                  (A) VOLUNTARY TERMINATION. During the Agreement Term, the

                  (B) TERMINATION FOR CAUSE. During the Agreement Term, the
         Employee's employment may be terminated by the Company for Cause (as

         clauses (i), (ii), and (iv) of the definition of Cause and, with
         respect to clauses (iii), (v),(vi) and (vii) of the definition of

<PAGE>   4

         Cause, shall be effective on the date of the expiration of the cure
         period if the Employee fails to cure the breach within the cure period.
         Upon such termination for Cause, the Employee shall not be entitled to
         any further compensation or rights under this Agreement other than his
         Accrued Rights.

                  For purposes of this Agreement, "Cause" shall mean misconduct,
         including: (i) a conviction of any felony or any crime involving moral
         turpitude or dishonesty; (ii) participation in a fraud or act of
         dishonesty against the Company or any of its subsidiaries or Affiliates
         or the willful fabrication of records of the Company or any of its
         subsidiaries or Affiliates; (iii) a material breach of the Company's
         policies after being provided with notice of such failure and an
         opportunity to cure within seven (7) days of receipt of such notice;
         (iv) any other act or omission or series of acts or omissions which are
         injurious to the financial condition or business reputation of the
         Company or any of its subsidiaries or Affiliates; (v) a breach of this
         Agreement after being provided with written notice of such breach and
         an opportunity to cure within seven (7) days of receipt of such notice;
         (vi) a failure or refusal in a material respect of the Employee to
         follow the reasonable policies or directions of the Company as
         specified by the Board or the Employee's supervisor after being
         provided with written notice of such failure and an opportunity to cure
         within seven (7) days of receipt of such notice; or (vii) a failure to
         carry out the duties of the Employee's position as a result of drug
         abuse or alcoholism or other form of substance abuse, in each case
         after being provided with notice of such failure and an opportunity to
         cure within seven (7) days of receipt of such notice. Disability shall
         not constitute "Cause."

                  (C) TERMINATION WITHOUT CAUSE. During the Agreement Term, the
         Company may terminate the employment of the Employee at any time for
         any reason other than Cause upon thirty (30) days' prior written notice
         to the Employee. Upon such termination without Cause, the Employee will
         receive: (i) his Accrued Rights, (ii) an amount equal to six (6) months
         of base salary, less payroll deductions and required withholdings,
         payable in equal weekly installments, (iii) a lump sum payment of that
         portion of the bonus the Employee is entitled to for the calendar year
         in which the termination occurs pro-rated based upon the number of full
         months the Employee was employed in such year, (iv) continuation of all
         Company Benefits for a period of six (6) months and (v) immediate
         vesting of all Employee's unvested stock options covered by the
         Assignment.

                  (D) DISABILITY. During the Agreement Term, the Company may
         terminate the employment of the Employee on account of a Disability (as
         defined below) upon thirty (30) days' prior written notice to the
         Employee. Upon such termination on account of a Disability, the
         Employee will receive: (i) his Accrued Rights, (ii) a lump sum payment
         equal to one(1) year of base salary, less payroll deductions and
         required withholdings, (iii) a lump sum payment of that portion of the

                                       4
<PAGE>   5

         bonus the Employee is entitled to for the calendar year pro-rated based
         upon the number of full months the Employee was employed in such year,
         and (iv) continuation of all Company Benefits for a period of four (4)
         months.

                  For purposes of this Agreement, "Disability" shall mean a
         disability which prevents the Employee from substantially performing
         his duties under this Agreement for a period of at least 90 consecutive
         days or 120 non-consecutive days within any 365-day period. Any
         question as to the existence of a Disability of the Employee as to
         which the Employee and the Company cannot agree shall be determined in
         writing by a qualified independent physician mutually acceptable to the
         Employee and the Company. If the Employee and the Company cannot agree
         as to a qualified independent physician, each shall appoint such a
         physician and those two physicians shall select a third who shall make
         such determination in writing. The determination of a Disability made
         in writing to the Company and the Employee shall be final and
         conclusive for all purposes of this Agreement.

                  (E) DEATH. In the event of the death of the Employee during
         the Agreement Term, this Agreement shall automatically terminate
         (subject to Section 7.9), such termination to be effective on the date
         of the Employee's death, and the Company shall pay to the Employee or
         his heirs, executors or administrators (i) his Accrued Rights and (ii)
         a portion of a discretionary bonus, if any, which may otherwise have
         been paid to the Employee pursuant to Section 2.2 hereof with respect
         to the annual period in which the death occurs pro-rated based upon the
         number of full months the Employee was employed in such annual period
         prior to his death.

6. CONTINUATION OF EMPLOYMENT/RESTRICTIVE COVENANT. The Employee acknowledges
and recognizes the highly competitive nature of the businesses of the Company
and its Affiliates and accordingly agrees that during the term of the Employee's

supplier's business with the Company or any Affiliate of the Company, or its or
their successors; (c) directly or indirectly employ, or knowingly permit any
company or business directly or indirectly controlled by him, to employ, any
person who was employed by the Company or any Affiliate of the Company at or
within the six (6) month period immediately preceding the date of such

employment, or in any manner seek to induce any such person to leave his or her
employment; or (d) at any time following the date hereof, directly or
indirectly, in any way utilize, disclose, copy, reproduce or retain in his/her
possession the Company's or any of the Company Affiliates' proprietary rights or
records, including, but not limited to, any of its or their customer lists. As

months of such termination.

         The Employee agrees and acknowledges that the restrictions contained in
this Section 6 are reasonable in scope and duration and are necessary to protect
the Company after the date hereof. If any provision of this Section 6 as applied
to any party or to any circumstance is adjudged by a court to be invalid or
unenforceable, the same will in no way affect any other circumstance or the
validity or enforceability of this Agreement. If any such provision, or any part
thereof, is held to be unenforceable because of the duration of such provision
or the area covered thereby, the parties agree that the court making such
determination shall have the power to reduce the duration and/or area of such
provision, and/or to delete specific words or phrases, and in its reduced form,
such provision shall then be enforceable and shall be enforced. The parties
agree and acknowledge that the breach of this Section 6 will cause irreparable
damage to the Company and upon breach of any provision of this Section 6, the
Company shall be entitled to injunctive relief, specific performance or other
equitable relief; provided, however, that this shall in no way limit any other
remedies which the Company may have (including, without limitation, the right to
seek monetary damages).

         agreements (including this Agreement) and other contractual instruments
         shall be deemed to include all subsequent amendments and other
         modifications thereto, but only to the extent such amendments and other
         modifications are not prohibited by the terms of any Loan Document, and
         (ii) references to any statute or regulation are to be construed as
         including all statutory and regulatory provisions consolidating,
         amending, replacing, supplementing or interpreting such statute or
         regulation.

         (d) This Agreement and the other Loan Documents may use several
         different limitations, tests or measurements to regulate the same or
         similar matters. All such limitations, tests and measurements are
         cumulative and shall each be performed in accordance with their terms.

         (e) This Agreement and the other Loan Documents are the result of
         negotiations among and have been reviewed by counsel to the
         Administrative Agent, the Company, the Banks and the other parties
         thereto and are the products of all parties. Accordingly, they shall
         not be construed against the Administrative Agent or the Banks merely
         because of the Administrative Agent's or Banks' involvement in their
         preparation.

2.1.1 REVOLVING LOANS. Each Bank will make loans on a revolving basis
("REVOLVING LOANS") from time to time before the Revolving Termination Date in
such Bank's Revolving Percentage of such aggregate amounts as the Company may
from time to time request from all Banks; PROVIDED that the Revolving
Outstandings shall not at any time exceed the lesser of (a) the Revolving
Commitment Amount or (b) the Borrowing Base. Amounts borrowed under this SECTION
2.1.1 may be borrowed, repaid and reborrowed until the Revolving Termination
Date.

2.1.2 L/C COMMITMENT. (a) The Issuing Banks will issue standby letters of
credit, in each case containing such terms and conditions as are permitted by
this Agreement and are reasonably satisfactory to the applicable Issuing Bank

                                       20
<PAGE>   28

and the Company (each a "LETTER OF CREDIT"), at the request of and for the
account of the Company (or jointly for the account of the Company and any
Subsidiary) from time to time before the date which is 30 days prior to the
scheduled Revolving Termination Date and (b) as more fully set forth in SECTION
2.3.2, each Bank agrees to purchase a participation in each such Letter of
Credit; PROVIDED that (i) the aggregate Stated Amount of all Letters of Credit
shall not at any time exceed $5,000,000 and (ii) the Revolving Outstandings
shall not at any time exceed the lesser of (a) the Revolving Commitment Amount
or (b) the Borrowing Base.

2.1.3 TERM LOANS. Each Bank will make a single term loan ("each a TERM LOAN") on
the Effective Date in such Bank's Term Percentage of $30,000,000. Amounts repaid
with respect to Term Loans may not be reborrowed.

2.2 LOAN PROCEDURES.

2.2.1 VARIOUS TYPES OF LOANS. Each Revolving Loan and Term Loan shall be either
a Base Rate Loan or a Eurodollar Loan (each a "TYPE" of Loan), as the Company
shall specify in the related notice of borrowing or conversion pursuant to
SECTION 2.2.2 or 2.2.3. Eurodollar Loans having the same Interest Period are
sometimes called a "GROUP" or collectively "Groups". Base Rate Loans and
Eurodollar Loans may be outstanding at the same time, PROVIDED that (i) not more
than ten different Groups of Eurodollar Loans shall be outstanding at any one
time, and (ii) the aggregate principal amount of each Group of Eurodollar Loans
shall at all times be at least $1,000,000 and an integral multiple of $500,000.
All borrowings, conversions and repayments of Loans shall be effected so that
each Bank will have a pro rata share (according to its Percentage) of all types
and Groups of Loans.

2.2.2 BORROWING PROCEDURES. The Company shall give written notice or telephonic
notice (followed promptly by written confirmation thereof) to the Administrative
Agent of each proposed borrowing not later than (a) in the case of a Base Rate
borrowing, 10:00 A.M., Chicago time, on the proposed date of such borrowing, and
(b) in the case of a Eurodollar borrowing, 10:00 A.M., Chicago time, at least
three Business Days prior to the proposed date of such borrowing. Each such
notice shall be effective upon receipt by the Administrative Agent, shall be
irrevocable, and shall specify the date, amount and type of borrowing and, in
the case of a Eurodollar borrowing, the initial Interest Period therefor.
Promptly upon receipt of such notice, the Administrative Agent shall advise each
Bank thereof. Not later than 1:00 p.m., Chicago time, on the date of a proposed
borrowing, each Bank shall provide the Administrative Agent at the office
specified by the Administrative Agent with immediately available funds covering
such Bank's Percentage of such borrowing and, so long as the Administrative
Agent has not received written notice that the conditions precedent set forth in
SECTION 11 with respect to such borrowing have not been satisfied, the
Administrative Agent shall pay over the requested amount to the Company on the
requested borrowing date. Each borrowing shall be on a Business Day. Each
borrowing shall be in an aggregate amount of at least $1,000,000 and an integral
multiple of $500,000.

