                      InterTrust Technologies Corporation

                             Stock Option Agreement



Tax Treatment         This option is intended to be a nonstatutory option, as
                      provided in the Notice of Stock Option Grant.

Vesting               This option becomes exercisable in installments, as shown
                      in the Notice of Stock Option Grant. In addition, this
                      option becomes exercisable and vested in full if the
                      Company is subject to a "Change in Control" (as defined
                      below) while you are an employee, consultant or director
                      of the Company or a subsidiary of the Company, unless this
                      option remains outstanding following the "Change in
                      Control," or is assumed by the surviving corporation (or
                      parent thereof) or substituted with an option with
                      substantially the same terms by the surviving corporation
                      (or parent thereof). The determination of whether a
                      substituted option has substantially the same terms as
                      this option shall be made by the Compensation Committee
                      (the "Committee"), and its determination shall be final,
                      binding and conclusive.

                      No additional shares become exercisable after your service
                      as an employee, consultant or director of the Company or a
                      subsidiary of the Company has terminated for any reason.

Term                  This option expires in any event at the close of business
                      at Company headquarters on the day before the 10th
                      anniversary of the Date of Grant, as shown in the Notice
                      of Stock Option Grant. (It will expire earlier if your
                      service terminates, as described below.)

Regular Termination   If your service as an employee, consultant or director of
                      the Company or a subsidiary of the Company terminates for
                      any reason except death or disability, then this option
                      will expire at the close of business at Company
                      headquarters on the date three months after your
                      termination date. The Company determines when your service
                      terminates for this purpose.

Death                 If you die as an employee, consultant or director of the
                      Company or a subsidiary of the Company, then this option
                      will expire at the close of business at Company
                      headquarters on the date 12 months after the date of
                      death.

Disability            If your service as an employee, consultant or director of
                      the Company or a subsidiary of the Company terminates
                      because of your disability, then this option will expire
                      at the close of business at Company headquarters on the

                                       2


                      date six months after your termination date.

                      For all purposes under this Agreement, "disability" means
                      that you are unable to engage in any substantial gainful
                      activity by reason of any medically determinable physical
                      or mental impairment.

Leaves of Absence     For purposes of this option, your service does not
                      terminate when you go on a military leave, a sick leave or
                      another bona fide leave of absence, if the leave was
                      approved by the Company in writing and if continued
                      crediting of service is required by the terms of the leave
                      or by applicable law. But your service terminates when the
                      approved leave ends, unless you immediately return to
                      active work. In addition, at the discretion of the
                      Company, the vesting and exercisability of your option may
                      be suspended during a leave of absence, in accordance with
                      the Company's general policies, which may be amended from
                      time to time.

Restrictions on       The Company will not permit you to exercise this option if
Exercise              the issuance of shares at that time would violate any law
                      or regulation.

Notice of Exercise    When you wish to exercise this option, you must notify the
                      Company by filing the proper "Notice of Exercise" form at
                      the address given on the form. Your notice must specify
                      how many shares you wish to purchase. Your notice must
                      also specify how your shares should be registered (in your
                      name only or in your and your spouse's names as community
                      property or as joint tenants with right of survivorship).
                      The notice will be effective when it is received by the
                      Company.

                      If someone else wants to exercise this option after your
                      death, that person must prove to the Company's
                      satisfaction that he or she is entitled to do so.

Form of Payment       When you submit your notice of exercise, you must include
                      payment of the option exercise price for the shares you
                      are purchasing. Payment may be made in one (or a
                      combination of two or more) of the following forms:

                      .  Your personal check, a cashier's check or a money
                         order.

