<PAGE>

          SECTION 2.1.  Commitments.  On the terms and subject to the conditions
                        -----------
of this Agreement, each Lender severally agrees to make, Convert and Continue
Loans pursuant to such Lender's Commitment as provided in this Article 2.

            2.1.1.  Commitments. From time to time on any Business Day occurring
                    -----------
prior to the related Commitment Termination Date, each Lender severally agrees
to make loans (each, a "Loan") to the Borrower equal to such Lender's Percentage
                        ----
of the Borrowing of Loans requested by the Borrower to be made on such day. The
commitment of each Lender described in this Section 2.1.1 is herein referred to
                                            -------------
as its "Commitment."  The Borrower may from time to time borrow, prepay, in
        ----------
whole or in part, and reborrow Loans. Commitments shall terminate automatically
on the related Commitment Termination Date.

            2.1.2.  Lenders Not Required To Make Loans.  No Lender shall be
                    ----------------------------------
required to make any Loan if, after giving effect thereto:

          (a) the aggregate outstanding principal amount of all Loans of all
     Lenders would exceed the Total Commitment Amount; or

          (b) the aggregate outstanding principal amount of all Loans of such
     Lender would exceed such Lender's Percentage of the Total Commitment
     Amount.

          SECTION 2.2.  Reduction of the Total Commitment Amount.  The Borrower
                        ----------------------------------------
may, from time to time on any Business Day occurring after the Effective Date,
voluntarily reduce the Total Commitment Amount without premium or penalty
(subject, however, to Section 4.5); provided, however, that all such reductions
                      -----------   --------  -------
shall require at least three Business Days' prior notice to the Administrative
Agent and be permanent, and any partial reduction of the Total Commitment Amount
shall be in a minimum amount of $10,000,000 and in an integral multiple of
$1,000,000 in excess thereof; and, provided, further, that the Total Commitment
                                   --------  -------
Amount may not be reduced to an amount less than the aggregate amount of
outstanding Loans.

          SECTION 2.3.  Borrowing Procedure.  By delivering a Borrowing Request
                        -------------------
to the Administrative Agent (i) in the case of LIBO Rate Loans, at or before
11:00 A.M., San Francisco time, not less than three Business Days' prior to the
date on which the requested Borrowing is to be made, and (ii) in the case of
Base Rate Loans, at or before 10:00 A.M., San Francisco time, on the Business
Day on which the requested Borrowing is to be made, the Borrower may from time
to time irrevocably request a Borrowing of Loans be made in minimum amounts of
$10,000,000 or in the unused amount of the Total Commitment Amount. Upon receipt
of any such notice from the Borrower, the Administrative Agent shall promptly
notify each Lender thereof. On the terms and subject to the conditions of this
Agreement, each Borrowing shall be comprised of the same type of Loans, and
shall be made on the Business Day specified in such Borrowing Request. On or
before 11:00 A.M., San Francisco time, on the Business Day such Loans are to be
made, each Lender shall deposit with the Administrative Agent Same Day Funds in
an amount equal to such Lender's Percentage of the requested Borrowing. Such
deposit will be made to an account which the Administrative Agent shall specify
from time to time by notice to the Lenders. To the extent funds are received
from the Lenders, the Administrative Agent shall make such funds available to
the Borrower by wire transfer to the accounts the Borrower shall

                                      -14-
<PAGE>

have specified in its Borrowing Request. No Lender's obligation to make any Loan
shall be affected by any other Lender's failure to make any Loan.

          SECTION 2.4.  Continuation and Conversion Elections.  The Borrower may
                        -------------------------------------
from time to time irrevocably elect that all, or any portion in an aggregate
minimum amount of $10,000,000 and an integral multiple of $1,000,000 in excess
thereof, of (i) any Base Rate Loan be Converted into a LIBO Rate Loan, or (ii)
any LIBO Rate Loan be Continued as a LIBO Rate Loans, in each case by delivering
a Continuation/Conversion Notice to the Administrative Agent at or before 11:00
A.M., San Francisco time, not less than three Business Days' prior to the
requested Conversion or Continuation. In the absence of delivery of a
Continuation/Conversion Notice with respect to any LIBO Rate Loan, such LIBO
Rate Loan shall automatically be Continued as a one month LIBO Rate Loan;
provided, however, that (i) each such Conversion or Continuation shall be pro
--------  -------
rated among the applicable outstanding Loans of all Lenders, (ii) a LIBO Rate
Loan may not be converted at any time other than the last day of the Interest
Period applicable thereto, (iii) no portion of the outstanding principal amount
of any Loans may be Continued as, or be Converted into, LIBO Rate Loans when any
Default or Event of Default under Section 8.1.1 has occurred and is continuing,
                                  -------------
and (iv) if the automatic Continuation of a LIBO Rate Loan would result in the
last day of the new Interest Period ending on a date after the Commitment
Termination Date, then such LIBO Rate Loan shall automatically be Converted into
a Base Rate Loan. The Borrower may from time to time irrevocably elect that all,
or any portion in an aggregate minimum amount of $10,000,000 and an integral
multiple of $1,000,000 in excess thereof, of any LIBO Rate Loan be Converted
into a Base Rate Loan by delivering a Continuation/Conversion Notice to the
Administrative Agent at or before 10:00 A.M., San Francisco time, on the
Business Day of the requested Conversion. Each delivery of a Continuation/
Conversion Notice shall constitute a certification and warranty by the Borrower
that on the date of delivery of such notice no Default has occurred and is
continuing. If prior to the time of such Continuation or Conversion any matter
certified to by the Borrower by reason of the immediately preceding sentence
will not be true and correct at such time if then made, the Borrower will
immediately so notify the Administrative Agent. Except to the extent, if any,
that prior to the time of such Continuation or Conversion the Administrative
Agent shall have received written notice to the contrary from the Borrower, such
certification and warranty shall be deemed to be made at the date of such
Continuation or Conversion as if then made. Upon the occurrence and during the
continuance of any Event of Default under Section 8.1.1, each LIBO Rate Loan
                                          -------------
shall convert automatically to a Base Rate Loan at the end of the Interest
Period then in effect for such LIBO Rate Loan.

          SECTION 2.5.  Funding.  Each Lender may, if it so elects, fulfill its
                        -------
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its non-U.S. branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such LIBO Rate Loan; provided,
                                                                 --------
however, that such LIBO Rate Loan shall nonetheless be deemed to have been made
-------
and to be held by such Lender, and the obligation of the Borrower to repay such
LIBO Rate Loan shall nevertheless be to such Lender for the account of such non-
U.S. branch, Affiliate or international banking facility. In addition, the
Borrower hereby consents and agrees that, for purposes of any determination to
be made for purposes of Sections 4.1, 4.2, 4.3, 4.4, 4.5, 4.6 or 4.7 it shall be
                        ------------  ---  ---  ---  ---  ---    ---
conclusively assumed that each Lender elected to fund all LIBO Rate Loans by
purchasing deposits in its LIBOR Office's interbank eurodollar markets.