2.2.3 CONVERSION AND CONTINUATION PROCEDURES. (a) Subject to the provisions of
SECTION 2.2.1, the Company may, upon irrevocable written notice to the
Administrative Agent in accordance with CLAUSE (B) below:

                  (i) elect, as of any Business Day, to convert any outstanding
         Loan into a Loan of a different type; or

                                       21
<PAGE>   29

                           (ii) elect, as of the last day of the applicable
                  Interest Period, to continue any Group of Eurodollar Loans
                  having an Interest Period expiring on such day (or any part
                  thereof in an aggregate amount not less t han $1,000,000 or a
                  higher integral multiple of $500,000) for a new Interest
                  Period.

                  (b) The Company shall give written or telephonic (followed
         promptly by written confirmation thereof) notice to the Administrative
         Agent of each proposed conversion or continuation not later than (i) in
         the case of conversion into Base Rate Loans, 10:00 a.m., Chicago time,
         on the proposed date of such conversion; and (ii) in the case of a
         conversion into or continuation of Eurodollar Loans, 10:00 a.m.,
         Chicago time, at least three Business Days prior to the proposed date
         of such conversion or continuation, specifying in each case:

                           (1) the proposed date of conversion or continuation;

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

                           (3) the type of Loans resulting from the proposed
                  conversion or continuation; and

                           (4) in the case of conversion into, or continuation
                  of, Eurodollar Loans, the duration of the requested Interest
                  Period therefor.

                  (c) If upon expiration of any Interest Period applicable to
         any Eurodollar Loan, the Company has failed to select timely a new
         Interest Period to be applicable to such Eurodollar Loan, the Company
         shall be deemed to have elected to convert such Eurodollar Loan into a
         Base Rate Loan effective on the last day of such Interest Period.

                  (d) The Administrative Agent will promptly notify each Bank of
         its receipt of a notice of conversion or continuation pursuant to this
         SECTION 2.2 or, if no timely notice is provided by the Company, of the
         details of any automatic conversion.

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

2.3 LETTER OF CREDIT PROCEDURES.

2.3.1 L/C APPLICATIONS. The Company shall give notice to the Administrative
Agent and the applicable Issuing Bank of the proposed issuance of each Letter of
Credit on a Business Day which is at least three Business Days (or such lesser
number of days as the Administrative Agent and such Issuing Bank shall agree in
any particular instance) prior to the proposed date of issuance of such Letter
of Credit. Each such notice shall be accompanied by an L/C Application, duly
executed by the Company (together with any Subsidiary for the account of which
the related Letter of Credit is to be issued) and in all respects satisfactory
to the Administrative Agent and the applicable Issuing Bank, together with such
other documentation as the Administrative Agent or such Issuing Bank may
reasonably request in support thereof, it being understood that each L/C

                                       22
<PAGE>   30

Application shall specify, among other things, the date on which the proposed
Letter of Credit is to be issued, the expiration date of such Letter of Credit
(which shall not be later than seven days prior to the Revolving Termination
Date) and whether such Letter of Credit is to be transferable in whole or in
part. So long as the applicable Issuing Bank has not received written notice
that the conditions precedent set forth in SECTION 11 with respect to the
issuance of such Letter of Credit have not been satisfied, such Issuing Bank
shall issue such Letter of Credit on the requested issuance date. Each Issuing
Bank shall promptly advise the Administrative Agent of the issuance of each
Letter of Credit by such Issuing Bank and of any amendment thereto, extension
thereof or event or circumstance changing the amount available for drawing
thereunder.

2.3.2 PARTICIPATIONS IN LETTERS OF CREDIT. Concurrently with the issuance of
each Letter of Credit, the applicable Issuing Bank shall be deemed to have sold
and transferred to each other Bank, and each other Bank shall be deemed
irrevocably and unconditionally to have purchased and received from such Issuing
Bank, without recourse or warranty, an undivided interest and participation, to
the extent of such other Bank's Revolving Percentage, in such Letter of Credit
and the Company's reimbursement obligations with respect thereto. For the
purposes of this Agreement, the unparticipated portion of each Letter of Credit
shall be deemed to be the applicable Issuing Bank's "participation" therein.
Each Issuing Bank hereby agrees, upon request of the Administrative Agent or any
Bank, to deliver to such Bank a list of all outstanding Letters of Credit issued
by such Issuing Bank, together with such information related thereto as such
Bank may reasonably request.

2.3.3 REIMBURSEMENT OBLIGATIONS. The Company hereby unconditionally and
irrevocably agrees to reimburse the applicable Issuing Bank for each payment or
disbursement made by such Issuing Bank under any Letter of Credit honoring any
demand for payment made by the beneficiary thereunder, in each case on the date
that such payment or disbursement is made. Any amount not reimbursed on the date
of such payment or disbursement shall bear interest from the date of such
payment or disbursement to the date that such Issuing Bank is reimbursed by the
Company therefor, payable on demand, at a rate per annum equal to the Base Rate
from time to time in effect PLUS the Base Rate Margin from time to time in
effect PLUS, beginning on the third Business Day after receipt of notice from
the Issuing Bank of such payment or disbursement, 2%. The applicable Issuing
Bank shall notify the Company and the Administrative Agent whenever any demand
for payment is made under any Letter of Credit by the beneficiary thereunder;
PROVIDED that the failure of such Issuing Bank to so notify the Company shall
not affect the rights of such Issuing Bank or the Banks in any manner
whatsoever.

2.3.4 LIMITATION ON OBLIGATIONS OF ISSUING BANKS. In determining whether to pay
under any Letter of Credit, no Issuing Bank shall have any obligation to the
Company or any Bank other than to confirm that any documents required to be
delivered under such Letter of Credit appear to have been delivered and appear
to comply on their face with the requirements of such Letter of Credit. Any
action taken or omitted to be taken by an Issuing Bank under or in connection

                                       23
<PAGE>   31

with any Letter of Credit, if taken or omitted in the absence of gross
negligence and willful misconduct, shall not impose upon such Issuing Bank any
liability to the Company or any Bank and shall not reduce or impair the
Company's reimbursement obligations set forth in SECTION 2.3.3 or the
obligations of the Banks pursuant to SECTION 2.3.5.

2.3.5 FUNDING BY BANKS TO ISSUING BANKS. If an Issuing Bank makes any payment or
disbursement under any Letter of Credit and the Company has not reimbursed such
Issuing Bank in full for such payment or disbursement by 10:00 A.M., Chicago
time, on the date of such payment or disbursement, or if any reimbursement
received by such Issuing Bank from the Company is or must be returned or
rescinded upon or during any bankruptcy or reorganization of the Company or
otherwise, each other Bank shall be obligated to pay to the Administrative Agent
for the account of such Issuing Bank, in full or partial payment of the purchase
price of its participation in such Letter of Credit, its pro rata share
(according to its Revolving Percentage) of such payment or disbursement (but no
such payment shall diminish the obligations of the Company under SECTION 2.3.3),
and upon notice from the applicable Issuing Bank, the Administrative Agent shall
promptly notify each other Bank thereof. Each other Bank irrevocably and
unconditionally agrees to so pay to the Administrative Agent in immediately
available funds for the applicable Issuing Bank's account the amount of such
other Bank's Revolving Percentage of such payment or disbursement. If and to the
extent any Bank shall not have made such amount available to the Administrative
Agent by 2:00 P.M., Chicago time, on the Business Day on which such Bank
receives notice from the Administrative Agent of such payment or disbursement
(it being understood that any such notice received after noon, Chicago time, on
any Business Day shall be deemed to have been received on the next following
Business Day), such Bank agrees to pay interest on such amount to the
Administrative Agent for the applicable Issuing Bank's account forthwith on
demand for each day from the date such amount was to have been delivered to the
Administrative Agent to the date such amount is paid, at a rate per annum equal
to (a) for the first three days after demand, the Federal Funds Rate from time
to time in effect and (b) thereafter, the Base Rate from time to time in effect.
Any Bank's failure to make available to the Administrative Agent its Revolving
Percentage of any such payment or disbursement shall not relieve any other Bank
of its obligation hereunder to make available to the Administrative Agent such
other Bank's Revolving Percentage of such payment, but no Bank shall be
responsible for the failure of any other Bank to make available to the
Administrative Agent such other Bank's Revolving Percentage of any such payment
or disbursement.

2.4 SWING LINE LOANS.

2.4.1 SWING LINE LOANS. Subject to the terms and conditions of this Agreement,
the Swing Line Bank may from time to time, in its discretion, make loans to the
Company (collectively the "SWING LINE LOANS" and individually each a "SWING LINE
LOAN") in accordance with this SECTION 2.4 in an aggregate amount not at any
time exceeding $2,500,000; PROVIDED that this amount shall increase to
$5,000,000 at the time that the Swing Line Bank's Revolving Commitment is at
least $5,000,000; PROVIDED FURTHER that the Revolving Outstandings shall not at
any time exceed the lesser of (a) the Revolving Commitment Amount or (b) the
Borrowing Base. Amounts borrowed under this SECTION 2.4 may be borrowed, repaid
and (subject to the agreement of the Swing Line Bank) reborrowed until the
Revolving Termination Date.

2.4.2 SWING LINE LOAN PROCEDURES. The Company shall give written or telephonic
notice to the Administrative Agent (which shall promptly inform the Swing Line
Bank) of each proposed Swing Line Loan not later than 12:00 noon, Chicago time,
on the proposed date of such Swing Line Loan. Each such notice shall be

                                       24
<PAGE>   32

effective upon receipt by the Administrative Agent and shall specify the date
and amount of such Swing Line Loan, which shall be not less than $100,000 or a
higher integral multiple thereof. So long as the Swing Line Bank has not
received written notice that the conditions precedent set forth in SECTION 11
with respect to the making of such Swing Line Loan have not been satisfied, the
Swing Line Bank may make the requested Swing Line Loan. If the Swing Line Bank
agrees to make the requested Swing Line Loan, the Swing Line Bank shall pay over
the requested amount to the Company on the requested borrowing date.
Concurrently with the making of any Swing Line Loan, the Swing Line Bank shall
be deemed to have sold and transferred, and each other Bank shall be deemed to
have purchased and received from the Swing Line Bank, an undivided interest and
participation to the extent of such other Bank's Revolving Percentage in such
Swing Line Loan (but such participation shall remain unfunded until required to
be funded pursuant to SECTION 2.4.3).

2.4.3 REFUNDING OF, OR FUNDING OF PARTICIPATIONS IN, SWING LINE LOANS. The Swing
Line Bank may at any time, in its sole discretion, on behalf of the Company
(which hereby irrevocably authorizes the Swing Line Bank to act on its behalf)
deliver a notice to the Administrative Agent requesting that each Bank
(including the Swing Line Bank in its individual capacity) make a Revolving Loan
(which shall be a Base Rate Loan) in such Bank's Revolving Percentage of the
aggregate amount of Swing Line Loans outstanding on such date for the purpose of
repaying all Swing Line Loans (and, upon receipt of the proceeds of such
Revolving Loans, the Administrative Agent shall apply such proceeds to repay
Swing Line Loans); PROVIDED that if the conditions precedent to a borrowing of
Revolving Loans are not then satisfied or for any other reason the Banks may not
then make Revolving Loans, then instead of making Revolving Loans each Bank
(other than the Swing Line Bank) shall become immediately obligated to fund its
participation in all outstanding Swing Line Loans and shall pay to the
Administrative Agent for the account of the Swing Line Bank an amount equal to
such Bank's Revolving Percentage of such Swing Line Loans. If and to the extent
any Bank shall not have made such amount available to the Administrative Agent
by 2:00 P.M., Chicago time, on the Business Day on which such Bank receives
notice from the Administrative Agent of its obligation to fund its participation
in Swing Line Loans (it being understood that any such notice received after
12:00 noon, Chicago time, on any Business Day shall be deemed to have been
received on the next following Business Day), such Bank agrees to pay interest
on such amount to the Administrative Agent for the Swing Line Bank's account
forthwith on demand for each day from the date such amount was to have been
delivered to the Administrative Agent to the date such amount is paid, at a rate
per annum equal to (a) for the first three days after demand, the Federal Funds
Rate from time to time in effect and (b) thereafter, the Base Rate from time to
time in effect. Any Bank's failure to make available to the Administrative Agent
its Revolving Percentage of the amount of all outstanding Swing Line Loans shall
not relieve any other Bank of its obligation hereunder to make available to the
Administrative Agent such other Bank's Revolving Percentage of such amount, but
no Bank shall be responsible for the failure of any other Bank to make available
to the Administrative Agent such other Bank's Revolving Percentage of any such
amount.

