Amount of all L/C Obligations shall not at any time exceed such Bank's
Commitment.  Within the limits of each Bank's Commitment, and subject to the
other terms and conditions hereof, the Company may borrow under this Section
2.01, prepay under Section 2.06 and reborrow under this Section 2.01.

or records maintained by such Bank or Issuing Bank, as the case may be, in the
ordinary course of business.  The accounts or records maintained by the Agent,
the Issuing Bank and each Bank shall be conclusive absent manifest error of the
amount of the Loans made by the Banks to the Company and the Letters of Credit
Issued for the account of the Company, and the interest and payments thereon.
Any failure so to record or any error in doing so shall not, however, limit or
otherwise affect the obligation of the Company hereunder to pay any amount owing
with respect to the Loans or any Letter of Credit.

          (b) Upon the request of any Bank made through the Agent, the Loans
made by such Bank may be evidenced by one or more Notes, instead of or in
addition to loan accounts.  Each such Bank shall endorse on the schedules
annexed to its Note(s) the date, amount and maturity of each Loan made by it and
the amount of each payment of principal made by the Company with respect
thereto.  Each such Bank is irrevocably authorized by the Company to endorse its
Note(s) and each Bank's record shall be conclusive absent manifest error;

the obligations of the Company hereunder or under any such Note to such Bank.

          Interest Period shall be one (1) month;

provided, however, that with respect to the Borrowing to be made on the Closing
--------  -------

     of any other Type of Revolving Loans, to convert any such Loans (or any
     part thereof in an amount not less than $5,000,000, or that is in an
     integral multiple of $1,000,000 in excess thereof) into Loans of any other
     Type; or

               (ii)  elect as of the last day of the applicable Interest Period,
     to continue any Offshore Rate Loans (or any part thereof in an amount not
     less than $5,000,000, or that is in an integral multiple of $1,000,000 in
     excess thereof) with Interest Periods identical to the then expiring
     Offshore Rate Loan or with different Interest Periods as specified in the
     Notice of Conversion/Continuation.

provided, that if at any time the aggregate amount of Offshore Rate Loans in
--------                                                                    
respect of any Borrowing is reduced, by payment, prepayment, or conversion of
part thereof to be less than $5,000,000, such Offshore Rate Loans shall
automatically convert into Base Rate Loans, and on and after such date the right
of the Company to continue such Loans as Offshore Rate Loans shall terminate.

          (b) The Company shall deliver a Notice of Conversion/Continuation to
be received by the Agent (i) not later than 10:00 a.m. (San Francisco time) at
least three Business Days in advance of the Conversion/Continuation Date, if the

if the Loans are to be converted into Base Rate Loans, specifying:

                    (A)  the proposed Conversion/Continuation Date;

                    (B)  the aggregate amount of Loans to be converted or
          continued;

                    (C)  the Type of Loans resulting from the proposed

          Loans, the duration of the requested Interest Period.

          (c) If upon the expiration of any Interest Period applicable to
Offshore Rate Loans, the Company has failed to select timely a new Interest
Period to be applicable to such Offshore Rate Loans, or if any Default or Event
of Default then exists, the Company shall be deemed to have elected to convert
such Offshore Rate Loans into Base Rate Loans effective as of the expiration
date of such Interest Period.

          (d) The Agent will promptly notify each Bank of its receipt of a
Notice of Conversion/Continuations, or, if no timely notice is provided by the
Company, the Agent will promptly notify each Bank of the details of any
automatic conversion.  All conversions and continuations shall be made ratably
according to the 

                                      -33-

respective outstanding principal amounts of the Loans with respect to which the
notice was given held by each Bank.

          (e) Unless the Required Banks otherwise consent, during the existence
of a Default or Event of Default, the Company may not elect to have a Loan
converted into or continued as an Offshore Rate Loan.

          (f) After giving effect to any conversion or continuation of Loans,
unless the Agent shall otherwise consent, there may not be more than five (5)

      2.05     Voluntary Termination or Reduction of Commitments.  Subject to
               -------------------------------------------------             
Section 4.04, the Company may, upon not less than three (3) Business Days' prior
notice to the Agent (and upon receipt of such notice the Agent shall promptly
notify the Banks thereof), terminate the Commitments, or permanently reduce the
Commitments by an aggregate minimum amount of $5,000,000 or any multiple of
$1,000,000 in excess thereof; unless, after giving effect thereto and to any
                              ------                                        
prepayments of Loans made on the effective date thereof, (a) the Effective
Amount of all Revolving Loans and L/C Obligations together would exceed the
amount of the Combined Commitments then in effect, or (b) the Effective Amount
of all L/C Obligations then outstanding would exceed the L/C Commitment.  Once
reduced in accordance with this Section, the Commitments may not be increased.
Any reduction of the Commitments shall be applied to each Bank according to its
Pro Rata Share.  If and to the extent specified by the Company in the notice to
the Agent, some or all of the reduction in the Combined Commitments shall be
applied to reduce the L/C Commitment.  All accrued commitment and letter of
credit fees to, but not including, the effective date of any reduction or
termination of Commitments, shall be paid on the effective date of such
reduction or termination.

      2.06     Optional Prepayments. Subject to Section 4.04, the Company may,
               --------------------                                           
at any time or from time to time, upon not less than three (3) Business Days'
irrevocable notice to the Agent with respect to Offshore Rate Loans and upon not
less than one (1) Business Days' irrevocable notice to the Agent with respect to
Base Rate Loans, ratably prepay Loans in whole or in part, in minimum amounts of
$5,000,000 or any multiple of $1,000,000 in excess thereof.  Such notice of
prepayment shall specify the date (which shall be a Business Day) and amount of
such prepayment and the Type(s) of Loans to be prepaid.  The Agent will promptly
notify each Bank of its receipt of any such notice, and of such Bank's Pro Rata
Share of such prepayment.  If such notice is given by the Company, the Company
shall make such prepayment and the payment amount specified in such notice shall
be due and payable on the date specified therein, together with accrued interest
to each such date on the amount prepaid and any amounts required pursuant to
Section 4.04.

      2.07     Mandatory Commitment Reductions; Mandatory Prepayments of Loans.
               --------------------------------------------------------------- 

          (a) The Combined Commitments shall be automatically and permanently
reduced on each reduction date set forth below by the amount set forth opposite
such date as follows:

<TABLE>
<CAPTION>
     Reduction Date        Reduction Amount
     --------------        ----------------
     <S>                   <C>

     December 31, 1999     $40,000,000
     December 31, 2000     $80,000,000
     December 31, 2001     $80,000,000
     Revolving Termination Date  Balance of Combined Commitments
</TABLE>

In the event that on any date the Combined Commitments are reduced pursuant to
clause (a) or (b) of this Section 2.07, the Effective Amount of all outstanding
Revolving Loans, and the Effective Amount of all L/C Obligations, exceeds the
Combined Commitments in effect on such date after giving effect to such
reduction, the Company shall, on such date, make a mandatory prepayment of the
Loans in a principal amount equal to such excess, so that after giving effect to
such prepayment, the Effective Amount of all outstanding Revolving Loans, and
the Effective Amount of all L/C Obligations, shall not exceed the Combined
Commitments as of such date and the Effective Amount of the Revolving Loans of
any Bank plus the participation of such Bank in the Effective Amount of all L/C
Obligations shall not exceed such Bank's Commitment as of such date.

          (b)  (i) Upon consummation of any Excess Subordinated Debt Issuance, a
portion of the Combined Commitments equal to the amount of Net Proceeds of such
Excess Subordinated Debt Issuance shall be permanently reduced by an amount
equal to the sum of such Net Proceeds.

               (ii) Upon consummation of any Asset Sale (as such term is defined
     in the Indenture) which results in any amounts becoming due and owing under
     the Subordinated Note Documents, a portion of the Combined Commitments
     equal to the amount of Net Cash Proceeds (as such term is defined in the
     Indenture) resulting from such Asset Sale shall be permanently reduced by
     an amount equal to the sum of such Net Cash Proceeds resulting from such
     Asset Sale.

          (c) If on any date the Effective Amount of L/C Obligations exceeds the
L/C Commitment, the Company shall Cash Collateralize on such date the
outstanding Letters of Credit in an amount equal to the excess of the maximum
amount then available to be drawn under the Letters of Credit over the Aggregate
L/C Commitment.  Subject to Section 4.04, if on any date after giving effect to
any Cash Collateralization made on such date pursuant to the preceding sentence,
the Effective Amount of all Revolving Loans then outstanding plus the Effective
Amount of all L/C Obligations exceeds the Combined Commitments, the Company
shall immediately, and without notice or demand, prepay the outstanding
principal amount of the Revolving Loans and L/C Advances by an amount equal to
the applicable excess.

                                      -35-
<PAGE>
 
          (d) Each reduction in the Combined Commitments hereunder shall be made
ratably among the Banks in accordance with their respective Commitments.  The
Company shall pay to the Agent for the account of the Banks on the date of each
termination or reduction in the Combined Commitments, the commitment fees on the
amount of the Combined Commitments so terminated or reduced accrued to the date
of such termination or reduction.

          (e) On any date when the outstanding Loans (after giving effect to any
Borrowings effected on such date) exceeds the Combined Commitments, the Company
shall make a mandatory prepayment of the Loans in such amount as may be
necessary so that the aggregate amount of outstanding Loans after giving effect
to such prepayment does not exceed the Combined Commitments then in effect.

          (f) Simultaneously with each prepayment of a Loan, the Company shall
prepay all accrued interest on the amount prepaid through the date of
prepayment.  Unless otherwise specified by the Company, each prepayment of
Revolving Credit Loans shall first be applied to Base Rate Loans.  If any
prepayment is made in respect of any of Offshore Rate Loans, in whole or in
part, prior to the last day of the applicable Interest Period, the Company
agrees to indemnify the Banks in accordance with Section 4.04.

     2.08 Repayment.  The Company shall repay to the Banks on the Revolving
          ---------                                                        
Termination Date the aggregate principal amount of Revolving Loans, and subject
to Section 3.01 hereof, the aggregate principal amount of L/C Advances, each
outstanding on such date.

      2.09     Interest.  (a) Each Revolving Loan shall bear interest on the
               --------                                                     
outstanding principal amount thereof from the applicable Borrowing Date at a
rate per annum equal to the Offshore Rate or the Base Rate, as the case may be
(and subject to the Company's right to convert to other Types of Loans under
Section 2.04), plus the Applicable Margin.
               ----                       

          (b) Interest on each Revolving Loan shall be paid in arrears on each
Interest Payment Date.  Interest shall also be paid on the date of any
prepayment of Loans under Section 2.06 or 2.07 for the portion of the Loans so
prepaid and upon payment (including prepayment) in full thereof and, during the
existence of any Event of Default, interest shall be paid on demand of the Agent
at the request or with the consent of the Required Banks.

          (c) Notwithstanding clause (a) of this Section 2.09, while any Event
of Default exists or after acceleration of any of the Obligations hereunder, the
Company shall pay interest (after as well as before entry of judgment thereon to
the extent permitted by law) on the principal amount of all outstanding Loans,
at a rate per annum which is determined by adding 2% per annum to the Applicable
Margin then in effect for such Loans and, in the case of Obligations not subject
to an Applicable Margin, at a rate per annum which is determined by adding 2%
per annum to the Base Rate; provided, however, that, on and after the expiration
                            --------  -------                                   
of any Interest Period applicable to any Offshore Rate Loan outstanding on the
date of occurrence of such Event of Default or 

                                      -36-
<PAGE>
 
acceleration, the principal amount of such Loan shall, during the continuation
of such Event of Default or after acceleration, bear interest at a rate per
annum which is determined by adding 2% per annum to the Base Rate.

          (d) Anything herein to the contrary notwithstanding, the obligations
of the Company to any Bank hereunder shall be subject to the limitation that
payments of interest shall not be required for any period for which interest is
computed hereunder, to the extent (but only to the extent) that contracting for
or receiving such payment by such Bank would be contrary to the provisions of
any law applicable to such Bank limiting the highest rate of interest that may
be lawfully contracted for, charged or received by such Bank, and in such event
the Company shall pay such Bank interest at the highest rate permitted by
applicable law.

      2.10     Fees.  In addition to certain fees described in Section 3.08:
               ----                                                         

          (a) Arrangement, Agency Fees.  The Company shall pay an arrangement
              ------------------------                                       
fees to the Arranger for the Arranger's own account, and shall pay agency fees
to the Agent for the Agent's own account, as required by the letter agreement
("Fee Letter") among the Company, the Arranger and Agent dated April 2, 1998.
  ----------                                                                 

          (b) Commitment Fees.  The Company shall pay to the Agent for the
              ---------------                                             
account of each Bank a commitment fee on the average daily unused portion of
such Bank's Commitment, computed on a quarterly basis in arrears on the last
Business Day of each calendar quarter based upon the daily utilization for that
quarter as calculated by the Agent, equal to the Applicable Commitment Fee Rate.
For purposes of calculating utilization under this Section, the Commitments
shall be deemed used to the extent of the Effective Amount of Revolving Loans
then outstanding, plus the Effective Amount of L/C Obligations then outstanding.
Such commitment fee shall accrue from the Closing Date to the Revolving
Termination Date and shall be due and payable quarterly in arrears on the last
Business Day of each calendar year quarter commencing on June 30, 1998 through
the Revolving Termination Date, with the final payment to be made on the
Revolving Termination Date; provided that, in connection with any reduction or
                            --------                                          
termination of Commitments under Section 2.05 or Section 2.07, the accrued
commitment fee calculated for the period ending on such date shall also be paid
on the date of such reduction or termination, with the following quarterly
payment being calculated on the basis of the period from such reduction or
termination date to such quarterly payment date.  The commitment fees provided
in this Section shall accrue at all times after the above-mentioned commencement
date, including at any time during which one or more conditions in Article V are
not met.

      2.11     Computation of Fees and Interest.  (a) All computations of
               --------------------------------                          
interest for Base Rate Loans when the Base Rate is determined by BofA's
"reference rate" shall be made on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed. All other computations of fees and
interest shall be made on the basis of a 360-day year and actual days elapsed
(which results in more interest being paid than if computed on the basis of a
365-day year).  Interest and fees shall accrue during each 

                                      -37-
<PAGE>
 
period during which interest or such fees are computed from the first day
thereof to the last day thereof.

          (b) Each determination of an interest rate and any fees referenced in
Section 2.10 by the Agent shall be conclusive and binding on the Company and the
Banks in the absence of manifest error.  The Agent will, at the request of the
Company or any Bank, deliver to the Company or the Bank, as the case may be, a
statement showing the quotations used by the Agent in determining any interest
rate and the resulting interest rate.

      2.12     Payments by the Company.  (a) All payments to be made by the
               -----------------------                                     
Company shall be made without set-off, recoupment or counterclaim.  Except as
otherwise expressly provided herein, all payments by the Company shall be made
to the Agent for the account of the Banks at the Agent's Payment Office, and
shall be made in dollars and in immediately available funds, no later than 11:00
A.M. (San Francisco time) on the date specified herein.  The Agent will promptly
distribute to each Bank its Pro Rata Share (or other applicable share as
expressly provided herein) of such payment in like funds as received.  Any
payment received by the Agent later than 11:00 A.M. (San Francisco time) shall
be deemed to have been received on the following Business Day and any applicable
interest or fee shall continue to accrue.

          (b) Subject to the provisions set forth in the definition of "Interest
Period" herein, whenever any payment is due on a day other than a Business Day,
such payment shall be made on the following Business Day, and such extension of
time shall in such case be included in the computation of interest or fees, as
the case may be.

          (c) Unless the Agent receives notice from the Company prior to the
date on which any payment is due to the Banks that the Company will not make
such payment in full as and when required, the Agent may assume that the Company
has made such payment in full to the Agent on such date in immediately available
funds and the Agent may (but shall not be so required), in reliance upon such
assumption, distribute to each Bank on such due date an amount equal to the
amount then due such Bank.  If and to the extent the Company has not made such
payment in full to the Agent, each Bank shall repay to the Agent on demand such
amount distributed to such Bank, together with interest thereon at the Federal
Funds Rate for each day from the date such amount is distributed to such Bank
until the date repaid.

      2.13     Payments by the Banks to the Agent.  (a) Unless the Agent
               ----------------------------------                       
receives notice from a Bank on or prior to the Closing Date or, with respect to
any Borrowing after the Closing Date, at least one Business Day prior to the
date of such Borrowing, that such Bank will not make available as and when
required hereunder to the Agent for the account of the Company the amount of
that Bank's Pro Rata Share of the Borrowing, the Agent may assume that each Bank
has made such amount available to the Agent in immediately available funds on
the Borrowing Date and the Agent may (but shall not be so required), in reliance
upon such assumption, make available to the Company on such date a corresponding
amount.  If and to the extent any Bank shall not have made its full amount
available to the Agent in immediately available funds as and when required and

                                      -38-
<PAGE>
 
the Agent in such circumstances has made available to the Company such amount,
that Bank shall on the Business Day following such Borrowing Date make such
amount available to the Agent, together with interest at the Federal Funds Rate
for each day during such period. A notice of the Agent submitted to any Bank
with respect to amounts owing under this Section (a) shall be conclusive, absent
manifest error.  If such amount is so made available, such payment to the Agent
shall constitute such Bank's Loan on the date of Borrowing for all purposes of
this Agreement.  If such amount is not made available to the Agent on the
Business Day following the Borrowing Date, the Agent will notify the Company of
such failure to fund and, upon demand by the Agent, the Company shall pay such
amount to the Agent for the Agent's account, together with interest thereon for
each day elapsed since the date of such Borrowing, at a rate per annum equal to
the interest rate applicable at the time to the Loans comprising such Borrowing.

          (b) The failure of any Bank to make any Loan on any Borrowing Date
shall not relieve any other Bank of any obligation hereunder to make a Loan on
such Borrowing Date, but no Bank shall be responsible for the failure of any
other Bank to make the Loan to be made by such other Bank on any Borrowing Date.

      2.14     Sharing of Payments, Etc.  If, other than as expressly provided
               -------------------------                                      
elsewhere herein, any Bank shall obtain on account of the Obligations in its
favor any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) in excess of its ratable share (or other share
contemplated hereunder), such Bank shall immediately (a) notify the Agent of
such fact, and (b) purchase from the other Banks such participations in the
Loans made by them as shall be necessary to cause such purchasing Bank to share
the excess payment pro rata with each of them; provided, however, that if all or
                                               --------  -------                
any portion of such excess payment is thereafter recovered from the purchasing
Bank, such purchase shall to that extent be rescinded and each other Bank shall
repay to the purchasing Bank the purchase price paid therefor, together with an
amount equal to such paying Bank's ratable share (according to the proportion of
(i) the amount of such paying Bank's required repayment to (ii) the total amount
so recovered from the purchasing Bank) of any interest or other amount paid or
payable by the purchasing Bank in respect of the total amount so recovered.  The
Company agrees that any Bank so purchasing a participation from another Bank
may, to the fullest extent permitted by law, exercise all its rights of payment
(including the right of set-off, but subject to Section 11.10) with respect to
such participation as fully as if such Bank were the direct creditor of the
Company in the amount of such participation.  The Agent will keep records (which
shall be conclusive and binding in the absence of manifest error) of
participations purchased under this Section and will in each case notify the
Banks following any such purchases or repayments.

                             THE LETTERS OF CREDIT
                             ---------------------

      3.01     The Letter of Credit Subfacility.  (a) On the terms and
               --------------------------------                       
conditions set forth herein (i) the Issuing Bank agrees, (A) from time to time
on any Business Day during the period from the Closing Date to the Revolving
Termination Date to issue Letters of Credit for the account of the Company, and
to amend or renew Letters of Credit previously issued by it, in accordance with
Sections 3.02(c) and 3.02(d), and (B) to honor drafts under the Letters of
Credit; and (ii) the Banks severally agree to participate in Letters of Credit
Issued for the account of the Company; provided, that the Issuing Bank shall not
                                       --------                                 
be obligated to Issue, and no Bank shall be obligated to participate in, any
Letter of Credit if upon the Issuance of such Letter of Credit (the "Issuance
                                                                     --------
Date") or the date of any renewal thereof (1) the Effective Amount of all L/C
----                                                                         
Obligations plus the Effective Amount of all Revolving Loans would exceed the
Combined Commitments, (2) the participation of any Bank in the Effective Amount
of all L/C Obligations plus the Effective Amount of the Revolving Loans of such
Bank would exceed such Bank's Commitment, or (3) the Effective Amount of L/C
Obligations would exceed the L/C Commitment.  Within the foregoing limits, and
subject to the other terms and conditions hereof, the Company's ability to
obtain Letters of Credit shall be fully revolving, and, accordingly, the Company
may, during the foregoing period, obtain Letters of Credit to replace Letters of
Credit which have expired or which have been drawn upon and reimbursed.

          (b) The Issuing Bank is under no obligation to Issue any Letter of
Credit if:

               (i)  any order, judgment or decree of any Governmental Authority
     or arbitrator shall by its terms purport to enjoin or restrain the Issuing
     Bank from Issuing such Letter of Credit, or any Requirement of Law
     applicable to the Issuing Bank or any request or directive (whether or not
     having the force of law) from any Governmental Authority with jurisdiction
     over the Issuing Bank shall prohibit, or request that the Issuing Bank
     refrain from, the Issuance of letters of credit generally or such Letter of
     Credit in particular or shall impose upon the Issuing Bank with respect to
     such Letter of Credit any restriction, reserve or capital requirement (for
     which the Issuing Bank is not otherwise compensated hereunder) not in
     effect on the Closing Date, or shall impose upon the Issuing Bank any
     unreimbursed loss, cost or expense which was not applicable on the Closing
     Date and which the Issuing Bank in good faith deems material to it;

               (ii)  the Issuing Bank has received written notice from any Bank,
     the Agent or the Company, on or prior to the Business Day prior to the
     requested date of Issuance of such Letter of Credit, that one or more of
     the applicable conditions contained in Article V is not then satisfied;

               (iii)  the expiry date of any requested Letter of Credit is (A)
     more than 360 days after the date of Issuance, in the case of any
     commercial Letter of 

                                      -40-
<PAGE>
 
     Credit, or more than 365 or 366 days after the date of Issuance, in the
     case of any standby Letter of Credit, unless, in either case, the Required
     Banks have approved such expiry date in writing, or (B) after the Revolving
     Termination Date, unless all of the Banks have approved such expiry date in
     writing;

               (iv)  the expiry date of any requested Letter of Credit is prior
     to the maturity date of any financial obligation to be supported by the
     requested Letter of Credit;

               (v)  any requested Letter of Credit does not provide for drafts,
     or is not otherwise in form and substance acceptable to the Issuing Bank,
     or the Issuance of a Letter of Credit shall violate any applicable policies
     of the Issuing Bank;

               (vi)  any standby Letter of Credit is for the purpose of
     supporting the issuance of any letter of credit by any other Person; or

               (vii)  such Letter of Credit is in a face amount less than
     $250,000 or denominated in a currency other than Dollars.

      3.02     Issuance, Amendment and Renewal of Letters of Credit.  (a) Each
               ----------------------------------------------------           
Letter of Credit shall be issued upon the irrevocable written request of the
Company received by the Issuing Bank (with a copy sent by the Company to the
Agent) at least four days (or such shorter time as the Issuing Bank may agree in
a particular instance in its sole discretion) prior to the proposed date of
issuance.  Each such request for issuance of a Letter of Credit shall be by
facsimile, confirmed immediately in an original writing, in the form of an L/C
Application, and shall specify in form and detail satisfactory to the Issuing
Bank: (i) the proposed date of issuance of the Letter of Credit (which shall be
a Business Day); (ii) the face amount of the Letter of Credit; (iii) the expiry
date of the Letter of Credit; (iv) the name and address of the beneficiary
thereof; (v) the documents to be presented by the beneficiary of the Letter of
Credit in case of any drawing thereunder; (vi) the full text of any certificate
to be presented by the beneficiary in case of any drawing thereunder; and (vii)
such other matters as the Issuing Bank may require.

          (b) At least two Business Days prior to the Issuance of any Letter of
Credit, the Issuing Bank will confirm with the Agent (by telephone or in
writing) that the Agent has received a copy of the L/C Application or L/C
Amendment Application from the Company and, if not, the Issuing Bank will
provide the Agent with a copy thereof. Unless the Issuing Bank has received
notice on or before the Business Day immediately preceding the date the Issuing
Bank is to issue a requested Letter of Credit from the Agent (A) directing the
Issuing Bank not to issue such Letter of Credit because such issuance is not
then permitted under Section 3.01(a) as a result of the limitations set forth in
clauses (1) through (3) thereof or Section 3.01(b)(ii); or (B) that one or more
conditions specified in Article V are not then satisfied; then, subject to the
terms and conditions hereof, the Issuing Bank shall, on the requested date,
issue a Letter of Credit for the account of the Company in accordance with the
Issuing Bank's usual and customary business practices.

                                      -41-
<PAGE>
 
          (c) From time to time while a Letter of Credit is outstanding and
prior to the Revolving Termination Date, the Issuing Bank will, upon the written
request of the Company received by the Issuing Bank (with a copy sent by the
Company to the Agent) at least five days (or such shorter time as the Issuing
Bank may agree in a particular instance in its sole discretion) prior to the
proposed date of amendment, amend any Letter of Credit issued by it.  Each such
request for amendment of a Letter of Credit shall be made by facsimile,
confirmed immediately in an original writing, made in the form of an L/C
Amendment Application and shall specify in form and detail satisfactory to the
Issuing Bank:  (i) the Letter of Credit to be amended; (ii) the proposed date of
amendment of the Letter of Credit (which shall be a Business Day); (iii) the
nature of the proposed amendment; and (iv) such other matters as the Issuing
Bank may require.  The Issuing Bank shall be under no obligation to amend any
Letter of Credit if:  (A) the Issuing Bank would have no obligation at such time
to issue such Letter of Credit in its amended form under the terms of this
Agreement; or (B) the beneficiary of any such letter of Credit does not accept
the proposed amendment to the Letter of Credit.  The Agent will promptly notify
the Banks of the receipt by it of any L/C Application or L/C Amendment
Application.

          (d) The Issuing Bank and the Banks agree that, while a Letter of
Credit is outstanding and prior to the Revolving Termination Date, at the option
of the Company and upon the written request of the Company received by the
Issuing Bank (with a copy sent by the Company to the Agent) at least five days
(or such shorter time as the Issuing Bank may agree in a particular instance in
its sole discretion) prior to the proposed date of notification of renewal, the
Issuing Bank shall be entitled to authorize the renewal of any Letter of Credit
issued by it.  Each such request for renewal of a Letter of Credit shall be made
by facsimile, confirmed immediately in an original writing, in the form of an
L/C Amendment Application, and shall specify in form and detail satisfactory to
the Issuing Bank: (i) the Letter of Credit to be renewed; (ii) the proposed date
of notification of renewal of the Letter of Credit (which shall be a Business
Day); (iii) the revised expiry date of the Letter of Credit; and (iv) such other
matters as the Issuing Bank may require. The Issuing Bank shall be under no
obligation so to renew any Letter of Credit if: (A) the Issuing Bank would have
no obligation at such time to issue or amend such Letter of Credit in its
renewed form under the terms of this Agreement; or (B) the beneficiary of any
such Letter of Credit does not accept the proposed renewal of the Letter of
Credit.  If any outstanding Letter of Credit shall provide that it shall be
automatically renewed unless the beneficiary thereof receives notice from the
Issuing Bank that such Letter of Credit shall not be renewed, and if at the time
of renewal the Issuing Bank would be entitled to authorize the automatic renewal
of such Letter of Credit in accordance with this Section 3.02(d) upon the
request of the Company but the Issuing Bank shall not have received any L/C
Amendment Application from the Company with respect to such renewal or other
written direction by the Company with respect thereto, the Issuing Bank shall
nonetheless be permitted to allow such Letter of Credit to renew, and the
Company and the Banks hereby authorize such renewal, and, accordingly, the
Issuing Bank shall be deemed to have received an L/C Amendment Application from
the Company requesting such renewal.

                                      -42-
<PAGE>
 
          (e) The Issuing Bank may, at its election (or as required by the Agent
at the direction of the Required Banks), deliver any notices of termination or
other communications to any Letter of Credit beneficiary or transferee, and take
any other action as necessary or appropriate, at any time and from time to time,
in order to cause the expiry date of such Letter of Credit to be a date not
later than the Revolving Termination Date.

          (f) This Agreement shall control in the event of any conflict with any
L/C-Related Document (other than any Letter of Credit).

          (g) The Issuing Bank will also deliver to the Agent, concurrently or
promptly following its delivery of a Letter of Credit, or amendment to or
renewal of a Letter of Credit, to an advising bank or a beneficiary, a true and
complete copy of each such Letter of Credit or amendment to or renewal of a
Letter of Credit.

      3.03     Risk Participations, Drawings and Reimbursements.
               ------------------------------------------------ 

          (a) Immediately upon the Issuance of each Letter of Credit, each Bank
shall be deemed to, and hereby irrevocably and unconditionally agrees to,
purchase from the Issuing Bank a participation in such Letter of Credit and each
drawing thereunder in an amount equal to the product of (i) the Pro Rata Share
of such Bank, times (ii) the maximum amount available to be drawn under such
Letter of Credit and the amount of such drawing, respectively.  For purposes of
Section 2.01, each Issuance of a Letter of Credit shall be deemed to utilize the
Commitment of each Bank by an amount equal to the amount of such participation.

          (b) In the event of any request for a drawing under a Letter of Credit
by the beneficiary or transferee thereof, the Issuing Bank will promptly notify
the Company.  The Company shall reimburse the Issuing Bank prior to 11:00 a.m.
(San Francisco time) on each date that any amount is paid by the Issuing Bank
under any Letter of Credit (each such date, an "Honor Date"), in an amount equal
                                                ----------                      
to the amount so paid by the Issuing Bank.  In the event the Company fails to
reimburse the Issuing Bank for the full amount of any drawing under any Letter
of Credit by 11:00 a.m. (San Francisco time) on the Honor Date, the Issuing Bank
will promptly notify the Agent and the Agent will promptly notify each Bank
thereof, and the Company shall be deemed to have requested that Base Rate Loans
be made by the Banks to be disbursed on the Honor Date under such Letter of
Credit, subject to the amount of the unutilized portion of the Revolving
Commitment and subject to the conditions set forth in Section 5.02.  Any notice
given by the Issuing Bank or the Agent pursuant to this Section 3.03(b) may be
oral if immediately confirmed in writing (including by facsimile); provided that
                                                                   --------     
the lack of such an immediate confirmation shall not affect the conclusiveness
or binding effect of such notice.

