SECTION 4.3. Indemnity.

(a) The Company shall indemnify the Investors and their respective Affiliates (collectively, the “Investor Indemnified Parties”) and hold each of them harmless against any actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith, and including reasonable attorneys’ fees and disbursements (the “Losses”) suffered, incurred or paid by the Investor Indemnified Parties arising from: (i) any breach of any representation or warranty made by the Company in SECTION 2.1 to be true and correct as of the date hereof and as of the Closing Date; or (ii) any breach of any covenant or agreement by the Company contained in this Agreement. Other than with respect to fraud, in no event shall the Company be liable for or have an obligation to indemnify or hold harmless the Investor Indemnified Parties for Losses (i) in connection with the representations and warranties in SECTION 2.1(a), SECTION 2.1(b) and SECTION 2.1(d) (collectively, the “Fundamental Representations”) in excess of the Aggregate Purchase Price paid to the Company pursuant to this Agreement and (ii) in connection with the representations and warranties other than the Fundamental Reps in excess of US$30,000,000, and the Company shall not be liable to the Investor Indemnified Parties for any Losses unless the aggregate amount of all Losses incurred by the Investor Indemnified Parties exceeds US$1,500,000 in the aggregate (the “Basket”), in which case the Company shall be liable for all such Losses in excess of the Basket. The Company shall not be liable to the Investor Indemnified Parties for any Losses arising under this SECTION 4.3 relating to an individual claim resulting in Losses in the amount of US$100,000 or less (a “De Minimis Claim”), regardless of whether or not aggregate Losses have exceeded the Basket; nor shall the amount of any such De Minimis Claims be taken into account in determining whether the Basket has been reached. Notwithstanding anything to the contrary, in no event shall the aggregate liability of the Company to the Investor Indemnified Parties for any Losses in connection with the Transaction Documents and the transactions contemplated thereby exceed the Aggregate Purchase Price.

(b) Each Investor shall indemnify each of the Company and its Affiliates and each of their respective directors, officers, employees and shareholders, owners (collectively, the “Company Indemnified Parties”) and hold each of them harmless against any and all Losses suffered, incurred or paid by the Company Indemnified Parties, arising from, as a result of or in connection with (i) any failure of any representation or warranty made by such Investor in SECTION 2.2(e) or SECTION 2.2(j) to be true and correct as of the date hereof and as of the Closing Date.

18

(c) A party entitled to indemnification hereunder (an “Indemnified Party”) shall give written notice to the indemnifying party (the “Indemnifying Party”) of any claim with respect to which it seeks indemnification promptly after the discovery by such Indemnified Party of any matters giving rise to a claim for indemnification; provided that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this SECTION 4.3 unless and to the extent that the Indemnifying Party shall have been actually materially prejudiced by the failure of such Indemnified Party to so notify such party. No claim for indemnification may be asserted against any Indemnifying Party for breach of any representation, warranty, covenant or agreement contained herein unless written notice of such claim is received by such Indemnifying Party on or prior to the date on which the representation, warranty, covenant or agreement on which such claim or proceeding is based ceases to survive as set forth in SECTION 6.1. Such notice shall describe in reasonable detail such claim. In case any such action, suit, claim or proceeding is brought against an Indemnified Party, the Indemnified Party shall be entitled to hire, at the cost and expense of the Indemnifying Party, counsel and conduct the defense thereof; provided, however, that the Indemnifying Party shall only be liable for the legal fees and expenses of one law firm for the Indemnified Parties, taken together with regard to any single action or group of related actions, upon agreement by the Indemnified Parties and the Indemnifying Party. If the Indemnifying Party assumes the defense of any claim, the Indemnified Parties shall thereafter deliver to the Indemnifying Party copies of all notices and documents (including court papers) received by the Indemnified Parties relating to the claim, and the Indemnified Parties shall cooperate in the defense or prosecution of such claim. Such cooperation shall include the retention and (upon the Indemnifying Party’s request) the provision to the Indemnifying Party of records and information that are reasonably relevant to such claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Indemnifying Party shall not be liable for any settlement of any action, suit, claim or proceeding effected without its written consent; provided, however, that the Indemnifying Party shall not unreasonably withhold, delay or condition its consent. The Indemnifying Party further agrees that it will not, without any Indemnified Party’s prior written consent (which shall not be unreasonably withheld or delayed), settle or compromise any claim or consent to entry of any judgment in respect thereof in any pending or threatened action, suit, claim or proceeding in respect of which indemnification has been sought hereunder unless such settlement or compromise includes an unconditional release of such Indemnified Party from all liability arising out of such action, suit, claim or proceeding.

