PROXY STATEMENT FOR GREATER BAY BANCORP

2005 ANNUAL MEETING OF SHAREHOLDERS

INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why Did You Send Me this Proxy Statement?

We sent you this Proxy Statement and the enclosed proxy card because our Board of Directors is soliciting your proxy to vote at the 2005 Annual Meeting of Shareholders. This Proxy Statement summarizes the information you need to know to cast an informed vote at the Annual Meeting. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card.

Along with this Proxy Statement, we are also sending you the Greater Bay Bancorp 2004 Summary Annual Report to Shareholders and 2004 Annual Report on Form 10-K, which includes our financial statements. Greater Bay Bancorp is also referred to in this Proxy Statement as “Greater Bay” or the “Company.”

Who is Entitled to Vote?

We will begin sending this Proxy Statement, the attached Notice of Annual Meeting and the enclosed proxy card on or about April 25, 2005 to all shareholders entitled to vote. Shareholders who were the record owners of Greater Bay Bancorp Common Stock and Series B Preferred Stock at the close of business on April 4, 2005 are entitled to vote. On this record date, there were 51,019,449 shares of Greater Bay Bancorp Common Stock and 2,030,863 shares of Series B Preferred Stock outstanding. The Series B Preferred Stock votes with the Common Stock on all matters presented to the common shareholders. Our Common Stock and Series B Preferred Stock are our only classes of outstanding stock. In this Proxy Statement, we refer to the Common Stock and the Series B Preferred Stock together as the “Capital Stock.”

What Constitutes a Quorum?

A majority of the outstanding shares of the Capital Stock entitled to vote at the Annual Meeting must be present, in person or by proxy, in order to constitute a quorum. We can only conduct the business of the Annual Meeting if a quorum has been established. We will include proxies marked as abstentions and broker non-votes in determining the number of shares present at the Annual Meeting.

How Many Votes Do I Have?

Each share of Common Stock entitles you to one vote. Each share of Series B Preferred Stock entitles you to 1.67 votes on all matters voted together with the Common Stock. The proxy card indicates the number of votes that you have as of the record date. When we refer to our “outstanding Capital Stock” in this Proxy Statement, we are referring to the sum of (i) the number of shares of our Common Stock outstanding on the record date and (ii) the number of shares of Series B Preferred Stock outstanding on the record date multiplied by 1.67.

How Do I Vote By Proxy?

Whether or not you plan to attend the Annual Meeting, we urge you to complete, sign and date the enclosed proxy card and to return it promptly in the envelope provided. You may also vote electronically over the Internet or by telephone (see below). Returning the proxy card will not affect your right to attend the Annual Meeting and vote.

If you properly fill in your proxy card and send it to us in time to vote, your “proxy” (one of the individuals named on your proxy card) will vote your shares as you have directed. If you sign the proxy card but do not make specific choices, your proxy will vote your shares as recommended by the Board of Directors as follows:

• “FOR” the election of all five nominees for director;

• “FOR” approval of the Greater Bay Bancorp 2005 Long Term Incentive Plan;

• “FOR” approval of the Greater Bay Bancorp 2005 Executive Incentive Plan;

• “FOR” ratification of the selection of the independent registered public accounting firm for 2005; and

• “AGAINST” the shareholder proposal regarding restrictions on the Company’s ability to issue preferred stock, if that proposal is introduced at the Annual Meeting.

If any other matter is presented, your proxy will vote in accordance with the recommendation of the Board of Directors, or, if no recommendation is given, in accordance with his or her best judgment. At the time this Proxy Statement went to press, we knew of no matters which needed to be acted on at the Annual Meeting, other than those discussed in this Proxy Statement.

What is the Effect of Broker Non-Votes and Abstentions?

If you hold your shares of Capital Stock in “street name” (that is, through a broker or other nominee) and you fail to instruct your broker or nominee as to how to vote your shares of Capital Stock, your broker or nominee may, in its discretion, vote your shares “FOR” the election of the nominees for director set forth in this Proxy Statement, and “FOR” ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2005. Brokers may not use their discretionary authority to vote (broker non-votes) on the proposal to adopt the Greater Bay Bancorp 2005 Long Term Incentive Plan, on the proposal to adopt the Greater Bay Bancorp 2005 Executive Incentive Plan or on the shareholder proposal. Since the proposal to adopt the Greater Bay Bancorp 2005 Long Term Incentive Plan and the Greater Bay Bancorp 2005 Executive Incentive Plan each require the approval of a majority of the votes cast under the Internal Revenue Code and rules of The Nasdaq Stock Market, broker non-votes and abstentions will have no effect on these proposals.

California law requires the following two votes to adopt any proposal (other than the election of directors): (1) the affirmative vote of a majority of the shares represented and voting at the Annual Meeting, unless the vote of a greater number is required by law or by our Restated Articles of Incorporation and (2) the affirmative vote of at least a majority of the shares required to constitute a quorum. In determining whether the first vote under (1) has been obtained, abstentions and broker non-votes are not treated as shares voting and therefore will not affect the vote on any proposal. In determining whether the second vote under (2) has been obtained, abstentions and broker non-votes will have the effect of votes cast AGAINST the proposals to ratify our independent registered public accounting firm and on the shareholder proposal. That is, abstentions and broker non-votes will reduce the number of affirmative votes and therefore reduce the total percentage of votes the proposal might otherwise have received.

May I Vote Electronically over the Internet or by Telephone?

Shareholders whose shares are registered in their own names may vote either over the Internet or by telephone. Special instructions to be followed by any registered shareholder interested in voting via the Internet or by telephone are set forth on the enclosed proxy card. The Internet and telephone voting procedures are designed to authenticate the shareholder’s identity and to allow shareholders to vote their shares and confirm that their voting instructions have been properly recorded.

If your shares are registered in the name of a bank or brokerage firm and you have not elected to receive your Proxy Statement over the Internet, you may be eligible to vote your shares electronically over the Internet or

2

by telephone. A large number of banks and brokerage firms are participating in the ADP Investor Communication Services online program. This program provides eligible shareholders who receive a paper copy of this Proxy Statement the opportunity to vote via the Internet or by telephone. If your bank or brokerage firm is participating in ADP’s program, your proxy card will provide the instructions. If your proxy card does not reference Internet or telephone information, please complete and return the proxy card in the self-addressed, postage paid envelope provided.

May I Change My Vote After I Return My Proxy?

Yes. If you fill out and return the enclosed proxy card, or vote by telephone or the Internet, you may change your vote at any time before the vote is conducted at the Annual Meeting. You may change your vote in any one of four ways:

• You may send to the Company’s Corporate Secretary another completed proxy card with a later date.

• You may notify the Company’s Corporate Secretary in writing before the Annual Meeting that you have revoked your proxy.

• You may attend the Annual Meeting and vote in person.

• If you have voted your shares by telephone or Internet, you can revoke your prior telephone or Internet vote by recording a different vote, or by signing and returning a proxy card dated as of a date that is later than your last telephone or Internet vote.

How Do I Vote in Person?

If you plan to attend the Annual Meeting and vote in person, we will give you a ballot form when you arrive. However, if your shares are held in the name of your broker, bank or other nominee, you must bring a power of attorney from your nominee in order to vote at the Annual Meeting.

What Vote is Required to Approve Each Proposal?

Proposal 1:

Elect Five Directors The five nominees for director who receive the most votes will be elected. So, if you do not vote for a particular nominee, or you indicate “WITHHOLD AUTHORITY” to vote for a particular nominee on your proxy card, your vote will not count either “for” or “against” the nominee. Our Restated Articles of Incorporation do not permit cumulative voting.

Proposal 2:

Approval of the Greater Bay Bancorp 2005 Long Term Incentive Plan The affirmative vote of a majority of the votes cast at the Annual Meeting is required to approve the proposal to approve the Greater Bay Bancorp 2005 Long Term Incentive Plan.

Proposal 3:

Approval of the Greater Bay Bancorp 2005 Executive Incentive Plan The affirmative vote of a majority of the votes cast at the Annual Meeting is required to approve the proposal to approve the Greater Bay Bancorp 2005 Executive Incentive Plan.

Proposal 4:

Ratify Selection of Independent Registered Public Accounting Firm The affirmative vote of a majority of the votes cast at the Annual Meeting on this proposal is required to ratify the selection of the independent registered public accounting firm (which shares voting affirmatively also constitute at least a majority of the required quorum).

3

Proposal 5:

Shareholder Proposal to Restrict the Use of Preferred Stock The affirmative vote of a majority of the votes cast at the Annual Meeting on this proposal is required to approve the shareholder proposal (which shares voting affirmatively also constitute at least a majority of the required quorum).

What are the Costs of Soliciting these Proxies?

We will pay all the costs of soliciting these proxies. In addition to mailing proxy soliciting material, our directors, officers and employees also may solicit proxies in person, by telephone or by other electronic means of communication for which they will receive no compensation. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward the proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their reasonable expenses. We have hired Georgeson Shareholder Communications Inc. to seek the proxies of custodians, such as brokers, who hold shares which belong to other people. This service will cost the Company approximately $6,500.

How Do I Obtain an Annual Report on Form 10-K?

We have enclosed a copy of our 2004 Annual Report on Form 10-K with this Proxy Statement. If you would like another copy of our 2004 Annual Report on Form 10-K, we will send you one without charge. The Annual Report on Form 10-K includes a list of exhibits filed with the SEC, but does not include the exhibits. If you wish to receive copies of the exhibits, we will send them to you. Expenses for copying and mailing them to you will be your responsibility. Please write to:

INFORMATION ABOUT GREATER BAY BANCORP STOCK OWNERSHIP

The Securities and Exchange Commission has defined “beneficial ownership” to mean more than ownership in the usual sense. For example, a person has beneficial ownership of a share not only if he owns it directly, but also if he has the power to vote, sell or otherwise dispose of the share. Beneficial ownership also includes that number of shares that a person has the right to acquire within 60 days of April 4, 2005. Two or more persons might count as beneficial owners of the same share.

How Much of Greater Bay Bancorp’s Capital Stock is Owned by Directors, Executive Officers and Greater than 5% Shareholders?

The following table shows, as of April 4, 2005, beneficial ownership of Greater Bay Bancorp Common Stock by each of Greater Bay Bancorp’s directors, nominees for director, the named executive officers, our directors and executive officers as a group, and persons known to us who own more than 5% of our Common Stock.

CORPORATE GOVERNANCE PRINCIPLES AND BOARD MATTERS

The Board of Directors is committed to good business practices, transparency in financial reporting and the highest level of corporate governance. To that end, the Board continually reviews its governance policies and practices, as well as the requirements of the Sarbanes-Oxley Act of 2002 and the listing standards of The Nasdaq Stock Market, to ensure that such policies and practices are compliant and up to date.

Corporate Governance Guidelines

Our corporate governance guidelines provide for, among other things:

• A Board consisting predominantly of non-management directors and a substantial majority of whom are independent directors;

• Periodic executive sessions of non-management directors;

• An Audit Committee, Compensation Committee and Board Governance and Nominating Committee consisting entirely of independent directors;

• An annual self-evaluation process for the Board and its committees;

• Director education and orientation;

• Ethical conduct of directors and adherence to a duty of loyalty to the Company; and

• Establishment of a management succession plan.

Board Qualification and Selection Process

Our corporate governance guidelines contain Board membership criteria that apply to all Board Governance and Nominating Committee-recommended nominees for a position on our Board. Under these criteria, members of the Board should possess the highest personal and professional ethics and integrity and be devoted to representing the best interests of Greater Bay and its shareholders. Members of the Board should have a meaningful ownership interest in Greater Bay stock and are expected to act in a manner consistent with the duties of care and loyalty owed to the Company. New directors elected or appointed to the Board after January 1, 2004 will be required to resign after the expiration of the elected term during which they turn 75 years of age. This mandatory retirement age does not apply to those directors in office as of December 31, 2003.

Other important factors the Board Governance and Nominating Committee will consider include current knowledge, experience and contacts in Greater Bay’s industries and other industries relevant to Greater Bay’s business, ability to work together with other Board members, ability to serve as a significant and active resource for referrals and business development and the ability to commit adequate time to serve as a director of Greater Bay.

One of the goals of the Board Governance and Nominating Committee is to maintain a strong and experienced Board by annually assessing the Board’s business background. We seek to have a Board of Directors with a diversity of experiences in business, finance, public service and other areas relevant to our business, and who bring diverse perspectives and backgrounds to the Company. The Board Governance and Nominating Committee will conduct an annual assessment of the composition of the Board, and will advise the Board on any proposed changes or enhancements to Board composition and structure. If the Board agrees that the proposed changes or enhancements are necessary, the Board Governance and Nominating Committee will undertake a search process. The Board Governance and Nominating Committee has the authority to retain a search firm to identify director candidates.