          (c) Each Bank shall upon any notice pursuant to Section 3.03(b) make
available to the Agent for the account of the relevant Issuing Bank an amount in
Dollars and in immediately available funds equal to its Pro Rata Share of the
amount of the drawing, whereupon the participating Banks shall (subject to
Section 3.03(d)) each be 

                                      -43-
<PAGE>
 
deemed to have made a Revolving Loan consisting of a Base Rate Loan to the
Company in that amount. If any Bank so notified fails to make available to the
Agent for the account of the Issuing Bank the amount of such Bank's Pro Rata
Share of the amount of the drawing by no later than 12:00 noon (San Francisco
time) on the Honor Date, then interest shall accrue on such Bank's obligation to
make such payment, from the Honor Date to the date such Bank makes such payment,
at a rate per annum equal to the Federal Funds Rate in effect from time to time
during such period. The Agent will promptly give notice of the occurrence of the
Honor Date, but failure of the Agent to give any such notice on the Honor Date
or in sufficient time to enable any Bank to effect such payment on such date
shall not relieve such Bank from its obligations under this Section 3.03.

          (d) With respect to any unreimbursed drawing that is not converted
into Revolving Loans consisting of Base Rate Loans to the Company in whole or in
part, because of the Company's failure to satisfy the conditions set forth in
Section 5.02 or for any other reason, the Company shall be deemed to have
incurred from the Issuing Bank an L/C Borrowing in the amount of such drawing,
which L/C Borrowing shall be due and payable on demand (together with interest)
and shall bear interest at a rate per annum determined by adding 2% per annum to
the Applicable Margin assuming such L/C Borrowing were a Base Rate Loan plus the
Base Rate, and each Bank's payment to the Issuing Bank pursuant to Section
3.03(c) shall be deemed payment in respect of its participation in such L/C
Borrowing and shall constitute an L/C Advance from such Bank in satisfaction of
its participation obligation under this Section 3.03.

          (e) Each Bank's obligation in accordance with this Agreement to make
the Revolving Loans or L/C Advances, as contemplated by Sections 3.03(c) and
(d), as a result of a drawing under a Letter of Credit, shall be absolute and
unconditional and without recourse to the Issuing Bank and shall not be affected
by any circumstance, including (i) any set-off, counterclaim, recoupment,
defense or other right which such Bank may have against the Issuing Bank, the
Company or any other Person for any reason whatsoever; (ii) the occurrence or
continuance of a Default, an Event of Default or a Material Adverse Effect; or
(iii) any other circumstance, happening or event whatsoever, whether or not
similar to any of the foregoing; provided, however, that each Bank's obligation
                                 --------                                      
to make Revolving Loans under Section 3.03(c) is subject to the conditions set
forth in Section 5.02.

      3.04     Repayment of Participations.  (a) Upon (and only upon) receipt by
               ---------------------------                                      
the Agent for the account of the Issuing Bank of immediately available funds
from the Company (i) in reimbursement of any payment made by the Issuing Bank
under the Letter of Credit with respect to which any Bank has paid the Agent for
the account of the Issuing Bank for such Bank's participation in the Letter of
Credit pursuant to Section 3.03 or (ii) in payment of interest thereon, the
Agent will pay to each Bank, in the same funds as those received by the Agent
for the account of the Issuing Bank, the amount of such Bank's Pro Rata Share of
such funds, and the Issuing Bank shall receive the amount of the Pro Rata Share
of such funds of any Bank that did not so pay the Agent for the account of the
Issuing Bank.

                                      -44-
<PAGE>
 
          (b) If the Agent or the Issuing Bank is required at any time to return
to the Company, or to a trustee, receiver, liquidator, custodian, or any
official in any Insolvency Proceeding, any portion of the payments made by the
Company to the Agent for the account of the Issuing Bank pursuant to Section
3.04(a) in reimbursement of a payment made under the Letter of Credit or
interest or fee thereon, each Bank shall, on demand of the Agent, forthwith
return to the Agent or the Issuing Bank the amount of its Pro Rata Share of any
amounts so returned by the Agent or the Issuing Bank plus interest thereon from
the date such demand is made to the date such amounts are returned by such Bank
to the Agent or the Issuing Bank, at a rate per annum equal to the Federal Funds
Rate in effect from time to time.

      3.05     Role of the Issuing Bank.  (a) Each Bank and the Company agree
               ------------------------                                      
that, in paying any drawing under a Letter of Credit, the Issuing Bank shall not
have any responsibility to obtain any document (other than any sight draft and
any other documentation expressly required by the Letter of Credit) or to
ascertain or inquire as to the validity or accuracy of any such document or the
authority of the Person executing or delivering any such document.

          (b) No Agent-Related Person nor any of the respective correspondents,
participants or assignees of the Issuing Bank shall be liable to any Bank for:
(i) any action taken or omitted in connection herewith at the request or with
the approval of the Banks (including the Required Banks, as applicable); (ii)
any action taken or omitted in the absence of gross negligence or willful
misconduct; or (iii) the due execution, effectiveness, validity or
enforceability of any L/C-Related Document.

          (c) The Company hereby assumes all risks of the acts or omissions of
any beneficiary or transferee with respect to its use of any Letter of Credit;
provided, however, that this assumption is not intended to, and shall not,
--------                                                                  
preclude the Company's pursuing such rights and remedies as it may have against
the beneficiary or transferee at law or under any other agreement.  No Agent-
Related Person, nor any of the respective correspondents, participants or
assignees of the Issuing Bank, shall be liable or responsible for any of the
matters described in clauses (i) through (vii) of Section 3.06; provided,
                                                                -------- 
however, anything in such clauses to the contrary notwithstanding, that the
Company may have a claim against the Issuing Bank, and the Issuing Bank may be
liable to the Company, to the extent, but only to the extent, of any direct, as
opposed to consequential or exemplary, damages suffered by the Company which the
Company proves were caused by the Issuing Bank's willful misconduct or gross
negligence or the Issuing Bank's willful failure to pay under any Letter of
Credit after the presentation to it by the beneficiary of a sight draft and
certificate(s) strictly complying with the terms and conditions of a Letter of
Credit.  In furtherance and not in limitation of the foregoing: (i) the Issuing
Bank may accept documents that appear on their face to be in order, without
responsibility for further investigation, regardless of any notice or
information to the contrary; and (ii) the Issuing Bank shall not be responsible
for the validity or sufficiency of any instrument transferring or assigning or
purporting to transfer or assign a Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason.

     beneficiary or any such transferee may be acting), the Issuing Bank or any
     other Person, whether in connection with this Agreement, the transactions
     contemplated hereby or by the L/C-Related Documents or any unrelated
     transaction;

               (iv)  any draft, demand, certificate or other document presented

                                   ARTICLE IV

                     TAXES, YIELD PROTECTION AND ILLEGALITY
                     --------------------------------------

      4.01     Taxes.  (a)  Any and all payments by the Company to each Bank or
               -----                                                           
the Agent under this Agreement and any other Loan Document shall be made free
and clear of, and without deduction or withholding for, any Taxes.  In addition,
the Company shall pay all Other Taxes.

          (b) If the Company shall be required by law to deduct or withhold any
Taxes, Other Taxes or Further Taxes from or in respect of any sum payable
hereunder to any Bank or the Agent, then:

               (i)  the sum payable shall be increased as necessary so that,
     after making all required deductions and withholdings (including deductions
     and withholdings applicable to additional sums payable under this Section),
     such Bank or the Agent, as the case may be, receives and retains an amount
     equal to the sum it would have received and retained had no such deductions
     or withholdings been made;

               (ii)  the Company shall make such deductions and withholdings;

               (iii)  the Company shall pay the full amount deducted or withheld
     to the relevant taxing authority or other authority in accordance with
     applicable law; and

               (iv)  the Company shall also pay to each Bank or the Agent for
     the account of such Bank, at the time interest is paid, Further Taxes in
     the amount that the respective Bank specifies as necessary to preserve the
     after-tax yield the Bank would have received if such Taxes, Other Taxes or
     Further Taxes had not been imposed.

          (c) The Company agrees to indemnify and hold harmless each Bank and
the Agent for the full amount of i) Taxes, ii) Other Taxes, and iii) Further
Taxes in the amount that the respective Bank specifies as necessary to preserve
the after-tax yield the Bank would have received if such Taxes, Other Taxes or
Further Taxes had not been imposed, and any liability (including penalties,
interest, additions to tax and expenses) arising therefrom or with respect
thereto, whether or not such Taxes, Other Taxes or Further Taxes were correctly
or legally asserted.  Payment under this indemnification shall be made within
thirty (30) days after the date the Bank or the Agent makes written demand
therefor.

          (d) Within thirty (30) days after the date of any payment by the
Company of Taxes, Other Taxes or Further Taxes, the Company shall furnish to
each Bank or the Agent the original or a certified copy of a receipt evidencing
payment thereof, or other evidence of payment satisfactory to such Bank or the
Agent.

                                      -48-
<PAGE>
 
          (e) If the Company is required to pay any amount to any Bank or the
Agent pursuant to Section (b) or (c) of this Section 4.01, then such Bank shall
use reasonable efforts (consistent with legal and regulatory restrictions) to
change the jurisdiction of its Lending Office so as to eliminate any such
additional payment by the Company which may thereafter accrue, if such change in
the sole judgment of such Bank is not otherwise disadvantageous to such Bank.

          (f) Notwithstanding anything herein to the contrary in Section 10.10
and in furtherance of such Section, each Bank organized under the laws of a
jurisdiction outside the United States, before it signs and delivers this
Agreement in the case of each Bank listed on the signature pages hereof and
before it becomes a Bank in the case of each other Bank, and from time to time
thereafter (unless such Bank can no longer do so due to a change in treaty, law
or regulation), before the date that any such form expires or becomes obsolete
or invalid, shall provide each of the Company and the Agent with IRS from 1001
or 4224 in duplicate, as appropriate, or any successor form prescribed by the
IRS, certifying that such Bank is entitled to benefits under an income tax
treaty to which the United States is a party which exempts the Bank from United
States withholding tax on payments of interest for the account of such Bank or
certifying that the income receivable pursuant to this Agreement is effectively
connected with the conduct of such Bank's trade or business in the United States
and exempt from United States withholding tax.  Each such Bank that so delivers
a form 1001 or 4224 (or applicable successor forms) agrees to deliver to the
Company undated or modified forms, or other manner of certification acceptable
to the Company, at any time that any such form is required to be resubmitted or
modified, as a result of any action taken by Bank, as a condition to obtaining
an exemption from withholding tax.  In addition, each Bank that so delivers a
form 1001 shall thereby be deemed to have made a representation to the effect
that the fees to be received by such Bank pursuant to this Agreement will not be
received in connection with the active conduct of a trade or business in the
United States by such Bank.

          (g) For any period with respect to which a Bank has failed to provide
the Company and the Agent with the appropriate form referred to in Section
4.01(f) (whether or not such Bank is lawfully able to do so, unless such failure
is due to a change in treaty, law or regulation occurring after the date on
which such form originally was required to be provided), such Bank shall not be
entitled to any additional payment under Section 4.01(b) or any indemnification
under Section 4.01(c); provided, that if such Bank shall have satisfied such
                       --------                                             
requirements on the Closing Date (in the case of each Bank listed on the
signature pages hereof) or on the effective date of the Assignment and
Acceptance Agreement or other document pursuant to which it became a Bank (in
the case of each other Bank), nothing in this subsection shall relieve the
Company of its obligation to pay any additional amounts pursuant to Section
4.01(b) or Section 4.01(c) in the event that, as a result of any change in
applicable law or treaty, such Bank is no longer properly entitled to deliver
certificates, documents or other evidence at a subsequent date establishing the
fact that such Bank is entitled to such exemption or reduced rate.

      4.02     Illegality.  (a) If any Bank determines that the introduction of
               ----------                                                      
any Requirement of Law, or any change in any Requirement of Law, or in the
interpretation 

                                      -49-
<PAGE>
 
or administration of any Requirement of Law, has made it unlawful, or that any
central bank or other Governmental Authority has asserted that it is unlawful,
for any Bank or its applicable Lending Office to make Offshore Rate Loans, then,
on notice thereof by the Bank to the Company through the Agent, any obligation
of that Bank to make Offshore Rate Loans shall be suspended until the Bank
notifies the Agent and the Company that the circumstances giving rise to such
determination no longer exist.

          (b) If a Bank determines that it is unlawful to maintain any Offshore
Rate Loan, the Company shall, upon its receipt of notice of such fact and demand
from such Bank (with a copy to the Agent), prepay in full such Offshore Rate
Loans of that Bank then outstanding, together with interest accrued thereon and
amounts required under Section 4.04, either on the last day of the Interest
Period thereof, if the Bank may lawfully continue to maintain such Offshore Rate
Loans to such day, or immediately, if the Bank may not lawfully continue to
maintain such Offshore Rate Loan.  If the Company is required to so prepay any
Offshore Rate Loan, then concurrently with such prepayment, the Company shall
borrow from the affected Bank, in the amount of such repayment, a Base Rate
Loan.

          (c) If the obligation of any Bank to make or maintain Offshore Rate
Loans has been so terminated or suspended, the Company may elect, by giving
notice to the Bank through the Agent that all Loans which would otherwise be
made by the Bank as Offshore Rate Loans shall be instead Base Rate Loans.

          (d) Before giving any notice to the Agent under this Section, the
affected Bank shall designate a different Lending Office with respect to its
Offshore Rate Loans if such designation will avoid the need for giving such
notice or making such demand and will not, in the judgment of the Bank, be
illegal or otherwise disadvantageous to the Bank.

      4.03     Increased Costs and Reduction of Return.  (a) If any Bank
               ---------------------------------------                  
determines that, due to either (i) the introduction of or any change in or in
the interpretation of any law or regulation or (ii) the compliance by that Bank
with any guideline or request from any central bank or other Governmental
Authority (whether or not having the force of law), there shall be any increase
in the cost to such Bank of agreeing to make or making, funding or maintaining
any Offshore Rate Loans or participating in Letters of Credit, or, in the case
of the Issuing Bank, any increase in the cost to the Issuing Bank of agreeing to
issue, issuing or maintaining any Letter of Credit or of agreeing to make or
making, funding or maintaining any unpaid drawing under any Letter of Credit,
then the Company shall be liable for, and shall from time to time, upon demand
(with a copy of such demand to be sent to the Agent), pay to the Agent for the
account of such Bank, additional amounts as are sufficient to compensate such
Bank for such increased costs.

          (b) If any Bank shall have determined that (i) the introduction of any
Capital Adequacy Regulation, (ii) any change in any Capital Adequacy Regulation,
(iii) any change in the interpretation or administration of any Capital Adequacy
Regulation by any central bank or other Governmental Authority charged with the
interpretation or administration thereof, or (iv) compliance by the Bank (or its
Lending Office) or any 

                                      -50-
<PAGE>
 
corporation controlling the Bank with any Capital Adequacy Regulation, affects
or would affect the amount of capital required or expected to be maintained by
the Bank or any corporation controlling the Bank and (taking into consideration
such Bank's or such corporation's policies with respect to capital adequacy and
such Bank's desired return on capital) determines that the amount of such
capital is increased as a consequence of its Commitments, loans, credits or
obligations under this Agreement, then, upon demand of such Bank to the Company
through the Agent, the Company shall pay to the Bank, from time to time as
specified by the Bank, additional amounts sufficient to compensate the Bank for
such increase.

      4.04     Funding Losses.  The Company shall reimburse each Bank and hold
               --------------                                                 
each Bank harmless from any loss or expense which the Bank may sustain or incur
as a consequence of:

          (a) the failure of the Company to make on a timely basis any payment
of principal of any Offshore Rate Loan;

          (b) the failure of the Company to borrow, continue or convert a Loan
after the Company has given (or is deemed to have given) a Notice of Borrowing
or a Notice of Conversion/Continuation;

          (c) the failure of the Company to make any prepayment in accordance
with any notice delivered under Section 2.06;

          (d) the prepayment (including pursuant to Section 2.07) or other
payment (including after acceleration thereof) of an Offshore Rate Loan on a day
that is not the last day of the relevant Interest Period; or

          (e) the automatic conversion under Section 2.04 of any Offshore Rate
Loan to a Base Rate Loan on a day that is not the last day of the relevant
Interest Period;

including any such loss or expense arising from the liquidation or reemployment
of funds obtained by it to maintain its Offshore Rate Loans or from fees payable
to terminate the deposits from which such funds were obtained.  For purposes of
calculating amounts payable by the Company to the Banks under this Section and
under Section 4.03(a), each Offshore Rate Loan made by a Bank (and each related
reserve, special deposit or similar requirement) shall be conclusively deemed to
have been funded at the LIBOR used in determining the Offshore Rate for such
Offshore Rate Loan by a matching deposit or other borrowing in the interbank
eurodollar market for a comparable amount and for a comparable period, whether
or not such Offshore Rate Loan is in fact so funded.

      4.05     Inability to Determine Rates.  If the Agent determines that for
               ----------------------------                                   
any reason adequate and reasonable means do not exist for determining the
Offshore Rate for any requested Interest Period with respect to a proposed
Offshore Rate Loan, or that the Offshore Rate applicable pursuant to Section
2.09(a) for any requested Interest Period with respect to a proposed Offshore
Rate Loan does not adequately and fairly reflect the cost to the Banks of
funding such Loan, the Agent will promptly so notify the Company 

                                      -51-
<PAGE>
 
and each Bank. Thereafter, the obligation of the Banks to make or maintain
Offshore Rate Loans hereunder shall be suspended until the Agent, upon the
instruction of the Required Banks, revokes such notice in writing. Upon receipt
of such notice, the Company may revoke any Notice of Borrowing or Notice of
Conversion/Continuation then submitted by it. If the Company does not revoke
such Notice, the Banks shall make, convert or continue the Loans, as proposed by
the Company, in the amount specified in the applicable notice submitted by the
Company, but such Loans shall be made, converted or continued as Base Rate Loans
instead of Offshore Rate Loans.

      4.06     Reserves on Offshore Rate Loans.  The Company shall pay to each
               -------------------------------                                
Bank, as long as such Bank shall be required under regulations of the FRB to
maintain reserves with respect to liabilities or assets consisting of or
including Eurocurrency funds or deposits (currently known as "Eurocurrency
liabilities"), additional costs on the unpaid principal amount of each Offshore
Rate Loan equal to the actual costs of such reserves allocated to such Loan by
the Bank (as determined by the Bank in good faith, which determination shall be
conclusive), payable on each date on which interest is payable on such Loan,
provided the Company shall have received at least 15 days' prior written notice
(with a copy to the Agent) of such additional interest from the Bank.  If a Bank
fails to give notice 15 days prior to the relevant Interest Payment Date, such
additional interest shall be payable 15 days from receipt of such notice.

      4.07     Certificates of Banks.  Any Bank claiming reimbursement or
               ---------------------                                     
compensation under this Article IV shall deliver to the Company (with a copy to
the Agent) a certificate setting forth in reasonable detail the computations in
determining the amount payable to the Bank hereunder and such certificate shall
be conclusive and binding on the Company in the absence of manifest error.

      4.08     Substitution of Banks.  Upon the receipt by the Company from any
               ---------------------                                           
Bank (an "Affected Bank") of a claim for compensation under Sections 4.01 and
          -------------                                                      
4.03, the Company may:  (i) request the Affected Bank to use commercially
reasonable efforts to obtain a replacement bank or financial institution
satisfactory to the Company to acquire and assume all or a ratable part of all
of such Affected Bank's Loans and Commitment (a "Replacement Bank"); (ii)
                                                 ----------------        
request one more of the other Banks to acquire and assume all or part of such
Affected Bank's Loans and Commitment; or (iii) designate a Replacement Bank.
Any such designation of a Replacement Bank under clause (i) or (iii) shall be
subject to the prior written consent of the Agent (which consent shall not be
unreasonably withheld).

      4.09     Survival.  The agreements and obligations of the Company in this
               --------                                                        
Article IV shall survive the payment of all other Obligations.

The Company acknowledges that the Agent and each Bank are entering into this
Agreement and are extending the Commitments in reliance upon the subordination
provisions of the Subordinated Notes and this Section 6.21.

Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or

foregoing sentence, the use of the term "agent" in this Agreement with reference
to the Agent is not intended to represent or connote any fiduciary or other
implied (or express) obligations arising under agency doctrine of any applicable
law.  Instead, such term is used merely as a matter of market custom, and is

independent contracting parties.

provided to the Agent in this Article X with respect to any acts taken or
omissions suffered by the Issuing Bank in connection with Letters of Credit
Issued by it or proposed to be Issued by it and the application and agreements
for letters of credit pertaining to the Letters of Credit as fully as if the
term "Agent," as used in this Article X, included the Issuing Bank with respect
to such acts or omissions, and (ii) as additionally provided in this Agreement
with respect to the Issuing Bank.

in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of the Company or any other party to
any Loan Document to perform its obligations hereunder or thereunder.  No Agent-
Related Person shall be under any obligation to any Bank to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or conditions of, this Agreement or any other Loan Document, or to inspect
the properties, books or records of the Company or any of the Company's
Subsidiaries or Affiliates.

action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Banks as it deems appropriate
and, if it so requests, it shall first be indemnified to its satisfaction by the
Banks against any and all liability and expense which may be incurred by it by
reason of taking or continuing to take any such action.  The Agent shall in all
cases be fully protected in acting, or in

accordance with a request or consent of the Required Banks and such request and

the Banks.

          (b) For purposes of determining compliance with the conditions
specified in Section 5.01, each Bank that has executed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by the Agent to such Bank for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to the Bank.

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

      10.06    Credit Decision.  Each Bank acknowledges that none of the Agent-
               ---------------                                                
Related Persons has made any representation or warranty to it, and that no act
by the Agent hereinafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank.  Each Bank represents to
the Agent that it has, independently and without reliance upon any Agent-Related
Person and based on such documents and information as it has deemed appropriate,
made its own appraisal of and investigation into the business, prospects,
operations, property, financial and other condition and creditworthiness of the
Company and its Subsidiaries, and all applicable bank regulatory laws relating
to the transactions contemplated hereby, and made its own decision to enter into
this Agreement and to extend credit to the Company hereunder.  Each Bank also
represents that it will, independently and without reliance upon any Agent-
Related Person and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Agreement and the other
Loan Documents, and to make such investigations as it deems necessary to inform
itself as to the business, prospects, operations, property, financial and other
condition and creditworthiness of the Company.  Except for notices, reports and
other documents expressly herein required to be furnished to the Banks by the
Agent, the Agent shall not have any duty or responsibility to provide any Bank
with any credit or other information concerning the business, prospects,
operations, property, financial and other condition or creditworthiness of the
Company which may come into the possession of any of the Agent-Related Persons.

      10.07    Indemnification of Agent.  Whether or not the transactions
               ------------------------                                  
contemplated hereby are consummated, the Banks shall indemnify upon demand the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Company and without limiting the obligation of the Company to do so), pro rata,
from and against any and all Indemnified Liabilities; provided, however, that no
                                                      --------  -------         
Bank shall be liable for the payment to the Agent-Related Persons of any portion
of such Indemnified Liabilities resulting from such Person's gross negligence or
willful misconduct.  Without limitation of the foregoing, each Bank shall
reimburse the Agent upon demand for its ratable share of any costs or out-of-
pocket expenses (including Attorney Costs) incurred by the Agent in connection
with the preparation, execution, delivery, administration, modification,
amendment or enforcement (whether through negotiations, legal proceedings or
otherwise) of, or legal advice in respect of rights or responsibilities under,
this Agreement, any other Loan Document, or any document contemplated by or
referred to herein, to the extent that the Agent is not reimbursed for such
expenses by or on behalf of the Company.  The undertaking in this Section shall
survive the payment of all Obligations hereunder and the resignation or
replacement of the Agent.

      10.08    Agent in Individual Capacity.  BofA and its Affiliates may make
               ----------------------------                                   
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the Company and its
Subsidiaries and Affiliates as though BofA were not the Agent or the Issuing
Bank hereunder and without notice to or consent of the Banks.  The Banks
acknowledge that, pursuant to such activities, BofA or its Affiliates may
receive information regarding the Company or its Affiliates (including
information that may be subject to confidentiality obligations in favor of the
Company or such Subsidiary) and acknowledge that the Agent shall be under no
obligation to provide such information to them.  With respect to its Loans, BofA
shall have the same rights and powers under this Agreement as any other Bank and
may exercise the same as though it were not the Agent or the Issuing Bank.

      10.09    Successor Agent.  The Agent may, and at the request of the
               ---------------                                           
Required Banks shall, resign as Agent upon 30 days' notice to the Banks.  If the
Agent resigns under this Agreement, the Required Banks shall appoint from among
the Banks, with the consent of the Company, which consent shall not be
unreasonably withheld, a successor agent for the Banks.  If no successor agent
is appointed prior to the effective date of the resignation of the Agent, the
Agent may appoint, after consulting with the Banks and the Company, a successor
agent from among the Banks.  Upon the acceptance of its appointment as successor
agent hereunder, such successor agent shall succeed to all the rights, powers
and duties of the retiring Agent and the term "Agent" shall mean such successor
agent and the retiring Agent's appointment, powers and duties as Agent shall be
terminated. After any retiring Agent's resignation hereunder as Agent, the
provisions of this Article X and Sections 11.04 and 11.05 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was Agent
under this Agreement.  If no successor agent has accepted appointment as Agent
by the date which is 30 days following a retiring Agent's notice of resignation,
the retiring Agent's resignation shall nevertheless thereupon become effective
and the Banks shall perform all of the duties of the Agent hereunder until such
time, if any, as the Required Banks appoint a successor 

                                      -84-
<PAGE>
 
agent as provided for above. Notwithstanding the foregoing, however, BofA may
not be removed as the Agent at the request of the Required Banks unless BofA
shall also be replaced simultaneously as "Issuing Bank" hereunder pursuant to
documentation in form and substance reasonably satisfactory to BofA.

      10.10    Withholding Tax.  (a)  If any Bank is a "foreign corporation,
               ---------------                                              
partnership or trust" within the meaning of the Code and such Bank claims
exemption from, or a reduction of, U.S. withholding tax under Sections 1441 or
1442 of the Code, such Bank agrees with and in favor of the Agent, to deliver to
the Agent:

               (i) if such Bank claims an exemption from, or a reduction of,
     withholding tax under a United States tax treaty, two properly completed
     and executed copies of IRS Form 1001 before the payment of any interest in
     the first calendar year and before the payment of any interest in each
     third succeeding calendar year during which interest may be paid under this
     Agreement;

               (ii) if such Bank claims that interest paid under this Agreement
     is exempt from United States withholding tax because it is effectively
     connected with a United States trade or business of such Bank, two properly
     completed and executed copies of IRS Form 4224 before the payment of any
     interest is due in the first taxable year of such Bank and in each
     succeeding taxable year of such Bank during which interest may be paid
     under this Agreement; and

               (iii) such other form or forms as may be required under the Code
     or other laws of the United States as a condition to exemption from, or
     reduction of, United States withholding tax.

Such Bank agrees to notify promptly the Agent of any change in circumstances
which would modify or render invalid any claimed exemption or reduction.

          (b)  If any Bank claims exemption from, or reduction of, withholding
tax under a United States tax treaty by providing IRS Form 1001 and such Bank
sells, assigns, grants a participation in, or otherwise transfers all or part of
the Obligations of the Company to such Bank, such Bank agrees to notify the
Agent of the percentage amount in which it is no longer the beneficial owner of
Obligations of the Company to such Bank.  To the extent of such percentage
amount, the Agent will treat such Bank's IRS Form 1001 as no longer valid.

          (c) If any Bank claiming exemption from United States withholding tax
by filing IRS Form 4224 with the Agent sells, assigns, grants a participation
in, or otherwise transfers all or part of the Obligations of the Company to such
Bank, such Bank agrees to undertake sole responsibility for complying with the
withholding tax requirements imposed by Sections 1441 and 1442 of the Code.

          (d) If any Bank is entitled to a reduction in the applicable
withholding tax, the Agent may withhold from any interest payment to such Bank
an amount equivalent to the applicable withholding tax after taking into account
such reduction. 

                                      -85-
<PAGE>
 
However, if the forms or other documentation required by Section (a) of this
Section are not delivered to the Agent, then the Agent may withhold from any
interest payment to such Bank not providing such forms or other documentation an
amount equivalent to the applicable withholding tax imposed by Sections 1441 and
1442 of the Code, without reduction.

          (e) If the IRS or any other Governmental Authority of the United
States or other jurisdiction asserts a claim that the Agent did not properly
withhold tax from amounts paid to or for the account of any Bank (because the
appropriate form was not delivered or was not properly executed, or because such
Bank failed to notify the Agent of a change in circumstances which rendered the
exemption from, or reduction of, withholding tax ineffective, or for any other
reason) such Bank shall indemnify the Agent fully for all amounts paid, directly
or indirectly, by the Agent as tax or otherwise, including penalties and
interest, and including any taxes imposed by any jurisdiction on the amounts
payable to the Agent under this Section, together with all costs and expenses
(including Attorney Costs).  The obligation of the Banks under this Section
shall survive the payment of all Obligations and the resignation or replacement
of the Agent.

      10.11    Senior Managing Agents; Co-Agents.  None of the Banks identified
               ---------------------------------                               
on the facing page or signature pages of this Agreement as a "senior managing
agent" or a "co-agent" 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
as a "senior managing agent" or a "co-agent" 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.

departure by the Company or any applicable Subsidiary therefrom, shall be

officers, directors, employees, counsel, agents and attorneys-in-fact (each, an
"Indemnified Person") harmless from and against any and all liabilities,

termination, resignation or replacement of the Agent or replacement of any Bank)
be imposed on, incurred by or asserted against any such Person in any way
relating to or arising out of this Agreement or any document contemplated by or
referred to herein, or the transactions contemplated hereby, or any action taken
or omitted by any such Person under or in connection with any of the foregoing,

this Agreement or the Loans or Letters of Credit or the use of the proceeds
thereof, whether or not any Indemnified Person is a party thereto (all the
foregoing, collectively, the "Indemnified Liabilities"); provided, that the
                              -----------------------    --------          
Company shall have no obligation hereunder to any Indemnified Person with
respect to Indemnified Liabilities resulting solely from the gross negligence or
willful misconduct of such Indemnified Person. The agreements in this Section
shall survive payment of all other Obligations.

