            Amount and Terms of the Credit Facilities

Section 2.1 The Facility.

Each Lender agrees, severally but not jointly, on the terms and
subject to the conditions hereinafter set forth, to make Advances
to the Borrower from time to time during the period from the date
hereof to and including the Revolving Period Termination Date in
an aggregate amount not to exceed at any time outstanding that
Lender's Facility Amount. Each Borrowing shall be in an amount
equal to an integral multiple of $500,000 and not less than
$1,000,000 (or such greater amount as may be required pursuant to
Section 2.3(b) if any part of such Borrowing will constitute a
LIBO Rate Funding). Through the Revolving Period Termination
Date, the facility established hereby shall be a revolving
facility; within the limits of the Aggregate Facility Amount, the
Borrower may borrow, prepay pursuant to Section 2.7 and reborrow
under this Section 2.1. The Advances made by each Lender shall be
evidenced by a Note, payable to the order of that Lender in the
face principal amount of that Lender's Facility Amount.
Notwithstanding any other provision of this Agreement to the
contrary, no Borrowing shall be effected on any Principal Payment
Date.

Section 2.2 Procedure for Borrowings.

Each Borrowing shall occur on prior written request from the
Borrower to the Agent or telephonic request from any person
purporting to be authorized to request Borrowings on behalf of
the Borrower, which request shall specify the date of the
requested Borrowing and the amount thereof. Except as set forth
in Section 2.3(b), each such request by the Borrower shall be
made not less than one Business Day before the date of the
requested Borrowing.  Promptly upon receipt of such request, the
Agent shall advise each Lender of the proposed Borrowing. At or
before 2:00 p.m. on the date of the requested Borrowing, each
Lender shall provide the Agent at the principal office of the
Agent in Minneapolis, Minnesota with immediately available funds
covering such Lender's Percentage of such Borrowing.  The Agent
shall disburse the amount of the requested Borrowing by crediting
the same to the Borrower's demand deposit account maintained with
the Agent or in such other manner as the Agent and the Borrower
may from time to time agree; provided, however, that the Agent
shall have no obligation to disburse the requested Borrowing if
any condition set forth in Article III has not been satisfied on
the day of the requested Borrowing or if any Lender has failed to
fund its Percentage of the requested Borrowing. The Borrower
shall promptly confirm each telephonic request for a Borrowing by
executing and delivering an appropriate confirmation certificate
to the Agent. The Borrower shall be obligated to repay all
Advances notwithstanding the failure of the Agent to receive such
confirmation and notwithstanding the fact that the person
requesting same was not in fact authorized to do so.  Any request
for a Borrowing shall be deemed to be a representation that the
statements set forth in Section 3.2 are correct.

Section 2.3 Interest on Notes.

          (a)  Floating Rate Fundings. Unless the Borrower elects
     a LIBO Rate pursuant to this Section, the principal balance
     of the Notes shall bear interest at the Floating Rate.

          (b)  LIBO Rate Fundings. So long as no Default or Event
     of Default exists, the Borrower may request that a portion
     of any requested Borrowing constitute a LIBO Rate Funding,
     or may convert all or any part of any outstanding Floating
     Rate Funding into a LIBO Rate Funding, or may request that a
     LIBO Rate Funding be converted at the end of the applicable
     Interest Period to another LIBO Rate Funding, by giving
     notice to the Agent of such request or conversion not later
     than 10:30 a.m. on a Business Day which is at least three
     Business Days prior to the date of the requested Borrowing
     or conversion. Each such notice shall be effective upon
     receipt by the Agent, shall be in writing or by telephone or
     telecopy transmission, shall specify the date and amount of
     such Borrowing or conversion, and the Interest Period
     therefor. The Interest Period applicable to each LIBO Rate
     Funding shall begin on a Business Day, and the amount of
     each LIBO Rate Funding shall be an integral multiple of
     $1,000,000 and not less than $5,000,000. Subject to the
     terms and conditions hereof, the principal amount specified
     by the Borrower in the applicable request for a LIBO Rate
     Funding shall bear interest from and including the first day
     of the Interest Period specified therein to but not
     including the last day of such Interest Period, at the LIBO
     Rate applicable thereto, determined as set forth herein,
     (subject to fluctuations in the applicable Margin). Unless
     the Borrower requests a new LIBO Rate Funding in accordance
     with the procedures set forth above, or prepays the
     principal of an outstanding LIBO Rate Funding at the
     expiration of an Interest Period, the Lenders shall
     automatically and without request of the Borrower convert
     each LIBO Rate Funding to a Floating Rate Funding on the
     last day of the relevant Interest Period.

          (c)  Setting of LIBO Rates. The applicable LIBO Rate
     for each Interest Period shall be determined by the Agent
     between the opening of business and 12:00 noon on the second
     Business Day prior to the beginning of such Interest Period,
     whereupon notice thereof (which may be by telephone) shall
     be given by the Agent to the Borrower and each Lender. Each
     such determination of the applicable LIBO Rate shall be
     conclusive and binding upon the parties hereto, in the
     absence of demonstrable error. The Agent, upon written
     request of the Borrower, shall deliver to the Borrower a
     statement showing the computations used by the Agent in
     determining the applicable LIBO Rate hereunder.

          (d)  Limitations on LIBO Rate Fundings. In no event
     shall more than 6 LIBO Rate Fundings be outstanding at any
     one time. In no event may the Borrower request a LIBO Rate
     Funding if, after giving effect to such LIBO Rate Funding,
     the Borrower would be required to prepay a LIBO Rate Funding
     in order to make any regularly scheduled principal payment.

Section 2.4 Principal and Interest Payment Dates.

          (a)  Interest. Interest accruing on Floating Rate
     Fundings shall be due and payable on the last day of each
     calendar quarter. Interest on any LIBO Rate Funding shall be
     due and payable on the last day of the applicable Interest
     Period or, if such Interest Period is in excess of three
     months, on the last day of each three-month period during
     such Interest Period and on the last day of such Interest
     Period.

          (b)  Principal. The Borrower shall pay the principal
     balance of all Borrowings then outstanding in full on each
     Principal Payment Date.

Section 2.5 Level Status, Margins and Fee Rates.

     the basis of the Applicable Ratings established by the
     Rating Agencies, in accordance with the following table:

        A or      A- or     BBB+ or    BBB or   Less
S&P     better    better,   better,    better,  than BBB
                  but less  but less   but less
                  than A    than A-    than
                                       BBB+
        A2 or     A3 or     Baa1 or    Baa2 or  Less
Moody's better    better,   better,    better,  than
                  but less  but less   but less Baa2
                  than A2   than A3    than
                                       Baa1
Fitch   A or      A- or     BBB+ or    BBB or   Less

                  but less  but less   but less
                  than A    than A-    than
                                       BBB+

     If the Applicable Ratings established by the Rating Agencies
     differ such that they do not fall within a single column in
     the table set forth above, the Borrower's Level Status shall
     be determined as follows:

          (i)  If the Applicable Ratings applied by any two of
               the Rating Agencies are in the same column, the
               Borrower's Level Status shall be determined by
               that column.

          (ii) If the Applicable Ratings are each in separate
               columns, the highest and lowest columns shall be
               excluded, and the Borrower's Level Status shall be
               determined by the remaining Applicable Rating.

          (b)  In making the determinations under paragraph (a):

          (i)  If any of the Rating Agencies changes the meaning
               or designation for its Applicable Ratings
               referenced in paragraph (a), the criteria for
               Level Status in the table in paragraph (a) shall
               be adjusted in such manner as the Required Lenders
               may reasonably determine to correspond with the
               applicable rating designations used by the
               applicable Rating Agency in effect on the date
               hereof.

          (ii) If one of the Rating Agencies ceases to rate the
               Borrower's long-term unsecured debt such that only
               two of the Rating Agencies are providing such
               Applicable Ratings, the Borrower's Level Status
               shall be determined as follows:

               (A)  If the Applicable Ratings provided by both of
                    the remaining Rating Agencies are in the same
                    column, the Borrower's Level Status shall be
                    determined by that column.

               (B)  If the Applicable Ratings provided by the
                    remaining Rating Agencies are in adjacent
                    columns, the Borrower's Level Status shall be
                    based on the leftmost of the columns.

               (C)  If the Applicable Ratings provided by the
                    remaining Rating Agencies are separated by
                    one or more columns, the Borrower's Level
                    Status shall be based on the column to the
                    immediate right of the leftmost applicable
                    column.

               Notwithstanding the foregoing, if the Applicable
               Rating established by either of the remaining
               Rating Agencies is in the rightmost column above,
               the Borrower shall be deemed to be at Level Status
               V.

          (iii)If any two of the Rating Agencies ceases to
               establish its Applicable Rating, the Borrower
               shall be deemed to be at Level Status V.

          (c)  The Floating Rate Margin, LIBO Rate Margin,
     Facility Fee Rate and Utilization Fee Rate at any time shall
     be determined from time to time on the basis of the
     Borrower's Level Status, in accordance with the following
     table:

                   Level I   Level II   Level III Level IV   Level V

LIBO Rate Margin
                   0.295%    0.400%     0.500%    0.600%     0.750%
Facility Fee Rate
                   0.080%    0.100%     0.125%    0.150%     0.200%
Utilization Fee
Rate               0.100%    0.100%     0.125%    0.125%     0.200%

          (d)  Upon the occurrence of any Default or Event of
     Default, and so long as such Default or Event of Default
     continues without written waiver thereof by the Lenders, a
     default increment equal to 200 basis points (2.00%) shall be
     added to the Floating Rate Margin and LIBO Rate Margin.
     Inclusion of such default increment shall not be deemed a
     waiver or excuse of any such Default or Event of Default.

