AGREEMENT AND MUTUAL RELEASE

     This Agreement and Mutual Release (the “Agreement”) is entered into on May 11, 2003 by and between Sina Corporation (the “Company”), and Daniel Daolin Mao (“Employee”).

RECITALS

     Employee has been employed by the Company and has entered into a Confidential Information and Invention Assignment Agreement (the “Confidentiality Agreement”), among other agreements, with the Company. The Company and Employee have mutually agreed to terminate their employment relationship and to release each other from any claims arising from or related to the employment relationship as described below.

AGREEMENT

     In consideration of the mutual release of claims and promises set forth below and other obligations under this Agreement, the parties agree as follows:

     1.     Termination. The Company and Employee acknowledge and agree that his employment relationship with the Company will terminate on May 11, 2003 (the “Termination Date”). The Company and Employee also acknowledge and agree that commencing from the Termination Date, Employee will no longer serve as the Company’s Chief Executive Officer and will resign from all positions held in the Company’s subsidiaries and affiliated companies listed in the Exhibit A attached hereto (all positions mentioned above collectively referred to as the “Positions” and all companies listed in the Exhibit A collectively referred to as the “SINA Entities”). The Company and Employee also acknowledge and agree that Employee will remain as a Director on the Board of Directors of the Company until the Company’s Annual Meeting of Shareholders held in year 2003 (“2003 Annual Meeting”); the Company may recommend, at its sole discretion, Employee or any other persons as the nominee for election of Director at 2003 Annual Meeting to fill such position or reduce the size of the Board in accordance with the Articles of Association of the Company. Likewise, Employee may resign his position as a director at any time. If Employee is nominated and elected as a director at the 2003 Annual Meeting, he shall be compensated as an outside director beginning at such time. Employee shall deliver to the Company such documents as the Company may reasonably request which he has signed or is required to sign as an officer in the various Positions he held prior to the Termination Date. Employee shall also deliver duly executed termination letters for all Positions held by Employee and all other necessary documents to effect such terminations and change of the registrations of the Company and the SINA Entities.

     2.     Settlement Payment. In consideration for the release of claims set forth below and other obligations under this Agreement and in full satisfaction of the Company’s obligations to Employee under the terms of the Employment Agreement between Employee and the Company, dated June 1, 2002 (the “Employment Agreement”), the Company will provide

-1-

Employee with the following severance benefits, subject in each case to any applicable income and employment taxes (“Settlement Payment”): (i) the Company will pay Employee his current regular monthly base salary of $25,000 per month for the period between the Termination Date herein and May 31, 2005 (the “Severance Period”), which represents the end of the term of the Employment Agreement; such payments shall be made ratably over the Severance Period according to the Company’s standard payroll schedule; (ii) the Company will also pay Employee $70,000 on the Termination Date, which represents the full bonus payable under Section 4(c) of the Employment Agreement; (iii) on the Termination Date, the Company will pay Employee all accrued vacation, which the parties agree is twenty (20) days; (iv) the Company will reimburse Employee for any expenses he has reasonably incurred in connection with his services to the Company up to the Termination Date, excluding moving expenses, in accordance with the Company’s policies; (v) during the Severance Period, the Company will pay for the cost of health insurance benefits with the same coverage provided to Employee prior to the Termination Date (e.g. medical, dental, optical, mental health) and in all other respects significantly comparable to those in place immediately prior to the Termination Date; and (vi) any currently unvested stock options or shares of restricted stock held by Employee as of the date of Employee’s termination of employment shall continue to vest up to the end of the Severance Period, according to the vesting schedule set forth in any agreement between Employee and the Company governing the issuance to Employee of such securities, provided that any vested stock options or shares which have not been exercised or purchased by Employee by the end of the 30 day period following the end of the Severance Period shall terminate and be cancelled. For the avoidance of doubt, it is acknowledged and agreed that vested options currently held by Employee will not terminate until, and accordingly Employee can exercise them until, 30 days following the end of the Severance Period. Except as set forth in this Agreement, the Company and Employee agree that after payment of the Settlement Payment, neither one will owe any amount of money, shares or any other consideration to the other.

     3.     Outstanding Loans.

     (a)  On July 28, 1999, the Company provided a loan to Employee, pursuant to a full recourse promissory note, in the principal amount of $600,000 with an interest rate of 5.74% per annum. The entire principal amount of this loan, plus accrued interest is currently outstanding. Employee acknowledges his payment obligations under this loan and agrees to repay in full the outstanding principal and accrued interest owed under this loan in accordance with the terms and the conditions of the promissory note.

     (b)  Beijing SINA Information Technology Co., Ltd. (formerly known as Beijing Stone Rich Sight Information Technology Co., Ltd.), a subsidiary of the Company, provided Employee an interest-free loan of RMB 300,000 pursuant to a Debt Transfer and Assumption Agreement dated August 15, 2001 (the “Debt Transfer and Assumption Agreement). The entire principal amount of this loan is currently outstanding. Employee acknowledges his payment obligations under this loan and agrees to repay in full the outstanding principal and accrued interest owed under this loan in accordance with its terms and the conditions. Employee agrees to transfer all rights and obligations thereunder to a designee of the Company immediately following the Effective Date of this Agreement.

If there are any shares of any of the SINA Entities standing in Employee’s name in the books of such company, Employee agrees and undertakes to transfer his interest in such company to any person as designated by the Company. Employee shall deliver to the Company duly executed documents to effect such transfer and the change of the registrations, and such other documents as reasonably requested by the Company from time to time. Employee hereby warrants that he did not and will not pledge, sell, contract to sell, grant any option, or otherwise transfer or dispose of any shares of any of the SINA Entities standing in Employee’s name in the books of such company as of the Termination Date, except to the parties as designated by the Company.

Employee acknowledges and agrees that he has received or will receive on the Termination Date all salary, accrued vacation, commissions, bonuses, compensation or other such sums due to Employee other than the Settlement Payment to be paid after the Termination Date pursuant to Section 2 of this Agreement and other consideration set forth in this Agreement. In light of the payment by the Company of all wages due, or to become due to Employee, the parties further acknowledge and agree that California Labor Code Section 206.5 is not applicable to the Parties hereto. That section provides in pertinent part as follows:
