the Chief Executive Officer of the Company, subject to such limitations on such

any Award previously granted to, a person who is an officer subject to Rule

designate Participants; (ii) determine the type or types of Awards to be granted
to a Participant; (iii) determine the number of Units to be covered by Awards;
(iv) determine the terms and conditions of any Award; (v) determine whether, to
what extent, and under what circumstances Awards may be settled, exercised,
canceled, or forfeited; (vi) interpret and administer the Plan and any
instrument or agreement relating to an Award made under the Plan; (vii)
establish, amend, suspend, or waive such rules and regulations and appoint such
agents as it shall deem appropriate for the proper administration of the Plan;
and (viii) make any other determination and take any other action that the
Committee deems necessary or desirable for the administration of the Plan.
Unless otherwise expressly provided in the Plan, all designations,
determinations, interpretations, and other decisions under or with respect to
the Plan or any Award shall be within the sole discretion of the Committee, may
be made at any time and shall be final, conclusive, and binding upon all
Persons, including the Company, the Partnership, any Affiliate, any Participant,
and any beneficiary of any Award.

      SECTION 4. Units

      (a) Units Available. Subject to adjustment as provided in Section 4(c),
the number of Units with respect to which Awards may be granted under the Plan
is 700,000. If any Option or Phantom Unit is forfeited or otherwise terminates
or is canceled without the delivery of Units, then

                                      -3-
<PAGE>

the Units covered by such Award, to the extent of such forfeiture, termination
or cancellation, shall again be Units with respect to which Awards may be
granted.

      (b) Sources of Units Deliverable Under Awards. Any Units delivered
pursuant to an Award shall consist, in whole or in part, of Units acquired in
the open market, from any Affiliate, the Partnership or any other Person, or any
combination of the foregoing.

      (c) Adjustments. In the event that the Committee determines that any
distribution (whether in the form of cash, Units, other securities, or other
property), recapitalization, split, reverse split, reorganization, merger,
consolidation, split-up, spin-off, combination, repurchase, or exchange of Units
or other securities of the Partnership, issuance of warrants or other rights to
purchase Units or other securities of the Partnership, or other similar
transaction or event affects the Units such that an adjustment is determined by
the Committee to be appropriate in order to prevent dilution or enlargement of
the benefits or potential benefits intended to be made available under the Plan,
then the Committee shall, in such manner as it may deem equitable, adjust any or
all of (i) the number and type of Units (or other securities or property) with
respect to which Awards may be granted, (ii) the number and type of Units (or
other securities or property) subject to outstanding Awards, and (iii) the grant
or exercise price with respect to any Award or, if deemed appropriate, make
provision for a cash payment to the holder of an outstanding Award; provided,
that the number of Units subject to any Award shall always be a whole number.

      SECTION 5. Eligibility.

      Any Employee or Director shall be eligible to be designated a Participant
and receive an Award under the Plan.

      SECTION 6. Awards.

      (a) Options. The Committee shall have the authority to determine the
Employees and Directors to whom Options shall be granted, the number of Units to
be covered by each Option, the purchase price therefor and the conditions and
limitations applicable to the exercise of the Option, including the following
terms and conditions and such additional terms and conditions, as the Committee
shall determine, that are not inconsistent with the provisions of the Plan.

            (i) Exercise Price. The purchase price per Unit purchasable under an
      Option shall be determined by the Committee at the time the Option is
      granted and may be more or less than its Fair Market Value as of the date
      of grant.

            (ii) Time and Method of Exercise. The Committee shall determine the
      Restricted Period, i.e., the time or times at which an Option may be
      exercised in whole or in part, which may include, without limitation,
      accelerated vesting upon the achievement of specified performance goals,
      and the method or methods by which payment of the exercise price with
      respect thereto may be made or deemed to have been made, which may
      include, without limitation, cash, check acceptable to the Company, a
      "cashless-broker" exercise through

                                      -4-
<PAGE>

      procedures approved by the Company, other securities or other property, or
      any combination thereof, having a Fair Market Value on the exercise date
      equal to the relevant exercise price.

            (iii) Forfeiture. Except as otherwise provided in the terms of the
      Option grant, upon termination of a Participant's employment with the
      Company and its Affiliates or membership on the Board, whichever is
      applicable, for any reason during the applicable Restricted Period, all
      Options shall be forfeited by the Participant. The Committee may, in its
      discretion, waive in whole or in part such forfeiture with respect to a
      Participant's Options.

      (b) Phantom Units. The Committee shall have the authority to determine the
Employees and Directors to whom Phantom Units shall be granted, the number of
Phantom Units to be granted to each such Participant, the Restricted Period, the
conditions under which the Phantom Units may become vested or forfeited, which
may include, without limitation, the accelerated vesting upon the achievement of
specified performance goals, and such other terms and conditions as the
Committee may establish with respect to such Awards, including whether DERs are
granted with respect to such Phantom Units.

            (i) DERs. To the extent provided by the Committee, in its
      discretion, a grant of Phantom Units may include a tandem DER grant, which
      may provide that such DERs shall be paid directly to the Participant, be
      credited to a bookkeeping account (with or without interest in the
      discretion of the Committee) subject to the same vesting restrictions as
      the tandem Award, or be subject to such other provisions or restrictions
      as determined by the Committee in its discretion.

            (ii) Forfeiture. Except as otherwise provided in the terms of the
      Phantom Units grant, upon termination of a Participant's employment with
      the Company and its Affiliates or membership on the Board, whichever is
      applicable, for any reason during the applicable Restricted Period, all
      Phantom Units shall be forfeited by the Participant. The Committee may, in
      its discretion, waive in whole or in part such forfeiture with respect to
      a Participant's Phantom Units.

            (iii) Lapse of Restrictions. Upon or as soon as reasonably practical
      following the vesting of each Phantom Unit, subject to the provisions of
      Section 8(b), the Participant shall be entitled to receive from the
      Company one Unit or cash equal to the Fair Market Value of a Unit, as
      determined by the Committee in its discretion.

      (c)   Performance Awards. The Committee is authorized to grant Performance
            Awards to Participants on the following terms and conditions:

            (i)   Right to Payment. A Performance Award shall confer upon
                  Participant rights, valued as determined by the Committee, and
                  payable to, or exercisable by, the Participant to whom the
                  Performance Award is granted, in whole or in part, as the
                  Committee shall establish at grant or thereafter. The
                  performance criteria and all other terms and conditions of the
                  Performance Award shall be

                                      -5-
<PAGE>

                  determined by the Committee upon the grant of each Performance
                  Award or thereafter.

            (ii)  Other Terms. A Performance Award may be denominated or payable
                  in cash, deferred cash, Units, other Awards or other property,
                  and other terms of Performance Awards shall be, as determined
                  by the Committee.

      (d)   General.

            (i)   Awards May Be Granted Separately or Together. Awards may, in
                  the discretion of the Committee, be granted either alone or in
                  addition to, in tandem with, or in substitution for any other
                  Award granted under the Plan or any award granted under any
                  other plan of the Company or any Affiliate. Awards granted in
                  addition to or in tandem with other Awards or awards granted
                  under any other plan of the Company or any Affiliate may be
                  granted either at the same time as or at a different time from
                  the grant of such other Awards or awards.

            (ii)  Limits on Transfer of Awards.

                  (A) Except as provided in (C) below, each Option shall be
            exercisable only by the Participant during the Participant's
            lifetime, or by the person to whom the Participant's rights shall
            pass by will or the laws of descent and distribution.

                  (B) Except as provided in (C) below, no Award and no right
            under any such Award may be assigned, alienated, pledged, attached,
            sold or otherwise transferred or encumbered by a Participant and any
            such purported assignment, alienation, pledge, attachment, sale,
            transfer or encumbrance shall be void and unenforceable against the
            Company or any Affiliate.

                  (C) To the extent specifically provided by the Committee with
            respect to an Option grant, an Option may be transferred by a
            Participant without consideration to immediate family members or
            related family trusts, limited partnerships or similar entities or
            on such terms and conditions as the Committee may from time to time
            establish. In addition, Awards may be transferred by will and the
            laws of descent and distribution.

            (iii) Term of Awards. The term of each Award shall be for such
      period as may be determined by the Committee.

            (iv) Unit Certificates. All certificates for Units or other
      securities of the Partnership delivered under the Plan pursuant to any
      Award or the exercise thereof shall be subject to such stop transfer
      orders and other restrictions as the Committee may deem advisable under
      the Plan or the rules, regulations, and other requirements of the SEC, any
      stock exchange upon which such Units or other securities are then listed,
      and any applicable

                                      -6-
<PAGE>

      federal or state laws, and the Committee may cause a legend or legends to
      be put on any such certificates to make appropriate reference to such
      restrictions.

            (v) Consideration for Grants. Awards may be granted for such
      consideration, including services, as the Committee determines.

            (vi) Delivery of Units or other Securities and Payment by
      Participant of Consideration. Notwithstanding anything in the Plan or any
      grant agreement to the contrary, delivery of Units pursuant to the
      exercise or vesting of an Award may be deferred for any period during
      which, in the good faith determination of the Committee, the Company is
      not reasonably able to obtain Units to deliver pursuant to such Award
      without violating the rules or regulations of any applicable law or
      securities exchange. No Units or other securities shall be delivered
      pursuant to any Award until payment in full of any amount required to be
      paid pursuant to the Plan or the applicable Award grant agreement
      (including, without limitation, any exercise price or tax withholding) is
      received by the Company. Such payment may be made by such method or
      methods and in such form or forms as the Committee shall determine,
      including, without limitation, cash, cashless-broker exercises with
      simultaneous sale, or any combination thereof; provided that the combined
      value, as determined by the Committee, of all cash and cash equivalents
      and the Fair Market Value of any such Units or other property so tendered
      to the Company, as of the date of such tender, is at least equal to the
      full amount required to be paid to the Company pursuant to the Plan or the
      applicable Award Agreement.

            SECTION 6A. Change in Control.

      (a) Awards Granted Prior to February 3, 2003. Upon a Change in Control or
such period prior thereto as may be established by the Committee, all Awards
granted prior to February 3, 2003 shall automatically vest and become payable or
exercisable, as the case may be, in full and all Restricted Periods shall
terminate and all performance criteria, if any, shall be deemed to have been
achieved at the maximum level with respect to such Awards.

      (b) Awards Granted On or After February 3, 2003. If, within two (2) years
following a Change in Control, a Participant has a Termination of Affiliation
(excluding any transfer to an Affiliate of the Company) voluntarily for Good
Reason, or involuntarily (other than due to Cause) Awards granted on or after
February 3, 2003, shall automatically vest and become payable or exercisable, as
the case may be, in full, and all Restricted Periods shall terminate and all
performance criteria, if any, shall be deemed to have been achieved at the
maximum level with respect to such Awards. To the extent an Option granted on or
after February 3, 2003, is not exercised upon a Change in Control, the Committee
may, in its discretion, cancel such Award without payment or provide for a
replacement grant with respect to such property and on such terms as it deems
appropriate.

      principal securities exchange on which the Units are traded and subject to
      Section 7(b) below, the Board or the Committee may amend, alter, suspend,
      discontinue, or terminate the Plan in any manner, including increasing the
      number of Units available for Awards under the Plan, without the consent
      of any partner, Participant, other holder or beneficiary of an Award, or
      other Person; provided, however, that no amendment to the Plan may be made
      without the approval of a Unit Majority (as defined in the Partnership
      Agreement) that would permit DERs to be granted prior to the end of the
      Subordination Period (as defined in the Partnership Agreement).

            (b) Amendments to Awards. Subject to Section 7(a), the Committee may
      waive any conditions or rights under, amend any terms of, or alter any
      Award theretofore granted, provided no change, other than pursuant to
      Section 7(c), in any Award shall materially reduce the benefit to
      Participant without the consent of such Participant.

            (c) Adjustment of Awards Upon the Occurrence of Certain Unusual or
      Nonrecurring Events. The Committee is hereby authorized to make
      adjustments in the terms and conditions of, and the criteria included in,
      Awards in recognition of unusual or nonrecurring events (including,
      without limitation, the events described in Section 4(c) of the Plan)
      affecting the Partnership or the financial statements of the Partnership,
      or of changes in applicable laws, regulations, or accounting principles,
      whenever the Committee determines that such adjustments are appropriate in
      order to prevent dilution or enlargement of the benefits or potential
      benefits intended to be made available under the Plan.

      SECTION 8. General Provisions.

      (a) No Rights to Award. No Person shall have any claim to be granted any
Award under the Plan, and there is no obligation for uniformity of treatment of
Participants. The terms and conditions of Awards need not be the same with
respect to each recipient.

      (b) Withholding. The Company or any Affiliate is authorized to withhold
from any Award, from any payment due or transfer made under any Award or from
any compensation or other amount owing to a Participant the amount (in cash,
Units, other securities, Units that would otherwise be issued pursuant to such
Award or other property) of any applicable taxes payable in respect of the grant
of an Award, its exercise, the lapse of restrictions thereon, or any payment or
transfer under an Award or under the Plan and to take such other action as may
be necessary in the opinion of the Company to satisfy its withholding
obligations for the payment of such taxes. In no event shall the withholding for
taxes exceed that which is necessary to satisfy the employer's minimum
withholding requirements.

      (c) No Right to Employment. The grant of an Award shall not be construed
as giving a Participant the right to be retained in the employ of the Company or
any Affiliate or to remain on the Board, as applicable. Further, the Company or
an Affiliate may at any time dismiss a Participant from employment, free from
any liability or any claim under the Plan, unless otherwise expressly provided
in the Plan or in any Award agreement.

      (d) Governing Law. The validity, construction, and effect of the Plan and
any rules and regulations relating to the Plan shall be determined in accordance
with the laws of the State of Delaware law without regard to its conflict of
laws principles.

      (e) Severability. If any provision of the Plan or any award is or becomes
or is deemed to be invalid, illegal, or unenforceable in any jurisdiction or as
to any Person or Award, or would disqualify the Plan or any award under any law
deemed applicable by the Compensation Committee, such provision shall be
construed or deemed amended to conform to the applicable laws, or if it

                                      -10-
<PAGE>

cannot be construed or deemed amended without, in the determination of the
Compensation Committee, materially altering the intent of the Plan or the Award,
such provision shall be stricken as to such jurisdiction, person or award and
the remainder of the Plan and any such Award shall remain in full force and
effect.

