      Borrower, Toronto Dominion (Texas), Inc., as administrative agent (the
"Prior Administrative Agent"), The Toronto-Dominion Bank, as issuing bank, and
certain lenders party thereto (the "Prior Lenders") have heretofore entered into
a Credit Agreement dated as of December 17, 2001, as amended, modified or
supplemented (the "Existing Credit Facility").

      Borrower desires to amend and restate the Existing Credit Facility in
order to restructure, rearrange, renew, extend and continue all indebtedness
evidenced by and outstanding under the Existing Credit Facility (the "Existing
Indebtedness"), and to modify the commitments from the Lenders pursuant to which
Loans will be made by the Lenders to the Borrower from time to time prior to the
Maturity Date and Letters of Credit will be issued by the Issuing Bank under the
several responsibilities of the Lenders for the account of the Borrower from
time to time prior to the Letter of Credit Availability Expiration Date.

      Borrower has delivered to Prior Administrative Agent certain collateral
documents to secure the repayment of the Existing Indebtedness to the Prior
Lenders, which collateral documents are being assigned to the Administrative
Agent in connection with, and concurrently with, the restructuring,
rearrangement, renewal, extension and continuation of the Existing Indebtedness
pursuant to this Agreement.

      The Administrative Agent, the Lenders and the Issuing Bank are willing, on
the terms and subject to the conditions hereinafter set forth (including Article
IV), to amend and restate the Existing Credit Facility in order to restructure,
rearrange, renew, extend and continue all Existing Indebtedness and to modify
the commitments and make such Loans to the Borrower and issue and participate in
such Letters of Credit for the account of the Borrower.

      It is in the best interest of each of the Guarantors to execute and
deliver a Guaranty as each Guarantor will receive substantial benefits as a
result of the Borrower entering into the borrowing base, revolving credit
facility with the Lenders.

                      THE COMMITMENTS AND CREDIT EXTENSIONS

      SECTION 2.1 LOANS. Subject to the terms and conditions set forth herein,
each Lender severally agrees to make loans (each such loan, a "Loan") to the
Borrower from time to time on any Business Day during the period from the
Closing Date to the Maturity Date, in an aggregate amount not to exceed at any
time outstanding the lesser of (x) such Lender's Percentage Share of the

                                       20
<PAGE>

aggregate amount of the Loans requested by the Borrower on such day and (y) the
amount of such Lender's Commitment; provided, however, that after giving effect
to any borrowing, (i) the aggregate Outstanding Amount of all Loans and L/C
Obligations shall not exceed the lesser of (A) the Aggregate Commitments on such
date and (B) the Borrowing Base then in effect minus the aggregate principal
amount of all 1999 Senior Notes then outstanding, and (ii) the aggregate
Outstanding Amount of the Loans of any Lender, plus such Lender's Percentage
Share of the Outstanding Amount of all L/C Obligations shall not exceed such
Lender's Commitment or such Lender's Percentage Share of (x) the Borrowing Base
minus (y) the aggregate principal amount of all 1999 Senior Notes then
outstanding. Within the limits of each Lender's Commitment, and subject to the
other terms and conditions hereof, the Borrower may borrow under this Section
2.1, prepay under Section 2.4 and reborrow under this Section 2.1.

      SECTION 2.2 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

      (a) Each Borrowing, each conversion of Loans from one Type to the other,
and each continuation of Loans as the same Type shall be made upon the
Borrower's irrevocable prior written notice to the Administrative Agent in the
form of a Notice of Advance. Each such notice must be received by the
Administrative Agent not later than 12:00 p.m., central time, (i) three Business
Days prior to the requested date of any Borrowing of, conversion to or
continuation of LIBO Rate Loans or of any conversion of LIBO Rate Loans to Base
Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans.
Each Notice of Advance shall be appropriately completed and signed by a
Responsible Officer of the Borrower. Each Borrowing of, conversion to or
continuation of LIBO Rate Loans shall be in a principal amount of $1,000,000 or
a whole multiple of $1,000,000 in excess thereof. Each Borrowing of or
conversion to Base Rate Loans shall be in a principal amount of $500,000 or a
whole multiple of $100,000 in excess thereof. Each Notice of Advance shall
specify (i) whether the Borrower is requesting a Borrowing, a conversion of
Loans from one Type to the other, or a continuation of Loans as the same Type,
(ii) the requested date of the Borrowing, conversion or continuation, as the
case may be (which shall be a Business Day), (iii) the principal amount of Loans
to be borrowed, converted or continued, (iv) the Type of Loans to be borrowed or
to which existing Loans are to be converted, and (v) if applicable, the duration
of the Interest Period with respect thereto. If the Borrower fails to specify a
Type of Loan in a Notice of Advance or if the Borrower fails to give a timely
notice requesting a conversion or continuation, then the applicable Loans shall
be made or continued as, or converted to, Base Rate Loans. Any such automatic
conversion to Base Rate Loans shall be effective as of the last day of the
Interest Period then in effect with respect to the applicable LIBO Rate Loans.
If the Borrower requests a Borrowing of, conversion to, or continuation of LIBO
Rate Loans in any such Notice of Advance, 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 Notice of Advance, the Administrative Agent
shall promptly notify each Lender of its Percentage 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. 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 2:00 p.m. central time, on the Business Day
specified in the applicable Notice of Advance. Upon satisfaction of the
applicable conditions set forth in Section 4.2 (and, if such Borrowing is the
initial Credit Extension, Section 4.1), 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

                                       21
<PAGE>

on the books of BMO with the amount of such funds or (ii) wire transfer of such
funds, in each case in accordance with instructions provided to the
Administrative Agent by the Borrower; provided, however, that if, on the date of
the Borrowing 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. Unless the
Administrative Agent shall have received prompt notice from a Lender that such
Lender will not make available to the Administrative Agent such Lender's Loans,
the Administrative Agent may in its discretion assume that such Lender has made
such Loans available to the Administrative Agent in accordance with this section
and the Administrative Agent may if it chooses, in reliance upon such
assumption, make such Loan available to the Borrower. If and to the extent such
Lender shall not so make its Loan available to the Administrative Agent, such
Lender and the Borrower severally agree to pay or repay to the Administrative
Agent within two Business Days after demand the amount of such Loan together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is paid or repaid to the
Administrative Agent, to be calculated as to such Lender at the Federal Funds
Rate, and to be calculated as to the Borrower at the interest rate applicable at
the time to the other Loans made on such date. If any Lender fails to make such
payment to the Administrative Agent within such two Business Day period, such
Lender shall in addition to such amount pay interest thereon, for each day from
the date such Loan is made available to the Borrower until the date such amount
is paid or repaid to the Administrative Agent, at the interest rate applicable
at the time to the other Loans made on such date. The failure of any Lender to
make any Loan to be made by it hereunder shall not relieve any other Lender of
its obligation hereunder, if any, to make its Loan, but no Lender shall be
responsible for the failure of any other Lender to make any Loan to be made by
such other Lender.

      (c) Except as otherwise provided herein, a LIBO Rate Loan may be continued
or converted only on the last day of the Interest Period for such LIBO Rate
Loan. During the existence of a Default, Event of Default or Borrowing Base
Deficiency, no Loans may be requested as, converted to or continued as LIBO Rate
Loans.

      (d) The Administrative Agent shall promptly notify the Borrower and the
Lenders of the interest rate applicable to any LIBO Rate Loan upon determination
of such interest rate. The determination of the LIBO Rate by the Administrative
Agent shall be conclusive in the absence of manifest error. The Administrative
Agent shall notify the Borrower and the Lenders of any change in BMO's prime
rate used in determining the Base Rate promptly following the public
announcement of such change.

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

      SECTION 2.3 LETTERS OF CREDIT.

      2.3.1 The Letter of Credit Commitment.

            (i) Subject to the terms and conditions set forth herein, (A) the
      Issuing Bank agrees, in reliance upon the agreements of the other Lenders
      set forth in this Section 2.3, (1) from time to time on any Business Day
      during the period from the Closing Date until the Letter of Credit
      Availability Expiration Date, to issue Letters of Credit for the account
      of the Borrower or certain Subsidiaries, and to amend or renew Letters of
      Credit previously issued by it, in accordance with subsection 2.3.2 below,
      and (2) to honor drafts under the Letters of Credit; and (B) the Lenders
      severally agree to participate in Letters of Credit issued for the account
      of the

                                       22
<PAGE>

      Borrower; provided that the Issuing Bank 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, (x) the Outstanding Amount of all
      L/C Obligations and all Loans would exceed the lesser of (A) the Aggregate
      Commitments on such date and (B) the Borrowing Base then in effect minus
      the aggregate principal amount of all 1999 Senior Notes then outstanding,
      and, (y) the aggregate Outstanding Amount of the Loans of any Lender, plus
      such Lender's Percentage Share of the Outstanding Amount of all L/C
      Obligations would exceed such Lender's Commitment or such Lender's
      Percentage Share of (x) the Borrowing Base minus (y) the aggregate
      principal amount of all 1999 Senior Notes then outstanding, or (z) the
      Outstanding Amount of the L/C Obligations would exceed the Letter of
      Credit Sublimit. 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 Issuing Bank shall be under no obligation to issue any
      Letter of Credit if:

                        (A) 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 Majority Lenders acting in their
                  sole discretion have approved in writing such expiry date;

                        (B) the expiry date of such requested Letter of Credit
                  would occur after the Letter of Credit Availability Expiration
                  Date, unless all the Lenders acting in their sole discretion
                  have approved in writing such expiry date;

                        (C) the issuance of such Letter of Credit would violate
                  one or more policies of the Issuing Bank;

                        (D) such Letter of Credit is in a face amount less than
                  $100,000, or denominated in a currency other than Dollars,
                  unless all the Lenders acting in their sole discretion have
                  approved in writing the issuance of Letters of Credit
                  denominated in a currency other than Dollars; or

                        (E) such Letter of Credit is to be used directly or
                  indirectly to assure payment of or otherwise support any
                  Person's Indebtedness for borrowed money;

                        (F) the issuance of such Letter of Credit is not in
                  compliance with all applicable governmental restrictions,
                  policies, and guidelines (whether or not having the force of
                  law) or it subjects the Issuing Bank to any cost not
                  anticipated by the Issuing Bank on the date hereof;

                                       23
<PAGE>

                        (G) the form and terms of such Letter of Credit are not
                  acceptable to the Administrative Agent and Issuing Bank in
                  their sole and absolute discretion; and

                        (H) any other condition in this Agreement to the
                  issuance of such Letter of Credit has not been satisfied.

            (iii) The Issuing Bank shall be under no obligation to amend any
      Letter of Credit if (A) the Issuing Bank 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.

      2.3.2 Procedures for Issuance and Amendment of 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 Issuing Bank
      (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 Issuing Bank and the Administrative Agent not later than
      12:00 p.m., central time at least two Business Days (or such later date
      and time as the Issuing Bank 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 Issuing Bank: (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 Issuing Bank 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 Issuing Bank (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 Issuing Bank may require.

            (ii) Promptly after receipt of any Letter of Credit Application, the
      Issuing Bank 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 Issuing
      Bank will provide the Administrative Agent with a copy thereof. Upon
      receipt by the Issuing Bank 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
      Issuing Bank 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 Issuing Bank'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
      unconditionally agrees to and hereby does, purchase from the Issuing Bank
      a participation in such Letter of Credit in an amount equal to the product
      of such Lender's Percentage Share times the amount of such Letter of
      Credit.

                                       24
<PAGE>

      2.3.3 Drawings and Reimbursements; Funding of Participations.

            (i) Upon any drawing under any Letter of Credit, the Issuing Bank
      shall notify the Borrower and the Administrative Agent thereof. Not later
      than 12:00 p.m., central time, on the date of any payment by the Issuing
      Bank under a Letter of Credit (each such date, an "Honor Date"), the
      Borrower shall reimburse the Issuing Bank through the Administrative Agent
      in an amount equal to the amount of such drawing. If the Borrower fails to
      so reimburse the Issuing Bank 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 such Lender's
      Percentage Share thereof. In such event, the Borrower shall be deemed to
      have requested a Borrowing of Base Rate 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 2.2 for the principal amount of
      Base Rate Loans, but subject to the amount of the unutilized portion of
      the lesser of (x) the Aggregate Commitments and (y) the Borrowing Base
      then in effect and the conditions set forth in Section 4.2 (other than the
      delivery of a Notice of Advance). Any notice given by the Issuing Bank or
      the Administrative Agent pursuant to this Section 2.3.3(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 Issuing Bank) shall
      upon any notice from the Administrative Agent pursuant to Section 2.3.3(i)
      make funds available to the Administrative Agent for the account of the
      Issuing Bank at the Administrative Agent's Office in an amount equal to
      such Lender's Percentage Share of the Unreimbursed Amount not later than
      1:00 p.m., central time, on the Business Day specified in such notice by
      the Administrative Agent, whereupon, subject to the provisions of Section
      2.3.3(iii), each Lender that so makes funds available shall be deemed to
      have made a Base Rate Loan to the Borrower in such amount. The
      Administrative Agent shall remit the funds so received to the Issuing
      Bank.

            (iii) With respect to any Unreimbursed Amount that is not fully
      refinanced by a Borrowing of Base Rate Loans because the conditions set
      forth in Section 4.2 cannot be satisfied or for any other reason, the
      Borrower shall be deemed to have incurred from the Issuing Bank 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 Issuing Bank pursuant to Section 2.3.3(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 2.3.3.

            (iv) Until each Lender funds its Loan or L/C Advance pursuant to
      this Section 2.3.3 to reimburse the Issuing Bank for any amount drawn
      under any Letter of Credit, interest in respect of such Lender's
      Percentage Share of such amount shall be solely for the account of the
      Issuing Bank.

            (v) Each Lender's obligation to make Loans or L/C Advances to
      reimburse the Issuing Bank for amounts drawn under Letters of Credit, as
      contemplated by this Section

                                       25
<PAGE>

      2.3.3, 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 Issuing
      Bank, the Borrower or any other Person for any reason whatsoever; (B) the
      occurrence or continuance of a Default or Event of Default, or (C) any
      other occurrence, event or condition, whether or not similar to any of the
      foregoing. Any such reimbursement shall not relieve or otherwise impair
      the obligation of the Borrower to reimburse the Issuing Bank for the
      amount of any payment made by the Issuing Bank 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 Issuing Bank any amount required to be paid
      by such Lender pursuant to the foregoing provisions of this Section 2.3.3
      by the time specified in Section 2.3.3(ii), the Issuing Bank 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 Issuing Bank at a rate per annum equal to (1)
      for the first two Business Days immediately following the date such
      payment is required, the Federal Funds Rate from time to time in effect,
      and (2) for each day thereafter, the Base Rate from time to time in
      effect. A certificate of the Issuing Bank submitted to any Lender (through
      the Administrative Agent) with respect to any amounts owing under this
      clause (vi) shall be conclusive absent manifest error.

      2.3.4 Repayment of Participations.

            (i) At any time after the Issuing Bank 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 2.3.3, if
      the Administrative Agent receives for the account of the Issuing Bank any
      payment related to such Letter of Credit (whether directly from the
      Borrower or otherwise, including proceeds of Cash Collateral applied
      thereto by the Administrative Agent), or any payment of interest thereon,
      the Administrative Agent will distribute to such Lender its Percentage
      Share thereof 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 Issuing Bank pursuant to Section 2.3.3 is required to be
      returned, each Lender shall pay to the Administrative Agent for the
      account of the Issuing Bank its Percentage 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 (1) with respect to the first two Business Days immediately
      following such demand, the Federal Funds Rate from time to time in effect,
      and (2) with respect to each day thereafter, the Base Rate from time to
      time in effect.

      2.3.5 Obligations Absolute. The obligation of the Borrower to reimburse
the Issuing Bank for each drawing under each Letter of Credit, and to repay each
L/C Borrowing and each drawing under a Letter of Credit that is refinanced by a
Borrowing of Loans, 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:

                                       26
<PAGE>

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

            (ii) the existence of any claim, counterclaim, set-off, defense or
      other right that the Borrower 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 Issuing Bank
      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 Issuing Bank under such Letter of Credit
      against presentation of a draft or certificate that does not strictly
      comply with the terms of such Letter of Credit; or any payment made by the
      Issuing Bank 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.