8

Consideration of Shareholder Nominees

The policy of the Board Governance and Nominating Committee is to consider properly submitted shareholder recommendations for candidates for membership on the Board of Directors. In evaluating potential nominees, the Board Governance and Nominating Committees will look at the same factors described under the heading “Board Qualification and Selection Process” above. Recommendations must be submitted in writing to the attention of the Chair of the Board Governance and Nominating Committee at the following address, and should include a detailed resume:

Chair, Board Governance and Nominating Committee

Greater Bay Bancorp

1900 University Avenue, 6^th Floor

East Palo Alto, California 94303

INFORMATION ABOUT DIRECTORS AND EXECUTIVE OFFICERS

The Board of Directors

The Board of Directors oversees our business and monitors the performance of management. In accordance with corporate governance principles, the Board does not involve itself in day-to-day operations. The directors keep themselves informed through, among other things, discussions with the Chief Executive Officer, other key executives and our principal outside advisers (legal counsel, outside auditors, investment bankers and other consultants), by reading reports and other materials that we send them and by participating in Board and committee meetings.

Greater Bay Bancorp’s Bylaws currently permit the number of Board members to range from 11 to 21, leaving the Board authority to fix the exact number of directors within that range. The Board has fixed the exact number of directors at 12. The Board of Directors has determined that all of its directors, except for Mr. Scordelis, Mr. de Grosz, Mr. Kalkbrenner and Mr. Matteson, are “independent” as defined by the applicable rules and regulations of The Nasdaq Stock Market.

The Board held 12 meetings during 2004. Each incumbent director attended at least 75% of the total number of Board meetings plus meetings of the standing committees on which that particular director served.

The Committees of the Board

The Board may delegate portions of its responsibilities to committees of its members. These standing committees of the Board meet at regular intervals to attend to their particular areas of responsibility. Our Board has five standing committees: the Audit Committee, Compensation Committee (which has an Executive Compensation Subcommittee), Executive Committee, Asset-Liability Management Committee, and Board Governance and Governance and Nominating Committee. The charters of the Audit, Compensation and Board Governance and Nominating Committees are available on our website at www.gbbk.com.

Audit Committee.    Greater Bay has a separately designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended. The Audit Committee Charter adopted by the Board sets out the responsibilities, authority and specific duties of the Audit Committee. The Audit Committee Charter was included in the proxy statement for our 2004 annual meeting of shareholders. Pursuant to the charter, the Audit Committee has the following primary duties and responsibilities:

• To monitor the integrity of our financial reporting process and systems of internal controls regarding finance, accounting and legal compliance;

• To monitor the qualifications and independence of our independent registered public accounting firm;

• To monitor the performance of our independent and internal audit functions; and

• To provide an avenue of communication among the independent auditors, management and the Board of Directors.

The Audit Committee has the authority to conduct any investigation appropriate to fulfilling its responsibilities and has direct access to the independent auditors as well as anyone in the Greater Bay organization. The Audit Committee has the ability to retain special legal or accounting experts, or such other consultants, advisors or experts it deems necessary in the performance of its duties and shall receive appropriate funding from the Company for payment of compensation to any such person. The Audit Committee works closely with management and our independent auditors. The Audit Committee consists of Messrs. Seiler (Chairman), Libarle and McLaughlin each of whom is “independent,” as defined by the rules and regulations of The Nasdaq Stock Market. The Board of Directors has designated Messrs. Seiler and McLaughlin as “audit committee financial experts,” as that term is defined by SEC regulations issued under the Sarbanes-Oxley Act of 2002. The Audit Committee held 17 meetings during 2004.

Audit Committee Report

The following Audit Committee Report does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filings under the Securities Act of 1933 or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), except to the extent we specifically incorporate this Report by reference.

The Audit Committee reports to the Board of Directors and is responsible for overseeing and monitoring financial accounting and reporting, the system of internal controls established by management and the audit process of Greater Bay Bancorp.

Management is responsible for the financial reporting process, including the system of internal controls, and for the preparation of consolidated financial statements in accordance with generally accepted accounting principles. Greater Bay Bancorp’s independent registered public accounting firm is responsible for auditing those financial statements. The Audit Committee’s responsibility is to monitor and review these processes. The Audit Committee relies, without independent verification, on the information provided to it and on the representations made by management, the internal auditors and the independent registered public accounting firm.

In discharging its oversight responsibility, the Audit Committee hereby reports as follows:

1. The Audit Committee has met and held discussions with management and PricewaterhouseCoopers LLP, the independent registered public accounting firm for Greater Bay Bancorp. Management represented to the Audit Committee that all consolidated financial statements were prepared in accordance with generally accepted accounting principles. The Audit Committee has reviewed and discussed the consolidated financial statements with management and the independent registered public accounting firm.

2. The Audit Committee has discussed with the independent registered public accounting firm matters required to be discussed by Statement on Auditing Standards No. 61 (Communications with Audit Committees).

3. The Audit Committee has obtained from the independent registered public accounting firm a formal written statement describing all relationships between Greater Bay Bancorp and such firm that bear on the firm’s independence consistent with Independence Standards Board Standard No. 1, Independence Discussions with Audit Committee. The Audit Committee discussed with the independent registered public accounting firm any relationships that may impact the firm’s objectivity and independence and satisfied itself as to the firm’s independence.

Respectfully submitted by the members of the Audit Committee:

Donald H. Seiler, Chairman

Daniel G. Libarle

Compensation Committee.    Greater Bay has a separately designated Compensation Committee, which consists entirely of independent directors as defined by the rules and regulations of The Nasdaq Stock Market. Pursuant to its charter, the Compensation Committee has the following responsibilities:

• Review and approve our compensation philosophy;

• Review industry compensation practices and our relative compensation positioning;

• Issue an annual report on executive compensation for inclusion in our proxy statement;

11

• Annually review director compensation and recommend to our board for approval the form and amount of director compensation;

• Review and approve our compensation programs, plans and awards;

• Administer our short-term and long-term incentive plans and other stock or stock-based plans; and

• Review and approve general employee welfare benefit plans and other plans on an as needed basis.

During 2004, the Compensation Committee held 12 meetings and the Executive Compensation Subcommittee held 3 meetings. Messrs. Gatto, Lund, McLaughlin and Seiler are members of the Compensation Committee.

Board Governance and Nominating Committee.    The purposes of the Board Governance and Nominating Committee include: (1) identifying individuals qualified to become Board members and making recommendations to the full Board of candidates for election to the Board; (2) recommending to the Board corporate governance guidelines; (3) leading the Board in an annual review of its performance; and (4) recommending director appointments to Board committees. Mr. Gatto chairs the Board Governance and Nominating Committee, and Ms. Meier serves as the Vice-Chair. The other members of the committee are Messrs. Libarle, Lund and Marcus. All of the members of the Board Governance and Nominating Committee are “independent” directors as defined by the rules and regulations of The Nasdaq Stock Market. The Board Governance and Nominating Committee held 5 meetings during 2004.

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation Committee serves or has served as an officer or employee of Greater Bay Bancorp or its subsidiaries. In addition, Mr. Seiler has an interest in a building leased by Greater Bay Bank, National Association, a subsidiary of the Company (referred to herein as Greater Bay Bank). See “Certain Relationships and Related Transactions.”

Section 16(a) Beneficial Ownership Reporting Compliance by Directors and Executive Officers

Section 16(a) of the Exchange Act requires our directors and executive officers to file reports with the SEC and The Nasdaq Stock Market on changes in their beneficial ownership of Greater Bay Bancorp Capital Stock, and to provide the Company with copies of the reports.

Based solely on our review of these reports or of certifications to us that no report was required to be filed, we believe that all of our directors and executive officers complied with all Section 16(a) filing requirements applicable to them during the 2004 fiscal year, except for one late Form 4 filing by Mr. Marcus related to one transaction. In addition, former director Warren Thoits had one late filing relating to two transactions, former director T. John Whalen had one late filing relating to one transaction and former officer Shawn Saunders had one late filing relating to one transaction.

How We Compensate Directors

Greater Bay Bancorp has a policy of compensating directors for their service on the Board and for their attendance at committee meetings. In 2004, Mr. Matteson, as Chairman of the Board, received an annual retainer of $82,000 and Mr. Gatto, as a Vice Chairman of the Board, received an annual retainer of $34,000. All other non-officer directors received annual retainers of $22,000. In addition, each non-officer director receives $667 for each regular Board meeting attended. Mr. Scordelis does not receive any compensation as a director. His compensation is discussed below in the section entitled “How We Compensate Executive Officers.”

In 2004, non-officer committee members received annual retainers as follows: (i) Audit Committee, $14,000; (ii) Executive Committee, $22,000; (iii) Compensation Committee, $4,000; (iv) Loan Committee,

12

$18,000; (v) Asset-Liability Management Committee, $10,000; (vi) Marketing Committee, $2,000; (vii) Trust Oversight Committee, $4,000; and (viii) Board Governance and Nominating Committee, $2,000. The Chairmen of these committees received additional annual retainers in 2004, as follows: (a) Audit, $30,000; (b) Asset-Liability Management, $16,000; (c) Marketing, $6,000; (d) Trust Oversight Committee, $4,000; and (e) Board Governance and Nominating and Compensation Committees, $10,000 combined.

In addition, directors are eligible to participate in Greater Bay Bancorp’s 1996 Stock Option Plan. For their contributions in 2004, non-officer directors received restricted stock grants, as follows: Mr. Matteson, 10,000 shares; Mr. Gatto, 5,500 shares; Mr. Seiler, 9,000 shares; Messrs. Kalkbrenner and McLaughlin, 4,000 shares each; and Messrs. Libarle, Lund, Marcus and Thompson and Ms. Meier, 3,000 shares each. The restrictions lapse 50% annually over a two-year period. Directors are also entitled to the protection of certain indemnification provisions in Greater Bay Bancorp’s Restated Articles of Incorporation, Bylaws and indemnification agreements.

Certain Relationships and Related Transactions

Greater Bay Bank has had and expects in the future to have banking transactions in the ordinary course of business with our directors and officers or associates of our directors and officers. We may also have banking transactions with corporations of which our directors or officers may own a controlling interest, or also serve as directors or officers. These transactions have taken place and will take place on substantially the same terms, including interest and collateral, as those prevailing for comparable transactions with others, and comply with the provisions of the Sarbanes-Oxley Act of 2002. We believe that these transactions involving loans did not present more than the normal risk of noncollectibility or present other unfavorable features.

Greater Bay Bank leases its offices at 420 Cowper Street, Palo Alto, California 94301 from MPB Associates, LLC. A director of Greater Bay Bancorp, Mr. Seiler owns a 10% non-controlling member interest in MPB Associates, LLC. The managing member of MPB Associates, LLC is Matteson Real Estate Equities, Inc. in which Mr. Matteson has a 47% ownership interest. The lease has been extended through January 2010. Greater Bay Bank pays monthly rent of $77,500 for the leased space, subject to an annual rent adjustment of 3.5%. Additionally, Greater Bay Bank pays real property taxes, utilities and building insurance, to the extent they exceed, on an annual basis, $1.40 per rentable square foot, $1.60 per rentable square foot, and $0.17 per rentable square foot, respectively. The lease also contains a provision granting Greater Bay Bank a right of first refusal to purchase the building during the term of the lease upon the same terms and conditions that the landlord is willing to accept from a third party.

ABD, a wholly owned subsidiary of Greater Bay, leases its offices at 305 Walnut Street, Redwood City, California 94063, from 305 Walnut Associates, LLC. That entity is owned 50% by Matteson Real Estate Equities, Inc. and 50% by 305 Walnut Partners. Two directors of Greater Bay, Messrs. Matteson and de Grosz, have ownership interests in 305 Walnut Associates, LLC. Mr. Matteson owns 47% of Matteson Real Estate Equities, Inc. and, therefore, 23.5% of 305 Walnut Associates, LLC. Mr. de Grosz owns 25% of 305 Walnut Partners and, therefore, 12.5% of 305 Walnut Associates, LLC. The lease term extends through November 12, 2010. ABD pays a monthly rent of $223,000 (subject to an annual rent adjustment of 3%) and all property taxes and operating expenses associated with the leased premises. The lease also provides for a rent adjustment beginning in 2006 based on the greater of (a) the base rent as then in effect or (b) 90% of the fair market rental value at that time.

ABD has also entered into a lease dated December 2, 2002, with 42 Natomas Park Drive, LLC for office space in Sacramento, California. Mr. de Grosz has a 7.14% interest in 42 Natomas Park Drive, LLC. Under the lease, ABD pays a monthly rent of $82,000 (subject to an annual rent adjustment of 3%) and all property taxes and operating expenses associated with the leased premises.

Employment Contracts, Change in Control Arrangements and Termination of Employment

Employment Contracts.    Effective January 1, 2004, the Company entered into a five-year employment agreement with Byron A. Scordelis, our President and Chief Executive Officer. The agreement provides for, among other things (a) a base salary of no less than $575,000 per year, which the Board may adjust annually in its discretion; (b) bonus compensation at the discretion of the Compensation Committee based on the Company’s pre-tax net profits; (c) a disability insurance policy, the premiums of which (up to a maximum of $5,000 per year) will be paid by the Company; (d) the grant of an option to purchase 50,000 shares of Common Stock and a restricted stock grant of 10,000 shares at the first Compensation Committee meeting following the effective date of the Agreement, with future option grants or restricted stock grants in the sole discretion of the Board of Directors; (e) five weeks annual vacation; (f) an automobile allowance of $1,000 per month; (g) supplemental retirement benefits (see “Supplemental Executive Retirement Plan” below); and (h) reimbursement for ordinary and necessary expenses incurred by Mr. Scordelis in connection with his employment, including country club and health club dues. Greater Bay may terminate the agreement with or without cause.

