of $1,000,000.  This is a revolving credit, and Borrower may, during the
Availability Period, reborrow amounts repaid or prepaid.  No Loan nor any part
of any Loan shall be repaid except at the times and in the manner expressly
provided herein.

     2.3  Requests for Base Rate and Eurodollar Loans.  Each Base Rate Loan and
          -------------------------------------------
Eurodollar Loan shall be made upon irrevocable written or telephonic notice,
confirmed promptly in writing, substantially in the form of Exhibit A-1 hereto,
by Borrower to Administrative Agent received by Administrative Agent not later
than 9:00 a.m. California time not less than three (3) Eurodollar Banking Days
prior to the Borrowing Date (which must be a Eurodollar Banking Day) of a
Eurodollar Loan and not later than 9:00 a.m. California time on the proposed
Borrowing Date (which must be a Business Day) of a Base Rate Loan.  Upon receipt
of a request for a Base Rate Loan and Eurodollar Loan, Administrative Agent
shall promptly notify the Banks of the amount, the Interest Period(s), if
applicable, and the Borrowing Date requested by Borrower.  After giving effect
to any borrowing of Eurodollar Loans or any conversion or continuation of
Eurodollar Loans, there shall not be more than 10 different Interest Periods for
Eurodollar Loans and Bid Rate Loans in the aggregate at any time.

     2.4  Requests for Bid Rate Loans.  (a)  Each Bid Rate Loan shall be made
          ---------------------------
upon irrevocable written or telephonic notice, confirmed promptly in writing,
substantially in the form of Exhibit A-2 hereto, by Borrower and must be
received by Administrative Agent not later than 9:00 a.m. California time one
Business Day prior to the Borrowing Date for such Loan, specifying the Borrowing
Date (which must be a Business Day), the amount, and the Interest Period.  In
requesting a Bid Rate Loan, Borrower may specify up to a maximum of three
alternative Interest Periods for the Bid Rate Loan.  After giving effect to any
borrowing of Bid Rate Loans, there shall not be more than 10 different Interest
Periods for Bid Rate Loans and Eurodollar Loans in the aggregate at any one
time.

                                     -12-
<PAGE>

     (b)  Upon receipt of a request for a Bid Rate Loan pursuant to paragraph
(a) above, Administrative Agent shall promptly notify the Banks of the amount,
the Interest Period(s) and the Borrowing Date requested by Borrower. If Bank of
America elects to advance a Bid Rate Loan it shall notify Borrower and
Administrative Agent of the amount, the Interest Period(s) and the Bid Rate
(with any fraction of a percentage expressed as a decimal to the nearest
1/10,000 of one percent) upon which Bank of America desires to advance such a
Bid Rate Loan by 7:00 a.m. California time on such Borrowing Date. By 7:15 a.m.
California time on the Borrowing Date, each other Bank shall notify
Administrative Agent whether or not it will submit an offer in response to
Borrower's request for a Bid Rate Loan and each Bank submitting an offer shall
notify Administrative Agent of the amount, the Interest Period(s) and the Bid
Rate (with any fraction of a percentage expressed as a decimal to the nearest
1/10,000 of one percent) upon which such Bank desires to advance a Bid Rate
Loan. By 7:30 a.m. California time on the Borrowing Date Administrative Agent
shall give notice to Borrower, of the amount, the Interest Period and the Bid
Rate upon which each Bank desires to advance a Bid Rate Loan. Borrower shall,
before 7:45 a.m. California time on such Borrowing Date, elect which of the
offered Bid Rate Loans it desires to accept and notify Administrative Agent of
each offer that is being accepted by Borrower. Such acceptance by Borrower shall
be irrevocable. If Borrower accepts any of the offers for Bid Rate Loans,
Borrower must accept offers strictly based upon pricing and no other criteria.
If two or more Banks submit offers at identical pricing and Borrower accepts any
of such offers but does not wish to borrow the total amount offered by such
Banks, Borrower shall accept offers from all of such Banks on amounts allocated
among them pro rata (in multiples of $1,000,000) according to the amounts
offered by such Banks.

     (c)  If Borrower accepts one or more of the offers made by any Bank or
Banks pursuant to subsection (b) above, Administrative Agent shall, by 8:15 a.m.
California time on such Borrowing Date, notify each Bank as to the identity of
each Bank which is to make a Bid Rate Loan, the amount of the Loan to be made by
each Bank, the Interest Period, and the Bid Rate applicable to each such Loan.
Administrative Agent shall also notify each Bank by 8:15 a.m. California time on
such Borrowing Date if Administrative Agent has either received no offers in
response to Borrower's Loan Request for a Bid Rate Loan or if Borrower has
elected not to accept any of the offers received.

     (d)  Each Bank whose offer for a Bid Rate Loan has been accepted pursuant
to Section 2.4(b) shall determine for itself whether the conditions precedent in
Section 5.2 have been or will be satisfied on the Borrowing Date. On or before
11:00 a.m. California time on the Borrowing Date, each such Bank's Lending
Office will make available to Administrative Agent the principal amount of the
Bid Rate Loan in immediately available funds and Administrative Agent shall
promptly credit Borrower's account at Administrative Agent in immediately
available funds.

     2.5  Interest and Principal on Base Rate Loans.  Subject to Section 2.11(f)
          -----------------------------------------
herein, the outstanding Principal Amount of each Base Rate Loan shall bear
interest until payment is due in full (computed daily on the basis of a 365 or
366, as the case may be, day year and actual days elapsed) at the rate per annum
equal to the Base Rate.  Borrower shall pay interest on each Base Rate Loan on
each Interest Payment Date for the interest accruing since the previous Interest
Payment Date on such Base Rate Loan.  Borrower shall repay in full the Principal
Amount of each Base Rate Loan on the Termination Date or as provided in Section
2.10(c).

                                     -13-
<PAGE>

     2.6  Interest and Principal on Eurodollar Loans.  (a)  Subject to Section
          ------------------------------------------
2.11(f) herein, the outstanding Principal Amount of each Eurodollar Loan shall
bear interest until payment is due in full (computed daily on the basis of a
three hundred sixty (360) day year and actual days elapsed) at a rate per annum
equal to the Eurodollar Rate plus the Applicable Amount; plus, at all times
                             ----                        ----
until such time as the principal amount of the Loans and the principal amount of
the "Loans," as defined in the Multi-Year Credit Agreement, have been reduced to
zero, and thereafter with respect to each day on which the aggregate amount of
outstanding Loans plus the aggregate amount of outstanding "Loans", as defined
in the Multi-Year Credit Agreement, exceeds 33% of the Aggregate Long-Term and
Short-Term Commitments, the Utilization Fee (computed daily on the basis of a
three hundred sixty (360) day year and actual days elapsed).  Borrower shall pay
interest and the Utilization Fee on each Eurodollar Loan on each Interest
Payment Date for such Eurodollar Loan.  Borrower shall repay in full the
Principal Amount of each Eurodollar Loan on the last day of the Interest Period
for such Eurodollar Loan or as provided in Section 2.10(c).

     (b)  If any Reference Bank's Commitment shall terminate (otherwise than on
termination of all the Commitments), or for any reason whatsoever the Reference
Bank shall cease to be a Bank hereunder, that Reference Bank shall thereupon
cease to be a Reference Bank, and the Eurodollar Rate shall be determined on the
basis of the rates as notified by the remaining Reference Banks.  Each Reference
Bank shall use its best efforts to furnish quotations of rates to the
Administrative Agent as contemplated hereby.  If any of the Reference Banks
shall be unable or otherwise fails to supply such rates to the Administrative
Agent upon its request, the rate of interest shall be determined on the basis of
the quotations of the remaining Reference Banks or Reference Bank.

     2.7  Interest and Principal on Bid Rate Loans.  Subject to Section 2.11(f)
          ----------------------------------------
herein, the outstanding principal amount of each Bid Rate Loan shall bear
interest until payment is due in full (computed daily on the basis of a 360-day
year and actual days elapsed) at a rate per annum equal to the Bid Rate.
Borrower shall pay interest on each Bid Rate Loan on each Interest Payment Date
for such Bid Rate Loan.  Borrower shall repay in full the Principal Amount of
each Bid Rate Loan on the last day of the Interest Period of such Bid Rate Loan.

     2.8  Loan Accounts.  Each Bank shall open and maintain on its books one or
          -------------
more loan accounts in Borrower's name.  Each loan account shall show (without
duplication) as debits thereto each Bank's portion of each Base Rate Loan and/or
Eurodollar Loan and as credits thereto all Base Rate Loan and/or Eurodollar Loan
payments received by such Bank for the account of such Bank and applied to
principal so that the balance of the loan account(s) at all times reflect the
principal amount due each Bank from Borrower as Base Rate Loans and Eurodollar
Loans.  All entries in said books shall be presumptive evidence of the making of
each Base Rate Loan and Eurodollar Loan, the obligation of Borrower to repay
each Base Rate Loan and Eurodollar Loan, and all payments received and disbursed
by such Bank.  Borrower agrees that if, in the opinion of any Bank, a promissory
note or other evidence of debt is required or appropriate to reflect or enforce
any Loans outstanding to or to be made by such Bank, then Borrower shall
promptly execute and deliver to such Bank one or more promissory notes payable
to such Bank to evidence the Loans outstanding to such Bank under this Agreement
from time to time, together with such documents as such Bank may reasonably
request to evidence the due authorization, execution, delivery and
enforceability of such notes.  If any notes are issued

                                     -14-
<PAGE>

hereunder, Administrative Agent and Borrower may treat the payee of that note as
the owner of such note for all purposes.

     2.9  Master Bid Rate Notes.  Borrower shall execute a Master Bid Rate Note
          ---------------------
in the form of Exhibit B hereto in favor of each Bank.  The Master Bid Rate Note
of each Bank shall evidence the outstanding principal amount of Bid Rate Loans
made by such Bank, and shall be dated the first day of the Availability Period.
Each Bank is authorized to indicate upon the grid attached to its Master Bid
Rate Note the principal amount, interest rate and Interest Period of each Bid
Rate Loan and all payments of principal and interest thereon.  Such notations
shall be presumptively correct as to the aggregate unpaid principal amount of
the Bid Rate Loan made by such Bank, and interest due thereon, but the failure
by such Bank to make such notations shall not affect the obligations of Borrower
hereunder or under the Master Bid Rate Notes.