            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
      irregularity, the Borrower will promptly notify the Issuing Bank. The
      Borrower shall be conclusively deemed to have waived any such claim
      against the Issuing Bank and its correspondents unless such notice is
      given as aforesaid.

      2.3.6 Role of Issuing Bank; Indemnity. Each Lender and the Borrower agree
that, in paying any drawing under a Letter of Credit, the Issuing Bank 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. No
Agent-Related Person nor any of the respective correspondents, participants or
assignees of the Issuing Bank 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 Majority 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. No Agent-Related
Person, nor any of the respective correspondents, participants or assignees of
the Issuing Bank, shall be liable or responsible for any of the matters
described in clauses (i) through (v) of Section 2.3.5. The Borrower agrees to

                                       27
<PAGE>

hold Issuing Bank and each Lender harmless and indemnified against any liability
or claim in connection with or arising out of the subject matter of this
section, WHICH INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM
IS IN ANY WAY OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT
OR OMISSION OF ANY KIND BY ISSUING BANK OR ANY LENDER, provided only that the
Issuing Bank or such Lender shall not be entitled to indemnification for that
portion, if any, of any liability or claim which is proximately caused by its
own individual gross negligence or willful misconduct as determined in a final
judgment. In furtherance and not in limitation of the foregoing, the Issuing
Bank 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 Issuing Bank 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. If any Letter of Credit provides that it
is transferable, the Issuing Bank shall have no duty to determine the proper
identity of anyone appearing as transferee of such Letter of Credit, nor shall
the Issuing Bank be charged with responsibility of any nature or character for
the validity or correctness of any transfer or successive transfers, and payment
by the Issuing Bank to any purported transferee or transferees as determined by
the Issuing Bank is hereby authorized and approved, and the Borrower further
agrees to hold the Issuing Bank and each Lender harmless and indemnified against
any liability or claim in connection with or arising out of the foregoing, WHICH
INDEMNITY SHALL APPLY WHETHER OR NOT ANY SUCH LIABILITY OR CLAIM IS IN ANY WAY
OR TO ANY EXTENT CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION
OF ANY KIND BY THE ISSUING BANK OR ANY LENDER, provided only that the Issuing
Bank or such Lender shall not be entitled to indemnification for that portion,
if any, of any liability or claim which is caused by its own individual gross
negligence or willful misconduct. All of Borrower's Obligations under this
Section 2.3.6 shall survive termination of the Commitments or of this Agreement
and repayment in full of the Obligations.

      2.3.7 Applicability of ISP98 and UCP. Unless otherwise expressly agreed by
the Issuing Bank and the Borrower when a Letter of Credit is issued, (i) the
rules of the "International Standby Practices 1998" published by the Institute
of International Banking Law & Practice (or such later version thereof as may be
in effect at the time of issuance) 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.

      2.3.8 Letter of Credit Fees. The Borrower shall pay to the Administrative
Agent for the account of each Lender in accordance with its Percentage Share a
Letter of Credit fee for each Letter of Credit equal to the LIBOR Spread then in
effect with respect to Loans after giving effect to the L/C Obligations incurred
with respect to such Letter of Credit times the actual daily maximum amount
available to be drawn under such Letter of Credit. Such fee for each Letter of
Credit 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, and on the Letter of Credit Availability
Expiration Date. If there is any change in the LIBOR Spread during any quarter,
the actual daily amount of each Letter of Credit shall be computed and
multiplied by the

                                       28
<PAGE>

LIBOR Spread with respect to Letters of Credit separately for each period during
such quarter that such LIBOR Spread was in effect.

      2.3.9 Letter of Credit Fronting Fee and Documentary and Processing Charges
Payable to Issuing Bank. The Borrower shall pay directly to the Issuing Bank for
its own account a fronting fee in an amount equal to 0.1875% per annum on the
daily maximum amount available to be drawn thereunder, 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 issuance of such Letter
of Credit, and on the Letter of Credit Availability Expiration Date; provided
that all such fees shall be payable on the date on which the Commitments
terminate and any such fees accruing after the date on which the Commitments
terminate shall be payable on demand. In addition, the Borrower shall pay
directly to the Issuing Bank for its own account the customary issuance,
presentation, amendment and other processing fees, and other standard costs and
charges, of the Issuing Bank relating to letters of credit as from time to time
in effect. Such fees and charges are due and payable on demand and are
nonrefundable. All participation fees and fronting fees shall be computed on the
basis of a year of 360 days and shall be payable for the actual number of days
elapsed (including the first day but excluding the last day).

      2.3.10 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.

      2.3.11 L/C Collateral.

      (a) L/C Obligations in Excess of Borrowing Base or upon Termination of
Commitments. (i) If, after the making of all mandatory prepayments required
under Section 2.4.2, the aggregate amount of all Loans outstanding plus all L/C
Obligations outstanding excluding L/C Obligations secured by cash collateral
pursuant to this Section 2.3.11 will exceed the Borrowing Base, then the
Borrower will immediately pay to the Issuing Bank an amount in cash equal to
such excess, or (ii) should any L/C Obligations remain outstanding on the
Maturity Date, then the Borrower will immediately pay the Issuing Bank an amount
in cash equal to the aggregate amount of such Issuing Bank's L/C Obligations.
The Issuing Bank will hold such amount as security for the remaining L/C
Obligations ("L/C Collateral") until such L/C Obligations become Matured L/C
Obligations, at which time such L/C Collateral may be applied to such Matured
L/C Obligations. Neither this subsection nor the following subsection shall,
however, limit or impair any rights which the Issuing Bank may have under any
other document or agreement relating to any Letter of Credit or L/C Obligation,
including any Letter of Credit Application, or any rights which the Issuing Bank
or Lenders may have to otherwise apply any payments by the Borrower and L/C
Collateral under Section 2.3.11.

      (b) Acceleration of L/C Obligations. If the Obligations or any part
thereof become immediately due and payable pursuant to Section 8.2 then, unless
the Majority Lenders otherwise specifically elect to the contrary (which
election may thereafter be retracted by the Majority Lenders at any time), all
L/C Obligations shall become immediately due and payable without regard to
whether or not actual drawings or payments on the Letters of Credit have
occurred, and the Borrower shall be obligated to pay to the Issuing Bank
immediately an amount equal to the aggregate L/C Obligations which are then
outstanding. All amounts so paid shall first be applied to Matured L/C
Obligations and then held by the Issuing Bank as L/C Collateral until such L/C
Obligations become

                                       29
<PAGE>

Matured L/C Obligations, at which time such L/C Collateral shall be applied to
such Matured L/C Obligations.

      (c) Investment of L/C Collateral. Pending application thereof, all L/C
Collateral shall be invested by the Issuing Bank in such blocked account as the
Issuing Bank may choose in its sole discretion reasonably exercised. All
interest on such investments shall be reinvested or applied to Matured L/C
Obligations. When all Obligations have been satisfied in full, including all L/C
Obligations, all Letters of Credit have expired or been terminated, and all of
the Borrower's reimbursement obligations in connection therewith have been
satisfied in full, the Issuing Bank shall release any remaining L/C Collateral.
The Borrower hereby assigns and grants to the Issuing Bank a continuing security
interest in all L/C Collateral paid by it to the Issuing Bank, all investments
purchased with such L/C Collateral, and all proceeds thereof to secure its
Matured L/C Obligations and its Obligations under this Agreement, the Notes, and
the other Loan Documents, and the Borrower agrees that such L/C Collateral and
investments shall be subject to all of the terms and conditions of the
Borrower's Security Agreement. The Borrower further agrees that the Issuing Bank
shall have all of the rights and remedies of a secured party under the Uniform
Commercial Code as adopted in the State of New York with respect to such
security interest and that an Event of Default under this Agreement shall
constitute a default for purposes of such security interest.

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

      SECTION 2.4 PREPAYMENTS.

      2.4.1 Voluntary Prepayments. The Borrower may, upon notice to the
Administrative Agent, at any time or from time to time voluntarily prepay Loans
in whole or in part without premium or penalty; provided that (i) such notice
must be received by the Administrative Agent not later than 12:00 p.m., central
time, (A) three Business Days prior to any date of prepayment of LIBO Rate
Loans, and (B) on the date of prepayment of Base Rate Loans; (ii) any prepayment
of LIBO Rate Loans shall be in a principal amount of $1,000,000 or a whole
multiple of $1,000,000 in excess thereof; and (iii) any prepayment of Base Rate
Loans shall be in a principal amount of $500,000 or a whole multiple of $100,000
in excess thereof. Each such notice shall specify the date and amount of such
prepayment and the Type(s) of Loans to be prepaid. The Administrative Agent will
promptly notify each Lender of its receipt of each such notice, and of such
Lender's Percentage 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 LIBO Rate Loan shall be accompanied by all accrued interest
thereon, together with any additional amounts required pursuant to Section 3.5.
Each such prepayment shall be applied to the Loans of the Lenders in accordance
with their respective Percentage Shares.

      2.4.2 Mandatory Prepayments. The Borrower shall make the following
prepayments of the Loans:

            (i) Outstandings Exceed Commitments. If for any reason the
      Outstanding Amount of all Loans and L/C Obligations at any time exceeds
      the Aggregate Commitments then in effect, the Borrower shall first
      immediately prepay Loans and second following

                                       30
<PAGE>

      repayment of the Loans, Cash Collateralize the L/C Obligations in an
      aggregate amount equal to such excess.

            (ii) Borrowing Base Deficiency.

                        (A) If at any time the aggregate unpaid principal
                  balance of the Loans plus the aggregate amount of L/C
                  Obligations exceeds the Borrowing Base (a "Borrowing Base
                  Deficiency"), the Borrower shall, within thirty (30) days
                  after the Administrative Agent sends written notice of such
                  fact to the Borrower, (1) prepay the principal of the Loans
                  (and, upon prepayment of all Loans, shall, to the extent
                  required, provide L/C Collateral as set forth in Section
                  2.3.11) in an aggregate amount at least equal to such
                  Borrowing Base Deficiency (in this section, a "Mandatory
                  Prepayment Amount"), or (2) give notice to the Administrative
                  Agent electing to prepay such Mandatory Prepayment Amount in
                  six (6) (or fewer) monthly installments. Each such installment
                  shall equal or exceed one-sixth of such Borrowing Base
                  Deficiency; the first such installment shall be paid within
                  thirty (30) days of the giving of such notice of the Borrowing
                  Base Deficiency by the Administrative Agent to the Borrower
                  and the five (or fewer) subsequent installments shall be due
                  and payable at one month intervals thereafter until such
                  Borrowing Base Deficiency has been eliminated.

                        (B) If (1) at any time during the existence or
                  continuation of a Borrowing Base Deficiency, the Borrower or
                  any Guarantor makes a Disposition of assets (other than those
                  described in clauses (a) through (d) of Section 7.5 hereof),
                  or (2) a Disposition of assets included in the Borrowing Base
                  results in a reduction of the Borrowing Base in accordance
                  with Section 7.5(e) such that a Borrowing Base Deficiency
                  occurs, then, in either case, the Borrower shall, or shall
                  cause such Guarantor to, use the Net Sale Proceeds from such
                  Disposition (whether or not such assets are included in the
                  Borrowing Base) to prepay the Loans and, upon prepayment of
                  all Loans, shall provide L/C Collateral as set forth in
                  Section 2.3.11, within one (1) Business Day of such
                  Disposition in an amount equal to 100% of the Borrowing Base
                  Deficiency then existing or occurring as a result of such
                  disposition. Application of such Net Sales Proceeds shall be
                  applied to the principal amount of the Loans until the Loans
                  are paid in full and then shall be held as L/C Collateral in
                  an amount equal to the aggregate amount of L/C Obligations
                  pursuant to Section 2.3.11.

      SECTION 2.5 REDUCTION OR TERMINATION OF COMMITMENTS AND MAXIMUM LOAN
AMOUNT. The Borrower may, upon notice to the Administrative Agent, terminate the
Aggregate Commitments and Maximum Loan Amount, or permanently reduce the
Aggregate Commitments and Maximum Loan Amount to an amount not less than the
then Outstanding Amount of all Loans and L/C Obligations; provided that (i) any
such notice shall be received by the Administrative Agent not later than 12:00
p.m., central time three (3) Business Days prior to the date of termination or
reduction, and (ii) any such partial reduction shall be in an aggregate amount
of $5,000,000 or any whole multiple of $1,000,000 in excess thereof. The
Administrative Agent shall promptly notify the Lenders of any such notice of
reduction or termination of the Aggregate Commitments and

                                       31
<PAGE>

Maximum Loan Amount. Once reduced in accordance with this Section, the
Commitments may not be increased. Any reduction of the Aggregate Commitments
shall be applied to the Commitment of each Lender according to its Percentage
Share. All commitment fees accrued until the effective date of any termination
of the Aggregate Commitments shall be paid on the effective date of such
termination.

      SECTION 2.6 REPAYMENT OF LOANS. The Borrower shall repay to the Lenders on
the Maturity Date the aggregate principal amount of Loans outstanding on such
date.

      SECTION 2.7 INITIAL BORROWING BASE. On any date during the period from the
Closing Date to the first Evaluation Date, the Borrowing Base shall be an amount
equal to (i) $300,000,000.

      SECTION 2.8 SUBSEQUENT DETERMINATIONS OF BORROWING BASE.

      (a) By each Evaluation Date, the Borrower shall furnish to the
Administrative Agent and each Lender all information, reports and data which the
Administrative Agent has then reasonably requested concerning the Borrower's and
the Guarantors' businesses and properties (including Borrower's and the
Guarantors' Oil and Gas Properties and interests and the reserves and production
relating thereto), together with the Engineering Report described in Section
6.2(g), if an Engineering Report is then due. Within thirty (30) days after
receiving such information, reports and data, or as promptly thereafter as
practicable, the Administrative Agent shall recommend a redetermined Borrowing
Base to the Lenders. Such recommended Borrowing Base shall become effective upon
the receipt by the Administrative Agent of the approval of the Majority Lenders.
The failure of a Lender to respond or object to the recommended Borrowing Base
within fifteen (15) days after notice thereof is given to such Lender by the
Administrative Agent shall be deemed an acceptance and approval of such
recommended Borrowing Base by such Lender. If such recommended Borrowing Base is
not approved by Majority Lenders within fifteen (15) days after the
Administrative Agent submits the recommended Borrowing Base to the Lenders, then
each Lender shall submit in writing to the Administrative Agent, on or within
fifteen (15) days after the Administrative Agent notifies the Lenders that the
Lenders have not approved any such recommended Borrowing Base, such Lender's
determination of the redetermined Borrowing Base; in such case, the redetermined
Borrowing Base shall be the highest amount approved by the Majority Lenders.
NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, WITHOUT THE PRIOR WRITTEN
APPROVAL OF ALL OF THE LENDERS, SUCH APPROVAL TO BE IN EACH LENDER'S SOLE
DISCRETION, THE REDETERMINED BORROWING BASE SHALL NOT BE INCREASED ABOVE THE
AMOUNT OF THE BORROWING BASE IN EFFECT IMMEDIATELY PRIOR TO SUCH
REDETERMINATION. The Administrative Agent shall by notice to the Borrower and
the Lenders designate the amount of the Borrowing Base (determined by the
Majority Lenders or all of the Lenders, as applicable, in accordance with the
foregoing procedures) available to the Borrower hereunder, which designation
shall take effect immediately on the date such notice is sent (a "Determination
Date") and shall remain in effect until but not including the next date as of
which the Borrowing Base is redetermined. If the Borrower does not furnish all
such information, reports and data by the date specified in the first sentence
of this section, the Administrative Agent may nonetheless designate the
Borrowing Base at any amount which the Lenders determine, and may redesignate
the Borrowing Base from time to time thereafter at any amount which all Lenders
redetermine, until each Lender receives all such information, reports and data,
whereupon Lenders shall designate a new Borrowing Base as described above. The
Lenders shall determine the amount of the Borrowing Base based upon the loan
collateral value which they, in their sole discretion and in

                                       32
<PAGE>

accordance with their respective normal practices and standards for oil and gas
loans as such practices and standards exist at the particular time, assign to
the various Oil and Gas Properties of the Borrower or the Guarantors at the time
in question and based upon such other factors (including without limitation the
assets, liabilities, fixed charges, cash flow, business, properties, prospects,
management and ownership of any of the Borrower or the Guarantors or any
Subsidiary of any of the Borrower or the Guarantors) as they, in their sole
discretion and in accordance with their respective normal practices and
standards for oil and gas loans as such practices and standards exist at the
particular time, deem significant. It is expressly understood that Lenders and
the Administrative Agent have no obligation to agree upon or designate the
Borrowing Base at any particular amount, whether in relation to the Maximum Loan
Amount or otherwise, and that the Lenders' commitments to advance funds
hereunder is determined by reference to the Borrowing Base from time to time in
effect, which Borrowing Base shall be used for calculating commitment fees under
Section 2.10(a). Additional redeterminations at the request of the Lenders, the
Administrative Agent or the Borrower shall be subject to a $5,000 engineering
fee payable by Borrower to the Administrative Agent for its own account.

