                      THE COMMITMENTS AND CREDIT EXTENSIONS

     2.01  Revolving Loans and Term Loan.

     (a)   Revolving Loans. Subject to the terms and conditions set forth
herein, each Lender severally agrees to make loans (each such loan, a "Revolving
Loan") to the Borrower in Dollars from time to time on any Business Day during
the Availability Period in an aggregate amount not to exceed at any time
outstanding the amount of such Lender's Revolving Commitment; provided, however,
that after giving effect to any Borrowing of Revolving Loans, (i) the Total
Revolving Outstandings shall not exceed the Aggregate Revolving Commitments and
(ii) the aggregate Outstanding Amount of the Revolving Loans of any Lender plus
such Lender's Pro Rata Share of the Outstanding Amount of all L/C Obligations
shall not exceed such Lender's Revolving Commitment. Within the limits of each
Lender's Revolving Commitment, and subject to the other terms and conditions
hereof, the Borrower may borrow under this Section 2.01, prepay under Section
2.05 and reborrow under this Section 2.01. Revolving Loans may be Base Rate
Loans or Eurodollar Rate Loans, as further provided herein, provided, however,
that all Borrowings of Revolving Loans made on the Closing Date shall be made as
Base Rate Loans.

     (b)   Term Loan. Subject to the terms and conditions set forth herein, each
Lender severally agrees to make its portion of a term loan (the "Term Loan") to
the Borrower on the Closing Date in an amount not to exceed such Lender's Term
Loan Commitment. Amounts repaid on the Term Loan may not be reborrowed. The Term
Loan may consist of Base Rate Loans or Eurodollar Rate Loans, as further
provided herein.

     2.02  Borrowings, Conversions and Continuations of Loans.

     (a)   Each Borrowing, each conversion of Loans from one Type to the other
and each continuation of Eurodollar Rate Loans shall be made upon the Borrower's
irrevocable notice to the Administrative Agent, which may be given by telephone.
Each such notice must be received by the Administrative Agent not later than
11:00 a.m. (i) three Business Days prior to the requested date of any Borrowing
of, conversion to or continuation of Eurodollar Rate Loans or of any conversion
of Eurodollar Rate Loans to Base Rate Loans, and (ii) on the requested date of
any Borrowing of Base Rate Loans. Each telephonic notice by the Borrower
pursuant to this Section 2.02(a) must be confirmed promptly by delivery to the
Administrative Agent of a written Loan Notice, appropriately completed and
signed by a

<PAGE>

Responsible Officer of the Borrower. Each Borrowing of, conversion to or
continuation of Eurodollar Rate Loans shall be in a principal amount of
$1,000,000 or a whole multiple of $100,000 in excess thereof. Except as provided
in Section 2.03(c), each Borrowing of or conversion to Base Rate Loans shall be
in a principal amount of $500,000 or a whole multiple of $100,000 in excess
thereof. Each Loan Notice (whether telephonic or written) shall specify (i)
whether the Borrower is requesting a Borrowing, a conversion of Loans from one
Type to the other or a continuation of Eurodollar Rate Loans, (ii) the requested
date of the Borrowing, conversion or continuation, as the case may be (which
shall be a Business Day), (iii) the principal amount of Loans to be borrowed,
converted or continued, (iv) the Type of Loans to be borrowed or to which
existing Loans are to be converted, and (v) if applicable, the duration of the
Interest Period with respect thereto. If the Borrower fails to specify a Type of
Loan in a Loan Notice or if the Borrower fails to give a timely notice
requesting a conversion or continuation, then the applicable Loans shall be made
as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate
Loans shall be effective as of the last day of the Interest Period then in
effect with respect to the applicable Eurodollar Rate Loans. If the Borrower
requests a Borrowing of, conversion to or continuation of Eurodollar Rate Loans
in any such Loan Notice, but fails to specify an Interest Period, it will be
deemed to have specified an Interest Period of one month.

     (b)   Following receipt of a Loan Notice, the Administrative Agent shall
promptly notify each Lender of the amount of its Pro Rata Share of the
applicable Loans, and, if no timely notice of a conversion or continuation is
provided by the Borrower, the Administrative Agent shall notify each Lender of
the details of any automatic conversion to Base Rate Loans described in the
preceding subsection. In the case of a Borrowing, each Lender shall make the
amount of its Loan available to the Administrative Agent in immediately
available funds at the Administrative Agent's Office not later than 1:00 p.m. on
the Business Day specified in the applicable Loan Notice. Upon satisfaction of
the applicable conditions set forth in Section 5.02 (and, if such Borrowing is
the initial Credit Extension, Section 5.01), the Administrative Agent shall make
all funds so received available to the Borrower in like funds as received by the
Administrative Agent either by (i) crediting the account of the Borrower on the
books of Wells Fargo with the amount of such funds or (ii) wire transfer of such
funds, in each case in accordance with instructions provided to (and reasonably
acceptable to) the Administrative Agent by the Borrower; provided, however, that
if, on the date of a Borrowing of Revolving Loans, there are L/C Borrowings
outstanding, then the proceeds of such Borrowing shall be applied, first, to the
payment in full of any such L/C Borrowings, and, second, to the Borrower as
provided above.

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

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

     (e)   After giving effect to all Borrowings, all conversions of Loans from
one Type to the other and all continuations of Loans as the same Type, there
shall not be more than (i) five Interest Periods in effect with respect to
Revolving Loans and (ii) five Interest Periods in effect with respect to the
Term Loan.

     2.03  Letters of Credit.

<PAGE>

     (a)   The Letter of Credit Commitment.

           (i)   Subject to the terms and conditions set forth herein, (A) the
     L/C Issuer agrees, in reliance upon the agreements of the other Lenders set
     forth in this Section 2.03, (1) from time to time on any Business Day
     during the period from the Closing Date until the Letter of Credit
     Expiration Date, to issue Letters of Credit in Dollars and otherwise in
     form and substance satisfactory to the L/C Issuer for the account of the
     Borrower, and to amend or renew such Letters of Credit previously issued by
     it, in accordance with subsection (b) below, and (2) to honor drafts drawn
     under the Letters of Credit; and (B) the Lenders severally agree to
     participate in Letters of Credit issued for the account of the Borrower and
     any drawings thereunder; provided that the L/C Issuer shall not be
     obligated to make any L/C Credit Extension with respect to any Letter of
     Credit, and no Lender shall be obligated to participate in any Letter of
     Credit if as of the date of such L/C Credit Extension, (1) the Total
     Revolving Outstandings would exceed the Aggregate Revolving Commitments,
     (2) the aggregate Outstanding Amount of the Revolving Loans of any Lender
     plus such Lender's Pro Rata Share of the Outstanding Amount of all L/C
     Obligations would exceed such Lender's Revolving Commitment or (3) the
     Outstanding Amount of the L/C Obligations would exceed the Letter of Credit
     Sublimit. Each request by the Borrower for the issuance or amendment of a
     Letter of Credit shall be deemed to be a representation by the Borrower
     that the L/C Credit Extension so requested complies with the conditions set
     forth in the proviso to the preceding sentence. Within the foregoing
     limits, and subject to the terms and conditions hereof, the Borrower's
     ability to obtain Letters of Credit shall be fully revolving, and
     accordingly the Borrower may, during the foregoing period, obtain Letters
     of Credit to replace Letters of Credit that have expired or that have been
     drawn upon and reimbursed.

           (ii)  The L/C Issuer shall be under no obligation to issue any Letter
     of Credit if:

                 (A)  any order, judgment or decree of any Governmental
           Authority or arbitrator shall by its terms purport to enjoin or
           restrain the L/C Issuer from issuing such Letter of Credit, or any
           Law applicable to the L/C Issuer or any request or directive (whether
           or not having the force of law) from any Governmental Authority with
           jurisdiction over the L/C Issuer shall prohibit, or request that the
           L/C Issuer refrain from, the issuance of letters of credit generally
           or such Letter of Credit in particular or shall impose upon the L/C
           Issuer with respect to such Letter of Credit any restriction, reserve
           or capital requirement (for which the L/C Issuer is not otherwise
           compensated hereunder) not in effect on the Closing Date, or shall
           impose upon the L/C Issuer any unreimbursed loss, cost or expense
           which was not applicable on the Closing Date and which the L/C Issuer
           in good faith deems material to it;

                 (B)  subject to Section 2.03(b)(iii), the expiry date of such
           requested Letter of Credit would occur more than twelve months after
           the date of issuance or last renewal, unless the Required Lenders
           have approved such expiry date;

                 (C)  the expiry date of such requested Letter of Credit would
           occur after the Letter of Credit Expiration Date, unless all the
           Lenders have approved such expiry date;

                 (D)  the issuance of such Letter of Credit would violate any
           Laws or any policy of the L/C Issuer; or

                 (E)  such Letter of Credit is to be denominated in a currency
           other than Dollars.

<PAGE>

           (iii) The L/C Issuer shall not amend any Letter of Credit if the L/C
     Issuer would not be permitted at such time to issue such Letter of Credit
     in its amended form under the terms hereof.

           (iv)  The L/C Issuer shall be under no obligation to amend any Letter
     of Credit if (A) the L/C Issuer would have no obligation at such time to
     issue such Letter of Credit in its amended form under the terms hereof, or
     (B) the beneficiary of such Letter of Credit does not accept the proposed
     amendment to such Letter of Credit.

           (v)   The L/C Issuer shall be under no obligation to issue or amend
     any Letter of Credit if the L/C Issuer has received written notice from any
     Lender, the Administrative Agent or any Loan Party, on or prior to the
     Business Day prior to the requested date of issuance or amendment of such
     Letter of Credit, that one or more applicable conditions contained in
     Article V shall not then be satisfied.

     (b)   Procedures for Issuance and Amendment of Letters of Credit;
Auto-Renewal Letters of Credit.

           (i)   Each Letter of Credit shall be issued or amended, as the case
     may be, upon the request of the Borrower delivered to the L/C Issuer (with
     a copy to the Administrative Agent) in the form of a Letter of Credit
     Application, appropriately completed and signed by a Responsible Officer of
     the Borrower. Such Letter of Credit Application must be received by the L/C
     Issuer and the Administrative Agent not later than 11:00 a.m. at least two
     Business Days (or such later date and time as the L/C Issuer may agree in a
     particular instance in its sole discretion) prior to the proposed issuance
     date or date of amendment, as the case may be. In the case of a request for
     an initial issuance of a Letter of Credit, such Letter of Credit
     Application shall specify in form and detail satisfactory to the L/C
     Issuer: (A) the proposed issuance date of the requested Letter of Credit
     (which shall be a Business Day); (B) the amount thereof; (C) the expiry
     date thereof; (D) the name and address of the beneficiary thereof; (E) the
     documents to be presented by such beneficiary in case of any drawing
     thereunder; (F) the full text of any certificate to be presented by such
     beneficiary in case of any drawing thereunder; and (G) such other matters
     as the L/C Issuer may require. In the case of a request for an amendment of
     any outstanding Letter of Credit, such Letter of Credit Application shall
     specify in form and detail satisfactory to the L/C Issuer (A) the Letter of
     Credit to be amended; (B) the proposed date of amendment thereof (which
     shall be a Business Day); (C) the nature of the proposed amendment; and (D)
     such other matters as the L/C Issuer may require. Additionally, the
     Borrower shall furnish to the L/C Issuer and the Administrative Agent such
     other documents and information pertaining to such requested Letter of
     Credit issuance or amendment as the L/C Issuer or the Administrative Agent
     may require.

           (ii)  Promptly after receipt of any Letter of Credit Application, the
     L/C Issuer will confirm with the Administrative Agent (by telephone or in
     writing) that the Administrative Agent has received a copy of such Letter
     of Credit Application from the Borrower and, if not, the L/C Issuer will
     provide the Administrative Agent with a copy thereof. Upon receipt by the
     L/C Issuer of confirmation from the Administrative Agent that the requested
     issuance or amendment is permitted in accordance with the terms hereof,
     then, subject to the terms and conditions hereof, the L/C Issuer shall, on
     the requested date, issue a Letter of Credit for the account of the
     Borrower or enter into the applicable amendment, as the case may be, in
     each case in accordance with the L/C Issuer's usual and customary business
     practices. Immediately upon the issuance of each Letter of Credit, each
     Lender shall be deemed to, and hereby irrevocably and

<PAGE>

     unconditionally agrees to, purchase from the L/C Issuer a risk
     participation in such Letter of Credit in an amount equal to the product of
     such Lender's Pro Rata Share times the amount of such Letter of Credit.

           (iii) If the Borrower so requests in any applicable Letter of Credit
     Application, the L/C Issuer may, in its sole and absolute discretion, agree
     to issue a Letter of Credit that has automatic renewal provisions (each, an
     "Auto-Renewal Letter of Credit"); provided that any such Auto-Renewal
     Letter of Credit must permit the L/C Issuer to prevent any such renewal at
     least once in each twelve-month period (commencing with the date of
     issuance of such Letter of Credit) by giving prior notice to the
     beneficiary thereof not later than a day (the "Nonrenewal Notice Date") in
     each such twelve-month period to be agreed upon at the time such Letter of
     Credit is issued. Unless otherwise directed by the L/C Issuer, the Borrower
     shall not be required to make a specific request to the L/C Issuer for any
     such renewal. Once an Auto-Renewal Letter of Credit has been issued, the
     Lenders shall be deemed to have authorized (but may not require) the L/C
     Issuer to permit the renewal of such Letter of Credit at any time to an
     expiry date not later than the Letter of Credit Expiration Date; provided,
     however, that the L/C Issuer shall not permit any such renewal if (A) the
     L/C Issuer has determined that it would have no obligation at such time to
     issue such Letter of Credit in its renewed form under the terms hereof (by
     reason of the provisions of Section 2.03(a)(ii) or otherwise), or (B) it
     has received notice (which may be by telephone or in writing) on or before
     the day that is two Business Days before the Nonrenewal Notice Date from
     the Administrative Agent, any Lender or the Borrower that one or more of
     the applicable conditions specified in Section 5.02 is not then satisfied.

           (iv)  Promptly after its delivery of any Letter of Credit or any
     amendment to a Letter of Credit to an advising bank with respect thereto or
     to the beneficiary thereof, the L/C Issuer will also deliver to the
     Borrower and the Administrative Agent a true and complete copy of such
     Letter of Credit or amendment.

     (c)   Drawings and Reimbursements; Funding of Participations.

           (i)   Upon receipt from the beneficiary of any Letter of Credit of
     any notice of drawing under such Letter of Credit, the L/C Issuer shall
     notify the Borrower and the Administrative Agent thereof. Not later than
     11:00 a.m. on the date of any payment by the L/C Issuer under a Letter of
     Credit (each such date, an "Honor Date") (or, if the time of such payment
     by the L/C Issuer is after 11:00 a.m., promptly after the time of such
     payment and, in any event, no later than 3:00 p.m. on the Honor Date), the
     Borrower shall reimburse the L/C Issuer through the Administrative Agent in
     an amount equal to the amount of such drawing. If the Borrower fails to so
     reimburse the L/C Issuer by such time, the Administrative Agent shall
     promptly notify each Lender of the Honor Date, the amount of the
     unreimbursed drawing (the "Unreimbursed Amount") and the amount of such
     Lender's Pro Rata Share thereof. In such event, the Borrower shall be
     deemed to have requested a Borrowing of Base Rate Revolving Loans to be
     disbursed on the Honor Date in an amount equal to the Unreimbursed Amount,
     without regard to the minimum and multiples specified in Section 2.02 for
     the principal amount of Base Rate Loans, but subject to the amount of the
     unutilized portion of the Aggregate Revolving Commitments and the
     conditions set forth in Section 5.02 (other than the delivery of a Loan
     Notice). Any notice given by the L/C Issuer or the Administrative Agent
     pursuant to this Section 2.03(c)(i) may be given by telephone if
     immediately confirmed in writing; provided that the lack of such an
     immediate confirmation shall not affect the conclusiveness or binding
     effect of such notice.

