Interest Period offered by major banks in New York City at approximately 11:00
a.m. New York City time, on the day that is two Business Days preceding the
first day of such US LIBOR Loan, Term LIBOR Loan or Term-B LIBOR Loan. In the
event that Administrative Agent is unable to obtain any such quotation as
provided above, it will be deemed that the US LIBOR Rate pursuant to such US
LIBOR Loan, Term LIBOR Loan or Term-B LIBOR Loan cannot be determined. In the
event that the Board of Governors of the Federal Reserve System shall impose a
Reserve Percentage with respect to LIBOR deposits of any Lender, then for any
period during which such Reserve Percentage shall apply, the US LIBOR Rate shall
be equal to the amount determined above divided by an amount equal to 1 minus
the Reserve Percentage. "Reserve Percentage" means the maximum aggregate reserve
requirement (including all basic, supplemental, marginal, special, emergency and
other reserves) which is imposed on member banks of the Federal Reserve System
against "Euro-currency Liabilities" as defined in Regulation D. Without limiting
the effect of the foregoing, the Reserve Percentage shall reflect any other
reserves required to be maintained by such member banks with respect to (a) any
category of liabilities which includes deposits by reference to which the US
LIBOR Rate is to be determined, or (b) any category of extensions of credit or
other assets which include US LIBOR Loans, Term LIBOR Loans or Term-B LIBOR
Loans. The US LIBOR Rate for any US LIBOR Loan, Term LIBOR Loan or Term-B LIBOR
Loan shall change whenever the Reserve Percentage changes.

     "US LIBOR Rate Margin" means the percent per annum set forth on the Pricing
Grid as the "US LIBOR Rate Margin" based on the Applicable Leverage Level in
effect on such date. Changes in the applicable US LIBOR Rate Margin will occur
automatically without prior notice as changes in the Applicable Leverage Level
occur. Administrative Agent will give notice promptly to US Borrower and US
Lenders of changes in the US LIBOR Rate Margin.

     "US Loans" has the meaning given such term in Section 2A.1 hereof.

               ARTICLE IIA - The US Loans and US Letters of Credit

     Section 2A.1. Commitments to Lend; US Notes. Subject to the terms and
conditions hereof, each US Lender agrees to make loans to US Borrower (herein
called such US Lender's "US Loans") upon US Borrower's request from time to time
during the US Commitment Period, provided that (a) subject to Sections 3.3, 3.4
and 3.6, all US Lenders are requested to make US Loans of the same Type in
accordance with their respective Percentage Shares and as part of the same
Borrowing, (b) after giving effect to such US Loans, the US Facility Usage does
not exceed the US Commitment determined as of the date on which the requested US
Loans are to be made, and (c) after giving effect to such US Loans the US Loans
by each US Lender plus the existing US LC Obligations of such US Lender does not
exceed such US Lender's Commitment. The aggregate amount of all US Loans in any
Borrowing must be equal to $2,000,000 or any higher integral multiple of
$250,000. The obligation of US Borrower to repay to each US Lender the aggregate
amount of all US Loans made by such US Lender to US Borrower, together with
interest accruing in connection therewith, shall be evidenced by a single
promissory note (herein called such US Lender's "US Note") made by US Borrower
payable to the order of such US Lender in the form of Exhibit A-1 with
appropriate insertions. The amount of principal owing on any US Lender's US Note
at any given time shall be the aggregate amount of all US Loans theretofore made
by such US Lender minus all payments of principal theretofore received by such
US Lender on such US Note. Interest on each US Note shall accrue and be due and
payable as provided herein and therein. Each US Note shall be due and payable as
provided herein and therein, and shall be due and payable in full on the US
Maturity Date. Subject to the terms and conditions of this Agreement, US
Borrower may borrow, repay, and reborrow under this Section 2A.1. US Borrower
may have no more than seven Borrowings of LIBOR Loans outstanding at any time.
All payments of principal and interest on the US Loans shall be made in Dollars.

                                       30

<PAGE>

       Section 2A.2. Requests for US Loans. US Borrower must give to
Administrative Agent written notice (or telephonic notice promptly confirmed in
writing) of any requested Borrowing of US Loans to be funded by US Lenders. Each
such notice constitutes a "Borrowing Notice" hereunder and must:

              (a     specify (i) the aggregate amount of any such Borrowing of
       new US Base Rate Loans and the date on which such US Base Rate Loans are
       to be advanced, or (ii) the aggregate amount of any such Borrowing of new
       US LIBOR Loans, the date on which such US LIBOR Loans are to be advanced
       (which shall be the first day of the Interest Period which is to apply
       thereto), and the length of the applicable Interest Period; and

              (b     be received by Administrative Agent not later than 11:00
       a.m., Boston, Massachusetts time, on (i) the day on which any such US
       Base Rate Loans are to be made, or (ii) the third Business Day preceding
       the day on which any such US LIBOR Loans are to be made.

              (c)    If any requested Borrowing of US Loans or portion thereof
       is to be utilized by US Borrower exclusively for working capital purposes
       (such Borrowing or such portion being called a "Working Capital
       Borrowing"), US Borrower shall specify in the Borrowing Notice that such
       Borrowing or such portion is a Working Capital Borrowing. In addition,
       any repayment of a US Loan that is intended as a repayment of all or any
       part of the outstanding amount of one or more Working Capital Borrowings
       shall be so identified to the Administrative Agent at the time of such
       repayment.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B-1, duly completed. Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by US Borrower as to the matters which are required
to be set out in such written confirmation. Upon receipt of any such Borrowing
Notice, Administrative Agent shall give each US Lender prompt notice of the
terms thereof. If all conditions precedent to such new US Loans have been met,
each US Lender will on the date requested promptly remit to Administrative Agent
at Administrative Agent's office in Boston, Massachusetts the amount of such US
Lender's new US Loan in immediately available funds, and upon receipt of such
funds, unless to its actual knowledge any conditions precedent to such US Loans
have been neither met nor waived as provided herein, Administrative Agent shall
promptly make such US Loans available to US Borrower. Unless Administrative
Agent shall have received prompt notice from a US Lender that such US Lender
will not make available to Administrative Agent such US Lender's new US Loan,
Administrative Agent may in its discretion assume that such US Lender has made
such US Loan available to Administrative Agent in accordance with this section,
and Administrative Agent may if it chooses, in reliance upon such assumption,
make such US Loan available to US Borrower. If and to the extent such US Lender
shall not so make its new US Loan available to Administrative Agent, such US
Lender and US Borrower severally agree to pay or repay to Administrative Agent
within three days after demand the amount of such US Loan together with interest
thereon, for each day from the date such amount was made available to US
Borrower until the date such amount is paid or repaid to Administrative Agent,
with interest at (i) the Federal Funds Rate, if such US Lender is making such
payment and (ii) the interest rate

                                       31

<PAGE>

applicable at the time to the other new US Loans made on such date, if US
Borrower is making such repayment. If neither such US Lender nor US Borrower
pays or repays to Administrative Agent such amount within such three-day period,
Administrative Agent shall be entitled to recover from US Borrower, on demand in
lieu of the interest provided for in the preceding sentence, interest thereon at
the Default Rate, calculated from the date such amount was made available to US
Borrower. The failure of any US Lender to make any new US Loan to be made by it
hereunder shall not relieve any other US Lender of its obligation hereunder, if
any, to make its new US Loan, but no US Lender shall be responsible for the
failure of any other US Lender to make any new Loan to be made by such other US
Lender. All Borrowings of US Loans shall be advanced to US Borrower in Dollars.

       Section 2A.3. Continuations and Conversions of Existing US Loans. US
Borrower may make the following elections with respect to US Loans already
outstanding: to Convert, in whole or in part, US Base Rate Loans to US LIBOR
Loans, to Convert, in whole or in part, US LIBOR Loans to US Base Rate Loans on
the last day of the Interest Period applicable thereto, and to Continue, in
whole or in part, US LIBOR Loans beyond the expiration of such Interest Period
by designating a new Interest Period to take effect at the time of such
expiration. In making such elections, US Borrower may combine existing US Loans
made pursuant to separate Borrowings into one new Borrowing or divide existing
US Loans made pursuant to one Borrowing into separate new Borrowings, provided
that US Borrower may have no more than seven Borrowings of US LIBOR Loans
outstanding at any time. To make any such election, US Borrower must give to
Administrative Agent written notice (or telephonic notice promptly confirmed in
writing) of any such Conversion or Continuation of existing US Loans, with a
separate notice given for each new Borrowing. Each such notice constitutes a
"Continuation/Conversion Notice" hereunder and must:

              (a     specify the existing US Loans which are to be Continued or
       Converted;

              (b     specify (i) the aggregate amount of any Borrowing of US
       Base Rate Loans into which such existing US Loans are to be Continued or
       Converted and the date on which such Continuation or Conversion is to
       occur, or (ii) the aggregate amount of any Borrowing of US LIBOR Loans
       into which such existing US Loans are to be Continued or Converted, the
       date on which such Continuation or Conversion is to occur (which shall be
       the first day of the Interest Period which is to apply to such US LIBOR
       Loans), and the length of the applicable Interest Period; and

              (c     be received by Administrative Agent not later than 11:00
       a.m., Boston, Massachusetts time, on (i) the day on which any such
       Continuation or Conversion to US Base Rate Loans is to occur, or (ii) the
       third Business Day preceding the day on which any such Continuation or
       Conversion to US LIBOR Loans is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C-1, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by US Borrower as to the matters which
are required to be set out in such written confirmation. Upon receipt of any
such Continuation/Conversion Notice, Administrative Agent shall give each US
Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice
shall be

                                       32

<PAGE>

irrevocable and binding on US Borrower. During the continuance of any Default,
US Borrower may not make any election to Convert existing US Loans into US LIBOR
Loans or Continue existing US Loans as US LIBOR Loans beyond the expiration of
their respective and corresponding Interest Period then in effect. If (due to
the existence of a Default or for any other reason) US Borrower fails to timely
and properly give any Continuation/Conversion Notice with respect to a Borrowing
of existing US LIBOR Loans at least three days prior to the end of the Interest
Period applicable thereto, such US LIBOR Loans, to the extent not prepaid at the
end of such Interest Period, shall automatically be Converted into US Base Rate
Loans at the end of such Interest Period. No new funds shall be repaid by US
Borrower or advanced by any US Lender in connection with any Continuation or
Conversion of existing US Loans pursuant to this section, and no such
Continuation or Conversion shall be deemed to be a new advance of funds for any
purpose; such Continuations and Conversions merely constitute a change in the
interest rate applicable to already outstanding Loans.

       Section 2A.4. Use of Proceeds. US Borrower shall use (i) all US Loans
designated as Working Capital Borrowings pursuant to Section 2A.2(c) to provide
working capital (including, without limitation, to make distributions to the
partners of Restricted Persons), and (ii) all US Loans not designated as Working
Capital Borrowings pursuant to Section 2A.2(c) to (a) refinance all outstanding
indebtedness under the Existing Agreement, and (b) finance capital expenditures
of any Restricted Person, pay reimbursement obligations of US Letters of Credit,
provide working capital for operations and for other general business purposes,
including acquisitions, but not to pay distributions to partners of Restricted
Persons. US Borrower shall use all US Letters of Credit for its and its
Subsidiaries' general corporate purposes (but not to pay distributions to
partners of Restricted Persons) including in relation to the purchase or
exchange by US Borrower of Petroleum Products. In no event shall the funds from
any US Loan or any US Letter of Credit be used directly or indirectly by any
Person for personal, family, household or agricultural purposes or for the
purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or
carrying any "margin stock" (as such term is defined in Regulation U promulgated
by the Board of Governors of the Federal Reserve System) or to extend credit to
others directly or indirectly for the purpose of purchasing or carrying any such
margin stock. US Borrower represents and warrants that US Borrower is not
engaged principally, or as one of US Borrower's important activities, in the
business of extending credit to others for the purpose of purchasing or carrying
such margin stock.

       Section 2A.5. Interest Rates and Fees.
       (a    Interest Rates. Each US Loan shall bear interest as follows: (i)
unless the Default Rate shall apply, (A) each US Base Rate Loan shall bear
interest on each day outstanding at the US Base Rate plus the US Base Rate
Margin in effect on such day, and (B) each US LIBOR Loan shall bear interest on
each day during the related Interest Period at the related US LIBOR Rate plus
the US LIBOR Rate Margin in effect on such day, and (ii) during a Default Rate
Period, all US Loans shall bear interest on each day outstanding at the
applicable Default Rate. If an Event of Default based upon Section 8.1(a),
Section 8.1(b) or, with respect to US Borrower, based upon Section 8.1(i)(i),
(i)(ii) or (i)(iii) exists and the US Loans are not bearing interest at the
Default Rate, the past due principal and past due interest shall bear interest
on each day outstanding at the applicable Default Rate. The interest rate shall
change whenever the applicable US Base Rate, the US LIBOR Rate, US Base Rate
Margin, or the US LIBOR Rate

                                       33

<PAGE>

Margin changes. In no event shall the interest rate on any US Loan exceed the
Highest Lawful Rate.

       (b   Commitment Fees. In consideration of each US Lender's commitment to
make US Loans, US Borrower will pay to Administrative Agent for the account of
each US Lender a commitment fee determined on a daily basis equal to the US
Commitment Fee Rate in effect on such day times such US Lender's Percentage
Share of the unused portion of the US Commitment on each day during the US
Commitment Period, determined for each such day by deducting from the amount of
the US Commitment at the end of such day the US Facility Usage. This commitment
fee shall be due and payable in arrears on the last day of each Fiscal Quarter
and at the end of the US Commitment Period. US Borrower shall have the right
from time to time to permanently reduce the US Commitment, provided that (i)
notice of such reduction is given not less than 2 Business Days prior to such
reduction, (ii) the resulting US Commitment is not less than the US Facility
Usage and (iii) each partial reduction shall be in an amount at least equal to
$500,000 and in multiples of $100,000 in excess thereof.

       (c   Administrative Agent's Fees. In addition to all other amounts due to
Administrative Agent under the Loan Documents, US Borrower will pay fees to
Administrative Agent as described in a letter agreement of even date herewith
between Administrative Agent and US Borrower.

       Section 2A.6. Optional Prepayments. US Borrower may, upon three Business
Days' notice, as to US LIBOR Loans, or one Business Day's notice, as to US Base
Rate Loans, to Administrative Agent (and Administrative Agent will promptly give
notice to the other US Lenders) from time to time and without premium or penalty
prepay the US Loans, in whole or in part, so long as the aggregate amounts of
all partial prepayments of principal on the US Loans equals $1,000,000 or any
higher integral multiple of $250,000, and so long as US Borrower does not make
any prepayments which would reduce the unpaid principal balance of the US Loans
to less than $100,000 without first either (i) terminating this Agreement or
(ii) providing assurance satisfactory to Administrative Agent in its discretion
that US Lenders' legal rights under the Loan Documents are in no way affected by
such reduction. Upon receipt of any such notice, Administrative Agent shall give
each US Lender prompt notice of the terms thereof. Each prepayment of principal
of a US Loan under this section shall be accompanied by all interest then
accrued and unpaid on the principal so prepaid. Any principal or interest
prepaid pursuant to this section shall be in addition to, and not in lieu of,
all payments otherwise required to be paid under the Loan Documents at the time
of such prepayment.

                                       34

       Section 2A.7. Mandatory Prepayments.

       (a     Without limiting the requirements of Section 7.5 hereof regarding
the consent of Majority US Lenders to sales of property by Restricted Persons
which are not permitted by Section 7.5, the proceeds of any sale of property
(net of all reasonable costs and expenses, but excluding proceeds consisting of
tangible property to be used in the business of Restricted Persons) by any
Restricted Person (other than a sale of property permitted under Section 7.5
hereof) shall be placed in a collateral account under the control of
Administrative Agent in a manner satisfactory to Administrative Agent
immediately upon such Restricted Person's receipt of such proceeds and
maintained therein for a period of ninety (90) days following the date of
receipt thereof in cash (in this Section 2A.7(a) referred to as the "Collateral
Period"). If any consideration consists of an instrument or security, the
Collateral Period shall, with respect to each amount of cash received in respect
thereof, continue until ninety (90) days following such Restricted Person's
receipt of such cash unless, pursuant to the following sentence, an approved
investment included such cash; any cash in a collateral account may be invested
in Cash Equivalents designated by US Borrower. During each Collateral Period, US
Borrower may propose to invest such proceeds in other property subject to the
approval of Majority US Lenders, and shall thereafter invest such proceeds in
such property so approved by Majority US Lenders. At the end of each Collateral
Period or, if an investment is so proposed and approved during such Collateral
Period, within one hundred-eighty (180) days after such proposed investment has
been so approved by Majority US Lenders, any such proceeds which have not been
so invested by US Borrower shall be applied to the reduction of the outstanding
principal balance of the US Loans at such time, and the US Commitment shall be
reduced by an amount equal to the prepayment applied to the US Loans.

       (b     If at any time the US Facility Usage exceeds the US Commitment
(whether due to a reduction in the US Commitment in accordance with this
Agreement, or otherwise), US Borrower shall immediately upon demand prepay the
principal of the US Loans in an amount at least equal to such excess. Each
prepayment of principal under this section shall be accompanied by all interest
then accrued and unpaid on the principal so prepaid. Any principal or interest
prepaid pursuant to this section shall be in addition to, and not in lieu of,
all payments otherwise required to be paid under the Loan Documents at the time
of such prepayment.

       Section 2A.8. US Letters of Credit. Subject to the terms and conditions
hereof, US Borrower may during the US Commitment Period request US LC Issuer to
issue, amend, or extend the expiration date of, one or more US Letters of
Credit, provided that, after taking such US Letter of Credit into account:

              (a     the US Facility Usage does not exceed the US Commitment at
       such time;

              (b     the aggregate amount of US LC Obligations at such time does
       not exceed $10,000,000;

              (c     the expiration date of such US Letter of Credit is prior to
       the earlier of (i) one (1) year after the date of issuance of such US
       Letter of Credit or (ii) the end of the US Commitment Period;

                                       35

<PAGE>

          (d such US Letter of Credit is to be used for general corporate
     purposes of US Borrower or any of its Subsidiaries and is not directly or
     indirectly used to assure payment of or otherwise support any Indebtedness
     of any Person, except Indebtedness of a Restricted Person;

          (e the issuance of such US Letter of Credit will be in compliance with
     all applicable governmental restrictions, policies, and guidelines and will
     not subject US LC Issuer to any cost which is not reimbursable under
     Article III;

          (f the form and terms of such US Letter of Credit are acceptable to US
     LC Issuer in its sole and absolute discretion; and

          (g all other conditions in this Agreement to the issuance of such US
     Letter of Credit have been satisfied.

US LC Issuer will honor any such request if the foregoing conditions (a) through
(g) (in the following Section 2A.9 called the "US LC Conditions") have been met
as of the date of issuance, amendment, or extension of the expiration, of such
US Letter of Credit.

     Section 2A.9.  Requesting US Letters of Credit. US Borrower must make
written application for any US Letter of Credit at least two Business Days
before the date on which US Borrower desires for US LC Issuer to issue such US
Letter of Credit. By making any such written application, unless otherwise
expressly stated therein, US Borrower shall be deemed to have represented and
warranted that the US LC Conditions described in Section 2A.8 will be met as of
the date of issuance of such US Letter of Credit. Each such written application
for a US Letter of Credit must be made in writing in the form and substance of
Exhibit G-1, the terms and provisions of which are hereby incorporated herein by
reference (or in such other form as may mutually be agreed upon by US LC Issuer
and US Borrower). If all US LC Conditions for a US Letter of Credit have been
met as described in Section 2A.8 on any Business Day before 11:00 a.m., Boston,
Massachusetts time, US LC Issuer will issue such US Letter of Credit on the same
Business Day at US LC Issuer's office in Boston, Massachusetts. If the US LC
Conditions are met as described in Section 2A.8 on any Business Day on or after
11:00 a.m., Boston, Massachusetts time, US LC Issuer will issue such US Letter
of Credit on the next succeeding Business Day at US LC Issuer's office in
Boston, Massachusetts. If any provisions of any US LC Application conflict with
any provisions of this Agreement, the provisions of this Agreement shall govern
and control.

     Section 2A.10. Reimbursement and Participations.

     (a Reimbursement by US Borrower. Each Matured US LC Obligation shall
constitute a loan by US LC Issuer to US Borrower. US Borrower promises to pay to
US LC Issuer, or to US LC Issuer's order, on demand, the full amount of each
Matured US LC Obligation, together with interest thereon (i) at the US Base Rate
plus the US Base Rate Margin to and including the second Business Day after the
Matured US LC Obligation is incurred and (ii) at the Default Rate on each day
thereafter.

                                       36

<PAGE>

     (b US Letter of Credit Advances. If the beneficiary of any US Letter of
Credit makes a draft or other demand for payment thereunder then US Borrower
may, during the interval between the making thereof and the honoring thereof by
US LC Issuer, request US Lenders to make US Loans to US Borrower in the amount
of such draft or demand, which US Loans shall be made concurrently with US LC
Issuer's payment of such draft or demand and shall be immediately used by US LC
Issuer to repay the amount of the resulting Matured US LC Obligation. Such a
request by US Borrower shall be made in compliance with all of the provisions
hereof, provided that for the purposes of the first sentence of Section 2A.1,
the amount of such US Loans shall be considered, but the amount of the Matured
US LC Obligation to be concurrently paid by such US Loans shall not be
considered.

     (c Participation by US Lenders. US LC Issuer irrevocably agrees to grant
and hereby grants to each US Lender, and -- to induce US LC Issuer to issue US
Letters of Credit hereunder -- each US Lender irrevocably agrees to accept and
purchase and hereby accepts and purchases from US LC Issuer, on the terms and
conditions hereinafter stated and for such US Lender's own account and risk an
undivided interest equal to such US Lender's Percentage Share of US LC Issuer's
obligations and rights under each US Letter of Credit issued hereunder and the
amount of each Matured US LC Obligation paid by US LC Issuer thereunder. Each US
Lender unconditionally and irrevocably agrees with US LC Issuer that, if a
Matured US LC Obligation is paid under any US Letter of Credit for which US LC
Issuer is not reimbursed in full by US Borrower in accordance with the terms of
this Agreement and the related US LC Application (including any reimbursement by
means of concurrent US Loans or by the application of US LC Collateral), such US
Lender shall (in all circumstances and without set-off or counterclaim) pay to
US LC Issuer on demand, in immediately available funds at US LC Issuer's address
for notices hereunder, such US Lender's Percentage Share of such Matured US LC
Obligation (or any portion thereof which has not been reimbursed by US
Borrower). Each US Lender's obligation to pay US LC Issuer pursuant to the terms
of this subsection is irrevocable and unconditional. If any amount required to
be paid by any US Lender to US LC Issuer pursuant to this subsection is paid by
such US Lender to US LC Issuer within three Business Days after the date such
payment is due, US LC Issuer shall in addition to such amount be entitled to
recover from such US Lender, on demand, interest thereon calculated from such
due date at the Federal Funds Rate. If any amount required to be paid by any US
Lender to US LC Issuer pursuant to this subsection is not paid by such US Lender
to US LC Issuer within three Business Days after the date such payment is due,
US LC Issuer shall in addition to such amount be entitled to recover from such
US Lender, on demand, interest thereon calculated from such due date at the US
Base Rate plus the US Base Rate Margin.

     (d Distributions to Participants. Whenever US LC Issuer has in accordance
with this section received from any US Lender payment of such US Lender's
Percentage Share of any Matured US LC Obligation, if US LC Issuer thereafter
receives any payment of such Matured US LC Obligation or any payment of interest
thereon (whether directly from US Borrower or by application of US LC Collateral
or otherwise, and excluding only interest for any period prior to US LC Issuer's
demand that such US Lender make such payment of its Percentage Share), US LC
Issuer will distribute to such US Lender its Percentage Share of the amounts so
received by US LC Issuer; provided, however, that if any such payment received
by US LC Issuer must thereafter

                                       37

<PAGE>

be returned by US LC Issuer, such US Lender shall return to US LC Issuer the
portion thereof which US LC Issuer has previously distributed to it.

     (e  Calculations. A written advice setting forth in reasonable detail the
amounts owing under this section, submitted by US LC Issuer to US Borrower or
any US Lender from time to time, shall be conclusive, absent manifest error, as
to the amounts thereof.

     Section 2A.11. US Letter of Credit Fees. In consideration of US LC Issuer's
issuance of any US Letter of Credit, US Borrower agrees to pay (i) to
Administrative Agent for the account of each US Lender in proportion to its
Percentage Share, a US Letter of Credit fee equal to the US Letter of Credit Fee
Rate applicable each day times the face amount of such US Letter of Credit and
(ii) to such US LC Issuer for its own account, a letter of credit fronting fee
at a rate equal to one-eighth percent (.125%) per annum times the face amount of
such US Letter of Credit. Each such fee will be calculated on the face amount of
each US Letter of Credit outstanding on each day at the above applicable rates
and will be payable quarterly in arrears on the last day of each March, June,
September and December. In addition, US Borrower will pay to US LC Issuer a
minimum administrative issuance fee and such other fees and charges customarily
charged by the US LC Issuer in respect of any issuance, amendment or negotiation
of any US Letter of Credit in accordance with the US LC Issuer's published
schedule of such charges effective as of the date of such amendment or
negotiation.

     Section 2A.12. No Duty to Inquire.

     (a  Drafts and Demands. US LC Issuer is authorized and instructed to accept
and pay drafts and demands for payment under any US Letter of Credit without
requiring, and without responsibility for, any determination as to the existence
of any event giving rise to said draft, either at the time of acceptance or
payment or thereafter. US LC Issuer is under no duty to determine the proper
identity of anyone presenting such a draft or making such a demand (whether by
tested telex or otherwise) as the officer, representative or agent of any
beneficiary under any US Letter of Credit, and payment by US LC Issuer to any
such beneficiary when requested by any such purported officer, representative or
agent is hereby authorized and approved. US Borrower releases each Lender Party
from, and agrees to hold each Lender Party harmless and indemnified against, any
liability or claim in connection with or arising out of the subject matter of
this section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR
CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, provided only that no
Lender Party shall be entitled to indemnification for that portion, if any, of
any liability or claim which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment.

     (b  Extension of Maturity. If the maturity of any US Letter of Credit is
extended by its terms or by Law or governmental action, if any extension of the
maturity or time for presentation of drafts or any other modification of the
terms of any US Letter of Credit is made at the request of US Borrower, or if
the amount of any US Letter of Credit is increased at the request of US
Borrower, this Agreement shall be binding upon all Restricted Persons with
respect to such US Letter of Credit as so extended, increased or otherwise
modified, with respect

                                       38

<PAGE>

to drafts and property covered thereby, and with respect to any action
taken by US LC Issuer, US LC Issuer's correspondents, or any US Lender Party in
accordance with such extension, increase or other modification.

     (c  Transferees of US Letters of Credit. If any US Letter of Credit
provides that it is transferable, US LC Issuer shall have no duty to determine
the proper identity of anyone appearing as transferee of such US Letter of
Credit, nor shall US LC Issuer be charged with responsibility of any nature or
character for the validity or correctness of any transfer or successive
transfers, and payment by US LC Issuer to any purported transferee or
transferees as determined by US LC Issuer is hereby authorized and approved, and
US Borrower releases each US Lender Party from, and agrees to hold each US
Lender Party harmless and indemnified against, any liability or claim in
connection with or arising out of the foregoing, WHICH INDEMNITY SHALL APPLY
WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT
CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY
LENDER PARTY, provided only that no Lender Party shall be entitled to
indemnification for that portion, if any, of any liability or claim which is
proximately caused by its own individual gross negligence or willful misconduct,
as determined in a final judgment.

     Section 2A.13. US LC Collateral.

     (a  US LC Obligations in Excess of Commitment. If, after the making of all
mandatory prepayments required under Section 2A.7, the outstanding US LC
Obligations will exceed the US Commitment, then in addition to prepayment of the
entire principal balance of the US Loans US Borrower will immediately pay to US
LC Issuer an amount equal to such excess. US LC Issuer will hold such amount as
collateral security for the remaining US LC Obligations (all such amounts held
as collateral security for US LC Obligations being herein collectively called
"US LC Collateral") and the other Obligations, and such collateral may be
applied from time to time to any Matured US LC Obligations or any other
Obligations which are due and payable. Neither this subsection nor the following
subsection shall, however, limit or impair any rights which US LC Issuer may
have under any other document or agreement relating to any US Letter of Credit,
US LC Collateral or US LC Obligation, including any US LC Application, or any
rights which any US Lender Party may have to otherwise apply any payments by US
Borrower and any US LC Collateral under Section 3A.1.

     (b) Acceleration of US LC Obligations. If the Obligations or any part
thereof become immediately due and payable pursuant to Section 8.1 then, unless
all US Lenders otherwise specifically elect to the contrary (which election may
thereafter be retracted by any US Lender at any time), all US LC Obligations
shall become immediately due and payable without regard to whether or not actual
drawings or payments on the US Letters of Credit have occurred, and US Borrower
shall be obligated to pay to US LC Issuer immediately an amount equal to the
aggregate US LC Obligations which are then outstanding to be held as US LC
Collateral.

     (c) Investment of US LC Collateral. Pending application thereof, all US LC
Collateral shall be invested by US LC Issuer in such Cash Equivalents as US LC
Issuer may choose in its sole discretion. All interest on (and other proceeds
of) such Investments shall be

                                       39

<PAGE>

reinvested or applied to Matured US LC Obligations or the US Loans which are due
and payable. When all Obligations have been satisfied in full, including all US
LC Obligations, all US Letters of Credit have expired or been terminated, and
all of US Borrower's reimbursement obligations in connection therewith have been
satisfied in full, US LC Issuer shall release any remaining US LC Collateral. US
Borrower hereby assigns and grants to US LC Issuer for the benefit of US Lenders
a continuing security interest in all US LC Collateral paid by it to US LC
Issuer, all Investments purchased with such US LC Collateral, and all proceeds
thereof to secure its Matured US LC Obligations and its Obligations under this
Agreement, each US Note, and the other Loan Documents, and US Borrower agrees
that such US LC Collateral, Investments and proceeds shall be subject to all of
the terms and conditions of the Security Documents. US Borrower further agrees
that US LC Issuer shall have all of the rights and remedies of a secured party
under the Uniform Commercial Code as adopted in the State of New York with
respect to such security interest and that an Event of Default under this
Agreement shall constitute a default for purposes of such security interest.

     (d) Payment of US LC Collateral. When US Borrower is required to provide US
LC Collateral for any reason and fails to do so on the day when required, US LC
Issuer or Administrative Agent may without prior notice to US Borrower or any
other Restricted Person provide such US LC Collateral (whether by application of
proceeds of other Collateral, by transfers from other accounts maintained with
US LC Issuer, or otherwise) using any available funds of US Borrower or any
other Person also liable to make such payments, and US LC Issuer or
Administrative Agent will give notice thereof to US Borrower promptly after such
application or transfer. Any such amounts which are required to be provided as
US LC Collateral and which are not provided on the date required shall, for
purposes of each Security Document, be considered past due Obligations owing
hereunder, and US LC Issuer is hereby authorized to exercise its respective
rights under each Security Document to obtain such amounts.

     Section 2A.14. Hedging Contracts. All Hedging Contracts permitted hereunder
entered into with any one or more US Lenders or their Affiliates shall be deemed
to be Obligations and be secured by all Collateral; subject, however, to the
provisions of the Intercreditor Agreement.

     ARTICLE IIB - The Canadian Revolver Advances and Canadian Letters of Credit

                                       40

<PAGE>

     Section 2B.1. Canadian Revolver Advances. Subject to the terms and
conditions hereof, each Canadian Revolver Lender agrees to extend credit to
Canadian Revolver Borrower by advancing funds to Canadian Revolver Borrower
specified in a Borrowing Notice (herein called such Canadian Revolver Lender's
"Canadian Revolver Loans") and accepting and purchasing drafts of Bankers'
Acceptances issued under this Agreement by Canadian Revolver Borrower specified
in a Borrowing Notice (herein called such Canadian Revolver Lender's "Bankers'
Acceptances"; each Canadian Revolver Lender's Canadian Revolver Loans and
Bankers' Acceptances are herein collectively called such Canadian Revolver
Lender's "Canadian Revolver Advances") upon Canadian Revolver Borrower's request
from time to time during the Canadian Commitment Period, provided that (a)
subject to Sections 3.3, 3.4, and 3.6, all Canadian Revolver Lenders are
requested to make Canadian Revolver Advances of the same Type in accordance with
their respective Percentage Shares and as part of the same Borrowing, (b) after
giving effect to such Canadian Revolver Advances, the Canadian Revolver Facility
Usage does not exceed the Canadian Revolver Commitment determined as of the date
on which the requested Canadian Revolver Advances are to be made, and (c) after
giving effect to such Canadian Revolver Advances the Canadian Revolver Advances
by each Canadian Revolver Lender plus the existing Canadian LC Obligations of
such Canadian Revolver Lender does not exceed such Canadian Revolver Lender's
Canadian Revolver Commitment. The aggregate amount of all Canadian Revolver
Loans in any Borrowing must equal to C$500,000 or any higher integral multiple
of C$100,000. The obligation of Canadian Revolver Borrower to repay to each
Canadian Revolver Lender the aggregate amount of all Canadian Revolver Loans
made by such Canadian Revolver Lender to Canadian Revolver Borrower, together
with interest accruing in connection therewith, shall be evidenced by a single
promissory note (herein called such Canadian Revolver Lender's "Canadian
Revolver Note") made by Canadian Revolver Borrower payable to the order of such
Canadian Revolver Lender in the form of Exhibit A-2 with appropriate insertions.
The amount of principal owing on any Canadian Revolver Lender's Canadian
Revolver Note at any given time shall be the aggregate amount of all Canadian
Revolver Loans theretofore made by such Canadian Revolver Lender minus all
payments of principal theretofore received by such Canadian Revolver Lender on
such Canadian Revolver Note. Interest on each Canadian Revolver Note shall
accrue and be due and payable as provided herein and therein. Each Canadian
Revolver Lender's Canadian Revolver Note shall be due and payable as provided
herein and therein and shall be due and payable in full on the Canadian Revolver
Maturity Date. Subject to the terms and conditions of this Agreement, Canadian
Revolver Borrower may borrow, repay, and reborrow under this Section 2B.1.
Canadian Revolver Borrower may have no more than seven Borrowings of BA's
collectively outstanding at any time. All payments of principal and interest on
the Canadian Revolver Loans shall be made in the currency in which such
corresponding Canadian Revolver Loan was funded. All Canadian Revolver Loans
shall be made in Canadian Dollars, or, upon the written request of Canadian
Revolver Borrower, in Dollars.

     Section 2B.2. Requests for New Canadian Revolver Advances. The Canadian
Revolver Borrower must give to Canadian Administration Agent written notice (or
telephonic notice promptly confirmed in writing) of any requested Borrowing of
Canadian Revolver Loans to be funded by Canadian Revolver Lenders and any
requested Borrowing by way of Bankers' Acceptances. Each such notice constitutes
a "Borrowing Notice" hereunder and must:

                                       41

<PAGE>

          (a) specify (i) the aggregate amount of any such Borrowing of new
     Canadian Revolver Prime Rate Loans and the date on which such Canadian
     Revolver Prime Rate Loans are to be advanced, or (ii) the aggregate amount
     of any such Borrowing by way of Bankers' Acceptances (subject to Section
     2B.2(f)), and the date on which such Bankers' Acceptances are to be
     accepted and the maturity of such Bankers' Acceptances; and

          (b) be received by Canadian Administration Agent not later than 10:00
     a.m., Toronto, Ontario time, on (i) the day on which any such Canadian
     Revolver Prime Rate Loans are to be made, or (ii) the third Business Day
     before such Bankers' Acceptances are to be issued.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B-2, duly completed. Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by Canadian Revolver Borrower as to the matters
which are required to be set out in such written confirmation. Upon receipt of
any such Borrowing Notice, Canadian Administration Agent shall give each
Canadian Revolver Lender prompt notice of the terms thereof. If all conditions
precedent to such new Canadian Revolver Advances have been met, each Canadian
Revolver Lender will on the date requested promptly remit to Canadian
Administration Agent at Canadian Administration Agent's office in Toronto,
Ontario the amount of such Canadian Revolver Lender's new Canadian Revolver
Advance in immediately available funds, and upon receipt of such funds, unless
to its actual knowledge any conditions precedent to such Canadian Revolver
Advances have been neither met nor waived as provided herein, Canadian
Administration Agent shall promptly make such Canadian Revolver Advances
available to Canadian Revolver Borrower or each Canadian Lender will accept
drafts of Bankers' Acceptances on the date requested in accordance with Sections
2B.1 through 2B.3. Unless Canadian Administration Agent shall have received
prompt notice from a Canadian Revolver Lender that such Canadian Revolver Lender
will not make available to Canadian Administration Agent such Canadian Revolver
Lender's new Canadian Revolver Advance, Canadian Administration Agent may in its
discretion assume that such Canadian Revolver Lender has made such Canadian
Revolver Advance available to Canadian Administration Agent in accordance with
this section, and Canadian Administration Agent may if it chooses, in reliance
upon such assumption, make such Canadian Revolver Advance available to Canadian
Revolver Borrower. If and to the extent such Canadian Revolver Lender shall not
so make its new Canadian Revolver Advance available to Canadian Administration
Agent, such Canadian Revolver Lender and Canadian Revolver Borrower severally
agree to pay or repay to Canadian Administration Agent within three days after
demand the amount of such Canadian Revolver Advance together with interest
thereon, for each day from the date such amount was made available to the
applicable Canadian Borrower until the date such amount is paid or repaid to
Canadian Administration Agent, with interest at (i) the Canadian Revolver Prime
Rate, if such Canadian Revolver Lender is making such payment and (ii) the
interest rate applicable at the time to the other new Canadian Revolver Advances
made on such date, if Canadian Borrower is making such repayment. If neither
such Canadian Revolver Lender nor Canadian Revolver Borrower pays or repays to
Canadian Administration Agent such amount within such three-day period, Canadian
Administration Agent shall be entitled to recover from Canadian Revolver
Borrower, on demand in lieu of the interest provided for in the preceding
sentence, interest thereon at the Default Rate, calculated from the

                                       42

<PAGE>

date such amount was made available to Canadian Revolver Borrower. The failure
of any Canadian Revolver Lender to make any new Canadian Revolver Advance to be
made by it hereunder shall not relieve any other Canadian Revolver Lender of its
obligation hereunder, if any, to make its new Canadian Revolver Advance, but no
Canadian Revolver Lender shall be responsible for the failure of any other
Canadian Revolver Lender to make any new Canadian Revolver Advance to be made by
such other Canadian Revolver Lender. All Borrowings of Canadian Revolver Loans
shall be advanced to Canadian Revolver Borrower in Canadian Dollars, or, upon
the written request of Canadian Revolver Borrower, in Dollars in an amount equal
to the Dollar Equivalent of such requested Canadian Revolver Loan.

