               --------------------
               (a)  Subject to the terms and conditions hereof, at any time and
       from time to time from the Closing Date through the Maturity Date, each
       Lender may in its sole and absolute discretion make Competitive Advances
       to Borrower in such principal amounts as Borrower may request pursuant to
       a Competitive Bid Request, provided that giving effect to the requested
                                  --------
       Competitive Advance, the sum of (i) the outstanding principal amount of
                                ------
       the Committed Loans plus (ii) the Aggregate Effective Amount of all
                           ----
       outstanding Letters of Credit, plus (iii) the outstanding principal
                                      ----
       amount of the Competitive Advances shall not exceed the Main
       Commitment.

               (b)  Borrower shall request Competitive Advances by submitting a
       Competitive Bid Request to the Administrative Agent, which Competitive
       Bid Request shall specify the relevant date, amount and maturity for the
       proposed Competitive Advance and shall state that a Competitive Bid is
       requested on the basis of either an absolute, all-in rate (an "All-In
       Bid") or the basis of a margin over the Eurodollar Rate (a "Eurodollar
       Bid").  Any Competitive Bid Request made by telephone shall promptly be
       confirmed by the delivery to Administrative Agent in person or by
       telecopier of a written Competitive Bid Request.  The Competitive Bid
       Request must be received by the Administrative Agent not later than
       11:00 a.m. on a Banking Day that is (i) in the case of each All-In Bid,
       at
       least two (2) Banking Days prior, and (ii) in the case of each Eurodollar
       Bid, at least four (4) Banking Days prior, to the date of the proposed
       Competitive Advance.


                                                  -28

               (c)  Unless the Administrative Agent otherwise agrees, in its
       sole and absolute discretion, no Competitive Bid Request shall be made by
       Borrower if Borrower has, within the immediately preceding five (5)
       Banking Days, submitted another Competitive Bid Request.

               (d)  Each Competitive Bid Request must be made for a Competitive
       Advance of at least $5,000,000 and shall be in an integral multiple of
       $1,000,000.

               (e)  No Competitive Bid Request shall be made for a Competitive
       Advance with a maturity of less than 14 days or more than 180 days, or
       with a maturity date subsequent to the Maturity Date.

               (f)  The Administrative Agent shall, promptly after receipt of a
       Competitive Bid Request, notify the Lenders thereof by telephone and
       provide the Lenders a copy thereof by telecopier.  Any Lender may, by
       written notice to the Administrative Agent, advise the Administrative
       Agent that it elects not to be so notified of Competitive Bid Requests,
       in which case the Administrative Agent shall not notify such Lender of
       the Competitive Bid Request.

               (g)  Each Lender receiving a Competitive Bid Request may, in its
       sole and absolute discretion, make or not make a Competitive Bid
       responsive to the Competitive Bid Request.  Each Competitive Bid shall be
       submitted to the Administrative Agent not later than 8:00 a.m.
       (California time) (i) in the case of each Absolute Bid on the Business
       Day of the
       proposed Competitive Advance and (ii) in the case of each Eurodollar Bid,
       on the date which is three Business Days prior to the date of the
       requested Competitive Advance.  Any Competitive Bid received by the
       Administrative Agent after 8:00 a.m. on such dates shall be disregarded
       for purposes of this Agreement.  Any Competitive Bid made by telephone
       shall promptly be confirmed by the delivery to the Administrative Agent
       in person or by telecopier of a written Competitive Bid.

               (h)  Each Competitive Bid shall specify the All-In Bid or the
       Eurodollar Bid as requested in the Competitive Bid Request for the
       offered Maximum Competitive Advance set forth in the Competitive Bid.
       The Maximum Competitive Advance offered by a Lender
       in a Competitive Bid may be less
       than the Competitive Advance requested by Borrower in the Competitive Bid
       Request, but shall be an integral multiple of $1,000,000.  Any
       Competitive Bid which offers an interest rate other than an All-In Bid or
                                                     ----------
       Eurodollar Bid (as


                                                  -29-

       requested in the Competitive Bid Request), is in a form other than set
       forth in Exhibit D or which otherwise contains any term, condition or
                ---------
       provision not contained in the Competitive Bid Request shall be
       disregarded for purposes of this
       Agreement.  A Competitive Bid once submitted to the Administrative Agent
       shall be irrevocable until 9:00 a.m. (California time) on the date upon
       which Borrower must accept or reject such Competitive Bid (as set forth
       in (j) below), and shall expire by its terms at such time unless
       accepted by Borrower prior thereto.

               (i)  Promptly after 9:00 a.m. on the date upon which it receives
       Competitive Bids, the Administrative Agent shall notify Borrower of the
       names of any Lenders which have made Competitive Bids at or before
       8:00 a.m. (California time) on that date, provided that if the Lender
                                                 --------
       which serves as the Administrative Agent intends to make a Competitive
       Bid, it shall do
       so by notifying Borrower prior to 7:45 a.m. on that date.  In each case,
       the Administrative Agent shall inform Borrower of the Maximum Competitive
       Advance and All-In Bid or Eurodollar Bid (as applicable) set
       forth by each Lender in its Competitive Bid.
       The Administrative Agent shall promptly confirm such notifications in
       writing delivered in person or by telecopier to Borrower.

               (j)  Borrower may, in its sole and absolute discretion, reject
       any
       or all of the Competitive Bids.  If Borrower accepts any Competitive Bid,
       the following shall apply:  (a) Borrower must accept all Competitive Bids
       at all lower interest rates before accepting any portion of a Competitive
       Bid at a higher interest rate, (b) if two or more Lenders have submitted
       a Competitive Bid at the same interest rate, then Borrower must accept
       either all of such Competitive Bids or accept such Competitive Bids in
       the same proportion as the Maximum Competitive Advance of each Lender
       bears to the aggregate Maximum Competitive Advances of all such Lenders
       and (c) Borrower may not accept Competitive Bids for an aggregate amount
       in excess of the requested Competitive Advance set forth in the
       Competitive Bid Request.  Acceptance of a Competitive Bid by Borrower
       shall be
       irrevocable upon communication thereof to the Administrative Agent.  The
       Administrative Agent shall promptly notify each of the Lenders whose
       Competitive Bid has been accepted by Borrower by telephone, which
       notification shall promptly be confirmed in writing delivered in person
       or by telecopier to such Lenders.  Any Competitive Bid not accepted by
       Borrower by 9:00 a.m. (California time) on the date of the proposed
       Competitive Bid shall be deemed rejected.


                                                  -30-

               (k)  A Lender whose Competitive Bid has been accepted by Borrower

       Request and with its Competitive Bid, subject to the applicable
       conditions set forth in this Agreement by making funds immediately
       available to the
       Administrative Agent at the Administrative Agent's Office in the amount
       of such Competitive Advance not later than 11:00 a.m. (California time)
       on the date of such acceptance.  The Administrative Agent shall then
       promptly credit the Competitive Advance in immediately available funds to
       the Designated Deposit Account.

               (l)  The Administrative Agent shall notify Borrower and the
       Lenders promptly after any Competitive Advance is made of the amounts and

               (b)  Each Request for Letter of Credit shall be submitted to the
       Issuing Lender, with a copy to the Administrative Agent, at least three
       (3) Banking Days prior to the date upon which the related Letter of

       is proposed to be issued.  The Administrative Agent shall promptly notify
       the Issuing Lender whether such Request for Letter of Credit, and the
       issuance of a Letter of Credit pursuant thereto, conforms to the
       requirements of this Agreement.  Upon issuance of a Letter of Credit, the
       Issuing Lender shall promptly notify the Administrative Agent, and the

       the amount of such payment.  The obligation of each Lender to so
       reimburse
       the Issuing Lender shall be absolute and unconditional and shall not be

       on such amount from the date of any payment made by the Issuing Lender at
       the rate applicable to Alternate Base Rate Loans for three Business Days

       payment shall be used to reimburse the Issuing Lender for the payment
       made
       by it under the Letter of Credit and, to the extent that the Lenders have
       not reimbursed the Issuing Lender pursuant to Section 2.6(c), the
                                                             -----
       interest amount of any such payment

       Share of any payment made by the Issuing Lender under a Letter of Credit
       shall thereupon
       acquire a pro rata participation, to the extent of such reimbursement, in
       the claim of
       the Issuing Lender against Borrower for reimbursement of principal and
       interest under this Section 2.6(d) and shall share, in accordance with
                                   -----
       that pro rata participation, in any principal payment made by Borrower
       with respect to such claim and
       in any interest payment made by Borrower (but only with respect to
       periods
       subsequent to the date such Lender reimbursed the Issuing Lender) with
       respect to such claim.

               (e)  Borrower may, pursuant to a Request for Loan, request that
       Advances be made pursuant to Section 2.1(a) to provide funds for the
                                            -----
       payment required by Section 2.6(d) and, for this purpose, the conditions

       precedent set forth in Article 8
                              ---------
       shall not apply.  The proceeds of such Advances shall be paid directly to
       the Issuing Lender to reimburse it for the payment made by it under the
       Letter of Credit.

               (f)  If Borrower fails to make the payment required by
       Section 2.6(d) within the time period therein set forth, in lieu of the
               ------
       reimbursement to the Issuing Lender under Section 2.4(c) the Issuing
                                                         ------
       Lender may (but is not required to), without notice to or the consent of
       Borrower,
       instruct the Administrative Agent to cause Advances to be made by the
       Lenders under the
       Commitment in an aggregate amount equal to the amount paid by the Issuing
       Lender with
       respect to that Letter of Credit and, for this purpose, the conditions
       precedent set forth in Article 8 shall not apply.  The proceeds of such
                              ---------
       Advances shall be paid directly to the Issuing Lender to reimburse it for
       the payment made by it under the Letter of Credit.