Administrative Agent no earlier than 45 days but no later than 30 days prior to
the then existing Commitment Termination Date (the "Existing Commitment
                                                    -------------------
Termination Date") applicable to such Lenders. If a Lender agrees, in its
----------------
individual and sole discretion, to renew its Commitment, such Lender (a
"Renewing Lender") will notify the Administrative Agent, in writing, of its
 ---------------
decision to do so no earlier than 30 days prior to the Existing Commitment
Termination Date applicable to such Lender (but in any event no later than 20
days prior to the Existing Commitment Termination Date). Notwithstanding any
provision of this Agreement to the contrary, any notice by any Lender of its
willingness to renew its Commitment shall be revocable by such Lender in its
sole and absolute discretion at any time prior to the date which is 20 days
prior to the related Commitment Termination Date then in effect. The
Administrative Agent will notify the Borrower, in writing, of each Lender's
decision no later than 15 days prior to the Existing Commitment Termination Date
applicable to such Lender. The Renewing Lenders' Commitments will be renewed for
an additional 364 days from the Existing Commitment Termination Date applicable
to such Lenders, provided that (x) each extension of the Commitment
                 --------
Termination Date pursuant to this Section 2.6 shall be for a period of 364 days
                                  -----------
and (y) more than 50% of the Total Commitment Amount as of the Commitment
Termination Date then in effect is extended or otherwise committed to by
Renewing Lenders and any new Lenders.  Any Lender that declines the Borrower's
request for a Commitment renewal (a "Declining Lender") will have its Commitment
                                     ----------------
terminated on the Existing Commitment Termination Date applicable to such Lender
(without regard to any renewals by other Lenders), unless terminated earlier in
accordance with this Agreement.  The Borrower will have the right to accept
Commitments from Eligible Assignees acceptable to the Administrative Agent in an
amount up to the amount of the pre-termination Commitments of any Declining
Lenders, provided that the Renewing Lenders will have the right to increase
         --------
their Commitments up to the amount of the Declining Lenders' Commitments before
the Borrower will be permitted to substitute Eligible Assignees for the
Declining Lenders.

     minimum amount of $10,000,000.

            (b)    Each prepayment of Loans made pursuant to this Section 3.1.2
                                                                  -------------
shall be accompanied by accrued interest to the date of such prepayment on the
amount prepaid, but shall be without premium or penalty, except as may be
required by Section 4.5. The Borrower may, but shall not be required to,
            -----------
designate any voluntary prepayment of the Loans pursuant to Section 3.1.2(a) as
                                                            ----------------
a permanent prepayment in which case such permanent prepayment shall
automatically and permanently reduce the Total Commitment Amount by a like
amount. Amounts designated as permanent prepayments may not be reborrowed.

          SECTION 3.2.  Interest Provisions.  Interest on the outstanding
                        -------------------
principal amount of Loans shall accrue and be payable in accordance with this
Section 3.2.
-----------

            3.2.1.  Rates.
                    -----

            (a) Pursuant to an appropriately delivered Borrowing Request or
Continuation/Conversion Notice, the Borrower may elect that Loans comprising a
Borrowing accrue interest at a rate per annum:

            (i) on that portion maintained from time to time as a Base Rate
     Loan, equal to the sum of the Alternate Base Rate from time to time in
     effect plus the Applicable Margin from time to time in effect; and

                                      -17-
<PAGE>

            (ii) on that portion maintained as a LIBO Rate Loan, during each
     Interest Period applicable thereto, equal to the sum of the LIBO Rate for
     such Interest Period plus the Applicable Margin from time to time in
     effect.

Notwithstanding any other provision hereof, at such time as there shall exist
for any Lender a LIBOR Reserve Percentage which is greater than zero, the LIBO
Rate used in the determination of LIBO Rate Loans made by such Lender shall be
the LIBO Rate (Reserve Adjusted).

            (b) All LIBO Rate Loans shall bear interest from and including the
first day of the applicable Interest Period to (but not including) the last day
of such Interest Period at the interest rate determined as applicable to such
LIBO Rate Loan.

            3.2.2.  Post-Maturity Rates; Default Rates.  After the date any
                    ----------------------------------
principal amount of any Loan is due and payable (whether on the related
Commitment Termination Date, upon acceleration or otherwise), or after any
monetary Obligation of the Borrower shall become due and payable, the Borrower
shall pay, but only to the extent permitted by law, interest (after as well as
before judgment) on such overdue amount at a rate per annum equal to the
applicable interest rate of such overdue amount (or, if there is no applicable
interest rate, the Alternate Base Rate) plus the Applicable Margin plus 2% until
such amount is paid in full.

            3.2.3.  Payment Dates.  Interest and Utilization Fees accrued on
                    -------------
each Loan shall be payable, without duplication:

            (a) on the related Commitment Termination Date;

            (b) on the date of any payment or prepayment, in whole or in part,
     of principal outstanding on such Loan;

            (c) with respect to Base Rate Loans, on each Quarterly Payment Date
     occurring after the date of the initial Borrowing hereunder;

            (d) with respect to LIBO Rate Loans, the last day of each applicable
     Interest Period; and

            (e) on that portion of any Loans which is accelerated pursuant to
     Section 8.2 or Section 8.3, immediately upon such acceleration.
     -----------    -----------

          Interest accrued on Loans or other monetary Obligations arising under
or any Loan Document after the date such amount is due and payable (whether on
the related Commitment Termination Date, upon acceleration or otherwise) shall
be payable upon demand.

            3.2.4.  Interest Rate Determination.  The Administrative Agent shall
                    ---------------------------
determine the interest rate applicable to LIBO Rate Loans and shall give prompt
notice to the Borrower and the Lenders of such determination, and its
determination thereof shall be conclusive in the absence of manifest error. So
long as any Base Rate Loan is outstanding, the Administrative Agent shall
promptly give notice to the Borrower and the Lenders of the Alternate Base Rate
in effect at the time such Loan is made and of any changes therein.

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

          SECTION 4.1.  LIBO Rate Lending Unlawful.  If any Lender shall
                        --------------------------
reasonably determine (which determination shall, upon notice thereof to the
Borrower and the Administrative Agent, be conclusive and binding on the Borrower
absent manifest error) that the introduction of or any change in or in the
interpretation of any law, rule or regulation makes it unlawful, or any central
bank or other governmental authority or comparable agency asserts that it is
unlawful, for such Lender to make, continue or maintain any Loan as, or to
convert any Loan into, a LIBO Rate Loan, the obligations of such Lender to make,
continue, maintain or convert any such Loans shall, upon such determination,
forthwith be suspended until such Lender shall notify the Administrative Agent
that the circumstances causing such suspension no longer exist, and all LIBO
Rate Loans of such Lender shall automatically convert into Base Rate Loans at
the end of the then current Interest Periods with respect thereto or sooner if
required by such law or assertion.

