the excess of $15,000,000 over the aggregate amount of such additional
Commitments accepted in

                                      -39-
<PAGE>   48

accordance with the terms of this Section. Upon receipt of such notice, the
Syndication Agent shall use commercially reasonable efforts to arrange for the
Lenders or other Eligible Institutions to provide such additional Commitments;
provided, however, that the Syndication Agent will first offer each of the
Lenders that then has a Percentage in excess of zero with respect to the
applicable Tranche a pro rata portion of any such additional Commitments.
Alternatively, CSFB may commit to provide the full amount of the requested
additional Commitments and then offer portions of such additional Commitments to
the Lenders or other Eligible Institutions, subject to the proviso to the
immediately preceding sentence. Nothing contained in this Section or otherwise
in this Agreement is intended to commit any Lender or any Agent to provide any
portion of any such additional Commitments. If and to the extent that any
Lenders and/or other Eligible Institutions agree, in their sole discretion, to
severally provide any such additional Commitments, (i) in the case of any
Additional Term A Loan Commitment or Additional Term B Loan Commitment, upon the
making of any Additional Term Loans pursuant to such Additional Term Loan
Commitment, the Administrative Agent will adjust the amortization schedule
referenced in clause (e) of Section 3.1.1, so that the Borrower will repay an
additional amount on each Quarterly Payment Date occurring subsequent to the
making of such Additional Term Loans equal to the product of (x) a fraction (1)
the numerator of which is the amount of Initial Term Loans of the applicable
Tranche would have otherwise been due on such Quarterly Payment Date (without
giving effect to any adjustment made to the amount of Initial Term Loans due on
such Quarterly Payment Date as a result of any mandatory or voluntary
prepayment) and (2) the denominator of which is the aggregate amount of all
outstanding Initial Term Loans multiplied by (y) the aggregate principal amount
of such Additional Term Loans (provided that in any event any such Additional
Term Loans outstanding on the Stated Maturity Date for the applicable Tranche
shall be due on such Stated Maturity Date), (ii) in the case of an increase in
the Revolving Loan Commitment Amount, (A) the Revolving Loan Commitment Amount
shall be increased by the amount of the additional Revolving Loan Commitments
agreed to be so provided, (B) the Percentages of the respective Lenders in
respect of the increased Revolving Loan Commitment Amount shall be
proportionally adjusted (provided, however, that the amount equal to the
adjusted Percentage of a Lender in respect of Revolving Loans multiplied by the
Revolving Loan Commitment Amount as increased pursuant to clause (A) may not
exceed the amount equal to the Percentage of such Lender in respect of Revolving
Loans immediately prior to any adjustment made pursuant to this clause (B)
multiplied by the Revolving Loan Commitment Amount immediately prior to the
corresponding increase thereof pursuant to clause (A) without the consent of
such Lender) and such adjustment shall be recorded in the Register and (C) at
such time and in such manner as the Borrower and the Syndication Agent shall
agree (it being understood that the Borrower and the Agents will use
commercially reasonable efforts to avoid the prepayment or assignment of any
LIBO Rate Loan on a day other than the last day of the Interest Period
applicable thereto), the Lenders shall assign and assume outstanding Revolving
Loans and participations in outstanding Letters of Credit so as to cause the
amounts of such Revolving Loans and participations in Letters of Credit held by
each Lender with a Percentage in excess of zero of the Revolving Loan Commitment
to conform to its Percentage of the Revolving Loan Commitment and (iii) the
Borrower shall execute and deliver any additional Notes, other amendments or
modifications to any Loan Document, and any other

                                      -40-
<PAGE>   49

certificates, consents or legal opinions as the Agents may reasonably request.
Notwithstanding anything to the contrary in this Section, the interest
applicable to any Additional Term Loan of either type shall not exceed the rate
of interest applicable to the Initial Term B Loans of such type by more than 25
basis points.

         SECTION 2.3. Borrowing Procedures and Funding Maintenance. Loans (other
than Swing Line Loans) shall be made by the Lenders in accordance with Section
2.3.1, and Swing Line Loans shall be made by the Swing Line Lender in accordance
with Section 2.3.2.

         SECTION 2.3.1. Term Loans and Revolving Loans. By delivering a
Borrowing Request to the Administrative Agent on or before 9:00 a.m., San
Francisco time, on a Business Day, the Borrower may from time to time
irrevocably request, on not less than one Business Day's notice (in the case of
Base Rate Loans) or three Business Days' notice (in the case of LIBO Rate Loans)
nor more than five Business Days' notice (in the case of any Loans) that a
Borrowing be made in a minimum amount of $1,000,000 and an integral multiple of
$500,000, or in the unused amount of the applicable Commitment. On the terms and
subject to the conditions of this Agreement, each Borrowing shall be comprised
of the type of Loans, and shall be made on the Business Day, specified in such
Borrowing Request. On or before 11:00 a.m. (San Francisco time) on such Business
Day each Lender shall deposit with the Administrative Agent same day funds in an
amount equal to such Lender's Percentage of the requested Borrowing. Such
deposit will be made to an account which the Administrative Agent shall specify
from time to time by notice to the Lenders. To the extent funds are received
from the Lenders, the Administrative Agent shall make such funds available to
the Borrower by wire transfer to the accounts the Borrower shall have specified
in its Borrowing Request. No Lender's obligation to make any Loan shall be
affected by any other Lender's failure to make any Loan.

         SECTION 2.3.2. Swing Line Loans. (a) By telephonic notice to the Swing
Line Lender on or before 1:00 p.m., San Francisco time, on the Business Day the
proposed Swing Line Loan is to be made, promptly followed (within one Business
Day) by the delivery of a confirming Borrowing Request to the Swing Line Lender,
the Borrower may from time to time irrevocably request that a Swing Line Loan be
made by the Swing Line Lender. All Swing Line Loans shall be made as Base Rate
Loans and shall not be entitled to be converted into LIBO Rate Loans. The
proceeds of each Swing Line Loan shall be made available by the Swing Line
Lender, by 3:00 p.m., San Francisco time, on the Business Day telephonic notice
is received by it as provided in this clause (a), to the Borrower by wire
transfer to the account the Borrower shall have specified in its notice
therefor.

         (b) If (i) any Swing Line Loan shall be outstanding on the last
Business Day of any week, or (ii) any Default shall occur and be continuing,
each Lender with a Revolving Loan Commitment (other than the Swing Line Lender)
irrevocably agrees that it will, at the request of the Swing Line Lender and
upon notice from the Administrative Agent, unless such Swing Line Loan shall
have been earlier repaid, make a Revolving Loan (which shall initially be funded
as a Base Rate Loan) in an amount equal to such Lender's Percentage of the
aggregate principal

                                      -41-
<PAGE>   50

amount of all such Swing Line Loans then outstanding (such outstanding Swing
Line Loans hereinafter referred to as the "Refunded Swing Line Loans");
provided, that the Swing Line Lender shall not request, and no Lender with a
Revolving Loan Commitment shall make, any Refunded Swing Line Loan if, after
giving effect to the making of such Refunded Swing Line Loan, the sum of all
Swing Line Loans and Revolving Loans made by such Lender, plus such Lender's
Percentage of the aggregate amount of all Letter of Credit Outstandings, would
exceed such Lender's Percentage of the then existing Revolving Loan Commitment
Amount. On or before 1:00 p.m. (San Francisco time) on the first Business Day
following receipt by each Lender of a request to make Revolving Loans as
provided in the preceding sentence, each such Lender with a Revolving Loan
Commitment shall deposit in an account specified by the Swing Line Lender the
amount so requested in same day funds and such funds shall be applied by the
Swing Line Lender to repay the Refunded Swing Line Loans. At the time the
aforementioned Lenders make the above referenced Revolving Loans, the Swing Line
Lender shall be deemed to have made, in consideration of the making of the
Refunded Swing Line Loans, a Revolving Loan in an amount equal to the Swing Line
Lender's Percentage of the aggregate principal amount of the Refunded Swing Line
Loans. Upon the making (or deemed making, in the case of the Swing Line Lender)
of any Revolving Loans pursuant to this clause (b), the amount so funded shall
become outstanding under such Lender's Revolving Note and shall no longer be
owed under the Swing Line Note. All interest payable with respect to any
Revolving Loans made (or deemed made, in the case of the Swing Line Lender)
pursuant to this clause (b) shall be appropriately adjusted to reflect the
period of time during which the Swing Line Lender had outstanding Swing Line
Loans in respect of which such Revolving Loans were made. Each Lender's
obligation (in the case of Lenders with a Revolving Loan Commitment) to make the
Revolving Loans referred to in this clause (b) shall be absolute and
unconditional and shall not be affected by any circumstance, including, without
limitation, (i) any set-off, counterclaim, recoupment, defense or other right
which such Lender may have against the Swing Line Lender, the Borrower or any
other Person for any reason whatsoever; (ii) the occurrence or continuance of
any Default; (iii) any adverse change in the condition (financial or otherwise)
of the Borrower; (iv) the acceleration or maturity of any Loans or the
termination of any Commitment after the making of any Swing Line Loan; (v) any
breach of this Agreement or any other Loan Document by the Borrower or any
Lender; or (vi) any other circumstance, happening or event whatsoever, whether
or not similar to any of the foregoing.

         (c) In the event that the Borrower or any other Obligor is subject to
any bankruptcy or insolvency proceedings as provided in Section 8.1.9, or if for
any other reason Revolving Loans cannot be made or are unavailable, each Lender
with a Revolving Loan Commitment shall acquire without recourse or warranty an
undivided participation interest equal to such Lender's Percentage of any Swing
Line Loan otherwise required to be repaid by such Lender pursuant to the
preceding clause by paying to the Swing Line Lender on the date on which such
Lender would otherwise have been required to make a Revolving Loan in respect of
such Swing Line Loan pursuant to the preceding clause, in same day funds, an
amount equal to such Lender's Percentage of such Swing Line Loan, and no
Revolving Loans shall be made by such Lender pursuant to the preceding clause.
From and after the date on which any Lender purchases an

                                      -42-
<PAGE>   51

undivided participation interest in a Swing Line Loan pursuant to this clause,
the Swing Line Lender shall distribute to such Lender (appropriately adjusted,
in the case of interest payments, to reflect the period of time during which
such Lender's participation interest is outstanding and funded) its ratable
amount of all payments of principal and interest in respect of such Swing Line
Loan in like funds as received; provided, however, that in the event such
payment received by the Swing Line Lender is required to be returned to the
Borrower, such Lender shall return to the Swing Line Lender the portion of any
amounts which such Lender had received from the Swing Line Lender in like funds.

         SECTION 2.4. Continuation and Conversion Elections. By delivering a
Continuation/Conversion Notice to the Administrative Agent on or before 9:00
a.m., San Francisco time, on a Business Day, the Borrower may from time to time
irrevocably elect, on not less than one Business Day's notice (in the case of a
conversion of LIBO Rate Loans to Base Rate Loans) or three Business Days' notice
(in the case of a continuation of LIBO Rate Loans or a conversion of Base Rate
Loans to LIBO Rate Loans) nor more than five Business Days' notice (in the case
of all Loans) that all, or any portion in an aggregate minimum amount of
$500,000 and an integral multiple of $100,000, of any Loans (other than Swing
Line Loans) be, in the case of Base Rate Loans, converted into LIBO Rate Loans
or, in the case of LIBO Rate Loans, be converted into a Base Rate Loan or a LIBO
Rate Loan or continued as a LIBO Rate Loan (in the absence of delivery of a
Continuation/Conversion Notice with respect to any LIBO Rate Loan at least three
Business Days before the last day of the then current Interest Period with
respect thereto, such LIBO Rate Loan shall, on such last day, automatically
convert to a Base Rate Loan); provided, however, that (i) each such conversion
or continuation shall be pro rated among the applicable outstanding Loans of all
Lenders, and (ii) no portion of the outstanding principal amount of any Loans
may be continued as, or be converted into, LIBO Rate Loans when any Default has
occurred and is continuing.

         SECTION 2.5. Funding. Each Lender may, if it so elects, fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign branches or Affiliates (or an international banking facility
created by such Lender) to make or maintain such LIBO Rate Loan; provided,
however, that such LIBO Rate Loan shall nonetheless be deemed to have been made
and to be held by such Lender, and the obligation of the Borrower to repay such
LIBO Rate Loan shall nevertheless be to such Lender for the account of such
foreign branch, Affiliate or international banking facility. In addition, the
Borrower hereby consents and agrees that, for purposes of any determination to
be made for purposes of Section 4.1, 4.2, 4.3 or 4.4, it shall be conclusively
assumed that each Lender elected to fund all LIBO Rate Loans by purchasing
Dollar deposits in its LIBOR Office's interbank eurodollar market.

