reason with or without cause upon thirty (30) days' advance written notice. The
Company shall have the option, in its complete discretion, to terminate the
Executive at any time prior to the end of such notice period, provided the

actually worked, plus an amount equal to the Base Salary and Annual Benefits the
Executive would have received through the balance of the above notice period;
thereafter, all of the Company's obligations under this Agreement shall cease.

months payment of the annual Base Salary and Annual Benefits. In addition, the

options according to the Executive's Stock Option Agreement for a period of 3
months from the date of termination. The Company may discipline or demote the

         4.2      EXCLUSIVE TERMINATION PROVISIONS. This Article 4 is intended
to be the complete and exclusive statement regarding the circumstances under
which the Executive's employment may be terminated. It supersedes any prior
agreement or representation. If any term of this Article 4 conflicts with any
practice or policy of the Company, now or in the future, the terms of this
Article 4 will control. The Executive's status as an at-will employee may not be
changed except by written agreement signed by the Company's Chief Executive
Officer or his or her representative specially authorized in writing to fulfill
this obligation under this Agreement.

relocate to a facility or location more than one hundred (100) miles from the
Company's current location, or (2) there is a material adverse change in
Executive's position causing such position to be of less stature or of less
responsibility than Chief Technology Officer; and (B) within the ninety (90) day
period immediately following such event Executive elects to terminate his
employment voluntarily.

         5.1      RETURN OF PROPERTY. Executive agrees that all property
(including without limitation all equipment, tangible proprietary information,
documents, records, notes, contracts and computer-generated materials) furnished

belongs to the Company and shall be promptly returned to the Company upon

         5.2      RESIGNATION AND COMPENSATION. Following any termination of
employment, Executive shall cooperate with the Company in the winding up of
pending work on behalf of the Company and the orderly transfer of work to other
employees. Executive shall also cooperate with the Company in the defense of any
action brought by any third party against the Company that relates to
Executive's employment by the Company.

                                                                               4

                  PROPRIETARY RIGHTS AND INFORMATION AGREEMENT

                  In consideration of my employment by Linktone Ltd. (the
"Company"), I hereby agree to the following restrictions and obligations placed
on my use and development of information, technology, ideas, inventions and
other materials:

1.       PROPRIETARY INFORMATION

         a.       RESTRICTIONS ON PROPRIETARY INFORMATION. I agree that, during
my employment and at all times thereafter, I will hold the Proprietary
Information of the Company in strict confidence and will neither use the
information for the benefit of myself or any other third party nor disclose it
to anyone, except to the extent necessary to carry out my responsibilities as an
employee of the Company or as specifically authorized in writing by a duly
authorized officer of the Company other than me. I understand that "Proprietary
Information" means all information pertaining in any manner to the business of
the Company or its affiliates, consultants, customers, business associates or
members, unless (i) the information is or becomes generally known to the public
through lawful means and through no fault of mine; (ii) the information was part
of my general knowledge prior to the initial disclosure of the information by
the Company or any person under a duty of confidentiality; or (iii) the
information is disclosed to me without restriction by a third party who
rightfully possesses the information and is under no duty of confidentiality.
This definition of "Proprietary Information" includes but is not limited to any
and all (a) technical or non-technical information, know-how, computer software
(whether in source code or object code form), programs, tools, data, research,
designs, drawings, diagrams, plans, specifications, trade secrets, inventions,
concepts, structures, improvements, products, patents pending, prototypes,
processes, formulas, algorithms, methods, techniques, hardware, devices,
schematics, works in process, systems, technologies or applications; (b)
financial and other information about costs, profits, markets, sales and pricing
structures, customers, subscribers, members, and bids; (c) plans, forecasts and
strategies for business, marketing, future development and new product concepts;
and (d) employee personnel files and information about employee compensation and
benefits; in any form and whether or not labeled or identified as confidential
or proprietary. I agree that I will have the burden of proving the applicability
of any of the foregoing exceptions.

         b.       LOCATION AND REPRODUCTION. I agree to maintain at my work
station and/or any other place under my control only such Proprietary
Information as I have a current "need to know." I agree to return to the
appropriate person or location or otherwise properly dispose of Proprietary
Information once that need to know no longer

