Section 6.03 . Company Employee Plans.

(d) The rights of each Indemnified Person under this Section shall be in addition to any rights such Person may have under the articles of incorporation, bylaws or similar organizational documents of the Company or any of the Company Subsidiaries, under CA Law or any other applicable laws or under the applicable Indemnification Agreement or any other agreement of any Indemnified Person with the Company or any of the Company Subsidiaries.

Such notification shall be given as soon as practicable after receipt by Buyer of notice of such Third Party Action, and shall describe in reasonable detail (to the extent known by Buyer) the facts constituting the basis for such Third Party Action and the amount of the claimed damages; provided, however , that no delay or failure on the part of Buyer in so notifying the Stockholders’ Representative shall relieve the Stockholders of any indemnification obligations hereunder except to the extent of any Damages caused by or arising out of such delay or failure or to the extent such delay or failure will have adversely prejudiced the Stockholders. Buyer will promptly provide the Stockholders’ Representative with such additional information with respect thereto that the Stockholders’ Representative may reasonably request. Within 20 days after delivery of such notification, the Stockholders’ Representative may, upon written notice thereof to Buyer, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to Buyer (it being understood and agreed that the law firms listed in Section 10.02 of the Company Disclosure Schedule shall be deemed reasonably satisfactory to Buyer); provided that (i) the Stockholders’ Representative may only assume control of such defense if (A) it acknowledges in writing to Buyer that any Damages that may be assessed against Buyer in connection with such Third Party Action constitute Damages for which Buyer shall be indemnified pursuant to and subject to the limitations of this Article 10 and (B) the Third Party Action is reasonably likely to result in an amount that is less than or equal to the amount of Damages to which Buyer may be entitled under this Article 10 and (ii) the Stockholders’ Representative may not assume control of the defense of a Third Party Action involving criminal liability or in which equitable relief is sought against Buyer. If the Stockholders’ Representative does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, Buyer shall control such defense. The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The reasonable fees and expenses of counsel to Buyer with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) Buyer controls the defense of such Third Party Action pursuant to the terms of this Section 10.02(a) or (ii) the Stockholders’ Representative assumes control of such defense and Buyer reasonably concludes that the Stockholders and Buyer have conflicting interests or different defenses available with respect to such Third Party Action. The Stockholders’ Representative shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of Buyer, which shall not be unreasonably withheld, conditioned or delayed. Buyer shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Stockholders’ Representative, which shall not be unreasonably withheld, conditioned or delayed.

(b) In order to seek indemnification under this Article 10, Buyer (i) must act in good faith and (ii) shall deliver as soon as reasonably practicable a Claim Notice to the Stockholders’ Representative, with a copy to the Escrow Agent.

(c) Within 20 days after delivery of a Claim Notice, the Stockholders’ Representative shall deliver to Buyer a response (the “ Response ”), in which the Stockholders’ Representative shall: (i) agree that Buyer is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a written notice instructing the Escrow Agent to distribute to Buyer a portion of the Escrow Amount equal to the Claimed Amount), (ii) agree that Buyer is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a written notice instructing the Escrow Agent to distribute to Buyer a portion of the Escrow Amount equal to the Agreed Amount) or (iii) dispute that Buyer is entitled to receive any of the Claimed Amount.

(d) During the 30-day period following the delivery of a Response that reflects a Dispute, the Stockholders’ Representative and Buyer shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such 30-day period, the Stockholders’ Representative and Buyer shall discuss in good faith the submission of the Dispute to binding arbitration, and if the Stockholders’ Representative and Buyer agree in writing to submit the Dispute to such arbitration, then, unless agreed in such written agreement, the provisions of Section 10.02(e) shall become effective with respect to such Dispute. The provisions of this Section 10.02(d) shall not obligate the Stockholders’ Representative and Buyer to submit to arbitration or any other alternative dispute resolution procedure with respect to any Dispute, and in the absence of an agreement by the Stockholders’ Representative and Buyer to arbitrate a Dispute, such Dispute shall be resolved in a state or federal court sitting in California, in accordance with Section 11.07. The Stockholders’ Representative and Buyer shall deliver to the Escrow Agent, promptly following the resolution of the Dispute (whether by mutual agreement, arbitration, judicial decision or otherwise), a written notice executed by both parties instructing the Escrow Agent as to what (if any) portion of the Escrow Amount shall be distributed to Buyer (which notice shall be consistent with the terms of the resolution of the Dispute).

