                          "CREDIT AGREEMENT dated as of July 7, 2000 (this
                    "Agreement"), among MORRISON KNUDSEN CORPORATION; the
                    Lenders (as defined in Article I); BANK OF MONTREAL, as
                    Syndication Agent, and CREDIT SUISSE FIRST BOSTON, a bank
                    organized under the laws of Switzerland, acting through its
                    New York Branch ("CSFB"), as administrative agent (in such
                    capacity, the "Administrative Agent"), as collateral agent
                    (in such capacity, the "Collateral Agent") and as an issuer
                    of Letters of Credit.

          The Borrower intends to acquire (the "Acquisition") from Raytheon
Company and Raytheon Engineers & Constructors International, Inc., a wholly
owned subsidiary of Raytheon Company ("RECI" and, together with Raytheon
Company, the "Seller"), the capital stock of the subsidiaries of RECI and
certain other assets of RECI (collectively, the "Acquired Business"), and to
assume certain liabilities of RECI, pursuant to the Purchase Agreement (such
term and each other capitalized term used but not otherwise defined herein
having the meaning assigned to it in Article I). The purchase price for the
Acquired Business will be calculated using specified balance sheet items of the
Acquired Business as of April 30, 2000, as specified in the Purchase Agreement.
Subject to post-closing adjustments provided for in the Purchase Agreement, the
Borrower expects that the purchase price for the Acquired Business will be
approximately $10,000,000 and that it will assume net liabilities of RECI of
approximately $500,000,000. In connection with the Acquisition, the Borrower
will (a) repay all amounts outstanding under the Existing Credit Facility, (b)
obtain the credit facilities provided under this Agreement and (c) either (i)
issue Senior Notes in an aggregate principal amount not less than $275,000,000
in a public offering or in a Rule 144A or other private placement or (ii) if
unable to issue Senior Notes, borrow Unsecured Loans in an aggregate principal
amount not less than $275,000,000.

          The Borrower has requested the Lenders to extend credit hereunder in
the form of (a) Tranche A Term Loans during the Tranche A Availability Period in
an aggregate principal amount not in excess of $100,000,000, (b) Tranche B Term
Loans on the Closing Date in an aggregate principal amount not in excess of
$400,000,000, (c) Revolving Loans and Swingline Loans at any time and from time
to time prior to the Revolving Credit Maturity Date in an aggregate principal
amount at any time outstanding not in excess of $500,000,000 minus the L/C
Exposure at such time and (d) Letters of Credit in an aggregate stated amount at
any time outstanding that will not result in the L/C Exposure exceeding
$500,000,000. The proceeds of the Tranche A Term Loans made on the Closing Date
and the Tranche B Loans are to be used by the Borrower solely (i) to finance the
Acquisition, (ii) to refinance the Existing Credit Facility, (iii) to refinance
the Existing Receivables Facility, (iv) to pay fees and expenses related to the
Closing Date Transactions, (v) for working capital and to provide for certain
assumed project obligations of the Acquired Business and (vi) for general
corporate purposes. The proceeds of the Tranche A Term Loans, the Revolving
Loans and the Swingline Loans made after the Closing Date are to be used by the
Borrower and the Subsidiaries for general corporate purposes, including
permitted acquisitions and to assist the Borrower and its Subsidiaries in
performing their obligations under their respective Government Contracts. The
Letters of Credit are to be used to support obligations incurred by the Borrower
and the Subsidiaries in the course of their businesses.

          The Lenders are willing to extend such credit to the Borrower and the
Issuing Banks are willing to issue Letters of Credit for the account of the
Borrower on the terms and subject to the conditions set forth herein.
Accordingly, the parties hereto agree as follows:

                                  Definitions

shall be determined without regard to clause (b) of the preceding sentence until
the circumstances giving rise to such inability no longer exist. Any change in
the Alternate Base Rate due to a change in the Prime Rate or the Federal Funds
Effective Rate shall be effective on the effective date of such change in the

security interest in any Collateral under any Pledge Agreement or Security
Agreement if it would be a violation of applicable law for such Subsidiary to

accrue to the Lenders, justify taking such action, (ii) the Westinghouse

Agreements or to pledge or grant any security interest in any Collateral under
any Pledge Agreement or Security Agreement at any time when they are prohibited

Agreement or the Security Documents. Further, the Borrower and the Subsidiaries
will not be required to create Liens on particular assets under the Security
Documents if, in the judgment of the Collateral Agent, in consultation with the
Borrower, the expense, tax or regulatory consequences or difficulty of creating
such Liens with respect to such assets would not, in light of the benefits to
accrue to the Lenders, justify taking such action. The Collateral Agent is
expressly authorized upon the request of the Borrower to release any Guarantee
or security interest previously delivered or created that at the time of such
request is not required to remain in effect under this definition and the other

be construed in accordance with GAAP, as in effect from time to time; provided,
however, that, if the Borrower notifies the Administrative Agent that the
Borrower requests an amendment to any provision hereof to eliminate the effect
of any change occurring after the date hereof in GAAP or in the application
thereof on the operation of such provision (or if the Administrative Agent
notifies the Borrower that the Required Lenders request an amendment to any
provision hereof for such purpose), regardless of whether any such notice is
given before or after such change in GAAP or in the application thereof, then
such provision shall be interpreted on the basis of GAAP as in effect and
applied immediately before such change shall have become effective until such
notice shall have been withdrawn or such provision amended in accordance
herewith.

         (b) All computations required to be made hereunder to demonstrate pro
forma compliance with any covenant after giving effect to any acquisition,
investment, sale, disposition

or similar event shall reflect on a pro forma basis such event and, to the
extent applicable, the historical earnings and cash flows associated with the
assets acquired or disposed of and any related incurrence or reduction of
Indebtedness, but shall not take into account any projected synergies or similar
benefits expected to be realized as a result of such event.

                                  The Credits

         SECTION 2.01. Term Loan and Revolving Credit Commitments. Subject to
the terms and conditions and relying upon the representations and warranties
herein set forth, each Lender agrees, severally and not jointly, (a) to make
Tranche A Term Loans to the Borrower from time to time during the Tranche A
Availability Period in an aggregate principal amount not to exceed its Tranche A
Commitment, (b) to make a Tranche B Term Loan to the Borrower on the Closing
Date in a principal amount equal to its Tranche B Commitment and (c) to make
Revolving Loans to the Borrower, at any time and from time to time during the
Revolving Credit Availability Period, in an aggregate principal amount at any
time outstanding that will not result in such Lender's Revolving Credit Exposure
exceeding such Lender's Revolving Credit Commitment. Within the limits set forth
in clause (c) of the preceding sentence and subject to the terms, conditions and
limitations set forth herein, the Borrower may borrow, pay or prepay and
reborrow Revolving Loans. Except as set forth in Section 2.24, amounts paid or
prepaid in respect of Term Loans may not be reborrowed.

         SECTION 2.02. Swingline Loans. (a) Subject to the terms and conditions
herein set forth, the Swingline Lender agrees to make Swingline Loans to the
Borrower from time to time during the Revolving Credit Availability Period in an
aggregate principal amount at any time outstanding that will not result in (i)
the aggregate principal amount of the outstanding Swingline Loans exceeding
$50,000,000 or (ii) the Aggregate Revolving Credit Exposure exceeding the Total
Revolving Credit Commitment; provided that the Swingline Lender shall not be
required to make a Swingline Loan to refinance an outstanding Swingline Loan.
Within the foregoing limits and subject to the terms and conditions set forth
herein, the Borrower may borrow, prepay and reborrow Swingline Loans.

         (ii) To request a Swingline Loan, the Borrower shall notify the
Administrative Agent of such request by telephone (confirmed by telecopy), not
later than 3:00 p.m., New York City time, on the day of a proposed Swingline
Loan. Each such notice shall be irrevocable and shall specify the requested date
(which shall be a Business Day) and amount of the requested Swingline Loan. The
Administrative Agent will promptly advise the Swingline Lender of any such
notice received from the Borrower. The Swingline Lender shall make each
Swingline Loan available to the Borrower by means of a credit to the general
deposit account of the Borrower with the Swingline Lender by 4:00 p.m., New York
City time, on the requested date of such Swingline Loan.

         (iii) The Swingline Lender may by written notice given to the
Administrative Agent not later than 11:00 a.m., New York City time, on any
Business Day require the Revolving Credit Lenders to acquire participations on
such Business Day in all or a portion of the Swingline Loans outstanding. Such
notice shall specify the aggregate amount of Swingline Loans in which Revolving
Credit Lenders will participate. Promptly upon receipt of such notice, the
Administrative Agent will give notice thereof to each Revolving Credit Lender,
specifying in such notice such Lender's Pro Rata Percentage of such Swingline
Loan or Loans. Each Revolving Credit Lender hereby absolutely and
unconditionally agrees, upon receipt of notice as provided above, to pay to the
Administrative Agent, for the account of the Swingline Lender, such Lender's Pro
Rata Percentage of such Swingline Loan or Loans. Each Revolving Credit Lender
acknowledges and agrees that its obligation to acquire participations in
Swingline Loans pursuant to this paragraph is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or Event of Default or reduction or termination of
the Revolving Credit Commitments, and that each such payment shall be made
without any offset, abatement, withholding or reduction whatsoever.
<PAGE>

                                                                              25

Each Revolving Credit Lender shall comply with its obligation under this
paragraph by wire transfer of immediately available funds, in the same manner as
provided in Section 2.03(c) with respect to Loans made by such Lender (and
Section 2.03(c) shall apply, mutatis mutandis, to the payment obligations of the
Revolving Credit Lenders), and the Administrative Agent shall promptly pay to
the Swingline Lender the amounts so received by it from the Revolving Credit
Lenders. The Administrative Agent shall notify the Borrower of any
participations in any Swingline Loan acquired pursuant to this paragraph, and
thereafter payments in respect of such Swingline Loan shall be made to the
Administrative Agent and not to the Swingline Lender. Any amounts received by
the Swingline Lender from the Borrower (or other party on behalf of the
Borrower) in respect of a Swingline Loan after receipt by the Swingline Lender
of the proceeds of a sale of participations therein shall be promptly remitted
to the Administrative Agent; any such amounts received by the Administrative
Agent shall be promptly remitted by the Administrative Agent to the Revolving
Credit Lenders that shall have made their payments pursuant to this paragraph
and to the Swingline Lender, as their interests may appear. The purchase of
participations in a Swingline Loan pursuant to this paragraph shall not relieve
the Borrower of any default in the payment thereof.

         SECTION 2.03. Loans. (a) Each Loan (other than a Swingline Loan) shall
be made as part of a Borrowing consisting of Loans made by the Lenders ratably
in accordance with their applicable Commitments; provided, that the failure of
any Lender to make any Loan shall not in itself relieve any other Lender of its
obligation to lend hereunder (it being understood, however, that no Lender shall
be responsible for the failure of any other Lender to make any Loan required to
be made by such other Lender). Except for Swingline Loans and Loans deemed made
pursuant to paragraph (f) below, the Loans comprising any Borrowing shall be in
an aggregate principal amount that is (i) an integral multiple of $1,000,000 or
(ii) equal to the remaining available balance of the applicable Commitments.
Each Swingline Loan shall be in an integral multiple of $1,000,000 and not less
than $1,000,000.

         (b) Subject to Sections 2.09 and 2.16, each Borrowing shall be
comprised entirely of ABR Loans or Eurodollar Loans as the Borrower may request
pursuant to Section 2.04. Each Swingline Loan shall be an ABR Loan. Each Lender
may at its option make any Eurodollar Loan by causing any domestic or foreign
branch or Affiliate of such Lender to make such Loan; provided that 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. Borrowings of more than one
Type may be outstanding at the same time; provided, however, that the Borrower
shall not be entitled to request any Borrowing that, if made, would result in
more than ten Eurodollar Borrowings outstanding hereunder at any time. For
purposes of the foregoing, Borrowings having different Interest Periods,
regardless of whether they commence on the same date, shall be considered
separate Borrowings.

         (c) Except with respect to Loans made pursuant to paragraph (f) below,
each Lender shall make each Loan to be made by it hereunder on the proposed date
thereof by wire transfer of immediately available funds to such account in New
York City as the Administrative Agent may designate not later than 1:00 p.m.,
New York City time; provided that Swingline Loans shall be made as provided in
Section 2.02. The Administrative Agent shall promptly transfer the amounts so
received to an account in the name of the Borrower designated by the Borrower in
the applicable Borrowing Request or, if a Borrowing shall not occur on such date
because any condition precedent herein specified shall not have been met, return
the amounts so received to the respective Lenders.

         (d) Unless the Administrative Agent shall have received notice from a
Lender prior to the date of any Borrowing that such Lender will not make
available to the Administrative Agent such Lender's portion of such Borrowing,
the Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount. If the Administrative Agent shall have so made funds
available then, to the extent that such Lender shall not have made such portion
available to the Administrative Agent, such Lender
<PAGE>

                                                                              26

and the Borrower severally agree to repay to the Administrative Agent forthwith
on demand such corresponding amount together with interest thereon for each day
from the date such amount is made available to the Borrower until the date such
amount is repaid to the Administrative Agent at (i) in the case of the Borrower,
the interest rate applicable at the time to the Loans comprising such Borrowing
and (ii) in the case of such Lender, a rate determined by the Administrative
Agent to represent its cost of overnight or short-term funds (which
determination shall be conclusive absent manifest error). If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender's Loan as part of such Borrowing for purposes of this
Agreement.

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

         (f) If an Issuing Bank shall not have received from the Borrower the
payment required to be made by Section 2.23(e) in respect of any L/C
Disbursement within the time specified in such Section, such Issuing Bank will
promptly notify the Administrative Agent of the amount of such L/C Disbursement
and the Administrative Agent will promptly notify each Revolving Credit Lender
of such amount and its Pro Rata Percentage thereof. Each Revolving Credit Lender
shall pay by wire transfer of immediately available funds to the Administrative
Agent not later than 3:00 p.m., New York City time, on such date (or, if such
Revolving Credit Lender shall have received such notice later than 1:00 p.m.,
New York City time, on any day, not later than 12:00 noon, New York City time,
on the immediately following Business Day), an amount equal to such Lender's Pro
Rata Percentage of such L/C Disbursement (it being understood that such amount
shall be deemed to constitute an ABR Revolving Loan of such Lender and such
payment shall be deemed to have reduced the L/C Exposure), and the
Administrative Agent will promptly pay to such Issuing Bank amounts so received
by it from the Revolving Credit Lenders. The Administrative Agent will promptly
pay to such Issuing Bank any amounts received by it from the Borrower pursuant
to Section 2.23(e) prior to the time that any Revolving Credit Lender makes any
payment pursuant to this paragraph (f); any such amounts received by the
Administrative Agent thereafter will be promptly remitted by the Administrative
Agent to the Revolving Credit Lenders that shall have made such payments and to
such Issuing Bank, as their interests may appear. If any Revolving Credit Lender
shall not have made its Pro Rata Percentage of such L/C Disbursement available
to the Administrative Agent as provided above, such Lender and the Borrower
severally agree to pay interest on such amount, for each day from and including
the date such amount is required to be paid in accordance with this paragraph to
but excluding the date such amount is paid, to the Administrative Agent for the
account of such Issuing Bank at (i) in the case of the Borrower, a rate per
annum equal to the interest rate applicable to ABR Revolving Loans pursuant to
Section 2.07(a), and (ii) in the case of such Lender, for the first such day,
the Federal Funds Effective Rate, and for each day thereafter, the Alternate
Base Rate.

         SECTION 2.04. Borrowing Procedure. In order to request a Borrowing
(other than a deemed Borrowing pursuant to Section 2.03(f), as to which this
Section 2.04 shall not apply), the Borrower shall hand deliver or telecopy to
the Administrative Agent a duly completed Borrowing Request (a) in the case of a
Eurodollar Borrowing, not later than 2:00 p.m., New York City time, three
Business Days before a proposed Borrowing, and (b) in the case of an ABR
Borrowing, not later than 1:00 p.m. New York City time, on the Business Day of a
proposed Borrowing. Each Borrowing Request shall be irrevocable, shall be signed
by or on behalf of the Borrower and shall specify the following information: (i)
whether the Borrowing then being requested is to be a Tranche A Term Borrowing,
a Tranche B Term Borrowing or a Revolving Credit Borrowing, and whether such
Borrowing is to be a Eurodollar Borrowing or an ABR Borrowing; (ii) the date of
such Borrowing (which shall be a Business Day), (iii) the number and location of
the account to which funds are to be disbursed; (iv) the amount of such
Borrowing; and (v) if such Borrowing is to be a Eurodollar Borrowing, the
Interest Period with respect thereto; provided, however, that, notwithstanding
any contrary specification in any Borrowing Request, each requested Borrowing
shall comply with the requirements set forth in Section 2.03. If no election as
to the Type of Borrowing is specified in any such notice, then the requested
Borrowing shall be an ABR
<PAGE>

                                                                              27

Borrowing. If no Interest Period with respect to any Eurodollar Borrowing is
specified in any such notice, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration. The Administrative Agent shall
promptly advise the applicable Lenders of any notice given pursuant to this
Section 2.04 (and the contents thereof), and of each Lender's portion of the
requested Borrowing.

         SECTION 2.05. Evidence of Debt; Repayment of Loans. (a) The Borrower
hereby unconditionally promises to pay to the Administrative Agent for the
account of each Lender (i) the then unpaid principal amount of each Revolving
Loan on the Revolving Credit Maturity Date, (ii) the principal amount of each
Term Loan of such Lender as provided in Section 2.12, and (iii) the then unpaid
principal amount of each Swingline Loan on the earlier of the Revolving Credit
Maturity Date and the first date after such Swingline Loan is made that is the
15th day or last day of a calendar month and is at least three Business Days
after such Swingline Loan is made; provided that on each date that a Revolving
Credit Borrowing is made, the Borrower shall repay all Swingline Loans then
outstanding.

         (b) Each Lender shall maintain in accordance with its usual practice an
account or accounts evidencing the indebtedness of the Borrower to such Lender
resulting from each Loan made by such Lender from time to time, including the
amounts of principal and interest payable and paid such Lender from time to time
under this Agreement.

         (c) The Administrative Agent shall maintain accounts in which it will
record (i) the amount of each Loan made hereunder, the Type thereof and the
Interest Period applicable thereto, (ii) the amount of any principal or interest
due and payable or to become due and payable from the Borrower to each Lender
hereunder and (iii) the amount of any sum received by the Administrative Agent
hereunder from the Borrower or any Guarantor and each Lender's share thereof.

         (d) The entries made in the accounts maintained pursuant to paragraphs
(b) and (c) above shall be prima facie evidence of the existence and amounts of
the obligations therein recorded; provided, however, that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligation of the Borrower to repay
the Loans in accordance with their terms.

         (e) Notwithstanding any other provision of this Agreement, in the event
any Lender shall request and receive a promissory note substantially in the form
of the Revolving Loan Note set forth in Exhibit J-1, the Tranche A Term Note set
forth in Exhibit J-2 or the Tranche B Term Note set forth in Exhibit J-3, as
applicable, payable to such Lender and its registered assigns, the interests
represented by such note shall at all times (including after any assignment of
all or part of such interests pursuant to Section 9.04) be represented by one or
more promissory notes payable to the payee named therein or its registered
assigns.

         SECTION 2.06. Fees. (a) The Borrower agrees to pay to each Lender,
through the Administrative Agent, on the last day of each calendar quarter
commencing with the first such day after the date hereof (or, if any such day
shall not be a Business Day, the next preceding Business Day), and on the date
on which the last of the Commitments of such Lender shall expire or be
terminated as provided herein (each such day being called a "Fee Payment Date"),
a commitment fee (a "Commitment Fee") equal to the Applicable Rate from time to
time on the average daily unused amount of the Commitments of such Lender during
the preceding quarter (or other period commencing with the date hereof or ending
with the date on which the last of the Commitments of such Lender shall expire
or 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 Lender shall commence to accrue on the date hereof and shall cease to
accrue on the date on which the last of the Commitments of such Lender shall
expire or be terminated as provided herein. For the purpose of computing
Commitment Fees with respect to Revolving Credit Commitments, a Revolving Credit
Commitment of a Lender shall be deemed to be used to the extent of the
outstanding Revolving Loans and L/C Exposure of such Lender (and the Swingline
Exposure of such Lender shall be disregarded for such purpose).
<PAGE>

                                                                              28

         (b) The Borrower agrees to pay to the Arranger and to the
Administrative Agent, for their own accounts, the fees separately agreed upon by
the Borrower, the Arranger and the Administrative Agent.

