                                CREDIT AGREEMENT

                  THIS AGREEMENT, dated as of November 17, 1997, by and among
KENNAMETAL INC., a Pennsylvania corporation (the "Borrower"), the Lenders
parties hereto from time to time, and MELLON BANK, N.A., a national banking
association, as agent for the Lender Parties hereunder (in such capacity,
together with its successors in such capacity, the "Administrative Agent").

                  In consideration of the mutual covenants herein contained and
intending to be legally bound, the parties hereto hereby agree as follows:


                                    ARTICLE I
                            DEFINITIONS; CONSTRUCTION

                  1.01. DEFINITIONS; CONSTRUCTION. In addition to other terms
defined elsewhere in this Agreement, as used in this Agreement the terms defined
in Annex A hereto have the meanings given them in such Annex A, and this
Agreement shall be construed in accordance with the provisions of such Annex A.


                                   ARTICLE II
                                 THE FACILITIES

                  2.01.  THE COMMITTED FACILITIES.

                  (a) THE REVOLVING CREDIT FACILITY.

                  (i) REVOLVING CREDIT COMMITMENTS. Subject to the terms and
conditions and relying upon the representations and warranties herein set forth,
each Lender, severally and not jointly, agrees (such agreement being herein
called such Lender's "Revolving Credit Commitment") to make loans (the
"Revolving Credit Loans") to the Borrower at any time or from time to time on or
after the date hereof and to but not including the Revolving Credit Maturity
Date. A Lender shall have no obligation to make any Revolving Credit Loan to the
extent that such Lender's Revolving Credit Usage at any time would exceed such
Lender's Revolving Credit Committed Amount at such time. Each Lender's
"Revolving Credit Committed Amount" at any time shall be equal to the amount set
forth as its "Initial Revolving Credit Committed Amount" opposite its name in
the Commitment Schedule, as such amount may have been reduced under Section
2.01(a)(v) at such time, and subject to transfer to another Lender as provided
in Section 10.14. The sum of the Revolving Credit Committed Amounts of the
Lenders shall not at any time exceed the amount set forth in the Commitment
Schedule opposite the caption "Total Initial Revolving Credit Committed
Amounts."

                  (ii) NATURE OF CREDIT. Within the limits of time and amount
set forth in this Section 2.01(a), and subject to the provisions of this
Agreement, the Borrower may borrow, repay and reborrow Revolving Credit Loans
hereunder.

                  (iii) MATURITY. To the extent not due and payable earlier, the
Revolving Credit Loans shall be due and payable on the Revolving Credit Maturity
Date.

                  (iv) REVOLVING CREDIT COMMITMENT FEE. The Borrower shall pay
to the Administrative Agent for the account of each Lender a commitment fee (the
"Revolving Credit Commitment Fee") for each day from and including the date
hereof to but not including the Revolving Credit Maturity Date, 

<PAGE>   14


which for each day shall be equal to (i) the Revolving Credit Commitment Fee
Percentage for such day, times (ii) 1/360, times (iii) the amount (not less than
zero) equal to (A) such Lender's Revolving Credit Committed Amount on such day,
minus (B) the sum of the outstanding principal amount of such Lender's Revolving
Credit Loans on such day plus such Lender's Pro Rata share of the aggregate
Letter of Credit Exposure on such day. The "Revolving Credit Commitment Fee
Percentage" for any day shall mean the applicable percentage set forth in the
Pricing Grid based on the Status Level on such day. Such Revolving Credit
Commitment Fee shall be due and payable for the preceding period for which such
fee has not been paid on each of the following dates: (x) each Regular Payment
Date, (y) the date of each reduction of the Revolving Credit Committed Amounts
(whether optional or mandatory) on the amount so reduced, and (z) the Revolving
Credit Maturity Date.

                  (v) OPTIONAL AND MANDATORY REDUCTION OF THE REVOLVING CREDIT
COMMITTED AMOUNTS.

                  (A) MANDATORY REDUCTION. On the Merger Date, the aggregate
Revolving Credit Committed Amounts shall automatically be reduced by an amount
(the "Term Loan Aggregate Amount") equal to the lesser of (x) $500,000,000 or
(y) the aggregate Revolving Credit Committed Amounts on such date. The Borrower
shall reduce the aggregate Revolving Credit Committed Amounts from time to time
as required by Section 2.07(b).

                  (B) OPTIONAL REDUCTION. The Borrower may from time to time
reduce the aggregate Revolving Credit Committed Amounts to an aggregate amount
(which may be zero) not less than the sum of the Revolving Credit Usages of the
Lenders plus the amount of all Revolving Credit Usages of the Lenders not yet
outstanding which the Borrower has requested under Sections 2.02, 3.01, 3.02 or
3.03.

                  (C) MECHANICS OF REDUCTION. Each reduction of the Revolving
Credit Committed Amounts shall be applied Pro Rata to the Revolving Credit
Committed Amounts of the Lenders. Each optional reduction of the Revolving
Credit Committed Amounts, and each mandatory reduction of the Revolving Credit
Committed Amounts of the Lenders pursuant to Section 2.07(b), shall be in an
aggregate amount which is an integral multiple of $1,000,000 not less than
$10,000,000. Each optional reduction of the Revolving Credit Committed Amounts,
and each mandatory reduction of the Revolving Credit Committed Amounts pursuant
to Section 2.07, shall be made by providing not less than three Business Days'
notice (which notice shall be irrevocable) to such effect to the Administrative
Agent, and any such reduction in the Revolving Credit Committed Amounts shall be
effective on the date set forth in such notice.

                  (b)  THE TERM LOAN FACILITY.

                  (i) TERM LOAN COMMITMENTS. Subject to the terms and conditions
and relying upon the representations and warranties herein set forth, each
Lender, severally and not jointly, agrees (such agreement being herein called
such Lender's "Term Loan Commitment") to make a loan (collectively, the "Term
Loans") to the Borrower on the Merger Date; provided, that a Lender shall have
no obligation to make a Term Loan if the Revolving Credit Maturity Date shall
have occurred on or before the Merger Date. A Lender shall have no obligation to
make a Term Loan to the extent that the aggregate principal amount of Term Loans
made by such Lender at any time would exceed such Lender's Term Loan Committed
Amount on the Merger Date. Each Lender's "Term Loan Committed Amount" at any
time shall be equal to such Lender's Pro Rata share of the Term Loan Aggregate
Amount on the Merger Date.

                  (ii) NATURE OF CREDIT. The Borrower may not reborrow amounts
repaid with respect to the Term Loans.

<PAGE>   15



                  (iii) SCHEDULED AMORTIZATION. To the extent not due and
payable earlier, the Term Loans shall be due and payable on the dates and in the
aggregate principal amounts set forth in the following table:

<TABLE>
<CAPTION>

                                                                   AGGREGATE PRINCIPAL AMOUNT OF THE
         QUARTERLY AMORTIZATION DATE                               TERM LOANS DUE AND PAYABLE ON SUCH DATE
         ---------------------------------------------------------- ------------------------------------------------
         <S>                                                         <C>         
         Each of First through Fourth (inclusive)                                      Zero
         ---------------------------------------------------------- ------------------------------------------------
         ---------------------------------------------------------- ------------------------------------------------
         Each of Fifth through Eighth (inclusive)                              $ 25,000,000
         ---------------------------------------------------------- ------------------------------------------------
         ---------------------------------------------------------- ------------------------------------------------
         Each of Ninth through Sixteenth (inclusive)                           $ 31,250,000
         ---------------------------------------------------------- ------------------------------------------------
         ---------------------------------------------------------- ------------------------------------------------
         Each of Seventeenth through Twentieth (inclusive)                     $ 37,500,000
         ---------------------------------------------------------- ------------------------------------------------
</TABLE>
In the event that the Term Loan Aggregate Amount is less than $500,000,000
(which is the sum of the scheduled amortization payments set forth in the above
table), the difference shall be applied to reduce each scheduled installment of
the Term Loans set forth in the above table ratably in proportion to the amounts
of such scheduled installments. The unpaid principal amount of the Term Loans
shall in any event be due and payable on the Revolving Credit Maturity Date.

                  (iv) OPTIONAL TERMINATION OF THE TERM LOAN COMMITMENTS. The
Borrower may on or before the Merger Date terminate the Term Loan Commitments in
whole (but not in part); provided, that the Borrower shall have reduced the
Revolving Credit Committed Amounts to zero. The Borrower may not effect a
partial reduction of the Term Loan Committed Amounts. Termination of the Term
Loan Commitments by the Borrower shall be made by providing not less than three
Business Days' notice (which notice shall be irrevocable) to such effect to the
Administrative Agent, and such termination of the Term Loan Commitments shall be
effective on the date set forth in such notice.

                  (c) COMMITTED NOTES. The obligation of the Borrower to repay
the unpaid principal amount of the Committed Loans made to it by each Lender and
to pay interest thereon shall be evidenced in part by promissory notes of the
Borrower, one to each Lender, dated the date hereof (the "Committed Notes"), in
substantially the form attached hereto as Exhibit A-1, payable to the order of
such Lender.

                  2.02.  MAKING OF COMMITTED LOANS.

                  (a) GENERAL. Whenever the Borrower desires that the Lenders
make Committed Loans, the Borrower shall provide Standard Notice to the
Administrative Agent setting forth the following information (a separate notice
being required for Revolving Credit Loans and Term Loans, specifying the type of
Loans to which such notice applies):

                  (i) The date, which shall be a Business Day, on which such
proposed Loans are to be made;

                  (ii) The aggregate principal amount of such proposed Loans,
         which shall be the sum of the principal amounts selected pursuant to
         clause (iii) of this Section 2.02(a), and which (x) in the case of
         Revolving Credit Loans, shall be an integral multiple of $500,000 not
         less than $5,000,000 and (y) in the case of Term Loans, shall be the
         Term Loan Aggregate Amount minus any amount to be converted from
         outstanding Revolving Credit Loans pursuant to Section 2.02(b);


                                      -3-
<PAGE>   16



                  (iii) The interest rate Option or Options selected in
         accordance with Section 2.03(a) and the principal amounts selected in
         accordance with Section 2.03(d) of the Base Rate Portion and each
         Funding Segment of the Euro-Rate Portion of such proposed Loans; and

                  (iv) With respect to each such Funding Segment of such
         proposed Loans, the Funding Period to apply to such Funding Segment,
         selected in accordance with Section 2.03(c).

Standard Notice having been so provided, the Administrative Agent shall promptly
notify each Lender of the information contained therein and of the amount of
such Lender's Loan. Unless any applicable condition specified in Article V has
not been satisfied, on the date specified in such Standard Notice each Lender
shall make the proceeds of its Loan available to the Administrative Agent at the
Administrative Agent's Office, no later than 1:00 p.m., Pittsburgh time, in
funds immediately available at such Office. The Administrative Agent will make
the funds so received available to the Borrower in funds immediately available
at the Administrative Agent's Office.

                  (b) CONVERSION OF REVOLVING CREDIT LOANS TO TERM LOANS. In
lieu of the Lenders funding Term Loans on the date on which Term Loans are to be
made, the Borrower shall convert all or part of the Revolving Credit Loans
outstanding on such date into Term Loans in accordance with this Section
2.02(b). The Borrower shall specify by notice to the Administrative Agent not
later than 9:30 a.m., Pittsburgh time, on the day before the Term Loans are to
be made the following information: (x) the date (which shall be a Business Day)
on which such conversion is to be effective, (y) the aggregate principal amount
of Revolving Credit Loans to be so converted (which shall be the Term Loan
Aggregate Amount or, if less, the outstanding principal amount of the Revolving
Credit Loans on the date of such conversion) and (z) the principal amounts
(selected in accordance with Section 2.03(d)) of the Base Rate Portion and of
each Funding Segment of the Euro-Rate Portion of the outstanding Revolving
Credit Loans to be so converted. Unless a Lender has notified the Administrative
Agent not later than 9:30 a.m., Pittsburgh time, on the date of such proposed
conversion that an applicable condition specified in Article V has not been
satisfied and that such Lender does not desire such conversion to be effected,
on the date specified in such notice the specified principal amount of
outstanding Revolving Credit Loans shall be deemed to have been converted to
Term Loans. The aggregate amount so converted shall be applied Pro Rata to the
outstanding Revolving Credit Loans of each Lender. Funding Periods and
Euro-Rates applicable to portions of Revolving Credit Loans so converted shall
continue to apply to such portions after such conversion (subject to subsequent
adjustment of the Euro-Rates in accordance with the provisions of this
Agreement), and such conversion shall not itself give rise to any right to
payment under Section 2.10(b).

                  2.03.  INTEREST RATES ON COMMITTED LOANS.

                  (a) OPTIONAL BASES OF BORROWING. The unpaid principal amount
of the Committed Loans shall bear interest for each day until due on one or more
bases selected by the Borrower from among the interest rate Options of such
types set forth below. Subject to the provisions of this Agreement, the Borrower
may select different Options to apply simultaneously to different Portions of
the Committed Loans and may select different Funding Segments to apply
simultaneously to different parts of the Euro-Rate Portion of the Committed
Loans. Each interest rate Option (and Funding Period, if applicable) shall apply
separately and without overlap to the Revolving Credit Loans or to the Term
Loans.

                  (i) BASE RATE OPTION: A rate per annum (computed on the basis
         of a year of 365 or 366 days, as the case may be, and actual days
         elapsed) for each day equal to the Base Rate for such day plus the
         Applicable Margin for such day.


                                      -4-
<PAGE>   17

                  (ii) EURO-RATE OPTION: A rate per annum (based on a year of
         360 days and actual days elapsed) for each day equal to the Euro-Rate
         for such day plus the Applicable Margin for such day.

                  (b) APPLICABLE MARGINS. The "Applicable Margin" for each
interest rate Option for each day shall mean the applicable percentage set forth
in the Pricing Grid based on the Status Level on such day.

                  (c) FUNDING PERIODS. At any time when the Borrower shall
select, convert to or renew the Euro-Rate Option to apply to any part of the
Committed Loans, the Borrower shall specify one or more Funding Periods during
which such Option shall apply, such Funding Periods being as set forth in the
table below:

        INTEREST RATE OPTION                   AVAILABLE FUNDING PERIODS

        Euro-Rate Option                       One, two, three or six months
                                               ("Euro-Rate Funding Period");

provided, that:

                  (i) Each Euro-Rate Funding Period shall begin on a London
         Business Day, and the term "month," when used in connection with a
         Euro-Rate Funding Period, shall be construed in accordance with
         prevailing practices in the interbank eurodollar market at the
         commencement of such Euro-Rate Funding Period, as determined by the
         Administrative Agent (which determination shall be conclusive absent
         manifest error);

                  (ii) The Borrower may not select a Euro-Rate Funding Period
         that would end after the Revolving Credit Maturity Date;

                  (iii) The aggregate number of Funding Segments of the
         Euro-Rate Portions of the Committed Loans at any time shall not exceed
         15, and

                  (iv) Unless the Administrative Agent and each Syndication
         Agent otherwise agree in writing, before the date which is 90 days
         after the Closing Date the Borrower may not select a Euro-Rate Funding
         Period longer than one month.

                  (d) TRANSACTIONAL AMOUNTS. Each selection of, conversion from,
conversion to or renewal of an interest rate Option in respect of the Committed
Loans and each payment or prepayment of any Committed Loans shall be in a
principal amount such that after giving effect thereto the aggregate principal
amount of the Base Rate Portion of the Revolving Credit Loans and of the Term
Loans, and the aggregate principal amount of each Funding Segment of the
Euro-Rate Portion of the Revolving Credit Loans and of the Term Loans, shall be
as set forth in the table below:

</TABLE>

                  (e)  EURO-RATE UNASCERTAINABLE; IMPRACTICABILITY.  If

                  (i) on any date on which a Euro-Rate would otherwise be set
         the Administrative Agent shall have determined in good faith (which
         determination shall be conclusive absent manifest error) that:

                           (A) adequate and reasonable means do not exist for
                  ascertaining such Euro-Rate,

                           (B) a contingency has occurred which materially and
                  adversely affects the interbank eurodollar market and, as a
                  result, the Euro-Rate, or

                           (C) Lenders having 50% or more of the aggregate
                  Commitment Percentages have advised the Administrative Agent
                  that the effective cost to such Lender of funding a proposed
                  Funding Segment of the Euro-Rate Portion from a Corresponding
                  Source of Funds shall exceed the Euro-Rate applicable to such
                  Funding Segment, or

                  (ii) at any time any Lender shall have determined (which
         determination shall be conclusive absent manifest error) that the
         making, maintenance or funding of any part of the Euro-Rate Portion has
         been made impracticable or unlawful by compliance by such Lender or its
         Euro-Rate Lending Office in good faith with any Law or guideline or
         interpretation or administration thereof by any Governmental Authority
         charged with the interpretation or administration thereof or with any
         request or directive of any such Governmental Authority (whether or not
         having the force of law);

then, and in any such event, the Administrative Agent or such Lender, as the
case may be, may notify the Borrower of such determination (and any Lender
giving such notice shall notify the Administrative Agent). Upon such date as
shall be specified in such notice (which shall not be earlier than the date such
notice is given), the obligation of each of the Lenders to allow the Borrower to
select, convert to or renew the Euro-Rate Option shall be suspended until the
Administrative Agent or such Lender, as the case may be, shall have later
notified the Borrower (and any Lender giving such notice shall notify the
Administrative Agent) of the Administrative Agent's or such Lender's
determination (which determination shall be conclusive absent manifest error)
that the circumstance giving rise to such previous determination no longer
exists. If any Lender notifies the Borrower of a determination under clause (ii)
of this Section 2.03(e), the Euro-Rate Portions of the Committed Loans of such
Lender (the "Affected Lender") shall automatically be converted to the Base Rate
Option as of the date specified in such notice (and accrued interest thereon
shall be due and payable on such date). If at the time the Administrative Agent
or a Lender makes a determination under clause (i) or (ii) of this Section
2.03(e) the Borrower previously has notified the Administrative Agent that it
wishes to select, convert to or renew the Euro-Rate Option with respect to any
proposed Committed Loans but such Loans have not yet been made, such
notification shall be deemed to provide for selection of, conversion to or
renewal of the Base Rate Option instead of the Euro-Rate Option with respect to
such Committed Loans or, in the case of a determination by a Lender, such
Committed Loans of such Lender.

                  2.04.  CONVERSION OR RENEWAL OF INTEREST RATE OPTIONS.

                  (a) CONVERSION OR RENEWAL. Subject to Section 2.10(b), the
Borrower may convert any part of the Committed Loans from any interest rate
Option or Options to one or more different interest rate Options and may renew
the Euro-Rate Option as to any Funding Segment of the Euro-Rate Portion:

                  (i) At any time with respect to conversion from the Base Rate 
         Option; or

                  (ii) At the expiration of any Funding Period with respect to
         conversions from or renewals of the Euro-Rate Option, as to the Funding
         Segment corresponding to such expiring Funding Period.

Whenever the Borrower desires to convert or renew any interest rate Option or
Options, the Borrower shall provide to the Administrative Agent Standard Notice
setting forth the following information (a separate notice being required for
Revolving Credit Loans and Term Loans, specifying the type of Loans to which
such notice applies):

                  (w) The date, which shall be a Business Day, on which the
         proposed conversion or renewal is to be made;

                  (x) The principal amounts selected in accordance with Section
         2.03(d) of the Base Rate Portion and each Funding Segment of the
         Euro-Rate Portion to be converted from or renewed;

                  (y) The interest rate Option or Options selected in accordance
         with Section 2.03(a) and the principal amounts selected in accordance
         with Section 2.03(d) of the Base Rate Portion and each Funding Segment
         of the Euro-Rate Portion to be converted to; and

                  (z) With respect to each Funding Segment to be converted to or
         renewed, the Funding Period selected in accordance with Section 2.03(c)
         to apply to such Funding Segment.

Standard Notice having been so provided, after the date specified in such
Standard Notice, interest shall be calculated upon the principal amount of such
Loans as so converted or renewed. Interest on the principal amount of any part
of such Loans converted or renewed (automatically or otherwise) shall be due and
payable on the conversion or renewal date.

                  (b) FAILURE TO CONVERT OR RENEW. Absent due notice from the
Borrower of conversion or renewal in the circumstances described in Section
2.04(a)(ii), any part of the Euro-Rate Portion for which such notice is not
received shall be converted automatically to the Base Rate Option on the last
day of the expiring Funding Period.

                  2.05.  PREPAYMENTS GENERALLY.

                  (a) GENERAL PROCEDURE FOR PREPAYMENTS. Subject to the
provisions of this Agreement, whenever the Borrower desires or is required to
prepay any part of the Committed Loans, it shall provide Standard Notice to the
Administrative Agent setting forth the following information (a separate notice
being required for Revolving Credit Loans and Term Loans, specifying the type of
Loans to which such notice applies):


                                      -7-
<PAGE>   20


                  (i) The date, which shall be a Business Day, on which the
proposed prepayment is to be made;

                  (ii) The total principal amount of such prepayment, which
         shall be the sum of the principal amounts selected pursuant to clause
         (iii) of this Section 2.05(a), and which shall be an integral multiple
         of $1,000,000 not less than $10,000,000 (unless such prepayment repays
         all of the outstanding Revolving Credit Loans or all of the outstanding
         Term Loans, as the case may be) and;

                  (iii) The principal amounts selected in accordance with
         Section 2.03(d) of the Base Rate Portion and each part of each Funding
         Segment of the Euro-Rate Portion to be prepaid.

Standard Notice having been so provided, on the date specified in such Standard
Notice, the principal amounts specified in such notice, together with interest
on each such principal amount to such date, shall be due and payable.

                  (b) APPLICATION OF TERM LOAN PREPAYMENTS TO SCHEDULED
AMORTIZATION. Except as provided in Section 2.06, prepayments of the Term Loans
shall be applied to the remaining scheduled installments of the Term Loans set
forth in Section 2.01(b)(iii) in the inverse order of their scheduled
maturities.

                  2.06. OPTIONAL PREPAYMENT OF COMMITTED LOANS. The Borrower
shall have the right at its option from time to time to prepay Committed Loans
in whole or part without premium or penalty (subject, however, to Section
2.10(b)):

                  (a) At any time with respect to any part of the Base Rate 
         Portion; or

                  (b) At the expiration of any Funding Period with respect to
         prepayment of the Euro-Rate Portion with respect to any part of the
         Funding Segment corresponding to such expiring Funding Period.

Any such prepayment shall be made in accordance with Section 2.05. Prepayments
of the Term Loans pursuant to this Section 2.06 shall be applied to the
remaining scheduled installments of the Term Loans set forth in Section
2.01(b)(iii) ratably in proportion to the amounts of such remaining scheduled
installments.

                  2.07. MANDATORY PREPAYMENTS AND MANDATORY REDUCTIONS OF THE 
COMMITMENTS.

                  (a) REVOLVING CREDIT COMMITTED AMOUNTS. If on any day the
aggregate Revolving Credit Usages of the Lenders exceeds the aggregate Revolving
Credit Committed Amounts, the Borrower shall prepay (and, to the extent required
by Section 3.01(g), provide cash collateral with respect to) the Revolving
Credit Usages in an aggregate principal amount not less than the amount of such
excess. Such amount shall be applied first to the principal amount of
outstanding Swingline Loans, then to outstanding Letter of Credit Unreimbursed
Draws, then to the principal amount of outstanding Revolving Credit Loans, then
to the principal amount of outstanding Competitive Bid Loans, and the balance
shall be deposited into the Letter of Credit Collateral Account. Any such
prepayments and cash collateralization shall be immediately due and payable on
such day, without presentment, demand, protest or notice of any kind. Subject to
the foregoing provision on priority of application, such prepayments shall be
allocated among the Portions of the Revolving Credit Loans, among Funding
Segments of the Euro-Rate Portion of the 


                                      -8-
<PAGE>   21


Revolving Credit Loans, among Funding Segments of the As-Offered Rate Portions
of the Swingline Loans, and among the Competitive Bid Loans, as the Borrower may
designate or, absent such designation, as determined by the Administrative
Agent.

                  (b)  REDUCTION EVENTS.

                  (i) GENERALLY. "Reduction Event" shall mean any of the events
defined as such in Section 2.07(b)(ii), (iii), (iv), (v) or (vi). If a Reduction
Event shall occur, an amount not less than the corresponding Reduction Event
Application Amount shall be applied (x) first, to prepayment of the unpaid
principal amount of outstanding Term Loans, if any, and then (y) the balance, if
any, shall be applied to reduction of the aggregate Revolving Credit Committed
Amounts; provided, that the Borrower shall not be obligated to make any
application pursuant to the foregoing clause (y) in the event that (A) the
Investment Grade Rating Condition is satisfied on the Reduction Event Date
corresponding to such Reduction Event, or (B) such Reduction Event is under
Section 2.07(b)(vi) (relating to Excess Cash Flow). Any such prepayment of the
Term Loans shall be made in accordance with Section 2.05. Any such reduction of
the Revolving Credit Committed Amounts shall be made in accordance with Section
2.01(a)(v)(C), and if such reduction causes the aggregate Revolving Credit
Usages of the Lenders to exceed the aggregate Revolving Credit Committed
Amounts, the Borrower shall prepay (and, to the extent required by Section
3.01(g), provide cash collateral with respect to) such excess in accordance with
Section 2.07(a), and to the extent possible, the Borrower shall make prepayment
in accordance with Sections 2.05 and 3.02 not later than the effective date of
such reduction so as to avoid such excess. Such prepayments of the Term Loans
and reductions of the Revolving Credit Committed Amounts shall be made not later
than the Reduction Event Date corresponding to such Reduction Event, provided,
that

                  (A) if the Reduction Event Application Amount in respect of
         such Reduction Event is less than $10,000,000, such prepayment and
         reduction shall not be required until the aggregate amount of all
         Reduction Event Application Amounts not applied are equal to at least
         $10,000,000; and

                  (B) if application of this Section 2.07(b) would otherwise
         require prepayment of any Funding Segment of any Euro-Rate Portion or
         any Competitive Bid Loan on a day other than the last day of the
         corresponding Funding Period, then such prepayment shall, unless the
         Administrative Agent otherwise notifies the Borrower upon the
         instructions of the Required Lenders, be deferred until such last day;
         provided, that (x) in no event may prepayments be deferred pursuant to
         this clause (B) for longer than 90 days, and (y) deferral of
         prepayments under this clause (B) shall not apply to Reduction Events
         described in Section 2.07(b)(vi) (relating to Excess Cash Flow).

The Borrower shall give the Administrative Agent at least three Business Days'
notice of each prepayment or reduction required to be made pursuant to this
Section 2.07(b), and of each event which would give rise to such a prepayment or
reduction but for application of the foregoing clauses (A) or (B).

                  (ii) ASSET SALES. "Reduction Event" shall include the
following (each, a "Reduction Event Asset Sale"): any sale, lease or other
disposition (including without limitation (x) any such transaction effected by
way of merger or consolidation, and (y) any sale-leaseback transaction whether
or not involving a capitalized lease) by the Borrower or any of its Subsidiaries
of any property (including without limitation any capital stock or other equity
interest held by the Borrower or such Subsidiary), but excluding (A) any
disposition to the Borrower or to a Subsidiary of the Borrower, (B) any sale,
transfer or other disposition in the ordinary course of business of inventory or
of obsolete equipment or equipment which has been replaced by upgraded equipment
(it being understood that dispositions of equipment which has 


                                      -9-
<PAGE>   22


become redundant as a result of the Acquisition or any other acquisition of a
business shall not be deemed to be in the ordinary course), (C) any sale, lease
or other disposition (or series of related sales, leases or other dispositions)
the Net Proceeds of which do not exceed $5,000,000, (D) any leases of tangible
personal property entered into in the ordinary course of business, (E) any sale,
transfer or other disposition of temporary cash investments in the ordinary
course of business, (F) any sale, transfer or other disposition of any property
if the Borrower notifies the Administrative Agent promptly after the receipt of
the Net Proceeds thereof that such proceeds will be used by the Borrower and its
Subsidiaries to purchase similar properties within twelve months after the date
of such notice, but only to the extent such proceeds are actually so used, (G)
any sale, transfer or other disposition of any Margin Stock for fair value on or
before the Merger Date (provided, that if the proceeds thereof are not applied
to the Loan Obligations, they will be held as cash or cash equivalent
investments), (H) any disposition in a Reduction Event described in Section
2.07(b)(iii), (I) any leases or subleases of unoccupied space, and (J) any
factorings permitted by Section 7.07(z) The "Reduction Event Application Amount"
corresponding to the foregoing Reduction Event shall be 100% of the Net Proceeds
thereof. The "Reduction Event Date" corresponding to the foregoing Reduction
Event shall be five Business Days after the Borrower or its Subsidiaries
receives Net Proceeds from such event.

                  (iii) EXTRAORDINARY INSURANCE PROCEEDS. "Reduction Event"
shall include the following: receipt of (i) aggregate insurance proceeds in
excess of $5,000,000 in connection with one or more related events by the
Borrower or any of its Subsidiaries under any insurance policy covering losses
with respect to tangible real or personal property or improvements, or (ii) any
award or other compensation in excess of such amount in connection with one or
more related events of condemnation of property (or transfer or disposition in
lieu of condemnation) of the Borrower or any of its Subsidiaries; provided, that
receipt of such proceeds, award or other compensation shall not be considered as
giving rise to a Reduction Event if the Borrower notifies the Administrative
Agent promptly after such receipt thereof that such proceeds, award or other
compensation will be used by the Borrower and its Subsidiaries to repair or
replace the asset so affected within twelve months after the date of such
notice, but only to the extent that such proceeds, award or other compensation
is actually so used. The "Reduction Event Application Amount" corresponding to
the foregoing Reduction Event shall be 100% of the Net Proceeds thereof. The
"Reduction Event Date" corresponding to the foregoing Reduction Event shall be
five Business Days after the Borrower or its Subsidiaries receives Net Proceeds
from such event.

                  (iv) EQUITY ISSUANCE. "Reduction Event" shall include the
following: issuance of any equity securities by the Borrower or any of its
Subsidiaries, excluding (A) equity securities issued in consideration for the
acquisition of a business (in each case whether by acquisition of stock or
assets), (B) equity securities issued to the Borrower or any of its
Subsidiaries, (C) directors' qualifying shares, (D) equity securities issued in

Administrative Agent.

law, after there shall have become due (by acceleration or otherwise) principal,

                  (i) In the case of any part of the Euro-Rate Portion of any
         Committed Loans, or any part of the As-Offered Rate Portion of the
         Swingline Loans, or any part of any Competitive Bid Loans, (A) until
         the end of the applicable then-current Funding Period at a rate per

         the rate otherwise applicable to such part, and (B) thereafter in
         accordance with the following clause (ii); and

                  (ii) In the case of any other amount due from the Borrower
         hereunder or under any Loan Document, at a rate per annum (computed on
         the basis of a year of 365 or 366 days, as the case may be, and actual
         days elapsed) 2.00% above the then-current Base Rate Option.