      (f) Other Laws. The Committee may refuse to issue or transfer any Units or
other consideration under an Award if, in its sole discretion, it determines
that the issuance or transfer or such Units or such other consideration might
violate any applicable law or regulation, the rules of the principal securities
exchange on which the Units are then traded, or entitle the Partnership or an
Affiliate to recover the same under Section 16(b) of the Exchange Act, and any
payment tendered to the Company by a Participant, other holder or beneficiary in
connection with the exercise of such Award shall be promptly refunded to the
relevant Participant, holder or beneficiary.

      (g) No Trust or Fund Created. Neither the Plan nor any award shall create
or be construed to create a trust or separate fund of any kind or a fiduciary
relationship between the Company or any participating Affiliate and a
Participant or any other Person. To the extent that any Person acquires a right
to receive payments from the Company or any participating Affiliate pursuant to
an award, such right shall be no greater than the right of any general unsecured
creditor of the Company or any participating Affiliate.

      (h) No Fractional Units. No fractional Units shall be issued or delivered
pursuant to the Plan or any Award, and the Committee shall determine whether
cash, other securities, or other property shall be paid or transferred in lieu
of any fractional Units or whether such fractional Units or any rights thereto
shall be canceled, terminated, or otherwise eliminated.

      (i) Headings. Headings are given to the Sections and subsections of the
Plan solely as a convenience to facilitate reference. Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.

      (j) Facility Payment. Any amounts payable hereunder to any person under
legal disability or who, in the judgment of the Committee, is unable to properly
manage his financial affairs, may be paid to the legal representative of such
person, or may be applied for the benefit of such person in any manner which the
Committee may select, and the Company shall be relieved of any further liability
for payment of such amounts.

      (k) Gender and Number. Words in the masculine gender shall include the
feminine gender, the plural shall include the singular and the singular shall
include the plural.

      SECTION 9. Term of the Plan.

      The Plan shall be effective on the date of its approval by the Board and
shall continue until the date terminated by the Board or Units are no longer
available for the payment of Awards under the Plan, whichever occurs first.
However, unless otherwise expressly provided in the Plan or in an applicable
Award Agreement, any Award granted prior to such termination, and the authority
of the

                                      -11-
<PAGE>

Board or the Committee to amend, alter, adjust, suspend, discontinue, or
terminate any such Award or to waive any conditions or rights under such Award,
shall extend beyond such termination date.

later than 11:00 a.m., New York time, (i) three Business Days prior to the
requested date of any Borrowing of, conversion to or continuation of Eurodollar
Rate Loans, (ii) one Business Day prior to the conversion of Eurodollar Rate
Loans to Base Rate Loans, and (iii) on the requested date of any Borrowing of
Base Rate Loans. Each such telephonic notice must be confirmed promptly by
delivery to the Administrative Agent of a written Borrowing Notice,
appropriately completed and signed by an authorized officer of the Borrower.
Each Borrowing of, conversion to or continuation of Eurodollar Rate Loans shall
be in a principal amount of $500,000 or a whole multiple of $500,000 in excess
thereof. Each Borrowing of or conversion to Base Rate Loans shall be in a
principal amount of $500,000 or a whole multiple of $100,000 in excess thereof.
Each Borrowing Notice (whether telephonic or written) shall specify (i) whether
the Borrower is requesting a Borrowing, a conversion of Loans from one Type to
the other, or a continuation of Loans as the same Type, (ii) the requested date
of the Borrowing, conversion or continuation, as the case may be (which shall be
a Business Day), (iii) the principal amount of Loans to be borrowed, converted
or continued, (iv) the Type of Loans to be borrowed or to which existing Loans
are to be converted, and (v) if applicable, the duration of the Interest Period
with respect thereto. If the Borrowers fail to specify a Type of Loan in a
Borrowing Notice or if the Borrowers fail to give a timely notice requesting a
conversion or continuation, then the applicable Loans shall be made or continued
as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate
Loans shall be effective as of the last day of the Interest Period then in
effect with respect to the applicable Eurodollar Rate Loans. If the Borrowers
request a Borrowing of, conversion to, or continuation of Eurodollar Rate Loans
in any such Borrowing Notice, but fails to specify an Interest Period, it will
be deemed to have specified an Interest Period of one month.

      (b) Following receipt of a Borrowing Notice, the Administrative Agent
shall promptly notify each Lender of its Pro Rata Share of the Loans, and if no
timely notice of a conversion or continuation is provided by the Borrower, the
Administrative Agent shall notify each Lender of the details of any automatic
conversion to Base Rate Loans described in the preceding subsection. In the case
of a Borrowing, each Lender shall make the amount of its Loan available to the
Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than 1:00 p.m., New York time, on the Business Day
specified in the applicable Borrowing Notice. Upon satisfaction of the
applicable conditions set forth in SECTIONS 4.01 AND 4.02, the Administrative
Agent shall make all funds so received available to the Borrower in like funds
as received by the Administrative Agent either by (i) crediting the account of
the Borrower on the books of Bank of America with the amount of such funds or
(ii) wire transfer of such funds, in each case in accordance with instructions
provided to the Administrative Agent by the Borrower.

      (c) Except as otherwise provided herein, a Eurodollar Rate Loan may be
continued or converted only on the last day of the Interest Period for such
Eurodollar Rate Loan. During the existence of a Default or Event of Default, no
Loans may be requested as, converted to or continued as Eurodollar Rate Loans
without the consent of the Required Lenders, and the Required Lenders may demand
that any or all of the then outstanding Eurodollar Rate Loans be converted
immediately to Base Rate Loans.

      (d) The Administrative Agent shall promptly notify the Borrowers and the
Lenders of the interest rate applicable to any Eurodollar Rate Loan upon
determination of such interest rate. The determination of the Eurodollar Rate by
the Administrative Agent shall be conclusive in the absence of manifest error.

      (e) After giving effect to all Borrowings, all conversions of Loans from
one Type to the other, and all continuations of Loans as the same Type, there
shall not be more than ten (10) Interest Periods in effect at any given time
with respect to Loans.

      2.03 PREPAYMENTS.

      (a) Optional Prepayments. The Borrowers may, upon notice to the
Administrative Agent, at any time or from time to time voluntarily prepay in
whole or in part the Loans without premium or penalty; provided that (i) such
notice must be received by the Administrative Agent not later than 11:00 a.m.,
New York time, (A) three Business Days prior to any date of prepayment of
Eurodollar Rate Loans, and (B) on the date of prepayment of Base Rate Loans;
(ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of
$500,000 or a whole multiple of $500,000 in excess thereof; and (iii) any
prepayment of Base Rate Loans shall be in a principal amount of $500,000 or a
whole multiple of $100,000 in excess thereof. Each such notice shall specify the
date and amount of such prepayment and the Type(s) of Loans to be prepaid. The
Administrative Agent will promptly notify each Lender of its receipt of each
such notice, and of such Lender's Pro Rata Share of such prepayment. If such
notice is given by the Borrower, the Borrower shall make such prepayment and the
payment amount specified in such notice shall be due and payable on the date
specified therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied
by all accrued interest thereon, together with any additional amounts required
pursuant to SECTION 3.05. Each such prepayment shall be applied to the Loans of
the Lenders in accordance with their respective Pro Rata Shares.

      (b) Mandatory Prepayments from Net Cash Proceeds. Until such time as the
Outstanding Amount has been repaid in full, the Outstanding Amount shall be
permanently prepaid in the amounts and upon the occurrence of any of the
following events:

                                       18
<PAGE>

            (i) Debt Issuance. In the event of any Debt Issuance by the
      Borrowers or any of their Subsidiaries (other than Debt Issuance by OLP
      No. 1 under the OLP No. 1 Credit Agreement and any additional Debt
      Issuance by OLP No. 1 to the extent permitted by the OLP No. 1 Credit
      Agreement), then concurrently with such Debt Issuance, the Loans shall be
      prepaid by an amount equal to 100% of the Net Cash Proceeds of such Debt
      Issuance.

            (ii) Dispositions. If any portion of the Net Cash Proceeds realized
      by the Borrowers or any of their Subsidiaries (other than OLP No. 1), from
      any Disposition (including any deferred purchase price therefor and any
      Net Cash Proceeds of any Disposition) has not been reinvested in assets
      used in the Present and Related Businesses of Williams LLC or its
      Subsidiaries within ninety (90) days from the receipt by Borrowers or such
      Subsidiary of such Net Cash Proceeds (including receipt of any deferred
      payments for any such Disposition or portion thereof, if and when
      received), then on the day following the ninetieth day after receipt of
      such Net Cash Proceeds, the Loans shall be prepaid by an amount equal to
      100% of all such Net Cash Proceeds not so reinvested.

            (iii) Equity Issuance. In the event of any Equity Issuance by the
      MLP or any of its Subsidiaries (other than (A) equity interests issued to
      the MLP or a Wholly-Owned Subsidiary of the MLP, and (B) non-registered
      Class B units issued by the MLP in connection with the contribution of the
      Contributed Interests), then concurrently with such Equity Issuance, the
      Loans shall be prepaid by an amount equal to 100% of the Net Cash Proceeds
      of such Equity Issuance

      The prepayments under SECTIONS 2.03(b)(i), (ii) and (iii) shall be applied
as a prepayment of the Principal Debt until Principal Debt is paid in full,
unless a Default or Event of Default has occurred and is continuing or would
arise as a result thereof (whereupon the provisions of SECTION 2.12(b) shall
apply). All mandatory prepayments of the Principal Debt shall be allocated Pro
Rata to each Lender.

      (c) Mandatory Prepayments: Interest/Consequential Loss. All prepayments
under this SECTION 2.03 shall be made together with accrued interest to the date
of such prepayment on the principal amount prepaid and any amounts due under
SECTION 3.05.

      2.04 INTENTIONALLY OMITTED.

      2.05 REPAYMENT OF LOANS. The Borrowers shall repay to the Lenders on the
Maturity Date the Principal Debt outstanding on such date.

      2.06 INTEREST.

      (a) Subject to the provisions of subsection (b) below, (i) each Eurodollar
Rate Loan shall bear interest on the outstanding principal amount thereof for
each Interest Period at a rate per annum equal to the Eurodollar Rate for such
Interest Period plus the Applicable Margin and (ii) each Base Rate Loan shall
bear interest on the outstanding principal amount thereof from the applicable
borrowing date at a rate per annum equal to the Base Rate plus the Applicable
Margin.

      (b) While any Event of Default exists or after acceleration, (i) the
Borrowers shall pay interest on the principal amount of all outstanding
Obligations at a fluctuating interest rate per annum at all times equal to the
Default Rate to the fullest extent permitted by applicable Law, and (ii) accrued
and unpaid interest on past due amounts (including interest on past due
interest) shall be due and payable upon demand.

                                       19
<PAGE>

      (c) Interest on each Loan shall be due and payable in arrears on each
Interest Payment Date applicable thereto and at such other times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Debtor Relief Law.

      (d) If the designated rate applicable to any Borrowing exceeds the Maximum
Rate, the rate of interest on such Borrowing shall be limited to the Maximum
Rate, but any subsequent reductions in such designated rate shall not reduce the
rate of interest thereon below the Maximum Rate until the total amount of
interest accrued thereon equals the amount of interest which would have accrued
thereon if such designated rate had at all times been in effect. In the event
that at maturity (stated or by acceleration), or at final payment of the
Outstanding Amount, the total amount of interest paid or accrued is less than
the amount of interest which would have accrued if such designated rates had at
all times been in effect, then, at such time and to the extent permitted by Law,
the Borrower shall pay an amount equal to the difference between (a) the lesser
of the amount of interest which would have accrued if such designated rates had
at all times been in effect and the amount of interest which would have accrued
if the Maximum Rate had at all times been in effect, and (b) the amount of
interest actually paid or accrued on such Outstanding Amount.

      2.07 FEES. On the Closing Date, the Borrowers shall pay to the
Administrative Agent, for the account of the Lenders in accordance with their
respective Pro Rata Shares, the fees in the agreed amounts in accordance with
those certain letter agreements dated of even date herewith (the "FEE LETTERS")
between the Borrowers and the Lenders. Such fees are for the credit facility by
the Lenders under this Agreement and are fully earned on the date paid. The fees
paid to each Lender pursuant to its respective Fee Letter are solely for its own
account and are nonrefundable for any reason whatsoever.

      2.08 COMPUTATION OF INTEREST AND FEES. Computation of interest on Base
Rate Loans shall be calculated on the basis of a year of 365 or 366 days, as the
case may be, and the actual number of days elapsed. Computation of all other
types of interest and all fees shall be calculated on the basis of a year of 360
days and the actual number of days elapsed, which results in a higher yield to
the payee thereof than a method based on a year of 365 or 366 days. Interest
shall accrue on each Loan for the day on which the Loan is made, and shall not
accrue on a Loan, or any portion thereof, for the day on which the Loan or such
portion is paid, provided that any Loan that is repaid on the same day on which
it is made shall bear interest for one day.

      2.09 EVIDENCE OF DEBT. The Loans made by each Lender shall be evidenced by
one or more accounts or records maintained by such Lender and by the
Administrative Agent in the ordinary course of business. The accounts or records
maintained by the Administrative Agent and each Lender shall be conclusive
absent manifest error of the amount of the Loans made by the Lenders to the
Borrowers and the interest and payments thereon. Any failure so to record or any
error in doing so shall not, however, limit or otherwise affect the obligation
of the Borrowers hereunder to pay any amount owing with respect to the Loans. In
the event of any conflict between the accounts and records maintained by any
Lender and the accounts and records of the Administrative Agent in respect of
such matters, the accounts and records of such Lender shall control. Upon the
request of any Lender made through the Administrative Agent, such Lender's Loans
may be evidenced by a Note (with respect to the Principal Debt). Each Lender may
attach schedules to its Note(s) and endorse thereon the date, Type (if
applicable), amount and maturity of the applicable Loans and payments with
respect thereto.

