               "Consolidated Fixed Charge Coverage Ratio" means, with respect to
the Company for any period, the ratio of (a) the aggregate amount of Adjusted
EBITDA plus Capital Expenditures incurred in such period for the four full
fiscal quarters for which financial information in respect thereof is available
immediately preceding the date of the transaction (the "Transaction Date")
giving rise to 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 (b) the aggregate amount of Consolidated Fixed Charges
for the Four Quarter Period. In addition to and without limitation of the
foregoing, for purposes of this definition, "Adjusted EBITDA" and "Consolidated
Fixed Charges" shall be calculated after giving effect on a pro forma basis for
the period of such calculation to, without duplication, (i) any incurrences, and
permanent repayments out of the proceeds of such incurrences, of Indebtedness of
the Company or any of its Subsidiaries occurring during the period commencing on
the first day of the Four Quarter Period through the Transaction Date (the
"Reference Period"), including the 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 for working
capital purposes (it being understood that such incurrences and repayments
referred to in this exclusion are included in the calculation of "Consolidated
Fixed Charge Coverage Ratio" on an actual basis), unless a permanent reduction
in the commitments is effected by such repayment and (ii) any Asset Sales or
Acquisitions (including any Acquisition giving rise to the need to make such
calculation as a result of the Company or one of its Subsidiaries (including any
Person who becomes a Subsidiary as a result of the Acquisition) incurring,
assuming or otherwise being liable for Acquired Indebtedness) occurring during
the Reference Period, as if such Asset Sale or Acquisition

                                       5
<PAGE>   11

occurred on the first day of the Reference Period. Without limiting the
generality of the foregoing, in calculating "Consolidated Interest Expense" and
"Consolidated Fixed Charges" for purposes of determining the denominator (but
not the numerator) of "Consolidated Fixed Charge Coverage Ratio," (A) 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; (B) if interest on any
Indebtedness actually incurred on the Transaction Date may optionally be
determined at an interest rate based upon a factor of a prime or similar rate, a
eurocurrency inter-bank 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 (C) notwithstanding the immediately preceding clauses (A)
and (B), interest on Indebtedness determined on a fluctuating basis, to the
extent such interest is covered by Swap Agreements, shall be deemed to have
accrued at the rate per annum resulting after giving effect to such agreements.

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),

such period, the Company or any of its consolidated Subsidiaries shall have made
any Asset Sales or Acquisitions, "Consolidated Fixed Charges" for the Company
and its consolidated Subsidiaries for such period shall be adjusted to give pro
forma effect to the Consolidated Fixed Charges directly attributable to the

period.

               "Consolidated Interest Expense" means, with respect to the

payment obligation, (iv) all commissions, discounts and other fees and charges
owed with respect to letters of credit and bankers' acceptance financing and (v)

Obligations paid, accrued or scheduled to be paid or accrued by the Company and

of the primary obligor to make payment of such primary obligation, or (iv)

ever made or tendered, or such services are ever performed or tendered, or (d)
in respect of any Swap Contract. The amount of any Contingent Obligation shall,
in the case of Guaranty Obligations, be deemed equal to the stated or

Obligation is made or, if not stated or if indeterminable, the maximum
reasonably anticipated liability in respect thereof, and in the case of other

        part thereof in an amount not less than $100,000, or that is in an
        integral multiple of $100,000 in excess thereof) into Prime Rate Loans;
        provided that, if there shall have been a partial assignment to an
        Assignee pursuant to Section 10.08, the minimum principal amount which
        may be converted into Prime Rate Loans shall be $500,000 or any integral
        multiple of $100,000 in excess thereof; or

                      (iii) elect to continue, as of the last day of the
        applicable Interest Period, any LIBOR Loans having Interest Periods
        expiring 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 at any time the aggregate amount of LIBOR Loans in respect of
any Borrowing is reduced, by payment, prepayment, or conversion of part thereof
(but not by partial assignment to an Assignee pursuant to Section 10.08), to be
less than $500,000, such LIBOR Loans shall automatically convert into Prime Rate
Loans, and on and after such date the right of the Company to continue such
Loans as, and convert such Loans into, LIBOR Loans shall terminate.

               (b) The Company shall deliver a Notice of Conversion/Continuation
for receipt by the Bank not later than 9:00 a.m. (San Francisco time) at least
(i) three Business Days in advance of the Conversion/Continuation Date, if the
Loans are to be converted into or continued as LIBOR Loans; and (ii) on the
Conversion/Continuation Date, if the Loans are to be converted into Prime 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
               conversion or continuation; and

                                       21
<PAGE>   27

                             (D) other than in the case of conversions into
               Prime Rate Loans, the duration of the requested Interest Period.

               (c) If, upon the expiration of any Interest Period applicable to
LIBOR Loans, the Company has failed to select timely a new Interest Period to be
applicable to such LIBOR Loans, as the case may be, or if any Default or Event
of Default then exists, then the Company shall be deemed to have elected to
convert such LIBOR Loans into Prime Rate Loans effective as of the expiration
date of such Interest Period, and all conditions to such conversion shall be
deemed to have been satisfied.

               (d) Unless the Bank 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 a LIBOR Loan.

               (e) Unless the Bank otherwise consents, after giving effect to
any conversion or continuation of Loans, there may not be more than five (5)
different Interest Periods in effect.