                  2.10.  ADDITIONAL COMPENSATION IN CERTAIN CIRCUMSTANCES.

                  (a) INCREASED COSTS OR REDUCED RETURN RESULTING FROM RESERVES,
CAPITAL ADEQUACY REQUIREMENTS, EXPENSES, ETC. If any Law or guideline or
interpretation or application thereof by any Governmental Authority charged with
the interpretation or administration thereof or compliance with any request or
directive of any Governmental Authority (whether or not having the force of law)
adopted (x) on or after the related Competitive Bid Quote, in the case of a
Competitive Bid Loan, or (y) on or after the date hereof, in the case of any
other matter referred to in this Section 2.10(a)

                  (i) imposes, modifies or deems applicable any reserve, special
         deposit, insurance assessment or any other requirement against credits
         or commitments to extend credit extended by, assets (funded or
         contingent) of, deposits with or for the account of, or other
         acquisitions of funds by, any Lender Party or its Applicable Lending
         Office (other than requirements expressly included herein in the
         determination of the Euro-Rate hereunder),

                  (ii) imposes, modifies or deems applicable any capital
         adequacy or similar requirement against assets (funded or contingent)
         of, or credits or commitments to extend credit extended by, 


                                      -12-
<PAGE>   25

          any Lender Party or its Applicable Lending Office, or applicable to
          the obligations of any Lender Party or its Applicable Lending Office
          under or in connection with any Loan Document, or

                  (iii) imposes upon any Lender Party or its Applicable Lending
         Office any other condition or expense with respect to any Loan Document
         or its making, maintenance or funding of any Loan, Letter of Credit,
         Letter of Credit Participating Interest or Swingline Loan Participating
         Interest,

and the result of any of the foregoing is to increase the cost to, reduce the
income receivable by, or impose any expense (including loss of margin) upon any
Lender Party or its Applicable Lending Office or, in the case of clause (ii),
any Person controlling a Lender Party, with respect to any Loan Document or the
making, maintenance or funding of any Loan, Letter of Credit, Letter of Credit
Participating Interest or Swingline Loan Participating Interest (or, in the case
of any capital adequacy or similar requirement, to have the effect of reducing
the rate of return on capital of such Lender Party, Applicable Lending Office or
controlling Person's capital, taking into consideration the policies of such
Lender Party, Applicable Lending Office or controlling Person with respect to
capital adequacy) by an amount which such Lender Party deems to be material
(such Lender Party being deemed for this purpose to have made, maintained or
funded each Funding Segment of the Euro-Rate Portion from a Corresponding Source
of Funds), such Lender Party may from time to time notify the Borrower of the
amount (determined in good faith by such Lender Party) necessary to compensate
such Lender Party, Applicable Lending Office or controlling Person for such
increase, reduction or imposition. A certificate of a Lender Party claiming
compensation under this Section 2.10(a) and setting forth the additional amount
to be paid to it and indicating in reasonable detail the computation thereof
shall be conclusive absent manifest error. In making any such computation such
Lender Party may take into account any special, supplemental or other
nonrecurring items, may apply any reasonable averaging or attribution methods,
and may make such computation prospectively or retrospectively. Such amount
shall be due and payable by the Borrower to such Lender Party ten Business Days
after such certificate is given. The Borrower shall not be liable under this
Section 2.10(a) to any Lender Party to compensate it or any controlling Person
of such Lender Party for any cost, reduction or imposition incurred or suffered
more than 90 days before receipt by the Borrower of a notice from such Lender
Party referring to the event that gave rise to such cost, reduction or
imposition.

                  (b) FUNDING BREAKAGE. In the event that for any reason (i) the
Borrower fails to borrow, convert or renew any part of any Loan which would,
after such borrowing, conversion or renewal, have a Euro-Rate Portion or
As-Offered Rate Portion, or fails to borrow any part of any Competitive Bid
Loan, in each instance after notice requesting such borrowing, conversion or
renewal has been given by the Borrower (whether such failure results from
failure to satisfy applicable conditions to such borrowing, conversion or
renewal or otherwise), or (ii) any part of any Funding Segment of any Euro-Rate
Portion or As-Offered Rate Portion, or any part of any Competitive Bid Loan,
becomes due (by acceleration or otherwise), or is paid, prepaid or converted to
another interest rate Option (whether or not such payment, prepayment or
conversion is mandatory or automatic and whether or not such payment or
prepayment is then due), on a day other than the last day of the corresponding
Funding Period, the Borrower shall indemnify each Lender on demand (following
delivery by such Lender to the Borrower of the certificate referred to below)
against any loss, liability, cost or expense of any kind or nature which such
Lender may sustain or incur in connection with or as a result of such event.
Such indemnification in any event shall include an amount equal to the excess,
if any, of (x) the aggregate amount of interest which would have accrued on the
amount of the Euro-Rate Portion, As-Offered Rate Portion or Competitive Bid Loan
not so borrowed, converted or renewed, or which so becomes due, or which is so
paid, prepaid or converted, as the case may be, from and including the date on
which such borrowing, conversion or renewal would have been made pursuant to
such notice, or on which such part of such Funding Segment or such part of such
Competitive Bid Loan so becomes due, or on which such part of such Funding
Segment or such part of 


                                      -13-
<PAGE>   26


such Competitive Bid Loan is so paid, prepaid or converted, as the case may be,
to the last day of the Funding Period applicable to such amount (or, in the case
of a failure to borrow, convert or renew, the Funding Period that would have
been applicable to such amount but for such failure), in each case at the
applicable rate of interest for such Euro-Rate Portion provided for herein
(excluding, however, the Applicable Margin included therein, if any), or the
applicable As-Offered Rate, or the applicable Competitive Bid Rate, as the case
may be, over (y) the aggregate amount of interest (as determined in good faith
by such Lender) which would have accrued to such Lender on such amount for such
period by placing such amount on deposit for such period with leading banks in
the interbank market. A certificate of a Lender Party claiming compensation
under this Section 2.10(b) and setting forth the additional amount to be paid to
it and indicating in reasonable detail the computation thereof shall be
conclusive absent manifest error.

                  2.11. TAXES.

                  (a) PAYMENT NET OF TAXES. All payments made by the Borrower
under this Agreement or any other Loan Document shall be made free and clear of,
and without reduction or withholding for, any and all present or future taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, and all
liabilities with respect thereto, excluding (x) in the case of each Lender
Party, net income taxes imposed on such Lender Party by the United States, and
net income taxes and franchise taxes imposed on such Lender Party by the
jurisdiction under the laws of which such Lender Party is organized or by any
political subdivision thereof, and (y) in the case of each Lender, net income
taxes and franchise taxes imposed on such Lender by the jurisdiction in which
the Lender's Applicable Lending Office is located or any political subdivision
thereof (all such non-excluded taxes, levies, imposts, deductions, charges or
withholdings being hereinafter called "Taxes"). If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable under
this Agreement or any Loan Document to any Lender Party, (i) the sum payable
shall be increased as may be necessary so that after making all required
deductions (including without limitation deductions applicable to additional
sums payable under this Section 2.11) such Lender Party receives an amount equal
to the sum it would have received had no such deductions been made, (ii) the
Borrower shall make such deductions, and (iii) the Borrower shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

                  (b) OTHER TAXES. The Borrower agrees 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 under this Agreement or any
other Loan Document or from the execution, delivery of, or otherwise with
respect to , this Agreement or any other Loan Document (hereinafter referred to
as "Other Taxes").

                  (c) INDEMNITY. The Borrower hereby indemnifies each Lender
Party for the full amount of all Taxes and Other Taxes (including without
limitation any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 2.11 paid by such Lender Party and any liability
(including without limitation penalties, interest and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted. Such indemnification shall be made within 15 days
after the date such Lender Party makes demand therefor (which demand shall
identify in reasonable detail the nature and the amount of Taxes and Other Taxes
for which indemnification is being sought).

                  (d) RECEIPTS, ETC. Within 30 days after the date of any
payment of Taxes or Other Taxes, the Borrower will furnish to the Administrative
Agent the original or a certified copy of a receipt evidencing payment thereof.

                  (e) SURVIVAL, ETC. Without prejudice to the survival of any
other obligation of the Borrower under this Agreement or the other Loan
Documents, the obligations of the Borrower contained in this Section 2.11 shall
survive the payment in full of all other obligations of the Borrower under this
Agreement and the other Loan Documents, termination of all commitments to extend
credit under, and all Letters of Credit issued under, the Loan Documents,
termination of this Agreement, and all other events and circumstances whatever.
Nothing in this Section 2.11 or otherwise in this Agreement shall require any
Lender Party to disclose to the Borrower any of its tax returns (or any other
information that it deems to be confidential or proprietary).

                  (f)  WITHHOLDING TAX EXEMPTION.

                  (i) PROVISION OF FORMS. Each Lender organized under the laws
of a jurisdiction outside the United States shall, on or prior to the date it
becomes party to this Agreement, and from time to time thereafter if requested
in writing by the Borrower or the Administrative Agent, provide the Borrower and
the Administrative Agent each with an original Internal Revenue Service Form
1001 or 4224, as appropriate, or any successor form prescribed by the Internal
Revenue Service, certifying such Lender's status for purposes of determining
exemption from, or reduced rate applicable to, United States withholding taxes
with respect to such Lender under this Agreement and the other Loan Documents;
provided, that a Lender shall not be obligated to provide any such form after
the date such Lender becomes party to this Agreement if such Lender is not
legally able to do so.

                  (ii) INDEMNIFICATION LIMITED IN CERTAIN CIRCUMSTANCES. The
Borrower shall not be required to indemnify any Lender, or to pay any additional
amounts to any Lender, in respect of United States withholding taxes (or any
withholding tax imposed by a state of the United States that applies only when
such United States withholding tax is imposed), pursuant to Section 2.11(a) or
2.11(c), to the extent that (A) the obligation to withhold amount with respect
to United States withholding tax existed on the date such Lender became a party
to this Agreement; provided, that this clause (A) shall not apply to a Lender
that became a Lender as an result of an assignment made or other action taken at
the request of the Borrower, or (B) the obligation to make such indemnification
or to pay such additional amount would not have arisen but for a failure of such
Lender to comply with the provisions of Section 2.11(f)(i).

                  2.12. CHANGE OF APPLICABLE LENDING OFFICE. In the event that a
Lender becomes an Affected Lender under Section 2.03(e)(ii), or in the event
that a Lender requests compensation from the Borrower pursuant to Section
2.10(a) or 2.11, then, at the request of the Borrower, such Lender will change
the jurisdiction of its Applicable Lending Office if, in the judgment of such
Lender, such change will eliminate or mitigate a similar event which may
thereafter accrue and is not otherwise materially disadvantageous to such
Lender.

                  2.13. SUBSTITUTION OF LENDER. In the event that a Lender
becomes an Affected Lender under Section 2.03(e), or in the event that a Lender
requests compensation from the Borrower pursuant to Section 2.10(a) or 2.11,
then, if the Borrower designates one or more substitute institutions to purchase
the Loans and assume the Commitments of such Lender, such Lender will at the
Borrower's request sell its Loans and assign its rights under this Agreement to
such substitute institutions with reasonable promptness after such designation
in accordance with Section 10.14(c) for a payment equal to the principal amount
of its Loans, plus all accrued and unpaid interest and fees to but excluding the
date of purchase, plus any other amounts accrued or payable to such Lender under
this Agreement to but excluding the date of purchase, plus any amount that would
be payable to such Lender under Section 2.10(b) (as if such purchase were
treated as a prepayment of the outstanding Loans to such Lender), together with
any other loss or expense incurred by it (or by a Participant in the related
Loan or Commitment). Nothing in this 


                                      -15-

Section 2.13 limits the rights of the Administrative Agent, the Swingline Lender
or the Issuing Bank Representative under Section 10.14(c) or any other provision
of the Loan Documents.


                                   ARTICLE III
                       THE REVOLVING CREDIT SUBFACILITIES

                  3.01. THE LETTER OF CREDIT SUBFACILITY.

                  (a) THE LETTER OF CREDIT SUBFACILITY.

                  (i) GENERAL. Subject to the terms and conditions of this
Agreement, and relying upon the representations and warranties herein set forth
and upon the agreements of the Lenders set forth in Sections 3.01(c) and
3.01(d), the Issuing Bank Representative agrees (such agreement being herein
called the "Letter of Credit Commitment") to cause the Issuing Banks to issue
for the account of the Borrower letters of credit (each, as amended, modified or
supplemented from time to time, a "Letter of Credit") at any time or from time
to time on or after the date hereof. The Borrower shall not request any Letter
of Credit to be issued except within the following limitations: (i) no Letter of
Credit shall be issued later than 90 days before the Revolving Credit Maturity
Date, (ii) no Letter of Credit shall be issued if the Administrative Agent shall
have received the notice from the Required Lenders referred to in Section
3.01(b)(iii)(C), (iii) at the time any Letter of Credit is issued, the aggregate
Revolving Credit Usages of the Lenders (after giving effect to issuance of the
requested Letter of Credit) shall not exceed the sum of the Revolving Credit
Committed Amounts of the Lenders at such time, and (iv) on the date of issuance
of any Letter of Credit (and after giving effect to such issuance) the aggregate
Letter of Credit Exposure shall not exceed $50,000,000.

                  (ii) TERMS OF LETTERS OF CREDIT. The Borrower shall not
request any Letter of Credit to be issued except within the following

than the earlier of (A) 12 months after the date of issuance thereof, or (B) ten
days before the Revolving Credit Maturity Date, (ii) shall not be an evergreen
Letter of Credit, (iii) shall be denominated in Dollars, and (iv) shall be
payable only against sight drafts (and not time drafts).

                  (iii) PURPOSES OF LETTERS OF CREDIT. Each Letter of Credit
shall be satisfactory in form and substance to the relevant Issuing Bank. Each
Letter of Credit shall be a trade or standby letter of credit used to support
trade or financial obligations of the Borrower or any of its Subsidiaries. The
provisions of this Section 3.01(a)(iii) represent only an obligation of the
Borrower to the Issuing Banks and the Lenders; no Issuing Bank shall have any
obligation to the Lenders to ascertain the purpose of any Letter of Credit, and
the rights and obligations of the Lenders and the Issuing Banks among themselves
shall not be impaired or affected by a breach of this Section 3.01(a)(iii).

                  (iv) LETTER OF CREDIT FEE. The Borrower shall pay to the
Administrative Agent for the account of each Lender a fee (the "Letter of Credit
Fee") for each Letter of Credit for each day from and including the date of
issuance thereof to and including the date of expiration or termination thereof,
equal to (x) the Letter of Credit Undrawn Availability on such day, times (y)
the Letter of Credit Fee Rate applicable to such Letter of Credit on such day,
times (z) 1/360. Such Letter of Credit Fee shall be due and payable for the
preceding period for which such fee has not been paid on each of the following
dates: (i) each Regular Payment Date, and (ii) the Revolving Credit Maturity
Date. The "Letter of Credit Fee Rate" applicable to a Letter of Credit on any
day means (A) if such Letter of Credit is a commercial letter of credit for the
purpose of providing a payment mechanism in connection with the purchase of
goods or 


                                      -16-
<PAGE>   29


services by the Borrower or any of its Subsidiaries (and, as such, is eligible
to be categorized for capital purposes as a "short-term, self-liquidating
trade-related contingency, including commercial letters of credit," as such
phrase is used in the risk-based capital regulations issued by the Office of the
Comptroller of the Currency as in effect on the date hereof, or any successor
category of similar import), then the Letter of Credit Fee Rate shall be
one-half of the Applicable Margin under the Euro-Rate Option on such day, (B)
otherwise, the Letter of Credit Fee Rate shall be the Applicable Margin under
the Euro-Rate Option on such day.

                  (v) FACING FEE; ADMINISTRATION FEES. The Borrower shall pay to
the Administrative Agent, for the sole account of the relevant Issuing Bank, a
fee (the "Letter of Credit Facing Fee") for each Letter of Credit for each day
from and including the date of issuance thereof to and including the date of
expiration or termination thereof, equal to (x) the Letter of Credit Undrawn
Availability on such day, times (y) 0.125%, times (z) 1/360. Such Letter of
Credit Facing Fee shall be due and payable for the preceding period for which
such fee has not been paid on the same dates as payments of the Letter of Credit
Fee with respect to such Letter of Credit. In addition, the Borrower shall pay
to the Administrative Agent, for the sole account of the Issuing Bank, such
other administration, maintenance, amendment, drawing and negotiation fees as
may be customarily charged by the Issuing Bank from time to time in connection
with letters of credit.

                  (vi) PRIOR LETTERS OF CREDIT. Each letter of credit (each, a
"Prior Letter of Credit") identified on Schedule 3.01(a)(vi) which has been
issued by a Lender who is party hereto on the Closing Date and which is
outstanding on the Closing Date shall, as of the Closing Date, automatically and
without further action be deemed to be a Letter of Credit issued under this
Agreement. The Borrower hereby represents and warrants that such Prior Letters
of Credit will comply with the limitations set forth in Sections 3.01(a)(i) and
3.01(a)(ii) as of the Closing Date as if issued hereunder on the Closing Date.
Fees with respect to such Prior Letters of Credit for each day to and including
the Closing Date shall accrue at the rates previously agreed to by the Borrower
and the relevant issuing bank, and shall be payable on the Closing Date (or at
such other time as the Borrower and the relevant issuing bank may agree), and
fees with respect to such Prior Letters of Credit for each day after the Closing
Date shall accrue and be payable as provided for Letters of Credit in this
Agreement. Notwithstanding anything to the contrary in this Agreement, any
Lender (other than the Issuing Bank Representative and its Affiliates) which
acts as Issuing Bank for any Prior Letter of Credit (A) shall have no obligation
to extend or renew any Prior Letter of Credit, (B) shall not extend or renew any
Prior Letter of Credit without the consent of the Administrative Agent and the
Issuing Bank Representative in their respective discretion and (C) shall be
justified and fully protected in extending or renewing any Prior Letter of
Credit if it has received such consent.

                  (b) PROCEDURE FOR ISSUANCE AND AMENDMENT OF LETTERS OF CREDIT.

                  (i) REQUEST FOR ISSUANCE. The Borrower may from time to time
request, upon at least three Business Days' notice, the Issuing Bank
Representative to cause an Issuing Bank to issue a Letter of Credit by (i)
delivering to the Issuing Bank Representative (or such other Issuing Bank as the
Issuing Bank Representative may from time to time designate) and the
Administrative Agent a written request to such effect, specifying the date on
which such Letter of Credit is to be issued, the expiration date thereof, and
the stated amount thereof, and (ii) delivering to the Issuing Bank an
application, in such form as the Issuing Bank may from time to time require
(each, a "Letter of Credit Application"), completed to the satisfaction of the
Issuing Bank, together with such other certificates, documents and other items
as such Issuing Bank may request. If the Issuing Bank desires to issue such
Letter of Credit, the Issuing Bank shall promptly notify the Administrative
Agent (by telephone or otherwise), and furnish the Administrative Agent with 


                                      -17-
<PAGE>   30

the proposed form of Letter of Credit to be issued. The Administrative Agent
shall determine, as of the close of business on the day before such proposed
issuance, whether such proposed Letter of Credit complies with the limitations
set forth in Sections 3.01(a)(i) and 3.01(a)(ii). Unless such limitations are
not satisfied, or unless the Required Lenders have given notice to the
Administrative Agent to cease issuing Letters of Credit pursuant to Section
3.01(b)(iii)(C), the Administrative Agent shall notify the relevant Issuing Bank
(in writing or by telephone promptly confirmed in writing) that such Issuing
Bank is authorized to issue such Letter of Credit. If the Issuing Bank issues a
Letter of Credit, it shall deliver the original of such Letter of Credit to the
beneficiary thereof or as the Borrower shall otherwise direct, and shall
promptly notify the Administrative Agent thereof, and if the Administrative
Agent so requests shall furnish a copy thereof to the Administrative Agent.

                  (ii) EXTENSION OR INCREASE. The Borrower may from time to time
request an Issuing Bank to extend the expiration date of an outstanding Letter
of Credit issued by such Issuing Bank or to increase the Letter of Credit
Undrawn Availability of such Letter of Credit. Such extension or increase shall
for all purposes hereunder (including Sections 3.01(a), 3.01(b)(i) and 5.02) be
treated as though the Borrower had requested issuance of a replacement Letter of
Credit; provided, that the Issuing Bank may, if it elects, issue an amendment to
the Letter of Credit providing for such an extension or increase in lieu of
issuing a new Letter of Credit in substitution therefor.

                  (iii) LIMITATIONS ON ISSUANCE, EXTENSION AND AMENDMENT.

                  (A) As between the Borrower, on the one hand, and the Lender
Parties, on the other hand, the issuance or extension of any Letter of Credit
(including any deemed issuance arising from increase or extension of a Letter of
Credit as provided in Section 3.01(b)(ii)) is subject to the applicable
conditions precedent set forth or referred to in this Section 3.01 and Articles
V and VIII. In addition, each Issuing Bank shall be justified and fully
protected in declining to issue or extend any Letter of Credit (including any
deemed issuance) if the Issuing Bank has not received authorization to do so
from the Administrative Agent as provided in Section 3.01(b)(i).

                  (B) As between each Issuing Bank, on the one hand, and the
Administrative Agent and the Lenders, on the other hand, such Issuing Bank shall
be justified and fully protected in issuing any Letter of Credit (including any
deemed issuance arising from increase or extension of a Letter of Credit as
provided in Section 3.01(b)(ii)) after receiving authorization from the
Administrative Agent as provided in Section 3.01(b)(i), notwithstanding any
subsequent notices to the Issuing Bank, any knowledge of an Event of Default or
Potential Default, any knowledge of failure of any applicable condition set
forth or referred to in this Section 3.01 or Articles V or VIII to be satisfied,
any other knowledge of the Issuing Bank, or any other event, condition or
circumstance whatever.

                  (C) As between the Administrative Agent, on the one hand, and
the Lenders, on the other hand, the Administrative Agent shall not authorize
issuance of any Letter of Credit pursuant to Section 3.01(b)(i) (including any
deemed issuance arising from increase or extension of a Letter of Credit as
provided in Section 3.01(b)(ii)) if the Administrative Agent shall have
received, at least two Business Days before authorizing such issuance, from the
Required Lenders an unrevoked written notice that any applicable condition set
forth or referred to in this Section 3.01 or Article V or VIII will not be
satisfied and expressly requesting that the Administrative Agent direct the
Issuing Banks to cease to issue Letters of Credit. Unless the Administrative
Agent has received such notice or has determined that the applicable limitations
set forth in Sections 3.01(a)(i) and 3.01(a)(ii) are not satisfied, the
Administrative Agent shall be justified and fully protected, as against the
Lenders, in authorizing the Issuing Bank to issue such Letter of Credit,
notwithstanding any subsequent notices to the Administrative Agent, any
knowledge of an Event 


                                      -18-
<PAGE>   31

of Default or Potential Default, any knowledge of failure of any applicable
condition set forth or referred to in this Section 3.01 or Article V or VIII to
be satisfied, any other knowledge of the Administrative Agent, or any other
event, condition or circumstance whatever.

                  (iv) AMENDMENTS. At the request of the Borrower from time to
time, and subject to satisfaction of such conditions as the relevant Issuing
Bank may require, each Issuing Bank may amend, modify or supplement Letters of
Credit, or waive compliance with any condition of issuance or payment, without
the consent of, and without liability to, the Administrative Agent or any
Lender; provided, that any such amendment, modification or supplement that
extends the expiration date or increases the Letter of Credit Undrawn
Availability of an outstanding Letter of Credit shall be subject to Section
3.01(b)(ii).

                  (c) LETTER OF CREDIT PARTICIPATING INTERESTS.

                  (i) GENERALLY. Concurrently with the issuance of each Letter
of Credit, the relevant Issuing Bank automatically shall be deemed, irrevocably
and unconditionally, to have sold, assigned, transferred and conveyed to each
other Lender, and each other Lender automatically shall be deemed, irrevocably
and unconditionally, severally to have purchased, acquired, accepted and assumed
from the Issuing Bank, without recourse to, or representation or warranty by,
the Issuing Bank, an undivided interest, in a proportion equal to such Lender's
Pro Rata share, in all of the Issuing Bank's rights and obligations in, to or
under such Letter of Credit, the Letter of Credit Application, the Letter of
Credit Reimbursement Obligations, and all collateral, guarantees and other
rights from time to time directly or indirectly securing the foregoing (such
interest of each Lender being referred to herein as a "Letter of Credit
Participating Interest"). Amounts other than Letter of Credit Reimbursement
Obligations and Letter of Credit Fees payable from time to time under or in
connection with a Letter of Credit or a Letter of Credit Application shall be
for the sole account of the relevant Issuing Bank. On the date that any
Purchasing Lender becomes a party to this Agreement in accordance with Section
10.14, Letter of Credit Participating Interests in any outstanding Letters of
Credit held by the Lender from which such Purchasing Lender acquired its
interest hereunder shall be proportionately reallocated between such Purchasing
Lender and such transferor Lender (and, to the extent such transferor Lender is
an Issuing Bank, the Purchasing Lender shall be deemed to have acquired a Letter
of Credit Participating Interest from such transferor Lender to such extent).

                  (ii) OBLIGATIONS ABSOLUTE. Notwithstanding any other provision
hereof, each Lender hereby agrees that its obligation to participate in each
Letter of Credit issued in accordance herewith, and its obligation to make the
payments specified in Section 3.01(d), are each absolute, irrevocable and
unconditional and shall not be affected by any event, condition or circumstance
whatever. The failure of any Lender to make any such payment shall not relieve
any other Lender of its funding obligation hereunder on the date due, but no
Lender shall be responsible for the failure of any other Lender to meet its
funding obligations hereunder.

                  (d) LETTER OF CREDIT DRAWINGS AND REIMBURSEMENTS.

                  (i) BORROWER'S REIMBURSEMENT OBLIGATION. The Borrower hereby
agrees to reimburse the Issuing Bank, by making payment to the Administrative
Agent for the account of the Issuing Bank in accordance with Section 2.09(b), on
the date and in the amount of each payment made by such Issuing Bank under any
Letter of Credit, upon notice (which may be by telephone) by the Issuing Bank to
the Borrower of such payment, without further notice, protest or demand, all of
which are hereby waived, and an action therefor shall thereupon immediately
accrue. To the extent such payment is not timely made, the Borrower hereby
agrees to pay to the Administrative Agent, for the account of the relevant
Issuing Bank, 


                                      -19-
<PAGE>   32

on demand, interest on any Letter of Credit Unreimbursed Draws for each day from
and including the date of such payment by such Issuing Bank until reimbursed in
full (before and after judgment), in accordance with Section 2.09(c), at the
rate per annum set forth in Section 2.09(c)(ii).

                  (ii) PAYMENT BY LENDERS ON ACCOUNT OF UNREIMBURSED DRAWS. If
an Issuing Bank makes a payment under any Letter of Credit and is not reimbursed
in full therefor on such payment date in accordance with Section 3.01(d)(i),
such Issuing Bank will promptly notify the Administrative Agent thereof (which
notice may be by telephone), and the Administrative Agent shall forthwith notify
each Lender (which notice may be by telephone promptly confirmed in writing)
thereof. No later than the Administrative Agent's close of business on the date
such notice is given, each such Lender will pay to the Administrative Agent, for
the account of such Issuing Bank, in immediately available funds, an amount
equal to such Lender's Pro Rata share of the unreimbursed portion of such
payment by such Issuing Bank. If and to the extent that any Lender fails to make
such payment to the Administrative Agent for the account of such Issuing Bank on
such date, such Lender shall pay such amount on demand, together with interest,
for such Issuing Bank's own account, for each day from and including the date of
such Issuing Bank's payment to and including the date of payment to the Issuing
Bank (before and after judgment) at the following rates per annum: (x) for each
day from and including the date of such payment by the Issuing Bank to and
including the second Business Day thereafter, at the Federal Funds Effective
Rate for such day, and (y) for each day thereafter, at the rate applicable to
Letter of Credit Unreimbursed Draws under Section 3.01(d)(i) for such day.

                  (iii) DISTRIBUTIONS TO PARTICIPANTS. If, at any time, after an
Issuing Bank has made a Letter of Credit Unreimbursed Draw and has received from
any Lender such Lender's share of such Letter of Credit Unreimbursed Draw, such
Issuing Bank receives any payment or makes any application of funds on account
of the Letter of Credit Reimbursement Obligation arising from such Letter of
Credit Unreimbursed Draw, such Issuing Bank will pay to the Administrative
Agent, for the account of such Lender, such Lender's Pro Rata share of such
payment or application.

                  (iv) RESCISSION. If any amount received by an Issuing Bank on
account of any Letter of Credit Reimbursement Obligation shall be avoided,
rescinded or otherwise returned or paid over by such Issuing Bank for any reason
at any time, whether before or after the termination of this Agreement (or such
Issuing Bank believes in good faith that such avoidance, rescission, return or
payment is required, whether or not such matter has been adjudicated), each such
Lender will, promptly upon notice from the Administrative Agent or such Issuing
Bank, pay over to the Administrative Agent for the account of such Issuing Bank
its Pro Rata share of such amount, together with its Pro Rata share of any
interest or penalties payable with respect thereto.

                  (v) EQUALIZATION. If any Lender receives any payment or makes
any application on account of its Letter of Credit Participating Interest, such
Lender shall forthwith pay over to the relevant Issuing Bank, in Dollars and in
like kind of funds received or applied by it the amount in excess of such
Lender's ratable share of the amount so received or applied.

                  (e) OBLIGATIONS ABSOLUTE. The payment obligations of the
Borrower under Section 3.01(d)(i) shall be unconditional and irrevocable and
shall be paid strictly in accordance with the terms of this Agreement under all
circumstances, including, without limitation, the following circumstances:

                  (i) any lack of validity or enforceability of this Agreement,
         any Letter of Credit, any other Loan Document or any documents,
         instruments or agreements evidencing or otherwise relating to 


                                      -20-
<PAGE>   33

         any obligation of the Borrower or Subsidiary of the Borrower secured
         or supported by any Letter of Credit;

                  (ii) the existence of any claim, set-off, defense or other
         right which the Borrower or any other Person may have at any time
         against any beneficiary or transferee of any Letter of Credit (or any
         Persons for whom any such beneficiary or transferee may be acting), the
         relevant Issuing Bank, any Lender, or any other Person, whether in
         connection with this Agreement, the transactions contemplated hereby or
         any unrelated transaction;

                  (iii) any draft, certificate, statement or other document
         presented under any Letter of Credit proving to be forged, fraudulent,
         invalid or insufficient in any respect or any statement therein being
         untrue or inaccurate in any respect;

                  (iv) payment by the Issuing Bank under any Letter of Credit
         against presentation of a draft or certificate which does not comply
         with the terms of such Letter of Credit, or payment by the Issuing Bank
         under the Letter of Credit in any other circumstances in which
         conditions to payment are not met, except any such payment resulting
         solely from the gross negligence or willful misconduct of the Issuing
         Bank; or

                  (v) any other event, condition or circumstance whatever,
         whether or not similar to any of the foregoing.

The Borrower bears the risk of, and neither the Issuing Bank, any of its
directors, officers, employees or agents, nor any Lender, shall be liable or
responsible for the use which may be made of any Letter of Credit, or acts or
omissions of the beneficiary or any transferee in connection therewith.

                  (f) FURTHER ASSURANCES. The Borrower hereby agrees, from time
to time, to do and perform any and all acts and to execute any and all further
instruments reasonably requested by any Issuing Bank more fully to effect the
purposes of this Agreement and the issuance of the Letters of Credit hereunder.
The representations, warranties and covenants by the Borrower under, and rights
and remedies of the Issuing Bank under, any Letter of Credit Application
relating to any Letter of Credit are in addition to, and not in limitation or
derogation of, representations, warranties and covenants by the Borrower under,
and rights and remedies of the Issuing Bank and the Lenders under, this
Agreement, the other Loan Documents, and applicable Law. In the event of any
inconsistency between the terms of this Agreement and any Letter of Credit
Application, this Agreement shall prevail. The terms of this Agreement shall be
deemed to be incorporated by reference into each such agreement or instrument
(whether or not such agreement or instrument so states).