      (b) The Borrower may include additional Oil and Gas Properties of the
Borrower or the Guarantors acquired from time to time as Collateral for the
Obligations, which may then be included in the calculation of the Borrowing
Base, by the Borrower (A) giving written notice to the Administrative Agent of
such properties to be included, (B) subjecting such properties to Liens securing
the Obligations (pursuant to Security Documents satisfactory to the
Administrative Agent) if necessary to comply with the provisions of Section
6.16, (C) including such properties in an Engineering Report submitted to the
Administrative Agent and (D) delivering to the Administrative Agent title
opinions covering at least 80% of the additional value of such properties
addressed to the Administrative Agent for the benefit of the Lenders covering
all of such properties and other legal opinions from counsel acceptable to the
Administrative Agent, in its sole discretion, in form, scope and substance
acceptable to the Administrative Agent opining favorably as to, among such other
matters as may be required by the Administrative Agent, (1) the Borrower's or
the appropriate Guarantor's ownership of such properties and (2) matters of the
type covered by the opinions delivered pursuant to Section 4.1(a)(vi).

      (c) In addition to the any scheduled determination or discretionary
determination of the Borrowing Base, the Borrowing Base shall be automatically
reduced from time to time as set forth in Section 7.5(e).

      SECTION 2.9 INTEREST.

      (a) Subject to the provisions of subsection (b) below, (i) each LIBO Rate
Loan shall bear interest on the outstanding principal amount thereof for each
Interest Period at a rate per annum equal to the Adjusted LIBO Rate for such
Interest Period plus the LIBOR Spread; 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 Base Rate
Spread.

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

                                       33
<PAGE>

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

      SECTION 2.10 FEES. In addition to certain fees described in Sections 2.3.8
and 2.3.9:

      (a) Commitment Fee. The Borrower shall pay to the Administrative Agent for
the account of each Lender in accordance with its Percentage Share, a commitment
fee equal to the Commitment Fee Rate times the actual daily amount by which the
Aggregate Commitments exceed the sum of (i) the Outstanding Amount of Loans and
(ii) the Outstanding Amount of L/C Obligations; provided, however, that so long
as there remains outstanding any 1999 Senior Notes, the Borrower shall pay to
the Administrative Agent for the account of each Lender in accordance with its
Percentage Share, a commitment fee equal to the Commitment Fee Rate times the
actual daily amount by which the Borrowing Base exceeds the sum of (i) the
Outstanding Amount of Loans and (ii) the Outstanding Amount of L/C Obligations.
The commitment fee shall accrue at all times from the Closing Date until the
Maturity Date 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 Maturity Date. The
commitment fee shall be calculated quarterly in arrears, and if there is any
change in the Commitment Fee Rate with respect to Commitment fees during any
quarter, the actual daily amount shall be computed and multiplied by the
Commitment Fee Rate with respect to Commitment fees separately for each period
during such quarter that such Commitment Fee Rate was in effect. The commitment
fee shall accrue at all times, including at any time during which one or more of
the conditions in Article IV is not met.

      (b) Arrangement and Agency Fees. The Borrower shall pay an arrangement fee
to the Arranger for the Arranger's own account, and shall pay an agency fee to
the Administrative Agent for the Administrative Agent's own account, in the
amounts and at the times specified in the letter agreement, dated February 9,
2004 (the "Agent and Arranger Fee Letter"), among the Borrower, the Arranger and
the Administrative Agent. Such fees shall be fully earned when paid and shall be
nonrefundable for any reason whatsoever.

      SECTION 2.11 COMPUTATION OF INTEREST AND FEES. Computation of interest on
Base Rate Loans and Commitment Fees shall be calculated on the basis of a year
of 365 or 366 days, as the case may be, and the actual number of days elapsed.
Computation of all other types of interest and all fees shall be calculated on
the basis of a year of 360 days and the actual number of days elapsed, which
results in a higher yield to the payee thereof than a method based on a year of
365 or 366 days. Interest shall accrue on each Loan for the day on which the
Loan is made, and shall not accrue on a Loan, or any portion thereof, for the
day on which the Loan or such portion is paid, provided that any Loan that is
repaid on the same day on which it is made shall bear interest for one day.

      SECTION 2.12 NOTES AND OTHER EVIDENCE OF DEBT.

      (a) The obligation of the Borrower to repay to each Lender the aggregate
amount of all Loans made by such Lender (such Lender's "Loan"), together with
interest accruing in connection therewith, shall be evidenced by a single
promissory note (such Lender's "Note") made by the Borrower in the amount of
such Lender's Percentage Share of the Maximum Loan Amount payable

                                       34
<PAGE>

to the order of such Lender substantially in the form of Exhibit B with
appropriate insertions. Each Lender may record the date, Type (if applicable),
amount and maturity of the applicable Loans and payments with respect thereto in
one or more schedules to its Note or on 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 so to 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 Loans and L/C Obligations.

      (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
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.

      SECTION 2.13 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 12:00 noon,
central time, on the date specified herein. The Administrative Agent will
promptly distribute to each Lender its Percentage Share (or other applicable
share as provided herein) of such payment in like funds as received by wire
transfer to such Lender's Lending Office. All payments received by the
Administrative Agent after 12:00 noon, central time, shall be deemed received on
the next succeeding Business Day and any applicable interest or fee shall
continue to accrue.

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

      (c) 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 (1) in respect of each of
      the first two Business Days from and including the date such amount was
      made available by the Administrative Agent to such Lender to the date such
      amount is

                                       35
<PAGE>

      repaid to the Administrative Agent in immediately available funds, at the
      Federal Funds Rate from time to time in effect, and (2) in respect of each
      day after the first two Business Days 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 Base 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 (1) for the
      first two Business Days of any Compensation Period, the Federal Funds Rate
      from time to time in effect, and (2) for each other day of any
      Compensation Period, the interest rate applicable to the applicable
      Borrowing. If such Lender pays such amount to the Administrative Agent,
      then such amount shall constitute such Lender's Loan included in the
      applicable Borrowing. If such Lender does not pay such amount forthwith
      upon the Administrative Agent's 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 that 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 with respect to any
amount owing under this subsection (c) shall be conclusive, absent manifest
error.

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

      (e) 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.

      (f) 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.

      SECTION 2.14 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)

                                       36
<PAGE>

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 Loan or such participations, as
the case may be, pro rata with each of them; provided, however, that if all or
any portion of such excess payment is thereafter recovered from the purchasing
Lender, such purchase shall to that extent be rescinded and each other Lender
shall repay to the purchasing Lender the purchase price paid therefor, together
with an amount equal to such paying Lender's ratable share (according to the
proportion of (i) the amount of such paying Lender's required repayment to (ii)
the total amount so recovered from the purchasing Lender) of any interest or
other amount paid or payable by the purchasing Lender in respect of the total
amount so recovered. The Borrower agrees that any Lender so purchasing a
participation from another Lender may, to the fullest extent permitted by law,
exercise all its rights of payment (including the right of set-off, but subject
to Section 10.9) with respect to such participation as fully as if such Lender
were the direct creditor of the Borrower in the amount of such participation.
The Administrative Agent will keep records (which shall be conclusive and
binding in the absence of manifest error) of participations purchased under this
Section and will in each case notify the Lenders following any such purchases or
repayments. Each Lender that purchases a participation pursuant to this Section
shall from and after such purchase have the right to give all notices, requests,
demands, directions and other communications under this Agreement with respect
to the portion of the Obligations purchased to the same extent as though the
purchasing Lender were the original owner of the Obligations purchased.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

      SECTION 3.1 TAXES.

      (a) Any and all payments by the Borrower to or for the account of the
Administrative Agent or any Lender under any Loan Document shall be made free
and clear of and without deduction for any and all present or future taxes,
duties, levies, imposts, deductions, assessments, fees, withholdings or similar
charges, and all liabilities with respect thereto, excluding, in the case of the
Administrative Agent and each Lender, taxes imposed on or measured by its net
income, and franchise taxes imposed on it (in lieu of net income taxes), by the
jurisdiction (or any political subdivision thereof) under the Laws of which the
Administrative 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 the Borrower shall be
required by any Laws to deduct any Taxes from or in respect of any sum payable
under any Loan Document to the Administrative Agent or any Lender, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section), the Administrative Agent and such Lender receives an amount equal
to the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions, (iii) the Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable Laws, and (iv) within 30 days after the date of such
payment, the Borrower 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

                                       37
<PAGE>

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 the
Administrative Agent or any Lender, the Borrower shall also pay to the
Administrative Agent (for the account of such Lender) or to such Lender, at the
time interest is paid, such additional amount that such Lender specifies as
necessary to preserve the after-tax yield (after factoring in all taxes,
including taxes imposed on or measured by net income) such Lender would have
received if such Taxes or Other Taxes had not been imposed.

      (d) The Borrower agrees to indemnify the Administrative Agent and each
Lender for (i) the full amount of Taxes and Other Taxes (including any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section) paid by the Administrative Agent and such Lender, (ii) amounts
payable under Section 3.1(c) and (iii) any liability (including 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.

      SECTION 3.2 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 LIBO
Rate Loans, or materially restricts the authority of such Lender to purchase or
sell, or to take deposits of, Dollars in the applicable offshore Dollar market,
or to determine or charge interest rates based upon the LIBO Rate, then, on
notice thereof by such Lender to the Borrower through the Administrative Agent,
any obligation of such Lender to make or continue LIBO Rate Loans or to convert
Base Rate Loans to LIBO 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 LIBO Rate Loans of such Lender to Base
Rate Loans, either on the last day of the Interest Period thereof, if such
Lender may lawfully continue to maintain such LIBO Rate Loans to such day, or
immediately, if such Lender may not lawfully continue to maintain such LIBO Rate
Loans. Upon any such prepayment or conversion, the Borrower shall also pay
interest on the amount so prepaid or converted. Each Lender agrees to designate
a different Lending Office if such designation will avoid the need for such
notice and will not, in the good faith judgment of such Lender, otherwise be
materially disadvantageous to such Lender.

      SECTION 3.3 INABILITY TO DETERMINE RATES. If the Administrative Agent
determines in connection with any request for a LIBO Rate Loan or a conversion
to or continuation thereof that (a) Dollar deposits are not being offered to
banks in the applicable offshore Dollar market for the applicable amount and
Interest Period of such LIBO Rate Loan, (b) adequate and reasonable means do not
exist for determining the LIBO Rate for such LIBO Rate Loan, or (c) the Adjusted
LIBO Rate for such LIBO Rate Loan does not adequately and fairly reflect the
cost to the Lenders of funding such LIBO Rate Loan, the Administrative Agent
will promptly notify the Borrower and all Lenders. Thereafter, the obligation of
the Lenders to make or maintain LIBO 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, conversion or
continuation of LIBO Rate Loans or,

                                       38
<PAGE>

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.

      SECTION 3.4 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 LIBO 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
3.1 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 LIBO Rate Loans, in the determination of the Adjusted LIBO 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 Agent), the
Borrower shall pay to such Lender such additional amounts as will compensate
such Lender for such reduction.

      SECTION 3.5 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); or

      (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 LIBO Rate Loan on a day other than the last day of
the Interest Period therefor as a result of a request by the Borrower pursuant
to Section 3.9;

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

                                       39
<PAGE>

For purposes of calculating amounts payable by the Borrower to the Lenders under
this Section 3.5, each Lender shall be deemed to have funded each LIBO Rate Loan
made by it at the LIBO Rate for such Loan by a matching deposit or other
borrowing in the applicable offshore Dollar interbank market for a comparable
amount and for a comparable period, whether or not such LIBO Rate Loan was in
fact so funded.

      SECTION 3.6 MATTERS APPLICABLE TO ALL REQUESTS FOR COMPENSATION.

      (a) A certificate of the Administrative Agent or any Lender claiming
compensation under this Article III and setting forth the additional amount or
amounts to be paid to it hereunder shall be conclusive in the absence of
manifest error. In determining such amount, the Administrative Agent or such
Lender may use any reasonable averaging and attribution methods.

      (b) Upon any Lender's making a claim for compensation under Section 3.1 or
3.4, the Borrower may remove or replace such Lender in accordance with Section
3.9; provided that the Borrower shall have the right to replace such Lender only
if they also replace any other Lender who has made or is making a similar claim
for compensation under Section 3.1 or 3.4.

      SECTION 3.7 SURVIVAL. All of the Borrower's obligations under this Article
III shall survive termination of the Commitments and of this Agreement and
payment in full of all the other Obligations.

      SECTION 3.8 FOREIGN LENDERS. Each Lender that is a "foreign corporation,
partnership or trust" within the meaning of the Code (a "Foreign Lender") shall
deliver to the Administrative Agent, prior to receipt of any payment subject to
withholding under the Code (or after accepting an assignment of an interest
herein), two duly signed completed copies of either IRS Form W-8BEN or any
successor thereto (relating to such Person and entitling it to an exemption
from, or reduction of, withholding tax on all payments to be made to such Person
by the Borrower pursuant to this Agreement) or IRS Form W-8ECI or any successor
thereto (relating to all payments to be made to such Person by the Borrower
pursuant to this Agreement) or such other evidence satisfactory to the Borrower
and the Administrative Agent that such Person is entitled to an exemption from,
or reduction of, U.S. withholding tax. Thereafter and from time to time, each
such Person shall (a) promptly submit to the Administrative Agent such
additional duly completed and signed copies of one of such forms (or such
successor forms as shall be adopted from time to time by the relevant United
States taxing authorities) as may then be available under then current United
States laws and regulations to avoid, or such evidence as is satisfactory to the
Borrower and the Administrative Agent of any available exemption from or
reduction of, United States withholding taxes in respect of all payments to be
made to such Person by the Borrower pursuant to this Agreement, (b) promptly
notify the 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 Person. If such Person fails to deliver the above forms or other
documentation, then the Administrative Agent may withhold from any interest
payment to such Person an amount equivalent to the applicable withholding tax
imposed by Sections 1441 and 1442 of the Code, without reduction. If any
Governmental Authority asserts that the Administrative Agent did not properly
withhold any tax or other amount from payments made in respect of such Person,
such Person shall indemnify the

                                       40
<PAGE>

Administrative Agent therefor, including all penalties and interest, any taxes
imposed by any jurisdiction on the amounts payable to the Administrative Agent
under this Section, and costs and expenses (including Attorney Costs) of the
Administrative Agent. The obligation of the Lenders under this Section shall
survive the payment of all Obligations and the resignation or replacement of the
Administrative Agent.

      SECTION 3.9 REMOVAL AND REPLACEMENT OF LENDERS.

