Permitted TEU Notes) or (b) to the extent any such amendment, modification or waiver does not amend, modify or waive the purchase contract agreement and/or indenture, as applicable, governing such Permitted Tangible Equity Units, Permitted TEU Purchase Contracts or Permitted TEU Notes in a manner that would be materially adverse to the Lenders.

In addition, the Company will not exercise any right to require the early mandatory settlement of the Permitted TEU Purchase Contracts unless (other than pursuant to a Merger Termination Redemption): (i) no Default or Event of Default has occurred and is continuing prior to making such exercise or would arise after giving effect (including pro forma effect) thereto (including the resulting settlement of the Permitted TEU Purchase Contracts and the maximum required repurchase of the Permitted TEU Notes) and (ii) the aggregate amount of required repurchases of the Permitted TEU Notes during any fiscal year of the Company in connection with such exercise by the Company of its right to require the early mandatory settlement (when combined with the aggregate amount of Restricted Payments made during such fiscal year in reliance on Section 6.07(d)) shall not exceed (x) $25,000,000, if at the time of and immediately after giving effect thereto, the Leverage Ratio (recomputed on a pro forma basis as if such repurchases had occurred on the last day of the most recently ended fiscal quarter of the Company for which financial statements are available) is less than 3.00 to 1.00 but is greater than or equal to 2.50 to 1.00 or (y) $35,000,000, if at the time of and immediately after giving effect thereto, the Leverage Ratio (recomputed on a pro forma basis as if such repurchases had occurred on the last day of the most recently ended fiscal quarter of the Company for which financial statements are available) is less than 2.50 to 1.00 but is greater than or equal to 2.00 to 1.00; provided that, if at the time of and immediately after giving effect thereto, the Leverage Ratio (recomputed on a pro forma basis as if such repurchases had occurred on the last day of the most recently ended fiscal quarter of the Company for which financial statements are available) is less than 2.00 to 1.00, there shall be no dollar limitation on such repurchases.”

(l) The Event of Default set forth in Article VII(g) of the Credit Agreement is amended by adding the following proviso immediately following the semi-colon at the end of such Article VII(g):

“provided, further, that this clause (g) shall not apply to (i) any early payment requirement or unwinding or termination with respect to any Permitted TEU Capped Call Transaction, or satisfaction of any condition giving rise to or permitting the foregoing, in accordance with the terms thereof where neither the Borrowers nor any of their respective Affiliates are the “defaulting party” (or substantially equivalent term) under the terms of such Permitted TEU Capped Call Transaction or (ii) any right of the holders of Permitted TEU Notes to require the repurchase by the Company thereof as a result of a Merger Termination Redemption or an exercise by the Company of its right to require the early mandatory settlement of the Permitted TEU Purchase Contracts, which exercise satisfies the requirements of Section 6.12.”