         SECTION 2.6. Issuance Procedures. By delivering to the Administrative
Agent an Issuance Request on or before 9:00 a.m., San Francisco time, on a
Business Day, the Borrower may, from time to time irrevocably request, on not
less than three nor more than ten Business Days' notice (or such other notice
period as may be acceptable to the Issuer in its sole discretion), in the case
of an initial issuance of a Letter of Credit, and not less than three nor more
than ten

                                      -43-
<PAGE>   52

Business Days' notice prior to the then existing Stated Expiry Date of a Letter
of Credit (or such other notice period as may be acceptable to the Issuer in its
sole discretion), in the case of a request for the extension of the Stated
Expiry Date of a Letter of Credit, that the Issuer issue, or extend the Stated
Expiry Date of, as the case may be, an irrevocable Letter of Credit on behalf of
the Borrower (whether issued for the Borrower's account or for the account of
any Subsidiary Guarantor and whose outstanding Capital Stock is pledged to the
Administrative Agent for the benefit of the Lenders pursuant to a Pledge
Agreement), in such form as may be requested by the Borrower and approved by the
Issuer, solely for the purposes described in Section 7.1.9. Notwithstanding
anything to the contrary contained herein or in any separate application for any
Letter of Credit, the Borrower hereby acknowledges and agrees that it shall be
obligated to reimburse the Issuer upon each Disbursement of any Letter of
Credit, and it shall be deemed to be an obligor for purposes of each such Letter
of Credit issued hereunder (whether the account party on such Letter of Credit
is the Borrower or a wholly-owned U.S. Subsidiary of the Borrower). Upon receipt
of an Issuance Request, the Administrative Agent shall promptly notify the
Issuer and each Lender thereof and the Issuer shall, subject to the terms and
conditions hereof, including Article V, promptly (but in no event later than
three Business Days after such notification) issue a Letter of Credit. Each
Letter of Credit shall by its terms be stated to expire on a date (its "Stated
Expiry Date") no later than the earlier to occur of (i) the Revolving Loan
Commitment Termination Date and (ii) one year from the date of its issuance. The
Issuer will make available to the beneficiary thereof the original of each
Letter of Credit which it issues hereunder.

         SECTION 2.6.1. Other Lenders' Participation. Upon the issuance of each
Letter of Credit issued by the Issuer pursuant hereto, and without further
action, each Lender (other than the Issuer) that has a Revolving Loan Commitment
shall be deemed to have irrevocably purchased from the Issuer, to the extent of
its Percentage in respect of Revolving Loans, and the Issuer shall be deemed to
have irrevocably granted and sold to such Lender a participation interest in
such Letter of Credit (including the Contingent Liability and any Reimbursement
Obligation and all rights with respect thereto), and such Lender shall, to the
extent of its Percentage in respect of Revolving Loans, be responsible for
reimbursing promptly (and in any event within one Business Day) the Issuer for
Reimbursement Obligations which have not been reimbursed by the Borrower in
accordance with Section 2.6.3. In addition, such Lender shall, to the extent of
its Percentage in respect of Revolving Loans, be entitled to receive a ratable
portion of the Letter of Credit fees payable pursuant to Section 3.3.3 with
respect to each Letter of Credit and of interest payable pursuant to Section 3.2
with respect to any Reimbursement Obligation. To the extent that any Lender has
reimbursed the Issuer for a Disbursement as required by this Section, such
Lender shall be entitled to receive its ratable portion of any amounts
subsequently received (from the Borrower or otherwise) in respect of such
Disbursement.

         SECTION 2.6.2. Disbursements; Conversion to Revolving Loans. The Issuer
will notify the Borrower and the Administrative Agent promptly of the
presentment for payment of any Letter of Credit issued by the Issuer, together
with notice of the date (the "Disbursement Date") such payment shall be made
(each such payment, a "Disbursement"). Subject to the terms and

                                      -44-
<PAGE>   53

provisions of such Letter of Credit and this Agreement, the Issuer shall make
such payment to the beneficiary (or its designee) of such Letter of Credit.
Prior to 9:00 a.m., San Francisco time, on the first Business Day following the
Disbursement Date (the "Disbursement Due Date"), the Borrower shall be obligated
to reimburse the Administrative Agent, for the account of the Issuer, for all
amounts which the Issuer has disbursed under such Letter of Credit, together
with interest thereon at the rate per annum otherwise applicable to Revolving
Loans (made as Base Rate Loans) from and including the Disbursement Date to but
excluding the Disbursement Due Date and, thereafter (unless such Disbursement is
converted into a Base Rate Loan on the Disbursement Due Date), at a rate per
annum equal to the rate per annum then in effect with respect to overdue
Revolving Loans (made as Base Rate Loans) pursuant to Section 3.2.2 for the
period from and including the Disbursement Due Date to but excluding the date of
such reimbursement; provided, however, that, if no Default shall have then
occurred and be continuing, unless the Borrower has notified the Administrative
Agent no later than one Business Day prior to the Disbursement Due Date that it
will reimburse the Issuer for the applicable Disbursement, then the amount of
the Disbursement shall be deemed to be a Revolving Loan constituting a Base Rate
Loan and following the giving of notice thereof by the Administrative Agent to
the Lenders, each Lender with a commitment to make Revolving Loans (other than
the Issuer) will deliver to the Issuer on the Disbursement Due Date immediately
available funds in an amount equal to such Lender's Percentage of such Revolving
Loan. Each conversion of Disbursement amounts into Revolving Loans shall
constitute a representation and warranty by the Borrower that on the date of the
making of such Revolving Loan all of the statements set forth in Section 5.2.1
are true and correct.

         SECTION 2.6.3. Reimbursement. The obligation (a "Reimbursement
Obligation") of the Borrower under Section 2.6.2 to reimburse the Issuer with
respect to each Disbursement (including interest thereon) not converted into a
Base Rate Loan pursuant to Section 2.6.2, and, upon the failure of the Borrower
to reimburse the Issuer and the giving of notice thereof by the Administrative
Agent to the Lenders, each Lender's (to the extent such Lender has a Revolving
Loan Commitment) obligation under Section 2.6.1 to reimburse the Issuer or fund
its Percentage of any Disbursement converted into a Base Rate Loan, shall be
absolute and unconditional under any and all circumstances and irrespective of
any setoff, counterclaim or defense to payment which the Borrower or such
Lender, as the case may be, may have or have had against the Issuer or any such
Lender, including any defense based upon the failure of any Disbursement to
conform to the terms of the applicable Letter of Credit (if, in the Issuer's
good faith opinion, such Disbursement is determined to be appropriate) or any
non-application or misapplication by the beneficiary of the proceeds of such
Letter of Credit; provided, however, that after paying in full its Reimbursement
Obligation hereunder, nothing herein shall adversely affect the right of the
Borrower or such Lender, as the case may be, to commence any proceeding against
the Issuer for any wrongful Disbursement made by the Issuer under a Letter of
Credit as a result of acts or omissions constituting gross negligence or willful
misconduct on the part of the Issuer.

         SECTION 2.6.4. Deemed Disbursements. Upon the occurrence and during the
continuation of any Event of Default of the type described in Section 8.1.9 or,
with notice from

                                      -45-
<PAGE>   54

the Administrative Agent acting at the direction of the Required Lenders, upon
the occurrence and during the continuation of any other Event of Default,

                  (a) an amount equal to that portion of all Letter of Credit
         Outstandings attributable to the then aggregate amount which is undrawn
         and available under all Letters of Credit issued and outstanding shall,
         without demand upon or notice to the Borrower or any other Person, be
         deemed to have been paid or disbursed by the Issuer under such Letters
         of Credit (notwithstanding that such amount may not in fact have been
         so paid or disbursed); and

                  (b) upon notification by the Administrative Agent to the
         Borrower of the obligations of the Borrower under this Section, the
         Borrower shall be immediately obligated to reimburse the Issuer for the
         amount deemed to have been so paid or disbursed by the Issuer.

Any amounts so payable by the Borrower pursuant to this Section shall be
deposited in cash with the Administrative Agent and held as collateral security
for the Obligations in connection with the Letters of Credit issued by the
Issuer. At such time when the Events of Default giving rise to the deemed
disbursements hereunder shall have been cured or waived, the Administrative
Agent shall return to the Borrower all amounts then on deposit with the
Administrative Agent pursuant to this Section, together with accrued interest at
the Federal Funds Rate, which have not been applied to the satisfaction of such
Obligations.

         SECTION 2.6.5. Nature of Reimbursement Obligations. The Borrower and,
to the extent set forth in Section 2.6.1, each Lender with a Revolving Loan
Commitment, shall assume all risks of the acts, omissions or misuse of any
Letter of Credit by the beneficiary thereof. The Issuer (except to the extent of
its own gross negligence or willful misconduct) shall not be responsible for:

                  (a) the form, validity, sufficiency, accuracy, genuineness or
         legal effect of any Letter of Credit or any document submitted by any
         party in connection with the application for and issuance of a Letter
         of Credit, even if it should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged;

                  (b) the form, validity, sufficiency, accuracy, genuineness or
         legal effect of any instrument transferring or assigning or purporting
         to transfer or assign a Letter of Credit or the rights or benefits
         thereunder or the proceeds thereof in whole or in part, which may prove
         to be invalid or ineffective for any reason;

                  (c) failure of the beneficiary to comply fully with conditions
         required in order to demand payment under a Letter of Credit;

                                      -46-
<PAGE>   55

                  (d) errors, omissions, interruptions or delays in transmission
         or delivery of any messages, by mail, cable, telegraph, telex or
         otherwise; or

                  (e) any loss or delay in the transmission or otherwise of any
         document or draft required in order to make a Disbursement under a
         Letter of Credit.

None of the foregoing shall affect, impair or prevent the vesting of any of the
rights or powers granted to the Issuer or any Lender with a Revolving Loan
Commitment hereunder. In furtherance and extension and not in limitation or
derogation of any of the foregoing, any action taken or omitted to be taken by
the Issuer in good faith (and not constituting gross negligence or wilful
misconduct) shall be binding upon the Borrower, each other Obligor and each such
Lender, and shall not put the Issuer under any resulting liability to the
Borrower, any other Obligor or any such Lender, as the case may be.

         SECTION 2.7. Register; Notes. (a) Each Lender may maintain in
accordance with its usual practice an account or accounts evidencing the
Indebtedness of the Borrower to such Lender resulting from each Loan made by
such Lender, including the amounts of principal and interest payable and paid to
such Lender from time to time hereunder. In the case of a Lender that does not
request, pursuant to clause (b)(ii) below, execution and delivery of a Note
evidencing the Loans made by such Lender to the Borrower, such account or
accounts shall, to the extent not inconsistent with the notations made by the
Administrative Agent in the Register, be conclusive and binding on the Borrower
absent manifest error; provided, however, that the failure of any Lender to
maintain such account or accounts shall not limit or otherwise affect any
Obligations of the Borrower or any other Obligor.

         (b)(i) The Borrower hereby designates the Administrative Agent to serve
as the Borrower's agent, solely for the purpose of this clause (b), to maintain
a register (the "Register") on which the Administrative Agent will record each
Lender's Commitment, the Loans made by each Lender and each repayment in respect
of the principal amount of the Loans, annexed to which the Administrative Agent
shall retain a copy of each Lender Assignment Agreement delivered to the
Administrative Agent pursuant to Section 10.11.1. Failure to make any
recordation, or any error in such recordation, shall not affect any Obligor's
Obligations. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrower, the Administrative Agent and the Lenders shall
treat each Person in whose name a Loan (and as provided in clause (ii) the Note
evidencing such Loan, if any) is registered as the owner thereof for the
purposes of all Loan Documents, notwithstanding notice or any provision herein
to the contrary. A Lender's Commitment or the Loans made pursuant thereto may be
assigned or otherwise transferred in whole or in part only by registration of
such assignment or transfer in the Register. Any assignment or transfer of a
Commitment or the Loans made pursuant thereto shall be registered in the
Register only upon delivery to the Administrative Agent of a Lender Assignment
Agreement that has been executed by the requisite parties pursuant to Section
10.11.1. No assignment or transfer of a Lender's Commitment or Loans shall be
effective unless

                                      -47-
<PAGE>   56

such assignment or transfer shall have been recorded in the Register by the
Administrative Agent as provided in this Section.

         (ii) The Borrower agrees that, upon the request to the Administrative
Agent by any Lender, the Borrower will execute and deliver to such Lender a Note
evidencing the Loans made by such Lender. The Borrower hereby irrevocably
authorizes each Lender to make (or cause to be made) appropriate notations on
the grid attached to such Lender's Note (or on any continuation of such grid),
which notations, if made, shall evidence, inter alia, the date of, the
outstanding principal amount of, and the interest rate and Interest Period
applicable to the Loans evidenced thereby. Such notations shall, to the extent
not inconsistent with notations made by the Administrative Agent in the
Register, be conclusive and binding on each Obligor absent manifest error;
provided, however, that the failure of any Lender to make any such notations
shall not limit or otherwise affect any Obligations of any Obligor. The Loans
evidenced by any Registered Note and interest thereon shall at all times
(including after assignment pursuant to Section 10.11.1) be payable to the order
of the payee named therein and its registered assigns.

                                   ARTICLE III

                   REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

         SECTION 3.1. Repayments and Prepayments; Application.

