6.3 Indemnification Claims.

(a) (i) If any third party notifies any Indemnified Party with respect to any matter (a “Third Party Claim”) that may give rise to a claim for indemnification against an Indemnifying Party under Article VI, then the Indemnified Party shall promptly give written notification to the Indemnifying Party thereof. Such notification shall be given within ten (10) business days after receipt by the Indemnified Party of notice of such Third Party Claim, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Claim and the amount of the claimed damages (if available); provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent that the Indemnifying Party’s ability to defend has been irreparably prejudiced by such failure.

(ii) The Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified Party; provided that (A) the Indemnifying Party

notifies the Indemnified Party in writing within fifteen (15) 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 Damages the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim (subject to the provisions of this Article VI); (B) the ad damnum, if any, is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VI; (C) 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; (D) the Third Party Claim does not involve criminal liability and seeks only money damages and not equitable relief against the Indemnified Party; (E) 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 or the reputation of the Indemnified Party, and (F) the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently.

(iii) If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Claim, the Indemnified Party shall control such defense.

(iv) 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 Claim 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 Claim (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 Claim. The reasonable fees and expenses of counsel to the Indemnified Party with respect to a Third Party Claim shall be considered Damages for purposes of this Agreement if (x) the Indemnified Party controls the defense of such Third Party Claim pursuant to the terms of this Section 6.3(a) or (y) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Claim.

(v) The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Claim without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld or delayed; provided that the consent of the Indemnified Party shall not be required if the Indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or judgment and such settlement or judgment includes a complete release of the Indemnified Party from further liability and has no other adverse effect on the Indemnified Party. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld or delayed.

(b) Within twenty (20) days after delivery of the notification of a Third Party Claim as provided in Section 6.3(a)(i) (a “Claim Notice”), the Indemnifying Party shall deliver to the Indemnified Party a Response, in which the Indemnifying Party shall (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer), or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount.

(c) During the 30-day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such 30-day period, the Indemnifying Party and the Indemnified Party shall discuss in good faith the submission of the Dispute to binding arbitration, and if the Indemnifying Party and the Indemnified Party agree in writing to submit the Dispute to such arbitration, then the provisions of Section 6.3(d) shall become effective with respect to such Dispute. The provisions of this Section 6.3(c) shall not obligate the Indemnifying Party and the Indemnified Party 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 Indemnifying Party and the Indemnified Party to arbitrate a Dispute, such Dispute shall be resolved in a state or federal court sitting in the State of Delaware, in accordance with Section 10.11.

(d) If, as set forth in Section 6.3(c), the Indemnified Party and the Indemnifying Party agree to submit any Dispute to binding arbitration, the arbitration shall be conducted by a single arbitrator (the “Arbitrator”) in accordance with the Commercial Rules 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 Los Angeles, California of the AAA in accordance with Commercial Rule 5 (or any successor provision).

(iii) No depositions or other discovery shall be conducted in connection with the arbitration.

(iv) Not later than thirty (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 (subject to Section 10.11), provided that the Arbitrator shall have no power or authority to (x) award damages in excess of the portion of the Claimed Amount that is subject to such Dispute, (y) award multiple, consequential, punitive or exemplary damages, or (z) grant injunctive relief, specific performance or other equitable relief.

(v) 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 6.3(d), or (y) address or resolve any issue not submitted by the parties.

(vi) In connection with any arbitration proceeding pursuant to this Agreement, the own costs and expenses of the prevailing party, 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 shall be paid by the non-prevailing party or as otherwise determined by the Arbitrator.

(e) Notwithstanding the other provisions of this Section 6.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VI, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VI and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VI, for any such Damages for which it is entitled to indemnification pursuant to this Article VI (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VI).

6.4 Survival of Representations, Warranties and Covenants.

(a) The representations and warranties made by the Company in this Agreement or any certificate required to be delivered at Closing to Purchaser, and the representations and warranties of Purchaser or any certificate required to be delivered at Closing to the Company, and the covenants and agreements of the Company and Purchaser which by their terms do not contemplate performance after the Closing Date, shall survive the Closing and remain in full force and effect until June 15, 2008.

(b) The rights to indemnification set forth in this Article VI shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after 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 an Indemnified Party of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants.

6.5 Limitations.

(a) The Company shall not have any obligation to indemnify Purchaser from and against any Damages under Section 6.1, other than Damages resulting by reason of a breach of Sections 2.1, 2.2 or 2.5 or any fraud or intentional misrepresentation, until the Purchaser Indemnitees have suffered Damages by reason of all such breaches in excess of One Million United States Dollars ($1,000,000) (after which point the Company will be obligated to indemnify the Purchaser Indemnitees from and against all such Damages) and such indemnification obligation shall not exceed Twenty-Five Million United States Dollars ($25,000,000) except with respect to a breach of Sections 2.1, 2.2 or 2.5 or in the case of fraud or intentional misrepresentation.

(b) Purchaser shall not have any obligation to indemnify the Company Indemnitees from and against Damages under Section 6.2, other than Damages resulting by reason of a breach of Sections 3.1 or 3.2 or any fraud or intentional misrepresentation, until the Company Indemnitees have suffered Damages by reason of all such breaches in excess of a One Million United States Dollars ($1,000,000) aggregated deductible (after which point Purchaser will be obligated to indemnify the Company Indemnitees from and against all such Damages) and such indemnification obligation shall not exceed Twenty-Five Million United States Dollars ($25,000,000) except with respect to a breach of Sections 3.1 or 3.2 or in the case of fraud or intentional misrepresentation.

