                 2.6  Reductions of Commitments.  The Company shall have the
right, at any time and from time to time, to terminate in whole or permanently
reduce in part, without premium or penalty, the Commitments; provided, that the
Aggregate Commitment, as reduced, shall at all times be equal to or exceed the
sum of the outstanding principal amount of all Loans.  The Company shall give
not less than five Business Days' prior written notice to the Agent designating
the date (which shall be a Business Day) of such termination or reduction and
the amount of any partial reduction.  Promptly after receipt of a notice of
such termination or partial reduction, the Agent shall notify each Bank of the
proposed termination or reduction.  Such termination or partial reduction of
the Commitments shall be effective on the date specified in the Company's
notice and shall terminate or reduce each Bank's Pro Rata share of the
Aggregate Commitment so reduced.  Any partial reduction shall be in an
aggregate minimum amount of $5,000,000.

                 2.7  Interest on the Loans.

                 (a)  Subject to Section 2.7(c), the Loans shall bear interest
on the unpaid principal amount thereof from the Borrowing Date to maturity
(whether by acceleration or otherwise) at a rate per annum equal to either the
Offshore Rate plus the Offshore Applicable Margin, as the same may be adjusted
pursuant to the definition of Offshore Applicable Margin, or the Base Rate.

                 (b)  Interest shall be payable in arrears on the Loans on each
Interest Payment Date applicable to that Loan.

                 (c)  Any principal payments on the Loans not paid when due
and, to the extent permitted by applicable law, any interest payments on the
Loans not paid when due, in each case whether at stated maturity, by notice of
prepayment, by acceleration or otherwise, shall thereafter bear interest
payable upon demand at a rate which is equal to the Base Rate plus 2% per
annum.

                 2.8  Maturity of Loans.  Each Loan shall mature and the
Company shall repay the unpaid principal amount of each Loan on the Maturity
Date.

                 2.9  Voluntary Prepayments. The Company may, upon not less
than one Business Days' prior written or telephonic notice confirmed in writing
to the Agent (in the case of a prepayment of a Base Rate Loan) or three
Business Days' prior written or telephonic notice confirmed in writing to the
Agent (in the case







                                       20
<PAGE>   25
of a prepayment of a Offshore Rate Loan) (which notice the Agent will promptly
transmit to each Bank), at any time and from time to time prepay any Loans in
whole or in part in an aggregate minimum amount of $5,000,000 and integral
multiples of $1,000,000 in excess of that amount; provided that in the event of
any such prepayment of any Offshore Rate Loans, the Company shall be obligated
to reimburse the Banks in respect thereof pursuant to Section 3.6.  If such
notice of prepayment does not specify how such prepayment shall be applied, it
shall be applied first to Base Rate Loans to the full extent thereof before
application to Offshore Rate Loans, as determined by the Agent.  All
prepayments shall be applied to the payment of any interest that is due and
payable at the time of such prepayment before application to principal.

                 2.10  Fees.

                 (a)      Arrangement Fee.  The Company shall pay to Bank of
America for Bank of America's own account an arrangement fee in an amount and
at the times set forth in a letter agreement between the Company and Bank of
America dated the Closing Date.

                 (b)      Facility Fees.  The Company shall pay to the Agent a
facility fee on the Aggregate Commitment, computed on a quarterly basis in
arrears on the last Business Day of each calendar quarter, equal to 0.06% per
annum to be distributed to each Bank in accordance with its Pro Rata Share.
Such facility fee shall accrue from the Closing Date to the Maturity Date and
shall be due and payable quarterly in arrears on the last Business Day of each
calendar quarter and on the Maturity Date; provided that, in connection with
any reduction or termination of Commitments pursuant to Section 2.6, the
accrued facility fee calculated for the period ending on such date shall also
be paid on the date of such reduction or termination, with the next succeeding
quarterly payment being calculated on the basis of the period from the
reduction or termination date to such quarterly payment date.  The facility
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 Section 4 are not
met.

                 (c)      Agency Fee.  The Company shall pay to the Agent for
the Agent's own account an agency fee in the amount and at the times set forth
in a letter agreement between the Company and the Agent dated the Closing Date.

                 2.11  Computation of Fees and Interest.  All computations of
interest payable in respect of Base Rate Loans







                                       21
<PAGE>   26
and all fees shall be made on the basis of a year of 365 or 366 days, as the
case may be, and actual days elapsed.  All computations of interest payable in
respect of Offshore Rate Loans 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.

                 2.12  Use of Proceeds of Loans.  The Company shall use the
proceeds of Loans for general corporate purposes.

                 2.13  Extension of Maturity Date.  The Company may request
that the Banks extend the Maturity Date for successive 364 day periods by
notifying the Banks in writing through the Agent not more than 60 days nor less
than 30 days prior to the Maturity Date, then in effect.  The Agent shall
promptly notify each Bank of such an extension request.  Thereupon, the parties
hereto shall commence good faith negotiations as to the terms and conditions of
the proposed extension which shall include a full credit assessment of the
Company by the Banks.  Each Bank shall have the right to consent to or reject
such extension request in the exercise of its sole and absolute discretion and
shall notify the Agent of its decision not more than 20 days after receipt of
such extension request from the Agent.  Failure by any Bank to notify the Agent
of its decision shall be deemed to be a rejection by such Bank of the extension
request.  If all Banks consent to such extension, the Maturity Date shall be
extended for 364 days from the then current Maturity Date.


                 Section 3.  PAYMENTS IN GENERAL.

                 3.1  Taxes.

                 (a)      Subject to Section 3.1(g), any and all payments by
the Company to each Bank or the Agent under this Agreement shall be made free
and clear of, and without deduction or withholding for, any and all present or
future taxes, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Bank and the
Agent, such taxes (including income taxes or franchise taxes) as are imposed on
or measured by each Bank's net income by the jurisdiction under the laws of
which such Bank or the Agent, as the case may be, is organized or maintains a
Lending Office or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deductions, charges, withholdings and liabilities being
hereinafter referred to as "Taxes").







                                       22
<PAGE>   27
                 (b)      In addition, the Company shall pay any present or
future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or from
the execution, delivery or registration of, or otherwise with respect to, this
Agreement or any other Loan Documents (hereinafter referred to as "Other
Taxes").

                 (c)      Subject to Section 3.1(g), the Company shall
indemnify and hold harmless each Bank and the Agent for the full amount of
Taxes or Other Taxes (including without limitation, any Taxes or Other Taxes
imposed by any jurisdiction on amounts payable under this Section 3.1) paid by
the Bank or the Agent and any liability (including penalties, interest,
additions to tax and expenses to the extent not resulting from the gross
negligence or wilful misconduct of a Bank or the Agent) arising therefrom or
with respect thereto, whether or not such Taxes or Other Taxes were correctly
or legally asserted.  Payment under this indemnification shall be made within
30 days from the date the Bank or the Agent makes written demand therefor.