2.4.4 REPAYMENT OF PARTICIPATIONS. Upon (and only upon) receipt by the
Administrative Agent for the account of the Swing Line Bank of immediately
available funds from or on behalf of the Company (a) in reimbursement of any

                                       25
<PAGE>   33

Swing Line Loan with respect to which a Bank has paid the Administrative Agent
for the account of the Swing Line Bank the amount of such Bank's participation
therein or (b) in payment of any interest on a Swing Line Loan, the
Administrative Agent will pay to such Bank its pro rata share (according to its
Revolving Percentage) thereof (and the Swing Line Bank shall receive the amount
otherwise payable to any Bank which did not so pay the Administrative Agent the
amount of such Bank's participation in such Swing Line Loan).

2.4.5 PARTICIPATION OBLIGATIONS UNCONDITIONAL. (a) Each Bank's obligation to
make available to the Administrative Agent for the account of the Swing Line
Bank the amount of its participation interest in all Swing Line Loans as
provided in SECTION 2.4.3 shall be absolute and unconditional and shall not be
affected by any circumstance, including (i) any set-off, counterclaim,
recoupment, defense or other right which such Bank may have against the Swing
Line Bank or any other Person, (ii) the occurrence or continuance of an Event of
Default or Unmatured Event of Default, (iii) any adverse change in the condition
(financial or otherwise) of the Company or any Subsidiary thereof, (iv) any
termination of the Revolving Commitments or (v) any other circumstance,
happening or event whatsoever.

                  (b) Notwithstanding the provisions of CLAUSE (A) above, no
         Bank shall be required to purchase a participation interest in any
         Swing Line Loan if, prior to the making by the Swing Line Bank of such
         Swing Line Loan, the Swing Line Bank received written notice specifying
         that one or more of the conditions precedent to the making of such
         Swing Line Loan were not satisfied and, in fact, such conditions
         precedent were not satisfied at the time of the making of such Swing
         Line Loan.

2.5 COMMITMENTS SEVERAL. The failure of any Bank to make a requested Loan on any
date shall not relieve any other Bank of its obligation (if any) to make a Loan
on such date, but no Bank shall be responsible for the failure of any other Bank
to make any Loan to be made by such other Bank.

2.6 CERTAIN CONDITIONS. Notwithstanding any other provision of this Agreement,
no Bank shall have an obligation to make any Loan, and no Issuing Bank shall
have any obligation to issue any Letter of Credit, if an Event of Default or
Unmatured Event of Default exists.

3 SECTION NOTES EVIDENCING LOANS.

3.1 NOTES. The Loans of each Bank shall be evidenced by a promissory note
substantially in the form set forth in EXHIBIT A-1, with appropriate insertions,
payable to the order of such Bank in the principal amount of all of such Bank's
Loans hereunder.

3.2 RECORDKEEPING. Each Bank shall record in its records, or at its option on
the schedule attached to its Note, the date and amount of each Loan made by such
Bank, each repayment or conversion thereof and, in the case of each Eurodollar
Loan, the dates on which each Interest Period for such Loan shall begin and end.
The aggregate unpaid principal amount so recorded shall be rebuttable
presumptive evidence of the principal amount owing and unpaid on such Note. The
failure to so record any such amount or any error in so recording any such
amount shall not, however, limit or otherwise affect the obligations of the
Company hereunder or under any Note to repay the principal amount of the Loans
evidenced by such Note together with all interest accruing thereon.

                                       26
<PAGE>   34

4 SECTION INTEREST.

4.1 INTEREST RATES. The Company promises to pay interest on the unpaid principal
amount of each Loan for the period commencing on the date such Loan is advanced
until such Loan is paid in full as follows:

         (a) in the case of Revolving Loans and Term Loans, (i) at all times
         such Loan is a Base Rate Loan, at a rate per annum equal to the sum of
         the Base Rate from time to time in effect plus the applicable Base Rate
         Margin from time to time in effect; and (ii) at all times such Loan is
         a Eurodollar Loan, at a rate per annum equal to the sum of the
         Eurodollar Rate (Reserve Adjusted) applicable to each Interest Period
         for such Loan plus the Eurodollar Margin from time to time in effect;
         and

         (b) in the case of Swing Line Loans, at a rate per annum equal to the
         sum of the Base Rate from time to time in effect plus the applicable
         Base Rate Margin from time to time in effect;

PROVIDED that, unless the Required Banks otherwise agree in writing, at any time
an Event of Default exists the interest rate applicable to each Loan shall be
increased by 2%.

4.2 INTEREST PAYMENT DATES. Accrued interest on each Base Rate Loan and Swing
Line Loan shall be payable in arrears on the last Business Day of each calendar
month and at maturity. Accrued interest on each Eurodollar Loan shall be payable
on the last day of each Interest Period relating to such Loan (and, in the case
of a Eurodollar Loan with a six-month Interest Period, on the three-month
anniversary of the first day of such Interest Period) and at maturity. After
maturity, accrued interest on all Loans shall be payable on demand.

4.3 SETTING AND NOTICE OF EURODOLLAR RATES. The applicable Eurodollar Rate for
each Interest Period shall be determined by the Administrative Agent, and notice
thereof shall be given by the Administrative Agent promptly to the Company and
each Bank. Each determination of the applicable Eurodollar Rate by the
Administrative Agent shall be conclusive and binding upon the parties hereto, in
the absence of demonstrable error. The Administrative Agent shall, upon written
request of the Company or any Bank, deliver to the Company or such Bank a
statement showing the computations used by the Administrative Agent in
determining any applicable Eurodollar Rate hereunder.

4.4 COMPUTATION OF INTEREST. All determinations of interest for Base Rate Loans
and Swing Line Loans when the Base Rate is determined by the Reference Rate
shall be made on the basis of a year of 365 or 366 days, as the case may be, and
the actual number of days elapsed. All other computations of interest shall be
computed for the actual number of days elapsed on the basis of a year of 360
days. The applicable interest rate for each Base Rate Loan shall change
simultaneously with each change in the Base Rate.

5 SECTION FEES.

5.1 NON-USE FEE. The Company agrees to pay to the Administrative Agent for the
account of each Bank a non-use fee, for the period from the Effective Date to
the Revolving Termination Date, at a rate per annum equal to the Non-Use Fee
Rate in effect from time to time of the daily average of such Bank's Revolving

                                       27
<PAGE>   35

Percentage of the unused amount of the Revolving Commitment Amount. For purposes
of calculating usage under this Section, the Revolving Commitment Amount shall
be deemed used to the extent of the sum of the aggregate outstanding principal
amount of all Revolving Loans (not including Swing Line Loans) and the Stated
Amount of Letters of Credit at such time. Such non-use fee shall be payable in
arrears on the last Business Day of each calendar quarter and on the Revolving
Termination Date for any period then ending for which such non-use fee shall not
have theretofore been paid. The non-use fee shall be computed for the actual
number of days elapsed on the basis of a year of 360 days.

(a) LETTER OF CREDIT FEES. The Company agrees to pay to the Administrative Agent
for the account of the Banks pro rata according to their respective Revolving
Percentages a letter of credit fee for each Letter of Credit in an amount equal
to the applicable LC Fee Rate (based on the type of Letter of Credit) per annum
in effect from time to time of the undrawn amount of such Letter of Credit
(computed for the actual number of days elapsed on the basis of a year of 360
days); PROVIDED that, unless the Required Banks otherwise agree in writing, the
rate applicable to each Letter of Credit shall be increased by 2% at any time
that an Event of Default exists. Such letter of credit fee shall be payable in
arrears on the last Business Day of each calendar quarter and on the Revolving
Termination Date (and, if any Letter of Credit remains outstanding on the
Revolving Termination Date, thereafter on demand) for the period from the date
of the issuance of each Letter of Credit to the date such payment is due or, if
earlier, the date on which such Letter of Credit expired or was terminated.

(b) The Company agrees to pay each Issuing Bank a fronting fee for each Letter
of Credit issued by such Issuing Bank in the amount separately agreed to between
the Company and such Issuing Bank.

(c) In addition, with respect to each Letter of Credit, the Company agrees to
pay to the applicable Issuing Bank, for its own account, such fees and expenses
as such Issuing Bank customarily requires in connection with the issuance,
negotiation, processing and/or administration of letters of credit in similar
situations.

5.2 UP-FRONT AND FUNDING FEES. The Company agrees to pay to the Administrative
Agent for the account of the Banks pro rata according to their respective
percentages such up-front and funding fees as are mutually agreed to by the
Company and the Banks.

5.3 ADMINISTRATIVE AGENT'S FEES. The Company agrees to pay to the Administrative
Agent such agent's fees as are mutually agreed to from time to time by the
Company and the Administrative Agent.

6 SECTION REPAYMENT OF TERM LOANS; REDUCTION AND TERMINATION OR INCREASE OF THE
COMMITMENTS; PREPAYMENTS.

6.1 REPAYMENT OF TERM LOANS. The Term Loan of each Bank shall be repaid in
installments on the dates set forth on SCHEDULE 6.1(A) in the amounts set forth
opposite such dates, in each case in such Bank's Term Percentage of the
aggregate principal amount of the Term Loans to be repaid on the applicable
date.

6.2 VOLUNTARY REDUCTION OR TERMINATION OF THE REVOLVING COMMITMENTS. The Company
may from time to time on at least five Business Days' prior written notice
received by the Administrative Agent (which shall promptly advise each Bank

                                       28
<PAGE>   36

thereof) permanently reduce the Revolving Commitment Amount to an amount not
less than the Revolving Outstandings. Any such reduction shall be in an amount
not less than $5,000,000 or a higher integral multiple of $1,000,000. The
Company may at any time on like notice terminate the Revolving Commitments upon
payment in full of all Revolving Loans and Swing Line Loans and all other
obligations of the Company hereunder in respect of such Loans and cash
collateralization in full, pursuant to documentation in form and substance
reasonably satisfactory to the Issuing Banks, of all obligations arising with
respect to the Letters of Credit. All reductions of the Revolving Commitment
Amount shall reduce the Revolving Commitments pro rata among the Banks according
to their respective Revolving Percentages.

