Capitalized terms used but not defined herein shall have the meaning ascribed to them in the Merger Agreement.

              1.      GUARANTEE.      To induce the Guaranteed Party to enter into the Merger Agreement, the Guarantor, intending to be legally bound, hereby absolutely, irrevocably and unconditionally, guarantees to the Guaranteed Party, but only up to the Cap (as defined below), the due and punctual observance, performance and/or discharge of payment when due or required of (i) the Parent Termination Fee pursuant to Section 8.3(c) of the Merger Agreement, (ii) the Guarantor’s obligation to pay damages subject to the Parent Liability Cap in Section 8.3(f) of the Merger Ag reement, or (iii) Guarantor’s and Merger Sub’s obligations pursuant to Section 9.5 of the Merger Agreement to perform specifically the terms and provisions of the Merger Agreement, in each case, solely to the extent such Parent Termination Fee, damages or specific performance, as the case may be, are found in a final judicial determination (or a settlement tantamount thereto), to be due and payable or to be required, as applicable, pursuant to the terms and conditions of the Merger Agreement (as so found, the “Obligations”); provided that in no event shall the Guarantor’s aggregate liability under this Limited Guarantee exceed $570,800,000 (the “Cap”), it being understood that in no event shall this Limited Guarantee be enforced without giving effect to the Cap. All payments hereunder shall be made in lawful money of the Un ited States, in immediately available funds. Subject to the Cap, the Guarantor promises and undertakes to make all payments hereunder free and clear of any deduction, offset, defense, claim or counterclaim of any kind (other than defenses to the payment of the Obligations that are available to the Guarantor or Merger Sub under the Merger Agreement).

              Upon tender of the Parent Termination Fee pursuant to Section 8.3(c) of the Merger Agreement no member of the Parent Group shall have any further liability or obligation relating to or arising out of this Limited Guarantee, the Merger Agreement, the equity commitment letter dated the date hereof among the Funds, the Guarantor and the Guaranteed Party (the “Equity Commitment Letter”) or otherwise. In the event of breach by either the Guarantor or Merger Sub of its representations and warranties or covenants under the Merger Agreement, the Guaranteed Party shall be entitled to seek damages (which the parties acknowledge and agree shall not be limited to reimbursement of expenses or out-of-pocket costs , and may include, subject to the Cap and to the extent proven, the benefit of the bargain lost by a party or a party’s shareholders (taking into consideration all relevant matters, including other combination

              If the Guarantor or Merger Sub is in breach of its Obligations, then the Guaranteed Party may at any time and from time to time, at the Guaranteed Party’s option, and so long as the Guarantor or Merger Sub remains in breach of its Obligations, take any and all actions available hereunder or under applicable Law to collect on the Guarantor’s liabilities hereunder in respect of such Obligations subject to the Cap; provided, that the Guaranteed Party acknowledges that the Guarantor’s liability hereunder and under the Merger Agreement is subject to the Cap.

              Subject to and in furtherance of the foregoing, the Guarantor acknowledges that the Guaranteed Party may, in its sole discretion, bring and prosecute a separate action or actions against the Guarantor for the full amount of the Obligations (subject to the Cap).