         (c) The Borrower agrees to pay (i) to each Revolving Credit Lender,
through the Administrative Agent, on each Fee Payment Date, a fee (an "L/C
Participation Fee") on such Lender's Pro Rata Percentage of the average daily
aggregate L/C Exposure (excluding the portion thereof attributable to
unreimbursed L/C Disbursements) during the preceding quarter (or shorter period
commencing with the date hereof or ending with the date on which all Letters of
Credit have been canceled or have expired and the Revolving Credit Commitments
of all Lenders shall have been terminated) at a rate equal to (A) in the case of
Letters of Credit that are Non-Financial Letters of Credit, 60% of the
Applicable Rate from time to time used to determine the interest rate on
Revolving Credit Borrowings comprised of Eurodollar Loans pursuant to Section
2.07 and (B) in the case of all other Letters of Credit, such Applicable Rate,
and (ii) to each Issuing Bank, (A) on each Fee Payment Date and on the date on
which the Letter of Credit Commitment of such Issuing Bank shall be terminated
as provided herein and no Letters of Credit of such Issuing Bank shall be
outstanding, a fronting fee at such rate per annum as shall be set forth in the
Issuing Bank Agreement of such Issuing Bank or as the Borrower and the Issuing
Bank may otherwise agree upon from time to time on the undrawn face amount of
each outstanding Letter of Credit of such Issuing Bank, and (B) the standard
issuance and drawing fees specified from time to time by such Issuing Bank
(collectively, the "Issuing Bank Fees"). All L/C Participation Fees and Issuing
Bank Fees shall be computed on the basis of the actual number of days elapsed in
a year of 360 days.

         (d) All Fees shall be paid on the dates due, in immediately available
funds, to the Administrative Agent for distribution, if and as appropriate,
among the Lenders, except that the Issuing Bank Fees shall be paid directly to
the Issuing Banks. Once paid, none of the Fees shall be refundable.

         SECTION 2.07. Interest on Loans. (a) Subject to the provisions of
Section 2.08, the Loans comprising each ABR Borrowing (including each Swingline
Loan) shall bear interest (computed on the basis of the actual number of days
elapsed over a year of 365 or 366 days, as the case may be, when the Alternate
Base Rate is determined by reference to the Prime Rate and over a year of 360
days at all other times) at a rate per annum equal to the Alternate Base Rate
plus the Applicable Rate in effect for such Loans from time to time.

         (b) Subject to the provisions of Section 2.08, the Loans comprising
each Eurodollar Borrowing 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 Rate in effect for such Loans from time to time.

         (c) 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 or Adjusted LIBO Rate for each Interest
Period or day within an Interest Period, as the case may be, shall be determined
by the Administrative Agent, and such determination shall be conclusive absent
manifest error.

         SECTION 2.08. 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 or under any other Loan Document, 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 to but excluding the date of actual
payment (after as well as before judgment) (a) in the case of overdue principal,
at the rate otherwise applicable to such Loan pursuant to Section 2.07 plus 2%
per annum and (b) in all other cases, at the rate per annum applicable at such
time to ABR Loans comprising Tranche B Term Borrowings plus 2% per annum.

         SECTION 2.09. Alternate Rate of Interest. 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
<PAGE>

                                                                              29

Borrowing the Administrative 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 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
Administrative Agent shall, as soon as practicable thereafter, give written or
telecopy notice of such determination to the Borrower and the Lenders. In the
event of any such determination, until the Administrative Agent shall have
advised the Borrower and the Lenders that the circumstances giving rise to such
notice no longer exist, any request by the Borrower for a Eurodollar Borrowing
pursuant to Section 2.04 or 2.11 shall be deemed to be a request for an ABR
Borrowing. Each determination by the Administrative Agent hereunder shall be
conclusive absent manifest error.

         SECTION 2.10. Termination and Reduction of Commitments. (a) Except as
set forth in Section 2.24, the Tranche A Commitments shall automatically
terminate at 5:00 p.m., New York City time, on the last day of the Tranche A
Availability Period. The Tranche B Commitments shall automatically terminate at
5:00 p.m., New York City time, on the Closing Date. The Revolving Credit
Commitments, the Swingline Commitment and the L/C Commitment shall automatically
terminate at 5:00 p.m., New York City time, on the Revolving Credit Maturity
Date. Notwithstanding the foregoing, all the Commitments shall automatically
terminate at 5:00 p.m., New York City time, on July 7, 2000, if the initial
Credit Event shall not have occurred by such time.

         (b) Upon at least three Business Days' prior irrevocable written or
telecopy notice to the Administrative Agent, the Borrower may at any time in
whole permanently terminate, or from time to time in part permanently reduce,
the Tranche A Commitments, the Tranche B Commitments or the Revolving Credit
Commitments; provided, however, that (i) each partial reduction of the Tranche A
Commitments, the Tranche B Commitments or the Revolving Credit Commitments shall
be in an integral multiple of $1,000,000 and (ii) the Total Revolving Credit
Commitment shall not be reduced to an amount that is less than the Aggregate
Revolving Credit Exposure at the time.

         (c) Each reduction in the Tranche A Commitments, the Tranche B
Commitments or the Revolving Credit Commitments (except as contemplated by
paragraph (e) below) shall be made ratably among the Lenders in accordance with
their respective applicable Commitments. The Borrower shall pay to the
Administrative Agent for the accounts of the Lenders, on the date of each
termination or reduction, the Commitment Fees due on the amount of the
Commitments so terminated or reduced accrued to but excluding the date of such
termination or reduction.

         SECTION 2.11. Conversion and Continuation of Borrowings. The Borrower
shall have the right (subject to the limitations specified in Section 2.03) at
any time upon prior irrevocable notice to the Administrative Agent (a) not later
than 2:00 p.m., New York City time, one Business Day prior to conversion, to
convert any Eurodollar Borrowing into an ABR Borrowing, (b) not later than 2:00
p.m., New York City time, three Business Days prior to conversion or
continuation, to convert any ABR Borrowing into a Eurodollar Borrowing or to
continue any Eurodollar Borrowing as a Eurodollar Borrowing for an additional
Interest Period, and (c) not later than 2:00 p.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, subject in
each case to the following:

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

                  (ii)  if less than all the outstanding principal amount of any
         Borrowing shall be converted or continued, then each resulting
         Borrowing shall satisfy the limitations specified in Sections 2.03(a)
         and (b) regarding the principal amount and maximum number of Borrowings
         of the relevant Type;
<PAGE>

                                                                              30

                  (iii)  each conversion shall be effected by each Lender and
         the Administrative Agent by recording for the account of such Lender
         the new Loan of such Lender resulting from such conversion and reducing
         the Loan (or portion thereof) of such Lender being converted by an
         equivalent principal amount; accrued interest on any Eurodollar Loan
         (or portion thereof) being converted shall be paid by the Borrower at
         the time of conversion;

                  (iv)  if any Eurodollar 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 2.17;

                  (v)    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;

                  (vi)   any portion of a Eurodollar Borrowing that cannot be
         converted into or continued as a Eurodollar Borrowing by reason of the
         immediately preceding clause shall be automatically converted at the
         end of the Interest Period in effect for such Borrowing into an ABR
         Borrowing;

                  (vii)  no Interest Period may be selected for any Tranche A
         Term Borrowing or Tranche B Term Borrowing that is a Eurodollar
         Borrowing that would end later than a Term Loan 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
         (A) the Tranche A Term Borrowings or Tranche B Term Borrowings, as the
         case may be, that are Eurodollar Borrowings with Interest Periods
         ending on or prior to such Term Loan Repayment Date and (B) the Tranche
         A Term Borrowings or Tranche B Term Borrowings, as the case may be,
         that are ABR Borrowings would not be at least equal to the principal
         amount of Tranche A Term Borrowings or Tranche B Term Borrowings to be
         paid on such Term Loan Repayment Date; and

                  (viii) upon notice to the Borrower from the Administrative
         Agent given at the request of the Required Lenders, after the
         occurrence and during the continuance of a Default or Event of Default,
         no outstanding Loan may be converted into, or continued as, a
         Eurodollar Loan. The foregoing is without prejudice to the other rights
         and remedies available hereunder upon an Event of Default.

         Each notice pursuant to this Section 2.11 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 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, 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, the
Borrower shall be deemed to have selected an Interest Period of one month's
duration. The Administrative Agent shall advise the Lenders of any notice given
pursuant to this Section 2.11 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 2.11 to continue any Borrowing into a subsequent Interest
Period (and shall not otherwise have given notice in accordance with this
Section 2.11 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. This
Section shall not apply to Swingline Loans, which may not be converted or
continued.

         SECTION 2.12. Repayment of Term Borrowings. (a) The Borrower shall pay
to the Administrative Agent, for the accounts of the Tranche A Lenders, on each
Tranche A Term Loan Repayment Date, a principal amount of the Tranche A Term
Loans equal to the percentage of the aggregate principal amount of the Tranche A
Term Loans made hereunder prior to the end of the Tranche A Availability Period
set forth below opposite the number corresponding to such

Tranche A Term Loan Repayment Date (subject to adjustment from time to time
pursuant to Sections 2.13(b) and 2.14(g)), together in each case with accrued
and unpaid interest on the principal amount to be paid to but excluding the date
of such payment:

                       9-12                     6.250%
                      13-16                     8.125%

         (b) The Borrower shall pay to the Administrative Agent, for the
accounts of the Tranche B Lenders, on each Tranche B Term Loan Repayment Date, a
principal amount of the Tranche B Term Loans equal to the percentage of the
Tranche B Term Loans made on the Closing Date set forth below opposite the
number corresponding to such Tranche B Term Loan Repayment Date (subject to
adjustment from time to time pursuant to Sections 2.13(b) and 2.14(g)), together
in each case with accrued and unpaid interest on the principal amount to be paid
to but excluding the date of such payment:

                         Tranche B Term Loan           Percentage
                         -------------------           ----------
                           Repayment Date
                           --------------
                               1-24                        0.25%
                              25-28                       23.50%

         (c) To the extent not previously paid, all Tranche A Term Loans and
Tranche B Term Loans shall be due and payable on the Tranche A Maturity Date and
Tranche B Maturity Date, respectively, together with accrued and unpaid interest
on the principal amount to be paid to but excluding the date of payment.

         (d) All repayments pursuant to this Section 2.12 shall be subject to
Section 2.17, but shall otherwise be without premium or penalty.

         SECTION 2.13. Optional Prepayments. (a) The Borrower shall have the
right at any time and from time to time to prepay any Borrowing, in whole or in
part, upon at least three Business Days' prior written or telecopy notice (or
telephone notice promptly confirmed by written or telecopy notice) to the
Administrative Agent before 12:00 noon, New York City time; provided, however,
that each partial prepayment shall be in an amount that is an integral multiple
of $1,000,000.

         (b) Optional prepayments of Term Borrowings shall be allocated ratably
between the then outstanding Tranche A Term Borrowings and Tranche B Term
Borrowings and the amounts so allocated shall be applied ratably against the
remaining scheduled installments of principal due in respect of the Tranche A
Term Borrowings and Tranche B Term Borrowings, respectively, under Section
2.12(a) and (b).

         (c) Each notice of a prepayment under this Section 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 by the amount stated therein on the date stated therein. All
prepayments of Borrowings under this Section shall be subject to Section 2.17,
but otherwise without premium or penalty. All prepayments under this Section
shall be accompanied by accrued interest on the principal amount being prepaid
to the date of payment.

                                                                              32

         SECTION 2.14. Mandatory Prepayments. (a) In the event of any
termination of all the Revolving Credit Commitments, the Borrower shall repay or
prepay all the outstanding Revolving Credit Borrowings on the date of such
termination. In the event of any partial reduction of the Revolving Credit
Commitments, then (i) at or prior to the effective date of such reduction, the
Administrative Agent shall notify the Borrower and the Revolving Credit Lenders
of the Aggregate Revolving Credit Exposure after giving effect thereto and (ii)
if the Total Revolving Credit Commitment after giving effect to such reduction
or termination would be less than the Aggregate Revolving Credit Exposure at the
time, the Borrower shall, on the date of such reduction or termination, repay or
prepay Revolving Credit Borrowings in an amount sufficient to eliminate such
deficiency.

         (b) Not later than the date 20 Business Days after the completion of
any Asset Sale (or any earlier date on which the Borrower shall have determined
not to reinvest the Net Cash Proceeds thereof as contemplated by the definition
of "Net Cash Proceeds" in Section 1.01), the Borrower shall apply 100% of the
Net Cash Proceeds received with respect thereto to prepay outstanding Term
Loans.

         (c) Not later than the Business Day following the receipt by the
Borrower or any Subsidiary of Net Cash Proceeds from any Equity Issuance, the
Borrower shall apply an amount equal to 100% of such Net Cash Proceeds to prepay
outstanding Term Loans; provided that so long as at least 75% of the Net Cash
Proceeds of any Equity Issuance shall be used to prepay Term Loans, or to prepay
Revolving Loans with the Revolving Credit Commitments being simultaneously
reduced by the amount of such prepayment, the Borrower may apply the lesser of
(1) the remaining Net Cash Proceeds of such Equity Issuance and (2) the amount
by which $75,000,000 exceeds the aggregate amount of all Net Cash Proceeds of
Equity Issuances that have previously been so applied, to prepay Revolving Loans
without any corresponding reduction of the Revolving Credit Commitments.

         (d) Not later than the earlier of (i) the date 90 days after the end of
each fiscal year of the Borrower, commencing with the fiscal year ending
November 30, 2000, and (ii) the date on which the financial statements with
respect to such fiscal year are delivered pursuant to Section 5.03(a), the
Borrower shall prepay outstanding Term Loans in an aggregate principal amount
equal to 50% of Excess Cash Flow for such fiscal year.

         (e) In the event that the Borrower or any Subsidiary shall receive Net
Cash Proceeds from the incurrence or disposition of any Indebtedness (other than
Indebtedness permitted under clauses (a) through (n) of Section 6.01), the
Borrower shall, as promptly as practicable and in any event not later than the
Business Day following the receipt of such Net Cash Proceeds, apply 100% of such
Net Cash Proceeds to prepay outstanding Term Loans; provided that if the
Borrower or any Subsidiary shall receive Net Cash Proceeds from the incurrence
or disposition of any Subordinated Indebtedness, and if the Consolidated
Leverage Ratio at the end of and for the most recent period of four fiscal
quarters for which financial statements have been delivered under Section
5.03(a) or (b), as applicable, giving pro forma effect to the incurrence or
disposition of such Subordinated Indebtedness and the application of the
proceeds thereof as if they had occurred at the beginning of such period, would
be less than 2.00 to 1.00, the Borrower shall be required to apply only 50% of
the Net Cash Proceeds of such incurrence or disposition as contemplated above.

         (f) In the event the Borrower shall receive or hold Net Cash Proceeds
from any Asset Sale, Equity Issuance or incurrence or disposition of
Indebtedness or other amounts that would, if not applied to the prepayment of
senior Indebtedness or to purchase assets, be required to be applied to prepay,
redeem, repurchase or defease any Indebtedness that is subordinated in right of
payment to any of the Obligations, and if the Borrower shall not apply such Net
Cash Proceeds to the voluntary prepayment of the Loans or to purchase assets, in
either case in such manner as to avoid the requirement that subordinated
Indebtedness be so prepaid, redeemed, repurchased or defeased, the Borrower
shall, prior to the date on which such Net Cash Proceeds or other amounts would
be required to be applied to prepay, redeem, repurchase or defease any such
subordinated Indebtedness, apply an amount equal to 100% of such Net Cash
Proceeds or such

                                                                              33

other amounts to prepay outstanding Term Loans in accordance with paragraph (i)
below or, after the Term Loans shall have been prepaid in full, to prepay
Revolving Loans or Swingline Loans or, if no such Loans are outstanding, to cash
collateralize Letters of Credit.

         (g) Mandatory prepayments of Term Loans shall, subject to paragraph (j)
below, be allocated ratably between the then outstanding Tranche A Term
Borrowings and Tranche B Term Borrowings and the amounts so allocated shall be
applied ratably against the remaining scheduled installments of principal due in
respect of the Tranche A Term Borrowings and Tranche B Term Borrowings,
respectively, under Section 2.12(a) and (b).

         (h) The Borrower shall deliver to the Administrative Agent, at the time
of each prepayment required under this Section, (i) a certificate signed by a
Financial Officer of the Borrower setting forth in reasonable detail the
calculation of the amount of such prepayment and (ii) to the extent practicable,
at least three days prior written notice of such prepayment. Each notice of
prepayment shall specify the prepayment date and the Type and principal amount
of each Loan (or portion thereof) to be prepaid. All prepayments under this
Section 2.14 shall be subject to Section 2.17, but shall otherwise be without
premium or penalty.

         (i) Amounts to be applied pursuant to this Section to the prepayment of
Loans of any class shall be applied first to reduce outstanding ABR Loans of
such class and then to prepay Eurodollar Loans of such class. In the event the
amount of any prepayment of Loans of any class required to be made pursuant to
this Section shall exceed the aggregate principal amount of the ABR Loans of
such class outstanding (the amount of any such excess being called the "Excess
Amount"), the Borrower shall have the right, in lieu of making such prepayment
in full, to prepay all the outstanding ABR Loans of such class and to deposit an
amount equal to the Excess Amount with the Collateral Agent in a cash collateral
account maintained (pursuant to documentation reasonably satisfactory to the
Administrative Agent) by and in the sole dominion and control of the Collateral
Agent. Any amounts so deposited shall be held by the Collateral Agent as
collateral for the Obligations and applied to the prepayment of the applicable
Eurodollar Loans at the ends of the current Interest Periods applicable thereto.
At the request of the Borrower, amounts so deposited shall be invested by the
Collateral Agent in Specified Investments maturing prior to the date or dates on
which it is anticipated that such amounts will be applied to prepay Eurodollar
Loans; any interest earned on such Specified Investments will be for the account
of the Borrower, and the Borrower will deposit with the Administrative Agent the
amount of any loss on any such Specified Investment to the extent necessary in
order that the amount of the prepayment to be made with the deposited amounts
may not be reduced.

         (j) Any Tranche B Lender may elect, by notice to the Administrative
Agent in writing (or by telephone or telecopy promptly confirmed in writing) at
least one Business Day prior to any prepayment of Tranche B Term Loans required
to be made by the Borrower for the account of such Lender pursuant to this
Section, to cause all or a portion of such prepayment to be applied instead to
prepay Tranche A Term Loans in accordance with paragraph (g) above (and any
prepayment or portion thereof as to which such an election is made shall be so
applied); provided that no Tranche B Lender shall be entitled to make such
election to the extent that at the time thereof the portion of the prepayment as
to which such elections are made exceeds the outstanding amount of the Tranche A
Term Loans (and the elections of Tranche B Lenders shall be reduced, ratably in
accordance with the respective amounts as to which such elections shall have
been made by the electing Tranche B Lenders, to the extent required by this
proviso).

         (k) Notwithstanding anything to the contrary set forth in this Section
2.14, no prepayment shall be required under any provision of this Section 2.14
if at the time a prepayment would otherwise be required (i) the Borrower's
senior, unsecured, non-credit-enhanced, long-term Indebtedness for borrowed
money shall be rated BBB- or better by S&P and Baa3 or better by Moody's or (ii)
the Consolidated Leverage Ratio as of the end of the most recent fiscal quarter
for which financial statements have been delivered under Section 5.03(a) or (b)
shall be less than 2.00 to 1.00.

         SECTION 2.15. Reserve Requirements; Change in Circumstances. (a)
Notwithstanding any other provision of this Agreement, if after the date of this
Agreement 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 Issuing
Bank of the principal of or interest on any Eurodollar Loan made by such Lender
or any Fees or other amounts payable hereunder (other than changes in respect of
taxes imposed on the overall net income of such Lender or Issuing Bank by the
jurisdiction in which such Lender or Issuing Bank has its principal office or
applicable 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 extended by any Lender or Issuing Bank (except any such
reserve requirement which is reflected in the Adjusted LIBO Rate) or shall
impose on such Lender or Issuing Bank or the London interbank market any other
condition affecting this Agreement or Eurodollar Loans made by such Lender or
any Letter of Credit or participation therein, and the result of any of the
foregoing shall be to increase the cost to such Lender or Issuing Bank of making
or maintaining any Eurodollar Loan or of issuing or maintaining any Letter of
Credit or purchasing or maintaining a participation therein or to reduce the
amount of any sum received or receivable by such Lender or Issuing Bank
hereunder (whether of principal, interest or otherwise) by an amount deemed by
such Lender or Issuing Bank to be material, then the Borrower will pay to such
Lender or Issuing Bank, as the case may be, upon demand such additional amount
or amounts as will compensate such Lender or Issuing Bank, as the case may be,
for such additional costs incurred or reduction suffered.

         (b) If any Lender or Issuing Bank shall have determined that the
adoption after the date hereof of any law, rule, regulation, agreement or
guideline regarding capital adequacy, or any change after the date hereof in any
such law, rule, regulation, agreement or guideline (whether such law, rule,
regulation, agreement or guideline has been adopted) or in the interpretation or
administration thereof by any Governmental Authority charged with the
interpretation or administration thereof, or compliance by any Lender (or any
lending office of such Lender) or Issuing Bank or any Lender's or Issuing Bank's
holding company with any request or directive issued after the date hereof
regarding capital adequacy (whether or not having the force of law) of any
Governmental Authority has or would have the effect of reducing the rate of
return on such Lender's or Issuing Bank's capital or on the capital of such
Lender's or Issuing Bank's holding company, if any, as a consequence of this
Agreement or the Loans made or participations in Letters of Credit purchased by
such Lender pursuant hereto or the Letters of Credit issued by such Issuing Bank
pursuant hereto to a level below that which such Lender or Issuing Bank or such
Lender's or Issuing Bank's holding company could have achieved but for such
applicability, adoption, change or compliance (taking into consideration such
Lender's or Issuing Bank's policies and the policies of such Lender's or Issuing
Bank's holding company with respect to capital adequacy) by an amount deemed by
such Lender or Issuing Bank to be material, then from time to time the Borrower
shall pay to such Lender or Issuing Bank, as the case may be, such additional
amount or amounts as will compensate such Lender or Issuing Bank or such
Lender's or Issuing Bank's holding company for any such reduction suffered.

