Borrower and the Borrower may borrow, repay, and reborrow from time to time
between the Closing Date and the Maturity Date upon notice by the Borrower to
the Agent given in accordance with Section 2.6, such sums as are requested by
the Borrower up to a maximum aggregate amount outstanding (after giving effect
to all amounts requested) at any one time equal to such Bank's Commitment minus
such Bank's Commitment Percentage of the sum of the Maximum Drawing Amount and
all Unpaid Reimbursement Obligations and such Bank's Commitment Percentage of
any then-outstanding Swingline Loans, provided that the sum of the outstanding
amount of the Revolving Credit Loans (after giving effect to all amounts
requested) plus the Maximum Drawing Amount, the then-outstanding amount of any
Swingline Loans, and all Unpaid Reimbursement Obligations shall not at any time
exceed the Total Commitment. The Revolving Credit Loans shall be made pro rata
in accordance with each Bank's Commitment Percentage. Each request for a
Revolving Credit Loan hereunder shall constitute a representation and warranty
by the Borrower that the conditions set forth in Section 12 have been satisfied
on the date of such request.

      2.2. COMMITMENT FEE. The Borrower agrees to pay to the Agent for the
accounts of the Banks in accordance with their respective Commitment Percentages
a Commitment Fee (each a "Commitment Fee" and, in the aggregate, the "Commitment
Fee") calculated as follows, in each case effective from the date on which the
Agent receives the applicable Compliance Certificate: (i) at any time when the
Leverage Ratio calculated as of the end of the previous


                                       13
   14
quarter was equal to or less than .25, eighteen one-hundredths of one percent
(.18%) per annum; (ii) at any time when the Leverage Ratio calculated as of the
end of the previous quarter was greater than .25 but less than .50, twenty
one-hundredths of one percent (.20%) per annum; and (iii) at any time when the
Leverage Ratio calculated as of the end of the previous quarter was equal to or
greater than .50, one-quarter of one percent (.25%) per annum, in each case
calculated on the average daily amount during each calendar quarter, or such
shorter period as may exist from the Closing Date to the first immediately
succeeding end of a calendar quarter or from the end of the final calendar
quarter occurring prior to the Maturity Date until the Maturity Date, by which
the Total Commitment minus the sum of the Maximum Drawing Amount and all Unpaid
Reimbursement Obligations exceeds the outstanding amount of Revolving Credit
Loans during such calendar quarter. The Commitment Fee shall be payable
quarterly in arrears on the first day of each calendar quarter for the
immediately preceding calendar quarter commencing on the first such date
following the date hereof, with a final payment on the earlier to occur of (i)
the Maturity Date and (ii) any earlier date on which the Commitments shall
terminate pursuant hereto.

      2.3. REDUCTION OF TOTAL COMMITMENT. The Borrower shall have the right, at
any time and from time to time, upon two (2) Business Days' prior written notice
to the Agent, to reduce by $500,000 or an integral multiple thereof, or
terminate entirely, the Total Commitment, whereupon the Commitments of the Banks
shall be reduced pro rata in accordance with their respective Commitment
Percentages of the amount specified in such notice or, as the case may be,
terminated. The Total Commitment may not at any time be reduced below the amount
of any Swingline Loans outstanding at the time of such reduction or termination.
Promptly after receiving any notice of the Borrower delivered pursuant to this
Section 2.3, the Agent will notify the Banks of the substance thereof. Upon the
effective date of any such reduction or termination, the Borrower shall pay to
the Agent for the respective accounts of the Banks the full amount of any
Commitment Fee then accrued on the amount of the reduction. No reduction or
termination of the Commitments may be reinstated.

      2.4. THE REVOLVING CREDIT NOTES. The Revolving Credit Loans shall be
evidenced by separate restated promissory notes of the Borrower, each in
substantially the form of Exhibit A hereto (each a "Revolving Credit Note"),
dated the Closing Date (or such other date on which a Bank may become a party
hereto pursuant to Section 19 hereof) and completed with appropriate insertions.
One Revolving Credit Note shall be payable to the order of each Bank in a
principal amount equal to such Bank's Commitment or, if less, the outstanding
amount of all Revolving Credit Loans made by such Bank, plus interest accrued
thereon, as set forth below. The Borrower irrevocably authorizes each Bank to
make or cause to be made, at or about the time of the Drawdown Date of any
Revolving Credit Loan or at the time of receipt of any payment of principal on
such Bank's Revolving Credit Note, an appropriate notation on such Bank's
Revolving Credit Note Record reflecting the making of such Revolving Credit Loan
or (as the case may be) the receipt of such payment. The outstanding amount of
the Revolving Credit Loans set forth on such Bank's Revolving Credit Note Record
shall be prima facie evidence of the principal amount thereof owing and unpaid
to such Bank, but the failure to record, or any error in so recording, any such
amount on such Bank's Revolving Credit Note Record shall not limit or otherwise
affect the obligations of the Borrower hereunder or under any Revolving


                                       14
   15
Credit Note to make payments of principal of or interest on any Revolving Credit
Note when due.

Section 6.10,

            (a) Each Base Rate Loan shall bear interest for the period
      commencing with the Drawdown Date thereof and ending on the last day of
      the Interest Period with respect thereto at a rate per annum equal to the
      Base Rate;

            (b) Each LIBOR Rate Loan shall bear interest for the period
      commencing with the Drawdown Date thereof and ending on the last day of
      the Interest Period with respect thereto at the rate per annum equal to
      the LIBOR Rate determined for such Interest Period plus the applicable
      LIBOR Spread;

            (c) The Borrower promises to pay interest on each Revolving Credit
      Loan, in arrears, on each Interest Payment Date with respect thereto.

      2.6. REQUESTS FOR REVOLVING CREDIT LOANS. The Borrower shall give to the
Agent written notice in the form of Exhibit B hereto (or telephonic notice
confirmed in a writing in the form of Exhibit B hereto) of each Revolving Credit
Loan requested hereunder (a "Loan Request") no less than (i) one (1) Business
Day prior to the proposed Drawdown Date of any Base Rate Loan and (ii) three (3)
LIBOR Business Days prior to the proposed Drawdown Date of any LIBOR Rate Loan.
Each such notice shall specify (A) the aggregate principal amount of the
Revolving Credit Loans requested, (B) the proposed Drawdown Date of such
Revolving Credit Loans, (C) the Interest Period for such Revolving Credit Loans,
and (D) the Type of such Revolving Credit Loans. Promptly upon receipt of any
such notice, the Agent shall notify each of the Banks thereof. Each Loan Request
shall be irrevocable and binding on the Borrower and shall obligate the Borrower
to accept the Revolving Credit Loans requested from the Banks on the proposed
Drawdown Date. Each Loan Request with respect to Base Rate Loans shall be in a
minimum aggregate amount of $500,000 or an integral multiple thereof and each
Loan Request in respect of LIBOR Rate Loans shall be in a minimum aggregate
amount of $1,000,000 or an integral multiple thereof.

      2.7. CONVERSION OPTIONS.

            2.7.1. CONVERSION TO DIFFERENT TYPE OF REVOLVING CREDIT LOAN. The
      Borrower may elect from time to time to convert any outstanding Revolving
      Credit Loan to a Revolving Credit Loan of another Type, provided that (i)
      with respect to any such conversion of a LIBOR Rate Loan to a Base Rate
      Loan, the Borrower shall give the Agent at least one (1) Business Day's
      prior written notice of such election; (ii) with respect to any such
      conversion of a Base Rate Loan to a LIBOR Rate Loan, the Borrower shall
      give the Agent at least three (3) LIBOR Business Days' prior written
      notice of such election; (iii) with respect to any such conversion of a
      LIBOR Rate Loan into a Base Rate Loan, such conversion shall only be made
      at the end of business on the last day of the Interest Period with respect
      thereto; (iv) no more than three (3) LIBOR Rate Loans having different
      Interest Rate Periods may be outstanding at any time; and (v) no Loan may
      be converted into a LIBOR Rate Loan when any Default or Event of Default
      has

                                       15
   16
      occurred and is continuing. On the date on which such conversion is
      being made each Bank shall take such action as is necessary to transfer
      its Commitment Percentage of such Revolving Credit Loans to its Domestic
      Lending Office or its LIBOR Lending Office, as the case may be. All or any
      part of outstanding Revolving Credit Loans of any Type may be converted
      into a Revolving Credit Loan of another Type as provided herein, provided
      that any partial conversion shall be in an aggregate principal amount of
      $500,000 (subject to Section 2.7.3 hereof) or a whole multiple thereof.
      Each Conversion Request relating to the conversion of a Base Rate Loan to
      a LIBOR Rate Loan shall be irrevocable by the Borrower.

            2.7.2. CONTINUATION OF TYPE OF REVOLVING CREDIT LOAN. Any Revolving
      Credit Loan of any Type may be continued as a Revolving Credit Loan of the
      same Type upon the expiration of an Interest Period with respect thereto
      by compliance by the Borrower with the notice provisions contained in
      Section 2.7.1; provided that no LIBOR Rate Loan may be continued as such
      when any Default or Event of Default has occurred and is continuing, but
      shall be automatically converted to a Base Rate Loan at the end of
      business on the last day of the first Interest Period relating thereto
      ending during the continuance of any Default or Event of Default of which
      officers of the Agent active in respect of the Borrower's account have
      actual knowledge. In the event that the Borrower fails to provide any such
      notice with respect to the continuation of any LIBOR Rate Loan as such,
      then such LIBOR Rate Loan shall be automatically converted to a Base Rate
      Loan at the end of business on the last day of the first Interest Period
      relating thereto. The Agent shall notify the Banks promptly when any such
      automatic conversion contemplated by this Section 2.7.2 is scheduled to
      occur.

            2.7.3. LIBOR RATE LOANS. Any conversion to or from LIBOR Rate Loans
      shall be in such amounts and be made pursuant to such elections so that,
      after giving effect thereto, the aggregate principal amount of all LIBOR
      Rate Loans having the same Interest Period shall not be less than
      $5,000,000 or a whole multiple of $1,000,000 in excess thereof.

      2.8. FUNDS FOR REVOLVING CREDIT LOAN.

            2.8.1. FUNDING PROCEDURES. Not later than 11:00 a.m. (California
      time) on the proposed Drawdown Date of any Revolving Credit Loans, each of
      the Banks will make available to the Agent, at its Head Office, in
      immediately available funds, the amount of such Bank's Commitment
      Percentage of the aggregate amount of the requested Revolving Credit
      Loans. Upon receipt from each Bank of such amount, and upon receipt of the
      documents required by Sections 11 and 12 and the satisfaction of the other
      conditions set forth therein, to the extent applicable, the Agent will
      make available to the Borrower the aggregate amount of such Revolving
      Credit Loans made available to the Agent by the Banks. The failure or
      refusal of any Bank to make available to the Agent at the aforesaid time
      and place on any Drawdown Date the amount equal to its Commitment
      Percentage of the aggregate amount of the requested Revolving Credit Loans
      shall not relieve any other Bank from its several obligation hereunder to
      make available to the Agent the


                                       16
   17
      amount equal to such other Bank's Commitment Percentage of the aggregate
      amount of any requested Revolving Credit Loans.

