2005 STOCK INCENTIVE PLAN

EFFECTIVE AS OF NOVEMBER 15, 2005

SECTION 1. INTRODUCTION.

The Company’s Board of Directors adopts the Cisco Systems, Inc. 2005 Stock Incentive Plan on July 14, 2005; provided that, the Plan shall become effective upon its approval by Company shareholders. If the Company’s shareholders do not approve this Plan, no Awards will be made under this Plan.

The purpose of the Plan is to promote the long-term success of the Company and the creation of shareholder value by offering Key Employees an opportunity to share in such long-term success by acquiring a proprietary interest in the Company.

The Plan seeks to achieve this purpose by providing for discretionary long-term incentive Awards in the form of Options (which may constitute Incentive Stock Options or Nonstatutory Stock Options), Stock Appreciation Rights, Stock Grants and Stock Units.

The Plan shall be governed by, and construed in accordance with, the laws of the State of California (except its choice-of-law provisions). Capitalized terms shall have the meaning provided in Section 2 unless otherwise provided in this Plan or any related Stock Option Agreement, SAR Agreement, Stock Grant Agreement or Stock Unit Agreement.

The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company’s Articles of Incorporation or Bylaws, by contract, as a matter of law, or otherwise, or under any power that the Company may have to indemnify them or hold them harmless.

SECTION 4. GENERAL.

(a) General Eligibility. Only Employees, Directors, Non-Employee Directors and Consultants shall be eligible for designation as Key Employees by the Committee, in its sole discretion.

(c) Restrictions on Shares. Any Shares issued pursuant to an Award shall be subject to such rights of repurchase, rights of first refusal and other transfer restrictions as the Committee may determine, in its sole discretion. Such restrictions shall apply in addition to any restrictions that may apply to holders of Shares generally and shall also comply to the extent necessary with applicable law. In no event shall the Company be required to issue fractional Shares under this Plan.

A beneficiary designation may be changed by filing the prescribed form with the Company at any time before the Participant’s death. If no beneficiary was designated or if no designated beneficiary survives the Participant, then after a Participant’s death any vested Award(s) shall be transferred or distributed to the Participant’s estate.

(e) Performance Conditions. The Committee may, in its discretion, include performance conditions in an Award. If performance conditions are included in Awards to Covered Employees, then such Awards may be subject to the achievement of Performance Goals established by the Committee.
