3.6Securities Law.

(a)Seller acknowledges that the offer and sale of the Stock Consideration is intended to be exempt from registration under the Securities Act and all applicable state securities Law.

(i)The Seller will indemnify and hold harmless the Buyer Indemnitees from, and pay and reimburse each Buyer Indemnitee for, all Losses directly or indirectly relating to or arising from: (i) any breach or inaccuracy, or any allegation of any third party that, if true, would be a breach or inaccuracy, of any representation or warranty made by the Seller in Article III; (ii) any breach of any covenant or agreement, or any representation or warranty, of the Seller in this Agreement; or (iii) any misrepresentations by or fraudulent conduct of the Seller.

8.6Third-Party Claims.

(a)If a third party commences or threatens a Proceeding (a “Third-Party Claim”) against any Person (the “Indemnified Party”) with respect to any matter that the Indemnified Party might make a claim for indemnification against any Party (the “Indemnifying Party”) under this Article VIII, then the Indemnified Party must notify the Indemnifying Party (or the Seller, in the case of the Seller) thereof in writing of the existence of such Third-Party Claim and must deliver copies of any documents served on the Indemnified Party with respect to the Third-Party Claim; provided, however, that any failure to notify the Indemnifying Party or deliver copies will not relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is materially prejudiced by such failure.

(b)Upon receipt of the notice described in Section 8.6(a), the Indemnifying Party will have the right to defend the Indemnified Party against the Third-Party Claim with counsel reasonably satisfactory to the Indemnified Party so long as (i) within ten days after receipt of such notice, the Indemnifying Party notifies the Indemnified Party in writing that the Indemnifying Party will, subject to the limitations of Section 8.4, indemnify the Indemnified Party from and against any Losses the Indemnified Party may incur relating to or arising out of the Third-Party Claim, (ii) the Indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the Third-Party Claim and fulfill its indemnification obligations hereunder, (iii) the Indemnifying Party is not a party to the Proceeding or the Indemnified Party has determined in good faith that there would be no conflict of interest or other inappropriate matter associated with joint representation, (iv) the Third-Party Claim does not involve, and is not likely to involve, any claim by any Governmental Body, (v) the Third-Party Claim involves only money damages and does not seek an injunction or other equitable relief, (vi) settlement of, or an adverse judgment with respect to, the Third-Party Claim is not, in the good faith judgment of the Indemnified Party, likely to establish a precedential custom or practice adverse to the continuing business interests of the Indemnified Party, (vii) the Indemnifying Party conducts the defense of the Third-Party Claim actively and diligently and

(viii) the Indemnifying Party keeps the Indemnified Party apprised of all developments, including settlement offers, with respect to the Third-Party Claim and permits the Indemnified Party to participate in the defense of the Third-Party Claim.

(c)So long as the Indemnifying Party is conducting the defense of the Third-Party Claim in accordance with Section 8.6(b), (i) the Indemnifying Party will not be responsible for any attorneys’ fees incurred by the Indemnified Party regarding the Third-Party Claim (other than attorneys’ fees incurred prior to the Indemnifying Party’s assumption of the defense pursuant to Section 8.6(b)) and (ii) neither the Indemnified Party nor the Indemnifying Party will consent to the entry of any judgment or enter into any settlement with respect to the Third-Party Claim without the prior written consent of the other party, which consent will not be withheld unreasonably. If the Indemnified Party desires to consent to the entry of judgment with respect to or settle a Third-Party Claim but the Indemnifying Party refuses, then the Indemnifying Party will be responsible for all Losses with respect to such Third-Party Claim, without giving effect to the Basket or the Cap.

(d)If any condition in Section 8.6(b) is or becomes unsatisfied, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third-Party Claim in any manner it may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), (ii) the Indemnifying Party will reimburse the Indemnified Party promptly and periodically (but no less often than monthly) for the costs of defending against the Third-Party Claim, including attorneys’ fees and expenses, and (iii) the Indemnifying Party will remain responsible for any Losses the Indemnified Party may incur relating to or arising out of the Third-Party Claim to the fullest extent provided in this Article VIII.

8.7Other Indemnification Matters. Any claim for indemnification under this Article VIII must be asserted by providing written notice to the Seller (or the Buyer, in the case of a claim by the Seller) specifying the factual basis of the claim in reasonable detail to the extent then known by the Person asserting the claim. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or agreement, will not affect the right to indemnification, payment of damages, or other remedy based on any such representation, warranty, covenant or agreement.

8.8Exclusive Remedy. After the Closing, this Article VIII will provide the exclusive legal remedy for all suits, actions, claims and proceedings arising out of or based upon this Agreement, the other transaction documents, or the transactions contemplated hereby or thereby except for claims based upon fraud.

10.13Specific Performance. Each Party acknowledges that the other Parties would be damaged irreparably and would have no adequate remedy of law if any provision of this Agreement is not performed in accordance with its specific terms or otherwise is breached. Accordingly, each Party agrees that the other Parties will be entitled to an injunction to prevent any breach of any provision of this Agreement and to enforce specifically any provision of this Agreement, in addition to any other remedy to which they may be entitled and without having to prove the inadequacy of any other remedy they may have at law or in equity and without being required to post bond or other security.