            2.8.2. ADVANCES BY AGENT. The Agent may, unless notified to the
      contrary by any Bank prior to a Drawdown Date, assume that such Bank has
      made available to the Agent on such Drawdown Date the amount equal to such
      Bank's Commitment Percentage of the aggregate Revolving Credit Loans to be
      made on such Drawdown Date, and the Agent may (but it shall not be
      required to), in reliance upon such assumption, make available to the
      Borrower a corresponding amount. If any Bank makes available to the Agent
      such amount on a date after such Drawdown Date, such Bank shall pay to the
      Agent, on demand, an amount equal to the product of (i) the average
      computed for the period referred to in clause (iii) of this sentence, of
      the weighted average interest rate paid by the Agent for federal funds
      acquired by the Agent during each day included in such period, times (ii)
      the amount equal to such Bank's Commitment Percentage of such Revolving
      Credit Loans, times (iii) a fraction, the numerator of which is the number
      of days that elapse from and including such Drawdown Date to the date on
      which the amount equal to such Bank's Commitment Percentage of such
      Revolving Credit Loans shall become immediately available to the Agent,
      and the denominator of which is 365. A statement of the Agent submitted to
      such Bank with respect to any amounts owing under this Section 2.8.2 shall
      be prima facie evidence of the amount due and owing to the Agent by such
      Bank. If the amount equal to such Bank's Commitment Percentage of such
      Revolving Credit Loans is not made available to the Agent by such Bank
      within three (3) Business Days following such Drawdown Date, the Agent
      shall be entitled to recover (a) such amount from the Banks (excluding the
      Delinquent Bank) on a pro rata basis up to each Bank's Commitment
      Percentage of such amount); provided that in no event shall any Bank be
      required to advance more than the difference between such Bank's
      Commitment in effect at such time minus the sum equal to its Commitment
      Percentage of (i) all Revolving Credit Loans then outstanding, plus (ii)
      the Maximum Drawing Amount plus (iii) all Unpaid Reimbursement
      Obligations) plus (iv) any then-outstanding Swingline Loans and (b) any
      amount not recovered pursuant to the foregoing clause (a) from the
      Borrower on demand, with interest thereon at the rate per annum applicable
      to the Revolving Credit Loans made on such Drawdown Date.

3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

      3.1. MATURITY. The Borrower promises to pay on the Maturity Date, and
there shall become absolutely due and payable on the Maturity Date, all of the
Revolving Credit Loans outstanding on such date, together with any and all
accrued and unpaid interest thereon.

      3.2. MANDATORY REPAYMENTS OF REVOLVING CREDIT LOANS. If at any time the
sum of the outstanding amount of the Revolving Credit Loans, the Maximum Drawing
Amount, any Swingline Loans, and all Unpaid Reimbursement Obligations exceeds
the amount of the Total Commitment, then the Borrower shall immediately and
without demand therefor pay the amount of such excess to the Agent for the
respective accounts of the Banks for application: first, to any Unpaid
Reimbursement Obligations; second to the Swingline Loans, third to the Revolving
Credit Loans; and fourth, to provide to the Agent cash collateral for
Reimbursement Obligations


                                       17
   18
as contemplated by Sections 5.2(b) and (c). Each payment of any Unpaid
Reimbursement Obligations or prepayment of Revolving Credit Loans shall be
allocated among the Banks, in proportion, as nearly as practicable, to each
Unpaid Reimbursement Obligation or (as the case may be) the respective unpaid
principal amount of each Bank's Revolving Credit Note, with adjustments to the
extent practicable to equalize any prior payments or repayments not exactly in
proportion.

      3.3. OPTIONAL REPAYMENTS OF REVOLVING CREDIT LOANS.

            3.3.1. REPAYMENTS OF BASE RATE LOANS. The Borrower shall have the
      right, at its election, to repay the outstanding amount of the Base Rate
      Loans, as a whole or in part, at any time without penalty or premium. The
      Borrower shall give the Agent, no later than 11:00 a.m., California time,
      at least one (1) Business Day's prior written notice of any proposed
      prepayment pursuant to this Section 3.3.1 of such Base Rate Loans,
      specifying the proposed date of prepayment of Base Rate Loans and the
      principal amount to be prepaid. Accrued but unpaid interest on amounts
      repaid pursuant to this Section 3.3.1 shall be payable on the
      next-occurring Interest Payment Date in accordance with Section 2.5(c).
      Each such repayment of Base Rate Loans shall be in an integral multiple of
      $500,000 and shall be allocated among the Banks, in proportion, as nearly
      as practicable, to the respective unpaid principal amount of each Bank's
      Revolving Credit Note, with adjustments to the extent practicable to
      equalize any prior repayments not exactly in proportion.

            3.3.2. PREPAYMENT OF LIBOR LOANS. The Borrower shall have the right,
      at its election, to prepay the outstanding amount of any LIBOR Rate Loans,
      as a whole or in part, at any time, provided that any full or partial
      prepayment of the outstanding amount of any LIBOR Rate Loans pursuant to
      this Section 3.3.2 made on any day other than the last day of the Interest
      Period relating thereto shall be accompanied by tender of all costs
      incurred by the Bank Agents and the Banks as a result thereof, including
      reasonable costs of redeployment of funds. The Borrower shall give the
      Agent, no later than 11:00 a.m., California time, at least three (3) LIBOR
      Business Days' notice of any proposed prepayment pursuant to this Section
      3.3.2 of LIBOR Rate Loans, specifying the proposed date of prepayment and
      the principal amount to be prepaid. Each such prepayment of the LIBOR Rate
      Loans shall be in an integral multiple of $500,000, shall be accompanied
      by the payment of costs, as described in this Section 3.3.2, and of
      accrued but unpaid interest on the principal prepaid to the date of
      prepayment. Each partial prepayment shall be allocated among the Banks, in
      proportion, as nearly as practicable, to the respective unpaid principal
      amount of each Bank's Revolving Credit Note, with adjustments to the
      extent practicable to equalize any prior repayments not exactly in
      proportion.

4. THE SWINGLINE LOANS.

      4.1. COMMITMENT TO LEND. Subject to the terms and conditions set forth in
this Credit Agreement, theSwingline Lender severally agrees to lend to the
Borrower, and the Borrower may borrow, repay, and reborrow from time to time
between the Closing Date and the Swingline Maturity Date upon notice by the
Borrower to the Swingline Lender given in accordance with Section 4.4, such sums
as are requested by Borrower (each a "Swingline Loan") up to a maximum aggregate
amount outstanding (after giving effect to all amounts requested) at any one
time equal to the Swingline Commitment, provided that the sum of the outstanding
amount


                                       18
   19
 of the Swingline Loans (after giving effect to all amounts requested),
plus the then-outstanding aggregate amount of all of the Revolving Credit Loans,
plus the Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall
not at any time exceed the Total Commitment. Each request for a Swingline Loan
hereunder shall constitute a representation and warranty by the Borrower that
the conditions set forth in Section 12 have been satisfied on the date of such
request.

      4.2. THE SWINGLINE NOTE. The Swingline Loan shall be evidenced by a
promissory note of the Borrower in substantially the form of Exhibit C hereto
(the "Swingline Note"), dated the Closing Date and completed with appropriate
insertions. The Swingline Note shall be payable to the order of the Swingline
Lender in a principal amount equal to the Swingline Commitment. The Borrower
irrevocably authorizes the Swingline Lender to make or cause to be made, at or
about the time of the Drawdown Date of any Swingline Loan or at the time of
receipt of any payment of principal on the Swingline Note, an appropriate
notation on the Swingline Lender's Swingline Note Record reflecting the making
of such Swingline Loan or (as the case may be) the receipt of such payment. The
outstanding amount of the Swingline Loans set forth on the Swingline Lender's
Swingline Note Record shall be prima facie evidence of the principal amount
thereof owing and unpaid to the Swingline Lender, but the failure to record, or
any error in so recording, any such amount on the Swingline Lender's Swingline
Note Record shall not limit or otherwise affect the obligations of the Borrower
hereunder or under the Swingline Note to make payments of principal of or
interest on the Swingline Note when due.

      4.3. INTEREST ON SWINGLINE LOANS. Except as otherwise provided in Section
6.10, each Swingline Loan shall bear interest for the period commencing with the
Drawdown Date thereof and ending on the date of repayment thereof at a rate per
annum equal to the Base Rate. The Borrower promises to pay interest on each
Swingline Loan in arrears on the earlier to occur of (a) the day on which such
Swingline Loan is repaid and (b) the next occurring Interest Payment Date for
Base Rate Loans.

      4.4. REQUESTS FOR SWINGLINE LOANS. The Borrower shall give to the Agent
written notice in the form of Exhibit B hereto (or telephonic notice confirmed
in a writing in the form of Exhibit B hereto) of each Swingline Loan requested
hereunder (a "Swingline Loan Request") no later than 11:00 a.m., California
time, on the proposed Drawdown Date of any Swingline Loan. Each such notice
shall specify (A) the principal amount of the Swingline Loan requested, and (B)
the proposed Drawdown Date of such Swingline Loan. At any time when the Agent is
not a Swingline Lender, the Agent shall promptly give the Swingline Lender
written notice (or telephonic notice promptly confirmed in writing) of each
proposed borrowing of Swingline Loans and of the other matters covered by the
Swingline Loan Request. Each Swingline Loan Request shall be irrevocable and
binding on the Borrower and shall obligate the Borrower to accept the Swingline
Loan requested from the Swingline Lender on the proposed Drawdown Date. Each
Swingline Loan Request shall be in a minimum amount of $10,000 or an integral
multiple thereof. Swingline Lender will use its best effort to honor each
Swingline Loan Request that is timely made pursuant to the terms hereof, but
Borrower agrees and acknowledges that the Swingline Lender shall incur no
liability as a result of its inability to fund the amount requested in any
Swingline Loan Request until the Business Day following the day on which such
Swingline Loan Request is made.

      4.5. LIMITATIONS ON SWINGLINE LENDER'S OBLIGATION TO MAKE SWINGLINE LOANS.
The Swingline Lender will not make any Swingline Loan after it has received
written notice from the Majority Lenders that one or more of the applicable
conditions precedent set forth in Section 12 are not then satisfied (provided
that the delivery and receipt of such written notice shall not limit, affect or
modify the Banks' obligations in respect of a Mandatory Borrowing in respect of
any Swingline Loan made prior to the receipt of such notice, as specified in
Section 4.6). In addition, at any time when there is a Delinquent Bank, the
Swingline Lender shall not be required to make a Swingline Loan exceeding the
aggregate unused Commitments of the Banks other than the Delinquent Bank, unless
the Swingline Lender has entered into arrangements satisfactory to it and the
Borrower to eliminate the Swingline Lender's risk with respect to the
participation in Mandatory Borrowings by the Delinquent Bank or Banks, including
by cash collateralizing same.