     2.10 Conversion of Loans Between Eurodollar Loans and Base Rate Loans and
          --------------------------------------------------------------------
Conversion of Interest Periods of Eurodollar Loans.  (a)  On any Eurodollar
--------------------------------------------------
Banking Day Borrower may convert on a pro rata basis among the Banks any
outstanding Base Rate Loans or Eurodollar Loans (but not Bid Rate Loans) into
any other type of Loan available to Borrower hereunder (but not to a Bid Rate
Loan), or Borrower may change the Interest Period of any Eurodollar Loan to
another Interest Period available under this Agreement, subject to the following
limitations:

          (i)  No conversion of any Eurodollar Loan into any other Loan and no
     conversion of the Interest Period of any Eurodollar Loan may be made except
     on the last day of an Interest Period with respect thereto; and

          (ii) Any conversion shall be preceded by an irrevocable written or
     telephonic notice from Borrower that it elects such conversion, which
     notice shall be received by Administrative Agent at least three (3)
     Eurodollar Banking Days prior to the date requested for such conversion
     from or into a Eurodollar Loan or conversion of the Interest Period of a
     Eurodollar Loan.

     (b)  Banks shall not be obligated to make or continue any Eurodollar Loan
when any Event of Default has occurred and is continuing, but any outstanding
Eurodollar Loan shall be automatically converted to a Base Rate Loan on the last
day of the Interest Period for which a Eurodollar Rate was determined by
Administrative Agent following occurrence of such Event of Default, and, unless
Section 2.11(f) is applicable, Borrower shall be obligated to pay interest at
the Base Rate from the date any Loan is so converted until such Loan is repaid
in full regardless of the date when Administrative Agent obtains knowledge of
such Event of Default.

     (c)  Each conversion of a Loan into a Base Rate Loan or a Eurodollar Loan,
as the case may be, shall be effected by each Bank, on behalf of Borrower, as
applicable, by making a simultaneous payment of the relevant Eurodollar Loan, or
Base Rate Loan, as the case may be, from the proceeds of the new Loans,
procedures with respect thereto to be governed by the provisions of Section 2.3,
except that disbursement shall be made by means of such payment rather than
directly to Borrower to the extent applicable with respect to each Bank.

                                     -15-
<PAGE>

     (d)  If upon the expiration of any Interest Period applicable to Eurodollar
Loans, Borrower has failed to select a new Interest Period to be applicable
thereto, or if any Event of Default or Unmatured Event of Default shall then
exist, Borrower shall be deemed to have elected to convert such Eurodollar Loans
into Base Rate Loans effective as of the expiration date of such current
Interest Period.

     2.11 Disbursements and Payments.  (a)  Each Base Rate Loan and Eurodollar
          --------------------------
Loan shall be made on a pro rata basis by Banks, and each Bank's portion of each
Loan shall be determined by application of its Normal Percentage.  Each Bid Rate
Loan shall be made entirely by the Bank whose offer was accepted by Borrower
pursuant to Section 2.4.  Each Bank's interest in each Loan and each payment to
such Bank under this Agreement shall be for the account of such Bank's Lending
Office.

     (b)  Each Loan and each payment of principal, interest and other sums under
this Agreement shall be made in immediately available funds (or such other funds
as Administrative Agent may require) at Bank of America's Agency Administrative
Services-West, 1850 Gateway Blvd., Concord, California 94520, ABA #111000012,
Acct No. 3750836479, Ref: Hughes Electronics Corporation or such other office
designated by Administrative Agent from time to time.

     (c)  Each Bank agrees it will make the funds which it is to advance
hereunder available to Bank of America's Agency Administrative Services-West,
1850 Gateway Blvd., Concord, California 94520, ABA #111000012, Acct No.
3750836479, Ref: Hughes Electronics Corporation or such other office designated
by Administrative Agent from time to time not later than 11:00 a.m. California
time on the Borrowing Date, and Administrative Agent will thereupon promptly
advance to Borrower the amount so received from Banks.

     (d)  Payment of all sums under this Agreement shall be made by Borrower to
Administrative Agent, and the latter shall promptly distribute to each Bank its
share of such payments.  Each payment by Borrower shall be made without setoff
or counterclaim and not later than 11:00 a.m. California time on the day such
payment is due.  All sums received after such time shall be deemed received on
the next Business Day.

     (e)  If Administrative Agent makes available to Borrower an amount due from
any Bank which such Bank fails to make available to Administrative Agent, or if
Administrative Agent makes available to any Bank an amount due from Borrower
which Borrower fails to make available to Administrative Agent, Borrower or such
Bank, as the case may be, shall, on demand, refund such amount to Administrative
Agent, together with interest thereon for the period during which such amount
was available to Borrower or such Bank, as the case may be, at the Federal Funds
Rate.

     (f)  Any sum of principal or interest payable by Borrower hereunder if not
paid when due shall bear interest (payable on demand) from its due date until
payment in full (computed daily on the basis of a 365 or 366, as the case may
be, day year and actual days elapsed) at a rate per annum equal to the Default
Rate.

                                     -16-
<PAGE>

     2.12 Facility Fee.  Borrower shall pay Administrative Agent for the account
          ------------
of the Banks, a facility fee at the rate per annum equal to the Applicable
Amount therefor on the Total Commitment (without regard to the amount of Loans
outstanding at any time hereunder and without giving effect to any reduction
pursuant to Section 2.1(c)) during the Availability Period; provided, however,
following any reduction in the Total Commitment pursuant to Section 3.5 or 3.6
(but not a reduction pursuant to Section 2.1(c)) the computation of the facility
fee shall be based upon such reduced Total Commitment as of the effective date
of such reduction.  The facility fee shall be computed on a calendar quarter
basis.  The facility fee shall be calculated on the basis of a 360-day year and
actual days elapsed, which results in a higher fee than if a 365/366-day year
were used, and shall be payable on the 10th day of each January, April, July and
October (for the facility fee accrued during the previous calendar quarter) and
on the Termination Date.

     2.13 Extension of Termination Date. (a) The Borrower may, no earlier than
          -----------------------------
60 days and not later than 45 days prior to the then effective Termination Date
(as it may be extended from time to time pursuant hereto), request in writing
that the Termination Date be extended for an additional 364 days by sending to
the Administrative Agent, which will promptly then provide a copy to each Bank,
an Extension Request.  After Borrower's request, each Bank may, in its sole
discretion, consent or not consent to such extension by giving written notice
thereof to the Administrative Agent no later than 21 days after its receipt of
such Extension Request.  Each Bank's annual decision as to whether to extend the
Termination Date shall be based, in part, on a new credit analysis utilizing
then current information in respect of Borrower's business, financial condition
and operations and other information furnished by Borrower.  Failure of any Bank
to respond within such 21 day period shall be deemed to be a refusal of such
request by such Bank.  The Administrative Agent shall promptly notify each Bank
and Borrower of any Bank's decision to reject the proposed extension.

     (b)  If, in accordance with the provisions of this Section 2.13, a Bank
consents to the extension of the Termination Date, the Termination Date for such
Bank shall be extended for 364 days from the then current Termination Date,
without any further action by Borrower or such Bank; provided that no such
                                                     --------
extension shall be effective unless the Commitments of Banks agreeing to so
extend the Termination Date plus the Commitments of any New Banks which have
agreed to become party to this Agreement pursuant to Section 11.18 constitute at
least 50% of the Total Commitment existing on the date hereof.

     (c)  If any Bank does not consent to a request for an extension of the
Termination Date, or is deemed not to have consented to the requested extension,
and the Termination Date has been extended for the other Bank(s): (i) the
Borrower may, prior to the end of the non-extended Termination Date, terminate
such Bank's Commitment under this Agreement upon payment in full of principal
and interest on all Loans made by such Bank together with such other sums, if
any, that may be due by reason of such prepayment and any fees owing to such
Bank and, in connection with such termination, the Borrower may replace such
non-consenting Bank with a New Bank or increase the Commitment of an existing
Bank, in each case pursuant to Section 11.18; and (ii) if the Borrower has not
previously terminated such non-consenting Bank's Commitment under this Credit
Agreement and paid principal and interest on the Loans held by such non-
consenting Bank and other amounts due to such non-consenting Bank as provided
above, then such principal and interest and other amounts due to such non-
consenting

                                     -17-
<PAGE>

Bank shall be due and payable on the non-extended Termination Date and the
Termination Date shall not be extended insofar as such non-consenting Bank is
concerned.

                                   SECTION 3
                        PAYMENT OF COSTS AND REDUCTION
                               OF THE COMMITMENT

     3.1  Indemnification Upon Failure to Pay Eurodollar Loan or Bid Rate Loan.
          --------------------------------------------------------------------
If Borrower makes any payment of principal with respect to any Eurodollar Loan
or Bid Rate Loan on a day other than the last day of the then current Interest
Period applicable to such Loan (including without limitation any payment upon
reduction of the Commitments) or fails to borrow, continue, convert, pay or
prepay its Eurodollar Loan or Bid Rate Loan on a date designated to
Administrative Agent in a notice pursuant to this Agreement (if such failure
does not result from the application of Sections 4.1 or 4.2), Borrower shall
reimburse each Bank within 15 days after receipt of written demand for any loss
incurred by it as a result of the timing of such payment or non-borrowing not
reflected in the Eurodollar Rate or the Bid Rate, including without limitation
any loss incurred in liquidating or employing deposits from third parties and
loss of profit for the period after such payment or non-borrowing.  A
certificate of such Bank setting forth the amounts reasonably necessary so to
reimburse it in respect of any loss shall be conclusive and binding absent
manifest error.

