The covenants of the Parties in this Agreement shall survive the Closing without limitation (except pursuant to their terms).

Section 7.2 Indemnification.

(a) Subject to a Party (an “Indemnified Party”) making a written claim for indemnification against the other Party (the “Indemnifying Party”) pursuant to Section 7.3 within the survival period set forth in Section 7.1, the Indemnifying Party shall indemnify and hold the Indemnified Party harmless from and against any and all Losses the Indemnified Party may suffer (including Losses suffered or paid, directly or indirectly, through the application of the Indemnified Party’s assets or otherwise), arising out of, in the nature of, incident or relating to, resulting from, or caused by (i) the failure of any representation or warranty set forth in ARTICLE III or ARTICLE IV made by the Indemnifying Party to be true and correct in all material respects at and as of the Closing Date or (ii) the breach in any material respect by the Indemnifying Party of any of its covenants under this Agreement.

(b) No indemnification by either Party pursuant to Section 7.2(a) shall be due and payable unless the aggregate amount of all such claims asserted by the Indemnified Party against the Indemnifying Party exceeds US$3,000,000.00 (the “Basket Amount”), whereupon the applicable Indemnifying Party shall be obligated to pay only the excess of the aggregate amount of such claims for indemnification over the Basket Amount.

(c) A Party’s maximum aggregate indemnification obligations pursuant to Section 7.2(a) are limited to US$40,000,000.00; provided, however, that the maximum aggregate indemnification obligations pursuant to Section 7.2(a) are limited to $224,000,000 to the extent arising out of, in the nature of, incident or relating to, resulting from, or caused by the failure of any representation or warranty set forth in Section 3.1(l) through Section 3.1(p), or Section 4.6 to be true and correct at and as of the Closing Date.

(d) Each Party hereby acknowledges and agrees that its sole and exclusive monetary remedy with respect to this Agreement, regardless of whether the relief demanded or sought is found in contract or tort, shall be pursuant to the indemnification provisions set forth in this ARTICLE VII. Notwithstanding anything in the immediately preceding sentence to the contrary, nothing in this Section 7.2(d) shall limit in any way the availability of specific performance, injunctive relief, rescission, or other

non-monetary remedies to which a Party may otherwise be entitled. In no event shall either Party be liable to any other Person for such other Person’s (i) lost profits, loss of use, or lost revenues, (ii) punitive, multiple, or other exemplary damages, or (iii) any other indirect, incidental, special, or consequential Losses. Each Party waives and relinquishes claims for such lost profits, loss of use, lost revenues, or other indirect, incidental, special, or consequential Losses.

Section 7.3 Procedures.

(a) In order for an Indemnified Party under this ARTICLE VII to be entitled to any indemnification provided for under this Agreement, such Indemnified Party shall, promptly following the discovery of the matters giving rise to any Loss, notify the Indemnifying Party under this ARTICLE VII in writing of its claim for indemnification for such Loss, specifying in reasonable detail the nature of such Loss and the amount of the liability estimated to accrue therefrom; provided, however, that the Indemnified Party’s failure to so notify the Indemnifying Party shall not release the Indemnifying Party, in whole or in part, from its obligations under this ARTICLE VII, except to the extent (and solely to the extent) that the Indemnifying Party will have been actually prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five Business Days after the Indemnified Party’s receipt of such request, all information and documentation reasonably requested by the Indemnifying Party with respect to such Loss.

(b) If any third party notifies any Indemnified Party seeking indemnification under Section 7.2, with respect to any matter, claim, investigation, action, suit, charge, complaint, demand, or other Legal Proceeding, whether pending or threatened (an “Action”), that may give rise to a claim for indemnification under this ARTICLE VII, then the Indemnified Party shall promptly give notice of the Action to the Indemnifying Party pursuant to Section 8.5; provided, however, that the Indemnified Party’s failure to so notify the Indemnifying Party of any Action shall not release the Indemnifying Party, in whole or in part, from its obligations under this ARTICLE VII, except to the extent (and solely to the extent) that the Indemnified Party’s failure to so notify actually prejudices the Indemnifying Party’s ability to defend against such Action.