           (ii)  Each Lender (including the Lender acting as L/C Issuer) shall
     upon any notice pursuant to Section 2.03(c)(i) make funds available to the
     Administrative Agent for the account

<PAGE>

     of the L/C Issuer at the Administrative Agent's Office in an amount equal
     to its Pro Rata Share of the Unreimbursed Amount not later than 1:00 p.m.
     on the Business Day specified in such notice by the Administrative Agent,
     whereupon, subject to the provisions of Section 2.03(c)(iii), each Lender
     that so makes funds available shall be deemed to have made a Base Rate
     Revolving Loan to the Borrower in such amount. The Administrative Agent
     shall remit the funds so received to the L/C Issuer.

           (iii) With respect to any Unreimbursed Amount that is not fully
     refinanced by a Borrowing of Base Rate Revolving Loans because the
     conditions set forth in Section 5.02 cannot be satisfied or for any other
     reason, the Borrower shall be deemed to have incurred from the L/C Issuer
     an L/C Borrowing in the amount of the Unreimbursed Amount that is not so
     refinanced, which L/C Borrowing shall be due and payable on demand
     (together with interest) and shall bear interest at the Default Rate. In
     such event, each Lender's payment to the Administrative Agent for the
     account of the L/C Issuer pursuant to Section 2.03(c)(ii) shall be deemed
     payment in respect of its participation in such L/C Borrowing and shall
     constitute an L/C Advance from such Lender in satisfaction of its
     participation obligation under this Section 2.03.

           (iv)  Until each Lender funds its Revolving Loan or L/C Advance
     pursuant to this Section 2.03(c) to reimburse the L/C Issuer for any amount
     drawn under any Letter of Credit, interest in respect of such Lender's Pro
     Rata Share of such amount shall be solely for the account of the L/C
     Issuer.

           (v)   Each Lender's obligation to make Revolving Loans or L/C
     Advances to reimburse the L/C Issuer for amounts drawn under Letters of
     Credit, as contemplated by this Section 2.03(c), shall be absolute and
     unconditional and shall not be affected by any circumstance, including (A)
     any set-off, counterclaim, recoupment, defense or other right which such
     Lender may have against the L/C Issuer, the Borrower or any other Person
     for any reason whatsoever; (B) the occurrence or continuance of a Default,
     or (C) any other occurrence, event or condition, whether or not similar to
     any of the foregoing; provided, however, that each Lender's obligation to
     make Revolving Loans pursuant to this Section 2.03(c) is subject to the
     conditions set forth in Section 5.02 (other than delivery by the Borrower
     of a Loan Notice). No such making of an L/C Advance shall relieve or
     otherwise impair the obligation of the Borrower to reimburse the L/C Issuer
     for the amount of any payment made by the L/C Issuer under any Letter of
     Credit, together with interest as provided herein.

           (vi)  If any Lender fails to make available to the Administrative
     Agent for the account of the L/C Issuer any amount required to be paid by
     such Lender pursuant to the foregoing provisions of this Section 2.03(c) by
     the time specified in Section 2.03(c)(ii), the L/C Issuer shall be entitled
     to recover from such Lender (acting through the Administrative Agent), on
     demand, such amount with interest thereon for the period from the date such
     payment is required to the date on which such payment is immediately
     available to the L/C Issuer at a rate per annum equal to the Federal Funds
     Rate from time to time in effect. A certificate of the L/C Issuer submitted
     to any Lender (through the Administrative Agent) with respect to any
     amounts owing under this clause (vi) shall be conclusive absent manifest
     error.

     (d)   Repayment of Participations.

           (i)   At any time after the L/C Issuer has made a payment under any
     Letter of Credit and has received from any Lender such Lender's L/C Advance
     in respect of such payment in accordance with Section 2.03(c), if the
     Administrative Agent receives for the account of the L/C Issuer any payment
     in respect of the related Unreimbursed Amount or interest thereon (whether

<PAGE>

     directly from the Borrower or otherwise, including proceeds of Cash
     Collateral applied thereto by the Administrative Agent), the Administrative
     Agent will distribute to such Lender its Pro Rata Share thereof
     (appropriately adjusted, in the case of interest payments, to reflect the
     period of time during which such Lender's L/C Advance was outstanding) in
     the same funds as those received by the Administrative Agent.

           (ii)  If any payment received by the Administrative Agent for the
     account of the L/C Issuer pursuant to Section 2.03(c)(i) is required to be
     returned under any of the circumstances described in Section 11.06
     (including pursuant to any settlement entered into by the L/C Issuer in its
     discretion), each Lender shall pay to the Administrative Agent for the
     account of the L/C Issuer its Pro Rata Share thereof on demand of the
     Administrative Agent, plus interest thereon from the date of such demand to
     the date such amount is returned by such Lender, at a rate per annum equal
     to the Federal Funds Rate from time to time in effect.

     (e)   Obligations Absolute. The obligation of the Borrower to reimburse the
L/C Issuer for each drawing under each Letter of Credit and to repay each L/C
Borrowing shall be absolute, unconditional and irrevocable, and shall be paid
strictly in accordance with the terms of this Agreement under all circumstances,
including the following:

           (i)   any lack of validity or enforceability of such Letter of
     Credit, this Agreement, any other Loan Document or any other agreement or
     instrument relating thereto;

           (ii)  the existence of any claim, counterclaim, set-off, defense or
     other right that the Borrower or any other Loan Party or Petro may have at
     any time against any beneficiary or any transferee of such Letter of Credit
     (or any Person for whom any such beneficiary or any such transferee may be
     acting), the L/C Issuer or any other Person, whether in connection with
     this Agreement, the transactions contemplated hereby or by such Letter of
     Credit or any agreement or instrument relating thereto, or any unrelated
     transaction;

           (iii) any draft, demand, certificate or other document presented
     under such Letter of Credit proving to be forged, fraudulent, invalid or
     insufficient in any respect or any statement therein being untrue or
     inaccurate in any respect; or any loss or delay in the transmission or
     otherwise of any document required in order to make a drawing under such
     Letter of Credit;

           (iv)  any payment by the L/C Issuer under such Letter of Credit
     against presentation of a draft or certificate that does not comply with
     the terms of such Letter of Credit except where such payment constitutes
     gross negligence or willful misconduct on the part of the L/C Issuer; or
     any payment made by the L/C Issuer under such Letter of Credit to any
     Person purporting to be a trustee in bankruptcy, debtor-in-possession,
     assignee for the benefit of creditors, liquidator, receiver or other
     representative of or successor to any beneficiary or any transferee of such
     Letter of Credit, including any arising in connection with any proceeding
     under any Debtor Relief Law; or

           (v)   any other circumstance or happening whatsoever, whether or not
     similar to any of the foregoing, including any other circumstance that
     might otherwise constitute a defense available to, or a discharge of, the
     Borrower or any other Loan Party or Petro, except for any such circumstance
     or happening which constitutes gross negligence or willful misconduct on
     the part of the L/C Issuer.

The Borrower shall promptly examine a copy of each Letter of Credit and each
amendment thereto that is delivered to it and, in the event of any claim of
noncompliance with the Borrower's instructions or other

<PAGE>

irregularity, the Borrower will immediately notify the L/C Issuer. The Borrower
shall be conclusively deemed to have waived any such claim against the L/C
Issuer and its correspondents unless such notice is given as aforesaid.

     (f)   Role of L/C Issuer. Each Lender and the Borrower agree that, in
paying any drawing under a Letter of Credit, the L/C Issuer shall not have any
responsibility to obtain any document (other than any sight draft, certificates
and documents expressly required by the Letter of Credit) or to ascertain or
inquire as to the validity or accuracy of any such document or the authority of
the Person executing or delivering any such document. None of the L/C Issuer,
any Agent-Related Person or any of the respective correspondents, participants
or assignees of the L/C Issuer shall be liable to any Lender for (i) any action
taken or omitted in connection herewith at the request or with the approval of
the Lenders or the Required Lenders, as applicable; (ii) any action taken or
omitted in the absence of gross negligence or willful misconduct; or (iii) the
due execution, effectiveness, validity or enforceability of any document or
instrument related to any Letter of Credit or Letter of Credit Application. The
Borrower hereby assumes all risks of the acts or omissions of any beneficiary or
transferee with respect to its use of any Letter of Credit; provided, however,
that this assumption is not intended to, and shall not, preclude the Borrower's
pursuing such rights and remedies as it may have against the beneficiary or
transferee at law or under any other agreement. None of the L/C Issuer, any
Agent-Related Person or any of the respective correspondents, participants or
assignees of the L/C Issuer shall be liable or responsible for any of the
matters described in clauses (i) through (v) of Section 2.03(e); provided,
however, that, anything in such clauses to the contrary notwithstanding, the
Borrower may have a claim against the L/C Issuer, and the L/C Issuer may be
liable to the Borrower, to the extent, but only to the extent, of any direct, as
opposed to consequential or exemplary, damages suffered by the Borrower which
the Borrower proves were caused by the L/C Issuer's willful misconduct or gross
negligence or the L/C Issuer's willful failure to pay under any Letter of Credit
after the presentation to it by the beneficiary of a sight draft and
certificate(s) strictly complying with the terms and conditions of a Letter of
Credit. In furtherance and not in limitation of the foregoing, the L/C Issuer
may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary, and the L/C Issuer shall not be responsible for the
validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

     (g)   Cash Collateral. Upon the request of the Administrative Agent, (i) if
the L/C Issuer has honored any full or partial drawing request under any Letter
of Credit and such drawing has resulted in an L/C Borrowing, or (ii) if, as of
the Letter of Credit Expiration Date, any Letter of Credit for any reason
remains outstanding and partially or wholly undrawn, the Borrower shall
immediately Cash Collateralize the then Outstanding Amount of all L/C
Obligations (in an amount equal to such Outstanding Amount determined as of the
date of such L/C Borrowing or the Letter of Credit Expiration Date, as the case
may be); provided, however, that the Borrower shall not be obligated to Cash
Collateralize any L/C Borrowing pursuant to clause (i) preceding which was
unable to be refinanced as a Borrowing of Revolving Loans, at a time when all
conditions precedent set forth in Section 5.02 were satisfied, on the date of
such drawing solely because such drawing occurred after 11:00 a.m., so long as
such L/C Borrowing is fully reimbursed or refinanced as a Borrowing of Revolving
Loans on the next succeeding Business Day). For purposes hereof, "Cash
Collateralize" means to pledge and deposit with or deliver to the Administrative
Agent, for the benefit of the L/C Issuer and the Lenders, as collateral for the
L/C Obligations, cash or deposit account balances pursuant to documentation in
form and substance satisfactory to the Administrative Agent and the L/C Issuer
(which documents are hereby consented to by the Lenders). Derivatives of such
term have corresponding meanings. The Borrower hereby grants to the
Administrative Agent, for the benefit of the L/C Issuer and the Lenders, a
security interest in all such cash, deposit accounts and all balances therein
and all proceeds of the foregoing. Unless otherwise permitted by the
Administrative Agent, cash collateral shall be maintained in blocked deposit
accounts at Wells Fargo.

     (h)   Applicability of ISP98 and UCP. Unless otherwise expressly agreed by
the L/C Issuer and the Borrower when a Letter of Credit is issued (including any
such agreement applicable to an Existing Letter of Credit), (i) the rules of the
"International Standby Practices 1998" (or such later version thereof as may be
in effect at the time of issuance) published by the Institute of International
Banking Law & Practice (the "ISP98") shall apply to each standby Letter of
Credit, and (ii) the rules of the Uniform Customs and Practice for Documentary
Credits, as most recently published by the International Chamber of Commerce
(the "ICC") at the time of issuance (including the ICC decision published by the
Commission on Banking Technique and Practice on April 6, 1998 regarding the
European single currency (euro)) shall apply to each commercial Letter of
Credit.

     (i)   Letter of Credit Fees. The Borrower shall pay to the Administrative
Agent for the account of each Lender in accordance with its Pro Rata Share (i) a
Letter of Credit fee for each commercial Letter of Credit equal to the
Applicable Rate times the daily maximum amount available to be drawn under such
Letter of Credit (whether or not such maximum amount is then in effect under
such Letter of Credit) and (ii) a Letter of Credit fee for each standby Letter
of Credit equal to the Applicable Rate times the daily maximum amount available
to be drawn under such Letter of Credit (whether or not such maximum amount is
then in effect under such Letter of Credit) (collectively, the "Letter of Credit
Fees"). Such Letter of Credit Fees shall be computed on a quarterly basis in
arrears and shall be due and payable on the last Business Day of each March,
June, September and December, commencing with the first such date to occur after
the issuance of such Letter of Credit, on the Letter of Credit Expiration Date
and thereafter on demand. If there is any change in the Applicable Rate during
any quarter, the daily maximum amount of each Letter of Credit shall be computed
and multiplied by the Applicable Rate separately for each period during such
quarter that such Applicable Rate was in effect.

     (j)   Fronting Fee and Documentary and Processing Charges Payable to L/C
Issuer. The Borrower shall pay directly to the L/C Issuer for its own account a
fronting fee with respect to each outstanding Letter of Credit in an amount
equal to the greater of $250 or the daily average amount available to be drawn
under such outstanding Letter of Credit multiplied by 0.25% per annum. Each such
fronting fee shall be due and payable (i) upon issuance of each Letter of Credit
and (ii) quarterly thereafter on the same day of each third month after the date
of issuance commencing with the first such date to occur after the issuance of
such Letter of Credit and continuing on the same day of each third month
thereafter. In addition, the Borrower shall, with respect to each Letter of
Credit issued, pay directly to the L/C Issuer for its own account the customary
issuance, presentation, amendment and other processing fees, and other standard
costs and charges, of the L/C Issuer relating to letters of credit as from time
to time in effect. Such customary fees and standard costs and charges are due
and payable on demand and are nonrefundable.

     (k)   Conflict with Letter of Credit Application. In the event of any
conflict between the terms hereof and the terms of any Letter of Credit
Application, the terms hereof shall control.

     (l)   Letters of Credit Issued for Subsidiaries. Notwithstanding that a
Letter of Credit issued or outstanding hereunder is in support of any
obligations of, or is for the account of, a Subsidiary, the Borrower shall be
obligated to reimburse the L/C Issuer hereunder for any and all drawings under
such Letter of Credit. The Borrower hereby acknowledges that the issuance of
Letters of Credit for the account or benefit of Subsidiaries inures to the
benefit of the Borrower, and that the Borrower's business derives substantial
benefits from the businesses of such Subsidiaries.

     2.05  Prepayments.

     (a)   Voluntary Prepayments of Loans. The Borrower may, upon notice from
the Borrower to the Administrative Agent, at any time or from time to time
voluntarily prepay Revolving Loans and the Term Loan in whole or in part without
premium or penalty; provided that (i) such notice must be received by the
Administrative Agent not later than 11:00 a.m. (A) three Business Days prior to
any date of prepayment of Eurodollar Rate Loans, and (B) on the date of
prepayment of Base Rate Loans; (ii) any such prepayment of Eurodollar Rate Loans
shall be in a principal amount of $1,000,000 or a whole multiple of $500,000 in
excess thereof (or, if less, the entire principal amount thereof then
outstanding); (iii) any such prepayment of Base Rate Loans shall be in a
principal amount of $500,000 or a whole multiple of $100,000 in excess thereof
(or, if less, the entire principal amount thereof then outstanding) and (iv) any
such prepayment of the Term Loan shall be applied ratably to all then remaining
principal amortization payments thereunder. Each such notice shall specify the
date and amount of such prepayment, whether such prepayment is a prepayment of
the Revolving Loans or the Term Loan and the Type(s) of Loans to be prepaid. The
Administrative Agent will promptly notify each Lender of its receipt of each
such notice, and of the amount of such Lender's Pro Rata Share of such
prepayment. If such notice is given by the Borrower, the Borrower shall make
such prepayment and the payment amount specified in such notice shall be due and
payable on the date specified therein. Any prepayment of a Eurodollar Rate Loan
shall be accompanied by all accrued interest thereon, together with any
additional amounts required pursuant to Section 3.05. Each such prepayment shall
be applied to the Loans of the Lenders in accordance with their respective Pro
Rata Shares.

     (b)   Mandatory Prepayments of Loans.

