Amendments.  Subject to the satisfaction of the conditions precedent set forth in Section 3 hereof, as of the date hereof:

(a)

The definition of Consolidated EBITDDA appearing in Section 1.01 of the Credit Agreement is hereby amended to read as follows:

“Consolidated EBITDDA” means, for any period, as applied to the Borrower and its consolidated Subsidiaries without duplication, the sum of the amounts for such period of: (i) Consolidated Net Income, plus (ii) the following to the extent deducted in calculating such Consolidated Net Income:  (a) Consolidated Interest Expense, (b) all federal and state income tax expense, (c) all depreciation, depletion and amortization expense, (d) any non-cash asset impairments or restructuring charges (other than any non-cash charges to the extent that such charge represents an accrual of or reserve for a future cash payment), including non-cash charges related to the vesting of performance unit and equity-based compensation plans in connection with any change of control, (e) solely for the four fiscal quarter period ending June 30, 2014, actual cash restructuring charges (including proxy-related settlement charges) of up to $8.0 million, and (f) actual cash proxy defense-related expenses in an aggregate amount not to exceed $2.0 million during such period, all of the foregoing as determined and computed on a Consolidated basis in accordance with GAAP.

1

CHAR1\136298v3

(i) On or prior to July 28, 2014 (or such later date as agreed by the Administrative Agent in its sole discretion), obtain approval from the Borrower’s board of directors to cause the Obligations to be secured by Liens on substantially all of the assets of the Loan Parties; and (ii) on or prior to August 27, 2014 (or such later date as agreed by the Required Lenders in their sole discretion), pursuant to documentation acceptable to the Administrative Agent (including, but not limited to an amendment to this Agreement and an intercreditor agreement with the noteholders under the 2010 Note Agreement), cause the Obligations to be secured by Liens on substantially all of the assets of the Loan Parties.

(c)

Section 7.01(c) of the Credit Agreement is hereby amended to read as follows:

(c)

Minimum Net Worth.  The Loan Parties will not at any time permit Consolidated Net Worth to be less than the sum of (i) $220,000,000, plus (ii) an amount equal to 25% of Consolidated Net Income for each fiscal quarter of the Borrower ending on or after September 30, 2014 (with no deduction for a net loss in any such fiscal quarter), such amount to be increased on a cumulative basis as of the end of each fiscal quarter, plus (iii) 100% of the proceeds of the issuance of all Equity Interests after June 30, 2014.  The calculation of Consolidated Net Worth for purposes of this Section 7.01(c) (only) shall be adjusted to exclude (1) all “accumulated other comprehensive income or loss” as shown on the Borrower’s consolidated balance sheet (i.e., there will be added back to Consolidated Net Worth any such amount that is shown as a negative number and there will be subtracted from Consolidated Net Worth any such amount that is shown as a positive number); provided, however, that the aggregate amount of all such amounts added back to Consolidated Net Worth pursuant to this sentence during the term of this Agreement shall not exceed $70,000,000 and (2) non-cash restructuring charges incurred after the date of this Agreement and prior to March 31, 2014 in an aggregate amount not to exceed $40,000,000 (i.e., such non-cash restructuring charges shall be added back to Consolidated Net Worth).