<PAGE>

                                                                       EXHIBIT A

exists. I also agree that I will make copies and otherwise reproduce Proprietary
Information solely to the extent necessary to carry out my responsibilities as
an employee of the Company or as specifically authorized by a duly authorized
officer of the Company other than me.

         c.       PRIOR ACTIONS AND KNOWLEDGE. Except as disclosed on Schedule A
to this Agreement, I have no knowledge about the Company's business or
Proprietary Information, other than information I have learned from the Company
in the course of being hired and employed.

         d.       THIRD-PARTY INFORMATION. I recognize that the Company has
received and will receive confidential or proprietary information from third
parties. I will hold all such information in the strictest confidence and will
not use the information or disclose it to anyone (except as necessary in
carrying out my work for the Company consistent with the Company's agreement
with such third party).

         e.       INTERFERENCE WITH BUSINESS. I acknowledge that because of my
position in the Company, I will have access to the Company's confidential
information and trade secrets. I agree that during my employment with the
Company and for a period of 2 years after termination of my employment with the
Company, I shall not directly or indirectly (i) divert or attempt to divert from
the Company (or any affiliate) any business of any kind, including without
limitation the solicitation of or interference with any of its customers,
clients, members, business partners or suppliers or (ii) solicit, induce,
recruit or encourage any person employed by the Company to terminate his or her
employment.

         f.       NONCOMPETITION. I acknowledge that the Company's relationships
with its customers, clients, vendors, employees and other entities are valuable
business assets, and that there is a substantial likelihood that if I directly
compete with the Company, it would result in the unauthorized use or disclosure
of Proprietary Information or interfere with the Company's relationship with its
customers, clients, vendors, employees and other entities, which use or
disclosure of Proprietary Information would be extremely difficult to detect or
prove. Therefore, and in consideration for my employment with the Company, I
agree that during the period of my employment with the Company and for a period
of 1 year after termination of my employment with Company, I shall not, directly
or indirectly engage or participate in the development, marketing or
distribution of wireless media, entertainment and communication services in
China in three major categories: personalized media, games and entertainment,
and information and communication.

2.       INNOVATIONS

         a.       INNOVATIONS. "Innovations" collectively means any and all
ideas, concepts, inventions, discoveries, developments, software, content,
textual or artistic works, video, graphics, sound recordings, know-how,
structures, designs, formulas, algorithms, methods, products, processes, systems
and technologies in any stage of development that are conceived, created,
developed or reduced to practice by me alone or with others; any and all
patents, patents pending, copyrights, moral rights, trademarks and any other
intellectual property rights therein; and any and all improvements,
modifications, derivative works from, other rights in and claims related to any
of the foregoing under the laws of any jurisdiction; except Innovations excluded
in Schedule A.

         b.       OWNERSHIP OF INNOVATIONS. I hereby agree and acknowledge that
all Innovations shall be deemed to be "works made for hire" belonging to
Company. To the extent that any such Innovations, under applicable law, may not
be considered work made for hire by me for Company, or to the extent that such
Innovation is a patentable invention under Title 35 of the United States Code, I
agree to assign, and upon creation automatically assign, and transfer to the
Company, without further consideration, my entire right, title and interest
(throughout the United States and in all other countries or jurisdictions), free
and clear of all liens and encumbrances, in and to all Innovations, including
all intellectual property rights in such Innovations, as well as any extensions
and renewals thereof. Such assignment and transfer to the Company shall be
continuous during my employment as of the relevant time of development of each
such Innovation. The Company may, in its sole discretion, agree to provide
consideration for certain Innovations through a written agreement between the
Company and the undersigned which specifically provides for such consideration;
in all other cases, no consideration shall be paid. The Innovations shall be the
sole property of the Company, whether or not copyrightable or patentable or in a
commercial stage of development.

         c.       MORAL RIGHTS. To the extent allowed by law, this assignment of
Innovations includes all rights of paternity, integrity, disclosure and
withdrawal and any other rights that may be known as or referred to as "moral
rights," "artist's rights," or the like (collectively "Moral Rights"). To the
extent I retain any such Moral Rights under applicable law, I hereby ratify and
consent to any action that may be taken with respect to such Moral Rights by or
authorized by the Company and agree not to assert any Moral Rights with respect
thereto. I will confirm any such ratifications, consents and agreements from
time to time as requested by the Company.