                      .  Certificates for shares of Company stock that you own,
                         along with any forms needed to effect a transfer of
                         those shares to the Company. The value of the shares,
                         determined as of the effective date of the option
                         exercise, will be applied to the option exercise price.
                         Instead of surrendering shares of Company stock, you
                         may attest to the ownership of those shares on a form
                         provided by the Company and have the same number of
                         shares subtracted from the option shares issued to you.
                         However, you may not surrender, or attest to the
                         ownership of, shares of Company stock in payment of

                                       3


                         the exercise price if your action would cause the
                         Company to recognize compensation expense (or
                         additional compensation expense) with respect to this
                         option for financial reporting purposes.

                      .  Irrevocable directions to a securities broker approved
                         by the Company to sell all or part of your option
                         shares and to deliver to the Company from the sale
                         proceeds an amount sufficient to pay the option
                         exercise price and any withholding taxes. (The balance
                         of the sale proceeds, if any, will be delivered to
                         you.) The directions must be given by signing a special
                         "Notice of Exercise" form provided by the Company.

                      .  Irrevocable directions to a securities broker or lender
                         approved by the Company to pledge option shares as
                         security for a loan and to deliver to the Company from
                         the loan proceeds an amount sufficient to pay the
                         option exercise price and any withholding taxes. The
                         directions must be given by signing a special "Notice
                         of Exercise" form provided by the Company.

Withholding           You will not be allowed to exercise this option unless you
Taxes and Stock       make arrangements acceptable to the Company to pay any
Withholding           withholding taxes that may be due as a result of the
                      option exercise. These arrangements may include
                      withholding shares of Company stock that otherwise would
                      be issued to you when you exercise this option. The value
                      of these shares, determined as of the effective date of
                      the option exercise, will be applied to the withholding
                      taxes.

Restrictions on       By signing this Agreement, you agree not to sell any
Resale                option shares at a time when applicable laws, Company
                      policies or an agreement between the Company and its
                      underwriters prohibit a sale. This restriction will apply
                      as long as your option has not expired.

Transfer of Option    Prior to your death, only you may exercise this option.
                      You cannot transfer or assign this option. For instance,
                      you may not sell this option or use it as security for a
                      loan. If you attempt to do any of these things, this
                      option will immediately become invalid. You may, however,
                      dispose of this option in your will or a beneficiary
                      designation.

                      Regardless of any marital property settlement agreement,
                      the Company is not obligated to honor a notice of exercise
                      from your former spouse, nor is the Company obligated to
                      recognize your former spouse's interest in your option in
                      any other way.


Retention Rights      Your option or this Agreement do not give you the right to
                      be retained by the Company or a subsidiary of the Company
                      in any capacity. The Company and its subsidiaries reserve
                      the right to terminate your service at

                                       4


                      any time, with or without cause.

Stockholder Rights    You, or your estate or heirs, have no rights as a
                      stockholder of the Company until you have exercised this
                      option by giving the required notice to the Company and
                      paying the exercise price. No adjustments are made for
                      dividends or other rights if the applicable record date
                      occurs before you exercise this option, except as
                      described below.

Buyout Rights         The Committee may at any time (a) offer to buy out for a
                      payment in cash or cash equivalents this option or (b)
                      authorize you to elect to cash out this option, in either
                      case at such time and based upon such terms and conditions
                      as the Committee shall establish.

Adjustments           In the event of a stock split, a stock dividend or a
                      similar change in Common Stock, the number of shares
                      covered by this option and the exercise price per share
                      may be adjusted in the same manner and to the same extent
                      as options are adjusted pursuant to the Company's 1999
                      Equity Incentive Plan.

Applicable Law        This Agreement will be interpreted and enforced under the
                      laws of the State of Delaware (without regard to their
                      choice-of-law provisions).

Other Agreements      This Agreement and the Notice of Stock Option Grant
                      constitute the entire understanding between you and the
                      Company regarding this option. Any prior agreements,
                      commitments or negotiations concerning this option are
                      superseded. This Agreement may be amended only by another
                      written agreement, signed by both parties.


By signing the cover sheet of this Agreement, you agree to all of the terms and
conditions described above and in the Notice of Stock option Grant.
