     Once formed, Luxco and New German Holdco will comprise a new vertical branch of the Credit Parties’ corporate structure immediately beneath GGB, and the Equity Interests of certain of the Obligors’ existing European Subsidiaries will be transferred to either Luxco or New German Holdco by the current Obligors and/or their Subsidiaries holding such Equity Interests by means of a series of third party and intercompany loans, transfers and intercompany investments.

     In particular, Borrowers have advised Agent and Lenders of the following transactions and events related to the proposed restructuring:

     (iv) Coltec intends to contribute to GGB all of the Equity Interests it holds in Holley Automotive Systems GmbH (“Holley”), a current Wholly Owned Subsidiary of Coltec, causing Holley to become a Wholly Owned Subsidiary of GGB (the “Initial Holley Stock Transfer”);

     (vi) GGB intends to transfer to Luxco all of the Equity Interests it then holds in Holley and Heilbronn, along with a note receivable owing by Heilbronn in the original principal amount of $22,320,267, thereby causing Holley and Heilbronn to become the Wholly Owned Subsidiaries of Luxco, in exchange for an investment in additional share capital and multi-currency preferred equity certificates (respectively, the “Second Holley Stock Transfer” and the “Initial Heilbronn Stock Transfer”);

     (vii) GGB Verwaltungsgesellschaft mbH intends to withdraw as the limited partner of GGB Germany GmbH & Co. KG (“GGB KG”), causing GGB KG, by operation of German law, to be merged into its general partner, Heilbronn (the “GGB KG Merger”);

     (xi) GGB intends to transfer to Luxco all of the Equity Interests it holds in CFCL, CPHL and Garlock GB, thereby causing each of CFCL, CPHL and Garlock GB to become the Wholly Owned Subsidiaries of Luxco, in exchange for an investment in additional share capital and multi-currency preferred equity certificates (respectively, the “Second CFCL Stock Transfer”, the “Second CPHL Stock Transfer” and the “Second Garlock GB Stock Transfer”, and collectively, the “Second UK Stock Transfers”);

     3. Amendments to Loan Agreement. The Loan Agreement is hereby amended as follows:

     (a) By deleting the definitions of “Base Rate”, “Federal Funds Rate” and “Required Lenders” contained in Section 1.1 of the Loan Agreement, and by substituting in lieu thereof the following new definitions, in proper alphabetical sequence:

     Base Rate — for any day, a per annum rate equal to the greater of (a) the Prime Rate for such day; (b) the Federal Funds Rate for such day, plus 0.50%; or (c) Adjusted LIBOR Rate for a 30 day interest period as determined on such day, plus 1.00%.

     Federal Funds Rate — (a) the weighted average of interest rates on overnight federal funds transactions with members of the Federal Reserve System arranged by federal funds brokers on the applicable Business Day (or on the preceding Business Day, if the applicable day is not a Business Day), as published by the Federal Reserve Bank of New York on the next Business Day; or (b) if no such rate is published on the next Business Day, the average rate (rounded up, if necessary, to the nearest 1/8 of 1%) charged to BofA on the applicable day on such transactions, as determined by Agent.

     Required Lenders — subject to Section 4.2, at any date of determination thereof, two or more Lenders having Commitments representing at least 50.1% of the aggregate Commitments at such time; provided, however, that (i) if at any time there is only one Lender hereunder, the term “Required Lenders” shall mean such Lender, (ii) if any Lender shall be in breach of any of its obligations hereunder to Borrowers or Agent, including any breach resulting from its failure to honor its Commitment in accordance with the terms of this Agreement, then, for so long as such breach continues, the term “Required Lenders” shall mean two or more Lenders (excluding each Lender that is in breach of its obligations under this Agreement) having Commitments representing at least 50.1% of the aggregate Commitments (excluding the Commitments of each Lender that is in breach of its obligations under this Agreement) at such time, and (iii) if all of the Commitments have been terminated, the term “Required Lenders” shall mean two or more Lenders (excluding each Lender that is in breach of its obligations under this Agreement) holding Loans (including Swingline Loans) representing at least 50.1% of the aggregate principal amount of Loans (including Swingline Loans) outstanding at such time.

     (b) By adding the following new definitions of “Defaulting Lender” and “Prime Rate” to Section 1.1 of the Loan Agreement, in proper alphabetical sequence:

     Defaulting Lender — any Lender that (a) fails to make any payment or provide funds to Agent or any Borrower as required

Coltec Industries Inc
and the other Borrowers and Guarantors
December 16, 2008
Page 9

hereunder or is in breach of or fails otherwise to perform its obligations under any Loan Document, and such failure is not cured within one Business Day, or (b) is the subject of any Insolvency Proceeding.

