                  CREDIT AGREEMENT DATED AS OF DECEMBER 7, 1993, AS AMENDED AND
                  RESTATED AS OF AUGUST 26, 1999 (THE "AGREEMENT"), AMONG
                  TRANSTAR, INC., A DELAWARE CORPORATION (THE "BORROWER"), THE
                  LENDERS LISTED IN SECTION 2.01 (THE "LENDERS") AND THE CHASE
                  MANHATTAN BANK, A NEW YORK BANKING CORPORATION ("CHASE"), AS
                  AGENT FOR THE LENDERS (IN SUCH CAPACITY, THE "AGENT") AND AS
                  ISSUING BANK (SUCH TERM, AND THE OTHER CAPITALIZED TERMS USED
                  BUT NOT DEFINED IN THIS PRELIMINARY STATEMENT, BEING USED AS
                  DEFINED IN SECTION 1.01 HEREOF).

         The Borrower, certain Lenders, the Agent and the Issuing Bank are
parties to a Credit Agreement dated as of December 7, 1993, as amended and in
effect prior to the Restatement Closing Date (the "Original Credit Agreement"),
pursuant to which such Lenders (a) made loans on a term basis in an aggregate
principal amount of $445,000,000 on the Original Closing Date and (b) on a
revolving basis committed to make loans in an aggregate principal amount at any
time outstanding not in excess of $25,000,000 at any time and from time to time
prior to the Maturity Date. The Borrower also requested the Issuing Bank to
issue letters of credit for the account of the Borrower.

         The proceeds of Term Borrowings under the Original Credit Agreement
were used by the Borrower (i) to refinance the Borrower's indebtedness, in an
aggregate amount of $255,000,000, in respect of term loans outstanding under the
Existing Credit Agreement, (ii) to redeem at par $179,090,472.48 principal
amount of Subordinated Notes and to pay, in cash, interest accrued on the
outstanding Subordinated Notes for the period from July 1, 1993 through the
Original Closing Date and (iii) to pay a portion of the fees and expenses in
connection with the transactions contemplated thereby with the balance of the
proceeds of such Term Borrowings. The proceeds of Revolving Credit Borrowings
have been and shall continue to be used to provide working capital for the
Borrower and the Subsidiaries.

         The Borrower has requested that the Original Credit Agreement be
amended and restated by this Agreement in order to provide for certain Lenders
to make additional Term Loans to the Borrower in an amount not in excess of
$45,000,000, the proceeds of which will be used (i) to refinance indebtedness in
an aggregate principal amount of $30,000,000, in respect of loans outstanding
under the Short Term Credit Agreement and (ii) to repay Revolving Credit Loans.

         The Lenders, the Agent and the Issuing Bank are willing to amend and
restate the Original Credit Agreement with this

required to reimburse such Lender pursuant to Section 2.13 and (ii) any exercise
of such option shall not affect the obligation of the Borrower to repay such
Loan in accordance with the terms of this Agreement and the applicable Note.
Borrowings of more than one Type may be outstanding at the same time; provided,
however, that the Borrower may not request any Borrowing which, if made, would
result in an aggregate of more than eight separate CD Loans or Eurodollar Loans
of any Lender being outstanding hereunder at any one time. For purposes of the
foregoing, Loans having different Interest Periods, regardless of whether they
commence on the same date, shall be considered separate Loans.

         (c) Each Lender shall make a Loan in the amount of its pro rata
portion, as determined under Section 2.16, of each Borrowing hereunder on the
proposed date thereof by wire transfer of immediately available funds to the
Agent in New York, New York, not later than 1:00 p.m., New York City time,
<PAGE>   40
                                                                              39


and the Agent shall by 2:00 p.m., New York City time, credit the amounts so
received to the general deposit account of the Borrower with the Agent or, if a
Borrowing shall not occur on such date because any condition precedent herein
specified shall not have been met, promptly return the amounts so received to
the respective Lenders in like funds.

         (d) Notwithstanding any other provision of this Agreement, the Borrower
may not request any Revolving Credit Borrowing if the Interest Period requested
with respect thereto would end after the Maturity Date.

         (e) If the Agent has not received from the Borrower the payment
required by Section 3.04(a) by 11:00 a.m., New York City time, on the date on
which the Issuing Bank has notified the Borrower that payment of a draft
presented under any Letter of Credit will be made, as provided in Section
3.04(a), the Agent will promptly notify the Issuing Bank and each Participating
Lender of the Letter of Credit Disbursement and, in the case of each
Participating Lender, its Applicable Percentage of such Letter of Credit
Disbursement. Each Participating Lender will pay to the Agent not later than
2:00 p.m., New York City time, on such date such Participating Lender's
Applicable Percentage of such Letter of Credit Disbursement, which the Agent
will promptly pay to the Issuing Bank. The Agent will promptly remit to each
Participating Lender its Applicable Percentage of any amounts subsequently
received by the Agent from the Borrower in respect of such Letter of Credit
Disbursement.

         SECTION 2.03. Notice of Borrowings. (a) The Borrower shall give the
Agent written or telex notice (or telephone notice promptly confirmed in writing
or by telex) (a) in the case of a Eurodollar Borrowing, not later than 10:00
a.m., New York City time, three Business Days before a proposed Borrowing, (b)
in the case of a CD Borrowing, not later than 10:00 a.m., New York City time,
two Business Days before a proposed Borrowing and (c) in the case of an ABR
Borrowing, not later than 12:00 (noon), New York City time, one Business Day
before a proposed Borrowing. Such notice shall be irrevocable and shall in each
case refer to this Agreement and
<PAGE>   41
                                                                              40


specify (i) whether the Borrowing then being requested is to be a Tranche B Term
Borrowing or a Revolving Credit Borrowing, and whether such Borrowing is to be a
Eurodollar Borrowing, a CD Borrowing or an ABR Borrowing; (ii) the date of such
Borrowing (which shall be a Business Day) and the amount thereof; and (iii) if
such Borrowing is to be a Eurodollar Borrowing or CD Borrowing, the Interest
Period with respect thereto. If no election as to the type of Borrowing is
specified in any such notice, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period with respect to any Eurodollar Borrowing or CD
Borrowing is specified in any such notice, then the Borrower shall be deemed to
have selected an Interest Period of one month's duration, in the case of a
Eurodollar Borrowing, or 30 days' duration, in the case of a CD Borrowing.

         (b) The Agent shall promptly and on the same Business Day, if
practicable, advise the Lenders of any notice given pursuant to this Section
2.03 and of each Lender's portion of the requested Borrowing.

         SECTION 2.04. Notes; Repayment of Loans. The Revolving Credit Loans
made prior to the Restatement Closing Date and Tranche A Term Loans made by each
Lender have been evidenced by Revolving Credit Notes and Tranche A Term Notes,
respectively, duly executed on behalf of the Borrower, dated the Original
Closing Date in substantially the form attached hereto as Exhibit A-1 or A-2,
respectively. The Tranche B Term Loans made by each Lender shall be evidenced by
a Tranche B Term Note duly executed on behalf of the Borrower, dated the
Restatement Closing Date in substantially the form attached hereto as Exhibit
A-3 with the blanks appropriately filled, payable to the order of such Lender in
a principal amount equal to such Lender's Tranche B Term Loan Commitment. The
outstanding principal balance of each Loan, as evidenced by such a Note, shall
be payable (a) in the case of a Revolving Credit Loan, on the Maturity Date and
(b) in the case of a Term Loan, as provided in Section 2.11. Each Note shall
bear interest from the date of the first Borrowing hereunder in respect of such
Note on the outstanding principal balance thereof as set forth in Section 2.06.
Each Lender shall, and is hereby authorized by the Borrower to,
<PAGE>   42
                                                                              41

endorse on the schedule attached to each Note delivered to such Lender (or on a
continuation of such schedule attached to such Note and made a part thereof), or
otherwise to record in such Lender's internal records, an appropriate notation
evidencing the date and amount of each Loan from such Lender, each payment and
prepayment of principal of any such Loan, each payment of interest on any such
Loan and the other information provided for on such schedule, such notations
being rebuttable presumptive evidence of the information recorded thereby;
provided, however, that the failure of any Lender to make such a notation or any
error therein shall not affect the obligation of the Borrower to repay the Loans
made by such Lender in accordance with the terms of this Agreement and the
applicable Notes. Upon written request to the Borrower by a Lender, which
request shall be made through the Agent, the Borrower shall issue to such Lender
a new promissory note in exchange for such Lender's existing Revolving Credit
Note or Term Note, as applicable, which new promissory note shall constitute a
"Note" for all purposes of this Agreement and the other Loan Documents
(evidencing the same Loans) and shall be identical to such existing Note, except
as follows: (a) the phrase in such Note "to the order of" shall be deleted, (b)
the phrase "or registered assigns" shall be inserted immediately before the
phrase "(the "Lender")" in such Note and (c) there shall be inserted in such
Note, as a new paragraph immediately preceding the penultimate paragraph of such
Note, the following two sentences: "This Note is issuable only in registered
form. The holder hereof, by its acceptance of this Note, shall be deemed to have
agreed to transfer this Note only on the terms provided in the Agreement." No
promissory note issued pursuant to the immediately preceding sentence of this
Section 2.04 may be exchanged for a promissory note in a form other than that
provided for in such immediately preceding sentence. Notes that are replaced
with any promissory notes issued pursuant to the second preceding sentence of
this Section 2.04 shall be returned to the Borrower.

         SECTION 2.05. Fees. (a) The Borrower agrees to pay to each
Participating Lender, through the Agent, on the last day of March, June,
September and December in each year, commencing December 31, 1993, and on the
date on which
<PAGE>   43
                                                                              42


the Revolving Credit Commitment of such Participating Lender shall be terminated
as provided herein, a commitment fee (a "Commitment Fee") of 1/2 of 1% per annum
on the average daily unused amount of the Revolving Credit Commitment of such
Participating Lender during the preceding quarter (or shorter period commencing
with the Original Closing Date or ending with the Maturity Date or the date on
which the Revolving Credit Commitment of such Participating Lender shall be
terminated). All Commitment Fees shall be computed on the basis of the actual
number of days elapsed in a year of 360 days. The Commitment Fee due to each
Participating Lender hereunder shall commence to accrue on the Original Closing
Date and shall cease to accrue on the date on which the Revolving Credit
Commitment of such Participating Lender shall be terminated as provided herein.

         (b) The Borrower agrees to pay to the Agent, for its own account and
payment to other Lenders (to the extent applicable), on the Restatement Closing
Date, fees payable in the amounts and at the times separately agreed upon
between the Borrower and the Agent.

         (c) The Borrower agrees to pay to the Agent, for its own account, in
arrears, on the last day of March, June, September and December in each year,
commencing December 31, 1993, an administration fee (the "Agency Fee") in the
amount specified in the letter dated October 28, 1993, between Chase (as
successor to Chemical Bank) and the Borrower. The Borrower agrees to pay to the
Issuing Bank, for its own account, a fronting fee (the "Fronting Fee") in the
amount separately agreed to by the Issuing Bank and the Borrower.

         (d) All Fees shall be paid on the dates due, in immediately available
funds, to the Agent for prompt distribution, if and as appropriate, among the
Lenders. Once paid, none of the Fees shall be refundable under any
circumstances, absent manifest error.

         SECTION 2.06. Interest on Loans. (a) Subject to the provisions of
Section 2.07, each ABR Loan shall bear interest (computed on the basis of the
<PAGE>   44
                                                                              43


actual number of days elapsed over a year of 360 days or, in the event the
Alternate Base Rate is based on the Prime Rate, 365 or 366 days, as the case may
be) at a rate per annum equal to the Alternate Base Rate plus the Applicable
Margin in effect from time to time.

         (b) Subject to the provisions of Section 2.07, each CD Loan shall bear
interest (computed on the basis of the actual number of days elapsed over a year
of 360 days) at a rate per annum, equal to the Adjusted CD Rate for the Interest
Period in effect for such Borrowing plus the Applicable Margin in effect from
time to time.

         (c) Subject to the provisions of Section 2.07, each Eurodollar Loan
shall bear interest (computed on the basis of the actual number of days elapsed
over a year of 360 days) at a rate per annum equal to the Adjusted LIBO Rate for
the Interest Period in effect for such Borrowing plus the Applicable Margin in
effect from time to time.

         (d) Interest on each Loan shall be payable on the Interest Payment
Dates applicable to such Loan except as otherwise provided in this Agreement.
The applicable Alternate Base Rate, Adjusted CD Rate or Adjusted LIBO Rate for
each Interest Period shall be determined by the Agent on the basis of the
information provided to the Agent as provided herein, and such determination
shall be conclusive absent manifest error.

         SECTION 2.07. Default Interest. If the Borrower shall default in the
payment of the principal of or interest on any Loan or any other amount becoming
due hereunder (including any amount due under Section 3.04(a)), by acceleration
or otherwise, the Borrower shall on demand from time to time pay interest, to
the extent permitted by law, on such defaulted amount from the date of such
default up to (but not including) the date of actual payment (after as well as
before judgment) at a rate per annum (computed on the basis of the actual number
of days elapsed over a year of 360 days or, in the event the Alternate Base Rate
is based on the Prime Rate, 365 or 366 days, as the case may be) equal to the
Alternate Base Rate plus the Applicable Margin in respect of ABR Loans plus 2%.

                                                                              44


         SECTION 2.08. Alternate Rate of Interest. (a) In the event, and on each
occasion, that on the day two Business Days prior to the commencement of any
Interest Period for a Eurodollar Borrowing, the Agent shall have determined that
dollar deposits in the principal amounts of the Loans comprising such Borrowing
are not generally available in the London Interbank Market, or that the rates at
which such dollar deposits are being offered will not adequately and fairly
reflect the cost to any Lender of making or maintaining its Eurodollar Loan
during such Interest Period, or that reasonable means do not exist for
ascertaining the Adjusted LIBO Rate, the Agent shall, as soon as practicable
thereafter, give written or telex notice of such determination to the Borrower
and the Lenders. In the event of any such determination, any request by the
Borrower for a Eurodollar Borrowing pursuant to Section 2.03 or Section 2.10
shall, until the Agent shall have advised the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, be deemed to be a
request for an ABR Borrowing. Each determination by the Agent hereunder shall be
conclusive absent manifest error.

