          (v) the events of default and covenants applicable to such
          Indebtedness shall not be more restrictive, in any material respect,

          hereafter, to the Agent or any Bank to secure the payment or
          performance of any or all of the Obligations and, in the event any
          such Lien is provided, such indenture and any amendment, restatement,
          modification, supplement, refinancing, or the like thereto or thereof
          shall not require Borrower or any of its Subsidiaries to provide any
          Lien to secure payment or performance of any obligation arising under
          such indenture or any amendment, restatement, modification,
          supplement, refinancing, or the like thereto or thereof;

          with respect to such Indebtedness and such documents shall be
          reasonably acceptable to the Agent based upon the requirements of this
          definition of Permitted Note Indenture.

          The Loan Parties shall promptly after the issuance of such
          Indebtedness deliver to the Agent and the Banks a copy of the material
          documents with respect to the issuance of such Indebtedness.

     the one-hundred eightieth (180th) day after an Asset Disposition or Equity
     Disposition or on the two hundred seventieth (270th) day after a Casualty
     Disposition, to any unconsummated acquisition of additional or replacement
     assets."

     (b) Permitted Indebtedness. (i) Section 8.2.1(v) is hereby amended and
restated in its entirety as follows:

          "(v) Unsecured Indebtedness of a domestic Loan Party to another

     8.2.1 of the Credit Agreement:

          "; and

          (x) Indebtedness arising under the Permitted Note Indenture."

     (c) Negative Pledges. The reference to Section 8.2.1(v)(B) in the first
sentence of Section 8.2.8 is hereby changed to be a reference to Section
8.2.1(x), and the Loan Parties acknowledge and agree the reference to
"Indentures or any permitted refinancings thereof" does not include the
Permitted Note Indenture.

     (d) Contemporaneous Prepayment, Reduction of Commitments. Upon receipt of
proceeds arising from the Permitted Indenture Notes (or any similar notes which
would be Permitted Indenture Notes but for the failure to meet one or more of

Revolving Credit Commitments shall permanently and irrevocably be reduced to an

deleted and replaced in its entirety with Schedule 1.1(B) hereto.

     (e) Prepayments. The following Section 5.5 is hereby added to the Credit
Agreement:

          5.5 Mandatory Prepayments.

               5.5.1 Mandatory Prepayment Upon Significant Disposition.

               Within one-hundred eighty (180) days of an Asset Disposition or
          Equity Disposition and within two hundred seventy (270) days of a
          Casualty Disposition, Borrower shall prepay the principal amount of
          the Committed Loans and Bid Loans outstanding and cash collateralize
          the Letters of Credit Outstanding (in the order and manner set forth
          below in Section 5.5.2) in an aggregate amount equal to the
          Significant Disposition Amount; provided, however, that in the event
          that there are no outstanding Committed Loans or Bid Loans and there
          are no Letters of Credit Outstanding or in the event that the sum of
          the

                                       4

<PAGE>

          outstanding Committed Loans, Bid Loans, and Letters of Credit
          Outstanding is less than the Significant Disposition Amount, Borrower
          shall prepay all Committed Loans and Bid Loans outstanding and cash
          collateralize all Letters of Credit Outstanding (in the manner set
          forth below) within one-hundred eighty (180) days of an Asset
          Disposition or Equity Disposition and within two hundred seventy (270)
          days of a Casualty Disposition, as the case may be. Any prepayment
          hereunder shall be subject to the Borrower's obligation to indemnify
          the Lenders under Section 5.6.2 [Indemnity].

               5.5.2 Application Among Loans and Interest Rate Options; Cash
          Collateral Under Certain Circumstances.

               All prepayments and cash collateral required pursuant to this
          Section 5.5 shall: (a) first be applied to prepay Committed Loans and,
          as among the Interest Rate Options applicable to Committed Loans,
          first to the principal amount of the Committed Loans subject to the
          Base Rate Option, then to Committed Loans subject to a Committed Loan
          Euro-Rate Option then to Committed Loans subject to an interest rate
          based upon a Cost of Funds Rate; (b) second be deposited by Borrower
          in a non-interest bearing account with the Agent, as cash collateral
          for the Obligations, in an amount equal to the lesser of the amount of
          the Letters of Credit Outstanding or the balance of the amount
          remaining for prepayment or cash collateral pursuant to this Section
          5.5 after application of the prepayment amount pursuant to Clause (a)
          directly above, and the Borrower hereby pledges to the Agent and the
          Banks, and grants to the Agent and the Banks a security interest in,
          all such cash and deposits as security for such Obligations; and (c)
          third be applied to Bid Loans and, if more than one, pro ratably as
          among all Bid Loans (subject to any Bid Loan lender having the option
          to elect not to receive prepayment of its Bid Loan). Upon and to the
          extent of the expiration of, or the payment by Borrower (by way of
          Revolving Credit Loans or otherwise) of the Reimbursement Obligations
          relating to, Letters of Credit Outstanding that are cash
          collateralized pursuant to this Section 5.5, such cash collateral
          shall to such extent be released and returned to the Borrower upon its
          request except to the extent any such cash collateral is utilized to
          pay any such Reimbursement Obligations.

     (f) Release of Canadian Subsidiary from Guaranty. At the request of
Borrower in connection with the Permitted Note Indenture and in light of the
representation and warranty of Borrower set forth at Section 2.05 below, the
Agent on behalf of the Banks and itself hereby releases Wabtec Railway