      (a) Under any circumstances set forth herein providing that the Borrower
shall have the right to remove or replace a Lender as a party to this Agreement,
the Borrower may, upon notice to such Lender and the Administrative Agent, (i)
remove such Lender by terminating such Lender's Commitment or (ii) replace such
Lender by causing such Lender to assign its Commitment (without payment of any
assignment fee) pursuant to Section 10.7.2(a) 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 3.6(b), it shall be obligated to remove or replace, as the case may be,
all Lenders that have made similar requests for compensation pursuant to Section
3.1 or 3.4. The Borrower shall (x) pay in full all principal, interest, fees and
other amounts owing to such Lender through the date of termination or assignment
(including any amounts payable pursuant to Section 3.5), (y) provide appropriate
assurances and indemnities (which may include letters of credit) to the Issuing
Bank as may reasonably be required with respect to any continuing obligation to
purchase participation interests in any L/C Obligations then outstanding, and
(z) release such Lender from its obligations under the Loan Documents. Any
Lender being replaced shall execute and deliver an Lender Assignment with
respect to such Lender's Commitment and outstanding Credit Extensions. The
Administrative Agent shall distribute an amended Schedule 2.1, which shall be
deemed incorporated into this Agreement, to reflect changes in the identities of
the Lenders and adjustments of their respective Commitments and/or Percentage
Shares resulting from any such removal or replacement.

      (b) In order to make all the Lenders' interests in any outstanding Credit
Extensions ratable in accordance with any revised Percentage Shares after giving
effect to the removal or replacement of a Lender, the Borrower shall pay or
prepay, if necessary, on the effective date thereof, all outstanding Loans of
all Lenders, together with any amounts due under Section 3.5. The Borrower may
then request Loans from the Lenders in accordance with their revised Percentage

Extension.

                                   ARTICLE V.

necessary or required in connection with the execution, delivery or performance
by, or enforcement against, any Loan Party of this Agreement or any other Loan
Document.

      SECTION 5.4 BINDING EFFECT. This Agreement has been, and each other Loan
Document, when delivered hereunder, will have been, duly executed and delivered
by each Loan Party that is a party thereto. This Agreement constitutes, and each
other Loan Document when so delivered will constitute, a legal, valid and

any of its Subsidiaries or against any of their properties or revenues that (a)
purport to affect or pertain to this Agreement or any other Loan Document, or
any of the transactions contemplated hereby, or (b) if determined adversely,
could reasonably be expected to have a Material Adverse Effect.

      SECTION 5.7 NO DEFAULT. Neither the Borrower nor any Subsidiary is in
default under or with respect to any Contractual Obligation that could be
reasonably expected to have a Material Adverse Effect. No Default or Event of
Default has occurred and is continuing or would result from the consummation of

has good record and marketable title in fee simple to, or valid leasehold

of the Borrower and its Subsidiaries is subject to no Liens, other than Liens
permitted by Section 7.1.

      SECTION 5.9 ENVIRONMENTAL MATTERS. The Borrower and its Subsidiaries
conduct in the ordinary course of business a review of the effect of existing
Environmental Laws and claims alleging potential liability or responsibility for
violation of any Environmental Law on their respective businesses, operations
and properties, and as a result thereof the Borrower has reasonably concluded
that, except as would not have a Material Adverse Effect (or with respect to
(c), (d) and (e) below, where the failure to take such actions would not have a
Material Adverse Effect):

      (a) neither any property of any Loan Party or any Subsidiary, nor the
operations conducted thereon violate any Environmental Laws;

      (b) without limitation of clause (a) above, no property of any Loan Party
or any Subsidiary, nor the operations currently conducted thereon or, to the
best knowledge of the Borrower, by any prior owner or operator of such property

Borrower's knowledge, threatened action, suit, investigation, inquiry or
proceeding by or before any Governmental Authority or to any remedial
obligations under Environmental Laws;

substantial endangerment to public health or welfare or the environment, and, to
the best knowledge of the Borrower, all such transport carriers and treatment
and disposal facilities have been and are operating in compliance with
Environmental Laws and so as not to pose an imminent and substantial

subject of any existing, pending or, to the Borrower's knowledge, threatened
action, investigation or inquiry by any Governmental Authority in connection
with any Environmental Laws;

      (e) the Loan Parties and their Subsidiaries have taken all steps
reasonably necessary to determine and have determined that no Hazardous
Materials, solid waste, or oil and gas exploration and production wastes, have
been disposed of or otherwise released and there has been no threatened release

Subsidiary except, in each case, in compliance with Environmental Laws and so as
not to pose an imminent and substantial endangerment to public health or welfare
or the environment; and

Subsidiaries are insured with financially sound and reputable insurance
companies that are not Affiliates of the Borrower, in such amounts, with such
deductibles and covering such risks as are customarily carried by companies
engaged in similar businesses and owning similar properties in localities where
the Borrower or its Subsidiaries operate.

      SECTION 5.11 TAXES. The Borrower and its Subsidiaries have filed all
Federal, state and other material tax returns and reports required to be filed,
and have paid all Federal, state and other material taxes, assessments, fees and

income or assets otherwise due and payable, except those which are being
contested in good faith by appropriate proceedings and for which adequate
reserves have been provided in accordance with GAAP. There is no proposed tax
assessment against the Borrower or any Subsidiary that would, if made, have a
Material Adverse Effect.

      SECTION 5.12 ERISA COMPLIANCE.

applicable provisions of ERISA, the Code and other Federal or state Laws. Each
Plan that is intended to qualify under Section 401(a) of the Code has received a
favorable determination letter from the IRS or an application for such a letter
is currently being processed by the IRS with respect thereto and, to the best
knowledge of the Borrower, nothing has occurred which would prevent, or cause
the loss of, such qualification. The Borrower and each ERISA Affiliate of the
Borrower have made all required contributions to each Plan subject to Section
412 of the Code, and no application for a funding waiver or an extension of any
amortization period pursuant to Section 412 of the Code has been made with
respect to any Plan.

      (b) There are no pending or, to the best knowledge of the Borrower,
threatened claims, actions or lawsuits, or action by any Governmental Authority,

incurred, or reasonably expects to incur, any liability (and no event has

Multiemployer Plan; and (v) neither the Borrower nor any ERISA Affiliate of the
Borrower has engaged in a transaction that could be subject to Sections 4069 or

<PAGE>

      SECTION 5.13 SUBSIDIARIES.

      (a) The Borrower has no Subsidiaries other than those specifically
disclosed in Part (a) of Schedule 5.13. All Subsidiaries of Borrower are duly
organized, validly existing and in good standing under the laws of their
respective jurisdictions of organization and are duly qualified to do business
in each jurisdiction where failure to so qualify would have an Material Adverse
Effect. All outstanding shares of stock of each class of each Subsidiary of
Borrower have been and will be validly issued and are and will be fully paid and
nonassessable and are and will be owned, beneficially and of record, by Borrower
or a wholly-owned Subsidiary of Borrower free and clear of any Liens (other than
Liens permitted by Section 7.1).

      (b) Part (b) of Schedule 5.13 sets forth each of the Subsidiaries of the
Borrower that shall have delivered a Guaranty on the Closing Date. Each such
Guarantor is and will remain a wholly-owned Subsidiary of the Borrower.

      (c) The Borrower has no equity investments in any other corporation or
entity other than those specifically disclosed in Part (c) of Schedule 5.13.

      SECTION 5.14 MARGIN REGULATIONS; INVESTMENT COMPANY ACT; PUBLIC UTILITY
HOLDING COMPANY ACT.

      (a) The Borrower is not engaged and will not engage, principally or as one
of its important activities, in the business of purchasing or carrying margin
stock (within the meaning of Regulation U issued by the Board), or extending
credit for the purpose of purchasing or carrying margin stock.

      (b) None of the Borrower, any Person controlling the Borrower, or any
Subsidiary (i) is a "holding company," or a "subsidiary company" of a "holding
company," or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company," within the meaning of the Public Utility Holding Company
Act of 1935, or (ii) is or is required to be registered as an "investment
company" under the Investment Company Act of 1940.

      SECTION 5.15 DISCLOSURE. No statement, information, report,
representation, or warranty made in writing by any Loan Party in any Loan
Document or furnished to the Administrative Agent or any Lender by or on behalf
of any Loan Party in connection with any Loan Document contains any untrue
statement of a material fact or omits any material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. There is no fact known
to the Borrower which has caused, or which likely would in the future in the
reasonable judgment of the Borrower cause, a Material Adverse Effect (except for
any economic conditions which affect generally the industry in which the
Borrower and its Subsidiaries conduct business), that has not been set forth in
this Agreement or in the other documents, certificates, statements, reports and
other information furnished in writing to the Lenders by or on behalf of the
Borrower or any other Loan Party in connection with the transactions
contemplated hereby.

      SECTION 5.16 INTELLECTUAL PROPERTY; LICENSES, ETC. The Borrower and its
Subsidiaries own, or possess the right to use, all of the trademarks, service
marks, trade names, copyrights, patents, patent rights, franchises, licenses and
other rights that are reasonably necessary for the

                                       48
<PAGE>

operation of their respective businesses, without conflict with the rights of
any other Person. To the best knowledge of the Borrower, no slogan or other
advertising device, product, process, method, substance, part or other material
now employed, or now contemplated to be employed, by the Borrower or any
Subsidiary infringes upon any rights held by any other Person. No claim or
litigation regarding any of the foregoing is pending or, to the best knowledge
of the Borrower, threatened, and no patent, invention, device, application,
principle or any statute, law, rule, regulation, standard or code is pending or,
to the knowledge of the Borrower, proposed, which, in either case, could
reasonably be expected to have a Material Adverse Effect.

      SECTION 5.17 DIRECT BENEFIT. The initial Loans and Letters of Credit
hereunder and all additional Loans and Letters of Credit hereunder are for the
direct benefit of the Borrower, or in the case of any initial or additional
Letters of Credit, one or more of the Guarantors, and the initial Loans and
Letters of Credit hereunder are used to refinance and replace indebtedness
owning, directly or indirectly, by the Borrower and certain of the Guarantors to
the Lenders under the Existing Credit Facility. The Borrower and the Guarantors
are engaged as an integrated group in the business of oil and gas exploration
and related fields, and any benefits to the Borrower or any Guarantor is a
benefit to all of them, both directly or indirectly, inasmuch as the successful
operation and condition of the Borrower and the Guarantors is dependent upon the
continued successful performance of the functions of the integrated group as a
whole.

      SECTION 5.18 SOLVENCY. Each of the following is true for the Borrower,
each Guarantor and the Borrower and the Guarantors on a consolidated basis: (a)
the fair saleable value of its or their property is (i) greater than the total
amount of its liabilities (including contingent liabilities), and (ii) greater
than the amount that would be required to pay its probable aggregate liability
on its then existing debts as they become absolute and matured; (b) its or their
property is not unreasonable in relation to its business or any contemplated or
undertaken transaction; and (c) it or they do not intend to incur, or believe
that it or they will incur, debts beyond its or their ability to pay such debts
as they become due.

      SECTION 5.19 INDENTURE DEBT DOCUMENTS. Before and after giving effect to
all the Credit Extensions contemplated hereunder, all representations and
warranties of the Borrower or any Guarantor contained in any Indenture Debt
Document are true and correct in all material respects (except to the extent
such representations or warranties relate or refer to a specified, earlier
date). Before and after giving effect to all the Credit Extensions contemplated
hereunder, there is no event of default or event or condition that could become
an event of default with notice or lapse of time or both, under the Indenture
Debt Documents and each of the Indenture Debt Documents is in full force and
effect.

                                   ARTICLE VI.
                              AFFIRMATIVE COVENANTS

      So long as any Lender shall have any Commitment hereunder, any Loan or
other Obligation shall remain unpaid or unsatisfied, or any Letter of Credit
shall remain outstanding, the Borrower shall, and shall (except in the case of
the covenants set forth in Sections 6.1, 6.2, 6.3 and 6.11) cause each of its
Subsidiaries to:

                              ADMINISTRATIVE AGENT

      SECTION 9.1 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT.

      (a) Each Lender hereby irrevocably (subject to Section 9.9) appoints,
designates and authorizes the Administrative Agent to take such action on its
behalf under the provisions of this Agreement and each other Loan Document and
to exercise such powers and perform such duties as are expressly delegated to it
by the terms of this Agreement or any other Loan Document, together with such
powers as are reasonably incidental thereto. Notwithstanding any provision to
the contrary contained elsewhere herein or in any other Loan Document, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, nor shall the Administrative Agent have or be deemed
to have any fiduciary relationship with any Lender or participant, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent. Without limiting the
generality of the foregoing sentence, the use of the term "agent" herein and in
the other Loan Documents with reference to the Administrative Agent is not
intended to connote any fiduciary or other implied (or express) obligations
arising under agency doctrine of any applicable law. Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only
an administrative relationship between independent contracting parties. Each
Lender hereby agrees to assert no claim against the Administrative Agent on any
agency theory or any other theory of liability for breach of fiduciary duty, all
of which claims are hereby expressly waived by each Lender.

      (b) The Issuing Bank shall act on behalf of the Lenders with respect to
any Letters of Credit issued by it and the documents associated therewith until
such time (and except for so long) as the Administrative Agent may agree at the
request of the Majority Lenders to act for the Issuing Bank with respect
thereto; provided, however, that the Issuing Bank shall have all of the benefits
and immunities (i) provided to the Administrative Agent in this Article IX with
respect to any acts taken or omissions suffered by the Issuing Bank in
connection with Letters of Credit issued by it or proposed to be issued by it
and the application and agreements for letters of credit pertaining to the
Letters of Credit as fully as if the term "Administrative Agent" as used in this
Article IX included the

                                       66
<PAGE>

Issuing Bank with respect to such acts or omissions, and (ii) as additionally
provided herein with respect to the Issuing Bank.

      SECTION 9.2 DELEGATION OF DUTIES. The Administrative Agent may execute any
of its duties under this Agreement or any other Loan Document by or through
agents, employees or attorneys-in-fact and shall be entitled to advice of
counsel and other consultants or experts concerning all matters pertaining to
such duties. The Administrative Agent shall not be responsible for the
negligence or misconduct of any agent or attorney-in-fact that it selects in the
absence of gross negligence or willful misconduct.

      SECTION 9.3 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,
preliminary statement, statement, representation or warranty made by any Loan
Party or any officer thereof, contained herein or in any other Loan Document, or
in any certificate, report, statement or other document referred to or provided
for in, or received by the Administrative Agent under or in connection with,
this Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of any Loan Party or any other party to any Loan
Document to perform its obligations hereunder or thereunder. No Agent-Related
Person shall be under any obligation to any Lender or participant to ascertain
or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to
inspect the properties, books or records of any Loan Party or any Affiliate
thereof.

      SECTION 9.4 RELIANCE BY ADMINISTRATIVE AGENT.

      (a) The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, communication, signature, resolution,
representation, notice, consent, certificate, affidavit, letter, telegram,
facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons, and upon advice and statements of
legal counsel (including counsel to any Loan Party), independent accountants and
other experts selected by the Administrative Agent. The Administrative Agent
shall be fully justified in failing or refusing to take any action under any
Loan Document unless it shall first receive such advice or concurrence of the
Majority Lenders as it deems appropriate and, if it so requests, it shall first
be indemnified to its satisfaction by the Lenders against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. The Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement or any
other Loan Document in accordance with a request or consent of the Majority
Lenders or all the Lenders, if required hereunder, and such request and any
action taken or failure to act pursuant thereto shall be binding upon all the
Lenders and participants. Where this Agreement expressly permits or prohibits an
action unless the Majority Lenders otherwise determine, the Administrative Agent
shall, and in all other instances, the Administrative Agent may, but shall not
be required to, initiate any solicitation for the consent or a vote of the
Lenders.

                                       67
<PAGE>

      (b) For purposes of determining compliance with the conditions specified
in Section 4.1, 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 either sent by the Administrative Agent to such Lender for
consent, approval, acceptance or satisfaction, or required thereunder to be
consented to or approved by or acceptable or satisfactory to a Lender.