         (b) In the event, and on each occasion, that on or before the day on
which the Adjusted CD Rate for a CD Borrowing is to be determined, the Agent
shall have determined that such Adjusted CD Rate cannot be determined for any
reason, including the inability of the Agent to obtain sufficient bids in
accordance with the terms of the definition of Fixed CD Rate, or the Agent shall
determine that the Adjusted CD Rate for such CD Borrowing will not adequately
and fairly reflect the cost to any Lender of making or maintaining its CD Loan
during such Interest Period, the Agent shall, as soon as practicable thereafter,
give written or telex notice of such determination to the Borrower and the
Lenders. In the event of any such determination, any request by the Borrower for
a CD Borrowing pursuant to Section 2.03 or 2.10 shall, until the Agent shall
have advised the Borrower and the Lenders that the circumstances giving rise to
such notice no longer exist, be deemed to be a request for an ABR Borrowing.

determination by the Agent hereunder shall be conclusive absent manifest error.

         SECTION 2.09. Termination and Reduction of Commitments. (a) The
Revolving Credit Commitments and the Letter of Credit Commitment shall be
automatically terminated on the Maturity Date.

         (b) Upon at least three Business Days' prior irrevocable written or
telex notice to the Agent, the Borrower may at any time in whole permanently
terminate, or from time to time in part permanently reduce, the Revolving Credit
Commitments; provided, however, that (i) each partial reduction thereof shall be
in an integral multiple of $1,000,000 and in a minimum principal amount of
$1,000,000 and (ii) the aggregate Revolving Credit Commitments may not be
reduced to an amount which is less than the Letter of Credit Commitment at the
time.

         (c) In the event and on each occasion that a prepayment of Term
Borrowings would be required under Section 2.12(c), (d) or (e) after the Term
Borrowings shall have been fully repaid, then the Revolving Credit Commitments
shall be automatically and permanently reduced at the time and in the amount of
the prepayment that would have been required.

         (d) Each reduction in the Revolving Credit Commitments hereunder shall
be made ratably among the Participating Lenders in accordance with their
respective Revolving Credit Commitments. The Borrower shall pay to the Agent for
the account of the Participating Lenders, on the date of each termination or
reduction in the Revolving Credit Commitments, the Commitment Fees on the amount
of the Revolving Credit Commitments so terminated or reduced accrued through the
date of such termination or reduction.

         SECTION 2.10. Conversion and Continuation of Borrowings. The Borrower
shall have the right at any time upon prior irrevocable notice to the Agent (i)
not later than 12:00 (noon), New York City time, one Business Day prior to
<PAGE>   47
                                                                              46


conversion, to convert any Eurodollar Borrowing or CD Borrowing into an ABR
Borrowing, (ii) not later than 10:00 a.m., New York City time, two Business Days
prior to conversion or continuation, to convert any Eurodollar Borrowing or ABR
Borrowing into a CD Borrowing or to continue any CD Borrowing as a CD Borrowing
for an additional Interest Period, (ii) not later than 10:00 a.m., New York City
time, three Business Days prior to conversion or continuation, to convert any
ABR Borrowing or CD Borrowing into a Eurodollar Borrowing or to continue any
Eurodollar Borrowing as a Eurodollar Borrowing for an additional Interest
Period, (iv) not later than 10:00 a.m., New York City time, three Business Days
prior to conversion, to convert the Interest Period with respect to any
Eurodollar Borrowing to another permissible Interest Period, and (v) not later
than 10:00 a.m., New York City time, two Business Days prior to conversion, to
convert the Interest Period with respect to any CD Borrowing to another
permissible Interest Period, subject in each case to the following:

         (a) each conversion or continuation shall be made pro rata among the
Lenders in accordance with the respective principal amounts of their Loans
comprising the converted or continued Borrowing;

         (b) if less than all the outstanding principal amount of any Borrowing
shall be converted or continued, the aggregate principal amount of such
Borrowing converted or continued shall be an integral multiple of $1,000,000 and
not less than $1,000,000, in the case of ABR Borrowings, and $5,000,000, in the
case of Eurodollar Borrowings or CD Borrowings;

         (c) each conversion shall be effected by each Lender by applying the
proceeds of the new Loan of such Lender resulting from such conversion to the
Loan (or portion thereon of such Lender being converted; accrued interest on a
Loan (or portion thereof) being converted shall be paid by the Borrower at the
time of conversion;

         (d) if any Eurodollar Borrowing or CD Borrowing is converted at a time
other than the end of the Interest Period applicable thereto, the Borrower shall
pay, upon demand, any amounts due to the Lenders pursuant to Section 2.15;
<PAGE>   48
                                                                              47


         (e) any portion of a Borrowing maturing or required to be repaid in
less than one month may not be converted into or continued as a Eurodollar
Borrowing;

         (f) any portion of a Borrowing maturing or required to be repaid in
less than 30 days may not be converted into or continued as a CD Borrowing;

         (g) any portion of a Eurodollar Borrowing or CD Borrowing which cannot
be converted into or continued as a Eurodollar Borrowing or a CD Borrowing by
reason of clause (e) or (f) above shall be automatically converted at the end of
the Interest Period in effect for such Borrowing into an ABR Borrowing; and

         (h) no Interest Period may be selected for any Eurodollar Term
Borrowing or CD Term Borrowing that would end later than a Repayment Date
occurring on or after the first day of such Interest Period if, after giving
effect to such selection, the aggregate outstanding amount of (i) the Eurodollar
Term Borrowings and CD Term Borrowings with Interest Periods ending on or prior
to such Repayment Date and (ii) the ABR Term Borrowings, would not be at least
equal to the principal amount of Term Borrowings of the same class to be paid on
such Repayment Date.

         Each notice pursuant to this Section shall be irrevocable and shall
refer to this Agreement and specify (i) the identity and amount of the Borrowing
that the Borrower requests be converted or continued, (ii) whether such
Borrowing is to be converted to or continued as a Eurodollar Borrowing, a CD
Borrowing or an ABR Borrowing, (iii) if such notice requests a conversion, the
date of such conversion (which shall be a Business Day) and (iv) if such
Borrowing is to be converted to or continued as a Eurodollar Borrowing or CD
Borrowing, the Interest Period with respect thereto. If no Interest Period is
specified in any such notice with respect to any conversion to or continuation
as a Eurodollar Borrowing or CD Borrowing, the Borrower shall be deemed to have
selected an Interest Period of
<PAGE>   49
                                                                              48


one month's duration, in the case of a Eurodollar Borrowing, or 30 days'
duration, in the case of a CD Borrowing. The Agent shall promptly advise the
other Lenders of any notice given pursuant to this Section and of each Lender's
portion of any converted or continued Borrowing. If the Borrower shall not have
given notice in accordance with this Section to continue any Borrowing into a
subsequent Interest Period (and shall not otherwise have given notice in
accordance with this Section to convert such Borrowing), such Borrowing shall,
at the end of the Interest Period applicable thereto (unless repaid pursuant to
the terms hereof), automatically be continued into a new Interest Period as an
ABR Borrowing.

         SECTION 2.11. Repayment of Term Borrowings. (a)(i) The Tranche A Term
Borrowings shall be payable as to principal in 14 consecutive installments
payable on the last day of June and December of each year set forth below,
commencing June 30, 1994 (each such date being called a "Tranche A Repayment
Date"), each such installment on any such date to be in an amount equal to 40%
of the amount set forth below opposite the year during which such date occurs,
in the case of any payment due in June, or 60% of such amount, in the case of
any payment due in December, as such amounts may be reduced from time to time
pursuant to Section 2.11(b):

Year                                Amount
----                                ------

2000                                $67,500,000

         (a)(ii) The Tranche B Term Borrowings shall be payable as to principal
in three consecutive installments payable on each date set forth below (each
such date being called a "Tranche B Repayment Date" and, together with the
Tranche A Repayment Dates, the "Repayment Dates") in the amount set forth
opposite
<PAGE>   50
                                                                              49


such date, as such amounts may be reduced from time to time pursuant to
Section 2.11(b):

Date                                           Amount
----                                           ------

December 31, 1999                              $1,000,000
June 30, 2000                                  $2,000,000
December 31, 2000                              $42,000,000

         (b) (i) Each prepayment of principal of the Term Borrowings of either
class pursuant to Section 2.12(a), Section 2.12(c) (with respect to prepayments
made pursuant to any event described in clause (a) of the definition of
"Prepayment Event" (an "Asset Sale Prepayment Event"), but only up to the
principal amount of $5,000,000 in any fiscal year), or Section 2.12(d) shall be
applied to reduce scheduled payments of principal of such Borrowings due under
this Section 2.11 after the date of such prepayment in the order of maturity;
provided, however, that an aggregate amount equal to the first $5,000,000 of
principal of the Term Borrowings prepaid pursuant to Section 2.12(d) shall be
applied to reduce scheduled payments of principal of such Borrowings due under
this Section 2.11 after the date of such prepayment in the inverse order of
maturity.

         (ii) Each prepayment of principal of the Term Borrowings of either
class pursuant to Section 7.01(g), Section 7.03(b), Section 2.12(c) (except to
the extent prepayments pursuant to Section 2.12(c) are to be applied pursuant to
Section 2.11(b)(i) above), or Section 2.12(e) shall be applied to reduce
scheduled payments of principal of such Borrowings due under this Section 2.11
after the date of such prepayment ratably.

         (iii) The foregoing amortization schedule in clause (a)(i) of this
Section does not reflect any adjustments for prepayments of Tranche A Term
Borrowings made prior to the Restatement Closing Date. It is hereby acknowledged
that all reductions of scheduled principal payments in respect of Tranche A Term
Borrowings that are attributable to prepayments made prior to the Restatement
Closing Date shall be and remain in full force and effect on and after the
Restatement Closing Date.

         (c) To the extent not previously paid, all Term Borrowings shall be due
and payable on the Maturity Date. Each payment of Term Borrowings pursuant to
this Section shall be accompanied by accrued interest on the principal amount
paid to but excluding the date of payment.

         SECTION 2.12. Prepayment. (a) The Borrower shall have the right at any
time and from time to time to prepay any Borrowing, in whole or in part, subject
to the applicable requirements of this Section; provided, however, that each
partial prepayment shall be in an amount which is an integral multiple of
$1,000,000 and not less than $1,000,000. The parties hereto acknowledge that for
purposes of this paragraph (a), the amount of each partial prepayment shall be
determined prior to any allocation of such prepayment.

         (b) On the date of any termination or reduction of the Revolving Credit
Commitments pursuant to Section 2.09, the Borrower shall pay or prepay so much
of the Revolving Credit Borrowings as shall be necessary in order that the
aggregate principal amount of the Revolving Credit Loans outstanding will not
exceed (i) the aggregate Revolving Credit Commitments, after giving effect to
such termination or reduction, minus (ii) the Letter of Credit Exposure at the
time.

         (c) (i) In the event and on each occasion after the Original Closing
Date that a Prepayment Event (other than an Asset Sale Prepayment Event
described in paragraph (c)(ii) below) occurs, the Borrower shall, substantially
simultaneously with (and in any event not later than the Business Day next
following) the occurrence of such Prepayment Event, subject to the provisions of
paragraph (c)(iii) below, apply 100% of the amount of Net Proceeds of such
Prepayment Event to prepay the principal of Term Borrowings as set forth in
paragraph (c)(iii).

         (ii) In the event and on each occasion after the Original Closing Date
that (x) a Prepayment Event which is an Asset Sale Prepayment Event occurs the
Net Proceeds in respect of which
<PAGE>   52
                                                                              51


are less than $1,000,000, and (y) the aggregate amount of the Net Proceeds of
such Prepayment Event and all other such Prepayments Events occurring since the
last prepayment pursuant to this clause is at least $1,000,000, the Borrower
shall, substantially simultaneously with (and in any event not later than the
Business Day next following) receipt by or on behalf of the Borrower or any
Subsidiary thereof of the Net Proceeds in cash from such Prepayment Event,
subject to the provisions of paragraph (c)(iii) below, apply 100% of the
aggregate amount of Net Proceeds of all such Prepayment Events to prepay the
principal of Term Borrowings as set forth in paragraph (c)(iii).

         (iii) Each mandatory prepayment of Term Borrowings after the
Restatement Closing Date pursuant to paragraph (c)(i) or (c)(ii) above or
(c)(iv) below shall be allocated between the Tranche A Term Borrowings and
Tranche B Term Borrowings as provided in Section 2.12(g) below. The Net Proceeds
to be applied to prepay Term Borrowings of either class in accordance with
paragraph (c)(i) or (c)(ii) above (and amounts to be applied to prepay Term
Borrowings of either class in accordance with paragraph (c)(iv) below) shall
first be applied to prepay any outstanding ABR Term Borrowings of such class.
Net Proceeds (or such other amounts) remaining to be applied to the prepayment
of such Term Borrowings shall, at the option of the Borrower, be applied to
prepay Term Borrowings of such class immediately or be deposited in the
Prepayment Account established by the Agent. The Agent shall apply the cash
deposited in the Prepayment Account to prepay Eurodollar Term Borrowings or CD
Term Borrowings of the applicable class on the last day of their respective
Interest Periods (or, at the direction of the Borrower, so long as no Event of
Default has occurred and is continuing, on any earlier date) until all
outstanding Term Borrowings of the applicable class have been prepaid or until
all of the cash on deposit has been exhausted. For purposes of this Agreement,
"Prepayment Account" shall mean an account established by the Borrower with the
Agent and over which the Agent shall have exclusive dominion and control,
including the exclusive right of withdrawal, except that (unless an Event of
Default has occurred and is continuing) the Borrower shall have the exclusive
right to direct the Agent as
<PAGE>   53
                                                                              52

to the investment of such deposits in the Prepayment Account in Permitted
Investments maturing prior to the last day of the applicable Interest Periods of
the Term Borrowings to be prepaid; provided, however, that the Agent shall not
be required to make any investment that, in its sole judgment, would require or
cause the Agent to be, or would result, in any violation of any law, statute,
rule or regulation. The Borrower shall indemnify the Agent for any losses
relating to the investments so that the amount available to prepay Term
Borrowings of the applicable class on the last day of the applicable Interest
Periods is not less than the amount which would have been available had no
investments been made pursuant thereto. Other than any interest earned on such
investments, the Prepayment Account shall not bear interest. Interest or
profits, if any, on such investments shall be payable to the Borrower in arrears
or credited against interest obligations of the Borrower hereunder, at the
option of the Borrower, within five Business Days after the cash on deposit has
been fully applied to prepay such Term Borrowings. If the maturity of the Loans
has been accelerated pursuant to Article VIII, the Agent may, in its sole
discretion, apply all amounts on deposit in the Prepayment Account to satisfy
any of the Obligations.

         (iv) In the event that the calculation of the Net Proceeds relating to
any Prepayment Event included an estimate for income taxes which was at least
$25,000 greater than the income taxes actually payable in respect thereof, the
Borrower shall, promptly after determining the amount of income taxes actually
payable, subject to paragraph (c)(iii) above, apply the amount by which such
estimate exceeded the amount of taxes actually payable to prepay the principal
of Term Borrowings.

