Notwithstanding anything to the contrary herein, absent fraud, intentional misrepresentation and willful misconduct:

(a) the maximum aggregate monetary liability of the Seller Parties to the Indemnified Parties for any indemnification under this Agreement and the other Transaction Documents shall not exceed the Purchase Price actually paid by such Investors.

(b) if the losses suffered by the Indemnified Parties are, individually or in the aggregate less than US$50,000 (or its equivalent in other currencies), the Seller Parties shall not be required to indemnify the Indemnified Parties for such losses.

(c) in any event the Founders’ indemnification obligation under this Agreement and the other Transaction Documents is secondary to the Group Companies.

(d) the Founders may, in their sole discretion, elect to satisfy the entirety of their obligation under this Agreement and the other Transaction Documents by transferring the Ordinary Shares in whole or in part held by the BVI Companies to the Indemnified Parties at no cost, which shall be the exclusive remedy of the Indemnified Parties upon such election by the Founders. For the avoidance of doubt, the indemnification obligations of the other Seller Parties shall be unaffected by this Section 8.04(d).
