approval.

Under the terms of the agreement, the new company will seek to arrange
$2.4 billion of debt financing and, upon closing of the transaction, will make
one-time cash distributions of $1.2 billion to both Duke Energy and Phillips
Petroleum. In addition, the existing NGL arrangements between Phillips Petroleum
and GPM will be maintained by the new company for an initial term of fifteen
years. At closing, Duke Energy will own about 70 percent of the new company, and
Phillips Petroleum will own about 30 percent.

During the first half of 2000, following completion of the transaction and
subject to market conditions, it is expected that the new company will offer
approximately 20 percent of its equity to the public in an initial public
offering. The proceeds of the offering will be used to reduce debt incurred by
the new company in the transaction. DEFS will provide investors the opportunity
to participate directly in the future growth and consolidation of the gas
gathering and processing industry. Given the company's size and access to the
capital markets, it will immediately have the flexibility to pursue its growth
opportunities.

The agreements governing DEFS set forth a formula which adjusts Duke Energy's
and Phillips Petroleum's post-IPO equity interests depending on the public
market valuation of the new company. Accordingly, assuming a value range for the
new company between $5 billion and $6 billion, Duke Energy's post-IPO equity
ownership in the new company would range between 55 and 57 percent, and Phillips
Petroleum's post-IPO ownership would range between 23 and 25 percent. Duke
Energy expects to consolidate the new company for financial reporting purposes;
Phillips Petroleum expects to account for its ownership in DEFS on an equity
basis.

Transaction Accretive to Both Duke Energy and Phillips Petroleum

The transaction will be immediately accretive to both Duke Energy and Phillips
Petroleum.

The transaction will help move Duke Energy toward the top of its targeted range
for growing earnings per share 8-10 percent annually. The $1.2 billion cash
payment will reduce the need for Duke Energy to issue equity to fund its capital
expenditure plans. Duke Energy is firmly focused on becoming the world's premier
global energy merchant.

Phillips Petroleum expects to retain approximately $1.15 billion, after taxes,
of the $1.2 billion that it will receive from this transaction. Phillips
Petroleum's proceeds from the transaction will be used initially to reduce debt,
as well as for other corporate purposes. As a result, Phillips Petroleum expects
its net debt-to-capital ratio to decline from 47 percent to approximately
40 percent.

Richard B. Priory, chairman, president and chief executive officer of Duke
Energy, said, "This innovative transaction demonstrates our ability to seize
opportunities for growth and value creation. This transaction is the most recent
and vivid example of Duke Energy's global energy merchant strategy. As the
energy industry changes, there will be opportunities for those companies with
the expertise, financial strength and assets to act quickly, decisively and
creatively.

"All of our energy businesses are top tier performers. By combining the assets
and people of Duke Energy's gas gathering and processing business with GPM, we
are building a new market leader. And, with the prospect of an IPO, we'll tap
new financing and ownership opportunities that will unlock the full value of the
new company," Priory said.

James J. Mulva, chairman, president and chief executive of Phillips Petroleum,
stated, "This transaction is an integral step in achieving our strategic
objectives recently communicated to the financial community. It monetizes a
substantial portion of the value of one of Phillips Petroleum's key non-E&P
assets, thereby increasing Phillips Petroleum's financial flexibility to pursue
attractive exploration and production growth opportunities. It also enhances and
makes more transparent the value of our GPM asset.

"In Duke Energy, we have a company that intends to capture the potential in this
business and has an excellent record as both an operator of assets and a builder
of value. We are also maintaining both financial and operational integration
between Phillips Petroleum and the midstream business. Financially, Phillips
Petroleum will hold a significant ownership position in a publicly held
midstream company, with a strong growth platform of high quality assets,
financial resources and strong management. We believe the new company will have
greater access to capital to grow its business than the GPM unit historically
obtained as part of Phillips Petroleum. Operationally, we have ensured a
continued NGL supply for our downstream businesses," Mulva concluded.

About the New Duke Energy Field Services

The new company will have a strong position in most of the significant
hydrocarbon basins in the continental United States. The combined revenues and
EBITDA for the two businesses in the third quarter of 1999 was $1.6 billion and
$183 million, respectively. The new company will operate 67 plants and 57,000
miles of pipelines, and have an estimated17 TCF of contracted supply. It will
process approximately 5 BCFD of raw gas, and produce 400,000 BPD of NGL. Duke
Energy and Phillips Petroleum believe that the new company will realize
synergies, primarily from operating efficiencies.

James W. Mogg, currently president of Duke Energy's gathering and processing
business (also called Duke Energy Field Services), will become chairman,
president, and chief executive officer of the new company. Michael J. Panatier,
currently president and chief executive of GPM will become vice chairman.

"This combination represents the latest and most dramatic example of the
restructuring and consolidation in the midstream gas business. It immediately
creates shareholder value for both Duke Energy and Phillips Petroleum. By
combining DEFS and GPM's businesses, we will have the best collection of people
and assets in the gathering and processing industry. This transaction brings
together the fastest growing midstream business, DEFS, with one of the most
experienced, GPM. Additionally, Phillips Petroleum's assets and gas contracts
provide additional balance to our existing business," said Mogg.

The new company will be governed by a board of directors which will initially
consist of 3 directors to be chosen by Duke Energy and 2 directors to be
selected by Phillips Petroleum. Messrs. Priory and Mulva, have agreed to serve
on the DEFS board. Following the IPO, the board will be expanded from 5 to 11;
Duke Energy will choose 7 members (2 of whom will be independent) and Phillips
Petroleum will choose 4 (1 of whom will be independent).

DEFS will be headquartered in Denver, Colorado.

UPR's natural gas gathering, processing, fractionation and NGL pipelines for
$1.35 billion. The company operates 52 plants today in Wyoming, Colorado,
Kansas, Oklahoma, New Mexico, Texas, along the Gulf Coast and in northwestern
Alberta, Canada.

Phillips Petroleum's NGL business, GPM, has operated Phillips Petroleum's gas
gathering and processing units in the continental United States since 1992. GPM
operates 15 plants in Texas, New Mexico and Oklahoma.

The NGL industry provides processing of natural gas and fractionation of natural
gas liquids to produce liquid products such as ethane, propane, butanes and
natural gasolines. Customers of the NGL business include gas and crude
producers, refineries, petrochemical plants and propane distributors.

Morgan Stanley Dean Witter acted as financial advisor to Duke Energy and Merrill
Lynch & Co. acted as financial advisor to Phillips Petroleum.
