Republic of China (including those resulting from cancellation or reclamation of
tax benefits of any kind relating to the Company) arising from the grant,
issuance, vesting, exercise or sale of stock options held by you under the Stock
Option Agreements. At the request of the Company, you further agree to pledge,
to the Company on such terms and pursuant to written agreement(s), the form and
substance of which shall be satisfactory to the Company, any and all stock

this Agreement shall be deemed to be a waiver of any other provision.

Agreement in connection with a business combination (whether by merger, sale of
assets or otherwise) with another entity. This Agreement shall be binding upon
and inure to the benefit of the Company, and its successors, and you, your
heirs, executors, administrators and legal representatives.

                                LOCK-UP AGREEMENT

      From the date of the Agreement until January 3, 2007, you agree that you
will not, and will not announce or otherwise disclose to any third party your
intention or make any application or filing with the U.S. Securities and
Exchange Commission or any other applicable regulatory authority to, directly or
indirectly:

      (i) offer for sale, pledge, encumber, sell, contract to sell, sell any
option or contract to purchase, purchase any option or contract to sell, grant
any option, right or warrant to purchase, lend, or otherwise transfer or dispose
of (or enter into any transaction or device which is designed to, or could
reasonably be expected to, result in the disposition by any person at any time
in the future of), directly or indirectly, (A) ADSs, (B) Ordinary Shares or
securities convertible into or exercisable or exchangeable for Ordinary Shares,
(C) securities of the same class as the ADSs or Ordinary Shares or (D) other
instruments representing interests in securities of the same class as ADSs or
Ordinary Shares or

      (ii) sell, grant or enter into any option, right, warrant, swap or other
arrangement with respect to, or which transfers to another, in whole or in part,
of the economic consequences of ownership of ADSs or Ordinary Shares,

            whether any such transaction described in clause (i) or (ii) above
is to be settled by delivery of ADSs, Ordinary Shares or such other securities,
in cash or otherwise. The forgoing shall not, however, restrict or prohibit you
from effecting any transaction or series of transactions described above
involving, in the aggregate: (A) the sale or other disposition of 150,000 ADSs
that you have acquired and beneficially own as of the date of this Agreement;
and (B) in addition, during any 30-day period from and after the date of the
Agreement, the sale or other disposition of up to 22,811 ADSs, including one or
more transactions involving options, rights, warrants, swaps or other
arrangements with respect to the economic consequences of ownership of not more
than 22,811 ADSs or an equivalent number of Ordinary Shares (the "ALLOWED 30-DAY
DISPOSITION"). Notwithstanding the foregoing, if you do not sell or otherwise
enter into any other arrangement as described above with respect to the entire
Allowed 30-day Disposition in any given 30-day period pursuant to subclause (B)
above, the Allowed 30-day Disposition for the next 30-day period shall include
the amount specified in subclause (B), plus the amount of the unused Allowed
30-Day Disposition for the prior 30-day period. Such unsold Allowed 30-day
Dispositions shall accumulate in each 30-day period from the date hereof,
provided that you may not in any event sell or otherwise enter into any other
arrangement as described above with respect to more than 45,622 ADSs in any
60-day period. All sales or other transactions consummated pursuant to this
paragraph shall be subject to Rule 144 of the Securities Act of 1933, as amended
(including without limitation the volume restrictions thereunder).

      Any ADSs or Ordinary Shares received upon exercise of options granted to
the undersigned will also be subject to this Agreement. Any ADSs or Ordinary
Shares acquired by the undersigned in the open market will also be subject to
this Agreement.

      In the event that you violate, breach or fail to abide by the terms of
this lock-up agreement or any term of the Agreement, you agree that you will be
prohibited from disposing of any securities of Linktone in any transaction or
series of transactions described above, and that the exception described in
paragraph 4 above will not apply, until such time as a settlement has been
reached between you and Linktone, or a final judgment by a court with valid
jurisdiction has been issued, regarding any such violation, breach or failure to
abide to the terms of this lock-up agreement.

      In furtherance of the foregoing, the Company, its transfer agent and
registrar and the depositary for the ADSs are hereby authorized to decline to
make any transfer of ADSs or Ordinary Shares or issue any stop orders if such
transfer would constitute a violation or breach of this Agreement.
