</TABLE>

Notwithstanding the foregoing, the final installment shall be in the amount of
the then outstanding principal balance of the Tranche B Term Loans. In addition,
the then outstanding principal balance of the Tranche B Term Loans shall be due
and payable on the Tranche B Term Loan Termination Date. No installment of any
Tranche B Term Loan shall be reborrowed once repaid.

         (E) Prepayments. In addition to the scheduled payments on the Term
Loans, the Term Loan Borrowers (a) may make the voluntary prepayments described
in Section 2.5(A) for credit against the scheduled payments on the Term Loans
pursuant to Section 2.5(A) and (b) shall make the mandatory prepayments
prescribed in Section 2.5(B) for credit against the scheduled payments on the
Term Loans pursuant to Section 2.5(B), in each case, subject to the prepayment
penalties or premiums described in Section 2.5(C).

         2.2. Revolving Loans.

         (A) Amount of Revolving Loans. Upon the satisfaction of the conditions
precedent set forth in Sections 5.1, 5.2 and 5.3, as applicable, from and
including the Closing Date and prior to the Termination Date, each Lender
severally and not jointly agrees, on the terms and conditions set forth in this
Agreement, to make revolving loans to SDM from time to time, in any Agreed
Currency, in a Dollar Amount not to exceed such Lender's Revolving Loan Pro Rata
Share of Revolving Credit Availability at such time (each individually, a
"REVOLVING LOAN" and, collectively, the "REVOLVING LOANS"); provided, however,
at no time shall the Revolving Credit Obligations exceed the Dollar




                                       43
<PAGE>   44

Amount of the Aggregate Revolving Loan Commitment; provided, further, however,
that upon giving effect to each Advance, the aggregate outstanding principal
Dollar Amount of all Eurocurrency Rate Advances requested in Agreed Currencies
other than Dollars shall not exceed the Maximum Non-Eurodollar Eurocurrency
Amount at any time. Subject to the terms of this Agreement, the Borrowers may
borrow, repay and reborrow Revolving Loans at any time prior to the Termination
Date. The Revolving Loans made on the Closing Date or on or before the third
(3rd) Business Day thereafter shall initially be Floating Rate Loans and
thereafter may be continued as Floating Rate Loans or converted into
Eurocurrency Rate Loans in the manner provided in Section 2.10 and subject to
the other conditions and limitations therein set forth and set forth in this
Article II and set forth in the definition of Interest Period. Revolving Loans
made after the third (3rd) Business Day after the Closing Date shall be, at the
option of the applicable Borrower, selected in accordance with Section 2.10,
either Floating Rate Loans or Eurocurrency Rate Loans. On the Termination Date,
the applicable Borrower shall repay in full the outstanding principal balance of
the Revolving Loans. Each Advance under this Section 2.2 shall consist of
Revolving Loans made by each Lender ratably in proportion to such Lender's
respective Revolving Loan Pro Rata Share.

         (B) Borrowing/Election Notice. SDM shall deliver to the Administrative
Agent a Borrowing/Election Notice, signed by it, in accordance with the terms of
Section 2.8.

         (C) Making of Revolving Loans. Promptly after receipt of the
Borrowing/Election Notice under Section 2.8 in respect of Revolving Loans, the
Administrative Agent shall notify each Lender with a Revolving Loan Commitment
greater than zero by telex or telecopy, or other similar form of transmission,
of the requested Revolving Loan. Each such Lender shall make available its
Revolving Loan in accordance with the terms of Section 2.7. The Administrative
Agent will promptly make the funds so received from the Lenders available to SDM
at the Administrative Agent's office in Chicago, Illinois on the applicable
Borrowing Date and shall disburse such proceeds in accordance with SDM's
disbursement instructions set forth in such Borrowing/Election Notice. The
failure of any Lender to deposit the amount described above with the
Administrative Agent on the applicable Borrowing Date shall not relieve any
other Lender of its obligations hereunder to make its Revolving Loan on such
Borrowing Date

         2.3. Swing Line Loans.

         (A) Amount of Swing Line Loans. Upon the satisfaction of the conditions
precedent set forth in Section 5.1, 5.2 and 5.3, as applicable, from and
including the Closing Date and prior to the Termination Date, the Swing Line
Bank agrees, in its sole discretion, on the terms and conditions set forth in
this Agreement, to make Dollar Denominated Swing Line Loans to SDM from time to
time, in Dollars, and to make Alternate Currency Swing Line Loans to the
Subsidiary Swing Line Borrowers from time to time, in the applicable Alternate
Currencies, in an aggregate Dollar Amount not to exceed the Swing Line
Commitment (each, individually, a "SWING LINE LOAN" and collectively, the "SWING
LINE LOANS"); provided, however, at no time shall the Dollar Amount of the
Revolving Credit Obligations exceed the Aggregate Revolving Loan Commitment; and
provided, further, that at no time shall the sum of (a) the Swing Line Bank's
Revolving Loan Pro Rata Share of the Swing Line Loans, plus (b) the outstanding
Dollar Amount of Revolving Loans made by the Swing Line Bank pursuant to Section
2.2, exceed the Swing Line Bank's Revolving Loan Commitment at such time.
Subject to the terms of this Agreement, and any applicable Alternate Currency
Addendum, the Swing Line Borrowers may borrow, repay and reborrow Swing Line
Loans at any time prior to the Termination Date.



                                       44
<PAGE>   45

         (B) Borrowing/Election Notice. The applicable Swing Line Borrower shall
deliver to the Administrative Agent and the Swing Line Bank a Borrowing/Election
Notice, signed by it, not later than 2:00 p.m. (Chicago time) on the Borrowing
Date of each Swing Line Loan, specifying (i) the applicable Borrowing Date
(which date shall be a Business Day and which may be the same date as the date
the Borrowing/Election Notice is given), and (ii) the aggregate amount of the
requested Swing Line Loan which shall be, for Dollar Denominated Swing Line
Loans, not less than $100,000 (and increments of $100,000 if in excess thereof)
and for Alternate Currency Swing Line Loans, a Dollar Amount not less than
$500,000 (and increments of $100,000 if in excess thereof); provided, that with
respect to Alternate Currency Swing Line Loans, the foregoing requirements may
be modified as appropriate in the applicable Alternate Currency Addendum and, in
any event, with respect to the initial borrowing of Alternate Currency Swing
Line Loans by a particular Subsidiary Swing Line Borrower, such
Borrowing/Election Notice shall be delivered by SDM (on behalf of the applicable
Subsidiary Swing Line Borrower) not later than 2:00 p.m. (Chicago time) on the
date that is ten (10) days prior to such initial Alternate Currency Swing Line
Loan. All Dollar Denominated Swing Line Loans shall bear interest at a rate
quoted by the Administrative Agent to SDM, or, if no such rate is quoted, at the
Floating Rate. All Alternate Currency Swing Line Loans shall bear interest at
applicable local rates and margins to be determined by the Swing Line Bank and
acceptable to the applicable Swing Line Subsidiary Borrower, which rate shall be
set forth in the related Alternate Currency Addendum.

         (C) Making of Swing Line Loans. Promptly after receipt of the
Borrowing/Election Notice under Section 2.3(B) in respect of Swing Line Loans,
the Administrative Agent shall notify each Lender by telex or telecopy, or other
similar form of transmission, of the requested Swing Line Loan. Not later than
4:00 p.m. (Chicago time) (or such other time specified in any Alternate Currency
Addendum) on the applicable Borrowing Date, the Swing Line Bank shall make
available its Swing Line Loan, in funds immediately available (x) with respect
to any Dollar Denominated Swing Line Loan, in Chicago to the Administrative
Agent at its address specified pursuant to Article XV and (y) with respect to
any Alternate Currency Swing Line Loan, to the Administrative Agent at its
address specified in the applicable Alternate Currency Addendum. The
Administrative Agent will promptly make the funds so received from the Swing
Line Bank available to the applicable Swing Line Borrower on the Borrowing Date
at the Administrative Agent's aforesaid address.

         (D) Repayment of Swing Line Loans. Each Swing Line Loan shall be paid
in full by the applicable Swing Line Borrower on or before the thirtieth (30th)
day after the Borrowing Date for such Swing Line Loan. The Swing Line Borrowers
may at any time pay, without penalty or premium, all outstanding Swing Line
Loans or any portion of the outstanding Swing Line Loans which, for Dollar
Denominated Swing Line Loans, shall be in a minimum amount that is not less than
$100,000 (and increments of $100,000 if in excess thereof) and for Alternate
Currency Swing Line Loans, shall be in a minimum Dollar Amount that is not less
than $500,000 (and increments of $100,000 if in excess thereof), upon notice to
the Administrative Agent and the Swing Line Bank. At the request of a Subsidiary
Swing Line Borrower, and in the sole discretion of the Swing Line Bank, an
Alternate Currency Swing Line Loan may be continued as an Alternate Currency
Swing Line Loan for an additional 30-day period from the date such Loan is
otherwise due. In addition, the Administrative Agent (i) may at any time in its
sole discretion with respect to any outstanding Swing Line Loan, or (ii) shall
on the thirtieth (30th) day after the Borrowing Date of any Swing Line Loan




                                       45
<PAGE>   46

(or successive thirtieth (30th) day if such Swing Line Loan has been continued
pursuant to the immediately preceding sentence), (x) if such outstanding Loan is
an Alternate Currency Swing Line Loan, cause such Loan to immediately and
automatically convert into and be redenominated in Dollars equal to the Dollar
Amount of such Alternate Currency Swing Line Loan as of the date of such
conversion and (y) in each instance, require each Lender (including the Swing
Line Bank) to make a Revolving Loan for the benefit of SDM in the Dollar Amount
of such Lender's Revolving Loan Pro Rata Share of such Swing Line Loan, for the
purpose of repaying such Swing Line Loan. Not later than 2:00 p.m. (Chicago
time) on the date of any notice received pursuant to this Section 2.3(D), each
Lender shall make available its required Revolving Loan or Revolving Loans, in
funds immediately available in Chicago to the Administrative Agent at its
address specified pursuant to Article XV. Revolving Loans made pursuant to this
Section 2.3(D) shall initially be Floating Rate Loans and thereafter may be
continued as Floating Rate Loans or converted into Eurocurrency Rate Loans in
the manner provided in Section 2.10 and subject to the other conditions and
limitations therein set forth and set forth in this Article II. Unless a Lender
shall have notified the Swing Line Bank, prior to its making any Swing Line
Loan, that any applicable condition precedent set forth in Sections 5.1, 5.2 and
5.3, as applicable, had not then been satisfied, such Lender's obligation to
make Revolving Loans pursuant to this Section 2.3(D) to repay Swing Line Loans
shall be unconditional, continuing, irrevocable and absolute and shall not be
affected by any circumstances, including, without limitation, (a) any set-off,
counterclaim, recoupment, defense or other right which such Lender may have
against the Administrative Agent, the Swing Line Bank or any other Person, (b)
the occurrence or continuance of a Default or Unmatured Default, (c) any adverse
change in the condition (financial or otherwise) of the Swing Line Borrowers, or
(d) any other circumstances, happening or event whatsoever. In the event that
any Lender fails to make payment to the Administrative Agent of any amount due
under this Section 2.3(D), the Administrative Agent shall be entitled to
receive, retain and apply against such obligation the principal and interest
otherwise payable to such Lender hereunder until the Administrative Agent
receives such payment from such Lender or such obligation is otherwise fully
satisfied. In addition to the foregoing, if for any reason any Lender fails to
make payment to the Administrative Agent of any amount due under this Section
2.3(D), such Lender shall be deemed, at the option of the Administrative Agent,
to have unconditionally and irrevocably purchased from the Swing Line Bank,
without recourse or warranty, an undivided interest and participation in the
applicable Swing Line Loan in the amount of such Revolving Loan, and such
interest and participation may be recovered from such Lender together with
interest thereon at the Federal Funds Effective Rate for each day during the
period commencing on the date of demand and ending on the date such amount is
received. On the Termination Date, the Swing Line Borrowers shall repay in full
the outstanding principal balance of the Swing Line Loans.

         (E) Other Provisions Applicable to Alternate Currency Swing Line Loans.
The specification of payment of Alternate Currency Swing Line Loans in the
related Alternate Currency at a specific place pursuant to this Agreement or the
applicable Alternate Currency Addendum is of the essence. Such Alternate
Currency shall be the currency of account and payment of such Loans under this
Agreement and the applicable Alternate Currency Addendum. Notwithstanding
anything in this Agreement, the obligation of the applicable Subsidiary Swing
Line Borrower in respect of such Loans shall not be discharged by an amount paid
in any other currency or at another place, whether pursuant to a judgment or
otherwise, to the extent the amount so paid, on prompt conversion into the
applicable Alternate Currency and transfer to the Swing Line Bank or Lenders
under normal banking procedure, does not yield the amount of such Alternate
Currency due under this Agreement and the




                                       46
<PAGE>   47
applicable Alternate Currency Addendum. In the event that any payment, whether
pursuant to a judgment or otherwise, upon conversion and transfer, does not
result in payment of the amount of such Alternate Currency due under this
Agreement or the applicable Alternate Currency Addendum, the Swing Line Bank
shall have an independent cause of action against each of the Borrowers for the
currency deficit.

         (F) Addition of Subsidiary Swing Line Borrowers. SDM may at any time or
from time to time, with the consent of the Administrative Agent, add as a party
to this Agreement any Subsidiary to be a "Subsidiary Swing Line Borrower"
hereunder by the execution and delivery to the Administrative Agent and the
Lenders of (a) a duly completed Assumption Letter by such Subsidiary, with the
written consent of SDM at the foot thereof and (b) such other guaranty, security
documents and legal opinions as may be reasonably required by the Administrative
Agent, such documents with respect to any additional Subsidiaries to be
substantially similar in form and substance to the Loan Documents executed as of
the Closing Date. Upon such execution, delivery and consent, such Subsidiary
shall for all purposes be a party hereto as a Subsidiary Swing Line Borrower as
fully as if it had executed and delivered this Agreement. So long as the
principal of and interest on any Advances made to any Subsidiary Swing Line
Borrower under this Agreement shall have been repaid or paid in full and all
other obligations of such Subsidiary Swing Line Borrower under this Agreement
shall have been fully performed, SDM may, by not less than five (5) Business
Days' prior notice to the Administrative Agent (which shall promptly notify the
Lenders thereof), terminate such Subsidiary Swing Line Borrower's status as a
"Subsidiary Swing Line Borrower".

         2.4. Rate Options for all Advances; Maximum Interest Periods. Dollar
Denominated Swing Line Loans shall bear interest at a rate quoted by the
Administrative Agent to SDM, but if no such rate is quoted, such Swing Line
Loans shall be Floating Rate Advances. Alternate Currency Swing Line Loans shall
bear interest at a rate and margin to be determined by the Swing Line Bank and
acceptable to the applicable Subsidiary Swing Line Borrower, which rate shall be
set forth in the applicable Alternate Currency Addendum. The Revolving Loans and
Term Loans may be Floating Rate Advances or Eurocurrency Rate Advances, or a
combination thereof, selected by the Borrowers in accordance with Section 2.10;
provided, however, notwithstanding anything herein to the contrary, for the
period from the Closing Date to the date upon which the Arranger confirms that
the loan syndication process for the Tranche B Term Loans has been completed
(the "SYNDICATION PERIOD"), all Tranche B Term Loans shall be Floating Rate
Advances. The Borrowers may select, in accordance with Section 2.10, Rate
Options and Interest Periods applicable to portions of the Revolving Loans and
the Term Loans; provided that there shall be no more than twelve (12) Interest
Periods in effect with respect to all of the Loans at any time; provided,
further, that the Opt-Out Rate shall only apply to the extent required by
Section 2.23.

         2.5. Optional Payments; Mandatory Prepayments.

         (A) Optional Payments. The Borrowers may from time to time and at any
time upon at least one (1) Business Day's prior written notice repay or prepay,
without penalty or premium (subject to Section 2.5(C)), all or any part of
outstanding Swing Line Loans which, for Dollar Denominated Swing Line Loans,
shall be in an aggregate minimum amount of not less than $100,000 (and
increments of $100,000 if in excess thereof) and for Alternate Currency Swing
Line Loans, shall be in an aggregate minimum Dollar Amount of not less than
$500,000 (and increments of $100,000 if in excess thereof), and in respect of
any other Floating Rate Advances in an aggregate minimum



                                       47
<PAGE>   48

amount of $5,000,000 and in integral multiples of $1,000,000 in excess thereof.
Eurocurrency Rate Advances may be voluntarily repaid or prepaid prior to the
last day of the applicable Interest Period, subject to the indemnification
provisions contained in Section 4.4 and subject to Section 2.5(C), in an
aggregate minimum Dollar Amount of $5,000,000 and in integral multiples of
$1,000,000 in excess thereof; provided, that the applicable Borrower may not so
prepay Eurocurrency Rate Advances unless it shall have provided at least three
(3) Business Days' prior written notice to the Administrative Agent of such
prepayment.

         (B)   Mandatory Prepayments.

               (i)  Mandatory Prepayments of Term Loans.

               (a)  Asset Sales. Upon the consummation of any Asset Sale by the
                    Parent or any of its Subsidiaries or the receipt by the
                    Parent or any Subsidiary of proceeds from any condemnation
                    proceeding or from insurance in connection with any loss,
                    except as provided in the second sentence of this Section
                    2.5(B)(i)(a), and except to the extent that the Net Cash
                    Proceeds of such Asset Sale or other such net proceeds, when
                    combined with the Net Cash Proceeds of all such Asset Sales
                    or other such proceeds during the immediately preceding
                    twelve-month period, do not exceed $5,000,000 in the
                    aggregate, within three (3) Business Days after the Parent's
                    or any of its Subsidiaries' (i) receipt of any Net Cash
                    Proceeds from any such Asset Sale or other such proceeds, or
                    (ii) conversion to cash or Cash Equivalents of non-cash
                    proceeds (whether principal or interest and including
                    securities, release of escrow arrangements or lease
                    payments) received from any Asset Sale, the Borrowers shall
                    make a mandatory prepayment of the Obligations in an amount
                    equal to one hundred percent (100%) of such Net Cash
                    Proceeds or other such proceeds or such proceeds converted
                    from non-cash to cash or Cash Equivalents. Net Cash Proceeds
                    of Asset Sales with respect to which the Borrowers shall
                    have given the Administrative Agent written notice within
                    three (3) Business Days after such Asset Sale of its
                    intention to replace the assets or use such Net Cash
                    Proceeds to acquire other like-kind assets within one
                    hundred eighty (180) days following such Asset Sale shall
                    not be subject to the provisions of the first sentence of
                    this Section 2.5(B)(i)(a) unless and to the extent that such
                    applicable period shall have expired without such
                    replacement having been made.

               (b)  Excess Cash Flow. Simultaneously with the delivery of the
                    annual audited financial statements required to be delivered
                    pursuant to Section 7.1(A)(ii) for each fiscal year
                    beginning with the fiscal year ending September 30, 2001, if
                    at such time the Leverage Ratio is greater than or equal to
                    2.50 to 1.00, the Parent shall calculate Excess Cash Flow
                    for such fiscal year and shall make a mandatory prepayment
                    of the Obligations, payable not later than the earlier of
                    ten (10) days after such financial statements and
                    calculation are delivered or one hundred (100) days after
                    the end of such fiscal year, in an amount equal to fifty
                    percent (50%) of such Excess Cash Flow.

               (c)  Equity Financings. Upon the consummation of any Financing by
                    the Parent, any Borrower or any Subsidiary constituting a
                    sale or issuance of any Disqualified Stock or Equity
                    Interests (other than in connection with stock issued to
                    fund Permitted Acquisitions) thereby, within three (3)
                    Business Days after the Parent's the Borrowers' or any of
                    their respective Subsidiaries' receipt of any Net Cash
                    Proceeds from such Financing, the Borrowers shall make a
                    mandatory prepayment of the Obligations in an amount equal
                    to fifty percent (50%) of such Net Cash Proceeds.

               (d)  Debt Financings. Upon the consummation of any Financing by
                    the Parent, any Borrower or any Subsidiary thereof
                    constituting a sale or issuance of any Indebtedness in the
                    form of debt securities thereby, within three (3) Business
                    Days after the Parent's, the Borrowers' or any of their
                    respective Subsidiaries' receipt of any Net Cash Proceeds
                    from such Financing, the Borrowers shall make a mandatory
                    prepayment of the Obligations in an amount equal to one
                    hundred percent (100%), or, at any time after the Leverage
                    Ratio is less than 2.50 to 1.00, fifty percent (50%) of such
                    Net Cash Proceeds.

               (e)  No Consent. Nothing in this Section 2.5(B)(i) shall be
                    construed to constitute the Lenders' consent to any
                    transaction referred to in clause (a), (c) or (d) above
                    which is not expressly permitted by the terms of this
                    Agreement.

               (f)  Application of Designated Prepayments. Each mandatory
                    prepayment required by clauses (a), (b), (c) and (d) of this
                    Section 2.5(B)(i) shall be referred to herein as a
                    "DESIGNATED PREPAYMENT." Designated Prepayments shall be
                    allocated and applied to the Obligations as follows:

                    (1)  the amount of each Designated Prepayment shall be
                         applied first ratably to the Tranche A Term Loans and
                         the Tranche B Term Loans, with fifty percent (50%) of
                         each prepayment being applied to unpaid installments in
                         the order of maturity and fifty percent (50%) being
                         applied to unpaid installments in the inverse order of
                         maturity; provided, however, that so long as any
                         Tranche A Term Loans are outstanding, any Tranche B
                         Term Loan Lender may decline all or any portion of a
                         Designated Prepayment in an amount that shall not
                         exceed the outstanding principal balance of the Tranche
                         A Term Loans, which declined amount shall be applied to
                         the then remaining installments of the Tranche A Term
                         Loans; and

                    (2)  following the payment in full of the Tranche A Term
                         Loans and the Tranche B Term Loans, the amount of each
                         Designated Prepayment shall be applied to repay
                         Revolving Loans (but shall reduce Revolving Loan
                         Commitments only at the option of the Required Lenders)
                         and following the payment in full of the Revolving
                         Loans, the amount of each Designated Prepayment shall
                         be applied first to interest on the Reimbursement
                         Obligations, then to principal on the Reimbursement




                                       49
<PAGE>   50

                         Obligations, then to fees on account of Letters of
                         Credit and then, to the extent any L/C Obligations are
                         contingent, deposited with the Administrative Agent as
                         cash collateral in respect of such L/C Obligations.

          (ii) Mandatory Prepayments of Revolving Loans.

          (a)  In addition to repayments under Section 2.5(B)(i), if at any time
               and for any reason (other than fluctuations in currency exchange
               rates) the Dollar Amount of the Revolving Credit Obligations are
               greater than the Aggregate Revolving Loan Commitment, the
               Borrowers shall immediately make a mandatory prepayment of the
               Obligations in an amount equal to such excess.

          (b)  If on the last Business Day of any month:

               (1)  The Dollar Amount of the Revolving Loan Obligations exceeds
                    one hundred five percent (105%) of the Aggregate Revolving
                    Loan Commitment as a result of fluctuations in currency
                    exchange rates, SDM shall immediately prepay Loans for the
                    ratable benefit of the Lenders (to be applied to such Loans
                    as SDM shall direct at the time of such payment) in an
                    aggregate amount such that after giving effect thereto the
                    Dollar Amount of the Revolving Credit Obligations is less
                    than or equal to the Aggregate Revolving Loan Commitment;

               (2)  The Dollar Amount of the Eurocurrency Rate Loans exceeds one
                    hundred five percent (105%) of the Maximum Non-Eurodollar
                    Eurocurrency Amount as a result of fluctuations in currency
                    exchange rates, SDM shall immediately prepay Loans for the
                    ratable benefit of the Lenders (to be applied to such Loans
                    as SDM shall direct at the time of such payment) in an
                    aggregate amount such that after giving effect thereto the
                    Dollar Amount of the Outstanding Eurocurrency Rate Loans is
                    less than or equal to the Maximum Non-Eurodollar
                    Eurocurrency Amount; or

               (3)  The Dollar Amount of all outstanding Swing Line Loans
                    exceeds one hundred five percent (105%) of the Swing Line
                    Commitments as a result of fluctuations in currency exchange
                    rates, the applicable Swing Line Borrower shall on such date
                    prepay, or cause to be prepaid, Swing Line Loans in an
                    aggregate amount such that after giving effect thereto the
                    Dollar Amount of all such Swing Line Loans is less than or
                    equal to the aggregate Swing Line Commitments.

         (iii) Application of Prepayments. On the date any Designated
Prepayments or any prepayment under clause (ii) above is received by the
Administrative Agent, such prepayment shall be applied first to Floating Rate
Loans and Alternate Currency Swing Line Loans bearing a fluctuating rate of
interest and to any Eurocurrency Rate Loans and Opt-Out Loans maturing on such
date and then to subsequently maturing Eurocurrency Rate Loans and Opt-Out Loans
in order of maturity.



                                       50
<PAGE>   51

         (C) Call Protection. Notwithstanding anything herein to the contrary,
any optional prepayments of the Tranche B Term Loans made pursuant to Section
2.5(A) or any Designated Prepayments accepted by the Tranche B Term Loan Lenders
(other than Designated Prepayments made pursuant to Sections 2.5(B)(i)(a) or
(b)), in each case, whether as a result of acceleration or otherwise and on any
date that is (i) on or prior to the first anniversary of the Closing Date shall
be equal to 102% of such prepaid amount and (ii) after the first anniversary of
the Closing Date and on or prior to the second anniversary of the Closing Date
shall be equal to 101% of such prepaid amount. Amounts prepaid after the second
anniversary of the Closing Date shall be repaid without penalty or premium other
than amounts required pursuant to the indemnification provisions contained in
Section 4.4, if applicable.

         2.6. Reduction of Commitments. The Borrowers may permanently reduce the
Aggregate Revolving Loan Commitment in whole, or in part ratably among the
Lenders, in an aggregate minimum Dollar Amount of $5,000,000 with respect to
each such Commitment and integral multiples of $1,000,000 in excess of that
amount with respect to each such Commitment (unless the Aggregate Revolving Loan
Commitment is reduced in whole), upon at least one (1) Business Day's prior
written notice to the Administrative Agent, which notice shall specify the
amount of any such reduction; provided, however, that the amount of the
Aggregate Revolving Loan Commitment may not be reduced below the aggregate
principal Dollar Amount of the outstanding Revolving Credit Obligations. All
accrued commitment fees shall be payable on the effective date of any
termination of all or any part of the obligations of the Lenders to make Loans
hereunder.

         2.7. Method of Borrowing. Not later than 12:00 p.m. (Chicago time) on
each Borrowing Date, each Lender shall make available its Revolving Loan or Term
Loan, in immediately available funds in the Agreed Currency to the
Administrative Agent at its address specified pursuant to Article XV, unless the
Administrative Agent has notified the Lenders that such Loan is to be made
available to the applicable Borrower at the Administrative Agent's Eurocurrency
Payment Office, in which case each Lender shall make available its Loan or
Loans, in funds immediately available to the Administrative Agent at its
Eurocurrency Payment Office, not later than 12:00 p.m. (local time in the city
of the Administrative Agent's Eurocurrency Payment Office) in the Agreed
Currency designated by the Administrative Agent. The Administrative Agent will
promptly make the funds so received from the Lenders available to the applicable
Borrower at the Administrative Agent's aforesaid address.