                                       20

      2.10 PAYMENTS GENERALLY.

      (a) All payments to be made by the Borrowers shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Borrowers
hereunder shall be made to the Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Administrative Agent's
Office in Dollars and in immediately available funds not later than 12:00 noon,
New York time, on the date specified herein. The Administrative Agent will
promptly distribute to each Lender its Pro Rata Share (or other applicable share
as provided herein) of such payment in like funds as received by wire transfer
to such Lender's Lending Office. All payments received by the Administrative
Agent after 12:00 noon, New York time, shall be deemed received on the next
succeeding Business Day and any applicable interest or fee shall continue to
accrue.

      (b) Subject to the definition of "Interest Period," if any payment to be
made by the Borrower shall come due on a day other than a Business Day, payment
shall be made on the next following Business Day, and such extension of time
shall be reflected in computing interest or fees, as the case may be.

      (c) If at any time insufficient funds are received by and available to the
Administrative Agent to pay fully the Obligations, such funds shall be applied
(i) first, toward costs and expenses (including Attorney Costs and amounts
payable under ARTICLE III) incurred by the Administrative Agent and each Lender,
(ii) second, toward repayment of interest and fees then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, (iii) third, toward repayment of principal
then due hereunder, ratably among the parties entitled thereto in accordance
with the amounts of principal then due to such parties, and (iv) fourth, toward
the repayment of all other Obligations.

      (d) Unless the Borrowers or any Lender has notified the Administrative
Agent prior to the date any payment is required to be made by it to the
Administrative Agent hereunder, that the Borrowers or such Lender, as the case
may be, will not make such payment, the Administrative Agent may assume that the
Borrowers or such Lender, as the case may be, has timely made such payment and
may (but shall not be so required to), in reliance thereon, make available a
corresponding amount to the Person entitled thereto. If and to the extent that
such payment was not in fact made to the Administrative Agent in immediately
available funds, then:

            (i) if the Borrowers failed to make such payment, each Lender shall
      forthwith on demand repay to the Administrative Agent the portion of such
      assumed payment that was made available to such Lender in immediately
      available funds, together with interest thereon in respect of each day
      from and including the date such amount was made available by the
      Administrative Agent to such Lender to the date such amount is repaid to
      the Administrative Agent in immediately available funds, at the Federal
      Funds Rate from time to time in effect; and

            (ii) if any Lender failed to make such payment, such Lender shall
      forthwith on demand pay to the Administrative Agent the amount thereof in
      immediately available funds, together with interest thereon for the period
      from the date such amount was made available by the Administrative Agent
      to the Borrowers to the date such amount is recovered by the
      Administrative Agent (the "COMPENSATION PERIOD") at a rate per annum equal
      to the Federal Funds Rate from time to time in effect. If such Lender pays
      such amount to the Administrative Agent, then such amount shall constitute
      such Lender's Loan, included in the applicable Borrowing. If such Lender
      does not pay such amount forthwith upon the Administrative Agent's

                                       21
<PAGE>

      demand therefor, the Administrative Agent may make a demand therefor upon
      the Borrowers, and the Borrowers shall pay such amount to the
      Administrative Agent, together with interest thereon for the Compensation
      Period at a rate per annum equal to the rate of interest applicable to the
      applicable Borrowing. Nothing herein shall be deemed to relieve any Lender
      from its obligation to fulfill its Commitment or to prejudice any rights
      which the Administrative Agent or the Borrowers may have against any
      Lender as a result of any default by such Lender hereunder.

      A notice of the Administrative Agent to any Lender with respect to any
amount owing under this subsection (d) shall be conclusive, absent manifest
error.

      (e) If any Lender makes available to the Administrative Agent funds for
any Loan to be made by such Lender as provided in the foregoing provisions of
this ARTICLE II, and the conditions to the applicable Borrowing set forth in
ARTICLE IV are not satisfied or waived in accordance with the terms hereof, the
Administrative Agent shall return such funds (in like funds as received from
such Lender) to such Lender, without interest.

      (f) The obligations of the Lenders hereunder to make Loans are several and
not joint. The failure of any Lender to make any Loan on any date required
hereunder shall not relieve any other Lender of its corresponding obligation to
do so on such date, and no Lender shall be responsible for the failure of any
other Lender to so make its Loan or purchase its participation.

      (g) Nothing herein shall be deemed to obligate any Lender to obtain the
funds for any Loan in any particular place or manner or to constitute a
representation by any Lender that it has obtained or will obtain the funds for
any Loan in any particular place or manner.

      2.11 SHARING OF PAYMENTS. If, other than as expressly provided elsewhere
herein, any Lender shall obtain on account of the Loans made by it, any payment
(whether voluntary, involuntary, through the exercise of any right of set-off,
or otherwise) in excess of its ratable share (or other share contemplated
hereunder) thereof, such Lender shall immediately (a) notify the Administrative
Agent of such fact, and (b) purchase from the other Lenders such participations
in the Loans made by them, as shall be necessary to cause such purchasing Lender
to share the excess payment in respect of such Loan or such participations, as
the case may be, pro rata with each of them; provided, however, that if all or
any portion of such excess payment is thereafter recovered from the purchasing
Lender, such purchase shall to that extent be rescinded and each other Lender
shall repay to the purchasing Lender the purchase price paid therefor, together
with an amount equal to such paying Lender's ratable share (according to the
proportion of (i) the amount of such paying Lender's required repayment to (ii)
the total amount so recovered from the purchasing Lender) of any interest or
other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to SECTION 10.09) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or
repayments. Each Lender that purchases a participation pursuant to this Section
shall from and after such purchase have the right to give all notices, requests,
demands, directions and other communications under this Agreement with respect
to the portion of the Obligations purchased to the same extent as though the
purchasing Lender were the original owner of the Obligations purchased.

                                       22

      2.12 ORDER OF APPLICATION.

      (a) No Default. If no Default or Event of Default exists and if no order
of application is otherwise specified in the Loan Documents, payments and
prepayments of the Obligations shall be applied first to fees, second to accrued
interest then due and payable on the Outstanding Amount, and then to the
remaining Obligations in the order and manner as the Borrowers may direct.

      (b) Default. If a Default or Event of Default exists (or if the Borrowers
fail to give directions as permitted under SECTION 2.12(a)), any payment or
prepayment (including proceeds from the exercise of any Rights) shall be applied
to the Obligations in the following order: (i) to the payment of enforcement
expenses incurred by the Administrative Agent, including Attorney Costs; (ii) to
the ratable payment of all other fees, expenses, and indemnities for which the
Administrative Agent or Lenders have not been paid or reimbursed in accordance
with the Loan Documents (as used in this SECTION 2.12(b)(ii), a "RATABLE
PAYMENT" for any Lender or the Administrative Agent shall be, on any date of
determination, that proportion which the portion of the total fees, expenses,
and indemnities owed to such Lender or the Administrative Agent bears to the
total aggregate fees and indemnities owed to all Lenders and the Administrative
Agent on such date of determination); (iii) to the ratable payment of accrued
and unpaid interest on the Outstanding Amount (as used in this SECTION
2.12(b)(iii), "RATABLE PAYMENT" means, for any Lender, on any date of
determination, that proportion which the accrued and unpaid interest on the
Outstanding Amount owed to such Lender bears to the total accrued and unpaid
interest on the Outstanding Amount owed to all Lenders); (iv) to the ratable
payment of the Outstanding Amount (as used in this SECTION 2.12(b)(iv), "RATABLE
PAYMENT" means for any Lender, on any date of determination, that proportion
which the Outstanding Amount owed to such Lender bears to the Outstanding Amount
owed to all Lenders); and (v) to the payment of the remaining Obligations, if
any, in the order and manner Required Lenders deem appropriate.

      Subject to the provisions of ARTICLE IX and provided that Administrative
Agent shall not in any event be bound to inquire into or to determine the
validity, scope, or priority of any interest or entitlement of any Lender and
may suspend all payments or seek appropriate relief (including, without
limitation, instructions from Required Lenders or an action in the nature of
interpleader) in the event of any doubt or dispute as to any apportionment or
distribution contemplated hereby, Administrative Agent shall promptly distribute
such amounts to each Lender in accordance with the Agreement and the related
Loan Documents.

      2.13 OBLIGATIONS JOINT AND SEVERAL. All Obligations (including indemnity
Obligations) of the Borrowers under this Agreement and the Notes shall
constitute joint and several obligations of the Borrowers. Each Borrower
expressly represents and acknowledges that it is part of a single business
enterprise formed to own and operate the Pipeline Assets with the other Borrower
and that any Loans by the Lenders to the other Borrower hereunder will be of
direct and indirect interest, benefit and advantage of both of the Borrowers.
Each Borrower acknowledges that any Borrowing Notice, Conversion/Continuation
Notice or other notice given by either of the Borrowers to the Administrative
Agent or any Lender shall bind both of the Borrowers, and that any notice given
by the Administrative Agent or any Lender to either of the Borrowers shall be
effective with respect to all Borrowers. Each Borrower acknowledges and agrees
that each Borrower shall be liable not merely as a surety but as a co-debtor, on
a joint and several basis, for all of the Loans, regardless of which Borrower
may actually have received the proceeds of any of the Loans or the amount of
such Loans received or the manner in which the Administrative Agent or any
Lender accounts for such Loans on its books and records, and further
acknowledges and agrees that Loans to either Borrower inure to the mutual
benefit of both Borrowers and that the Administrative Agent and the Lenders are
relying on the joint and several liability of the Borrowers in extending the
Loans hereunder. Each Borrower hereby waives, to the fullest extent

                                       23
<PAGE>

permitted by applicable Law, all surety defenses, whether at law or in equity;
without limitation of the foregoing, each Borrower assents to, and waives notice
of, any extension or postponement of the time for the payment or performance of
all or any part of the Obligations, the acceptance of any partial payment
thereon, any waiver, consent or other action or acquiescence by the
Administrative Agent or the Lenders at any time or times in respect of any
default by any Borrower in the payment or performance of any of the Obligations,
any and all other indulgences whatsoever by the Administrative Agent or the
Lenders in respect of all or any part of the Obligations, and the taking,
addition, substitution or release, in whole or in part, at any time or times, of
any security for all or any part of the Obligations or the addition,
substitution or release, in whole or in part, of any Borrower or any Guarantor
or other Person now or hereafter liable for payment or performance of the
Obligations. Without limiting the generality of the foregoing, each Borrower
assents to any other action or delay in acting or failure to act on the part of
the Administrative Agent or the Lenders, including, without limitation, any
failure strictly or diligently to assert any right or to pursue any remedy or to
comply fully with applicable laws or regulations thereunder which might, but for
the provisions of this SECTION 2.13, afford grounds for terminating, discharging
or relieving such Borrower, in whole or in part, from any of its obligations
under this SECTION 2.13, it being the intention of each Borrower that, so long
as all or any part of the Obligations remains unsatisfied, the obligations of
such Borrower under this SECTION 2.13 shall not be discharged except by payment
or performance and then only to the extent of such payment or performance. A
separate action or actions may be brought and prosecuted against either Borrower
in respect of the Obligations, and it shall not be necessary to join the other
Borrower in any such action or actions, any right to require such joinder being
hereby waived to the fullest permitted by applicable Law. The obligations of
each Borrower under this SECTION 2.13 shall not be diminished or rendered
unenforceable by any unenforceability or invalidity of the Obligations as to the
other Borrower, or by any bankruptcy, insolvency, winding up, reorganization,
arrangement, liquidation, reconstruction or similar proceeding with respect to
any reconstruction or similar proceeding with respect to any Borrower. The joint
and several liability of the Borrowers hereunder shall continue in full force
and effect notwithstanding any absorption, merger, amalgamation or any other
change whatsoever in the name, membership, constitution or place of formation of
any Borrower. Each Borrower shall be entitled to subrogation and contribution
rights from and against the other Borrower to the extent such Borrower is
required to pay to the Administrative Agent or any Lender any principal,
interest or other amount attributable to the Loans advanced hereunder to the
other Borrower or as otherwise available under applicable Law; provided, no
Borrower shall exercise any rights of subrogation or contribution prior to the
indefeasible payment in full in cash of all of the Obligations. The provisions
of this SECTION 2.13 shall remain in effect until all of the Obligations shall
have been indefeasibly paid in full in cash. If at any time, any payment, or any
part thereof, made in respect of all or any part of the Obligations, is
rescinded or must otherwise be restored or returned by the Administrative Agent
or any of the Lenders upon the insolvency, bankruptcy or reorganization of the
Borrowers, or either of them,, or otherwise, the provisions of this SECTION 2.13
will forthwith be reinstated in effect, as though such payment had not been
made.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

      3.01 TAXES.

      (a) Any and all payments by the Borrowers to or for the account of the
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative Agent and each Lender, taxes imposed on or measured by its net
income, and franchise taxes imposed on it (in lieu of net income taxes), by the
jurisdiction (or any political subdivision thereof) under the Laws of

                                       24
<PAGE>

which the Administrative Agent or such Lender, as the case may be, is organized
or maintains its Lending Office (all such non-excluded taxes, duties, levies,
imposts, deductions, assessments, fees, withholdings or similar charges, and
liabilities being hereinafter referred to as "TAXES"). If the Borrower shall be
required by any Laws to deduct any Taxes from or in respect of any sum payable
under any Loan Document to the Administrative Agent or any Lender, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section), each of the Administrative Agent and such Lender receives an
amount equal to the sum it would have received had no such deductions been made,
(ii) the Borrowers shall make such deductions, (iii) the Borrowers shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable Laws, and (iv) within 30 days after the date of such
payment, the Borrowers shall furnish to the Administrative Agent (which shall
forward the same to such Lender) the original or a certified copy of a receipt
evidencing payment thereof.

      (b) In addition, the Borrowers agree to pay any and all present or future
stamp, court or documentary taxes and any other excise or property taxes or
charges or similar levies which arise from any payment made under any Loan
Document or from the execution, delivery, performance, enforcement or
registration of, or otherwise with respect to, any Loan Document (hereinafter
referred to as "OTHER TAXES").