               (g)  The issuance of any supplement, modification, amendment,
       renewal, or extension to or of any Letter of Credit shall be treated in
       all respects the same as the issuance of a new Letter of Credit.

               (h)  The obligation of Borrower to pay to the Issuing Lender the
       amount of any payment made by the Issuing Lender under any Letter of
       Credit shall be absolute, unconditional, and irrevocable, subject only to
       performance by the Issuing Lender of its obligations to Borrower under
       Uniform Commercial Code Section 5109.  Without limiting the foregoing,

               Credit, this Agreement, or any other agreement or instrument
               relating thereto;

                    (ii)      any amendment or waiver of or any consent to

               agreement or instrument relating thereto, with the consent of
               Borrower;

                    (iii)     the existence of any claim, setoff, defense, or

               Issuing Lender, the Administrative Agent or any Lender, any
               beneficiary of the Letter of Credit (or any persons or entities
               for whom any such beneficiary may be acting) or any other Person,
               whether in connection with the Letter of Credit, this Agreement,
               or any other agreement or instrument relating thereto, or any
               unrelated transactions;

                    (iv) any demand, statement, or any other document presented

such amount available to the Administrative Agent on the date of the Loan and

date such corresponding amount was made available by the Administrative Agent to
Borrower to the date such corresponding amount is recovered by the
Administrative Agent, at a rate per annum equal to the Federal Funds Rate.

     3.6  Increased Commitment Costs.  If any Lender determines in good faith

that compliance
with any Law or regulation enacted or promulgated after the Closing Date, or
with any guideline or request from any central bank or other Governmental Agency
issued or made after the Closing Date (whether or not having the force of Law)
has or would have the effect of reducing the rate of return on the capital of
such Lender or any corporation controlling such Lender as a consequence of, or
with reference to, such Lender's portion of the Commitment or its making or
maintaining of Advances or Swing Line Loans, below the rate which the Lender or
such other corporation could have achieved but for such compliance (taking into
account the policies of such Lender or corporation with regard to capital), then
the Borrower shall from time to time, upon demand by such Lender (with a copy of
such demand to the Administrative Agent), immediately pay to such Lender
additional amounts sufficient to compensate such Lender or other corporation for
such reduction.  A certificate as to such amounts, submitted to the Borrower and
the Administrative Agent by such Lender, shall be conclusive and binding for all
purposes, absent manifest error.  Each Lender agrees promptly to notify the
Borrower and the Administrative Agent of any circumstances that would cause the
Borrower to pay additional amounts pursuant to this Section, provided that the
                                                             --------
failure to give such notice shall not affect the Borrower's obligation to pay
such additional amounts hereunder.

     3.7  Eurodollar Fees and Costs.
          -------------------------

               (a)  If, after the date hereof, the existence or occurrence of
       any Special Eurodollar Circumstance:

                    (1)  shall subject any Lender or its Eurodollar Lending
            Office to any tax, duty or other charge or cost with respect to any
            Eurodollar Rate Advance, its Notes or its obligation to make
            Eurodollar Rate Advances, or shall change the basis of taxation of
            payments to any Lender of the principal of or interest on any
            Eurodollar Rate Advance or any other amounts due under this
            Agreement
            in respect of any Eurodollar Rate Advance, its Notes or its
            obligation to make Eurodollar Rate Advances (except for changes in
                                                         ------
            any tax on the overall net income, gross income or gross receipts of
            such Lender or
            its Eurodollar Lending Office);

                    (2)  shall impose, modify or deem applicable any reserve
            (including, without limitation, any reserve imposed by the Board of
             ---------
            Governors of
            the Federal Reserve System), special deposit or similar requirements
            against assets of, deposits with or for the account of, or credit
            extended by, any Lender or its Eurodollar Lending Office; or

                    (3)  shall impose on any Lender or its Eurodollar Lending
            Office or the Designated Eurodollar Market any other condition
            affecting any Eurodollar Rate Advance, its Notes, its obligation to
            make Eurodollar Rate Advances or this Agreement, or shall otherwise
            affect any of the same;

       and the result of any of the foregoing, as determined by such Lender,
       increases the cost to such Lender or its Eurodollar Lending Office of
       making or maintaining any Eurodollar Rate Advance or in respect of any
       Eurodollar Rate Advance, its Notes or its obligation to make Eurodollar
       Rate Advances or reduces the amount of any sum received or receivable by
       such Lender or its Eurodollar Lending Office with respect to any
       Eurodollar Rate Advance, its Notes or its obligation to make Eurodollar
       Rate Advances (assuming such Lender's Eurodollar Lending Office had
       funded
       100% of its Eurodollar Rate Advance in the Designated Eurodollar Market),
       then, upon demand by such Lender (with a copy to the Administrative
       Agent), Borrower shall pay to such Lender such additional amount or
       amounts as will compensate such Lender for


                                                  -42-


       such increased cost or reduction (determined as though such Lender's
       Eurodollar Lending Office had funded 100% of its Eurodollar Rate Advance
       in the Designated Eurodollar Market).  A statement of any Lender claiming
       compensation under this subsection shall be conclusive in the absence of
       manifest error.  Each Lender agrees to endeavor promptly to notify
       Borrower of any event of which it has actual knowledge, occurring after
       the Closing Date, which will entitle such Lender to compensation pursuant
       to this Section, and agrees to designate a different Eurodollar Lending
       Office if such designation will avoid the need for or reduce the amount
       of
       such compensation and will not, in the judgment of such Lender, otherwise
       be disadvantageous to such Lender.  If any Lender claims compensation
       under this Section, Borrower may at any time, upon at least four (4)
       Eurodollar Banking Days' prior notice to the Administrative Agent and
       Lenders and upon payment in full of the amounts provided for in this
       Section through the date of such payment plus any prepayment fee required
       by Section 3.7(d), pay in full all Eurodollar Rate Advances or request
                  -----
       that all Eurodollar Rate Advances be converted to Base Rate Advances.

               (b)  If, after the date hereof, the existence or occurrence of
       any
       Special Eurodollar Circumstance shall, in the opinion of any Lender, make
       it unlawful, impossible or impracticable for such Lender or its
       Eurodollar
       Lending Office to make, maintain or fund its portion of any Eurodollar
       Rate Loan, or materially restrict the authority of such Lender to
       purchase
       or sell, or to take deposits of, dollars in the Designated Eurodollar
       Market, or to determine or charge interest rates based upon the
       Eurodollar
       Rate, and such Lender shall so notify the Administrative Agent and the
       other Lenders, then the Lenders' obligation to make Eurodollar Rate
       Advances shall be suspended for the duration of such illegality,
       impossibility or impracticability and the Administrative Agent forthwith
       shall give notice thereof to Borrower.  Upon receipt of such notice, the
       outstanding principal amount of all Eurodollar Rate Advances, together
       with accrued interest thereon, automatically shall be converted to Base
       Rate Advances with Eurodollar Periods corresponding to the Eurodollar
       Loans of which such Eurodollar Rate Advances were a part on either (1)
       the
       last day of the Eurodollar Period(s) applicable to such Eurodollar Rate
       Advances if the affected Lender may lawfully continue to maintain and
       fund
       such Eurodollar Rate Advances to such day(s) or (2) immediately if the
       affected Lender may not lawfully continue to fund and maintain such
       Eurodollar Rate Advances to such day(s), provided that in such event the
                                                --------
       conversion shall
       not be subject to payment of a prepayment fee under Section 3.7(d).
                                                                   ------


                                                  -43-

               (c)  If, with respect to any proposed Eurodollar Rate Loan:

                    (1)  the Administrative Agent reasonably determines that, by
            reason of circumstances affecting the Designated Eurodollar Market
            generally that are beyond the reasonable control of the Lenders,
            deposits in dollars (in the applicable amounts) are not being
            offered
            to each of the Lenders in the Designated Eurodollar Market for the
            applicable Eurodollar Period; or

                    (2)  the Majority Lenders advise the Administrative Agent
            that the Eurodollar Rate as determined by the Administrative Agent
            (i) does not represent the effective pricing to such Lenders for
            deposits in dollars in the Designated Eurodollar Market in the
            relevant amount for the applicable Eurodollar Period, or (ii) will
            not adequately and fairly reflect the cost to such Lenders of making
            the applicable Eurodollar Rate Advances;

       then the Administrative Agent forthwith shall give notice thereof to
       Borrower and the Lenders, whereupon until the Administrative Agent
       notifies Borrower that the circumstances giving rise to such suspension
       no
       longer exist, the obligation of the Lenders to make any future Eurodollar
       Rate Advances shall be suspended.  If at the time of such notice there is
       then pending a Request for Loan that specifies a Eurodollar Rate Loan,
       such Request for Loan shall be deemed to specify a Base Rate Loan.