     3.2  Increased Costs.  (a) If after the date hereof, any applicable law,
          ---------------
rule or regulation or any change therein or 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 Bank (or its Lending Office) with any request or directive of any such
authority, central bank or comparable agency, whether or not having the force of
law, shall impose, modify or deem applicable:

          (i)    any reserve (including, without limitation, any imposed by the
     Board of Governors of the Federal Reserve System), special deposit,
     compulsory loan or similar requirements against assets, commitments or
     deposits or other liabilities with, of or for the account of, or credit
     extended by, or any acquisition of funds by or for the account of any Bank
     or its Lending Office or the London interbank market or any other condition
     affecting its obligations to make the Loans to Borrower hereunder;

          (ii)   any capital or similar requirements against (or against any
     class of or change in or the amount of) assets or liabilities of, or
     commitments or extensions of credit by, such Bank;

each Bank which is so affected shall give prompt notice to Borrower describing
such reserves or requirements at least four Business Days prior to the date such
Bank will begin to implement such additional charges with respect to Borrower.
If the result of any of the foregoing is to increase the cost or reduce the
profit to such Bank (or its Lending Office) under this Agreement by an amount
deemed by such Bank to be material, then, within 15 days after written demand by
such Bank, Borrower will pay to such Bank such additional amount or amounts as
will compensate such Bank for such increased cost incurred or reduction in
profit suffered by such Bank.  Such Bank will designate a different Lending
Office if such designation will avoid the

                                     -18-
<PAGE>

need for, or reduce the amount of, such compensation and will not be otherwise
disadvantageous to such Bank in the sole discretion of such Bank. A certificate
of such Bank setting forth the basis for determining such additional amount or
amounts necessary to compensate the Bank shall be conclusive in the absence of
manifest error.

     (b)  Without limiting the effect of the foregoing (but without
duplication), upon any Bank's prior written request, Borrower shall pay to such
Bank on the last day of each Interest Period, so long as such Bank may be
required to maintain reserves against "eurocurrency liabilities" under
Regulation D (as at any time amended) of the Board of Governors of the Federal
Reserve System, as additional interest on the unpaid principal amount of each
Eurodollar Loan by such Bank outstanding during such Interest Period, an
additional amount (determined by such Bank and notified to Borrower in writing)
up to but not exceeding such amount as would, together with payments of interest
on such Eurodollar Loan for such Interest Period, result in the receipt by such
Bank of total interest on such Eurodollar Loan, for such Interest Period at a
rate determined by such Bank to be equal to the sum of:

          (i)    the Eurodollar Rate divided by a sum equal to (a) 1 minus (b)
     the rate (expressed as a decimal) of such reserves required by Regulation
     D, plus

          (ii)   the Applicable Amount for Eurodollar Loans.

     In determining the additional amount payable for an Interest Period
pursuant to this Section, such Bank shall take into account any transitional
adjustment or phase-in provisions of such reserve requirements applicable during
such Interest Period, which would reduce the reserve requirement otherwise
applicable to eurocurrency liabilities during such Interest Period; provided,
however, each Bank in its sole discretion may determine the allocation of
reserve requirements to its Eurodollar Loans.  Each such determination made by
such Bank, and each such notification by such Bank to Borrower under this
Section, shall be conclusive as to the matters set forth therein in the absence
of manifest error.

     3.3  Taxes.  All payments or reimbursements under this Agreement and any
          -----
instrument or agreement required hereunder shall be made without setoff or
counterclaim and free and clear of and without deduction for any and all present
and future Taxes.  Borrower agrees to cause all such Taxes to be paid on behalf
of any Bank or Administrative Agent directly to the appropriate Governmental
Authority.  If Borrower is legally prohibited from complying with this
subsection, payments due to such Bank or Administrative Agent under this
Agreement and any instrument or agreement required hereunder shall be increased
so that, after provisions for Taxes and all Taxes on such increase, the amounts
received by such Bank or Administrative Agent will be equal to the amounts
required under this Agreement and any instrument or agreement required hereunder
as if no Taxes were due on such payments.  Borrower shall indemnify each Bank
and Administrative Agent for the full amount of Taxes payable by such Bank or
Administrative Agent and any liabilities (including penalties, interest and
expenses) arising from such Taxes within 30 days from any written demand by such
Bank.  Borrower shall provide evidence that all applicable Taxes have been paid
to the appropriate taxing authorities by delivering to Administrative Agent
official tax receipts or notarized copies or other evidence thereof satisfactory
to Administrative Agent, within 90 days after the due date for such Tax payment.
Such Bank will designate a different Lending Office if such designation will
avoid the

                                     -19-
<PAGE>

need for, or reduce the amount of, such payment or reimbursement and will not be
otherwise disadvantageous to such Bank in the sole discretion of such Bank.

     3.4  Prepayment.  Upon the irrevocable written notice of Borrower received
          ----------
by Administrative Agent by 11:00 a.m. California time at least one Business Day
prior to the prepayment of a Base Rate Loan and at least five Eurodollar Banking
Days prior to the prepayment of a Eurodollar Loan, Borrower may prepay any
Eurodollar Loan or Base Rate Loan; but such prepayment shall be in an amount of
at least $5,000,000 or multiple integrals of $1,000,000 in excess thereof.  The
notice of prepayment shall specify the date of the prepayment, the amount of the
prepayment and the Loan to be prepaid.  Each such prepayment shall be made on
the date specified and, in the case of a prepayment of any Eurodollar Loan shall
be accompanied by the payment of accrued interest on the amount prepaid.
Subject to compliance with the foregoing procedures, Base Rate Loans may be
prepaid at any time without cost or penalty of any kind.  If Borrower elects to
prepay a Eurodollar Loan, Borrower shall, on demand by each Bank, pay such Bank
the amount (if any) by which (a) the additional interest which would have been
payable on the amount prepaid on such Bank's portion of such Loan had it not
been paid until the last day of the Interest Period of such Loan exceeds (b) the
interest which would have been recoverable by such Bank by placing such prepaid
amount on deposit in the offshore Dollar interbank markets for a period starting
on the date on which it was prepaid and ending on the last day of the Interest
Period for such Loan.  Bid Rate Loans may not be prepaid.

     3.5  Pro Rata Reduction of Commitments by Borrower.  Borrower may, upon
          ---------------------------------------------
five Business Days' prior written notice (which notice shall be irrevocable) to
Banks through Administrative Agent, reduce the Total Commitment on a pro rata
basis among the Banks.  Such a reduction shall be in an amount of at least
$5,000,000 or multiple integrals of $1,000,000 in excess thereof.  Borrower
shall, on the effective date of each such reduction, repay to each Bank through
Administrative Agent that portion of each Loan which exceeds the amount of each
Bank's Commitment as reduced, together with accrued interest on the amount paid
and accrued facility fees subject to such reduction.  After the effective date
of each reduction, the Banks' obligations under this Agreement shall be based on
the reduced Commitments.

     3.6  Reduction of One Bank's Commitment by Borrower.  If the amount of any
          ----------------------------------------------
payment to be made to or for the account of any Bank is increased under Section
3.3 or any Bank makes a claim under Section 3.2, then:

     (a)  Borrower may, within 60 days after the notice thereof and by not less
than five Business Days' written notice to Administrative Agent, cancel such
Bank's Commitment, whereupon such Bank shall cease to be obligated to
participate in further Loans hereunder and its Commitment shall be reduced to
the amount of its outstanding Loans until such Loans are repaid by Borrower
either on the Principal Repayment Date for such Loans or pursuant to Section
3.6(b), at which time such Bank's Commitment shall be reduced to zero;

     (b)  if Borrower cancels such Bank's Commitment pursuant to clause (a)
above and if Borrower so elects by written notice to Administrative Agent given
at the same time as the notice referred to in clause (a) above, Borrower shall
prepay such Bank's portion of each outstanding Loan together with any accrued
interest thereon plus all costs and expenses (including break and funding costs
in connection with the relending, reborrowing, funding or other employing of

                                     -20-
<PAGE>

funds) incurred by such Bank as a result of such cancellation or prepayment on a
date other than the Principal Repayment Date for such Loan; and

     (c) Borrower shall repay all Bid Rate Loans from such Bank on the
Principal Repayment Date for such Loans and shall not request any additional Bid
Rate Loans from such Bank.

     3.7  Notice of Reductions.  Each notice of reduction or prepayment given
          --------------------
pursuant to Section 3.4, 3.5 or 3.6 shall be irrevocable, shall specify the date
upon which such reduction or prepayment is to be made and, in the case of a
notice of prepayment, shall obligate Borrower to make such prepayment on such
date.  Borrower may not give a notice of reduction of a part of the Commitment
pursuant to Section 3.6 at any time prior to the date so specified in any
previous such notice.

     3.8  Designation of Replacement Bank.  If the Commitment of any Bank is
          -------------------------------
cancelled by Borrower pursuant to Section 3.6 or if any Bank terminates its
Commitment with respect to Eurodollar Loans pursuant to Section 4.2, Borrower,
with the consent of Administrative Agent, may designate an Eligible Assignee
(or, if it deems appropriate, more than one Eligible Assignee) acceptable to
Administrative Agent to act as a Bank hereunder and upon execution of a written
agreement in form satisfactory to Administrative Agent by such Eligible Assignee
in which it agrees to abide by all of the terms, conditions and obligations
applicable to a Bank herein and to have a Commitment as specified in such
agreement, such Eligible Assignee shall be deemed a Bank hereunder to the same
extent as if it were a signatory hereto and, thereafter, such Eligible Assignee
shall for all purposes be considered a "Bank" hereunder.

     3.9  Effect of Reduction of Commitment.  If, at any time:
          ---------------------------------

     (a) the Commitment of any Bank is reduced to zero in accordance with the
terms of this Agreement;

     (b) all indebtedness and other amounts owed to such Bank by Borrower
hereunder or in connection herewith have been satisfied in full; and

     (c) such Bank is under no further actual or contingent obligation
hereunder,

then such Bank shall cease to be a party hereto and a Bank for the purposes
hereof; provided, however, that the obligations of Borrower under Sections 3.1,
        --------  -------
3.2, 3.3, 11.14, 11.15 and 11.16 shall survive the cancellation of the
Commitment and the termination of this Agreement.

     3.10 Accrued Fees.  On the date of the cancellation of any portion of the
          ------------
Total Commitment in accordance with Section 3.5 or of any Bank's Commitment
under Section 3.6, all accrued facility fees for such portion of the Total
Commitment or of such Bank's Commitment shall be paid in full by Borrower.

     3.11 Survival.  The agreements and obligations of Borrower in this Section
          --------
3 shall survive the termination of this Agreement.