     Section 2B.3. Continuations and Conversions of Existing Canadian Revolver
Advances. Subject to the terms of Section 2B.9 with respect to Bankers'
Acceptances, Canadian Revolver Borrower may make the following elections with
respect to Canadian Revolver Advances already outstanding: (i) to Convert any
Type of Canadian Revolver Advance to any other Type of Canadian Revolver
Advance, provided that any such Conversion of a Bankers' Acceptance must be made
on the date of maturity thereof; and (ii) to rollover any existing Bankers'
Acceptance by designating the new maturity date applicable thereto. In making
such elections, Canadian Revolver Borrower may combine existing Canadian
Revolver Advances made pursuant to separate Borrowings into one new Borrowing or
divide existing Canadian Revolver Advances made pursuant to one Borrowing into
separate new Borrowings, provided that Canadian Revolver Borrower may have no
more than seven Borrowings of BA's outstanding at any time. To make any such
election, Canadian Revolver Borrower must give to Canadian Administration Agent
written notice (or telephonic notice promptly confirmed in writing) of any such
Conversion or Continuation of existing Canadian Revolver Advances, with a
separate notice given for each new Borrowing. Each such notice constitutes a
"Continuation/Conversion Notice" hereunder and must:

          (a) specify the existing Canadian Revolver Advances which are to be
     Continued or Converted;

          (b) specify (i) the aggregate amount of any Borrowing of Canadian
     Revolver Prime Rate Loans into which such existing Canadian Revolver
     Advances are to be Continued or Converted and the date on which such
     Continuation or Conversion is to occur, or (ii) the amount of any Borrowing
     of Bankers' Acceptances into which such existing Canadian Revolver Advances
     are to be Continued or Converted, the date on which such Continuation or
     Conversion is to occur, and the maturity of such Bankers' Acceptances; and

          (c) be received by Canadian Administration Agent not later than 10:00
     a.m., Toronto, Ontario time, on (i) the day on which any such Continuation
     or Conversion to Canadian Revolver Prime Rate Loans is to occur, or (ii) on
     the third Business Day preceding the day on which any such Continuation or
     Conversion to Bankers' Acceptances is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit B-2, duly
completed. Each such

                                       43

<PAGE>

telephonic request shall be deemed a representation, warranty, acknowledgment
and agreement by Canadian Revolver Borrower as to the matters which are required
to be set out in such written confirmation. Upon receipt of any such
Continuation/Conversion Notice, Canadian Revolver Agent shall give each Canadian
Revolver Lender prompt notice of the terms thereof. Each Continuation/Conversion
Notice shall be irrevocable and binding on Canadian Revolver Borrower. During
the continuance of any Default, Canadian Revolver Borrower may not make any
election to Convert existing Canadian Revolver Advances into Bankers'
Acceptances or to rollover existing Bankers' Acceptances into new Bankers'
Acceptances. If (due to the existence of a Default or for any other reason)
Canadian Revolver Borrower fails to timely and properly give any
Continuation/Conversion Notice with respect to a Borrowing of existing Bankers'
Acceptances at least three days prior to the maturity of the Bankers'
Acceptance, such Bankers' Acceptances, to the extent not prepaid at the end of
such Interest Period, shall automatically be Converted into Canadian Revolver
Prime Rate Loans at the end of such Interest Period. No new funds shall be
repaid by Canadian Revolver Borrower or advanced by any Canadian Revolver Lender
in connection with any Continuation or Conversion of existing Canadian Revolver
Advances pursuant to this section, and no such Continuation or Conversion shall
be deemed to be a new advance of funds for any purpose; such Continuations and
Conversions merely constitute a change in the interest rate applicable to
already outstanding Loans.

     Section 2B.4. Repayments of Canadian Revolver Loans.

     (a) Mandatory Prepayments. Except to the extent permitted by Section
2B.4(c), if the aggregate principal amount of the outstanding Canadian Revolver
Facility Usage ever exceeds the Canadian Revolver Commitment, Canadian Revolver
Borrower shall immediately on demand prepay the principal of the Canadian
Revolver Advances in an amount at least equal to such excess. Each prepayment of
principal under this section shall be accompanied by all interest then accrued
and unpaid on the principal so prepaid. Any principal or interest prepaid
pursuant to this section shall be in addition to, and not in lieu of, all
payments otherwise required to be paid under the Loan Documents at the time of
such prepayment. No BA may be prepaid as a result of the operation of this
Section 2B.4(b); provided, however, that any such excess required to be paid
under this Section 2B.4(b) and not otherwise applicable to Canadian Revolver
Loans will be paid to Canadian Administration Agent and held in accordance with
Section 2B.11.

     (b) Currency Fluctuations. Notwithstanding any other provision of this
Agreement, Canadian Administration Agent shall have the right to calculate the
outstanding Canadian Revolver Facility Usage for all purposes including making a
determination from time to time of the available undrawn portion of the Canadian
Revolver Commitment. If following such calculation, Canadian Administration
Agent determines that the Canadian Revolver Facility Usage is greater than 105%
of the Canadian Revolver Commitment, then Canadian Administration Agent shall so
advise Canadian Revolver Borrower and Canadian Revolver Borrower shall repay, on
the earlier of five Business Days after such advice and the next applicable
Interest Payment Date immediately following such advice, an amount sufficient to
eliminate such excess, together with all accrued interest on the amount so paid.
No BA may be prepaid as a result of the operation of this Section 2B.4(c);
provided, however, that any such excess required to be paid under this Section
2B.4(c) and not otherwise applicable to Canadian

                                       44

<PAGE>

Revolver Loans will be paid to Canadian Administration Agent and held in
accordance with Section 2B.11.

     (c) Optional Prepayments. Canadian Revolver Borrower may, upon five
Business Days' notice to Canadian Administration Agent (and Canadian
Administration Agent will promptly give notice to the other Canadian Revolver
Lenders) from time to time and without premium or penalty prepay the Canadian
Revolver Loans, in whole or in part, so long as the aggregate amounts of all
partial prepayments of principal on the Canadian Revolver Loans equals C$100,000
or any higher integral multiple of C$100,000. Each prepayment of principal under
this section shall be accompanied by all interest then accrued and unpaid on the
principal so prepaid. Any principal or interest prepaid pursuant to this section
shall be in addition to, and not in lieu of, all payments otherwise required to
be paid under the Loan Documents at the time of such prepayment. No BA may be
prepaid hereunder except in accordance with Section 2B.11.

     Section 2B.5. Interest Rates and Fees.

     (a) Interest Rates. Each Canadian Revolver Loan shall bear interest as
follows: (i) unless the Default Rate shall apply, each Canadian Revolver Prime
Rate Loan shall bear interest on each day outstanding at the Canadian Revolver
Prime Rate plus the Canadian Revolver Prime Rate Margin in effect on such day,
and (ii) during a Default Rate Period, all Canadian Revolver Loans shall bear
interest on each day outstanding at the applicable Default Rate. If an Event of
Default based upon Section 8.1(a), Section 8.1(b) or, with respect to Canadian
Revolver Borrower, based upon Section 8.1(i)(i), (i)(ii) or (i)(iii) exists and
the Canadian Revolver Loans are not bearing interest at the Default Rate, the
past due principal and past due interest shall bear interest on each day
outstanding at the applicable Default Rate. The interest rate shall change
whenever the applicable Canadian Revolver Prime Rate or the Canadian Revolver
Prime Rate Margin changes. In no event shall the interest rate on any Canadian
Revolver Loan exceed the such rates as set out in or calculated pursuant to
Section 10.10.

     (b) Commitment Fees. In consideration of each Canadian Revolver Lender's
commitment to make Canadian Revolver Advances, Canadian Revolver Borrower will
pay to Canadian Administration Agent for the account of each Canadian Revolver
Lender a commitment fee determined on a daily basis equal to the Canadian
Revolver Commitment Fee Rate in effect on such day times such Canadian Revolver
Lender's Percentage Share of the unused portion of the Canadian Revolver
Commitment on each day during the Canadian Commitment Period, determined for
each such day by deducting from the amount of the Canadian Revolver Commitment
at the end of such day the Canadian Revolver Facility Usage. This commitment fee
shall be due and payable in arrears on the last day of each Fiscal Quarter and
at the end of the Canadian Commitment Period. Canadian Revolver Borrower shall
have the right from time to time to permanently reduce the Canadian Revolver
Commitment, provided that (i) notice of such reduction is given not less than 2
Business Days prior to such reduction, (ii) the resulting Canadian Revolver
Commitment is not less than the Canadian Revolver Facility Usage and (iii) each
partial reduction shall be in an amount at least equal to C$500,000 and in
multiples of C$100,000 in excess thereof.

                                       45

<PAGE>

     (c) Stamping Fees. In consideration of each Canadian Revolver Lender's
commitment to accept or participate in Bankers' Acceptances under this
Agreement, Canadian Revolver Borrower will pay to Canadian Administration Agent
for the account of such Canadian Revolver Lender the Stamping Fee Rate
multiplied by the face amount of each Bankers' Acceptance accepted by such
Canadian Revolver Lender under this Agreement calculated for the number of days
in the term of such Bankers' Acceptance. Such fee shall be due and payable on
the date on which such Bankers' Acceptances are accepted and shall be deducted
from the Discount Proceeds paid to Canadian Revolver Borrower. Such fee shall be
non-refundable, notwithstanding any reduction in the Stamping Fee Rate during
the term of such Bankers' Acceptances.

     (d) Canadian Administration Agent's Fees. In addition to all other amounts
due to Canadian Administration Agent under the Loan Documents, Canadian Revolver
Borrower will pay fees to Canadian Administration Agent as described in the
agency fee agreement between Canadian Administration Agent and Canadian Revolver
Borrower.

     Section 2B.6. Use of Proceeds. Canadian Revolver Borrower shall use all
Canadian Revolver Advances (i) to finance its capital expenditures, (ii) to pay
reimbursement obligations of Canadian Letters of Credit, and (iii) to provide
working capital for operations and for other general business purposes. Canadian
Revolver Borrower shall use all Canadian Letters of Credit for its and its
Subsidiaries' general corporate purposes (but not to pay distributions to
partners of Restricted Persons), including in relation to the purchase or
exchange by Canadian Revolver Borrower of Petroleum Products. In no event shall
the funds from any Canadian Revolver Loan, or any Canadian Letter of Credit, or
any Banker's Acceptance be used directly or indirectly by any Person for
personal, family, household or agricultural purposes or for the purpose, whether
immediate, incidental or ultimate, of purchasing, acquiring or carrying any
"margin stock" (as such term is defined in Regulation U promulgated by the Board
of Governors of the Federal Reserve System) or to extend credit to others
directly or indirectly for the purpose of purchasing or carrying any such margin
stock. Canadian Revolver Borrower represents and warrants that it is not engaged
principally, or as one of its important activities, in the business of extending
credit to others for the purpose of purchasing or carrying such margin stock.

     Section 2B.7. Creation of Bankers' Acceptances. Upon receipt of a Borrowing
Notice requesting a Borrowing by way of Bankers' Acceptances, and subject to the
provisions of this Agreement, each Canadian Revolver Lender shall accept, in
accordance with its Percentage Share of the requested Borrowing from time to
time such Bankers' Acceptances as Canadian Revolver Borrower shall request
provided that:

          (a) Bankers' Acceptances shall be issued on a Business Day;

          (b) each Bankers' Acceptance shall have a term of one, two, three or
     six months (excluding days of grace), as selected by Canadian Revolver
     Borrower in the relevant Borrowing Notice provided that each Bankers'
     Acceptance shall mature on a Business Day;

                                       46

<PAGE>

          (c) the face amount of each Bankers' Acceptance shall be not less than
     C$500,000 and in multiples of C$100,000 for any amounts in excess thereof;
     and

          (d) each Bankers' Acceptance shall be in a form acceptable to the
     Canadian Administration Agent.

     Section 2B.8.  Terms of Acceptance by the Canadian Revolver Lenders.

     (a)  Delivery and Payment. Subject to Sections 2B.3 and 2B.4 and only if a
valid appointment pursuant to Section 2B.8(d) is not in place, Canadian Revolver
Borrower shall pre-sign and deliver to each Canadian Revolver Lender bankers'
acceptance drafts in sufficient quantity to meet Canadian Revolver Borrower's
requirements for anticipated Borrowings by way of Bankers' Acceptances. Canadian
Revolver Borrower shall, at its option, provide for payment to Canadian
Administration Agent for the benefit of Canadian Revolver Lenders of each
Bankers' Acceptance on the date on which a Bankers' Acceptance matures, either
by payment of the full face amount thereof or through utilization of a
Conversion to another Type of Borrowing in accordance with this Agreement, or
through a combination thereof. Canadian Revolver Borrower waives presentment for
payment of Bankers' Acceptances by Canadian Revolver Lenders and shall not claim
from Canadian Revolver Lenders any days of grace for the payment at maturity of
Bankers' Acceptances. Any amount owing by Canadian Revolver Borrower in respect
of any Bankers' Acceptance which is not paid in accordance with the foregoing,
shall, as and from the date on which such Bankers' Acceptance matures, be deemed
to be outstanding hereunder as a Canadian Revolver Prime Rate Loan.

     (b)  No Liability. Canadian Administration Agent and Canadian Revolver
Lenders shall not be liable for any damage, loss or improper use of any bankers'
acceptance draft endorsed in blank except for any loss arising by reason of
Canadian Administration Agent or a Canadian Revolver Lender failing to use the
same standard of care in the custody of such bankers' acceptance drafts as
Canadian Administration Agent or such Canadian Revolver Lender use in the
custody of their own property of a similar nature.

     (c)  Bankers' Acceptances Purchased by Canadian Revolver Lenders. Each
Canadian Revolver Lender shall purchase Bankers' Acceptances accepted by it for
an amount equal to the Discount Proceeds.

     (d)  Power of Attorney. To facilitate the procedures contemplated in this
Agreement, Canadian Revolver Borrower appoints each Canadian Revolver Lender
from time to time as the attorney-in-fact of Canadian Revolver Borrower to
execute, endorse and deliver on behalf of Canadian Revolver Borrower drafts or
depository bills in the form or forms prescribed by such Canadian Revolver
Lender for Bankers' Acceptances denominated in Canadian Dollars. Each Bankers'
Acceptance executed and delivered by a Canadian Revolver Lender on behalf of
Canadian Revolver Borrower shall be as binding upon such Canadian Revolver
Borrower as if it had been executed and delivered by a duly authorized officer
of such Canadian Revolver Borrower. The foregoing appointment shall cease to be
effective, in respect of any Canadian Revolver Lender regarding Canadian
Revolver Borrower, three Business Days following receipt by such Canadian
Revolver Lender of a written notice from Canadian Revolver Borrower

                                       47

<PAGE>

revoking such appointment (which notice shall be copied to the Canadian
Administration Agent); provided that any such revocation shall not affect
Bankers' Acceptances previously executed and delivered by such Canadian Revolver
Lender pursuant to such appointment.

     (e)  Pro-Rata Treatment of Canadian Revolver Advances.

          (i) Each Canadian Revolver Advance shall be made available by each
     Canadian Revolver Lender and all repayments and reductions in respect
     thereof shall be made and applied in a manner so that the Canadian Revolver
     Advances outstanding hereunder to each Canadian Revolver Lender will, to
     the extent possible, thereafter be pro rata in accordance with such
     Canadian Revolver Lender's Percentage Share. The Canadian Administration
     Agent is authorized by Canadian Revolver Borrower and each Canadian
     Revolver Lender to determine, in its sole and unfettered discretion, the
     portion of each Canadian Revolver Advance and each Type of Canadian
     Revolver Advance to be made available by each Canadian Revolver Lender and
     the application of repayments and reductions of Canadian Revolver Advances
     to give effect to the provisions of this Section, provided that no Canadian
     Revolver Lender shall, as a result of any such determination, have a
     Percentage Share of the Canadian Revolver Advances which is in excess of
     its Percentage Share of the Canadian Revolver Commitment.

          (ii) In the event it is not practicable to allocate Bankers'
     Acceptances to each Canadian Revolver Lender such that the aggregate amount
     of Bankers' Acceptances required to be purchased by such Canadian Revolver
     Lender hereunder is in a whole multiple of C$100,000, the Canadian
     Administration Agent is authorized by each Canadian Borrower and each
     Canadian Revolver Lender to make such allocation as the Canadian
     Administration Agent determines in its sole and unfettered discretion may
     be equitable in the circumstances and, if the aggregate amount of such
     Bankers' Acceptances is not a whole multiple of C$100,000, then the
     Canadian Administration Agent may allocate (on a basis considered by it to
     be equitable) the excess of such Canadian Revolver Advance over the next
     lowest whole multiple of C$100,000 to one Canadian Revolver Lender, which
     shall purchase a Bankers' Acceptance with a face amount equal to the excess
     and having the same term as the corresponding Bankers' Acceptances. In no
     event shall the portion of the outstanding Borrowings by way of Bankers'
     Acceptances of a Canadian Revolver Lender exceed such Canadian Revolver
     Lenders' Percentage Share of the aggregate Borrowings by way of Bankers'
     Acceptances by more than C$100,000 as a result of such exercise of
     discretion by the Canadian Administration Agent.

     (f)  BA Equivalent Advances. Each Canadian Revolver Lender may, in lieu of
accepting a BA on the date of any Borrowing, make a BA Equivalent Advance. The
amount of each BA Equivalent Advance shall be equal to the Discount Proceeds
(with reference to the applicable BA Discount Rate) which would be realized from
a hypothetical sale of those BAs which, but for this subsection, would have been
sold to such Canadian Revolver Lender. If such Canadian Revolver Lender does not
otherwise have a BA Discount Rate applicable to it, the applicable BA Discount
Rate will be calculated as though such Canadian Revolver Lender was listed on
Schedule II of the Bank Act (Canada). Any BA Equivalent Advance shall be made on
the relevant date of any Borrowing, and shall remain outstanding for the term of
the

                                       48

<PAGE>

corresponding BA. On the maturity date of the corresponding BA, such BA
Equivalent Advance shall be repaid in an amount equal to the face amount of a
draft that would have been accepted by such Canadian Revolver Lender if such
Canadian Revolver Lender had accepted and purchase a BA hereunder. Each BA
Equivalent Advance made pursuant to this subsection shall be deemed to be a BA
accepted and purchased by such Canadian Revolver Lender pursuant to the terms
hereof, and except in this subsection, any reference to a BA shall include such
BA Equivalent Advance.

     Section 2B.9. General Procedures for Bankers' Acceptances.

     (a) Continuations. In the case of a Continuation of maturing Bankers'
Acceptances, each Canadian Revolver Lender in order to satisfy the continuing
liability of Canadian Revolver Borrower to the Canadian Revolver Lender for the
face amount of the maturing Bankers' Acceptances, shall retain for its own
account the Net Proceeds of each new Bankers' Acceptance issued by it in
connection with such Continuation; and Canadian Revolver Borrower shall, on the
maturity date of the maturing Bankers' Acceptances, pay to Canadian
Administration Agent for the benefit of Canadian Revolver Lenders an amount
equal to the difference between the face amount of the maturing Bankers'
Acceptances and the aggregate Net Proceeds of the new Bankers' Acceptances.

     (b) Conversion from Canadian Revolver Prime Rate Loans. In the case of a
Conversion from a Borrowing of Canadian Revolver Prime Rate Loans into a
Borrowing by way of Bankers' Acceptances to be accepted by a Canadian Revolver
Lender pursuant to Sections 2B.1, 2B.2 and 2B.3, such Canadian Revolver Lender,
in order to satisfy the continuing liability of Canadian Revolver Borrower to it
for the principal amount of the Canadian Revolver Prime Rate Loans being
converted, shall retain for its own account the Discount Proceeds of each new
Bankers' Acceptance issued by it in connection with such Conversion; and
Canadian Revolver Borrower shall, on the date of issuance of the Bankers'
Acceptances, pay to Canadian Administration Agent for the benefit of Canadian
Revolver Lenders an amount equal to the difference between the aggregate
principal amount of the Canadian Revolver Prime Rate Loans being converted owing
to the Canadian Revolver Lenders and the aggregate Discount Proceeds of such
Bankers' Acceptances.

     (c) Authorization. Canadian Revolver Borrower hereby authorizes each
Canadian Revolver Lender to complete, stamp, hold, sell, rediscount or otherwise
dispose of all Bankers' Acceptances accepted by it pursuant to this Section in
accordance with the instructions provided by Canadian Revolver Borrower pursuant
to Section 2B.3, as applicable.

     (d) Depository Notes. The parties agree that in the administering of
Bankers' Acceptances, each Canadian Revolver Lender may avail itself of the debt
clearing services offered by a clearing house for depository notes pursuant to
the Depository Bills and Notes Act (Canada) and that the procedures set forth in
Article II be deemed amended to the extent necessary to comply with the
requirements of such debt clearing services.

     Section 2B.10. Execution of Bankers' Acceptances. The signatures of any
authorized signatory on Bankers' Acceptances which are authorized and requested
hereunder by the

                                       49

<PAGE>

Canadian Revolver Borrower may, at the option of Canadian Revolver Borrower, be
reproduced in facsimile and such Bankers' Acceptances bearing such facsimile
signatures shall be binding on Canadian Revolver Borrower as if they had been
manually signed by such authorized signatory. Notwithstanding that any person
whose signature appears on any Bankers' Acceptance as a signatory may no longer
be an authorized signatory of Canadian Revolver Borrower at the date of issuance
of a Bankers' Acceptance, and notwithstanding that the signature affixed may be
a reproduction only, such signature shall, unless prior to its use the Canadian
Revolver Borrower has notified the Canadian Administration Agent in writing to
contrary, nevertheless be valid and sufficient for all purposes as if such
authority had remained in force at the time of such issuance and as if such
signature had been manually applied, and any such Bankers' Acceptance so signed
shall be binding on Canadian Revolver Borrower.

     Section 2B.11. Escrowed Funds. Upon the occurrence of an Event of Default
and an acceleration of the Obligations under Section 8.1, or if, after the
making of a prepayment as permitted or required under Section 2B.4, the
outstanding Bankers' Acceptances will exceed the Canadian Revolver Commitment,
Canadian Revolver Borrower shall forthwith pay to Canadian Administration Agent
for deposit into an escrow account maintained by and in the name of Canadian
Administration Agent for the benefit of Canadian Revolver Lenders in accordance
with their Percentage Shares an amount equal to the Canadian Revolver Lenders'
maximum potential liability (as determined by Canadian Administration Agent)
under then outstanding Bankers' Acceptances or the amount by which the then
outstanding Bankers' Acceptances exceed the Canadian Revolver Commitment, as the
case may be (the "Escrow Funds"). The Escrow Funds shall be held by Canadian
Administration Agent for set-off against such outstanding Bankers' Acceptances
or such excess, as the case may be, or future Canadian Obligations, and pending
such application shall bear interest at the rate declared by Canadian
Administration Agent from time to time as that payable by it in respect of
deposits for such amount and for such period relative to the maturity date of
such Bankers' Acceptances, as applicable. If such Event of Default is either
waived or cured in compliance with the terms of this Agreement, or the
outstanding Bankers' Acceptances no longer exceed the Canadian Revolver
Commitment, as the case may be, then the Escrow Funds, together with any accrued
interest to the date of release, shall be forthwith released to Canadian
Revolver Borrower.

     Section 2B.12. Canadian Letters of Credit. Subject to the terms and
conditions hereof, Canadian Revolver Borrower may during the Canadian Commitment
Period request Canadian LC Issuer to issue, amend, or extend the expiration date
of, one or more Canadian Letters of Credit denominated in either Canadian
Dollars or Dollars, provided that, after taking such Canadian Letter of Credit
into account:

          (a) the Canadian Facility Usage does not exceed the Canadian Revolver
     Commitment at such time;

          (b) the aggregate amount of Canadian LC Obligations at such time does
     not exceed the Dollar Equivalent of $5,000,000;

                                       50

<PAGE>

          (c) the expiration date of such Canadian Letter of Credit is prior to
     the earlier of (i) one (1) year after the date of issuance of such Canadian
     Letter of Credit or (ii) the end of the Canadian Commitment Period;

          (d) such Canadian Letter of Credit is to be used for general corporate
     purposes of Canadian Revolver Borrower or any of its Subsidiaries and is
     not directly or indirectly used to assure payment of or otherwise support
     any Indebtedness of any Person, except Indebtedness of a Restricted Person;

          (e) the issuance of such Canadian Letter of Credit will be in
     compliance with all applicable governmental restrictions, policies, and
     guidelines and will not subject Canadian LC Issuer to any cost which is not
     reimbursable under Article III;

          (f) the form and terms of such Canadian Letter of Credit are
     acceptable to Canadian LC Issuer in its sole and absolute discretion; and

          (g) all other conditions in this Agreement to the issuance of such
     Canadian Letter of Credit have been satisfied.

Canadian LC Issuer will honor any such request if the foregoing conditions (a)
through (g) (in the following Section 2B.13 called the "Canadian LC Conditions")
have been met as of the date of issuance, amendment, or extension of the
expiration, of such Canadian Letter of Credit.

     Section 2B.13. Requesting Canadian Letters of Credit. Canadian Revolver
Borrower must make written application for any Canadian Letter of Credit at
least two Business Days before the date on which Canadian Revolver Borrower
desires for Canadian LC Issuer to issue such Canadian Letter of Credit. By
making any such written application, unless otherwise expressly stated therein,
Canadian Revolver Borrower shall be deemed to have represented and warranted
that the Canadian LC Conditions described in Section 2B.12 will be met as of the
date of issuance of such Canadian Letter of Credit. Each such written
application for a Canadian Letter of Credit must be made in writing in the form
and substance of Exhibit G-2, the terms and provisions of which are hereby
incorporated herein by reference (or in such other form as may mutually be
agreed upon by Canadian LC Issuer and Canadian Revolver Borrower). If all
Canadian LC Conditions for a Canadian Letter of Credit have been met as
described in Section 2B.12 on any Business Day before 11:00 a.m., Toronto,
Ontario time, Canadian LC Issuer will issue such Canadian Letter of Credit on
the same Business Day at Canadian LC Issuer's office in Toronto, Ontario. If the
Canadian LC Conditions are met as described in Section 2B.12 on any Business Day
on or after 11:00 a.m., Toronto, Ontario time, Canadian LC Issuer will issue
such Canadian Letter of Credit on the next succeeding Business Day at Canadian
LC Issuer's office in Toronto, Ontario. If any provisions of any Canadian LC
Application conflict with any provisions of this Agreement, the provisions of
this Agreement shall govern and control.

     Section 2B.14. Reimbursement and Participations.

     (a)  Reimbursement by Canadian Revolver Borrower. Each Matured Canadian LC
Obligation shall constitute a loan by Canadian LC Issuer to Canadian Revolver
Borrower.

                                       51

<PAGE>

Canadian Revolver Borrower promises to pay to Canadian LC Issuer, or to Canadian
LC Issuer's order, on demand, the full amount of each Matured Canadian LC
Obligation, together with interest thereon (i) at the Canadian Revolver Prime
Rate to and including the second Business Day after the Matured Canadian LC
Obligation is incurred and (ii) at the Default Rate on each day thereafter.

     (b) Canadian Letter of Credit Advances. If the beneficiary of any Canadian
Letter of Credit makes a draft or other demand for payment thereunder then
Canadian Revolver Borrower may, during the interval between the making thereof
and the honoring thereof by Canadian LC Issuer, request Canadian Revolver
Lenders to make Canadian Revolver Loans to Canadian Revolver Borrower in the
amount of such draft or demand, which Canadian Revolver Loans shall be made
concurrently with Canadian LC Issuer's payment of such draft or demand and shall
be immediately used by Canadian LC Issuer to repay the amount of the resulting
Matured Canadian LC Obligation. Such a request by Canadian Revolver Borrower
shall be made in compliance with all of the provisions hereof, provided that for
the purposes of the first sentence of Section 2B.1, the amount of such Canadian
Revolver Loans shall be considered, but the amount of the Matured Canadian LC
Obligation to be concurrently paid by such Canadian Revolver Loans shall not be
considered.

     (c) Participation by Canadian Lenders. Canadian LC Issuer irrevocably
agrees to grant and hereby grants to each Canadian Revolver Lender, and -- to
induce Canadian LC Issuer to issue Canadian Letters of Credit hereunder -- each
Canadian Revolver Lender irrevocably agrees to accept and purchase and hereby
accepts and purchases from Canadian LC Issuer, on the terms and conditions
hereinafter stated and for such Canadian Revolver Lender's own account and risk
an undivided interest equal to such Canadian Revolver Lender's Percentage Share
of Canadian LC Issuer's obligations and rights under each Canadian Letter of
Credit issued hereunder and the amount of each Matured Canadian LC Obligation
paid by Canadian LC Issuer thereunder. Each Canadian Revolver Lender
unconditionally and irrevocably agrees with Canadian LC Issuer that, if a
Matured Canadian LC Obligation is paid under any Canadian Letter of Credit for
which Canadian LC Issuer is not reimbursed in full by Canadian Revolver Borrower
in accordance with the terms of this Agreement and the related Canadian LC
Application (including any reimbursement by means of concurrent Canadian
Revolver Loans or by the application of Canadian LC Collateral), such Canadian
Revolver Lender shall (in all circumstances and without set-off or counterclaim)
pay to Canadian LC Issuer on demand, in immediately available funds at Canadian
LC Issuer's address for notices hereunder, such Canadian Revolver Lender's
Percentage Share of such Matured Canadian LC Obligation (or any portion thereof
which has not been reimbursed by Canadian Revolver Borrower). Each Canadian
Revolver Lender's obligation to pay Canadian LC Issuer pursuant to the terms of
this subsection is irrevocable and unconditional. If any amount required to be
paid by any Canadian Revolver Lender to Canadian LC Issuer pursuant to this
subsection is paid by such Canadian Revolver Lender to Canadian LC Issuer within
three Business Days after the date such payment is due, Canadian LC Issuer shall
in addition to such amount be entitled to recover from such Canadian Revolver
Lender, on demand, interest thereon calculated from such due date at the "Bank
Rate" as set by the Bank of Canada, as quoted on Reuters page BOCFAD. If any
amount required to be paid by any Canadian Revolver Lender to Canadian LC Issuer
pursuant to this subsection is not paid by such Canadian Revolver Lender to
Canadian LC Issuer within three Business Days after

                                       52

<PAGE>

the date such payment is due, Canadian LC Issuer shall in addition to such
amount be entitled to recover from such Canadian Revolver Lender, on demand,
interest thereon calculated from such due date at the Canadian Revolver Prime
Rate.

     (d)  Distributions to Participants. Whenever Canadian LC Issuer has in
accordance with this section received from any Canadian Revolver Lender payment
of such Canadian Revolver Lender's Percentage Share of any Matured Canadian LC
Obligation, if Canadian LC Issuer thereafter receives any payment of such
Matured Canadian LC Obligation or any payment of interest thereon (whether
directly from Canadian Revolver Borrower or by application of Canadian LC
Collateral or otherwise, and excluding only interest for any period prior to
Canadian LC Issuer's demand that such Canadian Revolver Lender make such payment
of its Percentage Share), Canadian LC Issuer will distribute to such Canadian
Revolver Lender its Percentage Share of the amounts so received by Canadian LC
Issuer; provided, however, that if any such payment received by Canadian LC
Issuer must thereafter be returned by Canadian LC Issuer, such Canadian Revolver
Lender shall return to Canadian LC Issuer the portion thereof which Canadian LC
Issuer has previously distributed to it.

     (e)  Calculations. A written advice setting forth in reasonable detail the
amounts owing under this section, submitted by Canadian LC Issuer to Canadian
Revolver Borrower or any Canadian Revolver Lender from time to time, shall be
conclusive, absent manifest error, as to the amounts thereof.

     Section 2B.15. Canadian Letter of Credit Fees. In consideration of Canadian
LC Issuer's issuance of any Canadian Letter of Credit, Canadian Revolver
Borrower agrees to pay (i) to Canadian Administration Agent for the account of
each Canadian Revolver Lender in proportion to its Percentage Share, a Canadian
Letter of Credit fee equal to the Canadian Letter of Credit Fee Rate applicable
each day times the face amount of such Canadian Letter of Credit and (ii) to
such Canadian LC Issuer for its own account, a letter of credit fronting fee at
a rate equal to one-eighth percent (.125%) per annum times the face amount of
such Canadian Letter of Credit. Each such fee will be calculated on the face
amount of each Canadian Letter of Credit outstanding on each day at the above
applicable rates and will be payable quarterly in arrears on the last day of
each March, June, September and December. In addition, Canadian Revolver
Borrower will pay to Canadian LC Issuer a minimum administrative issuance fee
and such other fees and charges customarily charged by the Canadian LC Issuer in
respect of any issuance, amendment or negotiation of any Canadian Letter of
Credit in accordance with the Canadian LC Issuer's published schedule of such
charges effective as of the date of such amendment or negotiation.

     Section 2B.16. No Duty to Inquire.

     (a)  Drafts and Demands. Canadian LC Issuer is authorized and instructed to
accept and pay drafts and demands for payment under any Canadian Letter of
Credit without requiring, and without responsibility for, any determination as
to the existence of any event giving rise to said draft, either at the time of
acceptance or payment or thereafter. Canadian LC Issuer is under no duty to
determine the proper identity of anyone presenting such a draft or making such a
demand (whether by tested telex or otherwise) as the officer, representative or
agent of any

                                       53

<PAGE>

beneficiary under any Canadian Letter of Credit, and payment by Canadian LC
Issuer to any such beneficiary when requested by any such purported officer,
representative or agent is hereby authorized and approved. Canadian Revolver
Borrower releases each Lender Party from, and agrees to hold each Lender Party
harmless and indemnified against, any liability or claim in connection with or
arising out of the subject matter of this section, WHICH INDEMNITY SHALL APPLY
WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY OR TO ANY EXTENT
CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY
LENDER PARTY, provided only that no Lender Party shall be entitled to
indemnification for that portion, if any, of any liability or claim which is
proximately caused by its own individual gross negligence or willful misconduct,
as determined in a final judgment.

     (b) Extension of Maturity. If the maturity of any Canadian Letter of Credit
is extended by its terms or by Law or governmental action, if any extension of
the maturity or time for presentation of drafts or any other modification of the
terms of any Canadian Letter of Credit is made at the request of any Restricted
Person, or if the amount of any Canadian Letter of Credit is increased at the
request of any Restricted Person, this Agreement shall be binding upon all
Restricted Persons with respect to such Canadian Letter of Credit as so
extended, increased or otherwise modified, with respect to drafts and property
covered thereby, and with respect to any action taken by Canadian LC Issuer,
Canadian LC Issuer's correspondents, or any Canadian Revolver Lender in
accordance with such extension, increase or other modification.

     (c) Transferees of Canadian Letters of Credit. If any Canadian Letter of
Credit provides that it is transferable, Canadian LC Issuer shall have no duty
to determine the proper identity of anyone appearing as transferee of such
Canadian Letter of Credit, nor shall Canadian LC Issuer be charged with
responsibility of any nature or character for the validity or correctness of any
transfer or successive transfers, and payment by Canadian LC Issuer to any
purported transferee or transferees as determined by Canadian LC Issuer is
hereby authorized and approved, and Canadian Revolver Borrower releases each
Lender Party from, and agrees to hold each Lender Party harmless and indemnified
against, any liability or claim in connection with or arising out of the
foregoing, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR
CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, provided only that no
Lender Party shall be entitled to indemnification for that portion, if any, of
any liability or claim which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment.

     Section 2B.17. Canadian LC Collateral.

     (a) Canadian LC Obligations in Excess of Canadian Revolver Commitment. If,
after the making of all mandatory prepayments required under Section 2B.4(c),
the outstanding Canadian LC Obligations will exceed the Canadian Revolver
Commitment, then in addition to prepayment of the entire principal balance of
the Canadian Revolver Loans, Canadian Revolver Borrower will immediately pay to
Canadian LC Issuer an amount equal to such excess. Canadian LC Issuer will hold
such amount as collateral security for the remaining Canadian LC Obligations
(all such amounts held as collateral security for Canadian LC Obligations being
herein collectively called "Canadian LC Collateral") and the other Obligations,
and such

                                       54

<PAGE>

collateral may be applied from time to time to any Matured Canadian LC
Obligations or other Obligations which are due and payable. Neither this
subsection nor the following subsection shall, however, limit or impair any
rights which Canadian LC Issuer may have under any other document or agreement
relating to any Canadian Letter of Credit, Canadian LC Collateral or Canadian LC
Obligation, including any LC Application, or any rights which any Canadian
Lender Party may have to otherwise apply any payments by Canadian Revolver
Borrower and any Canadian LC Collateral under Section 3B.1.

     (b) Acceleration of Canadian LC Obligations. If the Obligations or any part
thereof become immediately due and payable pursuant to Section 8.1 then, unless
all Canadian Revolver Lenders otherwise specifically elect to the contrary
(which election may thereafter be retracted by any Canadian Revolver Lender at
any time), all Canadian LC Obligations shall become immediately due and payable
without regard to whether or not actual drawings or payments on the Canadian
Letters of Credit have occurred, and Canadian Revolver Borrower shall be
obligated to pay to Canadian LC Issuer immediately an amount equal to the
aggregate Canadian LC Obligations which are then outstanding to be held as
Canadian LC Collateral.

     (c) Investment of Canadian LC Collateral. Pending application thereof, all
Canadian LC Collateral shall be invested by Canadian LC Issuer in such Cash
Equivalents as Canadian LC Issuer may choose in its sole discretion. All
interest on (and other proceeds of) such Investments shall be reinvested or
applied to Matured Canadian LC Obligations or other Obligations which are due
and payable. When all Obligations have been satisfied in full, including all
Canadian LC Obligations, all Canadian Letters of Credit have expired or been
terminated, and all of Canadian Borrowers's reimbursement obligations in
connection therewith have been satisfied in full, Canadian LC Issuer shall
release any remaining Canadian LC Collateral. Canadian Revolver Borrower hereby
assigns and grants to Canadian LC Issuer for the benefit of Canadian Revolver
Lenders a continuing security interest in all Canadian LC Collateral paid by it
to Canadian LC Issuer, all Investments purchased with such Canadian LC
Collateral, and all proceeds thereof to secure its Matured Canadian LC
Obligations and its Obligations under this Agreement, each Canadian Revolver
Note, and the other Loan Documents, and Canadian Revolver Borrower agrees that
such Canadian LC Collateral, Investments and proceeds shall be subject to all of
the terms and conditions of the Security Documents. Canadian Revolver Borrower
further agrees that Canadian LC Issuer shall have all of the rights and remedies
of a secured party under the Personal Property Security Act (Alberta) with
respect to such security interest and that an Event of Default under this
Agreement shall constitute a default for purposes of such security interest.

     (d) Payment of Canadian LC Collateral. When Canadian Revolver Borrower is
required to provide Canadian LC Collateral for any reason and fails to do so on
the day when required, Canadian LC Issuer or Canadian Administration Agent may
without prior notice to Canadian Revolver Borrower or any other Restricted
Person provide such Canadian LC Collateral (whether by application of proceeds
of other Collateral, by transfers from other accounts maintained with Canadian
LC Issuer, or otherwise) using any available funds of Canadian Revolver Borrower
or any other Person also liable to make such payments, and Canadian LC Issuer or
Canadian Administration Agent will give notice thereof to Canadian Revolver
Borrower promptly after such application or transfer. Any such amounts which are
required to be provided as Canadian LC Collateral and which are not provided on
the date

                                       55

<PAGE>

required shall, for purposes of each Security Document, be considered past due
Obligations owing hereunder, and Canadian LC Issuer is hereby authorized to
exercise its respective rights under each Security Document to obtain such
amounts.

     Section 2B.18. Hedging Contracts. All Hedging Contracts permitted hereunder
entered into with any one or more Canadian Revolver Lenders or their Affiliates
shall be deemed to be Obligations and be secured by all Collateral; subject,
however, to the provisions of the Intercreditor Agreement.

                            ARTICLE IIC - Term Loans

     Section 2C.1.  Term Loans. Subject to the terms and conditions hereof, each
Term Lender has made an advance to Term Borrower (herein called such Lender's
"Term Loan"), the outstanding amount of such Term Loan being as set forth on
Schedule 1 attached hereto. Portions of each Term Lender's Term Loan may from
time to time be designated as a Term Base Rate Loan or Term LIBOR Loan as
provided herein. The obligation of Term Borrower to repay to each Term Lender
the amount of the Term Loan made by such Term Lender to Term Borrower, together
with interest accruing in connection therewith, shall be evidenced by a single
promissory note (herein called such Term Lender's "Term Note") made by Term
Borrower payable to the order of such Term Lender in the form of Exhibit A-3
with appropriate insertions. The amount of principal owing on any Term Lender's
Term Note at any given time shall be the amount of such Term Lender's Term Loan
minus all payments of principal theretofore received by such Term Lender on such
Term Note. Interest on each Term Note shall accrue and be due and payable as
provided herein and therein. Each Term Note shall be due and payable as provided
herein and therein, and shall be due and payable in full on the Term Loan
Maturity Date. No portion of any Term Loan which has been repaid may be
reborrowed. Term Borrower may have no more than three Borrowings of Term LIBOR
Loans outstanding at any time. All payments of principal and interest on the
Term Loans shall be made in Dollars. All Term Loans shall be advanced to Term
Borrower in Dollars.

