PRINCIPAL AND SELLING SHAREHOLDERS

     Since the filing on January 24, 2007 by Mindray of Amendment No. 2 to the Registration Statement on Form F-1 (File No. 333-140028) (as amended, the “Registration Statement”) to which this offering and communication relates, certain changes have occurred with respect to the number of ADSs (as defined below) being offered and sold and the information under the caption “Principal and Selling Shareholders” in the Registration Statement. The principal changes are as follows:

	•		New Dragon (No. 12) Investments Limited is now offering 426,319 American depositary shares (“ADSs”), each representing one Class A ordinary share, par value HK$0.001 per share, of Mindray instead of the 855,397 ADSs previously listed in the Registration Statement as being offered for sale by New Dragon (No. 12) Investments Limited;
	•		Quiet Well Limited is now offering 426,319 ADSs instead of the 855,397 ADSs previously listed in the Registration Statement as being offered for sale by Quiet Well Limited;
	•		Scien-Ray (BVI) Incorporated is now offering 852,638 ADSs instead of the 1,710,795 ADSs previously listed in the Registration Statement as being offered for sale by Scien-Ray (BVI) Incorporated; and
	•		Able Choice Investments Limited is now offering 2,434,001 ADSs instead of the 2,351,654 ADSs previously listed in the Registration Statement as being offered for sale by Able Choice Investments Limited. This adjusted ADS number reflects the transfer of 197,597 Class A ordinary shares previously held through Able Choice Investments Limited to City Legend Limited, as well as an increase in the number of ADSs to be offered.

     In addition, the underwriters have an option to purchase up to an additional 1,474,083 ADSs, which would be sold by the selling shareholders substantially on a pro-rata basis.

     Following the changes discussed above, the selling shareholders in the aggregate are offering 9,827,220 ADSs in this offering (excluding those that are issuable upon the exercise of the underwriters’ option to purchase additional ADSs), representing a decrease of 12.9% from the 11,282,003 ADSs previously indicated in the Registration Statement. Immediately after the completion of this offering, there will be a total of 32,827,220 ADSs outstanding (assuming that the underwriters will not exercise their option to purchase additional ADSs in the offering), representing a decrease of 4.2% from the 34,282,003 ADSs previously indicated in the Registration Statement.

     The information under the caption “Principal and Selling Shareholders” in the Registration Statement is amended as follows (other than the subsection therein, “History of Share Capital”, which is not amended hereby):

     The following table sets forth information with respect to the beneficial ownership, within the meaning of Rule 13d-3 under the Exchange Act, of our ordinary shares, as of January 16, 2007, and as adjusted to reflect the sale of the ADSs offered in this offering for:

	•		each of our directors and executive officers who beneficially own our ordinary shares;
	•		each person known to us to own beneficially more than 5% of our ordinary shares; and
	•		each selling shareholder participating in this offering.

     Beneficial ownership includes voting or investment power with respect to the securities. Except as indicated below, and subject to applicable community property laws, the persons named in the table have sole voting and investment power with respect to all ordinary shares shown as beneficially owned by them. Percentage of beneficial ownership is based on 105,727,677 ordinary shares outstanding prior to and immediately after completion of this offering, taking into consideration options exercisable by such person within 60 days after the date of this prospectus.

     The table below does not reflect the exercise of the underwriters’ option to purchase up to an additional 1,474,083 ADSs, which would be sold by the selling shareholders substantially on a pro-rata basis.