               (d)  Upon payment or prepayment of any Eurodollar Rate Advance,
       (other than as
       the result of a conversion required under Section 3.7(b)), on a day other
                                                         -------
       than the last day in the applicable Eurodollar
       Period (whether voluntarily,
       involuntarily, by reason of acceleration, or otherwise), or upon the
       failure of Borrower to borrow on the date or in the amount specified for
a
       Eurodollar Rate Loan in any Request for Loan, Borrower shall pay to the
       appropriate Lender a prepayment fee or failure to borrow fee, as the case
       may be, calculated as follows (and determined as though 100% of the
       Eurodollar Rate Advance had been funded in the Designated Eurodollar
       Market):

                    (1)  principal amount of the Eurodollar Rate Advance, times
                                                                          -----
           [number of days between the date of prepayment and the last day


                                                  -44-

            in the applicable Eurodollar Period], divided by 360, times the
                                                  -------         -----
            applicable  Interest Differential; plus
                                               ----

                         (2)  all actual out-of-pocket expenses (other than
            those
            taken into account in the calculation of the Interest Differential)
            incurred by the Lender (excluding allocations of any expense
                                    ---------
            internal
            to that Lender) and reasonably attributable to such payment or
            prepayment;

       provided that no prepayment fee or failure to borrow fee shall be payable
       --------
       (and no
       credit or rebate shall be required) if the product of the foregoing
       formula is not a positive number.  Each Lender's determination of the
       amount of any prepayment fee or failure to borrow fee  payable under this
       Section 3.7(d) shall be conclusive in the  absence of manifest error.
               ------

     3.8  Default Rate.  From and after the occurrence of any Event of Default
          ------------
the Loans and the Swing Line Loans shall bear interest at a fluctuating interest
rate per annum at all times equal to the sum of the Base Rate plus 3% per annum,
                                         --- --               ----
to the fullest extent permitted by applicable Laws.  Accrued and unpaid interest
on past due amounts (including, without limitation, interest on past due
                     ---------
interest) shall be compounded quarterly, on the last day of each calendar
quarter, to the fullest extent permitted by applicable Laws.

     3.9  Computation of Interest and Fees.  Computation of interest on Base
          --------------------------------
Rate Loans, Swing
Line Loans, Eurodollar Rate Loans, Competitive Advances and on facility and
letter of credit fees shall be calculated on the basis of a year of 360 days and
the actual number of days elapsed.  Borrower acknowledges that this calculation
method will result in a higher yield to the Lenders than a method based on a
year
of 365 or 366 days.  Any Loan or Swing Line Loan that is repaid on the same day
on which it is made shall bear interest for one day.  Notwithstanding anything
in this Agreement to the contrary, interest in excess of the maximum amount
permitted by applicable Laws shall not accrue or be payable hereunder or under
the Notes, and any amount paid as interest hereunder or under the Notes which
would otherwise be in excess of such maximum permitted amount shall instead be
treated as a payment of principal.

     3.10  Non-Banking Days.  If any payment to be made by Borrower or any other
           ----------------
Party under any Loan Document shall come due on a day other than a Banking Day,
payment shall
instead be considered due on the next succeeding Banking Day and the extension
of time shall be reflected in computing interest.


                                                  -45-

     3.11  Manner and Treatment of Payments.
           --------------------------------

               (a)  Each payment hereunder or on the Notes or under any other
       Loan Document shall be made to the Administrative Agent for the account
       of
       each of the Lenders, or the Administrative Agent, as the case may be, in
       immediately available funds not later than 11:00 a.m. (or, in the case of
       payments with respect to Swing Line Loans, not later than 12:00 noon) on
       the day of payment (which must be a Banking Day).  All payments received
       after 11:00 a.m. (or, in the case of payments with respect to Swing Line
       Loans, not later than 12:00 noon) on any particular Banking Day, shall be
       deemed received on the next succeeding Banking Day.  The amount of all
       payments received by the Administrative Agent for the account of each
       Lender shall be promptly paid by the Administrative Agent to the
       applicable Lender in immediately available funds.  Should the
       Administrative Agent fail to remit to any Lender any funds actually
       received by the Administrative Agent and due to that Lender on the same
       Banking Day upon which such funds are deemed received by the
       Administrative Agent as set forth above, that Lender shall be entitled to
       recover interest on such funds from the Administrative Agent at a rate
       per
       annum equal to the Federal Funds Rate.   All payments shall be made in
       lawful money of the United States of America.

               (b)  Each payment or prepayment on account of any Committed Loan
       shall be applied pro rata according to the outstanding Committed Advances
       made by each Lender comprising such Committed Loan.  Each payment or
       prepayment of a Competitive Advance shall be applied to the Competitive
       Advance Note held by the Lender which made such Competitive Advance.

               (c)  Each Lender shall use its best efforts to keep a record of
       Advances and Swing Line Loans made by it and payments received by it with
       respect to its Notes and such record shall be presumptive evidence of the
       amounts owing.  Notwithstanding the foregoing sentence, no Lender shall
       be liable to any Party for any failure to keep such a record.

               (d)  Each payment of any amount payable by Borrower or any other
       Party under this Agreement or any other Loan Document shall be made free
       and clear of, and without reduction by reason of, any taxes, assessments
       or other charges imposed by any Governmental Agency, central bank or
       comparable authority (other than taxes on income or gross receipts
       generally applicable


                                                  -46-

       to banks).  To the extent that Borrower is obligated by applicable Laws
       to make any deduction or withholding on account of taxes, assessments or
       other charges imposed by any Governmental Agency from any amount payable
       to any Lender under any Loan Document, Borrower shall (i) make such
       deduction or withholding and pay the same to the relevant Governmental
       Agency and (ii) pay such additional amount to that Lender as is necessary
       to result in that Lender's receiving a net after-tax (or after-assessment
       or after-charge) amount equal to the amount to which that Lender would
       have been entitled under the Loan Document absent such deduction or
       withholding.  If and when receipt of such payment results in an excess
       payment or credit to that Lender on account of such taxes, assessments or
       other charges, that Lender shall refund such excess to Borrower.

               (e)  Each Lender which is organized outside the United States of
       America shall promptly deliver to Borrower and the Administrative Agent a
       completed Internal Revenue Service Form 4224 and any other certificate or
       statement or exemption required by applicable Laws, properly completed
       and
       duly executed by such Lender, to establish that such payment is (1) not
       subject to withholding under the Code because such payment is effectively
       connected with the conduct by such Lender of a trade or business in the
       United States of America or (2) totally exempt from United States tax
       under a provision of an applicable tax treaty.  Unless Borrower and the
       Administrative Agent have received such Form or other documents
       satisfactory to them indicating that payments hereunder or under the
       Notes
       are not subject to United States withholding tax or are subject to such
       tax at a rate reduced by an applicable tax treaty, the Administrative
       Agent shall withhold the taxes from such payment at the applicable statu-
       tory rate in the case of payments to or for any Lender organized under
       the Laws of a jurisdiction outside the United States of America and
       Section 3.11(d) shall not apply thereto.
               -------

     3.12  Funding Sources.  Nothing in this Agreement shall be deemed to
           ---------------
obligate any Lender
to obtain the funds for any Loan, Swing Line Loan or Advance in any particular
place or manner or to constitute a representation by any Lender that it has
obtained or will obtain the funds for any Loan, Swing Line Loan or Advance in
any particular place or manner.

     3.13  Failure to Charge Not Subsequent Waiver.  Any decision by the
           ---------------------------------------
Administrative Agent
or any Lender not to require payment of any interest (including interest arising
                                                      ---------
under Section 3.8), fee, cost or other amount payable under any Loan
             ----


                                                  -47-

Document, or to calculate any amount payable by a particular method, on any
occasion shall in no way limit or be deemed a waiver of the Administrative
Agent's or such Lender's right to require full payment of any interest
(including interest arising under Section 3.8), fee, cost or other amount
 ---------                                ---
payable under any Loan Document,
or to calculate an amount payable by another method, on any other or subsequent
occasion.

     3.14  Administrative Agent's Right to Assume Payments Will be Made by
           ---------------------------------------------------------------
Borrower.  Unless the Administrative Agent shall have been notified by Borrower
- --------
prior to the date
on which any payment to be made by Borrower hereunder is due that Borrower does
not intend to remit such payment, the Administrative Agent may, in its
discretion, assume that Borrower has remitted such payment when so due and the
Administrative Agent may, in its discretion and in reliance upon such
assumption,
make available to each Lender on such payment date an amount equal to such
Lender's share of such assumed payment.  If Borrower has not in fact remitted
such payment to the Administrative Agent, each Lender shall forthwith on demand
repay to the Administrative Agent the amount of such assumed payment made
available to such Lender, together with interest thereon in respect of each day
from and including the date such amount was made available by the Administrative
Agent to such Lender to the date such amount is repaid to the Administrative
Agent at a rate per annum equal to the actual cost to the Administrative Agent
of funding such amount as notified by the Administrative Agent to such Lender.

     3.15  Fee Determination Detail.  The Administrative Agent, and any Lender,
           ------------------------
shall provide
reasonable detail to Borrower regarding the manner in which the amount of any
payment to the Lenders, or that Lender, under Article 3 has been determined.
                                              ---------

     3.16  Survivability   All of Borrower's obligations under Sections 3.6 and
           -------------                                                ---
3.7 shall survive the date on which all Loans and the Swing Line Loans are fully
- ---
paid.

a corporation
duly formed, validly existing and in good standing under the Laws of Nevada.
Borrower is duly qualified to transact business, and is in good standing, in
Nevada and each other jurisdiction in which the conduct of its business or the
ownership or leasing of its Properties makes such qualification or registration
necessary, except where the failure so to qualify or register and
           ------
to be in good standing would not constitute a Material Adverse Effect.  Borrower
has all requisite corporate power and authority to conduct its business, to own
and lease its Properties and to execute and deliver each Loan Document to which
it is a Party and to perform the Obligations.  All outstanding shares of capital
stock of Borrower are duly authorized, validly issued, fully paid, nonassessable
and issued in compliance with all applicable state and federal securities and
other Laws.  Borrower is in compliance with all Laws and other legal
requirements
applicable to its business, has obtained all authorizations, consents,
approvals,
orders, licenses and permits from, and has accomplished all filings, registra-
tions and qualifications with, or obtained exemptions from any of the foregoing
from, any Governmental Agency that are necessary for the transaction of its
business, except where the failure so to comply, file, register, qualify or
          ------
obtain exemptions does not constitute a Material Adverse Effect.