          SECTION 4.2.  Inability to Determine Rates.  If the Administrative
                        ----------------------------
Agent shall have determined that, by reason of circumstances affecting the
Administrative Agent's relevant market, adequate means do not exist for
ascertaining the interest rate applicable hereunder to LIBO Rate Loans, then,
upon notice from the Administrative Agent to the Borrower and the Lenders, the
obligations of all Lenders under Section 2.3 and Section 2.4 to make or
                                 -----------     -----------
continue any Loans as, or to convert any Loans into, LIBO Rate Loans shall
forthwith be suspended until

                                      -19-
<PAGE>

the Administrative Agent shall notify the Borrower and the Lenders that the
circumstances causing such suspension no longer exist.

          SECTION 4.3.  Increased LIBO Rate Loan Costs.  If after the date
                        ------------------------------
hereof, the adoption of any applicable law, rule or regulation, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender (or its
LIBOR Office) with any request or directive (whether or not having the force of
law) of any such authority, central bank or comparable agency shall increase the
cost to such Lender of, or result in any reduction in the amount of any sum
receivable by such Lender in respect of, making, continuing or maintaining (or
of its obligation to make, continue or maintain) any Loans as, or of converting
(or of its obligation to convert) any Loans into, LIBO Rate Loans, then the
Borrower agrees to pay to the Administrative Agent for the account of each
Lender the amount of any such increase or reduction. Such Lender shall promptly
notify the Administrative Agent and the Borrower in writing of the occurrence of
any such event, such notice to state, in reasonable detail, the reasons therefor
and the additional amount required fully to compensate such Lender for such
increased cost or reduced amount. Such additional amounts shall be payable by
the Borrower directly to such Lender within ten Business Days of its receipt of
such notice, and such notice shall be binding on the Borrower absent clear and
convincing evidence to the contrary.

          SECTION 4.4.  Obligation to Mitigate.  Each Lender agrees that as
                        ----------------------
promptly as practicable after it becomes aware of the occurrence of an event
that would entitle it to give notice pursuant to Section 4.l, 4.3 or 4.6, and in
                                                 -----------  ---    ---
any event if so requested by the Borrower, each Lender shall use reasonable
efforts to make, fund or maintain its affected Loans through another lending
office if as a result thereof the increased costs would be avoided or materially
reduced or the illegality would thereby cease to exist and if, in the reasonable
opinion of such Lender, the making, funding or maintaining of such Loans through
such other lending office would not in any material respect be disadvantageous
to such Lender, contrary to such Lender's normal banking practices or violate
any applicable law or regulation. No change by a Lender in its Domestic Office
or LIBOR Office made for such Lender's convenience shall result in any increased
cost to the Borrower. The Borrower shall not be obligated to compensate any
Lender for the amount of any additional amount pursuant to Section 4.1, 4.3 or
                                                           -----------  ---
4.6 accruing prior to the date which is 90 days before the date on which such
---
Lender first notifies the Borrower that it intends to claim such compensation;
it being understood that the calculation of the actual amounts may not be
possible within such period and that such Lender may provide such calculation as
soon as reasonably practicable thereafter without affecting or limiting the
Borrower's payment obligation thereunder. If any Lender demands compensation
pursuant to Section 4.1, 4.3 or 4.6 with respect to any LIBO Rate Loan, the
            -----------  ---    ---
Borrower may, at any time upon at least one Business Days' prior notice to such
Lender through the Administrative Agent, elect to convert such Loan into a Base
Rate Loan. Thereafter, unless and until such Lender notifies the Borrower that
the circumstances giving rise to such notice no longer apply, all such LIBO Rate
Loans by such Lender shall bear interest as Base Rate Loans, notwithstanding any
prior election by the Borrower to the contrary. If such Lender notifies the
Borrower that the circumstances giving rise to such notice no longer apply, the
Borrower may elect that the principal amount of each such Loan again bear
interest as LIBO Rate Loans in accordance with

                                      -20-
<PAGE>

this Agreement, on the first day of the next succeeding Interest Period
applicable to the related LIBO Rate Loans of other Lenders. Additionally, the
Borrower may, at its option, upon at least five Business Days' prior notice to
such Lender, elect to prepay in full, without premium or penalty, such Lender's
affected LIBO Rate Loans. If the Borrower elects to prepay any Loans pursuant to
this Section 4.4, the Borrower shall pay within ten Business Days after written
     -----------
demand any additional increased costs of such Lender accruing for the period
prior to such date of prepayment. If such conversion or prepayment is made on a
day other than the last day of the current Interest Period for such affected
LIBO Rate Loans, such Lender shall be entitled to make a request for, and the
Borrower shall pay, compensation under Section 4.5.
                                       -----------

          SECTION 4.5.  Funding Losses.  In the event any Lender shall incur any
                        --------------
loss or expense (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender
to make, continue or maintain any portion of the principal amount of any Loan
as, or to convert any portion of the principal amount of any Loan into, a LIBO
Rate Loan) as a result of:

          (a) any conversion or prepayment of the principal amount of any LIBO
     Rate Loans on a date other than the scheduled last day of the Interest
     Period applicable thereto, whether pursuant to Section 3.1 or otherwise;
                                                    -----------

          (b) the Borrower's failure to borrow or prepay any LIBO Rate Loans in
     accordance with the Borrowing Request therefor or the notice of prepayment
     therefor delivered under Section 3.1.2(a)(iv); or
                              --------------------

          (c) any Loans not being continued as, or converted into, LIBO Rate
     Loans in accordance with the Continuation/Conversion Notice therefor;

then, upon the written notice of such Lender to the Borrower (with a copy to the
Administrative Agent), the Borrower shall, within ten Business Days of its
receipt thereof, pay directly to such Lender such amount as will (in the
reasonable determination of such Lender) reimburse such Lender for such loss or
expense. Such written notice (which shall include calculations in reasonable
detail) shall be binding on the Borrower absent manifest error.

          SECTION 4.6.  Increased Capital Costs.  If after the date hereof any
                        -----------------------
change in, or the introduction, adoption, effectiveness, interpretation,
reinterpretation or phase-in of, any applicable law or regulation, directive,
guideline, decision or request (whether or not having the force of law) of any
court, central bank, regulator or other governmental authority affects the
amount of capital required to be maintained by any Lender, and such Lender
reasonably determines that the rate of return on its capital as a consequence of
its Commitment or the Loans made by such Lender is reduced in a material amount
to a level below that which such Lender could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender to the Borrower, the Borrower shall pay within ten
Business Days after such demand directly to such Lender additional amounts
sufficient to compensate such Lender for such reduction in rate of return. A
statement of such Lender as to any such additional amount or amounts (including
calculations thereof in reasonable detail) shall be binding on the Borrower
absent manifest error.