      4.6. MANDATORY BORROWINGS. On any Business Day, either the Borrower or the
Swingline Lender may, in its sole discretion, give notice to Agent pursuant to
Section 2.6 that all then outstanding Swingline Loans shall be funded with a
borrowing of Revolving Credit Loans (provided that such notice shall be deemed
to have been automatically given by the Swingline Lender upon the occurrence of
a Default), in which case a borrowing of Revolving Credit Loans constituting
Base Rate Loans (each such borrowing, a "Mandatory Borrowing") shall be made on
the Drawdown Date set forth in the notice of such Mandatory Borrowing, by all
Banks pro rata in accordance with each Bank's Commitment Percentage, and the
proceeds thereof shall be applied directly to repay the Swingline Lender for all
outstanding Swingline Loans. Each Bank hereby irrevocably agrees to make
Revolving Credit Loans pursuant to each Mandatory Borrowing in the amount and in
the manner specified in the preceding sentence, and on the date specified in
writing by the Swingline Lender, notwithstanding (i) whether any conditions
specified in Section 12 are then satisfied; (ii) whether a Default or Event of
Default has occurred and is continuing; (iii) the date of such Mandatory
Borrowing; and (iv) any reduction in the Commitments after any such Swingline
Loans were made. In the event that any Mandatory Borrowing cannot for any reason
be made on the date otherwise required above (including, without limitation, as
a result of the commencement of a case under the Bankruptcy Code in respect of
Borrower), each Bank (other than the Swingline Lenders) hereby agrees that it
will forthwith purchase from the Swingline Lenders (without recourse or
warranty) such assignment of their outstanding Swingline Loans as shall be
necessary to cause the Banks to share in such Swingline Loans ratably based upon
their respective Commitment Percentages, provided that all interest payable on
such Swingline Loans shall be for the account of the Swingline Lenders until the
date the respective assignment is purchased and, to the extent attributable to
the purchased assignment, shall be payable to the Bank purchasing such
assignment from and after the date of purchase. Each Bank's obligations under
this Section 4.6 shall be absolute and unconditional.

5. LETTERS OF CREDIT.

      5.1. LETTER OF CREDIT COMMITMENTS.

            5.1.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the terms
      and conditions hereof and the execution and delivery by the Borrower of a
      fully-completed and executed letter of credit application on the Issuing
      Bank's customary form (a "Letter


                                       20
   21
      of Credit Application"), the Issuing Bank on behalf of the Banks and in
      reliance upon the agreement of the Banks set forth in Section 5.1.4 and
      upon the representations and warranties of the Borrower contained herein,
      agrees, in its individual capacity, to issue, extend and renew for the
      account of the Borrower one or more standby or documentary letters of
      credit (individually, a "Letter of Credit"), in such form as may be
      requested from time to time by the Borrower and agreed to by the Issuing
      Bank; provided, however, that, after giving effect to such request, (a)
      the sum of the aggregate Maximum Drawing Amount and all Unpaid
      Reimbursement Obligations shall not exceed $10,000,000 at any one time and
      (b) the sum of (i) the Maximum Drawing Amount, (ii) all Unpaid
      Reimbursement Obligations, and (iii) the amount of all Revolving Credit
      Loans and Swingline Loans outstanding shall not exceed the Total
      Commitment. Upon receipt of a Letter of Credit Application, the Issuing
      Bank shall notify the Agent of such request for the issuance, extension or
      renewal of a Letter of Credit, and the Agent shall confirm to the Issuing
      Bank that after giving effect to such request, the sum of the Maximum
      Drawing Amount plus all Unpaid Reimbursement Obligations plus all
      outstanding Revolving Credit Loans, plus all outstanding Swingline Loans
      does not exceed the Total Commitment. Notwithstanding the foregoing, the
      Issuing Bank shall have no obligation to issue any Letter of Credit to
      support or secure any Indebtedness of the Borrower or any of its
      Subsidiaries to the extent that such Indebtedness was incurred prior to
      the proposed issuance date of such Letter of Credit, unless in any such
      case the Borrower demonstrates to the satisfaction of the Issuing Bank
      that (x) such prior incurred Indebtedness was then fully-secured by a
      perfected and unavoidable security interest in collateral provided by the
      Borrower or such Subsidiary to the proposed beneficiary of such Letter of
      Credit or (y) such prior incurred Indebtedness was then secured or
      supported by a letter of credit issued for the account of the Borrower or
      such Subsidiary and the reimbursement obligation with respect to such
      letter of credit was fully-secured by a perfected and unavoidable security
      interest in collateral provided to the issuer of such letter of credit by
      the Borrower or such Subsidiary. Neither Issuing Bank shall issue any
      Letter of Credit after it has received written notice from the Majority
      Lenders that one or more of the applicable conditions precedent set forth
      in Section 12 are not then satisfied (provided that the delivery and
      receipt of such written notice shall not limit, affect or modify the
      Banks' obligations in respect of unpaid reimbursement obligations under
      Letters of Credit issued prior to the receipt of such notice, as specified
      in Section 5.1.4).

            5.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
      Application shall be completed to the satisfaction of the Issuing Bank. In
      the event that any provision of a Letter of Credit Application shall be
      inconsistent with any provision of this Credit Agreement, then the
      provision of this Credit Agreement shall, to the extent of any such
      inconsistency, govern.

            5.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit issued,
      extended or renewed hereunder shall, among other things, (i) provide for
      the payment of sight drafts for honor thereunder when presented in
      accordance with the terms thereof and when accompanied by the documents
      described therein, and (ii) have an expiry date no later than the date
      which is fourteen (14) days (or, if the Letter of Credit is confirmed by a
      confirmer or otherwise provides for one or more nominated persons,
      forty-five (45) days)


                                       21
   22
      prior to the Maturity Date. Without limiting the generality of clause (ii)
      of the immediately preceding sentence, each documentary Letter of Credit
      issued, extended or renewed hereunder shall have an expiry date not later
      than three hundred sixty (360) days after the date of its issuance,
      extension or renewal. Each Letter of Credit so issued, extended or renewed
      shall be subject to the Uniform Customs.

            5.1.4. REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank severally
      agrees that it shall be absolutely liable, without regard to the
      occurrence of any Default or Event of Default or any other condition
      precedent whatsoever, to the extent of such Bank's Commitment Percentage,
      to reimburse the Issuing Bank on demand for the amount of each draft paid
      by the Issuing Bank under each Letter of Credit to the extent that such
      amount is not reimbursed by the Borrower pursuant to Section 5.2 (such
      agreement for a Bank being called herein the "Letter of Credit
      Participation" of such Bank).

            5.1.5. PARTICIPATIONS OF BANKS. Each such payment made by a Bank
      shall be treated as the purchase by such Bank of a participating interest
      in the Borrower's Reimbursement Obligation under Section 5.2 in an amount
      equal to such payment. Each Bank shall share in accordance with its
      participating interest in any interest which accrues pursuant to Section
      5.2.

      5.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce the
Issuing Bank to issue, extend and renew each Letter of Credit and the Banks to
participate therein, the Borrower hereby agrees to reimburse or pay to the
Issuing Bank, for the account of the Issuing Bank or (as the case may be) the
Banks, with respect to each Letter of Credit issued, extended or renewed by the
Issuing Bank hereunder,

            (a) except as otherwise expressly provided in Sections 5.2(b) and
      (c), on each date that any draft presented under such Letter of Credit is
      honored by the Issuing Bank, or the Issuing Bank otherwise makes a payment
      with respect thereto, (i) the amount paid by the Issuing Bank under or
      with respect to such Letter of Credit, and (ii) the amount of any taxes,
      fees, charges or other costs and expenses whatsoever incurred by the
      Issuing Bank or any Bank in connection with any payment made by the
      Issuing Bank or any Bank under, or with respect to, such Letter of Credit,

            (b) upon the reduction (but not termination) of the Total Commitment
      to an amount less than the Maximum Drawing Amount, an amount equal to such
      difference, which amount shall be held by the Issuing Bank for the benefit
      of the Banks and the Issuing Bank as cash collateral for all Reimbursement
      Obligations, and

            (c) upon the termination of the Total Commitment, or the
      acceleration of the Reimbursement Obligations with respect to all Letters
      of Credit in accordance with Section 13, an amount equal to the then
      Maximum Drawing Amount, which amount shall be held by the Issuing Bank for
      the benefit of the Banks and the Issuing Bank as cash collateral for all
      Reimbursement Obligations.

Each such payment shall be made to the Issuing Bank at the Issuing Bank's Head
Office in immediately available funds. Interest on any and all amounts remaining
unpaid by the Borrower


                                       22
   23
under this Section 5.2 at any time from the date such amounts become due and
payable (whether as stated in this Section 5.2, by acceleration or otherwise)
until payment in full (whether before or after judgment) shall be payable to the
Issuing Bank on demand at the rate specified in Section 6.10 for overdue
principal on the Revolving Credit Loans.

      5.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or other
demand for payment shall be made under any Letter of Credit, the Issuing Bank
shall notify the Borrower of the date and amount of the draft presented or
demand for payment and of the date and time when it expects to pay such draft or
honor such demand for payment. If the Borrower fails to reimburse the Issuing
Bank as provided in Section 5.2 on or before the date that such draft is paid or
other payment is made by the Issuing Bank, the Issuing Bank may at any time
thereafter notify the Banks of the amount of any such Unpaid Reimbursement
Obligation. No later than 11:00 a.m. (California time) on the Business Day next
following the receipt of such notice, each Bank shall make available to the
Issuing Bank, at the Issuing Bank's Head Office, in immediately available funds,
such Bank's Commitment Percentage of such Unpaid Reimbursement Obligation,
together with an amount equal to the product of (i) the average, computed for
the period referred to in clause (iii) of this sentence, of the weighted average
interest rate paid by the Issuing Bank for federal funds acquired by the Issuing
Bank during each day included in such period, times (ii) the amount equal to
such Bank's Commitment Percentage of such Unpaid Reimbursement Obligation, times
(iii) a fraction, the numerator of which is the number of days that elapse from
and including the date the Issuing Bank paid the draft presented for honor or
otherwise made payment to the date on which such Bank's Commitment Percentage of
such Unpaid Reimbursement obligation shall become immediately available to the
Issuing Bank, and the denominator of which is 365. The responsibility of the
Issuing Bank to the Borrower and the Banks shall be only to determine that the
documents (including each draft) delivered under each Letter of Credit in
connection with such presentment shall be in conformity in all material respects
with such Letter of Credit.

      5.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this Section 5
shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Issuing Bank, any Bank or
any beneficiary of a Letter of Credit. The Borrower further agrees with the
Agent, the Issuing Bank and the Banks that the Issuing Bank and the Banks shall
not be responsible for, and the Borrower's Reimbursement Obligations under
Section 5.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrower, the beneficiary of any Letter of
Credit or any financing institution or other party to which any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrower against
the beneficiary of any Letter of Credit or any such transferee. The Issuing Bank
and the Banks shall not be liable for any error, omission, interruption or delay
in transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit. The Borrower agrees that
any action taken or omitted by the Issuing Bank or any Bank under or in
connection with each Letter of Credit and the related drafts and documents, if
done in good faith, shall be binding upon


                                       23
   24
the Borrower and shall not result in any liability on the part of the Issuing
Bank or any Bank to the Borrower.