      SECTION 9.5 NOTICE OF DEFAULT. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default, except with respect to defaults in the payment of principal, interest
and fees required to be paid to the Administrative Agent for the account of the
Lenders, unless the Administrative Agent shall have received written notice from
a Lender or the Borrower referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default." The
Administrative Agent will notify the Lenders of its receipt of any such notice.
The Administrative Agent shall take such action with respect to such Default or
Event of Default as may be directed by the Majority Lenders in accordance with
Article VIII; provided, however, that unless and until the Administrative Agent
has received any such direction, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default or Event of Default as it shall deem advisable or in the best
interest of the Lenders.

      SECTION 9.6 CREDIT DECISION; DISCLOSURE OF INFORMATION BY ADMINISTRATIVE
AGENT. Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by the Administrative Agent
hereinafter taken, including any consent to and acceptance of any assignment or
review of the affairs of any Loan Party or any Affiliate thereof, shall be
deemed to constitute any representation or warranty by any Agent-Related Person
to any Lender as to any matter, including whether Agent-Related Persons have
disclosed material information in their possession. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Loan Parties and their respective Subsidiaries, and all
applicable bank or other regulatory Laws relating to the transactions
contemplated hereby, and made its own decision to enter into this Agreement and
to extend credit to the Borrower hereunder. Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Loan Documents, and to make
such investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and the other Loan Parties. Except for notices,
reports and other documents expressly required to be furnished to the Lenders by
the Administrative Agent herein, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, prospects, operations, property, financial
and other condition or creditworthiness of any of the Loan Parties or any of
their respective Affiliates which may come into the possession of any
Agent-Related Person.

      SECTION 9.7 INDEMNIFICATION OF ADMINISTRATIVE AGENT. Whether or not the
transactions contemplated hereby are consummated, the Lenders shall indemnify
upon demand each Agent-Related Person (to the extent not reimbursed by or on
behalf of any Loan Party and without limiting the obligation of any Loan Party
to do so), pro rata, and hold harmless each Agent-Related

                                       68
<PAGE>

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

      SECTION 9.8 ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. BMO 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 their respective Affiliates as though BMO were not the
Administrative Agent or the Issuing Bank hereunder and without notice to or
consent of the Lenders. The Lenders acknowledge that, pursuant to such
activities, BMO or its Affiliates may receive information regarding any Loan
Party or its Affiliates (including information that may be subject to
confidentiality obligations in favor of such Loan Party or such Affiliate) and
acknowledge that the Administrative Agent shall be under no obligation to
provide such information to them. With respect to its Loans, BMO 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 or the
Issuing Bank, and the terms "Lender" and "Lenders" include BMO in its individual
capacity.

      SECTION 9.9 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may
resign as Administrative Agent upon 30 days' notice to the Lenders. If the
Administrative Agent resigns under this Agreement, the Majority Lenders shall
appoint from among the Lenders a successor administrative agent for the Lenders.
If no successor administrative agent is appointed prior to the effective date of
the resignation of the Administrative Agent, the Administrative Agent may
appoint, after consulting with the Lenders, a successor administrative agent
from among the Lenders. Upon the acceptance of its appointment as successor
administrative agent hereunder, such successor administrative agent shall
succeed to all the rights, powers and duties of the retiring Administrative
Agent and the term "Administrative Agent" shall mean such successor
administrative agent and the retiring Administrative Agent's appointment, powers
and duties as Administrative Agent shall be terminated. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Article IX and Sections 10.4 and 10.5 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor administrative agent
has accepted appointment as Administrative Agent by the date which is 30 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders

                                       69
<PAGE>

shall perform all of the duties of the Administrative Agent hereunder until such
time, if any, as the Majority Lenders appoint a successor agent as provided for
above.

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

                                   ARTICLE X.
                                  MISCELLANEOUS

      SECTION 10.1 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 therefrom, shall be effective unless in
writing signed by the Majority Lenders and the Borrower and acknowledged and
agreed by each other Loan Party, and acknowledged by the Administrative Agent,
and each such waiver or consent shall be effective only in the specific instance
and for the specific purpose for which given; provided, however, that no such
amendment, waiver or consent shall, unless in writing and signed by each of the
Lenders directly affected thereby and by the Borrower, and acknowledged and
agreed by each other Loan Party and acknowledged by the Administrative Agent, do
any of the following:

      (a) extend or increase the Commitment of any Lender (or reinstate any
Commitment terminated pursuant to Section 8.2);

      (b) postpone any date fixed by this Agreement or any other Loan Document
for any payment or mandatory prepayment of principal, interest, fees or other
amounts due to the Lenders (or any of them) hereunder or under any other Loan
Document;

      (c) 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

Commitment Fee Rate that would result in a reduction of any interest rate on any
Loan;

      (d) change the percentage of the Aggregate Commitments or of the aggregate
unpaid principal amount of the Loans and L/C Obligations which is required for
the Lenders or any of them to take any action hereunder;

      (e) increase the Borrowing Base, or take any other action which requires
the signing of all the Lenders pursuant to the terms of this Agreement or of any
other Loan Document, or change the Percentage Share or Voting Percentage of any
Lender; or

      (f) amend this Section, or Section 2.14, or any provision herein providing
for consent or other action by all the Lenders; or

                                       70
<PAGE>

      (g) permit any termination, amendment, modification, waiver, or release of
any Guaranty or any provision thereof; or

      (h) release any collateral under any of the Security Documents, or permit
any termination, amendment, modification, waiver or release of any Security
Document or an provision thereof, provided that, notwithstanding the foregoing,
the consent of the Lenders shall not be required for any release of any
collateral under any of the Security Documents in connection with a Disposition
by the Borrower or any Guarantor if such Disposition is permitted by Section 7.5
hereof as Section 7.5 is in effect on the Closing Date;

and, provided further, that (i) no amendment, waiver or consent shall, unless in
writing and signed by the Issuing Bank in addition to the Majority Lenders or
all the Lenders, as the case may be, affect the rights or duties of the Issuing
Bank 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 the Administrative Agent in
addition to the Majority Lenders or all the Lenders, as the case may be, affect
the rights or duties of the Administrative Agent under this Agreement or any
other Loan Document; and (iii) the Agent and Arranger Fee Letter may be amended,
or rights or privileges thereunder waived, in a writing executed only by the
parties thereto.

      SECTION 10.2 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) and mailed, faxed or delivered, to the address,
facsimile number or (subject to subsection (c) below) electronic mail address
specified for notices on Schedule 10.2; or, in the case of the Borrower, the
Administrative Agent, or the Issuing Bank, to such other address as shall be
designated by such party in a notice to the other parties, and in the case of
any other party, to such other address as shall be designated by such party in a
notice to the Borrower, the Administrative Agent and the Issuing Bank. All such
notices and other communications shall be deemed to be given or made upon the

delivered by hand or by courier, when signed for by the intended recipient; (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 the Administrative Agent and
the Issuing Bank pursuant to Article II shall not be effective until actually
received by such Person. Any notice or other communication permitted to be
given, made or confirmed by telephone hereunder shall be given, made or
confirmed by means of a telephone call to the intended recipient at the number
specified on Schedule 10.2, it being understood and agreed that a voicemail
message shall in no event be effective as a notice, communication or

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

                                       71
<PAGE>

      (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, annual and quarterly compliance information and other
information, and to distribute Loan Documents for execution by the parties
thereto, and may not be used for any other purpose.

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

      SECTION 10.3 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or
the Administrative Agent to exercise, and no delay by any such Person in
exercising, any right, remedy, power or privilege hereunder shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, remedy,
power or privilege hereunder preclude any other or further exercise thereof or
the exercise of any other right, remedy, power or privilege. The rights,
remedies, powers and privileges herein or therein provided are cumulative and
not exclusive of any rights, remedies, powers and privileges provided by law.

      SECTION 10.4 ATTORNEY COSTS, EXPENSES AND TAXES. The Borrower agrees (a)
to pay or reimburse the Administrative 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 (b) to pay or reimburse the
Administrative Agent and each Lender for all costs and expenses incurred in
connection with the enforcement, attempted enforcement, or preservation of any
rights or 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 the Administrative Agent and the cost of
independent public accountants and other outside experts retained by the
Administrative Agent or any Lender. The agreements in this Section shall survive
the termination of the Commitments and repayment of all the other Obligations.

      SECTION 10.5 INDEMNIFICATION BY THE BORROWER. Whether or not the
transactions contemplated hereby are consummated, the Borrower agrees to
indemnify, defend, save 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: (a) any
and all claims, demands, actions or causes of action that are asserted against
any Indemnitee by any Person (other than the Administrative Agent or any Lender)
relating directly or indirectly to a claim, demand, action or cause of action
that such Person asserts or may assert against any Loan

                                       72
<PAGE>

Party, any Affiliate of any Loan Party or any of their respective officers or
directors; (b) any and all claims, demands, actions or causes of action that may
at any time (including at any time following repayment of the Obligations and
the resignation or removal of the Administrative Agent or the replacement of any
Lender) be asserted or imposed against any Indemnitee, arising out of or
relating to, the Loan Documents, any predecessor loan documents, the
Commitments, the use or contemplated use of the proceeds of any Credit
Extension, or the relationship of any Loan Party, the Administrative Agent and
the Lenders under this Agreement or any other Loan Document; (c) any
administrative or investigative proceeding by any Governmental Authority arising
out of or related to a claim, demand, action or cause of action described in
subsection (a) or (b) above; and (d) any and all liabilities (including
liabilities under indemnities), losses, costs or expenses (including Attorney
Costs) that any Indemnitee suffers or incurs as a result of the assertion of any
foregoing claim, demand, action, cause of action, litigation or proceeding, or
as a result of the preparation of any defense in connection with any foregoing
claim, demand, action, cause of action, litigation or proceeding, in all cases,
WHETHER OR NOT ARISING OUT OF THE NEGLIGENCE OF AN INDEMNITEE, and whether or
not an Indemnitee is a party to such claim, demand, action, cause of action,
litigation or proceeding (all the foregoing, collectively, the "Indemnified
Liabilities"); provided that no Indemnitee shall be entitled to indemnification
for any claim caused by its own gross negligence or willful misconduct or for
any loss asserted against it by another Indemnitee. The agreements in this
Section shall survive the termination of the Commitments and repayment of all
the other Obligations.

      SECTION 10.6 PAYMENTS SET ASIDE. To the extent that the Borrower makes a
payment to the Administrative Agent or any Lender, or the Administrative Agent
or any Lender exercises its right of set-off, and such payment or the proceeds
of such set-off or any part thereof is subsequently invalidated, declared to be
fraudulent or preferential, set aside or required (including pursuant to any
settlement entered into by the Administrative Agent or such Lender in its
discretion) to be repaid to a trustee, receiver or any other party, in
connection with any proceeding under any Debtor Relief Law or otherwise, then
(a) to the extent of such recovery, the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Lender severally agrees to pay to the Administrative Agent upon demand its
applicable share of any amount so recovered from or repaid by the Administrative
Agent, plus interest thereon from the date of such demand to the date such
payment is made at a rate per annum equal to (i) with respect to the first two
Business Days following such demand, the Federal Funds Rate from time to time in
effect, and (2) with respect to each day thereafter, the Base Rate from time to
time in effect.

      SECTION 10.7 SUCCESSORS AND ASSIGNS; ASSIGNMENTS; PARTICIPATIONS.

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

      10.7.2 Assignments.

                                       73
<PAGE>

      (a) Any Lender may assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans (including in all instances for purposes
of this subsection (a), 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, the aggregate amount of the Commitment (which for this purpose includes
Loans outstanding thereunder, including as noted above, participations in L/C
Obligations) subject to each such assignment, determined as of the date the
Lender Assignment with respect to such assignment is delivered to the
Administrative Agent, shall not be less than $5,000,000 unless each of the
Administrative Agent and, so long as no Default has occurred and is continuing
and so long as in the case of Bank of Montreal, such Lender shall have been
reduced to its "final hold amount" as described in the commitment letter
referred to in the Agent and Arranger Fee Letter, 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 Borrowings on a non-pro rata basis, (iii) the parties
to each assignment shall execute and deliver to the Administrative Agent a
Lender Assignment, together with a processing and recordation fee of $3,500.
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 Lender Assignment, the Eligible Assignee thereunder shall be a party
hereto and, to the extent of the interest assigned by such Lender Assignment,
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 Lender Assignment, be released from its obligations under this Agreement
(and, in the case of an Lender Assignment covering all of the assigning Lender's
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of Sections 3.7,
10.4 and 10.5). Upon request, the Borrower (at its expense) shall execute and
deliver new or replacement Notes to the assigning Lender and the assignee
Lender. Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this subsection shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with subsection (d) of this Section.

      (b) 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 Lender Assignment delivered to it and a register for the recordation of the
names and addresses of the Lenders, and the Commitments of, and principal amount
of the Loans 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.

      10.7.3 Participations.

      (a) Any Lender may, without the consent of, or notice to, the Borrower or
the Administrative Agent, sell participations to one or more banks or other
entities (a "Participant") in all

                                       74
<PAGE>

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 Administrative Agent
and the other Lenders shall continue to deal solely and directly with such
Lender in connection with such Lender's rights and obligations under this
Agreement. Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, waiver or other modification that would (i) postpone any date
upon which any payment of money is scheduled to be paid to such Participant,
(ii) reduce the principal, interest, fees or other amounts payable to such
Participant, or (iii) release any Guarantor from the Guaranty. Subject to
subsection (e) of this Section, the Borrower agrees that each Participant shall
be entitled to the benefits of Sections 3.1, 3.4 and 3.5 to the same extent as
if it were a Lender and had acquired its interest by assignment pursuant to
subsection (b) of this Section. To the extent permitted by law, each Participant
also shall be entitled to the benefits of Section 10.9 as though it were a
Lender, provided such Participant agrees to be subject to Section 2.14 as though
it were a Lender.

      (b) A Participant shall not be entitled to receive any greater payment
under Section 3.1 or 3.4 than the applicable Lender would have been entitled to
receive with respect to the participation sold to such Participant, unless the
sale of the participation to such Participant is made with the Borrower's prior
written consent. A Participant that would be a Foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 3.1 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 3.8 as though it
were a Lender.

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

      10.7.5 Consent to Assignment. If the consent of the Borrower to an
assignment or to an Eligible Assignee is required hereunder (including a consent
to an assignment which does not meet the minimum assignment threshold specified
in clause (i) of the proviso to the first sentence of Section 10.7.2, the
Borrower shall be deemed to have given its consent five Business Days after the
date notice thereof has been delivered by the assigning Lender (through the
Administrative Agent) unless such consent is expressly refused by the Borrower
prior to such fifth Business Day.

      10.7.6 Definitions for Section 10.7. As used herein, the following terms
have the following meanings:

            "Eligible Assignee" means (a) a Lender; (b) an Affiliate of a
            Lender; and (c) any other Person (other than a natural Person)
            approved by the Administrative Agent, the Issuing Bank, and, after
            Bank of Montreal shall have assigned a sufficient amount of its
            Commitment (as set

                                       75
<PAGE>

            forth in Schedule 2.1) to one or more Persons (who shall become
            Lenders) such that Bank of Montreal's Commitment has been reduced to
            an amount not exceeding the "final hold amount" set forth in the
            commitment letter referred to in the Agent and Arranger Fee Letter,
            and provided that no Default has occurred and is continuing, the
            Borrower (each such approval not to be unreasonably withheld or
            delayed).

            "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.

      10.7.7 Assignment by BMO. Notwithstanding anything to the contrary
contained herein, if at any time BMO assigns all of its Commitment and Loans
pursuant to subsection (b) above, BMO may, upon 30 days' notice to the Borrower
and the Lenders, resign as Issuing Bank. In the event of any such resignation as
Issuing Bank, the Borrower shall be entitled to appoint from among the Lenders a
successor Issuing Bank hereunder; provided, however, that no failure by the
Borrower to appoint any such successor shall affect the resignation of BMO as
Issuing Bank. BMO shall retain all the rights and obligations of the Issuing
Bank hereunder with respect to all Letters of Credit outstanding as of the
effective date of its resignation as Issuing Bank and all L/C Obligations with
respect thereto (including the right to require the Lenders to make Base Rate
Loans or fund participations in Unreimbursed Amounts pursuant to Section 2.3.3).