Upon Mr. Scordelis’ involuntary termination of employment for any reason (other than for cause) or voluntary termination for good reason, Mr. Scordelis will be entitled to receive severance benefits equal to 30 months of base salary at the rate in effect immediately preceding the termination and an amount equal to three times the average of any annual or incentive bonuses paid to him over the three years immediately preceding such termination. In addition, all restricted stock, stock options and other equity incentives held by Mr. Scordelis would immediately vest. As defined in the agreement, “good reason” means (i) any diminution in Mr. Scordelis’ title, position, duties or responsibilities; (ii) any adverse change in his base salary; (iii) any relocation outside of the San Francisco Bay Area or (iv) any material breach of the agreement by the Company.

In the event of an involuntary termination of employment for any reason (other than for cause) or any event occurs which, among other things, constitutes a demotion, significant diminution or constructive termination of Mr. Scordelis’ employment within two years of a change in control of Greater Bay, Mr. Scordelis will be entitled to receive severance pay equal to 36 months of base salary at the rate in effect immediately

18

preceding the termination plus an amount equal to three times the average of any annual or incentive bonus paid to him over the three years immediately preceding such termination. In addition, Mr. Scordelis is entitled to receive this change in control payment in the event he voluntarily terminates his employment for any reason within 30 days immediately following the expiration of the sixth month following a change in control. Any change in control severance payment shall be increased to provide Mr. Scordelis with substantially the same economic benefit he would otherwise be entitled to in the event any portion of the amounts owed to Mr. Scordelis is subject to an excise tax.

Change in Control Plans.    The Greater Bay Bancorp Board of Directors has adopted the Greater Bay Bancorp Change in Control Pay Plan I and the Greater Bay Bancorp Change in Control Pay Plan II, as amended and restated effective January 1, 2005 to provide eligible employees and key executives with severance benefits upon their termination of employment on account of a change in control.

The plans define change in control as a sale or change in ownership of Greater Bay Bancorp and provide participants with a severance benefit based on the participant’s title or position with Greater Bay Bancorp or a subsidiary as of the date he or she terminates employment in connection with a change in control. “Pay” for purposes of the plans means the annual salary paid to an employee and the average bonus paid to the employee in the three most recent years. Under the Change in Control Plan II, the executive officers would be entitled to receive a severance benefit equal to 30 months of Pay plus an amount equal to any excise taxes that may be imposed on them.

Severance Plans.    The Greater Bay Bancorp Board has also adopted the Greater Bay Bancorp Severance Plan I (formerly, the Greater Bay Bancorp Termination and Layoff Pay Plan I) and the Greater Bay Bancorp Severance Plan II (formerly the Greater Bay Bancorp Termination and Layoff Pay Plan II), as amended and restated as of January 1, 2005. The plans provide each participant with a severance benefit based on the participant’s pay, full years of service with Greater Bay Bancorp or a subsidiary, and his or her title or position in Greater Bay Bancorp or the subsidiary as of the date of his or her involuntary termination of employment due to layoff. “Pay” for purposes of the plans means the annual salary paid to an employee.

Under the Severance Plan II, Messrs. Westfall, Shannon, and Johnson and Ms. Hiraoka would be entitled to a severance benefit of no more than 18 months of Pay. Severance benefits that would be payable to Mr. Scordelis are covered by his employment agreement (see above).

Retirement Agreement.    On December 1, 2003, we entered into a Consulting Agreement with Mr. Kalkbrenner in conjunction with his retirement from Greater Bay as President and Chief Executive Officer. Pursuant to this Agreement, Mr. Kalkbrenner has agreed to serve as a consultant to Greater Bay for two years commencing on January 1, 2004. Mr. Kalkbrenner is paid $26,000 per month for providing approximately 80 hours per month of consulting services for the first 12 months of the agreement and $13,000 per month for providing approximately 40 hours per month of consulting services for the last 12 months of the agreement. Mr. Kalkbrenner will be eligible for a bonus at the discretion of the Board of Directors and receives the same meeting fees as other members of the Board and Board Committees (see “How We Compensate Directors”). Mr. Kalkbrenner’s authorized expenses are reimbursed as well as the cost of monthly overhead charges, including any rent on office space which is not provided by the Company.

Greater Bay also pays Mr. Kalkbrenner’s country club membership dues for the first year of the term of the consulting agreement. The Company transferred to Mr. Kalkbrenner the country club membership purchased by the Company when he served as President and Chief Executive Officer. In addition, Greater Bay will pay 50% of the premiums for disability insurance coverage Greater Bay will obtain for the full term of Mr. Kalkbrenner’s consulting agreement. While Mr. Kalkbrenner serves on the Company’s Executive Committee, he will be granted annually an option for the number of shares granted Executive Committee members. In the event of a change in control of Greater Bay during the term of the Agreement, Mr. Kalkbrenner will be entitled to an amount equal to three times the cumulative monthly consulting compensation payable over the 24-month term of the Agreement.

19

Any change in control severance payment will be increased to provide Mr. Kalkbrenner with substantially the same economic benefit he would otherwise be entitled to under the Agreement in the event any portion of the amounts owed to Mr. Kalkbrenner is subject to an excise tax.

Greater Bay Bancorp’s Stock Option Plan.    The Greater Bay Bancorp Board of Directors has adopted the Greater Bay Bancorp Amended and Restated 1996 Stock Option Plan, referred to as the “Option Plan.” Options and restricted stock granted under the Option Plan contain a provision that takes effect upon a “change in control” of Greater Bay Bancorp. Prior to the occurrence of any such change in control, all options granted under the Option Plan will become immediately exercisable and all restrictions on restricted stock will immediately lapse.

Supplemental Executive Retirement Plan.    The Company maintains a defined benefit supplemental employee retirement plan (SERP) for its executive officers and certain other employees. The SERPs are unfunded and are not qualified under IRC Section 401(a). Under these agreements, the Company is generally obligated to provide for each such employee who continues in employment for a specified period, or, if earlier, until the employee’s total disability or our change in control, a monthly benefit beginning at the employee’s retirement and continuing for the employee’s life in the amount defined or determined in each agreement. In most cases, a related split-dollar life insurance agreement provides a death benefit for the employee’s spouse or other beneficiaries. Certain current and former executive employees have additional supplemental retirement benefits that are funded through secular trusts. The Company is obligated to make annual contributions to the secular trusts for the benefit of these employees in the amounts necessary to provide specified benefit payments beginning at retirement age. The annual contributions to the trusts are taxable income to these employees, and annually, the Company pays withholding taxes for the benefit of these employees in the additional amounts necessary to cover their income and employment tax liabilities on the contributions to the trusts. The secular trusts hold life insurance policies on these employees under which the contributions are invested and benefits paid. The benefit for an executive under this plan is fixed when the executive enters the plan at an amount then estimated to be 60% (70% for Mr. Scordelis) of projected salary at the earlier of ten years of participation in the plan or age 62, based on the executive’s base salary when he or she enters the plan with assumed annual salary increases of 4% thereafter (no assumed salary increases for Mr. Scordelis). This amount is periodically reviewed by the Company and may be adjusted from time to time, but the Company has no obligation to make any adjustments.

For Messrs. Scordelis, Shannon and Johnson, the retirement benefit has two components, an unfunded benefit that is payable by the Company for the executive’s lifetime and a funded benefit provided through an insurance policy owned by a secular trust established for the benefit of the executive. The funded portion of the benefit is “trued up” at time of retirement to an amount that would provide a specified benefit each year until the executive reaches age 85. Once the “true up” occurs at retirement, the Company has no further funding obligation and the executive may take payment of the benefit from the trust in any manner that he or she chooses. Ms. Hiraoka has only an unfunded benefit. Similarly, Mr. Westfall’s proposed agreement will include only an unfunded benefit.

The estimated annual benefits (unfunded and funded) payable at age 62 for the named executive officers are set forth in the table below:

Name	Annual Benefit (Unfunded)		Annual Benefit (Funded)
Mr. Scordelis	$	161,000	$	144,900
Mr. Westfall		—		—
Mr. Shannon	$	115,459	$	69,276
Mr. Johnson	$	80,009	$	58,477
Ms. Hiraoka	$	204,957		—

20

The retirement benefit is fully vested on the earlier of 10 years of participation in the plan or the executive’s attainment of age 62. If the executive voluntarily terminates employment with the Company, he or she is 0% vested in the unfunded portion of the benefit prior to becoming fully vested. If the Company terminates the executive without cause, he or she will be 20% vested for each year of participation in the plan beginning with the sixth year of participation until fully vested. An executive will become fully vested in the event his or her employment terminates as a result of his or her disability or a change in control of the Company. Prior to becoming fully vested, the executive is entitled to receive the funded portion of his or her own benefit only to the extent provided by the assets then held in the secular trust.

As of December 31, 2004, Mr. Scordelis had four years of participation, Mr. Shannon had three years of participation, Mr. Johnson had seven years of participation and Ms. Hiraoka had two years of participation.

The Company is obligated to make annual contributions to the secular trusts for the funded portions of the supplemental retirement benefits provided to executives. The annual contributions to the trusts are taxable income to the executives, and the Company pays the executives’ income and employment withholding tax liabilities on such contributions.

The following table sets forth the amounts deposited into individual trusts for the following persons, combined with amounts the Company paid for income and employment tax withholding on the tax grossed up value of such amounts on behalf of these persons:

Name	Trust Contributions
	2004		2003		2002

Mr. Westfall		—		—		—
Mr. Shannon	$	154,695	$	154,695		—
Mr. Johnson	$	150,713	$	146,606	$	156,002

Compensation Committee’s Report on Executive Compensation

Set forth below is a report of our Compensation Committee addressing the compensation philosophy and policies for 2004 applicable to our executive officers.

Compensation Committee Report

The Report of the Compensation Committee of the Board of Directors shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933 or under the Securities Exchange Act of 1934, except to the extent that Greater Bay Bancorp specifically incorporates the information contained in the report by reference, and shall not otherwise be deemed filed under such acts.

Executive compensation policies and practices

The Committee is responsible for establishing the overall philosophy on executive compensation, administering the Company’s executive compensation program, including incentive compensation and stock-based plans, and determining the compensation of the Chief Executive Officer and all other executive officers.

The overall objective of the Company’s philosophy on executive compensation is to ensure that executives are provided appropriate incentives and overall compensation in a manner that directly aligns pay with performance and supports both the short- and long-term interests of shareholders while effectively attracting

21

and retaining a high caliber of executive management talent. We engage a third-party independent compensation consulting firm to assist us with an assessment of the competitive market and to provide advice on current market practice.

The Compensation Committee believes that it is important for it to retain maximum flexibility in designing compensation programs that meet its stated objectives. In determining executive compensation, the Compensation Committee considers, among many factors, possible tax consequences to the Company. Tax consequences, including, but not limited to tax deductibility by the Company, are subject to many variables (such as changes in the tax laws and regulations or interpretations thereof and the timing and nature of various decisions by our executives regarding options and other rights) that are beyond the control of either the Compensation Committee or the Company. For all of the foregoing reasons, the Compensation Committee, while considering tax deductibility as one of its factors in determining compensation, will not limit compensation to those levels or types of compensation that will be deductible. The Compensation Committee will, of course, consider alternative forms of compensation that are consistent with its compensation goals and preserve deductibility.

Components of executive compensation

The key components of the executive compensation program are a competitive, market-based salary, an annual incentive plan, annual grants of long-term stock-based compensation in the form of stock options and/or restricted stock and employee benefits. In establishing each component of compensation, as well as the total compensation amount, we consider peer group data as provided by our independent consultants. For 2004, the peer company analyses included publicly traded regional banks similar to the Company in size and scope as well as published compensation survey data.

During fiscal 2004, the Compensation Committee, working with the independent compensation consulting firm, redesigned its approach to short-term and long-term performance-based incentive compensation. The assessment and redesign efforts were completed in January 2005 by a Subcommittee of the Compensation Committee and, subject to Shareholder approval, will be implemented for fiscal year 2005. As required by Section 162(m) of the Internal Revenue Code, the material terms of the new Executive Incentive Plan and Long Term Incentive Plan must be approved by the Company’s shareholders and Proposals 2 and 3 request that shareholders approve the terms of these new plans.

Fiscal 2004 Executive Compensation

Base Salaries

Base salaries for fiscal 2004 took into consideration the executive’s date in position, the responsibilities and accountabilities of the position and to the extent applicable and available, comparative data on comparable positions in the industry, the experience of the individual executive, and the individual and business unit performance of the executive based on the representations and recommendations of the Chief Executive Officer (except for his own compensation). The Committee generally pays base salaries with reference to the 75^th percentile or higher of the comparative data due to cost-of-living requirements in the San Francisco Bay Area and the experience level of the executives sought for the Company.