(c) The rights of the Indemnified Parties under this Article VI shall be the exclusive remedy of the Indemnified Parties with respect to any and all matters arising out of, relating to, or connected with this Agreement, the Company and its Subsidiaries and their respective assets and liabilities; provided, however, that notwithstanding any other provision of this Agreement, nothing herein shall limit any claim of any Party for remedies at law or in equity for fraud or intentional misrepresentations.

(d) The amount of Damages recoverable by an Indemnified Party under this Article VI shall be reduced by any proceeds received by such Indemnified Party or an Affiliate, with respect to the Damages to which such indemnity claim relates, from an insurance carrier or any third party. Each Indemnified Party shall use its Reasonable Best Efforts to seek payment or reimbursement for any Damages from its insurance carrier or other collateral sources. In the event that an Indemnified Party shall receive funds from any insurance carrier or collateral source with respect to any Damages, any such amounts so received shall be payable to the Indemnifying Party, regardless of when received by the Indemnified Party, up to such amount previously paid by the Indemnifying Party or their Affiliates with respect to such Damages.

(e) Notwithstanding anything to the contrary contained in this Agreement, following a determination that the Indemnifying Party is obligated to indemnify the Indemnified Party pursuant to Sections 6.1 or 6.2(a), and subject to the threshold amounts set forth in Sections 6.5(a) or 6.5(b), and solely for purposes of determining the amount of any Damages that are the subject matter of a claim for indemnification hereunder, each representation and warranty in this Agreement and each certificate of document delivered pursuant hereto shall be read without regard and without giving effect to the term(s) “material” or “Material Adverse Effect” in each instance where the effect of such term(s) would be to make such representation and

warranty less restrictive (as if such words and surrounding related words (e.g., “reasonably be expected to,” “could have”) and similar restrictions and qualifiers were deleted from such representations and warranty).

6.6 Treatment of Indemnification Payments. The Parties hereto agree to treat all indemnification payments made pursuant to this Article VI (including, without limitation, payments pursuant to Sections 6.1 and 6.2) as adjustments to the Purchase Price for all income Tax purposes and to take no position contrary thereto in any Tax Return or audit or examination by, or proceeding before, any taxing authority, except as required by a change in law or a “determination” as defined in Section 1313 of the Code and the Treasury Regulations thereunder.

(iv) any action taken or omitted by the Company or any failure of any Party to assert any claim or demand or to enforce any right or remedy against the Company; or

(v) other action or circumstance (including, without limitation, any statute of limitations) or any existence of or reliance on any representation by the Company that might otherwise constitute a defense available to, or a legal or equitable discharge of, any co-obligor or any other guarantor or surety.

(c) The Guarantor acknowledges and agrees that (i) it will receive substantial direct and indirect benefits from the arrangements contemplated in this Agreement which would not have been available to Purchaser except upon the basis set forth herein and with the Guarantee provided in this Article VII and (ii) the Company has made no representation or warranty with respect to validity, genuineness, regularity, or enforceability of this Agreement or any of the Purchaser Related Documents, and has no duty or responsibility whatsoever to the Guarantor in respect to the management and maintenance of the Guaranteed Obligations.

10.8 Governing Law. All matters arising out of or relating to this Agreement and the transactions contemplated hereby (including without limitation its interpretation, construction, performance and enforcement) shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdictions other than those of the State of Delaware.

10.9 Amendments and Waivers. The Parties may mutually amend any provision of this Agreement at any time prior to the Closing. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by all of the Parties. No waiver of any right or remedy hereunder shall be valid unless the same shall be in writing and signed by the Party giving such waiver. No waiver by any Party with respect to any default, misrepresentation or breach of warranty or covenant hereunder shall be valid unless the same shall be in writing and signed by the Party making such waiver nor shall such waiver be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

10.10 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified.

10.11 Submission to Jurisdiction. Each Party (a) submits to the jurisdiction of any state or federal court sitting in the State of Delaware in any action or proceeding arising out of or relating to this Agreement (including any action or proceeding for the enforcement of any arbitral award made in connection with any arbitration of a Dispute hereunder), (b) agrees that all claims in respect of such action or proceeding may be heard and determined in any such court, (c) waives any claim of inconvenient forum or other challenge to venue in such court, (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other

court and (e) waives any right it may have to a trial by jury with respect to any action or proceeding arising out of or relating to this Agreement; provided in each case that, solely with respect to any arbitration of a Dispute, the Arbitrator shall resolve all threshold issues relating to the validity and applicability of the arbitration provisions of this Agreement, contract validity, applicability of statutes of limitations and issue preclusion, and such threshold issues shall not be heard or determined by such court. Each Party agrees to accept service of any summons, complaint or other initial pleading made in the manner provided for the giving of notices in Section 10.7, provided that nothing in this Section 10.11 shall affect the right of any Party to serve such summons, complaint or other initial pleading in any other manner permitted by law.

10.12 Construction.

(a) The language used in this Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent, and no rule of strict construction shall be applied against any Party.