        2.05   Voluntary Termination or Reduction of the Commitment.

        The Company may, upon five Business Days prior 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); unless, after giving effect thereto
and to any prepayments of the Loans made on the effective date thereof, the then
Effective Amount of the Loans and the L/C Obligations would exceed the
Commitment then in effect. Once reduced in accordance with this Section 2.05,
the Commitment (and, to the extent reduced in accordance with the provisions
hereof, the L/C Commitment) may not be increased. All accrued commitment fees to
the effective date of any reduction or termination of the Commitment shall be
paid on the effective date of such reduction or termination. Any notice of a
reduction of the Commitment shall specify to what extent if any to which to such
reduction shall be applied to reduce the L/C Commitment. Any termination of the
entire Commitment shall also terminate the entire L/C Commitment.

        2.06   Optional Prepayments.

        Subject to Section 4.04, the Company may, at any time or from time to
time, upon irrevocable notice received by the Bank, in the case of LIBOR Loans,
not less than three Business Days prior to the requested prepayment date, and,
in the case of Prime Rate Loans, on the Business Day prior to the requested
prepayment date, prepay the Loans, in whole or in part, in minimum amounts of
(a) $100,000 or any multiple of $100,000 in excess thereof in the case of Prime
Rate Loans and (b) $500,000 or any multiple of $100,000 in excess thereof in the
case of LIBOR Loans. Such notice of prepayment shall specify the date and amount
of such prepayment and the Type(s) of Loans to be prepaid. If any such notice is
given by the Company, then 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   Cash Collateralization; Mandatory Prepayments.

               (a) Subject to Section 4.04, if, on any date, the Effective
Amount of all Loans and L/C Obligations together exceeds the Commitment, then
the Company shall immediately, and without notice or demand, prepay the
outstanding principal amount of the Loans or repay all unreimbursed drawings
under all Letters of Credit (including L/C Borrowings) in an amount equal to
such excess.

                                       22
<PAGE>   28

               (b) No later than forty-five days after the Bank has received
notice of a Change of Control pursuant to Section 7.03 (or upon and at any time
after the occurrence of any Change of Control if the Company is in default of
its obligation to deliver such a notice), the Bank may by notice to such effect
to the Company: (i) declare the Commitment to be terminated, whereupon the
Commitment shall automatically terminate; 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 and payable without presentment, demand or protest, all of which
are hereby expressly waived by the Company.

               (c) Any prepayments pursuant to this Section 2.07 shall be
applied first to any Prime Rate Loans then outstanding and then to outstanding
LIBOR Loans with the shortest Interest Periods then remaining. All payments of
Loans and L/C Borrowings pursuant to this Section 2.07 shall be made together
with interest accrued 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 LIBOR Loans, the Company may Cash Collateralize
such LIBOR Loans until the last day of the Interest Period related thereto, at
which time such Cash Collateral shall be applied by the Bank to repay such
Loans.

        2.08   Repayment.

        The Company shall repay the Bank on the Revolving Termination Date the
aggregate principal amount of all Loans outstanding on such date.

        2.09   Interest.

               (a) Subject to the Company's right to convert to other Types of
Loans under Section 2.04): (i) each Prime Rate Loan shall bear interest on the
outstanding principal amount thereof from the applicable Borrowing Date at a
rate per annum equal to the Prime Rate minus one percent (1.00%) per annum; and
(ii) each LIBOR Loan shall bear interest on the outstanding principal amount
thereof from the applicable Borrowing Date at a rate per annum equal to LIBOR
plus five-eighths of one percent (0.625%) per annum.

               (b) Interest on each 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 Bank.

               (c) Notwithstanding subsection (a) of this Section, 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 outstanding Obligations, at a rate per annum
which is determined by adding two percent (2.00%) per annum to the rate
otherwise then in effect for such Loans and, in the case of Obligations not
Loans, at a rate per annum equal to the Prime Rate plus

                                       23
<PAGE>   29

one percent (1.00%) per annum; provided that, on and after the expiration of any
Interest Period applicable to any LIBOR 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 such Event of Default or after
acceleration, bear interest at a rate per annum equal to the Prime Rate plus one
percent (1.00%) per annum. All such interest shall be payable upon demand.

               (d) Notwithstanding anything to the contrary contained herein,
the obligations of the Company to the 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 the Bank would be contrary to
the provisions of any law applicable to the Bank limiting the highest rate of
interest that may be lawfully contracted for, charged or received by the Bank,
and, in such event, the Company shall pay the Bank interest at the highest rate
permitted by applicable law.

        2.10   Commitment Fee.

        The Company shall pay to the Bank a commitment fee on the average daily
unused portion of the Commitment, computed on a monthly basis in arrears on the
last Business Day of each calendar month based upon the daily utilization for
that month as calculated by the Bank, equal to such unused portion as so
calculated multiplied by the Applicable Commitment Fee Percentage for such
period. Such commitment fee shall accrue from the Closing Date to the Revolving
Termination Date and shall be due and payable monthly in arrears on the last
Business Day of each month commencing on December 31, 1999 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 the
Commitment hereunder, 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 monthly payment being calculated on the basis of
the period from such reduction or termination date to such monthly payment date.
The commitment fees provided in this Section shall accrue at all times after the
Closing Date, including at any time during which one or more conditions in
Article 5 are not met, and are non-refundable.

        2.11   Computation of Fees and Interest.

               (a) All computations of interest for Prime Rate Loans 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 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 by the Bank shall be
conclusive and binding on the Company in the absence of manifest error.

        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 Bank at the Bank'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. Any
payment

                                       24
<PAGE>   30

received by the Bank 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" contained 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.