     Section 2C.2.  Continuations and Conversions of Existing Term Loans. Term
Borrower may make the following elections with respect to outstanding Term Loans
(1) to Convert, in whole or part, any Type of Term Loan to any other Type of
Term Loan, provided that any such Conversion of any Term LIBOR Loan must be made
on the last day of the Interest Period applicable thereto; and (2) to Continue,
in whole or in part, Term LIBOR Loans beyond the expiration of such Interest
Period by designating a new Interest Period to take effect at the time of such
expiration. In making such elections, Term Borrower may combine existing Term
Loans made pursuant to separate Borrowings into one new Borrowing or divide
existing Term Loans made pursuant to one Borrowing into separate new Borrowings,
provided that Term Borrower may have no more than three Borrowings of Term LIBOR
Loans outstanding at any time. To make any such election, Term Borrower must
give to Administrative Agent written notice (or telephonic notice promptly
confirmed in writing) of any such Conversion or Continuation of existing Term
Loans, with a separate notice given for each new Borrowing. Each such notice
constitutes a "Continuation/Conversion Notice" hereunder and must:

               (a)  specify the existing Term Loans which are to be Continued or
          Converted;

                                       56

<PAGE>

          (b)  specify (i) the aggregate amount of any Borrowing of Term Base
     Rate Loans into which such existing Term Loans are to be Continued or
     Converted and the date on which such Continuation or Conversion is to
     occur, or (ii) the aggregate amount of any Borrowing of Term LIBOR Loans
     into which such existing Term Loans are to be Continued or Converted, the
     date on which such Continuation or Conversion is to occur (which shall be
     the first day of the Interest Period which is to apply to such Term LIBOR
     Loans), and the length of the applicable Interest Period; and

          (c)  be received by Administrative Agent not later than 11:00 a.m.,
     Boston, Massachusetts time, on (i) the day on which any such Continuation
     or Conversion to Term Base Rate Loans is to occur, or (ii) the third
     Business Day preceding the day on which any such Continuation or Conversion
     to Term LIBOR Loans is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit B-3, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Term Borrower as to the matters which
are required to be set out in such written confirmation. Upon receipt of any
such Continuation/Conversion Notice, Administrative Agent shall give each Term
Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice
shall be irrevocable and binding on Term Borrower. During the continuance of any
Default, Term Borrower may not make any election to Convert existing Term Loans
into LIBOR Loans or Continue existing LIBOR Loans made under this Agreement as
LIBOR Loans beyond the last day of the respective and corresponding Interest
Period If (due to the existence of a Default or for any other reason) Term
Borrower fails to timely and properly give any Continuation/Conversion Notice
with respect to a Borrowing of existing LIBOR Loans at least three days prior to
the end of the Interest Period applicable thereto, such LIBOR Loans (to the
extent not prepaid at the end of such Interest Period) shall automatically be
Converted into Term Base Rate Loans at the end of such Interest Period. No new
funds shall be repaid by Term Borrower or advanced by any Term Lender in
connection with any Continuation or Conversion of existing Term Loans pursuant
to this section, and no such Continuation or Conversion shall be deemed to be a
new advance of funds for any purpose; such Continuations and Conversions merely
constitute a change in terms of already outstanding Term Loans and the interest
rate applicable thereto.

      Section 2C.3. Repayments.

     (a)  Scheduled Repayments of Principal. Subject to Section 2C.3(b) Term
Borrower shall repay the principal of the Term Loans as follows: (i) a principal
payment in the amount of $1,000,000 shall be due and payable on May 4, 2002,
which amount has been timely paid; (ii) a principal payment in the amount of
$7,000,000 shall be due and payable on May 4, 2003; (iii) a principal payment in
the amount of $8,000,000 shall be due and payable on each of May 4, 2004 and May
4, 2005; and (iv) the outstanding principal balance shall be due on the Term
Loan Maturity Date.

     (b)  Income Tax Act (Canada). Except as otherwise provided in Section 8.1,
notwithstanding anything to the contrary contained herein, in no event shall
Term Borrower be

                                       57

<PAGE>

required to repay 25% or more of the principal amount (as defined in the Income
Tax Act (Canada)) of the Term Loans made to it prior to five years and a day
after the date on which the Term Loans are made.

     (c) Interest Rates. Each Term Loan shall bear interest as follows: (i)
unless the Default Rate shall apply, (A) each Term Base Rate Loan shall bear
interest on each day outstanding at the US Base Rate plus the Term Base Rate
Margin in effect on such day, and (B) each Term LIBOR Loan shall bear interest
on each day during the related Interest Period at the related US LIBOR Rate plus
the Term LIBOR Rate Margin in effect on such day, and (ii) during a Default Rate
Period, all Term Loans shall bear interest on each day outstanding at the
applicable Default Rate. If an Event of Default based upon Section 8.1(a),
Section 8.1(b) or, with respect to Term Borrower, based upon Section 8.1(i)(i),
(i)(ii) or (i)(iii) exists and the Term Loans are not bearing interest at the
Default Rate, the past due principal and past due interest shall bear interest
on each day outstanding at the applicable Default Rate. The interest rate shall
change whenever the applicable US Base Rate, the US LIBOR Rate, Term Base Rate
Margin, or the Term LIBOR Rate Margin changes. In no event shall the interest
rate on any Term Loan exceed the Highest Lawful Rate.

     (d) Optional Prepayments. Term Borrower may, upon three Business Days'
notice, as to Term LIBOR Loans, or one Business Day's notice, as to Term Base
Rate Loans, to Administrative Agent (and Administrative Agent will promptly give
notice to the other Term Lenders) from time to time and without premium or
penalty prepay the Term Loans, in whole or in part, so long as the aggregate
amounts of all partial prepayments of principal on the Term Loans equals
$5,000,000 or any higher integral multiple of $1,000,000. Notwithstanding the
foregoing sentence, if Term Borrower shall prepay, in whole or in part, the Term
Loans before the first anniversary of the initial advance of the Term Loans,
voluntarily as provided in this subsection, Term Borrower shall pay to
Administrative Agent for the account of each Term Lender a prepayment premium
(the "Prepayment Premium") in an amount equal to one percent (1.0%) of the
amount of any such prepayment. Upon receipt of any notice described in the first
sentence of this subsection, Administrative Agent shall give each Term Lender
prompt notice of the terms thereof. Each prepayment of principal of a Term LIBOR
Loan under this subsection shall be accompanied by all interest then accrued and
unpaid on the principal so prepaid. Any principal or interest prepaid pursuant
to this subsection shall be in addition to, and not in lieu of, all payments
otherwise required to be paid under the Loan Documents at the time of such
prepayment.

     Section 2C.4. Use of Proceeds. In no event shall the funds from any Term
Loan be used directly or indirectly by any Person for personal, family,
household or agricultural purposes or for the purpose, whether immediate,
incidental or ultimate, of purchasing, acquiring or carrying any "margin stock"
(as such term is defined in Regulation U promulgated by the Board of Governors
of the Federal Reserve System) or to extend credit to others directly or
indirectly for the purpose of purchasing or carrying any such margin stock. Term
Borrower represents and warrants that it is not engaged principally, or as one
of its important activities, in the business of extending credit to others for
the purpose of purchasing or carrying such margin stock.

     Section 2C.5. Hedging Contracts. All Hedging Contracts permitted hereunder
entered into with any one or more Term Lenders or their Affiliates shall be
deemed to be Obligations and be secured by all Collateral; subject, however, to
the provisions of the Intercreditor Agreement.

                           ARTICLE IID - Term-B Loans

     Section 2D.1. Term-B Loans. Subject to the terms and conditions hereof,
each Term-B Lender has made an advance to US Borrower (herein called such
Lender's "Term-B Loan"), the outstanding amount of such Term-B Loan being set
forth on Schedule 1 attached hereto. Portions of each Term-B Lender's Term-B
Loan may from time to time be designated as a Term-B Base Rate Loan or Term-B
LIBOR Loan as provided herein. The obligation of US Borrower to repay to each
Term-B Lender the amount of the Term-B Loan made by such Term-B Lender to US
Borrower, together with interest accruing in connection therewith, shall be
evidenced by a single promissory note (herein called such Term-B Lender's
"Term-B Note") made by US Borrower payable to the order of such Term-B Lender in
the form of Exhibit A-4 with appropriate insertions. The amount of principal
owing on any Term-B Lender's Term-B Note at any given time shall be the amount
of such Term-B Lender's Term-B Loan minus all payments of principal theretofore
received by such Term-B Lender on such Term-B Note. Interest on each Term-B Note
shall accrue and be due and payable as provided herein and therein. Each Term-B
Note shall be due and payable as provided herein and therein, and shall be due
and payable in full on the Term-B Loan Maturity Date. No portion of any Term-B
Loan which has been repaid may be reborrowed. US Borrower may have no more than
three Borrowings of Term-B LIBOR Loans outstanding at any time. All payments of
principal and interest on the Term-B Loans shall be made in Dollars. All Term-B
Loans shall be advanced to US Borrower in Dollars.

     Section 2D.2. Continuations and Conversions of Existing Term-B Loans. US
Borrower may make the following elections with respect to outstanding Term-B
Loans (1) to Convert, in whole or part, any Type of Term-B Loan to any other
Type of Term-B Loan, provided that any such Conversion of any Term-B LIBOR Loan
must be made on the last day of the Interest Period applicable thereto; and (2)
to Continue, in whole or in part, Term-B LIBOR Loans beyond the expiration of
such Interest Period by designating a new Interest Period to take effect at the
time of such expiration. In making such elections, US Borrower may combine
existing Term-B Loans made pursuant to separate Borrowings into one new
Borrowing or divide existing Term-B Loans made pursuant to one Borrowing into
separate new Borrowings, provided that US Borrower may have no more than three
Borrowings of Term-B LIBOR Loans outstanding at any time. To make any such
election, US Borrower must give to Administrative Agent written notice (or
telephonic notice promptly confirmed in writing) of any such Conversion or
Continuation of existing Term-B Loans, with a separate notice given for each new
Borrowing. Each such notice constitutes a "Continuation/Conversion Notice"
hereunder and must:

               (a) specify the existing Term-B Loans which are to be Continued
          or Converted;

               (b) specify (i) the aggregate amount of any Borrowing of Term-B
          Base Rate Loans into which such existing Term-B Loans are to be
          Continued or Converted and the date on which such Continuation or
          Conversion is to occur, or (ii) the aggregate amount

                                       59

<PAGE>

          of any Borrowing of Term-B LIBOR Loans into which such existing Term-B
          Loans are to be Continued or Converted, the date on which such
          Continuation or Conversion is to occur (which shall be the first day
          of the Interest Period which is to apply to such Term-B LIBOR Loans),
          and the length of the applicable Interest Period; and

               (c)  be received by Administrative Agent not later than 11:00
          a.m., Boston, Massachusetts time, on (i) the day on which any such
          Continuation or Conversion to Term-B Base Rate Loans is to occur, or
          (ii) the third Business Day preceding the day on which any such
          Continuation or Conversion to Term-B LIBOR Loans is to occur. Each
          such written request or confirmation must be made in the form and
          substance of the "Continuation/Conversion Notice" attached hereto as
          Exhibit C-4, duly completed. Each such telephonic request shall be
          deemed a representation, warranty, acknowledgment and agreement by US
          Borrower as to the matters which are required to be set out in such
          written confirmation. Upon receipt of any such Continuation/Conversion
          Notice, Administrative Agent shall give each Term-B Lender prompt
          notice of the terms thereof. Each Continuation/Conversion Notice shall
          be irrevocable and binding on US Borrower. During the continuance of
          any Default, US Borrower may not make any election to Convert existing
          Term-B Loans into LIBOR Loans or Continue existing LIBOR Loans made
          under this Agreement as LIBOR Loans beyond the last day of the
          respective and corresponding Interest Period. If (due to the existence
          of a Default or for any other reason) US Borrower fails to timely and
          properly give any Continuation/Conversion Notice with respect to a
          Borrowing of existing LIBOR Loans at least three days prior to the end
          of the Interest Period applicable thereto, such LIBOR Loans (to the
          extent not prepaid at the end of such Interest Period) shall
          automatically be Converted into Term-B Base Rate Loans at the end of
          such Interest Period. No new funds shall be repaid by US Borrower or
          advanced by any Term-B Lender in connection with any Continuation or
          Conversion of existing Term-B Loans pursuant to this section, and no
          such Continuation or Conversion shall be deemed to be a new advance of
          funds for any purpose; such Continuations and Conversions merely
          constitute a change in terms of already outstanding Term-B Loans and
          the interest rate applicable thereto.

          Section 2D.3. Repayments.

          (a)  Scheduled Repayments of Principal. US Borrower shall repay the
principal of the Term-B Loans as follows: (i) a principal payment in an amount
equal to one percent of the original principal amount of the Term-B Loans shall
be due and payable on September 21 of each year, commencing September 21, 2002,
and (ii) the outstanding principal balance shall be due on the Term-B Loan
Maturity Date.

          (b)  Interest Rates. Each Term-B Loan shall bear interest as follows:
(i) unless the Default Rate shall apply, (A) each Term-B Base Rate Loan shall
bear interest on each day outstanding at the US Base Rate plus the Term-B Base
Rate Margin in effect on such day, and (B) each Term-B LIBOR Loan shall bear
interest on each day during the related Interest Period at the related US LIBOR
Rate plus the Term-B LIBOR Rate Margin in effect on such day, and (ii) during a
Default Rate Period, all Term-B Loans shall bear interest on each day
outstanding at the applicable Default Rate. If an Event of Default based upon
Section 8.1(a), Section 8.1(b) or,

                                       60

<PAGE>

with respect to US Borrower, based upon Section 8.1(i)(i), (i)(ii) or (i)(iii)
exists and the Term-B Loans are not bearing interest at the Default Rate, the
past due principal and past due interest shall bear interest on each day
outstanding at the applicable Default Rate. The interest rate shall change
whenever the applicable US Base Rate, the US LIBOR Rate, Term-B Base Rate
Margin, or the Term-B LIBOR Rate Margin changes. In no event shall the interest
rate on any Term-B Loan exceed the Highest Lawful Rate.

     (c)  Optional Prepayments. US Borrower may, upon three Business Days'
notice, as to Term-B LIBOR Loans, or one Business Day's notice, as to Term-B
Base Rate Loans, to Administrative Agent (and Administrative Agent will promptly
give notice to the other Term-B Lenders) from time to time and without premium
or penalty prepay the Term-B Loans, in whole or in part, so long as the
aggregate amounts of all partial prepayments of principal on the Term-B Loans
equals $5,000,000 or any higher integral multiple of $1,000,000. Each prepayment
of principal of a Term-B LIBOR Loan under this subsection shall be accompanied
by all interest then accrued and unpaid on the principal so prepaid. Any
principal or interest prepaid pursuant to this subsection shall be in addition
to, and not in lieu of, all payments otherwise required to be paid under the
Loan Documents at the time of such prepayment.

     Section 2D.4. Use of Proceeds. US Borrower shall use all Term-B Loans to
provide working capital for operations and for other general business purposes,
including acquisitions and refinancing Obligations, but not to pay distributions
to partners of Restricted Persons. In no event shall the funds from any Term-B
Loan be used directly or indirectly by any Person for personal, family,
household or agricultural purposes or for the purpose, whether immediate,
incidental or ultimate, of purchasing, acquiring or carrying any "margin stock"
(as such term is defined in Regulation U promulgated by the Board of Governors
of the Federal Reserve System) or to extend credit to others directly or
indirectly for the purpose of purchasing or carrying any such margin stock. US
Borrower represents and warrants that it is not engaged principally, or as one
of its important activities, in the business of extending credit to others for
the purpose of purchasing or carrying such margin stock.

                        ARTICLE III - Payments to Lenders

     Section 3.1.  General Procedures.

     (a)  Each Restricted Person shall pay all amounts owing such Restricted
Person with respect to any US Obligations (whether for principal, interest,
fees, or otherwise) to Administrative Agent for the account of the US Lender
Party to whom such payment is owed in Dollars, without set-off, deduction or
counterclaim, and in immediately available funds and each Restricted Person
shall pay all amounts owing by such Restricted Person with respect to any
Canadian Obligations (whether for principal, interest, fees, or otherwise) to
Canadian Administration Agent for the account of the Canadian Lender Party to
whom such payment is owed in Canadian Dollars (or with respect to Canadian
Revolver Loans funded in Dollars, in Dollars), without set-off, deduction or
counterclaim, and in immediately available funds; provided, however, that all
amounts paid by Administrative Agent on behalf of any Restricted Person in
accordance with Section 6.9 hereof shall be reimbursed to Administrative Agent
by US Borrower in the currency in which such amounts were paid by Administrative
Agent. If any

                                       61

<PAGE>

payment is received on account of any US Obligation in any currency other than
Dollars (whether voluntarily or pursuant to any order or judgment or the
enforcement thereof or the realization of any security or the liquidation of any
Person or otherwise howsoever), such payment shall constitute a discharge of the
liability of a Restricted Person hereunder and under the other Loan Documents in
respect of such US Obligation only to the extent of the amount of Dollars which
the relevant Lender Parties are able to purchase with the amount of the other
currency received by it on the Business Day next following such receipt by the
Administrative Agent in accordance with its normal procedures and after
deducting any premium and costs of exchange. If any payment is received on
account of any Canadian Obligation in any currency other than Canadian Dollars
(whether voluntarily or pursuant to any order or judgment or the enforcement
thereof or the realization of any security or the liquidation of any Person or
otherwise howsoever), such payment shall constitute a discharge of the liability
of a Restricted Person hereunder and under the other Loan Documents in respect
of such Canadian Obligation only to the extent of the amount of Canadian Dollars
which the relevant Lender Parties are able to purchase with the amount of the
other currency received by it on the Business Day next following such receipt by
Canadian Administration Agent in accordance with its normal procedures and after
deducting any premium and costs of exchange. Each payment under the Loan
Documents must be received by the relevant Agent not later than noon, Boston,
Massachusetts time or Toronto, Ontario time, as the case may be, on the date
such payment becomes due and payable. Any payment received by the relevant Agent
after such time will be deemed to have been made on the next following Business
Day. Should any such payment become due and payable on a day other than a
Business Day, the maturity of such payment shall be extended to the next
succeeding Business Day, and, in the case of a payment of principal or past due
interest, interest shall accrue and be payable thereon for the period of such
extension as provided in the Loan Document under which such payment is due. Each
payment under a Loan Document to a US Lender Party shall be due and payable at
the place provided therein and, if no specific place of payment is provided,
shall be due and payable at the place of payment of Administrative Agent's US
Note. Each Payment under a Loan Document to a Canadian Lender Party shall be due
and payable at the place provided therein, and, if no specific place of payment
is provided, shall be due and payable at the place of payment in Canadian
Administration Agent's Canadian Revolver Note.

     (b) When Administrative Agent collects or receives money on account of the
US Obligations, other than as provided in Section 3.9, Administrative Agent
shall distribute all money so collected or received, and each US Lender Party
shall apply all such money so distributed, as follows:

          (i)  first, for the payment of all US Obligations which are then due
     (and if such money is insufficient to pay all such US Obligations, first to
     any reimbursements due Administrative Agent under Section 6.9 or 10.4 and
     then to the partial payment of all other US Obligations then due in
     proportion to the amounts thereof, or as US Lender Parties shall otherwise
     agree);

          (ii) then for the prepayment of amounts owing under the Loan Documents
     (other than principal on the US Notes or the Term Notes) if so specified by
     US Borrower or Term Borrower;

                                       62

<PAGE>

          (iii) then for the prepayment of principal on the US Notes, together
     with accrued and unpaid interest on the principal so prepaid, and then held
     as US LC Collateral pursuant to Section 2A.13(c); and

          (iv)  last, for the payment or prepayment of any other US Obligations.

All payments applied to principal or interest on any US Note or Term Note shall
be applied first to any interest then due and payable, then to principal then
due and payable, and last to any prepayment of principal and accrued interest
thereon in compliance with Sections 2A.6, 2A.7 and 2C.3(d), as applicable. All
distributions of amounts described in any of subsections (ii), (iii), or (iv)
above shall be made by Administrative Agent pro rata to each US Lender Party
then owed US Obligations described in such subsection in proportion to all
amounts owed to all US Lender Parties which are described in such subsection;
provided that if any US Lender then owes payments to US LC Issuer for the
purchase of a participation under Section 2A.10 or to Administrative Agent under
Section 9.4, any amounts otherwise distributable under this section to such US
Lender shall be deemed to belong to US LC Issuer, or Administrative Agent,
respectively, to the extent of such unpaid payments, and Administrative Agent
shall apply such amounts to make such unpaid payments rather than distribute
such amounts to such US Lender.

     (c) When Canadian Administration Agent collects or receives money on
account of the Canadian Obligations, other than as provided in Section 3.9,
Canadian Administration Agent shall distribute all money so collected or
received, and each Canadian Lender Party shall apply all such money so
distributed, as follows:

          (i)   first, for the payment of all Canadian Obligations which are
     then due (and if such money is insufficient to pay all such Canadian
     Obligations, first to any reimbursements due Canadian Administration Agent
     under 10.4 and then to the partial payment of all other Canadian
     Obligations then due in proportion to the amounts thereof, or as Canadian
     Lender Parties shall otherwise agree);

          (ii)  then for the prepayment of amounts owing under the Loan
     Documents (other than principal on the Canadian Revolver Notes) if so
     specified by Canadian Revolver Borrower;

          (iii) then for the prepayment of principal on the Canadian Revolver
     Notes, together with accrued and unpaid interest on the principal so
     prepaid, and then held as Canadian LC Collateral pursuant to Section 2B.17;
     and

          (iv)  last, for the payment or prepayment of any other Canadian
     Obligations.

All payments applied to principal or interest on any Canadian Revolver Note
shall be applied first to any interest then due and payable, then to principal
then due and payable, and last to any prepayment of principal and accrued
interest thereon in compliance with Sections 2B.6 and 2B.7, as applicable. All
distributions of amounts described in any of subsections (ii), (iii), or (iv)
above shall be made by Canadian Administration Agent pro rata to each Canadian
Lender Party then owed Canadian Obligations described in such subsection in
proportion to all amounts owed

                                       63

<PAGE>

to all Canadian Lender Parties which are described in such subsection; provided
that if any Canadian Revolver Lender then owes payments to Canadian LC Issuer
for the purchase of a participation under Section 2B.14(c) or to Canadian
Administration Agent under Section 9.4, any amounts otherwise distributable
under this section to such Canadian Revolver Lender shall be deemed to belong to
Canadian LC Issuer, or Canadian Administration Agent, respectively, to the
extent of such unpaid payments, and Canadian Administration Agent shall apply
such amounts to make such unpaid payments rather than distribute such amounts to
such Canadian Revolver Lender.

     Section 3.2. Capital Reimbursement. If either (a) the introduction or
implementation of or the compliance with or any change in or in the
interpretation of any Law, or (b) the introduction or implementation of or the
compliance with any request, directive or guideline from any central bank or
other governmental authority (whether or not having the force of Law) affects or
would affect the amount of capital required or expected to be maintained by any
Lender Party or any corporation controlling any Lender Party, then, within five
Business Days after demand by such Lender Party, the relevant Borrower will pay
to the relevant Agent for the benefit of such Lender Party, from time to time as
specified by such Lender Party, such additional amount or amounts which such
Lender Party shall determine to be appropriate to compensate such Lender Party
or any corporation controlling such Lender Party in light of such circumstances,
to the extent that such Lender Party reasonably determines that the amount of
any such capital would be increased or the rate of return on any such capital
would be reduced by or in whole or in part based on the existence of the face
amount of such Lender Party's Loans, Letters of Credit, participations in
Letters of Credit, in Banker's Acceptances, or commitments under this Agreement.

     Section 3.3. Increased Cost of LIBOR Loans or Letters of Credit. If any
applicable Law (whether now in effect or hereinafter enacted or promulgated,
including Regulation D) or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration thereof
(whether or not having the force of Law):

          (a) shall change the basis of taxation of payments to any Lender Party
     of any principal, interest, or other amounts attributable to any LIBOR Loan
     or Letter of Credit or otherwise due under this Agreement in respect of any
     LIBOR Loan or Letter of Credit (other than taxes imposed on, or measured
     by, the overall net income of such Lender Party or any Applicable Lending
     Office of such Lender Party by any jurisdiction in which such Lender Party
     or any such Applicable Lending Office is located); or

          (b) shall change, impose, modify, apply or deem applicable any
     reserve, special deposit or similar requirements in respect of any LIBOR
     Loan or any Letter of Credit (excluding those for which such Lender Party
     is fully compensated pursuant to adjustments made in the definition of US
     LIBOR Rate) or against assets of, deposits with or for the account of, or
     credit extended by, such Lender Party; or

          (c) shall impose on any Lender Party or the interbank eurocurrency
     deposit market any other condition affecting any LIBOR Loan or Letter of
     Credit, the result of which is to increase the cost to any Lender Party of
     funding or maintaining any LIBOR

                                       64

<PAGE>

     Loan or of issuing any Letter of Credit or to reduce the amount of any sum
     receivable by any Lender Party in respect of any LIBOR Loan or Letter of
     Credit by an amount deemed by such Lender Party to be material,

then such Lender Party shall promptly notify Administrative Agent and Borrower
in writing of the happening of such event and of the amount required to
compensate such Lender Party for such event (on an after-tax basis, taking into
account any taxes on such compensation), whereupon (i) Borrower shall, within
five Business Days after demand therefor by such Lender Party, pay such amount
to Administrative Agent for the account of such Lender Party and (ii) Borrower
may elect, by giving to Administrative Agent and such Lender Party not less than
three Business Days' notice, to Convert all (but not less than all) of any such
LIBOR Loans into Base Rate Loans.

     Section 3.4. Notice; Change of Applicable Lending Office. A Lender Party
shall notify the relevant Borrower of any event occurring after the date of this
Agreement that will entitle such Lender Party to compensation under Section 3.2,
3.3, or 3.5 hereof as promptly as practicable, but in any event within 90 days,
after such Lender Party obtains actual knowledge thereof; provided, that (i) if
such Lender Party fails to give such notice within 90 days after it obtains
actual knowledge of such an event, such Lender Party shall, with respect to
compensation payable pursuant to Section 3.2, 3.3, or 3.5 in respect of any
costs resulting from such event, only be entitled to payment under Section 3.2,
3.3, or 3.5 hereof for costs incurred from and after the date 90 days prior to
the date that such Lender Party does give such notice and (ii) such Lender Party
will designate a different Applicable Lending Office for the Loans affected by
such event if such designation will avoid the need for, or reduce the amount of,
such compensation and will not, in the sole opinion of such Lender Party, be
disadvantageous to such Lender Party, except that such Lender Party shall have
no obligation to designate an Applicable Lending Office located in the United
States of America. Each Lender Party will furnish to the relevant Borrower a
certificate setting forth the basis and amount of each request by such Lender
Party for compensation under Section 3.2, 3.3, or 3.5 hereof.

     Section 3.5. Availability. If (a) any change in applicable Laws, or in the
interpretation or administration thereof of or in any jurisdiction whatsoever,
domestic or foreign, shall make it unlawful or impracticable for any Lender
Party to fund or maintain LIBOR Loans, accept BA's or to issue or participate in
Letters of Credit, or shall materially restrict the authority of any Lender
Party to purchase or take offshore deposits of dollars (i.e., "eurodollars"), or
(b) any Lender Party determines that matching deposits appropriate to fund or
maintain any LIBOR Loan are not available to it, or (c) any Lender Party
determines that the formula for calculating the US LIBOR Rate does not fairly
reflect the cost to such Lender Party of making or maintaining loans based on
such rate, in each case with respect to the relevant Commitment hereunder, then,
upon notice by such Lender Party to the relevant Borrower and the relevant
Agent, such Borrower's right to elect LIBOR Loans from such Lender Party or
issue BA's (or, if applicable, to obtain Letters of Credit) shall be suspended
to the extent and for the duration of such illegality, impracticability or
restriction and all LIBOR Loans of such Lender Party which are then outstanding
and all BA's which are then outstanding or are then the subject of any Borrowing
Notice and which cannot lawfully or practicably be maintained, funded or
accepted shall immediately become or remain, or shall be funded as, Base Rate
Loans of such Lender Party. With respect to each Commitment,

                                       65

<PAGE>

the relevant Borrower thereunder agrees to indemnify each Lender Party extending
credit pursuant thereto, and hold each such Lender Party harmless against all
costs, expenses, claims, penalties, liabilities and damages which may result
from any such change in Law, interpretation or administration. Such
indemnification shall be on an after-tax basis, taking into account any taxes
imposed on the amounts paid as indemnity.

         Section 3.6. Funding Losses. In addition to its other obligations
hereunder, with respect to each Commitment, the relevant Borrower thereunder
will indemnify each Lender Party extending credit pursuant thereto against, and
reimburse each Lender Party on demand for, any loss or expense incurred or
sustained by such Lender Party (including any loss or expense incurred by reason
of the liquidation or reemployment of deposits or other funds acquired by such
Lender Party to fund or maintain LIBOR Loans), as a result of (a) any payment or
prepayment (whether or not authorized or required hereunder) of all or a portion
of a LIBOR Loan on a day other than the day on which the applicable Interest
Period ends, (b) any payment or prepayment, whether or not required hereunder,
of a Loan made after the delivery, but before the effective date, of a
Continuation/Conversion Notice, if such payment or prepayment prevents such
Continuation/Conversion Notice from becoming fully effective, (c) the failure of
any Loan to be made or of any Continuation/Conversion Notice to become effective
due to any condition precedent not being satisfied or due to any other action or
inaction of any Restricted Person, or (d) any Conversion (whether or not
authorized or required hereunder) of all or any portion of any LIBOR Loan into a
Base Rate Loan or into a different LIBOR Loan on a day other than the day on
which the applicable Interest Period ends. Such indemnification shall be on an
after-tax basis, taking into account any taxes imposed on the amounts paid as
indemnity.

         Section 3.7. Reimbursable Taxes. With respect to each Commitment, the
relevant Borrower thereunder covenants and agrees with each Lender Party
extending credit pursuant thereto that:

                  (a) Such Borrower will indemnify each such Lender Party
         against and reimburse each such Lender Party for all present and future
         stamp and other taxes, duties, levies, imposts, deductions, charges,
         costs, and withholdings whatsoever imposed, assessed, levied or
         collected on or in respect of this Agreement, any LIBOR Loans, any BA's
         or Letters of Credit (whether or not legally or correctly imposed,
         assessed, levied or collected) including all taxes imposed pursuant to
         Part XIII of the Income Tax Act (Canada) and any withholding or other
         taxes imposed on any Lender Party under Canadian Law, excluding,
         however, any taxes imposed on or measured by the overall net income of
         any Agent or such Lender Party or any Applicable Lending Office of such
         Lender Party by any jurisdiction in which such Lender Party or any such
         Applicable Lending Office is located (all such non-excluded taxes,
         levies, costs and charges being collectively called "Reimbursable
         Taxes" in this section). Such indemnification shall be on an after-tax
         basis, taking into account any taxes imposed on the amounts paid as
         indemnity.

                  (b) All payments on account of the principal of, and interest
         on, each such Lender Party's Loans and Notes, and all other amounts
         payable by such Borrower to any such Lender Party hereunder, shall be
         made in full without set-off or counterclaim and

                                       66

<PAGE>

     shall be made free and clear of and without deductions or withholdings of
     any nature by reason of any Reimbursable Taxes, all of which will be for
     the account of the relevant Borrower. In the event of any such Borrower
     being compelled by Law to make any such deduction or withholding from any
     payment to any such Lender Party, such Borrower shall pay on the due date
     of such payment, by way of additional interest, such additional amounts as
     are needed to cause the amount receivable by such Lender Party after such
     deduction or withholding to equal the amount which would have been
     receivable in the absence of such deduction or withholding. If any such
     Borrower should make any deduction or withholding as aforesaid, such
     Borrower shall within 60 days thereafter forward to such Lender Party an
     official receipt or other official document evidencing payment of such
     deduction or withholding.

          (c) If any such Borrower is ever required to pay any Reimbursable Tax
     with respect to any LIBOR Loan, such Borrower may elect, by giving to the
     relevant Agent and such Lender Party not less than three Business Days'
     notice, to Convert all (but not less than all) of any such LIBOR Loan into
     a Base Rate Loan, but such election shall not diminish such Borrower's
     obligation to pay all Reimbursable Taxes.

          (d) Notwithstanding the foregoing provisions of this section, such
     Borrower shall be entitled, to the extent it is required to do so by Law,
     to deduct or withhold (and not to make any indemnification or reimbursement
     for) income or other similar taxes imposed by the United States of America
     or Canada (other than any portion thereof attributable to a change in
     federal income tax Laws effected after the date hereof) from interest, fees
     or other amounts payable hereunder for the account of such Lender Party,
     other than such a Lender Party (i) who is a US person for Federal income
     tax purposes or (ii) who has the Prescribed Forms on file with
     Administrative Agent (with copies provided to the relevant Borrower) for
     the applicable year to the extent deduction or withholding of such taxes is
     not required as a result of the filing of such Prescribed Forms, provided
     that if such Borrower shall so deduct or withhold any such taxes, it shall
     provide a statement to Administrative Agent and such Lender Party, setting
     forth the amount of such taxes so deducted or withheld, the applicable rate
     and any other information or documentation which such Lender Party may
     reasonably request for assisting such Lender Party to obtain any allowable
     credits or deductions for the taxes so deducted or withheld in the
     jurisdiction or jurisdictions in which such Lender Party is subject to tax.
     As used in this section, "Prescribed Forms" means such duly executed forms
     or statements, and in such number of copies, which may, from time to time,
     be prescribed by Law and which, pursuant to applicable provisions of (x) an
     income tax treaty between the United States and the country of residence of
     such Lender Party providing the forms or statements, (y) the Code, or (z)
     any applicable rules or regulations thereunder, permit such Borrower to
     make payments hereunder for the account of such Lender Party free of such
     deduction or withholding of income or similar taxes.

     Section 3.8. Replacement of Lenders. If any Lender Party seeks
reimbursement for increased costs under Sections 3.2 through 3.7, then within
ninety days thereafter -- provided no Event of Default then exists -- each
Borrower shall have the right (unless such Lender Party withdraws its request
for additional compensation) to replace such Lender Party by requiring

                                       67

<PAGE>

such Lender Party to assign its Loans and Notes and its commitments hereunder to
an Eligible Transferee reasonably acceptable to Administrative Agent and to the
relevant Borrower, provided that: (i) all Obligations of such Borrower owing to
such Lender Party being replaced (including such increased costs and any
breakage costs with respect to any outstanding LIBOR Loans, but excluding
principal and accrued interest on the Notes being assigned) shall be paid in
full to such Lender Party concurrently with such assignment, and (ii) the
replacement Eligible Transferee shall purchase the Notes being assigned by
paying to such Lender Party a price equal to the principal amount thereof plus
accrued and unpaid interest and accrued and unpaid commitment fees thereon. In
connection with any such assignment the relevant Borrower, Administrative Agent,
such Lender Party and the replacement Eligible Transferee shall otherwise comply
with Section 10.5. Notwithstanding the foregoing rights of each Borrower under
this section, however, Borrowers may not replace any Lender Party which seeks
reimbursement for increased costs under Section 3.2 through 3.7 unless such
Borrower is at the same time replacing all Lender Parties which are then seeking
such compensation.

         Section 3.9. Application of Proceeds After Acceleration. If any Event
of Default shall have occurred and be continuing, and if the Obligations have
become due and payable, all cash collateral held by Administrative Agent or
Canadian Administration Agent under this Agreement and the proceeds of any sale,
disposition, or other realization by Administrative Agent, Canadian
Administration Agent or the collateral agent under the Intercreditor Agreement
upon the Collateral (or any portion thereof) pursuant to the Security Documents,
shall be distributed in whole or in part by Administrative Agent in the
following order of priority, unless otherwise directed by all of the Lenders:

         First, to the Administrative Agent and Canadian Administration Agent,
ratably, in an amount equal to all reimbursements to Administrative Agent or
Canadian Administration Agent due and payable as of the date of such
distribution; provided, however, that in case such proceeds shall be
insufficient to pay in full all such Obligations, then to the payment thereof to
the Administrative Agent and Canadian Administration Agent, ratably, in
proportion to its percentage of the sum of the aggregate amounts of all such
Obligations;

         Second, to the Lenders, ratably, in an amount equal to all accrued and
unpaid interest and fees owing to the Lenders under this Agreement due and
payable as of the date of such distribution; provided, however, that in case
such proceeds shall be insufficient to pay in full all such Obligations, then to
the payment thereof to the Lenders, ratably, in proportion to its percentage of
the sum of the aggregate amounts of all such Obligations;

         Third, to the Lenders, ratably, in an amount equal to all Loans plus LC
Obligations; provided, however, that in the case such proceeds shall be
insufficient to pay in full all such Obligations, then to the payment thereof to
the Lenders, ratably, in proportion to its percentage of the sum of the
aggregate amounts of all such Obligations;

         Fourth, to the Lenders, ratably, in an amount equal to all amounts
owing to the Lenders under all Obligations with respect to Hedging Contracts
between any Restricted Person and any Lender or an Affiliate; provided, however,
that in case such proceeds shall be insufficient to pay

                                       68

<PAGE>

in full all such Obligations, then to the payment thereof to the Lenders,
ratably, in proportion to its percentage of the sum of the aggregate amounts of
all such Obligations;

     Fifth, to the Lenders in an amount equal to all other Obligations;
provided, however, that in the case such proceeds shall be insufficient to pay
in full such Obligations, then to the payment thereof to the Lenders, ratably,
in proportion to its percentage of the sum of the aggregate amounts of all such
Obligations; and

     Sixth, to the extent of any surplus, to the Restricted Persons as their
respective interests may appear, except as may be provided otherwise by law;
it being understood that the Restricted Persons shall remain liable to the
extent of any deficiency between the amount of proceeds of the Collateral and
the aggregate sums referred to in clauses First through Fifth above.

     Section 3.10. Currency Conversion and Indemnity.

     (a) If, for the purpose of obtaining or enforcing judgment in any court in
any jurisdiction, it becomes necessary to convert into a particular currency
(the "Judgment Currency") any amount due under a Loan Document in the currency
in which it was effected (the "Agreed Currency") then the conversion shall be
made on the basis of the rate of exchange prevailing on the Business Day
preceding the date such judgment is given and in any event each Restricted
Person obligated to pay such Obligation shall be obligated to pay the relevant
Lender Parties any deficiency in accordance with Section 3.10(b). For the
foregoing purposes "rate of exchange" means the rate at which the relevant
Agent, as applicable, in accordance with its normal banking procedures is able
on the relevant date to purchase the Agreed Currency with the Judgment Currency
after deducting any premium and costs of exchange.

     (b) If any Lender Party receives any payment or payments on account of the
liability of a Restricted Person under the Loan Documents pursuant to any
judgment or order in any currency other than the Agreed Currency (an "Other
Currency"), and the amount of the Agreed Currency which the relevant Lender
Party is able to purchase on the Business Day next following such receipt with
the proceeds of such payment or payments in accordance with its normal
procedures and after deducting any premiums and costs of exchange is less than
the amount of the Agreed Currency due in respect of such Obligations immediately
prior to such judgment or order, then the Borrower owing such Obligation on
demand shall, and such Borrower hereby agrees to, indemnify and save such Lender
Party harmless from and against any loss, cost or expense arising out of or in
connection with such deficiency. The agreement of indemnity provided for in this
Section 3.10(b) shall constitute an obligation separate and independent from all
other obligations contained in this Agreement, shall give rise to a separate and
independent cause of action, shall apply irrespective of any indulgence granted
by the Lender Parties or any of them from time to time, and shall continue in
full force and effect notwithstanding any judgment or order for a liquidated sum
in respect of an amount due hereunder or under any judgment or order.

                   ARTICLE V - Representations and Warranties

         To confirm each Lender's understanding concerning Restricted Persons
and Restricted Persons' businesses, properties and obligations and to induce
each Lender to enter into this

                                       74

<PAGE>

Agreement and to extend credit hereunder, Plains MLP, US Borrower, Term
Borrower, and Canadian Revolver Borrower represent and warrant to each Lender
that:

         Section 5.1.   No Default. No Restricted Person is in default in the
performance of any of the covenants and agreements contained in any Loan
Document. No event has occurred and is continuing which constitutes a Default.