         2.8. Method of Selecting Types, Currency and Interest Periods for
Advances. The applicable Borrower shall select the Type of Advance and, in the
case of each Eurocurrency Rate Advance, the Interest Period and Agreed Currency,
and, in the case of Alternate Currency Swing Line Loans, the Alternate Currency
applicable to each Advance from time to time; provided, that an Advance shall
only consist of Opt-Out Loans to the extent required by Section 2.23. The
applicable Borrower shall give the Administrative Agent irrevocable notice in
substantially the form of Exhibit B hereto (a "BORROWING/ELECTION NOTICE") not
later than 12:00 p.m. (Chicago time) (a) on or before the Borrowing Date of each
Floating Rate Advance and (b) three (3) Business Days before the Borrowing Date
for each Eurocurrency Rate Advance to be made in Dollars specifying: (i) the
Borrowing Date (which shall be a Business Day) of such Advance; (ii) the
aggregate amount of such Advance; (iii) the Type of Advance selected (which Type
shall be limited to Eurocurrency Rate




                                       51
<PAGE>   52

Loans and Floating Rate Loans); and (iv) in the case of each Eurocurrency Rate
Advance, the Interest Period and Agreed Currency applicable thereto. The
Borrowers shall select Interest Periods so that, to the best of their knowledge,
it will not be necessary to prepay all or any portion of any Eurocurrency Rate
Loan or Opt-Out Loan prior to the last day of the applicable Interest Period in
order to make mandatory prepayments as required pursuant to the terms hereof.
Each Floating Rate Advance, each Alternate Currency Swing Line Loan bearing a
fluctuating rate of interest and all Obligations other than Loans shall bear
interest from and including the date of the making of such Advance, in the case
of Loans, and the date such Obligation is due and owing in the case of such
other Obligations, to (but not including) the date of repayment thereof at the
Floating Rate or rate applicable to such Alternate Currency Swing Line Loans, as
applicable, changing when and as such Floating Rate or rate applicable to such
Alternate Currency Swing Line Loans, as applicable, changes. Changes in the rate
of interest on that portion of any Advance maintained as a Floating Rate Loan
will take effect simultaneously with each change in the Alternate Base Rate.
Changes in the rate of interest on any portion of any Alternate Currency Swing
Line Loan bearing a fluctuating rate of interest will take effect simultaneously
with each change in such rate. Each Eurocurrency Rate Advance shall bear
interest from and including the first day of the Interest Period applicable
thereto to (but not including) the last day of such Interest Period at the
interest rate determined as applicable to such Eurocurrency Rate Advance and
shall change as and when the Applicable Eurocurrency Margin changes.

         2.9. Minimum Amount of Each Advance. Dollar Denominated Swing Line
Loans shall be in a minimum amount of $100,000 (and increments of $100,000 in
excess thereof) and Alternate Currency Swing Line Loans shall be in a minimum
Dollar Amount of $500,000 (and increments of $100,000 in excess thereof). Each
other Advance (other than an Advance to repay Swing Line Loans or a
Reimbursement Obligation) shall be in the minimum Dollar Amount of $5,000,000
(or the approximate Equivalent Amount of any Agreed Currency other than Dollars
or any Alternate Currency) and in Dollar Amount multiples of $1,000,000 (or the
approximate Equivalent Amount of any Agreed Currency other than Dollars or any
Alternate Currency) if in excess thereof (or such other amounts as may be
specified in the applicable Alternate Currency Addendum), provided, however,
that any Floating Rate Advance may be in the amount of the unused Aggregate
Revolving Loan Commitment.

         2.10. Method of Selecting Types, Currency and Interest Periods for
Conversion and Continuation of Advances.

         (A) Right to Convert. The applicable Borrower may elect from time to
time, subject to the provisions of Section 2.4 and this Section 2.10, to convert
all or any part of a Loan of any Type into any other Type or Types of Loans;
provided that any conversion of any Eurocurrency Rate Advance shall be made on,
and only on, the last day of the Interest Period applicable thereto.

         (B) Automatic Conversion and Continuation. Floating Rate Loans shall
continue as Floating Rate Loans unless and until such Floating Rate Loans are
converted into Eurocurrency Rate Loans. Eurocurrency Rate Loans shall continue
as Eurocurrency Rate Loans until the end of the then applicable Interest Period
therefor, at which time such Eurocurrency Rate Loans with an Agreed Currency of
Dollars shall be automatically converted into Floating Rate Loans unless the
applicable Borrower shall have given the Administrative Agent notice in
accordance with Section 2.10(D) requesting that, at the end of such Interest
Period, such Eurocurrency Rate Loans continue as a



                                       52
<PAGE>   53

Eurocurrency Rate Loan. Unless a Borrowing/Election Notice shall have timely
been given in accordance with the terms of this Section 2.10, Eurocurrency Rate
Advances in an Agreed Currency other than Dollars shall continue with an
Interest Period of one (1) month.

         (C) No Conversion Post-Default or Post-Unmatured Default.
Notwithstanding anything to the contrary contained in Section 2.10(A) or Section
2.10(B), no Loan may be converted into or continued as a Eurocurrency Rate Loan
(except with the consent of the Required Lenders) when any Default or Unmatured
Default has occurred and is continuing.

         (D) Borrowing/Election Notice. The applicable Borrower shall give the
Administrative Agent irrevocable notice (a "BORROWING/ELECTION NOTICE") of each
conversion of a Floating Rate Loan into a Eurocurrency Rate Loan or continuation
of a Eurocurrency Rate Loan not later than 12:00 p.m. (Chicago time) three (3)
Business Days prior to the date of the requested conversion or continuation,
specifying: (1) the requested date (which shall be a Business Day) of such
conversion or continuation; (2) the amount and Type of the Loan to be converted
or continued; and (3) the amount of Eurocurrency Rate Loan(s), if applicable,
into which such Loan is to be converted or continued, the Agreed Currency and
the duration of the Interest Period applicable thereto.

         (E) Conversion/Continuation in Same Agreed Currency. Notwithstanding
anything herein to the contrary, Eurocurrency Rate Advances in an Agreed
Currency may be continued as Eurocurrency Rate Advances only in the same Agreed
Currency.

         (F) Conversion/Continuation of Opt-Out Loans. Each reference in this
Section 2.10 to Eurocurrency Rate Loans shall apply to Opt-Out Loans which,
together with such Eurocurrency Rate Loans, constitute the same Eurocurrency
Rate Advance pursuant to Section 2.23; provided, that notwithstanding anything
herein to the contrary, Opt-Out Loans may not be converted to Eurocurrency Loans
in the applicable Opt-Out Currency.

         2.11. Default Rate. After the occurrence and during the continuance of
a Default, at the option of the Administrative Agent or at the direction of the
Required Lenders:

               (i) the interest rate(s) applicable to the Obligations and all
         other fees (including the fees payable under Section 3.8 with respect
         to Letters of Credit and the non-utilization fee payable under Section
         2.15(C)(ii)) shall be equal to (x) the interest rates and fees
         calculated based on the maximum (Level IV Status) Applicable Floating
         Rate Margins, Applicable Eurocurrency Margins and Applicable Commitment
         Fee Percentage, as applicable, under the pricing grid set forth in
         Section 2.15(D)(ii) (and, in the case of the non-utilization fee, the
         then applicable fee) plus (y) two percent (2.00%) per annum for all
         such Obligations and fees; and

               (ii) the principal balance of, and, to the extent permitted by
         law, any overdue interest on any Alternate Currency Swing Line Loan
         shall bear interest, payable upon demand, for each day until paid at
         the rate per annum equal to two percent (2.00%) plus the interest rate
         applicable to such Alternate Currency Swing Line Loan immediately prior
         to the Default.

         2.12. Method of Payment. All payments of principal, interest, fees,
commissions and L/C Obligations hereunder shall be made, without setoff,
deduction or counterclaim (unless indicated



                                       53
<PAGE>   54

otherwise in Section 2.15(E)), in immediately available funds to the
Administrative Agent (i) at the Administrative Agent's address specified
pursuant to Article XV in immediately available funds with respect to Advances
or other Obligations denominated in Dollars and (ii) at the Administrative
Agent's Eurocurrency Payment Office in immediately available funds with respect
to any Advance or other Obligations denominated in an Agreed Currency other than
Dollars (or, with respect to Alternate Currency Swing Line Loans, at such other
office specified in any applicable Alternate Currency Addendum), or at any other
Lending Installation of the Administrative Agent specified in writing by the
Administrative Agent to the Borrowers, by 1:00 p.m. (Chicago time) on the date
when due and shall be made ratably among the Lenders (unless such amount is not
to be shared ratably in accordance with the terms hereof). Each Advance shall be
repaid or prepaid in the Agreed Currency in which it was made in the amount
equal to the amount borrowed in such Agreed Currency and interest payable
thereon shall also be paid in such currency. Each payment delivered to the
Administrative Agent for the account of any Lender shall be delivered promptly
by the Administrative Agent to such Lender in the same type of funds which the
Administrative Agent received at its address specified pursuant to Article XV or
at any Lending Installation specified in a notice received by the Administrative
Agent from such Lender. Each reference to the Administrative Agent in this
Section 2.12 shall also be deemed to refer, and shall apply equally, to the
Issuing Bank, in the case of payments required to be made by SDM to the Issuing
Bank pursuant to Article III.

         All payments to be made by the Borrowers hereunder in respect of any
Alternate Currency Swing Line Loans shall be made in the currencies in which
such Loans are denominated and in funds immediately available, at the office or
branch from which the Loan was made pursuant to Section 2.3(C) and the
applicable Alternate Currency Addendum not later than 3:00 p.m. (local time) on
the date on which such payment shall become due. Promptly upon receipt of any
payment of principal of the Alternate Currency Swing Line Loans the Swing Line
Bank shall give written notice to the Administrative Agent by telex or telecopy
of the receipt of such payment.

         Notwithstanding the foregoing provisions of this Section, if, after the
making of any Advance in any currency other than Dollars, currency control or
exchange regulations are imposed in the country which issues such Agreed
Currency or Alternate Currency, as applicable, with the result that different
types of such Agreed Currency or Alternate Currency, as applicable, (the "NEW
CURRENCY") are introduced and the type of currency in which the Advance was made
(the "ORIGINAL CURRENCY") no longer exists or any Borrower is not able to make
payment to the Administrative Agent for the account of the Lenders or Swing Line
Bank, as applicable, in such Original Currency, then all payments to be made by
the Borrowers hereunder in such currency shall be made to the Administrative
Agent or Swing Line Bank, as applicable, in such amount and such type of the New
Currency or Dollars as shall be equivalent to the amount of such payment
otherwise due hereunder in the Original Currency, it being the intention of the
parties hereto that the Borrowers take all risks of the imposition of any such
currency control or exchange regulations. In addition, notwithstanding the
foregoing provisions of this Section, if, after the making of any Advance in any
currency other than Dollars, the applicable Borrower is not able to make payment
to the Administrative Agent for the account of the Lenders or the Swing Line
Bank in the type of currency in which such Advance was made because of the
imposition of any such currency control or exchange regulation, then such
Advance shall instead be repaid when due in Dollars in a principal amount equal
to the Dollar Amount (as of the date of repayment) of such Advance.

         2.13. Evidence of Debt.

         (A) Loan Account. Each Lender shall maintain in accordance with its
usual practice an account or accounts (a "LOAN ACCOUNT") evidencing the
Indebtedness of the Borrowers to such Lender owing to such Lender from time to
time, including the amounts of principal and interest payable and paid to such
Lender from time to time hereunder.

         (B) Register. The Register maintained by the Administrative Agent
pursuant to Section 14.3(C) shall include a control account, and a subsidiary
account for each Lender, in which accounts (taken together) shall be recorded
(i) the date and the amount of each Loan made hereunder, the Type thereof and
the Interest Period, if any, applicable thereto, (ii) the amount and the
currency of any principal or interest due and payable or to become due and
payable from the Borrowers to each Lender hereunder, (iii) the effective date
and amount of each Assignment Agreement delivered to and accepted by it and the
parties thereto pursuant to Section 14.3, (iv) the amount of any sum received by
the Administrative Agent hereunder for the account of the Lenders and each
Lender's share thereof, and (v) all other appropriate debits and credits as
provided in this Agreement, including, without limitation, all fees, charges,
expenses and interest.

         (C) Entries in Loan Account and Register. The entries made in the Loan
Account, the Register and the other accounts maintained pursuant to subsections
(A) or (B) of this Section shall be conclusive and binding for all purposes,
absent manifest error, unless the applicable Borrower objects to information
contained in the Loan Accounts, the Register or the other accounts within thirty
(30) days of the applicable Borrower's receipt of such information; provided
that the failure of any Lender or the Administrative Agent to maintain such
accounts or any error therein shall not in any manner affect the obligation of
the Borrowers to repay the Loans in accordance with the terms of this Agreement.

         (D) Notes Issued Upon Request. Any Lender may request that the
Revolving Loans, Tranche A Term Loans or Tranche B Term Loans made by it each be
evidenced by a promissory note in substantially the forms of Exhibit K-1, K-2 or
K-3, respectively, to evidence such Lender's Revolving Loans, Tranche A Term
Loans or Tranche B Term Loans, as applicable. In such event, the applicable
Borrower shall prepare, execute and deliver to such Lender a promissory note for
such Loans payable to the order of such Lender and in a form approved by the
Administrative Agent and consistent with the terms of this Agreement.
Thereafter, the Loans evidenced by such promissory note and interest thereon
shall at all times (including after assignment pursuant to Section 14.3) be
represented by one or more promissory notes in such form payable to the order of
the payee named therein.

         2.14. Telephonic Notices. The Borrowers authorize the Lenders and the
Administrative Agent to extend, convert or continue Advances, effect selections
of Types of Advances and to transfer funds based on telephonic notices made by
any person or persons the Administrative Agent or any Lender in good faith
believes to be acting on behalf of the applicable Borrower. The Borrowers agree
to deliver promptly to the Administrative Agent a written confirmation, signed
by an Authorized Officer, if such confirmation is requested by the
Administrative Agent or any Lender, of each telephonic notice. If the written
confirmation differs in any material respect from the action taken by the
Administrative Agent and the Lenders, the records of the Administrative Agent
and the Lenders shall govern absent manifest error. In case of disagreement
concerning such notices, if the




                                       55
<PAGE>   56

Administrative Agent has recorded telephonic borrowing notices, such recordings
will be made available to the applicable Borrower upon its request therefor.

         2.15. Promise to Pay; Interest and Commitment Fees; Non-Utilization
Fees; Interest Payment Dates; Interest and Fee Basis; Taxes; Loan and Control
Accounts.

         (A) Promise to Pay; Joint and Several Liability of the Borrowers. All
Advances shall be paid in full by the applicable Borrower or Borrowers on the
earlier of (i) the Termination Date and (ii) the Facility Termination Date. Each
Borrower unconditionally promises to pay when due the principal amount of each
Loan and all other Obligations incurred by it, and to pay all unpaid interest
accrued thereon, in accordance with the terms of this Agreement and the other
Loan Documents, and confirms that all Borrowers organized under the laws of a
jurisdiction located in the United States of America shall be jointly and
severally liable for all of the Obligations.

         (B) Interest Payment Dates. Interest accrued on each Floating Rate Loan
shall be payable on each Payment Date (commencing with the first such date to
occur after the date hereof), upon any prepayment whether by acceleration or
otherwise, and at maturity (whether by acceleration or otherwise). Interest
accrued on each Eurocurrency Rate Loan or Opt-Out Loan shall be payable on the
last day of its applicable Interest Period, on any date on which the
Eurocurrency Rate Loan or Opt-Out Loan is prepaid, whether by acceleration or
otherwise, and at maturity. Interest accrued on each Eurocurrency Rate Loan or
Opt-Out Loan having an Interest Period longer than three months shall also be
payable on the last day of each three-month interval during such Interest
Period. Interest accrued on the principal balance of all other Obligations shall
be payable in arrears (i) on each Payment Date, commencing on the first such day
following the incurrence of such Obligation, (ii) upon repayment thereof in full
or in part, and (iii) if not theretofore paid in full, at the time such other
Obligation becomes due and payable (whether by acceleration or otherwise).

         (C) Commitment Fees; Non-Utilization Fee; Fee Letter.

             (i) SDM shall pay to the Administrative Agent, for the account of
         the Lenders in accordance with their Revolving Loan Pro Rata Shares,
         from and after the Effective Date until the date on which the Aggregate
         Revolving Loan Commitment shall be terminated in whole, a commitment
         fee accruing at the rate of the then Applicable Commitment Fee
         Percentage, on the amount by which (A) the Aggregate Revolving Loan
         Commitment in effect from time to time exceeds (B) the Revolving Credit
         Obligations (excluding the outstanding principal amount of the Swing
         Line Loans) in effect from time to time. All such commitment fees
         payable under this clause (C) shall be payable quarterly in arrears on
         each Payment Date occurring after the Effective Date (with the first
         such payment being calculated for the period from the Effective Date
         and ending on December 31, 2000), and, in addition, on any date on
         which the Aggregate Revolving Loan Commitment shall be terminated in
         whole.

             (ii) If, on any date, the outstanding principal amount of the
         Revolving Loans (excluding Swing Line Loans) and Letters of Credit is
         less than fifty percent (50%) of the Aggregate Revolving Loan
         Commitment on such date, SDM shall pay to the Administrative Agent, for
         the account of the Lenders in accordance with their Revolving Loan Pro
         Rata Shares, a non-utilization fee in the amount of 0.25% per annum on
         the unused portion of the Aggregate Revolving Loan Commitment.

             (iii) The Parent and the Borrowers agree to pay to the
         Administrative Agent for the sole account of the Administrative Agent
         and the Arranger (unless otherwise agreed between the Administrative
         Agent and the Arranger and any Lender) the fees set forth in the letter
         agreement among the Administrative Agent, the Arranger, SIC and the
         Parent dated October 24, 2000, payable at the times and in the amounts
         set forth therein.

         (D) Interest and Fee Basis; Applicable Floating Rate Margins,
Applicable Eurocurrency Margins and Applicable Commitment Fee Percentage.

             (i) Interest on all Loans for which the Prime Rate is the basis
         shall be calculated for actual days elapsed on the basis of a 365-day
         year. Interest on all other Loans (except as provided otherwise in the
         applicable Alternate Currency Addendum in the case of an Alternate
         Currency Swing Line Loan) and fees shall be calculated for actual days
         elapsed on the basis of a 360-day year. Interest shall be payable for
         the day an Obligation is incurred but not for the day of any payment on
         the amount paid if payment is received prior to 2:00 p.m. (Chicago
         time) at the place of payment. If any payment of principal of or
         interest on a Loan or any payment of any other Obligations shall become
         due on a day which is not a Business Day, such payment shall be made on
         the next succeeding Business Day and, in the case of a principal
         payment, such extension of time shall be included in computing
         interest, fees and commissions in connection with such payment.

             (ii) The Applicable Floating Rate Margins, Applicable Eurocurrency
         Margins and Applicable Commitment Fee Percentage shall be determined
         from time to time by reference to the table set forth below, on the
         basis of the then applicable Leverage Ratio as described in this
         Section 2.15(D)(ii):

For purposes of this Section 2.15(D)(ii), the Leverage Ratio shall be calculated
as provided in Section 7.4(A). Upon receipt of the financial statements
delivered pursuant to Sections 7.1(A)(i) and (ii), as applicable, the Applicable
Floating Rate Margins, Applicable Eurocurrency Margins and Applicable Commitment
Fee Percentage shall be adjusted, such adjustment being effective five (5)
Business Days following the Administrative Agent's receipt of such financial
statements and the compliance certificate required to be delivered in connection
therewith pursuant to Section 7.1(A)(iii); provided, that if the Parent and the
Borrowers shall not have timely delivered their financial statements in
accordance with Section 7.1(A)(i) or (ii), as applicable, then commencing on the
date upon which such financial statements should have been delivered and
continuing until five (5) Business Days following the date such financial
statements are actually delivered, the Applicable Floating Rate Margins,
Applicable Eurocurrency Margins and Applicable Commitment Fee Percentage shall
be the Applicable Floating Rate Margins, Applicable Eurocurrency Margins and
applicable Commitment Fee Percentage corresponding to Level IV Status under the
pricing grid set forth in Section 2.15(D)(ii).

             (iii) Notwithstanding anything herein to the contrary, from the
         Closing Date until receipt of the Parent's financial statements
         delivered pursuant to Section 7.1(A)(i) for the fiscal quarter ending
         June 30, 2001, the Applicable Floating Rate Margins, Applicable
         Eurocurrency Margins and Applicable Commitment Fee Percentage shall be
         those corresponding to Level IV Status.

         (E) Taxes.

             (i) Any and all payments by the Parent (as used in this Section
         2.15(E), in its capacity as a Guarantor) and the Borrowers hereunder
         (whether in respect of principal, interest, fees or otherwise) shall be
         made free and clear of and without deduction for any and all present or
         future taxes, levies, imposts, deductions, charges or withholdings or
         any interest, penalties and liabilities with respect thereto including
         those arising after the date hereof as a result of the adoption of or
         any change in any law, treaty, rule, regulation, guideline or
         determination of a Governmental Authority or any change in the
         interpretation or application thereof by a Governmental Authority but
         excluding, in the case of each Lender and the Administrative




                                       58

         Agent, such taxes (including income taxes, franchise taxes and branch
         profit taxes) as are imposed on or measured by such Lender's or the
         Administrative Agent's, as the case may be, net income by the United
         States of America or any Governmental Authority of the jurisdiction
         under the laws of which such Lender or the Administrative Agent, as the
         case may be, is organized (all such non-excluded taxes, levies,
         imposts, deductions, charges, withholdings, and liabilities which the
         Administrative Agent or a Lender determines to be applicable to this
         Agreement, the other Loan Documents, the Revolving Loan Commitments,
         the Loans or the Letters of Credit being hereinafter referred to as
         "TAXES"). If the Parent or any Borrower shall be required by law to
         deduct or withhold any Taxes from or in respect of any sum payable
         hereunder or under the other Loan Documents to any Lender or the
         Administrative Agent, (i) the sum payable shall be increased as may be
         necessary so that after making all required deductions or withholdings
         (including deductions applicable to additional sums payable under this
         Section 2.15(E)) such Lender or Administrative Agent (as the case may
         be) receives an amount equal to the sum it would have received had no
         such deductions or withholdings been made, (ii) the Parent or the
         applicable Borrower shall make such deductions or withholdings, and
         (iii) the Parent or the applicable Borrower shall pay the full amount
         deducted or withheld to the relevant taxation authority or other
         authority in accordance with applicable law. If a withholding tax of
         the United States of America or any other Governmental Authority shall
         be or become applicable (y) after the date of this Agreement, to such
         payments by the Parent or the applicable Borrower made to the Lending
         Installation or any other office that a Lender may claim as its Lending
         Installation, or (z) after such Lender's selection and designation of
         any other Lending Installation, to such payments made to such other
         Lending Installation, such Lender shall use reasonable efforts to make,
         fund and maintain the affected Loans through another Lending
         Installation of such Lender in another jurisdiction so as to reduce the
         Parent's or the applicable Borrower's liability hereunder, if the
         making, funding or maintenance of such Loans through such other Lending
         Installation of such Lender does not, in the judgment of such Lender,
         otherwise adversely affect such Loans, or obligations under the
         Revolving Loan Commitments of such Lender.

             (ii) In addition, the Parent and the Borrowers agree to pay any
         present or future stamp or documentary taxes or any other excise or
         property taxes, charges, or similar levies which arise from any payment
         made hereunder, from the issuance of Letters of Credit hereunder, or
         from the execution, delivery or registration of, or otherwise with
         respect to, this Agreement, the other Loan Documents, the Revolving
         Loan Commitments, the Loans or the Letters of Credit (hereinafter
         referred to as "OTHER TAXES").

             (iii) Each of the Parent and each Borrower indemnifies each Lender
         and the Administrative Agent for the full amount of Taxes and Other
         Taxes (including, without limitation, any Taxes or Other Taxes imposed
         by any Governmental Authority on amounts payable under this Section
         2.15(E)) paid by such Lender or the Administrative Agent (as the case
         may be) and any liability (including penalties, interest, and expenses)
         arising therefrom or with respect thereto, whether or not such Taxes or
         Other Taxes were correctly or legally asserted. This indemnification
         shall be made within thirty (30) days after the date such Lender or the
         Administrative Agent (as the case may be) makes written demand
         therefor. If the Taxes or Other Taxes with respect to which the Parent
         or a Borrower has made either a direct payment to the taxation or other
         authority or an indemnification payment hereunder




                                       59

         are subsequently refunded to any Lender, such Lender will return to the
         Parent or the applicable Borrower, if no Event of Default has occurred
         and is continuing, an amount equal to the lesser of the indemnification
         payment or the refunded amount. A certificate as to any additional
         amount payable to any Lender or the Administrative Agent under this
         Section 2.15(E) submitted to the Parent or the applicable Borrower and
         the Administrative Agent (if a Lender is so submitting) by such Lender
         or the Administrative Agent shall show in reasonable detail the amount
         payable and the calculations used to determine such amount and shall,
         absent manifest error, be final, conclusive and binding upon all
         parties hereto. With respect to such deduction or withholding for or on
         account of any Taxes and to confirm that all such Taxes have been paid
         to the appropriate Governmental Authorities, the Parent or the
         applicable Borrower shall promptly (and in any event not later than
         thirty (30) days after receipt) furnish to each Lender and the
         Administrative Agent such certificates, receipts and other documents as
         may be required (in the reasonable judgment of such Lender or the
         Administrative Agent) to establish any tax credit to which such Lender
         or the Administrative Agent may be entitled.

             (iv) Within thirty (30) days after the date of any payment of Taxes
         or Other Taxes by the Parent or a Borrower, the Parent or the Borrowers
         shall furnish to the Administrative Agent the original or a certified
         copy of a receipt evidencing payment thereof.

             (v) Without prejudice to the survival of any other agreement of the
         Parent or the Borrowers hereunder, the agreements and obligations of
         the Parent and the Borrowers contained in this Section 2.15(E) shall
         survive the payment in full of all Obligations, the termination of the
         Letters of Credit and the termination of this Agreement.

             (vi) Each Lender (including any Replacement Lender or Purchaser)
         that is not created or organized under the laws of the United States of
         America or a political subdivision thereof (each a "NON-U.S. LENDER")
         shall deliver to SDM and the Administrative Agent on or before the
         Effective Date, or, if later, the date on which such Lender becomes a
         Lender pursuant to Section 14.3 hereof (and from time to time
         thereafter upon the request of SDM or the Administrative Agent, but
         only for so long as such Non-U.S. Lender is legally entitled to do so),
         either (1) two (2) duly completed copies of either (A) IRS Form W-8BEN,
         or (B) IRS Form W-8ECI, or in either case an applicable successor form;
         or (2) in the case of a Non-U.S. Lender that is not legally entitled to
         deliver the forms listed in clause (vi)(1), (x) a certificate of a duly
         authorized officer of such Non-U.S. Lender to the effect that such
         Non-U.S. Lender is not (A) a "bank" within the meaning of Section
         881(c)(3)(A) of the Code, (B) a "10 percent shareholder" of the Parent
         or any Borrower within the meaning of Section 881(c)(3)(B) of the Code,
         or (C) a controlled foreign corporation receiving interest from a
         related person within the meaning of Section 881(c)(3)(C) of the Code
         (such certificate, an "EXEMPTION CERTIFICATE") and (y) two (2) duly
         completed copies of IRS Form W-8BEN or applicable successor form. Each
         such Lender further agrees to deliver to SDM and the Administrative
         Agent from time to time a true and accurate certificate executed in
         duplicate by a duly authorized officer of such Lender in a form
         satisfactory to SDM and the Administrative Agent, before or promptly
         upon the occurrence of any event requiring a change in the most recent
         certificate previously delivered by it to SDM and the Administrative
         Agent pursuant to this Section 2.15(E)(vi). Further, each Lender which
         delivers a form or certificate pursuant to this clause (vi) covenants
         and agrees to deliver to




                                       60
<PAGE>   61
         SDM and the Administrative Agent within fifteen (15) days prior to the
         expiration of such form, for so long as this Agreement is still in
         effect, another such certificate and/or two (2) accurate and complete
         original newly-signed copies of the applicable form (or any successor
         form or forms required under the Code or the applicable regulations
         promulgated thereunder).