      SECTION 10.8 CONFIDENTIALITY. (a) Each of the Administrative Agent 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'
directors, officers, employees and agents, including accountants, legal counsel
and other advisors (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; (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 any suit, action or proceeding relating to this Agreement or the enforcement
of rights hereunder; (f) subject to an agreement containing provisions
substantially the same as those of this Section, to (i) any Eligible Assignee of
or Participant in, or any prospective Eligible Assignee of or Participant in,
any of its rights or obligations under this Agreement 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 the Borrower;
(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 the Administrative 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.
For the purposes of this Section, "Information" means all information received
from the Borrower relating to the Borrower or its business, other than any such
information that is available to the Administrative Agent or any Lender on a
nonconfidential basis prior to disclosure by the Borrower; provided that, in the
case of information received from the Borrower

                                       76
<PAGE>

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.

      SECTION 10.9 SET-OFF. In addition to any rights and remedies of the
Lenders provided by law, upon the occurrence and during the continuance of any
Event of Default, each Lender is authorized at any time and from time to time,
without prior notice to the 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, now or hereafter existing, irrespective of
whether or not the Administrative Agent or such Lender shall have made demand
under this Agreement or any other Loan Document and although such Obligations
may be contingent or unmatured. Each Lender agrees promptly to notify the
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.

      SECTION 10.10 INTEREST RATE LIMITATION. It is the intention of the parties
hereto to conform strictly to applicable usury laws and, anything herein to the
contrary notwithstanding, the obligations of the Borrower to each Lender and the
Issuing Bank under this Agreement shall be subject to the limitation that
payments of interest shall not be required to the extent that receipt thereof
would be contrary to provisions of law applicable to such Lender or the Issuing
Bank limiting rates of interest which may be charged or collected by such Lender
or the Issuing Bank. Accordingly, if the transactions contemplated hereby would
be usurious under applicable law (including the Federal and state laws of the
United States of America, or of any other jurisdiction whose laws may be
mandatorily applicable) with respect to a Lender or the Issuing Bank then, in
that event, notwithstanding anything to the contrary in this Agreement, it is
agreed as follows: (i) the provisions of this Section 10.10 shall govern and
control; (ii) the aggregate of all consideration which constitutes interest
under applicable law that is contracted for, charged or received under this
Agreement, or under any of the other aforesaid agreements or otherwise in
connection with this Agreement by such Lender or the Issuing Bank shall under no
circumstances exceed the maximum amount of interest allowed by applicable law
(such maximum lawful interest rate, if any, with respect to such Lender or the
Issuing Bank herein called the "Highest Lawful Rate"), and any excess shall be
credited to the Borrower by such Lender or the Issuing Bank (or, if such
consideration shall have been paid in full, such excess promptly refunded to the
Borrower); (iii) all sums paid, or agreed to be paid, to the Lender or the
Issuing Bank for the use, forbearance and detention of the indebtedness of the
Borrower to such Lender or the Issuing Bank hereunder shall, to the extent
permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of such indebtedness until payment in full so that the
actual rate of interest is uniform throughout the full term thereof; and (iv) if
at any time the interest provided pursuant to Article II together with any other
fees payable pursuant to this Agreement and deemed interest under applicable
law, exceeds that amount which would have accrued at the Highest Lawful Rate,
the amount of interest and any such fees to accrue to such Lender or the Issuing
Bank pursuant to this Agreement shall be limited, notwithstanding anything to
the contrary in this Agreement to that amount which would have accrued at the
Highest Lawful Rate, but any subsequent reductions, as applicable, shall not
reduce the interest

                                       77
<PAGE>

to accrue to such Lender or the Issuing Bank pursuant to this Agreement below
the Highest Lawful Rate until the total amount of interest accrued pursuant to
this Agreement and such fees deemed to be interest equals the amount of interest
which would have accrued to such Lender or the Issuing Bank if a varying rate
per annum equal to the interest provided pursuant to Article II had at all times
been in effect, plus the amount of fees which would have been received but for
the effect of this Section 10.10. For purposes of Tex. Fin. Code Ann. Ch. 303,
as amended, to the extent, if any, applicable to a Lender or the Issuing Bank,
the Borrower agrees that the Highest Lawful Rate shall be the "weekly ceiling"
as defined in said Article, provided that such Lender and the Issuing Bank may
also rely, to the extent permitted by applicable laws, on alternative maximum
rates of interest under other laws applicable to such Lender or such Issuer, as
the case may be, if greater. Tex. Fin. Code Ann. Ch. 346 (which regulates
certain revolving credit loan accounts and revolving tri-party accounts) shall
not apply to this Agreement or the Notes.

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

      SECTION 10.12 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All
representations and warranties made hereunder and in any other Loan Document or
other document delivered pursuant hereto or thereto or in connection herewith or
therewith shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by the
Administrative Agent and each Lender, regardless of any investigation made by
the Administrative Agent or any Lender or on their behalf and notwithstanding
that the Administrative Agent or any Lender may have had notice or knowledge of
any Default or Event of Default at the time of any Credit Extension, and shall
continue in full force and effect as long as any Loan or any other Obligation
shall remain unpaid or unsatisfied or any Letter of Credit shall remain
outstanding.

      SECTION 10.13 COLLATERAL MATTERS; HEDGES. The benefit of the Security
Documents and the provisions of this Agreement and the other Loan Documents
relating to the collateral shall also extend to and be available on a pro rata
basis to each Lender and such Lender's Affiliates in respect of any obligations
under a Hedging Agreement only so long as such Lender remains a party to this
Agreement and this Agreement remains in effect. No Lender or Affiliate of a
Lender shall have any voting or consent right under any Loan Document as a
result of the existence of obligations owed to it under a Hedging Agreement.

      SECTION 10.14 RENEWAL AND CONTINUATION OF EXISTING INDEBTEDNESS. Upon the
effectiveness of this Agreement, all of the Existing Indebtedness outstanding on
such date shall hereby be restructured, rearranged, renewed, extended and
continued as provided in this Agreement and all Loans outstanding under the
Existing Credit Facility shall become Loans outstanding hereunder.

      In connection herewith, the Prior Lenders have sold, assigned, transferred
and conveyed, and Lenders party to this Agreement have purchased and accepted,
and hereby purchase and accept, so much of the Existing Indebtedness such that
each Lender's percentage of the loans and obligations outstanding pursuant to
the Existing Credit Facility, as restructured, rearranged, renewed, extended and
continued pursuant to this Agreement, shall be equal to such Lender's Percentage
Share upon the effectiveness of this Agreement. The Lenders acknowledge and
agree that the assignment, transfer and conveyance of the Existing Indebtedness
is without recourse to the Prior Lenders and without

                                       78
<PAGE>

any warranties whatsoever by any Prior Lender, except as expressly set forth in
the Assignment of Secured Indebtedness, the Mortgage Assignment and Amendment or
the Subordinate Mortgage Amendment.

      SECTION 10.15 SEVERABILITY. Any provision of this Agreement and the other
Loan Documents to which the Borrower is a party that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions thereof, and any such prohibition or unenforceability in
any jurisdiction shall not invalidate or render unenforceable such provision in
any other jurisdiction.

      SECTION 10.16 GOVERNING LAW.

      (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH,
THE LAW OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE
PERFORMED ENTIRELY WITHIN SUCH STATE (WITHOUT GIVING EFFECT TO THE PRINCIPLES
THEREOF RELATING TO CONFLICT OF LAW EXCEPT SECTION 5-1401 OF THE NEW YORK
GENERAL OBLIGATIONS LAW); PROVIDED THAT THE ADMINISTRATIVE AGENT AND EACH LENDER
SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

      (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK
SITTING IN MANHATTAN OR OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF SUCH
STATE, AND BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE BORROWER, THE
ADMINISTRATIVE AGENT AND EACH LENDER CONSENTS, FOR ITSELF AND IN RESPECT OF ITS
PROPERTY, TO THE NON-EXCLUSIVE JURISDICTION OF THOSE COURTS. THE BORROWER, THE
ADMINISTRATIVE AGENT AND EACH LENDER IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING
ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON
CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY ACTION OR
PROCEEDING IN SUCH JURISDICTION IN RESPECT OF ANY LOAN DOCUMENT OR OTHER
DOCUMENT RELATED THERETO. THE BORROWER, THE ADMINISTRATIVE AGENT AND EACH LENDER
WAIVES PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH MAY BE
MADE BY ANY OTHER MEANS PERMITTED BY THE LAW OF SUCH STATE.

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

                                       79
<PAGE>

WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO
THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

      SECTION 10.18 CONSENTS TO RENEWALS, MODIFICATIONS AND OTHER ACTIONS AND
EVENTS. This Agreement and all of the obligations of the Borrower hereunder
shall remain in full force and effect without regard to and shall not be
released, affected or impaired by: (a) any amendment, assignment, transfer,
modification of or addition or supplement to the Lenders Obligations, this
Agreement, any Note or any other Loan Document; (b) any extension, indulgence,
increase in the Lenders Obligations or other action or inaction in respect of
any of the Loan Documents or otherwise with respect to the Lenders Obligations,
or any acceptance of security for, or guaranties of, any of the Lenders
Obligations or Loan Documents, or any surrender, release, exchange, impairment
or alteration of any such security or guaranties including without limitation
the failing to perfect a security interest in any such security or abstaining
from taking advantage or of realizing upon any guaranties or upon any security
interest in any such security; (c) any default by the Borrower under, or any
lack of due execution, invalidity or unenforceability of, or any irregularity or
other defect in, any of the Loan Documents; (d) any waiver by the Lenders or any
other Person of any required performance or otherwise of any condition precedent
or waiver of any requirement imposed by any of the Loan Documents, any
guaranties or otherwise with respect to the Lenders Obligations; (e) any
exercise or non-exercise of any right, remedy, power or privilege in respect of
this Agreement or any of the other Loan Documents; (f) any sale, lease, transfer
or other disposition of the assets of the Borrower or any consolidation or
merger of the Borrower with or into any other Person, corporation, or entity, or
any transfer or other disposition by the Borrower or any other holder of any
shares of capital stock or other ownership interest of the Borrower; (g) any
bankruptcy, insolvency, reorganization or similar proceedings involving or
affecting the Borrower; (h) the release or discharge of the Borrower from the
performance or observance of any agreement, covenant, term or condition under
any of the Obligations or contained in any of the Loan Documents by operation of
law; or (i) any other cause whether similar or dissimilar to the foregoing
which, in the absence of this provision, would release, affect or impair the
Obligations, covenants, agreements and duties of the Borrower hereunder,
including without limitation any act or omission by the Administrative Agent, or
the Lenders or any other Person which increases the scope of the Borrower's
risk; and in each case described in this paragraph whether or not the Borrower
shall have notice or knowledge of any of the foregoing, each of which is
specifically waived by the Borrower. The Borrower warrants to the Administrative
Agent and the Lenders that it has adequate means to obtain from the Guarantors
on a continuing basis information concerning the financial condition and other
matters with respect to the Guarantors and it is not relying on the
Administrative Agent or the Lenders to provide such information either now or in
the future.

DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

                         EXECUTIVE EMPLOYMENT AGREEMENT

         This EXECUTIVE EMPLOYMENT AGREEMENT (this "Agreement") is made and
entered into by and between Texas Capital Bancshares, Inc. (the "Company"),
having a business address at 2100 McKinney, Suite 900, Dallas, Texas 75201 and
Peter Bartholow ("Executive").

                                    RECITALS

         The Board of Directors of the Company (the "Board of Directors") has
determined that it is in the best interests of the Company to employ Executive
and to reinforce and encourage the continued attention and dedication of members
of the Company's management, including the Executive, to their assigned duties
without distraction in potentially disturbing circumstances arising from the
possibility of a change in the control of the Company or the assertion of claims
and actions against employees.

         The Company wishes to assure itself of the services of the Executive
for the period provided in this Agreement and the Executive wishes to serve in
the employ of the Company on the terms and conditions hereinafter provided.

                                    AGREEMENT

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. EMPLOYMENT. Upon the terms and subject to the conditions contained
in this Agreement, the Executive agrees to provide full-time services for the
Company during the Employment Term. The Executive agrees to devote his best
efforts to the business of the Company, and shall perform his duties in a
diligent, trustworthy, and business-like manner, all for the purpose of
advancing the business of the Company. The Executive agrees to devote his entire
business time, attention, skill and energy exclusively to the business of the
Company. The Executive is encouraged to engage in appropriate civic, charitable
or religious activities and devote a reasonable amount of time to private
investments or boards or other activities provided that such activities do not
interfere or conflict with the Executive's responsibilities and are not and are
not likely to be contrary to the Company's interests.

         2. DUTIES. The duties of the Executive shall be those duties which can
reasonably be expected to be performed by a person with the title of Executive
Vice President and Chief Financial Officer and such other duties as may
otherwise be directed from time to time by the Chairman/Chief Executive Officer
or the Board of Directors. The Executive will comply with the lawful policies
and standards that the Company may establish or modify from time to time.

         3. EMPLOYMENT TERM. Subject to the terms and conditions hereof, the
Company agrees to employ the Executive for a term commencing on October 6, 2003
(the "Effective Date") and continuing through October 6, 2005 (the "Employment
Term"), unless otherwise terminated as set forth herein or renewed with the
written agreement of both parties hereto before the expiration hereof.

                                       1
<PAGE>
         4. SALARY AND BENEFITS.

                  (a) Base Salary. The Company shall, during the Employment
         Term, pay the Executive a base salary of at least $250,000.00 per year,
         payable in accordance with the Company's regular payroll practice in
         effect from time to time, less applicable withholding and payroll
         deductions. The Company agrees to consider increasing such base salary
         at least annually during the Employment Term, but shall not be
         obligated to effectuate such an increase.

                  (b) Bonus. During the Employment Term, the Executive will be
         included in the Executive Bonus Plan adopted and revised from time to
         time by the Board of Directors. The Company will pay Executive a bonus
         of $50,000.00 on March 31, 2004 and a bonus of $50,000.00 on September
         30, 2004, provided Executive is actively employed with the Company on
         the date of payment.

                  (c) Equity Compensation. Concurrently with the execution of
         this Agreement, the Executive shall receive a restricted stock award
         under the Company's 1999 Omnibus Stock Plan upon the terms and
         conditions set forth in Attachment A to this Agreement, which is hereby
         incorporated herein by reference, and an award of 50,000 stock options,
         which shall be subject to annual vesting based on a five (5)-year
         graded vesting schedule. During the Employment Term, the Executive will
         be eligible to receive, at the discretion of the Board of Directors,
         grants of stock options under the Plan.

                  (d) Employee Benefits and Perquisites. The Executive shall be
         entitled to participate in the employee benefit programs and receive
         other perquisites generally available to employees of the Company
         holding positions similar to the Executive.

         5. TERMINATION OF EMPLOYMENT. The Board of Directors of the Company or
the Executive may terminate the employment of the Executive at any time subject
to the provisions of this Section 5.

                  (a) Voluntary Resignation or Termination for Cause. If the
         Executive shall voluntarily terminate his employment for other than
         Good Reason, or if the Company shall terminate the employment of the
         Executive for Cause, the Employment Term shall terminate immediately
         and the Company shall have no further obligation to make any payment
         under this Agreement other than Executive's salary through the
         termination date. Notwithstanding the foregoing, with respect to any
         stock options or other plans or programs in which the Executive is
         participating at the time of termination of his employment, the
         Executive's rights and benefits under each such plan shall be
         determined in accordance with the terms, conditions, and limitations of
         the plan and any separate agreement executed by the Executive which may
         then be in effect.

                                       2

         If Executive resigns his employment without Good Reason prior to
         October 6, 2004, Executive shall pay the Company the sum of $62,500
         within thirty (30) days of the termination date.