                  (g) CASH COLLATERAL FOR LETTERS OF CREDIT. To the extent that
any provision of this Agreement or any other Loan Document requires a payment,
prepayment or other application of funds to be made with respect to the
Revolving Credit Loans, such provision shall be applied as follows: after
payment in full of the outstanding Revolving Credit Loans and Competitive Bid
Loans (whether or not such payment would require the Borrower to pay any amount
under Section 2.10(b)), and the payment in full of all outstanding Letter of
Credit Unreimbursed Draws, then, to the extent of the excess, if any, of the
aggregate Letter of Credit Exposure at such time over the balance in the Letter
of Credit Collateral Account, an amount equal to the remainder of the amount so
required to be paid by the Borrower shall immediately be paid by the Borrower to
the Collateral Agent for deposit in the Letter of Credit Collateral Account. In
addition, the Borrower agrees that, without limitation of the foregoing or of
any other provisions of this Agreement or the Loan Documents requiring
collateral for the Letters of Credit or other 


                                      -21-
<PAGE>   34

Obligations in whole or in part, and without limitation of other rights and
remedies under this Agreement or the Loan Documents or at law or in equity, if
the Revolving Credit Loans become due and payable pursuant to Section 8.02, the
Borrower shall immediately pay to the Collateral Agent, for deposit in the
Letter of Credit Collateral Account, an amount equal to the excess, if any, of
the aggregate Letter of Credit Exposure at such time over the balance in the
Letter of Credit Collateral Account. The Administrative Agent shall direct the
Collateral Agent to release funds in the Letter of Credit Collateral Account to
the Issuing Bank for payment of Letter of Credit Reimbursement Obligations
constituting Letter of Credit Unreimbursed Draws, as and when the same become
due and payable if and to the extent the Borrower fails to pay the same.

                  (h) CERTAIN PROVISIONS RELATING TO THE ISSUING BANKS.

                  (i) GENERAL. The Issuing Banks shall have no duties or
responsibilities except those expressly set forth in this Agreement and the
other Loan Documents, and no implied duties or responsibilities on the part of
the Issuing Banks shall be read into this Agreement or any Loan Document or
shall otherwise exist. The duties and responsibilities of the Issuing Banks to
the other Lender Parties under this Agreement and the other Loan Documents shall
be mechanical and administrative in nature, and no Issuing Bank shall have a
fiduciary relationship in respect of any Lender Party or any other Person. No
Issuing Bank shall be liable for any action taken or omitted to be taken by it
under or in connection with this Agreement or any other Loan Document, unless
caused by its own gross negligence or willful misconduct. No Issuing Bank shall
be under any obligation to ascertain, inquire or give any notice relating to (i)
the performance or observance of any of the terms or conditions of this
Agreement or any other Loan Document on the part of the Borrower, (ii) the
business, operations, condition (financial or other) or prospects of the
Borrower or any other Person, or (iii) the existence of any Event of Default or
Potential Default. No Issuing Bank shall be under any obligation, either
initially or on a continuing basis, to provide the Administrative Agent or any
Lender with any notices, reports or information of any nature, whether in its
possession presently or hereafter, except for such notices, reports and other
information expressly required by this Agreement to be so furnished.

                  (ii) ADMINISTRATION. Each Issuing Bank may rely upon any
notice or other communication of any nature (written or oral, including but not
limited to telephone conversations, whether or not such notice or other
communication is made in a manner permitted or required by this Agreement or any
Loan Document) purportedly made by or on behalf of the proper party or parties,
and no Issuing Bank shall have any duty to verify the identity or authority of
any Person giving such notice or other communication. Each Issuing Bank may
consult with legal counsel (including, without limitation, in-house counsel for
such Issuing Bank or in-house or other counsel for the Borrower), independent
public accountants and any other experts selected by it from time to time, and
no Issuing Bank shall be liable for any action taken or omitted to be taken in
good faith in accordance with the advice of such counsel, accountants or
experts. Whenever any Issuing Bank shall deem it necessary or desirable that a
matter be proved or established with respect to the Borrower or any Lender
Party, such matter may be established by a certificate of the Borrower or such
Lender Party, as the case may be, and such Issuing Bank may conclusively rely
upon such certificate.

                  (iii) INDEMNIFICATION OF ISSUING BANKS BY LENDERS. Each Lender
hereby agrees to reimburse and indemnify each Issuing Bank and each of their
respective directors, officers, employees and agents (to the extent not
reimbursed by the Borrower and without limitation of the obligations of the
Borrower to do so), Pro Rata, from and against any and all amounts, losses,
liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements of any kind or nature (including,
without limitation, the fees and disbursements of counsel (other than in-house
counsel) for such Issuing Bank or such other Person in connection with any
investigative, administrative or judicial 


                                      -22-
<PAGE>   35

proceeding commenced or threatened, whether or not such Issuing Bank or such
other Person shall be designated a party thereto) that may at any time be
imposed on, incurred by or asserted against such Issuing Bank, in its capacity
as such, or such other Person, as a result of, or arising out of, or in any way
related to or by reason of, this Agreement, any other Loan Document, any
transaction from time to time contemplated hereby or thereby, or any transaction
secured or financed in whole or in part, directly or indirectly, with any Letter
of Credit or the proceeds thereof, provided, that no Lender shall be liable for
any portion of such amounts, losses, liabilities, claims, damages, expenses,
obligations, penalties, actions, judgments, suits, costs or disbursements
resulting from the gross negligence or willful misconduct of such Issuing Bank
or such other Person.

                  3.02. THE SWINGLINE SUBFACILITY.

                  (a) THE SWINGLINE SUBFACILITY.

                  (i) GENERAL. Subject to the terms and conditions of this
Agreement, and relying upon the representations and warranties herein set forth
and upon the agreements of the Lenders set forth in Section 3.02(c), the
Swingline Lender agrees (such agreement being called the "Swingline Commitment")
to make loans (the "Swingline Loans") to the Borrower at any time or from time
to time on or after the date hereof and to but not including the Revolving
Credit Maturity Date. The Swingline Lender shall not make any Swingline Loan to
the extent that the aggregate principal amount of Swingline Loans outstanding
would exceed $50,000,000 (the "Swingline Subfacility Amount"). The Swingline
Lender shall not make any Swingline Loan to the extent that the aggregate amount
of Swingline Loans outstanding would exceed the Swingline Current Availability
most recently notified to it, as more fully provided in Section 3.02(b)(i).

                  (ii) NATURE OF CREDIT. Within the limits of time and amount
set forth in this Section 3.02, and subject to the provisions of this Agreement,
the Borrower may borrow, repay and reborrow Swingline Loans hereunder.

                  (iii) SWINGLINE NOTE. The obligation of the Borrower to repay
the unpaid principal amount of the Swingline Loans made to it by the Swingline
Lender and to pay interest thereon shall be evidenced in part by a promissory
note of the Borrower to the Swingline Lender, dated the date hereof (the
"Swingline Note") in substantially the form attached hereto as Exhibit A-2, with
the blanks appropriately filled, payable to the order of the Swingline Lender in
a face amount equal to the Swingline Subfacility Amount.

                  (iv) MATURITY. To the extent not due and payable earlier, the
Swingline Loans shall be due and payable on the Revolving Credit Maturity Date.

                  (v) MAKING OF SWINGLINE LOANS, ETC. Whenever the Borrower
desires that the Swingline Lender make a Swingline Loan, the Borrower shall
provide notice to the Administrative Agent not later than 12:00 noon, Pittsburgh
time, on the day on which such Swingline Loan is to be made, specifying that
such notice applies to Swingline Loans and specifying (A) the date, which shall
be a Business Day, on which such proposed Swingline Loan is to be made, (B) the
aggregate principal amount of such Swingline Loan (which may be any amount of
$500,000 or more, subject to the overall limitations of time and amount set
forth in this Section 3.02), and (C) the interest rate Option or Options
selected in accordance with Section 3.02(a)(vii) and the principal amounts of
the Base Rate Portion and each Funding Segment of the As-Offered Rate Portion of
such proposed Swingline Loans, and (D) with respect to each Funding Segment of
such proposed Swingline Loans, the Funding Period to apply to such Funding
Segment, selected in accordance with Section 3.02(a)(vii). Subject to the terms
and conditions of this Agreement, on 


                                      -23-
<PAGE>   36

the specified date the Swingline Lender will make the proceeds of such Swingline
Loan available to the Administrative Agent at the Administrative Agent's Office,
no later than 1:00 p.m., in funds immediately available at such Office. The
Administrative Agent will promptly make the funds so received available to the
Borrower in funds immediately available at the Administrative Agent's Office. In
addition, the Swingline Lender may in its discretion from time to time elect to
make Swingline Loans from time to time by paying items presented for payment on,
or otherwise crediting, zero-balance or other accounts maintained with the
Swingline Lender, from time to time without any express request or notice from
the Borrower, it being agreed that (x) the Borrower shall nevertheless be deemed
for all purposes of this Agreement and the other Loan Documents (including but
not limited to Section 5.02) to have made a request for such Swingline Loan as
of the date such item is paid or such credit is made, as the case may be, and
(y) Swingline Loans made in such manner shall bear interest until due at the
Base Rate Option, unless converted to the As-Offered Rate Option in accordance
with Section 3.02(a)(vii).

                  (vi) REPAYMENT OF SWINGLINE LOANS, ETC. The Borrower shall
have the right at its option from time to time to prepay Swingline Loans in
whole or in part at any time in accordance with this Section 3.02(a)(vi)
(subject, however, to Section 2.10(b)). Whenever the Borrower desires or is
required to prepay any part of the Swingline Loans, it shall provide notice to
the Swingline Lender and the Administrative Agent not later than 1:00 p.m.,
Pittsburgh time, on the date of such proposed prepayment, specifying that such
notice applies to Swingline Loans and specifying (A) the date (which shall be a
Business Day) on which the proposed prepayment is to be made, (B) the principal
amount of the Swingline Loans to be prepaid (which may be any amount of $500,000
or more), (C) the allocation of such principal amount to the Base Rate Portion
and to each Funding Segment of the Swingline Loans. Such notice having been
given, on the date specified in such notice the principal amounts specified in
such notice, together with interest on such principal amount to such date, shall
be due and payable. In addition, the Swingline Lender may in its discretion from
time to time elect to apply to repayment of Swingline Loans any amounts on
deposit from time to time in accounts maintained with it (individually or as
Administrative Agent or as Collateral Agent) by or for the benefit of the
Borrower. Any such application may be made without regard to the limitations of
Section 2.05(a). Such applications shall be allocated among the Portions of the
Swingline Loans, and among Funding Segments of the As-Offered Rate Portion, as
determined by the Swingline Lender.

                  (vii) INTEREST RATE ON SWINGLINE LOANS.

                  (A) The unpaid principal amount of the Swingline Loans shall
bear interest for each day until due at the Base Rate Option; provided, however,
that subject to the provisions of this Agreement the Borrower may select the
As-Offered Rate Option to apply to part or all of the outstanding Swingline
Loans for each day until due, it being understood that the Borrower may select
different Options to apply simultaneously to different parts of the Swingline
Loans and may select different Funding Segments to apply simultaneously to
different parts of the As-Offered Rate Portion.

                  (B) At any time when the Borrower shall select, convert to or
renew the As-Offered Rate Option to apply to any part of the Swingline Loans, it
shall fix one or more periods ("As-Offered Rate Funding Periods") during which
such As-Offered Rate Option shall apply. Each As-Offered Rate Funding Period
shall be such period as the Swingline Lender may offer in its sole discretion,
not to exceed seven days; provided, that (x) each As-Offered Rate Funding Period
which would otherwise end on a day which is not a Business Day shall be extended
to the next succeeding Business Day, and (y) any As-Offered Rate Funding Period
which would otherwise end after the Revolving Credit Maturity Date shall end on
the Revolving Credit Maturity Date.

                  (C) Subject to the provisions of Section 2.10(b), the Borrower
may convert any part of the Swingline Loans to the Base Rate Option or the
As-Offered Rate Option and may renew the As-Offered Rate Option as to any
Funding Segment of the As-Offered Rate Portion (I) at any time with respect to
conversion from the Base Rate Option, and (II) at the expiration of any Funding
Period with respect to conversions from or renewals of the As-Offered Rate
Option as to the Funding Segment corresponding to such expiring Funding Period.
Whenever the Borrower desires to convert or renew any interest rate Option with
respect to the Swingline Loans, the Borrower shall provide to the Swingline
Lender notice not later than 1:00 p.m., Pittsburgh time, on the date of such
proposed conversion or renewal, setting forth (w) the date, which shall be a
Business Day, on which the proposed conversion or renewal is to be made, (x) the
principal amount of each Funding Segment of the As-Offered Rate Portion to be
converted from or renewed, (y) the applicable interest rate Option or Options
and the principal amounts of each Funding Segment of the As-Offered Rate Portion
to be converted to, and (z) with respect to each Funding Segment to be converted
to or renewed, the Funding Period therefor. Such notice having been provided,
after the date specified in such notice interest shall be calculated upon the
principal amount of the Swingline Loans as so converted to or renewed. Absent
due notice from the Borrower of conversion or renewal at the expiration of any
Funding Period, any part of the As-Offered Rate Portion for which such notice is
not received shall be converted automatically to the Base Rate Option on the
last day of the expiring Funding Period.

                  (b) LIMITATIONS ON THE MAKING OF SWINGLINE LOANS.

                  (i) SWINGLINE CURRENT AVAILABILITY. The Administrative Agent
shall calculate the Swingline Current Availability each time there is a change
in the aggregate outstanding principal amount of the Revolving Credit Loans, the
aggregate Letter of Credit Exposure, the outstanding principal amount of
Competitive Bid Loans, or the Revolving Credit Committed Amounts. The "Swingline
Current Availability" at any time shall be equal to the lesser of

                  (A) the Swingline Subfacility Amount, or

                  (B) the amount equal to (I) the aggregate Revolving Credit
         Committed Amounts of the Lenders, minus (II) the sum of (x) the
         aggregate principal amount of Revolving Credit Loans, plus (y) the
         aggregate Letter of Credit Exposure, plus (z) the aggregate principal
         amount of Competitive Bid Loans.

Each time the Swingline Current Availability changes, the Administrative Agent
shall promptly notify the Swingline Lender (by telephone promptly confirmed in
writing) of such fact, stating the new Swingline Current Availability. From and
after the second Business Day after receiving such notice from the
Administrative Agent, the Swingline Lender shall not make any Swingline Loan to
the extent that the aggregate principal amount of Swingline Loans would exceed
the Swingline Current Availability so notified to the Swingline Lender.

                  (ii) RIGHTS OF THE PARTIES.

                  (A) As between the Borrower on the one hand, and the Lender
Parties, on the other hand, the making of any Swingline Loan is subject to the
applicable conditions set forth or referred to in this Section 3.02 and Article
V and VIII. In addition, the Swingline Lender shall be justified and fully
protected in declining to make a Swingline Loan if the Swingline Lender has
received notice from the Administrative Agent, acting at the direction of the
Required Lenders, to cease making Swingline Loans as provided in Section
3.02(b)(ii)(B).


                                      -25-
<PAGE>   38

                  (B) As between the Swingline Lender, on the one hand, and the
Administrative Agent and the Lenders, on the other hand, the Swingline Lender
shall not make any Swingline Loan if the Swingline Lender shall have received,
at least two Business Days before making such Swingline Loan, from the
Administrative Agent, acting at the direction of the Required Lenders, an
unrevoked written notice that any applicable condition precedent set forth or
referred to in this Section 3.02 or Article V or VIII will not be satisfied and
expressly requesting that the Swingline Lender cease to make Swingline Loans.
Absent such notice, the Swingline Lender shall be justified and fully protected,
as against the Administrative Agent and the Lenders, in making Swingline Loans,
notwithstanding any knowledge of an Event of Default or Potential Default, any
knowledge of failure of any applicable condition precedent set forth or referred
to in this Section 3.02 or Article V or VIII to be satisfied, any other
knowledge of the Swingline Lender, or any other event, condition or circumstance
whatever.

                  (c) SWINGLINE LOAN PARTICIPATING INTERESTS.

                  (i) GENERALLY. At the discretion of the Swingline Lender at
any time, the Swingline Lender may require each other Lender to purchase,
acquire, accept and assume from the Swingline Lender, without recourse to, or
representation or warranty by, the Swingline Lender, an undivided interest, in a
proportion equal to such Lender's Pro Rata share, in all of the Swingline
Lender's rights in the principal amount of outstanding Swingline Loans, together
with accrued and unpaid interest thereon, and all collateral, guarantees and
other rights from time to time directly or indirectly securing the foregoing
(such interest of each Lender being referred to herein as a "Swingline Loan
Participating Interest"). Amounts other than principal and interest on Swingline
Loans, including amounts payable under or in connection with any zero-balance or
other account maintained with the Swingline Lender or otherwise payable to the
Swingline Lender in connection with any automatic borrowing system or other cash
management operations for the Borrower shall be for the sole account of the
Swingline Lender. On the date that any Purchasing Lender becomes a party to this
Agreement in accordance with Section 10.14, Swingline Loan Participating
Interests in any outstanding Swingline Loans held by the Lender from which such
Purchasing Lender acquired its interest hereunder shall be proportionately
reallocated between such Purchasing Lender and such transferor Lender (and, to
the extent such transferor Lender is a Swingline Lender, the Purchasing Lender
shall be deemed to have acquired a Swingline Loan Participating Interest from
such transferor Lender to such extent).

                  (ii) OBLIGATIONS ABSOLUTE. Notwithstanding any other provision
hereof, each Lender hereby agrees that its obligation to participate in each
Swingline Loan issued in accordance herewith, and its obligation to make the
payments specified in this Section 3.02(c), are each absolute, irrevocable and
unconditional and shall not be affected by any event, condition or circumstance
whatever. The failure of any Lender to make any such payment shall not relieve
any other Lender of its funding obligation hereunder on the date due, but no
Lender shall be responsible for the failure of any other Lender to meet its
funding obligations hereunder.

                  (iii) PAYMENT BY LENDERS ON ACCOUNT OF SWINGLINE LOANS. If the
Swingline Lender desires to sell Swingline Loan Participating Interests to the
Lenders, the Swingline Lender will promptly notify the Administrative Agent
thereof (which notice may be by telephone), and the Administrative Agent shall
forthwith notify each Lender (which notice may be by telephone promptly
confirmed in writing) thereof. No later than the Administrative Agent's close of
business on the date such notice is given by the Administrative Agent (if such
notice is given by the Administrative Agent before 12:00 noon., Pittsburgh time
on such date), each such Lender will pay to the Administrative Agent, for the
account of the Swingline Lender, in immediately available funds, an amount equal
to such Lender's Pro Rata share of the 


                                      -26-
<PAGE>   39

outstanding principal amount of the Swingline Loans and accrued and unpaid
interest thereon. If and to the extent that any Lender fails to make such
payment to the Swingline Lender on such date, such Lender shall pay such amount
on demand, together with interest, for the Swingline Lender's own account, for
each day from and including the date of the Swingline Lender's payment to and
including the date of repayment to the Swingline Lender (before and after
judgment) following rates per annum: (x) for each day from and including the
date of such payment by the Swingline Lender to and including the second
Business Day thereafter, at the Federal Funds Effective Rate for such day, and
(y) for each day thereafter, at the rate applicable to the Swingline Loans for
such day.

                  (iv) DISTRIBUTIONS TO PARTICIPANTS. If, at any time, after the
Swingline Lender has made a Swingline Loan and has received from any Lender such
Lender's share of such Swingline Loan, and the Swingline Lender receives any
payment or makes any application of funds on account of such Swingline Loan, the
Swingline Lender will pay to the Administrative Agent, for the account of such
Lender, such Lender's Pro Rata share of such payment.

                  (v) RESCISSION. If any amount received by the Swingline Lender
on account of any Swingline Loan or interest thereon shall be avoided, rescinded
or otherwise returned or paid over by the Swingline Lender for any reason at any
time, whether before or after the termination of this Agreement (or the
Swingline Lender believes in good faith that such avoidance, rescission, return
or payment is required, whether or not such matter has been adjudicated), each
such Lender will, promptly upon notice from the Administrative Agent or the
Swingline Lender, pay over to the Administrative Agent for the account of the
Swingline Lender its Pro Rata share of such amount, together with its Pro Rata
share of any interest or penalties payable with respect thereto.

                  (vi) EQUALIZATION. If any Lender receives any payment or makes
any application on account of its Swingline Loan Participating Interest, such
Lender shall forthwith pay over to the Swingline Lender, in Dollars and in like
kind of funds received or applied by it the amount in excess of such Lender's
ratable share of the amount so received or applied.

                  (d) CASH MANAGEMENT DOCUMENTATION. The representations,
warranties and covenants by the Borrower under, and rights and remedies of the
Swingline Lender under, any agreements relating to any zero-balance or other
accounts maintained by the Borrower with the Swingline Lender from time to time,
or relating to any automatic borrowing system or other cash management
operations used to make Swingline Loans, are in addition to, and not in
limitation or derogation of, representations, warranties and covenants by the
Borrower under, and rights and remedies of the Swingline Lender and the Lenders
under, this Agreement, the Loan Documents, any other applicable documents,
instruments and agreements, and applicable law. Subject to the foregoing, in the
event of any inconsistency between the terms of this Agreement and any such
agreements or instruments, this Agreement shall prevail. The terms of this
Agreement shall be deemed to be incorporated by reference into each such
agreement or instrument (whether or not such agreement or instrument so states).

                  (e) CERTAIN PROVISIONS RELATING TO THE SWINGLINE LENDER.

                  (i) GENERAL. The Swingline Lender shall have no duties or
responsibilities except those expressly set forth in this Agreement and the
other Loan Documents, and no implied duties or responsibilities on the part of
the Swingline Lender shall be read into this Agreement or any Loan Document or
shall otherwise exist. The duties and responsibilities of the Swingline Lender
to the other Lender Parties under this Agreement and the other Loan Documents
shall be mechanical and administrative in nature, and no Swingline Lender shall
have a fiduciary relationship in respect of any 


                                      -27-
<PAGE>   40

Lender Party or any other Person. The Swingline Lender shall not be liable for
any action taken or omitted to be taken by it under or in connection with this
Agreement or any other Loan Document, unless caused by its own gross negligence
or willful misconduct. The Swingline Lender shall not be under any obligation to
ascertain, inquire or give any notice relating to (i) the performance or
observance of any of the terms or conditions of this Agreement or any other Loan
Document on the part of the Borrower, (ii) the business, operations, condition
(financial or other) or prospects of the Borrower or any other Person, or (iii)
the existence of any Event of Default or Potential Default. The Swingline Lender
shall not be under any obligation, either initially or on a continuing basis, to
provide the Administrative Agent or any Lender with any notices, reports or
information of any nature, whether in its possession presently or hereafter,
except for such notices, reports and other information expressly required by
this Agreement to be so furnished.

                  (ii) ADMINISTRATION. The Swingline Lender may rely upon any
notice or other communication of any nature (written or oral, including but not
limited to telephone conversations, whether or not such notice or other
communication is made in a manner permitted or required by this Agreement or any
Loan Document) purportedly made by or on behalf of the proper party or parties,
and the Swingline Lender shall not have any duty to verify the identity or
authority of any Person giving such notice or other communication. The Swingline
Lender may consult with legal counsel (including, without limitation, in-house
counsel for the Swingline Lender or in-house or other counsel for the Borrower),
independent public accountants and any other experts selected by it from time to
time, and the Swingline Lender shall not be liable for any action taken or
omitted to be taken in good faith in accordance with the advice of such counsel,
accountants or experts. Whenever the Swingline Lender shall deem it necessary or
desirable that a matter be proved or established with respect to the Borrower or
any Lender Party, such matter may be established by a certificate of the
Borrower or such Lender Party, as the case may be, and the Swingline Lender may
conclusively rely upon such certificate.

                  (iii) INDEMNIFICATION OF SWINGLINE LENDER BY LENDERS. Each
Lender hereby agrees to reimburse and indemnify the Swingline Lender and its
directors, officers, employees and agents (to the extent not reimbursed by the
Borrower and without limitation of the obligations of the Borrower to do so),
Pro Rata, from and against any and all amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements of any kind or nature (including, without limitation, the fees and
disbursements of counsel (other than in-house counsel) for the Swingline Lender
or such other Person in connection with any investigative, administrative or
judicial proceeding commenced or threatened, whether or not the Swingline Lender
or such other Person shall be designated a party thereto) that may at any time
be imposed on, incurred by or asserted against the Swingline Lender, in its
capacity as such, or such other Person, as a result of, or arising out of, or in
any way related to or by reason of, this Agreement, any other Loan Document, any
transaction from time to time contemplated hereby or thereby, or any transaction
financed in whole or in part, or directly or indirectly, with the proceeds of
any Swingline Loan, provided, that no Lender shall be liable for any portion of
such amounts, losses, liabilities, claims, damages, expenses, obligations,
penalties, actions, judgments, suits, costs or disbursements resulting from the
gross negligence or willful misconduct of the Swingline Lender or such other
Person.

                  3.03. THE COMPETITIVE BID SUBFACILITY.

                  (a) COMPETITIVE BID LOANS.

                  (i) COMPETITIVE BID LOANS. Subject to the terms and conditions
of this Agreement, the Borrower may, as set forth in this Section 3.03, request
the Lenders from time to time prior to the 


                                      -28-
<PAGE>   41

Revolving Credit Maturity Date to make offers to make Competitive Bid Loans to
the Borrower. Each Lender may, but shall have no obligation to, make one or more
such offers, and the Borrower may, but shall have no obligation to, accept any
such offers, in the manner set forth in this Section 3.03. The Borrower shall
not request or accept any offer to make a Competitive Bid Loan except within the
following limitations: (A) the Investment Grade Rating Condition shall be
satisfied on the date of such request, (B) the aggregate principal amount of
Competitive Bid Loans outstanding at any time shall not exceed $150,000,000, and
(C) the aggregate Revolving Credit Usages of the Lenders may not exceed the
aggregate Revolving Credit Committed Amounts of the Lenders at any time.

                  (ii) MATURITY; INTEREST RATE. The principal amount of each
Competitive Bid Loan shall be due and payable on the last day of the applicable
Funding Period specified in the related Competitive Bid Request, or at such
earlier time as may be required by the Loan Documents. The Borrower may not
voluntarily prepay any Competitive Bid Loan. The outstanding principal amount of
each Competitive Bid Loan shall bear interest for each day until due at a rate
per annum (computed on the basis of a year of 360 days and actual days elapsed)
equal to the Competitive Bid Rate quoted by the Lender making such Competitive
Bid Loan in accordance with Section 3.03(d).

                  (iii) FUNDING PERIODS. The Funding Period for any Competitive
Bid Loan ("Competitive Bid Funding Period") shall be the period commencing on
the date of borrowing specified in the applicable Competitive Bid Request and
ending such number of days thereafter (but not more than 90 days) as the
Borrower may elect; provided, that (A) any Competitive Bid Funding Period which
would otherwise end on a day which is not a Business Day shall be extended to
the next succeeding Business Day, and (B) any Competitive Bid Funding Period
which would otherwise end after the Revolving Credit Maturity Date shall end on
the Revolving Credit Maturity Date.

                  (iv) COMPETITIVE BID NOTES. The obligation of the Borrower to
repay the unpaid principal amount of Competitive Bid Loans made by each Lender
and to pay interest thereon shall be evidenced in part by promissory notes of
the Borrower, dated the date hereof (the "Competitive Bid Notes"), in
substantially the form attached hereto as Exhibit A-3, with the blanks
appropriately filled, payable to the order of such Lender.

                  (v) ADMINISTRATION FEE. The Borrower shall pay to the
Administrative Agent, for its own account, a fee of $500 for each Competitive
Bid Request by the Borrower. Such fee shall be due and payable on demand or, if
no demand is made, on the earliest to occur of (x) the first Regular Payment
Date on or after the date of such Competitive Bid Request or (y) the Revolving
Credit Maturity Date.

                  (b) COMPETITIVE BID REQUESTS. When the Borrower wishes to
request offers to make Competitive Bid Loans under this Section 3.03, it shall
transmit to the Administrative Agent by facsimile transmission or telex a
Competitive Bid Request in substantially the form of Exhibit B-1, duly
completed, so as to be received by the Administrative Agent no later than 11:00
a.m., Pittsburgh time, on the Business Day prior to the date of such Competitive
Bid Borrowing (or such other time and date as the Borrower and the
Administrative Agent shall have mutually agreed and shall have notified to the
Lenders not later than the date of the Competitive Bid Request for the first
proposed Competitive Bid Borrowing for which such change is to become
effective), specifying:

                  (i) The proposed date of such Competitive Bid Borrowing, which
shall be a Business Day;

                  (ii) The principal amount of such proposed Competitive Bid
         Borrowing, which shall be $10,000,000 or a larger multiple of
         $1,000,000; and


                                      -29-
<PAGE>   42

                  (iii) The Funding Period of such proposed Competitive Bid
         Loan, subject to the provisions of Section 3.03(a)(iii).

The Borrower may request offers to make Competitive Bid Loans for more than one
Funding Period in a single Competitive Bid Request. No Competitive Bid Request
shall be given within five Business Days (or such other number of days as the
Borrower and the Administrative Agent may agree) of any other Competitive Bid
Request.

                  (c) COMPETITIVE BID NOTICE OF REQUEST. Promptly upon its
receipt of each Competitive Bid Request, the Administrative Agent shall send to
each Lender by facsimile transmission or telex a notice in substantially the
form of Exhibit B-2 (a "Competitive Bid Notice of Request"), which shall
constitute an invitation by the Borrower to each Lender to submit Competitive
Bid Quotes offering to make the Competitive Bid Loans to which such Competitive
Bid Request relates in accordance with this Section 3.03.

                  (d) SUBMISSION AND CONTENTS OF COMPETITIVE BID QUOTES.

                  (i) SUBMISSION OF COMPETITIVE BID QUOTES. Each Lender may, in
its sole discretion, submit a Competitive Bid Quote containing an offer or
offers to make one or more Competitive Bid Loans in response to a Competitive
Bid Notice of Request. Each Competitive Bid Quote must comply with the
requirements of this Section 3.03(d) and must be submitted to the Administrative
Agent by facsimile transmission or telex at its Office specified in or pursuant
to Section 10.05 so that it is received by the Administrative Agent no later
than 9:30 a.m., Pittsburgh time, on the proposed date of Borrowing (or such
other time or date as the Borrower and the Administrative Agent shall have
mutually agreed and shall have notified to the Lenders not later than the date
of the Competitive Bid Request for the first Competitive Bid Borrowing for which
such change is to be effective); provided, that any Competitive Bid Quote
submitted by the Administrative Agent in the capacity of a Lender may be
submitted, and may only be submitted, if the Administrative Agent notifies the
Borrower of the terms of the offer or offers contained therein not later than 15
minutes prior to the deadline for the other Lenders. Subject to Articles V and
VIII, any Competitive Bid Quote so made shall be irrevocable except with the
written consent of the Administrative Agent given on the instructions of the
Borrower.