Annual Bonuses

In determining fiscal year 2004 bonuses for the executives named in the Summary Compensation Table, the Committee considered the following:

• the Company’s overall results measured against specific performance criteria;

• the executive’s individual performance and business unit results as represented by the Chief Executive Officer (except for his own performance);

• the executive’s contribution to the overall leadership of the Company;

22

• the executive’s target total cash compensation (base salary and bonus) in relation to internal peers and where available, to comparative data on comparable positions in the industry.

The Committee establishes annual incentive targets for executives such that, if specific performance goals are met or exceeded, the awards will be between the 75^th and 90^th percentiles of the competitive market. Although the Company did not achieve all of its financial goals for fiscal 2004, the Committee, in awarding bonuses to the named executives, recognized that certain accounting changes, one-time adjustments for historical corrections and short term investments for compliance-related activities (Sarbanes-Oxley) had a dilutive impact on the financial results for 2004, and that significant achievements in areas of internal controls, regulatory compliance, culture change and bank consolidation efforts as well as the retention of key executives had to be considered in awarding annual bonuses.

Long-term Compensation

For executive officers, a grant of options, restricted stock, or a combination of the two, are generally awarded annually in order to promote long-term value for our shareholders and equity ownership by our executives. In fiscal 2004, the Committee used the Amended and Restated 1996 Stock Option Plan to provide long-term incentive compensation to its key executives and other employees. All of the grants made under this plan in January 2004 vest ratably over a five-year period and have a term of ten years.

Employee Benefits

The Company offers its executives health, welfare and other benefits that are generally available to other employees. In addition, the Company has entered into individual agreements with certain executives and senior officers to provide a supplemental employee retirement plan (SERP). In 2004, the Compensation Committee elected to cease offering secular trusts as part of any new SERP agreement. In addition, beginning January 2005, the Compensation Committee approved a new SERP design, the 2005 Supplemental Executive Retirement Plan (“2005 SERP”) for new executives. The 2005 SERP is a defined benefit, which provides a benefit targeted at 50% of final average eligible compensation, with offsets for social security and other employer benefits, once the participant completes 25 or more years of service, or upon total and permanent disability or a change in control. There is no split-dollar life insurance agreement provided as a part of this new benefit. The Committee believes that the 2005 SERP design is an appropriate benefit for new executives and that it provides retention incentive and appropriate retirement compensation consistent with market practice.

Additionally, in 2004, the Company offered executives and certain senior officers a deferred compensation plan for the deferral of salary and bonuses by executive and certain senior officers, at the participant’s election. This plan provides participants with a return (positive or negative) that mirrors the performance of an array of investment funds from the 401(k) Plan. As of November 2004, this plan was frozen and subsequently amended in order to comply with new deferred compensation requirements under the American Jobs Creation Act of 2004.

Compensation to the Chief Executive Officer

In December 2003, the Company entered into an employment agreement with Mr. Scordelis to serve as President and Chief Executive Officer of the Company. As President and Chief Executive Officer, his base salary was set at $575,000, representing a 53% increase from his former salary of $375,000 as President and Chief Operating Officer of the Company. The new 2004 base salary was between the 25^th and 50^th percentile of the peer group salary data, which is lower than the compensation target, but was due to the level of his previous salary and his newness in the position.

At target levels of performance, Mr. Scordelis’ annual incentive bonus, as a percentage of base salary, is 80%. In determining Mr. Scordelis’ fiscal 2004 bonus award, we considered the Company’s financial results, but

23

necessarily recognized his significant leadership in directing the significant achievements and results in infrastructure investment/realignment and regulatory controls and compliance as well as his ability to attract highly qualified new talent to the executive team. As a result, Mr. Scordelis’ 2004 bonus of $300,000 (52.2% of base salary) as indicated in the Summary Compensation Table was 65% of his bonus award at target and 25% less than he received last year as the Company’s Chief Operating Officer.

In accordance with his December 2003 employment agreement, Mr. Scordelis received a grant of 50,000 options and a grant of 10,000 restricted shares of common stock in January 2004 and receives reimbursement for some country club and health club dues.

Executive Compensation Subcommittee

In 2004, the Committee elected a Subcommittee of the Compensation Committee in order to meet the “outside director” requirements under Section 162(m) of the Internal Revenue Code. Three of the four members of the Compensation Committee, Messrs. Gatto, Lindsay (retired in March 2005) and McLaughlin, met the criteria under Section 162(m) and were elected to this Subcommittee for the purpose of approving equity grants and designing and approving performance-based executive compensation for the Chief Executive Officer and the four other most highly compensated executives of the Company.

Respectfully submitted by the members of the Compensation Committee:

John M. Gatto, Chair

Arthur K. Lund

Glen McLaughlin

Donald H. Seiler

Proposal 2:  Approval of the Greater Bay Bancorp Long Term Incentive Plan

A.    General Summary

The Board of Directors has approved a new multi-year performance-based compensation plan for executives of the Company—the 2005 Long Term Incentive Plan (the “LTIP”), subject to shareholder approval. A copy of the LTIP is attached as Annex A. The objective of the LTIP is to reward executives for outstanding services provided to the Company. In addition, by linking a significant portion of the executive’s overall compensation to performance pools established under the LTIP, Greater Bay will be able to hold the executives accountable for their individual performance and Greater Bay’s corporate financial performance. Historically, Greater Bay has used stock options and restricted stock as its only long-term incentive for executives. The LTIP will provide a separate cash incentive that is not tied to the performance of Greater Bay’s stock, but instead is based on a fixed percentage of Greater Bay’s cumulative consolidated operating cash flow during specified performance periods.

The LTIP is also intended to provide income tax benefits to the Company. The LTIP is designed to qualify under Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162 (m)”) as a performance-based compensation plan. Under Section 162(m), compensation in excess of $1,000,000 paid to any of the chief executive officer and the four most highly compensated officers individually in a any year is not tax deductible by the Company unless the compensation is considered to be performance-based.

The LTIP is submitted to the shareholders for approval because under Section 162(m) shareholder approval of the plan is necessary in order for Greater Bay to qualify for the tax deduction for the performance-based compensation. Without shareholder approval, Greater Bay will not implement the LTIP and will not offer awards under the LTIP to executives. Greater Bay may pay other bonus compensation to executives that it will not be permitted to deduct as performance-based compensation, for federal income tax purposes to the extent an executive receives total compensation in excess of $1,000,000 in any year.

Greater Bay will continue to grant stock options and restricted stock under the 1996 Stock Option Plan. However, the Company desires to grant other types of performance awards in order to compete successfully for talented executives, to measure their performance by means other than the Company’s stock price, and to obtain advantageous tax and accounting treatment. Going forward, Greater Bay intends to structure incentive packages that include performance awards (like those under the LTIP), stock options, and restricted stock.

B.    LTIP—Plan Summary

Administration.    The LTIP will be administered by a subcommittee (the “Committee”) of the Company’s Compensation Committee consisting of at least three independent, non-employee directors. Members of the Committee must qualify as non-employee directors under Rule 16b-3 of the Securities Exchange Act of 1934, and as outside directors under Section 162(m).

Subject to the terms of the LTIP, the Committee has sole discretion to:

• select the executives who will receive performance awards;

• determine the terms and conditions of performance awards (subject to the maximum performance pool and performance award limitations); and

• interpret the provisions of the LTIP.

Performance Periods.    Performance awards will be determined over three-year performance periods beginning on January 1 of each year. The LTIP performance periods will be overlapping, with each calendar year after 2005 included in multiple performance periods. At the end of each year, beginning with 2007, the Committee will determine the amount of the LTIP pool and the extent to which performance awards are payable for the three-year performance period then ending.

29

Maximum Performance Pool.    Performance awards will be provided from a pool based on the Company’s consolidated operating cash flow, as determined under generally accepted accounting principles. The maximum amount that may be included in the pool and paid to all executives under the LTIP for any performance period is 1.0% of the Company’s cumulative operating cash flow for each year during that performance period.

Eligibility.    The Committee selects the executives to whom performance awards will be granted under the LTIP for each performance period. Executives selected for performance awards must hold officer or executive-level positions with Greater Bay, including the President and Chief Executive Officer and certain Executive Vice Presidents and Senior Vice Presidents nominated by the Chief Executive Officer and approved by the Committee.

Executives must hold an eligible officer or executive-level positions with the Company for at least one year during a performance period in order to receive a performance award payment under the LTIP for such performance period. Executives serving in such positions for less than the entire three-years of a performance period may receive a prorated award.

Types of Performance Awards.    In most cases, the performance awards under the LTIP will be paid in cash. However, the Committee may issue shares of Company Common Stock or restricted stock in lieu of cash. The payout of the performance award in shares of Company Common Stock or restricted stock will be in conjunction with the 1996 Stock Option Plan or its successor plan.

Determination of Performance Awards.    The amount of the performance awards paid to executives will be determined by the Committee for each performance period. The maximum pool of funds for payment of all performance awards under the LTIP for a performance period is an amount calculated as 1.0% of the Company’s cumulative operating cash flow for each year of the specific performance period. The Committee has the discretion to reduce the amount of the pool, based upon its determination of the Company’s or the executives’ performance during the performance period. The Committee, however, may not grant or payout performance awards that would exceed the maximum pool amount.

The Committee has discretion to determine the schedule for the payout of performance awards, including installments over a set period of time.

Maximum Individual Performance Awards.    Each executive participating in the LTIP for a performance period will be designated a share of the performance pool as a percentage of the Company’s operating cash flow to be specified by the Committee at the outset of the performance period. The amount of the LTIP performance award for any individual executive for any performance period may not exceed 0.4% of the Company’s cumulative operating cash flow for each year of the specific performance period, and such shares specified for all executives combined for any performance period may not exceed 1.0% of the Company’s cumulative operating cash flow for each year of the specific performance period. An executive’s performance award or share of the performance pool can be reduced on such basis as the Committee may determine, but cannot be increased as a result of a reduction in another executive’s performance award or for any other reason.

Vesting of Awards.    An executive’s LTIP performance award shall vest on such basis as the Committee shall determine while the executive performs services during the performance period. Vesting and payment of performance awards may be accelerated on such basis as the Committee shall determine upon the death or disability of the executive, a change in control of the Company, or upon termination of the executive’s employment, actually or constructively, without cause.

Nontransferability of Awards.    An executive’s LTIP performance award is payable only to such executive and cannot be transferred or assigned to anyone else.

30

Amendment and Termination of the LTIP.    The LTIP has no fixed expiration date and is intended to continue indefinitely. The Board of Directors or the Committee may amend or terminate the LTIP at any time and for any reason. However, amendments will be submitted for shareholder approval if necessary or appropriate to continue the LTIP’s compliance with Section 162(m).

Arbitration Requirement.    Any disputes under the LTIP or performance awards shall be submitted to arbitration with the Judicial Arbitration and Mediation Services, Inc. (“JAMS”) or the American Arbitration Association (“AAA”).

C.    Federal Tax Aspects

The following is a summary of the general federal income tax consequences to U.S. taxpayers and Greater Bay of performance awards granted under the LTIP. Tax consequences for any particular individual may be different.

Tax Effect for Executives.    A recipient of a performance award will not have taxable income at the time the performance award is granted. Instead, he or she will be subject to ordinary income tax on the amount received at the time the performance award is earned or paid. If the performance award is paid to the executive in Company common stock or restricted stock, the executive will be subject to taxation upon receipt of the stock or at such later time as any restrictions on the stock lapse.

Tax Effect for Greater Bay.    Greater Bay generally will receive a tax deduction for any ordinary income recognized by an executive from a performance award under the LTIP. Special rules limit the deductibility of compensation paid to the Company’s chief executive officer and its four most highly compensated officers. Under Section 162(m), the annual compensation paid to each of these executives may not be deductible to the extent that it exceeds $1,000,000. However, Greater Bay may preserve the deductibility of performance based compensation paid to the executives in excess of $1,000,000 if the conditions of Section 162(m) are met. These conditions include specifically defining the basis upon which the total performance-based compensation fund is measured and shareholder approval of such basis. The LTIP has been designed to provide a maximum pool from which performance awards are to be paid for each performance period that is 1.0% of the Company’s consolidated operating cash flow for the performance period. This maximum pool formula permits the Committee to grant awards that qualify as performance-based for purposes of satisfying the conditions of Section 162(m), provided that the Company’s shareholders approve the LTIP.

Shareholder approval of the LTIP is necessary for the plan to be implemented and for the performance-based compensation paid to the executives under the plan to be fully deductible by the Company for federal income tax purposes even if the total compensation paid by the Company to an executive exceeds $1,000,000 in any year. If shareholder approval is not given for the LTIP, the LTIP will not be implemented and any compensation in excess of $1,000,000 paid to an executive in any year, including base salary and any other compensation that does not meet the performance-based conditions of Section 162(m), will not be tax deductible by the Company. Approval of the LTIP requires the favorable vote of the majority of the votes cast at the Annual Meeting.

The Board recommends that you vote “FOR” approval of

the Greater Bay Bancorp 2005 Long Term Incentive Plan.

