5.                                      TERMS AND CONDITIONS OF AWARDS.

Awards shall be evidenced by Award Agreements specifying the number of Rights covered thereby, in such form as the Board shall from time to time establish.  No Award or purported Award shall be a valid and binding obligation of the Company unless evidenced by a fully executed Award Agreement.  Award Agreements may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:

5.1             Strike Price.  The Strike Price shall be established by the Board and set forth in the Award Agreement evidencing an Award.  Unless otherwise specified by the Board in the grant of an Award, each Award shall have a Strike Price equal to one hundred percent (100%) of the Fair Market Value determined as of the Grant Date.

5.2             Vesting of Awards.  Subject to Section 5.4, each Award shall Vest at such time or times, or upon such event or events, and subject to such terms, conditions, performance criteria, and restrictions as shall be determined by the Board and set forth in the Award Agreement evidencing such Award.  The Vesting provisions of individual Awards may vary.  Notwithstanding the foregoing, it is anticipated that Vesting shall be Service-based.

5.3             Effect of Termination of Service.  Subject to earlier termination of the Award as otherwise provided by this Plan and unless a longer exercise period is provided by the Board in the grant of an Award and set forth in the Award Agreement, an Award shall terminate immediately upon the Participant’s termination of Service to the extent that it is then unvested and shall be immediately and automatically exercised upon the Participant’s termination of Service, subject to Section 5.4 and only to the extent it is then Vested only during the applicable time period determined in accordance with this Section and thereafter shall terminate provided, however, that notwithstanding any other provision of the Plan to the contrary, if the Participant’s Service with the Participating Company Group is terminated for Cause, the Award shall terminate and cease to be exercisable immediately upon such termination of Service.

5.4             Exercisability of Awards.  Unless otherwise determined by the Board in its sole discretion or as provided in Section 5.6, each Award shall be exercisable only to the extent that the Award is Vested at the time of exercise.

5.5             Procedure for Exercise of Awards.  Awards shall be exercised by written notice to the Company which must state the election to exercise the Award and the number of Vested Rights for which the Award is being exercised.  The written notice must be in the form approved by the Board, signed by the Participant and delivered in person, by certified or registered mail, return receipt requested, by confirmed facsimile transmission, or by such form of electronic transmission or other means as the Company may permit to an authorized representative of the Company, prior to the termination of the Award.  An Award shall be deemed exercised when the Company receives the written or electronic notice of exercise in

7

the form required by the Board or on such future date as specified by the Participant in such notice and as permitted in accordance with Section 5.4.  An Award may not be exercised for less than one hundred (100) Rights at any one time or, if less, the number of Rights remaining subject to the Award.

5.6             Payment Upon Exercise or Deemed Exercise of Awards.  Upon the exercise of an Award, the Participant (or the Participant’s legal representative or other person who acquired the right to receive payment upon the exercise of the Award by reason of the Participant’s death) shall be entitled to receive payment of an amount for each Right with respect to which the Award is exercised equal to the excess, if any, of the Fair Market Value on the date of exercise of the Award over the Strike Price applicable to the Award.  Payment of such amount shall be made in cash (including a funds transfer) within thirty (30) days following the date of exercise of the Award or such other date as mutually agreed between the Participant and the Company.

5.7             Effect of Termination of Service for Cause.  If a Participant’s Service is terminated for Cause, the Participant’s Award, to the extent not exercised prior to the date of such termination, shall terminate and cease to be exercisable immediately upon such termination of Service, whether Vested or non-Vested.

6.                                      TAXES.

6.1             Tax Withholding.  The Company or its Affiliate shall have the right to withhold from payroll and from any and all amounts payable to a Participant pursuant to the Plan, or require the Participant to remit to the Company or its Affiliate, any and all taxes, if any, required by law to be withheld by a Participating Company with respect to any Award granted to such Participant including, without limitation PRC IIT,  income taxes and social insurances.

6.2             No Guarantee of Tax Consequences.  No person connected with the Plan in any capacity, including, but not limited to any Participating Company, their directors, officers, agents and employees, makes any representation, commitment, or guarantee that any tax treatment, including, but not limited to social insurance contributions, federal, state, local and foreign income, employment, estate and gift tax treatment, will be applicable with respect to amounts deferred under the Plan, or paid to or for the benefit of a Participant under the Plan, or that such tax treatment will apply to or be available to a Participant on account of participation in the Plan.

7.                                      AMENDMENT AND TERMINATION.

The Board may amend, suspend or terminate the Plan at any time.  However, subject to changes in applicable law, regulations or rules that would permit otherwise, without the approval of the Company’s stockholders, there shall be no amendment of the Plan that would require approval of the Company’s stockholders under any applicable law, regulation or rule, including the rules of any stock exchange or market system upon which the Stock may then be listed.  No amendment, suspension or termination of the Plan shall affect any then outstanding

8

Award unless expressly provided by the Board.  Except as provided by the next sentence, no amendment, suspension or termination of the Plan may adversely affect any then outstanding Award without the consent of the Participant.  Notwithstanding any other provision of the Plan to the contrary, the Board may, in its sole and absolute discretion and without the consent of any participant, amend the Plan or any Award Agreement, to take effect retroactively or otherwise, as it deems necessary or advisable for the purpose of conforming the Plan or such Award Agreement to any present or future law, regulation or rule applicable to the Plan.

8.                                      CHANGE IN CONTROL.

8.1                               Effect of Change in Control on Awards.

(a)                                 Accelerated Vesting.  The Board may, in its sole discretion, provide in any Award Agreement or, in the event of a Change in Control, may take such actions as it deems appropriate to provide for the acceleration of the exercisability and vesting in connection with such Change in Control of any or all outstanding Awards and shares acquired upon the exercise thereof upon such conditions, including termination of the Participant’s Service prior to, upon, or following such Change in Control, and to such extent as the Board shall determine.