         Each Lender shall promptly furnish to SDM and the Administrative Agent
         such additional documents as may be reasonably required by the Parent
         or any Borrower or the Administrative Agent to establish any exemption
         from or reduction of any Taxes or Other Taxes required to be deducted
         or withheld and which may be obtained without undue expense to such
         Lender. Notwithstanding any other provision of this Section 2.15(E),
         neither the Parent nor any Borrower shall be obligated to gross up any
         payments to any Lender pursuant to Section 2.15(E)(i), or to indemnify
         any Lender pursuant to Section 2.15(E)(iii), in respect of United
         States federal withholding taxes to the extent imposed as a result of
         (x) the failure of such Lender to deliver to SDM the form or forms
         and/or an Exemption Certificate, as applicable to such Lender, pursuant
         to Section 2.15(E)(vi), (y) such form or forms and/or Exemption
         Certificate not establishing a complete exemption from U.S. federal
         withholding tax or the information or certifications made therein by
         the Lender being untrue or inaccurate on the date delivered in any
         material respect, or (z) the Lender designating a successor Lending
         Installation 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; provided,
         however, that the Parent or the applicable Borrower shall be obligated
         to gross up any payments to any such Lender pursuant to Section
         2.15(E)(i), and to indemnify any such Lender pursuant to Section
         2.15(E)(iii), in respect of United States federal withholding taxes if
         (x) any such failure to deliver a form or forms or an Exemption
         Certificate or the failure of such form or forms or exemption
         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, which change rendered such Lender no longer
         legally entitled to deliver such form or forms or Exemption Certificate
         or otherwise ineligible for a complete exemption from U.S. federal
         withholding tax, or rendered the information or the certifications made
         in such form or forms or Exemption Certificate untrue or inaccurate in
         any material respect, (y) the redesignation of the Lender's Lending
         Installation was made at the request of the Parent or any Borrower or
         (z) the obligation to gross up payments to any such Lender pursuant to
         Section 2.15(E)(i), or to indemnify any such Lender pursuant to Section
         2.15(E)(iii), is with respect to a Purchaser that becomes a Purchaser
         as a result of an assignment made at the request of the Parent or any
         Borrower.

             (vii) Upon the request, and at the expense of the Parent or the
         Borrowers, each Lender to which the Parent or any Borrower is required
         to pay any additional amount pursuant to this Section 2.15(E), shall
         reasonably afford the Parent or the applicable Borrower the opportunity
         to contest, and shall reasonably cooperate with the Parent or the
         applicable Borrower in contesting, the imposition of any Tax giving
         rise to such payment; provided, that (i) such Lender shall not be
         required to afford the applicable Borrower the opportunity to so
         contest unless the Parent or the applicable Borrower shall have
         confirmed in writing to such Lender its obligation to pay such amounts
         pursuant to this Agreement; and (ii) the



                                       61
<PAGE>   62

         Parent and the Borrowers shall reimburse such Lender for its reasonable
         attorneys' and accountants' fees and disbursements incurred in so
         cooperating with the Parent or the applicable Borrower in contesting
         the imposition of such Tax; provided, however, that notwithstanding the
         foregoing, no Lender shall be required to afford the Parent or any
         Borrower the opportunity to contest, or cooperate with the Parent or
         the applicable Borrower in contesting, the imposition of any Taxes, if
         such Lender in good faith determines that to do so would have an
         adverse effect on it.

         2.16. Notification of Advances, Interest Rates, Prepayments and
Aggregate Revolving Loan Commitment Reductions. Promptly after receipt thereof,
the Administrative Agent will notify each Lender of the contents of each
Aggregate Revolving Loan Commitment reduction notice, Borrowing/Election Notice,
and repayment notice received by it hereunder and will notify SDM of the
contents of each Opt-Out Notice received by it hereunder. The Administrative
Agent will notify each Lender of its decision to include a new Eligible Currency
as an Agreed Currency pursuant to clause (iii) of the definition of "Agreed
Currency" on or before the date that is one (1) Business Day prior to the date
on which the applicable Borrower has indicated to the Administrative Agent that
it intends to submit a Borrowing/Election Notice for a Loan in such Agreed
Currency. The Administrative Agent will notify the applicable Borrower and each
Lender of the interest rate and Agreed Currency applicable to each Eurocurrency
Rate Loan promptly upon determination of such interest rate and Agreed Currency
and will give each Lender prompt notice of each change in the Alternate Base
Rate.

         2.17. Lending Installations. Each Lender may book its Loans or Letters
of Credit at any Lending Installation selected by such Lender and may change its
Lending Installation from time to time. All terms of this Agreement shall apply
to any such Lending Installation. Each Lender may, by written or facsimile
notice to the Administrative Agent and the Borrowers, designate a Lending
Installation through which Loans will be made by it and for whose account Loan
payments and/or payments of L/C Obligations are to be made.

         2.18. Non-Receipt of Funds by the Administrative Agent. Unless a
Borrower or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the Administrative
Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case
of any Borrower, a payment of principal, interest or fees to the Administrative
Agent for the account of the Lenders, that it does not intend to make such
payment, the Administrative Agent may assume that such payment has been made.
The Administrative Agent may, but shall not be obligated to, make the amount of
such payment available to the intended recipient in reliance upon such
assumption. If such Lender or the applicable Borrower, as the case may be, has
not in fact made such payment to the Administrative Agent, the recipient of such
payment shall, on demand by the Administrative Agent, repay to the
Administrative Agent the amount so made available together with interest thereon
in respect of each day during the period commencing on the date such amount was
so made available by the Administrative Agent until the date the Administrative
Agent recovers such amount at a rate per annum equal to (i) in the case of
payment by a Lender, the Federal Funds Effective Rate for such day or (ii) in
the case of payment by a Borrower, the interest rate applicable to the relevant
Loan.

         2.19. Termination Date. This Agreement shall be effective until the
latest of (i) the Termination Date, (ii) the Tranche A Term Loan Termination
Date and (iii) the Tranche B Term Loan




                                       62
<PAGE>   63

Termination Date. Notwithstanding the termination of this Agreement, until (A)
all of the Secured Obligations (other than contingent indemnity obligations)
shall have been fully and indefeasibly paid and satisfied in cash, (B) all
financing arrangements among the Borrowers and the Lenders shall have been
terminated (including under Hedging Agreements or other agreements with respect
to Hedging Obligations) and (C) all of the Letters of Credit shall have expired,
been cancelled or terminated, or cash collateralized pursuant to the terms of
this Agreement or supported by a letter of credit acceptable to the
Administrative Agent (collectively, the "TERMINATION CONDITIONS"), all of the
rights and remedies under this Agreement and the other Loan Documents shall
survive and the Administrative Agent shall be entitled to retain its security
interest in and to all existing and future Collateral for the benefit of itself
and the Holders of Secured Obligations.

         2.20. Replacement of Certain Lenders. In the event a Lender ("AFFECTED
LENDER") shall have: (i) failed to fund its Applicable Pro Rata Share of any
Advance requested by the applicable Borrower, or to fund a Revolving Loan in
order to repay Swing Line Loans pursuant to Section 2.3(D), which such Lender is
obligated to fund under the terms of this Agreement and which failure has not
been cured, (ii) requested compensation from any Borrower under Sections
2.15(E), 4.1 or 4.2 to recover Taxes, Other Taxes or other additional costs
incurred by such Lender which are not being incurred generally by the other
Lenders except as provided under any applicable Alternate Currency Addendum,
(iii) delivered a notice pursuant to Section 4.3 claiming that such Lender is
unable to extend Eurocurrency Rate Loans to any Borrower for reasons not
generally applicable to the other Lenders (it being understood that prior
delivery of an Opt-Out Notice shall not constitute a notice under this clause
(iii)) or (iv) has invoked Section 11.2; then, in any such case, after
engagement of one or more "Replacement Lenders" (as defined below) by the
Borrowers and/or the Administrative Agent, the Borrowers or the Administrative
Agent may make written demand on such Affected Lender (with a copy to the
Administrative Agent in the case of a demand by the Borrowers and a copy to the
Borrowers in the case of a demand by the Administrative Agent) for the Affected
Lender to assign, and such Affected Lender shall use commercially reasonable
efforts to assign pursuant to one or more duly executed Assignment Agreements
five (5) Business Days after the date of such demand, to one or more financial
institutions that comply with the provisions of Section 14.3(A) which the
Borrowers or the Administrative Agent, as the case may be, shall have engaged
for such purpose ("REPLACEMENT LENDER"), all of such Affected Lender's rights
and obligations under this Agreement and the other Loan Documents (including,
without limitation, its Revolving Loan Commitment, all Loans owing to it, all of
its participation interests in existing Letters of Credit, L/C Drafts and
unreimbursed drawings under Letters of Credit, and its obligation to participate
in additional Letters of Credit and Swing Line Loans hereunder) in accordance
with Section 14.3. The Administrative Agent agrees, upon the occurrence of such
events with respect to an Affected Lender and upon the written request of the
Borrowers, to use its reasonable efforts to obtain the commitments from one or
more financial institutions to act as a Replacement Lender. The Administrative
Agent is authorized to execute one or more of such assignment agreements as
attorney-in-fact for any Affected Lender failing to execute and deliver the same
within five (5) Business Days after the date of such demand. Further, with
respect to such assignment the Affected Lender shall have concurrently received,
in cash, all amounts due and owing to the Affected Lender hereunder or under any
other Loan Document, including, without limitation, the aggregate outstanding
principal amount of the Loans owed to such Lender, together with accrued
interest thereon through the date of such assignment, amounts payable under
Sections 2.15(E), 4.1, and 4.2 with respect to such Affected Lender and
compensation payable under Section 2.15(C) in the event of any replacement of
any Affected Lender under clause (ii) or clause (iii) of this Section 2.20;





                                       63
<PAGE>   64

provided that upon such Affected Lender's replacement, such Affected Lender
shall cease to be a party hereto but shall continue to be entitled to the
benefits of Sections 2.15(E), 4.1, 4.2, 4.4, and 11.7, as well as to any fees
accrued for its account hereunder and not yet paid, and shall continue to be
obligated under Section 12.8. Upon the replacement of any Affected Lender
pursuant to this Section 2.20, the provisions of Section 9.2 shall continue to
apply with respect to Loans which are then outstanding with respect to which the
Affected Lender failed to fund its Applicable Pro Rata Share and which failure
has not been cured.

         2.21. Judgment Currency. If, for the purposes of obtaining judgment in
any court, it is necessary to convert a sum due from any Borrower hereunder in
the currency expressed to be payable herein (the "SPECIFIED CURRENCY") into
another currency, the parties hereto agree, to the fullest extent that they may
effectively do so, that the rate of exchange used shall be that at which in
accordance with normal banking procedures the Administrative Agent could
purchase the specified currency with such other currency at the Administrative
Agent's main office in the applicable local jurisdiction on the Business Day
preceding that on which the final, non-appealable judgment is given. The
obligations of each Borrower in respect of any sum due to any Lender or the
Administrative Agent hereunder shall, notwithstanding any judgment in a currency
other than the specified currency, be discharged only to the extent that on the
Business Day following receipt by such Lender or the Administrative Agent (as
the case may be) of any sum adjudged to be so due in such other currency such
Lender or the Administrative Agent (as the case may be) may in accordance with
normal, reasonable banking procedures purchase the specified currency with such
other currency. If the amount of the specified currency so purchased is less
than the sum originally due to such Lender or the Administrative Agent, as the
case may be, in the specified currency, each Borrower agrees, to the fullest
extent that it may effectively do so, as a separate obligation and
notwithstanding any such judgment, to indemnify such Lender or the
Administrative Agent, as the case may be, against such loss, and if the amount
of the specified currency so purchased exceeds (a) the sum originally due to any
Lender or the Administrative Agent, as the case may be, in the specified
currency and (b) any amounts shared with other Lenders as a result of
allocations of such excess as a disproportionate payment to such Lender under
Section 14.2, such Lender or the Administrative Agent, as the case may be,
agrees to remit such excess to such Borrower.

         2.22. Market Disruption; Denomination of Amounts in Dollars; Dollar
Equivalent of Reimbursement Obligations.

         (A) Market Disruption. Notwithstanding the satisfaction of all
conditions referred to in this Article II with respect to any Advance in any
Agreed Currency other than Dollars or in any Alternate Currency, as applicable,
if there shall occur on or prior to the date of such Advance any change in
national or international financial, political or economic conditions or
currency exchange rates or exchange controls which would in the reasonable
opinion of any Borrower, the Administrative Agent, the Required Lenders (if such
change is with respect to an Agreed Currency) and the Swing Line Bank (if such
change is with respect to an Alternate Currency) make it impracticable for the
Eurocurrency Rate Loans or Alternate Currency Swing Line Loans comprising such
Advance to be denominated in the Agreed Currency or Alternate Currency, as
applicable, specified by the applicable Borrower, then the Administrative Agent
shall forthwith give notice thereof to such Borrower, the Lenders (with respect
to any Agreed Currency) and the Swing Line Bank (with respect to any Alternate
Currency), or the applicable Borrower shall give notice to the Administrative
Agent, the Lenders (with respect to any Agreed Currency) and the Swing Line Bank




                                       64
<PAGE>   65

(with respect to any Alternate Currency), as the case may be, and such
Eurocurrency Rate Loans or Alternate Currency Swing Line Loans shall not be
denominated in such currency but shall be made on such Borrowing Date in
Dollars, in an aggregate principal amount equal to the Dollar Amount of the
aggregate principal amount specified in the related Borrowing Notice, as
Floating Rate Loans, unless the applicable Borrower notifies the Administrative
Agent at least one (1) Business Day before such date that (i) it elects not to
borrow on such date or (ii) it elects to borrow on such date in a different
Agreed Currency or Alternate Currency, as the case may be, in which the
denomination of such Loans would in the opinion of the Administrative Agent, the
Required Lenders or the Swing Line Bank, as applicable, be practicable and in an
aggregate principal amount equal to the Dollar Amount of the aggregate principal
amount specified in the related Borrowing Notice.

         (B) Calculation of Amounts. Except as set forth in Sections 2.2, 2.3
and 2.5, all amounts referenced in this Article II shall be calculated using the
Dollar Amount determined based upon the Equivalent Amount in effect as of the
date of any determination thereof; provided, however, to the extent that any
Borrower shall be obligated hereunder to pay in Dollars any Advance denominated
in a currency other than Dollars, such amount shall be paid in Dollars using the
Dollar Amount of the Advance (calculated based upon the Equivalent Amount in
effect on the date of payment thereof) and in the event that the applicable
Borrower does not reimburse the Administrative Agent and the Lenders are
required to fund a purchase of a participation in such Advance, such purchase
shall be made in Dollars in an amount equal to the Dollar Amount of such Advance
(calculated based upon the Equivalent Amount in effect on the date of payment
thereof). Notwithstanding anything herein to the contrary, the full risk of
currency fluctuations shall be borne by the Borrowers and the Borrowers agree to
indemnify and hold harmless the Issuing Bank, the Swing Line Bank, the
Administrative Agent and the Lenders from and against any loss resulting from
any borrowing denominated in a currency other than in Dollars and for which the
Lenders are not reimbursed on the day of such borrowing and the payment in
Dollars of any Loan or other Obligations denominated in a currency other than
Dollars.

         2.23. Election to Opt Out of Eurocurrency Advances by Certain Lenders.
To the extent not specifically addressed in this Article II, notwithstanding any
of the foregoing provisions of this Article II to the contrary permitting a
Borrower to request Eurocurrency Rate Loans or to convert Floating Rate Loans
into Eurocurrency Rate Loans in Agreed Currencies other than Dollars, no Lender
shall be required to fund Eurocurrency Rate Loans for any Agreed Currency for
which such Lender has timely delivered an Opt-Out Notice to the Administrative
Agent (as set forth in the definition of "Opt-Out Notice"). Following the
Administrative Agent's receipt of a Borrowing/Election Notice from SDM for
Eurocurrency Rate Advances where the basis for such Advance is the applicable
Opt-Out Currency, such Lender shall fund its Revolving Loan Pro Rata Share of
such Eurocurrency Rate Advance in Dollars as an Opt-Out Loan, which shall bear
interest at the Opt-Out Rate. Any borrowing hereunder consisting of both
Eurocurrency Rate Loans and Opt-Out Loans made to an applicable Borrower shall
be treated as a single "Eurocurrency Rate Advance" notwithstanding that a
portion of such Advance shall be made as Opt-Out Loans, and the terms and
provisions governing Eurocurrency Rate Advances hereunder shall apply equally to
the Eurocurrency Rate Loans and the Opt-Out Loans that comprise such Advance.
For purposes of clarification, the Dollar Amount of the Eurocurrency Rate
Advance requested by the Borrower (and not the Dollar Amount of the Eurocurrency
Rate Loans made by the Lenders pursuant to such Request) shall be considered in
determining (i) whether the aggregate outstanding principal Dollar Amount of all
Eurocurrency Rate Advances in Agreed Currencies other than Dollars exceed the




                                       65
<PAGE>   66

Maximum Non-Eurodollar Eurocurrency Amount at any time or (ii) whether any
minimum borrowing or prepayment Dollar Amount thresholds set forth in this
Article II have been satisfied.

                   ARTICLE III: THE LETTER OF CREDIT FACILITY

         3.1. Obligation to Issue Letters of Credit. Subject to the terms and
conditions of this Agreement and in reliance upon the representations,
warranties and covenants of the Borrowers herein set forth, the Issuing Bank
hereby agrees to issue for the account of SDM through such Issuing Bank's
branches as it and SDM may jointly agree, one or more Letters of Credit
denominated in Dollars in accordance with this Article III, from time to time
during the period, commencing on the Closing Date and ending on the Business Day
prior to the Termination Date.

         3.2. [Intentionally Omitted.]

         3.3. Types and Amounts. The Issuing Bank shall not have any obligation
to and shall not:

              (i) issue (or amend) any Letter of Credit if on the date of
         issuance (or amendment), before or after giving effect to the Letter of
         Credit requested hereunder, (a) the Dollar Amount of the Revolving
         Credit Obligations at such time would exceed the Aggregate Revolving
         Loan Commitment at such time, or (b) the aggregate outstanding amount
         of the L/C Obligations would exceed $20,000,000, calculated as of the
         date of issuance of any Letter of Credit; or

              (ii) issue (or amend) any Letter of Credit which has an expiration
         date later than the date which is the earlier of (x) one (1) year after
         the date of issuance thereof or (y) five (5) Business Days immediately
         preceding the Termination Date; provided, that any Letter of Credit
         with a one year tenor may provide for the renewal thereof for
         additional one year periods (which in no event shall extend beyond the
         date referred to in clause (y) above.

         3.4. Conditions. In addition to being subject to the satisfaction of
the conditions contained in Sections 5.1, 5.2 and 5.3, the obligation of the
Issuing Bank to issue any Letter of Credit is subject to the satisfaction in
full of the following conditions:

              (i) SDM shall have delivered to the Issuing Bank (at such times
         and in such manner as such Issuing Bank may reasonably prescribe) and
         the Administrative Agent, a request for issuance of such Letter of
         Credit in substantially the form of Exhibit C hereto (each such request
         a "REQUEST FOR LETTER OF CREDIT"), duly executed applications for such
         Letter of Credit, and such other documents, instructions and agreements
         as may be required pursuant to the terms thereof (all such
         applications, documents, instructions, and agreements being referred to
         herein as the "L/C DOCUMENTS"), and the proposed Letter of Credit shall
         be reasonably satisfactory to such Issuing Bank as to form and content;
         and

              (ii) as of the date of issuance no order, judgment or decree of
         any court, arbitrator or Governmental Authority shall purport by its
         terms to enjoin or restrain the Issuing Bank from issuing such Letter
         of Credit and no law, rule or regulation applicable to such Issuing
         Bank and no request or directive (whether or not having the force of
         law) from a Governmental




                                       66
<PAGE>   67

         Authority with jurisdiction over such Issuing Bank shall prohibit or
         request that such Issuing Bank refrain from the issuance of Letters of
         Credit generally or the issuance of that Letter of Credit.

         3.5. Procedure for Issuance of Letters of Credit.

         (A) Issuance. Subject to the terms and conditions of this Article III
and provided that the applicable conditions set forth in Sections 5.1, 5.2 and
5.3 hereof have been satisfied, the Issuing Bank shall, on the requested date,
issue a Letter of Credit on behalf of SDM in accordance with such Issuing Bank's
usual and customary business practices and, in this connection, such Issuing
Bank may assume that the applicable conditions set forth in Section 5.3 hereof
have been satisfied unless it shall have received notice to the contrary from
the Administrative Agent or a Lender or has knowledge that the applicable
conditions have not been met.

         (B) Notice. The Issuing Bank shall give the Administrative Agent
written or telex notice, or telephonic notice confirmed promptly thereafter in
writing, of the issuance of a Letter of Credit, provided, however, that the
failure to provide such notice shall not result in any liability on the part of
such Issuing Bank.

         (C) No Amendment. The Issuing Bank shall not extend or amend any Letter
of Credit unless the requirements of this Section 3.5 are met as though a new
Letter of Credit was being requested and issued.

         3.6. Letter of Credit Participation. Immediately upon the issuance of
each Letter of Credit hereunder, each Lender with a Revolving Loan Pro Rata
Share shall be deemed to have automatically, irrevocably and unconditionally
purchased and received from the Issuing Bank an undivided interest and
participation in and to such Letter of Credit, the obligations of the applicable
Borrower in respect thereof, and the liability of such Issuing Bank thereunder
(collectively, an "L/C INTEREST") in the amount available for drawing under such
Letter of Credit multiplied by such Lender's Revolving Loan Pro Rata Share. The
Issuing Bank will notify each Lender promptly upon presentation to it of an L/C
Draft or upon any other draw under a Letter of Credit. On or before the Business
Day on which the Issuing Bank makes payment of each such L/C Draft or, in the
case of any other draw on a Letter of Credit, on demand by the Administrative
Agent or the Issuing Bank, each Lender shall make payment to the Administrative
Agent, for the account of the Issuing Bank, in immediately available funds in an
amount equal to such Lender's Revolving Loan Pro Rata Share of such payment or
draw. The obligation of each Lender to reimburse the Issuing Bank under this
Section 3.6 shall be unconditional, continuing, irrevocable and absolute. In the
event that any Lender fails to make payment to the Administrative Agent of any
amount due under this Section 3.6, the Administrative Agent shall be entitled to
receive, retain and apply against such obligation the principal and interest
otherwise payable to such Lender hereunder until the Administrative Agent
receives such payment from such Lender or such obligation is otherwise fully
satisfied; provided, however, that nothing contained in this sentence shall
relieve such Lender of its obligation to reimburse the Issuing Bank for such
amount in accordance with this Section 3.6.

         3.7. Reimbursement Obligation. SDM agrees unconditionally, irrevocably
and absolutely to pay immediately to the Administrative Agent, for the account
of the Lenders, the amount of each advance drawn under or pursuant to a Letter
of Credit or an L/C Draft related thereto (such




                                       67
<PAGE>   68

obligation of SDM to reimburse the Administrative Agent for an advance made
under a Letter of Credit or L/C Draft being hereinafter referred to as a
"REIMBURSEMENT OBLIGATION" with respect to such Letter of Credit or L/C Draft),
each such reimbursement to be made by SDM no later than the Business Day on
which the Issuing Bank makes payment of each such L/C Draft or, if SDM shall
have received notice of a Reimbursement Obligation later than 12:00 p.m.
(Chicago time), on any Business Day or on a day which is not a Business Day, no
later than 12:00 p.m. (Chicago time), on the immediately following Business Day
or, in the case of any other draw on a Letter of Credit, the date specified in
the demand of such Issuing Bank. If SDM at any time fails to repay a
Reimbursement Obligation pursuant to this Section 3.7, SDM shall be deemed to
have elected to borrow Revolving Loans from the Lenders, as of the date of the
advance giving rise to the Reimbursement Obligation, equal in amount to the
unpaid Reimbursement Obligation. Such Revolving Loans shall be made as of the
date of the payment giving rise to such Reimbursement Obligation, automatically,
without notice and without any requirement to satisfy the conditions precedent
otherwise applicable to an Advance of Revolving Loans. Such Revolving Loans
shall constitute a Floating Rate Advance, the proceeds of which Advance shall be
used to repay such Reimbursement Obligation. If, for any reason, SDM fails to
repay a Reimbursement Obligation on the day such Reimbursement Obligation arises
and, for any reason, the Lenders are unable to make or have no obligation to
make Revolving Loans, then such Reimbursement Obligation shall bear interest
from and after such day, until paid in full, at the interest rate applicable to
a Floating Rate Advance.

         3.8. Letter of Credit Fees. The Borrowers agree to pay:

              (i) quarterly, in arrears, to the Administrative Agent for the
         ratable benefit of the Lenders, except as set forth in Section 9.2, a
         letter of credit fee at a rate per annum equal to the Applicable L/C
         Fee Percentage on the average daily outstanding amount available for
         drawing under all Letters of Credit;

              (ii) quarterly, in arrears, to the Issuing Bank, a letter of
         credit fronting fee equal to 0.25% per annum on the average daily
         outstanding stated amount available for drawing under all Letters of
         Credit issued by such Issuing Bank; and

              (iii) to the Issuing Bank, all customary fees and other issuance,
         amendment, cancellation, document examination, negotiation, transfer
         and presentment expenses and related charges in connection with the
         issuance, amendment, cancellation, presentation of L/C Drafts,
         negotiation, transfer and the like customarily charged by such Issuing
         Bank with respect to standby Letters of Credit, payable at the time of
         invoice of such amounts.

         3.9. Issuing Bank Reporting Requirements. In addition to the notices
required by Section 3.5(B), the Issuing Bank shall, no later than the tenth
Business Day following the last day of each month, provide to the Administrative
Agent, upon the Administrative Agent's request, schedules, in form and substance
reasonably satisfactory to the Administrative Agent, showing the date of issue,
account party, expiration date and the reference number of each Letter of Credit
issued by it outstanding at any time during such month and the aggregate amount
payable by SDM during such month. In addition, upon the request of the
Administrative Agent, the Issuing Bank shall furnish to the Administrative Agent
copies of any Letter of Credit and any application for or reimbursement
agreement with respect to a Letter of Credit to which the Issuing Bank is party
and such other




                                       68
<PAGE>   69

documentation as may reasonably be requested by the Administrative Agent. Upon
the request of any Lender, the Administrative Agent will promptly provide to
such Lender information concerning such Letters of Credit.

         3.10. Indemnification; Exoneration.

         (A) Indemnification. In addition to amounts payable as elsewhere
provided in this Article III, the Parent and each Borrower hereby agrees to
protect, indemnify, pay and save harmless the Administrative Agent, each Issuing
Bank and each Lender from and against any and all liabilities and costs which
the Administrative Agent, such Issuing Bank or such Lender may incur or be
subject to as a consequence, direct or indirect, of (i) the issuance of any
Letter of Credit other than, in the case of the Issuing Bank, as a result of its
Gross Negligence or willful misconduct, as determined by the final judgment of a
court of competent jurisdiction, or (ii) the failure of the Issuing Bank to
honor a drawing under a Letter of Credit as a result of any act or omission,
whether rightful or wrongful, of any present or future de jure or de facto
Governmental Authority (all such acts or omissions herein called "GOVERNMENTAL
ACTS").

         (B) Risk Assumption. As among the Borrowers, the Lenders, the
Administrative Agent and the Issuing Bank, the Borrowers assume all risks of the
acts and omissions of, or misuse of such Letter of Credit by, the beneficiary of
any Letters of Credit. In furtherance and not in limitation of the foregoing,
subject to the provisions of the Letter of Credit applications and Letter of
Credit reimbursement agreements executed by SDM at the time of request for any
Letter of Credit, neither the Administrative Agent, the Issuing Bank nor any
Lender shall be responsible (in the absence of Gross Negligence or willful
misconduct in connection therewith, as determined by the final judgment of a
court of competent jurisdiction): (i) for the form, validity, sufficiency,
accuracy, genuineness or legal effect of any document submitted by any party in
connection with the application for and issuance of the Letters of Credit, even
if it should in fact prove to be in any or all respects invalid, insufficient,
inaccurate, fraudulent or forged; (ii) for the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign a
Letter of Credit or the rights or benefits thereunder or proceeds thereof, in
whole or in part, which may prove to be invalid or ineffective for any reason;
(iii) for failure of the beneficiary of a Letter of Credit to comply duly with
conditions required in order to draw upon such Letter of Credit; (iv) for
errors, omissions, interruptions or delays in transmission or delivery of any
messages, by mail, cable, telegraph, telex, or other similar form of
teletransmission or otherwise; (v) for errors in interpretation of technical
trade terms; (vi) for any loss or delay in the transmission or otherwise of any
document required in order to make a drawing under any Letter of Credit or of
the proceeds thereof; (vii) for the misapplication by the beneficiary of a
Letter of Credit of the proceeds of any drawing under such Letter of Credit; and
(viii) for any consequences arising from causes beyond the control of the
Administrative Agent, the Issuing Bank and the Lenders, including, without
limitation, any Governmental Acts. None of the above shall affect, impair, or
prevent the vesting of the Issuing Bank's rights or powers under this Section
3.10.