      (c) If the Borrowers shall be required to deduct or pay any Taxes or Other
Taxes from or in respect of any sum payable under any Loan Document to the
Administrative Agent or any Lender, the Borrowers shall also pay to the
Administrative Agent (for the account of such Lender) or to such Lender, at the
time interest is paid, such additional amount that such Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes,
including taxes imposed on or measured by net income) such Lender would have
received if such Taxes or Other Taxes had not been imposed.

      (d) The Borrowers agree to indemnify the Administrative Agent and each
Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by the Administrative Agent and such Lender, (ii) amounts
payable under SECTION 3.01(c) and (iii) any liability (including penalties,
interest and expenses) arising therefrom or with respect thereto. Payment under
this subsection (d) shall be made within 30 days after the date the Lender or
the Administrative Agent makes a demand therefor.

      3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans, or materially restricts the authority of such Lender to
purchase or sell, or to take deposits of, Dollars in the applicable offshore
Dollar market, or to determine or charge interest rates based upon the
Eurodollar Rate, then, on notice thereof by such Lender to the Borrower through
the Administrative Agent, any obligation of such Lender to make or continue
Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans
shall be suspended until such Lender notifies the Administrative Agent and the
Borrower that the circumstances giving rise to such determination no longer
exist. Upon receipt of such notice, the Borrowers shall, upon demand from such
Lender (with a copy to the Administrative Agent), prepay or, if applicable,
convert all Eurodollar Rate Loans of such Lender to Base Rate Loans, either on
the last day of the Interest Period thereof, if such Lender may lawfully
continue to maintain such Eurodollar Rate Loans to such day, or immediately, if
such Lender may not lawfully continue to maintain such Eurodollar Rate Loans.
Upon any such prepayment or conversion, the Borrowers shall also pay interest on
the amount so prepaid or converted. Each Lender agrees to designate a different
Lending Office if such designation will avoid the need for such notice and will
not, in the reasonable judgment of such Lender, otherwise be materially
disadvantageous to such Lender.

                                       25
<PAGE>

      3.03 INABILITY TO DETERMINE RATES. If the Administrative Agent determines
in connection with any request for a Eurodollar Rate Loan or a conversion to or
continuation thereof that (a) Dollar deposits are not being offered to banks in
the applicable offshore Dollar market for the applicable amount and Interest
Period of such Eurodollar Rate Loan, or adequate and reasonable means do not
exist for determining the Eurodollar Rate for such Eurodollar Rate Loan, or (b)
if the Required Lenders determine and notify the Administrative Agent that the
Eurodollar Rate for such Eurodollar Rate Loan does not adequately and fairly
reflect the cost to the Lenders of funding such Eurodollar Rate Loan, then the
Administrative Agent will promptly notify the Borrowers and all Lenders.
Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate
Loans shall be suspended until the Administrative Agent revokes such notice.
Upon receipt of such notice, the Borrowers may revoke any pending request for a
Borrowing, conversion or continuation of Eurodollar Rate Loans or, failing that,
will be deemed to have converted such request into a request for a Borrowing of
Base Rate Loans in the amount specified therein.

      3.04 INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY; RESERVES ON
EURODOLLAR RATE LOANS.

      (a) If any Lender determines that as a result of the introduction of or
any change in or in the interpretation of any Law, or such Lender's compliance
therewith, there shall be any increase in the cost to such Lender of agreeing to
make or making, funding or maintaining Eurodollar Rate Loans, or a reduction in
the amount received or receivable by such Lender in connection with any of the
foregoing (excluding for purposes of this subsection (a) any such increased
costs or reduction in amount resulting from (i) Taxes or Other Taxes (as to
which SECTION 3.01 shall govern), (ii) changes in the basis of taxation of
overall net income or overall gross income by the United States or any foreign
jurisdiction or any political subdivision of either thereof under the Laws of
which such Lender is organized or has its Lending Office, and (iii) reserve
requirements contemplated by SECTION 3.04(c) utilized, as to Eurodollar Rate
Loans, in the determination of the Eurodollar Rate), then from time to time upon
demand of such Lender (with a copy of such demand to the Administrative Agent),
the Borrowers shall pay to such Lender such additional amounts as will
compensate such Lender for such increased cost or reduction. No Lender shall
have the right to recover such additional amounts for any period more than 90
days prior to the date such Lender notified the Borrowers thereof.

      (b) If any Lender determines that the introduction of any Law regarding
capital adequacy or any change therein or in the interpretation thereof, or
compliance by such Lender (or its Lending Office) therewith, has the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of such Lender's obligations hereunder
(taking into consideration its policies with respect to capital adequacy and
such Lender's desired return on capital), then from time to time upon demand of
such Lender (with a copy of such demand to the Administrative Agent), the
Borrowers shall pay to such Lender such additional amounts as will compensate
such Lender for such reduction. No Lender shall have the right to recover such
additional amounts for any period more than 90 days prior to the date such
Lender notified the Borrowers thereof.

      (c) The Borrowers shall pay to each Lender, as long as such Lender shall
be required under regulations of the Board to maintain reserves with respect to
liabilities or assets consisting of or including Eurocurrency funds or deposits
(currently known as "Eurocurrency liabilities"), additional costs on the unpaid
principal amount of each Eurodollar Rate Loan equal to the actual costs of such
reserves allocated to such Loan by such Lender (as determined by such Lender in
good faith, which determination shall be conclusive), which shall be due and
payable on each date on which interest is payable on such Loan, provided the
Borrowers shall have received at least 15 days' prior notice (with a copy to the
Administrative Agent) of such additional interest from such Lender. If a Lender
fails to give

                                       26
<PAGE>

notice 15 days prior to the relevant Interest Payment Date, such additional
interest shall be due and payable 15 days from receipt of such notice.

      3.05 FUNDING LOSSES. Upon demand of any Lender (with a copy to the
Administrative Agent) from time to time, the Borrowers shall promptly compensate
such Lender for and hold such Lender harmless from any loss, cost or expense
incurred by it as a result of:

      (a) any continuation, conversion, payment or prepayment of any Loan other
than a Base Rate Loan on a day other than the last day of the Interest Period
for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise); or

      (b) any failure by the Borrowers (for a reason other than the failure of
such Lender to make a Loan) to prepay, borrow, continue or convert any Loan
other than a Base Rate Loan on the date or in the amount notified by the
Borrower;

including any loss of anticipated profits and any loss or expense arising from
the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.
The Borrowers shall also pay any customary administrative fees charged by such
Lender in connection with the foregoing.

      For purposes of calculating amounts payable by the Borrower to the Lenders
under this SECTION 3.05, each Lender shall be deemed to have funded each
Eurodollar Rate Loan made by it at the Eurodollar Rate for such Loan by a
matching deposit or other borrowing in the applicable offshore Dollar interbank
market for a comparable amount and for a comparable period, whether or not such
Eurodollar Rate Loan was in fact so funded.

      3.06 MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION. A certificate of
the Administrative Agent or any Lender claiming compensation under this ARTICLE
III and setting forth the additional amount or amounts to be paid to it
hereunder shall be conclusive in the absence of manifest error. In determining
such amount, the Administrative Agent or such Lender may use any reasonable
averaging and attribution methods.

      3.07 SURVIVAL. All of the Borrowers' obligations under this ARTICLE III
shall survive termination of the Commitments and payment in full of all the
other Obligations.

                                  ARTICLE IV.

                                   ARTICLE V.

Subsidiaries have good and marketable title to, or valid leasehold interests in,

      (a) Each Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code and other federal or state Laws except
to the extent that noncompliance could not reasonably be expected to have a
Material Adverse Effect. Each Plan that is intended to qualify under Section
401(a) of the Code has received a favorable determination letter from the IRS or
an application for such a letter is currently being processed by the IRS with
respect thereto and, to the best knowledge of the Borrowers, nothing has
occurred which would prevent, or cause the loss of, such qualification. The
Borrowers and each ERISA Affiliate have made all required contributions to each
Plan subject to Section 412 of the Code, and no application for a funding waiver
or an extension of any amortization period pursuant to Section 412 of the Code
has been made with respect to any Plan.

      (b) There are no pending or, to the best knowledge of the Borrowers,

any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
under Title IV of ERISA with respect to any Pension Plan (other than premiums
due and not delinquent under Section 4007 of ERISA) which could reasonably be
expected to result in a Material Adverse Effect; (iv) neither the Borrower nor
any ERISA Affiliate has incurred, or reasonably expects to incur, any liability
(and no event has occurred which, with the giving of notice under Section 4219
of ERISA, would result in such liability) under Sections 4201 or 4243 of ERISA
with respect to a Multiemployer Plan which could reasonably be expected to
result in a Material Adverse Effect; and (v) neither the Borrower nor any ERISA
Affiliate has engaged in a transaction that could be subject to Sections 4069 or
4212(c) of ERISA.

to any limitation on a sale, pledge, or other restrictions hereunder.

      (b) No Loan Party, no Person controlling any Loan Party, or any Subsidiary
of any Loan Party (i) is a "holding company," or a "subsidiary company" of a
"holding company," or an "affiliate" of a "holding company" or of a "subsidiary
company" of a "holding company," within the meaning of the Public Utility
Holding Company Act of 1935, or (ii) is or is required to be registered as an
"investment company" under the Investment Company Act of 1940.

      5.15 DISCLOSURE. No statement, information, report, representation, or
warranty made by any Loan Party in any Loan Document or furnished to the
Administrative Agent or any Lender by or on behalf of any Loan Party in
connection with any Loan Document contains any untrue statement of a material
fact or omits any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

      5.16 LABOR MATTERS. To the Borrowers' knowledge, there are no pending or
threatened strikes, labor disputes, slowdowns, walkouts, or other concerted
interruptions of operations by the employees of any Loan Party or any of its
Subsidiaries that could reasonably be expected to have a Material Adverse
Effect. Hours worked by and payment made to employees of Loan Parties and their
Subsidiaries have not been in violation of the Fair Labor Standards Act of 1938
or any other applicable Law dealing with such matters, other than any such
violations, individually or collectively, which could not reasonably be expected
to have a Material Adverse Effect. All payments due from any Loan Party or any
of its Subsidiaries on account of employee health and welfare insurance have
been paid or accrued as a liability on its books, other than any such
nonpayments which could not, individually or collectively, reasonably be
expected to have a Material Adverse Effect.

      5.17 COMPLIANCE WITH LAWS. No Loan Party or any of its Subsidiaries are in
violation of any Laws, other than such violations which could not, individually
or collectively, reasonably be expected to have a Material Adverse Effect. No
Loan Party has received notice alleging any noncompliance with any Laws, except
for such noncompliance which no longer exists, or which noncompliance could not
reasonably be expected to have a Material Adverse Effect.

      5.18 SOLVENCY. At the time of the Borrowing hereunder, each Loan Party is
and, after giving effect to the Borrowing and the transactions contemplated by
this Agreement, and to the transactions applicable to the Loan Parties
contemplated by the Contribution Agreement, will be solvent. As used herein,
"solvent" means, as to a Person, that (i) the aggregate fair market value of
such Person's assets exceeds such Person's debts, (ii) such Person has
sufficient cash flow to enable it to pay its debts as they mature, and (iii)
such Person does not have unreasonably small capital to engage in such Person's
businesses; and "debt" means liability on a claim (whether liquidated or
unliquidated, fixed or contingent, matured or unmatured, disputed or undisputed,
legal or equitable, secured or unsecured, or otherwise) and shall include the
Obligations. The representation and warranty as to solvency has been determined
on a stand-alone basis for each Loan Party and not on a consolidated basis.

      5.19 FAIRNESS OPINIONS. The Conflicts Committee of the General Partner has
received an opinion (the "FAIRNESS OPINION") to the effect that the
consideration (as defined in the Fairness Opinion) to be paid by the MLP
pursuant to the Contribution Agreement is fair, from a financial point of view,
to the MLP. Williams Energy Services, LLC, as seller under the Contribution
Agreement, has received an opinion (the "SELLER FAIRNESS OPINION") to the effect
that the consideration (as defined in the Seller Fairness Opinion) to be
received by the Seller pursuant to the Contribution Agreement is fair, from a
financial point of view, to the Seller.

                                   ARTICLE IX.
                              ADMINISTRATIVE AGENT

      9.01 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT. Each Lender
hereby irrevocably (subject to Section 9.09) appoints, designates and authorizes
the Administrative Agent to take such action on its behalf under the provisions
of this Agreement and each other Loan Document and to exercise such powers and
perform such duties as are expressly delegated to it by the terms of this

                                       43
<PAGE>

Agreement or any other Loan Document, together with such powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
contained elsewhere herein or in any other Loan Document, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein, nor shall the Administrative Agent have or be deemed to have any
fiduciary relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" herein and in the other Loan Documents with
reference to the Administrative Agent is not intended to connote any fiduciary
or other implied (or express) obligations arising under agency doctrine of any
applicable law. Instead, such term is used merely as a matter of market custom,
and is intended to create or reflect only an administrative relationship between
independent contracting parties.

      9.02 DELEGATION OF DUTIES. The Administrative Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,
employees or attorneys-in-fact and shall be entitled to advice of counsel and
other consultants or experts concerning all matters pertaining to such duties.
The Administrative Agent shall not be responsible for the negligence or
misconduct of any agent or attorney-in-fact that it selects in the absence of
gross negligence or willful misconduct.

      9.03 LIABILITY OF ADMINISTRATIVE AGENT. No Agent-Related Person shall (a)
be liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement or any other Loan Document or the transactions
contemplated hereby (except for its own gross negligence or willful misconduct
in connection with its duties expressly set forth herein), or (b) be responsible
in any manner to any Lender or participant for any recital, statement,
representation or warranty made by any Loan Party or any officer thereof,
contained herein or in any other Loan Document, or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, this Agreement or any other
Loan Document, or the validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document, or for any failure of
any Loan Party or any other party to any Loan Document to perform its
obligations hereunder or thereunder. No Agent-Related Person shall be under any
obligation to any Lender or participant to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement or any other Loan Document, or to inspect the properties,
books or records of any Loan Party or any Affiliate thereof.