(b)                                 Assumption or Substitution of Awards.  In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the “Acquiror”), may, without the consent of any Participant, either assume or continue the Company’s rights and obligations under each or any Award or portion thereof outstanding immediately prior to the Change in Control or substitute for each or any such outstanding Award or portion thereof a substantially equivalent award based upon the Acquiror’s stock.

(c)                                  Cash-Out of Awards.  The Board may, in its sole discretion and without the consent of any Participant, determine that, upon the occurrence of a Change in Control, each or any Award outstanding immediately prior to the Change in Control shall be canceled in exchange for a payment with respect to each vested Award (and each unvested Award, if so determined by the Board) of Stock subject to such canceled Award in cash which, in any such case, shall be in an amount having a Fair Market Value equal to the Fair Market Value of the consideration to be paid per share of Stock in the Change in Control over the strike price per share under such Award (the “Spread”).  In the event such determination is made by the Board, the Spread (reduced by applicable withholding taxes, if any) shall be paid to Participants in respect of their canceled Awards as soon as practicable following the date of the Change in Control and in respect of the unvested portion of their canceled Awards in accordance with the vesting schedule applicable to such Awards as in effect prior to the Change in Control.

9.                                      MISCELLANEOUS.

9.1             Adjustments to Awards for Changes in Capital Structure.  In the event of any change in the Stock through merger, consolidation, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off,

9

combination of shares, exchange of shares, dividend in kind or other like change in the capital structure of the Parent or distribution (other than normal cash dividends) to shareholders of the Parent, appropriate adjustments shall be made in the number of Rights subject to each Award, the class of shares to which a Right relates, and in each applicable Fair Market Value in order to prevent dilution or enlargement of a Participant’s rights under the Plan.  Any fractional Right resulting from an adjustment pursuant to this Section shall be rounded to the nearest whole number.  Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive.

9.2             Other Provisions.  Any Award granted under the Plan may also be subject to such other provisions (whether or not applicable to any Award granted to any other Participant) as the Board determines to be appropriate, including, without limitation, to comply with federal, state and foreign securities laws, or understandings or conditions as to the Participant’s employment or service in addition to those specifically provided for under the Plan.

9.3             Nontransferability of Awards.  Prior to payment in settlement of the Award, an Award granted to a Participant shall not be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or garnishment by creditors of the Participant or the Participant’s beneficiary, except by will or by the laws of descent and distribution.  Awards shall be exercisable, during the Participant’s lifetime, only by the Participant.

9.4             Beneficiary Designation.  Each Participant may name, from time to time, a beneficiary to whom any benefit under the Plan is to be paid in case of such Participant’s death before he or she receives any or all of such benefit.  If a married Participant designates a beneficiary other than the Participant’s spouse, the effectiveness of such designation may be subject to the consent of the Participant’s spouse.  Each designation will revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime.  In the absence of any such designation, benefits remaining unpaid at the Participant’s death shall be paid to his or her estate.

9.5             No Right, Title, or Interest in Assets of the Company.  Participants shall have no right, title, or interest whatsoever in any assets of the Company or to any investments which the Company may make to aid it in meeting its obligations under the Plan.  Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company and any Participant, beneficiary, legal representative or any other person.  To the extent that any person acquires a right to receive payments from the Company under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company.  All payments to be made hereunder shall be paid from the general funds of the Company and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in the Plan.

10

9.6             No Right to Continued Service or to Award Grant.  The Participant’s rights, if any, to continue to serve the Company as an employee, officer, director, independent contractor or otherwise, shall not be enlarged or otherwise affected by his or her designation as a Participant under the Plan, and, except as provided in a separate, written agreement between the Participant and the Participating Company employing or engaging the Participant, such Participating Company reserves the right to terminate the Service of any Participant at any time, subject to applicable laws.  The adoption of the Plan shall not be deemed to give any person any right to be selected as a Participant or to be granted an Award.

9.7             No Rights as a Shareholder.  Nothing in the Plan or any Award Agreement shall confer upon any Participant any rights as a member of the Company or as a shareholder of the Parent.

9.8             Awards Subject to Domestic and Foreign Laws.  The Board may grant Awards to Participants who are subject to the tax, securities and other laws of nations other than the China on terms and conditions as determined by the Board as necessary to comply with applicable foreign laws.  The Board may take any action which it deems advisable to obtain approval of such Awards by the appropriate foreign governmental entity; provided, however, that no such Awards may be granted pursuant to this Section 9.8 and no action may be taken which would result in a violation of any applicable law.

9.9             Binding Effect.  Subject to the restrictions on transfer set forth herein, the terms of the Plan and a Participant’s Award Agreement shall inure to the benefit of and be binding upon the Company, the Participant and their respective heirs, executors, administrators, successors and assigns.  The terms of the Plan and a Participant’s Award Agreement shall supersede all prior arrangements, whether written or oral, and understandings regarding the subject matter of the Plan and such Award Agreement.

9.10      Notices.  Any notice required or permitted under the Plan or any Award Agreement shall be given in writing and shall be deemed effectively given upon personal delivery or by registered or certified mail, with postage and fees prepaid, addressed to the other party at the address shown below that party’s signature on the Award Agreement or at such other address as such party may designate in writing from time to time to the other party.

9.11      Other Benefits.  No Award granted under the Plan or income recognized by a Participant upon the exercise of an Award shall be considered compensation for purposes of computing benefits under any present or future retirement or other compensation or benefit plan of any Participating Company or any affiliate thereof nor affect any benefits or compensation under any such plan.

9.12      Governing Law.  The validity, interpretation, construction and performance of the Plan and each Award Agreement shall be governed by the laws of the People’s Republic of China.