Section 2.6 Fees.

          (a)  Facility Fee. The Borrower shall pay to the Agent,
     for the ratable benefit of the Lenders, a facility fee

     condition in Article III has not been satisfied.

          (b)  Utilization Fee. The Borrower shall pay to the
     Agent, for the ratable benefit of the Lenders, a utilization
     fee determined at an annual rate equal to the then-
     applicable Utilization Fee Rate applied to the actual daily
     aggregate principal balance of the Notes on each day that
     such aggregate principal balance exceeds 50% of the
     Aggregate Facility Amount in effect on such day. The
     utilization fee shall be due and payable quarterly in
     arrears on the last day of each calendar quarter, and on the
     Maturity Date. The utilization fee shall accrue at all
     times, including at any time during which any condition in
     Article III has not been satisfied.

          (c)  Fee Letters. The Borrower shall pay to the Agent
     all fees required to be paid pursuant to any Fee Letters.

          (d)  Audit Fees. Upon the occurrence of an Event of
     Default or at any time thereafter until such Event of
     Default is cured, the Borrower shall pay to the Agent, on
     written demand, reasonable fees charged by the Agent in
     connection with any audits or inspections by the Agent of
     any collateral or the operations or businesses of the
     Borrower, together with actual out-of-pocket costs and
     expenses incurred in conducting any such audit or
     inspection. All such audits and inspections shall be for the
     sole benefit of the Agent and the Lenders.

Section 2.7 Prepayments.

          (a)  Voluntary Prepayments. The Borrower from time to
     time may voluntarily prepay the Notes in whole or in part;
     provided that (i) prepayment of any Lender's Note must be
     accompanied by pro rata prepayment of each other Lender's
     Note, (ii) any prepayment of the full amount of any Note
     shall include accrued interest thereon, (iii) partial
     prepayment of any Floating Rate Funding shall be in an
     aggregate amount not less than $1,000,000, (iv) partial
     prepayment of any LIBO Rate Funding shall be in an aggregate
     amount not less than $5,000,000, and (v) any prepayment of
     any LIBO Rate Funding shall be made only upon three Business
     Days' notice to the Agent.

          (b)  Application of Prepayments. So long as no Default
     or Event of Default has occurred and is continuing
     hereunder, all prepayments hereunder shall be applied in
     such order of application as the Borrower may direct in
     writing. In all other cases, all prepayments hereunder shall
     be applied in the following order:

          (i)  First, to the principal installments of the Notes
               (and, if such Notes are payable in installments,
               will be applied to such installments in inverse
               order of their maturities).

          (ii) Second, to accrued but unpaid interest on the
               Notes.

          (iii)Third, to any remaining Obligations, in such
               order as the Agent may in its sole discretion
               designate.

     Notwithstanding the foregoing, interest on any LIBO Rate
     Funding prepaid hereunder and any compensation due under
     Section 2.11 on account of prepayment of a LIBO Rate Funding
     shall be paid with the same priority as the related
     principal prepayment.

Section 2.8 Termination of Facility or Reduction of the Aggregate
Facility Amount.

The Borrower may at any time and from time to time upon three
Business Days' prior notice to the Agent permanently terminate
the Facility in whole or permanently reduce the Aggregate
Facility Amount in part, provided that (i) the Facility may not
be terminated while any Borrowings remain outstanding, (ii) each
partial reduction shall be in the amount of $5,000,000 or a
multiple thereof, (iii) no reduction shall reduce the Aggregate
Facility Amount to an amount less than the aggregate principal
balance of the Notes outstanding at the time, (iv) any partial
reduction of the Aggregate Facility Amount shall be applied pro
rata as to each Lender's Facility Amount in accordance with that
Lender's Percentage, and (v) each reduction in the Aggregate
Facility Amount shall constitute a corresponding reduction in the
Maximum Aggregate Facility Amount.

Section 2.9 Payments.

          (a)  Making of Payments. All payments of principal of
     and interest due under the Notes shall be made to the Agent
     at its principal office in Minneapolis, Minnesota, not later
     than 12:00 noon on the date due, in immediately available
     funds, and funds received after that hour shall be deemed to
     have been received by the Agent on the next following
     Business Day. The Borrower hereby authorizes the Agent to
     charge the Borrower's demand deposit account maintained with
     the Agent for the amount of any such payment on its due
     date, or (at the option of the Agent) to effect a Borrowing
     in such amount, all without receipt of any request for such
     charge or Borrowing, but the Lender's failure to so charge
     such account or effect such Borrowing shall in no way affect
     the obligation of the Borrower to make any such payment.

          (b)  Assumed Payments. Unless the Agent has been
     notified by a Lender or the Borrower prior to the date on
     which such Lender or the Borrower is scheduled to make
     payment to the Agent of (in the case of a Lender) the
     proceeds of an Advance to be made by it hereunder or (in the
     case of the Borrower) a payment to the Agent for the account
     of one or more of the Lenders hereunder (such payment by a
     Lender or the Borrower (as the case may be) being herein
     called a "Required Payment"), which notice shall be
     effective upon receipt, that it does not intend to make the
     Required Payment to the Agent, the Agent may assume that the
     Required Payment has been made and may (but shall not be
     required to), in reliance upon such assumption, make the
     amount thereof available to the intended recipient on such
     date and, if such Lender or the Borrower (as the case may
     be) has not in fact made the Required Payment to the Agent,
     the recipient of such payment shall, on demand, repay to the
     Agent the amount so made available together with interest
     thereon for each day during the period commencing on the
     date such amount was so made available by the Agent until
     the date the Agent recovers such amount at a rate (i) equal
     to the Federal Funds Rate for such day, in the case of a
     Required Payment owing by a Lender, or (ii) equal to the
     applicable rate of interest as provided in this Agreement,
     in the case of a Required Payment owing by the Borrower.

          (c)  Setoff. The Borrower agrees that each Lender shall
     have all rights of setoff and bankers' lien provided by
     applicable law, and in addition thereto, the Borrower agrees
     that if at any time any amount is due and owing by the
     Borrower under this Agreement to any Lender at a time when
     an Event of Default has occurred and is continuing
     hereunder, any Lender may apply any and all balances,
     credits, and deposits, accounts or moneys of the Borrower
     then or thereafter in the possession of that Lender
     (excluding, however, any trust or escrow accounts held by
     the Borrower for the benefit of any third party) to the
     payment thereof.

          (d)  Due Date Extension. If any payment of principal of
     or interest on any Floating Rate Funding or any fees payable
     hereunder falls due on a day which is not a Business Day,
     then such due date shall be extended to the next following
     Business Day, and (in the case of principal) additional
     interest shall accrue and be payable for the period of such
     extension.

          (e)  Application of Payments. Except as otherwise
     provided herein, so long as no Default or Event of Default
     has occurred and is continuing hereunder, each payment
     received from the Borrower shall be applied to such
     obligation as the Borrower shall specify by notice received
     by the Agent on or before the date of such payment, or in
     the absence of such notice, as the Required Lenders shall
     determine in their discretion. Except as otherwise provided
     herein, after the occurrence of a Default or Event of
     Default, the Lenders shall have the right to apply all
     payments received by the Lender from the Borrower as the
     Required Lenders may determine in their discretion. The
     Borrower agrees that the amount shown on the books and
     records of the Agent and the Lenders as being the principal
     balance of and interest on the Notes shall be conclusive
     absent demonstrable error.

Section 2.10 Increased Costs; Capital Adequacy; Funding
Exceptions.

          (a)  Increased Costs on LIBO Rate Fundings. If
     Regulation D of the Board of Governors of the Federal
     Reserve System or after the date of this Agreement the
     adoption of any applicable law, rule or regulation, or any
     change in any existing law, or any change in the
     interpretation or administration thereof by any governmental
     authority, central bank or comparable agency charged with
     the interpretation or administration thereof, or compliance
     by any Lender with any request or directive (whether or not
     having the force of law) of any such authority, central bank
     or comparable agency, shall:

          (i)  subject that Lender to or cause the withdrawal or
               termination of any exemption previously granted to
               that Lender with respect to, any tax, duty or
               other charge with respect to its LIBO Rate
               Fundings or its obligation to make LIBO Rate
               Fundings, or shall change the basis of taxation of
               payments to that Lender of the principal of or
               interest under this Agreement in respect of its
               LIBO Rate Fundings or its obligation to make LIBO
               Rate Fundings (except for changes in the rate of
               tax on the overall net income of that Lender
               imposed by the jurisdictions in which that
               Lender's principal executive office is located);
               or

          (ii) impose, modify or deem applicable any reserve
               (including, without limitation, any reserve
               imposed by the Board of Governors of the Federal
               Reserve System, but excluding any reserve included
               in the determination of interest rates pursuant to
               Section 2.3), special deposit or similar
               requirement against assets of, deposits with or
               for the account of, or credit extended by, that
               Lender; or

          (iii)impose on that Lender any other condition
               affecting its making, maintaining or funding of
               its LIBO Rate Fundings or its obligation to make
               LIBO Rate Fundings;

     and the result of any of the foregoing is to increase the
     cost to that Lender of making or maintaining any LIBO Rate
     Funding, or to reduce the amount of any sum received or
     receivable by that Lender under this Agreement or under its
     Notes with respect to a LIBO Rate Funding, then that Lender
     will notify the Borrower of such increased cost and within
     fifteen (15) days after demand by that Lender (which demand
     shall be accompanied by a statement setting forth the basis
     of such demand and representing that that Lender has made
     similar demand on one or more other commercial borrowers
     with revolving or term loans in excess of $1,000,000) the
     Borrower shall pay to that Lender such additional amount or
     amounts as will compensate that Lender for such increased
     cost or such reduction; provided, however, that no such
     increased cost or such reduction shall be payable by the
     Borrower for any period longer than ninety (90) days prior
     to the date on which notice thereof is delivered to the
     Borrower. Each Lender will promptly notify the Borrower of
     any event of which it has knowledge, occurring after the
     date hereof, which will entitle that Lender to compensation
     pursuant to this Section 2.10. If the Borrower receives
     notice from any Lender of any event which will entitle that
     Lender to compensation pursuant to this Section 2.10, the
     Borrower may prepay any then outstanding LIBO Rate Fundings
     or notify that Lender that any pending request for a LIBO
     Rate Funding shall be deemed to be a request for a Floating
     Rate Funding, in each case subject to the provisions of
     Section 2.11.

