7.2.2 Losses. The term "Losses" as used in this Article VII is not limited to matters asserted by third parties against any Purchaser Indemnified Party but includes Losses incurred or sustained by a Purchaser Indemnified Party in the absence of Third Party Claims (as defined in Section 7.4.2 hereof).

Section 7.3 Obligation of the Purchaser to Indemnify. Subject to the limitations set forth in Section 7.6.3 hereof, the Purchaser hereby agrees to indemnify Kenna Holdco, Kenna and the Kenna Principals (individually a "Company Indemnified Party" and collectively, the "Company Indemnified Parties") against, and to protect, save and keep harmless the Company Indemnified Parties from, and to pay on behalf of or reimburse the Company Indemnified Parties as and when incurred for, any and all Losses that may be imposed on or incurred by the Company Indemnified Parties as a consequence of, in connection with, incident to, resulting from or arising out of or in any way related to or by virtue of: (a) any misrepresentation, inaccuracy or breach of any warranty or representation of the Purchaser contained in Article IV hereof or in any certificate delivered by the Purchaser at the Closing; or (b) any action, demand, proceeding, investigation or claim by any third party (including any Governmental or Regulatory Authority) against or affecting any Company Indemnified Party which may give rise to or evidence the existence of or relate to a misrepresentation or breach of any of the representations and warranties of the Purchaser contained in Article IV hereof or in any certificate delivered by the Purchaser at the Closing; or (c) any breach or failure by the Purchaser to comply with, perform or discharge any obligation, agreement or covenant by the Purchaser contained in this Agreement.

Section 7.4 Indemnification Procedures.

7.4.1 Non-Third Party Claims.

(a) In the event that any Person entitled to indemnification under this Agreement (an "Indemnified Party") asserts a claim for indemnification which does not involve a Third Party Claim (as defined in Section 7.4.2) (a "Non-Third Party Claim"), against which a Person is required to provide indemnification under this Agreement (an "Indemnifying Party"), the Indemnified Party shall give written notice to the Indemnifying Party (the "Non-Third Party Claim Notice"), which Non-Third Party Claim Notice shall (i) describe the claim in reasonable detail, and (ii) indicate the amount (estimated, if necessary, and to the extent feasible) of the Losses that have been or may be suffered by the Indemnified Party.

(b) The Indemnifying Party may acknowledge and agree by written notice (the "Non-Third Party Acknowledgement of Liability") to the Indemnified Party to satisfy the Non-Third Party Claim within 30 days of receipt of the Non-Third Party Claim Notice. In the event that the Indemnifying Party disputes the Non-Third Party Claim, the Indemnifying Party shall provide written notice of such dispute (the "Non-Third Party Dispute Notice") to the Indemnified Party within 30 days of receipt of the Non-Third Party Claim Notice (the "Non-Third Party Dispute Period"), setting forth a reasonable basis of such dispute. In the event that the Indemnifying Party shall fail to deliver the Non-Third Party Acknowledgement of Liability or Non-Third Party Dispute Notice within the Non-Third Party Dispute Period, the Indemnifying Party shall be deemed to have acknowledged and agreed to pay the Non-Third Party Claim in full and to have waived any right to dispute the Non-Third Party Claim. Once the Indemnifying Party has acknowledged and agreed to pay any Non-Third Party Claim pursuant to this Section 7.4.1, or once any dispute under this Section 7.4.1 has been finally resolved in favor of indemnification by a court or other tribunal of competent jurisdiction, subject to the provisions of Section 7.6.1, the Indemnifying Party shall pay the amount of such Non-Third Party Claim to the Indemnified Party within 10 days of the date of acknowledgement or resolution, as the case may be, to such account and in such manner as is designated in writing by the Indemnified Party.

7.4.2 Third-Party Claims.

(a) In the event that any Indemnified Party asserts a claim for indemnification or receives notice of the assertion of any claim or of the commencement of any action or proceeding by any Person who is not a party to this Agreement or an affiliate of a party to this Agreement in respect of which such Indemnified Party is entitled to indemnification by an Indemnifying Party under this Agreement (a "Third Party Claim"), the Indemnified Party shall give written notice to the Indemnifying Party (the "Third Party Claims Notice") within 20 days after asserting or learning of such Third Party Claim (or within such shorter time as may be necessary to give the Indemnifying Party a reasonable opportunity to respond to such claim), together with a statement specifying the basis of such Third Party Claim. The Third Party Claim Notice shall (i) describe the claim in reasonable detail, and (ii) indicate the amount (estimated, if necessary, and to the extent feasible) of the Losses that have been or may be suffered by the Indemnified Party. The Indemnifying Party must provide written notice to the Indemnified Party that it is either (i) assuming responsibility for the Third Party Claim or (ii) disputing the claim for indemnification against it (the "Indemnification Notice") The Indemnification Notice must be provided by the Indemnifying Party to the Indemnified Party within 15 days after receipt of the Third Party Claims Notice or within such shorter time as may be necessary to give the Indemnified Party a reasonable opportunity to respond to such Third Party Claim (the "Indemnification Notice Period").

(b) If the Indemnifying Party provides an Indemnification Notice to the Indemnified Party within the Indemnification Notice Period that it assumes responsibility for the Third Party Claim (the "Defense Notice"), the Indemnifying Party shall conduct at its expense the defense against such Third Party Claim in its own name, or if necessary in the name of the Indemnified Party. The Defense Notice shall specify the counsel the Indemnifying Party will appoint to defend such claim ("Defense Counsel"); provided, however, that the Indemnified Party shall have the right to approve the Defense Counsel, which approval shall not be unreasonably withheld or delayed, except that such approval may be withheld if the defense is to be in the name of the Indemnified Party. In the event that the Indemnifying Party fails to give the Indemnification Notice within the Indemnification Notice Period, the Indemnified Party shall have the right to conduct the defense and to compromise and settle such Third Party Claim without the prior consent of the Indemnifying Party and subject to the provisions of Section 7.6.1, the Indemnifying Party will be liable for all costs, expenses, settlement amounts or other Losses paid or incurred in connection therewith.