         (C) No Liability. In furtherance and extension and not in limitation of
the specific provisions hereinabove set forth, any action taken or omitted by
the Issuing Bank under or in connection with the Letters of Credit or any
related certificates shall not, in the absence of Gross Negligence or willful
misconduct, as determined by the final judgment of a court of competent
jurisdiction, put the Issuing Bank, the Administrative Agent or any Lender under
any resulting liability to any Borrower or relieve any Borrower of any of its
obligations hereunder to any such Person.



                                       69
<PAGE>   70

         (D) Survival of Agreements and Obligations. Without prejudice to the
survival of any other agreement of the Borrowers hereunder, the agreements and
obligations of the Borrowers contained in this Section 3.10 shall survive the
payment in full of principal and interest hereunder, the termination of the
Letters of Credit and the termination of this Agreement.

         3.11. Cash Collateral. Notwithstanding anything to the contrary herein
or in any application for a Letter of Credit, after the occurrence and during
the continuance of a Default, SDM shall, on the Business Day that it receives
Administrative Agent's demand, deliver to the Administrative Agent for the
benefit of the Lenders and the Issuing Bank, cash, or other collateral of a type
satisfactory to the Required Lenders, having a value, as determined by such
Lenders, equal to the aggregate amount of the outstanding L/C Obligations. In
addition, if the Revolving Credit Availability is at any time less than the
amount of all contingent L/C Obligations outstanding at any time, SDM shall
deposit cash collateral with the Administrative Agent in Dollars in an amount
equal to the amount by which such L/C Obligations exceed such Revolving Credit
Availability. Any such collateral shall be held by the Administrative Agent in a
separate account appropriately designated as a cash collateral account in
relation to this Agreement and the Letters of Credit and retained by the
Administrative Agent for the benefit of the Lenders and the Issuing Bank as
collateral security for the Borrowers' obligations in respect of this Agreement
and each of the Letters of Credit and L/C Drafts. Such amounts shall be applied
to reimburse the Issuing Bank for drawings or payments under or pursuant to
Letters of Credit or L/C Drafts, or if no such reimbursement is required, to
payment of such of the other Obligations as the Administrative Agent shall
determine. If no Default shall be continuing, amounts remaining in any cash
collateral account established pursuant to this Section 3.11 which are not to be
applied to reimburse the Issuing Bank for amounts actually paid or to be paid by
such Issuing Bank in respect of a Letter of Credit or L/C Draft, shall be
returned to SDM, after deduction of the Administrative Agent's expenses incurred
in connection with such cash collateral account.

                      ARTICLE IV: CHANGE IN CIRCUMSTANCES

         4.1. Yield Protection. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law) adopted after the date of this Agreement and having
general applicability to all banks within the jurisdiction in which such Lender
operates (excluding, for the avoidance of doubt, the effect of and phasing in of
capital requirements or other regulations or guidelines passed prior to the date
of this Agreement), or any interpretation or application thereof by any
Governmental Authority charged with the interpretation or application thereof,
or the compliance of any Lender therewith,

              (i) subjects any Lender or any applicable Lending Installation to
         any tax, duty, charge or withholding on or from payments due from any
         Borrower (excluding taxation of the overall net income of any Lender or
         taxation of a similar basis, which are governed by Section 2.15(E)), or
         changes the basis of taxation of payments to any Lender in respect of
         its Revolving Loan Commitment, Loans, its L/C Interests, the Letters of
         Credit or other amounts due it hereunder, or



                                       70
<PAGE>   71

              (ii) imposes or increases or deems applicable any reserve,
         assessment, insurance charge, special deposit or similar requirement
         against assets of, deposits with or for the account of, or credit
         extended by, any Lender or any applicable Lending Installation (other
         than reserves and assessments taken into account in determining the
         interest rate applicable to Eurocurrency Rate Loans) with respect to
         its Revolving Loan Commitment, Loans, L/C Interests or the Letters of
         Credit, or

              (iii) imposes any other condition the result of which is to
         increase the cost to any Lender or any applicable Lending Installation
         of making, funding or maintaining its Revolving Loan Commitment, the
         Loans, the L/C Interests or the Letters of Credit or reduces any amount
         receivable by any Lender or any applicable Lending Installation in
         connection with its Revolving Loan Commitment, Loans or Letters of
         Credit, or requires any Lender or any applicable Lending Installation
         to make any payment calculated by reference to the amount of Revolving
         Loan Commitment, Loans or L/C Interests held or interest received by it
         or by reference to the Letters of Credit, by an amount deemed material
         by such Lender;

and the result of any of the foregoing is to increase the cost to that Lender of
making, renewing or maintaining its Revolving Loan Commitment, Loans, L/C
Interests, or Letters of Credit or to reduce any amount received under this
Agreement, then, within fifteen (15) days after receipt by any Borrower of
written demand by such Lender pursuant to Section 4.5, the applicable Borrower
shall pay such Lender that portion of such increased expense incurred or
reduction in an amount received which such Lender reasonably determines is
attributable to making, funding and maintaining its Loans, L/C Interests,
Letters of Credit and its Revolving Loan Commitment.

         4.2. Changes in Capital Adequacy Regulations. If a Lender determines
(i) the amount of capital required or expected to be maintained by such Lender,
any Lending Installation of such Lender or any corporation controlling such
Lender is increased as a result of a "Change" (as defined below), and (ii) such
increase in capital will result in an increase in the cost to such Lender of
maintaining its Revolving Loan Commitment, Loans, L/C Interests, the Letters of
Credit or its obligation to make Loans hereunder, then, within fifteen (15) days
after receipt by any Borrower of written demand by such Lender pursuant to
Section 4.5, the applicable Borrower shall pay such Lender the amount necessary
to compensate for any shortfall in the rate of return on the portion of such
increased capital which such Lender reasonably determines is attributable to
this Agreement, its Revolving Loan Commitment, its Loans, its L/C Interests, the
Letters of Credit or its obligation to make Loans hereunder (after taking into
account such Lender's policies as to capital adequacy). "CHANGE" means (i) any
change after the date of this Agreement in the "Risk-Based Capital Guidelines"
(as defined below) excluding, for the avoidance of doubt, the effect of any
phasing in of such Risk-Based Capital Guidelines or any other capital
requirements passed prior to the date hereof, or (ii) any adoption of or change
in any other law, governmental or quasi-governmental rule, regulation, policy,
guideline, interpretation, or directive (whether or not having the force of law)
after the date of this Agreement which affects the amount of capital required or
expected to be maintained by any Lender or any Lending Installation or any
corporation controlling any Lender. "RISK-BASED CAPITAL GUIDELINES" means (i)
the risk-based capital guidelines in effect in the United States on the date of
this Agreement, including transition rules, and (ii) the corresponding capital
regulations promulgated by regulatory authorities outside the United States
implementing the July 1988 report of the Basle Committee on Banking Regulation
and Supervisory Practices Entitled "International Convergence of Capital
Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of this Agreement.



                                       71
<PAGE>   72

         4.3. Illegality; Availability of Types of Advances. If (i) any Lender
determines that maintenance of its Eurocurrency Rate Loans at a suitable Lending
Installation would violate any applicable law, rule, regulation or directive,
whether or not having the force of law, or (ii) the Required Lenders determine
that (x) deposits of a type, currency or maturity appropriate to match fund
Eurocurrency Rate Loans are not available or (y) the interest rate applicable to
a Eurocurrency Rate Loan does not accurately reflect the cost of making or
maintaining such an Advance, then the Administrative Agent shall suspend the
availability of the affected Type of Advance and, in the case of any occurrence
set forth in clause (i), require any Advances of the affected Type to be repaid
or converted into another Type.

         4.4. Funding Indemnification. Subject to Sections 2.5(B)(i), (ii), and
(iii), if any payment of a Eurocurrency Rate Loan occurs on a date which is not
the last day of the applicable Interest Period, whether because of acceleration,
prepayment, or otherwise, or a Eurocurrency Rate Loan is not made on the date
specified by the applicable Borrower for any reason other than default by the
Lenders, or a Eurocurrency Rate Loan is not prepaid on the date specified by the
applicable Borrower for any reason other than default by the Lenders, the
Borrowers indemnify each Lender for any loss or cost incurred by it resulting
therefrom, including, without limitation, any loss or cost in liquidating or
employing deposits acquired to fund or maintain the Eurocurrency Rate Loan. In
connection with any assignment by any Lender of any portion of the Tranche B
Term Loans made pursuant to Section 14.3 and made during the Syndication Period,
and if, notwithstanding the provisions of Section 2.4, any Borrower has
requested and the Administrative Agent has consented to the use of the
Eurocurrency Rate, such Borrower shall be deemed to have repaid all outstanding
Eurocurrency Rate Advances of such Lender as of the effective date of such
assignment and reborrowed such amount as a Floating Rate Advance and/or
Eurocurrency Rate Advance (chosen in accordance with the provisions of Section
2.4) and the indemnification provisions under this Section 4.4 shall apply.

         4.5. Lender Statements; Survival of Indemnity. If reasonably possible,
each Lender shall designate an alternate Lending Installation with respect to
its Eurocurrency Rate Loan to reduce any liability of any Borrower to such
Lender under Sections 4.1 and 4.2 or to avoid the unavailability of a Type of
Advance under Section 4.3, so long as such designation is not, in the judgment
of the Lender, disadvantageous to such Lender. Each Lender shall deliver a
written statement of such Lender to SDM (with a copy to the Administrative
Agent) as to the amount due, if any, under Section 2.15(E), 4.1, 4.2 or 4.4 and
shall set forth in reasonable detail the calculations upon which such Lender
determined such amount and shall be final, conclusive and binding on the
Borrowers in the absence of manifest error. Determination of amounts payable
under such Sections in connection with a Eurocurrency Rate Loan shall be
calculated as though each Lender funded its Eurocurrency Rate Loan through the
purchase of a deposit of the type, currency and maturity corresponding to the
deposit used as a reference in determining the Eurocurrency Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the applicable Borrower of such statement.
The obligations of the other Borrowers under Sections 2.15(E), 4.1, 4.2 and 4.4
shall survive payment of the Obligations and termination of this Agreement.

         4.6. Usury. All agreements between the Borrowers and the Administrative
Agent and the Lenders are hereby expressly limited so that in no contingency or
event whatsoever, whether by reason of acceleration of maturity of the
Indebtedness evidenced hereby or otherwise, shall the amount paid or agreed to
be paid to the Lenders for the use or the forbearance of the Indebtedness




                                       72
<PAGE>   73

evidenced hereby exceed the maximum permissible under applicable law. As used
herein, the term shall mean the law in effect as of the date hereof; provided,
however, that in the event there is a change in the law which results in a
higher permissible rate of interest, then this Agreement, any promissory note
evidencing the Revolving Loans, the Swing Line Loans, the Tranche A Term Loans
and/or the Tranche B Term Loans shall be governed by such new law as of its
effective date. In this regard, it is expressly agreed that it is the intent of
the Borrowers, the Administrative Agent and the Lenders in the execution,
delivery and acceptance of any of the above-described promissory notes to
contract in strict compliance with the laws of the State of Illinois from time
to time in effect. If, under or from any circumstances whatsoever, fulfillment
of any provision hereof or of any of the Loan Documents executed in connection
herewith or of any Collateral Documents at the time performance of such
provision shall be due, shall involve transcending the limit of validity
prescribed by applicable law, then the obligation to be fulfilled shall
automatically be reduced to the limit of such validity, and if under or from any
circumstances whatsoever any Lender should ever receive as interest an amount
which would exceed the highest lawful rate, such amount which would be excessive
interest shall be applied to the reduction of the principal balance evidenced by
the applicable promissory note and not to the payment of interest. This
provision shall control every other provision of all Loan Documents among the
Borrowers, the Administrative Agent and the Lenders.

                        ARTICLE V: CONDITIONS PRECEDENT

         5.1. Initial Advances and Letters of Credit. The Lenders shall not be

               transactions contemplated by the Transaction Documents or any

               jurisdiction where filings are required by the Swing Line Bank or
               the applicable Borrower so that the Swing Line Bank will be
               entitled to receive payments under the Loan Documents without
               deduction or withholding of any taxes, the Administrative Agent
               shall have received originals and/or copies, as applicable, of
               all such filings required to be made and such other evidence as
               the Administrative Agent may require establishing to the
               Administrative Agent's satisfaction that the Swing Line Bank is
               entitled to receive payments under the Loan Documents without any
               such deduction or withholding of taxes or with such deductions

               Administrative Agent.

         5.3. Each Advance and Letter of Credit. The Lenders shall not be
required to make any Advance, or convert or continue any Advance, or issue any
Letter of Credit and no Swing Line Bank shall be required to make any Swing Line
Loans hereunder, unless on the applicable Borrowing Date, or in the case of a
Letter of Credit, the date on which the Letter of Credit is to be issued:

         (A) No Defaults. There exists no Default or Unmatured Default (both
before and after giving effect to such Advance or issuance);

(B) Representations and Warranties. All of the representations and warranties
contained in Article VI are true and correct as of such Borrowing Date (unless
such representation and warranty is made as of a specific date, in which case,

except for changes in the Schedules to this Agreement reflecting transactions
permitted by or not in violation of this Agreement; and

         (C) Aggregate Revolving Loan Commitment; Maximum Non-Eurodollar
Eurocurrency Amount. (i) The Revolving Credit Obligations do not, and after
making such proposed Advance or issuing such Letter of Credit would not, exceed
the Aggregate Revolving Loan Commitment, and (ii) the aggregate outstanding
principal Dollar Amount of all Advances requested in Agreed Currencies other
than Dollars does not and would not exceed the Maximum Non-Eurodollar
Eurocurrency Amount.

Each Borrowing/Election Notice with respect to each such Advance and the letter
of credit application with respect to each Letter of Credit shall constitute a
representation and warranty by the Borrowers that the conditions contained in
Sections 5.3(A), (B) and (C) have been satisfied. Any Lender may require a duly
completed officer's certificate in substantially the form of Exhibit G hereto
and/or a duly completed compliance certificate in substantially the form of
Exhibit H hereto as a condition to making an Advance.

                   ARTICLE VI: REPRESENTATIONS AND WARRANTIES

         In order to induce the Administrative Agent and the Lenders to enter
into this Agreement and to make the Loans and the other financial accommodations
to the Borrowers and to



                                       77
<PAGE>   78

issue the Letters of Credit described herein, the Parent and the Borrowers
represent and warrant as follows to each Lender and the Administrative Agent as
of the Closing Date, on the Initial Adjustment Date, on the Final Adjustment
Date and on the Opening Balance Sheet Delivery Date (in each case, as of the
Closing Date, taking into account the post-closing adjustments as of such later
date), giving effect to the consummation of the transactions contemplated by the
Transaction Documents on the Closing Date, and thereafter on each date as
required by Section 5.2 and 5.3.

         6.1. Organization; Corporate Powers. The Parent and each of its
Subsidiaries (i) is a corporation, limited liability company or partnership duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its organization, (ii) is duly qualified to do business as a
foreign entity and is in good standing under the laws of each jurisdiction in
which failure to be so qualified and in good standing could reasonably be
expected to have a Material Adverse Effect, and (iii) has all requisite power
and authority to own, operate and encumber its property and to conduct its
business as presently conducted and as proposed to be conducted.

         6.2. Authority, Execution and Delivery; Transaction Documents.

         (A) Power and Authority. The Parent and each of its Subsidiaries has
the requisite power and authority (i) to execute, deliver and perform each of
the Transaction Documents which are to be executed by it in connection with the
Spin-Off Transactions or which have been executed by it as required by this
Agreement and the other Loan Documents and (ii) to file the Transaction
Documents which must be filed by it in connection with the Spin-Off Transactions
or which have been filed by it as required by this Agreement, the other Loan
Documents or otherwise with any Governmental Authority.

         (B) Execution and Delivery. The execution, delivery, performance and
filing, as the case may be, of each of the Transaction Documents which must be
executed or filed by the Parent or any of its Subsidiaries in connection with
the Spin-Off Transactions or which have been executed or filed as required by
this Agreement, the other Loan Documents or otherwise and to which the Parent or
any of its Subsidiaries is party, and the consummation of the transactions
contemplated thereby, have been duly approved by the respective boards of
directors and, if necessary, the shareholders of the Parent and its
Subsidiaries, and such approvals have not been rescinded. No other action or
proceedings on the part of the Parent or its Subsidiaries are necessary to
consummate such transactions.

         (C) Transaction Documents. Each of the Transaction Documents to which
the Parent or any of its Subsidiaries is a party has been duly executed,
delivered or filed, as the case may be, by it and constitutes its legal, valid
and binding obligation, enforceable against it in accordance with its terms
(except as enforceability may be limited by bankruptcy, insolvency, or similar
laws affecting the enforcement of creditors' rights generally), is in full force
and effect and no material term or condition thereof has been amended, modified
or waived from the terms and conditions contained in the Transaction Documents
delivered to the Administrative Agent pursuant to Section 5.1 without the prior
written consent of the Administrative Agent (which consent shall not be
unreasonably withheld), and the Parent and its Subsidiaries have, and, to the
best of the Parent's and its Subsidiaries' knowledge, all other parties thereto
have, performed and complied with all the terms, provisions, agreements and
conditions set forth therein and required to be performed or complied with by
such parties, and no unmatured default, default or breach of any covenant by any
such party exists thereunder.

<PAGE>   79

         6.3. No Conflict; Governmental Consents. The execution, delivery and
performance of each of the Loan Documents and other Transaction Documents to
which the Parent or any of its Subsidiaries is a party do not and will not (i)
conflict with the certificate or articles of incorporation or by-laws (or
comparable document) of the Parent or any such Subsidiary, (ii) constitute a
tortious interference with any Contractual Obligation of any Person or conflict
with, result in a breach of or constitute (with or without notice or lapse of
time or both) a default under any Requirement of Law (including, without
limitation, any Environmental Property Transfer Act) or Contractual Obligation
of the Parent or any such Subsidiary, or require termination of any Contractual
Obligation which would result in an aggregate liability in excess of $1,000,000,
(iii) with respect to the Loan Documents, constitute a tortious interference
with any Contractual Obligation of any Person or conflict with, result in a
breach of or constitute (with or without notice or lapse of time or both) a
default under any Requirement of Law (including, without limitation, any
Environmental Property Transfer Act) or Contractual Obligation of the Parent or
any such Subsidiary, or require termination of any Contractual Obligation (other
than the Existing SIC Credit Agreement), (iv) result in or require the creation
or imposition of any Lien whatsoever upon any of the property or assets of the
Parent or any such Subsidiary, other than Liens permitted or created by the Loan
Documents, or (v) require any approval of the Parent's or any such Subsidiary's
board of directors or shareholders except such as have been obtained. Except as

its Subsidiaries is a party do not and will not require any registration with,
consent or approval of, or notice to, or other action to, with or by any
Governmental Authority, including under any Environmental Property Transfer Act,

or which, if not made, obtained or given, individually or in the aggregate could
not reasonably be expected to have a Material Adverse Effect and (ii) filings
necessary to create or perfect security interests in the Collateral.

         6.4. Financial Statements.

         (A) Pro Forma Financials. The combined pro forma balance sheet, income
statements and statements of cash flow of the Parent and its Subsidiaries,
copies of which are contained in the Form 10 and are attached hereto as Schedule
6.4 to this Agreement, present on a pro forma basis the financial condition of
the Parent and such Subsidiaries as of such date, and reflect on a pro forma
basis those liabilities reflected in the notes thereto and resulting from
consummation of the Spin-Off Transactions and the other transactions
contemplated by this Agreement, and the payment or accrual of all transaction
costs payable on or before the Closing Date with respect to any of the
foregoing, and demonstrate that, after giving effect to the Spin-Off
Transactions, the Parent and its Subsidiaries can repay their debts and satisfy
their other obligations as and when due, and can comply with the requirements of
this Agreement. The Projections were prepared in good faith and represent
management's opinion based on the information available to the Parent at the
time so furnished and, since the preparation thereof and up to the Closing Date,
there has occurred no change in the business, financial condition, operations or
prospects of the Parent or any of its Subsidiaries, or the Parent and its
Subsidiaries taken as a whole which has had or could reasonably be expected to
have a Material Adverse Effect.



                                       79
<PAGE>   80

         (B) Audited and Unaudited Financial Statements. Complete and accurate
copies of (i) the audited financial statements and the audit reports related
thereto of SDM, its consolidated Subsidiaries and its dental business affiliates
for the fiscal year ended September 30, 1999 and (ii) unaudited quarterly
financial statements of SDM, its consolidated Subsidiaries and its dental
business affiliates for the fiscal quarter ended June 30, 2000 have been
delivered to the Administrative Agent.

         (C) Usual Conduct of Business. Since the pro forma financial statements
described in Section 6.4(A) and the Projections and since the financial
statements described in Section 6.4(B), the Parent and its Subsidiaries have
conducted their respective operations (including, without limitation, any
operations and transactions with SIC, any holder or holders of any of the Equity
Interests of the Parent, or with any Affiliate of the Parent which is not its
Subsidiary) according to their ordinary and usual course of business and
consistent with past practice, as reflected in such financial statements and
Projections, in all material respects.

         6.5. No Material Adverse Change.

         (A) Prior to Closing Date. Since (i) March 31, 2000 and (ii) the
delivery of the pro forma financial statements described in Section 6.4(A) up to
the Closing Date, in either case, there has occurred no change in the business,
financial condition, operations or prospects of the Parent or any of its
Subsidiaries or the Parent and its Subsidiaries taken as a whole or any other
event which has had or could reasonably be expected to have a Material Adverse
Effect.

         (B) From and After Closing Date. Since the Closing Date, there has
occurred no change in the business, financial condition, operations or prospects
of the Parent or any of its Subsidiaries or the Parent and its Subsidiaries
taken as a whole or any other event which has had or could reasonably be
expected to have a Material Adverse Effect.

         6.6. Taxes.

         (A) Tax Examinations. All deficiencies which have been asserted against
the Parent, or any of its Subsidiaries as a result of any federal, state, local
or foreign tax examination for each taxable year in respect of which an
examination has been conducted have been fully paid or finally settled or are
being contested in good faith, and no issue has been raised by any taxing
authority in any such examination which, by application of similar principles,
reasonably can be expected to result in assertion by such taxing authority of a
material deficiency for any other year not so examined which has not been
reserved for in the Parent's consolidated financial statements to the extent, if
any, required by Agreement Accounting Principles. Except as permitted pursuant
to Section 7.2(D), neither of the Parent, nor any of its Subsidiaries
anticipates any tax liability with respect to the years which have not been
closed pursuant to applicable law.

         (B) Payment of Taxes. All tax returns and reports of the Parent and its
Subsidiaries required to be filed have been timely filed, and all taxes,
assessments, fees and other governmental charges thereupon and upon their
respective property, assets, income and franchises which are shown in such
returns or reports to be due and payable have been paid except those items which
are being contested in good faith and have been reserved for in accordance with
Agreement Accounting Principles except where the failure to have made such
filings or payment would not result in liabilities (including penalties and
fines) in excess of $250,000 in the aggregate. The Parent has no knowledge



                                       80
<PAGE>   81

of any proposed tax assessment against the Parent or any of its Subsidiaries
that will have or could reasonably be expected to have a Material Adverse
Effect.

         6.7. Litigation; Loss Contingencies and Violations. There is no action,
suit, proceeding, arbitration or, to the Parent's knowledge, investigation
before or by any Governmental Authority or private arbitrator pending or, to the
Parent's knowledge, threatened against or affecting the Parent or any of its
Subsidiaries or any property of any of them which, individually or in the
aggregate, could reasonably be expected to result in liabilities in excess of
$5,000,000. In addition, no action, suit, proceeding, arbitration or, to the
Parent's knowledge, investigation before or by any Governmental Authority or
private arbitrator pending or, to the Parent's knowledge, threatened against or
affecting the Parent or any of its Subsidiaries or any property of any of them
(i) challenges the validity or the enforceability of any material provision of
the Transaction Documents or (ii) has or could reasonably be expected to have a
Material Adverse Effect. There is no material loss contingency within the
meaning of Agreement Accounting Principles which has not been reflected in the
consolidated financial statements of the Parent prepared and delivered pursuant
to Section 7.1(A) for the fiscal period during which such material loss
contingency was incurred. Neither the Parent nor any of its Subsidiaries is (A)
in violation of any applicable Requirements of Law which violation will have or
could reasonably be expected to have a Material Adverse Effect, or (B) subject
to or in default with respect to any final judgment, writ, injunction,
restraining order or order of any nature, decree, rule or regulation of any
court or Governmental Authority which will have or could reasonably be expected
to have a Material Adverse Effect.

         6.8. Subsidiaries. Schedule 6.8 to this Agreement (i) contains a
description of the corporate structure of the Parent and its Subsidiaries and
any other Person in which the Parent or any of its Subsidiaries holds an Equity
Interest after giving effect to the Spin-Off Transactions; and (ii) accurately
sets forth (A) the correct legal name and the jurisdiction of incorporation of
the Parent and each direct and indirect Subsidiary of the Parent and the
jurisdictions in which each of the Parent and the direct and indirect Domestic
Incorporated Subsidiaries of the Parent are qualified to transact business as a
foreign corporation, (B) the authorized, issued and outstanding shares of each
class of Capital Stock of the Parent and each of its Subsidiaries and the owners
of such shares (both as of the Closing Date and on a fully-diluted basis), and
(C) a summary of the direct and indirect partnership, joint venture, or other
Equity Interests, if any, of the Parent and each of its Subsidiaries in any
Person that is not a corporation. Except as disclosed on Schedule 6.8, none of
the issued and outstanding Capital Stock of the Parent or any of its
Subsidiaries is subject to any vesting, redemption, or repurchase agreement, and
there are no warrants or options outstanding with respect to such Capital Stock.
The Parent has no direct Subsidiaries other than SDM and Pinnacle Products, Inc.

         6.9. ERISA. Except as disclosed on Schedule 6.9, no Benefit Plan has
incurred any accumulated funding deficiency (as defined in Sections 302(a)(2) of
ERISA and 412(a) of the Code) whether or not waived. Neither the Parent nor any
member of the Controlled Group has incurred any material liability to the PBGC
which remains outstanding other than the payment of premiums, and there are no
premium payments which have become due which are unpaid. Schedule B to the most
recent annual report filed with the IRS with respect to each Benefit Plan and
furnished to the Lenders is complete and accurate. Since the date of each such
Schedule B, there has been no material adverse change in the funding status or
financial condition of the Benefit Plan relating to such Schedule B. Neither the
Parent nor any member of the Controlled Group has (i) failed to make a required




                                       81
<PAGE>   82

contribution or payment to a Multiemployer Plan or (ii) made a complete or
partial withdrawal under Sections 4203 or 4205 of ERISA from a Multiemployer
Plan. Neither the Parent nor any member of the Controlled Group has failed to
make a required installment or any other required payment under Section 412 of
the Code on or before the due date for such installment or other payment.
Neither the Parent nor any member of the Controlled Group is required to provide
security to a Benefit Plan under Section 401(a)(29) of the Code due to a Plan
amendment that results in an increase in current liability for the plan year.
Except as set forth on Schedule 6.9, neither the Parent nor any of its
Subsidiaries maintains or contributes to any employee welfare benefit plan
within the meaning of Section 3(1) of ERISA which provides benefits to employees
after termination of employment other than as required by Section 601 of ERISA.
Each Plan which is intended to be qualified under Section 401(a) of the Code as
currently in effect is so qualified in all material respects, and each trust
related to any such Plan is exempt from federal income tax under Section 501(a)
of the Code as currently in effect. The Parent and each of its Subsidiaries are
in compliance in all material respects with the responsibilities, obligations
and duties imposed on them by ERISA and the Code with respect to all Plans.
Neither the Parent nor any of its Subsidiaries nor any fiduciary of any Plan has
engaged in a nonexempt prohibited transaction described in Sections 406 of ERISA
or 4975 of the Code which could reasonably be expected to subject the Parent or
its Subsidiaries to liability in excess of $5,000,000. Neither the Parent nor
any member of the Controlled Group has taken or failed to take any action which
would constitute or result in a Termination Event, which action or inaction
could reasonably be expected to subject the Parent or any of its Subsidiaries to
liability, individually or in the aggregate, in excess of $5,000,000. Neither
the Parent nor any Subsidiary is subject to any liability under Sections 4063,
4064, 4069, 4204 or 4212(c) of ERISA and no other member of the Controlled Group
is subject to any liability under Sections 4063, 4064, 4069, 4204 or 4212(c) of
ERISA which could reasonably be expected to subject the Parent or any of its
Subsidiaries to liability, individually or in the aggregate, in excess of
$5,000,000 (other than liabilities of any ERISA affiliate which could not, by
operation of law or otherwise, become a liability of the Parent or any
Subsidiary). Except as set forth on Schedule 6.9, neither the Parent nor any of
its Subsidiaries has, by reason of the transactions contemplated hereby, any
obligation to make any payment to any employee pursuant to any Plan or existing
contract or arrangement.