6.2.1 CHANGES IN COMMITMENT AMOUNT.

6.2.2 OPTIONAL INCREASE IN COMMITMENT AMOUNT. The Company may, by means of a
letter to the Agent substantially in the form of EXHIBIT I, request that the
Revolving Commitment Amount be increased by (a) increasing the Revolving
Commitment of one or more Banks which have agreed to such increase and/or (b)
adding one or more commercial banks or other Persons as a party hereto with a
Revolving Commitment in an amount agreed to by any such commercial bank or other
Person; provided that (i) no commercial bank or other Person shall be added as a
party hereto without the written consent of the Agent (which shall not be
unreasonably withheld) and (ii) in no event shall the Revolving Commitment
Amount exceed $30,000,000 without the written consent of all Banks. Any increase
in the Revolving Commitment Amount pursuant to this SECTION 6.2.2 shall be
effective three Business Days after the date on which the Agent has received and
accepted the applicable increase letter in the form of Annex 1 to EXHIBIT I (in
the case of an increase in the Revolving Commitment of an existing Bank) or
assumption letter in the form of Annex 2 to EXHIBIT I (in the case of the
addition of a commercial bank or other Person as a new Bank). The Agent shall
promptly notify the Company and the Banks of any increase in the amount of the
Revolving Commitment Amount pursuant to this SECTION 6.2.2 and of the Revolving
Commitment and Revolving Percentage of each Bank after giving effect thereto.
The Company acknowledges that, in order to maintain Loans in accordance with
each Bank's Revolving Percentage, a reallocation of the Revolving Commitments as
a result of a non-pro-rata increase in the Revolving Commitment Amount may
require prepayment of all or portions of certain Loans on the date of such
increase (and any such prepayment shall be subject to the provisions of SECTION
8.4). The Agent shall promptly notify all Banks of any increase in the Revolving
Commitment Amount pursuant to this SECTION 6.2.2.

6.3 PREPAYMENTS.

6.3.1 VOLUNTARY PREPAYMENTS. The Company may from time to time prepay Loans in
whole or in part, without premium or penalty, PROVIDED that the Company shall
give the Administrative Agent (which shall promptly advise each Bank) notice
thereof not later than 10:00 A.M. (or, in the case of prepayment of Swing Line
Loans, 12:00 noon), Chicago time, on the date of such prepayment (which shall be
a Business Day), specifying the Loans to be prepaid and the date and amount of
prepayment. Subject to SECTION 2.2.1, each partial prepayment of Revolving Loans
shall be in a principal amount of $500,000 or a higher integral multiple of
$100,000. Subject to SECTION 2.2.1, each partial prepayment of Term Loans shall

                                       29
<PAGE>   37

be in a principal amount of $500,000 or a higher integral multiple of $100,000.
Any prepayment of a Eurodollar Loan on a day other than the last day of an
Interest Period therefor shall include interest on the principal amount being
repaid and shall be subject to SECTION 8.4.

6.3.2 MANDATORY PREPAYMENTS

                  (a) Concurrently with the receipt by the Company or any
         Subsidiary of any Net Cash Proceeds from the issuance of equity, the
         Company shall make a prepayment of the Loans in an amount equal to the
         Specified Percentage (as defined below) of such Net Cash Proceeds for
         such Fiscal Year unless such equity is issued in connection with an
         acquisition permitted pursuant to SECTION 10.11 or such equity Net Cash
         Proceeds are used to fund an acquisition permitted pursuant to SECTION
         10.11 within 90 days of the issuance of such equity. The "Specified
         Percentage" shall be (i) 75% so long as the Funded Debt to Adjusted
         EBITDA Ratio is greater than or equal to 3.0 to 1.0, (ii) 50% so long
         as the Funded Debt to Adjusted EBITDA Ratio is greater than or equal to
         2.0 to 1 but less than 3.0 to 1.0, and (iii) 0% so long as the Funded
         Debt to Adjusted EBITDA Ratio is less than 2.0 to 1.0.

                  (b) Concurrently with the receipt by the Company of any Net
         Cash Proceeds from any Asset Sales in excess of $350,000 in any Fiscal
         Year individually or in a series of related transactions, the Company
         shall make a prepayment of the Loans in an amount equal to 100% of such
         Net Cash Proceeds;

                  (c) Within 90 days after the end of each Fiscal Year, the
         Company shall make a prepayment of the Loans in an amount equal to 50%
         of Excess Cash Flow for such Fiscal Year; PROVIDED that no such
         prepayment shall be required to the extent that the Funded Debt to
         Adjusted EBITDA Ratio calculated on a pro forma basis would be less
         than 2.75 to 1.0.

                  (d) If at any time the Revolving Outstandings exceed the
         Borrowing Base, the Company shall immediately make a mandatory
         prepayment of the principal amount of the Revolving Loans and L/C
         Advances, as appropriate, in the amount necessary to eliminate such
         excess (rounded upward, if necessary, to an integral multiple of
         $100,000).

6.3.4 APPLICATION OF MANDATORY PREPAYMENTS OF LOANS. Each mandatory prepayment
of Loans pursuant to CLAUSES (A) through (C) of SECTION 6.3.2 shall be applied
first, to the outstanding Term Loans on a pro rata basis with respect to each
remaining installment thereof until such Term Loans shall have been fully
prepaid and second, to the outstanding Revolving Loans with no reduction in the
Revolving Commitment Amount; PROVIDED that any Net Cash Proceeds from the sale
of Clean Earth, Inc. shall be applied first, to the outstanding Term Loans on a
pro rata basis with respect to each remaining installment thereof until such
Term Loans shall have been fully prepaid, second, to repay the amount
outstanding under the Stout Note until such Stout Note shall have been fully
repaid and third, to the outstanding Revolving Loans with no reduction in the
Revolving Commitment Amount. Prepayments shall be applied pro rata to the
applicable Loans of all Banks in accordance with their Percentages.

7 SECTION MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

7.1 MAKING OF PAYMENTS. All payments of principal of or interest on the Loans,
and of all non-use fees and Letter of Credit fees, shall be made by the Company
to the Administrative Agent in immediately available funds at the Administrative
Agent's Office not later than noon, Chicago time, on the date due; and funds
received after that hour shall be deemed to have been received by the
Administrative Agent on the next following Business Day. The Administrative
Agent shall promptly remit to each Bank its share of all such payments received
in collected funds by the Administrative Agent for the account of such Bank. All
payments under SECTION 8.1 shall be made by the Company directly to the Bank
entitled thereto.

7.2 APPLICATION OF CERTAIN PAYMENTS. Each payment of principal shall be applied
to such Loans as the Company shall direct by notice to be received by the
Administrative Agent on or before the date of such payment or, in the absence of
such notice, as the Administrative Agent shall determine in its discretion.
Concurrently with each remittance to any Bank of its share of any such payment,
the Administrative Agent shall advise such Bank as to the application of such
payment.

7.3 DUE DATE EXTENSION. Subject to the definition of "Interest Period", if any
payment of principal or interest with respect to any of the Loans, or of non-use
fees or Letter of Credit fees, falls due on a day which is not a Business Day,
then such due date shall be extended to the immediately following Business Day
and such extension of time shall be reflected in computing interest and fees.

7.4 FAILURE TO MAKE PAYMENTS. Unless the Company or any Bank has notified the
Administrative Agent prior to the date any payment to be made by it is due, that
it does not intend to remit such payment, the Administrative Agent may, in its
sole and absolute discretion, assume that the Company or Bank as the case may
be, has timely remitted such payment and may, in its sole and absolute
discretion and in reliance thereon, make available such payment to the Person
entitled thereto. If such payment was not in fact remitted to the Administrative
Agent in immediately available funds, then:

                  (i) if the Company failed to make such payment, each Bank
         shall forthwith on demand repay to the Administrative Agent the amount
         of such assumed payment made available to such Bank, together with
         interest thereon in respect of each day from and including the date
         such amount was made available by the Administrative Agent to such Bank
         to the date such amount is repaid to the Administrative Agent at the
         Federal Funds Rate; and

                  (ii) if any Bank failed to make such payment, the
         Administrative Agent shall be entitled to recover such corresponding
         amount on demand from such Bank. If such Bank does not pay such
         corresponding amount forthwith upon the Administrative Agent's demand
         therefore, the Administrative Agent promptly shall notify the Company,
         and the Company shall pay such corresponding amount to the
         Administrative Agent. The Administrative Agent also shall be entitled
         to recover from such Bank interest on such corresponding amount in
         respect of each day from the date such corresponding among was made
         available by the Administrative Agent to the Company to the date such
         corresponding amount is recovered by the Administrative Agent, (A) from

                                       31
<PAGE>   39

         such Bank at a rate per annum equal to the daily Federal Funds Rate and
         (B) from the Company, at a rate per annum equal to the interest rate
         applicable to such borrowing. Nothing herein shall be deemed to relieve
         any bank from its obligation to fulfill its Commitment or to prejudice
         any rights which the Administrative Agent or the Company may have
         against any Bank as a result of any default by such Bank hereunder.

7.5 SETOFF. The Company agrees that the Administrative Agent and each Bank have
all rights of set-off and bankers' lien provided by applicable law, and in
addition thereto, the Company agrees that at any time any Event of Default
exists, the Administrative Agent and each Bank may apply to the payment of any
obligations of the Company hereunder, whether or not then due, any and all
balances, credits, deposits, accounts or moneys of the Company then or
thereafter with the Administrative Agent or such Bank.

7.6 PRORATION OF PAYMENTS. If any Bank shall obtain any payment or other
recovery (whether voluntary, involuntary, by application of offset or otherwise,
but excluding any payment pursuant to SECTION 8.7 or 14.9 or any payment to the
Swing Line Bank in respect of a Swing Line Loan) on account of principal of or
interest on any Loan (or on account of its participation in any Letter of Credit
or Swing Line Loan) in excess of its pro rata share of payments and other
recoveries obtained by all Banks on account of principal of and interest on
Loans (or such participations) then held by them, such Bank shall purchase from
the other Banks such participation in the Loans (or sub-participations in
Letters of Credit or Swing Line Loans) held by them as shall be necessary to
cause such purchasing Bank to share the excess payment or other recovery ratably
with each of them; PROVIDED that if all or any portion of the excess payment or
other recovery is thereafter recovered from such purchasing Bank, the purchase
shall be rescinded and the purchase price restored to the extent of such
recovery.

(a) TAXES. All payments of principal of, and interest on, the Loans and all
other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and
other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, but excluding franchise taxes and
taxes imposed on or measured by any Bank's net income or receipts (all
non-excluded items being called "TAXES"). If any withholding or deduction from
any payment to be made by the Company hereunder is required in respect of any
Taxes pursuant to any applicable law, rule or regulation, then the Company will:

         (i) pay directly to the relevant authority the full amount required to
         be so withheld or deducted;

         (ii) promptly forward to the Administrative Agent an official receipt
         or other documentation satisfactory to the Administrative Agent
         evidencing such payment to such authority; and

         (iii) (except to the extent such withholding or deduction would not be
         required if such Bank's Exemption Representation were true) pay to the
         Administrative Agent for the account of the Banks such additional
         amount or amounts as is necessary to ensure that the net amount
         actually received by each Bank will equal the full amount such Bank
         would have received had no such withholding or deduction been required.

