NOTICE AND DEFENSE OF THIRD PARTY CLAIMS. The obligations of a party from whom indemnification is sought (the "Indemnitor") to indemnify the party seeking indemnification (the "Indemnitee") under this Article 6 with respect to Damages resulting from the assertion of liability by a third party (a "Third Party Claim"), will be subject to the following terms and conditions: (a) Any party against whom any Third Party Claim is asserted shall notify the Indemnitor by registered mail at the address provided in Section 7.3 of any such Third Party Claim promptly after learning of such Third Party Claim, and the Indemnitor may at its option undertake the defense thereof by representatives of its own choosing, who shall be reasonably satisfactory to the Indemnitee, PROVIDED, HOWEVER, that the Indemnitee's failure to so notify Indemnitor shall not constitute a Breach of this Agreement or any of the other Transactional Agreements; PROVIDED, FURTHER, that the Indemnitor shall not indemnify the Indemnitee (i) for any additional expenses, costs or Damages resulting from the Indemnitee's untimely notice or failure to provide notice pursuant to this Section 6.7 or (ii) any Damages whatsoever to the extent that the Indemnitee's untimely notice or failure to provide notice pursuant to this Section 6.7 materially prejudices the Indemnitor. If an Indemnitor, within thirty (30) days after notice of any such Third Party Claim, or such shorter period as is reasonably required, fails to assume the defense of such Third Party Claim, or does not continue to defend such Third Party Claim in good faith, the Indemnitee against whom such claim has been made shall (upon further notice to the Indemnitor) have the right to undertake jointly with the 22 Indemnitor the defense, compromise or settlement of such Third Party Claim on behalf of and for the account and risk, and at the expense, of the Indemnitor, by representatives selected by the Indemnitee who shall be reasonably satisfactory to the Indemnitor. If an Indemnitor elects to assume the joint defense of such Third Party Claim, the Indemnitee shall have the right to employ (at its expense) its own counsel and to participate in such defense. If an Indemnitee reasonably believes that the handling of the defense by the Indemnitor of the Third Party Claim itself would result in a material adverse effect on any Indemnitee or its Affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Article 6, then the Indemnitee may, at its option and expense and through counsel of its choice, jointly with the Indemnitor assume joint control of the defense of such Third Party Claim, provided that nothing in this sentence shall be deemed to relieve the Indemnitor of any liability it may have under this Article 6 other than liability for the expenses of Indemnitee's counsel. (b) Notwithstanding anything in this Section 6.7 to the contrary, the Indemnitor shall not enter into any settlement or compromise of any action, suit or proceeding or consent to the entry of any judgment (i) which does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnitee of a written release from all liability in respect of such action, suit or proceeding or (ii) for other than monetary damages to be borne in full by the Indemnitor, without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld. Whether or not the Indemnitor shall have assumed the defense of a Third Party Claim, the Indemnitee shall not admit any liability with respect to, or settle, compromise or discharge, such Third Party Claim without the Indemnitor's prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed if and to the extent the Indemnitor has not assumed or failed to timely assume the defense of a Third Party Claim. (c) The parties hereto shall use commercially reasonable efforts to minimize Damages from Third Party Claims and shall act in good faith in responding to, defending against, settling or otherwise dealing with such claims, including cooperating in any defense and giving each other reasonable access to information relating thereto. 6.8. LOSSES NET OF INSURANCE, RECOVERIES, ETC. The amount of any Damages for which indemnification is provided under this Article 6 shall be (i) reduced by (A) any portion of such Damages previously indemnified, (B) any Damages previously indemnified under Article 6 to another Indemnitee with respect to the same facts and circumstances given rise to such indemnification obligation and (C) any amounts actually recovered by the Indemnitee under insurance policies in effect and applicable to such Damages or from any third party with respect to such Damages. 23 6.9. SOLE AND EXCLUSIVE REMEDIES. This Article 6 constitutes the sole and exclusive remedy of the parties hereto for any and all Damages under or in connection with this Agreement. No party to this Agreement may avoid such limitation on liability by seeking damages for breach of contract, tort or pursuant to any other theory of liability. No claim shall be brought or maintained by any party hereto or its Affiliates, successors or permitted assigns against any other party hereto, and no recourse shall be brought or granted against any of them, by virtue of or based upon any alleged misrepresentation or inaccuracy in or breach of any of the representations, warranties or covenants of any party set forth or contained in this Agreement, any information, document or material furnished or made available to Purchaser by the Seller or any of their respective authorized representatives in certain "data rooms," management presentations or in any other form in connection with the transactions contemplated by this Agreement, except and solely as set forth in this Article 6. Notwithstanding the foregoing, this exclusive remedy for damages does not preclude a party from bringing an action for fraud or for specific performance or injunctive relief. IN NO EVENT WILL PURCHASER OR SELLER BE LIABLE FOR ANY CONSEQUENTIAL, INDIRECT, EXEMPLARY, SPECIAL, OR INCIDENTAL DAMAGES ARISING FROM OR RELATING TO THIS AGREEMENT. 7. MISCELLANEOUS 7.1. FURTHER ASSURANCES. Each party hereto shall execute and/or cause to be delivered to each other party hereto such instruments and other documents, and shall take such other actions, as such other party may reasonably request (prior to, at or after the Closing) for the purpose of carrying out or evidencing any of the Transactions. 7.2. FEES AND EXPENSES. (a) Except for those expenses specifically set forth in Section 7.2(b), Purchaser shall bear and pay all fees, costs and expenses that have been incurred or that are in the future incurred by any party hereto in connection with (i) the negotiation, preparation and review of any letter of intent, term sheet or similar document relating to any of the Transactions; (ii) the furnishing of information to the Purchaser and its Representatives in connection with its investigation and review of each of the Acquired Companies or the Intellectual Property Rights; (iii) the negotiation, preparation and review of this Agreement (including the Disclosure Schedule), the other Transactional Agreements and all certificates, opinions and other instruments and documents delivered or to be delivered in connection with the Transactions (other than the legal fees and expenses payable to counsel for Seller); (iv) the preparation and submission of any filing or notice required to be made or given in connection with any of the Transactions, and the obtaining of any Consent required to be obtained by the Purchaser in connection with any of the Transactions; (v) the consummation and performance of the Transactions; and (vi) the registration of the Purchase Shares with the SEC and maintenance of the effectiveness of Acacia's resale registration statement on which such shares shall be registered (as set forth in the Registration Rights Agreement).