          SECTION 4.7.  Taxes.
                        -----

          (a) All payments by the Borrower of principal of, and interest on, the
Loans and all other amounts payable hereunder shall be made free and clear of
and without deduction for any present or future income, excise, stamp or
franchise taxes and other taxes, fees, duties, withholdings or other charges of
any nature whatsoever imposed by any taxing authority, but excluding franchise
taxes or taxes imposed on or measured by any Lender's net income, in each case,
imposed as a result of a connection between the Lender and the jurisdiction
imposing the tax (other than a connection arising solely from the Lender having
executed, delivered or performed its obligations or received a payment under, or
enforced, this Agreement),  and the Lenders will use reasonable efforts to
minimize, to the extent possible, any such applicable taxes (such non-excluded
items being called "Taxes"). In the event that any withholding or deduction from
                    -----
any payment to be made by the Borrower hereunder is required in respect of any
Taxes pursuant to any applicable law, rule or regulation, then the Borrower
will:

               (i)   pay directly to the relevant authority the full amount
     required to be so withheld or deducted;

               (ii)  within 30 days after such payment forward to the
     Administrative Agent an official receipt or other documentation
     satisfactory to the Administrative Agent evidencing such payment to such
     authority; and

               (iii) pay to the Administrative Agent for the account of the
     Lenders such additional amount or amounts as is necessary to ensure that
     the net amount actually received by each Lender will equal the full amount
     such Lender would have received had no such withholding or deduction been
     required.

Moreover, if any Taxes are directly asserted against the Administrative Agent or
any Lender with respect to any payment received by the Administrative Agent or
such Lender hereunder, the Administrative Agent or such Lender may pay such
Taxes and, upon receipt of notice from the Administrative Agent or such Lender
within 30 days after such payment, the Borrower will promptly pay such
additional amounts (including any penalties, interest or expenses ) as are
necessary so that the net amount received by such person after the payment of
such Taxes (including any Taxes on such additional amount) shall equal the
amount such person would have received had no such Taxes been asserted.

          (b) If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Administrative Agent, for the account
of the respective Lenders, the required receipts or other required documentary
evidence, the Borrower shall indemnify the Lenders for any incremental Taxes,
interest or penalties that may become payable by any Lender as a result of any
such failure.  For purposes of this Section 4.7, a distribution hereunder by the
                                    -----------
Administrative Agent or any Lender to or for the account of any Lender shall be
deemed a payment for the account of the Borrower.

          (c) Each Lender that is not a United States person as defined in
Section 7701(a)(3) of the Code (a "Non-U.S. Lender") shall deliver to the
                                   ---------------
Borrower and the Administrative Agent two copies of either U.S. Internal Revenue
Service Form W-8BEN or

                                      -22-
<PAGE>

Form W-8ECI, or any subsequent versions thereof or successors thereto properly
completed and duly executed by such Non-U.S. Lender claiming complete exemption
from, or a reduced rate of, U.S. federal withholding tax on all payments by the
Borrower under the Loan Documents. Such forms shall be delivered by each Non-
U.S. Lender on or before the date it becomes a party to this Agreement. In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose). The Borrower shall not
be required to increase any such amounts payable to any Non-U.S. Lender with
respect to any Taxes (i) that are attributable to such Non-U.S. Lender's failure
to comply with the requirements of this Section 4.7(c) or (ii) that are United
                                        --------------
States withholding taxes imposed on amounts payable to such Lender at the time
the Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was entitled, at the time of assignment, to receive
additional amounts from the Borrower with respect to such Taxes pursuant to
Section 4.7(a). Notwithstanding any other provision of this Section 4.7(c), a
--------------                                              --------------
Non-U.S. Lender shall not be required to deliver any form pursuant to this
Section 4.7(c) that such Non-U.S. Lender is not legally able to deliver.
--------------

          SECTION 4.8.  Payments, Computations.
                        ----------------------

          (a) Unless otherwise expressly provided herein, all payments by the
Borrower pursuant to any Loan Document shall be made by the Borrower to the
Administrative Agent for the pro rata account of the Lenders entitled to receive
                             --- ----
such payment.  All such payments required to be made to the Administrative Agent
shall be made, without setoff, deduction or counterclaim, not later than 11:00
A.M., San Francisco time, on the date due, in Same Day Funds, to Bank of
America, N.A., 901 Main Street, Dallas, TX 75202, Attention: Credit Services-
Agency, ABA #111000012, Account No.: 1292000883, Reference: Edison Mission
Energy, or such account as the Administrative Agent shall specify from time to
time by notice to the Borrower; provided that such payment shall be deemed made
                                --------
timely if made by wire transfer and by such time as an Authorized Representative
has advised the Administrative Agent of the applicable Federal Reserve System
wire transfer confirmation number.  Funds received after that time shall be
deemed to have been received by the Administrative Agent on the next succeeding
Business Day.  The Administrative Agent shall promptly remit in Same Day Funds
to each Lender its share, if any, of such payments received by the
Administrative Agent for the account of such Lender.

          (b) Unless the Borrower or any Lender has notified the Administrative
Agent prior to the date any payment to be made by it is due, that it does not
intend to remit such payment, the Administrative Agent may, in its sole and
absolute discretion, assume that the Borrower or Lender, as the case may be, has
timely remitted such payment and may, in its sole and absolute discretion and in
reliance thereon, make available such payment to the Person entitled thereto.
If such payment was not in fact remitted to the Administrative Agent in Same Day
Funds, then:

          (i) if the Borrower failed to make such payment, each Lender shall
     forthwith on demand repay to the Administrative Agent the amount of such
     assumed payment made

                                      -23-
<PAGE>

     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 the Federal Funds Rate; and

          (ii) if any Lender failed to make such payment, the Administrative
     Agent shall be entitled to recover such corresponding amount on demand from
     such Lender.  If such Lender does not pay such corresponding amount
     forthwith upon the Administrative Agent's demand therefor, the
     Administrative Agent promptly shall notify the Borrower, and the Borrower
     shall pay such corresponding amount to the Administrative Agent to the
     extent such amount was received by the Borrower.  The Administrative Agent
     also shall be entitled to recover interest on such corresponding amount in
     respect of each day from the date such corresponding amount was made
     available by the Administrative Agent to the Borrower to the date such
     corresponding amount is recovered by the Administrative Agent, (A) if such
     corresponding amount is recovered from such Lender, at a rate per annum
     equal to the daily Federal Funds Rate or (B) if such corresponding amount
     is recovered from the Borrower, at a rate per annum equal to the interest
     rate applicable to such Borrowing; provided, however, that in no event
                                        --------  -------
     shall the Administrative Agent be entitled to a double recovery of such
     interest or such corresponding amount.  Nothing herein shall be deemed to
     relieve any Lender from its obligation to fulfill its Commitment or to
     prejudice any rights which the Administrative Agent or the Borrower may
     have against any Lender as a result of any default by such Lender
     hereunder.