           (i)   Aggregate Revolving Commitments; Revolving Loans. If for any
     reason the Total Revolving Outstandings at any time exceed the Aggregate
     Revolving Commitments then in effect, the Borrower shall immediately prepay
     Revolving Loans and/or Cash Collateralize the L/C Obligations in an
     aggregate amount equal to such excess; provided, however, that the Borrower
     shall not be required to Cash Collateralize the L/C Obligations pursuant to
     this Section 2.05(b)(i) unless, after the prepayment in full of the
     Revolving Loans, the Total Revolving Outstandings exceed the Aggregate
     Revolving Commitments then in effect. In addition, the Borrower shall
     prepay the Revolving Loans by an amount equal to 100% of the Net Cash
     Proceeds of each Disposition or Involuntary Disposition referred to in
     clause (ii) of Section 2.05(b) if and to the extent that such Net Cash
     Proceeds are required to be reinvested in a Replacement Asset in accordance
     with such clause (ii), each of which prepayments shall be due and payable
     on or before three Business Days after the receipt of any such Net Cash
     Proceeds or, if and to the extent that such prepayment would require the
     Borrower to compensate the Lenders for any funding losses referred to in
     clause (a) of Section 3.05, on the first Business Day on which such
     compensation will not be required to be so paid (and each of which
     prepayments may be thereafter re-advanced as Revolving Loans, if and to the
     extent otherwise permitted by this Agreement, in connection with such
     required reinvestments).

           (ii)  Dispositions and Involuntary Dispositions. The Borrower shall
     prepay the Loans and, if and to the extent required by clause (B) of
     Section 2.05(b)(vi), Cash Collateralize the L/C Obligations as hereafter
     provided in an aggregate amount equal to 100% of the Net Cash Proceeds of
     all Dispositions (other than Dispositions permitted under clauses (a), (d),
     (e), (f), (g) and (h) of Section 8.05) and Involuntary Dispositions to the
     extent (A) such Net Cash Proceeds are not reinvested in a Replacement Asset
     (1) in the case of a Disposition, within 180 days of the date of such
     Disposition, or (2) in the case of an Involuntary Disposition, within 540
     days after the date of such Involuntary Disposition or (B) in the case of
     Dispositions (as opposed to Involuntary Dispositions) only, the aggregate
     amount of such Net Cash Proceeds of all

<PAGE>

     Dispositions received by any one or more of the Borrower and its
     Subsidiaries shall exceed $4,000,000 in any fiscal year; provided, however,
     that, for purposes of clause (b) of Section 8.05, Net Cash Proceeds shall
     not include the amount of such proceeds required to purchase the
     replacement equipment as required by such clause. Such prepayment shall be
     due immediately upon the expiration of the 180 day or 540 day (as
     applicable) period set forth in clause (A) preceding (to the extent such
     prepayment is required by virtue of such clause (A)) or immediately upon
     the receipt of Net Cash Proceeds in excess of $4,000,000 in any fiscal year
     (to the extent such prepayment is required by virtue of clause (B)
     preceding), as applicable, and shall be applied as set forth in clause (vi)
     below.

           (iii) Debt Issuances. Immediately upon receipt by any Loan Party of
     the Net Cash Proceeds of any Debt Issuance, the Borrower shall prepay the
     Loans and, if and to the extent required by clause (B) of Section
     2.05(b)(vi), Cash Collateralize the L/C Obligations as hereafter provided
     in an aggregate amount equal to 100% of such Net Cash Proceeds (such
     prepayment to be applied as set forth in clause (vi) below), provided,
     however, that, with respect to any Debt Issuance or Debt Issuances by
     Holdings and/or Petro Holdings, Net Cash Proceeds thereof in an aggregate
     amount not to exceed $5,000,000 may be received without the necessity of
     any corresponding prepayment pursuant to this clause (iii).

           (iv)  Equity Issuances. Immediately upon the receipt by any Loan
     Party of the Net Cash Proceeds of any Equity Issuance, the Borrower shall
     prepay the Loans and, if and to the extent required by clause (B) of
     Section 2.05(b)(vi), Cash Collateralize the L/C Obligations in an aggregate
     amount equal to 100% of such Net Cash Proceeds (such prepayment to be
     applied as set forth in clause (vi) below); provided, however, that, with
     respect to any Equity Issuance or Equity Issuances by Holdings and/or Petro
     Holdings, Net Cash Proceeds thereof in an aggregate amount not to exceed
     $5,000,000 may be received without the necessity of any corresponding
     prepayment pursuant to this clause (iv).

           (v)   Excess Cash Flow. On or before March 31st of each calendar
     year, commencing March 31, 2005, the Borrower shall prepay the Loans and,
     if and to the extent required by clause (B) of Section 2.05(b)(vi), Cash
     Collateralize the L/C Obligations in an aggregate amount equal to 75% of
     Excess Cash Flow for the immediately preceding calendar year (such
     prepayment to be applied as set forth in clause (vi) below).

           (vi)  Application of Mandatory Prepayments. All amounts required to
     be paid pursuant to this Section 2.05(b) shall be applied as follows:

                 (A)  with respect to all amounts prepaid pursuant to Section
           2.05(b)(i), to Revolving Loans and (after all Revolving Loans have
           been repaid) to Cash Collateralize L/C Obligations; and

                 (B)  with respect to all amounts prepaid pursuant to Section
           2.05(b)(ii), (iii), (iv) and (v), first, to the Term Loan, ratably to
           all then remaining principal amortization payments, then (after the
           Term Loan has been paid in full) to the Revolving Loans (but without
           any reduction in the Aggregate Revolving Commitments except as
           provided in Section 2.06(b)) and then (after all Revolving Loans have
           been repaid), if a Default has then occurred and is continuing and
           the Administrative Agent so requests or if required by Section
           2.03(g), to Cash Collateralize L/C Obligations (but without any
           reduction in the Aggregate Revolving Commitments except as provided
           in Section 2.06(b)).

<PAGE>

           Within the parameters of the applications set forth above,
           prepayments shall be applied first to Base Rate Loans and then to
           Eurodollar Rate Loans in direct order of Interest Period maturities.
           All prepayments under this Section 2.05(b) shall be subject to
           Section 3.05, but otherwise without premium or penalty, and shall be
           accompanied by interest on the principal amount prepaid through the
           date of prepayment.

     2.06  Termination or Reduction of Aggregate Revolving Commitments.

     (a)   The Borrower may, upon notice from the Borrower to the Administrative
Agent, terminate the Aggregate Revolving Commitments or from time to time
permanently reduce the Aggregate Revolving Commitments; provided that (i) any
such notice shall be received by the Administrative Agent not later than 11:00
a.m. five Business Days prior to the date of termination or reduction, (ii) any
such partial reduction shall be in an aggregate amount of $1,000,000 or any
whole multiple of $100,000 in excess thereof, (iii) the Borrower shall not
terminate or reduce the Aggregate Revolving Commitments if, after giving effect
thereto and to any concurrent prepayments hereunder, the aggregate Outstanding
Amount of Revolving Loans and L/C Obligations is greater than zero and shall not
reduce the Aggregate Revolving Commitments if, after giving effect thereto and
to any concurrent prepayments hereunder, the aggregate Outstanding Amount of
Revolving Loans and L/C Obligations would exceed the Aggregate Revolving
Commitments, and (iv) if, after giving effect to any reduction of the Aggregate
Revolving Commitments or the Letter of Credit Sublimit exceeds the amount of the
Aggregate Revolving Commitments, such sublimit shall be automatically reduced by
the amount of such excess.

     (b)   The Aggregate Revolving Commitments shall be reduced by an amount
equal to the aggregate amount of all Net Cash Proceeds of all Dispositions and
Involuntary Dispositions which are applied, in accordance with clause (B) of
Section 2.05(b)(vi), to the Revolving Loans and/or to Cash Collateralize L/C
Obligations, in each case if and to the extent (but only if and to the extent)
that such reduction of the Aggregate Revolving Commitments is required by the
Borrower Senior Notes Indenture as a condition to permitting such prepayment of
the Revolving Loans and/or Cash Collateralization of L/C Obligations thereunder.
Each such reduction of the Aggregate Revolving Commitments shall occur on the
later to occur of the date upon which the corresponding mandatory prepayment is
required to be made in accordance with Section 2.05(b)(ii) or the initial date
upon which such reduction is required by the Borrower Senior Notes Indenture.

     (c)   The Administrative Agent will promptly notify the Lenders of any such
notice of termination or reduction of the Aggregate Revolving Commitments. Any
reduction of the Aggregate Revolving Commitments shall be applied to the
Revolving Commitment of each Lender according to its Pro Rata Share. All
commitment fees accrued until the effective date of any termination of the
Aggregate Revolving Commitments shall be paid on the effective date of such
termination.

     2.07  Repayment of Loans.

     (a)   Revolving Loans. The Borrower shall repay to the Lenders on the
Revolving Loans Maturity Date the aggregate principal amount of all Revolving
Loans outstanding on such date.

     (b)   Term Loan. The Borrower shall repay the outstanding principal amount
of the Term Loan in installments on the dates and in the amounts set forth in
the table below (as such installments may hereafter be adjusted as a result of
prepayments made pursuant to Section 2.05), unless accelerated sooner pursuant
to Section 9.02:

     2.08  Interest.

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

     (b)   If any principal amount of any Loan or other amount payable by the
Borrower under any Loan Document is not paid when due (without regard to any
applicable grace periods), whether at stated maturity, by acceleration or
otherwise, then such amount shall thereafter bear interest at a fluctuating
interest rate per annum at all times equal to the Default Rate to the fullest
extent permitted by applicable Laws. Accrued and unpaid interest on past due
amounts (including interest on past due interest) shall be due and payable upon
demand. In addition and in lieu of the otherwise applicable interest rate under
this Agreement, at all times during which an Event of Default has occurred and
is continuing, the principal amount of the Loans and, upon the request of the
Required Lenders (and to the extent of such request) and to the fullest extent
permitted by applicable Laws, any other amount payable by the Borrower under any
Loan Document shall bear interest at a fluctuating interest rate per annum at
all times equal to the Default Rate to the fullest extent permitted by
applicable Laws.

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

     2.09  Fees. In addition to certain fees described in subsections (i) and
(j) of Section 2.03:

     (a)   Commitment Fee. The Borrower shall pay to the Administrative Agent,
for the account of each Lender in accordance with its Pro Rata Share, a
commitment fee equal to the product of (i) the Applicable Rate times (ii) the
actual daily amount by which the Aggregate Revolving Commitments

<PAGE>

exceed the sum of (A) the Outstanding Amount of Revolving Loans and (B) the
Outstanding Amount of L/C Obligations. The commitment fee shall accrue at all
times during the Availability Period, including at any time during which one or
more of the conditions in Article V is not met, and shall be due and payable
quarterly in arrears on the last Business Day of each March, June, September and
December, commencing with the first such date to occur after the Closing Date,
and on the Revolving Loans Maturity Date. The commitment fee shall be calculated
quarterly in arrears, and if there is any change in the Applicable Rate during
any quarter, the actual daily amount shall be computed and multiplied by the
Applicable Rate separately for each period during such quarter that such
Applicable Rate was in effect.

     (b)   Other Fees.

           (i)   The Borrower shall pay to Wells Fargo, for its own account,
     fees in the amounts and at the times specified in the Wells Fargo Fee
     Letter. The Borrower shall pay to the Arranger and Bank of America, for
     their own respective accounts, fees in the amounts and at the times
     specified in the Bank of America Fee Letter. Such fees shall be fully
     earned when paid and shall not be refundable for any reason whatsoever.

           (ii)  The Borrower shall pay to the Lenders such fees as shall have
     been separately agreed upon in writing in the amounts and at the times so
     specified. Such fees shall be fully earned when paid and shall not be
     refundable for any reason whatsoever.

     2.10  Computation of Interest and Fees. All computations of interest for
Base Rate Loans when the Base Rate is determined by Wells Fargo's "prime rate"
shall be made on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed. All other computations of fees and interest shall be made
on the basis of a 360-day year and actual days elapsed (which results in more
fees or interest, as applicable, being paid than if computed on the basis of a
365-day year). Interest shall accrue on each Loan for the day on which the Loan
is made, and shall not accrue on a Loan, or any portion thereof, for the day on
which the Loan or such portion is paid, provided that any Loan that is repaid on
the same day on which it is made shall, subject to Section 2.12(a), bear
interest for one day.

     2.11  Evidence of Debt.

     (a)   The Credit Extensions made by each Lender shall be evidenced by one
or more accounts or records maintained by such Lender and by the Administrative
Agent in the ordinary course of business. The accounts or records maintained by
the Administrative Agent and each Lender shall be conclusive absent manifest
error of the amount of the Credit Extensions made by the Lenders to the Borrower
and the interest and payments thereon. Any failure to so record or any error in
doing so shall not, however, limit or otherwise affect the obligation of the
Borrower hereunder to pay any amount owing with respect to the Obligations. In
the event of any conflict between the accounts and records maintained by any
Lender and the accounts and records of the Administrative Agent in respect of
such matters, the accounts and records of the Administrative Agent shall control
in the absence of manifest error. Upon the request of any Lender made through
the Administrative Agent, the Borrower shall execute and deliver to such Lender
(through the Administrative Agent) a promissory note, which shall evidence such
Lender's Loans in addition to such accounts or records. Each such promissory
note shall (ii) in the case of Revolving Loans, be in the form of Exhibit B-1 (a
"Revolving Note") and (ii) in the case of the Term Loan, be in the form of
Exhibit B-2 (a "Term Note"). Each Lender may attach schedules to its Note and
endorse thereon the date, Type (if applicable), amount and maturity of its Loans
and payments with respect thereto.

     (b)   In addition to the accounts and records referred to in subsection
(a), each Lender and the Administrative Agent shall maintain in accordance with
its usual practice accounts or records evidencing the purchases and sales by
such Lender of participations in Letters of Credit. In the event of any conflict

<PAGE>

between the accounts and records maintained by the Administrative Agent and the
accounts and records of any Lender in respect of such matters, the accounts and
records of the Administrative Agent shall control in the absence of manifest
error.

     2.12  Payments Generally.

     (a)   All payments to be made by the Borrower shall be made without
condition or deduction for any counterclaim, defense, recoupment or setoff.
Except as otherwise expressly provided herein, all payments by the Borrower
hereunder shall be made to the Administrative Agent, for the account of the
respective Lenders to which such payment is owed, at the Administrative Agent's
Office in Dollars and in immediately available funds not later than 2:00 p.m. on
the date specified herein. The Administrative Agent will promptly distribute to
each Lender its Pro Rata Share (or other applicable share as provided herein) of
such payment in like funds as received by wire transfer to such Lender's Lending
Office. All payments received by the Administrative Agent after 2:00 p.m. shall
be deemed received on the next succeeding Business Day and any applicable
interest or fee shall continue to accrue.

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

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

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

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

           (ii)  if any Lender failed to make such payment, such Lender shall
     forthwith on demand pay to the Administrative Agent the amount thereof in
     immediately available funds, together with interest thereon for the period
     from the date such amount was made available by the Administrative Agent to
     the Borrower to the date such amount is recovered by the Administrative
     Agent (the "Compensation Period") at a rate per annum equal to the Federal
     Funds Rate from time to time in effect. If such Lender pays such amount to
     the Administrative Agent, then such

<PAGE>

     amount shall constitute such Lender's Loan included in the applicable
     Borrowing. If such Lender does not pay such amount forthwith upon the
     Administrative Agent's demand therefor, the Administrative Agent may make a
     demand therefor upon the Borrower, and the Borrower shall pay such amount
     to the Administrative Agent, together with interest thereon for the
     Compensation Period at a rate per annum equal to the rate of interest
     applicable to the applicable Borrowing. Nothing herein shall be deemed to
     relieve any Lender from its obligation to fulfill its Commitment or to
     prejudice any rights which the Administrative Agent or the Borrower may
     have against any Lender as a result of any default by such Lender
     hereunder.