      5.5. RELIANCE BY ISSUER. To the extent not inconsistent with Section 5.4,
the Issuing Bank shall be entitled to rely, and shall be fully protected in
relying upon, any Letter of Credit, draft, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel, independent accountants and
other experts selected by the Issuing Bank. The Issuing Bank shall be fully
justified in failing or refusing to take any action under this Credit Agreement
unless it shall first have received such advice or concurrence of the Majority
Banks as it reasonably deems appropriate or it shall first be indemnified to its
reasonable satisfaction by the Banks against any and all liability and expense
which may be incurred by it by reason of taking or continuing to take any such
action. The Issuing Bank shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement in accordance with a request of the
Majority Banks, and such request and any action taken or failure to act pursuant
thereto shall be binding upon the Banks and all future holders of the Revolving
Credit Notes, the Swingline Note or of a Letter of Credit Participation.

      5.6. LETTER OF CREDIT FEE. The Borrower shall, on the date of issuance or
any extension or renewal of any Letter of Credit and at such other time or times
as such charges are customarily made by the Issuing Bank, pay a fee (in each
case, a "Letter of Credit Fee") to the Issuing Bank (i) in respect of each
standby Letter of Credit a percentage, equal to the LIBOR Spread in effect on
the date of such issuance, of the face amount of such standby Letter of Credit
plus the Issuing Bank's issuance fee equal to one-eighth of one percent (1/8%)
per annum of the face amount of such standby Letter of Credit; and (ii) in
respect of each documentary Letter of Credit, equal to the Issuing Bank's
customary fees for such Letter of Credit at such time plus, in each case, the
Issuing Bank's customary amendment and other administrative processing fees,
such Letter of Credit Fee (but not such issuance, amendment or administrative
fees) to be for the accounts of the Banks in accordance with their respective
Commitment Percentages. Nothing herein shall (A) effect any change in the Letter
of Credit Fee paid in connection with any Letters of Credit issued pursuant to
the Original Credit Agreement that are outstanding on the Closing Date or (B)
require any adjustment to any Letter of Credit Fee as a result of any subsequent
change in the LIBOR Spread. If any existing Letters of Credit of the type
described in clause (A) above are extended or renewed, the Letter of Credit Fee
for such extension or renewal shall be calculated pursuant to this Section 5.6.

6. CERTAIN GENERAL PROVISIONS.

      6.1. AGENT'S FEE. The Borrower shall pay to the Agent an Agent's Fee in
accordance with the Fee Letter.

      6.2. FUNDS FOR PAYMENTS.

            6.2.1. PAYMENTS TO AGENT. All payments of principal, interest,
      Reimbursement Obligations, Commitment Fees, Letter of Credit Fees and any
      other amounts due hereunder or under any of the other Loan Documents shall
      be made to the


                                       24
   25
      Agent, for the respective accounts of the Banks and the Agent, at the
      Agent's Head Office or at such other location that the Agent may from time
      to time designate, in each case in immediately available funds.

            6.2.2. NO OFFSET, ETC. All payments by the Borrower hereunder or
      under any of the other Loan Documents shall be made without setoff or
      counterclaim and free and clear of, and without deduction for, any taxes,
      levies, imposts, duties, charges, fees, deductions, withholdings,
      compulsory loans, restrictions or conditions of any nature now or
      hereafter imposed or levied by any jurisdiction or any political
      subdivision thereof or taxing or other authority therein unless the
      Borrower is compelled by law to make such deduction or withholding. If any
      such obligation is imposed upon the Borrower with respect to any amount
      payable by it hereunder or under any of the other Loan Documents, the
      Borrower will pay to the Agent, for the account of the Banks or (as the
      case may be) the Agent, on the date on which such amount is due and
      payable hereunder or under such other Loan Document, such additional
      amount in Dollars as shall be necessary to enable the Banks or the Agent
      to receive the same net amount which the Banks or the Agent would have
      received on such due date had no such obligation been imposed upon the
      Borrower. The Borrower will deliver promptly to the Agent certificates or
      other valid vouchers for all taxes or other charges deducted from or paid
      with respect to payments made by the Borrower hereunder or under such
      other Loan Document.

            6.2.3. WITHHOLDING FORMS.

                  (a) Each Bank that is organized under the laws of a
            jurisdiction outside the United States hereby agrees that, if and to
            the extent it is legally able to do so and has not already done so,
            it shall, prior to the date of the first payment by the Borrower
            hereunder to be made to such Bank or for such Bank's account,
            deliver to the Borrower and the Agent, as applicable, such
            certificates, documents or other evidence, as and when required by
            the Code or Treasury Regulations issued pursuant thereto, including
            two (2) duly completed originals of Internal Revenue Service Form
            1001 or Form 4224 and any other certificate or statement of
            exemption required by Treasury Regulations, or any subsequent
            versions thereof or successors thereto, properly completed and duly
            executed by such Bank establishing that with respect to payments of
            principal, interest or fees hereunder it is (i) not subject to
            United States federal withholding tax under the Code because such
            payment is effectively connected with the conduct by such Bank of a
            trade or business in the United States or (ii) totally exempt from
            United States federal withholding taxes under a provision of an
            applicable tax treaty or, in the case of a Bank that is not a "bank"
            under Section 881(c) of the Code, a Form W-8 and a certificate
            stating that such Bank is not a "bank" within the meaning of the
            aforementioned Code Section .

                  (b) The Borrower shall not be required to pay any additional
            amounts to any Bank pursuant to this Section 6.2, if (i) the
            obligation to pay such additional amounts would not have arisen but
            for a failure by such Bank to deliver the forms contemplated by this
            Section 6.2.3; or (ii) the Bank is not eligible for complete


                                       25
   26
            exemption from United States federal withholding tax with respect to
            payments of interest, principal or fees under this Credit Agreement
            or under any of the other Loan Documents, other than by reason of
            any change, after the Initial Date, of any applicable law, treaty or
            regulations by any governmental authority or other agency charged
            with the interpretation or administration thereof. For purposes of
            this Section 6.2.3, the term "Initial Date" shall mean, with respect
            to any Bank which is a party hereto on the date hereof, the date
            hereof, and with respect to each assignee or transferee of any Bank,
            the date of the grant of the participation in, or transfer or
            assignment of an interest hereunder to, such assignee or transferee.

                  (c) If at any time any Bank makes any changes necessitating a
            new Form 4224 or Form 1001 or Form W-8, if applicable, it shall:

                        (i) with reasonable promptness deliver to the Borrower
            in replacement for, or in addition to, the forms previously
            delivered by it hereunder, two completed originals of Form 1001 or
            Form 4224 or Form W-8, as appropriate, in each case properly
            completed and duly executed by such Bank establishing that such Bank
            is on the date of delivery thereof entitled to receive payments of
            principal, interest and fees under this Credit Agreement free from
            withholding of United States Federal income tax;

                        (ii) before or promptly after the occurrence of any
            event (including the passing of time but excluding any event
            mentioned in (i) above) requiring a change in the most recent Form
            4224, Form 1001, or, as the case may be, Form W-8 previously
            delivered by such Bank and if the delivery of the same be lawful,
            deliver to the Borrower two completed originals of Form 4224, Form
            1001, or, as the case may be, Form W-8 in replacement for the forms
            previously delivered by the relevant Bank, in each case properly
            completed and duly executed; and

                        (iii) promptly upon the Borrower's reasonable request,
            deliver to the Borrower such other forms or similar documentation as
            may be required from time to time by any applicable law, treaty,
            rule or regulation in order to establish such Bank's tax status for
            withholding purposes.

                  (d) If the Borrower is required to pay any additional amounts
            to any Bank on account of required withholdings pursuant to this
            Section 6.2.3, then such Bank shall use its reasonable best efforts
            (consistent with legal and regulatory restrictions) to change the
            jurisdiction of its lending office so as to minimize any additional
            payments which may thereafter accrue; provided, that no Bank shall
            be required to change its lending office if such change would be, in
            the sole judgment of such Bank, otherwise disadvantageous to such
            Bank.

      6.3. COMPUTATIONS. All computations of interest on the Loans and of
Commitment Fees, Letter of Credit Fees or other fees shall, unless otherwise
expressly provided herein, be based on a 360-day year and paid for the actual
number of days elapsed. Except as otherwise provided in the definition of the
term "Interest Period" with respect to LIBOR Rate Loans,


                                       26
   27
whenever a payment hereunder or under any of the other Loan Documents becomes
due on a day that is not a Business Day, the due date for such payment shall be
extended to the next succeeding Business Day, and interest shall accrue during
such extension. The outstanding amount of the Loans as reflected on the
Revolving Credit Note Records and the Swingline Note Record from time to time
shall be considered correct and binding on the Borrower absent manifest error.

      6.4. INABILITY TO DETERMINE LIBOR RATE. In the event, prior to the
commencement of any Interest Period relating to any LIBOR Rate Loan, the Agent
shall determine or be notified by the Majority Banks that adequate and
reasonable methods do not exist for ascertaining the LIBOR Rate that would
otherwise determine the rate of interest to be applicable to any LIBOR Rate Loan
during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks. In such event (i) any Loan Request or
Conversion Request with respect to LIBOR Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (ii) each LIBOR
Rate Loan will automatically, on the last day of the then current Interest
Period relating thereto, become a Base Rate Loan, and (iii) the obligations of
the Banks to make LIBOR Rate Loans shall be suspended until the Agent or the
Majority Banks determines that the circumstances giving rise to such suspension
no longer exist, whereupon the Agent or, as the case may be, the Agent upon the
instruction of the Majority Banks, shall so notify the Borrower and the Banks.

      6.5. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain
LIBOR Rate Loans, such Bank shall forthwith give notice of such circumstances to
the Borrower and the other Banks and thereupon (i) the commitment of such Bank
to make LIBOR Rate Loans or convert Loans of another Type to LIBOR Rate Loans
shall forthwith be suspended and (ii) such Bank's Revolving Credit Loans then
outstanding as LIBOR Rate Loans, if any, shall be converted automatically to
Base Rate Loans on the last day of each Interest Period applicable to such LIBOR
Rate Loans or within such earlier period as may be required by law. The Borrower
hereby agrees promptly to pay the Agent for the account of such Bank, upon
demand by such Bank, any additional amounts necessary to compensate such Bank
for any costs incurred by such Bank in making any conversion in accordance with
this Section 6.5, including any interest or fees payable by such Bank to lenders
of funds obtained by it in order to make or maintain its LIBOR Rate Loans
hereunder.