         Section 5.2.   Organization and Good Standing. Each Restricted Person
is duly organized, validly existing and in good standing under the Laws of its
jurisdiction of organization, having all powers required to carry on its
business and enter into and carry out the transactions contemplated hereby. Each
Restricted Person is duly qualified, in good standing, and authorized to do
business in all other jurisdictions within the United States and Canada wherein
the character of the properties owned or held by it or the nature of the
business transacted by it makes such qualification necessary except where the
failure to so qualify would not cause a Material Adverse Change. Each Restricted
Person has taken all actions and procedures customarily taken in order to enter,
for the purpose of conducting business or owning property, each jurisdiction
outside the United States and Canada wherein the character of the properties
owned or held by it or the nature of the business transacted by it makes such
actions and procedures necessary except where the failure to so qualify would
not cause a Material Adverse Change.

         Section 5.3.   Authorization. Each Restricted Person has duly taken all
action necessary to authorize the execution and delivery by it of the Loan
Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder. Each of US Borrower, Term Borrower, and Canadian Revolver Borrower
is duly authorized to borrow funds hereunder.

         Section 5.4.   No Conflicts or Consents. The execution and delivery by
the various Restricted Persons of the Loan Documents to which each is a party,
the performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (i) conflict with any provision of (1) any Law, (2) the
organizational documents of any Restricted Person or any of its Affiliates, or
(3) any agreement, judgment, license, order or permit applicable to or binding
upon any Restricted Person or any of its Affiliates, (ii) result in the
acceleration of any Indebtedness owed by any Restricted Person or any of its
Affiliates, or (iii) result in or require the creation of any Lien upon any
assets or properties of any Restricted Person or any of its Affiliates except as
expressly contemplated in the Loan Documents. Except as expressly contemplated
in the Loan Documents or disclosed in the Disclosure Schedule, no permit,
consent, approval, authorization or order of, and no notice to or filing,
registration or qualification with, any Tribunal or third party is required (i)
in connection with the execution, delivery or performance by any Restricted
Person of any Loan Document, or (ii) to consummate any transactions contemplated
by the Loan Documents.

         Section 5.5.   Enforceable Obligations. This Agreement is, and the
other Loan Documents when duly executed and delivered will be, legal, valid and
binding obligations of each Restricted Person which is a party hereto or
thereto, enforceable in accordance with their terms except as

                                       75

<PAGE>

such enforcement may be limited by bankruptcy, insolvency or similar Laws of
general application relating to the enforcement of creditors' rights.

     Section 5.6. Initial Financial Statements. Plains MLP has heretofore
delivered to each Lender true, correct and complete copies of the Initial
Financial Statements. The Initial Financial Statements other than pro forma
financial statements fairly present Plains MLP's Consolidated and consolidating
financial position at the date thereof and the Consolidated and consolidating
results of Plains MLP's operations for the periods thereof, and in the case of
the annual Initial Financial Statements, Consolidated cash flows for the period
thereof. The pro forma Initial Financial Statements fairly present Plains MLP's
pro forma Consolidated and consolidating financial position at the date thereof
and the pro forma Consolidated results of Plains MLP's operations for the period
thereof. Since the date of the annual Initial Financial Statements no Material
Adverse Change has occurred, except as reflected in the quarterly Initial
Financial Statements or in the Disclosure Schedule. All Initial Financial
Statements other than pro forma financial statements were prepared in accordance
with GAAP. All Initial Financial Statements that are pro forma financial
statements were prepared in accordance with GAAP with such pro forma adjustments
as have been accepted by Administrative Agent.

     Section 5.7. Other Obligations and Restrictions. No Restricted Person has
any outstanding Liabilities of any kind (including contingent obligations, tax
assessments, and unusual forward or long-term commitments) which are, in the
aggregate, material to Plains MLP or material with respect to Plains MLP's
Consolidated financial condition and not shown in the Initial Financial
Statements, disclosed in the Disclosure Schedule or otherwise permitted under
Section 7.1. Except as shown in the Initial Financial Statements or disclosed in
the Disclosure Schedule, no Restricted Person is subject to or restricted by any
franchise, contract, deed, charter restriction, or other instrument or
restriction which could cause a Material Adverse Change.

     Section 5.8. Full Disclosure. No certificate, statement or other
information delivered herewith or heretofore by any Restricted Person to any
Lender in connection with the negotiation of this Agreement or in connection
with any transaction contemplated hereby contains any untrue statement of a
material fact or omits to state any material fact necessary to make the
statements contained herein or therein, in light of the circumstances under
which they were made, not misleading as of the date made or deemed made. All
written information furnished after the date hereof by or on behalf of any
Restricted Person to Administrative Agent or any Lender Party in connection with
this Agreement and the other Loan Documents and the transactions contemplated
hereby and thereby will be true, complete and accurate in every material respect
in light of the circumstances in which made or based on reasonable estimates on
the date as of which such information is stated or certified. There is no fact
known to any Restricted Person that has not been disclosed to each Lender in
writing which could cause a Material Adverse Change.

     Section 5.9. Litigation. Except as disclosed in the Initial Financial
Statements, in the Disclosure Schedule or pursuant to Section 6.4: (i) there are
no actions, suits or legal, equitable, arbitrative or administrative proceedings
pending, or to the knowledge of any Restricted Person threatened, against any
Restricted Person or affecting any Collateral (including, without limitation,
any which challenge or otherwise pertain to any Restricted Person's title to any

                                       76

<PAGE>

Collateral) before any Tribunal which could reasonably be expected to cause a
Material Adverse Change, and (ii) there are no outstanding judgments,
injunctions, writs, rulings or orders by any such Tribunal against any
Restricted Person or any Restricted Person's stockholders, partners, directors
or officers or affecting any Collateral which could reasonably be expected to
cause a Material Adverse Change.

     Section 5.10. Labor Disputes and Acts of God. Except as disclosed in the
Disclosure Schedule or otherwise disclosed in writing to Administrative Agent,
neither the business nor the properties of any Restricted Person has been
affected by any fire, explosion, accident, strike, lockout or other labor
dispute, drought, storm, hail, earthquake, embargo, act of God or of the public
enemy or other casualty (whether or not covered by insurance), which could cause
a Material Adverse Change.

     Section 5.11. ERISA Plans and Liabilities. All currently existing ERISA
Plans are listed in the Disclosure Schedule. Except as disclosed in the Initial
Financial Statements or in the Disclosure Schedule, no Termination Event has
occurred with respect to any ERISA Plan and all ERISA Affiliates are in
compliance with ERISA in all material respects. No ERISA Affiliate is required
to contribute to, or has any other absolute or contingent liability in respect
of, any "multiemployer plan" as defined in Section 4001 of ERISA. Except as set
forth in the Disclosure Schedule: (i) no "accumulated funding deficiency" (as
defined in Section 412(a) of the Code) exists with respect to any ERISA Plan,
whether or not waived by the Secretary of the Treasury or his delegate, and (ii)
the current value of each ERISA Plan's benefits does not exceed the current
value of such ERISA Plan's assets available for the payment of such benefits by
more than $500,000.

     Section 5.12. Compliance with Laws. Except as set forth in the Disclosure
Schedule, each Restricted Person has all permits, licenses and authorizations
required in connection with the conduct of its businesses, except to the extent
failure to have any such permit, license or authorization could not cause a
Material Adverse Change. Each Restricted Person is in compliance with the terms
and conditions of all such permits, licenses and authorizations, and is also in
compliance with all other limitations, restrictions, conditions, standards,
prohibitions, requirements, obligations, schedules and timetables contained in
any Law, including applicable Environmental Law, or in any regulation, code,
plan, order, decree, judgment, injunction, notice or demand letter issued,
entered, promulgated or approved thereunder, except to the extent failure to
comply could not cause a Material Adverse Change. Without limiting the
foregoing, each Restricted Person (i) has filed and maintained all tariffs
applicable to its business with each applicable commission, (ii) and all such
tariffs are in compliance with all Laws administered or promulgated by each
applicable commission and (iii) has imposed charges on its customers in

1980, as amended,

                                       77

<PAGE>

"CERCLIS" means the Comprehensive Environmental Response, Compensation and
Liability Information System List of the Environmental Protection Agency, and
"Release" has the meaning given such term in 42 U.S.C. (S) 9601(22). Without
limiting the provisions of Section 5.12, and except as set forth in the

         or with respect to any such generation, treatment, storage, recycling,
         transportation, disposal, or Release.

                  (b)  No Restricted Person otherwise has any known material
         contingent liability in connection with any alleged generation,
         treatment, storage, recycling, transportation, disposal, or Release of
         any Hazardous Materials.

                  (c)  No Restricted Person has handled any Hazardous Materials,
         other than as a generator, on any properties now or previously owned or
         leased by any Restricted Person to an extent that such handling has
         caused, or could cause, a Material Adverse Change.

                       (iv)  no Hazardous Materials have been Released at, on or
                  under any properties now or previously owned or leased by any

                                       78

<PAGE>

not caused and could not cause a Material Adverse Change, any location listed on
any similar state list or which is the subject of federal, state or local

resources or for personal injury claims, including, but not limited to, claims
under CERCLA.

         (f) No property now or previously owned or leased by any Restricted

list of sites requiring investigation or clean-up.

         (g) There are no Liens arising under or pursuant to any Environmental
Laws on any of the real properties or properties owned or leased by any

owned by it in any deed to such properties.

         (h) There have been no environmental investigations, studies, audits,

unless failure to so comply could not reasonably be expected to cause a Material
Adverse Change; (ii) none of the operations or properties of Canadian Revolver
Borrower, Term Borrower or any Subsidiary of either such Person is the subject
of federal, provincial or local investigation evaluating whether any material
remedial action is needed to respond to a release of any Hazardous Materials
into the environment or to the improper storage or disposal (including storage
or disposal at offsite locations) of any Hazardous Materials, unless such
remedial action could not reasonably be expected to cause a Material Adverse
Change; and (iii) neither Canadian Revolver Borrower nor Term Borrower nor any
Subsidiary of either such Person (and to the best knowledge of Canadian Revolver
Borrower and Term Borrower, no other Person) has filed any notice under any Law
indicating that any such Person is responsible for the improper release into the
environment, or the improper storage or disposal, of any material amount of any
Hazardous Materials or that any Hazardous Materials have been improperly
released, or are improperly stored or disposed of, upon any property of any such
Person, unless such failure to so comply could not reasonably be expected to
cause a Material Adverse Change.

association of any type whatsoever except those listed in the Disclosure

of electricity, gas, steam, water or other public utility services. Neither US
Borrower, Term Borrower, Canadian Revolver Borrower, nor any other Restricted

Guarantor and the consummation of the transactions contemplated hereby, (i) US
Borrower, Term Borrower, Canadian Revolver Borrower, and each Guarantor will be
solvent (as such term is used in applicable bankruptcy, liquidation,

Borrower's, Term Borrower's, Canadian Revolver Borrower's, and each Guarantor's
capital should be adequate for the businesses in which such Restricted Person is

believe that it will incur, debts which will be beyond its ability to pay as
such debts mature.

Restricted Person will notify each Lender Party, not later than five (5)
Business Days after any executive officer of Restricted Persons has knowledge
thereof, stating that such notice is being given pursuant to this Agreement, of:

                (a) the occurrence of any Material Adverse Change,

                (b) the occurrence of any Default,

                (c) the acceleration of the maturity of any Indebtedness owed
         by any Restricted Person or of any default by any Restricted Person
         under any indenture, mortgage, agreement, contract or other instrument
         to which any of them is a party or by

                                       84

<PAGE>

         which any of them is a party or by which any of them or any of their
         properties is bound, if such acceleration or default could cause a
         Material Adverse Change,

                 (d)  the occurrence of any Termination Event,

                 (e)  Under any Environmental Law, any claim of the Dollar
         Equivalent of $1,000,000 or more, any notice of potential liability
         which might be reasonably likely to exceed such amount, or any other
         material adverse claim asserted against any Restricted Person or with
         respect to any Restricted Person's properties taken as a whole, and

                 (f)  the filing of any suit or proceeding, or the assertion in
         writing of a claim against any Restricted Person or with respect to any
         Restricted Person's properties in which an adverse decision reasonably
         could be expected to cause a Material Adverse Change.

Upon the occurrence of any of the foregoing Restricted Persons will take all
necessary or appropriate steps to remedy promptly any such Material Adverse
Change, Default, acceleration, default or Termination Event, to protect against
any such adverse claim, to defend any such suit or proceeding, and to resolve
all controversies on account of any of the foregoing. Restricted Persons will
also notify Administrative Agent and Administrative Agent's counsel in writing
at least twenty Business Days prior to the date that any Restricted Person
changes its name or the location of its chief executive office or principal
place of business or the place where it keeps its books and records concerning
the Collateral, furnishing with such notice any necessary financing statement
amendments or requesting Administrative Agent and its counsel to prepare the
same.

         Section 6.5. Maintenance of Properties. Each Restricted Person will
maintain, preserve, protect, and keep all Collateral and all other property used
or useful in the conduct of its business in good condition (ordinary wear and
tear excepted) and in compliance with all applicable Laws, and will from time to
time make all repairs, renewals and replacements needed to enable the business
and operations carried on in connection therewith to be promptly and
advantageously conducted at all times.

         Section 6.6. Maintenance of Existence and Qualifications. Each
Restricted Person will maintain and preserve its existence and its rights and
franchises in full force and effect and will qualify to do business in all
states or jurisdictions where required by applicable Law, except where the
failure so to qualify will not cause a Material Adverse Change.

         Section 6.7. Payment of Trade Liabilities, Taxes, etc. Each Restricted
Person will (a) timely file all required tax returns (including any extensions);
(b) timely pay all taxes, assessments, and other governmental charges or levies

ordinary course of its business; (d) pay and discharge when due all other
Liabilities now or hereafter owed by it, other than royalty payments suspended

reserves for all of the foregoing in accordance with GAAP. Each

                                       85

<PAGE>

Restricted Person may, however, delay paying or discharging any of the foregoing
so long as it is in good faith contesting the validity thereof by appropriate
proceedings, if necessary, and has set aside on its books adequate reserves
therefor which are required by GAAP.

     Section 6.8.  Insurance. Each Restricted Person shall at all times maintain
insurance for its property in accordance with the Insurance Schedule, which
insurance shall be by financially sound and reputable insurers. Each Restricted
Person will maintain any additional insurance coverage as described in the
respective Security Documents. Upon demand by Administrative Agent any insurance
policies covering Collateral shall be endorsed (a) to provide for payment of
losses to Administrative Agent as its interests may appear, (b) to provide that
such policies may not be canceled or reduced or affected in any material manner
for any reason without fifteen days prior notice to Administrative Agent, and
(c) to provide for any other matters specified in any applicable Security
Document or which Administrative Agent may reasonably require. Each Restricted
Person shall at all times maintain insurance against its liability for injury to
persons or property in accordance with the Insurance Schedule, which insurance
shall be by financially sound and reputable insurers. Without limiting the
foregoing, each Restricted Person shall at all time maintain liability insurance
in accordance with the Insurance Schedule.

     Section 6.9.  Performance on Borrower's Behalf. If any Restricted Person
fails to pay any taxes, insurance premiums, expenses, attorneys' fees or other
amounts it is required to pay under any Loan Document, Administrative Agent may
pay the same after notice of such payment by Administrative Agent is given to US
Borrower. US Borrower shall immediately reimburse Administrative Agent for any
such payments and each amount paid by Administrative Agent shall constitute an
Obligation owed hereunder which is due and payable on the date such amount is
paid by Administrative Agent.

     Section 6.10. Interest. Each of US Borrower, Term Borrower, and Canadian
Revolver Borrower hereby promises to each Lender to pay interest at the Default
Rate on all Obligations (including Obligations to pay fees or to reimburse or
indemnify any Lender) which such Person has in this Agreement promised to pay to
such Lender and which are not paid when due. Such interest shall accrue from the
date such Obligations become due until they are paid.

     Section 6.11. Compliance with Agreements and Law. Each Restricted Person
will perform all material obligations it is required to perform under the terms
of each indenture, mortgage, deed of trust, security agreement, lease, and
franchise, and each material agreement, contract or other instrument or
obligation to which it is a party or by which it or any of its properties is
bound. Each Restricted Person will conduct its business and affairs in
compliance with all Laws applicable thereto.

     all environmental, health and safety permits, licenses

                                       86

         such authorizations in full force and effect.

                   (b)   Each Restricted Person will promptly furnish to
         Administrative Agent all written notices of violation, orders, claims,
         citations, complaints, penalty assessments, suits or other proceedings
         received by any Restricted Person or General Partner, or of which it
         has notice, pending or threatened against any Restricted Person, the
         potential liability of which exceeds the Dollar Equivalent of
         $1,000,000 or would cause a Material Adverse Change if resolved
         adversely against any Restricted Person, by any governmental authority
         with respect to any alleged violation of or non-compliance with any
         Environmental Laws or any permits, licenses or authorizations in
         connection with its ownership or use of its properties or the operation
         of its business.

                   (c)   Each Restricted Person will promptly furnish to
         Administrative Agent all requests for information, notices of claim,
         demand letters, and other notifications, received by any Restricted

         its properties or the conduct of its business, relating to potential
         responsibility with respect to any investigation or clean-up of
         Hazardous Material at any location, the potential liability of which
         exceeds the Dollar Equivalent of $1,000,000 or would cause a Material
         Adverse Change if resolved adversely against any Restricted Person.

         Section 6.13.   Evidence of Compliance. Subject to the last sentence of
Section 6.3, each Restricted Person will furnish to each Lender at such
Restricted Person's expense all evidence which Administrative Agent from time to
time reasonably requests in writing as to the accuracy and validity of or
compliance with all representations, warranties and covenants made by any
Restricted Person in the Loan Documents, the satisfaction of all conditions
contained therein, and all other matters pertaining thereto.

         Section 6.14.   Agreement to Deliver Security Documents. Restricted
Persons will deliver, and will cause each Person, other than Unrestricted
Subsidiaries, in which it owns any capital stock or other equity interest (other
than interests described in clause (d) of the definition of "Permitted
Investments"), to deliver, to further secure the Obligations whenever requested
by Administrative Agent in its sole and absolute discretion, deeds of trust,
mortgages, chattel mortgages, security agreements, financing statements and
other Security Documents in form and substance satisfactory to Administrative
Agent for the purpose of granting, confirming, and perfecting first and prior
liens or security interests in any real or personal property now owned or
hereafter acquired by any Restricted Person; provided, with respect to any such
property for which the consent or approval of third parties is required for the
delivery of such Security Documents, Restricted Persons shall not be required to
deliver, or to cause such Person to deliver, such Security Documents with
respect to such property, but shall use their commercially reasonable best
efforts, as determined by Administrative Agent, to deliver, or to cause such
Person to deliver, such Security Documents with respect to such property.
Without limiting the foregoing, each Restricted Person shall be required to
grant a Lien in favor of Administrative Agent for the benefit of Lenders
encumbering such Restricted Person's ownership interest in any Unrestricted
Subsidiary; provided, no Security Document granting any such Lien on such

                                       87

<PAGE>

ownership interest in such Unrestricted Subsidiary shall restrict or limit the
ownership or operation of such Unrestricted Subsidiary except as otherwise
restricted or limited herein.

         Section 6.15.   Perfection and Protection of Security Interests and
Liens. Each Restricted Person will from time to time deliver to Administrative
Agent any financing statements, continuation statements, extension agreements
and other documents, properly completed and executed (and acknowledged when
required) by Restricted Persons in form and substance satisfactory to
Administrative Agent, which Administrative Agent requests for the purpose of
perfecting, confirming, or protecting any Liens or other rights in Collateral
securing any Obligations.

         Section 6.16.   Bank Accounts; Offset. To secure the repayment of the
Obligations, each Restricted Person hereby grants to each Lender a security
interest, a lien, and a right of offset, each of which shall be in addition to
all other interests, liens, and rights of any Lender at common Law, under the
Loan Documents, or otherwise, and each of which shall be upon and against (a)
any and all moneys, securities or other property (and the proceeds therefrom) of
such Restricted Person now or hereafter held or received by or in transit to any
Lender from or for the account of such Restricted Person, whether for
safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and
all deposits (general or special, time or demand, provisional or final) of such
Restricted Person with any Lender, and (c) any other credits and claims of such
Restricted Person at any time existing against any Lender, including claims
under certificates of deposit. At any time and from time to time during the
continuance of any Event of Default, each Lender is hereby authorized to
foreclose upon, or to offset against the Obligations then due and payable (in
either case without notice to any Restricted Person), any and all items herein
above referred to. The remedies of foreclosure and offset are separate and
cumulative, and either may be exercised independently of the other without
regard to procedures or restrictions applicable to the other.

         Section 6.17.   Guaranties of Subsidiaries. Each Subsidiary of Plains
MLP, and any other Person, other than Unrestricted Subsidiaries, in which any
Subsidiary of Plains MLP owns any capital stock or other equity interest (other
than interests described in clause (d) of the definition of "Permitted
Investments"), now existing or created, acquired or coming into existence after
the date hereof shall, promptly upon request by Administrative Agent, execute
and deliver to Administrative Agent an absolute and unconditional guaranty of
the timely repayment of the Obligations and the due and punctual performance of
the obligations of US Borrower, Term Borrower, and Canadian Revolver Borrower
hereunder (in each case for which such Subsidiary is not a borrower, account
party or similar primary and direct obligor), which guaranty shall be
satisfactory to Administrative Agent in form and substance; provided, with
respect to any such Subsidiary or other Person that is not a Wholly Owned
Subsidiary of Plains MLP, for which consent or approval of third parties is
required for the delivery of such guaranty, such Subsidiary or such other Person
shall not be required to deliver such guaranty, but shall use its commercially
reasonable best efforts, as determined by Administrative Agent, to deliver such
guaranty. Notwithstanding any provision contained herein, in no event shall any
Unrestricted Subsidiary be required to execute and deliver any guaranty for, or
in respect of, the Obligations, or any part thereof. Each Subsidiary of Plains
MLP existing on the date hereof shall duly execute and deliver such a guaranty
prior to the making of any Loan hereunder (in each case for which such
Subsidiary is not a borrower, account party or similar primary and direct
obligor). Plains MLP

                                       88

<PAGE>

will cause each of its Subsidiaries to deliver to Administrative Agent,
simultaneously with its delivery of such a guaranty, written evidence
satisfactory to Administrative Agent and its counsel that such Subsidiary has
taken all corporate, limited liability company or partnership action necessary
to duly approve and authorize its execution, delivery and performance of such
guaranty and any other documents which it is required to execute.

         Section 6.18.   Compliance with Agreements. Each Restricted Person
shall observe, perform or comply with any agreement with any Person or any term
or condition of any instrument, if such agreement or instrument is materially
significant to such Restricted Person or to Restricted Persons on a Consolidated
basis or materially significant to any Guarantor, unless any such failure to so
observe, perform or comply is remedied within the applicable period of grace (if
any) provided in such agreement or instrument.

         Section 6.19.   Rents. By the terms of the various Security Documents,
certain Restricted Persons are and will be assigning to Administrative Agent,
for the benefit of Lender Parties, all of the "Rents" (as defined therein)
accruing to the property covered thereby. Notwithstanding any such assignments,
so long as no Default has occurred and is continuing, (i) such Restricted
Persons may continue to receive and collect from the payors of such Rents all
such Rents, subject, however, to the Liens created under the Security Documents,
which Liens are hereby affirmed and ratified, and free and clear of such Liens,
use the proceeds of the Rents, and (ii) the Administrative Agent will not notify
the obligors of such Rents or take any other action to cause proceeds thereof to
be remitted to the Administrative Agent. Upon the occurrence of a Default,
Administrative Agent may exercise all rights and remedies granted under the
Security Documents, including the right to obtain possession of all Rents then
held by such Restricted Persons or to receive directly from the payors of such
Rents all other Rents until such time as such Default is no longer continuing.
If the Administrative Agent shall receive any Rent proceeds from any payor at
any time other than during the continuance of a Default, then it shall notify US
Borrower thereof and (i) upon request and pursuant to the instructions of US
Borrower, it shall, if no Default is then continuing, remit such proceeds to US
Borrower and (ii) at the request and expense of US Borrower, execute and deliver
a letter to such payors confirming Restricted Persons' right to receive and
collect Rents until otherwise notified by Administrative Agent. In no case shall
any failure, whether purposed or inadvertent, by Administrative Agent to collect
directly any such Rents constitute in any way a waiver, remission or release of
any of its rights under the Security Documents, nor shall any release of any
Rents by Administrative Agent to such Restricted Persons constitute a waiver,
remission, or release of any other Rents or of any rights of Administrative
Agent to collect other Rents thereafter.

         Section 6.20.   Working Capital Borrowings. For an economically
meaningful period of time in each Fiscal Year, as reasonably determined by the
General Partner, the aggregate outstanding principal balance of all Working
Capital Borrowings shall be reduced to a relatively small amount as may be
reasonably specified by the General Partner.

                        ARTICLE VII - Negative Covenants

         (e)     Indebtedness under the Marketing Credit Agreement, provided
that the principal amount of loans and face amount of letters of credit
thereunder at any one time outstanding shall not exceed $350,000,000;

         addition, the Secured Debt Coverage Ratio will not be greater than 4.00
         to 1.

As used herein, "Debt Coverage Ratio" means the ratio of (a) Consolidated Funded
Indebtedness to (b) Consolidated EBITDA, and "Secured Debt Coverage Ratio" means
the ratio of (a) Consolidated Secured Indebtedness to (b) Consolidated EBITDA,
in each case for the four Fiscal Quarter period (or other period specified
below) most recently ended prior to the date of determination for which
financial statements contemplated by Section 6.2(a) or (b) are available to
Borrower; provided, for purposes of this Section 7.12, if, since the beginning
of the four Fiscal Quarter period ending on the date for which Consolidated
EBITDA is determined, any Restricted Person shall have made any asset
disposition or acquisition, shall have consolidated or merged with or into any
Person (other than another Restricted Person), or shall have made any
disposition or acquisition of a Restricted Person or disposition or acquisition
of any partial ownership interest in any other Person, Consolidated EBITDA shall
be calculated giving pro forma effect thereto as if the disposition,
acquisition, consolidation or merger had occurred on the first day of such
period; provided, with respect to any Person not constituting a Subsidiary of
Plains MLP, such pro forma calculation of Consolidated EBITDA, with respect to
any such Person, shall be limited to not more than 75% of (i) such Restricted
Person's ownership interest in such Person times (ii) the difference of such
Person's (A) Consolidated EBITDA minus (B) Interest Expense and capital
expenditures. Such pro forma effect shall include adjustments with respect to
management fees previously distributed with respect to the assets subject to the
acquisition by US Borrower and Canadian Revolver Borrower of all or
substantially all of the assets of CanPet Energy Group (USA) Inc. and CanPet
Energy Group, Inc., respectively and the acquisition of the remaining 50% of the
Manito Pipeline in mid calendar year 2000, and shall otherwise be determined (i)
in good faith by the chief financial officer of Borrower, and (ii) without
giving effect to any anticipated or proposed change in operations, revenues,
expenses or other items included in the computation of Consolidated EBITDA,
except (1) cost reductions specifically identified at the time of disposition,
acquisition, consolidation or merger that are attributable to personnel
reductions, non-recurring maintenance and environmental costs and allocated
corporate overhead, (2) not more than fifty percent (50%) of Consolidated EBITDA
from Plains Terminals that are dedicated to commercial activities of the subject
assets, or (3) with the consent of Majority Lenders.

         Section 7.13. Interest Coverage Ratio. The ratio of (a) Consolidated
EBITDA to (b) Interest Expense for each four Fiscal Quarter period ending on or
after March 31, 2001 will not be less than 2.75 to 1.0.

         Section 7.14. Debt to Capital Ratio. The ratio of (a) all Consolidated
Funded Indebtedness to (b) the sum of Consolidated Funded Indebtedness plus
Consolidated Net Worth will never be greater than:

                  (i)   prior to the Equilon Acquisition Closing Date: 0.70 to 1
         at any time prior to and including December 31, 2002, and 0.65 to 1 at
         any time thereafter; and

                  (ii) on and after the Equilon Acquisition Closing Date: 0.70
         to 1 at any time prior to and including March 30, 2003, and 0.65 to 1

                  (a)  Open Position. No Restricted Person shall at any time

                  aggregate at any time resulting from crude gathering receipts
                  in excess of scheduled quantities, provided that such
                  Restricted Person shall establish an Offsetting Position with
                  respect to such quantities within five business days following
                  identification of such inventory, but in any event not later
                  than the 20/th/ day following the month in which such excess

                       (ii)      Floating Price Contracts to purchase or sell
                  Petroleum Products in the Current Trading Month; provided
                  that, such Floating Price Contracts either (A) have an

                       (iii)     Floating Price Contracts to purchase or sell
                  Petroleum Products to be received or delivered after the
                  Current Trading Month, but within the twelve months following
                  the Current Trading Month provided that (A) such contracts are
                  at the then market price and (B) at any point in time the sum
                  of (x) net realized losses relating to such contracts within
                  the preceding twelve months (excluding Physically Covered Near
                  Term Floating Price Contract Losses) and (y) mark to market
                  exposure relating to such contracts (excluding aggregate mark
                  to market exposure of up to the Dollar Equivalent of

                  does not, at any time, exceed the Dollar Equivalent of
                  $12,500,000.

         As used herein, "Current Trading Month" means (i) with respect to the
         first twenty-five days of any calendar month, the next following
         calendar month and (ii) with respect to the period from the 26/th/ day
         of a calendar month through the last day of such month, the second
         calendar month next following such month (for example, for the period
         from January 26/th/ through February 25/th/, the Current Trading Month
         is March), "Floating Price

                                       100

<PAGE>

         Contract" means (i) a purchase or sale contract based upon a daily
         index such as a posted price or NYMEX price from time to time in effect
         during the delivery month and (ii) a NYMEX spread transaction in which
         the length of time between the offsetting purchase and sale obligations
         do not exceed fourteen months, "Physically Covered Near Term Floating
         Price Contract Losses" means net realized losses incurred in the
         Current Trading Month with respect to Near Term Floating Price
         Contracts entered into prior to such Current Trading Month, for which
         the Company expects to have an offsetting physical position in the
         delivery month originally specified in such Near Term Floating Price
         Contract, and "Near Term Floating Price Contract" means (A) Floating
         Price Contracts within the First Trading Month following the Current
         Trading Month, covering volumes up to 60% of projected crude gathering
         receipts for crude under 30-day evergreen floating price contracts for
         the First Trading Month; and (B) Floating Price Contracts within the
         Second Trading Month following the Current Trading Month, covering
         volumes up to 40% of projected crude gathering receipts for crude under
         30-day evergreen floating price contracts for the Second Trading Month.
         Using the same example as that used for Current Trading Month, the
         First Trading Month following the Current Trading Month for the same
         period is April and the Second Trading Month following the Current
         Trading Month for the same period is May.

                  (b)  Certain Permitted Financial Instruments. No Restricted
         Person will write (i.e. sell) or otherwise participate in any swap,
         collar or similar agreement relating to Petroleum Products, or write
         (i.e. sell) any option, in each case without regard to NYMEX contracts,
         unless, with respect thereto, (i) such Restricted Person has an
         Offsetting Position, and (ii) if the nature of the swap, collar or
         similar agreement obligates, by its terms, the counterparty to perform
         obligations thereunder in favor of a Restricted Person, such
         counterparty (or guarantor to the obligations of such counter-party) at
         the time such financial instrument is made (A) has one or more long
         term unsecured and unenhanced debt obligations rated A or A2 or better,
         respectively, by either Rating Agency, or (B) is a Lender, a "Lender"

         Affiliate of a Lender or "Lender", or (C) is listed in the Disclosure
         Schedule.

                  (c)  NYMEX Transactions. No Restricted Person will enter in to
         any NYMEX contracts that are time-spread positions to each other,
         except (i) in the case where the sale obligation is in the future month
         of the purchase obligation, where both (A) the length of time between
         the purchase and sale contracts does not exceed sixty months and (B)
         the volume does not in the aggregate exceed 50% of the Plains
         Terminals' storage capacity and (ii) in the case where the purchase
         obligation is in the future month of the sale obligation, where the
         length of time between the sale and purchase contracts does not exceed
         fourteen months. No Restricted Person will convert a NYMEX position to
         a physical position by way of an "exchange for physicals" or an
         "alternative delivery procedure" unless the credit extended in
         connection with such physical position would comply with the credit
         requirements of the definition of "Approved Eligible Receivables".

                  transaction with a non-Affiliate of such Restricted Person.

         (c)      Borrowers shall at all times maintain, as between Restricted
                  Persons and Unrestricted Subsidiaries, the separate existence
                  of each Unrestricted Subsidiary.

                  Law, any claim of the Dollar Equivalent of $1,000,000 or more,
                  any notice of potential liability which might be reasonably
                  likely to exceed such amount, or any other material adverse
                  claim thereunder asserted against any Unrestricted Subsidiary

         Restricted Person if a Default or Event of Default is not continuing,
         such designation would not result in a Default or an Event of Default,
         and immediately thereafter such Subsidiary has no outstanding
         Indebtedness. Immediately thereafter, US Borrower shall promptly notify

guaranteeing (a) any Liability of any Borrower or Guarantor or (b) any Liability

         enforceable as warranted in Section 5.5 for any reason other than its
         release or subordination by Administrative Agent;

         permit the holder or holders of such Indebtedness (or a trustee or
         agent on behalf of such holder or holders) to cause, such Indebtedness
         to become due, or to be prepaid in full (whether by redemption,
         purchase, offer to purchase or otherwise), prior to its stated
         maturity;

         with respect to any ERISA Plan, whether or not waived by the Secretary
         of the Treasury or his delegate, or (ii) any Termination Event occurs
         with respect to any ERISA Plan and the then current value of such ERISA

                  (j) GP LLC or General Partner shall default in the payment
         when due of any principal of or interest on any of its Indebtedness in

         note, agreement, indenture or other document evidencing or relating to
         any such Indebtedness shall occur if the effect of such event is to
         cause, or (with the giving of any notice or the lapse of time or both)
         to permit the holder or holders of such Indebtedness (or a trustee or
         agent on behalf of such holder or holders) to cause, such Indebtedness

Upon the occurrence of an Event of Default described in subsection (i)(i),

shall thereupon be immediately due and payable, without demand, presentment,
notice of demand or of dishonor and nonpayment, protest, notice of protest,
notice of intention to accelerate, declaration or notice of acceleration, or any
other notice or declaration of any kind, all of which are hereby expressly
waived by US Borrower, Term Borrower, Canadian Revolver Borrower and each
Restricted Person who at any time ratifies or approves this Agreement. Upon any
such acceleration, any obligation of any Lender to make any further Loans and
any obligation of US LC Issuer or Canadian LC Issuer to issue Letters of Credit
hereunder shall be permanently terminated. During the continuance of any other
Event of Default, Administrative Agent at any time and from time to time may
(and upon written instructions from Majority Lenders, Administrative Agent
shall), without notice to US Borrower, Term Borrower, Canadian Revolver Borrower
or any other Restricted Person, do either or both of the following: (1)
terminate any obligation of Lenders to make Loans hereunder and any obligation
of US LC Issuer or Canadian LC Issuer to issue Letters of Credit hereunder, and
(2) declare any or all of the Obligations immediately due and payable, and all
such Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by US Borrower, Term Borrower, Canadian Revolver

any appropriate proceedings, including proceedings for specific performance of
any covenant or agreement contained in any Loan Document, and each Lender Party
may enforce the payment of any Obligations due it or enforce any other legal or
equitable right which it may have. All rights, remedies and powers conferred
upon Lender Parties under the Loan Documents shall be deemed cumulative and not
exclusive of any other rights, remedies or powers available under the Loan
Documents or at Law or in equity.

                               ARTICLE IX - Agents

         Section 9.1.  Appointment and Authority.

         (a) Each Lender Party hereby irrevocably authorizes Administrative
Agent, and Administrative Agent hereby undertakes, to receive payments of
principal, interest and other amounts due hereunder as specified herein and to
take all other actions and to exercise such powers under the Loan Documents as
are specifically delegated to Administrative Agent by the terms hereof or
thereof, together with all other powers reasonably incidental thereto. The
relationship of Administrative Agent to the other Lender Parties is only that of
one commercial lender acting as administrative agent for others, and nothing in
the Loan Documents shall be construed to constitute Administrative Agent a
trustee or other fiduciary for any Lender Party or any holder of any
participation in a Note nor to impose on Administrative Agent duties and
obligations other than those expressly provided for in the Loan Documents. With
respect to any matters not expressly provided for in the Loan Documents and any
matters which the Loan Documents place within the discretion of Administrative
Agent, Administrative Agent shall not be required to exercise any discretion or
take any action, and it may request instructions from Lenders with respect to
any such matter, in which case it shall be required to act or to refrain from
acting (and shall be fully protected and free from liability to all Lender
Parties in so acting or refraining from acting) upon the instructions of
Majority Lenders (including itself), provided, however, that Administrative
Agent shall not be required to take any action which exposes it to a risk of
personal liability that it considers unreasonable or which is contrary to the
Loan Documents or to applicable Law. Upon receipt by Administrative Agent from
any Borrower of any communication calling for action on the part of Lenders or
upon notice from any Borrower or any Lender to Administrative Agent of any
Default or Event of Default, Administrative Agent shall promptly notify each
other Lender thereof. Each Lender hereby expressly authorizes Administrative
Agent, on behalf of such Lender, to execute and deliver the Intercreditor
Agreement in the form attached hereto as Exhibit H.

         (b) Each Lender Party hereby irrevocably authorizes Canadian
Administration Agent, and Canadian Administration Agent hereby undertakes, to
receive payments of principal, interest and other amounts due hereunder as
specified herein and to take all other actions and to exercise such powers under
the Loan Documents as are specifically delegated to Canadian Administration
Agent by the terms hereof or thereof, together with all other powers reasonably
incidental thereto. The relationship of Canadian Administration Agent to the
other Lender Parties is only that of one commercial lender acting as
administrative agent for others, and nothing in the Loan Documents shall be
construed to constitute Canadian Administration Agent a trustee or other
fiduciary for any Lender Party or any holder of any participation in a Canadian
Revolver Note nor to impose on Canadian Administration Agent duties and
obligations other than those expressly provided for in the Loan Documents. With
respect to any matters not expressly provided for in the Loan Documents and any
matters which the Loan Documents place within the discretion of Canadian
Administration Agent, Canadian Administration Agent shall not be required to
exercise any discretion or take any action, and it may request instructions from
Lenders with respect to any such matter, in which case it shall be required to
act or to refrain from acting (and shall be fully protected and free from
liability to all Lender Parties in so acting

                                      107

<PAGE>

or refraining from acting) upon the instructions of Majority Lenders (including
itself), provided, however, that Canadian Administration Agent shall not be
required to take any action which exposes it to a risk of personal liability
that it considers unreasonable or which is contrary to the Loan Documents or to
applicable Law. Upon receipt by Canadian Administration Agent from any Borrower
of any communication calling for action on the part of Lenders or upon notice
from any Borrower or any Lender to Canadian Administration Agent of any Default
or Event of Default, Canadian Administration Agent shall promptly notify each
other Lender thereof.

         Section 9.2. Exculpation, Administrative Agent's Reliance, Etc. Neither
any Agent nor any of its directors, officers, agents, attorneys, or employees
shall be liable for any action taken or omitted to be taken by any of them under
or in connection with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF ANY
KIND, except that each shall be liable for its own gross negligence or willful
misconduct. Without limiting the generality of the foregoing, each Agent (a) may
treat the payee of any Note as the holder thereof until such Agent receives
written notice of the assignment or transfer thereof in accordance with this
Agreement, signed by such payee and in form satisfactory to such Agent; (b) may
consult with legal counsel (including counsel for any Borrower), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants or experts; (c) makes no warranty or
representation to any other Lender Party and shall not be responsible to any
other Lender Party for any statements, warranties or representations made in or
in connection with the Loan Documents; (d) shall not have any duty to ascertain
or to inquire as to the performance or observance of any of the terms, covenants
or conditions of the Loan Documents on the part of any Restricted Person or to
inspect the property (including the books and records) of any Restricted Person;
(e) shall not be responsible to any other Lender Party for the due execution,
legality, validity, enforceability, genuineness, sufficiency or value of any
Loan Document or any instrument or document furnished in connection therewith;
(f) may rely upon the representations and warranties of each Restricted Person
or Lender Party in exercising its powers hereunder; and (g) shall incur no
liability under or in respect of the Loan Documents by acting upon any notice,
consent, certificate or other instrument or writing (including any facsimile,
telegram, cable or telex) believed by it to be genuine and signed or sent by the
proper Person or Persons.