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

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

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

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

     2.13  Sharing of Payments. If, other than as expressly provided elsewhere
herein, any Lender shall obtain on account of the Loans made by it, or the
participations in L/C Obligations held by it, any payment (whether voluntary,
involuntary, through the exercise of any right of set-off or otherwise) in
excess of its ratable share (or other share contemplated hereunder) thereof,
such Lender shall immediately (a) notify the Administrative Agent of such fact,
and (b) purchase from the other Lenders such participations in the Loans made by
them and/or such subparticipations in the participations in L/C Obligations held
by them, as the case may be, as shall be necessary to cause such purchasing
Lender to share the excess payment in respect of such Loans or such
participations, as the case may be, pro rata with each of them; provided,
however, that if all or any portion of such excess payment is thereafter
recovered from the purchasing Lender under any of the circumstances described in
Section 11.06 (including pursuant to any settlement entered into by the
purchasing Lender in its discretion), such purchase shall to that extent be
rescinded and each other Lender shall repay to the purchasing Lender the
purchase price paid therefor, together with an amount equal to such paying
Lender's ratable share (according to the proportion of (i) the amount of such
paying Lender's required repayment to (ii) the total amount so recovered from
the purchasing Lender) of any interest or other amount paid or payable by the
purchasing Lender in respect of the total amount so recovered, without further
interest thereon. The Borrower agrees that any Lender so purchasing a
participation from another Lender may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 11.09) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or
repayments. Each Lender that purchases a

<PAGE>

participation pursuant to this Section shall from and after such purchase have
the right to give all notices, requests, demands, directions and other
communications under this Agreement with respect to the portion of the
Obligations purchased to the same extent as though the purchasing Lender were
the original owner of the Obligations purchased.

                                   ARTICLE III

                     TAXES, YIELD PROTECTION AND ILLEGALITY

     3.01  Taxes.

     (a)   Any and all payments by any Loan Party or Petro to or for the account
of either Agent or any Lender under any Loan Document shall be made free and
clear of and without deduction for any and all present or future taxes, duties,
levies, imposts, deductions, assessments, fees, withholdings or similar charges,
and all liabilities with respect thereto, excluding, in the case of each Agent
and each Lender, taxes imposed on or measured by its overall net income, and
franchise taxes imposed on it (in lieu of net income taxes), by the jurisdiction
(or any political subdivision thereof) under the Laws of which such Agent or
such Lender, as the case may be, is organized or maintains a lending office (all
such non-excluded taxes, duties, levies, imposts, deductions, assessments, fees,
withholdings or similar charges, and liabilities being hereinafter referred to
as "Taxes"). If any Loan Party or Petro shall be required by any Laws to deduct
any Taxes from or in respect of any sum payable under any Loan Document to
either Agent or any Lender, (i) the sum payable shall be increased as necessary
so that, after making all required deductions (including deductions applicable
to additional sums payable under this Section), each of such Agent and such
Lender receives an amount equal to the sum it would have received had no such
deductions been made, (ii) such Loan Party or Petro, respectively, shall make
such deductions, (iii) such Loan Party or Petro, respectively, shall pay the
full amount deducted to the relevant taxation authority or other authority in
accordance with applicable Laws, and (iv) within 30 days after the date of such
payment, such Loan Party or Petro, respectively, shall furnish to the
Administrative Agent (which shall forward the same to such Lender) the original
or a certified copy of a receipt evidencing payment thereof.

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

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

     (d)   The Borrower agrees to indemnify each Agent and each Lender for (i)
the full amount of Taxes and Other Taxes (including any Taxes or Other Taxes
imposed or asserted by any jurisdiction on amounts payable under this Section)
paid by such Agent and such Lender, (ii) amounts payable under Section 3.01(c)
and (iii) any liability (including additions to tax, penalties, interest and
expenses) arising therefrom or with respect thereto, in each case whether or not
such Taxes or Other Taxes were correctly or legally imposed or asserted by the
relevant Governmental Authority. Payment under this subsection (d) shall be made
within 30 days after the date the Lender or the Administrative Agent makes a
demand therefor.

<PAGE>

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

     3.03  Inability to Determine Rates. If the Administrative Agent determines
that for any reason adequate and reasonable means do not exist for determining
the Eurodollar Base Rate for any requested Interest Period with respect to a
proposed Eurodollar Rate Loan, or that the Eurodollar Base Rate for any
requested Interest Period with respect to a proposed Eurodollar Rate Loan does
not adequately and fairly reflect the cost to the Lenders of funding such Loan,
the Administrative Agent will promptly notify the Borrower and all Lenders.
Thereafter, the obligation of the Lenders to make or maintain Eurodollar Rate
Loans shall be suspended until the Administrative Agent revokes such notice.
Upon receipt of such notice, the Borrower may revoke any pending request for a
Borrowing of, conversion to or continuation of Eurodollar Rate Loans or, failing
that, will be deemed to have converted such request into a request for a
Borrowing of Base Rate Loans in the amount specified therein.

     3.04  Increased Cost and Reduced Return; Capital Adequacy.

     (a)   If any Lender determines that, as a result of the introduction of or
any change in or in the interpretation of any Law, or such Lender's compliance
therewith, there shall be any increase in the cost to such Lender of agreeing to
make or making, funding or maintaining Eurodollar Rate Loans or (as the case may
be) issuing or participating in Letters of Credit, or a reduction in the amount
received or receivable by such Lender in connection with any of the foregoing
(excluding for purposes of this subsection (a) any such increased costs or
reduction in amount resulting from (i) Taxes or Other Taxes (as to which Section
3.01 shall govern), (ii) changes in the basis of taxation of overall net income
or overall gross income by the United States or any foreign jurisdiction or any
political subdivision of either thereof under the Laws of which such Lender is
organized or has its Lending Office, and (iii) reserve requirements utilized, as
to Eurodollar Rate Loans, in the determination of the Eurodollar Rate), then,
from time to time upon demand of such Lender (with a copy of such demand to the
Administrative Agent), the Borrower shall pay to such Lender such additional
amounts as will compensate such Lender for such increased cost or reduction.

     (b)   If any Lender determines that the introduction of any Law regarding
capital adequacy or any change therein or in the interpretation thereof, or
compliance by such Lender (or its Lending Office) therewith, has the effect of
reducing the rate of return on the capital of such Lender or any corporation
controlling such Lender as a consequence of such Lender's obligations hereunder
(taking into consideration its policies with respect to capital adequacy and
such Lender's desired return on capital), then, from time to time upon demand of
such Lender (with a copy of such demand to the Administrative

<PAGE>

Agent), the Borrower shall pay to such Lender such additional amounts as will
compensate such Lender for such reduction.

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

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

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

     (c)   any assignment of a Eurodollar Rate Loan on a day other than the last

the liquidation or reemployment of funds obtained by it to maintain such Loan or
from fees payable to terminate the deposits from which such funds were obtained.
The Borrower shall also pay any customary administrative fees charged by such
Lender in connection with the foregoing.

For purposes of calculating amounts payable by the Borrower to the Lenders under

Rate Loan made by it at the Eurodollar Base Rate used in determining the

period, whether or not such Eurodollar Rate Loan was in fact so funded.

paid to it hereunder shall be conclusive in the absence of manifest error. In
determining such amount, such Agent or such Lender may use any reasonable
averaging and attribution methods.

     (b)   Upon any Lender's making a claim for compensation under Section 3.01
or 3.04, the Borrower may replace such Lender in accordance with Section 11.16.

     3.07  Survival. All of the Borrower's obligations under this Article III
shall survive termination of the Aggregate Revolving Commitments and repayment
of all other Obligations hereunder.

                                   ARTICLE IV

                                    GUARANTY
                                    --------

     4.01  The Guaranty. Each of the Credit Agreement Guarantors hereby jointly
and severally and irrevocably guarantees to each Lender, each Affiliate of a
Lender that enters into a Swap Contract or a Treasury Management Agreement and
each Agent, as hereinafter provided, as primary obligor and not as surety, the
prompt payment of the Obligations in full when due (whether at stated maturity,
as a mandatory prepayment, by acceleration, as a mandatory cash
collateralization or otherwise) strictly in

<PAGE>

accordance with the terms thereof. The Credit Agreement Guarantors hereby
further agree that if any of the Obligations are not paid in full when due
(whether at stated maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise), the Credit Agreement Guarantors
will, jointly and severally, promptly pay the same, without any demand or notice
whatsoever, and that in the case of any extension of time of payment or renewal
of any of the Obligations, the same will be promptly paid in full when due
(whether at extended maturity, as a mandatory prepayment, by acceleration, as a
mandatory cash collateralization or otherwise) in accordance with the terms of
such extension or renewal.

     Notwithstanding any provision to the contrary contained herein or in any
other of the Loan Documents, Swap Contracts or Treasury Management Agreements,
the obligations of each Credit Agreement Guarantor under this Agreement and the
other Loan Documents shall be limited to an aggregate amount equal to the
largest amount that would not render such obligations subject to avoidance under
the Debtor Relief Laws or any comparable provisions of any applicable state law.

     4.02  Obligations Unconditional. The obligations of the Credit Agreement
Guarantors under Section 4.01 are joint and several, absolute and unconditional,
irrespective of the value, genuineness, validity, regularity or enforceability
of any of the Loan Documents, Swap Contracts or Treasury Management Agreements,
or any other agreement or instrument referred to therein, or any substitution,
release, impairment or exchange of any other guarantee of or security for any of
the Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 4.02 that the obligations of the Credit
Agreement Guarantors hereunder shall be absolute and unconditional under any and
all circumstances. Each Credit Agreement Guarantor agrees that such Guarantor
shall have no right of subrogation, indemnity, reimbursement or contribution
against the Borrower or any other Guarantor for amounts paid under this Article
IV until such time as the Obligations have been paid in full and all Commitments
and outstanding Letters of Credit have expired or terminated. Without limiting
the generality of the foregoing, it is agreed that, to the fullest extent
permitted by law, the occurrence of any one or more of the following shall not
alter or impair the liability of any Credit Agreement Guarantor hereunder, which
shall remain absolute and unconditional as described above:

     (a)   at any time or from time to time, without notice to any Guarantor,
the time for any performance of or compliance with any of the Obligations shall
be extended, or such performance or compliance shall be waived;

     (b)   any of the acts mentioned in any of the provisions of any of the Loan
Documents, any Swap Contract or Treasury Management Agreement between any Loan
Party or Petro and any Lender, or any Affiliate of a Lender, or any other
agreement or instrument referred to in the Loan Documents or such Swap Contracts
or Treasury Management Agreements shall be done or omitted;

     (c)   the maturity of any of the Obligations shall be accelerated, or any
of the Obligations shall be modified, supplemented or amended in any respect, or
any right under any of the Loan Documents, any Swap Contract or Treasury
Management Agreement between any Loan Party or Petro and any Lender, or any
Affiliate of a Lender, or any other agreement or instrument referred to in the
Loan Documents or such Swap Contracts or Treasury Management Agreements shall be
waived or any other guarantee of any of the Obligations or any security therefor
shall be released, impaired or exchanged in whole or in part or otherwise dealt
with;

     (d)   any Lien granted to, or in favor of, either Agent or any Lender or
Lenders as security for any of the Obligations shall fail to attach or be
perfected; or

<PAGE>

     (e)   any of the Obligations shall be determined to be void or voidable
(including, without limitation, for the benefit of any creditor of any
Guarantor) or shall be subordinated to the claims of any Person (including,
without limitation, any creditor of any Guarantor).

With respect to its obligations hereunder, each Credit Agreement Guarantor
hereby expressly waives diligence, presentment, demand of payment, protest and
all notices whatsoever, and any requirement that the Administrative Agent or any
Lender exhaust any right, power or remedy or proceed against any Person under
any of the Loan Documents or any Swap Contract or Treasury Management Agreement
between any Loan Party or Petro and any Lender, or any Affiliate of a Lender, or
any other agreement or instrument referred to in the Loan Documents or such Swap
Contracts or Treasury Management Agreement, or against any other Person under
any other guarantee of, or security for, any of the Obligations.

     4.03  Reinstatement. The obligations of the Credit Agreement Guarantors
under this Article IV shall be automatically reinstated if and to the extent
that for any reason any payment by or on behalf of any Person in respect of the
Obligations is rescinded or must be otherwise restored by any holder of any of
the Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Credit Agreement Guarantor agrees that it
will indemnify each Agent and each Lender on demand for all reasonable costs and
expenses (including, without limitation, fees and expenses of counsel) incurred
by such Agent or such Lender in connection with such rescission or restoration,
including any such costs and expenses incurred in defending against any claim
alleging that such payment constituted a preference, fraudulent transfer or
similar payment under any bankruptcy, insolvency or similar law.

     4.04  Certain Additional Waivers. Each Credit Agreement Guarantor agrees
that such Guarantor shall have no right of recourse to security for the
Obligations except through the exercise of rights of subrogation pursuant to
Section 4.02 and through the exercise of rights of contribution pursuant to
Section 4.06, and that all other rights of such recourse are hereby waived.

     4.05  Remedies. The Credit Agreement Guarantors agree that, to the fullest
extent permitted by law, as between the Credit Agreement Guarantors, on the one
hand, and the Agents and the Lenders, on the other hand, the Obligations may be
declared to be forthwith due and payable as provided in Section 9.02 (and shall
be deemed to have become automatically due and payable in the circumstances
provided in said Section 9.02) for purposes of Section 4.01 notwithstanding any
stay, injunction or other prohibition preventing such declaration (or preventing
the Obligations from becoming automatically due and payable) as against any
other Person and that, in the event of such declaration (or the Obligations
being deemed to have become automatically due and payable), the Obligations
(whether or not due and payable by any other Person) shall forthwith become due
and payable by the Credit Agreement Guarantors for purposes of Section 4.01. The
Credit Agreement Guarantors acknowledge and agree that their obligations
hereunder are secured in accordance with the terms of the Collateral Documents
and that the Lenders may exercise their remedies thereunder in accordance with
the terms thereof.

     4.06  Rights of Contribution. The Guarantors hereby agree as among
themselves that, if any Guarantor shall make an Excess Payment (as defined
below), such Guarantor shall have a right of contribution from each other
Guarantor in an amount equal to such other Guarantor's Contribution Share (as
defined below) of such Excess Payment. The payment obligations of any Guarantor
under this Section 4.06 shall be subordinate and subject in right of payment to
the Obligations until such time as the Obligations have been paid in full and
all Commitments and outstanding Letters of Credit have expired or terminated,
and none of the Guarantors shall exercise any right or remedy under this Section
4.06 against any other Guarantor until such Obligations have been paid in full
and all Commitments and outstanding Letters of Credit have expired or
terminated. For purposes of this Section 4.06:

<PAGE>

     (a)   "Excess Payment" shall mean the amount paid by any Guarantor in
excess of its Ratable Share of any Guaranteed Obligations;

     (b)   "Ratable Share" shall mean, for any Guarantor in respect of any
payment of Obligations, the ratio (expressed as a percentage) as of the date of
such payment of Guaranteed Obligations of (i) the amount by which the aggregate
present fair salable value of all of its assets and properties exceeds the
amount of all debts and liabilities of such Guarantor (including contingent,
subordinated, unmatured and unliquidated liabilities, but excluding the
obligations of such Guarantor hereunder) to (ii) the amount by which the
aggregate present fair salable value of all assets and other properties of all
of the Loan Parties and Petro exceeds the amount of all of the debts and
liabilities (including contingent, subordinated, unmatured and unliquidated
liabilities, but excluding the obligations of the Loan Parties hereunder and of
Petro under the Guaranty executed by it) of all of the Loan Parties and Petro;
provided, however, that, for purposes of calculating the Ratable Shares of the
Guarantors in respect of any payment of Obligations, any Guarantor that became a
Guarantor subsequent to the date of any such payment shall be deemed to have
been a Guarantor on the date of such payment and the financial information for
such Guarantor as of the date such Guarantor became a Guarantor shall be
utilized for such Guarantor in connection with such payment;

     (c)   "Contribution Share" shall mean, for any Guarantor in respect of any
Excess Payment made by any other Guarantor, the ratio (expressed as a
percentage) as of the date of such Excess Payment of (i) the amount by which the
aggregate present fair salable value of all of its assets and properties exceeds
the amount of all debts and liabilities of such Guarantor (including contingent,
subordinated, unmatured and unliquidated liabilities, but excluding the
obligations of such Guarantor hereunder) to (ii) the amount by which the
aggregate present fair salable value of all assets and other properties of the
Loan Parties and Petro other than the maker of such Excess Payment exceeds the
amount of all of the debts and liabilities (including contingent, subordinated,
unmatured and unliquidated liabilities, but excluding the obligations of the
Loan Parties hereunder and of Petro under the Guaranty executed by it) of the
Loan Parties and Petro other than the maker of such Excess Payment; provided,
however, that, for purposes of calculating the Contribution Shares of the
Guarantors in respect of any Excess Payment, any Guarantor that became a
Guarantor subsequent to the date of any such Excess Payment shall be deemed to
have been a Guarantor on the date of such Excess Payment and the financial
information for such Guarantor as of the date such Guarantor became a Guarantor
shall be utilized for such Guarantor in connection with such Excess Payment; and

     (d)   "Guaranteed Obligations" shall mean the Obligations guaranteed by the
Credit Agreement Guarantors pursuant to this Article IV or by any other
Guarantor pursuant to any other Guaranty.