         6.10. Accuracy of Information. The information, exhibits and reports
furnished by or on behalf of the Parent and any of its Subsidiaries to the
Administrative Agent or to any Lender in connection with the negotiation of, or
compliance with, the Loan Documents, the representations and warranties of the
Parent and its Subsidiaries contained in the Loan Documents, and all
certificates and documents delivered to the Administrative Agent and the Lenders
pursuant to the terms thereof, including, without limitation, the Form 10, taken
as a whole, do not contain as of the date furnished any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements contained herein or therein, in light of the circumstances under
which they were made, not misleading.

         6.11. Securities Activities. The Parent and its Subsidiaries are in
compliance with Regulations T, U and X. Margin Stock constitutes less than
twenty-five percent (25%) of the value of those assets of the Parent and its
Subsidiaries which are subject to any limitation on sale, pledge, or other
restriction hereunder.

         6.12. Material Agreements. Neither the Parent nor any of its
Subsidiaries is a party to any Contractual Obligation or subject to any charter
or other corporate restriction which individually or



                                       82
<PAGE>   83

in the aggregate has had or could reasonably be expected to have a Material
Adverse Effect. Neither the Parent nor any of its Subsidiaries has received
notice or has knowledge that (i) it is in default in the performance, observance
or fulfillment of any of the obligations, covenants or conditions contained in
any Contractual Obligation applicable to it, or (ii) any condition exists which,
with the giving of notice or the lapse of time or both, would constitute a
default with respect to any such Contractual Obligation, in each case, except
where such default or defaults, if any, individually or in the aggregate will
not have or could not reasonably be expected to have a Material Adverse Effect.

         6.13. Compliance with Laws. The Parent and its Subsidiaries are in
compliance with all Requirements of Law applicable to them and their respective
businesses, in each case where the failure to so comply individually or in the
aggregate could reasonably be expected to have a Material Adverse Effect.

         6.14. Assets and Properties. The Parent and each of its respective
Subsidiaries has good and marketable title to all of its assets and properties
(tangible and intangible, real or personal) owned by it or a valid leasehold
interest in all of its leased assets (except insofar as marketability may be
limited by any laws or regulations of any Governmental Authority affecting such
assets), and all such assets and property are free and clear of all Liens,
except Liens permitted under Section 7.3(C). Substantially all of the assets and
properties owned by, leased to or used by the Parent and/or each such Subsidiary
of the Parent are in adequate operating condition and repair, ordinary wear and
tear excepted. Neither this Agreement nor any other Transaction Document, nor
any transaction contemplated under any such agreement, will affect any right,
title or interest of the Parent or such Subsidiary in and to any of such assets
in a manner that would have or could reasonably be expected to have a Material
Adverse Effect.

         6.15. Statutory Indebtedness Restrictions. Neither the Parent nor any
of its Subsidiaries is subject to regulation under the Public Utility Holding
Company Act of 1935, the Federal Power Act, the Interstate Commerce Act, or the
Investment Company Act of 1940, or any other foreign, federal or state statute
or regulation which limits its ability to incur indebtedness or its ability to
consummate the transactions contemplated hereby.

         6.16. Insurance. Schedule 6.16 to this Agreement accurately sets forth
all insurance policies and programs currently in effect with respect to the
respective properties, assets, liabilities and business of the Parent and its
Subsidiaries, specifying, for each such policy and program, (i) the amount
thereof, (ii) the risks insured against thereby, (iii) the name of the insurer
and each insured party thereunder, (iv) the policy or other identification
number thereof, (v) the expiration date thereof, and (vi) the annual premium
with respect thereto. Such insurance policies and programs reflect coverage that
is reasonably consistent with prudent industry practice and shall include,
without limitation, property, liability and business interruption insurance. Any
reserves relating to any self-insurance program that is in effect do not at any
time exceed $5,000,000 in the aggregate.

         6.17. Labor Matters. No attempt to organize the employees of the Parent
or any of its Subsidiaries, and no labor disputes, strikes or walkouts affecting
the operations of the Parent or any of its Subsidiaries, is pending, or, to the
Parent's knowledge, threatened, planned or contemplated.

         6.18. Spin-Off Transactions. As of the Closing Date and immediately
prior to the making of the initial Loans, except as set forth on Schedule 6.18
of this Agreement:

              (ii) the Spin-Off Transactions have been approved by all necessary
         corporate action of SIC's and the Parent's Boards of Directors and, if
         required, shareholders, and the terms of the Spin-Off Transactions have
         not been amended, waived or modified in any material respect from those
         set forth in the Form 10 without the approval of the Administrative
         Agent (such approval not to be unreasonably withheld);

              (iii) the Tax Ruling has been obtained for the consummation of the
         Spin-Off Transactions;

              (iv) the Parent and its Subsidiaries (both before and after giving
         effect to the Spin-Off) have received all necessary corporate and
         regulatory approvals for the consummation of the Spin-Off Transactions
         and the financing contemplated hereby; and

              (v) there has been no material adverse change from the information
         set forth in the Form 10 (other than the anticipated restructuring
         charge to be taken prior to consummation of the Spin-Off Transactions
         and disclosed to the Administrative Agent and the Lenders provided the
         Net Worth Condition is satisfied immediately after the consummation of
         the Spin-Off Transactions) and the Projections and other information
         provided to the Lead Arranger and the Lenders and contained in the Bank
         Book.

         6.19. Environmental Matters.

              (iii) neither the Parent, any of its Subsidiaries nor any of their
         respective past or present property or operations are subject to or the
         subject of, any investigation known to the Parent or any of its
         Subsidiaries, any judicial or administrative proceeding, order,
         judgment, decree, settlement or other agreement respecting: (A) any
         material violation of Environmental, Health or Safety Requirements of
         Law; (B) any remedial action; or (C) any material claims or liabilities
         arising from the Release or threatened Release of a Contaminant into
         the environment;

              (iv) there is not now, nor to the Parent's or any of its

         underground storage tanks, aboveground storage tanks, surface
         impoundment or hazardous waste storage facility of any kind, any
         polychlorinated biphenyls (PCBs) used in hydraulic oils, electric

                                       84

         material Contingent Obligation in connection with any Release or
         threatened Release of a Contaminant into the environment.

         (B) Materiality. For purposes of this Section 6.19 "material" means any
noncompliance or basis for liability which could reasonably be likely to subject
the Parent or any of its Subsidiaries to liability, individually or in the
aggregate, in excess of $5,000,000.

         (C) Knowledge. Notwithstanding any term contained in this Section 6.19
to the contrary, the representations and warranties in this Section 6.19 which
relate to (i) real property owned by parties other than any of the Parent or its
Subsidiaries, (ii) previously leased real estate or (iii) any period of time
prior to the date on which the Parent or any of its Subsidiaries acquired

have granted in favor of the Administrative Agent, for the benefit of the
Holders of Secured Obligations, a fully perfected, first priority Lien on, and
security interest in all right, title and interest of the Parent or the

Section 7.3(C) hereof.

         6.23. Special Representations and Warranties of each Subsidiary Swing
Line Borrower. Each Subsidiary Swing Line Borrower represents and warrants to
the Lenders that:

         (A) Organization and Corporate Powers. Such Subsidiary Borrower (i) is
a company duly formed and validly existing and in good standing under the laws
of the state or country of its organization (such jurisdiction being hereinafter
referred to as the "HOME COUNTRY"); (ii) has the requisite power and authority
to own its property and assets and to carry on its business substantially as now
conducted except where the failure to have such requisite authority would not
have a material adverse effect on such Subsidiary Swing Line Borrower; and (iii)
has the requisite power and authority and legal right to execute and deliver the
Alternate Currency Addendum to which it is a party and each other Loan Document
to which it is a party and the performance by it of its obligations thereunder
have been duly authorized by proper corporate proceedings.



                                       85
<PAGE>   86

         (B) Binding Effect. Each Loan Document, including, without limitation,
any Alternate Currency Addendum, executed by such Subsidiary Swing Line Borrower
is the legal, valid and binding obligations of such Subsidiary Swing Line
Borrower enforceable in accordance with their respective terms, except as
enforceability may be limited by bankruptcy, insolvency or similar laws
affecting the enforcement of creditors' rights generally and general equitable
principles.

         (C) No Conflict; Government Consent. Neither the execution and delivery
by such Subsidiary Swing Line Borrower of the Loan Documents to which it is a
party, nor the consummation by it of the transactions therein contemplated to be
consummated by it, nor compliance by such Subsidiary Swing Line Borrower with
the provisions thereof will violate any law, rule, regulation, order, writ,
judgment, injunction, decree or award binding on such Subsidiary Swing Line
Borrower or any of its Subsidiaries or such Subsidiary Swing Line Borrower's or
any of its Subsidiaries' memoranda or articles of association or the provisions
of any indenture, instrument or agreement to which such Subsidiary Swing Line
Borrower or any of its Subsidiaries is a party or is subject, or by which it, or
its property, is bound, or conflict with or constitute a default thereunder, or
result in the creation or imposition of any lien in, of or on the property of
such Subsidiary Swing Line Borrower or any of its Subsidiaries pursuant to the
terms of any such indenture, instrument or agreement in any such case which
violation, conflict, default, creation or imposition could reasonably be
expected to have a material adverse effect on such Subsidiary Swing Line
Borrower. No order, consent, approval, license, authorization, or validation of,
or filing, recording or registration with, or exemption by, any governmental
agency is required to authorize, or is required in connection with the
execution, delivery and performance of, or the legality, validity, binding
effect or enforceability of, any of the Loan Documents.

         (D) Filing. To ensure the enforceability or admissibility in evidence
of this Agreement and each Loan Document to which such Subsidiary Swing Line
Borrower is a party (including, without limitation, any Alternate Currency
Addendum) in its Home Country, it is not necessary that this Agreement or any
other Loan Document to which such Subsidiary Swing Line Borrower is a party or
any other document be filed or recorded with any court or other authority in its
Home Country or that any stamp or similar tax be paid to or in respect of this
Agreement or any other Loan Document of such Subsidiary Swing Line Borrower. The
qualification by any Lender or the Administrative Agent for admission to do
business under the laws of such Subsidiary Swing Line Borrower's Home Country
does not constitute a condition to, and the failure to so qualify does not
affect, the exercise by any Lender or the Administrative Agent of any right,
privilege, or remedy afforded to any Lender or the Administrative Agent in
connection with the Loan Documents to which such Subsidiary Swing Line Borrower
is a party or the enforcement of any such right, privilege, or remedy against
Subsidiary Swing Line Borrower. The performance by any Lender or the
Administrative Agent of any action required or permitted under the Loan
Documents will not (i) violate any law or regulation of such Subsidiary Swing
Line Borrower's Home Country or any political subdivision thereof, (ii) result
in any tax or other monetary liability to such party pursuant to the laws of
such Subsidiary Swing Line Borrower's Home Country or political subdivision or
taxing authority thereof (provided that, should any such action result in any
such tax or other monetary liability to the Lender or the Administrative Agent,
the Borrowers hereby agree to indemnify such Lender or the Administrative Agent,
as the case may be, against (x) any such tax or other monetary liability and (y)
any increase in any tax or other monetary liability which results from such
action by such Lender or the Administrative Agent and, to the extent the
Borrowers make such indemnification, the incurrence of such liability by the
Administrative Agent or any Lender will not constitute a Default) or (iii)
violate any rule or regulation of any federation or organization or similar
entity of which the such Subsidiary Swing Line Borrower's Home Country is a
member.



                                       86
<PAGE>   87

         (E) No Immunity. Neither such Subsidiary Swing Line Borrower nor any of
its assets is entitled to immunity from suit, execution, attachment or other
legal process. Such Subsidiary Swing Line Borrower's execution and delivery of
the Loan Documents to which it is a party constitute, and the exercise of its
rights and performance of and compliance with its obligations under such Loan
Documents will constitute, private and commercial acts done and performed for
private and commercial purposes.

         (F) Application of Representations and Warranties. It is understood and
agreed by the parties hereto that the representations and warranties of each
Subsidiary Swing Line Borrower in this Section 6.23 shall only be applicable to
such Subsidiary Swing Line Borrower on and after the date of its execution of an
Assumption Letter and, if applicable, an Alternate Currency Addendum.

         6.24. Foreign Employee Benefit Matters. (a) Each Foreign Employee
Benefit Plan is in compliance in all material respects with all laws,
regulations and rules applicable thereto and the respective requirements of the
governing documents for such Plan; (b) the aggregate of the accumulated benefit
obligations under all Foreign Pension Plans does not exceed to any material
extent the current fair market value of the assets held in the trusts or similar
funding vehicles for such Plans; (c) with respect to any Foreign Employee
Benefit Plan maintained or contributed to by the Parent or any Subsidiary or any
member of its Controlled Group (other than a Foreign Pension Plan), reasonable
reserves have been established in accordance with prudent business practice or
where required by ordinary accounting practices in the jurisdiction in which
such Plan is maintained; and (d) there are no material actions, suits or claims
(other than routine claims for benefits) pending or, to the knowledge of the
Parent and its Subsidiaries, threatened against the Parent or any Subsidiary of
it or any member of its Controlled Group with respect to any Foreign Employee
Benefit Plan. For purposes of this Section 6.24, the term "material" shall have
the meaning set forth in Section 7.1(D).

                             ARTICLE VII: COVENANTS

         provisions of the respective Collection Account Agreements; provided,
         however, that the requirements set forth in this Section 7.2(O)(i)
         shall be satisfied with respect to any Collection Account that is in
         existence on the Closing Date if such Collection Account is subject to
         a Collection Account Agreement within thirty (30) days following the
         Closing Date. Any of the foregoing collections received by the Parent
         or any of its Subsidiaries or Affiliates and not so deposited, shall be
         deemed to have been received by such Person as the Administrative
         Agent's trustee and, upon such Person's receipt thereof, the Parent
         shall (or shall cause such Subsidiary or Affiliate to) immediately
         transfer all such amounts into a Collection Account in their original
         form. Such deposits shall be remitted to the Administrative Agent, the
         Parent, the applicable Subsidiary or as the Administrative Agent may
         direct, all in accordance with the provisions of the Collection Account
         Agreements.

              (ii) Following the Collection Account Blockage Date and during the
         continuance of a Default giving rise thereto, (a) all payments received
         by the Administrative Agent, all collections of Receivables included in
         the Collateral received by the Administrative Agent, and all proceeds
         of other Collateral received by the Administrative Agent, whether
         through payment or otherwise, will be the sole property of the
         Administrative Agent for the benefit of the Holders of Secured
         Obligations and will be deemed received by the Administrative Agent for
         application to the Obligations pursuant to the terms of this Agreement.

         (P) Insurance. The Parent shall maintain for itself and its
Subsidiaries, or shall cause such Subsidiaries to maintain in full force and
effect, the insurance policies and programs listed on Schedule 6.16 to this
Agreement or substantially similar policies and programs or other policies and
programs as reflect coverage that is reasonably consistent with prudent industry
practice. The Parent shall deliver to the Administrative Agent endorsements in
form and substance acceptable to the Administrative Agent (y) to all "All Risk"
physical damage insurance policies on all of the Parent's and its Subsidiaries'
tangible real and personal property and assets and business interruption
insurance policies naming the Administrative Agent loss payee, and (z) to all
general liability and other liability policies naming the Administrative Agent
an additional insured. In the event the Parent or any Subsidiary at any time or
times hereafter shall fail to obtain or maintain any of the policies or
insurance required herein or to pay any premium in whole or in part relating
thereto, then the Administrative Agent, without waiving or releasing any
obligations or resulting Default hereunder, may at any time or times thereafter
(but shall be under no obligation to do so) obtain and maintain such policies of
insurance and pay such premiums and take any other action with respect thereto
which the Administrative Agent deems advisable. All sums so disbursed by the
Administrative Agent shall constitute part of the Secured Obligations, payable
as provided in this Agreement. In connection with any such disbursements by the
Administrative Agent on behalf of the Parent or its Subsidiaries and in
accordance with the provisions of applicable law, the Administrative Agent
hereby gives the following notice:



                                       97
<PAGE>   98

         Unless you (the Parent and it Subsidiaries) provide us (the
         Administrative Agent) with evidence of the insurance coverage required
         by your agreement with us (i.e., under this Agreement and the Security
         Agreement), we may purchase insurance at your expense to protect our
         interests in your collateral. This insurance may, but need not, protect
         your interests. The coverage that we purchase may not pay any claim
         that you make or any claim that is made against you in connection with
         the collateral. You may later cancel any insurance purchased by us,
         only after providing us with evidence that you have obtained insurance
         as required by our agreement. If we purchase insurance for the
         collateral, you will be responsible for the costs of that insurance,
         including interest and any other charges we may impose in connection
         with the placement of the insurance, until the effective date of the
         cancellation or expiration of the insurance. The costs of the insurance
         may be added to your total outstanding balance or obligation. The costs
         of the insurance may be more than the cost of insurance you may be able
         to obtain on your own.

         (Q) Insurance and Condemnation Proceeds. The Parent directs (and, if
applicable, shall cause each applicable Subsidiary to direct) all insurers under
policies of property damage, boiler and machinery and business interruption
insurance and payors of any condemnation claim or award relating to the property
to pay all proceeds payable under such policies or with respect to such claim or
award for any loss with respect to the Collateral directly to the Administrative
Agent, for the benefit of the Administrative Agent and the Holders of the
Secured Obligations; provided, however, in the event that such proceeds or
awards are less than $1,000,000 ("EXCLUDED PROCEEDS"), unless a Default shall
have occurred and be continuing, the Administrative Agent shall remit such
Excluded Proceeds to SDM (for distribution as appropriate). Each such policy
shall contain a long-form loss-payable endorsement naming the Administrative
Agent as loss payee, which endorsement shall be in form and substance acceptable
to the Administrative Agent. The Administrative Agent shall, upon receipt of
such proceeds (other than Excluded Proceeds) and at SDM's direction, either
apply the same to the principal amount of the Loans outstanding at the time of
such receipt and create a corresponding reserve against the Maximum Revolving
Credit Amount in an amount equal to such application (the "DECISION RESERVE") or
hold them as cash collateral for the Obligations in an interest bearing account.
For up to sixty (60) days from the date of any loss (the "DECISION PERIOD"), SDM
may notify the Administrative Agent that the Parent or the applicable Subsidiary
intends to restore, rebuild or replace the property subject to any insurance
payment or condemnation award and shall, as soon as practicable thereafter,
provide the Administrative Agent detailed information, including a construction
schedule and cost estimates. Should a Default occur at any time during the
Decision Period, should SDM notify the Administrative Agent that the Parent or
the applicable Subsidiary has decided not to rebuild or replace such property
during the Decision Period, or should SDM fail to notify the Administrative
Agent of the Parent's or the applicable Subsidiary's decision during the
Decision Period, then the amounts held as cash collateral pursuant to this
Section 7.2(R) or as the Decision Reserve shall upon the Required Lenders'
direction be applied as a Designated Prepayment pursuant to Section 2.5(B).
Proceeds held as cash collateral pursuant to this Section 7.2(R) or constituting
the Decision Reserve shall be disbursed in accordance with SDM's directions
promptly after receipt of such directions as payments for restoration,
rebuilding or replacement of such property as such amounts become due; provided,
however, should a Default occur after SDM has notified the Administrative Agent
that the Parent or the applicable Subsidiary intends to rebuild or replace the
property, the Decision Reserve or amounts held as cash collateral may, or shall,
upon the Required Lenders' direction, be applied as a Designated Prepayment




                                       98
<PAGE>   99

pursuant to Section 2.5(B). In the event the Decision Reserve is to be applied
as a mandatory prepayment of the Term Loans, SDM shall be deemed to have
requested Revolving Loans in an amount equal to the Decision Reserve, and such
Loans shall be made regardless of any failure of SDM to meet the conditions
precedent set forth in Article V. Upon completion of the restoration, rebuilding
or replacement of such property, the unused proceeds shall constitute Net Cash
Proceeds of an Asset Sale and shall be applied as a Designated Prepayment
pursuant to Section 2.5(B).

         (A) Indebtedness. Neither the Parent nor any of its Subsidiaries shall

         provided, that if the Borrowers or any Guarantor is the obligor on such
         Indebtedness, such Indebtedness shall be expressly subordinate to the
         payment in full in cash of the Secured Obligations on terms
         satisfactory to the Administrative Agent;

              (vi) secured or unsecured purchase money Indebtedness (including

         Section 7.3(C) (such Indebtedness being referred to herein as
         "PERMITTED PURCHASE MONEY INDEBTEDNESS");

              (vii) Indebtedness with respect to surety, appeal and performance
         bonds obtained by the Borrowers or any of their respective Subsidiaries
         in the ordinary course of business;

              (viii) Indebtedness incurred by the Borrowers or any of their
         respective Subsidiaries (whether assumed by the Borrowers or such
         Subsidiary or issued to the seller) in any Permitted Acquisition as
         part of the consideration therefor, provided that (a) such Indebtedness
         is unsecured and is subordinated to the Obligations on terms reasonably

         any time outstanding not exceeding $10,000,000

         (B) Sales of Assets. Neither the Parent nor any of its Subsidiaries

         Equipment that is obsolete, excess or no longer used or useful in the
         Parent's or its Subsidiaries' businesses;

              (ii) transfers of assets between the Loan Parties and any
         wholly-owned Subsidiary thereof or between wholly-owned Subsidiaries of
         such Loan Parties not otherwise prohibited by this Agreement;

be subordinated to the Obligations on terms reasonably accepted to the

              (vi) any Restricted Payments that constitute a payment in respect
         of a purchase price adjustment, earn-out or other similar form of

         but solely to the extent such payment is permitted under Section
         7.3(G)(iv);

              (vii) other Restricted Payments provided that prior to the
         declaration or payment of such Restricted Payment, the Borrowers shall
         deliver to the Administrative Agent a certificate from one of the
         Authorized Officers, demonstrating to the satisfaction of the
         Administrative Agent that after giving effect to such Restricted
         Payment and the incurrence of any Indebtedness permitted by Section
         7.3(A) in connection therewith, on a pro forma basis, as if the
         Restricted Payment and such incurrence of Indebtedness had occurred on
         the first day of the twelve-month period ending on the last day of the
         Borrower's most recently completed fiscal quarter, the Borrower would
         have been in compliance with the financial covenants in Section 7.4 and
         not otherwise in Default.



                                      103
<PAGE>   104

provided, however, that in no event shall any Restricted Payments be declared or
made if either a Default or an Unmatured Default shall have occurred and be
continuing at the date of declaration or payment thereof or would result
therefrom.

of its Subsidiaries shall engage in any business other than the businesses
engaged in by the Parent and its Subsidiaries on the date hereof and any
business or activities which are substantially similar, related or incidental
thereto or logical extensions thereof. The Parent shall not create, capitalize
or acquire any Subsidiary other than the Borrowers and their Subsidiaries. No
Subsidiary of the Parent shall create, acquire or capitalize any Subsidiary (a
"NEW SUBSIDIARY") after the date hereof unless (i) no Default or Unmatured
Default shall have occurred and be continuing or would result therefrom; (ii)
after such creation, acquisition or capitalization, all of the representations
and warranties contained herein shall be true and correct (unless such
representation and warranty is made as of a specific date, in which case, such
representation or warranty shall be true and correct as of such date); and (iii)
after such creation, acquisition or capitalization, the Parent and its

ACQUISITION"):

              (i) no Default or Unmatured Default shall have occurred and be

         any Indebtedness in connection therewith;

              (ii) in the case of an Acquisition of Equity Interests of an
         entity, the Acquisition shall be of at least ninety percent (90%) of
         the Equity Interests of such entity, and such acquired entity shall be

         within ten (10) Business Days following such Acquisition, with the
         Parent or such wholly-owned Subsidiary being the surviving corporation
         following such merger or (y) the results of operations of such entity
         shall be reported on a consolidated basis with the Parent and its
         consolidated Subsidiaries;

              (iii) the purchase is consummated pursuant to a negotiated
         acquisition agreement on a non-hostile basis and approved by the target
         company's board of directors (and shareholders, if necessary) prior to
         the consummation of the Acquisition; and if the acquisition involves
         purchase price consideration in excess of $5,000,000 (including the
         incurrence or assumption of any Indebtedness in connection therewith
         and transaction-related contractual payments, including the maximum
         amounts payable under earn-out or similar contingent purchase price

         which (1) shall have been delivered to the Administrative Agent in
         substantially final form, reasonably in advance of the consummation of
         the proposed Acquisition to provide the Administrative Agent sufficient
         time to review such documents and (2) are reasonably satisfactory to
         the Administrative Agent (including, without limitation, in respect of
         representations, indemnities and opinions) and (b) the results of due
         diligence in respect of such purchase are reasonably satisfactory to
         the Administrative Agent;

<PAGE>   105

              (iv) the purchase price for the Acquisition shall not exceed
         without the prior written consent of the Required Lenders an amount
         equal to (a) $15,000,000 per transaction at any time that the Leverage
         Ratio is greater than or equal to 2.50 to 1.00 or $25,000,000 per
         transaction at any time that the Leverage Ratio is less than 2.50 to
         1.00 or (b) together with all other Permitted Acquisitions permitted
         under this Section 7.3(G), $30,000,000 per year at any time that the
         Leverage Ratio is greater than or equal to 2.50 to 1.00 or $50,000,000

         Indebtedness in connection therewith and transaction-related
         contractual payments, including the maximum amounts payable under
         earn-out or similar contingent purchase price adjustments or
         agreements), and the Parent and its Subsidiaries shall have complied
         with all of the requirements of the Collateral Documents in respect
         thereof;

              (v) the businesses being acquired shall be substantially similar,
         related or incidental to the businesses or activities engaged in by the

         the Administrative Agent and the Lenders a certificate from one of the
         Authorized Officers, demonstrating to the satisfaction of the
         Administrative Agent that after giving effect to such Acquisition and
         the incurrence of any Indebtedness permitted by Section 7.3(A) in
         connection therewith, on a pro forma basis using historical financial
         statements obtained from the seller(s) (broken down by fiscal quarter
         in the Parent's reasonable judgment the amounts from which shall be
         unadjusted unless adjustments thereto have been approved in writing by
         the Administrative Agent) in respect of each such Acquisition as if the
         Acquisition and such incurrence of Indebtedness had occurred on the
         first day of the twelve-month period ending on the last day of the
         Parent's most recently completed fiscal quarter, the Parent would have
         been in compliance with the financial covenants in Section 7.4 and not
         otherwise in Default.