         (d) Not later than 90 days after the end of each fiscal year of the
Borrower, commencing with the fiscal year ending December 31, 1994, the Borrower
shall calculate Excess Cash Flow for such fiscal year and apply an amount equal
to 100% of Excess Cash Flow for such fiscal year to prepay the principal of any
outstanding Term Borrowings. Each mandatory prepayment of Term Borrowings after
the Restatement Closing Date pursuant to this paragraph (d) shall be allocated
between the Tranche A Term Borrowings and Tranche B Term Borrowings as provided
in
<PAGE>   54
                                                                              53


Section 2.12(g) below. Not later than the date on which the Borrower is required
to deliver to the Agent financial statements with respect to the end of each
fiscal year pursuant to Section 6.04(a), the Borrower will deliver to the Agent
a certificate signed by any Financial Officer of the Borrower setting forth the
amount, if any, of Excess Cash Flow for such fiscal year and the calculation
thereof in reasonable detail.

         (e) Any amount received by the Agent or any of the Lenders pursuant to
the subordination provisions of any Indebtedness of the Borrower or any
Subsidiary which is subordinate in any respect to the Loans or the Notes shall
(after the application thereof to pay all costs and expenses of the Agent in
connection with the collection thereof) be immediately applied to prepay the
principal of any outstanding Term Borrowings and, if the maturity of the Loans
shall have been accelerated, Revolving Credit Borrowings, ratably.

         (f) Except as expressly provided in this Section, payments with respect
to any paragraph of this Section are in addition to payments made or required to
be made under any other paragraph of this Section.

         (g) Not later than three Business Days (other than in the case of
paragraph (e) of this Section) prior to any prepayment pursuant to this Section,
whether voluntary or otherwise, the Borrower shall give the Agent written or
telex notice (or telephone notice promptly confirmed by written or telex notice)
of such prepayment. The Agent shall promptly and on the same Business Day, if
practicable, advise the Lenders of any notice received by it from the Borrower
pursuant to this Section 2.12. Each notice of prepayment shall specify the
prepayment date and the principal amount of each Borrowing (or portion thereof)
to be prepaid, shall be irrevocable and shall commit the Borrower to prepay such
Borrowing (or portion thereof) by the amount stated therein on the date stated
therein. Each prepayment of Term Borrowings pursuant to this Section after the
Restatement Closing Date shall be allocated (i) in the case of any voluntary
prepayment pursuant to paragraph (a) of this Section, between the Tranche A Term
Borrowings and Tranche B Term Borrowings pro rata based on the remaining
scheduled
<PAGE>   55
                                                                              54


principal payments of such Term Borrowings that will be reduced as a result of
such prepayment pursuant to Section 2.11(b) provided, however, if any prepayment
allocated pursuant to this clause (i) would result in the allocation of less
than $1,000,000 to either Tranche A Term Borrowings or Tranche B Term Borrowings
then the entire amount of such prepayment shall be allocated to the tranche that
would have received the larger allocation, determined in the absence of the
application of this proviso, of such prepayment, or (ii) in the case of all
other prepayments of Term Borrowings, pro rata based on the aggregate
outstanding principal amount of Tranche A Term Borrowings and Tranche B Term
Borrowings, respectively. Each notice of prepayment of Term Borrowings shall
specify the Borrowings to be repaid in accordance with the preceding sentence.
All prepayments under this Section shall be subject to Section 2.15 but
otherwise shall be without premium or penalty. All prepayments under this
Section shall be accompanied by accrued interest on the principal amount being
prepaid to but excluding the date of payment. All prepayments of Term Borrowings
under this Section shall be applied to reduce scheduled payments of principal of
such Term Borrowings due under Section 2.11(a) as provided in Section 2.11(b).

         SECTION 2.13. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision herein, if after December 7, 1993 any change
in applicable law or regulation or in the interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof (whether or not having the force of law) shall change the
basis of taxation of payments to any Lender or the Issuing Bank in respect of
any Letter of Credit or of the principal of or interest on any Eurodollar Loan
or CD Loan made by such Lender or any fees or other amounts payable hereunder
(other than taxes imposed on or measured by the overall net income of such
Lender by the jurisdiction in which such Lender has its principal office (or
lending office) or by any political subdivision or taxing authority therein), or
shall impose, modify or deem applicable any reserve, special deposit or similar
requirement against assets of, deposits with or for the account of or credit
<PAGE>   56
                                                                              55


extended by such Lender (except any such reserve requirement which is reflected
in the Adjusted LIBO Rate or the Adjusted CD Rate) or the Issuing Bank or shall
impose on such Lender or the Issuing Bank or the London Interbank Market any
other condition affecting this Agreement or any Letter of Credit or the Letter
of Credit Exposure or Eurodollar Loans or CD Loans made by such Lender, and the
result of any of the foregoing shall be to increase the cost to such Lender or
the Issuing Bank of making or maintaining the Letter of Credit Exposure, any
Eurodollar Loan or CD Loan (or, in the case of the Issuing Bank, of making any
payment or maintaining the Letter of Credit Commitment) or to reduce the amount
of any sum received or receivable by such Lender or the Issuing Bank hereunder
(whether of principal, interest or otherwise) in respect thereof by an amount
deemed by such Lender or the Issuing Bank to be material, then the Borrower will
pay to such Lender or the Issuing Bank such additional amount or amounts as will
compensate such Lender or the Issuing Bank for such additional costs incurred or
reduction suffered. Each Lender will use all reasonable efforts to designate a
lending office (or a different lending office), so long as such designation is
not adverse to such Lender in such Lender's sole judgment, if such designation
would avoid the need to, or reduce the amount which would otherwise be required
to, compensate such Lender for any additional costs incurred or reduction
suffered.

         (b) If any Lender or the Issuing Bank shall have determined that the
applicability of any law, rule, regulation or guideline adopted pursuant to or
arising out of the July 1988 report of the Basic Committee on Banking
Regulations and Supervisory Practices entitled "International Convergence of
Capital Measurement and Capital Standards", or the adoption after December 7,
1993, of any other law, rule, regulation or guideline regarding capital
adequacy, or any change in any of the foregoing or in the interpretation or
administration of any of the foregoing by any Governmental Authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by any Lender (or any lending office of such Lender) or
the Issuing Bank or any Lender's or the Issuing Bank's holding company with any
request or directive regarding capital adequacy (whether or not having
<PAGE>   57
                                                                              56


the force of law) of any such authority, central bank or comparable agency, has
or would have the effect of reducing the rate of return on such Lender's or the
Issuing Bank's capital or on the capital of such Lender's or the Issuing Bank's
holding company, if any, as a consequence of its obligations hereunder to a
level below that which such Lender or the Issuing Bank or such Lender's or the
Issuing Bank's holding company could have achieved but for such adoption, change
or compliance (taking into consideration such Lender's or the Issuing Bank's
policies and the policies of such Lender's or the Issuing Bank's holding company
with respect to capital adequacy) by an amount deemed by such Lender or the
Issuing Bank to be material, then from time to time the Borrower shall pay to
such Lender or the Issuing Bank such additional amount or amounts as will
compensate such Lender or the Issuing Bank or such Lender's or the Issuing
Bank's holding company for any such reduction suffered.

         (c) A certificate of each Lender or the Issuing Bank setting forth such
amount or amounts as shall be necessary to compensate such Lender or the Issuing
Bank or its holding company as specified in paragraph (a) or (b) above, as the
case may be, shall be delivered to the Borrower and shall be conclusive absent
manifest error. The Borrower shall pay each Lender or the Issuing Bank the
amount shown as due on any such certificate delivered by it within 10 Business
Days after its receipt of the same.

         (d) In the event any Lender or the Issuing Bank delivers a certificate
pursuant to paragraph (c) above, the Borrower may require, at its expense, such
Lender or the Issuing Bank to assign, at par, without recourse (in accordance
with Section 10.04) all its interests, rights and obligations hereunder
(including, in the case of a Lender, all of its Commitment and the Loans at the
time owing to it and the Notes and participations in Letters of Credit held by
it) to a financial institution specified by the Borrower (a "Substitute
Lender"), provided that (i) such assignment shall not conflict with or violate
any law, rule or regulation or order of any court or other Governmental
Authority, (ii) the Borrower shall have received the written consent of the
Agent and the Issuing Bank
<PAGE>   58
                                                                              57


(other than in the case of an assignment by the Issuing Bank), which consent
shall not unreasonably be withheld, to such assignment and (iii) the Borrower
shall have paid to the assigning Lender or the Issuing Bank, as applicable, all
monies accrued and owing hereunder to it (including pursuant to this Section).

         (e) Promptly after any Lender or the Issuing Bank becomes aware of any
circumstance which will, in its sole judgment, result in a request for increased
compensation pursuant to this Section, such Lender or the Issuing Bank shall
notify the Borrower thereof. Failure on the part of any Lender or the Issuing
Bank so to notify the Borrower or to demand compensation for any increased costs
or reduction in amounts received or receivable or reduction in return on capital
with respect to any period shall not constitute a waiver of such Lender's or the
Issuing Bank's right to demand compensation with respect to such period or any
other period. The protection of this Section shall be available to each Lender
and the Issuing Bank regardless of any possible contention of the invalidity or
inapplicability of the law, rule, regulation, guideline or other change or
condition which shall have occurred or been imposed.

         SECTION 2.14. Change in Legality. (a) Notwithstanding any other
provision herein, if any change in any law or regulation or in the
interpretation thereof by any Governmental Authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations as
contemplated hereby with respect to any Eurodollar Loan, then, by written notice
to the Borrower and to the Agent, such Lender may:

                  (i) declare that Eurodollar Loans will not thereafter be made
         by such Lender hereunder, whereupon any request by the Borrower for a
         Eurodollar Borrowing shall, as to such Lender only, be deemed a request
         for an ABR Loan unless such declaration is subsequently withdrawn; and
<PAGE>   59
                                                                              58


                  (ii) require that all outstanding Eurodollar Loans made by it
         be converted to ABR Loans, in which event all such Eurodollar Loans
         shall be automatically converted to ABR Loans as of the effective date
         of such notice as provided in paragraph (b) below.

In the event any Lender shall exercise its rights under (i) or (ii) above, all
payments and prepayments of principal which would otherwise have been applied to
repay the Eurodollar Loans that would have been made by such Lender or the
converted Eurodollar Loans of such Lender shall instead be applied to repay the
ABR Loans made by such Lender in lieu of, or resulting from the conversion of,
such Eurodollar Loans.

         (b) For purposes of this Section, a notice to the Borrower by any
Lender shall be effective, if lawful, on the last day of the then current
Interest Period; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         (c) In the event any Lender gives a notice pursuant to paragraph (a)
above, the Borrower may require, at its expense, such Lender to assign, at par,
without recourse (in accordance with Section 10.04) all its interests, rights
and obligations hereunder (including all of its Commitment and the Loans at the
time owing to it and the Notes and participations in Letters of Credit held by
it) to a Substitute Lender, provided that (i) such assignment shall not conflict
with or violate any law, rule or regulation or order of any court or other
Governmental Authority, (ii) the Borrower shall have received the written
consent of the Agent and the Issuing Bank, which consent shall not unreasonably
be withheld, to such assignment and (iii) the Borrower shall have paid to the
assigning Lender all monies accrued and owing hereunder to it.

         SECTION 2.15. Indemnity. The Borrower shall indemnify each Lender
against any loss or reasonable expense which such Lender may sustain or incur as
a consequence of (a) any failure by the Borrower to fulfill on the date of any
borrowing hereunder the applicable conditions set forth in Article V, so long as
any such failure is not solely due to the failure of the Agent or any Lender to
comply
<PAGE>   60
                                                                              59


with its obligations hereunder in all material respects, (b) any failure by the
Borrower to borrow or to refinance, convert or continue any Loan hereunder after
irrevocable notice of such borrowing, refinancing, conversion or continuation
has been given pursuant to Section 2.03 or 2.10, so long as any such failure is
not solely due to the failure of the Agent or any Lender to comply with its
obligations hereunder in all material respects, (c) any payment, prepayment or
conversion of a Eurodollar Loan or CD Loan, whether voluntary or involuntary,
pursuant to any other provision of this Agreement (including pursuant to Section
2.13(d), 2.14(c) or 2.18(e)) or otherwise made on a date other than the last day
of the Interest Period applicable thereto, so long as any such payment,
prepayment or conversion is not solely due to the failure of the Agent or any
Lender to comply with its obligations hereunder in all material respects, (d)
any default in payment or prepayment of the principal amount of any Loan or any
part thereof or interest accrued thereon, as and when due and payable (at the
due date thereof, by irrevocable notice of prepayment or otherwise) or (e) the
occurrence of any Event of Default, including, in each such case, any loss or
reasonable expense sustained or incurred or to be sustained or incurred in
liquidating or employing deposits from third parties acquired to effect or
maintain such Loan or any part thereof as a Eurodollar Loan or CD Loan. Such
loss or reasonable expense shall include an amount equal to the excess, if any,
as reasonably determined by such Lender, of (i) its cost of obtaining the funds
for the Loan being paid, prepaid, converted or not borrowed (based on the
Adjusted LIBO Rate or Adjusted CD Rate applicable thereto), for the period from
the date of such payment, prepayment, conversion or failure to borrow, convert
or continue to the last day of the Interest Period for such Loan (or, in the
case of a failure to borrow, the Interest Period for such Loan which would have
commenced on the date of such failure to borrow, convert or continue) over (ii)
the amount of interest (as reasonably determined by such Lender) that would be
realized by such Lender in reemploying the funds so paid, prepaid, converted or
not borrowed, converted or continued for such period or Interest Period, as the
case may be. A certificate of any Lender setting forth any amount or amounts
which such Lender is entitled to receive pursuant to this Section shall be
delivered to the Borrower and shall be conclusive absent manifest error.

                                                                              60


         SECTION 2.16. Pro Rata Treatment. Except as required under Section
2.14, each Borrowing, each payment or prepayment of principal of any Borrowing,
each payment of interest on the Loans, each payment of the Commitment Fee and
the Letter of Credit Fee, each reduction of the Revolving Credit Commitments and
each continuation or conversion of any Borrowing shall be allocated pro rata
among the Lenders in accordance with their respective applicable Commitments
(or, if such Commitments shall have expired or been terminated, in accordance
with the respective principal amounts of their applicable Loans outstanding).
Each Lender agrees that in computing such Lender's portion of any Borrowing to
be made hereunder, the Agent may, in its discretion, round each Lender's
percentage of such Borrowing, computed in accordance with Section 2.01, to the
next higher or lower whole dollar amount.