                                    ARTICLE 3

                              THE LETTERS OF CREDIT

        3.01   The Letter of Credit Subfacility.

               (a) On the terms and conditions set forth herein and from time to
time on any Business Day during the period from the Closing Date to the
Revolving Termination Date, the Bank agrees (i) 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) in an aggregate
amount not to exceed the L/C Commitment, 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 and after giving effect to the Issuance
of such Letter of Credit (the "Issuance Date"), (A) the Effective Amount of all
L/C Obligations exceeds (or would exceed) the L/C Commitment or (B) the
Effective Amount of all L/C Obligations and Loans together exceeds (or would
exceed) the 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 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 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
        effect on the Closing Date, or shall impose upon the Bank any
        unreimbursed loss, cost or expense which was not applicable on the
        Closing Date and which the Bank in good faith deems material to it;

                      (ii) the Bank has received written notice from 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 5 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, or (B) more than 200
        days after the Revolving Termination Date, unless the Bank has approved
        such expiry date in writing;

                                       25
<PAGE>   31

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

                      (v) any standby Letter of Credit is for the purpose of
        supporting the issuance of any letter of credit by any other Person or
        for the purpose of supporting any debt for borrowed money.

        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 Bank at least three Business Days
(or such shorter time as the Bank may agree in a particular instance) prior to
the proposed date of issuance. Each such request for issuance of a Letter of
Credit shall be in the form of an L/C Application and shall specify in form and
detail satisfactory to the 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 Bank may reasonably require.

               (b) Unless the issuance, amendment or renewal of any Letter of
Credit is not then permitted under Section 3.01(a)(ii) as a result of the
limitations set forth in clauses (A) or (B) thereof or under Section 3.01(b), or
one or more conditions specified in Article 5 are not then satisfied, then,
subject to the terms and conditions hereof, the Bank shall, on the requested
Issue date, Issue a Letter of Credit for the account of the Company in
accordance with the Bank's usual and customary business practices.

               (c) From time to time while a Letter of Credit is outstanding and
prior to the Revolving Termination Date, the Bank will, upon the written request
of the Company received by the Bank at least four Business Days (or such shorter
time as the Bank may agree in a particular instance) 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 in the form of an L/C Amendment
Application and shall specify in form and detail satisfactory to the 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 Bank may reasonably
require. The Bank shall be under no obligation to amend any Letter of Credit if:
(A) the 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.

               (d) From time to time while a Letter of Credit is outstanding and
prior to the Revolving Termination Date, the Bank shall, upon the written
request of the Company received by the Bank at least four Business Days (or such
shorter time as the Bank may agree in a particular instance) prior to the
proposed date of notification of renewal, be entitled to authorize the automatic
renewal of any Letter of Credit issued by it. Each such request for renewal of a
Letter of Credit shall be made in the form of an L/C Amendment Application and
shall specify in form and detail satisfactory to the 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 Bank may require.
The Bank shall be under no obligation to renew any Letter of Credit if: (A) the

                                       26
<PAGE>   32

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 provides that it shall
be automatically renewed unless the beneficiary thereof receives notice from the
Bank that such Letter of Credit will not be renewed, and if at the time of
renewal the 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 Bank shall not have received an L/C Amendment Application from
the Company with respect to such renewal or any other written direction by the
Company with respect thereto, the Bank shall nonetheless be permitted to allow
such Letter of Credit to renew, and the Company hereby authorizes such renewal,
and, accordingly, the Bank shall be deemed to have received an L/C Amendment
Application from the Company requesting such renewal.

               (e) The Bank may, at its election, 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 200 days after 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).

        3.03   Drawings and Reimbursements.

               (a) In the event of any request for a drawing under a Letter of
Credit by the beneficiary or transferee thereof, the Bank will promptly notify
the Company. The Company shall reimburse the Bank prior to 10:00 a.m. (San
Francisco time), on each date that any amount is paid by the Bank under any
Letter of Credit (each such date, an "Honor Date"), in an amount equal to the
amount so paid by the Bank. In the event the Company fails to reimburse the Bank
for the full amount of any drawing under any Letter of Credit by 10:00 a.m. (San
Francisco time) on the Honor Date, the Company will be deemed to have requested
that Prime Rate Loans be made by the Bank to be disbursed on the Honor Date in
respect of such Letter of Credit, subject to the amount of the unutilized
portion of the Commitment and subject to the conditions set forth in Section
5.02. Solely for the purposes of making such Prime Rate Loans, the minimum
amount limitations set forth in Section 2.03 shall not be applicable. Any notice
given by the Bank pursuant to this Section 3.03(c) 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.

               (b) With respect to any unreimbursed drawing that is not
converted into Loans consisting of Prime 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 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 equal to the Prime Rate plus one and one-half
percent (1.50%) per annum.

        3.04   Role of the Bank.

        The Bank and the Company agree that, in paying any drawing under a
Letter of Credit, the Bank shall not have any responsibility to obtain any
document (other than any sight draft and certificates 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. The Company

                                       27
<PAGE>   33

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 that this
assumption is not intended to, and shall not, preclude the Company from pursuing
such rights and remedies as it may have against the beneficiary or transferee at
law or under any other agreement. No Indemnified Person nor any Indemnified
Person's correspondents, participants or assignees, shall be liable or
responsible for any of the matters described in subsections (a) through (h) of
Section 3.05; provided that the Company may have a claim against the Bank, and
the 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 Bank's willful misconduct or
gross negligence or the 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: (a) the 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 (b) the 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.