         For the purposes of this Agreement, the Company shall have "Cause" to
         immediately terminate the Executive's employment hereunder upon (i) the
         continued failure by the Executive after notice to perform his duties
         with the Company (other than any such failure resulting from death or
         incapacity due to physical or mental illness), (ii) a conviction of, or
         a plea of "guilty" or "no contest" to, a felony or a crime involving
         dishonesty or a breach of trust, (iii) an act or omission that
         constitutes gross misconduct or moral turpitude, (iv) a breach of any
         duty owed to the Company, including but not limited to the duties of
         loyalty and confidentiality that is injurious to the Company, or (v)
         engaging in an act of fraud or misappropriation against the Company.

                  (b) Termination Without Cause; Resignation for Good Reason. If
         during the term of this Agreement, the Executive's employment is
         terminated by the Company without Cause or the Executive voluntarily
         terminates his employment for Good Reason, and the Executive executes a
         Release of any and all claims relating to or arising from his
         employment that he may have against the Company Group (as defined in
         Section 7 below) or any officer, director, agent, or employee of any
         entity that is part of the Company Group based on any act or omission
         through the date Executive's employment terminates ("Date of
         Termination"):

                           (i) The Company shall increase the annual
                  compensation of the Executive to the "adjusted compensation"
                  as defined herein and shall continue to pay such adjusted
                  compensation through the end of the Employment Term.

                           (ii) The Company shall maintain in full force and
                  effect for the continued benefit of the Executive, for a one
                  year period after the Date of Termination, all health
                  insurance benefits provided that his continued participation
                  is possible under the general terms and provisions of such
                  health insurance plans and programs.

                  For purposes of this Agreement, "Good Reason" shall mean:

                           (A) Without his express written consent, the
                  assignment of Executive to a position organizationally or
                  functionally inferior to his position with the Company on the
                  date of this Agreement;

                           (B) Without his express written consent, a reduction
                  by the Company in the Executive's base salary as in effect on
                  the date hereof, unless such reduction is a proportionate
                  reduction of the compensation of the Executive and all other
                  senior officers of the Company as a part of a Company-wide
                  effort to enhance the financial condition of the Company;

                                       3
<PAGE>

                           (C) Without his express written consent, the
                  Company's requiring the Executive to be based anywhere other
                  than the Dallas/Fort Worth Metroplex, except for required
                  travel on the Company's business;

                           (D) The failure by the Company to continue to allow
                  Executive to be eligible to participate in any stock option
                  plan in which the Executive is participating (or plans
                  providing substantially similar benefits) without the
                  Executive's consent.

                  For purposes of this Agreement, "adjusted compensation" shall
                  mean the annual base salary of Executive then in effect, plus
                  the bonus paid to Executive for the preceding calendar year,
                  multiplied by 150%.

                  (c) Death or Disability. The Company may terminate the
         Executive's employment upon the death or Disability of the Executive.
         As used herein, "Disability" means an illness or other disability which
         prevents the Executive from discharging his responsibilities under this
         Agreement for a period of 180 calendar days during any calendar year
         during the Employment Term, as determined in good faith by the Board of
         Directors. If the Company terminates the Executive's employment upon
         the death or Disability of the Executive, the Company shall continue to
         pay the Executive or his estate the base salary that would have been
         due through the first anniversary of the Date of Termination.

                  (d) Notice of Termination. Any termination of this Agreement
         by the Company for Cause, without Cause or as a result of the
         Executive's Disability, or by the Executive for Good Reason, shall be
         communicated by Notice of Termination to the other party hereto given
         in accordance with this Agreement. For purposes of this Agreement, a
         "Notice of Termination" means a written notice which (i) indicates the
         specific termination provision in this Agreement relied upon and (ii)
         specifies the Date of Termination, if such date is other than the date
         of receipt of such notice.

         6. CHANGE IN CONTROL.

                  (a) For purposes of this Agreement, a "Change in Control" of
         the Company shall be deemed to have occurred at such time as:

                           (i) any "person" (as the term is used in Sections
                  13(d) and 14(d) of the Exchange Act) is or becomes the
                  "beneficial owner" (as defined in Rule 13d-3 under the
                  Exchange Act), directly or indirectly, of voting securities of
                  the Company representing 25% or more of the Company's
                  outstanding voting securities or rights to acquire such
                  securities except for any voting securities issued or
                  purchased under any employee benefit plan of the Company or
                  its Subsidiaries; or

                           (ii) individuals who constitute the Board of
                  Directors on the date hereof (the "Incumbent Board") cease for
                  any reason to constitute at least a majority thereof, provided
                  that any person becoming a director subsequent to the

                                       4
<PAGE>

                  date hereof whose election was approved by a vote of at least
                  three-quarters of the directors comprising the Incumbent
                  Board, or whose nomination for election by the Company's
                  stockholders was approved by a Nominating Committee solely
                  composed of members which are Incumbent Board members, shall
                  be, for purposes of this clause (ii), considered as though he
                  were a member of the Incumbent Board; or

                           (iii) a plan of reorganization, merger,
                  consolidation, sale of all or substantially all of the assets
                  of the Company or similar transaction occurs or is effectuated
                  in which the Company is not the resulting entity; provided,
                  however, that such an event listed above will be deemed to
                  have occurred or to have been effectuated upon receipt of all
                  required regulatory approvals not including the lapse of any
                  required waiting periods; or

                           (iv) the Board of Directors determines in its sole
                  discretion that a Change in Control has occurred.

         (b) If, during the Employment Term, a Change in Control occurs, then
(i) the Executive shall be entitled to the benefits provided in paragraphs (c)
and (d) of this Section 6 upon (I) the termination of the Executive's employment
by the Company without Cause after the occurrence of such Change of Control, or
(II) the termination of the Executive's employment by the Executive for Good
Reason after the occurrence of such Change of Control; and (ii) the Executive
shall be entitled to the benefits provided in paragraph (e) of this Section 6.

         (c) Upon the Executive's entitlement to benefits pursuant to Section
6(b), the Company shall pay Executive, as liquidated damages in place of any
amounts otherwise payable to the Executive under Section 5, a single lump sum
equal to (i) the Executive's Annual Compensation during the most recently
completed fiscal year multiplied by (ii) 2.67. As used herein, "Annual
Compensation" shall include Base Salary and any bonuses paid to the Executive
with respect to any such year. Such payment shall be made in a lump sum no later
than 30 days after the Date of Termination. Such payments shall not be reduced
in the event Executive obtains other employment following termination of
employment.

         (d) Upon the Executive's entitlement to benefits pursuant to Section
6(b), the Company will cause to be continued life, medical and dental coverage
substantially equivalent to the coverage maintained by the Company for Executive
prior to his severance at no premium cost to Executive. Such coverage and
payments shall cease upon the earliest of (i) the expiration of 60 months
following the Date of Termination, (ii) the date upon which the Executive
obtains other employment which provides similar coverage, or (iii) the date upon
which Executive qualifies for Medicare benefits under federal law.

         (e) Upon the Executive's entitlement to benefits pursuant to Section
6(b)(ii), the Change of Control vesting provisions of the Executive's restricted
stock award, which are described in Attachment B to this Agreement, shall apply.

                                       5
<PAGE>

         (f) If a Change in Control occurs after the end of the Employment Term
and prior to the date the Executive's restricted stock units granted under
Section 5(c) have vested, then (i) if the Executive's employment is terminated
after such Change of Control for: (I) death or disability, (II) by the Company
without Cause, or (III) by the Executive with Good Reason, then the Executive
shall be paid a single lump sum equal to (A) the Executive's Annual Compensation
during the most recently completed fiscal year multiplied by (B) 2.67; and (ii)
the Change of Control vesting provisions of the Executive's restricted stock
award, which are described in Attachment B to this Agreement, shall apply. The
payment under the preceding sentence shall be made in a single lump sum no later
than 30 days after the Date of Termination and shall not be reduced in the event
the Executive obtains other employment following termination of employment.

         (g) If a Change of Control occurs prior to the earlier of (i) October
6, 2005, or (ii) 15 months following the consummation of an initial public
offering of the Company's common stock, the No Competition provision of Section
12 and the No Tampering provision of Section 13 shall apply during the 12-month
period commencing on the earlier of (i) October 6, 2005, or (ii) 15 months
following the consummation of an initial public offering of the Company's common
stock. The Executive and the Company hereby agree that the benefits provided
pursuant to Sections 6(c), 6(d) and 6(e) above are compensation for the
extension of these No Competition and No Tampering provisions of this Agreement.

         (h) If a Change of Control occurs after the earlier of (i) October 6,
2005, or (ii) 15 months following the consummation of an initial public offering
of the Company's common stock, and prior to the date all of the Executive's
restricted stock units granted under Section 5(c) have vested, the No
Competition provision of Section 12 and the No Tampering provision of Section 13
shall apply during the 12-month period commencing on the earlier of (i) October
6, 2005, or (ii) 15 months following the consummation of an initial public
offering of the Company's common stock. The Executive and the Company hereby
agree that the benefits provided pursuant to Sections 6(f), above are
compensation for the extension of these No Competition and No Tampering
provisions of this Agreement..

         (i) Notwithstanding the other provisions of this Section 6, in the
event that:

                  (i) the aggregate payments or benefits to be made or afforded
         to the Executive, which are deemed to be parachute payments as defined
         in Section 280G of the Internal Revenue Code of 1986, as amended (the
         "Code") or any successor thereof, (the "Termination Benefits") would be
         deemed to include an "excess parachute payment" under Section 280G of
         the Code; and

                  (ii) if such Termination Benefits were reduced to an amount
         (the "Non-Triggering Amount"), the value of which is one dollar ($1.00)
         less than an amount equal to three (3) times Executive's "base amount,"
         as determined in accordance with Section 280G and the Non-Triggering
         Amount less the product of the marginal rate of any applicable state
         and federal income tax and the Non-

                                       6
<PAGE>

         Triggering Amount would be greater than the aggregate value of the
         Termination Benefits (without such reduction) minus (a) the amount of
         tax required to be paid by the Executive thereon by Section 4999 of the
         Code and further minus (b) the product of the Termination Benefits and
         the marginal rate of any applicable state and federal income tax, then
         the Termination Benefits shall be reduced to the Non-Triggering Amount.
         The allocation of the reduction required hereby among the Termination
         Benefits shall be determined by the Executive.

         7. CONFIDENTIAL INFORMATION. The Company agrees to provide Executive
with its Confidential Information (as defined below). The Executive recognizes
and acknowledges that he will have access to certain information of members of
the Company Group (as defined below) and that such information is confidential
and constitutes valuable, special and unique property of such members of the
Company Group. In exchange for the Company's agreement to provide him with its
Confidential Information (as defined below), the Executive agrees that he shall
not at any time, either during or subsequent to the Employment Term, disclose to
others, use, copy or permit to be copied, except in pursuance of his duties for
and on behalf of the Company, its successors, assigns or nominees, any
Confidential Information of any member of the Company Group (regardless of
whether developed by the Executive) without the prior written consent of the
Company or as required by law.

         As used herein, "Company Group" means the Company and any entity that
directly or indirectly controls, is controlled by, or is under the common
control with, the Company, and for the purposes of this definition "control"
means the possession, directly or indirectly, of the power to direct or cause
the direction of the management and policies of such entity, whether through the
ownership of voting securities, by contract or otherwise.

         The term "Confidential Information" with respect to the Company means
any secret or confidential information or know-how and shall include, but shall
not be limited to, marketing plans, lending practices, business plans, the
plans, customers, costs, prices, uses, and application of products and services,
results of investigations, studies or experiments owned or used by the Company,
and all apparatus, products, processes, compositions, samples, formulas,
computer programs, computer hardware designs, computer firmware designs, and
servicing, marketing or manufacturing methods and techniques at any time used,
developed, investigated, made or sold by the Company, before or during the
Employment Term, that are not readily available to the public or that are
maintained as confidential by the Company. The Executive shall maintain in
confidence any Confidential Information of third parties received as a result of
his employment with the Company in accordance with the Company's obligations to
such third parties and the policies established by the Company.

         8. DELIVERY OF DOCUMENTS UPON TERMINATION. The Executive shall
immediately deliver to the Company or its designee at the termination of his
employment all correspondence, memoranda, notes, records, drawings, sketches,
plans, customer lists, product compositions, and other documents and all copies
thereof, made, composed or received by the Executive, solely or jointly with
others, that are in the Executive's possession, custody, or control at
termination and that are related in any manner to the past, present, or
anticipated business of any member of the Company Group. In this regard, the
Executive hereby grants and conveys to the Company all

                                       7
<PAGE>

right, title and interest in and to, including without limitation, the right to
possess, print, copy, and sell or otherwise dispose of, any reports, records,
papers, summaries, photographs, drawings or other documents, and writings, and
copies, abstracts or summaries thereof, that may be prepared by the Executive or
under his direction or that may come into his possession in any way during the
term of his employment with the Company that relate in any manner to the past,
present or anticipated business of any member of the Company Group.

         9. DISCLOSURE AND RECEIPT OF CONFIDENTIAL INFORMATION. The Executive
shall not, at any time during his employment, knowingly receive from persons not
employed by the Company, any Confidential Information, as described above, not
belonging to the Company, unless a valid agreement is authorized by the Company
and is signed by both the Company and by the disclosing party. The Executive
shall not use or disclose to other employees of the Company, during his
employment with Company, Confidential Information belonging to his former
employers, former business associates, or any other third parties unless written
permission has been given by such third parties to the Company and accepted by
the Company to allow the Company to use and/or disclose such information. The
Executive shall defend and indemnify the Company Group for any breach of the
covenant contained in the preceding sentence.

         10. INTELLECTUAL PROPERTY. The Executive shall hold in trust for the
benefit of the Company, and shall disclose promptly and fully to the Company in
writing, and hereby assigns, and binds his heirs, executors, and administrators
to assign, to the Company any and all inventions, discoveries, ideas, concepts,
improvements, copyrightable works, and other developments (the "Developments")
conceived, made, discovered or developed by him, solely or jointly with others,
during the term of his employment by the Company, whether during or outside of
usual working hours and whether on the Company's premises or not, that relate in
any manner to the past, present or anticipated business of any member of the
Company Group. All works of authorship created by the Executive during the
Employment Term and any extension hereof, solely or jointly with others, shall
be considered works made for hire under the Copyright Act of 1976, as amended,
and shall be owned entirely by the Company. Any and all such Developments shall
be the sole and exclusive property of the Company, whether patentable,
copyrightable, or neither, and the Executive shall assist and fully cooperate in
every way, at the Company's expense, in securing, maintaining, and enforcing,
for the benefit of the Company or its designee, patents, copyrights or other
types of proprietary or intellectual property protection for such Developments
in any and all countries.

         11. FURTHER ACTS. At the request of the Company (but without additional
compensation from the Company during his employment by the Company) the
Executive shall execute any and all papers and perform all lawful acts that the
Company may deem necessary or appropriate to further evidence or carry out the
transactions contemplated by this Agreement including, without limitation, such
acts as may be necessary for the preparation, filing, prosecution, and
maintenance of applications for United States letters patent and foreign letters
patent, or for United States and foreign copyright, on the Developments.

         12. NO COMPETITION. Until October 6, 2005, and while employed by the
Company, the Executive shall not directly or indirectly engage in the business
of operating a state or national bank or company providing similar services, or
any other business in which any member

                                       8
<PAGE>

of the Company Group directly or indirectly engages during the Employment Term;
provided, however, that the restriction in this Section 12 shall apply only to
the reasonable and limited geographic area consisting of any state where any
member of the Company Group has an office, bank location or place of business,
and Texas and any state that has a contiguous border with the State of Texas.
For purposes of this Section 12, the Executive shall be deemed to engage in such
a business if he directly or indirectly, engages or invests in, owns, manages,
operates, controls or participates in the ownership, management, operation or
control of, is employed by, associated or in any manner connected with, or
renders services or advice to, any business engaged in operating a state or
national bank or other company providing similar services to those provided by
the any member of the Company Group during the Employment Term; provided,
however, that the Executive may invest in the securities of any enterprise (but
without otherwise participating in the activities of such enterprise) if (x)
such securities are listed on any national or regional securities exchange or
have been registered under Section 12 of the Securities Exchange Act of 1934 and
(y) the Executive does not beneficially own (as defined Rule 13d-3 promulgated
under the Securities Exchange Act of 1934) in excess of 5% of the outstanding
capital of such enterprise.