Proposal 3:  Approval of the Greater Bay Bancorp 2005 Executive Incentive Plan

A.    General Summary

The Board of Directors has approved a new annual performance-based compensation plan for executives of the Company—the 2005 Executive Incentive Plan (the “EIP”), subject to shareholder approval. A copy of the EIP is attached hereto as Annex B. The objective of the EIP is to reward executives for outstanding services provided to the Company. In addition, by linking a significant portion of the executive’s overall compensation to performance pools established under the EIP, Greater Bay will be able to hold the executives accountable for their individual performance and Greater Bay’s corporate financial performance. The EIP will provide an incentive that is based on a fixed percentage of the Company’s cumulative consolidated operating cash flow during each calendar year.

The EIP is also intended to provide income tax benefits to the Company. The EIP is designed to qualify under Section 162(m) as a performance-based compensation plan. Under Section 162(m), compensation in excess of $1,000,000 paid to any of the chief executive officer and the four most highly compensated officers individually in any year is not tax deductible by the Company unless the compensation is considered to be performance-based.

The EIP is submitted to the shareholders for approval because under Section 162(m) shareholder approval of the plan is necessary in order for Greater Bay to qualify for the tax deduction for the performance-based compensation. Without shareholder approval, Greater Bay will not implement the EIP and will not offer awards under the EIP to executives. Greater Bay may pay other bonus compensation to executives that it will not be permitted to deduct as performance-based compensation for federal income taxes purposes to the extent an executive receives total compensation in excess of $1,000,000 in any year.

Greater Bay will continue granting stock options and restricted stock under the 1996 Stock Option Plan. However, the Company desires to grant other types of performance awards in order to compete successfully for talented executives, to measure their performance by means other than the Company’s stock price, and to obtain advantageous tax and accounting treatment. Going forward, Greater Bay intends to structure incentive packages that include performance awards (like those under the EIP), stock options, and restricted stock.

B.    EIP—Plan Summary

Administration.    The EIP will be administered by the Committee consisting of at least three independent directors, who qualify as non-employee directors under Rule 16b-3 of the Securities Exchange Act of 1934 and as outside directors under Section 162(m).

Subject to the terms of the EIP, the Committee has sole discretion to:

• select the executives who will receive performance awards;

• determine the terms and conditions of performance awards (subject to the maximum performance pool and performance award limitations); and

• interpret the provisions of the EIP.

Performance Periods.    The performance periods will be single calendar years. At the end of each year, the Committee will determine the amount of the EIP pool and the extent to which performance awards are payable for such year.

Maximum Performance Pool.    Performance awards will be provided from a pool based on the Company’s consolidated operating cash flow, as determined under generally accepted accounting principles. The maximum amount that may be included in the pool and paid to all executives under the EIP for any year is 2.5% of the Company’s annual operating cash flow for such year.

32

Eligibility.    The Committee selects the executives to whom performance awards will be granted under the EIP for each year. Under the EIP, only the President, Chief Executive Officer and certain Executive Vice Presidents and Senior Vice Presidents nominated by the Chief Executive Officer and approved by the Committee are eligible.

Types of Performance Awards.    In most cases, the performance awards granted under the EIP will be paid out in cash. However, the Committee may issue shares of Company Common Stock or restricted stock in lieu of cash. The payout of the performance awards in shares of Company common stock or restricted stock will be in conjunction with the 1996 Stock Option Plan or its successor plan.

Determination of Performance Awards.    The amount of the performance awards to be paid out to executives will be determined by the Committee for each year. The maximum pool of funds for payments of all performance awards under the EIP for a given year is an amount calculated as 2.5% of the Company’s operating cash flow for such year. The Committee has the discretion to reduce the amount of the pool based upon its determination of the Company’s or the executives’ performance during the performance period. The Committee, however, may not grant or payout performance awards that would exceed the maximum pool amount.

The Committee has discretion to determine the schedule for the payout of performance awards.

Maximum Individual Performance Awards.    Each executive participating in the EIP for a given year will be designated a share of the performance pool as a percentage of the Company’s operating cash flow to be specified by the Committee at the outset of the year. The amount of the EIP performance award specified for any individual executive for any given year may not exceed 1.0% of the Company’s operating cash flow for such year, and such shares specified for all executives combined for any given year may not exceed 2.5% of the Company’s operating cash flow for such year. An executive’s performance award or share in the performance pool can be reduced on such a basis as the Committee may determine, but cannot be increased as a result of a reduction in another executive’s performance award or for any other reason.

Vesting of Awards.    An executive’s EIP performance award shall vest on such basis as the Committee shall determine while the executive performs services during the applicable year. Vesting and payment of performance awards may be accelerated on such basis as the Committee shall determine upon the death or disability of the executive, a change in control of the Company, or upon termination of the executive’s employment, actually or constructively, without cause.

Nontransferability of Awards.    An executive’s EIP performance award is payable only to such executive and cannot be transferred or assigned to anyone else.

Amendment and Termination of the EIP.    The EIP has no fixed expiration date and is intended to continue indefinitely. The Board of Directors or the Committee may amend or terminate the EIP at any time and for any reason. However, amendments will be submitted for shareholder approval if necessary or appropriate to continue the EIP’s compliance with Section 162(m).

Arbitration Requirement.    Any disputes under the EIP or the performance awards shall be submitted to arbitration with JAMS or the AAA.

C.    Federal Tax Aspects

The following is a summary of the general federal income tax consequences to U.S. taxpayers and Greater Bay for performance awards granted under the EIP. Tax consequences for any particular individual may be different.

Tax Effect for Executives.    A recipient of a performance award will not have taxable income at the time the performance award is granted. Instead, he or she will be subject to ordinary income tax on the amount

33

received at the time the performance award is earned or paid. If the performance award is paid to the executive in Company Common Stock or restricted stock, the executive will be subject to taxation upon receipt of the stock or at such later time as any restrictions on the stock lapse.

Tax Effect for Greater Bay.    Greater Bay generally will receive a tax deduction for any ordinary income recognized by an executive from a performance award. Special rules limit the deductibility of compensation paid to the Company’s chief executive officer and its four most highly compensated officers. Under Section 162(m), the annual compensation paid to each of these executives may not be deductible to the extent that it exceeds $1,000,000. However, Greater Bay may preserve the deductibility of performance-based compensation paid to the executives in excess of $1,000,000 if the conditions of Section 162(m) are met.

The EIP is designed to provide a maximum pool from which performance awards are to be paid for each performance period that is 2.5% of the Company’s consolidated operating cash flow for the performance period. This maximum pool formula permits the Committee to grant awards that qualify as performance-based for purposes of satisfying the conditions of Section 162(m), provided that the Company’s shareholders approve the EIP.

Shareholder approval of the EIP is necessary for the plan to be implemented and for the performance-based compensation paid to the executives under the plan to be fully deductible by the Company for federal income tax purposes, even if the total compensation paid by the Company to an executive exceeds $1,000,000 in any year. If shareholder approval is not given for the EIP, the EIP will not be implemented and any compensation in excess of $1,000,000 paid to an executive in any year, including base salary and any other compensation that does not meet the performance-based conditions of Section 162(m), will not be tax deductible by the Company. Approval of the EIP requires the favorable vote of the majority of the votes cast at the Annual Meeting.

The Board recommends that you vote “FOR” approval

of the Greater Bay Bancorp 2005 Executive Incentive Plan.

Proposal 4:  Ratify Selection of Independent Registered Public Accounting Firm for 2005

Principal Auditor Fees and Services

The Audit Committee has appointed PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2005, and shareholders are being asked to ratify the appointment. PricewaterhouseCoopers LLP, our independent registered public accounting firm for the year ended December 31, 2004 and December 31, 2003, performed audit services for 2004 and 2003 which included the examination of the consolidated financial statements and services related to filings with the SEC. All professional services rendered by PricewaterhouseCoopers LLP during 2004 were furnished at customary rates and terms. Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting and will be available to respond to appropriate questions from shareholders. If you do not ratify the appointment, the Audit Committee will reconsider the appointment. However, even if you ratify the appointment, the Audit Committee may appoint a new independent registered public accounting firm at any time during the year if it believes that such a change would be in the best interests of Greater Bay and its shareholders.

All audit and non-audit services to be performed by PricewaterhouseCoopers LLP require pre-approval by the Audit Committee or its Chairman provided that the Chairman reports any decisions to pre-approve such audit related or non-audit services and fees to the full Audit Committee at its next regular meeting.

In determining the independence of PricewaterhouseCoopers LLP, the Audit Committee considered whether the provision of non-audit services is compatible with maintaining that independence.

The Board recommends that you vote “FOR” ratification of the selection of

PricewaterhouseCoopers LLP as our Independent Registered Public Accounting Firm for 2005.

Proposal 5:  Shareholder Proposal to Restrict the Company’s Use of Preferred Stock

We have received a shareholder proposal from a shareholder who owns of record 3,153 shares of our Common Stock who has advised us that he plans to introduce the following resolution at the Annual Meeting:

“That the shareholders of GREATER BAY BANCORP now request its Board of Directors to take the steps necessary to amend its articles of incorporation and by-laws to require that any authorized but unissued Preferred Stock be used only for the purposes of increasing capital or making bona-fide arms-length acquisitions and not be used as a “POISON PILL” to prevent the acquisition of Greater Bay Bancorp.”

The reasons given by the shareholder are quoted verbatim below. The Board of Directors of Greater Bay disagrees with the adoption of the resolution proposed below and asks shareholders to read through the response which follows the shareholder proposal below.

35

STATEMENT

The proponent of this proposal notes the “fine print” on page 70 of the joint proxy statement of the merger of SJNB Financial Corp. which outlines the possible issuance of 10,500,000 shares of Series A Preferred Stock and other anti-takeover provisions including a super-majority requirement.

THIS IS A POISON PILL!

Page 38 of last year’s proxy statement notes: “The Company’s Restated Articles of Incorporation and by-laws contain provisions which may deter a change in control, including provisions for Series A Preferred Stock to be used for our shareholder rights plan, preferred stock which may be issued on such terms as the Board of Directors shall determine....”

OUCH!

The proponent of this proposal is a professional investor who realizes the best interests of shareholders of Greater Bay Bancorp may be its merger into another bank holding company which could bring better management to our shareholders.

The possibility of a merger has been acknowledged by the Board of Directors but a “poison pill” could prevent a reputable, ethical, and profitable entity from acquiring Greater Bay Bancorp.

Moreover, the grant of the exercise of the rights could be costly, or even unaffordable, to many owners. If granted and exercised, a costly clean-up could prevail in the aftermath.

Shareholders should judge a proposed acquisition on its merits and value—not, the whims of management making their decision.

Accountability, performance, and achievement are issues which do not need “weather stripping” to prevent a change of control which, under some circumstances, could improve the long term rewards for shareholders.

A similar proposal was before the shareholders of Wells Fargo & Company in its 2002 annual meeting where it was approved by shareholders. The Board of Directors then reconsidered its position and rescinded its “poison pill” without cost to the shareholders.

If you agree, please vote “FOR” this proposal. Unmarked proxies will be automatically voted “against” it.

The Board of Directors unanimously recommends a vote “AGAINST” this

proposal for the following reasons:

Directors’ Statement in Opposition

The proposal requests that the Board take actions necessary to require that any unissued preferred stock not be used for shareholder rights plans. The Board recommends a vote AGAINST this proposal.

The Proposal would inappropriately limit the ability of the Company to issue preferred stock

The proposal seeks to limit the availability of preferred stock for the narrow purpose of increasing capital or making acquisitions and specifically to prohibit the use of preferred stock for shareholder rights plans. We believe this would severely hinder the ability of the Board to protect shareholder value in the face of a hostile takeover whereby an acquirer might seek to acquire the Company at a price substantially below its value. This

36

proposal might result in the shareholders getting less than what the Board could negotiate with adequate takeover defenses in place.

Preferred stock can also be used for a number of other legitimate purposes, besides raising capital and making acquisitions. Other purposes that would benefit shareholder interests include strategic partnerships, stock splits/dividends/distributions, and/or employee compensation. We believe limiting the use of preferred stock to just raising capital and acquisitions is short-sighted, because it reduces your Board’s flexibility in issuing preferred stock, is contrary to your Board’s fiduciary duties and not in the best interests of all shareholders.

Background on current Rights Plan

In 1998, your Board adopted a shareholder rights plan, or the Rights Plan, designed to maximize long-term shareholder value and to protect shareholders from improper takeover tactics and takeover bids that are not fair to all shareholders. The Rights Plan expires in November 2008.

In accordance with the Rights Plan, preferred share purchase rights were distributed as a dividend at the rate of one right for each common share held of record as of the close of business on November 28, 1998. The rights, which are not immediately exercisable, entitle the holders to purchase one one-hundredth of a share of Series A Preferred Stock at a price of $145.00 (subject to adjustment) upon the occurrence of certain triggering events. In the event of an acquisition not approved by the Board, each right enables its holder (other than the acquirer) to purchase the Preferred Stock at 50% of the market price. Further, in the event the Company is acquired in an unwanted merger or business combination, each right enables the holder to purchase shares of the acquiring entity at a similar discount. Under certain circumstances, the rights may be exchanged for Company common shares. The Board may, in its sole discretion, redeem the rights at any time prior to any of the triggering events.

