Section 8.2 Limitations on Liability.

(a) Liability Cap. Notwithstanding anything to the contrary in this Agreement or otherwise, the maximum aggregate amount that may be recovered by the Buyer Group or Seller Group under this Agreement (i) for representations and warranties set forth in Section 4.1, Section 4.2, Section 4.5, Section 4.7, Section 5.1, Section 5.2, Section 5.6 and Section 5.7 (the “Fundamental Representations”), shall not exceed the Purchase Price, and (ii) for all representations and warranties set forth in ARTICLE IV and ARTICLE V, excluding the Fundamental Representations, shall not exceed ten percent (10%) of the Purchase Price.

(b) Deductible. No Party shall be liable for, and no amounts of indemnity shall be payable in the case of, any claim for any inaccuracy in any representation or warranty (other than any Fundamental Representation) unless and until the Indemnified Parties have suffered, incurred or sustained otherwise indemnifiable Losses hereunder (after giving effect to any application of any deductions in accordance with Section 8.2(d)) in excess of an amount equal to one percent (1%) of the Purchase Price in

the aggregate (the “Deductible”), in which event the Indemnified Parties shall be entitled to claim indemnity for Losses only to the extent such Losses exceed the Deductible. Without limiting the generality of the foregoing, no Party shall be liable with respect to any individual claim for any inaccuracy in any representation or warranty (other than any Fundamental Representation) that results in otherwise indemnifiable Losses, and such Losses shall not be counted toward satisfaction of the Deductible, unless such Losses exceed an amount equal to fifteen/one hundredths of one percent (0.15%) of the Purchase Price.

(c) Failure to Notify. Neither Party shall have an obligation to indemnify the other Party with respect to a matter if such other Party fails to deliver written notification of a claim for indemnification under Section 8.3(a) for such matter before the expiration of the applicable survival period set forth in Section 8.4.

(d) Insurance Proceeds and Tax Benefits. Payments by either Party to the other Party with respect to which such Party has an indemnification obligation under this ARTICLE VIII, shall be limited to the amount of any liability or damage that remains after deducting therefrom an amount equal to any insurance proceeds or other similar payments received and any current cash Tax benefit realized as a result of such Losses by such Indemnified Party (as defined below) in the fiscal year in which such Losses were incurred. Each Party shall use its Commercially Reasonable Efforts to recover under insurance policies or similar agreements for any Losses prior to seeking indemnification under this Agreement. If the Indemnified Party receives insurance proceeds for Losses after an indemnification payment for such Losses has been made by the Indemnifying Party (as defined below) to the Indemnified Party, the Indemnified Party will refund the Indemnifying Party the amount of such insurance proceeds received by the Indemnified Party.

Section 8.3 Other Provisions Relating to Indemnification.

(a) Notices, etc. Each Person entitled to indemnification pursuant to this Agreement (the “Indemnified Party”) shall, upon obtaining knowledge of facts indicating that it may have a basis for a claim for indemnification hereunder, including receipt by it of notice of any demand, assertion, claim or proceeding by any Third Party (any such Third Party proceeding being referred to as a “Third Party Action”) with respect to any matter as to which it may be entitled to indemnity hereunder, give notice thereof in writing to the Person obligated hereunder to provide such indemnification (the “Indemnifying Party”) together with a reasonably detailed statement identifying the basis of and facts underlying such claim and a good faith estimate of the Indemnified Party’s Losses. For the avoidance of doubt, an Indemnifying Party shall have no obligation to provide indemnification pursuant to this ARTICLE VIII in the event the Indemnified Party’s written notification states only a general demand for indemnification which fails to identify a specific Loss or Third Party Action relating to such claim or demand.