(c) In the event that the Indemnifying Party provides in the Indemnification Notice that it disputes the claim for indemnification against it, the Indemnified Party shall have the right to conduct the defense and to compromise and settle such Third Party Claim, without the prior consent of the Indemnifying Party. Once such dispute has been finally resolved in favor of indemnification by a court or other tribunal of competent jurisdiction or by mutual agreement of the Indemnified Party and Indemnifying Party, subject to the provisions of Section 7.6.1, the Indemnifying Party shall within 10 days of the date of such resolution or agreement, pay to the Indemnified Party all Losses paid or incurred by the Indemnified Party in connection therewith.

(d) In the event that the Indemnifying Party delivers an Indemnification Notice pursuant to which it elects to conduct the defense of the Third Party Claim, the Indemnifying Party shall be entitled to have the exclusive control over the defense of the Third Party Claim and the Indemnified Party will cooperate in good faith with and make available to the Indemnifying Party such assistance and materials as it may reasonably request, all at the expense of the Indemnifying Party. The Indemnified Party shall have the right at its expense to participate in the defense assisted by counsel of its own choosing. The Indemnifying Party will not settle the Third Party Claim or cease to defend against any Third Party Claim as to which it has delivered an Indemnification Notice (as to which it has assumed responsibility for the Third Party Claim), without the prior written consent of the Indemnified Party, which consent will not be unreasonably withheld or delayed; provided, however, such consent may be withheld if, among other reasons, as a result of such settlement or cessation of defense, (i) injunctive relief or specific performance would be imposed against the Indemnified Party, or (ii) such settlement or cessation would lead to liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder.

(e) If an Indemnified Party refuses to consent to a bona fide offer of settlement which the Indemnifying Party wishes to accept, which provides for a full release of the Indemnified Party and its affiliates relating to the Third Party Claims underlying the offer of settlement and solely for a monetary payment, the Indemnified Party may continue to pursue such matter, free of any participation by the Indemnifying Party, at the sole expense of the Indemnified Party. In such an event, the obligation of the Indemnifying Party shall be limited to the amount of the offer of settlement which the Indemnified Party refused to accept plus the reasonable costs and expenses of the Indemnified Party incurred prior to the date the Indemnifying Party notified the Indemnified Party of the offer of settlement.

(f) Notwithstanding clause (d) above, the Indemnifying Party shall not be entitled to control, but may participate in, and the Indemnified Party shall be entitled to have sole control over, the defense or settlement of (x) that part of any Third Party Claim that (i) seeks a temporary restraining order, a preliminary or permanent injunction or specific performance against the Indemnified Party, (ii) involves criminal allegations against the Indemnified Party or (iii) may lead to liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder and (y) the entire Third Party Claim if such Third Party Claim would impose liability on the part of the Indemnified Party in an amount which is greater than the amount as to which the Indemnified Party is entitled to indemnification under this Agreement.

(g) A failure by an Indemnified Party to give timely, complete or accurate notice as provided in this Section 7.4 will not affect the rights or obligations of any party hereunder except and only to the extent that, as a result of such failure, any party entitled to receive such notice was deprived of its right to recover any payment under its applicable insurance coverage or was otherwise directly and materially damaged as a result of such failure to give timely notice.

Section 7.5 Right of Offset. Without limiting any other rights or remedies available to it, the Purchaser shall be entitled to offset any claim for indemnity made pursuant to Section 7.2 and in accordance with Section 7.4, against any Contingent Payment or Top-Up Payment due to Kenna Holdco, subject to an aggregate limit of $3,000,000; provided, however, the Purchaser may only exercise such right of offset in respect of claims relating to Losses actually incurred by a Purchaser Indemnified Party (in which case the amount of such offset shall be the amount of such actual Loss) or claims actually asserted by a third party (in which case the amount of the offset shall not exceed the Purchaser's good faith estimate of the amount of indemnifiable Losses that will ultimately be payable to a Purchaser Indemnified Party in respect of such claims).

Section 7.6 Limitations On and Other Matters Regarding Indemnification

7.6.1 Indemnity Cushion and Cap. Subject to Section 7.6.5, neither Kenna Holdco nor any of the Kenna Principals shall have any liability to any Purchaser Indemnified Party with respect to Losses arising out of any of the matters referred to in Section 7.2 until such time as the amount of such liability shall exceed $100,000 in the aggregate (in which case Kenna Holdco and the Kenna Principals shall be liable for all Losses). Notwithstanding anything to the contrary herein, subject to Section 7.6.5 below, the maximum aggregate liability of Kenna Holdco and the Kenna Principals for indemnity payments under Section 7.2.1 shall be an aggregate amount equal to the sum of (A) $750,000 plus (B) $3,000,000 of the Contingent Payments and the Top-Up Payments paid or payable pursuant to this Agreement.

7.6.3 Termination of Indemnification Obligations of the Purchaser; Purchaser Indemnity Cap. The obligation of the Purchaser to indemnify under Section 7.3 hereof shall terminate on March 31, 2012, except as to matters as to which Kenna Holdco or the Kenna Principals have made a claim for indemnification on or prior to such date, in which case the right to indemnification with respect thereto for such party shall survive the expiration of such period until such claim for indemnification is finally resolved and any obligations with respect thereto are fully satisfied.