         (c) A certificate of a Lender or Issuing Bank setting forth the amount
or amounts necessary to compensate such Lender or Issuing Bank or its holding
company, as applicable, as specified in paragraph (a) or (b), together with
supporting documentation or computations, above shall be delivered to the
Borrower and shall be conclusive absent manifest error; provided that the
Borrower shall not be required to compensate a Lender or Issuing Bank pursuant
to this Section for any increased costs or reductions incurred more than 180
days prior to the date on which such Lender or Issuing Bank notifies the
Borrower in writing of the change giving rise thereto and of its intention to
claim compensation therefor; provided further, that if the change giving rise to
such increased costs or reductions shall be retroactive, then the 180 day period
referred to above shall be extended to include the period of retroactive effect
thereof. The Borrower shall pay such Lender or Issuing Bank the amount shown as
due on any such certificate delivered by it within 10 days after its receipt of
the same.

                                                                              35

         (d) Failure or delay on the part of any Lender or Issuing Bank to
demand compensation for any increased costs or reduction in amounts received or
receivable or reduction in return on capital shall not constitute a waiver of
such Lender's or Issuing Bank's right to demand such compensation. The
protection of this Section shall be available to each Lender and Issuing Bank
regardless of any possible contention of the invalidity or inapplicability of
the law, rule, regulation, agreement, guideline or other change or condition
that shall have occurred or been imposed.

         SECTION 2.16. Change in Legality. (a) Notwithstanding any other
provision of this Agreement, if, after the date hereof, 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 Administrative Agent:

                  (i)  such Lender may declare that Eurodollar Loans will not
         thereafter (for the duration of such unlawfulness) be made by such
         Lender hereunder (or, for such duration, be continued for additional
         Interest Periods and ABR Loans will not thereafter (for such duration)
         be converted into Eurodollar Loans), whereupon any request for a
         Eurodollar Borrowing (or to convert an ABR Borrowing to a Eurodollar
         Borrowing or to continue a Eurodollar Borrowing for an additional
         Interest Period) shall, as to such Lender only, be deemed a request for
         an ABR Loan (or a request to continue an ABR Loan as such for an
         additional Interest Period or to convert a Eurodollar Loan into an ABR
         Loan, as the case may be), unless such declaration shall be
         subsequently withdrawn; and

                  (ii) such Lender may 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 that 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 2.16, a notice to the Borrower by any
Lender shall be effective as to each Eurodollar Loan made by such Lender, if
lawful, on the last day of the Interest Period currently applicable to such
Eurodollar Loan; in all other cases such notice shall be effective on the date
of receipt by the Borrower.

         SECTION 2.17. Indemnity. The Borrower shall indemnify each Lender
against any loss that such Lender may sustain or incur as a consequence of (a)
any event, other than a default by such Lender in the performance of its
obligations hereunder, which results in (i) such Lender receiving or being
deemed to receive any amount on account of the principal of any Eurodollar Loan
prior to the end of the Interest Period in effect therefor (including by reason
of any assignment pursuant to Section 2.22(a)), (ii) the conversion of any
Eurodollar Loan to an ABR Loan, or the conversion of the Interest Period with
respect to any Eurodollar Loan, in each case other than on the last day of the
Interest Period in effect therefor, or (iii) any Eurodollar Loan to be made by
such Lender (including any Eurodollar Loan to be made pursuant to a conversion
or continuation under Section 2.11) not being made after notice of such Loan
shall have been given by the Borrower hereunder (any of the events referred to
in this clause (a) being called a "Breakage Event") or (b) any default in the
making of any payment or prepayment required to be made hereunder. In the case
of any Breakage Event, such loss shall include an amount equal to the excess, as
reasonably determined by such Lender, of (i) its cost of obtaining funds for the
Eurodollar Loan that is the subject of such Breakage Event for the period from
the date of such Breakage Event to the last day of the Interest Period in effect
(or that would have been in effect) for such Loan over (ii) the amount of
interest likely to be realized by such Lender in redeploying

                                                                              36

the funds released or not utilized by reason of such Breakage Event for such
period. A certificate of any Lender setting forth any amount or amounts which
such Lender is entitled to receive pursuant to this Section 2.17, together with
supporting documentation or computations, shall be delivered to the Borrower and
shall be conclusive absent manifest error.

         SECTION 2.18. Pro Rata Treatment. Except as required under Sections
2.14 and 2.16, each Borrowing, each payment or prepayment of principal of any
Borrowing, each payment of interest on the Loans, each payment of the Commitment
Fees, each reduction of the Term Loan Commitments or the Revolving Credit
Commitments and each conversion of any Borrowing to or continuation of any
Borrowing as a Borrowing of any Type 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 outstanding Loans), and the
Borrower and the Lenders agree to take all such actions as shall be necessary to
give effect to such requirement. Each Lender agrees that in computing such
Lender's portion of any Borrowing to be made hereunder, the Administrative Agent
may, in its discretion, round each Lender's percentage of such Borrowing to the
next higher or lower whole dollar amount.

         SECTION 2.19. 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 any other Loan Party, 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 by any other
means, obtain payment, voluntary or involuntary, in respect of any Loan or Loans
or L/C Disbursement as a result of which the unpaid principal portion of its
Tranche A Term Loans, Tranche B Term Loans and Revolving Loans and
participations in L/C Disbursements and Swingline Loans shall be proportionately
less than the unpaid principal portion of the Tranche A Term Loans, Tranche B
Term Loans and Revolving Loans and participations in L/C Disbursements and
Swingline Loans of any other Lender, it shall be deemed simultaneously to have
purchased from such other Lender at face value, and shall promptly pay to such
other Lender the purchase price for, a participation in the Tranche A Term
Loans, Tranche B Term Loans, Revolving Loans or L/C Exposure or Swingline
Exposure, as the case may be, of such other Lender, so that the benefit of all
such payments shall be shared by the Lenders ratably in accordance with the
aggregate unpaid principal amount of the Tranche A Term Loans, Tranche B Term
Loans and Revolving Loans and L/C Exposure and Swingline Exposure and
participations in Tranche A Term Loans, Tranche B Term Loans, Revolving Loans
and L/C Exposure and Swingline Exposure held by the Lenders; provided, however,
that (i) if any such participations are purchased pursuant to this Section and
the payment giving rise thereto shall thereafter be recovered, such
participations shall be rescinded to the extent of such recovery and the
purchase price restored without interest, and (ii) the provisions of this
paragraph shall not be construed to apply to any payment made by the Borrower
pursuant to and in accordance with the express terms of this Agreement or any
payment obtained by a Lender as consideration for the assignment of or sale of a
participation in any of its Loans or participations in L/C Disbursements or
Swingline Loans to any assignee or participant, other than to the Borrower or
any of the Subsidiaries or any Affiliate thereof (as to which the provisions of
this paragraph shall apply). The Borrower expressly consents to the foregoing
arrangements and agrees that any Lender holding a participation in a Term Loan,
Revolving Loan, L/C Disbursement or Swingline Loan 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 of such participation as fully as if such Lender had made a
Loan directly to the Borrower in the amount of such participation.

         SECTION 2.20. Payments. (a) The Borrower shall make each payment
(including principal of or interest on any Borrowing or any L/C Disbursement or
any Fees or other amounts) hereunder and under any other Loan Document not later
than 1:00 p.m., New York City time, on the date when due in immediately
available dollars, without setoff, defense or counterclaim. Any amounts received
after such time on any date may, in the discretion of the Administrative Agent,
be deemed to have been received on the next succeeding Business Day for purposes
of calculating interest thereon. Each such payment (other than (i) payments to
be made directly to
<PAGE>

                                                                              37

the Issuing Banks or the Swingline Lender as expressly provided herein and (ii)
payments pursuant to Sections 2.15, 2.17, 2.21 and 9.05 or pursuant to other
Loan Documents, which shall be made directly to the persons entitled thereto)
shall be made to the Administrative Agent at its offices at Eleven Madison
Avenue, New York, New York 10010, or as otherwise directed.

     (b)  The Administrative Agent shall distribute any such payments received
by it for the account of any other person to the appropriate recipient promptly
following receipt thereof. 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.

     (c)  If at any time insufficient funds are received by and available to the
Administrative Agent to pay fully all amounts of principal, unreimbursed L/C
Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably
among the parties entitled thereto in accordance with the amounts of interest
and fees then due to such parties, and (ii) second, towards payment of principal
and unreimbursed L/C Disbursements then due hereunder, ratably among the parties
entitled thereto in accordance with the amounts of principal and unreimbursed
L/C Disbursements then due to such parties.

     SECTION 2.21.  Taxes.  (a)  Any and all payments by or on account of any
obligation of the Borrower hereunder shall be made free and clear of and without
deduction for any Indemnified Taxes or Other Taxes; provided that if the
Borrower shall be required to deduct any Indemnified Taxes or Other Taxes from
such payments, then (i) the sum payable shall be increased as necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section) the Administrative Agent, Lender or
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 Governmental Authority in accordance with applicable law.

     (b)  In addition, the Borrower shall pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

     (c)  The Borrower shall indemnify the Administrative Agent, each Lender and
each Issuing Bank, within 30 days after written demand therefor, for the full
amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent,
such Lender or such Issuing Bank, as the case may be, on or with respect to any
payment by or on account of any obligation of the Borrower hereunder (including
Indemnified Taxes or Other Taxes imposed or asserted on or attributable to
amounts payable under this Section) and any penalties, interest and reasonable
expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted
by the relevant Governmental Authority provided that the Borrower shall not be
required to compensate a Lender or Issuing Bank pursuant to this Section for any
Indemnified Taxes or Other Taxes incurred more than 180 days prior to the date
on which such Lender or Issuing Bank notifies the Borrower in writing of the
change giving rise thereto and of its intention to claim compensation therefor;
provided further, that if the change giving rise to such Indemnified Taxes or
Other Taxes shall be retroactive, then the 180 day period referred to above
shall be extended to include the period of retroactive effect thereof. A
certificate as to the amount of such payment or liability delivered to the
Borrower by a Lender or Issuing Bank, or by the Administrative Agent on its own
behalf or on behalf of a Lender or Issuing Bank, shall be conclusive absent
manifest error.

     (d)  As soon as practicable after any payment of Indemnified Taxes or Other
Taxes by the Borrower to a Governmental Authority, the Borrower shall deliver to
the Administrative Agent the original or a certified copy of a receipt issued by
such Governmental Authority
<PAGE>

                                                                              38

evidencing such payment, a copy of the return reporting such payment or other
evidence of such payment reasonably satisfactory to the Administrative Agent.

     (e)  Any Foreign Lender that is entitled to an exemption from or reduction
of withholding tax under the law of the jurisdiction in which the Borrower is
located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate.

     SECTION 2.22.  Assignment of Commitments Under Certain Circumstances; Duty
to Mitigate. (a) In the event (i) any Lender or Issuing Bank delivers a
certificate requesting compensation pursuant to Section 2.15, (ii) any Lender or
Issuing Bank delivers a notice described in Section 2.16, (iii) the Borrower is
required to pay any amount to any Lender or Issuing Bank or any Governmental
Authority on account of any Lender or Issuing Bank pursuant to Section 2.21 or
(iv) any Lender shall have declined, or shall be deemed to have declined, to
extend its Revolving Credit Commitment pursuant to Section 2.10(d), the Borrower
may, at its sole expense and effort (including with respect to the processing
and recordation fee referred to in Section 9.04(b)), upon notice to such Lender
or Issuing Bank and the Administrative Agent, require such Lender or Issuing
Bank to transfer and assign, without recourse (in accordance with and subject to
the restrictions contained in Section 9.04), all of its interests, rights and
obligations under this Agreement to an assignee designated by the Borrower that
shall assume such assigned obligations (which assignee may be another Lender, if
a Lender accepts such assignment); provided that (w) such assignment will result
in a reduction in the claim for compensation under Section 2.15 or in the
withdrawal of the notice under Section 2.16 or in the reduction of payments
under Section 2.21, as the case may be, (x) such assignment shall not conflict
with any law, rule or regulation or order of any court or other Governmental
Authority having jurisdiction, (y) the Borrower shall have received the prior
written consent of the Administrative Agent (and, if a Revolving Credit
Commitment is being assigned, of each Issuing Bank and the Swingline Lender),
which consent shall not unreasonably be withheld, and (z) the Borrower or such
assignee shall have paid to the affected Lender or Issuing Bank in immediately
available funds an amount equal to the sum of the principal of and interest
accrued to the date of such payment on the outstanding Loans or L/C
Disbursements of such Lender or Issuing Bank, respectively, plus all Fees and
other amounts accrued for the account of such Lender or Issuing Bank hereunder
(including any amounts under Section 2.15 and Section 2.21); provided further
that, if prior to any such transfer and assignment the circumstances or event
that resulted in such Lender's or Issuing Bank's claim for compensation under
Section 2.15 or notice under Section 2.16 or the amounts paid pursuant to
Section 2.21, as the case may be, cease to cause such Lender or Issuing Bank to
suffer increased costs or reductions in amounts received or receivable or
reduction in return on capital, or cease to have the consequences specified in
Section 2.16, or cease to result in amounts being payable under Section 2.21, as
the case may be (including as a result of any action taken by such Lender or
Issuing Bank pursuant to paragraph (b) below), or if such Lender or Issuing Bank
shall waive its right to claim further compensation under Section 2.15 in
respect of such circumstances or event or shall withdraw its notice under
Section 2.16 or shall waive its right to further payments under Section 2.21 in
respect of such circumstances or event, as the case may be, then such Lender or
Issuing Bank shall not thereafter be required to make any such transfer and
assignment hereunder.

     (b)  If (i) any Lender or Issuing Bank requests compensation under Section
2.15, (ii) any Lender or Issuing Bank delivers a notice described in Section
2.16 or (iii) the Borrower is required to pay any amount to any Lender or
Issuing Bank or any Governmental Authority on account of any Lender or Issuing
Bank pursuant to Section 2.21, then such Lender or Issuing Bank shall use
reasonable efforts (which shall not require such Lender or Issuing Bank to incur
an unreimbursed loss or unreimbursed cost or expense or otherwise take any
action materially inconsistent with its internal policies or legal or regulatory
restrictions or suffer any disadvantage or burden deemed by it to be
significant) (x) to file any certificate or document reasonably requested in
writing by the Borrower or (y) to assign its rights and delegate and transfer
its
<PAGE>

                                                                              39

obligations hereunder to another of its offices, branches or affiliates, if such
filing or assignment would reduce its claims for compensation under Section 2.15
or enable it to withdraw its notice pursuant to Section 2.16 or would reduce
amounts payable pursuant to Section 2.21, as the case may be, in the future. The
Borrower hereby agrees to pay all reasonable costs and expenses incurred by any
Lender or Issuing Bank in connection with any such filing or assignment,
delegation and transfer.

     SECTION 2.23.  Letters of Credit. (a) General. The Borrower may request the
Issuing Banks to issue Letters of Credit for its own account, at any time and
from time to time while the Revolving Credit Commitments remain in effect (but
not after the date that is five Business Days prior to the Revolving Credit
Maturity Date), to support obligations (other than trade payables) incurred by
the Borrower and the Subsidiaries in the ordinary course of their businesses.
Each Letter of Credit will be in a form reasonably acceptable to the
Administrative Agent and the applicable Issuing Bank. The Borrower shall not
request the issuance of, and this Section shall not be construed to impose an
obligation upon any Issuing Bank to issue, any Letter of Credit (i) that is
inconsistent with the terms and conditions of this Agreement or (ii) that would
result in (A) an Issuing Bank having Letters of Credit in an aggregate amount at
any time outstanding in excess of such Issuing Bank's L/C Commitment, (B) the
aggregate amount of the Letters of Credit at any time outstanding exceeding the
aggregate L/C Commitment or (C) the aggregate Revolving Credit Exposures
exceeding the Total Revolving Credit Commitment. The provisions of this Section
shall apply equally to Letters of Credit issued hereunder and to the Existing
Letters of Credit.

     (b)  Notice of Issuance; Certain Conditions. In order to request the
issuance of a Letter of Credit, the Borrower shall hand deliver or telecopy to
an Issuing Bank and the Administrative Agent (reasonably in advance of the
requested date of issuance) a notice requesting the issuance of a Letter of
Credit and setting forth the date of issuance, the date on which such Letter of
Credit is to expire (which shall comply with paragraph (c) below), the amount of
such Letter of Credit, the name and address of the beneficiary thereof and such
other information as shall be necessary to prepare such Letter of Credit. Each
Issuing Bank shall promptly (i) notify the Administrative Agent of the amount
and expiry date of each Letter of Credit issued by it and (ii) provide a copy of
each such Letter of Credit to the Administrative Agent.

     (c)  Expiration Date. Each Letter of Credit that is a Non-Financial Letter
of Credit shall expire not later than the close of business on the date that is
five Business Days prior to the Revolving Credit Maturity Date; provided that
                                                                --------
there shall not be outstanding at any date more than $250,000,000 in aggregate
stated amount of Non-Financial Letters of Credit expiring more than three years
after such date. Each Letter of Credit other than a Non-Financial Letter of
Credit shall expire not later than the close of business on the earlier of the
date one year after the date of the issuance of such Letter of Credit and the
date that is five Business Days prior to the Revolving Credit Maturity Date.

     (d)  Participations. By the issuance of a Letter of Credit and without any
further action on the part of the applicable Issuing Bank or the Lenders, such
Issuing Bank hereby grants to each Revolving Credit Lender, and each such Lender
hereby acquires from such Issuing Bank, a participation in such Letter of Credit
equal to such Lender's Pro Rata Percentage of the aggregate amount available to
be drawn under such Letter of Credit, effective upon the issuance of such Letter
of Credit. In consideration and in furtherance of the foregoing, each Revolving
Credit Lender hereby irrevocably, absolutely and unconditionally agrees to pay
to the Administrative Agent, for the account of such Issuing Bank, promptly
after the receipt of a demand from such Issuing Bank, such Lender's Pro Rata
Percentage of each L/C Disbursement made by such Issuing Bank and not reimbursed
by the Borrower forthwith on the date due, all as provided in Section 2.03(f).
Each Revolving Credit Lender acknowledges and agrees that its obligation to
acquire participations pursuant to this paragraph in respect of Letters of
Credit is irrevocable, absolute and unconditional and shall not be affected by
any circumstance whatsoever, including the occurrence and continuance of a
Default or an Event of Default or the termination of the Revolving Credit
Commitments, and that each such payment shall be made without any offset,
abatement, withholding or reduction whatsoever.
<PAGE>

                                                                              40

     (e)  Reimbursement. If an Issuing Bank shall make any L/C Disbursement in
respect of a Letter of Credit, such Issuing Bank will promptly notify the
Administrative Agent and the Borrower of the details thereof, and the Borrower
shall pay to the Administrative Agent an amount equal to such L/C Disbursement
not later than 10:00 a.m., New York City time, on the Business Day immediately
following the Business Day on which the Borrower shall have received notice from
such Issuing Bank that payment of such draft has been or will be made.

     (f)  Obligations Absolute. The Borrower's obligations to reimburse L/C
Disbursements as provided in paragraph (e) above shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement, under any and all circumstances whatsoever,
and irrespective of:

               (i)   any lack of validity or enforceability of any Letter of
     Credit or any Loan Document, or any term or provision therein;

               (ii)  any amendment or waiver of or any consent to departure from
     all or any of the provisions of any Letter of Credit or any Loan Document;

               (iii) the existence of any claim, setoff, defense or other right
     that the Borrower, any other party guaranteeing, or otherwise obligated
     with, the Borrower, any Subsidiary or other Affiliate thereof or any other
     person may at any time have against the beneficiary under any Letter of
     Credit, such Issuing Bank, the Administrative Agent or any Lender or any
     other person, whether in connection with this Agreement, any other Loan
     Document or any other related or unrelated agreement or transaction;

               (iv)  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;

               (v)   payment by such Issuing Bank under a Letter of Credit
     against presentation of a draft or other document that does not comply with
     the terms of such Letter of Credit; and

               (vi)  any other act, or omission to act, or delay of any kind of
     such Issuing Bank, the Lenders, the Administrative Agent or any other
     person or any other event or circumstance whatsoever, whether or not
     similar to any of the foregoing, that might, but for the provisions of this
     Section, constitute a legal or equitable discharge of the Borrower's
     obligations hereunder.