This Section 4.06 shall not be deemed to affect any right of subrogation,
indemnity, reimbursement or contribution that any Guarantor may have under Law
against the Borrower in respect of any payment of Guaranteed Obligations;
provided, however, that none of the Guarantors shall exercise any such right
against the Borrower until all Obligations have been paid in full and all
Commitments have expired or terminated. Notwithstanding the foregoing, all
rights of contribution against any Guarantor shall terminate from and after such
time, if ever, that such Guarantor shall be relieved of its obligations in
accordance with Section 10.11.

     4.07  Guarantee of Payment; Continuing Guarantee. The guarantee in this
Article IV is a guaranty of payment and not of collection, is a continuing
guarantee and shall apply to all Obligations whenever arising.

<PAGE>

made to Article XI of the Borrower Senior Notes Indenture and that certain
Guarantee of the Borrower Senior Notes Indenture executed by Holdings, Petro
Holdings, Petro and Petro Distributing pursuant to which such Guarantors
Guarantee the Borrower Senior Notes and related obligations (collectively, as
the same may be amended, modified, extended, restated or supplemented from time
to time, the "Indenture Guaranty"). In addition to each Credit Agreement
Guarantor's obligations contained elsewhere in this Article IV and in addition
to the rights, powers and remedies available to the Agents and the Lenders
provided elsewhere in this Article IV, each of the Credit Agreement Guarantors
acknowledges and agrees that (a) it shall have the same obligations with respect
to its Guarantee of the Obligations provided pursuant to this Article IV as the
obligations it has with respect to its Indenture Guaranty and (b) the Agents and
the Lenders shall have the same rights, powers and remedies with respect to its
Guarantee of the Obligations provided pursuant to this Article IV as each
"Holder" and the "Trustee" (as such terms are defined in the Borrower Senior
Notes Indenture) have with respect to the Indenture Guarantee, which obligations
referred to in clause (a) preceding and which rights, powers and remedies
referred to in clause (b) preceding are hereby incorporated herein by reference
and made a part of this Article IV, mutatis mutandis, as if set forth herein.

     4.09  Subordination. The payment of any amounts due with respect to any
Indebtedness of the Borrower for money borrowed or credit received now or
hereafter owed to any Credit Agreement Guarantor shall be subordinate and
subject in right of payment to the Obligations until such time as the
Obligations have been paid in full and all Commitments and outstanding Letters
of Credit have expired or terminated, and each Credit Agreement Guarantor agrees
that, after the occurrence and during the continuance of any Event of Default,
it shall not exercise any right or remedy under, pursuant to or in connection
with any such Indebtedness until such time as the Obligations have been paid in
full and all Commitments and outstanding Letters of Credit have expired or
terminated. If, notwithstanding the foregoing sentence, after the occurrence and
during the continuance of an Event of Default, any Credit Agreement Guarantor
shall collect, enforce or receive any amounts in respect of such Indebtedness
while any Obligations, Commitments or Letters of Credit are still outstanding,
such amounts shall be collected, enforced and received by such Credit Agreement
Guarantor as trustee for the Administrative Agent and the Lenders and be paid
over to the Administrative Agent, for the benefit of the Lenders, on account of
the Obligations without affecting in any manner the liability of any Credit
Agreement Guarantor under the other provisions of this Article IV.
Notwithstanding anything to the contrary contained in this Section 4.09, any
trade payables between the Borrower and its Subsidiaries shall not be subject to
this Section 4.09.

     6.07  No Default.

     (b)   No Default has occurred and is continuing or would result from the
consummation of the Transactions.

     6.08  Ownership of Property; Liens. Each of the Borrower and its

Parties of such Liens on its Properties, do not result in any fraudulent
transfer or fraudulent conveyance within the meaning of any applicable federal
or state statute or the interpretation thereof or relevant common law. The Loan

its property, other than Permitted Liens, and (c) all material Indebtedness, as

appraisals of some or all of the Real Property pursuant to this Section 7.10(b)
shall be made by the Administrative Agent in good faith taking into account
applicable Laws and regulatory requirements, then existing market conditions and
such other factors as the Administrative Agent deems relevant.

all of its owned personal Property (whether now owned or leased or hereafter
acquired or leased), other than Excluded Property, to be subject at all times to
first priority, perfected and, in the case of Designated Real Property, title
insured Liens (to the extent that Liens thereon are required by this Agreement;
which title insurance shall include lender's extended coverage and shall be in
form and substance, and shall contain such endorsements, as the Collateral Agent
may require) in favor of the Collateral Agent securing the Obligations pursuant
to the terms and conditions of the Collateral Documents or, with respect to any
such Property acquired subsequent to the Closing Date, such other additional

any case to Permitted Liens, provided, however, that (i) as to any Designated
Real Property which is not owned by

<PAGE>

the Borrower or any of its Subsidiaries but which constitutes a leasehold
interest of the Borrower or any of its Subsidiaries, it shall not constitute a
Default or Event of Default if the Borrower or its Subsidiary (as applicable,
whichever is the lessee), after using its commercially reasonable efforts
(without the requirement of payment of money, except as may be agreed by the
Borrower, or the making of any material concession) to obtain any necessary
consents, is unable to grant a Lien on such leased Designated Real Property due
to the failure to obtain any third-party consents necessary to grant such Lien

Land) acquired by the Borrower or any of its Subsidiaries after the Closing
Date, the Borrower or its Subsidiary (as applicable) shall not be required to

if (but only if) (A) no Default has occurred and is continuing and (B) the fair
market value of such parcel of Real Property (inclusive of all adjoining parcels
of Real Property acquired by the Borrower or any of its Subsidiaries at or about

Property, the annual rental payable under the lease of such parcel does not
exceed $1,000,000) and the aggregate fair market value of all Designated Real
Property not subject to such a Lien does not exceed $5,000,000;

     (b)   Holdings will cause all of the Capital Stock of the Borrower owned by
Holdings (whether now owned or hereafter acquired) to be subject at all times to
Liens in favor of the Collateral Agent securing the Obligations pursuant to the
terms and conditions of the Collateral Documents or, with respect to any such
Property acquired subsequent to the Closing Date, such other additional security
documents as the Collateral Agent shall reasonably request, and at least
98.7156% of the issued and outstanding Capital Stock of the Borrower shall be so
pledged by Holdings at all times;

     (c)   The Borrower will ensure that all of the Capital Stock of the
Borrower owned by Petro and/or any other general partner of the Borrower
(whether now owned or hereafter acquired) shall be subject at all times to Liens
in favor of the Collateral Agent securing the Obligations pursuant to the terms
and conditions of the Collateral Documents or, with respect to any such Property
acquired subsequent to the Closing Date, such other additional security
documents as the Collateral Agent shall reasonably request, and

     (d)   Each Loan Party will deliver such other documentation as the
Collateral Agent may reasonably request in connection with the requirements of
this Section, including, without limitation and as applicable, appropriate UCC-1
financing statements, real estate title insurance policies, surveys,
environmental reports, estoppel letters, consents and waivers or subordinations
of landlords, certified resolutions and other organizational and authorizing
documents of such Person, and, in the case of Real Property Collateral and Liens
or any Loan Party for which such an opinion has not been previously issued and,
in either case, only if requested by the Administrative Agent, favorable
opinions of counsel to such Person (which shall cover, among other things, the
legality, validity, binding effect and enforceability of the documentation
referred to above and the perfection of the Collateral Agent's Liens thereunder)
and other items of the types required to be delivered pursuant to Section
5.01(f), all in form, content and scope reasonably satisfactory to the
Administrative Agent; provided, however, that estoppel letters, consents and
waivers or subordinations of landlords shall not be required if the Borrower or
its Subsidiary, whichever is the lessee, after using its commercially reasonable
efforts (without the requirement of payment of money, other than the except as
may be agreed by the Borrower, or the making of any material concession) to
obtain any such estoppel letters, consents and waivers or subordinations
otherwise required by this Section 7.14(d), is unable to obtain the same;

     (e)   Without limiting the generality of Section 7.14(b) or (c) above, the
Borrower and each of its Subsidiaries will cause (i) 100% of the issued and
outstanding Capital Stock of each Domestic Subsidiary and (ii) 65% (or such
greater percentage that, due to a change in an applicable Law after the date
hereof, (A) could not reasonably be expected to cause the undistributed earnings
of such Foreign

<PAGE>

Subsidiary as determined for United States federal income tax purposes to be
treated as a deemed dividend to such Foreign Subsidiary's United States parent
and (B) could not reasonably be expected to cause any material adverse tax
consequences) of the issued and outstanding Capital Stock entitled to vote
(within the meaning of Treas. Reg. Section 1.956-2(c)(2)) and 100% of the issued
and outstanding Capital Stock not entitled to vote (within the meaning of Treas.
Reg. Section 1.956-2(c)(2)) in each Foreign Subsidiary directly owned by the
Borrower or any Domestic Subsidiary to be subject at all times to a first
priority, perfected Lien in favor of the Collateral Agent pursuant to the terms
and conditions of the Collateral Documents or such other security documents as
the Collateral Agent shall reasonably request;

     (f)   Each of the Borrower and its Subsidiaries will notify the
Administrative Agent in accordance with Section 7.02(g) upon the Borrower's or
such Subsidiary's acquisition of ownership or other interests in certain types
of Properties and will execute and deliver such additional Collateral Documents
or supplements or amendments to existing Collateral Documents as the
Administrative Agent may reasonably request from time to time, together with, in
the case of any newly acquired Real Property, the additional items required to
be delivered in connection with Liens on Real Property as referred to in clause
(vi) of Section 5.01(f) in connection with Designated Real Property existing on
the Closing Date; and

     (g)   Each of the Borrower and its Subsidiaries will cause Control
Agreements, in form and substance reasonably satisfactory to the Collateral
Agent, to be executed by the appropriate Person or Persons for the purpose of
perfecting the Collateral Agent's security interests in all deposit accounts,
investment property, letter-of-credit rights and electronic chattel paper of the
Borrower and its Subsidiaries at any time in existence; provided, however, that
(i) such Control Agreements relating to deposit accounts shall not be required
to be executed to the extent the same are not required by Section 7.16 and (ii)
such Control Agreements relating to investment property, letter-of-credit rights
and electronic chattel paper shall not be required to be executed to the extent
that the aggregate amount thereof not subject to such Control Agreements does
not exceed $100,000 at any time. In connection with the exercise of its rights
under any Control Agreement, the Collateral Agent agrees with the Borrower and
its Subsidiaries that the Collateral Agent will not issue any order or make any
demand to receive the proceeds of any deposit account, investment property,
letter-of-credit right or electronic chattel paper unless and until an Event of
Default has occurred and is continuing; provided, however, that the Collateral
Agent may in its discretion, at any time during which a Default has occurred and
is continuing, issue such orders or make such demands under any Control
Agreement as it may deem necessary or appropriate to prevent any Loan Party's
disposition or expenditure of any such deposit accounts, investment property,
letter-of-credit rights and electronic chattel paper and all proceeds thereof;
provided, further, however, that the Collateral Agent shall use its reasonable
efforts to notify the Borrower of any such order issued or demand made prior to
the occurrence of an Event of Default substantially concurrently with its
issuance or making of such order or demand, respectively (but failure to do so
shall not affect the validity of any such order or demand or result in any
liability to the Collateral Agent).

     7.15  "Opt In" to Article 8. Cause the Borrower and each of its
Subsidiaries which is a limited partnership, general partnership or limited
liability company to, pursuant to its applicable Organization Documents as the
Administrative Agent may reasonably request, (a) "opt in" to Article 8 of the
UCC so that the partnership interests, membership interests or other equity
interests issued by the Borrower or such Subsidiary are treated as a security
for purposes of Articles 8 and 9 of the UCC and (b) ensure that such partnership
interests, membership interests or other equity interests issued by the Borrower
or such Subsidiary are certificated.

     7.16  Cash Management, etc. Cause all cash receipts and all payments
constituting proceeds of accounts receivable or other Collateral (other than the
Subject Receivables) to be paid, in the form received, with any appropriate
endorsements, into one or more deposit accounts with Wells Fargo or

<PAGE>

another Lender or financial institution and, without limiting the generality of
the foregoing, cause each of the Borrower's general "company" or "corporate"
accounts, other than the Borrower's cash management accounts held with Mellon
Bank, N.A. and its local or regional accounts relating to its Stopping Center
locations, to be maintained with Wells Fargo, each of which deposit accounts
shall be subject to a Control Agreement in form and substance as shall be
satisfactory to the Collateral Agent pursuant to which the Lien of the
Collateral Agent therein and in the proceeds thereof shall be perfected;
provided, however, that (a) the Borrower may, in the ordinary course of its
business and consistent with past practices, continue to deposit cash receipts,
other than the proceeds of accounts receivable, into deposit accounts held with
one or more banks if (but only if) such banks transfer the entirety of the
collected balances in each of such deposit accounts (other than reasonable
amounts deemed adequate by the Borrower in good faith to cover change orders,
returned items and bank fees, in each case associated with such account) on each
Business Day to one or more deposit accounts referred to in this Section above
which are subject to Control Agreements as referred to in this Section above,
(b) such deposit accounts held with such banks as referred to in clause (a)
preceding shall not be required to be subject to such Control Agreements if and
to the extent (but only if and to the extent) that (i) each such bank refuses to
execute such a Control Agreement notwithstanding the Borrower's commercially
reasonable and continued efforts to obtain such a Control Agreement and (ii) the
aggregate amount contained in all deposit accounts which are not subject to such
Control Agreements (exclusive of amounts pledged to or deposited with the
Administrative Agent to Cash Collateralize Letters of Credit as required by this
Agreement) shall not at any time exceed $1,000,000, and (c) any deposit account
containing only proceeds of Subject Receivables may be subject to a control
agreement in favor of Comdata or other applicable Person providing services for
the purpose of facilitating collection of the Subject Receivables on behalf and
for the account of the Borrower, in either case only to the extent required by
the Comdata Agreement.

     7.17  Further Assurances. Each of the Loan Parties will cooperate with the
Agents and the Lenders and execute such further agreements, documents and
instruments as either Agent or the Required Lenders shall reasonably request to
carry out to their satisfaction the terms and provisions of this Agreement and
the other Loan Documents and the Transactions contemplated by this Agreement and
the other Loan Documents.

     7.18  Redemption of Borrower Existing Senior Notes. The Borrower will, on
or before March 15, 2004, redeem all of the Borrower Existing Senior Notes which
were not tendered pursuant to the Borrower Existing Senior Notes Tender Offer on
or before the Closing Date (the aggregate principal amount of which notes to be
redeemed shall not exceed $20,122,000), which redemption shall be at a price not
to exceed 101.75% of the face amount thereof (the redemption price therefor set
forth in the Borrower Existing Senior Notes Indenture) plus any accrued and
unpaid interest and shall be made pursuant to the terms of the Borrower Existing
Senior Notes Indenture.