     4.2  Authority; Compliance With Other Agreements and Instruments and
          ---------------------------------------------------------------
Government Regulations.  The execution, delivery and performance by each Party
- ----------------------
of the Loan Documents to

               (d)  Violate any Requirement of Law applicable to such Party;

               (e)  result in a breach of or default under, or would, with the
       giving of notice or the lapse of time or both, constitute a breach of or
       default under, or cause or permit the acceleration of any obligation owed
       under, any indenture or loan or credit agreement or any other Contractual
       Obligation to which such Party is a party or by which such Party or any
       of its Property is bound or affected;

and no such Party is in violation of, or default under, any Requirement of Law
or
Contractual Obligation, or any indenture, loan or credit agreement described in
Section 4.2(e), in any respect that constitutes a Material Adverse Effect.

the Lenders
contained in Section 11.8, no authorization, consent, approval, order, license

required to authorize or permit under applicable Laws the execution, delivery
and performance by each Party of the Loan Documents to which it is a party.

     4.4  Subsidiaries.
          ------------

               (a)  Schedule 4.4 hereto correctly sets forth the names, the form

       aries of Borrower.  Except as described in Schedule 4.4, Borrower does
                                                  ------------
       not own any capital stock or equity interest in any Person.

       and other requirements applicable to its business and has obtained all
       authorizations, consents, approvals, orders, licenses, and permits from,
       and each such Subsidiary has accomplished all filings, registrations, and
       qualifications with, or obtained exemptions from any of the foregoing
       from, any Governmental Agency that are necessary for the transaction of
       its business, except where the failure so to comply, file, register,

     4.5  Financial Statements.  Borrower has furnished to the Lenders (a) the
          --------------------
audited consolidated financial statements of Borrower and its Subsidiaries as at
December 31, 1996 and for the Fiscal Year then ended and (b) the unaudited


                                                  -50-

consolidated financial statements of Borrower and its Subsidiaries as at
September 30, 1997 and for the three Fiscal Quarters then ended.  Such financial
statements fairly present the financial condition and the results of operations
of Borrower and its Subsidiaries as at such dates and for such periods in
accordance with GAAP, consistently applied.

     4.6  No Other Liabilities; No Material Adverse Effect.  Borrower and its
          ------------------------------------------------
Subsidiaries do
not have any material liability or material contingent liability not reflected
or disclosed in the balance sheet or notes thereto described in Section 4.5(b),
                                                                        -----
other than liabilities and contingent liabilities arising in the ordinary course

circumstance has occurred that constitutes a
Material Adverse Effect with respect to Borrower and its Subsidiaries since
September 30, 1997.

          ---------------------------------

     4.8  Intangible Assets.  Borrower owns, or possesses the right to use to
          -----------------
the extent
necessary in its business, all trademarks, trade names, copyrights, patents,
patent rights, computer software, licenses and other Intangible Assets that are
used in the conduct of its business as now operated and which are material to
the
condition (financial or otherwise), business or operations of Borrower, and no
such Intangible Asset, to the best knowledge of Borrower, conflicts with the
valid trademark, trade name, copyright, patent, patent right or Intangible Asset
of any other Person to the extent that such conflict constitutes a Material
Adverse Effect.

     4.9  Governmental Regulation.  Borrower and its Subsidiaries have obtained
          -----------------------
all approvals
necessary under the Public Utility Holding Company Act of 1935 and the Federal
Power Act to permit the execution, delivery and performance of the Obligations
under the Loan Documents.  Neither Borrower nor any of its Subsidiaries is
subject to regulation under the Interstate Commerce Act, the Investment Company
Act of 1940 or to any other Law limiting or regulating its ability to incur
Indebtedness for money borrowed.

     4.10  Litigation.  Except for (a) any matter fully covered (subject to
           ----------   ------
applicable
deductibles and retentions) by insurance for which the insurance carrier has
assumed


                                                  -51-

full responsibility, (b) any matter, or series of related matters, involving a
claim against Borrower or any of its Subsidiaries of less than $5,000,000, (c)
matters described in public documents filed with Governmental Agencies and
previously delivered to the Lenders, and (d) matters set forth in Schedule 4.10,
                                                                           ----
there are no actions, suits, proceedings or investigations pending as to which
Borrower or any of its Subsidiaries have been served or have received notice or,
to the best knowledge of Borrower, threatened against or affecting Borrower or
any of its Subsidiaries or any Property of any of them before any Governmental
Agency.  Except for matters set forth in Schedule 4.10,
         ------                          -------------
there is no reasonable basis, to the best knowledge of Borrower, for any action,
suit, proceeding or investigation against or affecting Borrower or any of its
Subsidiaries or any Property of any of them before any Governmental Agency which
would constitute a Material Adverse Effect.

     4.11  Binding Obligations.  Each of the Loan Documents will, when executed
           -------------------
and delivered

            Commitment and make further Advances and Swing Line Loans, which
            waiver or
            determination shall apply equally to, and shall be binding upon, all

            Docu-
            ments shall be forthwith due and payable, without protest, present-
            ment, notice of dishonor, demand or further notice of any kind, all
            of which are expressly waived by Borrower.

               (c)  Upon the occurrence of any Event of Default, the Lenders and
            the Administrative Agent, or any of them, without notice to or

                                                  -69-

       against Borrower and any other Party and such other rights and remedies
       as are provided by Law or equity.

               (d)  The order and manner in which the Lenders' rights and
       remedies are to be exercised shall be determined by the Majority Lenders
       in their sole discretion, and all payments received by the Administrative
       Agent and the Lenders, or any of them, shall be applied first to the
       costs
       and expenses (including attorneys' fees and disbursements) of the
       Administrative Agent, acting as Administrative Agent, and of the Lenders,
       and thereafter paid pro rata to the Lenders in the same proportions that
       the aggregate Obligations owed to each Lender under the Loan Documents
       bear to the aggregate Obligations owed under the Loan Documents to all
       the
       Lenders, without priority or preference among the Lenders.  Regardless of
       how each Lender may treat payments for the purpose of its own accounting,
       for the purpose of computing Borrower's Obligations hereunder and under
       the Notes, payments shall be applied first, to the costs and
                                            -----
       expenses (including attorneys' fees and disbursements) of the
       Administrative Agent, acting as the Administrative Agent, and then to the
       Lenders, as set forth above, second, to the payment of accrued and unpaid
                                    ------
       interest due under any Loan Documents to and including the date of such
       application
       (ratably, and without duplication, according to the accrued and unpaid
       interest due under
       each of the Loan Documents), and third, to the payment of all other
                                        -----
       amounts
       (including principal and fees) then owing to the Administrative Agent or
       the Lenders under the Loan Documents.  No application of payments will
       cure any Event of Default, or prevent acceleration, or continued
       acceleration, of amounts payable under the Loan Documents, or prevent the

                                       THE ADMINISTRATIVE AGENT
                                       ------------------------

     10.1  Appointment and Authorization.  Each Lender hereby irrevocably
           -----------------------------
appoints and
authorizes the Administrative Agent to take such action as agent on its behalf
and to exercise such powers under the Loan Documents as are delegated to the
Administrative Agent by the terms thereof or are reasonably incidental, as
determined by the Administrative Agent, thereto.  This appointment and
authorization is intended solely for the purpose of facilitating the servicing
of
the Advances and does not constitute appointment of the Administrative Agent as
trustee for any Lender or as representative of any Lender for any other purpose
and, except as specifically set forth in the Loan Documents to the contrary, the
     ------
Administrative
Agent shall take such action and exercise such powers only in an administrative
and
ministerial capacity.  The Administrative Agent is the agent of the Lenders only
and does not assume any agency relationship with Borrower, express or implied.

     10.2  Administrative Agent and Affiliates.  Wells Fargo Bank, National
           -----------------------------------
Association (and
each successor Administrative Agent) has the same rights and powers under the
Loan Documents as any other Lender and may exercise the same as though it was
not
the Administrative Agent, and the term "Lender" or "Lenders" includes Wells
Fargo
Bank, National Association in its individual capacity.  Wells Fargo Bank,
National Association (and each successor Administrative Agent) and its
Affiliates
may accept deposits from, lend money to and generally engage in any kind of
banking, trust or other business with Borrower, any Subsidiary thereof, or any
Affiliate of Borrower or any Subsidiary thereof, as if it was not the
Administrative Agent and without any duty to account therefor to the Lenders.
Wells Fargo Bank, National Association (and each successor Administrative Agent)
need not account to any other Lender for any monies received by it for
reimburse-
ment of its fees, costs and expenses as Administrative Agent hereunder, or for
any monies received by it in its capacity as a Lender hereunder.  Neither the
Arranger, the Swing Line Lender nor the Administrative Agent shall be deemed to
hold a fiduciary relationship with any Lender and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or otherwise exist against the Administrative Agent, the
Swing Line Lender or the Arranger.

