                      THE COMMITMENTS AND CREDIT EXTENSIONS

      SECTION 2.01 REVOLVING LOANS. Subject to the terms and conditions set
forth herein, each Lender with a Revolving Commitment severally agrees to make
loans (each such loan, a "Revolving Loan") to the Borrower from time to time, on
any Business Day during the Revolving Availability Period, in an aggregate
amount not to exceed at any time outstanding the amount of such Lender's
Revolving Commitment; provided, however, that after giving effect to any
Revolving Borrowing, (i) the Total Revolving Outstandings and the Outstanding
Amount of all Swing Line Loans shall not exceed the Aggregate Revolving
Commitments, and (ii) the aggregate Outstanding Amount of the Revolving Loans of
any Lender, plus such Lender's Revolving Pro Rata Share of the Outstanding
Amount of all L/C Obligations, plus such Lender's Revolving Pro Rata Share of
the Outstanding Amount of all Swing Line Loans shall not exceed such Lender's
Revolving Commitment. Within the limits of each Lender's Revolving Commitment,
and subject to the other terms and conditions hereof, the Borrower may borrow
under this Section 2.01, prepay under Section 2.06, and reborrow under this
Section 2.01. Revolving Loans may be Base Rate Loans and/or LIBOR Loans, as
further provided herein.

      SECTION 2.02 TERM LOANS. Subject to the terms and conditions set forth
herein, each Lender with a Term Commitment severally agrees to make a Term Loan
on the Closing Date in the amount of its Term Commitment. Term Loans may not be
repaid and then reborrowed.

      SECTION 2.03 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

            (a) Each Borrowing, each conversion of Loans from one Type to the
      other, and each continuation of LIBOR Loans shall be made upon the
      Borrower's irrevocable notice to the Administrative Agent, which may be
      given by telephone. Each such notice

                                       27
<PAGE>

      must be received by the Administrative Agent not later than 11:00 a.m. (i)
      three Business Days prior to the requested date of any Borrowing of or
      conversion to or continuation of LIBOR Loans, and (ii) on the requested
      date of any Borrowing of Base Rate Loans. Each telephonic notice by the
      Borrower pursuant to this Section 2.03(a) must be confirmed promptly by
      delivery to the Administrative Agent of a written Revolving Loan Notice or
      Term Loan Notice, as applicable, appropriately completed and signed by a
      Responsible Officer of the Borrower. Each Borrowing of, conversion to or
      continuation of LIBOR Loans shall be in a principal amount of $1,000,000
      or a whole multiple of $500,000 in excess thereof. Except as provided in
      Sections 2.04(c) and 2.05(c), each Borrowing (other than a Swing Line
      Loan) 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
      Revolving Loan Notice or Term Loan Notice, as applicable (whether
      telephonic or written), shall specify (i) whether the Borrower is
      requesting a Borrowing, a conversion of Loans from one Type to the other,
      or a continuation of LIBOR Loans, (ii) the requested date of the
      Borrowing, conversion or continuation, as the case may be (which shall be
      a Business Day), (iii) the principal amount of Loans to be borrowed,
      converted or continued, (iv) the Type of Loans to be borrowed or to which
      existing Loans are to be converted, and (v) if applicable, the duration of
      the Interest Period with respect thereto. If the Borrower fails to specify
      a Type of Loan in a Revolving Loan Notice or Term Loan Notice, as
      applicable, or if the Borrower fails to give a timely notice requesting a
      conversion or continuation, then the applicable Loans shall be made as, or
      converted to, Base Rate Loans. Any such automatic conversion to Base Rate
      Loans shall be effective as of the last day of the Interest Period then in
      effect with respect to the applicable LIBOR Loans. If the Borrower
      requests a Borrowing of, conversion to, or continuation of LIBOR Loans in
      any such Revolving Loan Notice or Term Loan Notice, as applicable, 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 Revolving Loan Notice or Term Loan
      Notice, as applicable, the Administrative Agent shall promptly notify each
      Lender of the amount of its Revolving Pro Rata Share or Term Pro Rata
      Share of the applicable Loans, and if no timely notice of a conversion or
      continuation is provided by the Borrower, the Administrative Agent shall
      notify each Lender of the details of any automatic conversion to Base Rate
      Loans described in the preceding subsection. In the case of a Revolving
      Borrowing or the Term Borrowing, each Lender shall make the amount of its
      Loan available to the Administrative Agent in immediately available funds
      at the Administrative Agent's Office not later than 1:00 p.m. on the
      Business Day specified in the applicable Loan Notice. Upon satisfaction of
      the applicable conditions set forth in Section 4.02 (and, if such
      Borrowing is the initial Credit Extension, Section 4.01), the
      Administrative Agent shall make all funds so received available to the
      Borrower in like funds as received by the Administrative Agent either by
      (i) crediting the account of the Borrower on the books of Wells Fargo with
      the amount of such funds or (ii) wire transfer of such funds, in each case
      in accordance with instructions provided to (and reasonably acceptable to)
      the Administrative Agent by the Borrower; provided, however, that if, on
      the date the Revolving Loan Notice with respect to such Borrowing is given
      by the Borrower, there are Swing Line Loans or L/C Borrowings outstanding,
      then the proceeds of such Borrowing shall be applied, first, to the
      payment in full of any such L/C

                                       28
<PAGE>

      Borrowings, second, to the payment in full of any such Swing Line Loans,
      and third, to the Borrower as provided above.

            (c) Except as otherwise provided herein, a LIBOR Loan may be
      continued or converted only on the last day of an Interest Period for such
      LIBOR Loan. During the existence of a Default, no Loans may be requested
      as, converted to or continued as LIBOR Loans without the consent of the
      Required Lenders.

            (d) The Administrative Agent shall promptly notify the Borrower and
      the Lenders of the interest rate applicable to any Interest Period for
      LIBOR Loans upon determination of such interest rate. The determination of
      LIBOR by the Administrative Agent shall be conclusive in the absence of
      manifest error. At any time that Base Rate Loans are outstanding, the
      Administrative Agent shall notify the Borrower and the Lenders of any
      change in the 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 six Interest Periods in effect with
      respect to Revolving Loans and six with respect to Term Loans.

            Business Day during the period from the Closing Date until the

            account of the Borrower or its Subsidiaries, and to amend or extend
            Letters of Credit previously issued by it, in accordance with
            subsection (b) below, and (2) to honor drafts under the Letter of
            Credit; and (B) the Lenders with Revolving Commitments severally
            agree to participate in Letters of Credit issued for the account of
            the Borrower; provided that the L/C Issuer shall not be obligated to
            make any L/C Credit Extension with respect to any Letter of Credit,
            and no Lender shall be obligated to participate in any Letter of
            Credit if as of the date of such L/C Credit Extension, (x) the Total
            Revolving Outstandings would exceed the Aggregate Revolving
            Commitments, (y) the aggregate Outstanding Amount of the Revolving
            Loans of any Lender, plus such Lender's Revolving Pro Rata Share of
            the Outstanding Amount of all L/C Obligations, plus such Lender's
            Revolving Pro Rata Share of the Outstanding Amount of all Swing Line
            Loans would exceed such Lender's Revolving Commitment, or (z) the
            Outstanding Amount of the L/C Obligations would exceed the Letter of
            Credit Sublimit. Each request by the Borrower for the issuance or
            amendment of a Letter of Credit shall be deemed to be a
            representation by the Borrower that the L/C Credit Extension so
            requested complies with the conditions set forth in the proviso to
            the preceding sentence. Within the foregoing limits, and subject to
            the terms and conditions

                                       29
<PAGE>

            hereof, the Borrower's ability to obtain Letters of Credit shall be
            fully revolving, and accordingly the Borrower may, during the
            foregoing period, obtain Letters of Credit to replace Letters of
            Credit that have expired or that have been drawn upon and
            reimbursed.

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

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

                        (B) the issuance of such Letter of Credit would violate
                  any Laws or one or more policies of the L/C Issuer;

                        (C) such Letter of Credit contains any provision for
                  automatic reinstatement of any stated amount after any drawing
                  thereunder; or

                        (D) a default of any Lender's obligation to fund under
                  Section 2.04(c) exists or any Lender is at such time a
                  Defaulting Lender hereunder, unless the L/C Issuer has entered
                  into a satisfactory arrangement with the Borrower or such
                  Lender to eliminate the L/C Issuer's risk with respect to such
                  Lender.

                  (iii) The L/C Issuer shall not issue any Letter of Credit if:

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

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

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

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

                  (vi) The L/C Issuer shall act on behalf of the Lenders with
            respect to any Letters of Credit issued by it and the documents
            associated therewith, and the L/C Issuer shall have all of the
            benefits and immunities (A) provided to the Administrative Agent in
            Article IX with respect to any acts taken or omissions suffered by
            the L/C Issuer in connection with Letters of Credit issued by it or
            proposed to be issued by it and Issuer Documents pertaining to such
            Letters of Credit as fully as if the term "Administrative Agent" as
            used in Article IX included the L/C Issuer with respect to such acts
            or omissions, and (B) as additionally provided herein with respect
            to the L/C Issuer.

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

                  (ii) Promptly after receipt of any Letter of Credit
            Application, the L/C Issuer will confirm with the Administrative
            Agent (by telephone or in writing) that the Administrative Agent has
            received a copy of such Letter of Credit Application from the
            Borrower and, if not, the L/C Issuer will provide the Administrative
            Agent with a copy thereof. Unless the L/C Issuer has received
            written notice from any Lender, the Administrative Agent or any Loan
            Party, at least one Business Day prior to the requested date of
            issuance or amendment of

                                       31
<PAGE>

            the applicable Letter of Credit, that one or more applicable
            conditions contained in Article IV shall not then be satisfied,
            then, subject to the terms and conditions hereof, the L/C Issuer
            shall, on the requested date, issue a Letter of Credit for the
            account of the Borrower or the applicable Subsidiary or enter into
            the applicable amendment, as the case may be, in each case in
            accordance with the L/C Issuer's usual and customary business
            practices. Immediately upon the issuance of each Letter of Credit,
            each Lender with a Revolving Commitment shall be deemed to, and
            hereby irrevocably and unconditionally agrees to, purchase from the
            L/C Issuer a risk participation in such Letter of Credit in an
            amount equal to the product of such Lender's Revolving Pro Rata
            Share times the amount of such Letter of Credit.

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

            (c) Drawings and Reimbursements; Funding of Participations.

                  (i) Upon receipt from the beneficiary of any Letter of Credit
            of any notice of a drawing under such Letter of Credit, the L/C
            Issuer shall notify the Borrower and the Administrative Agent
            thereof. Not later than 11:00 a.m. on the date of any payment by the
            L/C Issuer under a Letter of Credit (each such date, an "Honor
            Date"), the Borrower shall reimburse the L/C Issuer through the
            Administrative Agent in an amount equal to the amount of such
            drawing. If the Borrower fails to so reimburse the L/C Issuer by
            such time, the Administrative Agent shall promptly notify each
            Lender of the Honor Date, the amount of the unreimbursed drawing
            (the "Unreimbursed Amount"), and the amount of such Lender's
            Revolving Pro Rata 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 2.03 for the principal amount of Base Rate Loans, but
            subject to the amount of the unutilized portion of the Aggregate
            Revolving Commitments and the conditions set forth in Section 4.02
            (other than the delivery of a Revolving Loan Notice). Any notice
            given by the L/C Issuer or the Administrative Agent pursuant to this
            Section 2.04(c)(i) may be given by telephone if immediately
            confirmed in writing; provided that the lack of such an immediate
            confirmation shall not affect the conclusiveness or binding effect
            of such notice.

                  (ii) Each Lender with a Revolving Commitment (including the
            Lender acting as L/C Issuer) shall upon any notice pursuant to
            Section 2.04(c)(i) make funds available to the Administrative Agent
            for the account of the L/C Issuer at the Administrative Agent's
            Office in an amount equal to its Revolving Pro Rata Share of the
            Unreimbursed Amount not later than 1:00 p.m. on the Business Day
            specified in such notice by the Administrative Agent, whereupon,
            subject to the

                                       32
<PAGE>

            provisions of Section 2.04(c)(iii), each such 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 L/C Issuer.

                  (iii) With respect to any Unreimbursed Amount that is not
            fully refinanced by a Revolving Borrowing of Base Rate Loans because
            the conditions set forth in Section 4.02 cannot be satisfied or for
            any other reason, the Borrower shall be deemed to have incurred from
            the L/C Issuer an L/C Borrowing in the amount of the Unreimbursed
            Amount that is not so refinanced, which L/C Borrowing shall be due
            and payable on demand (together with interest) and shall bear
            interest at the Default Rate. In such event, each such Lender's
            payment to the Administrative Agent for the account of the L/C
            Issuer pursuant to Section 2.04(c)(ii) shall be deemed payment in
            respect of its participation in such L/C Borrowing and shall
            constitute an L/C Advance from such Lender in satisfaction of its
            participation obligation under this Section 2.04.

                  (iv) Until each such Lender funds its Revolving Loan or L/C
            Advance pursuant to this Section 2.04(c) to reimburse the L/C Issuer
            for any amount drawn under any Letter of Credit, interest in respect
            of such Lender's Revolving Pro Rata Share of such amount shall be
            solely for the account of the L/C Issuer.

                  (v) Each such Lender's obligation to make Revolving Loans or
            L/C Advances to reimburse the L/C Issuer for amounts drawn under
            Letters of Credit, as contemplated by this Section 2.04(c), shall be
            absolute and unconditional and shall not be affected by any
            circumstance, including (A) any set-off, counterclaim, recoupment,
            defense or other right which such Lender may have against the L/C
            Issuer, the Borrower or any other Person for any reason whatsoever;
            (B) the occurrence or continuance of a Default (notwithstanding
            anything in Section 4.02 to the contrary), or (C) any other
            occurrence, event or condition, whether or not similar to any of the
            foregoing; provided, however, that each Lender's obligation to make
            Revolving Loans pursuant to this Section 2.04(c) is subject to the
            conditions set forth in Section 4.02 (other than delivery by the
            Borrower of a Revolving Loan Notice). No such making of an L/C
            Advance shall relieve or otherwise impair the obligation of the
            Borrower to reimburse the L/C Issuer for the amount of any payment
            made by the L/C Issuer under any Letter of Credit, together with
            interest as provided herein.

                  (vi) If any Lender fails to make available to the
            Administrative Agent for the account of the L/C Issuer any amount
            required to be paid by such Lender pursuant to the foregoing
            provisions of this Section 2.04(c) by the time specified in Section
            2.04(c)(ii), the L/C Issuer shall be entitled to recover from such
            Lender (acting through the Administrative Agent), on demand, such
            amount with interest thereon for the period from the date such
            payment is required to the date on which such payment is immediately
            available to the L/C Issuer at a rate per annum equal to the greater
            of the Federal Funds Rate and a rate determined by the L/C Issuer in
            accordance with banking industry rules on interbank compensation. A
            certificate of the L/C Issuer submitted to any Lender (through the
            Administrative Agent)

                                       33
<PAGE>

            with respect to any amounts owing under this clause (vi) shall be
            conclusive absent manifest error.

            (d) Repayment of Participations.

                  (i) At any time after the L/C Issuer has made a payment under
            any Letter of Credit and has received from any Lender such Lender's
            L/C Advance in respect of such payment in accordance with Section
            2.04(c), if the Administrative Agent receives for the account of the
            L/C Issuer any payment in respect of the related Unreimbursed Amount
            or interest thereon (whether directly from the Borrower or
            otherwise, including proceeds of Cash Collateral applied thereto by
            the Administrative Agent), the Administrative Agent will distribute
            to such Lender its Revolving Pro Rata Share thereof (appropriately
            adjusted, in the case of interest payments, to reflect the period of
            time during which such Lender's L/C Advance was outstanding) in the
            same funds as those received by the Administrative Agent.

                  (ii) If any payment received by the Administrative Agent for
            the account of the L/C Issuer pursuant to Section 2.04(c)(i) is
            required to be returned under any of the circumstances described in
            Section 10.05 (including pursuant to any settlement entered into by
            the L/C Issuer in its discretion), each such Lender shall pay to the
            Administrative Agent for the account of the L/C Issuer its Revolving
            Pro Rata Share thereof on demand of the Administrative Agent, plus
            interest thereon from the date of such demand to the date such
            amount is returned by such Lender, at a rate per annum equal to the
            Federal Funds Rate from time to time in effect. The obligations of
            the Lenders under this clause shall survive the payment in full of
            the Obligations and the termination of this Agreement.

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

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

                  (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 L/C Issuer or any other Person, whether in
            connection with this Agreement, the transactions contemplated hereby
            or by such Letter of Credit or any agreement or instrument relating
            thereto, or any unrelated transaction;

                  (iii) any draft, demand, certificate or other document
            presented under such Letter of Credit proving to be forged,
            fraudulent, invalid or insufficient in any respect or any statement
            therein being untrue or inaccurate in any respect; or

                                       34
<PAGE>

            any loss or delay in the transmission or otherwise of any document
            required in order to make a drawing under such Letter of Credit;

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

                  (v) any other circumstance or happening whatsoever, whether or
            not similar to any of the foregoing, including any other
            circumstance that might otherwise constitute a defense available to,
            or a discharge of, the Borrower or any other Loan Party.

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

            (f) Role of L/C Issuer. Each Lender with a Revolving Commitment and
      the Borrower agree that, in paying any drawing under a Letter of Credit,
      the L/C Issuer shall not have any responsibility to obtain any document
      (other than any sight draft, certificates and documents expressly required
      by the Letter of Credit) or to ascertain or inquire as to the validity or
      accuracy of any such document or the authority of the Person executing or
      delivering any such document. None of the L/C Issuer, the Administrative
      Agent, any of their respective Related Parties nor any of the respective
      correspondents, participants or assignees of the L/C Issuer shall be
      liable to any such Lender for (i) any action taken or omitted in
      connection herewith at the request or with the approval of the Lenders or
      the Required Lenders, as applicable; (ii) any action taken or omitted in
      the absence of gross negligence or willful misconduct; or (iii) the due
      execution, effectiveness, validity or enforceability of any document or
      instrument related to any Letter of Credit or Letter of Credit
      Application. The Borrower hereby assumes all risks of the acts or
      omissions of any beneficiary or transferee with respect to its use of any
      Letter of Credit; provided, however, that this assumption is not intended
      to, and shall not, preclude the Borrower's pursuing such rights and
      remedies as it may have against the beneficiary or transferee at law or
      under any other agreement. None of the L/C Issuer, the Administrative
      Agent, any of their respective Related Parties nor any of the respective
      correspondents, participants or assignees of the L/C Issuer, shall be
      liable or responsible for any of the matters described in clauses (i)
      through (v) of Section 2.04(e); provided, however, that anything in such
      clauses to the contrary notwithstanding, the Borrower may have a claim
      against the L/C Issuer, and the L/C Issuer may be liable to the Borrower,
      to the extent, but only to the extent, of any direct, as opposed to
      consequential or exemplary, damages suffered by the Borrower which the
      Borrower proves were caused by the L/C Issuer's willful

                                       35
<PAGE>

      misconduct or gross negligence or the L/C Issuer's willful failure to pay
      under any Letter of Credit after the presentation to it by the beneficiary
      of a sight draft and certificate(s) strictly complying with the terms and
      conditions of a Letter of Credit. In furtherance and not in limitation of
      the foregoing, the L/C Issuer may accept documents that appear on their
      face to be in order, without responsibility for further investigation,
      regardless of any notice or information to the contrary, and the L/C
      Issuer shall not be responsible for the validity or sufficiency of any
      instrument transferring or assigning or purporting to transfer or assign a
      Letter of Credit or the rights or benefits thereunder or proceeds thereof,
      in whole or in part, which may prove to be invalid or ineffective for any
      reason.

