                                       9

<PAGE>   16
       the need to calculate the Consolidated Fixed Charge Coverage Ratio (such
       four full fiscal quarter period being referred to herein as the "Four
       Quarter Period") to the aggregate amount of Consolidated Fixed Charges

       EBITDA" and "Consolidated Fixed Charges" shall be calculated after

       incurrence of the Indebtedness giving rise to the need to make such
       calculation, as if such incurrence or repayment, as the case may be,
       occurred on the first day of the Reference Period, but excluding
       Indebtedness incurred or repaid under any revolving credit or similar
       facility pursuant to which amounts incurred may be repaid and reborrowed

       effected by such repayment and (b) any Asset Sales or Acquisitions
       (including, without limitation, any Acquisition giving rise to the need

       Acquired Indebtedness) occurring during the Reference Period, as if such
       Asset Sale or Acquisition occurred on the first day of the Reference
       Period.  Without limiting the generality of the foregoing, in making any
       calculation of the Consolidated Fixed Charge Coverage Ratio for any
       period commencing prior to January 26, 1994, the recapitalization which
       took effect on such date shall be deemed to have occurred on the first
       day of the Reference Period.  Furthermore, in calculating "Consolidated
       Interest Expense" and "Consolidated Fixed Charges" for purposes of
       determining the denominator (but not the numerator) of this
       "Consolidated Fixed Charge Coverage Ratio," (i) interest on outstanding
       Indebtedness determined on a fluctuating basis as of the Transaction
       Date and which will continue to be so determined thereafter shall be
       deemed to have accrued at a fixed rate per annum equal to the rate of
       interest on such Indebtedness in effect on the Transaction Date; (ii) if
       interest on any Indebtedness actually incurred on the Transaction Date
       may optionally be





                                       10

<PAGE>   17
       determined at an interest rate based upon a factor of a prime or similar
       rate, a eurocurrency interbank offered rate, or other rates, then the
       interest rate in effect on the Transaction Date will be deemed to have
       been in effect during the Reference Period; and (iii) notwithstanding
       clause (i) and (ii) above, interest on Indebtedness determined on a
       fluctuating basis, to the extent such interest is covered by agreements
       relating to Interest Rate Protection Obligations, shall be deemed to
       have accrued at the rate per annum resulting after giving effect to such
       agreements.  If such Person or any of its Subsidiaries directly or
       indirectly enters into a Guaranty Obligation with respect to
       Indebtedness of a third person (other than Indebtedness of a
       consolidated Subsidiary of such person or with respect to a consolidated
       Subsidiary of the Company other than Indebtedness of the Company), the

       Disqualified Capital Stock of such Person and its Subsidiaries on a
       consolidated basis; provided that if, during such period, such Person or
       any of its Subsidiaries shall have made any Asset Sales or Acquisitions,
       Consolidated Fixed Charges for such Person and its Subsidiaries for such
       period shall be adjusted to give pro forma effect to the Consolidated
       Fixed Charges directly attributable to the assets which are the subject
       of such Asset Sales or Acquisitions during such period.

               "Consolidated Interest Expense" means, with respect to any

       or as to which that Person is otherwise liable for reimbursement of
       drawings or payments; provided, that the amount in respect thereto to be
       included as a Contingent Obligation shall mean only that portion of such
       obligation or liability as is contingent, (ii) to purchase any
       materials, supplies or other Property from, or to obtain the services
       of, another Person if the relevant contract or other related document or
       obligation requires that payment for such materials, supplies or other
       Property, or for such services, shall be made regardless of whether
       delivery of such materials, supplies or other Property is ever made or
       tendered, or such services are ever performed or tendered, or (iii) in
       respect of any Interest Rate Protection Obligation that is not entered

       Obligation shall (subject, in the case of Guaranty Obligations, to the
       last sentence of the definition of "Guaranty Obligation") be deemed
       equal to the maximum reasonably anticipated liability in respect

                                (D)  the duration of the Interest Period
               applicable to the Loan included in such notice.  If the Notice
               of Borrowing shall fail to specify the duration of the Interest
               Period for any CD Rate Loan or Offshore Rate Loan, such Interest
               Period shall be 90 days or three months, respectively;

               (b)      After giving effect to any Loan, there shall not be
more than five different Interest Periods in effect.