         Section 9.3. Credit Decisions. Each Lender Party acknowledges that it
has, independently and without reliance upon any other Lender Party, made its
own analysis of US Borrower, Term Borrower, and Canadian Revolver Borrower and
the transactions contemplated hereby and its own independent decision to enter
into this Agreement and the other Loan Documents. Each Lender Party also
acknowledges that it will, independently and without reliance upon any other
Lender Party and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under the Loan Documents.

         Section 9.4. Indemnification. Each Lender agrees to indemnify each
Agent (to the extent not reimbursed by US Borrower, Term Borrower, or Canadian
Revolver Borrower within ten (10) days after demand) from and against such
Lender's Aggregate Percentage Share of any and all liabilities, obligations,
claims, losses, damages, penalties, fines, actions, judgments, suits,
settlements,

                                      108

<PAGE>

costs, expenses or disbursements (including reasonable fees of attorneys,
accountants, experts and advisors) of any kind or nature whatsoever (in this
section collectively called "liabilities and costs") which to any extent (in
whole or in part) may be imposed on, incurred by, or asserted against such Agent
growing out of, resulting from or in any other way associated with any of the
Collateral, the Loan Documents and the transactions and events (including the
enforcement thereof) at any time associated therewith or contemplated therein
(whether arising in contract or in tort or otherwise and including any violation
or noncompliance with any Environmental Laws by any Person or any liabilities or
duties of any Person with respect to Hazardous Materials found in or released
into the environment).

The foregoing indemnification shall apply whether or not such liabilities and
costs are in any way or to any extent owed, in whole or in part, under any claim
or theory of strict liability or caused, in whole or in part, by any negligent
act or omission of any kind by any Agent, provided only that no lender shall be
obligated under this section to indemnify any Agent for that portion, if any, of
any liabilities and costs which is proximately caused by such Agent's own
individual gross negligence or willful misconduct, as determined in a final
judgment. Cumulative of the foregoing, each Lender agrees to reimburse each
Agent promptly upon demand for such Lender's Aggregate Percentage Share of any
costs and expenses to be paid to such Agent by US Borrower, Term Borrower, and
Canadian Revolver Borrower under Section 10.4(a) to the extent that such Agent
is not timely reimbursed for such expenses by such Persons as provided in such
section. As used in this section the term " Agent" shall refer not only to the
Persons designated as such in Section 1.1 but also to each director, officer,
agent, attorney, employee, representative and Affiliate of such Person.

         Section 9.5. Rights as Lender. In its capacity as a Lender, each Agent
shall have the same rights and obligations as any Lender and may exercise such
rights as though it were not an Agent. Each Agent may accept deposits from, lend
money to, act as trustee under indentures of, and generally engage in any kind
of business with any Restricted Person or their Affiliates, all as if it were
not Administrative Agent hereunder and without any duty to account therefor to
any other Lender.

         Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party
agrees that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against US
Borrower, Term Borrower, or Canadian Revolver Borrower or otherwise, obtain
payment of a portion of the aggregate Obligations owed to it which, taking into
account all distributions made by either Agent under Section 3.1, causes such
Lender Party to have received more than it would have received had such payment
been received by either Agent and distributed pursuant to Section 3.1, then (a)
it shall be deemed to have simultaneously purchased and shall be obligated to
purchase interests in the Obligations as necessary to cause all Lender Parties
to share all payments as provided for in Section 3.1, and (b) such other
adjustments shall be made from time to time as shall be equitable to ensure that
such Agent and all Lender Parties share all payments of Obligations as provided
in Section 3.1; provided, however, that nothing herein contained shall in any
way affect the right of any Lender Party to obtain payment (whether by exercise
of rights of banker's lien, set-off or counterclaim or

                                      109

<PAGE>

otherwise) of indebtedness other than the Obligations. Each of US Borrower, Term
Borrower, and Canadian Revolver Borrower expressly consents to the foregoing
arrangements and agrees that any holder of any such interest or other
participation in the Obligations, whether or not acquired pursuant to the
foregoing arrangements, may to the fullest extent permitted by Law and, subject
to the provisions of Section 6.16, exercise any and all rights of banker's lien,
set-off, or counterclaim as fully as if such holder were a holder of the
Obligations in the amount of such interest or other participation. If all or any
part of any funds transferred pursuant to this section is thereafter recovered
from the seller under this section which received the same, the purchase
provided for in this section shall be deemed to have been rescinded to the
extent of such recovery, together with interest, if any, if interest is required
pursuant to the order of a Tribunal to be paid on account of the possession of
such funds prior to such recovery.

         Section 9.7. Investments. Whenever either Agent in good faith
determines that it is uncertain about how to distribute to Lender Parties any
funds which it has received, or whenever either Agent in good faith determines
that there is any dispute among Lender Parties about how such funds should be
distributed, such Agent may choose to defer distribution of the funds which are
the subject of such uncertainty or dispute. If either Agent in good faith
believes that the uncertainty or dispute will not be promptly resolved, or if
either Agent is otherwise required to invest funds pending distribution to
Lender Parties, such Agent shall invest such funds pending distribution; all
interest on any such Investment shall be distributed upon the distribution of
such Investment and in the same proportion and to the same Persons as such
Investment. All moneys received by either Agent for distribution to Lender
Parties (other than to the Person who is Administrative Agent in its separate
capacity as a Lender Party or the Person who is Canadian Administration Agent in
its separate capacity as a Lender Party) shall be held by such Agent pending
such distribution solely as such Agent for such Lender Parties, and such Agent
shall have no equitable title to any portion thereof.

         Section 9.8. Benefit of Article IX. The provisions of this Article are
intended solely for the benefit of Lender Parties, and no Restricted Person
shall be entitled to rely on any such provision or assert any such provision in
a claim or defense against any Lender (other than in relation to the reference
to Section 6.16 contained in Section 9.6 or the right to reasonably approve a
successor Agent under Section 9.9). Lender Parties may waive or amend such
provisions as they desire without any notice to or consent of US Borrower, Term
Borrower, or Canadian Revolver Borrower or any other Restricted Person.

         Section 9.9. Resignation.

         (a) Administrative Agent may resign at any time by giving written
notice thereof to Lenders and US Borrower. Each such notice shall set forth the
date of such resignation. Upon any such resignation Majority Lenders shall have
the right to appoint a successor Administrative Agent, subject to the approval
of US Borrower, unless a Default has occurred and is continuing, which approval
will not be unreasonably withheld. A successor must be appointed for any
retiring Administrative Agent, and such Administrative Agent's resignation shall
become effective when such successor accepts such appointment. If, within thirty
days after the date of the retiring Administrative Agent's resignation, no
successor Administrative Agent has been appointed and has accepted such
appointment, then the retiring Administrative Agent may

                                      110

<PAGE>

appoint a successor Administrative Agent, which shall be a commercial bank
organized or licensed to conduct a banking or trust business under the Laws of
the United States of America or of any state thereof. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, the retiring Administrative Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents. After any
retiring Administrative Agent's resignation hereunder the provisions of this
Article IX shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under the Loan
Documents.

         (b) Canadian Administration Agent may resign at any time by giving
written notice thereof to Lenders and Canadian Revolver Borrower. Each such
notice shall set forth the date of such resignation. Upon any such resignation
Majority Lenders shall have the right to appoint a successor Canadian
Administration Agent, subject to the approval of Canadian Revolver Borrower,
unless a Default has occurred and is continuing, which approval will not be
unreasonably withheld. A successor must be appointed for any retiring Canadian
Administration Agent, and such Canadian Administration Agent's resignation shall
become effective when such successor accepts such appointment. If, within sixty
days after the date of the retiring Canadian Administration Agent's resignation,
no successor Canadian Administration Agent has been appointed and has accepted
such appointment, then the retiring Canadian Administration Agent may appoint a
successor Canadian Administration Agent. Each Canadian Administration Agent
shall be a commercial bank organized or licensed to conduct a banking or trust
business under the Laws of the Dominion of Canada or of any province thereof.
Upon the acceptance of any appointment as Canadian Administration Agent
hereunder by a successor Canadian Administration Agent, the retiring Canadian
Administration Agent shall be discharged from its duties and obligations under
this Agreement and the other Loan Documents. After any retiring Canadian
Administration Agent's resignation hereunder the provisions of this Article IX
shall continue to inure to its benefit as to any actions taken or omitted to be
taken by it while it was Canadian Administration Agent under the Loan Documents.

         Section 9.10. Other Agents. Neither the Syndication Agent nor the
Documentation Agent ("Co-Agents"), in such capacities, shall have any duties or
responsibilities or incur any liabilities in such agency capacities (as opposed
to its capacity as a Lender) under or in connection with this Agreement or under
any of the other Loan Documents. The relationship between US Borrower, Term
Borrower, Canadian Revolver Borrower on the one hand, and the Co-Agents and the
Agents, on the other hand, shall be solely that of borrower and lender. None of
the Co-Agents shall have any fiduciary responsibilities to any of US Borrower,
Term Borrower, Canadian Revolver Borrower or any of its Affiliates. None of the
Co-Agents undertakes any responsibility to any of US Borrower, Term Borrower,
and Canadian Revolver Borrower or any of its respective Affiliates to review or
inform any such Person of any matter in connection with any phase of such
Person's or such Affiliate's business or operations.

         Section 10.1. Waivers and Amendments; Acknowledgments.

<PAGE>

                  (a) Waivers and Amendments. No failure or delay (whether by
         course of conduct or otherwise) by any Lender in exercising any right,
         power or remedy which such Lender Party may have under any of the Loan
         Documents shall operate as a waiver thereof or of any other right,
         power or remedy, nor shall any single or partial exercise by any Lender
         Party of any such right, power or remedy preclude any other or further
         exercise thereof or of any other right, power or remedy. No waiver of
         any provision of any Loan Document and no consent to any departure
         therefrom shall ever be effective unless it is in writing and signed as
         provided below in this section, and then such waiver or consent shall
         be effective only in the specific instances and for the purposes for
         which given and to the extent specified in such writing. No notice to
         or demand on any Restricted Person shall in any case of itself entitle
         any Restricted Person to any other or further notice or demand in
         similar or other circumstances. This Agreement and the other Loan
         Documents set forth the entire understanding between the parties hereto
         with respect to the transactions contemplated herein and therein and
         supersede all prior discussions and understandings with respect to the
         subject matter hereof and thereof, and no waiver, consent, release,
         modification or amendment of or supplement to this Agreement or the
         other Loan Documents shall be valid or effective against any party
         hereto unless the same is in writing and signed by (i) if such party is
         a Borrower, by such Borrower, (ii) if such party is Administrative
         Agent, Canadian Administration Agent, US LC Issuer or Canadian LC
         Issuer, by such party, and (iii) if such party is a Lender, by such
         Lender or by Administrative Agent on behalf of Lenders with the written
         consent of Majority Lenders (which consent has already been given as to
         the termination of the Loan Documents as provided in Section 10.11).
         Notwithstanding the foregoing or anything to the contrary herein,
         Administrative Agent shall not, without the prior consent of each
         individual Lender, execute and deliver on behalf of such Lender any
         waiver or amendment which would: (1) waive any of the conditions
         specified in Article IV (provided that Administrative Agent may in its
         discretion withdraw any request it has made under Section 4.2(f)), (2)
         increase the maximum amount which such Lender is committed hereunder to
         lend, (3) reduce any fees payable to such Lender hereunder, or the
         principal of, or interest on, such Lender's Note, (4) change any date
         fixed for any payment of any such fees, principal or interest, (5)
         amend the definition herein of "Majority Lenders" or otherwise change
         the Aggregate Percentage Shares which are required for Administrative
         Agent, Canadian Administration Agent, Lenders or any of them to take
         any particular action under the Loan Documents, (6) release any
         Borrower from its obligation to pay such Lender's Note or any Guarantor
         from its guaranty of such payment, or (7) release any Collateral,
         except such releases relating to sales of property as permitted under
         Section 7.5.

                  (b) Acknowledgments and Admissions. Each Borrower hereby
         represents, warrants, acknowledges and admits that (i) it has been
         advised by counsel in the negotiation, execution and delivery of the
         Loan Documents to which it is a party, (ii) it has made an independent
         decision to enter into this Agreement and the other Loan Documents to
         which it is a party, without reliance on any representation, warranty,
         covenant or undertaking by Administrative Agent or any other Lender
         Party, whether written, oral or implicit, other than as expressly set
         out in this Agreement or in another Loan Document delivered on or after
         the date hereof, (iii) there are no representations,

                                      112

<PAGE>

         warranties, covenants, undertakings or agreements by any Lender Party
         as to the Loan Documents except as expressly set out in this Agreement
         or in another Loan Document delivered on or after the date hereof, (iv)
         no Lender Party has any fiduciary obligation toward such Borrower with
         respect to any Loan Document or the transactions contemplated thereby,
         (v) the relationship pursuant to the Loan Documents between such
         Borrower and the other Restricted Persons, on one hand, and each Lender
         Party, on the other hand, is and shall be solely that of debtor and
         creditor, respectively, (vi) no partnership or joint venture exists
         with respect to the Loan Documents between any Restricted Person and
         any Lender Party, (vii) Administrative Agent is not such Borrower's
         Administrative Agent, but Administrative Agent for Lenders, (viii)
         should an Event of Default or Default occur or exist, each Lender Party
         will determine in its sole discretion and for its own reasons what
         remedies and actions it will or will not exercise or take at that time,
         (ix) without limiting any of the foregoing, such Borrower is not
         relying upon any representation or covenant by any Lender Party, or any
         representative thereof, and no such representation or covenant has been
         made, that any Lender Party will, at the time of an Event of Default or
         Default, or at any other time, waive, negotiate, discuss, or take or
         refrain from taking any action permitted under the Loan Documents with
         respect to any such Event of Default or Default or any other provision
         of the Loan Documents, and (x) all Lender Parties have relied upon the
         truthfulness of the acknowledgments in this section in deciding to
         execute and deliver this Agreement and to become obligated hereunder.

                  (c) Representation by Lenders. Each Lender hereby represents
         that it will acquire its Notes for its own account in the ordinary
         course of its commercial lending or investing business; however, the
         disposition of such Lender's property shall at all times be and remain
         within its control and, in particular and without limitation, such
         Lender may sell or otherwise transfer its Note, any participation
         interest or other interest in its Note, or any of its other rights and
         obligations under the Loan Documents subject to compliance with
         Sections 10.5(b) through (f), inclusive, and applicable Law.

                  (d) Joint Acknowledgment. This written 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.

                  (e) Annual Rates of Interest. For the purposes of the Interest
         Act (Canada), whenever interest payable pursuant to this Agreement is
         calculated on the basis of a period other than a calendar year (in this
         Section 10.1(e), the "Interest Period"), each rate of interest
         determined pursuant to such calculation expressed as an annual rate is
         equivalent to such rate as so determined multiplied by the actual
         number of days in the calendar year in which the same is to be
         ascertained and divided by the number of days in the Interest Period.

         Section 10.2. Survival of Agreements; Cumulative Nature. All of
Restricted Persons' various representations, warranties, covenants and
agreements in the Loan Documents shall survive the execution and delivery of
this Agreement and the other Loan Documents and the performance hereof and
thereof, including the making or granting of the Loans and the delivery of the
Notes and the other Loan Documents, and shall further survive until all of the
Obligations are paid in full to each Lender Party and all of Lender Parties'
obligations to Borrowers are terminated. All statements and agreements contained
in any certificate or other instrument delivered by any Restricted Person to any
Lender Party under any Loan Document shall be deemed representations and
warranties by Borrowers or agreements and covenants of Borrowers under this
Agreement. The representations, warranties, indemnities, and covenants made by
Restricted Persons in the Loan Documents, and the rights, powers, and privileges
granted to Lender Parties in the Loan Documents, are cumulative, and, except for
expressly specified waivers and consents, no Loan Document shall be construed in
the context of another to diminish, nullify, or otherwise reduce the benefit to
any Lender Party of any such representation, warranty, indemnity, covenant,
right, power or privilege. In particular and without limitation, no exception
set out in this Agreement to any representation, warranty, indemnity, or
covenant herein contained shall apply to any similar representation, warranty,
indemnity, or covenant contained in any other Loan Document, and each such
similar representation, warranty, indemnity, or covenant shall be subject only
to those exceptions which are expressly made applicable to it by the terms of
the various Loan Documents.

         Section 10.3. Notices. All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Administrative Agent may give telephonic notices to the other Lender
Parties), and shall be deemed sufficiently given or furnished if delivered by
personal delivery, by facsimile or other electronic transmission, by delivery
service with proof of delivery, or by registered or certified United States
mail, postage prepaid, to Borrowers and Restricted Persons at the address of
Borrowers specified on the signature pages hereto and to each Lender Party at
its address specified on the signature pages hereto (unless changed by similar
notice in writing given by the particular Person whose address is to be
changed). Any such notice or communication shall be deemed to have been given
(a) in the case of personal delivery or delivery service, as of the date of
first attempted delivery during normal business hours at the address provided
herein, (b) in the case of facsimile or other electronic transmission, upon
receipt, or (c) in the case of registered or certified United States mail, three
days after deposit in the mail; provided, however, that no Borrowing Notice or
Continuation/Conversion Notice shall become effective until actually received by
Administrative Agent.

         Section 10.4. Payment of Expenses; Indemnity.

                  (a)  Payment of Expenses. Whether or not the transactions
         contemplated by this Agreement are consummated, each Borrower will
         promptly (and in any event, within 30 days after any invoice or other
         statement or notice) pay: (i) all transfer, stamp, mortgage,
         documentary or other similar taxes, assessments or charges levied by
         any governmental or revenue authority in respect of this Agreement or
         any of the other Loan Documents or any other document referred to
         herein or therein, (ii) all reasonable costs and expenses incurred by
         or on behalf of Administrative Agent (including attorneys' fees,
         consultants' fees and engineering fees, travel costs and miscellaneous
         expenses) in connection with (1) the negotiation, preparation,
         execution and delivery of the Loan Documents, and any and all consents,
         waivers or other documents or instruments relating thereto, (2) the
         filing, recording, refiling and re-recording of any Loan Documents and
         any other documents or instruments or further assurances required to be
         filed or recorded or refiled or re-recorded by the terms of any Loan
         Document, (3) the borrowings hereunder and other action reasonably
         required in the course of administration hereof, (4) monitoring or
         confirming (or preparation or negotiation of any document related to)
         such Borrower's compliance with any covenants or conditions contained
         in this Agreement or in any Loan Document, and (iii) all reasonable
         costs and expenses incurred by or on behalf of any Lender Party
         (including attorneys' fees, consultants' fees and accounting fees) in
         connection with the defense or enforcement of any of the Loan Documents
         (including this section) or the defense of any Lender Party's exercise
         of its rights thereunder. In addition to the foregoing, until all
         Obligations have been paid in full, each Borrower will also pay or
         reimburse Administrative Agent for all reasonable out-of-pocket costs
         and expenses of Administrative Agent or its agents or employees in
         connection with the continuing administration of the Loans and the
         related due diligence of Administrative Agent, including travel and
         miscellaneous expenses and fees and expenses of Administrative Agent's
         outside counsel, reserve engineers and consultants engaged in
         connection with the Loan Documents.

                  (b)  Indemnity. Each Borrower agrees to indemnify each Lender
         Party, upon demand, from and against any and all liabilities,
         obligations, claims, losses, damages, penalties, fines, actions,
         judgments, suits, settlements, costs, expenses or disbursements
         (including reasonable fees of attorneys, accountants, experts and
         advisors) of any kind or nature whatsoever (in this section
         collectively called "liabilities and costs") which to any extent (in
         whole or in part) may be imposed on, incurred by, or asserted against
         such Lender Party growing out of, resulting from or in any other way
         associated with any of the Collateral, the Loan Documents and the
         transactions and events (including the enforcement or defense thereof)
         at any time associated therewith or contemplated therein (whether
         arising in contract or in tort or otherwise and including any violation
         or noncompliance with any Environmental Laws by any Lender Party or any
         other Person or any liabilities or duties of any Lender Party or any
         other Person with respect to Hazardous Materials found in or released
         into the environment).

The foregoing indemnification shall apply whether or not such liabilities and
costs are in any way or to any extent owed, in whole or in part, under any claim
or theory of strict liability or caused, in whole or in part, by any negligent
act

                                      115

<PAGE>

or omission of any kind by any Lender Party, provided only that no Lender Party
shall be entitled under this section to receive indemnification for that
portion, if any, of any liabilities and costs which is proximately caused by its
own individual gross negligence or willful misconduct, as determined in a final
judgment. If any Person (including any Borrower or any of its Affiliates) ever
alleges such gross negligence or willful misconduct by any Lender Party, the
indemnification provided for in this section shall nonetheless be paid upon
demand, subject to later adjustment or reimbursement, until such time as a court
of competent jurisdiction enters a final judgment as to the extent and effect of
the alleged gross negligence or willful misconduct. As used in this section the
term "Lender Party" shall refer not only to each Person designated as such in
Section 1.1 but also to each director, officer, trustee, agent, attorney,
employee, representative and Affiliate of such Persons.

     Section 10.5. Joint and Several Liability; Parties in Interest;
Assignments; Replacement Notes.

     (a) All Obligations which are incurred by two or more Restricted Persons
shall be their joint and several obligations and liabilities. All grants,
covenants and agreements contained in the Loan Documents shall bind and inure to
the benefit of the parties thereto and their respective successors and permitted
assigns; provided, however, that no Restricted Person may assign or transfer any
of its rights or delegate any of its duties or obligations under any Loan
Document without the prior consent of all Lenders. Neither any Borrower nor any
Affiliates of any Borrower shall directly or indirectly purchase or otherwise
retire any Obligations owed to any Lender nor will any Lender accept any offer
to do so, unless each Lender shall have received substantially the same offer
with respect to the same Percentage Share of the Obligations owed to it. If any
Borrower or any Affiliate of any Borrower at any time purchases some but less
than all of the Obligations owed to all Lender Parties, such purchaser shall not
be entitled to any rights of any Lender under the Loan Documents unless and
until such Borrower or its Affiliates have purchased all of the Obligations.

     (b) No Lender shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person unless the agreement between such Lender and such participant at all
times provides: (i) that such participation exists only as a result of the
agreement between such participant and such Lender and that such transfer does
not give such participant any right to vote as a Lender or any other direct
claims or rights against any Person other than such Lender, (ii) that such
participant is not entitled to payment from any Restricted Person under Sections
3.2 through 3.6 of amounts in excess of those payable to such Lender under such
sections (determined without regard to the sale of such participation), and
(iii) unless such participant is an Affiliate of such Lender, that such
participant shall not be entitled to require such Lender to take any action
under any Loan Document or to obtain the consent of such participant prior to
taking any action under any Loan Document, except for actions which would
require the consent of all Lenders under subsection (a) of Section 10.1. No
Lender selling such a participation shall, as between the other parties hereto
and such Lender, be relieved of any of its obligations hereunder as a result of
the sale of such participation. Each Lender which sells any such participation
to any Person (other than an Affiliate of such Lender) shall give prompt notice
thereof to Administrative Agent and the relevant Borrower; provided,

                                      116

<PAGE>

however, that no liability shall arise if any such Lender fails to give such
notice to such Borrower.

     (c)  Except for sales of participations under the immediately preceding
subsection, no Lender shall make any assignment or transfer of any kind of its
commitments or any of its rights under its Loans or under the Loan Documents,
except for assignments to an Eligible Transferee or, subject to the provisions
of Subsection (g) below, to an affiliate, and then only if such assignment is
made in accordance with the following requirements:

          (i)  In the case of an assignment by a US Lender or Canadian Revolver
     Lender of less than all of its Loans, LC Obligations, and Commitments, each
     such assignment shall apply to a consistent percentage of all Loans and LC
     Obligations owing to the assignor Lender hereunder and to the same
     percentage of the unused portion of the assignor Lender's Commitments, so
     that after such assignment is made both the assignee Lender and the
     assignor Lender shall have a fixed (and not a varying) Percentage Share in
     its Loans and LC Obligations and be committed to make that Percentage Share
     of all future Loans and make that Percentage Share of all future
     participations in LC Obligations, and the Percentage Share of such US
     Commitment or Canadian Revolver Commitment of each of the assignor and
     assignee shall equal or exceed $5,000,000. In the case of an assignment by
     a Term Lender or Term-B Lender of less than all of its respective Term Loan
     or Term-B Loan, after such assignment is made, the Term Loan Percentage
     Share of each of the assignee Term Lender and the assignor Term Lender
     shall equal or exceed 1% or the Term-B Loan Percentage Share of each of the
     assignee Term-B Lender and the assignee Term-B Lender shall equal or exceed
     0.5% (provided that such minimum Term Loan Percentage Share or Term-B Loan
     Percentage Share shall not be required in connection with any assignment by
     any Lender to any fund that invests in loans and is managed by such Lender,
     any affiliate of such Lender, the same fund manager, or any affiliate of
     the same fund manager).

          (ii) The parties to each such assignment shall execute and deliver to
     Administrative Agent (and, as to assignments of Canadian Obligations,
     Canadian Administration Agent), for its acceptance and recording in the
     "Register" (as defined below in this section), an Assignment and Acceptance
     in the form of Exhibit H, appropriately completed, together with the Note
     subject to such assignment and a processing fee payable by such assignor
     Lender (and not at Borrower's expense) to Administrative Agent of $3,500;
     provided, no such processing fee shall be payable in connection with any
     assignment of any Term Loan or Term-B Loan (or portion thereof) by a Lender
     to any fund that invests in loans and is managed by such Lender, any
     affiliate of such Lender, the same fund manager, or any affiliate of the
     same fund manager. Upon such execution, delivery, and payment and upon the
     satisfaction of the conditions set out in such Assignment and Acceptance,
     then (i) the relevant Borrower shall issue new Notes to such assignor and
     assignee upon return of the old Notes to the relevant Borrower, and (ii) as
     of the "Settlement Date" specified in such Assignment and Acceptance the
     assignee thereunder shall be a party hereto and a Lender hereunder and
     Administrative Agent shall thereupon deliver to the relevant Borrower and
     each Lender a revised Schedule 1 hereto showing the revised Percentage
     Shares and total Percentage Shares of such assignor

                                      117

<PAGE>

     Lender and such assignee Lender and the revised Percentage Shares and total
     Percentage Shares of all other Lenders.

          (iii) Each assignee Lender other than an assignee Canadian Revolver
     Lender which is not a United States person (as such term is defined in
     Section 7701(a)(30) of the Code) for Federal income tax purposes, shall (to
     the extent it has not already done so) provide Administrative Agent and
     Borrower with the "Prescribed Forms" referred to in Section 3.7(d).

          (iv)  Each assignee Canadian Revolver Lender shall be a financial
     institution that is (i) not a non-resident of Canada for the purposes of
     the Income Tax Act (Canada); or (ii) an "authorized foreign bank" as
     defined in section 2 of the Bank Act (Canada) and in subsection 248(1) of
     the Income Tax Act (Canada), that is not subject to the restrictions and
     requirements referred to in subsection 524(2) of the Bank Act (Canada) and
     which will receive all amounts paid or credited to it under its Canadian
     Revolver Loans and Canadian Revolver Note in respect of its "Canadian
     banking business" for the purposes of paragraph 212(13.3)(a) of the Income
     Tax Act (Canada).

     (d)  Any Lender may at any time pledge all or any portion of its Loan and
Note (and related rights under the Loan Documents including any portion of its
Note) to any of the twelve (12) Federal Reserve Banks organized under Section 4
of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or enforcement
thereof shall release any such Lender from its obligations under any of the Loan
Documents; provided that all related costs, fees and expenses in connection with
any such pledge shall be for the sole account of such Lender. In addition, any
Term Lender or Term-B Lender may at any time, without consent of US Borrower,
Term Borrower or Administrative Agent, pledge all or any portion of its Term
Loan or Term-B Loan, as the case may be, to any trustee or holder (or other
representative of such holder) (for purpose of this Section 10.5(d), each such
trustee, holder or representative is referred to as a "pledgee") of obligations
owed, or debt securities issued by, such Term Lender or Term-B Lender, as
security for such obligations or debt securities; provided that (i) the
agreement between such Lender and such pledgee at all times provides that such
pledge does not give such pledgee any right to vote as a Lender or any other
direct claims or rights against any Person other than such pledging Term Lender
or Term-B Lender, as applicable, and imposes no obligations on the part of any
of US Borrower, Term Borrower or Administrative Agent, (ii) no such pledge (or
enforcement thereof) shall release any such pledging Term Lender or Term-B
Lender from its obligations under any of the Loan Documents or permit or
authorize any Person to become a Lender unless it has complied with Section
10.5(c), and (iii) all related costs, fees and expenses in connection with any
such pledge shall be for the sole account of such pledging Term Lender or Term-B
Lender.

     (e)  By executing and delivering an Assignment and Acceptance, each
assignee Lender thereunder will be confirming to and agreeing with the relevant
Borrower, Administrative Agent and each other Lender Party that such assignee
understands and agrees to the terms hereof, including Article IX hereof.

     (f)  Administrative Agent (and with respect to Canadian Obligations,
Canadian Administration Agent) shall maintain a copy of each Assignment and
Acceptance and a register

                                      118

<PAGE>

for the recordation of the names and addresses of Lenders and the Percentage
Shares of, and principal amount of the Loans owing to, each Lender from time to
time (in this section called the "Register"). The entries in the Register shall
be conclusive, in the absence of manifest error, and Borrowers and each Lender
Party may treat each Person whose name is recorded in the Register as a Lender
Party hereunder for all purposes. The Register shall be available for inspection
by Borrowers or any Lender Party at any reasonable time and from time to time
upon reasonable prior notice.

     (g)  Any Lender may assign or transfer its commitment or its rights under
its Loans or under the Loan Documents to (i) any Affiliate that is wholly-owned
direct or indirect subsidiary of such Lender or of any Person that wholly owns,
directly or indirectly, such Lender, or (ii) if such Lender is a fund that makes
or invests in bank loans, any other fund that makes or invests in bank loans and
is advised or managed by (A) the same investment advisor as any Lender or (B)
any Affiliate of such investment advisor that is a wholly-owned direct or
indirect subsidiary of any Person that wholly owns, directly or indirectly, such
investment advisor, subject to the following additional conditions (x), (y) and
(z), with respect to assignments pursuant to clause (i) above, and subject to
the following additional conditions (y) and (z) with respect to assignments
pursuant to clause (ii) above:

          (x) any right of such Lender assignor and such assignee to vote as a
     Lender, or any other direct claims or rights against any other Persons,
     shall be uniformly exercised or pursued in the manner that such Lender
     assignor would have so exercised such vote, claim or right if it had not
     made such assignment or transfer;

          (y) such assignee shall not be entitled to payment from any Restricted
     Person under Sections 3.2 through 3.7 of amounts in excess of those payable
     to such Lender assignor under such sections (determined without regard to
     such assignment or transfer); and

          (z) if such Lender assignor is a Lender that assigns or transfers to
     such assignee any of such Lender Commitment, assignee may become primarily
     liable for such Commitment, but such assignment or transfer shall not
     relieve or release such Lender from such Commitment.

     (h)  Upon receipt of an affidavit reasonably satisfactory to Borrower of an
officer of any Lender as to the loss, theft, destruction or mutilation of its
Note or any Security Document which is not of public record, and, in the case of
any such loss, theft, destruction or mutilation, upon cancellation of such Note
or such Security Document, Borrower will execute and deliver, in lieu thereof, a
replacement Note in the same principal amount thereof and otherwise of like
tenor (or each Restricted Person a party to any such Security Document will
execute and deliver a replacement Security Document of like tenor).

     Section 10.6. Confidentiality. Each Lender Party agrees (on behalf of
itself and each of its Affiliates, and each of its and their directors,
officers, agents, attorneys, employees, and representatives) that it (and each
of them) will take all reasonable steps to keep confidential any non-public
information supplied to it by or at the direction of any Restricted Person so
identified

                                      119

<PAGE>

when delivered, provided, however, that this restriction shall not apply to (a)
information which has at the time in question entered the public domain, (b)
information which is required to be disclosed by Law (whether valid or invalid)
of any Tribunal, (c) any disclosure to any Lender Party's Affiliates, auditors,
attorneys, or agents, (d) any disclosure to any other Lender Party or to any
purchaser or prospective purchaser of participations or other interests in any
Loan or Loan Document (provided each such Person first agrees to hold such
information in confidence on the terms provided in this section), or (e) any
disclosure in the course of enforcing its rights and remedies during the
existence of an Event of Default.

     Section 10.7. Governing Law; Submission to Process. Except to the extent
that the Law of another jurisdiction is expressly elected in a Loan Document,
the Loan Documents shall be deemed contracts and instruments made under the Laws
of the State of New York and shall be construed and enforced in accordance with
and governed by the Laws of the State of New York and the Laws of the United
States of America, without regard to principles of conflicts of law. Each
Borrower hereby agrees that any legal action or proceeding against such Borrower
with respect to this Agreement, the Notes or any of the Loan Documents may be
brought in the courts of the State of New York or of the United States of
America for the Southern District of New York as Lender Parties may elect, and,
by execution and delivery hereof, each Borrower accepts and consents for itself
and in respect to its property, generally and unconditionally, the non-exclusive
jurisdiction of the aforesaid courts. Each Borrower agrees that Sections 5-1401
and 5-1402 of the General Obligations Law of the State of New York shall apply
to the Loan Documents and waives any right to stay or to dismiss any action or
proceeding brought before said courts on the basis of forum non conveniens. In
furtherance of the foregoing, each Borrower hereby irrevocably designates and
appoints Corporation Service Company, 80 State Street, Albany, New York 12207,
as agent of such Borrower to receive service of all process brought against such
Borrower with respect to any such proceeding in any such court in New York, such
service being hereby acknowledged by such Borrower to be effective and binding
service in every respect. Copies of any such process so served shall also, if
permitted by Law, be sent by registered mail to the relevant Borrower at its
address set forth below, but the failure of such Borrower to receive such copies
shall not affect in any way the service of such process as aforesaid. Each
Borrower shall furnish to Lender Parties a consent of Corporation Service
Company agreeing to act hereunder prior to the effective date of this agreement.
Nothing herein shall affect the right of Lender Parties to serve process in any
other manner permitted by Law or shall limit the right of Lender Parties to
bring proceedings against any Borrower in the courts of any other jurisdiction.
If for any reason Corporation Service Company shall resign or otherwise cease to
act as any Borrower's agent, each Borrower hereby irrevocably agrees to (a)
immediately designate and appoint a new agent acceptable to Administrative Agent
to serve in such capacity and, in such event, such new agent shall be deemed to
be substituted for Corporation Service Company for all purposes hereof and (b)
promptly deliver to Agent the written consent (in form and substance

                                      120

<PAGE>

Satisfactory to Administrative Agent) of such new agent agreeing to serve in
such capacity.

     Section 10.8.  Waiver of Judgment Interest Act (Alberta). To the extent
permitted by Law, the provisions of the Judgment Interest Act (Alberta) shall
not apply to the Canadian Revolver Notes, the Term Notes, and the other Loan
Documents and are hereby expressly waived by Canadian Revolver Borrower and Term
Borrower.

     Section 10.9.  Deemed Reinvestment Not Applicable. For the purposes of the
Interest Act (Canada), the principle of deemed reinvestment of interest shall
not apply to any interest calculation under the Loan Documents, and the rates of
interest stipulated in this Agreement are intended to be nominal rates and not
effective rates or yields.

     Section 10.10. Limitation on Interest. Lender Parties, Restricted Persons
and any other parties to the Loan Documents intend to contract in strict
compliance with applicable usury Law from time to time in effect. In furtherance
thereof such Persons stipulate and agree that none of the terms and provisions
contained in the Loan Documents shall ever be construed to create a contract to
pay, for the use, forbearance or detention of money, interest in excess of the
maximum amount of interest permitted to be contracted for, charged, or received
by applicable Law from time to time in effect. Neither any Restricted Person nor
any present or future guarantors, endorsers, or other Persons hereafter becoming
liable for payment of any Obligation shall ever be liable for unearned interest
thereon or shall ever be required to pay interest thereon in excess of the
maximum amount that may be lawfully contracted for, charged, or received under
applicable Law from time to time in effect, and the provisions of this section
shall control over all other provisions of the Loan Documents which may be in
conflict or apparent conflict herewith. Lender Parties expressly disavow any
intention to contract for, charge, or receive excessive unearned interest or
finance charges in the event the maturity of any Obligation is accelerated. If
(a) the maturity of any Obligation is accelerated for any reason, (b) any
Obligation is prepaid and as a result any amounts held to constitute interest
are determined to be in excess of the legal maximum, or (c) any Lender or any
other holder of any or all of the Obligations shall otherwise collect moneys
which are determined to constitute interest which would otherwise increase the
interest on any or all of the Obligations to an amount in excess of that
permitted to be contracted for, charged or received by applicable Law then in
effect, then all sums determined to constitute interest in excess of such legal
limit shall, without penalty, be promptly applied to reduce the then outstanding
principal of the related Obligations or, at such Lender's or holder's option,
promptly returned to Borrower or other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable Law, Lender
Parties and Restricted Persons (and any other payors thereof) shall to the
greatest extent permitted under applicable Law, (i) characterize any
non-principal payment as an expense, fee or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable Law in order to
lawfully charge the maximum amount of interest permitted under applicable Law.
In the event applicable Law provides for an interest ceiling under Chapter 303

                                      121

<PAGE>

of the Texas Finance Code (the "Texas Finance Code") as amended, to the extent
that the Texas Finance Code is mandatorily applicable to any Lender, for that
day, the ceiling shall be the "weekly ceiling" as defined in the Texas Finance
Code, provided that if any applicable Law permits greater interest, the Law
permitting the greatest interest shall apply. In no event shall Chapter 346 of
the Texas Finance Code apply to this Agreement or any other Loan Document, or
any transactions or loan arrangement provided or contemplated hereby or thereby.
In no event shall the aggregate "interest" (as defined in section 347 of the
Criminal Code (Canada)) payable under the Loan Documents exceed the maximum
effective annual rate of interest on the "credit advanced" (as defined in that
section) permitted under that section and, if any payment, collection or demand
pursuant to this Agreement in respect of "interest" (as defined in that section)
is determined to be contrary to the provisions of that section, such payment,
collection or demand shall be deemed to have been made by mutual mistake of
Canadian Revolver Borrower, Term Borrower, Canadian Administration Agent,
Canadian Revolver Lenders, and Term Lenders and the amount of such excess
payment or collection shall be refunded to the relevant Borrower. For purposes
of the Canadian Revolver Notes and the Term Notes, the effective annual rate of
interest shall be determined in accordance with generally accepted actuarial
practices and principles over the term applicable thereto on the basis of annual
compounding of the lawfully permitted rate of interest and, in the event of
dispute, a certificate of a Fellow of the Canadian Institute of Actuaries
appointed by Canadian Administration Agent shall be prima facie evidence, for
the purposes of such determination.

     Section 10.11. Termination; Limited Survival. In its sole and absolute
discretion Borrower may at any time that no Obligations are owing or outstanding
elect in a written notice delivered to Administrative Agent to terminate this
Agreement. Upon receipt by Administrative Agent of such a notice, if no
Obligations are then owing or outstanding this Agreement and all other Loan
Documents shall thereupon be terminated and the parties thereto released from
all prospective obligations thereunder. Notwithstanding the foregoing or
anything herein to the contrary, any waivers or admissions made by any
Restricted Person in any Loan Document, any Obligations under Sections 3.2
through 3.6, and any obligations which any Person may have to indemnify or
compensate any Lender Party shall survive any termination of this Agreement or
any other Loan Document. At the request and expense of Borrower, Administrative
Agent shall prepare and execute all necessary instruments to reflect and effect
such termination of the Loan Documents. Administrative Agent is hereby
authorized to execute all such instruments on behalf of all Lenders, without the
joinder of or further action by any Lender.

