Explanation of Difference in Compensation for the Land

The following are the primary reasons as to why the actual amount compensated for the land that we purchased differed by a total of RMB 194,541.21 from the originally calculated price of RMB 3,774,585.21:

1.              We calculated the compensatory amount required for the land coded B-8-1 to be 9 * the actual amount paid / 50, namely 9 * 9,260,755.2 / 50 = RMB 1,666,935.93. After communicating with the Management Committee, they agreed to compensate our company a total of RMB 1,664,000 for the land coded B-8-1, which amounts to a difference in compensation of RMB 2,935.93.

2.              We calculated the compensatory amount for the land coded B-9-3 to be 11 * contract amount / 50, namely 11 * 9,580,224 / 50 = RMB 2,107,649.28. After communicating with the Management Committee, they agreed to compensate our company a total of 10 * contract amount / 50 for the land coded B-9-3, namely 10 * 9,580,224 / 50 = RMB 1,916,044. The means of compensation for this land was to adjust the original land purchase price of RMB 192 per square meter to RMB 153.6 (192 / 50 *4). Thus the total land purchase price went from RMB 9,580,224 to RMB 7,664,180, which amounts to a difference in compensation of RMB 191,605.28.

Analysis of primary reasons for the [price] difference: When calculating [the price] for the land coded B-9-3, we determined the difference in the lifespan to be 11 years, as the actual lifespan is from December 2010 to February 2050. The Management Committee followed its convention of performing calculations on only an annual basis; hence, the difference [in the lifespan] was determined to be 10 years. Adding to that the amount of compensation taken for the land coded B-8-1 has resulted in a final difference in compensation of RMB 194,541.21.

Supplemental Agreement

Both parties of the agreement hereunder:

Party A: Nanjing Xingang Hi-Tech Company Limited (hereinafter referred to as “Party A”)

Party B: Amphastar Nanjing Pharmaceuticals Co., Ltd. (hereinafter referred to as “Party B”)

On December 29, 2009, Party A and Party B signed a “Transfer Contract for the Right to the Use of State-owned Land (NKTZHZ [2009] No.012)” with respect to the land coded B-8-1 located in the Nanjing Economic and Technological Development Zone; on December 31, 2010, Party A and Party B signed a “Transfer Contract for the Right to the Use of State-owned Land (NKTZHZ [2010] No.016)” as well as a “Supplemental Agreement” with respect to the land coded B-9-3 located in the Nanjing Economic and Technological Development Zone. Due to the fact that the land coded B-8-1 and the land coded B-9-3 only have a lifespan of 41 years and 40 years, respectively, Party A shall provide reasonable compensation to Party B for the two parcels of land which have less than 50 years of land use rights. After thorough consultation, Party A and Party B are hereby entering into the following agreement with respect to the transfer and assignment of the right to the use of the state-owned land in the land parcels B-8-1 and B-9-3:

Article I: Actual Transfer Price of Land

1.1 The transfer price for the right to the use of the land coded B-8-1 is adjusted to: RMB 157.70 (in traditional Chinese: RMB one hundred fifty-seven and seventy fen) per square meter. The total transfer price is thus RMB 7,596,750 (in traditional Chinese: RMB seven million five hundred ninety-six thousand seven hundred fifty), which differs from the actual amount paid by Party B when the land B-8-1 was assigned by a total of RMB 1,664,000 (in traditional Chinese: RMB one million six hundred sixty-four thousand). The balance shall serve as a reasonable means of compensation from Party A to Party B to discount the transfer price for the right to the use of the land coded B-9-3.

1.2 The transfer price for the right to the use of the land coded B-9-3 is adjusted to: RMB 153.60 (in traditional Chinese: RMB one hundred fifty-three and sixty fen) per square meter. The total transfer price is thus RMB 7,664,180 (in traditional Chinese: RMB seven million six hundred sixty-four thousand one hundred eighty) (the final amount shall be calculated on the basis of the area as specified in the Land Certificate). The compensatory price of the land coded

1

B-8-1 in the amount of RMB 1,664,000 (in traditional Chinese: RMB one million six hundred sixty-four thousand) shall be deducted from the total transfer price; thus the total payable by Party B for the transfer of the right to the use of the land coded B-9-3 is RMB 6,000,180 (in traditional Chinese: RMB six million one hundred eighty).

1.3 Party B shall make a one-time payment to Party A for the land transfer in the amount of RMB 6,000,180 (in traditional Chinese: RMB six million one hundred eighty) within 30 days upon the signing of this agreement.

1.4 Upon completion of the aforementioned payment, Party B shall apply for the State-owned Land Use Right Certificate from the Nanjing Municipal Bureau of State-owned Land and Resources.

Upon receiving the “State-owned Land Use Right Certificate,” Party B is entitled to transfer and lease the land or use it as collateral in accordance with the law.