         The Executive agrees that if a court of competent jurisdiction
determines that the length of time or any other restriction, or portion thereof,
set forth in this Section 12 is overly restrictive and unenforceable, the court
may reduce or modify such restrictions to those which it deems reasonable and
enforceable under the circumstances, and as so reduced or modified, the parties
hereto agree that the restrictions of this Section 12 shall remain in full force
and effect. The Executive further agrees that if a court of competent
jurisdiction determines that any provision of this Section 12 is invalid or
against public policy, the remaining provisions of this Section 12 and the
remainder of this Agreement shall not be affected thereby, and shall remain in
full force and effect.

         The Executive acknowledges that the business of the Company and its
Affiliates is national in scope and that the restrictions imposed by this
Agreement are legitimate, reasonable and necessary to protect the Company's and
its affiliates' investment in their businesses and the goodwill thereof. The
Executive acknowledges that the scope and duration of the restrictions contained
herein are reasonable in light of the time that the Executive has been engaged
in the business of the Company and its affiliates, the Executive's reputation in
the markets for the Company's and its affiliates' businesses and the Executive's
relationship with the suppliers, customers and clients of the Company and its
affiliates. The Executive further acknowledges that the restrictions contained
herein are not burdensome to the Executive in light of the consideration paid
therefor.

         13. NO TAMPERING. Until October 6, 2005 and while employed by the
Company (and for any period following the Employment Term during which Executive
is receiving base salary pursuant to Section 5(b)(i) hereof), the Executive
shall not (a) request, induce or attempt to influence any distributor or
supplier of goods or services to any member of the Company Group to curtail or
cancel any business they may transact with any member of the Company Group; (b)
request, induce or attempt to influence any customer of any member of the
Company Group that have done business with or potential customers which have
been in contact with any member of the Company Group to curtail or cancel any
business they may transact with any member of the

                                       9
<PAGE>

Company Group; (c) request, induce or attempt to influence any employee of any
member of the Company Group to terminate his or her employment with such member
of the Company Group; or (d) hire or employ or attempt to hire or employ any
employee of any member of the Company Group.

         Should Executive voluntarily terminate his employment with the Company
for other than Good Cause prior to October 6, 2005, the Company may at its
option, elect to extend the duration of the prohibitions against Executive
contained in (c) and (d) of this Section 13 for a period of an additional 12
months following the date of such termination. To exercise such option the
Company must provide written notice of such election to Executive within 30 days
after such termination and pay to Executive an amount equal to the base pay and
bonus, if any, earned by Executive during his last 12 months of employment with
the Company (less any required withholding or other taxes). In such event such
amount shall be paid in equal monthly installments over such 12 month period.

         14. NON-DISPARAGEMENT. The Executive and the Company agree that neither
party shall at any time disparage, make negative comments or express negative
opinions regarding the other party, either publicly or privately, in any
communications with third-parties, verbal, written or otherwise.

         15. PUBLICITY AND ADVERTISING. The Executive agrees that the Company
may use his name, picture, or likeness for any advertising, publicity or other
business purpose at any time, during the term of this Agreement and may continue
to use materials generated during the term of this Agreement for a period of six
months thereafter. Such use of the Executive's name, picture, or likeness shall
not be deemed to result in any invasion of the Executive's privacy or in
violation of any property right the Executive may have; and the Executive shall
receive no additional consideration if his name, picture or likeness is so used.
The Executive further agrees that any negatives, prints or other material for
printing or reproduction purposes prepared in connection with the use of his
name, picture or likeness by the Company shall be and are the sole property of
the Company.

         16. REMEDIES. The Executive acknowledges that a remedy at law for any
breach or attempted breach of the Executive's obligations under Sections 7
through 15 may be inadequate, agrees that the Company is entitled to specific
performance and injunctive and other equitable remedies in case of any such
breach or attempted breach. The Company shall have the right to offset against
amounts to be paid to the Executive pursuant to the terms hereof any amounts
from time to time owing by the Executive to the Company. The termination of
Executive's employment shall not be deemed to be a waiver by the Company of any
breach by the Executive of this Agreement or any other obligation owed the
Company, and notwithstanding such a termination the Executive shall be liable
for all damages attributable to such breach. The Executive acknowledges that the
scope and duration of the restrictions contained herein are reasonable in light
of the time that the Executive has been engaged in the business of the Company
and its affiliates, the Executive's reputation in the markets for the Company's
and its affiliates' businesses and the Executive's relationship with the
suppliers, customers and clients of the Company and its affiliates. The
Executive further acknowledges that the restrictions contained herein are not
burdensome to the Executive in light of the consideration paid therefor.

         17. INDEMNIFICATION.

                  (a) In the event that the Executive is made a party or is
         threatened to be made a party to any threatened, pending or completed
         action, suit or proceeding, whether civil, criminal, administrative or
         investigative, other than an action by or in the right of the Company,
         by reason of the fact that the Executive is or was a director, officer,
         employee, trustee or agent of the Company, or is or was serving at the
         request of the Company as a director, officer, employee trustee or
         agent of another corporation, partnership, joint venture, trust or
         other enterprise (including employee benefit plans), expressly
         including service as a director, officer or in a similar position with
         any exchange, board of trade, clearing corporation or similar
         institution on which the Company or any other corporation a majority of
         the stock of which is owned directly or indirectly by the Company had
         membership privileges at the relevant time during which any such
         position was held, shall be indemnified by the Company against
         expenses, including attorneys' fees, judgments, fines and amounts paid
         in settlement actually and reasonably incurred by the Executive in
         connection with such action, suit or proceeding if he acted in good
         faith and in a manner he reasonably believed to be in or not opposed to
         the best interests of the Company, and, with respect to any criminal
         action or proceeding, had no reasonable cause to believe his conduct
         was unlawful; provided, that funds paid or required to be paid to the
         Executive as a result of the provisions of this Section 17 shall be
         returned to the Company or reduced, as the case may be, to the extent
         that the Executive receives funds pursuant to an indemnification from
         any other corporation or organization. With respect to any employee
         benefit plan which imposes duties on, or involves services by, the
         Executive, if the Executive acted in good faith and in a manner he
         reasonably believed to be in the interest of the participants and
         beneficiaries of an employee benefit plan, he shall be deemed to have
         acted in a manner not opposed to the best interests of the corporation.
         If the Executive could be indemnified pursuant to the first sentence of
         this Section 17(a) except for the fact that the subject action or suit
         is or was by or in the right of the Company, he shall be indemnified by
         the Company against expenses including attorneys' fees actually and
         reasonably incurred by him in connection with the defense or settlement
         of such action or suit, except that no indemnification shall be made in
         respect of such action or suit, in respect of any claim, issue or
         matter as to which the Executive shall have been adjudged to be liable
         for negligence or misconduct in the performance of his duty to the
         Company unless and only to the extent that the court in which such
         action or suit was brought shall determine upon application that,
         despite the adjudication of liability but in view of all the
         circumstances of the case, the Executive is fairly and reasonably
         entitled to indemnity for such expenses which such court shall deem
         proper.

                  (b) To the extent that the Executive has been successful on
         the merits or otherwise in defense of any action, suit or proceeding
         referred to in Section 17(a), or in defense of any claim, issue or
         matter therein, he shall be indemnified by the Company against
         expenses, including attorneys' fees, actually and reasonably incurred
         by him in connection therewith without the necessity of any action
         being taken by the Company. In all cases wherein such indemnification
         is provided by this Section 17, unless ordered by a court,
         indemnification shall be made by the Company only as authorized in the
         specific case upon a determination that indemnification of the
         Executive is proper in the

                                       11
<PAGE>

         circumstances because he has met the applicable standard of conduct
         specified in this Section 17. Such determination shall be made (i) by a
         majority vote of the directors who are not parties to such action, suit
         or proceeding, even though less than a quorum or (ii) by a committee of
         such directors designated by majority vote of such directors, even
         though less than a quorum or (iii) if there are no such directors, or
         if such directors so direct, by independent legal counsel in a written
         opinion or (iv) by the Board of Directors by a majority vote of a
         quorum consisting of directors who were not parties to such action,
         suit or proceeding or (v) if such quorum is not obtainable, or, even if
         obtainable a quorum of disinterested directors so directs, by
         independent legal counsel in a written opinion, or (vi) by the holders
         of a majority of the shares of capital stock of the Company entitled to
         vote thereon.

                  (c) The termination of any action, suit or proceeding by
         judgment, order, settlement, conviction or upon a plea of nolo
         contendere or its equivalent, shall not, of itself, create a
         presumption that the Executive did not act in good faith and in a
         manner which he reasonably believed to be in or not opposed to the best
         interests of the Company, and, with respect to any criminal action or
         proceeding, had reasonable cause to believe that his conduct was
         unlawful. Entry of a judgment by consent as part of a settlement shall
         not be deemed a final adjudication of liability for negligence or
         misconduct in the performance of duty, nor of any other issue or
         matter.

                  (d) Expenses incurred in defending a civil, criminal,
         administrative or investigative action, suit or proceeding may be paid
         by the Company in advance of the final disposition of such action, suit
         or proceeding as authorized by the Board of Directors in the specific
         case upon receipt of an undertaking by the Executive to repay such
         amount if it shall ultimately be determined that he is not entitled to
         be indemnified by the Company.

                  (e) The indemnification hereby provided shall not be deemed
         exclusive of any other rights to which the Executive may be entitled
         under any bylaw, agreement, vote of stockholders or disinterested
         directors or otherwise, both as to action in an official capacity and
         as to action in another capacity while holding such office, and shall
         continue as to the Executive once he has ceased to provide services to
         the Company.

         18. MISCELLANEOUS PROVISIONS.

                  (a) Executive's Heirs, etc. The Executive may not assign his

         the Company. No waiver by either party hereto at any time of any breach
         by the other party hereto of, or compliance with any condition or

                 TERMS AND CONDITIONS OF RESTRICTIVE STOCK UNITS

EQUITY COMPENSATION

         The equity compensation paid to the Executive under Section 4(c) of the
Agreement will be in the form of Restricted Stock Units ("RSUs"). RSUs are award
units under the 1999 Omnibus Stock Plan of the Company that represent agreements
by the Company to deliver a share of the Company's common stock to the Executive
if the delivery conditions of the RSUs are met.

         53,750 RSUs will be awarded to the Executive pursuant to a Restricted
Stock Unit Grant Agreement (the "RSU Agreement") between the Executive and the
Company.

CONDITIONS TO DELIVERY OF STOCK;  DEFERRAL;  VESTING

         For the shares of the Company's common stock underlying the RSUs to be
delivered: (1) the Deferral Date must have been reached and (2) the RSUs must be
vested.

         Deferral. To allow taxation with respect to the RSUs to be delayed,
delivery of the Company's common stock underlying the RSUs will take place upon
a date or dates selected by Executive (the "Deferral Date") prior to entering
into the RSU Agreement. Such date or dates must be after vesting, but in no
event may the last date be after __________.

         Vesting. 3,750 RSUs will become vested if Executive remains employed by
the Company on the first anniversary of his date of hire. All remaining unvested
RSUs will vest on October 6, 2009 if Executive remains employed by the Company
on that date. Vesting may be accelerated if the closing price of the Company's
common stock exceeds a target price for at least 45 of 60 consecutive trading
days. The following schedule (the "Accelerated Vesting Schedule") sets forth the
target prices and corresponding incremental and cumulative accelerated vested
amounts:

any calendar year.

EFFECT OF CHANGE OF CONTROL

         The following occurs upon a Change of Control:

         (1)      the Deferral Date remains unchanged;

         (2)      all vested RSUs at the time of the Change of Control remain
                  vested;

         (3)      all unvested RSUs at the time of the Change of Control vest
                  according to the Change of Control Vesting Schedule; and

         (4)      the board of directors of the Company may elect to provide an
                  alternative form of compensation to be delivered with respect
                  to vested RSUs on the Deferral Date, in their sole discretion,
                  if warranted by the transaction that causes the Change of
                  Control ("Alternative RSU Compensation").

         Change of Control Vesting Schedule. Upon a Change of Control, all
unvested RSUs at the time of the Change of Control vest according to the
following:

         (1)      50% vest immediately upon the Change of Control;

         (2)      if the Executive continues to be employed by the Company two
                  years after the Change of Control, all remaining RSUs vest two
                  years after the Change of Control or on October 6, 2009, if
                  earlier;

         (3)      if the Executive's employment is terminated after the Change
                  of Control for death/disability, by the Company without Cause
                  or by the Executive with Good Reason, all remaining RSUs vest
                  upon the Termination Date; or

         (4)      if the Executive's employment was terminated after the Change
                  of Control by the Company with Cause or by the Executive
                  without Good Reason, all remaining unvested RSUs are
                  forfeited.

ALTERNATIVE RSU COMPENSATION

         As a result of the circumstances surrounding a Change of Control or
anticipated Change of Control, the Company's board of directors, in its sole and
absolute discretion, may elect prior to a Change of Control to allow
compensation in a form other than the Company's common stock to be delivered
with respect to vested RSUs upon the Deferral Date. Such alternative
compensation could include: (1) a dollar denominated deferred compensation
arrangement bearing a defined market interest rate; or (2) if the Change of
Control were to take the form of an acquisition of the Company, RSUs with
respect to a number of shares of stock of the acquiring company with an
aggregate market value equivalent to the RSUs with respect to the Company's
common stock. In addition, the Company's board of directors may elect to place
the assets underlying the RSUs, whether in the form of the Company's common
stock or an alternate form of asset, into a "Rabbi Trust", which would provide
additional surety that the obligations represented by the RSUs would be
fulfilled.

                          DISPUTE RESOLUTION PROCEDURES

The parties agree to make a good faith effort to informally resolve any dispute
before submitting the dispute to arbitration in accordance with the following
procedures:

A.       The party claiming to be aggrieved shall furnish to the other a written
         statement of the grievance, all persons whose testimony would support
         the grievance, and the relief requested or proposed. The written
         statements must be delivered to the other party within the time limits
         for bringing an administrative or court action based on that claim.

B.       If the other party does not agree to furnish the relief requested or
         proposed, or otherwise does not satisfy the demand of the party
         claiming to be aggrieved within 30 days and the aggrieved party wishes
         to pursue the issue, the aggrieved party shall by written notice demand
         that the dispute be submitted to non-binding mediation before a
         mediator jointly selected by the parties.

C.       If mediation does not produce a resolution of the dispute and either
         party wishes to pursue the issue, that party shall be entitled to
         request binding arbitration of the dispute by giving written notice to
         the other party within 30 days after mediation. The parties will
         attempt to agree on a mutually acceptable arbitrator and, if no
         agreement is reached, the parties will request a list of nine
         arbitrators from the American Arbitration Association and select by
         alternately striking names. The arbitration will be conducted
         consistent with the American Arbitration Association's National Rules
         for Resolution of Employment Disputes ("Rules") that are in effect at
         the time of the arbitration. If there is any conflict between those
         Rules and the terms of this Agreement, including all attachments
         thereto, this Agreement will govern. The arbitrator shall have
         authority to decide whether the conduct complained of under Subsection
         (a) above violates the legal rights of the parties. In any such
         arbitration proceeding, any hearing must be transcribed by a certified
         court reporter and any decision must be supported by written findings
         of fact and conclusions of law. The arbitrator's findings of fact must
         be supported by substantial evidence on the record as a whole and the
         conclusions of law and any remedy must be provided for by and
         consistent with the laws of Texas and federal law. The arbitrator shall
         have no authority to add to, modify, change or disregard any lawful
         term of this Agreement. The Company will pay the arbitrator's fee.

D.       Arbitration shall be the exclusive means for final resolution of any
         dispute between the parties, except 1) for workers' compensation and
         unemployment claims and 2) when injunctive relief is necessary to
         preserve the status quo or to prevent irreparable injury, including but
         not limited to an alleged or threatened breach of Sections 7-14 of this
         Agreement. Injunctive relief may be sought from any court of competent
         jurisdiction located in Texas.