     Section 10.12. Severability. If any term or provision of any Loan Document
shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

     Section 10.13. Counterparts. This Agreement may be separately executed in
any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

     Section 10.14. Waiver of Jury Trial, Punitive Damages, etc. Restricted
Persons and Lender Parties mutually hereby knowingly, voluntarily, and
intentionally

                                      122

<PAGE>

Waive the right to a trial by jury in respect of any claim based hereon, arising
out of, under or in connection with, this Agreement or any other Loan Documents
contemplated to be executed in connection herewith or any course of conduct,
course of dealings, statements (whether verbal or written) or actions of any
party. This waiver constitutes a material inducement for Lenders to enter into
this agreement and the other Loan Documents and make the Loans. Each Borrower
and each Lender Party hereby further (a) irrevocably waives, to the maximum
extent not prohibited by Law, any right it may have to claim or recover in any
such litigation any "Special Damages," as defined below, (b) certifies that no
party hereto nor any representative or agent or counsel for any party hereto has
represented, expressly or otherwise, or implied that such party would not, in
the event of litigation, seek to enforce the foregoing waivers, and (c)
acknowledges that it has been induced to enter into this Agreement, the other
Loan Documents and the transactions contemplated hereby and thereby by, among
other things, the mutual waivers and certifications contained in this section.
As used in this section, "Special Damages" includes all special, consequential,
exemplary, or punitive damages (regardless of how named), but does not include
any payments or funds which any party hereto has expressly promised to pay or
deliver to any other party hereto.

     Section 10.15. Amendment and Restatement. Upon satisfaction with each of
the conditions set forth in Section 4.3 (except any condition the performance of
which has been waived as a condition to the initial Loan or initial issuance of
a Letter of Credit pursuant to this Agreement), this Agreement shall be deemed
to amend and restate in their entirety the Existing Agreement, at which time
(the "Effective Time") each Lender and each Restricted Person hereby agrees that
(i) the Aggregate Percentage Share of each Lender and the Percentage Share of
each Lender with respect to US Loans, Canadian Revolver Loans, Term Loans and
Term-B Loans shall be as set forth in the definition to this Agreement, (ii) the
loans outstanding under the Existing Agreement and all accrued and unpaid
interest thereon (but not any letters of credit issued and outstanding under the
Existing Agreement and reimbursement obligations with respect thereto, which are
to be deemed to be outstanding under and governed by the Marketing Credit
Agreement as provided therein), and all accrued and unpaid fees and expenses
under the Existing Agreement (the "Outstanding Obligations") shall be deemed to
be outstanding under and governed by this Agreement, and (iii) any "Lender"
under the Existing Agreement that is not a signatory hereto as a Lender under
this Agreement, shall continue to be a Lender, subject to the rights, remedies
and obligations of a "Lender" in this Agreement, and in no event shall be deemed
to have waived or released any of its rights or remedies, nor released from its
obligations under the Existing Agreement, all of which such rights, remedies and
obligations shall continue pursuant to, and as may be amended or restated
pursuant to, the terms hereof.

category of extensions of credit or other assets which include LIBOR

giving effect to such Loans, the Dollar Equivalent of the Facility Usage does
not exceed the lesser of (i) the Maximum Facility Amount and (ii) the Borrowing
Base determined as of the date on which the requested Loans are to be made. The
aggregate amount of all Loans in any Borrowing must be equal to $2,000,000 or
any higher integral multiple of $250,000. Borrower may have no more than five
Borrowings of LIBOR Loans outstanding at any time. The obligation of Borrower to
repay to each Lender the aggregate amount of all Loans made by such Lender,
together with interest accruing in connection therewith, shall be evidenced by a
single promissory note (herein called such Lender's "Note") made by Borrower
payable to the order of such Lender in the form of Exhibit A with appropriate
insertions. The amount of principal owing on any Lender's Note at any given time
shall be the aggregate amount of all Loans theretofore made by such Lender minus
all payments of principal theretofore received by such Lender on such Note.
Interest on each Note shall accrue and be due and payable as provided herein and
therein. Each Note shall be due and payable as provided herein and therein, and
shall be due and payable in full on the last day of the Commitment Period.
Subject to the terms and conditions of this Agreement, Borrower may borrow,
repay, and reborrow hereunder.

         Section 2.2. Requests for New Loans. Borrower must give to
Administrative Agent written notice (or telephonic notice promptly confirmed in
writing) of any requested Borrowing of Loans to be funded by Lenders. Each such
notice constitutes a "Borrowing Notice" hereunder and must:

                                       29

<PAGE>

                  (a) specify (i) the aggregate amount of any such Borrowing of
         Base Rate Loans and the date on which such Base Rate Loans are to be
         advanced, or (ii) the aggregate amount of any such Borrowing of LIBOR
         Loans, the date on which such LIBOR Loans are to be advanced (which
         shall be the first day of the Interest Period which is to apply
         thereto), and the length of the applicable Interest Period; and

                  (b) be received by Administrative Agent not later than 11:00
         a.m., Boston, Massachusetts time, on (i) the day on which any such Base
         Rate Loans are to be made, or (ii) the third Business Day preceding the
         day on which any such LIBOR Loans are to be made.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing Notice" attached hereto as Exhibit B, duly completed. Each
such telephonic request shall be deemed a representation, warranty,
acknowledgment and agreement by Borrower as to the matters which are required to
be set out in such written confirmation. Upon receipt of any such Borrowing
Notice, Administrative Agent shall give each Lender prompt notice of the terms
thereof. If all conditions precedent to such new Loans have been met, each
Lender will on the date requested promptly remit to Administrative Agent at
Administrative Agent's office in Boston, Massachusetts the amount of such
Lender's Loan in immediately available funds, and upon receipt of such funds,
unless to its actual knowledge any conditions precedent to such Loans have been
neither met nor waived as provided herein, Administrative Agent shall promptly
make such Loans available to Borrower. Unless Administrative Agent shall have
received prompt notice from a Lender that such Lender will not make available to
Administrative Agent such Lender's new Loan, Administrative Agent may in its
discretion assume that such Lender has made such Loan available to
Administrative Agent in accordance with this section and Administrative Agent
may if it chooses, in reliance upon such assumption, make such Loan available to
Borrower. If and to the extent such Lender shall not so make its new Loan
available to Administrative Agent, such Lender and Borrower severally agree to
pay or repay to Administrative Agent within three days after demand the amount
of such Loan together with interest thereon, for each day from the date such
amount was made available to Borrower until the date such amount is paid or
repaid to Administrative Agent, with interest at (i) the Federal Funds Rate, if
such Lender is making such payment and (ii) the interest rate applicable at the
time to the other new Loans made on such date, if Borrower is making such
repayment. If neither such Lender nor Borrower pays or repays to Administrative
Agent such amount within such three-day period, Administrative Agent shall be
entitled to recover from Borrower, on demand, in lieu of the interest provided
for in the preceding sentence, interest thereon at the Default Rate, calculated
from the date such amount was made available to Borrower. The failure of any
Lender to make any new Loan to be made by it hereunder shall not relieve any
other Lender of its obligation hereunder, if any, to make its new Loan, but no
Lender shall be responsible for the failure of any other Lender to make any new
Loan to be made by such other Lender.

         Section 2.3. Continuations and Conversions of Existing Loans. Borrower
may make the following elections with respect to Loans already outstanding: to
Convert, in whole or in part, Base Rate Loans to LIBOR Loans, to Convert, in
whole or in part, LIBOR Loans to Base Rate Loans on the last day of the Interest
Period applicable thereto, and to Continue, in whole or in

                                       30

<PAGE>

part, LIBOR Loans beyond the expiration of such Interest Period by designating a
new Interest Period to take effect at the time of such expiration. In making
such elections, Borrower may combine existing Loans made pursuant to separate
Borrowings into one new Borrowing or divide existing Loans made pursuant to one
Borrowing into separate new Borrowings, provided that Borrower may have no more
than five Borrowings of LIBOR Loans outstanding at any time. To make any such
election, Borrower must give to Administrative Agent written notice (or
telephonic notice promptly confirmed in writing) of any such Conversion or
Continuation of existing Loans, with a separate notice given for each new
Borrowing. Each such notice constitutes a "Continuation/Conversion Notice"
hereunder and must:

                  (a)  specify the existing Loans which are to be Continued or
         Converted;

                  (b)  specify (i) the aggregate amount of any Borrowing of Base
         Rate Loans into which such existing Loans are to be Continued or
         Converted and the date on which such Continuation or Conversion is to
         occur, or (ii) the aggregate amount of any Borrowing of LIBOR Loans
         into which such existing Loans are to be Continued or Converted, the
         date on which such Continuation or Conversion is to occur (which shall
         be the first day of the Interest Period which is to apply to such LIBOR
         Loans), and the length of the applicable Interest Period; and

                  (c)  be received by Administrative Agent not later than 11:00
         a.m., Boston, Massachusetts time, on (i) the day on which any such
         Continuation or Conversion to Base Rate Loans is to occur, or (ii) the
         third Business Day preceding the day on which any such Continuation or
         Conversion to LIBOR Loans is to occur.

Each such written request or confirmation must be made in the form and substance
of the "Continuation/Conversion Notice" attached hereto as Exhibit C, duly
completed. Each such telephonic request shall be deemed a representation,
warranty, acknowledgment and agreement by Borrower as to the matters which are
required to be set out in such written confirmation. Upon receipt of any such
Continuation/Conversion Notice, Administrative Agent shall give each Lender
prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be
irrevocable and binding on Borrower. During the continuance of any Default,
Borrower may not make any election to Convert existing Loans into LIBOR Loans or
Continue existing Loans as LIBOR Loans beyond the expiration of their respective
and corresponding Interest Period then in effect. If (due to the existence of a
Default or for any other reason) Borrower fails to timely and properly give any
Continuation/Conversion Notice with respect to a Borrowing of existing LIBOR
Loans at least three days prior to the end of the Interest Period applicable
thereto, such LIBOR Loans, to the extent not prepaid at the end of such Interest
Period, shall automatically be Converted into Base Rate Loans at the end of such
Interest Period. No new funds shall be repaid by Borrower or advanced by any
Lender in connection with any Continuation or Conversion of existing Loans
pursuant to this section, and no such Continuation or Conversion shall be deemed
to be a new advance of funds for any purpose; such Continuations and Conversions
merely constitute a change in the interest rate applicable to already
outstanding Loans.

         Section 2.4.  Use of Proceeds.  Borrower shall use the proceeds of all
Loans to finance Cash and Carry Purchases, as margin deposits not to exceed
$50,000,000 in the aggregate at any

                                       31

time outstanding with respect to Hedging Contracts as permitted pursuant to
Section 7.2(e) and to refinance Matured LC Obligations. Borrower and, with
respect to Canadian Letters of Credit, Borrower or Plains Marketing Canada,
L.P., as the case may be, shall use all Letters of Credit solely for the
purposes specified in Section 2.7(d). In no event shall any Loan or any Letter
of Credit be used (i) to fund distributions by Plains MLP, (ii) directly or
indirectly by any Person for personal, family, household or agricultural
purposes, (iii) for the purpose, whether immediate, incidental or ultimate, of
purchasing, acquiring or carrying any "margin stock" (as such term is defined in
Regulation U promulgated by the Board of Governors of the Federal Reserve
System) or (iv) to extend credit to others directly or indirectly for the
purpose of purchasing or carrying any such margin stock. Borrower represents and
warrants that Borrower is not engaged principally, or as one of Borrower's
important activities, in the business of extending credit to others for the
purpose of purchasing or carrying such margin stock.

         Section 2.5. Optional Prepayments of Loans. Borrower may, upon five
Business Days' notice to Administrative Agent (and Administrative Agent will
promptly give notice to the other Lenders), from time to time and without
premium or penalty prepay the Loans, in whole or in part, so long as the
aggregate amounts of all partial prepayments of principal on the Loans equals
$2,000,000 or any higher integral multiple of $250,000. Each prepayment of
principal under this section shall be accompanied by all interest then accrued
and unpaid on the principal so prepaid. Any principal or interest prepaid
pursuant to this section shall be in addition to, and not in lieu of, all
payments otherwise required to be paid under the Loan Documents at the time of
such prepayment.

         Section 2.6. Mandatory Prepayments. If at any time the Dollar
Equivalent of the Facility Usage exceeds the Borrowing Base (whether due to a
reduction in the Borrowing Base in accordance with this Agreement, or
otherwise), Borrower shall immediately upon demand prepay the principal of the
Loans in an amount at least equal to such excess. If at any time the outstanding
principal balance of the Loans exceed the sum of (i) Hedged Eligible Inventory
plus (ii) the outstanding amount of Accounts resulting from the sale of such
Hedged Eligible Inventory (without duplication), Borrower shall within one
Business Day prepay the principal of the Loans in an amount at least equal to
such excess. Each prepayment of principal under this section shall be
accompanied by all interest then accrued and unpaid on the principal so prepaid.
Any principal or interest prepaid pursuant to this section shall be in addition
to, and not in lieu of, all payments otherwise required to be paid under the
Loan Documents at the time of such prepayment.

         Section 2.7. Letters of Credit. Subject to the terms and conditions
hereof, Borrower and, with respect to Canadian Letters of Credit, Borrower or
Plains Marketing Canada, L.P., may during the Commitment Period request LC
Issuer to issue, amend, or extend the expiration date of, one or more Letters of
Credit, provided that:

                  (a after taking such Letter of Credit into account, the Dollar
         Equivalent of the Facility Usage does not exceed the lesser of (i) the
         Maximum Facility Amount at such time or (ii) the Borrowing Base at such
         time;

                                       32

<PAGE>

                  (b the expiration date of such Letter of Credit is prior to
         the earlier of (i) (A) 70 days, (B) 180 days, if the beneficiary
         thereof is Exxon Mobil Company, or (C) one year, if the beneficiary
         thereof is only the United States Mineral Management Service or other
         federal or state governmental agency regulating Petroleum Products
         purchases, after the date of issuance of such Letter of Credit, and
         (ii) 30 days prior to the end of the Commitment Period;

                  (c the issuance of such Letter of Credit will be in compliance
         with all applicable governmental restrictions, policies, and guidelines
         and will not subject LC Issuer to any cost which is not reimbursable
         under Article III;

                  (d such Letter of Credit is related to the purchase or
         exchange by Borrower or, with respect to any purchase or exchange in
         Canada, by Borrower or by Plains Marketing Canada, L.P., of Petroleum
         Products and is in the form of Exhibit D hereto or such other form and
         terms as shall be acceptable to LC Issuer in its sole and absolute
         discretion and Currently Approved by Majority Lenders, and, if the
         beneficiary thereof is the United States Mineral Management Service,
         after taking such Letter of Credit into account, the aggregate amount
         of LC Obligations in respect to all Letters of Credit naming the United
         States Mineral Management Service as beneficiary does not exceed
         $5,000,000;

                  (e if such Letter of Credit is a Canadian Letter of Credit,
         after taking such Canadian Letter of Credit into account, the Dollar
         Equivalent of the aggregate amount of LC Obligations at such time
         relating to Canadian Letters of Credit does not exceed (1) $50,000,000
         prior to the Murphy Acquisition Closing Date, (2) $80,000,000 during
         the four-month period commencing with the Murphy Acquisition Closing
         Date, and (3) $50,000,000 thereafter; and

                  (f all other conditions in this Agreement to the issuance of
         such Letter of Credit have been satisfied.

LC Issuer will honor any such request if the foregoing conditions (a) through
(f) (in the following Section 2.8 called the "LC Conditions") have been met as
of the date of issuance, amendment, or extension of such Letter of Credit. The
outstanding letters of credit issued by LC Issuer under the Existing Agreement
shall be deemed to be Letters of Credit issued hereunder; Borrower hereby
represents and warrants that the LC Conditions have been met as of the date
hereof with respect to each such Letter of Credit. Borrower or Plains Marketing
Canada, L.P., as the case may be, may request that any Canadian Letter of Credit
be issued in Dollars or in Canadian Dollars, and, subject to the terms and
conditions hereof, LC Issuer will honor such request.

         Section 2.8. Requesting Letters of Credit. Borrower or Plains Marketing
Canada, L.P., as the case may be, must make written application for any Letter
of Credit at least one Business Day before the date on which Borrower or Plains
Marketing Canada, L.P., as the case may be, desires for LC Issuer to issue such
Letter of Credit. By making any such written application, unless otherwise
expressly stated therein, Borrower or Plains Marketing Canada, L.P., as the case
may be, shall be deemed to have represented and warranted that the LC Conditions
described in Section 2.7 will be met as of the date of issuance of such Letter
of Credit. Each such written

                                       33

<PAGE>

application for a Letter of Credit must be made in writing in the form and
substance of Exhibit E, the terms and provisions of which are hereby
incorporated herein by reference (or in such other form as may mutually be
agreed upon by LC Issuer and Borrower or Plains Marketing Canada, L.P., as the
case may be). If all LC Conditions for a Letter of Credit have been met as
described in Section 2.7 on any Business Day before 11:00 a.m, Boston,
Massachusetts time, LC Issuer will issue such Letter of Credit on the same
Business Day at LC Issuer's office in Boston, Massachusetts. If the LC
Conditions are met as described in Section 2.7 on any Business Day on or after
11:00 a.m, Boston, Massachusetts time, LC Issuer will issue such Letter of
Credit on the next succeeding Business Day at LC Issuer's office in Boston,
Massachusetts. If any provisions of any LC Application conflict with any
provisions of this Agreement, the provisions of this Agreement shall govern and
control.

         Section 2.9.  Reimbursement and Participations.

         (a Reimbursement. Each Matured LC Obligation shall constitute a loan by
LC Issuer to Borrower or Plains Marketing Canada, L.P., as the case may be.
Borrower promises to pay to LC Issuer, or to LC Issuer's order, on demand, the
full amount of each Matured LC Obligation (which, in the case of any Letter of
Credit issued in Canadian Dollars, shall as demanded by LC Issuer be payable in
Canadian Dollars or in an amount equal to the equivalent in Dollars of such
amount of Canadian Dollars determined by LC Issuer in accordance with its normal
procedures and after deducting any premium and costs of exchange), including
without limitation all Matured LC Obligations with respect to Canadian Letters
of Credit issued at the request of Plains Marketing Canada, L.P., together with
interest thereon (i) at the Base Rate to and including the second Business Day
after the Matured LC Obligation is incurred and (ii) at the Default Rate on each
day thereafter. In addition, and notwithstanding the foregoing, Plains Marketing
Canada, L.P., pursuant to each LC Application executed by it, shall be obligated
to pay to LC Issuer, or to LC Issuer's order, on demand, the full amount of each
Matured LC Obligation with respect to Canadian Letters of Credit requested by it
(which, in the case of any Letter of Credit issued in Canadian Dollars, shall as
demanded by LC Issuer be payable in Canadian Dollars or in an amount equal to
the equivalent in Dollars of such amount of Canadian Dollars determined by LC
Issuer in accordance with its normal procedures and after deducting any premium
and costs of exchange), together with interest thereon as set forth in the
foregoing sentence (such obligation and Borrower's obligation set forth in the
foregoing sentence with respect to such Canadian Letters of Credit to be joint
and several). Any such reimbursement made by Plains Marketing Canada, L.P.
shall, pursuant to Section 3.7(b) hereof, include all such additional amounts as
are needed to cause the amount received by LC Issuer, after any deduction or
withholding as may be required pursuant to the Income Tax Act (Canada) or other
applicable Canadian Laws, to equal the amount which would have been receivable
in the absence of such deduction or withholding.

         (b Letter of Credit Advances. If the beneficiary of any Letter of
Credit makes a draft or other demand for payment thereunder then Borrower may,
during the interval between the making thereof and the honoring thereof by LC
Issuer, request Lenders to make Loans to Borrower in the amount of such draft or
demand, which Loans shall be made concurrently with LC Issuer's payment of such
draft or demand and shall be immediately used by LC Issuer to repay the amount
of the resulting Matured LC Obligation. Such a request by Borrower shall be made
in compliance with all of the provisions hereof, provided that for the purposes
of the first

                                       34

<PAGE>

sentence of Section 2.1, the amount of such Loans shall be considered, but the
amount of the Matured LC Obligation to be concurrently paid by such Loans shall
not be considered.

         (c Participation by Lenders. LC Issuer irrevocably agrees to grant and
hereby grants to each Lender, and -- to induce LC Issuer to issue Letters of
Credit hereunder -- each Lender irrevocably agrees to accept and purchase and
hereby accepts and purchases from LC Issuer, on the terms and conditions
hereinafter stated and for such Lender's own account and risk an undivided
interest equal to such Lender's Percentage Share of LC Issuer's obligations and
rights under each Letter of Credit issued hereunder and the amount of each
Matured LC Obligation paid by LC Issuer thereunder. Each Lender unconditionally
and irrevocably agrees with LC Issuer that, if a Matured LC Obligation is paid
under any Letter of Credit for which LC Issuer is not reimbursed in full by
Borrower or, with respect to Canadian Letters of Credit requested by Plains
Marketing Canada, L.P., by either Borrower or Plains Marketing Canada, L.P. in
accordance with the terms of this Agreement and the related LC Application
(including any reimbursement by means of concurrent Loans or by the application
of LC Collateral), such Lender shall (in all circumstances and without set-off
or counterclaim) pay to LC Issuer on demand, in immediately available funds at
LC Issuer's address for notices hereunder, such Lender's Percentage Share of
such Matured LC Obligation (or any portion thereof which has not been reimbursed
by Borrower or, with respect to Canadian Letters of Credit requested by Plains
Marketing Canada, L.P., by either Borrower or Plains Marketing Canada, L.P.).
Each Lender's obligation to pay LC Issuer pursuant to the terms of this
subsection is irrevocable and unconditional. If any amount required to be paid
by any Lender to LC Issuer pursuant to this subsection is paid by such Lender to
LC Issuer within three Business Days after the date such payment is due, LC
Issuer shall in addition to such amount be entitled to recover from such Lender,
on demand, interest thereon calculated from such due date at the Federal Funds
Rate. If any amount required to be paid by any Lender to LC Issuer pursuant to
this subsection is not paid by such Lender to LC Issuer within three Business
Days after the date such payment is due, LC Issuer shall in addition to such
amount be entitled to recover from such Lender, on demand, interest thereon
calculated from such due date at the Base Rate.

         (d Distributions to Participants. Whenever LC Issuer has in accordance
with this section received from any Lender payment of such Lender's Percentage
Share of any Matured LC Obligation, if LC Issuer thereafter receives any payment
of such Matured LC Obligation or any payment of interest thereon (whether
directly from Borrower or, with respect to Canadian Letters of Credit requested
by Plains Marketing Canada, L.P., by either Borrower or Plains Marketing Canada,
L.P. or by application of LC Collateral or otherwise, and excluding only
interest for any period prior to LC Issuer's demand that such Lender make such
payment of its Percentage Share), LC Issuer will distribute to such Lender its
Percentage Share of the amounts so received by LC Issuer; provided, however,
that if any such payment received by LC Issuer must thereafter be returned by LC
Issuer, such Lender shall return to LC Issuer the portion thereof which LC
Issuer has previously distributed to it.

         (e Calculations. A written advice setting forth in reasonable detail
the amounts owing under this section, submitted by LC Issuer to Borrower or any
Lender from time to time, shall be conclusive, absent manifest error, as to the
amounts thereof.

          Section 2.10. No Duty to Inquire.

          (a Drafts and Demands. LC Issuer is authorized and instructed to
accept and pay drafts and demands for payment under any Letter of Credit without
requiring, and without responsibility for, any determination as to the existence
of any event giving rise to said draft, either at the time of acceptance or
payment or thereafter. LC Issuer is under no duty to determine the proper
identity of anyone presenting such a draft or making such a demand (whether by
tested telex or otherwise) as the officer, representative or agent of any
beneficiary under any Letter of Credit, and payment by LC Issuer to any such
beneficiary when requested by any such purported officer, representative or
agent is hereby authorized and approved. Borrower releases each Lender Party
from, and agrees to hold each Lender Party harmless and indemnified against, any
liability or claim in connection with or arising out of the subject matter of
this section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR
CLAIM IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, provided only that no
Lender Party shall be entitled to indemnification for that portion, if any, of
any liability or claim which is proximately caused by its own individual gross
negligence or willful misconduct, as determined in a final judgment.

          (b Extension of Maturity. If the maturity of any Letter of Credit is
extended by its terms or by Law or governmental action, if any extension of the
maturity or time for presentation of drafts or any other modification of the
terms of any Letter of Credit is made at the request of Borrower, or if the
amount of any Letter of Credit is increased at the request of Borrower, this
Agreement shall be binding upon all Restricted Persons with respect to such
Letter of Credit as so extended, increased or otherwise modified, with respect
to drafts and property covered thereby, and with respect to any action taken by
LC Issuer, LC Issuer's correspondents, or any Lender Party in accordance with
such extension, increase or other modification.

          (c Transferees of Letters of Credit. If any Letter of Credit provides
that it is transferable, LC Issuer shall have no duty to determine the proper
identity of anyone appearing as transferee of such Letter of Credit, nor shall
LC Issuer be charged with responsibility of any nature or character for the
validity or correctness of any transfer or successive transfers, and payment by
LC Issuer to any purported transferee or transferees as determined by LC Issuer
is hereby authorized and approved, and Borrower releases each Lender Party from,
and agrees to hold each Lender Party harmless and indemnified against, any
liability or claim in connection with or arising out of the foregoing, WHICH
INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY
OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION
OF ANY KIND BY ANY LENDER PARTY, provided only that no Lender Party shall be
entitled to indemnification for that portion, if any, of any liability or claim
which is proximately caused by its own individual gross negligence or willful
misconduct, as determined in a final judgment.

          Section 2.11. LC Collateral.

          (a LC Obligations in Excess of Borrowing Base. If, after the making of
all mandatory prepayments required under Section 2.6, the Dollar Equivalent of
outstanding LC Obligations will exceed the Borrowing Base, then in addition to
prepayment of the entire principal balance of the Loans Borrower will
immediately pay to LC Issuer an amount equal to such excess. LC Issuer will hold
such amount as collateral security for the remaining LC Obligations (all such
amounts held as collateral security for LC Obligations being herein collectively
called "LC Collateral") and the other Obligations, and such collateral may be
applied from time to time to pay Matured LC Obligations or any other Obligations
which are then due and payable. Neither this subsection nor the following
subsection shall, however, limit or impair any rights which LC Issuer may have
under any other document or agreement relating to any Letter of Credit, LC
Collateral or LC Obligation, including any LC Application, or any rights which
any Lender Party may have to otherwise apply any payments by Borrower and any LC
Collateral under Section 3.1.

          (b Acceleration of LC Obligations. If the Obligations or any part
thereof become immediately due and payable pursuant to Section 8.1 then, unless
all Lenders otherwise specifically elect to the contrary (which election may
thereafter be retracted by all Lenders at any time), all LC Obligations shall
become immediately due and payable without regard to whether or not actual
drawings or payments on the Letters of Credit have occurred, and Borrower shall
be obligated to pay to LC Issuer immediately an amount equal to the aggregate
Dollar Equivalent of LC Obligations which are then outstanding to be held as LC
Collateral.

          (c Investment of LC Collateral. Pending application thereof, all LC
Collateral shall be invested by LC Issuer in such Cash Equivalents as LC Issuer
may choose in its sole discretion. All interest on (and other proceeds of) such
Investments shall be reinvested or applied to Matured LC Obligations or other
Obligations which are due and payable. When all Obligations have been satisfied
in full, including all LC Obligations, all Letters of Credit have expired or
been terminated, and all of Borrower's reimbursement obligations in connection
therewith have been satisfied in full, LC Issuer shall release any remaining LC
Collateral. Borrower hereby assigns and grants to LC Issuer for the benefit of
Lenders a continuing security interest in all LC Collateral paid by it to LC
Issuer, all Investments purchased with such LC Collateral, and all proceeds
thereof to secure its Matured LC Obligations and its Obligations under this
Agreement, each Note, and the other Loan Documents, and Borrower agrees that
such LC Collateral, Investments and proceeds shall be subject to all of the
terms and conditions of the Security Documents. Borrower further agrees that LC
Issuer shall have all of the rights and remedies of a secured party under the
UCC with respect to such security interest and that an Event of Default under
this Agreement shall constitute a default for purposes of such security
interest.

          (d Payment of LC Collateral. When Borrower is required to provide LC
Collateral for any reason and fails to do so on the day when required, LC Issuer
or Administrative Agent may without prior notice to Borrower or any other
Restricted Person provide such LC Collateral (whether by application of proceeds
of other Collateral, by transfers from other accounts maintained with LC Issuer,
or otherwise) using any available funds of Borrower or any other Person also
liable to make such payments, and LC Issuer or Administrative Agent will give
notice thereof to Borrower promptly after such application or transfer. Any such
amounts which

                                       37

<PAGE>

are required to be provided as LC Collateral and which are not provided on the
date required shall, for purposes of each Security Document, be considered past
due Obligations owing hereunder, and LC Issuer is hereby authorized to exercise
its respective rights under each Security Document to obtain such amounts.

          Section 2.12. Interest Rates and Fees; Reduction in Commitment.

          (a Interest Rates. Unless the Default Rate shall apply, (i) each Base
Rate Loan shall bear interest on each day outstanding at the Base Rate plus the
Base Rate Margin in effect on such day and (ii) each LIBOR Loan shall bear
interest on each day during the related Interest Period at the related LIBOR
Rate plus the LIBOR Rate Margin in effect on such day. During a Default Rate
Period, all Loans shall bear interest on each day outstanding at the applicable
Default Rate. If an Event of Default based upon Section 8.1(a), Section 8.1(b)
or, with respect to Borrower, based upon Section 8.1(i)(i), (i)(ii) or (i)(iii)
exists and the Loans are not bearing interest at the Default Rate, the past due
principal and past due interest shall bear interest on each day outstanding at
the applicable Default Rate. The interest rate shall change whenever the
applicable Base Rate, the Base Rate Margin, the LIBOR Rate or the LIBOR Rate
Margin changes. In no event shall the interest rate on any Loan exceed the
Highest Lawful Rate.

          (b Commitment Fees. In consideration of each Lender's commitment to
make Loans, Borrower will pay to Administrative Agent for the account of each
Lender a commitment fee determined on a daily basis equal to the Commitment Fee
Rate in effect on such day times such Lender's Percentage Share of the unused
portion of the Maximum Facility Amount on each day during the Commitment Period,
determined for each such day by deducting from the amount of the Maximum
Facility Amount at the end of such day the Dollar Equivalent of the Facility
Usage. This commitment fee shall be due and payable in arrears on the last day
of each Fiscal Quarter and at the end of the Commitment Period. Borrower shall
have the right from time to time to permanently reduce the Maximum Facility
Amount, provided that (i) notice of such reduction is given not less than 2
Business Days prior to such reduction, (ii) the resulting Maximum Facility
Amount is not less than the Dollar Equivalent of the Facility Usage, and (iii)
each partial reduction shall be in an amount at least equal to $500,000 and in
multiples of $100,000 in excess thereof.

          (c Letter of Credit Fees. In consideration of LC Issuer's issuance of
any Letter of Credit, Borrower agrees to pay (i) to Administrative Agent, for
the account of all Lenders in accordance with their respective Percentage
Shares, a letter of credit fee equal to the Letter of Credit Fee Rate applicable
each day times the Dollar Equivalent of the face amount of such Letter of Credit
and (ii) to such LC Issuer for its own account, a letter of credit fronting fee
at a rate equal to one-eighth percent (0.125%) per annum times the Dollar
Equivalent of the face amount of such Letter of Credit. Each such fee will be
calculated on the face amount of each Letter of Credit outstanding on each day
at the above applicable rates and will be payable monthly in arrears on the last
day of each month. In addition, Borrower will pay to LC Issuer a minimum
administrative issuance fee and such other fees and charges customarily charged
by the LC Issuer in respect of any issuance, amendment or negotiation of any
Letter of Credit in accordance with the LC Issuer's published schedule of such
charges effective as of the date of such amendment or negotiation. In addition,
in the event any Canadian Letter of Credit shall at the request of

                                       38

<PAGE>

Borrower or Plains Marketing Canada, L.P., as the case may be, be issued
pursuant to an LC Issuer's Canadian office, Borrower will pay a minimum fee for
such service as customarily charged by such LC Issuer. In addition, and
notwithstanding the foregoing, Plains Marketing Canada, L.P., pursuant to each
LC Application executed by it, shall with respect to Canadian Letters of Credit
requested by it agree to pay such letter of credit fees as set forth in this
Section 2.12(c) (such obligation and Borrower's obligation set forth in this
Section 2.12(c) with respect to such Canadian Letters of Credit to be joint and
several). Any such payment of letter of credit fees made by Plains Marketing
Canada, L.P. shall, pursuant to Section 3.7(b) hereof, include all such
additional amounts as are needed to cause the amount received by Administrative
Agent and LC Issuer, in each case, after any deduction or withholding as may be
required pursuant to the Income Tax Act (Canada) or other applicable Canadian
Laws, to equal the amount which would have been receivable in the absence of
such deduction or withholding.

          (d Administrative Agent's Fees. In addition to all other amounts due
to Administrative Agent under the Loan Documents, Borrower will pay fees to
Administrative Agent as described in a letter agreement of even date herewith
between Administrative Agent and Borrower.

          Section 2.13. Borrowing Base Reporting. The Borrowing Base Reports are
subject to the procedures set forth on Schedule 6.

          Section 2.14. Increase of Maximum Facility Amount and Aggregate
Commitments. (a) So long as no Default or Event of Default has occurred and is
continuing, Borrower may from time to time (i) upon notice to Administrative
Agent and, at Borrower's election, one or more Lenders request that such Lenders
increase their commitments under this credit facility and the Maximum Facility
Amount, and/or (ii) by invitation to one or more Persons consented to by
Administrative Agent, which consent will not be unreasonably withheld, invite
such Persons to become Lenders, so as to increase the aggregate commitments
under this credit facility and the Maximum Facility Amount to an amount not to
exceed $350,000,000. At the time of such notice or invitation, as the case may
be, Borrower (in consultation with, and in cooperation with, Administrative
Agent) shall specify the time period within which each such Lender or invitee,
as applicable, is requested to respond (which shall in no event be less than
five (5) Business Days from the date of such notice or invitation). Upon any
such request to one or more Lenders, each such Lender shall notify
Administrative Agent within the time specified whether or not such Lender agrees
to increase its commitment hereunder and, if so, the amount of such increase.
Any such Lender failing to respond within the time specified shall be deemed to
have declined to increase its commitment. Notwithstanding anything contained
herein, no Lender shall have any obligation whatsoever to increase its
commitment above the amount set forth on such Lender's Lender Schedule.

          (b) Upon any increase in the Maximum Facility Amount, whether by an
increase by one or more Lenders of their commitments hereunder (each an
"Increasing Lender") or by the addition of one or more new lenders electing to
join this credit facility as a Lender (each a "New Lender") pursuant to clause
(a) above, Administrative Agent and Borrower shall determine the effective date
of such increase and shall promptly notify Lenders and New Lenders, if any, of
the final allocation of such increase and the effective date thereof. Such
increase shall become effective as of such effective date upon receipt by
Administrative Agent, at Administrative

                                       39

<PAGE>

Agent's office, of all of the following, each dated as of such effective date:
(i) a certificate of Borrower regarding satisfaction of Section 4.2, (ii) a
consent to such increase, in form and substance reasonably acceptable to
Administrative Agent, executed and delivered by each Guarantor, (iii) a
certificate of Borrower and each Guarantor dated as of such effective date
certifying and attaching resolutions adopted by Borrower or such Guarantor
approving or consenting to such increase, (iv) with respect to any Increasing
Lender, a Commitment Increase Supplement, substantially in the form of Exhibit
L-1, executed and delivered by such Increasing Lender, and a replacement Note
executed and delivered by Borrower reflecting such Increasing Lender's increased
commitment, and (v) with respect to any New Lender, a New Lender Supplement,
substantially in the form of Exhibit L-2, executed and delivered by such New
Lender, and a new Note executed and delivered by Borrower reflecting such New
Lender's commitment.

          (c) Upon the effectiveness of any such increase, each Increasing
Lender shall be bound by and entitled to the rights and benefits of this
Agreement and the other Loan Documents with respect to the full amount of its
commitment as so increased, and each New Lender shall become a Lender for all
purposes and to the same extent as if an original Lender a party hereto and
shall be bound by and entitled to the rights and benefits fo this Agreement and
the other Loan Documents with respect to its commitment. Administrative Agent
shall distribute to Borrower and each Lender an amended Lender Schedule (which
shall be deemed incorporated into this Agreement) reflecting any changes in any
Lender's commitment or Percentage Share resulting from such increase. In the
event any Loans shall remain outstanding as of the effective date of any such
increase in the Maximum Facility Amount and aggregate Lender commitments,
Borrower shall prepay any Loans or portions thereof (and any amounts due under
Section 3.6 in connection with any such prepayment) or make additional
borrowings so that, after giving effect thereto, such outstanding Loans are held
pro rata based on each Lender's revised Percentage Share.

                        ARTICLE III - Payments to Lenders

          Section 3.1. General Procedures. Borrower will make each payment which
it owes under the Loan Documents to Administrative Agent for the account of the
Lender Party to whom such payment is owed in lawful money of the United States
of America, (unless otherwise expressly provided in this Agreement), without
set-off, deduction or counterclaim, and in immediately available funds. Each
such payment must be received by Administrative Agent not later than noon,
Boston, Massachusetts time, on the date such payment becomes due and payable.
Any payment received by Administrative Agent after such time will be deemed to
have been made on the next following Business Day. Should any such payment
become due and payable on a day other than a Business Day, the maturity of such
payment shall be extended to the next succeeding Business Day, and, in the case
of a payment of principal or past due interest, interest shall accrue and be
payable thereon for the period of such extension as provided in the Loan
Document under which such payment is due. Each payment under a Loan Document
shall be due and payable at the place provided therein and, if no specific place
of payment is provided, shall be due and payable at the place of payment of
Administrative Agent's Note. When Administrative Agent collects or receives
money on account of the Obligations, Administrative Agent shall distribute all
money so collected or received, and each Lender Party shall apply all such money
so distributed, as follows:

                  (a first, for the payment of all Obligations which are then
         due (and if such money is insufficient to pay all such Obligations,
         first to any reimbursements due Administrative Agent under Section 6.9
         or 10.4 and then to the partial payment of all other Obligations then
         due in proportion to the amounts thereof, or as Lender Parties shall
         otherwise agree);

                  (b then for the prepayment of amounts owing under the Loan
         Documents (other than principal on the Notes) if so specified by
         Borrower;

                  (c then for the prepayment of principal on the Notes, together
         with accrued and unpaid interest on the principal so prepaid, and then
         held as LC Collateral pursuant to Section 2.11(c); and

                  (d last, for the payment or prepayment of any other
         Obligations.

All payments applied to principal or interest on any Note shall be applied first
to any interest then due and payable, then to principal then due and payable,
and last to any prepayment of principal and accrued interest thereon in
compliance with Sections 2.5 and 2.6, as applicable. All distributions of
amounts described in any of subsections (b), (c) or (d) above shall be made by
Administrative Agent pro rata to each Lender Party then owed Obligations
described in such subsection in proportion to all amounts owed to all Lender
Parties which are described in such subsection; provided that if any Lender then
owes payments to LC Issuer for the purchase of a participation under Section
2.9(c) or to Administrative Agent under Section 9.4, any amounts otherwise
distributable under this section to such Lender shall be deemed to belong to LC
Issuer or Administrative Agent, respectively, to the extent of such unpaid
payments, and Administrative Agent shall apply such amounts to make such unpaid
payments rather than distribute such amounts to such Lender. If any payment on
account of any Obligation is received in Canadian

                                       41

<PAGE>

Dollars, instead of Dollars as required pursuant to this section (whether
voluntarily or pursuant to an order or judgment or the enforcement thereof or
the realization of any security or the liquidation of such Restricted Person or
otherwise howsoever), such payment shall constitute a discharge of such
Obligation only to the extent of the equivalent in Dollars of such amount of
Canadian Dollars determined by Administrative Agent in accordance with its
normal procedures and after deducting any premium and costs of exchange,
determined as of the Business Day next following such receipt. If, for the
purpose of obtaining or enforcing judgment in any court in any Canadian
jurisdiction, it becomes necessary to convert any amount due in Dollars into
Canadian Dollars, then the Dollar Equivalent of such amount shall be determined
on the Business Day following the date such judgment is given, and in any event
Restricted Persons shall continue to be obligated to pay any deficiency owing to
any Lender Party. If any Lender Party receives any payment or payments on
account of the liability of any Restricted Person hereunder pursuant to any
judgment or order in Canadian Dollars, and the Dollar Equivalent of such amount
on the Business Day next following such receipt is less than the full amount of
the Obligation due immediately prior to such judgment or order, then Borrower on
demand shall indemnify and save such Lender Party harmless from and against any
loss, cost or expense arising out of or in connection with such deficiency. The
agreement of indemnity provided for in this Section 3.1 shall constitute an
obligation separate and independent from all other obligations contained in this
Agreement, shall give rise to a separate and independent cause of action, shall
apply irrespective of any indulgence granted by the Lender Parties or any of
them from time to time, and shall continue in full force and effect
notwithstanding any judgment or order for a liquidated sum in respect of an
amount due hereunder or under any judgment or order.