                  (ii) CONTENTS OF COMPETITIVE BID QUOTE. Each Competitive Bid
Quote shall be substantially in the form of Exhibit B-3, duly completed, and
shall in any case specify:

                  (A) the proposed date of the Competitive Bid Borrowing and the
Funding Period therefor;

                  (B) the principal amount of the Competitive Bid Loan for which
         each such offer is being made, which principal amount (w) may be
         greater than or less than the Revolving Credit Committed Amount of such
         quoting Lender, (x) must be $5,000,000 or a larger multiple of
         $1,000,000, (y) may not exceed the principal amount of Competitive Bid
         Loans for which offers were requested, and (z) may be subject to an
         aggregate limitation as to the principal amount of Competitive Bid
         Loans for which offers being made by such quoting Lender may be
         accepted;

                  (C) the rate of interest per annum (specified to the nearest
         1/10,000th of 1%) (the "Competitive Bid Rate") offered for each such
         Competitive Bid Loan; and

                  (D) the identity of the quoting Lender.


                                      -30-
<PAGE>   43

A Competitive Bid Quote may set forth up to five separate offers by the quoting
Lender with respect to each Funding Period specified in the related Competitive
Bid Notice of Request.

                  (iii) CERTAIN LIMITATIONS ON COMPETITIVE BID QUOTES. A
Competitive Bid Quote shall be disregarded if it:

                  (A) is not substantially in conformity with Exhibit B-3 or
         does not specify all of the information required by Section
         3.03(d)(ii);

                  (B) contains qualifying, conditional or similar language;

                  (C) proposes terms other than or in addition to those set
         forth in the applicable Competitive Bid Notice of Request; or

                  (D) arrives after the time set forth in Section 3.03(d)(i).

                  (e) NOTICE TO BORROWER. Not later than 10:00 a.m., Pittsburgh
time, on the proposed date of Competitive Bid Borrowing (or such other time as
the Borrower and the Administrative Agent shall have mutually agreed), the
Administrative Agent shall notify the Borrower of the terms (x) of any
Competitive Bid Quote submitted by a Lender that is in accordance with Section
3.03(d) and (y) of any Competitive Bid Quote that amends, modifies or is
otherwise inconsistent with a previous Competitive Bid Quote submitted by such
Lender with respect to the same Competitive Bid Request. Any such subsequent
Competitive Bid Quote shall be disregarded by the Administrative Agent unless
such subsequent Competitive Bid Quote is submitted solely to correct a manifest
error in such former Competitive Bid Quote. The Administrative Agent's notice to
the Borrower shall specify (A) the aggregate principal amount of Competitive Bid
Loans for which offers have been received for each Funding Period specified in
the related Competitive Bid Request, (B) the respective principal amounts and
Competitive Bid Rates, so offered and (C) if applicable, limitations on the
principal amount of Competitive Bid Loans for which offers in any single
Competitive Bid Quote may be accepted.

                  (f) ACCEPTANCE AND NOTICE BY BORROWER. Not later than 10:30
a.m., Pittsburgh time, on the proposed date of Competitive Bid Borrowing (or
such other time and date as the Borrower and the Administrative Agent shall have
mutually agreed and shall have notified to the Lenders not later than the date
of the Competitive Bid Request for the first proposed Competitive Bid Borrowing
for which such change is to be effective), the Borrower shall notify the
Administrative Agent of its acceptance or non-acceptance of the offers so
notified to it pursuant to Section 3.03(e) (and failure by the Borrower to give
such notice by such time shall constitute non-acceptance). In the case of
acceptance, such notice (a "Competitive Bid Acceptance Notice") shall specify
the aggregate principal amount of offers for each Funding Period that are
accepted. The Borrower may, but shall not be obligated to, accept any
Competitive Bid Quote in whole or in part; provided, that:

                  (A) the aggregate principal amount of each Competitive Bid
         Borrowing may not exceed the applicable amount set forth in the related
         Competitive Bid Request;

                  (B) the aggregate principal amount of each Competitive Bid
         Borrowing must be $10,000,000 or a larger multiple of $1,000,000;


                                      -31-
<PAGE>   44

                  (C) acceptance of Competitive Bid Quotes may be made only in
         ascending order of Competitive Bid Rates, beginning with the lowest
         Competitive Bid Rate so offered; and

                  (D) the Borrower may not accept any Competitive Bid Quote that
         is described in Section 3.03(d)(iii) or that otherwise fails to comply
         with the requirements of this Agreement.

                  (g) ALLOCATION BY ADMINISTRATIVE AGENT. If Competitive Bid
Quotes are made by two or more Lenders with the same Competitive Bid Rates for a
greater aggregate principal amount than the amount in respect of which such
Competitive Bid Quotes are accepted for the related Funding Period, the
principal amount of Competitive Bid Loans in respect of which such Competitive
Bid Quotes are accepted shall be allocated by the Administrative Agent among
such Lenders as nearly as possible (in multiples of $1,000,000, as the
Administrative Agent may deem appropriate) in proportion to the aggregate
principal amount of such Competitive Bid Quotes. Determinations by the
Administrative Agent of the amounts of Competitive Bid Loans shall be conclusive
in the absence of manifest error.

                  (h) NOTICE TO THE LENDERS. Upon receipt of a Competitive Bid
Acceptance Notice, the Administrative Agent shall promptly notify each Lender
participating therein of the contents thereof and of such Lenders share (if any)
of such Competitive Bid Borrowing and such Competitive Bid Acceptance Notice
shall not thereafter be revocable by the Borrower.

                  (i) FUNDING OF COMPETITIVE BID LOANS. Unless any applicable
condition specified in Article V hereof has not been satisfied, no later than
2:00 p.m., Pittsburgh time, on the date of each Competitive Bid Borrowing, each
Lender participating therein shall make available its share of such Competitive
Bid Borrowing, in immediately available funds, to the Administrative Agent at
its Office. The Administrative Agent shall make the funds so received available
to the Borrower in funds immediately available at the Administrative Agent's
Office.


                                   ARTICLE IV
                         REPRESENTATIONS AND WARRANTIES

                  The Borrower hereby represents and warrants to each Lender
Party as follows:

                  4.01. CORPORATE STATUS. The Borrower and each Subsidiary of
the Borrower is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation. The Borrower and
each Subsidiary of the Borrower has corporate power and authority to own its
property and to transact the business in which it is engaged or presently
proposes to engage. The Borrower and each Subsidiary of the Borrower is duly
qualified to do business as a foreign corporation and is in good standing in all
jurisdictions in which the ownership of its properties or the nature of its
activities or both makes such qualification necessary or advisable, except for
matters that, individually or in the aggregate, do not have a Material Adverse
Effect.

                  4.02. CORPORATE POWER AND AUTHORIZATION. The Borrower and each
other Loan Party has corporate power and authority to execute, deliver, perform,
and take all actions contemplated by, each Loan Document to which it is a party,
and all such action has been duly and validly authorized by all necessary
corporate proceedings on its part. Without limitation of the foregoing, the
Borrower has the corporate power and authority to borrow and to cause Letters of
Credit to be issued pursuant to the Loan Documents to the fullest extent
permitted hereby and thereby from time to time, and has taken all necessary
corporate action to authorize such borrowings and such issuances of Letters of
Credit.

                  4.03. EXECUTION AND BINDING EFFECT. This Agreement, each other
Loan Document to which the Borrower or any other Loan Party is a party and which
is executed and delivered or required to be executed and delivered on or before
the date as of which this representation and warranty is made, or deemed made,
has been duly and validly executed and delivered by the Borrower or such Loan
Party, as the case may be. This Agreement and each such Loan Document
constitutes, and each other Loan Document when executed and delivered by the
Borrower or such Loan Party, as the case may be, will constitute, the legal,
valid and binding obligation of the Borrower or such Loan Party, as the case may
be, enforceable against the Borrower or such Loan Party, as the case may be, in
accordance with its terms.

                  4.04. GOVERNMENTAL APPROVALS AND FILINGS. No approval, order,
consent, authorization, certificate, license, permit or validation of, or
exemption or other action by, or filing, recording or registration with, or
notice to, any Governmental Authority (collectively, "Governmental Action") is
or will be necessary or reasonably advisable in connection with the execution
and delivery of any Loan Document, consummation of the transactions herein or
therein contemplated (including without limitation the Acquisition), performance
of or compliance with the terms and conditions hereof or thereof or to ensure
the legality, validity, binding effect, enforceability or admissibility in
evidence hereof or thereof, except for (v) such Governmental Actions as have
been obtained or made and are in full force and effect, (w) filings in respect
of Foreign Subsidiaries in connection with the Acquisition which have been duly
made, (x) the filing of an appropriate certificate of merger in connection with
the Merger, (y) filings and recordings in respect of the Liens in favor of the
Collateral Agent securing the Obligations, and (z) filings by the Borrower and
its Subsidiaries pursuant to the Securities Act of 1933, as amended, or the
Securities Exchange Act of 1934, as amended, and rules and regulations
thereunder. Each such Governmental Action has been duly obtained or made, as the
case may be, and is in full force and effect (except for the filing of
continuation statements and like renewal filings and recordings which are not
yet required to be made). There is no action, suit, proceeding or investigation
pending or (to the Borrower's knowledge after due inquiry) threatened which
seeks or may result in the reversal, rescission, termination, modification or
suspension of any such Governmental Action.

                  4.05. ABSENCE OF CONFLICTS. Neither the execution and delivery
of any Loan Document, nor consummation of the transactions herein or therein
contemplated (including without limitation the Acquisition), nor performance of
or compliance with the terms and conditions hereof or thereof, does or will

                  (a) violate or conflict with any Law, or

                  (b) violate or conflict with, or constitute a default under,
         or result in (or give rise to any right, contingent or otherwise, of
         any Person to cause) any termination, cancellation, prepayment or
         acceleration of performance of, or result in the creation or imposition
         of (or give rise to any obligation, contingent or other, to create or
         impose) any Lien upon any property of the Borrower or any Subsidiary of
         the Borrower (except for any Lien in favor of the Collateral Agent
         securing the Obligations) pursuant to, or otherwise result in (or give
         rise to any right, contingent or other, of any Person to cause) any
         change in any right, power, privilege, duty or obligation of the
         Borrower or any Subsidiary of the Borrower under or in connection with,
         (i) the articles of incorporation or by-laws (or other constitutional
         documents) of the Borrower or any Subsidiary of the Borrower, or (ii)
         any agreement or instrument to which the Borrower or any Subsidiary of
         the Borrower is a party or by which any of them or any of their
         respective properties may be subject or bound,


                                      -33-
<PAGE>   46

except, in the case of the foregoing clause (b)(ii), for matters that
individually or in the aggregate, do not have a Material Adverse Effect
(including without limitation the Cross-Default Excepted Indebtedness).

                  4.06. AUDITED FINANCIAL STATEMENTS.

                  (a) BORROWER. The Borrower has furnished to each Lender a copy
of the consolidated balance sheets of the Borrower and its consolidated
Subsidiaries as of June 30, 1997 and June 30, 1996 and the related consolidated
statements of income, cash flows and changes in shareholders' equity for the
fiscal years then ended, as examined and reported on by Arthur Andersen LLP,
independent certified public accountants for the Borrower, as set forth in the
Borrower's reports on Form 10-K for 1997 and 1996. Such financial statements
(including the notes thereto) present fairly, in all material respects, the
financial condition of the Borrower and its consolidated Subsidiaries as of the
end of each such fiscal year and the results of their operations, cash flows and
changes in stockholders' equity for the fiscal years then ended, all in
conformity with GAAP.

                  (b) TARGET. The Borrower has furnished to each Lender a copy
of the consolidated balance sheets of the Target and its consolidated
Subsidiaries as of December 31, 1996 and December 31, 1995 and the related
consolidated statements of income, cash flows and changes in stockholders'
equity for the fiscal years then ended, as examined and reported on by Price
Waterhouse LLP, independent certified public accountants for the Target, as set
forth in the Target's reports on Form 10-K for 1996 and 1995. Such financial
statements (including the notes thereto) present fairly, in all material
respects, the financial condition of the Target and its consolidated
Subsidiaries as of the end of each such fiscal year and the results of their
operations, cash flows and changes in stockholders' equity for the fiscal years
then ended, all in conformity with GAAP.

                  4.07. INTERIM FINANCIAL STATEMENTS.

                  (a) BORROWER. The Borrower has furnished to each Lender a copy
of the interim consolidated balance sheets of the Borrower and its consolidated
Subsidiaries as of the end of the first fiscal quarter of the fiscal year
beginning July 1, 1997 and the related consolidated statements of income and
cash flows for such fiscal quarter, as set forth in the Borrower's report on
Form 10-Q for such fiscal quarter. Such financial statements (including the
notes thereto) present fairly, in all material respects, the financial condition
of the Borrower and its consolidated Subsidiaries as of the end of such fiscal
quarter and the results of their operations and their cash flows for such fiscal
quarter, all in conformity with GAAP, subject to normal and recurring year-end
audit adjustments which are not in the aggregate material, and except that such
financial statements do not contain all of the footnote disclosures required by
GAAP.

                  (b) TARGET. The Borrower has heretofore furnished to each
Lender copies of the interim consolidated balance sheets of Target and its
consolidated Subsidiaries as of the end of the first three fiscal quarters of
the fiscal year beginning January 1, 1997 and the related consolidated
statements of income and cash flows for such fiscal quarters, as set forth in
the Target's reports on Form 10-Q for such fiscal quarters. Such financial
statements (including the notes thereto) present fairly, in all material
respects, the financial condition of Target and its consolidated Subsidiaries as
of the end of each such fiscal quarter and the results of their operations and
their cash flows for each such fiscal quarter, all in conformity with GAAP,
subject to normal and recurring year-end audit adjustments which are not in the
aggregate material, and except that such financial statements do not contain all
of the footnote disclosures required by GAAP.

                  4.08. ABSENCE OF UNDISCLOSED LIABILITIES. Neither the Borrower
nor any Subsidiary of the Borrower has any liability or obligation of any nature
(whether absolute, accrued, contingent or other, 


                                      -34-
<PAGE>   47

whether or not due, including but not limited to forward or long-term
commitments or unrealized or anticipated losses from unfavorable commitments),
except (a) liabilities and obligations disclosed in the financial statements
referred to in Sections 4.06 and 4.07, (b) liabilities and obligations incurred
after June 30, 1997, in the case of the Borrower and its Subsidiaries, or after
December 31, 1996, in the case of Target and its Subsidiaries, in the ordinary
course of business and consistent with past practices, (c) obligations
(including transaction costs) in connection with the Acquisition and this
Agreement, and (d) matters that, individually or in the aggregate, do not have a
Material Adverse Effect.

                  4.09. ACCURATE AND COMPLETE DISCLOSURE. All written
information heretofore, contemporaneously or hereafter provided by or on behalf
of the Borrower or any Subsidiary of the Borrower to any Lender Party pursuant
to or in connection with any Loan Document or any transaction contemplated
hereby or thereby is or will be (as the case may be) true and accurate in all
material respects on the date as of which such information is dated (or, if not
dated, when received by such Lender Party) and does not or will not (as the case
may be) omit to state any material fact necessary to make such information not
misleading at such time in light of the circumstances in which it was provided.
The Borrower has disclosed to the Administrative Agent every occurrence or event
known to the Borrower which has, or which could have so far as the Borrower can
reasonably foresee, a Material Adverse Effect (exclusive of political, social or
economic events of general national or global scope).

                  4.10. SOLVENCY. On the date of each Loan or other extension of
credit under this Agreement and after giving effect to application of the
proceeds thereof in accordance with the terms of the Loan Documents, each Loan
Party and each Significant Subsidiary of the Borrower is and will be Solvent.

                  4.11. MARGIN REGULATIONS. Neither any extension of credit
under this Agreement nor any use of proceeds of any such extension of credit
will violate or conflict with the Margin Regulations. No part of the proceeds of
any extension of credit under this Agreement will be used for the purpose of
buying or carrying Margin Stock or to extend credit to others for the purpose of
buying or carrying any Margin Stock (except proceeds used for the purpose of
buying Target Shares in the Acquisition in accordance with Section 6.09).
Neither the Borrower nor any Subsidiary of the Borrower is engaged in the
business of extending credit to others for the purpose of buying or carrying
Margin Stock. At the time of the making of each Loan and the issuance of each
Letter of Credit after consummation of the Merger, not more than 25% of the
value of the assets of the Borrower and its Subsidiaries taken as a whole will
constitute Margin Stock.

                  4.12. REGULATORY RESTRICTIONS. Neither the Borrower nor any
Subsidiary of the Borrower is (a) an "investment company" or a company
"controlled" by an investment company within the meaning of the Investment
Company Act of 1940, as amended, (b) a "holding company" or a "subsidiary
company" of a "holding company" or an "affiliate" of either a "holding company"
or a "subsidiary company" within the meaning of the Public Utility Holding
Company Act of 1935, as amended, or (c) subject to any other Law which purports
to restrict or regulate its ability to borrow money or obtain credit.

                  4.13. LITIGATION. There is no pending or (to the knowledge of
the Borrower after due inquiry) threatened action, suit, proceeding or
investigation by or before any Governmental Authority against or affecting the
Borrower or any Subsidiary of the Borrower, except for (a) matters set forth in
Schedule 4.13, (b) matters described in the financial statements referred to in
Sections 4.06 and 4.07 and (c) matters that if adversely decided, individually
or in the aggregate, would not reasonably be expected to have a Material Adverse
Effect.


                                      -35-
<PAGE>   48

                  4.14. ABSENCE OF OTHER CONFLICTS. Neither the Borrower nor any
Subsidiary of the Borrower is in violation of or conflict with, or is subject to
any contingent liability on account of any violation of or conflict with:

                  (a) any Law,

                  (b) its articles of incorporation or by-laws (or other
         constitutional documents), or

                  (c) any agreement or instrument to which it is party or by
         which it or any of its properties may be subject or bound,

except for matters that, individually or in the aggregate, would not reasonably
be expected to have a Material Adverse Effect (including without limitation the
Cross-Default Excepted Indebtedness).

                  4.15. INSURANCE. The Borrower and each Subsidiary of the
Borrower maintains with financially sound and reputable insurers (not related to
or affiliated with the Borrower or any Subsidiary of the Borrower) insurance
with respect to its properties and business and against at least such
liabilities, casualties and contingencies and in at least such types and amounts
as is customary in the case of corporations engaged in the same or a similar
business or having similar properties similarly situated.

                  4.16. TITLE TO PROPERTY. The Borrower and each Subsidiary of
the Borrower has good and marketable title to all real property owned or
purported to be owned by it and good title to all other property of whatever
nature owned or purported to be owned by it, in each case necessary or material
to its operations, including but not limited to the property reflected in the
most recent audited balance sheets referred to in Section 4.06 or submitted
pursuant to Section 6.01(a), as the case may be (except as sold or otherwise
disposed of after the date of such balance sheets in transactions which, before
the effective date of this Agreement, were permitted by the applicable
agreements referred to in Section 5.01(m), and after the effective date of this
Agreement, are permitted by the Loan Documents), in each case free and clear of
all Liens, other than Permitted Liens.

                  4.17. INTELLECTUAL PROPERTY. The Borrower and each Subsidiary
of the Borrower owns, or is licensed or otherwise has the right to use, all the
patents, trademarks, service marks, names (trade, service, fictitious or other),
copyrights, technology (including but not limited to computer programs and
software), know-how, processes, databases and other rights, free from burdensome
restrictions, necessary to own and operate its properties and to carry on its
business as presently conducted and presently planned to be conducted without
conflict with the rights of others, except for matters that, individually or in
the aggregate, do not have a Material Adverse Effect.

                  4.18. TAXES. All tax and information returns required to be
filed by or on behalf of the Borrower or any Subsidiary of the Borrower have
been properly and timely prepared, executed and filed, except for matters that,
individually or in the aggregate, do not have a Material Adverse Effect. All
taxes, assessments, fees and other governmental charges upon the Borrower or any
Subsidiary of the Borrower or upon any of their respective properties, incomes,
sales or franchises which are due and payable have been paid, other than those
not yet delinquent and payable without premium or penalty, except for matters
that, individually or in the aggregate, do not have a Material Adverse Effect.
The reserves and provisions for taxes on the books of the Borrower and each
Subsidiary of the Borrower for all open years and for its current fiscal period
are adequate in accordance with GAAP. Neither the Borrower nor any Subsidiary of
the Borrower knows of any proposed additional assessment or basis for any
assessment for additional taxes 


                                      -36-
<PAGE>   49

(whether or not reserved against), except for matters that, individually or in
the aggregate, do not have a Material Adverse Effect.

                  4.19. EMPLOYEE BENEFITS. Each Plan and, to the knowledge of
the Borrower, each Multiemployer Plan, is in compliance in all material respects
with, and has been administered in all material respects in compliance with, its
terms and the applicable provisions of ERISA, the Code, and each other
applicable state, federal and foreign law. No Pension-Related Event has occurred
and is continuing. Neither the Borrower nor any Controlled Group Member has
incurred any liability to the PBGC, other than liabilities for payment of
periodic PBGC payments

                  4.20. ENVIRONMENTAL MATTERS. In the ordinary course of its
business, the Borrower reviews the effect of applicable Environmental Laws on
the business, operations and properties of the Borrower and its Subsidiaries, in
the course of which it identifies and evaluates actual and potential associated
liabilities and costs (including without limitation any capital or operating
expenditures required for clean-up or closure of properties presently or
previously owned or operated, any capital or operating expenditures required to
achieve or maintain compliance with environmental protection standards imposed
by Law or as a condition of any license, permit or contract, any related
constraints on operating activities, including any periodic or permanent
shutdown of any facility, restriction on transportation of any substance or
reduction in the level of or change in the nature of operations and any actual
or potential liabilities to third parties, including employees, and any related
costs and expenses). On the basis of its review, the Borrower has reasonably
concluded that Environmental Laws do not have a Material Adverse Effect.

                  (e) REPRESENTATIONS AND WARRANTIES. Each of the
         representations and warranties made by each Loan Party herein and in
         each other Loan Document shall be true and correct in all material
         respects on and as of such date as if made on and as of such date, both

                  (g) NO VIOLATIONS OF LAW. Neither the making nor use of the

         June 30, 1997, or of Target and its Subsidiaries taken as a whole since
         December 31, 1996, except as reflected in the financial statements
         furnished pursuant to Section 4.06 and 4.07.

                  (i) LITIGATION. Without limiting the generality of Sections
         4.13 and 5.01(e), there shall not be pending or (to the knowledge of

         proceeding or investigation by or before any Governmental Authority
         which (i) seeks to challenge, prevent or declare illegal any
         transaction contemplated by the Loan Documents (including without
         limitation the purchase of Target Shares pursuant to the Offer to
         Purchase, or the Merger), (ii) could have a material adverse effect on
         the business, operations, condition (financial or other) or prospects
         of the Borrower and its Subsidiaries (including Target and its
         Subsidiaries) taken as a whole.

                  (j) OFFICERS' CERTIFICATES. The Administrative Agent shall
         have received a certificate dated the Closing Date, signed by a
         Responsible Officer of the Borrower, in the form attached hereto as
         Exhibit E and as to such other matters as the Administrative Agent may
         request.

                  (k) PROJECTIONS. The Borrower shall have prepared and
         delivered to the Administrative Agent the following items (the "Closing
         Date Projections"): a table of sources and uses of funds associated
         with the Acquisition, pro forma financial statements as of September
         30, 1997 reflecting the Acquisition (including the incurrence and
         payment of Indebtedness in connection with the Acquisition), and other
         acquisitions made by the Borrower since September 30, 1997 (including
         the incurrence and payment of indebtedness in connection therewith),
         and projections covering the periods through the Revolving Credit
         Maturity Date, accompanied by a written statement of the assumptions
         and estimates underlying such projections. The Closing Date Projections
         shall be in form satisfactory to the Administrative Agent and each
         Syndication Agent and shall in any case be at least as detailed as the
         similar items delivered by the Borrower to the Administrative Agent and
         each Syndication Agent under cover of a letter dated October 13, 1997
         (the "Commitment Date Projections"). The Closing Date Projections shall
         not show a financial condition, results of operations or cash flows for
         any date or period materially less favorable (in the good faith
         judgment of the Administrative Agent or any Syndication Agent) than
         shown in the Commitment Date Projections. As of the Closing Date, (i)
         the Closing Date Projections (including 


                                      -39-
<PAGE>   52


         the assumptions and estimates on which the Closing Date Projections are
         based) shall be reasonable, shall represent the Borrower's best
         judgment on such matters, and shall be consistent with the requirements
         of the Loan Documents, (ii) there shall be no statements or conclusions
         in the Closing Date Projections which are based upon or include
         information known to the Borrower to be materially misleading or which
         fail to take into account material information regarding the matters
         reported therein, and (iii) nothing shall have come to the attention of
         the Borrower as of the Closing Date which would lead it to believe that
         the Closing Date Projections will not be attained or exceeded.

                  (l) LEGAL OPINIONS. The Administrative Agent shall have
         received the following opinion, addressed to the Administrative Agent,
         the Collateral Agent and each Lender and dated the Closing Date:

         interest, fees and other amounts outstanding or otherwise payable in
         connection with the following agreements or instruments, all
         commitments to lend under or in connection therewith shall have been
         terminated, all outstanding letters of credit under or in connection
         therewith (if any) shall have been terminated, and all collateral
         security (if any) therefor shall have been released: (i) Credit
         Agreement dated as of April 19, 1996 among the Borrower, and Deutsche
         Bank AG, New York Branch and/or Cayman Islands Branch, Mellon Bank,
         N.A., and PNC Bank, National Association, as lenders, as amended, and
         (ii) Credit Facilities and Reimbursement Agreement dated as of December
         9, 1996 by and among the Target and two other named borrowers,
         NationsBank, N.A. and five other named lenders, and NationsBank, N.A.,

                  (n) ACQUISITION DOCUMENTS. The Borrower shall have provided to
         the Administrative Agent a true, correct and complete copy, certified
         as such by the Borrower, of (i) the Merger Agreement (including all
         exhibits, schedules and disclosure letters, if any, delivered pursuant
         thereto, all amendments and waivers relating thereto, and any side
         letters or agreements affecting the terms thereof), and (ii) the Offer
         to Purchase and all amendments, exhibits and related documents filed
         with the Securities and Exchange Commission or distributed to the
         stockholders of Target in connection with the Offer to Purchase. The
         Merger Agreement as initially executed shall not have been amended,
         modified or supplemented, nor shall any condition thereof shall have
         been waived, except as consented to in writing by the Administrative
         Agent.

                  (o) ACQUISITION CONDITIONS. On the Closing Date all conditions
         to the purchase of Target Shares pursuant to the Merger Agreement set
         forth in the Merger Agreement shall have been satisfied, without
         amendment, modification, supplement or waiver of any condition by the
         parties thereto, except as consented to in writing by the
         Administrative Agent.

                  (p) ACQUISITION REPRESENTATIONS. The representations and
         warranties of the Borrower, Merger Sub and Target contained in or made
         pursuant to the Merger Agreement shall be true and correct in all
         material respects as of the dates as of which such representations and
         warranties are made under or pursuant to the Merger Agreement and

         only as of another date) as of the Closing Date.

                  (q) PURCHASE OF TARGET SHARES; ABSENCE OF IMPEDIMENTS. Not
         later than December 30, 1997, Merger Sub shall have accepted for
         purchase and consummated the purchase of all validly tendered Target
         Shares pursuant to the Merger Agreement and the Offer to Purchase
         (which shall be an amount sufficient to satisfy the "Minimum Condition"
         referred to in the Merger Agreement), subject only to payment therefor,
         at a price not to exceed $38 per Target Share. Under the Delaware
         General Corporation Law, the Merger may be consummated with only the
         affirmative vote of the shares owned by Merger Sub. There shall be no
         applicable state shareholder protection, anti-takeover or other
         legislation which would delay, or prevent, the consummation of the
         Merger. All material governmental and third party approvals (including
         without limitation the expiration of all waiting periods under the
         Hart-Scott-Rodino Antitrust Improvements Act of 1976) necessary in
         connection with the Acquisition shall have been obtained and be in full
         force and effect, and all applicable waiting periods shall have expired
         without any action being taken by any Governmental Authority which has
         restrained, prevented, or otherwise imposed materially adverse
         conditions on the Acquisition. The Administrative Agent shall have
         received copies, certified by the Secretary or an Assistant Secretary
         of the Borrower, of all filings made with any governmental authority
         which the Administrative Agent shall have requested. There shall be no
         other material impediment to the consummation of the Acquisition in
         accordance with the Merger Agreement.

                  (r) OFFER TO PURCHASE. The Offer to Purchase and any
         amendments or supplements thereto and, at the time of filing thereof,
         all documents required to be filed with the Securities and Exchange
         Commission by the Borrower, Merger Sub or Target pursuant to the
         Securities Act of 1933, as amended or the Securities Exchange Act of
         1934, as amended, shall not contain any untrue statement of a material
         fact or omit to state any material fact necessary in order to make
         statements therein, in the light of the circumstances under which they
         were made, not misleading.

                  (s) FEES, EXPENSES, ETC. All fees and other compensation
         required to be paid to the Administrative Agent or the Lenders pursuant
         hereto or any other agreement on or prior to the Closing Date shall
         have been paid or received.

                  (t) ADDITIONAL MATTERS. All corporate and other proceedings,
         and all documents, instruments and other matters in connection with the
         transactions contemplated by the Loan Documents, shall be satisfactory
         in form and substance to the Administrative Agent. The Administrative
         Agent shall have received such other documents, instruments and other
         items as the Administrative Agent may reasonably request.

                  5.02. CONDITIONS TO EXTENSION OF CREDIT AFTER THE CLOSING
DATE. The obligation of each Lender to make any Loan (other than on the Closing
Date) and the obligation of the Issuing Bank Representative to cause Issuing
Banks to issue any Letters of Credit (other than on the Closing Date) is subject
to performance by each of the Loan Parties of their respective obligations to be
performed under the Loan Documents on or before the date such Loan is made or
such Letter of Credit is issued, to satisfaction of any conditions precedent set
forth elsewhere in the Loan Documents and to satisfaction of the following
further conditions precedent:

                  (a) BASIC CONDITIONS. (i) In the case of a Revolving Credit
         Loan, Letter of Credit, Swingline Loan, or Competitive Bid Loan,
         immediately after giving effect thereto, the aggregate Revolving Credit
         Usages will not exceed the aggregate Revolving Credit Committed
         Amounts, (ii) in the case of a Letter of Credit, issuance of such
         Letter of Credit is consistent with Sections 3.01(a)(i) and
         3.01(a)(ii), (iii) in the case of a Swingline Loan, the making of such
         Swingline Loan 


                                      -41-
<PAGE>   54

         is consistent with Section 3.02(a)(i), and (iv) in the case of a
         Competitive Bid Loan, the request for and making of such Competitive
         Bid Loan is consistent with Section 3.03(a)(i).

                  (b) NOTICE. Notice with respect to such Loan or Letter of
         Credit shall have been given by the Borrower in accordance with Article
         II or Article III, as the case may be.

                  (c) REPRESENTATIONS AND WARRANTIES. Each of the
         representations and warranties made by each Loan Party herein and in
         each other Loan Document shall be true and correct in all material
         respects on and as of such date as if made on and as of such date, both
         before and after giving effect to the Loans requested to be made and
         Letters of Credit requested to be issued on such date (except for
         Sections 4.06 and 4.07, which are made only as of the date of this
         Agreement).