      6.6. ADDITIONAL COSTS, ETC. If after the Closing Date any present or
future applicable law, which term, as used herein, includes statutes, rules and
regulations thereunder and interpretations thereof by any competent court or by
any governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Bank or the Agent by any central bank or other fiscal,
monetary or other authority (whether or not having the force of law), shall:

            (a) subject any Bank or the Agent to any tax, levy, impost, duty,
      charge, fee, deduction or withholding of any nature with respect to this
      Credit Agreement, the other


                                       27
   28
      Loan Documents, any Letters of Credit, such Bank's Commitment or the Loans
      (other than taxes based upon or measured by the income or profits of such
      Bank or the Agent), or

            (b) materially change the basis of taxation (except for changes in
      taxes on income or profits) of payments to any Bank of the principal of or
      the interest on any Loans or any other amounts payable to any Bank or the
      Agent under this Credit Agreement or any of the other Loan Documents, or

            (c) impose or increase or render applicable (other than to the
      extent specifically provided for elsewhere in this Credit Agreement) any
      special deposit, reserve, assessment, liquidity, capital adequacy or other
      similar requirements (whether or not having the force of law) against
      assets held by, or deposits in or for the account of, or loans by, or
      letters of credit issued by, or commitments of an office of any Bank, or

            (d) impose on any Bank or the Agent any other conditions or
      requirements with respect to this Credit Agreement, the other Loan
      Documents, any Letters of Credit, the Loans, such Bank's Commitment, or
      any class of loans, letters of credit or commitments of which any of the
      Loans, the Letters of Credit or such Bank's Commitment forms a part, and
      the result of any of the foregoing is

                        (i) to increase the cost to any Bank of making, funding,
            issuing, renewing, extending or maintaining any of the Loans or such
            Bank's Commitment or any Letter of Credit, or

                        (ii) to reduce the amount of principal, interest,
            Reimbursement Obligation or other amount payable to such Bank or the
            Agent hereunder on account of such Bank's Commitment, any Letter of
            Credit or any of the Loans, or

                        (iii) to require such Bank or the Agent to make any
            payment or to forgo any interest or Reimbursement Obligation or
            other sum payable hereunder, the amount of which payment or forgone
            interest or Reimbursement Obligation or other sum is calculated by
            reference to the gross amount of any sum receivable or deemed
            received by such Bank or the Agent from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand made by such Bank or
(as the case may be) the Agent at any time and from time to time and as often as
the occasion therefor may arise, pay to such Bank or the Agent such additional
amounts as would be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or forgone interest or Reimbursement
Obligation or other sum.

      6.7. CAPITAL ADEQUACY. If after the date hereof any Bank or the Agent
determines that (i) the adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by a court or governmental
authority with appropriate jurisdiction, or (ii) compliance by such Bank or the


                                       28
   29
Agent or any corporation controlling such Bank or the Agent with any law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) of any such entity regarding capital adequacy, has the
effect of reducing the return on such Bank's or the Agent's commitment with
respect to any Loans to a level below that which such Bank or the Agent could
have achieved but for such adoption, change or compliance (taking into
consideration such Bank's or the Agent's then existing policies with respect to
capital adequacy and assuming full utilization of such entity's capital) by any
amount deemed by such Bank or (as the case may be) the Agent to be material,
then such Bank or the Agent may notify the Borrower of such fact. To the extent
that the amount of such reduction in the return on capital is not reflected in
the Base Rate, the Borrower and such Bank shall thereafter attempt to negotiate
in good faith, within thirty (30) days after the day on which the Borrower
receives such notice, an adjustment payable hereunder that will adequately
compensate such Bank in light of these circumstances. If the Borrower and such
Bank are unable to agree to such adjustment within thirty (30) days after the
date on which the Borrower receives such notice, then commencing on the date of
such notice (but not earlier than the effective date of any such increased
capital requirement), the fees payable to such Bank hereunder shall increase by
an amount that will, in such Bank's reasonable determination, provide adequate
compensation. Each Bank shall allocate such cost increases among its customers
in good faith and on an equitable basis.

      6.8. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to Section 6.6 or Section 6.7 and a brief explanation of such
amounts which are due, submitted by any Bank or the Agent to the Borrower, shall
constitute prima facie evidence that such amounts are due and owing.

      6.9. INDEMNITY. The Borrower agrees to indemnify each Bank and to hold
each Bank harmless from and against any loss, cost or expense (including loss of
anticipated profits) that such Bank may sustain or incur as a consequence of (i)
default by the Borrower in payment of the principal amount of or any interest on
any LIBOR Rate Loans as and when due and payable, including any such loss or
expense arising from interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its LIBOR Rate Loans, (ii) default by the
Borrower in making a borrowing or conversion after the Borrower has given (or is
deemed to have given) a Loan Request or a Conversion Request relating thereto in
accordance with Section 2.6, Section 2.7 or 4.4 or (iii) the making of any
payment of a LIBOR Rate Loan or the making of any conversion of any such LIBOR
Rate Loan to a Base Rate Loan on a day that is not the last day of the
applicable Interest Period with respect thereto, including interest or fees
payable by such Bank to lenders of funds obtained by it in order to maintain any
such Loans.

      6.10. INTEREST AFTER DEFAULT. Overdue principal and (to the extent
permitted by applicable law) interest on the Loans and all other overdue amounts
payable hereunder or under any of the other Loan Documents shall bear interest
compounded monthly and payable on demand at a rate per annum equal to two
percent (2%) above the interest rate then otherwise applicable to such Loans
hereunder until such amount shall be paid in full (after as well as before
judgment).


                                       29

7. REPRESENTATIONS AND WARRANTIES.

      As of the date of this Agreement, the Closing Date, each Drawdown Date,
and the date of the issuance, extension, or renewal of any Letter of Credit, the
Borrower represents and warrants to each of the Banks and the Agent as follows:

      7.1. CORPORATE AUTHORITY.

            7.1.1. INCORPORATION: GOOD STANDING. Each of the Borrower and its

      now conducted and as presently contemplated, and (iii) is in good standing
      as a foreign corporation and is duly authorized to do business in each
      jurisdiction where such qualification is necessary except where a failure
      to be so qualified would not have a materially adverse effect on the
      business, assets or financial condition of the Borrower or such
      Subsidiary.

            7.1.2. AUTHORIZATION. The execution, delivery and performance of
      this Credit Agreement and the other Loan Documents to which the Borrower
      or any of its Subsidiaries is or is to become a party and the transactions
      contemplated hereby and thereby (i) are within the corporate authority of
      such Person, (ii) have been duly authorized by all necessary corporate
      proceedings, (iii) do not conflict with or result in any breach or
      contravention of any provision of law, statute, rule or regulation to

      license or permit applicable to such Person and (iv) do not conflict with
      any provision of the corporate charter or bylaws of', or any agreement or
      other instrument binding upon, the Borrower or any of its Subsidiaries.

            7.1.3. ENFORCEABILITY. The execution and delivery of this Credit
      Agreement and the other Loan Documents to which the Borrower or any of its
      Subsidiaries is or is to become a party will result in valid and legally
      binding obligations of such Person enforceable against it in accordance
      with the respective terms and provisions hereof and thereof, except as
      enforceability is limited by bankruptcy, insolvency, reorganization,
      moratorium or other laws relating to or affecting generally the
      enforcement of creditors' rights and except to the extent that
      availability of the remedy of specific performance or injunctive relief or
      other equitable remedy is subject to the discretion of the court before
      which any proceeding therefor may be brought.

      7.2. GOVERNMENTAL APPROVALS. The execution, delivery and performance by
the Borrower and any of its Subsidiaries of this Credit Agreement and the other
Loan Documents to which the Borrower or any of its Subsidiaries is or is to

require the approval or consent of' or filing with, any governmental agency or
authority other than those already obtained.

      7.3. FINANCIAL STATEMENTS. There has been furnished to each of the Banks a
      consolidated balance sheet of the Borrower and its Subsidiaries as at the
      Balance Sheet Date, and a consolidated statement of income of the Borrower
      and its Subsidiaries for the


                                       30
   31
      fiscal year then ended, certified by Coopers & Lybrand LLP as fairly
      presenting the consolidated financial position of the Borrower as at such
      date and for such period in all material respects in accordance with
      generally accepted accounting principles. Such balance sheet and statement
      of income have been prepared in accordance with generally accepted
      accounting principles and fairly present the financial condition of the
      Borrower as at the close of business on the date thereof and the results
      of operations for the fiscal year then ended. There are no contingent
      liabilities of the Borrower or any of its Subsidiaries as of such date
      involving material amounts, known to the officers of the Borrower, which
      were not disclosed in such balance sheet and the notes related thereto.

      7.4. NO MATERIAL CHANGES, ETC.; SOLVENCY.

            7.4.1. CHANGES. Since the Balance Sheet Date, there has occurred no
      materially adverse change in the financial condition or business of the
      Borrower and its Subsidiaries as shown on or reflected in the consolidated
      balance sheet of the Borrower and its Subsidiaries as at the Balance Sheet
      Date, or the consolidated statement of income for the fiscal year then
      ended, other than changes in the ordinary course of business that have not
      had any materially adverse effect, either individually or in the
      aggregate, on the business or financial condition of the Borrower or any
      of its Subsidiaries. Since the Balance Sheet Date, the Borrower has not
      made any Distribution.

            7.4.2. SOLVENCY. The Borrower and its Subsidiaries, taken as a
      whole, are, and will be after giving effect to the transactions
      contemplated by the Loan Documents, Solvent. As used herein, "Solvent"
      shall mean that the Borrower and its Subsidiaries, taken as a whole, (i)
      shall have a fair value and present fair saleable value of their assets
      that would exceed their stated liabilities and identified contingent
      liabilities, (ii) should be able to pay their debts as such debts become
      absolute and mature, and (iii) have and expect to continue to have, access
      to capital that would not be unreasonably small for the conduct of their
      business as now conducted and as proposed to be conducted following the
      Closing Date.

      7.5. FRANCHISES; PATENTS; COPYRIGHTS, ETC. Each of the Borrower and its
Subsidiaries possesses all franchises, patents, copyrights, trademarks, trade
names, licenses and permits, and rights in respect of the foregoing, adequate
for the conduct of its business substantially as now conducted without known
conflict with any rights of others.

      7.6. LITIGATION. Except as set forth in Schedule 7.6 hereto, there are no
actions, suits, proceedings or investigations of any kind pending or threatened
against the Borrower or any of its Subsidiaries before any court, tribunal or
administrative agency or board that, if adversely determined, either in any case
or in the aggregate, could reasonably be expected to materially adversely affect
the properties, assets, financial condition or business of the Borrower and its
Subsidiaries or materially impair the right of the Borrower and its
Subsidiaries, considered as a whole, to carry on business substantially as now
conducted by them, or result in any substantial liability not adequately covered
by insurance, or for which adequate reserves are not maintained on the
consolidated balance sheet of the Borrower and its Subsidiaries, or which
question the validity of this Credit Agreement or any of the other Loan
Documents, or any action taken or to be taken pursuant hereto or thereto.


                                       31
   32
      7.7. NO MATERIALLY ADVERSE CONTRACTS, ETC. Neither the Borrower nor any of
its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation that has or is
expected in the future to have a materially adverse effect on the business,
assets or financial condition of the Borrower or any of its Subsidiaries.
Neither the Borrower nor any of its Subsidiaries is a party to any contract or
agreement that has or is expected, in the reasonable judgment of the Borrower's
officers, to have a materially adverse effect on the business, assets or
financial condition of the Borrower or any of its Subsidiaries.

      7.8. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. Neither the Borrower
nor any of its Subsidiaries is in violation of any provision of its charter
documents, bylaws, or any agreement or instrument to which it may be subject or
by which it or any of its properties may be bound or any decree, order,
judgment, statute, license, rule or regulation, in any of the foregoing cases in
a manner that could result in the imposition of substantial penalties or
materially and adversely affect the financial condition, properties or business
of the Borrower or any of its Subsidiaries.