      11.06    Payments Set Aside.  To the extent that the Company makes a
               ------------------                                         
payment to the Agent or the Banks, or the Agent or the Banks exercise their
right of set-off, and such payment or the proceeds of such set-off or any part
thereof are subsequently invalidated, declared to be fraudulent or preferential,
set aside or required (including pursuant to any settlement entered into by the
Agent or such Bank in its discretion) to be repaid to a trustee, receiver or any
other party, in connection with any Insolvency Proceeding or otherwise, then (a)
to the extent of such recovery the obligation or part thereof originally
intended to be satisfied shall be revived and continued in full force and effect
as if such payment had not been made or such set-off had not occurred, and (b)
each Bank severally agrees to pay to the Agent upon demand its pro rata share of
any amount so recovered from or repaid by the Agent.

      11.07    Successors and Assigns.  The provisions of this Agreement shall

be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns, except that the Company may not assign or
transfer any of its rights or obligations under this Agreement without the prior
written consent of the Agent and each Bank.

      11.08    Assignments, Participations, etc.  (a) With the written consent
               ---------------------------------                              
of the Company (at all times other than during the existence of an Event of
Default) and the Agent [and the Issuing Bank,] which consents shall not be
unreasonably withheld, any Bank may, at any time, assign and delegate to one or
more Eligible Assignees (provided that no written consent of the Company, the
Agent or the Issuing Bank shall be required in connection with any assignment
and delegation by a Bank to an Eligible Assignee that is a Bank or an Affiliate
of a Bank) (each an "Assignee") all, or any ratable part of all, of the Loans,
                     --------                                                 
the Commitments, the L/C Obligations and the other rights and obligations of

                                      -89-
<PAGE>
 
such Bank hereunder, in a minimum amount of  $5,000,000 and so long as, after
giving effect thereto, the Bank's remaining Commitment is either (i) equal to or
greater than $5,000,000 or (ii) zero; provided, however, that the Company and
                                      --------  -------                      
the Agent may continue to deal solely and directly with such Bank in connection
with the interest so assigned to an Assignee until (X) written notice of such
assignment, together with payment instructions, addresses and related
information with respect to the Assignee, shall have been given to the Company
and the Agent by such Bank and the Assignee; (Y) such Bank and its Assignee
shall have delivered to the Company and the Agent an Assignment and Acceptance
in the form of Exhibit F ("Assignment and Acceptance") together with any Note or
               ---------   -------------------------                            
Notes subject to such assignment and (Z) the assignor Bank or Assignee has paid
to the Agent a processing fee in the amount of $3,000.

          (b) From and after the date that the Agent notifies the assignor Bank
that it has received (and provided its consent with respect to) an executed
Assignment and Acceptance and payment of the above-referenced processing fee,
(i) the Assignee thereunder shall be a party hereto and, to the extent that
rights and obligations hereunder have been assigned to it pursuant to such
Assignment and Acceptance, shall have the rights and obligations of a Bank under
the Loan Documents, and (ii) the assignor Bank shall, to the extent that rights
and obligations hereunder and under the other Loan Documents have been assigned
by it pursuant to such Assignment and Acceptance, relinquish its rights and be
released from its obligations under the Loan Documents.

          (c) Within five Business Days after its receipt of notice by the Agent
that it has received an executed Assignment and Acceptance and payment of the
processing fee, (and provided that it consents to such assignment in accordance
with Section 11.08(a)), the Company shall execute and deliver to the Agent, new
Notes evidencing such Assignee's assigned Loans and Commitment and, if the
assignor Bank has retained a portion of its Loans and its Commitment,
replacement Notes in the principal amount of the Loans retained by the assignor
Bank (such Notes to be in exchange for, but not in payment of, the Notes held by
such Bank).  Immediately upon each Assignee's making its processing fee payment
under the Assignment and Acceptance, this Agreement shall be deemed to be
amended to the extent, but only to the extent, necessary to reflect the addition
of the Assignee and the resulting adjustment of the Commitments arising
therefrom. The Commitment allocated to each Assignee shall reduce such
Commitments of the assigning Bank pro tanto.
                                  --- ----- 

          (d) Any Bank may at any time sell to one or more commercial banks or
other Persons not Affiliates of the Company (a "Participant") participating
                                                -----------                
interests in any Loans, the Commitment of that Bank and the other interests of
that Bank (the "originating Bank") hereunder and under the other Loan Documents;
                                                                                
provided, however, that (i) the originating Bank's obligations under this
--------  -------                                                        
Agreement shall remain unchanged, (ii) the originating Bank shall remain solely
responsible for the performance of such obligations, (iii) the Company, the
Issuing Bank and the Agent shall continue to deal solely and directly with the
originating Bank in connection with the originating Bank's rights and
obligations under this Agreement and the other Loan Documents, and (iv) no Bank
shall transfer or grant any participating interest under which the Participant
has rights to approve any amendment to, or any consent or waiver with respect
to, this

<PAGE>
 
Agreement or any other Loan Document, except to the extent such amendment,
consent or waiver would require unanimous consent of the Banks as described in
the first proviso to Section 11.01. In the case of any such participation, the
    ----- -------                                          
Participant shall be entitled to the benefit of Sections 4.01, 4.03 and 11.05 as
though it also were a Bank hereunder, and if amounts outstanding under this
Agreement are due and unpaid, or shall have been declared or shall have become
due and payable upon the occurrence of an Event of Default, each Participant
shall be deemed to have the right of set-off in respect of its participating
interest in amounts owing under this Agreement to the same extent as if the
amount of its participating interest were owing directly to it as a Bank under
this Agreement.

          (e) Notwithstanding any other provision in this Agreement, any Bank
may at any time create a security interest in, or pledge, all or any portion of
its rights under and interest in this Agreement and the Note held by it in favor
of any Federal Reserve Bank in accordance with Regulation A of the FRB or U.S.
Treasury Regulation 31 CFR (S)203.14, and such Federal Reserve Bank may enforce
such pledge or security interest in any manner permitted under applicable law.

      11.09    Confidentiality.  Each Bank agrees to take and to cause its
               ---------------                                            
Affiliates to take normal and reasonable precautions and exercise due care to
maintain the confidentiality of all information identified as "confidential" or
"secret" by the Company and provided to it by the Company or any Subsidiary, or
by the Agent on the Company's or such Subsidiary's behalf, under this Agreement
or any other Loan Document, and neither it nor any of its Affiliates shall use
any such information other than in connection with or in enforcement of this
Agreement and the other Loan Documents or in connection with other business now
or hereafter existing or contemplated with the Company or any Subsidiary; except
to the extent such information (i) was or becomes generally available to the
public other than as a result of disclosure by the Bank, or (ii) was or becomes
available on a non-confidential basis from a source other than the Company,
provided that such source is not bound by a confidentiality agreement with the
Company known to the Bank; provided, however, that any Bank may disclose such
                           --------  -------                                 
information (A) at the request or pursuant to any requirement of any
Governmental Authority to which the Bank is subject or in connection with an
examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (C) when required to do so in accordance with the
provisions of any applicable Requirement of Law; (D) to the extent reasonably
required in connection with any litigation or proceeding relating to this
Agreement and the transactions contemplated hereby to which the Agent, any Bank
or their respective Affiliates may be party; (E) to the extent reasonably
required in connection with the exercise of any remedy hereunder or under any
other Loan Document; (F) to such Bank's independent auditors and other
professional advisors; (G) to any Participant or Assignee, actual or potential,
with the prior consent of the Company, which consent shall not be unreasonably
withheld; provided, that such Person agrees in writing to keep such information
          ---------                                                            
confidential to the same extent required of the Banks hereunder; and (H) as to
any Bank or its Affiliate, as expressly permitted under the terms of any other
document or agreement regarding confidentiality to which the Company or any
Subsidiary is party or is deemed party with such Bank or such Affiliate.

      11.10    Set-off.  In addition to any rights and remedies of the Banks
               -------                                                      
provided by law, if an Event of Default exists or the Loans have been
accelerated, each Bank is authorized at any time and from time to time, without
prior notice to the Company, any such notice being waived by the Company to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held by,
and other indebtedness at any time owing by, such Bank to or for the credit or
the account of the Company against any and all Obligations owing to such Bank,
now or hereafter existing, irrespective of whether or not the Agent or such Bank
shall have made demand under this Agreement or any Loan Document and although
such Obligations may be contingent or unmatured.  Each Bank agrees promptly to
notify the Company and the Agent after any such set-off and application made by
such Bank; provided, however, that the failure to give such notice shall not
           --------  -------

notify the Agent in writing of any changes in the address to which notices to
the Bank should be directed, of addresses of any Lending Office, of payment
instructions in respect of all payments to be made to it hereunder and of such
other administrative information as the Agent shall reasonably request.

      11.12    Counterparts.  This Agreement may be executed in any number of
               ------------                                                  
separate counterparts, each of which, when so executed, shall be deemed an
original, and all of said counterparts taken together shall be deemed to
constitute but one and the same instrument.

      11.13    Severability.  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.

      11.14    No Third Parties Benefitted.  This Agreement is made and entered
               ---------------------------                                     
into for the sole protection and legal benefit of the Company, the Banks, the
Agent and the Agent-Related Persons, and their permitted successors and assigns,
and no other Person shall be a direct or indirect legal beneficiary of, or have
any direct or indirect cause of action or claim in connection with, this
Agreement or any of the other Loan Documents.

               ------------------------------                                   
SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF
CALIFORNIA; PROVIDED THAT THE AGENT AND THE BANKS SHALL RETAIN ALL RIGHTS
ARISING UNDER FEDERAL LAW.

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA
OR OF THE UNITED STATES FOR THE CENTRAL DISTRICT OF CALIFORNIA, AND BY EXECUTION
AND DELIVERY OF THIS AGREEMENT, EACH OF THE COMPANY, THE AGENT AND THE BANKS

JURISDICTION IN RESPECT OF THIS AGREEMENT OR ANY DOCUMENT RELATED HERETO. THE
COMPANY, THE AGENT AND THE BANKS EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS,

CALIFORNIA LAW.

      11.16    Waiver of Jury Trial.  THE COMPANY, THE BANKS AND THE AGENT EACH
               --------------------

BANKS AND THE AGENT EACH AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE
TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE
PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED
BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING
WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF
THIS AGREEMENT OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.

MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

Bank of America National Trust and 
  Savings Association, as Agent and Issuing Bank
the other Banks party to the herein
  referenced Credit Agreement

Ladies and Gentlemen:

     We have acted as counsel to CB Richard Ellis Services, Inc., a Delaware 
corporation (the "Company"), with respect to the negotiation and execution of 
                  -------
the Amended and Restated Credit Agreement (the "Credit Agreement") dated as of
                                                ----------------
May 20, 1998 among the Company, Bank of America National Trust and Savings
Association as Agent (in such capacity, the "Agent") and Issuing Bank and the
                                             -----
several financial institutions from time to time party to the Credit Agreement
(collectively, the "Banks"). This opinion is rendered pursuant to Section
                    -----
5.01(d)(i)(A) of the Credit Agreement. Capitalized terms not otherwise defined
herein shall have the meanings ascribed to them in the Credit Agreement.

     We have examined executed copies of the Credit Agreement, the Notes, the
Guaranty the Pledge Agreements. We have also examined such other documents,
certificates of public officials and representatives of the Company and
subsidiaries of the Company as we have deemed necessary as a basis for the
opinions expressed herein. As to questions of fact material to such opinions,
we have relied upon certificates of officers of the Company or its subsidiaries.

     We have assumed the genuineness of all signatures and documents submitted 
to us as originals, that all copies submitted to us conform to the originals, 
the legal capacity of all natural persons, and as to documents executed by
entities other than the Company and its Subsidiaries, that each such entity has
complied with any applicable requirement to file returns and pay taxes under the
California Franchise Tax law and had the power to enter into and perform its
obligations thereunder, and that such documents have been duly authorized,
executed and delivered by, and are binding upon and enforceable against, such
entities.

       We have assumed that each of the Banks is either a bank (i) organized 
under the laws of the United States or any State thereof, or (ii) licensed to 
maintain an office in California, or (iii) licensed or otherwise authorized by 
another State of the United States to maintain an agency or branch in such 
State, or (iv) which maintains a Federal agency or Federal branch in any State 
of the United States of America or (v) which has, and will have during the term 
of the Agreement, assets equal to at least $100,000,000, and, as a result 
thereof, is a lender exempt from the restrictions of Section 1 or Article XV of 
the Constitution of the State of California relating to rates of interest upon 
the loan of money.

       We express no opinion as to the laws of any jurisdiction other than the 
State of California, the corporation law of the State of Delaware and the 
Federal laws of the United States of America.

       Based upon the foregoing and subject to the assumptions set forth above 
and the qualifications set forth below, it is our opinion that:

       1.   The Company has been duly incorporated and is a validly existing 
       corporation in good standing under the laws of the State of Delaware, a
       duly qualified and in good standing as a foreign corporation authorized
       to do business in the State of California and, based solely upon
       certificates of its officers, is duly qualified and in good standing as a
       foreign corporation authorized to do business in each other state where
       the nature of its business activities conducted or properties owned or
       leased requires it to be so qualified except where the failure to be so
       qualified would not have a material adverse effect upon the business or
       financial condition of the Company. The Company has all requisite
       corporate power and authority to execute and deliver each of the Loan
       Documents to which it is a party and to perform is respective obligations
       thereunder.

       2.   Each of the Material Subsidiaries has been duly incorporated and is
       a validly existing corporation in good standing under the laws of the
       jurisdiction of its incorporation and, based solely upon certificates of
       its officers, is duly qualified and in good standing as a foreign
       corporation and authorized to do business in each state where the nature
       of its business activities conducted or properties owned or leased
       requires it to be so qualified except where the failure to be so
       qualified would not have a material adverse effect upon the respective
       business or financial condition of such Material Subsidiary. Each
       Material Subsidiary has all requisite corporate power and authority to
       execute, deliver and perform its obligations under the Guaranty.

    3.   Each of the Material Subsidiaries which has executed a Pledge 
    Agreement (collectively, the "Subsidiary Pledgors") has been duly
                                  -------------------
    incorporated and is a validly existing corporation in good standing under
    the laws of the jurisdiction of its incorporation and, based solely upon
    certificates of its officers, is duly qualified and in good standing as a
    foreign corporation and authorized to do business in each state where the
    nature of its business activities conducted or properties owned or leased
    requires it to be so qualified except where the failure to be so qualified
    would not have a material adverse effect upon the respective business or
    financial condition of such Subsidiary Pledgor. Each Subsidiary Pledgor has
    all requisite corporate power and authority to execute, deliver and perform
    its obligations under its respective Pledge Agreement. Each of Hold Par A, a
    Delaware general partnership, Hold Par B, a Delaware general partnership,
    Koll Real Estate Services, a Delaware corporation and Koll Von Karman, Inc.,
    a Delaware corporation (collectively, the "Other Pledgors"), has the
                                               --------------
    requisite power and authority to execute, deliver and perform its
    obligations under its respective Pledge Agreement.

    4.   The execution and delivery of each of the Loan Documents to which it is
    a party and performance by the Company of its obligations thereunder have
    been duly authorized by all necessary action on the part of the Company.

    5.   The execution and delivery of the Guaranty by the Material Subsidiaries
    and performance by the Material Subsidiaries of their respective obligations
    thereunder have been duly authorized by all necessary action on the part of
    each Material Subsidiary.

    6.   The execution and delivery of the Pledge Agreements by the Subsidiary 
    Pledgors and by the Other Pledgors and performance by the Subsidiary
    Pledgors and by the Other Pledgors of their respective obligations
    thereunder have been duly authorized by all necessary action on the part of
    each Subsidiary Pledgor and each Other Pledgor.

    7.   Each of the Loan Documents to which the Company is a Party constitutes 
    the legal, valid and binding obligation of the Company, enforceable against
    the Company in accordance with its respective terms. The Pledge Agreements
    constitute the legal, valid and binding obligations of the Subsidiary
    Pledgors and the Other Pledgors, respectively, enforceable against each
    Subsidiary Pledgor and each Other Pledgor, respectively, in accordance with
    their respective terms. The Guaranty constitutes the legal, valid and
    binding obligation of each of the Material Subsidiaries, enforceable against
    each Material Subsidiary in accordance with its terms.

     8. Upon filing a financing statement in proper form with respect thereto in
     the office of the California Secretary of State, a valid security interest
     in each of Koll Management Services, Inc.'s and Koll Von Karman, Inc.'s
     interests in Koll/CC&F Management Services in favor of the Agent for the
     benefit of the Banks will be perfected to the extent that a security
     interest in such collateral may be so perfected. So long as the agent (as
     such term is defined in the pledge Agreements) takes possession of and
     holds the stock certificates representing all of the Pledged Shares, which
     are being delivered to the Agent for the benefit of the Banks in accordance
     with the terms of the Pledge Agreements, together with undated stock powers
     duly endorsed in blank, the Pledge Agreements create a valid and perfected
     security interest in favor of the Agent, for the benfit of the Banks in the
     Pledged Shares, as security for the payment, to the extent set forth in the
     Pledge Agreements, of all the Obligations.

     9. None of the Company, any Material Subsidiary, any Subsidiary Pledgor or
     any Other Pledgor (i) is an "investment company" registered or required to
     be registered under the Investment Company Act of 1940, as amended, or a
     company controlled by such a company or (ii) is subject to regulation under
     the Public Utility Holding Company Act of 1934, the Federal Power Act, the
     Interstate Commerce Act or any other state or federal statute or
     regulation limiting its ability to incur debt for borrowed money.

     10. The execution, delivery and performance by the Company, each Material
     Subsidiary, each Subsidiary Pledgor and each Other Pledgor of each Loan
     Document to which it is a party do not and will not violate any law or
     regulation of the United States of America binding on any of them.

     11. The execution, delivery and performance by the Company, each Material
     Subsidiary and each Subsidiary Pledgor of each Loan Document to which it
     is a party do not an will not violate the charter or bylaws of any of them.
     The execution, delivery and performance by each Other Pledgor of the Pledge
     Agreements to which each is a party do not and will not violate the charter
     or bylaws or partnership agreements of any of them, as the case may be.

     12. The execution, delivery and performance by the Company, each Material
     Subsidiary, each Subsidiary Pledgor and each Other Pledgor of each Loan
     Document and each Subordinated Note Document to which it is a party do not
     and will not to our knowledge based upon certificates of appropriate
     officers (or as applicable, of appropriate partners) (a) violate any order,
     judgment or decree of any court or other governmental


<PAGE>
 
Bank of America National Trust and
 Savings Association, as Agent and Issuing Bank
and the other Banks party to the

May 26, 1998

       authority binding on any of them or (b) conflict with, result in a breach
       of, or constitute (where with a giving of notice or lapse of time or
       both, constitute) a default under, or require the approval or consent of
       any person pursuant to any contractual obligation of any of them.

       13.   To the best of our knowledge after due inquiry only of officers of 
       the Company, there are no actions, suits or proceedings at law or in
       equity pending, or threatened, at law, or in equity, against any of the
       Company or its Material Subsidiaries which purport to affect or pertain
       to any of the Loan Documents. Based solely upon certificates of its
       officers, no injunction, writ, temporary restraining order of any nature
       has been issued by any court of other Government Authority purporting to
       enjoin or restrain the execution, delivery or performance of any of the
       Loan Documents, or directing that the transactions provided for therein,
       not be consummated.

       The opinions set forth above are subject to the following qualifications:

       (a)   Our opinion in paragraph 7 above is subject to and limited by: (i) 
the effect of bankruptcy, insolvency, reorganization, receivership, 
conservatorship, arrangement, moratorium or other laws affecting or relating to 
the rights of creditors generally, (ii) the rules governing the availability of 
specific performance, injunctive relief or other equitable remedies and general 
principles of equity, regardless of whether considered in a proceeding in equity
or at law, (iii) the effect of applicable court decisions, invoking statutes or 
principles of equity, which have held that certain covenants and provisions of 
agreements are unenforceable where the breach of such covenants or provisions 
imposes restrictions or burdens upon a borrower, and it cannot be demonstrated 
that the enforcement of such restrictions or burdens is necessary for the 
protection of the creditor, or which have held that the creditor's enforcement 
of such covenants or provisions under the circumstances would violate the 
creditor's covenants of good faith and fair dealing implied under California law
and (iv) the effect of California statutes and rules of law which cannot be 
waived prospectively by a borrower. With respect to the Guaranty and the Pledge 
Agreements, our opinion is further subject to the effect of California statutes 
and cases to the effect that a surety may be exonerated if the creditor alters 
the original obligation of the principal without the surety's consent, elects
remedies for default that may impair the surety's subrogation rights against the
principal, or otherwise takes action which materially prejudices the surety, 
without notification of the surety, unless such rights of the surety are validly
waived. While we believe that a California court should hold that waivers of 
such rights contained in the Guaranty and the Pledge Agreements are enforceable,
we express no opinion with respect to the effect of any modification of the 
obligations of the Company which materially increases such
<PAGE>
 
Bank of America National Trust and
 Savings Association, as Agent and Issuing Bank
and the other Banks party to the 
 herein referenced Credit Agreement
May 26, 1998
Page 6

obligations, or any election of remedies by the Agent or the Lenders following
the occurrence of a default, or any other act by the Agent or the Lenders, which
materially prejudices any of the Material Subsidiaries or the Other Pledgors, if
such actions occur without notice and opportunity to cure being granted to such
subsidiary. We further advise you that if it could be contended that the
Guaranty and the Pledge Agreements have not been given for a fair or reasonably
equivalent consideration, or that any of the Material Subsidiaries or the Other
Pledgors executing the Guaranty or the Pledge Agreement may become insolvent and
that such documents are therefore voidable by creditors of such Subsidiary or by
a trustee or receiver of such Subsidiary in bankruptcy or similar proceedings
pursuant to applicable bankruptcy, fraudulent conveyance or similar laws. We
express no opinion as to any provision in the Credit Agreement which increases
the rate of interest or imposes any late charge or prepayment fee in the event
of a delinquency or default or other event, to the extent such increased rate or
charge or fee is found to constitute a penalty.

     (b)  Whenever a statement herein is qualified by "known to us," "to our 
knowledge," or similar phrase, it indicates that in the course of our 
representation of the Company no information that would give us current actual 
knowledge of the inaccuracy of such statement has come to the attention of the 
attorneys in this firm who have rendered legal services in connection with this 
transaction.  We have not made any independent investigation to determine the 
accuracy of such statement, except as expressly described herein.  No inference 
as to our knowledge of any matters bearing on the accuracy of such statement 
should be drawn from the fact of our representation of the Company in other 
matters in which such attorneys are not involved.

     This opinion is rendered solely for your benefit and may not be used,
circulated, quoted or relied upon for any other purpose without our prior
written consent except that you may provide this opinion to (i) bank examiners
and other regulatory authorities should they so request, (ii) in accordance with
their normal examinations, to your independent auditors or attorneys, (iii)
pursuant to legal process, or (iv) in connection with any legal action to which
you are a party arising out of the transactions contemplated by any of the
documents referenced herein. In addition, we advise you that we accede to your
request to provide a copy of this opinion to any person in connection with
assignment of, or any sale of a participating interest in, any of the loans
under the Credit Agreement without any right to rely thereon.

                                         Very truly yours,

BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION, AS AGENT

THE OTHER BANKS PARTY TO THE HEREIN REFERENCED CREDIT AGREEMENT

Ladies and Gentlemen:

I am the general counsel of CB Richard Ellis Services, Inc., a Delaware 
corporation (the "Company").  I have acted as counsel to the Company in 
                  -------
connection with the Amended and Restated Credit Agreement dated as of May 20, 
1998 among the Company, Bank of America National Trust and Savings Association 
as Agent and the other financial institutions party thereto (the "Credit 
                                                                  ------
Agreement"; all capitalized terms used and not otherwise defined herein shall
---------
have the same meanings as set forth in the Credit Agreement). I have also acted
as counsel to the Company in connection with the transactions contemplated by
the Subordinated Note Documents (such transactions, the "Offering"). This
                                                         --------
opinion is rendered to the Agent and each Bank pursuant to Section 5.01(d)(i)(B)
of the Credit Agreement.

I have examined executed copies of the Subordinated Note Documents.  I have 
also examined such other documents and certificates of public officials and 
representatives of the Company as I have deemed necessary for the opinions 
expressed below. As to questions of fact material to such opinions, I have
relied upon certificates of officers of the Company when relevant facts were not
independently established.

I have assumed the genuineness of all signatures and documents submitted as 
originals and that all copies submitted to us conform to the originals.

I assume that no party to any Subordinated Note Document knows of any
agreements, understandings or negotiations between the parties not set forth in
the Subordinated Note Documents that would modify the terms or rights and
obligations of the parities thereunder.

I express no opinion as to the laws of any jurisdiction other than California,
the corporate law of the State of Delaware and the federal securities law of the
United States.

Based upon the foregoing and subject to the qualifications set forth below, it 
is my opinion that:

1.   The Company has the power and authority (corporate or otherwise) to execute
     and deliver the Subordinated Note Documents to which it is party and to
     perform its obligations thereunder. The Company has taken all necessary
     action to authorize the execution, delivery and performance by it of such
     Subordinated Note Documents.

2.   The Company has duly executed and delivered any Subordinated Note Document
     to which it is party and such Subordinated Note Document constitutes the
     legal, valid and binding obligation of the Company, enforceable against the
     Company in accordance with its terms.

3.   Upon consummation of the Offering, the Offering shall become effective at
     the effective time as set forth in the Subordinated Note Documents, in
     accordance with the terms and provisions of the Subordinated Note
     Documents.

The opinions set forth above are subject to the following qualifications:

     a.   The opinion in paragraph 2. above is subject to and limited by:

          i.    the effect of bankruptcy, insolvency, reorganization,
                receivership, conservatorship, arrangement, moratorium or other
                laws affecting or relating to the rights of creditors generally;

          ii.   the rules governing the availability of specific performance,
                injunctive relief or other equitable remedies and general
                principles of equity, regardless of whether considered in a
                proceeding in equity or at law;

          iii.  the effect of applicable court decisions, invoking statutes or
                principles of equity, which have held that certain covenants and
                provisions of agreements are unenforceable where the breach of
                such covenants or provisions imposes restrictions or burdens
                upon an obligor, and it cannot be demonstrated that the
                enforcement of such restrictions or burdens is necessary for the
                protection of the creditor, or which have held that the
                creditor's enforcement of such covenants or provisions under the
                circumstances would violate the creditor's covenants of good
                faith and fair dealing implied under California law;

          iv.   the effect of statutes and rules of law which cannot be waived 
                prospectively by an obligor or;

                  Re: CB Richard Ellis Services Inc,
                      Amended and Restated Credit Agreement
                      -------------------------------------

Ladies and Gentlemen:

     We have acted as counsel for Bank of America National Trust and Savings
Association, in its capacity as agent under the Credit Agreement referenced
below (in such capacity, the "Agent") in connection with the negotiation,
execution and delivery of the Amended and Restated Credit Agreement, dated as of
May 20, 1998 (the "Credit Agreement"), by and among CB Richard Ellis Services,
Inc., a Delaware corporation (the "Borrower"), the banks parties thereto
(individually a "Bank" and collectively, the "Banks"), and, Agent thereunder,
and the other agreements and documents referred to therein. This opinion is
being given pursuant to Section 5.01(d)(ii) of the Credit Agreement.
Capitalized terms used herein without definition shall have the meaning ascribed
to such terms in the Credit Agreement.

     We have participated in various conferences with representatives of the 
Borrower, Pillsbury Madison & Sutro LLP, counsel for each of the Borrower, its 
Material Subsidiaries and each of the pledgors under the Pledge Agreements (the
"Subsidiaries"), and with your representatives, during which the Credit
Agreement and
<PAGE>

related matters have been discussed, and we also have participated in the 
meeting held on the date hereof (the "Closing"), incident to the making of the 
initial Borrowing under the Credit Agreement. We have reviewed the forms of the 
Credit Agreement and the exhibits thereto and the opinion of Pillsbury Madison &
Sutro LLP, counsel to the Borrower and Guarantors (the "Opinion"). We have 
assumed the genuineness of all signatures, the authenticity of all documents 
submitted to us as originals or copies and the due authority of all persons 
executing the same, and we have relied as to factual matters on the documents 
which we have reviewed. We have further assumed, as to all actions that must be 
taken or conditions that must exist to any of the Agent's or the Bank's 
satisfaction, or as required by any of them under the terms of the Credit 
Agreement, including, without limitation, the form and substance of various 
agreements and other documents, that such actions have been taken and such 
conditions exist to such satisfaction or requirements, as the case may be.

       Although we have not independently considered any of the matters covered 
by the Opinion to the extent which would be necessary to enable us to express
the conclusions therein stated, we believe that the Opinion is substantially
responsive to the requirements of the Credit Agreement.

                            Very truly yours,

processing fee in the amount specified in Section 11.08(a) of the Credit

Agreement and not otherwise defined herein shall have the respective meanings
given to such terms in the Credit Agreement.  As used in this Guaranty, the

unconditionally guaranty, as primary obligors and not merely as sureties, the
due and punctual payment in full of all Guarantied Obligations when the same

     incurred or created, whether absolute or contingent, liquidated or
     unliquidated, whether due or not due, and however arising under or in
     connection with the Credit Agreement and the other Loan Documents,
     including those arising under successive borrowing transactions under the
     Credit Agreement which shall either continue such obligations of Company or
     from time to time renew them after they have been satisfied and including

     not a claim is allowed against Company for such interest in the related
     bankruptcy proceeding, and the obligation to make payments in the event of
     early termination thereunder; and

          (b) those expenses set forth in subsection 2.9 hereof.