      9.04 RELIANCE BY ADMINISTRATIVE AGENT.

      (a) The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons, and upon advice and statements of
legal counsel (including counsel to any Loan Party), independent accountants and
other experts selected by the Administrative Agent. The Administrative Agent
shall be fully justified in failing or refusing to take any action under any
Loan Document unless it shall first receive such advice or concurrence of the
Required Lenders as it deems appropriate and, if it so requests, it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. The Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement or any
other Loan Document in accordance with a request or consent of the Required
Lenders or all the Lenders, if required hereunder, and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and participants. Where this Agreement expressly permits or prohibits an
action unless the Required Lenders otherwise determine, the

                                       44
<PAGE>

Administrative Agent shall, and in all other instances, the Administrative Agent
may, but shall not be required to, initiate any solicitation for the consent or
a vote of the Lenders.

      (b) For purposes of determining compliance with the conditions to
Borrowing specified in SECTION 4.01, each Lender that has funded its Pro Rata
Share of the Borrowing on the Closing Date shall be deemed to have consented to,
approved or accepted or to be satisfied with, each document or other matter
either sent by the Administrative Agent to such Lender for consent, approval,
acceptance or satisfaction, or required hereunder to be consented to or approved
by or acceptable or satisfactory to a Lender.

      9.05 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless the Administrative Agent shall have received written notice from a Lender
or the Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Required Lenders in accordance with
ARTICLE VIII; provided, however, that unless and until the Administrative Agent
has received any such direction, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Lenders.

      9.06 CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE AGENT.
Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereinafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Loan Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder. Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and the other Loan Parties. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent herein, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of any of the Loan Parties or any of
their respective Affiliates which may come into the possession of any
Agent-Related Person.

      9.07 INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, the Lenders shall indemnify
upon demand each Agent-Related Person (to the extent not reimbursed by or on
behalf of any Loan Party and without limiting the obligation of any Loan Party
to do so), pro rata, and hold harmless each Agent-Related Person from and

                                       45
<PAGE>

against any and all Indemnified Liabilities incurred by it; provided, however,
that no Lender shall be liable for the payment to any Agent-Related Person of
any portion of such Indemnified Liabilities resulting from such Person's gross
negligence or willful misconduct; provided, however, that no action taken in
accordance with the directions of the Required Lenders shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section.
Without limitation of the foregoing, each Lender shall reimburse the
Administrative Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including Attorney Costs) incurred by the Administrative
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Administrative
Agent is not reimbursed for such expenses by or on behalf of the Borrower. The
undertaking in this Section shall survive termination of the Commitments, the
payment of all Obligations hereunder and the resignation or replacement of the
Administrative Agent.

      9.08 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. Bank of America and
its Affiliates may make loans to, accept deposits from, acquire equity interests
in and generally engage in any kind of banking, trust, financial advisory,
underwriting or other business with each of the Loan Parties and their
respective Affiliates as though Bank of America were not the Administrative
Agent hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Bank of America or its Affiliates
may receive information regarding any Loan Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Loan Party or such Affiliate) and acknowledge that the Administrative Agent
shall be under no obligation to provide such information to them. With respect
to its Loans, Bank of America shall have the same rights and powers under this
Agreement as any other Lender and may exercise such rights and powers as though
it were not the Administrative Agent, and the terms "Lender" and "Lenders"
include Bank of America in its individual capacity.

      9.09 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may resign
as Administrative Agent upon 30 days' notice to the Lenders and the Borrower. If
the Administrative Agent resigns under this Agreement, the Required Lenders
shall appoint from among the Lenders a successor administrative agent for the
Lenders which successor administrative agent shall be consented to by the
Borrower at all times other than during the existence of an Event of Default
(which consent of the Borrower shall not be unreasonably withheld or delayed).
If no successor administrative agent is appointed prior to the effective date of
the resignation of the Administrative Agent, the Administrative Agent may
appoint, after consulting with the Lenders and the Borrower, a successor
administrative agent from among the Lenders. Upon the acceptance of its
appointment as successor administrative agent hereunder, such successor
administrative agent shall succeed to all the rights, powers and duties of the
retiring Administrative Agent and the term "Administrative Agent" shall mean
such successor administrative agent and the retiring Administrative Agent's
appointment, powers and duties as Administrative Agent shall be terminated.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this ARTICLE IX and SECTIONS 10.03 and
10.13 shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement. If no successor
administrative agent has accepted appointment as Administrative Agent by the
date which is 30 days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative Agent's resignation shall nevertheless
thereupon become effective and the Lenders shall perform all of the duties of
the Administrative Agent hereunder until such time, if any, as the Required
Lenders appoint a successor agent as provided for above.

      9.10 OTHER AGENTS; LEAD MANAGERS. None of the Lenders or other Persons
identified on the facing page or signature pages of this Agreement as a
"syndication agent," as a "documentation agent," any other type of agent (other
than the Administrative Agent), "joint lead arranger," "joint book manager" or
"lead manager" shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Lenders as such. Without limiting the foregoing, none of the Lenders so
identified shall have or be deemed to have any fiduciary relationship with any
Lender. Each Lender acknowledges that it has not relied, and will not rely, on
any of the Lenders so identified in deciding to enter into this Agreement or in
taking or not taking action hereunder.

                                   ARTICLE X.
                                  MISCELLANEOUS

      10.01 AMENDMENTS, ETC.

      (a) No amendment or waiver of any provision of this Agreement or any other
Loan Document, and no consent to any departure by the Borrower or any other Loan
Party therefrom, shall be effective unless in writing signed by the Required
Lenders and the Borrowers or the applicable Loan Party, as the case may be, and
acknowledged by the Administrative Agent, and each such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given; provided, however, that no such amendment, waiver or consent shall,
unless in writing and signed by each of the Lenders directly affected thereby
and by the Borrowers, and acknowledged by the Administrative Agent, do any of
the following:

      any Commitment terminated pursuant to SECTION 8.02);

            (ii) postpone any date fixed by this Agreement or any other Loan

            (iii) reduce the principal of, or the rate of interest specified
      herein on, any Loan or (subject to clause (B) of the proviso below) any

      or change the manner of computation of any financial covenant used in
      determining the Applicable Rate that would result in a reduction of any
      interest rate on any Loan; provided, however, that only the consent of the
      Required Lenders shall be necessary to amend the definition of "Default
      Rate" or to waive any obligation of the Borrower to pay interest at the
      Default Rate; or

            (iv) amend this Section, or SECTION 2.11, or any provision herein
      providing for unanimous consent or other action by all the Lenders;

and, provided further, that (A) no amendment, waiver or consent shall, unless in
writing and signed by the Administrative Agent in addition to the Required
Lenders or all the Lenders, as the case may be, affect the rights or duties of
the Administrative Agent under this Agreement or any other Loan Document; and
(B) the Agent/Arranger Fee Letter may be amended, or rights or privileges
thereunder waived, in a writing executed only by the parties thereto.
Notwithstanding anything to the contrary herein, any Lender that has failed to
fund any portion of the Loans required to be funded by it hereunder shall not
have any right to approve or disapprove any amendment, waiver or consent
hereunder, except that the Pro Rata Share of such Lender may not be increased
without the consent of such Lender.

                                       47
<PAGE>

      (b) Any amendment to any Loan Document which purports to (i) decrease the
amount of any mandatory prepayment or commitment reduction required by SECTION
2.04 or (ii) change this SECTION 10.01(b), must be by an instrument in writing
executed by Borrower, the Administrative Agent and by the Required Lenders.

      10.02 NOTICES AND OTHER COMMUNICATIONS; FACSIMILE COPIES.

      (a) General. Unless otherwise expressly provided herein, all notices and
other communications provided for hereunder and under the other Loan Documents
shall be in writing (including by facsimile transmission) and mailed, faxed or
delivered, to the address, facsimile number or (subject to subsection (c) below)
electronic mail address specified for notices on SCHEDULE 10.02 (for the
Borrowers, each Guarantor and the Administrative Agent) or the signature pages
hereto (for the other Lenders); or, in the case of the Borrowers, the Guarantors
or the Administrative Agent, to such other address as shall be designated by
such party in a notice to the other parties, and in the case of any other party,
to such other address as shall be designated by such party in a notice to the
Borrower and the Administrative Agent. All such notices and other communications

notices and other communications to the Administrative Agent pursuant to ARTICLE
II shall not be effective until actually received by such Person. Any notice or
other communication permitted to be given, made or confirmed by telephone
hereunder shall be given, made or confirmed by means of a telephone call to the
intended recipient at the number specified on SCHEDULE 10.02 or such Person's
signature page, as applicable, it being understood and agreed that a voicemail
message shall in no event be effective as a notice, communication or

      (b) Effectiveness of Facsimile Documents and Signatures. Loan Documents
may be transmitted and/or signed by facsimile. The effectiveness of any such
documents and signatures shall, subject to applicable Law, have the same force
and effect as manually-signed originals and shall be binding on all Loan
Parties, the Administrative Agent and the Lenders. The Administrative Agent may
also require that any such documents and signatures be confirmed by a
manually-signed original thereof; provided, however, that the failure to request
or deliver the same shall not limit the effectiveness of any facsimile document
or signature.

      (c) Limited Use of Electronic Mail. Electronic mail and internet and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information, and to distribute Loan Documents for
execution by the parties thereto, and may not be used for any other purpose.

      (d) Reliance by Administrative Agent and Lenders. The Administrative Agent
and the Lenders shall be entitled to rely and act upon any notices (including
telephonic Borrowing Notices) purportedly given by or on behalf of the Borrower
even if (i) such notices were not made in a manner specified herein, were
incomplete or were not preceded or followed by any other form of notice
specified herein, or (ii) the terms thereof, as understood by the recipient,
varied from any confirmation thereof. The Borrower shall indemnify each
Agent-Related Person and each Lender from all losses, costs, expenses and
liabilities resulting from the reliance by such Person on each notice
purportedly given by or on behalf of the Borrower. All telephonic notices to and
other communications with the Administrative Agent may be recorded by the
Administrative

                                       48
<PAGE>

Agent, and each of the parties hereto hereby consents to such recording.

      10.03 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or the
Administrative Agent to exercise, and no delay by any such Person in exercising,
any right, remedy, power or privilege hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges herein or therein provided are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

      10.04 ATTORNEY COSTS; EXPENSES AND TAXES. The Borrowers agree (a) to pay
or reimburse (i) the Administrative Agent for all Attorney Costs, and (ii) the

Opinion. The agreements in this Section shall survive the termination of the
Commitments and repayment of all the other Obligations.

      10.05 INDEMNIFICATION. Whether or not the transactions contemplated hereby
are consummated, the Borrowers and each Guarantor (by execution of a Guaranty),
jointly and severally, agree to indemnify, save and hold harmless each
Agent-Related Person, the other Agents, each Arranger, each Documentation Agent,
each Lender, each Syndication Agent and their respective Affiliates, directors,
officers, employees, counsel, agents and attorneys-in-fact (collectively the
"INDEMNITEES") from and against: (a) any and all claims, demands, actions or
causes of action that are asserted against any Indemnitee by any Person (other
than the Administrative Agent or any Lender) relating directly or indirectly to

Loan Documents, the Solvency Opinion, the Commitments, the use or contemplated
use of the proceeds of any Loans, or the relationship of any Loan Party, the
Administrative Agent and the Lenders under this Agreement or any other Loan
Document; (c) without limiting the foregoing, any and all claims, demands,
actions or causes of action that are asserted or imposed against any Indemnitee,
(i) under the application of any Environmental Law applicable to the Borrower or
any of its Subsidiaries or any of their properties or assets, including the
treatment or disposal of Hazardous Substances on any of their properties or
assets, including without limitation the Pipeline Assets (ii) as a result of the
breach or non-compliance by a Borrower or any

                                       49
<PAGE>

Subsidiary with any Environmental Law applicable to the Borrower or any
Subsidiary, (iii) due to past ownership by a Borrower or any Subsidiary of any
of their properties or assets or past activity on any of their properties or
assets including, without limitation, the Pipeline Assets which, though lawful
and fully permissible at the time, could result in present liability, (iv) due
to the presence, use, storage, treatment or disposal of Hazardous Substances on
or under, or the escape, seepage, leakage, spillage, discharge, emission or
release from, any of the properties owned or operated by a Borrower or any
Subsidiary (including any liability asserted or arising under any Environmental
Law), regardless of whether caused by, or within the control of, a Borrower or
such Subsidiary, or (v) due to any other environmental, health or safety
condition in connection with the Loan Documents; (d) any administrative or
investigative proceeding by any Governmental Authority arising out of or related
to a claim, demand, action or cause of action described in subsection (a), (b)
or (c) above; and (e) any and all liabilities (including liabilities under
indemnities), losses, costs or expenses (including Attorney Costs) that any
Indemnitee suffers or incurs as a result of the assertion of any foregoing
claim, demand, action, cause of action or proceeding, or as a result of the
preparation of any defense in connection with any foregoing claim, demand,
action, cause of action or proceeding, in all cases, WHETHER OR NOT ARISING OUT
OF THE NEGLIGENCE OF AN INDEMNITEE, and whether or not an Indemnitee is a party
to such claim, demand, action, cause of action or proceeding (all the foregoing,
collectively, the "Indemnified Liabilities"); provided that no Indemnitee shall
be entitled to indemnification for any claim caused by its own gross negligence
or willful misconduct. The agreements in this Section shall survive the
termination of the Commitments and repayment of all the other Obligations.

      10.06 PAYMENTS SET ASIDE. To the extent that the Borrowers makes a payment
to the Administrative Agent or any Lender, or the Administrative Agent or any
Lender exercises its right of set-off, and such payment or the proceeds of such
set-off or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by the Administrative Agent or such Lender in its
discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any Debtor Relief Law or otherwise, then
(a) to the extent of such recovery, the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Lender severally agrees to pay to the Administrative Agent upon demand its
applicable share of any amount so recovered from or repaid by the Administrative
Agent, plus interest thereon from the date of such demand to the date such
payment is made at a rate per annum equal to the Federal Funds Rate from time to
time in effect.