        3.05   Obligations Absolute.

        The obligations of the Company under this Agreement and any L/C-Related
Document to reimburse the Bank for a drawing under a Letter of Credit, and to
repay any L/C Borrowing and any drawing under a Letter of Credit converted into
Loans, shall be unconditional and irrevocable, and shall be paid strictly in
accordance with the terms of this Agreement and each such other L/C-Related
Document under all circumstances, including the following:

               (a) any lack of validity or enforceability of this Agreement, any
L/C-Related Document or other Credit Document;

               (b) any change in the time, manner or place of payment of, or in
any other term of, all or any of the obligations of the Company in respect of
any Letter of Credit or any other amendment or waiver of or any consent to
departure from all or any of the L/C-Related Documents;

               (c) the existence of any claim, set-off, defense or other right
that the Company may have at any time against any beneficiary or any transferee
of any Letter of Credit (or any Person for whom any such beneficiary or any such
transferee may be acting), the 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;

               (d) any draft, demand, certificate or other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; or any loss or delay in the transmission or otherwise of any
document required in order to make a drawing under any Letter of Credit;

               (e) any payment by the Bank under any Letter of Credit against
presentation of a draft or certificate that does not strictly comply with the
terms of any Letter of Credit; or any payment made by the Bank under any Letter
of Credit to any Person purporting to be a trustee in bankruptcy,
debtor-in-possession, assignee for the benefit of creditors, liquidator,

        Upon (a) the request of the Bank (i) if the Bank has honored any full or
partial drawing request on any Letter of Credit and such drawing has resulted in
an L/C Borrowing hereunder and (ii) if, as of the Revolving Termination Date,
any Letters of Credit may for any reason remain outstanding and partially or
wholly undrawn, or (b) the occurrence of the circumstances described in Section
2.07 requiring the Company to Cash Collateralize Letters of Credit, then, the
Company shall immediately Cash Collateralize or cause to be Cash Collateralized
the L/C Obligations in an amount equal to such L/C Obligations. Such amount,
when received by the Bank, shall be held by the Bank and maintained in a blocked
deposit account or deposit accounts at the Bank, as Cash Collateral for

interest in all such cash, deposit accounts and deposit account balances.

                                    ARTICLE 4

                     TAXES, YIELD PROTECTION AND ILLEGALITY

        4.01   Taxes.

               (a) Any and all payments by the Company to the Bank under this
Agreement and any other Credit 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 the Bank, 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), the Bank 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 the Bank, at the time
        interest is paid, Further Taxes in the amount that the Bank specifies is
        necessary to preserve the after-tax yield that 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 the Bank
for the full amount of (i) Taxes, (ii) Other Taxes, and (iii) Further Taxes in
the amount that the Bank specifies is necessary to preserve the after-tax yield
that 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 30
days after the date the Bank makes written demand therefor.

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

               (e) If the Company is required to pay any amount to the Bank
pursuant to subsection (b) or (c) of this Section, then the 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
and absolute judgment of the Bank is not otherwise disadvantageous to the Bank.

                                       30
<PAGE>   36

        4.02   Illegality.

               (a) If the Bank determines that the introduction of any
Requirement of Law, or any change in any Requirement of Law, or in the
interpretation 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 the Bank or its Applicable Lending Office to make LIBOR
Loans, then, on notice thereof by the Bank to the Company, any obligation of the
Bank to make LIBOR Loans shall be suspended until the Bank notifies the Company
that the circumstances giving rise to such determination no longer exist.

               (b) If the Bank determines that it is unlawful to maintain any
LIBOR Loan, the Company shall, upon its receipt of notice of such fact and
demand from the Bank, prepay in full all LIBOR Loans 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 LIBOR Loans to such day, or immediately, if the Bank may not
lawfully continue to maintain such LIBOR Loans. If the Company is required to so
prepay any LIBOR Loan, then, concurrently with such prepayment, the Company
shall borrow from the Bank, in the amount of such repayment, a Prime Rate Loan.

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

        4.03   Increased Costs and Reduction of Return.

               (a) If the Bank shall determine that, due to either (i) the
introduction of or any change (other than any change by way of imposition of or
increase in reserve requirements included in the calculation of the LIBOR) in or
in the interpretation of any law or regulation after the Closing Date or (ii)
the compliance with any guideline or request from any central bank or other
Governmental Authority after the Closing Date (whether or not having the force
of law), there shall be any increase in the cost to the Bank of agreeing to make
or making, funding or maintaining any LIBOR Loans, then the Company shall be
liable for, and shall from time to time, not later than thirty days following
demand therefor by the Bank, pay to the Bank such additional amounts as are
sufficient to compensate the Bank for such increased costs.

               (b) If the Bank shall have reasonably 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 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 the Bank's or
such corporation's policies with respect to capital adequacy and the Bank's
desired return on capital) determines that the amount of such capital is
increased as a consequence of the Commitment, loans, credits or obligations
under this Agreement, then, upon demand of the Bank to the Company, the Company
shall immediately pay to the Bank, not later than thirty days following demand
therefor, additional amounts sufficient to compensate the Bank for such
increase.