                                     -21-

                                   SECTION 4
                    CHANGE IN CIRCUMSTANCES AFFECTING LOANS

     4.1  Inability to Determine Eurodollar Rate.  If any Reference Bank
          --------------------------------------
determines (which determination shall be made in good faith and shall be
conclusive and binding upon Borrower) that (a) by reason of circumstances then
affecting the Eurodollar interbank market, adequate and reasonable means do not
or will not exist for ascertaining the interest rate applicable to any
Eurodollar Loans, or (b) Dollar deposits in the relevant amounts and for the
relevant Interest Period are not available to the Banks in the Eurodollar
interbank market, then it shall notify the Administrative Agent who shall
forthwith give written notice of such determination to Borrower and each Bank at
least one Business Day prior to the first day of any Interest Period so
affected; whereupon, until Administrative Agent shall notify Borrower that the
circumstances giving rise to such suspension no longer exist, (i) the
obligations of the Banks to make Eurodollar Loans shall be suspended and (ii)
Borrower shall repay in full, without premium or penalty, the then outstanding
principal amount of the Eurodollar Loans, together with accrued interest
thereon, on the last day of the then current Interest Period pursuant to the
next sentence.  Unless Borrower notifies Administrative Agent to the contrary
within one Business Day after receiving a notice from Administrative Agent
pursuant to this Section, Borrower shall, concurrently with prepaying the
Eurodollar Loans pursuant to this Section, be deemed automatically without any
further notice to Administrative Agent or the Banks to have requested and
received Base Rate Loans in an equal principal amount from the Banks, the
proceeds of which are deemed to have been used to repay the other Loans.

     4.2  Illegality.  If, after the Effective Date, the introduction of or any
          ----------
change in any applicable law, rule or regulation or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof or compliance by any Bank with any
request or directive (whether or not having the force of law) of any such
authority shall make it unlawful or impossible for such Bank (or its Lending
Office) to make, maintain or fund its Eurodollar Loans, such Bank shall
forthwith give written notice thereof to Administrative Agent and to Borrower.
Before giving any notice pursuant to this Section, such Bank shall designate a
different Lending Office if such designation will avoid the need for giving such
notice and will not be otherwise disadvantageous to such Bank in the sole
judgment of such Bank.  Upon receipt of such notice (a) if such Bank has
received a request with respect to Eurodollar Loans and has not yet made such
Loan, a Base Rate Loan shall be deemed to have been designated without any
further notice; (b) all Loans which would otherwise be made by such Bank as
Eurodollar Loans shall be made instead as Base Rate Loans; and (c) Borrower
shall prepay in full, without premium or penalty, the then outstanding principal
amount of such Bank's Eurodollar Loans, together with accrued interest, on
either (i) the last day of the then-current Interest Period if such Bank may
lawfully continue to fund and maintain such Eurodollar Loans, to such day or
(ii) immediately if such Bank may not lawfully continue to fund and maintain
such Eurodollar Loans to such day together with an amount, if any, calculated as
set forth in the last sentence of Section 3.4.  Concurrently with prepaying each
such Eurodollar Loan Borrower shall borrow a Base Rate Loan from such Bank in an
amount equal to the principal amount of such Bank's Eurodollar Loans, the
proceeds of which are deemed to have been used to repay such Bank's Eurodollar
Loans.  If circumstances subsequently change so that such Bank is not further
affected, and no Eligible Assignee has been appointed pursuant to Section 3.8,
such Bank
                                     -22-
<PAGE>

shall so notify Borrower and Administrative Agent and such Bank's obligation to
make and continue Eurodollar Loans shall be reinstated upon written request of
Borrower.

                        REPRESENTATIONS AND WARRANTIES

     6.   Borrower represents and warrants that as of the Effective Date:

     6.1  Authority of Borrower.  Borrower (a) is a corporation duly organized
          ---------------------
and existing under the laws of the State of Delaware, with its principal place
of business in Los Angeles County, California, (b) has the corporate power to
own its property and carry on its business as now being conducted, (c) is duly
qualified and authorized to do business, and is in good standing in every state,
country or other jurisdiction where the failure to be so qualified, authorized
and in good standing would have a material adverse effect on Borrower, (d) has

execute, deliver and perform this Agreement and any instrument or agreement
required hereunder, and to perform and observe the terms and provisions hereof
and thereof, (e) has taken all corporate action on the part of Borrower, its

and performance of this Agreement, and any instrument or agreement required
hereunder on the date hereof, (f) requires no consent or approval of any trustee
or holder of any indebtedness or obligation of Borrower to enter into, deliver
or perform its obligations under this Agreement and the Notes, and (g) requires
no consent, permission, authorization, order or license of any Governmental

Agreement and any instrument or agreement required hereunder, or any transaction
contemplated hereby, except as may have been obtained and certified copies of
which have been delivered to Banks through Administrative Agent.

                                     -24-
<PAGE>

     6.2  Binding Obligations.  This Agreement is the legal, valid and binding
          -------------------
obligation of Borrower, enforceable against it in accordance with its terms, and
any instrument or agreement required hereunder, when executed and delivered,
will be similarly valid, binding and enforceable.

     6.3  Incorporation of Restricted Subsidiaries.  Each Restricted Subsidiary
          ----------------------------------------
of Borrower is a corporation duly incorporated, validly existing and in good
standing under the laws of the jurisdiction of its incorporation and, to the
best of Borrower's knowledge, is duly licensed or qualified as a foreign
corporation in all jurisdictions where the failure to be so qualified,
authorized and in good standing would have a material adverse effect on Borrower
and its Restricted Subsidiaries taken as a whole.

     6.4  No Contravention.  There is no charter, by-law, or capital stock
          ----------------
provision of Borrower  and no provision of any indenture or material agreement,
written or oral, to which Borrower is a party or under which Borrower is
obligated, nor is there any statute, rule or regulation, or any judgment, decree
or order of any court or agency binding on Borrower which would be contravened
by the execution, delivery and performance of this Agreement, or any instrument
or agreement required hereunder, or by the performance of any provision,
condition, covenant or other term hereof or thereof.

     6.5  Notices.  Except as previously disclosed in writing to Administrative
          -------
Agent, no event has occurred which, to the best of its knowledge, would require
Borrower to notify Administrative Agent and the Banks pursuant to Section 7.3
hereof.

     6.6  Financial Statements.  The audited consolidated financial statements
          --------------------
dated December 31, 1998 and the unaudited consolidated financial statements for
the six months ended June 30, 1999 furnished by Borrower to the Administrative
Agent and Banks, present fairly the financial position and results of operation
and changes in financial position of Borrower and its consolidated Subsidiaries
as at the end of, and for the fiscal periods to which such statements relate,
and such financial statements were prepared in accordance with GAAP.  Since June
30, 1999, there has been no Material Adverse Change.  The Borrower and its
Subsidiaries did not have any contingent obligations, liabilities for taxes or
other outstanding financial obligations at June 30, 1999 which are material in
the aggregate for Borrower and its Subsidiaries, taken as a whole, except as
disclosed in such unaudited consolidated financial statements.

     6.7  ERISA.  Based upon ERISA and the regulations and published
          -----
interpretations thereunder, the Plans of Borrower and its Subsidiaries and, to
the knowledge of Borrower, the Plans of any other ERISA Affiliates, are in
material and substantial compliance in all material respects with the applicable
provisions of ERISA and Borrower and its Subsidiaries are in compliance with
such Plans in all material respects.  No Reportable Event which has or could be
reasonably be expected to result in termination thereof by the Pension Benefit
Guaranty Corporation or for the appointment by the appropriate United States
District Court of a trustee to administer such Plan has occurred and is
continuing with respect to any Plan.

     6.8  Regulation U; Investment Company Act.  Borrower is not engaged
          ------------------------------------
principally, or as one of its important activities, in the business of extending
credit for the purposes of purchasing or carrying any "margin stock" within the
meaning of Regulation U of the Board of
<PAGE>

Governors of the Federal Reserve System; and neither Borrower nor any of its
Subsidiaries is an "investment company" within the meaning of the Investment
Company Act of 1940.

     6.9  Taxes.  Borrower has filed all federal and state tax returns which to
          -----
the knowledge of the financial officers of Borrower are required to have been
filed, and has paid prior to delinquency all taxes that have become due pursuant
to said returns or pursuant to any assessment, except as are being contested in
good faith by appropriate proceedings and as to which adequate reserves have
been provided on the books of Borrower in accordance with GAAP.

     6.10 Insurance.  Borrower and its Restricted Subsidiaries maintain
          ---------
insurance with responsible insurance companies, in such amounts and against such
risks as is customarily carried by owners of similar businesses and property,
including protection against loss of use and occupancy, to the extent such
insurance is reasonably available at commercially reasonable rates, and it will
furnish Administrative Agent, upon written request, with full information as to
the insurance carrier; provided, however, that Borrower and its Restricted
                       --------  -------
Subsidiaries may self insure to the extent they deem prudent.

     6.11 Liens.  The properties and assets of Borrower and its Restricted
          -----
Subsidiaries, real, personal and mixed, are not subject to any Liens, except for
Liens permitted by this Agreement.

     6.12 Litigation.  Except as disclosed in writing to the Banks prior to the
          ----------
Signing Date, no litigation, investigation or proceeding of or before an
arbitrator or Governmental Authority is pending or, to the knowledge of Borrower
after due and diligent investigation, threatened by or against Borrower or any
of its Subsidiaries or against any of their properties or revenues which could
reasonably be expected to cause a Material Adverse Change.

     6.13 Environmental Compliance.  Borrower and its Subsidiaries each conduct
          ------------------------
in the ordinary course of business a review of the effect of existing
Environmental Laws and claims alleging potential liability or responsibility for
violation of any Environmental Law on their respective businesses, operations
and properties, and as a result thereof Borrower has reasonably concluded that
such Environmental Laws and claims could not, individually or in the aggregate,
reasonably be expected to cause a Material Adverse Change.

     6.14 Year 2000.  Borrower has (a) completed a review and assessment of all
          ---------
areas within its and each of its Subsidiaries' business and operations
(including those affected by customers and vendors) that could be adversely
affected by the "Year 2000 Problem" (that is, the risk that computer
applications and devices containing imbedded computer chips used by Borrower or
any of its Subsidiaries may be unable to recognize and perform properly date-
sensitive functions involving certain dates prior to and any date after December
31, 1999), (b) developed a plan and timeline for addressing the Year 2000
Problem on a timely basis, and (c) to date, implemented that plan in accordance
with that timetable.  Based on the foregoing, Borrower believes that all
computer applications and devices containing imbedded computer chips that are
material to its or any of its Subsidiaries' business and operations are
reasonably expected on a timely basis to be able to perform properly date-
sensitive functions for all dates before and after January 1, 2000 (that is, be
"Year 2000 compliant"), except to the extent that a failure to do so could not
reasonably be expected to cause a Material Adverse Change.