         SECTION 3.1.1. Repayments and Prepayments. The Borrower shall repay in
full the unpaid principal amount of each Loan upon the Stated Maturity Date
therefor. Prior thereto, the Borrower

                  (a) may, from time to time on any Business Day, make a
         voluntary prepayment, in whole or in part, of the outstanding principal
         amount of any Loans; provided, however, that

                           (i) (x) any such prepayment of Term A Loans or Term B
                  Loans shall be made pro rata among Term A Loans or Term B
                  Loans, as applicable, of the same type and, if applicable,
                  having the same Interest Period of all Lenders that have made
                  such Term A Loans or Term B Loans and (y) any such prepayment
                  of Revolving Loans shall be made pro rata among the Revolving
                  Loans of the same type and, if applicable, having the same
                  Interest Period of all Lenders that have made such Revolving
                  Loans;

                           (ii) the Borrower shall comply with Section 4.4 in
                  the event that any LIBO Rate Loan is prepaid on any day other
                  than the last day of the Interest Period for such Loan;

                           (iii) all such voluntary prepayments of LIBO Rate
                  Loans shall require at least three but no more than five
                  Business Days' prior written notice to the Administrative
                  Agent;

                           (iv) all such voluntary prepayments of Base Rate
                  Loans shall require at least one but no more than five
                  Business Days' prior written notice to the Administrative
                  Agent; and

                           (v) all such voluntary partial prepayments shall be
                  in an aggregate minimum amount of $500,000 and an integral
                  multiple of $100,000;

                  (b) shall, no later than one Business Day following the
         receipt of any Net Disposition Proceeds or Net Debt Proceeds by the
         Borrower or any of its Subsidiaries, deliver to the Administrative
         Agent a calculation of the amount of such Net Disposition Proceeds or
         Net Debt Proceeds, as the case may be, and make a mandatory prepayment
         of the Term Loans in an amount equal to 100% of such Net Disposition
         Proceeds or Net Debt Proceeds, as the case may be, to be applied as set
         forth in Section 3.1.2; provided, however, that with respect to Net
         Disposition Proceeds in an aggregate amount not to exceed $10,000,000,
         no such prepayment shall be required under this clause if the Borrower
         informs the Agents no later than 60 days following the date of receipt
         by the Borrower or any of its Subsidiaries of such Net Disposition
         Proceeds of its or its Subsidiary's good faith intention to segregate
         and reinvest such Net Disposition Proceeds within 365 days of receipt
         by the Borrower or such Subsidiary, with the amount of such Net
         Disposition Proceeds unused after such 365 day period being applied to
         the Loans pursuant to Section 3.1.2;

                  (c) shall, no later than ten Business Days following the date
         that the annual audited financial reports related to each Fiscal Year
         occurring subsequent to December 31, 2000 are required to be delivered
         pursuant to clause (b) of Section 7.1.1, deliver to the Administrative
         Agent a calculation of the Excess Cash Flow for the prior Fiscal Year
         and, no later than five Business Days following the delivery of such
         calculation, make a mandatory prepayment of the Term Loans in an amount
         equal to 50% of an amount equal to the Excess Cash Flow for such Fiscal
         Year, to be applied as set forth in Section 3.1.2; provided, however,
         that if the Leverage Ratio is less than 2.50:1 as of the end of the
         immediately preceding Fiscal Year, no such prepayment shall be
         required;

                  (d) shall, concurrently with the receipt of any Casualty
         Proceeds by the Borrower or any of its Subsidiaries in excess of
         $1,000,000 (individually or in the aggregate over the course of a
         Fiscal Year), deposit such Casualty Proceeds in an account maintained
         with the Administrative Agent and within 60 days following the receipt
         by the Borrower or any of its Subsidiaries of such Casualty Proceeds,
         direct the Administrative Agent to apply such Casualty Proceeds to
         prepay the Term Loans in an amount equal to 100% of such Casualty
         Proceeds, to be applied as set forth in Section 3.1.2; provided that no

                                      -49-
<PAGE>   58

         mandatory prepayment on account of Casualty Proceeds shall be required
         under this clause if the Borrower informs the Agents no later than 60
         days following the date of receipt by the Borrower or any of its
         Subsidiaries of such Casualty Proceeds of its or its Subsidiary's good
         faith intention to apply such Casualty Proceeds to the rebuilding or
         replacement of the damaged, destroyed or condemned assets or property
         and in fact uses such Casualty Proceeds to rebuild or replace the
         damaged, destroyed or condemned assets or property within 365 days
         following the receipt of such Casualty Proceeds, with the amount of
         such Casualty Proceeds unused after such 365 day period being applied
         to the Loans pursuant to Section 3.1.2;

                  (e) shall, on the Stated Maturity Date and on each Quarterly
         Payment Date, make a scheduled repayment of the aggregate outstanding
         principal amount, if any, of all Term A Loans and Term B Loans in an
         amount equal to the applicable percentage of such principal amount as
         provided in the applicable table set forth in Annex I to this Agreement
         (as such principal amounts may have otherwise been reduced pursuant to
         this Agreement);

                  (f) shall, on each date when a reduction in the Revolving Loan
         Commitment Amount shall become effective pursuant to Section 2.2, make
         a mandatory prepayment of Revolving Loans and (if necessary) deposit
         with the Administrative Agent cash collateral for Letter of Credit
         Outstandings in an aggregate amount equal to the excess, if any, of the
         aggregate outstanding principal amount of all Revolving Loans and
         Letter of Credit Outstandings over the Revolving Loan Commitment Amount
         as so reduced; and

                  (g) shall, immediately upon any acceleration of the Stated
         Maturity Date of any Loans or Obligations pursuant to Section 8.2 or
         Section 8.3, repay all Loans and provide the Administrative Agent with
         cash collateral in an amount equal to the Letter of Credit
         Outstandings, unless, pursuant to Section 8.3, only a portion of all
         Loans and Obligations are so accelerated (in which case the portion so
         accelerated shall be so prepaid or cash collateralized with the
         Administrative Agent).

         SECTION 3.1.2. Application. (a) Subject to clause (b) below, each
prepayment or repayment of the principal of the Loans shall be applied, to the
extent of such prepayment or repayment, first, to the principal amount thereof
being maintained as Base Rate Loans, and second, to the principal amount thereof
being maintained as LIBO Rate Loans.

         (b) Each voluntary prepayment of Term Loans and each prepayment of Term
Loans made pursuant to clauses (b), (c) and (d) of Section 3.1.1 shall be
applied (i) first, on a pro rata basis, to the outstanding principal amount of
all Term A Loans and Term B Loans and the remaining Term A Loan or Term B Loan
amortization payments required pursuant to clause (e) of Section 3.1.1, until
all such Term A Loans and Term B Loans have been paid in full; provided,
however, that if the Borrower at any time elects in writing, in its sole
discretion, to permit any Lender that has Term B Loans to decline to have such
Term B Loans prepaid, then any Lender

                                      -50-
<PAGE>   59

having Term B Loans outstanding may, by delivering a notice to the Agents at
least one Business Day prior to the date that such prepayment is to be made,
decline to have such Term B Loans prepaid with the amounts set forth above, in
which case 100% of the amounts that would have been applied to a prepayment of
such Lender's Term B Loans shall instead be applied to a prepayment of the Term
A Loans (until paid in full); and (ii) second, once all Term A Loans and Term B
Loans have been repaid in full, all prepayments of Loans made pursuant to
clauses (b), (c) and (d) of Section 3.1.1 shall be applied to the repayment of
any outstanding Revolving Loans without a corresponding reduction of the
Revolving Loan Commitment Amount.

         SECTION 3.2. Interest Provisions. Interest on the outstanding principal
amount of Loans shall accrue and be payable in accordance with this Section 3.2.

         SECTION 3.2.1. Rates. Pursuant to an appropriately delivered Borrowing

comprising a Borrowing accrue interest at a rate per annum:

                  (a) on that portion maintained from time to time as a Base
         Rate Loan, equal to the sum of the Alternate Base Rate from time to
         time in effect plus the Applicable Margin for Base Rate Loans; and

                  (b) on that portion maintained as a LIBO Rate Loan, during
         each Interest Period applicable thereto, equal to the sum of the LIBO
         Rate (Reserve Adjusted) for such Interest Period plus the Applicable
         Margin for LIBO Rate Loans.

         SECTION 3.2.2. Post-Maturity Rates. After the date any principal amount
of any Loan is due and payable (whether on the Stated Maturity Date, upon
acceleration or otherwise), or after any other monetary Obligation of the
Borrower (other than overdue Reimbursement Obligations which shall bear interest
as provided in Section 2.6.2) shall have become due and payable, the Borrower
shall pay, but only to the extent permitted by law, interest (after as well as
before judgment) on such amounts at a rate per annum equal to the rate that
would otherwise have been applicable to Base Rate Loans plus 2%.

         SECTION 3.2.3. Payment Dates. Interest accrued on each Loan shall be
payable, without duplication:

                  (a) on the Stated Maturity Date therefor;

                  (b) on the date of any optional or required payment or
         prepayment, in whole or in part, of principal outstanding on such Loan;

                  (c) with respect to Base Rate Loans, on each Quarterly Payment
         Date occurring after the Closing Date;

                                      -51-
<PAGE>   60

                  (d) with respect to LIBO Rate Loans, on the last day of each
         applicable Interest Period (and, if such Interest Period shall exceed
         three months, on each date occurring at three month intervals after the
         first day of such Interest Period);

                  (e) with respect to any Base Rate Loans converted into LIBO
         Rate Loans on a day when interest would not otherwise have been payable
         pursuant to clause (c), on the date of such conversion; and

                  (f) on that portion of any Loans the Stated Maturity Date of
         which is accelerated pursuant to Section 8.2 or Section 8.3,
         immediately upon such acceleration.

Interest accrued on Loans, Reimbursement Obligations or other monetary
Obligations arising under this Agreement or any other Loan Document after the
date such amount is due and payable (whether on the Stated Maturity Date, upon
acceleration or otherwise) shall be payable upon demand.

         SECTION 3.3. Fees. The Borrower agrees to pay the fees set forth in
this Section 3.3. All such fees shall be non-refundable.

         SECTION 3.3.1. Commitment Fee. The Borrower agrees to pay to the
Administrative Agent for the account of each Lender that has a Revolving Loan
Commitment, for each day during the period (including any portion thereof when
any of the Lenders' Revolving Loan Commitments are suspended by reason of the
Borrower's inability to satisfy any condition of Article V) commencing on the
Closing Date and continuing through the Revolving Loan Commitment Termination
Date a commitment fee on such Lender's Percentage of the unused portion of the
Revolving Loan Commitment Amount, whether or not then available, for such day at
a rate per annum equal to the Applicable Commitment Fee for such day. Such
commitment fees shall be payable by the Borrower in arrears on each Quarterly
Payment Date, commencing with the first such day following the Closing Date, and
on the Revolving Loan Commitment Termination Date. The making of Swing Line
Loans by the Swing Line Lender shall not constitute usage under the Revolving
Loan Commitment for the purpose of calculating the commitment fees to be paid by
the Borrower to the Lenders pursuant to this Section 3.3.1.

         SECTION 3.3.2. Agents' and Lead Arranger's Fees. The Borrower agrees to
pay to

                  (a) the Syndication Agent and the Lead Arranger, for their own
         respective accounts, fees in the amounts and on the dates set forth in
         the Syndication Agent Fee Letter; and

                  (b) to pay the Administrative Agent, for its own account, an
         annual administration fee in the amounts and on the dates set forth in
         the Administrative Agent Fee Letter.

                                      -52-
<PAGE>   61

         SECTION 3.3.3. Letter of Credit Face Amount Fee. The Borrower agrees to
pay to the Administrative Agent, for the account of each Lender that has a
Revolving Loan Commitment, a fee for each Letter of Credit for the period from
and including the date of the issuance of such Letter of Credit to (but not
including) the date upon which such Letter of Credit expires, at a rate per
annum equal to the Applicable Margin for such day for Revolving Loans that are
maintained as LIBO Rate Loans, minus 1/8 of 1%. Such fee shall be payable by the
Borrower in arrears each Quarterly Payment Date, and on the Revolving Loan
Commitment Termination Date for any period then ending for which such fee shall
not theretofore have been paid, commencing on the first such date after the
issuance of such Letter of Credit.

         SECTION 3.3.4. Letter of Credit Issuing Fee. The Borrower agrees to pay
to the Administrative Agent, for the account of the Issuer, an issuing fee for
each Letter of Credit for the period from and including the date of issuance of
such Letter of Credit to (but excluding) the date upon which such Letter of
Credit expires, of .25% per annum of the face amount of such Letter of Credit.
Such fee shall be payable by the Borrower in arrears on each Quarterly Payment
Date and on the Revolving Loan Commitment Termination Date for any period then
ending for which such fee shall not theretofore have been paid, commencing on
the first such date after the issuance of such Letter of Credit.

                                   ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

         SECTION 4.1. LIBO Rate Lending Unlawful. If any Lender shall determine
(which determination shall, upon notice thereof to the Borrower and the Lenders,
be conclusive and binding on the Borrower) that the introduction of or any
change in or in the interpretation of any law makes it unlawful, or any central
bank or other governmental authority asserts that it is unlawful, for such
Lender to make, continue or maintain any Loan as, or to convert any Loan into, a
LIBO Rate Loan of a certain type, the obligations of all Lenders to make,
continue, maintain or convert into any such Loans shall, upon such
determination, forthwith be suspended until such Lender shall notify the
Administrative Agent that the circumstances causing such suspension no longer
exist, and all LIBO Rate Loans of such type shall automatically convert into
Base Rate Loans at the end of the then current Interest Periods with respect
thereto or sooner, if required by such law or assertion.

         SECTION 4.2. Deposits Unavailable. If the Administrative Agent shall
have determined that

                  (a) Dollar certificates of deposit or Dollar deposits, as the
         case may be, in the relevant amount and for the relevant Interest
         Period are not available to the Administrative Agent in its relevant
         market; or

                                      -53-
<PAGE>   62

                  (b) by reason of circumstances affecting the Administrative
         Agent's relevant market, adequate means do not exist for ascertaining
         the interest rate applicable hereunder to LIBO Rate Loans of such type,

then, upon notice from the Administrative Agent to the Borrower and the Lenders,
the obligations of all Lenders under Section 2.3 and Section 2.4 to make or
continue any Loans as, or to convert any Loans into, LIBO Rate Loans of such
type shall forthwith be suspended until the Administrative Agent shall notify
the Borrower and the Lenders that the circumstances causing such suspension no
longer exist.

         SECTION 4.3. Increased LIBO Rate Loan Costs, etc. The Borrower agrees
to reimburse each Lender for any increase in the cost to such Lender of, or any
reduction in the amount of any sum receivable by such Lender in respect of,
making, continuing or maintaining (or of its obligation to make, continue or
maintain) any Loans as, or of converting (or of its obligation to convert) any
Loans into, LIBO Rate Loans. Such Lender shall promptly notify the
Administrative Agent and the Borrower in writing of the occurrence of any such
event, such notice to state, in reasonable detail, the reasons therefor and the
additional amount required fully to compensate such Lender for such increased
cost or reduced amount. Such additional amounts shall be payable by the Borrower
directly to such Lender within five days of its receipt of such notice, and such
notice shall, in the absence of manifest error, be conclusive and binding on the
Borrower.