         d.       LICENSE FOR OTHER INNOVATIONS. I agree not to incorporate into
any Company property any work or invention owned by me or in which I have an
interest without obtaining Company's prior written consent. If, after receiving
such consent, in the course of my employment with the Company, I incorporate
into Company property a work or invention owned by me or in which I have an
interest, I hereby grant to the Company a worldwide, nonexclusive, royalty-free,
irrevocable, perpetual, transferable and sublicenseable (through multiple tiers)
license to make, use, import, offer for sale, sell, copy, distribute, publicly
display, perform publicly and by means of a digital audio transmission such work
or invention as part of and in connection with the Company property.

         e.       ASSIST WITH REGISTRATION AND PROTECTION. In the event any
Innovation shall be deemed by the Company to be copyrightable, patentable or
otherwise registrable, I will assist the Company (at its expense) in every way
deemed necessary or desirable by Company to protect the Innovations throughout
the world, including without limitation, performing acts necessary for
obtaining, maintaining and enforcing patent or other applicable registrations
and vesting the Company, or any of its affiliates, with full title. Should the
Company be unable to secure my signature on any document necessary to apply for,
prosecute, obtain, or enforce any patent, copyright, or other right or
protection relating to any Innovation, due to my incapacity or any other cause,
I hereby irrevocably designate and appoint the Company and each of its duly
authorized officers and agents as my agent and attorney-in-fact to do all
lawfully permitted acts to further the prosecution, issuance, and enforcement of
patents, copyrights, or other rights or protection with the same force and
effect as if executed and delivered by me.

         f.       DISCLOSURE. I agree to maintain current and adequate written
records on the development of all Innovations, and to disclose promptly to the
Company all such Innovations and records. I further agree to disclose promptly
to the Company any idea that I do not believe to be an Innovation, but which is
conceived, developed, or reduced to practice by me (alone or with others) while
I am employed by the Company, I will disclose the idea, along with all
information and records pertaining to the idea, and the Company will examine the
disclosure in confidence to determine if in fact it is an Innovation subject to
this Agreement.

3. FORMER OR CONFLICTING AGREEMENTS

         a.       FORMER AGREEMENTS. I represent and warrant that my performance
of the terms of this Agreement will not breach any agreement to keep in
confidence proprietary information acquired by me prior to my employment by the
Company. I

have listed in Schedule A all other agreements concerning proprietary
information or inventions to which I am a party and attached copies of any

contract between me and any other person or entity that is in conflict with this
Agreement or concerns proprietary information, inventions or assignment of
ideas.

         b.       PROHIBITION ON USE OF THIRD PARTY INFORMATION. I represent and
warrant and covenant that I will not disclose to the Company, or use, or induce
the Company to use, any proprietary information or trade secrets of others at
any time, including but not limited to any proprietary information or trade
secrets of any former employer, if any. I acknowledge and agree that any
violation of this provision shall be grounds for my immediate termination and
could subject me to substantial civil liabilities and criminal penalties. I
further specifically and expressly acknowledge that no officer or other employee
or representative of the Company has requested or instructed me to disclose or
use any such third party proprietary information or trade secrets.

4. TERMINATION

         a.       RETURN OF THE COMPANY'S PROPERTY. I agree to promptly return
to the Company upon termination of my employment all Proprietary Information,
including all tangible embodiments of such Proprietary Information in my
possession, and all personal property furnished to or prepared by me in the
course of or incident to my employment. Following my termination, I will not
retain any written or other tangible material containing any Proprietary
Information or information pertaining to any Innovation.

         b.       TERMINATION CERTIFICATE. In the event of the termination of my
employment, I agree, if requested by the Company, to sign and deliver the
Termination Certificate attached as Schedule B.

         c.       SUBSEQUENT EMPLOYERS. I agree that after the termination of my
employment with the Company, I will not enter into any agreement that conflicts
with my obligations under this Agreement and will inform any subsequent
employers of my obligations under this Agreement.

                  I recognize that nothing in this Agreement shall be construed
to imply that my employment is guaranteed for any period of time. Unless stated

reason or no reason, with or without cause.

6.       REMEDIES

                  I recognize that nothing in this Agreement is intended to
limit any remedy of the Company under any federal or state law concerning trade
secrets. I recognize that my violation of this Agreement could cause the Company
irreparable harm and agree that the Company shall have the right to apply to any
court of competent jurisdiction for an order restraining any breach or
threatened breach of this Agreement.