      7.9. TAX STATUS. The Borrower and its Subsidiaries (i) have made or filed
all federal and state income and all other tax returns, reports and declarations
required by any jurisdiction to which any of them is subject, (ii) have paid all
taxes and other governmental assessments and charges shown or determined to be
due on such returns, reports and declarations, except those being contested in
good faith and by appropriate proceedings and (iii) have set aside on their
books provisions reasonably adequate for the payment of all taxes for periods
subsequent to the periods to which such returns, reports or declarations apply.
There are no unpaid taxes in any material amount claimed to be due by the taxing
authority of any jurisdiction, and the officers of the Borrower know of no basis
for any such claim.

      7.10. NO EVENT OF DEFAULT. No Default or Event of Default has occurred and
is continuing.

      7.11. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. Neither the Borrower
nor any of its Subsidiaries is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is it an
"investment company", or an "affiliated company" or a "principal underwriter" of
an "investment company", as such terms are defined in the Investment Company Act
of 1940.

      7.12. ABSENCE OF FINANCING STATEMENTS, ETC. Except with respect to
Permitted Liens, there is no financing statement, security agreement, chattel
mortgage, real estate mortgage or other document filed or recorded with any
filing records, registry or other public office, that purports to cover, affect
or give notice of any present or possible future lien on, or security interest
in, any assets or property of the Borrower or any of its Subsidiaries or any
rights relating thereto.

      7.13. CERTAIN TRANSACTIONS. Except for arm's length transactions pursuant
to which the Borrower or any of its Subsidiaries makes payments in the ordinary
course of business upon terms no less favorable than the Borrower or such
Subsidiary could obtain from third parties, none of the officers, directors, or
employees of the Borrower or any of its Subsidiaries is


                                       32
   33
presently a party to any transaction with the Borrower or any of its
Subsidiaries (other than for services as employees, officers and directors),
including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer,
director or such employee or, to the knowledge of the Borrower, any corporation,
partnership, trust or other entity in which any officer, director, or any such
employee has a substantial interest or is an officer, director, trustee or
partner.

      7.14. EMPLOYEE BENEFIT PLANS.

            7.14.1. IN GENERAL. Each Employee Benefit Plan has been maintained
      and operated in compliance in all material respects with the provisions of
      ERISA and, to the extent applicable, the Code including, but not limited
      to, the provisions thereunder respecting prohibited transactions. The
      Borrower has heretofore delivered to the Agent the most recently completed
      annual report, Form 5500, with all required attachments, and actuarial
      statement required to be submitted under Section 103(d) of ERISA, with
      respect to each Guaranteed Pension Plan.

            7.14.2. TERMINABILITY OF WELFARE PLANS. Under each Employee Benefit
      Plan which is an employee welfare benefit plan within the meaning of
      Section 3(1) or Section 3(2)(B) of ERISA, no benefits are due unless the
      event giving rise to the benefit entitlement occurs prior to plan
      termination (except as required by Title I, Part 6 of ERISA). The Borrower
      or an ERISA Affiliate, as appropriate, may terminate each such Plan at any
      time (or at any time subsequent to the expiration of any applicable
      bargaining agreement) in the discretion of the Borrower or such ERISA
      Affiliate without liability to any Person.

            7.14.3. GUARANTEED PENSION PLANS. Each contribution required to be
      made to a Guaranteed Pension Plan, whether required to be made to avoid
      the incurrence of an accumulated funding deficiency, the notice or lien
      provisions of Section 302(f) of ERISA, or otherwise, has been timely made.
      No waiver of an accumulated funding deficiency or extension of
      amortization periods has been received with respect to any Guaranteed
      Pension Plan. No liability to the PBGC (other than required insurance
      premiums, all of which have been paid) has been incurred by the Borrower
      or any ERISA Affiliate with respect to any Guaranteed Pension Plan and
      there has not been any ERISA Reportable Event, or any other event or
      condition which presents a material risk of termination of any Guaranteed
      Pension Plan by the PBGC. Based on the latest valuation of each Guaranteed
      Pension Plan (which in each case occurred within twelve months prior to
      the date of this representation), and on the actuarial methods and
      assumptions employed for that valuation, the aggregate benefit liabilities
      of all such Guaranteed Pension Plans within the meaning of Section 4001 of
      ERISA did not exceed the aggregate value of the assets of all such
      Guaranteed Pension Plans, disregarding for this purpose the benefit
      liabilities and assets of any Guaranteed Pension Plan with assets in
      excess of benefit liabilities.

            7.14.4. MULTIEMPLOYER PLANS. Neither the Borrower nor any ERISA
      Affiliate has incurred any material liability (including secondary
      liability) to any Multiemployer Plan as a result of a complete or partial
      withdrawal from such Multiemployer Plan under Section 4201 of ERISA or as
      a result of a sale of assets described in Section 4204 of ERISA. Neither


                                       33
   34
      the Borrower nor any ERISA Affiliate has been notified that any
      Multiemployer Plan is in reorganization or insolvent under and within the
      meaning of Section 4241 or Section 4245 of ERISA or that any Multiemployer
      Plan intends to terminate or has been terminated under Section 4041A of
      ERISA.

      7.15. REGULATIONS U AND X. The proceeds of the Loans shall be used solely
for general corporate purposes including working capital and Capital
Expenditures of the Borrower. The Borrower will obtain Letters of Credit solely
for working capital and general corporate purposes. No portion of any Loan is to
be used, and no portion of any Letter of Credit is to be obtained, for the
purpose of purchasing or carrying any "margin security" or "margin stock" as
such terms are used in Regulations U and X of the Board of Governors of the
Federal Reserve System, 12 C.F.R. Parts 221 and 224.

      7.16. ENVIRONMENTAL COMPLIANCE. The Borrower, and each of its
Subsidiaries, has obtained all permits, licenses and other authorizations which
are required under all Environmental Laws, except to the extent failure to have
any such permit, license or authorization would not have a material adverse
effect on the business, assets or financial condition of the Borrower and its
Subsidiaries, taken as a whole. The Borrower, and each of its Subsidiaries, is
in compliance in all material respects with the terms and conditions of all such
permits, licenses and authorizations, and is also in compliance with all other
limitations, restrictions, conditions, standards, prohibitions, requirements,
obligations, schedules, and timetables contained in any applicable Environmental
Law, except to the extent failure to comply would not have a material adverse
effect on the business, assets or financial condition of the Borrower and its
Subsidiaries, taken as a whole.

      7.17. SUBSIDIARIES, ETC. The Borrower currently has no Subsidiaries except
HMT FSC Ltd., a Barbados West Indies Company. Except as set forth on Schedule
7.17 hereto the Borrower is not engaged in any joint venture or partnership with
any other Person.

      7.18. FISCAL YEAR. The Borrower and each of its Subsidiaries has a fiscal
year which is twelve (12) calendar months ending on March 31 of each year.

      7.19. NO AMENDMENTS TO CERTAIN DOCUMENTS. The Borrower has not amended any
of the Recapitalization Documents insofar as they relate to the character of the
Preferred Stock of the Borrower, has not amended any of the Subordinated Debt
Documents, and has not otherwise amended any of the Recapitalization Documents
in any way that could materially adversely affect the interest of the Banks.

      7.20. DISCLOSURE. No representation or warranty made by the Borrower in
this Credit Agreement or in any of the other Loan Documents or in any agreement,
instrument, document, certificate, statement or letter furnished to any of the
Bank Agents or any Bank by or on behalf of the Borrower as requested by the
Borrower in connection with any of the transactions contemplated by any of the
Loan Documents contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained
therein not misleading in light of the circumstances in which they are made.

8. AFFIRMATIVE COVENANTS OF THE BORROWER.

      The Borrower covenants and agrees that, so long as any Loan, Unpaid
Reimbursement Obligation, Letter of Credit or Note, or other amount in respect
of any of the foregoing, is outstanding or any Bank has any obligation to make
any Loans or the Issuing Bank has any obligation to issue, extend or renew any
Letters of Credit:

      8.1. PUNCTUAL PAYMENT. The Borrower will duly and punctually pay or cause
to be paid the principal and interest on the Loans, all Reimbursement
Obligations, the Letter of Credit Fees, the Commitment Fees, the Agent's fee and
all other amounts provided for in this Credit Agreement and the other Loan
Documents to which the Borrower or any of its Subsidiaries is a party, all in
accordance with the terms of this Credit Agreement and such other Loan

      the Borrower and its Subsidiaries on a consolidated basis if such event or

            (o) there shall occur the loss, suspension or revocation of, or

      whole; or


                                       49
   50

      comprised of some or all of Summit Ventures II, L.P., Summit Ventures IV,
      L.P., Summit Ventures II, L.P. and Summit Subordinated Debt Fund, L.P.,
      including for this purpose their affiliates and partners, and current
      management of the Borrower and employee stockholders of the Borrower shall

then, and in any such event, so long as the same may be continuing, the Agent
may, and upon the request of the Majority Banks shall, by notice in writing to
the Borrower declare all Obligations to be, and they shall thereupon forthwith
become, immediately due and payable without presentment, demand, protest or
other notice of any kind, all of which are hereby expressly waived by the
Borrower; provided that in the event of any Event of Default specified in
Section 13.1(g), 13.1(h) or 13.1(j), all such amounts shall become immediately
due and payable automatically and without any requirement of notice from the
Agent or any Bank.

      13.2. TERMINATION OF COMMITMENTS. If any one or more of the Events of
Default specified in Section 13.1(g), 13.1(h) or 13.1(j) shall occur, any unused
portion of the Commitments shall forthwith automatically terminate and each of
the Banks shall be relieved of all further obligations to make Loans to the
Borrower and the Issuing Bank shall be relieved of all further obligations to
issue, extend or renew Letters of Credit. If any other Event of Default shall
have occurred and be continuing, or if on any Drawdown Date or other date for
issuing, extending or renewing any Letter of Credit the conditions precedent to
the making of the Loans to be made on such Drawdown Date or (as the case may be)
to issuing, extending or renewing such Letter of Credit on such other date are
not satisfied, the Agent may and, upon the request of the Majority Banks, shall,
by notice to the Borrower, terminate the unused portion of the Total Commitment
hereunder, and upon such notice being given such unused portion of the Total
Commitment hereunder shall terminate immediately and each of the Banks shall be
relieved of all further obligations to make Loans and the Issuing Bank shall be
relieved of all further obligations to issue, extend or renew Letters of Credit.
No termination of the Total Commitment hereunder shall relieve the Borrower or
any of its Subsidiaries of any of the Obligations.