         SECTION 4.4. Funding Losses. In the event any Lender shall incur any
loss or expense (including any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by such Lender
to make, continue or maintain any portion of the principal amount of any Loan
as, or to convert any portion of the principal amount of any Loan into, a LIBO
Rate Loan) as a result of

                  (a) any conversion or repayment or prepayment of the principal
         amount of any LIBO Rate Loans on a date other than the scheduled last
         day of the Interest Period applicable thereto, whether pursuant to
         Section 3.1 or otherwise;

                  (b) any Loans not being made as LIBO Rate Loans in accordance
         with the Borrowing Request therefor; or

                  (c) any Loans not being continued as, or converted into, LIBO
         Rate Loans in accordance with the Continuation/Conversion Notice
         therefor,

then, upon the written notice of such Lender to the Borrower (with a copy to the
Administrative Agent), the Borrower shall, within five days of its receipt
thereof, pay directly to such Lender such amount as will (in the reasonable
determination of such Lender) reimburse such Lender for such loss or expense.
Such written notice (which shall include calculations in reasonable detail)
shall, in the absence of manifest error, be conclusive and binding on the
Borrower.

                                      -54-
<PAGE>   63

         SECTION 4.5. Increased Capital Costs. If any change in, or the
introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request
(whether or not having the force of law) of any court, central bank, regulator
or other governmental authority affects or would affect the amount of capital
required or expected to be maintained by any Lender or any Person controlling
such Lender, and such Lender determines (in its sole and absolute discretion)
that the rate of return on its or such controlling Person's capital as a
consequence of its Commitments, issuance of or participation in Letters of
Credit or the Loans made by such Lender is reduced to a level below that which
such Lender or such controlling Person could have achieved but for the
occurrence of any such circumstance, then, in any such case upon notice from
time to time by such Lender to the Borrower, the Borrower shall immediately pay
directly to such Lender additional amounts sufficient to compensate such Lender
or such controlling Person for such reduction in rate of return. A statement of
such Lender as to any such additional amount or amounts (including calculations
thereof in reasonable detail) shall, in the absence of manifest error, be
conclusive and binding on the Borrower. In determining such amount, such Lender
may use any method of averaging and attribution that it (in its sole and
absolute discretion) shall deem applicable.

         SECTION 4.6. Taxes. All payments by the Borrower 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 Lender's net
income or receipts (such non-excluded items being called "Taxes"). In the event
that any withholding or deduction from any payment to be made by the Borrower
hereunder is required in respect of any Taxes pursuant to any applicable law,
rule or regulation, then, subject to the last paragraph of this Section 4.6, the
Borrower will

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

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

                  (c) pay to the Administrative Agent for the account of the
         Lenders such additional amount or amounts as is necessary to ensure
         that the net amount actually received by each Lender will equal the
         full amount such Lender would have received had no such withholding or
         deduction been required.

Moreover, if any Taxes are directly asserted against the Administrative Agent or
any Lender with respect to any payment received by the Administrative Agent or
such Lender hereunder, the Administrative Agent or such Lender may pay such
Taxes and, subject to the last paragraph of this Section 4.6, the Borrower shall
promptly pay such additional amounts (including any

                                      -55-
<PAGE>   64

penalties, interest or expenses) 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 not such Taxes been asserted.

         If the Borrower 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 Lenders, the required receipts or other required documentary
evidence, the Borrower shall, subject to the last paragraph of this Section 4.6,
indemnify the Lenders for any incremental Taxes, interest or penalties that may
become payable by any Lender as a result of any such failure. For purposes of
this Section 4.6, a distribution hereunder by the Administrative Agent or any
Lender to or for the account of any Lender shall be deemed a payment by the
Borrower.

         Upon the request of the Borrower or the Administrative Agent, each
Lender that is organized under the laws of a jurisdiction other than the United
States shall, prior to the due date of any payments under the Notes, execute and
deliver to the Borrower and the Administrative Agent, on or about the first
scheduled payment date in each Fiscal Year, one or more (as the Borrower or the
Administrative Agent may reasonably request) (i) United States Internal Revenue
Service Form 4224 or Form 1001 or such other forms or documents (or successor
forms or documents), appropriately completed, as may be applicable to establish
the extent, if any, to which a payment to such Lender is exempt from withholding
or deduction of Taxes or (ii) in the case of any Lender that is organized under
the laws of a jurisdiction other than the United States but is not legally
entitled to deliver either an Internal Revenue Service Form 1001 or an Internal
Revenue Service Form 4224, (A) Internal Revenue Service Forms W-8 (or successor
forms), appropriately completed, and (B) a certificate of a duly authorized
officer of such Lender to the effect that such Lender is not (x) a "bank" within
the meaning of Section 881(c)(3)(A) of the Code, (y) a "10 percent shareholder"
of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or (z) a
controlled foreign corporation receiving interest from a related person within
the meaning of Section 881(c)(3)(C) of the Code.

         The Borrower shall not be obligated to gross up any payments to any
Lender or to indemnify any Lender pursuant to this Section 4.6 in respect of
United States federal withholding taxes to the extent imposed as a result of (i)
the failure of such Lender to deliver to the Borrower the form or forms and/or
certificates, as applicable to such Lender, pursuant to the penultimate
paragraph of this Section 4.6, (ii) in the case of a Lender other than a Person
that is a Lender (an "Existing Lender") on the Amendment Effective Date (as
defined below), such form or forms and/or certificates not establishing a
complete exemption from U.S. federal withholding tax, (iii) the information or
certifications made in any such form or forms and/or certificates by the Lender
being untrue or inaccurate on the date delivered in any material respect, or
(iv) the Lender designating a successor lending office at which it maintains its
Loans which has the effect of causing such Lender to become obligated for tax
payments in excess of those in effect immediately prior to such designation
(other than any such designation of a successor lending office by an Existing
Lender prior to the Amendment Effective Date); provided, however, that the
Borrower shall be obligated to gross up any payments to any such Lender and to
indemnify

                                      -56-
<PAGE>   65

any such Lender pursuant to this Section 4.6 in respect of United States federal
withholding taxes if (i) any such failure to deliver a form or forms or
certificate or the failure of such form or forms or certificate to establish a
complete exemption from U.S. federal withholding tax or inaccuracy or untruth
contained therein resulted from a change in any applicable statute, treaty,
regulation or other applicable law or any interpretation of any of the foregoing
occurring after the date hereof (or, in the case of an Assignee Lender,
occurring after the date such Assignee Lender is deemed to have become a party
hereto pursuant to Section 10.11.1), which change rendered such Lender no longer
legally entitled to deliver such form or forms or certificate or otherwise
ineligible for a complete exemption from U.S. federal withholding tax, or
rendered the information or certifications made in such form or forms or
certificate untrue or inaccurate in a material respect, (ii) the redesignation
of the Lender's lending office was made at the request of the Borrower or (iii)
the obligation to gross up payments to any such Lender or indemnify any such
Lender pursuant to this Section 4.6 is with respect to an Assignee Lender that
becomes an Assignee Lender as a result of an assignment made at the request of
the Borrower.

         SECTION 4.7. Payments, Computations, etc. Unless otherwise expressly
provided, all payments by the Borrower pursuant to this Agreement or any other
Loan Document shall be made by the Borrower to the Administrative Agent for the
pro rata account of the Lenders entitled to receive such payment. All such
payments required to be made to the Administrative Agent shall be made, without
setoff, deduction or counterclaim, not later than 9:00 a.m., San Francisco time,
on the date due, in same day or immediately available funds, to such account as
the Administrative Agent shall specify from time to time by notice to the
Borrower. Funds received after that time shall be deemed to have been received
by the Administrative Agent on the next succeeding Business Day. The
Administrative Agent shall promptly remit in same day funds to each Lender its
share, if any, of such payments received by the Administrative Agent for the
account of such Lender. All interest and fees shall be computed on the basis of
the actual number of days (including the first day but excluding the last day)
occurring during the period for which such interest or fee is payable over a
year comprised of 360 days (or, in the case of interest on a Base Rate Loan
(other than when calculated with respect to the Federal Funds Rate), 365 days
or, if appropriate, 366 days). Whenever any payment to be made shall otherwise
be due on a day which is not a Business Day, such payment shall (except as
otherwise required by clause (c) of the definition of the term "Interest Period"
with respect to LIBO Rate Loans) be made on the next succeeding Business Day and
such extension of time shall be included in computing interest and fees, if any,
in connection with such payment.

         SECTION 4.8. Sharing of Payments. If any Lender shall obtain any
payment or other recovery (whether voluntary, involuntary, by application of
setoff or otherwise) on account of any Loan (other than pursuant to the terms of
Sections 4.3, 4.4 and 4.5) or Letter of Credit in excess of its pro rata share
of payments then or therewith obtained by all Lenders, such Lender shall
purchase from the other Lenders such participations in Loans made by them and/or
Letters of Credit as shall be necessary to cause such purchasing Lender to share
the excess payment or other recovery ratably with each of them; provided,
however, that if all or any portion of the excess payment or other recovery is
thereafter recovered from such purchasing Lender, the

                                      -57-
<PAGE>   66

purchase shall be rescinded and each Lender which has sold a participation to
the purchasing Lender shall repay to the purchasing Lender the purchase price to
the ratable extent of such recovery together with an amount equal to such
selling Lender's ratable share (according to the proportion of

                  (a) the amount of such selling Lender's required repayment to
         the purchasing Lender

to

                  (b) the total amount so recovered from the purchasing Lender)

of any interest or other amount paid or payable by the purchasing Lender in
respect of the total amount so recovered. The Borrower agrees that any Lender so
purchasing a participation from another Lender pursuant to this Section may, to
the fullest extent permitted by law, exercise all its rights of payment
(including pursuant to Section 4.9) with respect to such participation as fully
as if such Lender were the direct creditor of the Borrower in the amount of such
participation. If under any applicable bankruptcy, insolvency or other similar
law, any Lender receives a secured claim in lieu of a setoff to which this
Section applies, such Lender shall, to the extent practicable, exercise its
rights in respect of such secured claim in a manner consistent with the rights
of the Lenders entitled under this Section to share in the benefits of any
recovery on such secured claim.

         SECTION 4.9. Setoff. Each Lender shall, upon the occurrence of any
Default described in clauses (a) through (d) of Section 8.1.9, or, with the
consent of the Required Lenders, upon the occurrence of any other Event of
Default, have the right to appropriate and apply to the payment of the
Obligations owing to it (whether or not then due), and (as security for such
Obligations) the Borrower hereby grants to each Lender a continuing security
interest in, any and all balances, credits, deposits, accounts or moneys of the
Borrower then or thereafter maintained with or otherwise held by such Lender;
provided, however, that any such appropriation and application shall be subject
to the provisions of Section 4.8. Each Lender agrees promptly to notify the
Borrower and the Administrative Agent after any such setoff and application made
by such Lender; provided, however, that the failure to give such notice shall
not affect the validity of such setoff and application. The rights of each
Lender under this Section are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which such
Lender may have.

         SECTION 4.10. Replacement of Lenders. Each Lender hereby severally
agrees as set forth in this Section. If any Lender (a "Subject Lender") makes
demand upon the Borrower for (or if the Borrower is otherwise required to pay)
amounts pursuant to Section 4.2, 4.3, 4.5 or 4.6, or gives notice pursuant to
Section 4.1 requiring a conversion of such Subject Lender's LIBO Rate Loans to
Base Rate Loans or suspending such Lender's obligation to make Loans as, or to
convert Loans into, LIBO Rate Loans, the Borrower may, within 90 days of receipt
by the

                                      -58-
<PAGE>   67
Borrower of such demand or notice (or the occurrence of such other event causing
the Borrower to be required to pay such compensation), as the case may be, give
notice (a "Replacement Notice") in writing to the Agents and such Subject Lender
of its intention to replace such Subject Lender with a financial institution (a
"Replacement Lender") designated in such Replacement Notice. If the Agents
shall, in the exercise of their reasonable discretion and within 30 days of
their receipt of such Replacement Notice, notify the Borrower and such Subject
Lender in writing that the designated financial institution is satisfactory to
the Agents (such consent not being required where the Replacement Lender is
already a Lender), then such Subject Lender shall, subject to the payment of any
amounts that would otherwise be due pursuant to Section 4.4 if the Borrower were
to prepay the Loans owing to such Subject Lender at the time of such assignment,
assign, in accordance with Section 10.11.1, all of its Commitments, Loans, Notes
and other rights and obligations under this Agreement and all other Loan
Documents (including, without limitation, Reimbursement Obligations) to such
designated financial institution; provided, however, that (i) such assignment
shall be without recourse, representation or warranty and shall be on terms and
conditions reasonably satisfactory to such Subject Lender and such designated
financial institution and (ii) the purchase price paid by such designated
financial institution shall be in the amount of such Subject Lender's Loans and
its Percentage of outstanding Reimbursement Obligations, together with all
accrued and unpaid interest and fees in respect thereof, plus, unless otherwise
paid by the Borrower, all other amounts (including the amounts demanded and
unreimbursed under Sections 4.2, 4.3, 4.5 and 4.6), owing to such Subject Lender
hereunder. Upon the effective date of an assignment described above, the
Borrower shall issue a replacement Note or Notes, as applicable, to such
designated financial institution or Replacement Lender, as applicable, and such
institution shall become a "Lender" for all purposes under this Agreement and
the other Loan Documents.