                 (d)      If the Company shall be required by law to deduct or
withhold any Taxes or Other Taxes from or in respect of any sum payable
hereunder to any Bank or the Agent, then, subject to Section 3.1(g): (i) the
sum payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section 3.1) such Bank or the Agent, as the case may be, receives an
amount equal to the sum it would have received had no such deductions been
made; (ii) the Company shall make such deductions, and (iii) the Company shall
pay the full amount deducted to the relevant taxation authority or other
authority in accordance with applicable law.

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

                 (f)      Each Bank which is a foreign Person (i.e., a Person
other than a United States Person for United States Federal income tax
purposes) agrees that:  (i) it shall, no later than the Closing Date (or, in
the case of a Bank which becomes a party hereto pursuant to Section 10.6 after
the Closing Date, the date upon which the Bank becomes a party hereto) deliver
to the







                                       23
<PAGE>   28
Company through the Agent:  (A) if any Lending Office is located in the United
States, two accurate and complete signed originals of Internal Revenue Service
Form 4224 or any successor thereto ("Form 4224"), and (B) if any Lending Office
is located outside the United States, two accurate and complete signed
originals of Internal Revenue Service Form 1001 or any successor thereto ("Form
1001"), in each case indicating that the Bank is on the date of delivery
thereof entitled to receive payments of principal, interest and fees for the
account of such Lending Office or Offices under this Agreement free from
withholding of United States Federal income tax; (ii) if at any time the Bank
changes its Lending Office or Offices or selects an additional Lending Office
as herein provided, it shall with reasonable promptness deliver to the Company
through the Agent in replacement for, or in addition to, the forms previously
delivered by it hereunder:  (A) if such changed or additional Lending Office is
located in the United States, two accurate and complete signed originals of
Form 4224; or (B) otherwise, two accurate and complete signed originals of Form
1001, in each case indicating that the Bank is on the date of delivery thereof
entitled to receive payments of principal, interest and fees for the account of
such changed or additional Lending Office under this Agreement free from
withholding of United States Federal income tax; (iii) it shall, before or
promptly after the occurrence of any event (including the passing of time but
excluding any event mentioned in (ii) above) requiring a change in the most
recent Form 4224 or Form 1001 previously delivered by such Bank and if the
delivery of the same be lawful, deliver to the Company through the Agent two
accurate and complete original signed copies of Form 4224 or Form 1001 in
replacement for the forms previously delivered by the Bank; and (iv) it shall,
promptly upon the Company's reasonable request to that effect, deliver to the
Company such other forms or similar documentation as may be required from time
to time by any applicable law, treaty, rule or regulation in order to establish
such Bank's tax status for withholding purposes.

                 (g)      The Company will not be required to pay any
additional amounts in respect of United States Federal income tax pursuant to
Section 3.1(d) to any Bank for the account of any Lending Office of such Bank:
(i) if the obligation to pay such additional amounts would not have arisen but
for a failure by such Bank to comply with its obligations under Section 3.1(f)
in respect of such Lending Office; (ii) if such Bank shall have delivered to
the Company a Form 4224 in respect of such Lending Office pursuant to Section
3.1(f)(i)(A), and such Bank shall not at any time be entitled to exemption from
deduction or







                                       24
<PAGE>   29
withholding of United States Federal income tax in respect of payments by the
Company hereunder for the account of such Lending Office after the date of
delivery of such Form 4224; or (iii) if the Bank shall have delivered to the
Company a Form 1001 in respect of such Lending Office pursuant to Section
3.1(f)(i)(B), and such Bank shall not at any time be entitled to exemption from
deduction or withholding of United States Federal income tax in respect of
payments by the Company hereunder for the account of such Lending Office after
the date of delivery of such Form 1001.

                 (h)      If, at any time, the Company requests any Bank to
deliver any forms or other documentation pursuant to Section 3.1(f)(iv), then
the Company shall, on demand of such Bank through the Agent, reimburse such
Bank for any costs and expenses (including expenses of outside legal counsel
and the allocated costs of in-house counsel) reasonably incurred by such Bank
in the preparation or delivery of such forms or other documentation.

                 (i)      If the Company is required to pay additional amounts
to any Bank or the Agent pursuant to Section 3.1(d), then such Bank shall use
its reasonable best 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 judgment of such Bank is not otherwise disadvantageous to such Bank.

                 (j)      The agreements and obligations of the Company
contained in this Section 3.1 shall survive the payment in full of all other
Obligations.

                 3.2  Payments by the Company.  All payments of principal,
interest and fees hereunder shall be in the same day funds and delivered to the
Agent for credit to:

                          Bank of America National Trust
                          and Savings Association

for the account of the Banks not later than 10:00 A.M. (San Francisco time) on
the date due; funds received by the Agent after that time shall be deemed to
have been paid by the Company on the next succeeding Business Day.







                                       25
<PAGE>   30
                 3.3  Payments on Non-Business Days.  Whenever any payment to
be made hereunder shall be stated to be due on a day which is not a Business
Day, the payment shall be made on the next succeeding Business Day and such
extension of time shall be included in the computation of the payment of the
interest hereunder; provided that, in the event that the day on which payment
relating to a Offshore Rate Loan is due is not a Business Day but is a day of
the month after which no further Business Day occurs in that month, then the
due date thereof shall be the next preceding Business Day and such shortening
of time shall be excluded in the computation of the payment of the interest
hereunder.

                 3.4  Illegality.

                 (a)      If any Bank shall determine that the introduction of
any Requirement of Law or any change in or in the interpretation or
administration thereof has made it unlawful, or that any central bank or other
Governmental Authority has asserted that it is unlawful, for any Bank or its
Lending Office to make Offshore Rate Loans, then, on notice thereof by the Bank
to the Company through the Agent, the obligation of the Bank to make Offshore
Rate Loans shall be suspended until the Bank shall have notified the Agent and
the Company that the circumstances giving rise to such determination no longer
exists.

                 (b)      If a Bank shall determine that it is unlawful to
maintain any Offshore Rate Loan, the Company shall prepay in full all Offshore
Rate Loans of the Bank then outstanding, together with interest accrued
thereon, either on the last day of the Interest Period thereof if the Bank may
lawfully continue to maintain such Offshore Rate Loans to such day, or
promptly, if the Bank may not lawfully continue to maintain such Offshore Rate
Loans, together with any amounts required to be paid in connection therewith
pursuant to Section 3.6.

                 (c)      If the Company is required to prepay any Offshore
Rate Loans immediately as provided in Section 3.4(b), then concurrently with
such prepayment, the Company shall borrow from the affected Bank, in the amount
of such repayment, a Base Rate Loan.

                 (d)      Before giving any notice to the Agent pursuant to
this Section 3.4, the affected Bank shall designate a different Lending Office
with respect to its Offshore Rate Loans if such designation will avoid the need
for giving such notice or making such demand and will not, in the judgment of
the Bank, be illegal or otherwise disadvantageous to the Bank.