            (g) Applicability of ISP. Unless otherwise expressly agreed by the
      L/C Issuer and the Borrower when a Letter of Credit is issued, the rules
      of the ISP shall apply to each Letter of Credit.

            (h) Letter of Credit Fees. The Borrower shall pay to the
      Administrative Agent for the account of each Lender in accordance with its
      Revolving Pro Rata Share a letter of credit fee (the "Letter of Credit
      Fee") for each Letter of Credit equal to the Applicable Rate times the
      daily maximum amount available to be drawn under such Letter of Credit.
      Such letter of credit fees shall be computed on a quarterly basis in
      arrears. Such letter of credit fees shall be due and payable upon the
      issuance of such Letter of Credit, on each anniversary of such Letter of
      Credit thereof, on the Letter of Credit Expiration Date and thereafter, if
      applicable, on demand. If there is any change in the Applicable Rate
      during any quarter, the daily maximum amount of each Letter of Credit
      shall be computed and multiplied by the Applicable Rate separately for
      each period during such quarter that such Applicable Rate was in effect.
      Notwithstanding anything to the contrary contained herein, upon the
      request of the Required Lenders, while any Event of Default exists, all
      Letter of Credit Fees shall accrue at the Default Rate.

            (i) Fronting Fee and Documentary and Processing Charges Payable to
      L/C Issuer. In addition to the foregoing, the Borrower shall pay directly
      to the L/C Issuer for its own account the customary fronting, issuance,
      presentation, amendment, transfer, negotiation and other processing fees,
      and other standard costs and charges, of the L/C Issuer in accordance with
      the L/C Issuer's then current standard fee policy relating to letters of
      credit as from time to time in effect. Such customary fees and standard
      costs and charges are due and payable on demand and are nonrefundable.

            (j) Conflict with Issuer Documents. In the event of any conflict
      between the terms hereof and the terms of any Issuer Documents, the terms
      hereof shall control.

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

      SECTION 2.05 SWING LINE LOANS.

            (a) The Swing Line. Subject to the terms and conditions set forth
      herein, the Swing Line Lender agrees, in reliance upon the agreements of
      the other Lenders set forth in this Section 2.05, to make loans (each such
      loan, a "Swing Line Loan") to the Borrower from time to time on any
      Business Day during the Revolving Availability Period in an aggregate
      amount not to exceed at any time outstanding the amount of the Swing Line
      Sublimit, notwithstanding the fact that such Swing Line Loans, when
      aggregated with the Revolving Pro Rata Share of the Outstanding Amount of
      Revolving Loans and L/C Obligations of the Lender acting as Swing Line
      Lender, may exceed the amount of such Lender's Revolving Commitment;
      provided, however, that after giving effect to any Swing Line Loan, (i)
      the Total Revolving Outstandings shall not exceed the Aggregate Revolving
      Commitments, and (ii) the aggregate Outstanding Amount of the Revolving
      Loans of any Lender, plus such Lender's Revolving Pro Rata Share of the
      Outstanding Amount of all L/C Obligations, plus such Lender's Revolving
      Pro Rata Share of the Outstanding Amount of all Swing Line Loans shall not
      exceed such Lender's Revolving Commitment, and provided, further, that the
      Borrower shall not use the proceeds of any Swing Line Loan to refinance
      any outstanding Swing Line Loan. Within the foregoing limits, and subject
      to the other terms and conditions hereof, the Borrower may borrow under
      this Section 2.05, prepay under Section 2.06, and reborrow under this
      Section 2.05. Each Swing Line Loan shall be a Base Rate Loan. Immediately
      upon the making of a Swing Line Loan, each Lender with a Revolving
      Commitment shall be deemed to, and hereby irrevocably and unconditionally
      agrees to, purchase from the Swing Line Lender a risk participation in
      such Swing Line Loan in an amount equal to the product of such Lender's
      Revolving Pro Rata Share times the amount of such Swing Line Loan.

            (b) Borrowing Procedures. The Swing Line Lender may, in its sole
      discretion and without conferring with the Lenders, make Swing Line Loans
      by entry of credits to the Borrower's operating account or accounts with
      the Swing Line Lender to cover checks, other items and ACH debits that the
      Borrower has drawn, made or authorized against such account or accounts
      and shall notify the Administrative Agent of any overdrafts being advanced
      as Swing Line Loans. The Borrower irrevocably requests and authorizes the
      Swing Line Lender to make from time to time such Swing Line Loans by
      appropriate entry of credits sufficient to cover checks, other items and
      ACHs then presented. The Borrower acknowledges and agrees that the making
      of such Swing Line Loans is subject to the provisions of this Agreement
      other than the giving of notice as set forth below. Except as provided
      earlier in this Section 2.05(b), each Swing Line Borrowing shall be made
      upon the Borrower's irrevocable notice to the Swing Line Lender and the
      Administrative Agent, which may be given by telephone. Each such notice
      must be received by the Swing Line Lender and the Administrative Agent not
      later than 12:00 noon on the requested borrowing date, and shall specify
      (i) the amount to be borrowed, which shall be a minimum of $250,000, and
      (ii) the requested borrowing date, which shall be a Business Day. Each
      such telephonic notice must be confirmed promptly by delivery to the Swing
      Line Lender and the Administrative Agent of a written Swing Line Loan
      Notice, appropriately completed and signed by a Responsible Officer of the
      Borrower. Promptly after receipt by the Swing Line Lender of any
      telephonic Swing

                                       37
<PAGE>

      Line Loan Notice, the Swing Line Lender will confirm with the
      Administrative Agent (by telephone or in writing) that the Administrative
      Agent has also received such Swing Line Loan Notice and, if not, the Swing
      Line Lender will notify the Administrative Agent (by telephone or in
      writing) of the contents thereof. Unless the Swing Line Lender has
      received notice (by telephone or in writing) from the Administrative Agent
      (including at the request of any Lender) prior to 12:00 noon on the date
      of the proposed Swing Line Borrowing (A) directing the Swing Line Lender
      not to make such Swing Line Loan as a result of the limitations set forth
      in the proviso to the first sentence of Section 2.05(a), or (B) that one
      or more of the applicable conditions specified in Article IV is not then
      satisfied, then, subject to the terms and conditions hereof, the Swing
      Line Lender will, not later than 2:00 p.m. on the borrowing date specified
      in such Swing Line Loan Notice, make the amount of its Swing Line Loan
      available to the Borrower at its office by crediting the account of the
      Borrower on the books of the Swing Line Lender in immediately available
      funds.

            (c) Refinancing of Swing Line Loans.

                  (i) The Swing Line Lender at any time in its sole and absolute
            discretion may request, on behalf of the Borrower (which hereby
            irrevocably authorizes the Swing Line Lender to so request on its
            behalf), that each Lender with a Revolving Commitment make a Base
            Rate Loan in an amount equal to such Lender's Revolving Pro Rata
            Share of the amount of Swing Line Loans then outstanding. Such
            request shall be made in writing (which written request shall be
            deemed to be a Revolving Loan Notice for purposes hereof) and in
            accordance with the requirements of Section 2.03, without regard to
            the minimum and multiples specified therein for the principal amount
            of Base Rate Loans, but subject to the unutilized portion of the
            Aggregate Revolving Commitments and the conditions set forth in
            Section 4.02. The Swing Line Lender shall furnish the Borrower with
            a copy of the applicable Loan Notice promptly after delivering such
            notice to the Administrative Agent. Each such Lender shall make an
            amount equal to its Revolving Pro Rata Share of the amount specified
            in such Loan Notice available to the Administrative Agent in
            immediately available funds for the account of the Swing Line Lender
            at the Administrative Agent's Office not later than 1:00 p.m. on the
            day specified in such Loan Notice, whereupon, subject to Section
            2.05(c)(ii), each such 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
            Swing Line Lender.

                  (ii) If for any reason any Swing Line Loan cannot be
            refinanced by such a Borrowing in accordance with Section
            2.05(c)(i), the request for Base Rate Loans submitted by the Swing
            Line Lender as set forth herein shall be deemed to be a request by
            the Swing Line Lender that each of the Lenders with a Revolving
            Commitment fund its risk participation in the relevant Swing Line
            Loan and each such Lender's payment to the Administrative Agent for
            the account of the Swing Line Lender pursuant to Section 2.05(c)(i)
            shall be deemed payment in respect of such participation.

                                       38
<PAGE>

                  (iii) If any such Lender fails to make available to the
            Administrative Agent for the account of the Swing Line Lender any
            amount required to be paid by such Lender pursuant to the foregoing
            provisions of this Section 2.05(c) by the time specified in Section
            2.05(c)(i), the Swing Line Lender 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 Swing Line Lender at a rate per annum equal to the
            Federal Funds Rate from time to time in effect. A certificate of the
            Swing Line Lender submitted to any Lender (through the
            Administrative Agent) with respect to any amounts owing under this
            clause (iii) shall be conclusive absent manifest error.

                  (iv) Each such Lender's obligation to make Revolving Loans or
            to purchase and fund risk participations in Swing Line Loans
            pursuant to this Section 2.05(c) shall be absolute and unconditional
            and shall not be affected by any circumstance, including (A) any
            set-off, counterclaim, recoupment, defense or other right which such
            Lender may have against the Swing Line Lender, the Borrower or any
            other Person for any reason whatsoever, (B) the occurrence or
            continuance of a Default (notwithstanding anything in Section 4.02
            to the contrary), or (C) any other occurrence, event or condition,
            whether or not similar to any of the foregoing. No such funding of
            risk participations shall relieve or otherwise impair the obligation
            of the Borrower to repay Swing Line Loans, together with interest as
            provided herein.

            (d) Repayment of Participations.

                  (i) At any time after any Lender has purchased and funded a
            risk participation in a Swing Line Loan, if the Swing Line Lender
            receives any payment on account of such Swing Line Loan, the Swing
            Line Lender will distribute to such Lender its Revolving Pro Rata
            Share of such payment (appropriately adjusted, in the case of
            interest payments, to reflect the period of time during which such
            Lender's risk participation was funded) in the same funds as those
            received by the Swing Line Lender.

                  (ii) If any payment received by the Swing Line Lender in
            respect of principal or interest on any Swing Line Loan is required
            to be returned by the Swing Line Lender under any of the
            circumstances described in Section 10.06 (including pursuant to any
            settlement entered into by the Swing Line Lender in its discretion),
            each Lender shall pay to the Swing Line Lender its Revolving Pro
            Rata Share thereof on demand of the Administrative Agent, plus
            interest thereon from the date of such demand to the date such
            amount is returned, at a rate per annum equal to the Federal Funds
            Rate. The Administrative Agent will make such demand upon the
            request of the Swing Line Lender. The obligations of the Lenders
            under this clause shall survive the payment in full of the
            Obligations and the termination of this Agreement.

                                       39
<PAGE>

            (e) Interest for Account of Swing Line Lender. The Swing Line Lender
      shall be responsible for invoicing the Borrower for interest on the Swing
      Line Loans. Until each Lender funds its Base Rate Loan or risk
      participation pursuant to this Section 2.05 to refinance such Lender's
      Revolving Pro Rata Share of any Swing Line Loan, interest in respect of
      such Pro Rata Share shall be solely for the account of the Swing Line
      Lender.

            (f) Payments Directly to Swing Line Lender. The Borrower shall make
      all payments of principal and interest in respect of the Swing Line Loans
      directly to the Swing Line Lender.

      SECTION 2.06 PREPAYMENTS.

            (a) Positive collected balances in the Borrower's operating accounts
      at Wells Fargo at the end of each Business Day will reduce any Base Rate
      Loans that are Revolving Loans. In addition, the Borrower may, upon notice
      to the Administrative Agent, at any time or from time to time voluntarily
      prepay Revolving Loans or Term 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 11:00 a.m. (A) three Business Days
      prior to any date of prepayment of LIBOR Loans and (B) on the date of
      prepayment of Base Rate Loans; (ii) any prepayment of LIBOR Loans shall be
      in a principal amount of $5,000,000 or a whole multiple of $1,000,000 in
      excess thereof; and (iii) any prepayment of Base Rate Loans (other than
      Swing Line Loans) shall be in a principal amount of $500,000 or a whole
      multiple of $100,000 in excess thereof or, in each case, if less, the
      entire principal amount thereof then outstanding. Each such notice shall
      specify the date and amount of such prepayment and the Type(s) of Loans to
      be prepaid and whether such Loan is a Revolving Loan or a Term Loan. The
      Administrative Agent will promptly notify each Lender of its receipt of
      each such notice, and of the amount of such Lender's Pro Rata Share of
      such prepayment. If such notice is given by the Borrower, the Borrower
      shall make such prepayment and the payment amount specified in such notice
      shall be due and payable on the date specified therein. Any prepayment of
      a Base Rate Loan or LIBOR Loan shall be accompanied by all accrued
      interest thereon, and as applicable, together with any additional amounts
      required pursuant to Section 3.05. Each such prepayment shall be applied
      to the Revolving Loans or the Term Loans, as the case may be, of the
      Lenders in accordance with their respective Pro Rata Shares of such Loan.
      Any voluntary prepayments of the Term Loans shall be applied in inverse
      order of maturity.

            (b) The Borrower may, upon notice to the Swing Line Lender (with a
      copy to the Administrative Agent), at any time or from time to time,
      voluntarily prepay Swing Line Loans in whole or in part without premium or
      penalty; provided that such notice must be received by the Swing Line
      Lender and the Administrative Agent not later than 12:00 noon on the date
      of the prepayment. Each such notice shall specify the date and amount 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.

                                       40
<PAGE>

            (c) If for any reason the Total Revolving Outstandings at any time
      exceed the Aggregate Revolving Commitments then in effect, the Borrower
      shall immediately prepay Revolving Loans and/or Cash Collateralize the L/C
      Obligations in an aggregate amount equal to such excess; provided,
      however, that the Borrower shall not be required to Cash Collateralize the
      L/C Obligations pursuant to this Section 2.06(c) unless after the
      prepayment in full of the Revolving Loans and Swing Line Loans the Total
      Revolving Outstandings exceed the Aggregate Revolving Commitments then in
      effect.

            (d) Concurrently with the receipt of Net Cash Proceeds from the
      Disposition by the Borrower or any of its Subsidiaries pursuant to Section
      7.05(g), the Borrower shall prepay the Loans in an aggregate principal
      amount equal to 100% of such Net Cash Proceeds to the extent that such
      amount exceeds $5,000,000 in the aggregate for all Dispositions that have
      occurred during any Fiscal Year. Each such mandatory prepayment shall be
      made and applied as provided in Section 2.06(f).

            (e) Concurrently with the receipt of Net Cash Proceeds from any
      Equity Issuance of the Borrower or any of its Subsidiaries, the Borrower
      shall prepay the Loans in an aggregate amount equal to 50% of such Net
      Cash Proceeds. Each such mandatory prepayment shall be made and applied as
      provided in Section 2.06(f).

            (f) Any mandatory prepayment of Term Loans pursuant to Section
      2.06(d) or (e), shall (i) include and be applied to interest to the date
      of such prepayment on the principal amount prepaid and include any
      additional amounts required pursuant to Section 3.05, (ii) not be subject
      to any notice and minimum payment provisions and (iii) be applied to the
      Term Loan in inverse order of maturity, which payments shall be in
      addition to the unpaid scheduled installment payments of the Term Loans,
      and if the Term Loans have been repaid, in full, then to the Revolving
      Loans (without a corresponding reduction in the Aggregate Revolving
      Commitments), and if no Revolving Loans are then outstanding, to Cash
      Collateralize outstanding Letters of Credit and any Swap Obligations.

      SECTION 2.07 TERMINATION OR REDUCTION OF COMMITMENTS. The Borrower may,
upon notice to the Administrative Agent, terminate the Aggregate Revolving
Commitments, or from time to time permanently reduce the Aggregate Revolving
Commitments; provided that (i) any such notice shall be received by the
Administrative Agent not later than 11:00 a.m. five Business Days prior to the
date of termination or reduction, (ii) any such partial reduction shall be in an
aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess
thereof, (iii) the Borrower shall not terminate or reduce the Aggregate
Revolving Commitments if, after giving effect thereto and to any concurrent
prepayments hereunder, the Total Revolving Outstandings and Outstanding Amount
of Swing Line Loans would exceed the Aggregate Revolving Commitments, and (iv)
if, after giving effect to any reduction of the Aggregate Revolving Commitments,
the Letter of Credit Sublimit or the Swing Line Sublimit exceeds the amount of
the Aggregate Revolving Commitments, such Sublimit shall be automatically
reduced by the amount of such excess. The Administrative Agent will promptly
notify the Lenders of any such notice of termination or reduction of the
Aggregate Revolving Commitments. Any reduction of the Aggregate Revolving
Commitments shall be applied to the Revolving Commitment of each Lender
according to its Revolving Pro Rata Share. All Revolving Commitment Fees accrued

                                       41
<PAGE>

until the effective date of any termination of the Aggregate Revolving
Commitments shall be paid on the effective date of such termination.

      SECTION 2.08 REPAYMENT OF LOANS.

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

            (b) The Borrower shall repay each Swing Line Loan on the earlier to
      occur of (i) the date demand is made by Swing Line Lender for repayment of
      such Loan and (ii) the Revolving Maturity Date.

            (c) To the extent not otherwise required to be paid earlier as
      provided herein, the Borrower shall repay the principal of the Term Loans
      on each payment date and on the Term Maturity Date in such amounts as set
      forth next to each such date set forth below (subject to reduction after
      taking into account any prepayment of the Term Loans pursuant to Section
      2.06):

</TABLE>

      SECTION 2.09 INTEREST.

            (a) Subject to the provisions of subsection (b) below, (i) each
      LIBOR Loan shall bear interest on the outstanding principal amount thereof
      for each Interest Period at a rate per annum equal to the lesser of (y)
      the Highest Lawful Rate or (z) LIBOR for such Interest Period plus the
      Applicable Rate for LIBOR Loans; (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 lesser of (y) the Highest
      Lawful Rate or (z) the Base Rate plus the Applicable Rate for Base Rate
      Loans; and (iii) each Swing Line Loan shall bear interest on the
      outstanding principal amount thereof from the applicable borrowing date at
      a rate per annum equal to the lesser of (y) the Highest Lawful Rate or (z)
      the Base Rate plus the Applicable Rate for Base Rate Loans.

      (b)   (i) If any amount of principal of any Loan is not paid when due
      (without regard to any applicable grace periods), whether at stated
      maturity, by acceleration or otherwise, such amount shall thereafter bear
      interest at a fluctuating interest rate per annum at all times equal to
      the lesser of (y) the Default Rate and (z) the Highest Lawful Rate, to the
      fullest extent permitted by Applicable Laws.