The rights can be exercised and separate rights certificates distributed only if any of the following events occur: acquisition by a person of 10% or more of our common shares; a tender offer for 10% or more of our common shares; or ownership of 10% or more of our common shares by a shareholder whose actions are likely to have a material adverse impact on the Company or shareholder interests. The rights trade automatically with the common shares. The rights are not deemed by the Board of Directors to be presently exercisable.

Similar plans have been adopted by over 2,000 companies, including about half of the Standard & Poor’s 500.

The Rights Plan benefits shareholders

The Board believes the action requested is ill-advised since it would prohibit the ability of the Company to use preferred stock for shareholder rights plans under any circumstances, would be unduly restrictive, and contrary to the best interests of the Company’s shareholders. The Company’s Rights Plan is an important tool that enables the Board to maximize shareholder value in the event of a proposed acquisition of control of the Company. The Rights Plan also allows the Board to protect the Company and its shareholders from unfair and coercive takeover tactics, such as a partial or two-tier tender offers, a “creeping acquisition” or other tactics that the Board believes are unfair to the Company’s shareholders.

The Rights Plan is not intended to prevent a takeover of the Company, nor does the Rights Plan change or diminish the fiduciary obligations of the Company’s Board. The Rights Plan strengthens the ability of the Board, 8 of whose 12 current members are considered independent under current Nasdaq rules, to fulfill its fiduciary duties under California law. Prior to the acquisition of 10% of the Company’s common shares by an acquirer, the Board has the power to redeem the rights issued under the Rights Plan and thereby remove the impediment to the completion of an acquisition of the Company. A prospective acquirer seeking to persuade the Board to redeem the rights may propose a higher takeover price, an offer for all shares rather than a partial offer or better takeover terms than would be proposed if no rights plan were in place.

37

The Board believes it is in the best position to negotiate on behalf of all shareholders, evaluate the adequacy of any potential offer, and seek a higher price if there is to be a sale of the Company. In summary, the Rights Plan allows your Board a greater period to evaluate offers, explore other alternatives and take the necessary steps to maximize shareholder value. Without the protection of the Rights Plan, your Board would lose important bargaining power in negotiating the transaction with a potential acquirer or pursuing a potentially superior alternative.

Studies focused on rights plans demonstrate that rights plans increase shareholder value

Merger and acquisition activity over the last ten years shows that rights plans neither prevent unsolicited offers from occurring nor prevent companies from being acquired at prices that are fair and adequate to shareholders. In fact, a study by J.P. Morgan published in 2001, analyzing 397 acquisitions of U.S. public companies from 1997 to 2000 where the purchase price exceeded $1 billion, found that companies with rights plans in place received a median premium of 35.9% compared to 31.9% for companies without a rights plan. A study published by Georgeson & Company, a nationally recognized proxy solicitation firm, of takeover premiums during the period from 1992 to 1996 of 319 takeover transactions over $250 million also concluded that premiums paid to acquire target companies with shareholder rights plans in place at least six months prior to the first bid, were on the average, about eight percentage points higher than premiums paid for target companies that did not have such plans. In addition, the Georgeson study concluded that the presence of a rights plan did not increase the likelihood of the defeat of a hostile takeover bid or the withdrawal of a friendly bid and that rights plans did not reduce the likelihood that a company would become a takeover target.

Thus, empirical evidence suggests that rights plans serve their principal objectives:

• protection against inadequate offers and abusive tactics; and

• increased bargaining power resulting in higher value for shareholders.

Indeed, many companies with rights plans have received unsolicited takeover proposals and have redeemed their rights after their board of directors concluded that the offer, as negotiated by such board of directors, adequately reflected the intrinsic value of the company and was fair and equitable to all shareholders.

Some recent examples of hostile takeovers increasing bids where the target had a rights plan in place include PeopleSoft-Oracle Corporation and in the banking industry, Central Pacific Financial Corp—CB Bancshares, Inc. Based on publicly available information provided by the companies, shareholders eventually received significant increases from the initial offers:

Target-Acquirer	Initial Per Share Offer Price		Eventual Negotiated Per Share Price		Percentage Increase
PeopleSoft-Oracle	$	16.00	$	26.50	65	%
CB Bancshares—Central Pacific Financial Corp.	$	68.39	$	91.83	34	%

We acknowledge that it is difficult to determine just how much impact the shareholder rights plans had on the eventual price; however, we do believe these rights plans had a significant impact on the ability of the target boards to negotiate what they believe was a fair price to their shareholders.

The Wells Fargo Proposal was not the same as this Proposal

The Proponent asserts that a similar proposal was considered by Wells Fargo shareholders. This is not true—the Wells Fargo shareholder proposal was as follows:

That the shareholders of WELLS FARGO & COMPANY, assembled in person and by proxy in an annual meeting, request the Board of Directors to eliminate or rescind the “Rights” which are more commonly known as a “poison pill” and not to extend such “Rights” after the expiration of the current “Rights.

38

The Proponent should know the difference, since he made the Wells Fargo proposal. The 2002 Wells Fargo proposal merely addressed the then-current Wells Fargo shareholder rights plan and did not seek limitations on the use of preferred stock.

The Board must perform its fiduciary obligations

The Board believes that the adoption and maintenance of the Rights Plan is appropriately within the scope of responsibilities of the Board, acting on behalf of all shareholders. The adoption of such a Plan accords with the Board’s responsibilities for the management of the Company’s affairs and the issuance of securities. To cancel or redeem the Rights Plan now, in the absence of an acquisition proposal, would remove an important tool that the Board should have for the protection of shareholders and would leave shareholders vulnerable to an unsolicited and potentially coercive and unfair takeover offer. In the Board’s view, this would eventually reduce long-term value for shareholders. The Board believes that any decision to cancel or redeem the Rights Plan should be made by the Board in the context of a specific acquisition proposal.

In any event, the Company will continue to evaluate the Rights Plan and will carefully consider the results of the vote on the proposal, the advantages and disadvantages of such plan and the state of the then current corporate governance debate on rights plans generally. At this time your Board has decided to retain the Rights Plan.

The recommendation against the proposal is based on the Board’s belief that:

• Your Board should not be limited in its ability to issue preferred stock when it determines such issuance to be in the best interests of the shareholders,

• Rights plans are an effective tool to protect shareholders against abusive and unfair takeover tactics thereby enabling the Board to maximize shareholder value in the event of a takeover attempt,

• The ability to use preferred stock in establishing or maintaining a rights plan is an essential and proven tactic to address hostile takeovers and to preserve and maximize long-term shareholders value, and

• It is inappropriate and unwise to limit the scope of the Board’s extensive experience, business judgment and flexibility to act in the best interests of the shareholders.

Accordingly, your Board unanimously recommends that you vote AGAINST this proposal. Unless otherwise specified by the shareholder, the Board intends the accompanying proxy to be voted against this proposal.

The affirmative vote of the holders of a majority of the shares of the Company’s Capital Stock present in person or represented by proxy at the Annual Meeting and entitled to vote is necessary for approval of the shareholder proposal. Signed proxies will be voted against the shareholder proposal unless otherwise specified.

The name, address and telephone number of the proponent of the shareholder proposal are: Gerald R. Armstrong, 820 Sixteenth Street, No. 705, Denver, Colorado 80202-3227, (303) 355-1199.

The Board of Directors recommends that you vote “AGAINST” approval

of the proposal regarding the restriction on the Company’s use of Preferred Stock.

OTHER BUSINESS

We know of no other business which will be presented for consideration at the Annual Meeting other than as stated in the Notice of Annual Meeting. If, however, other matters are properly brought before the meeting, it is the intention of the persons named as proxies in the enclosed proxy card to vote the shares represented thereby in accordance with their best judgment and in their discretion, and authority to do so is included in the proxy.

3.    Performance Awards

3.1  Establishment of Performance Awards.    Any Executive selected by the Committee may be granted one or more Performance Awards. All Performance Awards under this Plan shall be made based upon the Section 162(m) Pool. Individual Performance Awards shall be determined by the Committee, at its discretion. In no event may the aggregate value of individual Performance Awards exceed the maximum value of the Section 162(m) Pool.

3.2  Establishment of LTIP Pool.    The LTIP Pool shall be established by the Committee for each Performance Period as an amount that is equal to or less than the Section 162(m) Pool. In making any reductions to the Section 162(m) Pool to establish the LTIP Pool, the Committee may consider such factors as it determines are relevant for the Performance Period.

3.3  Additional Limitations.    Notwithstanding any other provision of the Plan, any Performance Award that is granted to a Participant and is intended to constitute qualified performance-based compensation shall be

A-3

subject to any additional limitations set forth in Section 162(m) of the Code (including any amendment to Section 162(m) of the Code) or any regulations or rulings issued thereunder that are requirements for qualification as qualified performance-based compensation as described in Section 162(m)(4)(C) of the Code, and the Plan shall be deemed amended to the extent necessary to conform to such requirements.

3.4  Maximum Individual Performance Award.    Notwithstanding any other provision of the Plan, no Executive shall receive a Performance Award for any Performance Period in excess of four-tenths of one percent (0.4%) of the cumulative Operating Cash Flow for the specific Performance Period for which the Performance Award is granted.

3.5  Effect of Mid-Year Commencement of Service.    If an Executive becomes eligible to participate in the Plan after the commencement of a Performance Period, the Committee may grant the Executive a Performance Award for such Performance Period that is proportionately adjusted based on the period of time during the Performance Period that the Executive is a Participant. In order to receive such a prorated Performance Award, the Executive must hold a qualifying Executive position for at least one (1) year during the applicable Performance Period.

3.6  Unpaid Leave of Absence.    If a Participant takes an unpaid leave of absence from the Company or a Subsidiary, at the discretion of the Committee, the Performance Award may be proportionately adjusted based on the period of Participant’s actual service during the Performance Period.

3.7  Committee Discretion to Determine Performance Awards.    The Committee has the sole discretion to determine the standard or formula pursuant to which reductions are to be made to the Section 162(m) Pool in establishing the LTIP Pool, the calculation of each Participant’s Performance Award (in accordance with Sections 3.1 and 3.2 of the Plan) from the LTIP Pool, whether all or any portion of the amount so calculated will be paid, and the specific amount (if any) to be paid to each Participant, subject in all cases to the terms, conditions and limits of the Plan and of any other written commitment authorized by the Committee. The Committee has the sole discretion to reduce an Executive’s Performance Award. The Committee may not, however, increase an Executive’s Performance Award based upon the reduction of another Executive’s Performance Award or otherwise. The Committee may at any time establish (and, once established, rescind, waive or amend) additional conditions and terms of payment of Performance Awards as it may deem desirable in carrying out the purposes of the Plan and may take into account such other factors as it deems appropriate in administering any aspect of the Plan. The Committee may not, however, increase the Section 162(m) Pool or the maximum amount permitted to be paid to any Executive under Section 3.4 of the Plan for any Performance Period.

3.8  Committee Certification.    No Executive shall receive any payment under the Plan unless the Committee has certified, by resolution or other appropriate action in writing, that the amount thereof has been accurately determined in accordance with the terms, conditions and limits of the Plan and that the material terms previously established by the Committee or set forth in the Plan were in fact satisfied.

3.9  Time of Payment; Deferred Amounts.    Any Performance Award granted by the Committee under the Plan shall be paid as soon as practicable (generally within seventy-five (75) days), following the Committee’s determinations under this Section 3.9 and the certification of the Committee’s findings under Section 3.8. At the Committee’s discretion, subject to compliance with Section 409A of the Code, payments to the Executive may be made on a structured basis so long as the payment dates are fixed. Any such payment shall be in cash or cash equivalent or in such other form of equal value on such payment date (including Shares, Restricted Stock, or share equivalents as contemplated by Section 3.10 as the Committee may approve or require, subject to applicable withholding requirements (as provided in Section 3.11). Notwithstanding the foregoing, the Committee, in its sole discretion (but subject to compliance with Section 162(m), to compliance with Section 409A of the Code, and to any prior written commitments and to any conditions consistent with Sections 3.10, 5.3 and 7.10 that it deems appropriate), provide to Participants the opportunity to elect to defer the payment of any Performance Award under a nonqualified deferred compensation plan.

A-4

3.10  Share Payouts of Performance Award.    Any Share, Restricted Stock or Share-related stock unit payout under a Performance Award shall be pursuant to a combined Performance Award under the Plan and the Stock Plan. The number of Shares, Restricted Stock, or stock units awarded in lieu of all or any portion of a Performance Award shall be equal to the largest whole number of Shares which have an aggregate fair market value no greater than the amount of cash otherwise payable as of the date the cash payment of the Performance Award would have been made. For this purpose, “fair market value” shall have the meaning set forth in the Stock Plan. Any such Shares, Restricted Stock, or stock units (or similar rights) shall thereafter be subject to adjustments for changes in corporate capitalization as provided in the Stock Plan.