         SECTION 2.17. Sharing of Setoffs. Each Lender agrees that if it shall,
through the exercise of a right of banker's lien, setoff or counterclaim against
the Borrower, or pursuant to a secured claim under Section 506 of Title 11 of
the United States Code or other security or interest arising from, or in lieu
of, such secured claim, received by such Lender under any applicable bankruptcy,
insolvency or other similar law or otherwise, or by any other means, obtain
payment (voluntary or involuntary) in respect of any Loan or any Letter of
Credit Disbursement as a result of which the unpaid principal portion of its
Loans and the unpaid amount of its Letter of Credit participations shall be
proportionately less than the unpaid principal portion of the Loans and unpaid
amount of the Letter of Credit participations of any other Lender, it shall
simultaneously purchase from such other Lender at face value a participation in
the Loans or Letter of Credit participations of such other Lender, so that the
aggregate unpaid principal amount of the Loans and participations in Loans and
the unpaid amount of Letter of Credit participations and participations in
Letter of Credit participations held by each Lender shall be in the same
proportion to the aggregate unpaid principal amount of all
<PAGE>   62
                                                                              61


Loans then outstanding and the aggregate unpaid amount of all Letter of
Credit Disbursements as the principal amount of its Loans and the unpaid amount
of its Letter of Credit participations prior to such exercise of banker's lien,
setoff or counterclaim or other event was to the principal amount of all Loans
outstanding and the aggregate unpaid amount of all Letter of Credit
Disbursements prior to such exercise of banker's lien, setoff or counterclaim or
other event; provided, however, that, if any such purchase or purchases or
adjustments shall be made pursuant to this Section and the payment giving rise
thereto shall thereafter be recovered, such purchase or purchases or adjustments
shall be rescinded to the extent of such recovery and the purchase price or
prices or adjustment restored without interest. The Borrower expressly consents
to the foregoing arrangements and agrees that any Lender holding a participation
in a Loan or Letter of Credit participation deemed to have been so purchased may
exercise any and all rights of banker's lien, setoff or counterclaim with
respect to any and all moneys owing by the Borrower to such Lender by reason
thereof as fully as if such Lender had made a Loan directly to the Borrower in
the amount of such participation or as if such Lender had made a Letter of
Credit Disbursement in the amount of such participation.

         SECTION 2.18. Taxes. (a) Except as otherwise required by law, any and
all payments by the Borrower hereunder shall be made, in accordance with Section
2.19, free and clear of and without deduction or withholding for any and all
present or future taxes, levies, imposts, deductions, charges or withholdings,
and all liabilities with respect thereto, excluding:

                  (i) in the case of the Agent or the Issuing Bank, taxes
         imposed on its income or net worth, and franchise taxes imposed on it,
         by the jurisdiction under the laws of which it is organized or any
         political subdivision thereof, and

                  (ii) in the case of each Lender, taxes imposed on its income
         or net worth, and franchise taxes imposed on it, by the jurisdiction of
         its principal office or lending office
<PAGE>   63
                                                                              62


         or any political subdivision thereof, and withholding taxes payable
         with respect to payments to such Lender at its principal office or
         lending office under laws (including any treaty, ruling, determination
         or regulation) in effect on the date hereof, but not any increase in
         withholding tax resulting from any subsequent change in such laws,

(all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as "Taxes"). If the Borrower shall
be required by law to deduct any Taxes from or in respect of any sum payable
hereunder to any Lender, the Agent or the Issuing Bank, (i) the sum payable
shall be increased by the amount necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section) such Lender, the Agent or the Issuing Bank (as the case may be)
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. Each Lender will use all
reasonable efforts to designate a lending office (or a different lending
office), so long as such designation is not adverse to such Lender in such
Lender's sole judgment, if such designation would avoid the need to, or reduce
the amount which would otherwise be required to, increase the amounts by which
the sums payable hereunder shall be increased pursuant to this paragraph.

         Notwithstanding the foregoing, the Borrower shall not be liable for any
Taxes due in the following circumstances:

         (x) if a Lender that is not a U.S. person shall have delivered Internal
Revenue Service Form W-8ECI (or any successor form) to the Borrower pursuant to
Section 2.18(b) and either (i) such Lender ceases to be exempt from deduction or
withholding of Tax imposed by the United States ("United States Tax") in respect
of payments to it hereunder for a reason that is not related to a change in
United States federal income tax law, regulation or official interpretation
occurring after the

date hereof (a "Relevant Change in Law") and such Lender has not timely provided
to the Borrower a valid and complete, signed copy of either (x) Internal Revenue
Service Form W-8BEN (with respect to the benefits of any income tax treaty) (or
any successor form) indicating its exemption from or entitlement to a reduced
rate of withholding pursuant to an income tax treaty or (y) Internal Revenue
Service Form W-8BEN (with respect to the portfolio exemption) and a Section
2.18(b) Certificate (as defined in Section 2.18(b) hereof) indicating its
exemption from withholding taxes or (ii) if, as the result of a Relevant Change
in Law regarding withholding vis-a-vis effectively connected income, such Lender
is taxed on payments made pursuant to this Agreement on both a net income basis
and by way of deduction or withholding and the amounts withheld or deducted with
respect to such payments are fully creditable against such net income tax
assessed with respect to such payments;

         (y) if a Lender that is not a U.S. person shall have delivered Internal
Revenue Service Form W-8BEN (with respect to a complete exemption under an
income tax treaty) (or any successor form) to the Borrower pursuant to Section
2.18(b) and such Lender becomes subject to Tax at an increased rate in respect
of payments to it hereunder for a reason that is not related to a Relevant
Change in Law, or to an amendment, modification or revocation of an applicable
tax treaty or a change in official position regarding the application or
interpretation thereof, in each case occurring after the date hereof (a
"Relevant Change in Tax Treaty") and such Lender has not timely provided to the
Borrower a valid and complete, signed copy of either (x) Internal Revenue
Service Form W-8ECI (or any successor form) indicating its exemption from
withholding taxes or (y) Internal Revenue Service Form W-8BEN (with respect to
the portfolio exemption) and a Section 2.18(b) Certificate (as defined in
Section 2.18(b) hereof) indicating its exemption from withholding taxes;

         (yy) if a Lender that is not a U.S. Person shall have delivered
Internal Revenue Service Form W-8BEN (with respect to the portfolio exemption)
and a Section 2.18(b) Certificate (as defined in Section 2.18(b) hereof) (or any
successor forms) to
<PAGE>   65
                                                                              64


the Borrower pursuant to Section 2.18(b) and such Lender becomes subject to tax
at an increased rate in respect of payments to it hereunder for a reason that is
not related to a Relevant Change in Law and such Lender has not timely provided
to Borrower a valid and complete, signed copy of Internal Revenue Service Form
W-8BEN (with respect to the benefits of any income tax treaty) (or any successor
form) indicating its exemption or entitlement to a reduced rate of withholding
pursuant to an income tax treaty or Internal Revenue Service Form W-8ECI (or any
successor form) indicating its exemption from withholding taxes; or

         (z) if a Lender that is not a U.S. person shall fail to comply with its
obligations, if any, under Section 2.18(b).

         For purposes of Section 2.18(a)(x)(i), Section 2.18(a)(y) and Section
2.18(a)(yy), the fact that a Lender ceases to be exempt from deduction or
withholding of United States Tax will be related to a Relevant Change in Law or
Relevant Change in Tax Treaty if and only if such Lender would not have ceased
to be so exempt but for such Relevant Change in Law or Relevant Change in Tax
Treaty.

         If a Lender provides a Form W-8BEN (with respect to the benefits of any
income tax treaty) indicating that it is entitled to a reduction in the rate of,
but not a complete exemption from, U.S. withholding tax, the Borrower shall
withhold at such reduced rate and shall have no indemnity or other obligation to
such Lender pursuant to this Section with respect to United States Taxes imposed
at the current rate of U.S. withholding tax applicable to such Lender pursuant
to U.S. tax laws and the applicable tax treaty (the "Current Rate").

         If any Lender that is not a U.S. person is not, as of the Restatement
Closing Date or as of the effective date of the Assignment and Acceptance in the
case of an assignee Lender, legally eligible to provide a valid and complete
signed copy of Internal Revenue Service Form W-8BEN (with respect to a complete
exemption under an income tax treaty), Internal Revenue Service Form W-8ECI or
Internal Revenue Service Form W-8BEN (with respect to the portfolio exemption)
and a Section

                                                                              65


2.18(b) Certificate (as defined in Section 2.18(b) hereof) with respect to
payments to be made hereunder, the Borrower shall withhold from payments to such
Lender the appropriate amount of U.S. withholding taxes and shall have no
indemnity or other obligations to such Lender pursuant to this Section with
respect to U.S. Taxes imposed at the Current Rate applicable to such Lender.

         (b) Each Lender that is not a U.S. person and that is legally able to
do so severally covenants and agrees to deliver to the Borrower, on or before
the date of the signing of this Agreement (or on or before the effective date of
the Assignment and Acceptance relating to an assignee Lender) and (i) within 30
days prior to the date on which, through lapse of time, a previously provided
Internal Revenue Service Form W-8BEN (with respect to the benefits of an income
tax treaty) becomes no longer effective, an accurate and complete signed copy of
Internal Revenue Service Form W-8BEN (with respect to the benefits of an income
tax treaty) (or any successor form), dated the date hereof or such later date,
as appropriate, or (ii) within 30 days prior to the beginning of each subsequent
taxable year of such Lender so long as any Loan is outstanding, two accurate and
complete signed copies of Internal Revenue Service Form W-8ECI (or any successor
form), dated the date hereof or any such subsequent date, as appropriate, (iii)
or within 30 days prior to the date on which, through lapse of time, a
previously provided Internal Revenue Service Form W-8BEN (with respect to the
portfolio exemption) becomes no longer effective, two accurate and complete
signed copies of Internal Revenue Service Form W-8BEN (with respect to the
portfolio exemption) and a Section 2.18(b) Certificate (as defined in this
Section 2.18(b) (or any successor form), dated as appropriate and, in each case,
such other related forms (including any certificate with respect thereto) as the
Borrower may reasonably request and that are required pursuant to the Code or
the Regulations or any administrative rulings or procedures thereunder. In
addition, each such Lender shall deliver to the Borrower an accurate and
complete signed copy of Internal Revenue Service Form W-8BEN (with respect to
the benefits of an income tax treaty), two accurate and complete signed copies
of Internal Revenue Service Form W-8ECI or two
<PAGE>   67
                                                                              66


accurate and complete signed copies of Internal Revenue Service Form W-8BEN
(with respect to the portfolio exemption) and, in the case of a Lender that
delivers Form W-8BEN (with respect to the portfolio exemption), a certificate
representing that such Lender is not a bank for purposes of Section 881(c) of
the Code, is not a 10-percent shareholder (within the meaning of Section
871(h)(3)(B) of the Code) of the Borrower and is not a controlled foreign
corporation related to the Borrower (within the meaning of Section 864(d)(4) of
the Code) (a "Section 2.18(b) Certificate") as the case may be, at any time that
a change in circumstances renders the previous form inaccurate in any material
respect.

         Any Lender that is not a U.S. person and that, as of the Restatement
Closing Date or as of the effective date of the Assignment and Acceptance in the
case of an Assignee Lender, is not eligible to provide a valid and complete
signed copy of Internal Revenue Service Form W-8BEN (with respect to a complete
exemption under an income tax treaty), W-8ECI or Internal Revenue Service Form
W-8BEN (with respect to the portfolio exemption) and a Section 2.18(b)
Certificate (as defined in Section 2.18(b) hereof) shall have no obligation
pursuant to Section 2.18(b) to provide such Form.

         (c) In addition, 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 hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement
(hereinafter referred to as "Other Taxes").

         (d) The Borrower will indemnify each Lender, the Issuing Bank and the
Agent for the full amount of Taxes or Other Taxes (including any Taxes or Other
Taxes imposed by any jurisdiction (except as specified in Section 2.18(a)) on
amounts payable under this Section paid by such Lender, the Issuing Bank or the
Agent and any liability (including penalties, interest and expenses) arising
therefrom or with respect thereto, whether or not such Taxes or Other Taxes were
correctly or legally asserted; provided, however, that at the request of the
Borrower and solely at the Borrower's expense such Lender, the
<PAGE>   68
                                                                              67


Issuing Bank or the Agent shall use reasonable efforts to contest the payment of
such Taxes or Other Taxes which the Borrower and the Agent, the Issuing Bank or
such Lender, as applicable, believe were not correctly or legally asserted. This
indemnification shall be made within 30 days from the date such Lender, the
Issuing Bank or the Agent (as the case may be) makes written demand therefor. If
any Lender receives a refund in respect of any Taxes or Other Taxes for which
such Lender has received payment from the Borrower hereunder, such Lender shall,
within 30 days of receipt by such Lender, repay such refund to the Borrower,
provided that the Borrower, upon the request of such Lender, agrees to return
such refund (plus any penalties, interest or other charges) to the Lender in the
event such Lender is required to repay such refund.

         (e) In the event the Borrower is required to increase any amounts
payable to any Lender or the Issuing Bank pursuant to paragraph (a) above
(unless such Lender or the Issuing Bank shall have waived its right thereunder
with respect to any specific increase) or any Lender or the Issuing Bank makes a
written demand for an indemnity in respect of any Taxes pursuant to paragraph
(d) above, the Borrower may require, at its expense, such Lender or the Issuing
Bank to assign, at par, without recourse (in accordance with Section 10.04) all
its interests, rights and obligations hereunder (including, in the case of a
Lender, all of its Commitment and the Loans at the time owing to it and the
Notes and participations in Letters of Credit held by it) to a Substitute
Lender, provided that (i) such assignment shall not conflict with or violate any
law, rule or regulation or order of any court or other Governmental Authority,
(ii) the Borrower shall have received the written consent of the Agent and the
Issuing Bank (other than in the case of an assignment by the Issuing Bank),
which consent shall not unreasonably be withheld, to such assignment and (iii)
the Borrower shall have paid to the assigning Lender or the Issuing Bank, as
applicable, all monies accrued and owing hereunder to it (including pursuant to
this Section).

         (f) The Borrower will, within 30 days after the date of any payment of
Taxes or Other Taxes withheld by the Borrower in respect of any payment to any
Lender, furnish to the Agent the

                                                                              68


original or a certified copy of a receipt evidencing payment thereof.

         (g) Without prejudice to the survival of any other agreement hereunder,
the agreements and obligations contained in this Section shall survive the
payment in full of principal and interest hereunder.