                                       26
<PAGE>   31
                 3.5  Increased Costs and Reduction of Return.  (a)  If any
Bank shall determine that, due to either (i) the introduction of or any change
in or in the interpretation of any law or regulation or (ii) the compliance
with any guideline or request from any central bank or other Governmental
Authority (whether or not having the force of law), there shall be any increase
in the cost to such Bank of agreeing to make or making, funding or maintaining
any Offshore Rate Loans, then the Company shall be liable for, and shall from
time to time, upon demand therefor by such Bank (with a copy of such demand to
the Agent), pay to such Bank, additional amounts as are sufficient to
compensate such Bank for such increased costs.

                 (b)      If any Bank shall have determined that the
introduction of any applicable law, rule, regulation or guideline regarding
capital adequacy, or any change therein or any change in the interpretation or
administration thereof by any central bank or other Governmental Authority
charged with the interpretation or administration thereof, or compliance by the
Bank (or its Lending Office) or any corporation controlling the Bank, with any
request, guideline or directive regarding capital adequacy (whether or not
having the force of law) of any such central bank or other authority, affects
or would affect the amount of capital required or expected to be maintained by
the Bank or any corporation controlling the Bank and (taking into consideration
such Bank's or such corporation's policies with respect to capital adequacy and
such Bank's desired return on capital) determines that the amount of such
capital is increased as a consequence of its obligation under this Agreement,
then, upon demand of such Bank, the Company shall immediately pay to the Bank,
from time to time as specified by the Bank, additional amounts sufficient to
compensate the Bank for such increase.

                 3.6  Funding Losses.  The Company agrees to reimburse each
Bank and to hold each Bank harmless from any loss or expense which the Bank may
sustain or incur as a consequence of:  (a) the failure of the Company to make
any payment or prepayment of principal of any Offshore Rate Loan (including
payments made 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 after the Company has
given a notice in accordance with Section 2.9; or (d) the prepayment of a
Offshore Rate Loan on a day which is not the last day of the Interest Period
with







                                       27
<PAGE>   32
respect thereto; including any such loss or expense arising from the
liquidation or reemployment of funds obtained by it to maintain its Offshore
Rate Loans hereunder or from fees payable to terminate the deposits from which
such funds were obtained.  This covenant shall survive the payment in full of
all other Obligations.

                 3.7  Inability to Determine Rates.  If Bank of America advises
the Agent that it shall have determined that for any reason adequate and
reasonable means do not exist for ascertaining the Offshore Rate for any
requested Interest Period with respect to a proposed Offshore Rate Loan, or if
the Requisite Banks advise the Agent that the Offshore Rate applicable for any
requested Interest Period does not adequately and fairly reflect the cost to
such Banks of funding an Offshore Rate Loan, the Agent shall forthwith give
notice of such determination to the Company and each Bank.  Thereafter, the
obligation of the Banks to make or maintain Offshore Rate Loans, as the case
may be, hereunder shall be suspended until the Agent upon the instruction of
the Requisite Banks revokes such notice in writing.  Upon receipt of such
notice, the Company may revoke any Notice of Borrowing or Notice of Conversion/
Continuation then submitted by it.  If the Company does not revoke such notice
with respect to Loans, the Banks shall make, convert or continue the Loans, as
proposed by the Company, in the amount specified in the applicable notice
submitted by the Company, but such Loans shall be made, converted or continued
as Base Rate Loans instead of Offshore Rate Loans.

                 3.8  Payments by Banks.   Unless the Agent shall have received
notice from a Bank at least one Business Day prior to the date of any proposed
Borrowing (or, with respect to Borrowings comprised of Base Rate Loans, prior
to the Agent funding such Borrowing on such Borrowing Date) that such Bank will
not make available to the Agent for the account of the Company the amount of
that Bank's Loan, the Agent may assume that each Bank has made such amount
available to the Agent on the Borrowing date and the Agent may (but shall not
be so required), in reliance upon such assumption, make available to the
Company on such date a corresponding amount.  If and to the extent any Bank
shall not have made its full amount available to the Agent and the Agent in
such circumstances has made available to the Company such amount, that Bank
shall within two Business Days following the date of such Borrowing make such
amount available to the Agent, together with interest at the Federal Funds Rate
for each day during such period.  A certificate of the Agent submitted to any
Bank with respect to amounts owing under this







                                       28
<PAGE>   33
Section 3.8 shall be conclusive, absent manifest error.  If such amount is so
made available, such payment to the Agent shall constitute such Bank's Loan on
the date of Borrowing for all purposes of this Agreement.  If such amount is
not made available to the Agent within two Business Days following the date of
such Borrowing, the Agent shall notify the Company of such failure to fund and,
upon demand by the Agent, the Company shall pay such amount to the Agent for
the Agent's account, together with interest thereon for each day elapsed since
the date of such Borrowing, at a rate per annum equal to the interest rate
applicable at the time to such Loan.

                 Section 5.  REPRESENTATIONS AND WARRANTIES

                 The Company represents and warrants to the Agent and each Bank
that:

                 5.1  Corporate Existence and Power.  The Company and each of
its Subsidiaries:  (a) is a corporation duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation; (b) has
the power and authority and all governmental licenses, authorizations, consents
and approvals to own its assets, carry on its business and to execute, deliver
and perform its obligations under the Loan Documents; (c) is duly qualified as
a foreign corporation, licensed and in good standing under the laws of each
jurisdiction where its ownership, lease or operation of property or the conduct
of its business requires such qualification; and (d) is in material compliance
with all Requirements of Law.

                 5.2  Corporate Authorization; No Contravention.  The
execution, delivery and performance by the Company of this Agreement and any
other Loan Document have been duly authorized by all necessary corporate action
and do not and will not:  (a) contravene the terms of the Company's certificate
of incorporation, bylaws or other organization document; (b) conflict with or
result in any breach or contravention of, or the creation of any Lien under,
any indenture, agreement, lease,







                                       31
<PAGE>   36
instrument, Contractual Obligation, injunction, order, decree or undertaking to
which the Company is a party; or (c) violate any material Requirement of Law.

                 5.3  Governmental Authorization.  No approval, consent,
exemption, authorization, or other action by, or notice to, or filing with, any
Governmental Authority is necessary or required in connection with the
execution, delivery, performance or enforcement against the Company of the
Agreement or any other Loan Document or any other instrument or agreement
required hereunder to be made by the Company.

                 5.4  Binding Effect.  This Agreement and each other Loan
Document to which the Company is a party constitute the legal, valid and
binding obligations of the Company, enforceable against the Company in
accordance with their respective terms, except as enforceability may be limited
by applicable bankruptcy, insolvency, or similar laws affecting the enforcement
of creditors' rights generally or by equitable principles relating to
enforceability.