     7.19  Maintenance of Redemption Account. The Borrower will, unless and
until the Redemption occurs in accordance with Section 7.18, maintain the
Redemption Amount in the Redemption Account.

     an Involuntary Disposition which is covered by independent third-party
     insurance as to which the insurer does not dispute coverage and which does
     not constitute a default) occurs, the effect of which default or other
     event is to cause, or to permit the holder or holders of such Indebtedness
     or the beneficiary or beneficiaries of such Guarantee (or a trustee or

     (as defined in such Swap Contract) resulting from (A) any event of default
     under such Swap Contract as to which the Borrower or any Subsidiary is the
     Defaulting Party (as defined in such Swap Contract) or (B) any Termination
     Event (as so defined) under such Swap Contract as to which the Borrower or

or more final judgments or orders for the payment of money in an aggregate
amount exceeding the Threshold Amount (to the extent not covered by independent
third-party insurance as to which the insurer does not dispute coverage), or
(ii) any one or more non-monetary final judgments that have, or could reasonably
be expected to have, individually or in the aggregate, a Material Adverse Effect
and, in either case, (A) enforcement proceedings are commenced by any creditor
upon such judgment or order, or (B) there is a period of 30 consecutive days

     (l)   Loss or Damages to Collateral, etc. There occurs any material damage
to, or loss, theft or destruction of, any Collateral, or any strike, lockout,
labor dispute, embargo, condemnation, act of God or public enemy, or other
casualty, which in any such case causes, for more than 30 consecutive days, the
cessation or substantial curtailment of revenue producing activities at any
facility of the Borrower or any of its Subsidiaries if such event or
circumstance is not covered by business interruption insurance and would have a
material adverse effect on the business, assets or financial condition of the
Borrower and its Subsidiaries, taken as a whole; or

<PAGE>

     (m)   Loss, etc. of Licenses or Permits. There occurs any loss, suspension

     9.02  Remedies Upon Event of Default. If any Event of Default occurs and is

relates to any Lien or Collateral, either of the Agents may, and, at the request
of the Required Lenders, shall, take any or all of the following actions:

     (a)   declare the commitment of each Lender to make Loans and any
obligation of the L/C Issuer to make L/C Credit Extensions to be terminated,
whereupon such commitments and obligation shall be terminated;

     (b)   declare the unpaid principal amount of all outstanding Loans, all
interest accrued and unpaid thereon and all other amounts owing or payable
hereunder or under any other Loan Document to be immediately due and payable,
without presentment, demand, protest or other notice of any kind, all of which
are hereby expressly waived by each Loan Party;

     (c)   require that the Borrower Cash Collateralize the L/C Obligations (in
an amount equal to the then Outstanding Amount thereof); and

     (d)   exercise on behalf of itself and the Lenders all rights and remedies
available to it and the Lenders under the Loan Documents or applicable law;

provided, however, that upon the occurrence of an actual or deemed entry of an
order for relief with respect to any Loan Party or Petro under the Bankruptcy
Code of the United States, the obligation of each Lender to make Loans and any
obligation of the L/C Issuer to make L/C Credit Extensions shall automatically
terminate, the unpaid principal amount of all outstanding Loans and all interest
and other amounts as aforesaid shall automatically become due and payable, and
the obligation of the Borrower to Cash Collateralize the L/C Obligations as
aforesaid shall automatically become effective, in each case without further act
of either Agent or any Lender.

     9.03  Application of Funds. After the exercise of remedies provided for in
Section 9.02 (or after the Loans have automatically become immediately due and
payable and the L/C Obligations have automatically been required to be Cash
Collateralized as set forth in the proviso to Section 9.02), any amounts
received on account of the Obligations shall be applied by the Administrative
Agent in the following order:

     First, to payment of that portion of the Obligations constituting fees,
     indemnities, expenses and other amounts (including Attorney Costs and
     amounts payable under Article III) payable to the Agents or either of them
     in their or its capacity as such;

     Second, to payment of that portion of the Obligations constituting fees,
     indemnities and other amounts (other than principal and interest) payable
     to the Lenders (including Attorney Costs and

<PAGE>

     amounts payable under Article III), ratably among them in proportion to the
     amounts described in this clause Second payable to them;

     Third, to payment of that portion of the Obligations constituting accrued
     and unpaid interest on the Loans and L/C Borrowings, ratably among the
     Lenders in proportion to the respective amounts described in this clause
     Third payable to them;

     Fourth, to payment of that portion of the Obligations constituting unpaid
     principal of the Loans, L/C Borrowings and Swap Contracts and Treasury
     Management Agreements between any Loan Party and any Lender or Affiliate of
     a Lender and to Cash Collateralize that portion of L/C Obligations
     comprised of the aggregate undrawn amount of Letters of Credit, ratably
     among the Lenders in proportion to the respective amounts described in this
     clause Fourth held by them; and

     Last, the balance, if any, after all of the Obligations have been
     indefeasibly paid in full, to the Borrower or as otherwise required by Law.

Subject to Section 2.03(c), amounts used to Cash Collateralize the aggregate
undrawn amount of Letters of Credit pursuant to clause Fourth above shall be
applied to satisfy drawings under such Letters of Credit as they occur. If any
amount remains on deposit as Cash Collateral after all Letters of Credit have
either been fully drawn or expired, such remaining amount shall be applied to
the other Obligations, if any, in the order set forth above.

                                    ARTICLE X

                                     AGENTS

     10.01 Appointment and Authorization of Agents.

     (a)   Each Lender hereby irrevocably appoints, designates and authorizes
each Agent to take such action on its behalf under the provisions of this
Agreement and each other Loan Document and to exercise such powers and perform
such duties as are expressly delegated to it by the terms of this Agreement or
any other Loan Document, together with such powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary contained elsewhere
herein or in any other Loan Document, neither Agent shall have any duties or
responsibilities, except those expressly set forth herein, nor shall either
Agent have or be deemed to have any fiduciary relationship with any Lender or
participant, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or any other Loan
Document or otherwise exist against either Agent. Without limiting the
generality of the foregoing sentence, the use of the term "agent" herein and in
the other Loan Documents with reference to either Agent is not intended to
connote any fiduciary or other implied (or express) obligations arising under
agency doctrine of any applicable Law. Instead, such term is used merely as a
matter of market custom, and is intended to create or reflect only an
administrative relationship between independent contracting parties.

     (b)   The L/C Issuer shall act on behalf of the Lenders with respect to any
Letters of Credit issued by it and the documents associated therewith, and the
L/C Issuer shall have all of the benefits and immunities (i) provided to the
Administrative Agent in this Article X with respect to any acts taken or
omissions suffered by the L/C Issuer in connection with Letters of Credit issued
by it or proposed to be issued by it and the applications and agreements for
letters of credit pertaining to such Letters of Credit as fully as if the terms
"Agent", "Agents" and "Administrative Agent" as used in this Article X and in
the definition of "Agent-Related Person" included the L/C Issuer with respect to
such acts or omissions, and (ii) as additionally provided herein with respect to
the L/C Issuer.

<PAGE>

     (c)   Without limiting the generality of the foregoing, each Lender hereby
irrevocably appoints, designates and authorizes the Collateral Agent to act as
collateral agent for and on behalf of such Lender under each of the Collateral
Documents, including, without limitation, the Security Agreement.

     10.02 Delegation of Duties. Each Agent may execute any of its duties under
this Agreement or any other Loan Document by or through agents, employees or
attorneys-in-fact and shall be entitled to advice of counsel and other
consultants or experts concerning all matters pertaining to such duties. Neither
Agent shall be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects in the absence of gross negligence or willful
misconduct.

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

     10.04 Reliance by Agents.

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

     (b)   For purposes of determining compliance with the conditions specified
in Section 5.01, each Lender that has signed this Agreement shall be deemed to
have consented to, approved or accepted or to be satisfied with, each document
or other matter required thereunder to be consented to or approved by or
acceptable or satisfactory to a Lender unless the Administrative Agent shall
have received notice from such Lender prior to the proposed Closing Date
specifying its objection thereto.

<PAGE>

     10.05 Notice of Default. Neither Agent shall be deemed to have knowledge or
notice of the occurrence of any Default, except, as to the Administrative Agent
only, with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless such Agent shall have received written notice from a Lender or the
Borrower referring to this Agreement, describing such Default and stating that
such notice is a "notice of default." Each Agent will notify the Lenders of its
receipt of any such notice. Each Agent shall take such action with respect to
such Default as may be directed by the Required Lenders in accordance with
Article IX; provided, however, that unless and until such Agent has received any
such direction, such Agent may (but shall not be obligated to) take such action,
or refrain from taking such action, with respect to such Default as it shall
deem advisable or in the best interest of the Lenders.

     10.06 Credit Decision; Disclosure of Information by Agents. Each Lender
acknowledges that no Agent-Related Person has made any representation or
warranty to it, and that no act by either Agent hereafter taken, including any
consent to and acceptance of any assignment or review of the affairs of any Loan
Party or Petro or any Affiliate thereof, shall be deemed to constitute any
representation or warranty by any Agent-Related Person to any Lender as to any
matter, including whether Agent-Related Persons have disclosed material
information in their possession. Each Lender represents to each Agent that it
has, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it has deemed appropriate, made its own
appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Loan Parties
and their respective Subsidiaries and Petro, and all applicable bank or other
regulatory Laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to the Borrower
and the other Loan Parties and Petro hereunder. Each Lender also represents that
it will, independently and without reliance upon any Agent-Related Person and
based on such documents and information as it shall deem appropriate at the
time, continue to make its own credit analysis, appraisals and decisions in
taking or not taking action under this Agreement and the other Loan Documents,
and to make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and the other Loan Parties and Petro. Except
for notices, reports and other documents expressly required to be furnished to
the Lenders by the Administrative Agent herein, neither Agent shall have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of any of the Loan Parties or Petro or
any of their respective Affiliates which may come into the possession of any
Agent-Related Person.

     10.07 Indemnification of Agents. Whether or not the transactions
contemplated hereby are consummated, the Lenders shall indemnify upon demand
each Agent-Related Person (to the extent not reimbursed by or on behalf of any
Loan Party and without limiting the obligation of any Loan Party to do so), pro
rata, and hold harmless each Agent-Related Person from and against any and all
Indemnified Liabilities incurred by it; provided, however, that no Lender shall
be liable for the payment to any Agent-Related Person of any portion of such
Indemnified Liabilities to the extent determined in a final, nonappealable
judgment by a court of competent jurisdiction to have resulted from such
Agent-Related Person's own gross negligence or willful misconduct; provided,
further, however, that no action taken in accordance with the directions of the
Required Lenders shall be deemed to constitute gross negligence or willful
misconduct for purposes of this Section. Without limitation of the foregoing,
each Lender shall reimburse each Agent upon demand for its ratable share of any
costs or out-of-pocket expenses (including Attorney Costs) incurred by such
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document or any document
contemplated by or referred to herein, to the extent that such Agent is not
reimbursed for such expenses by or on behalf of the Borrower. The undertaking in
this

<PAGE>

Section shall survive termination of the Aggregate Revolving Commitments, the
payment of all other Obligations and the resignation of the Agents.

     10.08 Agents in their Individual Capacities. Wells Fargo and its Affiliates
may make loans to, issue letters of credit for the account of, accept deposits
from, acquire equity interests in and generally engage in any kind of banking,
trust, financial advisory, underwriting or other business with each of the Loan
Parties and Petro and their respective Affiliates as though Wells Fargo were not
the Administrative Agent, the Collateral Agent and the L/C Issuer hereunder and
without notice to or consent of the Lenders. The Lenders acknowledge that,
pursuant to such activities, Wells Fargo or its Affiliates may receive
information regarding any Loan Party or Petro or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Loan Party or Petro or such Affiliate) and acknowledge that neither Agent shall
be under any obligation to provide such information to them. With respect to its
Loans, Wells Fargo shall have the same rights and powers under this Agreement as
any other Lender and may exercise such rights and powers as though it were not
the Administrative Agent, the Collateral Agent and the L/C Issuer, and the terms
"Lender" and "Lenders" include Wells Fargo in its individual capacity.

     10.09 Successor Agents. Each Agent may resign as Administrative Agent or
Collateral Agent (as applicable) upon 30 days' notice to the Lenders; provided
that any such resignation by Wells Fargo shall also constitute its resignation
as L/C Issuer. If either Agent resigns under this Agreement, the Required
Lenders shall appoint from among the Lenders a successor administrative agent or
collateral agent (as applicable) for the Lenders, which successor administrative
agent or collateral agent (as applicable) shall be consented to by the Borrower
at all times other than during the existence of an Event of Default (which
consent of the Borrower shall not be unreasonably withheld, conditioned or
delayed). If no successor administrative agent or collateral agent (as
applicable) is appointed prior to the effective date of the resignation of the
Administrative Agent or Collateral Agent, respectively, the Administrative Agent
or Collateral Agent (as applicable) may appoint, after consulting with the
Lenders and the Borrower, a successor administrative agent or collateral agent,
respectively, from among the Lenders. Upon the acceptance of its appointment as
successor administrative agent or collateral agent (as applicable) hereunder,
the Person acting as such successor administrative agent or collateral agent,
respectively, shall succeed to all the rights, powers and duties of the retiring
Administrative Agent and L/C Issuer or Collateral Agent, respectively, and the
respective terms "Administrative Agent" and "L/C Issuer" or "Collateral Agent",
respectively, shall mean such successor administrative agent and Letter of
Credit issuer or collateral agent, respectively, and the retiring Administrative
Agent's or Collateral Agent's, respectively, appointment, powers and duties as
Administrative Agent or Collateral Agent, respectively, shall be terminated and
the retiring L/C Issuer's rights, powers and duties as such shall be terminated,
without any other or further act or deed on the part of such retiring L/C Issuer
or any other Lender, other than the obligation of the successor L/C Issuer to
issue letters of credit in substitution for the Letters of Credit, if any,
outstanding at the time of such succession or to make other arrangements
satisfactory to the retiring L/C Issuer to effectively assume the obligations of
the retiring L/C Issuer with respect to such Letters of Credit. After any
retiring Administrative Agent's or Collateral Agent's resignation hereunder as
Administrative Agent or Collateral Agent, respectively, the provisions of this
Article X and Sections 11.04 and 11.05 shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Administrative Agent or
Collateral Agent, respectively, under this Agreement. If no successor
administrative agent or collateral agent (as applicable) has accepted
appointment as Administrative Agent or Collateral Agent, respectively, by the
date which is 30 days following a retiring Administrative Agent's notice of
resignation, the retiring Administrative Agent's or Collateral Agent's,
respectively, resignation shall nevertheless thereupon become effective and the
Lenders shall perform all of the duties of the Administrative Agent hereunder
until such time, if any, as the Required Lenders appoint a successor agent as
provided for above.

<PAGE>

     10.10 Administrative Agent May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party or Petro, the Administrative Agent
(irrespective of whether the principal of any Loan or L/C Obligation shall then
be due and payable as herein expressed or by declaration or otherwise and
irrespective of whether the Administrative Agent shall have made any demand on
the Borrower) shall be entitled and empowered, by intervention in such
proceeding or otherwise:

     (a)   to file and prove a claim for the whole amount of the principal and
interest owing and unpaid in respect of the Loans, L/C Obligations and all other
Obligations that are owing and unpaid and to file such other documents as may be
necessary or advisable in order to have the claims of the Lenders and the Agents
(including any claim for the reasonable compensation, expenses, disbursements
and advances of the Lenders and the Agents and their respective agents and
counsel and all other amounts due the Lenders and the Agents under Sections
2.03(i) and (j), 2.09 and 11.04) allowed in such judicial proceeding; and

     (b)   to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to the Administrative Agent and, in the event
that the Administrative Agent shall consent to the making of such payments
directly to the Lenders or the Collateral Agent (as applicable), to pay to the
Administrative Agent any amount due for the reasonable compensation, expenses,
disbursements and advances of the Agents and their agents and counsel, and any
other amounts due either Agent under Sections 2.09 and 11.04.

Nothing contained herein shall be deemed to authorize any Agent to authorize or
consent to or accept or adopt on behalf of any Lender any plan of
reorganization, arrangement, adjustment or composition affecting the Obligations
or the rights of any Lender or to authorize any Agent to vote in respect of the
claim of any Lender in any such proceeding.

     10.11 Collateral and Guaranty Matters. The Lenders irrevocably authorize
the Agents, at their option and in their discretion,

     (a)   to release any Lien on any Collateral granted to or held by any Agent
under any Loan Document (i) upon termination of the Aggregate Revolving
Commitments and payment in full of all Obligations (other than contingent
indemnification obligations) and the expiration or termination of all Letters of
Credit, (ii) that is transferred or to be transferred as part of or in
connection with any Disposition permitted hereunder or under any other Loan
Document or any Involuntary Disposition, or (iii) as approved in accordance with
Section 11.01;

     (b)   to subordinate (or, if requested by the Borrower, release) any Lien
on any Property granted to or held by any Agent under any Loan Document to the
holder of any Lien on such Property that is permitted by Section 8.01(b) or (i);
and

     (c)   to release any Guarantor from its obligations under the Guaranty if
such Person ceases to be a Subsidiary as a result of a transaction permitted
hereunder.