         SECTION 2.19. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any Fees or other
amounts) hereunder and under any other Loan Document not later than 11:00 a.m.,
New York City time, on the date when due in dollars to the Agent at its offices
at 270 Park Avenue, New York, New York, in immediately available funds. The
Agent shall promptly remit in dollars to the Issuing Bank or the Lenders, as the
case may be, their share of any payments received by the Agent.

         (b) Whenever any payment (including principal of or interest on any
Borrowing or any Fees or other amounts) hereunder or under any other Loan
Document shall become due, or otherwise would occur, on a day that is not a
Business Day, such payment may be made on the next succeeding Business Day, and
such extension of time shall in such case be included in the computation of
interest or Fees, if applicable.

                               LETTERS OF CREDIT

         SECTION 3.01. Issuance of Letters of Credit. (a) The Issuing Bank
agrees, upon the terms and subject to the conditions hereinafter set forth, to
issue Letters of Credit, in a form reasonably acceptable to the Agent and the
Issuing Bank, appropriately completed, for the account of the Borrower, at any
time and from time to time on and after the Original Closing Date until the
earlier of the Maturity Date and the termination of the Letter of Credit
Commitment in accordance with the terms hereof; provided, however, that any
Letter of Credit shall be issued by the Issuing Bank only if, and each request
by the Borrower for the issuance of any Letter of Credit shall be deemed a
representation and warranty of the Borrower that, immediately following the
issuance of any such Letter of Credit, (i) the Letter of Credit Exposure shall
not exceed the Letter of Credit Commitment in effect at the time and (ii) the
sum of the Letter of Credit Exposure and the aggregate principal amount of
outstanding Revolving Credit Loans shall not exceed the aggregate Revolving
Credit Commitments at the time.

         (b) Each Letter of Credit shall expire at the close of business on the
Maturity Date, unless such Letter of Credit expires by its terms on an earlier
date. Each Letter of Credit shall provide for payments of drawings in dollars.

         (c) Each issuance of any Letter of Credit shall be made on at least
three Business Days' prior written or telex notice from the Borrower to the
Issuing Bank and the Agent (which shall give prompt notice thereof to each
Participating Lender) specifying the date of issuance, the date on which such
Letter of Credit is to expire (which shall not be later than the earlier of (i)
the Maturity Date and (ii) subject to extension, 180 days, in the case of
documentary or trade Letters of Credit, and one year, in the case of standby
Letters of Credit, after the date of any such Letter of Credit), the amount of
such Letter of Credit, the name and address of the beneficiary
<PAGE>   71
                                                                              70


of such Letter of Credit and such other information as may be necessary or
desirable to complete such Letter of Credit. The Issuing Bank will give the
Agent and each Participating Lender reasonably prompt notice of the issuance and
amount of each Letter of Credit and the expiration of each Letter of Credit.

         SECTION 3.02. Participations; Unconditional Obligations. (a) By the
issuance of a Letter of Credit and without any further action on the part of the
Issuing Bank or the Participating Lenders in respect thereof, the Issuing Bank
hereby grants to each Participating Lender, and each Participating Lender hereby
agrees to acquire from the Issuing Bank, a participation in such Letter of
Credit equal to such Participating Lender's Applicable Percentage of the face
amount of such Letter of Credit, effective upon the issuance of such Letter of
Credit. In consideration and in furtherance of the foregoing, each Participating
Lender hereby absolutely and unconditionally agrees to pay to the Agent, on
behalf of the Issuing Bank, in accordance with Section 2.02(e), such
Participating Lender's Applicable Percentage of each Letter of Credit
Disbursement made by the Issuing Bank; provided, however, that the Participating
Lenders shall not be obligated to make any such payment to the Issuing Bank with
respect to any wrongful payment or disbursement made under any Outstanding
Letter of Credit as a result of the gross negligence or wilful misconduct of the
Issuing Bank.

         (b) Each Participating Lender acknowledges and agrees that its
obligation to acquire participations pursuant to paragraph (a) in respect of
Letters of Credit is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including the occurrence and continuance of an Event of
Default or Potential Event of Default hereunder, and that each such payment
shall be made without any offset, abatement, withholding or reduction
whatsoever.

         SECTION 3.03. Letter of Credit Fee. The Borrower agrees to pay to the
Agent for the account of the Participating Lenders for each calendar quarter (or
shorter period commencing with December 7, 1993, or ending
<PAGE>   72
                                                                              71


with the first date on which the Letter of Credit Commitment shall have expired
or been terminated and there shall be no Outstanding Letters of Credit) a fee
(the "Letter of Credit Fee") on the average daily amount of the Outstanding
Letters of Credit at a rate per annum equal to the Applicable Margin in respect
of Eurodollar Loans in effect from time to time. The Letter of Credit Fee shall
be computed on the basis of the actual number of days elapsed over a year of 360
days. The Agent agrees to disburse to each Participating Lender its pro rata
portion of such Letter of Credit Fee promptly upon receipt. The Letter of Credit
Fee shall be paid in arrears on the last day of March, June, September and
December of each year and on the Maturity Date (or the first date on which the
Letter of Credit Commitment shall have expired or been terminated and there
shall be no Outstanding Letters of Credit, if earlier), commencing on the first
such date following the Original Closing Date. Once paid the Letter of Credit
Fee paid or payable shall not be refundable in any circumstances whatsoever,
absent manifest error.

         SECTION 3.04. Agreement To Repay Letter of Credit Disbursements. (a) If
the Issuing Bank shall pay any draft presented under a Letter of Credit, the
Borrower shall pay to the Agent, on behalf of the Issuing Bank, an amount equal
to the amount of such draft before 11:00 a.m., New York City time, on the
Business Day on which the Issuing Bank shall have notified the Borrower that
payment of such draft will be made (or such later time as is not later than one
hour after the Borrower shall have received such notice or, if the Borrower
shall have received such notice later than 4:00 p.m. on any Business Day, not
later than 10:00 a.m. on the immediately following Business Day). The Agent will
promptly pay any such amounts received by it to the Issuing Bank, unless the
Lenders shall have funded their reimbursement obligations under Section 3.02(a).
<PAGE>   73
                                                                              72


         (b) The Borrower's obligation to repay the Issuing Bank for payments
and disbursements made by the Issuing Bank under the Outstanding Letters of
Credit shall be absolute, unconditional and irrevocable under any and all
circumstances and irrespective of:

                  (i) any lack of validity or enforceability of any Letter of
         Credit;

                  (ii) the existence of any claim, setoff, defense or other
         right which the Borrower or any other person may at any time have
         against the beneficiary under any Letter of Credit, the Issuing Bank,
         the Agent or any Lender (other than the defense of payment in
         accordance with the terms of this Agreement or a defense based on the
         gross negligence or wilful misconduct of the Issuing Bank) or any other
         person in connection with this Agreement or any other agreement or
         transaction;

                  (iii) any draft or other document presented under a 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; provided that payment by the Issuing Bank under such Letter of
         Credit against presentation of such draft or document shall not have
         constituted gross negligence or wilful misconduct of the Issuing Bank;

                  (iv) payment by the Issuing Bank under a Letter of Credit
         against presentation of a draft or other document which does not comply
         with the terms of such Letter of Credit; provided that such payment
         shall not have constituted gross negligence or wilful misconduct of the
         Issuing Bank; and

                  (v) any other circumstance or event whatsoever, whether or not
         similar to any of the foregoing; provided that such other circumstance
         or event shall not have been the result of gross negligence or wilful
         misconduct of the Issuing Bank.
<PAGE>   74
                                                                              73


It is understood that in making any payment under a Letter of Credit (x) the
Issuing Bank's exclusive reliance on the documents presented to it under such
Letter of Credit as to any and all matters set forth therein, including reliance
on the amount of any draft presented under such Letter of Credit, whether or not
the amount due to the beneficiary equals the amount of such draft and whether or
not any document presented pursuant to such Letter of Credit proves to be
insufficient in any respect, if such document on its face appears to be in
order, and whether or not any other statement or any other document presented
pursuant to such Letter of Credit proves to be forged or invalid or any
statement therein proves to be inaccurate or untrue in any respect whatsoever
and (y) any noncompliance in any immaterial respect of the documents presented
under a Letter of Credit with the terms thereof shall, in each case, not be
deemed wilful misconduct or gross negligence of the Issuing Bank.

         SECTION 3.05. Letter of Credit Operations. The Issuing Bank shall,
promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment under an Outstanding Letter of Credit to
ascertain that the same appear on their face to be in substantial conformity
with the terms and conditions of such Outstanding Letter of Credit. The Issuing
Bank shall as promptly as possible, but in no event later than one hour after
such demand for payment, give oral notification, confirmed by tested telex, to
the Agent and the Borrower of such demand for payment and the determination by
the Issuing Bank as to whether such demand for payment was in accordance with
the terms and conditions of such Outstanding Letter of Credit and whether the
Issuing Bank has made or will make a Letter of Credit Disbursement thereunder,
provided that the failure to give such notice shall not relieve the Borrower of
its obligation to reimburse the Issuing Bank with respect to any such Letter of
Credit Disbursement, and the Agent shall promptly give each Lender notice
thereof.

         SECTION 3.06. Cash Collateralization. If any Event of Default shall
occur and be continuing, the Borrower shall on the Business Day it receives
<PAGE>   75
                                                                              74


notice from the Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, Participating Lenders holding participations in
Outstanding Letters of Credit representing more than 50% of the aggregate
undrawn amount of all Outstanding Letters of Credit) therefor, deposit in an
account with the Agent, for the benefit of the Lenders, an amount in cash equal
to the Letter of Credit Exposure as of such date. Such deposit shall be held by
the Agent as collateral for the payment and performance of the Obligations. So
long as such Event of Default is continuing, the Agent shall have exclusive
dominion and control, including the exclusive right of withdrawal, over such
account. Other than any interest earned on the investment of such deposits in
Permitted Investments, which investments shall be made at the option and sole
discretion of the Agent, such deposits shall not bear interest. Interest or
profits, if any, on such investments shall accumulate in such account. Moneys in
such account shall automatically be applied by the Agent to reimburse the
Issuing Bank for Letter of Credit Disbursements and, if the maturity of the
Loans has been accelerated (but subject to the consent of Participating Lenders
holding participations in Outstanding Letters of Credit representing more than
50% of the aggregate undrawn amount of all Outstanding Letters of Credit), to
satisfy the Obligations. All remaining amounts on deposit shall be returned to
the Borrower within three Business Days after all Events of Default have been
cured or waived.

         SECTION 3.07. Termination of Letter of Credit Commitment Period. (a)
Notwithstanding any other provision hereof, in the event that any restrictions
or limitations are imposed upon or determined or held to be applicable to the
Issuing Bank, any Participating Lender or the Borrower by, under or pursuant to
any law or regulation (Federal, state or local) now or hereafter in effect or by
reason of any interpretation thereof by any court or Governmental Authority
(including any interpretation by the Comptroller of the Currency as to the
applicability of 12 U.S.C. ' 84 or any substitute statute, as now or hereafter
in effect, to the transactions contemplated hereby), which would prevent such
<PAGE>   76
                                                                              75


Participating Lender from legally incurring liability under a Letter of Credit
issued or to be issued pursuant hereto, then such Participating Lender shall
give prompt written notice thereof to the Agent (which shall notify the
Borrower, the Issuing Bank and each other Participating Lender thereof as soon
as reasonably practicable), whereupon the obligation of the Issuing Bank to
issue additional Letters of Credit pursuant hereto shall be suspended until the
Agent shall be advised that such event is no longer continuing or until such
event shall have continued for a period of 180 days, after which period the
obligation of the Issuing Bank to issue additional Letters of Credit pursuant
hereto shall terminate.

         (b) The Borrower may permanently terminate, or from time to time in
part permanently reduce, the Letter of Credit Commitment, in each case upon at
least three Business Days' prior written or telex notice to the Agent and the
Issuing Bank; provided that the Letter of Credit Commitment shall not be less
than the Letter of Credit Exposure at the time or greater than the Revolving
Credit Commitments at the time.

         SECTION 3.08. Resignation or Removal of Issuing Bank. (a) The Issuing
Bank may resign at any time by giving 60 days' notice to the Agent, the Lenders
and the Borrower, and may be removed at any time by the Borrower by notice to
the Issuing Bank, the Agent and the Lenders. Upon any such resignation or
removal, the Borrower shall (within 60 days after such notice of resignation or
removal) either appoint a successor, or terminate the unutilized Letter of
Credit Commitment; provided, however, that, if the Borrower elects to terminate
the unutilized Letter of Credit Commitment, the Borrower may at any time
thereafter that the Revolving Credit Commitments are in effect reinstate the
Letter of Credit Commitment in connection with the appointment of a successor
Issuing Bank. Subject to paragraph (b) below, upon the acceptance of any

of Credit hereunder. The acceptance of any appointment as Issuing Bank hereunder

         (b) After the resignation or removal of the Issuing Bank hereunder the
retiring Issuing Bank shall remain a party hereto and shall continue to have all

such resignation or removal, but shall not be required to issue additional
Letters of Credit.

                                                                              77


obligations under each of the Loan Documents and each other agreement or
instrument contemplated thereby to which it is or will be a party and, in the
case of the Borrower, to borrow hereunder.

         SECTION 4.02. Authorization. The execution, delivery and performance by
each of the Borrower and each Subsidiary of each of the Loan Documents to which
it is or will be a party, the borrowings hereunder and the issuance of Letters
of Credit hereunder, the grant of the security interests contemplated by the
Security Documents, and the refinancing of indebtedness incurred under the Short
Term Credit Agreement (collectively, the "Transactions") (a) have been duly
authorized by all requisite corporate and, if required, stockholder action and
(b) will not (i) violate (A) any provision of any law, statute, rule or
regulation, or of the certificate or articles of incorporation or other
constitutive documents or By-laws of the Borrower or any Subsidiary, (B) any
order of any Governmental Authority or (C) after giving effect to the
satisfaction of the condition specified in clause (n) of Section 5.02, any
provision of any indenture, agreement or other instrument to which the Borrower
or any Subsidiary is a party or by which any of them or any of their property is
or may be bound, other than indentures, agreements and other instruments which,
individually or in the aggregate, are not material to the Borrower and the
Subsidiaries, taken as a whole, and the violation of which will not result in a
Material Adverse Effect, (ii) after giving effect to the satisfaction of the
condition specified in clause (n) of Section 5.02, be in conflict with, result
in a breach of or constitute (alone or with notice or lapse of time or both) a
default under any such indenture, agreement or other instrument, other than
indentures, agreements and other instruments which, individually or in the
aggregate, are not material to the Borrower and the Subsidiaries, taken as a
whole, and the violation of which will not result in a Material Adverse Effect,
or (iii) result in the creation or imposition of any Lien upon any property or
assets of the Borrower or any Subsidiary, other than the security interests
contemplated by the Security Documents.
<PAGE>   79
                                                                              78


         SECTION 4.03. Enforceability. This Agreement has been duly executed and
delivered by the Borrower and constitutes, and each other Loan Document to which
the Borrower or any Subsidiary is or will be a party (when executed and
delivered by the Borrower or such Subsidiary) will constitute, a legal, valid
and binding obligation of the Borrower or such Subsidiary enforceable against
the Borrower or such Subsidiary in accordance with its terms (subject, as to the
enforcement of remedies, to applicable bankruptcy, reorganization, insolvency,
moratorium and similar laws affecting creditors' rights generally and to general
equitable principles).