          Section 3.2. Capital Reimbursement. If either (a) the introduction or
implementation of or the compliance with or any change in or in the
interpretation of any Law, or (b) the introduction or implementation of or the
compliance with any request, directive or guideline from any central bank or
other governmental authority (whether or not having the force of Law) affects or
would affect the amount of capital required or expected to be maintained by any
Lender Party or any corporation controlling any Lender Party, then, within five
Business Days after demand by such Lender Party, Borrower will pay to
Administrative Agent for the benefit of such Lender Party, from time to time as
specified by such Lender Party, such additional amount or amounts which such
Lender Party shall determine to be appropriate to compensate such Lender Party
or any corporation controlling such Lender Party in light of such circumstances,
to the extent that such Lender Party reasonably determines that the amount of
any such capital would be increased or the rate of return on any such capital
would be reduced by or in whole or in part based on the existence of the face
amount of such Lender Party's Loans, Letters of Credit, participations in
Letters of Credit or commitments under this Agreement.

          Section 3.3. Increased Cost of LIBOR Loans or Letters of Credit. If
any applicable Law (whether now in effect or hereinafter enacted or promulgated,
including Regulation D) or any interpretation or administration thereof by any
governmental authority charged with the interpretation or administration thereof
(whether or not having the force of Law):

                  (a shall change the basis of taxation of payments to any
         Lender Party of any principal, interest, or other amounts attributable
         to any LIBOR Loan or Letter of Credit or otherwise due under this
         Agreement in respect of any LIBOR Loan or Letter of Credit

                                       42

<PAGE>

         (other than taxes imposed on, or measured by, the overall net income of
         such Lender Party or any Applicable Lending Office of such Lender Party
         by any jurisdiction in which such Lender Party or any such Applicable
         Lending Office is located); or

                  (b shall change, impose, modify, apply or deem applicable any
         reserve, special deposit or similar requirements in respect of any
         LIBOR Loan or any Letter of Credit (excluding those for which such
         Lender Party is fully compensated pursuant to adjustments made in the
         definition of LIBOR Rate) or against assets of, deposits with or for
         the account of, or credit extended by, such Lender Party; or

                  (c shall impose on any Lender Party or the interbank
         eurocurrency deposit market any other condition affecting any LIBOR
         Loan or Letter of Credit, the result of which is to increase the cost
         to any Lender Party of funding or maintaining any LIBOR Loan or of
         issuing any Letter of Credit or to reduce the amount of any sum
         receivable by any Lender Party in respect of any LIBOR Loan or Letter
         of Credit by an amount deemed by such Lender Party to be material,

then such Lender Party shall promptly notify Administrative Agent and Borrower
in writing of the happening of such event and of the amount required to
compensate such Lender Party for such event (on an after-tax basis, taking into
account any taxes on such compensation), whereupon (i) Borrower shall, within
five Business Days after demand therefor by such Lender Party, pay such amount
to Administrative Agent for the account of such Lender Party and (ii) Borrower
may elect, by giving to Administrative Agent and such Lender Party not less than
three Business Days' notice, to Convert all (but not less than all) of any such
LIBOR Loans into Base Rate Loans.

          Section 3.4. Notice; Change of Applicable Lending Office. A Lender
Party shall notify Borrower of any event occurring after the date of this
Agreement that will entitle such Lender Party to compensation under Section 3.2,
3.3 or 3.5 hereof as promptly as practicable, but in any event within 90 days,
after such Lender Party obtains actual knowledge thereof; provided, that (i) if
such Lender Party fails to give such notice within 90 days after it obtains
actual knowledge of such an event, such Lender Party shall, with respect to
compensation payable pursuant to Section 3.2, 3.3 or 3.5 in respect of any costs
resulting from such event, only be entitled to payment under Section 3.2, 3.3 or
3.5 hereof for costs incurred from and after the date 90 days prior to the date
that such Lender Party does give such notice and (ii) such Lender Party will
designate a different Applicable Lending Office for the Loans affected by such
event if such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the sole opinion of such Lender Party, be
disadvantageous to such Lender Party, except that such Lender Party shall have
no obligation to designate an Applicable Lending Office located in the United
States of America. Each Lender Party will furnish to Borrower a certificate
setting forth the basis and amount of each request by such Lender Party for
compensation under Section 3.2, 3.3 or 3.5 hereof.

          Section 3.5. Availability. If (a) any change in applicable Laws, or in
the interpretation or administration thereof of or in any jurisdiction
whatsoever, domestic or foreign, shall make it unlawful or impracticable for any
Lender Party to fund or maintain LIBOR Loans or to issue or participate in
Letters of Credit, or shall materially restrict the authority of any Lender
Party to

                                       43

<PAGE>

purchase or take offshore deposits of dollars (i.e., "eurodollars"), or (b) any
Lender Party determines that matching deposits appropriate to fund or maintain
any LIBOR Loan are not available to it, or (c) any Lender Party determines that
the formula for calculating the LIBOR Rate does not fairly reflect the cost to
such Lender Party of making or maintaining loans based on such rate, then, upon
notice by such Lender Party to Borrower and Administrative Agent, Borrower's
right to elect LIBOR Loans from such Lender Party (or, if applicable, to obtain
Letters of Credit) shall be suspended to the extent and for the duration of such
illegality, impracticability or restriction and all LIBOR Loans of such Lender
Party which are then outstanding or are then the subject of any Borrowing Notice
and which cannot lawfully or practicably be maintained or funded shall
immediately become or remain, or shall be funded as, Base Rate Loans of such
Lender Party. Borrower agrees to indemnify each Lender Party and hold it
harmless against all costs, expenses, claims, penalties, liabilities and damages
which may result from any such change in Law, interpretation or administration.
Such indemnification shall be on an after-tax basis, taking into account any
taxes imposed on the amounts paid as indemnity.

          Section 3.6. Funding Losses. In addition to its other obligations
hereunder, Borrower will indemnify each Lender Party against, and reimburse each
Lender Party on demand for, any loss or expense incurred or sustained by such
Lender Party (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by a Lender
Party to fund or maintain LIBOR Loans), as a result of (a) any payment or
prepayment (whether or not authorized or required hereunder) of all or a portion
of a LIBOR Loan on a day other than the day on which the applicable Interest
Period ends, (b) any payment or prepayment, whether or not required hereunder,
of a Loan made after the delivery, but before the effective date, of a
Continuation/Conversion Notice, if such payment or prepayment prevents such
Continuation/Conversion Notice from becoming fully effective, (c) the failure of
any Loan to be made or of any Continuation/Conversion Notice to become effective
due to any condition precedent not being satisfied or due to any other action or
inaction of any Restricted Person, or (d) any Conversion (whether or not
authorized or required hereunder) of all or any portion of any LIBOR Loan into a
Base Rate Loan or into a different LIBOR Loan on a day other than the day on
which the applicable Interest Period ends. Such indemnification shall be on an
after-tax basis, taking into account any taxes imposed on the amounts paid as
indemnity.

          Section 3.7. Reimbursable Taxes. Borrower covenants and agrees that:

                                       44

<PAGE>

                  (a) Borrower will indemnify each Lender Party against and
         reimburse each Lender Party for all present and future stamp and other
         taxes, duties, levies, imposts, deductions, charges, costs, and
         withholdings whatsoever imposed, assessed, levied or collected on or in
         respect of this Agreement or any LIBOR Loans or Letters of Credit
         (whether or not legally or correctly imposed, assessed, levied or
         collected) including all taxes imposed pursuant to Part XIII of the
         Income Tax Act (Canada) and any withholding or other taxes imposed on
         any Lender Party under Canadian Law, excluding, however, any taxes
         imposed on or measured by the overall net income of Administrative
         Agent or such Lender Party or any Applicable Lending Office of such
         Lender Party by any jurisdiction in which such Lender Party or any such
         Applicable Lending Office is located (all such non-excluded taxes,
         levies, costs and charges being collectively called "Reimbursable
         Taxes" in this section). Such indemnification shall be on an after-tax
         basis, taking into account any taxes imposed on the amounts paid as
         indemnity.

                  (b) All payments on account of the principal of, and interest
         on, each Lender Party's Loans and Note, and all other amounts payable
         by Borrower to any Lender Party hereunder, shall be made in full
         without set-off or counterclaim and shall be made free and clear of and
         without deductions or withholdings of any nature by reason of any
         Reimbursable Taxes, all of which will be for the account of Borrower.
         In the event of Borrower being compelled by Law to make any such
         deduction or withholding from any payment to any Lender Party, Borrower
         shall pay on the due date of such payment, by way of additional
         interest, such additional amounts as are needed to cause the amount
         receivable by such Lender Party after such deduction or withholding to
         equal the amount which would have been receivable in the absence of
         such deduction or withholding. If Borrower should make any deduction or
         withholding as aforesaid, Borrower shall within 60 days thereafter
         forward to such Lender Party an official receipt or other official
         document evidencing payment of such deduction or withholding.

                  (c) If Borrower is ever required to pay any Reimbursable Tax
         with respect to any LIBOR Loan, Borrower may elect, by giving to
         Administrative Agent and such Lender Party not less than three Business
         Days' notice, to Convert all (but not less than all) of any such LIBOR
         Loan into a Base Rate Loan, but such election shall not diminish
         Borrower's obligation to pay all Reimbursable Taxes.

                  (d) Notwithstanding the foregoing provisions of this section,
         Borrower shall be entitled, to the extent it is required to do so by
         Law, to deduct or withhold (and not to make any indemnification or
         reimbursement for) income or other similar taxes imposed by the United
         States of America (other than any portion thereof attributable to a
         change in federal income tax Laws effected after the date hereof) from
         interest, fees or other amounts payable hereunder for the account of
         any Lender Party, other than a Lender Party (i) who is a U.S. person
         for Federal income tax purposes or (ii) who has the Prescribed Forms on
         file with Administrative Agent (with copies provided to Borrower) for
         the applicable year to the extent deduction or withholding of such
         taxes is not required as a result of the filing of such Prescribed
         Forms, provided that if Borrower shall so deduct or withhold any such
         taxes, it shall provide a statement to Administrative Agent and such
         Lender Party, setting forth the amount of such taxes so deducted or
         withheld, the

                                       45

<PAGE>

          applicable rate and any other information or documentation which such
          Lender Party may reasonably request for assisting such Lender Party to
          obtain any allowable credits or deductions for the taxes so deducted
          or withheld in the jurisdiction or jurisdictions in which such Lender
          Party is subject to tax. As used in this section, "Prescribed Forms"
          means such duly executed forms or statements, and in such number of
          copies, which may, from time to time, be prescribed by Law and which,
          pursuant to applicable provisions of (x) an income tax treaty between
          the United States and the country of residence of the Lender Party
          providing the forms or statements, (y) the Code, or (z) any applicable
          rules or regulations thereunder, permit Borrower to make payments
          hereunder for the account of such Lender Party free of such deduction
          or withholding of income or similar taxes.

          Section 3.8 Replacement of Lenders. If any Lender Party seeks
reimbursement for increased costs under Sections 3.2 through 3.7, then within
ninety days thereafter -- provided no Event of Default then exists -- Borrower
shall have the right (unless such Lender Party withdraws its request for
additional compensation) to replace such Lender Party by requiring such Lender
Party to assign its Loans and Notes and its commitments hereunder to an Eligible
Transferee reasonably acceptable to Administrative Agent and to Borrower,
provided that: (i) all Obligations of Borrower owing to such Lender Party being
replaced (including such increased costs and any breakage costs with respect to
any outstanding LIBOR Loans), but excluding principal and accrued interest on
the Notes being assigned) shall be paid in full to such Lender Party
concurrently with such assignment, and (ii) the replacement Eligible Transferee
shall purchase the Note being assigned by paying to such Lender Party a price
equal to the principal amount thereof plus accrued and unpaid interest and
accrued and unpaid commitment fees thereon. In connection with any such
assignment Borrower, Administrative Agent, such Lender Party and the replacement
Eligible Transferee shall otherwise comply with Section 10.5. Notwithstanding
the foregoing rights of Borrower under this section, however, Borrower may not
replace any Lender Party which seeks reimbursement for increased costs under
Section 3.2 through 3.7 unless Borrower is at the same time replacing all Lender
Parties which are then seeking such compensation.

                   ARTICLE V - Representations and Warranties

     To confirm each Lender's understanding concerning Restricted Persons and
Restricted Persons' businesses, properties and obligations and to induce each
Lender to enter into this Agreement and to extend credit hereunder, Plains MLP
and Borrower represent and warrant to each Lender that:

     Section 5.1. No Default. No Restricted Person is in default in the
performance of any of the covenants and agreements contained in any Loan
Document. No event has occurred and is continuing which constitutes a Default.

     Section 5.2. Organization and Good Standing. Each Restricted Person is duly
organized, validly existing and in good standing under the Laws of its
jurisdiction of organization, having all powers required to carry on its
business and enter into and carry out the transactions contemplated hereby. Each
Restricted Person is duly qualified, in good standing, and authorized to do
business in all other jurisdictions within the United States and Canada wherein
the character of the properties owned or held by it or the nature of the
business transacted by it

                                       51

<PAGE>

makes such qualification necessary except where the failure to so qualify would
not cause a Material Adverse Change. Each Restricted Person has taken all
actions and procedures customarily taken in order to enter, for the purpose of
conducting business or owning property, each jurisdiction outside the United
States and Canada wherein the character of the properties owned or held by it or
the nature of the business transacted by it makes such actions and procedures
necessary except where the failure to so qualify would not cause a Material
Adverse Change.

     Section 5.3. Authorization. Each Restricted Person has duly taken all
action necessary to authorize the execution and delivery by it of the Loan
Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder. Borrower is duly authorized to borrow funds hereunder.

     Section 5.4. No Conflicts or Consents. The execution and delivery by the
various Restricted Persons of the Loan Documents to which each is a party, the
performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (i) conflict with any provision of (1) any Law, (2) the
organizational documents of any Restricted Person or any of its Affiliates, or
(3) any agreement, judgment, license, order or permit applicable to or binding
upon any Restricted Person or any of its Affiliates, (ii) result in the
acceleration of any Indebtedness owed by any Restricted Person or any of its
Affiliates, or (iii) result in or require the creation of any Lien upon any
assets or properties of any Restricted Person or any of its Affiliates except as
expressly contemplated in the Loan Documents. Except as expressly contemplated
in the Loan Documents or disclosed in the Disclosure Schedule, no permit,
consent, approval, authorization or order of, and no notice to or filing,
registration or qualification with, any Tribunal or third party is required in
connection with the execution, delivery or performance by any Restricted Person
of any Loan Document or to consummate any transactions contemplated by the Loan
Documents.

     Section 5.5. Enforceable Obligations. This Agreement is, and the other Loan
Documents when duly executed and delivered will be, legal, valid and binding
obligations of each Restricted Person which is a party hereto or thereto,
enforceable in accordance with their terms except as such enforcement may be
limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.

     Section 5.6. Initial Financial Statements. Plains MLP has heretofore
delivered to each Lender true, correct and complete copies of the Initial
Financial Statements. The Initial Financial Statements other than pro forma
financial statements fairly present Plains MLP's Consolidated and consolidating
financial position at the date thereof and the Consolidated and consolidating
results of Plains MLP's operations for the periods thereof, and in the case of
the annual Initial Financial Statements, Consolidated cash flows for the period
thereof. The pro forma Initial Financial Statements fairly present Plains MLP's
pro forma Consolidated and consolidating financial position at the date thereof
and the pro forma Consolidated results of Plains MLP's operations for the period
thereof. Since the date of the annual Initial Financial Statements no Material
Adverse Change has occurred, except as reflected in the quarterly Initial
Financial Statements or in the Disclosure Schedule. All Initial Financial
Statements other than pro forma

                                       52

<PAGE>

financial statements were prepared in accordance with GAAP. All Initial
Financial Statements that are pro forma financial statements were prepared in
accordance with GAAP with such pro forma adjustments as have been accepted by
Administrative Agent.

     Section 5.7.  Other Obligations and Restrictions. No Restricted Person has
any outstanding Liabilities of any kind (including contingent obligations, tax
assessments, and unusual forward or long-term commitments) which are, in the
aggregate, material to Plains MLP or material with respect to Plains MLP's
Consolidated financial condition and not shown in the Initial Financial
Statements, disclosed in the Disclosure Schedule or otherwise permitted under
Section 7.1. Except as shown in the Initial Financial Statements or disclosed in
the Disclosure Schedule, no Restricted Person is subject to or restricted by any
franchise, contract, deed, charter restriction, or other instrument or
restriction which could cause a Material Adverse Change.

     Section 5.8.  Full Disclosure. No certificate, statement or other
information delivered herewith or heretofore by any Restricted Person to any
Lender in connection with the negotiation of this Agreement or in connection
with any transaction contemplated hereby contains any untrue statement of a
material fact or omits to state any material fact necessary to make the
statements contained herein or therein, in light of the circumstances under
which they were made, not misleading as of the date made or deemed made. All
written information furnished after the date hereof by or on behalf of any
Restricted Person to Administrative Agent or any Lender Party in connection with
this Agreement and the other Loan Documents and the transactions contemplated
hereby and thereby will be true, complete and accurate in every material respect
in light of the circumstances in which made, or based on reasonable estimates on
the date as of which such information is stated or certified. There is no fact
known to any Restricted Person that has not been disclosed to each Lender in
writing which could cause a Material Adverse Change.

     Section 5.9.  Litigation. Except as disclosed in the Initial Financial
Statements, in the Disclosure Schedule or pursuant to Section 6.4: (i) there are
no actions, suits or legal, equitable, arbitrative or administrative proceedings
pending, or to the knowledge of any Restricted Person threatened, against any

any which challenge or otherwise pertain to any Restricted Person's title to any
Collateral) before any Tribunal which could reasonably be expected to cause a
Material Adverse Change, and (ii) there are no outstanding judgments,
injunctions, writs, rulings or orders by any such Tribunal against any
Restricted Person or any Restricted Person's stockholders, partners, directors
or officers or affecting any Collateral which could reasonably be expected to

affected by any fire, explosion, accident, strike, lockout or other labor
dispute, drought, storm, hail, earthquake, embargo, act of God or of the public
enemy or other casualty (whether or not covered by insurance), which could cause
a Material Adverse Change.

Schedule, each Restricted Person has all permits, licenses and authorizations
required in connection with the conduct of its businesses, except to the extent
failure to have any such permit, license or authorization could not cause a
Material Adverse Change. Each Restricted Person is in compliance with the terms

compliance with all other limitations, restrictions, conditions, standards,
prohibitions, requirements, obligations, schedules and timetables contained in
any Law, including applicable Environmental Law, or in any regulation, code,

     Section 5.19. Solvency. Upon giving effect to the issuance of the Notes,
the execution of the Loan Documents by Borrower and each Guarantor and the
consummation of the transactions contemplated hereby, (i) Borrower and each
Guarantor will be solvent (as such term is used in applicable bankruptcy,
liquidation, receivership, insolvency or similar Laws), and the sum of
Borrower's and each Guarantor's absolute and contingent liabilities, including
the Obligations or guarantees thereof, shall not exceed the fair market value of
such Restricted Person's assets, and (ii) Borrower's and each Guarantor's
capital should be adequate for the businesses in which such Restricted Person is
engaged and intends to be engaged. Neither Borrower nor any Restricted Person
has incurred (whether under the Loan Documents or otherwise), nor does any
Restricted Person intend to incur or believe that it will incur, debts which
will be beyond its ability to pay as such debts mature.

     Section 5.20. Credit Arrangements. The Disclosure Schedule contains a
complete and correct list, as of the date of this Agreement, of each credit
agreement, loan agreement, indenture, purchase agreement, guaranty or other
arrangement providing for or otherwise relating to any Indebtedness or any
extension of credit (or commitment for any extension of credit) to, or guaranty
by, any Restricted Person, or to which any Restricted Person is subject, other
than the Loan Documents, the Revolver Agreement and the "Loan Documents" as
defined therein, and the aggregate principal or face amount outstanding or which
may become outstanding under each such arrangement is correctly described in the
Disclosure Schedule. No Restricted Person is subject to any restriction under
any credit agreement, loan agreement, indenture, purchase agreement, guaranty or
other arrangement providing for or otherwise relating to any Indebtedness

                                       57

or any extension of credit (or commitment for any extension of credit) to, or
guaranty by, any Affiliate, other than another Restricted Person.

      To conform with the terms and conditions under which each Lender is
willing to have credit outstanding to Borrower, and to induce each Lender to

      Administrative Agent.

      Section 6.3. Other Information and Inspections. In each case subject to
the last sentence of this Section 6.3, each Restricted Person will furnish to
each Lender any information which Administrative Agent or any Lender may from

operations. In each case subject to the last sentence of this Section 6.3, each
Restricted Person will permit representatives appointed by Administrative Agent
(including independent accountants, auditors, agents, attorneys, appraisers and

Restricted Person's property, including its books of account, other books and
records, and any facilities or other business assets, and to make extra copies
therefrom and photocopies and photographs thereof, and to write down and record
any information such representatives obtain, and each Restricted Person shall
permit Administrative Agent or its representatives to investigate and verify the
accuracy of the information furnished to Administrative Agent or any Lender in
connection with the Loan Documents and to discuss all such matters with its
officers, employees and, upon prior notice to Borrower, its representatives.
Without limitation of the foregoing, within one hundred twenty (120) days after
the end of each Fiscal Year, and in addition once during each Fiscal Year, if
requested by Administrative Agent at the instruction of Majority Lenders,
Borrower shall permit commercial financial examiners appointed by Administrative
Agent to conduct a commercial finance examination of the business and assets of
Restricted Persons and in connection with such examination to have full access
to and the right to examine, audit, make abstracts and copies from, and inspect
Restricted Persons' records, files, books of account and all other documents,

                                       60

<PAGE>

reasonable costs and expenses of Administrative Agent associated with any such
examination. Each of the foregoing inspections and examinations shall be made
subject to compliance with applicable safety standards and the same conditions
applicable to any Restricted Person in respect of property of that Restricted
Person on the premises of Persons other than a Restricted Person or an Affiliate
of a Restricted Person, and all information, books and records furnished or
requested to be furnished, or of which copies, photocopies or photographs are
made or requested to be made, all information to be investigated or verified and
all discussions conducted with any officer, employee or representative of any

         Section 6.4. Notice of Material Events and Change of Address. Each
Restricted Person will notify each Lender Party, not later than five (5)
Business Days after any executive officer of Restricted Persons has knowledge
thereof, stating that such notice is being given pursuant to this Agreement, of:

                  (a)  the occurrence of any Material Adverse Change,

                  (b)  the occurrence of any Default,

                  (c)  the acceleration of the maturity of any Indebtedness owed
         by any Restricted Person or of any default by any Restricted Person
         under any indenture, mortgage, agreement, contract or other instrument
         to which any of them is a party or by which any of them or any of their
         properties is bound, if such acceleration or default could cause a
         Material Adverse Change,

                  (d)  the occurrence of any Termination Event,

                  (e)  Under any Environmental Law, any claim of the Dollar
         Equivalent of $1,000,000 or more, any notice of potential liability
         which might be reasonably likely to exceed such amount, or any other
         material adverse claim asserted against any Restricted Person or with
         respect to any Restricted Person's properties taken as a whole, and

                  (f)  the filing of any suit or proceeding, or the assertion in
         writing of a claim against any Restricted Person or with respect to any
         Restricted Person's properties in which an adverse decision reasonably
         could be expected to cause a Material Adverse Change.

Upon the occurrence of any of the foregoing, Restricted Persons will take all
necessary or appropriate steps to remedy promptly any such Material Adverse
Change, Default, acceleration, default, or Termination Event to protect against
any such adverse claim, to defend any such suit or proceeding, and to resolve
all controversies on account of any of the foregoing. Restricted

                                       61

<PAGE>

Persons will also notify Administrative Agent and Administrative Agent's counsel
in writing at least twenty Business Days prior to the date that any Restricted
Person changes its name or the location of its chief executive office or
principal place of business or the place where it keeps its books and records
concerning the Collateral, furnishing with such notice any necessary financing
statement amendments or requesting Administrative Agent and its counsel to
prepare the same.

         Section 6.5. Maintenance of Properties. Each Restricted Person will
maintain, preserve, protect, and keep all Collateral and all other property used
or useful in the conduct of its business in good condition (ordinary wear and
tear excepted) and in compliance with all applicable Laws, and will from time to
time make all repairs, renewals and replacements needed to enable the business
and operations carried on in connection therewith to be promptly and
advantageously conducted at all times.

         Section 6.6. Maintenance of Existence and Qualifications. Each
Restricted Person will maintain and preserve its existence and its rights and
franchises in full force and effect and will qualify to do business in all
states or jurisdictions where required by applicable Law, except where the
failure so to qualify will not cause a Material Adverse Change.

         Section 6.7. Payment of Trade Liabilities, Taxes, etc. Each Restricted
Person will (a) timely file all required tax returns including any extensions;
(b) timely pay all taxes, assessments, and other governmental charges or levies
imposed upon it or upon its income, profits or property; (c) within one hundred
twenty (120) days after the date such goods are delivered or such services are
rendered, pay all Liabilities owed by it on ordinary trade terms to vendors,
suppliers and other Persons providing goods and services used by it in the
ordinary course of its business; (d) pay and discharge when due all other
Liabilities now or hereafter owed by it, other than royalty payments suspended
in the ordinary course of business; and (e) maintain appropriate accruals and
reserves for all of the foregoing in accordance with GAAP. Each Restricted
Person may, however, delay paying or discharging any of the foregoing so long as
it is in good faith contesting the validity thereof by appropriate proceedings,
if necessary, and has set aside on its books adequate reserves therefor which
are required by GAAP.

         Section 6.8. Insurance. Each Restricted Person shall at all times
maintain insurance for its property in accordance with the Insurance Schedule
which insurance shall be by financially sound and reputable insurers. Each
Restricted Person will maintain any additional insurance coverage as described
in the respective Security Documents. Upon demand by Administrative Agent any
insurance policies covering Collateral shall be endorsed (a) to provide for
payment of losses to Administrative Agent as its interests may appear, (b) to
provide that such policies may not be canceled or reduced or affected in any
material manner for any reason without fifteen days prior notice to
Administrative Agent, and (c) to provide for any other matters specified in any
applicable Security Document or which Administrative Agent may reasonably
require. Each Restricted Person shall at all times maintain insurance against
its liability for injury to persons or property in accordance with the Insurance
Schedule, which insurance shall be by financially sound and reputable insurers.
Without limiting the foregoing, each Restricted Person shall at all time
maintain liability insurance in accordance with the Insurance Schedule.

         Section 6.9. Performance on Borrower's Behalf. If any Restricted Person
fails to pay any taxes, insurance premiums, expenses, attorneys' fees or other
amounts it is required to pay under

                                       62

<PAGE>

any Loan Document, Administrative Agent may pay the same after notice of such
payment by Administrative Agent is given to Borrower. Borrower shall immediately
reimburse Administrative Agent for any such payments and each amount paid by
Administrative Agent shall constitute an Obligation owed hereunder which is due
and payable on the date such amount is paid by Administrative Agent.

         Section 6.10. Interest. Borrower hereby promises to each Lender to pay
interest at the Default Rate on all Obligations (including Obligations to pay
fees or to reimburse or indemnify any Lender) which Borrower has in this
Agreement promised to pay to such Lender and which are not paid when due. Such
interest shall accrue from the date such Obligations become due until they are
paid.

         Section 6.11. Compliance with Agreements and Law. Each Restricted
Person will perform all material obligations it is required to perform under the
terms of each indenture, mortgage, deed of trust, security agreement, lease, and
franchise, and each material agreement, contract or other instrument or
obligation to which it is a party or by which it or any of its properties is
bound. Each Restricted Person will conduct its business and affairs in
compliance with all Laws applicable thereto.

safety permits, licenses and other authorizations necessary for its operations
and will maintain such authorizations in full force and effect.

         (b) Each Restricted Person will promptly furnish to Administrative
Agent all written notices of violation, orders, claims, citations, complaints,
penalty assessments, suits or other proceedings received by any Restricted
Person or General Partner, or of which it has notice, pending or threatened
against any Restricted Person, the potential liability of which exceeds the
Dollar Equivalent of $1,000,000 or would cause a Material Adverse Change if
resolved adversely against any Restricted Person, by any governmental authority
with respect to any alleged violation of or non-compliance with any
Environmental Laws or any permits, licenses or authorizations in connection with
its ownership or use of its properties or the operation of its business.

         (c) Each Restricted Person will promptly furnish to Administrative
Agent all requests for information, notices of claim, demand letters, and other
notifications, received by any Restricted Person or General Partner in
connection with its ownership or use of its properties or the conduct of its
business, relating to potential responsibility with respect to any investigation
or clean-up of Hazardous Material at any location, the potential liability of
which exceeds the Dollar Equivalent of $1,000,000 or would cause a Material
Adverse Change if resolved adversely against any Restricted Person.

                                       63

<PAGE>

         Section 6.13. Evidence of Compliance. Subject to the last sentence of
Section 6.3, each Restricted Person will furnish to each Lender at such
Restricted Person's expense all evidence which Administrative Agent from time to
time reasonably requests in writing as to the accuracy and validity of or
compliance with all representations, warranties and covenants made by any
Restricted Person in the Loan Documents, the satisfaction of all conditions
contained therein, and all other matters pertaining thereto.

         Section 6.14. Agreement to Deliver Security Documents. Restricted
Persons will deliver, and will cause each Person, other than Unrestricted
Subsidiaries, in which it owns any capital stock or other equity interest (other
than interests described in clause (d) of the definition of "Permitted
Investments") to deliver, to further secure the Obligations whenever requested
by Administrative Agent in its sole and absolute discretion, deeds of trust,
mortgages, chattel mortgages, security agreements, financing statements and
other Security Documents in form and substance satisfactory to Administrative
Agent for the purpose of granting, confirming, and perfecting first and prior
liens or security interests in any real or personal property now owned or
hereafter acquired by any Restricted Person; provided, with respect to any such
property for which the consent or approval of third parties is required for the
delivery of such Security Documents, Restricted Persons shall not be required to
deliver, or to cause such Person to deliver, such Security Documents with
respect to such property, but shall use their commercially reasonable best
efforts, as determined by Administrative Agent, to deliver, or to cause such
Person to deliver, such Security Documents with respect to such property.
Without limiting the foregoing, each Restricted Person shall be required to
grant a Lien in favor of Administrative Agent for the benefit of Lenders
encumbering such Restricted Person's ownership interest in any Unrestricted
Subsidiary; provided, no Security Document granting any such Lien on such
ownership interest in such Unrestricted Subsidiary shall restrict or limit the
ownership or operation of such Unrestricted Subsidiary except as otherwise
restricted or limited herein.

         Section 6.15. Perfection and Protection of Security Interests and
Liens. Each Restricted Person will from time to time deliver to Administrative
Agent any financing statements, continuation statements, extension agreements
and other documents, properly completed and executed (and acknowledged when
required) by Restricted Persons in form and substance satisfactory to
Administrative Agent, which Administrative Agent requests for the purpose of
perfecting, confirming, or protecting any Liens or other rights in Collateral
securing any Obligations.

         Section 6.16. Bank Accounts; Offset. To secure the repayment of the
Obligations, each Restricted Person hereby grants to each Lender a security
interest, a lien, and a right of offset, each of which shall be in addition to
all other interests, liens, and rights of any Lender at common Law, under the
Loan Documents, or otherwise, and each of which shall be upon and against (a)
any and all moneys, securities or other property (and the proceeds therefrom) of
such Restricted Person now or hereafter held or received by or in transit to any
Lender from or for the account of such Restricted Person, whether for
safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and
all deposits (general or special, time or demand, provisional or final) of such
Restricted Person with any Lender, and (c) any other credits and claims of such
Restricted Person at any time existing against any Lender, including claims
under certificates of deposit. At any time and from time to time during the
continuance of any Event of Default, each Lender is

                                       64

<PAGE>

hereby authorized to foreclose upon, or to offset against the Obligations then
due and payable (in either case without notice to any Restricted Person), any
and all items herein above referred to. The remedies of foreclosure and offset
are separate and cumulative, and either may be exercised independently of the
other without regard to procedures or restrictions applicable to the other.

         Section 6.17. Guaranties of Subsidiaries. Each Subsidiary of Plains
MLP, and any other Person, other than Unrestricted Subsidiaries, in which any
Subsidiary of Plains MLP owns any capital stock or other equity interest (other
than interests described in clause (d) of the definition of "Permitted
Investments"), now existing or created, acquired or coming into existence after
the date hereof shall, promptly upon request by Administrative Agent, execute
and deliver to Administrative Agent an absolute and unconditional guaranty of
the timely repayment of the Obligations and the due and punctual performance of
the obligations of Borrower hereunder (in each case for which such Subsidiary is
not a borrower, account party or similar primary and direct obligor), which
guaranty shall be satisfactory to Administrative Agent in form and substance;
provided, with respect to any such Subsidiary or other Person that is not a
Wholly Owned Subsidiary of Plains MLP, for which consent or approval of third
parties is required for the delivery of such guaranty, such Subsidiary or such
other Person shall not be required to deliver such guaranty, but shall use its
commercially reasonable best efforts, as determined by Administrative Agent, to
deliver such guaranty. Notwithstanding any provision contained herein, in no
event shall any Unrestricted Subsidiary be required to execute and deliver any
guaranty for, or in respect of, the Obligations, or any part thereof. Each
Subsidiary of Plains MLP existing on the date hereof shall duly execute and
deliver such a guaranty prior to the making of any Loan hereunder. Plains MLP
will cause each of its Subsidiaries to deliver to Administrative Agent,
simultaneously with its delivery of such a guaranty, written evidence
satisfactory to Administrative Agent and its counsel that such Subsidiary has
taken all corporate, limited liability company or partnership action necessary
to duly approve and authorize its execution, delivery and performance of such
guaranty and any other documents which it is required to execute.

         Section 6.18. Compliance with Agreements. Each Restricted Person shall
observe, perform or comply with any agreement with any Person or any term or
condition of any instrument, if such agreement or instrument is materially
significant to such Restricted Person or to Restricted Persons on a Consolidated
basis or materially significant to any Guarantor, unless any such failure to so
observe, perform or comply is remedied within the applicable period of grace (if
any) provided in such agreement or instrument.

         Section 6.19. Rents. By the terms of the various Security Documents,
certain Restricted Persons are and will be assigning to Administrative Agent,
for the benefit of Lender Parties, all of the "Rents" (as defined therein)
accruing to the property covered thereby. Notwithstanding any such assignments,
so long as no Default has occurred and is continuing, (i) such Restricted
Persons may continue to receive and collect from the payors of such Rents all
such Rents, subject, however, to the Liens created under the Security Documents,
which Liens are hereby affirmed and ratified, and free and clear of such Liens,
use the proceeds of the Rents, and (ii) the Administrative Agent will not notify
the obligors of such Rents or take any other action to cause proceeds thereof to
be remitted to the Administrative Agent. Upon the occurrence of a Default,
Administrative Agent may exercise all rights and remedies granted under the
Security

                                       65

<PAGE>

Documents, including the right to obtain possession of all Rents then held by
such Restricted Persons or to receive directly from the payors of such Rents all
other Rents until such time as such Default is no longer continuing. If the
Administrative Agent shall receive any Rent proceeds from any payor at any time
other than during the continuance of a Default, then it shall notify Borrower
thereof and (i) upon request and pursuant to the instructions of Borrower, it
shall, if no Default is then continuing, remit such proceeds to the Borrower and
(ii) at the request and expense of Borrower, execute and deliver a letter to
such payors confirming Restricted Persons' right to receive and collect Rents
until otherwise notified by Administrative Agent. In no case shall any failure,
whether purposed or inadvertent, by Administrative Agent to collect directly any
such Rents constitute in any way a waiver, remission or release of any of its
rights under the Security Documents, nor shall any release of any Rents by
Administrative Agent to such Restricted Persons constitute a waiver, remission,
or release of any other Rents or of any rights of Administrative Agent to
collect other Rents thereafter.

         Section 6.20. Operating Practices. Each Restricted Person shall operate
its business in a manner that is consistent with the policies and procedures
approved by the board of directors of General Partner and in effect on, and
delivered to Administrative Agent and Lenders prior to, the date hereof, and
revisions thereto referred to in the following sentence. Borrower shall review
such policies and procedures at least annually, and shall promptly recommend to
the board of directors of General Partner such revisions to such policies and
procedures as may be recommended by Restricted Persons' or, upon consultation
with Borrower and its consultants and at the request of Administrative Agent,
Administrative Agent's third party consultants, to remedy deficiencies in
internal controls, and Borrower shall promptly provide a report to Lenders
regarding such policies and procedures, including such policies and procedures
which the board of directors of General Partner could adopt and has adopted.

                        ARTICLE VII - Negative Covenants

         To conform with the terms and conditions under which each Lender is
willing to have credit outstanding to Borrower, and to induce each Lender to
enter into this Agreement and make the Loans, Plains MLP and Borrower covenant
and agree that until the full and final payment of the Obligations and the

each case without regard to NYMEX contracts, unless, with respect thereto, (i)
such Restricted Person has an Offsetting Position, and (ii) if the nature of the
swap, collar or similar agreement obligates, by its terms, the counterparty to

           promptly following the consummation of such acquisition, be
           distributed back to such investing Restricted Person. In the event
           such Unrestricted Subsidiary shall fail to timely consummate such
           specified acquisition or such specified acquisition shall otherwise
           be abandoned, such Unrestricted Subsidiary shall be deemed to be a
           "Subsidiary" of Plains MLP for purposes of this Agreement and shall
           be subject to the terms and conditions hereof.

or Event of Default is not continuing, such designation would not result in a
Default or an Event of Default, and immediately thereafter such Subsidiary has
no outstanding Indebtedness. Immediately thereafter, Borrower shall promptly
notify the Administrative Agent of such designation and provide to it an
officer's certificate that such designation was made in compliance with this
Section 7.17.

contained in any Loan Document, no Restricted Person shall be prohibited from
guaranteeing (a) any Liability of any Borrower or Guarantor or (b) any Liability

Agent by the terms hereof or thereof, together with all other powers reasonably
incidental thereto. The relationship of Administrative Agent to the other Lender
Parties is only that of one commercial lender acting as administrative agent for
others, and nothing in the Loan Documents shall be construed to constitute
Administrative Agent a trustee or other fiduciary for any Lender Party or any
holder of any participation in a Note nor to impose on Administrative Agent
duties and obligations other than those expressly provided for in the Loan
Documents. With respect to any matters not expressly provided for in the Loan
Documents and any matters which the Loan Documents place within the discretion
of Administrative Agent, Administrative Agent shall not be required to exercise
any discretion or take any action, and it may request instructions from Lenders
with respect to any such matter, in which case it shall be required to act or to
refrain from acting (and shall be fully protected and free from liability to all
Lender Parties in so acting or refraining from acting) upon the instructions of
Majority Lenders (including itself), provided, however, that Administrative
Agent shall not be required to take any action which exposes it to a risk of
personal liability that it considers unreasonable or which is contrary to the
Loan Documents or to applicable Law. Upon receipt by Administrative Agent from
Borrower of any communication calling for action on the part of Lenders or upon
notice from Borrower or any Lender to Administrative Agent of any Default or
Event of Default, Administrative Agent shall promptly notify each other Lender
thereof. Each Lender hereby expressly authorizes Administrative Agent, on behalf
of such Lender, to execute and deliver the Intercreditor Agreement in the form
attached hereto as Exhibit K.