        4.04   Funding Losses.

        The Company shall reimburse the Bank and hold the Bank harmless from any
actual 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 LIBOR Loan (including after any acceleration
thereof);

               (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 any LIBOR Loan on a day that
is not the last day of the relevant Interest Period; or

               (e) the conversion of any LIBOR Loan to a Prime 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 LIBOR Loans hereunder 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 Bank under this
Section and under Section 4.03(a), each LIBOR Loan made by the Bank (and each
related reserve, special deposit or similar requirement) shall be conclusively
deemed to have been funded at the Base LIBOR used in determining the LIBOR for
such LIBOR Loan by a matching deposit or other borrowing in the inter-bank
eurodollar market for a comparable amount and for a comparable period, whether
or not such LIBOR Loan is in fact so funded.

        4.05   Inability to Determine Rates.

        If the Bank determines that for any reason adequate and reasonable means
do not exist for determining the LIBOR for any requested Interest Period with
respect to a proposed LIBOR Loan, or that the LIBOR applicable pursuant to
Section 2.09(a) for any requested Interest Period with respect to a proposed
LIBOR Loan does not adequately and fairly reflect the cost to the Bank of
funding such Loan, then the Bank will promptly so notify the Company.
Thereafter, the obligation of the Bank to make or maintain LIBOR Loans hereunder
shall be suspended until the Bank revokes such notice in writing. Upon receipt
of such notice, the Company may revoke without further obligation or penalty any
Notice of Borrowing or Notice of Conversion/Continuation then submitted by it.
If the Company does not revoke such Notice, the Bank 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 Prime Rate Loans instead of LIBOR Loans.

        4.06   Reserves on LIBOR Loans.

        The Company shall pay to the Bank, as long as the 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

                                       32
<PAGE>   38

amount of each LIBOR 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 prima facie evidence of such amounts), payable on each
date on which interest is payable on such Loan, provided that the Company shall
have received at least fifteen days prior written notice of such additional
costs from the Bank. If the Bank fails to give notice fifteen days prior to the
relevant Interest Payment Date, such additional interest shall be payable
fifteen days from receipt of such notice.

        4.07   Certificates of the Bank.

        If the Bank claims reimbursement or compensation under this Article 4,
it shall deliver to the Company a certificate setting forth in reasonable detail
the amount payable to the Bank hereunder and such certificate shall be prima
facie evidence of the amounts stated therein.

        4.08   Survival.

        The agreements and obligations of the Company in this Article 4 shall
survive the payment of all other Obligations.

                                    ARTICLE 5

        The proceeds of the Loans are to be used solely for the purposes set
forth in and permitted by Section 7.11 and Section 8.07. Neither the Company nor

Company and its Subsidiaries are subject to no Liens other than Permitted Liens.

        The Company and each of its Subsidiaries have filed all federal and

        and its Subsidiaries as of the date thereof and results of operations

        show all material indebtedness and other liabilities, direct or
        contingent, of the Company and its consolidated Subsidiaries as of the

               (b) Since September 30, 1999 (assuming that this Agreement were
in effect on such date and thereafter), there has been no Material Adverse

        6.11   Environmental Matters.

        The Company conducts in the Ordinary Course of Business a review of the
effect of existing Environmental Laws and existing Environmental Claims on its
business, operations and properties and the business, operations and properties
of its Subsidiaries, and, as a result thereof, the Company has reasonably
concluded that, except as specifically disclosed in Schedule 6.11, such
Environmental Laws and Environmental Claims could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. In that
regard, the on-going operations of the Company and each of its Subsidiaries
comply in all respects with all Environmental Laws, except to the extent that
the failure to so comply could not reasonably be expected to have a Material
Adverse Effect.

        6.12   Regulated Entities.

        None of the Company, any Person controlling the Company, or any
Subsidiary of the Company is an "Investment Company" within the meaning of the
Investment Company Act of 1940. The Company is not subject to regulation under
the Public Utility Holding Company Act of 1935, the Federal Power Act, the
Interstate Commerce Act, any state public utilities code, or any other federal
or state statute or regulation limiting its ability to incur Indebtedness.

        6.13   No Burdensome Restrictions; Labor Relations.

               (a) Neither the Company nor any of its Subsidiaries is a party to
or bound by any Contractual Obligation, or subject to any restriction in any

expected to have a Material Adverse Effect.

               (b) There are no strikes, lockouts or other labor disputes
against the Company or any of its Subsidiaries or, to the best knowledge of the
Company, threatened against or affecting the Company or any of its Subsidiaries,
and no significant unfair labor practice complaint is pending against the
Company or any of its Subsidiaries or, to the best knowledge of the Company,
threatened against any of

                                       38
<PAGE>   44

them before any Governmental Authority which, in the case of any of the
foregoing, could reasonably be expected to have a Material Adverse Effect.

        6.14   Solvency.

        The Company is Solvent and as of the Closing Date: (a) the Company does
not intend to, and does not believe that it will, incur debts beyond the
Company's ability to pay as such debts mature, and (b) the Company is not about
to engage in a transaction, after giving effect to which the Company's remaining
property would constitute unreasonably small capital for the business conducted
or transactions engaged by the Company.

        Except as specifically disclosed on Schedule 6.15, the Company and each

of the patents, trademarks, service marks, trade names, copyrights, contractual
franchises, authorizations and other rights that are reasonably necessary for
the operation of their respective businesses, without conflict with the rights
of any other Person, except where such conflict could not reasonably be expected
to have a Material Adverse Effect. To the best knowledge of the Company, no
slogan or other advertising device, product, process, method, substance, part or
other material now employed, or now contemplated to be employed, by the Company
or any Subsidiary of the Company infringes upon any rights held by any other
Person, except where such infringement could not reasonably be expected to have
a Material Adverse Effect. Except as specifically disclosed in Schedule 6.05, no
claim or litigation regarding any of the foregoing is pending or threatened, and
no patent, invention, device, application, principle or any statute, law, rule,
regulation, standard or code is pending or, to the best knowledge of the
Company, proposed, which, in either case, could reasonably be expected to have a
Material Adverse Effect.