      10.07 SUCCESSORS AND ASSIGNS.

            (a) The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Borrowers may not assign or otherwise transfer
any of their rights or obligations hereunder without the prior written consent
of each Lender (and any attempted assignment or transfer by the Borrower without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Indemnitees) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

      (b) At any time after the sooner of (x) the occurrence of an Event of
Default or (y) 120 days after the Closing Date, any Lender may assign to one or
more Eligible Assignees all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans at
the time owing to it); provided that (i) except in the case of an assignment of
the entire remaining amount of the assigning Lender's Commitment and the Loans
at the time owing to it or in the case of an

                                       50
<PAGE>

assignment to a Lender or an Affiliate of a Lender or an Approved Fund with
respect to a Lender, the aggregate amount of the Commitment (which for this
purpose includes Loans outstanding thereunder) of the assigning Lender subject
to each such assignment, determined as of the date the Assignment and Acceptance
with respect to such assignment is delivered to the Administrative Agent, shall
not be less than $5,000,000, unless each of the Administrative Agent and, so
long as no Event of Default has occurred and is continuing, the Borrower
otherwise consents (each such consent not to be unreasonably withheld or
delayed), (ii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement with respect to the Loans or the Commitment assigned, except that
this clause (ii) shall not prohibit the assignment of a proportionate part of
all the assigning Lender's rights and obligations in respect of the Facility,
and (iii) the parties to each assignment shall execute and deliver to the
Administrative Agent an Assignment and Acceptance. Subject to acceptance and
recording thereof by the Administrative Agent pursuant to subsection (c) of this
Section, from and after the effective date specified in each Assignment and
Acceptance, the Eligible Assignee thereunder shall be a party hereto and, to the
extent of the interest assigned by such Assignment and Acceptance, have the
rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of SECTIONS
3.07, 10.04 and 10.05). Upon request, the Borrower (at its expense) shall
execute and deliver new or replacement Notes to the assigning Lender and the
assignee Lender. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this subsection shall be treated
for purposes of this Agreement as a sale by such Lender of a participation in
such rights and obligations in accordance with subsection (d) of this Section.

      (c) The Administrative Agent, acting solely for this purpose as an agent
of the Borrower, shall maintain at the Administrative Agent's Office a copy of
each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders, and the Commitments of,
and principal amount of the Loans owing to, each Lender pursuant to the terms
hereof from time to time (the "REGISTER"). The entries in the Register shall be
conclusive, and the Borrower, the Administrative Agent and the Lenders may treat
each Person whose name is recorded in the Register pursuant to the terms hereof
as a Lender hereunder for all purposes of this Agreement, notwithstanding notice
to the contrary. The Register shall be available for inspection by the Borrower
and any Lender, at any reasonable time and from time to time upon reasonable
prior notice.

      (d) Any Lender may, without the consent of, or notice to, the Borrower or
the Administrative Agent, sell participations to one or more banks or other
entities (a "PARTICIPANT") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans owing to it); provided that (i) such Lender's obligations under
this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrower, the Administrative Agent and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement. Any agreement or
instrument pursuant to which a Lender sells such a participation shall provide
that such Lender shall retain the sole right to enforce this Agreement and to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such agreement or instrument may provide that such
Lender will not, without the consent of the Participant, agree to any amendment,
waiver or other modification that would (i) postpone any date upon which any
payment of money is scheduled to be paid to such Participant, (ii) reduce the
principal, interest, fees or other amounts payable to such Participant, or (iii)
release any Guarantor from the Guaranty. Subject to subsection (e) of this
Section, the Borrower agrees that each Participant shall be

                                       51
<PAGE>

entitled to the benefits of SECTIONS 3.01, 3.04 and 3.05 to the same extent as
if it were a Lender and had acquired its interest by assignment pursuant to
subsection (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of SECTION 10.09 as though it were a
Lender, provided such Participant agrees to be subject to SECTION 2.11 as though
it were a Lender.

      (e) A Participant shall not be entitled to receive any greater payment
under SECTION 3.01 or 3.04 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant, unless
the sale of the participation to such Participant is made with the Borrower's
prior written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of SECTION 3.01 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with SECTION 10.15 as though
it were a Lender.

      (f) Any Lender may at any time pledge or assign a security interest in all
or any portion of its rights under this Agreement (including under its Notes, if
any) to secure obligations of such Lender, including any pledge or assignment to
secure obligations to a Federal Reserve Bank; provided that no such pledge or
assignment shall release a Lender from any of its obligations hereunder or
substitute any such pledgee or assignee for such Lender as a party hereto.

      (g) If the consent of the Borrowers to an assignment or to an Eligible
Assignee is required hereunder (including a consent to an assignment which does
not meet the minimum assignment threshold specified in clause (i) of the proviso
to the first sentence of SECTION 10.07(b)), the Borrowers shall be deemed to
have given their consent five Business Days after the date notice thereof has
been delivered by the assigning Lender (through the Administrative Agent) unless
such consent is expressly refused by the Borrowers prior to such fifth Business
Day.

      10.08 CONFIDENTIALITY. Each Lender agrees that it will not disclose
without the prior consent of the Borrowers (other than to directors, officers,
employees, auditors, accountants, counsel or other professional advisors of the
Administrative Agent or any Lender) any information with respect to the Borrower
or its Subsidiaries, which is furnished pursuant to this Agreement and which (i)
the Borrower in good faith considers to be confidential and (ii) is either
clearly marked confidential or is designated by the Borrower to the
Administrative Agent or the Lenders in writing as confidential, provided that
any Lender may disclose any such information (a) as has become generally
available to the public, (b) as may be required or appropriate in any report,
statement or testimony submitted to or required by any municipal, state or
federal regulatory body having or claiming to have jurisdiction over such Lender
or submitted to or required by the Board or the Federal Deposit Insurance
Corporation or similar organizations (whether in the United States of America or
elsewhere) or their successors, (c) as may be required or appropriate in
response to any summons or subpoena in connection with any litigation, (d) in
order to comply with any law, order, regulation or ruling applicable to such
Lender, (e) to any Eligible Assignee of or Participant in, or any prospective
Eligible Assignee of or Participant in, any of its rights or obligations under
this Agreement, provided that such Eligible Assignee or Participant or
prospective Eligible Assignee or Participant executes an agreement containing
provisions substantially similar to those contained in this SECTION 10.08, (f)
in connection with the exercise of any remedy by such Lender following an Event
of Default pertaining to the Loan Documents, (g) in connection with any
litigation involving such Lender pertaining to the Loan Documents, (h) to any
Lender or the Administrative Agent, or (i) to any Affiliate of any Lender (it
being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such information and instructed to keep
such information confidential).

                                       52
<PAGE>

      10.09 SET-OFF. In addition to any rights and remedies of the Lenders
provided by law, upon the occurrence and during the continuance of any Event of
Default, each Lender is authorized at any time and from time to time, without
prior notice to the Borrowers or any other Loan Party, any such notice being
waived by the Borrower (on its own behalf and on behalf of each Loan Party) to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Lender to or for the credit or
the account of the respective Loan Parties against any and all Obligations owing
to the Administrative Agent and the Lenders, now or hereafter existing,
irrespective of whether or not the Administrative Agent or such Lender shall
have made demand under this Agreement or any other Loan Document and although
such Obligations may be contingent or unmatured. Each Lender agrees promptly to
notify the Borrowers and the Administrative Agent after any such set-off and
application made by such Lender; provided, however, that the failure to give
such notice shall not affect the validity of such set-off and application.

      10.10 INTEREST RATE LIMITATION. Regardless of any provision contained in
any Loan Document, neither the Administrative Agent nor any Lender shall ever be
entitled to contract for, charge, take, reserve, receive, or apply, as interest
on all or any part of the Obligations, any amount in excess of the Maximum Rate,
and, if any Lender ever does so, then such excess shall be deemed a partial
prepayment of principal and treated hereunder as such and any remaining excess
shall be refunded to the Borrowers. In determining if the interest paid or
payable exceeds the Maximum Rate, the Borrower and the Lenders shall, to the
maximum extent permitted under applicable Law, (a) treat all Borrowings as but a
single extension of credit (and the Lenders and the Borrower agree that such is
the case and that provision herein for multiple Borrowings is for convenience
only), (b) characterize any nonprincipal payment as an expense, fee, or premium
rather than as interest, (c) exclude voluntary prepayments and the effects
thereof, and (d) amortize, prorate, allocate, and spread the total amount of
interest throughout the entire contemplated term of the Obligations. However, if
the Obligations are paid and performed in full prior to the end of the full
contemplated term thereof, and if the interest received for the actual period of
existence thereof exceeds the Maximum Amount, the Lenders shall refund such
excess, and, in such event, the Lenders shall not, to the extent permitted by
Law, be subject to any penalties provided by any Laws for contracting for,
charging, taking, reserving, or receiving interest in excess of the Maximum
Amount. If, contrary to the parties' intent expressed in SECTION 10.16(a), the
Laws of the State of Texas are applicable for purposes of determining the
"Maximum Rate" or the "Maximum Amount," then those terms mean the "weekly
ceiling" from time to time in effect under Texas Finance Code Section 303.001,
as limited by Texas Finance Code Section 303.009. The Borrower agrees that
Chapter 346 of the Texas Finance Code, as amended (which regulates certain
revolving credit loan accounts and revolving tri-party accounts), does not apply
to the Obligations.

      10.11 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

      10.12 INTEGRATION. This Agreement, together with the other Loan Documents,
comprises the complete and integrated agreement of the parties on the subject
matter hereof and thereof and supersedes all prior agreements, written or oral,
on such subject matter. In the event of any conflict between the provisions of
this Agreement and those of any other Loan Document, the provisions of this
Agreement shall control; provided that the inclusion of supplemental rights or
remedies in favor of the Administrative Agent or the Lenders in any other Loan
Document shall not be deemed a conflict with this Agreement. Each Loan Document
was drafted with the joint participation of the respective parties thereto and
shall be construed neither against nor in favor of any party, but rather in
accordance with the fair meaning thereof.

                                       53
<PAGE>

      10.13 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default or Event of Default at the time of any Borrowing, and shall continue
in full force and effect as long as any Loan or any other Obligation shall
remain unpaid or unsatisfied.

      10.14 SEVERABILITY. Any provision of this Agreement and the other Loan
Documents to which the Borrower is a party that is prohibited or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions thereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      10.15 FOREIGN LENDERS. Each Lender that is a "foreign corporation,
partnership or trust" within the meaning of the Code (a "Foreign Lender") shall
deliver to the Administrative Agent, prior to receipt of any payment subject to
withholding under the Code (or after accepting an assignment of an interest
herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Person and entitling it to an exemption
from, or reduction of, withholding tax on all payments to be made to such Person
by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor
thereto (relating to all payments to be made to such Person by the Borrower
pursuant to this Agreement) or such other evidence satisfactory to the Borrower
and the Administrative Agent that such Person is entitled to an exemption from,
or reduction of, U.S. withholding tax. Thereafter and from time to time, each
such Person shall (a) promptly submit to the Administrative Agent such
additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Borrower and the Administrative Agent of any available exemption from or
reduction of, United States withholding taxes in respect of all payments to be
made to such Person by the Borrower pursuant to this Agreement, (b) promptly
notify the Agent of any change in circumstances which would modify or render
invalid any claimed exemption or reduction, and (c) take such steps as shall not
be materially disadvantageous to it, in the reasonable judgment of such Lender,
and as may be reasonably necessary (including the re-designation of its Lending
Office) to avoid any requirement of applicable Laws that the Borrower make any
deduction or withholding for taxes from amounts payable to such Person. If such
Person fails to deliver the above forms or other documentation, then the
Administrative Agent may withhold from any interest payment to such Person an
amount equivalent to the applicable withholding tax imposed by Sections 1441 and
1442 of the Code, without reduction. If any Governmental Authority asserts that
the Administrative Agent did not properly withhold any tax or other amount from
payments made in respect of such Person, such Person shall indemnify the
Administrative Agent therefor, including all penalties and interest, any taxes
imposed by any jurisdiction on the amounts payable to the Agent under this
Section, and costs and expenses (including Attorney Costs) of the Administrative
Agent. The obligation of the Lenders under this Section shall survive the
payment of all Obligations and the resignation or replacement of the
Administrative Agent.

      10.16 GOVERNING LAW.

      (A) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE;

                                       54
<PAGE>

PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH LENDER SHALL RETAIN ALL RIGHTS
ARISING UNDER FEDERAL LAW.

      (b) EACH COMPANY AND OTHER PARTY HERETO, AND EACH GUARANTOR, BY EXECUTION
OF A GUARANTY, AGREES AS TO THIS SECTION 10.16(b). ANY LEGAL ACTION OR
PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT MAY BE
BROUGHT IN THE COURTS OF THE STATE OF NEW YORK SITTING IN THE BOROUGH OF
MANHATTAN OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH STATE, AND
BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE ADMINISTRATIVE
Agent AND EACH LENDER CONSENTS, AND BY EXECUTION OF A GUARANTY, EACH GUARANTOR
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE NON-EXCLUSIVE
JURISDICTION OF THOSE COURTS. THE BORROWERS, EACH GUARANTOR, THE ADMINISTRATIVE
Agent AND EACH LENDER (1) IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING ANY
OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER
DOCUMENT RELATED THERETO, AND (2) IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS
OUT OF ANY OF THE AFOREMENTIONED COURTS IN ANY SUCH ACTION OR PROCEEDING BY THE
MAILING OF COPIES THEREOF BY CERTIFIED MAIL, RETURN RECEIPT REQUESTED, POSTAGE
PREPAID, AT ITS ADDRESS FOR NOTICES DESIGNATED HEREIN. THE BORROWERS, EACH
GUARANTOR, THE ADMINISTRATIVE Agent AND EACH LENDER WAIVES PERSONAL SERVICE OF
ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE MADE BY ANY OTHER MEANS
PERMITTED BY THE LAW OF SUCH STATE. THE BORROWERS AND EACH GUARANTOR, BY ITS
EXECUTION OF A GUARANTY, AGREES TO DESIGNATE AND MAINTAIN AN AGENT FOR SERVICE
OF PROCESS IN NEW YORK IN CONNECTION WITH ACTIONS AND PROCEEDINGS UNDER THE LOAN
DOCUMENTS AND TO DELIVER TO THE ADMINISTRATIVE AGENT EVIDENCE THEREOF.

      10.17 WAIVER OF RIGHT TO TRIAL BY JURY. EACH PARTY TO THIS AGREEMENT AND
EACH GUARANTOR, BY EXECUTION OF A GUARANTY, HEREBY EXPRESSLY WAIVES ANY RIGHT TO
TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION ARISING UNDER ANY
LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE
DEALINGS OF THE PARTIES TO THE LOAN DOCUMENTS OR ANY OF THEM WITH RESPECT TO ANY
LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW
EXISTING OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR
OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM,
DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A
JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A
COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE
COMPANIES TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

      10.18 NO GENERAL PARTNER'S LIABILITY. The Lenders agree for themselves and
their respective successors and assigns, including any subsequent holder of any
Note, that, for so long as the sole asset of the General Partner is the general
partner interest in the MLP, any claim against the Borrowers which may arise
under any Loan Document shall be made only against and shall be limited to the
assets of the Borrower and the Guarantors, and that no judgment, order or
execution entered in any suit, action or proceeding, whether legal or equitable,
on this Agreement, such Note or any of the other Loan

                                       55
<PAGE>

Documents shall be obtained or enforced against the General Partner or its
assets for the purpose of obtaining satisfaction and payment of such Note, the
Indebtedness evidenced thereby or any claims arising thereunder or under this
Agreement or any other Loan Document, any right to proceed against the General
Partner individually or its respective assets being hereby expressly waived,
renounced and remitted by the Lenders for themselves and their respective
successors and assigns. Nothing in this SECTION 10.18, however, shall be
construed so as to prevent the Administrative Agent, any Lender or any other
holder of any Note from commencing any action, suit or proceeding with respect
to or causing legal papers to be served upon the General Partner for the purpose
of obtaining jurisdiction over the Borrowers.

      10.19 ENTIRE AGREEMENT. This Agreement and the other Loan Documents
represent the final agreement between the parties and may not be contradicted by
evidence of prior, contemporaneous, or subsequent oral agreements of the
parties. There are no unwritten oral agreements between the parties.

                          FORM OF SUBSIDIARY GUARANTY

      THIS GUARANTY is executed as of ___________, 2002, jointly and severally
by the undersigned (each a "GUARANTOR" and collectively the "GUARANTORS"), for
the benefit of BANK OF AMERICA, N.A., a national banking association (in its
capacity as Administrative Agent for the benefit of Lenders).

                                    RECITALS

      A. Williams Pipe Line Company, LLC, a Delaware limited liability company,
and Williams Energy Partners L.P., a Delaware limited partnership (collectively,
the "BORROWERS"), Bank of America, N.A., as Administrative Agent (including its
permitted successors and assigns in such capacity, "ADMINISTRATIVE AGENT"), and
the Lenders now or hereafter party to the Credit Agreement (including their
respective permitted successors and assigns, "LENDERS") have entered into a
Credit Agreement, dated as of April ___, 2002 (as amended, modified,
supplemented, or restated from time to time, the "CREDIT AGREEMENT");

      B. Provisions of the Credit Agreement permit Guarantors to directly or
indirectly receive proceeds of Borrowings made pursuant thereto; and

      C. This Guaranty is integral to the transactions contemplated by the Loan
Documents and the execution and delivery hereof, is a condition precedent to
Lenders' obligations to extend credit under the Loan Documents.

      ACCORDINGLY, for adequate and sufficient consideration, the receipt and
adequacy of which are hereby acknowledged, each Guarantor, jointly and
severally, guarantees to Administrative Agent and Lenders the prompt payment of
the Guaranteed Debt (defined below) as follows:

      1. DEFINITIONS. Terms defined in the Credit Agreement have the same
meanings when used, unless otherwise defined, in this Guaranty. As used in this
Guaranty:

      BORROWER and BORROWERS means each of the Persons defined in the preamble
to this Guaranty as Borrowers and includes Borrowers, or either of them, as a
debtor-in-possession, and any receiver, trustee, liquidator, conservator,
custodian, or similar party appointed for Borrowers or for all or substantially
all of a Borrower's assets under any Debtor Relief Law.

      CREDIT AGREEMENT is defined in the recitals to this Guaranty.

      GUARANTEED DEBT means, collectively, (a) the Obligations and (b) all
present and future costs, attorneys' fees, and expenses reasonably incurred by
Administrative Agent or any Lender to enforce Borrowers', any Guarantor's, or
any other obligor's payment of any of the Guaranteed Debt, including, without
limitation (to the extent lawful), all present and future amounts that would
become due but for the operation of Sections 502 or 506 or any other provision
of Title 11 of the United States Code and all present and future accrued and
unpaid interest (including, without limitation, all post-maturity interest and
any post-petition interest in any proceeding under Debtor Relief Laws to which
Borrowers or any Guarantor becomes subject).

                                   Exhibit E
                                     Page 1
                           Form of Subsidiary Guaranty
<PAGE>

      GUARANTOR and GUARANTORS is defined in the preamble to this Guaranty.

      LENDER means, individually, or LENDERS means, collectively, on any date of
determination, the Lenders and their permitted successors and assigns.

      SUBORDINATED DEBT means, for each Guarantor, all present and future
obligations of any Company to such Guarantor, whether those obligations are (a)
direct, indirect, fixed, contingent, liquidated, unliquidated, joint, several,
or joint and several, (b) due or to become due to such Guarantor, (c) held by or
are to be held by such Guarantor, (d) created directly or acquired by assignment
or otherwise, or (e) evidenced in writing.

      2. GUARANTY. This is an absolute, irrevocable, and continuing guaranty of
payment, not collection, and the circumstance that at any time or from time to
time the Guaranteed Debt may be paid in full does not affect the obligation of
any Guarantor with respect to the Guaranteed Debt incurred after that. This
Guaranty remains in effect until the Guaranteed Debt is fully paid and
performed, and all commitments to extend any credit under the Loan Documents
have terminated. No Guarantor may rescind or revoke its obligations with respect
to the Guaranteed Debt. Notwithstanding any contrary provision, it is the
intention of Guarantors, Lenders, and Administrative Agent that the amount of
the Guaranteed Debt guaranteed by each Guarantor by this Guaranty shall be in,
but not in excess of, the maximum amount permitted by fraudulent conveyance,
fraudulent transfer, or similar Laws applicable to each such Guarantor.
Accordingly, notwithstanding anything to the contrary contained in this Guaranty
or any other agreement or instrument executed in connection with the payment of
any of the Guaranteed Debt, the amount of the Guaranteed Debt guaranteed by any
Guarantor under this Guaranty shall be limited to an aggregate amount equal to
the largest amount that would not render such Guarantor's obligations hereunder
subject to avoidance under Section 548 of the United States Bankruptcy Code or
any comparable provision of any applicable state Law.

      3. CONSIDERATION. Each Guarantor represents and warrants that its
liability under this Guaranty may reasonably be expected to directly or
indirectly benefit it.

      4. CUMULATIVE RIGHTS. If any Guarantor becomes liable for any indebtedness
owing by Borrowers to Administrative Agent or any Lender, other than under this
Guaranty, that liability may not be in any manner impaired or affected by this
Guaranty. The Rights of Administrative Agent or Lenders under this Guaranty are
cumulative of any and all other Rights that Administrative Agent or Lenders may
ever have against any Guarantor. The exercise by Administrative Agent or Lenders
of any Right under this Guaranty or otherwise does not preclude the concurrent
or subsequent exercise of any other Right.

      5. PAYMENT UPON DEMAND. If an Event of Default exists, each Guarantor
shall, on demand and without further notice of dishonor and without any notice
having been given to any Guarantor previous to that demand of either the
acceptance by Administrative Agent or Lenders of this Guaranty or the creation
or incurrence of any Guaranteed Debt, pay the amount of the Guaranteed Debt then
due and payable to Administrative Agent and Lenders; provided that, if an Event
of Default exists and Administrative Agent or Lenders cannot, for any reason,
accelerate the Obligations, then the Guaranteed Debt shall be, as among
Guarantors, Administrative Agent, and Lenders, a fully matured, due, and payable
obligation of Guarantors to Administrative Agent and Lenders. It is not
necessary for Administrative Agent or Lenders, in order to enforce that payment
by any Guarantor, first or contemporaneously to institute suit or exhaust
remedies against Borrowers or others liable on any Guaranteed Debt.

                                   Exhibit E
                                     Page 2
                           Form of Subsidiary Guaranty
<PAGE>

      6. SUBORDINATION. The Subordinated Debt is expressly subordinated to the
full and final payment of the Obligations. Upon the occurrence and during the
continuation of an Event of Default, each Guarantor agrees not to accept any
payment of any Subordinated Debt from any Company. In the event of (i) any
insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment,
composition or other similar proceeding relating to any Company, its creditors
as such or its property, (ii) any proceeding for the liquidation, dissolution or
other winding-up of any Company, voluntary or involuntary, whether or not
involving insolvency or bankruptcy proceedings, (iii) any assignment by any
Company for the benefit of creditors, or (iv) any other marshalling of the
assets of a Company, the Obligations (including any interest thereon accruing at
the legal rate after the commencement of any such proceedings and any additional
interest that would have accrued thereon but for the commencement of such
proceedings) shall first be paid in full before any payment or distribution,
whether in cash, securities or other property, shall be made to any holder of
any Subordinated Debt. If any Guarantor receives any payment of any Subordinated
Debt in violation of the terms of this Section, such Guarantor shall hold that
payment in trust for Administrative Agent and Lenders and promptly turn it over
to Administrative Agent, in the form received (with any necessary endorsements),
to be applied to the Obligations.

      7. SUBROGATION AND CONTRIBUTION. Until payment in full of the Guaranteed
Debt and the termination of the Obligations of Lenders to extend credit under
the Loan Documents, (a) no Guarantor may assert, enforce, or otherwise exercise
any Right of subrogation to any of the Rights or Liens of Administrative Agent
or Lenders or any other beneficiary against Borrowers or any other obligor on
the Guaranteed Debt or any collateral or other security or any Right of
recourse, reimbursement, subrogation, contribution, indemnification, or similar
Right against Borrowers or any other obligor on any Guaranteed Debt or any
Guarantor of it, and (b) each Guarantor defers all of the foregoing Rights
(whether they arise in equity, under contract, by statute, under common Law, or
otherwise). Upon payment in full of the Guaranteed Debt and the termination of
the obligations of Lenders to extend credit under the Loan Documents, each
Guarantor shall be subrogated to the rights of the Administrative Agent and
Lenders against Borrowers and the other obligors.

      8. NO RELEASE. Each Guarantor agrees that its obligations under this
Guaranty may not be released, diminished, or affected by the occurrence of any
one or more of the following events: (a) any taking or accepting of any
additional guaranty or any other security or assurance for any Guaranteed Debt;
(b) any release, surrender, exchange, subordination, impairment, or loss of any
collateral securing any Guaranteed Debt; (c) any full or partial release of the
liability of any other obligor on the Obligations, except for any final release
resulting from payment in full of such Obligations; (d) the modification of, or
waiver of compliance with, any terms of any other Loan Document; (e) the
insolvency, bankruptcy, or lack of corporate or partnership power of any other
obligor at any time liable for any Guaranteed Debt, whether now existing or
occurring in the future; (f) any renewal, extension, or rearrangement of any
Guaranteed Debt or any adjustment, indulgence, forbearance, or compromise that
may be granted or given by Administrative Agent or any Lender to any other
obligor on the Obligations; (g) any neglect, delay, omission, failure, or
refusal of Administrative Agent or any Lender to take or prosecute any action in
connection with the Guaranteed Debt or to foreclose, take, or prosecute any
action in connection with any Loan Document; (h) any failure of Administrative
Agent or any Lender to notify any Guarantor of any renewal, extension, or
assignment of any Guaranteed Debt, or the release of any security or of any
other action taken or refrained from being taken by Administrative Agent or any
Lender against Borrowers or any new agreement between Administrative Agent, any
Lender, and Borrower; it being understood that neither Administrative Agent nor
any Lender is required to give any Guarantor any notice of any kind under any
circumstances whatsoever with respect to or in connection

                                   Exhibit E
                                     Page 3
                           Form of Subsidiary Guaranty
<PAGE>

with any Guaranteed Debt, other than any notice required to be given in this
Guaranty; (i) the unenforceability of any Guaranteed Debt against any other
obligor or any security securing same because it exceeds the amount permitted by
Law, the act of creating it is ultra vires, the officers creating it exceeded
their authority or violated their fiduciary duties in connection with it, or
otherwise; (j) any payment of the Obligations to Administrative Agent or any
Lender is held to constitute a preference under any Debtor Relief Law or for any
other reason Administrative Agent or any Lender is required to refund that
payment or make payment to someone else (and in each such instance this Guaranty
will be reinstated in an amount equal to that payment); or (k) any other
circumstance which might otherwise constitute a defense available to, or a legal

liability with respect to the Guaranteed Debt (or any part thereof) shall not be
affected by any renewal or extension in the time of payment of the Obligations

Rights by which it might be entitled to require suit on an accrued Right of
action in respect of any Guaranteed Debt or require suit against Borrowers or
others.

      10. LOAN DOCUMENTS. By execution hereof, each Guarantor covenants and

term, covenant, or condition. Moreover, each Guarantor acknowledges and agrees
that this Guaranty is subject to the offset provisions of the Loan Documents in

has executed and delivered this Guaranty after reviewing the terms and
conditions of the Loan Documents and such other information as it has deemed
appropriate in order to make its own credit analysis and decision to execute and
deliver this Guaranty. Each Guarantor confirms that it has made its own
independent investigation with respect to Borrower's creditworthiness and is not
executing and delivering this Guaranty in reliance on any representation or
warranty by Administrative Agent or any Lender as to that creditworthiness. Each
Guarantor expressly assumes all responsibilities to remain informed of the
financial condition of Borrowers and any circumstances affecting Borrower's
ability to perform under the Loan Documents to which it is a party.

