Subsidiaries, plus the discount or yield in respect of Invested Amounts, plus
the amount of dividends paid by the Company for the period of time under

giving pro forma effect thereto as if such acquisition occurred on the first day
of such period

     “Public Debt Rating” means, as of any date, the lowest rating that has been
most recently announced by either S&P or Moody’s, as the case may be, for any
class of non-credit enhanced long-term senior unsecured debt issued by the

have in effect a Public Debt Rating, the Applicable Margin and the Applicable
Percentage shall be determined assuming that the other rating agency’s rating is
set at the same level; (b) if neither S&P nor Moody’s shall have in effect a
Public Debt Rating, the Applicable Margin and the Applicable Percentage shall be
set in accordance with Level 5 under the definition of “Applicable Margin” or
“Applicable Percentage”, as the case may be; (c) if the ratings established by
S&P and Moody’s shall fall within different levels, the Applicable Margin and
the Applicable Percentage shall be based upon the higher rating, provided that
if the

lower of such ratings is more than one level below the higher of such ratings,
the Applicable Margin and the Applicable Percentage will be determined based on
the level immediately above the lower of such ratings; (d) if any rating
established by S&P or Moody’s shall be changed, such change shall be effective
as of the date on which such change is first announced publicly by the rating
agency making such change; and (e) if S&P or Moody’s shall change the basis on
which ratings are established, each reference to the Public Debt Rating
announced by S&P or Moody’s, as the case may be, shall refer to the then
equivalent rating by S&P or Moody’s, as the case may be.

     “Total Consolidated Debt” means all Debt that would, in accordance with
GAAP, appear on the Consolidated balance sheet of the Company and its
Subsidiaries and all Invested Amounts; provided, however, to the extent that the
Company has incurred new Debt (other than any Debt incurred pursuant to this
Agreement), and maintains cash or cash equivalents on hand in the amount of such
new Debt, in each case in an amount sufficient for the payment of all or a
portion of the outstanding 5.50% senior notes due October 1, 2010, all or such
portion of the outstanding 5.50% senior notes shall be excluded from the
calculation of Consolidated Debt for all reporting periods prior to October 1,

rationalization of manufacturing capacity and similar actions payable as a
direct result of restructuring initiatives”.

     (d) The definition of “Termination Date” in Section 1.01 of the Credit
Agreement is hereby amended by (i) deleting “earlier” and substituting
“earliest” in lieu thereof, (ii) deleting the “and” immediately preceding the
“(b)” and replacing it with a “,” and (iii) adding immediately after the phrase
“Section 2.05 or 6.01” the following: “and (c) as to any Lender who becomes an
Affected Lender, the date of termination of such Affected Lender’s Commitments
pursuant to Section 2.05(b)”.

     (e) Section 1.01 of the Credit Agreement is hereby amended by inserting the
following new defined terms in the appropriate alphabetical order therein:

     “Affected Lender” means any Lender that (a) is a Defaulting Lender, (b) has
otherwise failed to pay over to the Agent or any other Lender any other amount
required to be paid by it hereunder within one Business Day of the date when
due, unless the subject of a good faith dispute or unless such failure has been
cured, or (c) is (or whose parent company is) in bankruptcy or insolvency
proceedings, has had a receiver, conservator, trustee or custodian appointed for
it, or has taken any corporate action authorizing, or indicating its consent to,

the Agent, or any Lender in writing that it does not intend to fund any of its
Commitments, (iii) has made a public statement or announcement to the effect
that it does not intend to fund or honor its commitments under agreements in
which it has committed to extend credit or (iv) failed, within three Business
Days after request by the Agent, to confirm it will comply with the terms of the
agreement relating to its obligations to fund prospective Advances and
participations in then outstanding Letters of Credit.

     “Excluded Debt” has the meaning specified in the definition of “Total
Consolidated Debt”.

“First Amendment Effective Date” means May 15, 2009.