                                       32
<PAGE>   40

Moreover, if any Taxes are directly asserted against the Administrative Agent or
any Bank with respect to any payment received by the Administrative Agent or
such Bank hereunder, the Administrative Agent or such Bank may pay such Taxes
and the Company will (except to the extent such Taxes are payable by a Bank and
would not have been payable if such Bank's Exemption Representation were true)
promptly pay such additional amounts (including any penalty, interest and
expense) as is necessary in order that the net amount received by such Person
after the payment of such Taxes (including any Taxes on such additional amount)
shall equal the amount such Person would have received had such Taxes not been
asserted.

(b) If the Company fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent, for the account of the
respective Banks, the required receipts or other required documentary evidence,
the Company shall indemnify the Banks for any incremental Taxes, interest or
penalties that may become payable by any Bank as a result of any such failure.
For purposes of this SECTION 7.7, a distribution hereunder by the Administrative
Agent or any Bank to or for the account of any Bank shall be deemed a payment by
the Company.

(c) Each Bank represents and warrants (such Bank's "EXEMPTION REPRESENTATION")
to the Company and the Administrative Agent that, as of the date of this
Agreement (or, in the case of an Assignee, the date it becomes a party hereto),
it is entitled to receive payments hereunder without any deduction or
withholding for or on account of any Taxes imposed by the United States of
America or any political subdivision or taxing authority thereof.

(d) Upon the request from time to time of the Company or the Administrative
Agent, each Bank that is organized under the laws of a jurisdiction other than
the United States of America shall execute and deliver to the Company and the
Administrative Agent one or more (as the Company or the Administrative Agent may
reasonably request) United States Internal Revenue Service Forms 4224 or Forms
1001 or such other forms or documents, appropriately completed, as may be
applicable to establish the extent, if any, to which a payment to such Bank is
exempt from withholding or deduction of Taxes.

(e) If, and to the extent that, any Bank shall obtain a credit, relief or
remission for, or repayment of, any Taxes indemnified or paid by the Company
pursuant to this SECTION 7.7, such Bank agrees to promptly notify the Company
thereof and thereupon enter into negotiations in good faith with the Company to
determine the basis on which an equitable reimbursement of such Taxes can be
made to the Company.

8 SECTION INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR LOANS.

(a) INCREASED COSTS. If, after the date hereof, the adoption of any applicable
law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Bank (or any Eurodollar Office of such Bank) with
any request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency

         (A) shall subject any Bank (or any Eurodollar Office of such Bank) to
         any tax, duty or other charge with respect to its Eurodollar Loans, its
         Note or its obligation to make Eurodollar Loans, or shall change the
         basis of taxation of payments to any Bank of the principal of or
         interest on its Eurodollar Loans or any other amounts due under this
         Agreement in respect of its Eurodollar Loans or its obligation to make
         Eurodollar Loans (except for changes in the rate of tax on the overall
         net income of such Bank or its Eurodollar Office imposed by the
         jurisdiction in which such Bank's principal executive office or
         Eurodollar Office is located); or

         (B) shall impose, modify or deem applicable any reserve (including any
         reserve imposed by the FRB, but excluding any reserve included in the
         determination of interest rates pursuant to SECTION 4), special deposit
         or similar requirement against assets of, deposits with or for the
         account of, or credit extended by any Bank (or any Eurodollar Office of
         such Bank); or

         (C) shall impose on any Bank (or its Eurodollar Office) any other
         condition affecting its Eurodollar Loans, its Note or its obligation to
         make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or in the
case of Regulation D of the FRB, to impose a cost on) such Bank (or any
Eurodollar Office of such Bank) of making or maintaining any Eurodollar Loan, or
to reduce the amount of any sum received or receivable by such Bank (or its
Eurodollar Office) under this Agreement or under its Note with respect thereto,
then within 10 Business Days after demand by such Bank (which demand shall be
accompanied by a statement setting forth the basis for such demand and a
calculation of the amount thereof in reasonable detail, a copy of which shall be
furnished to the Administrative Agent), the Company shall pay directly to such
Bank such additional amount as will compensate such Bank for such increased cost
or such reduction.

(b) If any Bank shall reasonably determine that the adoption or phase-in of any
applicable law, rule or regulation regarding capital adequacy, or any change
therein, or any change in the interpretation or administration thereof by any
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Bank or any
Person controlling such Bank with any request or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on such Bank's or such controlling Person's capital as a consequence of
such Bank's obligations hereunder or under any Letter of Credit to a level below
that which such Bank or such controlling Person could have achieved but for such

                                       34
<PAGE>   42

adoption, change or compliance (taking into consideration such Bank's or such
controlling Person's policies with respect to capital adequacy) by an amount
deemed by such Bank or such controlling Person to be material, then from time to
time, within 10 Business Days after demand by such Bank (which demand shall be
accompanied by a statement setting forth the basis for such demand and a
calculation of the amount thereof in reasonable detail, a copy of which shall be
furnished to the Administrative Agent), the Company shall pay to such Bank such
additional amount or amounts as will compensate such Bank or such controlling
Person for such reduction.

8.2 BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR. If with respect to
any Interest Period:

         (a) deposits in Dollars (in the applicable amounts) are not being
         offered to the Administrative Agent in the interbank eurodollar market
         for such Interest Period, or the Administrative Agent otherwise
         reasonably determines (which determination, if made in good faith,
         shall be binding and conclusive on the Company) that by reason of
         circumstances affecting the interbank eurodollar market adequate and
         reasonable means do not exist for ascertaining the applicable
         Eurodollar Rate; or

         (b) Banks having an aggregate Percentage of 40% or more advise the
         Administrative Agent that the Eurodollar Rate (Reserve Adjusted) as
         determined by the Administrative Agent will not adequately and fairly
         reflect the cost to such Banks of maintaining or funding such
         Eurodollar Loans for such Interest Period (taking into account any
         amount to which such Banks may be entitled under SECTION 8.1) or that
         the making or funding of Eurodollar Loans has become impracticable as a
         result of an event occurring after the date of this Agreement which in
         the opinion of such Banks materially affects such Loans;

THEN the Administrative Agent shall promptly notify the other parties thereof
and, so long as such circumstances shall continue, (i) no Bank shall be under
any obligation to make or convert into Eurodollar Loans and (ii) on the last day
of the current Interest Period for each Eurodollar Loan, such Loan shall, unless
then repaid in full, automatically convert to a Base Rate Loan.

8.3 CHANGES IN LAW RENDERING EURODOLLAR LOANS UNLAWFUL. In the event that any
change in (including the adoption of any new) applicable laws or regulations, or
any change in the interpretation of applicable laws or regulations by any
governmental or other regulatory body charged with the administration thereof,
should make it (or in the good faith judgment of any Bank cause a substantial
question as to whether it is) unlawful for any Bank to make, maintain or fund
Eurodollar Loans, then such Bank shall promptly notify each of the other parties
hereto and, so long as such circumstances shall continue, (a) such Bank shall
have no obligation to make or convert into Eurodollar Loans (but shall make Base
Rate Loans concurrently with the making of or conversion into Eurodollar Loans
by the Banks which are not so affected, in each case in an amount equal to such

                                       35
<PAGE>   43

Bank's pro rata share of all Eurodollar Loans which would be made or converted
into at such time in the absence of such circumstances) and (b) on the last day
of the current Interest Period for each Eurodollar Loan of such Bank (or, in any
event, on such earlier date as may be required by the relevant law, regulation
or interpretation), such Eurodollar Loan shall, unless then repaid in full,
automatically convert to a Base Rate Loan. Each Base Rate Loan made by a Bank
which, but for the circumstances described in the foregoing sentence, would be a
Eurodollar Loan (an "AFFECTED LOAN") shall remain outstanding for the same
period as the Group of Eurodollar Loans of which such Affected Loan would be a
part absent such circumstances.

8.4 FUNDING LOSSES. The Company hereby agrees that upon demand by any Bank
(which demand shall be accompanied by a statement setting forth the basis for
the amount being claimed, a copy of which shall be furnished to the
Administrative Agent), the Company will indemnify such Bank against any net loss
or expense which such Bank may sustain or incur (including any net loss or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Bank to fund or maintain any Eurodollar Loan), as
reasonably determined by such Bank, as a result of (a) any payment, prepayment
or conversion of any Eurodollar Loan of such Bank on a date other than the last
day of an Interest Period for such Loan (including any conversion pursuant to
SECTION 8.3) or (b) any failure of the Company to borrow or continue, or to
convert any Loan into, a Eurodollar Loan on a date specified therefor in a
notice of borrowing, continuation or conversion pursuant to this Agreement. For
this purpose, all notices to the Administrative Agent pursuant to this Agreement
shall be deemed to be irrevocable.

8.5 RIGHT OF BANKS TO FUND THROUGH OTHER OFFICES. Each Bank may, if it so
elects, fulfill its commitment as to any Eurodollar Loan by causing a foreign
branch or affiliate of such Bank to make such Loan, PROVIDED that in such event
for the purposes of this Agreement such Loan shall be deemed to have been made
by such Bank and the obligation of the Company to repay such Loan shall
nevertheless be to such Bank and shall be deemed held by it, to the extent of
such Loan, for the account of such branch or affiliate.

8.6 DISCRETION OF BANKS AS TO MANNER OF FUNDING. Notwithstanding any provision
of this Agreement to the contrary, each Bank shall be entitled to fund and
maintain its funding of all or any part of its Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder shall be made as if such Bank had actually funded and
maintained each Eurodollar Loan during each Interest Period for such Loan
through the purchase of deposits having a maturity corresponding to such
Interest Period and bearing an interest rate equal to the Eurodollar Rate for
such Interest Period.

(a) MITIGATION OF CIRCUMSTANCES; REPLACEMENT OF AFFECTED BANK. Each Bank shall
promptly notify the Company and the Administrative Agent of any event of which
it has knowledge which will result in, and will use reasonable commercial
efforts available to it (and not, in such Bank's good faith judgment, otherwise
disadvantageous to such Bank) to mitigate or avoid, (i) any obligation by the
Company to pay any amount pursuant to SECTION 7.7 or 8.1 or (ii) the occurrence
of any circumstance of the nature described in SECTION 8.2 or 8.3 (and, if any
Bank has given notice of any such event described in CLAUSE (I) or (II) above
and thereafter such event ceases to exist, such Bank shall promptly so notify
the Company and the Administrative Agent). Without limiting the foregoing, each
Bank will designate a different funding office if such designation will avoid

                                       36
<PAGE>   44

(or reduce the cost to the Company of) any event described in CLAUSE (I) or (II)
of the preceding sentence and such designation will not, in such Bank's sole
good faith judgment, be otherwise disadvantageous to such Bank.

                  (b) At any time any Bank is an Affected Bank, the Company may
         replace such Affected Bank as a party to this Agreement with one or
         more other bank(s) or financial institution(s) reasonably satisfactory
         to the Administrative Agent (and upon notice from the Company such
         Affected Bank shall assign pursuant to an Assignment Agreement, and
         without recourse or warranty, its Commitment, its Loans, its Note, its

         singly or in the aggregate might reasonably be expected to have a
         Material Adverse Effect.

by a duly authorized representative of the Company as to the matters set out in
SECTION 11.2.1 (it being understood that each request by the Company for the
making of a Loan or the issuance of a Letter of Credit shall be deemed to
constitute a warranty by the Company that the conditions precedent set forth in
SECTION 11.2.1 will be satisfied at the time of the making of such Loan or the
issuance of such Letter of Credit), together with such other documents as the

commenced by the Company or such Subsidiary, it is consented to or acquiesced in
by the Company or such Subsidiary, or remains for 60 days undismissed; or the

rendered against the Company, or any Subsidiary and shall not have been paid,
discharged or vacated or had execution thereof stayed pending appeal within 30

individual who has been replaced by another individual or individuals reasonably
satisfactory to the Required Banks (it being understood that any such
replacement individual shall be deemed added to SCHEDULE 12.1.11 on the date of
approval thereof by the Required Banks).