      12. LOAN DOCUMENT. This Guaranty is a Loan Document and is subject to the
applicable provisions of ARTICLES 1 and 10 of the Credit Agreement, including,

Administrative Agent for each Lender under the Credit Agreement. All Rights
granted to Administrative Agent under or in connection with this Guaranty are
for each Lender's ratable benefit. Administrative Agent may, without the joinder
of any Lender, exercise any Rights in Administrative Agent's or Lenders' favor
under or in connection with this Guaranty. Administrative Agent's and each
Lender's Rights and obligations vis-a-vis each other may be subject to one or
more separate agreements between those parties. However, no Guarantor is
required to inquire about any such agreement or is subject to any of its terms

Guarantor nor its successors or assigns is entitled to any benefits or

Administrative Agent. Each Guarantor hereunder expressly agrees that its
obligations arising hereunder shall not be affected or diminished by any such
additional guaranties. Each Guarantor agrees that it shall not be necessary or
required that the Administrative Agent or any Lender exercise any right, assert
any claim or demand or enforce any remedy against any Borrowers, the other
Guarantors, or any other Person who has guaranteed the Guaranteed Debt before or
as a condition to the obligations of any Guarantor hereunder.

      17. PARTIES. This Guaranty benefits Administrative Agent, Lenders, and
their respective successors and assigns and binds Guarantors and their
respective successors and assigns. Upon appointment of any successor
Administrative Agent under the Credit Agreement, all of the Rights of
Administrative Agent under this Guaranty automatically vest in that new
Administrative Agent as successor Administrative Agent on behalf of Lenders
without any further act, deed, conveyance, or other formality other than that
appointment. The Rights of Administrative Agent and Lenders under this Guaranty
may be transferred with any assignment of the Guaranteed Debt pursuant to and in
accordance with the terms of the Credit Agreement. The Credit Agreement contains
provisions governing assignments of the Guaranteed Debt and of Rights and
obligations under this Guaranty.

                           FORM OF OPINION OF COUNSEL

                                 April ___, 2002

To each of the Lenders parties to the Credit
Agreement referred to below, and

      In rendering the opinion expressed below, we have assumed, with your
permission, without independent investigation or inquiry, (a) the due

examination or investigation to verify the accuracy or completeness of any
financial, accounting, or statistical information set forth in the Loan
Documents or otherwise furnished to you and, accordingly, express no opinion
with respect thereto.

      Insofar as our opinion expressed below relates to the matters set forth in
the above-mentioned opinion letter, we have assumed without independent
investigation the correctness of the matters set forth in such opinion, and our

            provisions relating to subrogation rights, delay or omission of

                           FORM OF OPINION OF COUNSEL

April ___, 2002

To each of the Lenders parties to the Credit
Agreement referred to below, and
BANK OF AMERICA, N.A., as
Administrative Agent for the Lenders

Ladies and Gentlemen:

      I am General Counsel of The Williams Companies, Inc. and have acted as
counsel to (i) Williams Pipe Line Company, LLC, a Delaware limited liability
company ("WILLIAMS LLC"), (ii) Williams Energy Partners, L.P. (the "MLP" and,
together with Williams LLC, the "BORROWERS"), and (iii) Williams GP, LLC (the
"GENERAL PARTNER," and together with the Borrowers and the Guarantors, the
"TRANSACTION PARTIES") in connection with the Credit Agreement dated as of April
__, 2002, by and among the Borrowers, the Lenders party thereto, Bank of
America, N.A., as Administrative Agent for the Lenders, and the other agents and
lenders therein named (the "AGREEMENT"). This opinion is furnished to you at the
request of the Borrowers pursuant to Section 4.01(a)(vi) of the Agreement. Terms
defined in the Agreement not otherwise defined herein are used herein as therein
defined.

      In connection with the opinions expressed herein, I, or attorneys
reporting to me, have examined and relied upon copies of the following
documents:

      (a)   the Agreement, including all exhibits, schedules, and attachments
            thereto, and any Notes issued pursuant thereto (the "NOTES");

      (b)   [INCLUDE THE FOLLOWING IF APPLICABLE...the Guaranties dated as of
            even date with the Agreement executed by each of the Guarantors (the
            "GUARANTY")...];

      (c)   Certificates of the Secretary of State of the State of Delaware
            dated ___________, 2002, attesting to the continued existence and
            good standing of the Transaction Parties in Delaware; and

      (d)   the Organization Documents of the Transaction Parties and all
            amendments thereto.

      Those documents identified in items (a) and (b) above are collectively
referred to herein as the "CREDIT DOCUMENTS." In connection with this opinion, I
or other attorneys acting under my supervision have (i) investigated such
questions of law, (ii) examined such partnership and company documents and
records of the Transaction Parties and certificates of public officials, and
(iii) received such information from officers and representatives of the
Transaction Parties and made such investigations as I or other attorneys under
my supervision have deemed necessary or appropriate for the purposes of this
opinion. I have not, nor have other attorneys under my supervision, conducted
independent investigations or inquiries to determine the existence of matters,
actions, proceedings, items, documents, facts, judgments, decrees, franchises,
certificates, permits, or the like and have made no independent search of the
records of any court, arbitrator, or governmental authority affecting any
Person, and no inference as to my knowledge thereof shall be drawn from the fact
of my representation of any party or otherwise.

                                  Exhibit F-2
                                     Page 1
                           Form of Opinion of Counsel
<PAGE>

      In rendering the opinions herein, I have assumed without independent
verification (i) the genuineness of all signatures of the Lenders and the
Administrative Agent, (ii) the capacity of the signing officers of each of the
Lenders and the Administrative Agent, (iii) the authenticity of all documents
submitted to me as original and the conformity with the authentic originals of
all documents submitted to me as copies, and (iv) the due execution and
delivery, pursuant to due authorization, of the Agreement by the Lenders and the
Administrative Agent and the enforceability of the Agreement against the Lenders
and the Administrative Agent.

      Based upon and subject to the foregoing and the other qualifications,
limitations, and assumptions set forth below and upon such other matters as I
have deemed appropriate, I am of the opinion that:

      1.    The MLP is a limited partnership duly organized, validly existing,
            and in good standing under the laws of the State of Delaware;
            Williams LLC is a limited liability company duly organized, validly
            existing, and in good standing under the laws of the State of
            Delaware; and the General Partner is a limited liability company
            duly organized, validly existing, and in good standing under the
            laws of the State of Delaware.

      2.    Each Transaction Party has the partnership or company power and
            authority to own and lease its property and to conduct the business
            in which it is currently engaged. The execution, delivery, and
            performance by each of the Transaction Parties of the Credit
            Documents and the consummation of the transactions contemplated by
            the Credit Documents are (a) within its partnership or company
            powers, (b) will not contravene (i) the Organization Documents of
            any Transaction Party, (ii) any law, rule, or regulation applicable
            to any Transaction Party (including, without limitation, Regulation
            X of the Board of Governors of the Federal Reserve System), or (iii)
            any contractual or legal restriction, and (c) will not result in or
            require the creation or imposition of any Lien prohibited by the
            Credit Documents.

      3.    The Agreement has been duly authorized, executed, and delivered to
            the Administrative Agent by the Borrowers, and the Guaranty has been
            duly authorized, executed, and delivered to the Administrative Agent
            by each of the Guarantors.

      4.    No authorization, approval, or other action by, and no notice to or
            filing with, any governmental authority or regulatory body is
            required for the due execution, delivery, and performance by any
            Transaction Party of the Credit Documents to which it is a party or
            the consummation of the transactions contemplated by the Credit
            Documents, except, in the case of such performance, for such
            authorizations, approvals, actions, notices, and filings which have
            been made or obtained.

      5.    To my knowledge there are no pending or overtly threatened actions
            or proceedings against any Transaction Party before any court,
            governmental agency, or arbitrator that purport to affect the
            legality, validity, binding effect, or enforceability of the Credit
            Documents, or that would reasonably be expected to have a materially
            adverse effect upon the financial condition or operations of any
            Transaction Party, taken as a whole.

      6.    No Transaction Party is an "investment company" or a company
            "controlled" by an "investment company" within the meaning of the
            Investment Company Act of 1940, as amended. No Transaction Party is
            a "holding company," or a "subsidiary company" of a "holding
            company," or an "affiliate" of a "holding company" or of a
            "subsidiary

                                  Exhibit F-2
                                     Page 2
                           Form of Opinion of Counsel
<PAGE>

            company" of a "holding company," or a "public utility" within the
            meaning of the Public Utility Holding Company Act of 1935, as
            amended.

      7.    In any action or proceeding arising out of or relating to the Credit
            Documents in any court of the State of Oklahoma or in any Federal
            court sitting in the State of Oklahoma, assuming (i) proper venue,
            jurisdiction, and a full and proper presentation of the issues and
            the law to the court, (ii) such action or proceeding is not
            dismissed on the basis of an inconvenient forum, and (iii) that the
            court properly applies Oklahoma law, such court would (a) recognize
            and give effect to the provisions of the Credit Documents that set
            forth the governing law, and (b) construe the Credit Documents in
            accordance with the internal laws of the State of New York. Subject
            to the foregoing and without limiting the generality thereof, a
            court of the State of Oklahoma or a Federal court sitting in the
            State of Oklahoma would apply the usury law of the State of New
            York, and would not apply the usury law of the State of Oklahoma, to
            the Credit Documents. However, if a court were to hold that the
            Credit Documents are governed by or are to be construed in
            accordance with the laws of the State of Oklahoma, the Agreement,
            when executed and delivered by the parties thereto, would be, under
            the laws of the State of Oklahoma, legal, valid, and binding
            obligations of the Borrower, enforceable against the Borrower in
            accordance with its terms, and the Guaranty would be, under the laws
            of the State of Oklahoma, legal, valid and binding obligations of
            each Guarantor, enforceable against each Guarantor in accordance
            with its terms.

      The opinions expressed in this letter are subject to the following
additional qualifications and limitations:

      A.    My opinion in paragraph 1 with respect to the organization and good
            standing of the Borrowers, the Guarantor and the General Partner is
            based solely on Certificates, dated as of ___________, 2002, from
            the Secretary of State of the State of Delaware, certifying as to
            such matters.

      B.    My opinion in the last sentence of paragraph 7 above is subject,
            insofar as enforceability is concerned, to the effect of any
            applicable bankruptcy, insolvency, reorganization, fraudulent
            conveyance, moratorium, or similar law affecting creditors' rights
            and remedies generally.

      C.    My opinion in the last sentence of paragraph 7 above is subject,
            insofar as enforceability is concerned, to the effect of general
            principles of equity including principles of commercial
            reasonableness, good faith, and fair dealing (regardless of whether
            considered in a proceeding in equity or at law).

      D.    I express no opinion with respect to the enforceability of any of
            the following: (i) indemnification provisions to the extent the same
            are violative of federal or state securities laws, rules, or
            regulations, or of public policy, (ii) clauses waiving right to
            trial by jury, exculpation clauses, or clauses granting offset
            rights to the Banks or against any deposits or in respect of matured
            claims, (iii) clauses relating to recovery of attorneys' fees in
            connection with the enforcement of obligations, (iv) clauses
            relating to release of unmatured claims and integration clauses to
            the effect that no representation was made other than as appears in
            the Agreement, (v) clauses purporting to waive unmatured rights,
            representations, warranties, or affirmative or negative covenants to
            the extent such representations, warranties, or covenants can be
            construed to be independent clauses

                                  Exhibit F-2

            which purport to be legal, valid, binding, and enforceable by
            themselves, as distinguished from being clauses that trigger an
            event of default, and severability and similar clauses, and (vi)
            clauses that incorporate by reference a document or instrument or
            agreement not in existence on the date hereof to the extent that any
            such document, instrument, or agreement is the basis of an effort to
            enforce the Agreement, insofar as any of the foregoing are contained
            in the Agreement.

      E.    I express no opinion as to the effect on the opinions herein stated
            of compliance or non-compliance by any Lender with any applicable
            state, federal, or other laws or regulations applying only to banks,
            or the legal or regulatory status of any Lender.

      F.    My opinion in paragraph 7 above assumes (i) application of New York
            law would not be found to be contrary to a fundamental policy of a
            state with a materially greater interest in determining the question
            presented and the laws of which would govern in absence of an
            effective choice of law, and (ii) [one of] the Syndication Agents,
            [one of] the Joint Lead Arrangers and Joint Book Managers, and one
            or more Lenders, each have their principal place of business located
            in the State of New York, and one or more Lenders has a place of
            business located in the State of New York.

      G.    Qualification of any statement or opinion herein by the use of the
            words "to my knowledge" means that during the course of
            representation in connection with the transactions contemplated by
            the Agreement, no information has come to the attention of me or
            attorneys reporting to me that would give me or such attorneys
            current actual knowledge of the existence of facts or matters so
            qualified. I have not undertaken any investigation to determine the
            existence of facts, and no inference as to my knowledge thereof
            shall be drawn from the fact of the representation by me or
            attorneys reporting to me of any party or otherwise.

      I am admitted to practice law in the States of Oklahoma and New York, and,
accordingly, the opinions expressed herein are based upon and limited
exclusively to the laws of the States of Oklahoma and New York, the General
Corporation Law of the State of Delaware and the laws of the United States of
America insofar as any of such laws are applicable. I render no opinion with
respect to any other laws.

      This opinion letter is solely for the benefit of the Lenders and the
Administrative Agent, their respective successors, assigns, participants, and
other transferees and counsel for the Persons referred to in this sentence, in
consummating the transaction contemplated by the Credit Documents, and may not
be used or relied upon by, quoted, transmitted to, or filed with any other
Person or for any other purpose whatsoever without in each instance my prior
written consent. This opinion speaks as of its date, and I undertake no, and
hereby expressly disclaim any, duty to advise you as to any changes of fact or
law coming to my attention after the date hereof.

                                            Very truly yours,

                                            William G. von Glahn

                                  Exhibit F-2