         Section 9.2. Exculpation, Administrative Agent's Reliance, Etc. Neither
Administrative Agent nor any of its directors, officers, agents, attorneys, or
employees shall be liable for any action taken or omitted to be taken by any of
them under or in connection with the Loan Documents, INCLUDING THEIR NEGLIGENCE
OF ANY KIND, except that each shall be liable for its own gross negligence or
willful misconduct. Without limiting the generality of the foregoing,
Administrative Agent (a) may treat the payee of any Note as the holder thereof
until Administrative Agent receives written notice of the assignment or transfer
thereof in accordance with this Agreement, signed by such payee and in form
satisfactory to Administrative Agent; (b) may consult with legal counsel
(including counsel for Borrower), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted
to be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts; (c) makes no warranty or representation to any other
Lender Party and shall not be responsible to any other Lender Party for any
statements, warranties or representations made in or in connection with the Loan
Documents; (d) shall not have any duty to ascertain or to inquire as to the
performance or observance of any of the terms, covenants or conditions of the
Loan Documents

                                       83

<PAGE>

on the part of any Restricted Person or to inspect the property (including the
books and records) of any Restricted Person; (e) shall not be responsible to any
other Lender Party for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of any Loan Document or any instrument or
document furnished in connection therewith; (f) may rely upon the
representations and warranties of each Restricted Person or Lender Party in
exercising its powers hereunder; and (g) shall incur no liability under or in
respect of the Loan Documents by acting upon any notice, consent, certificate or
other instrument or writing (including any facsimile, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper Person or Persons.

         Section 9.3. Credit Decisions. Each Lender Party acknowledges that it
has, independently and without reliance upon any other Lender Party, made its
own analysis of Borrower and the transactions contemplated hereby and its own
independent decision to enter into this Agreement and the other Loan Documents.
Each Lender Party also acknowledges that it will, independently and without
reliance upon any other Lender Party and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under the Loan Documents.

         Section 9.4. Indemnification. Each Lender agrees to indemnify
Administrative Agent (to the extent not reimbursed by Borrower within ten (10)
days after demand) from and against such Lender's Percentage Share of any and
all liabilities, obligations, claims, losses, damages, penalties, fines,
actions, judgments, suits, settlements, costs, expenses or disbursements
(including reasonable fees of attorneys, accountants, experts and advisors) of
any kind or nature whatsoever (in this section collectively called "liabilities
and costs") which to any extent (in whole or in part) may be imposed on,
incurred by, or asserted against Administrative Agent growing out of, resulting
from or in any other way associated with any of the Collateral, the Loan
Documents and the transactions and events (including the enforcement thereof) at
any time associated therewith or contemplated therein (whether arising in
contract or in tort or otherwise and including any violation or noncompliance
with any Environmental Laws by any Person or any liabilities or duties of any
Person with respect to Hazardous Materials found in or released into the
environment).

The foregoing indemnification shall apply whether or not such liabilities and
costs are in any way or to any extent owed, in whole or in part, under any claim
or theory of strict liability or caused, in whole or in part, by any negligent
act or omission of any kind by Administrative Agent,

provided only that no Lender shall be obligated under this section to indemnify
Administrative Agent for that portion, if any, of any liabilities and costs
which is proximately caused by Administrative Agent's own individual gross
negligence or willful misconduct, as determined in a final judgment. Cumulative
of the foregoing, each Lender agrees to reimburse Administrative Agent promptly
upon demand for such Lender's Percentage Share of any costs and expenses to be
paid to Administrative Agent by Borrower under Section 10.4(a) to the extent
that

                                       84

<PAGE>

Administrative Agent is not timely reimbursed for such expenses by Borrower as
provided in such section. As used in this section the term "Administrative
Agent" shall refer not only to the Person designated as such in Section 1.1 but
also to each director, officer, agent, attorney, employee, representative and
Affiliate of such Person.

         Section 9.5. Rights as Lender. In its capacity as a Lender,
Administrative Agent shall have the same rights and obligations as any Lender
and may exercise such rights as though it were not Administrative Agent.
Administrative Agent may accept deposits from, lend money to, act as trustee
under indentures of, and generally engage in any kind of business with any
Restricted Person or their Affiliates, all as if it were not Administrative
Agent hereunder and without any duty to account therefor to any other Lender.

         Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party
agrees that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against Borrower
or otherwise, obtain payment of a portion of the aggregate Obligations owed to
it which, taking into account all distributions made by Administrative Agent
under Section 3.1, causes such Lender Party to have received more than it would
have received had such payment been received by Administrative Agent and
distributed pursuant to Section 3.1, then (a) it shall be deemed to have
simultaneously purchased and shall be obligated to purchase interests in the
Obligations as necessary to cause all Lender Parties to share all payments as
provided for in Section 3.1, and (b) such other adjustments shall be made from
time to time as shall be equitable to ensure that Administrative Agent and all
Lender Parties share all payments of Obligations as provided in Section 3.1;
provided, however, that nothing herein contained shall in any way affect the
right of any Lender Party to obtain payment (whether by exercise of rights of
banker's lien, set-off or counterclaim or otherwise) of indebtedness other than
the Obligations. Borrower expressly consents to the foregoing arrangements and
agrees that any holder of any such interest or other participation in the
Obligations, whether or not acquired pursuant to the foregoing arrangements, may
to the fullest extent permitted by Law and, subject to the provisions of Section
6.16, exercise any and all rights of banker's lien, set-off, or counterclaim as
fully as if such holder were a holder of the Obligations in the amount of such
interest or other participation. If all or any part of any funds transferred
pursuant to this section is thereafter recovered from the seller under this
section which received the same, the purchase provided for in this section shall
be deemed to have been rescinded to the extent of such recovery, together with
interest, if any, if interest is required pursuant to the order of a Tribunal to
be paid on account of the possession of such funds prior to such recovery.

         Section 9.7. Investments. Whenever Administrative Agent in good faith
determines that it is uncertain about how to distribute to Lender Parties any
funds which it has received, or whenever Administrative Agent in good faith
determines that there is any dispute among Lender Parties about how such funds
should be distributed, Administrative Agent may choose to defer distribution of
the funds which are the subject of such uncertainty or dispute. If
Administrative Agent in good faith believes that the uncertainty or dispute will
not be promptly resolved, or if Administrative Agent is otherwise required to
invest funds pending distribution to Lender Parties, Administrative Agent shall
invest such funds pending distribution; all interest on any such Investment
shall be distributed upon the distribution of such Investment and in the same
proportion and to the same Persons as such Investment. All moneys received by
Administrative

                                       85

<PAGE>

Agent for distribution to Lender Parties (other than to the Person who is
Administrative Agent in its separate capacity as a Lender Party) shall be held
by Administrative Agent pending such distribution solely as Administrative Agent
for such Lender Parties, and Administrative Agent shall have no equitable title
to any portion thereof.

         Section 9.8. Benefit of Article IX. The provisions of this Article are
intended solely for the benefit of Lender Parties, and no Restricted Person
shall be entitled to rely on any such provision or assert any such provision in
a claim or defense against any Lender (other than in relation to the reference
to Section 6.16 contained in Section 9.6 or the right to reasonably approve a
successor Administrative Agent under Section 9.9). Lender Parties may waive or
amend such provisions as they desire without any notice to or consent of
Borrower or any other Restricted Person.

         Section 9.9. Resignation. Administrative Agent may resign at any time
by giving written notice thereof to Lenders and Borrower. Each such notice shall
set forth the date of such resignation. Upon any such resignation Majority
Lenders shall have the right to appoint a successor Administrative Agent,
subject to the approval of Borrower, unless a Default has occurred and is
continuing, which approval will not be unreasonably withheld. A successor must
be appointed for any retiring Administrative Agent, and such Administrative
Agent's resignation shall become effective when such successor accepts such
appointment. If, within thirty days after the date of the retiring
Administrative Agent's resignation, no successor Administrative Agent has been
appointed and has accepted such appointment, then the retiring Administrative
Agent may appoint a successor Administrative Agent, which shall be a commercial
bank organized or licensed to conduct a banking or trust business under the Laws
of the United States of America or of any state thereof. Upon the acceptance of
any appointment as Administrative Agent hereunder by a successor Administrative
Agent, the retiring Administrative Agent shall be discharged from its duties and
obligations under this Agreement and the other Loan Documents. After any
retiring Administrative Agent's resignation hereunder the provisions of this
Article IX shall continue to inure to its benefit as to any actions taken or
omitted to be taken by it while it was Administrative Agent under the Loan
Documents.

         Section 9.10. Other Agents. Neither the Syndication Agent nor the
Documentation Agent ("Co-Agents"), in such capacities, shall have any duties or
responsibilities or incur any liabilities in such agency capacities (as opposed
to its capacity as a Lender) under or in connection with this Agreement or under
any of the other Loan Documents. The relationship between Borrower, on the one
hand, and the Co-Agents and Administrative Agent, on the other hand, shall be
solely that of borrower and lender. None of the Co-Agents shall have any
fiduciary responsibilities to Borrower or any of its Affiliates. None of the
Co-Agents undertakes any responsibility to Borrower or any of its respective
Affiliates to review or inform Borrower of any matter in connection with any
phase of Borrower's or such Affiliate's business or operations.

                            ARTICLE X - Miscellaneous

         Section 10.1.  Waivers and Amendments; Acknowledgments.

                                       86

<PAGE>

         (a) Waivers and Amendments. No failure or delay (whether by course of
conduct or otherwise) by any Lender in exercising any right, power or remedy
which such Lender Party may have under any of the Loan Documents shall operate
as a waiver thereof or of any other right, power or remedy, nor shall any single
or partial exercise by any Lender Party of any such right, power or remedy
preclude any other or further exercise thereof or of any other right, power or
remedy. No waiver of any provision of any Loan Document and no consent to any
departure therefrom shall ever be effective unless it is in writing and signed
as provided below in this section, and then such waiver or consent shall be
effective only in the specific instances and for the purposes for which given
and to the extent specified in such writing. No notice to or demand on any
Restricted Person shall in any case of itself entitle any Restricted Person to
any other or further notice or demand in similar or other circumstances. This
Agreement and the other Loan Documents set forth the entire understanding
between the parties hereto with respect to the transactions contemplated herein
and therein and supersede all prior discussions and understandings with respect
to the subject matter hereof and thereof, and no waiver, consent, release,
modification or amendment of or supplement to this Agreement or the other Loan
Documents shall be valid or effective against any party hereto unless the same
is in writing and signed by (i) if such party is Borrower, by Borrower, (ii) if
such party is Administrative Agent or LC Issuer, by such party, and (iii) if
such party is a Lender, by such Lender or by Administrative Agent on behalf of
Lenders with the written consent of Majority Lenders (which consent has already
been given as to the termination of the Loan Documents as provided in Section
10.9). Notwithstanding the foregoing or anything to the contrary herein,
Administrative Agent shall not, without the prior consent of each individual
Lender, execute and deliver on behalf of such Lender any waiver or amendment
which would: (1) waive any of the conditions specified in Article IV (provided
that Administrative Agent may in its discretion withdraw any request it has made
under Section 4.2(f)), (2) increase the Percentage Share of any such Lender or
the maximum amount any such Lender is committed to fund in respect of Letter of
Credit Obligations and Loans or subject such Lender to any additional
obligations, (3) reduce any fees payable to such Lender hereunder, or the
principal of, or interest on, such Lender's Note, (4) change any date fixed for
any payment of any such fees, principal or interest, (5) amend the definition
herein of "Borrowing Base" or any of the terms used in that definition, (6)
amend the definition herein of "Majority Lenders" or otherwise change the
aggregate amount of Percentage Shares which is required for Administrative
Agent, Lenders or any of them to take any particular action under the Loan
Documents, (7) release Borrower from its obligation to pay such Lender's Note or
any Guarantor from its guaranty of such payment, or (8) release any Collateral,
except such releases relating to sales of property permitted under Section 7.5.

         (b) Acknowledgments and Admissions. Borrower hereby represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and
the other Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by Administrative Agent or any
other Lender Party, whether written, oral or implicit, other than as expressly
set out in this Agreement or in another Loan Document delivered on or after the
date hereof, (iii) there are no representations, warranties, covenants,
undertakings or agreements by any Lender Party as to the Loan Documents except
as expressly set out in this Agreement or in another Loan Document delivered on
or after the date hereof, (iv) no Lender Party has any fiduciary obligation
toward

                                       87

<PAGE>

Borrower with respect to any Loan Document or the transactions contemplated
thereby, (v) the relationship pursuant to the Loan Documents between Borrower
and the other Restricted Persons, on one hand, and each Lender Party, on the
other hand, is and shall be solely that of debtor and creditor, respectively,
(vi) no partnership or joint venture exists with respect to the Loan Documents
between any Restricted Person and any Lender Party, (vii) Administrative Agent
is not Borrower's Administrative Agent, but Administrative Agent for Lenders,
(viii) should an Event of Default or Default occur or exist, each Lender Party
will determine in its sole discretion and for its own reasons what remedies and
actions it will or will not exercise or take at that time, (ix) without limiting
any of the foregoing, Borrower is not relying upon any representation or
covenant by any Lender Party, or any representative thereof, and no such
representation or covenant has been made, that any Lender Party will, at the
time of an Event of Default or Default, or at any other time, waive, negotiate,
discuss, or take or refrain from taking any action permitted under the Loan
Documents with respect to any such Event of Default or Default or any other
provision of the Loan Documents, and (x) all Lender Parties have relied upon the
truthfulness of the acknowledgments in this section in deciding to execute and
deliver this Agreement and to become obligated hereunder.

         (c) Representation by Lenders. Each Lender hereby represents that it
will acquire its Note for its own account in the ordinary course of its
commercial lending business; however, the disposition of such Lender's property
shall at all times be and remain within its control and, in particular and
without limitation, such Lender may sell or otherwise transfer its Note, any
participation interest or other interest in its Note, or any of its other rights
and obligations under the Loan Documents subject to compliance with Sections
10.5(b) through (f), inclusive, and applicable Law.

         (d) Joint Acknowledgment. This written 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.

         (e) Annual Rates of Interest. For the purposes of the Interest Act
(Canada), whenever interest payable pursuant to this Agreement is calculated on
the basis of a period other than a calendar year (in this Section 10.1(e), the
"Interest Period"), each rate of interest determined pursuant to such
calculation expressed as an annual rate is equivalent to such rate as so
determined multiplied by the actual number of days in the calendar year in which
the same is to be ascertained and divided by the number of days in the Interest
Period.

         Section 10.2. Survival of Agreements; Cumulative Nature. All of
Restricted Persons' various representations, warranties, covenants and
agreements in the Loan Documents shall survive the execution and delivery of
this Agreement and the other Loan Documents and the performance hereof and
thereof, including the making or granting of the Loans and the delivery of the
Notes and the other Loan Documents, and shall further survive until all of the
Obligations are paid in full to each Lender Party and all of Lender Parties'
obligations to Borrower are terminated. All statements and agreements contained
in any certificate or other instrument

                                       88

<PAGE>

delivered by any Restricted Person to any Lender Party under any Loan Document
shall be deemed representations and warranties by Borrower or agreements and
covenants of Borrower under this Agreement. The representations, warranties,
indemnities, and covenants made by Restricted Persons in the Loan Documents, and
the rights, powers, and privileges granted to Lender Parties in the Loan
Documents, are cumulative, and, except for expressly specified waivers and
consents, no Loan Document shall be construed in the context of another to
diminish, nullify, or otherwise reduce the benefit to any Lender Party of any
such representation, warranty, indemnity, covenant, right, power or privilege.
In particular and without limitation, no exception set out in this Agreement to
any representation, warranty, indemnity, or covenant herein contained shall
apply to any similar representation, warranty, indemnity, or covenant contained
in any other Loan Document, and each such similar representation, warranty,
indemnity, or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various Loan Documents.

         Section 10.3. Notices. All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Administrative Agent may give telephonic notices to the other Lender
Parties), and shall be deemed sufficiently given or furnished if delivered by
personal delivery, by facsimile or other electronic transmission, by delivery
service with proof of delivery, or by registered or certified United States
mail, postage prepaid, to Borrower and Restricted Persons at the address of
Borrower specified on the signature pages hereto and to each Lender Party at its
address specified on the signature pages hereto (unless changed by similar
notice in writing given by the particular Person whose address is to be
changed). Any such notice or communication shall be deemed to have been given
(a) in the case of personal delivery or delivery service, as of the date of
first attempted delivery during normal business hours at the address provided
herein, (b) in the case of facsimile or other electronic transmission, upon
receipt, or (c) in the case of registered or certified United States mail, three
days after deposit in the mail; provided, however, that no Borrowing Notice or
Continuation/Conversion Notice shall become effective until actually received by
Administrative Agent.

         Section 10.4. Payment of Expenses; Indemnity.

                                       89

<PAGE>

         (a) Payment of Expenses. Whether or not the transactions contemplated
by this Agreement are consummated, Borrower will promptly (and in any event,
within 30 days after any invoice or other statement or notice) pay: (i) all
transfer, stamp, mortgage, documentary or other similar taxes, assessments or
charges levied by any governmental or revenue authority in respect of this
Agreement or any of the other Loan Documents or any other document referred to
herein or therein, (ii) all reasonable costs and expenses incurred by or on
behalf of Administrative Agent (including attorneys' fees, consultants' fees and
engineering fees, travel costs and miscellaneous expenses) in connection with
(1) the negotiation, preparation, execution and delivery of the Loan Documents,
and any and all consents, waivers or other documents or instruments relating
thereto, (2) the filing, recording, refiling and re-recording of any Loan
Documents and any other documents or instruments or further assurances required
to be filed or recorded or refiled or re-recorded by the terms of any Loan
Document, (3) the borrowings hereunder and other action reasonably required in
the course of administration hereof, (4) monitoring or confirming (or
preparation or negotiation of any document related to) Borrower's compliance
with any covenants or conditions contained in this Agreement or in any Loan
Document, and (iii) all reasonable costs and expenses incurred by or on behalf
of any Lender Party (including attorneys' fees, consultants' fees and accounting
fees) in connection with the defense or enforcement of any of the Loan Documents
(including this section) or the defense of any Lender Party's exercise of its
rights thereunder. In addition to the foregoing, until all Obligations have been
paid in full, Borrower will also pay or reimburse Administrative Agent for all
reasonable out-of-pocket costs and expenses of Administrative Agent or its
agents or employees in connection with the continuing administration of the
Loans and the related due diligence of Administrative Agent, including travel
and miscellaneous expenses and fees and expenses of Administrative Agent's
outside counsel, reserve engineers and consultants engaged in connection with
the Loan Documents.

         (b) Indemnity. Borrower agrees to indemnify each Lender Party, upon
demand, from and against any and all liabilities, obligations, claims, losses,
damages, penalties, fines, actions, judgments, suits, settlements, costs,
expenses or disbursements (including reasonable fees of attorneys, accountants,
experts and advisors) of any kind or nature whatsoever (in this section
collectively called "liabilities and costs") which to any extent (in whole or in
part) may be imposed on, incurred by, or asserted against such Lender Party
growing out of, resulting from or in any other way associated with any of the
Collateral, the Loan Documents and the transactions and events (including the
enforcement or defense thereof) at any time associated therewith or contemplated
therein whether arising in contract or in tort or otherwise and including any
violation or noncompliance with any Environmental Laws by any Lender Party or
any other Person or any liabilities or duties of any Lender Party or any other
Person with respect to Hazardous Materials found in or released into the
environment).

The foregoing indemnification shall apply whether or not such liabilities and
costs are in any way or to any extent owed, in whole or in part, under any claim
or theory of strict liability or caused, in whole or in part, by any negligent
act or omission of any kind by any Lender Party,

                                       90

<PAGE>

provided only that no Lender Party shall be entitled under this section to
receive indemnification for that portion, if any, of any liabilities and costs
which is proximately caused by its own individual gross negligence or willful
misconduct, as determined in a final judgment. If any Person (including Borrower
or any of its Affiliates) ever alleges such gross negligence or willful
misconduct by any Lender Party, the indemnification provided for in this section
shall nonetheless be paid upon demand, subject to later adjustment or
reimbursement, until such time as a court of competent jurisdiction enters a
final judgment as to the extent and effect of the alleged gross negligence or
willful misconduct. As used in this section the term "Lender Party" shall refer
not only to each Person designated as such in Section 1.1 but also to each
director, officer, agent, attorney, employee, representative and Affiliate of
such Persons.

         Section 10.5. Joint and Several Liability; Parties in Interest;
Assignments; Replacement Notes.

         (a) All Obligations which are incurred by two or more Restricted
Persons shall be their joint and several obligations and liabilities. All
grants, covenants and agreements contained in the Loan Documents shall bind and
inure to the benefit of the parties thereto and their respective successors and
permitted assigns; provided, however, that no Restricted Person may assign or
transfer any of its rights or delegate any of its duties or obligations under
any Loan Document without the prior consent of all Lenders. Neither Borrower nor
any Affiliates of Borrower shall directly or indirectly purchase or otherwise
retire any Obligations owed to any Lender nor will any Lender accept any offer
to do so, unless each Lender shall have received substantially the same offer
with respect to the same Percentage Share of the Obligations owed to it. If
Borrower or any Affiliate of Borrower at any time purchases some but less than
all of the Obligations owed to all Lender Parties, such purchaser shall not be
entitled to any rights of any Lender under the Loan Documents unless and until
Borrower or its Affiliates have purchased all of the Obligations.

         (b) No Lender shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person unless the agreement between such Lender and such participant at all
times provides: (i) that such participation exists only as a result of the
agreement between such participant and such Lender and that such transfer does
not give such participant any right to vote as a Lender or any other direct
claims or rights against any Person other than such Lender, (ii) that such
participant is not entitled to payment from any Restricted Person under Sections
3.2 through 3.6 of amounts in excess of those payable to such Lender under such
sections (determined without regard to the sale of such participation), and
(iii) unless such participant is an Affiliate of such Lender, that such
participant shall not be entitled to require such Lender to take any action
under any Loan Document or to obtain the consent of such participant prior to
taking any action under any Loan Document, except for actions which would
require the consent of all Lenders under subsection (a) of Section 10.1. No
Lender selling such a participation shall, as between the other parties hereto
and such Lender, be relieved of any of its obligations hereunder as a result of
the sale of such participation. Each Lender which sells any such participation
to any Person (other than an Affiliate of such Lender) shall give prompt notice
thereof to Administrative Agent and Borrower; provided, however, that no
liability shall arise if any Lender fails to give such notice to Borrower.

         (c) Except for sales of participations under the immediately preceding
subsection, no Lender shall make any assignment or transfer of any kind of its
commitments or any of its rights

                                       91

<PAGE>

under its Loans or under the Loan Documents, except for assignments to an
Eligible Transferee, or, subject to the provisions of subsection (g) below, to
an Affiliate and then only if such assignment is made in accordance with the
following requirements:

                  (i)   Each such assignment shall apply to all Obligations
         owing to the assignor Lender hereunder and to the unused portion of the
         assignor Lender's commitments, so that after such assignment is made
         the assignor Lender shall have a fixed (and not a varying) Percentage
         Share in its Loans and Note and be committed to make that Percentage
         Share of all future Loans, the assignee shall have a fixed Percentage
         Share in such Loans and Note and be committed to make that Percentage
         Share of all future Loans, and the Percentage Share of the Maximum
         Facility Amount of each of the assignor and assignee shall equal or
         exceed $5,000,000.

                  (ii)  The parties to each such assignment shall execute and
         deliver to Administrative Agent, for its acceptance and recording in
         the "Register" (as defined below in this section), an Assignment and
         Acceptance in the form of Exhibit J, appropriately completed, together
         with the Note subject to such assignment and a processing fee payable
         by such assignor Lender (and not at Borrower's expense) to
         Administrative Agent of $3,500. Upon such execution, delivery, and
         payment and upon the satisfaction of the conditions set out in such
         Assignment and Acceptance, then (i) Borrower shall issue new Notes to
         such assignor and assignee upon return of the old Notes to Borrower,
         and (ii) as of the "Settlement Date" specified in such Assignment and
         Acceptance the assignee thereunder shall be a party hereto and a Lender
         hereunder and Administrative Agent shall thereupon deliver to Borrower
         and each Lender a revised Schedule 1 hereto showing the revised
         Percentage Shares of such assignor Lender and such assignee Lender and
         the Percentage Shares of all other Lenders.

                  (iii) Each assignee Lender which is not a United States person
         (as such term is defined in Section 7701(a)(30) of the Code) for
         Federal income tax purposes, shall (to the extent it has not already
         done so) provide Administrative Agent and Borrower with the "Prescribed
         Forms" referred to in Section 3.7(d).

         (d) Any Lender may at any time pledge all or any portion of its Loan
and Note (and related rights under the Loan Documents including any portion of
its Note) to any of the twelve (12) Federal Reserve Banks organized under
Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or
enforcement thereof shall release any such Lender from its obligations under any
of the Loan Documents; provided that all related costs, fees and expenses in
connection with any such pledge shall be for the sole account of such Lender.

         (e) By executing and delivering an Assignment and Acceptance, each
assignee Lender thereunder will be confirming to and agreeing with Borrower,
Administrative Agent and each other Lender Party that such assignee understands
and agrees to the terms hereof, including Article IX hereof.

         (f) Administrative Agent shall maintain a copy of each Assignment and
Acceptance and a register for the recordation of the names and addresses of
Lenders and the Percentage Shares of,

                                       92

<PAGE>

and principal amount of the Loans owing to, each Lender from time to time (in
this section called the "Register"). The entries in the Register shall be
conclusive, in the absence of manifest error, and Borrower and each Lender Party
may treat each Person whose name is recorded in the Register as a Lender Party
hereunder for all purposes. The Register shall be available for inspection by
Borrower or any Lender Party at any reasonable time and from time to time upon
reasonable prior notice.

         (g) Any Lender may assign or transfer its commitment or its rights
under its Loans or under the Loan Documents to (i) any Affiliate that is
wholly-owned direct or indirect subsidiary of such Lender or of any Person that
wholly owns, directly or indirectly, such Lender, or (ii) if such Lender is a
fund that invests in bank loans, any other fund that invests in bank loans and
is advised or managed by (A) the same investment advisor as any Lender or (B)
any Affiliate of such investment advisor that is a wholly-owned direct or
indirect subsidiary of any Person that wholly owns, directly or indirectly, such
investment advisor, subject to the following additional conditions:

         (x) any right of such Lender assignor and such assignee to vote as a
         Lender, or any other direct claims or rights against any other Persons,
         shall be uniformly exercised or pursued in the manner that such Lender
         assignor would have so exercised such vote, claim or right if it had
         not made such assignment or transfer;

         (y) such assignee shall not be entitled to payment from any Restricted
         Person under Sections 3.2 through 3.7 of amounts in excess of those
         payable to such Lender assignor under such sections (determined without
         regard to such assignment or transfer); and

         (z) if such Lender assignor assigns or transfers to such assignee any
         of such Lender's commitment, such assignee may become primarily liable
         for such commitment, but such assignment or transfer shall not relieve
         or release such Lender from such commitment.

         (h) Upon receipt of an affidavit reasonably satisfactory to Borrower of
an officer of any Lender as to the loss, theft, destruction or mutilation of its
Note or any Security Document which is not of public record, and, in the case of
any such loss, theft, destruction or mutilation, upon cancellation of such Note
or such Security Document, Borrower will execute and deliver, in lieu thereof, a
replacement Note in the same principal amount thereof and otherwise of like
tenor (or each Restricted Person a party to any such Security Document will
execute and deliver a replacement Security Document of like tenor).

         Section 10.6. Confidentiality. Each Lender Party agrees (on behalf of
itself and each of its Affiliates, and each of its and their directors,
officers, agents, attorneys, employees, and representatives) that it (and each
of them) will take all reasonable steps to keep confidential any non-public
information supplied to it by or at the direction of any Restricted Person so
identified when delivered, provided, however, that this restriction shall not
apply to (a) information which has at the time in question entered the public
domain, (b) information which is required to be disclosed by Law (whether valid
or invalid) of any Tribunal, (c) any disclosure to any Lender Party's
Affiliates, auditors, attorneys, or agents, (d) any disclosure to any other
Lender Party or to any purchaser or prospective purchaser of participations or
other interests in any Loan or Loan

                                       93

Document (provided each such Person first agrees to hold such information in
confidence on the terms provided in this section), or (e) any disclosure in the
course of enforcing its rights and remedies during the existence of an Event of
Default.

         Section 10.7. Governing Law; Submission to Process. EXCEPT TO THE
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN
DOCUMENT, THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE
UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK AND THE LAWS
OF THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF
LAW. BORROWER HEREBY AGREES THAT ANY LEGAL ACTION OR PROCEEDING AGAINST BORROWER
WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY OF THE LOAN DOCUMENTS MAY BE
BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES OF
AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK AS LENDER PARTIES MAY ELECT, AND,
BY EXECUTION AND DELIVERY HEREOF, BORROWER ACCEPTS AND CONSENTS FOR ITSELF AND
IN RESPECT TO ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE NON-EXCLUSIVE
JURISDICTION OF THE AFORESAID COURTS. BORROWER AGREES THAT SECTIONS 5-1401 AND
5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK SHALL APPLY TO
THE LOAN DOCUMENTS AND WAIVES ANY RIGHT TO STAY OR TO DISMISS ANY ACTION OR
PROCEEDING BROUGHT BEFORE SAID COURTS ON THE BASIS OF FORUM NON CONVENIENS. IN
FURTHERANCE OF THE FOREGOING, BORROWER HEREBY IRREVOCABLY DESIGNATES AND
APPOINTS CORPORATION SERVICE COMPANY, 80 STATE STREET, ALBANY, NEW YORK 12207,
AS AGENT OF BORROWER TO RECEIVE SERVICE OF ALL PROCESS BROUGHT AGAINST BORROWER
WITH RESPECT TO ANY SUCH PROCEEDING IN ANY SUCH COURT IN NEW YORK, SUCH SERVICE
BEING HEREBY ACKNOWLEDGED BY BORROWER TO BE EFFECTIVE AND BINDING SERVICE IN
EVERY RESPECT. COPIES OF ANY SUCH PROCESS SO SERVED SHALL ALSO, IF PERMITTED BY
LAW, BE SENT BY REGISTERED MAIL TO BORROWER AT ITS ADDRESS SET FORTH BELOW, BUT
THE FAILURE OF BORROWER TO RECEIVE SUCH COPIES SHALL NOT AFFECT IN ANY WAY THE
SERVICE OF SUCH PROCESS AS AFORESAID. BORROWER SHALL FURNISH TO LENDER PARTIES A
CONSENT OF CORPORATION SERVICE COMPANY AGREEING TO ACT HEREUNDER PRIOR TO THE
EFFECTIVE DATE OF THIS AGREEMENT. NOTHING HEREIN SHALL AFFECT THE RIGHT OF
LENDER PARTIES TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL
LIMIT THE RIGHT OF LENDER PARTIES TO BRING PROCEEDINGS AGAINST BORROWER IN THE
COURTS OF ANY OTHER JURISDICTION. IF FOR ANY REASON CORPORATION SERVICE COMPANY
SHALL RESIGN OR OTHERWISE CEASE TO ACT AS BORROWER'S AGENT, BORROWER HEREBY
IRREVOCABLY AGREES TO

                                       94

<PAGE>

(A) IMMEDIATELY DESIGNATE AND APPOINT A NEW AGENT ACCEPTABLE TO ADMINISTRATIVE
AGENT TO SERVE IN SUCH CAPACITY AND, IN SUCH EVENT, SUCH NEW AGENT SHALL BE
DEEMED TO BE SUBSTITUTED FOR CORPORATION SERVICE COMPANY FOR ALL PURPOSES HEREOF
AND (B) PROMPTLY DELIVER TO AGENT THE WRITTEN CONSENT (IN FORM AND SUBSTANCE
SATISFACTORY TO ADMINISTRATIVE AGENT) OF SUCH NEW AGENT AGREEING TO SERVE IN
SUCH CAPACITY.

         Section 10.8. Waiver of Judgment Interest Act (Alberta). To the extent
permitted by Law, the provisions of the Judgment Interest Act (Alberta) shall
not apply to LC Obligations with respect to Canadian Letters of Credit and the
other Loan Documents and are hereby expressly waived by Borrower.

         Section 10.9. Deemed Reinvestment Not Applicable. For the purposes of
the Interest Act (Canada), the principle of deemed reinvestment of interest
shall not apply to any interest calculation under the Loan Documents, and the
rates of interest stipulated in this Agreement are intended to be nominal rates
and not effective rates or yields.

         Section 10.10. Limitation on Interest. Lender Parties, Restricted
Persons and any other parties to the Loan Documents intend to contract in strict
compliance with applicable usury Law from time to time in effect. In furtherance
thereof such Persons stipulate and agree that none of the terms and provisions
contained in the Loan Documents shall ever be construed to create a contract to
pay, for the use, forbearance or detention of money, interest in excess of the
maximum amount of interest permitted to be contracted for, charged, or received
by applicable Law from time to time in effect. Neither any Restricted Person nor
any present or future guarantors, endorsers, or other Persons hereafter becoming
liable for payment of any Obligation shall ever be liable for unearned interest
thereon or shall ever be required to pay interest thereon in excess of the
maximum amount that may be lawfully contracted for, charged, or received under
applicable Law from time to time in effect, and the provisions of this section
shall control over all other provisions of the Loan Documents which may be in
conflict or apparent conflict herewith. Lender Parties expressly disavow any
intention to contract for, charge, or receive excessive unearned interest or
finance charges in the event the maturity of any Obligation is accelerated. If
(a) the maturity of any Obligation is accelerated for any reason, (b) any
Obligation is prepaid and as a result any amounts held to constitute interest
are determined to be in excess of the legal maximum, or (c) any Lender or any
other holder of any or all of the Obligations shall otherwise collect moneys
which are determined to constitute interest which would otherwise increase the
interest on any or all of the Obligations to an amount in excess of that
permitted to be contracted for, charged or received by applicable Law then in
effect, then all sums determined to constitute interest in excess of such legal
limit shall, without penalty, be promptly applied to reduce the then outstanding
principal of the related Obligations or, at such Lender's or holder's option,
promptly returned to Borrower or other payor thereof upon such determination. In
determining whether or not the interest paid or payable, under any specific
circumstance, exceeds the maximum amount permitted under applicable Law, Lender
Parties and Restricted Persons (and any other payors thereof) shall to the
greatest extent permitted under applicable Law, (i) characterize any
non-principal payment as an expense, fee or premium rather than as interest,

                                       95

<PAGE>

(ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize,
prorate, allocate, and spread the total amount of interest throughout the entire
contemplated term of the instruments evidencing the Obligations in accordance
with the amounts outstanding from time to time thereunder and the maximum legal
rate of interest from time to time in effect under applicable Law in order to
lawfully charge the maximum amount of interest permitted under applicable Law.
In the event applicable Law provides for an interest ceiling under Chapter 303
of the Texas Finance Code (the "Texas Finance Code") as amended, to the extent
that the Texas Finance Code is mandatorily applicable to any Lender, for that
day, the ceiling shall be the "weekly ceiling" as defined in the Texas Finance
Code, provided that if any applicable Law permits greater interest, the Law
permitting the greatest interest shall apply. In no event shall Chapter 346 of
the Texas Finance Code apply to this Agreement or any other Loan Document, or
any transactions or loan arrangement provided or contemplated hereby or thereby.

         Section 10.11. Termination; Limited Survival. In its sole and absolute
discretion Borrower may at any time that no Obligations are owing or outstanding
elect in a written notice delivered to Administrative Agent to terminate this
Agreement. Upon receipt by Administrative Agent of such a notice, if no
Obligations are then owing or outstanding this Agreement and all other Loan
Documents shall thereupon be terminated and the parties thereto released from
all prospective obligations thereunder. Notwithstanding the foregoing or
anything herein to the contrary, any waivers or admissions made by any
Restricted Person in any Loan Document, any Obligations under Sections 3.2
through 3.6, and any obligations which any Person may have to indemnify or
compensate any Lender Party shall survive any termination of this Agreement or
any other Loan Document. At the request and expense of Borrower, Administrative
Agent shall prepare and execute all necessary instruments to reflect and effect
such termination of the Loan Documents. Administrative Agent is hereby
authorized to execute all such instruments on behalf of all Lenders, without the
joinder of or further action by any Lender.

         Section 10.12. Severability. If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

         Section 10.13. Counterparts. This Agreement may be separately executed
in any number of counterparts and by different parties hereto in separate
counterparts, each of which when so executed shall be deemed to constitute one
and the same Agreement.

         Section 10.14. Waiver of Jury Trial, Punitive Damages, etc. Restricted
Persons and Lender Parties mutually hereby knowingly, voluntarily, and
intentionally waive the right to a trial by jury in respect of any claim based
hereon, arising out of, under or in connection with, this Agreement or any other
Loan Documents contemplated to be executed in connection herewith or any course
of conduct, course of dealings, statements (whether verbal or written) or
actions of any party. This waiver constitutes a material inducement for Lenders
to enter into this Agreement and the other Loan Documents and make

                                       96

<PAGE>

the Loans. Borrower and each Lender Party hereby further (a) irrevocably waives,
to the maximum extent not prohibited by Law, any right it may have to claim or
recover in any such litigation any "Special Damages," as defined below, (b)
certifies that no party hereto nor any representative or agent or counsel for
any party hereto has represented, expressly or otherwise, or implied that such
party would not, in the event of litigation, seek to enforce the foregoing
waivers, and (c) acknowledges that it has been induced to enter into this
Agreement, the other Loan Documents and the transactions contemplated hereby and
thereby by, among other things, the mutual waivers and certifications contained
in this section. As used in this section, "Special Damages" includes all
special, consequential, exemplary, or punitive damages (regardless of how
named), but does not include any payments or funds which any party hereto has
expressly promised to pay or deliver to any other party hereto.

         Section 10.15. Amendment and Restatement. Upon satisfaction with each
of the conditions set forth in Section 4.3 (except any condition the performance
of which has been waived as a condition to the initial Loan or initial issuance
of a Letter of Credit pursuant to this Agreement), this Agreement shall be
deemed to amend and restate in its entirety the Existing Agreement, at which
time (the "Effective Time") each Lender and each Restricted Person hereby agrees
that (i) the Percentage Share of each Lender shall be as set forth in the
definition to this Agreement, (ii) the loans outstanding under the Existing
Agreement and all accrued and unpaid interest thereon, all letters of credit
issued and outstanding under the Existing Agreement and reimbursement
obligations with respect thereto, and all accrued and unpaid fees and expenses
under the Existing Agreement (the "Outstanding Obligations") shall be deemed to
be outstanding under and governed by this Agreement, and (iii) any "Lender"
under the Existing Agreement that is not a signatory hereto as a Lender under
this Agreement, shall continue to be a Lender, subject to the rights, remedies
and obligations of a "Lender" in this Agreement, and in no event shall be deemed
to have waived or released any of its rights or remedies, nor released from its
obligations under the Existing Agreement, all of which such rights, remedies and
obligations shall continue pursuant to, and as may be amended or restated
pursuant to, the terms hereof; provided, until such time as all "Lenders" under
the Existing Agreement execute and deliver this Agreement, any term or provision
of the Existing Agreement stated herein to be amended hereby that would, under
the terms of the Existing Agreement, require each "Lender" under the Existing
Agreement to consent to such amendment shall not be so amended, and such term or
provision as set forth in the Existing Agreement shall be deemed to be
incorporated herein verbatim and with respect to such term or provisions, shall
be the operative provision of this Agreement, until such time as all "Lenders"
under the Existing Agreement shall have executed and delivered this Agreement,
at which time such amended terms or provisions as set forth herein shall
thereafter govern; provided, further, however, for the avoidance of doubt, all
other terms and provisions of this Agreement shall be effective upon
satisfaction of the conditions set forth in Section 4.3.