                 5.5  Litigation.  Except as disclosed in the Company's Annual
Report on Form 10-K for the year ending August 31, 1997 and in the Company's
Quarterly Reports on Form 10-Q for the quarters ending November 30, 1997,
February 28, 1998 and May 31, 1998, as filed with the Securities and Exchange
Commission, there are no actions, suits, proceedings, claims or disputes
pending, or to the best knowledge of the Company, threatened or contemplated at
law, in equity, in arbitration or before any Governmental Authority, against
the Company, or its Subsidiaries or any of their respective properties which:
(a) purport to affect or pertain to this Agreement, or any Loan Document, or
any of the transactions contemplated hereby or thereby; or (b) if determined
adversely to the Company, or its Subsidiaries, might have a Material Adverse
Effect.  No injunction, writ, temporary restraining order or any order of any
nature has been issued by any court or other Governmental Authority purporting
to enjoin or restrain the execution, delivery and performance of this Agreement
or any other Loan Document, or directing that the transactions provided for
herein or therein not be consummated as herein or therein provided.

                 5.6  No Default.  No Default or Event of Default exists or
would result from the incurring of obligations by the Company under this
Agreement or any other Loan Document.  Neither the Company, nor any of its
Subsidiaries, is in default under or with respect to any Contractual Obligation
in any respect which,







                                       32
<PAGE>   37
individually or together with all such defaults, could have a reasonable
likelihood of having a Material Adverse Effect.

                 5.7  ERISA Compliance.  Each of the Company and the ERISA
Affiliates has fulfilled its obligations under the minimum funding standards of
ERISA and the Code with respect to each Plan and are in compliance with all
material respects with the presently applicable provisions of ERISA and the
Code, and have not incurred any liability to the PBGC or any Plan or
Multiemployer Plan.

                 5.8  Use of Proceeds; Margin Regulations.  The proceeds of the
Loans shall be used solely for the purposes set forth in Sections 2.12.  No
portion of the Loans will be used, directly or indirectly, (i) to purchase or
carry Margin Stock or (ii) to repay or otherwise refinance Indebtedness of the
Company or others incurred to purchase or carry Margin Stock, or (iii) to
extend credit for the purpose of purchasing or carrying any Margin Stock. No
proceeds of any Loans will be used to acquire any security in any transaction
which is subject to Section 13 or 14 of the Exchange Act.

                 5.9  Title to Properties.  The Company and each of its
Subsidiaries has good record and marketable title in fee simple to or valid
leasehold interests in all its property, except for such defects in title as
could not, individually or in the aggregate, have a Material Adverse Effect.
The property is free and clear of all Liens or rights of others, except
Permitted Liens.

                 5.10  Taxes.  The Company and its Subsidiaries have filed all
Federal and other material tax returns and reports required to be filed and
have paid all Federal and other material  taxes, assessments, fees and other
governmental charges levied or imposed upon them or their properties, income or
assets otherwise due and payable except those which are being contested in good
faith by appropriate proceedings and for which adequate reserves have been
provided in accordance with GAAP and no Notice of Lien has been filed or
recorded. There is no proposed tax assessment against the Company or any of its
Subsidiaries which would, if the assessment were made, have a Material Adverse
Effect.

                 5.11  Financial Condition.

                 (a)      The audited consolidated financial statements of
financial condition of the Company and its Subsidiaries dated August 31, 1997,
and the related consolidated statements of







                                       33
<PAGE>   38
operations, stockholders' equity and cash flows for the fiscal year ended on
that date:  (i) were prepared in accordance with GAAP consistently applied
throughout the period covered thereby, except as otherwise expressly noted
therein; (ii) are complete, accurate and fairly present the financial condition
of the Company and its Subsidiaries as of the date thereof and results of
operations for the period covered thereby; and (iii) show all material
Indebtedness and other liabilities of the Company and its consolidated
Subsidiaries as of the date thereof (including liabilities for taxes and
material commitments).

                 (b)      Since August 31, 1997,  there has been no Material
Adverse Effect.

                 (c)      Schedule 5.11 sets forth all material contingent
obligations of the Company as of the Closing Date.

                 5.12  Environmental Matters.  The operations of the Company
and each of its Subsidiaries comply in all material respects with all
Environmental Laws.  The Company and each of its Subsidiaries has obtained all
licenses, permits, authorizations and registrations required under any
Environmental Law ("Environmental Permits") necessary for its operations, and
all such Environmental Permits are in good standing, and the Company and each
of its Subsidiaries is in compliance with all terms and conditions of such
Environmental Permits.  There are no conditions or circumstances which may give
rise to any Environmental Claim arising from the operations of the Company or
its Subsidiaries, including Environmental Claims associated with any operations
of the Company or its Subsidiaries with a potential liability in excess of
$10,000,000 in the aggregate.  Without limiting the generality of the
foregoing, the Company and its Subsidiaries have notified all of their
employees of the existence, if any, of any health hazard arising from the
conditions of their employment and have met all notification requirements under
Title III of CERCLA or any other Environmental Law.

                 5.13  Regulated Entities.  None of the Company, any Person
controlling the Company, or any Subsidiaries of the Company, is (a) an
"Investment Company" within the meaning of the Investment Company Act of 1940;
or (b) 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.







                                       34
<PAGE>   39
                 5.14  No Burdensome Restrictions.  Neither the Company, nor
any of its Subsidiaries is a party to or bound by any Contractual Obligation or
subject to any charter or corporate restriction or any Requirement of Law which
could reasonably be expected to have a Material Adverse Effect.

                 5.15  Insurance.  The properties of the Company and its
Subsidiaries are insured with financially sound and reputable insurance
companies or self-insured, in such amounts, with such deductibles and covering
such risks as is customarily carried on by companies engaged in similar
businesses and owning similar properties in localities where the Company or
such Subsidiary operates.

                 5.16  Full Disclosure.  None of the representations or
warranties made by the Company or any of its Subsidiaries in the Loan Documents
as of the date of such representations and warranties, and none of the
statements contained in each exhibit, report, statement or certificate
furnished by or on behalf of the Company or any of its Subsidiaries in
connection with the Loan Documents, 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.

                 5.17  Year 2000.  The Company has developed and implemented a
comprehensive, detailed program to address on a timely basis the "Year 2000
problem" (that is, the risk that computer applications used by the Company may
be unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date after December 31, 1999) and reasonably
anticipates that it will on a timely basis successfully resolve the Year 2000
problem for all material computer applications used by it.  The Company, on the
basis of inquiry made, believes that each supplier, vendor and customer of the
Company that is of material importance to the financial well-being of the
Company will also successfully resolve on a timely basis the Year 2000 problem
for all of its material computer applications.