Fraudulent Transfer Law (as hereinafter defined) is determined by a court of
competent jurisdiction to be applicable to the obligations of any Guarantor

or conveyance under Section 548 of Title 11 of the United States Code or any
applicable provisions of comparable state law (collectively, the "FRAUDULENT
TRANSFER LAWS"), in each case after giving 

                                      -3-
<PAGE>
 
effect to all other liabilities of such Guarantor, contingent or otherwise, that
are relevant under the Fraudulent Transfer Laws (specifically excluding,
however, any liabilities of such Guarantor (x) in respect of intercompany
indebtedness to Company or other affiliates of Company to the extent that such
indebtedness would be discharged in an amount equal to the amount paid by such
Guarantor hereunder and (y) under any guaranty of Subordinated Indebtedness
which guaranty contains a limitation as to maximum amount similar to that set
forth in this subsection 2.2(a), pursuant to which the liability of such
Guarantor hereunder is included in the liabilities taken into account in
determining such maximum amount) and after giving effect as assets to the value
(as determined under the applicable provisions of the Fraudulent Transfer Laws)
of any rights to subrogation, reimbursement, indemnification or contribution of
such Guarantor pursuant to applicable law or pursuant to the terms of any
agreement (including without limitation any such right of contribution under
subsection 2.2(b)).

     (b) Guarantors under this Guaranty together desire to allocate among
themselves, in a fair and equitable manner, their obligations arising under this
Guaranty.  Accordingly, in the event any payment or distribution is made on any
date by any Guarantor under this Guaranty (a "FUNDING GUARANTOR") that exceeds
its Fair Share (as defined below) as of such date, that Funding Guarantor shall
be entitled to a contribution from each of the other Guarantors in the amount of
such other Guarantor's Fair Share Shortfall (as defined below) as of such date,
with the result that all such contributions will cause each Guarantor's
Aggregate Payments (as defined below) to equal its Fair Share as of such date.
"FAIR SHARE" means, with respect to a Guarantor as of any date of determination,
an amount equal to (i) the ratio of (x) the Adjusted Maximum Amount (as defined
below) with respect to such Guarantor to (y) the aggregate of the Adjusted
Maximum Amounts with respect to all Guarantors, multiplied by (ii) the aggregate
                                                ---------- --                   
amount paid or distributed on or before such date by all Funding Guarantors
under this Guaranty in respect of the obligations guarantied.  "FAIR SHARE
SHORTFALL" means, with respect to a Guarantor as of any date of determination,
the excess, if any, of the Fair Share of such Guarantor over the Aggregate
Payments of such Guarantor.  "ADJUSTED MAXIMUM AMOUNT" means, with respect to a
Guarantor as of any date of determination, the maximum aggregate amount of the
obligations of such Guarantor under this Guaranty, determined as of such date in
accordance with subsection 2.2(a); provided that, solely for purposes of
                                   --------                             
calculating the "ADJUSTED MAXIMUM AMOUNT" with respect to any Guarantor for
purposes of this subsection 2.2(b), any assets or liabilities of such Guarantor
arising by virtue of any rights to subrogation, reimbursement or indemnification
or any rights to or obligations of contribution hereunder shall not be
considered as assets or liabilities of such Guarantor. "AGGREGATE PAYMENTS"
means, with respect to a Guarantor as of any date of determination, an amount
equal to (i) the aggregate amount of all payments and distributions made on or
before such date by such Guarantor in respect of this Guaranty (including,
without limitation, in respect of this subsection 2.2(b)) minus (ii) the
                                                          -----         
aggregate amount of all payments received on or before such date by such
Guarantor 

                                      -4-
<PAGE>
 
from the other Guarantors as contributions under this subsection 2.2(b). The
amounts payable as contributions hereunder shall be determined as of the date on
which the related payment or distribution is made by the applicable Funding
Guarantor. The allocation among Guarantors of their obligations as set forth in
this subsection 2.2(b) shall not be construed in any way to limit the liability
of any Guarantor hereunder.

     2.3  PAYMENT BY GUARANTORS; APPLICATION OF PAYMENTS.  Subject to the
          ----------------------------------------------                 
provisions of subsection 2.2(a), Guarantors hereby jointly and severally agree,
in furtherance of the foregoing and not in limitation of any other right which
Agent or any Bank may have at law or in equity against any Guarantor by virtue
hereof, that upon the failure of Company to pay any of the Guarantied
Obligations when and as the same shall become due, whether at stated maturity,
by required prepayment, declaration, acceleration, demand or otherwise
(including amounts that would become due but for the operation of the automatic
stay under Section 362(a) of the Bankruptcy Code, 11 U.S.C. (S) 362(a)),
Guarantors will upon demand pay, or cause to be paid, in cash, to Agent for the
ratable benefit of Banks, an amount equal to the sum of the unpaid principal
amount of all Guarantied Obligations then due as aforesaid, accrued and unpaid
interest on such Guarantied Obligations (including, without limitation, interest
which, but for the filing of a petition in bankruptcy with respect to Company,
would have accrued on such Guarantied Obligations, whether or not a claim is
allowed against Company for such interest in the related bankruptcy proceeding)
and all other Guarantied Obligations then owed to Banks and/or Agent as
aforesaid.  All such payments shall be applied promptly from time to time by
Agent:

          First, to the payment of costs and expenses of any collection or other
          -----                                                                 
     realization under this Guaranty, including reasonable compensation to Agent
     and its agents and counsel, and all expenses, liabilities and advances made
     or incurred by Agent in connection therewith;

          Second, to the payment of all other Guarantied Obligations; and
          ------                                                         

          Third, after payment in full of all Guarantied Obligations, to the
          -----                                                             
     payment to Guarantor, or its successors or assigns, or to whomsoever may be
     lawfully entitled to receive the same or as a court of competent
     jurisdiction may direct, of any surplus then remaining from such payments.

     2.4  LIABILITY OF GUARANTORS ABSOLUTE.  Each Guarantor agrees that its
          --------------------------------                                 
obligations hereunder are irrevocable, absolute, independent and unconditional
and shall not be affected by any circumstance which constitutes a legal or
equitable discharge of a guarantor or surety other than payment in full of the
Guarantied Obligations.  In furtherance of the foregoing and without limiting
the generality thereof, each Guarantor agrees as follows:

                                      -5-
<PAGE>
 
          (a) This Guaranty is a guaranty of payment when due and not of
     collectibility.

          (b) Agent may enforce this Guaranty upon the occurrence of an Event of
     Default under the Credit Agreement notwithstanding the existence of any
     dispute between Company and any Bank with respect to the existence of such
     Event of Default.

          (c) The obligations of each Guarantor hereunder are independent of the
     obligations of Company under the Credit Agreement and the obligations of
     any other guarantor (including any other Guarantor) of the obligations of
     Company under the Credit Agreement, and a separate action or actions may be
     brought and prosecuted against such Guarantor whether or not any action is
     brought against Company or any of such other guarantors and whether or not
     Company is joined in any such action or actions.

          (d) Payment by any Guarantor of a portion, but not all, of the
     Guarantied Obligations shall in no way limit, affect, modify or abridge any
     Guarantor's liability for any portion of the Guarantied Obligations which
     has not been paid.  Without limiting the generality of the foregoing, if
     Agent is awarded a judgment in any suit brought to enforce any Guarantor's
     covenant to pay a portion of the Guarantied Obligations, such judgment
     shall not be deemed to release such Guarantor from its covenant to pay the
     portion of the Guarantied Obligations that is not the subject of such suit,
     and such judgment shall not, except to the extent satisfied by such
     Guarantor, limit, affect, modify or abridge any other Guarantor's liability
     hereunder in respect of the Guarantied Obligations.

          (e) Any Bank, upon such terms as it deems appropriate, without notice
     or demand and without affecting the validity or enforceability of this
     Guaranty or giving rise to any reduction, limitation, impairment, discharge
     or termination of any Guarantor's liability hereunder, from time to time
     may (i) renew, extend, accelerate, increase the rate of interest on, or
     otherwise change the time, place, manner or terms of payment of the
     Guarantied Obligations, (ii) settle, compromise, release or discharge, or
     accept or refuse any offer of performance with respect to, or substitutions
     for, the Guarantied Obligations or any agreement relating thereto and/or
     subordinate the payment of the same to the payment of any other
     obligations; (iii) request and accept other guaranties of the Guarantied
     Obligations and take and hold security for the payment of this Guaranty or
     the Guarantied Obligations; (iv) release, surrender, exchange, substitute,
     compromise, settle, rescind, waive, alter, subordinate or modify, with or
     without consideration, any security for payment of the Guarantied
     Obligations, any other guaranties of the Guarantied Obligations, or any
     other 

                                      -6-
<PAGE>
 
     obligation of any Person (including any other Guarantor) with respect to
     the Guarantied Obligations; (v) enforce and apply any security now or
     hereafter held by or for the benefit of such Bank in respect of this
     Guaranty or the Guarantied Obligations and direct the order or manner of
     sale thereof, or exercise any other right or remedy that such Bank may have
     against any such security, in each case as such Bank in its discretion may
     determine consistent with the Credit Agreement and any applicable security
     agreement, including foreclosure on any such security pursuant to one or
     more judicial or nonjudicial sales, whether or not every aspect of any such
     sale is commercially reasonable, and even though such action operates to
     impair or extinguish any right of reimbursement or subrogation or other
     right or remedy of any Guarantor against Company or any security for the
     Guarantied Obligations; and (vi) exercise any other rights available to it
     under the Credit Agreement.

          (f) This Guaranty and the obligations of Guarantors hereunder shall be
     valid and enforceable and shall not be subject to any reduction,
     limitation, impairment, discharge or termination for any reason (other than
     payment in full of the Guarantied Obligations), including without
     limitation the occurrence of any of the following, whether or not any
     Guarantor shall have had notice or knowledge of any of them: (i) any
     failure or omission to assert or enforce or agreement or election not to
     assert or enforce, or the stay or enjoining, by order of court, by
     operation of law or otherwise, of the exercise or enforcement of, any claim
     or demand or any right, power or remedy (whether arising under the Credit
     Agreement, at law, in equity or otherwise) with respect to the Guarantied
     Obligations or any agreement relating thereto, or with respect to any other
     guaranty of or security for the payment of the Guarantied Obligations; (ii)
     any rescission, waiver, amendment or modification of, or any consent to
     departure from, any of the terms or provisions (including without
     limitation provisions relating to events of default) of the Credit
     Agreement or any agreement or instrument executed pursuant thereto, or of
     any other guaranty or security for the Guarantied Obligations, in each case
     whether or not in accordance with the terms of the Credit Agreement or any
     agreement relating to such other guaranty or security; (iii) the Guarantied
     Obligations, or any agreement relating thereto, at any time being found to
     be illegal, invalid or unenforceable in any respect; (iv) the application
     of payments received from any source (other than payments received pursuant
     to the Credit Agreement or from the proceeds of any security for the
     Guarantied Obligations, except to the extent such security also serves as
     collateral for indebtedness other than the Guarantied Obligations) to the
     payment of indebtedness other than the Guarantied Obligations, even though
     Agent or any Bank might have elected to apply such payment to any part or
     all of the Guarantied Obligations; (v) any Bank's consent to the change,
     reorganization or termination of the corporate structure or existence of
     Company or the corporate, partnership or limited liability company
     structure of 

                                      -7-
<PAGE>
 
     any of its Subsidiaries and to any corresponding restructuring of the
     Guarantied Obligations; (vi) any failure to perfect or continue perfection
     of a security interest in any collateral which secures any of the
     Guarantied Obligations; (vii) any defenses, set-offs or counterclaims which
     Company may allege or assert against any Bank in respect of the Guarantied
     Obligations, including but not limited to failure of consideration, breach
     of warranty, payment, statute of frauds, statute of limitations, accord and
     satisfaction and usury; and (viii) any other act or thing or omission, or
     delay to do any other act or thing, which may or might in any manner or to
     any extent vary the risk of any Guarantor as an obligor in respect of the
     Guarantied Obligations.

     2.5  WAIVERS BY GUARANTORS.  Each Guarantor hereby waives, for the benefit
          ---------------------                                                
of Banks and Agent:

          (a) any right to require Agent or any Bank, as a condition of payment
     or performance by such Guarantor, to (i) proceed against Company, any other
     guarantor (including any other Guarantor) of the Guarantied Obligations or
     any other Person, (ii) proceed against or exhaust any security held from
     Company, any such other guarantor (including any other Guarantor) or any
     other Person, (iii) proceed against or have resort to any balance of any
     deposit account or credit on the books of Agent or any Bank in favor of
     Company or any other Person, or (iv) pursue any other remedy in the power
     of Agent or any Bank whatsoever;

          (b) any defense arising by reason of the incapacity, lack of authority
     or any disability or other defense of Company including, without
     limitation, any defense based on or arising out of the lack of validity or
     the unenforceability of the Guarantied Obligations or any agreement or
     instrument relating thereto or by reason of the cessation of the liability
     of Company from any cause other than payment in full of the Guarantied
     Obligations;

          (c) any defense based upon any statute or rule of law which provides
     that the obligation of a surety must be neither larger in amount nor in
     other respects more burdensome than that of the principal;

          (d) any defense based upon Agent's or any Bank's errors or omissions
     in the administration of the Guarantied Obligations, except behavior which
     amounts to bad faith;

          (e) (i) any principles or provisions of law, statutory or otherwise,
     which are or might be in conflict with the terms of this Guaranty and any
     legal or equitable discharge of such Guarantor's obligations hereunder,
     (ii) the benefit of any statute of limitations affecting such Guarantor's
     liability hereunder or the 

                                      -8-
<PAGE>
 
     enforcement hereof, (iii) any rights to set-offs, recoupments and
     counterclaims, and (iv) promptness, diligence and any requirement that
     Agent or any Bank protect, secure, perfect or insure any security interest
     or lien or any property subject thereto;

          (f) notices, demands, presentments, protests, notices of protest,
     notices of dishonor and notices of any action or inaction, including
     acceptance of this Guaranty, notices of default under the Credit Agreement,
     the Loan Documents or any agreement or instrument related thereto, notices
     of any renewal, extension or modification of the Guarantied Obligations or
     any agreement related thereto, notices of any extension of credit to
     Company and notices of any of the matters referred to in subsection 2.4 and
     any right to consent to any thereof; and

          (g) any defenses or benefits that may be derived from or afforded by
     law which limit the liability of or exonerate guarantors or sureties, or
     which may conflict with the terms of this Guaranty.

     2.6  CERTAIN CALIFORNIA LAW WAIVERS.  As used in this subsection 2.6, any
          ------------------------------                                      
reference to "the principal" includes Company, and any reference to "the
creditor" includes Agent and each Bank.  In accordance with Section 2856 of the
California Civil Code:

          (a) each Guarantor agrees (i) to waive any and all rights of
     subrogation and reimbursement against Company or against any collateral or
     security granted by Company for any of the Guarantied Obligations and (ii)
     to withhold the exercise of any and all rights of subrogation,
     reimbursement and contribution against Company, against any other guarantor
     of any of the Guarantied Obligations and against any collateral or security
     granted by any such other guarantor for any of the Guarantied Obligations
     until the Guarantied Obligations shall have been paid in full and all
     letters of credit issued under the Credit Agreement and the other Loan
     Documents shall have expired or been cancelled, all as more fully set forth
     in subsection 2.7;

          (b) each Guarantor waives any and all other rights and defenses
     available to such Guarantor by reason of Sections 2787 to 2855, inclusive,
     2899 and 3433 of the California Civil Code, including without limitation
     any and all rights or defenses such Guarantor may have by reason of
     protection afforded to the principal with respect to any of the Guarantied
     Obligations, or to any other guarantor (including any other Guarantor) of
     any of the Guarantied Obligations with respect to any of such guarantor's
     obligations under its guaranty, in either case pursuant to the
     antideficiency or other laws of the State of California limiting or
     discharging the principal's indebtedness or such guarantor's 

                                      -9-
<PAGE>
 
     obligations, including without limitation Section 580a, 580b, 580d, or 726
     of the California Code of Civil Procedure; and

          (c) each Guarantor waives all rights and defenses arising out of an
     election of remedies by the creditor, even though that election of
     remedies, such as a nonjudicial foreclosure with respect to security for
     any Guarantied Obligation, has destroyed such Guarantor's rights of
     subrogation and reimbursement against the principal by the operation of
     Section 580d of the Code of Civil Procedure or otherwise; and even though
     that election of remedies by the creditor, such as nonjudicial foreclosure
     with respect to security for an obligation of any other guarantor
     (including any other Guarantor) of any of the Guarantied Obligations, has
     destroyed such Guarantor's rights of contribution against such other
     guarantor.

No other provision of this Guaranty shall be construed as limiting the
generality of any of the covenants and waivers set forth in this subsection 2.6.

     2.7  GUARANTORS' RIGHTS OF SUBROGATION, CONTRIBUTION, ETC.  Each Guarantor
          ----------------------------------------------------                 
hereby waives any claim, right or remedy, direct or indirect, that such
Guarantor now has or may hereafter have against Company or any of its assets in
connection with this Guaranty or the performance by such Guarantor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute (including without limitation under
California Civil Code Section 2847, 2848 or 2849), under common law or otherwise
and including without limitation (a) any right of subrogation, reimbursement or
indemnification that such Guarantor now has or may hereafter have against
Company, (b) any right to enforce, or to participate in, any claim, right or
remedy that Agent or any Bank now has or may hereafter have against Company, and
(c) any benefit of, and any right to participate in, any collateral or security
now or hereafter held by Agent or any Bank.  In addition, until the Guarantied
Obligations shall have been indefeasibly paid in full and all letters of credit
issued under the Credit Agreement shall have expired or been cancelled, each
Guarantor shall withhold exercise of any right of contribution such Guarantor
may have against any other guarantor (including any other Guarantor) of the
Guarantied Obligations (including without limitation any such right of
contribution under California Civil Code Section 2848 or under subsection
2.2(b)).  Each Guarantor further agrees that, to the extent the waiver or
agreement to withhold the exercise of its rights of subrogation, reimbursement,
indemnification and contribution as set forth herein is found by a court of
competent jurisdiction to be void or voidable for any reason, any rights of
subrogation, reimbursement or indemnification such Guarantor may have against
Company or against any collateral or security, and any rights of contribution
such Guarantor may have against any such other guarantor, shall be junior and
subordinate to any rights Agent or any Bank may have against Company, to all
right, title and interest Agent or any Bank may have in any such collateral or
security, 

                                      -10-
<PAGE>
 
and to any right Agent or any Bank may have against such other guarantor. If any
amount shall be paid to any Guarantor on account of any such subrogation,
reimbursement, indemnification or contribution rights at any time when all
Guarantied Obligations shall not have been paid in full, such amount shall be
held in trust for Agent on behalf of Banks and shall forthwith be paid over to
Agent for the benefit of Banks to be credited and applied against the Guarantied
Obligations, whether matured or unmatured, in accordance with the terms hereof.

     2.8  SUBORDINATION OF OTHER OBLIGATIONS.  Any indebtedness of Company now
          ----------------------------------                                  
or hereafter held by any Guarantor is hereby subordinated in right of payment to
the Guarantied Obligations, and any such indebtedness of Company to such
Guarantor collected or received by such Guarantor after an Event of Default has
occurred and is continuing shall be held in trust for Agent on behalf of Banks
and shall forthwith be paid over to Agent for the benefit of Banks to be
credited and applied against the Guarantied Obligations but without affecting,
impairing or limiting in any manner the liability of such Guarantor under any
other provision of this Guaranty.

     2.9  EXPENSES.  Guarantors jointly and severally agree to pay, or cause to
          --------                                                             
be paid, on demand, and to save Agent and Banks harmless against liability for,
any and all costs and expenses (including fees and disbursements of counsel and
allocated costs of internal counsel) incurred or expended by Agent or any Bank
in connection with the enforcement of or preservation of any rights under this
Guaranty.

     2.10 CONTINUING GUARANTY.  This Guaranty is a continuing guaranty and shall
          -------------------                                                   
remain in effect until all of the Guarantied Obligations shall have been paid in
full and all letters of credit issued under the Credit Agreement shall have
expired or been cancelled.  Each Guarantor hereby irrevocably waives any right
(including without limitation any such right arising under California Civil Code
Section 2815) to revoke this Guaranty as to future transactions giving rise to
any Guarantied Obligations.

     2.11 AUTHORITY OF GUARANTORS OR COMPANY.  It is not necessary for Agent or
          ----------------------------------                                   
any Bank to inquire into the capacity or powers of any Guarantor or Company or
the officers, directors or any agents acting or purporting to act on behalf of
any of them.

     2.12 FINANCIAL CONDITION OF COMPANY.  Any Loans may be granted to Company
          ------------------------------                                      
or continued from time to time without notice to or authorization from any
Guarantor regardless of the financial or other condition of Company at the time
of any such grant or continuation.  Agent and Banks shall have no obligation to
disclose or discuss with any Guarantor its assessment, or any Guarantor's
assessment, of the financial condition of Company.  Each Guarantor has adequate
means to obtain information from Company on a continuing basis concerning the
financial condition of Company and its ability to perform its obligations under
the Credit Agreement, and each Guarantor assumes the responsibility for being
and keeping informed of the 

                                      -11-
<PAGE>
 
financial condition of Company and of all circumstances bearing upon the risk of
nonpayment of the Guarantied Obligations. Each Guarantor hereby waives and
relinquishes any duty on the part of Agent or any Bank to disclose any matter,
fact or thing relating to the business, operations or conditions of Company now
known or hereafter known by Agent or any Bank.

     2.13 RIGHTS CUMULATIVE.  The rights, powers and remedies given to Banks and
          -----------------                                                     
Agent by this Guaranty are cumulative and shall be in addition to and
independent of all rights, powers and remedies given to Banks and Agent by
virtue of any statute or rule of law or in the Credit Agreement any other Loan
Document or any agreement between any Guarantor and Agent and/or any Bank or
between Company and any Agent and/or any Bank.  Any forbearance or failure to
exercise, and any delay by Agent or any Bank in exercising, any right, power or
remedy hereunder shall not impair any such right, power or remedy or be
construed to be a waiver thereof, nor shall it preclude the further exercise of
any such right, power or remedy.

     2.14 BANKRUPTCY: POST-PETITION INTEREST: REINSTATEMENT OF GUARANTY.  (a) So
          -------------------------------------------------------------         
long as any Guarantied Obligations remain outstanding, no Guarantor shall,
without the prior written consent of Agent, commence or join with any other
Person in commencing any bankruptcy, reorganization or insolvency proceedings of
or against Company.  The obligations of Guarantors under this Guaranty shall not
be reduced, limited, impaired, discharged, deferred, suspended or terminated by
any proceeding, voluntary or involuntary, involving the bankruptcy, insolvency,
receivership, reorganization, liquidation or arrangement of Company or by any
defense which Company may have by reason of the order, decree or decision of any
court or administrative body resulting from any such proceeding.

     (b) Each Guarantor acknowledges and agrees that any interest on any portion
of the Guarantied Obligations which accrues after the commencement of any
proceeding referred to in clause (a) above (or, if interest on any portion of
the Guarantied Obligations ceases to accrue by operation of law by reason of the
commencement of said proceeding, such interest as would have accrued on such
portion of the Guarantied Obligations if said proceedings had not been
commenced) shall be included in the Guarantied Obligations because it is the
intention of Guarantors, Agent and Banks that the Guarantied Obligations which
are guarantied by Guarantors pursuant to this Guaranty should be determined
without regard to any rule of law or order which may relieve Company of any
portion of such Guarantied Obligations.  Guarantors will permit any trustee in
bankruptcy, receiver, debtor in possession, assignee for the benefit of
creditors or similar person to pay Agent, or allow the claim of Agent in respect
of, any such interest accruing after the date on which such proceeding is
commenced.

                                      -12-
<PAGE>
 
     (c) In the event that all or any portion of the Guarantied Obligations are
paid by Company, the obligations of Guarantors hereunder shall continue and
remain in full force and effect or be reinstated, as the case may be, in the
event that all or any part of such payment(s) are rescinded or recovered
directly or indirectly from Agent or any Bank as a preference, fraudulent
transfer or otherwise, and any such payments which are so rescinded or recovered
shall constitute Guarantied Obligations for all purposes under this Guaranty.

     2.15 NOTICE OF EVENTS.  As soon as any Guarantor obtains knowledge thereof,
          ----------------                                                      
such Guarantor shall give Agent written notice of any condition or event which
has resulted in (a) a material adverse change in the financial condition of any
Guarantor or Company or (b) a breach of or noncompliance with any term,
condition or covenant contained herein or in the Credit Agreement, any other
Loan Document or any other document delivered pursuant hereto or thereto.

     2.16 SET OFF.  In addition to any other rights Agent or any Bank may have
          -------                                                             
under law or in equity, if any amount shall at any time be due and owing by any
Guarantor to Agent or any Bank under this Guaranty, such Bank or Agent is
authorized at any time or from time to time, without notice (any such notice
being hereby expressly waived), to set off and to appropriate and to apply any
and all property of such Guarantor held by Agent or any Bank to or for the
credit or the account of such Guarantor against and on account of the Guarantied
Obligations and liabilities of such Guarantor to Agent or any Bank under this
Guaranty.

SECTION 3. REPRESENTATIONS AND WARRANTIES.

     In order to induce the Banks and the Agent to accept this Guaranty and to
enter into the Credit Agreement and make the Loans thereunder, each Guarantor
hereby represents and warrants to Agent and each Bank that the following
statements are true and correct:

     3.1  EXISTENCE.  Such Guarantor is duly organized, validly existing and in
          ---------                                                            
good standing under the laws of the state of its incorporation or formation, has
the power to own its assets and to transact the business in which it is now
engaged and is duly qualified as a foreign corporation, partnership or limited
liability company and in good standing under the laws of each jurisdiction where
its ownership or lease of property or the conduct of its business requires such
qualification, except for failures to be so qualified, authorized or licensed
that would not in the aggregate have a material adverse effect on the business,
operations, assets or financial condition of such Guarantor and its
Subsidiaries, taken as a whole.

     3.2  POWER: AUTHORIZATION: ENFORCEABLE OBLIGATIONS.  Such Guarantor has the
          ---------------------------------------------                         
power, authority and legal right to execute, deliver and perform this Guaranty
and 

                                      -13-
<PAGE>
 
all obligations required hereunder and has taken all necessary action to
authorize its Guaranty hereunder on the terms and conditions hereof and its
execution, delivery and performance of this Guaranty and all obligations
required hereunder. No consent of any other Person including, without
limitation, stockholders, members, partners and/or creditors of such Guarantor,
and no license, permit, approval or authorization of, exemption by, notice or
report to, or registration, filing or declaration with, any governmental
authority is required by such Guarantor in connection with this Guaranty or the
execution, delivery, performance, validity or enforceability of this Guaranty
and all obligations required hereunder. This Guaranty has been, and each
instrument or document required hereunder will be, executed and delivered by a
duly authorized officer of such Guarantor, and this Guaranty constitutes, and
each instrument or document required hereunder when executed and delivered by
such Guarantor hereunder will constitute, the legally valid and binding
obligation of such Guarantor, enforceable against such Guarantor in accordance
with its terms, except as enforcement may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws or equitable
principles relating to or limiting creditors' rights generally.

     3.3  NO LEGAL BAR TO THIS GUARANTY.  The execution, delivery and
          -----------------------------                              
performance of this Guaranty and the documents or instruments required
hereunder, and the use of the proceeds of Loans under the Credit Agreement, will
not violate any provision of any existing law or regulation binding on such
Guarantor, or any order, judgment, award or decree of any court, arbitrator or
governmental authority binding on such Guarantor, or the certificate of
incorporation or bylaws, or certificate of partnership or partnership agreement,
or articles of organization or operating agreement, of such Guarantor or any
securities issued by such Guarantor, or any mortgage, indenture, lease, contract
or other agreement, instrument or undertaking to which such Guarantor is a party
or by which such Guarantor or any of its assets may be bound, the violation of
which would have a material adverse effect on the business, operations, assets
or financial condition of such Guarantor and will not result in, or require, the
creation or imposition of any Lien on any of its property, assets or revenues
pursuant to the provisions of any such mortgage, indenture, lease, contract or
other agreement, instrument or undertaking.

SECTION 4. AFFIRMATIVE COVENANTS

     Each Guarantor covenants and agrees that, unless and until all of the
Guarantied Obligations shall have been paid in full, unless the Required Banks

material respects with all applicable laws, rules, regulations and orders, such
compliance to include, without limitation, paying when due all taxes,
assessments and governmental charges imposed upon it or upon any of its
properties or assets or in respect of any of its franchises, businesses, income
or property before any penalty or interest accrues thereon.

     4.3  BOOKS AND RECORDS.  Such Guarantor shall keep and maintain books of
          -----------------                                                  
record and account with respect to its operations in accordance with generally
accepted accounting principles and shall permit Agent or any Bank and their
officers, employees and authorized agents, to the extent Agent in good faith
deems necessary for the proper administration of this Guaranty, to examine, copy

of any and all disputes that may be filed in any court and that relate to the
subject matter of this transaction, including without limitation contract
claims, tort claims, breach of duty claims and all other common law and
statutory claims.  Each Guarantor and, by its acceptance of the benefits hereof,
Agent and each lender, each (i) acknowledges that this waiver is a material
inducement for such Guarantor and Agent and each Bank, to enter into a business
relationship, that such Guarantor and Agent and each Bank, have already relied

modify any terms of this Guaranty.  There are no conditions to the full
effectiveness of this Guaranty.

     5.11 FURTHER ASSURANCES.  At any time or from time to time, upon the
          ------------------                                             
request of Agent or Required Banks, Guarantors shall execute and deliver such
further documents and do such other acts and things as Agent or Required Banks
may reasonably request in order to effect fully the purposes of this Guaranty.

of the Material Subsidiaries of Company as are signatories hereto on the date
hereof. From time to time subsequent to the date hereof, additional Material
Subsidiaries of Company may become parties hereto, as additional Guarantors
(each an "ADDITIONAL GUARANTOR"), by executing a counterpart of this Guaranty.
Upon delivery of any such counterpart to Agent, notice of which is hereby waived
by Guarantors, each such Additional Guarantor shall be a Guarantor and shall be
as fully a party hereto as if such Additional Guarantor were an original
signatory hereof.  Each Guarantor expressly agrees that its obligations arising
hereunder shall not be affected or diminished by the addition or release of any
other Guarantor hereunder, nor by any election of Agent or Required Banks not to
cause any Material Subsidiary of Company to become an Additional Guarantor
hereunder.  This Guaranty shall be fully effective as to any Guarantor that is
or becomes a party hereto regardless of whether any other Person becomes or
fails to become or ceases to be a Guarantor hereunder.

