     (1) The Borrowers, the Lenders and the Agent have entered into an Amendment and Restated Five Year Credit Agreement dated as of June 7, 2007 (as amended, supplemented or otherwise modified through the date hereof, the “Credit Agreement”). Capitalized terms not otherwise defined in this Amendment have the same meanings as specified in the Credit Agreement.

     (2) The Borrowers and the Required Lenders have agreed to amend the Credit Agreement as hereinafter set forth.

     (3) The Required Lenders are, on the terms and conditions stated below, willing to grant the request of the Borrowers and the Borrowers and the Lenders have agreed to amend the Credit Agreement as hereinafter set forth.

     SECTION 1. Amendments to Credit Agreement. The Credit Agreement is, effective as of the date hereof and subject to the satisfaction of the conditions precedent set forth in Section 2 hereto, hereby amended as follows:

     (a) Section 1.01 of the Credit Agreement is hereby amended by deleting the definitions of “Applicable Margin”, “Applicable Percentage”, “Interest Expense”, “Public Debt Rating” and “Total Consolidated Debt” in their entirety and substituting in lieu thereof the following:

     “Applicable Margin” means, for any date, a percentage per annum determined by reference to the Public Debt Rating in effect on such date as set forth below:

NYDOCS02/868991.8

     “Applicable Percentage” means, as of any date, a percentage per annum determined by reference to the Public Debt Rating in effect on such date as set forth below:

     “Interest Expense” means the sum of interest on, and amortization of debt discount, in respect of Debt (other than Excluded Debt) of the Company and its 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 consideration during the periods beginning on the First Amendment Effective Date and ending on March 31, 2010. For the purposes of calculating Interest Expense for any period, if during such period the Company or any Subsidiary shall have made an acquisition, Interest Expense for such period shall be calculated after 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 Company. For purposes of the foregoing, (a) if only one of S&P and Moody’s shall 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

NYDOCS02/868991.8

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, 2010 (such senior notes described in this proviso being “Excluded Debt”).

     (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, approval of or acquiescence in any such proceeding or appointment; provided that a Lender shall not be an Affected Lender solely

The aggregate amount of the Commitments of the Lenders once reduced pursuant to this Section 2.05(b) may not be reinstated; provided further, however, that if 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.

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.

NYDOCS02/868991.8

     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.