Subsidiary has not assumed or become obligated to repay directly or

Capitalization of the Company and its Subsidiaries.

nor shall it permit any of its Subsidiaries to, consolidate with or merge into
any other corporation or convey, transfer or lease its properties and assets

and the Company shall not permit any Person to consolidate with or merge into

<PAGE>   47
Subsidiary at the time of such transaction, no Event of Default or Default
shall have happened and be continuing;

                 (c)      if, as a result of any such consolidation or merger

the Company or such successor corporation or Person, as the case may be, shall
take such steps as shall be necessary effectively to secure the Obligations
equally and ratably with all Indebtedness secured thereby; and

                 (d)      the Company has delivered to the Agent a certificate
signed by a Responsible Officer and an Opinion of Counsel, each stating that
such consolidation, merger, conveyance, transfer or lease complies with this

such transaction have been complied with, and such certificate shall
additionally state that, in the opinion of the board of directors of the
Company, the transaction is in the interest of the Company and not

the merger or consolidation of any Subsidiary with or into the Company or any
other Subsidiary, or the conveyance, transfer or lease of the properties and
assets of any Subsidiary substantially as an entirety (measured on a
consolidated basis) to any other Subsidiary, if the requirements of subsection

Responsible Officer and an Opinion of Counsel, each stating that such
consolidation, merger, conveyance, transfer or lease complies with this Section

convey or transfer any assets to a Subsidiary for the purpose of improving the
credit position of such Subsidiary in order to enable it to borrow money.

                 Upon any consolidation by the Company with or merger by the
Company into any other corporation or any conveyance, transfer or lease of the
properties and assets of the Company substantially as an entirety to any Person
in accordance with this Section 7.2, the successor corporation formed by such
consolidation or into which the Company is merged or to which such conveyance,
transfer or lease is made shall succeed to, and be substituted for, and may
exercise every right and power of, the Company under this Agreement with the
same effect as if such







                                       43
<PAGE>   48
successor corporation had been named as the Company herein, and thereafter,

7.3 if at the time of, and after giving effect to, such extensions of credit
and investments, the aggregate book value of all such extensions of credit and
investments not otherwise permitted hereby does not exceed $5,000,000 in the
aggregate.

                 7.4      Compliance with ERISA.  The Company shall not 
directly or indirectly and shall not permit any ERISA Affiliate directly or

result in any material (in the opinion of the Requisite Banks) liability to the
Company or any ERISA Affiliate, (ii) to permit to exist any ERISA Event or any
other event or condition, which presents the risk of a material (in the 








                                       44
<PAGE>   49

opinion of the Requisite Banks) liability of the Company or any ERISA
Affiliate, or (iii) to make a complete or partial withdrawal (within the
meaning of ERISA Section 4201) from any Multiemployer Plan so as to result in
any material (in the opinion of the Requisite Banks) liability to the Company
or any ERISA Affiliate, (iv) to enter into any new Plan or modify any existing
Plan so as to increase its obligations thereunder except in the ordinary course
of business consistent with past practice which could result in any material
(in the opinion of the Requisite Banks) liability to the Company or any ERISA
Affiliate, or (v) permit the present value of all nonforfeitable accrued
benefits under each Plan (using the actuarial assumptions utilized by the PBGC
upon termination of a Plan) materially (in the opinion of the Requisite Banks)
to exceed the fair market value of Plan assets allocable to such benefits, all
determined as of the most recent valuation date for each such Plan.

                 7.5      Restricted Payments.  The Company covenants that it
will not (a) declare or pay any dividend (other than dividends payable in
common stock of the Company) or make any other distribution on any shares of
capital stock of the Company of any class or (b) purchase, redeem or otherwise
acquire or retire for value, either directly or indirectly (other than in
exchange for or from the proceeds of other shares of capital stock of the
Company), any shares of capital stock of the Company of any class, if the
aggregate amount so declared, paid, distributed or expended after August 31,
1991 would exceed the aggregate amount of the consolidated net income of the
Company and its Subsidiaries accumulated after August 31, 1991 plus
$125,000,000; provided, however, that the Company may declare or pay dividends
or make other distributions on any class or series of preferred stock of the
Company and may purchase or retire for a consideration any shares thereof to
the extent required to comply with any sinking or purchase fund established
therefor, but all amounts so declared, paid, distributed or expended shall be
included in all subsequent computations pursuant to this Section 7.5.  The term
"stock" as used in this Section 7.5 shall include warrants, rights and options
to purchase stock.

Company shall not create, make, incur, assume, issue or guarantee, directly or
indirectly, any Senior Funded Indebtedness unless the Consolidated Net Tangible
Assets of the Company shall be at least equal to 150% of Consolidated Senior
Funded Indebtedness, after giving effect to the receipt and application of the
proceeds of any such Senior Funded Indebtedness proposed to be created, made,
incurred, assumed, issued or guaranteed, all







                                       45
<PAGE>   50
as shown by the consolidated balance sheet of the Company and its Subsidiaries
as of a date not more than 90 days prior to the proposed transaction (but
giving effect thereto), prepared as hereinafter provided.  Said balance sheet
shall be prepared by the Company on the basis of the latest available
consolidated balance sheet of the Company and its Subsidiaries on which a
report has been issued by a firm of certified or public accountants of
recognized national standing (which balance sheet as to which such a report has
been issued shall be as of a date not more than twelve months prior to the date
of such consolidated balance sheet), adjusted to reflect the proposed
transaction on a pro forma basis as well as to reflect transactions which shall
have occurred between the date of said balance sheet.

                 7.7  Change in Business.  The Company shall not, and shall not
permit any of its Subsidiaries to, engage in any material line of business
substantially different from those lines of business carried on by it on the

                 (e)      The Company or any of its Subsidiaries (i) fails to

beneficiaries of such Indebtedness (or a trustee or agent on behalf of such
holder or holders or beneficiary or beneficiaries) to cause such Indebtedness
to be declared to be due and payable prior to its stated maturity, or any

vacated or fully bonded within 60 days after commencement, filing or levy; or

                 (h)      An event or condition specified in Section 7.4 shall
occur or exist with respect to any Plan or Multiemployer







                                       47
<PAGE>   52
Plan and, as a result of such event or condition, together with all other such
events or conditions, the Company or any ERISA Affiliate shall incur or in the
opinion of the Requisite Banks shall be reasonably likely to incur a liability
to a Plan, a Multiemployer Plan or the PBGC (or any combination of the
foregoing) which is in the determination of the Requisite Banks, material in
relation to the consolidated financial position of the Company and the
Consolidated Subsidiaries; or

                 8.2  Remedies.  If any Event of Default occurs, the Agent
shall, at the request of, or may, with the consent of, the Requisite Banks, (a)

such Commitments shall forthwith be terminated; (b) declare the unpaid
principal amount of all outstanding Loans, all interest accrued and unpaid
thereon and all other amounts payable hereunder to be immediately due and
payable, without presentment, demand, protest or other notice of any kind, all
of which are hereby expressly waived by the Company; (c) exercise all rights
and remedies available to it under the Loan Documents or applicable law;
provided, however, that upon the occurrence of any event specified in Section

the 60 day period mentioned therein), the obligation of each Bank to make Loans
shall automatically terminate and the unpaid principal amount of all
outstanding Loans and all interest and other amounts as aforesaid shall
automatically become due and payable without further act of the Agent or any
Bank.