                  (ii) If any amount (other than principal of any Loan) payable
            by the Borrower under any Loan Document is not paid when due
            (without regard to any applicable grace periods), whether at stated
            maturity, by acceleration or otherwise, then upon the request of the
            Required Lenders, such amount shall thereafter bear interest at a
            fluctuating interest rate per annum at all times equal to the lesser
            of (y) the Default Rate and (z) the Highest Lawful Rate, to the
            fullest extent permitted by Applicable Laws.

                  (iii) Upon the request of the Required Lenders, while any
            Event of Default exists, the Borrower shall pay interest on the
            principal amount of all outstanding Obligations hereunder at a
            fluctuating interest rate per annum at all times equal to the lesser
            of (y) the Default Rate and (z) the Highest Lawful Rate, to the
            fullest extent permitted by Applicable Laws.

<PAGE>

                  (iv) Accrued and unpaid interest on past due amounts
            (including interest on past due interest) shall be due and payable
            upon demand.

            (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 subsections
(h) and (i) of Section 2.04:

            (a) The Borrower shall pay to the Administrative Agent for the
      account of each Lender with a Revolving Commitment in accordance with its
      Revolving Pro Rata Share, a commitment fee (the "Revolving Commitment
      Fee") equal to the Applicable Rate times the actual daily amount by which
      the Aggregate Revolving Commitments exceed the sum of (i) the Outstanding
      Amount of Revolving Loans and (ii) the Outstanding Amount of L/C
      Obligations. The Revolving Commitment Fee shall accrue at all times during
      the Revolving Availability Period, including at any time during which one
      or more of the conditions in Article IV is not met, and shall be due and
      payable quarterly in arrears on the last Business Day of each March, June,
      September and December, commencing with the first such date to occur after
      the Closing Date, and on the Revolving Maturity Date. The Revolving
      Commitment Fee shall be calculated quarterly in arrears, and if there is
      any change in the Applicable Rate during any quarter, the actual daily
      amount shall be computed and multiplied by the Applicable Rate separately
      for each period during such quarter that such Applicable Rate was in
      effect.

            (b) The Borrower shall pay to the Administrative Agent for its own
      account fees in the amounts and at the times specified in the Fee Letter.
      Such fees shall be fully earned when paid and shall not be refundable for
      any reason whatsoever.

      SECTION 2.11 COMPUTATION OF INTEREST AND FEES. All computations of
interest for Base Rate Loans when the Base Rate is determined by the Prime Rate
shall be made on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed. All other computations of fees and interest shall be made
on the basis of a 360-day year and actual days elapsed (which results in more
fees or interest, as applicable, being paid than if computed on the basis of a
365-day year). Interest shall accrue on each Loan for the day on which the Loan
is made, and shall not accrue on a Loan, or any portion thereof, for the day on
which the Loan or such portion is paid, provided that any Loan that is repaid on
the same day on which it is made shall, subject to Section 2.13(a), bear
interest for one day. Each determination by the Administrative Agent of an
interest rate or fee hereunder shall be conclusive and binding for all purposes,
absent manifest error.

      SECTION 2.12 EVIDENCE OF DEBT.

            (a) The Credit Extensions made by each Lender shall be evidenced by
      one or more accounts or records maintained by such Lender and by the
      Administrative Agent in

                                       44
<PAGE>

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

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

      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 on the date specified herein. The
      Administrative Agent will promptly distribute to each Lender its
      applicable Pro Rata Share (or other applicable share as provided herein)
      of such payment in like funds as received by wire transfer to such
      Lender's Lending Office. All payments received by the Administrative Agent
      after 12:00 noon shall be deemed received on the next succeeding Business
      Day and any applicable interest or fee shall continue to accrue. 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. Notwithstanding the foregoing, the
      Administrative Agent is hereby authorized to effect terms of payments due
      under this Agreement and the Notes by debiting the Borrower's account(s)
      with the Administrative Agent. This authorization shall not affect the
      obligation of the Borrower to pay such sums when due, without notice, if
      there are insufficient funds in such account to make such payment in full
      on the due date thereof, or if the Administrative Agent fails to debit the
      account(s).

                                       45
<PAGE>

            (b) (i) Unless the Administrative Agent shall have received notice
      from a Lender prior to the proposed date of any Borrowing that such Lender
      will not make available to the Administrative Agent such Lender's share of
      such Borrowing, the Administrative Agent may assume that such Lender has
      made such share available on such date in accordance with Section 2.03 and
      may, in reliance upon such assumption, make available to the Borrower a
      corresponding amount. In such event, if a Lender has not in fact made its
      share of the applicable Borrowing available to the Administrative Agent,
      then the applicable Lender and the Borrower severally agree to pay to the
      Administrative Agent forthwith on demand such corresponding amount in
      immediately available funds with interest thereon, for each day from and
      including the date such amount is made available to the Borrower to but
      excluding the date of payment to the Administrative Agent, at (A) in the
      case of a payment to be made by such Lender, the greater of the Federal
      Funds Rate and a rate determined by the Administrative Agent in accordance
      with banking industry rules on interbank compensation and (B) in the case
      of a payment to be made by the Borrower, the interest rate applicable to
      Base Rate Loans. If the Borrower and such Lender shall pay such interest
      to the Administrative Agent for the same or an overlapping period, the
      Administrative Agent shall promptly remit to the Borrower the amount of
      such interest paid by the Borrower for such period. If such Lender pays
      its share of the applicable Borrowing to the Administrative Agent, then
      the amount so paid shall constitute such Lender's Loan included in such
      Borrowing. Any payment by the Borrower shall be without prejudice to any
      claim the Borrower may have against a Lender that shall have failed to
      make such payment to the Administrative Agent. 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:

            (ii) Unless the Administrative Agent shall have received notice from
      the Borrower prior to the date on which any payment is due to the
      Administrative Agent for the account of the Lenders or the L/C Issuer
      hereunder that the Borrower will not make such payment, the Administrative
      Agent may assume that the Borrower has made such payment on such date in
      accordance herewith and may, in reliance upon such assumption, distribute
      to the Lenders or the L/C Issuer, as the case may be, the amount due. In
      such event, if the Borrower has not in fact made such payment, then each
      of the Lenders or the L/C Issuer, as the case may be, severally agrees to
      repay to the Administrative Agent forthwith on demand the amount so
      distributed to such Lender or the L/C Issuer, in immediately available
      funds with interest thereon, for each day from and including the date such
      amount is distributed to it to but excluding the date of payment to the
      Administrative Agent, at the greater of the Federal Funds Rate and a rate
      determined by the Administrative Agent in accordance with banking industry
      rules on interbank compensation.

                                       46
<PAGE>

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

            (c) If any Lender makes available to the Administrative Agent funds
      for any Loan to be made by such Lender as provided in the foregoing
      provisions of this Article II, and such funds are not made available to
      the Borrower by the Administrative Agent because the conditions to the
      applicable Credit Extension set forth in Article 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.

            (d) The obligations of the Lenders hereunder to make Revolving
      Loans, to fund participations in Letters of Credit and Swing Line Loans
      and to make payments pursuant to Section 10.04(c) are several and not
      joint. The failure of any Lender to make any Revolving Loan, to fund any
      such participation or to make any payment under Section 10.04(c) 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 Revolving
      Loan, to purchase its participation or to make its payment under Section
      10.04(c).

            (e) 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 any Lender shall, by exercising any
right of setoff or counterclaim or otherwise, obtain payment in respect of any
principal of or interest on any of the Loans made by it, or the participations
in L/C Obligations or in Swing Line Loans held by it resulting in such Lender's
receiving payment of a proportion of the aggregate amount of such Loans or
participations and accrued interest thereon greater than its Pro Rata Share
thereof as provided herein, then the Lender receiving such greater proportion
shall (a) notify the Administrative Agent of such fact, and (b) purchase (for
cash at face value) participations in the applicable Loans and subparticipations
in L/C Obligations and Swing Line Loans of the other Lenders, or make such other
adjustments as shall be equitable, so that the benefit of all such payments
shall be shared by the Lenders ratably in accordance with the aggregate amount
of principal of and accrued interest on their respective Loans and other amounts
owing them, provided that:

            (a) if any such participations or subparticipations are purchased
      and all or any portion of the payment giving rise thereto is recovered,
      such participations or subparticipations shall be rescinded and the
      purchase price restored to the extent of such recovery, without interest;
      and

            (b) the provisions of this Section shall not be construed to apply
      to (x) any payment made by the Borrower pursuant to and in accordance with
      the express terms of this Agreement or (y) any payment obtained by a
      Lender as consideration for the assignment of or sale of a participation
      in any of its Loans or subparticipations in L/C

                                       47
<PAGE>

      Obligations or Swing Line Loans to any assignee or participant, other than
      to the Borrower or any Subsidiary thereof (as to which the provisions of
      this Section shall apply).

      Each Loan Party consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against such
Loan Party rights of setoff and counterclaim with respect to such participation
as fully as if such Lender were a direct creditor of such Loan Party in the
amount of such participation.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

      SECTION 3.01 TAXES.

            (a) Any and all payments by or on account of any obligation of the
      Borrower hereunder or under any other Loan Document shall be made free and
      clear of and without reduction or withholding for any Indemnified Taxes or
      Other Taxes, provided that if the Borrower shall be required by applicable
      law to deduct any Indemnified Taxes (including any Other Taxes) from such
      payments, then (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,
      Lender or L/C Issuer, as the case may be, receives an amount equal to the
      sum it would have received had no such deductions been made, (ii) the
      Borrower shall make such deductions and (iii) the Borrower shall timely
      pay the full amount deducted to the relevant Governmental Authority in
      accordance with applicable law.

            (b) Without limiting the provisions of subsection (a) above, the
      Borrower shall timely pay any Other Taxes to the relevant Governmental
      Authority in accordance with applicable law.

            (c) The Borrower shall indemnify the Administrative Agent, each
      Lender and the L/C Issuer, within 10 days after demand therefor, for the
      full amount of any Indemnified Taxes or Other Taxes (including Indemnified
      Taxes or Other Taxes imposed or asserted on or attributable to amounts
      payable under this Section) paid by the Administrative Agent, such Lender
      or the L/C Issuer, as the case may be, and any penalties, interest and
      reasonable expenses arising therefrom or with respect thereto, whether or
      not such Indemnified Taxes or Other Taxes were correctly or legally
      imposed or asserted by the relevant Governmental Authority. A certificate
      as to the amount of such payment or liability delivered to the Borrower by
      a Lender or the L/C Issuer (with a copy to the Administrative Agent), or
      by the Administrative Agent on its own behalf or on behalf of a Lender or
      the L/C Issuer, shall be conclusive absent manifest error.

            (d) As soon as practicable after any payment of Indemnified Taxes or
      Other Taxes by the Borrower to a Governmental Authority, the Borrower
      shall deliver to the Administrative Agent the original or a certified copy
      of a receipt issued by such Governmental Authority evidencing such
      payment, a copy of the return reporting such

                                       48
<PAGE>

      payment or other evidence of such payment reasonably satisfactory to the
      Administrative Agent.

            (e) Any Foreign Lender that is entitled to an exemption from or
      reduction of withholding tax under the law of the jurisdiction in which
      the Borrower is resident for tax purposes, or any treaty to which such
      jurisdiction is a party, with respect to payments hereunder or under any
      other Loan Document shall deliver to the Borrower (with a copy to the
      Administrative Agent), at the time or times prescribed by applicable law
      or reasonably requested by the Borrower or the Administrative Agent, such
      properly completed and executed documentation prescribed by applicable law
      as will permit such payments to be made without withholding or at a
      reduced rate of withholding. In addition, any Lender, if requested by the
      Borrower or the Administrative Agent, shall deliver such other
      documentation prescribed by applicable law or reasonably requested by the
      Borrower or the Administrative Agent as will enable the Borrower or the
      Administrative Agent to determine whether or not such Lender is subject to
      backup withholding or information reporting requirements.

      Without limiting the generality of the foregoing, in the event that the
Borrower is resident for tax purposes in the United States, any Foreign Lender
shall deliver to the Borrower and the Administrative Agent (in such number of
copies as shall be requested by the recipient) on or prior to the date on which
such Foreign Lender becomes a Lender under this Agreement (and from time to time
thereafter upon the request of the Borrower or the Administrative Agent, but
only if such Foreign Lender is legally entitled to do so), whichever of the
following is applicable:

                  (i) duly completed copies of Internal Revenue Service Form
            W-8BEN claiming eligibility for benefits of an income tax treaty to
            which the United States is a party,

                  (ii) duly completed copies of Internal Revenue Service Form
            W-8ECI,

                  (iii) in the case of a Foreign Lender claiming the benefits of
            the exemption for portfolio interest under section 881(c) of the
            Code, (x) a certificate to the effect that such Foreign Lender is
            not (A) a "bank" within the meaning of section 881(c)(3)(A) of the
            Code, (B) a "10 percent shareholder" of the Borrower within the
            meaning of section 881(c)(3)(B) of the Code, or (C) a "controlled
            foreign corporation" described in section 881(c)(3)(C) of the Code
            and (y) duly completed copies of Internal Revenue Service Form
            W-8BEN, or

                  (iv) any other form prescribed by applicable law as a basis
            for claiming exemption from or a reduction in United States Federal
            withholding tax duly completed together with such supplementary
            documentation as may be prescribed by applicable law to permit the
            Borrower to determine the withholding or deduction required to be
            made.

            (f) If the Administrative Agent, any Lender or the L/C Issuer
      determines, in its sole discretion, that it has received a refund of any
      Taxes or Other Taxes as to which it has been indemnified by the Borrower
      or with respect to which the Borrower has paid

                                       49
<PAGE>

      additional amounts pursuant to this Section, it shall pay to the Borrower
      an amount equal to such refund (but only to the extent of indemnity
      payments made, or additional amounts paid, by the Borrower under this
      Section with respect to the Taxes or Other Taxes giving rise to such
      refund), net of all out-of-pocket expenses of the Administrative Agent,
      such Lender or the L/C Issuer, as the case may be, and without interest
      (other than any interest paid by the relevant Governmental Authority with
      respect to such refund), provided that the Borrower, upon the request of
      the Administrative Agent, such Lender or the L/C Issuer, agrees to repay
      the amount paid over to the Borrower (plus any penalties, interest or
      other charges imposed by the relevant Governmental Authority) to the
      Administrative Agent, such Lender or the L/C Issuer in the event the
      Administrative Agent, such Lender or the L/C Issuer is required to repay
      such refund to such Governmental Authority. This subsection shall not be
      construed to require the Administrative Agent, any Lender or the L/C
      Issuer to make available its tax returns (or any other information
      relating to its taxes that it deems confidential) to the Borrower or any
      other Person.

      SECTION 3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund LIBOR
Loans, or to determine or charge interest rates based upon LIBOR or any
Governmental Authority has imposed material restrictions on the authority of
such Lender to purchase or sell, or to take deposits of, Dollars in the London
interbank market (in each case, such Law, assertion or imposition being made or
adopted after the date such Lender became a party to this Agreement), then, on
notice thereof by such Lender to the Borrower through the Administrative Agent,
any obligation of such Lender to make or continue LIBOR Loans or to convert Base
Rate Loans to LIBOR 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 LIBOR Loans of such Lender to Base Rate Loans,
either on the last day of the Interest Period therefor, if such Lender may
lawfully continue to maintain such LIBOR Loans to such day, or immediately, if
such Lender may not lawfully continue to maintain such LIBOR Loans. Upon any
such prepayment or conversion, the Borrower shall also pay accrued interest on
the amount so prepaid or converted.

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

      SECTION 3.04 INCREASED COST AND REDUCED RETURN; CAPITAL ADEQUACY; RESERVES
ON LIBOR LOANS.

            (a) If any Change in Law shall:

                  (i) impose, modify or deem applicable any reserve, special
            deposit, compulsory loan, insurance charge or similar requirement
            against assets of, deposits with or for the account of, or credit
            extended or participated in by, any Lender (except any reserve
            requirement contemplated by Section 3.04(e) or the L/C Issuer;

                  (ii) subject any Lender or the L/C Issuer to any tax of any
            kind whatsoever with respect to this Agreement, any Letter of
            Credit, any participation in a Letter of Credit or any LIBOR Loan
            made by it, or change the basis of taxation of payments to such
            Lender or the L/C Issuer in respect thereof (except for Indemnified
            Taxes or Other Taxes covered by Section 3.01 and the imposition of,
            or any change in the rate of, any Excluded Tax payable by such
            Lender or the L/C Issuer); or

                  (iii) impose on any Lender or the L/C Issuer or the London
            interbank market any other condition, cost or expense affecting this
            Agreement or LIBOR Loans made by such Lender or any Letter of Credit
            or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation
to make any such Loan), or to increase the cost to such Lender or the L/C Issuer
of participating in, issuing or maintaining any Letter of Credit (or of
maintaining its obligation to participate in or to issue any Letter of Credit),
or to reduce the amount of any sum received or receivable by such Lender or the
L/C Issuer hereunder (whether of principal, interest or any other amount) then,
upon request of such Lender or the L/C Issuer, the Borrower will pay to such
Lender or the L/C Issuer, as the case may be, such additional amount or amounts
as will compensate such Lender or the L/C Issuer, as the case may be, for such
additional costs incurred or reduction suffered.

            (b) If any Lender or the L/C Issuer determines that any Change in
      Law affecting such Lender or the L/C Issuer or any Lending Office of such
      Lender or such Lender's or the L/C Issuer's holding company, if any,
      regarding capital requirements has or would have the effect of reducing
      the rate of return on such Lender's or the L/C Issuer's capital or on the
      capital of such Lender's or the L/C Issuer's holding company, if any, as a
      consequence of this Agreement, the Revolving Commitments of such Lender or
      the Loans made by, or participations in Letters of Credit held by, such
      Lender, or the Letters of Credit issued by the L/C Issuer, to a level
      below that which such Lender or the L/C Issuer or such Lender's or the L/C
      Issuer's holding company could have achieved but for such Change in Law
      (taking into consideration such Lender's or the L/C Issuer's policies and
      the policies of such Lender's or the L/C Issuer's holding company with
      respect to capital adequacy), then from time to time the Borrower will pay
      to such Lender or the L/C Issuer, as the case may be, such additional
      amount or amounts as will

                                       51
<PAGE>

      compensate such Lender or the L/C Issuer or such Lender's or the L/C
      Issuer's holding company for any such reduction suffered.

            (c) A certificate of a Lender or the L/C Issuer setting forth the
      amount or amounts necessary to compensate such Lender or the L/C Issuer or
      its holding company, as the case may be, as specified in subsection (a) or
      (b) of this Section and delivered to the Borrower shall be conclusive
      absent manifest error. The Borrower shall pay such Lender or the L/C
      Issuer, as the case may be, the amount shown as due on any such
      certificate within 10 days after receipt thereof.

