Pursuant to the Restricted Stock Unit Grant Notice ("Grant Notice") and this Restricted Stock Unit Award Agreement ("Agreement"), Siebel Systems, Inc. (the "Company") has awarded you a Restricted Stock Unit pursuant to Section 8 of the Siebel Systems, Inc. [1996/1998] Equity Incentive Plan (the "Plan") for the number of Shares as indicated in the Grant Notice (collectively, the "Award"). Defined terms not explicitly defined in this Agreement but defined in the Plan shall have the same definitions as in the Plan.

The details of your Award are as follows.

1. Purchase Price. The purchase price for each Share shall be $0.001.

2. Vesting. Subject to the limitations contained herein, your Award shall vest as provided in the Grant Notice.

3. Dividends. You shall be entitled to receive payments equal to any cash dividends and other distributions paid with respect to a corresponding number of Shares covered by your Award, provided that if any such dividends or distributions are paid in Shares, the Fair Market Value of such Shares shall be converted into additional Shares covered by the Award, and further provided that such additional Shares shall be subject to the same forfeiture restrictions and restrictions on transferability as apply to the Awards with respect to which they relate.

4. Distribution of Shares of Common Stock. The Company shall deliver to you a number of Shares of the Company's Common Stock ("Stock") equal to the number of vested Shares subject to your Award, including any additional Shares received pursuant to Section 3 above, on the date or dates that you elect (the "Settlement Date"). If such deferral election is made, the Committee shall, in its sole discretion, establish the rules and procedures for such deferrals.

5. Number of Shares. In the event of a subdivision of the outstanding Stock, a declaration of a dividend payable in Shares, a declaration of a dividend payable in a form other than Shares in an amount that has a material effect on the value of Shares, a combination or consolidation of the outstanding Stock into a lesser number of Shares, a recapitalization, a spinoff, a reclassification or a similar occurrence, the Committee shall make appropriate adjustments in the number of Shares covered by your Award.

6. Securities Law Compliance. You may not be issued any Shares under your Award unless the Shares are either (i) then registered under the Securities Act or (ii) the Company has determined that such issuance would be exempt from the registration requirements of the Securities Act. Your Award must also comply with other applicable laws and regulations governing the Award, and you shall not receive such Shares if the Company determines that such receipt would not be in material compliance with such laws and regulations.

9. Award not a Service Contract. Your Award is not an employment or service contract, and nothing in your Award shall be deemed to create in any way whatsoever any obligation on your part to continue in the service of the Company or a subsidiary, or on the part of the Company or a subsidiary to continue such service. In addition, nothing in your Award shall obligate the Company or a subsidiary, their respective stockholders, boards of directors or Employees to continue any relationship that you might have as an Employee of the Company or a subsidiary.

You shall not have voting or any other rights as a stockholder of the Company with respect to the Shares purchased pursuant to this Agreement until such Shares are issued to you pursuant to Section 4 of this Agreement. Upon such issuance, you will obtain full voting and other rights as a stockholder of the Company. Nothing contained in this Agreement, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between you and the Company or any other person.

11. Withholding Obligations.

(a) On or before the time you receive a distribution of Shares pursuant to your Award, or at any time thereafter as requested by the Company, you hereby authorize any required withholding from, at the Company's election, the Shares, payroll and any other amounts payable to you and otherwise agree to make adequate provision for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or a subsidiary, if any, which arise in connection with your Award.
