SECTION 8.01. Survival of Representations and Warranties; Indemnification.

(a) All representations and warranties contained in this Agreement shall be deemed made at the Closing as if made at such time and shall survive for twelve (12) months after having been made or deemed made, except that (i) with respect to claims asserted pursuant to this Section 8.01 before the expiration of the applicable representation or warranty, such claims shall survive until the date they are finally liquidated or otherwise resolved, (ii) Section 4.14 shall survive until 120 days after the expiration of the applicable statute of limitations for the tax liabilities in question and (iii) Sections 4.01, 4.02, 4.03, 4.04, 4.05(a)(i), 4.16, 5.01, 5.02 and 5.03(a)(i) shall survive indefinitely. A claim shall be made or commenced hereunder by the Indemnified Party (as defined below) delivering to the Indemnifying Party (as defined below) a written notice specifying in reasonable detail the nature of the claim, the amount claimed (if known or reasonably estimable), and the factual basis for the claim.

(b) The Company agrees to indemnify and hold harmless the Investor and its officers, directors, employees, duly authorized agents and affiliates from and against all losses, claims, damages, diminution in value of the Shares, expenses (including reasonable counsel fees and disbursements) or liabilities (“Losses”) that are related to or arise out of (1) any breach by the Company of any of its representations or warranties in this

Agreement or (2) failure to perform any of the covenants or agreements made by the Company in this Agreement. The term “Losses” as used in this Section 8.01 is not limited to matters asserted by third parties against an Indemnified Party, but includes Losses incurred or sustained by an Indemnified Party in the absence of third party claims, and shall be net of any tax benefit available to the Indemnified Party.

(c) The Investor agrees to indemnify and hold harmless the Company and its officers, directors, employees, duly authorized agents and affiliates from and against all Losses that are related to or arise out of (1) any breach by the Investor of any of its representations or warranties in this Agreement or (2) failure to perform any of the covenants or agreements made by the Investor in this Agreement.

(d) Notwithstanding anything to the contrary contained in this Agreement: (i) an Indemnifying Party shall not be liable for any claim for indemnification pursuant to this Section 8.01 with respect to any breach of any representation or warranty, unless and until the aggregate amount of indemnifiable Losses which may be recovered from the Indemnifying Party equals or exceeds $100,000, after which the Indemnifying Party shall be liable for the entire aggregate amount of any such indemnifiable Losses; (ii) with respect to any breach of any representation or warranty, the maximum amount of indemnifiable Losses which may be recovered from an Indemnifying Party arising out of or resulting from the causes set forth in Section 8.01 shall be an amount equal to the aggregate price actually paid for the Tranche 1 Shares and the Tranche 2 Shares and (iii) neither party hereto shall have any liability under any provision of this Agreement or any Ancillary Agreement for any punitive damages.

(e) A party claiming indemnification under this Agreement (an “Indemnified Party”) with respect to any claims asserted against the Indemnified Party by a third party (“Third Party Claim”) that would give rise to a right of indemnification under this Agreement shall promptly (i) notify the party from whom indemnification is sought (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any) and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party demonstrates actual and material prejudice as a result of such failure. The Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim provided that such Indemnifying Party has acknowledged in writing its obligation to fully indemnify the Indemnified Party with respect to such Third Party Claim pursuant to this Section 8.01.

(f) If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third Party Claim, then the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected by the Indemnifying Party, who is reasonably acceptable to the Indemnified Party, by all appropriate proceedings, which proceedings shall be prosecuted reasonably diligently by the Indemnifying Party to a final conclusion or settled at the discretion of the Indemnifying Party in accordance with this Section 8.01(f). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof, provided, however, that the Indemnifying Party shall not consent to the entry of a judgment or enter into any settlement with respect to the matter (i) which does not contain a complete release of the Indemnified Party, contains a finding of responsibility or liability on the part of the Indemnified Party or the violation of any applicable legal requirement, provides any material sanction or material restriction upon the conduct of any business by the Indemnified Party, or provides for any relief other than monetary damages which are paid in full by the Indemnifying Party or (ii) without the prior written consent of the Indemnified Party, which consent shall not be unreasonably conditioned, withheld or delayed. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the person asserting the Third Party Claim or any cross-complaint against any person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 8.01, and the Indemnified Party shall bear its own costs and expenses with respect to such participation; provided, however, if in the opinion of counsel of the Indemnified Party there is a

reasonable likelihood of a conflict of interest between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall bear the reasonable costs and expenses of one counsel to represent all Indemnified Party in connection with such defense. Notwithstanding the foregoing, the Indemnifying Party shall not be entitled to assume the defense of any Third Party Claim if the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the Indemnified Party that the Indemnified Party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages.