          (b)  Capital Adequacy. If any Lender determines at any
     time that its Return has been reduced as a result of any
     Capital Adequacy Rule Change, that Lender may require the
     Borrower to pay it the amount necessary to restore that
     Lender's Return to what it would have been had there been no
     Capital Adequacy Rule Change. For purposes of this 2.10, the
     following definitions shall apply:

          (i)  "Return", for any calendar quarter or shorter
               period, means the percentage determined by
               dividing (A) the sum of interest and ongoing fees
               earned by a Lender under this Agreement during
               such period by (B) the average capital that Lender
               is required to maintain during such period as a
               result of its being a party to this Agreement, as
               determined by that Lender based upon its total
               capital requirements and a reasonable attribution
               formula that takes account of the Capital Adequacy
               Rules then in effect. Return may be calculated for
               each calendar quarter and for the shorter period
               between the end of a calendar quarter and the date
               of termination in whole of this Agreement.

          (ii) "Capital Adequacy Rule" means any law, rule,
               regulation or guideline regarding capital adequacy
               that applies to any Lender, or the interpretation
               thereof by any governmental or regulatory
               authority. Capital Adequacy Rules include rules
               requiring financial institutions to maintain total
               capital in amounts based upon percentages of
               outstanding loans, binding loan commitments and
               letters of credit.

          (iii)"Capital Adequacy Rule Change" means any
               change in any Capital Adequacy Rule occurring
               after the date of this Agreement, but does not
               include any changes in applicable requirements
               that at the date hereof are scheduled to take
               place under the existing Capital Adequacy Rules or
               any increases in the capital that any Lender is
               required to maintain to the extent that the
               increases are required due to a regulatory
               authority's assessment of that Lender's financial
               condition.

          (iv) "Lender" includes (but is not limited to) the
               Agent, the Lenders, as defined elsewhere in this
               Agreement, and any assignee of any interest of any
               Lender hereunder and any participant in the loans
               made hereunder.

     The initial notice sent by a Lender shall be sent as
     promptly as practicable after that Lender learns that its
     Return has been reduced, shall include a demand for payment
     of the amount necessary to restore that Lender's Return for
     the quarter in which the notice is sent, shall state in
     reasonable detail the cause for the reduction in that
     Lender's Return and that Lender's calculation of the amount
     of such reduction, and shall include that Lender's
     representation that it has made similar demand on one or
     more other commercial borrowers with revolving or term loans
     in excess of $1,000,000. Thereafter, that Lender may send a
     new notice during each calendar quarter setting forth the
     calculation of the reduced Return for that quarter and
     including a demand for payment of the amount necessary to
     restore that Lender's Return for that quarter. A Lender's
     calculation in any such notice shall be conclusive and
     binding absent demonstrable error.

          (c)  Basis for Determining Interest Rate Inadequate or
     Unfair. If with respect to any Interest Period:

          (i)  any Lender determines that deposits in U.S.
               dollars (in the applicable amounts) are not being
               offered in the London interbank eurodollar market
               for such Interest Period; or

          (ii) any Lender otherwise determines that by reason of
               circumstances affecting the London interbank
               eurodollar market adequate and reasonable means do
               not exist for ascertaining the applicable LIBO
               Rate; or

          (iii)any Lender determines that the LIBO Rate as
               determined by the Agent will not adequately and
               fairly reflect the cost to that Lender of
               maintaining or funding a LIBO Rate Funding for
               such Interest Period, or that the making or
               funding of LIBO Rate Fundings has become
               impracticable as a result of an event occurring
               after the date of this Agreement which in the
               opinion of that Lender materially affects such
               LIBO Rate Fundings;

     then that Lender shall promptly notify the Borrower and (A)
     upon the occurrence of any event described in the foregoing
     clause (i) the Borrower shall enter into good faith
     negotiations with that Lender in order to determine an
     alternate method to determine the LIBO Rate for that Lender,
     and during the pendency of such negotiations with that
     Lender, the Lenders shall be under no obligation to make any
     new LIBO Rate Fundings, and (B) upon the occurrence of any
     event described in the foregoing clauses (ii) or (iii), for
     so long as such circumstances shall continue, the Lenders
     shall be under no obligation to make any new LIBO Rate
     Fundings.

          (d)  Illegality. If any change in (including the
     adoption of any new) applicable laws or regulations, or any
     change in the interpretation of applicable laws or
     regulations by any governmental authority, central bank,
     comparable agency or any other regulatory body charged with
     the interpretation, implementation or administration
     thereof, or compliance by any Lender with any request or
     directive (whether or not having the force of law) of any
     such authority, central bank, comparable agency or other
     regulatory body, should make it or, in the good faith
     judgment of that Lender, shall raise a substantial question
     as to whether it is unlawful for that Lender to make,
     maintain or fund LIBO Rate Fundings, then (i) that Lender
     shall promptly notify the Borrower and the Agent, (ii) the
     obligation of the Lenders to make, maintain or convert into
     LIBO Rate Fundings shall, upon the effectiveness of such
     event, be suspended for the duration of such unlawfulness,
     and (iii) for the duration of such unlawfulness, any notice
     by the Borrower requesting the Lenders to make or convert
     into LIBO Rate Fundings shall be construed as a request to
     make or to continue making Floating Rate Fundings.

Section 2.11 Funding Losses.

Upon demand by any Lender (which demand shall be accompanied by a
statement setting forth the basis for the calculations of the
amount being claimed), the Borrower shall indemnify that Lender
against any loss or expense which that Lender may have sustained
or incurred (including, without limitation, any net loss or
expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by that Lender to fund or
maintain LIBO Rate Fundings) or which that Lender may be deemed
to have sustained or incurred, as reasonably determined by that
Lender, (i) as a consequence of any failure by the Borrower to
make any payment when due of any amount due hereunder in
connection with any LIBO Rate Fundings, (ii) due to any failure
of the Borrower to borrow or convert any LIBO Rate Fundings on a
date specified therefor in a notice thereof or (iii) due to any
payment or prepayment of any LIBO Rate Funding on a date other
than the last day of the applicable Interest Period for such LIBO
Rate Funding. For this purpose, all notices under Section 2.3(b)
shall be deemed to be irrevocable.

Section 2.12 Discretion of Lenders as to Manner of Funding.

Notwithstanding any provision of this Agreement to the contrary,
each Lender shall be entitled to fund and maintain all or any
part of its LIBO Rate Fundings in any manner it deems fit, it
being understood, however, that for the purposes of this
Agreement (specifically including, without limitation, Section
2.11 hereof) all determinations hereunder shall be made as if
that Lender had actually funded and maintained each LIBO Rate
Funding during each Interest Period for such LIBO Rate Funding
through the purchase of deposits having a maturity corresponding
to such Interest Period and bearing an interest rate equal to the
appropriate LIBO Rate for such Interest Period.

Section 2.13 Conclusiveness of Statements; Survival of
Provisions.

Determinations and statements of any Lender pursuant to Sections
2.10 and 2.11 shall be conclusive absent demonstrable error.
Without limiting the generality of the foregoing, the Borrower
shall have no right to review any records of any Lender or its
other customers to determine the accuracy of any statement by
that Lender under Section 2.10(a) or 2.10(b) regarding that
Lender's demands upon other customers of that Lender.  Each
Lender may use reasonable averaging and attribution methods in
determining compensation pursuant to such Sections 2.10 and 2.11
and the provisions of Sections 2.10 and 2.11 shall survive
termination of this Agreement.

Section 2.14 Computation of Interest and Fees.

All interest determined at the Floating Rate will be calculated
based on the actual days elapsed in a year of 365 or 366 days, as
the case may be. All interest determined at the LIBO Rate and all
fees hereunder shall be computed on the basis of actual number of
days elapsed in a year of 360 days.

Section 2.15 Purpose of Borrowings.

The proceeds of the initial Borrowing hereunder shall be used to
pay in full all obligations of the Borrower outstanding under the
Existing Credit Facility, if any. The proceeds of each other
Borrowing (including the initial Borrowing, if no obligations
described in the preceding sentence are outstanding on the date
thereof) shall be used solely (i) to pay the Borrower's
obligations under (A) its commercial paper program, (B) other
short-term credit facilities, and (C) maturing long-term
obligations, and (ii) for the general corporate purposes of the
Borrower in the ordinary course of business.

Section 2.16 Increase of Aggregate Facility Amount.

