Section 11.01.  Survival.  Except for the representations and warranties of ACI contained in Article 3 made with respect to the Transferred Subsidiaries, which shall survive the Closing until the second anniversary of the Closing Date, the representations and warranties of the parties hereto contained in this Agreement shall survive the Closing until the first anniversary of the Closing Date; provided that Sections 3.01, 3.02, 3.04(i), 3.06, 3.07, 3.12(a), 3.12(b) and 3.21 shall survive indefinitely and Section 3.17 and 8.02 shall survive until the thirtieth day after the expiration of the applicable statute of limitations (taking into account any tolling periods and other extensions).  The covenants set forth in this Agreement shall survive the Closing indefinitely or for the shorter period explicitly specified therein, and any breaches thereof shall survive indefinitely.  Notwithstanding the preceding sentence, any breach of representation, warranty, covenant or agreement in respect of which indemnity may be sought under this Agreement shall survive the time at which it would otherwise terminate pursuant to the preceding sentence, if notice of the breach giving rise to such right of indemnity shall have been given to the party against whom such indemnity may be sought prior to such time.

Section 11.02.  Indemnification.  (a) ACI hereby indemnifies Buyer and its Affiliates against and agrees to hold each of them harmless from any and all liability, damage, loss and expense (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses in connection with any action, suit or proceeding whether involving a third party claim or a claim solely between the parties hereto) (“Damages”) actually incurred or suffered by Buyer or any of its Affiliates arising out of:

(i)            any breach of, or inaccuracy in, any representation or warranty (each such breach of, or inaccuracy in, any representation or warranty a “Warranty Breach”) made by any of the Sellers in this Agreement or in any Schedules or certificates delivered pursuant hereto (determined as if all qualifications as to materiality, including each reference to the defined term “Material Adverse Effect,” were deleted from the applicable representation or warranty);

(ii)           any breach or violation of any covenant or agreement of any of the Sellers made or to be performed pursuant to this Agreement;

(iii)          any Excluded Liability;

54

(iv)          any Liability of any Transferred Subsidiary resulting from, arising out of or related to any of the matters required to be set forth on Schedule 3.11 or any other Liability of any Transferred Subsidiary arising as a result of any legal or equitable action or judicial or administrative proceeding initiated at any time in respect of any action by or inaction of any Seller or Transferred Subsidiary or any of their respective directors, officers, employees or agents on or prior to the Closing Date.

provided that with respect to indemnification by ACI for Warranty Breaches pursuant to Section 11.02(a)(i), (A) the amount of Damages incurred or suffered arising out of any Warranty Breach shall be determined as if all qualifications as to materiality, including each reference to the defined term “Material Adverse Effect,” were deleted from the applicable representation or warranty; (B) no individual Warranty Breach shall be deemed to have occurred unless the amount of Damages with respect thereto exceeds $25,000; (C) ACI shall not be liable unless the aggregate amount of Damages with respect to all such Warranty Breaches exceeds $925,000, and then only to the extent of the excess over $925,000 and (D) ACI’s maximum liability for all such Warranty Breaches shall not exceed $18,500,000; and provided further that the limitations set forth in clauses (C) and (D) shall not apply to Warranty Breaches in respect of Sections 3.01, 3.02, 3.04(i), 3.06, 3.07, 3.12(a), 3.12(b), 3.17, 3.21 or 8.02.

(b)           Buyer hereby indemnifies ACI and its Affiliates against and agrees to hold each of them harmless from any and all Damages actually incurred or suffered by ACI or any of its Affiliates arising out of:

(i)            any Warranty Breach or breach of covenant or agreement made or to be performed by Buyer pursuant to this Agreement; or

(ii)           any Assumed Liability.

Section 11.03.  Procedures.  (a) The party seeking indemnification under Section 11.02 (the “Indemnified Party”) agrees to give prompt notice to the party against whom indemnity is sought (the “Indemnifying Party”) of the assertion of any claim, or the commencement of any suit, action or proceeding in respect of which indemnity may be sought under such Section and will provide the Indemnifying Party such information with respect thereto that the Indemnifying may reasonably request.  The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have adversely prejudiced the Indemnifying Party.