      13.3. REMEDIES. In case any one or more Events of Default shall have
occurred and be continuing, and whether or not the Banks shall have accelerated
the maturity of the Loans pursuant to Section 13.1, each Bank, if owed any
amount with respect to the Loans or the Reimbursement Obligations, may, with the
prior written consent of the Agent and the Majority Banks (including the Agent
in the calculation of "Majority Banks"), but not otherwise, proceed to protect
and enforce its rights by suit in equity, action at law or other appropriate
proceeding, whether for the specific performance of any covenant or agreement
contained in this Credit Agreement and the other Loan Documents or any
instrument pursuant to which the Obligations to such Bank are evidenced,
including as permitted by applicable law the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Bank. No remedy herein conferred upon any Bank
or the Agent or the holder of any Note or purchaser of any Letter of Credit
Participation is intended to be exclusive of any other remedy and each and every
remedy shall be cumulative and shall be in addition to every other remedy


                                       50
   51
given hereunder or now or hereafter existing at law or in equity or by statute
or any other provision of law.

14. SETOFF.

      During the continuance of any Event of Default, any deposits or other sums
credited by or due from any of the Banks to the Borrower and any securities or
other property of the Borrower in the possession of such Bank may be applied to
or set off by such Bank against the payment of Obligations and any and all other
liabilities, direct or indirect, of the Borrower to such Bank which are then due
and payable. Each of the Banks agrees with each other Bank that (i) if an amount
to be set off is to be applied to Indebtedness of the Borrower to such Bank,
other than Indebtedness evidenced by the Notes held by such Bank or constituting
Reimbursement Obligations owed to such Bank, such amount shall be applied
ratably to such other Indebtedness and to the Indebtedness evidenced by all such
Notes held by such Bank or constituting Reimbursement Obligations owed to such
Bank, and (ii) if such Bank shall receive from the Borrower, whether by
voluntary payment, exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Notes held by, or constituting
Reimbursement Obligations owed to, such Bank by proceedings against the Borrower
at law or in equity or by proof thereof in bankruptcy, reorganization,
liquidation, receivership or similar proceedings, or otherwise, and shall retain
and apply to the payment of the Note or Notes held by, or Reimbursement
Obligations owed to, such Bank any amount in excess of its ratable portion of
the payments received by all of the Banks with respect to the Notes held by, and
Reimbursement Obligations owed to, all of the Banks, such Bank will make such
disposition and arrangements with the other Banks with respect to such excess,
either by way of distribution, pro tanto assignment of claims, subrogation or
otherwise as shall result in each Bank receiving in respect of the Notes held by
it or Reimbursement Obligations owed it, its proportionate payment as
contemplated by this Credit Agreement; provided that if all or any part of such
excess payment is thereafter recovered from such Bank, such disposition and
arrangements shall be rescinded and the amount restored to the extent of such
recovery, but without interest.

15. THE AGENT.

      15.1. AUTHORIZATION.

            (a) Each of the Bank Agents and the Agent is authorized to take such
      action on behalf of each of the Banks and to exercise all such powers as

      documents delegated to each of the Bank Agents and the Agent, together
      with such powers as are reasonably incident thereto, provided that no
      duties or responsibilities not expressly assumed herein or therein shall
      be implied to have been assumed by either of the Bank Agents.

            (b) The relationship between each of the Bank Agents, the Agent and
      each of the Banks is that of an independent contractor. The use of the
      terms "Bank Agents" and "Agent" is for convenience only and is used to
      describe, as a form of convention, the independent contractual
      relationship between each of the Bank Agents, the Agent and each of the
      Banks. Nothing contained in this Credit Agreement nor the other Loan


                                       51
   52
      Documents shall be construed to create an agency, trust or other fiduciary
      relationship between each of the Bank Agents, the Agent and any of the
      Banks.

      15.2. EMPLOYEES AND AGENTS. Each of the Bank Agents and the Agent may
exercise its powers and execute its duties by or through employees or agents and
shall be entitled to take, and to rely on, advice of counsel concerning all
matters pertaining to its rights and duties under this Credit Agreement and the
other Loan Documents. Each of the Bank Agents and the Agent may utilize the
services of such Persons as such Bank Agent or Agent in its sole discretion may
reasonably determine, and all reasonable fees and expenses of any such Persons
shall be paid by the Borrower.

      15.3. NO LIABILITY. None of the Bank Agents, the Agent nor any of their
shareholders, directors, officers or employees nor any other Person assisting
them in their duties nor any agent or employee thereof' shall be liable for any
waiver, consent or approval given or any action taken, or omitted to be taken,
in good faith by it or them hereunder or under any of the other Loan Documents,
or in connection herewith or therewith, or be responsible for the consequences
of any oversight or error of judgment whatsoever, except that each of the Bank
Agents and the Agent or such other Person, as the case may be, may be liable for
losses exclusively due to its willful misconduct or gross negligence.

      15.4. NO REPRESENTATIONS. None of the Bank Agents or the Agent shall be
responsible for the execution or validity or enforceability of this Credit
Agreement, the Notes, the Letters of Credit, any of the other Loan Documents or
for the validity, enforceability or collectibility of any such amounts owing
with respect to the Notes, or for any recitals or statements, warranties or
representations made herein or in any of the other Loan Documents or in any
certificate or instrument hereafter furnished to it by or on behalf of the
Borrower or any of its Subsidiaries, or be bound to ascertain or inquire as to
the performance or observance of any of the terms, conditions, covenants or
agreements herein or to inspect any of the properties, books or records of the
Borrower or any of its Subsidiaries. None of the Bank Agents nor the Agent shall
be bound to ascertain whether any notice, consent, waiver or request delivered
to it by the Borrower or any holder of any of the Notes shall have been duly
authorized or is true, accurate and complete. None of the Bank Agents nor the
Agent has made nor does any of them now make any representations or warranties,
express or implied, nor does any of them assume any liability to the Banks, with
respect to the credit worthiness or financial conditions of the Borrower or any
of its Subsidiaries. Each Bank acknowledges that it has, independently and
without reliance upon any of the Bank Agents, the Agent or any other Bank, and
based upon such information and documents as it has deemed appropriate, made its
own credit analysis and decision to enter into this Credit Agreement and to
accept Borrower's Note and, in the case of the Issuing Bank, issue, renew and
extend Letters of Credit, and that it will continue to do so in connection with
making each Loan and issuance, renewal and extension of each Letter of Credit,
as applicable.

      15.5. PAYMENTS.

            15.5.1. PAYMENTS TO AGENT. A payment by the Borrower to the Agent
      hereunder or any of the other Loan Documents for the account of any Bank
      shall constitute a payment to such Bank. The Agent agrees promptly to
      distribute to each Bank such Bank's pro rata share of payments received by
      the Agent for the account of the


                                       52
   53
      Banks except as otherwise expressly provided herein or in any of the other
      Loan Documents.

            15.5.2. DISTRIBUTION BY AGENT. If in the opinion of the Agent the
      distribution of any amount received by it in such capacity hereunder,
      under the Notes or under any of the other Loan Documents might result in
      the incurrence by it of any liability, it may refrain from making such
      distribution until its right to make such distribution shall have been
      adjudicated by a court of competent jurisdiction. If a court of competent
      jurisdiction shall adjudge that any amount received from the Borrower and
      distributed by the Agent is to be repaid, each Person to whom any such
      distribution shall have been made shall either repay to the Agent its
      proportionate share of the amount so adjudged to be repaid or shall pay
      over the same in such manner and to such Persons as shall be determined by
      such court.

            15.5.3. DELINQUENT BANKS. Notwithstanding anything to the contrary
      contained in this Credit Agreement or any of the other Loan Documents, any
      Bank that fails (i) to make available to the Agent its pro rata share of
      any Loan or to purchase any Letter of Credit Participation or (ii) to
      comply with the provisions of Section 14 with respect to making
      dispositions and arrangements with the other Banks, where such Bank's
      share of any payment received, whether by setoff or otherwise, is in
      excess of its pro rata share of such payments due and payable to all of
      the Banks, in each case as, when and to the full extent required by the
      provisions of this Credit Agreement, shall be deemed delinquent (a
      "Delinquent Bank") and shall be deemed a Delinquent Bank until such time
      as such delinquency is remedied. A Delinquent Bank shall be deemed to have
      assigned any and all payments due to it from the Borrower, whether on
      account of outstanding Loans, Unpaid Reimbursement Obligations, interest,
      fees or otherwise, to the remaining nondelinquent Banks for application
      to, and reduction of, their respective pro rata shares of all outstanding
      Loans and Unpaid Reimbursement Obligations. The Delinquent Bank hereby
      authorizes the Agent to distribute such payments to the nondelinquent
      Banks in proportion to their respective pro rata shares of all outstanding
      Loans and Unpaid Reimbursement Obligations. A Delinquent Bank shall be
      deemed to have remedied in full a delinquency when and if', as a result of
      application of the assigned payments to all outstanding Loans and Unpaid
      Reimbursement Obligations of the nondelinquent Banks, the Banks'
      respective pro rata shares of all outstanding Loans and Unpaid
      Reimbursement Obligations have returned to those in effect immediately
      prior to such delinquency and without giving effect to the nonpayment
      causing such delinquency. Until such time as its delinquency is remedied,
      a Delinquent Bank shall have no right to vote with respect to any matters
      under or in respect of this Credit Agreement and shall not be entitled to
      receive its portion of any Commitment Fee paid in accordance with Section
      2.2 of this Credit Agreement.

      15.6. HOLDERS OF NOTES. The Agent may deem and treat the holder of any
Note or the purchaser of any Letter of Credit Participation as the absolute
owner or purchaser thereof for all purposes until it shall have been furnished
in writing with a different name by such payee or by a subsequent holder,
assignee or transferee.


                                       53
   54
      15.7. INDEMNITY. The Banks ratably (computed by reference to each Bank's
Total Percentage) agree hereby to indemnify and hold harmless the Bank Agents
and the Agent from and against any and all claims, actions and suits (whether
groundless or otherwise), losses, damages, costs, expenses (including any
expenses for which the Agent has not been reimbursed by the Borrower as required
by Section 16), and liabilities of every nature and character arising out of or
related to this Credit Agreement, the Notes, or any of the other Loan Documents
or the transactions contemplated or evidenced hereby or thereby, or the Bank
Agents' or the Agent's actions taken hereunder or thereunder, except to the
extent that any of the same shall be directly and exclusively caused by the Bank
Agents' or the Agent's willful misconduct or gross negligence.

      15.8. AGENT AS BANK. In its individual capacity, FNBB shall have the same
obligations and the same rights, powers and privileges in respect to its
Commitment, the Swingline Commitment and the Loans made by it, and as the holder
of any of the Notes and as the purchaser of any Letter of Credit Participations,
as it would have were it not also the Agent and a Co-Syndication Agent. In its
individual capacity, Paribas shall have the same obligations and the same
rights, powers and privileges in respect to its Commitment and the Loans made by
it, and as the holder of any of the Notes and as the purchaser of any Letter of
Credit Participations, as it would have were it not also a Co-Syndication Agent.
Each of the Banks acknowledges that each of the Bank Agents holds warrants for
the capital stock of the Borrower and is the holder of a Subordinated Note.