7.       ASSIGNMENT

                  I acknowledge and agree that my performance is personal
hereunder, and that I shall have no right to assign and shall not assign or
purport to assign any rights or obligations under this Agreement. This Agreement
may be assigned or transferred by the Company. Subject to the foregoing
restrictions on assignment, this Agreement shall inure to the benefit of the
Company and its affiliates, officers, directors, agents, successors and assigns;
and shall be binding on me and my heirs, devisees, spouses, agents, legal
representatives and successors.

8.       GOVERNING LAW AND ARBITRATION

                  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York without reference to conflicts
of law principles. Any dispute arising out of this Agreement that the Company
and I cannot settle amicably shall be resolved exclusively by arbitration before
one neutral arbitrator in the City of New York and administered by the American
Arbitration Association ("AAA") in accordance with its Employment Dispute
Arbitration Rules. The arbitrator shall be an attorney selected by mutual
agreement of the Company and me; however, if we cannot agree on the selection of
an arbitrator within fifteen (15) days following the delivery by either party to
the other of a demand for arbitration, the arbitrator shall be selected by or in
accordance with the Employment Dispute Arbitration Rules of the AAA.

9.       SEVERABILITY

                  If any provision of this Agreement, or application thereof to
any person, place, or circumstance, shall be held by a court of competent
jurisdiction to be

 unenforceable, such provision shall be enforced to the
greatest extent permitted by law and the remainder of this Agreement shall
remain in full force and effect.

10.      AMENDMENT; WAIVERS

                  This Agreement may not be amended or waived except by a
writing signed by me and by a duly authorized representative of the Company
other than me. Failure to exercise any right under this Agreement shall not
constitute a waiver of such right. Any waiver of any breach of this Agreement
shall not operate as a waiver of any subsequent breaches. All rights or remedies
specified for a party herein shall be cumulative and in addition to all other
rights and remedies of the party hereunder or under applicable law.

11.      INTERPRETATION

                  This Agreement shall be construed as a whole, according to its
fair meaning, and not in favor of or against any party. Sections and section
headings contained in this Agreement are for reference purposes only, and shall
not affect in any manner the meaning of interpretation of this Agreement.
Whenever the context requires, references to the singular shall include the

gender.

12.      ENTIRE AGREEMENT

         The terms of this Agreement are the final expression of my agreement
with respect to the subject matter hereof and may not be contradicted by
evidence of any prior or contemporaneous agreement. This Agreement shall
constitute the complete and exclusive statement of its terms. I acknowledge that
the Company has not made any other representations or warranties concerning the
subject matter of this Agreement. The termination of any employment or other
agreement between the Company and me shall not terminate this Agreement and each
and all of the terms and conditions hereof shall survive and remain in full

                              ARBITRATION AGREEMENT

         Linktone Ltd. (the "Company") and Employee hereby agree that, to the
fullest extent permitted by law, any and all claims or controversies between
them (or between Employee and any present or former officer, director, agent, or
employee of the Company or any parent, subsidiary, or other entity affiliated
with the Company) relating in any manner to the employment or the termination of
employment of Employee shall be resolved by final and binding arbitration.
Except as specifically provided herein, any arbitration proceeding shall be
conducted in accordance with the National Rules for the Resolution of Employment
Disputes of the American Arbitration Association ("the AAA Rules").

         Claims subject to arbitration shall include, without limitation:
contract claims, tort claims, claims relating to compensation and stock options,
as well as claims based on any federal, state, or local law, statute, or
regulation.

         A neutral and impartial arbitrator shall be chosen by mutual agreement
of the parties; however, if the parties are unable to agree upon an arbitrator
within a reasonable period of time, then a neutral and impartial arbitrator
shall be appointed in accordance with the arbitrator nomination and selection
procedure set forth in the AAA Rules. The arbitrator shall prepare a written
decision containing the essential findings and conclusions on which the award is
based so as to ensure meaningful judicial review of the decision. The arbitrator
shall apply the same substantive law, with the same statutes of limitations and
same remedies, that would apply if the claims were brought in a court of law.