                                     -26-
<PAGE>

     6.15 Disclosure.  No written statement (or oral statement made by senior
          ----------
executives of Borrower at the bank meeting held on November 3, 1999, it being
understood that any projections contained in such statements are not to be
viewed as facts but were based on good faith estimates and assumptions believed
by Borrower to be reasonable), written information, report, representation, or
warranty made by Borrower in this Agreement or furnished to Administrative Agent
or any Bank in connection with this Agreement contains any untrue statement of a
material fact or omits to state any material fact necessary to make the
statements herein or therein not misleading.

(who shall promptly notify the Banks) of:

terms or provisions of this Agreement;

     (b)  any event of default under any other agreement, contract, indenture,
document or instrument entered, or which may be entered, into by it that could,
if settled unfavorably, result in a Material Adverse Change;

     (c)  all material changes in senior management publicly announced;

     (h)  promptly upon any discovery or determination that any computer

Adverse Change.

     America or any state thereof, or in favor of any other country, or any
     political subdivision thereof, to secure partial, progress, advance or
     other payments pursuant to any contract or statute or to secure any
     indebtedness incurred for the purpose of financing all or any part of the
     purchase price or the cost of construction of the property subject to such
     Liens; or

          (7) any extension, renewal or replacement (or successive extensions,
     renewals or replacements) in whole or in part of any Liens referred to in
     the foregoing sub-clauses (1) to (6), inclusively; provided, however, that

          ---------------------------
as one of its important activities, in the business of extending credit for the
purposes of purchasing or carrying any "margin stock" within the meaning of

Default shall exist hereunder if the aggregate amount of the indebtedness which
is not paid or may be accelerated with respect to the defaulted obligations
shall not exceed in the aggregate $75,000,000; or

any reason other than the agreement of all Banks or satisfaction in full of all
the duties and obligations hereunder, ceases to be in full force and effect or
is declared by a court of competent jurisdiction to be null and void, invalid or
unenforceable in any respect; or Borrower denies that it has any or further

9.1(d), the Commitments shall immediately terminate, and all Loans and other
liabilities and obligations outstanding under this Agreement shall, without
presentment, demand, protest, or notice of any kind, all of which are hereby

occurrence of an Event of Default other than under Section 9.1(d), and in each
and every such case, unless such Event of Default shall have been remedied by
Borrower to the satisfaction of Majority Banks or waived in writing by Majority
Banks (except in the case of an Event of Default under  Section 9.1(a), the
waiver of which shall require the consent of all the Banks), Administrative
Agent may, with the consent of the Majority Banks, or shall, upon the direction
of Majority Banks, immediately terminate the Commitments, whereupon the same
shall be cancelled and reduced to zero and any Loan Request given in respect of
a Borrowing Date occurring on or after the date of such notice of cancellation
shall cease to have effect and all Loans and all accrued interest thereon and
all other liabilities and obligations outstanding under this Agreement shall,
thereupon, without presentment, demand, protest, or notice of any kind, all of
which are hereby expressly waived, be forthwith due and payable, if not
otherwise then due and payable, together with all reasonable costs and expenses
(including break and funding costs and other costs in connection with the
relending, reborrowing, funding or other employing of funds) incurred by the

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

their respective affiliates to proceed, to the fullest extent permitted by
applicable law, without prior notice, by right of set-off, banker's lien or
counterclaim, against any moneys or other assets of Borrower in any currency
that may at any time be in the possession of Administrative Agent or any of its
affiliates or such Bank or any of its affiliates, at any branch or office
thereof, to the full extent of all amounts payable to Administrative Agent and

          -----------------
provided for herein are cumulative and are not exclusive of any other rights,

any provision herein providing for consent or other action by all Banks;
provided, further, that no amendment, waiver or consent shall, unless in writing
--------  -------
and signed by Administrative Agent in addition to Majority Banks or all Banks,
as the case may be, affect the rights or duties of Administrative Agent under
this Agreement or rights or privileges thereunder.

     11.2 Notices.  All notices, payments, requests, reports, information,
          -------
demands and other communications which any party hereto may desire, or may be
required, to give or make to any other party hereto, shall (unless otherwise
permitted as a telephonic notice or request hereunder) be given by mailing the
same, postage prepaid, or by telex, or rapifax transmission, or by hand delivery
or courier, to each party at its address set forth in Exhibit D attached hereto
and incorporated herein by reference, or to such other address as may, from time
to time, be specified in writing by Borrower or any Bank.  Such communications
shall be deemed to have been duly given and received in the case of a telex,
when the telex is sent and the appropriate answer-back

                                     -37-
<PAGE>

is received, in the case of mail when sent by pre-paid certified or registered
mail correctly addressed to the addressee, in the case of rapifax transmission,
when transmission has been sent, and in the case of hand delivery or courier,
when received. Administrative Agent may rely and act upon any Loan Request made
by telex or other telexed, telephonic or facsimile instructions to
Administrative Agent by any Person purporting to be an authorized Person of
Borrower, and Borrower shall be unconditionally and absolutely estopped from
denying the authenticity and validity of any transaction or act made by
Administrative Agent or any Bank in reliance thereon. Each party hereto shall
promptly confirm by telex or rapifax any telephone communication made by it to
another pursuant to this Agreement but the absence of such confirmation shall
not affect the validity of such communication, which shall be effective upon
receipt. If there is any conflict between any telephonic communication and a
written confirmation, the written communication shall govern; provided, however,
                                                              --------  -------
that the recipient of such communication shall be held harmless by all parties
hereto with respect to any action taken in reliance on the telephonic
communication prior to the time such recipient receives and has had reasonable
time to review the subsequent written confirmation and initiate such corrective
action as the recipient deems reasonable under the circumstances.

     11.3 Waiver.  Neither the failure of, nor any delay on the part of, any
          ------
party hereto in exercising any right, power or privilege hereunder, or under any
agreement, contract, indenture, document or instrument mentioned herein, shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege hereunder, or under any agreement, contract,
indenture, document or instrument mentioned herein, preclude other or further
exercise thereof or the exercise of any other right, power or privilege; nor
shall any waiver of any right, power, privilege or default hereunder, or under
any agreement, contract, indenture, document or instrument mentioned herein,
constitute a waiver of any other right, power, privilege or default or
constitute a waiver of any other default of the same or of any other term or
provision.  All rights and remedies herein provided are cumulative and not
exclusive of any rights or remedies otherwise provided by law.

     11.4 California Law.  The interpretation, enforcement and effect of this
          --------------
Agreement, the Loans and any agreements, contracts, indentures, documents or
instruments delivered in accordance herewith, shall be governed and controlled
in all respects by and construed according to the substantive laws of the State
of California, to the jurisdiction of whose courts the parties hereto hereby
agree to submit.

     11.5 Headings.  The headings set forth herein are solely for the purpose of
          --------
identification and shall not be construed as a part of the sections or
subsections which they head.

     11.6 Accounting Terms.  All accounting terms not otherwise defined herein
          ----------------
have the meaning assigned to them in accordance with GAAP, provided, however,
any act or condition in accordance herewith and permitted hereunder when taken,
created or occurring, shall not become a violation of any section of this
Agreement as a result of a subsequent change in GAAP.

     11.7 Counterparts.  This Agreement may be executed in any number of
          ------------
counterparts and by the different parties hereto on separate counterparts, and
all of said counterparts taken together shall constitute one and the same
instrument.

<PAGE>

     11.8  Written Disclosure. Wherever written disclosure by Borrower to Banks
           ------------------
is required or permitted by this Agreement, written disclosure to Administrative
Agent by Borrower shall constitute such disclosure.

     11.9  Singular; Plural.  Whenever used herein, the singular number shall
           ----------------
include the plural, the plural the singular, and the use of any gender shall be
applicable to all genders.

     11.10 Illegality.  The illegality or unenforceability of any provision of
           ----------
this Agreement or any instrument or agreement required hereunder shall not in
any way affect or impair the legality or enforceability of the remaining
provisions of this Agreement or any instrument or agreement required hereunder.

     11.11 Assignments.  This Agreement shall bind and inure to the benefit of
           -----------
the parties hereto and their respective successors and assigns.  No party hereto
may assign or transfer all or any part of its rights and obligations hereunder,
except that:

     (a) Any Bank may, with the prior written consent of Borrower at all times
other than during the existence of an Event of Default, and Administrative
Agent, which consents shall not be unreasonably withheld, at any time assign and
delegate to one or more Eligible Assignees (provided that no written consent of
                                            --------
Borrower or the Administrative Agent shall be required in connection with any
assignment and delegation by Bank to an Approved Bank Affiliate of such Bank or
another Bank) (each an "Assignee") by execution and delivery to, and acceptance
by, the Administrative Agent of a Notice of Assignment and Acceptance, all, or
any ratable part of all, of the Loans, the Commitments and the other rights and
obligations of such Bank hereunder; provided, however, that any assignment to an
                                    --------  -------
Eligible Assignee which is not a Bank or an Approved Bank Affiliate shall be in
an amount not less than the lesser of $5,000,000 or all, but not less than all,
of the Loans, the Commitment and the other rights and obligations of such Bank
hereunder.  Upon execution of a Notice of Assignment and Acceptance by such
Eligible Assignee in which it agrees to abide by all of the terms, conditions
and obligations applicable to a Bank herein and to have a Commitment as
specified in such agreement, such Eligible Assignee shall be deemed a Bank
hereunder to the same extent as if it were a signatory hereto and, thereafter,
such Eligible Assignee shall for all purposes be considered a "Bank" hereunder.
Administrative Agent shall be entitled to a $2,500 processing fee, payable by
the assignor, with respect to any such assignment by a Bank.

     (b) Subject to Section 11.16, Borrower authorizes each Bank and the
Arrangers to disclose to any prospective assignee and assignee any and all
information in such Bank's or the Arrangers' possession concerning Borrower,
this Agreement and any collateral.

