The Indemnifying Party shall have thirty (30) days (or such lesser number of days set forth in the Claim Notice as may be required by court proceedings in the event of a litigated matter) after receipt of the Claim Notice (the “ Notice Period ”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third Party Claim provided that the Indemnifying Party may only elect to defend the Indemnified Party and assume direction and control of such defense if (i) the Third Party Claim does not seek an order, injunction or other equitable relief that if granted would be material to the Indemnified Party, (ii) the Indemnified Party shall not have reasonably concluded, based on the advice of outside counsel, that representation of both the Indemnified Party and the Indemnifying Party would be inappropriate due to actual or potential differing interests between them and (iii) the Indemnifying Party actively and diligently defends in good faith such Third Party Claim and keeps the Indemnified Party reasonably informed of the progress of such Third Party Claim; provided , further , that, from the date of such notice electing to assume the conduct and control of the defense of a Third Party Claim, the Indemnifying Party, regardless of whether it is otherwise required to indemnify the Indemnified Party hereunder with respect to such Third Party Claim, shall be responsible for the costs and fees of such Indemnified Party’s attorneys and related litigation expenses incurred by it in connection with such Third Party Claim.

(b) In the event that the Indemnifying Party validly notifies the Indemnified Party within the Notice Period that it shall assume the defense of the Indemnified Party against a Third Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense at its expense; provided , that once the Indemnifying Party has duly assumed the defense of a Third Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing. The Indemnified Party shall participate in any such defense at its expense unless (i) the Indemnified Party shall have reasonably concluded, based on the advice of outside counsel, that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (ii) the Indemnifying Party shall have authorized the Indemnified Party to employ separate counsel at the Indemnifying Party’s expense. The Indemnifying Party shall not, except with the consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed), settle, compromise or discharge, or admit any liability with respect to, any such Third Party Claim unless the relief consists solely of money Losses to be paid by the Indemnifying Party and includes as an unconditional term thereof the giving by the Person(s) asserting such claim to all Indemnified Parties of an unconditional release from all liability with respect to such claim.

Table of Contents

(c) If the Indemnifying Party elects not to defend the Indemnified Party against a Third Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise, the Indemnified Party shall have the right but not the obligation to assume its own defense; it being understood that the Indemnified Party’s right to indemnification for a Third Party Claim shall not be adversely affected by assuming the defense of such Third Party Claim. The Indemnified Party shall not settle a Third Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed.

(d) The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and adequate defense of a Third Party Claim, including by providing access to each other’s relevant business records and other documents, and employees.

In any event, the Indemnifying Party shall pay to the Indemnified Party, by wire transfer of immediately available funds, the amount of any Loss for which it is liable hereunder no later than thirty (30) days following any final determination of such Loss and the Indemnifying Party’s liability therefor. A “final determination” shall exist when (i) the parties to the dispute have reached an agreement in writing, (ii) a court of competent jurisdiction shall have entered a final and non-appealable order or judgment, or (iii) an arbitration or like panel shall have rendered a final non-appealable determination with respect to disputes the parties have agreed to submit thereto.

In the event that an Indemnified Party has any rights against a third party with respect to any occurrence, claim or loss that results in a payment by an Indemnifying Party under this Article VII, such Indemnifying Party shall be subrogated to such rights to the extent of such payment; provided that until the Indemnified Party recovers full payment of the Loss, any and all claims of the Indemnifying Party against any such third party on account of said indemnity payment is hereby expressly made subordinate and subject in right of payment to the Indemnified Party’s rights against such third party. Without limiting the generality or effect of any other provision hereof, each Indemnified Party and Indemnifying Party shall duly execute upon request all instruments reasonably necessary to evidence and perfect the subrogation and subordination rights detailed herein, and otherwise cooperate in the prosecution of such claims.

(b) Purchase Price Adjustment .

(c) Taxes . In calculating the amount of any Loss, there shall be deducted an amount equal to any Tax benefit (including the utilization of a Tax loss or Tax credit carried forward) actually realized by the Indemnified Party and calculated by determining the difference in the Tax liability of the Indemnified Party “with and without” such Loss.

(d) Reimbursement . If an Indemnified Party recovers an amount from a third party in respect of a Loss that is the subject of indemnification hereunder after all or a portion of such Loss has been paid by an Indemnifying Party pursuant to this Article VII, the Indemnified Party shall promptly remit to the Indemnifying Party the amount, if any, by which (i) the sum of (A) the amount paid by the Indemnifying Party to such Indemnified Party in respect of such Loss plus (B) the amount received from the third party in respect thereof, exceeds (ii) the full amount of the Loss.

Calculation of Interest and Fees:	Other than calculations in respect of interest at the Alternate Base Rate (which shall be made on the basis of actual number of days elapsed in a 365/366 day year), all calculations of interest and fees shall be made on the basis of actual number of days elapsed in a 360-day year.

Cost and Yield Protection:	Customary for transactions and facilities of this type, including, without limitation, in respect of breakage or redeployment costs incurred in connection with prepayments, changes in capital adequacy and capital requirements or their interpretation, illegality, unavailability, reserves without proration or offset and payments free and clear of withholding or other taxes.

In addition, a fronting fee at a rate per annum and payable as established by separate agreement between the Borrower and the Issuing Bank will be payable to the Issuing Bank for its own account.

Optional Prepayments and Commitment Reductions:	The Senior Credit Facilities may be prepaid at any time in whole or in part without premium or penalty, except that any prepayment of LIBOR advances other than at the end of the applicable interest periods therefor shall be made with reimbursement for any funding losses and redeployment costs of the Lenders resulting therefrom (excluding loss of profits). Each such prepayment of the Term Loan Facilities shall be applied (i) between the Term Loan Facilities as directed by the Borrower and (ii) to the principal repayment installments of each of the Term Loan Facilities as directed by the Borrower.