     5.13 COUNTERPARTS: EFFECTIVENESS.  This Guaranty may be executed in any
          ---------------------------                                       
number of counterparts and by the different parties hereto in separate
counterparts, each of which when so executed and delivered shall be deemed to be
an original for all purposes; but all such counterparts together shall
constitute but one and the same instrument.  This Guaranty shall become
effective as to each Guarantor upon the execution of a counterpart hereof by
such Guarantor (whether or not a counterpart hereof shall have been executed by
any other Guarantor) and receipt by Agent of written or telephonic notification
of such execution and authorization of delivery thereof.

          SECTION 1.  PLEDGE AND GRANT OF SECURITY INTERESTS.  Pledgor hereby
                      --------------------------------------

any or all of the Pledged Shares;

          (b) all additional shares of, and all securities convertible into and

certificates or other instruments representing such additional shares,
securities, warrants, options or other rights and any interest of Pledgor in the
entries on the books of any securities intermediary pertaining to such
additional shares, securities, warrants, options or other rights, and all
dividends, cash, warrants, rights, instruments and other property or proceeds
from time to time received, receivable or otherwise distributed in respect of or

rights and any interest of Pledgor in the entries on the books of any securities
intermediary pertaining to such shares, securities, warrants, options or other

liabilities of every nature of Pledgor now or hereafter existing under or
arising out of or in connection with the Credit Agreement, the Guaranty and the

filing of a petition in bankruptcy with respect to Pledgor, would accrue on such
obligations), fees, expenses, indemnities or otherwise, whether voluntary or
involuntary, direct or indirect, absolute or contingent, liquidated or
unliquidated, determined or undetermined, whether or not jointly owed with
others, and whether or not from time to time decreased or extinguished and later

preference, fraudulent transfer or otherwise (all such obligations and
liabilities being the "UNDERLYING DEBT"), and all obligations of every nature of
Pledgor now or hereafter existing under this Agreement and under any other Loan

          SECTION 6.  FURTHER ASSURANCES; PLEDGE AMENDMENTS.
                      ------------------------------------- 

          (a) Pledgor agrees that from time to time, at the expense of Pledgor,
Pledgor will promptly execute and deliver all further instruments and documents,
and take all further action, that may be necessary or desirable, or that Agent
may request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable Agent to exercise and enforce its
rights and remedies hereunder with respect to any Pledged Collateral.  Without
limiting the generality of the foregoing, Pledgor will:  (i) execute and file
such financing or continuation statements, or amendments thereto, and such other
instruments or notices (including, without limitation, stock powers with respect
to, or other endorsements or instruments necessary to effect the assignment or
other transfer of, any of the Pledged Collateral), as may be necessary or
desirable, or as Agent may request, in order to perfect and preserve the
security interests granted or purported to be granted hereby and (ii) at Agent's
request, appear in and defend any action or proceeding that may affect Pledgor's
title to or Agent's security interest in all or any part of the Pledged
Collateral.

          (b) Pledgor further agrees that it will, upon obtaining any additional
shares of stock or other securities required to be pledged hereunder as provided
in Section 5(b), promptly (and in any event within five Business Days) deliver
to Agent a Pledge Amendment, duly executed by Pledgor, in substantially the form
of Schedule IV annexed hereto (a "PLEDGE AMENDMENT"), in respect of the
   -----------                                                         
additional Pledged Shares to be pledged pursuant to this Agreement.  Pledgor
hereby authorizes Agent to attach each Pledge Amendment to this Agreement and
agrees that all Pledged Shares listed on any Pledge Amendment delivered to Agent
shall for all purposes hereunder be considered Pledged Collateral; provided,

impair the security interest of Agent therein or otherwise adversely affect the
rights and remedies of Agent hereunder with respect thereto.

              (i)   Pledgor shall be entitled to exercise any and all voting and
other consensual rights pertaining to the Pledged Collateral or any part thereof
for any purpose not inconsistent with the terms of this Agreement or the Credit
Agreement; provided, however, that Pledgor shall not exercise or refrain from

judgment, such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof;

              (ii)  Pledgor shall be entitled to receive and retain, and to
utilize free and clear of the lien of this Agreement, any and all dividends and
interest paid in respect of the Pledged Collateral; provided, however, that any
                                                    --------  -------

Collateral and shall, if received by Pledgor, be received in trust for the
benefit of Agent, be segregated from the other property or funds of Pledgor and
be forthwith delivered to Agent as Pledged Collateral in the same form as so
received (with all necessary endorsements); and

              (iii) Agent shall promptly execute and deliver (or cause to be
executed and delivered) to Pledgor all such proxies, dividend payment orders and
other instruments as Pledgor may from time to time reasonably request for the
purpose of enabling Pledgor to exercise the voting and other consensual rights
which it is entitled to exercise pursuant to paragraph (i) above and to receive
the dividends, principal or interest payments which it is authorized to receive
and retain pursuant to paragraph (ii) above.

          (b) Upon the occurrence and during the continuation of any Default or
Event of Default:

              (i)   upon written notice from Agent to Pledgor, all rights of

otherwise be 

                                      -7-

entitled to exercise pursuant to Section 7(a)(i) shall cease, and all such
rights shall thereupon become vested in Agent who shall thereupon have the sole
right to exercise such voting and other consensual rights;

              (ii)  all rights of Pledgor to receive the dividends and interest
payments which it would otherwise be authorized to receive and retain pursuant
to Section 7(a)(ii) shall cease, and all such rights shall thereupon become
vested in Agent who shall thereupon have the sole right to receive and hold as
Pledged Collateral such dividends and interest payments; and

              (iii) all dividends, principal and interest payments which are
received by Pledgor contrary to the provisions of paragraph (ii) of this Section
7(b) shall be received in trust for the benefit of Agent, shall be segregated
from other funds of Pledgor and shall forthwith be paid over to Agent as Pledged
Collateral in the same form as so received (with any necessary endorsements).

          (c) In order to permit Agent to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section
7(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Agent all such proxies, dividend payment orders and other instruments as Agent
may from time to time reasonably request and (ii) without limiting the effect of
the immediately preceding clause (i), Pledgor hereby grants to Agent an
irrevocable proxy to vote the Pledged Collateral and to exercise all other
rights, powers, privileges and remedies to which a holder of the Pledged
Collateral would be entitled (including, without limitation, giving or
withholding written consents of shareholders, calling special meetings of
shareholders and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Collateral on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Collateral or any officer or agent
thereof), upon the occurrence of an Event of Default or Default and which proxy
shall only terminate upon the payment in full of the Secured Obligations.

          SECTION 8.  AGENT APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby
                      --------------------------------                 
irrevocably appoints Agent as Pledgor's attorney-in-fact, with full authority in
the place and stead of Pledgor and in the name of Pledgor, Agent or otherwise,
from time to time in Agent's discretion to take any action and to execute any
instrument that Agent may deem necessary or advisable to accomplish the purposes
of this Agreement, including without limitation:

          (a) to file one or more financing or continuation statements, or
amendments thereto, or stock powers or other endorsements or instruments of
transfer or assignments in blank, relative to all or any part of the Pledged
Collateral, or to enter 

                                      -8-
<PAGE>
 
into agreements with Agent and any securities intermediaries described in
Section 1 relating to any Pledged Collateral to protect Agent's security
interest therein, in form and substance satisfactory to Agent, in each case
without the signature of Pledgor;

          (b) after the occurrence and during the continuation of any Event of
Default, to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Pledged Collateral;

          (c) after the occurrence and during the continuation of any Event of
Default, to receive, endorse and collect any instruments made payable to Pledgor
representing any dividend, principal or interest payment or other distribution
in respect of the Pledged Collateral or any part thereof and to give full
discharge for the same; and

          (d) after the occurrence and during the continuation of any Event of
Default, to file any claims or take any action or institute any proceedings that
Agent may deem necessary or desirable for the collection of any of the Pledged
Collateral or otherwise to enforce the rights of Agent with respect to any of
the Pledged Collateral.

          SECTION 9.  AGENT MAY PERFORM.  If Pledgor fails to perform any
                      -----------------                                  
agreement contained herein, Agent may itself perform, or cause performance of,
such agreement, and the expenses of Agent incurred in connection therewith shall
be payable by Pledgor under Section 12(b).

          SECTION 10.  STANDARD OF CARE.  The powers conferred on Agent
                       ----------------                                
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Agent shall have no duty as to any Pledged Collateral, it being understood that
Agent shall have no responsibility for (a) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Pledged Collateral, whether or not Agent has or is deemed to
have knowledge of such matters, (b) taking any necessary steps (other than steps
taken in accordance with the standard of care set forth above to maintain
possession of the Pledged Collateral) to preserve rights against any parties
with respect to any Pledged Collateral, (c) taking any necessary steps to
collect or realize upon the Secured Obligations or any guarantee therefor, or
any part thereof, or any of the Pledged Collateral, or (d) initiating any action
to protect the Pledged Collateral against the possibility of a decline in market
value.  Agent shall be deemed to have exercised reasonable care in the custody
and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Agent accords
its own property consisting of negotiable securities.

          SECTION 11.  REMEDIES.
                       -------- 

          (a) If any Event of Default shall have occurred and be continuing,
Agent may, subject to the terms of the Credit Agreement, exercise in respect of
the Pledged Collateral, in addition to all other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party on default under the Uniform Commercial Code as in effect in any
relevant jurisdiction (the "CODE") (whether or not the Code applies to the
affected Pledged Collateral), and Agent may also in its sole discretion, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale, at any exchange or
broker's board or at any of Agent's offices or elsewhere, for cash, on credit or
for future delivery, at such time or times and at such price or prices and upon
such other terms as Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged Collateral.  Agent
or any Bank may be the purchaser of any or all of the Pledged Collateral at any
such sale and Agent, as agent for and representative of the Banks, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at any such
public sale, to use and apply any of the Secured Obligations as a credit on
account of the purchase price for any Pledged Collateral payable by Agent at
such sale.  Each purchaser at any such sale shall hold the property sold
absolutely free from any claim or right on the part of Pledgor, and Pledgor
hereby waives (to the extent permitted by applicable law) all rights of
redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.
Pledgor agrees that, to the extent notice of sale shall be required by law, at
least ten days' notice to Pledgor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification.  Agent shall not be obligated to make any sale of Pledged
Collateral regardless of notice of sale having been given. Agent may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned.  To the extent permitted by applicable
law, Pledgor hereby waives any claims against Agent arising by reason of the
fact that the price at which any Pledged Collateral may have been sold at any
such private sale was less than the price which might have been obtained at a
public sale, even if Agent accepts the first offer received and does not offer
such Pledged Collateral to more than one offeree.  If the proceeds of any sale
or other disposition of the Pledged Collateral are insufficient to pay all of
the Secured Obligations, Pledgor shall be liable for the deficiency and the
reasonable fees of any attorneys employed by Agent to collect such deficiency.

          (b) Any cash held by Agent as Pledged Collateral and all cash proceeds
received by Agent in respect of any sale of, collection from, or other
realization upon all or any part of the Pledged Collateral may, in the
discretion of 

                                      -10-
<PAGE>
 
Agent, be held by Agent as collateral for, and/or then or at any time thereafter
applied (after payment of any amounts payable to Agent pursuant to Section
12(b)) in whole or in part by Agent against all or any part of the Secured
Obligations in such order as Agent shall elect. Any surplus of such cash or cash
proceeds held by Agent and remaining after payment in full of all the Secured
Obligations shall be paid over to Pledgor or to whosoever may be lawfully
entitled to receive such surplus.

          (c) Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended from time to time (the
"SECURITIES ACT"), and applicable state securities laws, Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under the
Securities Act and/or such state securities laws, to conduct such sales as
private, not public, sales and to limit purchasers to a restricted group who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  Pledgor acknowledges and agrees that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering made
pursuant to an effective registration statement under the Securities Act) and,
notwithstanding such circumstances, Pledgor agrees that any such private sale
shall be conclusively deemed to have been made in a commercially reasonable
manner and that Agent shall have no obligation either to engage in public sales
or to delay the sale of any Pledged Collateral for the period of time necessary
to permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would, or should, agree to so register it.  Pledgor further
acknowledges the impossibility of ascertaining the amount of damages which would
be suffered by Agent by reason of the failure by Pledgor to perform any of the
covenants contained in this Section and, consequently, agrees that, if Pledgor
shall fail to perform any of such covenants, it shall pay, as liquidated damages
and not as a penalty, an amount equal to the value of the Pledged Collateral on
the date Agent shall demand compliance with this Section.

          (d) If Agent determines to exercise its right to sell any or all of
the Pledged Collateral, upon written request, Pledgor shall and shall cause each
issuer of any Pledged Shares to be sold hereunder from time to time to furnish
to Agent all such information as Agent may request in order to determine the
number of shares and other instruments included in the Pledged Collateral which
may be sold by Agent in exempt transactions under the Securities Act and the
rules and regulations of the Securities and Exchange Commission thereunder, as
the same are from time to time in effect.

          SECTION 12.  INDEMNITY AND EXPENSES.
                       ---------------------- 

          (a) Pledgor agrees to indemnify Agent and each Bank from and against
any and all claims, losses and liabilities in any way relating to, growing out
of or resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses or liabilities result solely from Agent's or such
Bank's gross negligence or willful misconduct as finally determined by a court
of competent jurisdiction.

          (b) Pledgor shall pay to Agent upon demand the amount of any and all
costs and expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, that Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Agent
hereunder, or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

          SECTION 13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
                       -----------------------------------------------      
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the payment in full of all
Secured Obligations, (b) be binding upon Pledgor, its successors and assigns,
and (c) inure, together with the rights and remedies of Agent hereunder, to the
benefit of Agent and its successors, transferees and assigns.  Without limiting
the generality of the foregoing clause (c), any Bank may, subject to the terms
of the Credit Agreement, assign or otherwise transfer its interest in the Credit
Agreement in whole or in part to any other Person, and such other Person shall
thereupon become vested with all benefits in respect thereof granted to Banks
herein or otherwise.  Upon the payment in full of all Secured Obligations, the
security interest granted hereby shall terminate and all rights to the Pledged
Collateral shall revert to Pledgor.  Upon any such termination Agent will, at
Pledgor's expense, execute and deliver to Pledgor such documents as Pledgor
shall reasonably request to evidence such termination and Pledgor shall be
entitled to the return, upon its request and at its expense, against receipt and
without recourse to Agent, of such of the Pledged Collateral as shall not have
been sold or otherwise applied pursuant to the terms hereof.

          SECTION 14.  AMENDMENTS; ETC.  Subject to Section 11.01 of the Credit
                       ---------------                                         
Agreement, no amendment, modification, termination or waiver of any provision of
this Agreement, and no consent to any departure by Pledgor therefrom, shall in
any event be effective unless the same shall be in writing and signed by Agent
and, in the case of any such amendment or modification, by Pledgor.  Any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which it was given.

either party, such other address as shall be designated by such party in a
written notice delivered to the other party hereto.

          SECTION 16.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                       -----------------------------------------------------  
No failure or delay on the part of Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 17.  SEVERABILITY.  In case any provision in or obligation
                       ------------                                         
under this Agreement shall be invalid, illegal or unenforceable in any
jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby.

used in Articles 8 and 9 of the UCC are used herein as therein defined.

receipt requested, to Pledgor at its address provided in Section 15, such
service being hereby acknowledged by Pledgor to be sufficient for personal
jurisdiction in any action against Pledgor in any such court and to be otherwise
effective and binding service in every respect.  Nothing herein shall affect the
right to serve process in any other manner permitted by law or shall limit the
right of Agent to bring proceedings against Pledgor in the courts of any other
jurisdiction.

          SECTION 21.  WAIVER OF JURY TRIAL.  PLEDGOR AND AGENT HEREBY AGREE TO
                       --------------------

intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach of duty claims, and all
other common law and statutory claims.  Pledgor and Agent each acknowledge that
this waiver is a material inducement for Pledgor and Agent to enter into a

in entering into this Agreement and that each will continue to rely on this
waiver in their related future dealings.  Pledgor and Agent further warrant and

each knowingly and voluntarily waives its jury trial rights following
consultation with legal counsel.  THIS WAIVER IS IRREVOCABLE, MEANING THAT IT

may request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable Agent to exercise and enforce its
rights and remedies hereunder with respect to any Pledged Collateral.  Without

hereby authorizes Agent to attach each Pledge Amendment to this Agreement and
agrees that all Pledged Shares listed on any Pledge Amendment delivered to Agent
shall for all purposes hereunder be considered Pledged Collateral; provided,
                                                                   --------

judgment, such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof;

received (with all necessary endorsements); and

         (iii)  Agent shall promptly execute and deliver (or cause to be
executed and delivered) to Pledgor all such proxies, dividend payment orders and
other instruments as Pledgor may from time to time reasonably request for the
purpose of enabling Pledgor to exercise the voting and other consensual rights
which it is entitled to exercise pursuant to paragraph (i) above and to receive
the dividends, principal or interest payments which it is authorized to receive
and retain pursuant to paragraph (ii) above.

                                      -7-

          (b) Upon the occurrence and during the continuation of any Default or
Event of Default:

              (i) upon written notice from Agent to Pledgor, all rights of
Pledgor to exercise the voting and other consensual rights which it would
otherwise be entitled to exercise pursuant to Section 7(a)(i) shall cease, and
all such rights shall thereupon become vested in Agent who shall thereupon have
the sole right to exercise such voting and other consensual rights;

             (ii) all rights of Pledgor to receive the dividends and interest
payments which it would otherwise be authorized to receive and retain pursuant
to Section 7(a)(ii) shall cease, and all such rights shall thereupon become
vested in Agent who shall thereupon have the sole right to receive and hold as
Pledged Collateral such dividends and interest payments; and

            (iii) all dividends, principal and interest payments which
are received by Pledgor contrary to the provisions of paragraph (ii) of this
Section 7(b) shall be received in trust for the benefit of Agent, shall be
segregated from other funds of Pledgor and shall forthwith be paid over to Agent
as Pledged Collateral in the same form as so received (with any necessary
endorsements).

       (c)  In order to permit Agent to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section
7(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Agent all such proxies, dividend payment orders and other instruments as Agent
may from time to time reasonably request and (ii) without limiting the effect of
the immediately preceding clause (i), Pledgor hereby grants to Agent an
irrevocable proxy to vote the Pledged Collateral and to exercise all other
rights, powers, privileges and remedies to which a holder of the Pledged
Collateral would be entitled (including, without limitation, giving or
withholding written consents of shareholders, calling special meetings of
shareholders and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Collateral on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Collateral or any officer or agent
thereof), upon the occurrence of an Event of Default or Default and which proxy
shall only terminate upon the payment in full of the Secured Obligations.

          SECTION 8.  AGENT APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby
                      --------------------------------                 
irrevocably appoints Agent as Pledgor's attorney-in-fact, with full authority in
the place and stead of Pledgor and in the name of Pledgor, Agent or otherwise,
from time to time in Agent's discretion to take any action and to execute any
instrument that Agent may

                                      -8-
<PAGE>
 
deem necessary or advisable to accomplish the purposes of this Agreement,
including without limitation:

          (a) to file one or more financing or continuation statements, or
amendments thereto, or stock powers or other endorsements or instruments of
transfer or assignments in blank, relative to all or any part of the Pledged
Collateral, or to enter into agreements with Agent and any securities
intermediaries described in Section 1 relating to any Pledged Collateral to
protect Agent's security interest therein, in form and substance satisfactory to
Agent, in each case without the signature of Pledgor;

          (b) after the occurrence and during the continuation of any Event of
Default, to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Pledged Collateral;

          (c) after the occurrence and during the continuation of any Event of
Default, to receive, endorse and collect any instruments made payable to Pledgor
representing any dividend, principal or interest payment or other distribution
in respect of the Pledged Collateral or any part thereof and to give full
discharge for the same; and

          (d) after the occurrence and during the continuation of any Event of
Default, to file any claims or take any action or institute any proceedings that
Agent may deem necessary or desirable for the collection of any of the Pledged
Collateral or otherwise to enforce the rights of Agent with respect to any of
the Pledged Collateral.

          SECTION 9.  AGENT MAY PERFORM.  If Pledgor fails to perform any
                      -----------------                                  
agreement contained herein, Agent may itself perform, or cause performance of,
such agreement, and the expenses of Agent incurred in connection therewith shall
be payable by Pledgor under Section 12(b).

          SECTION 10. STANDARD OF CARE.  The powers conferred on Agent
                      ----------------                                
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Agent shall have no duty as to any Pledged Collateral, it being understood that
Agent shall have no responsibility for (a) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Pledged Collateral, whether or not Agent has or is deemed to
have knowledge of such matters, (b) taking any necessary steps (other than steps
taken in accordance with the standard of care set forth above to maintain
possession of the Pledged Collateral) to preserve rights against any parties
with respect to any Pledged Collateral, (c) taking any necessary steps to
collect or

                                      -9-
<PAGE>
 
realize upon the Secured Obligations or any guarantee therefor, or any part
thereof, or any of the Pledged Collateral, or (d) initiating any action to
protect the Pledged Collateral against the possibility of a decline in market
value. Agent shall be deemed to have exercised reasonable care in the custody
and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Agent accords
its own property consisting of negotiable securities.

          SECTION 11.  REMEDIES.
                       -------- 

          (a) If any Event of Default shall have occurred and be continuing,
Agent may, subject to the terms of the Credit Agreement, exercise in respect of
the Pledged Collateral, in addition to all other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party on default under the Uniform Commercial Code as in effect in any
relevant jurisdiction (the "CODE") (whether or not the Code applies to the
affected Pledged Collateral), and Agent may also in its sole discretion, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale, at any exchange or
broker's board or at any of Agent's offices or elsewhere, for cash, on credit or
for future delivery, at such time or times and at such price or prices and upon
such other terms as Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged Collateral.  Agent
or any Bank may be the purchaser of any or all of the Pledged Collateral at any
such sale and Agent, as agent for and representative of the Banks, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at any such
public sale, to use and apply any of the Secured Obligations as a credit on
account of the purchase price for any Pledged Collateral payable by Agent at
such sale.  Each purchaser at any such sale shall hold the property sold
absolutely free from any claim or right on the part of Pledgor, and Pledgor
hereby waives (to the extent permitted by applicable law) all rights of
redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.
Pledgor agrees that, to the extent notice of sale shall be required by law, at
least ten days' notice to Pledgor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification.  Agent shall not be obligated to make any sale of Pledged
Collateral regardless of notice of sale having been given. Agent may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned.  To the extent permitted by applicable
law, Pledgor hereby waives any claims against Agent arising by reason of the
fact that the price at which any Pledged Collateral may have been sold at any
such private sale was less than the price which might have been obtained at a
public sale, even if Agent accepts the first offer received and does not offer
such Pledged Collateral to more than one offeree.  If the proceeds of any sale
or other disposition of the Pledged Collateral 

                                     -10-
<PAGE>
 
are insufficient to pay all of the Secured Obligations, Pledgor shall be liable
for the deficiency and the reasonable fees of any attorneys employed by Agent to
collect such deficiency.

          (b) Any cash held by Agent as Pledged Collateral and all cash proceeds
received by Agent in respect of any sale of, collection from, or other
realization upon all or any part of the Pledged Collateral may, in the
discretion of Agent, be held by Agent as collateral for, and/or then or at any
time thereafter applied (after payment of any amounts payable to Agent pursuant
to Section 12(b)) in whole or in part by Agent against all or any part of the
Secured Obligations in such order as Agent shall elect.  Any surplus of such
cash or cash proceeds held by Agent and remaining after payment in full of all
the Secured Obligations shall be paid over to Pledgor or to whosoever may be
lawfully entitled to receive such surplus.

          (c) Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended from time to time (the
"SECURITIES ACT"), and applicable state securities laws, Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under the
Securities Act and/or such state securities laws, to conduct such sales as
private, not public, sales and to limit purchasers to a restricted group who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  Pledgor acknowledges and agrees that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering made
pursuant to an effective registration statement under the Securities Act) and,
notwithstanding such circumstances, Pledgor agrees that any such private sale
shall be conclusively deemed to have been made in a commercially reasonable
manner and that Agent shall have no obligation either to engage in public sales
or to delay the sale of any Pledged Collateral for the period of time necessary
to permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would, or should, agree to so register it.  Pledgor further
acknowledges the impossibility of ascertaining the amount of damages which would
be suffered by Agent by reason of the failure by Pledgor to perform any of the
covenants contained in this Section and, consequently, agrees that, if Pledgor
shall fail to perform any of such covenants, it shall pay, as liquidated damages
and not as a penalty, an amount equal to the value of the Pledged Collateral on
the date Agent shall demand compliance with this Section.

          (d) If Agent determines to exercise its right to sell any or all of
the Pledged Collateral, upon written request, Pledgor shall and shall cause each
issuer of any Pledged Shares to be sold hereunder from time to time to furnish
to Agent all such information as Agent may request in order to determine the
number of shares and other

                                     -11-
<PAGE>
 
instruments included in the Pledged Collateral which may be sold by Agent in
exempt transactions under the Securities Act and the rules and regulations of
the Securities and Exchange Commission thereunder, as the same are from time to
time in effect.

          SECTION 12.  INDEMNITY AND EXPENSES.
                       ---------------------- 

          (a) Pledgor agrees to indemnify Agent and each Bank from and against
any and all claims, losses and liabilities in any way relating to, growing out
of or resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses or liabilities result solely from Agent's or such
Bank's gross negligence or willful misconduct as finally determined by a court
of competent jurisdiction.

          (b) Pledgor shall pay to Agent upon demand the amount of any and all
costs and expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, that Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Agent
hereunder, or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

          SECTION 13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
                       -----------------------------------------------      
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the payment in full of all
Secured Obligations, (b) be binding upon Pledgor, its successors and assigns,
and (c) inure, together with the rights and remedies of Agent hereunder, to the
benefit of Agent and its successors, transferees and assigns.  Without limiting
the generality of the foregoing clause (c), any Bank may, subject to the terms
of the Credit Agreement, assign or otherwise transfer its interest in the Credit
Agreement in whole or in part to any other Person, and such other Person shall
thereupon become vested with all benefits in respect thereof granted to Banks
herein or otherwise.  Upon the payment in full of all Secured Obligations, the
security interest granted hereby shall terminate and all rights to the Pledged
Collateral shall revert to Pledgor.  Upon any such termination Agent will, at
Pledgor's expense, execute and deliver to Pledgor such documents as Pledgor
shall reasonably request to evidence such termination and Pledgor shall be
entitled to the return, upon its request and at its expense, against receipt and
without recourse to Agent, of such of the Pledged Collateral as shall not have
been sold or otherwise applied pursuant to the terms hereof.

          SECTION 14.  AMENDMENTS; ETC.  Subject to Section 11.01 of the Credit
                       ---------------                                         
Agreement, no amendment, modification, termination or waiver of any provision of
this Agreement, and no consent to any departure by Pledgor therefrom, shall in
any event be effective unless the same shall be in writing and signed by Agent
and, in the
                                     -12-
<PAGE>
 
case of any such amendment or modification, by Pledgor. Any such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given.

          SECTION 15.  NOTICES.  Any notice or other communication herein
                       -------                                           
required or permitted to be given shall be in writing and may be personally
served or sent by telefacsimile or United States mail or courier service and
shall be deemed to have been given when delivered in person or by courier

depositing it in the United States mail with postage prepaid and properly
addressed.  For the purposes hereof, the address of each party hereto shall be
as set forth under such party's name on the signature pages hereof or, as to
either party, such other address as shall be designated by such party in a
written notice delivered to the other party hereto.

          SECTION 16.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                       -----------------------------------------------------  
No failure or delay on the part of Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 17.  SEVERABILITY.  In case any provision in or obligation
                       ------------                                         
under this Agreement shall be invalid, illegal or unenforceable in any
jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby.

          SECTION 18.  HEADINGS.  Section and subsection headings in this
                       --------

service being hereby acknowledged by Pledgor to be sufficient for personal
jurisdiction in any action against Pledgor in any such court and to be otherwise
effective and binding service in every respect.  Nothing herein shall affect the
right to serve process in any other manner permitted by law or shall limit the
right of Agent to bring proceedings against Pledgor in the courts of any other
jurisdiction.