                 8.3  Rights Not Exclusive.  The rights provided for in this

                 Section 9.  THE AGENT

                 9.1  Appointment and Authorization.  Each Bank hereby
irrevocably appoints, designates and authorizes the Agent to take such action
on its behalf under the provisions of this Agreement and each other Loan
Document and to exercise such powers and perform such duties as are expressly
delegated to it by the terms of this Agreement or any other Loan Document,
together with such powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary contained elsewhere in this
Agreement or in any other Loan Document, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Bank, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or any other Loan Document or otherwise exist against the Agent.

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

                 9.3  Liability of Agent.  None of the Agent, its Affiliates,
or any of their respective officers, directors, employees, agents, or
attorneys-in-fact (collectively, the "Agent-Related Persons") shall (i) be
liable for any action taken or omitted to be taken by any of them under or in
connection with this Agreement (except for its own gross negligence or willful
misconduct) or (ii) be responsible in any manner to any of the Banks for any
recital, statement, representation or warranty made by the Company or any
Subsidiary of the Company or any officer thereof contained in this Agreement or
in any other Loan Document, or in any certificate, report, statement or other
document referred to or provided for in, or received by the Agent under or in
connection with, this Agreement or any other Loan Document, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
any other Loan Document, or for any failure of the Company or any other party
to any Loan Document to perform its obligations hereunder or thereunder.  No
Agent-Related Person shall be under any







                                       49
<PAGE>   54
obligation to any Bank to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or conditions of, this
Agreement or any other Loan Document, or to inspect the properties, books or
records of the Company or any of its Subsidiaries.

                 9.4  Reliance by Agent.

                 (a)      The Agent shall be entitled to rely, and shall be
fully protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, letter, telegram, telecopy, telex or telephone message,
statement or other document or conversation believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel (including counsel to the
Company), independent accountants and other experts selected by the Agent. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement or any other Loan Document unless it shall first receive such
advice or concurrence of the Requisite Banks as it deems appropriate and, if it
so requests, it shall first be indemnified to its satisfaction by the Banks
against any and all liability and expense which may be incurred by it by reason
of taking or continuing to take any such action.  The Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this
Agreement or any other Loan Document in accordance with a request or consent of
the Requisite Banks and such request and any action taken or failure to act
pursuant thereto shall be binding upon all of the Banks.

                 (b)      For purposes of determining compliance with the
conditions specified in Sections 4.1 and 4.2, each Bank shall be deemed to have
consented to, approved or accepted or to be satisfied with each document or
other matter required thereunder to be consented to or approved by or
acceptable or satisfactory to the Bank unless an officer of the Agent
responsible for the transactions contemplated by the Loan Documents shall have
received notice from the Bank prior to the initial Borrowing specifying its
objection thereto and either such objection shall not have been withdrawn by
notice to the Agent to that effect or the Bank shall not have made available to
the Agent the Bank's ratable portion of such Borrowing.

                 9.5  Notice of Default.  The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default,
except with respect to defaults in the payment of principal, interest and fees
payable to the Agent for the







                                       50
<PAGE>   55
account of the Banks, unless the Agent shall have received written notice from
a Bank or the Company referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a "notice of default".  In the
event that the Agent receives such a notice, the Agent shall give notice
thereof to the Banks.  The Agent shall take such action with respect to such
Default or Event of Default as shall be requested by the Requisite Banks;
provided, however, that unless and until the Agent shall have received any such
request, the Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Banks.

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

                 9.7  Indemnification.  The Banks agree to indemnify the
Agent-Related Persons (to the extent not reimbursed by or on behalf of the
Company and without limiting the obligation of the







                                       51
<PAGE>   56
Company to do so), ratably according to the respective amounts of their
outstanding Loans, or, if no Loans are outstanding, their Commitment, from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses and disbursements of any kind
whatsoever which may at any time (including at any time following the 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 or any document
contemplated by or referred to herein or therein or the transactions
contemplated hereby or thereby or any action taken or omitted by any such
person under or in connection with any of the foregoing; provided, however,
that no Bank shall be liable for the payment to the Agent-Related Persons of
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting solely
from such person's gross negligence or willful misconduct.  Without limitation
of the foregoing, each Bank shall reimburse the Agent promptly upon demand for
its ratable share of any costs or out-of-pocket expenses (including fees and
expenses of counsel and the allocated cost of in-house counsel) incurred by the
Agent in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Loan Document, or any
document contemplated by or referred to herein to the extent that the Agent is
not reimbursed for such expenses by or on behalf of the Company.

                 9.8  Agent in Individual Capacity.  Bank of America and its
Affiliates may make loans to, issue letters of credit for the account of,
accept deposits from and generally engage in any kind of business with the
Company and its Subsidiaries and Affiliates as though Bank of America were not
the Agent hereunder and without notice to the Banks.  With respect to its
Loans, Bank of America shall have the same rights and powers under this
Agreement as any other Bank and may exercise the same as though it were not the
Agent, and the terms "Bank" and "Banks" shall include Bank of America in its
individual capacity.

                 9.9  Successor Agent.  The Agent may, and at the request of
the Requisite Banks shall, resign as Agent upon 30 days' notice to the Banks.
If the Agent shall resign as Agent under this Agreement, the Requisite Banks
shall appoint from among the Banks a successor agent for the Banks which
successor agent shall be approved by the Company.  If no successor Agent is
appointed prior to the effective date of the resignation of the







                                       52
<PAGE>   57
Agent, the Agent may, but shall not be obligated to, appoint after consulting
with the Banks and the Company, a successor agent from among the Banks.  At end
of such 30 days' notice period any successor agent shall succeed to all the
rights, powers and duties of the retiring Agent and the term "Agent" shall mean
such successor agent and the retiring Agent's rights, powers and duties as
Agent shall be terminated.  After any retiring Agent's resignation hereunder as
Agent, the provisions of this Section 9 and Sections 10.4 and 10.5 shall inure
to its benefit as to any actions taken or omitted to be taken by it while it
was Agent under this Agreement.  Concurrently with giving a notice of

and no delay in exercising, on the part of the Agent, any Bank or the Company,

exercise of any other right, remedy, power or privilege.

                 10.4  Costs and Expenses.  The Company shall, whether or not

                                       54
<PAGE>   59
                 (b)      pay or reimburse each Bank and the Agent on demand
for all reasonable costs and expenses incurred by them in connection with the
enforcement or preservation of any rights (including in connection with any
"workout" or restructuring regarding the Loans) under this Agreement, any Loan
Document, and any such other documents, including reasonable fees and
out-of-pocket expenses of counsel (and the reasonable allocated cost of
internal counsel) to the Agent and to each of the Banks; and

                 (c)      pay or reimburse the Agent on demand for all
reasonable appraisal, audit, search and filing fees, incurred or sustained by
the Agent in connection with the matters referred to under paragraphs (a) and
(b) above.

                 10.5  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 each Bank.