                  (d) NO DEFAULT. No Event of Default or Potential Default shall
         have occurred and be continuing on such date or after giving effect to
         the Loans requested to be made (including any deemed request) or the
         Letters of Credit requested to be issued (including any deemed request)
         on such date.

                  (e) NO VIOLATIONS OF LAW. Neither the making nor use of the
         Loans or the Letters of Credit shall cause any Lender Party to violate
         any Law.

                  (f) NO MATERIAL ADVERSE CHANGE. There shall not have occurred
         a material adverse change in the business, operations, condition
         (financial or other) or prospects of the Borrower and its Subsidiaries
         taken as a whole (including Target and its Subsidiaries) since June 30,
         1997, except as reflected in the financial statements furnished
         pursuant to Sections 4.06 and 4.07.

Each request (including any deemed request) by the Borrower for any Loan or
Letter of Credit shall constitute a representation and warranty by the Borrower
that the conditions set forth in this Section 5.03 have been satisfied as of the
date of such request. Failure of the Administrative Agent to receive notice from
the Borrower to the contrary before such Loan is made or Letter of Credit is
issued shall constitute a further representation and warranty by the Borrower
that the conditions referred to in this Section 5.03 have been satisfied as of
the date such Loan is made or such Letter of Credit is issued.

                  5.03. ADDITIONAL CONDITIONS TO EXTENSION OF CREDIT ON THE
MERGER DATE.. The obligation of each Lender to make any Loan on the Merger Date
and the willingness of each Issuing Bank to issue any Letter of Credit and of
the Swingline Lender to make any Swingline Loans on the Merger Date is subject
to satisfaction of the conditions precedent set forth or referred to in Section
5.02 and to satisfaction of the following further conditions precedent:

                  (a) MERGER. The conditions to the Merger set forth in the
         Merger Agreement shall have been satisfied (without giving effect to
         any amendment, modification or waiver except as consented to in writing
         by the Administrative Agent). A certificate of merger consistent with
         the Merger Agreement shall have been filed with the Delaware Secretary
         of State in accordance with the Delaware General Corporation Law. The
         Merger shall have been consummated and shall have become effective in
         accordance with the terms of the Merger Agreement and such certificate
         of merger. The Borrower shall own beneficially and of record and have
         good title to all of the outstanding capital stock of the Target, as
         surviving corporation in the Merger, free and clear of any Lien, except
         for Liens in favor of the Collateral Agent securing the Obligations,
         and such capital stock shall be duly authorized and validly issued and
         are fully paid and nonassessable. There shall be no options, warrants,
         calls, subscriptions, conversion rights, exchange rights, 


                                      -42-

         preemptive rights or other rights, agreements or arrangements
         (contingent or other) which may in any circumstances now or hereafter
         obligate Target or any Subsidiary of the Target to issue any shares of
         its capital stock.

                  (b) SECURITY DOCUMENTS. The Collateral Agent shall have
         received the following, each of which shall be in form and substance

         Agreement and, as of the Merger Date, satisfies the criteria set forth
         in Section 6.13(b) for pledging additional capital stock or other

                              AFFIRMATIVE COVENANTS

                  The Borrower hereby covenants to each Lender Party as follows:

                  6.01. BASIC REPORTING REQUIREMENTS.

                  (a) ANNUAL AUDIT REPORTS. As soon as practicable, and in any
event within 120 days after the close of each fiscal year of the Borrower, the
Borrower shall furnish to the Administrative Agent, with a copy for each Lender,
consolidated statements of income, cash flows and changes in stockholders'
equity of the Borrower and its consolidated Subsidiaries for such fiscal year
and a consolidated balance sheet for the Borrower and its consolidated
Subsidiaries as of the close of such year, and notes to each, all in reasonable
detail, prepared on a comparative basis in accordance with GAAP. Such financial
statements 

                                      -44-
<PAGE>   57

shall be accompanied by an opinion of Arthur Andersen LLP or other independent
certified public accountants of recognized national standing selected by the
Borrower and reasonably satisfactory to the Administrative Agent. Such opinion
shall be free of any exception, qualification or explanation not reasonably
acceptable to the Administrative Agent (and in any event shall be free of any
exception, qualification or explanation relating to ability to continue as a
going concern, a limited scope of examination or independence). Such opinion in
any event shall contain a written statement of such accountants substantially to
the effect that (x) such accountants audited such consolidated financial
statements in accordance with generally accepted auditing standards and (y) in
the opinion of such accountants such audited financial statements present
fairly, in all material respects, the financial position of the Borrower and its
consolidated Subsidiaries as of the end of such fiscal year and the results of
their operations and their cash flows and changes in stockholders' equity for
such fiscal year, in conformity with GAAP.

                  (b) QUARTERLY REPORTS. As soon as practicable, and in any
event within 60 days after the close of each of the first three fiscal quarters
of each fiscal year of the Borrower, the Borrower shall furnish to the
Administrative Agent, with a copy for each Lender, consolidated statements of
income, cash flows and stockholders' equity of the Borrower and its consolidated
Subsidiaries for such fiscal quarter and for the period from the beginning of
such fiscal year to the end of such fiscal quarter, and consolidated balance
sheet of the Borrower and its consolidated Subsidiaries as of the close of such
fiscal quarter, and notes to each, all in reasonable detail, setting forth in
comparative form the corresponding figures for the same periods or as of the
same date during the preceding fiscal year (except for the consolidated balance
sheet, which shall set forth in comparative form the corresponding balance sheet
as of the prior fiscal year end). Such financial statements shall be certified
by a Responsible Officer of the Borrower as presenting fairly, in all material
respects, the financial position of the Borrower and its consolidated
Subsidiaries as of the end of such fiscal quarter and the consolidated results
of their operations and their cash flows and changes in stockholders' equity for
such fiscal quarter, in conformity with GAAP, subject to normal and recurring
year-end audit adjustments.

                  (c) COMPLIANCE CERTIFICATES. Concurrently with the delivery of
the financial statements referred to in Sections 6.01(a) and 6.01(b), the
Borrower shall deliver, or cause to be delivered, to the Administrative Agent,
with a copy for each Lender, a Compliance Certificate in substantially the form
set forth as Exhibit D, duly completed and signed by a Responsible Officer of
the Borrower.

                  (d) CERTAIN OTHER REPORTS AND INFORMATION. Promptly upon the

         matters which, if adversely decided, individually or in the aggregate,
         would not have a Material Adverse Effect;

                  (iv) Any material violation, breach or default by the Borrower
         or any Subsidiary of the Borrower of or under any agreement or
         instrument material to the business, operations, condition (financial
         or other) or prospects of the Borrower and its Subsidiaries taken as a
         whole;

                  (v) Any Pension-Related Event, other than (w) any Reportable

         applicable regulations, and (x) any Pension-Related Event described in
         subsection (d) or (f) of the definition thereof which involves a
         liability of the Borrower, any Subsidiary of the Borrower or any

         of becoming an actual liability) of less than $1,000,000 in the
         aggregate for all such Persons. Such notice shall be accompanied by the
         following: (A) a copy of any notice, request, return, petition or other

         the Internal Revenue Service, the Department of Labor, the PBGC or any
         Plan participant, beneficiary, alternate payee or employer
         representative), in connection with such Pension-Related Event, and (B)
         in the case of any Pension-Related Event with respect to a Plan, the

         under any facility or property now or previously owned, operated or
         leased by any Loan Party or any Subsidiary of any Loan Party or any of
         their respective Environmental Affiliates) that could form the basis of
         such Environmental Claim, which Environmental Claim, if adversely
         resolved, individually or in the aggregate, would be likely to have a
         Material Adverse Effect.

                  (g) VISITATION; VERIFICATION. The Borrower shall permit such
Persons as the Administrative Agent or any Lender may designate from time to
time to visit and inspect any of the properties of the Borrower and any
Subsidiary of the Borrower, to examine their respective books and records and

their respective directors, officers, employees and independent accountants, all
upon reasonable notice to the Borrower, at 


                                      -46-
<PAGE>   59

such reasonable times (it being understood that, so long as no Event of Default
or Potential Default has occurred and is continuing, such times shall be during
normal business hours) and as often as may reasonably be requested by the
Administrative Agent or any Lender. The Borrower hereby authorizes such
officers, employees and independent accountants to discuss with the
Administrative Agent or any Lender the affairs of the Borrower and its
Subsidiaries.

                  6.02. INSURANCE. The Borrower shall, and shall cause each of
its Subsidiaries to, maintain with financially sound and reputable insurers
insurance with respect to its properties and business and against such
liabilities, casualties and contingencies and of such types as is customary in
the case of Persons engaged in the same or a similar business or having similar
properties similarly situated.

                  6.03. PAYMENT OF TAXES AND OTHER POTENTIAL CHARGES AND
PRIORITY CLAIMS. The Borrower shall, and shall cause each of its Subsidiaries
to, pay and discharge, or cause to be paid and discharged,

                  (a) on or prior to the date on which penalties attach thereto,
         all taxes, assessments and other governmental charges imposed upon it,
         or any of them, or any of its, or any of their, properties;

                  (b) on or prior to the date when due, all lawful claims of
         materialmen, mechanics, carriers, warehousemen, landlords and other
         like Persons which, if unpaid, might result in the creation of a Lien
         upon any such property; and

                  (c) on or prior to the date when due, all other lawful claims
         which, if unpaid, might result in the creation of a Lien upon any such
         property or which, if unpaid, might give rise to a claim entitled to
         priority over general creditors of the Borrower or such Subsidiary in a
         case under Title 11 (Bankruptcy) of the United States Code, as amended,
         or under foreign bankruptcy, insolvency or similar Laws;

provided, that, unless and until foreclosure, distraint, levy, sale or similar
proceedings shall have been commenced, the Borrower or such Subsidiary need not
pay or discharge, or cause the payment or discharge, of any such tax,
assessment, charge or claim above so long as (x) such reserves or other
appropriate provisions as may be required by GAAP shall have been made therefor,
and (y) such failure to pay or discharge would not have a Material Adverse
Effect.

                  6.04. PRESERVATION OF CORPORATE STATUS. The Borrower shall,
and shall cause each of its Subsidiaries to, maintain its status as a
corporation duly organized, validly existing and, to the extent applicable, in
good standing under the laws of its jurisdiction of organization; provided, that
(i) so long as no Event of Default or Potential Default then exists or would be
created thereby, the Borrower may terminate the corporate existence or permit to
lapse the good standing or existence of any of its Subsidiaries (other than a
Loan Party) if, in the good faith judgment of the appropriate officers of the
Borrower, such termination would not be disadvantageous to the Borrower or the
Lender Parties in any material respect and (ii) the Borrower and its
Subsidiaries which are Loan Parties may enter into transactions permitted by
Section 7.06. The Borrower shall, and shall cause each of its Subsidiaries to,
at all times be duly qualified to do business as a foreign corporation and, to
the extent applicable, in good standing in all jurisdictions in which the
ownership of its properties or the nature of its business or both make such
qualification necessary or advisable, except for matters that, individually or
in the aggregate, do not, and would not be reasonably likely to, have a Material
Adverse Effect.


                                      -47-
<PAGE>   60


                  6.05. GOVERNMENTAL APPROVALS AND FILINGS. The Borrower shall,
and shall cause each of its Subsidiaries to, keep and maintain in full force and
effect all Governmental Actions necessary or reasonably advisable in connection
with execution and delivery of any Loan Document, consummation of the
transactions herein or therein contemplated, performance of or compliance with
the terms and conditions hereof or thereof, or to ensure the legality, validity,
binding effect, enforceability or admissibility in evidence hereof or thereof.

                  6.06. MAINTENANCE OF PROPERTIES, FRANCHISES, ETC. The Borrower
shall, and shall cause each of its Subsidiaries to, (a) maintain or cause to be
maintained in good repair, working order and condition the properties now or
hereafter owned, leased or otherwise possessed by it and shall make or cause to
be made all needful and proper repairs, renewals, replacements and improvements
thereto so that the business carried on in connection therewith may be properly
and advantageously conducted at all times, except where failure to do so does
not, and would not be reasonably likely to, have a Material Adverse Effect, and
(b) maintain and hold in full force and effect all franchises, licenses,
permits, certificates, authorizations, qualification, accreditations and other
rights, consents and approvals (whether issued, made or given by a Governmental
Authority or otherwise), necessary to own and operate its properties and to
carry on its business as presently conducted and as presently planned to be
conducted, except where failure to do so does not, and would not be reasonably
likely to, have a Material Adverse Effect.

                  6.07. AVOIDANCE OF OTHER CONFLICTS. The Borrower shall not,
and shall not permit any of its Subsidiaries to, violate or conflict with, be in
violation of or conflict with, or be or remain subject to any liability
(contingent or other) on account of any violation or conflict with

                  (a) any Law,

                  (b) its articles of incorporation or by-laws (or other
         constitutional documents), or

                  (c) any agreement or instrument to which it or any of its
         Subsidiaries is a party or by which any of them or any of their
         respective properties may be subject or bound,

except for matters that, individually or in the aggregate, do not, and would not
be reasonably likely to, have a Material Adverse Effect.

                  6.08. FINANCIAL ACCOUNTING PRACTICES. The Borrower shall, and
shall cause each of its Subsidiaries to, make and keep books, records and
accounts which, in reasonable detail, accurately and fairly reflect its
transactions and dispositions of its assets, and maintain a system of internal
accounting controls sufficient to provide reasonable assurances that (a)
transactions are executed in accordance with management's general or specific
authorization, (b) transactions are recorded as necessary (i) to permit
preparation of financial statements in conformity with GAAP and (ii) to maintain
accountability for assets, (c) access to assets is permitted only in accordance
with management's general or specific authorization and (d) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

                  6.09. USE OF PROCEEDS. The Borrower shall apply the proceeds
of the Loans under this Agreement as follows: (a) up to $1,250,000,000 in the
aggregate may be used on the Closing Date and the Merger Date (i) to fund the
Acquisition and to pay transaction costs associated therewith, (ii) to refinance
indebtedness of Kennametal, Target and their respective Subsidiaries, and (iii)
to pay fees and expenses associated with this Agreement (and, in the case of the
Term Loans, to repay Revolving Credit Loans that 


                                      -48-
<PAGE>   61

were used for the foregoing purposes), and (b) for working capital, capital
expenditures and general corporate purposes of the Borrower from time to time on
and after the Closing Date. The Borrower shall not use any Letters of Credit or
the proceeds of any Loans directly or indirectly for any unlawful purpose, in
any manner inconsistent with or that would violate or conflict with the Margin
Regulations, in any manner inconsistent with Section 4.11, or in any manner
inconsistent with any other provision of the Loan Documents.

                  6.10. CONTINUATION OF OR CHANGE IN BUSINESS. The Borrower
shall not, and shall not permit any of its Subsidiaries to, engage in any
business if, as a result, the general nature of the business, on a consolidated
basis, which would then be engaged in by the Borrower and its Subsidiaries would
be substantially and significantly changed from the general nature of the
business engaged in by the Borrower and its Subsidiaries (including Target and
its Subsidiaries) on a consolidated basis on the Closing Date, or such business
is not reasonably related to the business of the Borrower and its Subsidiaries
(including Target and its Subsidiaries) on a consolidated basis on the Closing
Date. The Borrower shall continue to operate as an operating company in
substantially the manner as at the date hereof, and shall not transfer to any
Subsidiary, in any transaction or set of related transactions, any material
portion of the Borrower's operating assets.

                  6.11. PLANS AND MULTIEMPLOYER PLANS.

                  (a) REQUIRED CONTRIBUTIONS. The Borrower shall, and shall
cause each Subsidiary of the Borrower and Controlled Group Members to, make
contributions to each Plan when due in accordance with the minimum funding
requirements under ERISA and the Code applicable to such Plan and pay any
required PBGC premiums as and when due for such Plan.

                  (b) REQUIRED CONTRIBUTIONS TO MULTIEMPLOYER PLANS. The
Borrower shall, and shall cause each Subsidiary of the Borrower and Controlled
Group Members to, make contributions required to be made by it, or any of them,
to each Multiemployer Plan, if any, when due in accordance with its, or any of
their, obligations under any collective bargaining agreement related to such
Multiemployer Plan or participation agreements applicable to such Multiemployer
Plan, except those contributions the requirement of which are reasonably being
contested by a Controlled Group Member provided that failure to make such
contested contributions is not a violation of applicable Law and does not
present a material risk of resulting in liability (contingent or other) to the
Borrower or any Subsidiary of the Borrower.

                  (c) FUNDING. The Borrower shall, and shall cause each of its
Subsidiaries to, make any required contributions to any arrangements for
providing retirement and/or death benefits when due, in accordance with the
terms of the arrangement and any minimum funding requirements which are
applicable to the arrangement from time to time.

                  6.12. INTEREST RATE PROTECTION.

                  (a) REQUIRED HEDGE. The Borrower shall, promptly (and in any
event not later than 90 days) after the date the Term Loans are made, enter into
one or more Interest Rate Hedging Agreements on such terms as shall be
reasonably satisfactory to the Administrative Agent and which (when taken
together with the Borrower's obligations under the Term Loan) have the economic
effect of fixing the Borrower's effective interest cost on at least 50% of the
scheduled outstanding principal amount of Term Loans for the period through and
including the thirteenth Quarterly Amortization Date. The Borrower shall
thereafter select interest rate Options with respect to the Term Loans that
match, in time and amount, as closely as may be the terms of the rate hedge
represented by such Interest Rate Hedging Agreements.


                                      -49-
<PAGE>   62

                  (b) SECURING THE REQUIRED HEDGE. If the Borrower so requests,
the Administrative Agent shall consent to Swap Party Supplements to the
Collateral Agency Agreement (as defined therein) whereby the Interest Rate
Hedging Agreements referred to in Section 6.12(a) shall be deemed a Swap
Agreement entitled to the benefits of the Collateral Agency Agreement, provided,
that in each case the counterparty to such Interest Rate Hedging Agreement is a
Lender and the terms and conditions of such Interest Rate Hedging Agreement are
reasonably satisfactory to the Administrative Agent. The Administrative Agent
may consent to Swap Party Supplements relating to Interest Rate Hedging
Agreements if the conditions set forth in this Section 6.12(b) are satisfied,
even if such Interest Rate Hedging Agreements in the aggregate exceed in amount
or time the minimum requirements set forth in Section 6.12(a).

                  (c) ADVANCE ENTRY INTO THE REQUIRED HEDGE. To the extent
otherwise consistent with this Agreement and the other Loan Documents, the
Borrower may enter into Interest Rate Hedging Agreements in advance of the date
on which it is required to do so under Section 6.12(a). In the event that the
Borrower subsequently is required to enter into Interest Rate Hedging Agreements
under Section 6.12(a) any then-existing Interest Rate Hedging Agreements to
which Borrower is party and which otherwise satisfy the requirements of Section
6.12(a) may be counted toward satisfaction of the Borrower's obligations under
Section 6.12(a), and to the extent that such Interest Rate Hedging Agreements
satisfy the requirements of Section 6.12(b) the Administrative Agent may consent
to a Swap Party Supplement to the Collateral Agency Agreement with respect to
such Interest Rate Hedging Agreements.

                  6.13. SUBSIDIARY GUARANTORS; PLEDGE OF SUBSIDIARY STOCK;
RELEASE OF PLEDGE.

                  (a) ADDITIONAL SUBSIDIARY GUARANTORS. The Borrower will cause
each Person which is or becomes a Significant Subsidiary (other than (x) a
Subsidiary which is not organized under the laws of the United States or a state
or political subdivision jurisdiction thereof, (y) Distribution and its
Subsidiaries, and (z) before the Merger Date, Target and its Subsidiaries) to
become a Subsidiary Guarantor as promptly as practicable after (but in any event
within 90 days of) the date such Person first satisfies the foregoing criteria,
by causing such Subsidiary to execute and deliver to the Collateral Agent a
supplement to the Subsidiary Guaranty, together with (i) an opinion of counsel
for such Subsidiary (which counsel may be an employee of the Borrower or such
Subsidiary) in substantially the form attached to the Subsidiary Guaranty and
covering such other matters relating to such Subsidiary Guaranty as the
Administrative Agent may reasonably request, and (ii) all documents which the
Administrative Agent may reasonably request relating to the existence of such
Subsidiary, the corporate authority for and the validity of such Subsidiary
Guaranty, and any other matters reasonably determined by the Administrative
Agent to be relevant thereto, all in form and substance reasonably satisfactory
to the Administrative Agent.

                  (b) SUBSIDIARY STOCK PLEDGE. Subject to Section 6.13(c), in
the event that the Borrower or any Subsidiary Guarantor at any time owns,
beneficially or of record, capital stock or other equity interests in a
Significant Subsidiary (other than (x) before the Merger Date, Target and its
Subsidiaries, (y) before December 25, 1997, Distribution, and (z) before the
termination of the covenant referred to in Section 6.13(d), Hanita), the
Borrower shall as promptly as practicable after (but in any event within 90 days
of) the date the Borrower or such Subsidiary Guarantor first satisfies the
foregoing criteria, (i) execute and deliver to the Collateral Agent a supplement
to the Borrower Pledge Agreement (in the case of the Borrower) or Subsidiary
Pledge Agreement (in the case of a Subsidiary Guarantor; provided, if such
Subsidiary Guarantor is not party to a Subsidiary Pledge Agreement the Borrower
also will cause such Subsidiary Guarantor to execute and deliver a Subsidiary
Pledge Agreement), designating such Significant Subsidiary to be a "Designated
Subsidiary" thereunder, (ii) deliver to the Collateral Agent the certificates
and instruments representing the stock certificates and other instruments
relating to such Designated 


                                      -50-
<PAGE>   63

Subsidiary which are required to be delivered pursuant to such Borrower Pledge
Agreement or such Subsidiary Pledge Agreement, as the case may be, accompanied
by undated duly executed instruments of transfer or assignment in blank, in form
and substance satisfactory to the Administrative Agent, (iii) do such other acts
and things as may be necessary or, in the opinion of the Administrative Agent,
desirable to create, perfect or protect the Liens created or purported to be
created by the Borrower Pledge Agreement or such Subsidiary Pledge Agreement, as
the case may be, and (iv) without limiting the generality of the foregoing
clause (iii), to the extent, if any, that such Designated Subsidiary is foreign,
such additional or supplementary security documentation, satisfactory in form
and substance to the Administrative Agent, as may be necessary or, in the
opinion of the Administrative Agent, desirable to create, perfect or protect the
Liens created or purported to be created by the above Shared Security Documents,
and such opinions of foreign counsel, reasonably satisfactory in form and
substance to the Administrative Agent, as to such matters as the Administrative
Agent may reasonably request.

                  (c) RELEASE OF PLEDGED STOCK. If on any day after the Closing
Date (i) the Borrower either (A) satisfies the Investment Grade Rating
Condition, or (B) the Consolidated Leverage Ratio is less than 3.0 as of the end
of each of the two consecutive fiscal quarters of the Borrower ending after the
Closing Date most recently ended before such day, (ii) no Event of Default or
Potential Default has occurred and is continuing or exists, and (iii) a
Responsible Officer of the Borrower has submitted a certification to the
foregoing effect to the Administrative Agent, accompanied by a request that the
Liens granted to the Collateral Agent on the Shared Collateral under the
Borrower Pledge Agreement and the Subsidiary Pledge Agreement, then (x) the
Administrative Agent will instruct the Collateral Agent to execute and deliver
to the Borrower such documents as the Borrower may reasonably request to effect
such release, and (y) the Borrower shall have no further obligations under
Section 6.13(b).

                  (d) HANITA. The Borrower will use its commercially reasonable
best efforts to procure the termination (by waiver, or by payment of the related
Indebtedness) of any covenant made by Target in connection with Indebtedness of
Hanita outstanding on the Closing Date which would prohibit the pledge by Target
to the Collateral Agent of the capital stock of Hanita owned by Target.

                  6.14. CONSUMMATION OF THE ACQUISITION. The Borrower will use
its commercially reasonable best efforts to cause the Merger Date to occur at
the earliest practicable time.


                                   ARTICLE VII
                               NEGATIVE COVENANTS

                  The Borrower hereby covenants to each Lender Party as follows:

                  (a) CONSOLIDATED NET WORTH. On the Closing Date, and as of the
end of each fiscal quarter of the Borrower ending after the Closing Date,
Consolidated Net Worth shall not be less than the amount equal to the sum of (i)
$475,000,000, plus (ii) an amount equal to 50% of Consolidated Net Income for
each fiscal quarter of the Borrower commencing after September 30, 1997 and
ending on or prior to the date of determination, in each case for which
Consolidated Net Income is positive (it being understood that there shall be no
deduction on account of negative Consolidated Net Income for any fiscal quarter
of the Borrower), plus (iii) 100% of the aggregate increase in Consolidated Net
Worth on account of issuance (including without limitation any issuance in
connection with the conversion or exchange of 


                                      -51-
<PAGE>   64

any Indebtedness or other obligations) after September 30, 1997 of any capital
stock of the Borrower or any of its Subsidiaries.

                  (b) CONSOLIDATED LEVERAGE RATIO. On the Closing Date, and as

         have been modified or amended or shall have been held to be illegal or
         invalid, and such event or condition has or could reasonably be

each Lender Party hereby irrevocably authorizes the Administrative Agent to
execute and deliver the Collateral Agency Agreement on behalf of such Lender
Party. Each Lender Party hereby agrees that the rights and remedies granted to
the Administrative Agent under the Loan Documents shall be exercised exclusively
by the Administrative Agent, and that no Lender Party shall have any right
individually to exercise any such right or remedy, except to the extent, if any,
expressly provided herein or therein.

                  9.02. GENERAL NATURE OF ADMINISTRATIVE AGENT'S DUTIES.

                  (a) NO IMPLIED DUTIES. The Administrative Agent shall have no
duties or responsibilities except those expressly set forth in this Agreement
and the other Loan Documents, and no implied duties or responsibilities on the
part of the Administrative Agent shall be read into this Agreement or any Loan
Document or shall otherwise exist.

                  (b) NOT A FIDUCIARY. The duties and responsibilities of the
Administrative Agent under this Agreement and the other Loan Documents shall be
mechanical and administrative in nature, and the Administrative Agent shall not
have a fiduciary relationship in respect of any Lender Party.

                  (c) ADMINISTRATIVE AGENT OF LENDER PARTIES. The Administrative
Agent is and shall be solely the Administrative Agent of the Lender Parties. The
Administrative Agent does not assume, and shall not at any time be deemed to
have, any relationship of agency or trust with or for, or any other duty or
responsibility to, the Borrower or any Person other than the Lender Parties. The
provisions of this Article IX are for the benefit of the Lender Parties (and the
other Persons named in Section 9.07), and the Borrower shall not have any rights
under any of the provisions of this Article IX.

                  (d) NO OBLIGATION TO TAKE ACTION. The Administrative Agent
shall be under no obligation to take any action hereunder or under any other
Loan Document if the Administrative Agent believes in good faith that taking
such action may conflict with any Law or any provision of this Agreement or any
other Loan Document, or may require the Administrative Agent to qualify to do
business in any jurisdiction where it is not then so qualified.

                  9.03. EXERCISE OF POWERS. Subject to the other provisions of
this Agreement and the other Loan Documents, the Administrative Agent shall take
any action of the type specified in this Agreement or any other Loan Document as
being within the Administrative Agent's rights, powers or discretion in
accordance with directions from the Required Lenders (or, to the extent this
Agreement or such Loan Document expressly requires the direction or consent of
some other Person or set of Persons, then instead in accordance with the
directions of such other Person or set of Persons). In the absence of such
directions, the Administrative Agent shall have the authority (but under no
circumstances shall be obligated), in its sole discretion, to take any such
action, except to the extent this Agreement or such Loan Document expressly
requires the direction or consent of the Required Lenders (or some other Person
or set of Persons), in which case the Administrative Agent shall not take such
action absent such direction or consent. Any action or inaction pursuant to such
direction, discretion or consent shall be binding on all the Lender Parties. The
Administrative Agent shall not have any liability to any Person as a result of
(x) the Administrative Agent acting or refraining from acting in accordance with
the directions of the Required Lenders (or other applicable Person or set of
Persons), (y) the Administrative Agent refraining from acting in the absence of
instructions to act from the Required Lenders (or other applicable Person or set
of Persons), whether or not the Administrative Agent has discretionary power to
take such action, or (z) the Administrative Agent taking discretionary action it
is authorized to take under this Section (subject, in the case of this clause
(z), to the provisions of Section 9.04(a)).

                  9.04. GENERAL EXCULPATORY PROVISIONS.

                  (a) GENERAL. The Administrative Agent shall not be liable for
any action taken or omitted to be taken by it under or in connection with this
Agreement or any other Loan Document, unless caused by its own gross negligence
or willful misconduct.


                                      -64-
<PAGE>   77

                  (b) ADMINISTRATIVE AGENT NOT RESPONSIBLE FOR LOAN DOCUMENTS,
ETC. The Administrative Agent shall not be responsible for (i) the execution,
delivery, effectiveness, enforceability, genuineness, validity or adequacy of
this Agreement or any other Loan Document, (ii) any recital, representation,
warranty, document, certificate, report or statement in, provided for in, or
received under or in connection with, this Agreement or any other Loan Document,
(iii) any failure of the Borrower, any Lender or Issuing Bank to perform any of
their respective obligations under this Agreement or any other Loan Document,
(iv) the existence, validity, enforceability, perfection, recordation, priority,
adequacy or value, now or hereafter, of any Lien or other direct or indirect
security afforded or purported to be afforded by any of the Loan Documents or
otherwise from time to time, or (v) caring for, protecting, insuring, or paying
any taxes, charges or assessments with respect to any collateral.

                  (c) NO DUTY OF INQUIRY. The Administrative Agent shall not be
under any obligation to ascertain, inquire or give any notice relating to (i)
the performance or observance of any of the terms or conditions of this
Agreement or any other Loan Document on the part of the Borrower, (ii) the
business, operations, condition (financial or other) or prospects of the
Borrower or any other Person, or (iii) except to the extent set forth in Section
9.05(f), the existence of any Event of Default or Potential Default.

                  (d) NOTICES. The Administrative Agent shall not be under any
obligation, either initially or on a continuing basis, to provide any Lender
Party with any notices, reports or information of any nature, whether in its
possession presently or hereafter, except for such notices, reports and other
information expressly required by this Agreement or any other Loan Document to
be furnished by the Administrative Agent to such Lender Party.

                  9.05.  ADMINISTRATION BY THE ADMINISTRATIVE AGENT.

                  (a) RELIANCE ON NOTICES. The Administrative Agent may rely
upon any notice or other communication of any nature (written or oral, including
but not limited to telephone conversations, whether or not such notice or other
communication is made in a manner permitted or required by this Agreement or any
Loan Document) purportedly made by or on behalf of the proper party or parties,
and the Administrative Agent shall not have any duty to verify the identity or
authority of any Person giving such notice or other communication.

                  (b) CONSULTATION. The Administrative Agent may consult with
legal counsel (including, without limitation, in-house counsel for the
Administrative Agent or in-house or other counsel for the Borrower), independent
public accountants and any other experts selected by it from time to time, and
the Administrative Agent shall not be liable for any action taken or omitted to
be taken in good faith by it in accordance with the advice of such counsel,
accountants or experts.