          (a)  So long as no Default or Event of Default has
     occurred and is continuing, the Borrower may, upon at least
     25 days' written notice to the Agent, propose to increase
     the Aggregate Facility Amount by a multiple of $5,000,000
     that is not less than $15,000,000 and not greater than
     $25,000,000 (the amount of any such increase, the
     "Additional Facility Amount"). In no event shall any such
     increase cause the Aggregate Facility Amount to exceed the
     Maximum Aggregate Facility Amount. The Agent will promptly
     provide a copy of any such notice to each Lender. Each
     Lender may, not more than 20 days following such notice,
     elect by written notice to the Borrower and the Agent to
     increase its Facility Amount by a principal amount equal to
     its Percentage of the Additional Facility Amount.  No Lender
     (or any successor thereto) shall have any obligation to
     increase its Facility Amount or its other obligations under
     this Agreement and the other Loan Documents, and any
     decision by a Lender to increase its Facility Amount shall
     be made in its sole discretion independently from any other
     Lender.

          (b)  If any Lender elects not to increase its Facility
     Amount pursuant to paragraph (a), the Borrower may designate
     another Eligible Lender (which may be, but need not be, one
     or more of the existing Lenders) that will, in the case of
     any such Person that is an existing Lender, increase its
     Facility Amount and in the case of any other such Person (an
     "Incremental Lender"), become a party to this Agreement;
     provided, however, that any Incremental Lender must in all
     respects be acceptable to the Agent, which acceptance will
     not be unreasonably withheld. The sum of the increases in
     the Facility Amounts of the existing Lenders pursuant to
     this paragraph (b) plus the Facility Amounts of the
     Incremental Lenders shall not in the aggregate exceed the
     unsubscribed amount of the Maximum Aggregate Facility
     Amount.

          (c)  An increase in the Aggregate Facility Amount
     pursuant to this Section 2.16 shall become effective upon
     the receipt by the Agent of an agreement in form and
     substance satisfactory to the Agent signed by the Borrower,
     by each Incremental Lender and by each other Lender whose
     Aggregate Facility Amount is to be increased, setting forth
     the new Facility Amounts of such Lenders and setting forth
     the agreement of each Incremental Lender to become a party
     to this Agreement and to be bound by all the terms and
     provisions hereof (a "Facility Increase Agreement"),
     together with a replacement or additional Note, as
     applicable, evidencing the new Facility Amount of each
     affected Lender, duly executed and delivered by the Borrower
     and such evidence of appropriate corporate authorization on
     the part of the Borrower with respect to the increase in the
     Aggregate Facility Amount and such opinions of counsel for
     the Borrower with respect to the increase in the Aggregate
     Facility Amount as the Agent may reasonably request.

          (d)  Upon the acceptance of the Facility Increase
     Agreement by the Agent, the Aggregate Facility Amount shall
     automatically be increased by the amount of the Facility
     Amounts added through such Facility Increase Agreement.

          (e)  Upon any increase in the Aggregate Facility Amount
     pursuant to this Section 2.16 that is not pro rata among all
     Lenders, within 5 Business Days, the Borrower shall prepay
     all Borrowings hereunder in their entirety and, to the
     extent the Borrower elects to do so and subject to the
     conditions specified in Section 3.2, the Borrower shall
     effect new Borrowings from the Lenders in proportion to
     their respective Facility Amounts after giving effect to
     such increase.

                           ARTICLE III
                      Conditions Precedent

     Borrower.

          (b)  A certificate of the secretary of the Borrower
     (i) certifying that the execution, delivery and performance
     of the Loan Documents and other documents contemplated

     submitting the signatures of the officers named in such
     further certificate.

          (c)  Certificates of good standing of the Borrower,

such Borrowing:

          (a)  the representations and warranties contained in
     Article IV (other than Section 4.6) are correct on and as of
     the date of such Borrowing as though made on and as of such
     date, except to the extent that such representations and
     warranties relate solely to an earlier date;

          (b)  the Borrower has delivered to the Agent an opinion

     result from such Borrowing, which constitutes a Default or
     an Event of Default.

                           ARTICLE IV
                 Representations and Warranties

The Borrower represents and warrants to the Lenders as follows:

Section 4.1 Existence and Power.

The Borrower is a corporation duly incorporated, validly existing
and in good standing under the laws of Delaware, and is duly
licensed or qualified to transact business in all jurisdictions
where the character of the property owned or leased or the nature
of the business transacted by it makes such licensing or
qualification necessary, except where the failure to be so
licensed or qualified (i) will not permanently preclude the
Borrower from maintaining any material action in any such
jurisdiction even though such action arose in whole or in part
during the period of such failure, and (ii) will not result in
any other Material Adverse Effect. The Borrower has all requisite
power and authority, corporate or otherwise, to conduct its
business, to own its properties and to execute and deliver, and
to perform all of its obligations under, the Loan Documents.

Section 4.2 Authorization of Borrowing; No Conflict as to Law or
Agreements.

The execution, delivery and performance by the Borrower of the
Loan Documents and the borrowings from time to time hereunder
have been duly authorized by all necessary corporate action and
by all necessary public utilities commissions and any other
regulatory bodies having jurisdiction over the Borrower (except
as noted in Schedule 4.2 to the Agreement with respect to
Borrowings made after December 31, 2006), and do not and will not
(i) require any consent or approval of the stockholders of the
Borrower, or any authorization, consent or approval by any
governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, other than Authorizing
Orders set forth in Schedule 4.2 that (except as noted therein
with respect to Borrowings made after December 31, 2006) have
been obtained and copies of which have been delivered to the
Agent pursuant to Section 3.1, (ii) violate any provision of any
law, rule or regulation (including, without limitation,
Regulation X of the Board of Governors of the Federal Reserve
System) or of any order, writ, injunction or decree presently in
effect having applicability to the Borrower or of the articles of
incorporation or bylaws of the Borrower, (iii) result in a breach
of or constitute a default under any indenture or loan or credit
agreement or any other agreement, lease or instrument to which
the Borrower is a party or by which it or its properties may be
bound or affected, or (iv) result in, or require, the creation or
imposition of any Lien or other charge or encumbrance of any
nature (other than those in favor of the Agent to secure one or
more of the Obligations) upon or with respect to any of the
properties now owned or hereafter acquired by the Borrower.

Section 4.3 Legal Agreements.

This Agreement and the other Loan Documents constitute, the
legal, valid and binding obligations of the Borrower enforceable
against the Borrower in accordance with their respective terms,
except to the extent that such enforcement may be limited by
bankruptcy, insolvency or similar laws affecting the enforcement
of creditors' rights generally or by general equitable
principles.

Section 4.4 Subsidiaries.

Schedule 4.4 hereto is a complete and correct list of all present
Subsidiaries and of the percentage of the ownership of the
Borrower or any other Subsidiary in each case as of the date of
this Agreement. Except as otherwise indicated in that Schedule,
all shares of each Subsidiary owned by the Borrower or by any
such other Subsidiary are validly issued and fully paid and
nonassessable.

Section 4.5 Financial Condition.

The Borrower has heretofore furnished to the Lenders its audited
consolidated financial statement as of December 31, 2004, and its
unaudited interim financial statement as of March 31, 2005. Those
financial statements fairly present the financial condition of
the Borrower and its Subsidiaries on the dates thereof and the
results of their operations and cash flows for the periods then
ended, and were prepared in accordance with GAAP, except as
expressly noted therein.

Section 4.6 Adverse Change.

There has been no material adverse change in the business,
properties or condition (financial or otherwise) of the Borrower
since the date of the latest financial statement referred to in
Section 4.5.

Section 4.7 Litigation.

Except as set forth in the Borrower's Annual Report on Form 10-K
for the year ended December 31, 2004, or in any document
subsequently filed pursuant to Section 13, 14 or 15(d) of the
Exchange Act, there are no actions, suits or proceedings pending
or, to the knowledge of the Borrower, threatened against or
affecting the Borrower or the properties of the Borrower, before
any court or governmental department, commission, board, bureau,
agency or instrumentality, domestic or foreign, which, if
determined adversely to the Borrower, would have a Material
Adverse Effect.

Section 4.8 Environmental Matters.

The Borrower conducts in the ordinary course of business a review
of the effect of existing Environmental Laws and existing
Environmental Claims on its business, operations and properties
and, as a result thereof, the Borrower has reasonably concluded
that such Environmental Laws and Environmental Claims could not,
individually or in the aggregate, reasonably be expected to have
a Material Adverse Effect, exclusive of Environmental Claims as
set forth in the Borrower's Annual Report on Form 10-K for the
year ended December 31, 2004, or in any document subsequently
filed pursuant to Section 13, 14 or 15(d) of the Exchange Act.

Section 4.9 Regulation U.

The Borrower is not engaged in the business of extending credit
for the purpose of purchasing or carrying margin stock (within
the meaning of Regulation U of the Board of Governors of the
Federal Reserve System), and no part of the proceeds of any
Borrowing will be used to purchase or carry any margin stock or
to extend credit to others for the purpose of purchasing or
carrying any margin stock.

Section 4.10 Taxes.

The Borrower has filed all federal and other tax returns and
reports required to be filed, and has paid all federal and other
taxes, assessments, fees and other governmental charges levied or
imposed upon it or its properties, income or assets otherwise due
and payable, except those which are being contested in good faith
by appropriate proceedings and for which adequate reserves have
been provided in accordance with GAAP and except those the
failure to file or pay which would not have a Material Adverse
Effect. There is no proposed tax assessment against the Borrower
that would, if made, have a Material Adverse Effect.

Section 4.11 Titles and Liens.

