                                        and internal support functions.  You will report directly to the CEO.
                                        These duties and responsibilities may be expanded or contracted from
                                        time-to-time at the discretion of the CEO.

Base Salary:                            $14,583.33 per month, paid monthly.
Start Date:                             April 20, 1998, or such other date as mutually agreed in writing by you and
                                        the CEO.
Health Benefits:                        Pangea provides health and dental benefits through Blue Cross of California
                                        and through Kaiser.  Employees may choose between an HMO plan and a
                                        Preferred Provider Organization (PPO).

                                        Pangea will pay 95% of the cost of the HMO plan for employees plus 70% of the cost of the
                                        HMO coverage for the employees' dependents. Additional costs for coverage under the PPO
                                        shall be borne by employee.

                                        Pangea will provide life insurance and long term disability coverage at no expense to the
                                        employee.

Paid Time Off:                          You will have three weeks paid time off during the first year of your
                                        employment, which shall accrue over the course of the year on a bi-weekly
                                        basis.
Contribution Plan:                      Pangea has established a 401(k) plan with Piper Jaffray.  No company
                                        matching funds are provided at this time.  However, the plan allows for
                                        discretionary end-of-the-year company contributions.

Stock Options:                          Subject to Board approval, you will be granted stock options to purchase
                                        300,000 shares of common stock of the company, which will vest monthly at
                                        the rate of 1/48 of the total grant per month over four years of continuous
                                        employment.  The options are designed to qualify as Incentive Stock Options
                                        under the U.S. Income Tax Code, thus the exercise price of the options

<PAGE>

                                        will be based on the fair market value of the company at the time of grant
                                        (anticipated to be $0.55 per share upon your start date).

Change of Control:                      Upon the occurrence of a merger of the Company with or into any other
                                        entity or a sale or conveyance by the Company of all or substantially all

                                        Control.