(b)           The Indemnifying Party shall be entitled to participate in the defense of any Claim asserted by any third party (“Third Party Claim”).  In addition, the Indemnifying Party will have the right to defend, at its own expense, the Indemnified Party against the Third Party Claim with counsel of its choice so long as (i) the Indemnifying Party provides the Indemnified Party with evidence reasonably acceptable to the Indemnified Party that the Indemnifying Party will

55

have adequate financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder, (ii) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Party, and (iii) the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently.

(c)           If the Indemnifying Party shall assume the control of the defense of any Third Party Claim in accordance with the provisions of this Section 11.03, (i) the Indemnifying Party shall obtain the prior written consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement of such Third Party Claim if the settlement does not release the Indemnified Party from all liabilities and obligations with respect to such Third Party Claim or the settlement imposes injunctive or other equitable relief against the Indemnified Party and (ii) the Indemnified Party shall be entitled to participate in the defense of such Third Party Claim and to employ separate counsel of its choice for such purpose.  The fees and expenses of such separate counsel shall be paid by the Indemnified Party.

(d)           Each party shall cooperate, and cause their respective Affiliates to cooperate, in the defense or prosecution of any Third Party Claim and shall promptly furnish or cause to be furnished such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials or appeals, as may be reasonably requested in connection therewith.

Section 11.04.  Supplemental Schedules.  From time to time, but no later than ten days prior to the Closing Date, Sellers may disclose any matters arising or occurring after the date hereof that, if they had arisen or occurred on or prior to the date hereof, would have been required to be disclosed on the Schedules.  Buyer shall have the right to review such disclosure for a period of five days after receipt thereof.  At any time within such five day time period, Buyer shall have the right to terminate this Agreement by delivery of a notice to Seller if, in the absence of an amendment to the Schedules to incorporate such disclosure and taking into account the effect of any items previously disclosed by Sellers pursuant to this Section 11.04, the condition to Buyer’s obligation set forth in Section 10.02(a) would not be able to be satisfied.  This notice, if given, shall specify the information forming the basis for the decision to terminate.  Sellers shall have five days after receipt of such notice to review with Buyer the information forming the basis of the decision to terminate and to attempt to agree on corrective measures, if any.  If the parties cannot agree on corrective measures within such five day period, then this Agreement shall terminate.  If this Agreement is not terminated as permitted by this Section, the Schedules shall be deemed to have been amended by such disclosures as of the end of the time immediately prior to the Closing, and Sellers shall have no liability hereunder for any such disclosures.

Section 11.05.  Calculation of Damages.  (a) The amount of any Damages payable under Section 11.02 by the Indemnifying Party shall be net of any

56

amounts recovered or recoverable by the Indemnified Party under applicable insurance policies, or from any other Person alleged to be responsible therefor, and the Indemnified Party shall use commercially reasonable efforts to recover such amounts.  If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for any Damages, subsequent to an indemnification payment by the Indemnifying Party, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party, net of any expenses incurred by such Indemnified Party in collecting such amount (including any increased premiums under any such insurance policies).  For purposes of calculating the unpaid Taxes of the Transferred Subsidiaries and HEE as of the Closing Date for which ACI is responsible pursuant to Section 8.02(d)(viii), in the case of any Taxes that are payable for a taxable period that includes (but does not end on) the Closing Date, the portion of such Tax related to the portion of such taxable period ending on the Closing Date shall, in the case of any Tax based upon or related to income, be deemed equal to the amount which would be payable if the relevant taxable period ended on the Closing Date.

(b)           The Indemnifying Party shall not be liable under Section 11.02 for any punitive or speculative Damages.

Section 11.06.  Assignment of Claims.  If the Indemnified Party receives any payment from an Indemnifying Party in respect of any Damages pursuant to Section 11.02 and the Indemnified Party could have recovered all or a part of such Damages from a third party (a “Potential Contributor”) based on the underlying Claim asserted against the Indemnifying Party, the Indemnified Party shall assign such of its rights to proceed against the Potential Contributor as are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment.

Section 11.07.  Exclusivity.  Except with respect to claims based upon fraud or intentional misrepresentation, the indemnification rights provided in this Article 11 shall be the sole and exclusive remedy of the parties following the Closing (a) for any and all breaches or alleged breaches of any representations, warranties, covenants or agreements of the parties in this Agreement or in any Schedules or certificates delivered pursuant hereto, or (b) otherwise in connection with the transactions contemplated hereby.  This Section 11.07 shall not limit any rights, obligations or remedies available to any party under the Transition Services Agreement or the Web Services Agreement, all of which are expressly preserved.
