Re: Supplement to InterTrust Technologies Corporation Option Exchange Program.
    Please read this message in its entirety.

Dear InterTrust Employees:

We are sending this letter based on comments from the Securities and Exchange
Commission (the "SEC") received after filing the recent offer to exchange (the
"Offer") outstanding options granted under the InterTrust Technologies
Corporation 1995 Stock Plan, 1999 Equity Incentive Plan and 2000 Supplemental
Plan (together, the "Plans") with an exercise price of $5.00 or more (after
giving effect to InterTrust's two-for-one stock split on February 24, 2000) for
new options InterTrust will grant under the Plans. Attached to this letter you
will find financial information which supplements the information provided in
the Offer. In deciding whether to participate in (or to modify or rescind your
participation in) the Offer, please consider this supplemental financial
information in making your decision. Any terms that are not otherwise defined in
this letter shall have the meanings given to them in the Offer.

Additionally, we have attached a revised letter of transmittal (the "Letter of
Transmittal") which removes the language requiring employees to acknowledge that
they have "read" and "understood" the Offer. You will be required to properly
complete and return to us this revised Letter of Transmittal by the expiration
date of the Offer. We apologize for the inconvenience to those of you who had
already submitted the original Letter of Transmittal.

If you wish to tender your options for exchange, you must complete and sign the
Letter of Transmittal in accordance with its instructions, and mail or otherwise
deliver it and any other required documents to us by fax to (408) 855-0144 or by
email to jamster@intertrust.com or by post to InterTrust Technologies
