         FOR VALUE RECEIVED, LANGUAGEWARE.NET (Company) LTD., an Israeli
corporation (hereinafter called the "Borrower" or "Company") hereby promises to
pay to the order Technology Fund II Pte Ltd., a company organized under the laws
of Singapore (the "Lender") the sum of THREE MILLION and no/100 dollars
($3,000,000.00) or so much thereof as may be advanced pursuant to paragraph 1 of
this Promissory Note ("Note"), on March 22, 2001 (the "Maturity Date"), and to
pay interest on the unpaid principal balance hereof at the prime rate of
interest as determined by the Wall Street Journal on the date hereof (the "Issue
Date") plus two hundred (200) basis points until the same becomes due and
payable whether at maturity or upon acceleration or otherwise. Interest on any
outstanding principal balance shall commence accruing on the Issue Date and, to
the extent not converted in accordance with the provisions of paragraph 3 below,
shall be payable on the Maturity Date. All payments of interest (to the extent
not converted in accordance with the terms hereof) shall be made in lawful money
of the United States of America. All payments shall be made at such address as
the Lender shall hereafter give to the Borrower by written notice made in
accordance with the provisions of this Note.

         1. Disbursements. Disbursements of principal shall be made from time to
time as requested by the Borrower. Borrower shall give Lender written notice of
any requested disbursements under this Note ("Disbursement Request"). Such
Disbursement Request shall include the amount of the requested disbursement, the
required date of receipt of the disbursement (which shall not be less than three
(3) business days from the date of the Disbursement Request) and wire transfer
instructions for receipt of such disbursement. Lender shall not be required to
disburse more than $500,000 per month unless otherwise agreed to by Lender.
Borrower shall have no obligation to request disbursement of any principal
hereunder.

         Upon determination by Lender that Borrower has met all requirements
under this Agreement, Lender shall disburse to the Borrower the amount set forth
in the Disbursement Request via wire transfer of immediately available funds
within the time set forth in the applicable Disbursement Request.

         2. Prepayment Borrower shall have no right to prepay the outstanding
principal on this Note unless such prepayment is approved by Lender in its
absolute and sole discretion.

         3. Conversion. At any time after the Issue Date, if the principal
amount of this Note has not been paid in full, Lender shall have the right to
convert all or any portion of the outstanding principal amount of this Note and



   2


any accrued but unpaid interest on this Note into ordinary shares of the
Borrower, par value NIS 0.01 ("Common Stock"). Lender may exercise its
conversion right by delivering to the Borrower a written notice stating that
Lender elects to convert into Common Stock all or a portion of the principal of
and interest on the Note as provided herein. Conversion shall be effective as of
the close of business on the date of delivery of such notice. As promptly as
practicable thereafter, the Borrower shall issue and deliver to Lender a
certificate for the shares of Common Stock issuable upon such conversion. Any
person in whose name the certificate for Common Stock is to be issued shall be
considered to have become a Lender of record of such Common Stock as of the
close of business on the date of the conversion ("Conversion Date"). The
Borrower shall not be required to issue fractional shares of Common Stock on the
conversion of the Note. If any fraction of a share would be issuable on the
conversion of the Note, such fractional share shall be disregarded and the
number of shares of Common Stock issuable upon conversion shall be the next
higher whole number of shares.

         4. Conversion Price. The number of shares of Common Stock issuable upon
conversion of the Note pursuant to paragraph 3 hereof shall be the number of
shares equal in value to the amount of the principal and interest to be
converted. The per share value of the Common Stock ("Conversion Price") shall be
the lesser of (a) $0.20; or (b) the lowest price per share received by the
Borrower between the Issue Date and the Maturity Date from the sale of its
Common Stock in an aggregate amount of not less than $6,000,000 to third parties
not related to the Lender ("Next Financing").

         5. Warrants. Borrower will issue to Lender warrants to purchase a
number of shares of Common Stock equal to one hundred percent (100%) of the
number of shares issuable to Lender upon conversion of any outstanding principal
drawn by Borrower pursuant to paragraph 1 and any accrued but unpaid interest on
such principal converted by Lender hereunder. The exercise price of the warrants
shall be the lesser of (a) $0.20; or (b) the price per share received by the
Borrower in the Next Financing. Such warrants shall be issued upon request by
Lender, will be exercisable upon issuance and will expire December 31, 2001. The
warrants issuable hereunder for amounts of principal drawn by Borrower shall be
granted irrespective of whether such outstanding principal is converted, repaid
or prepaid. Warrants issuable hereunder for accrued but unpaid interest on any
principal drawn by Borrower shall only be issued upon conversion of such
interest by Lender.

         6. Merger or Acquisition. In the event of a merger or acquisition of
the Company or a sale of all or substantially all of the Company's assets on or
before the Maturity Date, Lender shall have the option of (i) converting the
outstanding principal and accrued but unpaid interest into Common Stock of the
Company at the lesser of (x) $0.20 per share or (y) or the per-share merger,
acquisition or sales price or (ii) having the outstanding principal and all
accrued but unpaid interest fully repaid upon the closing of the merger,