         (H) Transactions with SIC's and the Parent's Shareholders and
Affiliates. Neither the Parent nor any of its Subsidiaries shall directly or
indirectly enter into or permit to exist any transaction (including, without
limitation, the purchase, sale, lease or exchange of any property or the
rendering of any service) with SIC, or make loans or advances to any holder or
holders of any of the Equity Interests of the Parent, or with any Affiliate of
the Parent which is not its Subsidiary, on terms that are less favorable to the
Parent or any of its Subsidiaries, as applicable, than those that could
reasonably be obtained in an arm's length transaction at the time from Persons
who are not such a holder or Affiliate, except for (x) Restricted Payments
permitted by Section 7.3(F) and Investments permitted by Section 7.3(D) and (y)
the transactions set forth on Schedule 7.3(H).

         (I) Restriction on Fundamental Changes. Neither the Parent nor any of
its Subsidiaries shall enter into any merger or consolidation, or liquidate,
wind-up or dissolve (or suffer any liquidation or dissolution), or convey,
lease, sell, transfer or otherwise dispose of, in one transaction or series of
transactions, all or substantially all of the Parent's consolidated business or
property (each such transaction a "FUNDAMENTAL CHANGE"), whether now or
hereafter acquired, except (i) Fundamental Changes permitted under Sections
7.3(B), 7.3(D) or 7.3(G), (ii) a Subsidiary of the Parent may be merged into or
consolidated with the Parent (in which case the Parent shall be the surviving
corporation) or any wholly-owned Subsidiary of the Parent provided the Parent
owns, directly or



                                      105
<PAGE>   106

indirectly, a percentage of the equity of the merged entity not less than the
percentage it owned of the Subsidiary prior to such Fundamental Change and if
the predecessor Subsidiary was a Guarantor, the surviving Subsidiary shall also
be or become a Guarantor hereunder; provided, that if a Borrower is merged into
the Parent (with the Parent being the surviving entity), the Parent shall assume
all of the Obligations of such Borrower hereunder and under the Loan Documents
and shall execute and/or deliver such documentation or take such other actions
as the Administrative Agent shall require to maintain its first, prior security
interest in the Collateral, and (iii) any liquidation of any Subsidiary of the
Parent, into the Parent or another Subsidiary of the Parent, as applicable.

         (J) Sales and Leasebacks. Except as set forth on Schedule 1.1.1,
neither the Parent nor any of its Subsidiaries shall become liable, directly, by
assumption or by Contingent Obligation, with respect to any lease, whether an
operating lease or a Capitalized Lease, of any property (whether real or
personal or mixed), (i) which it or one of its Subsidiaries sold or transferred
or is to sell or transfer to any other Person, or (ii) which it or one of its
Subsidiaries intends to use for substantially the same purposes as any other
property which has been or is to be sold or transferred by it or one of its
Subsidiaries to any other Person in connection with such lease, unless in either
case the sale involved is not prohibited under Section 7.3(B) and the lease
involved is not prohibited under Section 7.3(A) and any related Investment is
not prohibited under Section 7.3(D).

         (K) Margin Regulations. Neither the Parent nor any of its Subsidiaries,
shall use all or any portion of the proceeds of any credit extended under this
Agreement to purchase or carry Margin Stock.

         (L) ERISA. The Parent shall not:

              (i) permit to exist any accumulated funding deficiency (as defined
         in Sections 302 of ERISA and 412 of the Code), with respect to any
         Benefit Plan, whether or not waived;

              (ii) terminate, or permit any Controlled Group member to
         terminate, any Benefit Plan which would result in any liability of the
         Parent or any Controlled Group member under Title IV of ERISA;

              (iii) fail, or permit any Controlled Group member to fail, to pay
         any required installment or any other payment required under Section
         412 of the Code on or before the due date for such installment or other
         payment; or

              (iv) permit any unfunded liabilities with respect to any Foreign
         Pension Plan;

except where such transactions, events, circumstances, or failures are not,
individually or in the aggregate, reasonably expected to result in liability
individually or in the aggregate in excess of $5,000,000.

         (M) Corporate Documents. Neither the Parent nor any of its Subsidiaries
shall amend, modify or otherwise change any of the terms or provisions in any of
their respective constituent documents as in effect on the date hereof in any
manner adverse to the interests of the Lenders, without the prior written
consent of the Required Lenders.

         (N) Fiscal Year. Neither the Parent, the Borrowers nor any of their
consolidated Subsidiaries



                                      106
<PAGE>   107

shall change its fiscal year for accounting or tax purposes from a period
consisting of the twelve-month period ending on the last day of September of
each year (it being understood, however, that for tax purposes, the Parent's
first fiscal year after the consummation of the Spin-Off Transactions will be a
period of less than twelve (12) months).

         (O) Subsidiary Covenants. The Parent will not, and will not permit any
Subsidiary to, create or otherwise cause to become effective or suffer to exist
any consensual encumbrance or restriction of any kind on the ability of any
Subsidiary to pay dividends or make any other distribution on its stock, or make
any other Restricted Payment, pay any Indebtedness or other Obligation owed to
the Parent or any other Subsidiary, make loans or advances or other Investments
in the Parent or any other Subsidiary, or sell, transfer or otherwise convey any
of its property to the Parent or any other Subsidiary, or merge, consolidate
with or liquidate into the Parent or any other Subsidiary.

         (P) Hedging Obligations. The Parent shall not and shall not permit any
of its Subsidiaries to enter into any interest rate, commodity or foreign
currency exchange, swap, collar, cap or similar agreements evidencing Hedging
Obligations, other than interest rate, foreign currency or commodity exchange,
swap, collar, cap or similar agreements entered into by the Subsidiaries
pursuant to which the Subsidiaries have hedged their actual or anticipated
interest rate, foreign currency or commodity exposure. Such permitted hedging
agreements entered into by the Parent's Subsidiaries and any Lender or any
affiliate of any Lender including, without limitation, to hedge floating
interest rate risk in an aggregate notional amount not to exceed at any time an
amount equal to the outstanding balance of the Term Loans at such time are
sometimes referred to herein as "HEDGING AGREEMENTS." In the event a Lender or
any of its Affiliates elects to enter into any Hedging Agreement with any of the
Parent's Subsidiaries, the obligations of such Subsidiary with respect to such
Hedging Agreement shall be Secured Obligations, secured by the collateral
pledged pursuant to the Collateral Documents.

         (Q) Non-Guarantor or Non-Pledged Subsidiaries. The Parent will not
permit (x) the aggregate assets of all Non-Obligor Subsidiaries to exceed 15% of
Consolidated Assets or (y) the aggregate Net Income of all Non-Obligor
Subsidiaries to exceed 15% of Net Income, in each case, as calculated by the
Parent; provided, that it shall not be a violation hereof if, (i) within thirty
(30) days of the date on which an Authorized Officer has knowledge that one or
both of the 15% limitations has been exceeded, the Parent has caused sufficient
Domestic Incorporated Subsidiaries to deliver Collateral Documents and such
other documentation described in Section 7.2(K)(iii) as shall be necessary to
bring the Parent and its Subsidiaries back into compliance with the 15%
limitations set forth above, and (ii) within seventy-five (75) days of the date
on which an Authorized Officer has knowledge that one or both of the 15%
limitations has been exceeded, the Parent has delivered or caused sufficient
parent Domestic Incorporated Subsidiaries to deliver Pledge Agreements with
respect to the Capital Stock of Domestic Incorporated Subsidiaries and/or
Foreign Incorporated Subsidiaries and such other documentation described in
Section 7.2(L)(iii) as shall be necessary to bring the Parent and its
Subsidiaries back into compliance with the 15% limitations set forth above.

         (R) Issuance of Disqualified Stock. From and after the Effective Date,
neither the Parent, nor any of its Subsidiaries shall issue any Disqualified
Stock. All issued and outstanding Disqualified Stock shall be treated as
Indebtedness for borrowed money for all purposes of this Agreement (and as
funded Indebtedness for purposes of Section 7.1(F)), and the amount of such
deemed Indebtedness shall be the aggregate amount of the liquidation preference
of such Disqualified Stock.



                                      107
<PAGE>   108

         (S) Other Indebtedness. The Parent shall not amend, modify or
supplement, or permit any Subsidiary to amend, modify or supplement (or consent
to any amendment, modification or supplement of), any document, agreement or
instrument evidencing Indebtedness that is subordinated to the Obligations (or
any replacements, substitutions or renewals thereof) or pursuant to which such
Indebtedness is issued where such amendment, modification or supplement provides
for the following or which has any of the following effects:

              (i) increases the overall principal amount of any such
         Indebtedness or increases the amount of any single scheduled
         installment of principal or interest;

              (ii) shortens or accelerates the date upon which any installment
         of principal or interest becomes due or adds any additional mandatory
         redemption provisions;

              (iii) shortens the final maturity date of such Indebtedness or
         otherwise accelerates the amortization schedule with respect to such
         Indebtedness;

              (iv) increases the rate of interest accruing on such Indebtedness;

              (v) provides for the payment of additional fees or increases
         existing fees;

              (vi) amends or modifies any financial or negative covenant (or
         covenant which prohibits or restricts the Parent or a Subsidiary from
         taking certain actions) in a manner which is more onerous or more
         restrictive in any material respect to the Parent (or any Subsidiary of
         the Parent) or which is otherwise materially adverse to the Parent
         and/or the Lenders or, in the case of adding covenants, which places
         material additional restrictions on the Parent (or a Subsidiary of the
         Parent) or which requires the Parent or any such Subsidiary to comply
         with more restrictive financial ratios or which requires the Parent to
         better its financial performance from that set forth in the existing
         financial covenants;

              (vii) amends, modifies or adds any affirmative covenant in a
         manner which, when taken as a whole, is materially adverse to the
         Parent and/or the Lenders; or

              (viii) amends, modifies or supplements the subordination
         provisions thereof.

         (T) Tax Ruling. Notwithstanding anything herein to the contrary,
neither the Parent nor any of its Subsidiaries shall engage in any transaction
in contravention of Section 6 of the Tax Sharing and Indemnification Agreement
dated as of November 28, 2000 among SIC and SDS or that would otherwise
adversely affect the Tax Ruling.

         (U) Additional Limitations on the Parent's Activities. In addition to
the foregoing limitations on the Parent's business set forth in this Section
7.3, the Parent shall not engage directly or indirectly (other than indirectly
as a result of its ownership of the Equity Interests of the Borrowers an its
other Subsidiaries) in any operating business enterprise or other activities
other than the direct and indirect ownership of the Equity Interests of the
Borrowers and its other Subsidiaries and the activities incidental thereto.

         7.4. Financial Covenants. The Parent and the Borrowers shall comply
with the following:



                                      108
<PAGE>   109

         (A) Maximum Indebtedness and Maximum Leverage Ratio.

                  (1) Maximum Indebtedness. For the period from the Closing Date
         through and including December 31, 2000, the Parent shall not permit

         consolidated Subsidiaries to exceed $450,000,000.

                  (2) Maximum Leverage Ratio. After December 31, 2000 the Parent
         shall not permit the ratio (the "LEVERAGE RATIO") of (a) Indebtedness
         of the Parent and its consolidated Subsidiaries to (b) EBITDA to be
         greater than:

              (i) 3.50 to 1.00 as of the end of each fiscal quarter for the
         period commencing with the fiscal quarter ending March 31, 2001 through
         the fiscal quarter ending December 31, 2001;

              (ii) 3.25 to 1.00 as of the end of each fiscal quarter for the
         period commencing with the fiscal quarter ending March 31, 2002 through

              (iii) 3.00 to 1.00 as of the end of each fiscal quarter for the

of each such fiscal quarter; and (b) for EBITDA, the actual amount for the
four-quarter period ending on such day.

         (B) Minimum Cash Interest Expense Coverage Ratio. The Parent shall
maintain a ratio (the "CASH INTEREST EXPENSE COVERAGE Ratio") of (1) EBITDA to
(2) Cash Interest Expense for the applicable period of at least:

              (i) 3.00 to 1.00 as of the end of each fiscal quarter for the
         period commencing with the fiscal quarter ending March 31, 2001 through
         the fiscal quarter ending December 31, 2001;

              (ii) 3.50 to 1.00 as of the end of each fiscal quarter for the
         period commencing with the fiscal quarter ending March 31, 2002 through

         Loan Termination Date and (iii) the Tranche B Term Loan Termination
         Date.

In each case the Cash Interest Expense Coverage Ratio shall be determined as of
the last day of each fiscal quarter for the four-quarter period ending on such
day.

         (C) Minimum Consolidated Net Worth. The Parent shall cause Consolidated
Net Worth to be



                                      109

current cash income tax provision by the Parent and its consolidated
Subsidiaries during such period, plus (c) scheduled amortization during such
period of the principal portion of the Tranche A Term Loans and the Tranche B

limitation, Disqualified Stock), beyond any period of grace provided with
respect thereto, which individually or together with other such Indebtedness as
to which any such failure exists has an aggregate outstanding principal amount
in excess of $5,000,000; or any breach, default, amortization event or event of
default shall occur, or any other condition shall exist under any instrument,
agreement or indenture pertaining to any such Indebtedness having such aggregate
outstanding principal amount, beyond any period of grace, if any, provided with
respect thereto, if (i) the effect thereof is to cause an acceleration,
mandatory redemption, a requirement that the Parent or such Subsidiary offer to
purchase such Indebtedness or other required repurchase of such Indebtedness, or
permit the holder(s) of such Indebtedness to accelerate the maturity of any such
Indebtedness or require a redemption or other repurchase of such Indebtedness or
(ii) if such breach, default, amortization event or event of default shall occur
with respect to any Receivables Facility Attributed Indebtedness, the effect
thereof is to cause the early amortization of such Indebtedness or the
replacement of the Person then acting as servicer for such Indebtedness, or to
permit the investors thereunder to request such early amortization or to replace
such Person; or any such Indebtedness shall be otherwise declared to be due and
payable (by acceleration or otherwise) or


                                      111

any Plan applies under Section 412(d) of the Code for a waiver of the minimum

when due (whether by scheduled maturity, required prepayment, acceleration,

outstanding principal amount of which Indebtedness is in excess of $1,000,000 or
any breach, default or event of default shall occur, or any other condition
shall exist, under any instrument, agreement or indenture pertaining to any such
Permitted Parent Indebtedness, if the effect thereof is to cause an
acceleration, mandatory redemption, a requirement that the Parent offer to
purchase such Indebtedness or other required repurchase of such Indebtedness, or
permit the holder(s) of such Indebtedness to accelerate the maturity of any such
Indebtedness or require a redemption or other repurchase of such Indebtedness;

condition contained in any such Hedging Agreement.

A Default shall be deemed "continuing" until cured or until waived in writing in
accordance with Section 9.3.

 ARTICLE IX: ACCELERATION, DEFAULTING LENDERS; WAIVERS, AMENDMENTS AND REMEDIES

         9.1. Termination of Commitments; Acceleration. If any Default described
in Section 8.1(F) or 8.1(G) occurs with respect to the Parent, any Borrower or
any Subsidiary, the obligations of the Lenders to make Loans hereunder and the
obligation of the Issuing Bank to issue Letters of Credit hereunder shall
automatically terminate and the Obligations shall immediately become due and
payable without any election or action on the part of the Administrative Agent
or any Lender. If any other Default occurs, (a) Revolving Lenders with Revolving
Loan Pro Rata Shares greater than fifty percent (50%) may terminate or suspend
the obligations of the Lenders to make Loans hereunder and the obligation of the
Issuing Bank to issue Letters of Credit hereunder, or (b) the Required Lenders
may declare the Obligations to be due and payable, or both, whereupon the
Obligations shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which the Borrowers expressly
waive.

         9.2. Defaulting Lender. In the event that any Lender fails to fund its
Applicable Pro Rata Share of any Advance requested or deemed requested by the
applicable Borrower, which such Lender is obligated to fund under the terms of
this Agreement (the funded portion of such Advance being hereinafter referred to
as a "NON PRO RATA LOAN"), until the earlier of such Lender's cure of such
failure and the termination of the Revolving Loan Commitments, the proceeds of
all amounts thereafter repaid to the Administrative Agent by the applicable
Borrower and otherwise required to be applied to such Lender's share of all
other Obligations pursuant to the terms of this Agreement shall be advanced to
the applicable Borrower by the Administrative Agent on behalf of such Lender to
cure, in full or in part, such failure by such Lender, but shall nevertheless be
deemed to have been paid to such Lender in satisfaction of such other
Obligations. Notwithstanding anything in this Agreement to the contrary:

              (i) the foregoing provisions of this Section 9.2 shall apply only
         with respect to the proceeds of payments of Obligations and shall not
         affect the conversion or continuation of Loans pursuant to Section
         2.10;

              (ii) any such Lender shall be deemed to have cured its failure to
         fund its Applicable Pro Rata Share of any Advance at such time as an
         amount equal to such Lender's original Applicable Pro Rata Share of the
         requested principal portion of such Advance is fully funded to the
         applicable Borrower, whether made by such Lender itself or by operation
         of the terms of this Section 9.2, and whether or not the Non Pro Rata
         Loan with respect thereto has been repaid, converted or continued;



                                      114
<PAGE>   115

              (iii) amounts advanced to the applicable Borrower to cure, in full
         or in part, any such Lender's failure to fund its Applicable Pro Rata
         Share of any Advance ("CURE LOANS") shall bear interest at the rate
         applicable to Floating Rate Loans in effect from time to time, and for
         all other purposes of this Agreement shall be treated as if they were
         Floating Rate Loans;

              (iv) regardless of whether or not a Default has occurred or is
         continuing, and notwithstanding the instructions of the applicable
         Borrower as to its desired application, all repayments of principal
         which, in accordance with the other terms of this Agreement, would be
         applied to the outstanding Floating Rate Loans shall be applied first,
         ratably to all Floating Rate Loans constituting Non Pro Rata Loans,
         second, ratably to Floating Rate Loans other than those constituting
         Non Pro Rata Loans or Cure Loans and, third, ratably to Floating Rate
         Loans constituting Cure Loans;

              (v) for so long as and until the earlier of any such Lender's cure
         of the failure to fund its Applicable Pro Rata Share of any Advance and
         the termination of the Revolving Loan Commitments, the term "Required
         Lenders" for purposes of this Agreement shall mean Lenders (excluding
         all Lenders whose failure to fund their respective Applicable Pro Rata
         Share of such Advance have not been so cured) whose Pro Rata Shares
         represent greater than fifty percent (50%) of the aggregate Pro Rata
         Shares of such Lenders; and

              (vi) for so long as and until any such Lender's failure to fund
         its Applicable Pro Rata Share of any Advance is cured in accordance
         with Section 9.2(ii), (A) such Lender shall not be entitled to any
         commitment fees or non-use fees with respect to its Revolving Loan
         Commitment and (B) such Lender shall not be entitled to any letter of
         credit fees, which commitment fees and letter of credit fees shall
         accrue in favor of the Lenders which have funded their respective
         Applicable Pro Rata Share of such requested Advance, shall be allocated
         among such performing Lenders ratably based upon their relative
         Revolving Loan Commitments, and shall be calculated based upon the
         average amount by which the aggregate Revolving Loan Commitments of
         such performing Lenders exceeds the sum of (I) the outstanding
         principal amount of the Loans owing to such performing Lenders, plus
         (II) the outstanding Reimbursement Obligations owing to such performing
         Lenders, plus (III) the aggregate participation interests of such
         performing Lenders arising pursuant to Section 3.6 with respect to
         undrawn and outstanding Letters of Credit.

         9.3. Amendments. Subject to the provisions of this Article IX, the
Required Lenders (or the Administrative Agent with the consent in writing of the
Required Lenders) and the Borrowers may enter into agreements supplemental
hereto for the purpose of adding or modifying any provisions to the Loan
Documents or changing in any manner the rights of the Lenders or the Borrowers
hereunder or waiving any Default hereunder; provided, however, that no such
supplemental agreement shall, without the consent of each Lender affected
thereby:

              (i) Postpone or extend the Revolving Loan Termination Date, the
         Tranche A Term Loan Termination Date, the Tranche B Term Loan
         Termination Date or any other date fixed for any payment of principal
         of, or interest on, the Loans, the Reimbursement Obligations or any
         fees or other amounts payable to such Lender (except with respect to
         (a) any modifications




                                      115
<PAGE>   116

         of the provisions relating to amounts, timing or application of
         prepayments of Loans and other Obligations, which modification shall
         require only the approval of the Required Lenders; provided, however,
         that (x) if such modifications would affect the order of application of
         any mandatory prepayments to the Tranche A Term Loans, such
         modifications shall also require the approval of Lenders with Tranche A
         Pro Rata Shares equal to or greater than fifty percent (50%) or (y) if
         such modifications would affect the order of application of any
         mandatory prepayments to the Tranche B Term Loans, such modifications
         shall also require the approval of Lenders with Tranche B Pro Rata
         Shares equal to or greater than fifty percent (50%) and (b) a waiver of
         the application of the default rate of interest pursuant to Section
         2.11 hereof which waiver shall require only the approval of the
         Required Lenders).

              (ii) Reduce the principal amount of any Loans or L/C Obligations,
         or reduce the rate or extend the time of payment of interest or fees
         thereon (other than (i) a waiver of the application of the default rate
         of interest pursuant to Section 2.11 hereof, and (ii) as a result of a
         change in the definition of Leverage Ratio or any of the components
         thereof or the method of calculation thereof).

              (iii) Reduce the percentage specified in the definition of
         Required Lenders or any other percentage of Lenders specified to be the
         applicable percentage in this Agreement to act on specified matters or
         amend the definitions of "Applicable Pro Rata Share", "Pro Rata Share",
         "Required Lenders", "Revolving Loan Pro Rata Share", "Tranche A Pro
         Rata Share" or "Tranche B Pro Rata Share".

              (iv) Increase the amount of the Revolving Loan Commitment, the
         Tranche A Term Loan Commitment or the Tranche B Term Loan Commitment of
         any Lender hereunder or increase any Lender's Revolving Loan Pro Rata
         Share, Tranche A Pro Rata Share, Tranche B Pro Rata Share or Pro Rata
         Share.

              (v) Permit a Borrower to assign its rights under this Agreement.

              (vi) Other than pursuant to a transaction permitted by the terms
         of this Agreement, release all or substantially all of the Collateral.

              (vii) Other than pursuant to a transaction permitted by the terms
         of this Agreement, release any Guarantor from its obligations under a
         Guaranty.

              (viii) Amend Section 13.3 or this Section 9.3.

No amendment of any provision of this Agreement relating to (a) the
Administrative Agent shall be effective without the written consent of the
Administrative Agent, (b) Swing Line Loans shall be effective without the
written consent of the Swing Line Bank and (c) the Issuing Bank shall be
effective without the written consent of the Issuing Bank. The Administrative
Agent may waive payment of the fee required under Section 14.3(B) without
obtaining the consent of any of the Lenders.

         The Administrative Agent may notify the other parties to this Agreement
of any amendments to this Agreement which the Administrative Agent reasonably
determines to be necessary as a result of the commencement of the third stage of
the European Economic and



                                      116
<PAGE>   117

Monetary Union. Notwithstanding anything to the contrary contained herein, any
amendments so notified shall take effect in accordance with the terms of the
relevant notification.

         9.4. Preservation of Rights. No delay or omission of the Lenders or the
Administrative Agent to exercise any right under the Loan Documents shall impair
such right or be construed to be a waiver of any Default or an acquiescence
therein, and the making of a Loan or the issuance of a Letter of Credit
notwithstanding the existence of a Default or the inability of the Borrowers to
satisfy the conditions precedent to such Loan or issuance of such Letter of
Credit shall not constitute any waiver or acquiescence. Any single or partial
exercise of any such right shall not preclude other or further exercise thereof
or the exercise of any other right, and no waiver, amendment or other variation
of the terms, conditions or provisions of the Loan Documents whatsoever shall be
valid unless in writing signed by the requisite number of Lenders required
pursuant to Section 9.3, and then only to the extent in such writing
specifically set forth. All remedies contained in the Loan Documents or by law
afforded shall be cumulative and all shall be available to the Administrative
Agent and the Lenders until all of the Termination Conditions shall have been
satisfied.

                              ARTICLE X: GUARANTY

         10.1. Guaranty. For valuable consideration, the receipt of which is
hereby acknowledged, and to induce the Lenders to make advances to each Borrower
and to issue and participate in Letters of Credit and Swing Line Loans, the
Parent hereby absolutely and unconditionally guarantees prompt payment when due,
whether at stated maturity, upon acceleration or otherwise, and at all times
thereafter, of any and all existing and future Obligations of the Borrowers to
the Administrative Agent, the Lenders, the Swing Line Bank, the Issuing Lenders,
or any of them, under or with respect to the Loan Documents, whether for
principal, interest, fees, expenses or otherwise (collectively, the "PARENT
GUARANTEED OBLIGATIONS").

         10.2. Waivers; Subordination of Subrogation.

              (i) The Parent waives notice of the acceptance of this guaranty
         and of the extension or continuation of the Parent Guaranteed
         Obligations or any part thereof. The Parent further waives presentment,
         protest, notice of notices delivered or demand made on any Borrower or
         action or delinquency in respect of the Parent Guaranteed Obligations
         or any part thereof, including any right to require the Administrative
         Agent and the Lenders to sue any Borrower, any other guarantor or any
         other Person obligated with respect to the Parent Guaranteed
         Obligations or any part thereof, or otherwise to enforce payment
         thereof against any collateral securing the Parent Guaranteed
         Obligations or any part thereof; provided, that if at any time any
         payment of any portion of the Parent Guaranteed Obligations is
         rescinded or must otherwise be restored or returned upon the
         insolvency, bankruptcy or reorganization of any of the Borrowers or
         otherwise, the Parent's obligations hereunder with respect to such
         payment shall be reinstated at such time as though such payment had not
         been made and whether or not the Administrative Agent or the Lenders
         are in possession of this guaranty. The Administrative Agent and the
         Lenders shall have no obligation to disclose or discuss with the Parent
         their assessments of the financial condition of the Borrowers.



                                      117
<PAGE>   118

              (ii) Until the Parent Guaranteed Obligations have been
         indefeasibly paid in full in cash, the Parent (i) shall have no right
         of subrogation with respect to such Parent Guaranteed Obligations and
         (ii) waives any right to enforce any remedy which the Holders of
         Secured Obligations or any Administrative Agent now have or may
         hereafter have against any Borrower, any endorser or any guarantor of
         all or any part of the Parent Guaranteed Obligations or any other
         Person, and the Parent waives any benefit of, and any right to
         participate in, any security or collateral given to the Holders of
         Secured Obligations and the Administrative Agent to secure the payment
         or performance of all or any part of the Parent Guaranteed Obligations
         or any other liability of any Borrower to the Holders of Secured
         Obligations. Should the Parent have the right, notwithstanding the
         foregoing, to exercise its subrogation rights, the Parent hereby
         expressly and irrevocably (A) subordinates any and all rights at law or
         in equity to subrogation, reimbursement, exoneration, contribution,
         indemnification or set off that it may have to the indefeasible payment
         in full in cash of the Parent Guaranteed Obligations and (B) waives any
         and all defenses available to a surety, guarantor or accommodation
         co-obligor until the Parent Guaranteed Obligations are indefeasibly
         paid in full in cash. The Parent acknowledges and agrees that this
         subordination is intended to benefit the Administrative Agent and the
         Holders of Secured Obligations and shall not limit or otherwise affect
         the Parent's liability hereunder or the enforceability of this
         Guaranty, and that the Administrative Agent, the Holders of Secured
         Obligations and their respective successors and assigns are intended
         third party beneficiaries of the waivers and agreements set forth in
         this Section 10.2.