          (c) All interest and fees shall be computed on the basis of the actual
number of days (including the first day but excluding the last day) occurring
during the period for which such interest or fee is payable over a year
comprised of 360 days (or, in the case of interest on a Base Rate Loan, 365 days
or, if appropriate, 366 days).  Whenever any payment to be made shall otherwise
be due on a day which is not a Business Day, such payment shall (except as
otherwise required by clause (c) of the definition of the term "Interest Period"
                      ----------                                ---------------
with respect to LIBO Rate Loans) be made on the next succeeding Business Day and
such extension of time shall be included in computing interest and fees, if any,
in connection with such payment.

          SECTION 4.9.  Sharing of Payments.  If any Lender shall obtain any
                        -------------------
payment or other recovery (whether voluntary, involuntary, by application of

          SECTION 9.1.  Appointment and Authorization of Administrative Agent.
                        -----------------------------------------------------
Each Lender hereby appoints Bank of America as its Administrative Agent under
and for purposes of each Loan Document.  Each Lender hereby irrevocably (subject
to Section 9.9) designates and authorizes Administrative Agent to take such
   -----------
action on its behalf under the provisions of this

                                      -40-
<PAGE>

Agreement and each other Loan Document and to exercise such powers and perform
such duties as are expressly delegated to it by the terms of this Agreement or
any other Loan Document, together with such powers as are reasonably incidental
thereto. Notwithstanding any provision to the contrary contained elsewhere in
this Agreement or in any other Loan Document, the Administrative Agent shall not
have any duties or responsibilities, except those expressly set forth herein,
nor shall the Administrative Agent have or be deemed to have any fiduciary
relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent. Without limiting the generality of the foregoing sentence,
the use of the term "agent" in this Agreement with reference to the
Administrative Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable law.
Instead, such term is used merely as a matter of market custom, and is intended
to create or reflect only an administrative relationship between independent
contracting parties.

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

          SECTION 9.3.  Liability of Administrative Agent.  No Administrative
                        ---------------------------------
Agent-Related Person shall (i) be liable for any action taken or omitted to be
taken by any of them under or in connection with this Agreement or any other
Loan Document or the transactions contemplated hereby (except for its own gross
negligence or willful misconduct in connection with its duties expressly set
forth herein), or (ii) be responsible in any manner to any Lender or participant
for any recital, statement, representation or warranty made by the Borrower or
any officer thereof, contained in this Agreement or in any other Loan Document,
or in any certificate, report, statement or other document referred to or
provided for in, or received by the Administrative Agent under or in connection
with, this Agreement or any other Loan Document, or the validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document, or for any failure of the Borrower or any other party to any Loan
Document to perform its obligations hereunder or thereunder.  No Administrative
Agent-Related Person shall be under any obligation to any Lender or participant
to ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of the Borrower or any
Subsidiary or Affiliate thereof.

          SECTION 9.4.  Reliance by Administrative Agent.
                        --------------------------------

          (a) The Administrative Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, communication, signature,
resolution, representation, notice, consent, certificate, affidavit, letter,
telegram, facsimile, telex or telephone message, statement or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons, and upon advice and statements of
legal counsel (including counsel to the Borrower), independent accountants and
other experts

                                      -41-
<PAGE>

selected by the Administrative Agent. The Administrative Agent shall be fully
justified in failing or refusing to take any action under any Loan Document
unless it shall first receive such advice or concurrence of the Required Lenders
as it deems appropriate and, if it so requests, it shall first be indemnified to
its satisfaction by Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases by fully protected in acting, or in
refraining from acting, under this Agreement or any other Loan Document in
accordance with a request or consent of the Required Lenders or all the Lenders,
if required hereunder, and such request and any action taken or failure to act
pursuant thereto shall be binding upon all of the Lenders and participants.
Where this Agreement expressly permits or prohibits an action unless the
Required Lenders otherwise determine, and in all other instances, the
Administrative Agent may, but shall not be required to, initiate any
solicitation for the consent or a vote of the Lenders.

          (b) For purposes of determining compliance with the conditions
specified in Section 5.1, each Lender and participant shall be deemed to have
             -----------
consented to, approved or accepted or to be satisfied with, each document or
other matter either sent by the Administrative Agent to each Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Lender.

          SECTION 9.5.  Notice of Default.  The Administrative Agent shall not
                        -----------------
be deemed to have knowledge or notice of the occurrence of any Default or Event
of Default, except with respect to defaults in the payment of principal,
interest and fees required to be paid to the  Administrative Agent for the
account of the Lenders, unless the Administrative Agent shall have received
written notice from a Lender or the Borrower referring to this Agreement,
describing such Default or Event of Default and stating that such notice is a
"notice of default".  The Administrative Agent will notify the Lenders of its
receipt of any such notice.  The Administrative Agent shall take such action
with respect to such Default or Event of Default as may be directed by the
Required Lenders in accordance with Article 8; provided, however, that unless
                                               --------  -------
and until the Administrative Agent has received any such direction, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interest of the Lenders.

          SECTION 9.6.  Credit Decision; Disclosure of Information by
                        ---------------------------------------------
Administrative Agent.  Each Lender and participant acknowledges that no
--------------------
Administrative Agent-Related Person has made any representation or warranty to
it, and that no act by the Administrative Agent hereinafter taken, including any
consent to and acceptance of any assignment or review of the affairs of the
Borrower or any of its Subsidiaries or Affiliates, shall be deemed to constitute
any representation or warranty by any Administrative Agent-Related Person to any
Lender or participant as to any matter, including whether the Administrative
Agent-Related Persons have disclosed material information in their possession.
Each Lender, including any Lender by assignment, and each participant represents
to the Administrative Agent that it has, independently and without reliance upon
any Administrative Agent-Related Person and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, prospects, operations, property, financial and
other condition and creditworthiness of the Borrower and its Subsidiaries and
Affiliates, and all applicable bank regulatory laws relating to the transactions
contemplated hereby, and made its own decision to

                                      -42-
<PAGE>

enter into this Agreement and to extend credit to the Borrower hereunder. Each
Lender and participant also represents that it will, independently and without
reliance upon any Administrative Agent-Related Person and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement and the other Loan Documents, and to make such
investigations as it deems necessary to inform itself as to the business,
prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and its Subsidiaries and Affiliates. Except for
notices, reports and other documents expressly required to be furnished to
Lenders by the Administrative Agent herein, the Administrative Agent shall not
have any duty or responsibility to provide any Lender or participant with any
credit or other information concerning the business, prospects, operations,
property, financial and other condition or creditworthiness of the Borrower or
any of its Subsidiaries or Affiliates which may come into the possession of any
Administration Agent-Related Person.

