Dear Wai:

I am happy to extend the following offer of employment to you with an anticipated start date of September 1, 2004 or earlier. This letter will confirm the terms of your offer of employment with BEA Systems, Inc. (“The Company”).

1. Position and Responsibilities. You will report to Alfred Chuang, CEO and President and serve in the position of Executive Vice President, Products.

The location of this position is San Jose, California (Company headquarters).

2. Compensation.

a) In consideration of your services, you will be paid a base salary of $17,916.67 per pay period (annualized base salary of $430,000). The salary will be payable semi-monthly in accordance with The Company’s standard payroll practices. Your base salary will be reviewed annually by the appropriate management of The Company in accordance with our review guidelines.

b) Your annual on-target compensation will be $752,500 (combined base and variable). Your variable earnings potential is $322,500 or 75% of your base salary. Your ability to earn the variable targets will be based upon both company and individual performance. The FY05 Bonus Plan Document is enclosed. We are happy to guarantee for the second half of FY05, such that you will receive the target amount of $161,250 at the end of each quarter (which shall be reduced by any actual bonus earned for this period).

c) We are also offering a $50,000 sign on bonus (gross before applicable withholdings and deductions) payable upon relocation of your family to the Bay Area.

d) We are also happy to relocate you to the San Francisco Bay Area, consistent with our Standard Domestic Executive Relocation Program. Your relocation must be completed by a date to be mutually determined and agreed upon by you and Alfred Chuang. Please refer to the relocation summary attachment for specifics of your relocation package.

e) In the event of involuntary termination without “Cause” (as defined below) within the first year of employment, you will be provided with a severance payment equal to 6 months of base salary as well as vested stock options equal to the amount that would otherwise vest upon the one year anniversary of your hire date, provided that you sign a standard transition agreement (to be drafted by BEA) that shall include, among other things, a general release of claims against BEA and its directors, officers, employees, shareholders, agents, successors and

assigns. In the event of an involuntary termination without “Cause” after the first year of employment, you will be entitled to a severance payment equal to 6 months of base salary, provided you sign a standard transition agreement (to be drafted by BEA) that will include, amont other things, a general release of claims against BEA and its directors, officers, employees, shareholders, agents, successors and assigns.

For the purposes of this paragraph 2(e), BEA may terminate your employment for “Cause” if: (i) you are convicted of, or plead no contest to, a crime of moral turpitude, or a fraud, felony or criminal act against The Company or any affiliated Company thereof or any of the assets of any of them; (ii) you engage in material misconduct or dishonest conduct that is detrimental to The Company (or any affiliated Company), (iii) you breach your Employee Proprietary Information and Inventions Agreement with The Company; (iv) you demonstrate material unfitness or unavailability for service or persistent unsatisfactory performance, which you fail to cure to the satisfaction of the Company for a period of thirty (30) days following notice to you by the Company, or, (v) your breach of the representations contained in paragraph 7 herein that your employment with the Company will not breach any contract or agreement with any former or existing employer, which shall include but not be limited to you being enjoined or prohibited, by a preliminary injunction of any court of competent jurisdiction, from performing all or a substantial portion of the duties which, in BEA’s sole discretion, are critical to the position of Executive Vice President, Products.

If BEA terminates your employment for “Cause,” it shall pay you all compensation to which you are owed through your termination date, and shall have no further obligations to you under this offer letter. For purposes of this offer letter, you agree that BEA may terminate your employment due to your death or Disability (which shall be defined as you being unable to perform the essential functions of your job for 120 consecutive days or more) and such termination shall not constitute a termination without “Cause” and you will not be eligible for the severance benefits described in paragraph 2(e) if your employment is terminated due your death or Disability.