            (d) The Borrower shall pay to each Lender, as long as such Lender
      shall be required to maintain reserves with respect to liabilities or
      assets consisting of or including Eurocurrency funds or deposits
      (currently known as "Eurocurrency liabilities"), additional interest on
      the unpaid principal amount of each LIBOR Loan equal to the actual costs
      of such reserves allocated to such Loan by such Lender (as determined by
      such Lender in good faith, which determination shall be conclusive), which
      shall be due and payable on each date on which interest is payable on such
      Loan, provided the Borrower shall have received at least 10 days' prior
      notice (with a copy to the Administrative Agent) of such additional
      interest from such Lender. If a Lender fails to give notice 10 days prior
      to the relevant Interest Payment Date, such additional interest shall be
      due and payable 10 days from receipt of such notice.

            (e) Failure or delay on the part of any Lender or the L/C Issuer to
      demand compensation pursuant to the foregoing provisions of this Section
      shall not constitute a waiver of such Lender's or the L/C Issuer's right
      to demand such compensation, provided that the Borrower shall not be
      required to compensate a Lender or the L/C Issuer pursuant to the
      foregoing provisions of this Section for any increased costs incurred or
      reductions suffered more than nine months prior to the date that such
      Lender or the L/C Issuer, as the case may be, notifies the Borrower of the
      Change in Law giving rise to such increased costs or reductions and of
      such Lender's or the L/C Issuer's intention to claim compensation therefor
      (except that, if the Change in Law giving rise to such increased costs or
      reductions is retroactive, then the nine-month period referred to above
      shall be extended to include the period of retroactive effect thereof).

      SECTION 3.05 COMPENSATION FOR 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);

                                       52
<PAGE>

            (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 LIBOR 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 10.16;

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.

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

      SECTION 3.06 MITIGATION OBLIGATIONS; REPLACEMENT OF LENDERS.

            (a) If any Lender requests compensation under Section 3.04, or the
      Borrower is required to pay any additional amount to any Lender or any
      Governmental Authority for the account of any Lender pursuant to Section
      3.01, or if any Lender gives a notice pursuant to Section 3.02, then such
      Lender shall use reasonable efforts to designate a different Lending
      Office for funding or booking its Loans hereunder or to assign its rights
      and obligations hereunder to another of its offices, branches or
      affiliates, if, in the judgment of such Lender, such designation or
      assignment (i) would eliminate or reduce amounts payable pursuant to
      Section 3.01 or 3.04, as the case may be, in the future, or eliminate the
      need for the notice pursuant to Section 3.02, as applicable, and (ii) in
      each case, would not subject such Lender to any unreimbursed cost or
      expense and would not otherwise be disadvantageous to such Lender. The
      Borrower hereby agrees to pay all reasonable costs and expenses incurred
      by any Lender in connection with any such designation or assignment.

            (b) If any Lender requests compensation under Section 3.04, or if
      the Borrower is required to pay any additional amount to any Lender or any
      Governmental Authority for the account of any Lender pursuant to Section
      3.01, or if any Lender gives notice under Section 3.02 which remains in
      effect, the Borrower may replace such Lender in accordance with Section
      10.13.

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

interests in, all real property necessary or used in the ordinary conduct of its
business, except for such defects in title as could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. The
property of the Borrower and its Subsidiaries is subject to no Liens, other than
Liens permitted by Section 7.01.

      SECTION 5.09 ENVIRONMENTAL COMPLIANCE. 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 such Environmental Laws and claims could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

      SECTION 5.10 INSURANCE. The properties and businesses of the Borrower and
its Subsidiaries are insured with financially sound and reputable insurance
companies not Affiliates of the Borrower, in such amounts, with such deductibles
and covering such risks as are customarily carried by companies of similar size
engaged in similar businesses and owning similar properties in localities where
the Borrower or the applicable Subsidiary operates.

Federal tax returns and all other material tax returns and reports required to
be filed, and have paid all Federal and all other material taxes, assessments,

being contested in good faith by appropriate proceedings diligently conducted
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.

            (a) Each Plan is in compliance in all material respects with the
      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 is
      so qualified, and nothing has occurred which would prevent, or cause the
      loss of, such qualification. The Borrower and each ERISA Affiliate have
      made all required contributions to each Plan subject to Section 412 of the
      Code, and no application for a funding waiver or an extension of any
      amortization period pursuant to Section 412 of the Code has been made with
      respect to any Plan.

            (b) There are no pending or, to the best knowledge of the Borrower,
      material threatened claims, actions or lawsuits, or material action by any
      Governmental Authority, with respect to any Plan that could reasonably be
      expected to have a Material Adverse Effect. There has been no prohibited
      transaction or violation of the fiduciary

                                       59
<PAGE>

      responsibility rules with respect to any Plan that has resulted or could
      reasonably be expected to result in a Material Adverse Effect.

      occur, (ii) no Pension Plan has any Unfunded Pension Liability, (iii)
      neither the Borrower nor any ERISA Affiliate has incurred, or reasonably

      4007 of ERISA), (iv) neither the Borrower nor any ERISA Affiliate has
      incurred, or reasonably expects to incur, any liability (and no event has
      occurred which, with the giving of notice under Section 4219 of ERISA,
      would result in such liability) under Sections 4201 or 4243 of ERISA with
      respect to a Multiemployer Plan, and (v) neither the Borrower nor any
      ERISA Affiliate has engaged in a transaction that could be subject to
      Sections 4069 or 4212(c) of ERISA.

      SECTION 5.13 SUBSIDIARIES. As of the Closing Date, the Borrower has no
Subsidiaries other than those specifically disclosed in Part (a) of Schedule

such Subsidiaries have been validly issued, are fully paid and nonassessable and
are owned by a Loan Party in the amounts specified on Part (a) of Schedule 5.13
free and clear of all Liens. As of the Closing Date, the Borrower has no equity
investments in any other corporation or entity other than those specifically

in the Borrower have been validly issued and are fully paid and nonassessable.

      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
      FRB), 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. The Borrower has disclosed to the Administrative
Agent and the Lenders all agreements, instruments and corporate or other
restrictions to which it or any of its Subsidiaries is subject, and all other
matters known to it, that, individually or in the aggregate, could reasonably be
expected to result in a Material Adverse Effect. No report, financial statement,
certificate or other written information furnished by or on behalf of any Loan
Party to the Administrative Agent or any Lender in connection with the
transactions contemplated hereby and the negotiation of this Agreement or
delivered hereunder (as modified or supplemented by

                                       60
<PAGE>

other information so furnished), when taken as a whole, contains any material
misstatement of fact or omits to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading in any material respect; provided that, with respect to
projected financial information, the Borrower represents only that such
information was prepared in good faith based upon assumptions believed to be
reasonable at the time, it being acknowledged that such financial information as
it relates to future events is not to be viewed as fact and that actual results
during the period or periods covered by such financial information may differ
from the projected results set forth therein by a material amount.

      SECTION 5.16 COMPLIANCE WITH LAWS. Each of the Borrower and each
Subsidiary is in compliance in all material respects with the requirements of
all Laws and all orders, writs, injunctions and decrees applicable to it or to
its properties, except in such instances in which (a) such requirement of Law or
order, writ, injunction or decree is being contested in good faith by
appropriate proceedings diligently conducted or (b) the failure to comply
therewith, either individually or in the aggregate, could not reasonably be
expected to have a Material Adverse Effect.

      SECTION 5.17 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 intellectual property rights (collectively, "IP Rights") that are
reasonably necessary for the operation of their respective businesses, without
conflict with the rights of any other Person except as could not reasonably be
expected to have a Material Adverse Effect. 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 except as could not reasonably be expected to have a Material
Adverse Effect. No claim or Litigation regarding any of the foregoing is pending
or, to the best knowledge of the Borrower, threatened, which, either
individually or in the aggregate, could reasonably be expected to have a
Material Adverse Effect.

      SECTION 5.18 BUSINESSES. As of the Closing Date, the Borrower is presently
engaged directly or through wholly-owned Subsidiaries in the business of the
extraction of high quality limestone from its quarries and the processing for
sale and sale of pulverized limestone, quicklime hydrated lime, and other
related products.

      SECTION 5.19 COMMON ENTERPRISE. The Borrower and its Subsidiaries are
engaged in the businesses set forth in Section 5.18 as of the Closing Date.
These operations require financing on a basis such that the credit supplied can
be made available from time to time to the Borrower and various of its
Subsidiaries, as required for the continued successful operation of the Borrower
and its Subsidiaries as a whole. The Borrower has requested the Lender to make
credit available hereunder primarily for the purposes set forth in Section 6.12
and generally for the purposes of financing the operations of the Borrower and
its Subsidiaries. The Borrower and each of its Subsidiaries expects to derive
benefit (and the Board of Directors (or other similar governing body) of the
Borrower and each of its Subsidiaries has determined that such Subsidiary may
reasonably be expected to derive benefit), directly or indirectly, from a
portion of the credit extended by the Lenders hereunder, both in its separate
capacity and as a member of the group of companies, since the successful
operation and condition of the Borrower and each

                                       61
<PAGE>

of its Subsidiaries is dependent on the continued successful performance of the
functions of the group as a whole. The Borrower acknowledges that, but for the
agreement by each of the Guarantors to execute and deliver the Guaranty, the
Administrative Agent and the Lenders would not have made available the credit
facilities established hereby on the terms set forth herein.

      SECTION 5.20 SOLVENT. The Borrower is, and the Borrower and its
Subsidiaries are on a consolidated basis, Solvent.

      SECTION 5.21 REAL ESTATE COLLATERAL. Except as disclosed in Schedule 5.21,
as the same may have been supplemented, to the best of the Borrower's knowledge
after due inquiry, (i) as of the date hereof, no Loan Party has received any
claim for, or paid any, royalties, fees or other payments for the extraction of
oil, gas, or other hydrocarbons, limestone, gravel, crushed rock, sand or other
minerals of any kind or character over, under or produced from any Collateral,
and (ii) none of the mineral rights reserved or conveyed to third parties listed
on Schedule 5.21, has interfered in any material respect with the operations of
any Loan Party's business.

      SECTION 5.22 NOTIFICATION OF AGREEMENT. The Borrower has sufficiently
notified all holders of the Phase II Debt of the effectiveness of this Agreement
and the other Loan Documents so that the Administrative Agent is entitled to
receive all notices of default under the Phase II Debt Documents.

                                   ARTICLE VI.

shall remain outstanding, the Borrower shall, and shall (except in the case of
the covenants set forth in Sections 6.01, 6.02, 6.03 and 6.11) cause each

      projected income statement, statement of cash flows and balance sheet and
      a report containing management's discussion and analysis of such
      projections, accompanied by a certificate from the principal financial and
      accounting officer of each of the Borrowers to the effect that, to the
      best of such officer's knowledge, such projections are good faith

the requirements of all Laws and all orders, writs, injunctions and decrees
applicable to it or to its business or property, except in such instances in

      SECTION 6.09 BOOKS AND RECORDS. (a) Maintain proper books of record and

respect of which such disclosure is then prohibited by law or any agreement

      such Indebtedness or the beneficiary or beneficiaries of such Guarantee
      (or a trustee or agent on behalf of such holder or holders or beneficiary
      or beneficiaries) to cause, with the giving of notice if required, such
      Indebtedness to be demanded or to become due or to be repurchased,

      repurchase, prepay, defease or redeem such Indebtedness to be made, prior

      under the Loan Documents); or (ii) there occurs under any Swap Contract an
      Early Termination Date (as defined in such Swap Contract) resulting from

      liquidator, rehabilitator or similar officer is appointed without the
      application or consent of such Person and the appointment continues
      undischarged or unstayed for 60 calendar days; or any proceeding under any

      or surety does not dispute coverage), or (ii) any one or more non-monetary
      final judgments that have, or could reasonably be expected to have,
      individually or in the aggregate, a Material Adverse Effect and, in either
      case, (A) enforcement proceedings are commenced by any creditor upon such

      and effect; or any Loan Party or any other Person contests in any manner
      the validity or enforceability of any Loan Document; or any Loan Party

      Document, or purports to revoke, terminate or rescind any Loan Document
      other than in accordance with its terms; or

            (k) Change of Control. There occurs any Change of Control with

may, with the consent of, the Required Lenders, take any or all of the following
actions:

      be terminated, whereupon such Revolving Commitment shall be terminated,
      and/or (ii) at the request of, or may, with the consent of the Required
      Lenders, declare the commitment of each Lender to make Loans and any
      obligation of the L/C Issuer to make L/C Credit Extensions to be
      terminated, whereupon such commitments and obligation shall be terminated;

            (b) declare the unpaid principal amount of all outstanding Loans,
      all interest accrued and unpaid thereon, and all other amounts owing or
      payable hereunder or under any other Loan Document to be immediately due

                                       77
<PAGE>

      demand, protest or other notice of any kind, all of which are hereby
      expressly waived by the Borrower;

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

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

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

      SECTION 8.03 APPLICATION OF FUNDS. After the exercise of remedies provided
for in Section 8.02 (or after the Loans have automatically become immediately
due and payable and the L/C Obligations and any Swap Obligations have
automatically been required to be Cash Collateralized as set forth in the
proviso to Section 8.02), any amounts received on account of the Obligations
shall be applied by the Administrative Agent in the following order:

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

      Second, to payment of that portion of the Obligations constituting fees,
indemnities and other amounts (other than principal and interest) payable to the
Lenders (including Attorney Costs and amounts payable under Article III),
ratably among them in proportion to the amounts described in this clause Second
payable to them;

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

      Fourth, to payment of that portion of the Obligations constituting unpaid
principal of the Loans and L/C Borrowings (and to the extent any such amounts
are proceeds of Collateral or payments under any Guaranty, Swap Obligations in
respect of Swap Contracts), ratably among the Lenders (and to the extent
proceeds of Collateral or payments under any Guaranty, to the Guarantied Parties
and the Secured Lenders, as defined in each Guaranty) in proportion to the
respective amounts described in this clause Fourth held by them;

      Fifth, to the Administrative Agent for the account of the L/C Issuer, to
Cash Collateralize that portion of L/C Obligations comprised of the aggregate
undrawn amount of Letters of Credit; and

                                       78
<PAGE>

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

Subject to Section 2.04(c), amounts used to Cash Collateralize the aggregate
undrawn amount of Letters of Credit pursuant to clause Fifth above shall be
applied to satisfy drawings under such Letters of Credit as they occur. If any
amount remains on deposit as Cash Collateral after all Letters of Credit have
either been fully drawn or expired, such remaining amount shall be applied to
the other Obligations, if any, in the order set forth above.

                                   ARTICLE IX.
                              ADMINISTRATIVE AGENT

      SECTION 9.01 APPOINTMENT AND AUTHORITY. Each of the Lenders and the L/C
Issuer hereby irrevocably appoints Wells Fargo to act on its behalf as the
Administrative Agent hereunder and under the other Loan Documents and authorizes
the Administrative Agent to take such actions on its behalf and to exercise such
powers as are delegated to the Administrative Agent by the terms hereof or
thereof, together with such actions and powers as are reasonably incidental
thereto. The provisions of this Article are solely for the benefit of the
Administrative Agent, the Lenders and the L/C Issuer, and neither the Borrower
nor any other Loan Party shall have rights as a third party beneficiary of any
of such provisions.

      SECTION 9.02 RIGHTS AS A LENDER. The Person serving as the Administrative
Agent hereunder shall have the same rights and powers in its capacity as a
Lender as any other Lender and may exercise the same as though it were not the
Administrative Agent and the term "Lender" or "Lenders" shall, unless otherwise
expressly indicated or unless the context otherwise requires, include the Person
serving as the Administrative Agent hereunder in its individual capacity. Such
Person and its Affiliates may accept deposits from, lend money to, act as the
financial advisor or in any other advisory capacity for and generally engage in
any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if such Person were not the Administrative Agent hereunder and
without any duty to account therefor to the Lenders.

      SECTION 9.03 EXCULPATORY PROVISIONS. The Administrative Agent shall not
have any duties or obligations except those expressly set forth herein and in
the other Loan Documents. Without limiting the generality of the foregoing, the
Administrative Agent:

            (a) shall not be subject to any fiduciary or other implied duties,
      regardless of whether a Default has occurred and is continuing;

            (b) shall not have any duty to take any discretionary action or
      exercise any discretionary powers, except discretionary rights and powers
      expressly contemplated hereby or by the other Loan Documents that the
      Administrative Agent is required to exercise as directed in writing by the
      Required Lenders (or such other number or percentage of the Lenders as
      shall be expressly provided for herein or in the other Loan Documents),
      provided that the Administrative Agent shall not be required to take any
      action that, in its opinion or the opinion of its counsel, may expose the
      Administrative Agent to liability or that is contrary to any Loan Document
      or applicable law; and

                                       79
<PAGE>

            (c) shall not, except as expressly set forth herein and in the other
      Loan Documents, have any duty to disclose, and shall not be liable for the
      failure to disclose, any information relating to the Borrower or any of
      its Affiliates that is communicated to or obtained by the Person serving
      as the Administrative Agent or any of its Affiliates in any capacity.

      The Administrative Agent shall not be liable for any action taken or not
taken by it (i) with the consent or at the request of the Required Lenders (or
such other number or percentage of the Lenders as shall be necessary, or as the
Administrative Agent shall believe in good faith shall be necessary, under the
circumstances as provided in Sections 10.01 and 8.02 or (ii) in the absence of
its own gross negligence or willful misconduct. The Administrative Agent shall
be deemed not to have knowledge of any Default unless and until notice
describing such Default is given to the Administrative Agent by the Borrower, a
Lender or the L/C Issuer.

      The Administrative Agent shall not be responsible for or have any duty to
ascertain or inquire into (i) any statement, warranty or representation made in
or in connection with this Agreement or any other Loan Document, (ii) the
contents of any certificate, report or other document delivered hereunder or
thereunder or in connection herewith or therewith, (iii) the performance or
observance of any of the covenants, agreements or other terms or conditions set
forth herein or therein or the occurrence of any Default, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan
Document or any other agreement, instrument or document or (v) the satisfaction
of any condition set forth in Article IV or elsewhere herein, other than to
confirm receipt of items expressly required to be delivered to the
Administrative Agent.

      SECTION 9.04 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent
shall be entitled to rely upon, and shall not incur any liability for relying
upon, any notice, request, certificate, consent, statement, instrument, document
or other writing (including any electronic message, Internet or intranet website
posting or other distribution) believed by it to be genuine and to have been
signed, sent or otherwise authenticated by the proper Person. The Administrative
Agent also may rely upon any statement made to it orally or by telephone and
believed by it to have been made by the proper Person, and shall not incur any
liability for relying thereon. In determining compliance with any condition
hereunder to the making of a Loan, or the issuance of a Letter of Credit, that
by its terms must be fulfilled to the satisfaction of a Lender or the L/C
Issuer, the Administrative Agent may presume that such condition is satisfactory
to such Lender or the L/C Issuer unless the Administrative Agent shall have
received notice to the contrary from such Lender or the L/C Issuer prior to the
making of such Loan or the issuance of such Letter of Credit. The Administrative
Agent may consult with legal counsel (who may be counsel for the Borrower),
independent accountants and other experts selected by it, and shall not be
liable for any action taken or not taken by it in accordance with the advice of
any such counsel, accountants or experts.