        6.16   Subsidiaries.

        As of the Closing Date, the Company does not have any Subsidiaries other
than those specifically disclosed in part (a) of Schedule 6.16 hereto, which
shows the form of organization and ownership of each such Person and has no
equity investments in any other Person constituting in excess of 5% of the
outstanding equity of such Person other than those specifically disclosed in
part (b) of Schedule 6.16. As of the Closing Date, the Material Subsidiaries of
the Company are as listed in part (c) of Schedule 6.16.

        6.17   Insurance.

        Except as specifically disclosed in Schedule 6.17, the respective
Properties of the Company and its Subsidiaries are insured with financially
sound and reputable insurance companies not Affiliates of the Company or any of
its Subsidiaries, in such amounts, with such deductibles and covering such risks
as are customarily carried by companies engaged in similar businesses and owning
similar properties in localities where the Company or any of its Subsidiaries
operates.

        6.18   Swap Obligations.

        Neither the Company nor any of its Subsidiaries has incurred any
outstanding obligations under any Swap Contracts, other than Permitted Swap
Obligations. The Company and each of its Subsidiaries has voluntarily entered
into each Swap Contract to which each such Person is a party based upon each

                                       39
<PAGE>   45

such Person's own independent assessment of its consolidated assets, liabilities
and commitments, in each case as an appropriate means of mitigating and managing
risks associated with such matters, and has not relied on any swap counterparty
or any Affiliate of any swap counterparty in determining whether to enter into
any such Swap Contract.

        6.19   Full Disclosure.

        To the best knowledge after due inquiry of any Responsible Officer, none
of the representations or warranties made by the Company or any of its
Subsidiaries in the Credit Documents as of the date such representations and
warranties are made or deemed made, and none of the statements contained in any
exhibit, report, statement or certificate furnished by or on behalf of the
Company or any of its Subsidiaries in connection with the Credit Documents
(including any offering or disclosure materials delivered by or on behalf of the
Company to the Bank prior to the Closing Date), contains any untrue statement of
a material fact or omits any material fact required to be stated therein or
necessary to make the statements made therein, in light of the circumstances
under which they are made, not misleading as of the time when made or delivered.
It is recognized by the Bank that projections and forecasts provided by or on
behalf of the Company, although reflecting the Company's good faith projections
and forecasts based on methods and data which the Company believes to be
reasonable and accurate, are not to be viewed as facts and that actual results
during the period or periods covered by any such projections and forecasts may
(and are likely to) differ from the projected or forecasted results.

        6.20   Year 2000 Compliance.

               (a) The Company and each of its Subsidiaries have: (i) undertaken
a detailed inventory, review and assessment of all areas within their respective
businesses and operations that could be adversely affected by their respective
failure to be Year 2000 Compliant on a timely basis; and (ii) developed and are
implementing a detailed plan and timetable which reasonably assures that the
Company and each of its Subsidiaries will be Year 2000 Compliant by December 31,
1999. The products of the Company and its Subsidiaries do not address or utilize
dates in their operation and, accordingly, should not fail due to the year 2000
problem.

               (b) The Company and each of its Subsidiaries have made inquiry of
their respective key suppliers and vendors as to whether such Persons will be
Year 2000 Compliant by December 31, 1999 and, on the basis of such inquiry,
reasonably believe that (i) all such Persons will be so compliant or (ii) if any
of such Persons will not be so compliant, any such Person's failure to be Year
2000 Compliant could not reasonably be expected to have a Material Adverse
Effect.

        6.21   Good Standing Certificates.

        On or before the date that is five Business Days following the date of

date from the Secretary of State (or similar, applicable Governmental Authority)
of the States of Delaware, Georgia, Maryland, Minnesota, New Jersey,
Pennsylvania, Ohio and Texas.

and attorneys-in-fact (each, an "Indemnified Person") harmless from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements (including Attorney
Costs) of any kind or nature whatsoever which may at any time (including at any
time following repayment of the Loans) be imposed on, incurred by or asserted
against any such Person in any way relating to or arising out of this Agreement

contemplated hereby, or any action taken or omitted by any such Person under or
in connection with any of the foregoing, including with respect to any
investigation, litigation or proceeding (including any Insolvency Proceeding or
appellate proceeding) related to or arising out of this Agreement or the Loans
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

                                       59
<PAGE>   65

willful misconduct of such Indemnified Person. The agreements in this Section

                      (i) The Company hereby agrees to indemnify, defend and
        hold harmless each Indemnified Person, from and against any and all

        judgments, suits, costs, charges, expenses or disbursements (including
        Attorney Costs and the allocated cost of internal environmental audit or
        review services), which may be incurred by or asserted against such
        Indemnified Person in connection with or arising out of any pending or
        threatened investigation, litigation or proceeding, or any action taken
        by any Person, with respect to any Environmental Claim arising out of or
        related to any Property of the Company or any of its Subsidiaries. No
        action taken by legal counsel chosen by the Bank in defending against
        any such investigation, litigation or proceeding or requested remedial,
        removal or response action shall vitiate or any way impair the Company's
        obligation and duty hereunder to indemnify and hold harmless all
        Indemnified Persons.