12.2 EFFECT OF EVENT OF DEFAULT. If any Event of Default described in SECTION

shall immediately terminate and the Loans and all other obligations hereunder
shall become immediately due and payable and the Company shall become
immediately obligated to deliver to the Administrative Agent cash collateral in
an amount equal to the outstanding face amount of all Letters of Credit, all
without presentment, demand, protest or notice of any kind; and, if any other
Event of Default shall occur and be continuing, the Administrative Agent (upon
written request of the Required Banks) shall declare the Commitments (if they
have not theretofore terminated) to be terminated and/or declare all Loans and
all other obligations hereunder to be due and payable and/or demand that the
Company immediately deliver to the Administrative Agent cash collateral in
amount equal to the outstanding face amount of all Letters of Credit, whereupon
the Commitments (if they have not theretofore terminated) shall immediately
terminate and/or all Loans and all other obligations hereunder shall become
immediately due and payable and/or the Company shall immediately become
obligated to deliver to the Administrative Agent cash collateral in an amount
equal to the face amount of all Letters of Credit, all without presentment,
demand, protest or notice of any kind. The Administrative Agent shall promptly
advise the Company of any such declaration, but failure to do so shall not
impair the effect of such declaration. Notwithstanding the foregoing, the effect
as an Event of Default of any event described in SECTION 12.1.1 or SECTION
12.1.4 may be waived by the written concurrence of all of the Banks, and the
effect as an Event of Default of any other event described in this SECTION 12
may be waived by the written concurrence of the Required Banks. Any cash
collateral delivered hereunder shall be held by the Administrative Agent
(without liability for interest thereon) and applied to obligations arising in
connection with any drawing under a Letter of Credit. After the expiration or
termination of all Letters of Credit, such cash collateral shall be applied by
the Administrative Agent to any remaining obligations hereunder and any excess

SECTION 13.9) appoints, designates and authorizes the Administrative 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

         associated therewith. Each Issuing Bank shall have all of the benefits

         13 with respect to any acts taken or omissions suffered by such Issuing
         Bank in connection with Letters of Credit issued by it or proposed to
         be issued by it and the applications and agreements for letters of
         credit pertaining to such Letters of Credit as fully as if the term
         "Administrative Agent", as used in this SECTION 13, included such
         Issuing Bank with respect to such acts or omissions and (ii) as
         additionally provided in this Agreement with respect to the Issuing

         SECTION 13, included the Swing Line Bank with respect to such acts or
         omissions and (ii) as additionally provided in this Agreement with
         respect to the Swing Line Bank.

13.2 DELEGATION OF DUTIES. The Administrative Agent may execute any of its
duties under this Agreement or any other Loan Document by or through agents,

concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agent or
attorney-in-fact that it selects with reasonable care.

13.3 LIABILITY OF ADMINISTRATIVE AGENT. None of 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 or any other Loan Document or the
transactions contemplated hereby (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 or Affiliate 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
Administrative Agent under or in connection with, this Agreement or any other

                                       57
<PAGE>   65

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

13.4 RELIANCE BY ADMINISTRATIVE AGENT. The Administrative Agent shall be
entitled to rely, and shall be fully protected in relying, upon any writing,
resolution, notice, consent, certificate, affidavit, letter, telegram,
facsimile, 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 Administrative Agent. The Administrative 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 Required Banks as it deems appropriate and, if it so
requests, confirmation from the Banks of their obligation to indemnify the
Administrative Agent 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
Administrative 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 Required Banks and such request and
any action taken or failure to act pursuant thereto shall be binding upon all of
the Banks.

13.5 NOTICE OF DEFAULT. The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of any Event of Default or Unmatured Event
of Default except with respect to defaults in the payment of principal, interest
and fees required to be paid to the Administrative Agent for the account of the
Banks, unless the Administrative Agent shall have received written notice from a
Bank or the Company referring to this Agreement, describing such Event of
Default or Unmatured Event of Default and stating that such notice is a "notice
of default". The Administrative Agent will notify the Banks of its receipt of
any such notice. The Administrative Agent shall take such action with respect to
such Event of Default or Unmatured Event of Default as may be requested by the
Required Banks in accordance with SECTION 12; PROVIDED that unless and until the
Administrative Agent has received any such request, the Administrative Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Event of Default or Unmatured Event of Default as
it shall deem advisable or in the best interest of the Banks.

13.6 CREDIT DECISION. Each Bank acknowledges that none of the Agent-Related
Persons has made any representation or warranty to it, and that no act by the
Administrative Agent hereafter taken, including any review of the affairs of the
Company and its Subsidiaries, shall be deemed to constitute any representation
or warranty by any Agent-Related Person to any Bank. Each Bank represents to the
Administrative Agent that it has, independently and without reliance upon any
Agent-Related Person and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Company and its Subsidiaries, and all applicable bank
regulatory laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to the Company
hereunder. Each Bank also represents that it will, independently and without
reliance upon any Agent-Related Person and based on such documents and
information as it shall deem appropriate at the time, continue to make its own

                                       58
<PAGE>   66

credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigations as
it deems necessary to inform itself as to the business, prospects, operations,
property, financial and other condition and creditworthiness of the Company.
Except for notices, reports and other documents expressly herein required to be
furnished to the Banks by the Administrative Agent, the Administrative 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 or other condition or creditworthiness of the Company which may come
into the possession of any of the Agent-Related Persons.

13.7 INDEMNIFICATION. Whether or not the transactions contemplated hereby are
consummated, the Banks shall indemnify upon demand the Agent-Related Persons (to
the extent not reimbursed by or on behalf of the Company and without limiting
the obligation of the Company to do so), pro rata, from and against any and all
Indemnified Liabilities; PROVIDED that no Bank shall be liable for any payment
to the Agent-Related Person of any portion of the Indemnified Liabilities
resulting solely from such Person's gross negligence or willful misconduct.
Without limitation of the foregoing, each Bank shall reimburse the
Administrative Agent upon demand for its ratable share of any costs or
out-of-pocket expenses (including reasonable fees of attorneys for the
Administrative Agent (including the allocable costs of internal legal services
and all disbursements of internal counsel)) incurred by the Administrative 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 Administrative
Agent is not reimbursed for such expenses by or on behalf of the Company. The
undertaking in this Section shall survive repayment of the Loans, cancellation
of the Notes, any foreclosure under, or any modification, release or discharge
of, any or all of the Collateral Documents, any termination of this Agreement
and the resignation or replacement of the Administrative Agent.

                                       59
<PAGE>   67

         For the purposes of this SECTION 13.7, "INDEMNIFIED LIABILITIES" shall
mean: any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, charges, expenses and disbursements (including
reasonable fees of attorneys for the Administrative Agent (including the
allocable costs of internal legal services and all disbursements of internal
counsel)) of any kind or nature whatsoever which may at any time (including at
any time following repayment of the Loans and the termination, resignation or
replacement of the Administrative Agent or the replacement of any Bank) be
imposed on, incurred by or asserted against any Agent-Related Person in any way
relating to or arising out of this Agreement or any document contemplated by or
referred to herein, or the transactions contemplated hereby, or any action taken
or omitted by any such Person under or in connection with any of the foregoing,
including with respect to any investigation, litigation or proceeding (including
(a) any case, action or proceeding before any court or other governmental
authority relating to bankruptcy, reorganization, insolvency, liquidation,
receivership, dissolution, winding-up or relief of debtors, or (b) any general
assignment for the benefit of creditors, composition, marshalling of assets for
creditors, or other, similar arrangement in respect of its creditors generally
or any substantial portion of its creditors; undertaken under U.S. Federal,
state or foreign law, including the Bankruptcy Code, and including any appellate
proceeding) related to or arising out of this Agreement or the Commitments or
the use of the proceeds thereof, whether or not any Administrative Agent-Related
Person, any Bank or any of their respective officers, directors, employees,
counsel, agents or attorneys-in-fact is a party thereto.

13.8 ADMINISTRATIVE 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, acquire equity interests in and generally engage in any kind of
banking, trust, financial advisory, underwriting or other business with the
Company and its Subsidiaries and Affiliates as though Bank of America were not
the Administrative Agent, the Issuing Bank or the Swing Line Bank hereunder and
without notice to or consent of the Banks. The Banks acknowledge that, pursuant
to such activities, Bank of America or its Affiliates may receive information
regarding the Company or its Affiliates (including information that may be
subject to confidentiality obligations in favor of the Company or such
Subsidiary) and acknowledge that the Administrative Agent shall be under no
obligation to provide such information to them. With respect to their Loans,
Bank of America and its Affiliates shall have the same rights and powers under
this Agreement as any other Bank and may exercise the same as though Bank of
America were not the Administrative Agent and the Issuing Bank and the Swing
Line Bank, and the terms "Bank" and "Banks" include Bank of America and its
Affiliates, to the extent applicable, in their individual capacities.

13.9 SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent may, and at the
request of the Required Banks shall, resign as Administrative Agent upon 30
days' notice to the Banks. If the Administrative Agent resigns under this
Agreement, the Required Banks shall, with (so long as no Event of Default
exists) the consent of the Company (which shall not be unreasonably withheld or
delayed), appoint from among the Banks a successor agent for the Banks. If no
successor agent is appointed prior to the effective date of the resignation of
the Administrative Agent, the Administrative Agent may appoint, after consulting

                                       60
<PAGE>   68

with the Banks and the Company, a successor agent from among the Banks. Upon the
acceptance of its appointment as successor agent hereunder, such successor agent
shall succeed to all the rights, powers and duties of the retiring
Administrative Agent and the term "Administrative Agent" shall mean such
successor agent, and the retiring Administrative Agent's appointment, powers and
duties as Administrative Agent shall be terminated. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this SECTION 13 and SECTIONS 14.6 and 14.13 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Agreement. If no successor agent has accepted
appointment as Administrative Agent by the date which is 30 days following a
retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Banks shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Required Banks appoint a successor
agent as provided for above. Notwithstanding the foregoing, however, Bank of
America may not be removed as the Administrative Agent at the request of the
Required Banks unless Bank of America shall also simultaneously be replaced as
an "Issuing Bank" and the "Swing Line Bank" hereunder pursuant to documentation
in form and substance reasonably satisfactory to Bank of America.

13.10 WITHHOLDING TAX.

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

                           (i) if such Bank claims an exemption from, or a
                  reduction of, withholding tax under a United States tax
                  treaty, properly completed Internal Revenue Service ("IRS")
                  Forms 1001 and W-8 before the payment of any interest in the
                  first calendar year and before the payment of any interest in
                  each third succeeding calendar year during which interest may
                  be paid under this Agreement;

                           (ii) if such Bank claims that interest paid under
                  this Agreement is exempt from United States withholding tax
                  because it is effectively connected with a United States trade
                  or business of such Bank, two properly completed and executed
                  copies of IRS Form 4224 before the payment of any interest is
                  due in the first taxable year of such Bank and in each
                  succeeding taxable year of such Bank during which interest may
                  be paid under this Agreement, and IRS Form W-9; and

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

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

                                       61
<PAGE>   69

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

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

                  (d) If any Bank is entitled to a reduction in the applicable
         withholding tax, the Administrative Agent may withhold from any
         interest payment to such Bank an amount equivalent to the applicable
         withholding tax after taking into account such reduction. If the forms
         or other documentation required by SUBSECTION (A) of this Section are
         not delivered to the Administrative Agent, then the Administrative
         Agent may withhold from any interest payment to such Bank not providing
         such forms or other documentation an amount equivalent to the
         applicable withholding tax.