                        (i)  elect to convert on any Business Day, any Base

       than $500,000, or that is in an integral multiple of $100,000 in excess
       thereof) into an Offshore Rate Loan or CD Rate Loan or;

                        (ii)  elect to convert on the last day of the
       applicable Interest Period any Offshore Rate Loan or CD Rate Loan having
       an Interest Period maturing on such day (or any part thereof in an
       amount not less than $100,000, or that is in an integral multiple of
       $100,000 in excess thereof) into a Base Rate Loan; provided that if
       there shall have been a partial assignment to an Assignee pursuant to
       Section 10.07, the minimum principal amount which may be converted into
       Base Rate Loans shall be $500,000 or any integral multiple of $100,000
       in excess thereof; and provided, further, that after giving effect to
       any partial conversion of an Offshore Rate Loan or CD Rate Loan into a
       Base Rate Loan, the principal balance of such Offshore Rate Loan or CD
       Rate Loan not so converted shall be not less than $500,000; or

                        (iii)  elect to renew on the last day of the applicable
       Interest Period any Offshore Rate Loan or CD Rate Loan having an
       Interest Period maturing on such day (or any part thereof in an amount
       not less than $500,000, or that is in an integral multiple of $100,000
       in excess thereof);

provided, that if the amount of any CD Rate Loan or Offshore Rate Loan shall
have been reduced by payment, prepayment, or conversion of part thereof to be
less than $500,000, such CD Rate Loan or Offshore Rate Loan shall automatically
convert into a Base Rate Loan, and on and after such date the right of the
Company to convert such Loan into, an Offshore Rate Loan or a CD Rate Loan, as
the case may be, shall terminate.

               (b)      The Company shall deliver in writing a Notice of
Conversion/Continuation to be received by the Bank not later than 9:00 a.m.
(San Francisco time) at least (i) three Business Days in advance of the

                                       32

<PAGE>   39
                                (A)      the proposed Conversion Date or
               continuation date;

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

                                (C)      the nature of the proposed conversion
               or continuation; and

                                (D)      the duration of the requested Interest
               Period.

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

               (d)      Unless the Bank shall otherwise agree, during the
existence of a Default or Event of Default, the Company may not elect to have a
Loan converted into or continued beyond the end of the applicable Interest
Period as an Offshore Rate Loan or a CD Rate Loan.

               (e)      Notwithstanding any other provision contained in this
Agreement, after giving effect to any conversion or continuation of any Loans,
there shall not be more than five different Interest Periods in effect.

       2.05  Voluntary Termination or Reduction of Commitment.  The Company
may, upon not less than five Business Days' prior written notice to the Bank,
terminate the Commitment or permanently reduce the Commitment by an aggregate
minimum amount of $1,000,000 or any multiple of $100,000 in excess thereof (or
of the balance of the Commitment, if less); provided that no such reduction or
termination shall be permitted if, after giving effect thereto and to any
prepayments of the Loans made on the effective date thereof, the (i)
then-Effective Amount of the Loans plus L/C Obligations would exceed the amount
of the Commitment then in effect; or (ii) then-Effective Amount in respect of
L/C Obligations would exceed the L/C Commitment; provided, further, that once
reduced in accordance with this Section 2.05, the Commitment may not be
increased.  All accrued commitment fees to, but not including the effective
date of any reduction or termination of Commitment with respect to the portion
thereof being so reduced or terminated, shall be paid on





                                       33

<PAGE>   40
the effective date of such reduction or termination.  Any notice of commitment
reduction or termination shall specify to what extent (if any) to which any
such reduction shall be applied to reduce as well the L/C Commitment. Any
termination of all of the Commitment shall terminate as well the L/C
Commitment.

