Notwithstanding the foregoing or anything in this Agreement to the contrary, the term "Damages" shall in no event include any loss of profits or business opportunity, or any indirect, special or consequential damages however caused. 7.9 CLAIM FOR INDEMNIFICATION. (a) Subject to Section 7.9(b), any claim for indemnification must be made by written notice to the party against whom indemnification is sought. Such notice shall specify in reasonable detail the particulars of the claim for indemnity and the basis upon which indemnity is claimed. Any claim for indemnification shall be paid in cash. The aggregate value of the indemnification payments made by any party hereunder shall be limited to: (1) 40% of the Purchase Price, for Damages other than pursuant to or resulting from: 21 (i) Sections 7.8(a)(iii), (v) (only to the extent Damages are caused by the acts or omissions of S1) and (vi) hereof, or (ii) any breach of a covenant contained in Sections 6.1(a)-(n), 7.10, 7.11 or 7.14 hereof, or (iii) any inaccuracy or breach of a representation or warranty contained in Sections 3.10, 3.19 or 4.4 hereof (subsections (i), (ii) and (iii) together, the "EXCEPTED DAMAGES"), and (2) the Purchase Price for the Excepted Damages, provided, however, that the aggregate value of the indemnification payments made by any party hereunder shall in no event exceed the Purchase Price. Notwithstanding the foregoing, the aggregate value of the indemnification payments, if any, made by S1 with respect to any Damages arising under Section 7.8(a)(iv) shall be unlimited. Except as provided in Section 10.7, the indemnification provisions contained in Section 7.8, Section 7.11 and this Section shall constitute the sole and exclusive remedy for Damages resulting from any inaccuracy or breach of a representation or warranty or breach of any covenant or agreement made by Purchaser, S1 or Davidge pursuant to this Agreement. Notwithstanding anything herein to the contrary, no claims for Damages shall be asserted, and no party shall be liable for any claim for indemnification hereunder, other than with respect to Damages pursuant to Sections 7.8(a)(iii), (iv), (v) and (vi) hereof, unless and until the aggregate amount of Damages that would otherwise be payable exceeds $200,000 (the "DEDUCTIBLE AMOUNT"), in which case the Seller shall be liable for all such Damages. In calculating the Deductible Amount or Damages hereunder, other than with respect to Damages pursuant to Sections 7.8(iii), (iv), (v) and (vi) hereof, all Damages which total less than $17,500 with respect to any single claim for Damages shall be excluded in their entirety, and the indemnified party shall have no recourse for such Damages. If any event shall occur which would otherwise entitle Purchaser to assert a claim for indemnification hereunder, no Damages shall be deemed to have been sustained to the extent of (i) any net proceeds received by the indemnified party from any insurance policy with respect thereto, (ii) any net recovery received by the indemnified party from third parties with respect thereto, or (iii) any tax benefit realized by the indemnified party with respect thereto. S1 and Purchaser shall take all reasonable steps to mitigate damages in respect of any claim for which they are seeking indemnification, including, without limitation, using commercially reasonable efforts to effect recovery from third parties and of available insurance claims in connection with such claim. (b) Indemnification Procedures for Third Party Claims. (i) If any third party shall notify any party (the "INDEMNIFIED PARTY") with respect to any matter (a "THIRD PARTY CLAIM") which may give rise to a claim for indemnification against any other party (the "INDEMNIFYING PARTY") under this Agreement, then the Indemnified Party shall promptly notify each Indemnifying Party thereof in writing; provided, however, that no delay on the part of the Indemnified Party in notifying any Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party thereby is prejudiced. (ii) Any Indemnifying Party will have the right to defend the Indemnified Party against the Third Party Claim with counsel of its choice so long as (A) the Indemnifying Party notifies the Indemnified Party in writing within 30 days after the Indemnified Party has given notice of the Third Party Claim that the Indemnifying Party will indemnify the Indemnified Party from and against the entirety of any Damages the Indemnified Party may suffer resulting from, arising 22 out of, relating to, in the nature of, or caused by the Third Party Claim, (B) the Indemnifying Party provides the Indemnified Party with evidence 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 (not to be unreasonably withheld), (C) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief, and (D) the Indemnifying Party is conducting the defense of the Third Party Claim actively and