          SECTION 21.  WAIVER OF JURY TRIAL.  PLEDGOR AND AGENT HEREBY AGREE TO
                       --------------------                                    
WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION

intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach of duty claims, and all
other common law and statutory claims.  Pledgor and Agent each acknowledge that
this waiver is a material inducement for Pledgor and Agent to enter into a
business relationship, that Pledgor and Agent have already relied on this waiver
in entering into this Agreement and that each will continue to rely on this
waiver in their related future dealings.  Pledgor and Agent further warrant and

AGREEMENT.  In the event of litigation, this Agreement may be filed as a written

or any disability or other defense of Company including, without limitation, any
defense based on or arising out of the lack of validity or the unenforceability
of the Secured Obligations or any agreement or instrument relating thereto or by
reason of the cessation of the liability of Company from any cause other than
payment in full of the Secured Obligations;

          (c) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;

          (d) any defense based upon Agent's or any Bank's errors or omissions
in the administration of the Secured Obligations, except behavior which amounts
to bad faith;

          (e) (i) any principles or provisions of law, statutory or otherwise,
which are or might be in conflict with the terms of this Pledge Agreement and
any legal or equitable discharge of such Pledgor's obligations hereunder, (ii)
the benefit of any statute of limitations affecting Pledgor's liability
hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments
and counterclaims, and (iv) promptness, diligence and any requirement that Agent

          SECTION 23.  CERTAIN CALIFORNIA LAW WAIVERS.  As used in this Section
                       ------------------------------                          
23, any reference to "the principal" includes Company, and any reference to "the
creditor" includes Agent and each Bank.  In accordance with Section 2856 of the
California Civil Code:

          (a) Pledgor agrees (i) to waive any and all rights of subrogation and
reimbursement against Company or against any collateral or security granted by
Company for any of the Secured Obligations and (ii) to withhold the exercise of
any and all rights of subrogation, reimbursement and contribution against
Company, against any other guarantor of any of the Secured Obligations and
against any collateral or security granted by any such other guarantor for any
of the Secured Obligations until the Secured Obligations shall have been paid in
full and all letters of credit issued under the Credit Agreement and the other
Loan Documents shall have expired or been canceled, all as more fully set forth
in Section 24;

          (b) Pledgor waives any and all other rights and defenses available to
such Pledgor by reason of Sections 2787 to 2855, inclusive, 2899 and 3433 of the
California Civil Code, including without limitation any and all rights or
defenses Pledgor may have by reason of protection afforded to the principal with
respect to any of the Secured Obligations, or to any other guarantor of any of
the Secured Obligations with respect to any of such guarantor's obligations
under its guaranty, in either case pursuant to the antideficiency or other laws
of the State of California limiting or discharging the principal's indebtedness
or such guarantor's obligations, including without limitation Section 580a,
580b, 580d, or 726 of the California Code of Civil Procedure; and

          (c) Pledgor waives all rights and defenses arising out of an election
of remedies by the creditor, even though that election of remedies, such as a
nonjudicial foreclosure with respect to security for any Secured Obligation, has
destroyed Pledgor's rights of subrogation and reimbursement against the
principal by the operation of Section 580d of the Code of Civil Procedure or
otherwise; and even though that election of remedies by the creditor, such as
nonjudicial foreclosure with respect to security for an obligation of any other
guarantor (including any other Pledgor) of any of the Secured Obligations, has
destroyed Pledgor's rights of contribution against such other guarantor.

No other provision of this Pledge Agreement shall be construed as limiting the
generality of any of the covenants and waivers set forth in this Section 23.

          SECTION 24.  PLEDGOR'S RIGHTS OF SUBROGATION, CONTRIBUTION, ETC.
                       -------------------------------------------------- 
Pledgor hereby waives any claim, right or remedy, direct or indirect, that
Pledgor now has or may hereafter have against Company or any of its assets in
connection with this Pledge Agreement or the performance by Pledgor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute (including without limitation under
California Civil Code Section 2847, 2848 or 2849), under common law or otherwise
and including without limitation (a) any right of subrogation, reimbursement or
indemnification that Pledgor now has or may hereafter have against Company, (b)
any right to enforce, or to participate in, any claim, right or remedy that
Agent or any Bank now has or may hereafter have against Company, and (c) any
benefit of, and any right to participate in, any collateral or security now or
hereafter held by Agent or any Bank.  In addition, until the Secured Obligations
shall have been indefeasibly paid in full and all letters of credit issued under
the Credit Agreement shall have expired or been canceled, Pledgor shall withhold
exercise of any right of contribution Pledgor may have against any other
guarantor of the Secured Obligations (including without limitation any such
right of contribution under California Civil Code Section 2848).  Pledgor
further agrees that, to the extent the waiver or agreement to withhold the
exercise of its rights of subrogation, reimbursement, indemnification and
contribution as set forth herein is found by a court of competent jurisdiction
to be void or voidable for any reason, any rights of subrogation, reimbursement
or indemnification Pledgor may have against Company or against any collateral or
security, and any rights of contribution Pledgor may have against any such other
guarantor, shall be junior and subordinate to any rights Agent or any Bank may
have against Company, to all right, title and interest Agent or any Bank may
have in any such collateral or security, and to any right Agent or any Bank may
have against such other guarantor.  If any amount shall be paid to Pledgor on
account of any such subrogation, reimbursement, indemnification or contribution
rights at any time when all Secured Obligations shall not have been paid in
full, such amount shall be held in trust for Agent on behalf of Banks and shall
forthwith be paid over to Agent for the benefit of Banks to be credited and
applied against the Secured Obligations, whether matured or unmatured, in
accordance with the terms hereof.

          SECTION 25.  COUNTERPARTS.  This Agreement may be executed in one or
                       ------------                                           
more counterparts and by different parties hereto in separate counterparts, each
of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.

against Pledgor or any of the Pledged Collateral as a result of the failure to
make such payment.

          SECTION 6.  FURTHER ASSURANCES; PLEDGE AMENDMENTS.
                      ------------------------------------- 

          (a) Pledgor agrees that from time to time, at the expense of Pledgor,
Pledgor will promptly execute and deliver all further instruments and documents,
and take all further action, that may be necessary or desirable, or that Agent
may request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable Agent to exercise and enforce its
rights and remedies hereunder with respect to any Pledged Collateral.  Without
limiting the generality of the foregoing, Pledgor will:  (i) execute and file
such financing or continuation statements, or amendments thereto, and such other
instruments or notices (including, without limitation, stock powers with respect
to, or other endorsements or instruments necessary to effect the assignment or
other transfer of, any of the Pledged Collateral), as may be necessary or
desirable, or as Agent may request, in order to perfect and preserve the
security interests granted or purported to be granted hereby and (ii) at Agent's
request, appear in and defend any action or proceeding that may affect 

                                      -6-
<PAGE>
 
Pledgor's title to or Agent's security interest in all or any part of the
Pledged Collateral.

          (b) Pledgor further agrees that it will, upon obtaining any additional
shares of stock or other securities required to be pledged hereunder as provided
in Section 5(b), promptly (and in any event within five Business Days) deliver
to Agent a Pledge Amendment, duly executed by Pledgor, in substantially the form
of Schedule IV annexed hereto (a "PLEDGE AMENDMENT"), in respect of the
   -----------                                                         
additional Pledged Interests to be pledged pursuant to this Agreement.  Pledgor
hereby authorizes Agent to attach each Pledge Amendment to this Agreement and
agrees that all Pledged Interests listed on any Pledge Amendment delivered to
Agent shall for all purposes hereunder be considered Pledged Collateral;
provided, however, that the failure of Pledgor to execute a Pledge Amendment
--------  -------                                                           
with respect to any additional Pledged Interests pledged pursuant to this
Agreement shall not impair the security interest of Agent therein or otherwise
adversely affect the rights and remedies of Agent hereunder with respect
thereto.

          SECTION 7.  VOTING RIGHTS; DIVIDENDS; ETC.
                      ------------------------------

          (a) So long as no Event of Default shall have occurred and be
continuing:

              (i)   Pledgor shall be entitled to exercise any and all voting and
other consensual rights pertaining to the Pledged Collateral or any part thereof
for any purpose not inconsistent with the terms of this Agreement or the Credit
Agreement; provided, however, that Pledgor shall not exercise or refrain from
           --------  -------                                                 
exercising any such right if Agent shall have notified Pledgor that, in Agent's
judgment, such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof;

              (ii)  Pledgor shall be entitled to receive and retain, and to
utilize free and clear of the lien of this Agreement, any and all dividends and
interest paid in respect of the Pledged Collateral; provided, however, that any
                                                    --------  -------
and all

                    (A) dividends and interest paid or payable other than in
cash in respect of, and instruments and other property received, receivable or
otherwise distributed in respect of, or in exchange for, any Pledged Collateral,

                    (B) dividends and other distributions paid or payable in
cash in respect of any Pledged Collateral in connection with (x) a partial or
total liquidation or dissolution, (y) a reduction of capital, capital surplus or
paid-in-surplus or (z) a quasi-reorganization, and

                                      -7-
<PAGE>
 
                    (C) cash paid, payable or otherwise distributed in respect
of principal or in redemption of or in exchange for any Pledged Collateral,
shall be, and shall forthwith be delivered to Agent to hold as, Pledged
Collateral and shall, if received by Pledgor, be received in trust for the
benefit of Agent, be segregated from the other property or funds of Pledgor and
be forthwith delivered to Agent as Pledged Collateral in the same form as so
received (with all necessary endorsements); and

              (iii) Agent shall promptly execute and deliver (or cause to be
executed and delivered) to Pledgor all such proxies, dividend payment orders and
other instruments as Pledgor may from time to time reasonably request for the
purpose of enabling Pledgor to exercise the voting and other consensual rights
which it is entitled to exercise pursuant to paragraph (i) above and to receive
the dividends, principal or interest payments which it is authorized to receive
and retain pursuant to paragraph (ii) above.

          (b) Upon the occurrence and during the continuation of any Default or
Event of Default:

              (i)   upon written notice from Agent to Pledgor, all rights of
Pledgor to exercise the voting and other consensual rights which it would
otherwise be entitled to exercise pursuant to Section 7(a)(i) shall cease, and
all such rights shall thereupon become vested in Agent who shall thereupon have
the sole right to exercise such voting and other consensual rights;

              (ii)  all rights of Pledgor to receive the dividends and interest
payments which it would otherwise be authorized to receive and retain pursuant
to Section 7(a)(ii) shall cease, and all such rights shall thereupon become
vested in Agent who shall thereupon have the sole right to receive and hold as
Pledged Collateral such dividends and interest payments; and

              (iii) all dividends, principal and interest payments which are
received by Pledgor contrary to the provisions of paragraph (ii) of this Section
7(b) shall be received in trust for the benefit of Agent, shall be segregated
from other funds of Pledgor and shall forthwith be paid over to Agent as Pledged
Collateral in the same form as so received (with any necessary endorsements).

          (c) In order to permit Agent to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section
7(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Agent all such proxies, dividend payment orders 

                                      -8-
<PAGE>
 
and other instruments as Agent may from time to time reasonably request and (ii)
without limiting the effect of the immediately preceding clause (i), Pledgor
hereby grants to Agent an irrevocable proxy to vote the Pledged Collateral and
to exercise all other rights, powers, privileges and remedies to which a holder
of the Pledged Collateral would be entitled (including, without limitation,
giving or withholding written consents of shareholders, calling special meetings
of shareholders and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Collateral on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Collateral or any officer or agent
thereof), upon the occurrence of an Event of Default or Default and which proxy
shall only terminate upon the payment in full of the Secured Obligations.

          SECTION 8.  AGENT APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby
                      --------------------------------                 
irrevocably appoints Agent as Pledgor's attorney-in-fact, with full authority in
the place and stead of Pledgor and in the name of Pledgor, Agent or otherwise,
from time to time in Agent's discretion to take any action and to execute any
instrument that Agent may deem necessary or advisable to accomplish the purposes
of this Agreement, including without limitation:

          (a) to file one or more financing or continuation statements, or
amendments thereto, or stock powers or other endorsements or instruments of
transfer or assignments in blank, relative to all or any part of the Pledged
Collateral, or to enter into agreements with Agent and any securities
intermediaries described in Section 1 relating to any Pledged Collateral to
protect Agent's security interest therein, in form and substance satisfactory to
Agent, in each case without the signature of Pledgor;

          (b) after the occurrence and during the continuation of any Event of
Default, to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Pledged Collateral;

          (c) after the occurrence and during the continuation of any Event of
Default, to receive, endorse and collect any instruments made payable to Pledgor
representing any dividend, principal or interest payment or other distribution
in respect of the Pledged Collateral or any part thereof and to give full
discharge for the same; and

          (d) after the occurrence and during the continuation of any Event of
Default, to file any claims or take any action or institute any proceedings that
Agent may deem necessary or desirable for the collection of any of the Pledged
Collateral or otherwise to enforce the rights of Agent with respect to any of
the Pledged Collateral.

                                      -9-
<PAGE>
 
          SECTION 9.  AGENT MAY PERFORM.  If Pledgor fails to perform any
                      -----------------                                  
agreement contained herein, Agent may itself perform, or cause performance of,
such agreement, and the expenses of Agent incurred in connection therewith shall
be payable by Pledgor under Section 12(b).

          SECTION 10.  STANDARD OF CARE.  The powers conferred on Agent
                       ----------------                                
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Agent shall have no duty as to any Pledged Collateral, it being understood that
Agent shall have no responsibility for (a) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Pledged Collateral, whether or not Agent has or is deemed to
have knowledge of such matters, (b) taking any necessary steps (other than steps
taken in accordance with the standard of care set forth above to maintain
possession of the Pledged Collateral) to preserve rights against any parties
with respect to any Pledged Collateral, (c) taking any necessary steps to
collect or realize upon the Secured Obligations or any guarantee therefor, or
any part thereof, or any of the Pledged Collateral, or (d) initiating any action
to protect the Pledged Collateral against the possibility of a decline in market
value.  Agent shall be deemed to have exercised reasonable care in the custody
and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Agent accords
its own property consisting of negotiable securities.

          SECTION 11.  REMEDIES.
                       -------- 

          (a) If any Event of Default shall have occurred and be continuing,
Agent may, subject to the terms of the Credit Agreement, exercise in respect of
the Pledged Collateral, in addition to all other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party on default under the Uniform Commercial Code as in effect in any
relevant jurisdiction (the "CODE") (whether or not the Code applies to the
affected Pledged Collateral), and Agent may also in its sole discretion, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale, at any exchange or
broker's board or at any of Agent's offices or elsewhere, for cash, on credit or
for future delivery, at such time or times and at such price or prices and upon
such other terms as Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged Collateral.  Agent
or any Bank may be the purchaser of any or all of the Pledged Collateral at any
such sale and Agent, as agent for and representative of the Banks, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at any such
public sale, to use and apply any of the Secured Obligations as a credit on
account of the purchase price for any Pledged 

                                     -10-
<PAGE>
 
Collateral payable by Agent at such sale. Each purchaser at any such sale shall
hold the property sold absolutely free from any claim or right on the part of
Pledgor, and Pledgor hereby waives (to the extent permitted by applicable law)
all rights of redemption, stay and/or appraisal which it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted. Pledgor agrees that, to the extent notice of sale shall be
required by law, at least ten days' notice to Pledgor of the time and place of
any public sale or the time after which any private sale is to be made shall
constitute reasonable notification. Agent shall not be obligated to make any
sale of Pledged Collateral regardless of notice of sale having been given. Agent
may adjourn any public or private sale from time to time by announcement at the
time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned. To the extent permitted
by applicable law, Pledgor hereby waives any claims against Agent arising by
reason of the fact that the price at which any Pledged Collateral may have been
sold at any such private sale was less than the price which might have been
obtained at a public sale, even if Agent accepts the first offer received and
does not offer such Pledged Collateral to more than one offeree. If the proceeds
of any sale or other disposition of the Pledged Collateral are insufficient to
pay all of the Secured Obligations, Pledgor shall be liable for the deficiency
and the reasonable fees of any attorneys employed by Agent to collect such
deficiency.

          (b) Any cash held by Agent as Pledged Collateral and all cash proceeds
received by Agent in respect of any sale of, collection from, or other
realization upon all or any part of the Pledged Collateral may, in the
discretion of Agent, be held by Agent as collateral for, and/or then or at any
time thereafter applied (after payment of any amounts payable to Agent pursuant
to Section 12(b)) in whole or in part by Agent against all or any part of the
Secured Obligations in such order as Agent shall elect.  Any surplus of such
cash or cash proceeds held by Agent and remaining after payment in full of all
the Secured Obligations shall be paid over to Pledgor or to whosoever may be
lawfully entitled to receive such surplus.

          (c) Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended from time to time (the
"SECURITIES ACT"), and applicable state securities laws, Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under the
Securities Act and/or such state securities laws, to conduct such sales as
private, not public, sales and to limit purchasers to a restricted group who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  Pledgor acknowledges and agrees that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering made
pursuant to an effective registration statement under the Securities Act) and,

                                     -11-
<PAGE>
 
notwithstanding such circumstances, Pledgor agrees that any such private sale
shall be conclusively deemed to have been made in a commercially reasonable
manner and that Agent shall have no obligation either to engage in public sales
or to delay the sale of any Pledged Collateral for the period of time necessary
to permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would, or should, agree to so register it.  Pledgor further
acknowledges the impossibility of ascertaining the amount of damages which would
be suffered by Agent by reason of the failure by Pledgor to perform any of the
covenants contained in this Section and, consequently, agrees that, if Pledgor
shall fail to perform any of such covenants, it shall pay, as liquidated damages
and not as a penalty, an amount equal to the value of the Pledged Collateral on
the date Agent shall demand compliance with this Section.

          (d) If Agent determines to exercise its right to sell any or all of
the Pledged Collateral, upon written request, Pledgor shall and shall cause each
issuer of any Pledged Interests to be sold hereunder from time to time to
furnish to Agent all such information as Agent may request in order to determine
the number of shares and other instruments included in the Pledged Collateral
which may be sold by Agent in exempt transactions under the Securities Act and
the rules and regulations of the Securities and Exchange Commission thereunder,
as the same are from time to time in effect.

          SECTION 12.  INDEMNITY AND EXPENSES.
                       ---------------------- 

          (a) Pledgor agrees to indemnify Agent and each Bank from and against
any and all claims, losses and liabilities in any way relating to, growing out
of or resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses or liabilities result solely from Agent's or such
Bank's gross negligence or willful misconduct as finally determined by a court
of competent jurisdiction.

          (b) Pledgor shall pay to Agent upon demand the amount of any and all
costs and expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, that Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Agent
hereunder, or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

          SECTION 13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
                       -----------------------------------------------      
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the payment in full of all
Secured Obligations, (b) be binding upon Pledgor, its successors and assigns,
and (c) inure, 

                                     -12-
<PAGE>
 
together with the rights and remedies of Agent hereunder, to the benefit of
Agent and its successors, transferees and assigns. Without limiting the
generality of the foregoing clause (c), any Bank may, subject to the terms of
the Credit Agreement, assign or otherwise transfer its interest in the Credit
Agreement in whole or in part to any other Person, and such other Person shall
thereupon become vested with all benefits in respect thereof granted to Banks
herein or otherwise. Upon the payment in full of all Secured Obligations, the
security interest granted hereby shall terminate and all rights to the Pledged
Collateral shall revert to Pledgor. Upon any such termination Agent will, at
Pledgor's expense, execute and deliver to Pledgor such documents as Pledgor
shall reasonably request to evidence such termination and Pledgor shall be
entitled to the return, upon its request and at its expense, against receipt and
without recourse to Agent, of such of the Pledged Collateral as shall not have
been sold or otherwise applied pursuant to the terms hereof.

          SECTION 14.  AMENDMENTS; ETC.  Subject to Section 11.01 of the Credit
                       ---------------                                         
Agreement, no amendment, modification, termination or waiver of any provision of
this Agreement, and no consent to any departure by Pledgor therefrom, shall in
any event be effective unless the same shall be in writing and signed by Agent
and, in the case of any such amendment or modification, by Pledgor.  Any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which it was given.

          SECTION 15.  NOTICES.  Any notice or other communication herein
                       -------                                           
required or permitted to be given shall be in writing and may be personally
served or sent by telefacsimile or United States mail or courier service and
shall be deemed to have been given when delivered in person or by courier
service, upon receipt of telefacsimile or five (5) Business Days after
depositing it in the United States mail with postage prepaid and properly
addressed.  For the purposes hereof, the address of each party hereto shall be
as set forth under such party's name on the signature pages hereof or, as to
either party, such other address as shall be designated by such party in a
written notice delivered to the other party hereto.

          SECTION 16.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                       -----------------------------------------------------  
No failure or delay on the part of Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 17.  SEVERABILITY.  In case any provision in or obligation
                       ------------                                         
under this Agreement shall be invalid, illegal or unenforceable in any
jurisdiction, the 

                                     -13-
<PAGE>
 
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

          SECTION 18.  HEADINGS.  Section and subsection headings in this
                       --------                                          
Agreement are included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose or be given any
substantive effect.

          SECTION 19.  GOVERNING LAW; TERMS.  THIS AGREEMENT AND THE RIGHTS AND
                       --------------------                                    
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF
CALIFORNIA, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO THE EXTENT
THAT THE CODE PROVIDES THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST
HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR PLEDGED
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF
CALIFORNIA. Unless otherwise defined herein or in the Credit Agreement, terms
used in Articles 8 and 9 of the UCC are used herein as therein defined.

          SECTION 20.  CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  ALL
                       ----------------------------------------------      
JUDICIAL PROCEEDINGS BROUGHT AGAINST PLEDGOR ARISING OUT OF OR RELATING TO THIS
AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE
UNITED STATES FOR THE CENTRAL DISTRICT OF CALIFORNIA, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT PLEDGOR ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS
PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE
AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS AND IRREVOCABLY
AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS
AGREEMENT.  Pledgor hereby agrees that service of all process in any such
proceeding in any such court may be made by registered or certified mail, return
receipt requested, to Pledgor at its address provided in Section 15, such
service being hereby acknowledged by Pledgor to be sufficient for personal
jurisdiction in any action against Pledgor in any such court and to be otherwise
effective and binding service in every respect.  Nothing herein shall affect the
right to serve process in any other manner permitted by law or shall limit the
right of Agent to bring proceedings against Pledgor in the courts of any other
jurisdiction.

          SECTION 21.  WAIVER OF JURY TRIAL.  PLEDGOR AND AGENT HEREBY AGREE TO
                       --------------------                                    
WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF THIS AGREEMENT.  The scope of this waiver is
intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach of duty claims, and all
other common law and statutory claims.  Pledgor and Agent each acknowledge that
this waiver is a material inducement for Pledgor and Agent to enter into a
business relationship, that Pledgor and Agent have already relied on this waiver
in entering into this Agreement and that each will continue to rely on this
waiver in their related future dealings.  Pledgor and Agent further warrant and
represent that each has reviewed this waiver with its legal counsel, and that
each knowingly and voluntarily waives its jury trial rights following
consultation with legal counsel.  THIS WAIVER IS IRREVOCABLE, MEANING THAT IT
MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO
ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT.  In the event of litigation, this Agreement may be filed as a written
consent to a trial by the court.

          SECTION 22.    WAIVERS BY PLEDGOR.  Pledgor hereby waives, for the
                         ------------------                                 
benefit of Banks and Agent:

          (a) any right to require Agent or any Bank, as a condition of payment
or performance by Pledgor, to (i) proceed against Company, any other guarantor
of the Secured Obligations or any other Person, (ii) proceed against or exhaust
any security held from Company, any such other guarantor or any other Person,
(iii) proceed against or have resort to any balance of any deposit account or
credit on the books of Agent or any Bank in favor of Company or any other
Person, or (iv) pursue any other remedy in the power of Agent or any Bank

          (b) any defense arising by reason of the incapacity, lack of authority
or any disability or other defense of Company including, without limitation, any

          SECTION 23.   CERTAIN CALIFORNIA LAW WAIVERS.  As used in this Section
                        ------------------------------                          
23, any reference to "the principal" includes Company, and any reference to "the
creditor" includes Agent and each Bank.  In accordance with Section 2856 of the
California Civil Code:

          (a) Pledgor agrees (i) to waive any and all rights of subrogation and
reimbursement against Company or against any collateral or security granted by
Company for any of the Secured Obligations and (ii) to withhold the exercise of
any and all rights of subrogation, reimbursement and contribution against
Company, against any other guarantor of any of the Secured Obligations and
against any collateral or security granted by any such other guarantor for any
of the Secured Obligations until the Secured Obligations shall have been paid in
full and all letters of credit issued under the Credit Agreement and the other
Loan Documents shall have expired or been cancelled, all as more fully set forth
in Section 24;

          (b) Pledgor waives any and all other rights and defenses available to
such Pledgor by reason of Sections 2787 to 2855, inclusive, 2899 and 3433 of the
California Civil Code, including without limitation any and all rights or
defenses Pledgor may have by reason of protection afforded to the principal with
respect to any of the Secured Obligations, or to any other guarantor of any of
the Secured Obligations 

                                     -16-
<PAGE>
 
with respect to any of such guarantor's obligations under its guaranty, in
either case pursuant to the antideficiency or other laws of the State of
California limiting or discharging the principal's indebtedness or such
guarantor's obligations, including without limitation Section 580a, 580b, 580d,
or 726 of the California Code of Civil Procedure; and

          (c) Pledgor waives all rights and defenses arising out of an election
of remedies by the creditor, even though that election of remedies, such as a
nonjudicial foreclosure with respect to security for any Secured Obligation, has
destroyed Pledgor's rights of subrogation and reimbursement against the
principal by the operation of Section 580d of the Code of Civil Procedure or
otherwise; and even though that election of remedies by the creditor, such as
nonjudicial foreclosure with respect to security for an obligation of any other
guarantor (including any other Pledgor) of any of the Secured Obligations, has
destroyed Pledgor's rights of contribution against such other guarantor.

No other provision of this Pledge Agreement shall be construed as limiting the
generality of any of the covenants and waivers set forth in this Section 23.

          SECTION 24.   PLEDGOR'S RIGHTS OF SUBROGATION, CONTRIBUTION, ETC.
                        -------------------------------------------------- 
Pledgor hereby waives any claim, right or remedy, direct or indirect, that
Pledgor now has or may hereafter have against Company or any of its assets in
connection with this Pledge Agreement or the performance by Pledgor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute (including without limitation under
California Civil Code Section 2847, 2848 or 2849), under common law or otherwise
and including without limitation (a) any right of subrogation, reimbursement or
indemnification that Pledgor now has or may hereafter have against Company, (b)
any right to enforce, or to participate in, any claim, right or remedy that
Agent or any Bank now has or may hereafter have against Company, and (c) any
benefit of, and any right to participate in, any collateral or security now or
hereafter held by Agent or any Bank.  In addition, until the Secured Obligations
shall have been indefeasibly paid in full and all letters of credit issued under
the Credit Agreement shall have expired or been cancelled, Pledgor shall
withhold exercise of any right of contribution Pledgor may have against any
other guarantor of the Secured Obligations (including without limitation any
such right of contribution under California Civil Code Section 2848).  Pledgor
further agrees that, to the extent the waiver or agreement to withhold the
exercise of its rights of subrogation, reimbursement, indemnification and
contribution as set forth herein is found by a court of competent jurisdiction
to be void or voidable for any reason, any rights of subrogation, reimbursement
or indemnification Pledgor may have against Company or against any collateral or
security, and any rights of contribution Pledgor may have against any such other
guarantor, shall be junior and subordinate to any rights Agent or any Bank may
have against Company, to all right, title and interest Agent or any Bank may
have in 

                                     -17-
<PAGE>
 
any such collateral or security, and to any right Agent or any Bank may have
against such other guarantor. If any amount shall be paid to Pledgor on account
of any such subrogation, reimbursement, indemnification or contribution rights
at any time when all Secured Obligations shall not have been paid in full, such
amount shall be held in trust for Agent on behalf of Banks and shall forthwith
be paid over to Agent for the benefit of Banks to be credited and applied
against the Secured Obligations, whether matured or unmatured, in accordance
with the terms hereof.

          SECTION 25.  FURTHER DOCUMENTATION.  Pledgor hereby agrees to promptly
                       ---------------------                                    
execute and deliver all further instruments and documents (including any
financing statements, continuations or amendments of such financing statements
and any consents necessary for the authorization of the transactions
contemplated hereby) and take all further action that may be necessary or
desirable, or that Agent may request, in order to perfect and protect any
security interest granted or purported to be granted hereby or to enable Agent
to exercise and enforce the rights and remedies of Agent hereunder with respect
to any Pledged Collateral or to carry out the provisions and purposes hereof.

          SECTION 26.  COUNTERPARTS.  This Agreement may be executed in one or
                       ------------                                           
more counterparts and by different parties hereto in separate counterparts, each
of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.

                                     -18-

          IN WITNESS WHEREOF, Pledgor and Agent have caused this Agreement to be
duly executed and delivered by their respective officers thereunto duly
authorized as of the date first written above.

Pledgor now or hereafter existing under this Agreement and under any other Loan

          SECTION 6.  FURTHER ASSURANCES; PLEDGE AMENDMENTS.
                      ------------------------------------- 

          (a) Pledgor agrees that from time to time, at the expense of Pledgor,
Pledgor will promptly execute and deliver all further instruments and documents,
and take all further action, that may be necessary or desirable, or that Agent
may request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable Agent to exercise and enforce its
rights and remedies hereunder with respect to any Pledged Collateral.  Without
limiting the generality of the foregoing, Pledgor will:  (i) execute and file
such financing or continuation statements, or amendments thereto, and such other
instruments or notices (including, without limitation, stock powers with respect
to, or other endorsements or instruments necessary to effect the assignment or
other transfer of, any of the Pledged Collateral), as may be necessary or
desirable, or as Agent may request, in order to perfect and preserve the
security interests granted or purported to be granted hereby and (ii) at Agent's
request, appear in and defend any action or proceeding that may affect Pledgor's
title to or Agent's security interest in all or any part of the Pledged
Collateral.

          (b) Pledgor further agrees that it will, upon obtaining any additional
shares of stock or other securities required to be pledged hereunder as provided
in Section 5(b), promptly (and in any event within five Business Days) deliver
to Agent a Pledge Amendment, duly executed by Pledgor, in substantially the form
of Schedule IV annexed hereto (a "PLEDGE AMENDMENT"), in respect of the
   -----------                                                         
additional Pledged Shares to be pledged pursuant to this Agreement.  Pledgor
hereby authorizes Agent to attach each Pledge Amendment to this Agreement and
agrees that all Pledged Shares listed on any Pledge Amendment delivered to Agent
shall for all purposes hereunder be considered Pledged Collateral; provided,
                                                                   -------- 
however, that the failure of Pledgor to execute a Pledge Amendment with respect
-------                                                                        
to any additional Pledged Shares pledged pursuant to this Agreement shall not
impair the security interest of Agent therein or otherwise adversely affect the
rights and remedies of Agent hereunder with respect thereto.