To the Borrower's knowledge, without having undertaken any search
of real property records for this purpose, the Borrower has good
and sufficient title to, or valid leasehold interests in, all
real property necessary or used in the ordinary conduct of its
business, and good title to all other property and assets
reflected in the Borrower's most recent consolidated financial
statements provided to the Lenders as owned by the Borrower,
except for such defects in title as could not, individually or in
the aggregate, reasonably be expected to have a Material Adverse
Effect and other than any sold, as permitted by Section 6.4. As
of the date of this Agreement, the property of the Borrower is
subject to no Liens other than a permitted pursuant to Section 6.1.

Section 4.12 Intellectual Property.

The Borrower owns or is licensed or otherwise has the right to
use all of the patents, trademarks, service marks, trade names,
copyrights, contractual franchises, authorizations and other
rights that are reasonably necessary for the operation of its
business, without conflict with the rights of any other Person,
except to the extent that noncompliance would not have a Material
Adverse Effect. To the knowledge of the Borrower, no slogan or
other advertising device, product, process, method, substance,
part or other material now employed, or now contemplated to be
employed, by the Borrower infringes upon any rights held by any
other Person, except to the extent that noncompliance would not
have a Material Adverse Effect. No claim or litigation regarding
any of the foregoing is pending or threatened, and no patent,
invention, device, application, principle or any statute, law,
rule, regulation, standard or code is pending or, to the
knowledge of the Borrower, proposed, which, in either case, could
reasonably be expected to have a Material Adverse Effect.

Section 4.13 ERISA.

          (a)  Each Plan is in compliance in all material
     respects with ERISA, the Code and other applicable federal
     or state law. Each Plan which is intended to qualify under
     Section 401(a) of the Code has received a favorable
     determination letter from the Internal Revenue Service and,
     to the best knowledge of the Borrower, nothing has occurred
     which would or could reasonably be expected to cause the
     loss of such qualification of any such Plan or related
     trust.

          (b)  There are no pending or, to the best knowledge of
     the Borrower, threatened claims (other than routine claims
     for benefits in the ordinary course), actions or lawsuits,
     or action by any governmental authority, with respect to any
     Plan which has resulted or could reasonably be expected to
     result in a Material Adverse Effect. To the best knowledge
     of the Borrower, there has been no prohibited transaction
     within the meaning of Section 4975 of the Code or Section
     406 ERISA or other material violation of the fiduciary
     responsibility rules with respect to any Plan which has
     resulted or could reasonably be expected to result in a
     Material Adverse Effect.

          (c)  No Reportable Event has occurred or is reasonably
     expected to occur with respect to any Pension Plan.

          (d)  The aggregate Unfunded Pension Liability for all
     Pension Plans (calculated based on the most recent actuarial
     report for each Pension Plan) does not exceed $15,000,000.

          (e)  Neither the Borrower nor any ERISA Affiliate has
     incurred nor does it reasonably expect to incur, any
     liability under Title IV of ERISA with respect to any
     Pension Plan (other than premiums due and not delinquent
     under Section 4007 of ERISA).

          (f)  Neither the Borrower nor any ERISA Affiliate has
     transferred any Unfunded Pension Liability to any Person or
     otherwise engaged in a transaction that could be subject to
     Section 4069 of ERISA.

          (g)  Neither the Borrower nor any ERISA Affiliate has
     incurred nor reasonably expects to incur any liability,
     other than Acquisition Liability (and no event has occurred
     which, with the giving of notice under Section 4219 of
     ERISA, would result in such liability), under Section 4201
     or 4243 of ERISA with respect to a Multiemployer Plan. As
     used in this paragraph, "Acquisition Liability" means
     liability immaterial to the Borrower, its business and
     operations when taken as a whole that is incurred in
     connection with an acquisition by the Borrower or any ERISA
     Affiliate.

                            ARTICLE V

                           ARTICLE VI
                       Negative Covenants

So long as any Note shall remain unpaid or the Facility shall be
outstanding, the Borrower agrees that, without the prior written
consent of the Required Lenders:

in, of or on the property of the Borrower, except:

          (a)  Liens for taxes, assessments of governmental
     charges or levies on its property if the same shall not at

             Events of Default, Rights and Remedies

Section 7.1 Events of Default.

"Event of Default", wherever used herein, means any one of the

          (a)  Default in the payment of any principal of any
     Note when it becomes due and payable.

          (b)  Default in the payment of any interest on any Note

     the same become due and payable and the continuance of such
     default for a period of five calendar days.

     specifically dealt with), and the continuance of such
     default or breach for a period of 30 days after the Lenders
     have given notice to the Borrower specifying such default or
     breach and requiring it to be remedied.

          (e)  Any representation or warranty made by the
     Borrower in this Agreement or by the Borrower (or any of its

          (f)  A default under either Mortgage Indenture or with
     respect to any other Funded Debt (other than any default
     dealt with elsewhere in this Section) and the expiration of
     the applicable period of grace, if any, specified in the
     applicable evidence of indebtedness, indenture or other
     instrument; provided, however, that no Event of Default
     shall be deemed to have occurred under this paragraph if the
     aggregate amount owing as to all such indebtedness as to
     which such defaults have occurred and are continuing is less
     than $15,000,000; provided further that if such default
     shall be cured by the Borrower, or waived by the holders of
     such indebtedness, in each case prior to the commencement of
     any action under Section 7.2 and as may be permitted by such
     evidence of indebtedness, indenture or other instrument,
     then the Event of Default hereunder by reason of such
     default shall be deemed likewise to have been thereupon
     cured or waived.

          (g)  The Borrower (i) ceases or fails to be Solvent, or

     in the ordinary course; (iii) commences any Insolvency
     Proceeding with respect to itself; or (iv) takes any action
     to effectuate or authorize any of the foregoing.

     commenced or filed against the Borrower, or any writ,
     judgment, warrant of attachment, execution or similar
     process is issued or levied against a substantial part of
     the Borrower's properties, and any such proceeding or
     petition shall not be dismissed, or such writ, judgment,
     warrant of attachment, execution or similar process shall
     not be released, vacated or fully bonded within 60 days
     after commencement, filing or levy; or (ii) the Borrower
     admits the material allegations of a petition against it in
     any Insolvency Proceeding, or an order for relief (or
     similar order under non-U.S. law) is ordered in any
     Insolvency Proceeding; or (iii) the Borrower acquiesces in
     the appointment of a receiver, trustee, custodian,
     conservator, liquidator, mortgagee in possession (or agent
     therefor), or similar Person for itself or a substantial
     portion of its property or business.

          (i)  A Change of Control shall occur with respect to
     the Borrower.

          (j)  The Borrower shall fail within 45 days to pay,
     bond or otherwise discharge any judgment or order for the
     payment of money in excess of $10,000,000, which is not
     stayed on appeal or otherwise being appropriately contested
     in good faith.

          (k)  (i) An ERISA Event or ERISA Termination Event
     which has resulted or would reasonably be expected to result

     amount in excess of 10% of Consolidated Net Worth; (ii) the
     commencement or increase of contributions to, or the
     adoption of or the amendment of, a Pension Plan by the
     Borrower or an ERISA Affiliate which has resulted or could
     reasonably be expected to result in an increase in Unfunded
     Pension Liability among all Pension Plans in an aggregate
     amount in excess of 10% of Consolidated Net Worth; or (iii)
     the Borrower's or an ERISA Affiliate's failure to pay when
     due, after the expiration of any applicable grace period,
     any installment payment with respect to its withdrawal
     liability under Section 4201 of ERISA under a Multiemployer
     Plan which has resulted or could reasonably be expected to
     result in a Material Adverse Effect.

          (l)  Any governmental authority or other administrative
     or legal authority having regulatory jurisdiction over the
     Borrower takes any action which has a Material Adverse
     Effect on the Borrower.

Section 7.2 Rights and Remedies.

Upon the occurrence of an Event of Default or at any time
thereafter until such Event of Default is cured to the written
satisfaction of the Required Lenders, the Agent may, with the
consent of the Required Lenders, and shall, at the request of the
Required Lenders, exercise any or all of the following rights and
remedies:

          (a)  The Agent may, by notice to the Borrower, declare
     the Facility to be terminated, whereupon the same shall
     forthwith terminate.

          (b)  The Agent may, by notice to the Borrower, declare
     the entire unpaid principal amount of the Notes then
     outstanding, all interest accrued and unpaid thereon, and
     all other amounts payable under this Agreement to be
     forthwith due and payable, whereupon the Notes, all such
     accrued interest and all such amounts shall become and be
     forthwith due and payable, without presentment, demand,
     protest or further notice of any kind, all of which are
     hereby expressly waived by the Borrower.

          (c)  The Lenders may exercise any other rights and
     remedies available to them by law or agreement.

Notwithstanding the foregoing, upon the occurrence of an Event of
Default described in Section 7.1(g) or 7.1(h) hereof, the entire
unpaid principal amount of the Notes then outstanding, all
interest accrued and unpaid thereon, and all other amounts
payable under this Agreement shall be immediately due and payable
without presentment, demand, protest or notice of any kind.

                          ARTICLE VIII
                            The Agent

Section 8.1 Authorization.