     (c) Notwithstanding anything to the contrary contained herein, any Bank (a

"Granting Bank") may grant to a special purpose funding vehicle (an "SPC"),
 -------------                                                       ---
identified as such in writing from time to time by the Granting Bank to
Administrative Agent and Borrower, the option to provide to Borrower all or any
part of any Loan that such Granting Bank would otherwise be obligated to make to
the Borrower pursuant to this Agreement; provided that (i) nothing herein shall
                                         --------
constitute a commitment by any SPC to make any Loan, (ii) if an SPC elects not
to exercise such option or otherwise fails to provide all or any part of such
Loan, the Granting Bank shall be obligated to make such Loan pursuant to the
terms hereof.  The making of a Loan by an SPC

                                     -39-
<PAGE>

hereunder shall utilize the Commitment of the Granting Bank to the same extent,
and as if, such Loan were made by such Granting Bank. Each party hereto 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
Granting Bank). In furtherance of the foregoing, each party hereto hereby 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 commercial paper or other senior indebtedness of any SPC, it will
not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings under the laws of the United States or any State thereof. In
addition, notwithstanding anything to the contrary contained in this Section,
any SPC may (i) with notice to, but without the prior written consent of,
Borrower and Administrative Agent and without paying any processing fee
therefor, assign all or a portion of its interests in any Loans to the Granting
Bank or to any financial institutions (consented to by Borrower and
Administrative Agent) providing liquidity and/or credit support to or for the
account of such SPC to support the funding or maintenance of Loans and (ii)
subject to the provisions of Section 11.16 hereof, disclose on a confidential
basis any non-public information relating to its Loans to any rating agency,
commercial paper dealer or provider of any surety, guarantee or credit or
liquidity enhancement to such SPC. This section may not be amended without the
written consent of the SPC.

     11.12 Obligations Several.  The obligations of each Bank under this
           -------------------
Agreement are several.  Neither Administrative Agent nor any Bank shall be
liable for the failure of any other Bank to perform its obligations under this
Agreement.

     11.13 Participations.  Any Bank may at any time sell, or grant
           --------------
participations in all or part of its Commitment or any Loan or Loans made to
Borrower under this Agreement to any other Person, other than an individual, (a
"Participant"); provided, however, no Bank may be relieved of its obligations
under this Agreement except with the consent of Borrower and Administrative
Agent.  Any such sale or grant of a participation is subject to the following
conditions:

     (a) Administrative Agent and Borrower may, for all purposes of this
Agreement, deem and treat a Bank party to this Agreement as the owner of such
Bank's Loans hereunder for all purposes hereof until a written notice of the
sale or participation shall have been received by Administrative Agent, together
with Borrower's consent to treat such Participant as owner of such Loan.

     (b) Subject to Section 11.16, Borrower authorizes each Bank and the
Administrative Agent to disclose to any prospective Participant and to any
Participant any and all information in such Bank's or the Administrative Agent's
possession concerning Borrower, this Agreement and any collateral.

     (c) Any agreement pursuant to which a Bank grants a participation in its
rights with respect to any Loan or Loans shall provide that, with respect to any
such Loan or Loans, such Bank shall retain the sole right and responsibility to
exercise the rights of a Bank under this Agreement including, without
limitation, the right to approve any amendment, modification or waiver of any
provision of this Agreement and the right to take action to declare any amount
due

                                     -40-
<PAGE>

and payable pursuant to Section 9; provided that such participation agreement
may provide that such Bank will not agree to any modification, amendment or
waiver of this Agreement without the consent of the Participant if such
modification, amendment or waiver would (i) increase the amount of the Total
Commitment or change the Commitment of such Bank, (ii) reduce interest,
principal or fees owing to such Bank hereunder, (iii) extend the fixed date on
which any sum is due hereunder, or (iv) release or subordinate any material
portion of collateral.

     (d) Except as provided in this Section 11.13, no recipient of a
participation in a Loan or Loans of any Bank shall have any rights under this
Agreement other than to receive payment of principal of, and interest on the
Loans and of such other amounts as Banks are entitled to receive pursuant to
Sections 3.1, 3.2, 3.3, and 3.4 of this Agreement; provided, however such
recipients shall be entitled to receive pursuant to Sections 3.1, 3.2 and 3.3
only the lesser of (i) the amount that the Bank from which the recipient
received its participation would have received had such Bank not transferred an
interest in its Loans to such recipient and (ii) the additional costs actually
incurred by such recipient; and any demand by a Participant for payment
hereunder shall certify that the amount demanded does not exceed the amount
Participant is entitled to receive under this subsection (d).

     (e) Notwithstanding any other provision set forth in this Agreement, any
Bank may at any time create a security interest in all or any portion of its
rights under this Agreement (including, without limitation, the Loans owing to
it) in favor of any Federal Reserve Bank in accordance with Regulation A of the
Board of Governors of the Federal Reserve System.

     11.14 Fees and Expenses.  Borrower agrees to pay on demand (a) to
           -----------------
Administrative Agent all reasonable costs, expenses and attorneys' fees
(including allocated costs for in-house legal services) incurred by
Administrative Agent and the Arrangers in connection with the preparation and
administration of this Agreement and any documents including any amendments,
waivers, or other modifications and (b) all reasonable costs, expenses and
attorneys' fees (including allocated costs for in-house legal services) incurred
by Administrative Agent and Banks in connection with the enforcement of this
Agreement and any instrument or agreement required hereunder and in connection
with any refinancing or restructuring of the Loans in the nature of a "work-
out"; provided, however that, in addition to costs of Administrative Agent's in-
house counsel, Borrower shall be obligated to pay for the costs of no more than
one counsel for Administrative Agent and all Banks (without prejudice to any
Bank's right to engage additional counsel at its own cost and expense) unless
any Bank shall in good faith reasonably determine that there is a conflict of
interest that causes it to be reasonably necessary for such Bank to be
represented by separate counsel.

     11.15 Indemnity.  Borrower agrees to indemnify the Administrative Agent,
           ---------
the Arrangers, the Syndication Agent, the Documentation Agents, each Bank and
their respective directors, officers, agents and employees (collectively, the
"Indemnitees") from and hold each of them harmless against any and all losses,
liabilities, claims, damages or expenses, including settlement costs) reasonably
incurred by any of them arising out of or by reason of any investigation by
governmental or judicial authorities or being made a party to any litigation or
other similar proceeding related to any use made or proposed to be made by
Borrower of the proceeds of any Loan for the acquisition of any other Person
(other than with respect to a particular Indemnitee's losses, liabilities,
claims, damages or expenses incurred as a result of

                                     -41-
<PAGE>

such Indemnitee's gross negligence or willful misconduct), including, without
limitation, the reasonable fees and disbursements of counsel (including
allocated costs for in-house legal services) incurred in connection with any
such investigation, litigation or other proceeding; provided, however, that
                                                    --------  -------
Borrower shall have no obligation to indemnify or pay for the costs and expenses
of more than one counsel for the Indemnitees, unless any Indemnitee shall in
good faith reasonably determine that there is a conflict of interest that causes
it to be reasonably necessary for any Indemnitees to be represented by other
counsel. Counsel chosen to represent any Indemnitee pursuant to the previous
sentence shall be reasonably satisfactory to Borrower. The obligations of
Borrower under this Section shall survive the termination of this Agreement.

     11.16 Confidentiality. In consideration of Borrower furnishing Confidential
           ---------------
Information(as defined below) to the Banks, the Arrangers, Administrative Agent,
Syndication Agent and Documentation Agents, (collectively, the "Recipients") and
their respective directors, officers and employees (collectively, the
"Representatives"), each Recipient agrees for itself that:

     (a) Such Recipient shall keep the Confidential Information confidential and
shall not, without Borrower's prior written consent, disclose it in any manner
whatsoever, in whole or in part, and shall not use the Confidential Information
other than in connection with this Agreement.  Each Recipient agrees to reveal
the Confidential Information only to its Representatives, bank affiliates,
auditors, counsel and other advisors, representatives or agents who need to know
the Confidential Information for the purpose of this Agreement, who are informed
by such Recipient of the confidential nature of the Confidential Information and
who shall agree to act in accordance with the terms and conditions of this
section.  Each Recipient shall be responsible for any breach of this Section by
its Representatives.

     (c) Upon payment in full of all obligations owing to a Recipient and
termination of such Recipient's Commitments, if any, hereunder, copies of the
Confidential Information shall be returned by such Recipient to Borrower
immediately upon its request, except for that portion of the information which
consists of analyses, compilations, forecasts, studies or other documents
prepared by such Recipient or its Representatives based on Confidential
Information, which portion shall either be destroyed (as evidenced by a
certificate of destruction signed by a duly authorized offer of such Recipient)
or held by such Recipient and kept confidential and subject to the terms of this
section; provided that such Recipient shall not be required to return or destroy
         --------
Confidential Information to the extent such Recipient reasonably determines that
its retention of such Confidential Information is required by applicable law or
regulation..  Any oral Confidential Information shall continue to be subject to
the terms of this Section.

     (d) Confidential Information shall not include such portions of the
information furnished to a Recipient which (i) are or become generally available
to the public other than as a result of a disclosure by such Recipient or its
Representatives in violation of this Agreement, (ii) become available to such

therein or omissions therefrom.

     (f) In the event any Recipient or any person to whom it transmits the
Confidential Information pursuant to this Agreement becomes legally compelled to
disclose any of the information, such Recipient shall, to the extent permitted
by law, provide Borrower with prompt written notice thereof so that the Borrower
may seek a protective order or other appropriate remedy and/or waiver such
Recipient's compliance with the provisions of this section,  In the event that
such protective order or other remedy is not obtained, or that Borrower waives
any Recipient's compliance with the provisions of this section, such Recipient
may furnish only that portion of the Confidential Information which it is
advised by written opinion of counsel that the disclosure thereof is legally
required, and shall exercise its best efforts to obtain reliable assurance that
confidential treatment will be accorded the Confidential Information so
disclosed.

     (g) Notwithstanding the foregoing, a Recipient may (i) disclose any
Confidential Information to bank examiners; (ii) use any Confidential
Information in connection with the management, supervision and enforcement of
this Agreement, including the enforcement of such Recipient's rights under any
agreement executed in connection therewith; (iii) disclose any Confidential
Information in connection with any litigation or dispute involving any such
Person or the Borrower and related to this Agreement or to any use of proceeds

otherwise reflect such information.