     Without limiting the generality of the foregoing, it is expressly
understood and agreed that the absolute and unconditional obligation of the
Borrower hereunder to reimburse L/C Disbursements will not be excused by the
gross negligence or wilful misconduct of the Issuing Bank. However, the
foregoing shall not be construed to excuse the Issuing Bank from liability to
the Borrower to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by the Borrower to the
extent permitted by applicable law) suffered by the Borrower that are caused by
the Issuing Bank's gross negligence or wilful misconduct in determining whether
drafts and other documents presented under a Letter of Credit comply with the
terms thereof; it is understood that the Issuing Bank may accept documents that
appear on their face to be in substantial compliance with the terms of a Letter
of Credit, without responsibility for further investigation, and make payment
under such Letter of Credit, unless, in the Issuing Bank's judgment, it has
received information that proves any such documents to be forged or fraudulent;
provided that the Issuing Bank shall not be liable in any respect for any error
made as a result of, or damages resulting from, the exercise of its judgment
with regard to any such documents if such judgment is made in good faith. The
parties hereto expressly agree that (i) 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 thereunder equals the amount of such draft and whether or not any
document
<PAGE>

                                                                              41

presented pursuant to such Letter of Credit proves to be insufficient in any
respect, if such document on its face appears to be in substantial compliance
with the terms of a Letter of Credit, and whether or not any other statement or
any other document presented pursuant to such Letter of Credit proves to be
forged, fraudulent or invalid or any statement therein proves to be inaccurate
or untrue in any respect whatsoever and (ii) any noncompliance in any immaterial
respect of the documents presented under such Letter of Credit with the terms
thereof shall, in each case, be deemed not to constitute wilful misconduct or
gross negligence of the Issuing Bank.

     (g)  Disbursement Procedures. The applicable Issuing Bank shall, promptly
following its receipt thereof, examine all documents purporting to represent a
demand for payment under a Letter of Credit. Such Issuing Bank shall as promptly
as possible give telephonic notification, confirmed by telecopy, to the
Administrative Agent and the Borrower of such demand for payment and whether
such Issuing Bank has made or will make an L/C Disbursement thereunder; provided
that any failure to give or delay in giving such notice shall not relieve the
Borrower of its obligation to reimburse such Issuing Bank and the Revolving
Credit Lenders with respect to any such L/C Disbursement. The Administrative
Agent shall promptly give each Revolving Credit Lender notice thereof.

     (h)  Interim Interest. If an Issuing Bank shall make any L/C Disbursement
in respect of a Letter of Credit, then the unpaid amount thereof shall bear
interest for the account of such Issuing Bank, for each day from and including
the date of such L/C Disbursement, to but excluding the earlier of the date of
payment by the Borrower or the date on which interest shall commence to accrue
on the related ABR Loans deemed made pursuant to Section 2.03(f), at the rate
per annum that would apply to such amount if such amount were an ABR Loan.

     (i)  Cash Collateralization. If any Event of Default shall occur and be
continuing, the Borrower shall, on the Business Day it receives notice from the
Administrative Agent or the Required Lenders (or, if the maturity of the Loans
has been accelerated, Revolving Credit Lenders holding participations in
outstanding Letters of Credit representing greater than 50% of the aggregate
undrawn amount of all outstanding Letters of Credit) thereof and of the amount
to be deposited, deposit in an account with the Collateral Agent, for the
benefit of the Revolving Credit Lenders, an amount in cash equal to the L/C
Exposure as of such date. Such deposit shall be held by the Collateral Agent as
collateral for the payment and performance of the Obligations. The Collateral
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 Specified Investments, which investments shall be
made by the Collateral Agent if in its judgment such deposits will not be
required for distribution to the Lenders or Issuing Banks hereunder prior to the
maturity of such investments (and any losses on which investments shall be for
the account of the Borrower), such deposits shall not bear interest. Interest or
profits, if any, on such investments shall accumulate in such account. Moneys in
such account shall (i) automatically be applied by the Administrative Agent to
reimburse the Issuing Banks for L/C Disbursements for which they have not been
reimbursed, (ii) be held for the satisfaction of the reimbursement obligations
of the Borrower for the L/C Exposure at such time and (iii) if the maturity of
the Loans has been accelerated (but subject to the consent of Revolving Credit
Lenders holding participations in outstanding Letters of Credit representing
greater than 50% of the aggregate undrawn amount of all outstanding Letters of
Credit), be applied to satisfy the other Obligations. If the Borrower is
required to provide an amount of cash collateral hereunder as a result of the
occurrence of an Event of Default, such amount (to the extent not applied as
aforesaid) shall be returned to the Borrower within three Business Days after
all Events of Default have been cured or waived.

     (j)  Resignation or Removal of Issuing Banks. An Issuing Bank may resign at
any time by giving 90 days' prior written notice to the Administrative Agent,
the Lenders and the Borrower, and may be removed at any time by the Borrower by
notice to such Issuing Bank, the Administrative Agent and the Lenders. At the
time such removal or resignation shall become effective, the Borrower shall pay
all fees accrued for the account of such Issuing Bank pursuant to Section
2.06(c)(ii) and not yet paid fees. After the resignation or removal of an
Issuing Bank
<PAGE>

                                                                              42

hereunder, the retiring Issuing Bank shall remain a party hereto and shall
continue to have all the rights and obligations of an Issuing Bank under this
Agreement and the other Loan Documents with respect to Letters of Credit issued
by it prior to such resignation or removal, but shall not be required to issue
additional Letters of Credit.

     (k)  Designation of Additional Issuing Banks. From time to time, the
Borrower may by notice to the Administrative Agent and the Lenders designate one
or more Lenders as additional Issuing Banks. The acceptance by a Lender of any
appointment as an Issuing Bank hereunder shall be evidenced by an agreement (an
"Issuing Bank Agreement"), which shall be in a form satisfactory to the Borrower
and the Administrative Agent, shall set forth the L/C Commitment and Issuing
Bank Fees of such Lender and shall be executed by such Lender, the Borrower and
the Administrative Agent and, from and after the effective date of such
agreement, (i) such Lender shall have all the rights and obligations of an
Issuing Bank under this Agreement and the other Loan Documents and (ii)
references herein and in the other Loan Documents to the term "Issuing Bank"
shall be deemed to include such Lender in its capacity as an Issuing Bank.

     SECTION 2.24.  Increase in Commitments. (a) If the Borrower shall have
terminated all or a portion of the Tranche A Commitments and repaid all or a
portion of the outstanding Tranche A Term Loans prior to or simultaneously with
the consummation of any Commitment increase pursuant to this Section, the
Borrower may, by written notice to the Administrative Agent executed by the
Borrower and one or more banks or other financial institutions (any such bank or
other financial institution referred to in this clause (a) being called an
"Augmenting Lender"), which may include any Lender, (i) at any time during the
Tranche A Availability Period, cause the Tranche A Commitments of the Augmenting
Lenders to be increased (or cause Tranche A Commitments to be extended by the
Augmenting Lenders, as the case may be) and/or (ii) at any time prior to the
Revolving Credit Maturity Date, cause the Revolving Credit Commitments of the
Augmenting Lenders to be increased (or cause Revolving Credit Commitments to be
extended by the Augmenting Lenders, as the case may be), in each case in an
amount for each Augmenting Lender set forth in such notice and not less than
$5,000,000; provided, that the total amount by which the Commitments may be
            --------
increased pursuant to this Section shall be limited to the aggregate amount by
which the Tranche A Commitments shall have been reduced and the Tranche A Term
Loans repaid; provided further, that each Augmenting Lender, if not already a
              -------- -------
Lender hereunder, shall be subject to the approval of the Administrative Agent
(which approval shall not be unreasonably withheld) and each Augmenting Lender
shall execute all such documentation as the Administrative Agent shall specify
to evidence its Commitment and its status as a Lender hereunder. Increases and
new Commitments created pursuant to this clause (a) shall become effective on
the date specified in the notice delivered pursuant to this paragraph. Each
existing Lender whose Commitment is not increased pursuant to this Section is
hereby referred to as a "Non-Increasing Lender". Notwithstanding the foregoing,
no increase in the total Commitments (or in the Commitment of any Lender) shall
become effective under this paragraph unless, (i) on the date of such increase,
the conditions set forth in Section 4.01 shall be satisfied (with all references
in such paragraphs to a Credit Event being deemed to be references to such
increase) and the Administrative Agent shall have received a certificate to that
effect dated such date and executed by a Financial Officer of the Borrower, and
(ii) the Administrative Agent shall have received (with sufficient copies for
each of the Lenders) documents consistent with those delivered on the Closing
Date under clauses (a) and (b) of Section 4.02 as to the corporate power and
authority of the Borrower to borrow hereunder after giving effect to such
increase.

     (b)  On the effective date (the "Increase Effective Date") of any increase
in the Tranche A Commitments or the Revolving Credit Commitments pursuant to
paragraph (a) above (a "Commitment Increase"), (i) the aggregate principal
amount of the Tranche A Term Loans or Revolving Loans, as the case may be,
outstanding (the "Initial
<PAGE>

                                                                              43

Loans") immediately prior to giving effect to the Commitment Increase on the
Increase Effective Date shall be deemed to be paid, (ii) each Augmenting Lender
that shall have been a Lender prior to the Commitment Increase shall pay to the
Administrative Agent in same day funds an amount equal to the difference between
(A) the product of (1) such Tranche A Term Lender's Applicable Percentage
(calculated after giving effect to the Commitment Increase) multiplied by (2)
the amount of the Subsequent Borrowings (as hereinafter defined) and (B) the

delivered to the Lenders (i) consolidated balance sheets and statements of
operations, stockholders' equity and cash flows of the Borrower (A) as of the
end of and for each fiscal year in the three-fiscal-year period ended December
3, 1999, audited by PricewaterhouseCoopers LLP, independent public accountants,
(B) as of the end of and for the fiscal quarter ended March 3, 2000, certified
by a Financial Officer of the Borrower, and (C) as of the end of and for each

<PAGE>

                                                                              45

Borrower and its consolidated subsidiaries and, to the best knowledge of the
Borrower, the Acquired Business as of such dates and for such periods. Such
balance sheets and the notes thereto disclose all material liabilities, direct
or contingent, of the Borrower and its consolidated subsidiaries and, to the
best knowledge of the Borrower, the Acquired Business as of the dates thereof.
Such financial statements were prepared in accordance with GAAP applied on a
consistent basis.

     (b)  The Borrower has heretofore delivered to the Lenders (i) its unaudited
pro forma combined consolidated statement of operations for the 12-month period
ended March 3, 2000, and (ii) its unaudited pro forma combined consolidated
balance sheet as of March 3, 2000, in each case based on the Borrower's
financial statements as of the end of and for the period of four fiscal quarters

Business for the four quarter period ended April 4, 2000 and prepared giving
effect to the Closing Date Transactions as if they had occurred on each such
date and at the beginning of each such period. Such financial statements (i)
(other than the financial statements with respect to the Acquired Business) have
been prepared in good faith by the Borrower and its subsidiaries, based on the
assumptions used to prepare the pro forma financial information contained in the
Confidential Information Memorandum (which assumptions are believed by the
Borrower and its subsidiaries to be reasonable), (ii) are based on the best
information available to the Borrower and its subsidiaries as of the date of
delivery thereof, and (iii) accurately reflect all adjustments required to be
made to give effect to the Closing Date Transactions, and present fairly on a
pro forma basis the consolidated financial condition and results of operations
of the Borrower, its consolidated subsidiaries and to the best knowledge of the
Borrower, the Acquired Business, as of the dates and for the periods set forth
therein, assuming that the Closing Date Transactions had actually occurred at
such dates and at the beginnings of such periods.

     (c)  All financial statements, historical or pro forma, referred to in
paragraphs (a) and (b) above have been prepared in accordance with GAAP and
comply with the requirements of Regulation S-X of the Securities and Exchange
Commission for inclusion in a registration statement for a public offering
registered under the Securities Act of 1933 and may include adjustments in
compliance with such Regulation S-X that will be duly footnoted and are
reasonably acceptable to the Administrative Agent.

     SECTION 3.06.  No Material Adverse Change. Since March 3, 2000, there has
occurred or become known to the Borrower no event, condition or change in or
affecting the Borrower and its subsidiaries, and since March 31, 2000, there has
occurred or become known to the Borrower no event, condition or change in or
affecting the Acquired Business, that, individually or in the aggregate with
other such events, conditions or changes, has had or could reasonably be
expected to have a Material Adverse Effect.

     SECTION 3.07.  Title to Properties; Possession Under Leases. (a) The
Borrower and each of the Subsidiaries has good and marketable title to, or valid
leasehold interests in, all its material properties and assets (including the
Collateral and Mortgaged Properties), except for minor defects in title that do
not interfere with its ability to conduct its business as currently conducted or
to utilize such properties and assets for their intended purposes. All such
material properties and assets are free and clear of Liens, other than Liens
expressly permitted by Section 6.02, and no material portion of any Mortgaged
Property is subject to any lease, license, sublease or other agreement granting
to any person any right to use, occupy or enjoy the same, except as set forth on
Schedule 3.07(a).

     (b)  The Borrower and each Subsidiary has complied with all material
obligations under all material leases to which it is a party and all such leases
are in full force and effect and the Borrower and each Subsidiary enjoys
peaceful and undisturbed possession under all such material leases to which it
is a party.

     (c)  The Borrower has not received any notice of, and has no knowledge of,
any pending or contemplated condemnation proceeding affecting any Mortgaged
Property or any sale or disposition thereof in lieu of condemnation.
<PAGE>

                                                                              46

of first refusal, option or other contractual right to sell, assign or otherwise
dispose of any Mortgaged Property or any interest therein.

     SECTION 3.08.  Subsidiaries. Schedule 3.08 sets forth as of the Closing
Date, after giving effect to the Acquisition, a list of all Subsidiaries,
setting forth for each Subsidiary the jurisdiction of its organization, a
description of each class of its Equity Interests and the ownership interest of
the Borrower and each other Subsidiary therein. The Equity Interests so
indicated on Schedule 3.08 are fully paid and non-assessable and are owned by
the persons indicated on such Schedule, free and clear of all Liens, other than
those created under the Security Documents.

     SECTION 3.09.  Litigation; Compliance with Laws. (a) Except as set forth on
Schedule 3.09, 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 affecting the Borrower, the
Acquired Business or any of the Subsidiaries or any business, property or rights
of any such person (i) that involve any Loan Document or the Transactions or
(ii) as to which there is a reasonable possibility of an adverse determination
and that, if adversely determined, could reasonably be expected, individually or
in the aggregate, to result in a Material Adverse Effect.

     (b)  The Borrower and each Subsidiary is in compliance with all laws,
regulations, consent decrees and orders of any Governmental Authority applicable
to it or its property and all indentures, agreements and other instruments
binding upon it or its property, except where the failure to comply,
individually or in the aggregate, could not reasonably be expected to result in
a Material Adverse Effect. No Default or Event of Default has occurred and is
continuing.

     SECTION 3.10.  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 3.11.  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 buying or
carrying Margin Stock.

     (b)  No part of the proceeds of any Loan or any Letter of Credit will be
used, whether directly or indirectly, and whether immediately, incidentally or
ultimately, for any purpose that entails a violation of the provisions of the
regulations of the Board, including Regulation U or X. The Borrower and the
Subsidiaries will at no time acquire or hold any Margin Stock that is required
under the terms of this Agreement to be pledged to the Collateral Agent unless
the Borrower shall have delivered to the Administrative Agent evidence
(including, if the Administrative Agent shall so request, a duly completed and
executed Form FRU-1) demonstrating to the satisfaction of the Administrative
Agent that the credit extended hereunder will not violate Regulation U.

     SECTION 3.12.  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 subject to regulation under, the Investment Company Act of

the Public Utility Holding Company Act of 1935.

     SECTION 3.13.  Use of Proceeds. The proceeds of the Loans and the Letters
of Credit will be used only for the purposes specified in the preamble to this
Agreement.

     SECTION 3.14.  Tax Returns. The Borrower and each Subsidiary has timely
filed or caused to be filed all Federal, state, local and foreign income tax
returns and all other material Federal, state, local and foreign tax returns
required to have been filed by it and has paid or
<PAGE>

                                                                              47

caused to be paid all taxes due and payable by it and all assessments received
by it, except taxes that are being contested in good faith by appropriate
proceedings and for which the Borrower or such Subsidiary, as applicable, shall
have set aside on its books adequate reserves.

     SECTION 3.15.  No Material Misstatements. None of (a) the Confidential
Information Memorandum or (b) any other financial statement, certificate or
other written information furnished by or on behalf of the Borrower or the
Subsidiaries to the Administrative Agent (in its capacity as such) or its
Affiliates or any Lender in connection with the negotiation of any Loan Document
or included therein or delivered pursuant thereto, in each case as supplemented
by the Borrower or any Subsidiary, contained, contains or will contain any
material misstatement of fact or omitted, omits or will omit to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were, are or will be made, not misleading;
provided that to the extent any such financial statement, certificate or other
written information was based upon or constituted a forecast or projection, the
Borrower represents only that it acted in good faith and utilized reasonable
assumptions and due care in the preparation of such information, report,
financial statement, exhibit or schedule; provided further that to the extent
any financial statement, certificate or other written information referred to
above consists of or was prepared in reliance on information furnished by the
Seller, the foregoing representation is made only to the best knowledge of the
Borrower.

     SECTION 3.16.  Employee Benefit Plans. Each of the Borrower and each ERISA
Affiliate is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder, except for any such noncompliance which could not
reasonably be expected to result in a Material Adverse Effect. No ERISA Event
has occurred or is reasonably expected to occur that, when taken together with
all other ERISA Events, could reasonably be expected to result in a Material
Adverse Effect. As of the Closing Date, the actuarial present value of all
benefit liabilities under each Plan (based on those actuarial assumptions used
to fund such Plan) did not, as of the last annual valuation date applicable
thereto for which a valuation is available, exceed the fair market value of the
assets of such Plan by more than $15,000,000, and the present value of all
benefit liabilities of all underfunded Plans (based on those actuarial
assumptions used to fund each such Plan) did not, as of the last annual
valuation dates applicable thereto for which a valuation is available, exceed
the fair market value of the assets of all such underfunded Plans by more than
$35,000,000.

     SECTION 3.17.  Environmental Matters. Except as set forth in the Borrower's
Annual Report on Form 10-K for the fiscal year ended December 3, 1999 or its
Quarterly Report on Form 10-Q for the fiscal quarter ended March 3, 2000, or
Raytheon's Annual Report on Form 10-K for the fiscal year ended December 31,
1999, or its Quarterly Report on Form 10-Q for the fiscal quarter ended March
31, 2000, or on Schedule 3.17:

     (a)  The properties owned, leased or operated (other than with respect to
the performance of Remedial Actions in the ordinary course of business) by the
Borrower and the Subsidiaries (the "Properties") do not contain any Hazardous
Materials in amounts or concentrations which (i) constitute a violation of, (ii)
require Remedial Action under, or (iii) could reasonably be expected to give
rise to liability under, Environmental Laws, which violations, Remedial Actions
and liabilities, in the aggregate, could reasonably be expected to result in a
Material Adverse Effect;

     (b)  The Properties and all operations of the Borrower and the Subsidiaries
are in compliance, and in the last five years have been in compliance, with all
Environmental Laws and all necessary Environmental Permits have been obtained
and are in effect, except to the extent that such non-compliance or failure to
obtain any necessary permits, in the aggregate, could not reasonably be expected
to result in a Material Adverse Effect;

     (c)  There have been no Releases or threatened Releases at, from, under or
proximate to the Properties or otherwise in connection with the operations of
the Borrower or the Subsidiaries, which Releases or threatened Releases, in the
aggregate, could reasonably be expected to result in a Material Adverse Effect;
<PAGE>

                                                                              48

     (d)  Neither the Borrower nor any of the Subsidiaries has received any
notice of an Environmental Claim in connection with the Properties or the
operations of the Borrower or the Subsidiaries or with regard to any person
whose liabilities for environmental matters the Borrower or the Subsidiaries has
retained or assumed, in whole or in part, contractually, by operation of law or
otherwise, which, in the aggregate, could reasonably be expected to result in a
Material Adverse Effect, nor do the Borrower or the Subsidiaries have reason to
believe that any such Environmental Claim is being threatened; and

     (e)  Neither the Borrower nor any of the Subsidiaries has generated or
transported Hazardous Materials from the Properties, in any case in a manner
that could give rise to liability under any Environmental Law, nor have the
Borrower or the Subsidiaries retained or assumed any liability, contractually,
by operation of law or otherwise, with respect to the generation or
transportation of Hazardous Materials, which generation or transportation, or
retained or assumed liabilities, in the aggregate, could reasonably be expected
to result in a Material Adverse Effect.

     SECTION 3.18.  Insurance. Schedule 3.18 sets forth a complete and correct
summary description of all insurance maintained by the Borrower or the
Subsidiaries as of the Closing Date. As of the Closing Date, such insurance is
in full force and effect and all premiums have been duly paid. The Borrower and
the Subsidiaries have insurance in such amounts and covering such risks and
liabilities as are in accordance with normal industry practice.

     SECTION 3.19.  Security Documents. (a) Subject to the provisions of Section
9.17, each Pledge Agreement is effective to create in favor of the Collateral
Agent, for the ratable benefit of the Secured Parties, a legal, valid and
enforceable security interest in the Collateral (as defined in such Pledge
Agreement), and when such Collateral is delivered to the Collateral Agent such
Pledge Agreement will constitute a fully perfected first priority Lien on and
security interest in all right, title and interest of each pledgor thereunder in
such Collateral, in each case prior and superior in right to any other person.

