Units and the Base Price Per Share shall be proportionately adjusted as follows:

Stock, the Base Price Per Share in effect at the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend shall be reduced by multiplying such Base Price Per Share
by a fraction, the numerator of which shall be the number of Shares of Common
Stock outstanding at the close of business on the date fixed for such
determination and the denominator shall be the sum of such number of Shares and
the total number of Shares constituting such dividend or other distribution,
such reduction to become effective immediately after the opening of business on
the day following the date fixed for such determination;

                      (ii) In case outstanding Shares of Common Stock shall be
subdivided into a greater number of Shares of Common Stock, the Base Price Per
Share in effect at the opening of business on the day following the day upon
which such subdivision becomes effective shall be proportionately reduced, and,
conversely, in case outstanding Shares of Common Stock shall each be combined
into a smaller number of Shares of Common Stock, the Base Price Per Share in
effect at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately increased, such reduction
or increase, as the case may be, to become effective immediately after the
opening of business on the day following the day upon which such subdivision or
combination becomes effective;

                      (iii) Upon each adjustment of the Base Price Per Share
pursuant to this subparagraph (a), the number of Director Units held by the
Director immediately prior to such adjustment shall be adjusted to a number of
Director Units equal to the number of Director Units held by the Director
immediately prior to such adjustment multiplied by a fraction, the numerator of
which shall be the Base Price Per Share in effect immediately prior to such
adjustment and the denominator of which shall be

                                        3

the Base Price Per Share in effect immediately after such adjustment.

               (b) Except as expressly provided in subparagraph (a) above, the
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, for cash, property, labor or
services, upon direct sale, upon the exercise of rights or warrants to subscribe
therefor, or upon conversion of shares or other securities, and in any case
whether or not for fair value, shall not affect, and no adjustment by reason
thereof shall be made with respect to, the Director Units or Base Price Per
Share.

                The Consultant and the Company acknowledge and agree that there
                were 187,791 shares of the August Shares already vested as of
                the Separation Date and the vesting of the August Option shall
                accelerate such that 134,137 unvested shares of the August
                Shares shall become immediately vested as of the Effective Date.
                Accordingly, the Consultant shall be entitled to 321,928 shares

consultants of the Company and other SINA Entities following the Separation
Date.

        11. NO OTHER PAYMENTS DUE. The Consultant and the Company agree that all
salary, accrued vacation and other sums due from the SINA Entities to the
Consultant are considered fully paid if the benefits in favor of the Consultant
provided under this Agreement are fully delivered. By executing this Agreement,
the Consultant hereby acknowledges that, in light of the payment by the Company
and other SINA Entities of all wages due to the Consultant, California Labor
Code Section 206.5 is not applicable to the Parties hereto. That section
provided in pertinent part as follows:

                NO EMPLOYER SHALL REQUIRE THE EXECUTION OF ANY RELEASE OF ANY
                CLAIM OR RIGHT ON ACCOUNT OF WAGES DUE, OR TO BECOME DUE, OR
                MADE AS AN ADVANCE ON WAGES TO BE EARNED, UNLESS PAYMENT OF SUCH
                WAGES HAS BEEN MADE.

        12. CERTAIN BUSINESS COMBINATIONS. In the event it is determined by the
Board of Directors of the Company, upon consultation with Company management and
the Company's independent auditors, that the enforcement of any Section of this
Agreement, including, but not limited to, Section 7 hereof, would preclude
accounting for any proposed business combination of the Company involving a
Corporate Transaction as a pooling of interests, and the Board of Directors of
the Company otherwise desires to approve such a proposed business transaction
which requires as a condition to the closing of such transaction that it be
accounted for as a

                                      -4-

pooling of interests, then any such Section of this Agreement shall be null and
void. However, under such circumstance, the Company is obligated to make
appropriate arrangement to ensure that all benefits intended to be provided to
the Consultant under this Agreement shall be otherwise fully paid as scheduled.