       2.06  Optional Prepayments. Subject to Section 4.04, the Company may, at
any time or from time to time, upon at least three Business Days' written
notice to the Bank in the case of Offshore Rate Loans or CD Rate Loans, or
notice given no later than 10:00 a.m. on the date of prepayment in the case of
Base Rate Loans, prepay Loans in whole or in part, in amounts of $500,000 or
any multiple of $100,000 in excess thereof in the case of Offshore Rate Loans
or CD Rate Loans, or in amounts of $100,000 or any multiple in excess of
$100,000 thereof in the case of Base Rate Loans.  Such notice of prepayment
shall specify the date and amount of such prepayment and whether such
prepayment is of Base Rate Loans, CD Rate Loans or Offshore Rate Loans, or any
combination thereof.  Such notice shall not thereafter be revocable by the
Company.  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 Prepayments; Mandatory Reductions.

               (a)      Change of Control.  No later than 45 days after the
Bank has received notice of a Change of Control pursuant to subsection 7.03(i)
(or upon and at any time after the occurrence of any Change of Control if the
Company is in default of its obligations to deliver such a notice), the Bank
may by notice to such effect to the Company (i) declare the Commitment
(including the L/C Commitment) to be terminated, whereupon the Commitment shall
forthwith be terminated, and (ii) declare an amount equal to the maximum
aggregate amount that is or at any time thereafter may become available for
drawing under any outstanding Letters of Credit (whether or not any beneficiary
shall have presented, or shall be entitled at such time to present, the drafts
or other documents required to draw under such Letters of Credit) to be
immediately due and payable, or demand that the Company Cash Collateralize the
L/C Obligations to the extent of outstanding and wholly or partially undrawn
Letters of Credit, whereupon the Company shall so Cash Collateralize the L/C
Obligations; and declare the unpaid principal amount of all outstanding Loans,
all interest accrued and unpaid thereon, and all other amounts owing or payable
hereunder or under any other Loan Document to be immediately due





                                       34

<PAGE>   41
and payable; without presentment, demand or protest, all of which are hereby
expressly waived by the Company.

               (b)      General.  Any prepayments pursuant to this Section 2.07
shall be applied first to any Base Rate Loans then outstanding and then to CD
Rate Loans and Offshore Rate Loans with the shortest Interest Periods
remaining.  All prepayments of Loans pursuant to this Section 2.07 shall be
made together with accrued interest to the date of such payment on the
principal amount repaid, together with any amounts payable under Section 4.04;
provided, that if any such prepayment would cause the Company to incur
Obligations pursuant to Section 4.04 with respect to CD Rate Loans or Offshore
Rate Loans, the Company may Cash Collateralize such CD Rate Loans or Offshore
Rate Loans until the last day of the Interest Period related thereto, at which
time such Cash Collateral shall be applied by the Bank to pay such Loans.

       2.08  Repayment.  The Company shall repay to the Bank in full on the
Revolving Termination Date the aggregate principal amount of the Loans
outstanding on such date.

       2.09  Interest.

               (a)      Subject to subsection 2.09(c), each Loan shall bear
interest on the outstanding principal amount thereof from the date when made at
a rate per annum equal to the Offshore Rate, the Base Rate or the CD Rate, as
the case may be, plus the Applicable Rate.

               (b)      Interest on each Loan shall be payable in arrears on
each Interest Payment Date.  Interest shall also be payable on the date of any
prepayment of Loans pursuant to 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 payable on
demand.

               (c)      While any Event of Default exists or after
acceleration, 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
Obligations due and unpaid, at a rate per annum which is determined by adding
2% per annum to the Applicable Rate then in effect for such Loans and, in the
case of Obligations not subject to an Applicable Rate, at a rate per annum
equal to the Base Rate plus 2%; provided, however, that, on and after the
expiration of any Interest Period applicable to any Offshore Rate Loan or CD
Rate Loan outstanding on the date of occurrence of such Event of Default or
acceleration, the principal amount of such Loan shall, during the continuation
of





                                       35

<PAGE>   42
such Event of Default or after acceleration, bear interest at a rate per annum
equal to the Base Rate plus 2%.