     (b)  Subject to the provisions of Section 9.17, each Security Agreement is
effective to create in favor of the Collateral Agent, for the ratable benefit of
the Secured Parties, a legal, valid and enforceable security interest in the

statements in appropriate form are filed in the offices specified on Schedule 6
to the Perfection Certificate, such Security Agreement will constitute a fully
perfected Lien on and security interest in all right, title and interest of the
grantors thereunder in such Collateral, in each case prior and superior in right
to any other person, other than with respect to Liens expressly permitted by
Section 6.02.

     (c)  Subject to the provisions of Section 9.17, when a Security Agreement
(or an appropriate memorandum of security agreement) is filed in the United
States Patent and Trademark Office and the United States Copyright Office, such
Security Agreement will constitute a fully perfected Lien on, and security
interest in, all right, title and interest of the grantors thereunder in the
Intellectual Property (as defined in such Security Agreement), in each case
prior and superior in right to any other person.

     (d)  Subject to the provisions of Section 9.17, the Mortgages are effective
to create in favor of the Collateral Agent, for the ratable benefit of the
Secured Parties, a legal, valid and enforceable Lien on all the Loan Parties'
right, title and interest in and to the Mortgaged Properties and the proceeds
thereof, and when the Mortgages are filed in the offices specified on Schedule
3.19(d), the Mortgages will constitute fully perfected Liens on, and security
interests in, all right, title and interest of the Loan Parties in the Mortgaged
Properties and the proceeds thereof, in each case prior and superior in right to
any other person, other than with respect to the rights of persons pursuant to
Liens expressly permitted by Section 6.02.

     (e)  On the Closing Date, after giving effect to the Closing Date
Transactions, and at all times thereafter, the Collateral and Guarantee
Requirement will have been satisfied.
<PAGE>

                                                                              49

     SECTION 3.20. Intellectual Property. The Borrower and each Subsidiary
owns, or is licensed to use, all patents, trademarks, tradenames, service marks,
copyrights, technology, know-how and processes (together with all applications
therefor and licenses granting rights therein, "Intellectual Property")
necessary for the conduct of its business as currently conducted, except for
those the failure to own or be licensed to use which could not reasonably be
expected to result in a Material Adverse Effect. The use of Intellectual
Property by the Borrower and its Subsidiaries does not infringe on the rights
of, and no Intellectual Property of the Borrower or any of its Subsidiaries is
being infringed upon by, any Person, and no claim is pending or threatened
challenging the use or the validity of any Intellectual Property of the Borrower
or any Subsidiary, except for infringements and claims that, in the aggregate,
could not reasonably be expected to result in a Material Adverse Effect.

     SECTION 3.21. Location of Real Property and Leased Premises. (a) Schedule
3.21(a) lists completely and correctly as of the Closing Date all real property
owned by the Borrower and the Subsidiaries and the addresses thereof (other than

lockouts or slowdowns against the Borrower or any of the Subsidiaries pending
or, to the knowledge of the Borrower or any of the Subsidiaries, threatened. The
hours worked by and payments made to employees of the Borrower and the
Subsidiaries have not been in violation of the Fair Labor Standards Act or any
other applicable Federal, state, local or foreign law dealing with such matters.
All payments due from the Borrower or any of the Subsidiaries, or for which any
claim may be made against the Borrower or any of the Subsidiaries, 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 the applicable
Subsidiary. The consummation of the Transactions will not give rise to any right
of termination or right of renegotiation on the part of any union under any
collective bargaining agreement to which the Borrower or any of the Subsidiaries
is bound.

     SECTION 3.23. Solvency. Immediately after the consummation of the Closing
Date Transactions, (i) the fair value of the assets of each Loan Party will
exceed its debts and liabilities, subordinated, contingent or otherwise; (ii)

will be able to pay its debts and liabilities, subordinated, contingent or
otherwise, as such debts and liabilities become absolute and matured; and (iv)

Borrower and, to the knowledge of the Borrower, the Seller, set forth in the
Purchase Agreement are true and correct as of the date hereof in all material

                                  ARTICLE IV

                                  Conditions

     material respect when so made, deemed made or furnished;

          (b) default shall be made in the payment of any principal of any Loan
     or any reimbursement with respect to any L/C Disbursement when and as the

          (c) default shall be made in the payment of any interest on any Loan

     for a period of three Business Days;

          (d) default shall be made in the due observance or performance by the

     covenant, condition or agreement contained in any agreement or instrument
     evidencing or governing any such Material Indebtedness, or any other event
     or condition shall occur, if the effect of any failure or other event or
     condition referred to in this clause (ii) is to cause, or permit (with or
     without the giving of notice, the lapse of time or both) the holder or
     holders of such Material Indebtedness or a trustee on its or their behalf
     to cause, such Material Indebtedness to become due or to be required to be
     repurchased, redeemed or defeased prior to its stated maturity, provided
     that this clause (f) shall not apply to secured Indebtedness that becomes
     due as a result of any voluntary sale or transfer of the property or assets
     securing such Indebtedness that is otherwise permitted hereunder;

          (g) an involuntary proceeding shall be commenced or an involuntary
     petition shall be filed in a court of competent jurisdiction seeking (i)
     relief in respect of the Borrower or any of the Subsidiaries, or of a
     substantial part of the property or assets of the Borrower or a Subsidiary,

     liabilities with respect to which the Borrower has a contractual right of
     reimbursement from a Governmental Authority pursuant to a Government

     first priority security interest in the securities, assets or properties
     covered thereby (except in all cases as otherwise provided in this
     Agreement, the Guarantee Agreement or any Security Document); or

          (l) there shall have occurred a Change in Control;

then, and in every such event (other than an event with respect to the Borrower
described in paragraph (g) or (h) above), and at any time thereafter during the
continuance of such event, the Administrative Agent, at the request of the
Required Lenders, shall, by notice to the Borrower, take either or both of the
following actions, at the same or different times: (i) terminate forthwith the
Commitments and (ii) declare the Loans then outstanding to be forthwith due and

presentment, demand, protest or any other notice of any kind, all of which are

                                 ARTICLE VIII

                                  The Agents

     In order to expedite the transactions contemplated by this Agreement, CSFB
  is hereby appointed to act as Administrative Agent and Collateral Agent on
  behalf of the Lenders and Issuing Banks (for purposes of this Article VIII,
  the Administrative Agent and the Collateral Agent are referred to collectively
  as the "Agents"). Each of the Lenders, each assignee of any such Lender and
  each Issuing Bank hereby irrevocably authorizes the Agents to take such
  actions on behalf of such Lender or assignee or such Issuing Bank and to
  exercise such powers as are specifically delegated to the Agents by the terms
  and provisions hereof and of the other Loan Documents, together with such
  actions and powers as are reasonably incidental thereto. The Administrative
  Agent is hereby expressly authorized by the Lenders and the Issuing Banks,
  without hereby limiting any implied authority, (a) to receive on behalf of the
  Lenders and the Issuing Banks all payments of principal of and interest on the
  Loans, all payments in respect of L/C Disbursements and all other amounts due
  to the Lenders hereunder, and promptly to distribute to each Lender or Issuing
  Bank its proper share of each payment so received; (b) to give notice on
  behalf of each of the Lenders to the Borrower of any Event of Default
  specified in this Agreement of which the Administrative Agent has actual
  knowledge acquired in connection with its agency hereunder; and (c) to
  distribute to each Lender copies of all notices, financial statements and
  other materials delivered by the Borrower or any other Loan Party pursuant to
  this Agreement or the other Loan Documents as received by the Administrative
  Agent. Without limiting the generality of the foregoing, the Agents are hereby
  expressly authorized to execute any and all documents (including releases)
  with respect to the Collateral and the Guarantee Agreements and the rights of
  the Secured Parties with respect thereto, as contemplated by and in accordance
  with the provisions of this Agreement, the Security Documents and the
  Guarantee Agreements, and the Agents are hereby expressly authorized to rely
  on any certificate delivered by the Borrowers as to adverse tax consequences,
  third party consent requirements, expenses, regulatory consequences or other
  matters relating to the Collateral and Guarantee Requirement, including any
  certificate delivered under Section 4.02(h), 5.03(d) or 9.08(b).

     Neither the Agents nor any of their respective directors, officers,
employees or agents shall be liable as such for any action taken or omitted by
any of them except for its or his own gross negligence or wilful misconduct, or
be responsible for any statement, warranty or representation herein or the
contents of any document delivered in connection herewith, or be required to
ascertain or to make any inquiry concerning the performance or observance by the
Borrower or any other Loan Party of any of the terms, conditions, covenants or
agreements contained in any Loan Document. The Agents shall not be responsible
to the Lenders for the due execution, genuineness, validity, enforceability or
effectiveness of this Agreement or any other Loan Documents, instruments or
agreements. The Agents shall in all cases be fully protected in acting, or
refraining from acting, in accordance with written instructions signed by the
Required Lenders and, except as otherwise specifically provided herein, such
instructions and any action or inaction pursuant thereto shall be binding on all
the Lenders. Each Agent shall, in the absence of knowledge to the contrary, be
entitled to rely on any instrument or document believed by it in good faith to
be genuine and correct and to have been signed or sent by the proper person or
persons. Neither the Agents nor any of their respective directors, officers,
employees or agents shall have any responsibility to the Borrower or any other
Loan

                                                                              67

Party on account of the failure of or delay in performance or breach by any
Lender or Issuing Bank of any of its obligations hereunder or to any Lender or
Issuing Bank on account of the failure of or delay in performance or breach by
any other Lender or Issuing Bank or the Borrower or any other Loan Party of any
of their respective obligations hereunder or under any other Loan Document or in
connection herewith or therewith. Each of the Agents 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 it with respect to all matters
arising hereunder and shall not be liable for any action taken or suffered in
good faith by it in accordance with the advice of such counsel.

     The Lenders hereby acknowledge that neither Agent shall be under any duty
to take any discretionary action permitted to be taken by it pursuant to the
provisions of this Agreement 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, either Agent may resign at any time by notifying the Lenders and the
Borrower. Upon any such resignation, the Required Lenders, acting jointly with
the Borrower if no Event of Default shall have occurred and be continuing, shall
have the right to appoint a successor. If no successor shall have been so
appointed and shall have accepted such appointment within 30 days after the
retiring Agent gives notice of its resignation, 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 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 9.05 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, each Agent in its
individual capacity and not as Agent shall have the same rights and powers as
any other Lender and may exercise the same as though it were not an Agent, and
the Agents and their Affiliates may accept deposits from, lend money to and
generally engage in any kind of business with the Borrower or any of the
Subsidiaries or other Affiliate thereof as if it were not an Agent.

     Each Lender acknowledges that it has, independently and without reliance
upon the Agents 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 Agents 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.

shall survive the making by the Lenders of the Loans and the issuance of Letters
of Credit by the Issuing Banks, regardless of any investigation made by the
Lenders or the Issuing Bank or on their behalf, and shall continue in full force
and effect as long as the principal of or any accrued interest on any Loan or
any Fee or any other amount payable under this Agreement or any other Loan
Document is outstanding and unpaid or any Letter of Credit is outstanding and so
long as the Commitments have not been terminated. The provisions of Sections
2.15, 2.17, 2.21, 9.05 and 9.16 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 expiration of the Commitments, the expiration of any Letter of
Credit, 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 Administrative Agent, the Collateral Agent, any Lender or any Issuing
Bank.

     SECTION 9.03. Binding Effect. This Agreement shall become effective when it
shall have been executed by the Borrower and the Administrative Agent and when
the Administrative Agent shall have received counterparts hereof which, when

and their respective permitted successors and assigns.

     SECTION 9.04. Successors and Assigns. (a) Whenever in this Agreement any of
the parties hereto is referred to, such reference shall be deemed to include the
permitted successors and assigns of such party; and all covenants, promises and
agreements by or on behalf of the Borrower, the Administrative Agent, the
Issuing Banks or the Lenders that are contained in this Agreement shall bind and
inure to the benefit of their respective successors and assigns.

     (b) Each Lender may assign to one or more assignees all or a portion of its
interests, rights and obligations under this Agreement (including all or a
portion of any or all of its Commitments and the Loans at the time owing to it);
provided, however, that (i) except in the case of an assignment to another
Lender or an Affiliate or Related Fund of the assigning Lender or another Lender
(x) the Borrower, unless an Event of Default shall have occurred and be
continuing, and the Administrative Agent (and, in the case of any assignment of
a Revolving Credit Commitment, each Issuing Bank and the Swingline Lender) must
give their prior written consent to such assignment (which consent shall not be
unreasonably withheld) and (y) the amount of the Revolving Credit Commitment and
the Term Loan Commitment or outstanding Term Loans of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and
Acceptance with respect to such assignment is delivered to the Administrative
Agent) shall not be less than $5,000,000 in the aggregate (or, if less, the
entire
<PAGE>

                                                                              69

Term Loans), (ii) each assignment of any rights and obligations in respect of
any class of Commitments or Loans shall be made as an assignment of a
proportionate part of all the assigning Lenders rights and obligations in
respect of such class and (iii) the assignee, if it shall not be a Lender, shall
deliver to the Administrative Agent an Administrative Questionnaire and any tax
form as required by the Internal Revenue Service or Section 2.21(e) of this
Agreement, if applicable. Upon acceptance and recording pursuant to paragraph
(e) of this Section 9.04 and payment, from and after the effective date
specified in each Assignment and Acceptance, which effective date shall be at
least five Business Days after the execution thereof, (A) the assignee
thereunder shall be a party hereto and, to the extent of the interest assigned
by 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 of the interest assigned by such Assignment and Acceptance, 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

hereto but shall continue to be entitled to the benefits of Sections 2.15, 2.17,
2.21 and 9.05, as well as to any Fees accrued for its account and not yet paid,

Lender thereunder and the assignee thereunder shall be deemed to confirm to and
agree with each other and the other parties hereto as follows: (i) such
assigning Lender warrants that it is the legal and beneficial owner of the

effect to assignments thereof which have not become effective, are as set forth
in such Assignment and Acceptance, (ii) except as set forth in (i) above, such
assigning Lender makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made in or in connection with this Agreement, or the execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement,
any other Loan Document or any other instrument or document furnished pursuant
hereto, or the financial condition of the Borrower or any of the Subsidiaries or
the performance or observance by the Borrower or any of the Subsidiaries of any
of its obligations under this Agreement, any other Loan Document or any other
instrument or document furnished pursuant hereto; (iii) such assignee represents
and warrants that it is legally authorized to enter into such Assignment and
Acceptance; (iv) such assignee confirms that it has received a copy of this
Agreement, together with copies of the most recent financial statements referred
to in Section 3.05(a) or delivered pursuant to Section 5.03 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; (v) such
assignee will independently and without reliance upon the Administrative Agent,
the Collateral Agent, 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; (vi) such assignee appoints and authorizes the Administrative
Agent and the Collateral Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement as are delegated to the Administrative
Agent and the Collateral Agent, respectively, by the terms hereof, together with
such powers as are reasonably incidental thereto; and (vii) 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.

Acceptance delivered to it and a register for the recordation of the names and
addresses of the Lenders, and the Commitments 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 and the Borrower,
the Administrative Agent, the Issuing Banks, the Collateral Agent and the
Lenders may treat each person whose name is recorded in the Register pursuant to
the terms hereof as a Lender

                                                                              70

hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary. The Register and any Assignments and Acceptances delivered to the
Administrative Agent pursuant to this Section 9.04(d) shall be available for
inspection by the Borrower, any Issuing Bank, the Collateral Agent 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, an Administrative Questionnaire
completed in respect of the assignee (unless the assignee shall already be a
Lender hereunder), a processing and recordation fee of $3,500 (which shall be
paid by the assigning Lender and such assignee as they may agree) and, if
required, the written consent of the Borrower, the Issuing Banks and the
Administrative Agent to such assignment, the Administrative Agent shall (i)
accept such Assignment and Acceptance, (ii) record the information contained
therein in the Register and (iii) give prompt notice thereof to the Borrower,
Lenders and the Issuing Banks. No assignment shall be effective unless it has
been recorded in the Register as provided in this paragraph (e).

     (f) Each Lender may without the consent of the Borrower, the Issuing Banks,
the Swingline Lender or the Administrative 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); 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 2.15, 2.17 and 2.21, and
shall be bound by the confidentiality provisions contained in Section 9.16, to
the same extent as is such Lender and (iv) the Borrower, the Administrative
Agent, the Issuing Banks and the 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 or L/C
Disbursements and to approve any amendment, modification or waiver of any
provision of this Agreement (other than amendments, modifications or waivers
decreasing any fees payable hereunder or the amount of principal of or the rate
at which interest is payable on the Loans, extending any scheduled principal
payment date or date fixed for the payment of interest on the Loans, increasing
or extending the Commitments or releasing Guarantors or all or any substantial
part of the Collateral, other than in connection with any sale of a Guarantor or
of Collateral permitted under the terms of this Agreement and the other Loan
Documents).

     (g) Any Lender or participant may, in connection with any assignment or
participation or proposed assignment or participation pursuant to this Section
9.04, 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 of
information designated by the Borrower as confidential, 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 such confidential information on
terms no less restrictive than those applicable to the Lenders pursuant to
Section 9.16.

     (h) Any Lender may at any time assign all or any portion of its rights
under this Agreement 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
Bank for such Lender as a party hereto. In order to facilitate such an
assignment to a Federal Reserve Bank, the Borrower shall, at the request of the
assigning Lender, duly execute and deliver to the assigning Lender a promissory
note or notes evidencing the Loans made to the Borrower by the assigning Lender
hereunder.

     (i) Notwithstanding anything to the contrary contained herein, any Lender
(a "Granting Lender") may grant to a special purpose funding vehicle (an "SPC"),
identified as such in writing from time to time by the Granting Lender to the
Administrative Agent and the Borrower,
<PAGE>

                                                                              71

the option to provide to the Borrower all or any part of any Loan that such
Granting Lender would otherwise be obligated to make to the Borrower pursuant to
this Agreement; provided that (i) nothing herein shall constitute a commitment
by any SPC to make any Loan and (ii) if an SPC elects not to exercise such
option or otherwise fails to provide all or any part of such Loan, the Granting
Lender shall be obligated to make such Loan pursuant to the terms hereof. The
making of a Loan by an SPC hereunder shall utilize the Commitment of the
Granting Lender to the same extent, and as if, such Loan were made by such
Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for
any indemnity or similar payment obligation under this Agreement (all liability
for which shall remain with the Granting Lender). In furtherance of the
foregoing, each party hereto hereby agrees (which agreement shall survive the
termination of this Agreement) that, prior to the date that is one year and one
day after the payment in full of all outstanding commercial paper or other
senior indebtedness of any SPC, it will not institute against, or join any other
person in instituting against, such SPC any bankruptcy, reorganization,
arrangement, insolvency or liquidation proceedings under the laws of the United
States or any State thereof. In addition, notwithstanding anything to the
contrary in this Section 9.04, any SPC may (i) with notice to, but without the
prior written consent of, the Borrower and the Administrative Agent and without
paying any processing fee therefor, assign all or a portion of its interests in
any Loans to the Granting Lender or to any financial institutions (consented to
by the Borrower and the Administrative Agent) providing liquidity and/or credit
support to or for the account of such SPC to support the funding or maintenance
of Loans and (ii) disclose on a confidential basis any non-public information
relating to its Loans to any rating agency, commercial paper dealer or provider
of any surety, guarantee or credit or liquidity enhancement to such SPC. This
section may not be amended without the written consent of the SPC.

     (j) The Borrower shall not assign or delegate any of its rights or duties
hereunder without the prior written consent of the Administrative Agent, each
Issuing Bank and each Lender, and any such attempted assignment without such
consent shall be null and void.

     (k) In the event that S&P, Moody's and Thompson's BankWatch (or
InsuranceWatch Ratings Service, in the case of Lenders that are insurance
companies (or Best's Insurance Reports, if such insurance company is not rated
by Insurance Watch Ratings Service)) shall, after the date that any Lender
becomes a Revolving Credit Lender, downgrade the long-term certificate deposit
ratings of such Lender, and the resulting ratings shall be below BBB-, Baa3 and
C (or BB, in the case of a Lender that is an insurance company (or B, in the
case of an insurance company not rated by InsuranceWatch Ratings Service)), then
the administrative Agent or a majority in interest (based on L/C Commitments) of
the Issuing Banks shall have the right, but not the obligation, at its own
expense, upon notice to such Lender and the Administrative Agent, to replace (or
to request the Borrower to use its reasonable efforts to replace) such Lender
with an assignee (in accordance with and subject to the restrictions contained
in paragraph (b) above), and such Lender hereby agrees to transfer and assign
without recourse (in accordance with and subject to the restrictions contained
in paragraph (b) above) all its interests, rights and obligations in respect of
its Revolving Credit Commitment to such assignee; provided, however, that (i) no
such assignment shall conflict with any law, rule and regulation or order of any
Governmental Authority and (ii) the Borrower or such assignee, as the case may
be, shall pay to such Lender in immediately available funds on the date of such
assignment the principal of and interest accrued to the date of payment on the
Loans made by such Lender hereunder and all other amounts accrued for such
Lender's account or owed to it hereunder.