         10.3. Guaranty Absolute. This guaranty is a guaranty of payment and not
of collection, is a primary obligation of the Parent and not one of surety, and
the validity and enforceability of this guaranty shall be absolute and
unconditional irrespective of, and shall not be impaired or affected by any of
the following: (a) any extension, modification or renewal of, or indulgence with
respect to, or substitutions for, the Parent Guaranteed Obligations or any part
thereof or any agreement relating thereto at any time; (b) any failure or
omission to enforce any right, power or remedy with respect to the Parent
Guaranteed Obligations or any part thereof or any agreement relating thereto, or
any collateral; (c) any waiver of any right, power or remedy with respect to the
Parent Guaranteed Obligations or any part thereof or any agreement relating
thereto or with respect to any collateral; (d) any release, surrender,
compromise, settlement, waiver, subordination or modification, with or without
consideration, of any collateral, any other guarantees with respect to the
Parent Guaranteed Obligations or any part thereof, or any other obligation of
any Person with respect to the Parent Guaranteed Obligations or any part
thereof; (e) the enforceability or validity of the Parent Guaranteed Obligations
or any part thereof or the genuineness, enforceability or validity of any
agreement relating thereto or with respect to any collateral; (f) the
application of payments received from any source to the payment of obligations
other than the Parent Guaranteed Obligations, any part thereof or amounts which
are not covered by this guaranty even though the Administrative Agent and the
Lenders might lawfully have elected to apply such payments to any part or all of
the Parent Guaranteed Obligations or to amounts which are not covered by this
guaranty; (g) any change in the ownership of any Borrower or the insolvency,
bankruptcy or any other change in the legal status of any Borrower; (h) the
change in or the imposition of any law, decree, regulation or other governmental
act which does or might impair, delay or in any way affect the validity,
enforceability or the payment when due of the Parent Guaranteed Obligations; (i)
the failure of the Parent or any Borrower to maintain in full force, validity or
effect or to obtain or renew when required all governmental and other approvals,
licenses or consents required in connection with the Parent Guaranteed
Obligations or this guaranty, or to take any other action required in connection
with the



                                      118
<PAGE>   119

performance of all obligations pursuant to the Parent Guaranteed Obligations or
this guaranty; (j) the existence of any claim, setoff or other rights which the
Parent may have at any time against any Borrower, or any other Person in
connection herewith or an unrelated transaction; or (k) any other circumstances,
whether or not similar to any of the foregoing, which could constitute a defense
to a guarantor; all whether or not the Parent shall have had notice or knowledge
of any act or omission referred to in the foregoing clauses (a) through (k) of
this paragraph. It is agreed that the Parent's liability hereunder is several
and independent of any other guarantees or other obligations at any time in
effect with respect to the Parent Guaranteed Obligations or any part thereof and
that the Parent's liability hereunder may be enforced regardless of the
existence, validity, enforcement or non-enforcement of any such other guarantees
or other obligations or any provision of any applicable law or regulation
purporting to prohibit payment by any Borrower of the Parent Guaranteed
Obligations in the manner agreed upon between the Borrower and the
Administrative Agent and the Lenders.

         10.4. Acceleration. The Parent agrees that, as between the Parent on
the one hand, and the Lenders and the Administrative Agent, on the other hand,
the obligations of each Borrower guaranteed under this Article X may be declared
to be forthwith due and payable, or may be deemed automatically to have been
accelerated, as provided in Section 9.1 hereof for purposes of this Article X,
notwithstanding any stay, injunction or other prohibition (whether in a
bankruptcy proceeding affecting such Borrower or otherwise) preventing such
declaration as against such Borrower and that, in the event of such declaration
or automatic acceleration, such obligations (whether or not due and payable by
such Borrower) shall forthwith become due and payable by the Parent for purposes
of this Article X.

         10.5. Marshaling; Reinstatement. None of the Lenders nor the
Administrative Agent nor any Person acting for or on behalf of the Lenders or
the Administrative Agent shall have any obligation to marshal any assets in
favor of the Parent or against or in payment of any or all of the Parent
Guaranteed Obligations. If the Parent or any other guarantor of all or any part
of the Parent Guaranteed Obligations makes a payment or payments to any Lender
or the Administrative Agent, which payment or payments or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to the Parent or any other guarantor or any other
Person, or their respective estates, trustees, receivers or any other party,
including, without limitation, the Parent, under any bankruptcy law, state or
federal law, common law or equitable cause, then, to the extent of such payment
or repayment, the part of the Parent Guaranteed Obligations which has been paid,
reduced or satisfied by such amount shall be reinstated and continued in full
force and effect as of the time immediately preceding such initial payment,
reduction or satisfaction.

         10.6. Termination Date. This guaranty shall continue in effect until
the earlier of (a) the Facility Termination Date, and (b) the date on which this
Agreement has otherwise expired or been terminated in accordance with its terms
and all of the Parent Guaranteed Obligations have been paid in full in cash,
subject to the proviso in Section 10.2.

                         ARTICLE XI: GENERAL PROVISIONS

         11.1. Survival of Representations. All representations and warranties
of the Parent and the



                                      119
<PAGE>   120

Borrowers contained in this Agreement shall survive delivery of this Agreement
and the making of the Loans herein contemplated so long as any principal,
accrued interest, fees, or any other amount due and payable under any Loan
Document is outstanding and unpaid (other than contingent reimbursement and
indemnification obligations) and so long as the Commitments have not been
terminated.

         11.2. Governmental Regulation. Anything contained in this Agreement to
the contrary notwithstanding, no Lender shall be obligated to extend credit to
the Borrowers in violation of any limitation or prohibition provided by any
applicable statute or regulation.

         11.3. Performance of Obligations. The Borrowers agree that the
Administrative Agent may, but shall have no obligation to (i) at any time, pay
or discharge taxes, liens, security interests or other encumbrances levied or
placed on or threatened against any Collateral to the extent any such Borrower
is required by the terms hereof to pay any such amount, but has not done so and
(ii), after the occurrence and during the continuance of a Default, to make any
other payment or perform any act required of the Borrowers under any Loan
Document or take any other action which the Administrative Agent in its
discretion deems necessary or desirable to protect or preserve the Collateral ,
including, without limitation, any action to (x) effect any repairs or obtain
any insurance called for by the terms of any of the Loan Documents and to pay
all or any part of the premiums therefor and the costs thereof and (y) pay any
rents payable by any Borrower or other Subsidiary Guarantor which are more than
thirty (30) days past due, or as to which the landlord has given notice of
termination, under any lease. The Administrative Agent shall use its reasonable
efforts to give the applicable Borrower notice of any action taken under this
Section 11.3 prior to the taking of such action or promptly thereafter provided
the failure to give such notice shall not affect the applicable Borrower's
obligations in respect thereof. The Borrowers agree to pay the Administrative
Agent, upon demand, the principal amount of all funds advanced by the
Administrative Agent under this Section 11.3, together with interest thereon at
the rate from time to time applicable to Floating Rate Loans from the date of
such advance until the outstanding principal balance thereof is paid in full. If
any Borrower fails to make payment in respect of any such advance under this
Section 11.3 within one (1) Business Day after the date the applicable Borrower
receives written demand therefor from the Administrative Agent, the
Administrative Agent shall promptly notify each Lender and each Lender agrees
that it shall thereupon make available to the Administrative Agent, in Dollars
in immediately available funds, the amount equal to such Lender's Pro Rata Share
of such advance. If such funds are not made available to the Administrative
Agent by such Lender within one (1) Business Day after the Administrative
Agent's demand therefor, the Administrative Agent will be entitled to recover
any such amount from such Lender together with interest thereon at the Federal
Funds Effective Rate for each day during the period commencing on the date of
such demand and ending on the date such amount is received. The failure of any
Lender to make available to the Administrative Agent its Pro Rata Share of any
such unreimbursed advance under this Section 11.3 shall neither relieve any
other Lender of its obligation hereunder to make available to the Administrative
Agent such other Lender's Pro Rata Share of such advance on the date such
payment is to be made nor increase the obligation of any other Lender to make
such payment to the Administrative Agent. All outstanding principal of, and
interest on, advances made under this Section 11.3 shall constitute Obligations
secured by the Collateral until paid in full by the Borrowers.

         11.4. Headings. Section headings in the Loan Documents are for
convenience of reference only,



                                      120
<PAGE>   121

and shall not govern the interpretation of any of the provisions of the Loan
Documents.

         11.5. Entire Agreement. The Loan Documents and the fee letter agreement
between the Administrative Agent, the Arranger, SIC and the Parent dated October
24, 2000 embody the entire agreement and understanding among the Borrowers, the
Parent, the Administrative Agent and the Lenders and supersede all prior
agreements and understandings among the Borrowers, the Parent, the
Administrative Agent and the Lenders relating to the subject matter thereof.

         11.6. Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other Lender (except to the extent to which
the Administrative Agent is authorized to act as such). The failure of any
Lender to perform any of its obligations hereunder shall not relieve any other
Lender from any of its obligations hereunder. This Agreement shall not be
construed so as to confer any right or benefit upon any Person other than the
parties to this Agreement and their respective successors and assigns.

         11.7. Expenses; Indemnification.

         (A) Expenses. The Parent and the Borrowers shall reimburse the
Administrative Agent and the Arranger for any reasonable costs, any internal
legal charges and any out-of-pocket expenses (including reasonable attorneys'
and paralegals' fees and time charges of attorneys and paralegals for the
Administrative Agent, which attorneys and paralegals may be employees of the
Administrative Agent) paid or incurred by the Administrative Agent or the
Arranger in connection with the preparation, negotiation, execution, delivery,
syndication, review, amendment, modification, and administration of the Loan
Documents. The Parent and the Borrowers also agree to reimburse the
Administrative Agent and the Arranger and the Lenders for any costs, any
internal legal charges and any out-of-pocket expenses (including attorneys' and
paralegals' fees and time charges of attorneys and paralegals for the
Administrative Agent and the Arranger and the Lenders, which attorneys and
paralegals may be employees of the Administrative Agent or the Arranger or the
Lenders) paid or incurred by the Administrative Agent or the Arranger or any
Lender in connection with the collection of the Obligations and enforcement of
the Loan Documents. In addition to expenses set forth above, the Parent and the
Borrowers agree to reimburse the Administrative Agent, promptly after the
Administrative Agent's request therefor, for each audit, or other business
analysis performed by or for the benefit of the Lenders in connection with this
Agreement or the other Loan Documents in an amount equal to the Administrative
Agent's then customary charges for each person employed to perform such audit or
analysis, plus all reasonable costs and expenses (including without limitation,
travel expenses) incurred by the Administrative Agent in the performance of such
audit or analysis. Administrative Agent shall provide the Parent and the
Borrowers with a detailed statement of all reimbursements requested under this
Section 11.7(A).

         (B) Indemnity. The Parent and the Borrowers further agree to defend,
protect, indemnify, and hold harmless the Administrative Agent, the Arranger and
each and all of the Lenders and each of their respective Affiliates, and each of
such Administrative Agent's, Arranger's, Lender's, or Affiliate's respective
officers, directors, trustees, investment advisors, employees, attorneys and
Administrative Agent (including, without limitation, those retained in
connection with the satisfaction or attempted satisfaction of any of the
conditions set forth in Article V) (collectively, the




                                      121
<PAGE>   122

"INDEMNITEES") from and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, claims, costs, expenses of any
kind or nature whatsoever (including, without limitation, the fees and
disbursements of counsel for such Indemnitees in connection with any
investigative, administrative or judicial proceeding, whether or not any of such
Indemnitees shall be designated a party thereto), imposed on, incurred by, or
asserted against such Indemnitees in any manner relating to or arising out of:

              (i) this Agreement or any of the other Loan Documents or any of
         the Transaction Documents, or any act, event or transaction related or
         attendant thereto or to the Spin-Off Transactions, the making of the
         Loans, and the issuance of and participation in Letters of Credit
         hereunder, the management of such Loans or Letters of Credit, the use
         or intended use of the proceeds of the Loans or Letters of Credit
         hereunder, or any of the other transactions contemplated by the
         Transaction Documents; or

              (ii) any liabilities, obligations, responsibilities, losses,
         damages, personal injury, death, punitive damages, economic damages,
         consequential damages, treble damages, intentional, willful or wanton
         injury, damage or threat to the environment, natural resources or
         public health or welfare, costs and expenses (including, without
         limitation, attorney, expert and consulting fees and costs of
         investigation, feasibility or remedial action studies), fines,
         penalties and monetary sanctions, interest, direct or indirect, known
         or unknown, absolute or contingent, past, present or future relating to
         violation of any Environmental, Health or Safety Requirements of Law
         arising from or in connection with the past, present or future
         operations of the Parent, the Borrowers, their Subsidiaries or any of
         their respective predecessors in interest, or, the past, present or
         future environmental, health or safety condition of any respective
         property of the Parent, the Borrowers or their Subsidiaries, the
         presence of asbestos-containing materials at any respective property of
         the Parent, the Borrowers or their Subsidiaries or the Release or
         threatened Release of any Contaminant into the environment
         (collectively, the "INDEMNIFIED MATTERS");

provided, however, neither the Parent nor any Borrower shall have any obligation
to an Indemnitee hereunder with respect to Indemnified Matters caused solely by
or resulting solely from (i) the willful misconduct or Gross Negligence of such
Indemnitee with respect to the Loan Documents or (ii) legal proceedings
commenced against or disputes among the Administrative Agent or any Lender by
any other Lender or its participants or the Administrative Agent so long as no
Default has occurred or is continuing and such proceedings or disputes do not
arise from actions taken at the request of the Parent or any of its
Subsidiaries, in the case of either clause (i) or (ii), as determined by the
final non-appealed judgment of a court of competent jurisdiction. If the
undertaking to indemnify, pay and hold harmless set forth in the preceding
sentence may be unenforceable because it is violative of any law or public
policy, the Parent or the applicable Borrower shall contribute the maximum
portion which it is permitted to pay and satisfy under applicable law, to the
payment and satisfaction of all Indemnified Matters incurred by the Indemnitees.

         (C) Waiver of Certain Claims; Settlement of Claims. Each of the
Administrative Agent, the Arranger, the Parent and the Borrowers further agree
to assert no claim against any of the Indemnitees or each other on any theory of
liability seeking consequential, special, indirect, exemplary or punitive
damages. No settlement shall be entered into by the Parent, the Borrowers or any
of their respective Subsidiaries with respect to any claim, litigation,
arbitration or other



                                      122
<PAGE>   123

proceeding relating to or arising out of the transactions evidenced by this
Agreement, the other Loan Documents or in connection with the Spin-Off
Transactions (whether or not the Administrative Agent or any Lender or any
Indemnitee is a party thereto) unless such settlement releases all Indemnitees
from any and all liability with respect thereto.

         (D) Survival of Agreements. The obligations and agreements of the
Parent and the Borrowers under this Section 11.7 shall survive the termination
of this Agreement.

         11.8. Numbers of Documents. All statements, notices, closing documents,
and requests hereunder shall be furnished to the Administrative Agent with
sufficient counterparts as may be requested by the Administrative Agent so that
the Administrative Agent may furnish one to each of the Lenders, if appropriate.

         11.9. Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

         11.10. Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable, or invalid in any jurisdiction
shall, as to that jurisdiction, be inoperative, unenforceable, or invalid
without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

         11.11. Nonliability of Lenders. The relationship between the Borrowers
and the Lenders and the Administrative Agent shall be solely that of borrower
and lender. Neither the Administrative Agent nor any Lender shall have any
fiduciary responsibilities to the Borrowers. Neither the Administrative Agent
nor any Lender undertakes any responsibility to any Borrower to review or inform
any Borrower of any matter in connection with any phase of the Borrowers'
business or operations.

         11.12. GOVERNING LAW. THE ADMINISTRATIVE AGENT ACCEPTS THIS AGREEMENT,
ON BEHALF OF ITSELF AND THE LENDERS, AT CHICAGO, ILLINOIS BY ACKNOWLEDGING AND
AGREEING TO IT THERE. ANY DISPUTE BETWEEN ANY BORROWER AND THE ADMINISTRATIVE
AGENT, ANY LENDER OR ANY OTHER HOLDER OF SECURED OBLIGATIONS ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER LOAN

RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (INCLUDING Section 735 ILCS
105/5-1 ET SEQ. BUT OTHERWISE WITHOUT REGARD TO THE CONFLICTS OF LAWS
PROVISIONS) OF THE STATE OF ILLINOIS.

         11.13. CONSENT TO JURISDICTION; VENUE; SERVICE OF PROCESS; JURY TRIAL.

         (A) EXCLUSIVE JURISDICTION. EXCEPT AS PROVIDED IN SUBSECTION (B), EACH
OF THE PARTIES HERETO AGREES THAT ALL DISPUTES AMONG THEM ARISING OUT OF,

<PAGE>   124

THE OTHER LOAN DOCUMENTS WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR
OTHERWISE, SHALL BE RESOLVED EXCLUSIVELY BY STATE OR FEDERAL COURTS LOCATED IN

CONSIDERING THE DISPUTE.

         (B) OTHER JURISDICTIONS. EACH BORROWER AGREES THAT THE ADMINISTRATIVE

RIGHT TO PROCEED AGAINST EACH BORROWER OR ITS RESPECTIVE PROPERTY IN A COURT IN
ANY LOCATION TO ENABLE SUCH PERSON TO (1) OBTAIN PERSONAL JURISDICTION OVER ANY
BORROWER OR (2) REALIZE ON THE COLLATERAL GRANTED IN CONNECTION HEREWITH, OR (3)
IN ORDER TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF SUCH
PERSON. EACH BORROWER AGREES THAT IT WILL NOT ASSERT ANY PERMISSIVE
COUNTERCLAIMS IN ANY PROCEEDING BROUGHT BY SUCH PERSON IN A LOCATION OUTSIDE OF
ILLINOIS TO REALIZE ON ANY SECURITY FOR THE OBLIGATIONS OR TO ENFORCE A JUDGMENT
OR OTHER COURT ORDER IN FAVOR OF SUCH PERSON; PROVIDED THAT THE BORROWERS' RIGHT
TO ASSERT PERMISSIVE COUNTERCLAIMS IN STATE OR FEDERAL COURTS LOCATED IN
CHICAGO, ILLINOIS SHALL BE PRESERVED. EACH BORROWER WAIVES ANY OBJECTION THAT IT

PROCEEDING DESCRIBED IN THIS SUBSECTION (B).

         (C) VENUE. THE LENDERS, THE PARENT AND EACH BORROWER IRREVOCABLY WAIVES

THE ABILITY OF THE ADMINISTRATIVE AGENT OR ANY LENDER TO SERVE ANY SUCH WRITS,
PROCESS OR SUMMONSES IN ANY OTHER MANNER PERMITTED BY APPLICABLE LAW.

         (E) WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES

                                      124
<PAGE>   125

OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION

DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY
AND THAT ANY PARTY HERETO MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS
AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES
HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

         11.14. Other Transactions. Each of the Administrative Agent, the
Arranger, the Lenders, the Swing Line Bank, the Issuing Bank and the Borrowers
acknowledge that the Lenders (or Affiliates of the Lenders) may, from time to
time, effect transactions for their own accounts or the accounts of customers,
and hold positions in loans or options on loans of the Borrowers, their
Subsidiaries and other companies that may be the subject of this credit
arrangement and nothing in this Agreement shall impair the right of any such
Person to enter into any such transaction (to the extent it is not expressly
prohibited by the terms of this Agreement) or give any other Person any claim or
right of action hereunder as a result of the existence of the credit
arrangements hereunder, all of which are hereby waived. In addition, certain
Affiliates of one or more of the Lenders are or may be securities firms and as
such may effect, from time to time, transactions for their own accounts or for
the accounts of customers and hold positions in securities or options on
securities of the Borrowers, their Subsidiaries and other companies that may be
the subject of this credit arrangement and nothing in this Agreement shall
impair the right of any such Person to enter into any such transaction (to the
extent it is not expressly prohibited by the terms of this Agreement) or give
any other Person any claim or right of action hereunder as a result of the
existence of the credit arrangements hereunder, all of which are hereby waived.
Each of the Administrative Agent, the Arranger and Arranger, the Lenders, the
Swing Line Bank, the Issuing Bank and the Borrowers acknowledges and consents to
these multiple roles, and further acknowledges that the fact that any such unit
or Affiliate is providing another service or product or proposal therefor to the
Borrowers or any of their respective Subsidiaries does not mean that such
service, product, or proposal is or will be acceptable to any of the
Administrative Agent, the Arranger and Arranger, the Lenders, the Swing Line
Bank or the Issuing Bank.

         11.15. No Strict Construction. The parties hereto have participated
jointly in the negotiation and drafting of this Agreement. In the event an
ambiguity or question of intent or interpretation arises, this Agreement shall
be construed as if drafted jointly by the parties hereto and no presumption or
burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any provisions of this Agreement.

         11.16. Subordination of Intercompany Indebtedness. Each of the
Borrowers and the Parent (herein, the "LENDING ENTITY") agrees that any and all
claims of such Lending Entity against any other Borrower, the Parent or any
Obligated Entity with respect to any "Intercompany Indebtedness" (as hereinafter
defined), (herein, the "OBLIGATED ENTITY") any endorser, obligor or any other
guarantor of all or any part of the Obligations, or against any of its
properties shall be subordinate and subject in right of payment to the prior
payment, in full and in cash, of all Obligations and Hedging Obligations under
Hedging Agreements; provided that, and not in contravention of the foregoing, so
long as no Default has occurred and is continuing the Lending Entity may make
loans to and receive payments in the ordinary course with respect to such
Intercompany Indebtedness from each such Obligated Entity to the extent
permitted by the terms of this Agreement and the other Loan




                                      125
<PAGE>   126

Documents. Notwithstanding any right of the Lending Entity to ask, demand, sue
for, take or receive any payment from any Obligated Entity, all rights, liens
and security interests of the Lending Entity, whether now or hereafter arising
and howsoever existing, in any assets of any Obligated Entity shall be and are
subordinated to the rights of the Holders of Secured Obligations and the
Administrative Agent in those assets. The Lending Entity shall have no right to
possession of any such asset or to foreclose upon any such asset, whether by
judicial action or otherwise, unless and until all of the Obligations (other
than contingent indemnity obligations) and the Hedging Obligations under Hedging
Agreements shall have been fully paid and satisfied (in cash) and all financing
arrangements pursuant to any Loan Document or Hedging Agreement among the
Borrowers and the Holders of Secured Obligations (or any affiliate thereof) have
been terminated. If all or any part of the assets of any Obligated Entity, or
the proceeds thereof, are subject to any distribution, division or application
to the creditors of such Obligated Entity, whether partial or complete,
voluntary or involuntary, and whether by reason of liquidation, bankruptcy,
arrangement, receivership, assignment for the benefit of creditors or any other
action or proceeding, or if the business of any such Obligated Entity is
dissolved or if substantially all of the assets of any such Obligated Entity are
sold, then, and in any such event (such events being herein referred to as an
"INSOLVENCY EVENT"), any payment or distribution of any kind or character,
either in cash, securities or other property, which shall be payable or
deliverable upon or with respect to any indebtedness of any Obligated Entity to
the Lending Entity ("INTERCOMPANY INDEBTEDNESS") shall be paid or delivered
directly to the Administrative Agent for application on any of the Obligations
and Hedging Obligations under the Hedging Agreements, due or to become due,
until such Obligations and Hedging Obligations (other than contingent indemnity
obligations) shall have first been fully paid and satisfied (in cash). Should
any payment, distribution, security or instrument or proceeds thereof be
received by the Lending Entity upon or with respect to the Intercompany
Indebtedness after an Insolvency Event prior to the satisfaction of all of the
Obligations (other than contingent indemnity obligations) and Hedging
Obligations under Hedging Agreements and the termination of all financing
arrangements pursuant to any Loan Document or Hedging Agreement among the
Borrowers and the Holders of Secured Obligations (and their affiliates), the
Lending Entity shall receive and hold the same in trust, as trustee, for the
benefit of the Holders of Secured Obligations and shall forthwith deliver the
same to the Administrative Agent, for the benefit of such Persons, in precisely
the form received (except for the endorsement or assignment of the Lending
Entity where necessary), for application to any of the Obligations and such
Hedging Obligations, due or not due, and, until so delivered, the same shall be
held in trust by the Lending Entity as the property of the Holders of Secured
Obligations. If the Lending Entity fails to make any such endorsement or
assignment to the Administrative Agent, the Administrative Agent or any of its
officers or employees are irrevocably authorized to make the same. Each Lending
Entity agrees that until the Obligations (other than the contingent indemnity
obligations) and such Hedging Obligations have been paid in full (in cash) and
satisfied and all financing arrangements pursuant to any Loan Document or
Hedging Agreement among the Borrowers and the Holders of Secured Obligations
(and their affiliates) have been terminated, the Lending Entity will not assign
or transfer to any Person (other than the Administrative Agent) any claim the
Lending Entity has or may have against any Obligated Entity.

         11.17. Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles. If any changes in generally accepted accounting principles are
hereafter required or permitted and are adopted by the Parent or any of its
Subsidiaries with the



                                      126
<PAGE>   127

agreement of its independent certified public accountants and such changes
result in a change in the method of calculation of any of the financial
covenants, tests, restrictions or standards herein or in the related definitions
or terms used therein ("ACCOUNTING CHANGES"), the parties hereto agree, at the
Parent's request, to enter into negotiations, in good faith, in order to amend
such provisions in a credit neutral manner so as to reflect equitably such
changes with the desired result that the criteria for evaluating the Parent's
and its Subsidiaries' financial condition shall be the same after such changes
as if such changes had not been made; provided, however, until such provisions
are amended in a manner reasonably satisfactory to the Administrative Agent and
the Required Lenders, no Accounting Change shall be given effect in such
calculations and all financial statements and reports required to be delivered
hereunder shall be prepared in accordance with Agreement Accounting Principles
without taking into account such Accounting Changes. In the event such amendment
is entered into, all references in this Agreement to Agreement Accounting
Principles shall mean generally accepted accounting principles as of the date of
such amendment.

                     ARTICLE XII: THE ADMINISTRATIVE AGENT

         12.1. Appointment; Nature of Relationship. ABN AMRO is appointed by the
Lenders as the Administrative Agent hereunder and under each other Loan
Document, and each of the Lenders irrevocably authorizes the Administrative
Agent to act as the contractual representative of such Lender with the rights
and duties expressly set forth herein and in the other Loan Documents. The
Administrative Agent agrees to act as such contractual representative upon the
express conditions contained in this Article XII. Notwithstanding the use of the
defined term "Administrative Agent," it is expressly understood and agreed that
the Administrative Agent shall not have any fiduciary responsibilities to any
Holder of Secured Obligations by reason of this Agreement and that the
Administrative Agent is merely acting as the representative of the Lenders with
only those duties as are expressly set forth in this Agreement and the other
Loan Documents. In its capacity as the Lenders' contractual representative, the
Administrative Agent (i) does not assume any fiduciary duties to any of the
Holders of Secured Obligations, (ii) is a "representative" of the Holders of
Secured Obligations within the meaning of Section 9-105 of the Uniform
Commercial Code and (iii) is acting as an independent contractor, the rights and
duties of which are limited to those expressly set forth in this Agreement and
the other Loan Documents. Each of the Lenders, for itself and on behalf of its
affiliates as Holders of Secured Obligations, agrees to assert no claim against
the Administrative Agent on any agency theory or any other theory of liability
for breach of fiduciary duty, all of which claims each Holder of Secured
Obligations waives.

         12.2. Powers. The Administrative Agent shall have and may exercise such
powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties or fiduciary duties to the Lenders, or any obligation to the
Lenders to take any action hereunder or under any of the other Loan Documents
except any action specifically provided by the Loan Documents required to be
taken by the Administrative Agent.

         12.3. General Immunity. Neither the Administrative Agent nor any of its
directors, officers, Administrative Agent or employees shall be liable to the
Borrowers, the Lenders or any Lender for any action taken or omitted to be taken
by it or them hereunder or under any other Loan Document or in connection
herewith or therewith except to the extent such action or inaction is found in a
final



                                      127
<PAGE>   128

judgment by a court of competent jurisdiction to have arisen solely from the
Gross Negligence or willful misconduct of such Person.

         12.4. No Responsibility for Loans, Creditworthiness, Collateral,
Recitals, Etc. Neither the Administrative Agent nor any of its directors,
officers, Administrative Agent or employees shall be responsible for or have any
duty to ascertain, inquire into, or verify (i) any statement, warranty or
representation made in connection with any Loan Document or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document; (iii) the satisfaction of any
condition specified in Article V, except receipt of items required to be
delivered solely to the Administrative Agent; (iv) the existence or possible
existence of any Default or (v) the validity, effectiveness or genuineness of
any Loan Document or any other instrument or writing furnished in connection
therewith. The Administrative Agent shall not be responsible to any Lender for
any recitals, statements, representations or warranties herein or in any of the
other Loan Documents, for the perfection or priority of the Liens on any of the
Collateral, or for the execution, effectiveness, genuineness, validity,
legality, enforceability, collectibility, or sufficiency of this Agreement or
any of the other Loan Documents or the transactions contemplated thereby, or for
the financial condition of any guarantor of any or all of the Obligations, the
Parent, the Borrowers or any of their respective Subsidiaries.