diligently (provided, that in the event the Indemnified Party does not believe that the Indemnifying Party is conducting the defense of the Third Party Claim actively and diligently, the Indemnified Party may upon reasonable advance notice to the Indemnifying Party, with an opportunity to cure any identified deficiency, defend itself with counsel of its choice, at the Indemnifying Party's expense). In the event counsel to the Indemnifying Party identifies a conflict of interest in connection with such counsel's representation of the Indemnifying Party, the Indemnifying Party shall take all necessary measures to resolve the conflict, including, but not limited to selecting new counsel. (iii) So long as the Indemnifying Party is conducting the defense of the Third Party Claim in accordance with Section 7.9(b)(ii) above, (A) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (B) the Indemnified Party will not 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 Indemnifying Party (not to be withheld unreasonably), and (C) the Indemnifying Party will not 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 Indemnified Party (not to be withheld unreasonably). (iv) In the event any of the conditions in Section 7.9(b)(ii) above is or becomes unsatisfied, however, (A) 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 reasonably may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, any Indemnifying Party in connection therewith), (B) the Indemnifying Parties will reimburse the Indemnified Party promptly and periodically for the costs of defending against the Third Party Claim (including reasonable attorneys' fees and expenses), and (C) the Indemnifying Parties will remain responsible for any Damages the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim to the fullest extent provided in this Agreement. 7.10 POST-CLOSING COOPERATION. Purchaser and S1 shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns following the Closing and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information which are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser shall fully cooperate with S1 in the completion of all of Davidge's books and records for any period prior to the Closing Date. Purchaser and S1 further agree (A) to retain all books and records with respect to Tax matters pertinent to Davidge relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser or S1, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (B) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, Purchaser or S1, as the case may be, shall allow the other party to take possession of such books and records. 23 7.11 TAX MATTERS. (a) Any tax sharing agreement to which Davidge and S1 are parties shall be terminated as of the Closing Date and after the Closing Date neither party shall have any liability to the other thereunder. S1 shall indemnify and hold harmless Davidge and Purchaser against any loss, cost or liability arising from the inclusion of Davidge in any consolidated tax return of S1 or any consolidated group of which S1 is or was a member. (b) S1 shall include the income (or losses) of Davidge on consolidated federal income Tax Returns for the affiliated group of which S1 is the common parent (the "S1 GROUP") for all periods through the end of the Closing Date ("CONSOLIDATED RETURN PERIODS") and pay any federal Income Taxes attributable to such income. Following the Closing, Davidge shall furnish Tax information to S1 for inclusion in the S1 Group's federal consolidated income Tax Return for the Consolidated Return Period that includes the Closing Date in accordance with past custom and practice. The income (or losses) of Davidge shall be apportioned to Consolidated Return Periods and periods after the Closing Date ("SEPARATE RETURN PERIODS") by closing the books of Davidge as of the end of the Closing Date. S1 will allow Purchaser an opportunity to review and comment upon such Tax Returns (including any amended returns) to the extent they relate to Davidge. (c) If the S1 Group has a consolidated net operating loss, a consolidated net capital loss, a consolidated unused investment credit, a consolidated unused foreign tax credit or a consolidated excess charitable contribution (each as defined in the Regulations and each a "CARRYFORWARD TAX ATTRIBUTE") that can be carried to a Separate Return Period, then the portion, if any, of such Carryforward Tax Attribute that is attributable to Davidge shall be determined in accordance with Section 1.1502-79 of the Regulations. For purposes hereof, "REGULATIONS" means the Treasury Regulations promulgated pursuant to the U.S. Internal Revenue Code.

For purposes of this Section, "CONTROL" means the ability (through the ownership of securities or similar interests, by contract or otherwise and whether or not exercised) to elect a majority of the board of directors or similar governing body of a person.