3.11  Tax Withholding.    The Company shall withhold from any amounts payable under this Plan, or from any other compensation payable to the Participant, any and all federal, state and local income taxes, the Participant’s share of FICA and other employment taxes, and any other taxes that are required to be withheld from such payment under applicable law.

4.    Vesting and Termination of Performance Awards

4.1  Vesting or Termination.    Except as otherwise set forth in the Plan, in the event the Participant’s employment with the Company and its Subsidiaries terminates during a Performance Period or thereafter prior to payment of Performance Awards relating thereto, each Performance Award shall be vested or shall terminate on such terms and conditions as the Committee shall establish with respect to the Performance Award.

4.2  Termination of Employment for Cause.    If a Participant’s employment with the Company or a Subsidiary is terminated for Cause or if a Participant engages in misconduct defined as Cause either before voluntarily terminating employment or after terminating employment, any Performance Award held by such Participant shall terminate immediately upon the Company giving notice to the Participant either that the Participant has been terminated for Cause or that the Participant has engaged in misconduct defined as Cause. The Committee shall be the sole judge of whether the Participant’s employment is terminated for Cause or the Participant has engaged in misconduct defined as Cause.

4.3  Termination of Employment due to Death and Disability.    If a Participant’s employment with the Company or a Subsidiary is terminated due to death or Disability, then the Participant shall be eligible to receive payment of a prorated Performance Award within ninety (90) days of the termination date, or such shorter or longer time period as may be determined by the Committee, but only to the extent that the Performance Award was earned on the termination date. The prorated value of the Performance Award shall be calculated based upon the target value of the individual Performance Award, rather than the LTIP Pool (as the LTIP Pool may not be established prior to the payment date.)

4.4  Termination of Employment due to Retirement.    If a Participant’s employment with the Company or a Subsidiary is terminated due to retirement after attaining age sixty-two (62) years, then the Participant shall be eligible to receive a prorated Performance Award based on actual performance at the end of the Performance Period, or such shorter period as may be determined by the Committee. In order to receive such a prorated Performance Award, the Executive must have held a qualifying Executive position for at least one (1) year during the applicable Performance Period.

5.    Administration

5.1  Powers of the Committee.    The Committee shall have the sole authority to establish the LTIP Pool, determine the Executives who will participate in and receive Performance Awards under the Plan, and, subject to the terms of the Plan, the amount of Restricted Stock or Shares under such Performance Awards, and the time or times at which and the form and manner in which Performance Awards will be paid (which may include elective or mandatory deferral alternatives), and shall otherwise be responsible for the administration of the Plan, in accordance with its terms. The Committee shall have the authority to construe and interpret the Plan (except as

A-5

otherwise provided herein) and any agreement or other document relating to any Performance Awards under the Plan, may adopt rules and regulations governing the administration of the Plan, and shall exercise all other duties and powers conferred on it by the Plan, or which are incidental or ancillary thereto.

5.2  Requisite Action.    A majority (but not fewer than two) of the members of the Committee shall constitute a quorum. The vote of a majority of those present at a meeting at which a quorum is present or the unanimous written consent of the Committee shall constitute action by the Committee.

5.3  Express Authority (and Limitations on Authority) to Change Terms and Conditions of Performance Awards; Acceleration of Payment.    Without limiting the Committee’s authority under other provisions of the Plan, but subject to any express limitations of the Plan and compliance with Section 162(m), the Committee shall have the authority to accelerate a Performance Award and to waive restrictive conditions for a Performance Award, in such circumstances as the Committee deems appropriate. In addition, and notwithstanding anything elsewhere in the Plan to the contrary, the Committee shall have the authority to provide under the terms of a Performance Award that payment or vesting shall be accelerated upon the death or disability of a Participant, a Change in Control of the Company, or upon termination of the Participant’s employment without Cause or as a constructive termination, as and in the manner provided by the Committee. In no event, however, may the Committee modify Performance Awards such that the limitations on Performance Award values set forth in Sections 3.1, 3.3, and 3.4 are exceeded.

6.    Amendment, Suspension or Termination

6.1  Amendment, Suspension or Termination of Plan.    The Board or the Committee may from time to time amend, suspend, or terminate in whole or in part, and if suspended or terminated, may reinstate, any or all of the provisions of the Plan. Notwithstanding the foregoing, no amendment shall be effective without Board and/or shareholder approval if such approval is necessary to comply with the applicable provisions of Section 162(m).

7.    General Provisions

7.1  No Right to Performance Awards or Continued Employment.    Neither the establishment of the Plan nor the provision for or payment of any amounts hereunder nor any action of the Company (including, for purposes of this Section 7.1, any predecessor or subsidiary), the Board or the Committee in respect of the Plan shall be held or construed to confer upon any person any legal right to receive, or any interest in, a Performance Award or any other benefit under the Plan, or any legal right to be continued in the employ of the Company. The Company expressly reserves any and all rights to discharge an Executive in its sole discretion, without liability of any person, entity or governing body under the Plan or otherwise. Nothing in this Section 7.1, however, is intended to adversely affect any express independent right of any person under a separate employment agreement. Notwithstanding any other provision hereof and notwithstanding the fact that required criteria have been attained and/or the individual maximum amounts hereunder have been calculated, the Company shall have no obligation to pay any Performance Award hereunder nor to pay the maximum amount so calculated or any prorated amount based on service during the period, unless the Committee otherwise expressly provides by written contract or other written commitment.

7.2  Subsequent Performance Awards.    The designation of a Participant for a Performance Period shall not in any manner entitle the Participant to receive a Performance Award for the Performance Period. Moreover, designation of a Participant for a particular Performance Period shall not require designation of such Participant for any subsequent Performance Period, and designation of one Participant for any Performance Period shall not require designation of any other Participant in such Performance Period or in any other Performance Period.

7.3  Discretion of Company, Board and Committee.    Any decision made or action taken by the Company or by the Board or by the Committee arising out of or in connection with the creation, amendment, construction, administration, interpretation, and effect of the Plan shall be within the absolute discretion of such entity and shall be conclusive and binding upon all persons. No member of the Board or the Committee shall have any liability for actions taken or omitted under the Plan by the member or any other person.

A-6

7.4  Arbitration.    All claims, disputes and other matters in question arising out of or relating to this Plan shall be resolved by binding arbitration before an arbitrator, selected by the mutual agreement of the parties, from the Judicial Arbitration and Mediation Services, Inc. (“JAMS”), in San Francisco, California. In the event JAMS is unable or unwilling to conduct the arbitration provided for under the terms of this paragraph, or has discontinued its business, the parties agree that an arbitrator, selected by the mutual agreement of the parties, from the American Arbitration Association (“AAA”), in San Francisco, California, shall conduct the binding arbitration referred to in this paragraph. Notice of the demand for arbitration shall be filed in writing with the other party to the dispute and with JAMS (or AAA, if necessary). In no event shall the demand for arbitration be made after the date when institution of legal or equitable proceedings based on such claim, dispute or other matter in question would be barred by the applicable statute of limitations. The arbitration shall be subject to commercial rules and procedures used or established by JAMS, or if there are none, the commercial rules and procedures used or established by AAA. Notwithstanding anything to the contrary in the JAMS (or AAA) rules and procedures, the arbitration shall provide for (i) written discovery and depositions adequate to give the parties access to documents and witnesses that are essential to the dispute and (ii) a written decision by the arbitrator that includes the essential findings and conclusions upon which the decision is based. Subject to Section 7.5 below, the parties shall bear their own costs and attorneys’ fees incurred in conducting the arbitration, and shall split equally the fees and administrative costs charged by the arbitrator and JAMS (or AAA) unless required otherwise by applicable law. Any award rendered by JAMS (or AAA) shall be final and binding upon the parties, and as applicable, their respective heirs, Beneficiaries, legal representatives, agents, successors and assigns, and may be entered in any court having jurisdiction thereof. Any arbitration hereunder shall be conducted in Palo Alto, California, unless otherwise agreed to by the parties.

7.5  Attorneys Fees.    In the event of any arbitration or litigation concerning any controversy, claim, or dispute arising out of or relating to this Plan, the prevailing party shall be entitled to recover from the non-prevailing party reasonable expenses, attorneys’ fees and costs incurred in connection therewith or in the enforcement or collection of any judgment or award rendered therein. The “prevailing party” means the party determined by the arbitrator(s) or court, as the case may be, to have most nearly prevailed, even if such party did not prevail in all matters, not necessarily the one in whose favor a judgment is rendered.

7.6  No Funding of Plan.    The Company shall not be required to fund or otherwise segregate any cash or any other assets which may at any time be paid to Participants under the Plan. The Plan shall constitute an “unfunded” plan of the Company. The Company shall not, by any provisions of the Plan, be deemed to be a trustee of any property, and any rights of any Participant or former Participant shall be no greater than those of a general unsecured creditor or shareholder of the Company, as the case may be.

7.7  Non-Transferability of Benefits and Interests.    Except as expressly provided by the Committee, no benefit payable under the Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, or charge, and any such attempted action shall be void and no such benefit shall be in any manner liable for or subject to debts, contracts, liabilities, engagements or torts of any Participant or former Participant. This Section 7.7 shall not apply to an assignment of a contingency or payment due (i) after the death of an Participant to the deceased Participant’s legal representative or beneficiary or (ii) after the disability of a Participant to the disabled Participant’s personal representative.

7.8  Law to Govern.    All questions pertaining to the construction, regulation, validity and effect of the provisions of the Plan shall be determined in accordance with the laws of the State of California.

7.9  Non-Exclusivity.    The Plan does not limit the authority of the Company, the Board, or the Committee, or any Subsidiary of the Company to grant awards or authorize any other compensation to any person under any other plan or authority, including, without limitation, the issuance of Shares, Restricted Stock or Share-related stock units or any other awards under the Stock Plan.

7.10  Section 162(m) Conditions; Bifurcation of Plan.    It is the intent of the Company that the Plan and Performance Awards made hereunder satisfy and be interpreted in a manner, that, in the case of Participants who

A-7

are persons whose compensation is subject to Section 162(m), satisfies any applicable requirements as performance-based compensation. Any provision, application or interpretation of the Plan inconsistent with this intent to satisfy the standards in Section 162(m) of the Code shall be disregarded. Notwithstanding anything to the contrary in the Plan, the provisions of the Plan may at any time be bifurcated by the Board or the Committee in any manner so that certain provisions of the Plan or any Performance Award intended (or required in order) to satisfy the applicable requirements of Section 162(m) are only applicable to persons whose compensation is subject to Section 162(m).

7.11  Indemnification.    To the extent allowable pursuant to applicable law, each member of the Committee or of the Board shall be indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action or failure to act pursuant to the Plan and against and from any and all amounts paid by him or her in satisfaction of judgment in such action, suit, or proceeding against him or her, provided he or she gives the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled pursuant to the Company’s Certificate of Incorporation or bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

7.12  Titles and Headings.    The titles and headings of the sections in the Plan are for convenience of reference only and, in the event of any conflict, the text of the Plan, rather than such titles or headings, shall control.

8.    Effective Date

8.1  Effective Date of the Plan.    The Plan shall be effective as of January 1, 2005, subject to the approval of the shareholders of the Company.

3.    Administration of the Plan

3.1 Powers of the Committee.    The Committee shall have the sole authority to establish and administer the EIP Pool, determine the Executives who will participate in and receive Awards under the Plan, and, subject to the terms of the Plan, establish the amount of Restricted Stock or Shares under such Awards, and the time or times at which and the form and manner in which Awards will be paid (which may include elective or mandatory deferral alternatives), and shall otherwise be responsible for the administration of the Plan, in accordance with its terms. The Committee shall have the authority to construe and interpret the Plan (except as otherwise provided herein) and any agreement or other document relating to any Awards under the Plan, may adopt rules and regulations governing the administration of the Plan, and shall exercise all other duties and powers conferred on it by the Plan, or which are incidental or ancillary thereto.

3.2 Requisite Action.    A majority (but not fewer than two) of the members of the Committee shall constitute a quorum. The vote of a majority of those present at a meeting at which a quorum is present or the unanimous written consent of the Committee shall constitute action by the Committee.

3.3 Express Authority (and Limitations on Authority) to Change Terms and Conditions of Awards; Acceleration of Payment.    Without limiting the Committee’s authority under other provisions of the Plan, but subject to any express limitations of the Plan and compliance with Section 162(m), the Committee shall have the authority to accelerate an Award and to waive restrictive conditions for an Award, in such circumstances as the Committee deems appropriate. In addition, and notwithstanding anything elsewhere in the Plan to the contrary, the Committee shall have the authority to provide under the terms of an Award that payment or vesting shall be accelerated upon the death or disability of a Participant, a Change in Control of the Company, or upon termination of the Participant’s employment without cause or as a constructive termination, as and in the manner provided by the Committee. In no event, however, may the Committee modify Awards such that the limitations on Award values set forth in 4.1 and 4.3 are exceeded.

B-3

4.    Awards

4.1 Provision for Awards.    All Awards under this Plan shall be based upon the Section 162(m) Pool. Individual Awards shall be determined by the Committee, at its discretion. In no event may the aggregate value of individual Awards exceed the maximum value of the Section 162(m) Pool.

