The beneficiary to the Letter is Citibank China Co., Ltd. including all its branches and sub branches (hereinafter referred to as the “Guarantee”).

This Letter is aimed to guarantee, (i) the financing agreement (hereinafter referred to as the “Financing Agreement”) dated October 11^th, 2007 by and between Shenzhen Highpower Technology Co., Ltd. as the borrower (hereinafter referred to as the “Principal Debtor”) and the Guarantee as the loan bank, whereby the Guarantee shall provide the loan with total amount equivalent to USD 2 Million (hereinafter referred to as the “Financing”) to the Principal Debtor; and (ii) the main agreement on deriving deals (hereinafter referred to as the “Main Agreement”, which together with the Financing Agreement are referred to as “Such Agreements”) signed on October 11^th, 2007 by the Principal Debtor as Party B and the Guarantee as Party A.

The terms and expressions used but not otherwise defined in this Letter shall have the same meaning as in the Financing Agreement or the Main Agreement to the extent the same terms and expression are defined therein.

Whereas the Guarantee and Principal Debtor have entered into Such Agreements, the Guarantor agrees as follows:

1

1. Guaranty and Indemnity

The Guarantor unconditionally guarantees to pay any or all outstanding amounts (existing or subsequent amounts) due and payable or to be due and payable by the Principal Debtor under Such Agreements (including any modification or supplement made thereto from time to time as well as any deal confirmation or similar confirmation documents made on reliance of the Main Agreement), with or without other guaranty, that become due as a result of maturity or accelerated repayment or any other reasons. The debt shall include but not limited to principal, interest, charge, default interest, penalty, cost, expenditure, compensation, payment, expense, and any expense or other payment obligations arising from the enforcement by the Guarantee of the rights prescribed hereunder or strict performance of any terms or clauses hereof (all aforesaid obligations are herein referred to as the “Debt”). In the event the Principal Debtor fails to pay full amount of any Debt (at the prescribed due date or any other due date agreed as a result of accelerated repayment or any other reasons), the Guarantor shall, at the request of the Guarantee, pay said Debt to the Guarantee on behalf of the Principal Debtor without any delay, as if the Guarantor had become the Principal Debtor in place of the actual Principal Debtor.

This Letter is a repayment guarantee instead of a guarantee for debt collection. The due and outstanding amounts of debt and expenses set forth on the vouchers produced by the Guarantee shall be final to the Guarantor. As an independent obligation, the Guarantor agrees that if any debt guaranteed by the Guarantor becomes unenforceable, invalid or illegal (whether such circumstance exists now or whether it has become known or may become known to any Party hereto in the future), the Guarantor shall, as a major obligation of the Guarantor and upon request by the Guarantee, immediately indemnify the Guarantee for any cost, loss or indebtedness incurred as a result of such circumstance. The amount of such cost, loss or indebtedness of the Guarantee shall be equal to the amounts otherwise repayable to the Guarantee.