          SECTION 9.7.  Indemnification of Administrative Agent.  Whether or not
                        ---------------------------------------
the transactions contemplated hereby are consummated, the Lenders shall
indemnify upon demand each Administrative Agent-Related Person (to the extent
not reimbursed by or on behalf of the Borrower and without limiting the
obligation of the Borrower to do so), pro rata, and hold harmless each
Administrative Agent-Related Person from and against any and all Indemnified
Liabilities incurred by it; provided, however, that no Lender shall be liable
                            --------  -------
for the payment to any Administrative Agent-Related Person of any portion of
such Indemnified Liabilities resulting from such Person's gross negligence or
willful misconduct; provided, further however, that no action taken in
                    --------  ------- -------
accordance with the directions of the Required Lenders shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section.
Without limitation of the foregoing, each Lender shall reimburse the
Administrative Agent upon demand for its ratable share of any costs or out-of-
pocket expenses (including all reasonable fees and disbursements of any law firm
or other external counsel and the allocated cost of internal legal services and
all disbursements of internal counsel) incurred by the Administrative Agent in
connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any document
contemplated by or referred to herein, to the extent that the Administrative
Agent is not reimbursed for such expenses by or on behalf of the Borrower.  The
undertaking in this Section shall survive the payment of all Obligations
hereunder and the resignation or replacement of the Administrative Agent.

          SECTION 9.8.  Administrative Agent in Individual Capacity.  Bank of
                        -------------------------------------------
America and its Affiliates may make loans to, issue letters of credit for the
account of, accept deposits from, acquire equity interests in and generally
engage in any kind of banking, trust, financial advisory, underwriting or other
business with the Borrower and its Subsidiaries and Affiliates as though Bank of
America were not the Administrative Agent hereunder and without notice to or
consent of the Lenders.  The Lenders and participants acknowledge that, pursuant
to such activities, Bank of America or its Affiliates may receive information
regarding the Borrower or its Subsidiaries or its Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Borrower or such Subsidiary or such Affiliate) and acknowledge that the
Administrative Agent shall be under no obligation to provide such information to
them.  With

                                      -43-
<PAGE>

respect to its Loans, Bank of America shall have the same rights and powers
under this Agreement as any other Lender and may exercise the same as though it
were not the Administrative Agent.

          SECTION 9.9.  Resignation by Administrative Agent.  The Administrative
                        -----------------------------------
Agent may resign as the Administrative Agent upon 30 days' notice to the Lenders
and to the Borrower.  If the Administrative Agent resigns under this Agreement,
the Required Lenders shall appoint from among the Lenders a successor
administrative agent for the Lenders which successor administrative agent shall
be consented  to by the Borrower at all times other than during the existence of
an Event of Default (which approval of the Borrower shall not be unreasonably
withheld or delayed).  If no successor administrative agent is appointed prior
to the effective date of the resignation of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Lenders and
Borrower, a successor administrative agent from among the Lenders.  Upon the
acceptance of its appointment as successor administrative agent hereunder, such
successor administrative agent shall succeed to all the rights, powers and
duties of the retiring Administrative Agent and the term "Administrative Agent"
shall mean such successor administrative agent and the retiring Administrative
Agent's appointment, powers and duties as the Administrative Agent shall be
terminated.  After any retiring Administrative Agent's resignation hereunder as
the Administrative Agent, the provisions of this Article 9 and Sections 10.3 and
                                                               -------------
10.4 shall inure to its benefit as to any actions taken or omitted to be taken
----
by it while it was the Administrative Agent under this Agreement.  If no
successor administrative agent has accepted appointment as the Administrative
Agent by the date which is 30 days following a retiring Administrative Agent's
notice of resignation, the retiring Administrative Agent's resignation shall
nevertheless thereupon become effective and the Lenders shall perform all of the
duties of the Administrative Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above.

          SECTION 9.10. Arranger.  As Arranger, Banc of America Securities LLC
                        --------
shall have no right, power, obligation, liability, responsibility or duty under
the Loan Documents.  Without limiting the foregoing, Banc of America Securities
LLC shall have no fiduciary relationship with any Lender or any participant.
Each Lender acknowledges that it has not relied, and will not rely, on Banc of
America Securities LLC in deciding to enter into this Agreement or in taking or
not taking action hereunder or under any other Loan Document.

                                   ARTICLE 10

                            MISCELLANEOUS PROVISIONS

          SECTION 10.1.  Waivers, Amendments.
                         -------------------

          (a) The provisions of each Loan Document may from time to time be
amended, modified or waived, if such amendment, modification or waiver is in
writing and consented to by the Borrower and the Required Lenders; provided,
                                                                   --------
however, that no such amendment, modification or waiver shall (i) forgive or
-------
reduce the principal amount or extend the final scheduled date of maturity of
any Loan, reduce the stated rate of any interest or fee payable hereunder or
extend the scheduled date of any payment thereof, or increase the amount or
extend

                                      -44-
<PAGE>

the expiration date of any Lender's Commitment without the consent of each
Lender directly affected thereby; (ii) amend, modify or waive any provision of
this Section 10.1 or any percentage specified in the definition of Required
     ------------
Lenders, or consent to the assignment or transfer by the Borrower of any of its
rights and obligations under the Loan Documents, in each case without the
written consent of all Lenders; or (iii) amend, modify or waive any pro rata
provision of Section 4.9, or any provision in the Loan Documents which provides
             -----------
for amounts paid in respect of the Obligations to be shared among the Lenders
ratably, without the consent of all Lenders.  Any such waiver and any such
amendment, supplement or modification shall apply equally to each of the Lenders
and shall be binding upon the Borrower, the Lenders, the Administrative Agent
and all future holders of the Loans.  In the case of any waiver, the Borrower,
the Lenders and the Administrative Agent shall be restored to their former
position and rights under the Loan Documents, and any Default or Event of
Default waived shall be deemed to be cured and not continuing; but no such
waiver shall extend to any subsequent or other Default or Event of Default, or
impair any right consequent thereon.