     (f) Section 2.04(a) of the Credit Agreement hereby amended by deleting it
in its entirety and substituting in lieu thereof the following:

of each Lender (other than a Defaulting Lender) a commitment fee on the
aggregate amount of such Lender’s Unused Commitment from the First Amendment
Effective Date in the case of each Initial Lender and from the effective date
specified in the Assumption Agreement or in the Assignment and Acceptance
pursuant to which it became a Lender in the case of each other Lender until the
Termination Date applicable to such Lender at a rate per annum equal to the
Applicable Percentage in effect from time to time, payable in arrears quarterly
on the last day of each March, June, September and December, commencing June 30,
2009, and on the Termination Date applicable to each Lender.

Days’ notice to an Affected Lender (with a copy to the Agent), to terminate in
whole such Affected Lender’s Commitment. Such termination shall be effective
with respect to such Affected Lender’s Unused Commitment on the date set forth
in such notice, provided, however, that such date shall be no earlier than ten
Business Days after receipt of such notice. Upon termination of a Lender’s
Commitment under this Section 2.05(b), and notwithstanding the pro rata sharing
provisions contained in this Agreement the Company will pay all principal of,
and interest accrued to the date of such payment on, Advances owing to such
Affected Lender and pay any accrued fees payable to such Affected Lender
pursuant to the provisions of Section 2.04, and all other amounts payable to
such Affected Lender hereunder (including, but not limited to, any increased
costs or other amounts owing under Section 2.11, any indemnification for taxes
under Section 2.14, and any compensation payments due as provided in Section
9.04); and upon such payments, the obligations of such Affected Lender hereunder

its obligations under Sections 8.05, 9.08 and 9.13 shall survive such release
and discharge as to matters occurring prior to such date; and (ii) no claim that
the Company may have against such Affected Lender arising out of such Affected
Lender’s default hereunder shall be released or impaired in any way. The
aggregate amount of the Commitments of the Lenders once reduced pursuant to this

pursuant to this Section 2.05(b), the Borrowers shall pay to an Affected Lender
any principal of, or interest accrued on, the Advances owing to such Affected
Lender, then the Company shall either (x) confirm to the Agent that the
conditions set forth in Section 3.03(a) are met on and as of such date of
payment or (y) pay or cause to be paid a ratable payment of principal and
interest to all Lenders who are not Affected Lenders.

replacing the words “facility fees” contained therein with the words “commitment
fees”.

     (k) Article II of the Credit Agreement is hereby amended by inserting at
the end thereof the following new Section 2.20:

     SECTION 2.20 Defaulting Lenders. Anything contained herein to the contrary
notwithstanding, (a) to the extent permitted by applicable law, any prepayment
of the Advances shall, if the applicable Borrower so directs at the time of
making such prepayment, be applied to the Advances of Lenders (other than
Defaulting Lenders) as if such Defaulting Lenders had no Advances outstanding;
and (b) the aggregate amount of the Advances as at any date of determination
shall be calculated as if such Defaulting Lender had funded all Defaulted
Advances of such Defaulting Lender for purposes of determining the aggregate
amount of the total Commitments available to be drawn by each Borrower.

--------------------------------------------------------------------------------

     No Commitment of any Lender shall be increased or otherwise affected, and,
except as otherwise expressly provided in this Section 2.20, performance by any
Borrower or any Lender of its obligations hereunder shall not be excused or
otherwise modified as a result of any failure by a Defaulting Lender to fund or
the operation of this Section 2.20. The rights and remedies against a Defaulting
Lender under this Section 2.20 are in addition to other rights and remedies that
any Borrower, the Agent or any other Lender may have against such Defaulting
Lender with respect to any Defaulted Advance.

     (l) Section 3.03 of the Credit Agreement is hereby amended by adding the
following new paragraph at the end of the section:

Lender becomes, and during the period it remains, a Defaulting Lender, no
Issuing Bank will be required to issue any Letter of Credit or to amend any
outstanding Letter of Credit to increase the face amount thereof, alter the
drawing terms thereunder or extend the expiry date thereof unless the applicable
Issuing Bank is satisfied that any exposure that would result therefrom is
eliminated or fully covered by the Commitments of the non-Defaulting Lenders or
by cash collateralization or a combination thereof satisfactory to such Issuing
Bank.

     (m)Section 5.02(a)(v) is hereby amended by adding the following at the