     SECTION 9.05. Expenses; Indemnity. (a) The Borrower agrees to pay upon
request all out-of-pocket expenses incurred by the Arranger, the Administrative
Agent, the Collateral Agent, each Issuing Bank and the Swingline Lender and
their respective Affiliates in connection with the syndication of the credit
facilities provided for herein and the preparation and administration of this
Agreement and the other Loan Documents or in connection with any amendments,
modifications or waivers of the provisions hereof or thereof (whether or not the
transactions hereby or thereby contemplated shall be consummated) or incurred by
the Administrative Agent, the Collateral Agent, any Issuing Bank, the Swingline
Lender or any Lender in connection with the enforcement (including in connection
with the negotiation of any
<PAGE>

                                                                              72

restructuring or "work out" (whether or not consummated) of the Obligations) or
protection of its rights in connection with this Agreement and the other Loan
Documents or in connection with the Loans made or Letters of Credit issued
hereunder, including the fees, charges and disbursements of Cravath, Swaine &
Moore, counsel for the Arranger, the Administrative Agent and the Collateral
Agent, local counsel retained by the Collateral Agent in connection with the
satisfaction of the Collateral and Guarantee Requirement and, in connection with
any such enforcement or protection, the fees, charges and disbursements of any
other counsel for the Administrative Agent, the Collateral Agent, any Issuing
Bank, the Swingline Lender or any Lender.

     (b) The Borrower agrees to indemnify the Administrative Agent, the
Collateral Agent, each Lender, each Issuing Bank and the Swingline Lender, each
Affiliate of any of the foregoing persons and each of their respective
directors, officers, employees, agents and controlling persons (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, charges and disbursements, 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 and the other transactions contemplated
thereby, (ii) the use of the proceeds of the Loans or issuance of Letters of
Credit, (iii) any claim, litigation, investigation or proceeding relating to any
of the foregoing, whether or not any Indemnitee is a party thereto, or (iv) any
actual or alleged presence or Release of Hazardous Materials on any property
owned, leased or operated by the Borrower or any of the Subsidiaries, or any
Environmental Claim related in any way to the Borrower or the Subsidiaries;
provided that such indemnity shall not, as to any Indemnitee, be available to
the extent that such losses, claims, damages, liabilities or related expenses
are determined by a court of competent jurisdiction by final and nonappealable
judgment to have resulted from the gross negligence or wilful misconduct of such
Indemnitee.

     (c) To the extent that the Borrower fails to pay any amount required to be
paid by it to the Administrative Agent, the Collateral Agent, any Issuing Bank
or the Swingline Lender under paragraph (a) or (b) of this Section, each Lender
severally agrees to pay to the Administrative Agent, the Collateral Agent, such
Issuing Bank or the Swingline Lender, as the case may be, such Lender's pro rata
share (determined as of the time that the applicable unreimbursed expense or
indemnity payment is sought) of such unpaid amount; provided that the
unreimbursed expense or indemnified loss, claim, damage, liability or related
expense, as the case may be, was incurred by or asserted against the
Administrative Agent, the Collateral Agent, such Issuing Bank or the Swingline
Lender in its capacity as such. For purposes hereof, a Lender's "pro rata share"
shall be determined based upon its share of the sum of the total Revolving
Credit Exposures, outstanding Term Loans and unused Commitments at the time.

     (d) To the extent permitted by applicable law, the Borrower shall not
assert, and hereby waives, any claim against any Indemnitee, on any theory of
liability, for special, indirect, consequential or punitive damages (as opposed
to direct or actual damages) arising out of, in connection with, or as a result
of, this Agreement or any agreement or instrument contemplated hereby, the
Transactions, any Loan or Letter of Credit or the use of the proceeds thereof.

     (e) The provisions of this Section 9.05 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 expiration of the Commitments, the expiration of any Letter of
Credit, 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 Administrative Agent, the Collateral Agent, any Lender or any Issuing
Bank. All amounts due under this Section 9.05 shall be payable on written demand
therefor.

     SECTION 9.06. Right of Setoff. If an Event of Default shall have occurred
and be continuing, each Lender and Issuing Bank is hereby authorized at any time
and from time to
<PAGE>

                                                                              73

time, except to the extent prohibited 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 or Issuing Bank, as
the case may be, 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 or Issuing Bank 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 and Issuing Bank under this Section 9.06
are in addition to other rights and remedies (including other rights of setoff)
which such Lender or Issuing Bank may have.

          SECTION 9.07. Applicable Law. THIS AGREEMENT AND THE OTHER LOAN
DOCUMENTS (OTHER THAN LETTERS OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN
DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE
STATE OF NEW YORK. EACH LETTER OF CREDIT SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED IN ACCORDANCE WITH, THE LAWS OR RULES DESIGNATED IN SUCH LETTER OF
CREDIT, OR IF NO SUCH LAWS OR RULES ARE DESIGNATED, THE UNIFORM CUSTOMS AND
PRACTICE FOR DOCUMENTARY CREDITS (1993 REVISION), INTERNATIONAL CHAMBER OF
COMMERCE, PUBLICATION NO. 500 (THE "UNIFORM CUSTOMS") AND, AS TO MATTERS NOT
GOVERNED BY THE UNIFORM CUSTOMS, THE LAWS OF THE STATE OF NEW YORK.

          SECTION 9.08. Waivers; Amendment. (a) No failure or delay of the
Borrower, the Administrative Agent, the Collateral Agent, any Lender or any
Issuing Bank in exercising any power or right hereunder or under any other Loan
Document shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right or power, or any 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 Borrower, the Administrative Agent, the Collateral Agent, the Issuing Banks
and the Lenders hereunder and under the other Loan Documents are cumulative and
are not exclusive of any rights or remedies that 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 or any other Loan Party 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.

          (b) None of this Agreement or any other Loan Document or any provision
hereof or thereof may be waived, amended or modified except pursuant to an
agreement or agreements in writing entered into by the Borrower and the Required
Lenders (and, in the case of any other Loan Document, any other person whose
consent is required thereunder); provided, however, that no such agreement shall
(i) decrease the principal amount of, or extend the maturity of or any scheduled
principal payment date or date for the payment of any interest on, any Loan or
any fees or any date for reimbursement of an L/C Disbursement, or waive or
excuse any such payment or any part thereof, or amend or modify the provisions
of Section 2.10(c) or 2.14(a), or amend or modify the definition of the term
"Revolving Credit Maturity Date", or decrease the rate of interest on any Loan
or L/C Disbursement or the amount of any fees, without the prior written consent
of each Lender affected thereby, (ii) change or extend any Commitment (including
pursuant to Section 2.24) or decrease or extend the date for payment of the
Commitment Fees of any Lender without the prior written consent of such Lender,
(iii) amend or modify the provisions of Section 2.18, 2.19 or 9.04(j), the
provisions of this Section or the definition of the term "Required Lenders" or
release any Guarantors or all or any substantial part of the Collateral (other
than as contemplated under section 9.17) without the prior written consent of
each Lender, (iv) except as provided in Section 2.14(j), waive or change the
allocation between Tranche A Term Loans and Tranche B Term Loans of any
prepayment pursuant to Section 2.13 or 2.14 without the prior written consent of
Lenders holding more than 50% of the aggregate outstanding principal amount of
the Tranche A Term Loans and more than 50% of the aggregate outstanding
principal amount of the Tranche B Term Loans or (v) amend
<PAGE>

                                                                              74

Section 2.14(j) without the prior written consent of the Lenders holding a
majority of the aggregate outstanding principal amount of the Tranche B Term
Loans; provided further that (i) no such agreement that by its terms adversely
affects the rights of the Revolving Credit Lenders, the Tranche A Lenders or the
Tranche B Lenders in a manner different from its effect on the other classes of
Lenders shall become effective unless approved by a majority in interest of each
class of lenders so adversely affected and (ii) no such agreement shall amend,
modify or otherwise affect the rights or duties of the Administrative Agent, the
Collateral Agent, any Issuing Bank or the Swingline Lender hereunder or under
any other Loan Document without the prior written consent of the Administrative
Agent, the Collateral Agent, such Issuing Bank or the Swingline Lender.

          SECTION 9.09. Interest Rate Limitation. Notwithstanding anything
herein to the contrary, if at any time the interest rate applicable to any Loan
or participation in any L/C Disbursement, together with all fees, charges and
other amounts which are treated as interest on such Loan or participation in
such L/C Disbursement under applicable law (collectively the "Charges"), shall
exceed the maximum lawful rate (the "Maximum Rate") which may be contracted for,
charged, taken, received or reserved by the Lender holding such Loan or
participation in accordance with applicable law, the rate of interest payable in
respect of such Loan or participation hereunder, together with all Charges
payable in respect thereof, shall be limited to the Maximum Rate and, to the
extent lawful, the interest and Charges that would have been payable in respect
of such Loan or participation but were not payable as a result of the operation
of this Section 9.09 shall be cumulated and the interest and Charges payable to
such Lender in respect of other Loans or participations or periods shall be
increased (but not above the Maximum Rate therefor) until such cumulated amount,
together with interest thereon at the Federal Funds Effective Rate to the date
of repayment, shall have been received by such Lender.

          SECTION 9.10. Entire Agreement. This Agreement and the other Loan
Documents constitute the entire contract between the parties relative to the
subject matter hereof. Any other 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 9.11. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT
OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN
DOCUMENTS. EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR
ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH
OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING
WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN
INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS, AS
APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN
THIS SECTION 9.11.

          SECTION 9.12. 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 (it being understood that
the invalidity of a particular provision in a particular jurisdiction shall not
in and of itself affect the validity of such provision in any other
jurisdiction). 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 9.13. Counterparts. This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together shall
constitute a single contract, and shall become effective as provided in Section
9.03. Delivery of an executed signature page to this Agreement by facsimile
transmission shall be as effective as delivery of a manually signed counterpart
of this Agreement.

          SECTION 9.14. 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 9.15. 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
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
Administrative Agent, the Collateral Agent, any Issuing Bank or any Lender may
otherwise have to bring any action or proceeding relating to this Agreement or
the other Loan Documents against the Borrower or its properties 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 9.01. 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 9.16. Confidentiality. (a) The Administrative Agent, the
Collateral Agent, each Issuing Bank and each of the Lenders agrees to keep
confidential (and to use its best efforts to cause its respective agents and
representatives to keep confidential) the Information (as defined below) and all
copies thereof, extracts therefrom and analyses or other materials based
thereon, except that the Administrative Agent, the Collateral Agent, any Issuing
Bank or any Lender shall be permitted to disclose Information (a) to such of its
respective officers, directors, employees, agents, affiliates and
representatives as need to know such Information in connection with the
performance of their duties related to the Loan Documents and the transactions
contemplated thereby or the legal and regulatory compliance requirements of the
Administrative Agent, the Collateral Agent, such Issuing Bank or such Lender, as
the case may be, (b) to the extent requested by any regulatory authority,
including the National Association of Insurance Commissioners or any successor
entity thereto, (c) to the extent otherwise required by applicable laws and
regulations or by any subpoena or similar legal process, (d) in connection with
any suit, action or proceeding relating to the enforcement of its rights
hereunder or under the other Loan Documents, (e) to any direct or indirect
contractual counterparty in swap agreements or such contractual counterparty's
professional advisor (so long as such contractual counterparty or professional
advisor to such contractual counterparty agrees to be bound by the provisions of
this Section 9.16) or (f) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section 9.16 or (ii)
becomes available to the Administrative Agent, any Issuing Bank, any Lender or
the Collateral Agent on a nonconfidential basis from a source other than the
Borrower or any Affiliate of the Borrower;
<PAGE>

                                                                              76

provided, however, that the Administrative Agent, the Collateral Agent, any
Issuing Bank and/or any Lender, as the case may be, shall (to the extent it may
lawfully do so) provide the Borrower, to the extent practicable, with advance
notice of any disclosure of information referred to in clauses (c) and (d)
above. For the purposes of this Section, "Information" shall mean all financial
statements, certificates, reports, agreements and information (including all
analyses, compilations and studies prepared by the Administrative Agent, the
Collateral Agent, any Issuing Bank or any Lender based on any of the foregoing
and including any budget, programming and program scheduling information) that
are received from the Borrower or any Subsidiary and related to, the Borrower or
any Subsidiary, other than any of the foregoing that were available to the
Administrative Agent, the Collateral Agent, any Issuing Bank or any Lender on a
nonconfidential basis prior to its disclosure thereto by the Borrower or any
Subsidiary. The provisions of this Section 9.16 shall remain operative and in
full force and effect regardless of the expiration and term of this Agreement.

          (b) The Administrative Agent and the Lenders acknowledge that the
Borrower and its Subsidiaries perform classified contracts funded by and/or for
the benefit of the United States Federal government and, accordingly, neither
the Borrower nor any Subsidiary will be obligated to release, disclose or
otherwise make available to the Administrative Agent or any Lender any
classified or special nuclear material to any parties not in possession of a
valid security clearance and authorized by the appropriate agency of the United
States Federal government to receive such material. The Administrative Agent and
the Lenders agree that in connection with any exercise of a right or remedy the
United States Federal government may remove classified information or
government-issued property prior to any remedial action implicating such
classified information or government-issued property. Upon notice from the
Borrower, the Administrative Agent and the Lenders shall take such steps in
accordance with this Agreement as may be reasonably requested by the Borrower to
enable the Borrower or any Subsidiary to comply with the Foreign Ownership
Control or Influence requirements of the United States Federal government
imposed from time to time.

          SECTION 9.17. Releases of Guarantors and Collateral. (a)
Notwithstanding any contrary provision herein or in any other Loan Document, if
the Borrower shall request the release under the Guarantee Agreement or any
Security Document of any Guarantor or any Collateral permitted to be sold under
the terms of the Loan Documents and shall deliver to the Collateral Agent a
certificate to the effect that such Sale and the disposition of the proceeds
thereof will comply with the terms of this Agreement, the Collateral Agent, if
satisfied that the applicable certificate is correct, shall, without the consent
of any Lender, execute and deliver all such instruments, releases, financing
statements or other agreements, and take all such further actions, as shall be
necessary to effectuate the release of such Guarantor or such Collateral.

          (b) Notwithstanding Section 5.09, Section 6.11 or any other provision
herein or in any other Loan Document, the Collateral Agent is hereby authorized
and directed to release (i) the Collateral (other than Collateral consisting of
Equity Interests in, or Indebtedness of, Subsidiaries, or the proceeds thereof)
and/or (ii) Collateral consisting of Equity Interests in, or Indebtedness of
Subsidiaries, or the proceeds thereof from the Liens created by the Security
Documents on one or more Business Days specified by the Borrower (each a
"Release Date"), upon the satisfaction of the following conditions precedent
(the " Release Conditions"), and subject to the reinstatement of such Liens as
provided in paragraph (c) below:

                    (A) the Borrower shall have given notice to the Collateral
          Agent at least 30 days prior to the Release Date, specifying the
          proposed Release Date;

                    (B) in the case of Collateral described in clause (b)(i)
          above, either (x) as of the Release Date, the Ratings shall be BBB- or
          better by S&P and Baa3 or better by Moody's or (y) the Consolidated
          Leverage Ratio as of the most recent fiscal quarter for which
          financial statements have been delivered under Section 5.03 (a) or (b)

                    (C) in the case of Collateral described in clause (ii)
          above, as of the Release Date, the Ratings shall be BBB- or better by
          S&P and Baa3 or better by Moody's;

                    (D) no Default or Event of Default hereunder shall have

                    (E) on the Release Date, the Administrative Agent shall have
          received a certificate, dated the Release Date and executed on behalf
          of the Borrower by a Responsible Officer thereof, confirming the
          satisfaction of the Release Conditions set forth in clauses (B) or
          (C), as applicable, and (D) above;

Any such release shall be without recourse to, or representation or warranty by,
the Collateral Agent and shall not require the consent of any Lender. Subject to
the satisfaction of the conditions set forth in this paragraph (b), on and after
the Release Date, the Collateral Agent shall, execute and deliver all such
instruments, releases, financing statements or other agreements, and take all
such further actions, as shall be necessary to effectuate the release of

Baa3 by Moody's for any period of 90 consecutive days, the requirements of
Sections 5.09 and 6.11 shall again become applicable and the Borrower shall
promptly take and cause the Subsidiaries to take all such actions as shall be
necessary or as the Collateral Agent shall reasonably request to cause the
Collateral and Guarantee Requirement to be satisfied.

          (d) Without limiting the provisions of Section 9.05, the Borrowers
shall reimburse the Collateral Agent, the Administrative Agent and the Lenders
for all costs and expenses, including attorney's fees and disbursements,
incurred by any of them in connection with any action contemplated by this
Section 9.17.

Ladies and Gentlemen:

     Morrison Knudsen Corporation, a Delaware corporation (the "Issuer"),
proposes to issue and sell to Credit Suisse First Boston Corporation, BMO
Nesbitt Burns Corp. and U.S. Bancorp Libra, a division of U.S. Bancorp
Investments, Inc. (collectively, the "Initial Purchasers"), upon the terms set
forth in a purchase agreement of even date herewith (the "Purchase Agreement"),
$300,000,000 aggregate principal amount of its 11% Senior Notes Due July 1, 2010
(the "Notes") to be unconditionally guaranteed on a senior unsecured basis (the
"Guaranties") by each of the Issuer's subsidiaries listed on Schedule A hereto
of the Purchase Agreement (the "Guarantors" and, collectively with the Issuer,
the "Company"). The Notes will also be guaranteed on a senior unsecured basis by
each existing and subsequently organized domestic subsidiary of the Issuer that
becomes a guarantor pursuant to the Indenture (as defined). The Notes and the
Guaranties are together referred to as the "Initial Securities". The Initial
Securities will be issued pursuant to an indenture, dated as of July 1, 2000
(the "Indenture"), among the Issuer, the Guarantors and United States Trust
Company of New York, as trustee (the "Trustee"). As an inducement to the Initial
Purchasers to enter into the Purchase Agreement, the Company agrees with the
Initial Purchasers, for the benefit of the Initial Purchasers and the holders
of the Securities (as defined below) (collectively the "Holders"), as follows:

     1.   Registered Exchange Offer. Unless not permitted by applicable law
(after the Company has complied with the ultimate paragraph of this Section 1),
the Company shall prepare and, not later than 75 days (such 75th day being a
"Filing Deadline") after the date on which the Initial Purchasers purchase
the Initial Securities pursuant to the Purchase Agreement (the "Closing Date"),
file with the Securities and Exchange Commission (the "Commission") a
registration statement (the "Exchange Offer Registration Statement") on an
appropriate form under the Securities Act of 1933, as amended (the "Securities
Act"), with respect to a proposed offer (the "Registered Exchange Offer") to the
Holders of Transfer Restricted Securities (as defined in Section 6 hereof), who
are not prohibited by any law or policy of the Commission from participating in
the Registered Exchange Offer, to issue and deliver to such Holders, in exchange
for the Initial Securities, a like aggregate principal amount of debt
securities of the Company issued under the Indenture, identical in all material
respects to the Initial Securities and registered under the Securities Act (the
"Exchange Securities"). The Company shall use its best efforts to (i) cause such
Exchange Offer Registration Statement to become effective under the Securities
Act within 150 days after the Closing Date (such 150th day being an
"Effectiveness Deadline") and (ii) keep the Exchange Offer Registration
Statement effective for not less than 20 Business Days (or longer, if required
by applicable law) after the date notice of the Registered Exchange Offer is
mailed to the Holders (such period being called the "Exchange Offer
Registration Period"). "Business Days" means any day that is not a Saturday, a
Sunday or a day on which banking institutions are not required to be open in
the State of New York.

     If the Company commences the Registered Exchange Offer, the Company (i)
will be entitled to consummate the Registered Exchange Offer 20 Business Days
after such commencement (provided that the Company has accepted all the Initial
Securities theretofore validly tendered in accordance with the
<PAGE>

terms of the Registered Exchange Offer) and (ii) will be required to consummate
the Registered Exchange Offer no later than 40 days after the date on which the
Exchange Offer Registration Statement is declared effective (such 40th day being
the "Consummation Deadline").

     Following the declaration of the effectiveness of the Exchange Offer
Registration Statement, the Company shall promptly commence the Registered
Exchange Offer, it being the objective of such Registered Exchange Offer to
enable each Holder of Transfer Restricted Securities electing to exchange the
Initial Securities for Exchange Securities (assuming that such Holder is not an
affiliate of the Company within the meaning of the Securities Act, acquires the
Exchange Securities in the ordinary course of such Holder's business and has no
arrangements with any person to participate in the distribution of the Exchange
Securities and is not prohibited by any law or policy of the Commission from
participating in the Registered Exchange Offer) to trade such Exchange
Securities from and after their receipt without any limitations or restrictions
under the Securities Act and without material restrictions under the securities
laws of the several states of the United States.