(d) In calculating the amount of any Losses hereunder, there shall be subtracted the amount of any insurance proceeds and third-party payments received by the Indemnified Parties with respect to such Losses, if any, net of any actual costs or expenses incurred in connection with securing or obtaining such proceeds or payments. In no event shall any Indemnified Party be entitled to recover or make a claim for any amounts in respect of, and in no event shall “Losses” be deemed to include, consequential or indirect damages, lost profits or punitive damages and, in particular, no “diminution of value”, “multiple of profits” or “multiple of cash flow” or similar valuation methodology shall be used in calculating the amount of any Losses, unless in any such case, such Losses are awarded to a third party.

(e) Absent a showing of fraud by a party, and assuming the Closing has occurred, the indemnification obligation of a party under this SECTION 4.3 shall be the sole and exclusive remedy of any other party against such party for monetary damages for breach of any representation, warranty, covenant or agreement contained in this Agreement or any of the transactions contemplated hereby. Nothing herein shall limit a party’s right to seek injunctive or other equitable relief in connection with the enforcement of this Agreement.

19

(f) Any indemnification payments pursuant to this SECTION 4.3 shall be treated as an adjustment to the investment amount for the Purchased Shares for U.S. federal income and applicable state and local tax purposes, unless a different treatment is required by applicable law.

SECTION 4.4. Registration Rights. At the Closing, the Company, the Investors and the other parties thereto will each enter into the Registration Rights Agreement, substantially in the form attached as Exhibit B hereto.

SECTION 6.10. Captions. The article, section, paragraph and clause captions herein are for convenience of reference only, do not constitute part of this Agreement and will not be deemed to limit or otherwise affect any of the provisions hereof.

SECTION 6.11. Severability. If any provision of this Agreement is found to be invalid or unenforceable, then such provision shall be construed, to the extent feasible, so as to render the provision enforceable and to provide for the consummation of the transactions contemplated hereby on substantially the same terms as originally set forth herein, and if no

24

feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement, which shall remain in full force and effect unless the severed provision is essential to the rights or benefits intended by the parties. In such event, the parties shall use commercially reasonable efforts to negotiate, in good faith, a substitute, valid and enforceable provision.

SECTION 6.12. No Third-Party Beneficiaries. Nothing contained in this Agreement, expressed or implied, is intended to confer or shall confer upon any person other than the express parties hereto, any benefit, right or remedies. The representations and warranties set forth in Article II and the covenants set forth in Articles III and IV have been made solely for the benefit of the parties to this Agreement and (a) may be intended not as statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate; and (b) may apply standards of materiality in a way that is different from what may be viewed as material by shareholders of, or other investors in, the Company.

The parties hereto will not issue any such press release or make any such public statement without the prior written consent of the other party, except as may be required by law or any listing agreement with or requirement of the Nasdaq or any other applicable securities exchange, provided that the disclosing party shall, to the extent permitted by applicable law or any listing agreement with or requirement of the Nasdaq or any other applicable securities exchange, inform the other party about the disclosure to be made pursuant to such requirements prior to the disclosure.

SECTION 6.14. Specific Performance. The parties hereto acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms. It is accordingly agreed that the parties shall be entitled to seek specific performance of the terms hereof, this being in addition to any other remedies to which they are entitled at law or equity.