                  (c) RELIANCE ON CERTIFICATES, ETC. The Administrative Agent
may conclusively rely upon the truth of the statements and the correctness of
the opinions expressed in any certificates or opinions furnished to the
Administrative Agent in accordance with the requirements of this Agreement or
any other Loan Document. Whenever the Administrative Agent shall deem it
necessary or desirable that a matter be proved or established with respect to
the Borrower or any Lender Party, such matter may be established by a
certificate of the Borrower or such Lender Party, as the case may be, and the
Administrative Agent may conclusively rely upon such certificate (unless other
evidence with respect to such matter is specifically prescribed in this
Agreement or another Loan Document).

                  (d) INDEMNITY. The Administrative Agent may fail or refuse to
take any action unless it shall be indemnified to its satisfaction from time to
time against any and all amounts, liabilities, 


                                      -65-
<PAGE>   78

obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind or nature which may be imposed on,
incurred by or asserted against the Administrative Agent by reason of taking or
continuing to take any such action.

                  (e) PERFORMANCE THROUGH ADMINISTRATIVE AGENTS. The
Administrative Agent may perform any of its duties under this Agreement or any
other Loan Document by or through agents or attorneys-in-fact. The
Administrative Agent shall not be responsible for the negligence or misconduct
of any agents or attorneys-in fact selected by it with reasonable care.

                  (f) NOTICE OF DEFAULT. The Administrative Agent shall not be
deemed to have any knowledge or notice of the occurrence of any Event of Default
or Potential Default unless the Administrative Agent has received notice from a
Lender Party or the Borrower referring to this Agreement, describing such Event
of Default or Potential Default, and stating that such notice is a "notice of
default." If the Administrative Agent receives such a notice, the Administrative
Agent shall give prompt notice thereof to each Lender.

                  9.06. LENDERS NOT RELYING ON ADMINISTRATIVE AGENT OR OTHER
LENDERS. Each Lender Party hereby acknowledges as follows: (a) Neither the
Administrative Agent nor any other Lender Party has made any representations or
warranties to it, and no act taken hereafter by the Administrative Agent or any
other Lender Party shall be deemed to constitute any representation or warranty
by the Administrative Agent or such other Lender Party to it. (b) It has,
independently and without reliance upon the Administrative Agent or any other
Lender Party, and based upon such documents and information as it has deemed
appropriate, made its own credit and legal analysis and decision to enter into
this Agreement and the other Loan Documents. (c) It will, independently and
without reliance upon the Administrative Agent or any other Lender Party, and
based upon such documents and information as it shall deem appropriate at the
time, make its own decisions to take or not take action under or in connection
with this Agreement and the other Loan Documents.

                  9.07. INDEMNIFICATION OF ADMINISTRATIVE AGENT BY LENDERS. Each
Lender hereby agrees to reimburse and indemnify the Administrative Agent and its
directors, officers, employees and agents (to the extent not reimbursed by the
Borrower and without limitation of the obligations of the Borrower to do so),
Pro Rata, from and against any and all amounts, losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements of any kind or nature (including, without limitation, the fees and
disbursements of counsel for the Administrative Agent or such other Person in
connection with any investigative, administrative or judicial proceeding
commenced or threatened, whether or not the Administrative Agent or such other
Person shall be designated a party thereto) that may at any time be imposed on,
incurred by or asserted against the Administrative Agent or such other Person as
a result of, or arising out of, or in any way related to or by reason of, this
Agreement, any other Loan Document, any transaction from time to time
contemplated hereby or thereby, or any transaction financed in whole or in part
or directly or indirectly with the proceeds of any Loan or Letter of Credit;
provided, that no Lender shall be liable for any portion of such amounts,
losses, liabilities, claims, damages, expenses, obligations, penalties, actions,
judgments, suits, costs or disbursements resulting from the gross negligence or
willful misconduct of the Administrative Agent or such other Person.

                  9.08. ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY. With
respect to its Commitments and the Loan Obligations owing to it, the
Administrative Agent shall have the same rights and powers under this Agreement
and each other Loan Document as any other Lender and may exercise the same as
though it were not the Administrative Agent, and the terms "Lender," "Swingline
Lender," "Issuing Bank," "holders of Notes" and like terms shall include the
Administrative Agent in its individual 


                                      -66-
<PAGE>   79

capacity as such. The Administrative Agent and its affiliates may, without
liability to account, make loans to, accept deposits from, acquire debt or
equity interests in, enter into derivatives transactions with, act as trustee
under indentures of, and engage in any other business or transaction with, the
Borrower or any stockholder, subsidiary or affiliate of the Borrower, as though
the Administrative Agent were not the Administrative Agent hereunder.

                  9.09. HOLDERS OF NOTES. The Administrative Agent may deem and
treat the Lender which is payee of a Note as the owner and holder of such Note
for all purposes hereof unless and until a Transfer Supplement with respect to
the assignment or transfer thereof shall have been filed with the Administrative
Agent in accordance with Section 10.14. Any authority, direction or consent of
any Person who at the time of giving such authority, direction or consent is
shown in the Register as being a Lender shall be conclusive and binding on each
present and subsequent holder, transferee or assignee of any Note or Notes
payable to such Lender or of any Note or Notes issued in exchange therefor.

                  9.10. SUCCESSOR ADMINISTRATIVE AGENT. The Administrative Agent
may resign at any time by giving 45 days' prior written notice thereof to the
Lenders and the Borrower. The Administrative Agent may be removed by the
Required Lenders at any time by giving 10 days' prior written notice thereof to
the Administrative Agent, the other Lenders and the Borrower. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint a
successor Administrative Agent (subject to the Borrower's consent, which will
not be unreasonably withheld or delayed). If no successor Administrative Agent
shall have been so appointed and consented to, and shall have accepted such
appointment, within 30 days after such notice of resignation or removal, then
the retiring Administrative Agent may (but shall not be required to) appoint a
successor Administrative Agent. Each successor Administrative Agent shall be a
commercial bank or trust company organized under the laws of the United States
of America or any State thereof and having a combined capital and surplus of at
least $500,000,000. Upon the acceptance by a successor Administrative Agent of
its appointment as Administrative Agent hereunder, such successor Administrative
Agent shall thereupon succeed to and become vested with all the properties,
rights, powers, privileges and duties of the former Administrative Agent in its
capacity as such, without further act, deed or conveyance. Upon the effective
date of resignation or removal of a retiring Administrative Agent, such
Administrative Agent shall be discharged from its duties as such under this
Agreement and the other Loan Documents, but the provisions of this Agreement
shall inure to its benefit as to any actions taken or omitted by it while it was
Administrative Agent under this Agreement. If and so long as no successor
Administrative Agent shall have been appointed, then any notice or other
communication required or permitted to be given by the Administrative Agent
shall be sufficiently given if given by the Required Lenders, all notices or
other communications required or permitted to be given to the Administrative
Agent shall be given to each Lender, and all payments to be made to the
Administrative Agent shall be made directly to the Borrower or Lender Party for
whose account such payment is made.

                  9.11. CALCULATIONS. The Administrative Agent shall not be
liable for any calculation, apportionment or distribution of payments made by it
in good faith. If such calculation, apportionment or distribution is
subsequently determined to have been made in error, the sole recourse of any
Lender Party to whom payment was due but not made shall be to recover from the
other Lender Parties any payment in excess of the amount to which they are
determined to be entitled or, if the amount due was not paid by the Borrower, to
recover such amount from the Borrower.

                  9.12. ADMINISTRATIVE AGENT'S FEE. The Borrower agrees to pay
to the Administrative Agent, for its individual account, such fees as are set
forth in a separate letter agreement between the Administrative Agent and the
Borrower.


                                      -67-
<PAGE>   80

                  9.13. FUNDING BY ADMINISTRATIVE AGENT. Unless the
Administrative Agent shall have been notified in writing by any Lender not later
than the close of business on the day before the day on which a Loan is
requested by the Borrower to be made that such Lender will not make such Loan,
the Administrative Agent may assume that such Lender will make such Loan, and in
reliance upon such assumption the Administrative Agent may (but in no
circumstances shall be required to) make available to the Borrower a
corresponding amount. If and to the extent that any Lender fails to make such
payment to the Administrative Agent on such date, such Lender shall pay such
amount on demand (or, if such Lender fails to pay such amount on demand, the
Borrower shall pay such amount on demand), together with interest, for the
Administrative Agent's own account, for each day from and including the date of
the Administrative Agent's payment to and including the date of repayment to the
Administrative Agent (before and after judgment) at the following rates per
annum: (x) for each day from and including the date of such payment by the
Administrative Agent to and including the second Business Day thereafter, at the
Federal Funds Effective Rate for such day, and (y) for each day thereafter, at
the rate applicable to such Loans for such day. If a Lender shall repay to the
Administrative Agent the amount made available by the Administrative Agent to
the Borrower, such amount so repaid shall thereafter constitute a Loan by such
Lender for purposes of this Agreement. All payments to the Administrative Agent
under this Section shall be made to the Administrative Agent at its Office in
Dollars in funds immediately available at such Office, without set-off,
withholding, counterclaim or other deduction of any nature.

                  9.14. SYNDICATION AGENTS. The title "Syndication Agent," given
to certain Lenders named on the cover page of this Agreement, is purely
honorific, and no Syndication Agent, as in its capacity as such, shall have any
duties or responsibilities.


                                    ARTICLE X
                                  MISCELLANEOUS

                  10.01. HOLIDAYS. Except as otherwise expressly provided herein
or therein, whenever any payment or action to be made or taken hereunder or
under any other Loan Document shall be stated to be due on a day which is not a
Business Day, such payment or action shall be made or taken on the next
following Business Day and such extension of time shall be included in computing
interest or fees, if any, in connection with such payment or action.

                  10.02. RECORDS. The unpaid principal amount of the Committed
Loans and the Competitive Bid Loans owing to each Lender, the unpaid interest
accrued thereon, the interest rate or rates applicable to such unpaid principal
amount, the duration of such applicability, each Lender's Revolving Credit
Committed Amount and Term Loan Committed Amount and the accrued and unpaid fees
owing to each Lender Party shall at all times be ascertained from the records of
the Administrative Agent, which shall be conclusive absent manifest error. The
unpaid Letter of Credit Reimbursement Obligations, the unpaid interest accrued
thereon, and the interest rate or rates applicable thereto shall at all times be
ascertained from the records of the Issuing Bank, which shall be conclusive
absent manifest error. The unpaid principal amount of the Swingline Loans, the
unpaid interest accrued thereon and the interest rate or rates applicable
thereto shall at all times be ascertained from the records of the Swingline
Lender, which shall be conclusive absent manifest error.

                  10.03. AMENDMENTS AND WAIVERS. The Administrative Agent and
the Borrower may from time to time amend, modify or supplement the provisions of
this Agreement or any other Loan Document (other than the Shared Security
Documents) for the purpose of amending, adding to, or waiving any provisions,
releasing any collateral, or changing in any manner the rights and duties of the
Borrower or 


                                      -68-
<PAGE>   81

any Lender Party. Any such amendment, modification or supplement made by the
Borrower and the Administrative Agent in accordance with the provisions of this
Section 10.03 shall be binding upon the Borrower and each Lender Party. The
Administrative Agent shall enter into such amendments, modifications or
supplements from time to time as directed by the Required Lenders, and only as
so directed, provided, that no such amendment, modification or supplement may be
made which will:

                  (a) Increase the Revolving Credit Committed Amount or Term
         Loan Committed Amount of any Lender over the amount thereof then in
         effect without the written consent of each Lender affected thereby, or
         extend the Revolving Credit Maturity Date without the written consent
         of each Lender;

                  (b) Reduce the principal amount of or extend the time for any
         scheduled payment of principal of any Loan without the written consent
         of each Lender affected thereby, or reduce the rate of interest or
         extend the time for payment of interest borne by any Loan or Letter of
         Credit Reimbursement Obligation (other than as a result of waiving the
         applicability of any increase in interest rates applicable to overdue
         amounts), or extend the time for payment of or reduce the amount of any
         Revolving Credit Commitment Fee or Letter of Credit Fee, without the
         written consent of each Lender affected thereby;

                  (c) Change the definition of "Required Lenders" or amend this
         Section 10.03, without the written consent of each Lender;

                  (d) Amend or waive any of the provisions of Article IX, or
         impose additional duties upon the Administrative Agent, or otherwise
         affect the rights, interests or obligations of the Administrative
         Agent, without the written consent of the Administrative Agent; amend
         or waive any of the provisions of Section 3.01, or impose additional
         duties upon any Issuing Bank, or otherwise affect the rights, interests
         or obligations of any Issuing Bank, without the written consent of the
         Issuing Bank Representative; or amend or waive any of the provisions of
         Section 3.02, or impose additional duties upon the Swingline Lender, or
         otherwise affect the rights, interests or obligations of the Swingline
         Lender, without the written consent of the Swingline Lender;

                  (e) Alter the priority of distributions set forth in Section
         8.03, without the written consent of each Lender affected thereby;

                  (f) Reduce any Letter of Credit Unreimbursed Draw, or extend
         the time for repayment by the Borrower of any Letter of Credit
         Unreimbursed Draw, without the written consent of each Lender; or

                  (g) Release all or substantially all of the Shared Collateral
         (other than in accordance with the provisions of the Loan Documents),
         or terminate the Subsidiary Guaranty, without the written consent of
         Supermajority Lenders;

and provided further, that Transfer Supplements may be entered into in the
manner provided in Section 10.14. Any such amendment, modification or supplement
must be in writing, manually signed by or on behalf of the Borrower and the
Lender Party which is party thereto, and shall be effective only to the extent
set forth in such writing. Any Event of Default or Potential Default waived or
consented to in any such amendment, modification or supplement shall be deemed
to be cured and not continuing to the extent and for the period set forth in
such waiver or consent, but no such waiver or consent shall extend to any 


                                      -69-
<PAGE>   82

other or subsequent Event of Default or Potential Default or impair any right
consequent thereto. Shared Security Documents may be amended, modified and
supplemented from time to time in accordance with the terms thereof and of the
Collateral Agency Agreement, and any such amendment, modification or supplement
so made shall be binding upon the Borrower and each Lender Party (and to the
extent that any consent, direction or other action is required by the
Administrative Agent in connection therewith, the provisions of the third
sentence of this Section 10.03 shall apply to the Administrative Agent in giving
such consent or direction or taking such action as if such action were an
amendment, modification or supplement of this Agreement).

                  10.04. NO IMPLIED WAIVER; CUMULATIVE REMEDIES. No course of
dealing and no delay or failure of the Collateral Agent or any Lender Party in
exercising any right, power or privilege under this Agreement or any other Loan
Document shall affect any other or future exercise thereof or exercise of any
other right, power or privilege; nor shall any single or partial exercise of any
such right, power or privilege or any abandonment or discontinuance of steps to
enforce such a right, power or privilege preclude any further exercise thereof
or of any other right, power or privilege. The rights and remedies of the
Collateral Agent and the Lender Parties under this Agreement and any other Loan
Document are cumulative and not exclusive of any rights or remedies which any of
them would otherwise have hereunder or thereunder, at law, in equity or
otherwise.

                  10.05. NOTICES.

                  (a) GENERAL. Except to the extent otherwise expressly
permitted hereunder or thereunder, all notices, requests, demands, directions
and other communications (collectively "notices") to the Borrower or any Lender
Party under this Agreement or any Loan Document shall be in writing (including
telexes and facsimile transmission) and shall be sent by first-class mail, or by
nationally-recognized overnight courier, or by telex or facsimile transmission
(with confirmation in writing mailed first-class or sent by such an overnight
courier), or by personal delivery. All notices shall be sent to the applicable
party (x) in the case of the Borrower or the Administrative Agent, at the
address stated on the signature pages hereof, (y) in the case of any Lender, at
its address set forth in its Administrative Questionnaire, or (z) in the case of
any party, in at such address as it may specify for the purpose by notice to the
Administrative Agent and the Borrower. Any such properly given notice shall be
effective when received.

                  (b) COPIES TO ADMINISTRATIVE AGENT. Any Lender giving any
notice to the Borrower or any other party to a Loan Document shall
simultaneously send a copy thereof to the Administrative Agent.

                  (c) RELIANCE. Each Lender Party may rely on any notice
(whether or not such notice is made in a manner permitted or required by this
Agreement or any Loan Document) purportedly made by or on behalf of the
Borrower, and no Lender Party shall have any duty to verify the identity or
authority of any Person giving such notice.

                  10.06. EXPENSES; INDEMNITY.

                  (a) EXPENSES. The Borrower agrees to pay or cause to be paid
and to save each Lender Party harmless against liability for the payment of all
reasonable out-of-pocket costs and expenses (including but not limited to
reasonable fees and expenses of outside counsel, including local counsel,
auditors, and all other professional, accounting, evaluation and consulting
costs) from time to time arising from or relating to (i) in the case of the
Administrative Agent and each Syndication Agent, the negotiation, preparation,
execution, delivery and syndication of this Agreement and the other Loan
Documents (it being 


                                      -70-
<PAGE>   83

understood that this clause (i) shall not entitle any Syndication Agent to be
reimbursed for legal expenses, except to the extent, if any, such Syndication
Agent engaged local counsel at the request of the Administrative Agent), (ii) in
the case of the Administrative Agent, administration and performance of this
Agreement and the other Loan Documents, and any requested amendments,
modifications, supplements, waivers or consents (whether or not ultimately
entered into or granted) to this Agreement or any Loan Document, and (iii) in
the case of each Lender Party, the enforcement or preservation of rights under
this Agreement or any Loan Document (including but not limited to any such costs
or expenses arising from or relating to (A) the creation, perfection or
protection of any Lien on any collateral, (B) the protection, collection, lease,
sale, taking possession of, preservation of, or realization on, any collateral,
including without limitation advances for taxes, filing fees and the like, (C)
collection or enforcement by any Lender Party of any outstanding Loan or any
other amount owing hereunder or thereunder, and (D) any litigation, proceeding,
dispute, work-out, restructuring or rescheduling related in any way to this
Agreement or the Loan Documents, it being understood, however, that this clause
(iii) shall not entitle a Lender to reimbursement of expenses incurred by such
Lender in exercising rights under Section 6.01(g) unless an Event of Default or
Potential Default has occurred and is continuing).

                  (b) INDEMNITY. The Borrower hereby agrees to reimburse and
indemnify the Lender Parties, their respective affiliates, and the directors,
officers, employees, attorneys and agents of each of the foregoing (the "Lender
Indemnified Parties"), and each of them, and to hold each of them harmless from
and against, any and all losses, liabilities, claims, damages, expenses,
obligations, penalties, actions, judgments, suits, costs or disbursements of any
kind or nature whatsoever (including, without limitation, the fees and
disbursements of outside counsel for such Lender Indemnified Party in connection
with any investigative, administrative or judicial proceeding commenced or
threatened, whether or not such Lender Indemnified Party shall be designated a
party thereto) that may at any time be imposed on, asserted against or incurred
by such Lender Indemnified Party as a result of, or arising out of, or in any
way related to or by reason of this Agreement or any other Loan Document, any
transaction from time to time contemplated hereby or thereby, or any transaction
financed or secured in whole or in part, directly or indirectly, with the
proceeds of any Loan or by any Letter of Credit or the proceeds thereof (and
without in any way limiting the generality of the foregoing, including any grant
of any Lien on collateral or any exercise by the Collateral Agent or any Lender
Party of any of its rights or remedies under this Agreement or any other Loan
Document); but excluding any portion of such losses, liabilities, claims,
damages, expenses, obligations, penalties, actions, judgments, suits, costs or
disbursements resulting from the gross negligence or willful misconduct of such
Lender Indemnified Party. If and to the extent that the foregoing obligations of
the Borrower under this Section 10.06(b), or any other indemnification
obligation of the Borrower hereunder or under any other Loan Document, are
unenforceable for any reason, the Borrower hereby agrees to make the maximum
contribution to the payment and satisfaction of such obligations which is
permissible under applicable Law.

                  10.07. SEVERABILITY. The provisions of this Agreement are
intended to be severable. If any provision of this Agreement shall be held
invalid or unenforceable in whole or in part in any jurisdiction such provision
shall, as to such jurisdiction, be ineffective to the extent of such invalidity
or unenforceability without in any manner affecting the validity or
enforceability thereof in any other jurisdiction or the remaining provisions
hereof in any jurisdiction.

                  10.08. PRIOR UNDERSTANDINGS. This Agreement and the other Loan
Documents supersede all prior and contemporaneous understandings and agreements,
whether written or oral, among the parties hereto and thereto relating to the
transactions provided for herein and therein, including the commitment letter
dated October 14, 1997; provided, however, that (x) the Borrower's obligations
to make the payments contemplated by the origination fee letter referred to in
such commitment letter shall survive 


                                      -71-
<PAGE>   84

execution of this Agreement, and (y) the Borrower, the initial Lenders and the
Administrative Agent have entered into a letter agreement, dated as of the date
hereof, captioned "Special Funding Procedures" (the "Special Funding Procedures
Letter"), which relates to special notice procedures and interest rate
provisions for certain Loans to be made on or shortly after the Closing Date,
and the Special Funding Procedures Letter supplements and forms part of this
Agreement.

                  10.09. EFFECTIVENESS; DURATION; SURVIVAL.

                  (a) EFFECTIVENESS. This Agreement shall become effective on
the date that the Administrative Agent shall have received counterparts hereof
signed by each of the parties hereto (or, in the case of any party as to which
an executed counterparty shall not have been received, receipt by the
Administrative Agent of facsimile or other written confirmation from such party
of execution of a counterpart hereof by such party.

                  (b) DURATION; SURVIVAL. All covenants and agreements of the
Borrower contained in this Agreement shall continue in full force and effect
from and after the date this Agreement becomes effective until all Commitments
have terminated, all Letters of Credit have expired or have been terminated, and
all Loan Obligations (other than Contingent Indemnification Obligations) have
been indefeasibly paid in full in cash. Without limitation, all obligations of
the Borrower hereunder or under any other Loan Document to make payments to or
indemnify any Lender Party or Lender Indemnified Party (including but not
limited to obligations arising under Sections 2.10, 2.11 and 10.06) shall
survive the payment in full of all other Loan Obligations, termination of the
Borrower's right to borrow hereunder, and all other events and conditions
whatever. In addition, all obligations of each Lender to make payments to or
indemnify the Administrative Agent, the Swingline Lender or the Issuing Banks
and Persons related to the Administrative Agent, the Swingline Lender or the
Issuing Banks (including but not limited to obligations arising under Sections
3.01(h)(iii), 3.02(e)(iii) and 9.07) shall survive the payment in full by the
Borrower of all Loan Obligations, termination of the Borrower's right to borrow
hereunder, and all other events and conditions whatever. All representations and
warranties of the Borrower contained herein or in any other Loan Document or
made in connection herewith or therewith shall survive the making of, and shall
not be waived by the execution and delivery, of this Agreement or any other Loan
Document, any investigation by or knowledge of any Lender Party, the making of
any Loan, the issuance of any Letter of Credit or any other event or condition
whatever.

                  10.10. COUNTERPARTS. This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts each of which, when so executed, shall be deemed an original, but
all such counterparts shall constitute but one and the same instrument.

                  10.11. LIMITATION ON PAYMENTS. The parties hereto intend to
conform to all applicable Laws in effect from time to time limiting the maximum
rate of interest that may be charged or collected. Accordingly, notwithstanding
any other provision hereof or of any other Loan Document, the Borrower shall not
be required to make any payment to or for the account of any Lender, and each
Lender shall refund any payment made by the Borrower, to the extent that such
requirement or such failure to refund would violate or conflict with nonwaivable
provisions of applicable Laws limiting the maximum amount of interest which may
be charged or collected by such Lender.

                  10.12. SET-OFF. The Borrower hereby agrees that if any Loan
Obligation of the Borrower shall be due and payable (by acceleration or
otherwise), each Lender Party shall have the right, without notice to the
Borrower, to set-off against and to appropriate and apply to such Loan
Obligation any obligation of any nature owing to the Borrower by such Lender
Party, including but not limited to all 


                                      -72-
<PAGE>   85

deposits (whether time or demand, general or special, provisionally credited or
finally credited, whether or not evidenced by a certificate of deposit) now or
hereafter maintained by the Borrower with such Lender Party. Such right shall be
absolute and unconditional in all circumstances and, without limitation, shall
exist whether or not such Lender Party or any other Person shall have given
notice or made any demand to the Borrower or any other Person, whether such
obligation owed to the Borrower is contingent, absolute, matured or unmatured
(it being agreed that such Lender Party may deem such obligation to be then due
and payable at the time of such setoff), and regardless of the existence or
adequacy of any collateral, guaranty or any other security, right or remedy
available to any Lender Party or any other Person. The Borrower hereby agrees
that, to the fullest extent permitted by law, any Participant and any branch,
subsidiary or affiliate of any Lender Party or any Participant shall have the
same rights of set-off as a Lender as provided in this Section 10.12 (regardless
of whether such Participant, branch, subsidiary or affiliate would otherwise be
deemed in privity with or a direct creditor of the Borrower). The rights
provided by this Section 10.12 are in addition to all other rights of set-off
and banker's lien and all other rights and remedies which any Lender Party (or
any such Participant, branch, subsidiary or affiliate) may otherwise have under
this Agreement, any other Loan Document, at law or in equity, or otherwise, and
nothing in this Agreement or any Loan Document shall be deemed a waiver or
prohibition of or restriction on the rights of set-off or bankers' lien of any
such Person.

                  10.13. SHARING OF COLLECTIONS. Subject to Section 2.06 of the
Collateral Agency Agreement, the Lenders hereby agree among themselves that if
any Lender shall receive (by voluntary payment, realization upon security,
set-off or from any other source) any amount on account of the Loans, interest
thereon, or any other Loan Obligation contemplated by this Agreement or the
other Loan Documents to be made by the Borrower ratably to all Lenders in
greater proportion than any such amount received by any other Lender, then the
Lender receiving such proportionately greater payment shall notify each other
Lender and the Administrative Agent of such receipt, and equitable adjustment
will be made in the manner stated in this Section so that, in effect, all such
excess amounts will be shared ratably among all of the Lenders. The Lender
receiving such excess amount shall purchase (which it shall be deemed to have
done simultaneously upon the receipt of such excess amount) for cash from the
other Lenders a participation in the applicable Loan Obligations owed to such
other Lenders in such amount as shall result in a ratable sharing by all Lenders
of such excess amount (and to such extent the receiving Lender shall be a
Participant). If all or any portion of such excess amount is thereafter
recovered from the Lender making such purchase, such purchase shall be rescinded
and the purchase price restored to the extent of such recovery, together with
interest or other amounts, if any, required by Law to be paid by the Lender
making such purchase. The Borrower hereby consents to and confirms the foregoing
arrangements. Each Participant shall be bound by this Section as fully as if it
were a Lender hereunder.

                  10.14. SUCCESSORS AND ASSIGNS; PARTICIPATIONS; ASSIGNMENTS.

                  (a) SUCCESSORS AND ASSIGNS. This Agreement shall be binding
upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that the Borrower may not assign or transfer any
of its rights hereunder without the prior written consent of all the Lenders and
the Administrative Agent, and any purported assignment or transfer without such
consent shall be void.

                  (b) PARTICIPATIONS. Any Lender may, in the ordinary course of
its business and in accordance with applicable Law, at any time sell
participations to one or more commercial banks or other Persons (each a
"Participant") in all or a portion of its rights and obligations under this
Agreement and the other Loan Documents (including, without limitation, all or a
portion of its Commitments and the Loans owing to it and any Note held by it);
provided, that


                                      -73-
<PAGE>   86

                  (i) any such Lender's obligations under this Agreement and the
         other Loan Documents shall remain unchanged,

                  (ii) such Lender shall remain solely responsible to the other
         parties hereto for the performance of such obligations,

                  (iii) the parties hereto shall continue to deal solely and
         directly with such Lender in connection with such Lender's rights and
         obligations under this Agreement and each of the other Loan Documents,
         and

                  (iv) such Participant shall, by accepting such Participation,
         be bound by the provisions of Section 10.13, and

                  (v) if such Participant is not already a Participant or a
         Lender, and if such Participation gives such Participant any voting
         rights (other than on matters described in clauses (a) through (g),
         inclusive, of Section 10.03), such Participation shall be subject to
         consent of the Administrative Agent, the Issuing Bank Representative
         and the Swingline Lender and the Borrower pursuant to clause (i) of
         Section 10.14(c) as if such Participation were an assignment described
         therein.

The Borrower agrees that any such Participant shall be entitled to the benefits
of Sections 2.10, 2.11, 10.06 and 10.12 with respect to its participation in the
Commitments and the Loans outstanding from time to time; provided, that no such
Participant shall be entitled to receive any greater amount pursuant to such
Sections than the transferor Lender would have been entitled to receive in
respect of the amount of the participation transferred to such Participant had
no such transfer occurred.

                  (c) ASSIGNMENTS. Any Lender may, in the ordinary course of its
business and in accordance with applicable Law, at any time assign all or a
portion of its rights and obligations as Lender under this Agreement and the
other Loan Documents (including, without limitation, all or any portion of its
Commitments and Loans owing to it and any Note held by it) to any Lender or to
one or more additional commercial banks or other Persons (each a "Purchasing
Lender"); provided, that

                  (i) any such assignment to a Purchasing Lender which is not a
         Lender or an affiliate of the assigning Lender shall be made only with
         the consent of the Borrower, the Administrative Agent, the Issuing Bank
         Representative and the Swingline Lender (which consent may not be
         unreasonably withheld or delayed);

                  (ii) if a Lender makes such an assignment of less than all of
         its then remaining rights and obligations under this Agreement and the
         other Loan Documents, such transferor Lender shall retain, after such
         assignment, a minimum principal amount of $10,000,000 of the
         Commitments or Loans then outstanding, and after giving effect to such
         assignment the Purchasing Lender shall have a minimum aggregate
         principal amount of $10,000,000 of the Commitments or Loans then
         outstanding,

                  (iii) each such assignment shall be of a constant, and not a
         varying, percentage of all of the Revolving Credit Commitments, Term
         Loan Commitments and Loans of the transferor Lender, and of all of the
         transferor Lender's related rights and obligations under this Agreement
         and the other Loan Documents (provided, that such assignment may, but
         need not, include rights of the transferor Lender in respect of
         outstanding Competitive Bid Loans), and


                                      -74-
<PAGE>   87

                  (iv) each such assignment shall be made pursuant to a Transfer
         Supplement in substantially the form of Exhibit C to this Agreement,
         duly completed (a "Transfer Supplement").

In order to effect any such assignment, the transferor Lender and the Purchasing
Lender shall execute and deliver to the Administrative Agent a duly completed
Transfer Supplement (including any consents required by the foregoing clause
(i)), together with any Note or Notes subject to such assignment, and a
processing and recording fee of $3,500; and, upon receipt thereof, the
Administrative Agent shall accept such Transfer Supplement. Upon receipt of the
Purchase Price Receipt Notice referred to in such Transfer Supplement, the
Administrative Agent shall record such acceptance in the Register. Upon such
execution, delivery, acceptance and recording, from and after the close of
business at the Administrative Agent's Office on the Transfer Effective Date
specified in such Transfer Supplement

                  (x) the Purchasing Lender shall be a party hereto and, to the
         extent provided in such Transfer Supplement, shall have the rights and
         obligations of a Lender hereunder, and

                  (y) the transferor Lender thereunder shall be released from
         its obligations under this Agreement to the extent so transferred (and,
         in the case of an Transfer Supplement covering all or the remaining
         portion of a transferor Lender's rights and obligations under this
         Agreement, such transferor Lender shall cease to be a party to this
         Agreement) from and after the Transfer Effective Date.