Upon request by either Agent at any time, the Required Lenders will confirm in
writing such Agent's authority to release or subordinate its interest in
particular types or items of Property, or to release any Guarantor from its
obligations under the Guaranty, pursuant to this Section 10.11.

<PAGE>

     10.12 Other Agents; Arrangers and Managers. None of the Lenders or other
Persons identified on the facing page or signature pages of this Agreement as a
"syndication agent," "documentation agent," "co-agent," "book manager," "lead
manager," "arranger," "lead arranger" or "co-arranger" shall have any right,
power, obligation, liability, responsibility or duty under this Agreement other
than, in the case of such Lenders, those applicable to all Lenders as such.
Without limiting the foregoing, none of the Lenders or other Persons so
identified shall have or be deemed to have any fiduciary relationship with any
Lender. Each Lender acknowledges that it has not relied, and will not rely, on
any of the Lenders or other Persons so identified in deciding to enter into this
Agreement or in taking or not taking action hereunder.

     10.13 Delivery of Financial Statements and Certain Other Information to the
Lenders. The Administrative Agent shall deliver to each Lender, in a reasonably
prompt fashion after the Administrative Agent receives such financial statements
or other information from the Borrower, a true and correct copy of (a) all
financial statements delivered to the Administrative Agent pursuant to Section
7.01 and (b) all information delivered to the Administrative Agent pursuant to
Section 7.02 or 7.03, all of which may be delivered to the Lenders by electronic
mail or internet or intranet websites or in such other manner as the
Administrative Agent may desire.

                                  MISCELLANEOUS

     11.01 Amendments, Etc. No amendment or waiver of any provision of this
Agreement or any other Loan Document, and no consent to any departure by the
Borrower or any other Loan Party or Petro therefrom, shall be effective unless
in writing signed by the Required Lenders and the Borrower or the applicable
Loan Party or Petro, as the case may be, and acknowledged by the Agents, and
each such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given; provided, however, that no such
amendment, waiver or consent shall:

     (a)   waive any condition set forth in Section 5.01(a) without the written
consent of each Lender, except as may be agreed to by the Agents in connection
with any post-closing agreement which has been disclosed or delivered to the
Lenders;

     (b)   extend or increase the Commitment of any Lender (or reinstate any
Commitment terminated pursuant to Section 9.02) without the written consent of
such Lender (it being understood and agreed that a waiver of any condition
precedent set forth in Section 5.02 or of any Default or Event of Default or a
mandatory reduction in Commitments is not considered an extension or increase in
Commitments of any Lender);

     (c)   postpone any date fixed by this Agreement or any other Loan Document
for any payment of principal (including mandatory prepayments required by
Section 2.05), interest, fees or other amounts due to the Lenders (or any of
them) hereunder or under any other Loan Document without the written consent of
each Lender directly affected thereby;

     (d)   reduce the principal of, or the rate of interest specified herein on,
any Loan or L/C Borrowing, or any fees or other amounts payable hereunder or
under any other Loan Document without the written consent of each Lender

pro rata sharing of payments required thereby without the written consent of
each Lender directly affected thereby;

<PAGE>

     (f)   change any provision of this Section or the definition of "Required
Lenders" or any other provision hereof specifying the number or percentage of
Lenders required to amend, waive or otherwise modify any rights hereunder or
make any determination or grant any consent hereunder without the written
consent of each Lender;

     (g)   except in connection with a Disposition permitted under Section 8.05,
release all or any material portion of the Collateral without the written
consent of each Lender; or

     (h)   release the Borrower or, except in connection with a merger or
consolidation permitted under Section 8.04 or a Disposition permitted under
Section 8.05, any of the Guarantors from its or their obligations under the Loan
Documents without the written consent of each Lender;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the L/C Issuer in addition to the Lenders required above,
affect the rights or duties of the L/C Issuer under this Agreement or any Letter
of Credit Application relating to any Letter of Credit issued or to be issued by
it; (ii) no amendment, waiver or consent shall, unless in writing and signed by
such Agent in addition to the Lenders required above, affect the rights or
duties of either Agent under this Agreement or any other Loan Document; and
(iii) any Fee Letter may be amended, or rights or privileges thereunder waived,
in a writing executed only by the parties thereto. Notwithstanding anything to
the contrary herein, no Defaulting Lender shall have any right to approve or
disapprove any amendment, waiver or consent hereunder, except that the
Commitment of such Lender may not be increased or extended without the consent
of such Lender.

Notwithstanding the fact that the consent of all the Lenders is required in
certain circumstances as set forth above, (A) each Lender is entitled to vote as
such Lender sees fit on any bankruptcy reorganization plan that affects the
Loans, and each Lender acknowledges that the provisions of Section 1126(c) of
the Bankruptcy Code supersedes the unanimous consent provisions set forth herein
and (B) the Required Lenders shall determine whether or not to allow a Loan
Party or Petro to use cash collateral in the context of a bankruptcy or
insolvency proceeding and such determination shall be binding on all of the
Lenders.

     11.02 Notices and Other Communications; Facsimile Copies.

     (a)   General. Unless otherwise expressly provided herein, all notices and
other communications provided for hereunder shall be in writing (including by
facsimile transmission). All such written notices shall be mailed certified or
registered mail, faxed or delivered to the applicable address, facsimile number
or (subject to subsection (c) below) electronic mail address, and all notices
and other communications expressly permitted hereunder to be given by telephone
shall be made to the applicable telephone number, as follows:

          (i)   if to any Loan Party or Petro, the Administrative Agent, the
     Collateral Agent or the L/C Issuer, to the address, facsimile number,
     electronic mail address or telephone number specified for such Person on
     Schedule 11.02 or to such other address, facsimile number, electronic mail
     address or telephone number as shall be designated by such party in a
     notice to the other parties; and

          (ii)  if to any other Lender, to the address, facsimile number,
     electronic mail address or telephone number specified in its Administrative
     Questionnaire or to such other address, facsimile number, electronic mail
     address or telephone number as shall be designated by such party in a
     notice to the Borrower, the Administrative Agent, the Collateral Agent and
     the L/C Issuer.

<PAGE>

All such notices and other communications shall be deemed to be given or made
upon the earlier to occur of (i) actual receipt by the relevant party hereto and
(ii) (A) if delivered by hand or by courier, when signed for by or on behalf of
the relevant party hereto; (B) if delivered by mail, four Business Days after
deposit in the mails, postage prepaid; (C) if delivered by facsimile, when sent
and receipt has been confirmed by telephone; and (D) if delivered by electronic
mail (which form of delivery is subject to the provisions of subsection (c)
below), when delivered; provided, however, that notices and other communications
to either Agent and the L/C Issuer pursuant to Article II shall not be effective
until actually received by such Person as set forth above. In no event shall a
voicemail message be effective as a notice, communication or confirmation
hereunder.

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

     (c)   Limited Use of Electronic Mail. Electronic mail and internet and
intranet websites may be used only to distribute routine communications, such as
financial statements and other information as provided in Sections 7.01 and
7.02, and to distribute Loan Documents for execution by the parties thereto, and
may not be used for any other purpose.

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

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

     11.04 Attorney Costs, Expenses and Taxes. The Borrower agrees (a) to pay or
reimburse each Agent for all costs and expenses incurred in connection with the
development, preparation, negotiation and execution of this Agreement and the
other Loan Documents and any amendment, waiver, consent or other modification of
the provisions hereof and thereof (whether or not the transactions contemplated
hereby or thereby are consummated), and the consummation and administration of
the transactions contemplated hereby and thereby, including all Attorney Costs
and costs and expenses in connection with the use of Intralinks, Inc. or other
similar information transmission systems in connection with this Agreement, and
(b) to pay or reimburse each Agent and each Lender for all costs and expenses
incurred in connection with the enforcement, attempted enforcement or
preservation of any rights or

<PAGE>

remedies under this Agreement or the other Loan Documents (including all such
costs and expenses incurred during any "workout" or restructuring in respect of
the Obligations and during any legal proceeding, including any proceeding under
any Debtor Relief Law), including all Attorney Costs. The foregoing costs and
expenses shall include all search, filing, recording, title insurance and
appraisal charges and fees and taxes related thereto, and other out-of-pocket
expenses incurred by either Agent and the cost of independent public accountants
and other outside experts retained by either Agent or any Lender. All amounts
due under this Section 11.04 shall be payable within ten Business Days after
demand therefor. The agreements in this Section shall survive the termination of
the Aggregate Revolving Commitments and repayment of all other Obligations.

     11.05 Indemnification by the Borrower. Whether or not the transactions
contemplated hereby are consummated, the Borrower agrees to indemnify and hold
harmless each Agent-Related Person, each Lender and their respective Affiliates,
directors, officers, employees, counsel, agents and attorneys-in-fact
(collectively the "Indemnitees") from and against any and all liabilities,
obligations, losses, damages, penalties, claims, demands, actions, judgments,
suits, costs, expenses and disbursements (including Attorney Costs) of any kind
or nature whatsoever which may at any time be imposed on, incurred by or
asserted against any such Indemnitee in any way relating to or arising out of or
in connection with (a) the execution, delivery, enforcement, performance or
administration of any Loan Document or any other agreement, letter or instrument
delivered in connection with the transactions contemplated thereby or the
consummation of the transactions contemplated thereby, (b) any Commitment, Loan
or Letter of Credit or the use or proposed use of the proceeds therefrom
(including any refusal by the L/C Issuer to honor a demand for payment under a
Letter of Credit if the documents presented in connection with such demand do
not strictly comply with the terms of such Letter of Credit), (c) any actual or
alleged presence or release of Hazardous Materials on or from any Property
currently or formerly owned or operated by the Borrower, any Subsidiary or any
other Loan Party, or any Environmental Liability related in any way to the
Borrower, any Subsidiary or any other Loan Party, or (d) any actual or
prospective claim, litigation, investigation or proceeding relating to any of
the foregoing, whether based on contract, tort or any other theory (including
any investigation of, preparation for or defense of any pending or threatened
claim, investigation, litigation or proceeding) and regardless of whether any
Indemnitee is a party thereto (all the foregoing, collectively, the "Indemnified
Liabilities"), in all cases, whether or not caused by or arising, in whole or in
part, out of the negligence of the Indemnitee; provided that such indemnity
shall not, as to any Indemnitee, be available to the extent that such
liabilities, obligations, losses, damages, penalties, claims, demands, actions,
judgments, suits, costs, expenses or disbursements are determined by a court of
competent jurisdiction by final and nonappealable judgment to have resulted from
the gross negligence or willful misconduct of such Indemnitee. No Indemnitee
shall be liable for any damages arising from the use by others of any
information or other materials obtained through IntraLinks or other similar
information transmission systems in connection with this Agreement, nor shall
any Indemnitee have any liability for any indirect or consequential damages
relating to this Agreement or any other Loan Document or arising out of its
activities in connection herewith or therewith (whether before or after the
Closing Date). All amounts due under this Section 11.05 shall be payable within
ten Business Days after demand therefor. The agreements in this Section shall
survive the resignation of the Agents, the replacement of any Lender, the
termination of the Aggregate Revolving Commitments and the repayment,
satisfaction or discharge of all the other Obligations.

     11.06 Payments Set Aside. To the extent that any payment by or on behalf of
any Loan Party or Petro is made to either Agent or any Lender, or either Agent
or any Lender exercises its right of set-off, and such payment or the proceeds
of such set-off or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by either Agent or such Lender in its discretion) to be
repaid to a trustee, receiver or any other party, in connection with any
proceeding under any Debtor Relief Law or otherwise, then (a) to the extent of
such

<PAGE>

recovery, the obligation or part thereof originally intended to be satisfied
shall be revived and continued in full force and effect as if such payment had
not been made or such set-off had not occurred, and (b) each Lender severally
agrees to pay to each Agent upon demand its applicable share of any amount so
recovered from or repaid by such Agent, plus interest thereon from the date of
such demand to the date such payment is made at a rate per annum equal to the
Federal Funds Rate from time to time in effect.

     11.07 Successors and Assigns.

     (a)   The provisions of this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that neither the Borrower nor any other Loan Party nor
Petro may assign or otherwise transfer any of its rights or obligations
hereunder without the prior written consent of each Lender and no Lender may
assign or otherwise transfer any of its rights or obligations hereunder except
(i) to an Eligible Assignee in accordance with the provisions of subsection (b)
of this Section, (ii) by way of participation in accordance with the provisions
of subsection (d) of this Section or (iii) by way of pledge or assignment of a
security interest subject to the restrictions of subsection (f) of this Section
(and any other attempted assignment or transfer by any party hereto shall be
null and void). Nothing in this Agreement, expressed or implied, shall be
construed to confer upon any Person (other than the parties hereto, their
respective successors and assigns permitted hereby, Participants to the extent
provided in subsection (d) of this Section and, to the extent expressly
contemplated hereby, the Indemnitees) any legal or equitable right, remedy or
claim under or by reason of this Agreement.

     (b)   Any Lender may at any time assign to one or more Eligible Assignees
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment and the Loans (including, for purposes of
this subsection (b), participations in L/C Obligations) at the time owing to
it); provided that (i) except in the case of an assignment of the entire
remaining amount of the assigning Lender's Commitment and the Loans at the time
owing to it or in the case of an assignment to a Lender or an Affiliate of a
Lender or an Approved Fund (as defined in subsection (g) of this Section) with
respect to a Lender, the aggregate amount of the Commitment (which for this
purpose includes Loans outstanding thereunder) subject to each such assignment,
determined as of the date the Assignment and Assumption with respect to such
assignment is delivered to the Administrative Agent or, if "Trade Date" is
specified in the Assignment and Assumption, as of the Trade Date, shall not be
less than $1,000,000, in the case of any assignment in respect of the Revolving
Loans and/or any Revolving Commitment, or $1,000,000, in the case of any
assignment in respect of the Term Loan, unless each of the Administrative Agent
and, so long as no Event of Default has occurred and is continuing, the Borrower
otherwise consents (each such consent not to be unreasonably withheld or
delayed); (ii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement with respect to the Loans or the Commitment assigned, except that
this clause (ii) shall not prohibit any Lender from assigning all or a portion
of its rights and obligations among separate tranches on a non-pro rata basis;
(iii) any assignment of a Revolving Commitment must be approved by the
Administrative Agent and the L/C Issuer unless the Person that is the proposed
assignee is itself a Lender with a Revolving Commitment (whether or not the
proposed assignee would otherwise qualify as an Eligible Assignee); and (iv) the
parties to each assignment shall execute and deliver to the Administrative Agent
an Assignment and Assumption, together with a processing and recordation fee of
$3,500 (which fee is not payable by the Borrower). Subject to acceptance and
recording thereof by the Administrative Agent pursuant to subsection (c) of this
Section, from and after the effective date specified in each Assignment and
Assumption, the Eligible Assignee thereunder shall be a party to this Agreement
and, to the extent of the interest assigned by such Assignment and Assumption,
have the rights and obligations of a Lender under this Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by
such Assignment and Assumption, be released from its obligations under this
Agreement (and, in the case of an Assignment and Assumption covering all of the
assigning Lender's rights and

<PAGE>

obligations under this Agreement, such Lender shall cease to be a party hereto
but shall continue to be entitled to the benefits of Sections 3.01, 3.04, 3.05,
11.04 and 11.05 with respect to facts and circumstances occurring prior to the
effective date of such assignment). Upon request, the Borrower (at its expense)
shall execute and deliver a Note to the assignee Lender. Any assignment or
transfer by a Lender of rights or obligations under this Agreement that does not
comply with this subsection (b) shall be treated for purposes of this Agreement
as a sale by such Lender of a participation in such rights and obligations in
accordance with subsection (d) of this Section.

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

     (d)   Any Lender may at any time, without the consent of, or notice to, the
Borrower or either Agent, sell participations to any Person (other than a
natural person or the Borrower or any of the Borrower's Affiliates or
Subsidiaries) (each, a "Participant") in all or a portion of such Lender's
rights and/or obligations under this Agreement (including all or a portion of
its Commitment and/or the Loans (including such Lender's participations in L/C
Obligations) owing to it); provided that (i) such Lender's obligations under
this Agreement shall remain unchanged, (ii) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (iii) the Borrower, the Agents and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, waiver or other modification
described in the first proviso to Section 11.01 that directly affects such
Participant. Subject to subsection (e) of this Section, the Borrower agrees that
each Participant shall be entitled to the benefits of Sections 3.01, 3.04 and
3.05 to the same extent as if it were a Lender and had acquired its interest by
assignment pursuant to subsection (b) of this Section. To the extent permitted
by law, each Participant also shall be entitled to the benefits of Section 11.09
as though it were a Lender, provided such Participant agrees to be subject to
Section 2.13 as though it were a Lender.