(e) If, as set forth in Section 10.02(d), Buyer and the Stockholders’ Representative agree to submit any Dispute to binding arbitration, then unless otherwise agreed between Buyer and the Stockholders’ Representative, the arbitration shall be conducted by a single arbitrator (the “ Arbitrator ”) in accordance with the Commercial Arbitration Rules (“ Commercial Rules ”) of the American Arbitration Association (“ AAA ”) in effect from time to time and the following provisions:

(i) In the event of any conflict between the Commercial Rules in effect from time to time and the provisions of this Agreement, the provisions of this Agreement shall prevail and be controlling.

(ii) The parties shall commence the arbitration by jointly filing a written submission with the San Francisco office of the AAA in accordance with Commercial Rule 5 (or any successor provision).

(iii) Not later than 30 days after the conclusion of the arbitration hearing, the Arbitrator shall prepare and distribute to the parties a writing setting forth the arbitral award and the Arbitrator’s reasons therefor. Any award rendered by the Arbitrator shall be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction.

(iv) The Arbitrator shall have no power or authority, under the Commercial Rules or otherwise, to (x) modify or disregard any provision of this Agreement, including the provisions of this Section 10.02(e), or (y) address or resolve any issue not submitted by the parties.

(v) In connection with any arbitration proceeding pursuant to this Agreement, each party shall bear its own costs and expenses, except that the fees and costs of the AAA and the Arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the Arbitrator may determine to be directly related to the conduct of the arbitration and appropriately borne jointly by the parties (which shall not include any party’s attorneys’ fees or costs, witness fees (if any), costs of investigation and similar expenses) shall be shared equally by Buyer and the Stockholders.

(f) Notwithstanding the other provisions of this Section 10.02, if a customer asserts (other than by means of a lawsuit) that Buyer is liable to such customer for a monetary or other obligation which may constitute or result in Damages for which Buyer may be entitled to indemnification pursuant to this Article 10, and Buyer reasonably determines that it has a valid business reason to fulfill such obligation, then (i) Buyer shall be entitled to satisfy such obligation, without prior consent from the Stockholders’ Representative, (ii) Buyer may subsequently make a claim for indemnification in accordance with the provisions of this Article 10, and (iii) Buyer shall be reimbursed, in accordance with the provisions of this Article 10, for any such Damages for which it is entitled to indemnification pursuant to and subject to the limitations of this Article 10 (including subject to the right of the Stockholders’ Representative to dispute Buyer’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article 10).

(g) The Stockholders’ Representative shall have full power and authority on behalf of each Stockholder, and holder of In-the-Money Options to take any and all actions on behalf of, execute any and all instruments on behalf of, and execute or waive any and all rights of, such Persons under this Article 10. The Stockholders’ Representative shall have no liability to any Person for any action taken or omitted on behalf of the Stockholders and holders of In-the-Money Options pursuant to this Article 10.

Section 10.03 . Survival of Representations and Warranties. All representations and warranties that are covered by the indemnification agreements in Section 10.01(a) shall (a) survive the Closing and (b) shall expire on the date 12 months following the Closing Date. If Buyer delivers to the Stockholders’ Representative, before expiration of a representation or warranty, either a Claim Notice based upon a breach of such representation or warranty, or an Expected Claim Notice based upon a breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of any claims arising from or related to the matter covered by such notice. If the legal proceeding or written claim with respect to which an Expected Claim Notice has been given is definitively withdrawn or resolved in favor of Buyer, Buyer shall promptly so notify the Stockholders’ Representative; and if Buyer has delivered a copy of the Expected Claim Notice to the Escrow Agent and a portion of the Escrow Amount has been retained in escrow after the 12-month anniversary of the Closing Date with respect to such Expected Claim Notice, the Stockholders’ Representative and Buyer shall promptly deliver to the Escrow Agent a written notice executed by both parties instructing the Escrow Agent to distribute such retained Escrow Amount to the Stockholders in accordance with the terms of the Escrow Agreement. The rights to indemnification set forth in this Article 10 shall not be affected by (i) any investigation conducted by or on behalf of Buyer or any knowledge acquired (or capable of being acquired) by Buyer, whether before or after the date of this Agreement or the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by Buyer of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants. All representations and warranties of Buyer and MergerCo contained herein shall terminate at the Effective Time.