        13. RELEASE OF CLAIMS. The Consultant and the Company including all
other SINA Entities, on behalf of themselves, and their respective officers,
directors, consultants, investors, stockholders, administrators, predecessor and
successor corporations and assigns, hereby fully and forever release each other
and their respective officers, directors, consultants, investors, stockholders,
administrators, predecessor and successor corporations and assigns from claims,
demands, obligations, and causes of action of any nature whatsoever, whether in
tort (including, without limitation, acts of active negligence), contract or any
other theory of recovery in law, or equity, whether or not wrongful, whether for
compensatory or punitive damages, equitable relief or otherwise, and whether now
known or unknown, suspected or unsuspected, by reason of any matter or thing
arising from any cause relating to or arising from the Consultant's employment
or directorship relationship with any SINA Entitles or the termination of any of
such relationship or the Positions prior to the date of execution and delivery
of this Agreement.

        The Company and the Consultant agree that the release set forth in this
Section 13 shall be and remain in effect in all respects as a complete general
release as to the matters released. This release does not extend to the
obligations of the Consultant and Company under this Agreement.

        14. CIVIL CODE SECTION 1542. The Parties represent that they are not
aware of any claim(s) exist or suspect to exist up until and including the
Effective Date of this Agreement by either of them other than the claims that
are released by this Agreement. The Consultant and the Company acknowledge that
they are familiar with the provisions of California Civil Code Section 1542,
which provides as follows:

                        A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
                CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE
                TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE
                MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

        The Consultant and the Company, being aware of such code section, agree
to waive any rights they may have thereunder, as well as under any other stature
or common law principles of similar effect.

        15. CONFIDENTIALITY. Except as required to file with the US Securities
Exchange Commission in the Company's quarterly and annual report or required by
other appropriate government authorities, the Parties each agree to use their
best efforts to maintain in confidence the existence of this Agreement, the
contents and terms of this Agreement (excluding Section 3 of this Agreement),
and the consideration for this Agreement (hereinafter collectively referred to

                                      -5-

as "SEPARATION INFORMATION"). Unless otherwise provided herein, each Party
hereto agrees to take every reasonable precaution to prevent disclosure of any
Separation Information to third parties, and each agrees that there will be no
publicity, directly or indirectly, concerning any Separation Information. The
Parties agree to take every precaution to disclose Separation Information only
to those consultants, officers, directors, attorneys, accountants, governmental
entities, and family members who have a reasonable need to know of such
Separation Information.

        16. NONDISCLOSURE OF CONFIDENTIAL AND PROPRIETARY INFORMATION. The
Consultant shall continue to maintain the confidentiality of all confidential

and the Deed dated September 12, 1997 between the Consultant and the Company
attached hereto as Exhibit B. The Consultant agrees that at all times hereafter,
the Consultant shall not intentionally divulge, furnish or make available to any
party any of the trade secrets, patent applications, price decisions or
determinations, inventions, customers, proprietary information or other
intellectual property rights of the Company, until after such time as such
information has become publicly known otherwise than by act or collusion of the
Consultant.

        17. NON-COMPETITION AND NON-SOLICITATION COVENANT. In consideration for
the receipt of the benefits provided pursuant to this Agreement, the Consultant
hereby agrees that he shall not do any of the following without the prior

months following the Effective Date:

                (a) SOLICIT BUSINESS. Solicit or influence or attempt to
        influence any client, customer, or other person, to direct his or its

        business of the SINA Entities or solicit any licensor to the SINA
        Entities or licensee of the SINA Entities' products, in each case, that
        are known to the Consultant, with respect to any business, products or
        services that are competitive to the products or services offered by the
        SINA Entities or under development as of the Effective Date.

                (b) SOLICIT PERSONNEL. Solicit, induce, encourage or influence
        or attempt to solicit, induce, encourage or influence, any person

        relationship with the SINA Entitles or become an consultant, consultant
        or service provider of any competitor of the SINA Entitles, whether for
        the Consultant or for any other person or entity. The Consultant agrees
        to inform the Company immediately after consultant decides to hire any
        SINA Staff who voluntarily leaves SINA.

                (c) NON-COMPETITION. Engage, own beneficial interest, or be

        18. NON-DISPARAGEMENT. Each Party agrees to refrain from any
disparagement, criticism, defamation, slander of the other, or tortious
interference with the contracts and relationships of the other. In response to
any requests for references, the Company shall respond in a writing containing
only the dates of the Consultant's employment, and, upon written request by the
Consultant, confirmation of the Consultant's salary as of the Separation Date.

        19. NO REPRESENTATIONS. Each Party represents that it has carefully read
and understands the scope and effect of the provisions of this Agreement.
Neither Party has relied upon any representations or statements made by the
other Party which are not specifically set forth in this Agreement.