         SECTION 4.04. Governmental Approvals. No action, consent or approval
of, or registration or filing with, or any other action by, any Governmental
Authority is or will be required in connection with any of the Transactions,
except (i) such as have been made or obtained and are in full force and effect
or (ii) such as the failure to make or obtain will not result, individually or
in the aggregate, in a Material Adverse Effect.

         SECTION 4.05. Financial Statements. The Borrower has heretofore
delivered or caused to be delivered to each Lender (i) a copy of its
consolidated balance sheet as of the end of, and related consolidated statements
of income, stockholders' equity and cash flows for, the year ended December 31,
1998, audited and reported on by PricewaterhouseCoopers, independent public
accountants and (ii) a copy of its consolidated balance sheet as of the end of,
and related consolidated statements of income, stockholders' equity and cash
flows for, the fiscal quarter and six-month period ended June 30, 1999,
certified by the Financial Officer of the Borrower. These financial statements,
including in the case of the annual financial statements the footnotes thereto,
have been prepared in accordance with GAAP consistently applied throughout the
periods indicated and disclose all material liabilities, direct or contingent,
of the Borrower and its Subsidiaries on a consolidated basis as of their
respective dates, required to be disclosed, and fairly present the financial
condition of the
<PAGE>   80
                                                                              79


Borrower and its Subsidiaries at the date thereof. The related statements of
income, stockholders' equity and cash flows fairly present the results of the
operations of the Borrower and its Subsidiaries on a consolidated basis and
their cash flows for the respective periods indicated.

         SECTION 4.06. No Material Adverse Change. There has been no material
adverse change in the business, assets, properties, operations or condition,
financial or otherwise, of the Borrower and the Subsidiaries, taken as a whole,
since December 31, 1998.

         SECTION 4.07. Title to Properties; Possession Under Leases; Accounts.
(a) Each of the Borrower and each Subsidiary has good and marketable title to,
or valid leasehold interests in, all its material properties (other than
railroad rights of way) and assets, except for minor defects in title that do
not interfere with its ability to conduct its business as currently conducted.
All such material properties and assets are free and clear of Liens other than
Liens permitted by Section 7.02. Each Subsidiary holds railroad rights of way
that are sufficient to conduct its railroad operations as currently conducted.

         (b) Each of the Borrower and each Subsidiary has complied with all
obligations under all leases to which it is a party, other than leases which,
individually or in the aggregate, are not material to the Borrower and the
Subsidiaries, taken as a whole, and the violation of which will not result in a
Material Adverse Effect, and all such leases are in full force and effect, other
than leases which, individually or in the aggregate, are not material to the
Borrower and the Subsidiaries, taken as a whole, and in respect of which the
failure to be in full force and effect will not result in a Material Adverse
Effect. Each of the Borrower and each Subsidiary enjoys peaceful and undisturbed
possession under all such leases with respect to which it is the lessee, other
than leases which, individually or in the aggregate, are not material to the
Borrower and the Subsidiaries, taken as a whole, and in respect of which the
failure to enjoy peaceful
<PAGE>   81
                                                                              80


and undisturbed possession will not result in a Material Adverse Effect.

         (c) Since December 31, 1998, none of the Subsidiaries (or any of their
predecessors) has taken any action other than in the ordinary course of business
to collect any of its Accounts or has changed in any material respect its credit
criteria or collection policies concerning its Accounts. Other than as reflected
in the allowance for doubtful accounts, as of the Restatement Closing Date, each
Account constitutes a legal, valid and binding obligation of the Account Debtor
enforceable against the Account Debtor in accordance with its terms, except as
the enforceability thereof may be limited by bankruptcy, insolvency, moratorium
and other similar laws affecting the enforcement of creditors' rights generally,
and is not subject to any Lien except pursuant to this Agreement and the
Security Documents.

         SECTION 4.08. Identity of Subsidiaries. Schedule 4.08 sets forth as of
the Restatement Closing Date a list of all Subsidiaries of the Borrower, each of
which is wholly owned, directly or indirectly, by the Borrower.

         SECTION 4.09. Litigation; Compliance with Laws. (a) Except as set forth
in Schedule 4.09, there are not any actions, suits or proceedings at law or in
equity or by or before any Governmental Authority now pending or, to the
knowledge of the Borrower, threatened against or directly affecting the Borrower
or any Subsidiary or any business, property or rights of any such person (i)
which involve any Loan Document or any of the Transactions or (ii) which could
reasonably be expected to, individually or in the aggregate, result in a
Material Adverse Effect.

         (b) Neither the Borrower nor any of the Subsidiaries is in violation of
any law, rule or regulation, or in default with respect to any judgment, writ,
injunction or decree of any Governmental Authority, where such violation or
default could reasonably be expected to result in a Material Adverse Effect.
<PAGE>   82
                                                                              81


         SECTION 4.10. Agreements. Neither the Borrower nor any of the
Subsidiaries is in default in any manner under any provision of any indenture or
other agreement or instrument evidencing Indebtedness, or any other material
agreement or instrument, to which it is a party, or by which it or any of its
properties or assets are or may be bound, where such default could reasonably be
expected to result in a Material Adverse Effect.

         SECTION 4.11. Federal Reserve Regulations. (a) Neither the Borrower nor
any of the Subsidiaries is engaged principally, or as one of its important
activities, in the business of extending credit for the purpose of purchasing or
carrying Margin Stock.

         (b) No part of the proceeds of any Loan will be used, whether directly
or indirectly, and whether immediately, incidentally or ultimately, (i) to
purchase or carry Margin Stock or to extend credit to others for the purpose of
purchasing or carrying Margin Stock or to refund indebtedness originally
incurred for such purpose, or (ii) for any purpose which entails a violation of,
or which is inconsistent with, the provisions of the Regulations of the Board,
including Regulation T, U or X.

         SECTION 4.12. Investment Company Act: Public Utility Holding Company
Act. Neither the Borrower nor any of the Subsidiaries is (a) an "investment
company" as defined in, or otherwise subject to regulation under, the Investment
Company Act of 1940 or (b) a "holding company" as defined in, or subject to
regulation under, the Public Utility Holding Company Act of 1935.

         SECTION 4.13. Use of Proceeds; Letters of Credit. The Borrower will use
the proceeds of the Loans only for the purposes specified in the preamble to
this Agreement. The Borrower will request the Issuing Bank to issue Letters of
Credit only for general corporate purposes in the ordinary course of its
business.
<PAGE>   83
                                                                              82


         SECTION 4.14. Tax Returns. Each of the Borrower and the Subsidiaries
has filed or caused to be filed all Federal, state and local tax returns
required to have been filed by it and has paid or caused to be paid all taxes
shown to be due and payable on such returns or on any assessments received by
it, except taxes that are being contested in accordance with Section 6.03.

         SECTION 4.15. Information Memoranda. The information contained in the
Information Memorandum dated July 1999 relating to the Borrower was, as of the
date of such Information Memorandum or the dates otherwise specified therein,
accurate in all material respects and does not contain any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein not misleading, provided that (a) the statements therein
describing documents and agreements are summary only and as such are qualified
in their entirety by reference to such documents and agreements, (b) to the
extent any such information therein was based upon or constitutes a forecast or
projection, the Borrower represents only that it acted in good faith and
utilized reasonable assumptions, due and careful consideration and the best
information known to it at the time in the preparation of such information, and
(c) as to the information which is specified as having been supplied by third
parties, other than Affiliates of the Borrower, the Borrower represents only
that it is not aware of any material misstatement or omission therein.

         SECTION 4.16. Employee Benefit Plans. The Borrower and each of its
ERISA Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the regulations and published interpretations
thereunder. No Reportable Event has occurred with respect to any Plan as to
which the Borrower or any ERISA Affiliate was required to file a report with the
PBGC, and the present value of all benefit liabilities (as defined in Section
4001(a)(16) of ERISA) under each Plan maintained by the Borrower or an ERISA
Affiliate (based on those assumptions used to fund such Plan) did not, as of the
<PAGE>   84
                                                                              83


date of this Agreement and, thereafter, as of the most recent annual actuarial
valuation applicable to each such Plan, exceed by a material amount the value of
the assets of such Plan. Neither the Borrower nor any ERISA Affiliate has
incurred any Withdrawal Liability that could reasonably be expected to result in
a Material Adverse Effect. Neither the Borrower nor any ERISA Affiliate has
received any notification that any Multiemployer Plan is in reorganization or
has been terminated, within the meaning of Title IV of ERISA, and no
Multiemployer Plan is reasonably expected to be in reorganization or to be
terminated, where such reorganization or termination has resulted or can
reasonably be expected to result, through increases in the contributions
required to be made to such Plan, in a Material Adverse Effect.

         SECTION 4.17. Labor Matters. There are no strikes against the Borrower
or any Subsidiary pending, other than any strikes which, individually or in the
aggregate, could not reasonably be expected to result in a Material Adverse
Effect. The hours worked and payment made to employees of the Borrower and each
Subsidiary have not been in violation in any material respect of the Fair Labor
Standards Act or any other applicable law dealing with such matters. All
payments due from the Borrower or any Subsidiary, or for which any claim may be
made against the Borrower or any Subsidiary, on account of wages and employee
health and welfare insurance and other benefits have been paid or accrued as a
liability on the books of the Borrower or such Subsidiary. The consummation of
the Transactions will not give rise to a right of termination or right of
renegotiation on the part of any union under any collective bargaining agreement
to which the Borrower or any Subsidiary (or any predecessor) is a party or by
which the Borrower or any Subsidiary (or any predecessor) is bound, other than
collective bargaining agreements which, individually or in the aggregate, are
not material to the Borrower and the Subsidiaries taken as a whole.

         SECTION 4.18. Environmental Matters. The Borrower and each Subsidiary
have complied in all material respects with all Federal, state, local and
regional statutes, ordinances, orders, judgments,
<PAGE>   85
                                                                              84


rulings and regulations relating to any matters of pollution or of environmental
regulation or control. Neither the Borrower nor any Subsidiary has received
written notice of any actual or claimed or asserted failure so to comply which
alone, or together with any other such notices which have been previously or
concurrently received, could reasonably be expected to result in a Material
Adverse Effect, other than in connection with failures which have been
corrected. No hazardous wastes, hazardous substances, hazardous materials, toxic
substances or toxic pollutants, as those terms are used in the Resource
Conservation and Recovery Act, the Comprehensive Environmental Response
Compensation and Liability Act, the Hazardous Materials Transportation Act, the
Toxic Substance Control Act, the Clean Air Act and the Clean Water Act, are
managed on any property of the Borrower or any Subsidiary in material violation
of any regulations promulgated pursuant thereto or any other applicable law.

         SECTION 4.19. Solvency. (a) The fair salable value of the assets of
each of the Borrower and each of the Subsidiaries exceeds as of the Restatement
Closing Date and will, immediately following the making of each Loan made on the
Restatement Closing Date and after giving effect to the application of the
proceeds of such Loans, exceed the amount that will be required to be paid on or
in respect of its existing debts and other liabilities (including contingent
liabilities) as they mature.

         (b) The assets of each of the Borrower and each of the Subsidiaries do
not as of the Restatement Closing Date and will not, immediately following the
making of each Loan made on the Restatement Closing Date and after giving effect
to the application of the proceeds of such Loans, constitute unreasonably small
capital to carry out its business as conducted or as proposed to be conducted.

         (c) The Borrower does not intend to or permit any Subsidiary to, and
does not believe that the Borrower or any Subsidiary will, incur debts beyond
its ability to pay such debts as they mature taking into account the timing of
and amounts of cash to be received by the Borrower or any such
<PAGE>   86
                                                                              85


Subsidiary and the timing of and amounts of cash to be payable on or in respect
of indebtedness of the Borrower or any such Subsidiary.

         SECTION 4.20. Capitalization. On the Original Closing Date, the
authorized capital stock of the Borrower consisted of (a) 10,000 shares of
Voting Stock and (b) 10,000 shares of Non-Voting Stock, all of which shares of
Voting Stock and Non-Voting Stock are issued and outstanding, except for such
shares that have been redeemed or repurchased pursuant to the Transtar, Inc.
Equity Participation Plan or the Additional Management Equity Plan. All of the
outstanding shares of capital stock of the Borrower have been duly authorized
and validly issued and are fully paid and nonassessable. All of the outstanding
shares of capital stock of each Subsidiary have been duly authorized and are
validly issued, are fully paid and nonassessable, and are owned, beneficially
and of record, by the Borrower or any other wholly owned Subsidiary, free and
clear of any Liens, other than pursuant to the Pledge Agreement. No shares of
capital stock of the Borrower or any Subsidiary are reserved for issuance and
there are no outstanding options, warrants, rights, subscriptions, claims of any
character, agreements, obligations, convertible or exchangeable securities, or
other commitments, contingent or otherwise, relating to the capital stock of the
Borrower or any Subsidiary, pursuant to which the Borrower or any Subsidiary is
or may become obligated to issue or exchange any shares of capital stock of the
Borrower or any Subsidiary except, in the case of the Borrower, for shares and
options to purchase shares of Voting Stock and Non-Voting Stock of the Borrower
issued or reserved for issuance pursuant to the terms of the Transtar, Inc.
Equity Participation Plan or the Additional Management Equity Plan. On the
Original Closing Date, and after giving effect to all transactions that occurred
on such date, Blackstone entities own, directly or indirectly, 5,100 shares of
Voting Stock and 5,100 shares of Non-Voting Stock; USX owns, beneficially and of
record, 4,900 shares of Voting Stock and 3,900 shares of Non-Voting Stock; and
members of management and employees of the Borrower and its Subsidiaries own of
record 700 shares of Non-Voting Stock; and in the case of each of Blackstone and
USX, all such shares are
<PAGE>   87
                                                                              86


owned free and clear of any Liens, other than pursuant to the Stockholders'
Agreement.