Section 10.04 . Limitations. (a) Notwithstanding anything to the contrary herein after the Closing, except in the case of fraud, (i) the Stockholders shall have no liability of any kind to Buyer, any Affiliate of Buyer or the Surviving Corporation, subject only to Buyer’s right to bring indemnification claims solely and exclusively against the Escrow Account pursuant to this Article 10 and the Escrow Agreement, and Buyer’s rights under this Article 10 shall be the sole and exclusive remedy of Buyer, any Affiliate of Buyer or the Surviving Corporation, (ii) Buyer shall not be entitled to make an indemnification claim under this Article 10 for any individual claim if the Damages relating to such claim do not exceed $20,000, (iii) Buyer shall be entitled to make indemnification claims under this Article 10 only with respect to that portion of the aggregate Damages under this Article 10 for which Buyer would otherwise be entitled which exceeds $600,000; provided that the limitations set forth in this Section 10.04(a)(ii) and Section 10.04(a)(iii) shall not apply to claim pursuant to Section 10.01(c), Section 10.01(d) or Section 10.01(e), and provided further that any claim pursuant to Section 10.01(c), Section 10.01(d) or Section 10.01(e), shall not be taken into account in calculating the portion of the aggregate Damages that exceeds $600,000, if any, (iv) the maximum amount of Damages to which Buyer shall be entitled in respect of all indemnification claims under this Article 10 shall not exceed, and shall be payable solely and exclusively from, the Escrow Amount, and (v) the maximum amount of damages for any indemnification claim by Buyer shall not exceed, and shall be payable solely from the Available Escrow Amount at the time such indemnification claim is made hereunder. For purposes solely of this Article 10, all representations and warranties of the Company in Article 3 (other than Section 3.08(a)) shall be construed as if references to “material” or “Material Adverse Effect” (and variations thereof) were omitted from such representations and warranties.

(b) Without limiting the rights of any Indemnified Person pursuant to Section 6.06 hereof, no Stockholder shall have any right of contribution against the Company or the Surviving Corporation with respect to any breach by the Company of any of its representations, warranties, covenants or agreements.

(c) Buyer, its Affiliates and the Surviving Corporation shall use reasonable efforts prior to any distribution from the Escrow Account to seek to mitigate to the extent required by applicable law, any Damages for which Buyer seeks indemnification under this Agreement; provided that the cost of such mitigation shall be taken into account in determining the applicable Damages.

(d) Buyer, its Affiliates and the Surviving Corporation shall use reasonable efforts to collect any amounts available under insurance coverage of any Damages payable under this Article 10; provided that Buyer shall not be required in any event to commence legal proceedings for such collection.

(e) Buyer shall not be entitled to any claim for Damages under this Article 10 attributable to or resulting from Buyer causing or permitting the Company, any Subsidiary of the Company or any Affiliate of Buyer to make or change any Tax election, amend any Return or take any Tax position on any Return, take any action, omit to take any action or enter into any transaction, merger or restructuring that results in any increased Tax liability or reduction of any Tax Asset of the Buyer, any Affiliate of Buyer, the Company or any Subsidiary of the Company.

Section 10.05 . Calculation of Damages. (a) Any amount of any Damages payable under this Article 10 from the Escrow Account shall be net of any amounts recovered, or acknowledged by the applicable insurance carrier to be recoverable, by Buyer and its Affiliates under applicable insurance policies. If Buyer or its Affiliates receive any amounts under applicable insurance policies subsequent to an indemnification payment from the Escrow Account, then Buyer shall promptly pay and reimburse the Stockholders, holders of In-the-Money Options and the Participants (as if such payment was a distribution from the Escrow Account for the benefit of such holders) for any such indemnification payment from the Escrow Account up to the amount received by Buyer or its Affiliates, net of any expenses incurred by Buyer or its Affiliates in collecting such amount including the cost of any premium increases resulting from Damages so recovered under the applicable insurance policies.

(b) Buyer shall not be entitled under this Article 10 to any Damages relating to any matter to the extent (i) that there is included in the September Balance Sheet a specific liability or reserve relating to such matter, or (ii) of consequential (other than Damages for lost profits) or punitive Damages; provided that, without limiting the right of the Stockholders’ Representative to dispute Buyer’s entitlement to indemnification or the amount for which it is entitled to indemnification under the terms of this Article 10, sub-section (ii) of this Section 10.05(b) shall not apply in the event that Buyer or the Surviving Corporation is liable to a third party for Damages which constitute consequential or punitive Damages and for which Buyer, but for this Section 10.05(b), would have been entitled to seek indemnification under the terms and subject to the limitations of this Article 10.