      SECTION 9.05 DELEGATION OF DUTIES. The Administrative Agent may perform
any and all of its duties and exercise its rights and powers hereunder or under
any other Loan Document by or through any one or more sub-agents appointed by
the Administrative Agent. The Administrative Agent and any such sub-agent may
perform any and all of its duties and exercise its rights and powers by or
through their respective Related Parties. The exculpatory provisions

                                       80
<PAGE>

of this Article shall apply to any such sub-agent and to the Related Parties of
the Administrative Agent and any such sub-agent, and shall apply to their
respective activities in connection with the syndication of the credit
facilities provided for herein as well as activities as Administrative Agent.

      SECTION 9.06 RESIGNATION OF ADMINISTRATIVE AGENT. The Administrative Agent
may at any time give notice of its resignation to the Lenders, the L/C Issuer
and the Borrower. Upon receipt of any such notice of resignation, the Required
Lenders shall have the right, in consultation with the Borrower, to appoint a
successor, which shall be a bank with an office in the United States, or an
Affiliate of any such bank with an office in the United States. If no such
successor shall have been so appointed by the Required Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative Agent
gives notice of its resignation, then the retiring Administrative Agent may on
behalf of the Lenders and the L/C Issuer, appoint a successor Administrative
Agent meeting the qualifications set forth above; provided that if the
Administrative Agent shall notify the Borrower and the Lenders that no
qualifying Person has accepted such appointment, then such resignation shall
nonetheless become effective in accordance with such notice and (1) the retiring
Administrative Agent shall be discharged from its duties and obligations
hereunder and under the other Loan Documents and (2) all payments,
communications and determinations provided to be made by, to or through the
Administrative Agent shall instead be made by or to each Lender and the L/C
Issuer directly, until such time as the Required Lenders appoint a successor
Administrative Agent as provided for above in this Section. Upon the acceptance
of a successor's appointment as Administrative Agent hereunder, such successor
shall succeed to and become vested with all of the rights, powers, privileges
and duties of the retiring (or retired) Administrative Agent, and the retiring
Administrative Agent shall be discharged from all of its duties and obligations
hereunder or under the other Loan Documents (if not already discharged therefrom
as provided above in this Section). The fees payable by the Borrower to a
successor Administrative Agent shall be the same as those payable to its
predecessor unless otherwise agreed between the Borrower and such successor.
After the retiring Administrative Agent's resignation hereunder and under the
other Loan Documents, the provisions of this Article and Section 10.04 shall
continue in effect for the benefit of such retiring Administrative Agent, its
sub-agents and their respective Related Parties in respect of any actions taken
or omitted to be taken by any of them while the retiring Administrative Agent
was acting as Administrative Agent.

      Any resignation by Wells Fargo as Administrative Agent pursuant to this
Section shall also constitute its resignation as L/C Issuer and Swing Line
Lender. Upon the acceptance of a successor's appointment as Administrative Agent
hereunder, (a) such successor shall succeed to and become vested with all of the
rights, powers, privileges and duties of the retiring L/C Issuer and Swing Line
Lender, (b) the retiring L/C Issuer and Swing Line Lender shall be discharged
from all of their respective duties and obligations hereunder or under the other
Loan Documents, and (c) the successor L/C Issuer shall issue letters of credit
in substitution for the Letters of Credit, if any, outstanding at the time of
such succession or make other arrangement satisfactory to the retiring L/C
Issuer to effectively assume the obligations of the retiring L/C Issuer with
respect to such Letters of Credit.

      SECTION 9.07 NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS. Each
Lender and the L/C Issuer acknowledges that it has, independently and without
reliance upon the

                                       81
<PAGE>

Administrative Agent or any other Lender or any of their Related Parties and
based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender and
the L/C Issuer also acknowledges that it will, independently and without
reliance upon the Administrative Agent or any other Lender or any of their
Related Parties and based on such documents and information as it shall from
time to time deem appropriate, continue to make its own decisions in taking or
not taking action under or based upon this Agreement, any other Loan Document or
any related agreement or any document furnished hereunder or thereunder.

      SECTION 9.08 NO OTHER DUTIES, ETC. Anything herein to the contrary
notwithstanding, none of any Arrangers listed on the cover page hereof shall
have any powers, duties or responsibilities under this Agreement or any of the
other Loan Documents, except in its capacity, as applicable, as the
Administrative Agent, a Lender or the L/C Issuer hereunder.

      SECTION 9.09 ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to any Loan Party, the Administrative Agent (irrespective of
whether the principal of any Loan or L/C Obligation shall then be due and
payable as herein expressed or by declaration or otherwise and irrespective of
whether the Administrative Agent shall have made any demand on the Borrower)
shall be entitled and empowered, by intervention in such proceeding or otherwise

            (a) to file and prove a claim for the whole amount of the principal
      and interest owing and unpaid in respect of the Loans, L/C Obligations and
      all other Obligations that are owing and unpaid and to file such other
      documents as may be necessary or advisable in order to have the claims of
      the Lenders, the L/C Issuer and the Administrative Agent (including any
      claim for the reasonable compensation, expenses, disbursements and
      advances of the Lenders, the L/C Issuer and the Administrative Agent and
      their respective agents and counsel and all other amounts due the Lenders,
      the L/C Issuer and the Administrative Agent under Sections 2.04(h) and
      (i), 2.10 and 10.04) allowed in such judicial proceeding; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to the Administrative Agent and, in the event
that the Administrative Agent shall consent to the making of such payments
directly to the Lenders, to pay to the Administrative Agent any amount due for
the reasonable compensation, expenses, disbursements and advances of the
Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Sections 2.10 and 10.04.

      Nothing contained herein shall be deemed to authorize the Administrative
Agent to authorize or consent to or accept or adopt on behalf of any Lender any
plan of reorganization, arrangement, adjustment or composition affecting the
Obligations or the rights of any Lender or

                                       82
<PAGE>

to authorize the Administrative Agent to vote in respect of the claim of any
Lender in any such proceeding.

      SECTION 9.10 COLLATERAL AND GUARANTY MATTERS. The Lenders irrevocably
authorize the Administrative Agent,

            (a) to release any Lien on any property granted to or held by the
      Administrative Agent under any Loan Document (i) upon termination of the
      Aggregate Commitments and payment in full of all Obligations (other than
      contingent indemnification obligations) and the expiration or termination
      of all Letters of Credit, (ii) that is sold or to be sold as part of or in
      connection with any sale permitted hereunder or under any other Loan
      Document, or (iii) subject to Section 10.01, if approved, authorized or
      ratified in writing by the Required Lenders;

            (b) to subordinate any Lien on any property granted to or held by
      the Administrative Agent under any Loan Document to (i) any Lien on such
      property that is permitted by Section 7.01(i), and (ii) any lease or
      transfer on such property that is permitted by Section 7.01(l); and

            (c) to release on behalf of the Administrative Agent and the Lenders
      any Guarantor from its obligations under the Guaranty and under the other
      Loan Documents (i) upon termination of the Aggregate Commitments and
      payment in full of all Obligations (other than contingent indemnification
      obligations) and the expiration or termination of all Letters of Credit,
      (ii) if such Person ceases to be a Subsidiary as a result of a transaction
      permitted hereunder or (iii) subject to Section 10.01, if approved,
      authorized or ratified in writing, by the Lenders required for such
      action.

      Upon request by the Administrative Agent at any time, the Required Lenders
will confirm in writing the Administrative Agent's authority to release or
subordinate its interest in particular types or items of property, or to release
any Guarantor from its obligations under the Guaranty pursuant to this Section
9.10.

                                   ARTICLE X.
                                  MISCELLANEOUS

      SECTION 10.01 AMENDMENTS, ETC. No amendment or waiver of any provision of
this Agreement or any other Loan Document, and no consent to any departure by
the Borrower or any other Loan Party therefrom, shall be effective unless in
writing signed by the Required Lenders and the Borrower or the applicable Loan
Party, as the case may be, and acknowledged by the Administrative Agent, and
each such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which given; provided, however, that no such
amendment, waiver or consent shall:

            (a) waive any condition set forth in Section 4.01(a) without the
      written consent of each Lender;

                                       83

      Document for any payment (excluding mandatory prepayments) of principal,
      interest, fees or other amounts due to the Lenders (or any of them)
      hereunder or under any other Loan Document without the written consent of
      each Lender directly affected thereby;

            (d) reduce the principal of, or the rate of interest specified
      herein on, any Loan or L/C Borrowing, or (subject to clause (iv) of the
      second proviso to this Section 10.01) any fees or other amounts payable
      hereunder or under any other Loan Document without the written consent of
      each Lender directly affected thereby; provided, however, that only the
      consent of the Required Lenders shall be necessary (i) to amend the
      definition of "Default Rate" or to waive any obligation of the Borrower to
      pay interest at the Default Rate or (ii) to amend the Leverage Ratio (or
      any defined term used therein) even if the effect of such amendment would
      be to reduce the rate of interest on any Loan or L/C Borrowing or to
      reduce any fee payable hereunder;

            (e) change Section 2.14 or Section 8.03 in a manner that would alter

      CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE,
      CONTRIBUTORY OR SOLE NEGLIGENCE OF THE INDEMNITEE; PROVIDED THAT SUCH
      INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT THAT
      SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES (X) ARE

                                       87
<PAGE>

      DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE
      JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT
      OF SUCH INDEMNITEE OR (Y) RESULT FROM A CLAIM BROUGHT BY THE BORROWER OR

      (a) or (b) of this Section to be paid by it to the Administrative Agent
      (or any sub-agent thereof), the L/C Issuer or any Related Party of any of
      the foregoing, each Lender severally agrees to pay to the Administrative
      Agent (or any such sub-agent), the L/C Issuer or such Related Party, as
      the case may be, such Lender's Applicable Percentage (determined as of the
      time that the applicable unreimbursed expense or indemnity payment is
      sought) of such unpaid amount, provided that the unreimbursed expense or
      indemnified loss, claim, damage, liability or related expense, as the case
      may be, was incurred by or asserted against the Administrative Agent (or
      any such sub-agent) or the L/C Issuer in its capacity as such, or against
      any Related Party of any of the foregoing acting for the Administrative
      Agent (or any such sub-agent) or L/C Issuer in connection with such
      capacity. The obligations of the Lenders under this subsection (c) are
      subject to the provisions of Section 2.12(d).

      permitted by applicable law, the Borrower shall not assert, and hereby
      waives, any claim against any Indemnitee, on any theory of liability, for

      or actual damages) arising out of, in connection with, or as a result of,
      this Agreement, any other Loan Document or any agreement or instrument
      contemplated hereby, the transactions contemplated hereby or thereby, any
      Loan or Letter of Credit or the use of the proceeds thereof. No Indemnitee
      referred to in subsection (b) above shall (in the absence of bad faith,
      gross negligence or willful misconduct) be liable for any damages arising
      from the use by unintended recipients of any information or other
      materials distributed by it through telecommunications, electronic or
      other information transmission systems in connection with this Agreement
      or the other Loan Documents or the transactions contemplated hereby or
      thereby.

            (e) Payments. All amounts due under this Section shall be payable
      not later than ten Business Days after demand therefor.

            (f) Survival. The agreements in this Section shall survive the
      resignation of the Administrative Agent and the L/C Issuer, the
      replacement of any Lender, the termination of the Aggregate Commitments
      and the repayment, satisfaction or discharge of all the other Obligations.

                                       88

      SECTION 10.05 PAYMENTS SET ASIDE. To the extent that any payment by or on
behalf of the Borrower is made to the Administrative Agent, the L/C Issuer or
any Lender, or the Administrative Agent, the L/C Issuer or any Lender exercises
its right of setoff, and such payment or the proceeds of such setoff 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, the L/C Issuer 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 setoff had not occurred, and (b) each Lender
and the L/C Issuer severally agrees to pay to the Administrative Agent upon
demand its applicable share (without duplication) of any amount so recovered
from or repaid by the Administrative Agent, plus interest thereon from the date
of such demand to the date such payment is made at a rate per annum equal to the
Federal Funds Rate from time to time in effect. The obligations of the Lenders
and the L/C Issuer under clause (b) of the preceding sentence shall survive the
payment in full of the Obligations and the termination of this Agreement.

      SECTION 10.06 SUCCESSORS AND ASSIGNS.

            (a) Successors and Assigns Generally. 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 the
      Administrative Agent and each Lender and no Lender may assign or otherwise
      transfer any of its rights or obligations hereunder except (i) to an
      Eligible Assignee in accordance with the provisions of subsection (b) of
      this Section, (ii) by way of participation in accordance with the
      provisions of subsection (d) of this Section, or (iii) by way of pledge or
      assignment of a security interest subject to the restrictions of
      subsection (f) of this Section (and any other attempted assignment or
      transfer by any party hereto shall be null and void). Nothing in this
      Agreement, expressed or implied, shall be construed to confer upon any
      Person (other than the parties hereto, their respective successors and
      assigns permitted hereby, Participants to the extent provided in
      subsection (d) of this Section and, to the extent expressly contemplated
      hereby, the Related Parties of each of the Administrative Agent, the L/C
      Issuer and the Lenders) any legal or equitable right, remedy or claim
      under or by reason of this Agreement.

            (b) Assignments by Lenders. Any Lender may at any time assign to one
      or more Eligible Assignees all or a portion of its rights and obligations
      under this Agreement (including all or a portion of its Commitment and the
      Loans (including for purposes of this subsection (b), participations in
      L/C Obligations and in Swing Line Loans) at the time owing to it);
      provided that

                  (i) except in the case of an assignment of the entire
            remaining amount of the assigning Lender's Commitment and the Loans
            at the time owing to it or in the case of an assignment to a Lender
            or an Affiliate of a Lender or an Approved Fund with respect to a
            Lender, the aggregate amount of the Commitment (which for this
            purpose includes Loans outstanding thereunder) or, if the Commitment
            is

                                       89
<PAGE>

            not then in effect, the principal outstanding balance of the Loans
            of the assigning Lender subject to each such assignment, determined
            as of the date the Assignment and Assumption with respect to such
            assignment is delivered to the Administrative Agent or, if "Trade
            Date" is specified in the Assignment and Assumption, as of the Trade
            Date, shall not be less than $5,000,000 unless each of the
            Administrative Agent and, so long as no Event of Default has
            occurred and is continuing, the Borrower otherwise consents (each
            such consent not to be unreasonably withheld or delayed);

                  (ii) each partial assignment shall be made as an assignment of
            a proportionate part of all the assigning Lender's rights and
            obligations under this Agreement with respect to its Revolving
            Commitment and its portion of the Term Loan, except that this clause
            (ii) shall not apply to rights in respect of Swing Line Loans;

                  (iii) any assignment of a Commitment must be approved by the
            Administrative Agent, the L/C Issuer and the Swing Line Lender
            unless the Person that is the proposed assignee is itself a Lender
            (whether or not the proposed assignee would otherwise qualify as an
            Eligible Assignee); and

                  (iv) the parties to each assignment shall execute and deliver
            to the Administrative Agent an Assignment and Assumption, together
            with a processing and recordation fee of $3,500 (which fee shall not
            be reimbursable by any Loan Party), and the Eligible Assignee, if it
            shall not be a Lender, shall deliver to the Administrative Agent an
            Administrative Questionnaire.

Subject to acceptance and recording thereof by the Administrative Agent pursuant
to subsection (c) of this Section, from and after the effective date specified
in each Assignment and Assumption, the Eligible Assignee thereunder shall be a
party to this Agreement and, to the extent of the interest assigned by such
Assignment and Assumption, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04 with
respect to facts and circumstances occurring prior to the effective date of such
assignment). Upon request, the Borrower (at its expense) shall execute and
deliver a Note to the assignee Lender. Any assignment or transfer by a Lender of
rights or obligations under this Agreement that does not comply with this
subsection shall be treated for purposes of this Agreement as a sale by such
Lender of a participation in such rights and obligations in accordance with
subsection (d) of this Section.

            (c) Register. The Administrative Agent, acting solely for this
      purpose as an agent of the Borrower, shall maintain at the Administrative
      Agent's Office a copy of each Assignment and Assumption delivered to it
      and a register for the recordation of the names and addresses of the
      Lenders, and the Commitments of, and principal amounts of the Loans and
      L/C Obligations owing to, each Lender pursuant to the terms hereof from

                                       90
<PAGE>

      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 each of the Borrower and the L/C Issuer at any
      reasonable time and from time to time upon reasonable prior notice. In
      addition, at any time that a request for a consent for a material or
      substantive change to the Loan Documents is pending, any Lender wishing to
      consult with other Lenders in connection therewith may request and receive
      from the Administrative Agent a copy of the Register.

            (d) Participations. Any Lender may at any time, without the consent
      of, or notice to, the Borrower or the Administrative Agent, sell
      participations to any Person (other than a natural person or the Borrower
      or any of the Borrower's Affiliates or Subsidiaries) (each, a
      "Participant") in all or a portion of such Lender's rights and/or
      obligations under this Agreement (including all or a portion of its
      Commitment and/or the Loans (including such Lender's participations in L/C
      Obligations and/or Swing Line Loans) owing to it); provided that (i) such
      Lender's obligations under this Agreement shall remain unchanged, (ii)
      such Lender shall remain solely responsible to the other parties hereto
      for the performance of such obligations and (iii) the Borrower, the
      Administrative Agent, the Lenders and the L/C Issuer shall continue to
      deal solely and directly with such Lender in connection with such Lender's
      rights and obligations under this Agreement.

      Any agreement or instrument pursuant to which a Lender sells such a
participation shall provide that such Lender shall retain the sole right to
enforce this Agreement and to approve any amendment, modification or waiver of
any provision of this Agreement; provided that such agreement or instrument may
provide that such Lender will not, without the consent of the Participant, agree
to any amendment, waiver or other modification described in the first proviso to
Section 10.01 that directly affects such Participant. Subject to subsection (e)
of this Section, the Borrower agrees that each Participant shall be entitled to
the benefits of Sections 3.01, 3.04 and 3.05 to the same extent as if it were a
Lender and had acquired its interest by assignment pursuant to subsection (b) of
this Section. To the extent permitted by law, each Participant also shall be
entitled to the benefits of Section 10.08 as though it were a Lender, provided
such Participant agrees to be subject to Section 2.14 as though it were a
Lender.

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

            (f) Certain Pledges. 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 Note, if any) to secure obligations of such Lender,
      including any pledge or assignment to secure

                                       91
<PAGE>

      obligations to a Federal Reserve Bank; provided that no such pledge or
      assignment shall release such Lender from any of its obligations hereunder
      or substitute any such pledgee or assignee for such Lender as a party
      hereto.

            (g) Electronic Execution of Assignments. The words "execution,"
      "signed," "signature," and words of like import in any Assignment and
      Assumption shall be deemed to include electronic signatures or the keeping
      of records in electronic form, each of which shall be of the same legal
      effect, validity or enforceability as a manually executed signature or the
      use of a paper-based recordkeeping system, as the case may be, to the
      extent and as provided for in any applicable law, including the Federal
      Electronic Signatures in Global and National Commerce Act, the New York
      State Electronic Signatures and Records Act, or any other similar state
      laws based on the Uniform Electronic Transactions Act.