4.2 Establishment of EIP Pool.    The EIP Pool shall be established by the Committee for each Performance Period as an amount equal to or less than the Section 162(m) Pool. In making any reductions to the Section 162(m) Pool to establish the EIP Pool, the Committee may consider such factors as it determines are relevant for the Performance Period.

4.3 Maximum Individual Award.    Notwithstanding any provision hereof, no Executive shall receive an Award for any one Performance Period in excess of one percent (1%) of the Company’s Operating Cash Flow for the specific Performance Period during which the Award is granted. The foregoing limits shall be subject to adjustments consistent with Section 3.3 in the event of acceleration or deferral.

4.4 Selection of Participants.    For each Performance Period, the Committee shall determine those Executives who will participate in the Plan.

4.5 Effect of Mid-Year Change in Executive Status.    If services as an Executive cease after the commencement of a Performance Period, but the Participant remains employed with the Company, the Committee may grant a Bonus that is proportionately adjusted based on the period of time during the Performance Period that the Executive is a Participant; the amount of any Bonus paid to such Participant shall not exceed that proportionate amount of the applicable maximum individual Award under Section 4.3. In order to be eligible to participate in the Plan, the Executive must be employed in an Executive position for at least ninety (90) days during the Performance Period.

4.6 Committee Discretion to Determine Bonuses.    The Committee has the sole discretion to determine the standard or formula pursuant to which reductions are to be made to the Section 162(m) Pool in establishing the EIP Pool, the calculation each Participant’s Bonus (in accordance with Sections 4.1, 4.2 and 4.3) from the EIP Pool, whether all or any portion of the amount so calculated will be paid, and the specific amount (if any) to be paid to each Participant, subject in all cases to the terms, conditions and limits of the Plan and of any other written commitment authorized by the Committee. The Committee has the sole discretion to reduce an Executive’s Bonus. The Committee may not, however, increase an Executive’s Bonus based upon the reduction of another Executive’s Bonus or otherwise. The Committee may at any time establish (and, once established, rescind, waive or amend) additional conditions and terms of payment of Bonuses (including but not limited to the achievement of other financial, strategic or individual goals, which may be objective or subjective) as it may deem desirable in carrying out the purposes of the Plan and may take into account such other factors as it deems appropriate in administering any aspect of the Plan. The Committee may not, however, increase the Section 162(m) Pool, or the maximum amount permitted to be paid to any individual under Section 4.1 or 4.3 of the Plan for any Performance Period.

4.7 Committee Certification.    No Executive shall receive any payment under the Plan unless the Committee has certified, by resolution or other appropriate action in writing, that the amount thereof has been accurately determined in accordance with the terms, conditions and limits of the Plan and that the material terms previously established by the Committee or set forth in the Plan were in fact satisfied.

4.8 Time of Payment; Deferred Amounts.    Any Bonuses under the Plan shall be paid as soon as practicable (generally within seventy-five (75) days) following the Committee’s determinations under this Section 4.8 and the certification of the Committee’s findings under Section 4.7. Any such payment shall be in cash or cash equivalent or in such other form of equal value on such payment date (including Shares, Restricted Stock, or share equivalents as contemplated by Section 4.9) as the Committee may approve or require, subject to applicable withholding requirements (as provided in Section 4.10) and, if applicable, Section 4.9. Notwithstanding the foregoing, the Committee, in its sole discretion (but subject to compliance with Section

B-4

162(m), to compliance with Section 409A of the Code, and to any prior written commitments and to any conditions consistent with Sections 3.3, 4.9 and 6.10 that it deems appropriate), provide to Participants the opportunity to elect to defer the payment of any Bonus under a nonqualified deferred compensation plan.

4.9 Share Payouts of Bonus.    Any Shares, Restricted Stock, or Share-related stock unit payable under a Bonus shall be pursuant to a combined Award under the Plan and the Stock Plan. The number of Shares, Restricted Stock, or stock units (or similar deferred award representing a right to receive Shares) awarded in lieu of all or any portion of a Bonus shall be equal to the largest whole number of Shares which have an aggregate fair market value no greater than the amount of cash otherwise payable as of the date the cash payment of the Bonus would have been made. For this purpose, “fair market value” shall have the meaning set forth in the Stock Plan. Any such Shares, Restricted Stock, or stock units (or similar rights) shall thereafter be subject to adjustments for changes in corporate capitalization as provided in the Stock Plan.

4.10 Tax Withholding.    The Company shall withhold from any amounts payable under this Plan, or from any other compensation payable to the Participant, any and all federal, state and local income taxes, the Participant’s share of FICA and other employment taxes, and any other taxes that are required to be withheld from such payment under applicable law.

4.11 Unpaid Leave of Absence.    If a Participant takes an unpaid leave of absence from the Company or a Subsidiary, at the discretion of the Committee, the Bonus may be proportionately adjusted based on the period of Participant’s actual service during the Performance Period.

5.    Vesting and Termination of Awards

5.1 Vesting or Termination.    Except as otherwise set forth in the Plan, in the event the Participant’s employment with the Company and its Subsidiaries terminates during a Performance Period or thereafter prior to payment of Bonuses relating thereto, each Award shall be vested or shall terminate on such terms and conditions as the Committee shall establish- with respect to the Award.

5.2 Termination of Employment for Cause.    If a Participant’s employment with the Company or a Subsidiary is terminated for Cause or if a Participant engages in misconduct defined as Cause either before voluntary terminating employment or after terminating employment, any Award held by such Participant shall terminate immediately upon the Company giving notice to the Participant either that the Participant has been terminated for Cause or that the Participant has engaged in misconduct defined as Cause. The Committee shall be the sole judge of whether the Participant’s employment is terminated for Cause or the Participant has engaged in misconduct defined as Cause.

5.3 Termination of Employment due to Death and Disability.    If a Participant’s employment with the Company or a Subsidiary is terminated due to death or Disability, then the Participant shall be eligible to receive payment of a pro-rated Award within ninety (90) days of the termination date, or such shorter or longer time period as may be determined by the Committee, but only to the extent that the Award was earned on the termination date. The pro-rated value of the Award shall be calculated based upon the target value of the individual Award, rather than the EIP Pool (as the EIP Pool may not be established prior to the payment date.)

5.4 Termination of Employment due to Retirement.    If a Participant’s employment with the Company or a Subsidiary is terminated due to retirement after attaining age sixty-two (62) years, then the Participant shall be eligible to receive a pro-rated Bonus based on actual performance at the end of the Performance Period, or such shorter period as may be determined by the Committee, in order to receive a pro-rated Bonus.

6.    General Provisions

6.1 No Right to Awards or Continued Employment.    Neither the establishment of the Plan nor the provision for or payment of any amounts hereunder nor any action of the Company (including, for purposes of this Section 6.1, any predecessor or subsidiary), the Board or the Committee in respect of the Plan shall be held

B-5

or construed to confer upon any person any legal right to receive, or any interest in, an Award or any other benefit under the Plan, or any legal right to be continued in the employ of the Company. The Company expressly reserves any and all rights to discharge an Executive in its sole discretion, without liability of any person, entity or governing body under the Plan or otherwise. Nothing in this Section 6.1, however, is intended to adversely affect any express independent right of any person under a separate employment agreement. Notwithstanding any other provision hereof and notwithstanding the fact that criteria have been attained and/or the individual maximum amounts hereunder have been calculated, the Company shall have no obligation to pay any Bonus hereunder nor to pay the maximum amount so calculated or any prorated amount based on service during the period, unless the Committee otherwise expressly provides by written contract or other written commitment.

6.2 Subsequent Awards.    The designation of a Participant for a Performance Period shall not in any manner entitle the Participant to receive an Award for the Performance Period. Moreover, designation of a Participant for a particular Performance Period shall not require designation of such Participant for any subsequent Performance Period, and designation of one Participant for any Performance Period shall not require designation of any other Participant in such Performance Period or in any other Performance Period.

6.3 Discretion of Company, Board and Committee.    Any decision made or action taken by the Company or by the Board or by the Committee arising out of or in connection with the creation, amendment, construction, administration, interpretation and effect of the Plan shall be within the absolute discretion of such entity and shall be conclusive and binding upon all persons. No member of the Committee shall have any liability for actions taken or omitted under the Plan by the member or any other person.

6.4 Arbitration.    All claims, disputes and other matters in question arising out of or relating to this Plan shall be resolved by binding arbitration before an arbitrator, selected by the mutual agreement of the parties, from the Judicial Arbitration and Mediation Services, Inc. (“JAMS”), in San Francisco, California. In the event JAMS is unable or unwilling to conduct the arbitration provided for under the terms of this paragraph, or has discontinued its business, the parties agree that an arbitrator, selected by the mutual agreement of the parties, from the American Arbitration Association (“AAA”), in San Francisco, California, shall conduct the binding arbitration referred to in this paragraph. Notice of the demand for arbitration shall be filed in writing with the other party to the dispute and with JAMS (or AAA, if necessary). In no event shall the demand for arbitration be made after the date when institution of legal or equitable proceedings based on such claim, dispute or other matter in question would be barred by the applicable statute of limitations. The arbitration shall be subject to commercial rules and procedures used or established by JAMS, or if there are none, the commercial rules and procedures used or established by AAA. Notwithstanding anything to the contrary in the JAMS (or AAA) rules and procedures, the arbitration shall provide for (i) written discovery and depositions adequate to give the parties access to documents and witnesses that are essential to the dispute and (ii) a written decision by the arbitrator that includes the essential findings and conclusions upon which the decision is based. Subject to Section 6.5 below, the parties shall bear their own costs and attorneys’ fees incurred in conducting the arbitration, and shall split equally the fees and administrative costs charged by the arbitrator and JAMS (or AAA) unless required otherwise by applicable law. Any award rendered by JAMS (or AAA) shall be final and binding upon the parties, and as applicable, their respective heirs, Beneficiaries, legal representatives, agents, successors and assigns, and may be entered in any court having jurisdiction thereof. Any arbitration hereunder shall be conducted in Palo Alto, California, unless otherwise agreed to by the parties.

6.5 Attorneys Fees.    In the event of any arbitration or litigation concerning any controversy, claim or dispute arising out of or relating to this Plan, the prevailing party shall be entitled to recover from the non-prevailing party reasonable expenses, attorneys’ fees and costs incurred in connection therewith or in the enforcement or collection of any judgment or award rendered therein. The “prevailing party” means the party determined by the arbitrator(s) or court, as the case may be, to have most nearly prevailed, even if such party did not prevail in all matters, not necessarily the one in whose favor a judgment is rendered.

6.6 No Funding of Plan.    The Company shall not be required to fund or otherwise segregate any cash or any other assets which may at any time be paid to Participants under the Plan. The Plan shall constitute an

B-6

“unfunded” plan of the Company. The Company shall not, by any provisions of the Plan, be deemed to be a trustee of any property, and any rights of any Participant or former Participant shall be no greater than those of a general unsecured creditor or shareholder of the Company, as the case may be.

6.7 Non-Transferability of Benefits and Interests.    Except as expressly provided by the Committee, no benefit payable under the Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any such attempted action shall be void and no such benefit shall be in any manner liable for or subject to debts, contracts, liabilities, engagements or torts of any Participant or former Participant. This Section 6.7 shall not apply to an assignment of a contingency or payment due (i) after the death of an Participant to the deceased Participant’s legal representative or beneficiary or (ii) after the disability of a Participant to the disabled Participant’s personal representative.

6.8 Law to Govern.    All questions pertaining to the construction, regulation, validity and effect of the provisions of the Plan shall be determined in accordance with the laws of the State of California.

6.9 Non-Exclusivity.    The Plan does not limit the authority of the Company, the Board or the Committee, or any subsidiary of the Company to grant awards or authorize any other compensation to any person under any other plan or authority, including, without limitation, the issuance of restricted stock or restricted stock units or any other awards under the Stock Plan.

6.10 Section 162(m) Conditions; Bifurcation of Plan.    It is the intent of the Company that the Plan and Awards made hereunder satisfy and be interpreted in a manner, that, in the case of Participants who are persons whose compensation is subject to Section 162(m), satisfies any applicable requirements as performance-based compensation. Any provision, application or interpretation of the Plan inconsistent with this intent to satisfy the standards in Section 162(m) of the Code shall be disregarded. Notwithstanding anything to the contrary in the Plan, the provisions of the Plan may at any time be bifurcated by the Board or the Committee in any manner so that certain provisions of the Plan or any Bonus intended (or required in order) to satisfy the applicable requirements of Section 162(m) are only applicable to persons whose compensation is subject to Section 162(m).

7.    Amendment, Suspension or Termination

7.1 Amendment, Suspensions, or Termination of the Plan.    The Board or the Committee may from time to time amend, suspend or terminate in whole or in part, and if suspended or terminated, may reinstate, any or all of the provisions of the Plan. Notwithstanding the foregoing, no amendment shall be effective without Board and/or shareholder approval if such approval is necessary to comply with the applicable provisions of Section 162(m).

8.    Effective Date

8.1 Effective Date of the Plan.    The Plan shall be effective as of January 1, 2005, subject to the approval of the shareholders of the Company.