Each Lender and the holder of each Note irrevocably appoints and
authorizes the Agent to act on behalf of such Lender or holder to
the extent provided herein or in any document or instrument
delivered hereunder or in connection herewith, and to take such
other action as may be reasonably incidental thereto. In
furtherance of the foregoing, and not in limitation thereof, each
Lender irrevocably (i) authorizes the Agent to execute and
deliver and perform its obligations under this Agreement and each
of the Loan Documents to which the Agent is a party, and to
exercise all rights, powers and remedies that the Agent may have
hereunder or thereunder, (ii) appoints the Agent as nominal
beneficiary or nominal secured party, as the case may be, under
the Loan Documents and all related UCC-1 financing statements,
and (iii) authorizes the Agent to act as agent of and for such
Lender for purposes of holding, perfecting and disposing of any
collateral under the Loan Documents. As to any matters not
expressly provided for by this Agreement or the Loan Documents,
the Agent shall not be required to exercise any discretion or
take any action, but shall be required to act or to refrain from
acting (and shall be fully protected in so acting or refraining
from acting) upon the instructions of the Required Lenders or, if
so required pursuant to Section 9.2, upon the instructions of all
Lenders; provided, however, that except for action expressly
required of the Agent hereunder, the Agent shall in all cases be
fully justified in failing or refusing to act hereunder unless it
shall be indemnified to its satisfaction by the Lenders against
any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action, and the
Agent shall not in any event be required to take any action which
is contrary to this Agreement, the Loan Documents or applicable
law. The Agent shall not have a fiduciary relationship in respect
of the Borrower or any Lender by reason of this Agreement.

Section 8.2 Distribution of Payments and Proceeds.

          (a)  After deduction of any costs of collection, as
     provided in this Agreement and the other Loan Documents, and
     any fee payable to the Agent in its capacity as such under
     this Agreement, any Fee Letter or any other agreement, the
     Agent shall remit to each Lender that Lender's Percentage of
     all payments of principal and interest and of all fees and
     other amounts payable hereunder for the benefit of the
     Lenders that are received by the Agent under the Loan
     Documents. Each Lender's interest in the Loan Documents
     shall be payable solely from payments, collections and
     proceeds actually received by the Agent under the Loan
     Documents; and the Agent's only liability to the Lenders
     hereunder shall be to account for each Lender's Percentage
     of such payments, collections and proceeds in accordance
     with this Agreement. If the Agent is ever required for any
     reason to refund any such payments, collections or proceeds,
     each Lender will refund to the Agent, upon demand, its
     Percentage of such payments, collections or proceeds,
     together with its Percentage of interest or penalties, if
     any, payable by the Agent in connection with such refund.

          (b)  Notwithstanding the foregoing, if any Lender has
     wrongfully refused to fund its Percentage of any Borrowing
     or other Advance as required hereunder, or if the principal
     balance of any Lender's Note is for any other reason less
     than its Percentage of the aggregate principal balances of
     the Notes then outstanding, the Agent may remit all payments
     received by it to the other Lenders until such payments have
     reduced the aggregate amounts owed by the Borrower to the
     extent that the aggregate amount owing to such Lender
     hereunder is equal to its Percentage of the aggregate amount
     owing to all of the Lenders hereunder. The provisions of
     this paragraph are intended only to set forth certain rules
     for the application of payments, proceeds and collections in
     the event that a Lender has breached its obligations
     hereunder and shall not be deemed to excuse any Lender from
     such obligations.

Section 8.3 Expenses.

All payments, collections and proceeds received or effected by
the Agent may be applied, first, to pay or reimburse the Agent
for all costs, expenses, damages and liabilities at any time
incurred by or imposed upon the Agent in connection with this
Agreement or any other Loan Document (including but not limited
to all reasonable attorney's fees, foreclosure expenses and
advances made to protect the security of any collateral). If the
Agent does not receive payments, collections or proceeds
sufficient to cover any such costs, expenses, damages or
liabilities within 30 days after their incurrence or imposition,
each Lender shall, upon demand, remit to the Agent its Percentage
of the difference between (i) such costs, expenses, damages and
liabilities, and (ii) such payments, collections and proceeds,
together with interest on such amount for each day following the
thirtieth day after demand therefor until so remitted at a rate
equal to the Federal Funds Rate for each such day.

Section 8.4 Payments Received Directly by Lenders.

If any Lender or other holder of a Note shall obtain any payment
or other recovery (whether voluntary, involuntary, by application
of offset or otherwise) on account of the Obligations other than
through distributions made in accordance with Section 8.2, such
Lender or holder shall promptly give notice of such fact to the
Agent and shall purchase from the other Lenders or holders such
participations in the Obligations held by them as shall be
necessary to cause the purchasing Lender or holder to share the
excess payment or other recovery ratably with each of them;
provided, however, that if all or any portion of the excess
payment or other recovery is thereafter recovered from such
purchasing Lender or holder, the purchase shall be rescinded and
the purchasing Lender restored to the extent of such recovery
(but without interest thereon).

Section 8.5 Indemnification.

Each Lender severally (but not jointly) hereby agrees to
indemnify and hold harmless the Agent, as well as the Agent's
agents, employees, officers and directors, ratably according to
their respective Percentages from and against any and all losses,
liabilities (including liabilities for penalties), actions,
suits, judgment, demands, damages, costs, disbursements, or
expenses (including attorneys' fees and expenses) of any kind or
nature whatsoever, which are imposed on, incurred by, or asserted
against the Agent or its agents, employees, officers or directors
in any way relating to or arising out of this Agreement or the
Loan Documents, or as a result of any action taken or omitted to
be taken by the Agent; provided, however, that no Lender shall be
liable for any portion of any such losses, liabilities (including
liabilities for penalties), actions, suits, judgments, demands,
damages, costs disbursements, or expenses resulting from the
gross negligence or willful misconduct of the Agent.
Notwithstanding any other provision of the Loan Documents, the
Agent shall in all cases be fully justified in failing or
refusing to act hereunder unless it shall be indemnified to its
satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or
continuing to take any such action.

Section 8.6 Exculpation.

The Agent shall not be liable for any action taken or omitted to
be taken by the Agent in connection with this Agreement or the
Loan Documents, except for its own gross negligence or willful
misconduct. The Agent shall be entitled to rely upon advice of
counsel concerning legal matters, the advice of independent
public accountants with respect to accounting matters and advice
of other experts as to any other matters, and upon this
Agreement, any Loan Document and any schedule, certificate,
statement, report, notice or other writing which it believes to
be genuine or to have been presented by a proper person. Neither
the Agent nor any of its directors, officers, employees or agents
shall (a) be responsible for any recitals, representations or
warranties contained in, or for the execution, validity,
genuineness, effectiveness or enforceability of this Agreement,
any Loan Document, or any other instrument or document delivered
hereunder or in connection herewith, (b) be responsible for the
validity, genuineness, perfection, effectiveness, enforceability,
existence, value or enforcement of any collateral security, (c)
be under any duty to inquire into or pass upon any of the
foregoing matters, or to make any inquiry concerning the
performance by the Borrower or any other obligor of its
obligations, or (d) in any event, be liable as such for any
action taken or omitted by it or them, except for its or their
own gross negligence or willful misconduct. The agency hereby
created shall in no way impair or affect any of the rights and
powers of, or impose any duties or obligations upon, the Agent in
its individual capacity.

Section 8.7 Agent and Affiliates.

The Agent shall have the same rights and powers hereunder in its
individual capacity as any other Lender, and may exercise or
refrain from exercising the same as though it were not the Agent,
and the Agent and its affiliates may accept deposits from and
generally engage in any kind of business with the Borrower as
fully as if the Agent were not the Agent hereunder.

Section 8.8 Credit Investigation.

Each Lender acknowledges that it has made such inquiries and
taken such care on its own behalf as would have been the case had
its obligations hereunder been incurred and the Advances made
directly by such Lender to the Borrower without the intervention
of the Agent or any other Lender. Each Lender agrees and
acknowledges that the Agent makes no representations or
warranties about the creditworthiness of the Borrower or any
other party to this Agreement or with respect to the legality,
validity, sufficiency or enforceability of this Agreement, any
Loan Document, or any other instrument or document delivered
hereunder or in connection herewith.

Section 8.9 Resignation and Assignment of Agent.

          (a)  The Agent may resign as such at any time upon at
     least 30 days' prior notice to the Borrower and the Lenders.
     In the event of any resignation of the Agent, the Required
     Lenders shall as promptly as practicable appoint a successor
     Agent. If no such successor Agent shall have been so
     appointed by the Required Lenders and shall have accepted
     such appointment within 30 days after the resigning Agent's
     giving of notice of resignation, then the resigning Agent
     may, on behalf of the Lenders, appoint a successor Agent,
     which shall be a commercial bank organized under the laws of
     the United States of America or of any State thereof. Any
     such successor Agent shall have capital and retained
     earnings of at least $100,000,000.

          (b)  The Agent may, without the consent of the Borrower
     or the other Lenders, assign its rights and obligations as
     Agent hereunder and under the other Loan Documents to its
     parent or to any wholly owned subsidiary of its parent, and
     upon such assignment, the former Agent shall be deemed to
     have retired, and such wholly owned subsidiary shall be
     deemed to be a successor Agent. Any such successor Agent
     shall have capital and retained earnings of at least
     $100,000,000.

          (c)  Upon the acceptance of any appointment as Agent
     hereunder by a successor Agent, such successor Agent shall
     thereupon be entitled to receive from the prior Agent such
     documents of transfer and assignment as such successor Agent
     may reasonably request and the resigning or assigning Agent
     shall be discharged from its duties and obligations under
     this Agreement. After any resignation or assignment pursuant
     to this Section, the provisions of this Section shall inure
     to the benefit of the retiring Agent as to any actions taken
     or omitted to be taken by it while it was acting as Agent
     hereunder.

Section 8.10 Defaults.

