CONVERTIBLE PROMISSORY NOTE

$1,500,000.00  September 29, 2004

FOR VALUE RECEIVED, the undersigned, CHINA MOBILESOFT LTD., a Bermuda corporation (“Borrower”), hereby promises to pay to PALMSOURCE, INC., a Delaware corporation (“Lender”), prior to or on May 25, 2005 (the “Maturity Date”), subject to acceleration or conversion as set forth herein, the aggregate principal amount of ONE MILLION FIVE HUNDRED THOUSAND DOLLARS ($1,500,000.00), such amount, together with the amount of any interest that has accrued and been added thereto in accordance with the terms of this Convertible Promissory Note (the “Note”), being referred to herein as the “Principal Amount.” The entire outstanding Principal Amount and all accrued but unpaid interest represented by this Note to date shall be repaid in full by Borrower on the Maturity Date, unless this Note is earlier accelerated or converted in accordance with the terms hereof.


1.Interest. Interest on the outstanding Principal Amount shall accrue daily at the rate of 6% per annum, compounded quarterly, from the date on which the Principal Amount has first been loaned to Borrower, through and including the date on which such Principal Amount is paid in full, or this Note is converted in accordance with Section 3 hereof. All computations of interest payable under this Note shall be made on the basis of the actual number of days elapsed divided by 360. Notwithstanding the provisions of this Note, if the rate of interest payable hereunder is limited by law, the rate payable hereunder shall be the lesser of: (a) the rate set forth in this Note and (b) the maximum rate permitted by law. If, however, interest is accrued or paid hereunder in excess of the maximum rate of interest permitted by law, any interest so accrued or paid which exceeds such maximum rate shall automatically be considered a payment of principal and shall automatically be applied in reduction of principal due on this Note to the extent of such excess.

2.Payment. All payments of interest and principal hereunder shall be made in lawful money of the United States of America by wire transfer to such account as Lender may designate by ten (10) days advance written notice to Borrower or, if no such account has been designated, at the business address of Lender. All payments hereunder shall be applied first to any unpaid accrued interest, second to payment of all, if any, other amounts except principal due under or in respect of this Note, and third to repayment of the unpaid Principal Amount.

3.Conversion. This Note shall be convertible at Lender’s option as follows:

 (a)At any time during the occurrence and continuation of an Event of Default, Lender may convert this Note into capital stock of Borrower by providing Borrower with notice that Lender wishes to convert this Note (the “Conversion Notice”). Upon the date on which the Conversion Notice is received by the Borrower (following proper delivery of such Conversion Notice by Lender in accordance with Section 14 of this Note), or such later date as set forth therein (the “Conversion Date), this Note shall be converted into that number of shares of common stock of Borrower, par value $0.01 (the “Conversion Shares”) as shall be equal to the quotient, rounded upward to the nearest whole number, of (x) the sum of the outstanding Principal Amount and all accrued but unpaid interest represented by this Note as of the date of conversion, divided by (y) $0.80 (adjusted for stock splits, stock dividends, combinations, recapitalizations or the like).

 (b)Lender shall be deemed to be the holder of the Conversion Shares as of the Conversion Date. No provision of this Section 3 shall limit any of Borrower’s obligations or Lender’s rights under this Note (including, without limitation, the restrictions on Prohibited Activity set forth herein). As soon as practicable after Lender surrenders this Note to Borrower for conversion into Conversion Shares, Borrower shall issue and deliver to Lender a certificate representing the Conversion Shares.

4.Default and Acceleration. At Lender’s option, the outstanding Principal Amount and all accrued but unpaid interest represented by this Note will become immediately due and payable upon written notice of acceleration given by Lender to Borrower following the occurrence of any of the following events (each an “Event of Default”):

 (a)Nonpayment. Borrower shall fail to pay any portion of the Principal Amount, any interest on this Note or any other sum due hereunder, on the date on which such amount shall become due and payable, whether at the stated date of maturity or at any accelerated date of maturity or at any other date fixed for payment.

 (b)Covenants. Borrower shall (i) fail to perform in any material respect any of the covenants or agreements in Sections 7(a), 7(f) or 7(g) or Section 8(c), (d), (e), (g), (h) or (m) hereof, or (ii) fail to perform in any material respect any of the other covenants and agreements set forth herein (other than those specified elsewhere in this Section 4) and not cure such failure within ten (10) days after notice thereof.

12.Waiver of Presentment, Etc. Borrower hereby, to the fullest extent permitted by applicable law, waives presentment, demand, notice, protest and all other demands and notices in connection with delivery, acceptance, performance, default, acceleration or enforcement of or under this Note.

13.Amendment. This Note may not be amended or modified except in a writing signed by both parties.

14.Notices. Any notice, consent, election or other communication required or permitted to be given hereunder shall be in writing and shall be deemed duly given and received when delivered personally, when transmitted by facsimile with receipt acknowledged by the addressee, three days after being deposited as first class mail with the United States Postal Service, or one day after being deposited for next-day delivery with Federal Express or other nationally recognized overnight delivery service, all charges or first class postage prepaid.

15.Waiver. Except as expressly provided herein, no waiver of any provision of this Note shall be binding unless executed in writing by the party making the waiver. The failure of Lender to exercise any of its rights, remedies, powers or privileges hereunder in any instance will not constitute a waiver thereof, or of any other right or remedy, and no single or partial exercise of any right or remedy shall preclude any other or further exercise thereof or of any other right or remedy. No waiver of any provision of this Note shall be deemed to, or shall, operate as a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver.

21.Severability. If one or more of the provisions of this Note should for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provisions of this Note, and this Note shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein.

22.Confidentiality. Each of Lender and Borrower shall, and shall cause its respective affiliates and representatives to, keep all information relating to this Note and any Transaction confidential in accordance with the terms of the Agreement between Lender and Borrower dated August 10, 2004, except as otherwise provided in this paragraph.

- 15 -


determines in its sole discretion that public disclosure of information relating to this Note or any Transaction is required by law or applicable regulation or the requirements of a regulatory agency, stock exchange or over the counter market on which a party’s shares are listed for trading (“Required Disclosure”), such party shall provide the other party with as much prior written notice (including the language, form and content of the Required Disclosure) and an opportunity for consultation as is reasonably practicable under the circumstances of any intended Required Disclosure, it being understood that nothing herein shall prevent the disclosing party from making Required Disclosure. Lender and Borrower further agree that the language, form and content of any public disclosure of information relating to this Note or any Transaction (whether through a press release, public filing (which filing a party determines to be voluntary) or report, public statement or otherwise) that is not a Required Disclosure shall be mutually agreed in advance by the parties, which agreement shall not be unreasonably withheld.