         SECTION 4.11. Use of Proceeds. The Borrower shall apply the proceeds of
each Borrowing in accordance with Section 7.1.9; without limiting the foregoing,
no proceeds of any Loan will be used to acquire any equity security of a class
which is registered pursuant to Section 12 of the Securities Exchange Act of
1934 or any "margin stock", as defined in F.R.S. Board Regulation U.

         SECTION 5.1.9. Supplements to Security Agreements. The Agents shall

         Agent as the secured party, or other similar instruments or documents
         suitable for filing under the Uniform Commercial Code of all
         jurisdictions as may be necessary or, in the opinion of the Agents,

         their present names and any previous names) as the debtor and which are
         filed in the jurisdictions in which filings were made pursuant to
         clause (a) above, together with copies of such financing statements
         (none of which (other than those described in clause (a), if such Form
         UCC-11 Requests or search report, as the case may be, is current enough
         to list such financing statements described in clause (a)) shall cover
         any collateral described in the Subsidiary Security Agreement).

         SECTION 5.1.10. Financial Information, etc. The Agents shall have
received, with counterparts for each Lender,

         the Borrower, giving effect to the consummation of the Transaction

its Subsidiaries, immediately after giving effect to the CTS Acquisition and the

         SECTION 5.1.16. UCC Filing Service. All Form UCC-1 Financing
Statements, Form UCC-3 Termination Statements or other similar financing or
termination statements required pursuant to the Loan Documents (collectively,
the "Filing Statements") shall have been delivered to CT Corporation System or

shall be true and correct:

                  (a) the representations and warranties set forth in Article VI
         (excluding, however, those contained in Section 6.7) and in each other
         Loan Document shall in each case be true and correct in all material
         respects with the same effect as if then made (unless stated to relate

                  governmental investigation or proceeding shall be pending or,
                  to the knowledge of the Borrower, threatened against the
                  Borrower or any of its Subsidiaries which could reasonably be
                  expected to have a Material Adverse Effect; and

                           (ii) no development shall have occurred in any labor
                  controversy, litigation, arbitration or governmental
                  investigation or proceeding disclosed pursuant to Section 6.7

         are in material violation of any law or governmental regulation or
         court order or decree.

         SECTION 5.2.2. Credit Extension Request. The Agents shall have received

Extension. Each of the delivery of a Borrowing Request or an Issuance Request
and the acceptance by the Borrower of the proceeds of the Borrowing or the
issuance of the Letter of Credit, as applicable, shall constitute a
representation and warranty by the Borrower that on the date of such Borrowing
(both

                                      -64-
<PAGE>   73

immediately before and after giving effect to such Borrowing and the application

                  (b) is duly qualified to do business and is in good standing
         as a foreign corporation in each jurisdiction where the nature of its
         business requires such qualification, except to the extent that the

         to have, a Material Adverse Effect; and

                  (c) has full power and authority and holds all requisite

Acquisition), or upon a Subsidiary of the Borrower that was previously not a
Material Subsidiary becoming a Material Subsidiary, or upon the Borrower or any
Subsidiary of the Borrower acquiring additional Capital Stock of any existing
Subsidiary, the Borrower shall notify the Agents of such event, and

                  (a) the Borrower shall promptly (but in any event within 10
         days) cause each such Subsidiary that is a U.S. Subsidiary and a
         Material Subsidiary to execute and deliver to the Agents, with
         counterparts for each Lender, a supplement to the Subsidiary Guaranty
         and a supplement to the Subsidiary Security Agreement (and, if such
         Material Subsidiary owns or leases any real property with a fair market
         value in excess of $5,000,000 a Mortgage, to be delivered within 60
         days), together with acknowledgment copies of all Form UCC-1s executed
         and delivered by such Material Subsidiary naming it as the debtor and
         the Administrative Agent as the secured party, or other similar
         instruments or documents, filed under the UCC and any other applicable
         recording statutes, in the case of real property, of all jurisdictions
         as may be necessary or, in the reasonable opinion of the Agents,
         desirable to perfect the security interest of the Administrative Agent
         pursuant to the Subsidiary Security Agreement or a Mortgage, as the
         case may be; and

                  (b) the Borrower shall promptly deliver, or cause to be
         delivered, to the Administrative Agent under a Pledge Agreement (or a
         supplement thereto) certificates (if any) representing all of the
         issued and outstanding shares of Capital Stock of any such Subsidiary
         that is a Material Subsidiary owned by the Borrower or any U.S.
         Subsidiary of the Borrower, as the case may be, along with undated
         stock powers for such certificates, executed in blank, or, if any
         securities subject thereto are uncertificated securities, confirmation
         and evidence satisfactory to the Agents that appropriate book entries
         have been made in the relevant books or records of a financial
         intermediary or the issuer of such securities, as the case may be, or
         other appropriate steps shall have been taken under applicable law
         resulting in the perfection of the security interest granted in favor
         of the Administrative Agent pursuant to the terms of a Pledge
         Agreement;

together, in each case, with such opinions, in form and substance and from
counsel reasonably satisfactory to the Agents, as the Agents may reasonably
require; provided, however, that notwithstanding the foregoing, no Non-U.S.
Subsidiary shall be required to execute and deliver a Mortgage, a supplement to
the Subsidiary Guaranty or a supplement to the Security Agreement, nor will the
Borrower or any U.S. Subsidiary of the Borrower be required to deliver a pledge
pursuant to a Pledge Agreement or a supplement thereto in excess of 65% of the
outstanding voting stock of any Non-U.S. Subsidiary to the extent any such
pledge could be reasonably

                                      -74-

expected to result in an increase in the amount of United States federal income
tax attributable to the operations of the Borrower and its Subsidiaries arising
from the operation of Section 956 of the Code.

         SECTION 7.1.8. Future Leased Property and Future Acquisitions of Real
Property; Future Acquisition of Other Property. (a) Prior to entering into any
new lease of real property or renewing any existing lease of real property
following the Closing Date, the Borrower shall, and shall cause each of its U.S.
Subsidiaries to, use its best efforts (which shall not require the expenditure
of cash or the making of any material concessions under the relevant lease) to
deliver to the Administrative Agent a Waiver executed by the lessor of any real
property that is to be leased by the Borrower or such U.S. Subsidiary for a term
in excess of one year in any state which by statute grants such lessor a
"landlord's" (or similar) Lien which is superior to the Administrative Agent's,
to the extent the value of any personal property of the Borrower or its U.S.
Subsidiaries to be held at such leased property exceeds (or it is anticipated
that the value of such personal property will, at any point in time during the
term of such leasehold term, exceed) $5,000,000.

         (b) In the event that the Borrower or any of its U.S. Subsidiaries
shall acquire or lease any real property having a value as determined in good
faith by the Administrative Agent in excess of $5,000,000 in the aggregate, the
Borrower or the applicable U.S. Subsidiary shall, promptly (but in any event
within 60 days) after such acquisition, execute a Mortgage and provide the
Agents with

                  (i) evidence of the completion (or satisfactory arrangements
         for the completion) of all recordings and filings of such Mortgage as
         may be necessary or, in the reasonable opinion of the Agents, desirable
         effectively to create a valid, perfected first priority Lien, subject
         to Liens permitted by Section 7.2.3, against the properties purported
         to be covered thereby;

                  (ii) mortgagee's title insurance policies in favor of the
         Administrative Agent and the Lenders in amounts and in form and
         substance and issued by insurers, reasonably satisfactory to the
         Agents, with respect to the property purported to be covered by such
         Mortgage, insuring that title to such property is marketable and that
         the interests created by the Mortgage constitute valid first Liens
         thereon free and clear of all defects and encumbrances other than as
         permitted under Section 7.2.3 or as approved by the Agents, and such
         policies shall also include a revolving credit endorsement and such
         other endorsements as the Agents shall request and shall be accompanied
         by evidence of the payment in full of all premiums thereon; and

                  (iii) such other approvals, opinions, or documents as the
         Agents may reasonably request; and

         (c) In accordance with the terms and provisions of this Agreement and
the other Loan Documents, provide (within 60 days) the Agents with evidence of
all recordings and filings as

                                      -75-
<PAGE>   84

may be necessary or, in the reasonable opinion of the Agents, desirable to
create a valid, perfected first priority Lien, subject to the Liens permitted by
Section 7.2.3, against all property acquired after the Closing Date (excluding
any such recording or filing relating to any motor vehicles (other than any such
recording or filing requested when an Event of Default has occurred and is
continuing)).

         SECTION 7.1.9. Use of Proceeds, etc. The Borrower shall apply the
proceeds of the Loans

                  (a) to make certain payments in connection with the CTS
         Acquisition, concurrently with the initial Credit Extension made on the
         Amendment Effective Date, of all Indebtedness identified in Item
         7.2.2(b) of the Disclosure Schedule;

                  (b) for Capital Expenditures, and general corporate purposes
         (including Investments permitted pursuant to clauses (e), (h) and (i)
         of Section 7.2.5) and working capital purposes of the Borrower and its
         Subsidiaries;

                  (c) to make acquisitions permitted under the Loan Documents
         and to pay the related reasonable transaction costs and expenses; and

                  (d) to consummate the CTS Acquisition and pay related
         reasonable transaction costs and expenses.

         SECTION 7.1.10. Mortgages, etc. Within 90 days of the Amendment
Effective Date, the Borrower shall deliver to the Agents counterparts of each
Mortgage relating to each property with a fair market value greater than
$5,000,000 as listed on Item 6.9 ("Real Property") of the Disclosure Schedule,
duly executed by the Borrower or its applicable U.S. Subsidiary and the
Administrative Agent (or its designee), together with

                  (a) evidence of the completion (or satisfactory arrangements
         for the completion) of all recordings and filings of such Mortgage as
         may be necessary or, in the reasonable opinion of the Agents, desirable
         effectively to create a valid, perfected first priority Lien against
         the properties listed on Item 6.9 of the Disclosure Schedule, each
         dated as of the date of such delivery, purported to be covered thereby;

                  (b) the Borrower or such Subsidiary shall use its best efforts
         to obtain and deliver to the Administrative Agent estoppel letters or
         Waivers executed by the lessor of such properties, if applicable; and

                  (c) such other approvals, opinions, or documents as the Agents
         may reasonably request.

                                   THE AGENTS

         SECTION 9.1. Actions. Each Lender hereby irrevocably appoints CSFB as
its Syndication Agent and Wells Fargo as its Administrative Agent under and for
purposes of this Agreement and each other Loan Document. Each Lender authorizes
the Agents to act on behalf of such Lender under this Agreement and each other
Loan Document and, in the absence of other written instructions from the
Required Lenders received from time to time by the Agents (with respect to which
each Agent agrees that it will comply, except as otherwise provided in this
Section or as otherwise advised by counsel), to exercise such powers hereunder
and thereunder as are specifically delegated to or required of the Agents by the
terms hereof and thereof, together with such powers as may be reasonably
incidental thereto. Each Lender hereby indemnifies (which indemnity shall
survive any termination of this Agreement) the Agents, pro rata according to
such Lender's Percentage, from and against any and all liabilities, obligations,
losses, damages, claims, costs or expenses of any kind or nature whatsoever
which may at any time be imposed on, incurred by, or asserted against, any of
the Agents in any way relating to or arising out of this Agreement and any other
Loan Document, including reasonable attorneys' fees, and as to which any Agent
is not reimbursed by the Borrower, regardless of whether caused in whole or in
part by the negligence of any Agent; provided, however, that no Lender shall be
liable for the payment of any portion of such liabilities, obligations, losses,
damages, claims, costs or expenses

                                      -88-
<PAGE>   97

which are determined by a court of competent jurisdiction in a final proceeding
to have resulted solely from such Agent's gross negligence or wilful misconduct.
The Agents shall not be required to take any action hereunder, under any other
Loan Document, or to prosecute or defend any suit in respect of this Agreement
or any other Loan Document, unless they are indemnified hereunder to their
satisfaction. If any indemnity in favor of any Agent shall be or become, in such
Agent's determination, inadequate, such Agent may call for additional
indemnification from the Lenders and cease to do the acts indemnified against
hereunder until such additional indemnity is given.

         SECTION 9.2. Funding Reliance, etc. Unless the Administrative Agent
shall have been notified by telephone, confirmed in writing, by any Lender by
2:00 p.m., San Francisco time, on the day prior to a Borrowing or disbursement
with respect to a Letter of Credit pursuant to Section 2.6.2 that such Lender
will not make available the amount which would constitute its Percentage of such
Borrowing on the date specified therefor, the Administrative Agent may assume
that such Lender has made such amount available to the Administrative Agent and,
in reliance upon such assumption, make available to the Borrower a corresponding
amount. If and to the extent that such Lender shall not have made such amount
available to the Administrative Agent, such Lender and the Borrower severally
agree to repay the Administrative Agent forthwith on demand such corresponding
amount together with interest thereon, for each day from the date the
Administrative Agent made such amount available to the Borrower to the date such
amount is repaid to the Administrative Agent, at the interest rate applicable at
the time to Loans comprising such Borrowing. The Administrative Agent shall be
entitled to rely upon any certification, notice or other communication
(including any thereof by telephone, telecopier, telex, telegram or cable)
believed by it to be genuine and correct and to have been signed or sent by or
on behalf of the proper Person or Persons, and upon advice and statements of
legal counsel (which may be counsel for Borrower), independent accountants and
other experts selected by the Administrative Agent. The Administrative Agent
shall not be required in any way to determine the identity or authority of any
Person delivering or executing the same. As to any matters not expressly
provided for by this Agreement or any other Loan Document, the Administrative
Agent shall in all cases be fully protected in acting, or in refraining from
acting, hereunder and thereunder in accordance with instructions of the Required
Lenders, and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders. Pursuant to instructions of the Required Lenders,
the Administrative Agent shall have the authority to execute releases of the
applicable Loan Documents on behalf of the Lenders without the joinder of any
Lender. If any order, writ, judgment or decree shall be made or entered by any
court affecting the rights, duties and obligations of the Administrative Agent
under this Agreement or any other Loan Document, then and in any of such events
the Administrative Agent is authorized, in its sole discretion, to rely upon and
comply with such order, writ, judgment or decree which it is advised by legal
counsel of its own choosing is binding upon it under the terms of this
Agreement, the relevant Loan Document or otherwise; and if the Administrative
Agent complies with any such order, writ, judgment or decree, then it shall not
be liable to any Lender or to any other Person by reason of such compliance even
though such order, writ, judgment or decree may be subsequently reversed,
modified, annulled, set aside or vacated.