                      (ii) In no event shall any site visit, observation, or
        testing by the Bank be deemed a representation or warranty that
        Hazardous Materials are or are not present in, on, or under the site, or
        that there has been or shall be compliance with any Environmental Law.
        Neither the Company nor any other Person is entitled to rely on any site
        visit, observation, or testing by the Bank. The Bank does not owe any
        duty of care to protect the Company or any other Person against, or to
        inform the Company or any other Person of, any Hazardous Materials or
        any other adverse condition affecting any site or Property. The Bank
        shall not be obligated to disclose to the Company or any other Person
        any report or findings made as a result of, or in connection with, any
        site visit, observation, or testing by the Bank.

               (c) Survival; Defense. The obligations in this Section 10.05
shall survive payment of all other Obligations. At the election of any

counsel satisfactory to such Indemnified Person in such Person's sole
discretion, at the sole cost and expense of the Company.

exercises its 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 agreed
to by the Bank in its sole discretion) to be repaid to a trustee, receiver or
any other party, in connection with any Insolvency Proceeding or otherwise,
then, 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.

        10.07  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 Bank

        10.08  Assignments, Participations, etc.

               (a) The Bank may at any time assign and delegate to one or more
Eligible Assignees (each an "Assignee") all or any part of the Loans, the L/C
Obligations, the Commitment and the other rights and obligations of the Bank
hereunder, in a minimum amount of $5,000,000; provided that the Company may
continue to deal solely and directly with the Bank in connection with the
interest so assigned to an Assignee until 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 by the Bank and
the Assignee.

               (b) The Bank may at any time sell to one or more commercial banks
or other Persons not Affiliates of the Company or any of its Subsidiaries (a
"Participant") participating interests in any Loans, L/C Obligations, the
Commitment of the Bank and the other interests of the Bank hereunder and under
the other Credit Documents; provided that the Bank shall not 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 Agreement or any
other Credit Document, except to the extent such amendment, consent or waiver
would (i) increase or extend the Commitment or subject to the Bank to any
additional obligations; (ii) postpone or delay any date fixed for any payment of
principal, interest, fees or other amounts due under any Credit Document; (iii)
reduce the principal of, or the rate of interest specified herein on any Loan or
L/C Advance or of any fees or other amounts payable under any Credit Document.
In the case of any such participation, the Participant shall not have any rights
under this Agreement, or any of the other Credit Documents, and all amounts
payable by the Company hereunder shall be determined as if the Bank had not sold
such participation, except that, 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 the Bank under this
Agreement. The Company shall not be required to incur any expense in connection
with any such participation.

               (c) Notwithstanding any other provision in this Agreement, the
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 Section 203.14, and such Federal Reserve
Bank may enforce such pledge or security interest in any manner permitted under
applicable law.

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 of its Subsidiaries under this Agreement or
any other Credit Document, and neither the Bank nor any of its Affiliates shall
use any such information other than in connection with or in enforcement of this
Agreement and the other Credit Documents or in connection with other business
now or hereafter existing or contemplated with the Company or any of its
Subsidiaries; 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 or its Subsidiaries, so long as such source is not bound by a
confidentiality agreement with the Company or any of its Subsidiaries known to
the Bank; provided that the 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 the 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

connection with any litigation or proceeding to which the Bank or any of its
Affiliates may be party; (E) to the extent reasonably required in connection
with the exercise of any remedy hereunder or under any other Credit Document;
(F) to the Bank's independent auditors and other professional advisors; (G) to
any Participant or Assignee, actual or potential, provided that such Person
agrees in writing to keep such information confidential to the same extent

Affiliates.

        10.10  Set-off.

        In addition to any rights and remedies of the Bank provided hereunder or
at law, if an Event of Default exists or the Obligations have been accelerated,
the 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, the Bank to or for the credit or the account
of the Company against any and all Obligations now or hereafter existing,
irrespective of whether or not the Bank shall have made demand under this
Agreement or any Credit Document and although such Obligations may be contingent
or unmatured. The Bank agrees to notify promptly the Company after any such
set-off and application made by the Bank, provided that the failure to give such
notice shall not affect the validity of such set-off and application.

SOLELY IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE UNITED STATES FOR THE
NORTHERN DISTRICT OF CALIFORNIA, AND, BY EXECUTION AND DELIVERY HEREOF, EACH OF
THE COMPANY AND THE BANK CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO

        10.15  Arbitration.

               (a) Upon the demand of any party, any Dispute shall be resolved
by binding arbitration (except as set forth in (e) below) in accordance with the
terms of this Agreement. A "Dispute" means any action, dispute, claim or
controversy of any kind, whether in contract or tort, statutory or common law,
legal or equitable, now existing or hereafter arising under or in connection
with, or in any way pertaining to, any of the Credit Documents, or any past,
present or future extensions of credit and other activities, transactions or
obligations of any kind related directly or indirectly to any of the Credit
Documents, including any of the foregoing arising in connection with the
exercise of any self-help, ancillary or other remedies pursuant to any of the
Credit Documents. Any party may by summary proceedings bring an action in court
to compel arbitration of a Dispute. Any party who fails or refuses to submit to
arbitration following a lawful demand by any other party shall bear all costs
and expenses incurred by such other party in compelling arbitration of any
Dispute.