          SECTION 7.  VOTING RIGHTS; DIVIDENDS; ETC.
                      ------------------------------

          (a) So long as no Event of Default shall have occurred and be
continuing:

          (i) Pledgor shall be entitled to exercise any and all voting and other
consensual rights pertaining to the Pledged Collateral or any part thereof for
any purpose not inconsistent with the terms of this Agreement or the Credit
Agreement; provided, however, that Pledgor shall not exercise or refrain from
           --------  -------                                                 
exercising any such right if Agent shall have notified Pledgor that, in Agent's
judgment, such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof;

          (ii) Pledgor shall be entitled to receive and retain, and to utilize
free and clear of the lien of this Agreement, any and all dividends and interest
paid in respect of the Pledged Collateral; provided, however, that any and all
                                           --------  -------

wise distributed in respect of, or in exchange for, any Pledged Collateral,

              (B) dividends and other distributions paid or payable in cash in
respect of any Pledged Collateral in connection with (x) a partial or total
liquidation or dissolution, (y) a reduction of capital, capital surplus or paid-
in-surplus or (z) a quasi-reorganization, and

              (C) cash paid, payable or otherwise distributed in respect of
principal or in redemption of or in exchange for any Pledged Collateral,

shall be, and shall forthwith be delivered to Agent to hold as, Pledged
Collateral and shall, if received by Pledgor, be received in trust for the
benefit of Agent, be segregated from the other property or funds of Pledgor and
be forthwith delivered to Agent as Pledged Collateral in the same form as so
received (with all necessary endorsements); and

          (iii)  Agent shall promptly execute and deliver (or cause to be
executed and delivered) to Pledgor all such proxies, dividend payment orders and
other instruments as Pledgor may from time to time reasonably request for the
purpose of enabling Pledgor to exercise the voting and other consensual rights
which it is entitled to exercise pursuant to paragraph (i) above and to receive
the dividends, principal or interest payments which it is authorized to receive
and retain pursuant to paragraph (ii) above.

                                      -7-
<PAGE>
 
       (b) Upon the occurrence and during the continuation of any Default or
Event of Default:

          (i) upon written notice from Agent to Pledgor, all rights of Pledgor
to exercise the voting and other consensual rights which it would otherwise be
entitled to exercise pursuant to Section 7(a)(i) shall cease, and all such
rights shall thereupon become vested in Agent who shall thereupon have the sole
right to exercise such voting and other consensual rights;

          (ii) all rights of Pledgor to receive the dividends and interest
payments which it would otherwise be authorized to receive and retain pursuant
to Section 7(a)(ii) shall cease, and all such rights shall thereupon become
vested in Agent who shall thereupon have the sole right to receive and hold as
Pledged Collateral such dividends and interest payments; and

         (iii) all dividends, principal and interest payments which
are received by Pledgor contrary to the provisions of paragraph (ii) of this
Section 7(b) shall be received in trust for the benefit of Agent, shall be
segregated from other funds of Pledgor and shall forthwith be paid over to Agent
as Pledged Collateral in the same form as so received (with any necessary
endorsements).

     (c) In order to permit Agent to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section
7(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Agent all such proxies, dividend payment orders and other instruments as Agent
may from time to time reasonably request and (ii) without limiting the effect of
the immediately preceding clause (i), Pledgor hereby grants to Agent an
irrevocable proxy to vote the Pledged Collateral and to exercise all other
rights, powers, privileges and remedies to which a holder of the Pledged
Collateral would be entitled (including, without limitation, giving or
withholding written consents of shareholders, calling special meetings of
shareholders and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Collateral on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Collateral or any officer or agent
thereof), upon the occurrence of an Event of Default or Default and which proxy
shall only terminate upon the payment in full of the Secured Obligations.

          SECTION 8.  AGENT APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby
                      --------------------------------                 
irrevocably appoints Agent as Pledgor's attorney-in-fact, with full authority in
the place and stead of Pledgor and in the name of Pledgor, Agent or otherwise,
from time to time in Agent's discretion to take any action and to execute any
instrument that Agent may


                                      -8-
<PAGE>
 
deem necessary or advisable to accomplish the purposes of this Agreement,
including without limitation:

          (a) to file one or more financing or continuation statements, or
amendments thereto, or stock powers or other endorsements or instruments of
transfer or assignments in blank, relative to all or any part of the Pledged
Collateral, or to enter into agreements with Agent and any securities
intermediaries described in Section 1 relating to any Pledged Collateral to
protect Agent's security interest therein, in form and substance satisfactory to
Agent, in each case without the signature of Pledgor;

          (b) after the occurrence and during the continuation of any Event of
Default, to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Pledged Collateral;

          (c) after the occurrence and during the continuation of any Event of
Default, to receive, endorse and collect any instruments made payable to Pledgor
representing any dividend, principal or interest payment or other distribution
in respect of the Pledged Collateral or any part thereof and to give full
discharge for the same; and

          (d) after the occurrence and during the continuation of any Event of
Default, to file any claims or take any action or institute any proceedings that
Agent may deem necessary or desirable for the collection of any of the Pledged
Collateral or otherwise to enforce the rights of Agent with respect to any of
the Pledged Collateral.

          SECTION 9.  AGENT MAY PERFORM.  If Pledgor fails to perform any
                      -----------------                                  
agreement contained herein, Agent may itself perform, or cause performance of,
such agreement, and the expenses of Agent incurred in connection therewith shall
be payable by Pledgor under Section 12(b).

          SECTION 10.  STANDARD OF CARE.  The powers conferred on Agent
                       ----------------                                
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Agent shall have no duty as to any Pledged Collateral, it being understood that
Agent shall have no responsibility for (a) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Pledged Collateral, whether or not Agent has or is deemed to
have knowledge of such matters, (b) taking any necessary steps (other than steps
taken in accordance with the standard of care set forth above to maintain
possession of the Pledged Collateral) to preserve rights against any parties
with respect to any Pledged Collateral, (c) taking any necessary steps to
collect or

                                      -9-
<PAGE>
 
realize upon the Secured Obligations or any guarantee therefor, or any part
thereof, or any of the Pledged Collateral, or (d) initiating any action to
protect the Pledged Collateral against the possibility of a decline in market
value. Agent shall be deemed to have exercised reasonable care in the custody
and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Agent accords
its own property consisting of negotiable securities.

          SECTION 11.  REMEDIES.
                       -------- 

          (a) If any Event of Default shall have occurred and be continuing,
Agent may, subject to the terms of the Credit Agreement, exercise in respect of
the Pledged Collateral, in addition to all other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party on default under the Uniform Commercial Code as in effect in any
relevant jurisdiction (the "CODE") (whether or not the Code applies to the
affected Pledged Collateral), and Agent may also in its sole discretion, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale, at any exchange or
broker's board or at any of Agent's offices or elsewhere, for cash, on credit or
for future delivery, at such time or times and at such price or prices and upon
such other terms as Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged Collateral.  Agent
or any Bank may be the purchaser of any or all of the Pledged Collateral at any
such sale and Agent, as agent for and representative of the Banks, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at any such
public sale, to use and apply any of the Secured Obligations as a credit on
account of the purchase price for any Pledged Collateral payable by Agent at
such sale.  Each purchaser at any such sale shall hold the property sold
absolutely free from any claim or right on the part of Pledgor, and Pledgor
hereby waives (to the extent permitted by applicable law) all rights of
redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.
Pledgor agrees that, to the extent notice of sale shall be required by law, at
least ten days' notice to Pledgor of the time and place of any public sale or
the time after which any private sale is to be made shall constitute reasonable
notification.  Agent shall not be obligated to make any sale of Pledged
Collateral regardless of notice of sale having been given. Agent may adjourn any
public or private sale from time to time by announcement at the time and place
fixed therefor, and such sale may, without further notice, be made at the time
and place to which it was so adjourned.  To the extent permitted by applicable
law, Pledgor hereby waives any claims against Agent arising by reason of the
fact that the price at which any Pledged Collateral may have been sold at any
such private sale was less than the price which might have been obtained at a
public sale, even if Agent accepts the first offer received and does not offer
such Pledged Collateral to more than one offeree.  If the proceeds of any sale
or other disposition of the Pledged Collateral

                                     -10-
<PAGE>
 
are insufficient to pay all of the Secured Obligations, Pledgor shall be liable
for the deficiency and the reasonable fees of any attorneys employed by Agent to
collect such deficiency.

          (b) Any cash held by Agent as Pledged Collateral and all cash proceeds
received by Agent in respect of any sale of, collection from, or other realiza
tion upon all or any part of the Pledged Collateral may, in the discretion of
Agent, be held by Agent as collateral for, and/or then or at any time thereafter
applied (after payment of any amounts payable to Agent pursuant to Section
12(b)) in whole or in part by Agent against all or any part of the Secured
Obligations in such order as Agent shall elect.  Any surplus of such cash or
cash proceeds held by Agent and remaining after payment in full of all the
Secured Obligations shall be paid over to Pledgor or to whosoever may be
lawfully entitled to receive such surplus.

          (c) Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended from time to time (the
"SECURITIES ACT"), and applicable state securities laws, Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under the
Securities Act and/or such state securities laws, to conduct such sales as
private, not public, sales and to limit purchasers to a restricted group who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  Pledgor acknowledges and agrees that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering made
pursuant to an effective registration statement under the Securities Act) and,
notwithstanding such circumstances, Pledgor agrees that any such private sale
shall be conclusively deemed to have been made in a commercially reasonable
manner and that Agent shall have no obligation either to engage in public sales
or to delay the sale of any Pledged Collateral for the period of time necessary
to permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would, or should, agree to so register it.  Pledgor further
acknowledges the impossibility of ascertaining the amount of damages which would
be suffered by Agent by reason of the failure by Pledgor to perform any of the
covenants contained in this Section and, consequently, agrees that, if Pledgor
shall fail to perform any of such covenants, it shall pay, as liquidated damages
and not as a penalty, an amount equal to the value of the Pledged Collateral on
the date Agent shall demand compliance with this Section.

          (d) If Agent determines to exercise its right to sell any or all of
the Pledged Collateral, upon written request, Pledgor shall and shall cause each
issuer of any Pledged Shares to be sold hereunder from time to time to furnish
to Agent all such information as Agent may request in order to determine the
number of shares and other

                                     -11-
<PAGE>
 
instruments included in the Pledged Collateral which may be sold by Agent in
exempt transactions under the Securities Act and the rules and regulations of
the Securities and Exchange Commission thereunder, as the same are from time to
time in effect.

          SECTION 12.  INDEMNITY AND EXPENSES.
                       ---------------------- 

          (a) Pledgor agrees to indemnify Agent and each Bank from and against
any and all claims, losses and liabilities in any way relating to, growing out
of or resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses or liabilities result solely from Agent's or such
Bank's gross negligence or willful misconduct as finally determined by a court
of competent jurisdiction.

          (b) Pledgor shall pay to Agent upon demand the amount of any and all
costs and expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, that Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Agent
hereunder, or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

          SECTION 13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
                       -----------------------------------------------      
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the payment in full of all
Secured Obligations, (b) be binding upon Pledgor, its successors and assigns,
and (c) inure, together with the rights and remedies of Agent hereunder, to the

the generality of the foregoing clause (c), any Bank may, subject to the terms
of the Credit Agreement, assign or otherwise transfer its interest in the Credit
Agreement in whole or in part to any other Person, and such other Person shall
thereupon become vested with all benefits in respect thereof granted to Banks
herein or otherwise.  Upon the payment in full of all Secured Obligations, the
security interest granted hereby shall terminate and all rights to the Pledged
Collateral shall revert to Pledgor.  Upon any such termination Agent will, at
Pledgor's expense, execute and deliver to Pledgor such documents as Pledgor
shall reasonably request to evidence such termination and Pledgor shall be
entitled to the return, upon its request and at its expense, against receipt and
without recourse to Agent, of such of the Pledged Collateral as shall not have
been sold or otherwise applied pursuant to the terms hereof.

Agreement, no amendment, modification, termination or waiver of any provision of
this Agreement, and no consent to any departure by Pledgor therefrom, shall in
any event be effective unless the same shall be in writing and signed by Agent
and, in the
                                     -12-

case of any such amendment or modification, by Pledgor. Any such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which it was given.

                       -------

          SECTION 16.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                       -----------------------------------------------------  
No failure or delay on the part of Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 17.  SEVERABILITY.  In case any provision in or obligation

jurisdiction in any action against Pledgor in any such court and to be otherwise
effective and binding service in every respect.  Nothing herein shall affect the
right to serve process in any other manner permitted by law or shall limit the
right of Agent to bring proceedings against Pledgor in the courts of any other
jurisdiction.

          (a) any right to require Agent or any Bank, as a condition of payment

of the Secured Obligations or any agreement or instrument relating thereto or by
reason of the cessation of the liability of Company from any cause other than
payment in full of the Secured Obligations;

          (c) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;

          (d) any defense based upon Agent's or any Bank's errors or omissions
in the administration of the Secured Obligations, except behavior which amounts
to bad faith;

          (e) (i) any principles or provisions of law, statutory or otherwise,
which are or might be in conflict with the terms of this Pledge Agreement and
any legal or equitable discharge of such Pledgor's obligations hereunder, (ii)
the benefit of any statute of limitations affecting Pledgor's liability

          SECTION 23.  CERTAIN CALIFORNIA LAW WAIVERS.  As used in this Section
                       ------------------------------                          
23, any reference to "the principal" includes Company, and any reference to "the
creditor" includes Agent and each Bank.  In accordance with Section 2856 of the
California Civil Code:

          (a) Pledgor agrees (i) to waive any and all rights of subrogation and
reimbursement against Company or against any collateral or security granted by
Company for any of the Secured Obligations and (ii) to withhold the exercise of
any and all rights of subrogation, reimbursement and contribution against
Company, against any other guarantor of any of the Secured Obligations and
against any collateral or security granted by any such other guarantor for any
of the Secured Obligations until the Secured Obligations shall have been paid in
full and all letters of credit issued under the Credit Agreement and the other
Loan Documents shall have expired or been cancelled, all as more fully set forth
in Section 24;

          (b) Pledgor waives any and all other rights and defenses available to
such Pledgor by reason of Sections 2787 to 2855, inclusive, 2899 and 3433 of the
California Civil Code, including without limitation any and all rights or
defenses Pledgor may have by reason of protection afforded to the principal with
respect to any of the Secured Obligations, or to any other guarantor of any of
the Secured Obligations with respect to any of such guarantor's obligations
under its guaranty, in either case pursuant to the antideficiency or other laws
of the State of California limiting or discharging the principal's indebtedness
or such guarantor's obligations, including without limitation Section 580a,
580b, 580d, or 726 of the California Code of Civil Procedure; and

          (c) Pledgor waives all rights and defenses arising out of an election
of remedies by the creditor, even though that election of remedies, such as a
nonjudicial foreclosure with respect to security for any Secured Obligation, has
destroyed Pledgor's rights of subrogation and reimbursement against the
principal by the operation of Section 580d of the Code of Civil Procedure or
otherwise; and even though that election of remedies by the creditor, such as
nonjudicial foreclosure with respect to security for an obligation of any other
guarantor (including any other Pledgor) of any of the Secured Obligations, has
destroyed Pledgor's rights of contribution against such other guarantor.

No other provision of this Pledge Agreement shall be construed as limiting the
generality of any of the covenants and waivers set forth in this Section 23.

                                     -16-

          SECTION 24.  PLEDGOR'S RIGHTS OF SUBROGATION, CONTRIBUTION, ETC.
                       -------------------------------------------------- 
Pledgor hereby waives any claim, right or remedy, direct or indirect, that
Pledgor now has or may hereafter have against Company or any of its assets in
connection with this Pledge Agreement or the performance by Pledgor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute (including without limitation under
California Civil Code Section 2847, 2848 or 2849), under common law or otherwise
and including without limitation (a) any right of subrogation, reimbursement or
indemnification that Pledgor now has or may hereafter have against Company, (b)
any right to enforce, or to participate in, any claim, right or remedy that
Agent or any Bank now has or may hereafter have against Company, and (c) any
benefit of, and any right to participate in, any collateral or security now or
hereafter held by Agent or any Bank.  In addition, until the Secured Obligations
shall have been indefeasibly paid in full and all letters of credit issued under
the Credit Agreement shall have expired or been cancelled, Pledgor shall
withhold exercise of any right of contribution Pledgor may have against any
other guarantor of the Secured Obligations (including without limitation any
such right of contribution under California Civil Code Section 2848).  Pledgor
further agrees that, to the extent the waiver or agreement to withhold the
exercise of its rights of subrogation, reimbursement, indemnification and
contribution as set forth herein is found by a court of competent jurisdiction
to be void or voidable for any reason, any rights of subrogation, reimbursement
or indemnification Pledgor may have against Company or against any collateral or
security, and any rights of contribution Pledgor may have against any such other
guarantor, shall be junior and subordinate to any rights Agent or any Bank may
have against Company, to all right, title and interest Agent or any Bank may
have in any such collateral or security, and to any right Agent or any Bank may
have against such other guarantor.  If any amount shall be paid to Pledgor on
account of any such subrogation, reimbursement, indemnification or contribution
rights at any time when all Secured Obligations shall not have been paid in
full, such amount shall be held in trust for Agent on behalf of Banks and shall
forthwith be paid over to Agent for the benefit of Banks to be credited and
applied against the Secured Obligations, whether matured or unmatured, in
accordance with the terms hereof.

          SECTION 25.  COUNTERPARTS.  This Agreement may be executed in one or
                       ------------                                           
more counterparts and by different parties hereto in separate counterparts, each
of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.

consensual rights which it may be entitled to exercise pursuant to Section

entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) each Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Agent all such proxies, dividend payment orders and other instruments as Agent
may from time to time reasonably request and (ii) without limiting the effect of
the immediately preceding clause (i), each Pledgor hereby grants to Agent an
irrevocable proxy to vote the Pledged Collateral and to exercise all other
rights, powers, privileges and remedies to which a holder of the Pledged
Collateral would be entitled (including, without limitation, giving or

not impose any duty upon it to exercise any such powers.  Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Agent shall have no duty as to any Pledged Collateral, it being understood that
Agent shall have no responsibility for (a) ascertaining or taking action with

and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Agent accords
its own property consisting of negotiable securities.

          SECTION 11.  REMEDIES.
                       -------- 

          (a) If any Event of Default shall have occurred and be continuing,
Agent may, subject to the terms of the Credit Agreement, exercise in respect of
the Pledged Collateral, in addition to all other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party on default under the Uniform Commercial Code as in effect in any
relevant jurisdiction (the "CODE") (whether or not the Code applies to the
affected Pledged Collateral), and Agent may also in its sole discretion, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale, at any exchange or
broker's board or at any of Agent's offices or elsewhere, for cash, on credit or
for future delivery, at such time or times and at such price or prices and upon
such other terms as Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged Collateral.  Agent
or any Bank may be the purchaser of any or all of the Pledged Collateral at any
such sale and Agent, as agent for and representative of the Banks, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at any such
public sale, to use and apply any of the Secured Obligations as a credit on
account of the purchase price for any Pledged Collateral payable by Agent at
such sale.  Each purchaser at any such sale shall hold the property sold
absolutely free from any claim or right on the part of each Pledgor, and each
Pledgor hereby waives (to the extent permitted by applicable law) all rights of
redemption, stay and/or appraisal which it now has or may at any time in the
future have under any rule of law or statute now existing or hereafter enacted.
Each Pledgor agrees that, to the extent notice of sale shall be required by law,
at least ten days' notice to each Pledgor of the time and place of any public
sale or the time after which any private sale is to be made shall constitute
reasonable notification.  Agent shall not be obligated to make any sale of
Pledged Collateral regardless of notice of sale having been given.  Agent may
adjourn any public or private sale from time to time by announcement at the time
and place fixed therefor, and such sale may, without further notice, be made at
the time and place to which it was so adjourned.  To the extent permitted by
applicable law, each Pledgor hereby waives any claims against Agent arising by
reason of the fact that the price at which any Pledged Collateral may have been
sold at any such private sale was less than the price which might have been
obtained at a public sale, even if Agent accepts the first offer received and
does not offer such Pledged Collateral to more than one offeree.  If the
proceeds of any sale or

                                     -10-
<PAGE>
 
other disposition of the Pledged Collateral are insufficient to pay all of the
Secured Obligations, each Pledgor shall be liable for the deficiency and the
reasonable fees of any attorneys employed by Agent to collect such deficiency.

          (b) Any cash held by Agent as Pledged Collateral and all cash proceeds
received by Agent in respect of any sale of, collection from, or other
realization upon all or any part of the Pledged Collateral may, in the
discretion of Agent, be held by Agent as collateral for, and/or then or at any
time thereafter applied (after payment of any amounts payable to Agent pursuant
to Section 12(b)) in whole or in part by Agent against all or any part of the
Secured Obligations in such order as Agent shall elect.  Any surplus of such
cash or cash proceeds held by Agent and remaining after payment in full of all
the Secured Obligations shall be paid over to each Pledgor or to whosoever may
be lawfully entitled to receive such surplus.

          (c) Each Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended from time to time (the
"SECURITIES ACT"), and applicable state securities laws, Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under the
Securities Act and/or such state securities laws, to conduct such sales as
private, not public, sales and to limit purchasers to a restricted group who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  each Pledgor acknowledges and agrees that any such private sales may
be at prices and on terms less favorable than those obtainable through a public
sale without such restrictions (including, without limitation, a public offering
made pursuant to an effective registration statement under the Securities Act)
and, notwithstanding such circumstances, each Pledgor agrees that any such
private sale shall be conclusively deemed to have been made in a commercially
reasonable manner and that Agent shall have no obligation either to engage in
public sales or to delay the sale of any Pledged Collateral for the period of
time necessary to permit the issuer thereof to register it for a form of public
sale requiring registration under the Securities Act or under applicable state
securities laws, even if such issuer would, or should, agree to so register it.
each Pledgor further acknowledges the impossibility of ascertaining the amount
of damages which would be suffered by Agent by reason of the failure by each
Pledgor to perform any of the covenants contained in this Section and,
consequently, agrees that, if each Pledgor shall fail to perform any of such
covenants, it shall pay, as liquidated damages and not as a penalty, an amount
equal to the value of the Pledged Collateral on the date Agent shall demand
compliance with this Section.

          (d) If Agent determines to exercise its right to sell any or all of
the Pledged Collateral, upon written request, each Pledgor shall and shall cause
each issuer of any Pledged Interests to be sold hereunder from time to time to
furnish to Agent all such information as Agent may request in order to determine
the number of interests

                                     -11-
<PAGE>
 
and other instruments included in the Pledged Collateral which may be sold by
Agent in exempt transactions under the Securities Act and the rules and
regulations of the Securities and Exchange Commission thereunder, as the same
are from time to time in effect.

          SECTION 12.  INDEMNITY AND EXPENSES.
                       ---------------------- 

          (a) Each Pledgor agrees to indemnify Agent and each Bank from and
against any and all claims, losses and liabilities in any way relating to,
growing out of or resulting from this Agreement and the transactions
contemplated hereby (including, without limitation, enforcement of this
Agreement), except to the extent such claims, losses or liabilities result
solely from Agent's or such Bank's gross negligence or willful misconduct as
finally determined by a court of competent jurisdiction.

          (b) Each Pledgor shall pay to Agent upon demand the amount of any and
all costs and expenses, including the reasonable fees and expenses of its
counsel and of any experts and agents, that Agent may incur in connection with
(i) the administration of this Agreement, (ii) the custody or preservation of,
or the sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Agent
hereunder, or (iv) the failure by each Pledgor to perform or observe any of the
provisions hereof.

          SECTION 13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
                       -----------------------------------------------      
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the payment in full of all
Secured Obligations, (b) be binding upon each Pledgor, its successors and
assigns, and (c) inure, together with the rights and remedies of Agent
hereunder, to the benefit of Agent and its successors, transferees and assigns.
Without limiting the generality of the foregoing clause (c), any Bank may,
subject to the terms of the Credit Agreement, assign or otherwise transfer its
interest in the Credit Agreement in whole or in part to any other Person, and
such other Person shall thereupon become vested with all benefits in respect
thereof granted to Banks herein or otherwise.  Upon the payment in full of all
Secured Obligations, the security interest granted hereby shall terminate and
all rights to the Pledged Collateral shall revert to each Pledgor.  Upon any
such termination Agent will, at each Pledgor's expense, execute and deliver to
each Pledgor such documents as each Pledgor shall reasonably request to evidence
such termination and each Pledgor shall be entitled to the return, upon its
request and at its expense, against receipt and without recourse to Agent, of
such of the Pledged Collateral as shall not have been sold or otherwise applied
pursuant to the terms hereof.

          SECTION 14.  AMENDMENTS; ETC.  Subject to Section 11.01 of the Credit
                       ---------------                                         
Agreement, no amendment, modification, termination or waiver of any provision of
this Agreement, and no consent to any departure by each Pledgor

                                     -12-
<PAGE>
 
therefrom, shall in any event be effective unless the same shall be in writing
and signed by Agent and, in the case of any such amendment or modification, by
each Pledgor. Any such waiver or consent shall be effective only in the specific
instance and for the specific purpose for which it was given.

          SECTION 15.  NOTICES.  Any notice or other communication herein
                       -------

either party, such other address as shall be designated by such party in a
written notice delivered to the other party hereto.

          SECTION 16.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                       -----------------------------------------------------  
No failure or delay on the part of Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 17.  SEVERABILITY.  In case any provision in or obligation
                       ------------                                         
under this Agreement shall be invalid, illegal or unenforceable in any
jurisdiction, the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby.

          SECTION 19.  GOVERNING LAW; TERMS.  THIS AGREEMENT AND THE RIGHTS AND
                       --------------------                                    
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF
CALIFORNIA, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO THE EXTENT
THAT THE CODE PROVIDES THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST

                       ----------------------------------------------      
JUDICIAL PROCEEDINGS BROUGHT AGAINST EACH PLEDGOR ARISING OUT OF OR RELATING TO
THIS AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE
UNITED STATES FOR THE CENTRAL DISTRICT OF CALIFORNIA, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT EACH PLEDGOR ACCEPTS FOR ITSELF AND IN CONNECTION

all process in any such proceeding in any such court may be made by registered
or certified mail, return receipt requested, to each Pledgor at its address
provided in Section 15, such service being hereby acknowledged by each Pledgor
to be sufficient for personal jurisdiction in any action against each Pledgor in
any such court and to be otherwise effective and binding service in every
respect.  Nothing herein shall affect the right to serve process in any other
manner permitted by law or shall limit the right of Agent to bring proceedings
against each Pledgor in the courts of any other jurisdiction.

          SECTION 21.  WAIVER OF JURY TRIAL.  EACH PLEDGOR AND AGENT HEREBY
                       --------------------                                
AGREE TO WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF

intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach of duty claims, and all
other common law and statutory claims. Each Pledgor and Agent each acknowledge

into a business relationship, that each Pledgor and Agent have already relied on
this waiver in entering into this Agreement and that each will continue to rely
on this waiver in their related future dealings.  Each Pledgor and Agent further
warrant and represent that each has reviewed this waiver with its legal counsel,
and that each knowingly and voluntarily waives its jury trial rights following
consultation with legal counsel.  THIS WAIVER IS IRREVOCABLE, MEANING THAT IT
MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO
ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT.

                                     -14-

In the event of litigation, this Agreement may be filed as a written consent to
a trial by the court.

          SECTION 22.  WAIVERS BY PLEDGORS.  Each Pledgor hereby waives, for the
                       -------------------                                      
benefit of Banks and Agent:

          (a) any right to require Agent or any Bank, as a condition of payment
or performance by such Pledgor, to (i) proceed against Company, any other
guarantor (including any other Pledgor) of the Secured Obligations or any other
Person, (ii) proceed against or exhaust any security held from Company, any such
other guarantor (including any other Pledgor) or any other Person, (iii) proceed
against or have resort to any balance of any deposit account or credit on the
books of Agent or any Bank in favor of Company or any other Person, or (iv)
pursue any other remedy in the power of Agent or any Bank whatsoever;

          (b) any defense arising by reason of the incapacity, lack of authority
or any disability or other defense of Company including, without limitation, any
defense based on or arising out of the lack of validity or the unenforceability
of the Secured Obligations or any agreement or instrument relating thereto or by
reason of the cessation of the liability of Company from any cause other than
payment in full of the Secured Obligations;

          (c) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal;

          (d) any defense based upon Agent's or any Bank's errors or omissions
in the administration of the Secured Obligations, except behavior which amounts
to bad faith;

          (e) (i) any principles or provisions of law, statutory or otherwise,
which are or might be in conflict with the terms of this Pledge Agreement and
any legal or equitable discharge of such Pledgor's obligations hereunder, (ii)
the benefit of any statute of limitations affecting such Pledgor's liability
hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments
and counterclaims, and (iv) promptness, diligence and any requirement that Agent
or any Bank protect, secure, perfect or insure any security interest or lien or
any property subject thereto;

          (f) notices, demands, presentments, protests, notices of protest,
notices of dishonor and notices of any action or inaction, including acceptance
of this Pledge Agreement, notices of default under the Credit Agreement, the
Loan Documents or any agreement or instrument related thereto, notices of any
renewal, extension or

                                     -15-
<PAGE>
 
modification of the Secured Obligations or any agreement related thereto,
notices of any extension of credit to Company and any right to consent to any
thereof; and

          (g) any defenses or benefits that may be derived from or afforded by
law which limit the liability of or exonerate guarantors or sureties, or which
may conflict with the terms of this Pledge Agreement.

          SECTION 23.  CERTAIN CALIFORNIA LAW WAIVERS.  As used in this Section
                       ------------------------------                          
23, any reference to "the principal" includes Company, and any reference to "the
creditor" includes Agent and each Bank.  In accordance with Section 2856 of the
California Civil Code:

          (a) each Pledgor agrees (i) to waive any and all rights of subrogation
and reimbursement against Company or against any collateral or security granted
by Company for any of the Secured Obligations and (ii) to withhold the exercise
of any and all rights of subrogation, reimbursement and contribution against
Company, against any other guarantor of any of the Secured Obligations and
against any collateral or security granted by any such other guarantor for any
of the Secured Obligations until the Secured Obligations shall have been paid in
full and all letters of credit issued under the Credit Agreement and the other
Loan Documents shall have expired or been cancelled, all as more fully set forth
in subsection 22(c);

          (b) each Pledgor waives any and all other rights and defenses
available to such Pledgor by reason of Sections 2787 to 2855, inclusive, 2899
and 3433 of the California Civil Code, including without limitation any and all
rights or defenses such Pledgor may have by reason of protection afforded to the
principal with respect to any of the Secured Obligations, or to any other
guarantor (including any other Pledgor) of any of the Secured Obligations with
respect to any of such guarantor's obligations under its guaranty, in either
case pursuant to the antideficiency or other laws of the State of California
limiting or discharging the principal's indebtedness or such guarantor's
obligations, including without limitation Section 580a, 580b, 580d, or 726 of
the California Code of Civil Procedure; and

          (c) each Pledgor waives all rights and defenses arising out of an
election of remedies by the creditor, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for any Secured
Obligation, has destroyed such Pledgor's rights of subrogation and reimbursement
against the principal by the operation of Section 580d of the Code of Civil
Procedure or otherwise; and even though that election of remedies by the
creditor, such as nonjudicial foreclosure with respect to security for an
obligation of any other guarantor (including any other Pledgor) of any of the
Secured Obligations, has destroyed such Pledgor's rights of contribution against
such other guarantor.