The Agent shall not be deemed to have knowledge of the occurrence
of a Default or an Event of Default unless the Agent has received
notice from a Lender or the Borrower specifying the occurrence of
such Default or Event of Default. In the event that the Agent
receives such a notice of the occurrence of a Default or an Event
of Default, the Agent shall give prompt notice thereof to the
Lenders. The Agent shall (subject to Section 8.5 hereof) take
such actions with respect to such Default as shall be directed by
the Required Lenders; provided that, unless and until the Agent
shall have received such directions, the Agent may take any
action, or refrain from taking any action, with respect to such
Default as it shall deem advisable in the best interest of the
Lenders.

Section 8.11 Obligations Several.

The obligations of each Lender hereunder are the several
obligations of such Lender, and neither any Lender nor the Agent
shall be responsible for the obligations of any other Lender
hereunder, nor will the failure by the Agent or any Lender to
perform any of its obligations hereunder relieve the Agent or any
other Lender from the performance of its respective obligations
hereunder. Nothing contained in this Agreement, and no action
taken by any Lender or the Agent pursuant hereto or in connection
herewith or pursuant to or in connection with the Loan Documents
shall be deemed to constitute the Lenders, together or with or
without the Agent, as a partnership, association, joint venture,
or other entity.

                           ARTICLE IX
                          Miscellaneous

Section 9.1 No Waiver; Cumulative Remedies.

No failure or delay on the part of the Lenders in exercising any
right, power or remedy under the Loan Documents shall operate as
a waiver thereof; nor shall any Lender's acceptance of payments
while any Default or Event of Default is outstanding operate as a
waiver of such Default or Event of Default, or any right, power
or remedy under the Loan Documents; nor shall any single or
partial exercise of any such right, power or remedy preclude any
other or further exercise thereof or the exercise of any other
right, power or remedy under the Loan Documents. The remedies
provided in the Loan Documents are cumulative and not exclusive
of any remedies provided by law.

Section 9.2 Amendments, Etc.

No amendment or waiver of any provision of any Loan Document or
consent to any departure by the Borrower therefrom shall be
effective unless the same shall be in writing and signed by the
Required Lenders (or by the Agent with the consent or at the
request of the Required Lenders), and any such waiver shall be
effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on the Borrower
in any case shall entitle the Borrower to any other or further
notice or demand in similar or other circumstances.

Notwithstanding the foregoing:

          (a)  No such amendment or waiver shall be effective to
     do any of the following unless signed by each of the Lenders
     (or by the Agent with the consent or at the request of each
     of the Lenders):

          (i)  Increase the Facility Amount of any Lender or
               extend the Revolving Period Termination Date.

          (ii) Permit the Borrower to assign its rights under
               this Agreement.

          (iii)     Amend this Section, the definition of
               "Required Lenders" in Section 1.1, or any
               provision herein providing for consent or other
               action by all Lenders.

          (b)  No such amendment or waiver shall be effective to
     do any of the following unless signed by each of the Lenders
     affected thereby (or by the Agent with the consent or at the
     request of each of such Lenders):

           (i) Forgive any indebtedness of the Borrower arising
               under this Agreement or the Notes, or reduce the
               rate of interest or any fees charged under this
               Agreement or the Notes.

          (ii) Postpone or delay any date fixed by this Agreement
               or any other Loan Document for any payment of
               principal, interest, facility fees or other
               material amounts due to the Lenders (or any of
               them) hereunder or under any other Loan Document.

          (c)  No amendment, waiver or consent shall affect the
     rights or duties of the Agent under this Agreement or any
     other Loan Document unless in writing and signed by the
     Agent.

          (d)  No amendment, modification or (except as provided
     elsewhere herein) termination of this Agreement or waiver of
     any rights of the Borrower or obligations of any Lender or
     the Agent hereunder shall be effective unless the Borrower
     shall have consented thereto in writing.

Section 9.3 Notice.

Except as otherwise expressly provided herein, all notices and
other communications hereunder shall be in writing and shall be
(i) personally delivered, (ii) transmitted by registered mail,
postage prepaid, (iii) sent by Federal Express or similar
expedited delivery service, or (iv) transmitted by telecopy, in
each case addressed to the party to whom notice is being given at
its address or telecopier number (as the case may be) as set
forth in Exhibit A or in any applicable Assignment Certificate;
or, as to each party, at such other address or telecopier number
as may hereafter be designated in a notice by that party to the
other party complying with the terms of this Section. All such
notices or other communications shall be deemed to have been
given on (i) the date received if delivered personally or by
mail, (ii) the date of receipt, if delivered by Federal Express
or similar expedited delivery service, or (iii) the date of
transmission if delivered by telecopy, except that notices or
requests to the Agent or any Lender pursuant to any of the
provisions of Article II shall not be effective until received.

Section 9.4 Costs and Expenses.

The Borrower agrees to pay on demand all reasonable costs and
expenses incurred by the Agent in connection with the
negotiation, preparation, execution, administration, amendment or
enforcement of the Loan Documents and the other instruments and
documents to be delivered hereunder and thereunder, including the
reasonable fees and out-of-pocket expenses of counsel for any
Lender with respect thereto, whether paid to outside counsel or
allocated to the Agent by in-house counsel.

Section 9.5 Indemnification by Borrower.

The Borrower hereby agrees to indemnify the Agent and the Lenders
and each officer, director, employee and agent thereof (herein
individually each called an "Indemnitee" and collectively called
the "Indemnitees") from and against any and all losses, claims,
damages, reasonable expenses (including, without limitation,
reasonable attorneys' fees) and liabilities incurred by an
Indemnitee in connection with or arising out of the execution or
delivery of this Agreement or any agreement or instrument
contemplated hereby, the performance by the parties hereto of
their respective obligations hereunder or the use of the proceeds
of any Borrowing hereunder (including but not limited to any such
loss, claim, damage, expense or liability arising out of any
claim in which it is alleged that any Environmental Law has been
breached with respect to any activity or property of the
Borrower), except to the extent that such loss, claim, damage,
expense or liability was incurred as a result of the gross
negligence or willful misconduct of the applicable Indemnitee.
All obligations provided for in this Section shall survive any
termination of this Agreement.

Section 9.6 Execution in Counterparts.

This Agreement and the other Loan Documents may be executed in
any number of counterparts, each of which when so executed and
delivered shall be deemed to be an original and all of which
counterparts of this Agreement or such other Loan Document, as
the case may be, taken together, shall constitute but one and the
same instrument.

Section 9.7 Binding Effect; Assignment and Participations.

          (a)  Generally. The Loan Documents shall be binding
     upon and inure to the benefit of the Borrower and the
     Lenders and their respective successors and assigns, except
     that (i) the Borrower shall not have the right to assign its
     rights thereunder or any interest therein without the prior
     written consent of each of the Lenders, and (ii) except as
     set forth in this Section 9.7, no Lender may assign or grant
     any participation in any of its rights or obligations under
     any Loan Document.

          (b)  Participations. Any Lender may, at any time, grant
     participations in a portion of its Note and Commitment to
     any institutional investor on any date selected by such
     Lender. Any Lender proposing a participation hereunder shall
     give notice of such participation to the Agent at least ten
     Business Days prior to such participation (unless the Agent
     consents to a shorter period of time). Such notice shall
     specify the identity of the proposed purchaser of the
     participation and the amount of the proposed participation.
     No such partial participation shall be permitted if the
     principal amount thereof would be less than $5,000,000. No
     holder of any such participation, other than an affiliate of
     such Lender, shall be entitled to require such Lender to
     take or omit to take any action hereunder, except that such
     Lender may agree with such participant that such Lender will
     not, without such participant's consent, (i) forgive any
     indebtedness of the Borrower under this Agreement or the
     Notes, (ii) agree to reduce the rate of interest charged
     under this Agreement, or (iii) agree to extend the final
     maturity of any indebtedness evidenced by the Notes, except
     as expressly provided by the terms of the Loan Documents. No
     Lender shall, as between the Borrower and such Lender, be
     relieved of any of its obligations hereunder as a result of
     any such granting of a participation. The Borrower hereby
     acknowledges and agrees that any participant described in
     this Section will, for purposes of Section 2.10(b), be
     considered to be a Lender hereunder (provided that such
     participant shall not be entitled to receive any more than
     the Lender selling such participation would have received
     had such sale not taken place) and may rely on, and possess
     all rights under, any opinions, certificates, or other
     instruments or documents delivered under or in connection
     with any Loan Document (it being understood that each
     opinion delivered hereunder speaks only as of the date
     thereof).

          (c)  Assignments. Any Lender may, at any time, assign a
     portion of its Note and Commitment to an Eligible Lender (an
     "Applicant") on any date (the "Adjustment Date") selected by
     such Lender. Any Lender proposing an assignment hereunder
     shall give notice of such assignment to the Agent at least
     ten Business Days prior to such assignment (unless the Agent
     consents to a shorter period of time). Such notice shall
     specify the identity of such Applicant and the Percentage
     which it proposes that such Applicant acquire (which
     Percentage shall be the same for the Commitment and the Note
     held by the assigning Lender). No such partial assignment
     shall be permitted if, immediately after giving effect to
     such assignment, either the Credit Exposure of the Applicant
     or the Credit Exposure of the assigning Lender would be less
     than $5,000,000. The notice of assignment shall contain a
     representation by the Applicant to the effect that none of
     the consideration used to make the purchase of the Note and
     Commitment under the applicable assignment agreement
     constitutes "plan assets" as defined under ERISA and that
     the rights and interests of the Applicant in and under the
     Loan Documents will not be "plan assets" under ERISA. Any
     Lender making an assignment under this Section shall pay the
     Agent a transfer fee in the amount of $3,500 simultaneously
     with such assignment.