          (b) No failure or delay on the part of the Administrative Agent or any
Lender in exercising any power or right under any Loan Document shall operate as
a waiver thereof, nor shall any single or partial exercise of any such power or
right preclude any other or further exercise thereof or the exercise of any
other power or right.  No notice to or demand on the Borrower in any case shall
entitle it to any notice or demand in similar or other circumstances.  No waiver
or approval by the Administrative Agent or any Lender under any Loan Document
shall, except as may be otherwise stated in such waiver or approval, be
applicable to subsequent transactions.  No waiver or approval hereunder shall
require any similar or dissimilar waiver or approval thereafter to be granted
hereunder.

          SECTION 10.2.  Notices.
                         -------

          (a) All notices and other communications provided to any party hereto
under any Loan Document shall be in writing or by facsimile and addressed,
delivered or transmitted to such party at its address or facsimile number set
forth below its name on the signature pages hereof or set forth in the relevant
Lender Assignment Agreement or at such other address or facsimile number as may
be designated by such party in a written notice to the other parties.  Any
notice, if mailed and properly addressed with postage prepaid shall be effective
five Business Days after being sent or if properly addressed and sent by pre-
paid courier service, shall be deemed given when received; any notice, if
transmitted by facsimile, shall be deemed given when transmitted (if confirmed).

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

          (c) Electronic mail and internet and intranet websites may be used to
distribute routine communications, such as financial statements and other
information, and to

                                      -45-

Agent, the Lenders and the Borrower. No other legally-binding and/or time-
sensitive communication or Request for Borrowing or Continuation/Conversion
Notice may be sent by electronic mail without the consent of, or confirmation
to, the intended recipient in each instance.

          (d) The Administrative Agent and the Lenders shall be entitled to rely
and act upon any notices purportedly given by or on behalf of the Borrower even
if (i) such notices were not made in a manner specified herein, were incomplete
or were not preceded or followed by any other notice specified herein, or (ii)
the terms thereof, as understood by the recipient, varied from any confirmation
thereof.  The Borrower shall indemnify the Administrative Agent-Related Persons
and the Lenders from any loss, cost, expense or liability as a result of relying
on any notices purportedly given by or on behalf of the Borrower; provided,
                                                                  --------
however, that the Borrower shall not be required to indemnify any Administrative
-------
Agent-Related Person or any Lender from any loss, cost, expense or liability
caused by its own gross negligence or willful misconduct.

          SECTION 10.3.  Payment of Costs and Expenses.

     Borrower shall have no obligation to pay for the cost of the documentation
     of assignments or participations as provided in Section 10.11 (unless such
                                                     -------------
     assignment is made pursuant to Section 4.11);
                                    ------------

in each case, upon presentation of statement of account, whether or not the
transactions contemplated hereby are consummated.

          (b)   Without duplication of the Borrower's obligations under Section
                                                                        -------

---
Administrative Agent and the Lenders harmless from all liability for, any stamp
or other taxes which may be payable in connection with the execution, delivery
or enforcement of any Loan Document or with the Borrowings hereunder.  The
Borrower also agrees to reimburse the Administrative Agent and each Lender, as
applicable, promptly upon demand upon presentation of a statement of account in
reasonable detail for (x) all reasonable out-of-pocket costs and expenses
(including all reasonable fees and disbursements of any law firm or other
external counsel and the allocated cost of internal legal services and all

obligated to reimburse such costs and expenses that are found in a final
judgment by a court of competent jurisdiction to have been incurred in an
attempt to enforce such rights and remedies that were pursued by such
Administrative Agent or Lender in bad faith and without any reasonable basis in
fact or law.

          SECTION 10.4.  Indemnification.  Whether or not the transactions
                         ---------------

or indirectly to a claim, demand, action or cause of action that such Person
asserts or may assert against the Borrower, any of its Subsidiaries, any of its
Affiliates or any of their respective officers or directors; (b) any and all
claims, demands, actions or causes of action arising out of or relating to, the
Loan Documents, any predecessor loan documents, the Commitments, the use or
contemplated use of the proceeds of any Loan, or the relationship of the
Borrower, the Administrative Agent and the Lenders under this Agreement; (c) any

result of the preparation of any defense in connection with any foregoing claim,
demand, action, cause of action or proceeding, in all cases whether or not
arising out of the negligence of an Indemnitee, whether or not an Indemnitee is
a party to such claim, demand, action, cause of action or proceeding (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that no
                              -----------------------    --------
Indemnitee shall be entitled to indemnification for any loss caused by its own
gross negligence or willful misconduct or for any loss asserted against it by
another Indemnitee.  The agreements in this Section shall survive repayment of
all Obligations.

          SECTION 10.5.  Survival.  The obligations of the Borrower under

under Section 9.7, shall in each case survive any termination of this Agreement,

Commitments. The representations and warranties made by the Borrower in each
Loan Document shall survive the execution and delivery of such Loan Document.

          SECTION 10.6.  Severability.  Any provision of any Loan Document which
                         ------------
is prohibited or unenforceable in any jurisdiction shall, as to such provision
and such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the

                                      -47-
<PAGE>

remaining provisions of such Loan Document or affecting the validity or
enforceability of such provision in any other jurisdiction.

Notes and the rights and obligations of the parties under this Agreement shall
be governed by, and construed and interpreted in accordance with, the law of the
State of California. The Loan Documents, together with the fee letter referred
to in Section 3.3.3, the Commitment Letter (to the extent not inconsistent with
      -------------
this Agreement) and the letter agreement of even date herewith between Bank of
America and the Borrower, represent the agreement of the Borrower, the
Administrative Agent and the Lenders and supersede any and all prior agreements
and understandings, oral or written, relative or with respect to the subject
matter hereof, and there are no promises, undertakings, representations or
warranties by the Administrative Agent or any Lender relative to subject matter
hereof not expressly set forth or referred to in the Loan Documents.

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

respective successors and assigns; provided, however, that:
                                   --------  -------

          (a) the Borrower may not assign or transfer its rights or obligations

and Commitments to one or more other Persons in accordance with this Section
                                                                     -------
10.11.
-----

            10.11.1.  Assignments.
                      -----------

            (a) Any Lender (an "Assignor") may, in accordance with applicable
                                --------
law, at any time and from time to time assign to any Person that is an Eligible
Assignee (an "Assignee"), with the consent of the Administrative Agent and,
              --------
except at any time a Default or Event of Default shall have occurred and be
continuing, the Borrower (which, in each case, shall not be unreasonably
withheld or delayed (except that no such consent shall be necessary in the case
of an assignment to another Lender or to an Affiliate of a Lender)), all or any
part of its rights and obligations under this Agreement pursuant to a Lender
Assignment Agreement, executed by such Assignee, such Assignor and any other
Person whose consent is required pursuant to this