                 10.6  Assignments, Participations etc.

                 (a)      Any Bank may, with the written consent of the Agent
and the Company, which consent shall not be unreasonably withheld, at any time
assign and delegate to one or more Eligible Assignees and, with notice to the
Agent, but without the consent of the Agent, may assign to any of its
wholly-owned bank Affiliates (each an "Assignee") all or any part of the Loans
or the Commitment or any other rights or obligations of such Bank hereunder in
a minimum amount equal to the lesser of (i) such Bank's Commitment and (ii)
$10,000,000; provided, however, that the Commitment of any Bank after giving
effect to any assignment shall not be less than $10,000,000; provided, further,
that the Company and the Agent may continue to deal solely and directly with
such Bank in connection with the interests so assigned to an Assignee until (i)
written notice of such assignment, together with payment instructions,
addresses and related information with respect to the Assignee, shall have been
given to the Company and the Agent by such Bank and the Assignee and (ii) such
Bank and its Assignee shall have delivered to the Company and the Agent a
Notice of Commitment Assignment Notice and Acceptance substantially in the form
of Exhibit C ("Notice of Assignment and Acceptance"); and (iii) the processing
fees of $5,000 shall have







                                       55
<PAGE>   60
been paid to the Agent.  Any Bank may at any time assign all or any portion of
its rights under this Agreement to a Federal Reserve Bank.  No such assignment
shall release the transferor Bank from its obligations hereunder.

                 (b)      From and after the date that the Agent notifies the
assignor Bank and the Assignee that it has received the Notice of Assignment
and Acceptance, (i) the Assignee thereunder shall be a party hereto and, to the
extent that rights and obligations hereunder have been assigned to it pursuant
to such Notice of Assignment and Acceptance, shall have the rights and
obligations of a Bank under the Loan Documents and (ii) the assignor Bank
shall, to the extent that rights and obligations hereunder have been assigned
by it pursuant to such Notice of Assignment and Acceptance, relinquish its
rights and be released from its obligations under the Loan Documents.  The
Commitment allocated to each Assignee shall reduce the Commitment of the
assigning Bank pro tanto.

                 (c)      Any Bank may at any time sell to one or more banks or
other entities (a "Participant"), participating interests in any Loans, the
Commitment of that Bank or any other interest of that Bank hereunder; provided,
however, that (i) the Bank's obligations under this Agreement shall remain
unchanged, (ii) the Bank shall remain solely responsible for the performance of
such obligations, (iii) the Company and the Agent shall continue to deal solely
and directly with the Bank in connection with the Bank's rights and obligations
under this Agreement, and (iv) no Bank shall transfer or grant any
participating interest under which the Participant shall have rights to approve
any amendment to, or any consent or waiver with respect to this Agreement
except to the extent such amendment, consent or waiver would require unanimous
consent as described in the first proviso to Section 10.1. In the case of any
such participation, the Participant shall not have any rights under this
Agreement, or any of the other Loan Documents, and all amounts payable by the
Company hereunder shall be determined as if such 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 a Bank under this
Agreement.







                                       56
<PAGE>   61
                 (d)      Each Bank agrees to take normal and reasonable
precautions and exercise due care to maintain the confidentiality of all
non-public information provided to it by the Company or any Subsidiary of the
Company or by the Agent on such Company's or Subsidiary's behalf in connection
with this Agreement and neither it nor any of its Affiliates shall use any such
information for any purpose or in any manner other than pursuant to the terms
contemplated by this Agreement, except to the extent such information (i) was
or becomes generally available to the public other than as a result of a
disclosure by the Bank, or (ii) was or becomes available on a non-confidential
basis from a source other than the Company, provided that such source is not
bound by a confidentiality agreement with the Company known to the Bank;
provided, further, however, that any Bank may disclose such information (A) at
the request of any Bank regulatory authority or in connection with an
examination of such Bank by any such authority; (B) pursuant to subpoena or
other court process; (C) when required to do so in accordance with the
provisions of any applicable law; (D) at the express direction of any other
agency of any State of the United States of America or of any other
jurisdiction in which such Bank conducts its business; and (E) to such Bank's
independent auditors and other professional advisors who have agreed to keep
such information confidential.  Notwithstanding the foregoing, the Company
authorizes each Bank to disclose to any Participant or Assignee (each, a
"Transferee") and any prospective Transferee such financial and other
information in such Bank's possession concerning the Company or its
Subsidiaries which has been delivered to the Banks pursuant to this Agreement
or which has been delivered to the Banks by the Company in connection with the
Banks' credit evaluation of the Company prior to entering into this Agreement;
provided that such Transferee agrees in writing to such Bank to keep such
information confidential to the same extent required of the Banks hereunder.

                 10.7  Set-off.  In addition to any rights and remedies of the
Banks provided by law, if an Event of Default exists, each Bank is authorized
at any time and from time to time, without prior notice to the Company, any
such notice being waived by the Company to the fullest extent permitted by law,
to set-off and apply any and all deposits (general or special, time or demand,
provisional or final) at any time held and other indebtedness at any time owing
by such Bank to or for the credit or the account of the Company against any and
all obligations of the Company now or hereafter existing under this Agreement
or any other Loan Document and any Loan held by such Bank irrespective of
whether or not the Agent or such Bank shall have made demand under this
Agreement or any Loan Document and although such obligations may







                                       57
<PAGE>   62
be contingent or unmatured.  Each Bank agrees promptly to notify the Company
and the Agent after any such set-off and application made by such Bank;
provided, however, that the failure to give such notice shall not affect the
validity of such set-off and application.  The rights of each Bank under this
Section 10.7 are in addition to the other rights and remedies (including
without limitation, other rights of set-off) which the Bank may have.

                 10.8  Sharing of Payments, Etc.  If, other than as provided in
Section 3.1, 3.5 or 3.6, any Bank shall obtain on account of the Loans made by
it any payment (whether voluntary, involuntary, through the exercise of any
right of set-off, or otherwise) (a) in excess of its Pro Rata Share of payments
on account of the Loans obtained by all the Banks, such Bank shall forthwith
(i) notify the Agent of such fact (and the Agent will promptly notify the other
Banks), and (ii) purchase from the other Banks such participations in the Loans
made by them as shall be necessary to cause such purchasing Bank to share the
excess payment ratably with each of them; provided, however, that if all or any
portion of such excess payment is thereafter recovered from the purchasing
Bank, such purchase shall to that extent be rescinded and each other Bank shall
repay to the purchasing Bank the purchase price paid thereto together with an
amount equal to such paying Bank's ratable share (according to the proportion
of (A) the amount of such paying Bank's required repayment to (B) the total
amount so recovered from the purchasing Bank) of any interest or other amount
paid or payable by the purchasing Bank in respect of the total amount so
recovered.  The Company agrees that any Bank so purchasing a participation from
another Bank pursuant to this Section 10.8 may, to the fullest extent permitted
by law, exercise all its rights of payment (including the right of set-off, but
subject to Section 10.7) with respect to such participation as fully as if such
Bank were the direct creditor of the Company in the amount of such
participation.  The Agent shall keep records (which shall be conclusive and
binding in the absence of manifest error), of participations purchased pursuant
to this Section 10.8 and shall in each case notify the Banks following any such
purchases.