          (d)  Consents. Any assignment hereunder may be made,
     and any participation granted, only with the prior written
     consent of the Agent and the Borrower; provided, however,
     that (i) in no event shall such consent be unreasonably
     withheld, (ii) the consent of the Borrower shall not be
     required if any Default or Event of Default has occurred and
     is continuing at the time of such assignment or grant of
     participation, (iii) no such consent of the Borrower and the
     Agent shall be required for the assignment by any Lender of,
     or grant of a participation in, all or any part of its
     Commitment and Note to one or more other Persons that are
     Lenders immediately prior to such assignment, and (iv) no
     such consent of the Borrower and the Agent shall be required
     for the assignment by any Lender of, or grant of a
     participation in, all or any part of its Commitment and Note
     to one or more affiliates of such Lender, provided that,
     unless consented to by the Borrower and the Agent (which
     consent shall not be unreasonably withheld), no such
     assignment under this clause (iv) shall relieve the
     transferring Lender from its obligations hereunder.

          (e)  Assignment Certificate and Notes. To confirm the
     status of each Additional Lender as a party to this
     Agreement and to evidence the assignment in accordance
     herewith:

           (i) the Borrower, such Lender, such Applicant, and the
               Agent shall, on or before the Adjustment Date,
               execute and deliver to the Agent an Assignment
               Certificate in substantially the form of Exhibit D
               (an "Assignment Certificate") (provided that the
               assignment will be effective without the signature
               of the Borrower or the Agent to the extent that
               the consent of the Borrower or the Agent, as the
               case may be, is not required hereunder); and

          (ii) the Borrower will, at its own expense, execute and
               deliver to the Additional Lender a new Note,
               payable to the order of the Additional Lender in
               an amount corresponding to the applicable interest
               in the assigning Lender's rights and obligations
               acquired by such Applicant pursuant to such
               assignment, and, if the assigning Lender has
               retained interests in such rights and obligations,
               a new Note, payable to the order of that Lender in
               an amount corresponding to such retained
               interests. Such new Notes shall be in an aggregate
               principal amount equal to the aggregate principal
               amount of the applicable Note to be replaced by
               such new Notes, shall be dated the effective date
               of such assignment and shall otherwise be in the
               form of the Note to be replaced thereby. Such new
               Notes shall be issued in substitution for, but not
               in satisfaction or payment of, the Notes being
               replaced thereby.

     Upon the execution and delivery of such Assignment
     Certificate and such Notes, (a) this Agreement shall be
     deemed to be amended to the extent, and only to the extent,
     necessary to reflect the addition of such Additional Lender
     and the resulting adjustment of Percentages arising
     therefrom, (b) the assigning Lender shall be relieved of all
     obligations hereunder to the extent of the reduction of all
     obligations hereunder and to the extent of the reduction of
     such Lender's Percentage, and (c) the Additional Lender
     shall become a party hereto and shall be entitled to all
     rights, benefits and privileges accorded to a Lender herein
     and in each other document or instrument executed pursuant
     hereto and subject to all obligations of a Lender hereunder,
     including the right to approve or disapprove actions which,
     in accordance with the terms hereof, require the approval of
     the Required Lenders or all Lenders, and the obligations to
     make Advances hereunder.

          (f)  Federal Reserve Bank Security Interests.
     Notwithstanding the foregoing, each Lender may at any time
     grant a security interest in all or any portion of its
     rights under this Agreement and that Lender's Note in favor
     of any Federal Reserve Bank in accordance with Regulation A
     of the Board of Governors of the Federal Reserve System.

          (g)  Borrower Cooperation. In order to facilitate the
     addition of Additional Lenders hereto, the Borrower shall
     cooperate fully with each Lender and the Agent in connection
     therewith and shall provide all reasonable assistance
     requested by each Lender and the Agent relating thereto,
     including, without limitation, the furnishing of such
     written materials and financial information regarding the
     Borrower as any Lender or the Agent may reasonably request,
     the execution of such documents as any Lender or the Agent
     may reasonably request with respect thereto, and the
     participation by officers of the Borrower in a meeting or
     teleconference call with any Applicant upon the reasonable
     request of any Lender or the Agent.

Section 9.8 Disclosure of Information.

The Agent and the Lenders shall keep confidential (and cause
their respective officers, directors, employees, agents and
representatives to keep confidential) all information, materials
and documents furnished by the Borrower, the Agent or the Lenders
(the "Disclosed Information"). Notwithstanding the foregoing, the
Agent and each Lender may disclose Disclosed Information (i) to
the Agent, any other Lender or any Affiliate of any Lender;
(ii) to legal counsel, accountants and other professional
advisors to the Agent or such Lender; (iii) to any regulatory
body having jurisdiction over any Lender or the Agent; (iv) to
the extent required by applicable laws and regulations or by any
subpoena or similar legal process, or requested by any
governmental agency or authority; (v) to the extent such
Disclosed Information (A) becomes publicly available other than
as a result of a breach of this Agreement, (B) becomes available
to the Agent or such Lender on a non-confidential basis from a
source other than the Borrower or a Subsidiary, or (C) was
available to the Agent or such Lender on a non-confidential basis
prior to its disclosure to the Agent or such Lender by the
Borrower or a Subsidiary; (vi) to the extent the Borrower or such
Subsidiary shall have consented to such disclosure in writing;
(vii) to the extent reasonably deemed necessary by the Agent or
any Lender in the enforcement of the remedies of the Agent and
the Lenders provided under the Loan Documents; or (viii) in
connection with any potential assignment or participation in the
interest granted hereunder, provided that any such potential
assignee or participant shall have executed a confidentiality
agreement imposing on such potential assignee or participant
substantially the same obligations as are imposed on the Agent
and the Lenders under this Section 9.8.

Section 9.9 Governing Law.

The Loan Documents shall be governed by, and construed in
accordance with, the laws of the State of New York.

Section 9.10 Consent to Jurisdiction.

Each of the Borrower, the Agent and the Lenders irrevocably
(i) agrees that any suit, action or other legal proceeding
arising out of or relating to this Agreement or any other Loan
Document shall be brought in a court of record in Hennepin County
in the State of Minnesota or in the courts of the United States
located in such State, (ii) consents to the jurisdiction of each
such court in any suit, action or proceeding, (iii) waives any
objection which it may have to the laying of venue of any such
suit, action or proceeding in any such courts and any claim that
any such suit, action or proceeding has been brought in an
inconvenient forum, and (iv) agrees that a final judgment in any
such suit, action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any
other manner provided by law after all appeals have been
exhausted.

Section 9.11 Waiver of Jury Trial.

THE BORROWER, THE AGENT AND THE LENDERS HEREBY WAIVE TRIAL BY
JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR
OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED
WITH THIS AGREEMENT AND THE NOTES OR THE RELATIONSHIPS
ESTABLISHED HEREUNDER.

Section 9.12 Severability of Provisions.

Any provision of this Agreement which is prohibited or
unenforceable shall be ineffective to the extent of such
prohibition or unenforceability without invalidating the
remaining provisions hereof.

Section 9.13 Prior Agreements.

This Agreement and the other Loan Documents and related documents
described herein restate and supersede in their entirety any and
all prior agreements and understandings, oral or written, between
the Lenders and the Borrower.

Section 9.14 Other Financing.

If at any time from and after the effective date of this
Agreement, the Borrower shall enter into any trust indenture,
credit agreement or other agreement for, relating to, or amending
any terms or conditions applicable to any unsecured indebtedness
in an amount not less than $15,000,000, the Borrower shall
promptly so advise the Agent. Thereupon, if the Required Lenders
shall determine that such trust indenture, credit agreement or
other agreement includes covenants or defaults reasonably
determined by the Required Lenders to be more restrictive than
those provided for in Articles V and VI and shall request by
notice to the Borrower, the Borrower shall enter into an
amendment to this Agreement providing for substantially the same
such covenants and defaults as those provided for in such trust
indenture, credit agreement or other agreement, to the extent
required and as may be selected by the Required Lenders, such
amendment to remain in effect for the entire duration of the term
to maturity of such indebtedness (to and including the date to
which the same may be extended); provided, however, that if any
such trust indenture, credit agreement or other agreement shall
be modified, supplemented, amended or terminated so as to modify,
amend or eliminate such trust indenture or other agreement or any
such covenant, term, condition or default so made a part of this
Agreement, then, the Borrower shall give the Agent and the
Lenders prompt notice thereof and such modification, supplement
or amendment shall operate to modify, amend or eliminate such
covenants, term, condition or default as so made a part of this
Agreement. Notwithstanding the foregoing, in no event shall this
Section 9.14 be construed so as to require the Borrower at any
time to grant any Lien in favor of the Agent or the Lenders
hereunder.

Section 9.15 Termination of Existing Credit Facility.

Upon execution and delivery of this Agreement by each of the
parties hereto and satisfaction of the conditions precedent set
forth in Section 3.1, (i) the Existing Credit Facility shall be
deemed terminated, and (ii) no Lender (as defined in the Existing
Credit Agreement) shall have any further obligation with respect
to the Existing Credit Facility. Notwithstanding the foregoing,
the Borrower shall continue to have the obligation to pay any
principal, interest, fees and other amounts remaining unpaid
under the Existing Credit Facility, and the Lenders shall have no
obligation to effect any Borrowing hereunder until such amounts
have been paid in full or unless such amounts are paid in full by
the proceeds of the first Borrowing hereunder.

Section 9.16 Headings.