     10.3  Proportionate Interest of the Lenders in any Collateral.  The
           -------------------------------------------------------
Administrative Agent,
on behalf of all the Lenders, shall hold in accordance with the Loan Documents
all collateral or interests therein, if any, received or held by the Administra-
tive Agent.  Subject to the Administrative Agent's, the Swing Line Lender's and
the


                                                  -71-

Lender's rights to reimbursement for their costs and expenses hereunder
(including attorneys'
- ----------
fees and disbursements and other professional services) and subject to the
application of payments in accordance with Section 9.2(d), each Lender
(including the Swing Line Lender) shall
                                  ------
have an interest in any collateral or interests therein in the same proportions
that the aggregate Obligations beneficially owed such Lender under the Loan
Documents bear to the aggregate Obligations owed under the Loan Documents to all
the Lenders, without priority or preference among the Lenders.

     10.4  Lenders' Credit Decisions.  Each Lender agrees that it has,
           -------------------------
independently and
without reliance upon the Administrative Agent, the Arranger, the Swing Line
Lender, any other Lender or the directors, officers, agents, employees or
attorneys of the Administrative Agent, the Arranger, the Swing Line Lender or of
any other Lender, and instead in reliance upon information supplied to it by or
on behalf of Borrower and upon such other information as it has deemed
appropriate, made its own independent credit analysis and decision to enter into
this Agreement.  Each Lender also agrees that it shall, independently and
without
reliance upon the Administrative Agent, the Arranger, the Swing Line Lender any
other Lender or the directors, officers, agents, employees or attorneys of the
Administrative Agent, the Arranger, the Swing Line Lender or of any other
Lender,
continue to make its own independent credit analyses and decisions in acting or
not acting under the Loan Documents.

     10.5  Action by Administrative Agent;.
           ------------------------------

               (a)  The Administrative Agent and the Swing Line Lender may
       assume
       that no Default has occurred and is continuing, unless the Administrative
       Agent and the Swing Line Lender have received written notice from
       Borrower
       stating the nature of the Default or has received written notice from a
       Lender stating the nature of the Default and that such Lender considers
       the Default to have occurred and to be continuing.

               (b)  The Administrative Agent has only those obligations under
       the
       Loan Documents as are expressly set forth therein.  The Arranger has no
       obligations under the Loan Documents, although it is an intended third
       party beneficiary of those Sections of this Agreement which refer to the
       Arranger.

               (c)  Except for any obligation expressly set forth in the Loan
                    ------
       Documents and
       as long as the Administrative Agent may assume that no Event of Default
       has occurred and is continuing, the Administrative Agent may, but shall
       not be required to, exercise its discretion to act or not act, except
                                                                      ------
       that the


                                                  -72-

       Administrative Agent shall be required to act or not act upon the
       instruc-
       tions of the Majority Lenders (or of all the Lenders, to the extent
       required by this Agreement) and those instructions shall be binding upon
       the Administrative Agent and all the Lenders, provided that the
                                                     --------
       Administrative Agent
       shall not be required to act or not act if to do so would be contrary to
       any Loan
       Document or to applicable Law or would result, in the reasonable judgment
       of the
       Administrative Agent, in substantial risk of liability to the
       Administrative Agent.

               (d)  If the Administrative Agent has received a written notice
       specified in
       clause (a), the Administrative Agent shall give notice thereof to the
              ---
       Lenders and shall
       act or not act upon the instructions of the Majority Lenders (or of all
       the Lenders, to
       the extent required by Section 11.2), provided that the Administrative
                                      ----   --------
       Agent shall not be required to act or not act if to do so would be
       contrary to any Loan
       Document or to applicable Law or would result, in the reasonable judgment
       of the Administrative Agent, in substantial risk of liability to the
       Administrative Agent, and except that if the Majority Lenders (or all the
                                 ------
       Lenders, if
       required under this Agreement) fail, for five (5) Banking Days after the
       receipt of
       notice from the Administrative Agent, to instruct the Administrative
       Agent, then the
       Administrative Agent, in its sole discretion, may act or not act as it
       deems advisable for the protection of the interests of the Lenders.

               (e)  The Administrative Agent shall have no liability to any
       Lender for acting, or not acting, as instructed by the Majority Lenders
       (or all the Lenders, if required under this Agreement), notwithstanding
       any other provision hereof.

     10.6  Liability of Administrative Agent and Arranger.  Neither the
           ----------------------------------------------
Administrative Agent,
the Arranger, nor any of their respective directors, advisors, officers, agents,
employees or attorneys shall be liable for any action taken or not taken by them
under or in connection with the Loan Documents, except for their own gross
                                                ------
negli-
gence or willful misconduct.  Without limitation on the foregoing, the
Administrative Agent, the Arranger and their respective directors, advisors,
officers, agents, employees and attorneys:

               (a)  May treat the payee of any Note as the holder thereof until
       the Administrative Agent receives written notice of the assignment or
       transfer thereof, in form satisfactory to the Administrative Agent,
       signed
       by the payee, and may treat each Lender as the owner of that Lender's
       interest in the


                                                  -73-

       Obligations for all purposes of this Agreement until the Administrative
       Agent receives written notice of the assignment or transfer thereof, in
       form satisfactory to the Administrative Agent, signed by that Lender.

               (b)  May consult with legal counsel (including in-house legal
                                                    ---------
       counsel),
       accountants (including in-house accountants) and other professionals or
                    ---------
       experts
       selected by it, or with legal counsel, accountants or other professionals
       or experts for Borrower and/or its Subsidiaries or the Lenders, and shall
       not be liable for any action taken or not taken by it in good faith in
       accordance with any advice of such legal counsel, accountants or other
       professionals or experts.

               (c)  Shall not be responsible to any Lender for any statement,
       warranty or representation made in any of the Loan Documents or in any
       notice,
       certificate, report, request or other statement (written or oral) given
       or made in
       connection with any of the Loan Documents, unless such statement,
                                                  ------
       warranty or representation is an independent statement, warranty or
       representation of the
       Administrative Agent which is not based upon information received by the
       Administrative
       Agent from Borrower or any other Person not affiliated with the
       Administrative Agent.

               (d)  Except to the extent expressly set forth in the Loan Docu-
                    ------
       ments, shall
       have no duty to ask or inquire as to the performance or observance by
       Borrower or its Subsidiaries of any of the terms, conditions or covenants
       of any of the Loan Documents or to inspect any collateral or the
       Property,
       books or records of Borrower or its Subsidiaries.

               (e)  Will not be responsible to any Lender for the due execution,
       legality, validity, enforceability, genuineness, effectiveness,
       sufficiency or value of any Loan Document, any other instrument or

       furnished pursuant thereto or in connection therewith, or any collateral.

               (f)  Will not incur any liability by acting or not acting in
       reliance upon any Loan Document, notice, consent, certificate, statement,
       request or other instrument or writing believed by it to be genuine and
       signed or sent by the proper party or parties.

               (g)  Will not incur any liability for any arithmetical error in
       computing any amount paid or payable by the Borrower or any Subsidiary


                                                  -74-

       or Affiliate thereof or paid or payable to or received or receivable from
       any Lender
       under any Loan Document, including, without limitation, principal,
                                ---------
       interest, commitment
       fees, Advances, Swing Line Loans and other amounts; provided that,
                                                           --------
       promptly upon
       discovery of such an error in computation, the Administrative Agent, the
       Lenders and (to the extent applicable) Borrower and/or its Subsidiaries
       or
       Affiliates shall make such adjustments as are necessary to correct such
       error and to restore the parties to the position that they would have
       occupied had the error not occurred.

     10.7  Indemnification.  Each Lender and the Swing Line Lender shall,
           ---------------
ratably in accordance
with their respective portions of the Commitment, indemnify and hold the
Administrative Agent, and the Arranger and their respective directors, advisors,
officers, agents, employees and attorneys harmless against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever (including,
                                                                   ---------
without limitation, attorneys' fees and disbursements) that may be imposed on,
incurred by or asserted against it or them in any way relating to or arising out
of the Loan Documents (other than losses incurred by reason of the failure of
Borrower to pay the indebtedness represented by the Notes and interest thereon
or to pay the fees described in Sections 3.2 and 3.3) or any action taken or not
                                         ---     ---
taken by Wells Fargo Bank, National Association
as Administrative Agent thereunder, except such as result from their own gross
                                    ------
negligence or
willful misconduct.  Without limitation on the foregoing, each Lender shall
reimburse the  Administrative Agent and the Arranger upon demand for that
Lender's ratable share of any cost or expense incurred by the Administrative
Agent or the Arranger in connection with the negotiation, preparation,
execution, delivery, amendment, waiver, restructuring, reorganization (including
                                                                       ---------
a bankruptcy reorganization), enforcement or attempted enforcement of the Loan
Documents, to the extent that Borrower or any other Party is required by
Section 11.3 to pay that cost or expense but fails to do so upon demand.
        ----

     10.8  Successor Administrative Agent.  If the Administrative Agent
           ------------------------------
determines that for it
to continue as Administrative Agent would result in a conflict of interest
affecting the Administrative Agent, or would create an unacceptable risk of
significant liability of the Administrative Agent to a third party, or would
otherwise be inadvisable under prevailing standards of banking prudence, it may
resign as such at any time upon prior written notice to Borrower and the
Lenders,
to be effective upon a successor's acceptance of appointment as Administrative
Agent.  The Administrative Agent may also resign as such absent such a
determination by it with the consent of Borrower, which shall not be
unreasonably
withheld, to be likewise effective.  The Majority


                                                  -75-

Lenders at any time may remove the Administrative Agent by written notice to
that
effect to be effective on such date as the Majority Lenders designate.  In
either
event:  (a) the Majority Lenders shall appoint a successor Administrative Agent,
who must be from among the Lenders, provided that any resigning Administrative
                                    --------
Agent shall be entitled to appoint a successor Administrative Agent from among
the Lenders, subject to acceptance of appointment by that successor
Administrative Agent, if the Majority Lenders have not appointed a successor
Administrative Agent within thirty (30) days after the date the resigning
Administrative Agent gave notice of resignation; (b) upon a
successor's acceptance of appointment as Administrative Agent, the successor
will
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the resigning Administrative Agent or the removed Administrative
Agent; and (c) upon the effectiveness of any resignation or removal, the
resigning Administrative Agent or the removed Administrative Agent thereupon
will
be discharged from its duties and obligations thereafter arising under the Loan
Documents other than obligations arising as a result of any action or inaction
of
the resigning Administrative Agent or the removed Administrative Agent prior to
the effectiveness of such resignation or removal.