                 10.9  Indemnity.  Whether or not the transactions contemplated
hereby shall be consummated:

                 (a)      General Indemnity.  The Company shall pay, indemnify,
and hold each Bank, the Agent and each of their respective officers, directors,
employees, counsel, agents and attorneys-in-fact (each, an "Indemnified
Person") harmless from and against any and all liabilities, obligations,
losses,







                                       58
<PAGE>   63
damages, penalties, actions, judgments, suits, costs, charges, expenses or
disbursements (including Attorney Costs) of any kind or nature whatsoever in
connection with or arising out of or as a result of this Agreement or any other
Loan Document or the Borrower's use of any Loan, or any investigation,
litigation or proceeding related thereto, whether or not the Agent or such
Lender 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 arising from the
gross negligence or willful misconduct of such Indemnified Person.

                 (b)      Survival; Defense.  The obligations in this Section
10.9 shall survive payment of all other Obligations.  At the election of any
Indemnified Person, the Company shall defend such Indemnified Person using
legal counsel reasonably satisfactory to such Indemnified Person in such
Person's sole discretion, at the sole cost and expense of the Company, and the
Banks and the Agent shall cooperate with the reasonable requests of such
counsel.  All amounts owing under this Section 10.9 shall be paid within 30
days after demand.

                 10.10  Marshalling; Payments Set Aside.  Neither the Agent nor
the Banks shall be under any obligation to marshall any assets in favor of the
Company or any other Person or against or in payment of any or all of the
Obligations.  To the extent that the Company makes a payment or payments to the
Agent or the Banks, or the Agent or the Banks enforce their Liens or exercise
their rights of set-off, and such payment or payments or the proceeds of such
enforcement or set-off or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside or required 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
enforcement or set- off had not occurred.

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

                 10.12  Counterparts.  This Agreement may be executed by one or
more of the parties to this Agreement in any number of separate counterparts,
each of which, when so executed, shall be deemed an original, and all of said
counterparts taken together shall be deemed to constitute but one and the same
instrument. A set of the copies of this Agreement signed by all the parties
shall be lodged with the Company and the Agent.

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

                 10.14  Governing Law and Jurisdiction.

                 (a)      THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF CALIFORNIA.

                 (b)      ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS
AGREEMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF CALIFORNIA OR OF THE
UNITED STATES FOR THE CENTRAL DISTRICT OF CALIFORNIA, AND BY EXECUTION AND
DELIVERY OF THIS AGREEMENT, EACH OF THE COMPANY, THE AGENT AND THE BANKS
CONSENTS, FOR ITSELF AND IN RESPECT OF ITS PROPERTY, TO THE JURISDICTION OF
THOSE COURTS.  EACH OF THE COMPANY, THE AGENT AND THE BANKS IRREVOCABLY WAIVES
ANY OBJECTION, INCLUDING ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE
GROUNDS OF FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE
BRINGING OF ANY ACTION OR PROCEEDING IN SUCH JURISDICTION IN RESPECT OF THIS
AGREEMENT OR ANY DOCUMENT RELATED HERETO.  THE COMPANY, THE AGENT AND THE BANKS
EACH WAIVE PERSONAL SERVICE OF ANY SUMMONS, COMPLAINT OR OTHER PROCESS, WHICH
MAY BE MADE BY ANY OTHER MEANS PERMITTED BY CALIFORNIA LAW.

                 10.15  Waiver of Jury Trial.  THE COMPANY, THE BANKS AND THE
AGENT EACH WAIVE THEIR RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR
CAUSE OF ACTION BASED UPON OR ARISING OUT OF OR RELATED TO THIS AGREEMENT, THE
OTHER LOAN DOCUMENTS, OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY, IN
ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY OF THE
PARTIES AGAINST ANY OTHER PARTY OR PARTIES, WHETHER WITH RESPECT TO CONTRACT
CLAIMS, TORT CLAIMS, OR OTHERWISE.  THE COMPANY, THE BANKS AND THE AGENT EACH
AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL
WITHOUT A JURY.  WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT
THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF







                                       60
<PAGE>   65
THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN
WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS AGREEMENT
OR THE OTHER LOAN DOCUMENTS OR ANY PROVISION HEREOF OR THEREOF.  THIS WAIVER
SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR
MODIFICATIONS TO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

                 10.16  Purchasing and Selling of Commitments and Loans.  On
the date of this Agreement, certain Banks (the "Buying Banks") hereby agree to
purchase without recourse, and certain Banks (the "Selling Banks") hereby agree
to sell without recourse, such an interest (with respect to the Prior
Agreement) in the Aggregate Commitment and the outstanding Loans (under the
Prior Agreement) as is required (together with the increase in the Aggregate
Commitment provided for in Schedule 1.1) to give each Bank its share of the
Aggregate Commitment and Loans in this Agreement indicated on Schedule 1.1
hereto.

                 Each Selling Bank represents and warrants to each Buying Bank
that it is the legal and beneficial owner of the Commitment and Loans being
assigned by it and that the same are free and clear of any adverse claim.
Other than as provided above, no Selling Bank makes any representation or
warranty and assumes no responsibility with respect to the Commitments, the
Loans, this Agreement or any other instrument or document furnished pursuant
thereto, the financial condition of the Company, or the performance or
observance by the Company hereunder.  The Company agrees to pay on demand
directly to any Selling Bank any costs of the type set forth in Section 3.6 of
the Agreement incurred by such Selling Bank in respect of any portion of its
Loans being assigned hereunder.  The Company and the Agent hereby consent to
such assignments.

                 By signing below, each Buying Bank not heretofore a Bank under
the Prior Agreement agrees to be a party to, and be bound by the terms of, this
Agreement as a "Bank" hereunder.  From and after the date hereof, and upon
repayment to them of all principal and interest due to them in connection with
the Prior Agreement, Mellon Bank, N.A., PNC Bank, National Association and
American National Bank & Trust Company of Shawnee (which were parties to the
Prior Agreement) shall have no Commitments under this Agreement and shall no
longer be parties to this Agreement.

                 10.17  Entire Agreement.  This Agreement, together with the
other Loan Documents, embodies the entire Agreement and understanding among the
Company, the Banks and the Agent and supersedes all prior or contemporaneous
Agreements and







                                       61
<PAGE>   66
understandings of such persons, verbal or written, relating to the subject
matter hereof and thereof except for the fee letters referred to in Section
2.10 and any prior arrangements made with respect to the payment by the Company
of (or any indemnification for) any fees, costs or expenses payable to or
incurred (or to be incurred) by or on behalf of the Agent or the Banks.

                 10.18  Interpretation.  This Agreement is the result of
negotiations between and has been reviewed by counsel to the Agent, the Company
and other parties, and is the product of all parties hereto.  Accordingly, this
Agreement and the other Loan Documents shall not be construed against the
Banks, the Agent or the Company merely because of the Agent's, the Banks' or
the Company's involvement in the preparation of such documents and agreements.

                 IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed and delivered by their proper and duly authorized
officers as of the day and year first above written.