                  (e) If the IRS or any other governmental authority of the
         United States or any other jurisdiction asserts a claim that the
         Administrative Agent did not properly withhold tax from amounts paid to
         or for the account of any Bank (because the appropriate form was not
         delivered or was not properly executed, or because such Bank failed to
         notify the Administrative Agent of a change in circumstances which
         rendered the exemption from, or reduction of, withholding tax
         ineffective, or for any other reason) such Bank shall indemnify the
         Administrative Agent fully for all amounts paid, directly or
         indirectly, by the Administrative Agent as tax or otherwise, including
         penalties and interest, and including any taxes imposed by any
         jurisdiction on the amounts payable to the Administrative Agent under
         this Section, together with all costs and expenses (including
         reasonable fees of attorneys for the Administrative Agent (including
         the allocable costs of internal legal services and all disbursements of
         internal counsel)). The obligation of the Banks under this subsection
         shall survive the repayment of the Loans, cancellation of the Notes,
         any termination of this Agreement and the resignation or replacement of
         the Administrative Agent.

13.11 COLLATERAL MATTERS. The Banks irrevocably authorize the Administrative
Agent, at its option and in its discretion, to release any Lien granted to or

                                       62
<PAGE>   70

held by the Administrative Agent under any Collateral Document (i) upon
termination of the Commitments and payment in full of all Loans and all other
obligations of the Company hereunder and the expiration or termination of all
Letters of Credit; (ii) constituting property sold or to be sold or disposed of
as part of or in connection with any disposition permitted hereunder; or (iii)
subject to SECTION 14.1, if approved, authorized or ratified in writing by the
Required Banks. Upon request by the Administrative Agent at any time, the Banks
will confirm in writing the Administrative Agent's authority to release
particular types or items of collateral pursuant to this SECTION 13.11.

14 SECTION GENERAL.

14.1 WAIVER; AMENDMENTS. No delay on the part of the Administrative Agent or any
Bank in the exercise of any right, power or remedy shall operate as a waiver
thereof, nor shall any single or partial exercise by any of them of any right,
power or remedy preclude other or further exercise thereof, or the exercise of
any other right, power or remedy. No amendment, modification or waiver of, or
consent with respect to, any provision of this Agreement or the Notes shall in
any event be effective unless the same shall be in writing and signed and
delivered by Banks having an aggregate Total Percentage of not less than the
aggregate Total Percentage expressly designated herein with respect thereto or,
in the absence of such designation as to any provision of this Agreement or the
Notes, by the Required Banks, and then any such amendment, modification, waiver
or consent shall be effective only in the specific instance and for the specific
purpose for which given. No amendment, modification, waiver or consent shall
change or extend the Commitment of any Bank without the consent of such Bank. No
amendment, modification, waiver or consent shall modify the allocation of any
payment between the Term Loans without the consent of such Banks holding more
than 66-2/3% of the aggregate outstanding principal amount of the Term Loans. No
amendment, modification, waiver or consent shall (i) extend the date for payment
of any principal of or interest on any Loan or any fees payable hereunder, (ii)
reduce the principal amount of any Loan, the rate of interest thereon or any
fees payable hereunder, (iii) release the Guaranty (other than with respect to a
Guarantor which ceases to be a Subsidiary as a result of a transaction permitted
hereunder) or all or substantially all of the collateral granted under the
Collateral Documents or (iv) reduce the aggregate Total Percentage required to
effect an amendment, modification, waiver or consent without, in each case, the
consent of all Banks. No provisions of SECTION 13 or other provision of this
Agreement affecting the Administrative Agent in its capacity as such shall be
amended, modified or waived without the consent of the Administrative Agent. No
provision of this Agreement relating to the rights or duties of an Issuing Bank
in its capacity as such shall be amended, modified or waived without the consent
of such Issuing Bank. No provision of this Agreement affecting the Swing Line
Bank in its capacity as such shall be amended, modified or waived without the
written consent of the Swing Line Bank.

14.2 CONFIRMATIONS. The Company and each holder of a Note agree from time to
time, upon written request received by it from the other, to confirm to the
other in writing (with a copy of each such confirmation to the Administrative
Agent) the aggregate unpaid principal amount of the Loans then outstanding under
such Note.

14.3 NOTICES. Except as otherwise provided in SECTIONS 2.2 and 2.3, all notices
hereunder shall be in writing (including facsimile transmission) and shall be
sent to the applicable party at its address shown on SCHEDULE 14.3 or at such
other address as such party may, by written notice received by the other

                                       63
<PAGE>   71

parties, have designated as its address for such purpose. Notices sent by
facsimile transmission shall be deemed to have been given when sent and receipt
of such facsimile is confirmed; notices sent by mail shall be deemed to have
been given three Business Days after the date when sent by registered or
certified mail, postage prepaid; and notices sent by hand delivery or overnight
courier service shall be deemed to have been given when received. For purposes
of SECTIONS 2.2 and 2.3, the Administrative Agent and the Swing Line Bank shall
be entitled to rely on telephonic instructions from any person that the
Administrative Agent or the Swing Line Bank in good faith believes is an
authorized officer or employee of the Company, and the Company shall hold the
Administrative Agent, the Swing Line Bank and each other Bank harmless from any
loss, cost or expense resulting from any such reliance.

14.4 COMPUTATIONS. Where the character or amount of any asset or liability or
item of income or expense is required to be determined, or any consolidation or
other accounting computation is required to be made, for the purpose of this
Agreement, such determination or calculation shall, to the extent applicable and
except as otherwise specified in this Agreement, be made in accordance with
GAAP, consistently applied; PROVIDED that if the Company notifies the
Administrative Agent that the Company wishes to amend any covenant in SECTION 10
to eliminate or to take into account the effect of any change in GAAP on the
operation of such covenant (or if the Administrative Agent notifies the Company
that the Required Banks wish to amend SECTION 10 for such purpose), then the
Company's compliance with such covenant shall be determined on the basis of GAAP
in effect immediately before the relevant change in GAAP became effective, until
either such notice is withdrawn or such covenant is amended in a manner
satisfactory to the Company and the Required Banks.

14.5 REGULATION U. Each Bank represents that it in good faith is not relying,
either directly or indirectly, upon any Margin Stock as collateral security for
the extension or maintenance by it of any credit provided for in this Agreement.

14.6 COSTS, EXPENSES AND TAXES. The Company agrees to pay on demand all
reasonable out-of-pocket costs and expenses of the Administrative Agent and the
Lead Arranger (including the reasonable fees and charges of counsel for the
Administrative Agent and the Lead Arranger and of local counsel, if any, who may
be retained by said counsel) in connection with the preparation, execution,
delivery and administration of this Agreement, the other Loan Documents and all
other documents provided for herein or delivered or to be delivered hereunder or
in connection herewith (including any amendments, supplements or waivers to any
Loan Documents), and all reasonable out-of-pocket costs and expenses (including
reasonable attorneys' fees, court costs and other legal expenses and allocated
costs of staff counsel) incurred by the Administrative Agent and each Bank after
an Event of Default in connection with the enforcement of this Agreement, the
other Loan Documents or any such other documents. Each Bank agrees to reimburse
the Administrative Agent for such Bank's pro rata share (based on its respective
Total Percentage) of any such costs and expenses of the Administrative Agent not
paid by the Company. In addition, the Company agrees to pay, and to save the
Administrative Agent, the Lead Arranger and the Banks harmless from all
liability for, (a) any stamp or other taxes (excluding income taxes and
franchise taxes based on net income) which may be payable in connection with the
execution and delivery of this Agreement, the borrowings hereunder, the issuance

                                       64
<PAGE>   72

of the Notes or the execution and delivery of any other Loan Document or any
other document provided for herein or delivered or to be delivered hereunder or
in connection herewith and (b) any fees of the Company's auditors in connection
with any reasonable exercise by the Administrative Agent and the Banks of their
rights pursuant to SECTION 10.2. All obligations provided for in this SECTION
14.6 shall survive repayment of the Loans, cancellation of the Notes and any
termination of this Agreement.

14.7 SUBSIDIARY REFERENCES. The provisions of this Agreement relating to
Subsidiaries shall apply only during such times as the Company has one or more
Subsidiaries.

14.8 CAPTIONS. Section captions used in this Agreement are for convenience only
and shall not affect the construction of this Agreement.

14.9 ASSIGNMENTS; PARTICIPATIONS.

14.9.1 ASSIGNMENTS. Any Bank may, with the prior written consent of the
Administrative Agent and, so long as no Unmatured Event of Default or Event of
Default has occurred and is continuing, the Company (which consents shall not be
unreasonably delayed or withheld), at any time assign and delegate to one or
more commercial banks or other Persons (any Person to whom such an assignment
and delegation is to be made being herein called an "ASSIGNEE"), all or any
fraction of such Bank's Loans and Commitment (which assignment and delegation
shall be of a constant, and not a varying, percentage of all the assigning
Bank's Loans and Commitment) in a minimum aggregate amount equal to the lesser
of (i) the amount of the assigning Bank's remaining Commitment and Term Loans
and (ii) $5,000,000; PROVIDED that (a) no assignment and delegation may be made
to any Person if, at the time of such assignment and delegation, the Company
would be obligated to pay any greater amount under SECTION 7.7 or SECTION 8 to
the Assignee than the Company is then obligated to pay to the assigning Bank
under such Sections (and if any assignment is made in violation of the
foregoing, the Company will not be required to pay the incremental amounts) and
(b) the Company and the Administrative Agent shall be entitled to continue to
deal solely and directly with such Bank in connection with the interests so
assigned and delegated to an Assignee until the date when all of the following
conditions shall have been met:

                  (x) five Business Days (or such lesser period of time as the
         Administrative Agent and the assigning Bank shall agree) shall have
         passed after written notice of such assignment and delegation, together
         with payment instructions, addresses and related information with
         respect to such Assignee, shall have been given to the Company and the
         Administrative Agent by such assigning Bank and the Assignee,

                  (y) the assigning Bank and the Assignee shall have executed
         and delivered to the Company and the Administrative Agent an assignment
         agreement substantially in the form of EXHIBIT G (an "ASSIGNMENT
         AGREEMENT"), together with any documents required to be delivered
         thereunder, which Assignment Agreement shall have been accepted by the
         Administrative Agent, and

                  (z) the assigning Bank or the Assignee shall have paid the
         Administrative Agent a processing fee of $3,500.