         SECTION 4.21. Security Interests. (a) The security interests created in
favor of the Agent for the benefit of the Lenders under the Pledge Agreement
constitute first-priority, perfected security interests in the Pledged
Securities, and such Pledged Securities are subject to no Liens or security
interests of any other person. No filings or recordings, other than those which
have been made, are or will be required in order to perfect the security
interests in the Pledged Securities created under the Pledge Agreement.

         (b) Upon the filing of Uniform Commercial Code financing statements in
the appropriate filing office in the jurisdictions listed in Schedule 4.21, the
security interests created in favor of the Agent for the benefit of the Lenders
under the Security Agreement will constitute first-priority, perfected security
interests in the Collateral (as defined in the Security Agreement), subject only
to Liens permitted by Section 7.02.

         (c) The assets and properties of the Borrower and the Subsidiaries are
not subject to a negative pledge or other restriction which prohibits or
restricts the grant of a security interest in or Lien on such assets and
properties, except (i) the restriction contained in Section 7.02 and (ii) except
for a portion of such assets and properties that does not constitute a material
portion of the assets and properties of the Borrower and the Subsidiaries, taken
as a whole.

         SECTION 4.22. Year 2000 Matters. Any reprogramming required to permit
the proper functioning, in and following the year 2000, of (i) the Borrower's
and the Subsidiaries' computer systems and (ii) equipment containing embedded
microchips (including systems and equipment supplied by others or with which the
Borrower's or the Subsidiaries' systems interface) and the testing of all such
systems and equipment, as so reprogrammed, will be completed in all material
respects prior to any expected
<PAGE>   88
                                                                              87


failure date caused by a year 2000 problem and in any case prior to December 31,
1999. The cost to the Borrower of such reprogramming and testing and of the
reasonably foreseeable consequences of year 2000 to the Borrower (including
reprogramming errors and the failure of others' systems or equipment) could not
reasonably be expected to result in a Potential Event of Default, an Event of
Default or result in a Material Adverse Effect. Except for such of the
reprogramming referred to in the immediately preceding sentence as may be
necessary, the computer and management information systems of the Borrower and
the Subsidiaries are, and, with ordinary course upgrading and maintenance, will
continue for the term of this Agreement to be, sufficient to enable the Borrower
and the Subsidiaries to conduct their business without the occurrence of any
Material Adverse Effect.


                                   ARTICLE V

                                   CONDITIONS

observed or performed, and at the time of and immediately after such Borrowing
or issuance no Event of Default or Potential Event of Default shall have

         Each Borrowing and issuance of a Letter of Credit shall be deemed to
constitute a representation and warranty by the Borrower on the date of such
Borrowing or issuance as to the matters specified in paragraphs (b) and (c) of
this Section. Continuations and conversions of outstanding Borrowings pursuant
to Section 2.10 shall not be deemed to be new Borrowings for the purposes of
this Section.

         SECTION 5.02. Restatement Closing Date. The effectiveness of the
amendment and restatement of the Original Credit Agreement by this Agreement and

                                                                              89

sponsor of a Multiemployer Plan that such Multiemployer Plan is in

Subsidiary not to be, a valid, perfected, first priority (except as otherwise
expressly provided in such Security Document) security interest in the
securities, assets or properties covered thereby, other than in respect of
assets and properties which, individually and in the aggregate, are not material
to the Borrower and the Subsidiaries taken as a whole or in respect of which the
failure of the security interests in respect thereof to be valid, perfected
first priority security interests will not in the reasonable judgment of the
Agent or the Required Lenders have a Materially Adverse Effect on the rights and
benefits of the Lenders under the Loan Documents taken as a whole;

         (n) the Stockholders' Agreement shall be amended, modified,
supplemented, or waived in any respect which is materially adverse to the
interests of the Lenders, or is released or terminated, without the prior
written consent of the Required Lenders; or

kind, all of which are hereby expressly waived by the Borrower, anything
contained herein or in any other Loan Document to the contrary notwithstanding,

contemplated by Section 3.06 and (iv) exercise remedies available under the
Guarantee Agreement and the Security Documents or otherwise; and in any event
with respect to the Borrower described in paragraph (g) or (h) above, the
Commitments and the Letter of Credit Commitment shall automatically terminate

thereon and any unpaid accrued Fees and all other liabilities of the Borrower

herewith, or be required to ascertain or to make any inquiry concerning the
performance or observance by the Borrower of any of the terms, conditions,
covenants or agreements contained in any Loan Document. The Agent shall not be
responsible to the Lenders or the holders of the Notes or the Issuing Bank for
the due execution, genuineness, validity, enforceability or effectiveness of
this Agreement, the Notes or any other Loan Documents or other instruments or
agreements. The Agent may deem and treat the payee of any Note as the owner
thereof for all purposes hereof until it shall have received from the payee of
such Note notice, given as provided herein, of the transfer thereof. The Agent
shall in all cases be fully protected in acting, or refraining from acting, in
accordance with written instructions signed by the Required Lenders (and the
Issuing Bank, with respect to Letters of Credit) and, except as otherwise
specifically provided herein, such instructions and any action or inaction
pursuant thereto shall be binding on all the Lenders and each subsequent holder
of any Note and the Issuing Bank. The Agent and the Issuing Bank shall, in the
absence of knowledge to the contrary, be entitled to rely on any instrument or
document believed by either of them in good faith to be genuine and correct and
to have been signed or sent by the proper person or persons. Neither the Agent
nor the Issuing Bank nor any of their respective

                                                                             116


directors, officers, employees or agents shall have any responsibility to the
Borrower on account of the failure of or delay in performance or breach by any
Lender (or, in the case of the Agent, by the Issuing Bank) of any of its
obligations hereunder or to any Lender (or, in the case of the Agent, the
Issuing Bank) on account of the failure of or delay in performance or breach by
any other Lender (or, in the case of the Agent, the Issuing Bank) or the
Borrower of any of their respective obligations hereunder or under any other
Loan Document or in connection herewith or therewith. The Agent and the Issuing
Bank may execute any and all duties hereunder by or through agents or employees
and shall be entitled to rely upon the advice of legal counsel selected by
either of them with respect to all matters arising hereunder and shall not be
liable for any action taken or suffered in good faith by either of them in
accordance with the advice of such counsel.

         The Lenders hereby acknowledge that neither the Agent nor the Issuing
Bank shall be under any duty to take any discretionary action permitted to be
taken by it pursuant to the provisions of this Agreement or any other Loan
Document unless it shall be requested in writing to do so by the Required
Lenders.

         Subject to the appointment and acceptance of a successor Agent as
provided below, the Agent may resign at any time by notifying the Lenders, the
Issuing Bank and the Borrower. Upon any such resignation, the Required Lenders
shall have the right to appoint a successor, which shall be reasonably
satisfactory to the Borrower. If no successor shall have been so appointed by
the Required Lenders and shall have accepted such appointment within 30 days
after the retiring Agent gives notice of its resignation (or if the Borrower
shall have reasonably objected to the appointment of such successor), then the
retiring Agent may, on behalf of the Lenders, appoint a successor Agent which
shall be a bank with an office in New York, New York, having a combined capital
and surplus of at least $500,000,000 or an Affiliate of any such bank. Upon the
acceptance of any appointment as Agent hereunder by a successor bank, such
successor shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring
<PAGE>   118
                                                                             117


Agent and the retiring Agent shall be discharged from its duties and obligations
hereunder. After the Agent's resignation hereunder, the provisions of this
Article and Section 10.05 shall continue in effect for its benefit in respect of
any actions taken or omitted to be taken by it while it was acting as Agent.

         With respect to the Loans made by it hereunder and the Notes issued to
it and the Letter of Credit participations acquired by it, each of the Agent and
the Issuing Bank in its individual capacity and not as Agent or the Issuing
Bank, as the case may be, shall have the same rights and powers as any other
Lender and may exercise the same as though it were not the Agent or the Issuing
Bank, as the case may be, and the Agent and its Affiliates and the Issuing Bank
and its Affiliates may accept deposits from, lend money to and generally engage
in any kind of business with the Borrower or any Subsidiary or other Affiliate
thereof as if it were not the Agent or the Issuing Bank, as the case may be.

         Each Lender agrees (i) to reimburse each of the Agent and the Issuing
Bank, on demand, in the amount of such Lender's pro rata share (based on its
Commitment hereunder) of any expenses incurred for the benefit of the Lenders by
the Agent or the Issuing Bank, including counsel fees and compensation of agents
paid for services rendered on behalf of the Lenders, which shall not have been
reimbursed by the Borrower and (ii) to indemnify and hold harmless each of the
Agent and the Issuing Bank and any of their respective directors, officers,
employees or agents, on demand, in the amount of such pro rata share, from and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against it in
its capacity as the Agent or the Issuing Bank, as the case may be, or any of
them in any way relating to or arising out of this Agreement or any other Loan
Document or any action taken or omitted by it or any of them under this
Agreement or any other Loan Document, to the extent the same shall not have been
reimbursed by the Borrower; provided that no Lender shall be liable to the Agent
or the Issuing Bank for any portion of such liabilities,
<PAGE>   119
                                                                             118


obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the gross negligence or wilful
misconduct of the Agent or the Issuing Bank, as the case may be, or any of their
respective directors, officers, employees or agents.

         Each Lender acknowledges that it has, independently and without
reliance upon the Agent, the Issuing Bank or any other Lender and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement. Each Lender also
acknowledges that it will, independently and without reliance upon the Agent,
the Issuing Bank or any other Lender and based on such documents and information
as it shall from time to time deem appropriate, continue to make its own
decisions in taking or not taking action under or based upon this Agreement or
any other Loan Document, any related agreement or any document furnished
hereunder or thereunder.

         Each Lender recognizes that applicable laws, rules, regulations or
guidelines of Governmental Authorities may require the Agent to determine
whether the transactions contemplated hereby should be classified as "highly
leveraged" or assigned any similar or successor classification, and that such
determination may be binding upon the other Lenders. Each Lender understands
that any such determination shall be made solely by the Agent based upon such
factors (which may include, without limitation, the Agent's internal policies
and prevailing market practices) as the Agent shall deem relevant and agrees
that the Agent shall have no liability for the consequences of any such
determination.

its interests, rights and obligations under this Agreement (including all or a
portion of its Commitment and the Loans at the time owing to it and the Notes
and participations in Letters of Credit held by it); provided, however, that (i)

the assigning Lender's entire Revolving Credit Commitment and all the Term Loans
at the time owing to it (or, prior to the Restatement Closing Date, such

with the Note or Notes subject to such assignment and a processing and

(except in the case of assignments on the Restatement Closing Date), (A) the
assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender under
this Agreement and (B) the assigning Lender thereunder shall, to the extent
provided in such assignment, be released from its obligations under this
Agreement (and, in the case of an Assignment and Acceptance covering all or the
remaining portion of an assigning Lender's rights and obligations under this
Agreement, such Lender shall cease to be a party hereto).

the most recent financial statements
<PAGE>   124
                                                                             123


delivered pursuant to Section 6.04 and such other documents and information as
it has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance; (iv) such assignee will independently and
without reliance upon the Agent, the Issuing Bank, such assigning Lender or any
other Lender and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit decisions in taking or
not taking action under this Agreement; (v) such assignee appoints and
authorizes the Agent to take such action as agent on its behalf and to exercise
such powers under this Agreement as are delegated to the Agent by the terms
hereof, together with such powers as are reasonably incidental thereto; and (vi)
such assignee agrees that it will perform in accordance with their terms all the
obligations which by the terms of this Agreement are required to be performed by
it as a Lender.

         (d) The Agent, acting for this purpose as agent for the Borrower, shall
maintain at one of its offices in The City of New York a copy of each Assignment
and Acceptance delivered to it and a 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 pursuant to the terms hereof from time to time (the
"Register"). The entries in the Register shall be conclusive in the absence of
manifest error and the Borrower, the Agent, the Issuing Bank and the Lenders
shall treat each person whose name is recorded in the Register pursuant to the
terms hereof as a Lender hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary. The Register shall be available for
inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable
time and from time to time upon reasonable prior notice.

         (e) Upon its receipt of a duly completed Assignment and Acceptance
executed by an assigning Lender and an assignee together with the Note or Notes
subject to such assignment, the processing and recordation fee referred to in
paragraph (b) above and the written consent to such assignments, if required
hereunder, of the Issuing Bank and the Borrower, the Agent shall (subject to the
consent of the Agent to such assignment,
<PAGE>   125
                                                                             124


if required), (i) accept such Assignment and Acceptance, (ii) record the
information contained therein in the Register and (iii) give prompt notice
thereof to the Borrower. No assignment shall be effective unless it has been
recorded in the Register as provided in this paragraph (e). Within five Business
Days after receipt of notice, the Borrower, at its own expense, shall execute
and deliver to the Agent, in exchange for the surrendered Note or Notes, a new
Note or Notes to the order of such assignee in a principal amount equal to, as
applicable, the Tranche B Term Loan Commitment, the Tranche A Term Loan
Commitment and/or Revolving Credit Commitment assumed by the assignee pursuant
to such Assignment and Acceptance and, if the assigning Lender has retained a
Tranche A Term Loan Commitment, Tranche B Term Loan Commitment and/or Revolving
Credit Commitment, a new Note or Notes to the order of such assigning Lender in
a principal amount equal to the Tranche A Term Loan Commitment, Tranche B Term
Loan Commitment and/or Revolving Credit Commitment retained by it; provided,
however, that any such Note or Notes shall comply with Section 2.04. Such new
Note or Notes shall be in an aggregate principal amount equal to the aggregate
principal amount of such surrendered Note or Notes; such new Notes shall be
dated the date of such surrendered Notes and shall otherwise be in substantially
the form of Exhibit A-1, A-2 or A-3 hereto, as appropriate. Canceled Notes shall
be returned to the Borrower.

         (f) Each Lender may without the consent of the Borrower, the Issuing
Bank or the Agent sell participations to one or more banks or other entities in
all or a portion of its rights and obligations under this Agreement (including
all or a portion of its Commitment and the Loans owing to it and the Notes and
participations in Letters of Credit held by it); provided, however, that (i)
such Lender's obligations under this Agreement shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties hereto for the
performance of such obligations, (iii) the participating banks or other entities
shall be entitled to the benefit of the cost protection provisions contained in
Sections 2.13, 2.15 and 2.18 to the same extent that the Lender from which such
participating bank or other entity acquired its participation would be entitled
to the benefit of such cost protection
<PAGE>   126
                                                                             125


provisions, provided that the Borrower shall not be required to reimburse the
participating banks or other entities pursuant to Section 2.13, 2.15 or 2.18 in
an amount which exceeds the amount that would have been payable thereunder to
such Lender had such Lender not sold such participation and (iv) the Borrower,
the Agent, the Issuing Bank and the other Lenders shall continue to deal solely
and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement, and such Lender shall retain the sole right to
enforce the obligations of the Borrower relating to the Loans and participations
in Letters of Credit and to approve any amendment, modification or waiver of any
provision of this Agreement (provided that the participating bank or other
entity may be provided with the right to approve amendments, modifications or
waivers affecting it with respect to any decrease in the Fees payable hereunder,
any change in the amount of principal of or decrease in the rate at which
interest is payable on the Loans, or extend the dates fixed for scheduled
payments of principal of or interest on the Loans or the release or substitution
of material amounts of collateral under any Security Document (other than as
permitted in any Loan Document)).