         SECTION 9.3. Exculpation. No Agent shall be bound by or obliged to
recognize any agreement among or between the Borrower and any Lender to which
such Agent is not a party, regardless of whether such Agent has knowledge of the
existence of any such agreement or the terms and provisions thereof; nor shall
the Agents be responsible for any delay, error, omission or default of any mail,
telegraph, cable or wireless agency or operator; nor shall the Agents be
responsible for the acts of any governmental authority. None of the Agents nor
any of their directors, officers, employees or agents shall be liable to any
Lender for any action taken or omitted to be taken by it under this Agreement or
any other Loan Document, or in connection herewith or therewith, except for its
own wilful misconduct or gross negligence, nor responsible for any recitals or
warranties herein or therein, nor for the effectiveness, enforceability,
validity or due execution of this Agreement or any other Loan Document, nor for
the creation, perfection or priority of any Liens purported to be created by any
of the Loan Documents, or the validity, genuineness, enforceability, existence,
value or sufficiency of any collateral security, nor to make any inquiry
respecting the performance by the Borrower of its obligations hereunder or under
any other Loan Document. Any such inquiry which may be made by any Agent shall
not obligate it to make any further inquiry or to take any action. The Agents
shall be entitled to rely upon advice of counsel concerning legal matters and
upon any notice, consent, certificate, statement or writing which the Agents
believe to be genuine and to have been presented by a proper Person.

         SECTION 9.4. Successor. The Syndication Agent may resign upon one
Business Day's notice to the Borrower and the Administrative Agent. The
Administrative Agent may resign as such at any time upon at least 30 days' prior
notice to the Borrower and all Lenders. If the Administrative Agent at any time
shall resign, the Required Lenders may appoint another Lender as a successor
Administrative Agent which shall thereupon become the Administrative Agent
hereunder. If no successor Administrative Agent shall have been so appointed by
the Required Lenders, and shall have accepted such appointment, within 30 days
after the retiring Administrative Agent's giving notice of resignation, then the
retiring Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be one of the Lenders or a commercial banking
institution organized under the laws of the U.S. (or any State thereof) or a
U.S. branch or agency of a commercial banking institution, and having a combined
capital and surplus of at least $500,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall be entitled to receive from the
retiring Administrative Agent such documents of transfer and assignment as such
successor Administrative Agent may reasonably request, and shall thereupon
succeed to and become vested with all rights, powers, privileges and duties of
the retiring Administrative Agent, and the retiring Administrative Agent shall
be discharged from its duties and obligations under this Agreement. After any
retiring Administrative Agent's resignation hereunder as the Administrative
Agent, the provisions of

                  (a) this Article IX shall inure to its benefit as to any
         actions taken or omitted to be taken by it while it was the
         Administrative Agent under this Agreement; and

                  (b) Section 10.3 and Section 10.4 shall continue to inure to
         its benefit.

         SECTION 9.5. Loans or Letters of Credit Issued by the Issuer. Each
Agent shall have the same rights and powers with respect to (x) the Loans made
by it or any of its Affiliates, (y) the Notes held by it or any of its
Affiliates, and (z) its participating interests in the Letters of Credit as any
other Lender and may exercise the same as if it were not the Administrative
Agent or the Syndication Agent, as the case may be. Each Agent and its
Affiliates may accept deposits from, lend money to, and generally engage in any
kind of business with the Borrower or any Subsidiary or Affiliate of the
Borrower as if such Agent were not an Agent hereunder.

         SECTION 9.6. Credit Decisions. Each Lender acknowledges that it has,
independently of the Agents, the Lead Arranger and each other Lender, and based
on such Lender's review of the financial information of the Borrower, this
Agreement, the other Loan Documents (the terms and provisions of which being
satisfactory to such Lender) and such other documents, information and
investigations as such Lender has deemed appropriate, made its own credit
decision to extend its Commitments. Each Lender also acknowledges that it will,
independently of the Agents, the Lead Arranger and each other Lender, and based
on such other documents, information and investigations as it shall deem
appropriate at any time, continue to make its own credit decisions as to
exercising or not exercising from time to time any rights and privileges
available to it under this Agreement or any other Loan Document.

         SECTION 9.7. Copies, etc. The Administrative Agent shall give prompt
notice to each Lender of each written notice or request required or permitted to
be given to the Administrative Agent by the Borrower pursuant to the terms of
this Agreement (unless concurrently delivered to the Lenders by the Borrower).
The Administrative Agent will distribute to each Lender each document or
instrument received for its account and copies of all other communications
received by the Administrative Agent from the Borrower for distribution to the
Lenders by the Administrative Agent in accordance with the terms of this
Agreement. The Administrative Agent shall not be deemed to have knowledge of the
occurrence of an Event of Default (other than the non-payment of principal of or
interest on Loans) unless the Administrative Agent has received notice from a
Lender or the Borrower specifying such Event of Default and stating that such
notice is a "notice of Default." In the event the Administrative Agent receives
such a notice of Default, the Administrative Agent shall give prompt notice
thereof to the Lenders (and shall give each Lender prompt notice of each such
non-payment).

         SECTION 9.8. Documentation Agent. The Person identified on the
signature pages of this Agreement as the "Documentation Agent" shall not have
any right, power, obligation, liability, responsibility or duty under this
Agreement (or any other Loan Document) other than those applicable to it in its
capacity as a Lender to the extent it is a Lender hereunder. Without limiting
the foregoing, the Lender so identified as the "Documentation Agent" shall not
have or be deemed to have any fiduciary relationship with any Lender. Each
Person acknowledges that it has not relied, and will not rely, on the Person so
identified as the "Documentation Agent" in deciding to enter into this Agreement
and each other Loan Document to which it is a party or in taking or not taking
action hereunder or thereunder.

                            MISCELLANEOUS PROVISIONS

         SECTION 10.1. Waivers, Amendments, etc. The provisions of this
Agreement and of each other Loan Document may from time to time be amended,
modified or waived, if such amendment, modification or waiver is in writing and
consented to by the Borrower and the Required Lenders; provided, however, that
no such amendment, modification or waiver which would:

                  (a) modify any requirement hereunder that any particular
         action be taken by all the Lenders or by the Required Lenders shall be
         effective unless consented to by each Lender;

                  (b) modify this Section 10.1 or clause (a) of Section 10.10,
         change the definition of "Required Lenders", increase any Commitment
         Amount or the Percentage of any Lender (other than pursuant to Section
         2.2.2), reduce any fees described in Article III, release any
         Subsidiary Guarantor from its obligations under the Subsidiary Guaranty
         (except pursuant to a disposition of such Subsidiary Guarantor in
         accordance with clause (b) of Section 7.2.9) or release all or
         substantially all of the collateral security (except as otherwise
         specifically provided in any Loan Document) or extend any Commitment
         Termination Date, shall be made without the consent of each Lender
         adversely affected thereby and each holder of a Note adversely affected
         thereby;

                  (c) extend the due date for, or reduce the amount of, any
         scheduled repayment of principal of or interest on or fees payable in
         respect of any Loan or any Reimbursement Obligations shall be made
         without the consent of the holder of that Note evidencing such Loan or,
         in the case of a Reimbursement Obligation, the Issuer owed, and those
         Lenders participating in, such Reimbursement Obligation;

                  (d) affect adversely the interests, rights or obligations of
         any Agent, Issuer or the Lead Arranger (in its capacity as Agent,
         Issuer or the Lead Arranger), unless consented to by such Agent, Issuer
         or the Lead Arranger, as the case may be; or

                  (e) amend, modify or waive the provisions of clause (a)(i) of
         Section 3.1.1 or clause (b) of Section 3.1.2 or effect any amendment,
         modification or waiver that by its terms adversely affects the rights
         of Lenders participating in any Tranche differently from those of
         Lenders participating in other Tranches, without the consent of the
         holders of the Notes evidencing at least 51% of the aggregate amount of
         Loans outstanding under the Tranche or Tranches affected by such
         modification, or, in the case of a modification affecting the Revolving
         Loan Commitment Amount, the Additional Term A Loan Commitment Amount or
         the Additional Term B Loan Commitment Amount, the Lenders holding at
         least 51% of the Revolving Loan Commitments, the Additional Term A Loan
         Commitments or the Additional Term B Loan Commitments, as applicable.

                                      -92-
<PAGE>   101

No failure or delay on the part of any Agent, the Issuer, any Lender or the
holder of any Note in exercising any power or right under this Agreement or any
other Loan Document shall operate as a waiver thereof, nor shall any single or
partial exercise of any such power or right preclude any other or further
exercise thereof or the exercise of any other power or right. No notice to or
demand on the Borrower in any case shall entitle it to any notice or demand in
similar or other circumstances. No waiver or approval by any Agent, the Issuer,
any Lender or the holder of any Note under this Agreement or any other Loan
Document shall, except as may be otherwise stated in such waiver or approval, be
applicable to subsequent transactions. No waiver or approval hereunder shall
require any similar or dissimilar waiver or approval thereafter to be granted
hereunder.

         For purposes of this Section 10.1, the Syndication Agent, in
coordination with the Administrative Agent, shall have primary responsibility,
together with the Borrower, in the negotiation, preparation, and documentation
relating to any amendment, modification or waiver of this Agreement, any other
Loan Document or any other agreement or document related hereto or thereto
contemplated pursuant to this Section.

         SECTION 10.2. Notices. All notices and other communications provided to
any party under this Agreement or any other Loan Document shall be in writing or
by facsimile and addressed, delivered or transmitted to such party (a) in the
case of any Lender, to the Lender in care of the Administrative Agent at its
address or facsimile number set forth on Schedule II hereto, (b) in the case of
any Agent, at its address or facsimile number set forth on Schedule II hereto,
and (c) in the case of Borrower, at its address or facsimile number set forth on
Schedule II hereto, or, in any case, at such address or facsimile number as may
be designated by such party in a notice to the other parties. Any notice, if
mailed and properly addressed with postage prepaid or if properly addressed and
sent by pre-paid courier service, shall be deemed given when received; any
notice, if transmitted by facsimile, shall be deemed given when transmitted
(receipt acknowledged).

         SECTION 10.3. Payment of Costs and Expenses. The Borrower agrees to pay
on demand all expenses of each of the Agents and the Lead Arranger (including
the reasonable fees and out-of-pocket expenses of counsel to the Agents and of
local counsel, if any, who may be retained by counsel to the Agents) in
connection with

                  (a) the syndication by the Syndication Agent and the Lead
         Arranger of the Loans, the negotiation, preparation, execution and
         delivery of this Agreement and of each other Loan Document, including
         schedules and exhibits, and any amendments, waivers, consents,
         supplements or other modifications to this Agreement or any other Loan
         Document as may from time to time hereafter be required, whether or not
         the transactions contemplated hereby are consummated;

                  (b) the filing, recording, refiling or rerecording of each
         Mortgage, each Pledge Agreement and each Security Agreement and/or any
         UCC financing statements relating thereto and all amendments,
         supplements and modifications to any thereof and any and all

                                      -93-
<PAGE>   102

         other documents or instruments of further assurance required to be
         filed or recorded or refiled or rerecorded by the terms hereof or of
         such Mortgage, Pledge Agreement or Security Agreement; and

                  (c) the preparation and review of the form of any document or
         instrument relevant to this Agreement or any other Loan Document.

The Borrower further agrees to pay, and to save the Agents, the Issuer and the
Lenders harmless from all liability for, any stamp or other taxes which may be
payable in connection with the execution or delivery of this Agreement, the
borrowings hereunder, the issuance of the Notes, the issuance of the Letters of
Credit, or any other Loan Documents. The Borrower also agrees to reimburse the
Agents, the Issuer and each Lender upon demand for all reasonable out-of-pocket
expenses (including attorneys' fees and legal expenses) incurred by such Agent,
the Issuer or such Lender in connection with (x) the negotiation of any
restructuring or "work-out", whether or not consummated, of any Obligations and
(y) the enforcement of any Obligations.