            (h) Resignation as L/C Issuer or Swing Line Lender after Assignment.
      Notwithstanding anything to the contrary contained herein, if at any time
      Wells Fargo assigns all of its Commitment and Loans pursuant to subsection
      (b) above, Wells Fargo may, (i) upon 30 days' notice to the Borrower and
      the Lenders, resign as L/C Issuer and/or (ii) upon 30 days' notice to the
      Borrower, resign as Swing Line Lender. In the event of any such
      resignation as L/C Issuer or Swing Line Lender, the Borrower shall be
      entitled to appoint from among the Lenders a successor L/C Issuer or Swing
      Line Lender hereunder; provided, however, that no failure by the Borrower
      to appoint any such successor shall affect the resignation of Wells Fargo
      as L/C Issuer or Swing Line Lender, as the case may be. If Wells Fargo
      resigns as L/C Issuer, it shall retain all the rights and obligations of
      the L/C Issuer hereunder with respect to all Letters of Credit outstanding
      as of the effective date of its resignation as L/C Issuer and all L/C
      Obligations with respect thereto (including the right to require the
      Lenders to make Base Rate Loans or fund risk participations in
      Unreimbursed Amounts pursuant to Section 2.04(c)). If Wells Fargo resigns
      as Swing Line Lender, it shall retain all the rights of the Swing Line
      Lender provided for hereunder with respect to Swing Line Loans made by it
      and outstanding as of the effective date of such resignation, including
      the right to require the Lenders to make Base Rate Loans or fund risk
      participations in outstanding Swing Line Loans pursuant to Section
      2.05(c).

      SECTION 10.07 TREATMENT OF CERTAIN INFORMATION; CONFIDENTIALITY. Each of
the Administrative Agent, the Lenders and the L/C Issuer agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its Affiliates' and to its Affiliates' respective
partners, directors, officers, employees, agents, advisors and representatives
(it being understood that the Persons to whom such disclosure is made will be
informed of the confidential nature of such Information and instructed to keep
such Information confidential), (b) to the extent requested by any regulatory
authority purporting to have jurisdiction over it (including any self-regulatory
authority, such as the National Association of Insurance Commissioners), (c) to
the extent required by applicable laws or regulations or by any subpoena or
similar legal process, (d) to any other party hereto, (e) in connection with the
exercise of any remedies hereunder or under any other Loan Document or any
action or proceeding relating to this Agreement or any other Loan Document or
the enforcement of rights hereunder or thereunder, (f) subject to an agreement
containing provisions substantially the same

                                       92
<PAGE>

as those of this Section, to (i) any assignee of or Participant in, or any
prospective assignee of or Participant in, any of its rights or obligations
under this Agreement or (ii) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to the Borrower and its
obligations, (g) with the consent of the Borrower or (h) to the extent such
Information (x) becomes publicly available other than as a result of a breach of
this Section or (y) becomes available to the Administrative Agent, any Lender,
the L/C Issuer or any of their respective Affiliates on a nonconfidential basis
from a source other than the Borrower.

      For purposes of this Section, "Information" means all information received
from the Borrower or any Subsidiary relating to the Borrower or any Subsidiary
or any of their respective businesses, other than any such information that is
available to the Administrative Agent, any Lender or the L/C Issuer on a
nonconfidential basis prior to disclosure by the Borrower or any Subsidiary,
provided that, in the case of information received from the Borrower or any
Subsidiary after the date hereof, such information is clearly identified 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 10.08 SET-OFF. If an Event of Default shall have occurred and be
continuing, each Lender, the L/C Issuer and each of their respective Affiliates
is hereby authorized at any time and from time to time, to the fullest extent
permitted by applicable law, to set off and apply any and all deposits (general
or special, time or demand, provisional or final, in whatever currency) at any
time held and other obligations (in whatever currency) at any time owing by such
Lender, the L/C Issuer or any such Affiliate to or for the credit or the account
of the Borrower or any other Loan Party against any and all of the obligations
of the Borrower or such Loan Party now or hereafter existing under this
Agreement or any other Loan Document to such Lender or the L/C Issuer,
irrespective of whether or not such Lender or the L/C Issuer shall have made any
demand under this Agreement or any other Loan Document and although such
obligations of the Borrower or such Loan Party may be contingent or unmatured or
are owed to a branch or office of such Lender or the L/C Issuer different from
the branch or office holding such deposit or obligated on such indebtedness. The
rights of each Lender, the L/C Issuer and their respective Affiliates under this
Section are in addition to other rights and remedies (including other rights of
setoff) that such Lender, the L/C Issuer or their respective Affiliates may
have. Each Lender and the L/C Issuer agrees to notify the Borrower and the
Administrative Agent promptly after any such setoff and application, provided
that the failure to give such notice shall not affect the validity of such
setoff and application.

      SECTION 10.09 INTEREST RATE LIMITATION. Notwithstanding anything to the
contrary contained in any Loan Document, the interest paid or agreed to be paid
under the Loan Documents shall not exceed the Highest Lawful Rate. If the
Administrative Agent or any Lender shall receive interest in an amount that
exceeds the Highest Lawful Rate, the excess interest shall be applied to the
principal of the Loans or, if it exceeds such unpaid principal, refunded to the
Borrower. In determining whether the interest contracted for, charged, or
received by the Administrative Agent or a Lender exceeds the Highest Lawful
Rate, such Person may, to the extent permitted by Applicable Law, (a)
characterize any payment that is not principal as an expense, fee, or premium
rather than interest, (b) exclude voluntary prepayments and the effects

                                       93
<PAGE>

thereof, and (c) amortize, prorate, allocate, and spread in equal or unequal
parts the total amount of interest throughout the contemplated term of the
Obligations hereunder.

      SECTION 10.10 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement may
be executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and the other
Loan Documents constitute the entire contract among the parties relating to the
subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by the Administrative Agent and when the Administrative Agent
shall have received counterparts hereof that, when taken together, bear the
signatures of each of the other parties hereto. Delivery of an executed
counterpart of a signature page of this Agreement by telecopy shall be effective
as delivery of a manually executed counterpart of this Agreement.

      SECTION 10.11 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 at the time of any Credit Extension, and shall continue in full
force and effect as long as any Loan or any other Obligation hereunder shall
remain unpaid or unsatisfied or any Letter of Credit shall remain outstanding.

      SECTION 10.12 SEVERABILITY. If any provision of this Agreement or the
other Loan Documents is held to be illegal, invalid or unenforceable, (a) the
legality, validity and enforceability of the remaining provisions of this
Agreement and the other Loan Documents shall not be affected or impaired thereby
and (b) the parties shall endeavor in good faith negotiations to replace the
illegal, invalid or unenforceable provisions with valid provisions the economic
effect of which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      SECTION 10.13 REPLACEMENT OF LENDERS. If any Lender requests compensation
under Section 3.04, or if the Borrower is required to pay any additional amount
to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 3.01, if any Lender gives notice under Section 3.02 which
remains in effect, if any Lender is a Defaulting Lender or if any other
circumstance exists hereunder that gives the Borrower the right to replace a
Lender as a party hereto in connection with any proposed amendment,
modification, termination, waiver or consent with respect to any of the
provisions hereof as contemplated by Section 10.01, the consent of Required
Lenders shall have been obtained but the consent of one or more of such other
Lenders whose consent is required shall not have been obtained, then the
Borrower may, at its sole expense and effort, upon notice to such Lender and the
Administrative Agent, require such Lender to assign and delegate, without
recourse (in accordance with and subject to the restrictions contained in, and
consents required by, Section 10.06), all of its interests, rights and

                                       94
<PAGE>

obligations under this Agreement and the related Loan Documents to an assignee
that shall assume such obligations (which assignee may be another Lender, if a
Lender accepts such assignment), provided that:

            (a) the Borrower shall have paid to the Administrative Agent the
      assignment fee specified in Section 10.06(b);

            (b) such Lender shall have received payment of an amount equal to
      the outstanding principal of its Loans and L/C Advances, accrued interest
      thereon, accrued fees and all other amounts payable to it hereunder and
      under the other Loan Documents (including any amounts under Section 3.05)
      from the assignee (to the extent of such outstanding principal and accrued
      interest and fees) or the Borrower (in the case of all other amounts);

            (c) in the case of any such assignment resulting from a claim for
      compensation under Section 3.04 or payments required to be made pursuant
      to Section 3.01, such assignment will result in a reduction in such
      compensation or payments thereafter; and

            (d) such assignment does not conflict with applicable Laws.

      SECTION 10.14 GOVERNING LAW.

            (a) THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
      WITH, the LAW OF THE STATE OF TEXAS applicable to agreements made and to
      be performed entirely within such State; PROVIDED THAT THE ADMINISTRATIVE
      Agent AND EACH LENDER SHALL RETAIN ALL RIGHTS ARISING UNDER FEDERAL LAW.

            (b) THE BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY AND

      AND OF THE UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF TEXAS

      AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE
      CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE
      JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS AGREEMENT
      OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE

                                       95
<PAGE>

      ADMINISTRATIVE AGENT, ANY LENDER OR THE L/C ISSUER MAY OTHERWISE HAVE TO
      BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR ANY OTHER
      LOAN DOCUMENT AGAINST THE BORROWER OR ANY OTHER LOAN PARTY OR ITS
      PROPERTIES IN THE COURTS OF ANY JURISDICTION.

            (c) THE BORROWER AND EACH OTHER LOAN PARTY IRREVOCABLY AND
      UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW,

      FULLEST EXTENT PERMITTED BY APPLICABLE LAW, THE DEFENSE OF AN INCONVENIENT
      FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH COURT.

      346.004) of the Texas Finance Code (which regulates certain revolving
      credit accounts and revolving tri-party accounts) shall not apply to the
      Loans or the other Obligations.

            (e) 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 TEXAS
      SITTING IN DALLAS COUNTY, TEXAS OR OF THE UNITED STATES DISTRICT COURT FOR
      THE NORTHERN DISTRICT OF TEXAS (DALLAS DIVISION), 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

      FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING

      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 10.15 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

                                       96
<PAGE>

FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND
CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED
BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN
ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN
EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT
TO TRIAL BY JURY.

      SECTION 10.16 USA PATRIOT ACT NOTICE. Each Lender that is subject to the
Act (as hereinafter defined) and the Administrative Agent (for itself and not on
behalf of any Lender) hereby notifies the Borrower that pursuant to the
requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into
law October 26, 2001)) (the "Act"), it is required to obtain, verify and record
information that identifies the Borrower, which information includes the name
and address of the Borrower and other information that will allow such Lender or
the Administrative Agent, as applicable, to identify the Borrower in accordance
with the Act.

      SECTION 10.17 ARBITRATION.

            (a) Arbitration. Upon the demand of any party, any Dispute shall be
      resolved by binding arbitration in accordance with the terms of this
      Agreement. A "Dispute" shall mean any action, dispute, claim or
      controversy of any kind, whether in contract or tort, statutory or common
      law, legal or equitable, now existing or hereafter arising under or in
      connection with, or in any way pertaining to, this Agreement, or any past,
      present or future extensions of credit and other activities, transactions
      or obligations of any kind related directly or indirectly to this
      Agreement, including without limitation, any of the foregoing arising in
      connection with the exercise of any self-help, ancillary or other remedies
      pursuant to this Agreement. Any party may by summary proceedings bring an
      action in court to compel arbitration of a Dispute. Any party who fails or
      refuses to submit to arbitration following a lawful demand by any other
      party shall bear all costs and expenses incurred by such other party in
      compelling arbitration of any Dispute.

            (b) Governing Rules. Arbitration proceedings shall be administered
      by the American Arbitration Association ("AAA") or such other
      administrator as the parties shall mutually agree upon in accordance with
      the AAA Commercial Arbitration Rules. All Disputes submitted to
      arbitration shall be resolved in accordance with the Federal Arbitration
      Act (Title 9 of the United States Code), notwithstanding any conflicting
      choice of law provision in this Agreement. The arbitration shall be
      conducted at a location in Dallas, Texas selected by the AAA or other
      administrator. If there is any inconsistency between the terms hereof and
      any such rules, the terms and procedures set forth herein shall control.
      All statutes of limitation applicable to any Dispute shall apply to any
      arbitration proceeding. All discovery activities shall be expressly
      limited to matters directly relevant to the Dispute being arbitrated.
      Judgment upon any award rendered in an arbitration may be entered in any
      court having jurisdiction; provided however, that nothing contained herein
      shall be deemed to be a waiver by any party that is a bank of the
      protections afforded to it under 12 U.S.C. Section 91 or any similar
      applicable state law.

                                       97
<PAGE>

            (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No
      provision hereof shall limit the right of any party to exercise self-help
      remedies such as setoff, foreclosure against or sale of any real or
      personal property collateral or security, or to obtain provisional or
      ancillary remedies, including without limitation injunctive relief,
      sequestration, attachment, garnishment or the appointment of a receiver,
      from a court of competent jurisdiction before, after or during the
      pendency of any arbitration or other proceeding. The exercise of any such
      remedy shall not waive the right of any party to compel arbitration
      hereunder.

            (d) Arbitrator Qualifications and Powers Awards. Arbitrators must be
      active members of the State Bar of Texas with expertise in the substantive
      laws applicable to the subject matter of the Dispute. Arbitrators are
      empowered to resolve Disputes by summary rulings in response to motions
      filed prior to the final arbitration hearing. Arbitrators (i) shall
      resolve all Disputes in accordance with the substantive law of the state
      of Texas, (ii) may grant any remedy or relief that a court of the state of
      Texas could order or grant within the scope hereof and such ancillary
      relief as is necessary to make effective any award, and (iii) shall have
      the power to award recovery of all costs and fees, to impose sanctions and
      to take such other actions as they deem necessary to the same extent a
      judge could pursuant to the Federal Rules of Civil Procedure, the Texas
      Rules of Civil Procedure or other applicable law. Any Dispute in which the
      amount in controversy is $5,000,000 or less shall be decided by a single
      arbitrator who shall not render an award of greater than $5,000,000
      (including damages, costs, fees and expenses). By submission to a single
      arbitrator, each party expressly waives any right or claim to recover more
      than $5,000,000. Any Dispute in which the amount in controversy exceeds
      $5,000,000 shall be decided by majority vote of a panel of three
      arbitrators; provided however, that all three arbitrators must actively
      participate in all hearings and deliberations.

            (e) Judicial Review. Notwithstanding anything herein to the
      contrary, in any arbitration in which the amount in controversy exceeds
      $25,000,000, the arbitrators shall be required to make specific, written
      findings of fact and conclusions of law. In such arbitrations (i) the
      arbitrators shall not have the power to make any award which is not
      supported by substantial evidence or which is based on legal error, (ii)
      an award shall not be binding upon the parties unless the findings of fact
      are supported by substantial evidence and the conclusions of law are not
      erroneous under the substantive law of the state of Texas, and (iii) the
      parties shall have in addition to the grounds referred to in the Federal
      Arbitration Act for vacating, modifying or correcting an award the right
      to judicial review of (A) whether the findings of fact rendered by the
      arbitrators are supported by substantial evidence, and (B) whether the
      conclusions of law are erroneous under the substantive law of the state of
      Texas. Judgment confirming an award in such a proceeding may be entered
      only if a court determines the award is supported by substantial evidence
      and not based on legal error under the substantive law of the state of
      Texas.

            (f) Miscellaneous. To the maximum extent practicable, the AAA, the
      arbitrators and the parties shall take all action required to conclude any
      arbitration proceedings within 180 days of the filing of the Dispute with
      the AAA. No arbitrator or

                                       98
<PAGE>

      other party to an arbitration proceeding may disclose the existence,
      content or results thereof, except for disclosures of information by a
      party required in the ordinary course of its business, by applicable law
      or regulations, or to the extent necessary to exercise any judicial review
      rights set forth herein. If more than one agreement for arbitration by or
      between the parties potentially applies to a Dispute, the arbitration
      provisions most directly related to this Agreement or the subject matter
      of the Dispute shall control. This arbitration provision shall survive
      termination, amendment or expiration of this Agreement or any relationship
      between the parties.

      SECTION 10.18 ENTIRE AGREEMENT. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG 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 AMONG THE
PARTIES.

                               SECURITY AGREEMENT

      SECURITY AGREEMENT (this "Agreement"), dated as of August 25, 2004, made
by each of the signatories party hereto (including any permitted successors and
assigns, collectively, the "Grantors" and each a "Grantor"), in favor of Wells
Fargo Bank, N.A., as Administrative Agent ("Administrative Agent"), for the
ratable benefit of the Lenders (as defined in the Credit Agreement defined
below) and Affiliates of the Lenders party to Swap Contracts with one or more of

Collateral except as perfected under Section 4.1) in favor of the Secured Party
for the Secured Creditors in the Collateral (subject to Liens otherwise
permitted by the Credit Agreement), securing the payment and performance of the
Obligations, and all filings and other actions necessary or desirable to perfect
and protect such security interest and such priority have been duly taken (or
will be taken upon each Grantor obtaining rights in Collateral after the date
hereof).

      (b) All of the Pledged Equity Interests have been duly and validly issued,
and the Pledged Stock is fully paid and nonassessable. All of the Pledged Equity
Interests consisting of certificated securities have been delivered to the
Administrative Agent. Other than Pledged Partnership Interests and Pledged LLC
Interests constituting General Intangibles, there are no Pledged Equity
Interests other than that represented by certificated securities in the
possession of the Administrative Agent. There are no restrictions in any
Organization Document governing any Pledged Equity Interest or any other
document related thereto which would limit or restrict (i) the grant of a Lien
in the Pledged Equity Interests, (ii) the perfection of such Lien or (iii) the
exercise of remedies in respect of such perfected Lien in the Pledged Equity
Interests as contemplated by this Agreement. Upon the exercise of remedies in
respect of Pledged Partnership Interests and Pledged LLC Interests, a transferee
or assignee of a partnership interests or membership interest, as the case may
be, of such partnership or limited liability company, as the case may be, shall
become a partner or member, as the case may be, of such partnership or limited
liability company, as the case may be, entitled to participate in the management
thereof and, upon the transfer of the entire interest of such Grantor, such
Grantor cases to be a partner or member, as the case may be.

      (c) Schedule 1, Section (a) states the jurisdiction of organization, type
of entity, entity identification number issued by the appropriate authority of
the jurisdiction of each Grantor's organization, and exact name of each Grantor,
as such name appears in its currently effective organizational documents as
filed with the appropriate authority of the jurisdiction of each

                                       10
<PAGE>

Grantor's organization. Schedule 1, Section (b) sets forth each other name each
Grantor has had in the past ten years, together with the date of the relevant
change. Except as set forth in Schedule 1, Section (c), each Grantor has not
changed its identity or type of entity in any way within the past ten years.
Changes in identity or type of entity include mergers, consolidations,
acquisitions (including both equity and asset acquisitions), and any change in
the form, nature, or jurisdiction of organization. Schedule 1 contains the
information required by this Section as to each acquiree or constituent party to
a merger, consolidation, or acquisition. Schedule 1, Section (d) states all
other names (including trade, assumed, and similar names) used by each Grantor
or any of its divisions or other business units at any time during the past ten
years. Schedule 1, Section (e) states the Federal Taxpayer Identification Number
of each Grantor.