     (e)   A Participant shall not be entitled to receive any greater payment
under Section 3.01 or 3.04 than the applicable Lender would have been entitled
to receive with respect to the participation sold to such Participant. A
Participant that would be a Foreign Lender if it were a Lender shall not be
entitled to the benefits of Section 3.01 unless the Borrower is notified of the
participation sold to such Participant and such Participant agrees, for the
benefit of the Borrower, to comply with Section 11.15 as though it were a
Lender.

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

<PAGE>

     (g)   As used herein, the following terms have the following meanings:

           "Eligible Assignee" means (a) a Lender; (b) an Affiliate of a Lender;
     (c) an Approved Fund; and (d) any other Person (other than a natural
     person) approved by (i) the Administrative Agent and the L/C Issuer, and
     (ii) unless an Event of Default has occurred and is continuing, the
     Borrower (each such approval not to be unreasonably withheld or delayed);
     provided that notwithstanding the foregoing, "Eligible Assignee" shall not
     include the Borrower or any of the Borrower's Affiliates or Subsidiaries.

           "Fund" means any Person (other than a natural person) that is (or
     will be) engaged in making, purchasing, holding or otherwise investing in
     commercial loans and similar extensions of credit in the ordinary course of
     its business.

           "Approved Fund" means any Fund that is administered or managed by (a)
     a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of
     an entity that administers or manages a Lender.

     (h)   Notwithstanding anything to the contrary contained herein, if at any
time Wells Fargo assigns all of its Commitment and Loans pursuant to subsection
(b) above, Wells Fargo may, upon 30 days' notice to the Borrower and the
Lenders, resign as L/C Issuer. In the event of any such resignation as L/C
Issuer, the Borrower shall be entitled to appoint from among the Lenders a
successor L/C Issuer hereunder; provided, however, that no failure by the
Borrower to appoint any such successor shall affect the resignation of Wells
Fargo as L/C Issuer. If Wells Fargo resigns as L/C Issuer, it shall retain all
the rights and obligations of the L/C Issuer hereunder with respect to all
Letters of Credit outstanding as of the effective date of its resignation as L/C
Issuer and all L/C Obligations with respect thereto (including the right to
require the Lenders to make Base Rate Loans or fund risk participations in
Unreimbursed Amounts pursuant to Section 2.03(c)).

     11.08 Confidentiality. Each of the Agents and the Lenders agrees to
maintain the confidentiality of the Information (as defined below), except that
Information may be disclosed (a) to its and its Affiliates' partners, directors,
officers, employees and agents, including accountants, legal counsel and other
advisors and representatives (it being understood that the Persons to whom such
disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential); (b) to the
extent requested by any regulatory authority purporting to have jurisdiction
over it; (c) to the extent required by applicable laws or regulations or by any
subpoena or similar legal process; (d) to any other party to this Agreement; (e)
in connection with the exercise of any remedies hereunder or under any other
Loan Document or any suit, action or proceeding relating to this Agreement or
any other Loan Document or the enforcement of rights hereunder or thereunder;
(f) subject to an agreement containing provisions substantially the same as
those of this Section, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any direct or indirect contractual counterparty or
prospective counterparty (or such contractual counterparty's or prospective
counterparty's professional advisor) to any credit derivative transaction
relating to obligations of any Loan Party or Petro; (g) with the consent of the
Borrower; (h) to the extent such Information (i) becomes publicly available
other than as a result of a breach of this Section or (ii) becomes available to
either Agent or any Lender on a nonconfidential basis from a source other than
the Borrower; or (i) to the National Association of Insurance Commissioners or
any other similar organization or any nationally recognized rating agency that
requires access to information about a Lender's or its Affiliates' investment
portfolio in connection with ratings issued with respect to such Lender or its
Affiliates (provided that the identity of any Loan Party or Guarantor or
information that would identify any Loan Party or Guarantor may not be disclosed
pursuant to this clause (i)). In addition, the Agents and the Lenders may
disclose the existence of this Agreement and information about this

<PAGE>

Agreement (but not the identity of any Loan Party or Guarantor or information
that would identify any Loan Party or Guarantor) to market data collectors,
similar service providers to the lending industry and service providers to the
Agents and the Lenders in connection with the administration and management of
this Agreement, the other Loan Documents, the Commitments and the Credit
Extensions.

For the purposes of this Section, "Information" means all information received
from any Loan Party relating to any Loan Party or its business, other than any
such information that is available to either Agent or any Lender on a
nonconfidential basis prior to disclosure by any Loan Party; provided that, in
the case of information received from a Loan Party after the date hereof, such
information is clearly identified in writing at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information
as provided in this Section shall be considered to have complied with its
obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to
its own confidential information. Notwithstanding anything herein to the
contrary, "Information" shall not include, and the Borrower, the other Loan
Parties, each Agent, each Lender and the respective Affiliates of each of the
foregoing (and the respective partners, directors, officers, employees, agents,
advisors and other representatives of each of the foregoing and their
Affiliates) may disclose to any and all Persons, without limitation of any kind
(i) any information with respect to the U.S. federal and state income tax
treatment of the transactions contemplated hereby and any facts that may be
relevant to understanding such tax treatment, which facts shall not include for
this purpose the names of the parties or any other Person named herein, or
information that would permit identification of the parties or such other
Persons, or any pricing terms or other nonpublic business or financial
information that is unrelated to such tax treatment or facts, and (ii) all
materials of any kind (including opinions or other tax analyses) relating to
such tax treatment or facts that are provided to any of the Persons referred to
above.

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

     11.10 Interest Rate Limitation.

     (a)   Notwithstanding anything to the contrary contained in this Agreement
or any other Loan Document, no interest rate specified in this Agreement or any
other Loan Document or paid or agreed to be paid pursuant to this Agreement or
any other Loan Document shall at any time exceed the Maximum Rate. If at any
time the interest rate otherwise (but for the terms and provisions of this
Section 11.10) contracted for in this Agreement or any other Loan Document (the
"Contract Rate") for any Obligation shall exceed the Maximum Rate, thereby
causing the interest accruing on such Obligation to be limited to the Maximum
Rate, then any subsequent reduction in the Contract Rate for such Obligation
shall not reduce the rate of interest on such Obligation below the Maximum Rate
until the aggregate amount of

<PAGE>

interest accrued on such Obligation equals the aggregate amount of interest
which would have accrued on such Obligation if the Contract Rate for such
Obligation had at all times been in effect.

     (b)   Notwithstanding anything to the contrary contained in this Agreement
or any other Loan Document, none of the terms and provisions of this Agreement
or any other Loan Documents shall ever be construed to create a contract or
obligation to pay interest at a rate in excess of the Maximum Rate; and neither
either Agent nor any Lender shall ever charge, receive, take, collect, reserve
or apply, as interest on the Obligations, any amount in excess of the Maximum
Rate. The parties hereto agree that any interest, charge, fee, expense or other
obligation provided for in this Agreement or in the other Loan Documents which
constitutes interest under applicable law shall be, ipso facto and under any and
all circumstances, limited or reduced to an amount equal to the lesser of (i)
the amount of such interest, charge, fee, expense or other obligation that would
be payable in the absence of this Section 11.10(b) or (ii) an amount which, when
added to all other interest payable under this Agreement and the other Loan
Documents, equals the Maximum Rate. If, notwithstanding the foregoing, either
Agent or any Lender ever contracts for, charges, receives, takes, collects,
reserves or applies as interest any amount in excess of the Maximum Rate, such
amount which would be deemed excessive interest shall be deemed a partial
payment or prepayment of principal of the Obligations and treated hereunder as
such; and if the Obligations, or applicable portions thereof, are paid in full,
any remaining excess shall promptly be paid to the Borrower or other appropriate
Loan Party or Petro. In determining whether the interest paid or payable, under
any specific contingency, exceeds the Maximum Rate, the Borrower, the Agents and
the Lenders shall, to the maximum extent permitted by applicable law, (A)
characterize any nonprincipal payment as an expense, fee or premium rather than
as interest, (B) exclude voluntary prepayments and the effects thereof, and (C)
amortize, prorate, allocate and spread in equal or unequal parts the total
amount of interest throughout the entire contemplated term of the Obligations,
or applicable portions thereof, so that the interest rate does not exceed the
Maximum Rate at any time during the term of the Obligations; provided that, if
the unpaid principal balance is paid and performed in full prior to the end of
the full contemplated term thereof, and if the interest received for the actual
period of existence thereof exceeds the Maximum Rate, the Agents and/or the
Lenders, as appropriate, shall refund to the Borrower or other appropriate Loan
Party or Petro the amount of such excess and, in such event, the Agents and the
Lenders shall not be subject to any penalties provided by any laws for
contracting for, charging, receiving, taking, collecting, reserving or applying
interest in excess of the Maximum Rate.

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

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

     11.13 Survival of Representations and Warranties. All representations and
warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by each Agent
and each Lender, regardless of any investigation made by either Agent or any
Lender or on their behalf and notwithstanding that either Agent or any Lender
may have had notice or knowledge of any Default at the time of any

<PAGE>

Credit Extension, and shall continue in full force and effect as long as any
Loan or any other Obligation hereunder shall remain unpaid or unsatisfied or any
Letter of Credit shall remain outstanding.

     11.14 Severability. If any provision of this Agreement or the other Loan
Documents is held to be illegal, invalid or unenforceable, (a) the legality,
validity and enforceability of the remaining provisions of this Agreement and
the other Loan Documents shall not be affected or impaired thereby and (b) the
parties shall endeavor in good faith negotiations to replace the illegal,
invalid or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

     11.15 Tax Forms.

     (a)   (i)   Each Lender that is not a "United States person" within the
     meaning of Section 7701(a)(30) of the Internal Revenue Code (a "Foreign
     Lender") shall deliver to the Administrative Agent, prior to receipt of any
     payment subject to withholding under the Internal Revenue Code (or upon
     accepting an assignment of an interest herein), two duly signed completed
     copies of either IRS Form W-8BEN or any successor thereto (relating to such
     Foreign Lender and entitling it to an exemption from, or reduction to zero
     of, withholding tax on all payments to be made to such Foreign Lender by
     the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any
     successor thereto (relating to all payments to be made to such Foreign
     Lender by the Borrower pursuant to this Agreement) or such other evidence
     satisfactory to the Borrower and the Administrative Agent that such Foreign
     Lender is entitled to an exemption from, or reduction to zero of, U.S.
     withholding tax, including any exemption pursuant to Section 881(c) of the
     Internal Revenue Code. Thereafter and from time to time, each such Foreign
     Lender shall (A) promptly submit to the Administrative Agent such
     additional duly completed and signed copies of one of such forms (or such
     successor forms as shall be adopted from time to time by the relevant
     United States taxing authorities) as may then be available under then
     current United States laws and regulations to avoid, or such evidence as is
     satisfactory to the Borrower and the Administrative Agent of any available
     exemption from or reduction of, United States withholding taxes in respect
     of all payments to be made to such Foreign Lender by the Borrower pursuant
     to this Agreement, (B) promptly notify the Administrative Agent of any
     change in circumstances which would modify or render invalid any claimed
     exemption or reduction, and (C) take such steps as shall not be materially
     disadvantageous to it, in the reasonable judgment of such Lender, and as
     may be reasonably necessary (including the re-designation of its Lending
     Office) to avoid any requirement of applicable Laws that the Borrower make
     any deduction or withholding for taxes from amounts payable to such Foreign
     Lender.

           (ii)  Each Foreign Lender, to the extent it does not act or ceases to
     act for its own account with respect to any portion of any sums paid or
     payable to such Lender under any of the Loan Documents (for example, in the
     case of a typical participation by such Lender), shall deliver to the
     Administrative Agent on the date when such Foreign Lender ceases to act for
     its own account with respect to any portion of any such sums paid or
     payable, and at such other times as may be necessary in the determination
     of the Administrative Agent (in the reasonable exercise of its discretion),
     (A) two duly signed completed copies of the forms or statements required to
     be provided by such Lender as set forth above, to establish the portion of
     any such sums paid or payable with respect to which such Lender acts for
     its own account that is not subject to U.S. withholding tax, and (B) two
     duly signed completed copies of IRS Form W-8IMY (or any successor thereto),
     together with any information such Lender chooses to transmit with such
     form, and any other certificate or statement of exemption required under
     the Internal Revenue

<PAGE>

     Code, to establish that such Lender is not acting for its own account with
     respect to a portion of any such sums payable to such Lender.

           (iii) The Borrower shall not be required to pay any additional amount
     to any Foreign Lender under Section 3.01 (A) with respect to any Taxes
     required to be deducted or withheld on the basis of the information,
     certificates or statements of exemption such Lender transmits with an IRS
     Form W-8IMY pursuant to this Section 11.15(a) or (B) if such Lender shall
     have failed to satisfy the foregoing provisions of this Section 11.15(a);
     provided that if such Lender shall have satisfied the requirement of this
     Section 11.15(a) on the date such Lender became a Lender or ceased to act
     for its own account with respect to any payment under any of the Loan
     Documents, nothing in this Section 11.15(a) shall relieve the Borrower of
     its obligation to pay any amounts pursuant to Section 3.01 in the event
     that, as a result of any change in any applicable law, treaty or
     governmental rule, regulation or order, or any change in the
     interpretation, administration or application thereof, such Lender is no
     longer properly entitled to deliver forms, certificates or other evidence
     at a subsequent date establishing the fact that such Lender or other Person
     for the account of which such Lender receives any sums payable under any of
     the Loan Documents is not subject to withholding or is subject to
     withholding at a reduced rate.

           (iv)  Each Agent may, without reduction, withhold any Taxes required
     to be deducted and withheld from any payment under any of the Loan
     Documents with respect to which the Borrower is not required to pay
     additional amounts under this Section 11.15(a).

     (b)   Upon the request of the Administrative Agent, each Lender that is a
"United States person" within the meaning of Section 7701(a)(30) of the Internal
Revenue Code shall deliver to the Administrative Agent two duly signed completed
copies of IRS Form W-9. If such Lender fails to deliver such forms, then the
Administrative Agent may withhold from any interest payment to such Lender an
amount equivalent to the applicable back-up withholding tax imposed by the
Internal Revenue Code, without reduction.

     (c)   If any Governmental Authority asserts that either Agent did not
properly withhold or backup withhold, as the case may be, any tax or other
amount from payments made to or for the account of any Lender, such Lender shall
indemnify such Agent therefor, including all penalties and interest, any taxes
imposed by any jurisdiction on the amounts payable to such Agent under this
Section, and costs and expenses (including Attorney Costs) of such Agent. The
obligation of the Lenders under this Section shall survive the termination of
the Aggregate Revolving Commitments, repayment of all other Obligations
hereunder and the resignation of the Agents.

     11.16 Replacement of Lenders. Under any circumstances set forth herein
providing that the Borrower shall have the right to replace a Lender as a party
to this Agreement, the Borrower may, upon notice to such Lender and the
Administrative Agent, replace such Lender by causing such Lender to assign its
Commitments and outstanding Loans (with the assignment fee to be paid by the
Borrower in such instance) pursuant to Section 11.07(b) to one or more other
Lenders or Eligible Assignees procured by the Borrower; provided, however, that
if the Borrower elects to exercise such right with respect to any Lender
pursuant to Section 3.06(b), it shall be obligated to replace all Lenders that
have made similar requests for compensation pursuant to Section 3.01 or 3.04.
Upon the making of any such assignment, the Borrower shall (a) pay in full all
principal, interest, fees and other amounts owing to such Lender through the
date of replacement (including any amounts payable pursuant to Section 3.05),
(b) provide appropriate assurances and indemnities (which may include letters of
credit) to the L/C Issuer as such Lender may reasonably require with respect to
any continuing obligation to fund participation interests in any L/C Obligations
then outstanding, and (c) release such Lender from its obligations under the
Loan

<PAGE>

Documents. Any Lender being replaced shall execute and deliver an Assignment and
Assumption with respect to such Lender's Commitment and outstanding Loans and
participations in L/C Obligations.