     The Company acknowledges that, pursuant to current interpretations by the
Commission's staff of Section 5 of the Securities Act, in the absence of an
applicable exemption therefrom, (i) each Holder which is a broker-dealer
electing to exchange Initial Securities, acquired for its own account as a
result of market making activities or other trading activities, for Exchange
Securities (an "Exchanging Dealer"), is required to deliver a prospectus
containing the information set forth in (a) Annex A hereto on the cover, (b)
Annex B hereto in the "Exchange Offer Procedures" section and the "Purpose of
the Exchange Offer" section, and (c) Annex C hereto in the "Plan of
Distribution" section of such prospectus in connection with a sale of any such
Exchange Securities received by such Exchanging Dealer pursuant to the
Registered Exchange Offer and (ii) an Initial Purchaser that elects to sell
Securities (as defined below) acquired in exchange for Initial Securities
constituting any portion of an unsold allotment, is required to deliver a
prospectus containing the information required by Items 507 or 508 of
Regulation S-K under the Securities Act, as applicable, in connection with such
sale.

     The Company shall use its best efforts to keep the Exchange Offer
Registration Statement effective and to amend and supplement the prospectus
contained therein, in order to permit such prospectus to be lawfully delivered
by all persons subject to the prospectus delivery requirements of the
Securities Act for such period of time as such persons must comply with such
requirements in order to resell the Exchange Securities; provided, however, that
                                                         --------  -------
(i) in the case where such prospectus and any amendment or supplement thereto
must be delivered by an Exchanging Dealer or an Initial Purchaser, such period
shall be the lesser of 180 days after the consummation of the Registered
Exchange Offer and the date on which all Exchanging Dealers and the Initial
Purchasers have sold all Exchange Securities held by them (unless such period is
extended pursuant to Section 3(j) below) and (ii) the Company shall make such
prospectus and any amendment or supplement thereto available to any broker-
dealer for use in connection with any resale of any Exchange Securities for a
period of not less than 180 days after the consummation of the Registered
Exchange Offer.

     If, upon consummation of the Registered Exchange Offer, any Initial
Purchaser holds Initial Securities acquired by it as part of its initial
distribution, the Company, simultaneously with the delivery of the Exchange
Securities pursuant to the Registered Exchange Offer, shall issue and deliver to
such Initial Purchaser upon the written request of such Initial Purchaser, in
exchange (the "Private Exchange") for the Initial Securities held by such
Initial Purchaser, a like principal amount of debt securities issued by the
Company under the Indenture and guaranteed by the Guarantors and identical in
all material respects to the Initial Securities (the "Private Exchange
Securities"). The Initial Securities, the Exchange Securities and the Private
Exchange Securities are herein collectively called the "Securities".

     In connection with the Registered Exchange Offer, the Company shall:

          (a)  mail to each Holder a copy of the prospectus forming part of the
     Exchange Offer Registration Statement, together with an appropriate
letter of transmittal and related documents;

          (b)  keep the Registered Exchange Offer open for not less than 20
     Business Days (or longer, if required by applicable law) after the date
     notice thereof is mailed to the Holders;

          (c)  utilize the services of a depositary for the Registered Exchange
     Offer with an address in the Borough of Manhattan, The City of New York,
     which may be the Trustee or an affiliate of the Trustee;

                                       2
<PAGE>

          (d)  permit Holders to withdraw tendered Securities at any time prior
     to the close of business, New York time, on the last business day on which
     the Registered Exchange Offer shall remain open; and

          (e)  otherwise comply with all applicable laws.

     As soon as practicable after the close of the Registered Exchange Offer or
the Private Exchange, as the case may be, the Company shall:

          (x)  accept for exchange all the Initial Securities validly tendered
     and not withdrawn pursuant to the Registered Exchange Offer and the Private
     Exchange;

          (y)  deliver to the Trustee for cancellation all the Initial
     Securities so accepted for exchange; and

          (z)  cause the Trustee to authenticate and deliver promptly to each
     Holder of the Initial Securities, Exchange Securities or Private Exchange
     Securities, as the case may be, equal in principal amount to the Initial
     Securities of such Holder so accepted for exchange.

     The Indenture will provide that the Exchange Securities will not be subject
to the transfer restrictions set forth in the Indenture and that all the
Securities will vote and consent together on all matters as one class and that
none of the Securities will have the right to vote or consent as a class
separate from one another on any matter.

     Interest on each Exchange Security and Private Exchange Security issued
pursuant to the Registered Exchange Offer and in the Private Exchange will
accrue from the last interest payment date on which interest was paid on the
Initial Securities surrendered in exchange therefor or, if no interest has been
paid on the Initial Securities, from the date of original issue of the
Initial Securities.

     Each Holder participating in the Registered Exchange Offer shall be
required to represent to the Company that at the time of the consummation of
the Registered Exchange Offer (i) any Exchange Securities received by such
Holder will be acquired in the ordinary course of business, (ii) such Holder
will have no arrangements or understanding with any person to participate in
the distribution of the Securities within the meaning of the Securities Act,
(iii) such Holder is not an "affiliate," as defined in Rule 405 of the
Securities Act, of the Company or if it is an affiliate, such Holder will
comply with the registration and prospectus delivery requirements of the
Securities Act to the extent applicable, (iv) if such Holder is not a broker-
dealer, that it is not engaged in, and does not intend to engage in, the
distribution of the Exchange Securities and (v) if such Holder is a broker-
dealer, that it will receive Exchange Securities for its own account in
exchange for Initial Securities that were acquired as a result of market-making
activities or other trading activities and that it will be required to
acknowledge that it will deliver a prospectus in connection with any resale
of such Exchange Securities.

     Notwithstanding any other provisions hereof, the Company will ensure that
(i) any Exchange Offer Registration Statement and any amendment thereto and
any prospectus forming part thereof and any supplement thereto complies in all
material respects with the Securities Act and the rules and regulations
thereunder, (ii) any Exchange Offer Registration Statement and any amendment
thereto does not, when it becomes effective, contain an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and (iii) any prospectus
forming part of any Exchange Offer Registration Statement, and any supplement to
such prospectus, does not include an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

     If following the date hereof there has been announced a change in
Commission policy with respect to exchange offers that in the reasonable opinion
of counsel to the Company raises a substantial question as to whether the
Registered Exchange Offer is permitted by applicable federal law, the Company
will seek a no-action letter or other favorable decision from the Commission
allowing the Company to consummate the Registered Exchange Offer.  The Company
will pursue the issuance of such a decision to the Commission staff level.  In
connection with the foregoing, the Company will take all such other actions as
may be requested by the Commission or otherwise required in connection with the
issuance of such decision, including without limitation (i) participating in
telephonic conferences with the Commission, (ii) delivering to the Commission
staff an analysis prepared by counsel to the Company setting forth the legal
bases, if any, upon which such counsel has concluded that the Registered
Exchange

                                       3
<PAGE>

Offer should be permitted and (iii) diligently pursuing a resolution (which need
not be favorable) by the Commission staff.

     2.  Shelf Registration.  If, (i) because of any change in law or in
applicable interpretations thereof by the staff of the Commission, the Company
is not permitted to effect a Registered Exchange Offer, as contemplated by
Section 1 hereof, (ii) the Registered Exchange Offer is not consummated by the
150th day after the Closing Date, (iii) any Initial Purchaser so requests with
respect to the Initial Securities (or the Private Exchange Securities) not
eligible to be exchanged for Exchange Securities in the Registered Exchange
Offer and held by it following consummation of the Registered Exchange Offer or
(iv) any Holder (other than an Exchanging Dealer) is not eligible to participate
in the Registered Exchange Offer or, in the case of any Holder (other than an
Exchanging Dealer) that participates in the Registered Exchange Offer, such
Holder does not receive freely tradeable Exchange Securities on the date of the
exchange and any such Holder so requests, the Company shall take the following
actions (the date on which any of the conditions described in the foregoing
clauses (i) through (iv) occur, including in the case of clauses (iii) or (iv)
the receipt of the required notice, being a "Trigger Date"):

          (a)  The Company shall promptly  (but in no event more than 45 days
     after the Trigger Date (such 45th day being a "Filing Deadline")) file with
     the Commission and thereafter use its best efforts to cause to be declared
     effective no later than 140 days after the Trigger Date (such 140th day
     being an "Effectiveness Deadline") a registration statement (the "Shelf
     Registration Statement" and, together with the Exchange Offer Registration
     Statement, a "Registration Statement") on an appropriate form under the
     Securities Act relating to the offer and sale of the Transfer Restricted
     Securities by the Holders thereof from time to time in accordance with the
     methods of distribution set forth in the Shelf Registration Statement and
     Rule 415 under the Securities Act (hereinafter, the "Shelf Registration");
     provided, however, that no Holder (other than an Initial Purchaser) shall
     --------  -------
     be entitled to have the Securities held by it covered by such Shelf
     Registration Statement unless such Holder agrees in writing to be bound by
     all the provisions of this Agreement applicable to such Holder.

          (b)  The Company shall use its best efforts to keep the Shelf
     Registration Statement continuously effective in order to permit the
     prospectus included therein to be lawfully delivered by the Holders of the
     relevant Securities, for a period of two years (or for such longer period
     if extended pursuant to Section 3(j) below) from the date of its
     effectiveness or such shorter period that will terminate when all the
     Securities covered by the Shelf Registration Statement (i) ha ve been sold
     pursuant thereto or (ii) are no longer restricted securities (as defined in
     Rule 144 under the Securities Act, or any successor rule thereof). The
     Company shall be deemed not to have used its best efforts to keep the Shelf
     Registration Statement effective during the requisite period if it
     voluntarily takes any action that would result in Holders of Securities
     covered thereby not being able to offer and sell such Securities during
     that period, unless such action is require d by applicable law.

          (c)  Notwithstanding any other provisions of this Agreement to the
     contrary, the Company shall cause the Shelf Registration Statement and the
     related prospectus and any amendment or supplement thereto, as of the
     effective date of the Shelf Registration Statement, amendment or
     supplement, (i) to comply in all material respects with the applicable
     requirements of the Securities Act and the rules and regulations of the
     Commission and (ii) not to contain any untrue statement of a material fact
     or omit to state a material fact required to be stated therein or
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading.

     in each such document, when so filed with the Commission, such comments as
     such Initial Purchaser reasonably may propose; (ii) include the information
     set forth in Annex A here to on the cover, in Annex B hereto in the

     of any broker-dealer that is the beneficial owner (as defined in Rule 13d-3
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act
     ")) of Exchange Securities received by such broker-dealer in the Registered
     Exchange Offer (a "Participating Broker-dealer"), whether such positions or
     policies have been publicly disseminated by the staff of the Commission or
     such positions or policies, in the reasonable judgment of the Initial
     Purchasers based upon advice of counsel (which may be in-house counsel),
     represent the prevailing views of the staff of the Commission; and (v) in
     the case of a Shelf Registration Statement, include the names of the
     Holders who propose to sell Securities pursuant to the Shelf Registration

     the Holders of the Securities and any Participating Broker-Dealer from whom
     the Company has received prior written notice that it will be a
     Participating Broker-Dealer in the Registered Exchange Offer (which notice
     pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction
     to suspend the use of the prospectus until the requisite changes have been
     made):

                 (i)   when the Registration Statement or any amendment thereto

          or any post-effective amendment thereto has become effective;

                 (ii)  of any request by the Commission for amendments or

                 (iii) of the issuance by the Commission of any stop order
          suspending the effectiveness of the Registration Statement or the
          initiation of any proceedings for that purpose;

                 (iv) of the receipt by the Company or its legal counsel of any
          notification with respect to the suspension of the qualification of
          the Securities for sale in any jurisdiction or the initiation or
          threatening of any proceeding for such purpose; and

                 (v)  of the happening of any event that requires the Company to
          make changes in the Registration Statement or the prospectus in order
          that the Registration Statement or the prospectus does not contain an
          untrue statement of a material fact nor omit to state a material fact
          required to be stated therein or necessary to make the statements
          therein (in the case of the prospectus, in the light of the
          circumstances under which they were made) not misleading.

          (c)  The Company shall make every reasonable effort to obtain the
     withdrawal at the earliest possible time, of any order suspending the
     effectiveness of the Registration Statement.

          (d)  The Issuer shall furnish to each Holder of Securities included
     within the coverage of the Shelf Registration, without charge, at least
     one copy of the Shelf Registration Statement and any post-effective
     amendment thereto, including financial statements and schedules, and, if
     the Holder so requests in writing, all exhibits thereto (including those,
     if any, incorporated by reference).

          (e)  The Issuer shall deliver to each Exchanging Dealer and each
     Initial Purchaser, and to any other Holder who so requests, without charge,
     at least one copy of the Exchange Offer Registration Statement and any
     post-effective amendment thereto, including financial statements and
     schedules, and, if any Initial Purchaser or any such Holder requests, all
     exhibits thereto (including those incorporated by reference).

          (f)  The Issuer shall, during the Shelf Registration Period, deliver
     to each Holder of Securities included within the coverage of the Shelf
     Registration, without charge, as many copies of the prospectus (including
     each preliminary prospectus) included in the Shelf

                                       5
<PAGE>

     Registration Statement and any amendment or supplement thereto as such
     person may reasonably request. The Company consents, subject to the
     provisions of this Agreement, to the use of the prospectus or any amendment
     or supplement thereto by each of the selling Holders of the Securities in
     connection with the offering and sale of the Securities covered by the
     prospectus, or any amendment or supplement thereto, included in the Shelf
     Registration Statement.

          (g)  The Issuer shall deliver to each Initial Purchaser, any
     Exchanging Dealer, any Participating Broker-Dealer and such other persons
     required to deliver a prospect us following the Registered Exchange Offer,
     without charge, as many copies of the final prospectus included in the
     Exchange Offer Registration Statement and any amendment or supplement
     thereto as such persons may reasonably request. The Company consents,
     subject to the provisions of this Agreement, to the use of the prospectus
     or any amendment or supplement thereto by any Initial Purchaser, if
     necessary, any Participating Broker-Dealer and such other persons required
     to deliver a prospectus following the Registered Exchange Offer in
     connection with the offering and sale of the Exchange Securities covered by
     the prospectus, or any amendment or supplement thereto, included in such
     Exchange Offer Registration Statement.

          (h)  Prior to any public offering of the Securities pursuant to any
     Registration Statement, the Company shall register or qualify or cooperate
     with the Holders of the Securities included therein and their respective
     counsel in connection with the registration or qualification of the
     Securities for offer and sale under the securities or "blue sky" laws of
     such states of the United States as any Holder of the Securities reasonably
     requests in writing and do any and all other acts or things necessary or
     advisable to enable the offer and sale in such jurisdictions of the
     Securities covered by such Registration Statement; provided, however, that
                                                        --------  -------
     the Company shall not be required to (i) qualify generally to do business
     in any jurisdiction where it is not then so qualified or (ii) take any
     action which would subject it to general service of process or to taxation
     in any jurisdiction where it is not then so subject.

          (i)  The Company shall cooperate with the Holders of the Securities to
     facilitate the timely preparation and delivery of certificates representing
     the Securities to be sold pursuant to any Registration Statement free of
     any restrictive legends and in such denominations and registered in such
     names as the Holders may request a reasonable period of time prior to
     sales of the Securities pursuant to such Registration Statement.

          (j)  Upon the occurrence of any event contemplated by paragraphs (ii)
     through (v) of Section 3(b) above during the period for which the Company
     is required to maintain an effective Registration Statement, the Company
     shall promptly prepare and file a post-effective amendment to the
     Registration Statement or a supplement to the related prospectus and any
     other required document so that, as thereafter delivered to Holders of the
     Securities or purchasers of Securities, the prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact
     required to be stated therein or necessary to make the statements therein,
     in the light of the circumstances under which they were made, not
     misleading. If the Company notifies the Initial Purchasers, the Holders of
     the Securities and any known Participating Broker-Dealer in accordance with
     paragraphs (ii) through (v) of Section 3(b) above to suspend the use of the
     prospectus until the requisite changes to the prospectus have been made,
     then the Initial Purchasers, the Holders of the Securities and any such
     Participating Broker-Dealers shall suspend use of such prospectus, and the
     period of effectiveness of the Shelf Registration Statement provided for in
     Section 2(b) above and the Exchange Offer Registration Statement provided
     for in Section 1 above shall each be extended by the number of days from
     and including the date of the giving of such notice to and including the
     date when the Initial Purchasers, the Holders of the Securities and any
     known Participating Broker-Dealer shall have received such amended or
     supplemented prospectus pursuant to this Section 3(j).

          (k)  Not later than the effective date of the applicable Registration
     Statement, the Company will provide a CUSIP number for the Initial
     Securities, the Exchange Securities or the Private Exchange Securities, as
     the case may be, and provide the applicable trustee with printed
     certificates for the Initial Securities, the Exchange Securities or the
     Private Exchange Securities, as the case may be, in a form eligible for
     deposit with The Depository Trust Company.

          (l)  The Company will comply with all rules and regulations of the
     Commission to the extent and so long as they are applicable to the
     Registered Exchange Offer or the Shelf Registration, and the will Issuer
     make generally available to its security holders (or otherwise provide
     in accordance with Section 11(a) of the Securities Act) an earnings
     statement satisfying

                                       6
<PAGE>

     the provisions of Section 11(a) of the Securities Act, no later than 45
     days after the end of a 12-month period (or 90 days, if such period is a
     fiscal year) beginning with the first month of the Issuer's first fiscal
     quarter commencing after the effective date of the Registration Statement,
     which statement shall cover such 12-month period.

          (m)  The Company shall cause the Indenture to be qualified under the
     Trust Indenture Act of 1939, as amended, in a timely manner and containing
     such changes, if any, as shall be necessary for such qualification. In the
     event that such qualification would require the appointment of a new
     trustee under the Indenture, the Company shall appoint a new trustee
     thereunder pursuant to the applicable provisions of the Indenture.

          (n)  The Company may require each Holder of Securities to be sold
     pursuant to the Shelf Registration Statement to furnish to the Company such
     information regarding the Holder and the distribution of the Securities as
     the Company may from time to time reasonably require for inclusion in the
     Shelf Registration Statement, and the Company may exclude from such
     registration the Securities of any Holder that unreasonably fails to
     furnish such information within a reasonable time after receiving such
     request.

          (o)  The Company shall enter into such customary agreements
     (including, if requested, an underwriting agreement in customary form) and
     take all such other action, if any, as any Holder of the Securities shall
     reasonably request in order to facilitate the disposition of the Securities
     pursuant to any Shelf Registration.

          (p)  In the case of any Shelf Registration, the Company shall (i) make
     reasonably available for inspection by the Holders of the Securities, any
     underwriter participating in any disposition pursuant to the Shelf
     Registration Statement and any attorney, accountant or other agent retained
     by the Holders of the Securities or any such underwriter all relevant
     financial and other records, pertinent corporate documents and properties
     of the Company and (ii) cause the Company's officers, directors, employees,
     accountants and auditors to supply all relevant information reasonably
     requested by the Holders of the Securities or any such underwriter,
     attorney, accountant or agent in connection with the Shelf Registration
     Statement, in each case, as shall be reasonably necessary to enable such
     persons, to conduct a reasonable investigation within the meaning of
     Section 11 of the Securities Act; provided, however, that the foregoing
                                       --------  -------
     inspection and information gathering shall be coordinated on behalf of the
     Initial Purchasers by you and on behalf of the other parties, by one
     counsel designated by and on behalf of such other parties as described in
     Section 4 hereof.

          (q)  In the case of any Shelf Registration, the Company, if requested
     by any Holder of Securities covered thereby, shall cause (i) its counsel to
     deliver an opinion and updates thereof relating to the Securities in
     customary form addressed to such Holders and the managing underwriters, if
     any, thereof and dated, in the case of the initial opinion, the effective
     date of such Shelf Registration Statement (it being agreed that the
     matters to be covered by such opinion shall include, without limitation,
     the due incorporation and good standing of the Company and its
     subsidiaries; the qualification of the Company and its subsidiaries to
     transact business as foreign corporations in identified jurisdictions; the
     due authorization, execution and delivery of the relevant agreement of the
     type referred to in Section 3(o) hereof; the due authorization, execution,
     authentication and issuance, and the validity and enforceability, of the
     applicable Securities; the absence of material legal or governmental
     proceedings involving the Company and its subsidiaries; the absence of
     governmental approvals required to be obtained in connection with the Shelf
     Registration Statement, the offering and sale of the applicable Securities,
     or any agreement of the type referred to in Section 3(o) hereof; the
     compliance as to form of such Shelf Registration Statement and any
     documents incorporated by reference therein and of the Indenture with the
     requirements of the Securities Act and the Trust Indenture Act,
     respectively; and, as of the date of the opinion and as of the effective
     date of the Shelf Registration Statement or most recent post-effective
     amendment thereto, as the case may be, the absence from such Shelf
     Registration Statement and the prospectus included therein, as then amended
     or supplemented, and from any documents incorporated by reference therein
     of an untrue statement of a material fact or the omission to state therein
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading (in the case of any such documents, in
     the light of the circumstances existing at the time that such documents
     were filed with the Commission under the Exchange Act); (ii) its officers
     to execute and deliver all customary documents and certificates and updates
     thereof requested by any underwriters of the applicable Securities and
     (iii) its independent public accountants and the independent public
     accountants with respect to any other entity for which financial
     information is provided in the

<PAGE>

     Shelf Registration Statement to provide to the selling Holders of the
     applicable Securities and any underwriter therefor a comfort letter in
     customary form and covering matters of the type customarily covered in
     comfort letters in connection with primary underwritten offerings,
     subject to receipt of appropriate documentation as contemplated and, only
     if permitted, by Statement of Auditing Standards No. 72.