(c) The Indemnified Party may, at the sole expense and liability of the Indemnifying Party, exercise full control of the defense, compromise, or settlement of any such Action, unless, at any time within 30 days after the Indemnified Party has given notice to the Indemnifying Party of the Action, the Indemnifying Party (i) delivers a written confirmation to such Indemnified Party that the indemnification provisions of Section 7.2 are applicable to such Action and that, subject to the other provisions of this ARTICLE VII, the Indemnifying Party shall indemnify such Indemnified Party in respect of such Action pursuant to the terms of Section 7.2, (ii) notifies such Indemnified Party in writing of the Indemnifying Party’s intention to assume the defense thereof and thereafter conducts the defense actively and diligently, and (iii) retains legal counsel reasonably satisfactory to such Indemnified Party to conduct the defense of such Action. Notwithstanding anything to the contrary in the immediately preceding sentence, the

Indemnifying Party shall not have any right to assume the defense of such Action, if (1) such Action seeks an injunction or other equitable relief and not money damages only, or (2) the settlement or compromise of, or an adverse judgment with respect to, such Action is, in the good faith judgment of the Indemnified Party, likely to establish a precedent, custom or practice materially adverse to the continuing business interests or the reputation of the Indemnified Party.

(d) The Indemnified Party and the Indemnifying Party shall use their commercially reasonable efforts to cooperate with the Party assuming the defense, compromise, or settlement of any such Action in accordance herewith in any manner that such Party reasonably may request. If the Indemnifying Party assumes the defense of any such Action, the Indemnified Party shall have the right to employ separate counsel and to participate in (but not control) the defense, compromise, or settlement thereof, but the fees and expenses of such counsel shall be the expense of such Indemnified Party unless (i) the Indemnifying Party has specifically agreed to pay such fees and expenses or (ii) the Indemnified Party has been advised by its counsel that there may be one or more legal defenses from claims available to it that are different from or additional to those available to the Indemnifying Party or that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in the conduct of the defense of such Action (in either of which cases the Indemnifying Party shall not have the right to direct the defense, compromise, or settlement of such Action on behalf of the Indemnified Party), and in any such case the reasonable fees and expenses of such separate counsel shall be borne by the Indemnifying Party, it being understood and agreed, however, that the Indemnifying Party shall not be liable for the fees and expenses of more than one separate firm of attorneys at any time for the Indemnified Party. No Indemnified Party shall settle or compromise or consent to entry of any judgment with respect to any such Action for which it is entitled to indemnification hereunder without the prior written consent of the Indemnifying Party, unless the Indemnifying Party fails to assume control of such Action in the manner provided in Section 7.3(c). The Indemnifying Party shall not, without the written consent of the Indemnified Party, settle or compromise or consent to entry of any judgment with respect to any such Action (1) in which any relief other than the payment of money damages is or may be sought against any Indemnified Party, or (2) that does not include as an unconditional term thereof the giving by the claimant, party conducting such investigation, plaintiff or petitioner to such Indemnified Party of a release from all liability with respect to such Action.

Section 7.4 Insurance Proceeds. Notwithstanding anything to the contrary in the other provisions of this ARTICLE VII, the amount that any Indemnifying Party may be required to pay to an Indemnified Party pursuant to this ARTICLE VII shall be reduced (retroactively, if necessary) by any insurance proceeds or refunds actually recovered by or on behalf of the applicable Indemnified Party in reduction of the related Losses (on an after-Tax basis). If an Indemnified Party receives the payment required by this ARTICLE VII from the Indemnifying Party in respect of Losses and subsequently receives insurance proceeds in respect of such Losses, then the Indemnified Party shall promptly repay to the Indemnifying Party a sum equal to the amount of such insurance proceeds or refunds actually received, net of costs and expenses and on an after-Tax basis, but not exceeding the amount paid by the Indemnifying Party to such

Indemnified Party in respect of such Losses. No representation, warranty, covenant, or agreement contained in this Agreement is for the benefit of any insurer.