     11.18 New Banks; Increases in Commitments of Banks.  (a) In the event one
           --------------------------------------------
or more Banks do not consent to an extension of the Termination Date pursuant to
Section 2.13, if no Event of Default or Unmatured Event of Default has occurred
and is continuing, Borrower may within five days of Borrower's receipt of notice
of such failure to so extend notify Administrative Agent and the Banks (a
"Commitment Replacement Notice") that (i) it desires to add one or more
additional lenders to the Banks hereunder having aggregate Commitments not
exceeding the Commitment of the Bank(s) which have not consented to an
extension, and/or (ii) with the consent of the relevant Bank(s), increase the
Commitment of any one or more of the Banks in an aggregate amount not exceeding
the Commitment of the Bank(s) which have not consented to an extension of the
Termination Date; provided that the existing Bank(s) shall have the right on a
                  --------
pro rata basis based upon the then existing Commitments to increase their
respective Commitments to replace the terminated Commitments before any New Bank
may be added as a Bank hereunder.  The Banks desiring to increase their
Commitments based upon the immediately preceding proviso must give notice to
Administrative Agent of their intention to accept a greater Commitment within
five days of Borrower's Commitment Replacement Notice.  Each Commitment
Replacement Notice shall identify each new lender (each a "New Bank") proposed
by Borrower to be added as a Bank and/or each existing Bank which has proposed
to increase its Commitment, the amount of its proposed Commitment and the
proposed effective date of its becoming a Bank hereunder or increasing its
Commitment, as applicable (which shall be the last day of all then current
Interest Periods if there are Eurodollar Advances then outstanding from the
Banks). Any increase in the Commitment of a Bank shall be effective upon the
receipt by Administrative Agent of a commitment increase letter in the form of
Exhibit H hereto which shall identify the proposed effective date (which shall
be the last day of all then current Interest Periods if there are Eurodollar
Advances then outstanding from the Banks).  Each New Bank shall, with the
consent of Administrative Agent, become a Bank hereunder for all purposes and to
the same effect as if set forth on the signature pages hereof, subject to its
execution and delivery to Administrative Agent of at least one counterpart of
this Agreement (which shall be deemed to include all amendments thereto) and the
execution and delivery by Administrative Agent and Borrower of each such
counterpart.  Each Bank expressly agrees that its obligations arising hereunder
shall not be affected or diminished by the addition or release of any other Bank
hereunder, nor by any election of Administrative Agent not to authorize a lender
to become a New Bank.

     11.19 (b) Following any Bank's or Banks' refusal to extend their
Commitments pursuant to Section 2.13 herein and/or any subsequent change in the
Commitments of the existing Banks or the addition of a New Bank, Schedule 1 of
this Agreement shall be deemed

                                     -44-
<PAGE>

amended to reflect (i) the termination of the non-extending Bank's Commitment;
(ii) the addition of any New Bank; (iii) such New Bank's Commitment; and (iv)
any change to the Commitment of an existing Bank.

     11.20 (c) Following any Bank or Banks refusal to extend their Commitments
pursuant to Section 2.13 herein and any subsequent change in the Commitments of
the existing Banks or the addition of a New Bank, Borrower agrees to execute
such Notes as necessary to comply with the requirements of Sections 2.8 and 2.9
of this Agreement.

                                   EXHIBIT C
                     RELATIONS AMONG THE BANKS AND AGENTS

     1.   Administration of the Credit.  Payment of interest and principal on
          ----------------------------
the Loans and the facility fee and all other amounts payable by Borrower
hereunder shall be made by Borrower in immediately available funds, directly to
each Bank in the case of amounts payable under Sections 3.1, 3.2 and 3.3 and, in
all other cases, to Administrative Agent, and Administrative Agent shall
promptly distribute to the other Banks in immediately available funds their
shares of principal, interest and fees and to each Bank as provided herein such
other amounts as paid by Borrower.

     2.   Pro Rata Distribution.  All facility fees will be divided among the
          ---------------------
Banks in accordance with their Normal Percentage, and interest and principal
payments on each Loan will be divided pro rata among Banks in accordance with
their percentage interest in the Loan.

     3.   Right of Setoff.  Any Bank which shall receive payment of or on
          ---------------
account of all or part of its share of the Loans through the exercise of any
right of setoff, counterclaim, or banker's lien, or otherwise in a greater
proportion than the proportionate amount of principal and interest due it under
this Agreement immediately prior to such payment shall purchase a ratable
proportion of the portions of the Loan held by the other Banks so that all
recoveries of principal and interest shall be shared by the Banks in accordance
with their pro rata interests in the Loans outstanding hereunder.  If all or any
portion of such excess payment is thereafter recovered from such Bank, such
purchase shall be rescinded and the purchase price restored to the extent of
such recovery, but without interest.  Any sum received by Bank through exercise
of the right of setoff, counterclaim, or banker's lien shall be deemed to be
first applied to such Bank's portion of the indebtedness under this Agreement,
second as herein above provided and any balance remaining thereafter shall be
deemed applied to any other indebtedness of Borrower to such Bank.

     4.   Notice of Event of Default.  Upon receipt by Administrative Agent from
          --------------------------
Borrower of any communication calling for an action on the part of Banks, or
upon notice to Administrative Agent of an Unmatured Event of Default or an Event
of Default, it will in turn promptly inform the other Banks in writing of the
nature of such communication or of the Unmatured Event of Default or Event of
Default, as the case may be.

     5.   Actions by Administrative Agent.  Upon any occasion requiring or
          -------------------------------
permitting an approval, consent, election or other action on the part of Banks,
action shall be taken by Administrative Agent for and on behalf or for the
benefit of all Banks upon the direction of the required number of Banks and the
Administrative Agent, if applicable, as set forth in Section 11.1 of the
Agreement.

     6.   Several Liability of Banks.  The obligation of each Bank hereunder is
          --------------------------
several, and the failure of one Bank to perform hereunder shall in no way
relieve the other Banks from performance.

     7.   Liability of Administrative Agent.  Administrative Agent shall not be
          ---------------------------------
liable or answerable for anything whatsoever in connection with this Agreement
except for its willful

                                      C-1
                    RELATIONS AMONG THE BANKS AND THE AGENT
<PAGE>

misconduct or gross negligence, and Administrative Agent shall have no duties or
obligations other than as provided herein. Administrative Agent shall be
entitled to rely on any opinion of counsel (including counsel for Borrower) in
relation to this Agreement, and upon statements and communications received from
Borrower, or from any other person, believed by it to be authentic, and shall
not be liable for any action taken or omitted in good faith on such reliance.

     8.   Indemnification of Administrative Agent.  Each Bank agrees to
          ---------------------------------------
indemnify Administrative Agent (to the extent not reimbursed by Borrower and
without limiting the obligation of Borrower to do so), ratably according to its
Normal Percentage, from and against any and all liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against Administrative Agent in any way relating to or arising
out of this Agreement or any action taken or omitted by Administrative Agent
under this Agreement except for Administrative Agent's gross negligence or
willful misconduct.  The obligations of the Banks under this Section 8 shall
survive termination of the Agreement.

     9.   Rights of Administrative Agent as Bank.  With respect to its
          --------------------------------------
obligation to lend under this Agreement and the Loans made by it, Bank of
America shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though it were not Administrative Agent; and the term
"Banks" shall include Bank of America in its individual capacity.  Bank of
America may accept deposits from, lend money to, and generally engage in any
kind of banking, trust or other business with Borrower as if it were not
Administrative Agent.

     10.  Assignment by Bank of its Obligations.  Administrative Agent may deem
          --------------------------------------
and treat a Bank party to this Agreement as the owner of such Bank's portion of
the Loans for all purposes hereof unless and until a written notice of the
assignment or transfer of such Bank's obligations otherwise permitted under the
Agreement executed by such Bank shall have been received by Administrative
Agent, together with Borrower's consent to such assignment or transfer and such
other documentation from such Bank and its assignee or transferee as
Administrative Agent may reasonably request.

     11.  Representations by Banks.  Neither Administrative Agent nor any Bank
          ------------------------
has made or makes to any other Bank any representation, and neither
Administrative Agent nor any Bank assumes any responsibility, in respect to the
execution, construction or enforcement of this Agreement or any other instrument
or agreement executed by Borrower or by any other person or entity.

     12.  Independent Investigation by Banks.  Each Bank has made and shall
          ----------------------------------
continue to make its own independent investigation of the financial condition
and affairs of Borrower in connection with the making and the continuance of the
Loans and has made and covenants that it shall continue to make its own
appraisal of the creditworthiness of Borrower.  Each Bank agrees Administrative
Agent has no duty or responsibility, either initially or on a continuing basis,
to provide any Bank with any credit or other information with respect to
Borrower, whether coming into its possession before the making of the Loans or
at any time or times thereafter except as expressly provided in this Agreement.

                    RELATIONS AMONG THE BANKS AND THE AGENT
<PAGE>

     13.  Successor Administrative Agent.  Administrative Agent shall have the
          ------------------------------
right, at any time, to resign as Administrative Agent for the Banks hereunder.
Such resignation shall not be effective until a successor Administrative Agent
chosen by Majority Banks, and accepted by Borrower, shall accept appointment as
Administrative Agent for the Banks hereunder. If no successor Administrative
Agent shall have been so appointed by the Majority Banks and shall have accepted
such appointment, within 30 days after the retiring Administrative Agent has
given notice of resignation, the retiring Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent reasonably acceptable to
Borrower, which successor Administrative Agent shall be a commercial bank
organized under the laws of the United States of America or a State thereof
having a combined capital and surplus of at least $100,000,000.  Upon the
acceptance by the successor Administrative Agent of its appointment hereunder,
the successor Administrative Agent shall succeed to and become vested with all
the rights and obligations of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its obligations under
this Agreement.  The provisions of this Article shall inure to the benefit of
the retiring Administrative Agent as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement.  After any
retiring Administrative Agent's resignation hereunder as Administrative Agent,
the provisions of this Exhibit C and Section 11.14 shall inure to its benefit as
to any actions taken or omitted to be taken by it while it was Administrative
Agent under this Agreement.