          (r)  In the case of the Registered Exchange Offer, if requested by any
     Initial Purchaser or any known Participating Broker-Dealer, the Company
     shall cause (i) its counsel to deliver to such Initial Purchaser or such
     Participating Broker-Dealer a signed opinion in the form set forth in
     Sections 6(e) and 6(f) of the Purchase Agreement with such changes as are
     customary in connection with the preparation of a Registration Statement
     and (ii) its independent public accountants and the independent public
     accountants with respect to any other entity for which financial
     information is provided in the Registration Statement to deliver to such
     Initial Purchaser or such Participating Broker-Dealer a comfort letter, in
     customary form, meeting the requirements as to the substance thereof as set
     forth in Section 6(a) of the Purchase Agreement, with appropriate date
     changes.

          (s)  If a Registered Exchange Offer or a Private Exchange is to be
     consummated, upon delivery of the Initial Securities by Holders to the
     Issuer (or to such other Person as directed by the Issuer) in exchange for
     the Exchange Securities or the Private Exchange Securities, as the case may
     be, the Issuer shall mark, or cause to be marked, on the Initial Securities
     so exchanged that such Initial Securities are being canceled in exchange
     for the Exchange Securities or the Private Exchange Securities, as the case
     may be; in no event shall the Initial Securities be marked as paid or
     otherwise satisfied.

          (t)  The Issuer will use its best efforts to (a) if the Initial
     Securities have been rated prior to the initial sale of such Initial
     Securities, confirm such ratings will apply to the Securities covered by a
     Registration Statement, or (b) if the Initial Securities were not
     previously rated, cause the Securities covered by a Registration Statement
     to be rated with the appropriate rating agencies, if so requested by
     Holders of a majority in aggregate principal amount of Securities covered
     by such Registration Statement, or by the managing underwriters, if any.

          (u)  In the event that any broker-dealer registered under the Exchange
     Act shall underwrite any Securities or participate as a member of an
     underwriting syndicate or selling group or "assist in the distribution"
     (within the meaning of the Conduct Rules (the "Rules") of the National
     Association of Securities Dealers, Inc. ("NASD")) thereof, whether as a
     Holder of such Securities or as an underwriter, a placement or sales agent
     or a broker or dealer in respect thereof, or otherwise, the Company will
     assist such broker-dealer in complying with the requirements of such
     Rules, including, without limitation, by (i) if such Rules, including Rule
     2720, shall so require, engaging a "qualified independent underwriter" (as
     defined in Rule 2720) to participate in the preparation of the Registration
     Statement relating to such Securities, to exercise usual standards of due
     diligence in respect thereto and, if any portion of the offering
     contemplated by such Registration Statement is an underwritten offering or
     is made through a placement or sales agent, to recommend the yield of such
     Securities, (ii) indemnifying any such qualified independent underwriter to
     the extent of the indemnification of underwriters provided in Section 5
     hereof and (iii) providing such information to such broker-dealer as may be
     required in order for such broker-dealer to comply with the requirements
     of the Rules.

          (v)  The Company shall use its best efforts to take all other steps
     necessary to effect the registration of the Securities covered by a
     Registration Statement contemplated hereby.

     4.  Registration Expenses.  (a) All expenses incident to the Company's

     for the Initial Purchasers, incurred in connection with the Registered
     Exchange Offer;

          (v)   all application and filing fees in connection with listing the

          (vi)  all fees and disbursements of independent certified public
     accountants of the Company (including the expenses of any special audit and
     comfort letters required by or incident to such performance).

The Company will bear its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal or
accounting duties), the expenses of any annual audit and the fees and expenses
of any person, including special experts, retained by the Company.

     (b)  In connection with any Registration Statement required by this
Agreement, the Company will reimburse the Initial Purchasers and the Holders of

amount of the Transfer Restricted Securities for whose benefit such Registration
Statement is being prepared.

     5.   Indemnification.  (a)  The Company agrees to indemnify and hold
harmless each Holder of the Securities, any Participating Broker-Dealer and
each person, if any, who controls such Holder or such Participating Broker-
Dealer within the meaning of the Securities Act or the Exchange Act (each
Holder, any Participating Broker-Dealer and such controlling persons are
referred to collectively as the "Indemnified Parties") from and against any
losses, claims, damages or liabilities, joint or several, or any actions in
respect thereof (including, but not limited to, any losses, claims, damages,
liabilities or actions relating to purchases and sales of the Securities) to
which each Indemnified Party may become subject under the Securities Act, the
Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities
or actions arise out of or are based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in a Registration Statement or
prospectus or in any amendment or supplement thereto or in any preliminary
prospectus relating to a Shelf Registration, or (ii) the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and shall reimburse, as
incurred, the Indemnified Parties for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability or action in respect thereof; provided, however, that
                                                       --------  -------
(i) the Company shall not be liable in any such case to the extent that such
loss, claim, damage or liability arises out of or is based upon any untrue
statement or alleged untrue statement or omission or alleged omission made in a
Registration Statement or prospectus or in any amendment or supplement thereto
or in any preliminary prospectus relating to a Shelf Registration in reliance
upon and in conformity with written information pertaining to such Holder and
furnished to the Company by or on behalf of such Holder specifically for
inclusion therein and (ii) with respect to any untrue statement or omission or
alleged untrue statement or omission made in any preliminary prospectus relating
to a Shelf Registration Statement, the indemnity agreement contained in this
subsection (a) shall not inure to the benefit of any Holder or Participating
Broker-Dealer from whom the person asserting any such losses, claims, damages or
liabilities purchased the Securities concerned, to the extent that a prospectus
relating to such Securities was required to be delivered by such Holder or
Participating Broker-Dealer under the Securities Act in connection with such
purchase and any such loss, claim, damage or liability of such Holder or
Participating Broker-Dealer results from the fact that there was not sent or
given to such person, at or prior to the written confirmation of the sale of
such Securities to such person, a copy of the final prospectus if the Company
had previously furnished copies thereof to such Holder or Participating Broker-
Dealer; provided further, however, that this indemnity agreement will be in
        -------- -------  -------
addition to any liability which the Company may otherwise have to such
Indemnified Party. The Company shall also indemnify underwriters, their officers
and directors and each person who controls such underwriters within the meaning
of the Securities Act or the Exchange Act to the same extent as provided above
with respect to the indemnification of the Holders of the Securities if
requested by such Holders.

     (b)  Each Holder of the Securities, severally and not jointly, will
indemnify and hold harmless the Company and each person, if any, who controls
the Company within the meaning of the Securities Act or the Exchange Act from
and against any losses, claims, damages or liabilities or any actions in

                                       9
<PAGE>

respect thereof, to which the Company or any such controlling person may become
subject under the Securities Act, the Exchange Act or otherwise, insofar as such
losses, claims, damages, liabilities or actions arise out of or are based upon
(i) any untrue statement or alleged untrue statement of a material fact
contained in a Registration Statement or prospectus or in any amendment or
supplement thereto or in any preliminary prospectus relating to a Shelf
Registration, or (ii) the omission or alleged omission to state therein a
material fact necessary to make the statements therein not misleading, but in
each case only to the extent that the untrue statement or omission or alleged
untrue statement or omission was made in reliance upon and in conformity with
written information pertaining to such Holder and furnished to the Company by or
on behalf of such Holder specifically for inclusion therein; and, subject to the
limitation set forth immediately preceding this clause, shall reimburse, as
incurred, the Company for any legal or other expenses reasonably incurred by the
Company or any such controlling person in connection with investigating or
defending any loss, claim, damage, liability or action in respect thereof. This
indemnity agreement will be in addition to any liability which such Holder may
otherwise have to the Company or any of its controlling persons.

     (c)  Promptly after receipt by an indemnified party under this Section 5
of notice of the commencement of any action or proceeding (including a
governmental investigation), such indemnified party will, if a claim in respect
thereof is to be made against the indemnifying party under this Section 5,
notify the indemnifying party of the commencement thereof; but the omission so
to notify the indemnifying party will not, in any event, relieve the
indemnifying party from any obligations to any indemnified party other than the
indemnification obligation provided in paragraph (a) or (b) above. In case any
such action is brought against any indemnified party, and it notifies the
indemnifying party of the commencement there of, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to t he
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof the
indemnifying party will not be liable to such indemnified party under this
Section 5 for any legal or other expenses, other than reasonable costs of
investigation, subsequently incurred by such indemnified party in connection
with the defense thereof. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action, and does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

     (d)  If the indemnification provided for in this Section 5 is unavailable
or insufficient to hold harmless an indemnified party under subsections (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to in subsection (a) or (b)
above in such proportion as is appropriate to reflect the relative fault of the
indemnifying party or parties on the one hand and the indemnified party on the
other in connection with the statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof) as well
as any other relevant equitable considerations. The relative fault of the
parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or such Holder or such other indemnified party, as the case may
be, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The amount paid by an indemnified party as a result of the losses, claims,
damages or liabilities referred to in the first sentence of this subsection (d)
shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any action
or claim which is the subject of this subsection (d). Notwithstanding any other
provision of this Section 5(d), the Holders of the Securities shall not be
required to contribute any amount in excess of the amount by which the net
proceeds received by such Holders from the sale of the Securities pursuant to a
Registration Statement exceeds the amount of dam ages which such Holders have
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. For purposes of this paragraph (d), each person,
if any, who controls such indemnified party within the meaning of the Securities
Act or the Exchange Act shall have the same rights to contribution as such
indemnified party and each person, if any, who controls the Company within the
meaning of the Securities Act or the Exchange Act shall have the same rights to
contribution as the Company.

                                       10

     (e)  The agreements contained in this Section 5 shall survive the sale of
the Securities pursuant to a Registration Statement and shall remain in full
force and effect, regardless of any termination or cancellation of this
Agreement or any investigation made by or on behalf of any indemnified party.

     6.   Additional Interest Under Certain Circumstances.  (a)  Additional
interest (the "Additional Interest") with respect to the Securities shall be
assessed as follows if any of the following events occur (each such event in
clauses (i) through (iv) below a "Registration Default"):

     (i)    any Registration Statement required by this Agreement is not filed
            with the Commission on or prior to the applicable Filing Deadline;

     (ii)   any Registration Statement required by this Agreement is not
            declared effective by the Commission on or prior to the applicable
            Effectiveness Deadline;

     (iii)  the Registered Exchange Offer has not been consummated on or prior
            to the Consummation Deadline; or

     (iv)   any Registration Statement required by this Agreement has been
            declared effective by the Commission but (A) such Registration
            Statement thereafter ceases to be effective or (B) such Registration
            Statement or the related prospectus ceases to be usable in
            connection with resales of Transfer Restricted Securities during the
            periods specified herein because either (1) any event occurs as a
            result of which the related prospectus forming part of such
            Registration Statement would include any untrue statement of a
            material fact or omit to state any material fact necessary to make
            the statements therein in the light of the circumstances under which
            they were made not misleading, or (2) it shall be necessary to amend
            such Registration Statement or supplement the related prospectus, to
            comply with the Securities Act or the Exchange Act or the respective
            rules thereunder.

Each of the foregoing will constitute a Registration Default whatever the
reason for any such event and whether it is voluntary or involuntary or is
beyond the control of the Company or pursuant to operation of law or as a result
of any action or inaction by the Commission.

     Additional Interest shall accrue on the Initial Securities and the Private
Exchange Securities over and above the interest set forth in the title of the
Securities from and including the date on which any such Registration Default
shall occur to but excluding the date on which all such Registration Defaults
have been cured, at a rate of 0.50% per annum (the "Additional Interest Rate")
for the first 90-day period immediately following the occurrence of such
Registration Default.  The Additional Interest Rate shall increase by an
additional 0.50% per annum with respect to each subsequent 90-day period until
all Registration Defaults have been cured, up to a maximum Additional Interest
Rate of 1.0% per annum.

     (b)  A Registration Default referred to in Section 6(a)(iv) hereof shall be
deem ed not to have occurred and be continuing in relation to a Shelf
Registration Statement or the related prospectus if (i) such Registration
Default has occurred solely as a result of (x) the filing of a post-effective
amendment to such Shelf Registration Statement to incorporate annual audited
financial information with respect to the Company where such post-effective
amendment is not yet effective and needs to be declared effective to permit
Holders to use the related prospectus or (y) other material events, with respect
to the Company that would need to be described in such Shelf Registration
Statement or the related prospectus and (ii) in the case of clause (y), the
Company is proceeding promptly and in good faith to amend or supplement such
Shelf Registration Statement and related prospectus to describe such events;
provided, however, that in any case if such Registration Default   occurs for a
--------  -------
continuous period in excess of 30 days, Additional Interest shall be payable in
accordance with the above paragraph from the day such Registration Default
occurs until the date on which such Registration Default is cured.

     (c)  Any amounts of Additional Interest due pursuant to Section 6(a) will
be payable in cash on the regular interest payment dates with respect to the
Securities. The amount of Additional Interest will be determined by multiplying
the applicable Additional Interest Rate by the principal amount of the Initial
Securities or Private Exchange Securities, as the case may be, and further
multiplied by a fraction, the numerator of which is the number of days such
Additional Interest Rate was applicable during such period (determined on the
basis of a 360-day year comprised of twelve 30-day months), and the denominator
of which is 360.

     (d)  "Transfer Restricted Securities" means each Security until (i) the
date on which such Security has been exchanged by a person other than a broker-
dealer for a freely transferable Exchange

                                       11
<PAGE>

Security in the Registered Exchange Offer, (ii) following the exchange by a
broker-dealer in the Registered Exchange Offer of an Initial Security for an
Exchange Security, the date on which such Exchange Security is sold to a
purchaser who receives from such broker-dealer on or prior to the date of such
sale a copy of the prospectus contained in the Exchange Offer Registration
Statement, (iii) the date on which such Security has been effectively registered
under the Securities Act and disposed of in accordance with the Shelf
Registration Statement or (iv) the date on which such Security is distributed to
the public pursuant to Rule 144 under the Securities Act or is saleable pursuant
to Rule 144(k) under the Securities Act.

     7.   Rules 144 and 144A. The Company shall use its best efforts to file the
reports required to be filed by it under the Securities Act and the Exchange Act
in a timely manner and, if at any tim e the Company is not required to file such
reports, it will, upon the request of any Holder of Transfer Restricted
Securities, make publicly a vailable other information so long as necessary to
permit sale s of their securities pursuant to Rules 144 and 144A. The Company
covenants that it will take such further action as any Holder of Transfer
Restricted Securities may reasonably request, all to the extent required from
time to time to enable such Holder to sell Transfer Restricted Securities
without registration under the Securities Act within the limitation of the
exemptions provided by Rules 144 and 144A (including the requirements of Rule
144A(d)(4)). The Issuer will provide a copy of this Agreement to prospective
purchasers of Initial Securities identified to the Issuer by the Initial
Purchasers upon request. Upon the request of any Holder of Initial Securities,
the Issuer shall deliver to such Holder a written statement as to whether it has
complied with such requirements. Notwithstanding the foregoing, nothing in this
Section 7 shall be deemed to require the Company to register any of its
securities pursuant to the Exchange Act.

     8.   Underwritten Registrations.  If any of the Transfer Restricted
Securities covered by any Shelf Registration are to be sold in an underwritten
offering, the investment banker or investment bankers and manager or managers
that will administer the offering ("Managing Underwriters") will be selected by
the Holders of a majority in aggregate principal a mount of such Transfer
Restricted Securities to be included in such offering.

     No person may participate in any underwritten registration hereunder unless
such person (i) agrees to sell such person's Transfer Restricted Securities on
the basis reasonably provided in any underwriting arrangements approved by the
persons entitled hereunder to approve such arrangements and (ii) completes and
executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under t he terms of such
underwriting arrangements.

     9.   Miscellaneous.

     (a)  Remedies.  The Company acknowledges and agrees that any failure by the
Company to comply with its obligations under Section 1 and 2 hereof may result
in material irreparable injury to the Initial Purchasers or the Holders for
which there is no adequate remedy at law, that it will not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, the Initial Purchasers or any Holder may obtain such relief as may be
required to specifically enforce the Company's obligations under Sections 1 and
2 hereof. The Company further agree s to waive the defense in any action for
specific performance that a remedy at law would be adequate.

     (b)  No Inconsistent Agreements.  The Company will not on or after the date
of this Agreement enter into any agreement with respect to its securit ies that
is inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof.  The rights granted to the
Holders hereunder do not in any way conflict with and are not inconsistent with
the rights granted to the holders of the Company's securities under any
agreement in effect on the date hereof.

     (c)  Amendments and Waivers.  The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to departures from
the provisions hereof may not be given, except by the Company and the written
consent of the Holders of a majority in principal amount of the Securities
affected by such amendment, modification, supplement, waiver or consents.

     The Company will not receive any proceeds from any sale of Exchange
Securities by broker-dealers. Exchange Securities receive d by broker-dealers
for their own account pursuant to the Exchange Offer may be sold from time to
time in one or more transactions in the over-the-counter market, in negotiated
transactions, through the writing of options on the Exchange Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices. Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such Exchange
Securities. Any broker-dealer that resells Exchange Securit ies that were
received by it for its own account pursuant to the Exchange Offer and any broker
or dealer that participates in a distribution of such Exchange Securities may
be deemed to be an "underwriter" within the meaning of the Securities Act and
any profit on any such resale of Exchange Securities and any commission or
concessions received by any such persons may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that,
by acknowledging that it will deliver and by delivering a prospectus, a broker-
dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

     For a period of 180 days after the Expiration Date the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
Holders of the Securities) other than commissions or concessions of any brokers
or dealers and will indemnify the Holders of the Securities (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.

               Registration Rights Agreement dated as of June 28, 2000, among
               Morrison Knudson Corporation, a Delaware corporation (the
               "Company"), each of the subsidiaries listed on Schedule A thereto
               (each such subsidiary individually, a "Guarantor" and
               collectively, the "Guarantors"), and Credit Suisse First Boston
               Corporation, BMO Nesbitt Burns Corp., and U.S. Bancorp Libra, a
               division of U.S. Bancorp Investments, Inc. (the "Purchasers").

     A.  Capitalized terms used herein and not otherwise defined herein shall
have the meanings assigned to such terms in the Registration Rights Agreement.

     B. The Guarantors have entered into the Registration Rights Agreement in
order to induce the Purchasers to purchase the Notes. Pursuant to Section 6(k)
of the Purchase Agreement dated as of June 28, 2000, among the Company, the
Guarantors and the Purchasers, as amended, each subsidiary of the Company as of
the Closing Date listed in the footnote to Schedule A to the Registration Rights
Agreement is required to become a party to the Registration Rights Agreement as
a Guarantor by execution and delivery of an instrument in the form of this
Amendment. The undersigned subsidiaries of the Company (the "New Guarantors")
are executing this Amendment in accordance with the requirements of the Purchase
Agreement to become a party to the Registration Rights Agreement.

     Accordingly, the Company, the New Guarantors and the Purchasers agree as
follows:

     SECTION 1. Each New Guarantor by its signature below becomes a party to the
Registration Rights Agreement with the same force and effect as if originally
named therein as a Guarantor, and each New Guarantor hereby agrees to all the
terms and provisions of the Registration Rights Agreement applicable to it as a
Guarantor thereunder. Each reference to a "Guarantor" in the Registration Rights
Agreement shall be deemed to include each New Guarantor. The Registration Rights
Agreement is hereby incorporated herein by reference.

     SECTION 2. Each New Guarantor represents and warrants to the Purchasers
that this Amendment has been duly authorized, executed and delivered by it and
constitutes its legal, valid and binding obligation, enforceable against it in
accordance with its terms.

     SECTION 3. This Amendment may be executed in counterparts, each of which
shall constitute an original, but all of which when taken together shall
constitute a single contract. Delivery of an executed signature page to this
Amendment by facsimile transmission shall be as effective as delivery of a
manually executed counterpart of this Amendment.

     SECTION 4. Except as expressly amended hereby, the Registration Rights
Agreement shall remain in full force and effect.

     SECTION 5. THIS AMENDMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAWS OF THE STATE OF NEW YORK.

     SECTION 6. In case any one or more of the provisions contained in this
Amendment should be held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein and in the Registration Rights Agreement shall not in any way be affected
or impaired thereby (it being understood that the

invalidity of a particular provision hereof in a particular jurisdiction shall
not in and of itself affect the validity of such provision in any other
jurisdiction). The parties hereto 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 7.  All communications and notices hereunder shall be in writing
and given as provided in Section 9(d) of the Registration Rights Agreement.  All
communications and notices hereunder to any New Guarantor shall be given to it
at the address set forth in Section 9(d) of the Registration Rights Agreement.

     IN WITNESS WHEREOF, the Company, the New Guarantors and the Purchasers have
duly executed this Amendment to the Registration Rights Agreement as of the day
and year first above written.