     Prime Rate — the rate of interest announced by BofA from time to time as its prime rate. Such rate is set by BofA on the basis of various factors, including its costs and desired return, general economic conditions and other factors, and is used as a reference point for pricing some loans, which may be priced at, above or below such rate. Any change in such rate announced by BofA shall take effect at the opening of business on the day specified in the public announcement of such change.

     (c) By adding a new subclause (z) to Section 2.3.1(i) of the Loan Agreement, so that Section 2.3.1(i) of the Loan Agreement reads in its entirety as follows:

     (i) Issuing Bank shall have no obligation to issue any Letter of Credit unless (x) at least 3 Business Days prior to the date of issuance of a Letter of Credit, Issuing Bank receives an LC Request, LC Application and such other instruments and agreements as Issuing Bank may customarily require for the issuance of a letter of credit of equivalent type and amount as the requested Letter of Credit, (y) each of the LC Conditions is satisfied on the date of Issuing Bank’s receipt of the LC Request and at the time of the requested issuance of a Letter of Credit, and (z) if a Defaulting Lender exists, such Lender or Borrowers have entered into arrangements satisfactory to Agent and Issuing Bank to eliminate any funding risk associated with the Defaulting Lender. If Issuing Bank shall have received written notice from a Lender on or before the Business Day immediately prior to the date of Issuing Bank’s issuance of a Letter of Credit that one or more of the conditions set forth in Section 11 has not been satisfied, Issuing Bank shall have no obligation to issue the requested Letter of Credit or any other Letter of Credit until such notice is withdrawn in writing by that Lender or until the Required Lenders shall have effectively waived such condition in accordance with this Agreement. In no event shall Issuing Bank be deemed to have notice or knowledge of any existence of any Default or Event of Default or the failure of any conditions in Section 11 to be satisfied prior to its receipt of such notice from a Lender.

     (d) By adding the following new sentence to the end of Section 2.3.3 of the Loan Agreement:

Notwithstanding the foregoing, Borrowers shall, on demand by Issuing Bank or Agent from time to time, Cash Collateralize the LC Obligations of any Defaulting Lender.

December 16, 2008
Page 10

     (e) By deleting Section 4.2 of the Loan Agreement, and by substituting in lieu thereof the following new Section 4.2:

     4.2 Defaulting Lender. Agent may (but shall not be required to), in its discretion, retain any payments or other funds received by Agent that are to be provided to a Defaulting Lender hereunder, and may apply such funds to such Lender’s defaulted obligations or readvance the funds to Borrowers in accordance with this Agreement. The failure of any Lender to fund a Loan, to make any payment in respect of LC Obligations or to otherwise perform its obligations hereunder shall not relieve any other Lender of its obligations, and no Lender shall be responsible for default by another Lender. Lenders and Agent agree (which agreement is solely among them, and not for the benefit of or enforceable by any Borrower) that, solely for purposes of determining a Defaulting Lender’s right to vote on matters relating to the Loan Documents and to share in payments, fees and Collateral proceeds thereunder, a Defaulting Lender shall not be deemed to be a “Lender” until all its defaulted obligations have been cured.

     (f) By deleting Section 13.17 of the Loan Agreement, and by substituting in lieu thereof the following new Section 13.17:

     13.17 Replacement of Certain Lenders. If a Lender (a) is a Defaulting Lender, or (b) (i) requested compensation from Borrowers under Section 3.7 or 3.8 to recover increased costs incurred by such Lender (or its parent or holding company) or restore a rate of return on capital which are not being incurred and requested generally by the other Lenders (or their respective parents or holding companies), (ii) delivered a notice pursuant to Section 3.6 claiming that such Lender is unable to extend LIBOR Loans to Borrowers for reasons not generally applicable to the other Lenders, (iii) defaulted in paying or performing any of its obligations to Agent, or (iv) failed (within 5 Business Days after Agent’s request) or refused to give its consent to any amendment, waiver or action for which consent of all of the Lenders is required and in respect of which the Required Lenders have consented, then, in any such case and in addition to any other rights and remedies that Agent, any other Lender or Borrowers may have against such Lender, any Borrower or Agent may, by notice to such Lender within 120 days after such event (with a copy to Agent in the case of a demand by Borrowers and a copy to Borrowers in the case of a demand by Agent), require such Lender to assign all of its rights and obligations under the Loan Documents to Eligible Assignee(s) specified by Agent, pursuant to appropriate Assignment and Acceptance(s) and within 20 days after Agent’s (or Borrowers’) notice. Agent is irrevocably appointed as attorney-in-fact to execute any such Assignment and Acceptance if the Lender fails to execute same. Such Lender shall be entitled to receive, in cash, concurrently with such assignment, all amounts owed to it under the

Loan Documents, including all principal, interest and fees through the date of assignment (but excluding any prepayment charge).