               (b) Arbitration proceedings shall be administered by the American
Arbitration Association ("AAA") or such other administrator as the parties shall
mutually agree upon in accordance with the AAA Commercial Arbitration Rules. All
Disputes submitted to arbitration shall be resolved in accordance with the
Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any
conflicting choice of law provision in any of the Credit Documents. The
arbitration shall be conducted at a location in California selected by the AAA
or other administrator. If there is any inconsistency between the terms hereof
and any such rules, the terms and procedures set forth herein shall control. All
statutes of limitation applicable to any Dispute shall apply to any arbitration
proceeding. All discovery activities shall be expressly limited to matters
directly relevant to the Dispute being arbitrated. Judgment upon any award
rendered in an arbitration may be entered in any court having jurisdiction;
provided that nothing contained herein shall be deemed to be a waiver by any
party that is a bank of the protections afforded to it under 12 U.S.C. Section
91 or any similar applicable state law.

               (c) No provision hereof shall limit the right of any party to
exercise self-help remedies such as setoff, foreclosure against or sale of any
real or personal property collateral or security, or to obtain provisional or
ancillary remedies, including injunctive relief, sequestration, attachment,
garnishment or the appointment of a receiver, from a court of competent
jurisdiction before, after or during the pendency of any arbitration or other
proceeding. The exercise of any such remedy shall not waive the right of any
party to compel arbitration or reference hereunder.

<PAGE>   69

               (d) Arbitrators must be active members of the California State
Bar or retired judges of the state or federal judiciary of California, with
expertise in the substantive laws applicable to the subject matter of the
Dispute. Arbitrators are empowered to resolve Disputes by summary rulings in
response to motions filed prior to the final arbitration hearing. Arbitrators
(i) shall resolve all Disputes in accordance with the substantive law of the
state of California, (ii) may grant any remedy or relief that a court of the
state of California could order or grant within the scope hereof and such
ancillary relief as is necessary to make effective any award, and (iii) shall
have the power to award recovery of all costs and fees, to impose sanctions and
to take such other actions as they deem necessary to the same extent a judge
could pursuant to the Federal Rules of Civil Procedure, the California Rules of
Civil Procedure or other applicable law. Any Dispute in which the amount in
controversy is $5,000,000 or less shall be decided by a single arbitrator who
shall not render an award of greater than $5,000,000 (including damages, costs,
fees and expenses). By submission to a single arbitrator, each party expressly
waives any right or claim to recover more than $5,000,000. Any Dispute in which
the amount in controversy exceeds $5,000,000 shall be decided by majority vote
of a panel of three arbitrators; provided that all three arbitrators must
actively participate in all hearings and deliberations.

               (e) Notwithstanding anything to the contrary contained herein, in
any arbitration in which the amount in controversy exceeds $25,000,000, the
arbitrators shall be required to make specific, written findings of fact and
conclusions of law. In such arbitrations (i) the arbitrators shall not have the
power to make any award which is not supported by substantial evidence or which
is based on legal error, (ii) an award shall not be binding upon the parties
unless the findings of fact are supported by substantial evidence and the
conclusions of law are not erroneous under the substantive law of the state of
California, and (iii) the parties shall have in addition to the grounds referred
to in the Federal Arbitration Act for vacating, modifying or correcting an award
the right to judicial review of (A) whether the findings of fact rendered by the
arbitrators are supported by substantial evidence, and (B) whether the
conclusions of law are erroneous under the substantive law of the state of
California. Judgment confirming an award in such a proceeding may be entered
only if a court determines the award is supported by substantial evidence and
not based on legal error under the substantive law of the state of California.

               (f) Notwithstanding anything to the contrary contained herein, no
Dispute shall be submitted to arbitration if the Dispute concerns indebtedness
secured directly or indirectly, in whole or in part, by any real property unless
(i) the holder of the mortgage, lien or security interest specifically elects in
writing to proceed with the arbitration, or (ii) all parties to the arbitration
waive any rights or benefits that might accrue to them by virtue of the single
action rule statute of California, thereby agreeing that all indebtedness and
obligations of the parties, and all mortgages, liens and security interests
securing such indebtedness and obligations, shall remain fully valid and
enforceable. If any such Dispute is not submitted to arbitration, the Dispute
shall be referred to a referee in accordance with California Code of Civil
Procedure Section 638 et seq., and this general reference agreement is intended
to be specifically enforceable in accordance with said Section 638. A referee
with the qualifications required herein for arbitrators shall be selected
pursuant to the AAA's selection procedures. Judgment upon the decision rendered
by a referee shall be entered in the court in which such proceeding was
commenced in accordance with California Code of Civil Procedure Sections 644 and
645.

               (g) To the maximum extent practicable, the AAA, the arbitrators
and the parties shall take all action required to conclude any arbitration
proceeding within 180 days of the filing of the Dispute with the AAA. No
arbitrator or other party to an arbitration proceeding may disclose the
existence, content or results thereof, except for disclosures of information by
a party required in the ordinary course of its business, by applicable law or
regulation, or to the extent necessary to exercise any

                                       64
<PAGE>   70

judicial review rights set forth herein. If more than one agreement for
arbitration by or between the parties potentially applies to a Dispute, the
arbitration provision most directly related to the Credit Documents or the
subject matter of the Dispute shall control. This arbitration provision shall
survive termination, amendment or expiration of any of the Credit Documents or
any relationship between the parties.

        10.16  Entire Agreement.

        This Agreement, together with the other Credit Documents, embodies the
entire agreement and understanding among the Company and the Bank and supersedes
all prior or contemporaneous agreements and understandings of such Persons,
verbal or written, relating to the subject matter hereof and thereof.
