Annex 2—Pricing Method for Selling Price of Separately-packaged Regent of Party B

Purpose: to determine the pricing method for separately-packaged regent of Party B sold to Party A

Application: separately-packaged regent of Party B sold to Party A

1. Pricing Principle for List Price of Separately-packaged Regent of Party B

The list price of separately-packaged regent of Party B is calculated according to the following formula:

(cost of separately-packaged regent of Party B + labor and packaging cost)/(1- gross profit rate) = the list price of separately-packaged regent of Party B

* The gross profit rate is 42%.

2. Cost Calculation Method for Raw Materials of Separately-packaged Regent of Party B

single reagent purchase cost of Party B/(single regent purchase quantity of Party B /deadstock quotient/specification of separately-packaged regent) = cost of raw materials of separately-packaged regent of Party B

* The deadstock quotient is 2.

Example: Party B singly purchases 1,000 grams regent at the purchase cost of 2,000 yuan and divides them into 50 grams/bottle. The cost of raw materials of separately-packaged regent per bottle shall be calculated at 2,000 / (1,000/2/50)=200 yuan.

3. Labor and Packaging Cost of Party B

The labor and packaging cost of Party B is calculated at 10 yuan/package unit.

4. Separate Package Specification Reference of Party B

Party B calculates the cost of raw materials of separately-packaged regent per gram based on the single purchase cost of separately-packaged regent/single regent purchase quantity of Party B * deadstock quotient, and determines the separate package specification according to the following table:

Raw Materials Cost for Separately- Packaged Regent Per Gram

³50 yuan

³10 yuan

³5 yuan

³2 yuan

³1 yuan

³0.35 yuan

³0.2 yuan

<0.2 yuan

Note: The table is a basic reference for separate package specification, without referring to which

Party B may conduct separate package for regent at Party A’s request or due to other reasons.

5. Selling Price to Party A of Separately-packaged Regent of Party B

Party B’s selling price to Party A shall be 30% lower than the list price of separately-packaged regent of Party B, or Party B sells separately-packaged regent to Party A at a price up to 70% of list price of separately-packaged regent.

6. Rebate Method of Separately-packaged Regent

Party B shall pay as rebate Party A 15% of the total purchase amount of separately-packaged regent if the package unit of the single type regent of the same separate package specification reaches or exceeds 20.

The said rebate shall be calculated once for all on December 31 annually and deducted from the logistics service fee paid by Party A to Party B.

4) testing shall be exercised at 10% testing rate for regent purchased from supplies with long-term cooperation and quality guarantee;

5) testing shall be exercised at 10% testing rate for each batch of regent which has been separately packaged by suppliers before purchase; or

6) testing may or may not be required for imported regent in original packaging.

The above regulations are subject to modification. Party A has the right to require Party B to increase testing rate for the regent of certain type if Party A’s synthesis staff notice quality problems in the regent several times. Party B shall automatically save the spectrogram information for qualified products after testing and shall provide relevant spectrogram information in a timely manner at the request of Party A’s synthesis staff. Subject to the agreement hereof, Party B shall compensate Party A if Party A finds that certain regent does not meet quality standard in the process of purchase or application of the regent of Party B.