(b) Right to Contest and Defend. The Indemnifying Party shall be given the opportunity, at its cost and expense, to contest and defend by all appropriate legal proceedings any Third Party Action with respect to which it is called upon to indemnify the Indemnified Party under the provisions of this Agreement; provided, however, that notice of the intention to contest and defend shall be delivered by the Indemnifying Party to the Indemnified Party within thirty (30) days following receipt of the notice provided for in Section 8.3(a) above. Any Third Party Action which the Indemnifying Party elects to contest and defend may be conducted in the name and on behalf of the Indemnifying Party or the Indemnified Party as may be appropriate. Such Third Party Action shall be conducted by counsel employed by the Indemnifying Party, but the Indemnified Party shall have the right to participate in such Third Party Action and to be represented by counsel of its own choosing at its

cost and expense; provided that, if the defendant(s) in any Third Party Action include both the Indemnifying Party and the Indemnified Party, and the Indemnified Party shall have reasonably concluded that (i) there may be legal defenses available to it that are inconsistent with those defenses available to the Indemnifying Party, or (ii) there is a conflict of interest that would prevent counsel for the Indemnifying Party from also representing the Indemnified Party (clauses (i) and (ii) collectively, “Differences or Conflicts”), then the Indemnified Party shall have the right to engage separate counsel at the cost and expense of the Indemnifying Party. If the Indemnified Party joins in any such Third Party Action, the Indemnifying Party shall have full authority, absent any Differences or Conflicts, to determine all action to be taken with respect thereto. At any time after the commencement of defense of any Third Party Action, the Indemnifying Party may request the Indemnified Party to agree in writing to the abandonment of such contest or to the payment, compromise or settlement by the Indemnifying Party of the asserted Third Party Action, which consent, absent any Differences or Conflicts, shall not be unreasonably withheld; provided, however, that the Indemnified Party shall not be required to consent to the abandonment of such contest or to the payment, compromise or settlement of such asserted Third Party Action if the result would be: (A) a finding or admission of any violation of Laws by the Indemnified Party (or any Affiliate thereof), (B) an adverse effect on any other Third Party Actions or claims of a similar nature that may be made against the Indemnified Party (or any Affiliate thereof), or (C) any remedy other than monetary damages which will be paid in full by the Indemnifying Party.

(c) Cooperation. If reasonably requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Action which the Indemnifying Party elects to contest or, if appropriate, in making any counterclaim against the Person asserting the Third Party Action, or any cross-complaint against any Person; provided that the Indemnifying Party shall reimburse the Indemnified Party for any reasonable expenses incurred by it in so cooperating at the request of the Indemnifying Party.

(d) Right to Participate. The Indemnified Party agrees, if reasonably requested by the Indemnifying Party, to afford the Indemnifying Party and its counsel the opportunity, at the Indemnifying Party’s expense, to be present at, and to participate in, conferences with all Persons asserting any Third Party Action against the Indemnified Party and conferences with representatives of or counsel for such Persons.

(e) Duty to Mitigate. The Parties shall have a duty to mitigate any Losses to which a right to indemnity applies hereunder, including all reasonable steps to mitigate such potential Losses upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise to any Losses.

(f) Exclusive Remedy. Except in the case of fraud, from and after the Closing Date, the indemnification provisions contained in this ARTICLE VIII shall constitute the sole remedy of the Parties for all claims arising from or relating to this Agreement or any of the instruments or transactions contemplated hereby (other than any remedies that are expressly set forth in any Operative Document), and each Party hereby releases the other Party from all other claims and causes of action, whether arising in Contract, in tort, or under any other legal theory arising from or relating to such circumstances. The Parties acknowledge and agree that the indemnification provisions contained in this ARTICLE VIII (including this Section 8.3(f)) have been specifically bargained for at arm’s length with the assistance of competent counsel and are reflected in the Purchase Price. For the avoidance of doubt, an Indemnifying Party shall have no obligation to provide indemnification pursuant to this ARTICLE VIII in the event the Indemnified Party’s written notification states only a general demand for

indemnification which fails to identify a specific Loss or Third Party Action relating to such claim or demand.

(g) No Duplication of Remedies. In no event shall either Party be entitled to duplicate compensation with respect to any claims or any breach of representation, warranty or agreement herein asserted under the terms of this Agreement, even though such claim or breach may be addressed by more than one provision of this Agreement.