         Either the Company or Employee may bring an action in court to compel
arbitration under this Agreement and to enforce an arbitration award. Otherwise,
neither party shall initiate or prosecute any lawsuit of claim in any way
related to any arbitrable claim. Nothing in this Agreement, however, precludes a
party from filing an administrative charge before an agency that has
jurisdiction over an arbitrable claim.

         All arbitration hearings under this Agreement shall be conducted in New
York, unless otherwise agreed by the parties. The arbitration provisions of this
Arbitration Agreement shall be governed by the Federal Arbitration Act. In all
other respects, this Arbitration Agreement shall be construed in accordance with
the laws of the State of New York, without reference to conflicts of law
principles.

         Each party shall pay its own costs and attorney's fees, unless a party
prevails on a statutory claim, and the statute provides that the prevailing
party is entitled to payment of its

                                                                               1

attorneys' fees. In that case, the arbitrator may award reasonable attorneys'
fees and costs to the prevailing party as provided by law.

         This Agreement does not alter Employee's at-will employment status.
Accordingly, Employee understands that the Company may terminate Employee's
employment, as well as discipline or demote Employee, at any time, with or
without prior notice, and with or without cause. The parties also understand
that Employee is free to leave the Company at any time and for any reason, with
or without cause and with or without advance notice.

         If any provision of this Agreement shall be held by a court or the
arbitrator to be invalid, unenforceable, or void, such provision shall be
enforced to the fullest extent permitted by law, and the remainder of this
Agreement shall remain in full force and effect. The parties' obligations under
this Agreement shall survive the termination of Employee's employment with the
Company and the expiration of this Agreement.

         The Company and Employee understand and agree that this Arbitration
Agreement contains a full and complete statement of any agreements and
understandings regarding resolution of disputes between the parties, and the
parties agree that this Arbitration Agreement supersedes all previous
agreements, whether written or oral, express or implied, relating to the
subjects covered in this agreement. The parties also agree that the terms of
this Arbitration Agreement cannot be revoked or modified except in a written
document signed by both Employee and an officer of the Company.

THE PARTIES ALSO UNDERSTAND AND AGREE THAT THIS AGREEMENT CONSTITUTES A WAIVER
OF THEIR RIGHT TO A TRIAL BY JURY OF ANY CLAIMS OR CONTROVERSIES COVERED BY THIS
AGREEMENT. THE PARTIES AGREE THAT NONE OF THOSE CLAIMS OR CONTROVERSIES SHALL BE
RESOLVED BY A JURY TRIAL.

THE PARTIES FURTHER ACKNOWLEDGE THAT THEY HAVE BEEN GIVEN THE OPPORTUNITY TO
DISCUSS THIS AGREEMENT WITH THEIR LEGAL COUNSEL AND HAVE AVAILED THEMSELVES OF
THAT OPPORTUNITY TO THE EXTENT THEY WISH TO DO SO.

                          AND TRADE SECRET INFORMATION

                  I understand that Linktone Ltd. (the "Company") has hired me
because of my job experience and qualifications, and not because it wants to
obtain trade secrets or other confidential or proprietary information from my
previous employers. Accordingly, I hereby certify that:

1.       I have returned all property provided to me, or obtained by me, from my
previous employers including, without limitation: all books, manuals, records,
models, drawings, reports, notes, contracts, customer lists and other lists,
blueprints, equipment, and other documents and materials. In addition, I did not
make or distribute any copies of the foregoing, except as authorized by my
previous employers.

2.       Listed on Schedule "A" are all non-disclosure, non-competition, and
non-solicitation agreements that I signed with previous employers. I have also
attached copies of all such agreements in my possession. To the best of my
knowledge, there are no other agreements between me and any other person or
entity concerning non-disclosure of proprietary information, non-competition, or
non-solicitation. I have reviewed the agreements listed on Schedule "A," and I
have complied with and will continue to comply with all of the lawful terms of
these agreements, including the preservation as confidential of all trade secret
and confidential information pertaining to my previous employers.

3.       My performance of my job duties for the Company will not breach any
agreement to keep in confidence confidential, proprietary, and trade secret
information that I may have acquired during my previous employment.

4.       During my employment with the Company, I will not disclose to the
Company any confidential, proprietary, or trade secret information of any of my
previous employers; I will not bring such information to the Company's
attention; and I will not use such information in my own employment by the
Company.