         SECTION 10.4. Indemnification. In consideration of the execution and
delivery of this Agreement by each Lender and the extension of the Commitments,
the Borrower hereby indemnifies, exonerates and holds each Agent, the Issuer,
the Lead Arranger and each Lender and each of their respective officers,
directors, partners, trustees, employees and agents (collectively, the
"Indemnified Parties") free and harmless from and against any and all actions,
causes of action, suits, losses, costs, liabilities and damages, and expenses
incurred in connection therewith (irrespective of whether any such Indemnified
Party is a party to the action for which indemnification hereunder is sought),
including reasonable attorneys' fees and disbursements (collectively, the
"Indemnified Liabilities"), incurred by the Indemnified Parties or any of them
as a result of, or arising out of, or relating to

                  (a) any transaction financed or to be financed in whole or in
         part, directly or indirectly, with the proceeds of any Loan or the use
         of any Letter of Credit;

                  (b) the entering into and performance of this Agreement and
         any other Loan Document by any of the Indemnified Parties (including
         any action brought by or on behalf of the Borrower as the result of any
         determination by the Required Lenders pursuant to Article V not to make
         any Credit Extension);

                  (c) any investigation, litigation or proceeding related to any
         acquisition or proposed acquisition by the Borrower or any of its
         Subsidiaries of all or any portion of the stock or assets of any
         Person, whether or not the Administrative Agent or such Lender is party
         thereto;

                  (d) any investigation, litigation or proceeding related to any
         environmental cleanup, audit, compliance or other matter relating to
         the protection of the environment or the Release by the Borrower or any
         of its Subsidiaries of any Hazardous Material; or

                                      -94-
<PAGE>   103

                  (e) the presence on or under, or the escape, seepage, leakage,
         spillage, discharge, emission, discharging or releases from, any real
         property owned or operated by the Borrower or any Subsidiary thereof of
         any Hazardous Material (including any losses, liabilities, damages,
         injuries, costs, expenses or claims asserted or arising under any
         Environmental Law), regardless of whether caused by, or within the
         control of, the Borrower or such Subsidiary,

except for any such Indemnified Liabilities arising for the account of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or wilful misconduct. Each Obligor and its permitted successors and
assigns hereby waive, release and agree not to make any claim, or bring any cost
recovery action against, any Agent, the Lead Arranger or any Lender under CERCLA
or any state equivalent, or any similar law now existing or hereafter enacted,
except to the extent arising out of the gross negligence or wilful misconduct of
any Indemnified Party. It is expressly understood and agreed that to the extent
that any of such Persons is strictly liable under any Environmental Laws, such
Obligor's obligation to such Person under this indemnity shall likewise be
without regard to fault on the part of such Obligor, to the extent permitted
under applicable law, with respect to the violation or condition which results
in liability of such Person. If and to the extent that the foregoing undertaking
may be unenforceable for any reason, the Borrower hereby agrees to make the
maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities which is permissible under applicable law.

         SECTION 10.5. Survival. The obligations of the Borrower under Sections
4.3, 4.4, 4.5, 4.6, 10.3 and 10.4, and the obligations of the Lenders under
Sections 4.8 and 9.1, shall in each case survive any termination of this
Agreement, the payment in full of all Obligations and the termination of all
Commitments. The representations and warranties made by each Obligor in this
Agreement and in each other Loan Document shall survive the execution and
delivery of this Agreement and each such other Loan Document.

         SECTION 10.6. Severability. Any provision of this Agreement or any
other Loan Document which is prohibited or unenforceable in any jurisdiction
shall, as to such provision and such jurisdiction, be ineffective to the extent
of such prohibition or unenforceability without invalidating the remaining
provisions of this Agreement or such Loan Document or affecting the validity or
enforceability of such provision in any other jurisdiction.

         SECTION 10.7. Headings. The various headings of this Agreement and of
each other Loan Document are inserted for convenience only and shall not affect
the meaning or interpretation of this Agreement or such other Loan Document or
any provisions hereof or thereof.

         SECTION 10.8. Execution in Counterparts, Effectiveness, etc. This
Agreement may be executed by the parties hereto in several counterparts, each of
which shall be deemed to be an original and all of which shall constitute
together but one and the same agreement. This Agreement shall become effective
when counterparts hereof executed on behalf of the Borrower and each Lender (or
notice thereof satisfactory to the Administrative Agent) shall have been

                                      -95-
<PAGE>   104

received by the Agents and notice thereof shall have been given by the
Administrative Agent to the Borrower and each Lender.

         SECTION 10.9. Governing Law; Entire Agreement. THIS AGREEMENT AND EACH
OTHER LOAN DOCUMENT SHALL EACH BE DEEMED TO BE A CONTRACT MADE UNDER AND
GOVERNED BY THE INTERNAL LAWS OF THE STATE OF NEW YORK. Subject to Section
10.5(a), this Agreement and the other Loan Documents constitute the entire
understanding among the parties hereto with respect to the subject matter hereof
and supersede any prior agreements, written or oral, with respect thereto.

         SECTION 10.10. Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that:

                  (a) the Borrower may not assign or transfer its rights or
         obligations hereunder without the prior written consent of each of the
         Agents and all Lenders; and

                  (b) the rights of sale, assignment and transfer of the Lenders
         are subject to Section 10.11.

         SECTION 10.11. Sale and Transfer of Loans and Notes; Participations in
Loans and Notes. Each Lender may assign, or sell participations in, its Loans
and Commitments to one or more other Persons in accordance with this Section
10.11.

         SECTION 10.11.1. Assignments. Any Lender,

                  (a) with the written consents of the Borrower, the Agents and
         (in the case of any assignment of participations in Letters of Credit
         or Revolving Loan Commitments) the Issuer and the Swing Line Lender
         (which consents shall not be unreasonably delayed or withheld and which
         consents of (i) the Agents, the Issuer and the Swing Line Lender shall
         not be required in the case of assignments to or by CSFB or any of its
         Affiliates (other than DLJ Merchant Banking Partners II, L.P. and/or
         its Affiliates) and (ii) the Borrower shall not be required if an Event
         of Default shall have occurred and be continuing) may at any time
         assign and delegate to one or more commercial banks, funds which are
         regularly engaged in making, purchasing or investing in loans or
         securities or other financial institutions, and

                  (b) with notice to the Borrower, the Agents and (in the case
         of any assignment of participations in Letters of Credit or Revolving
         Loan Commitments) the Issuer, but without the consent of the Borrower,
         the Agents, the Issuer or the Swing Line Lender, may assign and
         delegate to any of its Affiliates, to any other Lender or to an
         Approved Fund of any Lender

                                      -96-
<PAGE>   105

(each Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred to
as an "Assignee Lender"), all or any fraction of such Lender's total Loans,
participations in Letters of Credit and Letter of Credit Outstandings with
respect thereto and Commitments (which assignment and delegation shall be, as
among Revolving Loan Commitments, Revolving Loans and participations in Letters
of Credit, of a constant, and not a varying, percentage) in a minimum aggregate
amount of $5,000,000 in the case of any assignment relating to a Revolving Loan
Commitment and $1,000,000 in the case of any assignment relating to any Term
Loan; provided, however, that any such Assignee Lender will comply, if
applicable, with the provisions contained in the penultimate paragraph of
Section 4.6 and provided, further, however, that the Borrower, each other
Obligor and the Agents shall be entitled to continue to deal solely and directly
with such Lender in connection with the interests so assigned and delegated to
an Assignee Lender until

                  (c) written notice of such assignment and delegation, together
         with payment instructions, addresses and related information with
         respect to such Assignee Lender, shall have been given to the Borrower
         and the Agents by such Lender and such Assignee Lender,

                  (d) such Assignee Lender shall have executed and delivered to
         the Borrower and the Agents a Lender Assignment Agreement, accepted by
         the Agents,

                  (e) the processing fees described below shall have been paid,
         and

                  (f) the Administrative Agent shall have registered such
         assignment and delegation in the Register pursuant to clause (b) of
         Section 2.7.

From and after the date that the Agents accept such Lender Assignment Agreement
and such assignment is recorded in the Register pursuant to clause (b) of
Section 2.7 (x) the Assignee Lender thereunder 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 Lender in connection
with such Lender Assignment Agreement, shall have the rights and obligations of
a Lender hereunder and under the other Loan Documents, and (y) the assignor
Lender, to the extent that rights and obligations hereunder have been assigned
and delegated by it in connection with such Lender Assignment Agreement, shall
be released from its obligations hereunder and under the other Loan Documents.
Within five Business Days after its receipt of notice that the Administrative
Agent has received and accepted an executed Lender Assignment Agreement (and if
requested by the Assignee Lender), but subject to clause (c), the Borrower shall
execute and deliver to the Administrative Agent (for delivery to the relevant
Assignee Lender) a new Note (if requested by such Assignee Lender pursuant to
Section 2.7(b)(ii)) evidencing such Assignee Lender's assigned Loans and
Commitments and, if the assignor Lender has retained Loans and Commitments
hereunder (and if requested by such Lender), a replacement Note in the principal
amount of the Loans and Commitments retained by the assignor Lender hereunder
(such Note to be in exchange for, but not in payment of, any Note then held by
such assignor Lender). Each such Note shall be dated the date of the predecessor
Notes. The assignor Lender

                                      -97-
<PAGE>   106
shall mark the predecessor Notes "exchanged" and deliver them to the Borrower.
Accrued interest on that part of the predecessor Notes evidenced by the new
Notes, and accrued fees, shall be paid as provided in the Lender Assignment
Agreement. Accrued interest on that part of the predecessor Notes evidenced by
the replacement Notes shall be paid to the assignor Lender. Accrued interest and
accrued fees shall be paid at the same time or times provided in the predecessor
Notes and in this Agreement. Such assignor Lender or such Assignee Lender
(excluding any Agent) must also pay a processing fee to the Administrative Agent
upon delivery of any Lender Assignment Agreement in the amount of $1,500. Any
attempted assignment and delegation not made in accordance with this Section
10.11.1 shall be null and void.

         Nothing contained in this Section 10.11.1 shall prevent or prohibit any
Lender from pledging its rights (but not its obligations to make Loans or
participate in Letters of Credit or Letter of Credit Outstandings) under this
Agreement and/or its Loans and/or its Notes hereunder (i) to a Federal Reserve
Bank in support of borrowings made by such Lender from such Federal Reserve
Bank, or (ii) in the case of a Lender that is an investment fund, to its trustee
in support of its obligations to its trustee, in either case without notice to
or consent of the Borrower or the Agents; provided, however, that (A) such
Lender shall remain a "Lender" under this Agreement and shall continue to be
bound by the terms and conditions set forth in this Agreement and the other Loan
Documents, and (B) any assignment by such trustee shall be subject to the
provisions of this Section 10.11.1. No such pledge by any Lender shall be
required to comply with the provisions of this Section 10.11.1, and no such
pledge shall be null and void by reason of the failure to so comply.

         SECTION 10.11.2. Participations. Any Lender may at any time sell to one
or more commercial banks or other Persons (each of such commercial banks and
other Persons being herein called a "Participant") participating interests in
any of the Loans, Commitments, participations in Letters of Credit and Letter of
Credit Outstandings or other interests of such Lender hereunder; provided,
however, that

                  (a) no participation contemplated in this Section 10.11 shall
         relieve such Lender from its Commitments or its other obligations
         hereunder or under any other Loan Document;

                  (b) such Lender shall remain solely responsible for the
         performance of its Commitments and such other obligations;

                  (c) the Borrower and each other Obligor and the Agents shall
         continue to deal solely and directly with such Lender in connection
         with such Lender's rights and obligations under this Agreement and each
         of the other Loan Documents;

                  (d) no Participant, unless such Participant is an Affiliate of
         such Lender, or is itself a Lender, shall be entitled to require such
         Lender to take or refrain from taking any action hereunder or under any
         other Loan Document, except that such Lender may agree

                                      -98-

         with any Participant that such Lender will not, without such
         Participant's consent, take any actions of the type described in clause
         (b) or (c) of Section 10.1, and

                  (e) the Borrower shall not be required to pay any amount under
         Sections 4.3, 4.4, 4.5, 4.6, 10.3 and 10.4 that is greater than the
         amount which it would have been required to pay had no participating
         interest been sold.

The Borrower acknowledges and agrees that, subject to clause (e) above, each
Participant, for purposes of Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 10.3 and
10.4, shall be considered a Lender.

         SECTION 10.12. Other Transactions. Nothing contained herein shall
preclude any Agent or any other Lender from engaging in any transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Affiliates in which the Borrower or such
Affiliate is not restricted hereby from engaging with any other Person.

         SECTION 10.13. Independence of Covenants. All covenants contained in
this Agreement and each other Loan Document shall be given independent effect
such that, in the event a particular action or condition is not permitted by any
of such covenants, the fact that it would be permitted by an exception to, or be
otherwise within the limitations of, another covenant shall not, unless
expressly so provided in such first covenant, avoid the occurrence of a Default
or an Event of Default if such action is taken or such condition exists.

         SECTION 10.14. 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, OR ANY COURSE OF CONDUCT, COURSE OF
DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE
LENDERS OR THE BORROWER SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE
COURTS OF THE STATE OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE
SOUTHERN DISTRICT OF NEW YORK; PROVIDED, HOWEVER, THAT ANY SUIT SEEKING
ENFORCEMENT AGAINST ANY COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT THE
ADMINISTRATIVE AGENT'S OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH
COLLATERAL OR OTHER PROPERTY MAY BE FOUND. THE BORROWER HEREBY EXPRESSLY AND
IRREVOCABLY SUBMITS TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK
AND OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW YORK
FOR THE PURPOSE OF ANY SUCH LITIGATION AS SET FORTH ABOVE AND IRREVOCABLY AGREES
TO BE BOUND BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH SUCH LITIGATION.
THE BORROWER FURTHER IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS BY
REGISTERED MAIL, POSTAGE PREPAID, OR BY PERSONAL SERVICE WITHIN OR WITHOUT THE
STATE OF NEW YORK. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY

                                      -99-
<PAGE>   108

HAVE OR HEREAFTER MAY 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 BORROWER HAS OR
HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY
LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS
PROPERTY, THE BORROWER HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS
OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

         SECTION 10.15. Waiver of Jury Trial. THE AGENTS, THE ISSUER, THE
LENDERS AND THE BORROWER HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE
ANY RIGHTS THEY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED
HEREON, OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS
(WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE AGENTS, THE ISSUER, THE LENDERS OR
THE BORROWER. THE BORROWER ACKNOWLEDGES AND AGREES THAT IT HAS RECEIVED FULL AND
SUFFICIENT CONSIDERATION FOR THIS PROVISION (AND EACH OTHER PROVISION OF EACH
OTHER LOAN DOCUMENT TO WHICH IT IS A PARTY) AND THAT THIS PROVISION IS A
MATERIAL INDUCEMENT FOR THE AGENTS, THE ISSUER AND THE LENDERS ENTERING INTO
THIS AGREEMENT AND EACH SUCH OTHER LOAN DOCUMENT.