      (d) The chief executive office of each Grantor is located at the address
stated on Schedule 2, Section (a). Schedule 2, Section (b) states all locations
where each Grantor maintains any books or records relating to all Accounts (with
each location at which Chattel Paper, if any, is kept being indicated by an
"*"). All Tangible Chattel Paper, promissory notes, and other Instruments
evidencing the Accounts have been delivered and pledged to Administrative Agent
duly endorsed and accompanied by such duly executed instruments of transfer or
assignment as are necessary for such pledge, to be held as pledged collateral.
Schedule 2, Section (c) states all locations where each Grantor maintains any
Equipment or Inventory. Schedule 2, Section (d) states all the places of
business of each Grantor or other locations of Collateral not identified in
Schedule 2, Sections 2 (a), (b), or (c). Schedule 2, Section (e) states the
names and addresses of all Persons other than each Grantor who have possession
of any of the Collateral or other property of each such Grantor.

      (e) All Accounts have been originated by each Grantor and all Inventory
has been acquired by each Grantor in the ordinary course of business. All
Inventory produced in the United States of America has been produced in
compliance with the Fair Labor Standards Act.

      (f) Schedule 3 is a complete and correct list of all the issued and
outstanding stock, partnership interests, limited liability company membership
interests, or other equity interest of each Grantor and the record and
beneficial owners of such stock, partnership interests, membership interests or
other equity interests. Also set forth on Schedule 3 is each equity investment
of each Grantor that represents 50% or less of the equity of the entity in which
such investment was made.

      (g) As of the Closing Date, each Grantor has no material Special
Collateral with a fair market value individually or in the aggregate in excess
of $500,000.

                                   ARTICLE IV

                                    COVENANTS

      4.1 Further Assurances.

      (a) Each Grantor will, from time to time and at each Grantor's expense,
promptly execute and deliver all further instruments and documents (including
the delivery of certificated securities and supplements to all schedules),
execute and file such financing or continuation

                                       11
<PAGE>

statements, or amendments thereto, and such other instruments or notices, as may
be reasonably necessary or desirable, or as Administrative Agent may request, in
order to perfect and preserve the pledge, assignment, and security interest
granted or purported to be granted hereby, and take all further action, that may
be reasonably necessary or desirable, or that Administrative Agent may
reasonably request, in order to perfect and protect any pledge, assignment, or
security interest granted or purported to be granted hereby, and the priority
thereof, or to enable Administrative Agent to exercise and enforce
Administrative Agent's and the Secured Creditors' rights and remedies hereunder
with respect to any Collateral; provided, however, no Grantor shall be required
to take any such actions in respect of any Special Collateral other than the
filing of financing statements or continuation statements, except as provided in
Section 4.1(e).

      (b) In addition to such other information as shall be specifically
provided for herein, each Grantor shall furnish to Administrative Agent such
other information with respect to the Collateral as Administrative Agent may
reasonably request.

      (c) Each Grantor authorizes Administrative Agent to file one or more
financing or continuation statements, and amendments thereto, relating to all or
any part of the Collateral without the authentication of any Grantor where
permitted by Law. A photocopy or other reproduction of this Agreement or any
financing statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by Law. Each Grantor
ratifies its execution and delivery of, and the filing of, any financing
statement describing any of the Collateral which was filed prior to the date of
this Agreement.

      (d) Each Grantor will not, and will not permit any Person to, revise,
modify, amend, or restate the articles of incorporation of any corporation the
stock or other interest in which is Pledged Stock or the partnership, joint
venture, or other organizational document of any partnership or joint venture
any interests in which are Pledged Partnership Interests or the articles of
organization or other organizational document of any limited liability company
any interests in which are Pledged LLC Interests in a manner that adversely
affects the security interest of the Secured Party therein except as permitted
by the Credit Agreement, or terminate, cancel, or dissolve any such Person
except as permitted by the Credit Agreement.

      (e) If Grantors or any or some of them shall acquire any Special
Collateral with a value greater than $500,000 individually or in the aggregate,
such Grantor shall notify Administrative Agent and, at Administrative Agent's
request, promptly execute and deliver all further instruments and documents as
may be reasonably necessary or desirable, or as Administrative Agent may
request, in order to grant, control, perfect and preserve a pledge, assignment,
and security interest in such assets and take all further action, that may be
reasonably necessary or desirable, or that Administrative Agent may reasonably
request, in order to grant, perfect and protect the pledge, assignment, or
security interest, and the priority thereof, or to enable Administrative Agent
to exercise and enforce Administrative Agent's and the Secured Creditors' rights
and remedies hereunder with respect to such Special Collateral so that the value
of such Special Collateral not subject to a perfected Lien does not exceed
$500,000 at any time during the term hereof.

      (f) To the extent information contained in any Schedules hereto may change
and such change would make the information contained in the Schedules materially
misleading, Grantors

                                       12
<PAGE>

shall, within 30 days of each such change, provide to Administrative Agent such
additional written corrective or supplemental information as may be necessary to
make such Schedules accurate and complete as of such date.

      4.2 Place of Perfection; Records; Collection of Accounts, Chattel Paper
and Instruments.

      (a) No Grantor shall change the jurisdiction of its organization from the
jurisdiction specified in Schedule 1, Section (a), its type of entity from the
type of entity specified in Schedule 1, Section (a), or its name from the name
specified in Schedule 1, Section (a) without providing notice thereof at least
10 days prior to the effective date of such change. Unless prior notice of any
change is given to Administrative Agent, each Grantor shall keep its chief
executive office at the address specified in Schedule 2, Section (a), and the
office where it keeps its material records concerning the Accounts, and the
originals of all material Chattel Paper and Instruments, at the address
specified in Schedule 2, Section (b). Each Grantor will hold and preserve such
records and Chattel Paper and Instruments and will permit representatives of
Administrative Agent at any time during normal business hours to inspect and
make abstracts from and copies of such records and Chattel Paper and
Instruments.

      (b) Except as otherwise provided in this Section 4.2(b), each Grantor
shall continue to collect, at its own expense, all amounts due or to become due
each Grantor under the Accounts, Chattel Paper, and Instruments. In connection
with such collections, each Grantor may take (and, at Administrative Agent's
direction, shall take) such action as each such Grantor or Administrative Agent
may deem necessary or advisable to enforce collection of the Accounts, Chattel
Paper, and Instruments; provided, however, that Administrative Agent shall have
the right, if an Event of Default exists and is continuing, without notice to
any Grantor, to notify the Account Debtors or obligors under any Accounts,
Chattel Paper, and Instruments of the assignment of such Accounts, Chattel
Paper, and Instruments to Administrative Agent and to direct such Account
Debtors or obligors to make payment of all amounts due or to become due to each
Grantor thereunder directly to Administrative Agent and, at the expense of each
Grantor, to enforce collection of any such Accounts, Chattel Paper, and
Instruments, and to adjust, settle or compromise the amount or payment thereof,
in the same manner and to the same extent as each Grantor might have done or as
Administrative Agent deems appropriate. If any Event of Default has occurred and
is continuing and upon notice to the Borrower and the applicable Grantor, all
amounts and proceeds (including Instruments) received by each Grantor in respect
of the Accounts, Chattel Paper, and Instruments shall be received in trust for
the benefit of Administrative Agent hereunder, shall be segregated from other
funds and property of each Grantor and shall be forthwith paid or delivered over
to Administrative Agent in the same form as so received (with any necessary
endorsement) to be held as cash collateral, thereafter to be applied as provided
in the Credit Agreement. Each Grantor shall not adjust, settle, or compromise
the amount or payment of any Account, Chattel Paper, or Instrument, release
wholly or partly any Account Debtor or obligor thereof, or allow any credit or
discount thereon, except in the ordinary course of business.

      4.3 Deposit Accounts. Each Grantor shall provide prior written notice that
it intends to establish or maintain any (a) Deposit Account or similar bank
account, and, upon written request of Administrative Agent, each Grantor shall
execute and deliver to Administrative Agent

                                       13
<PAGE>

assignments of such account in such form as Administrative Agent may reasonably
request, and cause the bank in which such account will be maintained, to deliver
to Administrative Agent acknowledgments of the assignment of such account in
form and substance satisfactory to Administrative Agent, and take all actions
necessary to establish in Administrative Agent control (as that term is defined
in the UCC) with respect to such Deposit Account. Upon reasonable written
request by Administrative Agent, each Grantor will take all actions necessary to
establish in Administrative Agent control (as that term is defined in the UCC)
with respect to each Deposit Account.

      4.4 Equipment, Fixtures, and Inventory.

      (a) Each Grantor shall keep its Equipment, Fixtures, and Inventory (other
than Inventory sold in the ordinary course of business) at such places in such
jurisdiction where all action required by Section 4.1 shall have been taken with
respect to the Equipment, Fixtures, and Inventory.

      (b) Each Grantor shall cause its Equipment and Fixtures to be maintained
and preserved in the same condition, repair, and working order as when new,
ordinary wear and tear excepted, and shall forthwith, or in the case of any loss
or damage to any of the Equipment and Fixtures as quickly as practicable after
the occurrence thereof, make or cause to be made all repairs, replacements, and
other improvements in connection therewith which are necessary or desirable to
such end except where the failure to do so could not reasonably be expected to
have a Material Adverse Effect.

      (c) Each Grantor shall comply in all material respects with, and shall
cause its licensees and subcontractors to comply in all material respects with,
all requirements of the Fair Labor Standards Act.

      4.5 Rights to Dividends and Distributions. With respect to any
certificates, bonds, or other Instruments or Securities constituting a part of
the Collateral, Administrative Agent shall have authority if an Event of Default
exists and is continuing, either to have the same registered in Administrative
Agent's name or in the name of a nominee, and, with or without such
registration, to demand of the issuer thereof, and to receive and receipt for,
any and all dividends (including any stock or similar dividend or distribution)
payable in respect thereof, whether they be ordinary or extraordinary. If any
Grantor shall become entitled to receive or shall receive any interest in or
certificate (including, without limitation, any interest in or certificate
representing a dividend or a distribution in connection with any
reclassification, increase, or reduction of capital, or issued in connection
with any reorganization), or any option or rights arising from or relating to
any of the Collateral, whether as an addition to, in substitution of, as a
conversion of, or in exchange for any of the Collateral, or otherwise, each
Grantor agrees to accept the same as Administrative Agent's agent and to hold
the same in trust on behalf of and for the benefit of Administrative Agent, and
to deliver the same immediately to Administrative Agent in the exact form
received, with appropriate undated stock or similar powers, duly executed in
blank, to be held by Administrative Agent, subject to the terms hereof, as
Collateral. Unless an Event of Default exists, each Grantor shall be entitled to
receive all cash dividends and distributions paid in respect of any of the
Collateral (subject to the restrictions of any other Loan Document).
Administrative Agent shall be entitled to all dividends and distributions, and
to any sums paid

                                       14
<PAGE>

upon or in respect of any Collateral, upon the liquidation, dissolution, or
reorganization of the issuer thereof which shall be paid to Administrative Agent
to be held by it as additional collateral security for and application to the
Obligations at the discretion of Administrative Agent. All dividends paid or
distributed in respect of the Collateral which are received by any Grantor in
violation of this Agreement shall, until paid or delivered to Administrative
Agent, be held by each Grantor in trust as additional Collateral for the
Obligations.

      4.6 Right of Administrative Agent to Notify Issuers. If an Event of
Default exists and is continuing and at such other times as Administrative Agent
is entitled to receive dividends and other property in respect of or consisting
of any Collateral which is or represents an equity or ownership interest in any
Person ("Securities Collateral"), Administrative Agent may notify issuers of the
Securities Collateral to make payments of all dividends and distributions
directly to Administrative Agent and Administrative Agent may take control of
all proceeds of any Securities Collateral. Until Administrative Agent elects to
exercise such rights, if an Event of Default exists, each Grantor, as agent of
Administrative Agent, shall collect and segregate all dividends and other
amounts paid or distributed with respect to the Securities Collateral.

      4.7 Insurance. Each Grantor shall, at its own expense, maintain insurance
in accordance with the terms set forth in Credit Agreement. All such policies of
insurance insuring the Equipment and Inventory shall be written for the benefit
of Administrative Agent for itself and the Secured Parties and each Grantor, as
their interests may appear, and shall provide for at least thirty days' prior
written notice of cancellation to Administrative Agent. Upon reasonable request
by Administrative Agent, each Grantor shall promptly furnish to Administrative
Agent evidence of such insurance in form and content satisfactory to
Administrative Agent. If any Grantor fails to perform or observe any applicable
covenants as to insurance, Administrative Agent may at its option obtain
insurance on only Lenders' interest in the Equipment and Inventory, any premium
thereby paid by Administrative Agent to become part of the Obligations, bear
interest prior to the existence of an Event of Default, at the then applicable
Base Rate, and during the existence of an Event of Default, at the Highest
Lawful Rate. If Administrative Agent maintains such substitute insurance, the
premium for such insurance shall be due on demand and payable by the applicable
Grantor to Administrative Agent. Each Grantor grants and appoints Administrative
Agent its attorney-in-fact to, if an Event of Default exists, endorse any check
or draft that may be payable to each such Grantor in order to collect any
payments in respect of insurance, including any refunds of unearned premiums in
connection with any cancellation, adjustment, or termination of any policy of
insurance. Any such sums collected by Administrative Agent shall be credited,
except to the extent applied to the purchase by Administrative Agent of similar
insurance, to any amounts then owing on the Obligations in accordance with the
Credit Agreement.

      4.8 Transfers and Other Liens. Each Grantor shall not (a) sell, assign (by
operation of Law or otherwise) or otherwise dispose of, or grant any option with
respect to, any of the Collateral, except as permitted under the Credit
Agreement and the other Loan Documents, or (b) create or permit to exist any
Lien, option, or other charge or encumbrance upon or with respect to any of the
Collateral, except for the security interest under this Agreement (and except as
provided for in the Credit Agreement and Collateral Documents).

                                       15
<PAGE>

      4.9 Administrative Agent Appointed Attorney-in-Fact. Each Grantor hereby
irrevocably appoints Administrative Agent Grantor's attorney-in-fact, with full
authority in the place and stead of each Grantor and in the name of each Grantor
or otherwise to take any action and to execute any instrument which
Administrative Agent may deem reasonably necessary or advisable to accomplish
the purposes of this Agreement, including, without limitation (provided that the
actions listed in each clause below may only be taken or exercised if an Event
of Default exists):

      (a) to obtain and adjust insurance required to be paid to Administrative
Agent pursuant to Section 4.8;

      (b) to ask, demand, collect, sue for, recover, compromise, receive, and
give acquittance and receipts for moneys due and to become due under or in
connection with the Collateral;

      (c) to receive, indorse, and collect any drafts or other Instruments,
Documents, and Chattel Paper, in connection therewith; and

      (d) to file any claims or take any action or institute any proceedings
which Administrative Agent may deem necessary or desirable for the collection of
any of the Collateral or otherwise to enforce compliance with the terms and
conditions of any Collateral or the rights of Administrative Agent with respect
to any of the Collateral. EACH GRANTOR HEREBY IRREVOCABLY GRANTS TO
ADMINISTRATIVE AGENT EACH SUCH GRANTOR'S PROXY (EXERCISABLE IF AN EVENT OF
DEFAULT EXISTS) TO VOTE ANY SECURITIES COLLATERAL AND APPOINTS ADMINISTRATIVE
AGENT EACH SUCH GRANTOR'S ATTORNEY-IN-FACT TO PERFORM ALL OBLIGATIONS OF GRANTOR
UNDER THIS AGREEMENT AND TO EXERCISE ALL OF ADMINISTRATIVE AGENT'S AND EACH
OTHER SECURED PARTY'S RIGHTS HEREUNDER. THE PROXY AND EACH POWER OF ATTORNEY
HEREIN GRANTED, AND EACH STOCK POWER AND SIMILAR POWER NOW OR HEREAFTER GRANTED
(INCLUDING ANY EVIDENCED BY A SEPARATE WRITING), ARE COUPLED WITH AN INTEREST
AND ARE IRREVOCABLE PRIOR TO FINAL PAYMENT IN FULL OF THE OBLIGATIONS.

                                   ARTICLE V

                      RIGHTS AND POWERS OF SECURED PARTIES

      5.1 Administrative Agent May Perform. If any Grantor fails to perform any
agreement contained herein and the Administrative Agent, in the exercise of its
reasonable business judgment, believes that such failure materially and
adversely affects the Collateral, its security interest or the priority or
perfection thereof, or its rights or remedies hereunder, Administrative Agent
may itself perform, or cause performance of, such agreement, and the reasonable
expenses of Administrative Agent incurred in connection therewith shall be
payable by each such Grantor under Section 5.6.

                                       16
<PAGE>

      5.2 Administrative Agent's Duties. The powers conferred on Administrative
Agent hereunder are solely to protect Lenders' interest in the Collateral and
shall not impose any duty upon it to exercise any such powers. Except for the
safe custody of any Collateral in its possession and the accounting for moneys
actually received by Lenders hereunder, neither Administrative Agent nor any
other Lender shall have any duty as to any Collateral, as to ascertaining or
taking action with respect to calls, conversions, exchanges, maturities,
tenders, or other matters relative to any Collateral, whether or not
Administrative Agent or any other Lender has or is deemed to have knowledge of
such matters, or as to the taking of any necessary steps to preserve rights
against prior parties or any other rights pertaining to any reasonable care in
the custody and preservation of any Collateral in its possession if such
Collateral is accorded treatment substantially equal to that which
Administrative Agent accords its own property. Except as provided in this
Section 5.2, neither Administrative Agent nor any other Lender shall have any
duty or liability to protect or preserve any Collateral or to preserve rights
pertaining thereto. Nothing contained in this Agreement shall be construed as
requiring or obligating Administrative Agent or any other Lender, and neither
Administrative Agent nor any other Lender shall be required or obligated, to (a)
present or file any claim or notice or take any action, with respect to any
Collateral or in connection therewith or (b) notify any Grantor of any decline
in the value of any Collateral.

      5.3 Remedies. If an Event of Default exists:

      (a) Administrative Agent may exercise in respect of the Collateral, in
addition to other rights and remedies provided for herein or otherwise available
to it or any other Lender pursuant to any applicable Law, all the rights and
remedies of a secured party on default under the Uniform Commercial Code in
effect at that time (whether or not the Uniform Commercial Code applies to the
affected Collateral), and also may require each Grantor to, and each Grantor
will at its expense and upon request of Administrative Agent forthwith, assemble
all or part of the Collateral as directed by Administrative Agent and make it
available to Administrative Agent at a place to be designated by Administrative
Agent which is reasonably convenient to both parties at public or private sale,
at any of Administrative Agent's offices or elsewhere, for cash, on credit or
for future delivery, and upon such other terms as Administrative Agent may deem
commercially reasonable. Each Grantor agrees that, to the extent notice of sale
shall be required by Law, ten days' notice to each Grantor of the time and place
of any public sale or the time after which any private sale is to be made shall
constitute reasonable notification. Administrative Agent shall not be obligated
to make any sale of Collateral regardless of notice of sale having been given.
Administrative Agent may adjourn any public or private sale from time to time by
announcement at the time and place fixed therefor, and such sale may, without
further notice, be made at the time and place to which it was so adjourned.