         (g) In the event that Standard & Poor's Corporation, Moody's Investors
Service, Inc. or Thompson's BankWatch shall, after the date that any
Participating Lender becomes a Participating Lender, downgrade the long-term
certificate of deposit ratings of such Participating Lender, and the resulting
ratings shall be below BBB-, Baa3 and C, respectively, or the equivalent, then
the Issuing Bank shall have the right, but not the obligation, at its own
expense, upon notice to such Participating Lender and the Agent, to replace such
Participating Lender with an assignee (in accordance with and subject to the
restrictions contained in Section 10.04(b)), and such Participating Lender
hereby agrees to transfer and assign without recourse (in accordance with and
subject to the restrictions contained in Section 10.04(b)) all its interests,
rights and obligations in respect of its Revolving Credit Commitment and Letter
of Credit Exposure to such assignee; provided, however, that (i) no such
assignment shall conflict with any law, rule or regulation or order of any
Governmental
<PAGE>   127
                                                                             126


Authority and (ii) the Issuing Bank or such assignee, as the case may be, shall
pay to such Participating Lender in immediately available funds on the date of
such assignment the principal of and interest accrued to the date of payment on
the Revolving Credit Loans made by such Participating Lender hereunder, the
amount of Letter of Credit Disbursements funded by such Participating Lender
together with interest accrued thereon to the date of payment and all other
amounts accrued for such Participating Lender's account or owed to it hereunder
in respect of either thereof.

         (h) Any Lender may, in connection with any assignment or participation
or proposed assignment or participation pursuant to this Section, disclose to
the assignee or participant or proposed assignee or participant any information
relating to the Borrower furnished to such Lender by or on behalf of the
Borrower, provided that, prior to any such disclosure, each such assignee or
participant or proposed assignee or participant shall execute an agreement
whereby such assignee or participant shall agree (subject to customary
exceptions) to preserve the confidentiality of any confidential information
relating to the Borrower received from such Lender.

         (i) The Borrower shall not assign or delegate any of its respective
rights and duties hereunder. Except as provided in Section 3.09, the Issuing
Bank may not assign or delegate any of its respective rights and duties
hereunder without the prior written consent of the Borrower and the Agent.

         (j) Any Lender may at any time assign all or any portion of its rights
under this Agreement and the Notes to a Federal Reserve Bank to secure
extensions of credit by such Federal Reserve Bank to such Lender; provided that
no such assignment shall release a Lender from any of its obligations hereunder
or substitute any such Federal Reserve Bank for such Lender as a party hereto.

         SECTION 10.05. Expenses: Indemnity. (a) The Borrower agrees to pay all
out-of-pocket expenses incurred by the Agent and the Issuing Bank in connection
with the preparation of this Agreement and the other
<PAGE>   128
                                                                             127


Loan Documents or in connection with any amendments, modifications or waivers of
the provisions hereof or thereof (whether or not the transactions hereby
contemplated shall be consummated) or incurred by the Agent, the Issuing Bank or
any Lender in connection with the enforcement or protection of their rights in
connection with this Agreement and the other Loan Documents or in connection
with the Loans made or the Notes or Letters of Credit issued hereunder,
including the fees and disbursements of Cravath, Swaine & Moore, counsel for the
Agent, and, in connection with any such enforcement or protection, the fees and
disbursements of any other counsel for the Agent, the Issuing Bank or any Lender
(including, in connection with any such enforcement or protection, the allocated
costs of in house counsel). The Borrower further agrees that it shall indemnify
the Lenders from and hold them harmless against any documentary taxes,
assessments or charges made by any Governmental Authority by reason of the
execution and delivery of this Agreement or any of the other Loan Documents.

         (b) The Borrower agrees to indemnify the Agent, the Issuing Bank, each
Lender and its directors, officers, employees and agents (each such person being
called an "Indemnitee") against, and to hold each Indemnitee harmless from, any
and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees and expenses, incurred by or asserted against any
Indemnitee arising out of, in any way connected with, or as a result of (i) the
execution or delivery of this Agreement or any other Loan Document or any
agreement or instrument contemplated thereby, the performance by the parties
thereto of their respective obligations thereunder or the consummation of the
Transactions, (ii) the use of any Letter of Credit or the proceeds of the Loans
or (iii) any claim, litigation, investigation or proceeding relating to any of
the foregoing, whether or not any Indemnitee is a party thereto; provided that
such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses result from the
gross negligence or wilful misconduct of such Indemnitee.
<PAGE>   129
                                                                             128


         (c) The provisions of this Section shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or any investigation made by or on behalf
of the Agent, the Issuing Bank or any Lender. All amounts due under this Section
shall be payable not later than 10 Business Days after written demand therefor.

         SECTION 10.06. Right of Setoff. If an Event of Default shall have
occurred and be continuing and the Agent shall have declared, or the Required
Lenders shall have requested the Agent to declare, the Loans immediately due and
payable pursuant to Article VIII, each Lender (including the Issuing Bank in its
capacity as such) is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower against any of and all the obligations of the Borrower
now or hereafter existing under this Agreement and other Loan Documents held by
such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement or such other Loan Document and although such
obligations may be unmatured. The rights of each Lender under this Section are
in addition to other rights and remedies (including other rights of setoff)
which such Lender may have.

         SECTION 10.07. APPLICABLE LAW. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK.

         SECTION 10.08. Waivers; Amendment. (a) No failure or delay of the
Agent, the Issuing Bank or any Lender in exercising any power or right hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right or power, or any
<PAGE>   130
                                                                             129


abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or power. The rights and remedies of the Agent, the Issuing Bank and the
Lenders hereunder and under the other Loan Documents are cumulative and
exclusive of any rights or remedies which they would otherwise have. No waiver
of any provision of this Agreement or any other Loan Document or consent to any
departure by the Borrower therefrom shall in any event be effective unless the
same shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given. No notice or demand on the Borrower in any case shall entitle the
Borrower to any other or further notice or demand in similar or other
circumstances. Each holder of any of the Notes shall be bound by any amendment,
modification, waiver or consent authorized as provided herein, whether or not
such Note shall have been marked to indicate such amendment, modification,
waiver or consent.

         (b) Neither this Agreement, the Guarantee Agreement nor any of the
Security Documents nor any provision hereof or thereof may be waived, amended or
modified except, in the case of this Agreement, pursuant to an agreement or
agreements in writing entered into by the Borrower and the Required Lenders, or,
in the case of the Guarantee Agreement or any of the Security Documents,
pursuant to an agreement or agreements in writing entered into by the Borrower
and any of the Subsidiaries party thereto and the Collateral Agent and consented
to by the Required Lenders, provided that the foregoing shall not restrict the
ability of the Required Lenders to waive any Event of Default prior to the time
the Agent shall have declared, or the Required Lenders shall have requested the
Agent to declare, the Loans immediately due and payable pursuant to Article
VIII; provided, however, that no such agreement shall (i) change the principal
amount of, or extend the scheduled maturity of or any date for the scheduled
payment of any principal of or interest on, any Loan, or waive or excuse any
such payment or any part thereof, or reduce the rate of interest on any Loan,
without the prior written consent of each holder of a Note affected thereby
(provided that the
<PAGE>   131
                                                                             130


foregoing shall not restrict the ability of the Required Lenders to waive any
Event of Default (other than any Event of Default the waiver of which would
effectively result in any such change, extension, waiver or excuse, or
reduction), prior to the time the Agent shall have declared, or the Required
Lenders shall have requested the Agent to declare, the Loans immediately due and
payable), (ii) increase the Commitment or reduce the Commitment Fees of any
Lender without the prior written consent of such Lender, (iii) amend or modify
the provisions of Section 2.16, the provisions of this Section or the definition
of the "Required Lenders" without the prior written consent of each Lender or
(iv) permit the release (other than for purposes of substitution of collateral
of reasonably equivalent value) of any material amount of collateral under any
Security Document except as expressly permitted hereby or thereby without the
prior written consent of each Lender; provided further that no such agreement
shall amend, modify or otherwise affect the rights or duties of the Agent or the
Issuing Bank hereunder without the prior written consent of the Agent or the
Issuing Bank, as the case may be. Each Lender and each holder of a Note shall be
bound by any modification or amendment authorized by this Section regardless of
whether its Note shall have been marked to make reference thereto, and any
consent by any Lender or holder of a Note pursuant to this Section shall bind
any person subsequently acquiring a Note from it, whether or not such Note shall
have been so marked.

         SECTION 10.09. Interest Rate Limitation. Notwithstanding anything
herein or in the Notes to the contrary, if at any time the applicable interest
rate, together with all fees and charges which are treated as interest under
applicable law (collectively the "Charges"), as provided for herein or in any
other document executed in connection herewith, or otherwise contracted for,
charged, received, taken or reserved by any Lender, shall exceed the maximum
lawful rate (the "Maximum Rate") which may be contracted for, charged, taken,
received or reserved by such Lender in accordance with applicable law, the rate
of interest payable under the Note held by such Lender, together with all
Charges payable to such Lender, shall be limited to the Maximum Rate.

                                                                             131


         SECTION 10.10. Entire Agreement. This Agreement and the other Loan
Documents constitute the entire contract between the parties relative to the
subject matter hereof, except as provided in Section 2.05(b) and (c). Any
previous agreement among the parties with respect to the subject matter hereof
is superseded by this Agreement and the other Loan Documents. Nothing in this
Agreement or in the other Loan Documents, expressed or implied, is intended to
confer upon any party other than the parties hereto and thereto any rights,
remedies, obligations or liabilities under or by reason of this Agreement or the
other Loan Documents.

         SECTION 10.11. Severability. In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby. The parties shall endeavor
in good-faith negotiations to replace the invalid, illegal or unenforceable
provisions with valid provisions the economic effect of which comes as close as
possible to that of the invalid, illegal or unenforceable provisions.

         SECTION 10.12. Confidentiality. Except as otherwise provided in Section
10.04(h), each of the Agent, the Issuing Bank and each of the Lenders agrees to
keep confidential (and to cause its respective officers, directors, employees,
agents and representatives to keep confidential) and, at the Borrower's request
(except as provided below), promptly to return to the Borrower or destroy, after
the termination of this Agreement, the Information and all copies thereof,
extracts therefrom and analyses or other materials based thereon, except that
the Agent, the Issuing Bank or any Lender shall be permitted to disclose
Information (a) to such of its respective officers, directors, employees, agents
and representatives as need to know such Information, (b) to the extent required
by applicable
<PAGE>   133
                                                                             132


laws and regulations or by any subpoena or similar legal process, or requested
by any bank regulatory authority, or (c) to the extent such Information (i)
becomes publicly available other than as a result of a breach of this Agreement,
or (ii) becomes available to the Agent, the Issuing Bank or any Lender on a
non-confidential basis from a source other than the Borrower or any Subsidiary.
For the purposes of this Section, "Information" shall mean all financial
statements, certificates, reports and information (including all analyses,
compilations and studies prepared by the Agent, the Issuing Bank or any Lender
based on any of the foregoing) which are received from the Borrower or any of
the Subsidiaries which relates to the Borrower, any Subsidiary, any shareholder
of the Borrower or any employee, customer or supplier of the Borrower or any
Subsidiary, other than which were available to the Agent, the Issuing Bank or
any Lender on a non-confidential basis prior to its disclosure thereto by the
Borrower or any Subsidiary, and which are, in the case of Information provided
after the date hereof, clearly identified at the time of delivery as
confidential.

         SECTION 10.13. Counterparts. This Agreement may be executed in two or
more counterparts, each of which shall constitute an original but all of which
when taken together shall constitute but one contract, and shall become
effective as provided in Section 10.03. Delivery of an executed counterpart of a
signature page of this Agreement by telecopy shall be effective as delivery of a
manually executed counterpart to this Agreement.

         SECTION 10.14. Headings. Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of this
Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

         SECTION 10.15. Jurisdiction; Consent to Service of Process. (a) The
Borrower hereby irrevocably and unconditionally submits, for itself and its
property, to the nonexclusive jurisdiction of any New York State court or
<PAGE>   134
                                                                             133


Federal court of the United States of America sitting in New York City, and any
appellate court from any thereof, in any action or proceeding arising out of or
relating to this Agreement or the other Loan Documents, or for recognition or
enforcement of any judgment, and each of the parties hereto hereby irrevocably
and unconditionally agrees that all claims in respect of any such action or
proceeding may be heard and determined in such New York State or, to the extent
permitted by law, in such Federal court. Each of the parties hereto agrees that
a final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this Agreement shall affect any right that the
Borrower or any Lender may otherwise have to bring any action or proceeding
relating to this Agreement or the other Loan Documents in the courts of any
jurisdiction.

         (b) The Borrower hereby irrevocably and unconditionally waives, to the
fullest extent it may legally and effectively do so, any objection which it may
now or hereafter have to the laying of venue of any suit, action or proceeding
arising out of or relating to this Agreement or the other Loan Documents in any
New York State or Federal court. Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

         (c) Each party to this Agreement irrevocably consents to service of
process in the manner provided for notices in Section 10.01. Nothing in this
Agreement will affect the right of any party to this Agreement to serve process
in any other manner permitted by law.

         SECTION 10.16. Original Credit Agreement; Effectiveness of the
Amendment and Restatement. Until this Agreement becomes effective upon the
satisfaction, or waiver by the required Lenders and each Lender with a Tranche B
Term Loan Commitment, of the conditions set forth in Section 5.02, the Original
Credit Agreement shall remain in full force and effect and shall not be affected
<PAGE>   135
                                                                             134


hereby. After the Restatement Closing Date, all obligations of the Borrower
under the Original Credit Agreement shall become obligations of the Borrower
hereunder, secured by the Security Documents, and the provisions of the Original
Credit Agreement shall be superseded by the provisions hereof.

         IN WITNESS WHEREOF, the Borrower, the Agent, the Issuing Bank and the
Lenders have caused this Agreement to be duly executed by their respective
authorized officers as of the day and year first above written.