(g) If the Indemnifying Party fails to notify the Indemnified Party within the thirty (30) days after receipt of any Claim Notice that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 8.01(f), or if the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 8.01(f) but fails to reasonably diligently defend or settle the Third Party Claim, then the Indemnified Party shall have the right to defend the Third Party Claim by all appropriate proceedings, which proceedings shall be promptly and vigorously defended by the Indemnified Party to a final conclusion or settled (with the reasonable costs and expenses of such defense borne by the Indemnifying Party). The Indemnified Party shall have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent, which shall not be unreasonably withheld or delayed. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 8.01(g), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(h) In the event any Indemnified Party should have a claim against any Indemnifying Party hereunder which does not involve a Third Party Claim, the Indemnified Party shall promptly transmit to the Indemnifying Party a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the claim, the Indemnified Party’s best estimate of the amount of Losses attributable to such claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. If the Indemnifying Party does not notify the Indemnified Party within thirty (30) days from its receipt of the Indemnity Notice that the Indemnifying Party disputes such claim (the “Dispute Notice”), the Indemnifying Party shall be deemed to have accepted and agreed with such claim. If the Indemnifying Party has disputed such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution to such dispute. If the Indemnifying Party and the Indemnified Party cannot resolve such dispute in thirty (30) days after delivery of the Dispute Notice, such dispute shall be resolved by litigation in an appropriate court of competent jurisdiction.

(i) The parties agree to treat all indemnification payments made under this Section 8.01 or otherwise under this Agreement as an adjustment to the applicable purchase price for tax purposes and that such treatment shall govern for purposes hereof except to the extent that the Laws of a particular jurisdiction provide otherwise, in which case such payments shall be made in an amount sufficient to indemnify the relevant party on an after-tax basis.

(j) Subject to Section 8.01(k) below, notwithstanding any other term herein, and other than in connection with fraud, the sole and exclusive remedies of the parties arising out of, relating to or resulting from any breach of any representation, warranty, covenant or agreement in this Agreement will be strictly limited to those contained in this Article VIII.

(k) Each Party acknowledges and agrees that the other Party will be damaged irreparably if this Agreement is not performed in accordance with its terms or otherwise is breached and that a party will be entitled to seek an injunction and other equitable relief to prevent breaches hereof and to enforce specifically this Agreement and its terms in addition to such Party’s remedies as set forth in Article VIII.

SECTION 9.02. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions be consummated as originally contemplated to the fullest extent possible.

SECTION 9.03. Entire Agreement; Assignment. This Agreement and the Ancillary Agreements

constitute the entire agreement between the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between the parties with respect to the subject matter hereof and thereof. This Agreement shall not be assigned by operation of law or otherwise without the prior written consent of the other party.

SECTION 9.04. Disclosures. The parties hereto agree that any information contained in any part of any SEC Report shall only be deemed to be an exception to (or a disclosure for purposes of) the Company’s representations and warranties if the relevance of that information as an exception to (or a disclosure for purposes of) such representations and warranties would be reasonably apparent to a person who has read that information concurrently with such representations and warranties. In no event shall any general information contained in any part of any SEC Report entitled “Risk Factors” or containing a general description or explanation of “Forward-Looking Statements” (or any other statements that are similarly non-specific or are predictive or forward-looking in nature) be deemed to be a specific exception to (or a disclosure for purposes of) any representations and warranties of the Company contained in this Agreement unless the relevance of that information (for purposes as an exception to a disclosure for purposes of such representations and warranties) would be reasonably apparent.

SECTION 9.05. Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

SECTION 9.06. Governing Law. This Agreement shall be governed by, and construed in accordance with, the Laws of the State of Delaware. All actions and proceedings arising out of or relating to this Agreement shall be heard and determined exclusively in any Delaware state or federal court, in each case sitting in City of Wilmington, New Castle County. The parties hereto hereby (a) submit to the exclusive jurisdiction of any Delaware state or federal court, in each case sitting in City of Wilmington, New Castle County, for the purpose of any Action arising out of or relating to this Agreement brought by any party hereto and (b) irrevocably waive, and agree not to assert by way of motion, defense or otherwise, in any such Action, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the Action is brought in an inconvenient forum, that the venue of the Action is improper or that this Agreement or the Transactions may not be enforced in or by any of the above-named courts.

SECTION 9.07. Waiver of Jury Trial. Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the Transactions. Each of the parties hereto (a) certifies that no representative, agent or attorney of the other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other party hereto have been induced to enter into this Agreement and the Transactions, as applicable, by, among other things, the mutual waivers and certifications in this Section 9.07.

SECTION 9.08. Attorneys’Fees. If any legal action is brought by reason of any breach of any covenant, condition or agreement of the parties in this Agreement or the Ancillary Agreements, the prevailing party shall be entitled to recover from the other party to the action all costs and expenses of suit, including attorneys’ fees.

SECTION 9.09. Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.