     14.  Syndication Agent; Documentation Agents.  None of the Banks identified
          ---------------------------------------
on the facing page or signature pages of this Agreement as Syndication Agent or
Documentation Agents shall have any right, power, obligation, liability,
responsibility or duty under this Agreement other than those applicable to all
Banks as such.  Without limiting the foregoing, none of the Banks so identified
shall have or be deemed to have any fiduciary relationship with any Bank.  Each
Bank acknowledges that it has not relied, and will not rely, on any of the Banks
so identified in deciding to enter into this Agreement or in taking or not
taking action hereunder.

To:  The Banks listed on Schedule A hereto; Bank
     of America, N.A., as Administrative Agent;

     Deutsche Bank AG, New York Branch, as
     Documentation Agent

     Re:  Hughes Electronics Corporation
          Revolving Credit Agreement
          --------------------------

Ladies and Gentlemen:

     I am the Assistant General Counsel of Hughes Electronics Corporation, a
Delaware corporation (the "Borrower"), in connection with the extension to
Borrower of a revolving line of credit extended under and subject to the terms
and provisions of the Revolving Credit Agreement (364-day Facility) dated as of
November 24, 1999 and made among Hughes Electronics Corporation, the banks
parties thereto ("Banks"), Bank of America, N.A., as administrative agent for
the Banks (in such capacity "Administrative Agent"), Citicorp USA, Inc., as
Syndication Agent and Deutsche Bank AG, New York Branch as Documentation Agent
(the "Agreement").  Capitalized terms not otherwise defined herein shall have
the meanings set forth in the Credit Agreement.  This opinion is rendered to you
pursuant to Section 5.2(b) of the Credit Agreement.

     As Assistant General Counsel to Borrower, I have caused to be made such
legal and factual examinations and inquiries, including an examination of
originals or copies, certified or otherwise identified to my satisfaction as
authentic, of such corporate records, agreements, instruments and other
documents as I have deemed necessary or appropriate for the purposes of this
opinion.  I have caused to be obtained such certificates and other assurances
(copies of which have been delivered to you) from public officials and officers
and other employees of Borrower as I considered necessary or appropriate for the
purpose of rendering this opinion.  I have assumed the genuineness of all
signatures (except that of Borrower), the authenticity of all documents
submitted to me as originals, and the conformity with the originals of all
documents submitted to me as copies.

     Subject to the limitations herein set forth, I am opining herein as to the
effect on the subject transaction only of United States federal law, the laws of
the State of California and the General Corporation Law of the State of
Delaware.  I am licensed to practice law in the State of

                                      F-1
                              OPINION OF COUNSEL
<PAGE>

California. I assume no responsibility as to the applicability to the subject
transaction or the effect thereon of the laws of any other jurisdiction.

     Based upon the foregoing and in reliance thereon, and subject to the
qualifications, limitations and assumptions set forth herein, I am of the
opinion that, as of the date hereof:

     1.   Borrower is a corporation duly incorporated and validity existing as a
corporation in good standing under the laws of the State of Delaware, with full
corporate power and authority to own and lease its properties and conduct its
business as presently owned and conducted.

     2.   Borrower is duly qualified to do business as a foreign corporation in
good standing in the State of California.

     3.   Borrower has full corporate power and authority to borrow the sums
provided for in the Credit Agreement, to execute and deliver the Credit
Agreement and to perform its obligations thereunder.

     4.   All corporate action required to be taken by Borrower for the
authorization, execution and delivery of the Credit Agreement by Borrower and
the performance by Borrower of its obligations thereunder has been duly taken.

     5.   The officer of Borrower executing the Credit Agreement is duly and
properly in office and duly authorized to execute the same.

     6.   The Credit Agreement is a valid and binding agreement of Borrower,
subject to the limitations, qualifications, exceptions and assumptions set forth
below.

     7.   To my knowledge, after causing to be conducted such legal and factual
examination and inquiries and causing to be conducted such discussions with and
obtaining such certificates or other confirmations from officers and other
employees of Borrower as I considered appropriate in the circumstances, no
consent, permission, authorization, order or license of any United States
federal or California governmental authority is necessary in connection with the
execution and delivery of the Credit Agreement by Borrower and Borrower's
performance of its obligations under the Credit Agreement.

     8.   There is no provision of the Certificate of Incorporation or the By-
laws of Borrower which would be contravened by the execution and delivery of the
Credit Agreement by Borrower or by the performance by Borrower of its
obligations under the Credit Agreement.

     9.   Borrower is not an "investment company" as defined in the Investment
Company Act of 1940, as amended.

     10.  To my knowledge, after causing to be conducted such legal and factual
examination and inquiries and causing to be conducted such discussions with and
obtaining such certificates or other confirmations from officers and other
employees of Borrower as I considered appropriate in the circumstances, no
consent or approval of any trustee or holder of any material indebtedness of
Borrower is necessary in connection with the execution and

                                      F-2
                              OPINION OF COUNSEL
<PAGE>

delivery of the Credit Agreement by Borrower and Borrower's performance of its
obligations under the Credit Agreement.

     11.  There is no provision of any indenture or material agreement for
borrowed money to which Borrower is a party or under which Borrower is
obligated, and of which I am aware, after causing to be conducted such legal and
factual examinations and inquiries and causing to be conducted such discussion
with and obtaining such certificates or other confirmations from officers and
other employees of Borrower as I considered appropriate in the circumstances,
which would be contravened by the execution and delivery of the Credit Agreement
and the Notes by Borrower or by the performance by Borrower of its obligations
under the Credit Agreement.

     12.  To my knowledge, after causing to be conducted such legal and factual
examinations and inquiries and causing to be conducted such discussions with and
obtaining such certificates or other confirmations from officers and other
employees of Borrower as I considered appropriate in the circumstances, there is
no judgment, decree or order of any court or governmental agency binding on
Borrower which would be contravened by the execution and delivery of the Credit
Agreement by Borrower and Borrower's performance of its obligations under the
Credit Agreement and the Notes.

     13.  To my knowledge, after causing to be conducted such legal and factual
examinations and inquiries and obtaining certificates or other confirmations
from officers and employees of Borrower as I considered appropriate in the
circumstances, except as set forth in Attachment 1 hereto, there is no claim,
suit, action or proceeding pending or threatened against Borrower before any
court or governmental agency which could reasonably be expected to result in a
Material Adverse Change.

     The opinion expressed in paragraph 6 is subject to the following
limitations, qualifications, exceptions and assumptions:

     (a) the enforcement of the Credit Agreement and the Notes may be limited by
bankruptcy, insolvency, reorganization, moratorium or other similar laws or by
equitable principles relating to or limiting the rights of creditors generally;

     (b) the use of the term enforceable shall not imply any opinion as to the
availability of equitable remedies;

     (c) I advise you that a California court may not strictly enforce certain
covenants contained in the Credit Agreement or allow acceleration of the
maturity of the indebtedness thereunder if it concludes that such enforcement or
acceleration would be unreasonable under the then existing circumstances. I do
believe, however, that subject to the limitations expressed elsewhere in this
opinion, enforcement or acceleration would be available if an Event of Default
occurs as a result of a material breach of a material covenant contained in the
Credit Agreement;

     (d) The effect of California court decisions, invoking statutes or
principles of equity, which have held that certain covenants and provisions of
agreements are unenforceable where (i) the breach of such covenants or
provisions imposes restrictions or burdens upon the debtor,

                                      F-3
                              OPINION OF COUNSEL
<PAGE>

including the acceleration of indebtedness due under debt instruments, and it
cannot be demonstrated that the enforcement of such restrictions or burdens is
reasonably necessary for the protection of the creditor, or (ii) the creditor's
enforcement of such covenants or provisions under the circumstances would
violate the creditor's implied covenant of good faith and fair dealing;

     (e) The unenforceability under certain circumstances, under California or
federal law or court decisions, of provisions expressly or by implication
waiving broadly or vaguely stated rights, unknown future rights, defenses to
obligations or rights granted by law, where such waivers are against public
policy or prohibited by law;

     (f) The unenforceability under certain circumstances of provisions to the
effect that rights or remedies are not exclusive, that every right or remedy is
cumulative and may be exercised in addition to or with any other right or
remedy, that election of a particular remedy or remedies does not preclude
recourse to one or more other remedies or that failure to exercise or delay in
exercising rights or remedies will not operate as a waiver of any such right or
remedy;

     (g) The effect of Section 1717 of the California Civil Code, which provides
that, where a contract permits one party to the contract to recover attorneys'
fees, the prevailing party in any action to enforce any provision of the
contract shall be entitled to recover its reasonable attorneys' fees;

     (h) The unenforceability under certain circumstances of provisions
indemnifying a party against liability for its own wrongful or negligent acts or
where such indemnification is contrary to public policy or prohibited by law;
and

     (i) The enforceability under certain circumstances of provisions imposing
penalties, forfeitures, late payment charges or an increase in interest rate
upon delinquency in payment or the occurrence of a default.

     To the extent that the obligations of Borrower may be dependent upon such
matters, I assume for purposes of this opinion that each of the Banks is duly
incorporated or organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation or organization; that each of the Banks is
duly qualified to engage in the transaction covered by this opinion; that the
Credit Agreement has been duly authorized, executed and delivered by each of the
Banks and that the Credit Agreement constitutes the valid and binding obligation
of each of the Banks, enforceable in accordance with its terms; and that each of
the Banks has the requisite corporate or organizational and legal power and
authority to own its properties, to carry on its business as now being conducted
and to perform its obligations under the Credit Agreement, including without
limitation, to make the loans under the Credit Agreement.  I am not expressing
any opinion as to the effect of or the compliance by any Bank with any state or
federal laws or regulations applicable to the transactions because of the nature
of its respective business.

     This opinion is rendered to the Banks and Administrative Agent as of the
date hereof in connection with the above transaction, and may not be relied upon
by any person other than the Administrative Agent and the Banks and their
permitted assignees, or by them in any other

                                      F-4

context, and may not be furnished to, quoted to or relied upon by any other
person, firm or corporation for any purpose without my prior written consent;
provided that each Bank and its permitted assignees may provide this opinion
--------
(i) to bank examiners and other regulatory authorities should they so request or
in connection with their normal examination, (ii) to the independent auditors
and attorneys of such Bank, (iii) pursuant to order or legal process of any
court or governmental agency, (iv) in connection with any legal action to which
the Bank is a party arising out of the transactions contemplated by the Credit
Agreement, or (v) in connection with the assignment of or sale of participations
in the Loans.