                                      -48-
<PAGE>

paragraph, and delivered to the Administrative Agent for its acceptance and
recording in the Register; provided that no such assignment to an Assignee
                           --------
(other than any Lender or any Affiliate thereof) shall be in an aggregate
principal amount of less than $10,000,000 (other than in the case of an
assignment of all of a Lender's interests under this Agreement), unless
otherwise agreed by the Borrower and the Administrative Agent; and provided,
                                                                   --------
further, that after giving effect to any such assignment the Assignor shall
-------
have a Commitment remaining of at least $10,000,000 in the aggregate amount
(other than in the case of an assignment of all of a Lender's interests under
this Agreement). Upon such execution, delivery, acceptance and recording, from
and after the effective date determined pursuant to such Lender Assignment
Agreement, (x) the Assignee thereunder shall be a party hereto and, to the
extent provided in such Lender Assignment Agreement, have the rights and
obligations of a Lender hereunder with a Commitment and/or Loans as set forth
therein, and (y) the Assignor thereunder shall, to the extent provided in such
Lender Assignment Agreement, be released from its obligations under this
Agreement (and, in the case of a Lender Assignment Agreement covering all of an
Assignor's rights and obligations under this Agreement, such Assignor shall
cease to be a party hereto).

          (b) The Administrative Agent shall, on behalf of the Borrower,
maintain at its address set forth below its name on its signature page hereof a
copy of each Lender Assignment Agreement delivered to it and a register (the
"Register") for the recordation of the names and addresses of the Lenders and
 --------
the Commitment of, and the principal amount of the Loans owing to, each Lender
from time to time.  The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrower, the Administrative Agent and the
Lenders shall treat each Person whose name is recorded in the Register as the
owner of the Loans and any Notes evidencing the Loans recorded therein for all
purposes of this Agreement.  Any assignment of any Loan, whether or not
evidenced by a Note, shall be effective only upon appropriate entries with
respect thereto being made in the Register (and each Note shall expressly so
provide).  Any assignment or transfer of all or part of a Loan evidenced by a
Note shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Note evidencing such Loan, accompanied by a duly
executed Lender Assignment Agreement, and thereupon one or more new Notes shall
be issued to the designated Assignee.

          (c) Upon its receipt of a Lender Assignment Agreement executed by an
Assignor, an Assignee and any other Person whose consent is required by Section
                                                                        -------
10.11.1(a), together with payment to the Administrative Agent of a registration
----------
and processing fee of $3,500, the Administrative Agent shall (i) promptly accept
such Lender Assignment Agreement and (ii) record the information contained
therein in the Register on the effective date determined pursuant thereto.

          (d) For the avoidance of doubt, the parties to this Agreement
acknowledge that the provisions of this Section 10.11.1 concerning assignments
                                        ---------------
of Loans relate only to absolute assignments and that such provisions do not
prohibit assignments creating security interests, including any pledge or
assignment by a Lender of any Loan or Note to any Federal Reserve Bank in
accordance with applicable law.

                                      -49-

            (e) The Borrower, upon receipt of written notice from the relevant
Lender, agrees to issue Notes to any Lender requiring Notes to facilitate
transactions of the type described in paragraph (d) of this Section 10.11.1.
                                      -------------         ---------------

            10.11.2.  Participations.  Each Lender may from time to time,
                      --------------
without the consent of any other Person, grant participations to one or more
other Persons (including another Lender) all or any portion of its pro rata
share of its Commitment and/or Extensions of Credit; 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 purpose of Article 4 (but
only to the extent that the cost of such benefits to the Borrower does not
exceed the cost which the Borrower would have incurred in respect of such Lender
absent the participation) and subject to Sections 4.9 and 4.10, (iv) the
                                         ---------------------
Borrower, the Administrative Agent and the other Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, (v) the participation agreement shall not
restrict an increase in the combined Commitments or in the granting Lender's
Commitment or pro rata share, so long as the amount of the participation of
interest is not increased, and (vi) the consent of the holder of such
participation interest shall not be required for amendments or waivers of
provisions of the Loan Documents; provided, however, that the assigning Lender
                                  --------  -------
may, in any agreement with a participant, give such participant the right to
consent to any matter which (A) extends the Commitment Termination Date as to
such participant or any other date upon which any payment of money is due to
such participant, (B) reduces the rate of interest owing to such participant,
any fee or any other monetary amount owing to such participant, or (C) reduces
the amount of any installment of principal owing to such participant. Any Lender
that sells a participation to any Person that is a "foreign corporation,
partnership or trust" within the meaning of the Code shall include in its
participation agreement with such Person a covenant by such Person that such
Person will comply with the provisions of Section 4.7(c) as if such Person were
                                          --------------
a Lender and provide that the Administrative Agent and the Borrower shall be
third party beneficiaries of such covenant.

          SECTION 10.12.  Other Transactions.  Nothing contained herein shall
                          ------------------
preclude the Administrative Agent or any other Lender from engaging in any
transaction, in addition to those contemplated by any Loan Document, with the
Borrower or any of its Affiliates in which the Borrower or such Affiliate is not
restricted hereby from engaging with any other Person.

          SECTION 10.13.  Submission To Jurisdiction; Waivers.  Each of the
                          -----------------------------------
Borrower, the Administrative Agent and the Lenders hereby irrevocably and
unconditionally:

          (a) submits for itself and its property in any legal action or
     proceeding relating to the Loan Documents to which it is a party, or for
     recognition and enforcement of any judgment in respect thereof, to the non-
     exclusive general jurisdiction of the courts of the State of California,
     the courts of the United States for the Central District of California, and
     appellate courts from any thereof;

          (b) consents that any such action or proceeding may be brought in such
     courts and waives any objection that it may now or hereafter have to the
     venue of any such

                                      -50-
<PAGE>

     action or proceeding in any such court or that such action or proceeding
     was brought in an inconvenient court and agrees not to plead or claim the
     same;

          (c) agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to such
     Person at its address set forth on its signature page hereof or at such
     other address of which the Administrative Agent shall have been notified
     pursuant to Section 10.2;
                 ------------

          (d) agrees that nothing herein shall affect the right to effect
     service of process in any other manner permitted by law or shall limit the
     right to sue in any other jurisdiction; and

          (e) waives, to the maximum extent not prohibited by law, any right it
     may have to claim or recover in any legal action or proceeding referred to
     in this Section any special, exemplary, punitive or consequential damages.

          SECTION 10.14.  WAIVERS OF JURY TRIAL.  THE BORROWER, THE
                          ---------------------

     connection herewith or therewith is solely that of debtor and creditor; and

          (c) no joint venture is created by any of the Loan Documents or
     otherwise exists by virtue of the transactions contemplated hereby among
     the Lenders or among the Borrower, the Administrative Agent and the

          SECTION 10.17.  Confidentiality.  Each of the Administrative Agent and
                          ---------------

                                               --------
shall prevent the Administrative Agent or any Lender from disclosing any such