From and after the date on which the conditions described above have been met,
(x) such Assignee shall be deemed automatically to have become a party hereto
and, to the extent that rights and obligations hereunder have been assigned and
delegated to such Assignee pursuant to such Assignment Agreement, shall have the
rights and obligations of a Bank hereunder, and (y) the assigning Bank, to the
extent that rights and obligations hereunder have been assigned and delegated by

                                       65
<PAGE>   73

it pursuant to such Assignment Agreement, shall be released from its obligations
hereunder. Within five Business Days after the effectiveness of any assignment
and delegation to a Person that is not currently a Bank hereunder, the Company
shall execute and deliver to the Administrative Agent (for delivery to the
Assignee) a new Note dated the effective date of such assignment. Any attempted
assignment and delegation not made in accordance with this SECTION 14.9.1 shall
be null and void.

         Notwithstanding the foregoing provisions of this SECTION 14.9.1 or any
other provision of this Agreement, any Bank may at any time assign all or any
portion of its Loans and its Note to a Federal Reserve Bank (but no such
assignment shall release any Bank from any of its obligations hereunder).

14.9.2 PARTICIPATIONS. Any Bank may at any time sell to one or more commercial
banks or other Persons participating interests in any Loan owing to such Bank,
the Note held by such Bank, the Commitment of such Bank, the direct or
participation interest of such Bank in any Letter of Credit or any other
interest of such Bank hereunder (any Person purchasing any such participating
interest being herein called a "PARTICIPANT"); PROVIDED that any Bank selling
any such participating interest shall give notice thereof to the Company. In the
event of a sale by a Bank of a participating interest to a Participant, (x) such
Bank shall remain the holder of its Note for all purposes of this Agreement, (y)
the Company and the Administrative Agent shall continue to deal solely and
directly with such Bank in connection with such Bank's rights and obligations
hereunder and (z) all amounts payable by the Company shall be determined as if
such Bank had not sold such participation and shall be paid directly to such
Bank. No Participant shall have any direct or indirect voting rights hereunder
except with respect to any of the events (excluding the events described in
CLAUSES (I) through (IV) thereof) described in the fourth sentence of SECTION
14.1. Each Bank agrees to incorporate the requirements of the preceding sentence
into each participation agreement which such Bank enters into with any
Participant. The Company agrees that if amounts outstanding under this Agreement
and the Notes are due and payable (as a result of acceleration or otherwise),
each Participant shall be deemed to have the right of setoff in respect of its
participating interest in amounts owing under this Agreement, any Note and with
respect to any Letter of Credit to the same extent as if the amount of its
participating interest were owing directly to it as a Bank under this Agreement
or such Note; PROVIDED that such right of setoff shall be subject to the
obligation of each Participant to share with the Banks, and the Banks agree to
share with each Participant, as provided in SECTION 7.5. The Company also agrees
that each Participant shall be entitled to the benefits of SECTION 7.6 and
SECTION 8 as if it were a Bank (provided that no Participant shall receive any
greater compensation pursuant to SECTION 7.6 or SECTION 8 than would have been
paid to the participating Bank if no participation had been sold).

14.10 GOVERNING LAW. This Agreement and each Note shall be a contract made under
and governed by and construed and interpreted in accordance with, the laws of
the State of Illinois applicable to contracts made and to be performed entirely
within such State. Whenever possible each provision of this Agreement shall be

                                       66
<PAGE>   74

interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement shall be prohibited by or invalid under
applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement. All obligations of the Company
and rights of the Administrative Agent and the Banks expressed herein or in any
other Loan Document shall be in addition to and not in limitation of those
provided by applicable law.

14.11 COUNTERPARTS. This Agreement may be executed in any number of counterparts
and by the different parties hereto on separate counterparts and each such
counterpart shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same Agreement.

14.12 SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the Company,
the Banks and their respective successors and assigns, and shall inure to the
benefit of the Company, the Banks and the Administrative Agent and the
successors and assigns of the Banks and the Administrative Agent.

14.13 INDEMNIFICATION BY THE COMPANY.

         (a) In consideration of the execution and delivery of this Agreement by
         the Administrative Agent and the Banks and the agreement to extend the
         Commitments provided hereunder, the Company hereby agrees to indemnify,
         exonerate and hold the Administrative Agent, the Lead Arranger, each
         Bank and each of the officers, directors, employees, Affiliates and
         agents of the Administrative Agent and each Bank (each a "BANK PARTY")
         free and harmless from and against any and all actions, causes of
         action, suits, losses, liabilities, damages and expenses, including
         reasonable attorneys' fees and charges and, without duplication,
         allocated costs of staff counsel (collectively, for purposes of this
         SECTION 14.13, called the "INDEMNIFIED LIABILITIES"), incurred by the
         Bank Parties or any of them as a result of, or arising out of, or
         relating to (i) any tender offer, merger, purchase of stock, purchase
         of assets or other similar transaction financed or proposed to be
         financed in whole or in part, directly or indirectly, with the proceeds
         of any of the Loans, (ii) the use, handling, release, emission,
         discharge, transportation, storage, treatment or disposal of any
         Hazardous Substance at any property owned or leased by the Company or
         any Subsidiary, (iii) any violation of any Environmental Laws with
         respect to conditions at any property owned or leased by the Company or
         any Subsidiary or the operations conducted thereon, (iv) the
         investigation, cleanup or remediation of offsite locations at which the
         Company or any Subsidiary or their respective predecessors are alleged
         to have directly or indirectly disposed of hazardous substances or (v)
         the execution, delivery, performance or enforcement of this Agreement
         or any other Loan Document by any of the Bank Parties, except for any
         such Indemnified Liabilities arising on account of any such Bank
         Party's gross negligence or willful misconduct. If and to the extent
         that the foregoing undertaking may be unenforceable for any reason, the
         Company hereby agrees to make the maximum contribution to the payment
         and satisfaction of each of the Indemnified Liabilities which is
         permissible under applicable law. Nothing set forth above shall be
         construed to relieve any Bank Party from any obligation it may have
         under this Agreement.

                                       67
<PAGE>   75

         (b) All obligations provided for in this SECTION 14.13 shall survive
         repayment of the Loans, cancellation of the Notes, any foreclosure
         under, or any modification, release or discharge of any or all of the
         Collateral Documents and any termination of this Agreement.

14.14 INTEREST. (a) It is the intention of the parties hereto that each Bank
shall conform strictly to usury laws applicable to it. Accordingly, the parties
hereto stipulate and agree that none of the terms and provisions contained in
this Agreement or any Note shall ever be construed to create a contract to pay
any Bank for the use, forbearance or detention of money a rate in excess of the
Highest Lawful Rate applicable to such Bank, and that for purposes hereof,
"interest" shall include the aggregate of all charges or other consideration
which constitute interest under applicable laws and are contracted for, taken,
reserved, charged or received under this Agreement, the applicable Note or
otherwise in connection with the transactions contemplated by this Agreement.
Further, if the transactions contemplated hereby would be usurious as to any
Bank under the laws applicable to it, then notwithstanding anything to the
contrary in this Agreement or the applicable Note, or any agreement or document
entered into in connection herewith or therewith, it is agreed as follows: the
aggregate of all consideration which constitutes interest under the laws
applicable to such Bank that is contracted for, taken, reserved, charged or
received by such Bank under this Agreement or the applicable Note, or otherwise
in connection herewith or therewith, shall under no circumstances exceed the
maximum amount allowed by the laws applicable to such Bank, and any excess shall
be credited by such Bank on the principal amount of the indebtedness of the
Company owed to such Bank (or, if the principal amount of all such indebtedness
shall have been paid in full, to the extent such interest has been received by
such Bank it shall be refunded by such Bank to the Company). The provisions of
this SECTION 14.14(A) shall control over all other provisions of this Agreement,
the Notes and any other agreement or document which may be in apparent conflict
herewith. The parties further stipulate and agree that, without limitation of
the foregoing, all calculations of the rate or amount of interest contracted
for, taken, reserved, charged or received under this Agreement, each Note and
any other applicable agreement or document which are made for the purpose of
determining whether such rate or amount exceeds the Highest Lawful Rate shall be
made, to the extent permitted by applicable law, by amortizing, prorating,
allocating and spreading during the period of the full stated term of the
indebtedness of the Company to the applicable Bank, and if longer and if
permitted by applicable law, until payment in full, all interest at any time so
contracted for, taken, reserved, charged or received.

                                       68
<PAGE>   76

                  (b) If at any time the effective rate of interest which would
         otherwise apply to any indebtedness evidenced by any Note issued to any
         Bank would exceed the Highest Lawful Rate applicable to such Bank
         (taking into account the interest rate applicable to such indebtedness
         pursuant to the other provisions of this Agreement, plus all additional
         charges and consideration which have been contracted for, taken,
         reserved, charged or received under this Agreement or such Note (the
         "Additional Charges") which constitute interest with respect to such
         indebtedness), the effective interest rate to apply to such
         indebtedness shall be limited to the Highest Lawful Rate, but any
         subsequent reductions in the interest rate applicable to such
         indebtedness shall not reduce the effective interest rate to apply to
         such indebtedness below the Highest Lawful Rate applicable to such Bank
         until the total amount of interest accrued on such indebtedness equals
         the amount of interest which would have accrued if the interest rate
         from time to time applicable to such indebtedness had at all times been
         in effect with respect to such indebtedness pursuant to the other
         provisions of this Agreement and if such Bank had collected all
         Additional Charges called for under this Agreement and its Note. If at
         maturity or final payment of any Note issued to any Bank the total
         amount of interest accrued on such Note (including amounts designated
         as "interest" plus any Additional Charges which constitute interest,
         and taking into account the limitations of the first sentence of this
         SECTION 14.14(B)) is less than the total amount of interest which would
         have accrued if the interest rate or interest rates applicable to the
         indebtedness from time to time outstanding under such Note had at all
         times been in effect pursuant to the other provisions of this
         Agreement, then the Company agrees, to the fullest extent permitted by
         the laws applicable to such Bank, to pay to such Bank an amount equal
         to the difference between (i) the lesser of (1) the amount of interest
         which would have accrued on such Note if the Highest Lawful Rate had at
         all times been in effect (but excluding, for purposes of calculating
         such amount of interest, any Additional Charges which constitute
         interest with respect to such Note), or (2) the amount of interest
         which would have accrued on such Note if the interest rate or interest
         rates applicable to the indebtedness from time to time outstanding
         under such Note had at all times been in effect pursuant to the other
         provisions of this Agreement (including amounts designated as
         "interest" plus any Additional Charges which constitute interest with
         respect to such Note) less (ii) the amount of interest actually accrued
         on such Note (including amounts designated as "interest" plus any
         Additional Charges which constitute interest with respect to such
         Note).

14.15 FORUM SELECTION AND CONSENT TO JURISDICTION. ANY LITIGATION BASED HEREON,
OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN
DOCUMENT, SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE

COMPANY HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED
BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE LAYING OF VENUE
OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM
THAT ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE
EXTENT THAT THE COMPANY HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM

NOTICE, ATTACHMENT PRIOR TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR
OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, THE COMPANY HEREBY
IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS.

14.16 WAIVER OF JURY TRIAL. EACH OF THE COMPANY, THE ADMINISTRATIVE AGENT AND
EACH BANK HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING
TO ENFORCE OR DEFEND ANY RIGHTS UNDER THIS AGREEMENT, ANY NOTE, ANY OTHER LOAN
DOCUMENT AND ANY AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH

FROM ANY BANKING RELATIONSHIP EXISTING IN CONNECTION WITH ANY OF THE FOREGOING,
AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT AND
NOT BEFORE A JURY.