      (b) All cash proceeds received by Administrative Agent upon any sale of,
collection of, or other realization upon, all or any part of the Collateral
shall be applied as set forth in Section 8.03 of the Credit Agreement.

      (c) All payments received by each Grantor under or in connection with any
Collateral shall be received in trust for the benefit of Administrative Agent,
shall be segregated from other funds of each such Grantor, and shall be
forthwith paid over to Administrative Agent in the same form as so received
(with any necessary endorsement).

                                       17
<PAGE>

      (d) Because of the Securities Act of 1933, as amended ("Securities Act"),
and other Laws, including without limitation state "blue sky" Laws, or
contractual restrictions or agreements, there may be legal restrictions or
limitations affecting Administrative Agent in any attempts to dispose of the
Collateral and the enforcement of rights under this Agreement. For these
reasons, Administrative Agent is authorized by each Grantor, but not obligated,
if any Event of Default exists, to sell or otherwise dispose of any of the
Collateral at private sale, subject to an investment letter, or in any other
manner which will not require the Collateral, or any part thereof, to be
registered in accordance with the Securities Act, or any other Law.
Administrative Agent is also hereby authorized by each Grantor, but not
obligated, to take such actions, give such notices, obtain such consents, and do
such other things as Administrative Agent may deem required or appropriate under
the Securities Act or other securities Laws or other Laws or contractual
restrictions or agreements in the event of a sale or disposition of any
Collateral. Each Grantor understands that Administrative Agent may in its
discretion approach a restricted number of potential purchasers and that a sale
under such circumstances may yield a lower price for the Collateral than would
otherwise be obtainable if same were registered and/or sold in the open market.
No sale so made in good faith by Administrative Agent shall be deemed to be not
"commercially reasonable" because so made. Each Grantor agrees that if an Event
of Default exists, and Administrative Agent sells the Collateral or any portion
thereof at any private sale or sales, Administrative Agent shall have the right
to rely upon the advice and opinion of appraisers and other Persons, which
appraisers and other Persons are acceptable to Administrative Agent, as to the
best price reasonably obtainable upon such a private sale thereof. In the
absence of actual fraud, such reliance shall be prima facie evidence that
Administrative Agent and the other Secured Parties handled such matter in a
commercially reasonable manner under applicable Law.

      (e) If Administrative Agent shall determine to exercise its right to sell
any or all of the Collateral, and if in the opinion of counsel for
Administrative Agent it is necessary, or if in the reasonable opinion of
Administrative Agent it is advisable, to have the Collateral or that portion
thereof to be sold, registered under the provisions of the Securities Act, each
Grantor will, to the fullest extent it has the capability to do so, cause the
issuers of the Collateral contemplated to be sold to execute and deliver, and
cause the directors and officers of each thereof to execute and deliver, all at
Grantors' expense, all such instruments and documents, and to do or cause to be
done all such other acts and things, as may be necessary or, in the opinion of
Administrative Agent, advisable to register the Collateral or that portion
thereof to be sold, under the provisions of the Securities Act and to cause the
registration statement relating thereto to become effective and to remain
effective for such period as Administrative Agent may deem appropriate to
facilitate the sale or other disposition of such Collateral from the date of the
first public offering of the Collateral or that portion thereof to be sold, and
to make all amendments thereto and/or to the related prospectus which, in the
opinion of Administrative Agent, are necessary or advisable, all in conformity
with the requirements of the Securities Act. Each Grantor shall use its best
efforts to cause each issuer of Collateral to comply with the provisions of the
securities or "blue sky" Laws of any jurisdiction which Administrative Agent
shall designate and to cause each Issuer to make available to its security
holders, as soon as practicable, an earnings statement which will satisfy the
provisions of the Securities Act and applicable "blue sky" Laws.

                                       18
<PAGE>

      (f) After notice to Grantor, Administrative Agent and such Persons as
Administrative Agent may reasonably designate shall have the right, at Grantor's
own cost and expense, to verify under reasonable procedures, the validity,
amount, quality, quantity, value, condition, and status of, or any other matter
relating to, the Collateral, including, in the case of Accounts or Collateral in
the possession of any third person, by contacting Account Debtors or the third
person possessing such Collateral for the purpose of making such a verification.
Administrative Agent shall have the absolute right to share any information it
gains from such inspection or verification with any Secured Party.

      5.4 Appointment of Receiver or Trustee. In connection with the exercise of
Lenders' rights under this Agreement or any other Loan Document, Administrative
Agent may, if an Event of Default exists resulting in the acceleration of the
Obligations or following any Loan Party's failure to pay any of the Obligations
at maturity, obtain the appointment of a receiver or trustee to assume, upon
receipt of all necessary judicial or other Governmental Authority consents or
approvals, control of or ownership of any Permits. Such receiver or trustee
shall have all rights and powers provided to it by Law or by court order or
provided to Administrative Agent under this Agreement or any other Loan
Document. Upon the appointment of such trustee or receiver, each Grantor shall
cooperate, to the extent necessary or appropriate, in the expeditious
preparation, execution, and filing of an application to any Governmental
Authority or for consent to the transfer of control or assignment of each
Grantor's Permits to the receiver or trustee.

      5.5 Further Approvals Required.

      (a) In connection with the exercise by Administrative Agent of rights
under this Agreement that affects the disposition of or use of any Collateral,
it may be necessary to obtain the prior consent or approval of Governmental
Authorities and other Persons to a transfer or assignment of Collateral. In
connection with the exercise by Administrative Agent or any other Secured Party
of its rights relating to the disposition of or operation under any Permit, it
may be necessary to obtain the prior consent or approval of other Governmental
Authority, or other Persons to the exercise of rights with respect to the
Collateral. If an Event of Default exists, each Grantor shall execute, deliver,
and file, and hereby appoints (to the extent not prohibited by Applicable Law)
Administrative Agent as its attorney, to execute, deliver, and file on Grantor's
behalf and in Grantor's name, all applications, certificates, filings,
instruments, and other documents (including without limitation any application
for an assignment or transfer of control or ownership) that may be necessary or
appropriate, in Administrative Agent's opinion, to obtain such consents or
approvals. Each Grantor shall use its best efforts to obtain such consents or
approvals if a Default or Event of Default exists. Each Grantor acknowledges
that there is no adequate remedy at law for failure by it to comply with the
provisions of this Section 5.5(a) and that such failure would not be adequately
compensable in damages, and therefore agrees that this Section 5.5(a) may be
specifically enforced.

      (b) Each Grantor shall, if an Event of Default exists, execute, deliver,
and file, and hereby appoints Administrative Agent as its attorney-in-fact, to,
if an Event of Default exists, execute, deliver, and file on Grantor's behalf
and in Grantor's name, all applications, certificates, filings, instruments, and
other documents (including without limitation any application for an assignment
or transfer of control or ownership) that may be reasonably necessary or
appropriate,

                                       19
<PAGE>

in Administrative Agent's opinion, to obtain such consents, waivers, or
approvals. Each Grantor shall use its best efforts to obtain the foregoing
consents, waivers, and approvals, including receipt of consents, waivers, and
approvals under applicable agreements prior to a Default or Event of Default.
Each Grantor acknowledges that there is no adequate remedy at Law for failure by
it to comply with the provisions of this Section 5.5(b) and that such failure
would not be adequately compensable in damages, and therefore agrees that this
Section 5.5(b) may be specifically enforced.

      5.6 INDEMNITY AND EXPENSES

      (a) EACH GRANTOR SHALL INDEMNIFY (WHICH SHALL BE PAYABLE FROM TIME TO TIME
ON DEMAND) SECURED PARTIES FROM AND AGAINST ANY AND ALL CLAIMS, LOSSES, AND
LIABILITIES (INCLUDING REASONABLE ATTORNEYS' FEES) GROWING OUT OF OR RESULTING
FROM THIS AGREEMENT (INCLUDING ENFORCEMENT OF THIS AGREEMENT), EXPRESSLY
INCLUDING SUCH CLAIMS, LOSSES, OR LIABILITIES ARISING OUT OF MERE NEGLIGENCE OF
ANY SECURED PARTY, EXCEPT CLAIMS, LOSSES, OR LIABILITIES RESULTING FROM ANY
SECURED PARTY'S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.

      (b) EACH GRANTOR WILL UPON DEMAND PAY TO EACH SECURED PARTY THE AMOUNT OF

PRESERVATION, USE OR OPERATION OF, OR THE SALE OF, COLLECTION FROM, OR OTHER
REALIZATION UPON, ANY OF THE COLLATERAL, (III) THE EXERCISE OR ENFORCEMENT OF
ANY OF THE RIGHTS OF ANY SECURED PARTY HEREUNDER, OR (IV) THE FAILURE BY GRANTOR
TO PERFORM OR OBSERVE ANY OF THE PROVISIONS HEREOF.

                                   ARTICLE VI

                                  MISCELLANEOUS

      6.1 Maximum Liability. Anything in this Agreement to the contrary
notwithstanding, the obligations of each Grantor (other than Borrower) hereunder
shall be limited to a maximum aggregate amount equal to the largest amount that
would not render its obligations hereunder subject to avoidance as a fraudulent
transfer or conveyance under Section 548 of Title 11 of the United States Code
or any applicable provisions of comparable Law (collectively, the "Fraudulent
Transfer Laws"), in each case after giving effect to all other liabilities of
each Grantor, contingent or otherwise, that are relevant under the Fraudulent
Transfer Laws (specifically excluding, however, any liabilities of each Grantor
in respect of intercompany indebtedness to other Loan Parties or Affiliates of
other Loan Parties to the extent that such indebtedness would be discharged in
an amount equal to the amount paid or property conveyed by each Grantor under
the Loan Documents) and after giving effect as assets, subject to Section 6.2,
to the value (as determined under the applicable provisions of the Fraudulent

                                       20
<PAGE>
Transfer Laws) of any rights to subrogation or contribution of each Grantor
pursuant to (a) Applicable Law or (b) any agreement providing for an equitable
allocation among each Grantor and other Loan Parties of obligations arising
under the Loan Documents.

      6.2 Waiver of Subrogation. Each Grantor shall not assert, enforce, or
otherwise exercise (a) any right of subrogation to any of the rights or Liens of
any Secured Creditor or any other beneficiary against any other Loan Party or
any Collateral or other security, or (b) any right of recourse, reimbursement,
contribution, indemnification, or similar right against any other Loan Party on
all or any part of the Obligations or any other Loan Party, and each Grantor
hereby waives any and all of the foregoing rights and the benefit of, and any
right to participate in, and Collateral or other security given to or for the
benefit of any Secured Creditor or any other beneficiary to secure payment of
the Obligations. This Section 6.2 shall survive the termination of this
Agreement, and any satisfaction and discharge of each Grantor by virtue of any
payment, court order, or Law.

      6.3 Cumulative Rights. All rights of Administrative Agent and each Secured
Creditor under the Loan Documents are cumulative of each other and of every
other right which Administrative Agent and each Secured Creditor may otherwise
have at Law or in equity or under any other agreement. The exercise of one or
more rights shall not prejudice or impair the concurrent or subsequent exercise
of other rights.

      6.4 Amendments; Waivers. Any term, covenant, agreement, or condition of
this Agreement may be amended, and any right under this Agreement may be waived,
if, but only if, such amendment or waiver is in writing and is signed by
Administrative Agent and, in the case of an amendment, by each Grantor. Unless
otherwise specified in such waiver, a waiver of any right under this Agreement
shall be effective only in the specific instance and for the specific purpose
for which given. No election not to exercise, failure to exercise or delay in
exercising any right, nor any course of dealing or performance, shall operate as
a waiver of any right of any Lender under this Agreement or Applicable Law, nor
shall any single or partial exercise of any such right preclude any other or
further exercise thereof or the exercise of any other right of any Secured
Creditor under this Agreement or Applicable Law.

      6.5 Continuing Security Interest. This Agreement creates a continuing
security interest in the Collateral and shall (a) remain in full force and
effect until the later of (i) the Obligations are fully, indefeasibly,
absolutely and unconditionally paid (other than indemnity obligations that
survive the termination of this Agreement for which no notice of a claim has
been received by Grantor) and (ii) the expiration of the obligation of all
Secured Creditors to extend credit to each Grantor, (b) be binding upon each
Grantor, its successors and assigns, and (c) inure to the benefit of, and be
enforceable by, Administrative Agent and its successors, transferees and
assigns. At such time as the Obligations are fully, indefeasibly, absolutely and
unconditionally paid (other than indemnity obligations that survive the
termination of this Agreement for which no notice of a claim has been received
by Grantor) and all obligations of all Secured Creditors to extend credit to
each Grantor have expired, Administrative Agent will, at Grantor's expense,
execute and deliver to each Grantor such documents as each such Grantor shall
reasonably request to evidence such payment. Each Grantor agrees that to the
extent that Administrative Agent or any Secured Creditor receives any payment or
benefit and such payment or benefit, or any part thereof, is subsequently
invalidated, declared to be fraudulent or

                                       21
<PAGE>

preferential, set aside or is required to be repaid to a trustee, receiver, or
any other Person under any Debtor Relief Law, common law or equitable cause,
then to the extent of such payment or benefit, the Obligations or part thereof
intended to be satisfied shall be revived and continued in full force and effect
as if such payment or benefit had not been made and, further, any such repayment
by Administrative Agent or any Secured Creditor, to the extent that
Administrative Agent or any Secured Creditor did not directly receive a
corresponding cash payment, shall be added to and be additional Obligations
payable upon demand by Administrative Agent or any Secured Creditor and secured
hereby, and, if the lien and security interest hereof shall have been released,
such lien and security interest shall be reinstated with the same effect and
priority as on the date of execution hereof all as if no release of such lien or
security interest had ever occurred.

SERVICE OF PROCESS.

HAVE TO THE BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT
OF ANY LOAN DOCUMENT OR OTHER DOCUMENT RELATED THERETO. THE GRANTOR, THE

ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH OR RELATED

<PAGE>

DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE WHETHER NOW EXISTING
OR HEREAFTER ARISING, AND WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND
EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY
PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES

PARTIES' RIGHTS HEREUNDER and (c) all rights of redemption, appraisement or

remain in full force and effect without regard to, and shall not be impaired or

invalid, or unenforceable provision or by its severance herefrom. Furthermore,

      6.12 Arbitration.

      (a) Arbitration. Upon the demand of any party, any Dispute shall be
resolved by binding arbitration in accordance with the terms of this Agreement.
A "Dispute" shall mean any action, dispute, claim or controversy of any kind,
whether in contract or tort, statutory or common law, legal or equitable, now
existing or hereafter arising under or in connection with, or in any way
pertaining to, this Agreement, or any past, present or future extensions of
credit and other activities, transactions or obligations of any kind related
directly or indirectly to this Agreement, including without limitation, any of
the foregoing arising in connection with the exercise of any self-help,
ancillary or other remedies pursuant to this Agreement. Any party may by summary
proceedings bring an action in court to compel arbitration of a Dispute. Any
party who fails or refuses to submit to arbitration following a lawful demand by
any other party shall bear all costs and expenses incurred by such other party
in compelling arbitration of any Dispute.

      (b) Governing Rules. Arbitration proceedings shall be administered by the
American Arbitration Association ("AAA") or such other administrator as the
parties shall mutually agree upon in accordance with the AAA Commercial
Arbitration Rules. All Disputes submitted to arbitration shall be resolved in
accordance with the Federal Arbitration Act (Title 9 of the United States Code),
notwithstanding any conflicting choice of law provision in this Agreement. The
arbitration shall be conducted at a location in Dallas, Texas selected by the
AAA or other administrator. If there is any inconsistency between the terms
hereof and any such rules, the terms and procedures set forth herein shall
control. All statutes of limitation applicable to any

                                       25
<PAGE>

Dispute shall apply to any arbitration proceeding. All discovery activities
shall be expressly limited to matters directly relevant to the Dispute being
arbitrated. Judgment upon any award rendered in an arbitration may be entered in
any court having jurisdiction; provided however, that nothing contained herein
shall be deemed to be a waiver by any party that is a bank of the protections
afforded to it under 12 U.S.C. Section 91 or any similar applicable state law.

      (c) No Waiver; Provisional Remedies, Self-Help and Foreclosure. No
provision hereof shall limit the right of any party to exercise self-help
remedies such as setoff, foreclosure against or sale of any real or personal
property collateral or security, or to obtain provisional or ancillary remedies,
including without limitation injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding. The exercise of any such remedy shall not waive the right of any
party to compel arbitration hereunder.

      (d) Arbitrator Qualifications and Powers Awards. Arbitrators must be
active members of the State Bar of Texas with expertise in the substantive laws
applicable to the subject matter of the Dispute. Arbitrators are empowered to
resolve Disputes by summary rulings in response to motions filed prior to the
final arbitration hearing. Arbitrators (i) shall resolve all Disputes in
accordance with the substantive law of the state of Texas, (ii) may grant any
remedy or relief that a court of the state of Texas could order or grant within
the scope hereof and such ancillary relief as is necessary to make effective any
award, and (iii) shall have the power to award recovery of all costs and fees,
to impose sanctions and to take such other actions as they deem necessary to the
same extent a judge could pursuant to the Federal Rules of Civil Procedure, the
Texas Rules of Civil Procedure or other applicable law. Any Dispute in which the
amount in controversy is $5,000,000 or less shall be decided by a single
arbitrator who shall not render an award of greater than $5,000,000 (including
damages, costs, fees and expenses). By submission to a single arbitrator, each
party expressly waives any right or claim to recover more than $5,000,000. Any
Dispute in which the amount in controversy exceeds $5,000,000 shall be decided
by majority vote of a panel of three arbitrators; provided however, that all
three arbitrators must actively participate in all hearings and deliberations.

      (e) Judicial Review. Notwithstanding anything herein to the contrary, in
any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law. In such arbitrations (i) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
Texas, and (iii) the parties shall have in addition to the grounds referred to
in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
Texas. Judgment confirming an award in such a proceeding may be entered only if
a court determines the award is supported by substantial evidence and not based
on legal error under the substantive law of the state of Texas.

      (f) Miscellaneous. To the maximum extent practicable, the AAA, the
arbitrators and the parties shall take all action required to conclude any
arbitration proceedings within 180 days

                                       26
<PAGE>

of the filing of the Dispute with the AAA. No arbitrator or other party to an
arbitration proceeding may disclose the existence, content or results thereof,
except for disclosures of information by a party required in the ordinary course
of its business, by applicable law or regulations, or to the extent necessary to
exercise any judicial review rights set forth herein. If more than one agreement
for arbitration by or between the parties potentially applies to a Dispute, the
arbitration provisions most directly related to this Agreement or the subject
matter of the Dispute shall control. This arbitration provision shall survive
termination, amendment or expiration of this Agreement or any relationship
between the parties.

      6.13 ENTIRE AGREEMENT. THIS WRITTEN AGREEMENT, TOGETHER WITH THE OTHER
LOAN PAPERS, 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 AMONG THE