                                     -16-
<PAGE>
 
No other provision of this Pledge Agreement shall be construed as limiting the
generality of any of the covenants and waivers set forth in this Section 23.

          SECTION 24.  PLEDGORS' RIGHTS OF SUBROGATION, CONTRIBUTION, ETC. Each
                       --------------------------------------------------      
Pledgor hereby waives any claim, right or remedy, direct or indirect, that such
Pledgor now has or may hereafter have against Company or any of its assets in
connection with this Pledge Agreement or the performance by such Pledgor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute (including without limitation under
California Civil Code Section 2847, 2848 or 2849), under common law or otherwise
and including without limitation (a) any right of subrogation, reimbursement or
indemnification that such Pledgor now has or may hereafter have against Company,
(b) any right to enforce, or to participate in, any claim, right or remedy that
Agent or any Bank now has or may hereafter have against Company, and (c) any
benefit of, and any right to participate in, any collateral or security now or
hereafter held by Agent or any Bank. In addition, until the Secured Obligations
shall have been indefeasibly paid in full and all letters of credit issued under
the Credit Agreement shall have expired or been cancelled, each Pledgor shall
withhold exercise of any right of contribution such Pledgor may have against any
other guarantor (including any other Pledgor) of the Secured Obligations
(including without limitation any such right of contribution under California
Civil Code Section 2848).  Each Pledgor further agrees that, to the extent the
waiver or agreement to withhold the exercise of its rights of subrogation,
reimbursement, indemnification and contribution as set forth herein is found by
a court of competent jurisdiction to be void or voidable for any reason, any
rights of subrogation, reimbursement or indemnification such Pledgor may have
against Company or against any collateral or security, and any rights of
contribution such Pledgor may have against any such other guarantor, shall be
junior and subordinate to any rights Agent or any Bank may have against Company,
to all right, title and interest Agent or any Bank may have in any such
collateral or security, and to any right Agent or any Bank may have against such
other guarantor.  If any amount shall be paid to any Pledgor on account of any
such subrogation, reimbursement, indemnification or contribution rights at any
time when all Secured Obligations shall not have been paid in full, such amount
shall be held in trust for Agent on behalf of Banks and shall forthwith be paid
over to Agent for the benefit of Banks to be credited and applied against the
Secured Obligations, whether matured or unmatured, in accordance with the terms
hereof.

          SECTION 25.  COUNTERPARTS.  This Agreement may be executed in one or
                       ------------                                           
more counterparts and by different parties hereto in separate counterparts, each
of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single   counterpart so that all signature pages are physically attached to
the same document.

                                     -17-

         IN WITNESS WHEREOF, each Pledgor and Agent have caused this Agreement
to be duly executed and delivered by their respective officers thereunto duly
authorized as of the date first written above.

          B.   As a condition precedent to the effectiveness of the Existing

and assigned certain of its collateral as set forth therein to Agent for the

(the "PLEDGED SHARES") described in Schedule I annexed hereto and issued by the
                                    ----------

          D.   Company has agreed to amend and restate the Existing Credit

Agreement. Except as otherwise defined herein, all other capitalized terms used
herein shall have the respective meanings given to such terms in the Credit
Agreement.

          E.   It is a condition precedent to the effectiveness of the Credit
Agreement that the Existing Pledge Agreement be amended and restated pursuant to

limiting the generality of the foregoing, Pledgor will:  (i) execute and file
such financing or continuation statements, or amendments thereto, and such other
instruments or notices (including, without limitation, powers with respect to,
or other endorsements or instruments necessary to effect the assignment or other
transfer of, any of the Pledged Collateral), as may be 

                                      -6-
<PAGE>
 
necessary or desirable, or as Agent may request, in order to perfect and
preserve the security interests granted or purported to be granted hereby and
(ii) at Agent's request, appear in and defend any action or proceeding that may
affect Pledgor's title to or Agent's security interest in all or any part of the
Pledged Collateral.

          (b) Pledgor further agrees that it will, upon obtaining any additional
securities required to be pledged hereunder as provided in Section 5(b),
promptly (and in any event within five Business Days) deliver to Agent a Pledge
Amendment, duly executed by Pledgor, in substantially the form of Schedule IV
                                                                  -----------
annexed hereto (a "PLEDGE AMENDMENT"), in respect of the additional Pledged
Interests to be pledged pursuant to this Agreement.  Pledgor hereby authorizes
Agent to attach each Pledge Amendment to this Agreement and agrees that all
Pledged Interests listed on any Pledge Amendment delivered to Agent shall for
all purposes hereunder be considered Pledged Collateral; provided, however, that
                                                         --------  -------      
the failure of Pledgor to execute a Pledge Amendment with respect to any
additional Pledged Interests pledged pursuant to this Agreement shall not impair
the security interest of Agent therein or otherwise adversely affect the rights
and remedies of Agent hereunder with respect thereto.

          SECTION 7.  VOTING RIGHTS; DIVIDENDS; ETC.
                      ------------------------------

          (a) So long as no Event of Default shall have occurred and be
continuing:

          (i) Pledgor shall be entitled to exercise any and all voting and other
consensual rights pertaining to the Pledged Collateral or any part thereof for
any purpose not inconsistent with the terms of this Agreement or the Credit
Agreement; provided, however, that Pledgor shall not exercise or refrain from
           --------  -------                                                 
exercising any such right if Agent shall have notified Pledgor that, in Agent's
judgment, such action would have a material adverse effect on the value of the
Pledged Collateral or any part thereof;

          (ii) Pledgor shall be entitled to receive and retain, and to utilize
free and clear of the lien of this Agreement, any and all dividends and interest
paid in respect of the Pledged Collateral; provided, however, that any and all
                                           --------  -------                  

               (A) dividends and interest paid or payable other than in cash in
respect of, and instruments and other property received, receivable or otherwise
distributed in respect of, or in exchange for, any Pledged Collateral,

               (B) dividends and other distributions paid or payable in cash in
respect of any Pledged Collateral in connection with (x) a partial or total
liquidation or dissolution, (y) a reduction of capital, capital surplus or paid-
in-surplus or (z) a quasi-reorganization, and

                                      -7-
<PAGE>
 
               (C) cash paid, payable or otherwise distributed in respect of
principal or in redemption of or in exchange for any Pledged Collateral,
shall be, and shall forthwith be delivered to Agent to hold as, Pledged
Collateral and shall, if received by Pledgor, be received in trust for the
benefit of Agent, be segregated from the other property or funds of Pledgor and
be forthwith delivered to Agent as Pledged Collateral in the same form as so
received (with all necessary endorsements); and

          (iii)  Agent shall promptly execute and deliver (or cause to be
executed and delivered) to Pledgor all such proxies, dividend payment orders and
other instruments as Pledgor may from time to time reasonably request for the
purpose of enabling Pledgor to exercise the voting and other consensual rights
which it is entitled to exercise pursuant to paragraph (i) above and to receive
the dividends, principal or interest payments which it is authorized to receive
and retain pursuant to paragraph (ii) above.

     (b) Upon the occurrence and during the continuation of any Default or
Event of Default:

          (i) upon written notice from Agent to Pledgor, all rights of Pledgor
to exercise the voting and other consensual rights which it would otherwise be
entitled to exercise pursuant to Section 7(a)(i) shall cease, and all such
rights shall thereupon become vested in Agent who shall thereupon have the sole
right to exercise such voting and other consensual rights;

          (ii) all rights of Pledgor to receive the dividends and interest
payments which it would otherwise be authorized to receive and retain pursuant
to Section 7(a)(ii) shall cease, and all such rights shall thereupon become
vested in Agent who shall thereupon have the sole right to receive and hold as
Pledged Collateral such dividends and interest payments; and

         (iii) all dividends, principal and interest payments which
are received by Pledgor contrary to the provisions of paragraph (ii) of this
Section 7(b) shall be received in trust for the benefit of Agent, shall be
segregated from other funds of Pledgor and shall forthwith be paid over to Agent
as Pledged Collateral in the same form as so received (with any necessary
endorsements).

     (c) In order to permit Agent to exercise the voting and other
consensual rights which it may be entitled to exercise pursuant to Section
7(b)(i) and to receive all dividends and other distributions which it may be
entitled to receive under Section 7(a)(ii) or Section 7(b)(ii), (i) Pledgor
shall promptly execute and deliver (or cause to be executed and delivered) to
Agent all such proxies, dividend payment orders 

                                      -8-
<PAGE>
 
and other instruments as Agent may from time to time reasonably request and (ii)
without limiting the effect of the immediately preceding clause (i), Pledgor
hereby grants to Agent an irrevocable proxy to vote the Pledged Collateral and
to exercise all other rights, powers, privileges and remedies to which a holder
of the Pledged Collateral would be entitled (including, without limitation,
giving or withholding written consents of shareholders, calling special meetings
of shareholders and voting at such meetings), which proxy shall be effective,
automatically and without the necessity of any action (including any transfer of
any Pledged Collateral on the record books of the issuer thereof) by any other
Person (including the issuer of the Pledged Collateral or any officer or agent
thereof), upon the occurrence of an Event of Default or Default and which proxy
shall only terminate upon the payment in full of the Secured Obligations.

          SECTION 8.  AGENT APPOINTED ATTORNEY-IN-FACT.  Pledgor hereby
                      --------------------------------                 
irrevocably appoints Agent as Pledgor's attorney-in-fact, with full authority in
the place and stead of Pledgor and in the name of Pledgor, Agent or otherwise,
from time to time in Agent's discretion to take any action and to execute any
instrument that Agent may deem necessary or advisable to accomplish the purposes
of this Agreement, including without limitation:

          (a) to file one or more financing or continuation statements, or
amendments thereto, or powers or other endorsements or instruments of transfer
or assignments in blank, relative to all or any part of the Pledged Collateral,
or to enter into agreements with Agent and any securities intermediaries
described in Section 1 relating to any Pledged Collateral to protect Agent's
security interest therein, in form and substance satisfactory to Agent, in each
case without the signature of Pledgor;

          (b) after the occurrence and during the continuation of any Event of
Default, to ask, demand, collect, sue for, recover, compound, receive and give
acquittance and receipts for moneys due and to become due under or in respect of
any of the Pledged Collateral;

          (c) after the occurrence and during the continuation of any Event of
Default, to receive, endorse and collect any instruments made payable to Pledgor
representing any dividend, principal or interest payment or other distribution
in respect of the Pledged Collateral or any part thereof and to give full
discharge for the same; and

          (d) after the occurrence and during the continuation of any Event of
Default, to file any claims or take any action or institute any proceedings that
Agent may deem necessary or desirable for the collection of any of the Pledged
Collateral or otherwise to enforce the rights of Agent with respect to any of
the Pledged Collateral.

                                      -9-
<PAGE>
 
          SECTION 9.  AGENT MAY PERFORM.  If Pledgor fails to perform any
                      -----------------                                  
agreement contained herein, Agent may itself perform, or cause performance of,
such agreement, and the expenses of Agent incurred in connection therewith shall
be payable by Pledgor under Section 12(b).

          SECTION 10.  STANDARD OF CARE.  The powers conferred on Agent
                       ----------------                                
hereunder are solely to protect its interest in the Pledged Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for the
exercise of reasonable care in the custody of any Pledged Collateral in its
possession and the accounting for moneys actually received by it hereunder,
Agent shall have no duty as to any Pledged Collateral, it being understood that
Agent shall have no responsibility for (a) ascertaining or taking action with
respect to calls, conversions, exchanges, maturities, tenders or other matters
relating to any Pledged Collateral, whether or not Agent has or is deemed to
have knowledge of such matters, (b) taking any necessary steps (other than steps
taken in accordance with the standard of care set forth above to maintain
possession of the Pledged Collateral) to preserve rights against any parties
with respect to any Pledged Collateral, (c) taking any necessary steps to
collect or realize upon the Secured Obligations or any guarantee therefor, or
any part thereof, or any of the Pledged Collateral, or (d) initiating any action
to protect the Pledged Collateral against the possibility of a decline in market
value.  Agent shall be deemed to have exercised reasonable care in the custody
and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Agent accords
its own property consisting of negotiable securities.

          SECTION 11.  REMEDIES.
                       -------- 

          (a) If any Event of Default shall have occurred and be continuing,
Agent may, subject to the terms of the Credit Agreement, exercise in respect of
the Pledged Collateral, in addition to all other rights and remedies provided
for herein or otherwise available to it, all the rights and remedies of a
secured party on default under the Uniform Commercial Code as in effect in any
relevant jurisdiction (the "CODE") (whether or not the Code applies to the
affected Pledged Collateral), and Agent may also in its sole discretion, without
notice except as specified below, sell the Pledged Collateral or any part
thereof in one or more parcels at public or private sale, at any exchange or
broker's board or at any of Agent's offices or elsewhere, for cash, on credit or
for future delivery, at such time or times and at such price or prices and upon
such other terms as Agent may deem commercially reasonable, irrespective of the
impact of any such sales on the market price of the Pledged Collateral.  Agent
or any Bank may be the purchaser of any or all of the Pledged Collateral at any
such sale and Agent, as agent for and representative of the Banks, shall be
entitled, for the purpose of bidding and making settlement or payment of the
purchase price for all or any portion of the Pledged Collateral sold at any such
public sale, to use and apply any of the Secured Obligations as a credit on
account of the purchase price for any Pledged 

                                     -10-
<PAGE>
 
Collateral payable by Agent at such sale. Each purchaser at any such sale shall
hold the property sold absolutely free from any claim or right on the part of
Pledgor, and Pledgor hereby waives (to the extent permitted by applicable law)
all rights of redemption, stay and/or appraisal which it now has or may at any
time in the future have under any rule of law or statute now existing or
hereafter enacted. Pledgor agrees that, to the extent notice of sale shall be
required by law, at least ten days' notice to Pledgor of the time and place of
any public sale or the time after which any private sale is to be made shall
constitute reasonable notification. Agent shall not be obligated to make any
sale of Pledged Collateral regardless of notice of sale having been given. Agent
may adjourn any public or private sale from time to time by announcement at the
time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned. To the extent permitted
by applicable law, Pledgor hereby waives any claims against Agent arising by
reason of the fact that the price at which any Pledged Collateral may have been
sold at any such private sale was less than the price which might have been
obtained at a public sale, even if Agent accepts the first offer received and
does not offer such Pledged Collateral to more than one offeree. If the proceeds
of any sale or other disposition of the Pledged Collateral are insufficient to
pay all of the Secured Obligations, Pledgor shall be liable for the deficiency
and the reasonable fees of any attorneys employed by Agent to collect such
deficiency.

          (b) Any cash held by Agent as Pledged Collateral and all cash proceeds
received by Agent in respect of any sale of, collection from, or other
realization upon all or any part of the Pledged Collateral may, in the
discretion of Agent, be held by Agent as collateral for, and/or then or at any
time thereafter applied (after payment of any amounts payable to Agent pursuant
to Section 12(b)) in whole or in part by Agent against all or any part of the
Secured Obligations in such order as Agent shall elect.  Any surplus of such
cash or cash proceeds held by Agent and remaining after payment in full of all
the Secured Obligations shall be paid over to Pledgor or to whosoever may be
lawfully entitled to receive such surplus.

          (c) Pledgor recognizes that, by reason of certain prohibitions
contained in the Securities Act of 1933, as amended from time to time (the
"SECURITIES ACT"), and applicable state securities laws, Agent may be compelled,
with respect to any sale of all or any part of the Pledged Collateral conducted
without prior registration or qualification of such Pledged Collateral under the
Securities Act and/or such state securities laws, to conduct such sales as
private, not public, sales and to limit purchasers to a restricted group who
will agree, among other things, to acquire the Pledged Collateral for their own
account, for investment and not with a view to the distribution or resale
thereof.  Pledgor acknowledges and agrees that any such private sales may be at
prices and on terms less favorable than those obtainable through a public sale
without such restrictions (including, without limitation, a public offering made
pursuant to an effective registration statement under the Securities Act) and,

                                     -11-
<PAGE>
 
notwithstanding such circumstances, Pledgor agrees that any such private sale
shall be conclusively deemed to have been made in a commercially reasonable
manner and that Agent shall have no obligation either to engage in public sales
or to delay the sale of any Pledged Collateral for the period of time necessary
to permit the issuer thereof to register it for a form of public sale requiring
registration under the Securities Act or under applicable state securities laws,
even if such issuer would, or should, agree to so register it.  Pledgor further
acknowledges the impossibility of ascertaining the amount of damages which would
be suffered by Agent by reason of the failure by Pledgor to perform any of the
covenants contained in this Section and, consequently, agrees that, if Pledgor
shall fail to perform any of such covenants, it shall pay, as liquidated damages
and not as a penalty, an amount equal to the value of the Pledged Collateral on
the date Agent shall demand compliance with this Section.

          (d) If Agent determines to exercise its right to sell any or all of
the Pledged Collateral, upon written request, Pledgor shall and shall cause each
issuer of any Pledged Interests to be sold hereunder from time to time to
furnish to Agent all such information as Agent may request in order to determine
the number of interests and other instruments included in the Pledged Collateral
which may be sold by Agent in exempt transactions under the Securities Act and
the rules and regulations of the Securities and Exchange Commission thereunder,
as the same are from time to time in effect.

          SECTION 12.  INDEMNITY AND EXPENSES.
                       ---------------------- 

          (a) Pledgor agrees to indemnify Agent and each Bank from and against
any and all claims, losses and liabilities in any way relating to, growing out
of or resulting from this Agreement and the transactions contemplated hereby
(including, without limitation, enforcement of this Agreement), except to the
extent such claims, losses or liabilities result solely from Agent's or such
Bank's gross negligence or willful misconduct as finally determined by a court
of competent jurisdiction.

          (b) Pledgor shall pay to Agent upon demand the amount of any and all
costs and expenses, including the reasonable fees and expenses of its counsel
and of any experts and agents, that Agent may incur in connection with (i) the
administration of this Agreement, (ii) the custody or preservation of, or the
sale of, collection from, or other realization upon, any of the Pledged
Collateral, (iii) the exercise or enforcement of any of the rights of Agent
hereunder, or (iv) the failure by Pledgor to perform or observe any of the
provisions hereof.

          SECTION 13.  CONTINUING SECURITY INTEREST; TRANSFER OF LOANS. This
                       -----------------------------------------------      
Agreement shall create a continuing security interest in the Pledged Collateral
and shall (a) remain in full force and effect until the payment in full of all
Secured Obligations, (b) be binding upon Pledgor, its successors and assigns,
and (c) inure, 

                                     -12-
<PAGE>
 
together with the rights and remedies of Agent hereunder, to the benefit of
Agent and its successors, transferees and assigns. Without limiting the
generality of the foregoing clause (c), any Bank may, subject to the terms of
the Credit Agreement, assign or otherwise transfer its interest in the Credit
Agreement in whole or in part to any other Person, and such other Person shall
thereupon become vested with all benefits in respect thereof granted to Banks
herein or otherwise. Upon the payment in full of all Secured Obligations, the
security interest granted hereby shall terminate and all rights to the Pledged
Collateral shall revert to Pledgor. Upon any such termination Agent will, at
Pledgor's expense, execute and deliver to Pledgor such documents as Pledgor
shall reasonably request to evidence such termination and Pledgor shall be
entitled to the return, upon its request and at its expense, against receipt and
without recourse to Agent, of such of the Pledged Collateral as shall not have
been sold or otherwise applied pursuant to the terms hereof.

          SECTION 14.  AMENDMENTS; ETC.  Subject to Section 11.01 of the Credit
                       ---------------                                         
Agreement, no amendment, modification, termination or waiver of any provision of
this Agreement, and no consent to any departure by Pledgor therefrom, shall in
any event be effective unless the same shall be in writing and signed by Agent
and, in the case of any such amendment or modification, by Pledgor.  Any such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which it was given.

          SECTION 15.  NOTICES.  Any notice or other communication herein
                       -------                                           
required or permitted to be given shall be in writing and may be personally
served or sent by telefacsimile or United States mail or courier service and
shall be deemed to have been given when delivered in person or by courier
service, upon receipt of telefacsimile or five (5) Business Days after
depositing it in the United States mail with postage prepaid and properly
addressed.  For the purposes hereof, the address of each party hereto shall be
as set forth under such party's name on the signature pages hereof or, as to
either party, such other address as shall be designated by such party in a
written notice delivered to the other party hereto.

          SECTION 16.  FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                       -----------------------------------------------------  
No failure or delay on the part of Agent in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege.  All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

          SECTION 17.  SEVERABILITY.  In case any provision in or obligation
                       ------------                                         
under this Agreement shall be invalid, illegal or unenforceable in any
jurisdiction, the

                                     -13-
<PAGE>
 
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

          SECTION 18.  HEADINGS.  Section and subsection headings in this
                       --------                                          
Agreement are included herein for convenience of reference only and shall not
constitute a part of this Agreement for any other purpose or be given any
substantive effect.

          SECTION 19.  GOVERNING LAW; TERMS.  THIS AGREEMENT AND THE RIGHTS AND
                       --------------------                                    
OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF
CALIFORNIA, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO THE EXTENT
THAT THE CODE PROVIDES THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST
HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR PLEDGED
COLLATERAL ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF
CALIFORNIA. Unless otherwise defined herein or in the Credit Agreement, terms
used in Articles 8 and 9 of the UCC are used herein as therein defined.

          SECTION 20.  CONSENT TO JURISDICTION AND SERVICE OF PROCESS.  ALL
                       ----------------------------------------------      
JUDICIAL PROCEEDINGS BROUGHT AGAINST PLEDGOR ARISING OUT OF OR RELATING TO THIS
AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE
UNITED STATES FOR THE CENTRAL DISTRICT OF CALIFORNIA, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT PLEDGOR ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS
PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE
AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS AND IRREVOCABLY
AGREES TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS
AGREEMENT.  Pledgor hereby agrees that service of all process in any such
proceeding in any such court may be made by registered or certified mail, return
receipt requested, to Pledgor at its address provided in Section 15, such
service being hereby acknowledged by Pledgor to be sufficient for personal
jurisdiction in any action against Pledgor in any such court and to be otherwise
effective and binding service in every respect.  Nothing herein shall affect the
right to serve process in any other manner permitted by law or shall limit the
right of Agent to bring proceedings against Pledgor in the courts of any other
jurisdiction.

          SECTION 21.  WAIVER OF JURY TRIAL.  PLEDGOR AND AGENT HEREBY AGREE TO
                       --------------------                                    
WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF THIS AGREEMENT.  The scope of this waiver is
intended to be all-encompassing of any and all disputes that may be filed in any
court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach of duty claims, and all
other common law and statutory claims.  Pledgor and Agent each acknowledge that
this waiver is a material inducement for Pledgor and Agent to enter into a
business relationship, that Pledgor and Agent have already relied on this waiver
in entering into this Agreement and that each will continue to rely on this
waiver in their related future dealings.  Pledgor and Agent further warrant and
represent that each has reviewed this waiver with its legal counsel, and that
each knowingly and voluntarily waives its jury trial rights following
consultation with legal counsel.  THIS WAIVER IS IRREVOCABLE, MEANING THAT IT
MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING, AND THIS WAIVER SHALL APPLY TO
ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS
AGREEMENT.  In the event of litigation, this Agreement may be filed as a written
consent to a trial by the court.

          SECTION 22.  WAIVERS BY PLEDGOR.  Pledgor hereby waives, for the
                       ------------------                                 
benefit of Banks and Agent:

          (a) any right to require Agent or any Bank, as a condition of payment
or performance by Pledgor, to (i) proceed against Company, any other guarantor
of the Secured Obligations or any other Person, (ii) proceed against or exhaust
any security held from Company, any such other guarantor or any other Person,
(iii) proceed against or have resort to any balance of any deposit account or
credit on the books of Agent or any Bank in favor of Company or any other
Person, or (iv) pursue any other remedy in the power of Agent or any Bank
whatsoever;

          (b) any defense arising by reason of the incapacity, lack of authority
or any disability or other defense of Company including, without limitation, any
defense based on or arising out of the lack of validity or the unenforceability
of the Secured Obligations or any agreement or instrument relating thereto or by
reason of the cessation of the liability of Company from any cause other than
payment in full of the Secured Obligations;

          (c) any defense based upon any statute or rule of law which provides
that the obligation of a surety must be neither larger in amount nor in other

respects more burdensome than that of the principal;

                                     -15-
<PAGE>
 
          (d) any defense based upon Agent's or any Bank's errors or omissions
in the administration of the Secured Obligations, except behavior which amounts
to bad faith;

          (e) (i) any principles or provisions of law, statutory or otherwise,

the benefit of any statute of limitations affecting Pledgor's liability

          SECTION 23.  CERTAIN CALIFORNIA LAW WAIVERS.  As used in this Section
                       ------------------------------                          
23, any reference to "the principal" includes Company, and any reference to "the
creditor" includes Agent and each Bank.  In accordance with Section 2856 of the
California Civil Code:

          (a) Pledgor agrees (i) to waive any and all rights of subrogation and
reimbursement against Company or against any collateral or security granted by
Company for any of the Secured Obligations and (ii) to withhold the exercise of
any and all rights of subrogation, reimbursement and contribution against
Company, against any other guarantor of any of the Secured Obligations and
against any collateral or security granted by any such other guarantor for any
of the Secured Obligations until the Secured Obligations shall have been paid in
full and all letters of credit issued under the Credit Agreement and the other
Loan Documents shall have expired or been cancelled, all as more fully set forth
in Section 24;

          (b) Pledgor waives any and all other rights and defenses available to
such Pledgor by reason of Sections 2787 to 2855, inclusive, 2899 and 3433 of the
California Civil Code, including without limitation any and all rights or
defenses Pledgor may have by reason of protection afforded to the principal with
respect to any of the Secured Obligations, or to any other guarantor of any of
the Secured Obligations 

                                     -16-
<PAGE>
 
with respect to any of such guarantor's obligations under its guaranty, in
either case pursuant to the antideficiency or other laws of the State of
California limiting or discharging the principal's indebtedness or such
guarantor's obligations, including without limitation Section 580a, 580b, 580d,
or 726 of the California Code of Civil Procedure; and

          (c) Pledgor waives all rights and defenses arising out of an election
of remedies by the creditor, even though that election of remedies, such as a
nonjudicial foreclosure with respect to security for any Secured Obligation, has
destroyed Pledgor's rights of subrogation and reimbursement against the
principal by the operation of Section 580d of the Code of Civil Procedure or
otherwise; and even though that election of remedies by the creditor, such as
nonjudicial foreclosure with respect to security for an obligation of any other
guarantor (including any other Pledgor) of any of the Secured Obligations, has
destroyed Pledgor's rights of contribution against such other guarantor.

No other provision of this Pledge Agreement shall be construed as limiting the
generality of any of the covenants and waivers set forth in this Section 23.

          SECTION 24.  PLEDGOR'S RIGHTS OF SUBROGATION, CONTRIBUTION, ETC.
                       -------------------------------------------------- 
Pledgor hereby waives any claim, right or remedy, direct or indirect, that
Pledgor now has or may hereafter have against Company or any of its assets in
connection with this Pledge Agreement or the performance by Pledgor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute (including without limitation under
California Civil Code Section 2847, 2848 or 2849), under common law or otherwise
and including without limitation (a) any right of subrogation, reimbursement or
indemnification that Pledgor now has or may hereafter have against Company, (b)
any right to enforce, or to participate in, any claim, right or remedy that
Agent or any Bank now has or may hereafter have against Company, and (c) any
benefit of, and any right to participate in, any collateral or security now or
hereafter held by Agent or any Bank.  In addition, until the Secured Obligations
shall have been indefeasibly paid in full and all letters of credit issued under
the Credit Agreement shall have expired or been cancelled, Pledgor shall
withhold exercise of any right of contribution Pledgor may have against any
other guarantor of the Secured Obligations (including without limitation any
such right of contribution under California Civil Code Section 2848).  Pledgor
further agrees that, to the extent the waiver or agreement to withhold the
exercise of its rights of subrogation, reimbursement, indemnification and
contribution as set forth herein is found by a court of competent jurisdiction
to be void or voidable for any reason, any rights of subrogation, reimbursement
or indemnification Pledgor may have against Company or against any collateral or
security, and any rights of contribution Pledgor may have against any such other
guarantor, shall be junior and subordinate to any rights Agent or any Bank may
have against Company, to all right, title and interest Agent or any Bank  

                                     -17-
<PAGE>
 
may have in any such collateral or security, and to any right Agent or any Bank
may have against such other guarantor. If any amount shall be paid to Pledgor on
account of any such subrogation, reimbursement, indemnification or contribution
rights at any time when all Secured Obligations shall not have been paid in
full, such amount shall be held in trust for Agent on behalf of Banks and shall
forthwith be paid over to Agent for the benefit of Banks to be credited and
applied against the Secured Obligations, whether matured or unmatured, in
accordance with the terms hereof.

          SECTION 25.  FURTHER DOCUMENTATION.  Pledgor hereby agrees to promptly
                       ---------------------                                    
execute and deliver all further instruments and documents (including any
financing statements, continuations or amendments of such financing statements
and any consents necessary for the authorization of the transactions
contemplated hereby) and take all further action that may be necessary or
desirable, or that Agent may request, in order to perfect and protect any
security interest granted or purported to be granted hereby or to enable Agent
to exercise and enforce the rights and remedies of Agent hereunder with respect
to any Pledged Collateral or to carry out the provisions and purposes hereof.

          SECTION 26.  COUNTERPARTS.  This Agreement may be executed in one or
                       ------------                                           
more counterparts and by different parties hereto in separate counterparts, each
of which when so executed and delivered shall be deemed an original, but all
such counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.