                              Item 6.7 Litigation.

         Two separate lawsuits, Keith Vienne, et al. v. Conoco, Inc., et al.,
No. 74,427, and Larry Mouton, et al. v. Conoco, Inc., et al., No. 75,038, were
filed in 1999 in Louisiana state court against six defendants, including Conoco,
Inc., the primary operator of the Rayne Field beginning in the 1950s, and
Guillory Tank Truck Service, Inc., an oilfield waste disposal company. One of
Borrower's subsidiaries, Charles Holston, Inc., purchased the assets of Guillory
Tank Truck Service, Inc. in 1989. These cases have several hundred plaintiffs
who allege that they and their property have been exposed to improperly handled
oil, gas, and oilfield waste over a 40-year period in connection with the
operation of an oilfield approximately four miles north of Rayne, Louisiana. The
plaintiffs allege that Guillory Tank Truck Service, Inc. improperly disposed of
oilfield waste from the field at various unspecified times over the years. The
plaintiffs are seeking an unspecified amount of general, special and exemplary
damages. These cases, which are being consolidated for trial purposes, are in
the initial phase of discovery, and it is too early for us to predict a range of
exposure or a likely outcome. However, we believe that under the terms of the
asset purchase agreement entered into in 1989 to acquire these assets, Charles
Holston, Inc. is not contractually liable for any acts which may result in
liability prior to the acquisition of these assets.

                                   ARTICLE II

                  FORM; EXCHANGE FOR WARRANTS; TRANSFER; TAXES

         Section 2.1 Warrant Register. Each Warrant issued, exchanged or
transferred pursuant to the Recapitalization Agreement shall be registered in a
warrant register (the "Warrant Register"). The Warrant Register shall set forth
the number of each Warrant, the name and address of the holder (a "Holder")
thereof, and the original number of Warrant Shares purchasable upon the exercise
thereof. The Warrant Register will be maintained by the Corporation and will be
available for inspection by any Holder at the principal office of the
Corporation or such other location as the Corporation may designate to the
Holders in the manner set forth in this Agreement. The Corporation shall be
entitled to treat the Holder of any Warrant as the owner in fact thereof for all
purposes and shall not be bound to recognize any equitable or other claim to or
interest in such Warrant on the part of any other person. The Corporation shall
not be liable for complying with a request by a fiduciary or nominee of a
fiduciary to register a transfer of any Warrant which is registered in the name
of such fiduciary or nominee, unless made with the actual knowledge that such
fiduciary or nominee is committing a breach of trust in requesting such
registration of transfer, or with knowledge of such facts that the Corporation's
participation therein amounts to bad faith.

         Section 2.2 Exchange of Warrants for Warrants. (a) The Holder may
exchange this Warrant for another Warrant or Warrants of like kind and tenor
representing in the aggregate the right to purchase the same number of Warrant
Shares which could be purchased pursuant to the Warrant being so exchanged. In
order to effect an exchange permitted by this Section 2.2, the Holder shall
deliver to the Corporation such Warrant accompanied by an Exchange Form in the
form attached hereto as Annex 3 signed by the Holder thereof specifying the
number and denominations of Warrants to be issued in such exchange and the names
in which such Warrants are to be issued. Within ten (10) Business Days of
receipt of such a request, the Corporation shall issue, register and deliver to
the Holder thereof each Warrant to be issued in such exchange.

         (b) Upon receipt of evidence reasonably satisfactory to the Corporation
(an affidavit of the Holder being satisfactory) of the ownership and the loss,
theft, destruction or mutilation of any Warrant, and in the case of any such
loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory
to the Corporation (if the Holder is a creditworthy financial institution or
other creditworthy institutional investor its own agreement being satisfactory)
or, in the case of any such mutilation, upon surrender of such Warrant, the
Corporation shall (at its expense) execute and deliver in lieu of such Warrant a
new Warrant of like kind representing the same rights represented by and dated
the date of such lost, stolen, destroyed or mutilated

                                      -4-
<PAGE>   5

Warrant. Any such new Warrant shall constitute an original contractual
obligation of the Corporation, whether or not the allegedly lost, stolen,
mutilated or destroyed Warrant shall be at any time enforceable by any Person.

         (c) The Corporation shall pay all taxes (other than any applicable
income or similar taxes payable by a Holder of a Warrant) attributable to an
exchange of a Warrant pursuant to this Section 2.2; provided, however, that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance of any Warrant in a name other than
that of the Holder of the Warrant being exchanged.

         Section 2.3 Transfer of Warrant. (a) Subject to Section 2.3(c) hereof
and the Subscription Agreement and Stockholders Agreement, each Warrant may be
transferred by the Holder thereof by delivering to the Corporation such Warrant
accompanied by a properly completed Assignment Form in the form of Annex 2.
Within ten (10) Business Days of receipt of such Assignment Form the Corporation
shall issue, register and deliver to the Holder, subject to Section 2.3(c)
hereof, a new Warrant or Warrants of like kind and tenor representing in the
aggregate the right to purchase the same number of Warrant Shares which could be
purchased pursuant to the Warrant being transferred. In all cases of transfer by
an attorney, the original power of attorney, duly approved, or a copy thereof,
duly certified, shall be deposited and remain with the Corporation. In case of
transfer by executors, administrators, guardians or other legal representatives,
duly authenticated evidence of their authority shall be produced and may be
required to be deposited and remain with the Corporation in its discretion.

         (b) Each Warrant issued in accordance with this Section 2.3 shall bear
the restrictive legend set forth on the face of this Warrant, unless the Holder
or transferee thereof supplies to the Corporation an opinion of counsel,
reasonably satisfactory to the Corporation, that the restrictions described in
such legend are no longer applicable to such Warrant.

         (c) The transfer of Warrants and Warrant Shares shall be permitted, so
long as such transfer is pursuant to a transaction that complies with, or is
exempt from, the provisions of the Securities Act, and the Corporation may
require an opinion of counsel (which may be internal counsel to a Holder) in
form and substance reasonably satisfactory to it to such effect prior to
effecting any transfer of Warrants or Warrant Shares.

                                  ARTICLE III

                EXERCISE OF WARRANT; EXCHANGE FOR WARRANT SHARES

         Section 3.1 Exercise of Warrants. On any Business Day prior to the
Expiration Date, a Holder may exercise a Warrant, in whole or in part, by
delivering to the Corporation such Warrant accompanied by a properly completed
Exercise Form in the form of Annex 1 and a check in an aggregate amount equal to
the product obtained by multiplying (a) the Exercise Price by (b) the number of
Warrant Shares being purchased; provided, however, in the event the Holder
exercises this Warrant in connection with or immediately prior to a sale by the
Holder of Warrant Shares, in lieu of paying the applicable Exercise Price
therefor, the Holder may elect to receive that number of Warrant Shares which is
equal to the number of shares for which this Warrant is being exercised less the
number of shares having a fair market value (determined by

                                      -5-
<PAGE>   6

reference to the price per share at which the Holder is selling the Warrant
Shares) equal to such applicable Exercise Price. Any partial exercise of a
Warrant shall be for a whole number of Warrant Shares only.

         Section 3.2 Issuance of Common Stock. (a) Within ten (10) Business Days
following the delivery date (the "Delivery Date") of (i) an Exercise Form or
Exchange Form in accordance with Section 3.1 or 3.2, (ii) a Warrant and (iii)
any required payments of the Exercise Price, the Corporation shall issue and
deliver to the Holder a certificate or certificates, registered in the name or
names set forth on such notice, representing the Warrant Shares being purchased
or to be received upon such exchange.

         (b) If a Holder shall exercise or exchange a Warrant for less than all
of the Warrant Shares which could be purchased or received thereunder, the
Corporation shall issue to the Holder, within ten (10) Business Days of the
Delivery Date, a new Warrant evidencing the right to purchase the remaining
Warrant Shares. Each Warrant surrendered pursuant to Section 3.1 shall be
canceled.

         (c) The Corporation shall pay all taxes (other than any applicable
income or similar taxes payable by a Holder of a Warrant) attributable to the
initial issuance of Warrant Shares upon the exercise or exchange of a Warrant;
provided, however, that the Corporation shall not be required to pay any tax
which may be payable in respect of any transfer involved in the issuance of any
Warrant or any certificate for Warrant Shares in a name other than that of the
Holder of the Warrant being exercised or exchanged.

         (d) The person in whose name any certificate for shares of Common Stock
is issued upon exercise or exchange of a Warrant shall for all purposes be
deemed to have become the holder of record of such shares on the Delivery Date,
irrespective of the date of delivery of such certificate, except that, if the
Delivery Date is a date when the stock transfer books of the Corporation are
closed, such person shall be deemed to have become the holder of record of such
shares at the close of business on the next succeeding date on which the stock
transfer books are open.

         (e) If any shares of Common Stock required to be reserved for purposes
of the exercise or exchange of a Warrant require registration or approval under
any applicable law, the Corporation will in good faith and as expeditiously as
possible cause such shares to be registered or seek such approval, as
applicable. The Corporation may suspend the exercise of any Warrant so affected
for the period during which such registration or approval is required but not in
effect.

         Section 3.3 Adjustment of Exercise Price and Number of Warrant Shares.
The number and kind of Warrant Shares purchasable upon exercise of each Warrant
shall be subject to adjustment from time to time in accordance with this Section
3.3.

         Section 3.3.1 Subdivisions or Combinations of Common Stock. If, at any
time after the Closing Date, (a) the number of shares of Common Stock
outstanding is increased by a dividend or other distribution payable in shares
of Common Stock or by a subdivision or split-up of shares of Common Stock or (b)
the number of shares of Common Stock outstanding is decreased by a combination
or reverse stock split of shares of Common Stock, then, in each case,

                                      -6-
<PAGE>   7

effective as of the effective date of such event retroactive to the record date,
if any, of such event, (i) the Exercise Price shall be adjusted to a price
determined by multiplying (A) the Exercise Price in effect immediately prior to
such event by (B) a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding immediately prior to such event and the
denominator of which shall be the number of shares of Common Stock outstanding
after giving effect to such event, and (ii) the number of Warrant Shares subject
to purchase upon the exercise of any Warrant shall be adjusted effective at such
time, to a number equal to the product of (A) the number of Warrant Shares
subject to purchase upon the exercise of such Warrant immediately prior to such
event by (B) a fraction, the numerator of which shall be the number of shares of
Common Stock outstanding on a Fully Diluted Basis after giving effect to such
event and the denominator of which shall be the number of shares of Common Stock
outstanding on a Fully Diluted Basis immediately prior to such event.

         Section 3.3.2 Capital Reorganization or Capital Reclassifications. If,
at any time after the Closing Date, there shall be any capital reorganization or
any reclassification of the capital stock of the Corporation (other than a
change in par value or from par value to no par value or from no par value to
par value or as a result of a stock dividend or subdivision, split-up or
combination of shares), then in each case the Corporation shall cause effective
provision to be made so that each Warrant shall, effective as of the effective
date of such event retroactive to the record date, if any, of such event, be
exercisable or exchangeable for the kind and number of shares of stock, other
securities, cash or other property to which a holder of the number of shares of
Common Stock deliverable upon exercise or exchange of such Warrant would have
been entitled upon such reorganization or reclassification and any such
provision shall include adjustments in respect of such stock, securities or
other property that shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Agreement with respect to such Warrant.

         Section 3.3.3 Consolidations and Mergers. If, at any time after the
Closing Date, the Corporation shall consolidate with, merge with or into, or
sell all or substantially all of its assets or property to, another corporation,
then the Corporation shall cause effective provision to be made so that each
Warrant shall, effective as of the effective date of such event retroactive to
the record date, if any, of such event, be exercisable or exchangeable for the
kind and number of shares of stock, other securities, cash or other property to
which a holder of the number of shares of Common Stock deliverable upon exercise
or exchange of such Warrant would have been entitled upon such event.

         Section 3.3.4 Notice; Calculations; Etc. Whenever the Exercise Price
and the number of Warrant Shares shall be adjusted as provided in this Section
3.3, the Corporation shall provide to each Holder a statement, signed by an
Executive Officer, describing in detail the facts requiring such adjustment and
setting forth a calculation of the Exercise Price and the number of Warrant
Shares applicable to each Warrant after giving effect to such adjustment. All
calculations under this Section 3.3 shall be made to the nearest one hundredth
of a cent ($.0001) or to the nearest one-tenth of a share, as the case may be.

         Section 3.3.5 Excluded Transactions. Notwithstanding any other
provision of this Warrant, no adjustment shall be made pursuant to this Section
3.3 in respect of the issuance of Excluded Securities.

                              CERTAIN OTHER RIGHTS

         Section 4.1 Payments in Respect of Dividends and Distributions. If, at
any time prior to the earlier of (i) the Expiration Date and (ii) the
consummation of a Qualified Public Offering, the Corporation pays any dividend
or makes any distribution (whether in cash, property or securities of the
Corporation) on its capital stock which does not result in an adjustment under
Section 3, then the Corporation shall simultaneously pay to the Holder of each
Warrant, the dividend or distribution which would have been paid to such Holder
on the Warrant Shares receivable upon the exercise in full of such Warrant had
such Warrant been fully exercised immediately prior to the record date for such
dividend or distribution or, if no record is taken, the date as of which the
record holders of Common Stock entitled to such dividend or distribution are to
be determined.

         Section 4.2 Fiduciary Duties of the Corporation. The Corporation and
its directors shall owe the holders of the Warrants the same fiduciary duties
that the Corporation and its directors would owe to the Warrant Shares
underlying the Warrants.