     10.9 No Obligations of Borrower.  Nothing contained in this Article 10
          --------------------------                             ----------
shall be deemed to
impose upon Borrower any obligation in respect of the due and punctual
performance by the Administrative Agent of its obligations to the Lenders under
any provision of this Agreement, and Borrower shall have no liability to the
Administrative Agent or any of the Lenders in respect of any failure by the
Administrative Agent or any Lender to perform any of its obligations to the
Administrative Agent or the Lenders under this Agreement.  Without limiting the
generality of the foregoing, where any provision of this Agreement relating to
the payment of any amounts due and owing under the Loan Documents provides that
such payments shall be made by Borrower to the Administrative Agent for the
account of the Lenders, Borrower's obligations to the Lenders in respect of such
payments shall be deemed to be satisfied upon the making of such payments to the
Administrative Agent in the manner provided by this Agreement.

     10.10  The Swing Line.  It is intended that each Lender and the Swing Line
            --------------
Lender shall
have a proportionate credit risk with respect to the credit facilities extended
pursuant to this Agreement (other than any Competitive Advances) equal for each
                            -----
Lender to the proportion which (a) the amount of that Lender's Pro Rata Share of
the Main Commitment plus in the case of the Swing Line Lender, the Swing Line
                    ----
Commitment, bears to (b)
the Commitment.  To the extent, if any, that the aggregate principal amount of
the Obligations (other than any Competitive Advances) owed to
                 -----

                                                  -76-

any Lender are ratably in excess of its proportionate share of the Obligations
(determined in accordance with the foregoing sentence), then each Lender shall
be
deemed to have purchased a ratable unfunded participation in the excess such
Obligations owed to that Lender.  Upon the occurrence of an Event of Default,
each Lender and the Swing Line Lender agree that (x) the amount of the Main
Commitment shall automatically be increased by the amount of the Swing Line
Commitment and the Swing Line Commitment terminated, (y) each Lender (or, in the
appropriate case, the Swing Line Lender) shall pay to the Swing Line Lender (or,
in the appropriate case, to the Lenders) such amounts as are necessary to result
in the Obligations (other than any outstanding Competitive Advances) owed to
                    -----
each Lender being
ratably equal, provided however, that in no event shall any Lender be obligated
               --------
to make Advances
to Borrower which are greater than its pro rata share of the total Commitment.

                                              -------------

     11.1  Cumulative Remedies; No Waiver.  The rights, powers, privileges and
           ------------------------------
remedies of the
Administrative Agent and the Lenders provided herein or in any Note or other
Loan
Document are cumulative and not exclusive of any right, power, privilege or
remedy provided by Law or equity.  No failure or delay on the part of the
Administrative Agent or any Lender in exercising any right, power, privilege or
remedy may be, or may be deemed to be, a waiver thereof; nor may any single or
partial exercise of any right, power, privilege or remedy preclude any other or
further exercise of the same or any other right, power, privilege or remedy.
The
terms and conditions of Article 8 hereof are inserted for the sole benefit of
                        ---------
the Administrative
Agent and the Lenders; the same may be waived in whole or in part, with or
without terms or
conditions, in respect of any Loan without prejudicing the Administrative
Agent's
or the Lenders' rights to assert them in whole or in part in respect of any
other
Loan.

     11.2  Amendments; Consents.  No amendment, modification, supplement,
           --------------------
extension,
termination or waiver of any provision of this Agreement or any other Loan
Document, no approval or consent thereunder, and no consent to any departure by
the Borrower or any other Party therefrom, may in any event be effective unless
in writing signed by the Administrative Agent with the approval in writing of
the
Majority Lenders and Borrower, and then only in the specific instance and for
the
specific purpose given; and, without the approval in writing of all the Lenders,
no amendment, modification, supplement, termination, waiver or consent may be
effective:

               (a)  To amend or modify the principal of, or the amount of
       principal, or the rate of interest payable on, any Note, or the amount of
       the Main Commitment, the Swing Line Commitment or the Commitment or of
       any
       facility fee payable to any Lender, or any other fee or amount payable to
       any Lender under the Loan Documents;

               (b)  To postpone any date fixed for any payment of principal of,
       prepayment of principal of or any installment of interest on, any Note or
       any installment of any facility fee, or any other fee or amount payable
       to
       any Lender under the Loan Documents, or to extend the term of the Commit-
       ment, or to release any collateral for the Obligations;


                                                  -78-

      ----------    ----------------       ---------------------           ---
      or this Section; or

          (d)  To amend or modify any provision of this Agreement that expressly
       requires the consent or approval of all the Lenders.

Any amendment, modification, supplement, termination, waiver or consent pursuant
to this Section shall apply equally to, and shall be binding upon, all the
Lenders and the Administrative Agent.

     11.3  Costs, Expenses and Taxes.  Borrower shall pay on demand the
           -------------------------
reasonable costs and
expenses of the Administrative Agent (including the fees and expenses of counsel
to the Administrative Agent) in connection with the negotiation, preparation,
execution and delivery of the Loan Documents, and of the Administrative Agent,
the Swing Line Lender and the Lenders in connection with any amendment, waiver,
refinancing, restructuring, reorganization (including a
                                            ---------
bankruptcy reorganization), enforcement or attempted enforcement of the Loan
Documents, and any matter related thereto, including, without limitation, filing
                                           ---------

the reasonable fees and out-of-pocket expenses of any legal counsel, independent

Subsidiary thereof.
Borrower shall pay any and all documentary and other taxes (other than income or

indemnify the Administrative Agent and the Lenders from and against any and all
loss, liability or legal or other expense with respect to or resulting from any
delay in paying or failure to pay any tax, cost, expense, fee or charge or that
any of them may suffer or incur by reason of the failure of any Party to perform
any of its Obligations.  Any amount payable to the Administrative Agent or any
Lender under this Section shall bear interest from the second Banking Day
following the date of demand for payment at the Default Rate.


                                                  -79-

     11.4  Nature of Lenders' Obligations.  The obligations of the Lenders
           ------------------------------
hereunder are
several and not joint or joint and several.  Nothing contained in this Agreement
or any other Loan Document and no action taken by the Administrative Agent or
the
Lenders or any of them pursuant hereto or thereto may, or may be deemed to, make
the Lenders a partnership, an association, a joint venture or other entity,
either among themselves or with the Borrower or any Affiliate of the Borrower.
Each Lender's several obligation to make Committed Advances is conditioned upon
the performance by all other Lenders of their obligations to make similar
Committed Advances. A default by any Lender will not increase the amount of the
Commitment attributable to any other Lender, and any Lender not in default may,
if it desires, assume in such proportion as the nondefaulting Lenders agree the
obligations of any Lender in default, but is not obligated to do so.

     11.5  Survival of Representations and Warranties.  All representations and
           ------------------------------------------
warranties contained herein or in any other Loan Document, or in any certificate
or other
writing delivered by or on behalf of any one or more of the Parties to any Loan
Document, will survive the making of the Advances hereunder and the execution
and
delivery of the Notes, and have been or will be relied upon by the
Administrative
Agent and each Lender, notwithstanding any investigation made by the
Administrative Agent or any Lender or on their behalf.

     11.6   Notices.  Except as otherwise expressly provided in any Loan
            -------   ------
Document, all notices,
requests, demands, directions and other communications provided for hereunder or
under any other Loan Document must be in writing and must be mailed, telecopied,
or personally delivered to the appropriate party at the address set forth on the
signature pages of this Agreement or other applicable Loan Document or, as to
any
party to any Loan Document, at any other address as may be designated by it in a
written notice sent to all other parties to such Loan Document in accordance
with
this Section.  Except as otherwise expressly provided in any Loan Document, if
               ------
any notice, request, demand, direction or other communication required or
permitted by any Loan Document is given by mail it will be effective on the
earlier of receipt or the third calendar day after deposit in the United States
mail with first class or airmail postage prepaid; if given by telex or
telecopier, when sent; or if given by personal delivery, when delivered.