        20. COSTS. The Parties shall each bear their own costs, attorneys' fees
and other fees incurred in connection with this Agreement.

        21. SEVERABILITY. In the event that any provision hereof becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement shall continue in full force and effect without said
provision. However, under such circumstance, the Company is obligated to make
appropriate arrangement to ensure that all benefits intended to be provided to
the Consultant under this Agreement shall be otherwise fully paid as scheduled.
The Consultant expressly agrees that the character, duration and scope of the
provisions set forth in Section 17 of this Agreement are reasonable in light of
the circumstances as they exist on the date hereof. If any court of competent
jurisdiction determines that any covenant or provision contained in this
Agreement, including Section 17, or any part thereof, is invalid or
unenforceable because of the duration of such provision or the area covered
thereby, such court shall have the power to reduce the duration or area of such
provision and, in its reduced form, such provision shall then be enforceable and
shall be enforced.

        22. ENTIRE AGREEMENT. Except for obligations which continue after
termination of the Consultant's employment relationship with the Company
pursuant to the Exhibit A and Exhibit B of this Agreement, this Agreement
represents the entire agreement and understanding between the Company and the
Consultant concerning the termination of the Consultant's employment
relationship and directorship with the Company and other SINA Entities, and
supersedes and replaces any and all prior agreements and understandings
concerning the Consultant's relationship with the Company and the Consultant's
compensation by the Company.

        23. NO ORAL MODIFICATION. This Agreement may only be amended in a
writing signed by the Consultant and an officer of the Company.

        24. GOVERNING LAW. This Agreement shall be governed by the laws of the
State of California, without reference to its conflicts of law provisions.

constitute an effective, binding agreement on the part of each of the
undersigned.

        26. ARBITRATION. Any dispute or claim arising out of or in connection
with this Agreement will be finally settled by binding arbitration in the county
of San Mateo, California in accordance with the rules of the American
Arbitration Association by one arbitrator appointed in accordance with said
rules. The arbitrator shall apply California law, without reference to rules of
conflicts of law or rules of statutory arbitration, to the resolution of any
dispute. Judgment on enforcing the award rendered by the arbitrator may be
entered by any court having jurisdiction thereof. Notwithstanding the foregoing,
the Parties may apply to any court of competent jurisdiction for preliminary or
interim equitable relief, or to compel arbitration in accordance with this
paragraph, without breach of this arbitration provision. This Section 26 shall
not apply to the Section 16 of this Agreement. The Parties hereby waive any
rights they may have to trial by jury in regard to arbitrable claims.

        27. BREACH OF THE AGREEMENT. The Consultant and the Company acknowledge
that upon breach of this Agreement, the non-breaching Party would sustain
irreparable harm from such breach, and, therefore, the breaching Party agrees
that in addition to any other remedies which the non-breaching Party may have
under this Agreement or otherwise, the non-breaching Party shall be entitled to
obtain equitable relief, including specific performance and injunctions,
restraining the breaching Party from committing or continuing any such violation
of the Agreement. The Consultant acknowledges and agrees that upon the
Consultant's material breach of the Agreement, in addition to any other remedies
the Company may have under this Agreement or otherwise, the Company's
obligations to provide benefits including the title "Honorary Chief SINA" to the
Consultant as described in this Agreement shall immediately terminate. The
Company acknowledges and agrees that upon the Company's delay in making payments
to the Consultant provided under this Agreement, in addition to any other
remedies the Company may have under this Agreement or otherwise, the Company
shall be liable to pay a penalty of 2% interests of the amount outstanding for
each month's delay until the full amount is paid.

        28. AUTHORITY. The Company represents and warrants that the undersigned
has the authority to act on behalf of the Company and SINA Subsidiaries and to
bind the Company and SINA Subsidiaries and all who may claim through them to the
terms and conditions of this Agreement. The Consultant represents and warrants
that he has the capacity to act on his own behalf and on behalf of all who might
claim through him to bind them to the terms and conditions of this Agreement.
Each Party warrants and represents that there are no liens or claims of lien or
assignments in law or equity or otherwise of or against any of the claims or
causes of action released herein.

        29. SUCCESSOR AND ASSIGNS. This Agreement and all rights hereunder are