On or prior to the Transfer Effective Date specified in a Transfer Supplement,
the Borrower, at its expense, shall execute and deliver to the Administrative
Agent (for delivery to the Purchasing Lender) new Notes evidencing such
Purchasing Lender's assigned Commitments and Loans and (for delivery to the
transferor Lender) replacement Notes evidencing the Commitments and Loans
retained by the transferor Lender (such Notes to be in exchange for, but not in
payment of, those Notes then held by such transferor Lender). Each such Note
shall be dated the date and be substantially in the form of the predecessor
Note. The Administrative Agent shall mark the predecessor Notes "exchanged" and
deliver them to the Borrower. Accrued interest and accrued fees shall be paid to
the Purchasing Lender at the same time or times provided in the predecessor
Notes and this Agreement.

                  (d) REGISTER. The Administrative Agent shall maintain at its
office a copy of each Transfer Supplement delivered to it and a register (the
"Register") for the recordation of the names and addresses of the Lenders and
the Commitment of, and principal amount of the Loans owing to, each Lender from
time to time. The entries in the Register shall be conclusive absent manifest
error and the Borrower and each Lender Party may treat each person whose name is
recorded in the Register as a Lender hereunder for all purposes of the
Agreement. The Register shall be available for inspection by the Borrower or any
Lender at any reasonable time and from time to time upon reasonable prior
notice.

                  (e) FINANCIAL AND OTHER INFORMATION. Subject to Section 10.15,
the Borrower authorizes the Administrative Agent and each Lender to disclose to
any Participant or Purchasing Lender, or prospective Participant or Purchasing
Lender, any and all financial and other information delivered to, received by,
or otherwise in the possession of, such Person from time to time relating to the
Borrower, its Subsidiaries and affiliates, or the matters contemplated by the
Loan Documents. At the request of any Lender, the Borrower, at the Borrower's
expense, shall provide to each prospective transferee the conformed copies of
documents referred to in Section 4 of the form of Transfer Supplement.

                  (f) SYNDICATION. The Borrower shall, at the reasonable request
of the Administrative Agent or each Syndication Agent from time to time, at the
Borrower's expense, use all reasonable efforts to 


                                      -75-
<PAGE>   88

cooperate with their respective syndication efforts, including, without
limitation, (i) providing information packages from time to time for delivery to
prospective Participants and Purchasing Lenders, at Borrower's expense, and (ii)
causing appropriate officers, representatives and experts to meet with
prospective Participants and Purchasing Lenders from time to time as reasonably
requested by the Administrative Agent or any Syndication Agent.

                  (g) ASSIGNMENTS TO FEDERAL RESERVE BANK. Any Lender may at any
time assign all or any portion of its rights under this Agreement, including
without limitation any Loans owing to it and any Note held by it, to a Federal
Reserve Bank. No such assignment shall relieve the transferor Lender from any of
its obligations hereunder.

                  10.15. CONFIDENTIALITY. Each Lender Party agrees to take
reasonable precautions to maintain the confidentiality of information designated
in writing by the Borrower as confidential and provided to it by the Borrower in
connection with this Agreement; provided, that any Lender Party may disclose
such information (i) at the request of any bank regulatory authority or other
Governmental Authority or in connection with an examination of such Lender Party
by any such Governmental Authority, (ii) pursuant to subpoena or other court
process, (iii) to the extent such Lender Party is required (or believes in good
faith, following receipt of advice of counsel, that it is required) to do so in
accordance with any applicable Law, (iv) to such Lender Party's independent
auditors and other professional advisors, (v) in connection with the enforcement
of any of such Lender Party's rights under or in connection with any Loan
Document, (vi) to the extent that such information becomes publicly available
other than by breach of this Agreement, or becomes available to such Lender
Party on a non-confidential basis from a source other than the Borrower, (vii)
to any other Lender Party, and (viii) to any actual or potential Participant or
Purchasing Lender; so long as, in the case of clauses (iv), (vii) and (viii),
such Person has been notified that, by receiving any such confidential
information, it is subject to the foregoing confidentiality requirements to the
same extent as such Lender Party.

                  10.16. COLLATERAL. Each of the Lenders represents to the
Administrative Agent, Collateral Agent and each of the other Lenders that it in
good faith is not relying upon any Margin Stock as collateral in the extension
or maintenance of the credit provided for in this Agreement. Each of the Lenders
acknowledges that the proceeds of the extension of credit hereunder will be used
as provided in Section 6.09.

                  10.17. GOVERNING LAW; SUBMISSION TO JURISDICTION; WAIVER OF
JURY TRIAL; LIMITATION OF Liability.

                  (a) GOVERNING LAW. THIS AGREEMENT AND ALL OTHER LOAN DOCUMENTS
(EXCEPT TO THE EXTENT, IF ANY, OTHERWISE EXPRESSLY STATED IN SUCH OTHER LOAN
DOCUMENTS) SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE
LAWS OF THE COMMONWEALTH OF PENNSYLVANIA, WITHOUT REGARD TO CHOICE OF LAW
PRINCIPLES.

                  (b) CERTAIN WAIVERS. THE BORROWER HEREBY IRREVOCABLY AND
UNCONDITIONALLY:

                  (I) AGREES THAT ANY ACTION, SUIT OR PROCEEDING BY ANY PERSON
         ARISING FROM OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
         OR ANY STATEMENT, COURSE OF CONDUCT, ACT, OMISSION, OR EVENT OCCURRING

         LITIGATION") MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT
         JURISDICTION SITTING IN ALLEGHENY COUNTY, PENNSYLVANIA, SUBMITS TO THE
         JURISDICTION OF SUCH COURTS, AND TO THE FULLEST EXTENT PERMITTED BY LAW
         AGREES THAT IT WILL NOT BRING ANY RELATED LITIGATION IN ANY OTHER FORUM

                                      -76-
<PAGE>   89

         SHALL AFFECT THE RIGHT OF ANY LENDER PARTY TO BRING ANY ACTION, SUIT OR
         PROCEEDING IN ANY OTHER FORUM);

                  (II) WAIVES ANY OBJECTION WHICH IT MAY HAVE AT ANY TIME TO THE
         LAYING OF VENUE OF ANY RELATED LITIGATION BROUGHT IN ANY SUCH COURT,
         WAIVES ANY CLAIM THAT ANY SUCH RELATED LITIGATION HAS BEEN BROUGHT IN
         AN INCONVENIENT FORUM, AND WAIVES ANY RIGHT TO OBJECT, WITH RESPECT TO
         ANY RELATED LITIGATION BROUGHT IN ANY SUCH COURT, THAT SUCH COURT DOES
         NOT HAVE JURISDICTION OVER THE BORROWER;

                  (III) CONSENTS AND AGREES TO SERVICE OF ANY SUMMONS, COMPLAINT
         OR OTHER LEGAL PROCESS IN ANY RELATED LITIGATION BY REGISTERED OR
         CERTIFIED U.S. MAIL, POSTAGE PREPAID, TO THE BORROWER AT THE ADDRESS
         FOR NOTICES DESCRIBED IN SECTION 10.05, AND CONSENTS AND AGREES THAT
         SUCH SERVICE SHALL CONSTITUTE IN EVERY RESPECT VALID AND EFFECTIVE
         SERVICE (BUT NOTHING HEREIN SHALL AFFECT THE VALIDITY OR EFFECTIVENESS
         OF PROCESS SERVED IN ANY OTHER MANNER PERMITTED BY LAW); AND

                  (IV) WAIVES THE RIGHT TO TRIAL BY JURY IN ANY RELATED
LITIGATION.

                  (c) LIMITATION OF LIABILITY. TO THE FULLEST EXTENT PERMITTED
BY LAW, NO CLAIM MAY BE MADE BY THE BORROWER AGAINST ANY LENDER PARTY OR ANY
AFFILIATE, DIRECTOR, OFFICER, EMPLOYEE, ATTORNEY OR AGENT OF ANY OF THEM FOR ANY
SPECIAL, INCIDENTAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES IN RESPECT OF
ANY CLAIM ARISING FROM OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT
OR ANY STATEMENT, COURSE OF CONDUCT, ACT, OMISSION, OR EVENT OCCURRING IN

OTHER THEORY OF LIABILITY). THE BORROWER HEREBY WAIVES, RELEASES AND AGREES NOT
TO SUE UPON ANY CLAIM FOR ANY SUCH DAMAGES, WHETHER SUCH CLAIM PRESENTLY EXISTS
OR ARISES HEREAFTER AND WHETHER OR NOT SUCH CLAIM IS KNOWN OR SUSPECTED TO EXIST
IN ITS FAVOR.

         Equity Hybrid Securities of the Borrower and its Subsidiaries for such

         for such period of (i) Consolidated Net Income, (ii) interest expense

         Consolidated Capital Expenditures, divided by (b) Consolidated Adjusted

         (or any other acquisition of a business) occurs during such period,

         calculation of the Consolidated Adjusted Interest Expense with respect
         to Indebtedness or other obligations issued or incurred in connection

         thereon shall be calculated on the basis of an interest rate per annum

         plus an Applicable Margin determined on the basis of the Borrower's

         Borrower issues capital stock for cash during such period and promptly
         applies the net proceeds thereof to reduction of Indebtedness of the
         Borrower or its consolidated Subsidiaries, Consolidated Adjusted
         Interest Expense for such period shall be calculated on a pro forma
         basis as if such reduction of Indebtedness had been made as of the
         first day of such period.

                  "Consolidated Leverage Ratio" as of the last day of any fiscal
         quarter shall mean (a) aggregate Indebtedness of the Borrower and its
         consolidated Subsidiaries as of such day, divided by (b) Consolidated
         EBITDA for the four fiscal quarters ending on such day, considered as a
         single accounting period. If the Acquisition (or any other acquisition
         of a business) occurs during such period, Consolidated EBITDA shall be
         calculated on a pro forma basis as if the 


                                      A-4

         Acquisition (or such other acquisition) had been made as of the first
         day of such period. Consolidated Leverage Ratio on the Closing Date
         shall mean (x) aggregate Indebtedness of the Borrower and its
         consolidated Subsidiaries as of such day, after giving effect to the
         Acquisition and the Indebtedness incurred in connection therewith (and
         including, on a pro forma basis, all other Indebtedness to be incurred
         in connection with the Acquisition, to the extent not incurred on the
         Closing Date), divided by (y) Consolidated EBITDA as of September 30,
         1997, calculated on a pro forma basis as if the Acquisition (and any

     A. Kennametal Inc., a Pennsylvania corporation (the "Borrower") has entered
into a Credit Agreement of even date herewith with the Lenders parties thereto
from time to time and Mellon Bank, N.A., as Administrative Agent (as amended,
modified or supplemented from time to time, the "Credit Agreement"). Each
Subsidiary Guarantor will derive substantial direct and indirect benefit from
the transactions contemplated by the Credit Agreement, and each Subsidiary
Guarantor may receive a portion of the proceeds of extensions of credit under
the Credit Agreement from time to time.

     B. The Borrower, the Subsidiary Guarantors, certain Lender Parties (as
defined therein), and certain Swap Parties, and Mellon Bank, N.A., as Collateral
Agent, have entered into a Collateral Agency Agreement of even date herewith (as
amended, modified or supplemented from time to time, the "Collateral Agency
Agreement"). Pursuant to the Collateral Agency Agreement, the Collateral Agent
has agreed to serve as the collateral agent for the Facility Parties (as defined
therein) with respect to certain direct and indirect security (including this
Agreement) for obligations of the Borrower under or in connection with the
Credit Agreement and the other Obligations referred to in the Collateral Agency
Agreement.

     C. It is a condition precedent to the extension of credit under the Credit
Agreement that the Subsidiary Guarantors execute and deliver this Agreement.
This Agreement, among other things, is made by the Subsidiary Guarantors to
induce the Lender Parties to enter into the Loan Documents (as defined in the
Credit Agreement) and to induce the Lender Parties to extend credit under the
Credit Agreement.

     D. Each Subsidiary Guarantor acknowledges that the Facility Parties have
relied and will rely on this Agreement in entering into the Secured Party
Documents and extending credit under the Credit Agreement. Each Subsidiary
Guarantor further acknowledges that it has, independently and without reliance
upon the Secured Parties or any representation by or other information from the
Secured Parties, made its own credit analysis and decision to enter into this
Agreement.

     NOW, THEREFORE, in consideration of the premises, and intending to be
legally bound, each Subsidiary Guarantor hereby agrees as follows:


                                    ARTICLE I
                                   DEFINITIONS

     1.01. DEFINITIONS. Capitalized terms not otherwise defined herein shall

                                   ARTICLE II
                             GUARANTY AND SURETYSHIP

     2.01. GUARANTY AND SURETYSHIP. Each Subsidiary Guarantor hereby absolutely,
unconditionally and irrevocably guarantees and becomes surety for the full and
punctual payment and performance of the Obligations as and when such payment or
performance shall become due (at scheduled maturity, by acceleration or
otherwise) in accordance with the terms of the Secured Party Documents. This
Agreement is an agreement of suretyship as well as of guaranty, is a guarantee
of payment and performance and not merely of collectibility, and is in no way
conditioned upon any attempt to collect from or proceed against the Borrower,
any other Subsidiary Guarantor or any other Person or any other event or
circumstance. The obligations of each Subsidiary Guarantor under this Agreement
are direct and primary obligations of such Subsidiary Guarantor and are
independent of the Obligations, and a separate action or actions may be brought
against such Subsidiary Guarantor regardless of whether action is brought
against the Borrower, any other Subsidiary Guarantor or any other Person or
whether the Borrower, any other Subsidiary Guarantor or any other Person is
joined in any such action or actions.

     2.02. OBLIGATIONS ABSOLUTE. Each Subsidiary Guarantor agrees that the
Obligations will be paid and performed strictly in accordance with the terms of
the Secured Party Documents, regardless of any Law, regulation or order now or
hereafter in effect in any jurisdiction affecting the Obligations, any of the
terms of the Secured Party Documents or the rights of any Secured Party or any
other Person with respect thereto. The obligations of each Subsidiary Guarantor
under this Agreement shall be absolute, unconditional and irrevocable,
irrespective of any of the following:

          (a) any lack of legality, validity, enforceability, allowability (in a
     bankruptcy, insolvency, reorganization, dissolution or similar proceeding,
     or otherwise), or any avoidance or subordination, in whole or in part, of
     any Secured Party Document or any of the Obligations;

          (b) any change in the amount, nature, time, place or manner of payment
     or performance of, or in any other term of, any of the Obligations (whether
     or not such change is contemplated by the Secured Party Documents as
     presently constituted, and specifically including any increase in the
     Obligations, whether resulting from the extension of additional credit to
     the Borrower or otherwise), any execution of any additional Secured Party
     Documents, or any amendment or waiver of or any consent to departure from
     any Secured Party Document;

          (c) any taking, exchange, release, impairment or nonperfection of any
     collateral, or any taking, release, impairment or amendment or waiver of or
     consent to departure from any other guaranty or other direct or indirect
     security for any of the Obligations;

          (d) any manner of application of collateral or other direct or
     indirect security for any of the Obligations, or proceeds thereof, to any
     of the Obligations or to other obligations secured thereby, or any manner
     of sale or other disposition of any collateral for any of the Obligations
     or any other assets of any Loan Party;

          (e) any impairment by any Secured Party or any other Person of any
     recourse of such Subsidiary Guarantor against any Loan Party or any other
     Person, or any other impairment by any Secured Party or any other Person of
     the suretyship status of such Subsidiary Guarantor;



                                     - 2 -
<PAGE>   122


          (f) any bankruptcy, insolvency, reorganization, dissolution or similar
     proceedings with respect to, or any change, restructuring or termination of
     the corporate structure or existence of, any Loan Party, such Subsidiary
     Guarantor or any other Person;

          (g) any failure of any Secured Party or any other Person to disclose
     to such Subsidiary Guarantor any information pertaining to the business,
     operations, condition (financial or other) or prospects of any Loan Party
     or any other Person, or to give any other notice, disclosure or demand; or

          (h) any other event or circumstance (excluding only the defense of
     full, strict and indefeasible payment and performance) that might otherwise
     constitute a defense available to, a discharge of, or a limitation on the
     obligations of, any Loan Party, such Subsidiary Guarantor or a guarantor or
     surety.

     2.03. WAIVERS, ETC. Each Subsidiary Guarantor hereby irrevocably waives any
defense to or limitation on its obligations under this Agreement arising out of
or based upon any matter referred to in Section 2.02. Without limiting the
generality of the foregoing, each Subsidiary Guarantor hereby irrevocably waives
each of the following:

          (a) all notices, disclosures and demands of any nature which otherwise
     might be required from time to time to preserve intact any rights against
     such Subsidiary Guarantor, including (i) any notice of any event or
     circumstance described in Section 2.02, (ii) any notice required by any
     law, regulation or order now or hereafter in effect in any jurisdiction,
     (iii) any notice of nonpayment, nonperformance, dishonor, or protest under
     any Secured Party Document or any of the Obligations, (iv) any notice of
     the incurrence of any Obligation, (v) any notice of any default or any
     failure on the part of any Loan Party or any other Person to comply with
     any Secured Party Document or any of the Obligations or any direct or
     indirect security for any of the Obligations, and (vi) any notice of any
     information pertaining to the business, operations, condition (financial or
     other) or prospects of any Loan Party or any other Person;

          (b) any right to any marshalling of assets, to the filing of any claim
     against any Loan Party or any other Person in the event of any bankruptcy,
     insolvency, reorganization, dissolution or similar proceeding, or to the
     exercise against any Loan Party or any other Person of any other right or
     remedy under or in connection with any Secured Party Document or any of the
     Obligations or any direct or indirect security for any of the Obligations;
     any requirement of promptness or diligence on the part of the Secured
     Parties or any other Person; any requirement to exhaust any remedies under
     or in connection with, or to mitigate the damages resulting from default
     under, any Secured Party Document or any of the Obligations or any direct
     or indirect security for any of the Obligations; and any requirement of
     acceptance of this Agreement, and any requirement that such Subsidiary
     Guarantor receive notice of such acceptance; and

          (c) any defense or other right arising by reason of any Law now or
     hereafter in effect in any jurisdiction pertaining to election of remedies
     (including anti-deficiency laws, "one action" laws or similar laws), or by
     reason of any election of remedies or other action or inaction by the
     Secured Parties (including commencement or completion of any judicial
     proceeding or nonjudicial sale or other action in respect of collateral
     security for any of the Obligations), which results in denial or impairment
     of the right of the Secured Parties to seek a deficiency against any Loan
     Party any other Person, or which otherwise discharges or impairs any of the
     Obligations or any recourse of such Subsidiary Guarantor against any Loan
     Party or any other Person.

     2.04. REINSTATEMENT. This Agreement shall continue to be effective, or be
automatically reinstated, as the case may be, if at any time payment of any of
the Obligations is avoided, rescinded or must otherwise be returned by any
Secured Party for any reason, all as though such payment had not been made.

     2.05. NO STAY. Without limiting the generality of any other provision of
this Agreement, if any acceleration of the time for payment or performance of
any Obligation, or any condition to any such acceleration, shall at any time be
stayed, enjoined or prevented for any reason (including stay or injunction
resulting from the pendency against any Loan Party or any other Person of a
bankruptcy, insolvency, reorganization, dissolution or similar proceeding), each
Subsidiary Guarantor agrees that, for purposes of this Agreement and its
obligations hereunder, at the option of the Collateral Agent, such Obligation
shall be deemed to have been accelerated and such condition to acceleration
shall be deemed to have been met.

     2.06. PAYMENTS. All payments to be made by each Subsidiary Guarantor
pursuant to this Agreement (other than payments to a Secured Party under Section
2.11) shall be made to the Collateral Agent at the time prescribed for payments
of the underlying Obligation in the applicable Secured Party Document, without
setoff, counterclaim, withholding or other deduction of any nature. The
Collateral Agent shall deposit such payments received by it into the Shared
Collateral Account.

     2.07. SUBROGATION, ETC. Any rights which any Subsidiary Guarantor may have
or acquire by way of subrogation, reimbursement, restitution, exoneration,
contribution or indemnity, and any similar rights (whether arising by operation
of law, by agreement or otherwise), against the Borrower, any other Subsidiary
Guarantor or any other Person arising from the existence, payment, performance
or enforcement of any of the obligations of such Subsidiary Guarantor under or
in connection with this Agreement, shall be subordinate in right of payment to
the Obligations, and such Subsidiary Guarantor shall not exercise any such
rights until all Obligations and all other obligations under this Agreement have
been paid in cash and performed in full and all commitments to extend credit
under, and all Letters of Credit issued under, the Secured Party Documents shall
have terminated. If, notwithstanding the foregoing, any amount shall be received
by a Subsidiary Guarantor on account of any such rights at any time prior to the
time at which all Obligations and all other obligations under this Agreement
shall have been paid in cash and performed in full and all commitments to extend
credit under, and all Letters of Credit issued under, the Secured Documents
shall have terminated, such amount shall be held by such Subsidiary Guarantor in
trust for the benefit of the Secured Parties, segregated from other funds held
by such Subsidiary Guarantor, and shall be forthwith delivered to the Collateral
Agent in the exact form received by such Subsidiary Guarantor (with any
necessary endorsement), to be applied to the Obligations, whether matured or
unmatured, in such order as the Secured Party may elect, or to be held by the
Collateral Agent on behalf of the Secured Parties as security for the
Obligations and disposed of by the Collateral Agent in accordance with the
Collateral Agency Agreement.

     2.08. CONTINUING AGREEMENT. This Agreement is a continuing guaranty and
shall continue in full force and effect until all Obligations and all other
amounts payable under this Agreement have been paid in cash and performed in
full, and all commitments to extend credit under, and all Letters of Credit
issued under, the Secured Party Documents have terminated, subject in any event
to reinstatement in accordance with Section 2.04. Without limiting the
generality of the foregoing, each Subsidiary Guarantor hereby irrevocably waives
any right to terminate or revoke this Agreement.

     2.09. LIMITATION ON PAYMENTS. The parties hereto intend to conform to all
applicable Laws limiting the maximum rate of interest that may be charged or
collected by the Secured Parties from any Subsidiary Guarantor. Accordingly,
notwithstanding any other provision hereof, a Subsidiary 




                                     - 4 -
<PAGE>   124


Guarantor shall not be required to make any payment to or for the account of a
Secured Party, and such Secured Party shall refund any payment made by such
Subsidiary Guarantor, to the extent that such requirement or such failure to
refund would violate or conflict with mandatory and nonwaivable provisions of
applicable Law limiting the maximum amount of interest which may be charged or
collected by such Secured Party from such Subsidiary Guarantor.

     2.10. LIMITATION ON OBLIGATIONS. Notwithstanding any other provision
hereof, to the extent that mandatory and nonwaivable provisions of applicable
Law pertaining to fraudulent transfer or fraudulent conveyance otherwise would
render the full amount of the obligations of a Subsidiary Guarantor under this
Agreement avoidable, invalid or unenforceable, the obligations of such
Subsidiary Guarantor under this Agreement shall be limited to the maximum amount
which does not result in such avoidability, invalidity or unenforceability. In
any action, suit or proceeding pertaining to this Agreement, the burden of
proof, by clear and convincing evidence, shall be on the Person claiming that
this Section 2.10 applies to limit any obligation of such Subsidiary Guarantor
under this Agreement, or claiming that any obligation of such Subsidiary
Guarantor under this Agreement is avoidable, invalid or unenforceable, as to
each element of such claim.

     2.11. TAXES.

     (a) PAYMENTS NET OF TAXES. All payments made by each Subsidiary Guarantor
under this Agreement or any other Secured Party Document shall be made free and
clear of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings, and all liabilities with respect
thereto, excluding (x) in the case of each Secured Party, net income taxes
imposed on such Secured Party by the United States, and net income taxes and
franchise taxes imposed on such Secured Party by the jurisdiction under the Laws
of which such Secured Party is organized or by any political subdivision
thereof, and (y) in the case of each Secured Party, net income taxes and
franchise taxes imposed on such Secured Party by the jurisdiction in which is
located the Secured Party's Applicable Lending Office or other office which
makes or books a particular extension of credit or transaction under the Secured
Party Documents or any political subdivision thereof (all such non-excluded
taxes, levies, imposts, deduction, charges, withholdings and liabilities being
referred to as "Taxes"). If any Subsidiary Guarantor shall be required by Law to
deduct any Taxes from or in respect of any sum payable under this Agreement or
any other Secured Party Document to any Secured Party, (i) the sum payable shall
be increased as may be necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
2.11) such Secured Party receives an amount equal to the sum it would have
received had no such deductions been made, (ii) such Subsidiary Guarantor shall
make such deductions, and (iii) such Subsidiary Guarantor shall pay the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable Law.

     (b) OTHER TAXES. Each Subsidiary Guarantor agrees 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 under this Agreement or any
other Secured Party Document to which it is party or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement or any
other Secured Party Document to which it is party (hereinafter referred to as
"Other Taxes").

     (c) INDEMNITY. Each Subsidiary Guarantor hereby indemnifies each Secured
Party for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts
payable under this Section 2.11) paid by such Secured Party and any liability
(including, without limitation, 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 15 days
from the date such Secured Party makes written demand 



                                     - 5 -
<PAGE>   125



therefor (which demand shall identify in reasonable detail the nature and the
amount of Taxes and Other Taxes for which indemnification is being sought).

     (d) RECEIPTS, ETC. Within 30 days after the date of any payment of Taxes or
Other Taxes, each Subsidiary Guarantor will furnish to the Collateral Agent the
original or a certified copy of a receipt evidencing payment thereof.

     (e) OTHER. Without prejudice to the survival of any other agreement of any
Subsidiary Guarantor hereunder, the obligations of each Subsidiary Guarantor
contained in this Section 2.11 shall survive the payment in full of all other
obligations of the Subsidiary Guarantor under this Agreement and the other
Secured Party Documents, termination of all commitments to extend credit under,
and all Letters of Credit issued under, the Secured Party Documents, and all
other events and circumstances. Nothing in this Section 2.11 or otherwise in
this Agreement shall require any Secured Party to disclose to any Subsidiary
Guarantor any of its tax returns (or any other information that it deems to be
confidential or proprietary).

     2.12. RELEASE OF SUBSIDIARY GUARANTOR. Upon the sale or other disposition
of all of the capital stock of and other equity interests in a Subsidiary
Guarantor to a Person or Persons other than the Borrower or a Subsidiary of the
Borrower, which sale or other disposition is in compliance with the Secured
Party Documents, the Collateral Agent will, at such Subsidiary Guarantor's
expense, (x) release such Subsidiary Guarantor from its obligations under this
Agreement, and (y) if such Subsidiary Guarantor is party to a Subsidiary Pledge
Agreement, also release such Subsidiary Guarantor from its obligations under
such Subsidiary Pledge Agreement and release the Liens granted by such
Subsidiary Guarantor in favor of the Collateral Agent under such Subsidiary
Pledge Agreement; provided, however, that (a) at the time of such request and
such release no Event of Default or Potential Default shall have occurred and be
continuing, (b) such Subsidiary Guarantor shall have delivered to the Collateral
Agent and the Administrative Agent, at least five Business Days prior to the
date of the proposed release, a written request for release describing the terms
of the sale or other disposition in reasonable detail, including the price
thereof and any expenses in connection therewith, together with a form for
release for execution by the Collateral Agent and a certification by a
Responsible Officer of the Borrower to the effect that the transaction is in
compliance with the Secured Party Documents and as to such other matters as the
Collateral Agent may in good faith request, (c) the Administrative Agent shall
not have given to the Collateral Agent prior to the proposed release a notice to
the effect that the conditions set forth in this Section 2.12 have not been
satisfied and specifically requesting that the Collateral Agent not effect such
release, and (d) the proceeds of any such sale or other disposition required to
be applied in accordance with Section 2.07 of the Credit Agreement, or any
successor provision of similar import, shall be paid to, or in accordance with
the instructions of, the Administrative Agent in accordance with the Credit
Agreement. The obligations of the Subsidiary Guarantor under Sections 2.11 and
5.04 of this Agreement and the obligations of the Subsidiary Guarantor under
Section 6.04 of the Subsidiary Pledge Agreement shall survive any such release.


                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

     3.01. CREDIT AGREEMENT. The provisions of Article IV of the Credit
Agreement are hereby incorporated by reference (together with all related

Subsidiary Guarantor or any Subsidiary of a Subsidiary Guarantor. Each
Subsidiary Guarantor hereby represents and warrants to the Secured Parties as
provided therein.

<PAGE>   126



     3.02. REPRESENTATIONS AND WARRANTIES REMADE AT EACH EXTENSION OF CREDIT.
Each request (including any deemed request) by the Borrower for any extension of
credit under any Secured Party Document shall be deemed to constitute a
representation and warranty by each Subsidiary Guarantor to the Secured Parties
that the representations and warranties made by such Subsidiary Guarantor in
this Article III are true and correct on and as of the date of such request with
the same effect as though made on and as of such date. Failure by the Collateral
Agent to receive notice from a Subsidiary Guarantor to the contrary before any
extension of credit under any Secured Party Document shall constitute a further
representation and warranty by such Subsidiary Guarantor to the Secured Parties
that the representations and warranties made by such Subsidiary Guarantor in
this Article III are true and correct on and as of the date of such extension of
credit with the same effect as though made on and as of such date.


                                   ARTICLE IV
                                    COVENANTS

     4.01. COVENANTS GENERALLY. Reference is hereby made to the provisions of
Articles VI and VII of the Credit Agreement (together with all related
definitions and cross-references). Each Subsidiary Guarantor hereby agrees that,
to the extent such provisions impose upon the Borrower a duty to cause any
Subsidiary Guarantor to do or refrain from doing certain acts or things or to
meet or refrain from meeting certain conditions, such Subsidiary Guarantor shall
do or refrain from doing such acts or things, or meet or refrain from meeting
such conditions, as the case may be.


                                    ARTICLE V
                                  MISCELLANEOUS

     5.01. AMENDMENTS, ETC. No amendment to or waiver of any provision of this
Agreement, and no consent to any departure by any Subsidiary Guarantor herefrom,
shall in any event be effective unless in a writing manually signed by or on
behalf of such Subsidiary Guarantor and the Collateral Agent. Any such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. Such amendments, waivers and consents shall be made in
accordance with, and shall be subject to, Section 6.01 of the Collateral Agency
Agreement.

     5.02. NO IMPLIED WAIVER; REMEDIES CUMULATIVE. No delay or failure of the
Collateral Agent or any other Secured Party in exercising any right or remedy
under this Agreement shall operate as a waiver thereof; nor shall any single or
partial exercise of any such right or remedy preclude any other or further
exercise thereof or the exercise of any other right or remedy. The rights and
remedies of the Collateral Agent or any other Secured Party under this Agreement
are cumulative and not exclusive of any other rights or remedies available
hereunder, under any other agreement, at law, or otherwise.

     5.03. NOTICES. Except to the extent, if any, otherwise expressly provided
herein, all notices and other communications (collectively, "notices") under
this Agreement shall be given, shall be effective, and may be relied upon, in
the same way as notices under the Collateral Agency Agreement.

     5.04. EXPENSES. Each Subsidiary Guarantor agrees to pay upon demand all
reasonable expenses (including reasonable fees and expenses of counsel) which
the Collateral Agent or any other Secured Party may incur from time to time
arising from or relating to the administration of, or exercise, enforcement or
preservation of rights or remedies under, this Agreement.

     5.05. ENTIRE AGREEMENT. This Agreement and the other Secured Party
Documents constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and thereof and supersede all prior and
contemporaneous understandings and agreements.

     5.06. SURVIVAL. All representations and warranties of the each Subsidiary
Guarantor contained in or made in connection with this Agreement shall survive,
and shall not be waived by, the execution and delivery of this Agreement, any
investigation by or knowledge of any Secured Party, any extension of credit,
termination of this Agreement, or any other event or circumstance whatsoever.

     5.07. COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, and all such
counterparts shall constitute but one and the same agreement.

     5.08. SETOFF. In the event that any obligation of a Subsidiary Guarantor
now or hereafter existing under this Agreement or any other Secured Party
Document shall have become due and payable, each Secured Party shall have the
right from time to time, without notice to such Subsidiary Guarantor, to set off
against and apply to such due and payable amount any obligation of any nature of
such Secured Party to such Subsidiary Guarantor, including all deposits (whether
time or demand, general or special, provisionally or finally credited, however
evidenced) now or hereafter maintained by such Subsidiary Guarantor with such
Secured Party. Such right shall be absolute and unconditional in all
circumstances and, without limitation, shall exist whether such obligation to
such Subsidiary Guarantor is absolute or contingent, matured or unmatured (it
being agreed that such Secured Party may deem such obligation to be then due and
payable at the time of such setoff), regardless of the offices or branches
through which the parties are acting with respect to the offset obligations, and
regardless of the existence or adequacy of any other direct or indirect security
or any other right or remedy available to such Secured Party. Nothing in this
Agreement or any other Secured Party Document shall be deemed a waiver of or
restriction on any right of setoff or banker's lien available to a Secured Party
under this Section 5.08, at law or otherwise. Each Subsidiary Guarantor hereby
agrees that any affiliate of a Secured Party, and any holder of a participation
in any obligation of such Subsidiary Guarantor under this Agreement, shall have
the same rights of setoff as the Secured Parties as provided in this Section
5.08 (regardless of whether such affiliate or participant otherwise would be
deemed a creditor of such Subsidiary Guarantor).

     5.09. CONSTRUCTION. In this Agreement, unless the context otherwise clearly
requires, references to the plural include the singular, the singular the
plural, and the part the whole; the neuter case includes the masculine and
feminine cases; and "or" is not exclusive. In this Agreement, any references to
property (or similar terms) include any interest in such property (or other item
referred to); "include," "includes," "including" and similar terms are not
limiting; and "hereof," "herein," "hereunder" and similar terms refer to this
Agreement as a whole and not to any particular provision. Section and other
headings in this Agreement, and any table of contents herein, are for reference
purposes only and shall not affect the interpretation of this Agreement in any
respect. Section and other references in this Agreement are to this Agreement
unless otherwise specified. This Agreement has been fully negotiated between the
applicable parties, each party having the benefit of legal counsel, and
accordingly neither any doctrine of construction of guaranties in favor of the
secured party, nor any doctrine of construction of ambiguities against the party
controlling the drafting, shall apply to this Agreement.

     5.10. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon each
Subsidiary Guarantor and its successors and assigns, and shall inure to the
benefit of and be enforceable by the Collateral Agent and the other Secured
Parties and their respective successors and assigns. Without limitation of the
foregoing, each Secured Party (and any successive assignee or transferee) from
time to 



                                     - 8 -
<PAGE>   128


time may assign or otherwise transfer all or any portion of its rights or
obligations under the Secured Party Documents (including all or any portion of
any commitment to extend credit), or any Obligations, to any other Person, and
such Obligations (including any Obligations resulting from extension of credit
by such other Person under or in connection with the Secured Party Documents)
shall be and remain Obligations entitled to the benefit of this Agreement, and
to the extent of its interest in such Obligations such other Person shall be
vested with all the benefits in respect thereof granted to the Secured Party in
this Agreement or otherwise.

     5.11. JOINT AND SEVERAL OBLIGATIONS. The obligations of the Subsidiary
Guarantors hereunder are joint and several obligations of each of them.

     5.12. COLLATERAL AGENCY AGREEMENT. This Agreement is a Shared Security
Document referred to in the Collateral Agency Agreement. The provisions of the

in reasonable detail, including the price thereof and any expenses in connection
therewith, together with a form for release for execution by the Collateral
Agent and a certification by the Grantor to the effect that the transaction is
in compliance with the Secured Party Documents and as to such matters as the
Collateral Agent may in good faith request, (c) the Administrative Agent shall
not have given to the Collateral Agent prior to the proposed release a notice to
the effect that the conditions set forth in this Section 2.03 have not been

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

     The Grantor hereby represents and warrants to each Secured Party as
follows:

     3.01. TITLE. The Grantor is the legal and beneficial owner of the
Collateral, free and clear of any Lien, except for the security interest under
this Agreement in favor of the Collateral Agent securing the Obligations. No
effective financing statement or other item similar in effect covering any
Collateral is on file in any recording office, except such as may be filed in
favor of the Collateral Agent relating to this Agreement.

     3.02. VALIDITY, PERFECTION AND PRIORITY. This Agreement creates a valid
assignment of and security interest in the Collateral in favor of the Collateral
Agent securing the Obligations, which assignment and security interest has been
duly perfected and is prior to all other Liens. All filings and other actions
necessary or desirable to perfect and protect such assignment and security
interest in favor of the Collateral Agent have been duly made and taken.

     3.03. GOVERNMENTAL APPROVALS AND FILINGS. No authorization, approval or
other action by, and no notice to or filing with, any Governmental Authority
(including, without limiting the generality of the foregoing, any Government
Authority in any jurisdiction in which a Designated Subsidiary is organized) is
or will be necessary (a) for the grant by the Grantor of the assignment of and
security interest in the Collateral hereunder or for the execution, delivery or
performance of this Agreement by the Grantor, (b) to ensure the validity,
perfection or priority of the assignment of and security interest in the
Collateral granted hereunder, or (c) for the exercise by the Collateral Agent of
any of its rights or remedies hereunder, except for completion of such actions
as may be required in connection with any disposition of Collateral constituting
securities by Laws affecting the offering and sale of securities generally.

     3.04. OFFICES, ETC. Schedule 3.04 identifies as of the date hereof the
address of the chief executive office of the Grantor and of each place of
business of the Grantor in the jurisdiction containing its chief executive
office. Schedule 3.04 also identifies all changes in the foregoing information
during the one year period ending on the date hereof.

     3.05. NAMES, ETC. During the one year period ending on the date hereof,
neither the Grantor nor any of its direct or indirect predecessors by merger,
consolidation or other corporate 




                                     - 3 -
<PAGE>   137



reorganization is or has been known by or used any corporate or fictitious name
or trade name (other than the corporate name of the Grantor as of the date
hereof), nor has the Grantor or any such predecessor been the subject of any
merger, consolidation or other corporate reorganization, nor has the Grantor or
any such predecessor otherwise changed its name, identity or corporate
structure, except as set forth in Schedule 3.05. For each such direct and
indirect predecessor of the Grantor, Schedule 3.05 also identifies the addresses
referred to in Section 3.04 for all times during such period.

     3.06. TAXES, ETC. There is no tax, levy, impost, deduction, charge,
withholding or similar duty, tax or fee imposed on, or by virtue of the
execution or delivery of, this Agreement or any other document to be furnished
hereunder or in connection herewith.

     3.07. DESIGNATED SUBSIDIARIES AND DESIGNATED PLEDGED SHARES. The Designated
Pledged Shares include all shares of capital stock of, and all other equity
interests in, each Designated Subsidiary owned (beneficially or of record) by
the Grantor; provided, that if the Designated Subsidiary which issued such
Designated Pledged Shares is a Foreign Subsidiary, then, subject to Section
4.01(e), the Designated Pledged Shares need not include more than 65% of the
voting stock of such Foreign Subsidiary. Schedule 3.07 accurately sets forth,
for each class of capital stock or other equity interest to which Designated
Pledged Shares belong, the total number of issued and outstanding shares or
other equity interests of such class, the percentage of such total number of
issued and outstanding shares or other equity interests represented by the
Designated Pledged Shares, the Designated Subsidiary which is the issuer of such
Designated Pledged Shares, and whether such Designated Subsidiary is a Foreign
Subsidiary. The Designated Pledged Shares have been duly authorized and validly
issued and are fully paid and nonassessable. All of the Designated Pledged
Shares are certificated securities (unless expressly stated otherwise on
Schedule 3.07).

     3.08. MARGIN STOCK. None of the Collateral is Margin Stock.

     3.09. REPRESENTATIONS AND WARRANTIES REMADE AT EACH EXTENSION OF CREDIT.
Each request (including any deemed request) by the Grantor for any extension of
credit under any Secured Party Document shall be deemed to constitute a
representation and warranty by the Grantor to the Secured Parties that the
representations and warranties made by the Grantor in this Article III (other
than Sections 3.04 and 3.05) are true and correct on and as of the date of such
request with the same effect as though made on and as of such date. Failure by
the Collateral Agent to receive notice from the Grantor to the contrary before
any extension of credit under any Secured Party Document shall constitute a
further representation and warranty by the Grantor to the Secured Parties that
the representations and warranties made by such Subsidiary Guarantor in this
Article III (other than Sections 3.04 and 3.05) are true and correct on and as
of the date of such extension of credit with the same effect as though made on
and as of such date.


                                   ARTICLE IV

ETC.

     (a) TRANSFERS. The Grantor shall not sell, assign, pledge, lease, transfer
or otherwise dispose of any Collateral (voluntarily or involuntarily, by
operation of Law or otherwise) in contravention of any provision of any other

     (b) OTHER LIENS. The Grantor shall not create or permit to exist any Lien
on any Collateral (voluntarily or involuntarily, by operation of Law or
otherwise).

     (c) ADDITIONAL SHARES. The Grantor shall cause each Designated Subsidiary
not to issue any capital stock or other equity interests in Distributions on or
in substitution for the Designated Pledged Shares issued by such Designated
Subsidiary. All shares of capital stock and other equity interests in any
Designated Subsidiary which the Grantor owns (beneficially or of record) from
time to time shall constitute Collateral, and the Grantor shall immediately
deliver to the Collateral Agent all certificates and instruments constituting or
evidencing any such shares of capital stock and other equity interests;
provided, that the Collateral shall at no time contain more than 65% of the
voting stock of any Designated Subsidiary that is a Foreign Subsidiary except to
the extent such voting stock constitutes Designated Pledged Shares..

     (d) ADDITIONAL DESIGNATED SUBSIDIARIES. The Grantor from time to time may,
and shall to the extent required by Section 6.13(b) of the Credit Agreement or
otherwise in the Secured Party Documents, designate additional Designated
Subsidiaries hereunder. Such designation shall be effected by the Grantor
executing and delivering to the Collateral Agent an Additional Designated
Collateral Supplement in the form of Annex A, duly completed in a manner
satisfactory to the Collateral Agent. Such Additional Designated Collateral
Supplement shall constitute a supplement to Schedule 3.07 to this Agreement.

     (e) DESIGNATED SUBSIDIARY WHICH CEASES TO BE A FOREIGN SUBSIDIARY. In the
event that a Designated Subsidiary ceases to be a Foreign Subsidiary, the
Grantor shall forthwith notify the Collateral Agent of such event and submit and
Additional Designated Collateral Supplement designating as additional Designated
Pledged Shares hereunder, and pledge to the Collateral Agent for the benefit of
the Secured Parties, all shares of stock of, and all other equity interests in,
such Designated Subsidiary.

     4.02. CHANGE IN NAME, ETC. The Grantor shall

     (a) not have, use or be known by any corporate or fictitious name or trade
name (other than its corporate name as of the date hereof and names set forth in
Schedule 3.04), nor be the subject of any merger, consolidation or other
corporate reorganization, nor otherwise change its name, identity or corporate
structure, except, upon 60 days' written notice to the Collateral Agent
(specifically referring to this Section 4.02), and after all actions referred to
in Section 4.04(a) have been completed (it being understood that, in the event
such notice is given by the Grantor and all actions referred to in Section
4.04(a) have been completed to the satisfaction before the end of such 60 day
period, the Collateral Agent shall, at the Grantor's request, promptly confirm
such fact to the Grantor, in which case the Grantor may consummate the change
referred to in such notice before the end of such 60 day period),

     (b) keep its chief executive office at the address identified in Schedule
3.04, and keep each place of business in the jurisdiction containing its chief
executive office at the address identified in Schedule 3.04, or, in each case,
upon 45 days' written notice to the Collateral Agent (specifically referring to
this Section 4.02), at such other locations in jurisdictions where all actions
referred to in Section 4.04(a) have been competed, and

     (c) maintain its chief executive office in a state of the United States or
the District of Columbia.

     4.03. CERTAIN COVENANTS.

     (a) DELIVERY OF CERTIFICATES AND INSTRUMENTS. All certificates or
instruments at any time representing or evidencing any Collateral shall be
immediately delivered to and held by or on behalf of the Collateral Agent
pursuant hereto, and shall be in suitable form for transfer by delivery, or
shall be accompanied by instruments of transfer or assignment, duly executed in
blank, all in form and substance satisfactory to the Collateral Agent. The
Collateral Agent shall have the right, at any time in its discretion and without
notice to the Grantor, to transfer to or to register in the name of the
Collateral Agent or its nominee any Collateral in registered form (except that
the Collateral Agent shall have such right with respect to capital stock of
Distribution only if an Event of Default has occurred and is continuing). In
addition, the Collateral Agent shall have the right at any time to exchange
certificates or instruments representing or evidencing Collateral for
certificates or instruments of smaller or larger denominations.

     (b) VOTING RIGHTS.

     (i) GENERAL. Subject to Section 4.03(b)(ii), the Grantor shall be entitled
to exercise all voting and other consensual rights pertaining to the Collateral;
provided, that the Grantor shall not exercise or refrain from exercising any
such right if such action would (A) conflict with any provision of this
Agreement or any other Secured Party Document, or (B) in the Grantor's
reasonable judgment, impair the value of any Collateral, or (C) impair the
interest or rights of the Grantor or the Collateral Agent.

     (ii) CERTAIN RIGHTS OF COLLATERAL AGENT. If an Event of Default has
occurred and is continuing, the Collateral Agent may from time to time give
notice to the Grantor revoking in whole or in part the rights of the Grantor
under Section 4.03(b)(i). If and to the extent such notice has been given, and
such Event of Default is continuing, all voting and other consensual rights
pertaining to the Collateral shall thereupon be vested in the Collateral Agent,
who shall have the sole right to exercise or refrain from exercising such
rights.

     (iii) PROXIES, ETC. The Collateral Agent shall execute and deliver to the
Grantor such proxies and other instruments as the Grantor may reasonably request
for the purpose of enabling the Grantor to exercise the voting and other
consensual rights which it is entitled to exercise pursuant to Section
4.03(b)(i). The Grantor hereby grants the Collateral Agent an irrevocable proxy,
with full power of substitution, coupled with an interest, to exercise all
voting and other consensual rights pertaining to the Collateral, exercisable if
and to the extent that the Collateral Agent is entitled to exercise such rights
pursuant to Section 4.03(b)(ii). All third parties are entitled to rely
conclusively on a representation by the Collateral Agent that it is entitled to
exercise such power of attorney.

     (c) DISTRIBUTIONS.

     (i) GENERAL. Subject to Section 4.03(c)(ii), the Grantor shall be entitled
to receive and retain all Distributions that are paid and payable in cash.
Distributions paid or payable other than in cash shall be Collateral, and shall
be forthwith delivered to the Collateral Agent to hold as such.

     (ii) CERTAIN RIGHTS OF COLLATERAL AGENT. If an Event of Default has
occurred and is continuing, all rights of the Grantor to receive and retain the
Distributions that it would otherwise be authorized to receive and retain
pursuant to Section 4.03(c)(i) shall automatically cease, and all such rights
shall thereupon vest in the Collateral Agent. Such Distributions shall be
Collateral, and shall be forthwith delivered to the Collateral Agent and applied
as provided in Section 5.06.



                                     - 6 -
<PAGE>   140




     (iii) PAYMENT OVER. If the Grantor receives any payment or property which
it is not entitled to retain pursuant to Section 4.03(c)(i) or 4.03(c)(ii), such
payment or property shall be received in trust for the benefit of the Collateral
Agent, shall be segregated from other funds and property of the Grantor, and
shall be forthwith delivered to the Collateral Agent as Collateral in the same
form as so received (with any necessary endorsement).

     4.04. FURTHER ASSURANCES.

     (a) GENERAL. The Grantor shall from time to time, at its expense, promptly
execute and deliver all further instruments and agreements, and take all further
actions that may be necessary or appropriate, or that the Collateral Agent may
reasonably request, in order to perfect or protect any assignment, pledge or
security interest granted or purported to be granted hereby or to enable the
Collateral Agent to exercise or enforce its rights and remedies hereunder.

     (b) FOREIGN SUBSIDIARIES. Without limiting the generality of Section
4.04(a), to the extent, if any, that Collateral consists of capital stock or
other equity interests of foreign issuers, the Grantor shall from time to time,
at its expense, promptly execute and deliver such additional or supplementary
security documentation, and all further instruments and agreements, satisfactory
in form and substance to the Collateral Agent, as may be necessary or
appropriate, or that the Collateral Agent may reasonably request, in order to
further grant, perfect or protect any assignment, pledge or security interest
granted or purported to be granted hereby or to enable the Collateral Agent to
exercise or enforce its rights and remedies hereunder, and provide such opinions
of foreign counsel to the Grantor (who shall be reasonably satisfactory to the
Collateral Agent), reasonably satisfactory in form and substance to the
Collateral Agent, as to such matters as the Collateral Agent may reasonably
request.

     (c) FINANCING STATEMENTS, ETC. The Grantor will execute and file such
financing or continuation statements, or amendments thereto, and such other
instruments or notices, as may be necessary or desirable, or as the Collateral
Agent may reasonably request, in order to perfect and preserve the assignment,
pledge or security interest granted or purported to be granted hereby. The
Grantor hereby authorizes the Collateral Agent to file one or more financing or
continuation statements, and amendments thereto, relating to any Collateral
without the signature of the Grantor where permitted by law. A photocopy or
other reproduction of this Agreement or any financing statement covering any
Collateral shall be sufficient as a financing statement where permitted by Law.


                                    ARTICLE V
               CERTAIN RIGHTS AND REMEDIES OF THE SECURED PARTIES

     5.01. COLLATERAL AGENT MAY PERFORM. If the Grantor fails to perform any
obligation under or in connection with this Agreement, the Collateral Agent may
(but shall have no duty to) itself perform or cause performance of such
obligation, and the expenses of the Collateral Agent incurred in connection
therewith shall be payable by the Grantor pursuant to Section 6.04. The
Collateral Agent may from time to time take any other action which the
Collateral Agent deems necessary or appropriate for the maintenance,
preservation or protection of any of the Collateral or of its Lien therein.

     5.02. NO DUTY TO EXERCISE POWERS. The powers of the Collateral Agent under
and in connection with this Agreement are solely to protect its interest in the
Collateral and shall not impose any duty upon it to exercise any such powers.



                                     - 7 -
<PAGE>   141



     5.03. DUTIES OF COLLATERAL AGENT. Except for exercise of reasonable care in
the custody and preservation of any Collateral in its possession and accounting
for moneys received by it pursuant to this Agreement, the Collateral Agent shall
have no duty as to any Collateral. In any event the Collateral Agent (a) shall
have no duty to take any steps to preserve rights against prior parties or any
other rights pertaining to any Collateral, (b) shall have no duty as to
ascertaining or taking action with respect to calls, conversions, exchanges,
tenders, maturities or other matters pertaining to any Collateral, whether or
not the Collateral Agent or any other Secured Party has any knowledge of such
matters, and (c) shall not be liable for any action, omission, insolvency or
default on the part of any agent or custodian (other than the Collateral Agent)
appointed by the Collateral Agent in good faith. The Collateral Agent shall be
deemed to have exercised reasonable care in the custody and preservation of
Collateral in its possession if it accords such Collateral treatment
substantially equivalent to that which the Collateral Agent accords its own
property (but failure to take any such action shall not in itself be deemed a
failure to exercise reasonable care or evidence of such failure). Subject only
to the performance by the Collateral Agent of its duties set forth in this
Section 5.03, risk of loss, damage and diminution in value of the Collateral, of
whatever nature and however caused, shall be on the Grantor.

     5.04. POWER OF ATTORNEY. The Grantor hereby irrevocably appoints the
Collateral Agent, with full power of substitution, to be the attorney-in-fact of
the Grantor, with full authority in the place and stead of the Grantor and in
the name of the Grantor or otherwise, from time to time in the Collateral
Agent's discretion, to take any action and to execute any instruments and
agreements which the Collateral Agent may deem necessary or advisable to
accomplish the purposes of this Agreement, including the following:

          (a) to demand, collect, enforce, file claims for, sue for, recover,
     compromise, release, and take any action or institute any proceedings to
     collect or enforce, all rights to payments due or to become due and all
     other rights of the Grantor under or in connection with any Collateral,

          (b) to receive, endorse and collect any checks, notes or other
     instruments, documents, chattel paper or any other payment media in
     connection with the foregoing clause (a), and

          (c) to perform all obligations of the Grantor hereunder;

provided, however, that except for taking actions referred to in Section 4.04,
such power of attorney may be exercised only so long as an Event of Default has
occurred and is continuing. Such power of attorney is irrevocable and coupled
with an interest. All third parties are entitled to rely conclusively on a
representation by the Collateral Agent that it is entitled to exercise such
power of attorney.

     5.05. CERTAIN REMEDIES. If an Event of Default shall have occurred and be
continuing, the Collateral Agent may exercise all rights and remedies which it
may have under this Agreement, any other agreement, at law or otherwise, and in
addition, the following provisions shall apply:

          (a) The Collateral Agent may exercise all rights and remedies with
     respect to the Collateral and each part thereof as are provided by the UCC
     to a secured party on default (whether or not the UCC applies to the
     affected Collateral). To the extent, if any, the Collateral Agent does not
     otherwise have the right to do so, the Collateral Agent may (i) take
     absolute possession and control of the Collateral or any part thereof, (ii)
     transfer any Collateral into the name of the Collateral Agent or its
     nominees, (iii) notify the parties obligated on the Collateral to make to
     the Collateral Agent any payments due or to become due, (iv) receive any
     payments made under or in connection with the Collateral, (v) exercise all
     rights and remedies of the Grantor under or in connection with the
     Collateral, (vi) demand, collect, enforce, file claims for, 



                                     - 8 -
<PAGE>   142



     sue for, recover, compromise, release, and take any action or institute any
     proceedings to collect or enforce, all rights to payments due or to become
     due and all other rights of the Grantor under or in connection with any
     Collateral, and (vii) otherwise deal in and act with respect to the
     Collateral in all respects as though it were the outright owner thereof;

          (b) All payments received by the Grantor in respect of any Collateral
     shall be received in trust for the benefit of the Secured Parties, shall be
     segregated from other funds of the Grantor and shall be forthwith paid over
     to the Collateral Agent in the same form as so received (with any necessary
     endorsement);

          (c) The Collateral Agent may, without notice except to the extent
     required by Law, sell the Collateral or any part thereof, in one or more
     parcels, at public or private sale, at any of the Collateral Agent's
     offices or elsewhere, for cash, on credit or for future delivery, and upon
     such other terms as the Collateral Agent may deem commercially reasonable.
     The Grantor agrees that, to the extent notice of sale is required by Law,
     at least ten days' notice to the Grantor of the time and place of any
     public sale or the time after which any private sale is to be made, shall
     constitute reasonable notification. The Collateral Agent shall not be
     obligated to make any sale, regardless of notice of sale having been given.
     The Collateral Agent may adjourn any public or private sale from time to
     time by announcement at the time and place fixed therefor, and such sale
     may, without further notice, be made at the time and place to which it was
     so adjourned; and

          (d) The Grantor agrees that the Collateral Agent may comply with any
     limitation or restriction in connection with any sale of any Collateral as
     the Collateral Agent may deem to be necessary or advisable in order to
     comply with any Law, or in order to obtain or make, or avoid the need to
     obtain or make, any approval or registration of the offering, sale or
     purchaser by or with any governmental agency or regulatory body. The
     Grantor agrees that (i) the Collateral Agent may make sales in compliance
     with such limitations and restrictions, even though such sales may be at
     prices and on other terms less favorable to the seller than if such
     approvals or registrations were obtained or made, (ii) the Collateral Agent
     shall have no obligation to delay sale of any Collateral in order to obtain
     or make any such approval or registration, and (iii) it shall not be
     commercially unreasonable to make sales in compliance with such limitations
     and restrictions. Without limiting the generality of the foregoing, the
     Grantor recognizes that the Collateral Agent may be unable, or may deem it
     inadvisable, to effect a public sale of some or all of the Collateral by
     reason of requirements of applicable securities laws, but may deem it
     advisable, for the purpose of complying with such laws, to resort to one or
     more private sales to members of a restricted group of offerees who will be
     obliged, among other things, to acquire such Collateral for their own
     accounts for investment and not with a view to distribution or resale. The
     Grantor agrees that (x) the Collateral Agent may make private sales in such
     manner, even though such sales may be at prices and on other terms less
     favorable to the seller than if such Collateral were sold by public sale,
     (y) the Collateral Agent shall have no obligation to delay sale of any
     Collateral in order to permit the issuers of such Collateral, even if such
     issuers would agree, to register or qualify such Collateral for public sale
     under applicable securities laws, and (z) that it shall not be commercially
     unreasonable to make private sales in such manner.

     5.06. APPLICATION OF PAYMENTS. Except to the extent otherwise provided by
this Agreement or the other Shared Security Documents, all cash held by the
Collateral Agent as Collateral and all cash proceeds received by the Collateral
Agent in respect of any sale of, collection from, or other realization upon any
of the Collateral, shall (after payment of any amounts payable to the Collateral
Agent pursuant to Section 6.04) be deposited in the Collateral Account and
applied as provided in the Collateral Agency Agreement. The Grantor shall remain
liable for any deficiency.

     5.07. REGISTRATION RIGHTS. If the Collateral Agent desires to exercise its
right pursuant to Section 5.05 to sell any Collateral, the Grantor agrees that,
upon request of the Collateral Agent, the Grantor will, at its own expense:

          (a) execute and deliver, and cause each issuer of such Collateral
     contemplated to be sold and the directors and officers thereof to execute
     and deliver, all such instruments and documents, and do or cause to be done
     all such other acts and things, as may be necessary or, in the opinion of
     the Collateral Agent, advisable to register such Collateral under the
     provisions of the Securities Act of 1933, as amended, to cause the
     registration statement relating thereto to become effective and to remain
     effective for such period as prospectuses are required by law to be
     furnished and to make all amendments and supplements thereto and to the
     related prospectus that, in the opinion of the Collateral Agent, are
     necessary or advisable, all in conformity with the requirements of such Act
     and the rules and regulations applicable thereto;

          (b) use its best efforts to qualify such Collateral under the
     securities laws of any state or other jurisdiction and to obtain all
     necessary governmental approvals for the sale of such Collateral, as
     requested by the Collateral Agent;

          (c) cause each such issuer to make available to its security holders,
     as soon as practicable, an earnings statement that will satisfy the
     provisions of Section 11(a) of the Securities Act of 1933, as amended;

          (d) provide the Collateral Agent with such other information and
     projections as may be necessary or, in the opinion of the Collateral Agent,
     advisable to enable the Collateral Agent to effect the sale of such
     Collateral;

          (e) execute and deliver, and cause each such issuer to execute and
     deliver, one or more underwriting agreements in connection with any such
     sale, containing such reasonable terms and provisions (including
     indemnities and contribution provisions for the benefit of the
     underwriters, the Collateral Agent and related Persons) as the Collateral
     Agent may deem necessary or desirable in connection with the sale of such
     Collateral; and

          (f) do or cause to be done all such other acts and things as may be
     necessary to make the sale of such Collateral valid and binding and in
     compliance with applicable law.

     The Collateral Agent is authorized, in connection with any sale of any
     Collateral, to deliver or otherwise disclose to any prospective purchaser
     of such Collateral (i) any registration statement or prospectus, and all
     supplements and amendments thereto, prepared pursuant to clause (a) above,
     (ii) any information and projections provided to it pursuant to clause (d)
     above and (iii) any other information in its possession relating to such
     Collateral.


                                   ARTICLE VI
                                  MISCELLANEOUS

     6.01. AMENDMENTS, ETC. No amendment to or waiver of any provision of this
Agreement, and no consent to any departure by the Grantor herefrom, shall in any
event be effective unless in a writing manually signed by or on behalf of the
Grantor and the Collateral Agent. Any such

specific purpose for which given. Such amendments, waivers and consents shall be
made in accordance with, and shall be subject to, Section 6.01 of the Collateral
Agency Agreement.

     6.02. NO IMPLIED WAIVER; REMEDIES CUMULATIVE. No delay or failure of the
Collateral Agent in exercising any right or remedy under this Agreement shall
operate as a waiver thereof; nor shall any single or partial exercise of any
such right or remedy preclude any other or further exercise thereof or the
exercise of any other right or remedy. The rights and remedies of the Collateral
Agent under this Agreement are cumulative and not exclusive of any other rights
or remedies available hereunder, under any other agreement, at law, or
otherwise.

     6.03. NOTICES. Except to the extent, if any, otherwise expressly provided
herein, all notices and other communications (collectively, "notices") under

     6.04. INDEMNITY AND EXPENSES.

     (a) INDEMNITY. The Grantor agrees to indemnify each Secured Party from and
against any and all claims, losses, liabilities and expenses (including

willful misconduct of a Secured Party.

     (b) EXPENSES. The Grantor will upon demand pay to the Collateral Agent the
amount of all reasonable expenses, including the reasonable fees and expenses of
its counsel and of any experts and agents, which the Collateral Agent may incur

preservation, use or operation of, or the sale of, collection of or other
realization upon, any Collateral, (iii) the exercise or enforcement of any of
the rights of the Collateral Agent hereunder, or (iv) the failure by the Grantor
to perform or observe any of the provisions hereof.

     6.05. ENTIRE AGREEMENT. This Agreement and the other Secured Party
Documents constitute the entire agreement of the parties hereto with respect to
the subject matter hereof and thereof and supersede all prior and
contemporaneous understandings and agreements.

     6.06. SURVIVAL. All representations and warranties of the Grantor contained
in or made in connection with this Agreement shall survive, and shall not be
waived by, the execution and delivery of this Agreement, any investigation by or
knowledge of any Secured Party, any extension of credit, termination of this
Agreement, or any other event or circumstance whatever. The obligations of the
Grantor under Section 6.04 shall survive termination of this Agreement and the

This Agreement has been fully negotiated between the applicable parties, each
party having the benefit of legal counsel, and accordingly neither any doctrine
of construction of security agreements in favor of the secured party, nor any
doctrine of construction of ambiguities against the party controlling the
drafting, shall apply to this Agreement.

     6.09. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
Grantor and its successors and assigns, and shall inure to the benefit of and be
enforceable by the Collateral Agent and the other Secured Parties and their
respective successors and assigns. Without limitation of the foregoing, each
Secured Party (and any successive assignee or transferee) from time to time may
assign or otherwise transfer all or any portion of its rights or obligations
under the Secured Party Documents (including all or any portion of any
commitment to extend credit), or any Obligations, to any other Person, and such