       2.10  Commitment Fee.  The Company shall pay to the Bank a commitment
fee equal to the Applicable Rate per annum times the average daily unused
amount of the Commitment.  Such fee shall accrue from the Closing Date to the
later of (i) the Revolving Termination Date or (ii) the date that all Loans and
L/C Obligations outstanding on the Revolving Termination Date are paid in full,
and shall be due and payable quarterly in arrears on the last Business Day of
each calendar quarter commencing on the last day of the calendar quarter within
which the Closing Date occurs through the later of the dates referred to in
clauses (i) and (ii) above, with the final payment to be made on the later of
such dates.

       2.11  Computation of Fees and Interest.

               (a)      All computations of interest payable in respect of Base
Rate Loans at all times as the Base Rate is determined by the Bank'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 under
this Agreement 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 period
during which interest or such fees are computed from the first day thereof to
the last day thereof.

               (b)      Any change in the interest rate on a Loan resulting
from a change in the Applicable Rate, Reserve Percentage, Eurocurrency Reserve
Percentage, or the Assessment Rate shall become effective as of the opening of
business on the day on which such change in the Applicable Rate, Reserve
Percentage, Eurocurrency Reserve Percentage, or the Assessment Rate becomes
effective.

               (c)      Each determination of an interest rate by the Bank
pursuant to any provision of this Agreement shall be conclusive and binding on
the Company in the absence of manifest error.

       2.12  Payments by the Company.

               (a)      All payments (including prepayments) to be made by the
Company on account of principal, interest, fees and other amounts required
hereunder shall be made without set-off or counterclaim; shall, except as
otherwise expressly provided herein, be made to the Bank at the Bank's Payment
Office, and shall be made in dollars and in immediately available funds, no





                                       36

<PAGE>   43
later than 11:00 a.m. (San Francisco time) on the date specified herein.  Any
payment which is received by the Bank later than 11:00 a.m. (San Francisco
time) shall be deemed to have been received on the immediately succeeding
Business Day and any applicable interest or fee shall continue to accrue.

               (b)      Whenever any payment hereunder shall be stated to be
due on a day other than a Business Day, such payment shall instead be due and
made on the next succeeding 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; subject to the provisions set forth in the definition of "Interest Period"
herein.


                                  ARTICLE III

                             THE LETTERS OF CREDIT

       3.01  The Letter of Credit Subfacility.

               (a)      On the terms and conditions set forth herein, the Bank
agrees (i) 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 (or for the account of any Subsidiary of the
Company, provided, that the applicable L/C Application shall be submitted
jointly and severally by the Company and its Subsidiary and the Company shall
be liable for all L/C Obligations with respect to such Letter of Credit, which
shall be deemed for all purposes hereof to be a Letter of Credit issued for the
account of such Company), and to amend or renew Letters of Credit previously
issued by it, in accordance with subsection 3.02(b), and (ii) to honor drafts
under the Letters of Credit; provided, that the Bank shall not be obligated to
Issue any Letter of Credit if as of the date of Issuance of such Letter of
Credit (A) the Effective Amount of all L/C Obligations plus the Effective
Amount of all Loans shall exceed the Commitment, or (B) the Effective Amount of
all L/C Obligations shall 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 Bank shall be under no obligation to Issue any
Letter of Credit if:





                                       37

<PAGE>   44
                        (i)  any order, judgment or decree of any Governmental
       Authority or arbitrator shall by its terms purport to enjoin or restrain
       the Bank from Issuing such Letter of Credit, or any Requirement of Law
       applicable to the Bank or any request or directive (whether or not
       having the force of law) from any Governmental Authority with
       jurisdiction over the Bank shall prohibit, or request that the Bank
       refrain from, the Issuance of letters of credit generally or such Letter
       of Credit in particular or shall impose upon the Bank with respect to
       such Letter of Credit any restriction, reserve or capital requirement
       (for which the Bank is not otherwise compensated hereunder) not in
       eff
