The aggregate amount of funds used by Magnum to purchase the Magnum Note under the Note Sale Agreement was US$44,045,000.

Item 4.         Purpose of Transaction.

Magnum purchased the Magnum Note under the Note Sale Agreement for investment purposes.

Pursuant to a purchase agreement (the “Magnum Purchase Agreement”), dated as of May 8, 2015, between Magnum and Golden Meditech, Magnum has agreed to sell to Golden Meditech, and Golden Meditech has agreed to purchase from Magnum, the Magnum Note.

Pursuant to the Magnum Purchase Agreement, Magnum will cause the Company to issue to Golden Meditech a 7% senior unsecured convertible note with an aggregate principal amount of US$25,000,000 due 2017 (the “Magnum-GM Note”), without any consideration to the Company. The Magnum Note will be surrendered to the Company for cancellation. Pursuant to the Magnum Purchase Agreement, the Magnum-GM Note will be substantially in the form of the Magnum Note. The conversion price under the Magnum-GM Note will be US$2.838 (as may be adjusted in accordance with its terms), and accordingly, the Magnum-GM Note will entitle Golden Meditech, subject to the terms and conditions thereof, to receive 8,809,020 Ordinary Shares upon conversion of the Magnum-GM Note.

The purchase price for the Magnum-GM Note will be the aggregate of (i) US$5,100,000, (ii) the product of (A) US$6.40 and (B) the total number of Ordinary Shares into which the Magnum Note is convertible (the “Magnum Conversion Shares”) as of the date of completion of the sale of the Magnum Note (the “Magnum Completion Date”), (iii) the total amount of interest accrued but unpaid on the Magnum Note during the period from October 3, 2014 to the Magnum Completion Date and (iv) if the Company declares a dividend or other distribution payable to the holders of Ordinary Shares (a “Distribution”) between the date of the Magnum Purchase Agreement and the Magnum Completion Date, the amount per Ordinary Share of such Distribution multiplied by the number of the Magnum Conversion Shares as of the Magnum Completion Date, to the extent that such Distribution shall not have been paid to Magnum prior to the Magnum Completion Date.

3

If the Final Acquisition Price (as defined below) is higher than US$6.40, Golden Meditech will also pay to Magnum an amount equal to the product of (a) the positive difference between the Final Acquisition Price and US$6.40 and (b) the total number of the Magnum Conversion Shares as of the Magnum Completion Date. The “Final Acquisition Price” means the sum of (x) the consideration per Ordinary Share paid to holders of the Ordinary Shares upon completion of the Acquisition pursuant to the definitive agreements of the Acquisition (including any amendments thereto, if any), and (y) the amount per Ordinary Share of all Distributions declared after the Magnum Completion Date and prior to the closing of the Acquisition, if any. The “Acquisition” refers to the proposed acquisition by Golden Meditech or one of its controlled affiliates of the outstanding Ordinary Shares not currently owned by Golden Meditech or its affiliates pursuant to a merger of the Company with a controlled affiliate of Golden Meditech, resulting in a delisting of the Company from the New York Stock Exchange.

The completion of the sale of the Magnum Note is conditional upon, among other things, Golden Meditech obtaining the approval from Golden Meditech’s shareholders, at a duly convened meeting, of the purchase of the Magnum Note by Golden Meditech, and the termination of the Security Agreement. The completion of the sale of the Magnum Note is not conditional on the closing of the Acquisition or the approval of the Acquisition by the shareholders of the Company or Golden Meditech.