         12.5. Action on Instructions of Lenders. The Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder and under any other Loan Document in accordance with written
instructions signed by the Required Lenders (or all of the Lenders in the event
that and to the extent that this Agreement expressly requires such), and such
instructions and any action taken or failure to act pursuant thereto shall be
binding on all of the Lenders and on all owners of Loans and on all Holders of
Secured Obligations. The Administrative Agent shall be fully justified in
failing or refusing to take any action hereunder and under any other Loan
Document unless it shall first be indemnified to its satisfaction by the Lenders
pro rata against any and all liability, cost and expense that it may incur by
reason of taking or continuing to take any such action.

         12.6. Employment of Administrative Agent and Counsel. The
Administrative Agent may execute any of its duties as the Administrative Agent
hereunder and under any other Loan Document by or through employees,
Administrative Agent, and attorney-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
Administrative Agent, for the default or misconduct of any such Administrative
Agent or attorneys-in-fact selected by it with reasonable care. The
Administrative Agent shall be entitled to advice of counsel concerning the
contractual arrangement between the Administrative Agent and the Lenders and all
matters pertaining to the Administrative Agent's duties hereunder and under any
other Loan Document.

         12.7. Reliance on Documents; Counsel. The Administrative Agent shall be
entitled to rely upon any notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and, in respect
to legal matters, upon the opinion of counsel selected by the Administrative
Agent, which counsel may be employees of the Administrative Agent.

         12.8. The Administrative Agent's Reimbursement and Indemnification. The
Lenders agree to reimburse and indemnify the Administrative Agent ratably in
proportion to their respective Pro Rata Shares (i) for any amounts not
reimbursed by any Borrower for which the Administrative Agent is




                                      128
<PAGE>   129

entitled to reimbursement by any Borrower under the Loan Documents, (ii) for any
other expenses incurred by the Administrative Agent on behalf of the Lenders, in
connection with the preparation, execution, delivery, administration and
enforcement of the Loan Documents and (iii) for any liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements of any kind and nature whatsoever which may be imposed on,
incurred by or asserted against the Administrative Agent in any way relating to
or arising out of the Loan Documents or any other document delivered in
connection therewith or the transactions contemplated thereby, or the
enforcement of any of the terms thereof or of any such other documents, provided
that no Lender shall be liable for any of the foregoing to the extent any of the
foregoing is found in a final non-appealable judgment by a court of competent
jurisdiction to have arisen solely from the Gross Negligence or willful
misconduct of the Administrative Agent.

         12.9. Rights as a Lender. With respect to its Revolving Loan
Commitment, its Tranche A Term Loan Commitment, Tranche B Term Loan Commitment,
Loans made by it, and Letters of Credit issued by it, the Administrative Agent
shall have the same rights and powers hereunder and under any other Loan
Document as any Lender or Issuing Bank and may exercise the same as though it
were not the Administrative Agent, and the term "Lender" or "Lenders" or
"Issuing Bank" shall, unless the context otherwise indicates, include the
Administrative Agent in its individual capacity. The Administrative Agent may
accept deposits from, lend money to, and generally engage in any kind of trust,
debt, equity or other transaction, in addition to those contemplated by this
Agreement or any other Loan Document, with the Parent or any of its Subsidiaries
in which such Person is not prohibited hereby from engaging with any other
Person.

         12.10. Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Administrative Agent, the Arranger
or any other Lender and based on the financial statements prepared by the Parent
and the Borrowers and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this
Agreement and the other Loan Documents. Each Lender also acknowledges that it
will, independently and without reliance upon the Administrative Agent, the
Arranger or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement and the other Loan Documents.

         12.11. Successor Administrative Agent. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders and the
Borrowers. Upon any such resignation, the Required Lenders shall have the right
to appoint, on behalf of the Borrowers and the Lenders, a successor
Administrative Agent. If no successor Administrative Agent shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within thirty days after the retiring Administrative Agent's giving notice of
resignation, then the retiring Administrative Agent may appoint, on behalf of
the Borrowers and the Lenders, a successor Administrative Agent. Notwithstanding
anything herein to the contrary, so long as no Default has occurred and is
continuing, each such successor Administrative Agent shall be subject to
approval by the Borrowers, which approval shall not be unreasonably withheld or
delayed. Such successor Administrative Agent shall be a commercial bank having
capital and retained earnings of at least $500,000,000. Upon the acceptance of
any appointment as the Administrative Agent hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring Administrative Agent, and the retiring Administrative Agent
shall be discharged from its duties and obligations hereunder and




                                      129
<PAGE>   130

under the other Loan Documents. After any retiring Administrative Agent's
resignation hereunder as Administrative Agent, the provisions of this Article
XII shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as the Administrative Agent
hereunder and under the other Loan Documents.

         12.12. Collateral Documents.

         (A) Authority to Take Action. Each Lender authorizes the Administrative
Agent to enter into each of the Collateral Documents to which it is a party and
to take all action contemplated by such documents. Each Lender agrees that no
Holder of Secured Obligations (other than the Administrative Agent) shall have
the right individually to seek to realize upon the security granted by any
Collateral Document, it being understood and agreed that such rights and
remedies may be exercised solely by the Administrative Agent for the benefit of
the Holders of Secured Obligations upon the terms of the Collateral Documents.

         (B) Authority to Execute and Deliver. In the event that any Collateral
is hereafter pledged by any Person as collateral security for the Obligations,
the Administrative Agent is hereby authorized to execute and deliver on behalf
of the Holders of Secured Obligations any Loan Documents necessary or
appropriate to grant and perfect a Lien on such Collateral in favor of the
Administrative Agent on behalf of the Holders of Secured Obligations.

         (C) Authority to Release Liens. The Lenders hereby authorize the
Administrative Agent, at its option and in its discretion, to release any Lien
granted to or held by the Administrative Agent upon any Collateral (i) upon
termination of the Commitments and payment and satisfaction of all of the
Obligations at any time arising under or in respect of this Agreement or the
Loan Documents or the transactions contemplated hereby or thereby; (ii) as
permitted by, but only in accordance with, the terms of the applicable Loan
Document; or (iii) if approved, authorized or ratified in writing by the
Required Lenders, unless such release is required to be approved by all of the
Lenders hereunder. Upon request by the Administrative Agent at any time, the
Lenders will confirm in writing the Administrative Agent's authority to release
particular types or items of Collateral pursuant to this Section 12.12(C).

         (D) Additional Authority. Upon any sale or transfer of assets
constituting Collateral which is expressly permitted pursuant to the terms of
any Loan Document, or consented to in writing by the Required Lenders or all of
the Lenders, as applicable, and as soon as practicable, but in any event no
later than five (5) Business Days' following the written request by the
Borrowers, the Administrative Agent shall (and is hereby irrevocably authorized
by the Lenders to) execute such documents as may be necessary to evidence the
release of the Liens granted to the Administrative Agent for the benefit of the
Holders of Secured Obligations herein or pursuant hereto upon the Collateral
that was sold or transferred; provided, however, that (i) the Administrative
Agent shall not be required to execute any such document on terms which, in the
Administrative Agent's opinion, would expose the Administrative Agent to
liability or create any obligation or entail any consequence other than the
release of such Liens without recourse or warranty, and (ii) such release shall
not in any manner discharge, affect or impair the Secured Obligations or any
Liens upon (or obligations of the Borrowers or any Subsidiary in respect of) all
interests retained by the Borrowers or any Subsidiary, including (without
limitation) the proceeds of the sale, all of which shall continue to constitute
part of the Collateral.

         12.13. No Duties Imposed on Syndication Agent, Documentation Agent or
Arranger. None of the Persons identified on the cover page to this Agreement,
the signature pages to this Agreement or otherwise in this Agreement as a
"Syndication Agent" or "Documentation Agent" or "Arranger" shall have any right,
power, obligation, liability, responsibility or duty under this Agreement other
than if such Person is a Lender, those applicable to all Lenders as such.
Without limiting the foregoing, none of the Persons identified on the cover page
to this Agreement, the signature pages to this Agreement or otherwise in this
Agreement as a "Syndication Agent" or "Documentation Agent" or "Arranger" shall
have or be deemed to have any fiduciary duty to or fiduciary relationship with
any Lender. In addition to the agreement set forth in Section 12.10, each of the
Lenders acknowledges that it has not relied, and will not rely, on any of the
Persons so identified in deciding to enter into this Agreement or in taking or
not taking action hereunder.

                     ARTICLE XIII: SETOFF; RATABLE PAYMENTS

         13.1. Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if any Default occurs and is continuing, any
Indebtedness from any Lender to any of the Borrowers (including all account
balances, whether provisional or final and whether or not collected or
available) may be offset and applied toward the payment of the Obligations owing
to such Lender, whether or not the Obligations, or any part hereof, shall then
be due and whether or not the Obligations are fully secured.

         13.2. Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
Sections 4.1, 4.2 or 4.4) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligation or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to the obligations owing to them. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall
be made.

         13.3. Application of Payments. Subject to the provisions of Section
9.2, the Administrative Agent shall, unless otherwise specified at the direction
of the Required Lenders which direction shall be consistent with the last two
sentences of this Section 13.3, apply all payments and prepayments in respect of
any Obligations and all proceeds of the Collateral in the following order:

              (i) first, the ratable payment of interest on and then principal
         of any portion of the Loans which the Administrative Agent may have
         advanced on behalf of any Lender for which the Administrative Agent has
         not then been reimbursed by such Lender or the applicable Borrower;

              (ii) second, to the ratable payment of interest on and then
         principal of any advance made under Section 11.3 for which the
         Administrative Agent has not then been paid by the applicable Borrower
         or reimbursed by the Lenders;



                                      131
<PAGE>   132

              (iii) third, to the ratable payment of the Obligations in respect
         of any fees, expenses, reimbursements or indemnities then due to the
         Administrative Agent;

              (iv) fourth, to pay Obligations in respect of any fees, expenses,
         reimbursements or indemnities then due to the Lenders, the Swing Line
         Bank and the Issuing Bank;

              (v) fifth, to pay interest due in respect of Swing Line Loans;

              (vi) sixth, to pay interest due in respect of Loans (other than
         Swing Line Loans) and L/C Obligations;

              (vii) seventh, to the ratable payment or prepayment of principal
         outstanding on Swing Line Loans;

              (viii) eighth, subject to Section 2.5(B), to the ratable payment
         or prepayment of principal outstanding on Loans (other than Swing Line
         Loans) and Reimbursement Obligations in such order as the
         Administrative Agent may determine in its sole discretion;

              (ix) ninth, to the ratable payment or prepayment of Hedging
         Obligations under Hedging Agreements in such order as the
         Administrative Agent may determine in its sole discretion;

              (x) tenth, to provide required cash collateral, if required
         pursuant to Section 3.11; and

              (xi) eleventh, to the ratable payment of all other Obligations.

Unless otherwise designated (which designation shall only be applicable prior to
the occurrence and during the continuance of a Default) by the Borrowers, all
principal payments in respect of Loans (other than Swing Line Loans) shall be
applied first, to repay outstanding Floating Rate Loans, and then to repay
outstanding Eurocurrency Rate Loans with those Eurocurrency Rate Loans which
have earlier expiring Interest Periods being repaid prior to those which have
later expiring Interest Periods. The order of priority set forth in this Section
13.3 and the related provisions of this Agreement are set forth solely to
determine the rights and priorities of the Administrative Agent, the Lenders,
the Swing Line Bank and the Issuing Bank as among themselves. The order of
priority set forth in clauses (iv) through (x) of this Section 13.3 may at any
time and from time to time be changed by all of the Lenders without necessity of
notice to or consent of or approval by the Borrowers, or any other Person;
provided, that the order of priority of payments in respect of Swing Line Loans
may be changed only with the prior written consent of the Swing Line Bank. The
order of priority set forth in clauses (i) through (iii) of this Section 13.3
may be changed only with the prior written consent of the Administrative Agent,
and, in the case of clause (iii), with the prior written consent of the
Arranger.

         13.4. Relations Among Lenders.

         (A) No Action Without Consent. Except with respect to the exercise of
set-off rights of any Lender in accordance with Section 12.1, the proceeds of
which are applied in accordance with this Agreement, each Lender agrees that it
will not take any action, nor institute any actions or proceedings, against the
Borrowers in connection with this Agreement or the other Loan Documents or any
other obligor hereunder or with respect to any Collateral or Loan Document,
without the prior



                                      132
<PAGE>   133

written consent of the Required Lenders or, as may be provided in this Agreement
or the other Loan Documents, at the direction of the Administrative Agent.

         (B) Not Partners; No Liability. The Lenders are not partners or
co-venturers, and no Lender shall be liable for the acts or omissions of, or
(except as otherwise set forth herein in case of the Administrative Agent)
authorized to act for, any other Lender. The Administrative Agent shall have the
exclusive right on behalf of the Lenders to enforce on the payment of the
principal of and interest on any Loan after the date such principal or interest
has become due and payable pursuant to the terms of this Agreement.

         ARTICLE XIV: BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         14.1. Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrowers and
the Lenders and their respective successors and assigns, except that (A) no
Borrower shall have any right to assign its rights or obligations under the Loan
Documents without the consent of all of the Lenders, and any such assignment in
violation of this Section 14.1(A) shall be null and void, and (B) any assignment
by any Lender must be made in compliance with Section 14.3 hereof.
Notwithstanding clause (B) of this Section 14.1 or Section 14.3, (i) any Lender
may at any time, without the consent of the Parent, any Borrower or the
Administrative Agent, assign all or any portion of its rights under this
Agreement to a Federal Reserve Bank and (ii) any Lender which is a fund or
commingled investment vehicle that invests in commercial loans in the ordinary
course of its business may at any time, without the consent of the Parent, any
Borrower or the Administrative Agent, pledge or assign all or any part of its
rights under this Agreement to a trustee or other representative of holders of
obligations owed or securities issued by such Lender as collateral to secure
such obligations or securities; provided, however, that no such assignment or
pledge shall release the transferor Lender from its obligations hereunder. The
Administrative Agent may treat each Lender as the owner of the Loans made by
such Lender hereunder for all purposes hereof unless and until such Lender
complies with Section 14.3 hereof in the case of an assignment thereof or, in
the case of any other transfer, a written notice of the transfer is filed with
the Administrative Agent. Any assignee or transferee of a Loan, Commitment, L/C
Interest or any other interest of a Lender under the Loan Documents agrees by
acceptance thereof to be bound by all the terms and provisions of the Loan
Documents. Any request, authority or consent of any Person, who at the time of
making such request or giving such authority or consent is the owner of any
Loan, shall be conclusive and binding on any subsequent owner, transferee or
assignee of such Loan.

         14.2. Participations.

         (A) Permitted Participants; Effect. Subject to the terms set forth in
this Section 14.2, any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time sell to one or more banks or other
entities ("Participants") participating interests in any Loan owing to such
Lender, any Revolving Loan Commitment of such Lender, any L/C Interest of such
Lender or any other interest of such Lender under the Loan Documents on a pro
rata or non-pro rata basis. In the event of any such sale by a Lender of
participating interests to a Participant, such Lender's obligations under the
Loan Documents shall remain unchanged, such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations,
such Lender shall




                                      133
<PAGE>   134

remain the owner of all Loans made by it for all purposes under the Loan
Documents, all amounts payable by the applicable Borrower under this Agreement
shall be determined as if such Lender had not sold such participating interests,
and the applicable Borrower and the Administrative Agent shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under the Loan Documents except that, for purposes of Article IV
hereof, the Participants shall be entitled to the same rights as if they were
Lenders.

         (B) Voting Rights. Each Lender shall retain the sole right to approve,
without the consent of any Participant, any amendment, modification or waiver of
any provision of the Loan Documents other than any amendment, modification or
waiver with respect to any Loan, Letter of Credit or Revolving Loan Commitment
in which such Participant has an interest which forgives principal, interest or
fees or reduces the interest rate or fees payable pursuant to the terms of this
Agreement with respect to any such Loan or Revolving Loan Commitment, extends
the Termination Date, the Tranche A Term Loan Termination Date or the Tranche B
Term Loan Termination Date, or postpones any date fixed for any
regularly-scheduled payment (but not any prepayment) of principal of, or
interest or fees on, any such Loan or Revolving Loan Commitment, or releases all
or substantially all of the Collateral, if any, securing any such Loan or Letter
of Credit.

         (C) Benefit of Setoff. The Borrowers agree that each Participant shall
be deemed to have the right of setoff provided in Section 13.1 hereof in respect
to its participating interest in amounts owing under the Loan Documents to the
same extent as if the amount of its participating interest were owing directly
to it as a Lender under the Loan Documents, provided that each Lender shall
retain the right of setoff provided in Section 13.1 hereof with respect to the
amount of participating interests sold to each Participant except to the extent
such Participant exercises its right of setoff. The Lenders agree to share with
each Participant, and each Participant, by exercising the right of setoff
provided in Section 13.1 hereof, agrees to share with each Lender, any amount
received pursuant to the exercise of its right of setoff, such amounts to be
shared in accordance with Section 13.2 as if each Participant were a Lender.

         14.3. Assignments.

         (A) Permitted Assignments.

              (i) Any Lender (each such assigning Lender under this Section 14.3
         being a "SELLER") may, in accordance with applicable law, at any time
         assign to one or more banks or other entities (other than the Borrowers
         or any of their Affiliates) ("PURCHASERS") that are, at the time of
         such assignment, entitled to receive interest on the Obligations being
         assigned to such institution without such payment being subject to any
         withholding taxes and, in the case of assignments of the Revolving Loan
         Commitments, are able to make Eurocurrency Rate Loans in the Agreed
         Currencies, all or a portion of its rights and obligations under this
         Agreement (including, without limitation, its Revolving Loan
         Commitment, all Loans owing to it, all of its participation interests
         in existing Letters of Credit and Swing Line Loans, and its obligation
         to participate in additional Letters of Credit and Swing Line Loans
         hereunder) in accordance with the provisions of this Section 14.3. Each
         assignment shall be of a ratable or non-pro rata percentage of all of
         the Seller's rights and obligations under this Agreement (it being
         understood that Lenders with Tranche A Pro Rata Shares greater than
         zero may assign a portion of their interest in the Tranche A Term Loans
         without assigning any other




                                      134
<PAGE>   135

         interest and Lenders with Tranche B Pro Rata Shares greater than zero
         may assign a portion of their interest in the Tranche B Term Loans
         without assigning any other interest). Such assignment shall be
         substantially in the form of Exhibit D hereto and shall not be
         permitted hereunder unless such assignment is either for all of such
         Seller's rights and obligations under the Loan Documents or, without
         the prior written consent of the Administrative Agent, involves loans
         and commitments in an aggregate amount of at least $1,000,000 and
         integral multiples of $1,000,000 in excess thereof (which minimum
         amount (i) shall not apply to any assignment between Lenders, or to an
         Approved Fund or Affiliate of any Lender, and (ii) in any event may be
         waived by the Administrative Agent). The written consent of the
         Administrative Agent, and, prior to the occurrence of a Default, and
         only with respect to any assignment other than to another Lender or an
         Affiliate or Approved Fund of any Lender, the Parent (which consent, in
         each such case, shall not be unreasonably withheld or delayed), shall
         be required prior to an assignment becoming effective with respect to a
         Purchaser which is not a Lender, an Affiliate of such assigning Lender
         or Approved Fund of such assigning Lender; provided, no consent of the
         Parent shall be required in connection with any assignment by any
         Tranche B Term Loan Lender consummated after consultation with the
         Parent during the Syndication Period.

              (ii) Notwithstanding anything to the contrary contained herein,
         any Lender (each such Lender, a "GRANTING BANK") may grant to a conduit
         or special purpose funding vehicle (each such special purpose funding
         vehicle, a "CONDUIT"), identified as such in writing from time to time
         by the applicable Granting Bank to the Administrative Agent and the
         Parent, the option to provide to the Borrowers all or any part of any
         Advance that such Granting Bank would otherwise be obligated to make to
         the applicable Borrower pursuant to this Agreement; provided, that (i)
         nothing herein shall constitute a commitment by any Conduit to make any
         Advance, (ii) if a Conduit elects not to exercise such option or
         otherwise fails to provide all or any part of such Advance, the
         applicable Granting Bank shall be obligated to make such Advance
         pursuant to the terms hereof. The making of an Advance by any Conduit
         hereunder shall utilize the Revolving Loan Commitment of the applicable
         Granting Bank to the same extent, and as if, such Advance were made by
         such Granting Bank. Each party hereto hereby agrees that no Conduit
         shall be liable for any indemnity or other similar payment obligation
         under this Agreement (all liability for which shall remain with the
         applicable Granting Bank). All notices hereunder to any Granting Bank
         or the related Conduit, and all payments in respect of the Obligations
         due to such Granting Bank or the related Conduit, shall be made to such
         Granting Bank. In addition, each Granting Bank shall vote as a Lender
         hereunder without giving effect to any assignment under this Section
         14.3(A)(ii), and no Conduit shall have any vote as a Lender under this
         Agreement for any purpose. In furtherance of the foregoing, each party
         hereto hereby agrees (which agreement shall survive the termination of
         this Agreement) that, prior to the date that is one year and one day
         after the payment in full of all outstanding commercial paper or other
         senior indebtedness of any Conduit, it will not institute against, or
         join any other person in instituting against, such Conduit any
         bankruptcy, reorganization, arrangement, insolvency or liquidation
         proceedings under the laws of the United States or any State thereof.
         In addition, notwithstanding anything to the contrary contained in this
         Section 14.3, any Conduit may (i) with notice to, but without the prior
         written consent of, the Parent and the Administrative Agent and without
         paying any processing or administrative fee therefor, assign all or a
         portion of its interests in any Advances to the Granting Bank or to any
         financial institutions




                                      135

         (consented to by the Parent and the Administrative Agent in accordance
         with the terms of Section 14.3(A)(i)) providing liquidity and/or credit
         support to or for the account of such Conduit to support the funding or
         maintenance of Advances and (ii) disclose on a confidential basis any
         non-public information relating to its Advances to any rating agency,
         commercial paper dealer or provider of any surety, guarantee or credit
         or liquidity enhancement to such Conduit. This Section 14.3(A)(ii) may
         not be amended without the written consent of each Conduit affected
         thereby.

         (B) Effect; Effective Date. Upon (i) delivery to the Administrative
Agent of a notice of assignment, substantially in the form attached as Appendix
I to Exhibit D hereto (a "NOTICE OF ASSIGNMENT"), together with any consent
required by Section 14.3(A) hereof, (ii) payment of a $2,500 fee to the
Administrative Agent for processing such assignment, and (iii) the completion of
the recording requirements in Section 14.3(C), such assignment shall become
effective on the later of such date when the requirements in clauses (i), (ii),
and (iii) are met or the effective date specified in such Notice of Assignment.
The Notice of Assignment shall contain a representation by the Purchaser to the
effect that none of the consideration used to make the purchase of the
Commitment, Loans and L/C Obligations under the applicable assignment agreement
are "plan assets" as defined under ERISA and that the rights and interests of
the Purchaser in and under the Loan Documents will not be "plan assets" under
ERISA. On and after the effective date of such assignment, such Purchaser, if
not already a Lender, shall for all purposes be a Lender party to this Agreement
and any other Loan Documents executed by the Lenders and shall have all the
rights and obligations of a Lender under the Loan Documents, to the same extent
as if it were an original party hereto, and no further consent or action by any
Borrower, the Lenders or the Administrative Agent shall be required to release
the Seller with respect to the percentage of the Aggregate Revolving Loan
Commitment, Loans and Letter of Credit, and Swing Line Loan participations
assigned to such Purchaser; provided, however, that notwithstanding the
foregoing, the Seller shall retain the benefit of the indemnification
obligations of the Parent and its Subsidiaries under this Agreement and the
other Loan Documents for the period prior to the effective date of such
assignment. Upon the consummation of any assignment to a Purchaser pursuant to
this Section 14.3(B), the Seller, the Administrative Agent and the Borrowers
shall make appropriate arrangements so that, to the extent notes have been
issued to evidence any of the transferred Loans, replacement notes are issued to
such Seller and new notes or, as appropriate, replacement notes, are issued to
such Purchaser, in each case in principal amounts reflecting their Revolving
Loan Commitment, Tranche A Term Loans or Tranche B Term Loans, as applicable, as
adjusted pursuant to such assignment.

         (C) The Register. Notwithstanding anything to the contrary in this
Agreement, each Borrower hereby designates the Administrative Agent, and the
Administrative Agent, hereby accepts such designation, to serve as such
Borrower's contractual representative solely for purposes of this Section
14.3(C). In this connection, the Administrative Agent shall maintain at its
address referred to in Section 15.1 a copy of each assignment delivered to and
accepted by it pursuant to this Section 14.3 and a register (the "REGISTER") for
the recordation of the names and addresses of the Lenders and the Revolving Loan
Commitment of, principal amount of and interest on the Loans owing to, each
Lender from time to time and whether such Lender is an original Lender or the
assignee of another Lender pursuant to an assignment under this Section 14.3.
The entries in the Register shall be conclusive and binding for all purposes,
absent manifest error, and the Parent and each of their respective Subsidiaries,
the Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register as a Lender hereunder for all purposes of this
Agreement. The




                                      136
<PAGE>   137

Register shall be available for inspection by any Borrower or any Lender at any
reasonable time and from time to time upon reasonable prior notice.

         14.4. Confidentiality. Subject to Section 14.5, the Administrative
Agent and the Lenders and their respective representatives, consultants and
advisors shall hold all nonpublic information obtained pursuant to the
requirements of this Agreement and identified as such by the Parent or the
Borrowers in accordance with such Person's customary procedures for handling
confidential information of this nature and in accordance with safe and sound
commercial lending or investment practices and in any event may make disclosure
reasonably required by a prospective Transferee in connection with the
contemplated participation or assignment or as required or requested by any
Governmental Authority or any securities exchange or similar self-regulatory
organization or representative thereof or pursuant to a regulatory examination
or legal process, or to any direct or indirect contractual counterparty in swap
agreements or such contractual counterparty's professional advisor, and shall
require any such Transferee to agree (and require any of its Transferees to
agree) to comply with this Section 14.4. In no event shall the Administrative
Agent or any Lender be obligated or required to return any materials furnished
by the Parent or the Borrowers; provided, however, each prospective Transferee
shall be required to agree that if it does not become a participant or assignee
it shall return all materials furnished to it by or on behalf of the Parent or
the Borrowers in connection with this Agreement.

         14.5. Dissemination of Information. The Parent and each Borrower
authorizes each Lender to disclose to any Participant or Purchaser or any other
Person acquiring an interest in the Loan Documents by operation of law (each a
"TRANSFEREE") and any prospective Transferee any and all information in such
Lender's possession concerning the Parent, the Borrowers, their Subsidiaries and
the Collateral; provided that prior to any such disclosure, such prospective
Transferee shall agree to preserve in accordance with Section 14.4 the
confidentiality of any confidential information described therein.

                              ARTICLE XV: NOTICES

         15.1. Giving Notice. Except as otherwise permitted by Section 2.14 with
respect to Borrowing/Election Notices, all notices and other communications
provided to any party hereto under this Agreement or any other Loan Documents
shall be in writing or by telex or by facsimile and addressed or delivered to
such party at its address set forth below its signature hereto or at such other

Day after deposit with a reputable overnight carrier service, with all charges

delivery of any notice to the Parent or any of the Borrowers shall be deemed to
have been delivered to the Parent and each of the Borrowers.

         15.2. Change of Address. The Borrowers, the Parent, the Administrative
Agent and any Lender may each change the address for service of notice upon it
by a notice in writing to the other parties hereto.

all of which taken together shall constitute one agreement, and any of the
parties hereto may execute this Agreement by signing any such counterpart. This