     11.7  Execution of Loan Documents; Counterparts.  Unless the Administrative
           -----------------------------------------
Agent
otherwise specifies with respect to any Loan Document, this Agreement and any
other Loan Document may be executed in any number of counterparts and any party
hereto or thereto may execute any counterpart, each of which when executed and


                                                  -80-

delivered will be deemed to be an original and all of which counterparts of this
Agreement or any other Loan Document, as the case may be, when taken together
will be deemed to be but one and the same instrument.  The execution of this
Agreement or any other Loan Document by any party hereto or thereto will not
become effective until counterparts hereof or thereof, as the case may be, have
been executed by all the parties hereto or thereto.

     11.8  Binding Effect; Assignment
           --------------------------

               (a)  This Agreement and the other Loan Documents to which
       Borrower is a Party
       will be binding upon and inure to the benefit of Borrower, the
       Administrative Agent, each
       of the Lenders, and their respective successors and assigns, except that
                                                                    ------
       Borrower may not
       assign its rights hereunder or thereunder or any interest herein
       or therein
       without the prior written consent of all the Lenders.  Each Lender
       represents that
       it is not acquiring its Notes with a view to the distribution thereof
       within the meaning
       of the Securities Act of 1933, as   amended (subject to any requirement
       that disposition
       of such Notes must be within the control of such Lender).  Any Lender may
       at any time
       pledge its Notes or any other instrument evidencing its rights as a
       Lender under this
       Agreement to a Federal Reserve Bank, but no such pledge shall release
       that
       Lender from its obligations hereunder or grant to such Federal Reserve
       Bank the rights of a Lender hereunder absent foreclosure of such pledge.

               (b)  From time to time following the Closing Date, each Lender
       may assign to one
       or more Eligible Assignees all or any portion of its Pro Rata Share of
       the Main
       Commitment; provided that (i) such Eligible Assignee, if not then a
                   --------
       Lender, shall be
       reasonably acceptable to the Administrative Agent, (ii) such assignment
       shall be evidenced by a Commitment Assignment and Acceptance, a copy of
       which shall be furnished to the Administrative Agent for registration as
       hereinbelow provided, (iii) the assignment shall not assign a Pro Rata
       Share of the Main Commitment equivalent to less than $5,000,000 unless
       the
       assigning Lender thereby assigns its entire Pro Rata Share and (iv) the
       effective date of any such assignment shall be as specified in the
       Commitment Assignment and Acceptance, but without the consent of the
       Administrative Agent not earlier than the date which is ten (10) Banking
       Days after the date the Administrative Agent has registered the
       Commitment
       Assignment and Acceptance in the register kept for that purpose by the
       Administrative Agent described below.  Upon the effective date of such
       Commitment Assignment and Acceptance, the Eligible Assignee named therein
       shall be a Lender for all purposes of this


                                                  -81-

       Agreement, with the Pro Rata Share of the Main Commitment therein set
       forth and, to the extent of such Pro Rata Share, the assigning Lender
       shall be released from its obligations under this Agreement.  Borrower
       agrees that it shall execute and deliver (against delivery by the
       assigning Lender to Borrower of its Notes) to such assignee Lender, Note
       evidencing that assignee Lender's Pro Rata Share of the Main Commitment
       and any Competitive Advances to be made by that Lender, and to the
       assigning Lender, a Note evidencing the remaining balance Pro Rata Share
       retained by the assigning Lender.

               (c)  By executing and delivering a Commitment Assignment and
       Acceptance, the Eligible Assignee thereunder acknowledges and agrees
       that:
       (i) other than the representation and warranty that it is the legal and
       beneficial owner of the Pro Rata Share of the Main Commitment being
       assigned thereby free and clear of any adverse claim, the assigning
       Lender
       has made no representation or warranty and assumes no responsibility with
       respect to any statements, warranties or representations made in or in
       connection with this Agreement or the execution, legality, validity,
       enforceability, genuineness or sufficiency of this Agreement or any other
       Loan Document; (ii) the assigning Lender has made no representation or
       warranty and assumes no responsibility with respect to the financial
       condition of Borrower or the performance by Borrower of the Obligations;
       (iii) it has received a copy of this Agreement, together with copies of
       the most recent financial statements delivered pursuant to Section 7.1
                                                                          ---
       and such
       other documents and information as it has deemed appropriate to make its
       own credit analysis and decision to enter into such Commitment Assignment
       and Acceptance; (iv) it will, independently and without reliance upon the
       Administrative Agent or any Lender and based on such documents and
       information as it shall deem appropriate at the time, continue to make
       its
       own credit decisions in taking or not taking action under this Agreement;
       (v) it appoints and authorizes the Administrative Agent to take such
       action and to exercise such powers under this Agreement as are delegated
       to the Administrative Agent by this Agreement; and (vi) it will perform
       in
       accordance with their terms all of the obligations which by the terms of
       this Agreement are required to be performed by it as a Lender.

               (d)  The Administrative Agent shall maintain at the
       Administrative
       Agent's Office a copy of each Commitment Assignment and Acceptance
       delivered to it and a register for recordation of the names and addresses
       of the Lenders and their respective Pro Rata Shares of the Main
       Commitment.  Upon receipt of a completed Commitment Assignment and
       Acceptance executed by


                                                  -82-

       any Lender and an Eligible Assignee, and upon receipt of a registration
       fee of $3,000 from such Eligible Assignee, Administrative Agent shall
       record the making of the assignments contemplated in such Commitment
       Assignment and Acceptance in such register.  The entries in such register
       shall be conclusive in the absence of manifest error, and the Borrower,
       the Administrative Agent and the Lenders may treat each Person whose name
       is recorded in the register as a Lender hereunder for all purposes of
       this
       Agreement.

               (e)  Each Lender may from time to time without the consent of
       Borrower or the
       Administrative Agent grant participations to one or more banks or other
       financial
       institutions in a portion of its Pro Rata Share of the Main Commitment;
       provided,
- -
       --------
       however, that (i) such Lender's obligations under this Agreement shall
       -------
       remain
       unchanged, (ii) such Lender shall remain solely responsible to the other
       parties hereto
       for the performance of such obligations, (iii) the participating banks or
       other financial
       institutions shall not be a Lender hereunder for any purpose except, if
                                                                    ------
       the participation
       agreement so provides, for the purposes of Sections 3.6, 3.7 and 11.11
                                                           ---  ---     -----
       but only to the extent that the cost of such benefits to Borrower does
       not
       exceed the cost which Borrower would have incurred in respect of such
       Lender absent the participation, (iv) Borrower, the Administrative Agent
       and the other Lenders shall continue to deal solely and directly with
       such
       Lender in connection with such Lender's rights and obligations under this
       Agreement, (v) the consent of the holder of such participation interest
       shall not be required for amendments or waivers of provisions of the Loan
       Documents other than those which (A) increase the monetary amount of any
                 ----- ----
       of the Commitment, (B) extend the Maturity Date or any other date upon
       which any
       payment of money is due to the Lenders or (C) reduce the rate of interest
       on the Notes, or any fee or any other monetary amount payable to the
       Lenders and (vi) such Lender shall notify the Administrative Agent in
       writing of the identity of the participant and the amount of the
       participation interest within five Banking Days after the date granted.

               (f)  The Swing Line Lender may assign the entire Swing Line
       Commitment subject to the conditions and in the manner applicable to
       assignments of portions of the Main Commitment set forth above.

               (g)  Notwithstanding anything to the contrary contained herein,
       any Lender (a "Granting Lender") may grant to a special purpose funding
       vehicle (an "SPC") of such Granting Lender, identified as such in writing
       from time to time by the Granting Lender to the Administrative Agent and
       Borrower,


                                                  -83-

       the option to provide to Borrower all or any part of any Loan that such
       Granting Lender
       would otherwise be obligated to make to the Borrower pursuant to Sections
       2.1(a) or 2.2,
       -----     ---
       provided that (i) nothing herein shall constitute a commitment to make
       --------
       any Loan by
       any SPC and (ii) if an SPC elects not to exercise such option or
       otherwise
       fails to provide all or any part of such Loan, the Granting Lender shall
       be obligated to make such Loan pursuant to the terms hereof.  The making
       of a Loan by an SPC shall utilize the Pro Rata Share of the Main
       Commitment of the Granting Lender to the same extent, and as if, such
       Loan
       were made by the Granting Lender.  Each party hereby agrees that no SPC
       shall be liable for any indemnity or similar payment obligation under
       this
       Agreement (all liability for which shall remain with the related Granting
       Lender).  In furtherance of the foregoing, each party hereto agrees
       (which
       agreement shall survive the termination of this Agreement) that, prior to
       the date that is one year and one day after the payment in full of all
       outstanding senior indebtedness of any SPC, it will not institute
       against,
       or join any other Person in instituting against, such SPC any proceeding
       under any Debtor Relief Law, provided that the Granting Lender for each
                                    --------
       SPC hereby agrees to indemnify, save and hold harmless each other party
       hereto
       for any loss, cost, damage and expense arising out of its inability to
       institute any such proceeding against the SPC related to such Granting
       Lender.  In addition, notwithstanding anything to the contrary contained
       in this Section 11.8, any SPC may (i) with notice to, but without the
                       ----
       consent of,
       Borrower or the Administrative Agent and without paying any processing
       fee therefor,
       assign all or a portion of its interests in any Loans to its Granting
       Lender or to any financial institutions providing liquidity and/or credit
       facilities to or for the account of such SPC to fund the Loans made by
       such SPC or to support the securities (if any) issued by such SPC to fund
       such Loans (but nothing contained herein shall be construed in derogation
       of the obligation of the Granting Lender to make Loans hereunder),
       provided that neither
       --------
       the consent of the SPC or of any such assignee shall be required for
       amend-
       ments or waivers of provisions of the Loan Documents except for those
       amendments or waivers for which the consent of participants is required
       under Section 11.8(e)(v), and (ii) disclose on a confidential basis any
                     ---------
       non-public
       information relating to its Loans to any rating agency, commercial paper
       dealer or
       provider of a surety, guarantee or credit or liquidity enhancement to
       such SPC.

