loan in the principal amount of US$20,000,000 (the “Mandatory Convertible Loan”) by March 31, 2008
pursuant to the terms and conditions set forth in this Section 3.01. The Company may exercise the
Mandatory Additional Investment Right by delivering to Carlyle a written notice setting forth the
date on which Carlyle will be required to extend the Mandatory Convertible Loan (the “Loan
Extension Date”), which written

11

 

notice shall be received by Carlyle no later than 5 Business Days prior to the Loan Extension
Date.

     (b) On or before the Loan Extension Date, the Company and Carlyle shall enter into a loan
agreement (the “Mandatory Convertible Loan Agreement”) with customary terms and conditions
(including customary closing conditions such as the absence of any Material Adverse Effect between
the Closing Date and the Loan Extension Date), including the following terms:

     (i) The Mandatory Convertible Loan shall bear interest on the principal amount from
the Loan Extension Date to the earlier of (A) the date on which the Mandatory Convertible
Loan is paid in full and (B) the date the Mandatory Convertible Loan is converted pursuant
to the conversion right set forth in Section 3.01(b)(iii) or Section 3.01(b)(iv), at a
rate per annum equal to 9%, computed on the basis of a 360-day year and the actual number
of days elapsed.

     (ii) Unless the Mandatory Convertible Loan is converted pursuant to Section
3.01(b)(iii) or Section 3.01(b)(iv), the principal amount of and the accrued interest on
the Mandatory Convertible Loan shall be repaid by the Company on December 31, 2009. The
Company may not prepay the Mandatory Convertible Loan prior to December 31, 2009.

Convertible Loan into a number of Ordinary Shares (the “Conversion Shares”) as follows:

     (A) Carlyle shall have the right, at its sole option, to convert the
Mandatory Convertible Loan into the Conversion Shares at any time during a
period starting from (and including) the day which immediately follows the
Closing Date to (and including) August 31, 2008. If Carlyle exercises such
conversion right, the Mandatory Convertible Loan shall be converted into a
number of Conversion Shares equal to (x) the Pre-Conversion Shares multiplied by
(y) a ratio, the numerator of which is the Mandatory Loan Conversion Amount, and
the denominator of which is equal to (I) RMB1,100,000,000 minus (II) the
Mandatory Loan Conversion Amount, subject to Carlyle’s right to acquire
additional Ordinary Shares from the Controlling Shareholders pursuant to Section
4.04; and

     (B) Carlyle shall have the right, at its sole option, to convert the
Mandatory Convertible Loan into the Conversion Shares at any time during a
period starting from (and including) the date on which the 2008 Audited
Financial Statements are completed to (and including) April 29, 2009. If
Carlyle exercises

12

 

such conversion right, the Mandatory Convertible Loan shall be converted
into a number of Conversion Shares equal to (x) the Pre-Conversion Shares
multiplied by (y) a ratio, the numerator of which is the Mandatory Loan
Conversion Amount, and the denominator of which is equal to (I) 10 times of the
2008 Net Income (as defined below) minus (II) the Mandatory Loan Conversion
Amount.

     (iv) If the IPO Date occurs after August 31, 2008 but prior to the completion of the
2008 Audited Financial Statements and the Mandatory Convertible Loan is outstanding as of
the IPO Date, the Mandatory Convertible Loan shall be automatically converted, on the IPO
Date, into a number of Ordinary Shares equal to (x) the Pre-Conversion Shares multiplied
by (y) a ratio, the numerator of which is the Mandatory Loan Conversion Amount, and the
denominator of which is equal to (I) 10 times the projected consolidated after-tax net
income of the Company for the Company’s fiscal year ending December 31, 2008, as disclosed
to the public in the IPO (provided that the result of the calculation in this clause (I)
shall not exceed a  the number of the outstanding Ordinary Shares immediately prior to
the IPO Date multiplied by (μ) the lower end of the last price range disclosed to the
public in connection with the IPO) minus (II) the Mandatory Loan Conversion Amount,
subject to Carlyle’s right to acquire additional Ordinary Shares from the Controlling
Shareholders pursuant to Section 4.04.

     Section 3.02. Optional Additional Investment. If the Company has not exercised the Mandatory
Additional Investment Right by March 31, 2008, Carlyle shall have the right (the “Optional
Additional Investment Right”) to purchase and subscribe for, at any time by August 31, 2008, a
number of Series A Shares (the “Additional Carlyle Purchased Shares”) for US$20,000,000. The
Additional Carlyle Purchased Shares shall equal to (x) the number of outstanding Ordinary Shares as
of the date of such purchase immediately prior to the consummation of such purchase, calculated on
a Fully-Diluted basis (which for the purposes of this Section 3.02 shall exclude any Ordinary
Shares issuable upon the exercise of any employee stock options), multiplied by (y) a ratio, the
numerator of which is equal to the RMB equivalent of US$20,000,000 calculated with the spot
exchange rate between US dollars and RMB as quoted by the People’s Bank of China on the date of
such purchase (the “Additional Carlyle Purchase Price”), and the denominator of which is equal to
(i) RMB1,100,000,000 minus (ii) the Additional Carlyle Purchase Price. In order to exercise the
Optional Additional Investment Right, Carlyle shall deliver a written notice to the Company no
later than 5 Business Days prior to the proposed purchase date set forth in such notice.