      15.9. RESIGNATION. Each Bank Agent may resign at any time by giving sixty
(60) days' prior written notice thereof to the Banks and the Borrower. Upon any
such resignation, the Majority Banks shall have the right to appoint a successor
Bank Agent in such capacity. Unless a Default or Event of Default shall have
occurred and be continuing, such successor Bank Agent shall be reasonably
acceptable to the Borrower; if a Default or Event of Default shall have occurred
and be continuing, the Borrower shall not be entitled to review the identity of
any proposed successor Bank Agent. If no successor Bank Agent shall have been so
appointed by the Majority Banks and other Bank Agents and shall have accepted
such appointment within thirty (30) days after the retiring Bank Agent's giving
of notice of resignation, then the retiring Bank Agent may, on behalf of the
Banks, appoint a successor Bank Agent in such capacity, which shall be a
financial institution having a rating of not less than A or its equivalent by
Standard & Poor's Ratings Group, a division of McGraw-Hill, Inc. Upon the
acceptance of any appointment as Bank Agent hereunder by a successor Bank Agent,
such successor Bank Agent shall thereupon succeed to and become vested with all
the rights, powers, privileges and duties of the retiring Bank Agent, and the
retiring Bank Agent shall be discharged from its duties and obligations
hereunder. After any retiring Bank Agent's resignation, the provisions of this
Credit Agreement and the other Loan Documents shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as Bank Agent.

      15.10. NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Bank hereby
agrees that, upon an officer of such Bank active in respect of the Borrower's
account learning of the existence of a Default or an Event of Default, it shall
promptly notify the Agent thereof. The Agent hereby agrees that upon receipt of
any notice under this Section 15.10 it shall promptly notify the other Banks of
the existence of such Default or Event of Default.


                                       54
   55
      15.11. DUTIES IN THE CASE OF ENFORCEMENT. In case one or more Events of
Default have occurred and shall be continuing, and whether or not acceleration
of the Obligations shall have occurred, the Agent shall, if (i) so requested by
the Majority Banks and (ii) the Banks have provided to the Agent such additional
indemnities and assurances against expenses and liabilities as the Agent may
reasonably request, proceed to exercise all or any such other legal and
equitable and other rights or remedies as the Bank may have in respect of such
Event of Default. The Majority Banks may direct the Agent in writing as to the
method and the extent of any such enforcement, the Banks hereby ratably
(computed by reference to each Bank's Total Percentage) agreeing to indemnify
and hold the Agent harmless from all liabilities incurred in respect of all
actions taken or omitted in accordance with such directions, provided that the
Agent need not comply with any such direction to the extent that the Agent
reasonably believes the Agent's compliance with such direction to be unlawful or
inadvisable.

      The Borrower agrees to pay (i) the reasonable costs of producing and
reproducing this Credit Agreement, the other Loan Documents and the other

litigation, or the preparation therefor, the Banks and the Bank Agents shall be
entitled to select their own counsel and, in addition to the foregoing
indemnity, the Borrower agrees to pay promptly the reasonable fees and expenses
of such counsel. If and to the extent that the obligations of the Borrower
under this Section 17 are unenforceable for any reason, the Borrower hereby
agrees to make the maximum contribution to the payment in satisfaction of such
obligations which is permissible under applicable law. The covenants contained

the Notes, in any of the other Loan Documents or in any documents or other

   57

Credit Agreement in an amount less than eleven percent (11%), such Bank Agent
agrees that, at the request of the Borrower and the Majority Banks, and provided
no Default or Event of Default shall have occurred and be continuing, such Bank
Agent shall resign as Bank Agent in accordance with Section 15.9 hereof. Upon

      and beneficial owner of the interest being assigned thereby free and clear
      of any adverse claim, the assigning Bank makes no representation or
      warranty, express or implied, and assumes no responsibility with respect
      to any statements, warranties or representations made in or in connection

      such Assignment and Acceptance;

            (d) such assignee will, independently and without reliance upon the
      assigning Bank, the Agent or any other Bank and based on such documents
      and information as it shall deem appropriate at the time, continue to make
      its own credit decisions in taking or not taking action under this Credit
      Agreement;

            (e) such assignee represents and warrants that it is an Eligible
      Assignee;

            (f) such assignee appoints and authorizes the Agent to take such

the recordation of the names and addresses of the Banks and the Commitment
Percentage of' and principal amount of the Revolving Credit Loans and Swingline
Loans owing to, and Letter of Credit Participations purchased by, the Banks from
time to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrower, the Agent and the Banks may treat each Person
whose name is recorded in the Register as a Bank hereunder for all purposes of
this Credit Agreement. The Register shall be available for inspection by the
Borrower and the Banks at any reasonable time and from time to time upon
reasonable prior notice. Upon each such recordation, the assigning Bank agrees
to pay or cause the assignee Bank to pay to the Agent a registration fee in the
sum of $3,500.

      19.4. NEW NOTES. Upon its receipt of an Assignment and Acceptance executed
by the parties to such assignment, together with each Note subject to such
assignment, the Agent shall (i) record the information contained therein in the
Register, and (ii) give prompt notice thereof to the Borrower and the Banks
(other than the assigning Bank). Within five (5) Business Days after receipt of
such notice, the Borrower, at its own expense, shall execute and deliver to the
Agent, in exchange for each surrendered Note, a new Note to the order of such
Eligible Assignee in an


                                       58
   59
amount equal to the amount assumed by such Eligible Assignee pursuant to such
Assignment and Acceptance and, if the assigning Bank has retained some portion
of its obligations hereunder, a new Note to the order of the assigning Bank in

of such new Notes and the legality, validity and binding effect thereof, in form
and substance satisfactory to the Banks, provided that the Borrower shall be
required to deliver such an opinion only at the request and the expense of the
Eligible Assignee. The surrendered Notes shall be marked "canceled" and returned
to the Borrower.

      19.5. PARTICIPATIONS. Each Bank may sell participations to one or more
banks or other Persons in all or a portion of such Bank's rights and obligations
under this Credit Agreement and the other Loan Documents; provided that (i) each
such participation shall be in an amount of not less than $5,000,000, (ii) any
such sale or participation shall not affect the rights and duties of the selling
Bank hereunder to the Borrower and (iii) the only rights granted to the
participant pursuant to such participation arrangements with respect to waivers,
amendments or modifications of the Loan Documents shall be the rights to approve
waivers, amendments or modifications that would reduce the principal of or the
interest rate on any Loans, extend the term or increase the amount of the
Commitment of such Bank as it relates to such participant, reduce the amount of
any Commitment Fees or Letter of Credit Fees to which such participant is
entitled or extend any regularly scheduled payment date for principal or
interest or fees.

      19.6. DISCLOSURE. The Borrower agrees that in addition to disclosures made
in accordance with standard and customary banking practices, any Bank may
disclose information obtained by such Bank pursuant to this Credit Agreement to
assignees or participants and potential assignees or participants hereunder;
provided that such assignees or participants or potential assignees or
participants shall agree (i) to treat in confidence such information unless such
information otherwise becomes public knowledge, (ii) not to disclose such
information to a third party, except to their legal counsel or as required by
law or legal process, and (iii) not to make use of such information for purposes
of transactions unrelated to such contemplated assignment or participation.

      19.7. ASSIGNEE OR PARTICIPANT AFFILIATED WITH THE BORROWER. If any
assignee Bank is an Affiliate of the Borrower, then any such assignee Bank shall
have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Agent pursuant to Section 13.1 or Section
13.2, and the determination of the Majority Banks shall for all purposes of this
Agreement and the other Loan Documents be made without regard to such assignee
Bank's interest in any of the Loans. If any Bank sells a participating interest
in any of the Loans or Reimbursement Obligations to a participant, and such
participant is the Borrower or an Affiliate of the Borrower, then such
transferor Bank shall promptly notify the Agent of the sale of such
participation. A transferor


                                       59
   60
Bank shall have no right to vote as a Bank hereunder or under any of the other
Loan Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or modifications to any of the Loan Documents or for
purposes of making requests to the Agent pursuant to Section 13.1 or Section
13.2 to the extent that such participation is beneficially owned by the Borrower
or any Affiliate of the Borrower, and the determination of the Majority Banks
shall for all purposes of this Agreement and the other Loan Documents be made
without regard to the interest of such transferor Bank in the Loans to the
extent of such participation.

      19.8. MISCELLANEOUS ASSIGNMENT PROVISIONS. Any assigning Bank shall retain
its rights to be indemnified pursuant to Section 16 or Section 17 with respect
to any claims or actions arising prior to the date of such assignment. If any
assignee Bank is not incorporated under the laws of the United States of America
or any state thereof, it shall, prior to the date on which any interest or fees
are payable hereunder or under any of the other Loan Documents for its account,
deliver to the Borrower and the Agent certification as to its exemption from
deduction or withholding of any United States federal income taxes. Anything

      The Borrower hereby waives its right to a jury trial with respect to any
action or claim arising out of any dispute in connection with this Credit

obligations hereunder or thereunder or the performance of which rights and
obligations. Except as prohibited by applicable law, the Borrower hereby waives

would not, in the event of litigation, seek to enforce the foregoing waivers and
(ii) acknowledges that the Agent, the Bank Agents and the Banks have been
induced to enter into this Credit Agreement, the other Loan Documents to which
it is a party and the Subordinated Debt Documents to which it is a party by,

modified except with the written consent of all of the Banks. No waiver shall
extend to or affect any obligation not expressly waived or impair any right
consequent thereon. No course of dealing or delay or omission on the part of the
Agent or any Bank in exercising any right shall operate as a waiver thereof or
otherwise be prejudicial thereto. No notice to or demand upon the Borrower shall
entitle the Borrower to other or further notice or demand in similar or other
circumstances.

27. SEVERABILITY.

      The provisions of this Credit Agreement and each of the other Loan
Documents are severable and if any one clause or provision hereof or thereof
shall be held invalid or unenforceable in whole or in part in any jurisdiction,

                                       62
   63
shall affect only such clause or provision, or part hereof or thereof, in such
jurisdiction, and shall not in any manner affect such clause or provision in any
other jurisdiction, or any other clause or provision of this Credit Agreement or
any of the other Loan Documents in any jurisdiction.

affiliates to take, reasonable precautions in accordance with its safe and sound
banking practice and its customary procedures, to maintain the confidentiality
of all non-public information relating to the Borrower or any Subsidiary
provided to such Bank Agent or Bank in connection with this Credit Agreement or
any other Loan Document, and none of the Bank Agents, the Banks, nor any of
their respective affiliates shall use any such information other than in
connection with or in enforcement of this Credit Agreement and the other Loan
Documents or in connection with other business now or hereafter existing or
contemplated with the Borrower or any Subsidiary, except to the extent such
information (i) was or becomes generally available to the public other than as a
result of disclosure by the Bank Agents or the Banks, or (ii) was or becomes
available on a non-confidential basis from a source other than the Borrower, so
long as such source is not bound by a confidentiality agreement with the
Borrower known to such Bank; provided, however, that the provisions of this
Section 28 shall not restrain the Bank AgeNTS or the Banks from divulging such
information (A) at the request or pursuant to any requirement of any
governmental authority to which a Bank Agent or Bank is subject or in connection
with an examination of such Bank Agent or Bank by any such authority; (B)
pursuant to subpoena or other court process; (C) when required to do so in
accordance with the provisions of any applicable legal requirement; (D) to the

by the provisions of this Section 28.