     11.9  Setoff Rights.  If an Event of Default has occurred and is
           -------------
continuing, the
Administrative Agent or any Lender (but only with the consent of the Majority
Lenders) may, to the extent permitted by applicable Laws, exercise its rights
under


                                                  -84-

applicable Laws to setoff and apply any funds in any deposit account maintained
with it by Borrower and/or any Property of Borrower in its possession against
the
Obligations.

     11.10  Sharing of Setoffs.  Each Lender severally agrees that if it,
            ------------------
through the exercise
of any right of setoff, banker's lien or counterclaim against Borrower, or
otherwise, receives payment, through any means, of the Obligations held by it
that is in excess of that Lender's Pro Rata Share of such payment, then:  (a)
The
Lender exercising the right of setoff, banker's lien or counterclaim or
otherwise
receiving such payment shall purchase, and shall be deemed to have
simultaneously
purchased, from the other Lender a participation in the Obligations held by the
other Lender and shall pay to the other Lender a purchase price in an amount so
that the share of the Obligations held by each Lender after the exercise of the
right of setoff, banker's lien or counterclaim or receipt of payment shall be in
the same proportion that existed prior to the exercise of the right of setoff,
banker's lien or counterclaim or receipt of payment; and (b) Such other
adjustments and purchases of participations shall be made from time to time as
shall be equitable to ensure that all of the Lenders share any payment obtained
in respect of the Obligations ratably in accordance with each Lender's share of
the Obligations immediately prior to, and without taking into account, the
payment; provided that, if all or any portion of a disproportionate payment
         --------
obtained as a result
of the exercise of the right of setoff, banker's lien, counterclaim or otherwise
is thereafter recovered from the purchasing Lender by Borrower or any Person
claiming through or succeeding to the rights of Borrower, the purchase of a
participation shall be rescinded and the
purchase price thereof shall be restored to the extent of the recovery, but
without interest.  Each Lender that purchases a participation in the Obligations
pursuant to this Section shall from and after the purchase have the right to
give
all notices, requests, demands, directions and other communications under this
Agreement with respect to the portion of the Obligations purchased to the same
extent as though the purchasing Lender were the original owner of the
Obligations
purchased.  Borrower expressly consents to the foregoing arrangements and agrees
that any Lender holding a participation in an Obligation so purchased may
exercise any and all rights of setoff, banker's lien or counterclaim with
respect
to the participation as fully as if the Lender were the original owner of the
Obligation purchased; provided, however, that each Lender agrees that it shall
                      --------
not exercise any right of setoff, banker's lien or counterclaim without first
obtaining the consent of the Majority Lenders.

     11.11  Indemnity by Borrower.  Borrower agrees to indemnify, save and hold
            ---------------------
harmless the
Administrative Agent, the Arranger, the Swing Line Lender and each Lender and
their directors, officers, agents, advisors, attorneys and employees (collec-


                                                  -85-

tively the "Indemnitees") from and against:  (a) Any and all claims, demands,
            -----------
actions or causes
of action that are asserted against any Indemnitee by any Person (other than the
Administrative Agent, the Arranger, the Swing Line Lender or a Lender) if the
claim, demand, action or cause of action directly or indirectly relates to a
claim, demand, action or cause of action that such Person has or asserts against
Borrower, any Affiliate of Borrower or any officer, director or shareholder of
Borrower; (b) Any and all claims, demands, actions or causes of action that are
asserted against any Indemnitee if the claim, demand, action or cause of action
arises out of or relates to the relationship between Borrower and the Lenders
under any of the Loan Documents or the transactions contemplated thereby; (c)
Any
and all administrative or investigative proceedings by any Governmental Agency
arising out of or related to any claim, demand, action or cause of action
described in clauses (a) or (b) above; and (d) Any and all liabilities, losses,
costs or expenses (including attorneys' fees and disbursements and other pro-
                   ---------
fessional services) that any Indemnitee suffers or incurs as a result of the
assertion of any of the foregoing; provided that no Indemnitee shall be entitled
                                   --------
to indemnification for
any loss caused by its own gross negligence or willful misconduct.  Each
Indemnitee is authorized to employ counsel of its own choosing in enforcing its
rights hereunder and in defending against any claim, demand, action, cause of
action or administrative or
investigative proceeding covered by this Section; provided that each Indemnitee
                                                  --------
shall endeavor, in connection with any matter covered by this Section which also
involves other Indemnitees, to use reasonable efforts to avoid unnecessary
duplication of effort by counsel for all Indemnitees.  Any obligation or
liability of Borrower to any Indemnitee under this Section shall be and hereby
is covered and secured by the Loan Documents and the Collateral, and shall
survive the expiration or termination of this Agreement and the repayment of all
Loans and Swing Line Loans and the payment and performance of all other
Obligations owed to the Lenders.

     11.12  Nonliability of the Lenders.  Borrower acknowledges and agrees that:
            ---------------------------

               (a)  Any inspections of any Property of Borrower made by or
       through the Administrative Agent, the Arranger, the Swing Line Lender or
       the Lenders are for purposes of administration of the Loan Documents only
       and Borrower is not entitled to rely upon the same;

               (b)  By accepting or approving anything required to be observed,
       performed, fulfilled or given to the Administrative Agent or the Lenders
       pursuant to the Loan Documents, neither the Administrative Agent nor the
       Lenders shall be deemed to have warranted or represented the sufficiency,


                                                  -86-

       legality, effectiveness or legal effect of the same, or of any term,
       provision or condition thereof, and such acceptance or approval thereof
       shall not constitute a warranty or representation to anyone with respect
       thereto by the Administrative Agent or the Lenders;

               (c)  The relationship between Borrower and the Administrative
       Agent, the Arranger, the Swing Line Lender and the Lenders is, and shall
       at all times remain, solely that of a borrower and lenders; neither the
       Administrative Agent, the Arranger, the Swing Line Lender nor the Lenders
       shall under any circumstance be construed to be partners or joint
       venturers of Borrower or its Affiliates; neither the Administrative
       Agent,
       the Arranger, the Swing Line Lender nor the Lenders shall under any
       circumstance be deemed to be in a relationship of confidence or trust or
       a fiduciary relationship with Borrower or its Affiliates, or to owe any
       fiduciary duty to Borrower or its Affiliates; neither the Administrative
       Agent, the Arranger, the Swing Line Lender nor the Lenders undertake or
       assume any responsibility or duty to Borrower or its Affiliates to
       select,
       review, inspect, supervise, pass judgment upon or inform Borrower or its
       Affiliates of any matter in connection with their Property or the
       operations of Borrower or its Affiliates; Borrower and its Affiliates
       shall rely entirely upon their own judgment with respect to such matters;
       and any review, inspection, supervision, exercise of judgment or supply
       of information undertaken or assumed by the Administrative Agent, the
       Arranger, the Swing Line Lender or the Lenders in connection with such
       matters is solely for the protection of the Administrative Agent, the
       Arranger, the Swing Line Lender and the Lenders and neither Borrower nor
       any other Person is entitled to rely thereon; and

               (d)  The Administrative Agent, the Arranger, the Swing Line
       Lender
       and the Lenders shall not be responsible or liable to any Person for any
       loss, damage, liability or claim of any kind relating to injury or death
       to Persons or damage to Property caused by the actions, inaction or
       negligence of Borrower and/or its Affiliates and Borrower hereby
       indemnifies and holds the Administrative Agent, the Arranger, the Swing
       Line Lender and the Lenders harmless from any such loss, damage,
       liability or claim.

     11.13  No Third Parties Benefited.  This Agreement is made for the purpose
            --------------------------
of defining and
setting forth certain obligations, rights and duties of Borrower, the
Administrative Agent, the Arranger, the Swing Line Lender, the Issuing Bank and
the Lenders in connection with the Loans, the Swing Line Loans and Advances, and
the Letters of Credit and is made for the sole benefit of Borrower, the
Administrative Agent, the Arranger, the Swing Line Lender and the Lenders, and

control and govern; provided that the inclusion of supplemental rights or
                    --------
remedies in favor of the Administrative Agent or the Lenders in any other Loan
Document shall not be deemed a conflict with this Agreement.  Each Loan Document
was drafted with the joint participation of the respective parties thereto and
shall be construed neither against nor in favor of any party, but rather in
accordance with the fair meaning thereof.

     11.17  Governing Law.  Except to the extent otherwise expressly provided

affecting the remaining provisions or the operation, enforceability or validity
of that provision as to any other party or in any other jurisdiction, and to
this
end the provisions of all Loan Documents are declared to be severable.

     11.19  Independent Covenants.  Each covenant in Articles 5, 6 and 7 is
            ---------------------                    -------- -  -     -
independent of the
other covenants in those Articles; the breach of any such covenant shall not be
excused by the fact that the circumstances underlying such breach would be
permitted by another such covenant.

            --------
other Loan