(h) Severability of Indemnification Provisions. If any indemnity obligation set forth in this ARTICLE VIII or the application of any part thereof is held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction under applicable Laws, then, but only in such event, such indemnity obligation or part thereof shall be modified, read, construed and enforced to the maximum extent permitted by applicable Laws, and any remaining obligations or part thereof of such indemnity obligation that is valid and enforceable shall remain in full force and effect and be binding on the Parties.

(i) Tax Treatment of Indemnity Payment. Parties agree to treat any indemnity payment made pursuant to this ARTICLE VIII as an adjustment to the Purchase Price, for all Tax purposes, unless otherwise required by applicable Laws.

(a) Calculation. In calculating any Losses suffered or incurred by any Party as a result of a breach or inaccuracy of a representation or warranty by the other Party, no effect shall be given to any qualification or limitation as to “materiality” or similar qualifications or limitations.

Section 8.4 Survival of Provisions and Indemnification Obligations.

(a) The representations and warranties in this Agreement and the covenants and obligations set forth herein required to be performed prior to the Closing shall survive for six (6) months after the Closing Date; provided, that the Fundamental Representations shall survive indefinitely. For avoidance of doubt, the covenants and obligations set forth herein required to be performed from and after the Closing shall survive and be enforceable (subject to the limitations set forth in this ARTICLE VIII) after the Closing until fully performed; provided, that the indemnification obligations set forth in Section 8.1(a)(i) and Section 8.1(b)(i) shall survive the Closing until termination as provided in this Section 8.4.

(b) If an Indemnified Party shall have, before the expiration of the applicable survival period set forth in Section 8.4(a), previously made a claim by delivering a notice pursuant to Section 8.3(a) to the applicable Indemnifying Party, then any representation or warranty that would otherwise terminate in accordance with Section 8.4(a) above shall continue to survive until the related claim for indemnification has been satisfied or otherwise resolved in accordance with this Agreement.

ARTICLE IX.
GENERAL PROVISIONS

Section 9.1 Damages. Notwithstanding anything herein to the contrary, the Parties agree that the indemnification obligations of each Party hereto, and the recovery by any Party hereto or indemnitee of any Losses suffered by or incurred by it as a result of any breach or nonfulfillment by a Party hereto of any of its representations, warranties, covenants, agreements or other obligations under this Agreement, shall be limited to actual direct damages, and no Party shall be liable for consequential, incidental, exemplary, special, indirect or punitive damages arising under or in connection with this Agreement or otherwise as a result of, relating to or arising from the relationship between the

Parties hereunder, whether in Contract, tort (including negligence), strict liability or otherwise, or whether or not the Person at fault knew, or should have known, that such damage would be likely suffered (collectively, “Consequential Damages”).

Section 9.3 Specific Performance. Each Party acknowledges and agrees that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, the other Party would be damaged irreparably and monetary damages may not be a sufficient remedy.

Section 9.4 Waiver of Compliance. Any failure of Seller, on the one hand, or Buyer, on the other hand, to comply with any obligation, covenant, agreement or condition contained in this Agreement may be expressly waived in writing by the non-failing Party, but such waiver or failure to insist upon strict compliance shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Further, each of the Parties hereby irrevocably and unconditionally waives any objection or defense that it may have based on improper venue or forum non conveniens to the conduct of any such proceeding in any such courts. The Parties agree that either or both of them may file a copy of this paragraph with any court as written evidence of the knowing, voluntary and bargained agreement between the Parties to waive irrevocably any objections to jurisdiction, venue or to convenience of forum. Each of the Parties (on behalf of itself and its Affiliates) agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law or in equity.

(c) WITH RESPECT TO ANY ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY.

Any rule of Law or any legal decision that would require interpretation of any claimed ambiguities in this Agreement against the Party that drafted it shall have no application and is expressly waived.

Section 9.13 Severability. Whenever possible, each provision or part thereof of this Agreement shall be interpreted in such manner as to be valid and effective under applicable Laws, but if any provision or part thereof of this Agreement or the application of any such provision or part thereof to any Person or circumstance shall be held invalid, illegal, or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality, or unenforceability shall not affect any other provision or part thereof.
